Trends in Retraction of Orthopaedic Research Articles.

Background: Despite the use of in-depth peer-review processes, there occasionally are issues with published manuscripts that require retraction. The purpose of the present study was to explore the reasons for the retraction of orthopaedic research articles, with consideration of the journal impact factor and the orthopaedic subspecialty.

Methods: In 2023, a database search was conducted for retracted papers written in the English language in the orthopaedic literature.

"Do No Harm?" Moral Distress Among Medical Students During the Surgical Clerkship.

Objectives: Moral distress, reported among healthcare workers across a variety of settings, is associated with negative mental health consequences, burnout, and intention to leave a position. The scant literature exploring medical students' moral distress does not specifically examine moral distress during the surgical clerkship nor does it characterize the type of moral distress experienced by medical students. Thus, we aimed to explore and characterize medical students' moral distress during the surgical clerkship.

Fertile Hybrids Could Aid Coral Adaptation.

Fertile hybrids can enhance the adaptive capacity and resilience of species under stress by increasing genetic diversity within populations, masking the effects of deleterious recessive alleles, and facilitating the introgression of beneficial genetic variants into parental species. However, many hybrids are infertile. We compared the fertility of aquarium-reared F1 hybrid and purebred corals of the species and and examined the viability of early life stages of second-generation (F2) hybrid and back-crossed planula larvae and recruits.

Coral recruits demonstrate thermal resilience.

Marine heatwaves are becoming more frequent during summer and pose a significant threat to coral reef ecosystems. Restoration efforts have the potential to support native coral populations and guard them against some degree of environmental change, while global action against climate change takes place. Interspecific hybridization is one approach through which resilient coral stock could be generated for restoration.
