Filter by:Approximately 100 patients undergoing oral surgery will be divided in 3 groups of musical audition to control anxiety: baroque (N=35), classicism (N=35) and control group (N=30). Systolic Blood Pressure, Diastolic Blood Pressure, Heart Rate and Oxygen Saturation will be recorded.
The infectious coronavirus disease of 2019 (COVID-19), caused by corona virus SARS-severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) has caused significant disruption in surgical services to patients globally. Data from the COVIDSurg Cohort Study suggest mortality rates of patients infected with SARS-Cov-2 in the peri-operative period of up to 25.6% in emergency surgery and 18.9% in elective surgery. Based on estimates by the COVIDSurg Collaborative, large numbers of elective surgical procedures are cancelled. The COVID-19 pandemic has forced healthcare providers to 'shift from patient-centred ethics to public health ethics'. This has had impact on pre-operative testing for COVID-19, and scheduling of surgery. Currently, a provisional recommendation to delay surgery for at least four weeks after a positive COVID test, exists. Weighing the risk of surgery and potential complications during the COVID-19 pandemic, against the benefit of undergoing a surgical procedure to improve quality of life, remains difficult. A study to determine the long term effect of the pandemic on patient-reported outcome may provide guidance on how to safely return to surgical activity that are again more focused on individualized care. There is also the opportunity to record outcomes that are currently accepted as the standard for understanding longer term recovery after surgery.
A prospective cohort study to evaluate the response to COVID-19 vaccine in liver transplantation patients.
This study is a continuation study of the original V-01-I phase trial, using a single-center, single-arm, open design to evaluate the immunogenicity and safety of the third dose booster immunization of Recombinant SARS-CoV-2 Fusion Protein Vaccine (V-01) in healthy participants immunized with two doses schedule of V-01. The primary objective is to evaluate the Immunogenicity of the third dose booster immunization of V-01 in healthy participants immunized with two doses schedule of V-01. The secondary objective is to evaluate the safety of the third dose booster immunization of V-01 in healthy participants immunized with two doses schedule of V-01.
This prospective, multi-center, randomized, observer-blind Phase 2 study. A total of 1320 participants will be divided into 2 groups (660 each) receiving either full dose or half dose of either AZ or PF. Each group is further stratified into 3 subgroups according to three interval duration in term of days after second dose of SV for 60 to less than 90 days, 90 to less than120 days and 120 to 180 days. Each group will be randomized to receive either AZ or PF in 1:1 ratio. Subjects who fulfilled eligibility criteria will be randomly assigned to receive either full dose or half dose of AZ or PF in 1:1 ratio as an IM injection in the deltoid muscle at Visit 1 (V1). Subjects will be follow-up for assessing immunity at day 28 (V3), day 60 (V4) and day 90 (V5) and for safety at day 7 (V2), day 28 (V3), day 60 (V4) and day 90 (V5). At least 50% from each subgroup will be randomly selected to provide additional blood at baseline (V1, day 0) and day 28 (V3) to be used for assessment of T-cell-mediated immunity (CMI)
The goal of this study is to recruit confirmed Covid-19 patients, to evaluate whether the topical anti-septic can improve clinical outcome in early Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) infection. During the global pandemic period, an effective and highly available method once be identified, it will reduce the risk of disease transmission and lower the medical burden.
This report is a multicenter, observational, analytical and prospective study. The objective was to describe the weaning of mechanical ventilation in patients with SARS-CoV-2 and the clinical results according to the different types of weaning.
Rationale: Early in the covid-19 pandemic, it was unclear whether and how individuals and populations would develop protective and enduring immunity against SARS-CoV-2, either after infection or vaccination. It is still not clear what role might immune cellular responses play in the development of immunity to SARS-CoV-2 infection and what are the implications for vaccines? As T cells recognise and respond to viral antigens they produce many protective reactions and effector molecules. One such molecule is the cytokine interferon γ, secreted by CD4+ and CD8+ T cells and their memory cells. This can be measured means of documenting specific T cell responses to viral antigens. Published studies offered a strong evidence that T cell immune responses are sustained, even in the face of declining or undetectable antibodies, implying that some immunity persists. The evidence from new studies, interim results from phase III vaccine trials, and previous data from phase I and phase II trials support the notion that memory T cell responses to the vaccines, along with B cell antibody responses, should provide good and possibly enduring immunity to SARS-Cov-2. We propose to describe and characterize the humoral, innate and long-term adaptive immune responses and the neutralization potential generated by COVID-19 vaccination (Covaxin, Covishield) among healthcare and frontline workers.
Patients undergoing solid organ transplantation randomly selected from those who have received two doses of Spikevax (Moderna) vaccine, provided that a minimum of 8 weeks have elapsed from the second dose to the time of the start of the trial. It is planned to include 386 patients.
The purpose of this study is to assess the safety and immunogenicity of MVC-COV1901 vaccine who are generally healthy or with stable pre-existing health conditions and have received 2 doses of Placebo in the main study CT-COV-21
