Implementation of an Opt-out and Rapid Point-Of-Care Syphilis Testing Program for Pregnant Patients Presenting to the Emergency Department.

Background: Adult and congenital syphilis rates are rising in the US. The aim of this pre- and post-implementation study was to determine whether implementation of an opt-out laboratory-based and rapid syphilis point-of-care testing program in the emergency department (ED) improves the detection and treatment of syphilis during pregnancy in a high-prevalence region.

Methods: This pre-and post-implementation study was conducted at the University of Texas Health Science Center, Houston, TX.

Perspectives on a peer-driven intervention to promote pre-exposure prophylaxis (PrEP) uptake among men who have sex with men in southern New England: a qualitative study.

Background: Pre-exposure prophylaxis (PrEP) is a highly effective pharmaceutical intervention that prevents HIV infection, but PrEP uptake across the US has been slow among men who have sex with men (MSM), especially among Black/African American (B/AA) and Hispanic /Latino (H/L) MSM. This study investigates the acceptability and essential components of a peer-driven intervention (PDI) for promoting PrEP uptake among MSM, with a specific focus on B/AA and H/L communities.

Methods: We conducted 28 semi-structured, qualitative interviews with MSM in southern New England to explore the components of a PDI, including attitudes, content, and effective communication methods.

CDC Clinical Guidelines on the Use of Doxycycline Postexposure Prophylaxis for Bacterial Sexually Transmitted Infection Prevention, United States, 2024.

No vaccines and few chemoprophylaxis options exist for the prevention of bacterial sexually transmitted infections (STIs) (specifically syphilis, chlamydia, and gonorrhea). These infections have increased in the United States and disproportionately affect gay, bisexual, and other men who have sex with men (MSM) and transgender women (TGW). In three large randomized controlled trials, 200 mg of doxycycline taken within 72 hours after sex has been shown to reduce syphilis and chlamydia infections by >70% and gonococcal infections by approximately 50%.

Summary of the Centers for Disease Control and Prevention/National Institute of Allergy and Infectious Diseases Joint Workshop on Genital Herpes: 3-4 November 2022.

Genital herpes is caused by infection with herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) and currently has no cure. The disease is the second-most common sexually transmitted infection in the United States, with an estimated 18.6 million prevalent genital infections caused by HSV-2 alone.

-Substitution of Perylene Bisimides with Bidentate Nucleophiles: The Case of Aryloxide Anions.

In this study, we delve into the regioselectivity of nucleophilic reactions involving brominated perylene bisimides (PBIs) and various bidentate aryloxide anions, previously associated with an S1 mechanism. We present herein a new perspective, suggesting that a single-electron-transfer aromatic nucleophilic substitution (SeT-SAr) mechanism is a more plausible scenario. Our study reveals the favorable impact of photostimulation on reaction yields, making our method a convenient approach for accessing arylated PBIs.

Perspectives on HIV pre-exposure prophylaxis (PrEP) implementation in Mississippi among Black women and clinical staff: Recommendations for clinical trauma-informed programs.

Intimate partner violence (IPV) can constraint Black women's ability to prioritize and access Human Immunodeficiency Virus (HIV) pre-exposure prophylaxis (PrEP) services. Recent research has called for the development of trauma-informed PrEP implementation programs to improve the delivery of PrEP to Black cisgender women; however, many PrEP-prescribing settings do not reflect this recommendation. The current study sought to identify key components to develop a trauma-informed PrEP implementation program for Black cisgender women and clinical staff.

Vital Signs: Missed Opportunities for Preventing Congenital Syphilis - United States, 2022.

Introduction: Congenital syphilis cases in the United States increased 755% during 2012-2021. Syphilis during pregnancy can lead to stillbirth, miscarriage, infant death, and maternal and infant morbidity; these outcomes can be prevented through appropriate screening and treatment.

Methods: A cascading framework was used to identify and classify missed opportunities to prevent congenital syphilis among cases reported to CDC in 2022 through the National Notifiable Diseases Surveillance System.

Affirming and Inclusive Care Training for Medical Students and Residents to Reduce Health Disparities Experienced by Sexual and Gender Minorities: A Systematic Review.

Purpose: Providing inclusive and comprehensive gender-affirming care is critical to reducing health disparities (gaps in care) experienced by sexual and gender minorities (SGM). Currently, little is known about how medical students and residents are being trained to address the health needs of SGM persons or of the most effective methods.

Methods: We conducted a systematic review of the research literature from 2000 to 2020 on the effectiveness of teaching medical students and residents on knowledge, attitudes, and skills in addressing the health of SGM persons and the strength of the research sample, design, and methods used.

Quantitative prediction of excited-state decay rates for radical anion photocatalysts.

We present a computational approach for predicting key properties of organic radical anions, including excited-state lifetimes and redox potentials. The approach shows good agreement with experimental data and has potential for screening to facilitate the rational design of photocatalysts.

"Make it more than a pill, make it an experience of health:" results from an open pilot intervention to retain young African American men who have sex with men in PrEP care.

Uptake and retention in clinical care for pre-exposure prophylaxis (PrEP) is suboptimal, particularly among young African American men who have sex with men (MSM) in the Deep South. We conducted a two-phase study to develop and implement an intervention to increase PrEP persistence. In Phase I, we conducted focus groups with 27 young African American MSM taking PrEP at a community health center in Jackson, Mississippi to elicit recommendations for the PrEP persistence intervention.

Persistence in a pharmacist-led, same-day PrEP program in Mississippi: a mixed-methods study.

Introduction: Mississippi has one of the highest rates of HIV in the United States but low PrEP uptake. Understanding patterns of PrEP use can improve PrEP initiation and persistence.

Methods: This is a mixed-method evaluation of a PrEP program in Jackson, Mississippi.

HIV Incidence Among Individuals Accessing Pre-Exposure Prophylaxis in Jackson, Mississippi.

Although pre-exposure prophylaxis (PrEP) is an efficacious biomedical intervention, the effectiveness of same-day PrEP programs has not been widely studied. We utilized data from three of the four largest PrEP providers in Mississippi from September 2018 to September 2021 linked to the Mississippi State Department of Health's Enhanced HIV/AIDS reporting system. HIV diagnosis was defined as testing newly positive for HIV at least 2 weeks after the initial PrEP visit.

PrEP Acceptance among Eligible Patients Attending the Largest PrEP Clinic in Jackson, Mississippi.

Compared to other states in the United States, Mississippi has the lowest uptake of PrEP relative to the number of people newly diagnosed with HIV in the state. Open Arms Healthcare Center is the largest provider of PrEP in Mississippi, and has systematically documented PrEP eligibility, offers, and acceptance (ie, agreed to undergo a clinical PrEP evaluation) from 2017 to mid-2020. In encounter-based analyses, we examined factors associated with PrEP acceptance.

Family-Related Factors and HIV-Related Outcomes Among Black Young Men Who Have Sex with Men in Mississippi.

Given their disproportionate HIV incidence, there is a critical need to identify factors related to HIV risk among Black young men who have sex with men (YMSM) in the southeastern United States. This study investigated the association of family factors and HIV-related outcomes among Black YMSM in Mississippi ages 14-20 (n = 72). Multivariable regression models evaluated associations of family factors and outcomes.

Telehealth Services: Implications for Enhancing Sexually Transmitted Infection Prevention.

In the United States, sexually transmitted infections (STIs) are among the most persistent threats to health equity. Increasing access to STI prevention and control services through the provision of Remote Health and Telehealth can improve sexual health outcomes. Telehealth has been shown to increase access to care and even improve health outcomes.

Factors associated with suboptimal retention in HIV pre-exposure prophylaxis care among men who have sex with men.

Despite the efficacy of HIV pre-exposure prophylaxis (PrEP), retention in care in the United States remains suboptimal. The goal of this study was to explore factors that lead to suboptimal retention in PrEP care for men who have sex with men (MSM) in real-world clinical settings in the United States. Trained interviewers conducted semi-structured interviews with MSM (N = 49) from three clinics who had been engaged in PrEP care in the Midwest (n = 15), South (n = 15), and Northeast (n = 19) geographic regions and had experienced a lapse in PrEP use.

Patterns of Pre-exposure Prophylaxis (PrEP) Use in a Population Accessing PrEP in Jackson, Mississippi.

Pre-exposure prophylaxis (PrEP) persistence is suboptimal in the United States. In the Deep South, a region with high rates of new HIV diagnosis, patterns of PrEP discontinuation remain unexplored. We evaluated data from a clinic-based PrEP program in Jackson, Mississippi and included patients initiating PrEP between August 2018 and April 2021.

Pre-exposure Prophylaxis Discontinuation During the COVID-19 Pandemic Among Men Who Have Sex With Men in a Multisite Clinical Cohort in the United States.

Background: The coronavirus disease 2019 (COVID-19) pandemic continues to put strain on health systems in the United States, leading to significant shifts in the delivery of routine clinical services, including those offering HIV pre-exposure prophylaxis (PrEP). We aimed to assess whether individuals discontinued PrEP use at higher rates during the COVID-19 pandemic and the extent to which disruptions to usual clinical care were mitigated through telehealth.

Methods: Using data from an ongoing prospective cohort of men who have sex with men (MSM) newly initiating PrEP in 3 mid-sized cities (n = 195), we calculated the rate of first-time discontinuation of PrEP use in the period before the COVID-19 pandemic and during the COVID-19 pandemic and compared these rates using incidence rate ratios (IRRs).

HIV and Sexually Transmitted Infections Among Persons with Monkeypox - Eight U.S. Jurisdictions, May 17-July 22, 2022.

High prevalences of HIV and other sexually transmitted infections (STIs) have been reported in the current global monkeypox outbreak, which has affected primarily gay, bisexual, and other men who have sex with men (MSM) (1-5). In previous monkeypox outbreaks in Nigeria, concurrent HIV infection was associated with poor monkeypox clinical outcomes (6,7). Monkeypox, HIV, and STI surveillance data from eight U.

Chalcogen Atoms as Electron Donors in Proton-Coupled Electron Transfer Reactions.

Proton-coupled electron transfer (PCET) reactions are crucial for the optimal functioning of a broad scope of chemical and biological processes. In this report, we present an unprecedented type of concerted PCET (cPCET), in which a chalcogen atom acts as the electron donor. The nature of this mechanism is key for understanding the reactivity of different radical-trapping antioxidants having heavy chalcogens (S, Se, or Te) in their structures.
