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 evaluate the effect of vitamin A (Vit A) supplementation on the morbidity and mortality in children with infectious diseases. Methods We searched Cochrane Library (Issue 1, 2004), MEDLINE (1966-2004.3) and The PedsCCM Evidence-Based Journal Club (1992-2002). Relevant systematic reviews and randomized controlled trials (RCTs) of Vit A supplementation on morbidity and mortality in children with infectious diseases were obtained. Results We collected 107 studies and identified 13 systematic reviews or RCTs. The evidence showed that the effect of Vit A supplementation on morbidity and mortality was affected by the nutritional status of the children. Vit A supplementation given to Vit A deficient children could reduce the morbidity of diarrhea and mortality of measles. However, Vit A supplementation would increase the morbidity of diarrhoea and respiratory infections in children with sufficient nutrition. Conclusions The nutritional status of children correlates with morbidity and mortality of some infectious diseases, and the nutritional status and serum Vit A level should be evaluated before Vit A supplementation applied.
ObjectivesTo systematically review the epidemiological characteristics of post-stroke shoulder pain (PSSP).MethodsPubMed, WanFang Data, CNKI, EMbase, The Cochrane Library and SinoMed databases were electronically searched to collect studies on the morbidity of PSSP from inception to November 30th, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using Stata 15.0 software.ResultsA total of 13 studies were included. The total sample size was 3 514, including 1 357 patients with PSSP. The results of meta-analysis showed that the total morbidity of PSSP was 45.0% with 95%CI 32.0% to 58.0%. The results of subgroup analysis showed that the morbidity of PSSP was 55.5% (95%CI 48.1% to 63.0%) prior to 2010 and 40.6% (95%CI 28.3% to 52.9%) after 2010, respectively. The morbidity of PSSP in Asia was 61.2% (95%CI 51.3% to 71.1%), and in Europe and America was 18.4% (95%CI 9.9% to 26.9%), respectively.ConclusionsCurrent evidence suggests that PSSP has high morbidity, and it may be affected by regional factors. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
ObjectiveTo investigate the clinicopathologic and epidemiological characteristics of patients with gastric cancer at our hospital in the past six years． Methods A total of 958 patients with gastric cancer were selected from January 2004 to December 2009 and clinicopathologic characteristics such as basic data, pathological type, tumor location, and TNM stage were retrospectively analyzed. ResultsOf the 958 patients，697 cases (72.8%) were male and 261 cases (27.2%) were female, and the age ranged from 26 to 91 years old (mean 62.6 years old). The occurrence rate of gastric cancer was higher in the patients of 46-65 years old (49.4%, 473/958) than that in the patients of ≥66 years old (42.3%, 405/958) and ≤45 years old (8.3%, 80/958). Regarding pathologic type, the majority of advanced gastric cancers (70.1%) were Borrmann Ⅱ, the adenocarcinoma and signetring cell carcinoma accounted for 82.3% and 7.8%, respectively. The cancer of gastric cardia accounted for 53.0%. Stagestratified analysis revealed that the majority of gastric cancers (47.4%) were stage Ⅲ. Conclusion①A prevalence of gastric cancer is found in middle, elderly male patients. Poorly differentiated adenocarcinoma in cardia is prominent. ②Patients with high malignant ganstrie cancer are younger. ③The majority of patients who underwent the surgical treatments have advanced or metastatic tumor, therefore it is necessary to improve the early diagnosis of gastric cancer.
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.
ObjectiveTo analyze the epidemic trend of thyroid cancer in China from 2005 to 2018, and understand the estimated epidemiological situation of thyroid cancer in China in 2022 based on the thyroid cancer registration data reported by the National Cancer Registration Center and the China Cancer Registration Annual Report. MethodsThe cases of new thyroid cancer and deaths in China were analyzed according to the data of approximately 700 cancer registries in 2018 and the data of 106 cancer registries from 2005 to 2018, then stratified by sex, age, urban and rural areas, and main regions in China. And the estimated incidence and mortality of thyroid cancer in China in 2022 were analyzed based on the population data in 2020. Results① The age standardized incidence rate (ASIR) and age standardized mortality (ASMR) of thyroid cancer in China from 2005 to 2018: in the whole population, the ASIR showed a relatively rapid upward trend and the ASMR showed a relatively slower upward trend; The ASIR and ASMR of men were lower than those of women and the trend of change was also slower than that of women; The ASIR of thyroid cancer in the whole urban population was markedly higher than that in the rural population and the average annual rising rate (AARR) in the urban and rural areas was 6.31% and 0.38% respectively, while the ASMR had no obviously difference between the urban and rural populations (the AARR was 3.23% and 2.33% respectively); The ASIR of thyroid cancer was the highest in the eastern region with a markedly rising, but its ASMR had a relatively lower rising rate, while the ASIR in the western region was relatively lower and the ASMR also showed a downward trend, and the ASMR in the central region had a relatively obvious rising rate. ② The estimated incidence and mortality of thyroid cancer in China in 2022: the estimated ASIR and ASMR of the whole population in 2022 was still rising as compared with in 2018 (ASIR: 24.64 per 100 000 vs. 12.01 per 100 000; ASMR: 0.45 per 100 000 vs. 0.37 per 100 000 ); The estimated ASIR and ASMR in women were still much higher than in men (ASIR: 36.51 per 100 000 vs. 13.25 per 100 000; ASMR: 0.55 per 100 000 vs. 0.35 per 100 000); Among the urban and rural populations, the estimated ASIR in urban was still higher than in rural areas (27.87 per 100 000 vs. 17.66 per 100 000), while the estimated ASMR had no marked difference between them (0.41 per 100 000 vs. 0.52 per 100 000). Compared with 2018, the development trend of the ASIR was still rising (urban: 27.87 per 100 000 vs. 15.58 per 100 000; rural: 17.66 per 100 000 vs. 8.95 per 100 000). The age specific ASIR of thyroid cancer showed a marked sex differences, that is, it began to rise rapidly from the 20–30 years old group, and reached the peak at the 45–50 years old group (the highest ASIR was 97.00 per 100 000) in women; However, which had been in a slower upward trend from the 0 to 20 years old group, while it had been rising rapidly from the 20 to 25 years old group, reaching the peak at the 30–35 years old group (the highest ASIR was 31.60 per 100 000) in men. The overall trend of age specific ASMR for thyroid cancer was similar for both males and females, with a slower increase starting from the 0–35 years old age group and continuous rising till 85 years old and above. ConclusionsThe incidence and mortality of thyroid cancer in China are rising, and the disease burden is still severe and the differences are existed in urban and rural areas, sex, age, and main regions. Overall, the prevention and control situation is complex and severe in China.
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 comprehend the incidence of and to search for the possible risk factors for neonatal congenital heart disease (CHD) in Mianyang after "5·12" Earthquake. MethodsCHD screening was performed on 5536 neonates born between December 2011 and December 2012 by cardiac auscultation, respiration evaluation, blood oxygen saturation determination and color doppler flow imaging. Case control study was applied to study the diagnosed cases of CHD. ResultsSixty-five cases of CHD were found during the screening, and the incidence was 11.74‰. The most common CHD was ventricular septal defect, followed by atrial septum defect and patent ductusarteriosus. Possible risk factors were listed in order of their risks were as follows:family history of CHD, infection history in the early period of pregnancy, drug and alcohol history during pregnancy, and aged pregnancy and smoking history of the parents. However, earthquake experience history of parents was not correlated with CHD incidence. ConclusionEarthquake experience of parents is not correlated with CHD incidence. Enforcing health education for women before gestation, and avoiding or decreasing risk factors exposure can reduce the risk of CHD. CHD screening for neonates can detect CHD as early as possible, which is helpful for intervention during the follow-up, reduction of fatality, and improvement of neonates' quality of life.
In 2022, the National Cancer Center (NCC) of China reported the nationwide statistics of 2016 using population-based cancer registry data from all available cancer registries in China, which was mainly about the cancer incidence and mortality. Cancer remains a major health problem currently in our country and requires long term cooperation to deal with. This article provided a key point interpretation and analysis of cancer prevalence data in China, and provided an analysis of several main risk factors for cancer, which was conducive to the development of cancer prevention and control programs in different regions.
