A genetic variation in the gene for the protein dihydrofolate reductase (DHFR) that is necessary to utilize folic acid (a synthetic form of the B vitamin folate found in supplements and fortified food), increases the risk for breast cancer in multivitamin users and, when present in mothers who used folic acid supplements during pregnancy, increases the risk for cancer of the eye of their children. The aim of the proposed research is to understand how a common genetic variation ...
The purpose of this study is to evaluate the fetal biophysical profile (BPP) scoring in pregnant women from 20 weeks-0 days' to 36 weeks-6 days' gestation. A biophysical profile (BPP) is a score that is intended to assess fetal well-being. This test will be performed within the expected time of the routine ultrasound exam.
In this research project the investigators want to figure out whether ultrasound (a non-invasive method) can be used to assess how the fetus is doing during labor.
Study topic: Predicting fetal outcome using third trimester modified biophysical profile (BPP) scan compared with standard of care; a randomized clinical trial at St. Francis Hospital, Nsambya. This is an open label randomized clinical trial comparing the third trimester modified biophysical profile done between 34 to 40 weeks with the current standard of care in reducing perinatal mortality at St. Francis Hospital, Nsambya Objectives of the study: Broad study o...
To determine the biophysical impact of biophysical Impact of Transcutaneous Spinal Cord Stimulation (TSCS) within a single session. We hypothesize that subjects will demonstrate increased volitional muscle strength with TSCS. This will be assessed by isokinetic strength testing of post-injury dominant-side knee extension. Subjects will be tested in both Transcutaneous Spinal Cord Stimulation and sham conditions.
Effects of Smartphone Use at Night with Light Emitting Diode Display With and Without Blue Light in Healthy Adults: A Randomized, Double-blind, Cross-over, Placebo-controlled Comparison
It is well established that obese women are at an increased risk of stillbirth compared to non obese women. This has led many physicians to begin antenatal testing in obese women in the third trimester through either nonstress tests or biophysical profiles. However, there is little evidence that antenatal testing improves fetal outcomes in obese women. The aim of this study is to determine if antenatal testing improves outcomes in obese women and to determine the optimal mode o...
To assess the clinical utility of the graphical medication monitor, results of the anesthetics for which the display was present will be compared to the results of the anesthetics in which there was no display.
In this study, clinical variables related to eyelids that potentially have an effect on contact lens discomfort will be investigated such as eyelid signs and secretions, eyelid sensitivity, eyelid microbiome, Demodex infestation and tear film properties. The main aim of this study is to understand the duration of efficacy of debridement of the eyelid margin and its impact on various eyelid signs (such as lid wiper epitheliopathy, lid-parallel conjunctival folds, eyelid sensitiv...
A pilot study to determine the safety and efficacy of chimeric antigen receptor T cell (autologous T cells transduced with a lentiviral vector expressing chimeric antigen receptor) personalized immunotherapy for patients with recurrent malignant gliomas based on the expression of tumor specific/associated antigens (EGFRVIII, IL13Rα2, Her-2, EphA2, CD133, GD2).
Few studies have assessed the effects of Triphala and Rubia Cordifolia from a skin biophysical perspective. Here, we aim to understand how these herbs can modulate the skin's barrier properties and the gut microbiome.
This is a feasibility pilot study to introduce and evaluate an intervention designed to increase clinician awareness of their patients' urinary catheters, vascular catheters, and pressure injuries. This intervention, the "Patient Safety Display" will be evaluated in one hospital unit.
The investigator hypothesizes that regular consumption of almonds will 1) improve the facial wrinkle severity in post-menopausal women, 2) improve the evenness of facial skin pigmentation, 3) diversify the gut microbiome and increase the short chain fatty acids in the blood, and 4) improve the skin barrier biophysical properties.
The investigators' overarching goal is to investigate whether use of an augmented reality display system (utilized in addition to, not as a replacement to, conventional CT and MRI displays currently available in the procedure suite) streamlines the process of a procedure and/or provides ease of access to helpful pre-procedure and intra-procedure imaging information that would be more difficult and time-consuming to obtain with the conventional imaging display systems.
The goal of this study is to examine the ability of optical head‐mounted display technology to enlarge the visual field of patients with severe visual field loss due to retinal dystrophy and to improve mobility and patient‐reported outcomes.
In this study, test persons with chronic excessive UV radiation and a control group are examined by multiphoton laser imaging and biophysical methods in order to evaluate the dermal fiber network. We expect to observe signs of advanced skin aging in the test group.
Prospective, cross-sectional, observational study investigating a three dimensional heads up display for retinal surgery and comparing its outcomes and ease of use with the standard operative microscope.
Modern display technique seems to optimize visualization in minimal-invasive surgery. Many systems are available right now with a fundamental difference between the passive polarizing 3-dimensional (3D) and 2-dimensional (2D) technique. Data seems to show a benefit for the 3D technique in the visualization of the operative field. This could lead to more precision in minimal-invasive surgery. 2D-systems with high resolution of 4.096 x 2.180 pixels (4K) could be a promising alter...
An Advanced Virtual Exercise Environment Device (AVEED) has been developed that incorporates arm and leg ergometers in conjunction with a virtual reality interface. The purpose of this study is to examine participant perspectives regarding the virtual interface and exercise device combination with regard to usability, comfort, safety, rating of perceived exertion, and enjoyment.
RATIONALE: Monoclonal antibodies, such as anti-IL-6 chimeric monoclonal antibody, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. PURPOSE: This phase II trial is studying how well anti-IL-6 chimeric monoclonal antibody works in treating patients with metastatic prostate cancer that did not respond to hormone therapy.
The purpose of the study is to compare the changes in the appearance of dry skin after the use various moisturizers: white petrolatum ointment, coconut oil, jojoba oil, and almond oil in patients with dry skin.
The LOARAL project concerns patients who have undergone total knee arthroplasty to treat symptomatic osteoarthritis. Patient will be divided into two groups: a control group where patients will do standard rehabilitation and an experimental group where patients will do standard rehabilitation associated with the judgement of point-light display. The aim of this study is to validate the use of point-light display for the Rehabilitation of patients with a totalarthroplasty of the...
