Vitamin A

A meta-analyze on vitamin A (VA) and anemia surveys in the year 1995 and 2000. The results showed that anemis is reducing during the recent years, particularly more in pregnancy women, and less in young infants. However anemis is still a public health significant problem (PHS). Clinical VA lesions are continuously lower than PHS. While the sub-clinical VA deficiency is still a PHS, of which majority is in mild and moderate levels. It was recognized that the problem is more severe in young infant < 6 months. Low VA content in breast-milk is more than 50% among lactating women. The recommendations, such as social marketing on the using iron tablet, iron fortification into several foods have been developed for control of anemia; VA capsule supplementation of 50,000 IU to the infant < 6 months combined with immunization of PDT on 6, 10, 14 weeks; Increasing doses of VA for women after delivery. Weekly supplementation of iron combined with low dose VA to pregnance women

This study was conducted on biscuit had been fortified with vitamin A and iron that was produced at the H¶i Hµ factory during Sep - Oct 1997. Fortified biscuit was analyzed for sensory aspects (color, odor, taste), chemical composition (energy value, protein, fat, carbohydrate, iron and vitamin A contents), level of micro-organism and mould at time of production and after 4 months of preservation. The results showed that 100 g of fortified biscuit contained 6.9 g of protein, 22.4g of fat and 51.2g of carbohydrate, given 434 kcal, 3600 UI retinol and 17.17 mg iron. After 4 months, it remained to contain 3100 UI retinol and 17 mg iron per 100g. The microorganism and mould indices complied with standards. The product had good color, odor and taste and caused no digestive problem after eating. This biscuit product is inexpensive. With only 600 VND, the children will be able receive 5.1mg of elemental iron, 356mcg of vitamin A, 2.1g of protein, 6.7g of fat and 130kcal. (Auth)

Vitamin A is an important micronutrient for human health. It has a good effect on many diseases such as diarrhea, malnutrition, HIV/AIDS, malaria... Vitamin A and/or -carotene as well as other micronutrients contribute to many physiological and pathological process of the body. In Vietnam, the rate of Vitamin A deficiency remains high. Therefore, it should have a strategy for mass complement of vitamin A, high dose and periodical complement of vitamin A for children, vitamin A containing diets and health education.

Vitamin A (VA) status was assessed in young children and lactating women in Red River Delta area. Results showed that pre-clinical VA deficiency rate, expressed by low level of retinol in serum and in milk is very frequent (10.8% in children, and 56.3% in lactating women) and was at, severity degree according to the IVACG/WHO classification. Low levels of VA and lipid in the dietary intake are a major cause of VA deficiency in the rural community in Vietnam

Objectives: This study aimed to compare the severity of COVID-19, inflammatory parameters and clinical outcomes among patients with normal and subnormal levels of Vitamin D. Methodology: This is a retrospective cohort study of 135 patients admitted in a tertiary hospital for COVID-19. Patients were grouped according to their Vitamin D level. Primary outcome measure was the composite of all-cause mortality and morbidity. Other outcome measures determined were the comparison among the groups on the severity of COVID-19 infection, changes in inflammatory parameters, length of hospital stay and duration of respiratory support. Results: There was a significant trend of higher ICU admission (p=0.024), mortality (p=0.006) and poor clinical outcome (p=0.009) among the Vitamin D deficient group. No significant difference was found for most of the inflammatory parameters, duration of hospital stay and respiratory support. Overall, patients with deficient, but not insufficient Vitamin D level had 6 times higher odds of composite poor outcome than those with normal Vitamin D (crude OR=5.18, p=0.003; adjusted OR=6.3, p=0.043). Conclusion The inverse relationship between Vitamin D level and poor composite outcome observed in our study suggests that low Vitamin D may be a risk factor for poor prognosis among patients admitted for COVID-19.
