bnormal CNVs (10/84, 11.9%) in the study population. CMA is a promising powerful tool for prenatal diagnosis that may provide valuable data for the accurate assessment of fetal prognosis and the decision of pregnancy continuation during the prenatal clinical counseling.
 In addition to chromosomal abnormalities identified in 21 fetuses by karyotyping, CMA detected additional 10 fetuses with abnormal CNVs (10/84, 11.9%) in the study population. CMA is a promising powerful tool for prenatal diagnosis that may provide valuable data for the accurate assessment of fetal prognosis and the decision of pregnancy continuation during the prenatal clinical counseling.
  To investigate the incidence and clinical characteristics of hospitalized children with respiratory syncytial virus (RSV) infection, and to provide evidence for the importance of preventive strategies and improvements in supportive care of RSV infection.
 
  This retrospective study included children under 14 years who received throat swab test and were diagnosed with RSV infection from January 2019 to December 2020. Throat swabs and intravenous blood were the main sources of samples, which were obtained within 24 hours of hospitalization. Direct immunofluorescence assay was used to diagnose RSV infection.
 
  Among the 448 hospitalized children with RSV infection, males (71.9%) showed the highest proportion, the highest incidence was found in children<6 months old (45.3%), and 76.6% of them had pneumonia. Pharyngeal redness, cough, expectoration, and mental fatigue were the most common symptoms in hospitalized children of all ages. More than 60% of hospitalized children had increased lymphocyte count, asparion.
 This study analyzes the incidence and clinical characteristics of hospitalized children with RSV infection, which provides evidence for the importance of preventive strategies and improvements in supportive care of RSV infection.
  Understanding the relationship between tourists' consumption behavior and their willingness to substitute consumption in unusual environments can promote tourists' sustainable consumption behavior. This study explores the internal relationship between tourists' willingness to engage in sustainable consumption behavior and the substitution of tourism consumption willingness in an unusual environment and the related factors.
 
  Through qualitative and quantitative mixed research, this study first invited 32 interviewees related to the tourism industry to conduct in-depth and focus group interviews and extracted a research model based on the push-pull theoretical model (PPM) through three rounds of coding of grounded theory. Then, through questionnaire design, pre-release, and formal release, 268 valid questionnaires were collected using a convenience sampling method, and the hypothesis and its mediating effect were verified using a structural equation model.
 
  Further quantitative analysis and verification shoaction mechanism model aimed at guiding tourists' willingness for sustainable consumption, based on the environment and consumption behavior, and provided relevant countermeasures for the government and business decision-makers, enterprises, and investors in the tourism sector.
  On the basis of stimulus-organism-response (SOR) theory, this study extends the work of Lee and Kwon by examining the concept of perceived usefulness as a mediator between emotional interaction (familiarity and intimacy) and purchase intention. The consumer purchase decision model, in which product type plays a moderating role in the linking mechanism, is also explored.
 
  We proposed a consumer purchase decision model, and empirically examined it by means of an online questionnaire survey. Confirmatory factor analysis and structural equation modeling with bootstrapping estimation were conducted using the data obtained from 269 social commerce users.
 
  Familiarity and intimacy positively affected the users' purchase intention in social commerce.  https://www.selleckchem.com/products/liraglutide.html  Perceived usefulness mediated the relationship between emotional interaction and purchase intention. Moreover, product type moderated the following relationships between familiarity and purchase intention, between intimacy and purchase intention, and between perceived usefulness and purchase intention.
 
  The results support this study's hypotheses and SOR theory. Purchase intention could be enhanced by improving emotional interaction and perceived usefulness.

  The objective of this study is to determine if EM resident physicians are able to successfully utilize POCUS to perform an arthrocentesis in the ED. This is a retrospective review of ED patients who received an ultrasound-guided or ultrasound-assisted arthrocentesis performed in the ED over a 6-year period by an EM resident physician.
 
  This was a retrospective review of ED patients who received an ultrasound-guided or ultrasound-assisted arthrocentesis performed in the ED over a 6-year period by an EM resident physician. An ED POCUS database was reviewed for POCUS examinations where an arthrocentesis was performed. Electronic medical records were then reviewed for demographic characteristics, history, physical examination findings, ED course, additional imaging studies, and the impact of the POCUS study on patient care and disposition.
 
  A total of 101 POCUS examinations of patients were included in the final analysis. The POCUS examinations and procedures were performed by 59 different EM residents at varsignificant impact on outcomes and patient care.Chronic hepatitis D virus infection is the most severe form of viral hepatitis. Antiviral treatment is urgently needed to prevent patients from developing end stage liver disease or hepatocellular carcinoma. Treatment options were limited to off-label use of pegylated interferon alfa until conditional approval of bulevirtide by the EMA (European Medicines Agency) in July 2020. However, several other antiviral compounds are currently investigated and represent promising agents for the treatment of chronic HDV infection.
