  • This study was conducted to investigate the taxonomic composition and diversity of fecal microbiota between birth and weaning stages of Halla horses using 16S rRNA gene amplicon sequencing analysis. Proteobacteria (35.7%) and Firmicutes (45.6%) were identified as the most common phylum in birth and weaning, respectively. Escherichia (19.7%) and Clostridium (14.0%) were observed as the most dominant genus in birth, and Fibrobacter (6.6%) was the highest in weaning. The results of α-diversity showed that the richness and evenness in microbial communities were statistically significant (p<0.001) in birth and weaning. The results of β-diversity indicated that the birth and weaning stages were clearly divided into two groups at the genus and species levels. Permutational multivariate analysis of variance (PERMANOVA) showed that the microbiota composition differences between birth and weaning were statistically significant (q<0.001). A linear discriminant analysis effect (LEfSe) was performed to select taxonomic makers between the birth and weaning stages. On the genus level, Escherichia, Bacteroides, Clostridium, and Methylobacterium were relatively abundant at birth, whereas Fibrobacter was more abundant at weaning. We expect that this research can be utilized as basic data in the identification of microbial communities involved in disease prevention and nutrient absorption in Halla horses.

  • BACKGROUND/OBJECTIVES: This study aimed to investigate cancer-specific survival (CSS) and associated risk factors in elderly gastric cancer (EGC) patients. SUBJECTS/METHODS: EGC patients (≥ 70 yrs) who underwent curative gastrectomy between January 2013 and December 2017 at our hospital were included. Clinicopathologic characteristics and survival data were collected. Receiver operating characteristic (ROC) analysis was used to extract the best cutoff point for body mass index (BMI). A Cox proportional hazards model was used to determine the risk factors for CSS. RESULTS: In total, 290 EGC patients were included, with a median age of 74.7 yrs. The median follow-up time was 31 (1-77) mon. The postoperative 1-yr, 3-yr and 5-yr CSS rates were 93.7%, 75.9% and 65.1%, respectively. Univariate analysis revealed risk factors for CSS, including age (hazard ratio [HR] = 1.08; 95% confidence interval [CI], 1.01-1.15), intensive care unit (ICU) admission (HR = 1.73; 95% CI, 1.08-2.79), nutritional risk screening (NRS 2002) score ≥ 5 (HR = 2.33; 95% CI, 1.49-3.75), and preoperative prognostic nutrition index score < 45 (HR = 2.06; 95% CI, 1.27-3.33). The ROC curve showed that the best BMI cutoff value was 20.6 kg/m2. Multivariate analysis indicated that a BMI ≤ 20.6 kg/m2 (HR = 2.30; 95% CI, 1.36-3.87), ICU admission (HR = 1.97; 95% CI, 1.17-3.30) and TNM stage (stage II: HR = 5.56; 95% CI, 1.59-19.43; stage III: HR = 16.20; 95% CI, 4.99-52.59) were significantly associated with CSS. CONCLUSIONS: Low BMI (≤ 20.6 kg/m2), ICU admission and advanced pathological TNM stages (II and III) are independent risk factors for CSS in EGC patients after curative gastrectomy. Nutrition support, better perioperative management and early diagnosis would be helpful for better survival.

  • Typological theories of offending postulate that childhood-onset delinquents have a high likelihood of being serious and chronic offenders and that there are a distinct set of risk factors predicting early-onset antisocial behaviors. It is useful to empirically classify children into subgroups based on their deviant behaviors because it helps us to identify unique factors associated with each subgroup. Using the first two waves of the Korean Youth Panel Survey, Elementary School Data, this study aimed(a) to empirically classify 5th graders into latent delinquent subgroups, and (b) to examine the impact of individual, familiar, school, and peer factors on the latent delinquent classes. Latent class analysis yielded three latent classes based on 15 indicators of deviant behaviors - delinquent class, low-level delinquent class, & normative class. The results from multivariate multinomial logistic regression analyses revealed that being male, reporting low self-control, coming from poor family, high association with deviant peers, and being bullied increased the risk of being in the delinquent class. Moreover, low self-control, aggression, domestic violence, low level of attachment to teachers, and deviant peers independently increased the risk of being in the low-level delinquent class compared to the normative class. Based on the study findings, implications for practice as well as future studies were discussed.

  • Objectives : This study was aimed to clarify the relationship between the dampness-phlegm diagnosis and internal carotid artery stenosis by measuring carotid artery sonography in cerebral infarction patients. Methods : One hundred eighty subjects were recruited from the patients admitted to the Department of Internal Medicine at Kyunghee university oriental medical center from September 2008 to July 2010. We assessed one hundred eighty patients' carotid artery sonography data and diagnosed dampness-phlegm by oriental medical diagnosis. then, analyzed their characteristics, risk factor, lifestyle, metabolic syndrome, body mass index, Waist/Hip ratio(W/H ratio) and dampness-phlegm diagnosis. Results : On the demographic variables of the patients, age, smoking, W/H ratio and dampness-phlegm group were significantly higher in severe internal carotid artery(ICA) stenosis group than in the control group. According to the significant difference in dampness-phlegm group, we analyzed dampness-phlegm related index for pattern identifications by ICA stenosis. As a result, sputum, bowel sound, chest discomfort, slippery pulse were significantly higher in the severe ICA stenosis group than in the control group. In multivariate analysis, dampness-phlegm group showed close relationship with severe ICA stenosis group. Conclusion : According to the analysis, significance between dampness-phlegm diagnosed patients group and severe ICA stenosis were clarified. These results can be utilized in the future as a basis material.

  • Objectives: The coronavirus disease 2019 (COVID-19) pandemic has increased the workload of healthcare workers (HCWs), impacting their health. This study aimed to assess sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and identify factors associated with poor sleep among HCWs in Vietnam during the COVID-19 pandemic. Methods: In this cross-sectional study, 1000 frontline HCWs were recruited from various healthcare facilities in Vietnam between October 2021 and November 2021. Data were collected using a 3-part self-administered questionnaire, which covered demographics, sleep quality, and factors related to poor sleep. Poor sleep quality was defined as a total PSQI score of 5 or higher. Results: Participants' mean age was 33.20±6.81 years (range, 20.0-61.0), and 63.0% were women. The median work experience was 8.54±6.30 years. Approximately 6.3% had chronic comorbidities, such as hypertension and diabetes mellitus. About 59.5% were directly responsible for patient care and treatment, while 7.1% worked in tracing and sampling. A total of 73.8% reported poor sleep quality. Multivariate logistic regression revealed significant associations between poor sleep quality and the presence of chronic comorbidities (odds ratio [OR], 2.34; 95% confidence interval [CI], 1.17 to 5.24), being a frontline HCW directly involved in patient care and treatment (OR, 1.59; 95% CI, 1.16 to 2.16), increased working hours (OR, 1.84; 95% CI,1.37 to 2.48), and a higher frequency of encountering critically ill and dying patients (OR, 1.42; 95% CI, 1.03 to 1.95). Conclusions: The high prevalence of poor sleep among HCWs in Vietnam during the COVID-19 pandemic was similar to that in other countries. Working conditions should be adjusted to improve sleep quality among this population.

  • Purpose: Sepsis is the most common cause of neonatal death accounting for 30-50% of mortality annually in developing countries. This study was to determine the prognostic factors of neonatal sepsis mortality. Methods: A retrospective cohort was conducted in Dr. R. Sosodoro Djatikoesoemo Governor Hospital from April 2021 to September 2021 on 121 neonates in the neonatal intensive care unit (NICU) diagnosed with sepsis. The inclusion criteria were neonates aged 0-28 days, admitted to the NICU, and diagnosed with sepsis. The exclusion criteria were incomplete data and the presence of congenital abnormalities. A χ2 test was performed on the sex, gestational age, mode of delivery, birth weight, APGAR score, birthplace, and blood culture. A normality test was performed on leukocytes, lymphocytes, neutrophils, platelets, C-reactive protein (CRP), and length of stay. Then performed a Mann-Whitney test. Results: Birth weight (P=0.038), gestational age (P=0.009), and blood culture (P=0.014) showed a significant relationship with the neonatal sepsis outcome while Mann-Whitney test showed significant differences in the platelets (P=0.018), CRP (P=0.002), and length of stay (P<0.001). Multivariate analysis showed that 3 prognostic factors associated with neonatal sepsis mortality were prematurity (odds ratio [OR], 3.906; 95% confidence interval [CI], 1.344-11.356; P=0.012), low birth weight (LBW, OR, 2.833; 95% CI, 1.030-7.790; P=0.044), and gram-negative bacteria (OR, 4.821; 95% CI, 1.018-22.842; P=0.047). Conclusions: Prematurity, LBW, and gram-negative bacteria were associated with the prognostic factors of neonatal sepsis.

  • This study was a secondary data analysis using statistics from the 13th (2017) Korea Youth Risk Behavior Web-based Survey (KYRBS) to investigate the relationship between health behaviors and physical activity among Korean adolescents. A total of 62,276 adolescents in middle and high schools enrolled in this study. Physical activity utilized moderate and vigorous physical activity variables. Health behaviors used smoking, drinking, eating, sedentary behavior, and sleep duration variables. Statistical analyses were performed applying complex sample analysis method. Chi-square tests were used to compare physical activity according to health behaviors. Multivariate multinomial logistic regression analyses were conducted to examine the relationship between health behaviors and physical activity, adjusted for general characteristics. Current smoking and current drinking were associated with high levels of moderate and vigorous physical activity. Consuming fruits≥1 times/day, vegetables≥3 times/day, and sweet drinks≥3 times/week were associated with high levels of moderate and vigorous physical activity. Eating breakfast≥5 times/week was associated with high levels of moderate physical activity, but not with vigorous physical activity. Sedentary behavior≥2 hour/day was associated with low levels of moderate and vigorous physical activity. Sleep duration<7 hour/day was associated with high levels of moderate physical activity and low levels of vigorous physical activity. These findings suggest that since there is an interrelationship between health behaviors and physical activity among adolescents, intervention programs aiming at promoting physical activity and healthy lifestyles should consider a multiple behavior approach rather than an individual behavior approach.

  • This study is a nonequivalent control group pretest-posttest study to determine the effects of a make up program on the self-esteem and anxiety of the elderly female dementia patients. This research was done between April 13th and May 1st, 2009. The subjects were 41 dementia patients in an elderly hospital in Honam Area. Twenty dementia patients in the experimental group got the make up measures during the two week experimental period and twenty one dementia patients in the contrast group didn't get any measure during the two week period. Make up measures were given to the experimental group 10 times for the two week period. This study used the self-esteemscale which was developed by Rosenberg(1965) and was translated and modified by Jeon Pyung Je(1974) into Korean. The anxiety status scale which this study used was developed by Spielberger(1970) and was translated and modified by Kim Jeong Taek(1991) into Korean. Collected data were analyzed with SPSS Win 12.0. T-test and multivariate analysis were done to test the hypothesis. This study also used a method of observation. The results of this study are following. After the two week make up measures, the experimental group had more self esteem and less anxiety status than the contrast group. The differences were statistically significant. The result of the observation also supported the research hypothesis. Based on this result, we suggest the make up program as an appropriate and useful nursing care intervention program for female dementia patients.

  • The purposes of this study were to compare the disability prevalence and its related factors between men and women. The data used for the analysis was the National Health and Nutrition Survey, 2005, and the instrument of measuring disability was the K-ADL which had been developed by Won(2002). Chi-square test and multivariate logistic regression were used to test the gender difference. In the bivariate analyses, women had more disabilities than men among the entire elderly and the young elderly. However, there was not gender difference of disability among the old elderly. After controlling for age and other factors related to disability, no gender differences in the prevalence of disability were found. However, in the same analyses for the individual activities of daily living, men had more disabilities than women for all the activities except bathing and incontinence control. In conclusion, women's higher prevalence of disability in the univariate and bivariate analyses were spurious, because it was disappeared when other related factors to disability were controled for and women's disability became lower than men for some activities of daily living.

  • Purpose The purpose of this study was to examine the relationship between physical activities, sleep disturbance, and health related quality of life (HRQOL) in patients with chronic obstructive pulmonary disease (COPD). Methods A descriptive survey design used pretest dataset of COPD symptom management intervention study (N=245). Measures included the international physical activity questionnaire, the COPD and asthma sleep impact scale, and the St. George's respiratory questionnaire of HRQOL. The data were analyzed using descriptive analysis, t-test, ANOVA, Pearson correlation coefficients, and simultaneous multiple regression by the SPSS WIN 18.0 program. Results The mean scores (SD) of HRQOL and sleep disturbance were 36.04 (19.43) and 14.33 (6.20), respectively. About 32% of participants were physically inactive. The multivariate approach showed the patients who have more sleep disturbance (β=.27), lower levels of FEV1 % predicted (β=-.23), lower physical activities (β=-.19), lower household income (β=-.16), and diagnosed longer than 5 years (β=.14) reported lower HRQOL (R2=.34). Conclusion The findings of this study suggest that improving the quality of sleep and physical activities can be efficient strategies for HRQOL in patients with COPD. Future research in enhancing HRQOL through improving sleep quality and physical activities is needed.
