        Vitamin D deficiency is a public health emergency amongst indonesian children and adolescents: a systematic review and meta-analysis of prevalence

        Octavius Gilbert Sterling,Shakila Ayesha,Meliani Mariska,Halim Anita 대한소아내분비학회 2023 Apem Vol.28 No.1

        Purpose: This study aimed to describe the prevalence of vitamin D deficiency in Indonesian children and adolescents. Methods: This was a meta-analysis of prevalence using the Hartung-Knapp-Sidik-Jonkman method with a random effects model. A prediction interval was used to estimate true effects. We searched PubMed, MEDLINE, Cochrane Library, Science Direct, Google Scholar, and 3 Indonesian databases (Indonesian Scientific Journal Database, Neliti, and Indonesia One Search). We included cross-sectional or case-control studies that provided data on the prevalence of vitamin D deficiency. We excluded case reports, case series, cohort studies, or studies outside Indonesia. We computed point prevalence by dividing the number of children with hypovitaminosis D by the total number of subjects in that study. This review was registered with PROSPERO (International Prospective Register of Systematic Reviews) (CRD42022329814). Results: Of 1,397 manuscripts identified, 7 were included in this review. A total of 5,870 children were included in this meta-analysis, ranging in age from 6 months to 19 years. The prevalence of hypovitaminosis D in Indonesia was calculated as 33% (95% confidence interval [CI], 9–56) and was higher in females (60% [95% CI, 58–62]) than in males (40% [95% CI, 38–42]). Mean serum vitamin D level was 22.74 ng/mL (95% CI, 16.95–30.51) with a prediction interval of 15.96 ng/mL to 29.52 ng/mL. Conclusion: Vitamin D deficiency is a public health emergency in Indonesia. Strategies to detect and treat vitamin D deficiency in Indonesian children and adolescents should be implemented immediately.

        Antifungal-demelanizing properties and RAW264.7 macrophages stimulation of glucan sulfate from the mycelium of the mushroom Ganoderma lucidum

        Wan Abd Al Qadr Imad Wan-Mohtar,Christina Viegelmann,Anita Klaus,Sarina Abdul Halim Lim 한국식품과학회 2017 Food Science and Biotechnology Vol.26 No.1

        Underutilized mycelium of Ganoderma lucidum BCCM 31549 has been a significant source of a glucan sulfate (GS) possessing therapeutic activities. GS have been evaluated for their antifungaldemelanizing properties and nitrite oxide production from stimulated RAW264.7 macrophages. GS exhibited antifungal activity against Aspergillus niger A60 with a minimum inhibitory concentration of 60 mg/mL and a minimum fungicidal concentration of 100 mg/mL. At 60mg/mL (sublethal) and 30mg/mL (subinhibitory) doses of GS, the mycelium of A. niger A60 was successfully demelanized with a conidiophore head and black pigment reduction. Additionally, GS successfully stimulated RAW264.7 macrophage cells at a concentration of 500 μg/mL to produce 0.45 μM of nitric oxide. The GSstimulated RAW264.7 macrophages were morphologically similar to those treated with lipopolysaccharide. The results highlight a novel bifunctional property of mycelial GS from G. lucidum.
