Public Attitudes Toward Anxiety Disorder on Sina Weibo: Content Analysis.

BACKGROUND: Anxiety disorder has become a major clinical and public health problem, causing a significant economic burden worldwide. Public attitudes toward anxiety can impact the psychological state, help-seeking behavior, and social activities of people with anxiety disorder. OBJECTIVE: The purpose of this study was to explore public attitudes toward anxiety disorders and the changing trends of these attitudes by analyzing the posts related to anxiety disorders on Sina Weibo, a Chinese social media platform that has about 582 million users, as well as the psycholinguistic and topical features in the text content of the posts. METHODS: From April 2018 to March 2022, 325,807 Sina Weibo posts with the keyword "anxiety disorder" were collected and analyzed. First, we analyzed the changing trends in the number and total length of posts every month. Second, a Chinese Linguistic Psychological Text Analysis System (TextMind) was used to analyze the changing trends in the language features of the posts, in which 20 linguistic features were selected and presented. Third, a topic model (biterm topic model) was used for semantic content analysis to identify specific themes in Weibo users' attitudes toward anxiety. RESULTS: The changing trends in the number and the total length of posts indicated that anxiety-related posts significantly increased from April 2018 to March 2022 (R2=0.6512; P<.001 to R2=0.8133; P<.001, respectively) and were greatly impacted by the beginning of a new semester (spring/fall). The analysis of linguistic features showed that the frequency of the cognitive process (R2=0.1782; P=.003), perceptual process (R2=0.1435; P=.008), biological process (R2=0.3225; P<.001), and assent words (R2=0.4412; P<.001) increased significantly over time, while the frequency of the social process words (R2=0.2889; P<.001) decreased significantly, and public anxiety was greatly impacted by the COVID-19 pandemic. Feature correlation analysis showed that the frequencies of words related to work and family are almost negatively correlated with those of other psychological words. Semantic content analysis identified 5 common topical areas: discrimination and stigma, symptoms and physical health, treatment and support, work and social, and family and life. Our results showed that the occurrence probability of the topical area "discrimination and stigma" reached the highest value and averagely accounted for 26.66% in the 4-year period. The occurrence probability of the topical area "family and life" (R2=0.1888; P=.09) decreased over time, while that of the other 4 topical areas increased. CONCLUSIONS: The findings of our study indicate that public discrimination and stigma against anxiety disorder remain high, particularly in the aspects of self-denial and negative emotions. People with anxiety disorders should receive more social support to reduce the impact of discrimination and stigma.

Using cross efficiency method integrating regret theory and WASPAS to evaluate road safety performance of Chinese provinces.

Currently, the road safety performance of a national- or province-level is absorbing much attention from practitioners and academics. A variety of models based on Data Envelopment Analysis (DEA) have been presented to appraise road safety performance in previous literature. However, the main weakness of these methods is that the decision-maker's psychological behavior is neglected. Besides, Cross Efficiency Method (CEM) adopts the weighted average to aggregate the cross efficiencies which may lead to information loss. To address these limitations, a hybrid road safety evaluation model was constructed by integrating CEM, regret theory, and Weighted Aggregated Sum Product Assessment (WASPAS) to appraise the road safety performance of Chinese provinces. In the presented model, regret theory is employed to depict the psychological behavior of the decision-maker. Then entropy weight method is utilized to calculate the weight of self-evaluation and peer-evaluation. To reduce information loss, WASPAS is adopted to fuse the cross efficiencies and derive the ranking of decision-making units. Finally, the presented model is employed to assess the road safety efficiency in the province of mainland China. The results show that the mean of road safety efficiency score for the eastern, central, and western areas is gradually decreasing. Furthermore, the outcomes of a comparative analysis represent that the results obtained by the proposed model outperform the CEM and DEA road safety model.

Percutaneous transhepatic cholangiography and drainage and endoscopic retrograde cholangiopancreatograph for hilar cholangiocarcinoma: which one is preferred?

INTRODUCTION: both percutaneous transhepatic cholangiography and drainage (PTCD) and endoscopic retrograde cholangiopancreatography (ERCP) with SEMS implantation have been used for unresectable hilar cholangiocarcinoma (HC) in the clinic for many years. However, which one is preferred is still unknown. OBJECTIVE: to study the effects of biliary drainage of self-expanding metal stents (SEMS) implantation under PTCD or ERCP to treat HC. METHODS: the clinical data of 82 patients with HC from January 2006 to January 2015 were recorded retrospectively. Patients were treated with biliary implantation of self-expanding metal stents (SEMS) under PTCD (PTCD group, 40 patients) or ERCP (ERCP group, 42 patients). Clinical data, including total bilirubin concentrations, complications and survival time were analyzed. RESULTS: the remission of jaundice was similar in both groups (p > 0.05). The median survival time of the ERCP group and PTCD group were 237 d and 252 d respectively, with no significant differences (p > 0.05). The biliary infection rates under ERCP and PTCD procedure were 52.4 % and 20.0 % respectively, with a significant statistical difference (p < 0.05). For those HC patients of Bismuth III/IV, the infection rates under ERCP and PTCD procedure were 58.3 % and 14.3 %, respectively (p < 0.05). CONCLUSIONS: both PTCD and ERCP with SEMS implantation were effective to prolong the survival time of HC patients. The biliary infection rates were higher in the ERCP group, especially for Bismuth III/IV HC patients

Characteristics of vascular supply to uterine leiomyoma: an analysis of digital subtraction angiography imaging in 518 cases.

OBJECTIVES: To investigate the characteristics of the vascular supply to uterine leiomyomas based on digital subtraction angiography. METHODS: The feeding artery, vascularity of uterine leiomyoma and visualisation of the ovarian vessel network were studied in 518 patients undergoing uterine artery embolisation (UAE). Mean patient age was 38.97 ± 6.09 years (range, 22-54 years). The types of vascular supply were analysed by the vascular supply to the leimyoma and grades of vascularity by the degree of enhancement of the leimyoma compared with the myometrium. RESULTS: The blood supply of leiomyomas could not be classified in 3.28 % of patients. Blood was supplied solely by the uterine artery in 88.61 % of leiomyomas, 8.11 % of leiomyomas were partially fed by an ovarian artery, and 0.39 % by it exclusively. Leiomyoma blood supply was classified as unilateral predominant, bilateral balanced, single unilateral uterine artery and single ovarian artery in 36.48, 49.23, 10.62 and 0.39 % of cases respectively. Leiomyoma vascularity was classified as extremely hypervascular (8.69 %), hypervascular (46.14 %), isovascular (33.39 %) and hypovascular (11.78 %). CONCLUSIONS: Uterine leiomyomas supplied by both uterine arteries and with rich blood flow were seen in approximately 50 % of patients. However, close attention also should be given to the collateral circulation during UAE.
