There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Prostate cancer is the most common cancer diagnosed in men in the USA with 268,490 cases diagnosed in 2022 constituting 27% of male cancers and 34,500 deaths (11%) occurred in same year.1 Prostate cancer is a very heterogeneous disease that has different presentations, molecular and pathological features, stages, and disease biology. The treatment options are dependent on the disease stage, its features, and the patient's condition and preferences. The disease outcome also varies significantly due to the previous heterogeneity of the features in addition to other social determinants of health. Therefore, it is critical to obtain real-world data that reflects the actual patterns of prostate cancer presentation, work up, management, and outcome. Real World Prostate Cancer Registry (RWPCR) aims at compiling real world data from patients presented with prostate cancer in the tristate area. The data collection will be prospective and longitudinal including patients' demographics and disease characteristics, work up, management, and outcome.
The goal of this clinical trial is to learn more about the interaction between a patient in the hospital and their treating doctor. A good relationship between patients and their doctors can help improve patient care. Doctors will be asked to use strategies to improve their interactions with patients in the hospital. The main questions it aims to answer are: - Will using the intervention strategies improve doctors' empathy towards their patients? - Will using the intervention strategies lead to improved scores in patient views of doctors' empathy? There will be 2 study arms. One group of doctors will be asked to use the intervention strategies. The other group of doctors will provide care as they would normally. Researchers will compare the doctors in the intervention arm to those in the control arm. Doctors are the primary subjects for this study. The doctors in both study arms will be asked to do the following: 1. Allow study staff to observe the interaction between them and their patients. 2. Complete a brief survey at the end of their 2-week work rotation. Doctors who are in the intervention arm will be asked to use suggested strategies when visiting with patients in the hospital. Patients are secondary subjects for this study. Patients of participating doctors may be asked to do the following: 1. Allow study staff to observe the interaction between them and their doctors. 2. Complete a brief survey after meeting with their doctor.
The primary objective is to characterize the tolerability of TMS by scalp location (over parietal, motor, modified Beam F3 prefrontal, THREE-D prefrontal, orbitofrontal, and medial prefrontal) and stimulation parameters (single pulse, 10 Hz, theta burst). The secondary objective is to evaluate the knee as a surrogate location to safely trial tolerability of novel TMS parameters.
The purpose of this study is to investigate the efficacy and safety of retatrutide compared with placebo in participants with Type 2 Diabetes and inadequate glycemic control. The study will last about 11 months and may include up to 11 visits.
This study will validate recently developed Magnetic Resonance Imaging (MRI) and Ultrasound (US) based methods for liver fat quantification in children with obesity and healthy range of body mass index (BMI).
This qualitative study investigates the potential benefits and challenges of using a once-a-month injectable medication, known as extended-release buprenorphine (XR-B), to treat individuals with opioid use disorder (OUD) within a correctional setting. The research aims to understand if XR-B can be a feasible and effective alternative to the standard daily treatment and to identify which groups within the prison population may benefit the most from this treatment. In-depth interviews are conducted with incarcerated individuals and relevant stakeholders.
The goal of this clinical trial is to understand how the blood sugar-lowering hormone insulin works in healthy adults versus those who are at risk for type 2 diabetes. The study will use a drug called alpelisib, which interferes with insulin's actions in the body, to answer the study's main question: does the liver continue to respond to insulin's stimulation of fat production even when it loses the ability to stop making glucose (sugar) in response to insulin. Researchers will compare the impact of single doses of both alpelisib and placebo (inert non-drug) in random order (like flipping a coin) in study participants. Participants will be asked to stay twice overnight in the hospital, take single doses of alpelisib and placebo (one or the other on each of the two hospital stays), and receive intravenous (into the vein) infusions of non-radioactive "tracer" molecules that allow researchers to measure the production of glucose (sugar) and fats by the liver. Measurements will be done both overnight, while participants are asleep and fasting (not eating or drinking other than water) and while consuming a standardized diet of nutritional beverages during the following day. The objective is to evaluate the effect of lowering insulin levels, while maintaining constant mild hyperglycemia, on plasma glucose and lipid levels.
This study will examine a potential relationship between family history of obesity, that is whether people with at least one parent who had obesity in adulthood compared to people with two parents who did not have obesity in adulthood, and the ability of protein intake to curb further intake of food.
The primary aims of this study are to compare, after 6 months, the clinical and histologic results of intra-marrow penetrations vs no intra-marrow penetrations when performing guided bone regeneration procedures.
- The goal of this clinical trial is to learn about medication adherence to difference types of vaginal estrogen in women with low levels of estrogen (for example, post-menopausal women) who have recurrent urinary tract infections. Medication adherence means whether patients take their medicine as prescribed. - Another goal of the study is to learn about changes to the skin of the vagina before and after estrogen treatment, using a specialized imaging modality called optical coherence tomography, which is similar to receiving an ultrasound. - A third goal of the study is to learn about changes to the microbiome (all the bacteria that naturally live in our bodies) before and after treatment with vaginal estrogen. The researchers will be looking specifically at the microbiome in the urine and the vagina. Participants will be assigned by chance (like the flip of a coin) to receive one of three possible vaginal estrogen treatments - cream, tablets, or drug-eluting ring. - The main study tests and procedures include an initial visit in which the researchers will collect baseline information about participants and have participants complete a series of questionnaires. - There will then be 3 and 6 month follow-ups in which the researchers will have participants complete additional questionnaires and the researchers also assess whether participants are using the vaginal estrogen treatment that you were prescribed. If a participant is part of the microbiome cohort, they will also be asked to do the following: - a baseline visit in which urinary and vaginal specimens are collected to assess their baseline microbiome. The vaginal specimen collection will involve a q-tip swab inside the vagina; it is similar to a pap smear. - Finally, participants will have an imaging modality performed on their vagina called optical coherence tomography, which allows the researchers to assess the thickness of the vaginal walls and the blood vessel density. This imaging modality involves the insertion of a thin probe into the vagina to obtain the images of the vaginal wall. - These tests will then be repeated at 6 months to assess if vaginal estrogen treatment causes changes to the vagina.
