Background: Previous studies have reported a high frequency of vitamin D deficiency (VDD) among different age groups in Iran.
Aims: In this study, the current coverage, status of vitamin D supplement taking, and program efficacy have been evaluated by the Office of Nutrition Department Society in Iran since 2014.
Methods: This study was conducted in collaboration with the International UNESCO center for Health-Related Basic Sciences and Human Nutrition and the Office of Nutrition Department Society. Sixty three medical universities were included in the current study to calculate the availability, accessibility and acceptability coverages. Furthermore, 3 medical universities including Mashhad (MUMS), Qom (QUMS) and Zahedan (ZAUMS) University of Medical Sciences were selected based on the results of the National Integrated Micronutrient Survey 2012 (NIMS-II study), in order to assess the status of vitamin D supplement intake in all age ranges.
Results: Quantitative analysis showed that availability coverage was 74.96% and 77.56% and accessibility was 80.70% and 83.26% in elderly and middle-aged subjects, respectively in 2018. The acceptability was approximately 43.7% and 43.9% among elderly and middle-aged participants, respectively. The availability and acceptability coverage was 80.99% and 85.0% among students in high schools. The mean vitamin D supplement uptake frequency was 27.0% (n = 387); 20.7% and 29.2% in rural and urban area, respectively (P = 0.001). The results showed that there was no significant difference in serum vitamin D levels between urban (20.41 ± 6.43 ng/ml) and rural areas, (P = 0.887). There was no significant difference in the serum vitamin D concentrations between men and women (P = 0.461).
Conclusions: The frequency of taking vitamin D supplements was 27.0% in Iran in 2018. The frequency of taking of vitamin D supplements among vitamin D deficient group (serum vitamin D levels <19.99 ng/ml) was 43.6%. Lack of knowledge was the most important reason for not taking vitamin D supplement. Moreover, the serum vitamin D levels have increased in subjects aged 18-30 years old after the implementation of the vitamin D supplementary program.

Animal-based foods such as meat, dairy, and eggs contain abundant essential proteins, vitamins, and minerals that are crucial for human nutrition. Therefore, there is a worldwide growing demand for animal-based products. Since animal-based foods are vital resources of nutrients, it is essential to ensure their microbial safety which may not be ensured by traditional food preservation methods.

Background: Several studies have assessed the epidemiology of sarcopenia in Iran with conflicting results, but comprehensive information has remained limited. Therefore, we aimed to perform a systematic review and meta-analysis of the prevalence of sarcopenia and its associated factors among Iranian population.
Methods: We searched in Embase, PubMed, Scopus, and Google Scholar, as well as Persian databases including the Scientific Information Database and Magiran, from inception to 31 May 2024.

In order to improve the drying quality of winter jujube slices and find the best drying process parameters, RF + HA (radio frequency combined hot air) drying technology was used in this study to study the effects of plate spacing, RF application time, and RF interval time on the quality of winter jujube slices. Vitamin C () content, red and green value (), and drying rate () were used as quality indexes, and the changing trend of texture properties was analyzed. According to the conclusion of the single-factor experiment, the orthogonal experiment is carried out, and the parameters of each factor in the orthogonal experiment are optimized by the comprehensive balance method and matrix analysis method.

Abstract: Recent clinical trials on slowing dementia progression have led to renewed focus on finding safer, more effective treatments. One approach to identify plausible candidates is to assess whether existing medications for other conditions may affect dementia risk. We conducted a systematic review to identify studies adopting a data-driven approach to investigate the association between a wide range of prescribed medications and dementia risk.

Background: Vitamin K antagonists (VKA) continue to be the principal anticoagulants for both the treatment and prevention of venous thromboembolism. The use of VKA often requires regular monitoring to avoid over-anticoagulation and prevent thromboembolic complications. The aim was to determine the indication for VKA use and factors associated with suboptimal anticoagulation control among patients in northern Tanzania.
