Short-time mentoring - enhancing female medical students' intentions toward surgical careers.

BACKGROUND: Women pursuing a career in surgery or related disciplines are still in the minority, despite the fact that women compose at least half of the medical student population in most Western countries. Thus, recruiting and retaining female surgeons remains an important challenge to meet the need for surgeons and increase the quality of care. The participations were female medical students between their third and fifth academic year. In this study, we applied the well-established psychological theory of planned behavior (TPB) which suggests that the intention to perform a behavior (e.g. pursuing a career in surgery) is the most critical and immediate predictor of performing the behavior. We investigated whether a two-part short-mentoring seminar significantly increases students' intention to pursue a career in a surgical or related specialty after graduation. METHOD: The mentoring and role-model seminar was conducted at 2 days for 90 minutes by six inspiring female role models with a remarkable career in surgical or related disciplines. Participants (N = 57) filled in an online survey before (T0) and after the seminar (T1). A pre-post comparison of central TPB concept attitude towards the behavior, 2) occupational self-efficacy and 3) social norm) was conducted using a paired sampled t-test. A follow-up survey was administered 12 months later (T2). RESULTS: The mentoring seminar positively impacted female students' attitude towards a career in a surgical specialty. Female students reported a significantly increased positive attitude (p < .001) and significantly higher self-efficacy expectations (p < .001) towards a surgical career after participating in the mentoring seminar. Regarding their career intention after the seminar, female students declared a significantly higher intention to pursue a career in a surgical specialty after graduating (p < .001) and this effect seems to be sustainable after 1 year. CONCLUSION: For the first time we could show that short-mentoring and demonstrating role models in a seminar surrounding has a significant impact on female medical student decision´s to pursue a career in a surgery speciality. This concept may be a practical and efficient concept to refine the gender disparity in surgery and related disciplines.

Acute liver injury following acetaminophen administration does not activate atrophic pathways in the mouse diaphragm.

N-acetyl-para-amino phenol (APAP, usually named paracetamol), which is commonly used for its analgesic and antipyretic properties may lead to hepatotoxicity and acute liver damage in case of overdoses. Released cytokines and oxidative stress following acute liver damage may affect other organs' function notably the diaphragm, which is particularly sensitive to oxidative stress and circulating cytokines. We addressed this issue in a mouse model of acute liver injury induced by administration of APAP. C57BL/6J mice (each n = 8) were treated with N-acetyl-para-amino phenol (APAP) to induce acute drug caused liver injury and sacrificed 12 or 24 h afterwards. An untreated group served as controls. Key markers of inflammation, proteolysis, autophagy and oxidative stress were measured in diaphragm samples. In APAP treated animals, liver damage was proven by the enhanced serum levels of alanine aminotransferase and aspartate aminotransferase. In the diaphragm, besides a significant increase in IL 6 and lipid peroxidation, no changes were observed in key markers of the proteolytic, and autophagy signaling pathways, other inflammatory markers and fiber dimensions. The first 24 h of acute liver damage did not impair diaphragm atrophic pathways although it slightly enhanced IL-6 and lipid peroxidation. Whether longer exposure might affect the diaphragm needs to be addressed in future experiments.

Acetaminophen-induced acute liver injury in mice.

The induction of acute hepatic damage by acetaminophen (N-acetyl-p-aminophenol [APAP]), also termed paracetamol, is one of the most commonly used experimental models of acute liver injury in mice. The specific values of this model are the highly reproducible, dose-dependent hepatotoxicity of APAP and its outstanding translational importance, because acetaminophen overdose is one of the most frequent reasons for acute liver failure (ALF) in humans. However, preparation of concentrated APAP working solutions, application routes, fasting period and variability due to sex, genetic background or barrier environment represent important considerations to be taken into account before implementing this model. This standard operating procedure (SOP) provides a detailed protocol for APAP preparation and application in mice, aimed at facilitating comparability between research groups as well as minimizing animal numbers and distress. The mouse model of acetaminophen poisoning therefore helps to unravel the pathogenesis of APAP-induced toxicity or subsequent immune responses in order to explore new therapeutic interventions for improving the prognosis of ALF in patients.
