Background Although the rapid response system is widely spreading, many of them are operated without a dedicated staff. We investigated the changes in emergency airway management by rapid response team (RRT) after a dedicated intensivist staffing. Methods A single-center retrospective non-interventional study was performed at a tertiary hospital. Patients who required emergency airway management by RRT between January 2015 and December 2019 were included. We divided the study period into two eras, non-staff-led (from January 2015 to February 2018, n=971) and staff-led (from March 2018 to December 2019, n=651), and compared variables related to airway management. Results Among 1,622 patients, mean age was 63.0 years and male were 64.2% (n=1,042). Difficult airway was assessed in 306 (18.9%) patients. The first pass success rate was significantly higher (85.9% in the non-staff-led era vs. 89.2% in the staff-led era, p=0.047) and the post-intubation hypoxemia was less common (7.2% vs. 4.2%, p=0.018) in the staff-led era. The ROX index at the time of intubation was higher in the staff-led era (median [interquartile range]; 4.6 [3.4-7.6] vs. 5.1 [3.6-8.5], p=0.013), which suggests the decision for intubation was made earlier. In addition, the use of rapid sequence intubation (9.4% vs. 34.4%, p<0.001) and videolaryngoscope (88.2% vs. 97.1%, p<0.001) were also more frequent in the staff-led era. In multivariate analysis, factors associated with first pass success were the experience of clinician (odds ratio [95% confidence interval]; 2.375 [1.662-3.393], p<0.001 for intensive care unit fellows and 14.316 [1.908-107.415], p=0.010 for RRT staff, relative to internal medicine residents), the use of videolaryngoscope (5.462 [3.428-8.701], p<0.001) and rapid sequence intubation (3.325 [1.839- 6.012], p<0.001), and difficult airway (0.331 [0.224-0.489], p<0.001). Conclusions A dedicated intensivist staffing to RRT was associated with improved emergency airway management in general ward.

Background The shortage of available donor lungs is a continuing clinical problem. Lobar lung transplantation and the extension of donor lung criteria may expand the pool of donor lungs. Methods Medical records of an index patient were retrospectively reviewed with related literatures. Results A 48-year-old female diagnosed with idiopathic pulmonary arterial hypertension was listed for lung transplantation, but no donor lungs were available for 2 years and her condition rapidly deteriorated. Donor lungs finally became available but were too large for her and had a marginal status for transplantation purposes. Moreover, the donor had a history of treated pulmonary tuberculosis, causing bronchiectasis and fibrosis in the left upper lobe. We decided to perform a lobar lung transplantation in this case, which removes the affected left upper lobe and transplants the right whole lung and the left lower lobe. We also commenced chemoprophylaxis for latent tuberculosis infection with isoniazid immediately after surgery. There was no primary graft dysfunction within the first 72 hours. The patient was extubated on postoperative day 6 and transferred to the general ward on day 26. At 3 months post-transplantation, this patient is alive without infection. Conclusions Our experience suggests that a lobar lung transplantation can be considered not only in cases of size mismatches but also for use of locally damaged lungs. Lungs from a donor who received treatment for pulmonary tuberculosis may be feasible for transplantation with chemoprophylaxis for latent tuberculosis infection. Our current case indicates one possible option for overcoming the persistent shortage of available donor lungs.

본 논문에서는 Parrott (2001)의 감정 모델을 기반으로 사용자 포스팅에 대한 다중 감정 분류 모델(분노, 두려움, 즐거움, 사랑, 슬픔)을 구축하였다. 본 연구는 제 3 자가 타인의 감정을 정의한 이전 연구들과 달리 글을 쓴 저자가 직접 명시한 500,000 개의 감정 정보를 활용하였다는 점에서 차별성을 갖는다. 또한, 문서 단위의 데이터로 모델을 구축해 단어들의 의미론적 관계와 글의 패턴을 기반으로 글 전체가 내포하는 감정을 유추하고 분류하였으며, 포스팅에서 글과 함께 쓰여진 emoji 를 데이터로 활용해 emoji 유무에 따른 모델의 성능을 비교하였다. 그 결과 글의 패턴을 학습하는 LSTM 모델이 57.4%로 가장 높은 성능을 보였으며, 특히 emoji 데이터가 포함될 때 모델의 성능이 58.3%로 향상되었다 (5 가지 감정 분류). 본 연구의 결과는 글 전체가 내포한 감정과 해당 감정을 표현하기 위해 사용된 단어의 감정이 일치하지 않음에도 저자가 표현하려고 했던 감정을 문서 단위에서 유추해냈다는 점에서 의미를 가지며, 이는 복잡한 감정 표현(e.g., 반어법, 은유법)에 대한 감정 분류의 가능성을 제시한다.

Characteristics of Diadochokinesis in Typically Developing Children and Adults

Purpose: The purpose of this study was to examine the characteristics of the rate and perceptual judgment of diadochokinesis (DDK) in typically developing children and adults. Methods: Participants were typically developing children aged 2;6 to 9;11 and normal adults. For DDK tasks, they were asked to repeat [p*a], [t*a], [k*a], [p*at*a], and [p*at*ak*a] accurately and quickly with one breath. The number of repetitions per second was measured as DDK rate for each stimuli. The perceptual judgment of DDK were also performed in terms of regularity, rate, and accuracy using a three-point scale. Results: Children showed increases in the number of repetitions per second for all the DDK tasks with age. However, all the children groups between ages 2;6 and 9:11 exhibited significantly slower DDK rates than adults. In the perceptual judgment of DDK tasks, accuracy, rate, and consistency of sequential motion rates using [p*at*a] and [p*at*ak*a] showed statistically significant differences across age groups. Children demonstrated similar accuracy of SMR tasks with adults after age 6;0. Conclusion: This study showed developmental patterns of speech motor skills based on rate, accuracy, and consistency of DDK tasks. This study provides references for assessing speech motor skills related to children with speech difficulties.

<P>Tri(9-anthryl)borane was successfully applied as an organophotocatalyst for the visible-light-induced trifluoromethylation of unactivated alkenes with CF<SUB>3</SUB>I. The mild reaction conditions tolerated a variety of functional groups, and the reaction could be extended to perfluoroalkylations with C<SUB>3</SUB>F<SUB>7</SUB>I and C<SUB>4</SUB>F<SUB>9</SUB>I. Mechanistic studies revealed that the photoredox catalysis involves an oxidative quenching pathway.</P> [FIG OMISSION]</BR>
