Do catecholamines influence myocardial 123I MIBG uptake in neuroblastoma patients?
Routine calculation of H/M ratios in 123I MIBG scintigrams of neuroblastoma patients is not helpful because it will not identify cardiac ventricular dysfunction in this patient category. A low H/M ratio on 123I MIBG scintigraphy is explained by increased cathecholamine levels secreted by neuroblastoma tumours.
The first month of lifestyle treatment is a critical period for helping participants achieve weight loss. Otherwise, individuals who fail to achieve at least 2.5% weight loss may benefit from more intensive rescue efforts or stepped-care interventions.
