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.
ObjectivesTo systematically review the association between body mass index (BMI) and mortality of chronic obstructive pulmonary disease (COPD).MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect cohort studies on the association between BMI and mortality of COPD from inception to February, 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 14 cohort studies involving 494 060 COPD patients were included. The results of meta-analysis showed that, compared with patients having a normal weight, underweight individuals were associated with higher mortality (RR=1.40, 95%CI 1.15 to 1.71, P=0.000 8), whereas overweight (RR=0.65, 95%CI 0.54 to 0.79, P<0.000 1) and obese (RR=0.37, 95%CI 0.20 to 0.67, P=0.001) patients were associated with lower mortality.ConclusionsCurrent evidence shows that underweight is associated with a higher risk of all-cause mortality among patients with COPD, whereas overweight and obese are associated with lower risk of all-cause mortality in these patients. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
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 outcome of arterial switch operation （ASO） for surgical repair of complete transposition of the great arteries （TGA）, and to investigate the risk factors influencing the mortality of ASO. Methods The clinical data of patients suffered from TGA and treated with ASO from the January 2003 to December 2004, and the clinical records in hospital including eehoeardiogram and operation record were collected. The clinical data were analyzed by chi-squared test and logistic muhivariable regression analysis, including the age undergone operation, body weight, diagnosis, anatomic type of coronary artery, cardiopulmonary bypass time, aortic crossclamping time, circulation arrest time, assisted respiration time after operation, the delayed closure of sternum and so on. The risk factors influencing the early mortality of the ASO were analyzed. Results Sixty seven patients were operated with ASO, five patients died during the peri-operative period. The outcome of univariate analysis indicated that risk factors influencing the mortality of ASO included： age（P=0. 004）, body weight （P=0. 042）, anatomic type of coronary artery （P= 0. 006） and extracorporeal circulation time （P= 0. 048）, the length of the CICU stay（P= 0. 004） and the hospital stay（P=0. 007） after operation in the TGA/VSD patients were longer than those in TGA/ IVS patients. The logistic muhivariable regression analysis indicated that the age at operation （P= 0. 012）, coronary arteries anomaly （P = 0.001 ）and the longer cardiopulmonary bypass time （P = 0. 002） were correlated with the increase of death rate. Conclusion It could be good results for TGA patients who was repaired with ASO. The age at operation, the coronary arteries anomaly and the longer cardiopulmonary bypass time are the risk factors influencing the mortality.
ObjectiveTo systematically review mortality risk prediction models for acute type A aortic dissection (AAAD). MethodsPubMed, EMbase, Web of Science, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect studies of mortality risk prediction models for AAAD from inception to July 31th, 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Systematic review was then performed. ResultsA total of 19 studies were included, of which 15 developed prediction models. The performance of prediction models varied substantially (AUC were 0.56 to 0.92). Only 6 studies reported calibration statistics, and all models had high risk of bias. ConclusionsCurrent prediction models for mortality and prognosis of AAAD patients are suboptimal, and the performance of the models varies significantly. It is still essential to establish novel prediction models based on more comprehensive and accurate statistical methods, and to conduct internal and a large number of external validations.
Objective To analyze the causes of injury-related deaths of permanent residents in Zigong city, so as to provide scientific references for the prevention and control of injury deaths and for putting forward to relevant health policies as well. Methods Based on the death surveillance data of Zigong from 2001 to 2009, following indicators were analyzed, such as cause specific mortality, age specific mortality and potential years of life lost (PYLL). Results An accumulative total of 10 957 people died of injury from 2001 to 2009, and the crude mortality was 38.13/100 thousands, while the standardized mortality was 36.07/100 thousands. The highest mortality was at the age of more than 65 years of age. The first six injury death causes were as follows: drowning, transport accidents except motor vehicle, suicide, motor vehicle accidents, accidental falling and accidental poisoning. The PYLL of injury death was 334 325.50 person year, APYLL was 34.67 year, and the PYLL rate was 11.63‰ which was higher in male than that of female. Conclusion The epidemiological analysis of injury-related deaths shows an ascending trend, which is the main reason resulting in the loss of residents’ life. Injury has become one of the most serious problems of public health, and it should be prevented and controlled by formulating effective measures and strategies aiming at the injury death spectrum and the target population of Zigong city.
Objectives To assess the relationship between subclinical hyperthyroidism and the incidence of coronary heart disease (CHD). Methods PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, VIP, WanFang Data and CBM databases were searched for studies on the relationship between subclinical hyperthyroidism and the incidence of CHD from inception to October 2016. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 and Stata 12.0 software. Results In total, 14 cohort studies were included. The results of meta-analysis showed that subclinical hyperthyroidism was associated with the incidence of coronary heart disease (RR=1.19, 95%CI 1.01 to 1.40, P=0.04) and all-cause mortality (RR=1.36, 95%CI 1.11 to 1.67, P=0.003). Conclusions Subclinical hyperthyroidism is associated with an increased risk of CHD and all-cause mortality. Due to the limitation of quality and quantity of the studies, the above conclusions are required to be verified by large-scale and high quality research.
ObjectiveTo assess the accuracy of European System for Cardiac Operative Risk Evaluation (EuroSCORE) model in predicting the in-hospital mortality of Uyghur patients and Han nationality patients undergoing heart valve surgery. MethodsClinical data of 361 consecutive patients who underwent heart valve surgery at our center from September 2012 to December 2013 were collected, including 209 Uyghur patients and 152 Han nationality patients. According to the score for additive and logistic EuroSCORE models, the patients were divided into 3 subgroups including a low risk subgroup, a moderate risk subgroup, and a high risk subgroup. The actual and predicted mortality of each risk subgroup were studied and compared. Calibration of the EuroSCORE model was assessed by the test of goodness of fit, discrimination was tested by calculating the area under the receiver operating characteristic (ROC) curve. ResultsThe actual mortality was 8.03% for overall patients, 6.70% for Uyghur patients,and 9.87% for Han nationality patients. The predicted mortality by additive EuroSCORE and logistic EuroSCORE for Uyghur patients were 4.03% and 3.37%,for Han nationality patients were 4.43% and 3.77%, significantly lower than actual mortality (P<0.01). The area under the ROC curve of additive EuroSCORE and logistic EuroSCORE for overall patients were 0.606 and 0.598, for Han nationality patients were 0.574 and 0.553,and for Uyghur patients were 0.609 and 0.610. ConclusionThe additive and logistic EuroSCORE are unable to predict the in-hospital mortality accurately for Uyghur and Han nationality patients undergoing heart valve surgery. Clinical use of these model should be considered cautiously.
ObjectiveTo systematically review the efficacy of promoting neonatal resuscitation technique in treatment of neonatal asphyxia in China. MethodsElectronical databases including WanFang Data, CNKI, VIP, Jiangsu Engineering and Technology Literature Information Center, PubMed and The Cochrane Library (Issue 5, 2016) were searched to collect studies of neonatal resuscitation technique in treatment of neonatal asphyxia up to June 1st, 2016. Two reviewers independently screened literature, extracted data and assessed the risk bias of included studies, and then meta-analysis was performed by using RevMan 5.2 software. ResultsA total of eighteen observational studies were included, involving 28 144 cases of neonatal asphyxia and 32 636 cases of control, 2 148 death cases of neonatal asphyxia and 1 679 cases of controls. The results of meta-analysis showed that neonatal resuscitation technique could reduce newborn suffocation rate compared with the control group in hospital surveys (RR=0.59, 95%CI 0.55 to 0.63, P<0.000 01) and in regional project surveys (RR=0.72, 95%CI 0.69 to 0.75, P<0.000 01). Neonatal resuscitation could also reduce neonatal asphyxia mortality rate in hospital surveys (RR=0.26, 95%CI 0.16 to 0.42, P<0.000 01) and in regional surveys (RR=0.65, 95%CI 0.55 to 0.77, P<0.000 01). ConclusionThe existing evidence shows that neonatal resuscitation technology could effectively reduce the incidence of neonatal asphyxia and mortality rate in China. Due to the limitations of the quantity and quality of present studies, we need to carry out prospective multicenter cohort studies to verify the current results.
Objective To investigate clinical outcomes and perioperative management of off-pump coronary artery bypass grafting （OPCAB） for patients following acute myocardial infarction （AMI）.?Methods?From January 2006 to March 2010， 239 consecutive patients underwent OPCAB on the 14-27 （20.55±3.91） d following AMI（AMI group）in Renji Hospital，School of Medicine of Shanghai Jiaotong University. Preoperative MB isoenzyme of creatine kinase（CK-MB） level was （15.82±6.24） U/L and cardiac troponin I（cTnI） was （0.07±0.04） ng/ml. Clinical data of 406 patients without myocardial infarction history who underwent OPCAB during the same period were also collected as the control group for comparison.?Results?The 30-day mortality of AMI group was 2.51% （6/239）. The causes of death were circulatory failure in 4 patients， ischemic necrosis of lower extremity caused by intra-aortic balloon pump （IABP） in 1 patient and pneumonia with septic shock in 1 patient. Dopamine usage in AMI group was significantly higher than that of the control group （61.51% vs. 37.44%， P=0.001）. Intraoperative or postoperative IABP implantation was more common in AMI group， but there was no statistical difference between the two groups（P＞0.05） . Postoperative drainage and blood transfusion in AMI group were significantly larger than those of the control group （385.18±93.22 ml vs. 316.41±70.05 ml， P=0.022；373.68±69.54 ml vs. 289.78±43.33 ml， P=0.005， respectively）. But there was no statistical difference in re-exploration rate between the two groups （P＞0.05）. There was no statistical difference in the incidence of postoperative new onset atrial fibrillation between the two groups （P＞0.05）. Incidence of acute kidneyinjury of AMI group was significantly higher than that of the control group （13.81% vs. 8.62%， P=0.038）. Postoperative 30-day mortality of AMI group was higher than that of the control group， but there was no statistical difference between the two groups （2.51% vs. 1.48%，P＞0.05）. There was no statistical difference in ICU stay time and postoperative hospital stay between the two groups （2.01±0.95 d vs. 1.78±0.98 d；10.33±4.16 d vs. 9.89±4.52 d， respectively， P＞0.05）. A total of 211 patients （88.28%）in AMI group were followed up for 2.89±1.02 years， and 28 patients （11.72%） were lost during follow-up. Twenty-five patients died during follow-up including 14 cardiac deaths. One-year survival rate was 97.63%， and five-year survival rate was 88.15%.?Conclusion?It’s comparatively safe to perform OPCAB for patients at 2-4 weeks following AMI when their CK-MB and cTnI levels have returned to normal range.
