Objective To investigate the incidence of urolithiasis in infants aged 0-3 years old fed by melaminetainted milk powder in Gansu province. Methods Questionnaires were distributed to 7 856 infants who were screened for urolithiasis in the Second Hospital of Lanzhou University by ultrasound examination from September 25, 2008 to November 15, 2008. Data were collected by Excel and analyzed by SPSS 13.0 software. Results A total of 4 090 (52.06%) male infants and 3 766 (47.94%) female infants underwent ultrasound examination in the Second Hospital of Lanzhou University. The mean age of the infants with urolithias was 18.30±9.68 months. Of those, 704, including 434 males (61.65%) and 270 females (38.35%), were diagnosed with urolithiasis, with an incidence of 8.96%, and 99.14% of calculus was located in kidney. And, 58 aged 0-6 months with an incidence of 3.16%, 218 aged 6-12 months with an incidence of 11.01%, 275 aged 12-24 months with an incidence of 12.55%, and 153 aged 24-36 months with an incidence of 8.27%. The relationship between the incidence of urolithiasis and gender as well as age was assessed by using the Pearson Chi-square test. The results showed significant differences in the incidence of urolithiasis among infants of different genders and different ages (Plt;0.05). The result of multiplelogistic regression analysis indicated that gender was related to the incidence of urolithiasis (Plt;0.05). Conclusion The incidence of urolithiasis in the infants aged 0-3 years old in Gansu province is relatively high. The incidence of urolithiasis focuses on the infants aged 6-24 months and has anatomical specificity.
Objective To analyze the incidence and mortality of asthma in China from 1990 to 2019, and to explore the influence of age, period and cohort on the incidence and mortality of asthma. Methods Using the Global Burden of Disease (GBD) 2019 database, the incidence and mortality of asthma in China from 1990 to 2019 were analyzed, and the time variation trend of age-standardized incidence and mortality was analyzed by using Joinpoint software, and the average annual variation percentage was calculated. The age-period-cohort model was constructed to analyze the influence of age, period and birth cohort on the incidence and mortality trend of asthma. Results In 2019, the incidence of asthma in China was 264.44/100 000, and the mortality rate was 1.74/100 000. The incidence rate of asthma in males (300.94/100 000) and mortality rate (1.99/100 000) were higher than those in females (226.51/100 000 and 1.49/100 000). From 1990 to 2019, the age-standardized incidence of asthma in China showed a downward trend, but the trend was not statistically significant (P>0. 05), and the age-standardized mortality showed a downward trend, with an average annual decrease of 4.90%, with a statistically significant trend (P<0.05). The results of age effect showed that the incidence of asthma in China showed a downward trend, and the death first showed a downward trend, and then increased in the age group of 55-59. The results of period effect show that the risk of asthma is decreasing, and then it is increasing from 2015 to 2019, and the risk of asthma mortality is decreasing. The results of cohort effect show that the later people are born, the lower the risk of asthma onset and death. The death of asthma is attributed to behavioral risk, high body mass index and tobacco, and the occupational risk tends to decrease. ConclusionsFrom 1990 to 2019, the incidence and mortality of asthma in China showed a decreasing trend, and the incidence and mortality of men were higher than that of women. The risk factors of behavioral risk, high body mass index and tobacco were still on the rise, so corresponding measures should be taken to carry out early screening, early detection, and early treatment for key populations.
Objective To investigate the incidence and management of CTEPH in the Department of Pulmonary and Critical Care Medicine in Xijing Hospital to enrich the epidemiological data of chronic thromboembolic pulmonary hypertension (CTEPH) in China.Methods We conducted a retrospective study to investigate the incidence and management of CTEPH in the Department of Pulmonary and Critical Care Medicine in Xijing Hospital from 2008 to 2012. Results The incidence of CTEPH was 5.24% . About 62.90% of venous thromboembolism/pulmonary embolism (VTE/PE) patients were unprovoked, and about 53.85% of CTEPH patients was unprovoked. About 38% of CTEPH patients had no history of VTE, and 62% of CTEPH patients had no history of acute pulmonary embolism. None of the CTEPH patients was treated by pulmonary thromboendarterctom (PTE) , and about 53.85% of patients were only given anticoagulant monotherapy. Conclusions The incidence of CTEPH is higher in our hospital than reported. This phenomenon may be related to the lack of awareness of risk factors of CTEPH and the insufficient thrombolytic and anticoagulant therapy to acute pulmonary embolism. It’s very urgent to standardize the diagnosis and management of CTEPH in pulmonologists.
Objective To investigate the incidence trend of migraine in Chinese from 1990 to 2019 in the global burden of disease database (GBD2019) and its effect on three factors: age, period and cohort. Methods Data were obtained from GBD2019. Joinpoint software was used to analyze the changes in migraine incidence. We analyzed the age-period-cohort (APC) model of migraine in the Chinese population with Stata 17.0 software and estimated the effect of age, period, and cohort on migraine incidence. Results From 1990 to 2019, the standardized incidence of migraine in the general population, and in men and women in China showed a fluctuating upwards trend, and the average annual percentage changes were 0.23%, 0.27% and 0.21%, respectively. The APC model showed that from 1990 to 2019, the risk of migraine in China decreased with the increase of age, showed a downward trend with the increase of the period, and increased with the increase of the birth cohort, indicating that the cohort effect played a dominant role in the risk of migraine in the current period, and the risk of women in the rear of the birth cohort began to be gradually higher than that of men. Conclusion The incidence of migraine in Chinese population is on the rise from 1990 to 2019, and the younger the age, the earlier the period, and the lower the birth cohort, the greater the risk of migraine, suggesting that the prevention and treatment of migraine in women aged 10 to 54 years should be strengthened to further reduce the incidence of migraine in China.
ObjectiveThis study aims to analyze the trends in Parkinson’s disease incidence rates among the elderly population in China from 1990 to 2021 and to forecast incidence growth over the next 20 years, providing. MethodsJoinpoint regression and age-period-cohort models were employed to analyze temporal trends in Parkinson’s disease incidence, and the Nordpred model was used to predict case numbers and incidence rates among the elderly in China from 2022 to 2044. ResultsFindings indicated a significant increase in Parkinson’s disease incidence among China’s elderly population from 1990 to 2021, with crude and age-standardized incidence rates rising from 95.37 per 100 000 and 111.05 per 100 000 to 170.52 per 100 000 and 183.91 per 100 000, respectively. Predictions suggested that by 2044, the number of cases will rise to approximately 878 264, with the age-standardized incidence rate reaching 223.4 per 100 000, and men showing significantly higher incidence rates than women. The rapid increase in both cases and incidence rates indicated that Parkinson’s disease will continue to impose a heavy disease burden on China’s elderly population. ConclusionThe burden of Parkinson’s disease in China’s elderly population has grown significantly and is expected to worsen. To address the rising incidence rates effectively, it is recommended to enhance early screening and health education for high-risk groups, improve diagnostic and treatment protocols, and prioritize resource allocation to Parkinson’s disease prevention and care services to reduce future public health burdens.
Incidence rate is a common effect measure. The incidence rate ratio refers to the ratio of two different incidence rates. It is used to compare the difference in the number of cases per unit person-time between two groups. RevMan software can not perform a meta-analysis with the incidence rate ratio as the effect size at present. A set of simulation data was used to demonstrate a meta-analysis process with the incidence rate ratio as the effect size by using the meta package of R Studio software in this article.
ObjectiveTo systematically review the incidence of internet addiction disorder among college students in China.MethodsPubMed, EMbase, VIP, WanFang Data and CNKI databases were electronically searched to collect cross-sectional studies on incidence rate of college students’ internet addiction in China from inception to February 2020. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by Stata 16.0 software.ResultsA total of 65 cross-sectional studies involving 87 702 subjects were included. The results of meta-analysis showed that: the overall incidence of college students’ internet addiction in China was 10.7% (95%CI 9.6% to 11.8%). The incidence of internet addiction from 2011 to 2018 (11.7%, 95%CI 10.2% to 13.2%) was higher than that from 2005 to 2010 (9.6%, 95%CI 8.1% to 11.1%). The incidence in male students (14.6%, 95%CI 13.1% to 16.0%) was higher than that in female students (6.9%, 95%CI 5.9% to 7.8%). The incidence of urban students (12.2%, 95%CI 9.3% to 15.2%) was higher than that of rural students (9.0%, 95%CI 7.3% to 10.6%). The incidence of students who were not satisfied with their major (16.2%, 95%CI 5.5% to 26.8%) was higher than that of satisfied (5.0%, 95%CI 1.3% to 8.8%). The incidence of students with poor academic performance (29.4%, 95%CI 11.9% to 47%) was higher than of excellent academic performance (4.1%, 95%CI 1.9% to 6.4%).ConclusionsThe incidence rate of internet addiction among college students in China shows an obvious upward trend. There are differences in the incidence rates of internet addiction among college students in different regions. The incidence rates of internet addiction are different among different genders, degree of satisfaction with their majors and academic achievements.
Objective To investigate the incidence of urolithiasis in the children who ingested milk powder tainted with melamine in the Chengdu area. Methods A total of 5 795 infants were screened for urolithiasis by ultrasound examination from September 17, 2008 to December 9, 2008. The data were analyzed using SPSS 13.0 software.Results Twenty-four children were diagnosed with urolithiasis with an incidence of 0.41%, including 12 males and 12 females. The mean age of those children with urolithiasis was 2.35±1.68 years old. No significant difference was shown in the incidence of urolithiasis between males and females (Pgt;0.05). The incidence of urolithiasis in the infants aged 0-3 was significantly higher than that in the children who were more than 3 years old (Plt;0.05). Conclusion The incidence of urolithiasis in the infants aged 0-3 in Chengdu and the surrounding areas is relatively high. Further data should be collected during the follow-up of these cases.
ObjectiveTo survey the current situation of post-intensive care syndrome (PICS) among patients in respiratory intensive careunit (RICU), and explore the effect factors of PICS.MethodsBy convenience sampling, 125 patients in the RICU of Peking University First Hospital were recruited in the study. The patients were tested for PICS using Mini-mental State Examination (MMSE), Confusion Assessment Method for the ICU (CAM-ICU), Hospital Anxiety and Depression Scale (HADS), Medical Research Council (MRC), Activities of Daily Living (ADL), Pittsburg Sleep Quality Index (PSQI), Fatigue Scale-14 (FS-14), including three aspects of cognition, psychology and physiology. The effect factors of PICS were measured through researcher-created Questionnaire on Patients’ General Information and Questionnaire on Disease-Related Information.ResultsIn this study, the actual effective sample size was 110 cases, among which 59 cases developed PICS, with an incidence of 53.6%. Logistic regression showed that effect factors of PICS were age, invasive mechanical ventilation time, noninvasive ventilator assisted ventilation time and coronary atherosclerotic heart disease (P< 0.05).ConclusionsThe incidence of PICS in RICU patients is 53.6%, which is at a high level. Advanced age, long duration of invasive mechanical ventilation, long duration of non-invasive ventilator assisted ventilation, and coronary atherosclerotic heart disease are the risk factors of PICS. Medical and nursing staff should pay more attention to PICS, intervene in the risk factors of the patient, and take targeted measures to prevent the occurrence of PICS.
ObjectiveTo systematically review the characteristics of adverse transfusion reaction in Grade Three Class-A hospitals in China, and to provide scientific evidence for related control and prevention work.
MethodsSuch databases as the PubMed, EMbase, The Cochrane Library (Issue 11, 2014), CNKI, VIP, WanFang Data and CBM were searched for studies investigating the characteristics of adverse transfusion reaction with ≥6 months observation time in Grade Three Class-A hospitals in China up to November 2014. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and assessed the methodological quality of included studies. Then, meta-analysis was performed by using the R 3.1.1 software.
ResultsSeventy-two studies involving 1 660 472 cases of blood transfusion were included. The results of pooled analysis showed that the total number of adverse transfusion reaction rate was 0.58% (95%CI 0.48 to 0.69). Sub-group analysis shows that the blood transfusion adverse reaction rates in the eastern, central and western regions were 0.42% (95%CI 0.31 to 0.55), 0.55% (95%CI 0.41 to 0.70), 0.56% (95%CI 0.43 to 0.70), respectively; and there were statistical differences between regions (P<0.05). Different types of adverse transfusion reaction rates were 38.85% (95%CI 34.27 to 43.53) for non hemolytic febrile reaction and 55.67% (95%CI 50.79 to 60.50) for allergic. The adverse reactions incidence of different kinds of blood products transfusion occurred were 0.41% (95%CI 0.32 to 0.50) in red blood cell, 0.57% (95%CI 0.43 to 0.72) in plasma, 1.00% (95%CI 0.73 to 1.30) in platelet. The incidence of adverse reaction of platelet transfusion was significantly higher than that of red blood cell and plasma (P<0.05).
ConclusionThere is a big gap between domestic and foreign blood transfusion adverse reaction reports, therefore comprehensive measures should be taken for further prevention and control.
