Severe acute pancreatitis (SAP) is a highly morbid acute digestive disorder linked to pyroptosis. N-acetyltransferase 10 (NAT10) facilitates the production of N4-acetylcytidine (ac4C) modifications in mRNA, thereby contributing to the progression of various diseases. However, the specific role of NAT10 in SAP remains to be elucidated. ⋯ Moreover, NAT10 knockdown alleviated pancreatic tissue pathology, mitigated SAP severity, and suppressed pyroptosis in an SAP rat model. Collectively, these results demonstrate that NAT10 exacerbates pancreatic injury in SAP by promoting pyroptosis through ac4C modification of NLRP3, thereby enhancing its expression. These findings suggest a potential novel therapeutic target for SAP.

Meta Analysis
Use of muscular ultrasound to detect intensive care unit-acquired weakness: a systematic review and Meta-analysis.
Background : This systematic review and meta-analysis aims to detecting performance of muscular ultrasound for intensive care unit (ICU)-acquired weakness (ICUAW). Methods : We searched PubMed, Web of Science, Embase, Cochrane library, CNKI, VIP, and Wanfang databases for articles published before July 2024. A random-effects model was utilized to derive the summary estimates of sensitivity, specificity, and diagnostic odds ratio (DOR) with 95% confidence interval (CI). ⋯ Furthermore, integrated analysis of these two indicators revealed that the cross-sectional area of rectus femoris was statistically superior to the thickness of rectus femoris, with higher sensitivity (0.82 [95%CI 0.74-0.87] vs. 0.75 [95%CI 0.65-0.83], P < 0.05) and AUC (0.91 [95%CI 0.88-0.93] vs. 0.80 [95%CI 0.76-0.83], P < 0.01). Conclusions : Muscular ultrasound could be a reliable tool for ICUAW detection. Compared with alternative indices, the cross-sectional area of the rectus femoris exhibits superior detection efficacy and may be considered as a valuable parameter for clinical application.

Background: Acute respiratory distress syndrome (ARDS) is a serious pathological process with high mortality. Ferroptosis is pivotal in sepsis, whose regulatory mechanisms in sepsis-induced ARDS remains unknown. We aimed to determine key ferroptosis-related genes in septic ARDS and investigate therapeutic traditional Chinese medicine. ⋯ Conclusions: Ferroptosis-related genes of IL1B , MAPK 3, and TXN serve as potential diagnostic genes for sepsis-induced ARDS. Sea buckthorn may be therapeutic medication for ARDS. This study provides a new direction for septic ARDS treatment.

In recent years, it has become apparent that fibrinolytic dysfunction and endotheliopathy develop in up to 40% of patients during the first hours following thermal injury and are associated with poor outcomes and increased resuscitation requirements. Rapidly following burn injury, the fibrinolytic system is activated, with activation generally greater with increased severity of injury. Very high plasma concentrations of plasmin-antiplasmin complex (marker of activation) have been associated with mortality. ⋯ Here we review the incidence and effects of these responses after burn injury and explore mechanisms and potential interactions with the early inflammatory response. Available data from burn and nonburn trauma suggest that the fibrinolytic, endothelial, and inflammatory systems interact extensively and that dysregulation in one may exacerbate dysregulation in the others. This raises the possibility that successful treatment of one may favorably impact the others.

Randomized Controlled Trial Multicenter Study
ANGIOTENSIN II FOR CATECHOLAMINE-RESISTANT VASODILATORY SHOCK IN PATIENTS WITH ACUTE KIDNEY INJURY: A POST HOC ANALYSIS OF THE ATHOS-3 TRIAL.
Objective: The combination of catecholamine-resistant vasodilatory shock and acute kidney injury (AKI) is associated with high morbidity and mortality. The role of angiotensin II (ANGII) in this setting is unclear. Methods: We conducted a post hoc analysis of the Angiotensin II for the Treatment of High-Output Shock (ATHOS) 3 trial which assessed the effect of Intravenous ANG II or placebo in patients with refractory vasodilatory shock in 75 intensive care units across nine countries in North America, Australasia, and Europe. ⋯ Additionally, in this subgroup, compared with placebo, patients receiving ANGII were more likely to achieve a MAP response (P < 0.001) and had more days alive and free from RRT (P < 0.001). Conclusions: Compared with placebo, in patients with catecholamine-resistant vasodilatory shock and stage 3 AKI, ANGII is associated with lower 28-day, greater likelihood of MAP response, and more days alive and free from RRT. These findings support the conduct of future ANGII trials in patients with stage 3 AKI.
