Neural Bases of Vocal Sensorimotor Impairment in Aphasia
Recruiting
Aphasia is the most common type of post-stroke communication disorder characterized by deficits in speech comprehension, production and control. While recovery can be promoted with speech therapy, improvement remains modest and typically requires a large number of sessions contributing to rising health care costs. Traditional aphasia therapy focus on enhancing speech motor output; however, recent evidence suggests that the auditory feedback also plays a critical role in fluent speech. Therefore,... Read More

Osimertinib Alone or With Chemotherapy for EGFR-Mutant Lung Cancers
Recruiting
This study will compare the effectiveness of osimertinib alone with the combination of osimertinib and chemotherapy (carboplatin and pemetrexed) in people with metastatic lung cancer that has a change (mutation) in the gene EGFR. Osimertinib alone is the usual treatment for metastatic EGFR-mutant lung cancer. Researchers think adding chemotherapy to osimertinib could possibly add to the anticancer effects of the usual treatment and help stop cancer from growing or spreading.

ChangeGradients: Promoting Adolescent Health Behavior Change
Recruiting
As most adolescents visit a healthcare provider once a year, health behavior change interventions linked to clinic-based health information technologies hold significant promise for improving healthcare quality and subsequent behavioral health outcomes for adolescents (Baird, 2014, Harris, 2017). Recognizing the potential to leverage recent advances in machine learning and interactive narrative environments, the investigators are now well positioned to design health behavior change systems that...
