Associations between the gut microbiome, inflammation and cardiovascular profiles in people with HIV.

Background: Inflammation and innate immune activation are associated with chronic HIV infection, despite effective treatment. Although gut microbiota alterations are linked to systemic inflammation, the relationships between the gut microbiome, inflammation and HIV remain unclear.

Methods: The UPBEAT-CAD sub-study, examining cardiovascular disease (CVD) risk in HIV, enrolled participants matched on HIV status and traditional CVD risk factors.

Promoting Evidence-Based Tobacco Cessation Treatment in Community Mental Health Clinics: Results of a Pilot Implementation Study: Promouvoir le traitement de sevrage tabagique fondé sur des données probantes dans les cliniques communautaires de santé mentale : résultats d'une étude pilote de mise en œuvre.

Objective: Tobacco smoking is the leading cause of preventable death among individuals with serious mental illness (SMI) but few persons with SMI are offered smoking cessation treatment. The purpose of this study was to pilot-test a multicomponent intervention to increase the delivery of evidence-based smoking cessation treatment in community mental health clinics (CMHCs).

Method: This study was carried out at five CMHCs in Maryland involving clinicians who participated in training in smoking cessation.

Inherent instability of simple DNA repeats shapes an evolutionarily stable distribution of repeat lengths.

Using the Telomere-to-Telomere reference, we assembled the distribution of simple repeat lengths present in the human genome. Analyzing over two hundred mammalian genomes, we found remarkable consistency in the shape of the distribution across evolutionary epochs. All observed genomes harbor an excess of long repeats, which are prone to developing into repeat expansion disorders.

#natural, #vegan, #healing: A Content Analysis of Health Content Among Instagram Posts Focused on Cannabis Edibles.

Background: Despite limited scientific evidence, public perceptions of cannabis as health enhancing are significant. As food products, cannabis edibles (edibles), may also leverage food-related associations that convey health. Social media is a prominent and influential source of largely unregulated cannabis information and a potential place to correct misinformation.

Investigating the frequency of neural autoantibodies in refractory focal epilepsy.

Objectives: There have been conflicting reports about the frequency of neural autoantibodies in epilepsy cohorts, which is confounded by the lack of clear distinction of epilepsy from acute symptomatic seizures due to encephalitis. The aim of this study was to determine the frequency of neural autoantibodies in a well characterised population of refractory focal epilepsy of known and unknown cause.

Methods: Cases were recruited from epilepsy outpatient clinics at the Princess Alexandra, Mater, Royal Brisbane and Women's and Cairns Base Hospitals from 2021 - 2023.

Short Term Estradiol Administration Does Not Restore Endothelin-B Receptor-Mediated Vasodilation in Postmenopausal Women.

The endothelin-B receptor (ETR) mediates vasodilation in young women, an effect that is absent in postmenopausal women. We have previously demonstrated that ETR-mediated vasodilation is regulated by estradiol (E) in young women; however, the impact of E on ETR function in postmenopausal women remains unknown. Accordingly, the objective of this study was to test the hypothesis that E exposure restores ETR-mediated dilation in postmenopausal women.

Plaque heterogeneity influences in-stent restenosis following drug-eluting stent implantation: Insights from patient-specific multiscale modelling.

In-stent restenosis represents a major cause of failure of percutaneous coronary intervention with drug-eluting stent implantation. Computational multiscale models have recently emerged as powerful tools for investigating the mechanobiological mechanisms underlying vascular adaptation processes during in-stent restenosis. However, to date, the interplay between intervention-induced inflammation, drug delivery and drug retention has been under-investigated.

Is the Affordable Care Act Medicaid expansion in the USA associated with reductions in intimate partner violence victimisation?

Objective: Intimate partner violence (IPV) affects an estimated 47% of women living in the USA in their lifetime and is associated with increased risk of physical and mental health concerns. Current prevention efforts focus on individual and family-level interventions rather than macrosystem-level policies. Thus, we sought to test the effects of Medicaid expansion on the rates of IPV and violence more broadly.

Climate Therapy: Sustainability Solutions for Breast Cancer Care in the Anthropocene Era.

Climate change is the greatest threat to human existence. Currently it impacts breast cancer care by disrupting treatment, by food poverty and economic hardship and through fossil fuel pollution which increases breast cancer incidence. These impacts are greatest in those already experiencing deprivation.

Protocol: A mixed-methods study to evaluate implementation and outcomes of U.S. state telemental health policy expansion during the COVID-19 pandemic.

Background: Until the COVID-19 pandemic, it had not been possible to examine the effect of rapid policy changes surrounding telemental health on patient-reported mental health care access, costs, symptoms, and functioning. Sizable variation in telemental health use by patient race-ethnicity, age, and rurality, and in its adoption across healthcare settings, underscores the need to study equitable dissemination and implementation of high-quality telemental health services in the real world. This protocol describes an explanatory sequential mixed-methods study that aims to examine the effects of state telemental health policy expansion on patient-reported mental health outcomes, as well as the policy-to-practice pathway from the perspectives of state leaders, clinicians, and staff who care for underserved patients.

The social determinants of resilience: A conceptual framework to integrate psychological and policy research.

The psychological study of resilience has increasingly underscored the need for children and families to access material and psychological resources to positively adapt to significant stress. Redistributive policies-policies that downwardly reallocate society's social and economic resources-can offer economically disadvantaged families sustained access to these resources and mitigate the harmful impacts of adversity. This conceptual article builds upon and integrates insights from psychological and policy research to develop a unifying multilevel resilience framework, which we call the Social Determinants of Resilience.

The Translational Science Benefits Model, a new training tool for demonstrating implementation science impact: A pilot study.

Introduction: Demonstrating the impact of implementation science presents a new frontier for the field, and operationalizing downstream impact is challenging. The Translational Science Benefits Model (TSBM) offers a new approach for assessing and demonstrating research impact. Here we describe integration of the TSBM into a mentored training network.

Understanding the factors that impact federal rulemaking: a survey of former EPA regulators.

While federal rulemaking is an essential part of American governance, it is not well understood by researchers and advocates. We surveyed 115 former regulators at the Environmental Protection Agency to understand their views on the kinds of information they valued most and their communication preferences (June-August 2023). Respondents highly valued information about the scope of a problem (96%), legal analysis (97%), technology assessments (96%), and impacts of a proposed rule (99%).

Potent and Selective SETDB1 Covalent Negative Allosteric Modulator Reduces Methyltransferase Activity in Cells.

A promising drug target, SETDB1, is a dual Kme reader and methyltransferase, which has been implicated in cancer and neurodegenerative disease progression. To help understand the role of the triple Tudor domain (3TD) of SETDB1, its Kme reader, we first identified a low micromolar small molecule ligand, UNC6535, which occupies simultaneously both the TD2 and TD3 reader binding sites. Further optimization led to the discovery of UNC10013, the first covalent 3TD ligand targeting Cys385 of SETDB1.

Target Trial Emulation for Evaluating Health Policy.

Target trial emulation is an approach to designing rigorous nonexperimental studies by "emulating" key features of a clinical trial. Most commonly used outside of policy contexts, this approach is also valuable for policy evaluation as policies typically are not randomly assigned. In this article, we discuss the application of the target trial emulation framework in a policy evaluation context.

Characterizing vascular and hormonal changes in women across the life span: a cross-sectional analysis.

Vascular dysfunction, marked by lower endothelial function and increased aortic stiffness, is a nontraditional risk factor that precedes the development of cardiovascular disease (CVD). However, the age at which these changes in vascular function occur in women and the degree to which reproductive hormones mediate these changes has not been characterized. Women free from major disease were enrolled across the adult life span (aged 18-70 yr, = 140).

Benign pericholecystic regeneration mimicking hepatocellular carcinoma: a potential pitfall in imaging of cirrhosis.

Several pseudolesions mimicking malignancy have been reported in cirrhotic and non-cirrhotic livers. Pericholecystic regeneration is among those pseudolesions and can occasionally mimic malignancy. Herein we present a case series comprised of 10 cirrhotic patients (majority due to alcoholic liver disease [ALD] or metabolic dysfunction associated steatotic liver disease [MASLD]) with pericholecystic observations initially categorized as highly suspicious for HCC (LR-4 and LR-5) due to their suspicious enhancement pattern which were later proven to be benign based on biopsy, transplantation or imaging criteria (stability of size and morphology on serial CT or MRI for > 2 years).

Asundexian versus Apixaban in Patients with Atrial Fibrillation.

Background: Stroke prevention with direct-acting oral anticoagulant agents in patients with atrial fibrillation confers a risk of bleeding and limits their use. Asundexian, an activated factor XI (XIa) inhibitor, is an oral anticoagulant that may prevent strokes with less bleeding.

Methods: In a phase 3, international, double-blind trial, we randomly assigned high-risk patients with atrial fibrillation in a 1:1 ratio to receive asundexian at a dose of 50 mg once daily or standard-dose apixaban.
