Sinusitis and rhinitis among US veterans deployed to Southwest Asia and Afghanistan after September 11, 2001.

Background: Post-9/11 veterans were exposed to environmental and occupational pollutants during deployment.

Objective: Our aim was to determine associations between deployment-related exposures and sinusitis and rhinitis.

Methods: Between April 2018 and March 2020, veterans with land-based deployment after 9/11 who were living within 25 miles of 6 Department of Veteran Affairs medical centers were randomly chosen by using a Defense Manpower Data Center roster.

Improving quantitative neuromuscular monitoring: an education initiative on stimulating electrode placement.

Quantitative neuromuscular monitoring reduces the incidence of residual neuromuscular block, but broad acceptance of monitoring has been elusive despite recommendations for quantitative monitoring for decades. Acceptance of quantitative monitoring may, in part, be related to the quality of the data from monitoring systems. This evaluation explored proper stimulating electrode positioning for electromyographic (EMG) monitoring, the impact of an educational intervention on electrode positioning and anesthesia provider (anesthesiologist, resident, anesthetist) confidence in the monitoring data from the device.

Train-of-four ratio, counts and post tetanic counts with the Tetragraph electromyograph in comparison to mechanomyography.

Automated EMG devices to detect compound muscle action potentials from the adductor pollicis muscle in response to ulnar nerve stimulation, regardless of hand and thumb position, may serve as a better reference ("gold standard") for clinical assessment of neuromuscular function than traditional mechanomyography (MMG) systems that need custom design and validation in lab settings. This evaluation compared the TetraGraph EMG system against a validated MMG device to investigate the accuracy and repeatability of this quantitative EMG monitor for detecting onset, offset and deep neuromuscular block. Simultaneous muscle action potential recordings from the EMG neuromuscular monitor and muscle contractions from an in-house developed MMG monitor in response to ulnar nerve stimulation were obtained from patients having elective surgery requiring neuromuscular block.

Maternity care coordinator's experiences at the department of Veteran Affairs.

The Veterans Health Administration (VHA) provides maternity care by paying for Veterans to receive pregnancy-related care in community settings and by utilizing maternity care coordinators (MCCs) at each medical facility. The purpose of this qualitative descriptive study was to understand the MCC's experiences performing their role across VA facilities. Thirty MCCs were recruited and interviewed virtually using Microsoft Teams.

Implementation of a clinical pathway for the evaluation of asymptomatic hypertension in the emergency department.

Introduction: According to the guidelines of the American Heart Association and American College of Emergency Physicians, respectively, there is no indication for immediate lowering of asymptomatic hypertension in the Emergency Department (ED), and no requirement for routine diagnostic testing in these patients. Despite this, asymptomatic hypertension represents a recurring source of referrals for ED evaluation from other healthcare settings, or from patient self-referral, with significant practice variation in the evaluation and treatment of this complaint.

Methods: This is a pre-post study of a pathway to standardize care of patients presenting to a tertiary academic Veteran's Health Administration ED with asymptomatic hypertension.

Challenges and Opportunities in Developing an Oncology Clinical Trial Network in the United States Veterans Affairs Health Care System: The VA STARPORT Experience.

The United States Veterans Affairs (VA) Health Care System has a strong history of conducting impactful oncology randomized clinical trials (RCTs). We developed a phase II/III RCT to test the use of metastasis-directed therapy in Veterans with oligometastatic prostate cancer (OMPC)-the first VA RCT in OMPC that leverages novel imaging and advanced radiotherapy techniques. To accomplish this, we developed a clinical trial network to conduct the study.

How an Audit-and-Feedback-Based Educational Program Contributed to a Reduction in Environmentally Harmful Waste Anesthetic Gases Among Anesthesiology Residents.

Waste anesthetic gases (WAGs) contribute to greenhouse gas emissions. US anesthesiology resident education on how to reduce WAG-associated emissions is lacking, so we developed an electronic audit-and-feedback-based program to teach residents to reduce fresh gas flow (FGF) and WAG-associated emissions. To assess the program's effectiveness, we measured individual and combined mean FGF of residents during their first, second, and last weeks of the 4-week rotation; then, we calculated the extrapolated annual emissions based on the combined resident mean FGFs.

Vitamin E Attenuates Red-Light-Mediated Vasodilation: The Benefits of a Mild Oxidative Stress.

Red light (670 nm) energy controls vasodilation via the formation of a transferable endothelium-derived nitric oxide (NO)-precursor-containing substance, its intracellular traffic, and exocytosis. Here we investigated the underlying mechanistic effect of oxidative stress on light-mediated vasodilation by using pressure myography on dissected murine arteries and immunofluorescence on endothelial cells. Treatment with antioxidants Trolox and catalase decreased vessel dilation.

Three-Dimensional-Digital Image Correlation Methodology for Kinematic Measurements of Non-Penetrating Blunt Impacts.

Blunt force trauma remains a serious threat to many populations and is commonly seen in motor vehicle crashes, sports, and military environments. Effective design of helmets and protective armor should consider biomechanical tolerances of organs in which they intend to protect and require accurate measurements of deformation as a primary injury metric during impact. To overcome challenges found in velocity and displacement measurements during blunt impact using an integrated accelerometer and two-dimensional (2D) high-speed video, three-dimensional (3D) digital image correlation (DIC) measurements were taken and compared to the accepted techniques.

Exploring the Roles, Functions, and Work Experiences of Nurse Scientists in the Veterans Health Administration.

Objective: The aim of this project was to describe nurse scientists' roles, functions, and work experiences in the Veterans Health Administration (VHA).

Background: Nurse scientists play a critical role in shaping the culture of clinical inquiry and closing the gap between knowledge and practice.

Methods: A cross-sectional survey was used to collect information on sociodemographics, workload, research, clinical practice, education, and time/effort.

Clinical Impact of New Reference Intervals for the Roche Prolactin II Immunoassay.

Context: The Roche prolactin immunoassay is used throughout the world. It reports higher values than the Siemens immunoassay but the manufacturer-defined reference intervals are similar. Patient results are often above the Roche upper limit but within the Siemens interval, causing diagnostic confusion.

Phenocopy behavioral variant frontotemporal dementia: A case study.

Behavioral variant frontotemporal dementia (bvFTD) is a neurodegenerative condition characterized by progressive changes in behavior, cognition, and day-to-day functioning. Progression of the disease usually leads to death 3-5 years after diagnosis. However, there are reports of individuals who are initially diagnosed with bvFTD but fail to progress.

Red light mediates the exocytosis of vasodilatory vesicles from cultured endothelial cells: a cellular, and ex vivo murine model.

We have previously established that 670 nm energy induces relaxation of blood vessels via an endothelium derived S-nitrosothiol (RSNO) suggested to be embedded in vesicles. Here, we confirm that red light facilitates the exocytosis of this vasodilator from cultured endothelial cells and increases ex vivo blood vessel diameter. Ex vivo pressurized and pre-constricted facial arteries from C57Bl6/J mice relaxed 14.

Emergency department visits at Veterans Health Administration hospitals related to alcohol intoxication: A ten-year retrospective.

We sought to quantify and describe the volume of emergency department visits related to alcohol intoxication at the Veterans Health Administration (VHA), the largest healthcare system in the United States. This is a retrospective cohort study of patients with VHA emergency department visits for alcohol intoxication from 2010 to 2019 as identified via ICD-9/10 code and/or serum ethanol concentration >50 mg/dL. Encounters were identified and demographic and clinical data were acquired by automated query of the VHA Corporate Data Warehouse.

Methodological considerations for collecting and analyzing data on multiply marginalized psychology trainees with disabilities.

Objective/purpose: Historically, psychology trainees from marginalized communities have been underrepresented both as researchers and as participants in research on trainee experiences and outcomes. The current research can be used to develop evidence-based strategies to understand and improve the recruitment, retention, advancement, and overall training experiences of trainees with marginalized identities.

Method: We review the existing literature on the experiences of psychology trainees, particularly that focused on trainees from marginalized backgrounds.

The Essential Role of Senior Care Pharmacists in Antimicrobial Stewardship: An Updated Position Statement on Behalf of the American Society of Consultant Pharmacists and the Society of Infectious Diseases Pharmacists.

Senior care pharmacists are well-positioned to lead and drive antimicrobial stewardship (AMS) initiatives, not only through audit and data collection, but also through communication, collaboration, and cooperation with prescribers and nurses to influence prescribing behaviors. Senior care pharmacists are in a unique position to take a leadership role within the interprofessional team to achieve AMS goals. They should engage with the interprofessional team to promote the judicious and appropriate use of antimicrobials at their practice sites.

Profibrotic COVID-19 subphenotype exhibits enhanced localized ER-dependent HSP47 expression in cardiac myofibroblasts in situ.

We recently described a subgroup of autopsied COVID-19 subjects (∼40%), termed 'profibrotic phenotype,' who exhibited clusters of myofibroblasts (Mfbs), which were positive for the collagen-specific chaperone heat shock protein 47 (HSP47) in situ. This report identifies increased, localized (hot spot restricted) expression of αSMA, COLα1, POSTN and FAP supporting the identity of HSP47 cells as myofibroblasts and characterizing a profibrotic extracellular matrix (ECM) phenotype. Coupled with increased GRP78 in COVID-19 subjects, these data could reflect induction of the unfolded protein response for mitigation of proteostasis (i.
