Background: To perform an analysis of intraoperative costs associated with arthroscopic rotator cuff repair (RCR) acellular dermal allograft patch augmentation and interposition.

Methods: This was a matched cohort retrospective cost identification analysis. We identified patients who underwent arthroscopic RCR with acellular dermal allograft patch augmentation or interposition between 2014 and 2023 at a single academic center.

Objective: To compare the cost-effectiveness of a gestational carrier to a uterine transplantation in the treatment of absolute uterine-factor infertility.

Design: We performed a cost-effectiveness analysis using a decision-tree mathematical model comparing a gestational carrier to a uterine transplantation.

Subjects: Published literature was used to derive costs for solid organ transplant, immunosuppression, gestational carrier obtainment, in vitro fertilization, preimplantation genetic testing, and frozen embryo transfer.

Human exposure to mycotoxins is common and often severe in underregulated maize-based food systems.

Within a maize smallholder system in Kongwa District, Tanzania, we performed two food surveys of mycotoxin contamination at local grain mills, documenting high levels of aflatoxins and fumonisins in maize destined for human consumption.
