Objective. In this pilot study, we aimed to analyze the blood irisin levels in relation to glucose and mineral metabolism assays in menopausal women with non-diabetic altered glucose regulation: impaired fasting glucose (IFG) or impaired glucose tolerance (IGT). Methods. This was a prospective, transversal, non-interventional, bi-centric (bi-country) study, between December 2024 and October 2025. Results. The patients (N=47) with IGT (N=21) or IFG (N=26) had a similar age (63±9.24 versus 63.46±8.16years, p=0.856), menopause duration (14.05±9.37 versus 16.76±8.07years, p=0.297), and body mass index with mean values within the obesity range (34.84±5.07 versus 31.34±6.46kg/sqm, p=0.765). Average 25-hydroxyvitamin D showed an insufficiency (28.62±8.09 versus 28.06± 6.99ng/mL). The IGT versus IFG group were found with statistically significantly higher 1-hour glycaemia in the oral glucose tolerance test (207.04±34.72 versus 179.40±33.91mg/dL, p=0.009), 2-hour insulin (101.44±67.26 versus 48.97±34.35 µUI/mL, p=001), fasting insulin (13.00±7.38 versus 8.36±3.96µUI/mL, p=0.008); HOMA-IR (3.53±2.32 versus 2.27±1.17; p=0.21) with mean levels sustaining insulin resistance. Conclusion. Circulating irisin was marginally elevated in the IGT versus the IFG group and positively correlated with body mass index in both. We found no correlation with the glucose profile, but with selective mineral metabolism assays. This pilot study requires an expansion of the sample size to pinpoint the potential practical utility of irisin as a biomarker.
Since vitamin D is synthesized from cholesterol, it is claimed to be associated with insulin resistance, suggesting that there may be an association between vitamin D glucose and lipids. For this reason, we aimed to investigate a relationship between vitamin D and biochemical parameters, including glucose and lipids. This cross-sectional study included 198 patients .admitted to the family medicine outpatient clinic between June and December 2016. There was no significant correlation between vitamin D and serum glucose, total cholesterol, triglyceride, HDL cholesterol, LDL cholesterol, calcium, magnesium, sodium, TSH, and body mass index values in both men and women. There was a correlation between vitamin D and total cholesterol and LDL cholesterol levels in the younger subjects below 41 years (p=0.002). Regression analysis with other variables showed no statistical significance between vitamin D levels on LDL-C levels (P=0.309). Despite previous studies, our study did not confirm the effects of vitamin D on serum glucose, lipid, calcium, and other biochemical parameters. However, these results suggest that the standard up-to-date literature showing the relationship between vitamin D and various metabolic and hormonal disorders may need to be confirmed by new large-scale studies.
There are conflicting data on the effects of magnesium on hypertension in the literature. Therefore we aim this study to investigate whether there is a relationship between serum magnesium levels and hypertension in newly diagnosed. This is a case-control study. The patients were selected from the records of patients who applied to the family medicine outpatient clinic between June 2016 and May 2017. A total of 276 patients, 68 patients with newly diagnosed hypertension in the case group and 208 patients without any disease in the control group were included in the study. Binary logistic regression analysis was performed between the case and control groups. The odds ratio for magnesium was 0.1 (0.012-0.810). When the value of the magnesium variable increases by 1mg/dl, the risk of hypertension decreases by 90%. However, in the presence of magnesium as an independent variable, the predictability rate of our model was expected to increase but decreased. The odds ratio for age was
