Active clinical trials for "COVID-19"

The glycocalyx is a membrane coat composed of glycoproteins attached to the surface of cell membranes. Recent publications have drawn attention to the potential role of a degradation of the endothelial glycocalyx (a kind of gel that lines all the vessels of the body) during the SARS-CoV-2 (Severe Acute Respiratory Syndrome - coronavirus 2) epidemic. The work of Yamaoka-Tojo et al. reveals vascular endothelial dysfunction in patients at high risk for developing a severe form of COVID 19. This observation prompts further investigation of vascular endothelial function in SARS-CoV-2-infected patients, and particularly those with long COVID. As of the end of the first COVID-19 epidemic wave in May 2020, persistence of symptoms several weeks or months after the first manifestations of COVID-19 was described in more than 20% of patients after 5 weeks and in more than 10% after 3 months). The term "long COVID" describes this phenomenon of prolonged symptoms following COVID-19. The French National Authority for Health has established criteria to identify people with prolonged symptoms after an initial episode of clinically and/or biologically documented COVID-19: an initial symptomatic episode, the presence of at least one of the initial symptoms beyond 4 weeks after the onset of the acute phase of the disease, and initial and prolonged symptoms not explained by another diagnosis not known to be related to COVID-19. Among the observations reported in patients with long COVID, ophthalmic involvement is poorly described. A team of ophthalmologists of the Rothschild Foundation has demonstrated (using indocyanine green angiography, adaptive optics and optical coherence tomography techniques) disorders of the choroidal circulation, with abnormalities of the vascular walls, presence of "pachyvessels" and "caverns", in COVID-positive patients hospitalized at 6 months of their hospitalization.

The main purpose is to study the prevalence of Covid-19 in EHPAD. The primary endpoint will be the combination of PCR results and symptomatology, making it possible to define positive cases in EHPAD, in residents and professionals in contact with them. The prevalence obtained can be compared with the results of serology if these are performed.

The ongoing coronavirus disease 2019 (COVID-19) which started in China, was declared on the 11th of March as a global pandemic 2020 by the World Health Organization (WHO). Governments around the world have introduced differing forms of lock downs since the start of the pandemic demanding citizens to confine to their homes and go out only in necessity to minimize exposure to the virus. The response was observed in the emergency departments and the number of patients who presented for non-Covid issues drastically reduced. Hospitals activated their mass casualty management plans and have reorganized and overstretched their capacity to be able to absorb both the influx of patients with the virus and those with other conditions. Part of that reorganization was reducing the surgical activity. The main focus was shifted to patients who are considered urgent and elective surgery were postponed. Hence only surgical emergencies were maintained. Many did not present to the emergency department for fear to contract the virus and from a sense of national and global solidarity against that pandemic. Whereas these measures are essential to prevent the spread of the virus, it may be hypothesized that for non-Covid issues, including surgical emergencies, patients may present late to the emergency department due to fear of contracting the infection in hospital. This would delay their management and lead to a worsened symptomology on presentation requiring a more complex surgical intervention with an increased complication profile. The investigators present initial data from four major hospitals in Belgium, characterizing surgical emergencies that were managed since the start of the pandemic and discuss the repercussion the pandemic has on management of urgent surgical patients and most likely evolution of surgery after the pandemic.

This non-interventional, biospecimen collection study is designed to help us better understand whether MS patients have impaired immune defenses to COVID-19 infection. The potential influence of immune modulating medications for MS will be considered through these exploratory studies. This study is also designed to provide context for interpretation of anti-SARS CoV2 serologies in MS patients during convalescence from COVID-19 infection.

The COVID-19 pandemic is a challenge for the French healthcare system, particularly among the elderly due to their particular vulnerability to the serious consequences of the disease, with an estimated mortality rate of around 30-35% among the frail elderly. The management of the health crisis could take a new turn in 2021 with the arrival in France of vaccines against the SARS-CoV-2 virus. The objectives of this vaccination campaign are to reduce the morbi-mortality attributable to COVID-19 on the one hand, and to maintain essential activities related to the functioning of the country on the other hand and in particular the health system. However, the distrust of vaccination, traditionally strong in France, could have a negative impact on this strategy. While the President of the Republic announced on November 24, 2020 that vaccination against SARS-CoV-2 would not be made compulsory, almost one French person in two declared in several surveys that they did not want to be vaccinated; the main criterion for acceptance of vaccination being advanced age (the older they are, the more French people declare accepting to be vaccinated). In view of the gradual vaccine supply schedule for the year 2021, the French National Authority for Health established at the end of 2020 a prioritization by vaccine availability phases. The critical initial supply phase,which is currently taking place, is the one during which residents of retirement home and long-term care units are prioritized because of their particular vulnerability (age and co-morbidities) and their increased exposure to SARS-CoV-2. For these reasons, and in order to carry out the current vaccination campaign in the most optimal way possible, this national survey is launching to evaluate the acceptance rate of the SARS-CoV-2 vaccine among people living in retirement homes and long-term care units, to understand the mechanisms of acceptance or rejection, and to draw up an initial large-scale inventory of the symptoms observed following vaccination.

The main objective of this project is: 1. To assess the impact of COVID-19 on the brain and executive functioning. Twenty adult subjects of UZ Brussels (volunteers), who needed intensive care due to COVID-19 (n=10) or exhibited mild symptoms due to COVID-19 (n=10), will be recruited after hospital discharge. After signing an informed consent the subjects will undergo brain scans (T1, DTI, SWI, DWI, FLAIR MRI and rsfMRI), an emotion regulation task and a neurocognitive test battery. The latter test battery will be performed using an iPad and will test different neurocognitive functions such as memory, abstract thinking, spatial orientation and attention. The duration of the test battery is 18min. The total duration of one trial is estimated at one hour and a half. All tests are planned at the department of Radiology-Magnetic Resonance (UZ Brussel). After three months patients will visit the department of Radiology-Magnetic Resonance a second time for the same experimental trial. Additionally, a matched control group (n = 20; non covid or ICU patients) will be included and undergo the same tests in order to compare the results of the brain scans, emotional regulation task and neurocognitive test battery with results of both Covid-groups. Next to objective data, questionnaires will be filled out, i.e. visual analogue scales of mental and physical fatigue, Profile of Mood States and some additional return to work questions.

The COVID-19 pandemic has negatively affected individuals not only physiologically but also psychologically. The aim of this study is to examine the anxiety and depression status of cancer patients, individuals with non-cancer chronic diseases and healthy individuals with an online screening questionnaire during the COVID-19 pandemic period.

Loss of smell is very frequently found in Europe during Covid-19 attack. This symptom was not initially expected as part of the classic symptomatology. This loss of smell mainly concerns patients with few or no symptoms, without criteria of severity and usually treated on an outpatient basis. As a result, given the unexpected occurrence of this symptom (with less awareness in the general and medical population) and the potential risk of contamination of Covid+ and anosmic subjects (due to their less symptomatic form), it is interesting to be able to propose large-scale screening for loss of sense of smell in order to preferentially direct subjects diagnosed as anosmic towards RT-PCR-type screening. In the medium term, the loss of smell seems to persist after the infectious phase, with delayed or persistent recovery, which can lead to negative psychological repercussions. The objective is to propose large-scale screening of the general population for loss of sense of smell during a pandemic period, in order to facilitate diagnostic orientation of the population. The diagnosis of loss of smell will be carried out using a simple olfactory test in the form of an olfactory stick to be smelled.

Since the beginning of the COVID-19 outbreak in France, nursing homes (NH) have been heavily affected. In this study, the investigators want to evaluate the factors associated with the occurrence of COVID-19 epidemic clusters within the nursing homes in the French Alps

The objective of the National Survey of Early Care and Education (NSECE) is to document the nation's current supply of early care and education (ECE) services. Because the COVID-19 pandemic is likely to have had an impact on the ECE supply, and because the availability of ECE services is critical to restoring the U.S. economy, updated data on the ECE supply will be crucial for policy-making and research. The purpose of the NSECE COVID-19 Follow-up Study is to describe the impact of the COVID-19 pandemic on the pre-pandemic ECE supply and the ECE workforce, including changes in supply or departures from and re-entries to the workforce. Data from the study can be used to estimate the impact of the pandemic on ECE supply and the financial health of ECE providers, as well as providers' experiences during and after the pandemic emergency. Through a two-wave design, the NSECE COVID-19 Follow-up Study data will trace providers' and workforce members' experiences from 2019, through the initial months of the pandemic (to be reported in the Wave 1 interview), and then to the one-year point since the onset of the pandemic (to be reported in the Wave 2 interview). This design is intended to capture the trajectories of providers and workforce members, for example through recovery back to full or modified participation in ECE supply, or long-term exits from ECE supply. Prospectively collecting these data allows inference about the types of providers and workforce members most likely to have exited or survived in ECE, as well as the programmatic supports received by those who remain in ECE at the time of the second interview.
