The main goal is to study the effects of internet-delivered cognitive behavioural therapy with minimum guidance for comorbid sleep problems in alcohol use disorder, in routine addiction care.
To elucidate factors affecting survival of early stage ovarian cancer
The investigators will test the hypothesis that auditory stimulation (playing quiet sounds during sleep) can normalize brain activity during sleep and improve memory in patients with schizophrenia. The investigators will do this by measuring sleep and memory performance under two conditions separated by one week: receiving auditory stimulation during sleep and not receiving auditory stimulation during sleep. The investigators will study healthy subjects and outpatients with schizophrenia.
The study aims to develop a test for early detection of ovarian cancer using DNA from a growth involving the ovary found in a washing of the uterus (womb), and proteins found in the blood. The samples of the wash and the blood will be taken before surgery. After surgery, doctors will determine whether the participant had ovarian cancer or a benign disease of the ovaries. The tests of the washings and the blood will be examined to see how much the participants with ovarian cancer can be separated from the participants with a benign ovarian disease by the tests. Small amounts from the washing and the blood samples will be sent to four sites for analysis. Statistical analyses of these data will compare tumor DNA found in the washing of the uterus with proteins in the blood to detect cases of ovarian cancer. The primary goal is to find tests that are mostly positive for cases of ovarian cancer and mostly negative for patients with benign disease. It is hoped that if the tests work for participants with symptoms of the disease that these tests will also work when testing women who have no symptoms. A new study would be needed to see if the tests worked in this situation. If the tests work, this could lead to increasing the number of cases detected in early stage disease and decreasing the number of cases detected in late stage disease. If this change in late stage is large, it will likely reduce deaths due to ovarian cancer.
This is a phase II, open-label, single center study, aiming to investigate safety and efficacy of anlotinib in treatment of recurrent high-grade glioma.
The novel coronavirus (SARS-CoV-2) infection (COVID-19) has caused a worldwide pandemic. There is still much that is unknown regarding the virus, especially its effects on pregnancy, the fetus, and the neonate. This study seeks to evaluate adverse pregnancy and neonatal outcomes related to COVID-19 infection. The FDA has authorized emergency use authorization for the SARS-CoV-2 messenger ribonucleic acid (mRNA) vaccines from Pfizer and Moderna. Pregnant women were excluded from the Phase III clinical trials of the mRNA vaccines. There are no studies that have evaluated functional antibody responses, antibody reactivity to variant viruses, T cell frequencies or activity, or protection against infection or development of COVID-19. Having a more detailed understanding of how pregnancy and lactation alters the longevity, specificity, and activity of antiviral antibody and T cell-mediated immune responses to COVID-19 mRNA vaccines is essential for the FDA to inform future recommendations and regulation of these vaccines.
Phase I dose escalation period: solid tumors, including but not limited to biliary tract cancer, pancreatic cancer, ovarian cancer, thymoma, neuroendocrine carcinoma and other advanced solid tumors. Phase II trial period: biliary tract cancer
This phase II trial studies how well nab-paclitaxel, durvalumab, and tremelimumab with or without personalized synthetic long peptide vaccine (neoantigen vaccine) works in treating patients with triple negative breast cancer that has spread to other places in the body (metastatic). Chemotherapy drugs, such as nab-paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Vaccines made from peptides may help the body build an effective immune response to kill tumor cells. It is not yet known whether giving nab-paclitaxel, durvalumab, and tremelimumab with or without neoantigen vaccine will work better in treating patients with triple negative breast cancer.
Apathy is a neurocognitive syndrome characterized by reduced goal-directed behaviors, contributing to decreased patient and caregiver quality of life. Apathy pathophysiology involves disruption of cortico-striato-thalamo-cortical loops, modulated by several neurotransmitter systems including dopamine and acetylcholine, thus complexifying pharmacological management. Post-stroke apathy (PSA) can provide a proper in vivo model to study the underlying neurochemical substrates of apathy as a syndrome. The present project aims to provide a better characterization of the cholinergic and dopaminergic functioning in apathy as a syndrome. In order to precise the respective alterations of these two systems, investigators will use a positron emission tomography (PET) molecular imaging of dopaminergic (with [18F]-FDOPA, a marker of the decarboxylating enzyme of dopamine) and - for the first time in apathetic patients - cholinergic (with [18F]-FEOBV, a marker of the vesicular acetylcholine transporter) transmissions in 15 apathetic and 15 unapathetic patients 3 months after stroke, without overlapping depression. This dual imaging study may provide help in guiding therapeutic management of PSA. The functional network analysis allowed by functional MRI is crucial to complement regional neurotransmitter deficits observed with PET. Altogether, a multimodal approach in apathy, combining PET and MRI, can allow identifying which circuits of the cortico-striato-thalamo-cortical loops are disrupted and how these circuits are modulated by other neurotransmitters.
Advancing Postmenopausal Preventive Therapy (APPT) is a randomized, double-blinded, placebo-controlled trial designed to determine the effects of tissue selective estrogen complex (TSEC) therapy on the progression of subclinical atherosclerosis and cognitive decline in 360 healthy postmenopausal women.
