    Aim. This paper presents a review of the qualitative literature which examines the experiences of patients with coronary heart disease. The paper also assesses whether the experiences of both female and male patients are reflected in the literature and summarizes key themes. Background. Understanding patients' experiences of their illness is important for coronary heart disease prevention and education. Qualitative methods are particularly suited to eliciting patients' detailed understandings and perceptions of illness. As much previous research has been 'gender neutral', this review pays particular attention to gender. Methods. Published papers from 60 qualitative studies were identified for the review through searches in MEDLINE, EMBASE, CINAHL, PREMEDLINE, PsychINFO, Social Sciences Citation Index and Web of Science using keywords related to coronary heart disease. Findings. Early qualitative studies of patients with coronary heart disease were conducted almost exclusively with men, and tended to generalize from 'male' experience to 'human' experience. By the late 1990s this pattern had changed, with the majority of studies including women and many being conducted with solely female samples. However, many studies that include both male and female coronary heart disease patients still do not have a specific gender focus. Key themes in the literature include interpreting symptoms and seeking help, belief about coronary 'candidates' and relationships with health professionals. The influence of social roles is important: many female patients have difficulties reconciling family responsibilities and medical advice, while male patients worry about being absent from work. Conclusions. There is a need for studies that compare the experiences of men and women. There is also an urgent need for work that takes masculinity and gender roles into account when exploring the experiences of men with coronary heart disease

    Patients with primary immunodeficiencies are a reservoir of poliovirus and a risk to polio eradication

    ABSTARCT: Immunodeficiency-associated vaccine-derived polioviruses (iVDPVs) have been isolated from primary immunodeficiency (PID) patients exposed to oral poliovirus vaccine (OPV). Patients may excrete poliovirus strains for months or years; the excreted viruses are frequently highly divergent from the parental OPV and have been shown to be as neurovirulent as wild virus. Thus, these patients represent a potential reservoir for transmission of neurovirulent polioviruses in the post-eradication era. In support of WHO recommendations to better estimate the prevalence of poliovirus excreters among PIDs and characterize genetic evolution of these strains, 635 patients including 570 with primary antibody deficiencies and 65 combined immunodeficiencies were studied from 13 OPV-using countries. Two stool samples were collected over 4 days, tested for enterovirus, and the poliovirus positive samples were sequenced. Thirteen patients (2%) excreted polioviruses, most for less than 2 months following identification of infection. Five (0.8%) were classified as iVDPVs (only in combined immunodeficiencies and mostly poliovirus serotype 2). Non-polio enteroviruses were detected in 30 patients (4.7%). Patients with combined immunodeficiencies had increased risk of delayed poliovirus clearance compared to primary antibody deficiencies. Usually, iVDPV was detected in subjects with combined immunodeficiencies in a short period of time after OPV exposure, most for less than 6 months. Surveillance for poliovirus excretion among PID patients should be reinforced until polio eradication is certified and the use of OPV is stopped. Survival rates among PID patients are improving in lower and middle income countries, and iVDPV excreters are identified more frequently. Antivirals or enhanced immunotherapies presently in development represent the only potential means to manage the treatment of prolonged excreters and the risk they present to the polio endgame.

    Influences of organizational features of healthcare settings on clinical decision making: qualitative results from a cross-national factorial experiment.

    Item does not contain fulltextA proliferating literature documents cross-national variation in medical practice and seeks to explain observed differences in terms of the presence of certain kinds of healthcare systems, economic, and cultural differences between countries. Less is known about how providers themselves understand these influences and perceive them as relevant to their clinical work. Using qualitative data from a cross-national factorial experiment in the United States and United Kingdom, we analyze 244 primary care physicians' explanations of how organizational features of their respective healthcare settings influence the treatment decisions they made for a vignette patient, including affordability of care; within-system quality deficits; and constraints due to patient behavior. While many differences are attributed to financial constraints deriving from two very differently structured healthcare systems, in other ways they are reflections of cultural and historical expectations regarding medical care, or interactions between the two. Implications, including possible challenges to the implementation of universal care in the USA, are discussed

METHODS: We conducted a factorial experiment, employing 2 clinically authentic filmed scenarios, to examine country differences in the treatment of diabetes, while controlling the effects of selected characteristics of patients and physicians. The patient in the first scenario presented with (undiagnosed) signs and symptoms strongly suggestive of diabetes, while the second scenario presented an already diagnosed patient with an emerging foot neuropathy. Physicians were asked how they would diagnose and manage the patients after watching the video vignettes using a questionnaire with standardized and open-ended questions. RESULTS: Regarding the first (undiagnosed) case, US doctors would ask significantly more questions than physicians from the UK and Germany (P < 0.001). German physicians would give less advice but would want to see the patient again much sooner (P < 0.001). Regarding the diagnosed case with an emerging foot neuropathy, US physicians would be most active in terms of questioning, testing, prescribing, and advice giving. Again, physicians from Germany would be less active in terms of therapeutic strategies but they would like to see the patient again sooner (P = 0.005). CONCLUSIONS: Although physicians in the 3 countries encountered exactly the same patient, differences in diagnostic and management decisions were evident. The experimental design provides unconfounded estimates of health system differences while simultaneously controlling for the effects of selected patient attributes and physician characteristics.1 april 201

    IAP antagonists target cIAP1 to induce TNFalpha-dependent apoptosis.

    XIAP prevents apoptosis by binding to and inhibiting caspases, and this inhibition can be relieved by IAP antagonists, such as Smac/DIABLO. IAP antagonist compounds (IACs) have therefore been designed to inhibit XIAP to kill tumor cells. Because XIAP inhibits postmitochondrial caspases, caspase 8 inhibitors should not block killing by IACs. Instead, we show that apoptosis caused by an IAC is blocked by the caspase 8 inhibitor crmA and that IAP antagonists activate NF-kappaB signaling via inhibtion of cIAP1. In sensitive tumor lines, IAP antagonist induced NF-kappaB-stimulated production of TNFalpha that killed cells in an autocrine fashion. Inhibition of NF-kappaB reduced TNFalpha production, and blocking NF-kappaB activation or TNFalpha allowed tumor cells to survive IAC-induced apoptosis. Cells treated with an IAC, or those in which cIAP1 was deleted, became sensitive to apoptosis induced by exogenous TNFalpha, suggesting novel uses of these compounds in treating cancer
