Shared-Decision Making for Hydroxyurea
Children's Hospital Medical Center, Cincinnati Sickle Cell Anemia Children, Only

The goal of the study is to understand how best to help parents of young children with sickle cell disease and their clinicians have a shared discussion about hydroxyurea (one that takes into account medical evidence and parent values and preferences). The study will compare two methods to help clinicians facilitate this-a clinician pocket guide and a clinician hydroxyurea shared decision making toolkit-in a group of parents of children ages 0-5 with sickle cell disease. The investigators hope that both methods lead to parents reaching a high-quality, well-informed decision. In addition, the team hopes to demonstrate that parents who experience a shared decision will have lower anxiety and decisional uncertainty. The researchers also expect these parents to be more likely to choose hydroxyurea and that their children will have less pain, fewer hospitalizations, better developmental outcomes, and higher quality of life. The project team hopes to show that the toolkit method is easy for clinicians to use and gives parents the support needed to make an informed decision.

Stress, Sleep and Cardiovascular Risk
Howard University Posttraumatic Stress Disorder Insomnia
We are evaluating a model where trauma exposure and threatening environments elicit nocturnal vigilance and sleep-related fears that compromise the healthy reduction of autonomic arousal during sleep which in turn stimulates secretion of atherogenic humoral factors, arterial... expand

We are evaluating a model where trauma exposure and threatening environments elicit nocturnal vigilance and sleep-related fears that compromise the healthy reduction of autonomic arousal during sleep which in turn stimulates secretion of atherogenic humoral factors, arterial stiffening, and cardiovascular disease risk. We will examine the roles of pre-sleep cognition using a questionnaire and real time assessment, and modifiable strategies for coping with sleep disruptive cognitions. We will then evaluate the impact of providing personalized feedback and recommendations based on study observations on how participants cope with potentially sleep disruptive cognitions and sleep efficiency in a randomized trial.

The risk of stroke and vascular dementia is high in individuals who have had a prior stroke or TIA, and in those who have vascular disease risk factors, such as high blood pressure, abnormal cholesterol, diabetes or pre-diabetes. These vascular risk factors can improve with exercise. This study will examine the impact of a 6 month, low intensity group exercise class on fitness, walking, balance, and brain health. This study will also collect fitness, walking, balance, and brain health outcome measures at baseline and post all other MERCE exercise and robotics interventions.
