Diurnal and circadian variation of sleep and alertness in men vs. naturally cycling women.

This study quantifies sex differences in the diurnal and circadian variation of sleep and waking while controlling for menstrual cycle phase and hormonal contraceptive use. We compared the diurnal and circadian variation of sleep and alertness of 8 women studied during two phases of the menstrual cycle and 3 women studied during their midfollicular phase with that of 15 men. Participants underwent an ultradian sleep-wake cycle (USW) procedure consisting of 36 cycles of 60-min wake episodes alternating with 60-min nap opportunities.

Brief motivational interviewing for DWI recidivists who abuse alcohol and are not participating in DWI intervention: a randomized controlled trial.

Background: Driving while impaired (DWI) recidivists with unresolved alcohol use problems pose an ongoing risk for traffic safety. Following conviction, many do not participate in mandated alcohol evaluation and intervention programs, or continue to drink problematically after being relicensed. This study investigated if, in DWI recidivists with alcohol problems and not currently involved in DWI intervention, Brief Motivational Interviewing (BMI) produced greater reductions in risky drinking at 6- and 12-month follow-up compared to an information-advice control condition.

The 5HTTLPR polymorphism, psychopathologic symptoms, and platelet [3H-] paroxetine binding in bulimic syndromes.

Background: A short (s) allele in the promoter region of the 5-hydroxytryptamine (5-HT) transporter gene (5HTTLPR) has been associated with low transcription of the 5-HT transporter protein, and with clinical manifestations including impulsivity, affective disorder, and bulimia nervosa.

Methods: We studied implications of the 5HTTLPR s allele for eating symptoms, psychopathologic traits, and platelet [3H-] paroxetine binding in 59 women with bulimia spectrum syndromes.

Results: Compared with those without it, carriers of the s allele of 5HTTLPR showed significantly more affective instability, behavioral impulsivity, interpersonal insecurity, comorbid borderline personality disorder (BPD), and lower density (Bmax) of paroxetine-binding sites.
