Objective To evaluate the risk factors for postoperative in-hospital mortality in elderly patients receiving cardiac valvular surgery, and develop a new prediction models using the least absolute shrinkage and selection operator (LASSO)-logistic regression. Methods The patients≥65 years who underwent cardiac valvular surgery from 2016 to 2018 were collected from the Chinese Cardiac Surgery Registry (CCSR). The patients who received the surgery from January 2016 to June 2018 were allocated to a training set, and the patients who received the surgery from July to December 2018 were allocated to a testing set. The risk factors for postoperative mortality were analyzed and a LASSO-logistic regression prediction model was developed and compared with the EuroSCOREⅡ. Results A total of 7 163 patients were collected in this study, including 3 939 males and 3 224 females, with a mean age of 69.8±4.5 years. There were 5 774 patients in the training set and 1389 patients in the testing set. Overall, the in-hospital mortality was 4.0% (290/7163). The final LASSO-logistic regression model included 7 risk factors: age, preoperative left ventricular ejection fraction, combined coronary artery bypass grafting, creatinine clearance rate, cardiopulmonary bypass time, New York Heart Association cardiac classification. LASSO-logistic regression had a satisfying discrimination and calibration in both training [area under the curve (AUC)=0.785, 0.627] and testing cohorts (AUC=0.739, 0.642), which was superior to EuroSCOREⅡ. Conclusion The mortality rate for elderly patients undergoing cardiac valvular surgery is relatively high. LASSO-logistic regression model can predict the risk of in-hospital mortality in elderly patients receiving cardiac valvular surgery.
Objective To investigate the application of delayed sternal closure (DSC) following arterial switch operation for neonates with transposition of great arteries (D-TGA). Methods We retrospectively analyzed clinical data of 172 neonates underwent arterial switch operation with transposition of great arteries (D-TGA) between June 1st 2009 and December 31st 2015. These neonates were divided into 2 groups including a DSC group (118 patients with 99 males and 19 females) and a non-DSC group (54 patients with 47 males and 7 females). The outcome of the two groups were compared. Results Preoperative mechanical ventilation(P<0.001), emergency surgery (P=0.023) and extracorporeal circulation time (P<0.001) were the risk factors for delayed sternal closure. The incidence of complications of median sternotomy incision in the DSC group was not higher than that in the non-DSC group. The mortality rate in the DSC group was markedly higher than that in the non-DSC group (P<0.001). However, DSC was not a risk factor for the death of the neonates. Conclusion Delayed sternal closure does not increase the incidence of complications of the median sternotomy incision, nor is it a risk factor for the death of the neonates. Reasonable application of delayed sternal closure is helpful for early postoperative recovery of the neonates.
Blood pressure variability (BPV) is a novel predictor related to blood pressure level, and a large number of studies based on the hypertension cohort have shown that BPV is an independent predictor of target organ damages and cardiovascular adverse outcomes. Due to the significant hemodynamic changes, BPV in patients with chronic kidney disease (CKD) and hemodialysis is higher than the simple hypertension cohort, suggesting that BPV may be of great significance to patients with chronic kidney disease and hemodialysis. In recent years, studies based on CKD and hemodialysis cohort have published in succession whose results revealed that BPV of this cohort is of great prognostic significance for predicting target organ damages and cardiovascular disease risks. This article aims to provide an overview on these research, so as to survey and predict the clinical significance of BPV in CKD and hemodialytic patients.
Objective To investigate the correlation between monocyte-lymphocyte ratio (MLR) and intensive care unit (ICU) results in ICU hospitalized patients. Methods Clinical data were extracted from Medical Information Mart for Intensive Care Ⅲ database, which contained health data of more than 50000 patients. The main result was 30-day mortality, and the secondary result was 90-day mortality. The Cox proportional hazards model was used to reveal the association between MLR and ICU results. Multivariable analyses were used to control for confounders. Results A total of 7295 ICU patients were included. For the 30-day mortality, the hazard ratio (HR) and 95% confidence interval (CI) of the second (0.23≤MLR<0.47) and the third (MLR≥0.47) groups were 1.28 (1.01, 1.61) and 2.70 (2.20, 3.31), respectively, compared to the first group (MLR<0.23). The HR and 95%CI of the third group were still significant after being adjusted by the two different models [2.26 (1.84, 2.77), adjusted by model 1; 2.05 (1.67, 2.52), adjusted by model 2]. A similar trend was observed in the 90-day mortality. Patients with a history of coronary and stroke of the third group had a significant higher 30-day mortality risk [HR and 95%CI were 3.28 (1.99, 5.40) and 3.20 (1.56, 6.56), respectively]. Conclusion MLR is a promising clinical biomarker, which has certain predictive value for the 30-day and 90-day mortality of patients in ICU.
ObjectiveTo identify the risk factors for hospital mortality in patients with acute myocardial infarction (AMI) after emergency coronary artery bypass grafting (CABG).MethodsWe retrospectively analyzed the clinical data of 145 AMI patients undergoing emergency CABG surgery in Qingdao Municipal Hospital from 2009 to 2019. There were 108 (74.5%) males and 37 (25.5%) females with a mean age of 67.7±11.5 years. According to whether there was in-hospital death after surgery, the patients were divided into a survival group (132 patients) and a death group (13 patients). Preoperative and operative data were analyzed by univariate analysis, followed by multivariate logistic regression analysis, to identify the risk factors for hospital mortality.ResultsOver all, 13 patients died in the hospital after operation, with a mortality rate of 9.0%. In univariate analysis, significant risk factors for hospital mortality were age≥70 years, recent myocardial infarction, left ventricular ejection fraction (LVEF)<30%, left main stenosis/dissection, operation time and simultaneous surgeries (P<0.05). Multivariate logistic regression analysis showed that LVEF<30% (OR=2.235, 95%CI 1.024-9.411, P=0.014), recent myocardial infarction (OR=4.027, 95%CI 1.934-14.268, P=0.032), operation time (OR=1.039, 95%CI 1.014-1.064, P=0.002) were independent risk factors for hospital mortality after emergency CABG.ConclusionEmergency CABG in patients with AMI has good benefits, but patients with LVEF<30% and recent myocardial infarction have high in-hospital mortality, so the operation time should be shortened as much as possible.
ObjectiveTo analyze the changing trend of cancer burden in China from 2005 to 2020, so as to provide reference for the formulation of cancer prevention and control strategies. MethodBased on the report “National and subnational trends in cancer burden in China, 2005–20”, the overall changes in cancer deaths in China by gender, age, urban and rural areas, and different regions of the country were analyzed. Results① Among the whole population, the number of cancer-related deaths and years of life lost (YLLs) in China increased by 21.6% and 5.0% respectively, and the top third leading cause of cancer-related deaths ranked by mortality rate were tracheal, bronchus, and lung cancer, liver cancer, and stomach cancer. ② In different gender groups, for the males, the top five leading cause of cancer-related deaths by mortality rate remained unchanged from 2005 to 2020, they were tracheal, bronchus, and lung cancer, liver cancer, stomach cancer, oesophageal cancer, and colon and rectum cancer. The average annual percent change (AAPC) of the age-standardized mortality rate (ASMR) increased in 4 of the leading 10 cancers, followed by prostate cancer (1.70 per 100 000), pancreatic cancer (0.95 per 100 000), lymphoma (0.33 per 100 000), and colon and rectum cancer (0.31 per 100 000). For the females, the tracheal, bronchus, and lung cancer remained the first leading cancer from 2005 to 2020, the second to the fifth leading cancers by mortality rate showed evident changes, with the liver cancer moving from the third to the second position, the stomach cancer moving from the second to the third position, the colon and rectum cancers moving from the fifth to the fourth position, and the breast cancer moving from the sixth to the fifth position, the pancreatic cancer moving from the ninth to the eighth position. Among the top 10 cancers, only the pancreatic cancer had an increase in AAPC of ASMR (0.67 per 100 000). ③ Among different age groups, the cancer-related mortality in young people (18–44 years old) and middle-aged people (45–59 years old) was much lower than that of the elderly (over 60 years old). ④ The mortality and YLL rates due to cancer in rural areas were higher than those in urban areas for both sexes. The cancer mortality rates of 11 provinces or regions such as Anhui were higher than those the national average value. The mortality, ASMR, YLL rates, and age-standardized YLL rates of all cancer types in Guangxi Zhuang Autonomous Region, Hebei, Xinjiang Uygur Autonomous Region, Henan, and Qinghai decreased in the males and which in Jiangsu, Henan, Guangxi Zhuang Autonomous Region, Xinjiang Uygur Autonomous Region, and Shanghai in the females also decreased. The ASMR of the colon and rectum cancer and pancreatic cancer increased significantly in some provinces or regions.ConclusionsFrom 2005 to 2020, there are rising trends in the number of cancer-related deaths and YLLs in China, and there are differences in the gender, age, urban and rural, and regional distribution of cancer burden. The prevention and control situation is grim, there is an urgent need for a comprehensive cancer prevention and control strategy to deal with the changing cancer burden in China.
Objective To systematically evaluate the correlation between serum 25-hydroxyvitamin D [25(OH)D] level and mortality risk in adult with sepsis. Methods We searched PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure, Wanfang, and Chongqing VIP databases for studies on the correlation between serum 25(OH)D and mortality risk in adults with sepsis. The search period was from the establishment of databases to December 2023. Meta-analysis was conducted using RevMan 5.4 software. Results A total of 9 studies were included, with a total of 2267 patients. The meta-analysis results showed that sepsis patients with low serum 25(OH)D levels (<30 ng/mL), insufficient levels (20-30 ng/mL), and deficient levels (<20 ng/mL) had a higher mortality risk compared to those with normal levels (relative risk=1.96, 1.62, 2.21, P<0.05). Subgroup analysis based on different sepsis diagnostic criteria, regions, and research types also showed that sepsis patients with lower serum 25(OH)D levels (<30 ng/mL) had a higher mortality risk compared to those with normal levels (P<0.05). Conclusions Adult sepsis patients with low serum 25(OH)D levels have a higher mortality risk than those with normal levels.
ObjectiveTo compare the mortality in lung cancer patients infected with coronavirus disease 2019 (COVID-19) versus other cancer patients infected with COVID-19. MethodsA computer search of PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang database, VIP database and CNKI database was conducted to compare the mortality of lung cancer and other cancers patients infected with COVID-19 from the inception to December 2021. Two thoracic surgeons independently screened the literature, extracted data, and then cross-checked the literature. After evaluating the quality of the included literature, a meta-analysis was performed on the literature using Review Manager 5.4 software. ResultsA total of 12 retrospective cohort studies were included, covering 3 065 patients infected with COVID-19, among whom 340 patients suffered from lung cancer and the remaining 2 725 patients suffered from other cancers. Meta-analysis results showed that the lung cancer patients infected with COVID-19 had a higher mortality (OR=1.58, 95%CI 1.24 to 2.02, P<0.001). Subgroup analysis results showed that the mortality of two groups of patients in our country was not statistically different (OR=0.90, 95%CI 0.49 to 1.65, P=0.72). Whereas, patients with lung cancer had a higher mortality than those with other cancers in other countries (Brazil, Spain, USA, France, Italy, UK, Netherlands) (OR=1.78, 95%CI 1.37 to 2.32, P<0.001). ConclusionThere is a negligible difference in mortality between lung cancer and other cancers patients who are infected with COVID-19 in our country; while a higher mortality rate is found in lung cancer patients in other countries. Consequently, appropriate and positive prevention methods should be taken to reduce the risk of infecting COVID-19 in cancer patients and to optimize the management of the infected population.
ObjectiveTo observe the clinical characteristics and survival rate of the patients with extraocular retinoblastoma (RB). MethodsThis is a retrospective case analysis. From November 2003 to May 2015, 38 eyes of 31 patients with RB in the extra-ocular stage from 213 RB patients were enrolled in this study. There were 18 males and 13 females. Bilateral lesions were observed in 7 patients and unilateral lesions were observed in 24 patients.19 patients were diagnosed at less than 2 years old, 10 patients at 2 to 5 years old, and 2 patients at age over 5 years old. First visit time was less than 1 month in 12 patients, from 1 to 3 months in 15 patients, over 3 months to 6 months in 4 patients. Medical history and family history were record at the first visit. All patients underwent orbital CT, MRI, double color Doppler imaging and wide angle digital retinal imaging system. CT and (or) MRI examination detected tumor extraocular invasion. Histopathological examination showed that there were tumor cells invasion of the scleral, optic nerve root and optic nerve. Chemotherapy was done after surgery. In the extra-ocular stage, 3 to 6 rounds of intensive chemotherapy combined with orbital radiotherapy were done. The average follow-up period was (25.5±4.5) months after treatment. The cumulative survival rate was observed after 6 months, 1 and 5 years after treatment, and the relationship between the initial age, time, sex, single eye, tumor and survival time of the patients was analyzed. ResultsThe extraocular RB accounted 14.55% of all RB patients in this study. There is no family history of RB, no special history. There were 15 patients with leukocoria and yellow-white reflection in the pupil; 5 patients with lacrimation, swelling, photophobia and exophthalmos; 11 patients with strabismus. The cumulative survival rate at 6 months, 1, 5 years after treatment was (78.0±9.0)%, (62.0±11.0)%, (57.0±11.0)% respectively. The average survival time was (53.9±7.8) months; the cumulative survival rate was (59.3±11.3)%. When the age of first visit was less than 1 month, 1-3 months, 3-6 months, the median survival time was 78, 15 and 18 months respectively, the cumulative survival rate was 100.0%, (40.0±21.9)% and (25.0±21.7)%, respectively. The survival time of the newly diagnosed patients at 1 month was more than at 1 to 6 months, and the difference was statistically significant (t=9.20, P < 0.05). Conclusions14.55% of all RB patients was extraocular RB in this study. One of the most common clinical manifestations is leukocoria at the first visit. The cumulative survival rate of extraocular RB is lower, while the survival rate of patients with the age of first visit time was less than 1 month is higher.
ObjectiveTo compare the efficacy of three surgical approaches, including percutaneous transluminal angioplasty (PTA), PTA+bare metal stent (BMS), and Rotarex+PTA+drug coated balloon (DCB), in treating femoropopliteal artery lesions in arteriosclerosis obliterans (ASO), and to explore the prognostic factors of femoropopliteal artery lesions in ASO. MethodsA retrospective analysis was conducted on 314 patients with femoropopliteal artery lesions in ASO who were treated in the Department of Vascular and Thyroid Surgery in the First Affiliated Hospital of Xinjiang Medical University from March 2018 to March 2024. inverse probability of treatment weighting was used to balance the baseline characteristics of the three groups. The clinical examination, imaging examination, and ankle-brachial index (ABI) results of the three groups at 3 months, 12 months, and 24 months after surgery were compared. Log-rank test was used to compare the incidence of all-cause mortality (ACM) and major adverse limb events (MALEs) among the three groups, and Cox proportional hazards regression model was used to analyze the prognostic factors of femoropopliteal artery lesions in ASO. ResultsA total of 314 patients with ASO femoropopliteal artery lesions were enrolled, comprising 153 cases in the PTA group, 89 cases in the PTA+BMS group, and 72 cases in the Rotarex+PTA+DCB group. After inverse probability of treatment weighting based on propensity scores, baseline characteristics were balanced across all groups (all P>0.05). Postoperative follow-up results demonstrated the following patency rates: at 3 months, 58.4% (87/149) for the PTA group, 79.5% (66/83) for the PTA+BMS group, and 87.5% (63/72) for the Rotarex+PTA+DCB group; at 12 months, 78.0% (60/79), 68.3% (43/63), and 80.0% (44/55), respectively; and at 24 months, 98.1% (52/53), 89.7% (35/39), and 100.0% (43/43), respectively. The Rotarex+PTA+DCB group exhibited significantly superior patency rates, claudication distances, ankle-brachial index (ABI), and Rutherford classification compared to both the PTA and PTA+BMS groups at 3 months (P<0.05). Furthermore, the Rotarex+PTA+DCB group showed lower incidence of ACM/MALEs compared to the other two groups (χ2=18.70, P<0.001). Survival analysis revealed that the Rotarex+PTA+DCB group had significantly better survival outcomes compared to the PTA+BMS group (χ2=14.27, P<0.001) and the PTA group (χ2=3.92, P=0.016). Cox proportional hazards regression analysis identified elevated red cell distribution width (RDW) as an independent risk factor for ACM/MALEs following endovascular therapy in ASO patients, with a relative risk of 1.006 [95%CI (1.002, 1.011), P=0.006]. ConclusionsThe Rotarex+PTA+DCB demonstrate superior outcomes compared to both the PTA and PTA+BMS in terms of patency rate, claudication distance, ABI, and Rutherford classification at 3 months postoperatively, along with the better survival. Furthermore, elevated RDW may serve as a prognostic factor for adverse outcomes in patients with ASO femoropopliteal artery lesions.
