Background: This study compared the treatment outcomes of patients with multidrug-resistant tuberculosis (MDR-TB) before and after the implementation of public-private mix (PPM). Factors affecting treatment success were also investigated. Methods: Data from culture-confirmed pulmonary MDR-TB patients who commenced MDR-TB treatment at Pusan National University Hospital between January 2003 and December 2017 were retrospectively reviewed. Patients were divided into two groups in terms of PPM status: pre-PPM period, patients who commenced MDR-TB treatment between 2003 and 2010; and post-PPM period, patients treated between 2011 and 2017. Results: A total of 176 patients were included (64 and 112 in the pre- and post-PPM periods, respectively). 36.9% of the patients were resistant to a fluoroquinolone or a second-line injectable drug, or both. The overall treatment success rate was 72.7%. The success rate of post-PPM patients was higher than that of pre-PPM patients (79.5% vs. 60.9%, p=0.008). Also, loss to follow-up was lower in the post-PPM period (5.4% vs. 15.6%, p=0.023). In multivariate regression analysis, age ≥65 years, body mass index ≤18.5 kg/m², previous TB treatment, bilateral lung involvement, and extensively drug-resistant (XDR)- or pre-XDR-TB were associated with poorer treatment outcomes. However, the use of bedaquiline or delamanid for ≥1 month increased the treatment success. Conclusion: The treatment success rate in MDR-TB patients was higher in the post-PPM period than in the pre-PPM period, particularly because of the low rate of loss to follow-up. To ensure comprehensive patient-centered PPM in South Korea, investment and other support must be adequate.

Patients with neurofibromatosis 1 (NF1) are predisposed to develop central nervous system tumors, due to the loss of neurofibromin, an inactivator of proto-oncogene Ras. However, to our knowledge, only three cases of ependymomas with NF1 have been reported in the literature. The authors present a case of NF1 patient with a spinal cord ependymoma. She was referred for about half a year history of increasing numbness that progressed from her fingers to her entire body above the bellybutton. Magnetic resonance imaging revealed a relative-demarcated, heterogeneously enhanced mass lesion accompanied by perifocal edema in C5-7 level, a left-sided T11 spinous process heterogeneously enhanced mass in soft tissue, intervertebral disk hernia in L2-5 level, and widespread punctum enhancing lesion in her scalp and in T11-L5 level. The patient underwent C5-7 laminectomies and total excision of the tumor under operative microscope, and intraoperative ultrasonography and physiological monitoring were used during the surgery. Histopathologically, her tumor was found to be a ependymoma without malignant features (grade II in the World Health Organization classification). Therefore, no adjuvant therapy was applied. Following the operation, the patient showed an uneventful clinical recovery with no evidence of tumor recurrence after one year of follow-up.

Objectives The clinical trial was designed to investigate the safety and effects of Bofu-tsusho-san extracts on the change of the weight, body compositions, serum in obese patients. Methods This study was a 4-weeks, double blind, comparative clinical trial. Eligible subjects had a body mass index(BMI) greater than $25\;kg/m^2$ and waist circumference(WC) longer than 85 cm in woman or 90 cm in man. Among 38 subjects, 36 subjects were randomized either to Bofu-tsusho-san or placebo. After 4 weeks of treatment, we measured anthropometric factors(weight, height, WC, BMI etc.), abdominal fat area by CT scanning, serum lipid(total cholesterol(TC), triglyceride(TG), HDL cholesterol, LDL cholesterol), blood level of variety(glucose, adiponectine, leptin, C-reactive protein(CRP) etc.), blood pressure(BP). Adverse events also evaluated. Results BMI, BP, TG, CRP were reduced and weight, WC, score of KOQOL(Korean version of obesity-related QOL scale), SRI(Stress response inventory) were significant changed in Bofu-tsusho-san. But there were no considerable difference between Bofu-tsusho-san and placebo. there were no serious adverse events in either group. Conclusion There were limitations in this study that it conducted within a short period of 4 weeks. but its weight and WC loss effect was significant and it had few adverse events.

The paramyxean parasite Marteilioides chungmuensis infects the cytoplasm of the eggs of Pacific oysters Crassostrea gigas , resulting in spawning failure of the infected females. Such infected eggs appear as bump-like nodules on the body in late fall when most of the uninfected females complete spawning. In this study, we estimated the quantity of the infected eggs using an enzyme-linked immunosorbent assay (ELISA), which is destroyed by M. chungmuensis parasitism. In December, the infected oysters collected from Tongyoung on the south coast exhibited numerous yellowish bump-like nodules as signs of infection. In histology, the infected oysters exhibited mature eggs in the follicle, which were heavily infiltrated by hemocytes. ELISA indicated that the infected egg mass accounted for 7.52±5.50 percent of the body weight, suggesting the ovarian parasite causes substantial reproductive loss. Histology also indicated that the infected oysters are in a poor nutritional condition, as the digestive gland atrophy (DGA) level is comparatively higher than the uninfected oyster. The total carbohydrate contents in the infected oysters (108.68±44.41 mg/g dry wt) were significantly lower than in uninfected oysters (269.76±50.97 mg/g dry wt), suggesting that M. chungmuensis parasitism also affected the energy storage capacity of the host during the resting stage.

BACKGROUND/OBJECTIVES: There are concerns about the adverse health effects of behavioral changes linked to coronavirus disease 2019 (COVID-19). We conducted a survey to investigate changes in lifestyle habits, including exercise and eating, during the COVID-19 pandemic and their association with changes in weight. SUBJECTS/METHODS: We conducted a survey of 5,000 people in Hakui City, Japan, to assess their lifestyles and diets during the COVID-19 pandemic. A total of 3,992 complete responses were received. We also obtained pre- and post-pandemic health check-up data for 704 of the respondents. These health data were combined with the results of the questionnaire survey to identify factors associated with weight changes. Data were analyzed for 704 individuals. RESULTS: The mean body mass index was 22.5 ± 3.1 kg/m² for respondents whose weight did not change and 25.1 ± 2.7 kg/m² for respondents whose weight increased. The pre-pandemic mean values for abdominal circumference in females and for gamma-glutamyl transferase in males tended to be higher in those whose weight increased. Those with decreased weight tended to be older. Respondents who were already overweight were more likely to gain weight because of COVID-19-related changes in their lifestyle. In males, alcohol consumption was directly associated with weight, and in females, abdominal circumference was more important. CONCLUSION: The study found pre-pandemic overweight individuals likely gained more weight during it, with alcohol consumption being a significant factor for males. Weight loss was more crucial for those over 70, rather than weight gain.

Objectives : To investigate aggravating and mitigating factors of atopic dermatitis and to utilize the outcome in treatment planning. Methods : The research has a cross-sectional study design. Patients' SCORing Atopic Dermatitis (SCORAD) Index, demographic, physical characteristics, social history, serologic index and skin related instrumental measurements were analyzed with correlation and regression analysis method. Results : 48 patients in total were enrolled in the study. Skin Surface Hydration (SSH) and sex were found to be statistically significant aggravating and mitigating factors. As SSH increased, Total SCORAD (tSCORAD) and Objective SCORAD (oSCORAD) increased as well. As SSH decreased, tSCORAD and oSCORAD decreased as well. Female patient had a higher probability of suffering from severer subjective symptoms than that of male. Age, body mass index (BMI), alcohol consumption and smoking, transepidermal water loss (TEWL), IgE, IL-4, IL-5, IL-6, IFN-γ were found not to be statistically significant. There was no correlation between Subjective SCORAD (sSCORAD) and oSCORAD neither with Eczema Area and Severity Index (EASI). Conclusions : Increasing cutaneous moisture should be included in the treatment plan of atopic dermatitis. More emphasis should be put on alleviating subjective discomforts of female patients than that of male. Establishing separate strategies of managing objective eczema status and subjective discomforts respectively should be considered.

Prolific females require better nutrition and feeding practice because of larger litter size and the substantial decline in body fat. Life-time pig output will be compromised if body protein and fat are not properly managed. First litter females are especially vulnerable because they can loose ${\geq}15%$ of whole-body protein. Conservation of body protein mass during first lactation minimizes wean to estrus interval and increases second litter size (up to 1.2 pigs). The ability to influence litter-size by amino acid nutrition is a new dimension in our understanding. A P2 fat depth below 12 mm at farrow and below 10 mm at wean compromised wean to estrus interval (>2 d) and next litter size (0.5 to 1.5 pigs) in sows. It is now clear that a 'modest' excess of feed during the first 72 h of pregnancy decreases embryo viability so that the potential for an increased litter size at birth is not realized. The capacity for milk production by prolific young sows is 25% higher than the standard used previously (NRC, 1988). First litter females averaged 9.82 kg milk/d for a 21 d lactation. Second and third litter counterparts averaged 10.35 kg/d. Milk production was 95% of peak by 10 d of lactation and sows were in greatest negative energy and lysine balance during the first 6 d. Nearly 45% of the total loss in body protein occurred within the first 6 d, but this could reduced to 30-35% by using a more aggressive feeding strategy after parturition. There appear to be 2 phases in lactation for lysine need (d 2-12 vs 12-21). Feeding to the higher level alleviates the second litter size decline. The lysine requirement for lactation can be predicted with accuracy, but we are not able to predict the second limiting amino acid. Mammary uptake of valine relative to lysine and recent work with practical diets suggest that the recent NRC (1998) pattern is realistic and that threonine and valine could be co-limiting for corn-soy diets for prolific sows nursing 10-11 pigs. Empirical studies are needed to refine the ideal pattern so that synthetic lysine can be used with more confidence. Milk fat output for the elite sow is extraordinary and poses an unnecessarily high energetic cost. Methods that reduce mammary fat synthesis will benefit the sow and may enhance piglet growth.

근접촉쌍성 XZ CMi의 BV 측광관측을 수행하여 새로운 광도곡선과 총 7개의 극심시각을 획득하였다. 관측한 극심시각과 지금까지 발표된 극심시각을 수집하여 XZ CMi의 궤도 공전주기를 분석한 결과, 이 쌍성계의 공전주기가 지난 70년간 영년 주기감소와 더불어 규칙적으로 변화함을 확인하였다. 규칙적인 변화를 제3천체에 의한 광시간 효과로 가정하여 0.0056일의 진폭, 약 29년의 주기, 그리고 0.71의 궤도이심율의 광시간 궤도를 결정하였다. 관측된 영년 주기감소($-5.26{\times}10^{-11}d/P$)를 자기제동 항성풍의 각운동량 손실에 의한 주기감소($-8.20{\times}10^{-11}d/P$)와 질량이 작은 반성에서 주성으로 질량 이동에 의한 주기 증가($2.94{\times}10^{-11}d/P$)가 동시에 일어나는 것으로 해석하였다. 이런 관점에서 AML에 의한 주기감소율은 질량 이동에 의한 공전주기 증가율보다 그 크기가 약 3배 정도 크며, 반성에서 년간 $3.21{\times}10^{-8}M_{\odot}$의 질량이 주성으로 이동된다. 관측된 BV 광도곡선을 최근의 Wilson & Devinney 쌍성코드로 주성의 온도를 달리하는 두가지 모형(8200K와 7000K)을 상정하여 분석하였다. 두가지 모형 해 모두 XZ CMi가 반성이 로쉬 로브를 채웠으나, 주성은 아직 로쉬 로브를 채우지 않은 근접촉 쌍성임과 약 15-17%의 제3광도가 이 계에 있음을 보여준다. 그러나, 제3광도를 내는 천체가 주기연구에서 제안한 제3천체와 동일 천체가 아닌 것은 확실하다. 두 모형의 $\sum(O-C)^2$의 차이는 너무 미미하여, 현 시점에서 어느 해가 더 관측치를 잘 맞추는 지를 가릴 수는 없었다. 그간 연구자간에 불일치하였던 질량비의 다양성 문제는 아직도 풀리지 않는 숙제로 남아있다. 이를 해결하기 위해서 분광시선속도곡선과 스펙트럼의 관측과 더불어 정밀 측광관측이 필요하다.
