- Seasonality in Major Depressive Disorder: Effect of Sex and Ageby Matthäus Fellinger on October 2, 2021
CONCLUSIONS: The current study indicates a seasonal variation in MDD symptoms that may go beyond seasonal affective disorder. Knowledge about the predictability of depressive symptoms in patients should encourage preventive strategies.
- Body mass index and atypical balance as predictors of winter depression remission in cognitive-behavioral therapy and light therapyby Praise Iyiewuare on September 28, 2021
CONCLUSIONS: BMI and atypical balance prescriptively predicted higher likelihood of depression remission two winters following CBT-SAD but not LT. This work informs clinical decision-making and precision medicine efforts.
- The Timing of Clinical Effects of Bupropion Misuse Via Insufflation Reported to a Regional Poison Centerby Daniel J McCabe on September 20, 2021
CONCLUSIONS: This report describes the clinical effects reported, and the timing of these effects, after insufflation of bupropion.
- Variations in seasonal solar insolation are associated with a history of suicide attempts in bipolar I disorderby Michael Bauer on September 1, 2021
CONCLUSION: A large change in solar insolation, both between winter and summer and between the minimum and maximum monthly values, may increase the risk of suicide attempts in bipolar I disorder. With frequent circadian rhythm dysfunction and suicidal behavior in bipolar disorder, greater understanding of the optimal roles of daylight and electric lighting in circadian entrainment is needed.
