Active clinical trials for "Disease Progression"

What Comes After Fulvestrant? A Real World Multicenter Retrospective Study-Treatment After Progression of Fulvestrant Among Metastatic Breast Cancer Patients in China.

Focal segmental glomerulosclerosis (FSGS) is one of the most common primary glomerular diseases leading to end stage renal disease. In this study, our aim is to evaluate the effects of histopathological, clinical, and laboratory features of patients with primary FSGS on the disease progression.

The study is designed as a retrospective analysis of patients with relapsed/refractory FL identified by the hematological centers of Italy.

Knowledge of the natural history and progression of macular holes is mainly limited to the studies from the pre-optical coherence tomography era. By observing macular holes preoperatively we are able to determine the extent of the preoperative macular hole progression. At our institution macular holes are treated in an elective setting. The majority of macular holes undergo a 2-step sequence of phacoemulsification and intraocular lens implantation followed by vitrectomy. We wish to observe the effect of time and cataract surgery on the progression of macular holes prior to vitrectomy.

To investigate the role of initial venous lactate in predicting the severity progression to overt septic shock and 30-day mortality in non-elderly patients without hemodynamic shock who suspected to have acute infections.

Heart failure is the most costly diagnosis in the Medicare population. Clinical depression is strikingly common in heart failure patients, and not only diminishes their quality of life, but also is associated with a markedly increased risk of hospitalization or death. This study is designed to further our understanding of the behavioral and biological effects of depression in patients with heart failure, so that appropriate treatments can be developed.

This non-drug, single center, 24-week, longitudinal study in ambulant spinal muscular atrophy (SMA) patients and in age- and gender-matched healthy volunteers will assess the detection of disease progression by magnetic resonance imaging (MRI) and the Muscle Function Measure (MFM) test. Each participant will be evaluated in three testing sessions: at baseline, at Week 12 and at Week 24. Both patients and volunteers will undergo MRI scans. Patients will additionally undergo testing of motor function and have blood samples taken for Survival of the Motor Neuron (SMN) genes, proteins and mRNA analysis.

The need for new technologies and devices in the field of neurosurgery is well established. In April 2013, FDA cleared NeuroBlate™ System, minimally invasive robotic laser thermotherapy tool. It employs a pulsed surgical laser to deliver targeted energy to abnormal brain tissue caused by tumors and lesions. This post-marketing, multi-center study will include patients with metastatic tumors who failed stereotactic radiosurgery and are already scheduled for NeuroBlate procedure. The study will collect clinical outcome, Quality of Life (QoL) and, where feasible, healthcare utilization data for publication.

This study will assess safety and ergonomics/engineering design of a novel cancer treatment, Continuous Low Irradiance Photodynamic therapy (CLIPT). We will assess the effects on primary and metastatic tumors involving the skin, in particular to improve the functionality, efficiency and wearability of the light delivery device (LDD) as well as the overall treatment in subjects with chest wall recurrences of breast cancer. An ongoing study (IRB# 8227), sponsored by a Susan G. Komen Breast Cancer Foundation grant, using a 1st generation LDD device has evaluated and determined a dose-limiting toxicity of CLIPT for subjects with chest wall recurrences of breast cancer. A Diomed laser will be the device used in this study. The Diomed laser will deliver 630 nm (red spectrum) light through a Fiber Optic Patch. The Fiber Optic patch will be compatible with the laser, delivering light to a designated region on the patient's skin.

In many areas of the world most severely affected by the HIV/AIDS pandemic, insect and water-borne diseases such as malaria and diarrheal disease are common causes of illness and death. In addition, diarrhea and malaria are more common and more severe among adults and children infected with HIV. These infections may modulate the immune system, affect the replication of the HIV virus and could result in more rapid HIV disease progression in co-infected individuals. Access to practical, inexpensive and easy to use interventions to prevent these diseases may be effective in delaying HIV progression. Current Kenya government and World Health Organization guidelines recommend the use of cotrimoxazole (trimethoprim-sulfamethoxazole [TMP/SMX]) to prevent co-infections, including malaria. Despite the provision of TMP/SMX to HIV-infected adults, infections with malaria and pathogens causing diarrhea remain common causes of morbidity and mortality in many resource-limited settings. In addition, TMP/SMX may not prevent all infections with malaria or other pathogens due to alternative mechanisms of action, antimicrobial resistance and non-compliance due to adverse events or other reasons. We propose a study to evaluate the impact of providing insecticide treated bednets and a simple water filtration device on markers of HIV disease progression among a cohort of ART naïve, HIV infected adults prescribed TMP/SMX in Kenya. In addition, we propose to evaluate the effect of these interventions on malaria and diarrheal disease incidence and on compliance with TMP/SMX.
