Prompt and effective treatment of maternal depression during pregnancy is important as it is an independent predictor of negative maternal and fetal outcomes. Yoga is an increasingly popular non-pharmacological modality. This study thus aimed to undertake a meta-analysis of the efficacy of yoga-based interventions for maternal depression during pregnancy. A total of 8 clinical studies were systematically reviewed, and 6 studies with a total of 405 pregnant mothers were included in the final meta-analysis. Applying per-protocol analysis and a random-effects model, the pooled standardized mean difference (SMD) from baseline depressive score was -0.452 (95% CI: -0.816 to -0.880, P = 0.015), supporting a statistically significant beneficial effect of yoga-based interventions on mood. Overall, yoga-based interventions are a promising non-pharmacological option, however, most trials examined were preliminary, recruited only participants with mild depression, did not blind study participants and had relatively small sample sizes. Larger randomized, controlled trials should be encouraged.

03:12Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
