Clinical trials

The purpose of this study is to assess the feasibility of a 4-week intervention combining exercise and transcranial alternating current stimulation (Ex+tACS) in breast cancer survivors who report experiencing cancer-related cognitive impairment. Feasibility will be assessed by measuring participant retention, adherence, satisfaction with the intervention, and safety. The researchers will also examine pre-to-post intervention changes in attention, executive function, working memory, perceived cognitive function, and physical function before, after, and four weeks post intervention completion in the Ex+tACS group compared to a control group who will receive exercise and a placebo tACS condition (CON).

The goal of this single-arm study is to learn if a dog adoption and training program can treat, prevent in \[describe participant population/primary condition; could include any of the following: sex/gender, age groups, healthy volunteers\]. The main questions it aims to answer are: * Does the dog adoption and training program decrease posttraumatic stress symptoms in veterans with self-reported posttraumatic stress symptoms? * Does the dog adoption and training program decrease stress and improve psychosocial health in veterans with self-reported posttraumatic stress symptoms? * Does the dog adoption and training program decrease inflammation, increase oxytocin, and change the structure and resting-state function of specific brain regions in veterans with self-reported posttraumatic stress symptoms? Participants will: * Attend eight one-hour professional dog training sessions within a 10-week period. * Visit the clinical research unit four times during the study for data collection.

The goal of this observational study is to learn about the levels of nicotinamide adenine dinucleotide (NAD) in the brains of people with Alzheimer's disease. The study aims to determine if brain NAD levels are lower in people with Alzheimer's disease compared with people of the same age group who do not have Alzheimer's disease. Participants with or without Alzheimer's disease will have a brain imaging session where NAD will be measured using magnetic resonance spectroscopy (MRS). Eight months later, they will have a second, similar, brain imaging session.

The goal of this project is to determine whether pharmacogenomic testing (using participants' DNA) can help optimize medication prescribing and reduce side effects in older adults taking five or more medications. The main questions it aims to answer are: * Can DNA-based prescribing reduce medication-related side effects, especially falls and fall-related injuries? * Does providing pharmacogenomic results to primary care physicians improve medication safety compared with usual care? Researchers will compare two groups: 1. DNA Care Pathway: Physicians receive patients' DNA results to guide prescribing. 2. Emergency Department Care Pathway: Physicians provide usual care; DNA results are shared only after study completion. Participants will: * Provide a cheek swab sample for DNA analysis (1 minute). * Receive monthly follow-up phone calls for 6 months to track falls, injuries, medication changes, and side effects. * Complete a fall and medication calendar. * Allow researchers to review primary care physician medical records for study outcomes. Approximately 1,000 participants will take part, with follow-up lasting about 6-7 months.

Diphenhydramine, when injected locally, has been shown to achieve a certain level of local anesthesia. It has been documented for use in simple bedside procedures, however there is a gap in knowledge in its comparison to lidocaine. The purpose of the study is to determine if local infiltration of diphenhydramine is noninferior to the use of lidocaine 1% when trying to achieve local anesthesia for simple laceration repair. Patients who present to the emergency department with a simple laceration will be enrolled in the study. Patients will be evaluated for the pain of the injection as well as the pain of the laceration repair procedure post injection.

The goal of this randomized controlled clinical trial is to \[learn about, test, compare etc.\] in critically ill or injured cohorts of patients presenting to the Emergency Department. The main question\[s\] it aims to answer are: * Are weight estimates from a 3D camera system more accurate than standard methods of weight estimation? * Do patients who receive weight estimates with a 3D camera system have fewer drug dosing errors than patients receiving standard care? Participants will either receive a weight estimate using a 3D camera system, or standard methods of care. Researchers will compare the 3D camera group to those with standard care to see if the weight estimates are more accurate, to see if drug dosing is more accurate, and to compare the incidence of adverse events related to medications in each group.
