Mortality Among Veterans Following Traumatic Brain Injury: A Veterans Administration Traumatic Brain Injury Model System Study.

Few studies have examined long-term mortality following traumatic brain injury (TBI) in a military population. This is a secondary analysis of a prospective, longitudinal study that examines long-term mortality (up to 10 years) post-TBI, including analyses of life expectancy, causes of death, and risk factors for death in service members and veterans (SM/V) who survived the acute TBI and inpatient rehabilitation. Among 922 participants in the study, the mortality rate was 8.

A systematic critical appraisal of clinical practice guidelines of antithrombotic agents in gastrointestinal endoscopy using the AGREE II tool.

Background And Aim: The quality of clinical practice guidelines (CPGs) for the management of antithrombotic agents in patients undergoing gastrointestinal (GI) endoscopy has not been systematically appraised. The goal of this study was to evaluate the methodological quality of CPGs for the management of antithrombotic agents in periendoscopic period published within last 6 years.

Methods: A systematic search of PubMed and Embase databases was performed to identify eligible CPGs published between January 1, 2016, and April 14, 2022, addressing the management of antithrombotic agents in the periendoscopic period.

Transfemoral interface considerations: A clinical consensus practice guideline.

Background: Although there have been a number of studies exploring the impact and efficacy of transfemoral prosthetic components such as knee and foot mechanisms, the empirical evidence surrounding transfemoral prosthetic interface considerations is limited. This constitutes a substantial void for practicing clinicians seeking to apply best practices for patients who use transfemoral prostheses. Recent years have seen increased production and availability of clinical practice guidelines germane to prosthetic rehabilitation.

Inhibition of Epidermal Growth Factor Receptor Signaling by Antisense Oligonucleotides as a Novel Approach to Epidermal Growth Factor Receptor Inhibition.

We report a novel method to inhibit epidermal growth factor receptor (EGFR) signaling using custom morpholino antisense oligonucleotides (ASOs) to drive expression of dominant negative mRNA isoforms of EGFR by ASO-induced exon skipping within the transmembrane (16) or tyrosine kinase domains (18 and 21). ASO formulations induced >95% exon skipping in several models of nonsmall cell lung cancer (NSCLC) and were comparable in efficacy to erlotinib in reducing colony formation, cell viability, and migration in EGFR mutant NSCLC (PC9). However, unlike erlotinib, ASOs maintained their efficacy in both erlotinib-resistant subclones (PC9-GR) and wild-type overexpressing EGFR models (H292), in which erlotinib had no significant effect.

Prefrontal transcranial magnetic stimulation for depression in US military veterans - A naturalistic cohort study in the veterans health administration.

Background: Repetitive transcranial magnetic stimulation (TMS) is an evidence-based treatment for pharmacoresistant major depressive disorder (MDD), however, the evidence in veterans has been mixed. To this end, VA implemented a nationwide TMS program that included evaluating clinical outcomes within a naturalistic design. TMS was hypothesized to be safe and provide clinically meaningful reductions in MDD and posttraumatic stress disorder (PTSD) symptoms.

Volumetric histological characterization of optic nerve degeneration using tissue clearing: literature review and practical study.

Tissue clearing technologies can greatly improve the depth and accuracy with which the three-dimensional structure of tissues, especially those of th*-e nervous system, can be visualized. A review of the present literature suggests that the growing diversity and sophistication of various approaches have contributed to the expansion of this method to a greater variety of tissue types, experimental conditions, and imaging modalities. In the proof-of-concept study presented in this paper, a simplified and modified version of the tissue clearing method CUBIC (clear, unobstructed brain imaging cocktails and computational analysis) was used in conjunction with fluorescent staining and immunohistochemistry to illustrate the three-dimensional structure and molecular characteristics of inflammatory and degenerative activity in the mouse optic nerve.

Mitochondrial CHCHD2: Disease-Associated Mutations, Physiological Functions, and Current Animal Models.

Rare mutations in the mitochondrial protein coiled-coil-helix-coiled-coil-helix domain containing 2 (CHCHD2) are associated with Parkinson's disease (PD) and other Lewy body disorders. CHCHD2 is a bi-organellar mediator of oxidative phosphorylation, playing crucial roles in regulating electron flow in the mitochondrial electron transport chain and acting as a nuclear transcription factor for a cytochrome c oxidase subunit (COX4I2) and itself in response to hypoxic stress. CHCHD2 also regulates cell migration and differentiation, mitochondrial cristae structure, and apoptosis.

Auditory N2 Correlates of Treatment Response in Posttraumatic Stress Disorder.

Emotional processing and cognitive control are implicated as being dysfunctional in posttraumatic stress disorder (PTSD) and targeted in cognitive processing therapy (CPT), a trauma-focused treatment for PTSD. The N2 event-related potential has been interpreted in the context of emotional processing and cognitive control. In this analysis of secondary outcome measures from a randomized controlled trial, we investigated the latency and amplitude changes of the N2 in responses to task-relevant target tones and task-irrelevant distractor sounds (e.

SSH1 impedes SQSTM1/p62 flux and MAPT/Tau clearance independent of CFL (cofilin) activation.

Accumulation of toxic protein assemblies and damaged mitochondria are key features of neurodegenerative diseases, which arise in large part from clearance defects in the Macroautophagy/autophagy-lysosome system. The autophagy cargo receptor SQSTM1/p62 plays a major role in the clearance of ubiquitinated cargo through Ser403 phosphorylation by multiple kinases. However, no phosphatase is known to physiologically dephosphorylate SQSTM1 on this activating residue.

Impact of Comorbid PTSD on Outcome of Repetitive Transcranial Magnetic Stimulation (TMS) for Veterans With Depression.

Objective: A recent randomized controlled trial of repetitive transcranial magnetic stimulation (TMS) for major depressive disorder (MDD) in veterans raised the question of whether comorbid posttraumatic stress disorder (PTSD) negatively impacted the outcome of TMS in veterans. To address this, a quality database was analyzed to compare outcomes of MDD treated with TMS in veterans with and without comorbid PTSD.

Methods: The clinical outcomes of all consecutive veterans with MDD treated with TMS at the James A.

CHCHD10-regulated OPA1-mitofilin complex mediates TDP-43-induced mitochondrial phenotypes associated with frontotemporal dementia.

Mutations in CHCHD10, a gene coding for a mitochondrial protein, are implicated in ALS-FTD spectrum disorders, which are pathologically characterized by transactive response DNA binding protein 43 kDa (TDP-43) accumulation. While both TDP-43 and CHCHD10 mutations drive mitochondrial pathogenesis, mechanisms underlying such phenotypes are unclear. Moreover, despite the disruption of the mitochondrial mitofilin protein complex at cristae junctions in patient fibroblasts bearing the CHCHD10 mutation, the role of CHCHD10 variants in mitofilin-associated protein complexes in brain has not been examined.

Quantification of Equine Sacral and Iliac Motion During Application of Manual Forces and Comparison Between Motion Capture With Skin-Mounted and Bone-Fixated Sensors.

Diagnosis of sacroiliac dysfunction in horses includes manual motion palpation of the equine ilium and sacrum. Motion of the ilium and sacrum during manual force application to the equine pelvis has been measured previously in vitro. The aim of this study was to measure the amount and direction of motion in vivo, including comparison of bone-fixated and skin-mounted inertial sensors.

One hertz versus ten hertz repetitive TMS treatment of PTSD: A randomized clinical trial.

The purpose of this trial was to test whether right prefrontal cortex 1 Hz versus 10 Hz rTMS provides a significantly greater improvement in PTSD symptoms and/or function. Veterans 18 to 50 years of age suffering from PTSD were randomized to right prefrontal 1 Hz rTMS [2400 pulses/session] versus right prefrontal 10 Hz rTMS [2400 pulses/session]. The treatments were performed 5 days a week for 6 weeks with a 3-week taper using the NeuroStar system.

Vision impairment after traumatic brain injury: present knowledge and future directions.

Traumatic brain injury (TBI) is a major cause of mortality and morbidity in the USA as well as in the world. As a result of TBI, the visual system is also affected often causing complete or partial visual loss, which in turn affects the quality of life. It may also lead to ocular motor dysfunction, defective accommodation, and impaired visual perception.

Low back pain in persons with lower extremity amputation: a systematic review of the literature.

Background Context: Lower extremity amputation (LEA) is associated with an elevated risk for development and progression of secondary health conditions. Low back pain (LBP) is one such condition adversely affecting function, independence, and quality of life.

Purpose: The purpose of this study was to systematically review the literature to determine the strength of evidence relating the presence and severity of LBP secondary to LEA, thereby supporting the formulation of empirical evidence statements (EESs) to guide practice and future research.

Clinical Repetitive Transcranial Magnetic Stimulation for Posttraumatic Stress Disorder, Generalized Anxiety Disorder, and Bipolar Disorder.

Repetitive transcranial magnetic stimulation (rTMS) is being investigated for psychiatric disorders such as posttraumatic stress disorder (PTSD), generalized anxiety disorder (GAD), and both phases of bipolar disorder. Case series, open trials, and randomized controlled studies have demonstrated preliminary support for treating PTSD with rTMS alone as well as with rTMS combined with psychotherapy. Similarly, there is some evidence that GAD can be treated with rTMS.

Coordinated regulation of hepatic FoxO1, PGC-1α and SREBP-1c facilitates insulin action and resistance.

Unlabelled: Type 2 diabetes is characterized by insulin resistance, hyperinsulinemia and hepatic overproduction of glucose and lipids. Insulin increases lipogenic enzyme expression by activating Akt and aPKC which activate SREBP-1c; this pathway is hyperactivated in insulin-resistant states. Insulin suppresses gluconeogenic enzyme expression by Akt-dependent phosphorylation/inactivation of FoxO1 and PGC-1α; this pathway is impaired in insulin-resistant states by aPKC excess, which displaces Akt from scaffolding-protein WD40/ProF, where Akt phosphorylates/inhibits FoxO1.

Biopsychosocial risk factors associated with chronic low back pain after lower limb amputation.

Low back pain is a common secondary health condition after lower limb amputation with important implications related to functional capabilities and overall quality of life. Despite the high prevalence of low back pain after lower limb amputation, the underlying etiologies of the disorder remain unknown. This hypothesis-driven communication provides evidence in support of using the multifactorial, biopsychosocial model of low back pain experience in the general population for identification of potential risk factors and rehabilitation targets for low back pain after lower limb amputation.
