Background: It is known that blood group antigens are related to the development of peptic ulcer and gastric carcinoma. Infections due to H. pylori are most widespread among the developing regions due to poor standard of public health. This study sought to determine the association of H. pylori with ABO blood groups, age, gender, and smoking status among inpatients at a public sector hospital in Karachi. Materials and Methods: A cross-sectional study was conducted at endoscopy suite at a public sector hospital in Karachi in the year 2011. All the symptomatic patients coming for upper GIT endoscopy were included in this study. Results: Biopsy for histopathology was taken from 93 patients, with an age range from 15-65 years. Age group of 15 to 20 years was found to be associated with H. pylori infection but without significance (p-value 0.83). In all, 36 (38.7%) turned out to be H. pylori positive with a significant male preponderance (p=0.04). Distribution of ABO blood groups in H. pylori positive group were A=31.4%, B=15.4%, AB=25.0% and O=53.7%, with a statistically significant link for blood group O (p=0.05). Rhesus factor was also compared but significant relationship was evident (p-value 0.73). Conclusions: This study demonstrated that H. pylori infection can be related to ABO blood group, middle age persons and male gender. People of blood group O are more prone to develop infection related gastritis, ulcers, and even perforations, so they should be more cautious against transmission of the bacterium.

Objectives: Calcium (Ca) is an insufficiently consumed nutrient, whereas phosphorus (P) intake has exceeded the recommended intake level in Korea over the past decade. The purpose of this study was to analyze dietary Ca and P intakes and their contribution rate according to dish groups. Methods: A 24-hour dietary recall survey of 640 healthy adults (aged 19-69 years) was undertaken twice in four Korean provinces. Dietary Ca and P intakes and their rates of contribution from 31 major dish groups were analyzed and compared by gender, age group, and region. Results: The average Ca and P intakes of the subjects were 542.1 ± 222.2 mg/d and 1,068.3 ± 329.0 mg/d, respectively. The intakes of Ca and P as percentages of recommended nutrients intake (RNI%) were 71.7 ± 29.8% and 152.6 ± 47%, respectively, and the percentages under the estimated average requirement were 60.3% for Ca and 3.8% for P. The RNI% of Ca was not significantly different between males and females, but was significantly higher in subjects in the sixties age group than in other age groups and was significantly lower in the Korean capital than in other regions. The RNI% of P did not significantly differ by gender or age groups, but it was significantly higher in the capital than in Gyeong-sang. The five major dish groups contributing to Ca intake (contribution rate) were milks/dairy products 69.2 ± 109.2 mg/d (12.6%), soups 55.6 ± 69.6 mg/d (10.1%), stir-fried foods 53.1 ± 70.7 mg/d (9.7%), stews 43.4 ± 85.4 mg/d (7.9%), and kimchi 38.4 ± 31.8 mg/d (7.0%). The five major dish group contributing to P intake (contribution rate) were cooked rice 160.7 ± 107.1 mg/d (14.9%), stir-fried foods 88.5 ± 89.4 mg/d (8.2%), soups 76.7 ± 85.8 mg/d (7.1%), one-dish meals 63.3 ± 94.4 mg/d (5.9%), and stews 62.6 ± 89.3 mg/d (5.8%). The dish groups contributing to Ca and P intakes differed somewhat by gender, age group, and region. Conclusions: Programs to improve the nutritional status of Ca and P intakes should consider the differences in Ca and P contribution rates by dish groups as well as by gender, age group, and region.

This study aimed to determine the seroprevalence and to identify risk factors associated with Neospora spp. infection in horses in Jordan. Management related data were collected from each farm and individual horses. Sera from 227 horses from 5 of 6 climatic regions in Jordan were analyzed for the presence of antibodies to Neospora spp. by ELISA kit. The study was performed during spring of 2010. The association between seropositivity and risk factors was analyzed. A total of 7 (3%) of 227 sera had antibodies for Neospora spp. There was a significant regional difference (P=0.018) between the 5 climatic regions. Positive cases were located in Amman and Irbid, while the other regions (Zarqa, Jordan Valley, and Wadi Mousa) had zero prevalence. The use of anthelmintics at least once a year resulted in a significant reduction of the seroprevalence to Neospora spp. (1.6% vs 9.8%). However, this might be a phenomenon by chance and a better hygiene since owners can invest in anthelmintics. Other risk factors such as age, gender, breed, usage, body condition score, grazing, presence of other animals mixed with the horses in the same property, and a history of previous diseases were not significantly associated with the seroprevalence to Neospora spp. infection. This is the first study to report on the presence of Neospora seropositive horses in Jordan. Further studies are warranted to better understand the role of certain risk factors in the transmission of Neospora spp. among horse population and to determine which Neospora spp. are responsible for the infection.

Purpose: The purpose of this study was to compare suicide mortality by region in South Korea. Method: Suicide mortality differentials were calculated for several mortality indicators by geographical regions from raw data of the cause of death from KNSO. Results: The results are as follows; the Crude suicide death rate was 22.63 per 100,000. The highest was in Kangwon showing 37.84% whereas, Chungnam, and Jeonbuk followed after. Suicide was 4.4% of all causes of death, but Inchon and Ulsan showed a higher proportion. The male suicide death rate was 31.12 per 100,000 and females 14.09. The ratio of gender suicide mortality was 2.21, per 100,000 and was the highest in Jeju. For age-specific suicide death rates, the rate increased as age advanced, showing 2.33 per 100,000 in 0-19years, 18.68 in 20-39, 30.48 in 40-59, 63.33 in 60 years and over. In Ulsan, Kangwon, and Inchon, age-specific suicide death rates of the 60 and over age group were higher than other regions, Daegu, Busan, and Kangwon showed a higher age-specific suicide mortality of the 40-59 age group, and Kangwon, Jeonnam, and Chungnam had a higher age-specific suicide mortality of the 20-39 age group. Conclusions: Suicide mortality differed by region. These results can be used for a regional health care plan and planning for suicide prevention by regions.

Purpose: This study was designed for identification of the main clinicopathological features of cysts in the oral and maxillofacial regions. Methods: A retrospective observational study was conducted on 164 patients who had been diagnosed with cyst of the jaw, from the database of 168 histopathological diagnoses at the Department of Oral and Maxillofacial Surgery of Busan Paik Hospital at Inje University, from January 2009 to December 2011. The subjects were treated and the following variables were recorded: gender, age, clinical signs and symptoms, histopathological distribution, treatment methods, and complications. A descriptive analysis of the study variables was performed using a chi-square test. Results: Among the 164 patients, there were more male than female patients (male-female ratio: 1.7:1). The most predominant ages were the 20s and 40s. Among the classes of pathological cysts, radicular cysts and dentigerous cysts were the most common, with incidences of 56.0% and 35.1%. Thirty-six percent of the patients had no symptoms; and of those who had symptoms, the main signs and symptoms were swelling (24.4%) and pain (17.1%). The most frequent management method was the combination operation, such as enucleation with or without extraction and apicoectomy of the causative teeth. Of the 164 patients, 13 had complications; and one patient who had been treated with enucleation with apicoectomy had a recurrent cyst. Conclusion: Using a chi-square test, no significant differences in prevalence were observed in relation to gender according to age. Comparative analysis of radicular and dentigerous cysts showed a significant difference in their prevalence according to their anatomical location, however, no significant differences in were observed in their incidence rates according to age.

Background: Smoking is a primary risk factor for cancer development. While most research has focused on smoking cigarettes, the increasing popularity of shisha or water pipe smoking has received less attention. This study measured the prevalence and risk factors for shisha and cigarette smoking and related knowledge. Materials and Methods: This cross-sectional analytical study was conducted in Shah Alam, Malaysia. Participants aged ${\geq}18years$ were selected from restaurants. Data regarding demographic variables, smoking patterns, and knowledge about shisha smoking were collected in local languages. Logistic regression was performed to assess risk factors. Results: Of 239 participants, 61.9 % were male and 99.2% revealed their smoking status. Some 57.4% were smokers: 50.7% only cigarettes, 5.9% only shisha and 42% both. Mean age of starting cigarette smoking was $17.5{\pm}2.4years$ and for shisha smoking $18.7{\pm}2.0years$. In a univariate model, male gender, age 33-52 years and monthly income > MYR 4,000 increased the risk and unemployment and being a student decreased the risk. In a multivariate model, male gender increased the risk of smoking, while being a student decreased the risk, adjusting for age and income. The perception of shisha being less harmful than cigarettes was present in 14.6% and 7.5% had the opinion that shisha is not harmful at all, while 21.7% said that it is less addictive than cigarettes, 39.7% said that shisha did not contain tar and nicotine, 34.3% said that it did not contain carbon monoxide and 24.3% thought that shisha did not cause health problems. Conclusions: Prevalence of shisha and cigarette smoking is high in the general population in Malaysia and knowledge about shisha smoking is relatively low. The findings of our study might have implications for understanding similarities and differences in incidence of shisha and cigarette smoking in other cultural/geographic regions.

This research was designed to examine the dietary habits and unbalanced diet of middle school students by gender and region. The survey was conducted using questionnaires on dietary habits and unbalanced diet administered to 726 students (urban: 367, rural: 359). The obesity index using BMI showed that the largest proportion of girls was 'underweight' in both regions, which showed a significant difference by region (p<0.001). Male students in urban areas prefer salty taste more than rural students (p<0.05). In urban areas, problems relating to dietary habits were 'unbalanced diet' and 'overeating' in male students and 'frequent snacks' and 'irregular mealtime' for female students (p<0.01). The frequencies of skipping breakfast (p<0.01), snack intake (p<0.001), eating out (p<0.001) and fast food consumption (p<0.001) were significantly higher in urban students than in rural students, and the reason for eating snacks was 'hungry' in urban students and 'habitually' and 'delicious' in rural students (p<0.01). Unbalanced diet was significantly higher in rural students compared with urban students (p<0.001) and male students compared with female students in urban (p<0.05), and the factors affecting dietary habits were mostly related to family. Male students in urban areas showed a significantly lower intake frequency of 'fish, tofu and beans' (p<0.05) and 'milk and yogurt' (p<0.05), but higher intake frequency of 'vegetables' (p<0.001) compared with female students. Male students in rural areas showed a significantly lower intake frequency of 'meat' (p<0.05) but higher intake frequency of 'milk and yogurt' (p<0.05) compared with female students. Urban students showed a significantly higher intake frequency of food groups compared with rural students. To conclude, desirable nutrition education on meal regularity, snack choice, and problems relating to unbalanced diet should be conducted in schools.

The colors of packaging of herbicides and non-selective herbicides on the market in Korea are defined as brown and red, respectively, according to the notification of RDA. The present study aimed to understand consumer's electroencephalographic (EEG) response when looking at brown and red colors of herbicide and non-selective herbicide packaging papers. The EEG cap was placed on the scalp of each participant (men and women, 10 to 20 years old) and white (control) - brown - white - red colors were sequentially displayed for 5 seconds using the computer monitor. The EEG was measured and statistical analysis was performed using SPSS. For the brown color of the herbicide, men showed a decrease in concentration and a distracting response due to a decrease in the ratio of mid beta to theta (RMT) and the spectral edge of frequency (SEF90). In women, an increase in the ratio of SMR to theta (RSMT) and the spectral edge frequency 50% of the alpha (ASEF) was observed in different brain regions and these EEG changes may enhance the relaxation, stabilization and awakening states of the brain. For the red color of the non-selective herbicide, ASEF increased psychological stability in men. In women, a decrease in absolute high beta (AHB) may associate with a decrease in attention state of the brain. Overall data of the present study clearly revealed that the colors of two herbicides showed significantly different EEG response and gender difference.

Purpose: The subcutaneous fat tissue is separated into 2 layers by the subcutaneous fascia: the superficial and deep fat layers. The two fat layers have different structures according to the body regions. The purpose of this study is to evaluate the distribution and pattern of the two fat layers in the human body by computed tomography (CT) and histological analysis according to age, sex, anatomical region, and body mass index (BMI). Methods: This study included 200 males and 200 females who underwent 64-channel dynamic CT in our hospital. The patients were divided into 5 groups according to 10 years of their ages separately in either male or female gender. The thickness of the superficial and deep fat layers was measured in the abdominal, pelvic, and femoral regions, and we analyzed the values. Statistical analyses were performed using SPSS software. The $3{\times}3$-cm whole fat layers were harvested from the same sites of 3 cadavers for histological examination, and one cadaver was dissected for gross evaluation. Results: The total thickness of subcutaneous fat tissue was greater in females than in males, and the ratio of the superficial fat layer to the whole fat layer was higher in females. The superficial fat layer became thinner with increasing age in males. As BMI increased, the total fat layer became thicker, and the superficial fat layer became thicker than the deep fat layer. On histological examination, the superficial fat layer had small adipose lobules and showed a densely distributed pattern in the abdominal region, whereas in the femoral region, it had large adipose lobules and showed a sparsely distributed pattern. There were no significant differences in the histological findings of the deep fat layer between the 3 body regions. Conclusion: Significant differences in histological findings of the two fat layers were found in relation to age, sex, anatomical region, and BMI. The superficial fat layer became thinner with increasing age in males, but it was constant in females. As BMI increased, the total thickness of subcutaneous fat tissue became greater, and the superficial fat layer became thicker than the deep fat layer. Our measurements can be used to understand the characteristics of the fat layers in relation to age, sex, anatomical region, and BMI.
