Exploring Racial Disparities in Awareness and Perceptions of Oncology Clinical Trials: Cross-Sectional Analysis of Baseline Data From the mychoice Study.

Background: Black/African American adults are underrepresented in oncology clinical trials in the United States, despite efforts at narrowing this disparity.

Objective: This study aims to explore differences in how Black/African American oncology patients perceive clinical trials to improve support for the clinical trial participation decision-making process.

Methods: As part of a larger randomized controlled trial, a total of 244 adult oncology patients receiving active treatment or follow-up care completed a cross-sectional baseline survey on sociodemographic characteristics, clinical trial knowledge, health literacy, perceptions of cancer clinical trials, patient activation, patient advocacy, health care self-efficacy, decisional conflict, and clinical trial intentions.

Vaccination uptake in LGBTQ adults in two US states: Findings from the QVax study.

Objectives: Lesbian, gay, bisexual, transgender, queer and other (LGBTQ+) individuals face numerous health disparities, including higher rates of chronic diseases and sexually transmitted infections, partly due to marginalization, discrimination, and a healthcare system often unprepared to meet their specific needs. Despite the importance of vaccination in preventing these health issues, vaccination patterns in LGBTQ+ populations remain under-researched, with limited data available due to the absence of sexual orientation and gender identity information on most healthcare forms. As such, we sought to understand vaccine uptake among LGBTQ+ individuals living in New Jersey and New York for 7 primary adult vaccines.

A magnetar giant flare in the nearby starburst galaxy M82.

Magnetar giant flares are rare explosive events releasing up to 10 erg in gamma rays in less than 1 second from young neutron stars with magnetic fields up to 10 G (refs. ). Only three such flares have been seen from magnetars in our Galaxy and in the Large Magellanic Cloud in roughly 50 years.

Oncologists' perceptions of tumor genomic profiling and barriers to communicating secondary hereditary risks to African American cancer patients.

Background: Tumor genomic profiling (TGP) identifies targets for precision cancer treatments, but also secondary hereditary risks. Oncologists are poorly trained to communicate the results of TGP, especially among patients with lower health literacy, poorer genetics knowledge, and higher mistrust. African American (AA) patients are especially vulnerable to poor understanding due to significant cancer disparities and lower uptake of TGP.

Identifying Key Factors to PrEP Initiation and Persistence Among YMSM Through Focus Groups and Surveys in Two High-Priority Settings.

Cisgender men are diagnosed with HIV at a rate four times greater than cisgender women, with 71% of infections attributed to male-male sexual contact. Despite expanding accessibility, pre-exposure prophylaxis (PrEP) for HIV prevention is initiated by only 30% of people with PrEP indications. Five focus groups with 42 young men who have sex with men from New York and Alabama were conducted to identify key factors to PrEP initiation and persistence.

Heavy-element production in a compact object merger observed by JWST.

The mergers of binary compact objects such as neutron stars and black holes are of central interest to several areas of astrophysics, including as the progenitors of gamma-ray bursts (GRBs), sources of high-frequency gravitational waves (GWs) and likely production sites for heavy-element nucleosynthesis by means of rapid neutron capture (the r-process). Here we present observations of the exceptionally bright GRB 230307A. We show that GRB 230307A belongs to the class of long-duration GRBs associated with compact object mergers and contains a kilonova similar to AT2017gfo, associated with the GW merger GW170817 (refs.

The Relationship Between Gender-Affirming Procedures, Body Image Quality of Life, and Gender Affirmation.

This study explored whether self-reported barriers to accessing a health care provider, gender-affirming procedures, and relevant psychosocial measures were related to experienced gender affirmation in a cross-sectional sample of trans individuals (=101). Body image quality of life [=0.181, (4.

The relationship of PrEP beliefs to perceived personal, interpersonal and structural benefits and barriers to PrEP use in women who inject drugs.

Background: Women who inject drugs (WWID) have significant biological, behavioral, and gender-based barriers to accessing HIV prevention services, including Pre-Exposure Prophylaxis (PrEP) medication. Little is known about how beliefs about PrEP impact both perceived barriers and benefits of PrEP use and how they may be related to the decision-making process.

Methods: Surveys were conducted with 100 female clients of a large syringe services program in Philadelphia, Pennsylvania.

Acceptability and Feasibility of Providing Adherence Feedback Based on Tenofovir Diphosphate in Dried Blood Spots: Results from a Pilot Study Among Patients and Providers in Cape Town, South Africa.

Tenofovir diphosphate (TFV-DP) concentrations in dried blood spots (DBS) predict viral breakthrough, but their use remains understudied in real-world clinic settings. This pilot study examined acceptability, feasibility, and initial adherence outcomes of providing adherence feedback using TFV-DP concentrations on patient- and provider-levels in Cape Town, South Africa. We enrolled 60 persons with HIV (PWH) receiving tenofovir-containing ART attending a primary health clinic.

Gigaelectronvolt emission from a compact binary merger.

An energetic γ-ray burst (GRB), GRB 211211A, was observed on 11 December 2021. Despite its long duration, typically associated with bursts produced by the collapse of massive stars, the observation of an optical-infrared kilonova points to a compact binary merger origin. Here we report observations of a significant (more than five sigma) transient-like emission in the high-energy γ-rays of GRB 211211A (more than 0.

Biological, Behavioral, and Demographic Drivers of Recent Syphilis Infection Among Emerging Adult Sexual Minority Men in New York City: The P18 Cohort Study.

The rate of syphilis infections among sexual minority men (SMM) has continued to increase in recent decades. As such, this analysis sought to identify demographic, biological, and behavioral factors associated with recent syphilis infection in emerging adult SMM. Data were drawn from a 3-year cohort study of emerging adult SMM ( = 665), from July 2014 to March 2019.

The Role of Medical Mistrust in Concerns about Tumor Genomic Profiling among Black and African American Cancer Patients.

Tumor genomic profiling (TGP) is used in oncology practice to optimize cancer treatment and improve survival rates. However, TGP is underutilized among Black and African American (AA) patients, creating potential disparities in cancer treatment outcomes. Cost, accuracy, and privacy are barriers to genetic testing, but medical mistrust (MM) may also influence how Black and AA cancer patients perceive TGP.

Post-Exposure Prophylaxis and Methamphetamine Use among Young Sexual Minority Men: The P18 Cohort Study.

Methamphetamine use is associated with increased risk of HIV infection among young sexual minority men (SMM). Post-exposure prophylaxis (PEP) is an effective strategy for individuals who are exposed to HIV, but there is limited research about PEP use among young SMM and its relationship with methamphetamine use. This study analyzes the association between ever PEP use and recent methamphetamine use among young SMM in New York City, using cross-sectional data from the P18 Cohort Study ( = 429).

Changing Behavior, Attitudes, and Beliefs About Food Safety: A Scoping Review of Interventions Across the World and Implications for Empowering Consumers.

Foodborne illnesses are a global public health issue. Responsibility to prevent foodborne disease is shared by many actors along the food supply chain, including consumers. However, consumers often lack knowledge about food safety and behaviors that can reduce risk.

Exploring barriers and facilitators to PrEP use among transgender women in two urban areas: implications for messaging and communication.

Background: Trans women are at increased risk for HIV infection yet are less likely to use pre-exposure prophylaxis (PrEP) medication as a preventive measure. PrEP messaging and marketing has focused on men who have sex with men (MSM) or included trans women as a subset of MSM, ignoring the potential barriers to PrEP use unique to trans women. Little is known about how this group conceptualizes PrEP, what knowledge gaps still exist, and how trans women believe PrEP should be communicated to increase use.

SARS-CoV-2 Vaccination Hesitancy and Behaviors in a National Sample of People Living with HIV.

As COVID-19 vaccinations became available in early 2021, we collected data from a US national sample of 496 people living with HIV (PLWH) to assess COVID-19 vaccination uptake and attitudes. The study was cross-sectional, and data were collected using an online survey between March and May 2021. At the time, 64% of the participants received at least one dose of a COVID-19 vaccine.

Oncologists' Perceptions of Tumor Genomic Profiling and the Communication of Test Results and Risks.

Tumor genomic profiling (TGP) identifies genetic targets for precision cancer treatments. The complexity of TGP can expose gaps in oncologists' skills, complicating test interpretation and patient communication. Research on oncologists' use and perceptions of TGP could inform practice patterns and training needs.

Spectral index-flux relation for investigating the origins of steep decay in γ-ray bursts.

γ-ray bursts (GRBs) are short-lived transients releasing a large amount of energy (10 - 10 erg) in the keV-MeV energy range. GRBs are thought to originate from internal dissipation of the energy carried by ultra-relativistic jets launched by the remnant of a massive star's death or a compact binary coalescence. While thousands of GRBs have been observed over the last thirty years, we still have an incomplete understanding of where and how the radiation is generated in the jet.

Healthcare beliefs, health information seeking, and healthcare setting preferences among women who inject drugs by community supervision status.

Objective: Women on community supervision who inject drugs have significant unmet healthcare needs. However, it remains unclear how the intersection of community supervision and injection drug use influences healthcare experiences and service setting preferences. The present study examines whether the intersection of community supervision and injection drug use is associated with differences in women's healthcare beliefs, healthcare experiences, and service setting preferences.

Psychosocial Differences Between Transgender Individuals With and Without History of Nonsurgical Facial Injectables.

Background: Considerable research has explored psychosocial characteristics of individuals who seek aesthetic procedures as well as psychological changes experienced after successful treatment. Little research, however, has explored the experiences of transgender individuals who have undergone nonsurgical injectable procedures (NSIPs).

Objectives: This study examined theoretically relevant psychosocial characteristics of transgender individuals who have and have not undergone NSIPs.

Community Belonging and Attitudes Towards HIV Pre-Exposure Prophylaxis (PrEP) Among Transgender Women.

For transgender (trans) women, community belonging may play an important role in shaping perceptions of HIV Pre-exposure Prophylaxis (PrEP). A cluster analysis was performed using data obtained from a survey administered to 128 trans women residing in Philadelphia, PA and the San Francisco Bay area, CA. Six items assessing feelings of community belongingness among trans women produced three distinct clusters.

Exploring the Engagement of Racial and Ethnic Minorities in HIV Treatment and Vaccine Clinical Trials: A Scoping Review of Literature and Implications for Future Research.

HIV disproportionately impacts US racial and ethnic minorities but they participate in treatment and vaccine clinical trials at a lower rate than whites. To summarize barriers and facilitators to this participation we conducted a scoping review of the literature guided by the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. Studies published from January 2007 and September 2019 were reviewed.

"Take Charge, Get Cured": Pilot testing a targeted mHealth treatment decision support tool for methadone patients with hepatitis C virus for acceptability and promise of efficacy.

Hepatitis C (HCV) is a highly prevalent infection in current and former IV drug users. Current estimates indicate that over 70% of those in methadone maintenance treatment programs (MMTs) have HCV, but only 11% have initiated treatments despite availability of new treatments that are easily tolerated and can cure infection in about 8 weeks. We conducted a pilot randomized trial at four Philadelphia, PA MMTs to test acceptability, feasibility and promise of efficacy of our "Take Charge, Get Cured" mobile health (mHealth) treatment decision tool, developed through extensive formative work that included methadone patients' input and targeted directly to concerns of methadone patients with Hepatitis C (HCV).

Observation of inverse Compton emission from a long γ-ray burst.

Long-duration γ-ray bursts (GRBs) originate from ultra-relativistic jets launched from the collapsing cores of dying massive stars. They are characterized by an initial phase of bright and highly variable radiation in the kiloelectronvolt-to-megaelectronvolt band, which is probably produced within the jet and lasts from milliseconds to minutes, known as the prompt emission. Subsequently, the interaction of the jet with the surrounding medium generates shock waves that are responsible for the afterglow emission, which lasts from days to months and occurs over a broad energy range from the radio to the gigaelectronvolt bands.
