Abstract Background Endometrial hyperplasia (EH) is commonly-seen in the patients with endometrial cancer (EC), we aimed to evaluated the risk factors of EC in patients with EH, to provide evidence to the clinical prevention and treatment of EC. Methods This study was a retrospective study design. EH patients confirmed by pathological examinations and treated with hysterectomy in our hospital from June 1, 2018 to February 28, 2021 were included. The clinical characteristics of EC and no-EC patients were compared and analyzed. Logistics regression analyses were conducted to evaluate the risk factors of EC in patients with EH. Results A total of 228 EH patients were included, the incidence of EC in the EH patients was 31.58%. There were significant differences in the age, BMI, diabetes, hypertension and pathology of EH between EC and no EC groups (all P < 0.05), no significant differences in the hyperlipidemia, preoperative CA125, number of deliveries, menopause and endometrial thickness between EC and no EC groups were found (all P > 0.05). Logistic regression analyses indicated that age > 50 y (OR 3.064, 95% CI 1.945–5.931), BMI ≥ 25 kg/m2 (OR 2.705, 95% CI 1.121–3.889), diabetes (OR 3.049, 95% CI 1.781–5.114), hypertension (OR 2.725, 95% CI 1.108–3.431) and severe hyperplasia (OR 3.181, 95% CI 1.496–4.228) were the risk factors of EC in patients with EH (all P < 0.05). Conclusions The risk of EC in EH patients is high, especially for those patients with age > 50 y, BMI ≥ 25 kg/m2, diabetes, hypertension and severe hyperplasia, special attentions should be paid for occurrence of EC and early diagnosis and early treatment are needed for those patients.

Abstract Background: Mounting evidence have shown that fecal microbiome can act as biomarkers for diagnosing colorectal cancer (CRC). Recent studies demonstrate that oral microbiome is concordant with gut microbiome. The role of oral microbiome in colorectal cancer has not been fully illustrated. Methods: We collected preoperational saliva with a final cohort of 237 patients who underwent surgical resections or colorectal endoscopy in XX Hospital from January 2018 to January 2020. Clinical demographics, comorbidities and oral conditions were obtained from medical records or questionnaires. Salivary microbial biomarkers were detected by quantitative polymerase chain reaction (PCR) after DNA extraction. Multivariate logistics regression analysis was employed to analyze the risk factors for colorectal cancer. A four-variable prediction model was constructed based on the logistics analysis.Results: Among the 237 patients enrolled, there were 95 endoscopy confirmed healthy control and 142 pathologically confirmed colorectal adenocarcinoma patients. Logistics regression analysis demonstrated that the risk factors associated with CRC included age at diagnosis (OR=1.111, 95%CI=1.072-1.151), male sex (OR=2.111, 95%CI=1.068-4.175), oral hygiene index (OR=1.769, 95%CI=1.116-2.804) and relative salivary Desulfovibrio desulfuricans (Dd) abundance (OR=1.156, 95%CI=1.05-1.272), based on which a four-variable model was developed. The four-variable model had good discriminative (Brier score=0.144, Concordance index=0.866) and calibration (0.834) abilities after bias correction. Conclusions: Elevated salivary Dd level is an independent risk factor for CRC. We have developed a four-variable model that could help identify at-risk patients for CRC.

Introduction: Dengue virus (DENV) affects over half the world’s population in 112 countries, and dengue fever (DF) is the second largest arthropod borne infectious global hazard after malaria with complications like Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS) accounting for significant morbidity and mortality world over. Pakistan is significantly affected with DENV infection and to-date no study identifying risk factors associated with complications of DF has been done. Methods: 997 confirmed cases of DF were collected in a tertiary care hospital in Lahore, Pakistan and their clinical and biochemical data were collected. Univariate, multivariate and logistics regression analysis was performed to identify risk factors associated with development of DHF and DSS. Results: Bleeding OR 70.7 (CI 38.4-129.9), deranged liver function test OR 1.9 (CI 0.97-0.99), platelet count on admission less than 50,000 x109/L OR 0.16 (CI 0.13-0.19), presence of urinary red blood cells OR 1.4 (CI 0.179-0.900) and presence of urinary protein OR 1.1 (CI 0.191-0.974) were related to development of DHF and DSS.

Background:SSc characterized by varying degrees of fibrosis of the skin and internal organs, clinicians pay more attention to skin and viscera conditions, tend to ignore hematologic system damage. Studies have shown that rheumatic disease such as SLE, RA, pSS often accompanied with hematologic system damages, and hematologic system damages is multiple organ involvement and risk factor of poor prognosis[1-2].Objectives:To investigate the the clinical features, laboratory characteristics and risk factors of Systemic Sclerosis (SSc) patient with hematologic system damages.Methods:The clinical data of 180 patients were collected from January 2010 to April 2020, at the Affiliated Hospital of North Sichuan Medical College. The demographic information, laboratory tests, and clinical symptoms were analyzed retrospectively.Results:Among 180 SSc patients, 70(38.9%) cases were complicated with hematologic system damages. 51(72.9%) cases had anemia, 24 cases (34.3%) had leukopenia, 24 cases (34.3%) had thrombocytopenia, and 22 cases had hematologic system damages associated with more than two cell line involvement. Clinical symptoms: arthritis was significantly higher in the hematologic system damages group than patient without (P<0.05), however, there was no significantly difference in gender, age, disease course, respiratory symptoms, gastrointestinal symptoms, Raynaud’s phenomenon, interstitial lung disease and pulmonary hypertension (all P>0.05). Laboratory tests: ESR and hsCRP were increased in the hematologic system damages group, while the albumin decreased (all P<0.05). The positive rates of resistance to anti-dsDNA antibody and anti-ribosomal P protein antibody was higher in the hematologic system damages group (all P<0.05). Prognosis: During follow-up, leukopenia was more likely to recover, while the thrombocytopenia was more difficult to recover. Logistics regression analysis showed that positive of anti-ribosomal P protein antibody maght be a risk factor for SSc complicated with hematologic system damages [OR = 3.930(P<0.05)] (Table 1).Conclusion:SSc complicated with hematologic system damages is common, and patients with hematologic system damages have more serious clinical symptoms, some of whom have difficulty in recovey. Anti-ribosomal P protein antibody may be a risk factor of SSc hematologic system damages.Table 1.Bivariate logistics regression analysis on risk factors associated with hematologic damages in SSc.FactorBSEWaldOR(95%CI)P valuearthritis0.6540.3473.5431.922(0.973-3.797)0.060ESR-0.0810.4870.0280.922(0.355-2.393)0.868hsCRP-0.0070.4920.0000.993(0.379-2.607)0.989anti-dsDNA0.8680.6731.6642.393(0.637-8.916)0.197anti-Rib-P1.3690.6364.6333.930(1.130-13.666)0.031References:[1]González-Naranjo L A, Betancur O M, Alarcón G S, et al.

Abstract Objectives To summarize and analyze the clinical characteristics of postoperative complications after minimally invasive closure of transthoracic ventricular septal defect, and to explore the risk factors for its occurrence. Methods Retrospectively analyzed the clinical data of 209 patients underwent transthoracic ventricular septal defect closure performed in the Department of Cardiothoracic Surgery, Children’s Hospital of Chongqing Medical University from January 2018 to January 2020, obtained relevant clinical data from the electronic medical record system and summarized their postoperative complications. And used univariate logistics regression and multivariate logistics regression to analyze the risk factors of its occurrence. Results The postoperative hospital stay of 27 patients was longer than 9 days. Residual shunt occurred in 33 patients recently after operation. One patient underwent surgical treatment again because of mechanical hemolysis after the operation. Two patients were re-operated 1 month and 10 months after surgery because of persistent moderate to severe aortic regurgitation. After surgery, 3 patients underwent pericardiocentesis due to a large amount of pericardial effusion, and 2 patients developed a new atrioventricular block after the operation. No other serious adverse events occurred. Multivariate logistic regression analysis showed that the size of VSD defect (OR: 1.494, 95% Cl: 1.108–2.013, P value: 0.008) was related to long postoperative hospitalization. The residual shunt is related to the size of the occluder (OR: 1.452, 95%Cl: 1.164–1.810, P value: 0.001). In the univariate logistics regression analysis, no risk factors related to serious adverse events were found. Conclusions The minimally invasive closure of transthoracic ventricular septal defect is very effective, with no mortality and low incidence of serious adverse events after surgery. The size of the defect is related to the long postoperative hospitalization, and the size of the occluder is related to the residual shunt in the early postoperative period. No risk factors related to the occurrence of serious adverse events after the operation were found.

Background: Tracheobronchial foreign body aspiration (TFBA) is a major cause of death in children. There are few reports about lower respiratory tract infection (LRTI) caused by TFBA. This study collected the TFBA in our hospital to analyze the LRTI and to determine its risk factors. Methods: A total of 194 children who were performed TFBA extraction in The Children’s Hospital of Zhejiang University School of Medicine between June 2019 and April 2020 were enrolled. The clinical data, cervicothoracic CT and operation records were collected. Chi-square test, rank sum test and multivariate logistics regression analysis were applied. Results: The incidence of LRTI was 46.6%, 68.6% and 68.6% respectively when retention time was within 24 hours, 1 week and more than 1 week. Cervicothoracic CT showed embedding site in and above trachea in 24 cases, in main bronchus in 134 cases, in segmental bronchus and below in 36 cases. Cervicothoracic CT showed no obvious abnormality in 60 cases, obstructive emphysema or atelectasis in 77 cases, obstructive pneumonia in 50 cases, and the rest in 7 cases. Cervicothoracic CT diagnosis and retention time of TFBA were different between LRTI group and non-LRTI group in univariate analysis. There was a correlation between the retention time of TFBA and LRTI in multivariate logistics regression analysis. Conclusionss: The incidence of LRTI caused by TFBA is high. There was no difference in the incidence of LRTI between organic and inorganic TFBA. The retention time of TFBA is an independent risk factor for LRTI.
