PURPOSE: The aim of this study was to investigate if the 7–item Berg balance scale (BBS) 3–point, which is a short form of the BBS (SFBBS), has compatible psychometric properties in comparison with the original BBS, and also to study the concurrent validity using a 10-meter walk test (10mWT) and a timed up and go test (TUG), which are widely used with SFBBS in clinical settings. METHODS: A total of 255 patients who had experienced stroke participated in this cross-sectional study. We used results obtained from 188 patients who completed both 10mWT and TUG. The three levels in the center of the BBS were collapsed to a single level (i.e.,0-2-4) to form the SFBBS. The concurrent validity was assessed by computing the Spearman coefficients for correlation among outcome measures and in between each outcome measure and the SFBBS. As there were four outcomes, the corrected p-value for significant correlation was 0.013 (0.05/4). RESULTS: Spearman coefficients for correlations and evaluation instruments for concurrent validity revealed significantly high validity for both of SFBBS and BBS (r=0.944). 10mWT and TUG were −0.749 and −0.770 respectively, which are in the high margin and are statistically significant (p>0.000). CONCLUSION: SFBBS has sound psychometric properties for evaluating patients with stroke. Thus, we recommend the use of SFBBS in both clinical and research settings.

BACKGROUND: The objective of the current study was to determine whether there was an association between urinary albumin excretion and cardiovascular disease (CVD) risk by estimating the Framingham Risk Score (FRS) in postmenopausal women without diabetes. METHODS: This study was based on data from the Korea National Health and Nutrition Examination Survey, which was conducted by the Korean Ministry of Health and Welfare in 2011 to 2013. Data on 2,316 postmenopausal women from a total of 24,594 participants was included in the analysis. RESULTS: The mean FRS was significantly different in each of the urinary albumin to creatinine ratio (UACR) subgroups, and it increased with UACR. The FRS was 12.69±0.12 in the optimal group, 14.30±0.19 in the intermediate normal group, 14.62±0.26 in the high normal group, and 15.86±0.36 in the microalbuminuria group. After fully adjusting for potential confounding factors, high normal levels and microalbuminuria were significantly associated with the highest tertile of FRS ([odds ratio (OR), 1.642; 95% confidence interval (CI), 1.124 to 2.400] and [OR, 3.385; 95% CI, 2.088 to 5.488], respectively) compared with the optimal subgroup. High normal levels and microalbuminuria were also significantly associated with a ≥10% 10-year risk of CVD ([OR, 1.853; 95% CI, 1.122 to 3.060] and [OR, 2.831; 95% CI, 1.327 to 6.037], respectively) after adjusting for potential confounding covariates. CONCLUSION: Urinary albumin excretion reflects CVD risk in postmenopausal women without diabetes, and high normal levels and microalbuminuria were independently associated with a higher risk of CVD.

PURPOSE: To examine effects of a postnatal care program on self-efficacy, self-management, and glycemic control in women with gestational diabetes mellitus (GDM). METHODS: A non-equivalent control group non-synchronized quasi-experimental design was used. Sixty-two women with GDM were enrolled and assigned to either an experimental group (n=30) or a control group (n=32). The experimental group received an intervention which was postnatal care program for women with GDM. The postnatal care program for GDM included an individual education with leaflet and mobile web-based video with three times of telephone counseling. Effects of the intervention were measured with self-efficacy, self-management questionnaire, and a 75 g oral glucose tolerance test (75g OGTT). Statistical significance was examined using independent t-test and χ2-test. RESULTS: Although there was no significant difference in 75g OGTT (χ2=.11, p=.748) or self-management (t=−1.28, p=.206), there was a statistically significant increase in self-efficacy (t=−2.02, p=.048) in the experimental group compared to that in the control group. CONCLUSION: A postnatal care program is needed for women with GDM to improve their self-efficacy. Further studies are warranted to improve self-management and glycemic control through tailored education for GDM postpartum women.

PURPOSE: Many researchers have tried to develop animal models that mimic the human immune system, e.g. a humanized mouse model, to improve the engraftment of hematopoietic stem cells and develop human immune cells in an animal model. This study evaluated the feasibility of the cultured human umbilical cord blood (hUCB)-derived CD34(+) cells for cell expansion, in Rag2(-/-)gamma(c)(-/-) mice, and establish co-transplantation with human fetal thymus/liver tissue (Thy/Liv) under the kidney capsule. METHODS: Co-transplantation of hUCB-derived CD34(+) cells with Thy/Liv was performed. The hUCB-derived CD34(+) cells were prepared by freshly thawing (G1) and culturing for 7 days with two types of cytokine combinations (G2, G3). The CD45(+) cell populations were measured at 6, 8, 10 and 16 weeks in the peripheral blood. The splenocytes were cultured with mitogenic stimuli (PHA -L or IL-2) at 20 weeks post- transplantation, and the proliferation of human immune cells was evaluated. RESULTS: There were no significant differences in the human CD45(+) cell populations at 6, 8, 10 and 16 weeks post-transplantation between the groups. In the cultured splenocytes at 20 weeks post-transplant with PHA-L or IL-2, there was remarkable expansion of CD3(+) cells in the three groups. Although no CD19(+) cells were detected in the spleen, human Ig G was detected in the sera of these mice. CONCLUSION: The cultured and expanded hUCB-derived cells with cytokine combinations might be a feasible cell source in humanized mouse modeling. In addition, human immune cells can be reconstituted from the co-transplantation of Thy/Liv and cultured hUCB-derived CD34(+) cells.

Intraportal islet transplantation (IPIT) may potentially cure Type 1 diabetes mellitus; however, graft failure in the early post-transplantation period presents a major obstacle. In this study, we tested the ability of nicotinamide to prevent early islet destruction in a syngeneic mouse model. Mice (C57BL/6) with chemically-induced diabetes received intraportal transplants of syngeneic islet tissue in various doses. Islets were cultured for 24 h in medium with or without 10 mM nicotinamide supplementation. Following IPIT, islet function was confirmed by an intraperitoneal glucose tolerance test (IPGTT) and hepatectomy. The effects of nicotinamide were evaluated by blood glucose concentration, serum monocyte chemoattractant protein-1 (MCP-1) concentration, and immunohistology at 3 h and 24 h after IPIT. Among the various islet doses, an infusion of 300 syngeneic islets treated with nicotinamide exhibited the greatest differences in glucose tolerance between recipients of treated and untreated (i.e., control) islets. One day after 300 islet equivalent (IEQ) transplantation, islets treated with nicotinamide were better granulated than the untreated islets (P = 0.01), and the recipients displayed a slight decrease in serum MCP-1 concentration, as compared to controls. After 15 days, recipients of nicotinamide-pretreated islets showed higher levels of graft function (as measured by IPGTT) than controls. The pretreatment also prolonged graft survival (> 100 days) and function; these were confirmed by partial hepatectomy, which led to the recurrence of diabetes. Pretreatment of islet grafts with nicotinamide may prevent their deterioration on the early period following IPIT in a syngeneic mouse model.

Background:
Although the consumption of vitamin beverages has increased because of the recent interest in health and beauty, guidelines addressing appropriate consumption habits are lacking. Thus, the aim of this study was to investigate the erosive potential of several vitamin beverages and to propose guidelines for the appropriate intake of these drinks.
Methods:
Five vitamin beverages were selected after a pre-investigation of the current beverage market. Coca-Cola and mineral water were selected as the control beverages. The pH of the beverages was measured with a calibrated pH meter, and the titratable acidity (TA) was determined by using 1 M sodium hydroxide to reach pH 5.5 (TA5.5) and 7.0 (TA7.0). The screening method suggested by the International Organization for Standardization was used to measure pH variation (pH) by using an under-saturated hydroxyapatite solution to determine the difference between the initial and final pH of the screening solution. All measurements were performed in triplicate.
Results:
All vitamin beverages tested in this study exhibited a low pH (2.53∼2.99), similar to Coca-Cola, which is known to be a highly acidic beverage. The highest TA5.5 and TA7.0 values of the vitamin beverages were 7.03 ml and 8.81 ml, respectively. The largest change in pH determined by using the screening solution was found in Bacchus D (pH 1.44±0.05). The mean pH of the vitamin beverages was 1.12±0.29, which was higher than that of Coca-Cola (positive control, pH 0.58±0.05).
Conclusion
Vitamin beverages exhibited an erosive potential capable of damaging enamel surfaces. Therefore, the frequency of vitamin beverage intake should be limited, and individuals consuming these drinks should try to restore normal oral pH as quickly as possible.

OBJECTIVE: Association between home environment and the behavioral and neurocognitive development of children from a community childcare center for low-income families was examined (aged 6 to 12 years, n=155). METHODS: The parents performed a questionnaire on home environment (K-HOME-Q) to assess home environment including parenting attitude and the Child Behavior Checklist (K-CBCL). The children performed the Wechsler Intelligence (IQ) Scale, Stroop interference test (Stroop), word fluency test (WF), and design fluency test (DF) to assess their neurocognitive development. RESULTS: ‘Nurturing of Development’ and ‘Variety of Language Interaction’ scores from the K-HOME-Q, were inversely associated with total behavior problems, externalization, rule-breaking, and aggressive behavior subscales of K-CBCL, and ‘Emotional atmosphere’ and ‘Tolerance toward the child’ scores showed inverse associations with the total behavior problems, rule-breaking, aggressive behavior, and withdrawn/depressed subscales. Despite economic hardship, the mean scores of the neurocognitive tests were comparable to the average level of Korean children’s normative sample. However, ‘Nurturing of Development’ and ‘Tolerance toward the Child’ score of K-HOME-Q were associated with better executive function (IQ, WF, DF). CONCLUSION: These results suggest that parental stimulation of development and tolerant parenting attitude may offer protection against the negative effects of suboptimal economic environment on children’s behavior and neurocognitive development.

PURPOSE: Normal squamous cells do not exist in the orbit. Therefore squamous cell carcinoma of the orbit is rare and usually arises as a secondary tumor from distant metastasis or local invasion. The authors herein describe the first case of primary squamous cell carcinoma of the orbit in Korea. CASE SUMMARY: A 74-year-old female presented with a 2-month history of left upper eyelid swelling and ocular pain. On physical examination, a round, firm, fixed and tender mass was palpable in the superomedial side of the left orbit. Magnetic resonance imaging (MRI) showed 21 mm x 15 mm x 20 mm-sized irregular soft tissue mass with indistinct margin and peripheral enhancement in the superomedial portion of the left orbit, and incisional biopsy of the mass was performed. Histopathological examination showed clusters of squamous cells with polymorphic nuclei and interspersed keratin pearls, consistent with findings of well-differentiated squamous cell carcinoma. Despite extensive systemic work-up, there was no sign of extraorbital malignancy. The patient received left exenteration and adjuvant radiation therapy. Ten months after enucleation, a 12 mm x 14 mm sized firm mass developed on the left forehead, and excisional biopsy and frontalis rotational flap reconstruction were performed. Histopathological examination of the mass was consistent with well-differentiated squamous cell carcinoma. The patient remained alive 17 months after diagnosis without evidence of local recurrence or distant metastasis. CONCLUSIONS: Primary squamous cell carcinoma should be considered in the differential diagnosis of acutely progressing tumors of the orbit.

PURPOSE: This study was conducted to investigate the pulmonary cellular profiles and IL-8 levels in patients with post-measles wheezing. METHODS: Twelve previously healthy infants with a minimum of three episodes of wheezing after measles pneumonia(Measles wheezing, median age, 1.3 years) were recruited by a retrospective examination of hospital records. They underwent bronchoalveolar lavage(BAL) with flexible bronchoscopy, and high-resolution computed tomography(HRCT) with a mean six(1-15) months interval. Comparisons were made with seven normal controls(Control, median age: 7.4 years). BAL cell counts and differentials were determined. IL-8 levels also were measured by ELISA. RESULTS: The BAL cellular profiles were characterized by a significantly increased percentage of neutrophils in the Measles wheezing group(median 16.0%) compared to the control group(median 3.8%)(P<0.01). IL-8 levels were markedly increased in the Measles wheezing group(mean+/-SD, 512.7+/-324.0 pg/mL) compared to the control group(41.7+/-67.7 pg/mL)(P<0.01). Furthermore, IL-8 levels correlated significantly(r=0.816, P=0.001) with neutrophil percentages in BAL fluids in the Measles wheezing group. Abnormal HRCT findings were mosaic perfusion, bronchiectasis, bronchial wall thickening, and decreased vascularity. CONCLUSION: These results suggest that pulmonary neutrophils and IL-8 may play an important role in the pathogenesis of the post-measles wheezing.

PURPOSE: The aim of this study was to assess the diagnostic efficacy of noninvasive prenatal screening for trisomy 18 by assessing the levels of unmethylated-maspin (U-maspin) and fetal nuchal translucency (NT) thickness during the first trimester of pregnancy. MATERIALS AND METHODS: A nested case-control study was conducted using maternal plasma samples collected from 65 pregnant women carrying 11 fetuses with trisomy 18 and 54 normal fetuses. We compared the U-maspin levels, NT thicknesses, or a combination of both in the first trimester between the case and control groups. RESULTS: U-maspin levels and NT thickness were significantly elevated in the first trimester in pregnant women carrying fetuses with trisomy 18 when compared to those carrying normal fetuses (27.2 vs. 6.6 copies/mL, P<0.001 for U-maspin; 5.9 vs. 2.0mm, P<0.001 for NT). The sensitivities of the U-maspin levels and NT thickness in prenatal screening for fetal trisomy 18 were 90.9% and 90.9%, respectively, with a specificity of 98.1%. The combined U-maspin levels and NT thickness had a sensitivity of 100% in prenatal screening for fetal trisomy 18, with a specificity of 98.1%. CONCLUSION: A combination of U-maspin levels and NT thickness is highly efficacious for noninvasive prenatal screening of fetal trisomy 18 in the first trimester of pregnancy.
