Laparoscopic cholecystectomy may have a complicated course with severe complications such as bile duct injury. Studies in other countries than the Netherlands report ambivalent results regarding the influence of a residency program on patient safety, efficacy and financial consequences. This study aims to determine whether there is a difference between laparoscopic cholecystectomy performed in a teaching hospital or a non-teaching general hospital in Dutch clinics. A prospective cohort study was performed to examine the safety of laparoscopic cholecystectomies in a teaching hospital with a residency program and a general hospital without surgical residents. All consecutive cholecystectomies in these two hospitals between September 2014 and March 2015 were included. Patient characteristics, operative procedure, level of experience, operation time, per- and postoperative complications, mortality, length of hospital stay, re-admittance and conversions to laparotomy were analyzed. A total of 294 consecutive cholecystectomies were performed in both hospitals. Cholecystectomies performed in the teaching hospital took an average of 25 min longer to complete compared with a non-residency setting. Both the number of conversions and the number of re-admissions were not significantly different between both clinics. The residency program showed smaller peroperative liver lesions along with more postoperative complications, with most complications in patients that required a conversion. Current practice where residents perform supervised cholecystectomies should not be discouraged. We believe that is safe and lead to an acceptable increase in operation time.

Construct validity and responsiveness of clinical upper limb measures and sensor-based arm use within the first year after stroke: a longitudinal cohort study.

Background: Construct validity and responsiveness of upper limb outcome measures are essential to interpret motor recovery poststroke. Evaluating the associations between clinical upper limb measures and sensor-based arm use (AU) fosters a coherent understanding of motor recovery. Defining sensor-based AU metrics for intentional upper limb movements could be crucial in mitigating bias from walking-related activities.

Division of General Internal Medicine, Department of Medicine, The Ottawa Hospital, Ottawa, Canada.
Introduction: Hospital strain has been shown to negatively impact physician wellness, educational experience, and patient care. To address rising service demands, a non-academic hospitalist service was implemented to reduce daily clinical teaching unit (CTU) census by approximately 30%. Secondary aims were to evaluate physician and trainee wellness on CTU as well as assess unintended adverse patient outcomes.

Objective: To compare the sociodemographic and clinical profiles of patients with advanced cancer admitted to a tertiary palliative care unit before and during the COVID-19 pandemic.
Methods: This is an analysis of data from patients receiving care before (10/21/2019 to 03/16/2020) and during (09/23/2020 to 08/26/2021) the COVID-19 pandemic. Sociodemographic and clinical data were evaluated.
Are medical school preclinical tests biased for sex and race? A differential item functioning analysis.

University of Minnesota Medical School, 420 Delaware Street SE, Mayo Building, Minneapolis, MN, 55455, USA.
Background: A common practice in assessment development, fundamental for fairness and consequently the validity of test score interpretations and uses, is to ascertain whether test items function equally across test-taker groups. Accordingly, we conducted differential item functioning (DIF) analysis, a psychometric procedure for detecting potential item bias, for three preclinical medical school foundational courses based on students' sex and race.
Methods: The sample included 520, 519, and 344 medical students for anatomy, histology, and physiology, respectively, collected from 2018 to 2020.
Periapical bone edema volume in 3D MRI is positively correlated with bone architecture changes.
Insights Imaging

Diagnostic and Interventional Radiology, University Hospital of Zurich, University Zurich, Zurich, Switzerland.
Objectives: To compare and correlate bone edema volume detected by 3D-short-tau-inversion-recovery (STIR) sequence to osseous decay detected by a T1-based sequence and conventional panoramic radiography (OPT).
Materials And Methods: Patients with clinical evidence of apical periodontitis were included retrospectively and received OPT as well as MRI of the viscerocranium including a 3D-STIR and a 3D-T1 gradient echo sequence. Bone edema was visualized using the 3D-STIR sequence and periapical hard tissue changes were evaluated using the 3D-T1 sequence.
