Article Synopsis
  • The study explores how rumination and mindfulness affect mood and thoughts in women with and without Premenstrual Dysphoric Disorder (PMDD), focusing on different phases of the menstrual cycle.
  • Women with PMDD experienced greater positive mood changes when practicing mindfulness during the late luteal phase, suggesting mindfulness could help manage PMDD symptoms.
  • Both rumination and mindfulness can be used as targets for short-term interventions to improve overall mental health in various populations, regardless of menstrual cycle phase or clinical status.

Article Synopsis
  • PMDD is marked by cyclical mood changes, and this study compared mood and cortisol levels in people with PMDD and healthy controls using ambulatory assessments over a menstrual cycle.
  • Results indicated that those with PMDD experienced worsening mood but no clear cortisol changes, while healthy controls showed decreasing cortisol levels in the late-luteal phase.
  • Findings suggest that while stable cognitive patterns may not help PMDD individuals during premenstrual mood drops, momentary cognitive awareness could offer protective benefits, hinting at potential microinterventions to aid those affected.

Objective: Alcohol use disorder (AUD) constitutes a critical public health issue and has sex-specific characteristics. Initial evidence suggests that progesterone and estradiol might reduce or increase alcohol intake, respectively. However, there is a need for a better understanding of how the menstrual cycle in females and the ratio of progesterone to estradiol in females and males influence alcohol use patterns in individuals with AUD.

Background: Lifetime traumatic events are prevalent in women with Premenstrual Dysphoric Disorder (PMDD) and predict stronger premenstrual symptom intensities. Less is known about the unique effects of childhood adversity on PMDD. This study aims to investigate the menstrual cycle related course of mood, stress appraisal and cortisol activity over time and the effects of childhood adversity - by controlling for recent stressful life events - on the cyclicity of these outcomes.

A cobalt photocatalyst for direct trifluoromethylation of (hetero)arene C(sp)-H bonds is described and shown to operate via visible light activation of a Co-CF intermediate, which functions as a combined chromophore and organometallic reaction center. Chemical oxidations of previously reported (OCO)Co complexes containing a redox-active [OCO] pincer ligand afford a Co-CF complex two oxidation states above Co(II). Computational and spectroscopic studies are consistent with formulation of the product as [(OCO)Co(CF)(THF)(OTf)] () containing an open-shell [OCO] radical ligand bound to a = 0 Co(III) center.
