Risk factors for cardiac dysfunction in children on treatment for cancer at Kenyatta National Hospital, Nairobi
Objective: To determine the point prevalence of abnormal cardiac function and to assess the risk factors for cardiac dysfunction in paediatric oncology patients on treatment at Kenyatta National Hospital. Design: Descriptive cross-sectional study with a nested case control. Setting: Kenyatta National Hospital between February and April 2006. Main outcome measures: Left ventricular dysfunction if ejection fraction (EF) 29%. Results: One hundred and eleven patients were enrolled of whom 32 had abnormal cardiac function and were classified as cases while 79 had normal cardiac function. About a third, point prevalence 29% (95% CI 21.2-37.9), had cardiac dysfunction. Cumulative anthracycline dose was a risk factor for cardiac dysfunction in this population. Above 200mg/m2 the attributable risk percentage of cardiac dysfunction was 77%. Conclusions: Serial echocardiography should be performed to identify patients at risk. Alternative treatment protocols should be used when the cumulative anthracycline dose exceeds 200mg/m2 due to the high attributable risk. Studies to further assess the other associated risk factors and long term effects of anthracycline are recommended
Impacts of Patient Characteristics on the Effectiveness of Landiolol in AF/AFL Patients Complicated with LV Dysfunction: Subgroup Analysis of the J-Land Study
Experimental Study on Temperature Coefficient of Reactivity in Light-Water-Moderated and Heavy-Water-Reflected Cylindrical Core Loaded with Highly-Enriched-Uranium or Medium-Enriched-Uranium Fuel
Replication timing: histone genes replicate during early S phase in cleavage-stage embryos of sea urchin.
Newly synthesized DNA was separated from the bulk of the DNA by pulse-labeling with BUdR and centrifugation in an alkaline CsCl buoyant density gradient. The content of histone gene in the newly synthesized DNA was determined by DNA dot hybridization. The gene contents in DNA replicated during the early half of S phase and during the whole S phase were compared. Results showed that histone genes were replicated during the first half of the S phase in embryos in the early cleavage stage
RISK FACTORS FOR CARDIAC DYSFUNCTION IN CHILDREN ON TREATMENT FOR CANCER AT KENYATTA NATIONAL HOSPITAL, NAIROBI
Objective: To determine the point prevalence of abnormal cardiac function and to assessthe risk factors for cardiac dysfunction in paediatric oncology patients on treatmentat Kenyatta National Hospital.Design: Descriptive cross-sectional study with a nested case control.Setting: Kenyatta National Hospital between February and April 2006.Main outcome measures: Left ventricular dysfunction if ejection fraction (EF) <55% orfractional shortening (FS) <29% defined cases. Controls had EF >55% or FS >29%.Results: One hundred and eleven patients were enrolled of whom 32 had abnormalcardiac function and were classified as cases while 79 had normal cardiac function. Abouta third, point prevalence 29% (95% CI 21.2-37.9), had cardiac dysfunction. Cumulativeanthracycline dose was a risk factor for cardiac dysfunction in this population.
