Repetitive transcranial magnetic stimulation in the treatment of opioid use disorder: A narrative review.

It is estimated that over 16 million people are living with opioid use disorder (OUD) worldwide, with 2.1 million people in the United States. Opioid addiction is theorized to be associated with strong dopaminergic response to opioid receptor stimulations that contributes to reward-seeking behaviors and individuals' experiences with opioids.

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.

Results From a Pilot Study of an Automated Directly Observed Therapy Intervention Using Artificial Intelligence With Conditional Economic Incentives Among Young Adults With HIV.

Background: Despite improvements in antiretroviral therapy (ART) availability, suboptimal adherence is common among youth with HIV (YWH) and can increase drug resistance and poor clinical outcomes. Our study examined an innovative mobile app-based intervention that used automated directly observed therapy (aDOT) using artificial intelligence, along with conditional economic incentives (CEIs) to improve ART adherence and enhance viral suppression among YWH.

Setting: We conducted a pilot study of the aDOT-CEI intervention, informed by the operant framework of Key Principles in Contingency Management Implementation, to improve ART adherence among YWH (18-29) in California and Florida who had an unsuppressed HIV viral load.

Youth Ending the HIV Epidemic (YEHE): Protocol for a pilot of an automated directly observed therapy intervention with conditional economic incentives among young adults with HIV.

Background: Young adults have a disproportionately high rate of HIV infection, high rates of attrition at all stages of the HIV care continuum, and an elevated probability of disease progression and transmission. Tracking and monitoring objective measures of antiretroviral therapy (ART) adherence in real time is critical to bolster the accuracy of research data, support adherence, and improve clinical outcomes. However, adherence monitoring often relies on self-reported and retrospective data or requires additional effort from providers to understand individual adherence patterns.

Durable immunity to SARS-CoV-2 in both lower and upper airways achieved with a gorilla adenovirus (GRAd) S-2P vaccine in non-human primates.

SARS-CoV-2 continues to pose a global threat, and current vaccines, while effective against severe illness, fall short in preventing transmission. To address this challenge, there's a need for vaccines that induce mucosal immunity and can rapidly control the virus. In this study, we demonstrate that a single immunization with a novel gorilla adenovirus-based vaccine (GRAd) carrying the pre-fusion stabilized Spike protein (S-2P) in non-human primates provided protective immunity for over one year against the BA.

iVY: protocol for a randomised clinical trial to test the effect of a technology-based intervention to improve virological suppression among young adults with HIV in the USA.

Introduction: Young adults with HIV (YWH) experience worse clinical outcomes than adults and have high rates of substance use (SU) and mental illness that impact their engagement in care and adherence to antiretroviral therapy (ART). The intervention for Virologic Suppression in Youth (iVY) aims to address treatment engagement/adherence, mental health (MH) and SU in a tailored manner using a differentiated care approach that is youth friendly. Findings will provide information about the impact of iVY on HIV virological suppression, MH and SU among YWH who are disproportionately impacted by HIV and at elevated risk for poor health outcomes.

Intimate partner violence is associated with cytomegalovirus among young women in rural South Africa: An HPTN 068 analysis.

Stressful life circumstances (e.g. violence and poverty) have been associated with elevated biomarkers, including C-reactive protein (CRP), cytomegalovirus (CMV), and herpes simplex virus type-1 (HSV-1), among older adults in high-income settings.

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.

Examining Associations Between Mental Health, IPV Exposure, HIV Risk Behaviors, and PrEP Use in South African Women: An Analysis of Data from the Charisma Study.

Intimate partner violence (IPV) has been associated with poorer mental health outcomes and increased human immunodeficiency virus (HIV) risk behaviors. We examine the relations between IPV, mental health symptomology (defined as psychological distress and alcohol misuse), and engagement in HIV risk behaviors among a sample of South African women who participated in a randomized controlled trial of CHARISMA, an intervention to increase women's agency to use oral pre-exposure prophylaxis (PrEP) safely and consistently as well as mitigate relationship challenges. We also examined the impact of trial participation on women's mental health, as well as the impact of psychological distress on the effectiveness of the CHARISMA intervention.

High time-resolution measurements of ultrafine and fine woodsmoke aerosol number and surface area concentrations in biomass burning kitchens: A case study in Western Kenya.

Indoor air pollution associated with biomass combustion for cooking remains a significant environmental health challenge in rural regions of sub-Saharan Africa; however, routine monitoring of woodsmoke aerosol concentrations continues to remain sparse. There is a paucity of field data on concentrations of combustion-generated ultrafine particles, which efficiently deposit in the human respiratory system, in such environments. Field measurements of ultrafine and fine woodsmoke aerosol (diameter range: 10-2500 nm) with field-portable diffusion chargers were conducted across nine wood-burning kitchens in Nandi County, Kenya.

mRNA-1273 or mRNA-Omicron boost in vaccinated macaques elicits similar B cell expansion, neutralizing responses, and protection from Omicron.

SARS-CoV-2 Omicron is highly transmissible and has substantial resistance to neutralization following immunization with ancestral spike-matched vaccines. It is unclear whether boosting with Omicron-matched vaccines would enhance protection. Here, nonhuman primates that received mRNA-1273 at weeks 0 and 4 were boosted at week 41 with mRNA-1273 or mRNA-Omicron.

The CHARISMA Randomized Controlled Trial: A Relationship-Focused Counseling Intervention Integrated Within Oral PrEP Delivery for HIV Prevention Among Women in Johannesburg, South Africa.

Background: Consistent use of oral pre-exposure prophylaxis (PrEP) has been a challenge among women, particularly when in relationships with lack of partner support or intimate partner violence (IPV).

Methods: We conducted a randomized controlled trial (RCT) of an empowerment counseling intervention called "CHARISMA" delivered to women within a PrEP demonstration project in Johannesburg, South Africa. The trial tested the effectiveness of CHARISMA to increase PrEP adherence; decrease social harms and IPV; and improve partnership dynamics (eg, communication, disclosure and support) compared with those who received the standard of care counselling support and referrals.

Primary exposure to SARS-CoV-2 variants elicits convergent epitope specificities, immunoglobulin V gene usage and public B cell clones.

An important consequence of infection with a SARS-CoV-2 variant is protective humoral immunity against other variants. The basis for such cross-protection at the molecular level is incompletely understood. Here we characterized the repertoire and epitope specificity of antibodies elicited by Beta, Gamma and ancestral variant infection and assessed their cross-reactivity to these and the more recent Delta and Omicron variants.

Protection from SARS-CoV-2 Delta one year after mRNA-1273 vaccination in rhesus macaques coincides with anamnestic antibody response in the lung.

mRNA-1273 vaccine efficacy against SARS-CoV-2 Delta wanes over time; however, there are limited data on the impact of durability of immune responses on protection. Here, we immunized rhesus macaques and assessed immune responses over 1 year in blood and upper and lower airways. Serum neutralizing titers to Delta were 280 and 34 reciprocal ID at weeks 6 (peak) and 48 (challenge), respectively.

Protection from SARS-CoV-2 Delta one year after mRNA-1273 vaccination in nonhuman primates is coincident with an anamnestic antibody response in the lower airway.

Protection against SARS-CoV-2 Beta variant in mRNA-1273 vaccine-boosted nonhuman primates.

Neutralizing antibody responses gradually wane against several variants of concern (VOCs) after vaccination with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine messenger RNA-1273 (mRNA-1273). We evaluated the immune responses in nonhuman primates that received a primary vaccination series of mRNA-1273 and were boosted about 6 months later with either homologous mRNA-1273 or heterologous mRNA-1273.β, which encompasses the spike sequence of the B.

Integration of a Relationship-focused Counseling Intervention with Delivery of the Dapivirine Ring for HIV Prevention to Women in Johannesburg: Results of the CHARISMA Pilot Study.

Biomedical, female-initiated HIV prevention methods can help reduce disproportionately high HIV rates among women in sub-Saharan Africa, but male partner resistance and intimate partner violence (IPV) may impact ability to ensure effective use. To support consistent use of the dapivirine vaginal ring (VR), we pilot-tested the impact of the CHARISMA relationship counseling intervention ("CHARISMA") with women enrolled in the multi-site open-label Microbicide Trials Network (MTN) 025/HOPE trial at the Wits Reproductive Health and HIV Research Institute (Wits RHI) site in Johannesburg, South Africa. Lay counselors used a 42-item tool with five subscales to assess relationships and IPV and provide tailored counseling at enrolment, followed by a booster counselling session at Month 1 and follow-up checks at Months 3 and 6.

Protection against SARS-CoV-2 Beta Variant in mRNA-1273 Boosted Nonhuman Primates.

Unlabelled: Neutralizing antibody responses gradually wane after vaccination with mRNA-1273 against several variants of concern (VOC), and additional boost vaccinations may be required to sustain immunity and protection. Here, we evaluated the immune responses in nonhuman primates that received 100 µg of mRNA-1273 vaccine at 0 and 4 weeks and were boosted at week 29 with mRNA-1273 (homologous) or mRNA-1273.β (heterologous), which encompasses the spike sequence of the B.

Giving voice to the end-user: input on multipurpose prevention technologies from the perspectives of young women in Kenya and South Africa.

Unintended pregnancy and unmet need for modern contraception contribute substantially to reproductive health disparities globally. In sub-Saharan Africa they occur in contexts of disproportionately high rates of HIV infection. Multipurpose prevention technologies (MPTs) can address HIV and pregnancy prevention needs in a single "2-in-1" product; however, few studies have solicited end-user views to inform design of new MPTs.

Ultrapotent antibodies against diverse and highly transmissible SARS-CoV-2 variants.

The emergence of highly transmissible SARS-CoV-2 variants of concern (VOCs) that are resistant to therapeutic antibodies highlights the need for continuing discovery of broadly reactive antibodies. We identified four receptor binding domain-targeting antibodies from three early-outbreak convalescent donors with potent neutralizing activity against 23 variants, including the B.1.

Real-Time Measurements of Gas-Phase Trichloramine (NCl) in an Indoor Aquatic Center.

NCl is formed as a disinfection byproduct in chlorinated swimming pools and can partition between the liquid and gas phases. Exposure to gas-phase NCl has been linked to asthma and can irritate the eyes and respiratory airways, thereby affecting the health and athletic performance of swimmers. This study involved an investigation of the spatiotemporal dynamics of gas-phase NCl in an aquatic center during a collegiate swim meet.

High-throughput, single-copy sequencing reveals SARS-CoV-2 spike variants coincident with mounting humoral immunity during acute COVID-19.

Tracking evolution of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) within infected individuals will help elucidate coronavirus disease 2019 (COVID-19) pathogenesis and inform use of antiviral interventions. In this study, we developed an approach for sequencing the region encoding the SARS-CoV-2 virion surface proteins from large numbers of individual virus RNA genomes per sample. We applied this approach to the WA-1 reference clinical isolate of SARS-CoV-2 passaged in vitro and to upper respiratory samples from 7 study participants with COVID-19.

Acceptability and feasibility of the CHARISMA counseling intervention to support women's use of pre-exposure prophylaxis: results of a pilot study.

Background: Women may need or seek male partner approval to safely and consistently use oral antiretroviral pre-exposure prophylaxis (PrEP) or vaginal microbicides. We developed CHARISMA, a counseling intervention to support women's relationships and their ability to consistently use HIV prevention products.

Methods: In a pilot study with 95 female participants in Johannesburg, South Africa, lay counselors implemented CHARISMA, assessing participants' relationship(s) with their male partner(s) and barriers or facilitators to HIV prevention method use, and then providing tailored, interactive counseling.
