Determinants of health care seeking behavior for childhood infectious diseases and malnutrition: A slum-based survey from Bangladesh.

This study aimed to explore the magnitude and determinants of health care seeking behaviors for common infectious disease and malnutrition among Bangladeshi under-five children living in slum areas. A cross-sectional study of 300 children-caregiver dyads was conducted in an urban slum of Bangladesh. Data were collected via a structured questionnaire with accompanying anthropometric assessments of children administered by research staff. Multiple logistic regression was employed to identify associated factors of health care seeking behaviors. Only 44.7% and 13.0% of respondents sought care for childhood infectious diseases and malnutrition, respectively. Being a male child, 2-5 years old, having ≤5 family members, monthly family income >125$, and living in close proximity to a health facility were found to be potential determinants of health care seeking behavior for childhood infectious diseases. Mother/caregivers with poor nutritional information knowledge and who had a child 2-5 years old reported engaging in less care seeking behaviors regarding their child's malnutrition compared to their counterparts. Caregivers of children under the age of 5 years old reported low participation in health care seeking behaviors in relation to childhood infectious disease and malnutrition. Families living in slums require additional support targeting health and nutritional educational programs.

Nutritional and in vitro antioxidant activity analyses of formulated soymilk dessert.

Soymilk (SM) is nutritionally nearly equal to milk from cows and is free of cholesterol, gluten, and lactose. This study's objective was to formulate a cholesterol-free soymilk dessert (SOD) and compare it's to commercial desserts (CODs). Results indicated that the CODs contain substantial amounts of cholesterol while SOD does not. Soymilk dessert has more protein, and vitamin E than CODs, but less fat and calcium. In addition, the result also highlighted that SOD has higher number of amino acids compared to CODs. The total antioxidant, flavonoids and phenolics content of SOD were significantly higher than CODs. Furthermore, the in vitro antioxidant activity of SOD and CODs by DPPH and ABTS methods revealed that the IC50 of SODs significantly (p < 0.001) lower than CODs, and lower IC50 indicated the higher free radical scavenging power of SODs than CODs. These findings indicated that this non-dairy SOD may provide beneficial protein, as well as minerals, and antioxidants to support the body's various physiological functions.

Impact of gamma radiation, potassium sorbate and low temperature on shrimp (Penaeus monodon) preservation.

The objective this study was to assess the effect of gamma radiation and 2% potassium sorbate with low temperature (4 °C) for shrimp (Penaeus monodon) preservation. Fresh samples were prepared for treatment with gamma radiation at 1.0 and 1.5 kGy doses and potassium sorbate (2%) soaked for 30 s (PS 30 s) and 60 s (PS 60 s). Organoleptic score (OS), biochemical composition and microbiological analysis were performed to evaluate the shelf-life extension and quality changes during the storage periods. Data showed that combination treatment of gamma irradiation at 1.5 kGy with low temperature was the most effective in extending shelf-life of shrimp. The isolated bacteria associated with shrimp samples were identified through PCR technique. Antibiotic sensitivity test was examined using ten commonly used antibiotics against these pathogenic isolates. Gentamicin and Imipenem showed up to 50% resistance on Gram-positive (Bacillus cereus and Staphylococcus aureus). This study indicates that gamma irradiation treatment with low temperature was most effective way for shelf-life extension of shrimp which might reduce the wastage of this important nutritional source.

Depressive symptoms associated with loneliness and physical activities among graduate university students in Bangladesh: findings from a cross-sectional pilot study.

In low-resource settings like Bangladesh, there is a dearth of research on the mental health of university students. This pilot study aimed to identify the prevalence of depressive symptoms, loneliness, and physical activities as well as the associated factors of depressive symptoms among graduate students in a public university of Bangladesh. This cross-sectional study was carried out among 323 graduate students between February 2019 and May 2019. By the convenience sampling technique, data were collected by a pretested, structured questionnaire. Depressive symptoms were assessed by the validated Patient Health Questionnaire-9 (PHQ-9) tool with a cut-off score of ≥10 vs. less; University of California, Los Angeles (UCLA) loneliness scale was applied to assess loneliness, International Physical Activity Questionnaire (IPAQ) scale was used to measure physical activity level. The overall prevalence of depressive symptoms was 52% and about 43% of participants felt most lonely. About 32.8% of students were involved in low physical activity. Being female, from lower income families, having poor academic performance, experiencing shorter sleep time, lower physical activity, and being lonely were potential risk factors for depressive symptoms among graduate university students. A positive correlation was found between loneliness and depressive symptoms of students (r = 0.367, p < 0.001). The higher prevalence of depressive symptoms among Bangladeshi graduate university students suggests the need for situation analysis, confirmatory clinical diagnosis, in-depth qualitative explorations, and large-scale surveys to explore the burden of such disorders and design appropriate low-intensity interventions like implementing student counselling service, offering mental assistance or other mental health support program in the country.
