Examining the Role of Gender and Ethnic Concordance in Medical Student Specialty Selection.

Introduction: Representation of female and minority physicians varies across specialties and may influence career selection by medical students. To investigate the effect of demographic concordance between medical students and clinical role models on specialty selection, we conducted a survey of graduating medical students to assess the perceived importance and influence of third-year clerkship experiences with demographically concordant preceptors on their choice of specialty for post-graduate training. Methods: An 11-question survey was shared nationally through AAMC Organizational Student Representatives to medical students in the Class of 2023. Information gathered included demographics; specialty of choice; extent of exposure to preceptors of the same gender, race, or ethnicity during clinical clerkships; and perceived importance and influence of those interactions (Likert 1-5, Low-High) on specialty selection. Results: A total of 84 students responded. Female students ascribed more importance to gender concordance with preceptors on the third-year clerkship most associated with their specialty of choice than males [3.4 (SD 1.2) vs. 1.3 (SD 0.8) respectively, p < 0.0001] and greater influence to gender concordance on final specialty selection [2.37 (SD 1.1) vs. 1.31 (SD 0.8) respectively, p < 0.0001]. Non-Caucasians ascribed more importance to race/ethnicity concordance than Caucasians [2.8 (SD 1.4) vs. 1.2 (SD 0.5) respectively, p < 0.0001] and greater influence to race/ethnicity concordance on final specialty selection [2.0 (SD 1.3) vs. 1.1 (SD 0.4) respectively, p < 0.0001]. Caucasian females ascribed the greatest importance to gender concordance (p < 0.001), non-Caucasian females ascribed the greatest influence of gender concordance (p < 0.001), and non-Caucasian females ascribed both the greatest importance (p < 0.001) and influence (p < 0.001) to race/ethnicity concordance. Conclusions: We found that gender and race/ethnicity concordance between students and clinical preceptors during third year clerkships is perceived as especially important and influential in specialty selection by minority and female medical students. These findings highlight the importance of diversity in gender and race/ethnicity representation by preceptors on clinical clerkships.

Laparoscopic cholecystectomy: post-operative bile and chyle leaks. A case report.

One week after an elective laparoscopic cholecystectomy at an outside hospital, a 56-year-old male presented to the emergency department with right-sided abdominal pain. Computerized tomography (CT) revealed a complex fluid collection in the gallbladder fossa. The patient underwent drain placement and received broad-spectrum intravenous antibiotics. Drain output was suspicious for a chyle leak, which was confirmed by elevated fluid triglyceride levels. Magnetic resonance cholangiopancreatography (MRCP) and hepatobiliary iminodiacetic acid (HIDA) analysis showed evidence of a concurrent bile leak. After starting a low fat, high protein diet and octreotide, a common bile duct sphincterotomy with plastic stent placement was performed. The patient's symptoms and drain output proceeded to improve. The cause of the chyle leak is unclear. However, with consideration of the patient's concurrent bile leak, an injury to the right major lymphatic drainage pathway and adjacent bile duct is suspected.

Alteration of the cholinergic system and motor deficits in cholinergic neuron-specific Dyt1 knockout mice.

Dystonia is a neurological movement disorder characterized by sustained or intermittent muscle contractions, repetitive movement, and sometimes abnormal postures. DYT1 dystonia is one of the most common genetic dystonias, and most patients carry heterozygous DYT1 ∆GAG mutations causing a loss of a glutamic acid of the protein torsinA. Patients can be treated with anticholinergics, such as trihexyphenidyl, suggesting an abnormal cholinergic state. Early work on the cell-autonomous effects of Dyt1 deletion with ChI-specific Dyt1 conditional knockout mice (Dyt1 Ch1KO) revealed abnormal electrophysiological responses of striatal ChIs to muscarine and quinpirole, motor deficits, and no changes in the number or size of the ChIs. However, the Chat-cre line that was used to derive Dyt1 Ch1KO mice contained a neomycin cassette and was reported to have ectopic cre-mediated recombination. In this study, we generated a Dyt1 Ch2KO mouse line by removing the neomycin cassette in Dyt1 Ch1KO mice. The Dyt1 Ch2KO mice showed abnormal paw clenching behavior, motor coordination and balance deficits, impaired motor learning, reduced striatal choline acetyltransferase protein level, and a reduced number of striatal ChIs. Furthermore, the mutant striatal ChIs had a normal muscarinic inhibitory function, impaired quinpirole-mediated inhibition, and altered current density. Our findings demonstrate a cell-autonomous effect of Dyt1 deletion on the striatal ChIs and a critical role for the striatal ChIs and corticostriatal pathway in the pathogenesis of DYT1 dystonia.
