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.

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 is a research study to find out if smoking cessation medications, either varenicline or nicotine replacement products (patches or lozenges), are effective when given to smokers, remotely, as a one-time sample.

Participants will either receive a sample of varenicline, nicotine patches and lozenges, or neither. This will be decided randomly. Participants have a 50%chance of receiving varenicline, a 25% chance of receiving nicotine products, and a 25% chance of receiving neither. If the participant is assigned to a group that receives free samples, they will be mailed to them free of charge. There is no requirement to use them, and it is completely up to the participants. There is also no requirement to quit in this study.

The study lasts for six months, and will involve six total surveys. In addition, we ask that participants complete daily diaries (about 1 minute each) for the first 4 weeks of the study. Both varenicline and nicotine replacement products are well-established medications that help smokers quit.

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.

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.

Many adolescents experience traumatic events, such as child abuse, physical or sexual assault, or witnessing violence. Teens who experience trauma are more likely to have problems with substance use and risky sexual activity. We want to understand how parents can support their teens and help keep them safe after traumatic events.
