Introduction: The prevalence of metabolic dysfunction-associated fatty liver disease (MAFLD) with renal insufficiency in recent years and the association between MAFLD and renal insufficiency are not entirely clear, especially in overweight/obesity. The aim of this study was to analyze the prevalence and risk factors of MAFLD with renal insufficiency in overweight/obese adults.

Methods: Individuals who attended checkup at the Second Affiliated Hospital of Xi'an Jiaotong University from 2016 to 2021 were included. The prevalence of MAFLD with renal insufficiency (estimated glomerular filtration rate ≤90 mL/min/1.73 m2) in overweight/obesity was estimated. Propensity score-matched analysis, univariate and multivariate analyses were used to determine the risk factors for MAFLD with renal insufficiency.

Results: From 2016 to 2021, the prevalence of MAFLD in overweight/obesity reached its highest of 44.7% in 2017 and its lowest of 36.9% in 2018; and 33.9% in 2021 and 21.8% in 2019 is the highest and lowest prevalence of MAFLD with renal insufficiency, respectively. MAFLD was more common in men, old individuals, and persons with a higher body mass index (BMI) and was characterized by significant renal insufficiency. MAFLD with renal insufficiency was more common in women, old individuals, and persons with a higher BMI and was characterized by significant metabolic dysfunction and liver fibrosis. Multivariable analysis showed that BMI, uric acid, and fibrosis (evaluated with noninvasive liver fibrosis score [fibrosis-4]) were independent risk factors for MAFLD with renal insufficiency.

Conclusion: The prevalence of MAFLD with renal insufficiency in overweight/obese adults is quite high in the last 5 years. BMI, uric acid, and fibrosis are independent risk factors for MAFLD with renal insufficiency.

Background: Vascular calcification is common and progressive in patients with chronic kidney disease. However, the risk factors associated with the progression of vascular calcification in patients receiving maintenance dialysis have not been fully elucidated. Here, we aimed to evaluate vascular calcification and identify the factors associated with its progression in patients receiving maintenance hemodialysis.

Objective: This study aimed to explore the perspectives of healthcare professionals on the utility of sick day management plans for people with chronic kidney disease (CKD) in remote communities and collaboratively design a sick day management plan resource.

Design: This qualitative study utilised two phases of data collection: preliminary observational data and semi-structured interviews. The research design and analysis were guided by the normalisation process theory (NPT) framework, tailored for complex interventions in healthcare.

Background: Clinical determination of patients at high risk of poor surgical outcomes is complex and may be supported by clinical tools to summarize the patient's own personalized electronic health record (EHR) history and vitals data through predictive risk models. Since prior models were not readily available for EHR-integration, our objective was to develop and validate a risk stratification tool, named the Assessment of Geriatric Emergency Surgery (AGES) score, predicting risk of 30-day major postoperative complications in geriatric patients under consideration for urgent and emergency surgery using pre-surgical existing electronic health record (EHR) data.

Methods: Patients 65-years and older undergoing urgent or emergency non-cardiac surgery within 21 hospitals 2017-2021 were used to develop the model (randomly split: 80% training, 20% test).

Rescue RM/CS-AKI by blocking strategy with one-dose anti-myoglobin RabMAb.

Rhabdomyolysis or Crush syndrome-related AKI (RM/CS-AKI) has high mortality, and there is no effective early on-site treatment method. The critical pathogenic factor of RM/CS-AKI is the excessive free myoglobin (Mb) in blood circulation. Here, based on the concept of creating a "mobile barrier", we develop an anti-Mb rabbit monoclonal antibody (RabMAb) with high specificity, affinity, stability, and broad species reactivity.
