Several new guidelines and position papers offering the most up to date information to ensure that clinicians practice evidence-based medicine were released at the Canadian Cardiovascular Congress 2009 this week. Among them are the following: 2009 CCS Canadian Cholesterol Guidelines 2009 CCS Consensus Conference Update on the Guidelines for the Management of Adults with Congenital Heart Disease CCS/Canadian Association of Radiologists Consensus Training Standards for Cardiac CT 2009 CCS Heart Failure Guidelines Guidelines are one of the highest priorities of the Canadian Cardiovascular Society (CCS), says their president Dr. Charles Kerr. "They are one of our most important services and are the highest rated by clinicians, " he says.
Liquorice Consumption In Pregnancy May Affect Eating Liquorice In Pregnancy May Affect A Child's IQ And Behavior
Expectant mothers who eat excessive quantities of liquorice during pregnancy could adversely affect their child's intelligence and behaviour, a study has shown. A study of eight year old children whose mothers ate large amounts of liquorice when pregnant found they did not perform as well as other youngsters in cognitive tests. They were also more likely to have poor attention spans and show disruptive behaviour such as ADHD (attention deficit hyperactivity disorder). It is thought that a component in liquorice called glycyrrhizin may impair the placenta, allowing stress hormones to cross from the mother to the baby. High levels of such hormones, known as glucocorticoids, are thought to affect fetal brain development and have been linked to behavioural disorders in children.
Researchers in the US found that exposure to tobacco in the womb and to lead during childhood was linked to a particularly high risk for Attention-Deficit/Hyperactivity Disorder ( ADHD ) in children, suggesting that while we tend to focus on treatment for ADHD, eliminating such exposures might prevent the condition in many hundreds of thousands of children. The study was the work of senior author Dr Robert Kahn, a physician and researcher at Cincinnati Children's Hospital Medical Center, Ohio, and colleagues, and was published online on 23 November in the journal Pediatrics. Kahn and colleagues estimated that up to 35 per cent of cases of ADHD in youngsters aged between 8 and 15 could be reduced by getting rid of both prenatal exposure to tobacco and childhood exposure to lead: in numbers this figure represents some 800, 000 children in the US population.
Video game players are often accused of passively reacting to tasks that are spoon fed to them through graphics and stimuli on the screen. A group of researchers from Iowa State University shows that playing lots of video games has different effects on two types of cognitive activity, proactive and reactive attention. Proactive attention can be thought of as a sort of "gearing up" mechanism. For instance, when players that are familiar with a particular game anticipate an action they need to take, such as getting a key or a pot of gold, in order to get to the next level. Reactive control is described as happening "just in time", for example, when a monster suddenly appears that is about to thwart the player's advantage or ability to get to the next level.
Rats exposed to high doses of amphetamines at an age that corresponds to the later years of human adolescence display significant memory deficits as adults - long after the exposure ends, researchers report. The declines in short-term or "working" memory are most pronounced when the rats are exposed during adolescence, rather than as adults, the researchers found. "Animals that were given the amphetamine during the adolescent time period were worse at tasks requiring working memory than adult animals that were given the same amount of amphetamine as adults, " said psychology professor Joshua Gulley, who led the study with graduate student Jessica Stanis.
Children exposed to tobacco in utero and to lead during childhood are eight times more likely to be diagnosed with attention deficit/hyperactivity disorder ( ADHD ), according to the first study to examine the combined effects of these exposures in U.S. children. The study, "Association of Tobacco and Lead Exposures with Attention-Deficit/Hyperactivity Disorder, " published in the December issue of Pediatrics (appearing online Nov. 23), examined records of prenatal tobacco and childhood lead exposure in the 2001-2004 National Health and Nutrition Examination Survey, a cross-sectional, nationally representative sample of U.S. children ages 8 to 15. Prenatal tobacco exposure was measured by report of maternal cigarette use during pregnancy, and lead exposure was assessed by current blood lead levels.
New Study On Vyvanse R lisdexamfetamine Dimesylate Capsules CII Shows Administration Of Vyvanse Through Two Different Routes
Shire plc (LSE: SHP, Nasdaq: SHPGY), the global specialty biopharmaceutical company, announced new data about the pharmacokinetics of its Attention-Deficit/Hyperactivity Disorder ( ADHD ) medication, Vyvanse ® (lisdexamfetamine dimesylate) Capsules CII, which showed that Vyvanse provided similar concentrations of its active medication in the blood when administered either intranasally or when administered orally. Specifically, the overall rate and extent of exposure to d-amphetamine, the active medication in Vyvanse, was similar in healthy adults whether they received the drug as a solution through the nose or orally as a capsule. These findings, which were recently presented at a major psychiatric meeting, reflect the ongoing efforts of Shire to further understand the abuse potential of Vyvanse.
Parents have long lectured their children about the mind-numbing effects of playing video games all day. And a new Iowa State University study has found that high volume action video game players -- those who play around 40 hours per week -- actually had more difficulty keeping focused on tasks requiring longer, more proactive attention than those who played video games less than a couple of hours a week. The study, published online this week in the latest issue of the professional journal Psychophysiology, also supports research published within the last year establishing a positive association between being addicted to playing video games and having Attention Deficit Disorder (ADD).
ADHD: Vyvanse Capsules CII Administration Through 2 Routes Demonstrated Similar Pharmacokinetic Profile

KemPharm, Inc. announced that it has commenced a Phase 1 clinical trial in healthy volunteers of its novel prodrug compound, KP106, which is in development for the treatment of attention-deficit hyperactivity disorder ( ADHD ). KP106, a new chemical entity (NCE) composed of d-amphetamine and a ligand, is the lead investigational candidate from KemPharm's proprietary ligand activated therapy (LAT) platform, which creates improved versions of FDA-approved drugs. KemPharm began the KP106 program in 2007 and has initiated the Phase 1 clinical trial of this candidate in less than 24 months. "Preclinical studies suggest that the prodrug properties of KP106 may offer an improved side effect profile, including reduced weight loss and cardiovascular effects, and decreased abuse potential compared with current amphetamine-based treatments for ADHD, " said Robert Karr, M.
