The Leaky Preexposure Prophylaxis Cascade: Barriers and Facilitators to Preexposure Prophylaxis Uptake and Adherence Among Youth Experiencing Homelessness in the US South, a Mixed Methods Study.

Adherence to preexposure prophylaxis (PrEP) is lower among high-risk populations, including youth experiencing homelessness (YEH). This study determined the feasibility of urine PrEP adherence biomarker testing and examined the barriers and facilitators to PrEP uptake and adherence among YEH. YEH were recruited from a randomized control trial conducted in a large urban setting in southern United States.

Systemic Antibiotic Prophylaxis Adjunctive to Surgical Reconstructive Peri-Implantitis Treatment: A Retrospective Study.

Aims: To evaluate the clinical efficacy of oral systemic antibiotic prophylaxis administered along with the surgical reconstructive peri-implantitis treatment.

Methods: A total of 49 patients exhibiting 70 implants diagnosed with peri-implantitis underwent a surgical reconstructive peri-implantitis treatment. Of them, 27 patients (38 implants) received a single preoperative shot of antibiotics (2 g amoxicillin; Pre-op), 12 patients (19 implants) were prescribed with postoperative antibiotics for 3 days (500 mg amoxicillin, 3 x day, Post-op), and the remaining 10 patients (13 implants) did not receive any systemic antibiotics (No-Ab).

Results of a Randomized Wait-List Controlled Trial of CAYA: A Nurse Case Management HIV Prevention Intervention for Youth Experiencing Homelessness.

Youth experiencing homelessness (YEH) face challenges that increase their susceptibility to HIV/STIs. Nurse case management is effective in managing the complex needs of populations experiencing homelessness and reducing HIV risk. A randomized wait-list control study conducted between September 2019 to May 2023 evaluated the CAYA "Come As You Are" intervention.

Protein Consumption and Risk of CVD Among U.S. Adults: The Multi-Ethnic Study of Atherosclerosis (MESA).

Background: Although some randomized trials have reported beneficial effects of protein intake on cardiometabolic risk factors, evidence from prospective studies have not supported a strong link between protein intake and cardiovascular disease (CVD) risk. It is also unclear whether diversity in protein intake plays a role in CVD risk.

Objective: We investigated prospective associations of (1) protein intake, overall and by food source and (2) diversity of protein sources with risk of CVD, coronary heart disease (CHD), and stroke.

Dilatational-plasticity opens a new mechanistic pathway for macromolecular transport across glassy interfaces.

Interdiffusion-based macromolecular transport across glassy interfaces is reportedly achieved at high temperatures in accordance with the classical model of reptation. Here, for the first time, we report a new mechanistic pathway for achieving solid-state glassy joining by triggering rapid macromolecular acceleration through mechanical deformation. Large-scale molecular simulations reveal that active plastic deformation in glassy polymers, at temperatures well below the bulk (and surface) glass transition temperatures (and ), causes segmental translations of macromolecules leading to interfacial interpenetrations, and the formation of new entanglements.
