Periodization of swim training in the final training phases prior to competition and its effect on performance have been poorly described. PURPOSE: We modelled the relationships between the final 11 weeks of training and competition performance in 138 elite sprint, middle-distance and distance swimmers over 20 competitive seasons. METHODS: Total training load (TTL), strength training (ST), low-to medium and high-intensity training variables were monitored. Training loads were scaled as a percentage of the maximal volume measured at each intensity level...

To be effective, state of the art machine learning technology needs large amounts of annotated data. There are numerous compelling applications in healthcare that can benefit from high performance automated decision support systems provided by deep learning technology, but they lack the comprehensive data resources required to apply sophisticated machine learning models. Further, for economic reasons, it is very difficult to justify the creation of large annotated corpora for these applications. Hence, automated annotation techniques become increasingly important...

Background • Vitamin K1 and K2 are not typically common in a Western diet because they are found in a variety of fermented foods. Vitamin K2 in particular has been demonstrated to restore mitochondrial function and has a key role in production of mitochondrial adenosine triphosphate. Thus, it is reasonable to speculate that dietary supplementation with vitamin K2 could increase the function of muscle with high mitochondrial content (ie, skeletal and cardiac muscle). Objective • The purpose of this study was to determine if 8 wk of dietary supplementation with Vitamin K2 could alter cardiovascular responses to a graded cycle ergometer test...

OBJECTIVE: The five Nordic countries comprise 25 million people, and have similar treatment traditions and healthcare systems. To take advantage of these similarities, a collaborative group (Nordic Renal Cancer Group, NORENCA) was founded in 2015. MATERIALS AND METHODS: A questionnaire of 17 questions on renal tumor management and surgical education was designed and sent to 91 institutions performing renal tumor surgery in 2015. The response rate was 68% (62 hospitals), including 28 academic, 25 central and nine district hospitals...

INTRODUCTION: Laparoscopic inguinal hernia repair has been shown to have significant benefits when compared to open inguinal hernia repair, yet remains underutilized in the United States. The traditional model of short, hands-on, cognitive courses to enhance the adoption of new techniques fails to lead to significant levels of practice implementation for most surgeons. We hypothesized that a comprehensive program would facilitate the adoption of laparoscopic inguinal hernia repair (TEP) for practicing surgeons...

The International Society of Sports Nutrition (ISSN) provides an objective and critical review related to the intake of protein for healthy, exercising individuals. Based on the current available literature, the position of the Society is as follows:An acute exercise stimulus, particularly resistance exercise, and protein ingestion both stimulate muscle protein synthesis (MPS) and are synergistic when protein consumption occurs before or after resistance exercise.For building muscle mass and for maintaining muscle mass through a positive muscle protein balance, an overall daily protein intake in the range of 1...

PURPOSE: Left atrial (LA) structure and function are important markers of adverse cardiovascular outcomes. Tissue-tracking cardiovascular magnetic resonance (CMR) accurately quantifies LA volume, strain, and strain rate based on biplane long-axis imaging. We aimed to assess the accuracy of the LA indices quantification from single-plane tissue-tracking CMR. METHODS: We included 162 patients (mean age 56±15, male 70%) from a prospective cohort study whose cine CMR images in sinus rhythm were available in both four-chamber and two-chamber views...

BACKGROUND: High intensity interval training (HIIT) increases maximal oxygen uptake similar to aerobic exercise. However, changes in body composition are equivocal in response to HIIT. AIM: We examined changes in body composition and dietary restraint in response to 20 sessions of HIIT varying in structure. METHODS: Thirty nine active men and women (age and VO2max = 22.5 ± 4.4 yr and 40.1 ± 5.6 mL/kg/min) were randomized to one of three periodized HIIT regimes performed on a cycle ergometer...

BACKGROUND: Elite water polo athletes undergo heavy training programs throughout the year, but especially to prepare major competitions, such as the Olympics. Optimal athletic performance is a result of many factors, including proper management of the intensity and volume of training, nutrition and recovery between training sessions. When training is excessive in relation to recovery may occur non functional overreaching (NFO). NFO can degenerate into overtraining syndrome (OTS) resulting in a decrease in athletic performance, with likely changes in body weight and body composition...

INTRODUCTION: Advice (BBA) into the standards of patients' care in both monosymptomatic and non-monosymptomatic nocturnal enuresis. Although the idea of this recommendation was clear and reflects clinical experience, duration and efficacy have not been definitely established. Recent data have demonstrated the lack of efficacy of BBA and a fierce discussion has ensued. The present study was aimed to assess the efficacy of BBA in a group of previously untreated children with primary monosymptomatic nocturnal enuresis (MNE)...

INTRODUCTION: Chronic alcohol abuse is associated with neurophysiological changes in brain activity; however, these changes are not well localized in humans. Non-human primate models of alcohol abuse enable control over many potential confounding variables associated with human studies. The present study utilized high-resolution magnetoencephalography (MEG) to quantify the effects of chronic EtOH self-administration on resting state (RS) brain function in vervet monkeys. METHODS: Adolescent male vervet monkeys were trained to self-administer ethanol (n=7) or an isocaloric malto-dextrin solution (n=3)...

In the setting of "living high," it is unclear whether high-intensity interval training (HIIT) should be performed "low" or "high" to stimulate muscular and performance adaptations. Therefore, 10 physically active males participated in a 5-week "live high-train low or high" program (TR), whilst eight subjects were not engaged in any altitude or training intervention (CON). Five days per week (~15.5 h per day), TR was exposed to normobaric hypoxia simulating progressively increasing altitude of ~2,000-3,250 m...

This study aimed to identify the most sensible heart rate-based indices to physical measures of training load and intensity. Twenty professional football players competing in the Russian league and in the UEFA Champions League were monitored during 15 training sessions (270 individual records) using GPS devices (10 Hz) and heart rate telemetry. Expert knowledge and a collinearity r < .5 were used initially to select the external physical markers for the final analysis. A multivariate-adjusted within-subjects model was employed to quantify the correlations between heart rate indices with various measures of training intensity and load...

BACKGROUND: A core principle in surgery is that high surgical volumes are conducive toward better outcomes. Ultra-high volume centers (UHVCs) have now emerged in thoracic surgery in China that now perform a volume of thoracic operations far greater than even traditional international centers of excellence. METHODS: In 2016, two hospitals in Shanghai performed over 10,000 major pulmonary, esophageal and mediastinal resections each. A qualitative analysis of the lessons learned in achieving such large operation volumes was undertaken...

BACKGROUND: Approximately 10% of admissions to acute-care hospitals are associated with an adverse event. Analysis of incident reports helps to understand how and why incidents occur and can inform policy and practice for safer care. Unfortunately our capacity to monitor and respond to incident reports in a timely manner is limited by the sheer volumes of data collected. In this study, we aim to evaluate the feasibility of using multiclass classification to automate the identification of patient safety incidents in hospitals...
