This is a smoking cessation treatment study. Patients who have a cancer or a suspected cancer who will undergo surgical removal of their cancer are eligible to participate in this study. A novel smoking cessation treatment will be provided to half of the participants in the study. All study participants will receive standard smoking cessation therapy including counseling and the nicotine patch.

The largest published COVID-19 pediatric series to date included only 13 patients considered to be critically ill and only described the Chinese outbreak. There are essentially no data outside of this and nothing to begin to understand the prevalence of severe/critical pediatric COVID-19, the risk factors associated with this illness, outcomes from COVID-19, and factors (patient or treatment) that may be associated with an improved or worsened outcome. This study will identify all children admitted to an inpatient unit with a diagnosis of COVID-19. Clinical data will be collected through medical record review to describe in detail the demographics and clinical characteristics, including clinical course and treatment, of infected children who require hospitalization.

This is an observational study that will analyze electronic health records data from real-world populations and settings in order to fully characterize the outcomes of Lung Cancer Screening with Low-Dowse CT scans.

This study is for patients that have been diagnosed with non-small cell lung cancer. The purpose of this study is to find out if a targeted immunotherapy treatment will have an effect on specific genes and proteins in tumors. This is a screening study in which a tumor sample will be submitted for testing. Based on results, the participant will be assigned to one of the treatment sub-studies.

This study is for women who have experienced a sexual assault in the past one year and use alcohol. The research involves completing a five to seven week behavioral treatment for stress and alcohol use. Participants will complete surveys during visits. Participants may also be asked to complete brief daily assessments on their smart phones.

This research study will be evaluating whether liquid nitrogen sprayed on the cells lining the airways (cryotherapy) can reduce the mucus produced in the lungs of patients with chronic obstructive pulmonary disease (COPD). The study involves bronchoscopies, (placement of a lighted, flexible scope into the lungs) under general anesthesia to deliver the treatment to the lungs. The study is randomized such that 2/3 of individuals get the cryotherapy and the other 1/3 get a sham (control) treatment with no cryotherapy. Participants in the sham control group will be evaluated for eligible for cryotherapy at end of year one. The Study duration is 36 months. Those initially randomized to the treatment group, they will have 7 clinic visits and 2 treatment visits. Participants randomized to sham group will have 11 clinic visits and 4 treatment visits.

Meniere's disease is a common cause of vertigo that becomes more common with age. Unfortunately, Meniere's disease and vestibular migraine have significant overlap and are sometimes difficult to diagnose. This is due to a lack of understanding of the true cause of Meniere's disease. Due to the lack of a biomarker (an objective test), the diagnosis of Meniere's disease has been based on clinical history and hearing loss. We are exploring ways to differentiate Meniere's disease and vestibular migraine, potentially through a lab test. In addition, identifying biomarkers may help early diagnosis and direct more personalized treatment strategies, especially early on before hearing loss occurs.

The purpose of the first portion of this study is to gather feedback from clinicians on the usability of the current system and procedure, so the researchers can make reflex training more useful and usable for improving recovery after spinal cord injury or other nervous system injuries and diseases. The researchers are recruiting 20 therapists who have been actively practicing physical medicine and 30 adults with no known neurological conditions to test system usability and the reflex operant conditioning protocol. For this portion of the study, there are 5 visits. We will also recruit 15 adults with no neurological injuries, 15 adults with neuropathic pain, and 15 adults with non-neuropathic pain to participate in one visit to provide feedback on sensation caused by stimulating electrodes.

The purpose of the second part of the study is to validate the capacity of the system to change the size of the targeted reflex. For this the researchers are recruiting 25 individuals with chronic incomplete SCI who have spasticity in the leg to participate in the reflex training procedure. The study involves approximately 45 visits with a total study duration of about 6 months.

This randomized clinical trial is designed to test the efficacy of ZA-5 mg in PD patients. This trial will also address barriers to treatment of patients with PD by providing rigorous evidence about whether ZA reduces fracture risk in patients with PD, simplifying treatment by giving ZA at home without extra medical visits and BMD testing, and overcoming poor persistence with oral therapies because one infusion may prevent bone loss for at least 2 years. The outcome of this trial will demonstrate how a home-based fracture prevention can reach older PD patients who would not otherwise receive treatment to reduce their high risk of fractures.

The PHAR is a multicenter, prospective registry of newly evaluated patients at PHCCs in the United States who have either PAH or CTEPH. Baseline information will be collected at the time of initial evaluation at the PHCC (within six months of the initial outpatient PHCC visit) with follow-up data collected at approximately 6-month intervals. This study will determine how patients with PH are evaluated, tested, and treated, and will observe how well patients do. The goal of the project is to see if patients with PH are treated according to recommended guidelines and to see if there are certain factors which lead to better or worse outcomes in patients with PH. There is no intervention or study medication used and there is no limitation to how a patient is treated in this study.
