Objective To understand the epidemiological characteristics of lung cancer death in adults of Zhuhai in order to provide decision-making evidence for lung cancer control and prevention. Methods The data of Mortality Registration System from 2004 to 2005 in Zhuhai were applied to analyze the epidemiological features of lung cancer death in adults. Results From 2004 to 2005, the average mortality from lung cancer and the standardized rate in adults of Zhuhai were 25.3/lakh and 30.3/lakh, respectively. Lung cancer ranked the first on the list of death causes in all cases of cancer death. The standardized rate of the male and female population was 40.1/lakh and 19.2/lakh, respectively. The standardized rate of males was higher than that of females (u=7.23, Plt;0.01). The average mortality from lung cancer increased with age, especially in males over 60 years old. The standardized mortality from lung caner in Xiangzhou, Doumen and Jinwan was 30.5/lakh, 31.1/lakh and 27.3/lakh, respectively. No statistical significance was found in these areas. Conclusion Lung cancer is one of the major malignant tumors among Zhuhai people. Lung cancer mortality is increasing with population aging. Based on the main risk factors of lung cancer, effective preventive measures including tobacco control and environment improvement should be taken.
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.
Heart valve disease is one of the three most common cardiac diseases,and the patients undergoing valve surgery have been increasing every year. Due to the high mortality,increasing number of valve surgeries,and increasing economic burdens on public health, a lot of risk models for valve surgery have been developed by various countries based on their own clinical data all over the world,which aimed to regulate the preoperative risk assessment and decrease the perioperative mortality. Over the last 10 years, a number of excellent risk models for valve surgery have finally been developed including the Society of Thoracic Surgeons(STS), the Society of Thoracic Surgeons’ National Cardiac Database (STS NCD),New York Cardiac Surgery Reporting System(NYCSRS),the European System for Cardiac Operative Risk Evaluation(EuroSCORE),the Northern New England Cardiovascular Disease Study Group(NNECDSG),the Veterans Affairs Continuous Improvement in Cardiac Surgery Study(VACICSP),Database of the Society of Cardiothoracic Surgeons of Great Britain and Ireland(SCTS), and the North West Quality Improvement Programme in Cardiac Interventions(NWQIP). In this article, we reviewed these risk models which had been developed based on the multicenter database from 1999 to 2009, and summarized these risk models in terms of the year of publication, database, valve categories, and significant risk predictors.
Objective To evaluate the effects and safety of procalcitonin(PCT)-guided algorithms of antibiotic therapy in critically ill patients in intensive care unit (ICU). Methods Literatures in English and Chinese concerning randomized controlled trials(RCTs) on PCT-guided algorithms of antibiotic therapy in critically ill patients was retrieved by electronic and manual search. All related data were extracted. Meta-analysis was conducted using the statistical software RevMan 5.3 on the basis of strict quality evaluation. Results Eight RCTs involving 2708 ICU patients were included, with 1360 patients in the PCT-guided group and 1348 patients in the control group. Compared with the control group, PCT-guided algorithms were associated with a significant reduction in the duration of antibiotic therapy (MD -2.44 days, 95%CI -3.25 to -1.62, P < 0.00001), and the occurrence of adverse reaction of antibiotics was also lower (RR=0.74, 95%CI 0.56 to 0.97, P=0.03), however the mortality exhibited no difference between the PCT-guided group and the control group (RR=1.00, 95%CI 0.89 to 1.13, P=0.99). Conclusion PCT-guided algorithms can shorten the duration of antibiotic therapy and reduce the occurrence of adverse reaction in critically ill patients without significant effect on mortality.
Objective To validate the accuracy of the colorectal cancer model of the Association of Coloproctology of Great Britain and Ireland (ACPGBI-CCM), and to find out the relationship between clinical risk factors and the predictive value produced by ACPGBI-CCM. Methods The patients diagnosed definitely as colorectal cancer in the department of anal-colorectal surgery, West China hospital from April 2007 to July 2007 were analyzed retrospectively. And the predictive value of mortality for each patient was calculated by ACPGBI-CCM, then the difference of risk factors was compared by classifying the patients into lower risk group and higher risk group by making the median predictive mortality as a cut point. Results From April 2007 to July 2007, a total of 99 patients diagnosed definitely as colorectal cancer accepted treatment, and among which 67 patients included in this study were admitted whose average age was 60.09 years. And there were 34 male and 33 female patients; 15 right hemicolon cancer, 9 left hemicolon cancer, 43 rectal cancer; Dukes staging: A 0 case, B 37 cases, C 24 cases, D 6 cases. The observed mortality 30 days after operation was 0, whereas the predictive mortality was 0.77%-25.75% with a median value of 3.36%. Then the patients whose predictive mortality were ≤3.36% were grouped as lower risk group (34 cases), the others higher risk group (33 cases), and there was strikingly different predictive mortality between two groups 〔(8.86±4.51)% vs (1.76±0.68)%, P＜0.01〕. And between two groups, the age, internal medicine complications, preoperative chemotherapy, ASA grading, cancer resected, and operative time made predominant differences (P＜0.01); and the neoplastic complications, Dukes staging, TNM classification, postoperative pain showed differences, too (P＜0.05); however, the gender, history of abdominal operation, the distance of the neoplasm to anal edge, the cancer location, differentiated degree, postoperative hospitalization time, and total hospitalization time didn’t have any differences (Pgt;0.05). Furthermore, stratification analysis was made for risk factors, and it came out that there were great differences of predictive mortality for different age groups and ASA grading, having internal medicine complications or not, having chemotherapy or not, and for cancer resected or not, and the differences were statistically significant (P＜0.01); also different Dukes staging or differentiation could cause different mortality (P＜0.05); but the difference of mortality didn’t make any sense according to gender, having abdominal operative history or not, having neoplastic complications or not, different TNM staging and cancer location (Pgt;0.05). Conclusion The clinical applicability of the ACPGBI-CCM is ascertained in such a large volume single medical centre, but the ACPGBI-CCM overpredicts the mortality in this study which may be attributed to the different areas, nations, or the different cultures. The complications and the neo-adjuvant or adjuvant therapy are further found out that they may be independent predictive factors of survival, and more research will be needed to prove this.
Abstract： Objective To analyze risk factors for perioperative mortality in the arterial switch operation (ASO), in order to provide better operation and decrease the mortality rate. Methods We enrolled 208 ASO patients including 157 males and 51 females at Fu Wai Hospital between January 1, 2001 and December 31, 2007. The age ranged from 6 h to 17 years with the median age of 90 d and the weight ranged from 3 kg to 43 kg with the median weight of 5 kg. Among the patients, 127 had transposition of great artery (TGA) with ventricular septal defect (VSD), and 81 patients had TGA with intact ventricular septum (IVS) or with the diameter of VSD smaller than 5 mm. Coronary anatomy was normal (1LCX2R) in 151 patients and abnormal in the rest including 15 patients with single coronary artery, 6 with intramural and 36 with inverse coronary artery. Preoperative, perioperative and postoperative clinical data of all patients were collected to establish a database which was then analyzed by univariate analysis and multivariate logistic regression analysis to find out the risk factors formortality in ASO. Results There were 24 perioperative deaths (11.54%) in which 12 died of postoperative infection with multiple organ failure (MOF), 10 died of low cardiac output syndrome, 1 died of pulmonary hypertension, and 1 died of cerebral complications. Among them, 20 patients (18.30%) died in early years from 2001 to 2005, while only 4 (4.00%) died in the time period from 2006 to 2007, which was a significant decrease compared with the former period (Plt;0.05). The univariate analysis revealed that cardiopulmonary bypass (CPB) time was significantly longer in the death group than in the survival group（236±93 min vs. 198±50 min, P=0.002）, and occurrence of major coronary events (33.3% vs. 2.2%, P=0.000) and unusual coronary artery patterns（33.3% vs. 6.5%,P=0.000） were much more in the death group than in the survival group. Multivariate logistic regression analysis showed that early year of [CM(159mm]operation (OR=7.463, P=0.003), unusual coronary artery patterns (OR=6.303,P=0.005) and occurrence of majorcoronary events (OR=17.312, P=0.000) were independent predictors for perioperative mortality. Conclusion The ASO can be performed with low perioperative mortality in our hospital currently. Occurrence of major coronary events, unusual coronary artery patterns and year of surgery before 2006 are independent predictors for perioperative mortality.
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 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.
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 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.
