The Autonomic Nervous System (ANS)-Immune Network in People Living With HIV.

Purpose: Pre-clinical studies have demonstrated direct influences of the autonomic nervous system (ANS) on the immune system. However, it remains unknown if connections between the peripheral ANS and immune system exist in humans and contribute to the development of chronic inflammatory disease. This study had three aims: 1.

Your Move: A Cluster Randomized Controlled Trial of a Blended Learning Sexual Health Program.

Purpose: To evaluate the efficacy of Your Move, a multisession blended learning sexual health education program for females aged 14-19 years.

Methods: This group randomized controlled trial included a sample of 104 groups comprised of 808 females aged 14-19 years. After completing the baseline survey, small groups of 4-16 participants were randomized, stratified by 6 regions, to receive Your Move (n = 58 groups, 412 participants) or an attention control program called Eat Smart (n = 46 groups, 396 participants).

Nutritional profiling of plant-based meat alternatives and ground beef.

The objective of this study was to characterize the nutritional profile of plant-based meat alternatives (PBMA) and ground beef (GB). Beyond Beef (BEY); Impossible Burger (IMP), a third available product of plant-based protein, including SWEET EARTH, Incogmeato, Open Nature, and Good & Gather (GEN); and two lean levels of GB (regular [80%-85% lean, regular ground beef] and Lean [>93% lean, lean ground beef, LGB]) were purchased from retail stores across the United States. Proximate composition, mineral content, fatty acid profile, amino acid profile, and B-vitamin content were measured in raw products.

Healthcare utilization and costs following molecular diagnostic testing among patients with vaginitis.

Vaginitis and other vaginal discharge syndromes lead to high healthcare utilization. Molecular tests like syndromic multiplex real-time (RT) polymerase chain reaction (PCR)-based tests are highly sensitive and specific at diagnosing the infectious causes of vaginitis. This study compared the healthcare resource utilization (HCRU) and direct all-cause healthcare costs among patients with vaginitis in the US receiving next-day syndromic multiplex RT-PCR tests with those receiving other PCR tests or no diagnostic test of interest.

Autonomic and Immune Stress Response Networks in Patients Living With HIV.

Background And Objectives: Stress response systems are frequently dysregulated in patients with chronic inflammatory disorders. Pre-clinical studies have demonstrated direct influences of the sympathetic and vagal/parasympathetic branches of the autonomic nervous system (ANS) on the immune system. However, these connections have not been examined in humans.

Gastrointestinal Dysmotility, Autonomic Function and Small Intestinal Bacterial Overgrowth Among People with Well-Controlled HIV.

Introduction: Gastrointestinal dysfunction, including microbiome changes and increased translocation across a compromised gastrointestinal barrier plays a role in the chronic inflammation experienced by people with HIV (PWH). It is unknown whether autonomic neuropathy (AN) may contribute to these mechanisms by altering gastrointestinal motility.

Methods: This is a cross-sectional study of 100 PWH and 89 controls.

Ribosome Quality Control mitigates the cytotoxicity of ribosome collisions induced by 5-Fluorouracil.

Ribosome quality control (RQC) resolves collided ribosomes, thus preventing their cytotoxic effects. The chemotherapeutic agent 5-Fluorouracil (5FU) is best known for its misincorporation into DNA and inhibition of thymidylate synthase. However, while a major determinant of 5FU's anticancer activity is its misincorporation into RNAs, the mechanisms by which cancer cells overcome the RNA-dependent 5FU toxicity remain ill-defined.

A Modular Biosensor Design for Quantitative Measurement of Free Nedd8.

The objective of our study was to develop a genetically encoded biosensor for quantification of Nedd8, a post-translational modifier that regulates cellular signals through conjugation to other proteins. Perturbations in the balance of free (i.e.

ALDH1A3 is the switch that determines the balance of ALDH and CD24CD44 cancer stem cells, EMT-MET, and glucose metabolism in breast cancer.

Plasticity is an inherent feature of cancer stem cells (CSCs) and regulates the balance of key processes required at different stages of breast cancer progression, including epithelial-to-mesenchymal transition (EMT) versus mesenchymal-to-epithelial transition (MET), and glycolysis versus oxidative phosphorylation. Understanding the key factors that regulate the switch between these processes could lead to novel therapeutic strategies that limit tumor progression. We found that aldehyde dehydrogenase 1A3 (ALDH1A3) regulates these cancer-promoting processes and the abundance of the two distinct breast CSC populations defined by high ALDH activity and CD24CD44 cell surface expression.

Promoting Healthy Adolescent Romantic Relationships: Results of a Multisite, Two-group Parallel Randomized Clinical Trial.

Purpose: To examine the impact of About Us, an innovative healthy relationships intervention that promotes positive adolescent romantic relationships and the use of effective contraceptives, on improving behavior, attitudes, and intentions related to sexual intercourse, relationship communication, and conflict resolution at 3- and 9-month follow-up, compared to services as usual.

Methods: This was a multi-site, two-group, parallel, randomized-controlled trial with an intervention/comparison allocation ratio of 3:2 conducted at seven high schools in California between February 2018 and May 2021.

Results: Overall, our study did not find statistically significant evidence of improved behavior, attitudes, and intentions related to sexual intercourse, relationship communication, and conflict resolution among participants (14-18 years old) randomized to the intervention group (n = 316) compared to services as usual (n = 217) during follow-up (group x time; p > .

The Lifetime Health and Economic Burden of Smokeless Tobacco use in Bangladesh, India, and Pakistan: Results From ASTRAMOD.

Introduction: Under the current policy landscapes, the lifetime health and economic burden of smokeless tobacco (ST) products, consumed by over 297 million ST users in South Asia, is unknown. The aim of this study was to estimate the lifetime health effects and costs attributable to current and future ST use in Bangladesh, India, and Pakistan where the majority of ST users live.

Aims And Methods: We developed a Markov-based state-transition model (ASTRAMOD) to predict the lifetime costs of treatment of four diseases (oral, pharyngeal, esophageal cancers, and stroke) and disability-adjusted life years (DALYs), attributable to the current and future use of ST under existing ST policy scenario.

Real-World Effectiveness of Once-Weekly Glucagon-Like Peptide-1 Receptor Agonists (OW GLP-1RAs) in Comparison with Dipeptidyl Peptidase-4 Inhibitors (DPP-4is) for Glycemic Control and Weight Outcomes in Type 2 Diabetes Mellitus (RELATE).

Background: The efficacy of once-weekly (OW) glucagon-like peptide-1 receptor agonists (GLP-1RAs) has been established in several trials in people with type 2 diabetes mellitus (T2DM); however, real-world evidence on their effectiveness is limited. This study evaluated the effectiveness of OW GLP-1RA regarding glycemic and weight outcomes, and relative to DPP-4i in a comparator analysis.

Methods: This observational cohort study evaluated glycated hemoglobin (HbA) and weight outcomes in people with T2DM with two or more prescription claims for the same OW GLP-1RA using a pre-post study design (including for a semaglutide OW T2DM subgroup, hereafter referred to as semaglutide).

Exploring the Influence of Romantic Relationship Communication on Adolescents' Self-Efficacy to Ask for Sexual Consent.

Adolescence represents a crucial period for sexual and romantic relationship development, and acquisition of skills and confidence essential for effective sexual consent communication. However, various barriers may interfere with adolescents' belief in their ability (i.e.

Influence of provider openness and leadership behaviors on adherence to motivational interviewing training implementation strategies: Considerations for evidence-based practice delivery.

Background: Adherence to intervention training implementation strategies is at the foundation of fidelity; however, few studies have linked training adherence to trainee attitudes and leadership behaviors to identify what practically matters for the adoption and dissemination of evidence-based practices. Through the conduct of this hybrid type 3 effectiveness-implementation cluster randomized controlled trial, we collected Exploration, Preparation, Implementation, and Sustainment (EPIS) data and merged it with tailored motivational interviewing training adherence data, to elucidate the relationship between provider attitudes toward evidence-based practices, leadership behaviors, and training implementation strategy (e.g.

Building an HIV Learning Health Care Community for Youth in Florida: Opportunities and Challenges.

In Florida, 33% of new HIV infections among men and 21% of new infections among women are among those younger than 29 years of age. We describe the development of a Learning Health Care Community for youth (Y-LHCC) in Orange County, FL. Its core implementation team (iTeam) was composed of representatives from community agencies and academics, whose work was informed by data from the Florida Department of Health (FDOH) and regional research, in-depth interviews (IDIs) with agency representatives, and a pilot implementation of Tailored Motivational Interviewing (TMI) to improve service provision.

Effectiveness, Acceptability, and Feasibility of a Telehealth HIV Pre-Exposure Prophylaxis Care Intervention Among Young Cisgender Men and Transgender Women Who Have Sex With Men: Protocol for a Randomized Controlled Trial.

Background: Despite its promise for HIV prevention, the uptake of pre-exposure prophylaxis (PrEP) has been slow, and there have been substantial inequities in PrEP access. Young men who have sex with men and transgender women of color are most in need of PrEP and least likely to have that need fulfilled. PrEP telehealth care, which provides remote PrEP care via electronic communication, seems well suited to address several of the challenges of PrEP provision, including discomfort with stigmatizing and difficult-to-access health care systems, transportation challenges, and privacy concerns, and address disparities in PrEP access.

Investigating Real-World Benztropine Usage Patterns in Movement Disorders: Claims Analysis and Health Care Provider Survey Results.

To evaluate real-world treatment patterns for patients initiating benztropine and to understand treatment approaches in patients with drug-induced movement disorders from a health care provider perspective. A retrospective claims analysis was conducted among patients with evidence of benztropine initiation from January 2017 through March 2020 to assess treatment patterns and patient health care resource utilization. Subsequently, a 30-minute, United States-based online survey fielded from December 2021 to January 2022 was sent to physicians, nurse practitioners, and physician assistants who reported a primary care or psychiatry specialty currently treating drug-induced movement disorders and prescribed benztropine.

Exploiting the fibroblast growth factor receptor-1 vulnerability to therapeutically restrict the MYC-EZH2-CDKN1C axis-driven proliferation in Mantle cell lymphoma.

Mantle cell lymphoma (MCL) is a lethal hematological malignancy with a median survival of 4 years. Its lethality is mainly attributed to a limited understanding of clinical tumor progression and resistance to current therapeutic regimes. Intrinsic, prolonged drug treatment and tumor-microenvironment (TME) facilitated factors impart pro-tumorigenic and drug-insensitivity properties to MCL cells.

Sex related differences in muscle health and metabolism in chronic obstructive pulmonary disease.

Background & Aims: Sex differences in muscle function and mass, dyspnea, and clinical outcomes have been observed in patients with Chronic Obstructive Pulmonary Disease (COPD) despite a similar level of airflow obstruction. Protein and amino acid metabolism is altered in COPD, however, it remains unclear whether a difference in metabolic signature exists between males and females with COPD that may explain the observed differences in muscle health and clinical outcomes.

Methods: In 234 moderate to severe COPD patients (males/females: 113/121) and 182 healthy controls (males/females: 77/105), we assessed, besides presence of comorbidities and clinical features, muscle function by handgrip and leg dynamometry, and body composition by dual-energy x-ray absorptiometry.

A novel cell-based screen identifies chemical entities that reverse the immune-escape phenotype of metastatic tumours.

Genetic and epigenetic events have been implicated in the downregulation of the cellular antigen processing and presentation machinery (APM), which in turn, has been associated with cancer evasion of the immune system. When these essential components are lacking, cancers develop the ability to subvert host immune surveillance allowing cancer cells to become invisible to the immune system and, in turn, promote cancer metastasis. Here we describe and validate the first high-throughput cell-based screening assay to identify chemical extracts and unique chemical entities that reverse the downregulation of APM components in cell lines derived from metastatic tumours.

Understanding implementation completion of tailored motivational interviewing in multidisciplinary adolescent HIV clinics.

Background: Understanding the barriers and facilitators of implementation completion is critical to determining why some implementation efforts fail and some succeed. Such studies provide the foundation for developing further strategies to support implementation completion when scaling up evidence-based practices (EBPs) such as Motivational Interviewing.

Method: This mixed-methods study utilized the Exploration, Preparation, Implementation, and Sustainment framework in an iterative analytic design to compare adolescent HIV clinics that demonstrated either high or low implementation completion in the context of a hybrid Type III trial of tailored motivational interviewing.

Addressing Natural Killer Cell Dysfunction and Plasticity in Cell-Based Cancer Therapeutics.

Natural killer (NK) cells are cytotoxic group 1 innate lymphoid cells (ILC), known for their role as killers of stressed, cancerous, and virally infected cells. Beyond this cytotoxic function, NK cell subsets can influence broader immune responses through cytokine production and have been linked to central roles in non-immune processes, such as the regulation of vascular remodeling in pregnancy and cancer. Attempts to exploit the anti-tumor functions of NK cells have driven the development of various NK cell-based therapies, which have shown promise in both pre-clinical disease models and early clinical trials.

High School FLASH Sexual Health Education Curriculum: LGBTQ Inclusivity Strategies Reduce Homophobia and Transphobia.

Homophobic and transphobic beliefs that lead to bias-based harassment remain a critical concern for young people in the USA. The aim of the present study was to examine the impact of an inclusive comprehensive sex education program (High School FLASH) on homophobic and transphobic beliefs. Data from this study come from a randomized controlled trial that evaluated the impact of High School FLASH on students' sexual behaviors and related outcomes with 20 schools in two U.
