Background: Although convex-probe endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become a standard procedure for diagnosis of mediastinal disease, including nodal staging for lung cancer, infectious complications are reported occasionally. The aim of this study is to evaluate the rate and risk factors of infectious complications occurring after the procedure. Methods: We retrospectively reviewed 8048 cases of EBUS-TBNA performed at Samsung Medical Center (a 1979-bed referral hospital) between 2009 and 2019. Infectious complications after EBUS-TBNA were defined by clinical features and chest imaging. We randomly selected a control group (2:1) and the risk factors were analyzed using a multivariate logistic regression with backward selection. Results: A total of 33 cases (0.41%) of infectious complication occurred after EBUS-TBNA during the study period; 22 cases (66.7%) with mediastinitis, and 11 (33.3%) with pneumonia. In a multivariate logistic regression analysis including 33 cases of infectious complications and 66 controls, the patients less than 65- year of age (adjusted odds ratio [aOR], 3.63; 95% confidence interval [CI], 1.34-9.80), with a past history of tuberculosis (aOR, 3.61; 95% CI, 1.01-12.89), and cases that underwent transesophageal bronchoscopic ultrasound-guided fine needle aspiration (EUS-B-FNA; aOR, 3.48; 95% CI 1.15-10.52) were associated with significantly higher incidence of infectious complications. Conclusion: EBUS-TBNA rarely causes infectious complications, however a precaution should be considered in young patients with a previous history of tuberculosis or procedure with EUS-B-FNA.
A novel reflectance-based aptasensor using gold nanoparticles for the detection of oxytetracycline

<P>We present a novel reflectance-based colorimetric aptasensor using gold nanoparticles for the detection of oxytetracycline for the first time. It was found that the reflectance-based measurement at two wavelengths (650 and 520 nm) can generate more stable and sensitive signals than absorbance-based sensors to determine the aggregation of AuNPs, even at high AuNP concentrations. One of the most common antibacterial agents, oxytetracycline (OTC), was detected at concentrations as low as 1 nM in both buffer solution and tap water, which was 25-fold more sensitive, compared to the previous absorbance-based colorimetric aptasensors. This reflectance-based colorimetric aptasensor using gold nanoparticles is considered to be a better platform for portable sensing of small molecules using aptamers.</P> <P>Graphic Abstract</P><P>We present a novel reflectance-based colorimetric aptasensor using gold nanoparticles for the detection of oxytetracycline for the first time. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c5an00726g'> </P>
Bilingual Multiword Expression Alignment by Constituent-Based Similarity Score
( Hyeong-won Seo ),( Hongseok Kwon ),( Min-ah Cheon ),( Jae-hoon Kim ) 한국정보처리학회 2016 Journal of information processing systems Vol.12 No.3
This paper presents the constituent-based approach for aligning bilingual multiword expressions, such as noun phrases, by considering the relationship not only between source expressions and their target translation equivalents but also between the expressions and constituents of the target equivalents. We only considered the compositional preferences of multiword expressions and not their idiomatic usages because our multiword identification method focuses on their collocational or compositional preferences. In our experimental results, the constituent-based approach showed much better performances than the general method for extracting bilingual multiword expressions. For our future work, we will examine the scoring method of the constituent-based approach in regards to having the best performance. Moreover, we will extend target entries in the evaluation dictionaries by considering their synonyms.
