Background: Assisted partner services (APS) is an effective strategy for testing people with undiagnosed HIV, but there is limited information on the relative reach and effectiveness of phone versus in-person contact.

Methods: We analyzed data from 31 facilities in Western Kenya providing APS to female index clients newly HIV diagnosed, their male partners, and female partners of men newly HIV diagnosed. Assisted partner services providers attempted contacting partners using phone first and, if unsuccessful, in-person in the community.

In randomized controlled trials, adjusting for baseline covariates is commonly used to improve the precision of treatment effect estimation. However, covariates often have missing values. Recently, Zhao and Ding studied two simple strategies, the single imputation method and missingness-indicator method (MIM), to handle missing covariates and showed that both methods can provide an efficiency gain compared to not adjusting for covariates.

Childhood-onset type 1 diabetes (T1D) is associated with substantial psychiatric morbidity in later life, but it remains unknown whether these associations are due to common underlying biological mechanisms or the impacts of living with the condition and its treatment. Here, using Czech national register data, we identified children with T1D aged ≤14 years between 1994 and 2007 and estimated the risk of psychiatric disorders up to 24 years later. We found that children diagnosed with T1D had an elevated risk of developing substance use, mood, anxiety and personality disorders, and behavioral syndromes.

  • Product adherence significantly impacts the accurate evaluation of HIV-1 prevention methods like the dapivirine vaginal ring, with varying levels of adherence leading to biased efficacy estimates.* -
  • In the MTN-020/ASPIRE trial, per-protocol analyses indicated a 30.8% efficacy, while those with the highest adherence showed an efficacy of 53.6% when analyzing drug release from the ring.* -
  • Advanced statistical methods, such as principal stratification and marginal structural models, enhance our understanding of HIV-1 prevention effectiveness in clinical trials by adjusting for adherence levels.*

While the shape of cortical oscillations is increasingly recognised to be physiologically and functionally informative, its relevance to the aging motor system has not been established. We therefore examined the shape of alpha and beta band oscillations recorded at rest, as well as during performance of simple and go/no-go reaction time tasks, in 33 young (23.3 ± 2.

Persistent pre-exposure prophylaxis (PrEP) use reduces the risk of HIV infection, yet uptake lags among those with the greatest need. Sexual identity stigma may be a significant barrier to PrEP awareness and use among high-risk communities. The primary aim of this study was to determine whether sexual identity was related to PrEP awareness and use.

Additive friction stir deposition (AFSD) is an emerging solid-state additive manufacturing process with a high deposition rate. Being a non-fusion additive manufacturing (AM) process, it significantly eliminates problems related to melting such as cracking or high residual stresses. Therefore, it is possible to process reactive materials or high-strength alloys with high susceptibility to cracking.

Introduction: Assisted partner services (APS) is an effective strategy for increasing HIV testing, new diagnosis, and linkage to care among sexual partners of people living with HIV (PLWH). APS can be resource intensive as it requires community tracing to locate each partner named and offer them testing. There is limited evidence for the effectiveness of offering HIV self-testing (HIVST) as an option for partner testing within APS.

Stepped wedge trials (SWTs) are a type of cluster randomized trial that involve repeated measures on clusters and design-induced confounding between time and treatment. Although mixed models are commonly used to analyze SWTs, they are susceptible to misspecification particularly for cluster-longitudinal designs such as SWTs. Mixed model estimation leverages both "horizontal" or within-cluster information and "vertical" or between-cluster information.

  • The study assessed an unsupervised COVID-19 testing method where university participants self-swabbed at their convenience compared to traditional supervised testing.
  • Over the academic year from September 2021 to July 2022, unsupervised self-swabs were notably less frequent (26,800) than supervised ones (92,499), with higher error rates in unsupervised tests.
  • Results indicated that younger participants and certain racial/ethnic groups were more likely to choose unsupervised testing, with a drop in errors for unsupervised tests as time progressed—showing increasing feasibility over time.

Introduction: In 2018, the Mozambique Ministry of Health launched guidelines for implementing differentiated service delivery models (DSDMs) to optimize HIV service delivery, improve retention in care, and ultimately reduce HIV-associated mortality. The models were fast-track, 3-month antiretrovirals dispensing, community antiretroviral therapy groups, adherence clubs, family approach and three one-stop shop models: adolescent-friendly health services, maternal and child health, and tuberculosis. We conducted a cost-effectiveness analysis and budget impact analysis to compare these models to conventional services.

Additive manufacturing offers greater flexibility in the design and fabrication of structural components with complex shapes. However, the use of additively manufactured parts for load-bearing structural applications, specifically involving cyclic loading, requires a thorough investigation of material fatigue properties. These properties can be affected by many factors, including residual stresses and crack tip shielding mechanisms, which can be very different from those of conventionally manufactured materials.

Article Synopsis
  • Native ambient mass spectrometry imaging allows researchers to map the locations of folded proteins and their complexes in thin tissue sections, enabling visualization of proteins in their natural environment.
  • A key challenge in identifying proteins using this method is the low abundance of proteins in tissues and the difficulty in targeting specific areas due to irregular distributions, which can lead to long data collection times.
  • This study addresses those challenges by incorporating laser capture microdissection, successfully identifying intact protein assemblies in rat liver tissue and the granular layer of the rat cerebellum.

Background: Among men who have sex with men (MSM) and transgender women (TGW), the dynamics of human papillomavirus (HPV) infections at different anatomical sites are not well understood. Information on HPV concordance between anatomic sites can inform the extent of autoinoculation, and susceptibility of different anatomic areas to HPV infection. We described and assessed correlates of HPV concordance across anal, oral, and genital samples.
