Background: Studies have shown that 5α-reductase inhibitors (5-ARIs) decrease the risk for low-grade prostate cancer (PC), but results are conflicting concerning high-grade PCs. The objective of the present study is to evaluate the association between 5-ARI treatment for lower urinary tract symptoms and the risk for PC. Methods: This is a population-based prospective study on all men age 40 years and older with at least one prostate-specific antigen (PSA) test in Stockholm County from January 2007 until December 2015...

Background: Throughout history, traumatic amputation of the lower extremity has been a notable feature of all conflicts involving explosive incidents. Even at the close of the recent conflicts in Afghanistan, there were deaths that were deemed "potentially survivable." The purpose of this study is to characterize lower extremity blast injury and to determine if their amputation levels and associated injury characteristics correlate with a higher risk of mortality. Methods: the UK Joint Theatre Trauma Registry (JTTR) was interrogated to identify all lower extremity traumatic amputations sustained in both Iraq and Afghanistan between January 2003 and the end of UK operations in August 2014...

Introduction: The current evolution of surgical practices is increasingly trending toward hyper-specialization. For military surgeons, their practice in France does not differ from their civilian counterparts. In contrast, in external operations, they have to deal with specific war injuries in austere conditions. They are also required to take care of local populations. Therefore, specific training is necessary, and the French Military Health Service Academy (Ecole du Val-de-Grâce) Paris has set up a specific training called Advanced Course for Deployment Surgery (ACDS) in 2007...

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...

Heparan sulfate 3-O-sulfotransferases (HS3STs) catalyze the final maturation step of heparan sulfates. Although seven HS3ST isozymes have been described in human, 3-O-sulfation is a relatively rare modification, and only a few biological processes have been described to be influenced by 3-O-sulfated motifs. A conflicting literature has recently reported that HS3ST2, 3A, 3B and 4 may exhibit either tumor-promoting or anti-oncogenic properties, depending on the model used and cancer cell phenotype. Hence, we decided to compare the consequences of the overexpression of each of these HS3STs in the same cellular model...

Tattoos have become increasingly popular in the U.S. among the general population. Furthermore, the popularity of body art, primarily tattoos, among nursing students generates issues about professionalism in academics and in clinical settings. Nursing faculty are faced with conflicting views on cultural awareness, professionalism, and self-expression. With nursing viewed as one of the most trusted professions, the policy of covering tattoos should be discussed, and more research is necessary.

Oxidative stress can contribute to an acceleration of telomere erosion, leading to cellular senescence and aging. Increased investment in reproduction is known to accelerate senescence, generally resulting in reduced future reproductive potential and survival. To better understand the role played by oxidative status and telomere dynamics in the conflict between maintenance and reproduction, it is important to determine how these factors are related in parents and their offspring. We investigated the relationship between oxidative status and telomere measurements in pied flycatchers (Ficedula hypoleuca)...

This article considers the significance of eating and drinking within a series of diaries and journals produced in British colonial India during the Indian Rebellion of 1857. The discussion of food and drink in this context was not simply a means to add color or compelling detail to these accounts, but was instead a vital ingredient of the authors' understanding of health and medical treatment. These texts suggest a broader colonial medical understanding of the importance of regulating diet to maintain physical health...

Systemic lupus erythematosus (SLE) is an inadequately defined syndrome. Etiology and pathogenesis remain largely unknown. SLE is on the other hand a seminal syndrome that has challenged immunologists, biologists, genetics, and clinicians to solve its nature. The syndrome is characterized by multiple, etiologically unlinked manifestations. Unexpectedly, they seem to occur in different stochastically linked clusters, although single gene defects may promote a smaller spectrum of symptoms/criteria typical for SLE...

When a group engages in immoral behavior, group members face the whistleblower's dilemma: the conflict between remaining loyal to the group and standing up for other moral concerns. This study examines the developmental origins of this dilemma by investigating 5-year-olds' whistleblowing on their in- vs. outgroup members' moral transgression. Children ( n = 96) watched puppets representing their ingroup vs. outgroup members commit either a mild or a severe transgression. After the mild transgression, children tattled on both groups equally often...

For many years it has been known that high doses of long chain omega-3 fatty acids are beneficial in the treatment of hypertriglyceridaemia. Over the last three decades, there has also been a wealth of in vitro and in vivo data that has accumulated to suggest that long chain omega-3 fatty acid treatment might be beneficial to decrease liver triacylglycerol. Several biological mechanisms have been identified that support this hypothesis; notably, it has been shown that long chain omega-3 fatty acids have a beneficial effect: a) on bioactive metabolites involved in inflammatory pathways, and b) on alteration of nuclear transcription factor activities such as peroxisome proliferator-activated receptors (PPARs), sterol regulatory element-binding protein 1c (SREBP-1c) and carbohydrate-responsive element-binding protein (ChREBP), involved in inflammatory pathways and liver lipid metabolism...

Multidisciplinary cancer clinics (MDCCs) are recognized in cancer care as an alternate model of care for lung cancer patients. However, the precise MDCC characteristics that could potentially improve the quality of care in lung cancer care have not been clearly defined. We performed a systematic review of the data regarding MDCCs in the treatment of patients with lung cancer to summarize and evaluate the available evidence and to determine valuable clinic characteristics and projected outcomes. We searched Embase, Cochrane, Medline, PubMed, and Web of Science through April 2017 for studies that included ≥ 2 physician specialties in a MDCC for lung cancer...

Work over the last 15 years on the control of pulsatile LH secretion has focused largely on a set of neurons in the arcuate nucleus (ARC) that contains two stimulatory neuropeptides, critical for fertility in humans (kisspeptin and neurokinin B (NKB)) and the inhibitory endogenous opioid peptide (EOP), dynorphin, and are now known as KNDy (kisspeptin-NKB-dynorphin) neurons. In this review, we consider the role of each of the KNDy peptides in the generation of GnRH pulses and the negative feedback actions of ovarian steroids, with an emphasis on NKB and dynorphin...

BACKGROUND: A strategy for minimising the time and obstacles to accessing systematic reviews of health system evidence is to collect them in a freely available database and make them easy to find through a simple 'Google-style' search interface. PDQ-Evidence was developed in this way. The objective of this study was to compare PDQ-Evidence to six other databases, namely Cochrane Library, EVIPNet VHL, Google Scholar, Health Systems Evidence, PubMed and Trip. METHODS: We recruited healthcare policy-makers, managers and health researchers in low-, middle- and high-income countries...

This study tests specific competing hypotheses from social dominance theory/realistic conflict theory (RCT) versus system justification theory about the role of social status. In particular, it examines whether system justification belief and effects are stronger among people with low socioeconomic status, and in less socially developed and unequal nations than among better-off people and countries. A cross-national survey was carried out in 19 nations from the Americas, Western and Eastern Europe, Asia, and Oceania using representative online samples ( N = 14,936, 50...

The increasing prevalence of postnatal anxiety highlights the need for summarizing the recent research on this condition to inform screening and intervention efforts. This narrative review of the literature was derived from a search on PubMed and PsycINFO for papers published since 2010. The demographic risk factors for postnatal anxiety include being a young mother, having more education and being employed. Childbirth risk factors include being primiparous in one sample and multiparous in another, caesarean delivery, fear of the birth and of death during delivery, lack of control during labor, low self-confidence for the delivery and the delivery staff, and premature delivery...
