Visceral leishmaniasis (VL) or kala-azar mainly affects children in endemic areas. This study was conducted to determine the seroprevalence of VL using direct agglutination test (DAT) in children living in rural districts of Alborz Province located 30 km from Tehran capital city of Iran. Multi-stage cluster random sampling was applied. Blood samples were randomly collected from 1,007 children under 10 years of age in the clusters. A total of 37 (3.7%) of the studied population showed anti-Leishmania infantum antibodies with titers of ${\geq}1:800$. There was a significant association between positive sera and various parts of the rural areas of Alborz Province (P<0.002). Two children with anti-Leishmania infantum antibodies titers of ${\geq}1:3,200$ indicated kala-azar clinical features and treated with anti-leishmaniasis drugs in pediatric hospital. The findings of this study indicated that Leishmania infection is prevalent in rural areas of Alborz Province. Therefore, it is necessary to increase the awareness and alertness among physicians and public health managers, particularly in high-risk rural areas of the province in Iran.

Objectives: The prevalence of hypertension in Korean rural elderly was significantly higher than that of the general population. Determining the potential risk factors of hypertension would be useful for managing and improving the treatment and prevention of hypertension in rural areas. Methods: We studied 336 elderly individuals 110 males, 226 females) aged between 65 years and 95 years residing in the rural area, S-gun Jeonbuk. Health-related habits, frequency of intake of food groups, nutrient intakes, anthropometric and biochemical measurements were assessed. Subjects were defined as hypertensive if SBP was ${\geq}140mmHg$ or if DBP was ${\geq}90mmHg$ or take an antihypertensive drug. Results: The rate of prevalence of hypertension in the study group was 51.8% (male 40.0%, female 57.5%). The risk of occurrence of hypertension was higher among females (OR, 1.98), 75 years old or older (OR, 1.62), BMI ${\geq}25kg/m^2$ (OR, 2.84), acceptable range (upper end) of body fat (OR, 2.29) and unhealthy (too high) range of body fat (OR, 3.28), hypertriglyceridemia (OR, 2.17) and hypercholesterolemia (OR, 5.42), low protein intakes (OR, 1.78). However, health related habits, frequencies of intake of food groups and most nutrient intakes except for protein did not show any significant relationship with the occurrence of hypertension. Conclusions: To reduce the risk of occurrence of hypertension among elderly individuals in rural areas, it is needed to avoid increase of body fat, 25 or higher BMI ($kg/m^2$) and hyperlipidemia and low intake of proteins.

The present study analyzes the role of Lactic Acid Bacteria Mixture (LBM) on improving rye silage quality. Rye of four different stages (Booting, Heading, Flowering, and Late flowering) was collected and silage was prepared. The nutrient profile analysis of experimental silage groups showed no significant changes between control and LBM inoculation. Interestingly, the pH of rye silage in LBM treatments showed significant reduction than control (p<0.05) in all stages of rye silage. However, lowest pH (3.69) resulted on booting stage among other stages of rye. Subsequently significant lactic acid production was noted in all stages of LBM inoculation than control. Conversely maximum lactic acid production of (5.33%DM) was noted at booting stage followed by (4.86%DM) in heading stage. Further the lactic acid bacterial (LAB) count in LBM inoculated group showed significant increase than control. Similarly, the silage of booting stage group registered maximum LAB population ($63.7{\times}10^6CFU/g$) after that heading stage ($32.3{\times}10^6CFU/g$). Further significant reduction in yeast growth and no fungal growth was noted in all LPM treatment groups. Hence, LBM inoculants could be a better additive for improving rye silage quality.

BACKGROUND/OBJECTIVES: The objective of this study was to compare dietary habits and mental health among middle school students in urban and rural areas based on bedtime, and to provide evidence supporting appropriate bedtime for Korean middle school students in relation to their healthy dietary habits and mental well-being. SUBJECTS/METHODS: The study population consisted of 25,681 second-year middle school students who participated in the Korea Youth Risk Behavior Survey in 2020-2022. Participants were asked about their bedtime and wake-up time during the past 7 days and were classified into five categories. The study compared the general characteristics, academic factors, dietary habits, and mental health of urban and rural students based on their bedtime. RESULTS: Bedtime was found to be later in the following order: urban female students, rural female students, urban male students, and rural male students. As bedtime got later, the rates of smoking and alcohol consumption increased. Students who went to bed before 11 p.m. had lower academic performance, while rural male students who went to bed after 2 a.m. had lower academic performance. Later bedtime was associated with increased smartphone usage, skipping breakfast, consuming fast food, and drinking carbonated beverages. Later bedtime was also associated with higher perceived stress levels, particularly among students who went to bed after 2 a.m., higher rates of suicidal ideation, experiencing sadness and despair, as well as the prevalence of clinically significant anxiety disorders. CONCLUSION: These results suggest that middle school students who go to bed too late have higher rates of smoking and alcohol drinking, as well as unhealthy eating habits, stress, suicidal ideation, sadness, and anxiety. Therefore, it is necessary to provide educational and social institutional support to promote adequate sleep for the health of adolescents.

Plant-based, grain-free, and gluten-free diets have been the focus of recent research, as part of the premiumization trend in dog food. However, the lack of comprehensive information regarding carbohydrates in dog food makes it difficult to produce nutritionally balanced meals. Therefore, we aimed to evaluate the nutritional value of carbohydrate ingredients commonly used in commercial dog foods. First, using data from Euromonitor, we investigated the trends in the dry dog food industry and analyzed the annual volume of dry dog food sales, as well as the dog population from 2010 to 2021 in Korea. The growth of the market was greatest in 2021, when the total value of sales of premium dry dog food was 254.3 billion KRW (Korean won) more than in 2010. In addition, sales of dry dog food by age category were marked by a significant increase (404.8%) in the market for dry food for senior dogs. Second, we examined the frequency of carbohydrate ingredients used in dry dog food and conducted a proximate analysis of the top 10 most frequently used ingredients. Subsequently, we analyzed the crude protein, crude fat, and nitrogen-free extract in the carbohydrate ingredients based on dry matter (DM) and calculated the ratio of metabolic energy content supplied from each nutrient in the carbohydrate ingredients. The ratio of metabolic energy content in the carbohydrate ingredients indicated that mung beans had the highest crude protein content (31.3%), whereas oats exhibited the highest crude fat content (23.3%). Sweet potatoes had the highest nitrogen-free extract content, measuring at 93.6%. The results of this study are expected to provide a valuable foundation for the growth and development of the domestic dog food industry, while also contributing to a deeper understanding of the specific role of each ingredient as a carbohydrate source.

본 논문에서는 중국 개혁기간중 농업 집단체의 사회보장 기능이 점차 가족에게로 넘겨지는 과정을 연구하였다. 집단농업이 해체되고 시장사회주의 체제가 도입된 가운데 중국 농촌은 전반적으로 생산성이 향상 되었으나, 안정된 사회,경제적 기반을 잃은 상당수 농가들의 복지수요가 증가되는 결과를 가져왔다. 개혁이전의 시기의 사회복지는 집단 생산 및 평등배분을 통한 경제과정적 방책이 중심이었기 때문에 농업의 탈집단화는 곧 사회복지제도의 근본적 위기를 의미했다. 이같은 상황에서 재정적 어려움을 겪고 있는 중국 정부는 농촌가족의 전통적인 자체사회보장기능을 부활, 강화시키기위해 노력해 왔다. 본 연구는 이 같은 국가의 가족에 대한 현재 관계를 일반 복지 정책의 변화 및 식량조달, 의료, 노후보장의 측면에서 분석하였다.
