Biomarker discovery and validation is a critical aim of the medical and scientific community. Research into exercise and diet-related biomarkers aims to improve health, performance, and recovery in military personnel, athletes, and lay-persons. Exercise physiology research has identified individual biomarkers for assessing health, performance, and recovery during exercise training. However, there are few recommendations for biomarker panels for tracking changes in individuals participating in physical activity and exercise training programs...

Meticillin-resistant Staphylococcus aureus (MRSA) continues to be a major public health problem. Vancomycin and teicoplanin have been in clinical use for several decades but their drawbacks are well described. In the last 10 years several antibiotics have been made available for clinical use. Daptomycin and linezolid have been extensively used during this period. Other agents such as ceftaroline, ceftobiprole, dalbavancin, oritavancin, tedizolid, and telavancin have been approved by regulatory agencies since 2009...

Cancer stem cells (CSCs) are found in many cancer types, including breast carcinoma. Breast cancer stem cells (BCSCs) are considered as seed of cancer formation and they are associated with metastasis and genotoxic drug resistance. Several studies highlighted the presence of BCSCs in tumor microenvironment and they are accentuated with several carcinoma events including metastasis and resistance to genotoxic drugs and they also rebound after genotoxic burn. Stemness properties of a small population of cells in carcinoma have provided clues regarding the role of tumor microenvironment in tumor pathophysiology...

PURPOSE: For many transgender individuals, medical intervention is necessary to live as their desired gender. However, little is known about Contextual Factors (i.e., Environmental and Personal) that may act as facilitators and barriers in the health of transgender individuals. Therefore, this paper sought to examine Contextual Factors of the World Health Organization's International Classification of Functioning, Disability, and Health that may facilitate or negatively impact the physical, psychological, and social functioning of transgender individuals...

The effect of oxidative stress on muscle damage inducted by physical exercise is widely debated. It is generally agreed that endurance and intense exercise can increase oxidative stress and generate changes in antioxidant power inducing muscle damage; however, regular and moderate exercise can be beneficial for the health improving the antioxidant defense mechanisms in the majority of cases. Growing evidences suggest that an increased oxidative/nitrosative stress is involved in the pathogenesis of several muscular dystrophies (MDs)...

INTRODUCTION: There are an increasing number of reports describing deep vein thrombosis (DVT) and/or pulmonary embolism (PE) in otherwise healthy endurance athletes. The Wells score is the most commonly used clinical prediction rule to diagnose DVT/PE in clinical populations. However, the Wells score may have limited utility for recognition of DVT/PE in athletes, contributing to missed or delayed diagnosis. OBJECTIVE: We performed an analysis of the ability of the Wells score to identify DVT/PE events in athletes through a review of published case reports...

REVIEW

A single bout of resistance training induces residual fatigue, which may impair performance during subsequent endurance training if inadequate recovery is allowed. From a concurrent training standpoint, such carry-over effects of fatigue from a resistance training session may impair the quality of a subsequent endurance training session for several hours to days with inadequate recovery. The proposed mechanisms of this phenomenon include: (1) impaired neural recruitment patterns; (2) reduced movement efficiency due to alteration in kinematics during endurance exercise and increased energy expenditure; (3) increased muscle soreness; and (4) reduced muscle glycogen...

In the past few years, there has been increased recognition that children, who have faced traumatic incidences, can develop post-traumatic stress disorder (PTSD), just like in adults. We present a case of PTSD in a 6-year-old child who endured three surgical procedures because he was suffering from a congenital cranial stenosis (Pfeiffer) syndrome. Because of repetitive painful episodes, resulting from the syndrome, and then post-surgical complications, the child developed behavioral outbursts, hypervigilence, concentration problems, and irritability...

Tart cherry (TC) juice has many antioxidant and anti-inflammatory polyphenol compounds. TC lessens pain and accelerates strength recovery after exercise and decreases blood markers of inflammation/oxidative stress. These improvements occur in both strength and endurance exercise. TC supplementation may not be optimal during the adaptation/build stage of training. However, excessive inflammatory/oxidative stress during single-day intense training/competition or multiday tournaments may delay return to peak form...

The cardiovascular benefits of regular exercise have been well described, including a significant reduction in cardiovascular morbidity and mortality for those meeting recommended guidelines. Yet the impact of physical activity on the incidence of atrial fibrillation (AF) has been less clear. This review seeks to define the optimal dose and duration for the prevention and treatment of AF. In doing so, we review the evidence that supports a decline in AF risk for those who achieve a weekly physical activity dose slightly above the current recommended guidelines...

REVIEW

Sexual assault (SA) is a common and deleterious form of trauma. Over 40years of research on its impact has suggested that SA has particularly severe effects on a variety of forms of psychopathology, and has highlighted unique aspects of SA as a form of trauma that contribute to these outcomes. The goal of this meta-analytic review was to synthesize the empirical literature from 1970 to 2014 (reflecting 497 effect sizes) to understand the degree to which (a) SA confers general risk for psychological dysfunction rather than specific risk for posttraumatic stress, and (b) differences in studies and samples account for variation in observed effects...

The impacts of neoliberal or market-based social security reforms in health have been extensively studied. How such reforms transformed employment-related insurance and entitlements, however, has received significantly less attention. This study aims to understand how the employment insurance system operates in Colombia and to assess how the experience of workers seeking social security entitlements relates to the system's structure. We conducted an ethnographic study of the Colombian Occupational Risk System between May 2014 and March 2016, with two main components: 1) analysis of the system itself through in-depth interviews with 32 people working in leadership positions and a systematic review of the system's most important legislation, and 2) a study of people who experienced problems receiving entitlements and were challenging the assessment of their work-related illness or accident...

RATIONALE: Following prolonged endurance events such as marathons, elevated levels of cardiospecific biomarkers are commonly reported. Although transiently raised levels are generally not considered to indicate clinical myocardial damage, comprehension of this phenomenon remains incomplete. The popularity of high-intensity interval training highlights a paucity of research measuring cardiac biomarker response to this type of exercise. This a posteriori case report discusses the elevation of cardiac troponins (cTn) associated with short interval, high-intensity exercise...

Predator avoidance and prey capture are among the most vital of animal behaviors. They require fast reactions controlled by comparatively straightforward neural circuits often containing giant neurons, which facilitates their study with electrophysiological techniques. Naturally occurring avoidance behaviors, in particular, can be easily and reliably evoked in the laboratory, enabling their neurophysiological investigation. Studies in the laboratory alone, however, can lead to a biased interpretation of an animal's behavior in its natural environment...

INTRODUCTION: Exercise-based cardiac rehabilitation (CR) independently alters the clinical course of cardiovascular diseases resulting in a significant reduction in all-cause and cardiac mortality. However, only 15%-30% of all eligible patients participate in a phase 2 ambulatory programme. The uptake rate of community-based programmes following phase 2 CR and adherence to long-term exercise is extremely poor. Newer care models, involving telerehabilitation programmes that are delivered remotely, show considerable promise for increasing adherence...

Fatigability is defined as the extent of fatigue in the context of activity and differs from the term used in exercise literature to describe muscle endurance characteristics. Many fatigability measures are available, but no studies have thoroughly evaluated them for adequate incorporation of fatigability concepts. This integrative review provides an overall assessment of existing fatigability measures and then evaluates each in depth. A database search and hand search produced 14 studies for review. Fatigability measurement took three forms: self-reported fatigability, perceived fatigability (self-reported fatigue following a defined performance test), and performance fatigability (performance deterioration)...

Yuho Kim, Matthew Triolo, David A Hood
Mitochondria are characterized by its pivotal roles in managing energy production, reactive oxygen species, and calcium, whose aging-related structural and functional deteriorations are observed in aging muscle. Although it is still unclear how aging alters mitochondrial quality and quantity in skeletal muscle, dysregulation of mitochondrial biogenesis and dynamic controls has been suggested as key players for that. In this paper, we summarize current understandings on how aging regulates muscle mitochondrial biogenesis, while focusing on transcriptional regulations including PGC-1α, AMPK, p53, mtDNA, and Tfam...

Matthew J Watt, Yunsheng Cheng
Triglycerides are stored within lipid droplets in skeletal muscle and can be hydrolyzed to produce fatty acids for energy production through β-oxidation and oxidative phosphorylation. While there was some controversy regarding the quantitative importance of intramyocellular triglyceride (IMTG) as a metabolic substrate, recent advances in proton magnetic resonance spectroscopy and confocal microscopy support earlier tracer and biopsy studies demonstrating a substantial contribution of IMTG to energy production, particularly during moderate-intensity endurance exercise...

INTRODUCTION: It is 40 years since the initial documentation of the efficacy of bacille Calmette-Guérin (BCG) in the management of non-muscle invasive bladder cancer (NMIBC) and probably an opportune a time as any to retrace the origins of this development and to reflect on the progress that has occurred on the use of immune modifiers in the treatment of NMIBC. MATERIALS AND METHODS: A PubMed search for publications on the history of BCG was conducted, and those related to the development of the vaccine for protection against tuberculosis as well as those published in the last 40 years related to its use for treatment for NMIBC were selected for review...
