CANCER SURGERY MORTALITY AND HOSPITAL VOLUME

In a retrospective analysis of data from the linked Surveillance, Epidemiology, and End Results (SEER)–Medicare database, Begg and colleaguesArticle found that the 30-day mortality after complex surgical oncology procedures was significantly lower at hospitals with high volumes of these cases. In a related editorial, Hillner and SmithArticle suggest that high-risk oncologic surgery should be concentrated in designated high-volume centers to improve patient outcomes.

SERTRALINE IMPROVES SYMPTOMS OF OCD IN CHILDREN

Few trials of medications for the treatment of obsessive-compulsive disorder (OCD) have been conducted in children and adolescents, even though this population constitutes about half of all patients with OCD. In this 12-week multicenter trial, March and colleaguesArticle found that children and adolescents treated with sertraline had significant symptomatic improvement compared with those who received placebo. In a related editorial, RapoportArticle discusses the importance of further research on the neurobiology and pharmacotherapy of OCD in children.

COST-EFFECTIVENESS OF SCREENING FOR TYPE 2 DIABETES

Type 2 diabetes is often undetected until after the development of microvascular complications. The CDC Diabetes Cost-Effectiveness Study Group developed a computer simulation model to estimate the cost-effectiveness of early diagnosis and treatment of type 2 diabetes. They found that a 1-time population-based screening program of individuals aged 25 years and older would be most cost-effective in younger individuals and those at high risk of developing major complications.

DIALYSIS DOSE INADEQUATE PREDICTOR OF SURVIVAL

In a retrospective analysis of data from more than 18,000 patients with end-stage renal disease receiving hemodialysis, Owen and colleagues found that the association between the urea reduction ratio (the usual measure of dialysis dose) and survival varied according to race and sex subgroups. In white women, mortality risk increased steeply as the urea reduction ratio decreased below 60%, but this association was weak among black men.

CARDIAC ARRHYTHMIAS WITH ERYTHROMYCIN

The risk of torsades de pointes arrhythmias with antiarrhythmic drugs is greater in women than men, but this association has not been studied in other drug classes. In this 2-part study, Drici and colleagues found that voluntary reports of cardiac arrhythmias associated with erythromycin submitted to the FDA MEDWATCH Spontaneous Reporting System were more frequent for women than men. In studies of isolated rabbit hearts perfused with erythromycin, QT-prolongation was significantly greater in female than in male rabbit hearts.

EQUIVOCAL EFFICACY OF TACRINE IN ALZHEIMER DISEASE

In a meta-analysis of data from 1984 patients in 12 trials of tacrine for the treatment of Alzheimer disease, Qizilbash and colleagues found that patients treated with tacrine had a slower rate of cognitive decline at 12 weeks than patients who received placebo. Improvements in behavioral disturbance in patients treated with tacrine were of uncertain clinical significance and there were no significant effects on functional autonomy.
