Resident level is associated with operative time in laparoscopic cholecystectomy.

Background: While previous literature has shown that resident involvement increases operative time, the influence of resident involvement on operative time is generally not considered in current methods of case time predictions or operating room planning. Furthermore, evidence of prolonged case times based on the level of the assisting resident is yet scarce. We hypothesized that operative time would increase with the post-graduate year of assisting residents as they gain more autonomy in the operating room.

Temporal order of atrial fibrillation and acute myocardial infarction and associated prognosis in the Danish Diet, Cancer and Health cohort.

Background: Atrial fibrillation (AF) and acute myocardial infarction (AMI) share risk factors and are bidirectionally associated. Several studies found higher risks of outcomes in individuals with both conditions. Whether the risks of outcomes differ according to temporal order of AF and AMI is unclear.

Multiconfigurational short-range on-top pair-density functional theory.

We present the theory and implementation of a fully variational wave function-density functional theory (DFT) hybrid model, which is applicable to many cases of strong correlation. We denote this model as the multiconfigurational self-consistent on-top pair-density functional theory (MC-srPDFT) model. We have previously shown how the multiconfigurational short-range DFT (MC-srDFT) hybrid model can describe many multiconfigurational cases of any spin symmetry and also state-specific calculations on excited states [Hedegård et al.

Risk factors for the incursion of highly pathogenic avian influenza virus into poultry and other captive bird holdings in Denmark from 2020 to 2023: A case-control study.

Highly pathogenic avian influenza (HPAI) is a major concern in terms of animal and human health. Between October 2020 and September 2023, there were 36 HPAI outbreaks detected in poultry and other captive birds in Denmark. However, it is often not possible to determine the exact route of introduction.

Effects of Betaine and Polydextrose on Intestinal Microbiota and Liver Ergothioneine in a High-Fat Diet-Fed Mouse Model and a Human Colonic Simulation Model.

Background/objectives: Ergothioneine (EGT) is an effective antioxidant that animals cannot produce and has an important anti-inflammatory role in cell protection, which can help lower the risk of various diseases. In this study, we investigated the potential role of gut microbiota in the production of EGT, which was found to increase in the mouse liver after dietary supplementation with betaine (BET) or polydextrose (PDX).

Methods: The effects of BET and PDX on the gut microbiota and tissue EGT content were investigated using a diet-induced obese mouse model and simulated fermentation in the human colon.
