Organ Offer Review Cards: Improving Transparency on the Kidney Transplant Waitlist.

INTRODUCTION: The 2022 National Academy of Sciences, Engineering, and Medicine report on equity in organ transplantation highlighted limited transparency and accountability for organ offer declines and recommended prioritizing patient engagement in decisions regarding organ offers. Yet, there is no guidance on how to incorporate patients in organ offers. We elected to study the experiences of patients on the waitlist and their perception of a novel Organ Offer Review Card (OORC). METHODS: A prototype OORC was created using Donornet refusal codes. Sixty randomly selected kidney waitlist patients at a single center were asked to participate in a web-based survey focusing on current medical decision-making preferences and perceptions of the prototype OORC. RESULTS: Among the 43 patients reached, 17 (39.5%) completed the survey. Most participants (88.2%) expressed it was important to be involved in the decision-making about organ offers, with 100.0% of respondents wanting to know why an organ was declined. Regarding the prototype OORC, 94.1% thought it helped them understand the factors and priorities considered when selecting an organ, and 88.2% said it increased their belief that their team was acting in their best interest. CONCLUSION: An OORC could increase transparency and communication during the waitlist process while enhancing trust in the transplant team.

Shifts in the Skin Bacterial and Fungal Communities of Healthy Children Transitioning through Puberty.

Previous cross-sectional studies have shown that skin microbiomes in adults are distinct from those in children. However, the human skin microbiome in individuals as they sexually mature has not been studied as extensively. We performed a prospective, longitudinal study to investigate the puberty-associated shifts in skin microbiota. A total of 12 healthy children were evaluated every 6-18 months for up to 6 years. Using 16S ribosomal RNA (V1-V3) and internal transcribed spacer 1 amplicon sequencing analyzed with Divisive Amplicon Denoising Algorithm 2, we characterized the bacterial and fungal communities of five different skin and nares sites. We identified significant alterations in the composition of skin microbial communities, transitioning toward a more adult microbiome, during puberty. The microbial shifts were associated with Tanner stages (classification method for the degree of sexual maturation) and showed noticeable sex-specific differences. Over time, female children demonstrated a predominance of Cutibacterium with decreasing diversity. Among fungi, Malassezia predominated at most skin sites in more sexually mature subjects, which was more pronounced in female children. The higher relative abundances of these lipophilic taxa-C. acnes and M. restricta-were strongly associated with serum sex hormone concentrations with known influence on sebaceous gland activity. Taken together, our results support the relationship between sexual maturation, skin physiology, and the skin microbiome.
