Comparative efficacy of sequential treatment and open abdomen approaches for corrosive abdominal hemorrhage due to inadequate drainage of duodenal leakage: a cohort study.

Background: Intra-abdominal bleeding resulting from inadequate drainage of duodenal leakage (DL) is typically caused by the corrosiveness of duodenal fluid. Open abdomen (OA) treatment addresses both the drainage and bleeding simultaneously. However, a sequential treatment (ST) approach involving hemostasis through transcatheter arterial embolization (TAE) followed by percutaneous drainage of source control has emerged as an alternative method.

High visceral fat-to-muscle ratio predicated a recurrent fistula after definitive surgery for a small intestinal fistula with diffuse extensive abdominal adhesions: a cohort study.

Background: In patients diagnosed with sarcopenia, the presence of chronic preoperative inflammation, assessed by the ratio of the visceral fat area (VFA) to the total abdominal muscle area index (TAMAI) (VFA/TAMAI), has been found to adversely affect wound healing. An elevated VFA/TAMAI may contribute to a higher incidence of postoperative recurrent fistulas (RFs) following definitive surgery (DS) for small intestinal fistulas accompanied by diffuse extensive abdominal adhesions. The objective of this study was to evaluate the predictive value of VFA/TAMAI for postoperative RFs.

Biomimetic Two-Dimensional Vermiculite Nanofluidic Membranes for Stable Salinity-Gradient Energy Conversion.

Aligned ion transport in the nanofluidic membrane is promising for efficient salinity-gradient energy conversion, while remaining rather challenging due to relatively inadequate mass transport and long-time durability. In this work, wet-chemically exfoliated and negatively charged vermiculite lamellas are readily restacked into free-standing membranes with massive arrays of nanochannels and a three-dimensional interface. The resulting vermiculite nanofluidic membranes possess excellent stability against harsh conditions including a wide pH range and high temperature and exhibit a different ion transport behavior from the macroscopic one due to the surface-charge-governed conductivity.
