Coaching through liminal phases: A qualitative study of graduating medical students' perceptions of the value of coaching experiences over the course of medical school.

Purpose: To explore graduating medical students' insights on the value of coaching experiences during each year of medical school while examining how coaching may support student development at various stages of training.

Methods: We invited all graduating students who participated in the coaching program from first through fourth year to participate in one 90-minute virtual focus group. We conducted a thematic analysis of all the focus group transcripts using inductive open coding to develop themes.

Multiomic Insights into Human Health: Gut Microbiomes of Hunter-Gatherer, Agropastoral, and Western Urban Populations.

Societies with exposure to preindustrial diets exhibit improved markers of health. Our study used a comprehensive multi-omic approach to reveal that the gut microbiome of the Ju/'hoansi hunter-gatherers, one of the most remote KhoeSan groups, exhibit a higher diversity and richness, with an abundance of microbial species lost in the western population. The Ju/'hoansi microbiome showed enhanced global transcription and enrichment of complex carbohydrate metabolic and energy generation pathways.

Kataegis associated mutational processes linked to adverse prostate cancer presentation in African men.

Kataegis, the focal hypermutation of single base substitutions (SBS) in tumour genomes, has received little attention with respect to prostate cancer (PCa) associated molecular and clinical features. Most notably, data is lacking with regards to this tumour evolutionary phenomenon and PCa racial disparities, with African men disproportionately impacted. Here through comparison between African (n = 109) and non-African (n = 79) whole genome sequenced treatment naïve primary tumours, using a single analytical workflow we assessed for shared and unique features of kataegis.

Rare pathogenic structural variants show potential to enhance prostate cancer germline testing for African men.

Prostate cancer (PCa) is highly heritable, with men of African ancestry at greatest risk and associated lethality. Lack of representation in genomic data means germline testing guidelines exclude for African men. Established that structural variations (SVs) are major contributors to human disease and prostate tumourigenesis, their role is under-appreciated in familial and therapeutic testing.
