The purpose of this study is to determine if sodium lauryl sulfate (SLS), a non-drug ingredient commonly added in drug products, affect absorption of drugs that are given together with the ingredient. Investigators want to find out if drug absorption is different in people taking the drug alone compared to people taking the drug with low and high amounts of sodium lauryl sulfate at the same time.

The purpose of this project is to provide appropriate administrative and technical supports for the warehousing and use of a database of patients with coronary microvascular disease (CMD). This protocol will outline the process for identification and capture of data, storage, as well as data use and sharing internally and externally for research purposes. Read Less

Placement of a ureteral stent is a common urological intervention. For decades there was no valid measures available to assess quality of life issues in patients with ureteral stents, which has hampered the understanding of such symptoms and their true impact. In order to improve the outcomes associated with the placement of a stent, a validated tool is needed to measure its impact and the amount of undesirable effects it produces on patients requiring the placement of a stent. In 2003, the team of the Bristol Urological Institute developed a validated questionnaire called the: URETERAL STENT SYMPTOM QUESTIONNAIRE (USSQ). The questionnaire contains 38 items included in 6 sections. Despite the obvious need of a validated questionnaire, the latter remains unused by the community of peer urologists. Many of urologists consider it too long to be used in clinical practice and even for research purposes. This issue motivated the Canadian Endourology Group (CEG) to work collaboratively on the development of the CANADIAN ENDOUROLOGY GROUP STENT SYMPTOM SCORE (CEGSSS) in order to provide clinicians with a more useful and validated tool. To fulfill this objective, the CEG proceeds in three phases. Phase 1. A systematic, deliberative, and participatory approach mostly through face to face meetings, including patients, clinicians, and researchers in the field of Endourology to identify a minimum needs-based set of domains and items that are, clinically relevant to be included in the CEGSSS in order to ensure optimal uptake in the clinical setting. Phase 2. A pilot study to assess feasibility/acceptability and further refine the proposed set of items selected in phase 1 of the study. Phase 3. A multicentric prospective study to evaluate the validity, reliability and sensitivity to change of the CEGSSS. This research project is conducted by the Canadian Endourology Group (CEG), a panel of experts in the field of endourology in Canada. The CEG is a national member-based organization dedicated to enabling the profession to provide the highest possible standards of endourological care and to advance the science of endourology by collaboratively: 1. Fostering excellence in endourological practice through advocacy, education, research and practice support tools, 2. Leading evidence-based clinical practice through the development of practice standards and guidelines in endourology, 3. Providing continuous professional development for Canadian endourologists along the career-path continuum, 4. Providing leadership in public education for endourological conditions. Read Less

This is a prospective longitudinal study that will evaluate the unmet needs of older adults (65 and older) who return home (either directly or after short-term rehab) after an ICU hospitalization, evaluate the association of these unmet needs with clinically relevant outcomes, and assess barriers and facilitators to addressing these unmet needs. The proposed research will inform the development and evaluation of a subsequent intervention to improve functional outcomes among older ICU survivors, in alignment with the NIH's mission to reduce disability.

The Johns Hopkins Proton Therapy center is establishing a registry to capture the full 3D radiation dosimetry delivered to the patient, baseline clinical data, and disease, toxicity and quality of life outcomes. The goal is to have all patients treated at the proton center to be included in the registry to enable future comparisons of treatment outcomes to assist in understanding which patients can benefit from the use of protons.

The use of Cannabis is increasing in the population, and the effects that this might have on different medical procedures are poorly understood. Particularly when submitted to deep sedation or general anesthesia, there is no consensus on best drugs or doses to deliver. The purpose of this clinical trial is to clarify the influence of chronic cannabis use during office based general anesthesia for extraction of teeth. The procedures will be performed in the Oral and Maxillofacial Surgery Clinic at the College of Dentistry. Read Less

Prostate cancer is one of most common cancers in America, affecting 1 in 6 men. External beam radiation therapy is one of the common methods to treat prostate cancer. Although radiotherapy is effective, side effects to the adjacent normal organs limit the therapeutic ratio. Those side effects are usually associated with the radiation damage of the normal tissue surrounding prostate, e.g. bladder, urethra and rectum etc. Both effectiveness and the side effects of radiation treatment are often accessed after whole course of radiotherapy, which makes the early intervention difficult. The current research project is a feasibility study of utilizing advanced magnetic resonance imaging (MRI) techniques to access radiotherapy treatment response of prostate cancer during and right after radiotherapy. Many advanced MRI techniques, e.g. spectroscopy (MRS), diffusion-weighted (DWI), dynamic contrast enhanced (DCE) perfusion weighted images, have been used in radiology departments for diagnostic purpose. This research project is to study the feasibility of using advanced MRI sequences to monitor tissue response during and after radiotherapy. The tissue changes revealed from MRI can provide physicians early information on possible tumor recurrence and normal tissue toxicity, therefore, the early intervention may be possible to spare normal tissue and cure the patient. The project is designed to combine several different advanced MRI imaging techniques systematically to study tissue changes during radiotherapy, which has not been seen elsewhere to date. Another important goal of this research project is to study the feasibility of associating functional MRI with radiation treatment dose distribution. Tissue response during radiation treatment depends on dose. The functional MRI can provide more information than simple anatomic information. Mapping the functional MRI spatially and associating them with 3D dose distribution in radiation treatment planning system is one important step to quantitative assess the relationship between radiation treatment and tissue changes due to the radiation.
