Filter by:The purpose of the present RCT is to evaluate a 12-month SMS intervention with expanded content, intervention strategies and interactive database logic, novel online enrollment, and automatic baseline scoring of measures to support a 12 month weight loss SMS intervention. The investigators hypothesized that the intervention group would have greater weight loss at 6 and 12 months than the control group and increased adherence to SMS would be associated with greater weight loss at 6 and 12 months.
Migraine is one of the commonest neurological disorders, affecting up to 12% of the general population, but remains relatively under-diagnosed and under-treated. Migraine has a wide socioeconomic impact and brings a large economic burden; estimates suggest that disability due to migraine costs > €27 billion per annum across Europe. Despite its prevalence and impact, migraine pathophysiology is poorly understood. A wider understanding of the functional changes in this disorder would be beneficial to both diagnosis and treatment. Saccades are the rapid eye movements we make when moving the eyes to a new object in our visual field. Reaction time studies have been used to investigate Huntington's disease and Parkinson's disease with great success. These use saccadic tasks (monitoring eye movements). Even at rest we make approximately three saccades per second, so a lot of data can quickly be gathered with non-invasive testing. We hope to understand more of the underlying mechanisms of migraine by studying reaction time in migraine patients. Our previous pilot study, with less stringent inclusion and exclusion criteria, looked at fewer patients (32 migraineurs and 32 controls), and found that migraineurs showed significantly different saccadic patterns to non-migraineurs. This study firstly seeks to corroborate the saccadometric findings of our earlier pilot study in a group of migraineurs, and secondly to explore the specificity of these findings in migraine by also studying patients with another primary headache syndrome, namely cluster headache. Migraine is known to be a dynamic disorder, with previous studies showing longitudinal changes in the migraine brain. To explore this further we hope to record longitudinally (Every day for 21 days) in a small subset of migraineurs to identify potential longitudinal changes in saccadic reaction time. Because of the portability of the equipment this could be done in the subjects own home if they preferred.
This study examines youth's motivation for food or social rewards after a brief episode of simulated ostracism. The investigators hypothesize that youth who think about a friend after being ostracized will mediate their decision to resort to food, which is typically evidenced in socially isolated overweight youth.
The investigators aim to study potential racial differences in renal phosphorus handling by provocatively testing urinary phosphorus excretion using parathyroid hormone infusions in healthy white volunteers compared to healthy black volunteers.
Children diagnosed through the FAS DPN clinic (who receive non-study services through the clinic/referrals) will receive baseline assessment. The baseline assessment for the child will include: medical issues (including medication), intellectual assessment, academic achievement, language, social functioning, executive functioning, neurological assessment, perceived self-confidence, and behavioral observation of parent-child interactions (videotaped and coded). For caregivers, baseline assessment will include: demographics, medical histories, educational history, current services, satisfaction with services, knowledge of FAS, stress, parenting competence, and family functioning.
Children will be randomly assigned to a Parent-assisted social skills training or Wait list. Baseline and post intervention rating will be obtained from teachers.
