Neural epidermal growth factor-like 1 protein-related membranous nephropathy complicated with moyamoya syndrome: a case report and literature review / 中华肾脏病杂志

Except for IgA nephropathy, membranous nephropathy (MN) is the most common primary glomerulonephritis in China. Neural epidermal growth factor-like 1 protein (NELL-1) has been currently considered as one of the target antigens for diagnosis of primary MN. Moyamoya syndrome is a syndrome with clinical and imaging manifestations of moyamoya disease and possible vascular stenosis. By far, primary MN complicated with moyamoya syndrome has not been reported internationally. The paper reports a case of NELL-1-related MN complicated with moyamoya syndrome and reviews relevant literature to provide evidence for clinical diagnosis and treatment.

Construction of an air quality health index for pediatric respiratory diseases in Shanghai / 环境与职业医学

Background Air quality health index (AQHI) has been widely used to quantify the health effects of multiple pollutants observed in population-based epidemiological studies, and can better reflect the widespread linear non-threshold between air pollution and health effects. Objective To explore an AQHI for pediatric respiratory diseases (AQHIr) in Shanghai and evaluate its feasibility. Methods The daily numbers of hospital outpatient visits for pediatric respiratory diseases from 2015 to 2019 were obtained from five general hospitals in Xuhui, Baoshan, Hongkou, Jinshan, and Chongming Districts of Shanghai. Monitoring data on air pollutants (PM2.5, PM10, SO2, NO2, and O3), air quality index (AQI), and meteorological variables (temperature, relative humidity, air pressure, and wind speed) were collected from five air quality monitoring sites nearest to selected hospitals. Time-series analysis using generalized additive model (GAM) was conducted to estimate the associations between respiratory-related pediatric outpatient visits and the concentrations of air pollutants. The sum of excess risk (ER) of hospital outpatient visits was used to construct AQHIr. To assess the predictive power of AQHIr, the associations of AQHIr and AQI with the number of pediatric respiratory outpatient visits in three hospitals in Xuhui, Hongkou, and Chongming districts were compared. Results Air pollutants had various effects on respiratory diseases outpatient visits. PM2.5, NO2, and O3 had most significant impacts on lag0 day and the associated ERs of hospital outpatient visits for each 10 μg·m−3 increase in pollutant concentration were 1.27% (95%CI: 0.88%-1.66%), 0.75% (95%CI: 0.40%-1.11%), and 0.36% (95%CI: 0.10%-0.62%), respectively. PM10 and SO2 had most significant impacts on lag3 day and the associated ERs of hospital outpatient visits for each 10 μg·m−3 increase in pollutant concentration were 0.81% (95%CI: 0.51%-1.12%) and 5.64% (95%CI: 3.37%-7.96%), respectively. There were significant effects of combinations of two pollutants among PM2.5, PM10, NO2, SO2, and O3 except for PM10+NO2, SO2+PM2.5, and SO2+NO2 (P<0.05). According to the results of single-pollutant and two-pollutant models, PM2.5, NO2, SO2, and O3 were selected to construct AQHIr. The comparison showed that for every interquartile range increase in AQHIr, the ER for pediatric outpatient visits was higher than that for the value corresponding to AQI. Conclusion Air pollutants in Shanghai have an impact on the number of pediatric respiratory outpatient visits. The AQHIr based on and outpatient visits for pediatric respiratory diseases can be a sensitive index to predict the effects of air pollution on children's respiratory health.

Efficacy of Solifenacin in the treatment of overactive bladder syndrome after transurethral resection of the prostate / 中华泌尿外科杂志

Objective To evaluate the efficacy and safety of solifenacin in the treatment of overactive bladder (OAB) syndrome in patients who have undergone transurethral resection of the prostate (TURP). Methods According to the Overactive Bladder Symptom Score (OABSS), 64 cases with OAB symptoms after TURP were randomly assigned into study and control groups with 32 cases in each group. Patients in the study group were treated with solifenacin (5 mg once daily) for a two week period beginning the first day after catheter removal. Patients in the control group were not treated with solifenacin. The mean urgency episodes, micturition episodes, nocturia, urge incontinence, volume voided per micturition, Qmax and OABSS scores were recorded on the 7th and the 14th day after catheter removal. Treatment-emergent adverse events with solifenacin in the study group were recorded and evaluated as well. All cases were followed-up for 8 weeks after catheter removal. Results There were statistically significant differences (P<0.01) in favor of the study group over the control group in the aspect of urgency, micturition episodes, nocturia, urge incontinence, volume voided per micturition and OABSS scores. The incidences of treatment related adverse events were 12.5% (4/32) in the study group with no serious adverse event observed. Conclusions Solifenacin is effective in the treatment of OAB syndrome after TURP and is well tolerated as well. Application of solifenacin should be recommended earlier after TURP.
