ACSL4-mediated H3K9 and H3K27 hyperacetylation upregulates SNAIL to drive TNBC metastasis.

Triple-negative breast cancer (TNBC) has profound unmet medical need globally for its devastating clinical outcome associated with rapid metastasis and lack of targeted therapies. Recently, lipid metabolic reprogramming especially fatty acid oxidation (FAO) has emerged as a major driver of breast cancer metastasis. Analyzing the expression of major FAO regulatory genes in breast cancer, we found selective overexpression of acyl-CoA synthetase 4 (ACSL4) in TNBC, which is primarily attributed to the absence of progesterone receptor.

Stigma and discrimination faced by adolescents living with HIV and experiencing depression in Malawi.

Background: In Malawi, approximately 25% of adolescents living with HIV (ALWH) also suffer from depression. Not only is HIV stigma a major contributor to depression but it also adversely impacts HIV care engagement. ALWH can experience HIV stigma as stereotyping, social exclusion, low social support, and abuse, and these experiences are associated with poor mental health.

Developmental Trajectories of Transactional Sex and Age-Disparate Relationships During Adolescence: An HPTN 068 Analysis.

Transactional sex and sexual relationships with older partners increase HIV risk in adolescent girls and young women (AGYW), yet little is known about how these behaviors co-evolve over time. We characterize temporal patterns of transactional sex and age-disparate relationships among AGYW in South Africa. Longitudinal data are from a randomized controlled trial (HPTN 068) of school-aged, HIV-negative, AGYW who attended ≥ 3 study visits.

Elevated stress-responsive biomarkers are associated with HIV acquisition in young women in rural South Africa.

Objective: Biological markers of stress have been associated with HIV progression and pathogenesis but not with HIV incidence. We sought to determine if elevated stress-responsive biomarkers would be associated with incident HIV among adolescent girls and young women (AGYW).

Design: We conducted a case-cohort study within the HIV Prevention Trials Network (HPTN) 068 study among 949 AGYW in South Africa.

Remote-Use Applications of the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised Clinical Outcome Assessment Tool: A Scoping Review.

Objectives: In 2021, the US Congress passed the Accelerating Access to Critical Therapies for Amyotrophic Lateral Sclerosis Act. The law encourages development of "tools, methods, and processes" to improve clinical trial efficiency for neurodegenerative diseases. The Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) is an outcome measure administered during in-person clinic visits and used to support investigational studies for persons living with amyotrophic lateral sclerosis.

Friendship Bench Intervention to Address Depression and Improve HIV Care Engagement Among Adolescents Living with HIV in Malawi: Study Protocol for a Pilot Randomized Controlled Trial.

Background: Adolescents in Sub-Saharan Africa are disproportionately affected by the HIV epidemic. Comorbid depression is prevalent among adolescents living with HIV (ALWH) and poses numerous challenges to HIV care engagement and retainment. We present a pilot trial designed to investigate feasibility, fidelity, and acceptability of an adapted and an enhanced Friendship Bench intervention (henceforth: AFB and EFB) in reducing depression and improving engagement in HIV care among ALWH in Malawi.

Trajectories of intimate partner violence and their relationship to stress among young women in South Africa: An HPTN 068 study.

Background: One in four South African women will experience intimate partner violence (IPV) in their lifetime, potentially increasing their biological stress. In South Africa, limited IPV and stress research has utilized multiple timepoints or examined modifying factors. Cash transfers (CTs) are associated with reduced IPV and stress and may be an intervention target.

Characterizing Network-Based HIV Testing Interventions to Guide HIV Testing and Contact Tracing at STI Clinics in Lilongwe, Malawi.

Background: Understanding heterogeneity across patients in effectiveness of network-based HIV testing interventions may optimize testing and contact tracing strategies, expediting linkage to therapy or prevention for contacts of persons with HIV (PWH).

Setting: We analyzed data from a randomized controlled trial of a combination intervention comprising acute HIV testing, contract partner notification (cPN), and social contact referral conducted among PWH at 2 STI clinics in Lilongwe, Malawi, between 2015 and 2019.

Methods: We used binomial regression to estimate the effect of the combination intervention vs.

Synthesis of end-user research to inform future multipurpose prevention technologies in sub-Saharan Africa: a scoping review.

Introduction: Women in sub-Saharan Africa (SSA) experience disproportionately high rates of HIV infection and unintended pregnancy compared to their age-matched counterparts in other regions of the world. Multipurpose prevention technologies (MPTs) that offer protection against HIV and unintended pregnancy in a single product stand to address these dual sexual and reproductive health needs simultaneously. The aim of this scoping review is to identify factors that are important for optimizing the likelihood of MPT adoption by end users in SSA.

Depression, Alcohol Use, and Sexual Behaviors by HIV Infection Stage and Diagnosis Timing Among STI Clinic Patients in Lilongwe, Malawi.

Understanding depression, alcohol use, and sexual behaviors according to HIV infection stage and diagnosis timing is important for HIV prevention efforts. We enrolled persons with recent infection and diagnosis (i.e.

Relationships Between Stress-Responsive Biomarkers, ART Adherence, and Viral Suppression Among Adolescent Girls and Young Women Living With HIV in South Africa: An HPTN 068 Analysis.

Background: Adolescent girls and young women (AGYW) living with HIV who have higher stress levels may be at risk of stress-related biological alterations, which could influence HIV progression and adherence to antiretroviral therapy (ART).

Setting: We aimed to estimate associations among stress-responsive biomarkers, ART adherence, and viral suppression in AGYW living with HIV in South Africa. We also hypothesized that psychosocial stressors [eg, depression, food insecurity, low socioeconomic status (SES), and HSV-2] would be associated with higher biomarker levels.

Lessons Learned in Centering Youth Voices in HIV Prevention: The Adolescent Health Working Group.

Background: There remains critical need for community-based approaches to HIV prevention which center youth voices and needs.

Objectives: We established an adolescent health working group (AHWG) to convene youth, parents, providers, and advocates in agenda-setting for interventions to increase pre-exposure prophylaxis uptake in Durham.

Methods: Our three study phases included six AHWG meetings from 2019 to 2020, youth-only meetings guided by a participatory engagement framework (Youth Generate and Organize), and interviews (n=13) and surveys with youth in the community (N=87).

HIV Related Behaviors Among Male Partners of Adolescent Girls and Young Women in Rural South Africa.

Improving men's engagement in HIV prevention is not only essential for reducing their own HIV risk but also the risk of transmitting HIV to their female partners. We conducted a cross-sectional survey using a population-based sample of men (age 18-30) who reported being a partner of an adolescent girls and young women (AGYW) in South Africa (N = 2827). We used logit-binomial regression models to examine associations among men's partnership characteristics, HIV risk perceptions, and HIV-related behaviors and examine differences by male partner age (younger men (18-24) vs.

Making the Case for Joint Decision-Making in Future Multipurpose Prevention Technology (MPT) Choice: Qualitative Findings on MPT Attribute Preferences from the CUPID Study (MTN-045).

Introduction: Young women in sub-Saharan Africa account for two-thirds of all new HIV infections and face high rates of unintended pregnancy. Multipurpose prevention technologies (MPTs) are promising products under development that are designed to simultaneously prevent HIV and unintended pregnancy. Since MPTs will be used in the context of sexual relationships, ensuring acceptability and use requires understanding the role of male partners in MPT use decision-making.

In vitro assessment of varying peptide surface density on the suppression of angiogenesis by micelles displaying αvβ3 blocking peptides.

Ligand targeted therapy (LTT) is a precision medicine strategy that can selectively target diseased cells while minimizing off-target effects on healthy cells. Integrin-targeted LTT has been developed recently for angiogenesis-related diseases. However, the clinical success is based on the optimal design of the nanoparticles for inducing receptor clustering within the cell membrane.

Couples' decision making regarding the use of multipurpose prevention technology (MPT) for pregnancy and HIV prevention.

We conducted a secondary analysis of discrete choice experiment (DCE) data from 395 couples enrolled in the Microbicide Trials Network (MTN)-045/CUPID study in Uganda and Zimbabwe to understand couple decision making around choice of multipurpose prevention technologies (MPTs) to prevent both HIV and pregnancy. Members of couples completed the same DCE, first separately then jointly, choosing between two hypothetical MPTs in a series of nine questions. Most couples either had similar preferences at the outset or had equal decision-making around MPTs (62%).

Partnership Dynamics and HIV-Related Sexual Behaviors Among Adolescent Mothers in South Africa: A Longitudinal Analysis of HIV Prevention Trials Network 068 Data.

Purpose: In South Africa, adolescent mothers have a three times higher risk of HIV acquisition than nonadolescent mothers. Yet, limited evidence exists regarding how early childbearing may affect HIV risk. A better understanding of adolescent mothers' partnership dynamics and sexual behaviors is critical to tailoring interventions to prevent new infections.

Probable perinatal depression and social support among women enrolled in Malawi's Option B+ Program: A longitudinal analysis.

Background: Malawi's PMTCT Option B+ program has expanded the reach of ART services among pregnant and breastfeeding women, but retention in lifelong HIV care remains challenging. Given that depression can undermine retention, it is important to understand how depression changes over the perinatal period, varies across treatment and retention groups, and could be buffered by social support.

Methods: Data are from an observational study conducted among women enrolled in Malawi's PMTCT Option B+ program.

Pitfalls of AHI system of severity grading in obstructive sleep apnoea.

Obstructive sleep apnoea (OSA) is the major underlying co-morbidity in many of the non-communicable diseases (NCD) due to obesity as a common risk factor. Incidence and prevalence of OSA is on the constant rise ever since this entity came to forefront three decades ago. Precise treatment of underlying OSA is extremely important in major NCDs like diabetes mellitus, hypertension, endocrine disorders and vascular diseases.

This brief report identifies challenges, strategies, and lessons learned from transitioning our three-phased, community-engaged HIV prevention project with Black youth to a remote format during COVID-19. The project involved (1) building a community-academic partnership on youth sexual health, (2) participatory youth workshops, and (3) youth surveys and interviews about HIV prevention.

HIV and Herpes Simplex Virus Type 2 Incidence Among Adolescent Mothers in South Africa: A Longitudinal Analysis of HIV Prevention Trials Network 068 Data.

Background: Adolescent motherhood is common in South Africa and occurs against a backdrop of high HIV risk. While childbearing during adolescence may result in social and economic strain that may negatively impact health, there has been limited study of whether adolescent motherhood increases the risk of HIV or herpes simplex virus type 2 (HSV-2) acquisition or engagement in high-risk sexual partnerships.

Setting: Data are from HIV Prevention Trials Network 068, a longitudinal conditional cash transfer study of adolescent girls and young women (age, 13-23) in rural South Africa.

Using Participatory Methods to Assess PrEP Interest and Uptake Among Young People Living in the Southeastern US: A Mixed Methods Assessment.

Adolescents and young adults (AYA; 13-24 years-old) comprise 22% of new HIV infections in the United States (US), most of whom live in the South. We used the situated-Information, Motivation, Behavioral skills (sIMB) model to identify priorities for intervention on multi-level factors that influence HIV preventive care among Black AYA in Durham, North Carolina. We conducted two participatory workshops (ages 13-17, N = 6; ages 18-24, N = 7) to engage youth about how to discuss HIV.

Effects of Early Social Bonds on Adolescent Trajectories of Sexual Risk Behaviors Among South African Girls.

The goal of this manuscript is to advance HIV risk behavior prevention efforts for South African adolescent girls by identifying distinct trajectory patterns across multiple behavioral domains for adolescent and young adults. We draw from a sample of N = 1070 adolescent girls from South Africa who were between the ages of 13-15 at baseline. Participants were followed across 6 waves of data collection between 2011 and 2019.

Contraceptive Conversations among Adolescent Girls and Young Women and Their Partners, Peers, and Older Female Family Members in Lilongwe, Malawi: A QualitativeAnalysis.

In sub-Saharan Africa, adolescent girls and young women (AGYW) have high levels of unmet need for contraception, particularly those who are unmarried or nulliparous. Conversations with partners, peers, and family members influence AGYW contraceptive decision-making yet little is known about conversation content and impact or how they vary by relationship status and parity. This paper draws on qualitative data from 60 AGYW (aged 15-24) participating in a sexual and reproductive health study in Malawi to examine contraceptive conversation patterns among participants and their social ties.
