Filter by:The world is currently facing a pandemic with the coronavirus (SARS-CoV-2) which leads to the disease of COVID-19. Risk factors for a poor outcome of COVID-19 have so far been identified as older age and co-morbidity including chronic respiratory conditions such as chronic obstructive pulmonary disease (COPD) and current smoking status. Previous studies found, that vitamin D deficiency is more prevalent among patients with these risk factors. There are observational studies reporting independent associations between low serum concentrations of 25-hydroxyvitamin D (the major circulating vitamin D metabolite) and susceptibility to acute respiratory tract infection. Vitamin D substitution in patients with COVID-19 who show a vitamin D deficiency should therefore be investigated for efficacy and safety. The study is designed as a randomized, placebo-controlled, double blind study. The objective of the study is to test the hypothesis that patients with vitamin D deficiency suffering from COVID-19 treated under standardized conditions in hospital will recover faster when additionally treated with a single high dose of vitamin D compared to standard treatment only.
While many people with COVID-19 suffer from respiratory disease, there is growing evidence that the virus also affects other organs. The purpose of this study is to better understand the effects of COVID-19 on the lungs and other organs. The study investigators have developed new techniques in Magnetic Resonance Imaging (MRI) to scan the lungs, heart, brain and liver. The study investigators hope to learn more about how the virus causes inflammation in these organs and how this inflammation changes over time as people recover from COVID-19 illness. The study aims to enroll 228 people in Alberta. Participants will undergo one or more MRI scans and have blood testing at one or more time points to assess for inflammation, kidney function, liver function and possible heart injury. Participants will also undergo testing to assess sense of smell, cognition (thinking and memory), spirometry (breathing test for lung function) and and exercise tolerance (walk test). The study investigators hope this study will help us learn more about the long-term risks of COVID-19 disease.
A novel coronavirus, designated corona virus disease 2019 (COVID-19) has resulted in a Pandemic at the time of writing (27th April) the reported number of confirmed cases exceeding 3 million and over 200000 associated deaths. The burden on global critical care has been considerable. As of 24th April there have been 8752 UK critical care admissions with services under considerable strain, and a mortality rate over 50%. Survivors of critical illness will require significant input. This study will perform mixed methods to provide rich data on risk stratification and recovery from critical illness. Recovery from a novel disease requires documenting and the study reports physical and psychological changes following hospital discharge in survivors. In addition qualitative interviews are being conducted with patients who have survived and been discharged from critical care along with their relatives and treating professionals, to better understand their needs during recovery.
This study involves evaluating pediatric patients with central lines to determine differences in line complications and quality of life in those with a novel central line securement device (wrap) as compared to those who use a traditional securement device (dressing).
In patients with SARS-CoV-2 or bacterial infection admitted to the intensive care unit (ICU), the state of the intravascular volume, the characteristics of the blood volume components, and the development of a vascular leak is currently unknown. The relationship of these parameters with parameters of cardiac performance, lung edema and sublingual microcirculatory perfusion parameters have never been studied.
Severe pneumoniae related to Coronavirus Disease (COVID-19), had a high in-hospital mortality; this condition are worst in subjects with acute kidney disease (AKI); conditioning increased mortality, days of assisted mechanical ventilation (AMV), increased nosocomial infections and high costs. We need many studies for determinated the risk factors for AKI in subjects with COVID-19. This study pretends identify the incidence of AKI in subjects with severe pneumoniae by COVID-19, describe the role of some biomarkers in the physiopathology of AKI-COVID-19; and determine the evolution of urinary biomarkers during hospitalization, like neutrophil gelatinase-associated lipocalin (NGAL), tissue inhibitor of metalloproteinases-2 (TIMP-2), insulin-like growth factor binding protein-7 (IGFBP7), and interleukin-6 (IL-6) and the progression of viruria of Severe Acute Respiratory Syndrome (SARS) related to CoronaVirus 2 (CoV2) in subjects with or without AKI.
There is emerging evidence that patients with SARS-CoV-2 are affected by increased coagulopathy, including in the most advanced forms, a fully blown disseminated intravascular coagulation, leading to multi organ failure (MOF). Post-Morten observations from patients who died because of SARS-CoV-2 infection in Bergamo, Italy and other places have revealed the presence of diffuse venous, arterial and microcirculatorythrombosis, not only restricted to the lung but also involving the kidneys, heart and gut. Thrombin plays a central role in mediating clot forming as well as in mediating inflammation. A direct factor X inhibitor, namely edoxaban can act as prophylactic measure to mitigate the risk of venous and arterial thrombotic complications. Colchicine is an inexpensive (generic drug), orally administered, and a potent anti-inflammatory medication. It might accelerate SARS-CoV-2 clearance. The aim of the CONVINCE study is therefore to assess the safety and efficacy of edoxaban and/or colchicine administration in SARS-CoV-2 infected patients who are managed outside the hospital with respect to the occurrence of fatalities, hospitalisation, major vascular thrombotic events or the SARS-CoV-2 clearance rate under RT PCR.
The aim of this diagnostic accuracy study is to develop a clinical prediction rule based on signs, symptoms, patient characteristics and blood tests, to be used in ambulatory care to help physicians safely rule out a serious infection in an older patient. It will be performed in general practices and emergency care departments across Flanders (Belgium).
This phase I trial investigates the side effects of cabozantinib and nivolumab in treating patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and who are undergoing treatment for human immunodeficiency virus (HIV). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib and nivolumab may shrink or stabilize cancer in patients undergoing treatment for HIV.
The disease leishmaniasis mainly occurs in hot and tropical countries, affects millions of people and causes around 20,000 deaths across the world every year. Leishmaniasis is caused by the Leishmania parasite and is transmitted by sand flies. The parasite is tiny and not visible to the naked eye, whereas the sand fly is visible but small and inconspicuous. There are different types of leishmaniasis which can affect the skin (cutaneous leishmaniasis) or the internal organs of the body (visceral leishmaniasis). Some of the milder forms will produce skin problems which will be localised, whilst other forms of leishmaniasis will cause widespread skin changes. The skin lesions of cutaneous leishmaniasis can be disfiguring if left untreated. There are some treatments for leishmaniasis but many of them are not easy to use or don't work well. Therefore, new treatments are needed including vaccines that prevent or work against leishmaniasis. A solution being adopted for other diseases, which the investigators now wish to adopt for leishmaniasis is to develop a 'Controlled human infection model' (CHIM). These models involve deliberate exposure of individuals to an infection, in order to better understand how the disease works and to test potential vaccines and treatments. They have contributed knowledge that has led to advances in the development of treatments. This is study builds on an our initial successful study, FLYBITE, where uninfected (disease-free) sand flies were used to test the safety aspects and ensure that sand flies were able to bite human participants in a controlled environment. The investigators observed no major adverse effects and it was well tolerated by participants. The investigators therefore wish to proceed to a study using sand flies infected with a form of leishmaniasis that causes localised skin disease and is treatable, on the pathway to assessing future vaccines.
