Rationale & Objective: Dialysis patient care technicians (PCTs) provide essential, frontline care for patients receiving in-center hemodialysis. We qualitatively explored perceptions of the PCT job role, responsibilities, and training among current PCTs, non-PCT dialysis staff, and patients receiving hemodialysis.

Study Design: Focus group study.

Factors Associated With Mental Healthcare Utilization Among United States Military Personnel With Posttraumatic Stress Disorder or Depression Symptoms.

Introduction: Although posttraumatic stress disorder (PTSD) and depression are prominent mental health conditions affecting United States service members, only a subset of individuals with these conditions utilize mental healthcare services. Identifying factors associated with mental healthcare utilization may elucidate military subgroups with unmet mental healthcare needs.

Methods: Cross-sectional survey data from the 2019-2021 Millennium Cohort Study assessment were used to examine correlates of unmet mental healthcare needs among military personnel who screened positive for PTSD or depression symptoms (n=18,420) using modified Poisson regression models.

Characterizing PTSD symptom profiles in special forces operators and support personnel: Justification for a Precision Medicine Approach.

Given the large number and diverse types of PTSD symptoms, examination of subtypes within the comprehensive PTSD criteria is necessary. This is especially true for subpopulations of active-duty service members such as specialized military units that undergo assessment and selection, receive extensive training, and have significant operational experience and trauma exposure. The current study identified PTSD subtypes in 16,284 U.

Dementia Care Among United States Dialysis Providers: A Mixed Methods Study Evaluating Clinician Comfort and Knowledge.

Rationale & Objective: Given the high burden of dementia in dialysis patients, the dialysis workforce needs to be prepared to provide high-quality, person-centered dementia care. We explored comfort with and knowledge of dementia among US dialysis care providers.

Study Design: Web-based survey.

Conservation of mutation and recombination parameters between mammals and zebra finch.

Most of our understanding of the fundamental processes of mutation and recombination stems from a handful of disparate model organisms and pedigree studies of mammals, with little known about other vertebrates. To gain a broader comparative perspective, we focused on the zebra finch (), which, like other birds, differs from mammals in its karyotype (which includes many micro-chromosomes), in the mechanism by which recombination is directed to the genome, and in aspects of ontogenesis. We collected genome sequences from three generation pedigrees that provide information about 80 meioses, inferring 202 single-point mutations, 1,174 crossovers, and 275 non-crossovers.

Comparison of cognitive performance measures in individuals with systemic lupus erythematosus.

Objective: Cognitive impairment is a common complaint in SLE, but approaches to measuring cognitive performance objectively vary. Leveraging data collected in a population-based cohort of individuals with validated SLE, we compared performance and potential impairment across multiple measures of cognition.

Methods: During a single study visit (October 2019-May 2022), times to complete the Trail Making Test B (TMTB; N=423) were recorded; potential impairment was defined as an age-corrected and education-corrected T-score <35 (>1.

An examination of the potential core symptoms of posttraumatic stress disorder: What is integral after removing general psychopathology & distress?

Many confirmatory factor analyses (CFA) have examined the structure of posttraumatic stress disorder (PTSD) with some suggesting increased complexity (i.e., 6+ factors), while others suggesting a more refined structure (i.

Lateral Femoral Condyle Allograft in the Treatment of Elbow Capitellar Avascular Necrosis: A Case Report.

Case: A 27-year-old woman developed capitellar osteonecrosis after long-term corticosteroid use to treat non-Hodgkin lymphoma. She underwent an osteochondral reconstruction using a lateral femoral condyle (LFC) allograft. This graft was selected because it has a similar radius of curvature to the capitellum.

Fluid Cognition Among Individuals With Systemic Lupus Erythematosus.

Objective: We sought to describe fluid cognition and its correlates among individuals with systemic lupus erythematosus (SLE).

Methods: Participants (n = 199) were recruited from a population-based cohort for a single study visit (October 2019 to May 2022). Fluid cognition was measured via the National Institutes of Health Toolbox Fluid Cognition Battery (including episodic memory, working memory, attention and inhibitory control, processing speed, and cognitive flexibility domains) and expressed as age-corrected standard scores (mean 100, SD 15).

Impact of PTSD treatment on postconcussive symptoms in veterans: A comparison of sertraline, prolonged exposure, and their combination.

Many Veterans who served in Iraq and Afghanistan struggle with posttraumatic stress disorder (PTSD) and the effects of traumatic brain injuries (TBI). Some people with a history of TBI report a constellation of somatic, cognitive, and emotional complaints that are often referred to as postconcussive symptoms (PCS). Research suggests these symptoms may not be specific to TBI.

Patient Care Technician Staffing in US Hemodialysis Facilities: An Ecological Study.

Rationale & Objective: Technicians caring for patients receiving dialysis play a critical, frontline role in the care of patients receiving dialysis in the United States. We sought to provide a comprehensive description and identify correlates of US in-center hemodialysis facility patient care technician staffing patterns.

Study Design: This was an ecological study.

Patterns of recombination in snakes reveal a tug-of-war between PRDM9 and promoter-like features.

In some mammals, notably humans, recombination occurs almost exclusively where the protein PRDM9 binds, whereas in vertebrates lacking an intact , such as birds and canids, recombination rates are elevated near promoter-like features. To determine whether PRDM9 directs recombination in nonmammalian vertebrates, we focused on an exemplar species with a single, intact ortholog, the corn snake (). Analyzing historical recombination rates along the genome and crossovers in pedigrees, we found evidence that PRDM9 specifies the location of recombination events, but we also detected a separable effect of promoter-like features.

Psychological Factors That Affect Return to Sport After Surgical Intervention for Shoulder Instability: A Systematic Review.

Background: Recent advances have begun to identify the nonphysical factors facilitating successful return to sport (RTS) after shoulder instability surgery, yet little is currently known regarding psychological factors and RTS.

Purpose/hypothesis: The purposes of this study were to (1) identify psychological factors associated with RTS, (2) evaluate the prognostic utility of various psychological factors, and (3) evaluate the available metrics used to assess psychological RTS readiness. It was hypothesized that psychological factors would be identified as critical elements influencing a patient's RTS.

Physical Performance in a Diverse, Population-Based Cohort of Individuals With Systemic Lupus Erythematosus.

Objective: To report the burden and correlates of poor physical performance in a diverse cohort of individuals with systemic lupus erythematosus (SLE).

Methods: In this single-visit study of 446 individuals with SLE from a population-based metropolitan Atlanta cohort, we measured physical performance via the Short Physical Performance Battery (score range 0-12; intermediate-low [<10] vs high [≥10]). We also collected demographic, clinical, and psychosocial variables and examined the associations (adjusted odds ratios [aORs]) of intermediate-low versus high physical performance with these characteristics via multivariable logistic regression.

Prospective multicentre study of indications for surgery in patients with idiopathic acute pancreatitis following endoscopic ultrasonography (PICUS).

Background: Cholecystectomy in patients with idiopathic acute pancreatitis (IAP) is controversial. A randomized trial found cholecystectomy to reduce the recurrence rate of IAP but did not include preoperative endoscopic ultrasonography (EUS). As EUS is effective in detecting gallstone disease, cholecystectomy may be indicated only in patients with gallstone disease.

Psychedelic-Assisted Therapy in Military and Veterans Healthcare Systems: Clinical, Legal, and Implementation Considerations.

Purpose Of Review: This review discusses the current and projected landscape of psychedelic-assisted therapy (PAT), with a focus on clinical, legal, and implementation considerations in Department of Defense (DoD) and Department of Veterans Affairs (VA) healthcare systems.

Recent Findings: 3,4-Methylenedioxymethamphetamine (MDMA)- and psilocybin-assisted therapy have shown promising outcomes in efficacy, safety, tolerability, and durability for PTSD and depression, respectively. MDMA-assisted therapy is already approved by the Food and Drug Administration (FDA) on an Expanded Access ("compassionate use") basis for PTSD, with full approval projected for 2024.

Remote Administration of Physical and Cognitive Performance Assessments in a Predominantly Black Cohort of Persons With Systemic Lupus Erythematosus.

Objective: In a study of physical and cognitive functioning among predominantly Black individuals with systemic lupus erythematosus (SLE), we compared remotely administered physical and cognitive performance assessments to those collected in person.

Methods: A subset of participants who completed an in-person visit in our parent study from 2021 to 2022 (n = 30) were recruited to complete a second, remote visit within 28 days. Physical performance (measured by a modified Short Physical Performance Battery [SPPB]; range 0-12; subscale ranges 0-4; higher = better performance) and cognitive performance (episodic and working memory adjusted t-scores, measured using NIH Toolbox) were measured at both visits.

Diagnostic accuracy of endoscopic ultrasonography-guided tissue acquisition prior to resection of pancreatic carcinoma: a nationwide analysis.

Introduction: Endoscopic ultrasonography guided tissue acquisition (EUS + TA) is used to provide a tissue diagnosis in patients with suspected pancreatic cancer. Key performance indicators (KPI) for these procedures are rate of adequate sample (RAS) and sensitivity for malignancy (SFM).

Aim: assess practice variation regarding KPI of EUS + TA prior to resection of pancreatic carcinoma in the Netherlands.

Patterns of recombination in snakes reveal a tug of war between PRDM9 and promoter-like features.

In vertebrates, there are two known mechanisms by which meiotic recombination is directed to the genome: in humans, mice, and other mammals, recombination occurs almost exclusively where the protein PRDM9 binds, while in species lacking an intact , such as birds and canids, recombination rates are elevated near promoter-like features. To test if PRDM9 also directs recombination in non-mammalian vertebrates, we focused on an exemplar species, the corn snake (). Unlike birds, this species possesses a single, intact ortholog.

Associations of health care staff burnout with negative health and organizational outcomes in the U.S. military health system.

Rationale: Burnout is a personal and occupational phenomenon that has been associated with negative physical and psychological outcomes in medical staff. Additionally, there are implications for healthcare organizations, as those staff who are burned out are more likely to have lower productivity or leave the organization. As with the Covid-19 pandemic, future national emergencies and potentially large-scale conflicts will require similar and likely even larger scale responses from the U.

Calibrating the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) for detecting alcohol-related problems among Canadian, UK and US soldiers: cross-sectional pre-deployment and post-deployment survey results.

Objectives: Excessive alcohol use can bring about adverse health and work-related consequences in civilian and military populations. Screening for excessive drinking can help identify individuals at risk for alcohol-related problems who may require clinical interventions. The brief validated measures of alcohol use such as the Alcohol Use Disorders Identification Test (AUDIT), or abbreviated AUDIT-Consumption (AUDIT-C), are often included in military deployment screening and epidemiologic surveys, but appropriate cut-points must be used to effectively identify individuals at risk.
