This is a Phase 2/3 randomized, observer-blinded, placebo-controlled, age de-escalation trial to evaluate the safety and immunogenicity of 2 primary doses and a booster dose of NVX CoV2373 given 21 days apart in pediatric participants (3 age cohorts; 6 to < 12 years, 2 to < 6 years, and 6 to < 24 months of age). Each age cohort will be conducted in 2 parts starting with the oldest age cohort (6 to < 12 years of age).
The purpose of this study is to recruit a total of 386 participants to evaluate the effectiveness of an educational program to increase the proportion of men and women aged 21 years and older who have received the COVID-19 booster vaccine
Acute kidney injury (AKI) in Covid-19 patients is a topic that receives little attention in the literature, although being important in clinical practice in the ICU, particularly in Oman. Our objective was to determine the incidence of AKI, risk factors, and the requirement of renal replacement treatment. Methods: All adult patients hospitalized at Sultan Qaboos University Hospital in the critical care unit (ICU) between March 2020 and September 2021 with laboratory-confirmed Covid-19 had their medical records retrospectively reviewed. All patient characteristics, their course of events, and the treatment received in ICU were noted. The incidence of AKI, its association with the glycemic index, and other possible risk factors will be studied. Those requiring renal replacement therapy will be studied in terms of its predictors and outcomes.
The purpose of this study is to describe the long-term health effects of COVID-19 in a population of mostly Black and Latinx individuals and their households who were diagnosed with COVID-19 at Columbia University Irving Medical Center. In New York, the upper Manhattan and south Bronx communities neighboring Columbia University Irving Medical Center (CUIMC) have been two of the most impacted communities of the COVID-19 pandemic. These neighborhoods are predominantly non-Hispanic black or African American and Latinx. This study will invite people who tested positive for COVID-19 and/or were treated at Columbia University Irving Medical Center to: 1) take a survey to ask about current symptoms and any health problems and 2) ask permission to review COVID-related health history including COVID-19 testing results (from the medical record) since infection to learn about health effects after COVID-19 infection; 3) invite anyone in their household to take a survey; and 4) for up to 500 patients who were hospitalized for COVID, give the option of doing a nasal swab to test for SARS-CoV-2 virus and blood test to check for antibody up to 12 months after diagnosis, to compare how results are different 12 months after infection. The goal is to learn about how the severity of person's infection in 2020 influences long term health effects and how others in their household are impacted by COVID-19.
The goal of this project is to understand the household level transmission dynamics and factors that predict transmission of SARS-COV-2 between pediatric and adults in the household. The novel coronavirus SARS-CoV-2 has spread all around the world and testing has posed a challenge globally. Not much is known about who does and does not acquire SARS-CoV2. It is also unknown who will show symptoms or progress severe disease or death from COVID-19. Children tend to have milder symptoms or none at all. Therefore, few children have ever been tested, so it is unknown if they get the infection as much as anyone else. Health care providers are highly exposed, and they do not get tested unless they show severe symptoms. If groups like children and health workers are infected, they can unknowingly spread SARS-CoV-2, unless they practice behaviors like self-isolation very strictly. The investigators aim to measure the prevalence of SARS-CoV-2 in children and health care workers at a large urban health center. The investigators will also measure how many people in the household of the positive children and health care workers also get SARS-CoV-2 infection. Lastly, the investigators will see what other risk factors affect who acquires SARSCoV-2 from inside or outside of the household clusters.
This is a randomized, phase Ⅱ, single-blind, randomized, parallel-group controlled clinical trial. The study plans to enroll subjects who have completed homologous primary vaccination with either inactivated or mRNA or Viral Vector COVID-19 vaccines (one or two doses) and have not been infected with COVID-19. All subjects will be evaluated for safety and immunogenicity after a single dose booster immunization with Recombinant COVID-19 variant Vaccine (Sf9 Cell) or inactivated COVID-19 vaccine (Vero cell) or mRNA vaccine or Viral Vector vaccine.
Chronic lymphocytic leukaemia (CLL) is a common lymphoid malignancy affecting older adults. CLL patients are immunocompromised by the disease itself and by several of its therapies. It has now been shown that many CLL patients do not mount an antibody response following COVID-19 vaccination and are therefore at risk of COVID-19 infection. Furthermore, patients with hematologic malignancies are known to be at increased risk of severe infection if they do acquire COVID-19 infection. The purpose of this trial is to document evidence of passive immunity to COVID-19 infection after EVUSHELD administration with serologic and neutralization assays at multiple post administration time points in patients with no response to standard of care vaccination to COVID-19. This trial will include a single dose of EVUSHELD to be administered, with a 1-year follow-up period, comprising of 8 health status visits. Blood samples will be taken at screening, baseline and at multiple health status visits over the course of the year for various antibody testing and analysis. T cell reactivity to COVID-19 epitopes will be studied at baseline and again monthly for 3 months in any participants that become infected with COVID-19.
Tracheostomy is commonly indicated for the patient who is requiring long period of mechanical ventilation. Patient who require mechanical ventilation for >10 days and longer mostly get tracheostomized. Tracheostomy is associated with less complications associated with endotracheal intubation. Tracheostomy is a surgical procedure whereby an external artificial opening is made in the trachea. Several techniques are used to perform tracheostomy, including the classical standard surgical procedure completed in a surgical room and the percutaneous method performed at the patient's bedside. Surgical and percutaneous procedures are usually performed by different surgical specialists such as general; thoracic; ear, nose and throat (ENT); or maxillofacial surgeons, but percutaneous procedures are usually but not exclusively performed by surgeons and intensivists. Early tracheostomy might reduce the length of ICU stay, whereas delaying the tracheostomy might avoid a few. A review of recent studies showed a decrease in the mortality rate in early tracheostomised patients compared with late. Tracheostomy is a routine bedside procedure in ICU with minimal complications. Severe acute respiratory syndrome (SARS) and Coronavirus 2 (SARS-CoV-2) started to appear in Oman in early February 2020, resulting in an escalation of new cases within days. In the first weeks of the pandemic, many guidelines from different specialties recommended avoiding early tracheostomy to minimize the risk of infection to clinicians. Specifically, recommendations for tracheostomy in the current pandemic were rooted in the assumption that maximal infectivity of this novel virus occurred around day 7 to 10 after symptom onset, and performing tracheostomy at that time would endanger maximal risk to those performing it. Hence these factors interfered with the timing of Tracheostomy for Covid patients. This is an observational cohort study. It will assess patients admitted to ICU at SQUH during the period between January 2020 and December 2021 with Non-Covid and Covid-19 patients. This study will assess the causes and outcomes of early and late tracheostomy in Non-Covid and Covid-19 patients requiring mechanical ventilation. Main outcomes will include mortality rate, ventilation days, and ICU length of stay.
