ObjectiveTo evaluate the prognosis factors for early death (within 60 days) of acute myocardial infarction (AMI) patients for early identification and prevention of the disease. MethodsWe analyzed the information of AML patients who were admitted to the emergency department between May 2009 and July 2010, and analyzed their clinical data, such as gender, age, prehospital time, myocardial enzyme, electrocardiogram, complications, whether the patients had thrombolysis therapy, time of thrombolysis, end point observation and time of death, ect. Cox multivariate survival analysis was performed with the use of SPSS 18.0 software. ResultsSeventy-one cases were collected with one of them excluded for fragmented data. After analysing, we found that patients' age and isoenzymes of creatine kinase (CK-MB) level were prognosis factors for early death. Further analysis showed that the relative risk (RR) of age was 1.166 (P=0.023), and the RR of CK-MB was 1.001 (P=0.004). ConclusionPatients' age has predictive value for early death of AML. More attention should be paid to AML patients with advanced age. Detecting myocardial enzymes levels, especially the CK-MB level, is significant for predicting early death. Other indicators need to be further explored due to the possible limitation of our study.
ObjectiveTo systematically review the association of body mass index (BMI) and mortality in chronic heart failure (CHF) pationts.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect cohort studies about the association of BMI and mortality in CHF patients from inception to June, 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 20 cohort studies involving 91 572 CHF patients were included. The results of meta-analysis showed that, compared to patients with normal weight, underweight individuals were associated with higher mortality (HR=1.48, 95%CI 1.36 to 1.62, P<0.001), whereas overweight (HR=0.86, 95%CI 0.78 to 0.94, P=0.002) and obese (HR=0.78, 95%CI 0.68 to 0.90, P=0.001) patients were associated with lower mortality.ConclusionCurrent evidence shows that underweight is associated with a higher risk of all-cause mortality among patients with CHF, whereas overweight and obese are associated with lower risk of all-cause mortality. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
ObjectiveTo analyze the trend of disease burden changes in congenital birth defects in China from 1990 to 2019. MethodsUsing the global burden of disease study 2019 (GBD 2019), we analyzed the morbidity, mortality, and disability-adjusted life years (DALYs) of congenital birth defect diseases and their corresponding age-standardized rates and average annual percentage change (AAPC) to analyze the changes in the disease burden of congenital birth defects in China and compared them with global data from 1990 to 2019. ResultsIn 2019, the age-standardized incidence, mortality, and DALY in China were 147.41/100 000, 4.62/100 000, 480.95/100 000, respectively. Compared with 1990, the age-standardized incidence rate, age-standardized mortality rate, and age-standardized DALY rate increased by 12.08% and decreased by 70.38% and 66.82%, respectively. In recent years, although the age-standardized incidence of congenital birth defect disease in China is on the rise and higher than the global level, the disease burden is roughly on the decline and lower than the global level, which is closely related to earlier intervention and treatment of the disease resulting in a lower standardized mortality rate. ConclusionThe age-standardized mortality rate of children with congenital birth defects in China showed a decreasing trend from 1990 to 2019, and the burden of disease ranged from slightly higher than global to lower than global levels, but the age-standardized incidence rate was significantly higher, but the age-specific incidence rate has increased significantly.
Objective To explore the perioperative management of the coexisting diseases for the elderly patients with gastric cancer. Methods The clinical data of perioperative management for coexisting diseases in 528 patients with gastric cancer over 70 years old treated in the First Affiliated Hospital of China Medical University from March 1980 to November 2008 were analyzed retrospectively. Results The main coexisting diseases included cardiovascuclar disease (259 cases, 49.05%), respiratory disease (161 cases, 30.49%), diabetes (72 cases, 13.64%). Adjusting blood pressure and blood glucose, improving cardiopulmonary function, and hepatic and renal function were mainly given. The common postoperative complications included intestinal obstruction (10 cases), pneumonia (10 cases), reflux esophagitis (9 cases), functional evacuation disorder of gastric remnant (7 cases), and anastomotic leakage (5 cases). Ten patients died during perioperative period: 6 died of heart and lung failure, 2 of acute myocardial infarction, 1 of anastomotic leakage, 1 of intestinal obstruction. Conclusions The common coexisting diseases in the elderly patients with gastric cancer are hypertension， bronchitis and diabetes. Complete assessment of the patient’s general health before operation and intensive perioperative management of the coexisting diseases not only can decrease the risk of surgical procedures， but also decrease the incidence of complication and perioperative mortality.
Objective To analyze the epidemic trend of prostate cancer in China from 1992 to 2021, and predict its epidemic trends from 2022 to 2032. Methods Based on the data of Chinese population and prostate cancer incidence and mortality from Global Burden of Disease Database, the Joinpoint log-linear model was used to analyze the trends of prostate cancer incidence and mortality, use the age-period-cohort model to analyze the effects of age, period and cohort on changes in incidence and mortality, and the gray prediction model was used to predict the trends of prostate cancer. Results From 1992 to 2021, the incidence and mortality of prostate cancer in China showed an upward trend, with AAPC of 5.652% (P<0.001) and 3.466% (P<0.001), and the AAPC of age-standardized incidence decreased to 1.990% (P<0.001), the age-standardized mortality showed a downward trend and was not statistically significant. The results of the age-period-cohort model showed that the net drift values of prostate cancer incidence and mortality were 3.03% and ?1.06%, respectively, and the risk of incidence and mortality gradually increased with age and period. The results of the grey prediction model showed that the incidence and mortality of prostate cancer showed an upward trend from 2022 to 2032, and the incidence trend was more obvious. Conclusion The incidence and mortality of prostate cancer in China showed an increasing trend, with a heavy disease burden and severe forms of prevention and control, so it is necessary to do a good job in monitoring the incidence and mortality of prostate cancer, and strengthen the efficient screening, early diagnosis and treatment of prostate cancer.
Abstract: Objective To explore the inhospital mortalityrelated risk factors in the patients undergoing offpump coronary artery bypass grafting (OPCAB). Methods We retrospectively analyzed the clinical data of 215 patients undergoing OPCAB in our hospital from November 2007 to November 2008. There were 171 males and 44 females aged between 40 and 85 years old. Among them, there were 47 patients older than 70 years old. All of them were coronary artery disease (CAD) patients with triple vessel disease. We adopted univarialble analysis and logistic multivariable regression analysis to screen the risk factors for the mortality of OPCAB. Results Six patients died in hospital after OPCAB with a mortality rate of 2.79% (6/215). No renal dysfunction or respiratory failure occurred. The rate of reoperation for bleeding was 4.65% (10/215) and all the 10 patients having undergone reoperation were alive. A total of 209 patients were all alive after 1year follow-up. The results of logistic multivariable regression analysis showed that New York Heart Association (NYHA) Ⅲ and Ⅳ heart function (OR=42.116，95% CI 3.319 to 534.465，P=0.004) and mechanical ventilation duration (OR=1.007，95%CI 1.001 to 1.013，P=0.028) were independent risk factors for inhospital mortality of OPCAB. Conclusion OPCAB is an effective and safe treatment for CAD with triple vessel disease. NYHA Ⅲ and Ⅳ heart function and mechanical ventilation time after OPCAB are the risk factors for OPCAB inhospital mortality, yet, needs further study with large sample.
ObjectiveTo compare the outcomes of local anesthesia and general anesthesia in transcatheter aortic valve replacement (TAVR).MethodsA total of 399 severe aortic stenosis patients were included, who underwent TAVR successfully in West China Hospital of Sichuan University between April 2012 and January 2019. The baseline characteristics, procedural details, postprocedural outcomes, and ultrasound data of those patients were collected. All patients were followed up and the end date of follow-up was June 20th 2020. According to anesthetic mode, the patients were divided into local anesthesia group and general anesthesia group. The differences between the two groups in incidence of postprocedural complications, hemodynamics, postprocedural 30-day mortality, and postprocedural 1-year mortality were retrospectively analyzed.ResultsOf the 399 patients, 206 (51.6%) received local anesthesia and 193 (48.4%) received general anesthesia. There was no statistical difference between the two groups in baseline characteristics. The symptoms of both groups were relieved. But the incidences of mild bleeding events (12.4% vs. 1.5%, P<0.001), severe bleeding events (10.4% vs. 0.5%, P<0.001), major vascular complications (0.5% vs. 3.6%, P=0.032), and postprocedural 30-day all causes mortality (1.9% vs. 6.7%, P=0.018) were significantly lower in the local anesthesia group than those in the general anesthesia group.ConclusionIn TAVR, compared with general anesthesia, local anesthesia is safer to use with lower incidence of postprocedural complications and postprocedural 30-day all causes mortality.
ObjectivesTo explore a reliable and simple predictive tool for 30-day mortality of influenza A community-acquired pneumonia (CAP).MethodsA multicenter retrospective study was conducted on 178 patients hospitalized with influenza A CAP, including 144 alive patients and 34 dead patients. Receiver operating characteristic (ROC) curves were performed to verify the accuracy of severity scores as 30-day mortality predictors in the study patients.ResultsThe 30-day mortality of influenza A CAP was 19.1%. The actual mortality of PSI risk class Ⅰ-Ⅱ and CURB-65 score 0-1 were 14.5% and 15.7%, respectively, which were much higher than the predicted mortality. Logistic regression confirmed blood urea nitrogen >7 mmol/L (U), albumin <35 g/L (A) and peripheral blood lymphocyte count <0.7×10 9/L (L) were independent risk factors for 30-day mortality of influenza A CAP. The area under the ROC curve (AUC) of UAL (blood urea nitrogen >7 mmol/L+ albumin <35 g/L+ peripheral blood lymphocyte count <0.7×10 9/L) was 0.891, which was higher than CURB-65 score (AUC=0.777, P=0.008 3), CRB-65 score (AUC=0.590, P<0.000 1), and PSI risk class (AUC=0.568,P=0.000 1).ConclusionUAL is a reliable and simple predictive tool for 30-day mortality of influenza A CAP.
Objective To analyze the characteristic and temporal trend in mortality and disease burden of Alzheimer’s disease (AD) and other forms of dementia in Guangzhou from 2008 to 2019, and estimate the disease burden attributable to smoking to provide evidence for promoting local health policy of prevention and intervention of dementia. Methods Based on the data of Guangzhou surveillance point of the National Mortality Surveillance System (NMSS), the crude mortality, standardized mortality, years of life lost (YLL) of AD and other dementia were calculated. The indirect method was used to estimate years lived with disability (YLD) and disability-adjusted life years (DALY).The distribution and changing trends of the index rates were compared from 2008 to 2019 using Joinpoint Regression Program. Based on the data of Guangzhou Chronic Disease and Risk Factors Monitoring System in 2013, the indexes of disease burden of AD and other forms of dementia attributable to smoking in 2018 was calculated. Results The standardized mortality rate, YLL rate, YLD rate and DALY rate of AD and other forms of dementia in Guangzhou increased from 0.45/100 000, 0.05‰, 0.02‰ and 0.07 ‰ in 2008 to 1.28/100 000, 0.15‰, 0.07‰ and 0.22‰ in 2019, respectively. The average annual changing trend was statistically significant (AAPC=11.30%, 13.09%, 13.09%, 13.09%, P<0.001）. In most years, the mortality and disease burden of women were higher than those of men, but men had higher growing trend than women in standardized mortality rate, YLL rate, YLD rate and DALY rate from 2008 to 2019, with a slower growing speed after the year 2012.The disease burden of dementia attributable to smoking in men was significantly higher than that in women. Conclusion The mortality and disease burden of AD and other forms of dementia in Guangzhou have dramatically increased over the past twelve years. Intervention against modifiable factors such as smoking, and prevention and screening for dementia in key populations should be strengthened. Support policies for dementia care management should be adopted to reduce the disease burden caused by premature death and disability.
ObjectiveTo analyze the causes of death of patients with asthma-chronic obstructive pulmonary disease overlap syndrome (ACOS). MethodsA total of 493 patients admitted between January 2006 and Octomber 2015 were respectively analyzed, including 348 asthma patients and 145 ACOS patients. The patients was divided into a survival group and a death group based on the outcome. The ACOS patients were divided into three subgroups based on FEV1% pred level (≥80%, 50%-80%, and < 50%, respectively). The basic characteristics and causes of death were analyzed using χ2-test, t-test and Fish-test based on data type. ResultsThe age (t=3.457, P < 0.001), male proportion (χ2=15.394, P < 0.001) and smoking history (χ2=12.418, P=0.002) had significant differences between the survival group and the death group. The proportion of ACOS patients was higher in the death group (42% vs. 27%, χ2=7.033, P=0.008), and the mortality was also higher in the ACOS patients (21% vs. 12%). The proportion of male patients was higher in the ACOS patients than that in the asthma patients (86% vs. 38%, P < 0.001). The leading three causes of death in the ACOS patients were malignant diseases (45%), pneumonia (26%), and cardiovascular diseases (16%). Malignant diseases were the main cause of death in the ACOS patients with FEV1% pred≥50%, while pneumonia was the main cause of death in those with FEV1% pred≥50%. There was no significant difference in cause of death distribution between three subgroups with different FEV1% pred (P=0.318). ConclusionThe main cause of death of ACOS patients is malignant diseases, the followed are pneumonia and cardiovascular diseases.
