Objective: To investigate the association between dietary behaviors and overweight and obesity among middle school students, so as to provide the evidence for developing dietary intervention strategies for them. Methods: From October to December 2023, a total of 7 063 middle school students from six counties (districts) in Ma'anshan City, Anhui Province were selected through stratified cluster random sampling method. Demographic information, physical activity, sleep, and dietary behaviors over the past year were collected through questionnaire surveys. Height and weight were measured to calculate body mass index (BMI), with overweight and obesity determined based on gender- and age-specific BMI cut-off points. The association between dietary behaviors and overweight and obesity was analyzed using a multivariable logistic regression model. Results: Totally 7 063 questionnaires were allocated, and 7 045 valid questionnaires were recovered, with an effective recovery rate of 99.75%. There were 3 925 males (55.71%) and 3 120 females (44.29%). A total of 2 326 students were overweight and obesity, with the prevalence of 33.02%. There were significant differences in the prevalence of overweight and obesity among middle school students with different genders, whether they were the only child or not, different intake frequency of sugar-sweetened beverages, and different intake frequency of beans and soy products (all P<0.05). After adjusting for factors such as gender, education stage, whether the only child, whether living on school, physical activity and sleep, multivariable logistic regression analysis showed that the frequency of snack consumption (1-2 times/week, OR=0.803, 95%CI: 0.669-0.963; 3-6 times/week, OR=0.759, 95%CI: 0.623-0.926; daily, OR=0.758, 95%CI: 0.595-0.964), sugar-sweetened beverages consumption (1-2 times/week, OR=1.166, 95%CI: 1.012-1.343; daily, OR=1.891, 95%CI: 1.302-2.746) and beans and soy products consumption (1-2 times/week, OR=0.787, 95%CI: 0.628-0.987) were the influencing factors of overweight and obesity among middle school students. Conclusions The frequencies of snack, beans and soy products and sugar-sweetened beverage consumption are associated with overweight and obesity among middle school students. Targeted interventions should be strengthened to reduce the risk of overweight and obesity.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To compare the functional status of diabetic patients with and without nephropathy and identify the items that diabetic patients with nephropathy are more likely to develop dysfunction than diabetic patients without nephropathy based on the international classification of functioning,disability and health rehabilitation set(ICF-RS).Methods A cross-sectional study was conducted.A total of 320 diabetic patients hospitalized in Guangdong Provincial Hospital of Chinese Medicine from August 2021 to February 2022 were selected and assigned into a group with nephropathy and a group without nephropathy.The general characteristics,clinical examination,and laboratory findings were compared by the t test,rank sum test,and Chi-squared test.The functional status of the patients was compared between the two groups by the t test based on the ICF-RS.Logistic regression was employed to control interferential factors between the two groups and identify the association between nephropathy and ICF-RS problematic items among diabetic patients.Results The diabetic patients with nephropathy had more problematic items in ICF-RS(P<0.001),the body function dimension(P=0.003),the activity dimension(P<0.001),and the participation dimension(P<0.001)than those without nephropathy.Moreover,the diabetic patients with nephropathy experienced severer problems in 5 body function items(energy and drive functions,sleep functions,sexual functions,exercise tolerance functions,and muscle power functions),10 activity items(transferring oneself,walking,moving around using equipment,moving around,washing oneself,caring for body parts,toileting,dressing,doing housework,and looking after one's health),and 4 participation items(using transportation,assisting others,basic interpersonal interactions,and recreation and leisure)(all P<0.05).The Logistic regression results showed that compared with the diabetic patients without nephropathy,the diabetic patients with nephropathy were more likely to develop problems in energy and drive functions(aOR=4.35,95%CI=1.28-14.79,P=0.019),emotional functions(aOR=1.88,95%CI=1.06-3.34,P=0.031),sexual functions(aOR=3.39,95%CI=1.82-6.34,P<0.001),moving around(aOR=3.11,95%CI=1.76-5.52,P<0.001),doing housework(aOR=17.48,95%CI=3.57-85.60,P<0.001),looking after one's health(aOR=1.97,95%CI=1.13-3.43,P=0.017),using transportation(aOR=2.59,95%CI=1.38-4.88,P=0.003),and recreation and leisure(aOR=2.52,95%CI=1.46-4.35,P<0.001).Conclusion Compared with the diabetic patients without nephropathy,the patients with nephropathy suffer more ICF-RS problematic items and are more likely to develop dysfunction in certain items in all the three dimensions.

OBJECTIVES: To study the application value of transport ventilator in the inter-hospital transport of critically ill children. METHODS: The critically ill children in Hunan Children's Hospital who were transported with or without a transport ventilator were included as the observation group (from January 2019 to January 2020; n=122) and the control group (from January 2018 to January 2019; n=120), respectively. The two groups were compared in terms of general data, the changes in heart rate, respiratory rate, and blood oxygen saturation during transport, the incidence rates of adverse events, and outcomes. RESULTS: There were no significant differences between the two groups in sex, age, oxygenation index, pediatric critical illness score, course of disease, primary disease, heart rate, respiratory rate, and transcutaneous oxygen saturation before transport (P>0.05). During transport, there were no significant differences between the two groups in the changes in heart rate, respiratory rate, and transcutaneous oxygen saturation (P>0.05). The incidence rates of tracheal catheter detachment, indwelling needle detachment, and sudden cardiac arrest in the observation group were lower than those in the control group during transport, but the difference was not statistically significant (P>0.05). Compared with the control group, the observation group had significantly shorter duration of mechanical ventilation and length of stay in the pediatric intensive care unit and significantly higher transport success rate and cure/improvement rate (P<0.05). CONCLUSIONS The application of transport ventilator in the inter-hospital transport can improve the success rate of inter-hospital transport and the prognosis in critically ill children, and therefore, it holds promise for clinical application in the inter-hospital transport of critically ill children.

Objective: To evaluate the predictive value of the proportion of hibernating myocardium (HM) in total perfusion defect (TPD) on reverse left ventricle remodeling (RR) after coronary artery bypass graft (CABG) in patients with heart failure with reduced ejection fraction (HFrEF) by ^99mTc-methoxyisobutylisonitrile (MIBI) single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) combined with ¹⁸F-flurodeoxyglucose (FDG) gated myocardial imaging positron emission computed tomography (PET). Methods: Inpatients diagnosed with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2016 to January 2022 were prospectively recruited. MPI combined with ¹⁸F-FDG gated PET was performed before surgery for viability assessment and the patients received follow-up MPI and ¹⁸F-FDG gated PET at different stages (3-12 months) after surgery. Δ indicated changes (post-pre). Left ventricular end-systolic volume (ESV) reduced at least 10% was defined as RR, patients were divided into reverse remodeling (RR+) group and the non-reverse group (RR-). Binary logistic regression analysis was used to identify predictors of RR. Receiver operating characteristic (ROC) curve analysis was performed and the area under the curve (AUC) was calculated to assess the cut-off value for predicting RR. Additionally, we retrospectively enrolled inpatients with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2021 to January 2022 as the validation group, who underwent MPI and ¹⁸F-FDG gated PET before surgery. Echocardiography was performed before CABG and after CABG (3-12 months). In the validation group, the reliability of obtaining the cut-off value for the ROC curve was verified. Results: A total of 28 patients with HFrEF (26 males; age (56.9±8.7) years) were included in the prospective cohort. HM/TPD was significantly higher in the RR+ group than in the RR- group ((51.8%±17.9%) vs. (35.7%±13.9%), P=0.016). Binary logistic regression analysis revealed that HM/TPD was an independent predictor of RR (Odds ratio=1.073, 95% Confidence interval: 1.005-1.145, P=0.035). ROC curve analysis revealed that HM/TPD=38.3% yielded the highest sensitivity, specificity, and accuracy (all 75%) for predicting RR and the AUC was 0.786 (P=0.011). Meanwhile, a total of 100 patients with HFrEF (90 males; age (59.7±9.6) years) were included in the validation group. In the validation group, HM/TPD=38.3% predicted RR in HFrEF patients after CABG with the highest sensitivity, specificity and accuracy (82%, 60% and 73% respectively). Compared with the HFrEF patients in the HM/TPD<38.3% group (n=36), RR and cardiac function improved more significantly in the HM/TPD≥38.3% group (n=64) (all P<0.05). Conclusions: Preoperative HM/TPD ratio is an independent factor for predicting RR in patients with HFrEF after CABG, and HM/TPD≥38.3% can accurately predict RR and the improvement of cardiac function after CABG.

Objective:To understand the status of knowledge, attitude and practice of metabolic syndrome(MS) among the elderly in the community and analyze its influencing factors, so as to provide guidance for the prevention and treatment of MS.Methods:From January 2021 to August 2021, permanent residents(residence duration ≥6 months)aged 65 and above with regular health check examination in Fangzhuang Community Health Service Center of Fengtai District, Beijing were investigated using self-designed MS knowledge, attitude and practice questionnaire.After excluding 34 incomplete questionnaires, the 491 valid questionnaires were recycled with questionnaire valid percentage of 93.5%(491/525). The survey results were analyzed by descriptive analysis, Mann-Whitney U test, Kruskal-Wallis H test and multiple linear regression analysis and multiple linear regression.Results:The scores of MS knowledge, attitude and practice of the elderly in the community were 7(5, 10), 9(8, 10)and 19(18, 21)respectively.The correct answer rate of the diagnostic criteria of MS components was less than 50%.The score of knowledge about MS in the elderly was positively correlated with the scores of attitudes( r=0.263)and practice( r=0.134)(all P<0.01). The results of univariate and multiple linear regression analysis showed that gender, attending educational lectures and the prevalence of MS were the influencing factors of MS knowledge score(all P<0.05). Leisure time, attending educational lectures, pre-retirement occupation and regular health check examination were the influencing factors for MS attitude score(all P<0.05); attending educational lectures, leisure time, regular health check examination and pre-retirement occupation were the influencing factors for MS practice score(all P<0.05). Conclusions:The elderly in the community have a low level of knowledge about the components and diagnostic criteria of MS, but have a positive attitude and practice towards the prevention and treatment of MS.The level of knowledge, attitude and practice of MS is affected by health education lectures, occupation, regular health check examination and other factors.Health education on the diagnostic criteria and the awareness of disease prevention for the elderly in the community should be strengthened to improve the levels of the knowledge, attitude and practice of MS.

Objective:To observe the effect of oral-facial muscle training applying virtual reality technology (VR) and of action observation therapy on the salivation of children with cerebral palsy (CP).Methods:Sixty CP children with uncontrolled salivation were randomly divided into a control group and an observation group, each of 30. In addition to conventional rehabilitation treatment, the control group received routine tongue muscle training, buccal lip muscle training, ice stimulation, and Masako swallowing training. The observation group received oral-facial muscle training based on action observation therapy in a virtual environment. Both groups were trained 30min per day, 5 times a week for 3 weeks. Before and after the treatment, drooling (DDSS) and swallowing function scores were evaluated. Integrated surface electromyography (iEMG) of the buccinator and orbicularis oris muscles was also performed.Results:After treatment, a significant decrease was observed in the average DDSS and the swallowing function scores of both the control and observation groups, along with a significant increase in the average root mean square values of the buccinator and orbicularis oris iEMGs of both groups. However, the average DDSS score of the observation group was significantly lower than that of the control group, while the average iEMG readings were significantly better.Conclusion:VR-based action observation oral-facial muscle training is a more effective supplement to conventional rehabilitation treatment than conventional oral-facial muscle training in improving the salivation of children with CP.

Objective: To investigate the independent risk factors of cardiorenal syndrome type 1 (CRS1) in patients with acute myocardial infarction (AMI) and to build a predictive equation for the development of CRS1 in these patients. Method: Consecutive inpatients with AMI, who hospitalized from January 2017 to December 2018 in the Hunan Provincial People's Hospital, were enrolled in this case-control study. Patients were divided into CRS1 group and non-CRS1 group according to the presence or absence of CRS1.The clinical data were collected through the electronic medical record system of Hunan Provincial People's Hospital. The matching process was conducted with a minimum-distance scoring method and a 1∶1 match between the CRS1 group and the no-CRS1 group, the propensity score was calculated through the logistic regression model. Factors with statistically significant differences in univariate analysis were included in the multivariate logistic regression model to analyze the risk factors of AMI patients with CRS1, then the independent risk factors were used to establish a predicting equation for CRS1 by logistic regression function for model building. Area under the curve (AUC) value and the best cut-off value of the combined predictors was determined according to the ROC curve. Python 3.8 software was used to perform 10-fold cross-validation on modeling samples. Results: A total of 942 patients were included, there were 113 cases in CRS1 group and 829 cases in non-CRS1 group. Ultimately, 99 CRS1 patients were successfully matched to 99 non-CRS1 patient using 1∶1 matching. After propensity score matching, the baseline age and sex along with heart rate, mean arterial pressure, percentage of people with a history of diabetes, hypertension, ST-segment elevation myocardial infarction, myocardial ischemia time, angiotensin converting enzyme inhibitors or angiotensin Ⅱ receptor blockers use, and β receptor blocker use were similar between the two groups(all P>0.05). The contrast agent dosage was also similar between the two groups (P=0.266). The peak cardiac troponin I (cTnI), N-terminal pro-brain natriuretic peptide(NT-proBNP), white blood cell count, base estimated glomerular filtration rate (eGFR), albumin and hemoglobin levels were statistically significant between the two groups (all P<0.05). Multivariate logistic regression analysis showed that decreased baseline eGFR, increased NT-proBNP, peak cTnI concentrations and white blood cell count were independent risk factors of CRS1 in AMI patients (all P<0.01).The predicting equation of the combined predictor was established by transforming the logistic model equation, L=0.031×cTnI+0.000 2×NT-proBNP-0.024×eGFR+0.254×white blood cell count, where L represented the combined predictor. ROC curve analysis indicated that the AUC of the peak cTnI, NT-proBNP, baseline eGFR, white blood cell count, and combined predictor were 0.76, 0.85, 0.79, 0.81, and 0.92 respectively (all P<0.05), and the cutoff value of combined predictor was 2.6. The AUC of ROC curve after the model's ten-fold cross validation was 0.89. Conclusions: Decreased baseline eGFR, increased NT-proBNP, peak cTnI concentrations and white blood cell count are the independent risk factors for CRS1 in AMI patients. The combined predictor equation based on the above 4 biomarkers presents a good predictive value for CRS1 in AMI patients.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

OBJECTIVE: To study the clinical features and recurrence factors of myelin oligodendrocyte glycoprotein (MOG) antibody disease in children and the effect of recurrence prevention regimens. METHODS: A retrospective analysis was performed on the medical data of 41 children with MOG antibody disease who were hospitalized in the Department of Pediatric Neurology, Xiangya Hospital of Central South University, from December 2014 to September 2020. According to the presence or absence of recurrence, they were divided into a monophasic course group ( RESULTS: For these 41 children, acute disseminated encephalomyelitis was the most common initial manifestation and was observed in 23 children (56%). Of the 41 children, 22 (54%) experienced recurrence, with 57 recurrence events in total, among which optic neuritis was the most common event (17/57, 30%). The proportion of children in the recurrence group who were treated with corticosteroids for less than 3 months in the acute phase was higher than that in the monophasic course group (64% CONCLUSIONS More than half of the children with MOG antibody disease may experience recurrence. Most children with recurrence are treated with corticosteroids for less than 3 months in the acute phase. Rituximab and azathioprine may reduce the risk of recurrence.
