ABSTRACT
Background: A prospective cohort study to correlate perceived sleep disturbances in depressed patients with objective changes in sleep architecture using polysomnography (PSG) before and after antidepressant therapy.Methods: Patients were recruited into the study after applying strict inclusion and exclusion criterion to rule out other comorbidities which could influence sleep. A diagnosis of Depressive episode was made based on ICD-10 DCR. Psychometry, in the form of Beck Depressive inventory (BDI) and HAMD (Hamilton depression rating scale) insomnia subscale was applied on Day 1 of admission. Patients were subjected to sleep study on Day 03 of admission with Polysomnography. Patients were started on antidepressant treatment post Polysomnography. An adequate trial of antidepressants for 08 weeks was administered and BDI score ≤09 was taken as remission. Polysomnography was repeated post remission. Statistical analysis was performed using Kruskal Wallis test and Pearson correlation coefficient.Results: The results showed positive (improvement) polysomnographic findings in terms of total sleep time, sleep efficiency, wake after sleep onset, percentage wake time and these findings were statistically significant. HAM-D Insomnia subscale was found to correlate with total sleep time, sleep efficiency, wake after sleep onset, total wake time and N2 Stage percentage.Conclusions: Antidepressant treatment effectively improves sleep architecture in Depressive disorder and HAM-D Insomnia subscale correlates with objective findings of total sleep time, sleep efficiency, wake after sleep onset, total wake time and duration of N2 stage of NREM.
ABSTRACT
Background: An observational study was undertaken to study the relationship between maternal serum vitamin D levels during peripartum period and neonatal birth weight.Methods: This study was done on 569 patients to study the relationship between maternal serum vitamin D levels during peripartum period and neonatal birth weight. The data included was maternal serum samples (taken during peri-partum period) and neonatal birth weight. The primary objective of this project was to assess the vitamin D levels in maternal serum and to study its relationship, if any, with birth weight in the neonates.Results: A total of 569 samples of maternal serum were analyzed for serum 25(OH)D levels out of which 457(80%) mothers were found to have sufficient, 101(18%) insufficient and 11(2%) deficient Vitamin D levels as per US Endocrinological society guidelines. Out of total 569 newborns, 104 (18.27%) were low birth weight (LBW) and 465 (81.27%) were normal birth weight (NBW). Out of total LBW (104), 19(18.27%) were born to vitamin D deficient (VDD) mothers and 85 (81.72%) were born to vitamin D sufficient (VDS) mothers. Out of total NBW(465), 86(18.45%) were born to VDD mothers and 379 (81.17%) were born to VDS mothers. These results were not statistically significant (p=0.76456749).Conclusions: Maternal 25(OH)-vitamin D status during late pregnancy did not have any statistically significant effect on the neonatal birth weight.
