BACKGROUND: Inhibitory antibodies to factor VIII (FVIII) or IX (FIX) are important issues when managing patients with hemophilia A or B. Advances in bypassing agents such as recombinant activated FVII (rFVIIa) and activated prothrombin complex concentrates (APCC) have enabled the aggressive management of hemophilia with inhibitors during emergency or elective surgery. This study provides an updated evaluation of the safety and effectiveness of bypassing agents in treating perioperative bleeding. METHODS: We reviewed the records of hemophilia patients with inhibitors who underwent surgery between May 2008 and July 2014 using bypassing agents or high-dose FVIII concentrates at a single center. RESULTS: In total, 36 surgeries (24 orthopedic, 12 other) were conducted in 18 hemophilia patients with inhibitors. The median inhibitor titer at surgery was 14 (range, 0.7-1,900) Bethesda units. Most patients had high-responding inhibitors. In total, 25 patients received APCC, 9 with rFVIIa initially. In most cases, bleeding stopped or was well controlled; however, bleeding in 6 patients was controlled using sequential bypassing therapy. Hemostatic efficacy of bypassing agents in various surgeries, based on the final patient outcome, was 94.4% (34/36). Among 5 emergency surgeries, 2 deaths occurred. CONCLUSION: Good control of hemostasis can be achieved using bypassing agents in hemophilia patients with inhibitors who are undergoing surgery. Thorough planning is needed before elective surgery and more active and aggressive management may be needed for emergency surgery. Use of bypassing agents can facilitate safe and successful surgeries in hemophilia patients with inhibitors.

BACKGROUND: A high level of public awareness of stroke may reduce the stroke risk. The aim of this study was to assess the public's awareness of stroke warning signs and risk factors, and to determine the associated factors. METHODS: The study population was 2492 community-dwelling adults aged 50 years and older who participated in the 2010 baseline Dong-gu Study. Information regarding knowledge of stroke warning signs, stroke risk factors, and demographics was collected using standardized open- and closed-form questionnaires. RESULTS: The stroke warning signs that were most frequently identified by respondents were "sudden numbness or weakness" (73.7%) and "sudden difficulty in speaking or in understanding speech" (73.6%). In multivariate analysis, incomplete awareness of stroke warning signs was significantly associated with a lower education level, no history of past stroke, and incorrect knowledge of the definition of stroke. Hypertension and stress were most commonly recognized as risk factors when open-ended questions were used (by 22.3% and 14.1% of the respondents, respectively) and also with close-ended questions (77.7% and 82.4%, respectively). In multivariate analysis, older age, current smoking, lower education level, and incorrect knowledge of the definition of stroke were associated with a worse awareness of stroke risk factors. CONCLUSIONS: A community-based program is needed to improve public awareness of the warning signs and risk factors for stroke. In order to reduce the risk of stroke, public health education and media efforts should focus on people who are older and have a lower level of education.

PURPOSE: Endocrine-disrupting chemicals interfere with the endocrine system and therefore affect growth and pubertal progression. The study aim was to compare the growth and pubertal progression in wild-type female rats with different bedding types. METHODS: Twenty 5-week-old female wild-type Sprague Dawley rats were randomly assigned to two groups with different bedding types: one group received wood shaving bedding, while a second group received corncob bedding. We determined crown-rump length and body weight as anthropometric measurements and assessed the serum growth hormone (GH) and estradiol levels. The gh1 mRNA expression levels were compared using quantitative real time transcription polymerase chain reaction. The estrous cycle was evaluated by vaginal smear. RESULTS: The anthropometric measurements were not significantly different between the two groups. The mean relative expression of the gh1 gene was lower in the corncob bedding group than that in the wood shaving group (P=0.768). Meanwhile serum GH and estradiol were increased in the wood shaving bedding group; however this difference was not statistically significant. The time to first estrus and the length of the estrous cycle were increased in the corncob bedding group; the proportion of normal estrous cycles was also decreased. These findings indicate irregularities in the estrous cycle. CONCLUSION: Endocrine-disrupting chemicals in corncob bedding might be associated with time to first estrus and length of the estrous cycle. Therefore, the type of bedding should be considered as a factor affecting pubertal progression in rodents.

BACKGROUND: Dipeptidyl peptidase-4 (DPP-4) inhibitor add-on therapy is a new option for patients with inadequately controlled type 2 diabetes who are taking combined metformin and sulfonylurea (SU). We evaluated the efficacy and safety of this triple therapy and the characteristics of rapid responders and hypoglycemia-prone patients. METHODS: We included 807 patients with type 2 diabetes who were prescribed a newly added DPP-4 inhibitor to ongoing metformin and SU in 2009 to 2011. Glycemia and other metabolic parameters at baseline, 12, 24, and 52 weeks, as well as episodes of hypoglycemia were analyzed. Rapid responders were defined as patients with > or =25% reduction in glycosylated hemoglobin (HbA1c) within 12 weeks. RESULTS: At baseline, while on the submaximal metformin and SU combination, the mean HbA1c level was 8.4%. Twelve weeks after initiation of DPP-4 inhibitor add-on, 269 patients (34.4%) achieved an HbA1c level < or =7%. Sixty-six patients (8.2%, 47 men) were rapid responders. The duration of diabetes was shorter in rapid responders, and their baseline fasting plasma glucose (FPG), HbA1c, C-peptide, and homeostasis model assessment of insulin resistance were significantly higher. Patients who experienced hypoglycemia after taking DPP-4 inhibitor add-on were more likely to be female, to have a lower body weight and lower triglyceride and FPG levels, and to have higher homeostasis model assessment of beta-cells. CONCLUSION: An oral hypoglycemic triple agent combination including a DPP-4 inhibitor was effective in patients with uncontrolled diabetes. Proactive dose reduction of SU should be considered when a DPP-4 inhibitor is added for rapid responders and hypoglycemia-prone patients.

PURPOSE: The purpose of this study was to analyze the status of inpatient care for acute first-ever stroke at three general hospitals in Korea to provide basic data and useful information on the development of comprehensive and systematic rehabilitation care for stroke patients. MATERIALS AND METHODS: This study conducted a retrospective complete enumeration survey of all acute first-ever stroke patients admitted to three distinct general hospitals for 2 years by reviewing medical records. Both ischemic and hemorrhagic strokes were included. Survey items included demographic data, risk factors, stroke type, state of rehabilitation treatment, discharge destination, and functional status at discharge. RESULTS: A total of 2159 patients were reviewed. The mean age was 61.5+/-14.4 years and the ratio of males to females was 1.23:1. Proportion of ischemic stroke comprised 54.9% and hemorrhagic stroke 45.1%. Early hospital mortality rate was 8.1%. Among these patients, 27.9% received rehabilitation consultation and 22.9% underwent inpatient rehabilitation treatment. The mean period from admission to rehabilitation consultation was 14.5 days. Only 12.9% of patients were transferred to a rehabilitation department and the mean period from onset to transfer was 23.4 days. Improvements in functional status were observed in the patients who had received inpatient rehabilitation treatment after acute stroke management. CONCLUSION: Our analysis revealed that a relatively small portion of patients who suffered from an acute first-ever stroke received rehabilitation consultation and inpatient rehabilitation treatment. Thus, applying standardized clinical practice guidelines for post-acute rehabilitation care is needed to provide more effective and efficient rehabilitation services to patients with stroke.

BACKGROUND: We aim to discuss the overall effect of customer service manual (CSM) on service industry workers using Korean Working Condition Survey. METHODS: Out of 50,007 total survey participants, 11,946 customer service workers were included in the current study (5613 men, 6333 women). Answers to survey questions were used to define the use of CSM, emotional burden, emotional dissonance, engaging angry customers and other covariates. Emotional burden included either depressive event or stress level. Odds ratio (OR) with 95% confidence interval (95% CI) of experiencing emotional burden was calculated by logistic regression model. Interaction effect between CSM and engaging angry customer on emotional burden was also estimated. RESULTS: Out of 11,946 subjects, total of 3279 (27.4%) have experienced emotional burden. OR (95% CI) of experiencing emotional burden was 1.40 (1.19–1.64) in men and 1.25 (1.09–1.44) in women. There was gender difference in interaction effect between the use of CSM and engaging angry customers. In men, OR (95% CI) was 3.16 (1.38–7.23) with additive effect when always engaging angry customers with CSM compared to rarely engaging without CSM, while in women OR (95% CI) was 8.85 (3.96–19.75) with synergistic effect. Moreover, the risk of depressive event increased only in women with OR (95% CI) 2.22 (1.42–3.48). CONCLUSIONS: Our current study highlighted association between emotional burden and CSM in both men and women service workers. Furthermore, women were affected more severely by CSM. The results from current study suggest that CSM should be changed appropriately to benefit workers.

BACKGROUND: The aim of this study was to investigate sarcopenia and its association with cardiometabolic risk factors in a community-based elderly cohort in Korea. METHODS: We recruited 287 men and 278 women aged 65 years or older and without physical disability. Appendicular skeletal muscle mass (ASM) was measured with dual energy X-ray absorptiometry. We used two definitions for sarcopenia-ASM divided by height2 (kg/m2) or by weight (%) <1 SD below the sex-specific mean for young adults. We compared RBP-4, adiponectin, hsCRP, lipid profiles, and insulin resistance between the sarcopenic and normal groups using ASM/Ht2 and ASM/Wt. RESULTS: The prevalence of sarcopenia was 35.3% in men and 13.4% in women with sarcopenia defined by ASM/Ht2. However, it was 38.3% in men and 62.6% in women by ASM/Wt. In correlation analysis, body mass index was positively correlated with ASM/Ht2 and negatively correlated with ASM/Wt. The sarcopenic group, when defined as ASM/Ht2, showed lower RBP4, fasting plasma glucose, and HOMA-IR and higher adiponectin than the normal group but not significantly different lipid profiles. The sarcopenic group defined by ASM/Wt had higher RBP4, fasting plasma glucose, and HOMA-IR, and lower adiponectin than the normal group in both sexes. Only in the males did the sarcopenic group defined by ASM/Wt reveal higher total cholesterol, triglycerides, and LDL cholesterol, and lower HDL cholesterol than the normal group. CONCLUSION: In conclusion, the sarcopenic group defined by ASM/Wt was more closely associated with cardiometabolic risk factors than the normal group in a community-based elderly cohort.

We evaluated the malignancy and nondiagnostic rates using fine needle aspiration cytology (FNAC) results in thyroid nodules smaller than 1 cm according to the subdivided size. We retrospectively reviewed the medical records of all subjects underwent FNAC from 2003 to 2009 in our hospital, and 2,756 patients of subcentimeter thyroid nodules with one or more suspicious sonographic features and 7,105 with nodule sized 1 cm or more were included. The malignancy rate was higher in those subcentimeter nodules with suspicious sonographic findings than the nodule sized 1cm or more (19.7% vs 7.8%, P < 0.001). We grouped the nodules based on size with mm interval and observed that the malignancy rate did not decrease but the nondiagnostic results increased its size decrement. When we divided the subjects arbitrarily into a 5 mm or smaller and a 6-9 mm sized group, nondiagnostic cytology findings were reported more frequently in the smaller group (24.3% vs 18.1%, P = 0.001), while the rate of "malignant" was similar (18.3% vs 15.5%, P = 0.123) and the rate of "suspicious for malignancy" was higher (6.8% vs 2.9%, P < 0.001). Therefore when we decide to perform FNAC or not in subcentimeter-sized nodules, we should consider sonographic findings and other clinical risk factors but not the nodular size itself.

PURPOSE: Allergic diseases are triggered by Th2-mediated immune reactions to allergens and orchestrated by various immunological factors, including immune cells and cytokines. Although many reports have suggested that childhood is the critical period in the onset of allergic diseases and aging leads to alter the susceptibility of an individual to allergic diseases, age-related changes in various immunological factors in healthy individuals as well as their difference between healthy and allergic children have not yet been established. METHODS: We investigated the ratio of Th1/Th2 cells and the levels of 22 allergy-related cytokines across all age groups in individuals who were classified as clinically non-atopic and healthy. We also examined their differences between healthy and allergic children to evaluate immunological changes induced by the development of allergic diseases during childhood. RESULTS: The Th1/Th2 ratio rose gradually during the growth period including childhood, reaching peak values in the twenties-thirties age group. Th1/Th2 ratios were significantly lower in allergic children than in healthy controls, whereas 14 of 22 cytokines were significantly higher in allergic children than in healthy controls. On the other hand, there were no differences in Th1/Th2 ratios and cytokines between healthy and allergic adolescents. CONCLUSIONS: In this study, age-related changes in Th1/Th2 ratios were found in normal controls across all age groups, and decreases in Th1/Th2 ratio were observed with increasing of 14 cytokines in allergic children. The results of this study may be helpful as reference values for both monitoring immunological changes according to aging in healthy individuals and distinguishing between normal and allergic subjects in terms of immune cells and soluble factors.
