Filter by:Contactless and widely available health monitoring technologies are of growing interest in the context of the worldwide COVID-19 pandemic. Remote photoplethysmography (rPPG) is a well-studied technology that interprets variations in skin colour related to blood flow which, when analysed with complex mathematical algorithm, generates vital sign readings. This technology has been refined and embedded in a smartphone app designed to acquire heart rate, respiratory rate and oxygen saturation using a front-facing smartphone camera. Preliminary data comparing the accuracy of smartphone rPPG readings with conventional vital sign monitor readings are promising; however, less than 5% of the population studied in the app development phase had oxygen saturation levels below 95% making it impossible to ensure reliability in these populations. The goal of this study is to compare readings acquired using this rPPG app with the readings from hospital grade, Health Canada approved vital signs monitors used in healthcare settings with a focus on subject with low oxygen saturations. We will also study other sociodemographic and clinical features that may influence the accuracy of the readings. This will be achieved by recruiting consenting adults presenting to care in acute care settings and a designated COVID outpatient clinic. Vital signs will be acquired using the rPPG app and conventional hospital vital sign monitors simultaneously. Readings will be repeated within 2-5 minutes when time permits. Statistical analysis will be performed to analyze the findings and determine the accuracy and precision of the rPPG app readings. It is expected that the vital sign readings acquired with the rPPG app will be almost identical to those acquired using hospital-grade monitors for all subjects regardless of age, gender, skin colour, COVID status and relevant comorbidities.
Background: Coronavirus (CoViD-19) positive stroke survivors (SSv) with comorbidities faces possibility for mortality. Study reports success of physiotherapy in CoViD-19 positive SSv with multiple comorbidities. Methods: This clinical controlled study involve a minimum of 30 SSv and 30 age and sex-matched non-stroke individuals with multiple comorbidities with CoViD-19 status confirmed using Real-Time Quantitative-Polymerase Chain Reaction. The Cycle Threshold (CT) and nucleic acid content in the test sample (NA) will be recorded from the virology test results. Their exercise endurance, exercise capacities and quality of life will be assessed using 3-minutes' walk test and 3-meters test and Stroke Specific Quality of Life Questionnaire. Measurements will be taken at every three days intervals from admission to discharge from hospital-isolation. They will receive their normal treatments for CoViD-19 in addition to daily Physiotherapy for the SSv delivered through E-Platform. the Zoom and the WhatsApp video platforms will be used for the interactions between the physiotherapists and the participants. A pre-tested exercise protocol for stroke patients developed by the Stroke and Nervous System Disorders research group of the University of Lagos, Nigeria will be used for the E-exercises. The exercise package will be loaded into the phones of the participants at hospital admission. The Physiotherapists will lead in the exercises through video interaction will the participants watches the video programme. Their risks for respiratory complications (RC), ventilation (RV) and death (RD) will be analysed. Data will be analysed using independent t-test, Analysis of Co-Variance, and multivariate retrogression, survival analyses, Friedman Analysis of Variance and MannWithney U test (95% Confident Interval). Anticipated Outcomes: It is anticipated that the outcome of this study will provide evidence for inclusion of Physiotherapy in the acute management of individuals tested positive for CoViD-19 most important for the stroke survivors tested positive for CoViD-19 at acute stage to reduce the odds of developing complications expedite discharge and reduce odd of death.
This study will provide access to investigational anti-SARS-CoV-2 human convalescent plasma for pediatric patients with underlying medical conditions (cardiovascular disease, lung disease, immunosuppression) who are either infected with SARS-CoV-2 or who have had a high-risk exposure. Study participants will be transfused once with compatible convalescent plasma obtained from an individual who has recovered from documented infection with SARS-CoV-2. Safety information and pharmacokinetic data will be collected.
This study is a prospective, single center, observational, cohort study of patients to (1) describe the kinetics and temporal relationship of changes in eicosanoid and cytokine mediators in patients with severe COVID-19 admitted to the hospital; and (2) correlate the dynamic changes in eicosanoid mediators with available patient clinical status, including measures of severity of illness, routine laboratory tests, and outcomes.
SARS-CoV-2 or COVID-19 is representing the major global burden that implicated more than 10 million infected cases and 500 thousand deaths worldwide. The prevalence of this pandemic disease is expected to rise every day. The challenge is to control its rapid spread meanwhile looking for a specific treatment to improve patient outcomes. Hesperidin is a classical herbal medicine used worldwide for a long time with an excellent safety profile. Hesperidin is a well-known herbal medication used as an antioxidant and anti-inflammatory agent. Available shreds of evidence support the promising use of hesperidin in prophylaxis and treatment of COVID 19. Herein, we discuss the possible prophylactic and treatment mechanisms of hesperidin based on previous and recent findings. Hesperidin can block coronavirus from entering host cells through ACE2 receptors which can prevent the infection. Anti-viral activity of hesperidin might constitute a treatment option for COVID-19 through improving host cellular immunity against infection and its good anti-inflammatory activity may help in controlling cytokine storm. Hesperidin mixture with diosmin co-administrated with heparin protect against venous thromboembolism which may prevent disease progression. Based on that, hesperidin might be used as a meaningful prophylactic agent and a promising adjuvant treatment option against SARS-CoV-2 infection.
Background: The rapid spread and high infectivity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) makes identifying an effective prophylaxis agent highly important. One of the important target populations for such intervention who are at high risk of exposure are health care workers (HCWs) who may develop disease and/or expose patients and other HCWs. Hydroxychloroquine (HCQ), currently in usage for treatment of severe Coronavirus Disease 2019 (COVID-19), has in addition to in-vitro activities of inhibition of virus replication and immunomodulation, an important role in the inhibition of pre-entry step of the virus to host cells. Such activity in the early stage of infection may play a role in prevention of disease progression. Objectives: To evaluate the effect of HCQ in prevention of clinical disease and reduction of viral shedding among HCWs following exposure to confirmed COVID-19 patients. Study design: Multi-center, randomized controlled, superiority, open label trial Setting: The study will be conducted at Rambam Health Care Campus. Eligibility: Participants eligible for inclusion will include non-pregnant adult (>18 years old) HCWs who were exposed to a confirmed case of COVID-19 without full adherence to droplet precautions. Participants will be eligible in a period no longer than 72 hours after exposure. Intervention: HCQ will be given in the intervention group in a dosage regimen of 400mg BID in the first day followed by 200mg BID for overall 10 days. Participants in the control group will receive no treatment. Treatment will be started no longer than 72 hours following exposure. Outcomes: The primary outcome will be the number of participants who develop clinical signs compatible with COVID 19 (defined in full protocol) within 14 days of exposure. Secondary outcomes will include virologically-confirmed COVID 19, disease severity (need for hospitalization, mechanical ventilation and 30-day mortality) and viral shedding duration (time between first positive PCR to last of two consecutive negative tests) for confirmed COVID 19 cases. Sample size: The trial will test for HCQ's superiority assuming a primary outcome incidence of 20% in the control group and a reduction of 50% with HCQ. The sample size required for a power of 80% (alpha 0.05) is 291 participants per each group.
This is a cohort study of COVID-19 patients with hyperinflammation. It aims to determine the impact of adjunctive Tocilizumab (TCZ) to standard of care on the reduction of hyperinflammation-related mortality in COVID-19. Patients with COVID-19 are at high risk of life-threatening hyperinflammation and death. One in three COVID-19 patients admitted to ICU was found to develop life-threatening hyperinflammation. The risk of death when untreated is estimated to be 50-80%.
In-vitro studies revealed that nafamostat mesylate has antiviral activity against Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and anti-inflammatory and anti-coagulation effect. However, there is no clinical studies on the efficacy of nafamostat in patients with COVID-19. This study is conducted to evaluate the clinical efficacy of nafamostate mesylate in adult patients hospitalized with COVID-19 pneumonia.
COronaVIrus Disease or Severe Acute Respiratory Syndrome -CoV-2 or COVID-19, mortality occurs mainly from immunological behavior or by suicide after healing . In both cases, the causal link is coronavirus within the host response. The rationale of use of deep yoga breathing as adjuvant treatment to COVID-19 disease , is linked to the mechanical action to stimulate the vagus nerve through scalene and sternocleidomastoid muscles function of which the continuity of action bring to modulate upto suppress, the inflammatory reflex and pro-inflammatory cytokines overproduction and contextual lowering of the sympathetic stress response as a first cause of sleep and late mental disorders which can increase the annual suicide rate. An easily breathing medical Yoga protocol has been developed to test a cost-effective care provision, training, contact tracing and mass efficacy testing.
