How should the clinician evaluate and manage the cardiovascular complications of anorexia nervosa?

Five to twenty percent of patients with anorexia nervosa die from their illness. One half of those patients die of medical complications (Steinhavsen, 2002). Malnutrition, dehydration, and electrolyte abnormalities may precipitate death by inducing heart failure or fatal arrhythmias.

Parent reasons for nonreturn to a pediatric weight management program.

To identify parent reasons for lack of return to a weight management program, a questionnaire was sent to 85 families who attended two or fewer visits; 43 families completed the questionnaire. A total of 37% reported that the program was not what they were looking for. Specifically, they were dissatisfied with the staff or treatment focus.

Activation of AP-1 through reactive oxygen species by angiotensin II in rat cardiomyocytes.

Cardiovascular pathogenesis induced by angiotensin II (Ang-II) is a complex process often connected to oxidative stress. In the present study we show that, 4 h after addition, Ang-II induces a four- to fivefold increase in AP-1 activity in cultured neonatal rat cardiomyocytes and that the intracellular level of reactive oxygen species (ROS) correlates with the extent of AP-1 binding activity. Ang-II stimulated ROS generation in rat cardiomyocytes in a dose- and time-dependent manner.

Adolescents' compliance with return visits for depot medroxyprogesterone initiation.

Study Objectives: To determine if and when female adolescents choosing depot medroxyprogesterone would return for a second visit for initiation of the method.

Design/setting: Retrospective chart review at an adolescent clinic in an urban health department in St. Louis, MO.

GABAA receptor-expressing astrocytes in the supraoptic nucleus lack glutamate uptake and receptor currents.

An important function of astrocytes is the clearance of excess extracellular glutamate via specific carriers whose expression has become an astrocytic marker. In the present study, we found that a large population of astrocytes in the supraoptic nucleus (SON) of the rat hypothalamus lacks glutamate uptake currents and receptor responses but expresses GABAA receptors. Patch clamp recordings in acute hypothalamic slices that included the SON showed typical astrocytic membrane currents and demonstrated that GABA, via GABAA receptor activation, triggered a conductance increase with the reversal potential close to the Cl- equilibrium potential and a decrease in resting K+ conductance.
