The use of dietary supplements is widespread among athletes in all sports and at all levels of competition, as it is in the general population. For the athlete training at the limits of what is sustainable, or for those seeking a shortcut to achieving their aims, supplements offer the prospect of bridging the gap between success and failure. Surveys show, however, that this is often not an informed choice and that the knowledge level among consumers is often low and that they are often influenced in their decisions by individuals with an equally inadequate understanding of the issues at stake...

Salmonella pullorum is the major pathogen that is harmful to the poultry industry in developing countries, and the treatment of chicken diarrhea caused by S. pullorum has become increasingly difficult. In this study, a virulent bacteriophage YSP2, which was able to specifically infect Salmonella, was isolated and characterized. Phage YSP2 was classified in the Siphoviridae family and had a short latent period of 10 min. No bacterial virulence- or lysogenesis-related ORF is present in the YSP2 genome, making it eligible for use in phage therapy...

BACKGROUND/OBJECTIVE: Guidelines concur that postmastectomy radiation therapy (PMRT) in T1-2 tumors with one to three positive (+) lymph nodes (LNs) decreases locoregional recurrence (LRR) but advise limiting PMRT to patients at highest risk to balance against potential harms. In this study, we identify the risks of LRR after mastectomy in patients with T1-2N1 disease, treated with modern chemotherapy, and identify predictors of LRR when omitting PMRT. METHODS: Patients with T1-2N1 breast cancer undergoing mastectomy between 1995 and 2006 were categorized by receipt of PMRT...

This report discusses in detail the case of a patient who underwent a scar revision procedure to have her characteristic self-harm scars altered. A detailed insight into the patient's perspective was gained through semistructured interviews conducted at 6 weeks and 6 months postoperatively. The interviews found that an equally if not more conspicuous scar that was distinct from those created from self-harm had a pronounced psychological benefit for the patient. This article calls for more active management of the psychological sequelae of self-harm scars, with the need to facilitate access to surgical treatment in certain cases...

Immune reconstitution following hematopoietic stem cell transplantation (HSCT) is critical in preventing harmful sequelae in recipients with cytomegalovirus (CMV) infection. To understand the molecular mechanisms underlying immune reconstitution kinetics, we profiled the transcriptome-chromatin accessibility landscape of CMV-specific CD8+ T cells from HCST recipients with different immune reconstitution efficiencies. CMV-specific T cells from HSCT recipients with stable antiviral immunity expressed higher levels of interferon/defense response and cell cycle genes in an interconnected network involving PI3KCG , STAT5B , NFAT , RBPJ , and lower HDAC6 , increasing chromatin accessibility at the enhancer regions of immune and T-cell receptor signaling pathway genes...

Our knowledge of the types of intraoperative patient safety events, their harm to patients, and relationship to postoperative complications is sparse. This study examined intraoperative medical errors (iMEs) and intraoperative adverse events (iAEs) voluntarily reported by providers using two programs at our hospital: surgical debriefing and incident reporting. Among the 3020 surgical procedures assessed, 142 iMEs and 103 iAEs were reported, yielding an overall rate of 8%. Of these events, 135 (55%) were obtained from incident reporting and 110 (45%) from surgical debriefing...

(1) Background: There is a growing need for the development of new methods for the synthesis of nanoparticles. The interest in such particles has raised concerns about the environmental safety of their production methods; (2) Objectives: The current methods of nanoparticle production are often expensive and employ chemicals that are potentially harmful to the environment, which calls for the development of "greener" protocols. Herein we describe the synthesis of gold nanoparticles (AuNPs) using plant extracts, which offers an alternative, efficient, inexpensive, and environmentally friendly method to produce well-defined geometries of nanoparticles; (3) Methods: The phytochemicals present in the aqueous leaf extract acted as an effective reducing agent...

Animals must respond to various threats to survive. Neurons that express calcitonin gene-related peptide in the parabrachial nucleus (CGRPPBN neurons) relay sensory signals that contribute to satiation and pain-induced fear behaviour, but it is unclear how they encode these distinct processes. Here, by recording calcium transients in vivo from individual neurons in mice, we show that most CGRPPBN neurons are activated by noxious cutaneous (shock, heat, itch) and visceral stimuli (lipopolysaccharide). The same neurons are inhibited during feeding, but become activated during satiation, consistent with evidence that CGRPPBN neurons prevent overeating...

The brain cancer medulloblastoma consists of different transcriptional subgroups. To characterize medulloblastoma at the phosphoprotein-signaling level, we performed high-throughput peptide phosphorylation profiling on a large cohort of SHH (Sonic Hedgehog), group 3, and group 4 medulloblastomas. We identified two major protein-signaling profiles. One profile was associated with rapid death post-recurrence and resembled MYC-like signaling for which MYC lesions are sufficient but not necessary. The second profile showed enrichment for DNA damage, as well as apoptotic and neuronal signaling...

Flip-flops may change walking gait pattern, increase muscle activity and joint loading, and predispose wearers to foot problems, despite that quantitative evidence is scarce. The purpose of this study was to examine the lower limb muscle co-contraction and joint contact force in flip-flops gait, and compare with those of barefoot and sports shoes walking. Ten healthy males were instructed to perform over-ground walking at self-selected speed under three footwear conditions: 1) barefoot, 2) sports shoes, and 3) thong-type flip-flops...

OBJECTIVES: Current harm reduction strategies will probably remain insufficient to eliminate HIV transmission among drug users. We aimed to estimate the HIV seroconversion rate among drug users followed at a Harm Reduction Unit (HRU) to evaluate the potential use of PrEP as a prevention tool. DESIGN AND METHODS: A cohort of drug users have been followed at a HRU in Madrid between 2013 and 2016. Individuals who were HIV-negative at baseline and who had at least one re-test for HIV infection were eligible...

Sleep disturbance is a significant issue for patients in intensive care units (ICUs), which can affect their health and recovery from illness. Therefore, it is important to consider ways to address sleep disturbance in these settings. One strategy that has been suggested is the use of 'quiet time' interventions, which involve a defined period where there is a reduction in controllable light and sound, and where interruptions at the patient's bedside are minimised. AIM: To determine the effectiveness of quiet time interventions in improving patients' sleep quality in ICUs; to investigate other potential clinical benefits of quiet time interventions; and to consider the effect of incorporating open visitation when implementing quiet time interventions...
