Filter by:The Sponsor has developed a rapid screening tool intended to determine if the subject tested has COVID-19.
This is a randomized, phase II trial which will be conducted among volunteers aged 18 years and above in Karachi, Lahore and Islamabad, Pakistan. The trial will have nine arms and is an open label study. Trained persons will administer the vaccine and draw blood under strict aseptic measures. The immune responses using pseudo neutralizing antibodies against SARS-CoV-2 in COVID-19 seronegative participants receiving heterologous and homologous COVID-19 vaccines will be assessed. Anti-spike IgG antibodies by ELISA and pseudo neutralizing antibodies against SARS-CoV-2 will also be measured. The safety and reactogenicity will also be assessed by recording serious adverse events (SAE), adverse events of special interest (AESI), solicited local and systemic reactions and medically attended adverse reactions through biochemical and hematological tests or safety measures throughout the study. In most cases the adverse events are mild and self-limiting but can require medication and/or hospitalization in rare cases. Participants suffering from any adverse event causally related to the to the trial intervention will be facilitated and the cost of treatment including laboratory investigations will be provided to them. Data confidentiality will be ensured by delinking names in forms and through password protection.
COVID-19 has significant detrimental impacts on surgical systems and patient outcomes. CovidSurg has provided the best available evidence to guide delivery of safe surgery during the pandemic. However, CovidSurg data were collected in 2020 when the wildtype SARS-CoV-2 virus was dominant, and therefore there is a need to for renewed rapid data to guide global practice during Omicron COVID-19 waves. CovidSurg-3 is an extension to CovidSurg and was initiated in response to the emergence of the Omicron variant. CovidSurg-3 has two separate components: - Patient-level component: Collection of outcome data for patients with peri-operative SARS-CoV-2. - Hospital-level component: Collection of aggregated case-mix data. Hospitals in countries with low community SARS-CoV-2 infection rates can contribute towards this component.
Introduction: A pandemic such as the SRAS-CoV-2 (COVID-19) has a great negative socioeconomic impact with very limited therapeutic options. As with any disease, a detailed understanding of its pathophysiological mechanisms is critical for the development of new therapies. In SRAS-CoV-2, few studies have verified a possible relationship of these vasoactive peptide polymorphisms with patient prognosis. Objective: To analyze and relate polymorphisms found in components of vasoactive peptide systems in DNA samples collected from patients diagnosed with SARS-CoV-2 (COVID-19) who developed severe conditions and patients infected with mild or asymptomatic conditions. Methodology: Cross-sectional, analytical and qualitative study that will be conducted with approximately 151 participants previously diagnosed with SARS-CoV-2 with mild or asymptomatic forms of the pathology, diagnosed in primary care in the city of Guarulhos/SP- specifically in the Basic Health Unit of Nova Saúde Bonsucesso- well with participants who were diagnosed with the severe forms that required hospitalization in 2021. For the collection of biological material, a sterile swab will be used in order to collect cells from the oral cavity, specifically from the oral mucosa. Expected results: We hope to identify and relate the polymorphisms of vasoactive peptide genes from patients with mild, asymptomatic or severe forms of SARS-CoV-2 infection, thus contributing to the understanding of the different clinical evolutions of the disease.
To study the risk of hypoxia in placenta of normal pregnant women infected with covid-19 during third trimester of pregnancy.
investigate the diagnostic ability of thoracic ultrasound in suspicious COVID-19 infection and/or COVID-19 pneumonia. Also, to compare its findings to CT and follow up these findings.
The purpose of this study is to determine whether nitazoxanide (NTZ) is safe and effective for treatment of mild COVID-19 illness. Adults and adolescent participants will be followed for approximately 28 days.
The purpose of this study is to determine whether nitazoxanide (NTZ) is safe and effective in treating mild or moderate COVID-19 illness in adults and adolescents at highest risk for severe outcomes. Each participant will be followed for approximately 28 days.
COVID-19 has emerged as a global pandemic. It is mainly manifested as pneumonia which may deteriorate into severe respiratory failure. The major hallmark of the disease is the systemic inflammatory immune response characterized by Cytokine Storm (CS). CS is marked by elevated levels of inflammatory cytokines, mainly interleukin-6 (IL-6), IL-8, IL-10, tumour necrosis factor-α (TNF-α) and interferon-γ (IFN-γ). Of these, IL-6 is found to be significantly associated with higher mortality. IL-6 is also a robust marker for predicting disease prognosis and deterioration of clinical profile. (1) IL-6 was detectable in the breath condensate of all the healthy non-smokers, but was significantly higher in the COPD patient. Exhaled breath condensate is totally non-invasive and highly acceptable to patients. The collection procedure has no effect on airway function or inflammation, and there is growing evidence that abnormalities in condensate composition may reflect biochemical changes in airway lining fluid. This method has been successfully used in previous studies to investigate several inflammatory markers in COPD and asthmatic patients. (2) Il-6 is produced in the lung by interstitial fibroblasts, alveolar macrophages, and large-vessel and bronchial epithelial cells. IL-6 levels are high in chronic inflammatory conditions of the lung, such as those due to allogeneic transplantation, bleomycin-induced fibrosis and a variety of human interstitial lung diseases. High levels of IL-6 have been found in the induced sputum of patients with COPD, particularly during exacerbation. Park et al. found increased IL-6 levels in the Bronchioalveolar lavage fluid of patients with non-specific interstitial pneumonia/fibrosis and in some patients with interstitial pneumonia. (3) the study involved 20 healthy controls and 20 patients with moderate to severe covid-19 according to cdc classifaction and 20 patients post covid-19 with lung fibrosis to estimate the measurment of interleukin-6 at exhaled condensate, this clinical randomized control study consists of 3 arms for 6 month ( all participants above 18 years non prgnant humans )
The purpose of the study is to test the feasibility and acceptability of a mindfulness- and acceptance-based smartphone app (MABSA) intervention for frontline nurses emotionally and psychologically impacted by the COVID-19 pandemic. The study will use a randomized controlled trial design of two groups: an intervention group of about 30 participants with posttraumatic stress symptoms and a wait-list control group of about 30 participants. The duration of the MABSA intervention is 6 weeks. The following are the outcomes to be measured: resilience, PTSD, mindfulness, experiential avoidance, and rumination.
