End-user feedback early in product development is important for optimizing multipurpose prevention technologies for HIV and pregnancy prevention. We evaluated the acceptability of the 90-day dapivirine levonorgestrel ring (DPV-LNG ring) used for 14 days compared to a dapivirine-only ring (DVR-200mg) in MTN-030/IPM 041 (n = 23), and when used for 90 days cyclically or continuously in MTN-044/IPM 053/CCN019 (n = 25). We enrolled healthy, non-pregnant, HIV-negative women aged 18-45 in Pittsburgh, PA and Birmingham, AL (MTN-030 only).

Objective: Obsessive-compulsive disorder (OCD) is associated with altered brain function related to processing of negative emotions. To investigate neural correlates of negative valence in OCD, we pooled fMRI data of 633 individuals with OCD and 453 healthy controls from 16 studies using different negatively-valenced tasks across the ENIGMA-OCD Working-Group.

Methods: Participant data were processed uniformly using HALFpipe, to extract voxelwise participant-level statistical images of one common first-level contrast: negative vs.

Article Synopsis
  • Sleep problems like insomnia are common in autistic adults, affecting around 60% and dramatically reducing their quality of life; tailored treatments like internet-based cognitive behavioral therapy for insomnia (iCBT-I) may offer a solution.
  • * This study will involve 160 autistic adults diagnosed with insomnia to test the effectiveness of a new guided iCBT-I intervention specifically designed for them, called i-Sleep Autism, over a six-week period, comparing results against a waitlist control group.
  • * The trial will measure various outcomes including insomnia severity, mental health, and quality of life at multiple points, helping to determine if this intervention is beneficial for the target population.*

Rates of HIV acquisition remain high among adolescent girls and young women (AGYW) in sub-Saharan Africa. We explored South African, Ugandan, and Zimbabwean AGYW's experiences in a crossover trial of two HIV prevention products: Daily oral pre-exposure prophylaxis pills and a monthly dapivirine vaginal ring. A subset of participants (n = 25) across all sites completed up to three serial in-depth interviews (SIDIs).
