Objective To analyze the incidence and mortality of asthma in China from 1990 to 2019, and to explore the influence of age, period and cohort on the incidence and mortality of asthma. Methods Using the Global Burden of Disease (GBD) 2019 database, the incidence and mortality of asthma in China from 1990 to 2019 were analyzed, and the time variation trend of age-standardized incidence and mortality was analyzed by using Joinpoint software, and the average annual variation percentage was calculated. The age-period-cohort model was constructed to analyze the influence of age, period and birth cohort on the incidence and mortality trend of asthma. Results In 2019, the incidence of asthma in China was 264.44/100 000, and the mortality rate was 1.74/100 000. The incidence rate of asthma in males (300.94/100 000) and mortality rate (1.99/100 000) were higher than those in females (226.51/100 000 and 1.49/100 000). From 1990 to 2019, the age-standardized incidence of asthma in China showed a downward trend, but the trend was not statistically significant (P>0. 05), and the age-standardized mortality showed a downward trend, with an average annual decrease of 4.90%, with a statistically significant trend (P<0.05). The results of age effect showed that the incidence of asthma in China showed a downward trend, and the death first showed a downward trend, and then increased in the age group of 55-59. The results of period effect show that the risk of asthma is decreasing, and then it is increasing from 2015 to 2019, and the risk of asthma mortality is decreasing. The results of cohort effect show that the later people are born, the lower the risk of asthma onset and death. The death of asthma is attributed to behavioral risk, high body mass index and tobacco, and the occupational risk tends to decrease. ConclusionsFrom 1990 to 2019, the incidence and mortality of asthma in China showed a decreasing trend, and the incidence and mortality of men were higher than that of women. The risk factors of behavioral risk, high body mass index and tobacco were still on the rise, so corresponding measures should be taken to carry out early screening, early detection, and early treatment for key populations.
ObjectivesTo systematically review the prognostic value of plasma soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) level in predicting 28-day mortality in sepsis.MethodsPubMed, The Cochrane Library, EMbase, Web of Science, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect studies about the prognostic value of plasma sTREM-1 in early 28-day mortality in sepsis from inception to April 16th, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 14.0 software.ResultsA total of 13 studies involving 1 115 patients were included. The results of meta-analysis showed that the sensitivity and specificity were 79% and 77%, respectively. The positive likelihood ratio and the negative likelihood ratio were 3.4 and 0.28, respectively. The diagnostic ratio was 12. The overall area under the summary receiver operator characteristic (SROC) curve was 0.80.ConclusionsCurrent evidence shows that plasma sTREM-1, as a single index, may play a prognostic role in the early 28-day mortality of sepsis in patients. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
Objective To verify the association between admission serum phosphate level and short-term (<30 days) mortality of severe pneumonia patients admitted to intensive care unit (ICU) / respiratory intensive care unit (RICU). Methods Severe pneumonia patients admitted to the ICU/RICU of Quanzhou First Hospital Affiliated to Fujian Medical University from November 2019 to September 2021 were included in the study. Serum phosphate was demonstrated as an independent risk factor for short-term mortality of severe pneumonia patients admitted to ICU/RICU by logical analysis and receiver operator characteristic (ROC) curve. The patients were further categorized by serum phosphate concentration to explore the relationship between serum phosphate level and short-term mortality. Results Comparison of baseline indicators at admission between the survival group (n=54) and the non survival group (n=46) revealed that there was significant difference in serum phosphate level [0.9 (0.8, 1.2) mmol/L vs. 1.2 (0.9, 1.5) mmol/L, P<0.05]. Logical analysis showed serum phosphate was an independent risk factor for short-term mortality. ROC curve showed that the prediction ability of serum phosphate was close to pneumonia severity index (PSI). After combining serum phosphate with PSI score, CURB65 score, and sequential organ failure score, the predictive ability of these scores for short-term mortality was improved. Compared with the normophosphatemia group, hyperphosphatemia was found be with significantly higher short-term mortality (85.7% vs. 47.3%, P<0.05), which is absent in hypophosphatemia (25.8%). Conclusions Serum phosphate at admission has a good predictive value on short-term mortality in severe pneumonia patients admitted to the ICU/RICU. Hyperphosphatemia at admission is associated with a higher risk of short-term death.
Objective To systematically review the influence of frailty on the prognosis of non-cardiovascular surgery heart failure (HF) patients and to provide references for its prevention and management. Methods CNKI, VIP, CBM, WanFang Data, PubMed, EMbase, Web of Science, and The Cochrane Library were searched to collect cohort studies on the prognosis of non-cardiovascular surgery HF patients with frailty from inception to November 1st, 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Then, meta-analysis was performed using RevMan 5.3 software and Stata 14.0 software. Results A total of 20 studies involving 11 127 patients were included. The results of meta-analysis showed that frailty increased the risk of all-cause mortality (HR=1.72, 95%CI 1.61 to 1.84, P<0.000 01), hospitalization (HR=2.06, 95%CI 1.26 to 3.37, P=0.004), and combined endpoint (HR=1.59, 95%CI 1.37 to 1.84, P<0.000 01) in non-cardiovascular surgery HF patients. Conclusion Current evidence shows that frailty can increase the risk of all-cause mortality, hospitalization, and combined endpoints in non-cardiovascular surgery HF patients. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective To investigate the 30-day mortality risk factors in elderly patients (≥70 years) with heart failure with reduced ejection fraction (HFrEF) after isolated coronary artery bypass grafting (CABG) and to construct a nomogram for predicting mortality risk. Methods A retrospective analysis of elderly HFrEF patients undergoing isolated CABG at Tianjin Chest Hospital from 2010 to 2024. Simple random sampling in R was used to divide the dataset into training and validation sets in a 7 : 3 ratio. The training set was further divided into survivors and non-survivors. Univariate logistic regression was performed to identify differences between groups, followed by multivariate logistic stepwise regression to select independent risk factors for death and to establish a death-risk nomogram, which underwent internal validation. The predictive value of the nomogram was assessed by plotting receiver operating characteristic (ROC) curves, calibration curves, and decision-curve analyses for both the training and validation sets. ResultsA total of 656 patients were included. The training set consisted of 458 patients (survivors 418, deaths 40); the validation set consisted of 198 patients (survivors 180, deaths 18). In the training cohort, univariate analysis showed significant differences between survivors and deaths for creatinine (Cr) level, brain natriuretic peptide (BNP), maximum Cr, intra-aortic balloon pump (IABP) use, assisted ventilation, reintubation, hyperlactatemia, low cardiac output syndrome, and renal failure (P<0.05). After multivariable logistic regression with stepwise selection, five independent risk factors were identified: IABP use (OR=3.391, 95%CI 1.065–11.044, P=0.038), reintubation (OR=15.991, 95%CI 4.269–67.394, P<0.001), hyperlactatemia (OR=8.171, 95%CI 2.057–46.089, P=0.007), Cr (OR=4.330, 95%CI 0.997–6.022, P=0.024), and BNP (OR=1.603, 95%CI 1.000–2.000, P=0.010). Accordingly, a nomogram predicting mortality risk was constructed. The ROC and calibration analyses indicated good predictive value: training set AUC was 0.898 (95%CI 0.831–0.966); validation set AUC 0.912 (95%CI 0.805–1.000). Calibration and decision-curve analyses showed good agreement and clinical utility. Conclusion The nomogram incorporating IABP use, reintubation, hyperlactatemia, creatinine, and BNP provides good predictive value for 30-day mortality after CABG in elderly patients with HFrEF and demonstrates potential clinical utility.
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 investigate the efficacy and safety of laparoscopic surgery for overweight/obese patients with acute perforated or gangrenous appendicitis. MethodsFrom January 2007 to December 2014, patients with acute perforated or gangrenous appendicitis underwent laparoscopic (152 cases) or open (60 cases) appendectomy were collected, who were retrospectively classified into overweight/obese group (BMI≥25 kg/m2, n=69) or normal weight group (BMI < 25 kg/m2, n=143). Conversion rate, operation time, hospital stay, readmission, reoperation, and postoperative complications such as incision infection, abdominal abscess, and lung infection were analyzed. Results①The rate of conversion to open surgery had no significant difference between the overweight/obese group and the normal weight group[4.2% (2/48) versus 6.7% (7/104), χ2=0.06, P > 0.05].②The operation time of laparoscopic surgery in the overweight/obese group was significantly shorter than that of the open surgery in the overweight/obese group[(41.6±11.7) min versus (63.1±23.3) min, P < 0.01], which had no significant difference between the laparoscopic surgery in the overweight/obese group and laparoscopic surgery in the normal weight group[(41.6±11.7) min versus (39.6±12.7) min, P > 0.05].③The total complications rate and incision infection rate of the laparoscopic surgery in the overweight/obese group were significantly lower than those of the open surgery in the overweight/obese group[total complications rate:16.7% (8/48) versus 52.4% (11/21), χ2=9.34, P < 0.01; incision infection rate:4.2% (2/48) versus 33.3% (7/21), χ2=8.54, P < 0.01]. Although the total complications rate of all the patients in the overweight/obese group was increased as compared with all the patients in the normal weight group[27.5% (19/69) versus 14.7% (21/143), χ2=5.02, P < 0.01], but which had no significant difference between the laparoscopic surgery in the overweight/obese group and laparoscopic surgery in the normal weight group[16.7% (8/48) versus 12.5% (13/104), χ2=0.45, P > 0.05].④The reoperation rate of all the patients performed laparoscopic surgery was significantly lower than that of all the patients performed open operation[1.3% (2/152) versus 10.0% (6/60), χ2=6.7, P < 0.01].⑤The abdominal abscess rate, lung infection rate, and hospital stay after discharge had no significant differences among all the patients (P > 0.05). ConclusionLaparoscopic appendectomy could be considered a safe technique for overweight/obese patients with acute perforated or gangrenous appendicitis, which could not increase the difficulty of laparoscopic surgery and the perioperative risk.
Recently, World Health Organization/International Agency for Research on Cancer (WHO/IARC) published the World Cancer Report 2020.

Based on current status of China’s cancer burden and prevention strategies, this paper briefly interpreted the key points of cancer prevention and control in the report.
Objective To systematically evaluate the effect of vitamin C supplementation on the mortality of patients with sepsis and septic shock. Methods The Cochrane Library, PubMed, EMbase, Wanfang Data Knowledge Service Platform, China National Knowledge Infrastructure Database and Chinese Science and Technology Periodical Database were searched by computer for randomized controlled trials (RCTs) on the effect of vitamin C on the mortality of patients with sepsis. The retrieval time of each database was from the establishment of the database to January 20, 2022. Two researchers independently screened the literature, extracted data, and evaluated the quality, and then used STATA 16.0 software for meta-analysis. Results A total of 15 RCTs were included, with a total of 2077 patients, including 1041 in the experimental group and 1036 in the control group. The results of literature quality showed that 7 studieswere grade A and 8 studies were grade B, indicating that the overall quality of the included literature was good. The results of meta-analysis showed that compared with the control group, the mortality of patients with sepsis and septic shock in the experimental group were effectively reduced [odds ratio (OR)=0.81, 95% confidential interval (CI) 0.67 - 0.98, P=0.027]. The results of subgroup analysis showed that vitamin C supplementation therapy for more than 4 days could significantly reduce the mortality of the patients with sepsis (OR=0.67, 95%CI 0.49 - 0.90, P=0.008); single treatment could significantly reduce the mortality rate of patients with sepsis (OR=0.50, 95%CI 0.34 - 0.74, P=0.001); vitamin C supplementation can effectively reduce the short-term (≤30 days) mortality of patients with sepsis (OR=0.77, 95%CI 0.63 - 0.96, P=0.017). The funnel plot showed that the included literature was basically symmetrical, and publication bias could not be considered. Conclusions Vitamin C supplementation can effectively reduce the mortality rate of patients with sepsis and septic shock. Vitamin C supplementation treatment course of 4 days or less and single treatment can reduce the mortality rate of patients with sepsis and septic shock, but cannot reduce the long-term (90 days) mortality rate of patients.
Objective To explore relationship between body mass index and all-cause mortality or cancer-specific mortality of colorectal cancer. Methods The published articles relevant body mass index and colorectal cancer mortality were retrieved according to the inclusion and exclusion criteria from PubMed, Elsevier-Science Direct, and Web of Science databases. The meta-analysis was performed with RevMan 5.3 software. Results A total of 14 articles were eligible for the meta-analysis, involved 53 804 patients (colorectal cancer patients with underweight 1 853 cases, colorectal cancer patients with overweight 9 088 cases, colorectal cancer patients with obesity 4 463 cases). The results of meta-analysis showed that the colorectal cancer patients with obesity and underweight had the higher all-cause mortalities 〔RR=1.11, 95% CI (1.06, 1.16), P<0.000 01; RR=1.34, 95% CI (1.11, 1.61), P=0.002〕 and colorectal cancer-specific mortalities 〔RR=1.15, 95% CI (1.05, 1.24), P=0.001; RR=1.33, 95% CI (1.09, 1.62), P=0.005〕 as compared with the colorectal cancer patients with normal weight. The all-cause mortality and colorectal cancer-specific mortality had no significant differences between the colorectal cancer patients with overweight and the colorectal cancer patients with normal weight 〔RR=0.96, 95% CI (0.89, 1.04), P=0.31; RR=1.00, 95% CI (0.90, 1.12), P=0.98〕 . Conclusion Colorectal cancer patients with obesity and underweight might have a higher mortality rate.
