ObjectiveTo investigate the associations of preoperative red cell distribution width (RDW) with mortality and morbidity in patients underwent liver transplantation. MethodsThis investigation was a retrospective study, the patients underwent liver transplantation met the inclusion criteria from June 2017 to May 2020 in the West China Hospital of Sichuan University were enrolled. The patients were divided into RDW≤14.5% group and RDW>14.5% group according to the normal RDW critical value (14.5%). The propensity score matching (PSM) was used to adjust the baseline characteristics. The primary outcome was 1-year mortality. The secondary outcomes included 1-year survival, 30-day mortality, incidence of early allograft dysfunction, acute kidney injury, renal replacement therapy, and pulmonary complications, as well as ICU stay and postoperative hospital stay. ResultsA total of 303 patients who met the analysis conditions were included. After PSM, 57 patients in each group were matched. There were no significant differences between the two groups in the baseline data such as the gender, age, body mass index (BMI), initial diagnosis, MELD score, Child-Pugh grade of the recipients, and the gender, age, and BMI of the donors (P>0.05). The 1-year [22.8% (13/57) versus 5.3% (3/57), χ2=7.27, P=0.007] and 30-day [15.8% (9/57) versus 3.5% (2/57), χ2=4.93, P=0.026] mortality of the patients with RDW >14.5% were higher than that of the patients with RDW ≤14.5% . The Kaplan-Meier survival curve showed that the 1-year survival of the patients with RDW ≤14.5% after liver transplantation was better than that of the patients with RDW >14.5% [hazard ratio=4.75, 95%CI (1.78, 12.67), P=0.007], but there were no significant differences between the two groups in the incidence of early graft dysfunction, acute renal injury, renal replacement therapy, and pulmonary complications, as well as postoperative hospital stay and ICU stay (P>0.05). ConclusionPreliminary results of this study indicate that preoperative RDW of patients underwent allogeneic liver transplantation is associated with1-year mortality, 30-day mortality, and 1-year survival.
ObjectiveTo systematically review the prevalence of elder abuse in China.MethodsPubMed, EMbase, Web of Science, CNKI, VIP and WanFang Data databases were electronically searched to collect cross-sectional studies on the prevalence of elder abuse in China from inception to June 2019. Two reviewers independently screened literature, extracted data and assessed risk bias of included studies; then, meta-analysis was performed by R 3.5.1 software.ResultsA total of 11 cross-sectional studies involving 23 020 subjects were included. The results of meta-analysis showed that the prevalence of abuse among the elderly in China was 20.29% (95%CI 12.9% to 28.9%). The highest prevalence of elder abuse subtype was psychological abuse with 15.06% (95%CI 10.2% to 20.6%). The prevalence rates were 20.1% in male and 23.64% in female. The prevalence rates in individuals aged between 60 to 70, 70 to 80 and above 80 were 19.76%, 22.24% and 29.19%, respectively. Illiterates and non-illiterates were 29.39% and 22.52% respectively. Normal marital status was 28.24%, and abnormal status was 31.38%. The elderly living alone was the highest (50.67%), compared with family residents (39.42%) and elderly living in pension institutions (29.94%). The elderly without chronic diseases (16.05%) was lower than elderly with chronic diseases (25.49%), and elderly having normal capability of daily living (26.89%) was lower than elderly having reduced capability of daily living (48.78%). Urban residents were 18.46%, while rural residents were 19.69%.ConclusionsThere is a high incidence of elder abuse in China, and it tends to increase with the increase of age. There are certain differences in the prevalence of elder maltreatment among different genders, ages, educational levels, marital status, living forms and spaces, and health conditions. Due to limited quality and quantity of the included studies, more high quality studies are required to verify the above conclusion.
ObjectiveTo investigate the incidence of perioperative anemia and the influencing factors of preoperative anemia in patients with colorectal cancer.MethodsThe clinicopathological data of 1 250 patients with colorectal cancer who underwent surgery in our hospital from January 1, 2019 to December 31, 2019 were analyzed retrospectively. According to the preoperative hemoglobin level, patients were divided into anemia group and non-anemia group. Univariate analysis and multivariate logistic regression analysis were used to explore the influencing factors of preoperative anemia in patients with colorectal cancer, and the effects of preoperative anemia on intraoperative blood transfusion, postoperative complications, and postoperative hospital stay were analyzed.ResultsThe incidence of preoperative anemia in patients with colorectal cancer was 40.6% (508/1 250), and the incidence of preoperative anemia in patients with right colon cancer, left colon cancer, and rectal cancer was 66.0% (192/291), 41.1% (139/338), and 28.5% (177/621), respectively. The incidence of postoperative anemia in patients with colorectal cancer was 69.4% (867/1 250), and the incidence of postoperative anemia in patients with right colon cancer, left colon cancer, and rectal cancer was 81.8% (238/291), 68.9% (233/338), and 63.8% (396/621), respectively. Multivariate logistic regression analysis showed that age >60 years old, nutritional risk screening 2002 ≥3, right colon cancer, T3–4 stage, and M1 stage were risk factors for preoperative anemia in patients with colorectal cancer (P<0.05). The rate of intraoperative blood transfusion and the incidence of postoperative complications in the preoperative anemia group of patients with colorectal cancer were higher than those in the non-anemia group (P<0.05). The postoperative hospital stay in the preoperative anemia group of patients with colon cancer was longer than that in the non-anemia group (P<0.05).ConclusionsThe incidence of perioperative anemia in patients with colorectal cancer is high. Advanced age, high nutritional risk, right colon cancer, T3–4 stage, and distant metastasis were the risk factors of preoperative anemia in patients with colorectal cancer. Preoperative anemia can increase the demand for intraoperative blood transfusion and the incidence of postoperative complications in patients with colorectal cancer, and prolong postoperative hospital stay of colon cancer patients.
Objectives To systematically review the efficacy of conservative treatment and open reduction with internal fixation for multiple rib fractures. Methods We searched WanFang Data, CNKI, VIP, PubMed, EMbase, The Cochrane Library and Web of Science from inception to December 2017 to collect studies on conservative treatment and open reduction with internal fixation for multiple rib fractures. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. RevMan 5.3 software was used for meta-analysis. Results A total of 16 studies were included, involving 1 374 patients, 723 patients in the surgical group and 651 patients in the conservative group. The meta-analysis showed that the length of stay in the ICU (MD=–3.41, 95%CI –4.92 to –2.43, P<0.000 01), total length of stay (MD=–7.60, 95 %CI–10.67 to–4.53,P<0.000 01), incidence of pulmonary arylene (RR=0.40, 95%CI 0.29 to 0.54,P<0.000 01), incidence of lung infections (RR=0.43, 95%CI 0.30 to 0.61,P<0.000 01), and incidence of chest wall malformation (RR=0.05, 95%CI 0.03 to 0.11,P<0. 0.000 01) in the surgical group were superior to the conservative group. Conclusions Compared with conservative treatment, open reduction with internal fixation can significantly improve the recovery time of patients with multiple rib fractures, reduce hospitalization time, the incidence of perioperative complications, and significantly enhance the prognosis of patients, which is more conducive to the rehabilitation of patients.
Objective To investigate the suicide related factors of the teenagers after trauma and further discuss the prevalence and related factors of suicide idea plan and behavior. Methods Using the general information questionnaire and the Youth Risk Behavior Survey (YRBS) to investigate the primary and secondary students in the nine worst-hit areas in Wenchuan earthquake of 2008, with cluster random sampling and the class as a sampling unit, to extract random 110 primary and middle schools and gather their general information, disaster-related cases and scores of suicide in YRBS. According to the different types of data, we used descriptive statistics,t test,Chi square test and Logistic regression analysis and respectively use single factor analysis and multivariate logistic regression analysis for suicide idea, plan and behavior. Results A total of 7 833 questionnaires were sent out and a total of 7 521 questionnaires were collected and the recovery rate was 96. 02%. Among them, there were 6 875 valid questionnaires (91.41%) and 636 invalid questionnaires. According to the investigation, the prevalence of the primary and secondary students which had seriously considered suicide was 6. 90%, which had a plan to commit suicide was 4.00% and which tried to take over the action of suicide was 2.70%. With general information for the independent variable, logistic regression analysis showed that whether there had seriously considered suicide as the dependent variable: age (OR=1.178, 95%CI 1.098 to 1.178) and changed in family structure after the earthquake (OR=1.360, 95%CI 1.360 to 1.085) were risk factors for post disaster the teenagers with suicide idea; whether there had been plan to commit suicide as the dependent variable: age (OR=1.099, 95%CI 1.050 to 1.150), the history of being buried in ruin (OR=2.155, 95%CI to 1.104 to 4.205) and changed in family structure after the earthquake (OR=1.495, 95%CI 1.128 to 1.981) were risk factors for post disaster the teenagers with suicide plan; whether took over the action of suicide as the dependent variable: male (OR=1.513, 95%CI 1.122 to 2.039) and changed in family structure after the earthquake (OR=1.555, 95%CI 1.112 to 2.175) were risk factors for post disaster the teenagers with suicide behavior. Conclusion Age and changed in family structure after the earthquake were the risk factors for suicide idea and age was positively correlated with suicidal idea. Age, had the history of being buried in ruin and changed in family structure after the earthquake were the risk factors for suicide plan and age was positively associated with suicide plan. Male and changed in family structure after the earthquake were the risk factors for suicide behavior. Among them, changed in family structure after the earthquake was the common risk factor. So there should be targeted psychological assessment and psychological rehabilitation intervention to avoid the risk of suicide among the teenagers after the disaster.
ObjectiveTo comprehensively evaluate the incidence of venous thromboembolism (VTE) after colorectal surgery.MethodsWe searched PubMed/Medline, Web of science, and Embase databases by computer, collected studies by using the combination of corresponding English keywords. Then, we screened literatures according to inclusion and exclusion criteria, and evaluated the quality of literatures by using Downs and Black tools. Finally, we used Stata 15.1 and R Project 3.4.1 for meta-analysis.ResultsA total of 15 studies (n=721 730) were included in the meta-analysis. The combined incidence of VTE after colorectal surgery was 2.26% [95% CI was (1.93%, 2.61%), P<0.000 1], and the incidence of VTE after adjusting for publication bias was 1.82% [95% CI was (1.53%, 2.13%), P<0.000 1]. Meta regression analysis revealed that patients’ age (P<0.000 1), smoking (P=0.000 4), open surgery (P=0.020 0), preoperative albumin level (P=0.023 6), and malignant tumor (P=0.036 4) were correlated with the incidence of VTE after colorectal surgery, which may be potential factors for heterogeneity.ConclusionsThe incidence of VTE after colorectal surgery is not insignificant. It is necessary for clinicians to be vigilant about the occurrence of VTE after colorectal surgery and provide appropriate preventive interventions in combination with patients’ own risk factors, disease-related factors, and surgical factors.
Objective To study the incidence and etiological distribution of lower respiratory tract infection (LRTI) after airway metal stent implantation in patients with malignant central airway obstruction (MCAO). Methods The clinical data of 149 patients with MCAO who underwent airway metal stent implantation in Department of Pulmonary and Critical Care Medicine of Hunan Provincial People's Hospital from April 2014 to April 2021 were selected for a retrospective study. The incidence of LRTI after treatment was counted. According to whether LRTI occurred after operation, they were divided into infected group and uninfected group. The clinical data of the two groups were compared and the influencing factors of LRTI were analyzed. Sputum samples and/or bronchoalveolar lavage fluid samples from patients infected with LRTI were collected for pathogen detection and drug susceptibility test, and the distribution and drug resistance of main pathogens were analyzed. Results A total of 149 patients who met the criteria were included in this study and the incidence of LRTI was 21.48%. People in the infected group was older than that in the uninfected one, and the proportion of people with a history of smoking, chemoradiotherapy, covered metal stents, and stent-related granulation tissue proliferation was higher, and the proportion of people with postoperative standardized aerosol inhalation was lower (P<0.05). Age, smoking history, chemoradiotherapy, covered metal stents, stent-related granulation tissue hyperplasia and postoperative standardized aerosol inhalation were all influencing factors of LRTI in these patients (P<0.05). A total of 38 pathogens were detected in 32 patients with LRTI. Gram negative bacteria, gram positive bacteria and fungi accounted for 68.42% (26/38), 21.05% (8/38) and 10.53% (4/38) respectively. Pseudomonas aeruginosa, the main Gram-negative bacteria, had no resistance to tobramycin, gentamicin and amikacin, but had high resistance to compound sulfamethoxazole, tigecycline and ampicillin; Klebsiella pneumoniae had low resistance to tobramycin, amikacin and tigecycline, and high resistance to cefotaxime, ciprofloxacin and cefepime; the main Gram-positive Staphylococcus aureus had no drug resistance to vancomycin, linezolid, compound sulfamethoxazole and quinuptin/dafuptin, but had high drug resistance to tetracycline, penicillin G, levofloxacin, oxacillin and ciprofloxacin; the main fungi Candida albicans showed no resistance to fluconazole, itraconazole, voriconazole, 5-fluorocytosine and amphotericin B. These results of pathogenic detection and drug susceptibility test contributed to the improvement of the rational application rate of antibiotics. Conclusions LRTI occurs in about a quarter of patients with MCAO after airway metal stent implantation. The pathogens are mainly Pseudomonas aeruginosa and Staphylococcus aureus. Antimicrobial treatment should be based on the results of etiological detection and drug susceptibility test.
