Summary: This study evaluated the satisfaction of women who had recently used a monthly contraceptive ring or contraceptive pills with a segesterone acetate and ethinyl estradiol contraceptive vaginal system. The results showed high satisfaction with the vaginal system, and most women liked it as much or better than any previous contraceptive method. The ease of use and one-year duration were the most liked features, while ring insertion and feeling it coming out were the most disliked features. The majority of participants had no concerns about using the system for a year and had recommended it to others.

Summary: The theory of seizures beget seizures suggests that seizure activity can contribute to the progression of epilepsy. However, existing data and observations both support and oppose this theory. While recurrent seizures can cause negative changes in brain structure and function, other factors may also play a role in epilepsy progression.

Summary: Post-traumatic epilepsy (PTE) is a chronic seizure condition that occurs after traumatic brain injury (TBI). Currently, there is a lack of approved treatments to prevent PTE, and many cases are unresponsive to antiseizure medications. This study provides a critical review of the current state of PTE research, focusing on experimental models, molecular mechanisms, biomarkers, and potential interventions. There is new optimism in finding drug therapies for preventing PTE in high-risk populations, especially in military personnel.

Summary: This article discusses the critical role of neurosteroids in postpartum depression (PPD) and introduces the breakthrough antidepressant brexanolone as a first-in-class neurosteroid therapy. PPD, a neuroendocrine disorder affecting 20% of mothers, is characterized by symptoms such as persistent sadness, fatigue, dysphoria, and disruptions in cognition, emotion, appetite, and sleep. The main pathology behind PPD is the reduction of neurosteroids after childbirth, known as neurosteroid withdrawal. Brexanolone, a progesterone-derived allopregnanolone, rapidly alleviates anxiety and mood deficits by activating GABA-A receptors, making it a transformative treatment for PPD with significant advantages over traditional antidepressants.
