Filter by: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.
This is a prospective, multicentre study in which the accuracy of the Molbio Diagnostics Truenat™ MTB (Mycobacterium tuberculosis) Plus/COVID-19multiplex will be assessed for TB and COVID-19 case detection using prospectively collected NP swabs and sputum samples from patients with symptoms suggestive of TB. The overall study period is of 24 months which includes telephonic follow-up of the baseline COVID-19negative patients at 2 weeks and of all participants at 2 months.
The effectiveness of COVID-19 vaccines in reducing the risk of severe COVID-19 is currently demonstrated. In France, since the beginning of the vaccination campaign, 54,266,859 people have received at least one injection (ie. 80.5% of the total population), 53,354,698 people now have a complete vaccination schedule (ie. 79.1% of the total population) and since the beginning of the booster campaign, 39,558,416 people have received a 1st booster dose. However, the data currently available on the persistence of immunity on the one hand, and the appearance of viral variants with reduced sensitivity to vaccine immunity on the other, suggest the need to administer booster doses at variable intervals depending on age and comorbidities. Real-life efficacy data from France and around the World confirm that people who have received a booster dose are better protected than those who have only received a primary vaccination schedule (HAS). In this context, the Ministry of Health, has pronounced on the possibility of administering a second booster dose for people aged 60 and over. Moreover, the recommendations for the Haute Autorité de Santé for the 2nd booster dose in general population should be available in June 2022. Three vaccines, mRNA BNT162b2 vaccine, Sanofi/GSK monovalent D614 and B.1.351 formulations were administered as 1st booster in the CoviBOOST trial. All three vaccines boosted antibodies and neutralizing response after a BNT162b2 initial course. Heterologous boosting with the Sanofi/GSK SARS-CoV-2 recombinant adjuvanted protein vaccine B.1.351 (Beta formulation) provided higher rates of neutralizing antibodies against variants, including Omicron BA.1, compared with the mRNA BNT162b2 vaccine. Due to the start of the study after the beginning of booster vaccination campaign in elderly, the enrollment of participants over 65 years of age was difficult so, only 8 subjects aged 60 years and over were enrolled. As vaccine immunogenicity is lower in older populations and is waning more rapidly, it is important to evaluate the adjuvanted vaccine in this population. The objective of this ancillary study is to compare, in participants aged of 60 years and older and previously vaccinated with 3 doses of mRNA vaccine (2 doses of Pfizer BioNTech) and a 3rd dose of Pfizer BioNTech or Moderna, the immunogenicity of a second booster dose of the B.1.351 strain recombinant protein- based subunit vaccine to BNT162b2 (mRNA Pfizer BioNTech Vaccine).These results will provide important information for booster vaccination recommendations in this age group.
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.
Rationale: In patients with COVID-19 admitted to the hospital, large heterogeneity exists in patients, timing and dosing of steroid therapy. It is unclear how to treat patients who fail dexamethasone therapy. High-dose steroids are prescribed mainly in patients with the most severe disease, which may be too late given the potential escalation of pathophysiological pathways in these patients. Objectives: The main objective is to determine the most optimal form, timing and dosing of steroid therapy to reduce the morbidity and mortality of patients admitted to the hospital for COVID-19. This objective will be addressed in 4 work packages (WP): - WP-1A-ward admission: What is the effect of higher dose steroids upon hospital admission on clinical deterioration and what would be the optimal timing of increasing steroid dosage? - WP1B-ward late: Do high-dose steroids, compared to no steroids, improve outcomes in dexamethasone-unresponsive COVID-19 patients on the ward after dexamethasone 6 mg/day for 10 days? - WP2-ICU admission: Do high-dose steroids, compared to 6 mg/day dexamethasone or its equivalent, improve outcomes in patients admitted to the ICU with moderate/severe C-ARDS? - WP3-ICU late: Do high-dose steroids, compared to no steroids, improve outcomes in ICU patients with moderate/severe C-ARDS after dexamethasone 6 mg/day for 10 days? - WP4-biobank: Can biomarkers help predict outcomes after (high dosed) steroid therapy? Study design: Retrospective observational multicenter study in the Netherlands. Study population: Adult patients (≥ 18 years) hospitalized with COVID-19 will be included, more specifically: Intervention (if applicable): Not applicable (retrospective study design). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Given the retrospective nature of the study, no burden, risks or benefits for the patient are associated with participation. The target population of this study is specific to hospitalized patients with COVID-19.
Prospective study that will evaluate the clinical agreement of the CoviDx™ Self test compared to SARS-CoV-2 RT-PCR.
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.
Loss of the sense of smell is a characteristic feature of COVID-19 and likely related to viral invasion of the olfactory mucosa but is also a prodromal feature of PD. This constellation has kindled concerns that COVID-19 - similar to the Spanish Flu Pandemic in 1918 - might trigger a second wave of post-infectious parkinsonism. The main objective of the study is to probe for the presence of pathological α-synuclein assemblies in the olfactory mucosa of patients with COVID-19.
