Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To assess the clinical and safety outcomes of endovascular therapy(EVT)administered beyond 24 h after the onset of symptoms in patients with acute ischemic stroke(AIS)resulting from middle cerebral artery atherosclerotic occlusion.Methods We enrolled consecutive AIS patients with middle cerebral artery atherosclerotic occlusion who received EVT in our hospital between January 2020 and June 2023 and divided them into two groups based on the time from AIS onset to EVT:EVT≤24 h group and EVT＞24 h group.The National Institutes of Health Stroke Scale(NIHSS)scores after surgery,90-day functional independence(defined as mRS 0-2),symptomatic ICH(sICH),postoperative acute thrombosis,as well as mortality,were analyzed in the two groups of patients.Results A total of 161 patients were recruited,with 106 cases in the EVT≤24 h group and 55 cases in the EVT＞24 h group.The NIHSS scores declined after EVT in both groups(P＜0.01).The NIHSS scores after surgery were lower in the EVT≤24 h group(median:4.5 vs.7.0,P＜0.05).90-day functional independence(45.3％vs.30.9％,95％CI:0.93-3.68),sICH(5.7％vs.9.1％,95％CI:0.18-2.06),postoperative acute thrombosis(6.6％vs.3.6％,95％CI:0.37-9.34),and mortality(3.8％vs.1.8％,95％CI:0.23-19.42)did not differ significantly between the groups(P＞0.05).Conclusion Our findings support EVT feasibility in selected patients with middle cerebral artery atherosclerotic occlusion beyond 24 h.Prospective studies are warranted for confirmation.

Leucine-rich repeat containing protein 15 (LRRC15) gene encodes a type Ⅰ transmembrane protein with 15 leucine-rich repeats(LRRs), which is involved in the occurrence and development of various diseases. Previous studies on LRRC15 gene have mostly focused on its tumor-promoting effects, while the immunoregulatory roles of this gene in non-neoplastic diseases are in the exploratory stage, such as controlling viral infection, participating in changing the functions of osteoblasts and chondrocytes, and promoting the release of pro-inflammatory cytokines, osteogenic differentiation, as well as the proliferation, migration and angiogenesis of fibroblast-like synoviocytes. This paper summarizes the research status and possible roles of LRRC15 gene in non-tumor diseases, hoping to reveal the significant role of this gene in immune regulation.

Objective To analyze the characteristics and risk factors of healthcare-associated infection(HAI)in patients receiving veno-venous extracorporeal membrane oxygenation(V-V ECMO)treatment.Methods Clinical data of 141 patients who received V-V ECMO treatment in the intensive care unit(ICU)of a tertiary first-class hos-pital in Qingdao from January 2019 to November 2023 were collected.Patients were divided into the infection group and non-infection group based on whether HAI occurred.Characteristics of HAI were analyzed,risk factors were analyzed by univariate and multivariate logistic regression analyses.Results Among 141 V-V ECMO patients,inci-dence of HAI was 37.59％(n=53).A total of 81 strains of pathogens were isolated from patients in the infection group,Gram-negative bacteria accounted for 56.79％(n=46),mainly Acinetobacter baumannii,which was up to 28.39％(carbapenem-resistant Acinetobacter baurnannii[CRAB]accounted for 16.05％).The main type of HAI in V-V ECMO patients was pulmonary infection alone(54.72％),followed by bloodstream infection alone(20.75％),multi-site infection accounted for 22.64％.Univariate analysis result showed that compared with the non-infection group,there were statistically significant differences in the history of immunosuppressive agents use,ICU transfer history,surgical history,fiberbronchoscopy,renal replacement therapy,duration of ICU stay,duration of tracheal intubation and/or tracheotomy,duration of urinary catheterization,duration of gastric tube placement,duration of central venous catheterization,duration of antimicrobial use,and duration of V-V ECMO support(all P＜0.05).Multivariate logistic regression analysis result showed that ICU transfer history and fiberbronchoscopy were inde-pendent risk factors for HAI in V-V ECMO patients(OR=6.850,4.643,respectively,both P＜0.05).Conclusion Hospitals should take effective prevention and control measures based on the characteristics and related risk factors of HAI in patients receiving V-V ECMO treatment to reduce the occurrence of HAI.
