Participation in a Prison-Based Training Programme Is Beneficial for Rescue Dogs.

Dogs are often relinquished because of behavioural issues which may be exacerbated in rehoming centres. Prison-based dog training programmes (DTPs) may enhance outcomes for rescue dogs by providing socialisation and training opportunities to improve behaviour, welfare and likelihood of rehoming. We assessed whether dogs benefitted from participation, 1-3 times per week, in a prison-based DTP in which male young offenders learn how to train and care for dogs waiting to be rehomed. Within DTP sessions, there was significant improvement on a range of training tasks (n = 42 dogs). Analyses of videos (n = 17 dogs) in the kennels and a training barn pre- and post-DTP participation showed improvement in some positive behaviours, but no significant change in other behaviours. Subjective ratings by staff of the dogs' behaviour were made (n = 20 dogs). Desirable behaviours (e.g., playful/friendly) increased, and most undesirable behaviours (e.g., frustrated and noisy) decreased. Participation in the DTP did not mitigate all negative behaviours. However, improvements are consistent with enhanced welfare and likelihood of successful rehoming. Prison-based DTPs can be effective in supporting the work of animal rescue organisations to improve outcomes for dogs, while offering people in custody an opportunity to engage in purposeful activity and provide a community service.

Bacterial vaginosis-driven changes in vaginal T cell phenotypes and their implications for HIV susceptibility.

Bacterial vaginosis (BV) is a dysbiosis of the vaginal microbiome that is prevalent in reproductive-age women worldwide. Adverse outcomes associated with BV include an increased risk of sexually acquired Human Immunodeficiency Virus (HIV), yet the immunological mechanisms underlying this association are not well understood. To investigate BV driven changes to cervicovaginal tract (CVT) and circulating T cell phenotypes, participants with or without BV provided vaginal tract (VT) and ectocervical (CX) tissue biopsies and peripheral blood mononuclear cells (PBMC). Immunofluorescence analysis of genital mucosal tissues revealed a reduced density of CD3+CD4+CCR5+ cells in the VT lamina propria of individuals with compared to those without BV (median 243.8 cells/mm2 BV- vs 106.9 cells/mm2 BV+, p=0.043). High-parameter flow cytometry of VT biopsies revealed an increased frequency in individuals with compared to those without BV of dysfunctional CD39+ conventional CD4+ T cells (Tconv) (median frequency 15% BV- vs 30% BV+, padj=0.0331) and tissue-resident CD69+CD103+ Tconv (median frequency 24% BV- vs 38% BV+, padj=0.0061), previously reported to be implicated in HIV acquisition and replication. Our data suggests that BV elicits diverse and complex VT T cell alterations and expands on potential immunological mechanisms that may promote adverse outcomes including HIV susceptibility.

Preparing Interns as Teachers: Teaching Fourth-Year Medical Students the Tenets of the One-Minute Preceptor Model.

Introduction: Often, interns are expected to teach medical students early in their residency, but most are not formally taught how to be effective teachers before residency. Currently, there is emphasis on developing teaching skills of residents rather than students before they become residents. Most published student-as-teacher courses are voluntary and do not assess skill acquisition. Methods: We taught 290 fourth-year medical students across two academic years (2020-2022) the tenets of the One-Minute Preceptor (OMP) using a 2-hour workshop during their transition to residency course. A variety of role-play cases allowed students to practice the different parts of the OMP in isolation and combined. Then, we assessed their teaching skills after the workshop using an objective structured teaching exam (OSTE). Results: Two hundred seventy-eight students (96%) completed the self-assessment of their confidence demonstrating the skills of the OMP before and after the workshop. Their confidence improved in all domains, with ps < .001. Additionally, all students successfully demonstrated competency on the OSTE. Discussion: We used a 2-hour workshop based on the OMP to improve fourth-year medical students' confidence in their teaching skills and allow them to demonstrate competence in those skills before starting their intern year.
