Maximal Suppression

We aimed to assess the parathyroid hormone (PTH) concentration in pregnant women at the beginning of pregnancy (1st trimester) and within days before delivery (3rd trimester) and evaluate its determinants. From September 2014 through December 2015 in a cross-sectional study, 204 women in the 1st trimester of pregnancy and 203 women in the 3rd trimester of pregnancy were recruited. Blood samples were collected to measure PTH and circulating 25-hydroxy-vitamin D (25(OH)D) concentrations. Lifestyle and demographic data were collected using a questionnaire. Serum 25(OH)D and PTH were inversely correlated in both early and late pregnancy. Our analyses suggest that in the 3rd trimester of pregnancy, a 25(OH)D level of 18.9 ng/mL (47.3 nmol/L) could serve as an inflection point for the maximal suppression of PTH. Statistically significant determinants of PTH concentrations in multiple regression were 25(OH)D concentrations, season, multiparity and education of the partner (all p < 0.05) in early pregnancy. In late pregnancy, 25(OH)D concentrations and country of origin were statistically significant determinants of PTH concentrations (all p < 0.05). These factors and their effect on PTH appear to be vastly determined by 25(OH)D; however, they might also affect PTH through other mechanisms besides 25(OH)D.

Vitamin D Levels

Background – Stroke can lead to impaired mobility and disability. There are chances of decreased exposure to sunlight and decreased Vitamin D levels after stroke. This study was done to assess the vitamin D status in stroke survivors and its correlation with duration and ambulatory status of stroke. Methods – This cross sectional study included 100 patients of stroke. Patients were assessed after history and examination for their Serum Vitamin D levels, ambulatory status by Modified Rankin Scale (MRS). MRS grade 1-3 were considered ambulatory and MRS grade 4 and 5 were considered non ambulatory. Statistical analysis was done using chi square test for qualitative variables, unpaired t test for quantitative variables, and pearson correlation. P value < 0.05 was taken significant. Results –72 patients had Vitamin D levels less than 30ng/ml (20.42 ± 5.89 ng/ml). Significant negative correlation was observed between duration of stroke and Serum Vitamin D levels. Out of 41 non ambulatory patients, 38 were Vitamin D deficient (P<0.05). negative Correlation was present in Modified Rankin Scale and Serum Vitamin D levels. Conclusion –Vitamin D Deficiency is present in chronic non ambulatory stroke patients.

Objective: To evaluate the association of the degree of gingival inflammation and 25-hydroxy Vitamin D (25(OH)D) level in postmenopausal women.Methods: A cross-sectional study involved 71 postmenopausal women. Data were obtained using questionnaires, clinical periodontal examinations, and evaluations of blood samples. Serum 25(OH)D concentrations were determined using human 25-dihydroxy Vitamin D ELISA kit.Result: Prevalence of Vitamin D deficiency among postmenopausal women was 74.64%. The papillary bleeding index (PBI) was lower (1.07±0.18) in postmenopausal women with normal serum 25(OH)D levels than that in postmenopausal women with Vitamin D deficiency (1.41±0.1). However, this difference was not statistically significant (p<0.05). This result indicated increasing trends in PBI.Conclusion: There is no association between the degree of gingival inflammation and the 25(OH)D status among postmenopausal women.
