Objective To investigate the association between lifestyle and risk of heart disease and diabetes in the elderly population in Xi'an City. Methods From January 2021 to January 2024, a staged cluster sampling method was used to investigate the lifestyle and the occurrence of heart disease and diabetes in elderly population aged 60 years and above in the communities of Xi'an. Multivariate logistic regression was used to analyze the relationship between lifestyle and the risk of heart disease and diabetes. Results A total of 413 elderly people were investigated, of which 31.96% had heart disease, 27.12% had diabetes, and 10.90% had diabetes with heart disease. Multivariate logistic regression analysis revealed that age, BMI, family history, sweet food preference, smoking, and sitting and lying for a long time were risk factors for diabetes in the elderly population (P<0.05). Age, BMI, family history, history of diabetes, preference for salted products, smoking, drinking, and sitting and lying for a long time were risk factors for heart disease in the elderly population (P<0.05). Conclusion The incidence rates of heart disease and diabetes are high in the elderly population in Xi'an City. The risk of diabetes is related to unhealthy lifestyles such as sweet food preference, smoking, and sitting and lying for a long time, while heart disease is related to unhealthy lifestyles such as preference for salted products, smoking, drinking, and sitting and lying for a long time.

Foot ulcer prevention plays a crucial role in reducing the amputation rate among diabetic patients. With regard to the prevention of diabetic foot ulcers, the 2023 guidelines of the International Working Group of Diabetic Foot(IWGDF) were different from the 2019 counterpart. The most notable change is the addition of high-level evidence to support recommendations, primarily derived from randomized controlled studies. The 2023 guidelines also advocate for local skin temperature measurement, participation in ankle exercise training, and psychological intervention for foot ulcer prevention. This article conducts a comparative analysis of the two guidelines across six key dimensions: identification of high-risk feet, regular examination of high-risk feet, health education, ensuring appropriate daily footwear, addressing ulcer risk factors, and comprehensive foot care. Drawing from clinical insights, the application and prospective implications of the 2023 guidelines in China are also examined.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To identify the factors associated with the care needs of the older adults aged 65-105 by age groups,and to compare these factors across different age groups.Methods:A total of 12 244 older adults from the Chinese longitudinal healthy longevity survey(CLHLS)conducted in 2018 were included in the analyses.The participants were categorized into three age groups:young-old(aged 65-79),middle-old(aged 80-89),and oldest-old(aged 90-105).The level of disability was measured by the disability index(DI)in four dimensions,reflecting their care needs.Potential factors associated with care needs were selected based on the health ecological model(HEM),including per-spectives of personal characteristics,behavioral characteristics,interpersonal network,living and working conditions,and policy environment.Multifactor analysis was performed using multinomial Logistic regres-sion.Results:Among China's 12 244 older adults,43.4％had medium or high care needs.Factors for higher care needs of older adults included higher age,higher number of chronic diseases,no exercise habit,excessive sleep duration(≥9 h/d),depressive tendency,living with children or spouse,and un-educated(all P＜0.05).In addition,the young-old group who were past smokers(OR=2.009,95％CI:1.019-3.959),were past drinkers(OR=2.213,95％CI:1.141-4.291),and reported self-per-ceived poverty(OR=2.051,95％CI:1.189-3.540),had higher level of care needs.The middle-old group who were female(OR=1.373,95％CI:1.038-1.817),never drank alcohol(OR=1.551,95％CI:1.059-2.269),and were lack of medical insurance(OR=1.598,95％CI:1.053-2.426),and had higher level of care needs.The oldest-old group who were female(medium care needs vs.low care needs:OR=1.412,95％CI:1.062-1.878;high care needs vs.low care needs:OR=1.506,95％CI:1.137-1.993),reported self-perceived poverty(OR=2.064,95％CI:1.282-3.323),and were lack of medical insurance(OR=1.621,95％CI:1.148-2.291),and had higher level of care needs.Conclusion:The identical factors associated with care needs across different age groups include age,chronic disease,exercise,sleep,depression,living arrangement,and education.Smoking,alcohol consumption,and economic status are specific factors among the young-old group of the older adults,while gender and medical insurance are specific factors among the middle-old and the oldest-old group of the older adults.We recommend conducting prospective cohort studies and intervention studies among specific age groups on the above factors to provide reliable evidence for policy formulation.

Background::Copper and zinc are involved in the development of multiple malignancies; yet, epidemiological evidence on hepatocellular carcinoma (HCC) is limited. This study aimed to investigate the association between dietary intake and serum levels of copper and zinc with the risk of HCC.Methods::A total of 434 case-control pairs matched for sex and age (±1 year) were included in this study. Cases with newly diagnosed HCC were from the Guangdong Liver Cancer Cohort (GLCC) study, and healthy controls were from the Guangzhou Nutrition and Health Study (GNHS). A semi-quantitative 79-item food frequency questionnaire (FFQ) was used to assess habitual dietary intakes of copper and zinc. Serum levels of copper and zinc were measured by using inductively coupled plasma mass spectrometry. The copper (Cu)/ zinc (Zn) ratio was computed by dividing copper levels by zinc levels. Conditional logistic regression models were performed to calculate the odds ratio (OR) and 95% confidence intervals (CI) for per 1 standard deviation increase (per-SD increase) in copper and zinc levels.Results::Higher dietary intake (OR per-SD increase = 0.65, 95% CI: 0.44, 0.96, Ptrend = 0.029) and serum levels of zinc (OR per-SD increase = 0.11, 95% CI: 0.04, 0.30, Ptrend <0.001) were both associated with a lower risk of HCC. Subgroup analyses showed that the inverse association was only pronounced in men but not in women ( Pinteraction = 0.041 for dietary zinc intake and 0.010 for serum zinc levels). Serum copper levels (OR per-SD increase = 2.05, 95% CI: 1.39, 3.03, Ptrend = 0.020) and serum Cu/Zn ratio (OR per-SD increase = 6.53, 95% CI: 2.52, 16.92, Ptrend <0.001) were positively associated with HCC risk, while dietary copper intake and dietary Cu/Zn ratio were not associated with HCC risk. Conclusion::Zinc may be a protective factor for HCC, especially among men, but the effects of copper on HCC risk are not clear.

Stenotrophomonas species are non-fermentative Gram-negative bacteria that are widely distributed in environment and are highly resistant to numerous antibiotics. Thus, Stenotrophomonas serves as a reservoir of genes encoding antimicrobial resistance (AMR). The detection rate of Stenotrophomonas is rapidly increasing alongside their strengthening intrinsic ability to tolerate a variety of clinical antibiotics. This review illustrated the current genomics advances of antibiotic resistant Stenotrophomonas, highlighting the importance of precise identification and sequence editing. In addition, AMR diversity and transferability have been assessed by the developed bioinformatics tools. However, the working models of AMR in Stenotrophomonas are cryptic and urgently required to be determined. Comparative genomics is envisioned to facilitate the prevention and control of AMR, as well as to gain insights into bacterial adaptability and drug development.

Comprehensive geriatric assessment clinic can identify geriatric syndrome as well as geriatric health problems, and provide comprehensive systematic diagnosis and treatment for older patients, which is conducive to reducing the number of outpatient visits and saving medical costs.However, the construction of comprehensive geriatric assessment clinic in China is just in the initial stage.There are no guiding opinions on the orientation, work content, work process, and quality management.Therefore, this consensus was conducted based on the latest evidence and expert opinions which aims to provide guidance for the construction of comprehensive geriatric assessment clinic.

Objective: To explore the association between dietary inflammatory index (DII) and metabolic syndrome (MetS) and its components among children aged 6-14 years in Beijing, so as to provide a reference for preventing MetS. Methods: A cross sectional study was carried out in 2 086 records of 1 832 children from the 2017 and 2019 Nutrition and Health Surveillance in Primary and Secondary school students of Beijing (NHSPSB). Three day consecutive 24 hour dietary recalls combined with weighing household cooking oils and condiments were used to collect dietary intake and calculate DII. MetS was diagnosed according to "Definition and Suggestion on the Metabolic Syndrome of Chinese Children and Adolescent". The Generalized estimating equations (GEEs) models were used to analyze the association between DII and the presence of MetS and its components (abdominal obesity, high triglyceride, low high density lipoprotein cholesterol, hypertension, and hyperglycemia). Results: The mean DII score was (1.64±1.07) for the included children. No significant association was found between DII scores and the likelihood of MetS (per 1 point increment: OR =1.16, 95% CI =0.92-1.48, P >0.05). In terms of the components of MetS, DII scores were positively associated with the odds of high triglyceride (per 1 point increment: OR =1.17, 95% CI =1.01-1.36, P <0.05). There was no statistically significant difference in the association among different age groups ( P >0.05). No significant associations were observed between DII and other MetS components( P >0.05). Conclusion DII scores may not be correlated with the risk of MetS, but proinflammatory diet might increase the risk of high triglyceride. DII score in childhood should be emphasized to identify and prevent MetS as soon as possible.
