Nell Toussaint is not well. In recent years, she has been diagnosed with uterine fibroids, uncontrolled hypertension, nephrotic syndrome, poorly controlled diabetes, hyperlipidemia, and a pulmonary embolism. She also suffers from decreased mobility, shortness of breath, and‐perhaps not surprisingly, given her other ailments‐anxiety. Toussaint is an indigent undocumented immigrant living in Canada who has been trying to secure medical coverage in the federal courts. In the process, she has sacrificed the medical confidentiality that most of us ordinarily enjoy. (...) Toussaint first came to Canada from Grenada as a visitor in 1999 and remained after the term of her visa expired. At first, she earned enough to sustain a living, but in 2006, her health began to deteriorate, and she was no longer able to work. Although she has received some medical care since then, it has been sporadic, on an emergency basis, and at great expense. When Toussaint applied for medical health coverage under Canada's Interim Medical Health Program, which covers the cost of emergency medical care for legally admitted indigents, her application was rejected. She challenged the decision in federal court on the grounds that her right to life and security of the person under the Canadian Charter had been violated and that the denial of coverage was discriminatory.

In lieu of an abstract, here is a brief excerpt of the content:To Be or Not to Be:Waiving Informed Consent in Emergency ResearchCharles R. McCarthy (bio)The requirements for prior, legally authorized informed consent constitute a necessary condition for recruiting subjects into biomedical or behavioral research. However, informed consent requirements pose a serious problem for most research conducted in emergency care settings. For this reason, the Food and Drug Administration's (FDA) regulations governing investigational devices and the Department of Health and Human (...) Services' (HHS) regulations for the protection of human subjects allow narrow exceptions to the general requirements of informed consent. In a joint effort to clarify the applicability of the current FDA regulations and to better understand the intent of the HHS regulations as they apply to emergency research, the FDA and the National Institutes of Health (NIH) cosponsored a public forum on the ethical conduct of emergency research in January 1995.Although the forum was not designed as a consensus conference and participants vigorously disagreed on some of the details, a broad consensus emerged on several major points: (1) both HHS and FDA regulations should, in the immediate future, be interpreted to allow for randomized clinical trials in emergency situations so long as the subjects are carefully protected; and (2) consideration should be given to producing new, closely harmonized regulations from both agencies that will provide greater clarity concerning what kinds of emergency research may be allowed without obtaining prior informed consent.The FDA-NIH forum in January was occasioned primarily by controversy about the hypothermia research protocol described below, but it is obvious that many other kinds of emergency research also await the outcome of deliberations concerning waiver of informed consent in emergency situations. These include research into the care and treatment of: occlusive stroke; subarachnoid hemorrhage due to intracranial aneurysm; metabolic coma; status epilepticus; cardiac arrest; myocardial infarction; cardiac arrhythmia; hemorrhagic shock; pulmonary embolism; acute asthmatic attack; and poisoning. All of these conditions [End Page 155] are encountered in emergency settings where obtaining informed consent from the patient-subjects to participate in research is seldom possible, and obtaining consent from legally authorized representatives of the subjects is either not feasible, or, if obtained, is of doubtful validity.The Hypothermia Research Case and HHS RegulationsA $7.2 million grant for research on the use of hypothermia in the treatment of severe head trauma, the largest award ever made to the University of Texas Health Sciences Center at Houston, is in danger of expiring before the study is completed. The protocol, which involves the use of cooling blankets to induce hypothermia in patients suffering from severe head injuries, is designed to test the hypothesis that: "Early lowering of the body temperature of patients suffering from severe head trauma to approximately 91 degrees Fahrenheit will slow patients' metabolism and will/will not, as a consequence, reduce the rates of both morbidity and mortality in these patients." The protocol was approved by seven Institutional Review Boards (IRBs), each of which waived the requirement to obtain informed consent from research subjects in accordance with Sec. 46. 116(d) of the HHS Regulations for the Protection of Human Subjects.1However, NIH's Office for Protection from Research Risks (OPRR), which is responsible for assuring compliance with the HHS regulations, has taken a controversial regulatory position by requiring informed consent from a legally authorized representative of each subject to be entered in the hypothermia trial. Because the obtaining of surrogate consent has proved to be very difficult, OPRR's position has slowed the research to a point where it may have to be terminated.At issue in the controversy is a fundamental question of ethics and public policy. Is it ever permissible to involve incompetent subjects in research without either their consent, or the consent of their legally authorized representatives? Pertinent HHS regulations for the protection of human subjects seem to answer the question affirmatively by allowing local IRBs to waive some or all of the elements of informed consent under carefully limited circumstances (45 CFR 46 116(d)). Nevertheless, OPRR has signalled the research community that use of the informed consent waiver provision for the Houston hypothermia study is not permitted under the regulations. OPRR judged that the risks... (shrink)

Paula Modersohn-Becker, widely considered to have been one of the most important independent Expressionist painters of the early twentieth century, was thirty-one years old when she gave birth to her first child. Following the then-common practice of putting women to bed rest for two-four weeks after delivery, she died of massive pulmonary embolism when she was first allowed to stand, eighteen days after giving birth. Paula had foreseen her death at a young age and was apprehensive about her (...) pregnancy, yet she painted herself as pregnant in her best known self-portrait, thus underlining the importance of the pregnancy in her life. In the light of knowledge available at the time, the authors present a brief discussion of the life and death of Paula Modersohn-Becker as a reflection on the potential dangers of blindly following conventional wisdom in the medical profession.

Background Cancer patients are at risk of developing blood clots in their veins - venous thromboembolism - which often takes the form of a pulmonary embolism or deep vein thrombosis. The risk increases with advanced disease. Evidence based treatment is low molecular weight heparin by daily subcutaneous injection. The aim of this research is to explore the barriers for doctors in the UK when diagnosing and treating advanced cancer patients with VTE. Method Qualitative, in-depth interview study with 45 (...) doctors. Doctors were from three specialties: oncology, palliative medicine and general practice, with a mixture of senior and junior staff. Framework analysis was used. Results Doctors opinions as to whether LMWH treatment was ethically appropriate for patients who were symptomatic from VTE but at end of life existed on a shifting continuum, largely influenced by patient prognosis. A lack of immediate benefit coupled with the discomfort of a daily injection had influenced some doctors not to prescribe LMWH. The point at which LMWH injections should be stopped in patients at the end of life was ambiguous_._ Some perceived ‘overcaution’ in their own and other clinicians’ treatment of patients_._ Viewpoints were divergent on whether dying of a PE was considered a “good way to go”. The interventionalism and ethos of palliative medicine was discussed. Conclusions Decisions are difficult for doctors to make regarding LMWH treatment for advanced cancer patients with VTE. Treatment for this patient group is bounded to the doctors own moral and ethical frameworks. (shrink)

A thirty-year-old single mother with recurrent, metastatic, treatment-refractory cancer presents to the emergency room with severe difficulty breathing due to an obstructive tumor in her neck, compounded by progressive disease in her lungs and a new pulmonary embolism. She cannot be safely intubated and would require an emergent awake tracheotomy. Even if the airway can be successfully secured surgically, the likelihood that she will be able to be weaned from mechanical ventilation is very low. The surgeon, a young (...) mother too, appreciates the patient's desire for more time with her toddler. But the surgeon knows the significant risk of surgery, the massive responsibility she would accept in trying to get the patient through it, and the emotional toll of an intraoperative death on surgical staff. And she can imagine the second-guessing that will come during the inevitable morbidity and mortality conference if the patient should die in the perioperative window. Yet the surgeon does not want to take the “easy” way out; after all, critically ill patients undergo aggressive resuscitation all the time. What should she do? (shrink)

More than 15 million people have been affected by coronavirus disease 2019 (COVID‐19) and it has caused 640 016 deaths as of July 26, 2020. Currently, no effective treatment option is available for COVID‐19 patients. Though many drugs have been proposed, none of them has shown particular efficacy in clinical trials. In this article, the relationship between the Adrenergic system and the renin‐angiotensin‐aldosterone system (RAAS) is focused in COVID‐19 and a vicious circle consisting of the Adrenergic system‐RAAS‐Angiotensin converting enzyme 2 (...) (ACE2)‐severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) (which is referred to as the “ARAS loop”) is proposed. Hyperactivation of the ARAS loop may be the underlying pathophysiological mechanism in COVID‐19, and beta‐adrenergic blockers are proposed as a potential treatment option. Beta‐adrenergic blockers may decrease the SARS‐CoV‐2 cellular entry by decreasing ACE2 receptors expression and cluster of differentiation 147 (CD147) in various cells in the body. Beta‐adrenergic blockers may decrease the morbidity and mortality in COVID‐19 patients by preventing or reducing acute respiratory distress syndrome (ARDS) and other complications. Retrospective and prospective clinical trials should be conducted to check the validity of the hypothesis. Also see the video abstract here https://youtu.be/uLoy7do5ROo. (shrink)

Objective: Pulmonary complications could badly affect the recovery of neurological function and neurological prognosis of neurological critically ill patients. This study evaluated the effect of high-flow nasal cannula therapy on decreasing pulmonary complications in neurologically critically ill patients.Patients and Methods: The patients admitted to the intensive care unit with serious neurological disease and receiving oxygen therapy were retrospectively reviewed. Patients were divided into the HFNC group and the conventional oxygen therapy group. We analyzed the data within these two (...) groups, including patients’ baseline data, short-term outcomes of respiratory complications, general outcomes including hospital stay, ICU stay and mortality, and neurological functions. To analyze the relevant factors, we performed multivariable logistic regression analysis.Results: A total of 283 patients met the criteria, including 164 cases in the HFNC group and 119 cases in the COT group. The HFNC group had remarkably less mechanical ventilation requirement with lower phlegm viscosity. Even more, ICU stay and total hospital stay were significantly shortened in the HNFC group.Conclusion: HFNC decreased pulmonary complications in neurologically critically ill patients and improved recovery of neurological function and neurological prognosis.

The application of in vivo genetic lineage tracing has advanced our understanding of cellular mechanisms for tissue renewal in organs with slow turnover, like the lung. These studies have identified an adult stem cell with very different properties than classically understood ones that maintain continuously cycling tissues such as the intestine. A portrait has emerged of an ensemble of cellular programs that replenish the cells that line the gas exchange (alveolar) surface, enabling a response tailored to the extent of cell (...) loss. A capacity for differentiated cells to undergo direct lineage transitions allows for local restoration of proper cell balance at sites of injury. We present these recent findings as a paradigm for how a relatively quiescent tissue compartment can maintain homeostasis throughout a lifetime punctuated by injuries ranging from mild to life‐threatening, and discuss how dysfunction or insufficiency of alveolar repair programs produce serious health consequences like cancer and fibrosis.

A theory of embolism based on an optimization model of blood flow is proposed and used to explain the topographic distribution of emboli in arterial trees.

Pulmonary rehabilitation has demonstrated patients’ physiological and psychosocial improvements, symptoms reduction and health-economic benefits whilst enhances the ability of the whole family to adjust to illness. However, PR remains highly inaccessible due to lack of awareness of its benefits, poor referral and availability mostly in hospitals. Novel models of PR delivery are needed to enhance its implementation while maintaining cost-efficiency. We aim to implement an innovative community-based PR programme and assess its cost-benefit. A 12-week community-based PR will be implemented (...) in primary healthcare centres where programmes are not available. Healthcare professionals will be trained. 73 patients with CRD and their caregivers will compose the experimental group. The control group will include dyads age- and disease-matched willing to collaborate in data collection but not in PR. Patients/family-centred outcomes will be dyspnoea, fatigue, cough and sputum, impact of the disease, emotional state, number of exacerbations, healthcare utilisation, health-related quality of life and family adaptability/cohesion. Other clinical outcomes will be peripheral and respiratory muscle strength, muscle thickness and cross sectional area, exercise capacity, balance and physical activity. Data will be collected at baseline, at 12 weeks, at 3- and 6-months post-PR. Changes in the outcome measures will be compared between groups, after multivariate adjustment for possible confounders, and effect sizes will be calculated. A cost-benefit analysis will be conducted. This study will enhance patients access to PR, by training healthcare professionals in the local primary healthcare centres to conduct such programmes and actively involving caregivers. The cost-benefit analysis of this intervention will provide an evidence-based insight into the economic benefit of community-based PR in chronic respiratory diseases. The trial was registered in the ClinicalTrials. gov U.S. National Library of Medicine, on 10th January, 2019. (shrink)

There are two competing accounts for a theory for human action proposed by Catholic theologians working within the received moral tradition today: a hylomorphic account and an intentional account.

HLDING A‐G and HEGGDAL K. Nursing Inquiry 2012; 19: 345–356 Patients’ experiences of health transitions in pulmonary rehabilitationPeople who live with chronic obstructive pulmonary disease (COPD) experience major changes in health. Coping with the illness and caring for themselves places extensive demands on them. Thus, pulmonary rehabilitation (PR) is recommended as a means to facilitate healthy transitions in everyday life with COPD. This study explores the experience of patients with COPD in terms of their transitions in health (...) during and after PR. The research was inspired by interpretive phenomenology. Thirty‐three individual qualitative interviews were conducted with eighteen patients recruited from Norwegian PR units. A thematic analysis of the interviews was performed. The interviewees described participation in PR as a time of increasing awareness of opportunities for health and well‐being with strengthened hope. The year following PR was dominated by their ongoing challenge to acknowledge limitations and explore opportunities in everyday life. Continuation of healthy transitions was facilitated by peer and professional support. The study highlights the personal resources that patients with COPD have access to in order to promote their own health. The study also highlights their vulnerability during illness and rehabilitation. The findings critique time‐limited PR and support the current trends towards patient‐centred rehabilitation efforts that incorporate user involvement and self‐management education. (shrink)

Patients with chronic obstructive pulmonary disease are characterized by attenuated pulmonary function and are frequently reported with cognitive impairments, especially memory impairments. The mechanism underlying the memory impairments still remains unclear. We applied resting-state functional magnetic resonance imaging to compare the brain local activities with static and dynamic amplitude of low-frequency fluctuations among patients with COPD and healthy controls. Compared with HC, COPD patients exhibited decreased sALFF in the right basal ganglia and increased dALFF in the bilateral parahippocampal/hippocampal (...) gyrus. The reduced the left basal ganglia was associated with lower oxygen partial pressure. Besides, the increased dALFF in the left hippocampal/parahippocampal cortex was associated with poor semantic-memory performance and the increased dALFF in the left hippocampal/parahippocampal cortex was associated the forced vital capacity. The present study revealed the abnormal static and dynamic local-neural activities in the basal ganglia and parahippocampal/hippocampal cortex in COPD patient and its relationship with poor lung function and semantic-memory impairments.

BackgroundCommonly applied measures of symptoms of anxiety are not sensitive to disease-specific anxiety in patients with chronic obstructive pulmonary disease. There is a need for validated instruments measuring COPD-specific anxiety. Therefore, we translated the COPD-Anxiety Questionnaire into Danish and performed an initial validation of the psychometric properties in a sample of patients with COPD.Materials and MethodsTranslation procedures followed the World Health Organization guidelines. Participants with COPD completed questionnaires measuring COPD-specific anxiety, general psychological distress as well as variables related to (...) COPD, quality of life, and socio-demography.ResultsA total of 260 patients with COPD completed questionnaires. The Danish version of CAF-R-DK demonstrated acceptable Cronbach’s α values that were comparable with those of the original CAF. As expected, the CAF-R-DK showed positive correlations with convergent constructs and negative correlations with discriminant constructs. However, the results for specific subdomains of the CAF-R-DK indicated inconsistency in the underlying concept of disease-specific anxiety, which was also suggested based on the subsequent confirmatory and exploratory factor analyzes.ConclusionThe CAF could serve as an important supplement to generic psychological distress screening of patients with COPD in somatic health care settings, and the questionnaire is now available in Danish. Translation into other languages is needed with the purpose of obtaining data for further testing the psychometric properties of the questionnaire. (shrink)

Transfer learning can improve the robustness of deep learning in the case of small samples. However, when the semantic difference between the source domain data and the target domain data is large, transfer learning easily introduces redundant features and leads to negative transfer. According the mechanism of the human brain focusing on effective features while ignoring redundant features in recognition tasks, a brain-like classification method based on adaptive feature matching dual-source domain heterogeneous transfer learning is proposed for the preoperative aided (...) diagnosis of lung granuloma and lung adenocarcinoma for patients with solitary pulmonary solid nodule in the case of small samples. The method includes two parts: (1) feature extraction and (2) feature classification. In the feature extraction part, first, By simulating the feature selection mechanism of the human brain in the process of drawing inferences about other cases from one instance, an adaptive selected-based dual-source domain feature matching network is proposed to determine the matching weight of each pair of feature maps and each pair of convolution layers between the two source networks and the target network, respectively. These two weights can, respectively, adaptive select the features in the source network that are conducive to the learning of the target task, and the destination of feature transfer to improve the robustness of the target network. Meanwhile, a target network based on diverse branch block is proposed, which made the target network have different receptive fields and complex paths to further improve the feature expression ability of the target network. Second, the convolution kernel of the target network is used as the feature extractor to extract features. In the feature classification part, an ensemble classifier based on sparse Bayesian extreme learning machine is proposed that can automatically decide how to combine the output of base classifiers to improve the classification performance. Finally, the experimental results (the AUCs were 0.9542 and 0.9356, respectively) on the data of two center data show that this method can provide a better diagnostic reference for doctors. (shrink)

Background:Cardio-pulmonary resuscitation is the default procedure during cardio-pulmonary arrest. If a patient does not want cardio-pulmonary resuscitation, then a do not attempt resuscitation order must be documented. Often, this order is not given; even if thought to be appropriate. This situation can lead to a slow code, defined as an ineffective resuscitation, where all resuscitation procedures are not performed or done slowly.Research objectives:To describe the perceptions of nurses working on internal medicine wards of slow codes, including the (...) factors associated with its implementation.Research design:This was a cross-sectional, descriptive study. Participants completed a personal characteristics questionnaire and the Perceptions and Factors of Slow Codes questionnaire designed for this study.Participants and research context:The sample was a convenience sample of nurses working on internal medicine wards in two Israeli hospitals.Ethical considerations:The study received ethical approval from both institutions, where data were collected and stored according to institutional policy.Findings:Most reported that resuscitations were conducted according to protocol. Some took their time calling the code, or waited by the bedside and did not perform cardio-pulmonary resuscitation. Factors most associated with slow codes were poor patient prognosis and a low chance of patient survival. Two-thirds reported that slow codes were done on their unit and the majority perceived slow codes as ethical.Discussion:This study confirms that slow codes are part of medical care on internal medicine wards, where most nurses perceive them as an ethical alternative. These perceptions are in contrast to most legal and ethical opinions expressed in the literature.Conclusion:Nurses should be educated about the legal and ethical implications of slow codes, and qualitative and quantitative studies should be conducted that further investigate its implementation.

Background Decisions regarding Cardio-Pulmonary Resuscitation (CPR) and Do Not Attempt Resuscitation (DNAR) orders remain demanding, as does including patients in the process. Objectives To explore physicians’ justification for CPR/DNAR orders and decisions regarding patient inclusion, as well as their reports of how they initiated discussions with patients. Methods We administered a face-to-face survey to residents in charge of 206 patients including DNAR and CPR orders, with or without patient inclusion. Results Justifications were provided for 59% of DNAR orders and (...) included severe comorbidity, patients and families’ resuscitation preferences, patients’ age, or poor prognosis or quality of life. Reasons to include patients in CPR/DNAR decisions were provided in 96% and 84% of cases, and were based on respect for autonomy, clinical assessment of the situation as not too severe, and the view that such inclusion was required. Reasons for not including patients were offered in 84% of cases for CPR and in 70% for DNAR. They included absent decision-making capacity, a clinical situation viewed as good (CPR) or offering little hope of recovery (DNAR), barriers to communication, or concern that discussions could be emotionally difficult or superfluous. Decisions made earlier in the patient's management were infrequently viewed as requiring revision. Residents reported a variety of introductions to discussions with patients. Conclusions These results provide better understanding of reasons for CPR/DNAR decisions, reasons for patient inclusion or lack thereof, and ways in which such inclusion is initiated. They also point to potential side-effects of implementing CPR/DNAR recommendations without in-depth and practical training. This should be part of a regular audit and follow-up process for such recommendations. (shrink)

Chronic obstructive pulmonary disease (COPD) is one of the most deadly and costly chronic diseases in the world characterized by many breathing problems. The management of COPD and the prevention of exacerbations are a priority goals to improve the quality of life in patients affected by this illness. In addition, it is also crucial to improve the patients’ adherence to care which, in turn, depends on their knowledge and understanding of some factors such as the prescribed medical treatment, changes (...) in dailylife, and the process of breathing. In turn, the adherence to care leads to greater autonomy for the patient who is thus able to better manage his illness. Here we presented the application of the Model IARA in patients affected by COPD in order to achieve their autonomy in illness management which, in turn, leads to a better quality of life. IARA is an intervention program which improve the awareness and knowledge of patients with respect to both the disease and symptoms through health education. Moreover, through IARA the patients are encouraged to become more actively involved in COPD care process, also regarding drug therapy adherence. Using St. George's Respiratory Questionnaire combined with qualitative analysis, we demonstrated that IARA could be considered a useful approach in COPD management. (shrink)

Health is already being harmed by global temperature increases and the destruction of the natural world, a state of affairs health professionals have been bringing attention to for decades.1 The science is unequivocal; a global increase of 1.5°C above the preindustrial average and the continued loss of biodiversity risk catastrophic harm to health that will be impossible to reverse.2 3 Despite the world’s necessary preoccupation with COVID-19, we cannot wait for the pandemic to pass to rapidly reduce emissions. Reflecting the severity of the moment, this editorial appears in health journals across the world. We are united in recognising that only fundamental and equitable changes to societies will reverse our current trajectory. The risks to health of increases above 1.5°C are now well established.2 Indeed, no temperature rise is ‘safe’. In the past 20 years, heat-related mortality among people aged over 65 has increased by more than 50%.4 Higher temperatures have brought increased dehydration and renal function loss, dermatological malignancies, tropical infections, adverse mental health outcomes, pregnancy complications, allergies, and cardiovascular and pulmonary morbidity and mortality.5 6 Harms disproportionately affect the most vulnerable, including children, older populations, ethnic minorities, poorer communities and those with underlying health problems.2 4 Global heating is also contributing to the decline in ….

Our hospital routine requires that all new admissions must be asked about their code status. It is not uncommon for an otherwise healthy patient to request that a do-not-resuscitate order be placed in their chart. Presumably, these patients who wish to have a DNR order are acting on the belief that should an unforeseen, irreversible condition occur that leads to a cardiac arrest, they would not want to undergo resuscitation. Tragically, we have witnessed several instances in which potentially life-saving interventions (...) were withheld in viable patients in non-arrest settings for reversible conditions because the patients had a DNR order in the chart. Unfortunately, this happens when the treating physicians are not aware of the limited scope of a DNR order and instead use the order as a blanket prohibition against all components of resuscitation. This communication failure is due to misconceptions that patients and their physicians have with regard to such orders. The medical community is well overdue to improve the end-of-life decisions offered to patients beyond relying on the outdated term DNR.LIMITATIONS OF DNR ORDERSDespite the major advances in critical care medicine in the past few decades, doctors have not substantially improved their ability to address end-of-life decisions any better than by using the all-encompassing term DNR. Currently, the term is generally accepted as an order to prohibit the use of interventions to reverse a cardiac or pulmonary arrest.1 2 What is frequently forgotten with the DNR order is that ….
