The primary objective of this study was to investigate the etiological causes and the underlying mechanism of post-earthquake dizziness in affected persons. The present study utilized an observational case-control design to recruit 69 participants (33 with self-reported dizziness complaints and 36 healthy persons) who were exposed to the 2023 earthquakes in Türkiye. The participants underwent assessments including the Dizziness Handicap Inventory for measuring dizziness-related disability, stress, and anxiety assessment using various scales, and equilibrium evaluation through the use of videonystagmography, video head impulse test, and vestibular evoked myogenic potential. The 2 groups were compared based on these assessments. The results indicate that the Dizziness Handicap Inventory score was significantly higher in the patient group compared to the control group (P < .001). The mean score of the Peritraumatic Distress Inventory, as well as the mean scores of the Hospital Anxiety and Depression Scale anxiety score and depression score, were found to be significantly higher in the patient group compared to the control group (P=.012, P < .001, and P < .001, respectively). Furthermore, it was observed that the mean vestibulo-ocular reflex gain of the left posterior semicircular canal exhibited a statistically significant decrease in the patient group (P=.02). The observed equilibrium dysfunction experienced by individuals following a significant earthquake is likely attributable to heightened stress and anxiety stemming from multiple sources, including the impact of recurrent vibrations on the inner ear. Therefore, it is essential to establish a holistic healthcare approach that addresses the psychological needs of individuals affected by earthquakes.

Background and Aims: One of the extraosseous effects of vitamin D is that it is a potent modulator of inflammatory processes. Many studies have demonstrated the inverse association between vitamin D and inflammation. Therefore, we hypothesize that vitamin D deficiency may affect the inflammatory markers derived from hemogram parameters [neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR), platelet distribution width (PDW), red blood cell distribution width (RDW)] in healthy children., Methods and Results: We conducted a retrospective study on healthy children. From 2015 to 2020, 16,321 children with simultaneous vitamin D and hemogram measurements were identified from electronic records. Participants were divided into 2 groups according to whether they had vitamin D deficiency or not. The relationship between vitamin D status and the levels of inflammatory markers was analyzed. All inflammatory markers showed statistically significant differences between vitamin D status (p < 0.001 for all). Vitamin D levels were significantly negatively correlated with NLR (r = -0.285), PLR (r = -0.257), PDW (r = -0.181), and positively correlated with LMR (r = 0.218), and RDW (r = 0.057). In logistic regression analysis, age (OR = 1.15, 95% CI: 1.14-1.16), gender (OR = 1.66, 95% CI: 1.54-1.78), LMR (OR = 0.96, 95% CI: 0.95-0.98), PLR (OR = 1.003, 95% CI: 1.001-1.004), and RDW (OR = 1.10, 95%CI: 1.07-1.13) were found to be independent predictors for vitamin D deficiency., Conclusions: Statistically significant differences were detected between vitamin D status and inflammatory parameters. However, the difference between the median values of vitamin D groups was very small and the degree of correlation was very weak. Therefore, the clinical significance of the difference should be questioned., Competing Interests: Declaration of competing interest The authors have no competing interest to disclose., (Copyright © 2022 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

Objective: The aim of this study was to assess the association of vitamin D levels with vitamin B 12 and folate levels in children., Methods: A cross-sectional retrospective study was conducted with 7181 children whose vitamin D, vitamin B 12 , and folate levels were measured simultaneously and analyzed. The mean age of the patients was 10.1 ± 5.2 y (median 10 y). Of the 7181 children in the study, 4047 (56.4%) were girls and 3134 (43.6%) were boys. The children were placed into one of four groups depending on their vitamin D level. Group 1's vitamin D level was <10 ng/mL (n = 2408; 33.5%), group 2: 10 to 19 ng/mL (n = 2504; 34.9%), group 3: 20 to 29 ng/mL (n = 1570; 21.9%), and group 4: ≥30 ng/mL (n = 699; 9.7%). The correlations of vitamin D levels with B 12 and folate were analyzed by Spearman's correlation test., Results: We detected positive, weak but significant correlation between vitamin D and vitamin B12/folate (r = 0.240, P < 0.001 and r = 0.245, P = 0.001, respectively)., Conclusion: The present study reported a positive correlation between vitamin D and vitamin B 12 and folate levels. Regular measurement of these two micronutrient levels in children with vitamin D deficiency is important for public health., (Copyright © 2022 Elsevier Inc. All rights reserved.)
