Background Under the background of global warming, research on association between ambient temperature and risk of injury is needed. Objective To examine the effect of temperature on injury in Bao'an district, Shenzhen and identify the sensitive population, thereby providing a scientific basis for formulating prevention and control strategies and measures of injury. Methods The injury reports from the Injury Surveillance System and the meteorological data of Bao'an District between 2018 to 2022 were collected. The meteorological data were sourced from the fifth generation of the European Centre for Medium-Range Weather Forecasts (ECMWF) land reanalysis data. Based on time-stratified case-crossover design, conditional logistic regression combined with distributed lag nonlinear model was used to evaluate the exposure-response association between ambient temperature and injury. The stratified analyses were further conducted by gender, age, and causes of injury. Results A total of 156205 injury cases were collected from the injury surveillance sentinel hospitals in Bao'an District of Shenzhen from 2018 to 2022, and the median of daily average temperature during the same period was 20.0 ℃. The exposure-response curve showed that the risk of injury was positively correlated with temperature. The linearized analysis revealed that each 1°C increase in temperature was associated with a 1.05% (95%CI: 0.68%, 1.42%) rise in injury risk (ER). Notably, the effect was greater in females (ER=1.31%, 95%CI: 0.67%, 1.94%) than males (ER=0.92%, 95%CI: 0.47%, 1.37%). Among age groups, adults ＞60 years faced the highest risk (ER=1.91%, 95%CI: −0.36%, 4.24%). The top three temperature-associated injury risks were sharp instrument injuries (ER=2.19%, 95%CI: 1.16%, 3.22%), animal injuries (ER=1.71%, 95%CI: 0.86%, 2.56%), and blunt injuries (ER=071%, 95%CI: −0.08%, 1.51%). The impact of temperature on unintentional injuries (ER=1.11%, 95%CI: 0.72%, 1.49%) was higher than that on intentional injuries (ER=0.43%, 95%CI: −0.85%, 1.72%). Severe injuries (ER=2.20%, 95%CI: −3.09%, 7.77%) were more affected by temperature than mild injuries (ER=1.00%, 95%CI: 0.58%, 1.43%) and moderate injuries (ER=1.15%, 95%CI: 0.42%, 1.89%). Conclusion The increase in ambient temperature associates with injury occurrence, and the impact of temperature exhibits obvious heterogeneity among different populations, indicating that targeted intervention measures should be taken for different populations and types of injuries.

Dementia in traditional Chinese medicine （TCM） mainly presents amnesia and dullness. Alzheimer's disease and vascular dementia belong to the category of dementia in TCM. These progressive neurological diseases have a complex etiology and a long course， and the drugs that can reverse the disease course remain to be developed. Therefore， early intervention plays a vital role in delaying the disease progression. Apathy refers to a lack of motivation that leads to the attenuation or disappearance of goal-directed behaviors， cognitive functions， and emotional responses. Clinical studies have suggested that apathy exists in the early stage of a variety of neurodegenerative diseases， being one of the key symptoms to the early diagnosis of dementia. The severity of apathy is related to the severity of dementia. Therefore， early diagnosis and treatment of apathy are of great significance to the prevention and treatment of dementia. The preclinical research on apathy in dementia is still in its infancy， and the systematic evaluation method has not been prescribed. The clinical diagnosis and treatment are also in the exploratory stage， and the complex pathophysiological mechanisms of apathy and dementia development have not been fully elucidated. This article reviews the research progress of apathy in dementia， the apathetic behaviors of dementia animal models， the behaviors of patients with apathy， and the treatment methods in recent years and summarizes the research status of apathy in dementia. This review aims to provide a theoretical basis for exploring the behavior of apathy in dementia and conducting preclinical research and evaluation of the pathogenesis and to lay a foundation for the treatment of apathy in dementia.

Objective:To analyze the individual and cumulative effects of unhealthy lifestyle on the prevalence of hypertension, diabetes and dyslipidemia in old adults in China, and find out the critical lifestyle in the network.Methods:Based on the baseline data of Yunnan Behavior and Disease Surveillance Cohort in 2021, a total of 16 763 older adults aged ≥60 years were included in our study. The unhealthy lifestyle factors including smoking, drinking, unhealthy eating habit, lower physical activity level, abnormal BMI and abnormal waist circumference. We calculated the unhealthy lifestyle score by using the cumulative exposures of each participant. Multiple logistic regression and mixed graphical models were used to describe the association between unhealthy lifestyle and the prevalence of hypertension, diabetes and dyslipidemia.Results:The prevalence of hypertension, diabetes and dyslipidemia were 57.0%, 11.5% and 37.0%, respectively. Most of the unhealthy lifestyles included in the study were risk factors for hypertension, diabetes and dyslipidemia, and the risks of disease increased with the increase of the unhealthy lifestyle score. The participants with the highest score (score: 6) had significantly higher prevalence of hypertension ( OR=3.99, 95% CI: 1.81-8.80), diabetes ( OR=4.64, 95% CI: 1.64-13.15) and dyslipidemia ( OR=4.26, 95% CI: 2.08-8.73) compared with those with lowest score (score: 0). In the network constructed by mixed graphical model, abnormal waist circumference (bridge strength=0.81) and hypertension (bridge strength=0.55) were vital bridge nodes connecting unhealthy lifestyle and hypertension, diabetes and dyslipidemia. Conclusions:The unhealthy lifestyle score was associated with risks for hypertension, diabetes and dyslipidemia. Abnormal waist circumference was the key factor for chronic diseases in old adults.

Objective To investigate the risk warning indicators for postoperative admission to the intensive care unit(ICU)in patients with ureteral calculi combined with urinary sepsis.Methods The clinical data of 288 patients with ureteral calculi combined with sepsis diagnosed and treated in the First Hospital of Fujian Medical University from October 2020 to October 2023 were retrospectively analyzed,including gender,age,length of hospitalization,clinical conditions[body mass index(BMI),diabetes,hypertension,systemic inflammatory response syndrome(SIRS)score,sequential organ failure assessment(SOFA),quick SOFA(qSOFA)],general indicators[white blood cell count(WBC),body temperature,respiratory rate,heart rate],and degree of hydronephrosis.The patients were divided into two groups:those admitted to the ICU and those not admitted to the ICU after the operation.The differences in the above clinical data between the two groups of patients were compared.Univariate and multivariate Logistic regression analyses were used to screen out the risk factors affecting the admission of patients with ureteral calculi combined with sepsis to the ICU,and the receiver operator characteristic curve(ROC curve)of the subjects was plotted to analyze the predictive efficacy of each risk factor on the admission of patients to the ICU.Results Finally,263 patients were enrolled,out of which 43 patients(16.35％)were admitted to ICU,and all patients recovered and were discharged.Compared with the group not admitted to the ICU,the length of hospitalization in the group admitted to the ICU was significantly longer(days:8.42±1.50 vs.5.51±1.19),and the proportion of patients with diabetes mellitus,the SIRS score,the SOFA score,the qSOFA score,the proportion of patients with body temperatures>39.4℃ or<35.8℃,respiratory rate>20 beats/min,heart rate>90 bpm,and the proportion of patients with severe hydronephrosis were all significantly higher[diabetes mellitus:44.19％(19/43)vs.27.27％(60/220),SIRS scores:3(2,4)vs.2(1,3),SOFA score:7(5,9)vs.4(3,6),qSOFA score:2(1,3)vs.0(0,1),and body temperature>39.4℃ or<35.8℃:44.19％(19/43)vs.25.91％(57/220),respiratory rate>20 beats/min:37.21％(16/43)vs.21.82％(48/220),heart rate>90 bpm:48.84％(21/43)vs.29.55％(65/220),severe hydronephrosis:72.09％(31/43)vs.17.28％(38/220),all P<0.05].Multivariate Logistic regression analyses showed that SOFA score,qSOFA score,and degree of hydronephrosis were independent risk factors for admission to the ICU,with odds ratios(OR)of 1.486,3.546,and 4.423,respectively,along with 95％confidence intervals(95％CI)of 1.146-1.925,1.949-6.543,and 2.355-8.305,P values were 0.003,<0.001,<0.001.ROC analysis showed that,the AUC of SOFA score was the largest of 0.824,the AUC of qSOFA was similar to that of SOFA(0.802 vs.0.824),and the specificity of hydronephrosis was the highest of 82.7％.The joint diagnosis of qSOFA and the degree of hydronephrosis were combined to establish a joint prediction model.The goodness-of-fit test was performed using the Hosmer-Lemeshow test,revealingχ2=8.942,P=0.257>0.05.This indicated that the predictive model of the joint index was well calibrated,and the ROC curves showed improved diagnostic efficacy of the joint index and were superior to that of the SOFA score(AUC:0.889 vs.0.824,P=0.047).Conclusion The qSOFA and the degree of hydronephrosis were independent risk factors for postoperative ICU admission in patients with ureteral calculi combined with urinary sepsis,and the combined diagnosis of the two may provide a good early warning of the risk of ICU admission in such patients.

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 analyze the clinical characteristics, prognosis and gene mutation in patients with dilated cardiomyopathy (DCM) in Keshan disease area of Sichuan Province, and to explore the risk factors for all-cause death in DCM patients.Methods:In June 2016, 55 DCM patients diagnosed at the local disease prevention and control center through clinical manifestations, electrocardiogram examination, and echocardiography were selected as the survey subjects in Mianning County, Liangshan Yi Autonomous Prefecture, and Renhe District, Panzhihua City, Keshan disease areas of Sichuan Province. Baseline clinical data were analyzed and long-term follow-up was conducted. The follow-up period ended June 15, 2021, with the endpoint of all-cause death. Univariate Cox regression was used to analyze the influencing factors of all-cause death in patients, and Kaplan-Meier (K-M) survival curve was used to analyze the survival time of patients. At the same time, peripheral venous blood was collected from 27 DCM patients. After separating white blood cells, DNA was extracted, and whole exome sequencing was performed to screen potential pathogenic genes.Results:Among the 55 DCM patients, 40 were males and 15 were females. The age was (54.09 ± 12.38) years old. The heart function classification of New York Heart Association (NYHA) was mainly grade Ⅱ and Ⅲ, accounting for 94.55% (52/55). The follow-up time for 55 DCM patients was (7.02 ± 2.96) years, and 17 patients experienced all-cause death, accounting for 30.91% (17/55), including 15 males and 2 females. Compared with the survival group, the death group had a lower incidence of syncope (χ 2 = 6.57, P = 0.010), but higher rates of bilateral lower limb edema (χ 2 = 6.43, P = 0.017), pulmonary congestion (χ 2 = 7.61, P = 0.006), intraventricular conduction block (χ 2 = 6.41, P = 0.011), and angiotensin-converting enzyme inhibitor (ACEI) use (χ 2 = 6.57, P = 0.010), as well as increased left ventricular diameter ( t = 2.36, P = 0.022). Univariate Cox regression analysis showed that bilateral lower limb edema [hazard ratio ( HR) = 4.61, P = 0.042] and intraventricular conduction block ( HR = 3.20, P = 0.019) were risk factors for all-cause death of DCM patients. The results of K-M survival curve analysis showed that patients with bilateral lower limb edema and intraventricular conduction block had higher all-cause death rates (log-rank χ 2 = 5.02, 6.24, P = 0.025, 0.012). Whole exome sequencing results showed that 4 patients were detected to carry pathogenic or suspected pathogenic gene mutations, with a positive rate of 14.81% (4/27), involving three genes: β-myosin heavy chain 7 (MYH7), calreticulin 3 (CALR3), and gelsolin (GSN). Conclusions:The all-cause death rate of DCM patients in the Keshan disease area of Sichuan Province is relatively high. Dead patients are prone to bilateral lower limb edema, pulmonary congestion, and intraventricular conduction block, as well as increased left ventricular diameter. Bilateral lower limb edema and intraventricular conduction block are independent predictive risk factors for all-cause death in DCM patients. MYH7, CALR3 and GSN are involved in the pathogenesis of DCM.

OBJECTIVE: This study aims to estimate the cost-effectiveness of the combined chemotherapy regimen containing Bedaquiline (BR) and the conventional treatment regimen (CR, not containing Bedaquiline) for the treatment of adults with multidrug-resistant tuberculosis (MDR-TB) in China. METHODS: A combination of a decision tree and a Markov model was developed to estimate the cost and effects of MDR patients in BR and CR within ten years. The model parameter data were synthesized from the literature, the national TB surveillance information system, and consultation with experts. The incremental cost-effectiveness ratio (ICER) of BR vs. CR was determined. RESULTS: BR ( vs. CR) had a higher sputum culture conversion rate and cure rate and prevented many premature deaths (decreased by 12.8%), thereby obtaining more quality-adjusted life years (QALYs) (increased by 2.31 years). The per capita cost in BR was as high as 138,000 yuan, roughly double that of CR. The ICER for BR was 33,700 yuan/QALY, which was lower than China's 1× per capita Gross Domestic Product (GDP) in 2020 (72,400 yuan). CONCLUSION BR is shown to be cost effective. When the unit price of Bedaquiline reaches or falls below 57.21 yuan per unit, BR is expected to be the dominant strategy in China over CR.
