Longitudinal associations between intersectional stigmas, antiretroviral therapy adherence, and viral load among women living with HIV using multidimensional latent transition item response analysis.

Background: In the US, Women, especially Black and Latina women living in disadvantaged environments, are disproportionally affected by HIV. Women living with HIV (WLHIV) have higher rates of suboptimal antiretroviral therapy (ART) adherence, and detectable viral load (VL). Experiences of intersectional poverty, HIV, gender, and racial stigmas may increase the rates of detectable VL through suboptimal ART adherence.

Efficacy, Safety, and Immunogenicity of the MATISSE (Maternal Immunization Study for Safety and Efficacy) Maternal Respiratory Syncytial Virus Prefusion F Protein Vaccine Trial.

Objective: To evaluate descriptive efficacy data, exploratory immunogenicity data, and safety follow-up through study completion from the global, phase 3 MATISSE (Maternal Immunization Study for Safety and Efficacy) maternal vaccination trial of bivalent respiratory syncytial virus (RSV) prefusion F protein vaccine (RSVpreF).

Methods: MATISSE was a phase 3, randomized, double-blinded, placebo-controlled trial. Healthy pregnant participants aged 49 years or younger at 24-36 weeks of gestation were randomized (1:1) to receive a single RSVpreF 120 micrograms or placebo dose.

Tirzepatide Associated With Reduced Albuminuria in Participants With Type 2 Diabetes: Pooled Post Hoc Analysis From the Randomized Active- and Placebo-Controlled SURPASS-1-5 Clinical Trials.

Objective: Tirzepatide, a long-acting, glucose-dependent insulinotropic polypeptide/glucagon-like peptide 1 receptor agonist, reduced urine albumin-to-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) decline in people with type 2 diabetes and high cardiovascular risk in the SURPASS-4 trial. To examine the generalizability of these findings, we assessed change from baseline in UACR for tirzepatide (5, 10, and 15 mg) compared with active and placebo treatment in a broad population from the SURPASS-1-5 trials.

Research Design And Methods: This post hoc analysis examined data from the overall pooled SURPASS-1-5 population and subgroups defined by baseline UACR ≥30 mg/g.

Integration of multi-omics and benchmark dose modeling to support adverse outcome pathways.

Background: Recent advancements in omics and benchmark dose (BMD) modeling have facilitated identifying the dose required for a predetermined change in a response (e.g. gene or protein change) that can be used to establish acceptable dose levels for hazardous exposures.

A generalised catalytic model to assess changes in risk for multiple reinfections with SARS-CoV-2.

Background: Monitoring trends in multiple infections with SARS-CoV-2, following several pandemic waves, provides insight into the biological characteristics of new variants, but also necessitates methods to understand the risk of multiple reinfections.

Objectives: We generalised a catalytic model designed to detect increases in the risk of SARS-CoV-2 reinfection, to assess the population-level risk of multiple reinfections.

Methods: The catalytic model assumes the risk of reinfection is proportional to observed infections and uses a Bayesian approach to fit model parameters to the number of nth infections among individuals that occur at least 90 days after a previous infection.

Misbehavior or misalignment? Examining the drift towards bureaucratic box-ticking in Competency-Based Medical Education.

Within competency-based medical education (CBME) residency programs, Entrustable Professional Activity (EPA) assessments endeavor to both bolster learning and inform promotion decisions. Recent implementation studies describe successes but also adverse effects, including residents and preceptors drifting towards bureaucratic / purely administrative behaviors and attitudes, although the drivers behind this tendency are not adequately understood. This study sought to examine resident and faculty experiences with implemented EPA processes to elucidate what leads them toward a 'tick-box' approach that has been described in the literature.

Global prioritization schemes vary in their impact on the placement of protected areas.

In response to global declines in biodiversity, many global conservation prioritization schemes were developed to guide effective protected area establishment. Protected area coverage has grown dramatically since the introduction of several high-profile biodiversity prioritization schemes, but the impact of such schemes on protected area establishment has not been evaluated. We used matching methods and a Before-After Control-Impact causal analysis to evaluate the impact of two key prioritization schemes-Biodiversity Hotspots and Last of the Wild-representing examples of the reactive and proactive ends of the prioritization spectrum.

Canadian forests are more conducive to high-severity fires in recent decades.

Canada has experienced more-intense and longer fire seasons with more-frequent uncontrollable wildfires over the past decades. However, the effect of these changes remains unknown. This study identifies driving forces of burn severity and estimates its spatiotemporal variations in Canadian forests.

TNF/TNFR Superfamily Members in Costimulation of T Cell Responses-Revisited.

Prosurvival tumor necrosis factor receptor (TNFR) superfamily (TNFRSF) members on T cells, including 4-1BB, CD27, GITR, and OX40, support T cell accumulation during clonal expansion, contributing to T cell memory. During viral infection, tumor necrosis factor superfamily (TNFSF) members on inflammatory monocyte-derived antigen-presenting cells (APCs) provide a postpriming signal (signal 4) for T cell accumulation, particularly in the tissues. Patients with loss-of-function mutations in TNFR/TNFSF members reveal a critical role for 4-1BB and CD27 in CD8 T cell control of Epstein-Barr virus and other childhood infections and of OX40 in CD4 T cell responses.

How Should Epidemiologists Respond to Data Genocide?

Data quality for and about American Indian/Alaska Native (AI/AN) people is undermined by deeply entrenched, colonial practices that have become standard in US federal data systems. This article draws on cases of maternal mortality and COVID-19 to demonstrate the ethical and clinical need for inclusive, diverse, and accurate data when researching AI/AN health trends. This article further argues that epidemiologists specifically must challenge implicit bias, question methods and practices, and recognize colonial, racist reporting practices about AI/AN people that have long undermined data collection, analytical, and dissemination practices that are fundamental to epidemiological research.

Escherichia coli phage-inducible chromosomal island aids helper phage replication and represses the LEE pathogenicity island.

In this study, we identify and characterize a novel phage-inducible chromosomal island found in commensal Escherichia coli MP1. This novel element, EcCIMP1, is induced and mobilized by the temperate helper phage vB_EcoP_Kapi1. EcCIMP1 contributes to superinfection immunity against its helper phage, impacting bacterial competition outcomes.

Background: A report by the American Association of Medical Colleges (AAMC) showed that academic anesthesiology has the highest prevalence of sexual harassment among specialties for both men and women. We aimed to explore the prevalence, sources, and impact of sexual harassment on anesthesiologists in academic centers in the United States and Canada. We also sought recommendations for its mitigation.

Three-dimensional movement and distribution of Tribolium castaneum (Coleoptera: Tenebrionidae) and Cryptolestes ferrugineus (Coleoptera: Laemophloeidae) in stored wheat at different temperatures and at different times.

Understanding the movement and distribution patterns of insects is crucial for developing effective stored grain management protocols. This research investigates 3-dimensional movement and distribution of Tribolium castaneum (Herbst) and Cryptolestes ferrugineus (Stephens) separately at different temperatures (5, 10, 20, and 30°C) and for different movement periods (1, 2, 3, and 24 h) in stored wheat with a uniform moisture content of 14.5% (wet basis).

The Effect of Window Size on Pathologists' Search for Rare Elements in a Digital Pathology Setting.

Context.—: Digital pathology requires pathologists to assess tissue digitally rather than on an analog microscope, which has been the mainstay tool for tissue assessment for more than a century. The impact of different digital interaction configurations on pathologists' performance is not well understood.

The nanoscale organization of the Nipah virus fusion protein informs new membrane fusion mechanisms.

Paramyxovirus membrane fusion requires an attachment protein for receptor binding and a fusion protein for membrane fusion triggering. Nipah virus (NiV) attachment protein (G) binds to ephrinB2 or -B3 receptors, and fusion protein (F) mediates membrane fusion. NiV-F is a class I fusion protein and is activated by endosomal cleavage.

Path integral Monte Carlo in a discrete variable representation with Gibbs sampling: Dipolar planar rotor chain.

In this work, we propose a path integral Monte Carlo approach based on discretized continuous degrees of freedom and rejection-free Gibbs sampling. The ground state properties of a chain of planar rotors with dipole-dipole interactions are used to illustrate the approach. Energetic and structural properties are computed and compared to exact diagonalization and numerical matrix multiplication for N ≤ 3 to assess the systematic Trotter factorization error convergence.

Transplant-Free Approach in Relapsed Hodgkin Lymphoma in Children, Adolescents, and Young Adults: A Nonrandomized Clinical Trial.

Importance: Retrieval strategies for children, adolescents, and young adults with relapsed classic Hodgkin lymphoma (cHL) aim to maintain efficacy while minimizing long-term toxic effects. Children, adolescents, and young adults with low-risk, relapsed cHL may benefit from replacing high-dose chemotherapy and autologous stem cell transplant with less intensive involved-site radiotherapy (ISRT).

Objective: To evaluate a risk-stratified, response-adapted, transplant-free approach for treatment of children, adolescents, and young adults with low-risk relapsed cHL with nivolumab plus brentuximab vedotin (BV) followed by BV plus bendamustine for patients with suboptimal response and ISRT (30.

Multicolor Cell Lineage Tracing Using MAGIC Markers Strategies.

Multicolor MAGIC Markers strategies are useful lineage tracing tools to study brain development at a multicellular scale. In this chapter, we describe an in utero electroporation method to simultaneously label multiple neighboring progenitors and their respective progeny using these multicolor reporters. In utero electroporation enables the introduction of any gene of interest into embryonic neural progenitors lining the brain ventricles through a simple pipeline consisting of a micro-injection followed by the application of electrical pulses.
