Objectives

The purpose of this study was to evaluate hypertension with simple anthropometry data related to obesity in Korean adults and identify whether age specific waist circumference (WC) may be a useful screening tool for determining hypertension.

Methods

Subjects (n = 571) were classified into 3 groups by age; young (18–39 years), middle aged (40–64 years), and old aged (≥ 65 years). Correlations between demographic and anthropometric parameters and hypertension were performed using Spearman correlation analysis. Logistic regression analysis and ROC (receiver operating characteristics) curves were also analyzed for correlations with hypertension.

Results

Spearman correlation analyses, age, gender, WC, and body mass index were positively correlated with hypertension. When logistic regression analysis was performed, increased age and increased WC was associated with a higher incidence of hypertension, although gender and body mass index were not significantly related to hypertension. In ROC analysis of WC for hypertension demonstrated that patients in the old age group showed higher WC cutoff value than patients in the young and middle aged groups.

Conclusion

The findings of this study demonstrate that WC may be a useful predictor of hypertension incidence among demographic and anthropometric factors in Korean adults. In addition, WC in the young population was more sensitive to the incidence of hypertension than in the elderly population.

Objectives

To evaluate the impact of 3 treatment regimens upon health-related quality of life and work productivity using patient-reported outcomes (PROs) in chronic hepatitis C infected patients: sofosbuvir (SOF) + daclatasvir (DCV); SOF + DCV + ribavirin (RBV); SOF + simeprevir (SMV).

Methods

4 questionnaires were used to evaluate PROs before, during and after treatment: Short Form-36 (SF-36), Chronic Liver Disease Questionnaire (CLDQ) - hepatitis C virus (HCV), Work Productivity and Activity Index, Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F).

Results

Of the global sample of 55 patients included in this study; SOF + DCV (n = 10); SOF + DCV + RBV (n = 29); SOF + SMV (n = 16) all had a statistically significant improvement in SF-36, CLDQ and FACIT-F scores during and post-treatment. No statistically significant differences in the PRO questionnaire values were observed between the distinct treatment regimens. The SOF and SMV patient groups presented higher mean PRO variations during and post-treatment, compared to the other groups: SF-36 functional capacity (16.1); SF-36 mental health (21.4); CLDQ activity (1.8); CLDQ emotional function (1.2); FACIT-F physical well-being (8.0); Total FACIT-F (21.6).

Conclusion

Treatment with SOF + DCV, with or without RBV, results in an improved PRO similar to treatment with SOF + SMV in chronic hepatitis C patients.

Objectives

The aims of this meta-analysis were to examine intervention methods of qualitatively, well-designed studies from the past 10 years for treating visuo-spatial neglect (VSN) in patients who had suffered a stroke, and to evaluate the combined effects of intervention.

Methods

Studies published between 2008 and 2017 on the theme of VSN were collected from PubMed, CINAHL, and MEDLINE, representative academic databases and search engines. The PEDro scale was used for evaluating the quality of methodology. The sample size, mean, and standard deviation of identified studies were used for meta-analysis.

Results

Eight studies were selected for analysis. The PEDro scores of the selected studies were ≥ 7, with 237 subjects analyzed. The results of intervention were classified into “mental function” and “activity and participation” based on the International Classification of Functioning, Disability and Health. The analyzed effect sizes for combined outcomes, mental function and, activity and participation, were 0.728 (medium effect size), 0.850 (large effect size), and 0.536 (medium effect size), respectively.

Conclusion

Intervention methods for treating VSN had a short-term effect on cognitive function (visual perception). In particular, non-invasive brain stimulation therapy showed a large effect size for VSN treatment.

Objectives

Investigations into foodborne illness, potentially caused by Kudoa septempunctata, has been ongoing in Korea since 2015. However, epidemiological analysis reporting and positive K septempunctata detection in feces in Korea has been limited. The aim of this study was to provide epidemiologic data analysis of possible food poisoning caused by K septempunctata in Korea.

Methods

This study reviewed 16 Kudoa outbreak investigation reports, including suspected cases between 2015 and 2016 in Gyeonggi province, Korea. Suspected Kudoa foodborne illness outbreak was defined as “evidence of K septempunctata in at least one sample.” The time and place of outbreak, patient symptoms and Kudoa (+) detection rate in feces was analyzed.

Results

Kudoa foodborne illness outbreaks occurred in most patients in August (22.6%) and in most outbreaks in April (25%). The attack rate was 53.9% and the average attack rate in patients who had consumed olive flounder was 64.7%. The average incubation period was 4.3 hours per outbreak. Diarrhea was the most common symptom which was reported by 91.5% patients. The Kudoa (+) detection rate in feces was 69.2% of cases.

Conclusion

Monthly distribution of Kudoa foodborne illness was different from previous studies. The Kudoa (+) detection rate in feces decreased rapidly between 25.5 and 28.5 hours of the time interval from food intake to epidemiologic survey. To identify effective period of time of investigation, we believe additional study with extended number of cases is necessary.

Objectives

The aims of this study were to investigate the proportion of households facing catastrophic health expenditures based on household income quintiles, and to analyze the relationship between expenditures and household income quintile decline.

Methods

Study data were obtained from an annually conducted survey of the 2012–2013 Korean health panel. There were 12,909 subjects aged 20–64 years from economically active households, whose income quintile remained unchanged or declined by more than one quintile from 2012 to 2013. Logistic regression analysis was performed to determine whether catastrophic health expenditures in 2012 were related to more than one quintile income decline in 2013.

Results

Households facing catastrophic health expenditures of ≥ 40%, ≥ 30%, and ≥ 10% of a household’s capacity to pay, were 1.58 times (p < 0.003), 1.75 times (p < 0.000), and 1.23 times (p < 0.001) more likely to face a decline in income quintile, respectively.

Conclusion

Over a 1 year period, the proportion of households facing more than one quintile income decline was 16.4%, while 2.1% to 2.5% of households in Korea faced catastrophic health expenditures. Catastrophic health expenditure experienced in 2012 was significantly associated with income quintile decline 1 year later. Therefore, lowering the proportion of households with catastrophic health expenditure may reduce the proportion of households with income quintiles decline.

Objectives

Leishmania parasites are the causative agents of leishmaniasis. The Visceral leishmaniasis (VL) form of the disease is fatal if not treated in most cases. This study examined the epidemiological aspects of VL in two southwest counties of Iran.

Methods

This was a retrospective study of hospitalized patients with a laboratory confirmation of VL from Larestan and Ghiro-Karzin Counties.

Results

For Larestan county, a decline in the incidence of VL has been observed from 2004 to 2015. Significantly more males (n = 14) than females (n = 6) were infected with VL in this county (p < 0.05), >95% of cases in children under 5 years of age. In Ghiro-Karzin county, the results were similar to a decline in VL infection from 2004 to 2015, and slightly more males (n = 14) than females (n = 11). Similarly, the majority of the patients infected with VL were children under 5 years old (88%).

Conclusion

The results from this study indicate that although the incidence of VL infection has reduced over time, VL was more prevalent in boys under 5 years old, suggesting that more attention to controlling the parasite and its vector are required.

Objectives

Over the past few decades, the prevalence of cesarean sections (CS) have risen dramatically worldwide, particularly in Iran. The aim of this study was to determine the prevalence of CS in Tehran, and to examine the associated risk factors.

Methods

A cross-sectional study of 4,308 pregnant women with singleton live-births in Tehran, Iran, between July 6–21, 2015 was performed. Multilevel logistic regression analysis was performed using demographic and obstetrical variables at the first level, and hospitals as a variable at the second level.

Results

The incidence of CS was 72.0%. Multivariate analysis showed a significant relationship between CS and the mother’s age, socioeconomic status, body mass index, parity, type of pregnancy, preeclampsia, infant height, and baby’s head circumference. The intra-class correlation using the second level variable, the hospital was 0.292, indicating approximately 29.2% of the total variation in the response variable accounted for by the hospital.

Conclusion

The incidence of CS was substantially higher than other countries. Therefore, educational and psychological interventions are necessary to reduce CS rates amongst pregnant Iranian women.
