Maintenance of certification in psychiatry.

The American Board of Medical Specialties (ABMS) developed 6 core competencies for physicians of all specialties and a maintenance of certification (MOC) program for board-certified physicians. The MOC program incorporates the 6 competencies into 4 component areas: professional standing, self-assessment and lifelong learning, cognitive expertise, and performance in practice. These 4 components are designed to promote a cycle of lifelong learning, self-assessment and peer review, and incorporation of best practices in order to improve the quality of health care in clinical practice.

Relationship between Resident-In-Training Examination in psychiatry and subsequent certification examination performances.

Objective: This study analyzed the relationship between performance on The American College of Psychiatrists' Psychiatry Resident-In-Training Examination (PRITE) and the ABPN Part 1 examination.

Methods: Pearson correlation coefficients were used to examine the relationship between performance on the 2002 PRITE and the 2003 Part 1 examination for 297 examinees.

Results: The correlation between the PRITE global psychiatry and the Part 1 psychiatry scores was 0.

Association of a critical CSF tryptophan threshold level with depressive relapse.

This work studies association between relapse during acute tryptophan depletion (ATD) and CSF level of tryptophan (TRP) in remitted depressives treated with sertraline or bupropion. Eight medication-responding depressives ingested an ATD amino acid mixture during 48-h continuous CSF sampling before and after treatment. Mood rating scores were compared with nadir levels of TRP in CSF.

Serial cerebrospinal fluid tryptophan and 5-hydroxy indoleacetic acid concentrations in healthy human subjects.

The role of the serotonergic system in the pathogenesis of behavioral disorders such as depression, alcoholism, obsessive-compulsive disorder, and violence is not completely understood. Measurement of the concentration of neurotransmitters and their metabolites in cerebrospinal fluid (CSF) is considered among the most valid, albeit indirect, methods of assessing central nervous system function in man. However, most studies in humans have measured lumbar CSF concentrations only at single time points, thus not taking into account rhythmic or episodic variations in levels of neurotransmitters, precursors, or metabolites.
