Subtle impairments of perceptual-motor function and well-being are detectable among military cadets and college athletes with self-reported history of concussion.

Introduction: A lack of obvious long-term effects of concussion on standard clinical measures of behavioral performance capabilities does not preclude the existence of subtle neural processing impairments that appear to be linked to elevated risk for subsequent concussion occurrence, and which may be associated with greater susceptibility to progressive neurodegenerative processes. The purpose of this observational cohort study was to assess virtual reality motor response variability and survey responses as possible indicators of suboptimal brain function among military cadets and college athletes with self-reported history of concussion (HxC).

Methods: The cohort comprised 75 college students (20.

Athletic Trainers' Shared Professional Values: A Report From the National Athletic Trainers' Association Professional Responsibility in Athletic Training Committee.

Context: Professional values (PVs) of health care providers influence their professional decisions and behaviors. Athletic training is one of the remaining health professions without established shared PVs. Commitment to shared PVs, also known as core values, prompts good and right behavior by guiding moral and ethical judgment and professional decision-making.

A Neuro-Integrative Assessment of Perceptual-Motor Performance and Wellness in ROTC Cadets.

Resting heart rate variability (HRV) may be a useful index of both brain-based executive function and general health. Our purpose in this study was to quantify relationships among HRV, perceptual-motor performance metrics, and wellness survey responses. A cohort of 32 male Reserve Officer Training Corp (ROTC) cadets completed a dual-task upper extremity reaction time (UERT) test, two tests of whole-body reactive agility, and a 10-item wellness survey that produced a 0-100 Overall Wellness Index (OWI).

Mitigating Sports Injury Risks Using Internet of Things and Analytics Approaches.

Sport injuries restrict participation, impose a substantial economic burden, and can have persisting adverse effects on health-related quality of life. The effective use of Internet of Things (IoT), when combined with analytics approaches, can improve player safety through identification of injury risk factors that can be addressed by targeted risk reduction training activities. Use of IoT devices can facilitate highly efficient quantification of relevant functional capabilities prior to sport participation, which could substantially advance the prevailing sport injury management paradigm.

Longitudinal regret after treatment for low- and intermediate-risk prostate cancer.

Background: Prostate cancer patients diagnosed with low- and intermediate-risk disease have several treatment options. Decisional regret after treatment is a concern, especially when poor oncologic outcomes or declines in health-related quality of life (HRQoL) occur. This study assessed determinants of longitudinal decisional regret in prostate cancer patients attending a multidisciplinary clinic and treated with radical prostatectomy (RP), external beam radiation therapy (EBRT), brachytherapy (BT), or active surveillance (AS).

Posttraumatic Stress Disorder, Depression, and Other Comorbidities: Clinical and Systems Approaches to Diagnostic Uncertainties.

Overlap in the clinical presentation and significant rates of comorbidity complicate effective management of depression and PTSD, each presenting major health burdens for veterans and active-duty service members.

Utilization of Practice Session Average Inertial Load to Quantify College Football Injury Risk.

Wilkerson, GB, Gupta, A, Allen, JR, Keith, CM, and Colston, MA. Utilization of practice session average inertial load to quantify college football injury risk. J Strength Cond Res 30(9): 2369-2374, 2016-Relatively few studies have investigated the potential injury prevention value of data derived from recently developed wearable technology for measurement of body mass accelerations during the performance of sport-related activities.

A prospective cohort study of treatment decision-making for prostate cancer following participation in a multidisciplinary clinic.

Background: Patients diagnosed with prostate cancer (PCa) are presented with several treatment options of similar efficacy but varying side effects. Understanding how and why patients make their treatment decisions, as well as the effect of treatment choice on long-term outcomes, is critical to ensuring effective, patient-centered care. This study examined treatment decision-making in a racially diverse, equal-access, contemporary cohort of patients with PCa counseled on treatment options at a multidisciplinary clinic.

Setting: National Collegiate Athletic Association Division I athletic program.

A Refined Prediction Model for Core and Lower Extremity Sprains and Strains Among Collegiate Football Players.

Context: Researchers have identified high exposure to game conditions, low back dysfunction, and poor endurance of the core musculature as strong predictors for the occurrence of sprains and strains among collegiate football players.

Objective: To refine a previously developed injury-prediction model through analysis of 3 consecutive seasons of data.

Design: Cohort study.

Genome analysis shows a common evolutionary origin for the dominant strains of Mycobacterium tuberculosis in a UK South Asian community.

We have investigated the Mycobacterium tuberculosis strain types present in the South Asian population of the UK, in which tuberculosis is particularly prevalent. In contrast to the widespread Beijing strains which have the variable number tandem repeats (VNTR) profile 42435, isolates with the VNTR profile 42235, jointly with 02335 or 42234 profiles, appear more frequently in tuberculosis patients of South Asian ethnic origin (SA-strains) in the UK than in any other ethnic group. Using microarray-based comparative genomics to distinguish total or partially deleted genes, we found that three of the common deleted regions in the SA-strains were identical to some deleted genes in the strain CH, which caused an outbreak among South Asian patients in Leicester in 2001 but were different from genomic deletions found in Beijing/W strains.

Sagittal lumbar spine position during standing, walking, and running at various gradients.

Context: Motion in the lumbar spine during certain physical activities may exceed tissue homeostasis, leading to low back pain. Previous authors have assessed sagittal motion of the lumbar spine during walking; however, limited attention has been focused on changes in spine position with walking or running on different surface gradients.

Objective: To investigate lumbar spine sagittal position during standing, walking, and running on level, uphill, and downhill surfaces.

Induction of high levels of protective immunity in mice after vaccination using dendritic cells infected with auxotrophic mutants of Mycobacterium tuberculosis.

Adoptively transferred dendritic cells presenting antigens derived from different pathogens have been shown to elicit specific T cell responses and to induce protective antibacterial immunity. We describe here the induction of high levels of protective immunity in mice using dendritic cells infected with auxotrophic mutants of Mycobacterium tuberculosis. We provide evidence that protection is superior to BCG and that it is associated with increased priming of CD4+ and CD8+ T cells specific for mycobacterial antigens.

Therapeutic efficacy of high-dose intravenous immunoglobulin in Mycobacterium tuberculosis infection in mice.

Intravenous immunoglobulin (IVIg) is used to treat patients with primary antibody deficiencies and, at high doses, to treat a range of autoimmune and inflammatory disorders. With high-dose IVIg (hdIVIg), immunomodulatory mechanisms act on a range of cells, including T cells, B cells, and dendritic cells. Here, we demonstrate that the treatment of M.

Deletion of the Mycobacterium tuberculosis pknH gene confers a higher bacillary load during the chronic phase of infection in BALB/c mice.

The role of the serine/threonine kinase PknH in the physiology and virulence of Mycobacterium tuberculosis was assessed by the construction of a pknH deletion mutant. Deletion of the pknH gene did not affect sensitivity to the antimycobacterial drug ethambutol, although it was previously thought to be involved in regulating expression of emb genes encoding arabinosyl transferases, the targets of ethambutol. Nevertheless, transcription analyses revealed that genes associated with mycobacterial cell wall component synthesis, such as emb and ini operons, are downstream substrates of the PknH signaling cascade.

An ABC transporter containing a forkhead-associated domain interacts with a serine-threonine protein kinase and is required for growth of Mycobacterium tuberculosis in mice.

Forkhead-associated (FHA) domains are modular phosphopeptide recognition motifs with a striking preference for phosphothreonine-containing epitopes. FHA domains have been best characterized in eukaryotic signaling pathways but have been identified in six proteins in Mycobacterium tuberculosis, the causative organism of tuberculosis. One of these, coded by gene Rv1747, is an ABC transporter and the only one to contain two such modules.

A member of the cAMP receptor protein family of transcription regulators in Mycobacterium tuberculosis is required for virulence in mice and controls transcription of the rpfA gene coding for a resuscitation promoting factor.

Deletion of gene Rv3676 in Mycobacterium tuberculosis coding for a transcription factor belonging to the cAMP receptor protein (CRP) family caused growth defects in laboratory medium, in bone marrow-derived macrophages and in a mouse model of tuberculosis. Transcript profiling of M. tuberculosis grown in vitro identified 16 genes with significantly altered expression in the mutant compared with the wild type.

The mechanism of upstream activation in the rrnB operon of Mycobacterium smegmatis is different from the Escherichia coli paradigm.

Mycobacteria are slow-growing bacteria with a generation time of from 2-3 h up to several weeks. Consistent with the low growth rate, mycobacterial species have a maximum of two rRNA operons, rrnA and rrnB. The rrnA operon is present in all mycobacteria and has between two and five promoters, depending on species, whereas the rrnB operon, with a single promoter, is only found in some of the faster-growing species.

Gene expression in human macrophages infected with dengue virus serotype-2.

Infection by any of the four serotypes of dengue viruses (DEN-1, -2, -3 and -4) may result in either a relatively benign fever, called dengue fever (DF), a fatal disease, such as dengue haemorrhagic fever (DHF) or dengue shock syndrome (DSS). Several lines of evidence suggest that soluble immune response mediators may be involved in the severity of dengue infections. For instance, elevated seric levels of IL-8 are a common feature in DHF patients.

A heterologous DNA priming-Mycobacterium bovis BCG boosting immunization strategy using mycobacterial Hsp70, Hsp65, and Apa antigens improves protection against tuberculosis in mice.

Tuberculosis is responsible for >2 million deaths a year, and the number of new cases is rising worldwide. DNA vaccination combined with Mycobacterium bovis bacillus Calmette Guerin (BCG) represents a potential strategy for prevention of this disease. Here, we used a heterologous prime-boost immunization approach using a combination of DNA plasmids and BCG in order to improve the efficacy of vaccination against Mycobacterium tuberculosis infection in mice.
