| 1 | Evaluation of Doppler-ultrasonography in the diagnosis of transjugular intrahepatic portosystemic shunt dysfunction: A prospective study显示文摘AIM To prospectively evaluate the performance of Dopplerultrasonography(US) for the detection of transjugular intrahepatic portosystemic shunt(TIPS) dysfunction within a multicenter cohort of cirrhotic patients.METHODS This study was conducted in 10 french teaching hospitals. After TIPS insertion, angiography and liver Doppler-US were carried out every six months to detect dysfunction(defined by a portosystemic gradient ≥ 12 mm Hg and/or a stent stenosis ≥ 50%). The association between ultrasonographic signs and dysfunction was studied by logistic random-effects models, and the diagnostic performance of each Doppler criterion was estimated by the bootstrap method. This study was approved by the ethics committee of Tours.RESULTS Two hundred and eighteen pairs of examinations performed on 87 cirrhotic patients were analyzed. Variables significantly associated with dysfunction were: The speed of flow in the portal vein(P = 0.008), the reversal of flow in the right(P = 0.038) and left(P = 0.049) portal branch, the loss of modulation of portal flow by the right atrium(P = 0.0005), ascites(P = 0.001) and the overall impression of the operator(P = 0.0001). The diagnostic performances of these variables were low; sensitivity was < 58% and negative predictive value was < 73%. Therefore, dysfunction cannot be ruled out from Doppler-US. CONCLUSION The performance of Doppler-US for the detection of TIPS dysfunction is poor compared to angiography. New tools are needed to improve diagnosis of TIPS dysfunction. | Charlotte Nicolas Amelie Le Gouge Louis d’Alteroche Jean Ayoub Monica Georgescu Vincent Vidal Denis Castaing Jean-Pierre Cercueil Patrick Chevallier Jerome Roumy Herve Trillaud Louis Boyer Vincent Le Pennec Christophe Perret Bruno Giraudeau Jean-Marc Perarnau STIC-TIPS group | 2017 | World Journal of Hepatology2017,9,27: | 6 |
| 2 | Estimated prevalence and trends in smoking among adolescents in South Korea,2005-2021:a nationwide serial study显示文摘Background Although smoking is classified as a risk factor for severe COVID-19 outcomes,there is a scarcity of studies on prevalence of smoking during the COVID-19 pandemic.Thus,this study aims to analyze the trends of prevalence of smoking in adolescents over the COVID-19 pandemic period.Methods The present study used data from middle to high school adolescents between 2005 and 2021 who participated in the Korea Youth Risk Behavior Web-based Survey(KYRBS).We evaluated the smoking prevalence(ever or daily)by year groups and estimated the slope in smoking prevalence before and during the pandemic.Results A total of 1,137,823 adolescents participated in the study[mean age,15.04 years[95%confidence interval(CI)15.03-15.06];and male,52.4%(95%CI 51.7-53.1)].The prevalence of ever smokers was 27.7%(95%CI 27.3-28.1)between 2005 and 2008 but decreased to 9.8%(95%CI 9.3-10.3)in 2021.A consistent trend was found in daily smokers,as the estimates decreased from 5.4%(95%CI 5.2-5.6)between 2005 and 2008 to 2.3%(95%CI 2.1-2.5)in 2021.However,the downward slope in the overall prevalence of ever smokers and daily smokers became less pronounced in the COVID-19 pandemic period than in the pre-pandemic period.In the subgroup with substance use,the decreasing slope in daily smokers was significantly more pronounced during the pandemic than during the pre-pandemic period.Conclusions The proportion of ever smokers and daily smokers showed a less pronounced decreasing trend during the pandemic.The findings of our study provide an overall understanding of the pandemic's impact on smoking prevalence in adolescents. | Hyoin Shin Sangil Park Hyunju Yon Chae Yeon Ban Stephen Turner Seong Ho Cho Youn Ho Shin Jung U.Shin Ai Koyanagi Louis Jacob Lee Smith Chanyang Min Young Joo Lee So Young Kim Jinseok Lee Rosie Kwon Min Ji Koo Guillaume Fond Laurent Boyer Jong Woo Hahn Namwoo Kim Sang Youl Rhee Jae Il Shin Ho Geol Woo Hyeowon Park Hyeon Jin Kim Yoonsung Lee Man S.Kim Eléa Lefkir Vlasta Hadalin Jungwoo Choi Seung Won Lee Dong Keon Yon Sunyoung Kim | 2023 | World Journal of Pediatrics2023,19,4: | 1 |

| 4 | National trends in alcohol and substance use among adolescents from 2005 to 2021:a Korean serial cross‑sectional study of one million adolescents显示文摘Background Although previous studies have provided data on early pandemic periods of alcohol and substance use in adolescents,more adequate studies are needed to predict the trends of alcohol and substance use during recent periods,including the mid-pandemic period.This study investigated the changes in alcohol and substance use,except tobacco use,throughout the pre-,early-,and mid-pandemic periods in adolescents using a nationwide serial cross-sectional survey from South Korea.Methods Data on 1,109,776 Korean adolescents aged 13–18 years from 2005 to 2021 were obtained in a survey operated by the Korea Disease Control and Prevention Agency.We evaluated adolescents’alcohol and substance consumption prevalence and compared the slope of alcohol and substance prevalence before and during the COVID-19 pandemic to see the trend changes.We define the pre-COVID-19 period as consisting of four groups of consecutive years(2005–2008,2009–2012,2013–2015,and 2016–2019).The COVID-19 pandemic period is composed of 2020(early-pandemic era)and 2021(midpandemic era).Results More than a million adolescents successfully met the inclusion criteria.The weighted prevalence of current alcohol use was 26.8%[95%confidence interval(CI)26.4–27.1]from 2005 to 2008 and 10.5%(95%CI 10.1–11.0)in 2020 and 2021.The weighted prevalence of substance use was 1.1%(95%CI 1.1–1.2)from 2005 to 2008 and 0.7%(95%CI 0.6–0.7)between 2020 and 2021.From 2005 to 2021,the overall trend of use of both alcohol and drugs was found to decrease,but the decline has slowed since COVID-19 epidemic(current alcohol use:βdiff 0.167;95%CI 0.150–0.184;substance use:βdiff 0.152;95%CI 0.110–0.194).The changes in the slope of current alcohol and substance use showed a consistent slowdown with regard to sex,grade,residence area,and smoking status from 2005 to 2021.Conclusion The overall prevalence of alcohol consumption and substance use among over one million Korean adolescents from the early and mid-stage(2020–2021)of the COVID-19 pandemic showed a slower decline than expected given the increase during the prepandemic period(2005–2019). | Sangil Park Hyunju Yon Chae Yeon Ban Hyoin Shin Seounghyun Eum Seung Won Lee Youn Ho Shin Jung UShin Ai Koyanagi Louis Jacob Lee Smith Chanyang Min AbdullahÖzgür Yeniova So Young Kim Jinseok Lee Vlasta Hadalin Rosie Kwon Min Ji Koo Guillaume Fond Laurent Boyer Sunyoung Kim Jong Woo Hahn Namwoo Kim Eléa Lefkir Victoire Bondeville Sang Youl Rhee Jae Il Shin Dong Keon Yon Ho Geol Woo | 2023 | World Journal of Pediatrics2023,19,11: | 0 |
| 5 | Differences in Pandemic-Related Factors Associated with Alcohol and Substance Use among Korean Adolescents:Nationwide Representative Study显示文摘The coronavirus disease 2019(COVID-19)pandemic has raised concerns about the mental health and social well-being of youth,including its potential to increase or exacerbate substance use behaviors[1].Among adolescents,the COVID-19pandemic has resulted in limited face-to-face school contact and thus missed milestones in preventing alcohol and substance use. | Hyunju Yon Sangil Park Jung U Shin Ai Koyanagi Louis Jacob Lee Smith Chanyang Min Jinseok Lee Rosie Kwon Guillaume Fond Laurent Boyer Sunyoung Kim Namwoo Kim Sang Youl Rhee Jae Il Shin Dong Keon Yon Ho Geol Woo | 2023 | Biomedical and Environmental Sciences2023,36,6: | 0 |
