ObjectiveBy comparing the epidemiological characteristics of the incidence and death of female breast cancer in China and the United States, the differences in prevention and screening strategies between China and the United States were analyzed to explore the prevention and control measures of female breast cancer in China. MethodsBased on the relevant data released by the Global Burden of Disease in 2020, the National Cancer Center of China, and the China Health Statistical Yearbook, the new cases and deaths of breast cancer in Chinese and American women in 2023 were estimated respectively, and the incidence, mortality and time trend of breast cancer in Chinese and American women were analyzed. ResultsIn China, 376 789 new cases of female breast cancer and 116 791 deaths were expected in 2023. In the United States, approximately 297 790 women were expected to be newly diagnosed with breast cancer in 2023, representing approximately 15.2% of new cancer cases. About 43 170 women died from breast cancer, accounting for about 7.1% of all cancer deaths. The incidence of breast cancer in women in the United States during the period 1975–2020 gradually increased and then stabilized; In contrast, the incidence of breast cancer among Chinese women increased year by year during the period 1990–2020. In recent years, the incidence and mortality rates of breast cancer in Chinese women had increased more than those in the United States, and there was a large difference between urban and rural areas in China. ConclusionsBoth China and the United States face a large burden of female breast cancer, and the characteristics of female breast cancer in China are similar to those in the United States. To reduce the burden of breast cancer in Chinese women, further efforts should be made in various aspects, such as strengthening breast cancer education, raising public health awareness, improving diet structure, cultivating healthy lifestyle, increasing screening efforts, and improving medical level.
ObjectiveTo explore the clinical application value of antithrombin Ⅲ (ATⅢ) in pulmonary thromboembolism (PTE).MethodsA retrospective study included 204 patients with confirmed PTE who were admitted to Fujian Provincial Hospital from May 2012 to June 2019. The clinical data of the study included basic conditions, morbilities, laboratory examinations and scoring system within 24 hours after admission. The relationship between ATⅢ and PTE in-hospital death was analyzed, and the value of ATⅢ to optimize risk stratification was explored.ResultsFor ATⅢ, the area under receiver operating characteristic curve (AUC) of predicting in-hospital mortality was 0.719, with a cut-off value of 77.7% (sensitivity 64.71%, specificity 80.21%). The patients were divided into ATⅢ≤77.7% group (n=48) and ATⅢ>77.7% group (n=156) according to the cut-off value, and significant statistically differences were found in chronic heart failure, white blood cells count, platelets count, alanine aminotransferase (ALT), albumin and troponin I (P<0.05). According to the in-hospital mortality, patients were divided into a death group (n=17) and a survival group (n=187), and the differences in count of white blood cells, ATⅢ, D-dimer, ALT, albumin, estimated glomerular filtration rate and APACHEⅡ were statistically significant. Logistic regression analysis revealed that ATⅢ≤77.7% and white blood cells count were independent risk factors for in-hospital death. The risk stratification and the risk stratification combined ATⅢ to predict in-hospital death were evaluated by receiver operating characteristic curve, and the AUC was 0.705 and 0.813, respectively (P<0.05). A new scoring model of risk stratification combined with ATⅢ was showed by nomogram.ConclusionsATⅢ≤77.7% is an independent risk factor for in-hospital death, and is beneficial to optimize risk stratification. The mechanism may be related to thrombosis, right ventricular dysfunction and inflammatory response.
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.
Objective To compare the early and late outcomes of different techniques of proximal root reconstruction during the repair of acute type A aortic dissection, including aortic valve (AV) resuspension, isolated supracoronary ascending aorta replacement, and aortic root replacement procedure (Bentall). Methods All patients who underwent acute Type A aortic dissection repair between January 2010 and December 2015 in Fuwai Hospital were retrospectively analyzed in our study. There were 673 patients with 512 males and 161 females at mean age of 48.80±11.22 years. There were 403 patients as an AV resuspension group (287 males and 116 females at average age of 50.61±9.95 years), 95 patients as an isolated supracoronary ascending aorta replacement group (76 males and 19 females at average of 49.83±12.21 years), and 175 patients as an AV resuspension group (149 males and 26 females at average of 44.07±11.99 years). The differences of preoperative aortic insufficiency, intraoperative variables and postoperative aortic insufficiency were compared in the three groups. Results Five hundred ninety-one patients (87.8%) had aortic valve commissure involved. The proportion of mild degree, moderate degree, and severe degree among the three groups were statistically significant (31.7%, 52.4%, 15.9%; 87.4%, 12.6%, 0.0%; 23.4%, 56.0%, 20.6%; P < 0.01). The diameter of aortic sinus in the three groups was 39.06±5.11 mm, 38.27±4.41 mm, 50.39±6.22 mm, respectively, with a statistical difference ( P< 0.01). The duration of surgery, cardiopulmonary bypass time, aorta cross-clamp time were also statistically significant (P < 0.01). The in-hospital mortality was 11.73% in the whole group. There was no difference among the three groups (12.2% vs. 13.7% vs. 9.7%, P=0.58). Five-year survival rate was similar (83.06% vs. 81.27% vs. 83.05%, P=0.85). The 5-year free from over moderate aortic insufficiency rate were 95.2%, 98.6% and 100% respectively, with no statistical difference (P=0.07). There was no re-do operation for aortic root diseases in the whole group. Conclusion According to aortic root processing strategy in our center, AV resuspension, isolated supracoronary ascending aorta replacement, and aortic root replacement can achieve satisfactory results. However, there is higher incidence of aortic insufficiency through AV resuspension. Further study is needed to evaluate its efficacy.
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.
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.
Avoidable mortality (AM) is an important indicator of health system performance. It is also an effective tool for evaluating the effectiveness of health measures and allocation of health resources. The concept development, analytical methods, and research contents of avoidable mortality are introduced in this study. This study investigated the applicability of avoidable mortality analysis in determining priority health-service intervention areas, determining priority health-service intervention populations and evaluating the quality of those services. This paper also discussed the significance and limitations of avoidable mortality analysis. The investigation provided references for further research and application of avoidable mortality analysis.
Objective Sedation and/or analgesia is often applied during noninvasive positive pressure ventilation (NIPPV) to make patients comfortable, and thus improve the synchronization between patients and ventilator. Nevertheless, the effect of sedation and/or analgesia on the clinical outcome of the patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) after extubation remains controversial. Methods A retrospective study was conducted on patients with AECOPD who received NIPPV after extubation in seven intensive care units in West China Hospital, Sichuan University between December 2013 and December 2017 . A logistic regression model was used to analyze the association between the use of sedation and/or analgesia and clinical outcomes including rate of NIPPV failure (defined as the need for reintubation and mechanical ventilation), hospital mortality, and length of intensive care unit stay after extubation. Results A total of 193 patients were included in the analysis, and 62 cases of these patients received sedation and/or analgesia during NIPPV. The usage of sedation and/or analgesia could result in failure of NIPPV (adjusted odd ratio [OR] 0.10, 95% confidence interval [CI] 0.02 - 0.52, P=0.006) and death (adjusted OR=0.13, 95%CI 0.04 - 0.42, P=0.001). Additionally, intensive care unit stay after extubation was longer in the patients who did not receive sedation and/or analgesia than those who did (11.02 d vs. 6.10 d, P< 0.01). Conclusion The usage of sedation and/or analgesia during NIPPV can decrease both the rate of NIPPV failure and hospital mortality in AECOPD patients after extubation.
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.
Objective To explore the risk factors of premature infants death. Methods The medical records of hospitalized premature infants admitted to West China Second University Hospital of Sichuan University between January 2015 and December 2022 were collected. Premature infants were divided into the death group and the non-death group (control group) based on discharge diagnosis of death. Parturient and premature infants related information were collected, and the disease classification and diagnosis of premature infants were analyzed. Results A total of 13 739 premature infants were included, with 53 deaths and a mortality rate of 3.85‰ (53/13 739). The ages of death were 1-49 days, and the median age of death was (9.68±9.35) days. According to the matching method, 212 premature infants were ultimately included. Among them, there were 53 premature infants in the death group and 159 premature infants in the control group. Compared with the control group, premature infants in the death group had lower gestational age, birth weight, lower 1-minute Apgar scores, lower 5-minute Apgar scores and shorter hospital stay (P<0.05), and received more delivery interventions (P<0.05). There was no statistically significant difference in other indicators between the two groups of premature infants (P>0.05). A total of 212 parturient were included. Among them, there were 53 parturients in the death group and 159 parturients in the control group. The use rate of prenatal corticosteroids in the control group was higher than that in the death group (55.35% vs. 54.72%). There was no statistically significant difference in other related factors between the two groups of parturient (P>0.05). The results of logistic regression analysis showed that longer hospital stay [odds ratio (OR)=0.891, 95% confidence interval (CI) (0.842, 0.943), P<0.001], prenatal use of corticosteroids [OR=0.255, 95%CI (0.104, 0.628), P=0.003] reduced the risk of premature infant death. However, tracheal intubation [OR=10.738, 95%CI (2.893, 39.833), P<0.001] increased the risk of premature infant death. Conclusions Clinicians should pay attention to prenatal examination of newborns and pay attention to evaluation of newborn status. Obstetricians and neonatologists should make joint plans for women with high risk factors for preterm delivery. During the hospitalization, after the diagnosis is clear, standardized treatment should be carried out in strict accordance with the guidelines for systemic diseases and expert consensus.
