Prevalence and risk factors of Helicobacter pylori infection among children in Kuichong Subdistrict of Shenzhen City, China

Background Helicobacter pylori infection is a significant burden to the public health in China as it can lead to various gastric diseases including peptic ulcers and gastric cancer. Since most infections occurred during childhood, it is therefore necessary to understand the prevalence and risk determinants of this bacterial infection in children. Herewith, we conducted a cross-sectional study in the Kuichong Subdistrict of Shenzhen City to assess the prevalence and risk factors of H. pylori infection among children. Methods From September 2018 to October 2018, 1,355 children aged 6–12 years from four primary schools in the Kuichong Subdistrict of Shenzhen City were recruited. These children were screened for H. pylori infection using the 13C-urea breath test. In addition, parents were requested to fill out a standardized questionnaire. The chi-square test and multivariable logistic regression analysis were used to identify risk factors for H. pylori. Results Among 1,355 children recruited in this study, 226 (16.7%; 95% CI [14.7–18.7]) were positive of H. pylori infection. Multivariable logistic regression analysis identified six factors significantly associated with H. pylori infection children including parent(s) with tertiary education level (OR: 0.64; 95% CI [0.46–0.89]), testing bottle feed temperature using the mouth (OR: 1.79; 95% CI [1.19–2.68]), sharing of cutlery between the feeding person and young children during meals (OR: 1.84; 95% CI [1.22–2.78]), eating fruit after peeling (OR: 2.56; 95% CI [1.4–4.71]), frequent dining out (OR: 3.13; 95% CI [1.46–6.68]) and snacking (OR: 1.43; 95% CI [1.01–2.01]). Conclusions Overall, better educated parent(s) played a protective role against the acquisition of H. pylori infection in children. Testing bottle feed temperature using the mouth, cutlery sharing between the feeding person and young children, and snacking posed a lower but significant risk for H. pylori infection. Only eating peeled fruits and frequent dining out were associated with greater infection risks.

Objective We aimed to investigate the relationship of Helicobacter pylori infection with alcohol and smoking. Methods We conducted a cross-sectional study among participants who underwent health check-ups for H. pylori infection between January 2013 and March 2017. We subsequently investigated the relationship of H. pylori infection with alcohol and smoking. Results A total of 7169 participants were enrolled in this study. The overall prevalence of H. pylori infection was 55.2%. Participants with H. pylori infection were more likely to be older than those without H. pylori infection. For male participants with H. pylori infection, multivariable logistic regression analysis indicated that both smoking (odds ratio (OR): 1.61; 95% confidence interval (CI): 1.41–1.83) and alcohol consumption (OR: 1.30; 95% CI: 1.10–1.52) were independently positively associated with H. pylori infection. For female participants, multivariable logistic regression analysis indicated that both smoking (OR: 0.03; 95% CI: 0.02–0.07) and alcohol consumption (OR: 0.20; 95% CI: 0.12–0.33) were inversely significantly associated with H. pylori infection after adjustment for age. Conclusions Smoking and alcohol consumption were risk factors for male participants but these were protective factors for female individuals with H. pylori infection.

e18101 Background: Chemotherapy induced cardiomyopathy is an important complication of some chemotherapeutic agents. The stress of a cancer diagnosis and ongoing chemotherapy may contribute to cardiac morbidity in these patients. The burden of Takotsubo Cardiomyopathy (TCP) in cancer patients is unknown. The incidence of TCP and related outcomes in cancer patients was investigated in this study. Methods: The 2007-2013 National Inpatient Sample (NIS) was analyzed for patients with a prior and new diagnosis of TCP with and without malignancy. Risk factors for mortality were adjusted for associated conditions by multivariable logistic regression analysis. Results: From 2007 through 2013, an estimated 122,750 adults were admitted with a diagnosis of TCP. In 2013, the incidence of admissions in US of patients with coexisting TCP and malignancy was 1.13%. Admissions in 34,957 patients were for a primary diagnosis of TCP with 91.7% females; overall, 665 (2.1%) had solid organ cancer, 237 (0.74%) had hematological malignancy and 354 (1.11%) had metastatic cancer. Patients admitted for TCP with coexisting malignancy had a significantly higher mortality (13.8% vs. 2.9%, p < 0.0001), length of stay (7 vs. 4 days, p < 0.0001) and total charges ($29291 vs. $ 36231, p < 0.0001), compared to those with no malignancy. In patients with a primary diagnosis of TCP and without any underlying malignancy, males had a higher mortality (4.02% vs. 1.03%, p < 0.0001) whereas there was no gender difference in mortality in those with coexisting malignancy (6.25% vs 6.45%, p = 0.965). On multivariable logistic regression analysis, risk factors associated with mortality were solid cancer (OR 3.43, p = 0.008), stroke (OR 18.33, p < 0.0001), venous thromboembolic disease (OR 4.52, p = 0.004), malnutrition (OR 2.41, p = 0.006) and heart failure (OR 1.918, p = 0.004). Conclusions: Outcomes are significantly worse in patients with TCP and solid malignancy. Hence, this patient population must be regarded as high-risk and early diagnostic consideration for TCP is warranted. Early intervention may help lower mortality, decrease resource utilization and reduce the health care costs in these patients.

Retropubic Prostatectomy

Acute kidney injury (AKI) is related to mortality and morbidity. The De Ritis ratio, calculated by dividing the aspartate aminotransferase by the alanine aminotransferase, is used as a prognostic indicator. We evaluated risk factors for AKI after radical retropubic prostatectomy (RRP). This retrospective study included patients who performed RRP. Multivariable logistic regression analysis and a receiver operating characteristic (ROC) curve analysis were conducted. Other postoperative outcomes were also evaluated. Among the 1415 patients, 77 (5.4%) had AKI postoperatively. The multivariable logistic regression analysis showed that estimated glomerular filtration rate, albumin level, and the De Ritis ratio at postoperative day 1 were risk factors for AKI. The area under the ROC curve of the De Ritis ratio at postoperative day 1 was 0.801 (cutoff = 1.2). Multivariable-adjusted analysis revealed that the De Ritis ratio at ≥1.2 was significantly related to AKI (odds ratio = 8.637, p < 0.001). Postoperative AKI was associated with longer hospitalization duration (11 ± 5 days vs. 10 ± 4 days, p = 0.002). These results collectively show that an elevated De Ritis ratio at postoperative day 1 is associated with AKI after RRP in patients with prostate cancer.

Abstract Background: Syphilis infection is one of the most common maternal factors related to stillbirth. The study aims to determine the risk factors for stillbirth among pregnant women infected with syphilis. Methods : This was a retrospective study. Data on stillbirth and gestational syphilis were extracted from the PMTCT program database 2010–2016 in Zhejiang Province. A total of 8724 pregnancy women infected with syphilis were included. Multivariable logistic regression analysis was performed to assess the associations between gestational syphilis and stillbirth. Results : The stillbirth rate among pregnant women infected with syphilis was 1.74% (152/8724) in Zhejiang Province, China, from 2010–2016. Compared with live birth, stillbirth was significantly associated with lower maternal age, not being married, lower gravidity, previous history of syphilis, non-latent syphilis stage, and higher maternal serum titer for syphilis, inadequate treatment for syphilis, and later first antenatal care visit. With multivariable logistic regression analysis, non-latent syphilis (adjusted OR=2.03; 95% CI 1.17–3.53) and maternal titers over 1:4 (adjusted OR=1.78; 95% CI 1.25–2.53) were risk factors for stillbirth. Adequate treatment was the only protective factor for stillbirth (adjusted OR=0.16; 95% CI 0.10–0.25). Conclusions : Adequate treatment is effective in reducing the incidence of stillbirths among pregnant women infected with syphilis, and this is particularly important in women diagnosed with high RPR titer (under 1:4).

Abstract Background: The study was to evaluate initial antimicrobial regimen and clinical outcomes and to explore risk factors for clinical failure (CF) in elderly patients with community-acquired pneumonia (CAP). Methods: 3,011 hospitalized elderly patients were enrolled from 13 national teaching hospitals between January 1, 2014 and December 31, 2014 initiated by the CAP-China network. Risk factors for CF were screened by multivariable logistic regression analysis. Results: The incidence of CF in elderly CAP patients was 13.1%. CF patients were older, longer hospital stays and higher treatment costs than clinical success (CS) patients. The CF patients were more prone to present hyperglycemia, hyponatremia, hypoproteinemia, pleural effusion, respiratory failure and cardiovascular events. Inappropriate initial antimicrobial regimens in CF group were significantly higher than CS group. Undertreatment, CURB-65, PH<7.3, PaO 2 /FiO 2 < 200 mmHg, sodium <130 mmol/L, healthcare-associated pneumonia, white blood cells >10000/mm 3 , pleural effusion and congestive heart failure were independent risk factors for CF in multivariable logistic regression analysis. Male and bronchiectasis were protective factors. Conclusions: Discordant therapy was a cause of CF. Early accurate detection and management of prevention to potential causes is likely to improve clinical outcomes in elderly patients CAP.

AbstractThe role of enlarged subarachnoid space (ESS) in preterm infants has not been described in concrete. We aimed to evaluate whether ESS should be considered a risk factor potentially associated with adverse neurodevelopmental outcomes in prematurity. Electronic medical records of 197 preterm infants (median 32.1 weeks' gestation) including cranial ultrasound (cUS) images, head circumferences, and Korean Developmental Screening Tests for Infants and Children (K-DST) results at 18–24 months corrected age were reviewed. The clinical characteristics and K-DST results were compared in infants with and without ESS (sinocortical width > 3.5 mm). A multivariable logistic regression analysis was performed to identify potential risk factors associated with positive K-DST results. At a median corrected age of 39.0 weeks, 81/197 (41.1%) infants presented ESS. A significantly greater percent of infants in the ESS group screened positive on the K-DST than in the no ESS group (27.2% vs 12.1%, p = 0.007). Within the ESS group, micro-/macrocephaly at term-equivalent age was not different with regard to the K-DST results. From the multivariable logistic regression analysis, gestational age (p = 0.016, OR = 0.855, 95% CI = 0.753–0.971) and ESS (p = 0.019, OR = 1.310, 95% CI = 1.046–1.641) were two significant risk factors associated with positive K-DST results. ESS identified on cUS at term-equivalent age in preterm infants is associated with possible developmental delays. Macrocephaly at term-equivalent age does not guarantee a benign prognosis. Future studies are required to verify ESS as a potential marker for neurodevelopmental delay in preterm infants.

Abstract Background: Many of severe COVID-19 patients are admitted to the hospital or even to the Intensive Care Unit(ICU). The present study was aimed to investigated the risk factors in death from COVID-19.Methods: In this retrospective study, all inpatients confirmed severe or critical COVID-19 from two tertiary hospital in Huangshi were included, who had been discharged or died by March19,2020. Demographic,clinical,treatment,laboratory data and information were extracted from electronic medical records and compared between survivors group and non-survivors group. The univariable and multivariable logistic regression analysis was used to analyze the risk factors associated with in-hospital death.Results: 81 patients were included in this study, of whom 55 were discharged and 26 died in hospital. In all patients, 36(44.4%) patients had comorbidity, including hypertension(27[33.3%]), diabetes(11[13.6%]) and coronary heart disease (CHD)(11[13.6%]), and 16(19.8%) patients accompanied with more than 2 kinds of underlying diseases. The proportion of CHD in non-survivors group was significantly higher than that in survivors group(26.9% vs 7.3%, P=0.032), but there were no differences in hypertension, diabetes and COPD between the non-survivors group and the survivors group. Multivariable logistic regression analysis showed increasing odds of in-hospital death associated with aspartate aminotransferase(AST) and invasive mechanical ventilation (IMV) (P<0.001)(P=0.017）.Conclusions: Invasive Mechanical Ventilation may contribute to mortality of severe/critical COVID-19 pneumonia, and with higher AST at admission was one of the indicators of poor prognosis.Trial registration: Chinese Clinical Trial Registration; ChiCTR2000031494; Registered 02 April 2020; http://www.medresman.org

Background: This study aimed to construct a clinical prediction model for osteosarcoma patients to evaluate the influence factors for the occurrence of lymph node metastasis (LNM).Methods: In our retrospective study, a total of 1,256 patients diagnosed with chondrosarcoma were enrolled from the SEER (Surveillance, Epidemiology, and End Results) database (training cohort, n = 1,144) and multicenter dataset (validation cohort, n = 112). Both the univariate and multivariable logistic regression analysis were performed to identify the potential risk factors of LNM in osteosarcoma patients. According to the results of multivariable logistic regression analysis, A nomogram were established and the predictive ability was assessed by calibration plots, receiver operating characteristics (ROCs) curve, and decision curve analysis (DCA). Moreover, Kaplan-Meier plot of overall survival (OS) was plot and a web calculator visualized the nomogram.Results: Five independent risk factors [chemotherapy, surgery, lung metastases, lymphatic metastases (M-stage) and tumor size (T-stage)] were identified by multivariable logistic regression analysis. What's more, calibration plots displayed great power both in training and validation group. DCA presented great clinical utility. ROCs curve provided the predictive ability in the training cohort (AUC = 0.805) and the validation cohort (AUC = 0.808). Moreover, patients in LNN group had significantly better survival than that in LNP group both in training and validation group.Conclusion: In this study, we constructed and developed a nomogram with risk factors, which performed well in predicting risk factors of LNM in osteosarcoma patients. It may give a guide for surgeons and oncologists to optimize individual treatment and make a better clinical decision.
