When families cannot "let go": ethical decision-making at the bedside.

Shared decision-making at the bedside is now a regular feature of medical practice. When disagreements arise between a patient and family members caregivers sometimes find themselves caught in a complex tangle of human relationships that strains monochrome ethical thinking. The patient''s expressed wishes are often compromised for the sake of the family''s needs. Conversely, a unilateral appeal for patient autonomy may prove insensitive to the hurt and the needs of the family. We describe a relatively unsuccessful attempt by a patient''s caregivers to buy time to maximize the interests of the patient and her family and discuss the way in which the family dynamics militated against the rather obvious solution of promoting the patient''s right to refuse treatment. The purpose of this article is not to evoke sympathy for health care professionals in dealing with such conflicts but rather to heighten awareness of the issues at stake and to stimulate thinking about ways and means to bring about a more favourable outcome than the one described here.     

Withholding and withdrawing life sustaining treatment from elderly people: towards formal guidelines.

Clinicians often decide either to withhold or to withdraw lifesaving treatment in elderly patients. Considerable disagreement exists about the circumstances in which such actions can be defended. Debates about the scarcity of resources in the NHS add urgency to the need to resolve this disagreement. Competent elderly patients have a legal and moral right to decide whether to receive life sustaining treatment. Such treatment should not be withheld or withdrawn on the basis of a patient''s age alone. Principles for making decisions about life sustaining treatment in incompetent elderly patients can be defended and should exist as written guidelines.     

Selection of Populations: An Overview and Some Recent Results

In practice the problem of comparing several treatments can often be formulated as which treatment can be considered best. Selection procedures have been designed specifically to answer questions like this one. In many situations selection procedures are more realistic than the usual testing procedures. In this paper an introduction and an overview of selection of populations will be given with special reference to Normal, Binomial, Poisson and Multinomial populations. In the field of agricultural applications these distributions play an important role. Bechhofer's and Gupta's approach are presented side by side for a number of problems. After that the relatively new procedures of Somerville are discussed. Finally, some recent results are presented.     

Needs for care from a demand led community psychiatric service: a study of patients with major mental illness.

OBJECTIVE--To measure needs for care of patients aged 18-65 years with major mental illness. DESIGN. Identification of everyone in one area seen by a health professional within the previous five years because of a psychotic disorder. Interview of a one in three sample of patients and their main carers with the cardinal needs schedule. SETTING--Hamilton, a socially deprived district of Scotland. SUBJECTS--71 subjects were interviewed from the original sample of 263 patients. MAIN OUTCOME MEASURES--"Cardinal problems" in seven clinical and eight social areas of functioning; these are defined as problems requiring action. "Needs"-cardinal problems for which suitable interventions exist but have not been tried recently. RESULTS--High levels of morbidity were found. 30 interviewed patients (42%; 95% confidence interval 31% to 54%) had one or more clinical needs. 35 (49%; 38% to 61%) had one or more social needs. Skills to deal with all but seven needs in the sample were available at the time of investigation. Patients not being seen by the community mental health team were similar in severity and levels of need to those who were on the community team''s caseload. Care was unequivocally and severely inadequate for four patients. Shortcomings in service delivery usually arose from failure to monitor some patients at home. Problems were not due to shortage of acute psychiatric beds nor the absence of an elaborate assertive community care team. CONCLUSIONS--Systematic assessment of needs with research instruments can give valuable insights into the successes and failures of community care of people with major mental illness. Most needs could be dealt with in these patients but in our area (and probably most other parts of the United Kingdom) this would entail diversion of resources from people with less severe disorders.     

Which physicians make home visits and why? A survey

BACKGROUND: Recent changes in the North American health care system and certain demographic factors have led to increases in home care services. Little information is available to identify the strategies that could facilitate this transformation in medical practice and ensure that such changes respond adequately to patients'' needs. As a first step, the authors attempted to identify the major factors influencing physicians'' home care practices in the Quebec City area. METHODS: A self-administered questionnaire was sent by mail to all 696 general practitioners working in the Quebec City area. The questionnaire was intended to gather information on physicians'' personal and professional characteristics, as well as their home care practice (practice volume, characteristics of both clients and home visits, and methods of patient assessment and follow-up). RESULTS: A total of 487 physicians (70.0%) responded to the questionnaire, 283 (58.1%) of whom reported making home visits. Of these, 119 (42.0%) made fewer than 5 home visits per week, and 88 (31.1%) dedicated 3 hours or less each week to this activity. Physicians in private practice made more home visits than their counterparts in family medicine units and CLSCs (centres locaux des services communautaires [community centres for social and health services]) (mean 11.5 v. 5.8 visits per week), although the 2 groups reported spending about the same amount of time on this type of work (mean 5.6 v. 5.0 hours per week). The proportion of visits to patients in residential facilities or other private residences was greater for private practitioners than for physicians from family medicine units and CLSCs (29.7% v. 18.9% of visits), as were the proportions of visits made at the patient''s request (28.0% v. 14.2% of visits) and resulting from an acute condition (21.4% v. 16.0% of visits). The proportion of physicians making home visits at the request of a CLSC was greater for those in family medicine units and CLSCs than for those in private practice (44.0% v. 11.3% of physicians), as was the proportion of physicians making home visits at the request of a colleague (18.0% v. 4.5%) or at the request of hospitals (30.0% v. 6.8%). Physicians in family medicine units and CLSCs did more follow-ups at a frequency of less than once per month than private practitioners (50.9% v. 37.1% of patients), and they treated a greater proportion of patients with cognitive disorders (17.2% v. 12.6% of patients) and palliative care needs (13.7% v. 8.6% of patients). Private practitioners made less use of CLSC resources to assess home patients or follow them. Male private practitioners made more home visits than their female counterparts (mean 12.8 v. 8.3 per week), although they spent an almost equal amount of time on this activity (mean 5.7 v. 5.2 hours per week). INTERPRETATION: These results suggest that practice patterns for home care vary according to the physician''s practice setting and sex. Because of foreseeable increases in the numbers of patients needing home care, further research is required to evaluate how physicians'' practices can be adapted to patients'' needs in this area.     

Osteoporosis in neurodegeneration

Osteoporosis affects bone microarchitecture and reduces bone mass. There are more than 200 million people with osteoporosis worldwide, and the prevalence is slowly increasing. The highest prevalences are found in Scandinavia and USA, also slowly increasing. A parallel increase in neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, Amyotrophic lateral sclerosis, and multiple sclerosis has been noted since the middle of this century. Osteoporosis is more common in patients with each of these neurodegenerative conditions than in the general population. Several metals with neurotoxic properties accumulate in bone and can substitute for calcium in hydroxyapatite, the main mineral component of bone. Especially cadmium, but also lead, aluminum and arsenic affect bone mineral density negatively. Metals with neurotoxic properties have also been found in brain and cerebrospinal fluid from patients with Alzheimer's disease, Parkinson's disease, Amyotrophic lateral sclerosis, and multiple sclerosis, and markers for neurodegeneration such as amyloid beta peptide and amyloid precursor protein have been detected in bone tissue from patients with osteoporosis. A common mechanism contributing to the pathogenesis of both neurodegeneration and osteoporosis can be suspected. The hypothesis that neurodegenerative disorders are associated with osteoporosis is presented and discussed.     

Legal obligation of physicians to disclose information to patients.

Obtaining a patient''s consent is a routine daily process for physicians, although many are unaware of the scope of this legal obligation. In 1980 the Supreme Court of Canada changed the law relating to informed consent; promotion of patient autonomy shifted the focus from a standard of professional disclosure to one of a "reasonable patient." Physicians have a legal obligation to disclose to patients specific information, the scope of which is determined by a court on the basis of a reasonable patient''s expectation and the circumstances of the case. This gives rise to many controversies in the practice of clinical medicine. It is difficult for physicians to know which treatment risks require disclosure, since this is decided by a court in a retrospective analysis of the evidence. Will the court recognize exceptions to the duty of disclosing information? If several health care professionals are involved in a patient''s care who has the duty to disclose information? Can this duty be delegated? This paper provides physicians with guidelines that are consistent with the promotion of patient autonomy and comply with the doctrine of informed consent. In addition, it suggests ways of improving awareness of the doctrine and procedures to ease its application.     

Management of the rape victim.

A woman''s response to rape can be divided into three phases: an acute reaction, an intermediate stage and a period of resolution. Proper management of the physical and emotional problems of each phase, ideally by the woman''s family doctor or gynecologist, may prevent future problems. Treatment during the first phase includes responding to the emotional needs of the patient as well as doing a pelvic and general physical examination to detect any injuries; information for possible legal procedures may be obtained quickly and efficiently. Follow-up particularly psychological, is important in the second and third phases.     

Psychopathology in adolescent children of physicians.

The clinical records of 27 adolescent children of physicians who were treated in a psychiatric unit for adolescents were studied. Most of the children had been referred by their physician fathers for evaluation of conduct or mood disorders. These referrals were often the focus of family distress. There appeared to be no typical syndrome presented by physicians'' children. Those treating such patients should be especially sensitive to the possibility that parental denial will increase the patient''s resistance to therapy. Family therapy, an effective treatment for psychologic problems in adolescents, is often avoided by physicians.     

Women's understanding of abnormal cervical smear test results: a qualitative interview study.

OBJECTIVE: To describe how women interpret their experiences of diagnosis and treatment of a cervical abnormality and how healthcare services for such women can be improved. DESIGN: Qualitative study using detailed individual interviews. SETTING: Australian gynaecology clinics. SUBJECTS: 29 Women who had a cervical cytological abnormality and who attended a gynaecologist. MAIN OUTCOME MEASURES: Women''s views on their diagnosis and their information needs. RESULTS: Most women wanted to participate in decisions about their care but found it difficult to get the information they required from doctors because they were confused by what their doctors told them and felt unable to ask questions in the consultation. Medical terms such as wart virus and precancer were difficult to understand. Not being able to see their cervix also made it hard for women to understand what their abnormality meant and what treatment entailed. Most women tried to make sense of their abnormality in the context of their everyday lives. For some women their gynaecological care was not consistent with the way they understood their abnormality. CONCLUSIONS: The inherent power structure of medical practice combined with time pressures often make it difficult for doctors to give the detailed information and reassurance patients need when a diagnosis is distressing or when investigation and treatment are strange and upsetting.     

How Are the Interests of Incapacitated Research Participants Protected through Legislation? An Italian Study on Legal Agency for Dementia Patients

Background

Patients with dementia may have limited capacity to give informed consent to participate in clinical research. One possible way to safeguard the patients'' interests in research is the involvement of a proxy in the recruitment process. In Italy, the system of proxy is determined by the courts. In this study we evaluate the timing for appointment of a legal proxy in Italy and identify predictive variables of appointment.

Methodology/Principal Findings

Subjects were recruited among the outpatients seeking medical advice for cognitive complaints at the Centre for Research and Treatment of Cognitive Dysfunctions, University of Milan, “Luigi Sacco” Hospital.The Centre was participating to the AdCare Study, a no-profit randomised clinical trial coordinated by the Italian National Institute of Health. The requirement that informed consent be given by a legal representative dramatically slowed down the recruitment process in AdCare, which was prematurely interrupted. The Centre for Research and Treatment of Cognitive Dysfunctions collected data on the timing required to appoint the legal representatives. Patients diagnosed with dementia and their caregivers were provided information on the Italian law on legal agency (law 6/2004). At each scheduled check-up the caregiver was asked whether she/he had applied to appoint a legal proxy for the patient and the time interval between the presentation of the law, the registration of the application at the law court chancellery and the sentence of appointment was registered. The study involved 169 demented patients. Seventy-eight patients (46.2%) applied to appoint a legal proxy. These subjects were usually younger, had been suffering from dementia for a longer time, had less than two children and made more use of memantine. The mean interval time between the presentation of the law and the patients'' application to the law court chancellery was two months. The mean interval time between the patient''s application to the law court chancellery and the sentence of appointment was four months.

Conclusions/Significance

In Italy the requirement that legal representatives be appointed by the courts slows down subjects'' participation in research. Other procedures for legal agency of the incapacitated patients may be adopted, taking as examples other EU countries'' systems.     

Molecular mechanisms of developmental pathways in neurological disorders: a pharmacological and therapeutic review

Developmental signalling pathways such as Wnt/β-catenin, Notch and Sonic hedgehog play a central role in nearly all the stages of neuronal development. The term ‘embryonic’ might appear to be a misnomer to several people because these pathways are functional during the early stages of embryonic development and adulthood, albeit to a certain degree. Therefore, any aberration in these pathways or their associated components may contribute towards a detrimental outcome in the form of neurological disorders such as Alzheimer''s disease, Parkinson''s disease, amyotrophic lateral sclerosis and stroke. In the last decade, researchers have extensively studied these pathways to decipher disease-related interactions, which can be used as therapeutic targets to improve outcomes in patients with neurological abnormalities. However, a lot remains to be understood in this domain. Nevertheless, there is strong evidence supporting the fact that embryonic signalling is indeed a crucial mechanism as is manifested by its role in driving memory loss, motor impairments and many other processes after brain trauma. In this review, we explore the key roles of three embryonic pathways in modulating a range of homeostatic processes such as maintaining blood–brain barrier integrity, mitochondrial dynamics and neuroinflammation. In addition, we extensively investigated the effect of these pathways in driving the pathophysiology of a range of disorders such as Alzheimer''s, Parkinson''s and diabetic neuropathy. The concluding section of the review is dedicated to neurotherapeutics, wherein we identify and list a range of biological molecules and compounds that have shown enormous potential in improving prognosis in patients with these disorders.     

The ethnomedicinal evidences pertaining to traditional medicinal herbs used in the treatment of respiratory illnesses and disorders in Saudi Arabia: A review

Due to their prevalence, respiratory diseases have attained great attention from the historical time. Furthermore, it has been explored in a new dimension due to recent viral outbreaks such as COVID-19. Even though modern medicine treats the majority of respiratory ailments, it is reported that the majority of people (≥80 %) who suffer from respiratory disorders do not take medication for their conditions, and a considerable number of people still believe in and use herbal medicines. Herbal therapies have been utilized all over the world for thousands of years. Traditional herbal treatment has long been seen as a valuable practice in Saudi Arabia, long before modern medicine. Due to its location in the desert and humid climate, Saudi Arabia suffers from a high rate of respiratory illnesses caused by dust, pollens, and viruses. Several published literature have employed different plants and plant products for respiratory problems, but there has yet to be a single, complete study centered on Saudi Arabia. In this review, 41 plants were identified, which has complete details regarding their usage in traditional practice for respiratory disorders. A thorough investigation was conducted and the results were detailed.     

Professional psychological support and psychotherapy methods for oncology patients. Basic concepts and issues

Background

The essence of psychological support provided to oncology patients is to adjust its methods to the needs and expectations arising from the distressful experience of cancer and its treatment.

Aim

The aim of this study is to present methods of professional psychological support to be used in work with oncology patients during the treatment and follow-up stages.

Materials and methods

The article is a review of psychological and psychotherapy methods most often applied to oncology patients.

Conclusion

Methods of psychological support depend on the current condition of a patient. The support will be effective if provided in adequate time and place with the patient''s express consent and in line with their individual needs and expectations.     

Autistic autobiography

Autism narratives are not just stories or histories, describing a given reality. They are creating the language in which to describe the experience of autism, and hence helping to forge the concepts in which to think autism. This paper focuses on a series of autobiographies that began with Grandin''s Emergence. These are often said to show us autism from the ‘inside’. The paper proposes that instead they are developing ways to describe experience for which there is little pre-existing language. Wittgenstein has many well-known aphorisms about how we understand other people directly, without inference. They condense what he had found in Wolfgang Köhler''s Gestalt Psychology. These phenomena of direct understanding what other people are doing are, Köhler wrote, ‘the common property and practice of mankind''. They are not the common property and practice of people with autism. Ordinary language is rich in age-old ways to describe what others are thinking, feeling and so forth. Köhler''s phenomena are the bedrock on which such language rests. There is no such discourse for autism, because Köhler''s phenomena are absent. But a new discourse is being made up right now, i.e. ways of talking for which the autobiographies serve as working prototypes.     

Anglo-Canadian Exchange in General Practice: British View of Canadian General Practice

The Canadian general practitioner is remunerated by an item-of-service system of payment which encourages servicing demands rather than needs, discourages delegation of work to paramedical workers, and involves his staff in a massive amount of paper work. He has an excellent hospital attachment, which unfortunately is overdone. His community facilities are piecemeal and his office organization is rudimentary. There are few incentives for good general practice in the community. He spends an inordinate amount of time examining well people. The university departments of general practice are extremely good and much should be heard from them very quickly. The patient''s attitude towards his doctor is quite different from the one prevailing currently in Britain.I returned happily to British general practice.     

Explanation and management of neurological disability.

Patients are often told of the diagnosis of a neurological disability in less than ideal circumstances such that they may not fully comprehend it. Clinicians must be able to sense when the patient''s understanding is imperfect even if superficially he or she appears to take in what has been said and its implications. A programme of further counselling is often required to follow this up. A critical look at current procedures will show how these problems arise. It is suggested that improvements in the care of neurologically disabled patients would follow from improved communication between the many agencies that the concerned in their care and from providing books and other material explaining disability and its treatment. A logical development would be for disabled living centres to be established adjacent to existing neuroscience units.     

Dynamics of thyroid diseases and thyroid‐axis gland masses

Thyroid disorders are common and often require lifelong hormone replacement. Treating thyroid disorders involves a fascinating and troublesome delay, in which it takes many weeks for serum thyroid‐stimulating hormone (TSH) concentration to normalize after thyroid hormones return to normal. This delay challenges attempts to stabilize thyroid hormones in millions of patients. Despite its importance, the physiological mechanism for the delay is unclear. Here, we present data on hormone delays from Israeli medical records spanning 46 million life‐years and develop a mathematical model for dynamic compensation in the thyroid axis, which explains the delays. The delays are due to a feedback mechanism in which peripheral thyroid hormones and TSH control the growth of the thyroid and pituitary glands; enlarged or atrophied glands take many weeks to recover upon treatment due to the slow turnover of the tissues. The model explains why thyroid disorders such as Hashimoto''s thyroiditis and Graves'' disease have both subclinical and clinical states and explains the complex inverse relation between TSH and thyroid hormones. The present model may guide approaches to dynamically adjust the treatment of thyroid disorders.
