NCT05133479
In the proposed project, the investigators will conduct a multisite randomized controlled trial (RCT) to determine the efficacy of Let's Know!2, a small-group, language focused comprehension intervention, on children's lower- and higher-level language skills and comprehension skills in the short- and long-term (Specific Aims 1 and 2). The investigators will also explore whether intervention effects are moderated by dosage, initial language skill, developmental language disorder (DLD) status, word reading skill, nonverbal IQ, and family socioeconomic status (Specific Aim 3). Children who have low language skills and are thus at risk for reading comprehension difficulties will participate in the study. Children will be randomly assigned to receive Let's Know! in small groups at their respective schools or to a business-as-usual control condition. The investigators will measure children's language and comprehension skills at the beginning and end of Grade 1 as well as in Grade 2 and Grade 3. The investigators hypothesize that children who experience Let's Know! will end Grade 1 with higher language skills than children in the control condition and that this will translate into better listening and reading comprehension skills as these children matriculate through elementary school.

NCT03613532
This clinical trial involves individuals who have been diagnosed with Acute Myeloid Leukemia (AML), Myelodysplastic Syndrome (MDS), Chronic Myelomonocytic Leukemia (CMML), or MDS/myeloproliferative neoplasm-unclassifiable (MDS/MPN-unclassifiable) and are planning to have an allogeneic hematopoietic stem cell transplant ("bone marrow transplant"). The goal of this research study is to (1) test the safety of adding the study drug, Venetoclax, to a standard of care conditioning regimen for bone marrow transplantation as a possible means of eliminating residual (left-over) disease prior to transplant, (2) to test the safety of combination Venetoclax and azacitidine as "maintenance therapy" after transplant to possibly prevent disease recurrence and (3) to test the safety of combination Venetoclax and oral decitabine/cedazuridine as "maintenance therapy" after transplant to possibly prevent disease recurrence. * The name of the study drug involved in this study is Venetoclax. * It is expected that about 102 people will take part in this research study.
NCT06238700
This study aims to identify how enhanced allopregnanolone activity (via pregnenolone) affects behavior and neurobiology that may underlie perimenopausal depression.
NCT03261089
Cardiovascular disease remains the leading cause of death in the United States. Mortality rates of cardiac arrest range from 60-85%, and approximately 80% of survivors are initially comatose. Of those who survive, 50% are left with a permanent neurological disability, and only 10% are able to resume their former lifestyle. Early prognosis of comatose patients after cardiac arrest is critical for management of these patients, yet predicting outcome for these patients remains quite challenging. The primary study objective of SPARE is to assess the value of using a systematic, multi-modal approach for neuroprognostication in the unconscious post-cardiac arrest population. We hypothesize that prognostication using this approach will be significantly improved compared to historical controls. This approach will be novel because: All patients who are unconscious at least 24 hours post-cardiac arrest, whereas previous studies on neurologic outcome tended to have restrictive inclusion criteria, such as no pre-existing neurologic impairment (e.g. dementia or prior cerebrovascular injury), or included an unduly restrictive population, such as patients with a strictly comatose state. The prognostic modalities used to assess patients will be applied at specific time points that will maximize their utility. Patients' families and clinicians will be encouraged to provide adequate time to allow for a delayed recovery, especially in cases of uncertain outcome, thus minimizing the self-fulfilling prophesy bias of early withdrawal of life-sustaining therapies (WLST). This will be particularly pertinent in the comparison of US and Brazil/Italy patients, as the Brazilian and Italian populations are not commonly exposed to premature WLST (as can be the case in the US), one of the major sources of biases in prognostication studies of cardiac arrest due to the self-fulfilling prophecy.

NCT06107426
Parkinson's disease (PD) is a neurological condition, which affects the brain. PD gets worse over time, but how quickly it progresses varies a lot from person to person. Some symptoms of PD are tremors, stiffness, and slowness of movement. The purpose of this study is to evaluate how effective ABBV-951 is in treating adult participants with advanced PD in real world setting. ABBV-951 (foslevodopa/foscarbidopa) is an approved drug for the treatment of Parkinson's Disease. The main ROSSINI study will have approximately 450 adult participants with PD (300 participants new to ABBV-951, up to 150 participants transitioning from open-label extension study) will be enrolled across approximately 60 sites. Decision to treat with ABBV-951 (or continue the treatment in Cohort B) will be made by the doctor prior to any decision to approach the participant to participate in this study. There will be a sub-study that will enroll 40 naïve participants who initiated Foslevodopa/Foscarbidopa treatment for the first time (Cohort A of the ROSSINI parent study only) from 6 to 15 centers in the United States, Germany and Spain. All participants will receive subcutaneous infusion of ABBV-951 for approximately 3 years. Participants will attend regular clinic visits during the course of the study. The effect of the treatment will be checked by medical assessments, and completing questionnaires.
NCT07080853

NCT05779475
The main purpose of this study is to follow and observe a group of people living with Parkinson's disease to see how study participation affects their signs and symptoms in the months after starting in the study. While taking part in this study participants will take their usual medication as prescribed. However, the study doctor may recommend adjustments to their medication to provide a better treatment of their Parkinson's disease. Participation will last from 3 up to 24 months. During visits to the clinic, the study doctor or study nurse will evaluate signs and symptoms of Parkinson's disease using several different assessments. At a minimum of 2 visits participants will be asked to undergo 'off'-assessments.

NCT02771236
Background: Genes are the basic units of heredity. When genes are changed, certain cells don t work like they should. Researchers want to try to better understand the genetic conditions that are linked with inherited eye diseases. Objective: To try to identify the genes linked to the development of inherited eye diseases. Eligibility: People ages 4 and older who have or have a family member with an inherited eye disease Design: Participants will be screened with medical history and medical records. Participants will have one visit that will take 3-4 hours. This will include: Medical and family history Eye exam: This includes the pupil being dilated. Electroretinography: A small electrode is taped to the forehead. Participants sit in the dark with their eyes patched for 30 minutes. Then numbing drops and contact lenses are put in the eyes. They will watch flashing lights. Blood tests Saliva sample: They will spit into a container or have the inside of their cheek swabbed. Genetic testing will be done on participants blood or saliva. Participants may meet with the researchers to discuss their genetic tests.
