Given challenges with adherence to existing HIV prevention products, the development of an extended duration vaginal ring could improve adherence while reducing patient and provider burden. Additionally, women have other interlinked sexual health concerns such as unintended pregnancy. We evaluated acceptability of a 90-day ring to prevent HIV and hypothetical preferences for a dual (HIV and contraceptive) indication. This was a secondary analysis of a Phase 1, two-arm, multi-site, placebo-controlled randomized trial evaluating safety and pharmacokinetics of a 90-day vaginal ring containing tenofovir for HIV prevention (N = 49). We used a mixed methods approach to assess quantitative data on acceptability (n = 49) and used qualitative data from a random subset to explain the quantitative findings (N = 25). The 3-month extended duration tenofovir ring was highly acceptable. Participants perceived the ring to be easy to use, comfortable and reported liking it more over time. About half felt the ring during sex but most of those participants said it bothered them only a little. Concerns about hygiene increased over the study period but were often outweighed by the benefits of an extended duration ring. Interest in a multi-purpose ring was high (77%) and even higher among those who were sexually active and had male partners. The 3-month extended duration tenofovir ring for HIV prevention was highly acceptable among women and interest in an MPT was high.

A comprehensive understanding of the factors influencing the epidemiological dynamics of COVID-19 across the pandemic waves-particularly in terms of disease severity and mortality-is critical for optimizing healthcare services and prioritizing high-risk populations. Here we aim to analyze the factors associated with short-term and prolonged hospitalization for COVID-19 during the first three pandemic waves. We conducted a retrospective observational study using data from individuals reported in the e-SUS-VS system who were hospitalized for COVID-19 in a state in a southeast state of Brazil.

Eye tracking has the potential to be used as a meaningful measure of the consequences of vision impairment (VI), yet a comprehensive test battery is lacking. In this study, we sought to evaluate the feasibility and validity of a test battery of eye movements as a tool to measure visual performance in individuals with VI. A test battery including fixation stability, smooth pursuit, saccades, free viewing, and visual search was administered to 46 athletes with VI and 10 control participants.

Pu-erh raw tea (PRT), a post-fermented tea, is prized for its complex flavor profile and health-promoting properties. While extended storage enhances its sensory attributes, the decade-scale metabolic dynamics underpinning flavor evolution remain unexplored. This study comprehensively characterized non-volatile metabolomic profiles and flavor changes in PRT across a 10-year storage period (2012-2023).

Traffic congestion frequently occurs in the drop-off zones of large integrated passenger hubs, posing significant challenges to the efficient utilization of lane space. This study develops a First-In-First-Out (FIFO) taxi drop-off decision-making model, incorporating both static and dynamic Logit frameworks grounded in panel data analysis. The model accounts for heterogeneity across vehicles, temporal variations, and spatial factors influencing drop-off decisions.

Background: Maternal dietary intervention utilizing complex additives rich in β-carotene has demonstrated the capacity to enhance embryonic intestinal development and influence microbial composition in offspring. Nevertheless, the extended impact of maternal β-carotene inclusion on the intestinal health of post-hatching chicks is still not fully elucidated.
Objective: This research aimed to evaluate the impacts of maternal β-carotene supplementation on the intestinal development and microbial communities in chicks after hatching.
