Filter by:Hydrogen peroxide is produced physiologically by oral bacteria and plays a significant role in the balance of oral microecology since it is an important antimicrobial agent. In the epithelial cells, the enzyme superoxide dismutase catalyzes a reaction leading from hydrogen peroxide to the ion superoxide. The induced oxidative stress stimulates a local innate response via activation of the toll-like receptors and the NF-κB. Those kinds of reactions are also activated by viral infections. Virus-induced oxidative stress plays an important role in the regulation of the host immune system and the specific oxidant-sensitive pathway is one of the effective strategies against viral infections. Therefore, nose/mouth/throat washing with hydrogen peroxide may enhance those local innate responses to viral infections. The investigators hypothesised that a treatment with a mouth wash and a nasal spray containing a diluted solution of hydrogen peroxide may accelerate the negativisation rate of a positive PCR swab test for SARS-CoV-2 (COVID-19).
The aim of this study is to assess the incidence of bacterial surinfections (sepsis, VAP and catheter infections) in COVID-19 patients admitted to the ICU from 13th of March 2020 until 17h of October 2020. In addition, the association of these infections with the dose of corticosteroids, the length of stay in ICU and in hospital, the presence of venous thromboembolism, the number of bacterial episodes, the different types of bacteria causing the infections and ICU mortality will be evaluated as well as the associations between the presences of thrombi and bacteremia/catheter sepsis.
This is a Phase IV real-world, observational, non-interventional, prospective cohort study of adults vaccinated with AZD1222. The purpose of this study is to assess the safety and tolerability of AZD1222 in adults vaccinated in real-world settings.
The major impact of COVID-19 has been that the severity of respiratory symptoms require intensive hospital treatment. There is significant mortality and many of the survivors have a delayed recovery requiring intensive prolonged rehabilitation. COVID-19 is a multi-systemic disease in which different mechanisms within the body are affected; including the 'Gut microbiome'. 'Gut microbiome' refers to the bacteria living in intestines. While some bacteria is harmful, many are extremely beneficial and necessary for a healthy body. Many patients have gastrointestinal symptoms and there is a major change in the gut micro flora (microbiome), which may have an adverse effect on the respiratory symptoms. The probiotic, Sivomix, was given to hospitalized COVID-19 patients was associated with a more rapid recovery in gastrointestinal symptoms on day 3 and 7, and an eight fold reduction in the requirement for mechanical ventilation in an open trial. This is a randomized clinical trial, with a recruitment target of 60 patients admitted with COVID-19 symptoms to the general medical wards. Patients will be randomized to receive the probiotic, Symprove, or placebo in addition to their standard of care treatment. Patients will need take either probiotic/placebo daily for 3 months. All follow-up will be whilst they are an inpatient or as a telephone follow-up; they will not need to attend at the hospital to participate. There is a biological sub-study incorporated into the protocol, but participation is optional. If patients consent to this, they will also need to provide blood, faecal and saliva samples at baseline, Day 7 and final visit (3 months after randomisation). Patients who consent to providing biological samples will need to visit the hospital at Day 7 and final visit.
During the ongoing COVID-19 pandemic, age was clearly the major factor of mortality. Increasing age was strongly associated with this risk, with the upper 80 years age group having more than 12-fold increased risk compared with those aged 50-59 years. Male gender was also associated with a doubling of risk. The elderly subject is particularly exposed to global denutrition with risk of micronutrients deficiencies such as vitamins and trace elements. Those deficits expose to lower immunity. In addition, viral infection as COVID-19 can also worsen these deficits. In general, low levels or intakes of micronutrients such as Zn, Se and vitamin A have been associated with adverse clinical outcomes during viral infections. This notion has been confirmed in a recent review proposing that besides vitamins A and D also B vitamins, vitamin C, omega-3 polyunsaturated fatty acids, as well as selenium, zinc and iron should be considered in the assessment of micronutrients in COVID-19 patients. In this context, the MicroCovAging study will evaluate copper, zinc and selenium, vitamin A, D and E status in elderly subjects affected by COVID- 19 and to correlate this status with prognosis of this disease.
The Sona Saliva C-19 Rapid Test is a bioassay intended for rapid point-of-care detection of the SARS-CoV-2 virus. Performance of the Sona Saliva C-19 Rapid Test assay will be assessed by comparison to a RT-PCR reference method
A cohort study included 114 adult patients with confirmed COVID-19 were categorized by BMI levels on admission: overweight (25-29.9 kg/m2), and obesity (four categories: 30-34.9 kg/m2, 35-39.9 kg/m2, 40-44.9 kg/m2, and ≥45 kg/m2).
The investigators aim to study whether education, in the form of three two-minute educational videos about COVID-19 vaccine development and dissemination, reduces vaccine hesitancy and increases intent to vaccinate. The investigators intend to use insights from this research study to develop a framework for video-based 'education prescriptions' that reduce vaccine hesitancy and increase intent to vaccinate across a number of infectious diseases. This may have wide-ranging impact: inform practice for health promotions and public health, as well as support infectious disease related work done by healthcare professionals (e.g. those working in travel medicine, where vaccination rates are also low).
This is a Pilot study for evaluating the feasibility, security and efficacy of the use of Cypropheptadine, an antihistaminic and antiserotonin drug, as an adjunct of the standardized treatment in a population of patient who are hospitalized and requiring oxygen therapy for COVID-19.
The objective of this study is to investigate the short- and long-term effects of multiple sessions of 4 mA M1 tDCS on fatigue and brain activity in recovered COVID-19 patients using established measures of perception of fatigue, performance fatigability, and cerebral glucose uptake. Our central hypothesis is that tDCS will improve fatigue short- and long-term, and thus will improve quality of life (QOL) in recovered COVID-19 patients and that these changes will be associated with alterations in brain activity.
