<P>Lactoferrin (LF) and retinoic acid (RA) are enriched in colostrum, milk, and mucosal tissues. We recently showed that LF-induced IgA class switching through binding to betaglycan (transforming growth factor-beta receptor III, T beta RIII) and activation of canonical TGF-beta signaling. We investigated the combined effect of LF and RA on the overall IgA response. An increase in IgA production by LF was further augmented by RA. This combination effect was also evident in Ig germ-line alpha (GL alpha) transcription and GLa promoter activity, indicating that LF in cooperation with RA increased IgA isotype switching. We subsequently found that RA enhanced T beta RIII expression and that this increase contributed to LF-stimulated IgA production. In addition to the IgA response, LF and RA in combination also enhanced the expression of the gut-homing molecules C-C chemokine receptor 9 (CCR9) and alpha 4 beta 7 on B cells. Finally, peroral administration of LF and RA enhanced the frequency of CCR9(+)IgA(+) plasma cells in the lamina propria. Taken together, these results suggest that LF in cooperation with RA can contribute to the establishment of gut IgA responses.</P>

Purpose: Many university students are under a lot of job-seeking stress because the employment rate is low. This study sought to determine the relationship between job-seeking stress, self esteem, self efficacy and appearance management behavior amongst university students focusing on nursing. Methods: This descriptive correlational study evaluated the relationships between job-seeking stress, self esteem, self efficacy and appearance management behavior of 340 university students was conducted between September 1 and October 5, 2015. Results: The correlational analysis between job-seeking stress, self esteem, self efficacy and appearance management behavior revealed a negative correlation between job-seeking stress, self esteem and self efficacy and a positive correlation between job-seeking stress and appearance management behavior. In addition, age also correlated with self esteem, self efficacy and appearance management behavior. Conclusion: Stress correlated with self esteem and self efficacy and appearance management behavior. Therefore job-seeking stress may be reduced through not only self esteem and self efficacy enhancement programs but also management according to age.

( Bo Ra Yoon ),( Chang Hwan Seol ),( In Kyung Min ),( Min Su Park ),( Ah Young Leem ),( Moo Suk Park ),( Young Sam Kim ),( Kyung Soo Chung ) 대한결핵 및 호흡기학회 2018 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.126 No.0

Background: In critically ill patients, previous scoring methods are mainly aimed at predicting the mortality of sepsis patients, but early detection of sepsis is also important in patients with suspected infection. In the revised sepsis definition, the concept of qSOFA was introduced to diagnose sepsis more simply. However qSOFA has no concept of suspected infection, and it is divided into two stages for non-ICU and ICU patients to diagnose sepsis. In this study, we have developed a Sepsis Predictive Score (SPS) to help predict sepsis in a quick and simple way. Method: We retrospectively reviewed the records of ICU patients at Yonsei University College of Medicine from March 2015 to September 2017. The primary outcome was to discriminate sepsis in patients at the time of medical ICU admission. Patients were divided into 8:2 and assigned to a train set and a validation set. We use Logistic regression, Hosmer-Lemeshow’s test and Cross-validation to derive the SPS and validate the model. Results: The 989 patients were enrolled in this study; Sepsis was 77.4 % (n=765). The SPS was developed by analyzing the variables and then assigning weights to the selected variables, mean arterial pressure, shock index, lactate and procalcitonin. As the total points of SPS increased, the sepsis probability increased. The area under the curve (AUC) was 0.754, 0.615, 0.763 and 0.668 for SPS, qSOFA, SOFA and APACHE II, and SPS was statistically non-inferior to SOFA. Conclusions: SPS is a simple score that can detect sepsis more rapidly in critically ill patients.
