METHODS: We conducted a meta-analysis to evaluate the association between SCH and depression including 1) the prevalence of depression in SCH (with a sub-analysis of the geriatric cohort), 2) thyroid stimulating hormone (TSH) level among patients with depression and 3) the effect of levothyroxine therapy among patients with SCH and coexistent depression.
RESULTS: In a pooled analysis of 12,315 individuals, those with SCH had higher risk of depression than euthyroid controls (relative risk 2.35, 95% confidence intervals [CI], 1.84 to 3.02; p
METHODS: Based on the initial screening, a total of 100 participants (n = 50 euthymic, n = 50 depressive) underwent 32-channel EEG acquisition. Simple logistic regression and C-statistic were used to explore if EEG power could be used to discriminate between the groups. The strongest EEG predictors of mood using multivariate logistic regression models.
RESULTS: Simple logistic regression analysis with subsequent C-statistics revealed that only high-alpha and beta power originating from the left central cortex (C3) have a reliable discriminative value (ROC curve >0.7 (70%)) for differentiating the depressive group from the euthymic group. Multivariate regression analysis showed that the single most significant predictor of group (depressive vs. euthymic) is the high-alpha power over C3 (p = 0.03).
CONCLUSION: The present findings suggest that EEG is a useful tool in the identification of neurophysiological correlates of depressive symptoms in young adults with no previous psychiatric history.
SIGNIFICANCE: Our results could guide future studies investigating the early neurophysiological changes and surrogate outcomes in depression.
METHODS: This is a retrospective comparative cohort study design. Two hundred and fifty Malaysian women were part of a previous study examining the prevalence of PND in a multiracial country and the effects of postnatal rituals. All women were at least 6 weeks post-partum when asked to complete the Edinburgh Postnatal Depression Scale (EPDS). Sociodemographic and birth data were obtained.
RESULTS: Data collected were divided into two groups: 55 emergency delivery and 191 non-emergency delivery. There were four missing data. There was no significant difference in the mean age, parity, gestational period, baby birthweight, 5 min baby Apgar score and EPDS scores of the two groups. However, the analysis of PND indicated that women with emergency delivery had a relative risk of 1.81 compared with women with non-emergency delivery. The comparison of the two groups using chi2 indicated a significant (chi2 = 3.94, d.f. = 1, P = 0.04) increase in the presence of PND in the emergency delivery.
CONCLUSION: When compared with women having non-emergency delivery, women having emergency delivery had about twice the risk of developing PND. Special attention to this group appears warranted.
