Active clinical trials for "COVID-19"

Coronavirus has caused containment of more than half of the world's population and a major and rapid reorganization of clinical and support services. The spread of coronavirus (COVID-19) has posed significant challenges for occupational health services. However, there is currently no data on the influence of this epidemic on the practice and feelings of dental surgeons and associates

(a) Objectives To assess the full lung function, exercise capacity, quality of life in patients with COVID-19 over 2 years. To assess the longevity of the serology response to SARS-CoV2. To investigate the association of the neutralization titer in plasma from different vaccinated cohorts to its protection of infection using in vivo model To investigate the SARS-CoV-2 specific cellular and humoral immunities as well as their determinant factors from community subjects who have received different types of COVID-19 vaccines. To assess the third booster dose for subjects who have poor antibody response despite having received two doses of CoronaVac (Sinovac)

The SARS-Cov2 pandemic remains associated with many concerns. One of the them is the real frequency of likely re-infection and subsequently the level of protection conferred by the acquired immunity following primary-infection. We propose to analyze a large set of laboratory data produced since the early beginning of the SARS-Cov2 spread in the French population to identify recurrent infection events and, more generally, gain insight about infection kinetics.

Wider research context: Since the recognition of SARS-CoV-2 outbreak in 2019, there are now over 126 million COVID-19 cases worldwide with more than 2.7 million deaths. Reports on neurological manifestations vary in prevalence rates (6-84%) and range from mild (headache, hyposmia, myalgia) to severe (encephalopathy, strokes, seizures). Little is known about long-term neurological outcomes of COVID-19 patients. The investigators propose a structured protocol to capture persistent and delayed neurological manifestations, neurocognitive deficits and quality of life (QoL) 3 and 12 months after COVID-19. Objectives: The investigators hypothesize that neurological manifestations and neuropsychological/cognitive deficits can be detected after COVID-19, substantially impact on patients' QoL and can be correlated with structural neuroimaging findings. Main objectives are to assess firstly long-term prevalence rates and natural history of neurological manifestations, secondly neuropsychological/cognitive deficits after COVID-19, thirdly the impact of COVID-19 on measures of mental health, QoL and functional outcome, fourthly to correlate neurological manifestations and distinct neurocognitive deficits with structural MRI abnormalities, and Fifthly to compare these results to age- and sex matched controls hospitalized with pneumonia (Cpneum) and to healthy controls for MRI-data (Chealthy). Approach: The investigators aim to enrol at least 225 patients with COVID-19, in addition to 50 Cpneum and 80 Chealthy. COVID-19 patients will include (group Oóne) outpatients presenting to the hospital, (group two) in-patients not requiring ICU admission, and (group three) patients admitted to the ICU. The investigators will not include asymptomatic patients, patients not presenting to the hospital, and those who do not consent to participate. The standardized protocol includes a firstly a structured neurological examination, secondly olfactory testing, thirdly assessment of QoL, mental health and functional outcome at 3 and 12 months, and fourthly screening for cognitive deficits (at 3 months) and a structured neuropsychological testing (at 12 months) in COVID-19 patients and controls. In a subset of at least 120 COVID-19 patients and 50 controls (Cpneum) high field MRI will be performed at 3 and 12 months. Innovation: The investigators aim to quantify COVID-19 related and specific neurological manifestations and their impact on the individual health condition. The novelty lies in the prospective design, the longitudinal follow-up including and the inclusion of a control group which allows us to explore the natural history of COVID-19 related neurological manifestations. Preliminary analysis of our ongoing 3-month follow-up suggests persistent neurological manifestations and a significant impact of COVID-19 on mental health, cognition and QoL. The investigators believe that our study results likely influence the long-term care of COVID-19 patients and help to identify those, who need further neuro-rehabilitative support

Although there are several licensed vaccines for SAR-CoV-2 (COVID-19) in Canada, none of them are approved for use in children under the age of 12, leaving five million children under 12 years unvaccinated. There is a need to find methods of mass rapid point of care testing in unvaccinated populations such as in schools that can be performed by a lay individual. This multi-center study will evaluate the clinical sensitivity of buccal swabs with the ID NOW COVID-19 device in comparison to standard of care COVID-19 testing at 15 pediatric emergency centres across Canada.

The purpose of the study is to examine whether a simple mindfulness intervention conducted via a virtual platform can reduce stress among pregnant women.

Gazelle COVID-19 is a fluorescent lateral flow immunoassay and accompanying Reader intended for the qualitative detection of nucleocapsid antigen from SARS-CoV-2 in nasal swab specimens from individuals who are suspected of COVID-19 by their healthcare provider within 5 days of symptom onset. The study will be conducted To obtain data to measure the positive percent agreement and negative percent agreement of the Gazelle COVID-19 Test compared to Reverse Transcriptase Polymerase Chain Reaction (RT-PCR).The study will assess Gazelle COVID-19 Test performance using dual mid-turbinate nasal swab samples. This study will primarily assess Gazelle COVID-19 Test performance on symptomatic subjects (within five days of onset of symptoms) at point of care (POC). A subset of asymptomatic subjects will be enrolled after the symptomatic subject enrollment is complete.

The study aims to implement and assess the impact of a multi-faceted intervention to support Primary Care Provider (PCP) outreach, and PCP and community organization dissemination of information to promote COVID-19 vaccination among vulnerable patients in and near Worcester, MA.

Several publications document the occurrence of prolonged or late-onset symptoms beyond 3 weeks after the first clinical manifestations of SARS-COV2 infection. These manifestations may be related to thromboembolic or inflammatory events or other mechanisms that are not yet well understood. The psychosomatic origin secondary to psychiatric disorders prior to the infection or in reaction to it is also to be evoked. The identification of the clinical manifestations observed, and their clinical and paraclinical evolution are essential to better understand the natural evolution of COVID-19, to specify the physiopathological mechanisms and to identify potential avenues of management for the patients. In addition, the impact of COVID-19 infection on primary care visits is not known. In general practice, these patients benefit from explorations and even diagnoses that may explain the persistence of symptoms (autoimmune diseases, thrombosis, somatoform disorders, hyperventilation syndrome, etc.). The objective of the COCO_Vi_LATE project is to carry out a cross-sectional study of patients presenting persistent and/or recurrent symptoms after an infection with SARS-COV-2 who will be compared to individuals with a short form of infection with COVID-19

The study comprise a nationwide, voluntary, on-line survey of inflammatory syndromes in children for retrospective (since 4th March 2020) and prospective data collection. Our aim was to capture and describe multisystem inflammatory syndrome in children (MIS-C) in Poland.
