Filter by:The study use UK based linked electronic health records from the Clinical Research Datalink (CALIBER) of 5.6 million individuals to conduct a matched case-control study to investigate the incidence of influenza in individuals prescribed ACEI compared to those not prescribed ACEI.
Investigational medications adjunct to clinical standard of care treatment will be assessed to evaluate safety and effectiveness as an anti-COVID-19 treatment. All hospitalized persons with moderate to severe COVID-19 disease that meet eligibility criteria will be offered participation.
Infection with SARS-CoV-2 or severe acute respiratory syndrome coronarvirus type 2 was highlighted in December 2019 in the city of Wuhan in China, responsible for an pandemic evolution since March 11, 2020. The infection affects all ages of life, although affecting children in a very small proportion of cases. The typical presentation of the disease combines fever (98%), cough (76%), myalgia and asthenia (18%) as well as leukopenia (25%) and lymphopenia (63%). Upper airway involvement rare. The main clinical presentation requiring hospitalization of infected patients is that of atypical pneumonia which may require critical care management (27%), and progress to an acute respiratory distress syndrome (67%) involving life-threatening conditions in almost 25% of patients diagnosed with SARS-CoV-2 infection. Other organ damage have been reported, mainly concerning kidney damage (29%) which may require renal replacement therapy in approximately 17% of patients. Neurological damage has been very rarely studied, yet reported in 36% of cases in a study including patients of varying severity. Finally, the mortality associated with this emerging virus is high in patients for whom critical care management is necessary, reported in 62% of patients. We therefore propose a prospective observational study which aim at reporting the prevalence of acute encephalopathy at initial management in Critical/Intensive care or Neurocritical care , to report its morbidity and mortality and to identify prognostic factors.
This study project includes a single-arm phase 2 study and a parallel cohort study, enrolling patients with COVID-19 pneumonia.
The scientific community is in search for novel therapies that can help to face the ongoing epidemics of novel Coronavirus (SARS-Cov-2) originated in China in December 2019. At present, there are no proven interventions to prevent progression of the disease. Some preliminary data on SARS pneumonia suggest that inhaled Nitric Oxide (NO) could have beneficial effects on SARS-CoV-2 due to the genomic similarities between this two coronaviruses. In this study we will test whether inhaled NO therapy prevents progression in patients with mild to moderate COVID-19 disease.
Knowing the dramatic increase in thrombin generation during sepsis, our research hypothesis is that AMPK-induced ACC phosphorylation in platelets is increased and that this might modulate platelets metabolism and more particularly platelets inflammatory mediators content, coming from AA and lipids.
This is a pilot study to assess the feasibility of establishing a national sero-epidemiological survey in England in individuals aged 0-24 years, focusing on assessing humoral immunity against diphtheria, Group C invasive meningococcus and SARS-CoV-2. The investigators will recruit 2800 to 3800 individuals, divided into three groups: Group one (N= 2300): This will include all age groups (0-24years), with recruitment restricted by postcodes provided by Public Health England (PHE) to recruit a representative population for the region as assessed by the IMD (Index of Multiple Deprivation scores). Group two (N= up to 1200): This group has been added following additional funding to enhance the sample size in response to the COVID-19 pandemic. This will recruit 0-19 year olds and will not be restricted by post code sampling. Instead recruitment will be by public promotion within the normal recruiting regions for each site. Group three (N= up to 300): Addition of Group 3 which is enhanced surveillance in participants from Black, Asian or minority ethnic groups (BAME). Since the start of recruitment we have noted that only 11% of participants are from BAME population, despite recruiting in ethnically diverse regions. Given the increased risk of COVID-19 disease in the BAME community, this is a potential limitation of the study as it stands, not only because it may not reflect the diversity of the UK population, but because it does not allow assessment of whether the differing disease rates and seropositivity in adults are reflected in differences in seropositivity rates in children. Similarly to Group 2, this will recruit 0-19 year olds and will not be restricted by post code sampling.
After a 30-year decline, heart disease is projected to increase up to 18% by 2030. Participation rates in cardiac rehabilitation remain extremely low and hopeless individuals are less likely to participate. This innovative study has the potential to advance science, improve patient care, and improve patient outcomes by demonstrating the effectiveness of the Heart Up! program to increase physical activity and reduce hopelessness in patients with heart disease. Hopelessness is associated with a 3.4 times increased risk of mortality or nonfatal myocardial infarction in patients with ischemic heart disease (IHD), independent of depression. Hopelessness has been identified in 27-52% of patients with IHD and can persist for up to 12 months after hospital discharge. Hopelessness, a negative outlook and sense of helplessness toward the future, can be a temporary response to an event (state) or a habitual outlook (trait). Hopelessness is associated with decreased physical functioning and lower physical activity (PA) levels in individuals with IHD. While research has investigated strategies to increase PA among IHD patients in general, the study team is the only group to design an intervention to promote PA specifically in hopeless IHD patients. The purpose of this randomized controlled trial is to establish the effectiveness of our 6-week mHealth intervention (Heart Up!) to promote increased PA in hopeless patients with IHD. A total of 225 hopeless IHD patients will be enrolled from a large community teaching hospital in the Midwest. Patients will be randomized (75 per group) to one of three groups: 1) motivational social support (MSS) from a nurse, 2) MSS from a nurse with additional significant other support (SOS), or 3) attention control (AC). It is hypothesized that 1) The MSS with SOS group will have the greatest increase in average minutes of moderate to vigorous PA per day at 8 and 24 weeks as compared to the MSS only or AC groups; 2) Greater increase in minutes of moderate to vigorous PA per day will be associated with decreased state hopelessness levels from baseline to weeks 8 and 24; and 3) Increased social support and increased motivation will mediate the effects of Heart Up! on a greater increase in moderate to vigorous PA at 8 and 24 weeks. The findings from this study could transform care for IHD patients who are hopeless by promoting self-management of important PA goals that can contribute to better health outcomes.
Conducting an initial small, controlled clinical pharmacology trial to assess for therapeutic biologics activity (proof-of-concept) that suggests the potential for clinical benefit of COVID-19 patients. 1. Treat Infection of Multiple Gene Mutation COVID-19 Virus Strains. 2. Activate Human Antigen Presentation Reaction to COVID-19 Specific Antigen. 3. The human antigen presenting cells (APCs) can take up and process COVID-19 target antigen protein into small peptide fragments, and then COVID-19 virus can be killed by APCs directly.
The purpose of this study is to see if repeat bacillus Calmette-Guérin (BCG) vaccinations can confer a beneficial immune and metabolic effect on Type 1 diabetes. Published Phase I data on repeat BCG vaccinations in long term diabetics showed specific death of some of the disease causing bad white blood cells and also showed a short and small pancreas effect of restored insulin secretion. In this Phase II study, the investigators will attempt to vaccinate more frequently to see if these desirable effects can be more sustained. Eligible volunteers will either be vaccinated with BCG in a repeat fashion over a period of four years, or receive a placebo treatment. The investigators hypothesize that each BCG vaccination will eliminate more and more of the disease causing white blood cells that could offer relief to the pancreas for increased survival and restoration of insulin secretion from the pancreas. An additional adaptive trial for COVID-19 is also being conducted on these randomized double blinded type 1 diabetic subjects receiving BCG or placebo injections. An expanded study arm has been approved for repeat dosing of BCG in adult Type I diabetes.
