Androgens are steroid hormones with pleotropic and diverse biochemical and physiological functions, and androgen deficiency exerts a negative impact on human health. Testosterone (T) either directly or via its transformation into the more potent metabolite 5α-dihydrotestosterone (5α-DHT) or via aromatization into estradiol (E2) modulates important biochemical signaling pathways of human physiology and plays a critical role in the growth and/or maintenance of functions in a host of tissues and organs. T and 5α-DHT play an important role in regulating physiology of the muscle, adipose tissue, liver, bone, and central nervous system, as well as reproductive and sexual functions...

BACKGROUND: Non-verbal behaviour is fundamental to social interaction. Patients with schizophrenia display an expressivity deficit of non-verbal behaviour, exhibiting behaviour that differs from both healthy subjects and patients with different psychiatric diagnoses. The present study aimed to explore the association between non-verbal behaviour and symptom domains, overcoming methodological shortcomings of previous studies. SAMPLING AND METHODS: Standardised interviews with 63 outpatients diagnosed with schizophrenia were videotaped...

Alejandra T Rabadán, Vilma A Tripodoro
In healthcare, an ethical concern that arises during the decision making process is considered to be a bioethical dilemma. It is often the case that in the absence of proper deliberation, the problem is transferred to a bioethics committee, not even representing precisely a dilemma. Bioethics emerged as a discipline in the mid-20th century. It is defined as a support to decision-making in ethical dilemmas centered on two aspects: ethics of clinical investigation, focused on protecting the rights of research subjects, and bioethics in medical practice, of an advisory nature...

BACKGROUND: Anaerobic threshold (AT) is recognized as objective and direct measurement that reflects variations in metabolism of skeletal muscles during exercise. Its prognostic value in heart diseases of non-chagasic etiology is well established. However, the assessment of risk of death in Chagas heart disease is relatively well established by Rassi score. But, the added value that AT can bring to Rassi score has not been studied yet. OBJECTIVES: To assess whether AT presents additional effect to Rassi score in patients with chronic Chagas' heart disease...

As a composite concept, negative affect comprises various aversive emotional experiences, such as irritability and nervousness. It is a critical motivational factor that helps maintain smoking behavior, and contributes significantly to smoking cessation failure as a core withdrawal symptom. Prior research has indicated an important role of nicotinic mechanisms in negative affect processing. The most effective smoking cessation medication, varenicline, targets nicotinic acetylcholine receptors (nAChRs) as a partial agonist, while another first-line cessation medication, bupropion, has shown antagonistic effects on nAChRs...

The development and advancement of next generation sequencing have not only sped up the process of identifying rare variants, but have also enabled scientists to explore all variants in a single individual. The Pakistani population has a high ratio of first degree consanguinity, which is why it is a rich source for various kinds of genetic disorders. Due to the heterogeneous composition of Pakistani population, the likelihood of genetic heterogeneity for each disorder is high. Therefore, the compilation and organization of such vast genetic data is necessary to facilitate access for analysis and interpretation to researchers and medical geneticists...

Introduction Historically, the quality and performance of prehospital emergency care (PEC) has been assessed largely based on surrogate, non-clinical endpoints such as response time intervals or other crude measures of care (eg, stakeholder satisfaction). However, advances in Emergency Medical Services (EMS) systems and services world-wide have seen their scope and reach continue to expand. This has dictated that novel measures of performance be implemented to compliment this growth. Significant progress has been made in this area, largely in the form of the development of evidence-informed quality indicators (QIs) of PEC...

BACKGROUND: Elderly drivers are an increasing group in society. Previous research has found that functional and cognitive abilities are more important for driving abilities than biological age. In an attempt to conserve independent mobility for elderly drivers, many researchers have focused on elderly drivers diagnosed with cognitive decline (mild cognitive impairment or mild Dementia). This study is the first to focus on elderly drivers with cognitive complaints or suspected of diminished fitness to drive by an (in)formal caregiver as an at-risk group...

Several children's hospitals and medical schools across Texas have child abuse pediatricians (CAPs) who work closely with child protection workers to help ensure accurate assessments of the likelihood of maltreatment in cases of suspected abuse and neglect. Since the state does not mandate which cases should be referred to a CAP center, we were interested in studying factors that may influence workers' decisions to consult a CAP. We used a mixed methods study design consisting of a focus group followed by a survey...

The "Asthma Control Questionnaire" (ACQ) is a very common questionnaire for assessing asthma control. This study compares different ACQ versions in a self-monitoring program over a 12-week period combining them with patients' self-measurements of peak expiratory flow (PEF) and forced expiratory volume in one second (FEV1). The objective was to test the feasibility of FEV1-self-measurements and to compare ACQ versions regarding possible additional information given by lung function. In this prospective multicenter observational study 100 adult asthma patients, recruited at six family practices and two pulmologists' private practices in Germany, completed the ACQ weekly, performing self-measurements of PEF and FEV1...

Orthostatic intolerance (OI), having difficulty tolerating an upright posture because of symptoms or signs that abate when returned to supine, is common in pediatrics. For example, ∼40% of people faint during their lives, half of whom faint during adolescence, and the peak age for first faint is 15 years. Because of this, we describe the most common forms of OI in pediatrics and distinguish between chronic and acute OI. These common forms of OI include initial orthostatic hypotension (which is a frequently seen benign condition in youngsters), true orthostatic hypotension (both neurogenic and nonneurogenic), vasovagal syncope, and postural tachycardia syndrome...
