Active clinical trials for "Disease Progression"

Prospective observational study with 7-year follow up. 55 patients are included with moderate to severe tooth wear, whereby through informed consent the decision was taking to monitor the patients. At the baseline and 1, 3 5, and the 7-year recall digital 3D scans will be made, which will be compared and subtracted.

Respiratory infections such as colds, flu and pneumonia affect millions of people around the world every year. Most cases are mild, but some people become very unwell. Influenza ('flu') is one of the most common causes of lung infection. Seasonal flu affects between 10% and 46% of the population each year and causes around 12 deaths in every 100,000 people infected. In addition, both influenza and coronaviruses have caused pandemics in recent years, leading to severe disease in many people. Although flu vaccines are available, these need to change every year to overcome rapid changes in the virus and are not completely protective. This study aims to find and develop predictive tests to better understand how and when flu-like illness progresses to more severe disease. This may help to decide which people need to be admitted to hospital, and how their treatment needs to be increased or decreased during infection. The aim is to recruit 100 patients admitted to hospital due to a respiratory infection. It is voluntary to take part and participants can choose to withdraw at any time. The study will involve some blood and nose samples. This will be done on Day 0, Day 2 and Discharge from hospital, and an out-patient follow-up visit on Day 28. The data will be used to develop novel diagnostic tools to assist in rational treatment decisions that will benefit both individual patients and resource allocation. It will also establish research preparedness for upcoming pandemics.

There is limited empirical data documenting disease progression and impact on quality of life for patients with X-linked hypophosphatemia (XLH). This study seeks to investigate the impact of XLH in adults living in the UK retrospectively and prospectively over a 12 month period, using qualitative interviews, SEIQoL-DW, EQ-5D-5L, SF36 quality of life tools. XLH is a rare, genetic, chronically debilitating and deforming condition (www.nice.org.uk/guidance/HST8). XLH is characterised by renal phosphate wasting, hypophosphatemia and defective bone mineralisation. The incidence of XLH is reported to be between 1:20,000 and 1:25,000 live births. In the UK, it is estimated that there are around 250 paediatric XLH patients and around 2,500 adult XLH patients (Delmestri,et al [Unpublished report]2018). The clinical phenotype of XLH is varied amongst patients, even among affected members of the same family. This can range from no signs or symptoms, slow growth in children, short stature, bone abnormalities that can affect movement and result in pain, bowed legs and knocked knees (where lower legs are positioned at an outward angle), tooth abscesses and excessive dental caries and hearing loss (adult patients only). This study will recruit 36 adults living with XLH, who are aged 28 years or over and living in the UK. The study will be advertised by the Sponsor and funder Medialis Ltd and via the patient organisation Metabolic Support UK. All study activities will take place via tele-visits and online questionnaires. The study will last approximately 2 years, allowing for one-year recruitment and a further 12 months to conduct all study visits.

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.

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.

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 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.

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.

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.
