From self-efficacy to imposter syndrome: The intrapersonal traits of surgeons

BACKGROUND: Demographic differences among surgical trainees regarding intrapersonal traits, such as imposter syndrome and assertiveness, have become widely acknowledged. However, many of these characteristics have not been examined in tandem, nor among both trainees and surgeons in practice. This study aimed to address these knowledge gaps. METHODS: This was an anonymous, voluntary survey study comprised of validated measures of (1) self-efficacy, (2) imposter syndrome, (3) assertiveness, (4) perfectionism, and (5) self-rated likeability. A multimodal recruitment strategy was used and surgeons across all subspecialties were eligible for inclusion. RESULTS: A total of 296 participants were included, with 54% identifying as female (n = 161) and 72% between the ages of 25 and 40 years of age (n = 212). Imposter syndrome, assertiveness, and perfectionism scales were normally distributed; self-efficacy and self-rated likeability scales demonstrated slight negative skew. Self-identified male sex was associated with less imposter syndrome (P \u3c 0.001) and perfectionism (P = 0.035) and higher assertiveness (P \u3c 0.001). Imposter syndrome was less common among older age groups (P = 0.001). CONCLUSIONS: Surgeons are a self-efficacious group of perfectionists with widespread variability in imposter syndrome and assertiveness. Female sex and younger age were associated with more imposter syndrome and less assertiveness, highlighting an opportunity for early career coaching

A rare case of anatomical variation of the femoral artery and vein

During a dissection of the two femoral trigons in a female corpse, about 14 years old, we discovered on the right side, the deep artery of the thigh arising from the medial side of the femoral artery and passed in front of the femoral vein above the mouth of the great saphenous vein; on both sides, there was the presence of a collateral canal which communicated the external iliac vein with the femoral vein on the right, on the left, it communicated the external iliac vein with the quadricipital vein. The lower part of the femoral vein was duplicated on both sides, but on the right, there was an interconnecting channel between the two trunks of the duplication. Variations of the femoral vessels are very frequent and can be responsible for an incident during the practice of certain gestures at the level of the femoral trigon such as: catheterization of the femoral artery or vein, the treatment of femoral hernias. Key words: Deep thigh artery, collateral venous canal, external iliac vein, anatomic variations

Schistosoma mansoni infection in a recently exposed community in Senegal: lack of correlation between liver morphology in ultrasound and connective tissue metabolites in serum

Four hundred and seventy villagers of Ndombo, a village with recently established intensive transmission of Schistosoma mansoni in the Senegal River Basin, were enrolled in a study with the intention to assess hepatosplenic morbidity. All patients were examined parasitologically and by ultrasound. Hepatic fibrosis serum markers were determined in 153 adult patients (aminoterminal propeptide of procollagen type III, hyaluronan and laminin). By ultrasound, about 60% of the patients showed early stages of hepatic involvement, 3% of the patients unequivocally showed severe hepatosplenic pathology (grade 3 according to the Managil classification), whereas in another study performed in the same village 3 years earlier, no patients with severe hepatosplenic pathology had been found. No correlation between the aminoterminal propeptide of procollagen type III, hyaluronan or laminin and the ultrasound findings could be established. These hepatic fibrosis serum markers do not seem to be a sensitive method to detect early hepatic fibrosis in schistosomiasis

Seasonal, diurnal and vertical variation of chlorophyll fluorescence on **Phyllostachys humilis** in Ireland

In recent years, temperate bamboo species have been introduced in Europe not only as an ornamental plant, but also as a new biomass crop. To measure adaptation stress of bamboo to the climate of Western Europe, chlorophyll fluorescence was measured on a diurnal and seasonal basis in Ballyboughal, Co. Dublin, Ireland. Measurements were attained on the leaves of each node of Phyllostachys humilis. The most frequently used parameter in chlorophyll fluorescence is the photosynthetic efficiency (Fv/Fm). A seasonal dip - as well as a larger variation - of Fv/Fm in spring compared to the rest of the year was observed. Over the year, the upper leaves of the plant perform better than the bottom leaves. These findings were linked to environmental factors such as light intensity, air temperature and precipitation, as increased light intensities, decreasing air temperatures and their interactions, also with precipitation levels have an effect on the photosynthetic efficiency (Fv/Fm) in these plants
