BACKGROUND: 'Masked Hypertension' is a phenomenon of blood pressure that is normotensive by clinic measurement but proves to be hypertensive by 24 hour-AMBP and is associated with many cardiovascular complications and its clinical importance has become the center of public interest. However, in Korea no study concerning masked hypertension has ever been published so far. We investigated the frequency and the related factors of masked hypertension among Koreans. METHODS: Overall, 53 volunteers from Incheon and Seoul, Korea, who were 40 years old and abov were enrolled from August 2003 to August 2004. We checked their blood pressure and pulse rate every hour using an ambulatory blood pressure monitoring device [SpaceLabs 90207] for 24 hours. Masked hypertension was defined as office mean BP less than 140/90 mmHg and daytime mean BP over 135/85 mmHg. RESULTS: Among the total, 15 subjects met the criteria of masked hypertension (28.3%) Current smoking (P=0.021), higher clinic mean SBP (P=0.011) and DBP (P=0.027), and prehypertension (P=0.04) were identified as related factors. And when adjusted for sex by logistic regression, only current smoking was statistically significant (P=0.039) and prehypertension showed borderline significance (P=0.092) (CI=95%). Additionally, mean pulse pressures and mean standard deviation of individual mean SBP were higher in the masked hypertension group. CONCLUSION: The frequency of masked hypertension was 28.3% the and related factors were current smoking and higher office BP, especially prehypertension that was introduced in JNC-7. The fact that the pulse pressure and the variability of individual SBP were higher in the masked hypertension group remains thought-provoking.

OBJECTIVES: To investigate whether smoking and the smoking status are predictors of the incident impaired fasting glucose (IFG) or type 2 diabetes in Korean men. METHODS: A cohort of 1,717 Korean men without IFG or diabetes, who underwent annual periodic health examinations for 4 years (2002-2006), were retrospectively investigated. IFG and diabetes were defined as a serum fasting glucose concentration of 100-125 mg/dL and more than 126 mg/dL, respectively. Cox's proportional hazards model was used to evaluate the association between smoking and development of IFG or type 2 diabetes. RESULTS: A total of 558 cases (32.5%) of incident IFG and 50 cases (2.9%) of diabetes occurred. After controlling for the potential predictors of diabetes, the relative risk for IFG, compared with the never smokers, was 1.02 (95% CI=0.88 to 1.19) for the ever-smokers, 0.96 (95% CI=0.79-1.16) for those who smoked 1-9 cigarettes/d, 1.15 (95% CI=1.01 to 1.30) for those who smoked 10-19 cigarettes/d, and 1.31 (95% CI=1.10 to 1.57) for those who smoked 20 or more cigarettes/d (the P value for the current smokers was only p<0.002). The respective multivariate adjusted relative risks for type 2 diabetes, compared with the neversmokers, were 1.07 (95% CI=0.64 to 1.92), 1.47 (95% CI=0.71 to 3.04), 1.84 (95% CI=0.92-3.04), and 1.87 (95% CI=1.13-3.67), respectively (the P value for the current smokers was only p=0.004). CONCLUSIONS: The smoking status and the number of cigarettes smoked daily are associated with an increased risk for developing IFG or type 2 diabetes in Korean men.

BACKGROUND: Decreased activities of daily living (ADL) in elderly people are related to decreased quality of life and death and are a clinically important issue. However, few studies have investigated the various characteristics and risk factors for a decline in ADL among elderly in-patients in geriatric hospitals in Korea. METHODS: In total, 163 elderly in-patients with dementia in three geriatric hospitals located in Incheon, Gwangju and Yongin, Korea were surveyed prospectively for associated factors of a decline in ADL after 6 months. RESULTS: On average, the subjects were 79.4+/-7.6 years old, and 67.5% were female. Approximately 63% had Alzheimer type dementia, 36.8% only attended primary school, 73.0% were widowed, and 38.7% had been admitted to hospitals for less than 1 year. The Korean version of the Mini Mental State Examination (K-MMSE) score was 14.1+/-6.5, and the clinical dementia rating was 1.9+/-0.9. In total, 8.6% were bed-ridden and 59.5% and 64.6% had never experienced fecal and urinary incontinence, respectively. Total ADL scores declined after 6 months follow-up, and significantly associated factors were low K-MMSE score, fecal incontinence, and co-existence of fecal and urinary incontinence. CONCLUSION: Low K-MMSE scores, fecal incontinence, and the co-existence of fecal and urinary incontinence were associated with ADL declines in elderly in-patients with dementia in long-term care hospitals located in three cities in Korea.

Purpose:
Cysteinyl leukotrienes (CysLTs) have been recognized as key mediators associated with type 2 inflammation in the airways of asthmatic patients. CysLTs are associated with airway constriction, eosinophil recruitment/activation, and airway remodeling. The study aimed to understand the role of CysLTs in adult asthmatics in a real-world clinical setting.
Methods:
One hundred five adult asthmatics who had maintained antiasthmatic medications were enrolled. Asthmatic subjects were classified into 2 groups according to urinary leukotriene E4 (uLTE4) levels, and their clinical parameters and inflammatory mediators, including forced expiratory volume in 1 second (FEV1) %, fractional exhaled nitric oxide (FeNO), blood eosinophil count, serum periostin (sPON), and urinary eosinophil derived neurotoxin (uEDN) were compared between the high-uLTE4 and low-uLTE4 groups.
Results:
The prevalence of chronic rhinosinusitis (CRS), severe asthma, and aspirin-exacerbated respiratory disease (AERD) were significantly higher in the high-uLTE4 group than in the low-uLTE4 group. The high-uLTE4 group had lower FEV1% and maximal midexpiratory flow %, but higher FeNO levels than the low-uLTE4 group. In addition, blood eosinophil count, sPON, and uEDN levels were significantly higher in the high-uLTE4 group than in the low-uLTE4 group. The presence of AERD and levels of FeNO, sPON, and uEDN were significantly associated with higher uLTE4 levels in asthmatics.
Conclusion
CysLTs are associated with type 2 inflammation in the airways of asthmatic patients, contributing to the development of AERD, CRS, and asthma severity. The stratification of clinical phenotypes according to the uLTE4 level could support optimizing anti-inflammatory therapy for better control of asthma.

PURPOSE: The aims of this study were to determine the factors affecting the outcome of patent ductus arteriosus ligation in very low birth weight infants (VLBWI) and demonstrate the safety of PDA ligation in VLBWI performed in the neonatal intensive care unit (NICU). MATERIALS AND METHODS: From October 1994 to July 2006, medical records of 94 VLBWI weighing < 1,500g who underwent PDA ligation in the NICU of Samsung Medical Center were reviewed retrospectively. Factors affecting the final outcome of PDA ligation were evaluated by dividing the infants into 3 groups according to mortality and major morbidities as follows: mortality group (Mo), major morbidity group (Mb), and no major morbidity group (NM). RESULTS: In the Mo group, birth weight was significantly lower and the preoperative mean FiO(2) and mean dopamine dose were significantly higher than those in the other 2 groups. There was no significant difference in gestational age, incidence of RDS, number of courses of indomethacin, surgery-related factors, including weight and age at surgery, perioperative vital signs, and complications after surgery between the 3 groups. During surgery in the NICU, there were no significant hemodynamic instability or serious acute complications. CONCLUSION: The factors affecting the outcome of surgery in VLBWI are not the factors related to surgery but the preoperative conditions related to the underlying prematurity. PDA ligation of VLBWI performed in the NICU is safe without serious complications.

BACKGROUND: We sought to determine the association between serum gamma-glutamyltransferase (GGT) levels within the normal range and the risk for development of impaired fasting glucose (IFG) or type 2 diabetes. METHODS: This retrospective cohort study spanned four years (2002~2006) with 1,717 Korean men who underwent periodic health examinations at a university hospital in Incheon, Korea and were not diagnosed with IFG or type 2 diabetes. Fasting plasma glucose levels were measured at the annual health examination. IFG and diabetes were defined as a serum fasting glucose concentration of 100~125 mg/dL and more than 126 mg/dL, respectively. Cox's proportional hazards model was used to evaluate the association between serum GGT levels and development of IFG or type 2 diabetes. RESULTS: There was a strong dose-response relationship between serum GGT levels and the incidence of IFG and diabetes. A total of 570 cases (33.2%) of incident IFG and 50 cases (2.9%) of diabetes were found. After controlling potential predictors, the relative risks for the incidence of IFG for GGT levels < or = 19, 20~25, 26~34, 35~50 and > or = 51 were 1.00, 0.99, 1.17, 1.23 and 1.38 respectively (P for trend 0.015), and for the incidence of diabetes were 1.00, 1.44, 1.80, 2.55 and 2.58 respectively (P for trend 0.050). CONCLUSION: The risk for development of IFG and type 2 diabetes increased in a dose-dependent manner as serum GGT increased within its normal range in Korean men.

BACKGROUND/AIMS: The treatment for steroid-refractory acute graft versus host disease (GVHD) after allogeneic stem cell transplantation (allo-SCT) needs to be standardized. We report our clinical experience with etanercept for steroid-refractory acute GVHD. METHODS: Eighteen patients who underwent allo-SCT and presented with steroid-refractory acute GVHD at Ajou University Hospital were studied retrospectively. They were given 25 mg of etanercept subcutaneously twice weekly for 4 weeks. The clinical responses were evaluated with regard to the severity of acute GVHD. RESULTS: The median patient age was 43.5 years. Using nonparametric tests, etanercept had a down-grading effect on acute GVHD (p = 0.005), although no patient experienced complete remission. Partial responses were seen in 80%, 17%, and 57% of grade II to IV patients, respectively. Skin and gut GVHD were well controlled with etanercept, whereas hepatic GVHD was not. Four patients died of fatal infections. No factors affecting the clinical outcome of etanercept were identified. CONCLUSIONS: Etanercept has a modest effect on steroid-refractory acute GVHD after allo-SCT, with tolerable side effects.

BACKGROUND: As individuals age, there is an obvious decline in their physical activity level. Thus, this is an area where an easy to use assessment instrument is needed. But presently, there is no tool that meets this need. In addition, there is no such instrument tailored for the Korean elderly. This study aimed to fill this void by developing a physical activity assessment instrument for this particular population that is easy to use. METHODS: Item collection was performed through a literature review and a survey of 100 elderly individuals residing in a community setting. Items were selected through expert consensus; and the Physical Activity Questionnaire for elderly (PAQE) was created. For validation, 120 community dwelling elderly persons were enrolled. PAQE and an accelerometer were administered to each participant, and the questionnaire was re-administered 2 weeks later. The Spearman rho between the questionnaire and the accelerometer was calculated for concurrent validity. The Cronbach's alpha was calculated for internal consistency. Test-retest reliability was assessed by calculating the Spearman rho. RESULTS: Of the 119 participants, 80.34% were female with the average age being 72.74+/-7.29 years. Energy expenditure measured by the accelerometer was 220.36+/-96.96 kcal/day compared to 368.33+/-257.29 kcal/day measured through the developed questionnaire. Although the Spearman rho between the energy expenditure measured by the accelerometer and calculated through the recreational activity report in the questionnaire was 0.235 (p=0.011), the total energy expenditure was 0.105 (p=0.259) and the energy expenditure by household activity was 0.002 (p=0.983). The Cronbach's alpha was 0.781. The Spearman rho was 0.720 (p<0.001) for test-retest reliability. CONCLUSION: Our findings show that PAQE is a reliable questionnaire, a valid instrument for estimating energy expenditure during recreational physical activity in the Korean elderly person. However, energy expenditure of household activity did not correlate well with the accelerometer. In conclusion, the PAQE questionnaire can be used to assess kinds and frequency of household activities.
