Objective To analyze the incidence and mortality of acute viral hepatitis in China, project its trends from 2022 to 2030, and provide valuable insights for the prevention and control of viral hepatitis. Methods The incidence and mortality rates of acute viral hepatitis in China from 1990 to 2021 were extracted from the Global Burden of Disease 2021 database. The change rates and the estimated annual percentage change (EAPC) for each indicator were calculated. Additionally, an autoregressive integrated moving average (ARIMA) model was used to project the incidence and mortality of acute viral hepatitis in China from 2022 to 2030. Results From 1990 to 2021, the incidence rates of acute hepatitis A (AHA), acute hepatitis B (AHB), acute hepatitis C (AHC), and acute hepatitis E (AHE) in China all showed a declining trend (EAPC=−1.980%, −2.664%, −2.078%, −1.686%; P<0.05), with a particularly marked decrease in mortality (EAPC=−11.662%, −7.411%, −12.541%, −7.504%; P<0.05). According to ARIMA model projections, the incidence rates of AHA and AHB were expected to continue declining from 2022 to 2030, while the incidence rates of AHC and AHE were expected to rise. In 2030, the projected incidence rates of AHA, AHB, AHC, and AHE were 890.425/100000, 824.158/100000, 59.202/100000, and 300.377/100000, respectively. The mortality rates of AHA, AHC, and AHE were projected to remain stable from 2022 to 2030, while the mortality rate of AHB was expected to decline. In 2030, the projected mortality rates of AHA, AHB, AHC, and AHE were 0.002/100000, 0/100000, 0.004/100000, and 0.011/100000, respectively. Conclusions From 1990 to 2021, the overall incidence and mortality of acute viral hepatitis in China showed a downward trend. However, the incidence rates of AHC and AHE may present an upward trend in the future, which suggests that the government and relevant health authorities should adjust their prevention and control strategies in a timely manner.
ObjectiveTo systematically review the trend of tuberculosis among Chinese students. MethodsPubMed, Web of Science, EMbase, CBM, WanFang Data and CNKI databases were electronically searched to collect cross-sectional studies on the incidence and trend of tuberculosis among students in China from inception to August 2021.

Objective To explore impact of climate change on aortic dissection and to put forward a new way about prediction and prevention of aortic dissection. Methods We retrospectively analyzed the characteristics of acute aortic dissection patients came from Hebei province in Fuwai Hospital between 2010 and 2016 year. Meanwhile, we collected monthly maximum temperature, minimum temperature, average temperature, average pressure, amount of rainfall, sunshine, humidity and other meteorological data. Generalized model was implied to explore climate change and the incidence of aortic dissection. Results A total of 1 121 acute aortic dissection patients from Hebei province were admitted in Fuwai Hospital during the period of 6 years. There were 774 patients were type A aortic dissection, and 347 patients were type B aortic dissection. The average age was 51.4±12.0 years. There were 873 males and 248 females. There were 889 (79.3%) patients with hypertension, 99 (8.83%) with Marfan syndrome. It was found that temperature, humidity and air pressure were all statistically significant for indication aortic dissection through single variable analysis (P<0.01). The temperature was only variable by one-way analysis of variance (P<0.01). The lowest temperature has the best predictive effect on the occurrence of aortic dissection. The relative risk was 1.02 with 95% confidence interval 1.02 to 1.03. Conclusion The change of climatic conditions can affect the occurrence of aortic dissection, and the lowest temperature is an important trigger factor for aortic dissection onset.
Objective To summary the incidence rate and trends of cancers in China. MethodsBy compiling and analyzing the Chinese Cancer Registry Annual Report from 2008 to 2021, we summarized the regional and population distribution characteristics of overall and high-incidence rate cancers in China and analyzed influencing factors. ResultsFrom 2005 to 2018, the overall crude incidence of cancers in China showed a continuous upward trend. The incidence rate in the eastern region (incidence rate was 353.26/100 000 in 2018, the following data were crude incidence rate in 2018) was significantly higher than those in the central (269.47/100 000) and western regions (253.71/100 000), while the incidence rates in the central and western regions were closer. 2005–2018, the incidence rates of male was higher than that of female, and the population aged 80 years old or older (2 741.02/100 000) had the highest incidence rate of cancers, and the incidence rate of people aged 0–14 years old (41.38/100 000) was the lowest. From 2005–2018 (except for 2009), lung cancer (65.05/100 000), gastric cancer (27.03/100 000), liver cancer (27.42/100 000), colorectal cancer (30.51/100 000), and breast cancer (43.02/100 000) were the top 5 highest incidence rates of China’s cancers, of which lung cancer ranked the first in different regions, and the ranking of other cancers varied in different regions. The top 5 cancers in males’ incidence rates from 2005 to 2018 were lung cancer (83.45/100 000), gastric cancer (37.12/100 000), liver cancer (40.02/100 000), colorectal cancer (35.32/100 000) and esophageal cancer (26.30/100 000); the top 5 cancers in females’incidence rates had changed a lot in different years, breast cancer, lung cancer, colorectal cancer, gastric cancer, liver cancer, thyroid cancer and cervical cancer had all been in the top 5, for example, in 2018, the top 5 cancers in female were lung cancer (46.10/100 000), breast cancer (43.02/100 000), colorectal cancer (25.56/100 000), thyroid cancer (24.60/100 000) and cervical cancer (18.10/100 000).ConclusionsThe crude incidence rate of cancers in China continues to rise, with the cancer spectrum showing new characteristics that combine high-incidence rate cancers in developed countries (e.g., breast cancer, colorectal cancer) with common cancers in developing countries (e.g., gastric cancer, liver cancer). The situation of cancer prevention and control remains challenging.
ObjevtiveThe morbidity of intensive care unit-acquired swallowing disorder (ICU-ASD) was clarified through meta-analysis by synthesizing previous evidence, in order to provide an evidence-based basis for early identification and intervention of ICU-ASD. Methods A computerized search of PubMed, Embase, Web of Science, The Cochrane Library, CHINAL, China Knowledge Network, Wanfang Data Knowledge Service Platform, and Chinese Science and Technology Journal Database was conducted to retrieve the relevant literature on the morbidity of ICU-ASD published in China and abroad from the database establiment to December 2022. Considering the quality of the included literature, the Chinese database excluded master's theses and non-core journals. Meta-analysis of morbidity was performed using Stata 12.0. Results A total of 19 papers, including 4291 patients, were included. Meta-analysis showed that the overall morbidity of ICU-ASD was 36% [95% confidential interval (CI) 26% - 46%; I2=97.62%, P<0.01]. Subgroup analyses showed that the morbidity of ICU-ASD in Asian, European, South American, and North American was 39% (95%CI 28% - 50%), 23% (95%CI 8% - 44%), 52% (95%CI 46% - 57%), and 39% (95%CI 20% - 61%), respectively; and that the morbidity of male and female ICU-ASD was 36% (95%CI 24% - 48%) and 33% (95%CI 22% - 45%), respectively; the morbidity of ICU-ASD was 41% (95%CI 30% - 52%) and 31% (95%CI 18% - 44%) in the patients with and without hypertension, respectively; the morbidity of ICU-ASD was 58% (95%CI 42% - 73%) and 51% (95%CI 36% - 66%) in the patients with and without respiratory disease respectively; the morbidity of ICU-ASD in the patients with and without diabetes mellitus was 37% (95%CI 24% - 51%) and 39% (95%CI 28% - 51%), respectively; the morbidity of ICU-ASD in the patients with and without renal disease was 40% (95%CI 23% - 59%) and 35% (95%CI 24% - 46%), respectively; the morbidity of ICU-ASD in the patients with intubation caliber ≤7.5 mm and >7.5 mm was 31% (95%CI 19% - 45%) and 37% (95%CI 22% - 54%), respectively; the morbidity of ICU-ASD in the patients with and without heart failure was 58% (95%CI 30% - 84%) and 36% (95%CI 23% - 51%), respectively; and the morbidity of ICU-ASD in patients with and without arrhythmia was 36% (95%CI 11% - 65%) and 31% (95%CI 21% - 42%), respectively; the morbidity of ICU-ASD in the patients with and without neurologic disease was 48% (95%CI 24% - 72%) and 34% (95%CI 15% - 57%), respectively. Begg's test P<0.05, Egger's test P<0.05, suggesting publication bias in the study, and the cut-and-patch method corrected for an overall incidence result of 27% (95%CI 18% - 36%). Conclusions Meta-analysis reveals an overall morbidity of 36% for ICU-ASD and 27% for the cut-and-patch correction. Subgroup analysis reveals that the morbidity of ICU-ASD is significantly higher in patients with hypertension, heart failure, and neurological disorders than in patients without these disorders. Current evidence suggests that the prevalence of ICU-ASD is high and needs to be taken seriously. Timely screening and assessment of swallowing disorders is recommended for intensive care unit patients, especially those with hypertension, heart failure, and neurological disorders.
ObjectivesTo analyze the trend of incidence and mortality of bladder cancer from 1990 to 2017 and the effects of age, time period and birth cohort on bladder cancer incidence and mortality.MethodsData on age-standardized incidence rate (ASIR) and age-standardized death rate (ASDR) of bladder cancer from 1990 to 2017 were extracted from the Global Burden of Disease 2017 (GBD 2017) database. Joinpoint regression model was used to analyze the average annual percentage change of ASIR and ASDR of bladder cancer. The age-period-cohort model was established to analyze the age, period and birth cohort effects on ASIR and ASDR of bladder cancer.ResultsFrom 1990 to 2017, both ASIR and ASDR of bladder cancer decreased slightly. ASIR decreased from 6.42 per 100 000 in 1990 to 6.04 per 100 000 in 2017, with an average annual percentage change of −0.9% (−1.0% to −0.8%), and ASDR decreased from 3.15 per 100 000 in 1990 to 2017 2.57/100 000, with an average annual percentage change of −0.4% (−0.4% to −0.3%). The age-period-cohort model results showed that as age increased, the risk of bladder cancer incidence and mortality increased; as the birth cohort progressed, the risk of bladder cancer morbidity and mortality decreased. The time period had little effect on the incidence and mortality of bladder cancer.ConclusionsThe incidence and mortality of bladder cancer are declining globally. On the other hand, the increase of the aging global population could reverse the incidence and mortality trend, active measures should be taken to address the adverse effects of aging.
