Background/Purpose Splenic abscess is rare with potentially life-threatening evolution. The aim of this study is to review the clinical features, microbiological etiologies, treatment, and outcomes of patients with splenic abscess. Methods We reviewed the admitted patients with suspected splenic abscess and made the diagnosis of splenic abscess. The clinical characteristics, underlying diseases, treatment course, organism spectra, abscess number and size, therapeutic methods, and clinical outcome at a tertiary medical center in Taiwan over a period of 5 years were analyzed. Results Of 16 patients with splenic abscess, the male to female ratio was 1 : 1. Common presentations were fever (11 patients, 68.7%), diffuse abdominal pain (6 patients, 37.5%), left upper quadrant pain or tenderness (6 patients, 37.5%), and left-sided pleural effusions (8 patients, 50%). Antimicrobial therapy was administered in all patients. Fourteen (87.5%) patients recovered under medical treatment. One (6.2%) patient underwent splenectomy, four (25%) patients performed percutaneous drainage of their splenic abscess, and 11 (68.7%) patients received antimicrobial therapy alone. Conclusion We noted that mortality may be more related to patients with underlying immunodeficiency. Patients with splenic abscesses receiving antimicrobial therapy alone were in a relatively high proportion and got a good prognosis especially in patients with small and multiple abscesses.
The literature on China’s social media foreign propaganda mostly focuses on text-format contents in English, which may miss the real target and the tool for analysis. In this article, we traced 1256 Twitter accounts echoing China government’s #USAVirus propaganda before and after Twitter removed state-linked operations on June 12, 2020. The 3567 tweets with #USAVirus we collected, albeit many written in English, 74% of them attached with a lengthy simplified Chinese text-image. Distribution of the post-creation time fits the working-hour in China. Overall, 475 (37.8%) accounts we traced were later suspended after Twitter’s disclosure. Our dataset enables us to analyze why and why not Twitter suspends certain accounts. We apply the decision tree, random forest, and logit regression to explain the suspensions. All models suggest that the inclusion of a text-image is the most important predictor. The importance outweighs the number of followers, engagement, and the text content of the tweet. The prevalence of simplified Chinese text-images in the #USAVirus trend and their impact on Twitter account suspensions both evidence the importance of text-image in the study of state-led propaganda. Our result suggests the necessity of extracting and analyzing the content in the attached text-image.
A rapid increase of nosocomial vancomycin-resistant enterococci (VRE) from 23.3% in 2009 to 44.5% in 2018 among all the medical centers in Taiwan was found. The aim of the study was to explore the relationship between antimicrobial usage and prevalence of VRE. We conducted the study between January 2010 and December 2019 in a tertiary teaching hospital in Taiwan. Antibiotic consumption was expressed as defined daily doses (DDDs) per 1,000 patient-days (PDs). The trend in antibiotic consumption and VRE prevalence were analyzed by regression analysis with yearly data. Pearson's correlation analysis was used to determine the relationship between antibiotic consumption and the prevalence of VRE. The total consumption of antibiotics increased significantly from 450.6 DDDs/1,000 PDs in 2010 to 520.1 DDDs/1,000 PDs in 2019 (P = 0.013). Positive correlations were found between the prevalence of vancomycinresistant Enterococcus faecium and the consumption of amoxicillin/clavulanate, vancomycin, and carbapenems, which included meropenem (P < 0.05). The increase in total VRE prevalence was significantly correlated with increased consumption of vancomycin and carbapenems, which included meropenem (P < 0.05). This 10-year study in a hospital demonstrated changes in antimicrobial use, which may have affected VRE prevalence in the hospital. We found a rise in nosocomial VRE prevalence was associated with the use of specific antimicrobial agents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
