Accuracy of self-reported foot strike pattern detection among endurance runners.

Introduction: Foot strike pattern is often associated with running related injury and the focus of training and rehabilitation for athletes. The ability to modify foot strike pattern depends on awareness of foot strike pattern before being able to attempt change the pattern. Accurate foot strike pattern detection may help prevent running related injury (RRI) and facilitate gait modifications and shoe transitions.

The impact of body mass index on rehabilitation outcomes after lower limb amputation.

Purpose: To determine the effect of obesity on physical function and clinical outcome measures in patients who received inpatient rehabilitation services for lower extremity amputation.

Methods: A retrospective review was performed on patients with lower extremity amputation (n = 951). Patients were stratified into five categories adjusted for limb loss mass across different levels of healthy body mass index (BMI), overweight, and obesity.

To be aware or not aware: Do intrusions with and without meta-awareness differ?

People sometimes re-experience traumatic events via intrusive memories that spontaneously and unintentionally intrude into consciousness (i.e., intrusions).

Personalizing cognitive processing therapy with a case formulation approach to intentionally target impairment in psychosocial functioning associated with PTSD.

Posttraumatic stress disorder (PTSD) is a debilitating condition often accompanied by significant functional impairments affecting quality of life and well-being. While Cognitive Processing Therapy (CPT) is a leading, evidence-based psychotherapy for PTSD, demonstrating substantial efficacy in core symptom reduction, its impact on psychosocial functioning is less well-established. The Personalizing Cognitive Processing Therapy with a Case Formulation Approach (Personalizing Approaches to Therapy: PATh) study aims to enhance CPT by explicitly targeting functional impairments and idiosyncratic challenges to optimal therapy outcomes (COTOs), comparing its efficacy against standard CPT in improving psychosocial functioning, quality of life, well-being, and core PTSD and depression symptoms.

Protecting Emergency Responders with Evidence-Based Interventions (PEREI): protocol for a randomized controlled trial for early career emergency responders, significant others, and supervisors.

Emergency service personnel perform roles associated with high levels of trauma exposure and stress, and not surprisingly experience greater risk for poor mental health including posttraumatic stress disorder (PTSD), depression, anxiety, and substance use relative to the general population. Although programs exist to minimise the risk of developing mental health problems, their efficacy to date has been limited or untested. We will test the efficacy of the three programs which form PEREI: Protecting Emergency Responders with Evidence-Based Interventions.

State of the Science of Cognitive Processing Therapy.

This state of the science review provides an overview of the history and findings of cognitive processing therapy (CPT), one of the most recommended treatments for posttraumatic stress disorder, acute stress disorder, and comorbid conditions. After an introduction to CPT and the randomized controlled trials that have been conducted, the effects of CPT on comorbid conditions are reviewed, as well as new combination treatments. Cognitive mediators of change are described.

Switching of electrochemical selectivity due to plasmonic field-induced dissociation.

Electrochemical reactivity is known to be dictated by the structure and composition of the electrocatalyst-electrolyte interface. Here, we show that optically generated electric fields at this interface can influence electrochemical reactivity insofar as to completely switch reaction selectivity. We study an electrocatalyst composed of gold-copper alloy nanoparticles known to be active toward the reduction of CO to CO.

Pathophysiologic abnormalities in transgenic mice carrying the Alzheimer disease PSEN1 Δ440 mutation.

Mutations in PSEN1 were first discovered as a cause of Alzheimer's disease (AD) in 1995, yet the mechanism(s) by which the mutations cause disease still remains unknown. The generation of novel mouse models assessing the effects of different mutations could aid in this endeavor. Here we report on transgenic mouse lines made with the Δ440 PSEN1 mutation that causes AD with parkinsonism:- two expressing the un-tagged human protein and two expressing a HA-tagged version.

Mechanisms of autophagy-lysosome dysfunction in neurodegenerative diseases.

Autophagy is a lysosome-based degradative process used to recycle obsolete cellular constituents and eliminate damaged organelles and aggregate-prone proteins. Their postmitotic nature and extremely polarized morphologies make neurons particularly vulnerable to disruptions caused by autophagy-lysosomal defects, especially as the brain ages. Consequently, mutations in genes regulating autophagy and lysosomal functions cause a wide range of neurodegenerative diseases.

A retrospective cross-sectional study of risk factors for communicable disease diagnoses among refugees in mainland Greek camps, 2016-2017.

Communicable disease risk is high in refugee camps and reception centers. To better understand the risks for communicable disease diagnoses among refugees and asylum seekers, this study assesses individual- and camp-level risk factors among individuals utilizing Médecins du Monde clinics in four large refugee camps-Elliniko, Malakasa, Koutsochero, and Raidestos-on mainland Greece between July 2016 and May 2017. Descriptive statistics are reported for the demographic characteristics of the study population and for communicable disease burdens within the four camps-Elliniko, Malakasa, Raidestos, and Koutsochero.

Walking the line between fidelity and flexibility: A conceptual review of personalized approaches to manualized treatments for posttraumatic stress disorder.

The heterogeneity of the core symptoms of posttraumatic stress disorder (PTSD), high rates of comorbid mental and physical health conditions, and substantial impact of the disorder on functioning and well-being contribute to complex clinical presentations that can be challenging to treat. Despite these challenges, there are excellent manualized treatments for PTSD with significant empirical support. Although the success of frontline treatments for PTSD is evident, there remains room for improvement as indicated by suboptimal response and attrition rates.

Gait signatures of endurance runners with low back pain: A case controlled cross sectional study.

Background: Low back pain (LBP) is an understudied condition among runners, and it is unclear what biomechanical features could be targeted for gait retraining to mitigate pain.

Research Question: How do running biomechanics differ between healthy individuals and those with running-related LBP?

Methods: This was a case-controlled, comparative study design of community runners: running-related LBP (n=52) and healthy controls (n=52). All runners completed running history forms and performed a 3-dimensional gait analysis.

Pathobiology of the autophagy-lysosomal pathway in the Huntington's disease brain.

Accumulated levels of mutant huntingtin protein (mHTT) and its fragments are considered contributors to the pathogenesis of Huntington's disease (HD). Although lowering mHTT by stimulating autophagy has been considered a possible therapeutic strategy, the role and competence of autophagy-lysosomal pathway (ALP) during HD progression in the human disease remains largely unknown. Here, we used multiplex confocal and ultrastructural immunocytochemical analyses of ALP functional markers in relation to mHTT aggresome pathology in striatum and the less affected cortex of HD brains staged from HD2 to HD4 by Vonsattel neuropathological criteria compared to controls.

mTOR inhibition in Q175 Huntington's disease model mice facilitates neuronal autophagy and mutant huntingtin clearance.

Huntington's disease (HD) is caused by expansion of the polyglutamine stretch in huntingtin protein (HTT) resulting in hallmark aggresomes/inclusion bodies (IBs) composed of mutant huntingtin protein (mHTT) and its fragments. Stimulating autophagy to enhance mHTT clearance is considered a potential therapeutic strategy for HD. Our recent evaluation of the autophagic-lysosomal pathway (ALP) in human HD brain reveals upregulated lysosomal biogenesis and relatively normal autophagy flux in early Vonsattel grade brains, but impaired autolysosome clearance in late grade brains, suggesting that autophagy stimulation could have therapeutic benefits as an earlier clinical intervention.

Efficacy of two brief trauma-focussed writing interventions in comparison to positive experiences writing: A randomized controlled trial.

Background: There is emerging literature regarding the efficacy of trauma-focussed writing therapies (TF-WTs) for posttraumatic stress. Such therapies have the potential to reduce posttraumatic stress symptoms (PTSS) in a brief time frame and can be delivered remotely. There remains a need for further research assessing the efficacy of different types of TF-WTs, as well comparing them to alternative control conditions not previously assessed.
