The role of community health workers in re-entry of people with HIV and substance use disorder released from jail: a mixed methods evaluation of a pilot study.

Background: Incarcerated individuals face high rates of mental illness, substance use disorders and communicable diseases including HIV, with increased health complications and mortality in the early post-release period. Multiple re-entry interventions linking justice-involved individuals to community resources via peer navigation have emerged, though limited data exist on the mechanics and personal impact of these approaches. This paper quantifies and evaluates a pilot study of a combined Community Health Worker (CHW)-re-entry intervention for individuals released from jail who use substances and have HIV to inform future large-scale applications.

Biocompatibility of mussel-inspired water-soluble tissue adhesives.

Wound closure in surgeries is traditionally achieved using invasive methods such as sutures and staples. Adhesion-based wound closure methods such as tissue adhesives, sealants, and hemostats are slowly replacing these methods due to their ease of application. Although several chemistries have been developed and used commercially for wound closure, there is still a need for better tissue adhesives from the point of view of toxicity, wet-adhesion strength, and long-term bonding.

Polymorphic residues in HLA-B that mediate HIV control distinctly modulate peptide interactions with both TCR and KIR molecules.

Immunogenetic studies have shown that specific HLA-B residues (67, 70, 97, and 156) mediate the impact of HLA class I on HIV infection, but the molecular basis is not well understood. Here we evaluate the function of these residues within the protective HLA-B5701 allele. While mutation of Met67, Ser70, and Leu156 disrupt CD8 T cell recognition, substitution of Val97 had no significant impact.

Large Community Outbreak of Legionnaires Disease Potentially Associated with a Cooling Tower - Napa County, California, 2022.

Legionnaires disease is a serious infection acquired by inhalation of water droplets from human-made building water systems that contain Legionella bacteria. On July 11 and 12, 2022, Napa County Public Health (NCPH) in California received reports of three positive urinary antigen tests for Legionella pneumophila serogroup 1 in the town of Napa. By July 21, six Legionnaires disease cases had been confirmed among Napa County residents, compared with a baseline of one or two cases per year.
