BACKGROUND: This study was carried out to examine the trends of government-supported health promotion research projects conducted in Korea over the past 12 years. METHODS: Research type, area of interest, organization, and expense of 726 research projects conducted from 1998 to 2009 were examined and the health promotion content analyzed. RESULTS: In Korea, 361 health policy researches (HPR) and 365 general health researches (GHR) were supported by the government during the defined time period. A total of 60.5 health promotion research were conducted annually with a total amount of 27.1 billion won provided (2.26 billion won per year). With the average research project lasting 8.5 months, HPR (7.7 months) projects were completed sooner than GHR (9.2 months). Those who majored in preventive medicine completed 177 research (24.4%), the most number of research projects, followed by public health (22.5%), and family medicine (15.6%). There were 641 health promotion research projects done mostly on policies, legal systems, and grasping current conditions, and only 85 (11.7%) clinical test research on the development or effects of health promotion programs. CONCLUSIONS: HPR have been increasing annually. However, our study could not be certain of how close the studies were to the government's health promotion policies. Furthermore, the main health promotion area, 'healthy living', was not researched as often as should be. Additionally, to improve applicability of the research projects, interdisciplinary cooperation should be promoted.

Malposition of the extracorporeal membrane oxygenation (ECMO) venous cannula in the azygos vein is not frequently reported. We hereby present such a case, which occurred in a neonate with right-sided congenital diaphragmatic hernia. Despite ECMO application, neither adequate flow nor sufficient oxygenation was achieved. On the cross-table lateral chest radiograph, the cannula tip was identified posterior to the heart silhouette, which implied malposition of the cannula in the azygos vein. After repositioning the cannula, the target flow and oxygenation were successfully achieved. When sufficient venous flow is not achieved, as in our case, clinicians should be alerted so they can identify the cannula tip location on lateral chest radiograph and confirm whether malposition in the azygos vein is the cause of the ineffective ECMO.

OBJECTIVES: This study was conducted to examine the effects of mobile health (mHealth), using mobile phones as an intervention for weight loss in obese adults. METHODS: An electronic search was carried out using multiple databases. A meta-analysis of selected studies was performed. The effects of mHealth were analyzed using changes in body weight and body mass index (BMI). RESULTS: We identified 20 randomized controlled trials (RCTs) involving 2,318 participants who fit our inclusion criteria. The meta-analysis showed that body weight was reduced with a weighted mean difference (WMD) of −2.35 kg (95% confidence interval [CI], −2.84 to −1.87). An examination of the impact of duration of intervention showed that weight loss was greater after 6 months of mHealth (WMD = −2.66 kg) than between three and four months (WMD = −2.25 kg); it was maintained for up to 9 months (WMD = −2.62 kg). At 12 months, weight loss was reduced to a WMD of −1.23 kg. BMI decreased with a WMD of −0.77 kg/m2 (95% CI, −1.01 to −0.52). BMI changes were not statistically significant at 3 months (WMD = −1.10 kg/m2), but they were statistically significant at 6 months (WMD = −0.67 kg/m2). CONCLUSIONS: The use of mHealth for obese adults showed a modest short-term effect on body weight and BMI. Although the weight loss associated with mHealth did not meet the recommendation of the Scottish Intercollegiate Guideline Network, which considers a reduction of approximately 5 to 10 kg of the initial body weight as a successful intervention. Well-designed RCTs are needed to reveal the effects of mHealth interventions.

PURPOSE: The purpose of this study was to investigate the health status and nutritional condition of children living in a low-income community through anthropometric, laboratory evaluation. METHODS: A community-based survey identified children below 15 years living in a low-income community. Their weight, height, visual acuity, hearing level and dental status were measured. Blood sample were obtained on June and July, 2004. Hemoglobin, serum cholesterol, Hepatitis B antigen/antibody, AST and ALT were measured. RESULTS: A total of 285 students(M:F=141:144) aged 6 to 14 years were included in this study. The heights and weights in some grades were smaller than controls. The prevalence of obesity was 10.6 percent in males and 10.7 percent in females. The prevalence of abnormal visual acuity, hearing impairments and dental carries were 20.5 percent, 0.3 percent and 69.4 percent. The prevalence of anemia was 10.1 percent. Serum total cholesterol was over 200 mg/dL in 7 percent. They complained of abdominal pain(22.1 percent) and headache(17.1 percent). Hyperthyroidism, cataract, neurofibromatosis, severe atopic dermatitis, ventricular septal defect, strabismus and inguinal hernia were newly diagnosed. CONCLUSION: Mean heights and weights of children in the low-income community were smaller than controls. The prevalence of abnormal visual acuity, hearing impairment and dental carries were higher than in the 2003 national health survey. Additional research is needed to evaluate the health status of the low-income community.

BACKGROUND: Standard solution-phase PCR cannot localize the amplified DNA products in cells or tissue sections. Recently, in situ PCR technique which combines PCR with in situ hybridization was developed and applied to detect target DNA or gene expression in the tissue sections. OBJECTIVE: The purpose of this study was to detect the presence of HSV type-1 DNA in herpes simplex lesions by using hot start PCR in situ hybridization and hot start in situ PCR and to compare the sensitivity and specificity of the two methods. The sensitivity and specificity of multiple overlapping primers and a single primer pair in hot start in situ PCR were also compared. METHODS: We performed hot start PCR in situ hybridization and in situ PCR with multiple overlapping primers, and hot start in situ PCR with a single primer pair in paraffin-embedded, formalin-fixed tissues. RESULTS: HSV type-1 DNA was detected in 4 (80%) of.5 cases of herpes simplex and negative in all cases of herpes zoster, verruca vulgaris, and normal skins. One negative case of herpes simplex could not be detected by HSV type-1 specific primers because it might be caused by HSV type-2. There was no difference in the sensitivity, specificity, and intensity of signals between the three methods. CONCLUSION: Hot start in situ PCR with a single primer pair is a simpler, easier, and more rapid technique for detecting the HSV type-1 DNA in lesional tissue sections with similar sensitivity and specificity than hot start PCR in situ hybridization and hot start in situ PCR using multiple overlapping primers.

PURPOSE: The purpose of this study was to determine whether upright position is effective in labor through systematic review in randomized controlled trials. METHODS: We established the PICO (Patient-Intervention-Comparator-Outcome) strategy, and reviewed 282 literatures from national and international electronic databases, and finally selected 9 references based on inclusion and exclusion criteria. We evaluated the quality of references and carried out a meta-analysis. RESULTS: The maternal outcomes showed that the duration of their second-stage labor was 2.29 minutes shorter than that of the women in the recumbent position, and were less likely to have episiotomy. The other outcomes, including the mode of delivery, blood loss, hemoglobin level, use of oxytocin, use of analgesics, and perineal laceration, did not differ between the groups. The fetal heart rate abnormality occurred less than in the control group. The Apgar scores of the groups did not differ. CONCLUSION: There is evidence that an upright position in the second stage of labor reduces the duration of the second stage of labor, the incidence of episiotomy, and an abnormal fetal heart rate.

BACKGROUND: Recent restriction enclonuclease analysis studies hsve revealed that MCV DNA can be classified into two major types, designated MCV-1 and MCV-2, by th:ir restriction enzyme cleavsge patterns. In earlier reports of MCV DNA analysis, MCV-2 was the main virus type found in genital lesions. However many recent studies cienied the relationship between virus type and anatomical distribution. OBJECTIVE: The purpose of this study was to examine the ratio of MCV-l to MCV-2 in Korean isolates of MCV DNA and the relationship between MCV subtypes and with clinical features such as anatomical location, age, sex, numiber of lesions, and atopic dermatitis. METHODS: MCV DNA extrated from 112 cases of Korean patients waa examined by restriction endonuclease analysis using Brtm HI. RESULTS: 1. MCV-1 was found in 108 of 112 (96.4%) patients and MCV-2 in of 112 (3.6%) patients. The ratio of MCV-1 to MCV-2 wss 28:1. 2. There was no significant ciprrelation between MCV subtypes and the age, sex, number of lesions, atopic dermatitis, and anatoimic loction. 3. Lesions induced by MCV-1 MCV-2 were indistinguishable on the brsis of size and form. CONCLUSION: This study showis that the ratio of MCV-1 to MCV-2 was 28:1 in Korean molluscum contagiosum patients and there was no relationship between MCV subtyies and lesional morphology or snatomical distribution.

BACKGROUND: Propofol, an intravenous anesthetic agent, is known to have potential beneficial cardiac effects through a cardiac L-type calcium channel blocking effect and free radical scavenging activities in a number of myocardial stunning models at clinical concentrations. We investigated the effect of high doses of propofol on myocardium in the isolated rat heart to find out whether it has a cardiac protective effect on a normal, not stunning, conditioned heart. METHODS: Twenty male Sprague-Dawley rats were put under general anesthesia to monitor the heart and perfused with a modified Krebs solution with a Langendorff model. After 30 minutes of stabilization, isolated rat hearts were given 0.5, 1, 5, 10, 50, 100 and 250 micrometer of propofol in an increasing manner for 10 minutes, respectively. At every period, left ventricular pressure, dp/dt, heart rate and coronary flow were recorded and Na+, K+, Ca2+, Mg2+ and protein leakage in the effluent perfusate were measured to observe the myocardial cell damage. RESULTS: Significant negative inotropic and chronotropic effects were seen at higher than 100 micrometer. Propofol dose-dependently increased coronary flow at concentrations of 100 micrometer or lower. Marked potassium and protein leakage in the effluent perfusate were found at a higher concentration of 100 micrometer propofol. CONCLSIONS: These findings suggest that a high dose of propofol exerts direct myocardial depression and myocardial cell damage, instead of a protective effect, in the isolated rat heart.
