Intravenous amiodarone is safe and effective in most young patients with critical tachyarrhythmia. Intravenous amiodarone can be lifesaving, particularly for postoperative junctional ectopic tachycardia, when standard therapy is ineffective.

In the midst of an information age and a global economy, people around the world continue to face significant inequities at school and in the workforce. Career counselling thus finds itself in a paradigm shift that increasingly stresses the influences of culture and sociopolitical context. One area in which the profession can advance a social justice agenda is through the school-to-work movement. In this article, directions for theory, research, and practice with secondary school-aged youth are discussed using a psychology of working perspective. Specifically, the roles of self-determination theory, critical consciousness, and social support are presented as synergistic mechanisms for fostering school engagement and preventing school dropout. To this end, higher education is viewed as a key institutional partner with programmes based inside and outside of the school.

AbstractDiencephalic amnesia can be as disruptive as the more commonly known temporal lobe amnesia, yet the precise contribution of diencephalic structures to memory processes remains elusive. We used discrete lesions of the mammillothalamic tract to model aspects of diencephalic amnesia and assessed the impact of these lesions on multiple measures of activity and plasticity within the hippocampus and retrosplenial cortex. Lesions of the mammillothalamic tract had widespread indirect effects on hippocampo-cortical oscillatory activity within both theta and gamma bands. Both within-region oscillatory activity and cross-regional synchrony were altered. The network changes were state-dependent, displaying different profiles during locomotion and paradoxical sleep. Consistent with the associations between oscillatory activity and plasticity, complementary analyses using several convergent approaches revealed microstructural changes, which appeared to reflect a suppression of learning-induced plasticity in lesioned animals. Together, these combined findings suggest a mechanism by which damage to the medial diencephalon can impact upon learning and memory processes, highlighting important role for the mammillary bodies in the co-ordination of hippocampo-cortical activity.
