HIV incidence among transgender women remains high and disproportionately impacts young, Black, and Latina transgender women. Data on preferred PrEP modalities among this population are limited. Participants in The LITE Cohort completed a survey module on PrEP modality preferences during 24-month study visits.

HIV prevention for gay, bisexual, and other men who have sex with men (GBMSM) and transgender women (TGW) is critical to reducing health disparities and population HIV prevalence. To understand if different types of stigma impact engagement with HIV prevention services, we assessed associations between stigmas and use of HIV prevention services offered through an HIV prevention intervention. This analysis included 201 GBMSM and TGW enrolled in a prospective cohort offering a package of HIV prevention interventions.

Article Synopsis
  • In 1995, journalist Gary Taubes published an influential article critiquing nonrandomized epidemiologic research, which has since been cited over 1,000 times.
  • Taubes pointed out numerous associations in research that he believed had questionable validity, suggesting a need for more rigorous evaluation.
  • A recent systematic review of 53 discussed associations found that about 25% of those previously doubted are now accepted as causal, highlighting the evolving nature of public health research and the importance of reproducibility in epidemiology.

Introduction: In order to identify and evaluate candidate algorithms to detect COVID-19 cases in an electronic health record (EHR) database, this study examined and compared the utilization of acute respiratory disease codes from February to August 2020 versus the corresponding time period in the 3 years preceding.

Methods: De-identified EHR data were used to identify codes of interest for candidate algorithms to identify COVID-19 patients. The number and proportion of patients who received a SARS-CoV-2 reverse transcriptase polymerase chain reaction (RT-PCR) within ±10 days of the occurrence of the diagnosis code and patients who tested positive among those with a test result were calculated, resulting in 11 candidate algorithms.

Objectives: To examine the temporal patterns of patient characteristics, treatments used and outcomes associated with COVID-19 in patients who were hospitalised for the disease between January and 15 November 2020.

Design: Observational cohort study.

Setting: COVID-19 subset of the Optum deidentified electronic health records, including more than 1.

Background: Men who have sex with men (MSM) are at a disproportionate risk for HIV infection and common mental disorders worldwide. In the context of HIV, common mental disorders are important and are frequent drivers of suboptimal prevention and treatment outcomes. Mobile ecological momentary assessments (EMAs), or the repeated sampling of people's behaviors and psychological states in their daily lives using mobile phones, can clarify the triggers and HIV-related sequelae of depressive-anxious symptoms and contribute toward the design of ecological momentary interventions (EMIs) that cater to the contextually varying needs of individuals to optimize prevention and treatment outcomes.

Objective: To examine age, gender, and temporal differences in baseline characteristics and clinical outcomes of adult patients hospitalised with COVID-19.

Design: A cohort study using deidentified electronic medical records from a Global Research Network.

Setting/participants: 67 456 adult patients hospitalised with COVID-19 from the USA; 7306 from Europe, Latin America and Asia-Pacific between February 2020 and January 2021.

Background: Beginning March 2020, the COVID-19 pandemic has disrupted different aspects of life. The impact on children's rate of weight gain has not been analysed.

Methods: In this retrospective cohort study, we used United States (US) Electronic Health Record (EHR) data from Optum® to calculate the age- and sex- adjusted change in BMI (∆BMI) in individual 6-to-17-year-old children between two well child checks (WCCs).

Introduction: Amyotrophic lateral sclerosis (ALS) is a rare neurological disorder characterized by progressive deterioration of motor neurons. Assessment of the size/geographic distribution of the ALS population, including ALS with genetic origin, is needed to understand the burden of the disease and the need for clinical intervention and therapy.

Objectives: The main objective of this study was to estimate the number of prevalent and incident ALS cases overall and superoxide dismutase 1 (SOD1) and chromosome 9 open reading frame 72 (C9orf72) ALS in 22 countries across Europe (Belgium, France, Germany, Ireland, Italy, Netherlands, Norway, Russia, Spain, Sweden, and UK), North America (USA and Canada), Latin America (Argentina, Brazil, Colombia, Mexico, and Uruguay), and Asia (China, Japan, South Korea, and Taiwan).

Introduction: Globally, men who have sex with men (MSM) experience a disproportionate burden of mental health issues. While HIV service providers may possess the skills and relationships to provision mental health and psychosocial support (MHPSS) to this population, task-sharing models that integrate MHPSS into HIV contexts remain limited. The aim of this study was to explore the sociodemographic, psychological, and structural factors operant at the client and HIV service provider levels that shape MHPSS access and burden among MSM and opportunities for integration in Vietnam.

Background: Cancer incidence is increasing in Africa, and the majority of patients are diagnosed with advanced disease, limiting treatment options and survival. We sought to understand care patterns and factors contributing to delayed diagnosis and treatment initiation among patients with cancer in Botswana.

Patients And Methods: We recruited 20 patients who were enrolled in a prospective cancer cohort in Botswana to a qualitative substudy that explored cancer care pathways and factors affecting cancer care access and quality.

Background: Three-quarters of cancer deaths occur in resource-limited countries, and delayed presentation contributes to poor outcome. In Botswana, where more than half of cancers arise in HIV-infected individuals, we sought to explore predictors of timely oncology care and evaluate the hypothesis that engagement in longitudinal HIV care improves access.

Methods: Consenting patients presenting for oncology care from October 2010 to September 2014 were interviewed and their records were reviewed.

Within the broadly generalized HIV epidemic in Swaziland, men who have sex with men (MSM) have specific HIV acquisition and transmission risks. In the current era of expanding antiretroviral therapy-based prevention and treatment approaches, condom use remains a core component of mitigating these risks. A cross-sectional study characterizing the vulnerabilities for HIV among MSM in Swaziland was analyzed to describe factors associated with condom use at last sex with a male partner.
