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.

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.

This research was completed in 2014, in an attempt to determine the problems and solutions of the irrigation unions and their members who operate in the city of Hatay. The research involves 6 out of 8 irrigation unions located in Hatay. The data was gathered by face to face surveys conducted with 6 union managers and 173 union members. Logistics Regression analysis, which is a multivariate analysis technic was used in the analysis of the variables. It was concluded that 65% of the producers are satisfied, and 35% of them are unsatisfied with the irrigation union. The estimate parameters revealed that the irrigation price at low and normal level were the most effective variables. In accordance with the data, evaluated for the managerial staff in the permanent status, showed that the lack of the efficient and subject expert personnel is one of the most important issues directly interfering with the provided service. The delays occurring in the collection of the price of the irrigation water disrupts the maintenance services needed while operating the facilities. The unions need public assistance to cover the personnel expenses, large maintenance processes, and development of the facilities.

<p>Scarce resources, strict take-back legislations, decreasing life cycle of products and increasing competition are compelled original equipment manufacturers (OEMs) to collect and reuse their returned products. Remanufacturing is a well-known and widely used environment-friendly manufacturing to evaluate product returns. Moreover, with remanufacturing, OEMs offer environment-friendly products to environmentally concerned consumers, also known as green consumer. This study aims to develop a prediction model to determine consumer purchase behavior of remanufactured products. We investigate the data with a survey of closed-end questions conducted among 400 residents of Ankara, Turkey. We consider several factors that influence consumers’ preferences in purchasing process of remanufactured products. The suggested model predicts consumer behavior of remanufactured products with logistic regression analysis. The results show that some factors have effects on consumer purchase behavior of remanufactured product such as low prices, company reliability and product promotion changes consumer behavior from no purchasing to purchasing remanufactured products.</p>

AIM: To compare the incidence of posterior capsule folds among different types of intraocular lens (IOL) to determine risk factors of posterior capsule folds. METHODS: It was a retrospective study. We collected the cases in which the patients underwent phacoemulsification (PHACO) and IOL implantation and at least one of the three types of IOL was implanted, including 2-haptic 3-piece IOLs (HOYA PY60AD), 4-haptic 1-piece IOLs (Bausch&Lomb AO), 2-haptic 1-piece IOLs (AMO Tecnis ZCB00). The posterior capsule folds were measured using slit lamp microscope 2d after the surgery. Information of patient’s age, gender, length of ocular axis, intraocular pressure, types of IOL were recorded. Posterior capsule fold risk indicators were identified by using logistic regression analysis. RESULTS: One hundred eighty-seven patients (242 eyes) had been collected, including 80 eyes implanted with HOYA PY60AD IOLs, 81 eyes implanted with Bausch&Lomb AO IOLs, 81 eyes implanted with AMO Tecnis ZCB00 IOLs. The incidence of posterior capsule folds of patients implanted with HOYA PY60AD IOLs was significantly higher than those of patients implanted with AMO Tecnis ZCB00 IOLs. While the incidence of patients implanted with Bausch&Lomb AO IOLs was significantly lower than those of patients implanted with AMO Tecnis ZCB00 IOLs. Multi-factor logistics regression analysis demonstrated that independent risk factors were type of IOLs and length of ocular axis. Compared with AMO Tecnis ZCB00 IOLs, using HOYA PY60AD IOLs increased the risk of posterior capsule folds [P=0.020, OR (95%CI)=2.145 (1.129, 4.073)], while using Bausch&Lomb AO IOLs reduced the risk [P=0.001, OR (95%CI)=0.274 (0.127, 0.591)]. Shorter ocular axis might increase the risk of posterior capsule folds [P=0.012, OR (95%CI)=0.669 (0.489, 0.915)]. CONCLUSION: Haptic design should be an important consideration in IOL design. Compared with AMO Tecnis ZCB00 IOLs, using HOYA PY60AD IOLs is more likely to lead to posterior capsule folds formation, while using Bausch&Lomb AO IOLs is less likely to lead the formation. The posterior capsule folds are more engendered in eyes with shorter ocular axis.

Abstract Background: The non-HDL cholesterol to HDL cholesterol (NHDLC/HDLC) ratio is closely related to a variety of dyslipidemia-related disease. This study aimed to inspect the relationship between the NHDLC/HDLC ratio and non-alcoholic fatty liver (NAFLD) in childhood and adolescence. Methods: In this cross-sectional survey, a total of 7,759 eligible Chinese children and adolescents (5,692 boys and 2,067 girls) were received routine medical examinations. The anthropometric and laboratory data of the subjects were collected. NAFLD was diagnosed by liver ultrasonography. The binary logistics regression analysis was performed on NHDLC/HDLC ratio, NHDLC and HDLC and NAFLD. ROC curve analysis was exploited to compare the diagnostic significance of the above parameters for NAFLD. Results: The total prevalence of NAFLD was 4.36%, and the prevalence of boys was higher than that of girls (5.61% vs. 1.9%, P < 0.001). The prevalence of NAFLD was positively correlated with the NHDLC/HDLC ratio (P < 0.001). The binary logistics regression analysis demonstrated that the OR was 8.61 (95% CI, 5.90-12.57, P < 0.001) in the tertile 3 (highest NHDLC/HDLC ratio) compared with the tertile 1 (lowest NHDLC/HDLC ratio). When potential confounders (age, sex, BMI, ALT, UA, TB, FPG and HOMA-IR) were adjusted, the OR for the tertile3 (OR=1.83, 95% CI, 1.04-3.22, P = 0.035) was still drastically higher than that of the tertile 1. The AUC of the NHDLC/HDLC ratio of boys was 0.787, which was significantly greater than that of NHDLC and HDLC (0.719 and 0.726, P < 0.001). For girls, the AUC of NHDLC/ HDLC ratio was 0.763, which was also significantly greater than that of NHDLC (0.661, P < 0.001). Furthermore, the cutoff points of NHDLC/HDLC ratio were 2.475 in boys and 2.695 in girls. Conclusions: The NHDLC/HDLC ratio was positively correlated with NALFD in Chinese children and adolescents. It may serve as an effective indicator to help identify NALFD in children and adolescents.

Background: Globally, the incidence of allergic diseases is increasing along with cesarean delivery rates. Data regarding the association between cesarean delivery and allergic diseases are inconsistent. Here, we aimed to clarify the association between cesarean delivery and the development of asthma, atopic dermatitis, wheezing, and eczema. Methods: We used data from the Japan Environment and Children’s Study. The data included were those of 104,065 fetal records and their children. Information about the mode of delivery, asthma, atopic dermatitis, wheezing, and eczema was obtained from questionnaires and medical record transcripts. Multiple logistic regression analysis was used to assess the association between cesarean delivery and asthma, atopic dermatitis, wheezing, and eczema risk among infants at 1 year of age. Results: We included 74,639 subjects in this study, wherein 18.4% underwent cesarean deliveries. After adjusting for the perinatal, socioeconomic, and postnatal confounding factors, children born by cesarean delivery had no increased risk of developing asthma [95% confidence interval (CI) 0.84–1.08], atopic dermatitis (95% CI, 0.92–1.13), wheezing (95% CI, 0.94–1.04), or eczema (95% CI, 0.94–1.05). Conclusions: This nationwide cohort study found no association between cesarean delivery and asthma, atopic dermatitis, wheezing, and eczema among infants at 1 year of age. However, further studies are needed to evaluate whether cesarean delivery plays a role in the development of allergic diseases.
