BACKGROUND: Interest in the Senian capability framework as an alternative approach to wellbeing measurement has increased in recent decades. The aim of this study was to look at the extent to which an individual's capability to achieve wellbeing in one dimension is associated with his or her attempt to achieve wellbeing in another dimension in a fragile setting affected by conflict. METHODS: Capability is defined as the ability to achieve health, knowledge, and wealth and is measured as latent variables using a structural equation model...

Perceptual learning, improvement in discriminative ability as a consequence of training, is one of the forms of sensory system plasticity that has driven profound changes in our conceptualization of sensory cortical function. Psychophysical and neurophysiological studies of auditory perceptual learning have indicated that the characteristics of the learning, and by implication the nature of the underlying neural changes, are highly task specific. Some studies in animals have indicated that recruitment of neurons to the population responding to the training stimuli, and hence an increase in the so-called cortical "area of representation" of those stimuli, is the substrate of improved performance, but such changes have not been observed in other studies...

Humanitarian organisations often work alongside those responsible for serious wrongdoing. In these circumstances, accusations of moral complicity are sometimes levelled at decision makers. These accusations can carry a strong if unfocused moral charge and are frequently the source of significant moral unease. In this paper, we explore the meaning and usefulness of complicity and its relation to moral accountability. We also examine the impact of concerns about complicity on the motivation of humanitarian staff and the risk that complicity may lead to a retreat into moral narcissism...

Corruption in healthcare generally and specifically in the pharmaceutical arena has recently been highlighted in reports by Transparency International. This article focuses on four areas of corruption: legislative/regulatory, financial, ideological/ethical, and communications. The problems identified and the solutions considered focus on structural considerations affecting how pharmaceuticals are discovered, developed, distributed, and ultimately used in clinical settings. These include recourse to user fees in the regulatory sphere, application of intellectual property rights to medical contexts (patents and access to research data), commercial sponsorship of ghost writing and guest authors, linkage/delinkage of the funding of research and overall health objectives to/from drug pricing and sales, transparency of payments to healthcare professionals and institutions, and credible regulatory sanctions...

BACKGROUND CONTEXT: The current standard of care for prediction of survival of cancer staging is based on TNM staging. However, for patients with spinal metastasis, who all have identical stage IV disease, identifying accurate prognostic markers of survival would allow better treatment stratification between more aggressive treatment strategies or palliation. Analytic morphometrics enables physicians to quantify patient frailty by measuring lean muscle mass. Morphometrics also predicts survival in patients with lung cancer metastases to the spine...

Evidences suggest the contributive role of early-life stress (ELS) to affective and anxiety disorders. Chronic exposure to the same stressor may generate habituation, while the exposure to different and repeated stressors gradually promotes maladaptive plasticity. Therefore, to further understand the effects of heterotypic stressors during early life period, male Wistar rat pups (P1-P21) were exposed to Multimodal ELS paradigm. Results indicate pups did not habituate to multimodal ELS and neonates respond to both physical and psychogenic stressors...

Background: Military working dogs (MWDs) are a major asset in the theater of operations. Their unique abilities make them ideal for tasks such as tracking, patrol, and scent detection. MWDs deployed to a war zone are exposed to harsh environments and battlefield dangers that increase their risk of disease, injuries, and death. Although canines have been used extensively in Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF), no published studies have reported detailed causes of death among MWDs deployed to these conflicts...

Background: Brazil has sought to use economic evaluation to support healthcare decision-making processes. While a number of health economic evaluations (HEEs) have been conducted, no study has systematically reviewed the quality of Brazilian HEE. The objective of this systematic review was to provide an overview regarding the state of HEE research and to evaluate the number, characteristics, and quality of reporting of published HEE studies conducted in a Brazilian setting. Methods: We systematically searched electronic databases (MEDLINE, EMBASE, Latin American, and Caribbean Literature on Health Sciences Database, Scientific Electronic Library Online, NHS Economic Evaluation Database, health technology assessment Database, Bireme, and Biblioteca Virtual em Saúde Economia da Saúde ); citation indexes (SCOPUS, Web of Science), and Sistema de Informação da Rede Brasileira de Avaliação de Tecnologia em Saúde ...

STUDY QUESTION: How does the formation of the blood-testis barrier (BTB), as reflected by the expression of connexin 43 and claudin 11 proteins during the pubertal transition period, take place in vitro compared to samples from a large cohort of pre/peripubertal boys? SUMMARY ANSWER: The BTB connexin 43 and claudin 11 expression patterns appeared to be partially achieved in organotypic culture when compared to that in samples from 71 pre/peripubertal patients. WHAT IS KNOWN ALREADY: Although alterations in the protein expression patterns of the BTB, whose main components are connexin 43 and claudin 11, are known to be associated with impaired spermatogenesis in mice and adult men, there is a lack of knowledge on its formation in pre-peripubertal human tissue both in vitro and in vivo...

CONTEXT: For medical education researchers, a key concern may be the practicalities of gaining ethical approval where this is a national or local requirement. However, in qualitative studies, where the dynamics of human interaction pervade, ethical considerations are an ongoing process which continues long after approval has been granted. Responding to ethical dilemmas arising 'in the moment' requires a reflexive approach whereby the researcher questions his/her own motivations, assumptions and interests...

STUDY QUESTION: Is ceramide-1-phosphate (C1P) an ovarian protective agent during alkylating chemotherapy? SUMMARY ANSWER: Local administration of C1P drastically reduces ovarian damage induced by cyclophosphamide (Cy) via protection of follicular reserve, restoration of hormone levels, inhibition of apoptosis and improvement of stromal vasculature, while protecting fertility, oocyte quality and uterine morphology. WHAT IS KNOWN ALREADY: Cancer-directed therapies cause accelerated loss of ovarian reserve and lead to premature ovarian failure (POF)...

STUDY QUESTION: Is 8% O2 a better percentage of atmospheric oxygen for long-term cultures of human primary term cytotrophoblasts than the conventional 21% O2 traditionally used in cell culture? SUMMARY ANSWER: Human primary term cytotrophoblasts are able to differentiate into syncytiotrophoblasts under both atmospheric oxygen levels. WHAT IS KNOWN ALREADY: Cell culture is traditionally done under 21% O2, which is equal to a pO2 of ~160 mm Hg...
