Acceptability of home fortification with multiple micro-nutrients among Sri Lankan children.

Micronutrient deficiencies are mostly hidden; clinically less visible compared to macronutrient deficiencies. Food fortification with multiple micronutrients (MMN) is provided for children between 6-23 months, daily for two months at three-time points. We assessed the acceptance and adherence of this nutritional intervention in an urban community setting in Sri Lanka. This cross-sectional study enrolled caregivers of children aged 7 to 23 months with a cluster sampling method. Caregivers ' acceptance of taste and smell, health gains, ease of use, and need perception (Cronbach's reliability: 0.801) were assessed. Also, anemia knowledge (Cronbach's reliability: 0.642), MMN knowledge, and reported adherence (number of sachets consumed per month) were evaluated through a self-administered questionnaire. Adequate adherence was defined as the use of ≥80% sachets. The univariate and multivariate statistical analysis examined the association of acceptability, adherence, and anemia knowledge with independent variables (socio-demographic, household characteristics, and knowledge). The survey included 153 respondents. The Median (range) age of children was 12 months (7-23). The mean (SD) acceptability score was 66.82% (9.78%). Acceptance of sensory qualities (smell/taste) had a lower score than perceived health benefit. Most consumed MMN adequately (72.5%). The mean (SD) anemia knowledge score was 62.20% (25.79%). In multivariate analysis, child's age (OR: -0.360, 95% CI:-0.510,-0.211) and father's education (OR: 2.148, 95% CI: 0.439, 3.857) were independently associated with acceptability. Child's age (OR: -0.108, 95% CI:0.818, 0.985), anemia knowledge (OR:0.016, 95% CI: 1.003, 1.031) and acceptability (OR:0.236, 95% CI:1.140, 1.406) were significant determinants of adherence. Anemia knowledge was significantly associated with the mother's education and household income when adjusted. In conclusion, unpleasant smell/taste and daily schedule were reported as barriers to MMN use. Yet, perception and trust regarding health benefits were encouraging. Reported adherence was somewhat high. Improving acceptability and anemia knowledge could enhance adherence further in this population.

In vivo efficacy of calcium phosphate-based synthetic-bone-mineral on bone loss resulting from estrogen and mineral deficiencies.

Osteopenia and osteoporosis affect over 40 million US adults 50 years and older. Both diseases are strongly influenced by estrogen and nutritional-mineral deficiencies. This study investigates the efficacy of orally delivered synthetic-bone-mineral (SBM), a newly developed calcium phosphate based biomaterial, on reversing bone loss induced by these two critical deficiencies. Thirty 3-month-old female rats were randomly allocated to either control-sham surgery on normal diet; or one of the four experimental groups: Sham surgery on a low mineral diet (LMD), ovariectomized (OVX) on LMD, OVX on LMD with SBM with/without fluoride (F). The rats were sacrificed after 6 months, at 9-month-old. After 6 months, although all groups lost bone mineral density relative to controls, the supplemented OVX rats showed higher bone mineral density than their unsupplemented counterparts. The 2 SBM supplemented groups improved bone loading capacity by 28.1 and 35.4% compared to the OVX LMD group. Bones from supplemented rats exhibited higher inorganic/organic ratios. The addition of F did not have a significant influence on bone loss. Our findings suggest that SBM supplement is effective in maintaining bone health and offsetting the deleterious effects of estrogen and/or mineral deficiencies on bone density, microarchitecture, and strength.

Structure-based virtual screening for plant-derived SdiA-selective ligands as potential antivirulent agents against uropathogenic Escherichia coli.

The uropathogenic Escherichia coli pathogenecity is affected by quorum sensing transcriptional regulator SdiA. In this study, in vitro characterization of the active principles that could potentially antagonize with SdiA from the Melia dubia bark extracts has been described. After in vitro assays carried out to evaluate the inhibitory activities against the uropathogenic E. coli, the ethanolic extract (30 mg/ml) which showed the strongest suppression of haemolysis, swarming motility, hydrophobicity and biofilm formation, was subjected to GC-MS analysis and an array of 40 unrelated compounds was identified. Docking studies was conducted to screen for plant-based SdiA inhibitors. Five hits were assessed for their binding profiles and 7-(1-bromoethyl)-3, 3-dimethyl-bicyclo [4.1.0]heptan-2-one showed 66.95% binding ability with respect to C(8)HSL.

Evaluation of anti-pyretic potential of Ficus racemosa bark.

A study was carried out to evaluate the anti-pyretic effect of a methanol extract of stem bark of Ficus racemosa Linn. (MEFR) on normal body temperature and yeast-induced pyrexia in albino rats. A yeast suspension (10 ml/kg body wt.) increased rectal temperature 19 h after subcutaneous injection. The MEFR, at doses of 100, 200 and 300 mg/kg body wt. p.o., showed significant dose-dependent reduction in normal body temperature and yeast-provoked elevated temperature. The effect extended up to 5 h after drug administration. The anti-pyretic effect of MEFR was comparable to that of paracetamol (150 mg/kg body wt., p.o.), a standard anti-pyretic agent.
