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 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 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 systematically review the incidence and influencing factors of early enteral nutritional feeding interruptions in critically ill patients. MethodsThe PubMed, Web of Science, Embase, Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect observational studies on the early enteral nutritional feeding interruptions in critically ill patients from inception to January 2, 2024. 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 17.0 software. ResultsA total of 12 studies including 1 121 patients were included. Meta-analysis showed that the incidence of early enteral nutritional feeding interruptions in critically ill patients was 75.0% (95%CI 64.0% to 84.0%). Influenced by feeding intolerance, airway management, tube problems, radiological examination, and endoscopy, surgery and so on, interruptions of early enteral nutritional feeding frequently occur in critically ill patients. ConclusionCurrent evidence shows that early enteral feeding interruptions in critically ill patients are affected by many factors, and the incidence is high. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.
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.
ObjectivesTo systematically review the complications of knee arthroscopic surgeries in China.MethodsWe searched PubMed, EMbase, CNKI, WanFang Data and VIP databases to collect cross-sectional studies on the complications of knee arthroscopic surgeries in China from inception to March 1st, 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 36 studies involving 20 740 cases were included. The results of meta-analysis showed the incidence rate of complication in knee arthroscopic surgeries in China was 9.71% (95%CI 8.20% to 11.23%). Subgroup analysis showed that the complication incidence rates in the eastern, central and western regions were 10.04% (95%CI 8.00% to 12.14%), 9.67% (95%CI 6.57% to 12.76%) and 7.47% (95%CI 6.20% to 8.73%). The complication incidence rates in the upper first-class and non-upper first-class hospitals were 9.50% (95%CI 7.83% to 11.17%) and 10.95% (95%CI 6.75% to 15.14%). The top 3 complication types with highest incidence rate included joint effusion［2.16% (95%CI 1.44% to 2.87%)］, accidental injury of native structures［1.49% (95%CI 0.96% to 2.03%)］ and hemorrhage［1.43% (95%CI 1.01% to 1.84%)］. Other severe complications including neurovascular injury, thrombosis diseases and infection were 0.06% (95%CI 0.02% to 0.11%), 0.33% (95%CI 0.19% to 0.48%) and 0.08% (95%CI 0.03% to 0.13%).ConclusionsCurrent evidence shows that the complication incidence rate of arthroscopic surgeries in China is relatively high and the complication type is complex and varied. Due to the quantity and quality of the included studies, more high-quality studies are required to verify the above conclusions in future.
ObjectiveTo analyze the incidence and mortality trends of falls among elderly in China from 1990 to 2019, and to evaluate the impact of age, period, and cohort on their long-term trends. MethodsThe joinpoint regression model and age-period-cohort model were used to analysis. The annual percent change (APC) and the average annual percent change (AAPC) were used to analyze the incidence and mortality of falls among elderly in China from 1990 to 2019. The influence of age, period and cohort on the incidence and mortality of falls were analyzed. ResultsThe standardized incidence and mortality rates of falls among the elderly in China showed fluctuating upward trends from 1990 to 2019 (AAPC=1.929%, 1.535%, P<0.001), The increase rate of falls incidence was higher in men than that in women (AAPC=1.928%, 1.923%, P<0.001), and the increase rate of falls mortality was lower in men than that in women (AAPC=1.407%, 1.562%, P<0.001). The results of the age-period-cohort model showed that the age effect and period effect coefficients of incidence and mortality of falls in Chinese elderly men and women showed an overall fluctuating upward trend, while the cohort effect coefficients showed an overall downward trend. ConclusionFrom 1990 to 2019, the age standardized incidence and mortality rate of falls among the elderly in China show fluctuating upward trends. The incidence of falls in elderly women is higher than that in men, and the mortality rate of falls in elderly men is higher than that in women. It is recommended to strengthen the prevention work for falls in the oldest old, the incidence of falls in elderly women, and the mortality of falls in elderly men.
Objective To estimate the incidence of post-myocardial infarction depression among Chinese acute myocardial infarction (AMI) patients by meta-analysis and to provide references for the management of AMI patients. Methods We searched databases including PubMed, The Cochrane Library (Issue 6, 2016), CNKI, CBM, WanFang Data and VIP from January 2000 to July 2016, to collect literature regarding the incidence of post-myocardial infarction depression among patients with AMI. Two reviewers independently screened literature, extracted data and evaluated the methodological quality of the included studies. Then meta-analysis was performed by using Comprehensive Meta Analysis (CMA) 2.0 software. Results Totally, 22 cross-sectional studies were included, involving 2 986 AMI patients, of which1 239 were post-myocardial infarction depression patients. The overall incidence of post-myocardial infarction depression among the AMI patients was 42.7% (95%CI 36.3% to 49.4%). There was no statistical differences observed when the studies were stratified by sex, regions, scales and years (allP values>0.05). Conclusion In China, the incidence of post-myocardial infarction depression is high and rising year by year roughly among AMI patients. The status should be paid more attention.
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 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.
