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.
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.
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.
ObjectiveTo describe the cancer incidence and mortality in Henan cancer registries in 2014.MethodsRegistration data (including incidence, mortality and population data) were evaluated according to the criteria of quality control of cancer registry. The incidence, mortality, and cumulative rate (0 to 74 years old) were calculated and stratified by area (urban/rural), gender, and age. Chinese Population Census in 2000 and Segi’s Population were used for age-standardized incidence and mortality rates.ResultsThe total covered population of the 27 cancer registries in 2014 was 21 044 835, accounting for 19.73% of Henan's total population at the end of 2014. The crude incidence rate in Henan cancer registration areas was 252.79/100 000 (males 273.55/100 000, females 230.70/100 000). Age-standardized incidence rates by Chinese standard population and by world standard population were 205.27/100 000 and 203.78/100 000 with the cumulative incidence rate (0 to 74 years old) of 24.17%. The cancer mortality in Henan was 156.58/100 000 (188.10/100 000 in males and 123.02/100 000 in females). The age-standardized incidence rates by Chinese standard population and by world standard population were 123.94/100 000 and 123.80/100 000, and the cumulative incidence rate (0 to 74 years old) was 14.30%. Lung cancer, gastric cancer, esophageal cancer, liver cancer, breast cancer, colorectal cancer, cervical cancer, encephala, leukemia and thyroid cancer were the most common cancers, accounting for approximately 83% of all cancer cases in urban and rural areas. Lung cancer, gastric cancer, esophageal cancer, liver cancer, colorectal cancer, breast cancer, encephala, leukemia, pancreatic cancer and cervical cancer accounted for approximately 88% of all cancer deaths.ConclusionsThe age-standardized incidence and mortality in Henan are above the national level. The common cancers in Henan are lung cancer, female breast cancer and digestive system cancers. The strategy of cancer prevention and control in Henan should be implemented depending on pratical situations.
Objective To investigate the incidence of urolithiasis in infants aged 0-3 years old fed by milk powder tainted with melamine in the middle area of the Anhui province, as well as its relationship to gender, age, milk powder consumption and drinking water. Methods Questionnaires were distributed to 1079 infants who were screened for urolithiasis by ultrasound examination from September 25, 2008 to October 17, 2008. Data was collected by Epidata and analyzed by SPSS 13.0 software. Results A total of 646 (59.87%) male infants and 433 (40.13%) female infants underwent ultrasound examination in Anhui Provincial Hospital. Of these, 86 infants were diagnosed with urolithiasis with an incidence of 7.97%, including 62 males (72.09%) and 24 females (27.91%). The mean age of those infants with urolithiasis was 1.85±0.77, and all of calculus was located in kidney. The relationship between the incidence of urolithiasis and gender, age, drinking water, feeding bottle sanitation, birth status, as well as the amount of milk powder intake was assessed by using the Pearson Chi-square test. Results showed that significant differences were noted in the incidence of urolithiasis among infants of different genders or with different drinking water sources (Plt;0.05). The result of multiple logistic regression analyses indicated that gender was related to the incidence of urolithiasis (Plt;0.05). The incidence of urolithiasis in female infants was only 58.7% of that in male infants (OR 0.587, 95%CI 0.359 to 0.959). Conclusion The incidence of urolithiasis in infants aged 0-3 years of old in the middle area of Anhui province is relatively high and has anatomical specificity. Further data during the follow-up of these cases should be collected.
ObjectiveTo explore the regional and urban-rural disparities in the hypertension incidence of Chinese adults. MethodsBased on the data from the China Health and Nutrition Survey (CHNS), as well as the consumption level and altitude data from the National Bureau of Statistics and government official website, a robust multilevel Poisson regression was performed to explore the regional and urban-rural disparities in the hypertension incidence of Chinese adults, according to data and design types. ResultsAccording to the inclusion and exclusion criteria, 11 579 subjects and totaling 50 957 lines of data were enrolled. The 24 years follow-up results indicated that the crude incidence density of hypertension was 37.08/1 000 person years, with 40.51/1 000 person years for males and 34.13/1 000 person years for females. The robust multilevel Poisson regression results indicated that, by adjusting the high-level factors such as time, the proportion of the community mainly engaged in agricultural labor, and the consumption level of subjects, as well as sociodemographic characteristics such as age and gender, the Middle (RR=1.20, 95%CI 1.04 to 1.39), Northeast (RR=1.25, 95%CI 1.03 to 1.52), and Eastern (RR=1.25, 95%CI 1.05 to 1.48) China had a higher risk of developing hypertension than the Western China. The risk of hypertension in urban area was lower than that in rural area (RR=0.87, 95%CI 0.77 to 0.96). ConclusionThe incidence density of hypertension in China is relatively high, and male is higher than female. The incidence of hypertension in the Western China is lower than that in the Middle, Northeast and Eastern China, and urban area is lower than rural area.
ObjectiveThis study aimed to analyze the disease burden of pancreatitis in China from 1990 to 2019 and to provide references for the prevention and treatment of pancreatitis. MethodsThe data were obtained from the Global Burden of Disease Study 2019 (GBD 2019). The incidence, mortality, disability-adjusted life years (DALYs), years of life lost (YLLs), years lived with disability (YLDs) and their corresponding age-standardized rate, and annual average percentage change (AAPC) were selected as the main indicators to compare the burden of pancreatitis in China, the United States and globally from 1990 to 2019. ResultsIn 2019, the age-standardized incidence, mortality, DALY, YLL, and YLD rates in China were 26.76/100 000, 0.59/100 000, 16.09/100 000, 14.61/100 000, and 1.48/100 000, respectively, and decreased by 8.94%, 45.33%, 49.12%, 50.98%, and 18.49%, respectively, compared with those in 1990. The burden of pancreatitis in China gradually increased with age, but was lower than that in the United States and globally. The DALY due to alcohol continually increased in China, the United States, and globally. ConclusionFrom 1990 to 2019, the burden of pancreatitis in China shows a decreasing trend and is lower than that in the United States and globally. However, the disease burden caused by alcohol and aging is increasing; therefore, effective measurements to alleviate the burden of pancreatitis in China are needed.
ObjectiveTo analyze the prevalence of muscle and tendon injuries in Chinese from 2005 to 2019. MethodsUsing Joinpoint regression model and age-time-cohort model, the average annual percent change (AAPC) was used to analyze the incidence of muscle and tendon injury in Chinese from 2005 to 2019. The influence of age, period and birth cohort on the incidence of muscle and tendon injury was analyzed by sex. ResultsFrom 2005 to 2019, the incidence of muscle and tendon injury in Chinese residents increased (AAPC=2.0%, P<0.05), and the AAPC of females was higher than that of males (AAPC values were 2.1% and 1.9%, respectively, P<0.05). The results of age-time-cohort model showed that the age effect, period effect and cohort effect coefficient were statistically significant. The age effect and cohort effect coefficient fluctuated, and the period effect coefficient increased continuously. The period effect is dominant in three effects. ConclusionThe incidence of muscle and tendon injuries in Chinese residents has increased rapidly. Children aged 5 to 9, people aged 20 to 29 and elderly women aged 85 to 94 are the key groups.
ObjectiveTo systematically review the risk of hemorrhage in pregnant cerebral arteriovenous malformation (CAVM) patients. MethodsThe Web of Science, PubMed, Cochrane Library, WanFang Data, VIP and CNKI databases were electronically searched to collect clinical studies related to hemorrhage in pregnant CAVM patients from inception to June, 2023. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using Stata 13.1 and R 4.0.4 software. ResultsA total of 13 studies involving 2 273 patients were included. The results of meta-analysis showed that the pooled incidence of hemorrhage in pregnant CAVM patients was 0.18 (95%CI 0.12 to 0.24). The subgroup analyses were carried out based on world regions and the study duration, with the higher pooled incidence of 0.37 (95%CI 0.05 to 0.80) in Europe and 10 to 20 years of study duration of 0.37 (95%CI 0.17 to 0.57). Conclusion Current evidence shows that the incidence of hemorrhage in pregnant CAVM patients is about 18%. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo analyze the incidence and risk factors of tuberculosis in the city of Mianyang based on data from active cases.MethodsFrom March 2018 to April 2019, 199 182 residents were selected for the study. Data were collected using a questionnaire, digital radiography (DR), physical examination and laboratory tests. The incidence of tuberculosis was estimated, and multivariate logistic regression was used to identify factors associated with the disease.ResultsThroughout the process, 103 residents were diagnosed with active tuberculosis, corresponding to an incidence of 51.71 per 100 000. Risk of tuberculosis was significantly higher among individuals who were over age 60 (OR=1.74, 95%CI 1.11 to 2.73, P=0.02), males (OR=4.39, 95%CI 2.74 to 7.04, P<0.001), medical workers (OR=11.18, 95%CI 2.99 to 41.84, P<0.001), and those with a history of tuberculosis (OR=16.43, 95%CI 8.10 to 33.33, P<0.001). Conversely, individuals with higher levels of education were associated with lower risk of tuberculosis: compared to those with primary school or less, those with a junior high school education had an OR of 0.53 (95%CI 0.30 to 0.88, P=0.02); high school/technical school had an OR of 0.36 (95%CI 0.15 to 0.92, P=0.03); junior college or above had an OR of 0.23 (95%CI 0.06 to 0.88, P=0.04).ConclusionsAnalyzing tuberculosis epidemiology based on active cases can help detect the disease as well as control or even prevent epidemics. Individuals who are more senior, males, medical workers, with a history of tuberculosis, and those with lower levels of education may be at higher risk of the disease. These results may improve screening efforts and allow timely intervention.
