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 evaluate the efficacy of a cetyl alcohol-containing moisturizing cream (referred to as the emollient) in improving clinical symptoms and preventing disease relapse during the remission phase of mild to moderate infantile atopic dermatitis (AD).Methods:A single-center, investigator-blinded, randomized controlled clinical trial was conducted from February 2022 to October 2023. Sixty participants aged >28 days to ≤2 years with mild to moderate AD (Investigator′s Global Assessment (IGA) score 2 or 3) and controlled disease (IGA 0 or 1) were enrolled. Participants were randomized 1∶1 to either the experimental group (topical emollient applied twice daily combined with a moisturizing cleanser for daily bathing) or the control group (moisturizing cleanser alone). Assessments at weeks 2, 4, 8, and 12 included AD relapse rates, clinical severity scores (IGA and Eczema Area and Severity Index (EASI)), and adverse events.Results:Fifty-six participants were included in the full analysis set. The median time to relapse was 12.0 (6.0-72.0) days in the experimental group versus 8.5 (3.0-19.0) days in the control group (log-rank test: χ2=3.079, P=0.213). Relapse rates were 80.77% (21/26) in the experimental group and 95.83% (23/24) in the control group ( χ2=2.682, P=0.101). The experimental group showed significantly lower IGA scores at weeks 2 and 12 ( P<0.05) and lower EASI scores at weeks 4 and 12 ( P<0.05). Adverse event rates were 8.0% (2/25) and 7.7% (2/26) in the experimental and control groups, respectively ( χ2=0.002, P>0.05) Conclusion:The combination of the cetyl alcohol- containing moisturizing cream and moisturizing cleanser during AD remission may improve clinical symptoms and modestly delay relapse, with a low incidence of adverse events.

Objective To explore the potential categories of self-regulatory fatigue among maintenance hemodialysis patients and their relationships with self-management. Methods A total of 502 maintenance hemodialysis patients in Lanzhou were surveyed using a general information questionnaire, a Self-Regulatory Fatigue Scale, and a Self-Management Scale for Hemodialysis Patients. Potential profile analysis was conducted on self-regulatory fatigue, and its relationship with self-management was explored. Results Based on their self-regulatory fatigue status, maintenance hemodialysis patients could be categorized into four potential groups: low self-regulatory fatigue group (5.0%), moderate self-regulatory fatigue group (49.2%), high self-regulatory fatigue group (13.9%), and high cognitive regulatory fatiguegroup (31.9%). Gender, education level, and monthly per capita family income were identified as influencing factors for the potential categories of self-regulatory fatigue. Significant differences were observed in the total self-management scores among patients belonging to different potential categories of self-regulatory fatigue (F=50.617, P < 0.001). Conclusion Maintenance hemodialysis patients can be classified into four potential categories of self-regulatory fatigue, with patients in the low self-regulatory fatigue group demonstrating higher levels of self-management. Reducing the level of self-regulatory fatigue can contribute to enhancing patients'self-management capabilities.

Central nervous system idiopathic inflammatory demyelinating diseases (CNS-IIDD) is an autoimmune disorder characterized by inflammatory demyelination. The disease follows a course of recurrent attacks and remission, with some cases displaying continuous progression, often resulting in disability. The incidence of CNS-IIDD has been increasing, imposing a substantial burden on both patients′ families and society in recent years. A promising strategy for disease management involves the identification of humoral biomarkers to diagnose CNS-IIDD and predict disease attack and progression. Such biomarkers could aid in identifying individuals at high risk of disability, enabling targeted preventive interventions. This study summarizes advancements in the identification of humoral biomarkers and their potential for predicting disease activity and progression to offer novel insights into the management of CNS-IIDD.

Objective To investigate the changes of serum metabolites in patients with occupational chronic lead poisoning using non-targeted metabolomics, and to screen differential metabolic pathways. Methods A total of 14 patients with occupational chronic lead poisoning were selected as the poisoning group, and 14 healthy people without occupational hazard exposure history were selected as the control group using the judgment sampling method. Serum of the individuals from the two groups was collected. Non-targeted metabolomics technology based on ultra high performance liquid chromatography-tandem mass spectrometry was used to detect serum metabolite levels in the two groups. Differential metabolites (DMs) were screened by the principal component analysis, partial least squares discriminant analysis and orthogonal partial least squares discriminant analysis, and related metabolic pathways were explored. Results The blood lead level in the poisoning group was higher than that in the control group (median: 359.59 vs 5.04 μg/L, P<0.01). There were significant differences in serum metabolites between the poisoning group and control group. After the combination of results from the positive and negative ion patterns, a total of 89 DMs were screened in serum of patients in the poisoning group, including 50 upregulated and 39 downregulated metabolites compared with the control group. The serum DMs of poisoning group were mainly enriched in arginine biosynthesis, ABC transporter, purine metabolism, choline metabolism in malignant tumor, glycerophospholipid metabolism and ether lipid metabolism compared with the control group (all P<0.05). Conclusion Abnormal changes of serum metabolic profile occurred in patients with occupational chronic lead poisoning. The metabolic pathways such as arginine biosynthesis, ABC transporter, purine metabolism, choline metabolism, glycerophospholipid metabolism and ether lipid metabolism may be involved in the occurrence and development of lead poisoning.

With the rising aging population, the number of people with stroke, dementia and Parkinson's disease is huge.These patients often have swallowing dysfunction, cognitive decline, decreased immune function, long-term bed rest, malnutrition, and sarcopenia, and are prone to pneumonia.However, the clinical manifestations of these patients with pneumonia are non-specific.The patients often cannot accurately express their complaints, resulting in symptoms being ignored.The underlying diseases of the nervous system increase the risk of pneumonia-related death, and is associated with poor prognosis.This article aimed to review the risk factors, prevention and treatment of these three neurological disorders complicated with pneumonia.

Community acquired pneumonia(CAP)is characterized by high morbidity and mortality in immunocompromised patients, with the elderly as the main vulnerable population.However, current guidelines in China and elsewhere do not offer specific recommendations on the diagnosis and treatment of such patients.This paper reviews the definition, classification, epidemiology, etiological characteristics, clinical manifestations, diagnosis, treatment and prognosis of CAP in immunocompromised elderly patients, to provide a theoretical framework for its diagnosis and treatment and for the formulation of guidelines.
