Filter by:Vaccines often underperform in Africa compared to high-income countries. Why vaccines do not work as well in Africa remains uncertain. Malnutrition likely plays a role. Our study objective is to assess whether iron deficiency anaemia in young women impairs their immune response to the COVID-19 vaccine, and whether iron treatment improves their response.
This is an observational study of participants in three general population health surveys (FinSote 2018, 2019, 2020) who are followed up until the incidence of SARS-CoV-2 infection or end of follow-up. The primary objective is to examine the association between tobacco use and the risk of SARS-CoV-2 infection in a general population sample in Finland.
The epidemic caused by the new coronavirus appeared in December 2019 and spread rapidly, and it has had a serious impact on the social development and people's lives in the world. On February 11, 2020, the World Health Organization (WHO) named the infectious disease caused by the virus COVID-19. my country classifies it as a Class B infectious disease, and controls it as a Class A infectious disease. In order to effectively respond to the epidemic, on January 23, 2020, Zhejiang Province first launched a first-level response to major public health emergencies across the country. Some patients with new coronary pneumonia, especially critically ill patients, may go to the emergency department first. Emergency medical staff must identify and isolate patients with new coronary pneumonia in a timely manner while ensuring the treatment of critically ill patients. People face greater unknowns and challenges in the anti-epidemic work. this research Participating in the prevention and control of the new crown pneumonia epidemic through investigations in the emergency department of Zhejiang Province Related conditions, to further improve the hospital's emergency medical service capabilities for reference.
Since late December 2019, the novel human coronavirus (SARS-CoV-2) first reported in China, has spread worldwide. Vaccines to prevent SARS-CoV-2 infections have been developed in record time and several candidate vaccines have completed Phase 2a/b and Phase 3 clinical trials. Coronaviruses (CoVs) are spherical, enveloped viruses with positive-sense single-stranded RNA genomes. One fourth of their genome is responsible for coding structural proteins, such as the Spike (S) glycoprotein, envelope, membrane, and nucleocapsid proteins. Envelope, membrane, and nucleocapsid proteins are mainly responsible for virion assembly whilst the S protein is involved in receptor binding, mediating virus entry into host cells during CoVs infection via different receptors. SARS-CoV-2 belongs to the phylogenetic lineage B of the genus Betacoronavirus and it recognizes the ACE2 as the entry receptor. It is the seventh CoV known to cause human infections and the third known to cause severe disease after SARS-CoV and MERS-CoV. AZD1222 is a recombinant replication-defective chimpanzee adenovirus vaccine expressing the SARS-CoV-2 S surface glycoprotein. Development of AZD1222, previously referred to as ChAdOx1 nCoV-19, was initiated by the University of Oxford, UK, with subsequent transfer of development activities to AstraZeneca. The ChAdOx1 platform has been used in 14 clinical studies sponsored by the University of Oxford with immunogens from multiple pathogens such as influenza, tuberculosis, malaria, chikungunya, Zika, MERS-CoV, and Meningitis B. Over 360 healthy adult participants have received ChAdOx1-vectored vaccines in these studies. These vaccines demonstrated robust immunogenicity after a single dose and favourable safety profiles, with no vaccine-related serious adverse events (SAEs).
The world is currently facing a crisis because of this potentially fatal situation of the COVID-19 epidemic without proven efficacy for any drug treatment, while the vaccination is not yet. This epidemic is caused by a new betacorona virus, now called SARS-CoV-2. The most common symptoms reported are fever, cough or chest tightness, and dyspnea. Most cases have a mild course
The MEXICO study is an observational study that aims to identify underlying mechanisms contributing to exercise intolerance in the presence of persistent COVID-19 symptoms (Long COVID).
This is a randomized (1:1), double-blind, placebo-controlled phase 2 study to assess safety and efficacy of Total TQ Formula (3 g daily dose of Nigella Sativa Oil) capsules versus placebo in treating patients who have tested positive for novel Coronavirus 2019 (Covid-19) in the outpatient setting. Patients will be treated at a dose of 500 mg, 3 capsules, two times a day for 14 days from date of randomization. Quantitative viral load as measured by RT-PCR will be evaluated at baseline and on days 7 and 14. Covid-19 symptoms will be measured throughout the study using Modified FLU-PRO Plus.
The purpose of this study is to describe balance deficits in patients post COVID-19. The information the investigators learn may help influence balance training exercises for patients post-COVID-19. Participants will have a primary or secondary diagnosis of COVID-19 during hospitalization and off COVID-19 isolation and be receiving care in an acute inpatient hospital. Following consent, participants will complete balance assessments and questionnaires about balance and dizziness in a single session. Vital signs will be monitored during the session.The greatest risks of this study include shortness of breath, and a risk of falling or musculoskeletal soreness.These risks are no greater than those experienced during a usual physical therapy visit.
Screening early detection of invasive fungal sinusitis in COVID-19 positive patients
In order to assess the mother-to-infant and potential vertical transmission of SARS-CoV-2 infection in pregnant women, maternal and neonatal biological samples will be prospectively collected from women with confirmed or suspected COVID-19 at participating hospitals across Ontario. Samples will be tested for the SARS-CoV-2 serology and viral load. Outcomes for the study objective will be ascertained through the collection and testing of biological samples from the mother and/or infant. Specifically the investigators will: 1. Assess maternal nasopharyngeal or oropharyngeal swab, vaginal mucosa, ano-rectal swab, amniotic fluid, placenta (including subamniotic swab), breastmilk, cord blood and neonatal nasopharyngeal swab for RNA particles of coronavirus, by ddPCR. 2. Assess maternal serum for anti-coronavirus antibodies, by immunoassay. 3. Examine the impact of coronavirus on the neonate with respect to serology and viral load, in addition to placenta pathology findings and ddPCR. 4. Assess vertical transmission and the effect of coronavirus through placental pathology examination using placental pathology synoptic report.
