Real-World Study of Post-Resistance Treatment Strategies in Advanced Breast Cancer Following CDK4/6i, PIK3CA Inhibitors, or T-DXd
This is a real-world observational study aiming to evaluate the effectiveness of post-progression treatment strategies in patients with advanced breast cancer who have developed resistance to prior targeted therapies, including CDK4/6 inhibitors, PIK3CA inhibitors, trastuzumab deruxtecan (T-DXd), or other targeted agents commonly used in clinical practice. As resistance to these …
Exosomes in Rectal Cancer
The primary aims of this study is to characterize exosomal biomarker levels in patients with locally advanced rectal cancer undergoing neoadjuvant chemoradiation therapy. Compare rates of exosomal expression before during and after chemoradiation therapy with pathologic response rates at the time of APR or LAR. The researchers will also examine …
Natural History Study of GEMIN-5 Related Neurodevelopmental Disorder
This study will include a comprehensive retrospective chart review and a longitudinal prospective observational natural history study to characterize the phenotypic spectrum of GEMIN5-Related Neurodevelopmental Disorder. We aim to define the trajectory of this ultra-rare disease, core clinical features, characteristics at disease onset and diagnosis, neurological symptomatology, and neuroimaging findings …
Primary and Secondary Stability of a One-Piece Compressive Implant System
Implant stability plays a major role in establishing implant osseointegration; it is considered an important requirement to decide the functional loading time with a fixed prosthesis. Objectives: to investigate the influence of one-piece implant position on their primary and secondary stability. The implant gains its Primary stability at placement time …
Increasing Pre-Surgical Identification of Muscle Invasive Tumor Evaluations Prior to Planned Cystectomy (INSITE)
This trial aims at investigating the diagnostic ability of a combined diagnostic panel including systematic endoscopic evaluation (SEE), blood-based ctDNA assay, and urine-based cfDNA assay to predict the presence of residual tumor remaining in the bladder at cystectomy. Patients who are planned for cystectomy due to bladder cancer will be …
Use of Novel Plasma and Urinary Biomarkers to Predict the Development of Hepatorenal Syndrome in Cirrhotic Patients
This study investigated the use of novel plasma and urinary biomarkers to predicte the development of hepatorenal syndrome in patients with advanced cirrhosis. The biomarkers investigated include plasma cystatin C, plasma NGAL, plasma NAG, plasma IL-18, plasma ADMA, plasma BTP, urinary KIM-1 and urinary LFABP. These biomarkers will be checked …
Molecular Analysis of Suspected or High-Risk Lung Cancer to Drive Individualized Care (Interception for Suspected Lung Cancer)
This study evaluates the effectiveness of robotic biopsies in providing information about hereditary or cancer specific genetic variants that may have a role in diagnosis of cancer and to develop genetic results and medical record databank for future studies.
Examination of the Large Intestine With Camera Capsule in Patients With Blood Stream Infection With Gut-associated Bacteria
The goal of this observational study is to diagnose colorectal cancer or precancerous tumors in participants over the age of 18 hospitalized with blood stream infection with anaerobic gut-associated bacteria. The main question it aims to answer is: • How prevalent is cancer and precancerous tumors in the large intestines …
Prevalence av BPPV Among Elderly in Primary Care
This study aims to investigate whether positional tests should be routinely performed on all elderly patients (65 years and older) presenting to primary care with symptoms of acute, episodic, or chronic dizziness or vertigo, unsteadiness, imbalance, and/or an increased tendency to fall in the past 12 months. Study aims to …
Natural History of Depression, Bipolar Disorder and Suicide Risk
Mood disorders, such as depression and bipolar disorder, are difficult to treat. One reason is that there are no objective ways to measure how these disorders affect the body and respond to different treatments. In this study, researchers want to perform tests on people undergoing clinical care for mood disorders. …
