Kyle R Barnes, Jessica N Janecke
BACKGROUND: As a way to train at faster running speeds, add training volume, prevent injury, or rehabilitate after an injury, lower-body positive pressure treadmills (LBPPT) have become increasingly commonplace among athletes. However, there are conflicting evidence and a paucity of data describing the physiological and biomechanical responses to LBPPT running in highly trained or elite caliber runners at the running speeds they habitually train at, which are considerably faster than those of recreational runners...

In addition to different injuries, infections are the most common reason for giving up training altogether or reducing its volume and intensity, as well as a lack of opportunities to participate in sports competitions. Nowadays, a slow but constant re-emergence of pertussis, especially among teenagers and young adults, including athletes, can be observed. This paper describes an outbreak of pertussis among professional Polish shooters, focusing on the transmission of Bordetella pertussis infection between members of the national team, its influence on performance capacity and adverse event analysis...

BACKGROUND AND OBJECTIVE: We address the problem of automated outcome assessment in a virtual reality (VR) simulator for endodontic surgery. Outcome assessment is an essential component of any system that provides formative feedback, which requires assessing the outcome, relating it to the procedure, and communicating in a language natural to dental students. This study takes a first step toward automated generation of such comprehensive feedback. METHODS: Virtual reference templates are computed based on tooth anatomy and the outcome is assessed with a 3D score cube volume which consists of voxel-level non-linear weighted scores based on the templates...

INTRODUCTION: The use of novel bioengineer treatment techniques such as Autologous Tenocyte Implantation (ATI) have shown promising improvements in both pain ratings and functional outcomes in elbow, gluteal and shoulder tendon pathology. This case will review the injury timeline of ATI intervention in an elite male swimmer with subscapularis tendon pathology and investigate whether ATI has a concomitant healing effect associated with improved functional outcomes. METHODS: A palmaris longus tendon biopsy was performed and cells were expanded by in-vitro culture...

Adaptations to long-term exercise training in type 1 diabetes are sparsely studied. We examined the effects of a 1-year individualized training intervention on cardiorespiratory fitness, exercise-induced active muscle deoxygenation, and glycemic control in adults with and without type 1 diabetes. Eight men with type 1 diabetes (T1D) and eight healthy men (CON) matched for age, anthropometry, and peak pulmonary O2 uptake (V̇O2peak), completed a 1-year individualized training intervention in an unsupervised real-world setting...

In mild cognitive impairment (MCI), small benefits from cognitive training were observed for memory functions but there appears to be great variability in the response to treatment. Our study aimed to improve the characterization and selection of those participants who will benefit from cognitive intervention. We evaluated the predictive value of disease-specific biological factors for the outcome after cognitive training in MCI (n = 25) and also considered motivation of the participants. We compared the results of the cognitive intervention group with two independent control groups of MCI patients (local memory clinic, n = 20; ADNI cohort, n = 302)...

Impedance cardiography is a low-cost noninvasive technique, based on monitoring of the thoracic impedance, for estimation of stroke volume (SV). Impedance cardiogram (ICG) is the negative of the first derivative of the impedance signal. A technique for beat-to-beat SV estimation using impedance cardiography and artificial neural network (ANN) is proposed. A three-layer feed-forward ANN with error back-propagation algorithm is optimized by examining the effects of number of neurons in the hidden layer, activation function, training algorithm, and set of input parameters...

REVIEW
Ashraf Fayad, Sasha K Shillcutt
PURPOSE: The use of transesophageal echocardiography (TEE) has evolved to include patients undergoing high-risk non-cardiac procedures and patients with significant cardiac disease undergoing non-cardiac surgery. Implementation of basic TEE education in training programs has increased across a broad spectrum of procedures in the perioperative arena. This paper describes the use of perioperative TEE in non-cardiac surgery and provides an overview of the basic TEE examination. PRINCIPAL FINDINGS: Perioperative TEE is used to monitor hemodynamic parameters in non-cardiac procedures where there is a high risk of hemodynamic instability...

Increased attentional bias to threat has been identified as a causal mechanism in the development of anxiety. As such, attention bias modification (ABM) was conceived as a treatment option where anxiety is alleviated through a computerized cognitive training regimen that reduces an individual's attentional bias to threat. Although ABM appears to be a promising treatment option for anxiety, the mechanism of action by which the treatment is effective is unknown. We hypothesize that effective ABM treatment is associated with neuroplasticity-related structural changes in an extended amygdala - prefrontal cortex network that can be detected with standard T1-weighted magnetic resonance imaging (MRI)...

Exercise training can affect the breast tumor growth. We hypothesized that exercise training may reduce breast tumor growth by inducing Oxytocin (OT) secretion and its related signaling pathways such as PI3K/AKT and ERK. Therefore fifty-six BALB/c mice were equally divided into seven groups to study the effects of OT and atosiban (an oxytocin receptor antagonist) together with the interval exercise training on breast tumor growth, as well as tumor related signaling pathways including PI3K/AKT and ERK. Animal weight, OT plasma level, tumor weight and volume measured at the end of study...

Exercise therapy is a promising nonpharmacological therapy in people with multiple sclerosis (MS). Although exercise training may induce a transient worsening of symptoms in some MS patients, it is generally considered safe and does not increase the risk of relapses. Exercise training can lead to clinically relevant improvements in physical function, but should be considered an adjunct to specific task-based training. Exercise has also shown positive effects on the brain, including improvements in brain volume and cognition...

Exercise-induced bronchoconstriction, associated or not with asthma, describes a transient limitation of airflow in the airways occurring during or after physical activity, regardless of age or training. Bronchoconstriction on exertion is principally induced by thermal and fluid losses of the bronchial mucosa by hyperventilation of large air volumes. Respiratory symptoms are variable and not specific. Among bronchial provocation test, eucapnic voluntary hyperventilation owns the best sensitivity and specificity in the diagnosis of exercise-induced bronchoconstriction...

BACKGROUND: General surgery residents are increasingly pursuing sub-specialty training in colorectal (CR) surgery. However, the majority of operations performed by CR surgeons are also performed by general surgeons. This study aimed to assess in-hospital mortality stratified by CR training status after adjusting for surgeon and hospital volume. METHODS: The Statewide Planning and Research Cooperative system database was used to identify all patients who underwent colectomy/proctectomy from January 1, 2000, to December 31, 2014, in the state of New York...

Although neurogastroenterology and motility (NGM) disorders affect 50% of patients seen in clinics, many gastroenterologists receive limited NGM training. One-month apprenticeship-based NGM training has been provided at ten centers in the USA for a decade, however, outcomes of this training are unclear. Our goal was to describe the effectiveness of this program from a trainees perspective. Areas Covered: We describe the training model, learning experiences, and outcomes of one-month apprenticeship-based training in NGM at a center of excellence, using a detailed individual observer account and data from 12 consecutive trainees that completed the program...

Spectral-domain optical coherence tomography (SDOCT), in addition to its routine clinical use in the diagnosis of ocular diseases, has begun to find increasing use in animal studies. Animal models are frequently used to study disease mechanisms as well as to test drug efficacy. In particular, SDOCT provides the ability to study animals longitudinally and non-invasively over long periods of time. However, the lack of anatomical landmarks makes the longitudinal scan acquisition prone to inconsistencies in orientation...
