Filter by:The purpose of this study is to identify behaviours and experiences of communities healthcare professionals (doctors, nurses and physiotherapists) in the management of the SARS-CoV 2 epidemic by identifying the impact of the epidemic on their work, their personal life and the difficulties they had experienced.
Our understanding of the clinical manifestations of COVID-19 is growing on a daily basis and there is evidence that increased age, cardiovascular risk factors and cardiac comorbidity are strongly associated with poor outcomes. Furthermore, myocardial injury occurs and is associated with a much worse outcome and rapid increase in mortality. There have been several reports of myocarditis and heart failure following infection. The mechanisms of myocardial injury and its consequences are not well understood. In an ongoing peer-reviewed and funded study, the investigators are evaluating the use of magnetic resonance imaging (MRI) to characterise and to understand the mechanisms of heart failure and myocarditis. Following strong encouragement by the British Heart Foundation, the investigators now propose to extend this investigation to patients who have recovered from COVID-19 infection to understand the mechanisms of myocardial injury that they have experienced. Using gadolinium and manganese-enhanced MRI combined with Computed tomography coronary angiography (CTCA), the investigators will assess the mechanisms and direct impact of myocardial injury in patients who have recovered from COVID-19 infection. This will help the investigators understand how best to manage individuals who demonstrate evidence of myocardial injury and potentially provide insights that could lead to novel treatment interventions to reduce such injury and improve patient outcomes.
The 2019 coronavirus-induced infection (COVID-19) has caused a pandemic that has spread worldwide. Up to date, many subjects affected by the virus report important sequelae on different organs increasing morbidity and exacerbating previous pathological conditions. Mortality is also increased in cases of comorbidities such as cardiovascular disease, hypertension and diabetes. COVID-19 infection is caused by Coronavirus-2 (SARS-CoV-2). Concerning the specific interaction of SARS-CoV-2 with the cardiovascular system, we know that this virus enters the body through the receptors for the conversion of angiotensin II (ACE2r) that are present in the lungs, heart, intestinal epithelium and vascular endothelium. This receptor's availability suggests a multi-organ involvement with a consequent multi-organ dysfunction, as found in patients affected by SARS-CoV-2 infection. Furthermore, poor vascular peripheral function -usually correlated with old age and long periods of bed rest or hypomobility- is a distinguishing characteristic of the population affected by COVID-19, as well. Thus, it is reasonable to expect that peripheral vascular function, already deteriorated by aging and common age-related diseases, can be further compromised by COVID-19 and by the forced hypomobility, typically experienced during the acute phase of the disease. The main aim of this project will be to investigate the peripheral NO-mediated vascular function in the leg of patients recovering from Covid-19 pneumonia. A significant vascular dysfunction is expected to be found in post COVID individuals and to be correlated to the relevant clinical variables.
This is a randomized, double-blind, placebo-controlled, Pilot, Phase 2 Exploratory study that will enroll subjects with a clinical diagnosis of COVID-19 confirmed by laboratory testing and who are in severe or critical condition as indicated by life-support measures.
The rationale in severe COVID19 infection is to undertake PEX to aid reduction of the hyperinflammation and reduce the morbidity and mortality to the lungs, but also systemically, such as the heart, kidneys and brain. A feasibility study of PEX therapy has been undertaken and confirmed a reduction in the inflammatory markers, no VTE/arterial events and normalisation of the renal function and cardiac function throughout the period of therapy. As plasma exchange is an intensive treatment modality, blocks of 5 daily PEX will be undertaken. Further blocks of PEX treatment can be initiated as dictated by the clinical and laboratory parameters. Unlike many therapeutic schedules, there is no immunosuppression associated with PEX; indeed, the resulting decrease in inflammatory markers were shown to be associated with an increase and sustained lymphocytes count.
The respiratory distress that goes with COVID-19 infection has been related to a procoagulant state, with thrombosis at both venous and arterial levels, that determines hypoxia and tissue dysfunction at several organs. The main sign of this thrombotic activity seems to be the D-Dimers, that have been proposed to identify patients with poor prognosis at an early stage. Knowledge on how to prevent or even treat this procoagulant state is scarce. COVID-19 patients may be out of general thromboprophylaxis recommendations, and recent studies suggest a better prognosis in severe COVID-19 patients receiving anticoagulant therapy with low molecular weight heparin (LMWH). However, the LMWH efficacy and safety, mainly in patients admitted to an Intensive Care Unit, remains to be validated.
Prospective, observational, exploratory study exploring the relationship between passively-collected data from wearable activity devices and SARS-CoV-2 infection
The primary objective of this study is to evaluate the efficacy of CKD-314 (Nafabelltan) compared to standard of care (SOC), with respect to clinical status assessed by a 7-point ordinal scale in hospitalized adult patients diagnosed with COVID-19 pneumonia
The current study was conducted at Qena Governorate, Egypt, during the period from May 2020, to July 2020. The study included 305 COVID-19 cases diagnosed by PCR, patients were randomly assigned to one of three study limps, Azithromycin 500 mg/24 h for 7 days, Clarithromycin 500 /12 h for 7 days, or a control group with no antibiotics, All three groups received only symptomatic treatment for control of fever and cough
The COVID-19 pandemic is considered as the most crucial global health concern of the century. Given the complex interaction of physical and social factors on fast spreading infection, there have been increasing calls for comprehensive efforts using a community-based participatory research (CBPR) approach. CBPR partnership composed of representatives from community-based organisations, health and academia actively developed the present study. Specific aims were (1) to assess the efficacy and safety of Ayurvedic combination, Giloy (Tinospora Cordifolia) and Pippali (Piper longum) in the management of mild-to-moderate cases of COVID-19 and (2) to determine the effect in relieving COVID-19 symptoms and preventing the onset of severe infection.
