Muscle dysmorphia (MD) is characterized by the pathological pursuit of muscularity and leanness, which includes eating- and exercise-related practices. The aim of this cross-sectional study was to identify correlations of MD symptomatology in natural bodybuilders. An online survey assessing diet, supplementation and training practices, and MD and eating disorder symptoms was completed by male bodybuilders with recent experience competing in a drug-tested competition. Sixty participants (age 29.6±7.1 years) completed the survey...

PURPOSE: Familial cerebral cavernous malformation (CCM) patients present with multiple lesions that can grow both in number and size over time and are reliably detected on susceptibility-weighted imaging (SWI). Manual counting of lesions is arduous and subject to high variability. We aimed to develop an automated algorithm for counting CCM microbleeds (lesions <5 mm in diameter) on SWI images. METHODS: Fifty-seven familial CCM type-1 patients were included in this institutional review board-approved study...

Genomic prediction was evaluated in German winter barley breeding lines. In this material, prediction ability is strongly influenced by population structure and main determinant of prediction ability is the close genetic relatedness of the breeding material. To ensure breeding progress under changing environmental conditions the implementation and evaluation of new breeding methods is of crucial importance. Modern breeding approaches like genomic selection may significantly accelerate breeding progress. We assessed the potential of genomic prediction in a training population of 750 genotypes, consisting of multiple six-rowed winter barley (Hordeum vulgare L...

Physical inactivity and dyslipidemia are considered risk factors for cardiovascular diseases. There are few studies evaluating the effects of physical exercise in small-caliber artery in a model that mimics familial hypercholesterolemia. The aim of this study was to examine the effect of exercise training, at moderate intensity, on metabolic parameters and iliac artery responsiveness in LDL(-/-) mice. Sedentary (SD) and trained (TR) mice performed AET (5 days/week, 60 minutes/day at 60-70% of maximum speed) during 8 weeks...

[Purpose] To report an adolescent male basketball player with nonhealing stress fractures of the foot and discuss the probable factors. [Subject and Methods] A 13-year-old basketball player presented with right foot pain. He had been playing basketball for three years and practicing 5 days/week. He denied any increase in daily training intensity. Magnetic resonance imaging confirmed stress fractures of the cuboid and cuneiform, with mild edema of the soft tissues between the tarsal bones and tenosynovitis of the flexor hallucis and flexor digitorum longi...

[Purpose] This study aimed to investigate the effects of training involving compelled weight shift on the paretic lower limb on gait parameters and plantar pressure distribution in patients with stroke. [Subjects and Methods] Forty-five stroke patients participated in the study and were randomly divided into: group with a 5-mm lift on the non-paretic side for constrained weight shift training (5: constrained weight shift training) (n=15); group with a 10-mm lift on the non-paretic side for constrained weight shift training (10: constrained weight shift training) (n=15); or the control group (n=15)...

BACKGROUND: The imaging assessment of paraspinal muscle morphology and fatty infiltration has gained considerable attention in the past decades, with reports suggesting an association between muscle degenerative changes and low back pain (LBP). To date, qualitative and quantitative approaches have been used to assess paraspinal muscle composition. Though highly reliable, manual thresholding techniques are time consuming and not always feasible in a clinical setting. The tedious and rater-dependent nature of such manual thresholding techniques provides the impetus for the development of automated or semi-automated segmentation methods...

PURPOSE: To investigate the influence of daily and exponentially-weighted moving training loads on subsequent night-time sleep. METHODS: Sleep of fourteen professional rugby league athletes competing in the National Rugby League competition was recorded using wristwatch actigraphy. Physical demands were quantified using GPS technology, including total distance (TD), high-speed distance (HSD), acceleration/deceleration load (SumAccDec; AU), and sRPE (AU). Linear mixed models determined effects of acute (daily) and sub-acute (three- and seven-day) exponentially-weighted moving averages (EWMA) on sleep...

Yan Xu, Jing Yang, Shuiming Zhong
The purpose of supervised learning with temporal encoding for spiking neurons is to make the neurons emit a specific spike train encoded by precise firing times of spikes. The gradient-descent-based (GDB) learning methods are widely used and verified in the current research. Although the existing GDB multi-spike learning (or spike sequence learning) methods have good performance, they work in an offline manner and still have some limitations. This paper proposes an online GDB spike sequence learning method for spiking neurons that is based on the online adjustment mechanism of real biological neuron synapses...

Prediction accuracy of a cure model when it is used to predict the cure probability of a patient is an important but not well-addressed issue in survival analysis. We propose a method to assess the prediction accuracy of a mixture cure model in predicting cure probability based on inverse probability of censoring weights to incorporate the censoring and latent cure status in the data. The inverse probability of censoring weight-adjusted estimator is shown to be consistent for the true expected prediction error for cure probability...

BACKGROUND: Studies of the body size and proportions of athletes have a long history. Comparisons of athletes within specific sports across time, though not extensive, indicate both positive and negative trends. OBJECTIVE: To evaluate secular variation in heights and weights of male youth soccer players reported in studies between 1978 and 2015. METHODS: Reported mean ages, heights, and weights of male soccer players 9-18 years of age were extracted from the literature and grouped into two intervals: 1978-99 and 2000-15...

BACKGROUND: In this study, we evaluated the ability of radiomic textural analysis of intratumoral and peritumoral regions on pretreatment breast cancer dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to predict pathological complete response (pCR) to neoadjuvant chemotherapy (NAC). METHODS: A total of 117 patients who had received NAC were retrospectively analyzed. Within the intratumoral and peritumoral regions of T1-weighted contrast-enhanced MRI scans, a total of 99 radiomic textural features were computed at multiple phases...

BACKGROUND: A paucity of research currently exists for upper extremity return to sport testing. The Upper Quarter Y-Balance Test (YBT-UQ) is a clinical test of closed kinetic chain performance with demonstrated reliability. Prior investigations of the YBT-UQ were conducted with individuals in a resting state and no comparison to performance in a fatigued state has been conducted. PURPOSE: To examine the effect of upper extremity fatigue on the performance of the YBT-UQ in recreational weightlifters...

BACKGROUND: Bystander cardiopulmonary resuscitation (CPR) is associated with increased survival from cardiac arrest, yet bystander CPR rates are low in many communities. The overall prevalence of CPR training in the United States and associated individual-level disparities are unknown. We sought to measure the national prevalence of CPR training and hypothesized that older age and lower socioeconomic status would be independently associated with a lower likelihood of CPR training. METHODS AND RESULTS: We administered a cross-sectional telephone survey to a nationally representative adult sample...
