Filter by:There is excess accumulation of bradykinin during symptomatic SARS CoV-2 lung infection. Bradykinin causes oedema in the lung, with reduced oxygen. It also causes vasodilation, hypotension and cytokine release.
This is a randomised controlled trial conducted to prove that the immunological performance of intradermal tozinameran (i.e., Pfizer-BioNTech COVID-19 vaccine) is no worse than the standard intramuscular route in patients with immune-mediated dermatologic diseases. The side effects profile and disease activity post-vaccination will also be assessed.
With this research, we are aiming at finding out the effectiveness of prone positioning in this region population affected by moderate pneumonia due to covid 19 infection so that the hospital staff and doctors may be encouraged with facts and data to use such an easy maneuver to stabilize patient's oxygen saturation as we believe that prone positioning does have a protective effect against severe disease and has an effect on reducing mortality if patients are encouraged for prone positioning with proper technique and for suitable time duration as has been observed in the clinical practice in the covid wards. Therefore, we want to assess the effects of 8 hours per day prone positioning the patients with confirmed covid pneumonia admitted in the covid wards.
Introduction: Secondary pneumonia is frequently seen in COVID-19 cases followed up intubated, and high mortality rates can be observed. Isolation of the agent with bronchoalveolar lavage (BAL) culture or endotracheal aspirate (ETA) culture may increase the success of treatment. This study aimed to retrospectively analyze the results of BAL and ETA cultures in intubated COVID-19 cases. Methods: We routinely apply BAL culture with bronchoscopy or ETA culture within the first 48 hours after intubating. We retrospectively screened cases who underwent BAL and ETA. They were divided into two groups: Group B and E. Evaluated parameters were compared in both groups. Results: Demographic data and blood test results were similar in both groups. Intensive care unit (ICU) and intubation durations, and culture positivity were statistically significantly higher in Group B. Although not statistically significant, the mortality rate was higher in Group E. The most growth microorganisms were Candida species. Conclusion: Mortality rates were consistent with the literature. Since the microorganism isolation rate is higher with BAL and antimicrobial treatment is applied more effectively; early deaths were prevented and stay periods were prolonged. In contrast, these durations were shorter in the ETA group due to higher mortality. In intubated COVID-19 cases, a more effective treatment process can be carried out by clearing the airway with fiberoptic bronchoscopy and by specifically planning the treatment according to the BAL culture. This may have a positive effect on prognosis and mortality.
Retrospective observational cohort study. ToFCoMS: two years of follow-up of COVID-19 in MS.
The present test-negative design study aims to estimate the real-world effectiveness of Pfizer-BioNTech BNT162b2 mRNA vaccine on symptomatic SARS-CoV-2 infection and its consequences among children aged 5 to 11 years in the city of Toledo in Southern Brazil. Individuals aged 5 to 11 years who seek the public healthcare system with symptoms suggestive COVID-19 will be enrolled. Participants with a positive reverse transcriptase polymerase chain reaction (RT-PCR) test for SARS-CoV-2 will be classified as cases, and those with negative RT-PCR test for SARS-CoV-2 will be classified as controls. Cases will be followed-up for a period of 3 months by means of structured telephone interviews.
COVID-19 is an emerging pandemic disease caused by severe acute respiratory syndrome (SARS-CoV-2). Although the majority of patients infected with SARS-CoV-2 are asymptomatic or have mild symptoms, some patients develop severe symptoms that can protractedly impair their quality of life and functional capacity. SARS-CoV-2 is closely related to severe acute respiratory syndrome (SARS) with direct and indirect effects on several systems, especially the musculoskeletal system, in addition to the respiratory system. Some of these symptoms persist for a long period, called Post-Covid-19 Syndrome, directly interfering with the functional capacity and quality of life of these participants. Cardiopulmonary Rehabilitation exercises are focused on restoring functional capacity in patients affected by cardiopulmonary diseases. The primary objective of this study is to evaluate the clinical and functional effects of a quarterly Cardiopulmonary Rehabilitation exercise program for participants with post-COVID-19 syndrome. The secondary objectives will be: To compare the effects of a supervised program of 12 weeks of supervised exercises and a program of self-performed home exercises, guided by an exercise booklet, of the same duration on muscle strength and peripheral resistance; Compare the effects of a 12-week supervised exercise program and a self-performed home exercise program, guided by an exercise booklet, of the same duration on levels of fatigue and dyspnea in patients with post-COVID-19 syndrome; Compare the effects of a 12-week supervised exercise program and a self-performed home exercise program, guided by an exercise booklet, of the same duration on health-related quality of life and post-COVID-19 functional status.
The use of masks is a necessity due to the current pandemic conditions. The aim of the study is to examine the effects of the use of masks during effort on dyspnea and fatigue with hemodynamic parameters.
Background : Based on several clinical trials, eucalyptus oil can suppress edema formation and reduce inflammation, where the effect of 1,8-cineole is due to the inhibition of cytokine secretion by T lymphocytes. This but not limited to the reduction of interleukin (IL) of IL-4, IL-5, and IL-10 in nasal lavage fluids and levels of IL- 1β, IL-6, Tumor Necrosis Factor-α (TNF-α), and Interferon-γ (IFN-γ) in lung tissue of mice infected with influenza virus. Hence the researchers assume that Eucalyptus may possess benefits in COVID-19 as adjuvant therapy. Objectives : The primary objective of this study is to evaluate the efficacy of Eucalyptus oil as adjuvant therapy in mild-moderate COVID-19 patients. Hypothesis : Eucalyptus oil may reduce the inflammatory cytokines which eventually improves clinical symptoms
Vitamin D plays a pivotal but still not well understood role in the immune response to coronavirus disease (COVID-19) infection and vaccination. Many studies also showed a high negative correlation between the severity of inflammatory disease and serum 25-hydroxyvitamin D levels. Patients with acne vulgaris often had deteriorated skin condition after COVID-19 vaccination. Therefore, this study aimed to investigate the relationship of COVID-19 vaccination with serum 25-hydroxyvitamin D level and severity of acne vulgaris.
