- Vitamin A deficiency is a significant health issue among preschool children in Northeast Brazil, particularly in Teresina, Piauí, with a prevalence of 15.4%.
- The study analyzed 631 children aged 36 to 83 months, measuring serum retinol levels and evaluating factors such as demographics and socioeconomic status.
- Factors like age, income, maternal schooling, and vitamin A supplementation showed positive correlations with higher retinol levels, indicating the need for effective public health strategies to address this deficiency in the region.
Article Abstract
Vitamin A deficiency is a public health problem in the Northeast of Brazil. This study aimed to determine the prevalence of vitamin A deficiency and associated factors among preschool children in Teresina, Piauí, Brazil. We studied the serum retinol levels and socioeconomic and demographic characteristics of 631 children from 36 to 83 months of age. The statistical association between each of the above characteristics and serum retinol levels was investigated by univariate and multivariate linear regression analysis. Mean serum retinol was 1.21 mmol/L (95%CI: 1.17-1.25 micromol/L) and was independent of gender (p = 0.259). Prevalence of vitamin A deficiency (retinol < 0.69 micromol/L) was 15.4% (95%CI: 12.7-18.4), with a tendency to decrease with age. Acceptable but not adequate retinol levels (0.70 to 1.04 micromol/L) were observed in 29% of children (95%CI: 25.2-32.4). There were positive associations between retinol levels and age, income, vitamin A supplementation, and maternal schooling. Vitamin A deficiency appeared as a moderately serious public health problem, emphasizing the importance of strategies to combat this problem in the region.

Vitamin B12 deficiency is a potentially severe condition with clinical manifestations ranging from nonspecific symptoms, such as asthenia and glossitis, to severe hematological problems, including pancytopenia and megaloblastic anemia. One of the rare phenomena associated with this condition is pseudo-thrombotic microangiopathy (pseudo-TMA), which can mimic diseases such as thrombotic thrombocytopenic purpura (TTP), leading to possible misdiagnosis and inappropriate treatment. In this article, we present the case of a 62-year-old man with a history of intravenous drug use, untreated hepatitis C, smoking, and alcoholism.

Background: Biological evidence has revealed antitumor effect of vitamin D, but whether it could predict the response to neoadjuvant chemotherapy (NAC) in breast cancer (BC) patients remains inconclusive. The aim was to investigate the association between pretreatment vitamin D level and response to NAC and subsequent survival outcomes in BC patients.
Materials And Methods: The authors systematically searched the Medline, Embase, Cochrane Library, and Web of Science databases and clinical trial registries to identify relevant articles from inception to 8 October 2024.

Background: Socioeconomic inequality in nutritional status as one of the main social determinants of health can lead to inequality in health outcomes. In the present study, the socioeconomic inequality in the burden of nutritional deficiencies among the countries of the world using Global Burden of Disease (GBD) data was investigated.
Methods: Burden data of nutritional deficiencies and its subsets including protein-energy malnutrition, iodine deficiency, vitamin A deficiency, and dietary iron deficiency form GBD study and Human Development Index (HDI), a proxy for the socio-economic status of countries, from united nations database were collected.

Background: 25-hydroxyvitamin D [25(OH)D] concentrations and physical activity (PA) are linked and both are associated with changes in mortality. We examined the association of 25(OH)D and PA with all-cause or cause-specific mortality risk in stroke survivors.
Methods: The analysis included 677 stroke survivors from National Health and Nutrition Examination Survey (NHANES) 2007-2008 to 2017-2018.
