Influence of Tiapride and Topiramate on Tic Severity and Behavioral/Emotional Problems in Children with Tourette Syndrome: A Retrospective Study.

OBJECTIVES: To investigate the effect of tiapride and topiramate on patients with Tourette syndrome (TS). METHODS: This retrospective analysis included 126 children diagnosed with TS at Children's Hospital of Chongqing Medical University from 2019 to 2021, with treatment including tiapride (n = 60) and topiramate (n = 66). Their tic severity values were assessed with the Yale Global Tic Severity Scale (YGTSS). Furthermore, behavioral and emotional problems were assessed with the Conner's Parent Rating Scale (CPRS) and the Children Behavior Checklist (CBCL). RESULTS: Compared with premedication, the scores of tic severity were significantly decreased in both tiapride and topiramate groups after treatment, especially topiramate. Moreover, it was noted that five subscores of CPRS were significantly reduced in TS patients thanks to medication. However, there was no significant difference in CBCL after treatment, in both tiapride and topiramate groups. CONCLUSIONS: Tiapride and topiramate were proven to be effective on tics and some behavioral/emotional problems in TS patients, and topiramate may provide better treatment.

Activation of the AKT/GSK-3ß/ß-catenin pathway via photobiomodulation therapy promotes neural stem cell proliferation in neonatal rat models of hypoxic-ischemic brain damage.

Background: Hypoxic-ischemic brain damage (HIBD) significantly affects neurodevelopment in infants and is a leading cause of severe neurological morbidity and mortality in neonates. Our previous study found that photobiomodulation therapy (PBMT) improves the impaired spatial learning and memory of HIBD rat models. However, the neuroprotective mechanism conferred by PBMT in HIBD is unclear. Methods: In the present study, HIBD model rats were treated with PBMT at 5 mW/cm2 per day in the dark for 14 days (10 min each day), and primary neural stem cells (NSCs) after oxygen-glucose deprivation (OGD) were treated with PBMT for 10 min at 1, 5, 10, and 20 mW/cm2 in the dark. PBMT promoted hippocampal neural stem cell (NSC) proliferation in vivo and in vitro. Results: Mechanistically, PBMT upregulated phosphatidylinositol 3 kinase (PI3K), phosphorylated protein kinase B (p-AKT), phosphorylated glycogen synthase kinase 3 beta (p-GSK-3ß), ß-catenin, and cyclin D1 expression in vivo and in vitro, promoting NSC proliferation. Furthermore, both LY294002 (a PI3K inhibitor) and IWR-1 (a Wnt/ß-catenin inhibitor) inhibited the PBMT promotion of NSC proliferation after OGD and suppressed ß-catenin and cyclin D1 expression in vitro. Conclusions: PBMT improved the spatial learning and memory of HIBD rats and promoted hippocampal NSC proliferation through the AKT/GSK-3ß/ß-catenin pathway.

Seasonality and Trend Forecasting of Tuberculosis Incidence in Chongqing, China.

Tuberculosis (TB) is a global infectious disease and one of the ten leading causes of death worldwide. As TB incidence is seasonal, a reliable forecasting model that incorporates both seasonal and trend effects would be useful to improve the prevention and control of TB. In this study, the X12 autoregressive integrated moving average (X12-ARIMA) model was constructed by dividing the sequence into season term and trend term to forecast the two terms, respectively. Data regarding the TB report rate from January 2004 to December 2015 were included in the model, and the TB report data from January 2016 to December 2016 were used to validate the results. The X12-ARIMA model was compared with the seasonal autoregressive integrated moving average (SARIMA) model. A total of 383,797 cases were reported from January 2004 to December 2016 in Chongqing, China. The report rate of TB was highest in 2005 (151.06 per 100,000 population) and lowest in 2016 (72.58 per 100,000 population). The final X12-ARIMA model included the ARIMA (3,1,3) model for the trend term and the ARIMA (2,1,3) model for the season term. The SARIMA (1,0,2) * (1,1,1)12 model was selected for the SARIMA model. The mean absolute error (MAE) and mean absolute percentage error (MAPE) of fitting and predicting performance based on the X12-ARIMA model were less than the SARIMA model. In conclusion, the occurrence of TB in Chongqing is controlled, which may be attributed to socioeconomic developments and improved TB prevention and control services. Applying the X12-ARIMA model is an effective method to forecast and analyze the trend and seasonality of TB.

Predicting trend of early childhood caries in mainland China: a combined meta-analytic and mathematical modelling approach based on epidemiological surveys.

Early childhood caries (ECC) is the most common chronic disease in young children. A reliable predictive model for ECC prevalence is needed in China as a decision supportive tool for planning health resources. In this study, we first established the autoregressive integrated moving average (ARIMA) model and grey predictive model (GM) based on the estimated national prevalence of ECC with meta-analysis from the published articles. The pooled data from 1988 to 2010 were used to establish the model, while the data from 2011 to 2013 were used to validate the models. The fitting and prediction accuracy of the two models were evaluated by mean absolute error (MAE) and mean absolute percentage error (MAPE). Then, we forecasted the annual prevalence from 2014 to 2018, which was 55.8%, 53.5%, 54.0%, 52.9%, 51.2% by ARIMA model and 52.8%, 52.0%, 51.2%, 50.4%, 49.6% by GM. The declining trend in ECC prevalence may be attributed to the socioeconomic developments and improved public health service in China. In conclusion, both ARIMA and GM models can be well applied to forecast and analyze the trend of ECC; the fitting and testing errors generated by the ARIMA model were lower than those obtained from GM.

Prevalence and care index of early childhood caries in mainland China: evidence from epidemiological surveys during 1987-2013.

Early childhood caries (ECC) is the most common chronic disease in young children. Its reported prevalence varies greatly across China. This systematic review aimed to explore the epidemiological characteristics of ECC in mainland China from 1987 to 2013. In total, 102 articles were included. The pooled national prevalence and care index (ft/dmft%) for ECC were 65.5% and 3.6%, respectively. The overall ECC prevalence declined from 77.9% during 1987-1994 to 56.4% during 2010-2013. The pooled ECC prevalence for children aged 1-6 years was 0.3%, 17.3%, 40.2%, 54.4%, 66.1%, and 70.7%, respectively. There was no significant difference in prevalence between boys (59.1%) and girls (58.9%); and the care index was also similar (8.1% versus 7.7%). Slightly higher ECC prevalence was observed in rural areas (63.5%) compared with urban areas (59.5%) (RR = 1.08, 95% CI: 1.02-1.14); but a much higher care index was reported in urban children (6.0%) than their rural counterparts (1.6%) (RR = 3.68, 95% CI: 2.54-5.35). The 2006-2013 map of ECC prevalence among 5-year-olds showed wide geographic variations across China. Four adjacent provinces, including Sichuan, Chongqing, Hubei, and Shaanxi, constituted the areas with the lowest ECC prevalence in mainland China.
