A Brief Overview Of Adolescent Developmental Problems In Hong Kong, Daniel T. L. Shek, Hing Keung Ma, Rachel C. F. Sun

Pediatrics Faculty Publications

Several adolescent developmental problems in Hong Kong are briefly reviewed in this paper. First, rising adolescent substance abuse trends are described. Second, Internet use problems and Internet addiction among young people are examined. Third, worrying trends in adolescent sexuality are identified. Fourth, phenomena on bullying among young people are reviewed. Finally, phenomena related to adolescent materialistic orientation are focused upon. With reference to these adolescent developmental problems, possible solutions are briefly discussed particularly with reference to the ecological perspective. It is argued that the related scientific literature provides useful pointers for designing the curriculum in the extension phase of the …

Cardiovascular Magnetic Resonance Myocardial Feature Tracking Detects Quantitative Wall Motion During Dobutamine Stress., Andreas Schuster, Shelby Kutty, Asif Padiyath, Victoria Parish, Paul Gribben, David A. Danford, Marcus R. Makowski, Boris Bigalke, Philipp Beerbaum, Eike Nagel

BACKGROUND: Dobutamine stress cardiovascular magnetic resonance (DS-CMR) is an established tool to assess hibernating myocardium and ischemia. Analysis is typically based on visual assessment with considerable operator dependency. CMR myocardial feature tracking (CMR-FT) is a recently introduced technique for tissue voxel motion tracking on standard steady-state free precession (SSFP) images to derive circumferential and radial myocardial mechanics.We sought to determine the feasibility and reproducibility of CMR-FT for quantitative wall motion assessment during intermediate dose DS-CMR.

METHODS: 10 healthy subjects were studied at 1.5 Tesla. Myocardial strain parameters were derived from SSFP cine images using dedicated CMR-FT software (Diogenes MRI prototype; …
