RESUMO
Objective: To explore the influencing factors of the adverse outcome of pulmonary tuberculosis (PTB) among adolescents in Hangzhou City between 2005 and 2020. Methods: A retrospective cohort study was used to collect the information of adolescent PTB patients with the onset of PTB occurring from January 1, 2005 to December 31 in 12 designated tuberculosis hospitals in Hangzhou, mainly including demographic, epidemiological, clinical manifestations, bacteriological characteristics and other data, through the China Management Information System for Infectious Disease Surveillance and Reporting and the follow-up survey. All patients were followed up and the end time was December 31, 2021. Multivariate Cox regression model was used to analyze the factors affecting the adverse outcome of these patients. Results: The mean age of 4 921 adolescent PTB patients was (18.9±3.6) years old, and the number of male and female patients were 3 074 and 1 847 respectively. The adverse outcome accounted for 14.7% (725) of all patients. Multivariate Cox regression model showed that eight risk factors, including management model from patients themselves or family members (HR=5.87, 95%CI: 4.55-7.64), molecular biology examination positive for PTB (HR=4.62, 95%CI: 2.98-7.19), the number of sputum smears-positive≥1 (HR=3.72, 95%CI: 2.87-4.83), non-standardized therapy regimens of PTB (HR=3.69, 95%CI: 2.95-4.64), history of retreated PTB (HR=2.22, 95%CI: 1.46-3.36), migrant adolescents (HR=1.89, 95%CI: 1.54-2.34), the number of chest X-ray scan (HR=1.83, 95%CI: 1.65-2.04), and severe PTB (HR=1.38, 95%CI: 1.02-2.05), were associated with the adverse outcome of adolescent PTB patients. Age (HR=0.94, 95%CI: 0.92-0.96), as the only protective factor, was associated with the adverse outcome of these patients. Conclusion: The management mode, molecular biological examination, chemotherapy program, history of tuberculosis, sputum smear examination, severity of tuberculosis, household residence, chest X-ray examination and age are associated with the adverse outcomes of adolescent PTB patients in Hangzhou.

OBJECTIVE: Postpartum hemorrhage (PPH) is a major cause of maternal mortality and morbidity worldwide. The purpose of this study was to evaluate if meconium-stained amniotic fluid (MSAF) is a risk factor for PPH after vaginal delivery. PATIENTS AND METHODS: We retrospectively analyzed medical records of all patients who had a vaginal delivery at Fujian Provincial Maternity and Children's Hospital, between 1st January 2013 to 31st December 2018. Women with cesarean deliveries, multiple pregnancies, abnormal coagulation profile, and those with concomitant liver or kidney disorders were excluded. Patients were classified into MSAF (n=13686) and clear amniotic fluid (AF) (n=41511) groups. RESULTS: The incidence of PPH was significantly higher at 2.7% (370/13686) in the MSAF group as compared to 2.18% (904/41511) in the clear AF group (p=0.0004). There was no difference in the incidence of severe PPH between the two groups. Statistically significant difference in the incidence of PPH between MSAF and clear AF was seen in the maternal age groups of 30-34 and 35-39 years, gestational age>40weeks and >3 gravidity (p<0.05). CONCLUSIONS: Our study demonstrates that MSAF is a significant risk factor for minor and moderate PPH. Presence of meconium could therefore alert clinicians to expect PPH and make arrangements for further patient management. Further basic research is required to evaluate the mechanism by which meconium influences the incidence of PPH.

AIM: To investigate the gene susceptibility of bladder cancer and potential relation with smoking. METHODS: An analysis of SNPs were conducted among DNA repair genes of XPC, XPG, XRCC1, and six members of metabolic enzyme gene CYP 450 via TaqMan Probe-based polymerase chain reaction. A total of 130 patients with bladder cancer and 304 healthy controls were involved. RESULTS: Polymorphisms of XPC gene was related to bladder cancer. It was also related to smoking status in bladder cancer patients, as well as to tumour stage, male gender and older age. The XPG gene polymorphism was also related to bladder cancer yet it was prevalent in female non-smokers. No association was acquired for XRCC1 gene. The combination of more than 2 polymorphisms in DNA repair genes was associated with bladder cancer. No association was obtained in any of the metabolic enzyme gene of CYP450 with either bladder cancer or smoking status. CONCLUSION: DNA repair genes XPC and XPG could be related to carcinogenesis and tumour progression of bladder cancer. Confirmation within larger population was warranted.

AIMS: Stage Ta/T1 urothelial carcinoma of the bladder (Ta/T1 BC) has a marked tendency to recur. Regenerating protein 1 A (REG1A) has been reported to be expressed in human cancers, and it may be positively correlated with patient's prognosis. The aim of the present study was to evaluate the prognostic value of REG1A in Ta/T1 BC. METHODS: Immunohistochemistry was done on 110 paraffin-embedded specimens of human Ta/T1 BC to detect the proteins REG1A, PCNA and MMP2. The relationships between REG1A expression and the clinical-pathological characteristics of Ta/T1 BC patients were evaluated. RESULTS: Sixty-five out of 110 specimens were REG1A-positive. Grade and expression levels of MMP2 and REG1A were significantly correlated with the recurrence rate. REG1A expression (Hazard ratio: 3.1; 95% CI: 1.1-8.5; P=0.030) was an independent predictor of recurrence rate in multivariate Cox regression analysis. A significant association between REG1A expression and MMP2 expression (P=0.023) was also observed. CONCLUSION: Expression of REG1A is an independent predictor of recurrence in Ta/T1 BC.
