This systematic review and meta-analysis aims to detecting performance of muscular ultrasound for intensive care unit (ICU)-acquired weakness (ICUAW). ⋯ 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.

Chronic kidney disease (CKD)-related vascular calcification (VC) is a common degenerative phenomenon of the vessel wall and its pathological basis is the phenotypic transformation of vascular smooth muscle cell (VSMCs). Zinc finger and BR-C (Broad-Complex), ttk (tramtrack) and bab (bric à brac) (BTB) domain containing 16 (ZBTB16) has been reported to be expressed in the aortic tissues in a rat model of VC. This work is conducted to reveal the functions of ZBTB16 on VC in CKD and to probe its involved reaction mechanisms. ⋯ Moreover, silencing with ZBTB16 inactivated Wingless-related integration site (Wnt)/β-catenin pathway. LiCl (Wnt/β-catenin agonist) reversed the protective effects of ZBTB16 knockdown on the calcification and osteoblastic transformation in vitro. Together, ZBTB16 silencing may down-regulate Wnt/β-catenin pathway to protect against CKD-associated VC via repressing the osteoblastic transformation of VSMCs.

Cardiac arrest (CA) is one of the most severe complications in patients with intracerebral hemorrhage (ICH), increasing the risk of death. This study explored the factors influencing CA occurrence and its resuscitation characteristics in ICH patients. ⋯ PRE-EMS, posthospital hematoma expansion, and swallowing dysfunction were identified as co-factors contributing to CA occurrence and post-CA mortality following ICH. The proportion of CA patients following ICH decreased, while survival rates improved annually from 2015 to 2019.

Acute infections and sepsis are a leading cause of death. These patients are primarily encountered at the emergency department (ED), where early assessment for sepsis is necessary to improve outcome. In sepsis, the inflammatory response causes several characteristic pathophysiological changes, including a dysregulated and generalized activation of the endothelium. This study aimed to analyse endothelial markers released to the blood as diagnostic biomarkers for acute infection and sepsis in the ED, as smaller studies have previously shown promising results in other settings. ⋯ Despite promising results in small studies and specific cohorts, particularly in intensive care units, this large-scale evaluation of four endothelial biomarkers highlights their limited diagnostic utility in a broader inclusion set-up design at the earliest possible time-point of evaluation.

Sepsis progression is marked by a complex immune response, where the involvement of hypoxia-inducible factors (HIF) plays an uncertain role. The study aims to elucidate the involvement of HIF-1α in monocyte function during sepsis and its potential as a prognostic indicator. ⋯ HIF in monocytes acts as a suppressor of immune-inflammatory responses and antigen presentation, and may serve as a negative molecular marker for sepsis development.
