You are being asked to take part in this research study because you have been diagnosed with pulmonary sarcoidosis. Sarcoidosis is a disease that can affect the lungs, skin and other organs of the body. Sarcoidosis also involves immune cells which fight bacteria. The purpose of this study is to see if using specific antibiotics will help these immune fighting cells get rid of bacterial proteins and how the antibiotics affect respiratory (breathing) function. The antibiotics used in this study are Levaquin, Ethambutol, Azithromycin, and either Rifampin or Rifabutin. You will by chance be assigned either these medicines or a placebo (an inactive substance).

Newborns who are born premature or suffer brain injury at birth are at risk for motor problems that may cause weakness in reaching and grasping on one side of the body. In older children, therapists may use a hand mitt and restraint for the stronger arm, to encourage use of the weaker side, called constraint-induced movement therapy (CIMT). Even with the high intensity therapy of CIMT, it typically takes between 40-120 hours total treatment time for most children to improve their motor skills. A non-invasive form of nerve stimulation, transcutaneous auricular vagus nerve stimulation (taVNS), stimulates a nerve by the ear that enhances learning motor skills. taVNS stimulation will be triggered by EMG sensors which detect muscle activity. The purpose of this study is to evaluate the safety and effectiveness of taVNS to improve motor skills when paired with CIMT in infants with one-sided weakness at 6-24 months of age.

The ECHO Cohort is a longitudinal prospective multi-site study aiming to understand how the environment and things that happen early in children's lives - even before they are born - affect their development, health, and well-being. This research program includes many study sites across the United States. ECHO will combine information about 20,000 pregnant participants, more than 50,000 children, and their families. With so many participants from across the country, researchers can answer important childhood health questions.

This study will include individuals who complain of a softer speaking volume due to their diagnosis of Parkinson's disease. Participants will receive the standard of care for voice therapy for persons with Parkinson's disease. Voice therapy will be provided three days a week, one hour per session, for 6 weeks. At the start and end of treatment, participants and their caregivers will complete surveys and questionnaires. The surveys and questionnaires will tell us about the impact of your Parkinson's disease diagnosis on the family unit, spousal relationship, communication, and quality of life. Three months after treatment ends, participants and caregivers will participate in a brief structured interview to discuss the supports and barriers to maintaining the vocal exercise program.

This study aims to investigate innovative approaches to managing chronic pain and opioid use. This study consists of two phases, each offering different treatment options. Participation is voluntary.

This study will sequentially evaluate three novel and scalable interventions for at-risk individuals on long term opioid therapy for chronic pain: (1) low-dose transdermal buprenorphine initiation without a period of opioid withdrawal; (2) a brief Cognitive Behavioral Intervention for pain (CBI); and (3) transcranial magnetic stimulation by examining standardized repeated measures of clinical outcomes at baseline, during treatment, and at follow-up.

Phase 1:
In this initial phase, all participants will have a 1-week open-label trial of buprenorphine (worn as a patch on the arm, shoulder or upper-back). This trial aims to assess the safety and effectiveness of buprenorphine in managing chronic pain and opioid use. During this phase, participants will have the opportunity to experience the effects of buprenorphine under close monitoring.

Phase 2:
After completing Phase 1, participants will have the opportunity to choose their next course of treatment. They can decide to continue with buprenorphine, and undergo a 1-week trial of either real buprenorphine or a placebo (an inactive substance). They will be randomly assigned to receive either real or placebo buprenorphine. If participants respond well to buprenorphine treatment, they may continue the medication under the care of their physician.

Alternatively, participants can explore an alternative treatment called repetitive transcranial magnetic stimulation (rTMS) in Phase 2. If they opt for rTMS, they will receive either real rTMS or a sham version interspersed with cognitive-behavioral therapy for pain. Participants will be randomly assigned to receive either real or sham rTMS.

In both phases, participants will receive close monitoring and attend regular study visits to assess safety and progress. Throughout the study, they will be asked to complete questionnaires about pain, functioning and opioid use, undergo physiological monitoring and blood samples will be collected at specific points.

It's important to note that there are potential risks associated with the study medication, such as difficulty sleeping, nausea, and dizziness. Additionally, for the rTMS arm, there is risk of mild headache, pain at the stimulation site, and there may be unknown risks related to the brain stimulation.

Participants' experience in Phase 1 will involve an open-label trial of buprenorphine, and participants' decisions in Phase 2 will determine the treatment path. While the effectiveness of these treatments is uncertain, participants will receive thorough monitoring throughout the study, and have the option to withdraw at any time. Improvement in participant symptoms is possible but not guaranteed.

This project examines how to improve speech understanding with cochlear implants (CIs), particularly for older CI recipients. While older individuals benefit from CI technology, performance is poorer than that of younger implanted adults for difficult listening tasks. The mechanisms that contribute to this variability are not well-understood. The current project examines how differences in brain structure and function may contribute to success with a cochlear implant. To compare, we will also be examining how older patients without cochlear implants understand speech in difficult listening situations.
