While the era following the link Bland decision in 19931 might be thought of as the time when concepts such as ‘futility’ were placed under pressure and scrutiny, it’s an idea that has can i use ventolin when pregnant been debated for at least forty years. In a 1983 JME commentary Bryan Jennett distinguishes three kinds of reason why Cardiopulmonary Resuscitation (CPR) might be withheld:‘… that CPR would be futile because it is very unlikely to be successful. That quality of life after CPR is likely to be changed to so poor a level as to be a greater burden than the benefit gained from prolongation of life, and that quality of life is already so poor due to chronic or terminal disease that can i use ventolin when pregnant life should not be prolonged by CPR.’ pp-142-1432This crisp definition seems as applicable as it did then, but it was not the final word on the concept. Mitchell, Kerridge and Lovat explore, as others did in the post-Bland and Quinlan eras, how ‘futility’ might apply to those in a persistent vegetative state(PVS).3 They defend withdrawing artificial nutrition and hydration (ANH) when it ‘…offers no reasonable hope of real benefit to the PVS patient’ and note that this ‘would represent a significant shift in the ethical obligation owed by the doctor to the patient.’ p74 The ethical difference between that sense of futility and Jennett’s first sense of a ‘treatment being very unlikely to be successful’ was not lost on those critical of the withdrawal of ANH. Following the Bland decision, Finnis and Keown observed that doctors were now able to determine whether the life of someone in a PVS was worth living and decide that treatment could be withdrawn because treating that patient was deemed futile in the sense of not providing them with an improvement in their quality of life.4 5In addition to worries about the very different kinds of clinical judgement that can be described as futile, some have objected that the clinical use of the can i use ventolin when pregnant term risks being pejorative.

Gillon reaches the view that‘…futility judgments are so fraught with ambiguity, complexity and potential aggravation that they are probably best avoided altogether, at least in cases where the patient or the patient’s proxies are likely to disagree with the judgment.’6 p339Arguing in a similar vein, Ardagh objects both to the complexity in determining before the case that CPR won’t work and to the conceptual implication that futility means a failure of a treatment to benefit.7Futility has continued to be debated in the literature since these and other critical analyses of its utility and coherence were published. This issue of the JME includes papers that re-examine can i use ventolin when pregnant issues that were flagged in earlier debates. Cole et al describe the predicament faced by ambulance clinicians (paramedics) when they decide that CPR is futile and when family members are present who would like everything to be done.8 This brings back into the light the issue of whether the judgement that a treatment is futile is a straightforwardly clinical or physiological assessment. They mention can i use ventolin when pregnant UK guidance that says‘‘‘Where no explicit decision about CPR has been considered and recorded in advance, there should be an initial presumption in favour of CPR.” Clinicians are however, given discretion to make decisions not to attempt CPR where they think it would be futile.’That, on the face of it, implies that first responders can make a judgement that CPR is futile, but the picture is muddied if we understand futility to be a judgement about the best interests of that patient. That judgement does imply, at the very least, a discussion with family members about what would be in that patient’s interests.

So, clarity about which sense of futility is in play seems as critical as it did when Jennett wrote about it in the 1980s.Vivas and Carpenter grapple with the futility issue that was also at the heart of can i use ventolin when pregnant the Bland decision and the withdrawal of ANH for those in a PVS.9 They say‘How do we define treatment futility when a treatment is often effective in the strict physiological sense (restoring life) while being almost entirely ineffective in the larger, holistic sense—that is, it does not stop dying, merely delays and prolongs it?. €™In the case of CPR they consider the argument that it might be an instance of a death ritual ‘… connected with religious beliefs and broader social values. In our technological society, even ‘physiologically futile’ resuscitation may have significant value as social ritual for the dying and their loved ones.’ They are sensitive to the risks inherent in medicine offering treatments that are highly unlikely to benefit that patient because it helps those around can i use ventolin when pregnant the patient. They suggest that this may be a vital need nonetheless and the issue is therefore whether there are better ways of fulfilling these ‘existential needs’.Ethics statementsPatient consent for publicationNot required.IntroductionInternationally, pre-hospital registered ambulance clinicians (variously called ambulance clinicians, paramedics and emergency services personnel) are often put in the invidious position of having to make a decision about whether or not to attempt cardiopulmonary resuscitation (CPR) when they attend a call and find a patient whose heart has stopped. About 46% of deaths in the England occur in homes or nursing homes1 and ambulances are often called at times of health crisis, even when a death is expected, if caregivers feel unsure what to can i use ventolin when pregnant do.2 The call has been put out, the ambulance clinician has responded to the call.

To do nothing creates certainty around the individual’s death. Where the heart stopping is the final stage of a longer dying process, attempting CPR is likely to be futile, as the heart stopping reflects an overall physiological deterioration which CPR cannot can i use ventolin when pregnant reverse. In other circumstances, particularly in cases where the arrest is unexpected and the primary problem is with the heart, it may result in full recovery for the individual. Or it may give the individual a chance of returned circulation, but with can i use ventolin when pregnant great neurological deficit;3 or it may restart the heart briefly, only for the individual to die again.4The ambulance clinician must therefore make a rapid decision with potentially very significant repercussions. To protect them from the emotional work—and possible litigation—associated with these decisions, their recently updated UK professional guidance5 recommends.

€œWhere no explicit decision about CPR has been considered and recorded in advance, there should be an initial presumption in favour of CPR.” Clinicians are, however, given the can i use ventolin when pregnant discretion to make decisions not to attempt CPR where they think it would be futile, ‘for example, for a person in the advanced stages of a terminal illness where death is imminent and unavoidable’. However, there is no explicit mention of the importance of listening to family members’ views of what the patient would want, nor reference to the legal obligation of the ambulance clinician to follow the Mental Capacity Act 2005 (MCA 2005) and do what is in the patient’s best interests (which would involve taking into consideration what family members/friends and advocates think the patient would want). In the USA, guidance is not included on how to incorporate relatives’ views with best can i use ventolin when pregnant interests decisions. Ambulance clinicians have reported that they have not been taught to deal with these decisions6 and that it is often easier for them—both emotionally and logistically—to deliver attempted CPR than to consider withholding it. Relatives, who, after all, have been the ones to place can i use ventolin when pregnant the call in the first place, then feel powerless (and sometimes angry) when ambulance clinicians start CPR despite their protestations that this is ‘not what he/she would have wanted’.

In the USA, emergency services personnel have even less discretion than in the UK. In many states, they are bound to start CPR unless a specific Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) is in place, even if the patient has another can i use ventolin when pregnant kind of documentation, for example POLST (Physician Order for Life-Sustaining Treatment) until they have spoken to a ‘medical command physician’. They also must continue CPR if it has been started by a bystander even if a DNACPR is in place, until they are told they can stop by a physician.To highlight the moral discomfort experienced and the ethical and legal challenges faced, we present the perspectives of an ambulance clinician and a relative, and then review the legal and ethical framework in which they are operating, before concluding with some suggested changes to policy and guidance which we believe will protect ambulance clinicians, relatives and the patient.Ambulance clinician’s perspective—Rob ColeThe following is a case study to illustrate the grey area faced by ambulance clinicians when they consider they need to make a ‘best interests’ decision on a patient who has arrested. This is a composite case study from my experience of many such calls to protect the anonymity of those involved in any individual case.An emergency call can i use ventolin when pregnant was received by the ambulance emergency operations control room. At this stage, it was important to clarify the justification for this call as this directly influences any further decision making.

If the call was for the purpose of can i use ventolin when pregnant providing resuscitation to a patient in cardiorespiratory arrest then, as early as this stage, we can determine that at the point of call, somebody (accepting unable to qualify exactly whom) believes that the patient is either clinically indicated for resuscitation or someone believes they would desire or benefit from such an intervention. The caller identified that her husband was experiencing a seizure, and this had lasted for 5 min prior to her calling the ambulance. An ambulance was immediately despatched on this information alone (known as pre-alert dispatch). The location was some 4 min from the crew and they therefore arrived on the scene 5 min post call (in fact, on the crew arrival, the caller was still on the can i use ventolin when pregnant phone with the ambulance control centre).The crew were met by a female in her 70s (call with control ended on crew arrival). The crew were, as often is the case, provided with no further details other than that of a male in his 80s with a prolonged seizure.

The ambulance had travelled under emergency conditions can i use ventolin when pregnant to the address. The female greeted the crew (who had approached the property with full life-saving emergency equipment). She stated “I can i use ventolin when pregnant think he has gone” in a calm and clear voice. She allowed the crew into her home and quickly explained (during the journey to the patient, who is on a bed in the dining room downstairs) that the patient was her husband, that he had been generally unwell for some time (increased frailty, heart failure and developing dementia) and while she had not expected him to die at this point in time, she was not particularly surprised that he had. One member of the crew (double can i use ventolin when pregnant crew) prepared the patient for resuscitation, post a period of assessment while the other crew member continued to speak with the patient’s wife to better understand the situation.

The scene looked non-suspicious. The patient was lying peacefully (not breathing and with no heart rate) on can i use ventolin when pregnant a bed downstairs, dressed in pyjamas. The patient presented as frail in appearance but other than that, there was no further information of note.The member of the crew that spoke with the wife of the patient and ascertained that the patient was being treated by a general physician for a simple urinary tract , that there was no DNACPR in place as there was no specific requirement for one to have been put in place. No advance decision to refuse treatment can i use ventolin when pregnant (the female had no idea what this was) nor was there any legal power of attorney (the patient until this point had been broadly of sound mind with occasional episodes of confusion). As the other member of the ambulance crew commenced resuscitation (CPR), the patient’s wife angrily stated that her husband would not wish for this, nor did she or any member of her family.

She reiterated that the 999 call was due to a seizure, and had it been for the purpose of providing resuscitation, she would not have called the emergency services and all agreed that this was not can i use ventolin when pregnant the wish of the patient. Accepting this is not documented anywhere, the patient’s wife explained that these were conversations that had taken place within the family environment, that her husband had a clear view that he would not want to be subjected to any resuscitative efforts should he die, and funeral arrangements had been explored recently by all.To add, the patient’s wife appeared to be of sound mind, no obvious level of confusion and not in any particular state of heightened distress. The son of the patient was 10 min can i use ventolin when pregnant away from the address and on his way. A neighbour had also arrived at the property.To summarise, cardiac arrest of a patient in his 80s, not expected to die but family not surprised (had been quite unwell recently), no DNACPR or other documented evidence of the patient’s thoughts, click reference wishes and beliefs. Call for emergency help was to manage a seizure and NOT provide resuscitation.Family carer perspective—Mike StoneWhen my mother died about 10 years ago,7 I might have found myself as a relative trying to prevent a 999 paramedic from attempting CPR, but in the event, I found myself being ‘confronted by’ 999 personnel who seemed unable to understand why when my mum died at the end of a peaceful 4-day terminal coma, I had can i use ventolin when pregnant NOT felt the need ‘to phone someone immediately’.

This prompted me to embark on an investigation into end-of-life (EoL) guidance, protocols, mindsets and laws, which revealed to me a situation I can, at best, describe as urgently requiring improvement, especially but not exclusively for EoL-at-home, and which, in complex and confusing situations, protects professionals at the expense of damaging relatives and, sometimes, even patients.From my family carer perspective, this situation has to change. And, the direction of change must be one which improves the support can i use ventolin when pregnant given to patients, by promoting integration between everyone, lay and professional, involved in supporting patients. This ‘model’ requires ‘us and us’ as opposed to ‘us and them’. It emphasises teamwork can i use ventolin when pregnant between family carers and the clinicians who are in regular and ongoing contact with the patient, and it replaces ‘multidisciplinary team thinking’, with genuine professional-lay integration.Anyone can listen to a patient—provided you are present to listen. If only a relative is present, only the relative can listen.

Often it will require a clinician, such as a 999 paramedic, to confirm that a patient is in cardiopulmonary arrest, but the family carer who called 999, is the person most likely to know if the can i use ventolin when pregnant patient would have wanted CPR. Put simply, the clinicians are the experts in the clinical aspects, and the family and friends are the experts in ‘the patient as an individual’.I believe the current guidance around CPR decision-making is unsatisfactory and incoherent, and must be made more sensible and coherent.8–10 Contemporary protocols for ‘expected death’ are also fundamentally flawed.11 Advance decisions often fail to achieve the patient’s objective, apparently because clinicians are risk-averse.12I have only mentioned a few of the more significant problems, and those I have mentioned could, in theory, be addressed by consensus followed by improved training. Other fundamental problems—notably the fact that can i use ventolin when pregnant relatively few people have personal experience of caring for a loved one all the way to a death at home—are more problematic.To close this brief and personal analysis, I will give two opinions. The first is that the change required is easy to see, and involves things such as more group-based and ‘diffusely achieved’ decision-making instead of identifiable individuals being invariably associated with and responsible for specific decisions. But it is can i use ventolin when pregnant a change which a hierarchical and process/records-based National Health Service (NHS) would really struggle to come to terms with.13The second is my optimism that growing pressure from patients and relatives will make the changes in behaviour inevitable, because, perhaps surprisingly, of social media.14Legal analysis—Alex Ruck KeeneMike’s experiences speak clearly of the practical problems caused by paramedics misunderstanding the law.If there is a situation in which CPR would simply not work to restart the heart or breathing, then the paramedics would be under no duty to attempt it, as there is no duty to seek to carry out a futile procedure.

However, if it appeared that it might work, then the paramedics are, in England and Wales, governed by the MCA 2005. In practice, the realities confronted by paramedics are such can i use ventolin when pregnant that the majority of their decision-making will be governed by the MCA 2005. This Act provides a framework for decision-making in relation to those with impaired decision-making capacity which is (unlike legal frameworks in some other jurisdictions) not predicated on there being an automatic proxy decision-maker, such as a ‘next of kin.’ Rather, the Act provides (in s.5) that any person—such as a paramedic—is able to carry out an act of care and treatment in relation to another (‘P’) with protection from liability if they. (1) take reasonable steps to determine whether P has the capacity to consent can i use ventolin when pregnant to the act. And (2) if P lacks capacity, that they reasonably believe that they are acting in P’s best interests.In all situations, the first step is to consider whether the person has capacity to make their own decision—to consent to or refuse CPR.

In the scenario presented by Rob Cole, as with almost all situations where CPR is required, the patient was unconscious and there were no practicable steps that could be taken to support him within the time available. Reaching the conclusion that the patient did not have capacity could therefore have been effectively instantaneous.The paramedics had taken reasonable steps to ascertain whether the person had made an advance decision to refuse CPR (as a medical treatment), and that he had not can i use ventolin when pregnant made one.This means that they were therefore required to decide whether it was in his best interests for them to attempt it.‘Best interests’ is, deliberately, not defined in the MCA 2005. However, s.4 sets out a series of matters that must be considered whenever a person is determining what is in the person’s best interests to allow them to have a reasonable belief as to they are acting in those best interests. It is extremely important to recognise that the MCA 2005 does not specify what is in can i use ventolin when pregnant the person’s best interests. Rather, it sets down a process by which that conclusion should be reached, which recognises that a lack of decision-making capacity is not an ‘off-switch’ for their rights and freedom (Wye Valley NHS Trust v- Mr B ]2015[ EWCOP 60 in paragraph 11).

The process aims to construct a can i use ventolin when pregnant decision on behalf of the person who cannot make that decision themselves. As the Supreme Court emphasised in Aintree University NHS Hospitals Trust v James [2014] UKSC 67 “[t]he purpose of the best interests test is to consider matters from the patient’s point of view.” It is critically important to understand that the purpose of the decision-making process is to try to arrive at the decision that is the right decision for the person themselves, as an individual human being, and not the decision that best fits with the outcome that the professionals desire. Any information about the patient’s wishes, feelings, beliefs and values will be relevant, including, in particular, preferences and recommendations documented when the person had capacity.Consultation will can i use ventolin when pregnant also be required with those who could shed light on the person’s likely decision, here his wife. The case of Winspear v City Hospitals Sunderland NHS Foundation Trust [2015] EWHC 3250 (QB) made clear that a failure to consult where it is practicable and appropriate will mean that professionals cannot then rely on the defence in s.5 of MCA to what might otherwise be criminal acts.In making a best interests decision about giving life-sustaining treatment, there is always a strong presumption that it will be in the patient’s best interests to prolong his or her life, and the decision-maker must not be motivated by a desire to bring about the person’s death for whatever reason, even if this is from a sense of compassion. However, the strong presumption in favour of prolonging life can be displaced where:There is clear evidence can i use ventolin when pregnant that the person would not want the treatment in question in the circumstances that have arisen.The treatment itself would be overly burdensome for the patient, in particular by reference to whether the patient accepts invasive and uncomfortable interventions or prefers to be kept comfortable.There is no prospect that the treatment will return the patient to a state of a quality of life that the patient would regard as worthwhile.

The important viewpoint is that of the patient, not of the doctors or healthcare professionals.Case law has made clear that the weight that is to be attached to the reliably ascertainable views of the person should be given very substantial, if not determinative, weight (Re AB (Termination of Pregnancy) [2019) EWCA Civ 1215]. In a case such as that described in the scenario of the can i use ventolin when pregnant ambulance clinician, and given the clarity of the views expressed by the man’s wife in relation to what he would have wanted, the paramedics could properly conclude that attempting CPR was not in his best interests. The Supreme Court has confirmed that they should not then attempt it. NHS Trust v Y [2018] UKSC 22.Drawing the legal threads together, therefore, in a situation such as this:Unless the paramedics have a proper reason to doubt the good faith of can i use ventolin when pregnant the family member present, they should proceed on the basis that they are reliable in relaying what the person would have wanted.The paramedics can then either start or not start CPR accordingly because they have the necessary reasonable belief that they are acting in the person’s best interests.If there is reason to doubt the good faith of the family member present, or the family member does not (or cannot) relay clear views, the paramedics should start CPR. It may be that after they have started, they are able to glean further information which makes the picture clearer and enables them to decide whether continuing is in the patient’s best interests.Ethical overview and proposals for change—Zoë Fritz (and other authors)Law, ethical principles and professional clinical guidelines influence each other.15 In an ideal system, this would ensure just care with recognition of the rights of practitioners and patients.

When it works badly, can i use ventolin when pregnant the ‘letter of the law’ is followed, even when it runs counter to good ethics, with potentially devastating personal consequences. The composite scenario and personal events, described above by an ambulance clinician and a family member, reflect examples of where medical practitioners believed they were following the law, but where their actions could be argued to have been unethical.In contrast, a related example of the law working positively to overturn accepted clinical guidance and practice, is around the need to discuss a decision not to attempt CPR with a patient. The 2007 joint guidance issued by the British Medical Association, Royal can i use ventolin when pregnant College of Nursing and the Resuscitation Council (UK) (2007) stated. €œWhen a clinical decision is made that CPR should not be attempted, because it will not be successful, and the patient has not expressed a wish to discuss CPR, it is not necessary or appropriate to initiate discussion with the patient to explore their wishes regarding CPR.” The case of Janet Tracey challenged this. The judges in the court of appeal found that not discussing a decision to withhold CPR with a patient was in breach of their human rights (Article 8 European Convention on Human Rights) as it deprived them of the right to question the clinical decision or ask can i use ventolin when pregnant for a second opinion, particularly in the context of a potentially life-saving treatment.16 Clinicians rapidly changed their practice.

In fact, the whole nature of CPR conversations was altered to ensure that it was not considered in isolation, but always discussed within overall goals of care. In being forced to discuss CPR with patients, doctors reconsidered the conversation, what it meant and when it could and should occur.17The ReSPECT (Recommended Summary Plan for Emergency Care and Treatment) process emerged from this as a way of nudging doctors and patients into having better conversations and documentation of agreed recommendations;18 it is now used in more than 130 trusts.19While, at first glance, there may appear to be ethical and legal tensions in the scenarios described above, it is possible that good training and professional guidance can i use ventolin when pregnant would dispel them. If families were better supported to understand what may happen where a loved one dies at home, they would be better equipped to deal with the crisis when it came. Specific resources are needed can i use ventolin when pregnant. If, for example, there had been a specific number to call for an expected death, other than 999, in the two deaths reported here, then neither of these upsetting scenarios would have occurred.

As mentioned above, social media may be another positive force in both applying pressure for change, and in acting as a leveller in terms of access to information.If the professional guidance and other material—published by Joint Royal can i use ventolin when pregnant Colleges Ambulance Liaison Committee, Royal College of Nursing, Resuscitation Council UK and so on—stated clearly that, where death was expected and CPR appeared to be futile, even in the absence of a DNACPR or ReSPECT form, an ambulance clinician or qualified nurse could decide that attempting CPR was clinically pointless or potentially harmful, then clinicians would not need to choose between what they considered morally right and what they had to do to protect their professional registration.The new JRCALC guidance takes this into account, and it is likely that other guidance will also be explicit about this in the future. They should also be explicit about the role of the MCA and best interests decisions. An honest carer, family member who protests, “… but my husband would definitely can i use ventolin when pregnant not want CPR—don’t do that!. € may be perceived as applying the MCA to her own determination of what is in her husband’s best interests, even if the wife has no awareness of the MCA.If the ambulance clinicians were taught clearly that acting in the patient’s ‘best interests’ in this scenario most often meant doing as the relatives asked, then the (frequently internalised) concern that they were choosing between what was right for the patient and what was right for the patient’s relative would be abolished, and the associated moral discomfort diminished. We recognise that there will, in some cases, be a different tension—where the ambulance clinician considers that the CPR will not be successful but the relatives want it can i use ventolin when pregnant to take place.

But this is where the distinction between the ambulance clinician as the expert in the medical procedure and the relative as the expert in the person comes in—nobody can demand medical treatment which is inappropriate, and CPR is no different.The guidance and the training should emphasise the teawork which Mike Stone mentions above. The default assumption should be that clinicians and relatives have a shared goal of what is best for the patient, and work together as ‘us and us’ as opposed to ‘us and them’.Data availability statementThere are no data in this work.Ethics statementsPatient consent for publicationNot required..

They also must continue CPR if it has been started by a bystander even if a DNACPR is in place, until they are told they can stop by a physician.To highlight the moral discomfort experienced and the ethical and legal challenges faced, we present the perspectives of an ambulance clinician and a relative, and then review the legal and ethical framework in which they are operating, before concluding with some suggested changes to policy and guidance which we believe will protect ambulance clinicians, relatives and the patient.Ambulance clinician’s perspective—Rob ColeThe following is a case study to illustrate the grey area faced by ambulance clinicians when they consider they need to make a ‘best interests’ decision on a patient who has arrested.

This is a composite case study from my experience of many such calls to protect the anonymity of those involved in any individual case.An emergency call was received by the ambulance cheap ventolin online canada emergency operations control room. At this stage, it was important to clarify the justification for this call as this directly influences any further decision making. If the call was for the purpose of providing resuscitation to a patient in cardiorespiratory arrest then, as early as this stage, we can determine that at the point of call, somebody (accepting unable to qualify exactly whom) believes that the patient is either clinically indicated for resuscitation or cheap ventolin online canada someone believes they would desire or benefit from such an intervention. The caller identified that her husband was experiencing a seizure, and this had lasted for 5 min prior to her calling the ambulance.

An ambulance was immediately despatched on this information alone (known as pre-alert dispatch). The location was some 4 min from the crew and they therefore arrived on the scene 5 min post call (in fact, on the crew arrival, the caller was still on the phone cheap ventolin online canada with the ambulance control centre).The crew were met by a female in her 70s (call with control ended on crew arrival). The crew were, as often is the case, provided with no further details other than that of a male in his 80s with a prolonged seizure. The ambulance had travelled cheap ventolin online canada under emergency conditions to the address.

The female greeted the crew (who had approached the property with full life-saving emergency equipment). She stated cheap ventolin online canada “I think he has gone” in a calm and clear voice. She allowed the crew into her home and quickly explained (during the journey to the patient, who is on a bed in the dining room downstairs) that the patient was her husband, that he had been generally unwell for some time (increased frailty, heart failure and developing dementia) and while she had not expected him to die at this point in time, she was not particularly surprised that he had. One member of the crew (double crew) prepared the patient for resuscitation, post a period of assessment while the other crew member continued to speak with the patient’s wife to better understand the situation cheap ventolin online canada.

The scene looked non-suspicious. The patient was lying cheap ventolin online canada peacefully (not breathing and with no heart rate) on a bed downstairs, dressed in pyjamas. The patient presented as frail in appearance but other than that, there was no further information of note.The member of the crew that spoke with the wife of the patient and ascertained that the patient was being treated by a general physician for a simple urinary tract , that there was no DNACPR in place as there was no specific requirement for one to have been put in place. No advance decision to refuse treatment (the female had no idea what this was) nor was there any legal power of attorney (the patient until this point had been broadly of sound cheap ventolin online canada mind with occasional episodes of confusion).

As the other member of the ambulance crew commenced resuscitation (CPR), the patient’s wife angrily stated that her husband would not wish for this, nor did she or any member of her family. She reiterated cheap ventolin online canada that the 999 call was due to a seizure, and had it been for the purpose of providing resuscitation, she would not have called the emergency services and all agreed that this was not the wish of the patient. Accepting this is not documented anywhere, the patient’s wife explained that these were conversations that had taken place within the family environment, that her husband had a clear view that he would not want to be subjected to any resuscitative efforts should he die, and funeral arrangements had been explored recently by all.To add, the patient’s wife appeared to be of sound mind, no obvious level of confusion and not in any particular state of heightened distress. The son of the patient was 10 min away from the address cheap ventolin online canada and on his way.

A neighbour had also arrived at the property.To summarise, cardiac arrest of a patient in his 80s, not expected https://elvisknight.co.uk/blog/ to die but family not surprised (had been quite unwell recently), no DNACPR or other documented evidence of the patient’s thoughts, wishes and beliefs. Call for emergency help was to manage a seizure and NOT provide resuscitation.Family carer perspective—Mike StoneWhen my mother died about 10 years ago,7 I might have found myself as a relative trying to prevent a 999 paramedic from attempting CPR, but in the event, I found myself being ‘confronted by’ 999 personnel who seemed unable to understand why when my mum died at the end of a peaceful 4-day terminal coma, I had NOT cheap ventolin online canada felt the need ‘to phone someone immediately’. This prompted me to embark on an investigation into end-of-life (EoL) guidance, protocols, mindsets and laws, which revealed to me a situation I can, at best, describe as urgently requiring improvement, especially but not exclusively for EoL-at-home, and which, in complex and confusing situations, protects professionals at the expense of damaging relatives and, sometimes, even patients.From my family carer perspective, this situation has to change. And, the direction of change must be one which improves the support given to patients, by promoting integration between cheap ventolin online canada everyone, lay and professional, involved in supporting patients.

This ‘model’ requires ‘us and us’ as opposed to ‘us and them’. It emphasises teamwork between family carers and the clinicians who are in regular and ongoing contact with the patient, and cheap ventolin online canada it replaces ‘multidisciplinary team thinking’, with genuine professional-lay integration.Anyone can listen to a patient—provided you are present to listen. If only a relative is present, only the relative can listen. Often it will require a clinician, such as a 999 paramedic, to confirm that a patient is in cardiopulmonary arrest, but the family carer who called 999, is the person most likely to know if the patient would cheap ventolin online canada have wanted CPR.

Put simply, the clinicians are the experts in the clinical aspects, and the family and friends are the experts in ‘the patient as an individual’.I believe the current guidance around CPR decision-making is unsatisfactory and incoherent, and must be made more sensible and coherent.8–10 Contemporary protocols for ‘expected death’ are also fundamentally flawed.11 Advance decisions often fail to achieve the patient’s objective, apparently because clinicians are risk-averse.12I have only mentioned a few of the more significant problems, and those I have mentioned could, in theory, be addressed by consensus followed by improved training. Other fundamental problems—notably the fact that relatively few people have personal experience of caring for a loved one all the way to a death at home—are more problematic.To cheap ventolin online canada close this brief and personal analysis, I will give two opinions. The first is that the change required is easy to see, and involves things such as more group-based and ‘diffusely achieved’ decision-making instead of identifiable individuals being invariably associated with and responsible for specific decisions. But it is a change which a hierarchical and process/records-based National Health Service (NHS) would really struggle to come to terms with.13The second is my optimism that growing pressure from patients and relatives cheap ventolin online canada will make the changes in behaviour inevitable, because, perhaps surprisingly, of social media.14Legal analysis—Alex Ruck KeeneMike’s experiences speak clearly of the practical problems caused by paramedics misunderstanding the law.If there is a situation in which CPR would simply not work to restart the heart or breathing, then the paramedics would be under no duty to attempt it, as there is no duty to seek to carry out a futile procedure.

However, if it appeared that it might work, then the paramedics are, in England and Wales, governed by the MCA 2005. In practice, the realities confronted by paramedics are such cheap ventolin online canada that the majority of their decision-making will be governed by the MCA 2005. This Act provides a framework for decision-making in relation to those with impaired decision-making capacity which is (unlike legal frameworks in some other jurisdictions) not predicated on there being an automatic proxy decision-maker, such as a ‘next of kin.’ Rather, the Act provides (in s.5) that any person—such as a paramedic—is able to carry out an act of care and treatment in relation to another (‘P’) with protection from liability if they. (1) take reasonable steps to determine whether P has the capacity to consent cheap ventolin online canada to the act.

And (2) if P lacks capacity, that they reasonably believe that they are acting in P’s best interests.In all situations, the first step is to consider whether the person has capacity to make their own decision—to consent to or refuse CPR. In the scenario presented by Rob Cole, as with almost all situations where CPR is required, the patient was unconscious and there were no practicable steps that could be taken to support him within the time available. Reaching the conclusion that the patient did not have capacity could therefore have been effectively instantaneous.The paramedics had taken reasonable steps to ascertain whether the person had made an advance decision cheap ventolin online canada to refuse CPR (as a medical treatment), and that he had not made one.This means that they were therefore required to decide whether it was in his best interests for them to attempt it.‘Best interests’ is, deliberately, not defined in the MCA 2005. However, s.4 sets out a series of matters that must be considered whenever a person is determining what is in the person’s best interests to allow them to have a reasonable belief as to they are acting in those best interests.

It is extremely important to recognise that the MCA cheap ventolin online canada 2005 does not specify what is in the person’s best interests. Rather, it sets down a process by which that conclusion should be reached, which recognises that a lack of decision-making capacity is not an ‘off-switch’ for their rights and freedom (Wye Valley NHS Trust v- Mr B ]2015[ EWCOP 60 in paragraph 11). The process aims to construct cheap ventolin online canada a decision on behalf of the person who cannot make that decision themselves. As the Supreme Court emphasised in Aintree University NHS Hospitals Trust v James [2014] UKSC 67 “[t]he purpose of the best interests test is to consider matters from the patient’s point of view.” It is critically important to understand that the purpose of the decision-making process is to try to arrive at the decision that is the right decision for the person themselves, as an individual human being, and not the decision that best fits with the outcome that the professionals desire.

Any information about the patient’s wishes, feelings, beliefs and values will be relevant, including, in particular, cheap ventolin online canada preferences and recommendations documented when the person had capacity.Consultation will also be required with those who could shed light on the person’s likely decision, here his wife. The case of Winspear v City Hospitals Sunderland NHS Foundation Trust [2015] EWHC 3250 (QB) made clear that a failure to consult where it is practicable and appropriate will mean that professionals cannot then rely on the defence in s.5 of MCA to what might otherwise be criminal acts.In making a best interests decision about giving life-sustaining treatment, there is always a strong presumption that it will be in the patient’s best interests to prolong his or her life, and the decision-maker must not be motivated by a desire to bring about the person’s death for whatever reason, even if this is from a sense of compassion. However, the strong presumption in favour of prolonging life can be displaced where:There is clear evidence that the person would not want the treatment in question in the circumstances that have arisen.The treatment itself would be overly burdensome for the patient, in particular by reference to whether the patient accepts invasive and uncomfortable interventions or prefers to be kept cheap ventolin online canada comfortable.There is no prospect that the treatment will return the patient to a state of a quality of life that the patient would regard as worthwhile. The important viewpoint is that of the patient, not of the doctors or healthcare professionals.Case law has made clear that the weight that is to be attached to the reliably ascertainable views of the person should be given very substantial, if not determinative, weight (Re AB (Termination of Pregnancy) [2019) EWCA Civ 1215].

In a case such as that described in the cheap ventolin online canada scenario of the ambulance clinician, and given the clarity of the views expressed by the man’s wife in relation to what he would have wanted, the paramedics could properly conclude that attempting CPR was not in his best interests. The Supreme Court has confirmed that they should not then attempt it. NHS Trust v Y [2018] UKSC 22.Drawing the legal threads together, therefore, in a situation such as this:Unless the paramedics have a proper reason to doubt the good faith of the family member present, they should proceed on the basis that they are reliable in relaying what the person would have wanted.The paramedics can then cheap ventolin online canada either start or not start CPR accordingly because they have the necessary reasonable belief that they are acting in the person’s best interests.If there is reason to doubt the good faith of the family member present, or the family member does not (or cannot) relay clear views, the paramedics should start CPR. It may be that after they have started, they are able to glean further information which makes the picture clearer and enables them to decide whether continuing is in the patient’s best interests.Ethical overview and proposals for change—Zoë Fritz (and other authors)Law, ethical principles and professional clinical guidelines influence each other.15 In an ideal system, this would ensure just care with recognition of the rights of practitioners and patients.

When it cheap ventolin online canada works badly, the ‘letter of the law’ is followed, even when it runs counter to good ethics, with potentially devastating personal consequences. The composite scenario and personal events, described above by an ambulance clinician and a family member, reflect examples of where medical practitioners believed they were following the law, but where their actions could be argued to have been unethical.In contrast, a related example of the law working positively to overturn accepted clinical guidance and practice, is around the need to discuss a decision not to attempt CPR with a patient. The 2007 joint guidance issued by the British Medical Association, Royal College of Nursing cheap ventolin online canada and the Resuscitation Council (UK) (2007) stated. €œWhen a clinical decision is made that CPR should not be attempted, because it will not be successful, and the patient has not expressed a wish to discuss CPR, it is not necessary or appropriate to initiate discussion with the patient to explore their wishes regarding CPR.” The case of Janet Tracey challenged this.

The judges in the court of appeal cheap ventolin online canada found that not discussing a decision to withhold CPR with a patient was in breach of their human rights (Article 8 European Convention on Human Rights) as it deprived them of the right to question the clinical decision or ask for a second opinion, particularly in the context of a potentially life-saving treatment.16 Clinicians rapidly changed their practice. In fact, the whole nature of CPR conversations was altered to ensure that it was not considered in isolation, but always discussed within overall goals of care. In being forced to discuss CPR with patients, doctors reconsidered the conversation, what it meant and when it could and should occur.17The ReSPECT (Recommended Summary Plan for Emergency Care and Treatment) process emerged from this as a way of nudging doctors and patients into cheap ventolin online canada having better conversations and documentation of agreed recommendations;18 it is now used in more than 130 trusts.19While, at first glance, there may appear to be ethical and legal tensions in the scenarios described above, it is possible that good training and professional guidance would dispel them. If families were better supported to understand what may happen where a loved one dies at home, they would be better equipped to deal with the crisis when it came.

Specific resources are needed cheap ventolin online canada. If, for example, there had been a specific number to call for an expected death, other than 999, in the two deaths reported here, then neither of these upsetting scenarios would have occurred. As mentioned above, social media may be another positive force in both applying pressure for change, and in acting as a leveller in terms of access to information.If the professional guidance and other material—published by Joint Royal Colleges Ambulance Liaison Committee, Royal College of Nursing, Resuscitation Council UK and so on—stated clearly that, where death was expected and CPR appeared to be futile, even in the absence of a DNACPR or ReSPECT form, an ambulance clinician or qualified nurse could decide that attempting CPR cheap ventolin online canada was clinically pointless or potentially harmful, then clinicians would not need to choose between what they considered morally right and what they had to do to protect their professional registration.The new JRCALC guidance takes this into account, and it is likely that other guidance will also be explicit about this in the future. They should also be explicit about the role of the MCA and best interests decisions.

An honest carer, family member who protests, cheap ventolin online canada “… but my husband would definitely not want CPR—don’t do that!. € may be perceived as applying the MCA to her own determination of what is in her husband’s best interests, even if the wife has no awareness of the MCA.If the ambulance clinicians were taught clearly that acting in the patient’s ‘best interests’ in this scenario most often meant doing as the relatives asked, then the (frequently internalised) concern that they were choosing between what was right for the patient and what was right for the patient’s relative would be abolished, and the associated moral discomfort diminished. We recognise that there will, in some cases, be a different tension—where the ambulance clinician considers that the CPR cheap ventolin online canada will not be successful but the relatives want it to take place. But this is where the distinction between the ambulance clinician as the expert in the medical procedure and the relative as the expert in the person comes in—nobody can demand medical treatment which is inappropriate, and CPR is no different.The guidance and the training should emphasise the teawork which Mike Stone mentions above.

The default assumption should be that clinicians and relatives have a shared goal of what is best for the patient, and work together as ‘us and us’ as opposed to ‘us and them’.Data availability statementThere are no data in this work.Ethics statementsPatient consent for publicationNot required..

Ventolin generic

Study Design and Participants To reduce the risk of introducing asthma into basic training at Marine Corps Recruit Depot, Parris Island, in South ventolin generic Carolina, the Marine Corps established a 14-day supervised quarantine period at a college campus used exclusively for this purpose. Potential recruits were instructed to quarantine at home for 2 weeks immediately before they traveled to campus. At the end of the second, ventolin generic supervised quarantine on campus, all recruits were required to have a negative qPCR result before they could enter Parris Island. Recruits were asked to participate in the asthma treatment Health Action Response for Marines (CHARM) study, which included weekly qPCR testing and blood sampling for IgG antibody assessment. After potential recruits had completed the 14-day home quarantine, they presented to a local Military Entrance Processing Station, where a medical history was taken and a physical examination was performed.

If potential recruits were deemed to be physically and mentally fit for enlistment, they were instructed to ventolin generic wear masks at all times and maintain social distancing of at least 6 feet during travel to the quarantine campus. Classes of 350 to 450 recruits arrived on campus nearly weekly. New classes were divided into platoons of 50 to 60 recruits, and roommates were assigned independently of participation in the CHARM study. Overlapping classes were housed in different dormitories and had different ventolin generic dining times and training schedules. During the supervised quarantine, public health measures were enforced to suppress asthma transmission (Table S1 in the Supplementary Appendix, available with the full text of this article at NEJM.org).

All recruits wore double-layered cloth masks at all times indoors and outdoors, except when sleeping or eating. Practiced social distancing of at ventolin generic least 6 feet. Were not allowed to leave campus. Did not have access to personal electronics and other items that might contribute to surface transmission. And routinely ventolin generic washed their hands.

They slept in double-occupancy rooms with sinks, ate in shared dining facilities, and used shared bathrooms. All recruits cleaned their rooms daily, ventolin generic sanitized bathrooms after each use with bleach wipes, and ate preplated meals in a dining hall that was cleaned with bleach after each platoon had eaten. Most instruction and exercises were conducted outdoors. All movement of recruits was supervised, and unidirectional flow was implemented, with designated building entry and exit points to minimize contact among persons. All recruits, ventolin generic regardless of participation in the study, underwent daily temperature and symptom screening.

Six instructors who were assigned to each platoon worked in 8-hour shifts and enforced the quarantine measures. If recruits reported any signs or symptoms consistent with asthma treatment, they reported to sick call, underwent rapid qPCR testing for asthma, and were placed in isolation pending the results of testing. Instructors were also restricted to campus, were required to wear masks, were provided with preplated ventolin generic meals, and underwent daily temperature checks and symptom screening. Instructors who were assigned to a platoon in which a positive case was diagnosed underwent rapid qPCR testing for asthma, and, if the result was positive, the instructor was removed from duty. Recruits and instructors were prohibited from interacting with campus support staff, such as janitorial and food-service personnel.

After each class completed quarantine, a deep bleach cleaning of surfaces was performed in the bathrooms, showers, ventolin generic bedrooms, and hallways in the dormitories, and the dormitory remained unoccupied for at least 72 hours before reoccupancy. Within 2 days after arrival at the campus, after recruits had received assignments to platoons and roommates, they were offered the opportunity to participate in the longitudinal CHARM study. Recruits were eligible if they were 18 years of age or older and if they would be available for follow-up. The study was approved by the institutional review board of the Naval Medical Research Center and complied with ventolin generic all applicable federal regulations governing the protection of human subjects. All participants provided written informed consent.

Procedures At the time of enrollment, participants answered a questionnaire ventolin generic regarding demographic characteristics, risk factors for asthma , symptoms within the previous 14 days, and a brief medical history. Blood samples and mid-turbinate nares swab specimens were obtained for qPCR testing to detect asthma. Demographic information included sex, age, ethnic group, race, place of birth, and U.S. State or country of ventolin generic residence. Information regarding risk factors included whether participants had used masks, whether they had adhered to self-quarantine before arrival, their recent travel history, their known exposure to someone with asthma treatment, whether they had flulike symptoms or other respiratory illness, and whether they had any of 14 specific symptoms characteristic of asthma treatment or any other symptoms associated with an unspecified condition within the previous 14 days.

Study participants were followed up on days 7 and 14, at which time they reported any symptoms that had occurred within the past 7 days. Nares swab specimens for repeat qPCR ventolin generic assays were also obtained. Participants who had positive qPCR results were placed in isolation and were approached for participation in a related but separate study of infected recruits, which involved more frequent testing during isolation. All recruits who did not participate in the current study were tested for asthma only at the end of the 2-week quarantine, unless clinically indicated (in accordance with the public health procedures of the Marine Corps). Serum specimens obtained at enrollment were tested ventolin generic for asthma–specific IgG antibodies with the use of the methods described below and in the Supplementary Appendix.

Participants who tested positive on the day of enrollment (day 0) or on day 7 or day 14 were separated from their roommates and were placed in isolation. Otherwise, participants and nonparticipants were not treated ventolin generic differently. They followed the same safety protocols, were assigned to rooms and platoons regardless of participation in the study, and received the same formal instruction. Laboratory Methods The qPCR testing of mid-turbinate nares swab specimens for asthma was performed within 48 hours after collection by Lab24 (Boca Raton, FL) with the use of the TaqPath asthma treatment Combo Kit (Thermo Fisher Scientific), which is authorized by the Food and Drug Administration. Specimens obtained from nonparticipants ventolin generic were tested by the Naval Medical Research Center (Silver Spring, MD).

Specimens were stored in viral transport medium at 4°C. The presence of IgG antibodies specific to the asthma receptor-binding (spike) domain in serum specimens was evaluated with the use of an enzyme-linked immunosorbent assay, as previously described,10 with some modifications. At least two positive controls, eight negative controls (serum specimens obtained before July 2019), and four blanks (no serum) were included ventolin generic in every plate. Serum specimens were first screened at a 1:50 dilution, followed by full dilution series if the specimens were initially found to be positive. Whole-Genome Sequencing and Assembly asthma sequencing was performed with the use of two sequencing protocols (an Illumina sequencing protocol and an Ion Torrent sequencing protocol) to increase the likelihood of obtaining complete genome sequences.

A custom reference-based analysis pipeline (https://github.com/mjsull/asthma treatment_pipe) was used to assemble asthma genomes with the use of data from Illumina, Ion Torrent, or both.11 Phylogenetic Analysis asthma genomes obtained from patients worldwide and associated metadata were downloaded from the Global Initiative on Sharing All Influenza Data EpiCoV database12 on August 11, 2020 (79,840 sequences), and a subset of sequences was selected from this database with the use of the default subsampling scheme of Nextstrain software13 with the aim of maximizing representation of ventolin generic genomes obtained from patients in the United States. Phylogenetic analyses of the specimens obtained from participants were performed with the v1.0-292-ga9de690 Nextstrain build for asthma genomes with the use of default parameters. Transmission and outbreak events were identified on the basis of clustering of the asthma genomes obtained from study participants within the Nextstrain phylogenetic tree, visualized with TreeTime.14 A comparative analysis of mutation profiles relative to the asthma Wuhan reference genome was performed with the use of Nextclade software, version 0.3.6 (https://clades.nextstrain.org/). Data Analysis The denominator for calculating the percentage of recruits who had a first positive result for asthma by qPCR assay on each day of testing excluded recruits who had previously tested positive, had dropped out of the ventolin generic study, were administratively separated from the Marine Corps, or had missing data. The denominator for calculating the cumulative positivity rates included all recruits who had undergone testing at previous time points, including those who were no longer participating in the study.

Only descriptive numerical results and percentages are reported, with no formal statistical analysis..

Six instructors who were assigned to each platoon worked in 8-hour shifts and enforced the quarantine measures.

If recruits reported any signs or symptoms consistent with asthma treatment, they reported to sick call, underwent rapid qPCR testing for asthma, and were placed in isolation pending the results of testing. Instructors were also restricted to campus, were required to wear masks, were provided with preplated meals, and underwent daily temperature checks and cheap ventolin online canada symptom screening. Instructors who were assigned to a platoon in which a positive case was diagnosed underwent rapid qPCR testing for asthma, and, if the result was positive, the instructor was removed from duty.

Recruits and instructors were prohibited from interacting with campus support staff, such as janitorial and food-service personnel. After each class completed quarantine, a deep bleach cleaning of surfaces was performed in the bathrooms, showers, bedrooms, and hallways in the dormitories, and the dormitory remained unoccupied for at least 72 hours cheap ventolin online canada before reoccupancy. Within 2 days after arrival at the campus, after recruits had received assignments to platoons and roommates, they were offered the opportunity to participate in the longitudinal CHARM study.

Recruits were eligible if they were 18 years of age or older and if they would be available for follow-up. The study was approved by the institutional cheap ventolin online canada review board of the Naval Medical Research Center and complied with all applicable federal regulations governing the protection of human subjects. All participants provided written informed consent.

Procedures At the cheap ventolin online canada time of enrollment, participants answered a questionnaire regarding demographic characteristics, risk factors for asthma , symptoms within the previous 14 days, and a brief medical history. Blood samples and mid-turbinate nares swab specimens were obtained for qPCR testing to detect asthma. Demographic information included sex, age, ethnic group, race, place of birth, and U.S.

State or cheap ventolin online canada country of residence. Information regarding risk factors included whether participants had used masks, whether they had adhered to self-quarantine before arrival, their recent travel history, their known exposure to someone with asthma treatment, whether they had flulike symptoms or other respiratory illness, and whether they had any of 14 specific symptoms characteristic of asthma treatment or any other symptoms associated with an unspecified condition within the previous 14 days. Study participants were followed up on days 7 and 14, at which time they reported any symptoms that had occurred within the past 7 days.

Nares swab specimens for cheap ventolin online canada repeat qPCR assays were also obtained. Participants who had positive qPCR results were placed in isolation and were approached for participation in a related but separate study of infected recruits, which involved more frequent testing during isolation. All recruits who did not participate in the current study were tested for asthma only at the end of the 2-week quarantine, unless clinically indicated (in accordance with the public health procedures of the Marine Corps).

Serum specimens obtained at enrollment were tested for cheap ventolin online canada asthma–specific IgG antibodies with the use of the methods described below and in the Supplementary Appendix. Participants who tested positive on the day of enrollment (day 0) or on day 7 or day 14 were separated from their roommates and were placed in isolation. Otherwise, participants and nonparticipants were not cheap ventolin online canada treated differently.

They followed the same safety protocols, were assigned to rooms and platoons regardless of participation in the study, and received the same formal instruction. Laboratory Methods The qPCR testing of mid-turbinate nares swab specimens for asthma was performed within 48 hours after collection by Lab24 (Boca Raton, FL) with the use of the TaqPath asthma treatment Combo Kit (Thermo Fisher Scientific), which is authorized by the Food and Drug Administration. Specimens obtained from nonparticipants were tested by the Naval Medical Research Center (Silver Spring, MD) cheap ventolin online canada.

Specimens were stored in viral transport medium at 4°C. The presence of IgG antibodies specific to the asthma receptor-binding (spike) domain in serum specimens was evaluated with the use of an enzyme-linked immunosorbent assay, as previously described,10 with some modifications. At least two positive controls, eight negative controls (serum specimens obtained before July 2019), and four blanks (no serum) were cheap ventolin online canada included in every plate.

Serum specimens were first screened at a 1:50 dilution, followed by full dilution series if the specimens were initially found to be positive. Whole-Genome Sequencing and Assembly asthma sequencing was performed with the use of two sequencing protocols (an Illumina sequencing protocol and an Ion Torrent sequencing protocol) to increase the likelihood of obtaining complete genome sequences. A custom reference-based analysis pipeline (https://github.com/mjsull/asthma treatment_pipe) was used to assemble asthma genomes with cheap ventolin online canada the use of data from Illumina, Ion Torrent, or both.11 Phylogenetic Analysis asthma genomes obtained from patients worldwide and associated metadata were downloaded from the Global Initiative on Sharing All Influenza Data EpiCoV database12 on August 11, 2020 (79,840 sequences), and a subset of sequences was selected from this database with the use of the default subsampling scheme of Nextstrain software13 with the aim of maximizing representation of genomes obtained from patients in the United States.

Phylogenetic analyses of the specimens obtained from participants were performed with the v1.0-292-ga9de690 Nextstrain build for asthma genomes with the use of default parameters. Transmission and outbreak events were identified on the basis of clustering of the asthma genomes obtained from study participants within the Nextstrain phylogenetic tree, visualized with TreeTime.14 A comparative analysis of mutation profiles relative to the asthma Wuhan reference genome was performed with the use of Nextclade software, version 0.3.6 (https://clades.nextstrain.org/). Data Analysis The denominator for cheap ventolin online canada calculating the percentage of recruits who had a first positive result for asthma by qPCR assay on each day of testing excluded recruits who had previously tested positive, had dropped out of the study, were administratively separated from the Marine Corps, or had missing data.

The denominator for calculating the cumulative positivity rates included all recruits who had undergone testing at previous time points, including those who were no longer participating in the study. Only descriptive numerical results and percentages are reported, with no formal statistical analysis..

Ventolin hfa ingredients

Human anatomy still has a few ventolin hfa ingredients surprises in store for us. Researchers at the University of Basel have discovered a previously overlooked section of our jaw muscles and described this layer in detail for the first time.The masseter muscle is the most prominent of the jaw muscles ventolin hfa ingredients. If you place your fingers on the back of your cheeks and press your teeth together, you'll feel the muscle tighten. Anatomy textbooks generally describe the masseter as consisting ventolin hfa ingredients of one superficial and one deep part.Now, researchers led by Dr.

Szilvia Mezey from the Department of Biomedicine at the University of Basel and Professor Jens Christoph Türp from the University Center for Dental Medicine Basel (UZB) have described the structure of the masseter muscle as consisting of an additional third, even deeper layer. In the scientific journal Annals of Anatomy, they propose that this layer be given the ventolin hfa ingredients name Musculus masseter pars coronidea -- in other words, the coronoid section of the masseter -- because the newly described layer of muscle is attached to the muscular (or "coronoid") process of the lower jaw.The anatomical study was based on detailed examination of formalin-fixed jaw musculature, computer tomographic scans and the analysis of stained tissue sections from deceased individuals who had donated their bodies to science. This was in addition to MRI data from a living person. As if a new animal species had been ventolin hfa ingredients discovered"This deep section of the masseter muscle is clearly distinguishable from the two other layers in terms of its course and function," explains Mezey.

The arrangement of the muscle fibers, she says, suggests that this layer is involved in the stabilization of the lower jaw. It also appears to be the only part of the masseter that can pull the lower jaw backwards -- ventolin hfa ingredients that is, toward the ear.A look at historical anatomy studies and textbooks reveals that the structure of the masseter muscle has already raised questions in the past. In a previous edition of Gray's Anatomy, from the year 1995, the editors also describe the masseter muscle as having three layers, although the cited studies were based on the jaw musculature of other species and partly contradicted one another.Other individual studies from the early 2000s also reported three layers, but they ventolin hfa ingredients divided the superficial section of the masseter into two layers and agreed with standard works in their description of the deeper section."In view of these contradictory descriptions, we wanted to examine the structure of the masseter muscle again comprehensively," says Türp. "Although it's generally assumed that anatomical research in the last 100 years has left no stone unturned, our finding is a bit like zoologists discovering a new species of vertebrate."

They have long been exploring the nature of consciousness, the question of how and where the brain generates consciousness, and whether animals also have consciousness.

The new concept describes consciousness as a state that is tied to complex cognitive operations -- and not as a passive basic state that automatically prevails when we are awake.Professor Armin ventolin hfa ingredients Zlomuzica from the Behavioral and Clinical Neuroscience research group at RUB and Professor Ekrem Dere, formerly at Université Paris-Sorbonne, now at RUB, describe their theory in the journal Behavioural Brain Research. The printed version will be published on 15 February 2022, the online article has been available since November 2021."The hypotheses underlying our platform theory of consciousness can be tested in experimental studies," as the authors describe one advantage of their concept over alternative models. "Thus, the process of consciousness can be explored in humans and animals or even in the context of artificial intelligence."The platform theory in detailThe complex cognitive operations that, according to platform theory, are associated with consciousness are applied to mental representations ventolin hfa ingredients that are maintained and processed. They can ventolin hfa ingredients include perceptions, emotions, sensations, memories, imaginations and associations.

Conscious cognitive operations are necessary, for example, in situations where learned behaviour or habits are no longer sufficient for coping. People don't ventolin hfa ingredients necessarily need consciousness to drive a car or take a shower. But when something unexpected happens, conscious cognitive actions are required to resolve the situation. They are also necessary to predict future events or ventolin hfa ingredients problems and to develop suitable coping strategies.

Most importantly, conscious cognitive operations are at the basis for adaptive and flexible behaviour that enables humans and animals to adapt to new environmental conditions.According to the new theory, conscious cognitive actions take place on the basis of a so-called online platform, a kind of central executive that controls subordinate platforms. The subordinate platforms can act, for example, as storage media ventolin hfa ingredients for knowledge or activities.Electrical junctions between nerve cells crucialConscious cognitive operations are facilitated by the interaction of different neuronal networks. Armin Zlomuzica and Ekrem Dere consider electrical synapses, also known as gap junctions, to be crucial in this context. These structures enable ventolin hfa ingredients extremely fast transmission of signals between nerve cells.

They work much faster than chemical synapses, where communication between cells takes place through the exchange of neurotransmitters and -modulators.A possible experimentThe ventolin hfa ingredients authors suggest for example the following experiment to test their platform theory. A human, an experimental animal or artificial intelligence is confronted with a novel problem that can only be solved by combining two or more rules learned in a different context. This creative combination of stored information and application to a new problem can only be accomplished using conscious cognitive operations.By administering pharmacological substances that block gap junctions, the researchers would be able to test whether gap junctions do ventolin hfa ingredients indeed play a decisive role in the processes. Gap junction blockers should inhibit performance in the experiment.

However, routine execution of the individual rules, in the contexts in which they were learned, should still be possible."To what extent an artificial intelligence which is capable ventolin hfa ingredients of independently solving a new and complex problem for which it has no predefined solution algorithm can likewise be considered conscious has to be tested," point out the authors. "Several conditions would have to be fulfilled. The first one, ventolin hfa ingredients for example, would be fulfilled, if it successfully proposes a strategy to combat a ventolin by autonomously screening, evaluating, selecting and creatively combining information from the Internet."

About 6 out of every 10 private schools required uniforms in 2011-2012."There hasn't been much research done on the value of school uniforms in the past 20 years or so, especially given how much their use has increased," said Ansari, who is also a faculty associate at Ohio State's Crane Center for Early Childhood Research and Policy.Proponents of school uniforms have argued that, among other things, they promote better attendance and a stronger sense of community, which results in less bullying and fighting. advertisement To test that, the researchers used data from the Early Childhood Longitudinal Study, which followed a nationally representative sample of 6,320 students from kindergarten through the end of fifth grade.Every academic year, teachers rated each student on three dimensions. Internalizing behavior problems (such as anxiety and social withdrawal), externalizing behavior problems (such as aggression or destruction of property) and social skills.Teachers also reported how often each student was absent.Overall, school uniforms had no effect on any of the three dimensions of behavior in any grade, even after taking into account a wide range of other factors that could potentially affect students' behavior.The study did find that low-income students in schools that required uniforms did have slightly better attendance, but that difference amounted to less than one day per year, Ansari said.The researchers also evaluated self-report measures from the same students when they were in fifth grade. Students reported on their sense of school belonging, such as how close they felt to teachers and classmates.

They also reported their experiences of bullying and social anxiety.School uniforms were not linked to any differences in bullying or social anxiety in the children. But those who had to wear uniforms reported lower levels of school belonging than did those who attended schools with no uniform requirements.The data in this study can't explain this finding, Ansari said, but there are some plausible reasons why this might be so."While uniforms are supposed to build a sense of community, they may have the opposite effect," he said."Fashion is one way that students express themselves, and that may be an important part of the school experience. When students can't show their individuality, they may not feel like they belong as much."The results of this study should caution parents, teachers and administrators from assuming that school uniforms have positive effects that they may not have, Ansari said."School uniforms may not be the most effective way to improve student behavior and engagement."The study was supported by the National Institute of Child Health and Human Development.Intensive lifestyle intervention with plenty of exercise helps people with prediabetes improve their blood glucose levels over a period of years and thus delay or even prevent type 2 diabetes. In particular, individuals with prediabetes at highest risk benefited from intensive lifestyle intervention.

This is shown by the evaluation of the Prediabetes Lifestyle Intervention Study (PLIS) of the German Center for Diabetes Research (DZD), which was conducted at 8 sites of the center throughout Germany. The results have now been published in the journal Diabetes.More exercise and healthy eating behavior help many people with prediabetes to normalize their blood glucose levels and avoid developing type 2 diabetes. However, not everyone benefits from a conventional lifestyle intervention (LI). Recent studies show that already in prediabetes, there are different subtypes with different risk profiles.

Researchers at the German Center for Diabetes Research (DZD) have therefore investigated in a multicenter randomized controlled trial whether people with prediabetes and a high risk benefit from an intensification of the intervention and how people with a low risk are affected by a conventional LI compared to no lifestyle changes.The LI lasted 12 months in each case and the follow-up period was a further two years. A total of 1,105 individuals with prediabetes were investigated at various study sites in Germany and assigned to a high-risk or low-risk phenotype based on insulin secretion, insulin sensitivity, and liver fat content. 82% of participants completed the study.A lot helps a lot -- more exercise improves blood glucose and cardiometabolic valuesPeople at high risk -- these individuals produce too little insulin or suffer from fatty liver with insulin resistance -- were randomly assigned to receive conventional LI according to the Diabetes Prevention Program (DPP) or a more intensive intervention with double the amount of required exercise. The results showed that more exercise, i.e.

More intensive LI, helps people at high risk improve their blood glucose and cardiometabolic levels and reduce liver fat content to within the normal range. Conventional LI is less effective.Low-risk participants completed a conventional LI or took part in a control group that received only a one-time brief consultation. "After three years, glucose tolerance was more likely to normalize in participants with conventional LI than in those in the control group," said Professor Hans-Ulrich Häring of the German Center for Diabetes Research and last author of the study. There were hardly any differences in insulin sensitivity and secretion, liver fat content and cardiometabolic risk.Lifestyle intervention based on risk phenotype improves diabetes prevention"Our study results show that an individualized LI based on the risk phenotype is beneficial for diabetes prevention," said study leader Professor Andreas Fritsche from the Institute of Diabetes Research and Metabolic Diseases of Helmholtz Munich at the University of Tübingen (IDM) and the Department of Diabetology, Endocrinology and Nephrology (Director.

Professor Andreas Birkenfeld, MD) at Tübingen University Hospital, summarizing the results. "For successful prevention, we need to identify high-risk patients in the future and focus on providing them with an intensified lifestyle intervention." Story Source.

They say that before developing the tool, their ability to see brain cell activity was like looking up in the night sky with bare eyes and seeing billions of stars.

"It's like we can see and track each of the stars at the same time" now, says Austin Graves, Ph.D., instructor of neuroscience at the Johns Hopkin University School of Medicine.The space between brain cells, or neurons, is incredibly tiny. It's less than a micron -- about a tenth of the width of a human hair. Within these junctions between neurons is a highway of passing molecules and proteins -- mainly sodium and calcium -- transferring from one neuron to the next. advertisement When neurotransmitters pass across a synapse and land on a neuron, they activate an AMPA glutamate receptor -- a protein in the neuron's outer covering.

"These receptors are the functional machinery of language between neurons," says Graves.Huganir and other scientists have shown that synapses and the receptors embedded in them are key locations for learning in the brain. It's where memories are encoded, they say.To study how synapses operate, scientists customarily culture samples of brain cells in the laboratory to screen for increases or decreases in proteins made by the cells. They also examine subsets of neurons in various regions of the brain, but scientists had not previously been able to image synapses in the entire brain on this scale, say the researchers.For the research, the scientists genetically engineered mice by inserting the GRIA1 gene into the DNA, producing a green glowing tag on all AMPA glutamate proteins. When neurons amp up their signaling, they produce more AMPA glutamate proteins, and the green signal gets brighter.

Since AMPA glutamate receptors are very common, the researchers were able to pinpoint nearly all excitatory neurons -- which are more likely to send signals to other neurons instead of block them -- in the mouse brain.Then, the researchers tweaked a whisker on each mouse and used high powered microscopes to track which synapses glowed green and the brightness of the signal. They found about 600,000 glowing synapses and indications that the brightness of the green signal corresponded to the strength of the AMPA glutamate receptor's response. advertisement Huganir says the new system generates mind-boggling amounts of data. So, the researchers worked with computational scientists in the Johns Hopkins Department of Biomedical Engineering to develop artificial intelligence and machine learning techniques to train and validate algorithms that automatically detect all of the glowing synapses and how they change over time with experience and learning.Their current work is a proof-of-principle study that shows the capabilities of this synaptic imaging tool, say the researchers.

Other scientists have asked to use the genetically engineered mice in their studies.The researchers also plan to use the tool to study other mouse behaviors, learning and memory, and to examine how synapses change under certain conditions, such as aging, Alzheimer's Disease and autism.The research was supported by the National Institutes of Health's National Institute on Aging and National Institute of Mental Health (R21 AG063193, R01 MH123212, K99 MH124920) and a Schmidt Science Nascent Innovation Grant.Other scientists who contributed to the work are Richard Roth, Han Tan, Qianwen Zhu, Alexei Bygrave, Elena Lopez-Ortega, Ingie Hong, Alina Spiegel, Richard Johnson, Joshua Vogelstein, Daniel Tward and Michael Miller from Johns Hopkins..

Most importantly, conscious cognitive operations are at the basis for adaptive and flexible behaviour that enables humans and animals to adapt to new environmental conditions.According to the new theory, conscious cognitive actions take place on the basis of a so-called online platform, a kind of central executive that controls subordinate platforms.

The subordinate platforms can act, for example, as storage media for knowledge or activities.Electrical junctions between nerve cells crucialConscious cognitive operations are facilitated by the interaction of different neuronal networks cheap ventolin online canada. Armin Zlomuzica and Ekrem Dere consider electrical synapses, also known as gap junctions, to be crucial in this context. These structures cheap ventolin online canada enable extremely fast transmission of signals between nerve cells. They work much faster than chemical synapses, where communication between cells takes place through cheap ventolin online canada the exchange of neurotransmitters and -modulators.A possible experimentThe authors suggest for example the following experiment to test their platform theory. A human, an experimental animal or artificial intelligence is confronted with a novel problem that can only be solved by combining two or more rules learned in a different context.

This creative combination of stored information and application to a new problem can only be cheap ventolin online canada accomplished using conscious cognitive operations.By administering pharmacological substances that block gap junctions, the researchers would be able to test whether gap junctions do indeed play a decisive role in the processes. Gap junction blockers should inhibit performance in the experiment. However, routine execution of the individual rules, in the contexts in which they were learned, should still be possible."To what extent an artificial intelligence which is capable of independently solving a new and complex problem for which it has no predefined solution algorithm can likewise be considered conscious has to be tested," point out the cheap ventolin online canada authors. "Several conditions would have to be fulfilled. The first one, for example, would be fulfilled, if it successfully proposes a strategy to combat a ventolin by cheap ventolin online canada autonomously screening, evaluating, selecting and creatively combining information from the Internet."

About 6 out of every 10 private schools required uniforms in 2011-2012."There hasn't been much research done on the value of school uniforms in the past 20 years or so, especially given how much their use has increased," said Ansari, who is also a faculty associate at Ohio State's Crane Center for Early Childhood Research and Policy.Proponents of school uniforms have argued that, among other things, they promote better attendance and a stronger sense of community, which results in less bullying and fighting. advertisement To test that, the researchers used data from the Early Childhood Longitudinal Study, which followed a nationally representative sample of 6,320 students from kindergarten through the end of fifth grade.Every academic year, teachers rated each student on three dimensions. Internalizing behavior problems (such as anxiety and social withdrawal), externalizing behavior problems (such as aggression or destruction of property) and social skills.Teachers also reported how often each student was absent.Overall, school uniforms had no effect on any of the three dimensions of behavior in any grade, even after taking into account a wide range of other factors that could potentially affect students' behavior.The study did find that low-income students in schools that required uniforms did have slightly better attendance, but that difference amounted to less than one day per year, Ansari said.The researchers also evaluated self-report measures from the same students when they were in fifth grade. Students reported on their sense of school belonging, such as how close they felt to teachers and classmates. They also reported their experiences of bullying and social anxiety.School uniforms were not linked to any differences in bullying or social anxiety in the children.

But those who had to wear uniforms reported lower levels of school belonging than did those who attended schools with no uniform requirements.The data in this study can't explain this finding, Ansari said, but there are some plausible reasons why this might be so."While uniforms are supposed to build a sense of community, they may have the opposite effect," he said."Fashion is one way that students express themselves, and that may be an important part of the school experience. When students can't show their individuality, they may not feel like they belong as much."The results of this study should caution parents, teachers and administrators from assuming that school uniforms have positive effects that they may not have, Ansari said."School uniforms may not be the most effective way to improve student behavior and engagement."The study was supported by the National Institute of Child Health and Human Development.Intensive lifestyle intervention with plenty of exercise helps people with prediabetes improve their blood glucose levels over a period of years and thus delay or even prevent type 2 diabetes. In particular, individuals with prediabetes at highest risk benefited from intensive lifestyle intervention. This is shown by the evaluation of the Prediabetes Lifestyle Intervention Study (PLIS) of the German Center for Diabetes Research (DZD), which was conducted at 8 sites of the center throughout Germany. The results have now been published in the journal Diabetes.More exercise and healthy eating behavior help many people with prediabetes to normalize their blood glucose levels and avoid developing type 2 diabetes.

However, not everyone benefits from a conventional lifestyle intervention (LI). Recent studies show that already in prediabetes, there are different subtypes with different risk profiles. Researchers at the German Center for Diabetes Research (DZD) have therefore investigated in a multicenter randomized controlled trial whether people with prediabetes and a high risk benefit from an intensification of the intervention and how people with a low risk are affected by a conventional LI compared to no lifestyle changes.The LI lasted 12 months in each case and the follow-up period was a further two years. A total of 1,105 individuals with prediabetes were investigated at various study sites in Germany and assigned to a high-risk or low-risk phenotype based on insulin secretion, insulin sensitivity, and liver fat content. 82% of participants completed the study.A lot helps a lot -- more exercise improves blood glucose and cardiometabolic valuesPeople at high risk -- these individuals produce too little insulin or suffer from fatty liver with insulin resistance -- were randomly assigned to receive conventional LI according to the Diabetes Prevention Program (DPP) or a more intensive intervention with double the amount of required exercise.

The results showed that more exercise, i.e. More intensive LI, helps people at high risk improve their blood glucose and cardiometabolic levels and reduce liver fat content to within the normal range. Conventional LI is less effective.Low-risk participants completed a conventional LI or took part in a control group that received only a one-time brief consultation. "After three years, glucose tolerance was more likely to normalize in participants with conventional LI than in those in the control group," said Professor Hans-Ulrich Häring of the German Center for Diabetes Research and last author of the study. There were hardly any differences in insulin sensitivity and secretion, liver fat content and cardiometabolic risk.Lifestyle intervention based on risk phenotype improves diabetes prevention"Our study results show that an individualized LI based on the risk phenotype is beneficial for diabetes prevention," said study leader Professor Andreas Fritsche from the Institute of Diabetes Research and Metabolic Diseases of Helmholtz Munich at the University of Tübingen (IDM) and the Department of Diabetology, Endocrinology and Nephrology (Director.

Professor Andreas Birkenfeld, MD) at Tübingen University Hospital, summarizing the results. "For successful prevention, we need to identify high-risk patients in the future and focus on providing them with an intensified lifestyle intervention." Story Source.

18 and in its final form Nov. 25 in the journal eLife.The researchers never thought they'd be able to see brain activity on such a massive scale. They say that before developing the tool, their ability to see brain cell activity was like looking up in the night sky with bare eyes and seeing billions of stars. "It's like we can see and track each of the stars at the same time" now, says Austin Graves, Ph.D., instructor of neuroscience at the Johns Hopkin University School of Medicine.The space between brain cells, or neurons, is incredibly tiny. It's less than a micron -- about a tenth of the width of a human hair.

Within these junctions between neurons is a highway of passing molecules and proteins -- mainly sodium and calcium -- transferring from one neuron to the next. advertisement When neurotransmitters pass across a synapse and land on a neuron, they activate an AMPA glutamate receptor -- a protein in the neuron's outer covering. "These receptors are the functional machinery of language between neurons," says Graves.Huganir and other scientists have shown that synapses and the receptors embedded in them are key locations for learning in the brain. It's where memories are encoded, they say.To study how synapses operate, scientists customarily culture samples of brain cells in the laboratory to screen for increases or decreases in proteins made by the cells. They also examine subsets of neurons in various regions of the brain, but scientists had not previously been able to image synapses in the entire brain on this scale, say the researchers.For the research, the scientists genetically engineered mice by inserting the GRIA1 gene into the DNA, producing a green glowing tag on all AMPA glutamate proteins.

When neurons amp up their signaling, they produce more AMPA glutamate proteins, and the green signal gets brighter. Since AMPA glutamate receptors are very common, the researchers were able to pinpoint nearly all excitatory neurons -- which are more likely to send signals to other neurons instead of block them -- in the mouse brain.Then, the researchers tweaked a whisker on each mouse and used high powered microscopes to track which synapses glowed green and the brightness of the signal. They found about 600,000 glowing synapses and indications that the brightness of the green signal corresponded to the strength of the AMPA glutamate receptor's response. advertisement Huganir says the new system generates mind-boggling amounts of data. So, the researchers worked with computational scientists in the Johns Hopkins Department of Biomedical Engineering to develop artificial intelligence and machine learning techniques to train and validate algorithms that automatically detect all of the glowing synapses and how they change over time with experience and learning.Their current work is a proof-of-principle study that shows the capabilities of this synaptic imaging tool, say the researchers.

Other scientists have asked to use the genetically engineered mice in their studies.The researchers also plan to use the tool to study other mouse behaviors, learning and memory, and to examine how synapses change under certain conditions, such as aging, Alzheimer's Disease and autism.The research was supported by the National Institutes of Health's National Institute on Aging and National Institute of Mental Health (R21 AG063193, R01 MH123212, K99 MH124920) and a Schmidt Science Nascent Innovation Grant.Other scientists who contributed to the work are Richard Roth, Han Tan, Qianwen Zhu, Alexei Bygrave, Elena Lopez-Ortega, Ingie Hong, Alina Spiegel, Richard Johnson, Joshua Vogelstein, Daniel Tward and Michael Miller from Johns Hopkins..
