This phase IV trial studies whether there is a relationship between how a patient is positioned while receiving bacillus Calmette Guerin (BCG) within the bladder (intravesical) and how long BCG stays in the bladder (dwell time) to improve the treatment of non-muscle invasive bladder cancer. For the past 40 years, intravesical BCG has been used for the treatment of non-muscle invasive bladder cancer. An important factor for BCG treatment is the dwell time, which is the period of time a patient can hold the BCG medication in the bladder after it has been given. Normally, patients are instructed during intravesical BCG treatment to avoid emptying the bladder for 2 hours after the BCG is given. However, this may be difficult for some patients who may have limited bladder capacity, restricted movement, or severe urinary symptoms. There have been studies outlining the relationship with increased dwell time and how well the treatment works, but studies on the potential impact of patient positioning or activity on the patient's ability to retain the drug are limited. Researchers hope by studying whether there is a relationship between patient positioning during intravesical BCG treatment and dwell time, they may be able to improve how BCG treatment for non-muscle invasive bladder cancer is given, especially for patients with limited bladder capacity, restricted movement, or severe urinary symptoms.

End stage liver disease or cirrhosis is a major cause of mortality in the United States and the world. Other than targeting the underlying cause, such as alcohol cessation and antiviral therapy, very few medical treatments can change the natural history of cirrhosis. Malnutrition is one of the few potentially modifiable factors that have been associated with cirrhosis severity and poor prognosis. The transition metal copper (Cu) is an essential trace metal that must be acquired from diet. Its metabolism is primarily regulated by the liver in its role as a master regulator of nutrients. In 2019, the investigators reported that Cu deficiency defined by below normal serum or liver concentrations occurred in a wide range of liver disorders and was associated with a severe disease phenotype. Improvement in liver function was observed in 2 of the 3 patients who received Cu supplementation. In 2023, the investigators conducted a longitudinal cohort study utilizing clinical, serum and liver explant tissue data from 183 cirrhosis patients. The investigators showed that Cu deficiency was associated with 2-fold higher infection rate and a more than 3-fold increase in the risk of death compared to patients with normal Cu status. These preliminary findings and the well-established importance of Cu in human health prompted the investigators to design the current pilot randomized, placebo-controlled, crossover trial to determine the effect of Cu supplementation on Cu dependent biochemical changes, patient safety and patient reported outcomes in cirrhosis.

This study is a prospective cohort study which aims to assess patient satisfaction and preparedness for surgery through two methods of preoperative counseling: standard individual phone calls versus virtual group sessions called Shared Medical Appointments (SMAs). The study will focus on patients undergoing urogynecology prolapse surgeries at Cleveland Clinic. Researchers hypothesize that virtual group counseling will improve patient satisfaction and preparedness compared to individual phone calls. Additionally, the study will evaluate healthcare resource utilization as a secondary outcome. Participants will complete surveys before and after surgery to measure satisfaction and preparedness using validated tools. The study will enroll patients aged 18 and older who can provide informed consent and are scheduled for specific prolapse surgeries. Findings may help improve preoperative counseling practices and enhance patient-centered care.

Cyclic vomiting syndrome (CVS) is a fairly common disorder characterized by relentless episodes of vomiting followed by return to baseline health.The majority of children with CVS have concurrent severe abdominal pain and migraine-features, causing significant disability during the attacks. There are very few non-drug treatment options for CVS. Many patients are treated with antidepressants that are often ineffective and may cause serious side effects. Emergency room visits and hospitalizations for patients with CVS is extremely high and the syndrome has an immense impact on quality of life. Safe and effective, non-pharmacological therapies for children with CVS are greatly needed. Nausea, vomiting and gastrointestinal pain is modulated by the vagus nerve, an important regulator of the autonomic nervous system. The vagus communicates signals between the gastrointestinal tract and the central nervous system. Many studies indicate that vagal nerve stimulation is effective for various pain and vomiting conditions. Recent studies show that vagus nerve signaling is impaired in children with CVS. Researchers have demonstrated safety and efficacy of auricular percutaneous electrical nerve field stimulation (PENFS) targeting the vagus nerve in a small study of children with CVS. The aim of the current study is to investigate the effects of non-invasive PENFS on CVS episode frequency, duration and severity compared to a sham device in a randomized clinical trial.

This study will examine how two important brain circuits - one involving the subthalamic nucleus (STN) and one involving the ventral intermediate nucleus of the thalamus (VIM) - contribute to learning and producing speech sequences. Participants will include two groups: 1. individuals with Parkinson's disease who have deep brain stimulation (DBS) devices targeting the STN and 2. individuals with essential tremor who have DBS devices targeting the VIM. Participants will complete speech tasks involving the learning and repetition of novel sound sequences. During some parts of the study, DBS stimulation will be temporarily turned on or off in a controlled research setting. This will allow researchers to examine how stimulation affects both the learning of new speech sequences and the production of previously learned sequences. All STN participants and most VIM participants will also be equipped with a cutting-edge DBS system, the Percept PC, which will enable the recording of deep brain activity during the tasks. The results of this study will improve our understanding of how different brain circuits support speech learning and production. In particular, this study will help to differentiate the roles of the STN and VIM in learning the ordering of speech sounds within a syllable from learning of speech sequences containing multiple syllables. This knowledge may help guide future approaches to optimizing DBS settings to improve both movement and speech outcomes in individuals with neurological disorders, as well as provide greater general insight into how these brain structures contribute to speech production and learning.

The purpose of this study is to assess the effectiveness and safety of a single dose of IPN10200 compared to placebo (double-blind phase) and how well and safely repeat doses of IPN10200 work over time (open-label phase) in adult participants with moderate to severe glabellar lines. Glabellar lines are wrinkle-like lines that appear between the eyebrows and can become more noticeable with age or repeated facial expressions. They may affect a person's appearance and confidence. All participants in the double-blind phase will receive IPN10200 or placebo during the first treatment cycle. De novo participants in the open-label phase will receive IPN10200 during the first treatment cycle. Some participants may receive additional treatment cycles with IPN10200 depending on their eligibility. There will be 3 periods in this study: - A screening period (up to 20 days) to assess whether the participant can take part, requiring at least 1 visit to the study centre. - A treatment period where participants may receive up to 4 treatment cycles. In the double-blind phase, participants receive a single treatment of IPN10200 or placebo. In the open-label phase (rollover participants from double-blind), eligible participants may receive additional cycles of IPN10200. In the open-label phase (de novo participants), participants will receive IPN10200 in the first cycle and eligible participants may receive additional cycles of IPN10200. Requires multiple visits during the first month followed by 1 visit every month. - A follow-up period (24 weeks) after the last injection where participants' health will be monitored. Participants will undergo health measurements and observation, including blood sampling, physical examinations, clinical evaluations and electrocardiograms (ECG: recording of the electrical activity of heart).

Micronutrient deficiencies are common in ulcerative colitis (UC). Selenium deficiency is associated with worse disease outcomes including disease flares and need for surgery. Previous in vitro and in vivo studies demonstrated that selenium regulates colonic inflammation, and that selenium supplementation protects against DSS-induced colitis. In this proof-of-concept clinical trial, we aim to test the hypothesis that selenium supplementation in moderate to severely active UC patients will improve responsiveness to advanced therapy such as biologics and small molecules.

Macular dystrophies are a group of inherited eye conditions that affect the macula. The macula is in the center of the retina, the light sensitive part at the back of the eye. In people with macular dystrophies, some of the cells in the macula gradually stop working and may die over time. This leads to vision loss in the center of the eye. Side vision (peripheral vision) is mostly unaffected. Stargardt disease (STGD) is a type of macular dystrophy which is caused by 1 faulty gene (ABCA4). Vision loss most typically happens in childhood, but many people do not develop it until they are adults. As well as STGD, there are other macular dystrophies that look very similar to STGD but that are caused by many other different genes. Together, STGD and STGD-like conditions can be called STGD-type macular dystrophies. This is because they look the same clinically and have similar symptoms. Since different genes can cause these conditions, genetic testing is the only way to be sure which specific condition a person has. In this study, researchers want to learn if the disease progresses in a similar way in people with STGD and STGD-like macular dystrophies. People taking part in the study will continue to manage their condition, as agreed with their own doctor. People will visit their clinic every 6 months to have various standard eye tests and imaging. The information collected will include questions about people's wellbeing, general health, medication and supplements taken, and daily activities. Children over 6 years old and adults with STGD-type macular dystrophies may take part in this study. They will be in the study for up to 24 months (2 years). The study sponsor (Astellas) will not decide how people's condition is managed. However, the sponsor will provide instructions on when people visit their clinic and what is recorded during the study. If available, medical records, clinical and imaging data from previous visits going back 24 months will also be reviewed.
