ObjectiveTo systematically review the associations of cognitive frailty with mortality and hospitalization in the elderly. MethodsThe VIP, PubMed, CNKI, WanFang Data, CBM, Embase, Cochrane Library and Web of Science databases were electronically searched to collect cohort studies on the association of cognitive frailty with mortality or hospitalization in the elderly from inception to May, 2023. Two reviewers independently screened the literature, extracted data and assessed risk of bias of the included studies. Meta-analysis was performed by R 4.2.2 software. ResultsA total of 19 cohort studies involving 63 624 elderly were included. The results of meta-analysis showed that compared with healthy elder, the elder with cognitive frailty had a higher mortality (OR=2.75, 95%CI 2.10 to 3.59, P<0.01) and hospitalization (OR=1.67, 95%CI 1.40 to 2.00, P<0.01). Subgroup analysis showed that cognitive frailty was related to the risk of death in different status of frailty and cognitive function, different assessment tools, different countries of development, different follow-up time and research sites. At the same time, different status of frailty and cognitive function and different levels of development of countries were related to the risk of hospitalization. ConclusionCurrent evidence shows that cognitive frailty can increase the risk of hospitalization and mortality in the elderly. It is suggested that early screening and intervention of cognitive frailty should be carried out to effectively reduce the risk of adverse consequences, so as to achieve healthy aging.
Objective We investigated the effect of supplementation with alanyl-glutamine dipeptide on insulin resistance and outcome in patients with chronic obstructive pulmonary disease (COPD) and respiratory failure. Methods A prospective, randomized, open and controlled trial was conducted. Patients with COPD and respiratory failure were recruited between Jan 2005 to Feb 2006 and randomly assigned to a trial group (n=14) with glutamine dipeptide supplmented parenteral nutrition and a control group (n=16) with isocaloric, isonitrogenic parenteral nutrition. On the third day and fifth day of nutrition treatment, blood glucose was clamped at level of 4.4 to 6.1 mmol/L by intravenously bumped insulin. Blood gas, blood glucose level, insulin dosage were recorded everyday. The outcomes were mortality, length of stay (LOS) in hospital and in ICU, mechanical ventilation times and the costs of ICU and hospital.Results Thirty patients successfully completed the trial. There was no difference in blood gas between two groups, but PaO2 increased gradually. Compared with control group, blood glucose level had trend to decrease in trial group. The average insul in consumption decreased significantly in trial group on the fifth day. There was no statistical difference between two groups in mortality, length of stay in hospital and the costs of hospital. But compared with control group, length of stay in ICU and mechanical ventilation days had trend to decrease in trial group. Conclusion Alanyl-glutamine dipeptide do not improve pulmonary function of patients with COPD and respiratory failure. However, alanyl-glutamine dipeptide attenuated insul in resistance and stabilized blood glucose. This trial does not confirm alanyl-glutamine di peptide can improve outcome in critically ill patients with COPD and respiratory failure between two groups in mortality at the end of 30 days, length of stay in hospital and the costs of hospital. But the length of stay in ICU and the duration of mechanical ventilation does decrease, but not significantly, in the trial group.
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.
Objective To analyse postoperative complications and cause of death for carcinoma of esophagus. Methods A retrospective study was undertaken for data of 2 085 patients with esophageal carcinoma from 1963 to 2003, the patients were divided into group A (332 cases,1963-1983), group B(727 cases,1984-1993) and group C (1 026 cases,1994-2003) by time. The postoperative complications and cause of death were analysed. Results Resectability rate, incidence rate of postoperative complications and hospital mortality were 90.84%(1 894/2 085), 11.61% (242/2 085) and 1.82% (38/2 085) respectively. Main complications were pulmonary complications (3.93%,82/2 085),anastomotic leak (3.12%,59/1 894), and cardiovascular disease (1.29%,27/2 085). Resectability rate of group B and group C were higher than that of group A, incidence rate of postoperative complications and hospital mortality of group B and group C were lower than that of group A. Resectability rate of group C were higher than that of group B, incidence rate of postoperative complications except pulmonary complications and hospital mortality of group C were lower than those of group B. Conclusions Pulmonary complications and anastomotic leak are main postoperative complications and cause of hospital death for carcinoma of esophagus, they are decreasing in recent years because of the progress of anesthetic,surgical technique and perioperative management.
Abstract: Objective To summarize the experience of combined coronary artery bypass grafting(CABG) and valve replacement. Methods From May 1997 to March 2006, the results of 80 consecutive patients undergone valve replacement (MVR) and CABG were analyzed. CABG were performed withtotal grafts in 159 grafts (mean 1.99 grafts), with mitral valve replacement (MVR) in 49 patients, with aortic valve replacement (AVR) in 18 patients, with MVR+AVR in 13 patients(mechanical valve replacement in 68 and biological valve replacement in 12). Results The hospital time after operation was 19.2±13.4d. The hospital mortality rate was 12.5% (10/80). The primary cause of death included low cardiac output yndrome, acute renal failure, nervous system complications ,ventricular fibrillation and cardiac arrest. Multivariate testing of preoperative and operative description identified that preoperative myocardial infarction, worse cardiac function, radiographic cardiac enlargement and low ejection fraction were associated with an increase of hospital mortality (P＜0.05). There were postoperative complications including bleeding, severe ventricular arrhythmia, nervous system complications and incision infection. Followup of 58 patients (82.86%, range 6 to 60 months) showed the symptoms of angina pectoris and heart failure were significantly relieved. There were 2 longterm deaths (cerebral infarction and lung infection). Conclusion Combined CABG and valve replacement is an effective way for treatment of coronary artery and valvular heart disease. Improving the heart function preoperatively, strengthening myocardial protection, shortening operation and myocardial ischemia time, and complete revascularization are the key factors for success operation.
Abstract： Objective To explore the impact of obesity on postoperative morbidity and mortality after pneumonectomy. Methods Clinical data of 3 494 patients with pulmonary diseases who underwent pneumonectomy in Shanghai Pulmonary Hospital from September 2003 to December 2007 were retrospectively analyzed. All the 3 494 patients were divided into two groups according to the patients’ preoperative body mass index （BMI）. There were 3 340 patients in the non-obesity group （BMI＜28 kg/m2） including 2 502 males and 838 females with their average age of 61.9±10.7 years， and 154 patients in the obesity group （BMI≥28 kg/m2） including 87 males and 67 females with their average age of 59.7±9.6 years. Univariate analysis and logistic regression were used to analyze the impact of obesity （BMI≥28 kg/m2） on postoperative morbidity after pneumonectomy. Results There were a total of 26 cases of perioperative death， including 23 patients in the non-obesity group and 3 patients in the obesity group. There was no statistical difference in mortality between the two groups ［0.7% （23/3 340） vs. 1.9% （3/154）， P=0.118］. There was no statistical difference in any particular postoperative morbidity or incidence of pulmonary complications between the two groups （P＞0.05）. Other than pulmonary complications， the incidence of postoperative complication in other body systems of the obesity group was significant higher than that of the non-obesity group （P＜0.05）. The incidence of cerebrovascular accidents， myocardial infarction and acute renal failure of the obesity group was significant higher than those of the non-obesity group （P＜0.05）. Logistic regression showed that obesity （BMI≥28 kg/m2） was not an independent risk factor for postoperative morbidity after pneumonectomy ［B=0.648， OR=1.911， 95% CI（0.711， 5.138），P=0.199］. Conclusion Obesity is not a significant risk factor of postoperative mortality or morbidity after pneumonectomy.
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.
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.
ObjectiveTo analyze the trend of disease burden of colorectal cancer (CRC) in China from 1990 to 2019.MethodsData was obtained from Global Burden of Disease Study 2019 (GBD 2019). Incidence, mortality, disability-adjusted life year (DALY), years of life lost (YLL), years lived with disability (YLD), and their corresponding standardized rate and annual average percentage change (AAPC) were used to describe the changes of disease burden of colorectal cancer in Chinese population between 1990 and 2019.ResultsCompared with 1990, the number of new cases, standardized incidence, the number of deaths and standardized mortality of CRC in China in 2019 increased by 474.03%, 144.01%, 230.14%, and 36.15%, respectively. The standardized mortality and standardized incidence of CRC in China had reached and gradually exceeded the global level since 2010. From 1990 to 2019, the overall standard incidence (AAPC=3.6%, P<0.05), standard mortality rate (AAPC=1.4%, P<0.05), and the standard DALY rate (AAPC=1.2%, P<0.05) of CRC in China showed an increasing trend. The incidence, mortality and DALY rates of males were higher than those of females, and gradually increased with age. Compared with 1990, the DALY, YLL, and YLD of CRC in 2019 increased by 134.3%, 127.69%, and 445.00%, and their corresponding standardized rates increased by 30.53%, 27.03%, and 187.29%, respectively, showing an overall upward trend.ConclusionsFrom 1990 to 2019, the standardized incidence rate and standardized mortality rate of colorectal cancer in China have had a continuously increasing trend, and males and the elderly are high-risk groups. To reduce the burden of colorectal cancer in China, effective measures should be taken for prevention and management.
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.
