First Annual Consumer Genetics Conference To Demystify Direct-to-Consumer Genetic Tests, Discuss Best Practices And Provide Forum For Dialogue
With consumer genetics becoming more of a reality to the average consumer and direct-to-consumer (DTC) genetics tests becoming more available, thought leaders, experts and DTC companies will convene in Boston on June 9-11 for the first annual Consumer Genetics Conference to move the issues to the forefront and demystify this emerging field. Preeminent leaders from government, healthcare, biotechnology and diagnostic fields, will examine consumer genetics, including its practical realities and complex policy considerations; speakers and companies will present new advances and information on available genetic tests and developments in this field. The conference is open to all who are curious, impacted by, and interested in consumer genetics, including consumers (http://www.consumergeneticsconference.com).

A Novel Approach For Treating Cognitive Impairments Identified By Animal Model For Schizophrenia
Researchers have been seeking a safe and effective way to treat cognitive impairments associated with schizophrenia by enhancing N-methyl-D-aspartate (NMDA) glutamate receptors. Functional deficits in NMDA receptors may contribute to the underlying neurobiology of this disorder. The first generation of studies trying to stimulate NMDA receptors administered large amounts of substances, like glycine or D-serine, which indirectly enhance NMDA receptor function. While there were some positive reports of efficacy, findings across studies were more inconsistent than was hoped.

Post-Surgery Distress In Children Eased By Hormone Treatment

A scary unknown for many children, the prospect of surgery can cause intense preoperative anxiety. While some amount of stress is normal, what many parents do not know is that extreme anxiety before surgery can contribute to the occurrence of emergence delirium, a distressing incidence of acute behavioral changes experienced when "waking up" from anesthesia. Now in the July issue of Anesthesiology, physicians focused on reducing anxiety in children and their families report that oral treatment with melatonin before surgery can significantly reduce the occurrence of emergence delirium in children. Affecting up to 20 percent of children who undergo surgery, emergence delirium in the post-anesthesia care unit (PACU) consists of acute behavior changes including crying, thrashing and need for restraint. According to researchers, this can also lead to the development of behavioral changes outside the recovery suite with the onset of nightmares, bed wetting and separation anxiety. "Studies conducted in adults have revealed that oral administration of melatonin before surgery beneficially reduced anxiety levels, but relevant similar treatment data for children undergoing anesthesia and surgery are limited," said study lead author Zeev N. Kain, M.D., MBA, Chair of UC Irvine Anesthesiology and Associate Dean for Clinical Research at the UC Irvine School of Medicine. Seeking confirmation of additional options for anxiety management, researchers first set out to determine if melatonin could decrease anxiety levels when compared to midazolam, a sedative widely used to ease preoperative anxiety. Melatonin is a hormone secreted by the pineal gland, regulates sleep, moods and reproductive cycles. Secretions of melatonin increase during exposure to light. In a study group that consisted of 148 subjects between the ages of 2 and 8 undergoing outpatient surgery under general anesthesia, children were randomly assigned to receive midazolam or melatonin orally before surgery. Children were followed throughout their surgical experience as researchers measured anxiety and secondary study outcomes of anesthesia administration compliance and emergence behavior. Behaviors were measured using the Yale Preoperative Anxiety Scale (mYPass), the Induction Compliance Checklist and the Keegan scale. "Results indicated that preoperative melatonin administration did not effectively reduce anxiety levels," said Dr. Kain. "However, it was found that melatonin significantly reduced the incidence of emergence delirium in these children. As 3 million children undergo surgery in the U.S. each year, these findings reveal noteworthy health care and treatment implications." Melatonin showed a direct dose dependent effect on emergence delirium. Children in the melatonin premedication group received any of three doses of melatonin: 0.05 mg/kg, .2 mg/kg and 0.4 mg/kg, while the incidence of delirium at each dose was 25 percent, 8.3 percent and 5.4 percent. Midazolam remains the recommended premedication for anxiety reduction in children scheduled for surgery. Tom Vasich University of California - Irvine
