Mean arterial pressure at the initiation of continuous renal replacement therapy as a prognostic indicator in patients with acute kidney injury.

Background: Acute kidney injury (AKI) is a common complication in critically ill patients, with approximately 5% requiring continuous renal replacement therapy (CRRT). This study investigated the relationship between mean arterial pressure (MAP) and 28- and 90-day mortality in critically ill AKI patients treated with CRRT.

Methods: This secondary analysis of a bicenter, retrospective, observational study included patients with AKI who were treated with CRRT from January 2009 to September 2016.

Inhibition of ASIC1a reduces ferroptosis in rheumatoid arthritis articular chondrocytes via the p53/NRF2/SLC7A11 pathway.

The activation of acid-sensing ion channel 1a (ASIC1a) in response to extracellular acidification leads to an increase in extracellular calcium influx, thereby exacerbating the degeneration of articular chondrocytes in rheumatoid arthritis (RA). It has been suggested that the inhibition of extracellular calcium influx could potentially impede chondrocyte ferroptosis. The cystine transporter, solute carrier family 7 member 11 (SLC7A11), is recognized as a key regulator of ferroptosis.

It plays a significant role in the prevention, diagnosis, treatment, and ongoing monitoring of neurological disorders, and is a critical platform for clinical education.

Pan-cancer analyses reveal cancer-type-specific autophagy signatures with potential implications for prognosis and therapy response.

Autophagy is a common cellular degradation and recycling process that plays crucial roles in the development, progression, immune regulation, and prognosis of various cancers. However, a systematic assessment of the autophagy-related genes (ATGs) across cancer types is deficient. Here, a transcriptome-based pan-cancer analysis of autophagy with potential implications in prognosis and therapy response was performed.

Health-related quality of life profiles in patients with rheumatoid arthritis: a latent profile analysis.

Background: Rheumatoid arthritis (RA) is a common rheumatic disease that most commonly affects joints and negatively impacts individuals' health-related quality of life (HRQoL). Although some studies have explored HRQoL of RA patients, existing studies treated RA patients as a homogeneous group based on their overall HRQoL and ignore the heterogeneity of patients' HRQoL patterns. This study aimed to identify subgroups of RA patients based on their HRQoL and variables associated with group membership.

Haplotype-Resolved Genotyping and Association Analysis of 1,020 β-Thalassemia Patients by Targeted Long-Read Sequencing.

Despite the well-documented mutation spectra of β-thalassemia, the genetic variants and haplotypes of globin gene clusters modulating its clinical heterogeneity remain incompletely illustrated. Here, a targeted long-read sequencing (T-LRS) is demonstrated to capture 20 genes/loci in 1,020 β-thalassemia patients. This panel permits not only identification of thalassemia mutations at 100% of sensitivity and specificity, but also detection of rare structural variants (SVs) and single nucleotide variants (SNVs) in modifier genes/loci.

A multicentre, prospective cohort study comparing two endoscopic procedures for the treatment of gastric muscularis propria lesions.

To date, no prospective study has been conducted to compare the safety and effectiveness of endoscopic snare resection with an elastic band (ESR-EB) and endoscopic snare resection with a transparent cap (ESR-C) for treating gastric muscularis propria lesions. We aimed to compare the safety and effectiveness of ESR-EB with those of ESR-C for gastric muscularis propria lesions less than 10 mm in diameter. A total of 64 patients were enrolled prospectively from May 2023 to November 2023 at Shenzhen Hospital of Southern Medical University, the First Affiliated Hospital of Shantou University, and the People's Hospital of Zhongshan City.

Association between triglyceride to high-density lipoprotein cholesterol ratio and microalbuminuria in the Chinese population.

The evidence for the association between the triglyceride (TG) to high-density lipoprotein cholesterol (HDL-c) ratio and the risk of developing microalbuminuria is still limited in the Chinese population. Therefore, our research will endeavor to explore the relationship between the two. The cross-sectional survey enrolled 32,877 general population from eight regional centers in China.

Melodinines J Induces Apoptosis in Temozolomide-Resistant Glioma Cells by Disrupting TMX1-Dependent Homeostasis of Endoplasmic Reticulum-Mitochondria-Associated Membrane Contacts.

Glioma is recognized as one of the most lethal and aggressive brain tumors. Although the standard-of-care treatment for glioblastoma (GBM) involves maximal surgical resection and temozolomide (TMZ) chemotherapy, the discovery of novel anti-tumor agents from nature sources is an effective strategy for glioma treatment. In this study, we conducted a screening process to identify the bisindole alkaloid melodinine J (MDJ) from Melodinus tenuicaudatus.

Achieving Photocatalytic Overall Nitrogen Fixation via an Enzymatic Pathway on a Distorted CoP Configuration.

Photocatalytic nitrogen (N) fixation over semiconductors has always suffered from poor conversion efficiency owing to weak N adsorption and the difficulty of N≡N triple bond dissociation. Herein, a Co single-atom catalyst (SAC) model with a C-defect-evoked CoP distorted configuration was fabricated using a selective phosphidation strategy, wherein P-doping and C defects co-regulate the local electronic structure of Co sites. Comprehensive experiments and theoretical calculations revealed that the distorted CoP configuration caused a strong charge redistribution between the Co atoms and adjacent C atoms, minimizing their electronegativity difference.
