Interviewees described the intensive process of agency integration and identified primarily positive (e.g.

Racial/ethnic differences in neuropsychiatric disturbances associated with incident dementia.

Introduction: Neuropsychiatric symptoms (NPS) are nearly universal in dementia; some cross-sectional studies of NPS in dementia have found racial/ethnic differences, though it is unknown if NPS prevalence differs among racial/ethnic groups before and after dementia diagnosis.

Methods: Participants were followed annually at Alzheimer's Disease Centers and were assessed on the Neuropsychiatric Inventory-Questionnaire (NPI-Q) with at least one follow-up visit at which they were diagnosed with dementia. Descriptive statistics were generated by race/ethnicity.

Rates and Risk Factors for 30-Day Morbidity After One-Stage Vertical Banded Gastroplasty Conversions: A Retrospective Analysis.

The vertical banded gastroplasty (VBG) is a historic restrictive bariatric operation often requiring further surgery. In this investigation utilizing the 2021 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) national dataset, we aim to better define the outcomes of VBG conversions. We queried the 2021 MBSAQIP dataset for patients who underwent a conversion from a VBG to Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG).

Translational arrest and mRNA decay are independent activities of alphaherpesvirus virion host shutoff proteins.

The herpes simplex virus 1 (HSV1) virion host shutoff (vhs) protein is an endoribonuclease that regulates the translational environment of the infected cell, by inducing the degradation of host mRNA via cellular exonuclease activity. To further understand the relationship between translational shutoff and mRNA decay, we have used ectopic expression to compare HSV1 vhs (vhsH) to its homologues from four other alphaherpesviruses - varicella zoster virus (vhsV), bovine herpesvirus 1 (vhsB), equine herpesvirus 1 (vhsE) and Marek's disease virus (vhsM). Only vhsH, vhsB and vhsE induced degradation of a reporter luciferase mRNA, with poly(A)+   hybridization indicating a global depletion of cytoplasmic poly(A)+ RNA and a concomitant increase in nuclear poly(A)+ RNA and the polyA tail binding protein PABPC1 in cells expressing these variants.

Prediction of 30-Day Morbidity and Mortality After Conversion of Sleeve Gastrectomy to Roux-en-Y Gastric Bypass: Use of an Artificial Neural Network.

Background: Conversion of sleeve gastrectomy to Roux-en-Y gastric bypass is indicated primarily for unsatisfactory weight loss or gastroesophageal reflux disease (GERD). This study aimed to use a comprehensive database to define predictors of 30-day reoperation, readmission, reintervention, or mortality. An artificial neural network (ANN) was employed to optimize prediction of the composite endpoint (occurrence of 1+ morbid event).

A systematic search and narrative review of Aboriginal and Torres Strait Islander women and men pelvic health care: demonstrated need for improvement.

Unlabelled: Warning:This article contains terms, descriptions and opinions that may be culturally sensitive for Aboriginal and Torres Strait Islander peoples.

Background: Pelvic health conditions among Aboriginal and Torres Strait Islander women and men are under-recognised and under-reported despite indication of the significant burden of these conditions. Access to effective management provided in a culturally safe manner appears lacking.

Pathogenesis of Rift Valley Fever Virus in a BALB/c Mouse Model Is Affected by Virus Culture Conditions and Sex of the Animals.

Rift Valley fever virus (RVFV) is a mosquito-borne zoonotic pathogen causing disease in livestock and humans. Whilst initially restricted to the African continent, recent spread to the Arabian Peninsula has highlighted the likelihood of entry into new regions. Due to the absence of a regulatory-approved human vaccine, work is ongoing to develop and assess countermeasures.

Experiences of health care services among people with cognitive disabilities and mental health conditions.

Background: People with cognitive disabilities such as intellectual and developmental disabilities face significant barriers to accessing high-quality health care services. Barriers may be exacerbated for those with co-occurring mental health conditions.

Objective: This study compares patient experiences of health care services between adults with and without cognitive disabilities and, among people with a cognitive disability, those with and without co-occurring mental health conditions.

Effect of beta-blocker therapy on weight loss outcomes after sleeve gastrectomy & Roux-en-Y gastric bypass.

Background: Patients taking beta-blockers (BBs) commonly experience weight gain. There is limited research exploring how BBs impact weight loss after bariatric surgery.

Objectives: We examined how BBs impact 12-month weight loss in patients undergoing sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB).

The Effect of Fluid Pre-loading on Vital Signs and Hemodynamic Parameters in a Porcine Model of Lipopolysaccharide-Induced Endotoxemia.

Background Animal models of distributive hypotension and resuscitation allow the assessment of hemodynamic monitoring modalities and resuscitation strategies. The fluid-first paradigm for resuscitation is currently being challenged with clinical trials. In this investigation, venous return and perfusion are assessed, and full hemodynamics are characterized, in a porcine model of endotoxemic hypotension with and without fluid pre-loading.

Dysregulated metabolism of the late herpes simplex virus 1 transcriptome through the vhs-VP22 axis uncouples virus cytopathic effect and virus production.

Herpes simplex virus 1 (HSV1) expresses its genes in a classical cascade culminating in the production of large amounts of structural proteins to facilitate virus assembly. HSV1 lacking the virus protein VP22 (Δ22) exhibits late translational shutoff, a phenotype that has been attributed to the unrestrained activity of the virion host shutoff (vhs) protein, a virus-encoded endoribonuclease which induces mRNA degradation during infection. We have previously shown that vhs is also involved in regulating the nuclear-cytoplasmic compartmentalisation of the virus transcriptome, and in the absence of VP22 a number of virus transcripts are sequestered in the nucleus late in infection.

Outcomes of the "BRCA Quality Improvement Dissemination Program": An initiative to improve patient receipt of cancer genetics services at five health systems.

Objective: A quality improvement initiative (QII) was conducted with five community-based health systems' oncology care centers (sites A-E). The QII aimed to increase referrals, genetic counseling (GC), and germline genetic testing (GT) for patients with ovarian cancer (OC) and triple-negative breast cancer (TNBC).

Methods: QII activities occurred at sites over several years, all concluding by December 2020.

Central Venous Waveform Analysis and Cardiac Output in a Porcine Model of Endotoxemic Hypotension and Resuscitation.

Background: Cardiac output (CO) is a valuable proxy for perfusion, and governs volume responsiveness during resuscitation from distributive shock. The underappreciated venous system has nuanced physiology that confers valuable hemodynamic information. In this investigation, deconvolution of the central venous waveform by the fast Fourier transformation (FFT) algorithm is performed to assess its ability to constitute a CO surrogate in a porcine model of endotoxemia-induced distributive hypotension and resuscitation.

The top 10 research priorities in psoriatic arthritis: a James Lind Alliance Priority Setting Partnership.

Objectives: To identify and prioritize the top 10 research questions for PsA.

Methods: The British Psoriatic Arthritis Consortium (BritPACT) formed a Priority Setting Partnership (PSP) comprising of people living with PsA, carers and clinicians, supported by the James Lind Alliance (JLA). This PSP followed the established three-stage JLA process: first, an online survey of people living with PsA, carers and clinicians to identify PsA questions, asking, 'What do you think are the most important unanswered questions in psoriatic arthritis research?' The questions were checked against existing evidence to establish 'true uncertainties' and grouped as 'indicative questions' reflecting the overarching themes.

Implementation and outcome evaluations of a multi-site improvement program in cancer genetics.

Program evaluation can identify the successes and challenges of implementing clinical programs, which can inform future dissemination efforts. A cancer genetics improvement program, disseminated from the Lead Team's institution to five health systems (Participating Sites), was genetic counselor led, using virtual implementation facilitation to support Participating Sites' performance of quality improvement (QI) activities over several years. Program implementation and outcome evaluations were performed and included evaluation of program delivery and initial effects of the program on Participating Sites.

Methods: Data from the National Alzheimer's Coordinating Center are used to track switches between different states and types of antidepressant use.

Prediction of thirty-day morbidity and mortality after duodenal switch using an artificial neural network.

Background: Understanding factors that increase risk of both mortality and specific measures of morbidity after duodenal switch (DS) is important in deciding to offer this weight loss operation. Artificial neural networks (ANN) are computational deep learning approaches that model complex interactions among input factors to optimally predict an outcome. Here, a comprehensive national database is examined for patient factors associated with poor outcomes, while comparing the performance of multivariate logistic regression and ANN models in predicting these outcomes.

Herpes Simplex Virus 1 Expressing GFP-Tagged Virion Host Shutoff (vhs) Protein Uncouples the Activities of RNA Degradation and Differential Nuclear Retention of the Virus Transcriptome.

Virion host shutoff (vhs) protein is an endoribonuclease encoded by herpes simplex virus 1 (HSV1). vhs causes several changes to the infected cell environment that favor the translation of late (L) virus proteins: cellular mRNAs are degraded, immediate early (IE) and early (E) viral transcripts are sequestered in the nucleus with polyA binding protein (PABPC1), and dsRNA is degraded to help dampen the PKR-dependent stress response. To further our understanding of the cell biology of vhs, we constructed a virus expressing vhs tagged at its C terminus with GFP.
