Approximating nonlinear differential equations using a neural network provides a robust and efficient tool for various scientific computing tasks, including real-time predictions, inverse problems, optimal controls, and surrogate modeling. Previous works have focused on embedding dynamical systems into networks through two approaches: learning a single operator (i.e.

Background: Despite its prevalence and associated morbidity, we remain limited in our ability to predict the course of a patient with diverticular disease. Although several clinical and genetic risk factors have been identified, we do not know how these factors relate to one another.

Objective: Our aim was to determine whether a polygenic risk score could improve risk prediction for diverticulitis and recurrent diverticulitis compared with a model using only clinical factors.

Multiple gastrointestinal stromal tumors (GISTs) of the small intestine is an uncommon finding but can be a marker for underlying neurofibromatosis type 1 (NF1). We present the case of the 38-year-old male without prior NF1 diagnosis who presented with a small bowel obstruction. His physical exam was notable for cutaneous nodules and café-au-lait spots.

Article Synopsis
  • Acute kidney injury (AKI) is a serious complication after open ventral hernia surgery, and the study aimed to determine if muscle injury from transversus abdominis release (TAR) increases AKI incidence.
  • A retrospective study involving 523 patients found that those who underwent TAR experienced higher blood loss, fluid balance, and longer operation times compared to the non-TAR group.
  • The rate of AKI was higher in the TAR group at 11% versus 6% in the non-TAR group, and TAR was identified as the only factor significantly associated with increased odds of developing AKI.
