Filter by:Coronavirus-induced disease 2019 (COVID-19) is an infection caused by a virus whose full name is severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This is a new and rapidly-spreading infectious disease which carries a significant risk of death, has brought massive economic impact globally and has proved hard to contain through public health measures. While we currently have effective vaccines, they do not protect the whole community and the constant threat of new mutations means there is an urgent need to identify new approaches to reducing community spread of infection. Heparin is a naturally occurring sugar molecule which has been used for a century to treat a range of medical problems including heart attacks, strokes, and blood clots. It has also been investigated as a treatment for pneumonias. Recent research suggests it binds to the SARS-CoV-2 virus in such a way it may reduce the virus' ability to enter cells. This may be an important way to tackle the early stages of infection which occurs inside the nose. Therefore, this medication could be used amongst people with early COVID-19 infection and amongst their household contacts to reduce the rate of virus transmission during local outbreaks. If proven effective there are many other potential uses as primary prophylaxis for people working in high risk areas, for travel, for protection in high risk crowded environments such as nightclubs, or sporting events. Heparin is safe, inexpensive, available worldwide and if effective could be rapidly used across the world to slow progression of the current pandemic. Further there are recent studies suggesting that the risk of brain complications as part of "long COVID", are directly related to the amount of virus in the nose. Reducing the viral load in the nose is thought to be effective in reducing these "long COVID" complications. This study will explore the effect of the intervention on viral load and long COVID. In this study, researchers want to investigate this medicine in people who have been identified by a COVID-19 swab test to be in the early stages of infection(defined as the index case), and amongst their household contacts. Each participant would take the medicine or a dummy control solution by spray into their nose three times a day for 10 days. The study will investigate if there are fewer people who contract SARS-CoV-2 infection by day 10 amongst households who receive the medicine than households which receive the dummy control.
Thoracic complications directly or indirectly consequence of Coronavirus Disease 2019 (COVID-19) (including either pathologies strictly related to the infection, or iatrogenic effects of therapeutic attempts to treat it) have been described during the pandemic. Many of the above conditions often require a surgical approach but, based on published data reporting high early postoperative morbidity and mortality, many experts initially advised against any referral to surgery in COVID-19 patients. Therefore, the issue is if salvage surgical approach should be always excluded or could be considered when it represents the only remaining effective option. In the absence of solid data and recommendations, this is a demanding challenge for thoracic surgeons. The investigators have coordinated a multicenter study to collect the experience of several worldwide high-volume thoracic surgery departments. Their objective is to investigate efficacy and safety of surgery in COVID-19 patients who developed thoracic complications that required operative management.
The current COVID-19 pandemic is the most severe health crisis of the 21st century. This is not only due to the deaths caused by the disease. People that were affected by COVID-19 and supposedly recovered may suffer from long lasting sequelae. The presence of symptoms longer than 3 months after the infection with SARS-CoV-2 is referred to as Post-COVID-19 Syndrome or Long COVID-19. It is estimated that 10-20 percent of all infected people are affected. The most common symptoms include persistent fatigue, reduced physical capacity, dyspnoea, ageusia, anosmia, musculoskeletal pain and neuropsychological complaints such as depression, anxiety, insomnia and a loss of concentration. Considering the novelty of the pathology, evidence on the successful treatment of Post-COVID/Long-COVID is scarce. Physical activity has been established as a treatment option for chronic diseases that have similar symptomatic manifestations to those of Post-COVID/Long-COVID. For example, exercise therapy has shown positive effects on the health status of patients with lung disease, depression, anxiety, insomnia and cognitive impairment. However, there has been controversy whether so-called Graded Exercise Therapy (GET) is a safe treatment strategy for patients with Chronic Fatigue Syndrome (CFS). This population may experience Post Exertional Malaise (PEM), a worsening of symptoms after physical, cognitive or emotional exertion. Since COVID-19 might be an infectious trigger for CFS, particular caution has to be taken when recruiting participants and when screening them for adverse events and worsening of symptoms during an exercise intervention. It can be hypothesized that patients suffering from Post-COVID/Long-COVID can benefit from exercise in various ways, guaranteed that there is sufficient screening for PEM before and during the intervention and training volume and intensity are increased slowly and progressively. The current study investigates the effects of two different training modalities, endurance training and a combination of endurance training and resistance training, on various parameters in people affected by Post-COVID/Long-COVID.
Patients infected with covid-19 have a series of clinical manifestations, including fever, cough, myalgia or fatigue, dyspnea, even acute respiratory distress syndrome (ARDS), acute cardiac injury and secondary infection, and a lot of sever patients had to been admitted to the intensive care unit (ICU) One of the hallmark of COVID 19 is the cytokine storm that provokes primarily pneumonia followed by systemic inflammation. besides the positive viral nucleic acid analysis and the representative pulmonary CT findings (bilateral distribution of patchy shadows and ground glass opacity), most individual patients showed the changes in several immunological and biological markers . CD177 which is one of the most clinically important neutrophil alloantigen because: i) it is a neutrophil-specific marker representative of neutrophil activation, ii) it was the most highly differentiated expressed gene in patients, and iii) the protein can be measured in the serum, making its use as a marker clinically applicable. It is expressed on neutrophils, neutrophilic metamyelocytes, and myelocytes . Given the contribution of the neutrophil activation pathway in the clustering of COVID-19 patients, neutrophil-activation features that could act as possible reliable markers of disease evolution.
The purpose of the pilot study is to examine acceptability and proof of concept effectiveness of a wireless TENS technology to address PACS associated FM. Sample size (n=40) is convenient and designed to explore acceptability and feasibility. Eligible participants will be screened at the BCM Post-COVID-19 Clinic for inclusion criteria. Participants, who satisfy the inclusion and exclusion criteria and sign the informed consent form will be randomly assigned with ratio of 1:1 into two groups. One group will utilize TENS functional devices (Active group, AG); the other group will utilize TENS non-functional devices (Placebo group, PG). The baseline measurements will be performed, and the patients will take the programmed device home for a duration of 4 weeks. Then, the patients will come back after four weeks (4W). At this 4th week visit, both groups will be unblinded and the AG will keep their functional device and the PG group will receive a functional device. Both groups will continue to deliver 3-5 hour of stimulation daily, until their final 8th week follow up visit (8W). The primary outcomes will be pain symptoms, sleep and fatigue. Secondary outcomes include limb strength and perfusion, gait assessment (gait speed, stride length, double stance, and gait steadiness), balance, pulse oximetry, and quality of life. The coordinator will utilize a weekly spreadsheet showing utilization (therapy sessions/day, logged in the Quell health Cloud) so compliance can be monitored and those that are not using the device can be encouraged.
Severe and sometimes irreversible sequelae are observed in people who have developed a severe form of COVID-19 (pulmonary, cardiovascular, renal, neurological sequelae among others). More than 10% of individuals who contracted the disease, even in a mild form, still have at least one of the initial symptoms at six months, also known as prolonged symptoms or long COVID syndrome. The most frequently observed symptoms are asthenia, neurological disorders (headache, anosmia, ageusia, etc.), cardio-thoracic disorders, pain, digestive or skin disorders. Very recently, the first results of a British prospective cohort study (PHOSPCovid) indicate that more than half of the COVID-19 survivors who were hospitalised experienced a very severe to moderate deterioration in their mental and/or physical health five months after hospitalisation. Women are particularly affected. Another American study shows that 85% of non-hospitalised COVID-19 patients developed at least 4 neurological symptoms impacting their quality of life. The most common are: "brain fog" (81%), headaches (68%), numbness or tingling (60%), taste impairment (59%) and loss of smell (55%). These disabling symptoms may persist for weeks or months, deteriorating the quality of life of patients and making it difficult for some to return to a normal life. On the basis of current knowledge concerning the long-term sequelae of SARS-CoV-2 infection, it seems necessary to offer these subjects a specific care pathway and to adapt their living and working conditions beyond their medical care. The present study is aimed at measuring the impact of long COVID on the health and quality of life of the defence community (military personnel and their families).
All surviving patients of the Michigan Medicine COVID-19 Cohort (M2C2, PI: Hayek) that were admitted to the University of Michigan for severe COVID-19 disease are eligible for this study. Investigators had prior approval from the Institutional Review Board (IRB) to collect the baseline blood and urine samples of these participants. Initial analysis on those samples are ongoing. In preliminary analysis of these patients a significantly higher risk for severe acute complications in patients with diabetes compared to those without diabetes was observed. The study will also enroll people following documented COVID-19 infection, regardless of whether or not they were hospitalized. The goal of the study is to understand what drives the increased risk of severe acute COVID-19 complications as well as to understand the long term sequelae of COVID-19 infection in patients with diabetes. The objectives of this study are to invite surviving M2C2 participants as well as others who have survived COVID-19 infection for an in-person visit, to measure biomarkers of inflammation and kidney, nerves, heart and blood vessels damage. participants will also be comprehensively phenotyped for diabetic complications outcomes, diabetes kidney disease, diabetes neuropathy and cardiovascular disease. Participants will be asked to fill out questionnaires to assess psychosocial metrics. The rationale is that correlating markers of acute hyperinflammation (cytokine storm syndrome) at admission in diabetes patients can inform vigilance and care for long term complications in survivors. Completing these studies will generate evidence-based guidelines for mitigating sequelae in diabetes COVID-19 survivors and identify critical psychosocial factors to mitigate psychological harm.
Being active has a beneficial effect on human immunology. Patients hospitalized for COVID-19 (coronavirus disease 2019) will be surveyed for their prior physical activity. In order to show the relationship between the level of usual physical activity and the course of the disease, the following variables will be monitored to express the disease severity: death or transfer to ICU (intensive care unit), or recovery, also the length of hospitalization will be analyzed as a secondary outcome. Depending on the availability of data, the following will also be analyzed: complications other than respiratory failure, C-reactive protein (CRP) and procalcitonin (PCT) levels on admission, and other laboratory parameters, need for oxygen therapy.
The study RECOVER is a randomized, open-label, multicenter phase II trial, designed to assess the clinical outcome of SARS-CoV-2 disease in high-risk patients (group 1 to group 4) following treatment with anti-SARS-CoV-2 convalescent/vaccine-boosted plasma or standard of care.
