Objective To analyze the results of intra-aortic balloon pump (IABP) support in patients receiving coronary artery bypass graft (CABG) and the risk factors of postoperative death. Methods The clinical data of 334 patients undergoing CABG procedure and receiving IABP support in Fuwai Hospital from January 1999 to April 2012 were retrospectively analyzed. According to the IABP insertion timing, the patients were divided into three groups: pre-, intra- and postoperative IABP groups. There were 45 males and 11 females aged 60.5±10.7 years in the preoperative IABP group, 84 males and 23 females aged 61.1±8.4 years in the intraoperative IABP group and 119 males and 52 females aged 61.4±8.5 years in the postoperative IABP group.Outcomes of the three groups were compared, including mortality, major complications, ICU stay, hospital stay and total costs. Multivariable logistic regression analysis was used to predict independent risk factors for postoperative in-hospital death. Results The total in-hospital mortality was 16.8% (56/334). Mortality was significantly different among the pre-, intra- and postoperative IABP groups (3.6% vs.23.4%vs. 17.0%, P=0.006). There was no significant difference in complications among the three groups (P=0.960). Multivariable logistic regression analysis indicated that independent risk factors for postoperative mortality included old age (OR=1.05, P=0.040), female (OR=3.34, P<0.001) and increasing left ventricular end-diastolic diameter (LVEDD,OR=1.06, P=0.040). Preoperative IABP support was protective factor (OR=0.10, P=0.050). Conclusion The results of IABP support in CABG patients are satisfactory, and patients with preoperative IABP have a lower mortality. Risk factors for postoperative death include old age, female and increasing LVEDD. Preoperative IABP support is a protective factor.
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.
ObjectiveTo investigate the effect of polymyxin B hemoperfusion on the prognosis of patients with sepsis and septic shock by meta-analysis.MethodsSupplemented by manual search and document traceability, the US National Library of Medicine Pubmed, the Dutch Medical Abstracts Embase database, and the Cochrane clinical trial database were searched. Randomized controlled trials (RCTs) were collected from January 1998 to October 2018 for the treatment of sepsis and septic shock with polymyxin B hemoperfusion, only limited to English publications. The collected RCTs were evaluated and the prognosis of patients with sepsis and septic shock was analyzed by the Cochrane Collaboration.ResultsFinally six RCTs were included, and a total of 926 patients were analyzed, with 471 patients in the polymyxin B hemoperfusion group and 455 patients in the control group. The mortality rate was 36.3% (171/471) in the polymyxin B hemoperfusion group and 39.1% (178/455) in the control group. Hemoperfusion with polymyxin B could not reduce the patient mortality (RR=0.80, 95% CI 0.56 to 1.15, P=0.233). A subgroup analysis was taken on the patients with moderate to severe septic shock. Four RCTs were included in total and 418 patients were analyzed, with 207 patients in the polymyxin B hemoperfusion group and 211 in the control group. The mortality rate was 38.65% (80/207) in the polymyxin B hemoperfusion group and 50.71% (107/211) in the control group were. The hemoperfusion of polymyxin B could significantly reduce the mortality of patients with moderate to severe septic shock (RR=0.70, 95% CI 0.52 to 0.96, P=0.025).ConclusionsOlymyxin B hemoperfusion can not improve the prognosis of patients with sepsis and septic shock. However, compared with conventional treatment, polymyxin B hemoperfusion can improve the 28-day mortality rate of patients of severe septic shock. Due to the limit number of randomized controlled trials, more high-quality trials are needed to a further confirmation.
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.
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 investigate risk factors of in-hospital death of patient after heart valve replacement (HVR) in Xinjiang. MethodsWe retrospectively analyzed clinical data of 214 patients undergoing HVR in the First Teaching Hospital of Xinjiang Medical university from January 2011 to Month 2014. There were 96 male and 118 female patients with their age of 49.91±13.27 years. According to their postoperative prognosis, all the patients were divided into a death group (21 patients) and a survival group (193 patients). Risk factors of perioperative death were analyzed. ResultsIn-hospital mortality was 9.81% (21/214). There was statistical difference in preoperative prothrombin time (PT), incidences of left ventricular ejection fraction (LVEF)≤50%, NYHA classⅣ, pulmonary arterial pressure (PAP) > 60 mm Hg, cardiopulmonary bypass time≥2 hours, concomitant coronary artery disease and renal failure between the 2 groups (P < 0.05). Logistic regression analysis showed that shortened preoperative PT, PAP > 60 mm Hg, NYHA classⅣand LVEF≤50% were independently risk factors of in-hospital death after HVR (P < 0.05). ConclusionsIndependent risk factors of in-hospital death of patients after HVR in Xinjiang include shortened preoperative PT, PAP > 60 mm Hg, NYHA classⅣand LVEF≤50%. Heightened caution is needed for patients with above risk factors to receive HVR after correction of those risk factors.
Objective To systematically review the epidemic trend and disease burden of ischemic stroke in the Chinese population and to provide references for formulating reasonable prevention and treatment measures and allocating health resources. Methods Based on Global Burden of Disease (GBD) data, we analyzed the morbidity, mortality, disability-adjusted life year (DALY) and normalized rates for ischemic stroke in China from 1990 to 2019 and evaluated the changes in the disease burden by sex and age group. Meanwhile, joinpoint regression model was constructed to analyze the time trend change in each stage during the study period. Results Compared with 1990, the incidence, mortality and DALY rate of ischemic stroke in China increased by 171.68%, 125.60% and 98.60% in 2019, among which the incidence, mortality and DALY rate of males increased by 184.29%, 148.96% and 115.16%, respectively; the morbidity, mortality and DALY rates of females increased by 160.9%, 101.32% and 81.44%, respectively. The age-standardized incidence increased by 34.70%, while the age-standardized mortality and age-standardized DALY rate decreased by 3.33% and 4.02%, respectively; the age-standardized incidence, mortality and DALY rates of males increased by 39.52%, 8.03% and 3.68%, respectively; the age-standardized incidence rate of females increased by 31.40%, while the age-standardized mortality rate and age-standardized DALY rate decreased by 14.02% and 11.53%, respectively. In 2019, both the mortality rate and DALY rate due to ischemic stroke increased with age, and the highest rate was found in the population over 85 years old. Males over 60 years old were significantly than females. In the 55-84 age group, the incidence of ischemic stroke in females was higher than that in males, while in the 85 and above age group, the incidence of ischemic stroke in females was lower than that in males. The AAPC of age-standardized incidence, age-standardized mortality, and age-standardized DALY rates due to ischemic stroke from 1990 to 2019 were 1.06% (95%CI 1.00% to 1.11%), 0.01% (95%CI ?0.45% to 0.48%) and ?0.16% (95%CI ?0.53% to 0.22%), respectively. All indicators of the AAPC for males were higher than those for females. ConclusionThe curvent age-standardized mortality and DALY rate of ischemic stroke in China have decreased slightly compared with 1990. The crude mortality, morbidity and disease burden have significantly increased. All indicators of the AAPC for males were higher than those for females. To reduce the epidemic trend and disease burden of ischemic stroke, reasonable prevention and treatment measures and rational allocation of health resources should be made according to sex and age.
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.
Objective To investigate the differences in postoperative mortality and identify potential influential factors in patients with a systemic left ventricle (SLV) versus a systemic right ventricle (SRV) following total cavopulmonary connection (TCPC). MethodsWe retrospectively collected data from functional single ventricle patients who underwent TCPC at the Department of Cardiac Surgery, Guangdong Provincial People’s Hospital, between October 2004 and July 2021. The cohort was categorized based on ventricular morphology into two groups: a SLV group and a SRV group. All procedures were performed via a median sternotomy under cardiopulmonary bypass. ResultsA total of 195 patients were included, comprising 108 patients in the SLV group (69 males, 39 females) and 87 in the SRV group (61 males, 26 females). The median age at surgery was 5.7 (IQR, 4.0-11.2) years, and the median body mass index (BMI) was 15.1 (IQR, 13.5-16.2) kg/m2 for the SLV group. For the SRV group, the median age was 5.7 (IQR, 4.1-8.9) years, and the median BMI was 14.7 (IQR, 13.6-15.9) kg/m2. The proportion of patients with situs inversus, heterotaxy syndrome, and moderate or greater atrioventricular valve regurgitation was significantly higher in the SRV group. Patients in the SRV group had a higher rate of fenestration and experienced longer aortic cross-clamp, cardiopulmonary bypass, and operative times, as well as prolonged postoperative hospital stays and chest tube durations. However, there were no statistical differences in early or late mortality between the two groups (P>0.05). Multivariate analysis identified pulmonary vascular resistance, postoperative aspartate aminotransferase, and postoperative creatinine as independent risk factors for mortality, while postoperative percutaneous oxygen saturation and hemoglobin levels were identified as protective factors. Conclusion The post-TCPC survival rate in patients with a SRV is non-inferior to that in patients with a SLV. However, the overall long-term mortality for both groups remains high, warranting close monitoring of the long-term survival outcomes in this patient population.
