Sarcopenia, characterized by reduced muscle mass, decreased strength, and impaired function, can lead to adverse outcomes, such as frailty, falls, fractures and disability, and subsequently lead to decreased quality of life, increased risk of complications and mortality and elevated healthcare costs. With the accelerating process of global aging, the prevalence of sarcopenia has significantly risen, posing a major public health threat and socioeconomic burden to populations worldwide. To more effectively implement medical nutrition management and exercise intervention for patients with sarcopenia, the Chinese Clinical Nutritionist Center of Chinese Medical Doctor Association and the Nutrition Oncology Branch and Geriatric Nutrition Branch of the Chinese Nutrition Society, in collaboration with the Nutrition and Food Safety Branch of Chinese Geriatrics Society, have developed the Expert Consensus on Medical Nutrition Management and Exercise Intervention for Sarcopenia (2024) based on the latest research evidence, clinical practice experiences and clinical nutrition guidelines. This consensus serves as a reference for clinical diagnosis and treatment of sarcopenia. The consensus emphasizes that the diagnosis and treatment of sarcopenia should focus on elderly population and also encompass patients with related chronic diseases including diabetes, inflammatory bowel disease, cancer, cognitive dysfunction and Parkinson's disease. Multi-modal lifestyle interventions centered on nutrition and exercise remain the preferred strategy for the prevention and treatment of sarcopenia.

Gestational diabetes mellitus (GDM) is one of the most common complications of pregnancy, which affects maternal and infantile glucose metabolism both during pregnancy and in the long-term postpartum and is closely related to several perinatal complications. In recent years, many studies devote to exploring early predictive biomarkers of GDM, and a variety of early prediction models of GDM have been established using clinical indicators, biochemical markers, metabolic/proteomic markers, gene polymorphisms, etc. This review summaries and evaluates the published GDM prediction models in terms of research types, modeling methods, indicators, model prediction performance, and validation, attempting to inform the early prevention of GDM.

Diabetes mellitus is a common metabolic disease with serious complications. As people's lifestyle changes, the incidence of diabetes mellitus has gradually increased, and diabetes mellitus has become a global public health issue. Recent studies have found a correlation between blood sugar and eosinophils. Eosinophils may affect the differentiation direction of bone marrow-derived macrophages by promoting the development of beige fat, controlling local inflammation, regulating cell energy metabolism, and resisting vasoconstriction, thereby improving glucose tolerance and insulin resistance and lowering blood sugar levels. In addition, eosinophils are also associated with diabetic ketoacidosis to some extent. This review summarizes the relationship between glycolipid metabolism and eosinophils from the perspectives of phenomenon, mechanism, and clinical application, and speculates that it may play an important role in monitoring the course of diabetes mellitus and reversing diabetes mellitus.

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder and its symptoms are subject to the composition of the gut microbiota. However, it is not yet clear how probiotics relieve IBS, and there is no well-acknowledged standards concerning the clinical application of probiotics. This systematic review was conducted on the literature published from January 2020 to December 2023 and included 12 randomized controlled trials on probiotics in the treatment of IBS. Compared with placebo, the probiotic preparations improved the overall efficacy in IBS patients and was also well tolerated, suggesting the potential of probiotics in IBS management. Nevertheless, different probiotic strains, dosages, combinations, and dosing schedules may affect the outcomes. In the future, large-scale, multi-center, long-term follow-up studies are still needed to clarify the effective strains and methods of use and to promote the use of probiotics in the treatment of IBS.

Vitamin-mineral supplements have clear health benefits in specific populations, but the needs for these nutrients vary among different physiological stages: Periconceptional folic acid supplementation reduces the risk of fetal neural tube defects; iron supplementation prevents iron-deficiency anemia; combined use of calcium and vitamin D helps maintain bone density in middle-aged and older adults; and multivitamin-mineral supplementation may delay age-related cognitive decline in elderly adults. For patients with chronic diseases, regular multivitamin-mineral intake may reduce the risk of respiratory infections and may even alleviate symptoms in specific subpopulations. Studies in Linxian have suggested lower mortality from esophageal cancer after multivitamin-mineral supplementation, although β-carotene may increase lung cancer risk among smokers. A combination of vitamin C and E, zinc, and β-carotene may slow the progression of age-related macular degeneration. Due to the synergistic effects among nutrients, combination formulations may be more advantageous. However, the use of fat-soluble vitamins must be lower than the tolerable upper intake levels to avoid accumulation and toxicity. For individuals at high risk of nutrient deficiency, the vitamin and mineral levels should be tested before supplementation, along with regular monitoring to facilitate dose adjustment. Liver and kidney function should be monitored in patients with chronic diseases after starting supplementation. In summary, vitamin and mineral supplements can improve health outcomes in specific populations. However, the use of these nutrients should be evidence-based and individualized, and vitamin-mineral supplements are not substitutes for medications or a balanced diet.

Objective:To assess the influencing factors of glycemic control among type 2 diabetes mellitus (T2DM) patients, in particular the correlations between peripheral blood eosinophils and metabolic indicators such as glucose, lipids, and uric acid (UA) in these patients.Methods:T2DM patients who were regularly followed up in the Intensive Diabetes Mellitus Clinic of Peking Union Medical College Hospital from January 2016 to September 2024 were prospectively selected as the research subjects. The clinical data of these patients at their first visit and at the 3rd, 6th, 9th, and 12th months of follow-up were collected. The potential correlations of peripheral blood eosinophils with blood glucose control, lipid metabolism, UA metabolism, and inflammation as well as their influencing factors were analyzed.Results:A total of 161 T2DM patients were included. The glycated hemoglobin A1c (HbA1c) compliance rate was significantly higher during the follow-up visits (3, 6, 9, and 12 months) than baseline (all P<0.05) but showed no significant correlation with the count or percentage of peripheral blood eosinophils. Spearman correlation analysis showed that the percentage of peripheral blood eosinophils was negatively correlated with Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) ( P=0.049) and high-density lipoprotein cholesterol (HDL-C) ( P=0.002) and positively with serum triglyceride (TG) ( P=0.034) and UA levels ( P<0.001). A further linear regression model analysis of these four variables and the percentage of eosinophils revealed that the percentage of peripheral blood eosinophils was only linearly correlated with serum UA level ( P<0.001). Conclusion:The percentage of peripheral blood eosinophils in T2DM patients is independently correlated with serum UA level, and monitoring serum UA level is important in T2DM management. Early identification and intervention of hyperuricemia can help provide more comprehensive and precise medical interventions for T2DM patients.

Objective:To compare the types and contents of trace elements in compound trace element preparations used in parenteral nutrition in Beijing against the doses recommended by the guidelines, so as to facilitate optimal choice of preparations for different populations in clinical practice.Methods:The available compound trace element preparations were determined according to the drug list from the Medical Insurance Recruitment and Procurement System of Beijing and the recommended doses of trace elements in the guidelines released by Chinese domestic and foreign nutrition societies were collected and compared.Results:The compound trace element preparations used in Beijing comprised 4 varieties and 6 specifications, with the daily cost ranging from 11.32 to 471 Chinese Yuan. There were 3 varieties of trace element preparations for adults, including multi-trace elements injection (Ⅱ), multi-trace elements injection (Ⅲ), and multi-trace elements injection. Among those, multi-trace elements injection (Ⅲ) met the guideline recommendations best and the price was moderate. For pediatric populations, multi-trace elements injections (Ⅰ) satisfied better the trace element requirements for preterm infants and infants from term to 3 months, while multi-trace elements injections (Ⅲ) outperformed in meeting the trace element requirements for 3-to-12-month infants and children. However, there were still some differences in the trace element contents between the two preparations and the guideline recommendations.Conclusion:The currently available varieties and specifications of trace element preparations basically meet the recommendations of evidence-based guidelines, but there is still the need to improve the instructions for and evidence on the pediatric application of certain preparations.

Objective:To assess the effects of probiotic supplementation following bariatric surgery on weight loss outcomes, glycemic and lipid metabolism profiles, and nutritional status.Methods:Searches were conducted across China National Knowledge Infrastructure (CNKI), WanFang, VIP, Web of Science, and PubMed using Chinese or English search words including probiotics, morbid obesity, severe obesity, bariatric surgery, sleeve gastrectomy, Roux-en-Y gastric bypass, SG, and RYGB up to May 31, 2024. Meta-analysis was performed using Review Manager 5.3. Study quality was evaluated using Cochrane risk of bias tool.Results:In the 12 randomized controlled trials (RCTs) containing 663 severely obese patients who underwent bariatric surgery, 329 were in the probiotic group (receiving probiotic supplementation following bariatric surgery) and 334 in the control group (using placebo). Compared with the control group, the probiotic group had significantly lower fasting blood glucose ( WMD=-4.42 mg/dL, 95% CI: -7.71–-1.13, P=0.009) and triglyceride ( WMD=-18.75 mg/dL, 95% CI: -35.83–-1.67, P=0.03) and significantly increased vitamin B 12 ( SMD=0.52, 95% CI: 0.02–1.02, P=0.04). However, the two groups showed no significant differences in body mass index, waist circumference, weight, % excess weight loss, hemoglobin A1c, insulin, homeostasis model assessment of insulin resistance, total cholesterol, low-density lipoprotein, high-density lipoprotein, or vitamin D levels (all P>0.05). Conclusion:Supplementing probiotics after bariatric surgery can improve glucose and lipid metabolism and increase vitamin B 12 absorption, whereas its potential effect on weight loss remains unclear.

Objective:To study the application of Internet+ follow-up model based on nutrition support team (NST) cooperation in enteral nutrition therapy for patients with inflammatory bowel disease (IBD).Methods:From November 2021 to April 2023, 98 IBD patients admitted to the First Affiliated Hospital of Anhui Medical University were prospectively enrolled and were divided into the observation and control groups (49 cases in each group) using a random number table. The observation group received the intervention of Internet+ follow-up based on NST cooperation and the control group was given routine telephone follow-up. The nutritional indicators, IBD quality of life score, and patient satisfaction with care were compared between the two groups before and 3 months after the intervention.Results:After intervention, the serum albumin, hemoglobin, and pre-albumin levels in the observation group were significantly higher than those in the control group (all P<0.05). After intervention, the IBD quality of life scores of patients in the observation group were significantly higher than those in the control group, in the domains including daily activities, bowel function, social function, and emotional ability (all P<0.05). The patient satisfaction with care in the observation group was 93.62% (44/47), which was significantly higher than that (76.60%, 36/47) in the control group ( P<0.05). Conclusion:The Internet+ follow-up model based on NST cooperation favors the enteral nutrition therapy for patients with IBD as it improves the nutritional status, quality of life, and patient satisfaction with care.

The dramatically rising incidence of chronic diseases decreases quality of life, increases complications and all-cause mortality, and raises medical costs. Scientifically sound nutritional therapy is currently the most affordable and safest basic treatment for patients with chronic diseases, as it can help improve nutritional status, clinical outcomes, quality of life, and survival rates for patients with chronic diseases. The Nutrition Oncology Branch of Chinese Nutrition Society has developed the Expert consensus on nutritional therapy for patients with common chronic diseases (2025) based on the latest research evidence, clinical practice, and clinical nutrition guidelines to inform the nutritional diagnosis and treatment of chronic disease.
