“…The fact that UV-B is the main factor in the synthesis of vitamin D suggests that this synthesis may differ by seasonal. Dogan and colleagues noted that low vitamin D levels were seen most often in the winter and autumn seasons and least in the summer and spring seasons 6 . The seasonal characteristics of vitamin D levels are associated with geographic hemispheres.…”

Atrial fibrillation (AF) is seen as very common after cardiac surgery. Postoperative AF occurrence increases mortality and morbidity. Deterioration of clinical condition of the patients results prolongation of hospital stay and increases economic burden. Many risk factors that have an impact on the development of postoperative AF are known. Low vitamin D level has been added to these factors in recent years. Blood serum levels of vitamin D is varied seasonally. Therefore, these factors can be expected to have a seasonal effect on development of postoperative AF. The aim of this study is to investigate the presence of annual features of postoperative AF. Method: This study is a retrospective analysis of patients who developed atrial fibrillation after coronary artery bypass graft surgery in the

“…The different laboratory techniques and reference ranges used in the studies also make it difficult to estimate the true prevalence of vitamin D insufficiency [13] . In a study conducted by Doğan et al, [14] the mean vitamin D level was found to be 23.86±10.64 ng/ml in preschool children. When the limit value was taken as 30 ng/ml, vitamin D level was found to be insufficient in 69.9% of these children.…”

Introduction: Vitamin D deficiency and iron deficiency are the most common nutritional pandemic problems worldwide at all levels of society. In some studies, vitamin D has been shown to have an effect on erythropoiesis. The objective of this study was to investigate the relationship between serum vitamin D level, hemogram parameters, and serum iron level in preschool children. Methods: The study group comprised 108 children aged between 2 and 5 years who visited a single pediatric hematology polyclinic between August 2014 and August 2017and whose serum vitamin D level and iron parameters were evaluated. The patients were divided into 3 groups according to the hemoglobin value, serum ferritin level, and transferrin saturation index calculation: iron deficiency, iron deficiency anemia, and a control group. Vitamin D deficiency, insufficiency, and normal categories were also used based on assessment of the serum vitamin D level. Results: There were 41 children in the iron deficiency group, 32 classified as iron deficiency anemia, and 35 age-and sexmated controls. The vitamin D level was statistically significant between the groups (p<0.05). Discussion and Conclusion: According to our findings, vitamin D deficiency and insufficiency were prevalent, especially in children with iron deficiency anemia. It is recommended that the serum vitamin D level of children with iron deficiency anemia should be checked and vitamin D-fortified food consumption should be increased.

“…[1] In recent studies conducted in Turkey, the prevalence of vitamin D deficiency has been reported from 16.5% to 89.6% (Table 4). [6][7][8][9][10][11][12][13][14][15][16][17] Among these studies, the highest rate of vitamin D deficiency was found in the study included pubertal children and adolescents. [11] The lowest deficiency rate was shown in a study conducted on children younger than 10 years old.…”

Aim: Vitamin D deficiency is highly prevalent among children worldwide. This study aims to assess the frequency of vitamin D deficiency in children and how it varies according to gender, age, and season in Istanbul. Material and Method:The study included 3096 children aged 0-18 admitted to the pediatric outpatient clinic in Istanbul. The serum 25 hydroxyvitamin D concentration was analyzed by the High-Performance Liquid Chromatography method using HPLC systems analyzers, and the results were categorized into four groups: deficiency (<20 ng/mL), insufficiency (20-30 ng/mL), sufficiency (30-100 ng/mL), and toxicity (>100 ng/mL). Descriptive methods, Chi-square, Independent Samples T-Test, ANOVA, and correlation test were used in the statistical analysis of the data.Results: Of children, 52% were girls and 48% boys. The mean serum 25 hydroxyvitamin D concentration was 21.8±15.8 ng/mL, and the frequency of vitamin D deficiency was 53.1%. There was a different distribution of vitamin D status between age groups. Vitamin D deficiency was more common in older children. The frequency of vitamin D deficiency was significantly higher in girls than boys (57.6% versus 48.3%). The mean serum 25 hydroxyvitamin D concentration was significantly lower in winter and spring. A moderate negative correlation was found between age and serum 25 hydroxyvitamin D concentration (correlation coefficient:-0.36). Conclusion:This study showed that female sex, older children, and the winter/spring seasons were significantly associated with a higher frequency of vitamin D deficiency and a lower mean serum 25 hydroxyvitamin D concentration.
