Purpose: Early laparoscopic cholecystectomy (ELC) is the treatment of choice for acute cholecystitis (AC), but the optimal surgical timing is controversial. The aim of this study was to retrospectively verify the outcome of patients with AC according to different timing of cholecystectomy.
Methods: Patients undergoing cholecystectomy for AC from 2006 to 2012 were stratified into two groups: initial admission cholecystectomy (IAC) and delayed cholecystectomy (DC, after at least 4 weeks). Among IAC, a subgroup undergoing immediate cholecystectomy (IC, within 72 h of symptom onset) was further analyzed.
Results: Three-hundred and sixteen consecutive patients were studied. IAC group included 262 patients (82.9 %) and DC group included 54 patients (17.1 %). The two groups were similar in conversion rate, operation length, and overall complication rate. The total length of hospitalization was longer in DC patients (p = 0.005). Among DC patients, 25.9 % required re-hospitalization while waiting an elective procedure. In the group undergoing IC (66 patients), conversion rate, length of operation, and postoperative morbidity were similar to that of the IAC group. Length of stay was shorter in IC group (p < 0.001). Multivariate analysis identified moderate-severe AC grading and ASA score ≥ 3 as predictors of postoperative complications.
Conclusions: The timing of cholecystectomy for AC does not seem to affect conversion rate and postoperative morbidity. Therefore the 72-h period should not be considered a strict limit to perform LC, provided that the operation is carried out during the initial hospital admission.

Aramid films are potential separator candidates for high-safety lithium-ion batteries (LIBs) due to their inherent flame retardancy and outstanding thermal stability. However, both weak liquid electrolyte wettability and poor mechanical properties of aramid separators for lithium-ion batteries result in low ionic conductivity and unsatisfactory electrochemical performance for LIBs. Herein, a novel asymmetric porous composite separator composed of a relatively dense nanocellulose (CNC) layer and a porous poly(m-phenylene isophthalamide) (PMIA) supporting layer has been fabricated by using a water-induced phase conversion process.

Background: Minimally invasive liver surgery has rapidly evolved in recent years. In addition to the laparoscopic liver resection (LLR), robot-assisted liver resection (RLR) is increasingly gaining in importance; however, although the robotic-assisted approach offers clinical benefits, particularly in complex procedures, it remains a matter of debate.
Objective: The aim of this study was to present the development, perioperative outcomes, key challenges, and insights from over 500 minimally invasive liver resections performed at a specialized high-volume center.

Post-synthetic modification (PSM) offers a promising approach for tailoring the compositional, structural, and electronic properties of covalent organic frameworks (COFs), thereby enhancing their exciton dissociation ability and facilitating charge transfer. The effectiveness of these approaches is largely compromised by the harsh conditions, complexity, and alteration of the original structure. Therefore, developing a facile yet effective PSM for modulating COFs' properties without altering the original geometry and/or structure is a challenge.

Suppressing photoinduced charge recombination represents a critical challenge in photocatalytic ammonia (NH) decomposition for hydrogen (H) production. Herein, we propose a dual-cocatalyst system comprising plasmonic silver (Ag) and nickel oxide (NiO), which synergistically construct an Ag → titanium dioxide (TiO) → NiO directional electron cascade on TiO surfaces through work-function-induced interfacial charge transfer. The optimized 3 %Ag-1 %NiO-TiO reaches a significantly photocatalytic H production rate of 2366.
