Researchers have discovered biomarkers that can detect Peripartum Cardiomyopathy (PPCM), a life-threatening disorder in pregnant women, allowing for early treatment and a significant reduction in mortality. The test aims to differentiate PPCM from normal pregnancy symptoms, enabling timely intervention.
Participants in a 12-week pilot program received monthly naltrexone injections and set their own treatment goals, resulting in decreases in alcohol craving (33%), consumption (25-34%), and problems associated with alcohol use (60%). The counseling approach was non-judgmental and focused on participants' individual goals.
Deep brain electrode implantation may be a suitable alternative to the traditional WADA test for identifying speech dominance, especially in patients with uncertain side of speech dominance or small children who cannot cooperate. The 'Electric WADA' procedure was successful in four patients without adverse events.
