Objective To analyze the health management situation of non-communicable chronic disease(NCD)in Chongqing City and Guizhou Province and its influencing factors.Methods A stratified random sampling method was used to select 16 representative primary medical and health institutions from Chongqing City and Guizhou Province as the research sites,and the data were collected through the combination method of qualitative and quantitative research.Results A total of 760 patients with NCD were surveyed,and the awareness rate,utilization rate and satisfaction rate of the NCD health management program all exceeded 84.2％,while the awareness rate,utilization rate and satisfaction rate of follow-up and categorical intervention were the lowest.The awareness rate of hypertension physical examination in the patients with＜60 years old was lower than that in the patients with 60-＜70 years old(OR=4.28,95％CI:1.43-12.81)and the pa-tients with ≥70 year sold(OR=3.16,95％CI:1.12-8.91);the utilization rate of diabetes screening in the patients with＜60 years-old was lower than that in the patients with ≥70 years old(OR=2.70,95％CI:1.08-6.76)and the awareness rate of hypertension physical examination was lower than that of the patients with 60-＜70 years old(OR=4.24,95％CI:1.01-17.75);the awareness rate of hypertension physical ex-amination in the patients in Chongqing City was higher than that in Guizhou Province(OR=0.15,95％CI:0.04-0.54)and the utilization situation was better than that in Guizhou Province(OR=0.13,95％CI:0.05-0.34).Conclusion The overall situation of NCD management services in Chongqing City and Guizhou Province is good,but the service quality of follow-up and classified intervention projects needs to be further improved.

Purpose::Traumatic brain injury (TBI), currently a major global public health problem, imposes a significant economic burden on society and families. We aimed to quantify and predict the incidence and severity of TBI by analyzing its incidence, prevalence, and years lived with disability (YLDs). The epidemiological changes in TBI from 1990 to 2019 were described and updated to provide a reference for developing prevention, treatment, and incidence-reducing measures for TBI.Methods::A secondary analysis was performed on the incidence, prevalence, and YLDs of TBI by sex, age group, and region ( n =21,204 countries and territories) between 1990 and 2019 using the Global Burden of Diseases, Injuries, and Risk Factors Study 2019. Proportions in the age-standardized incidence rate due to underlying causes of TBI and proportions of minor and moderate or severe TBI were also reported. Results::In 2019, there were 27.16 million (95% uncertainty intervals ( UI): 23.36 -31.42) new cases of TBI worldwide, with age-standardized incidence and prevalence rates of 346 per 100,000 population (95% UI: 298 -401) and 599 per 100,000 population (95% UI: 573 -627), respectively. From 1990 to 2019, there were no significant trends in global age-standardized incidence (estimated annual percentage changes: -0.11%, 95% UI: -0.18% --0.04%) or prevalence (estimated annual percentage changes: 0.01%, 95% UI: -0.04% -0.06%). TBI caused 7.08 million (95% UI: 5.00 -9.59) YLDs in 2019, with age-standardized rates of 86.5 per 100,000 population (95% UI: 61.1 -117.2). In 2019, the countries with higher incidence rates were mainly distributed in Central Europe, Eastern Europe, and Australia. The 2019 global age-standardized incidence rate was higher in males than in females. The 2019 global incidence of moderate and severe TBI was 182.7 per 100,000 population, accounting for 52.8% of all TBI, with falls and road traffic injuries being the main causes in most regions. Conclusions::The incidence of moderate and severe TBI was slightly higher in 2019, and TBI still accounts for a significant portion of the global injury burden. The likelihood of moderate to severe TBI and the trend of major injury under each injury cause from 1990 to 2019 and the characteristics of injury mechanisms in each age group are presented, providing a basis for further research on injury causes in each age group and the future establishment of corresponding policies and protective measures.

Objective To investigate disease characteristics and hospitalization costs of children with Mycoplasma Pneumoniae pneumonia(MPP)admitted to Shanghai municipal medical hospitals from 2019 to 2023.Methods Depending on the Shanghai Municipal Hospital Pediatric Alliance,we retrospectively investigated community acquired MPP pediatric patients hospitalized in 22 municipal hospitals with pediatric qualifications(including 4 children's hospitals)in Shanghai from Jan 2019 to Dec 2023.We collected the patients'diagnosis codes,gender,age,length of hospital stay,hospitalization costs,and whether they progressed to severe Mycoplasma pneumoniae pneumonia(SMPP).Results From 2019 to 2023,a total of 29 045 hospitalized children with MPP were treated,with 6 035 cases(20.8%)identified as SMPP in the 22 hospitals.Trend analysis revealed a rising trend with years in the proportion of SMPP patients(χ2trend=365.498,P<0.001).Among the 4 children's hospitals,there were 18 710 cases with MPP,including 4 078 cases(21.8%)of SMPP.The proportion of SMPP patients also showed an increasing trend with years(χ2trend=14.548,P<0.001),and the proportion in 2023(23.0%)was higher than that in previous years with statistical significance.There were statistical differences in the seasonal distribution of MPP cases between different years,with higher proportions in summer and autumn overall.The age distribution of hospitalized MPP children varied among different years,with school-age children accounting for the majority(56.8%)in 2023.There was no difference in the distribution of severe cases between different genders,but there were differences in the proportion of severe cases among different age groups in different years,with a gradual increase in severe cases among children aged 1 to 3 years(χ2trend=191.567,P<0.001).The average length of hospital stay for MPP during the epidemic was higher than that during non-epidemic periods,and there were statistically significant differences in the average length of hospital stay between different years(P<0.001).The individual hospitalization costs during the epidemic were higher than in other years,and there were statistically significant differences in individual hospitalization costs between different years(P<0.001).The total hospitalization costs were still higher in 2019 and 2023.The individual hospitalization costs for SMPP were higher than for non-SMPP cases.Conclusion MPP outbreaks occurred in Shanghai in 2019 and 2023,with the higher proportions in summer and autumn overall.Compared to previous years,the number of hospitalized MPP children in Shanghai was higher in 2023,with a higher proportion of SMPP cases,especially among children under 3 years old.The individual per capita hospitalization expenses for SMPP cases were higher than for non-SMPP cases.

Objective To investigate the clinical characteristics and prognosis of pneumococcal meningitis(PM),and drug sensitivity of Streptococcus pneumoniae(SP)isolates in Chinese children.Methods A retrospective analysis was conducted on clinical information,laboratory data,and microbiological data of 160 hospitalized children under 15 years old with PM from January 2019 to December 2020 in 33 tertiary hospitals across the country.Results Among the 160 children with PM,there were 103 males and 57 females.The age ranged from 15 days to 15 years,with 109 cases(68.1% )aged 3 months to under 3 years.SP strains were isolated from 95 cases(59.4% )in cerebrospinal fluid cultures and from 57 cases(35.6% )in blood cultures.The positive rates of SP detection by cerebrospinal fluid metagenomic next-generation sequencing and cerebrospinal fluid SP antigen testing were 40% (35/87)and 27% (21/78),respectively.Fifty-five cases(34.4% )had one or more risk factors for purulent meningitis,113 cases(70.6% )had one or more extra-cranial infectious foci,and 18 cases(11.3% )had underlying diseases.The most common clinical symptoms were fever(147 cases,91.9% ),followed by lethargy(98 cases,61.3% )and vomiting(61 cases,38.1% ).Sixty-nine cases(43.1% )experienced intracranial complications during hospitalization,with subdural effusion and/or empyema being the most common complication[43 cases(26.9% )],followed by hydrocephalus in 24 cases(15.0% ),brain abscess in 23 cases(14.4% ),and cerebral hemorrhage in 8 cases(5.0% ).Subdural effusion and/or empyema and hydrocephalus mainly occurred in children under 1 year old,with rates of 91% (39/43)and 83% (20/24),respectively.SP strains exhibited complete sensitivity to vancomycin(100% ,75/75),linezolid(100% ,56/56),and meropenem(100% ,6/6).High sensitivity rates were also observed for levofloxacin(81% ,22/27),moxifloxacin(82% ,14/17),rifampicin(96% ,25/26),and chloramphenicol(91% ,21/23).However,low sensitivity rates were found for penicillin(16% ,11/68)and clindamycin(6% ,1/17),and SP strains were completely resistant to erythromycin(100% ,31/31).The rates of discharge with cure and improvement were 22.5% (36/160)and 66.2% (106/160),respectively,while 18 cases(11.3% )had adverse outcomes.Conclusions Pediatric PM is more common in children aged 3 months to under 3 years.Intracranial complications are more frequently observed in children under 1 year old.Fever is the most common clinical manifestation of PM,and subdural effusion/emphysema and hydrocephalus are the most frequent complications.Non-culture detection methods for cerebrospinal fluid can improve pathogen detection rates.Adverse outcomes can be noted in more than 10% of PM cases.SP strains are high sensitivity to vancomycin,linezolid,meropenem,levofloxacin,moxifloxacin,rifampicin,and chloramphenicol.[Chinese Journal of Contemporary Pediatrics,2024,26(2):131-138]

Objective To analyze the epidemiological and clinical characteristics of patients with monkeypox.Methods Data of 17 patients with monkeypox hospitalized in a hospital in Nanning City from July to October 2023 were collected retrospectively.The epidemiological history,clinical manifestations,laboratory examinations,treat-ment and prognosis were analyzed and summarized.Results All 17 patients were male,with a median age of 28 years old.Fifteen(88.2％)patients were men who had sex with men(MSM)within 21 days prior to onset.Major clinical manifestations were rash and fever.Rashes distributed mainly in the anus,perineum and genitals(82.4％),followed by the trunk and limbs(52.9％),head and face(35.3％),while soles and palms were rare.Some patients had swollen inguinal lymph nodes.All patients were discharged from hospital after improvement,with an average hospital stay of 7 days.Conclusion The monkeypox epidemic in Nanning area of Guangxi occurs mainly in MSM population,with fever and rashes as the major symptoms.All patients have mild disease and good prognosis.

Objective To describe the changing trend and related factors of prevalence rates of healthcare-associa-ted infection(HAI)in a tertiary hospital in the past 10 years,and analyze the influencing factors for HAI.Methods A cross-sectional survey on HAI was conducted for 10 consecutive years from 2013 to 2022(one day was selected as the survey day each year),data were collected.The distribution and related factors of prevalence rates of HAI were analyzed by trend-x2 test and Pearson correlation coefficient.Multivariate logistic regression and multilayer percep-tron(MLP)models were constructed to analyze the independent effect and significance of factors.Results From 2013 to 2022,the prevalence rates of HAI ranged from 4.66％to 8.07％in this hospital,showing a linear upward trend.The proportions of ICU patients and utilization rate of central venous catheters within 2 days before the sur-vey showed linear upward trends,while the proportion of patients with urinary catheters within 2 days before the survey and proportion of patients undergoing surgery within 30 days before the survey decreased.The MLP model revealed that the top 3 important factors for HAI were length of hospital stay＞10 days,admission in ICU,and in-dwelling central venous catheters within 2 days before the survey.Multivariate logistic regression model indicated that length of hospital stay＞10 days,indwelling central venous catheters or urinary catheters within 2 days before the survey,surgery within 30 days before the survey,and admission in ICU were independent influencing factors for HAI.Conclusion The incidence of HAI in this hospital presents a linear increase in recent 10 years,the causes should be further analyzed and the direction of intervention should be determined through targeted surveillance.Adopting trend test statistical analysis method,logistic regression,MLP multi-factor model can further explore the data value of HAI prevalence survey.

Objective To construct the demand model of four types of medical resources including beds in hospi-tal,beds in intensive care unit(ICU),ventilators and medical human resources during the major infectious disease epidemic events,simulate and analyze the treatment of infectious diseases when different medical resources are in short supply.Methods Based on the susceptible-exposed-infectious-recovered(SEIR)model,considering the infec-tivity of infected persons,the susceptibility of the population and the immunity of convalescents,the characteristics of asymptomatic COVID-19 patients and different clinical types,the"COVID-19 infection-hospitalization model"was constructed.By collecting and setting the parameters of disease transmission,clinical course and medical re-source shortage scenarios,an analysis model of allocation and supply of urban medical resources during infectious di-sease epidemic events was initially formed based on Anylogic platform,the supply and demand of medical resources during infectious disease events in different scenarios were analyzed.Results In the non-intervention scenario,the peak time of bed demand was on the 107th day,and the peak value was 160.92 beds per thousand people;the peak time of ventilator demand was on the 122nd day,and the peak value was 5.61 units per thousand people;the peak time of ICU bed demand was on the 117th day,and the peak value was 12.78 beds per thousand people;the peak time of the demand for medical human resources was on the 109th day,and the peak value was 151.12 persons per thousand persons.The simulation results suggested that there were some differences in the impact of different medi-cal resources on the outcome of medical treatment.Conclusion This study constructs an analytical tool for the allo-cation and supply of urban medical resources under the epidemic events of infectious diseases,and the results of mul-tiple simulation experiments suggest that bed resources and medical human resources play more important roles in the outcome of medical treatment.

Objective To investigate the effect of remote ischemic preconditioning(RIPC)on major adverse cardiovascu-lar events(MACE)in elderly patients with hip fracture 1 year after operation.Methods Total of 314 elderly patients with hip fracture of grade Ⅱ and Ⅲ for American Society of Anesthesiologists(ASA)were treated by surgical operation from April 2015 to May 2020 including 116 males and 198 females,the age ranged from 60 to 76 years old.The subjects were divided into in-tervention group and control group according to whether received RIPC.Among them,157 cases in intervention group included 56 males and 101 females with an average age of(68.12±7.13)years old and 157 cases in control group included 60 males and 97 females with an average age of(68.24±7.05)years old.Both groups were given routine anesthesia.The intervention group was treated with RIPC on the basis of routine anesthesia.The MACE events 1 year after operation in two groups were com-pared and analyzed.Results The OR values of RIPC for myocardial infarction,heart failure,stroke,nonfatal cardiac arrest,coronary revascularization,severe arrhythmia,peripheral artery thrombosis,readmission of cardiovascular disease,and all-cause death in patients with hip fracture one year after operation were 1.269,1.304,0.977,1.089,1.315,1.335,0.896,0.774,1.191,respectively,but there was no significant difference(P＞0.05).Conclusion RIPC did not significantly affect and change the occurrence of major cardiovascular adverse events within 1 year after hip fracture surgery.The long term impact of RIPC on clinical cardiovascular outcomes in non cardiac surgery needs to be confirmed in appropriate randomized clinical trials.

Objective To explore clinical effect of manipulation reduction combined with vertebral plasty on osteoporotic compression fractures(OVCFs).Methods Totally 61 patients with OVCFs treated from January 2022 to March 2024 were randomly divided into self-made spinal locator positioning with manipulation reduction group(treatment group)and traditional Kirchner positioning group(control group).There were 30 patients in treatment group,including 4 males and 26 females,aged from 61 to 87 years old with an average of(73.61±7.17)years old;body mass index(BMI)ranged from 15.24 to 28.89 kg·m-2 with an average of(23.90±3.20)kg·m-2;bone mineral density T value ranged from-4.90 to-2.50 SD with an avergae of(-3.43±0.75)SD;fracture to operation time was 6.50(4.00,10.25)d;10 patients were grade Ⅰ,13 patients were grade Ⅱ,and 7 patients were grade Ⅲ according to Genant classification of fracture compression.There were 31 patients in control group,in-cluding 7 males and 24 females,aged from 61 to 89 years old with an average of(73.63±8.77)years old;BMI ranged from 18.43 to 27.06 kg·m-2 with an average of(23.67±2.35)kg·m-2;bone mineral density T value ranged from-4.60 to-2.50 SD with an avergae of(-3.30±0.68)SD;fracture to operation time was 6.00(3.00,8.00)d;1l patients were grade Ⅰ,9 patients were grade Ⅱ,and 11 patients were grade Ⅲ according to Genant classification of fracture compression.The puncture times,X-ray fluoroscopy times and puncture time between two groups were observed and compared.Visual analogue scale(VAS),Japanese Orthopaedic Association(JOA)and timed up and go test(TUGT)were observed and compared before operation,3 d and 1 month after operation.Results All patients were followed up for 1 to 3 months with an average of(2.10±0.80)months.Puncture times,X-ray fluorosecopy times and puncture time in treatment group were 5.00(4.00,6.00)times,(29.53±5.89)times and 14.83(12.42,21.20)min,respectively,while those in control group were 7.00(6.00,8.00)times,(34.58±5.33)times,22.19(17.33,27.01)min,treatment group was better than those of control group(P＜0.05).There were no significant differences in preoperative VAS,JOA and TUGT between two groups(P＞0.05).VAS,JOA and TUGT in both groups were sig-nificantly improved after opeation(P＜0.05).On the third day after operation,JOA score of treatment group was 23.00(20.75,25.00),which was higher than that of control group 20.00(19.00,23.00)(P＜0.05).TUGT of treatment group was 6.26(5.86,6.57)s,which was better than that of control group 6.90(6.80,7.14)s(P＜0.05).Bone cement leakage occurred with 1 patient in treatment group and 2 patients in control group.Conclusion The optimal scheme of self-made spinal locators for lo-cating descending verteboplasty combined with traditional Chinese medicine reduction manipulation for OVCF patients could reduce the number of intraoperative puncture times,shorten puncture times and reduce number of X-ray fluoroscopy times,and have advantages over the simple positioning of Kirschn's needle in restoring short-term lumbar function and standing and walk-ing ability of postoperative patients.
