Filter by:This is a Phase IIb, open-label, uncontrolled, multi-centre, non-inferiority clinical trial, to assess the safety and immunogenicity of BIMERVAX® as a heterologous booster dose in adolescents. In this study a total of 300 adolescents from 12 to less than 18 years will be enrolled and followed for 12 months.
The lung is the organ most affected by COVID-19. There are patients who successfully overcome the acute COVID-19 infection and their lungs return to a normal state. However, a significant number present dyspnea and fatigue as sequelae without having a pulmonary origin, but with a significant impact on functionality. In our published studies in relation to fatigue in patients with symptoms attributed to persistent COVID, the investigators have shown that there is muscle involvement, observing a decrease in mechanical efficiency. This muscle involvement causes stimulation of ventilation through the ergoreceptors, causing ineffective ventilation. This affectation can be explained by the findings obtained in the muscle biopsies that the investigators have performed, where the investigators observed a splitting of the basement membrane of the capillaries causing an alteration in the diffusion of metabolic substrates and oxygen. The main objective of our project is to be able to observe the response in ventilatory efficiency in patients with symptoms of post-covid fatigue after ingesting beet juice.
This cross-over study will assess a no added sugar diet, a restricted daily eating window, and one or two full day water fasts to determine if there is an effect on self-reported symptoms of Long Covid (PASC).
The novel coronavirus SARS-CoV-2 infection, COVID, continues to rage throughout the world with 115,000,000 confirmed cases and over 2,500,000 deaths (as of Mar 3, 2021). This translates to millions of people surviving COVID19 infection. While the lungs are ground zero, COVID tears through organ systems from brain to blood vessels. We are now beginning to see people recover but complain of ongoing problems, including lingering cognitive problems, depression, and anxiety. We have brought together 2 laboratories with complementary techniques including psychological testing and neuroimaging methods togethers with markers in the blood that may signal damage in the brain. A close look at these problems is timely and imperative if we are to understand the pathophysiology of 'COVID brain' and prepare for downstream problems.
This is a pilot non-randomized-controlled trial to evaluate the impact of "Tomando control de su salud", an evidenced-based intervention for chronic disease self-management in the quality of life of patients living with Long-COVID in Puerto Rico.
The goal of this decentralized, observational study is to enroll and observe adults in the contingent United States during the 2023-2024 flu season. The main study objectives are to create a dataset of paired wearable data, self-reported symptoms, and respiratory viral infection (RVI) from PCR testing during the 2023-2024 flu season and to develop algorithm that is able to accurately classify asymptomatic and symptomatic RVI and understand the algorithm's performance metrics.
This study is a randomized, double-blind, placebo controlled clinical exploratory study to evaluate the safety, tolerability and immunogenicity of TI-0010 vaccine in healthy adults aged 18-59. TI-0010 was manufactured by Therorna Inc. TI-0010 is a novel lipid nanoparticles (LNP) -encapsulated circRNA-based vaccine targeting RBD of SARS-CoV-2. Up to one hundred subjects will be enrolled into one of 4 cohorts. Low-dose(Dose Level 1) is for Cohort 1 and Cohort 2 , and the high dose (Dose Level 2) for Cohort 3 and Cohort 4. Cohort 1 and Cohort 3 receive 2 doses (with a 28 day interval) via intramuscular injection respectively, and Cohort 2 and Cohort 4 receive 1 dose via intramuscular injection respectively. Participants are randomized to receive TI-0010 or placebo in a 4:1 ratio.
The goal of this pilot study is to assess the feasibility and impact of using sodium citrate nasal spray as an adjunct to olfactory retraining in participants with long-term post-COVID-19 olfactory dysfunction. The main questions it aims to answer are: - Is sodium citrate nasal spray in addition to smell retraining feasible for participants to use in terms of participant need/desire, adherence, and adverse events? - Does sodium citrate nasal spray in addition to smell retraining further improve smell as compared to normal saline spray and smell retraining? Participants will: - Provide consent for enrollment. - Undergo smell testing via Sniffin' Sticks. - Use a nasal spray (either sodium citrate or normal saline) followed by olfactory retraining twice a day for 12 weeks. - Return for follow-up Sniffin' Sticks testing. Researchers will compare the sodium citrate group and the normal saline group to determine differences in smell improvement.
The goal of this observational study is to learn about the correlation between COVID-19 and hyperthyroidism in Patients with hyperthyroidism complicated with COVID-19. The main questions it aims to answer areļ¼ - Changes of hyperthyroidism in HT patients complicated with COVID-19 - Changes of anxiety and depression in hyperthyroidism patients before and after SARS-CoV-2 infection. Participants will have regular follow-up visits to hyperthyroidism in our hospital, and the investigators will collect the thyroid function and related examination indexes of patients in the corresponding time period.
Since December 2019, a new coronavirus, SARS-CoV-2, has been identified in the city of Wuhan in Hubei province in China and is the cause of a global pandemic. This highly contagious virus is responsible for the COVID-19 disease, the manifestations of which can range from a simple flu-like syndrome to acute respiratory distress syndrome (ARDS). Transmission of SARS-CoV-2 is mainly linked to droplets. The mode of transmission of SARS-CoV-2 involves at least droplet-type isolation for caregivers with wearing a surgical mask and extended contact type (overcoats, caps, gloves). During procedures with a high risk of aerosolization of viral particles (intubation, aerosols, aspirations, nasopharyngeal swabs), wearing an FFP2 mask and protective glasses are recommended. In addition, oxygen therapy, particularly at a flow rate greater than 6 L/min, could also lead to airborne contamination. The occupational risk of contamination of health professionals is well identified, particularly in Chinese but also Italian studies. In Italy, 20% of healthcare workers have been contaminated. In China, a rate of 3.5 to 29% in Wuhan hospitals has been identified. Among the professionals exposed within the hospital, those in emergency services are part of the category with the greatest risk of contamination along with those in intensive care units. Recommendations from experts from the French intensive care society and foreign companies made it possible to identify the situations most at risk of contamination. In addition, the organization has made it possible to better understand patient care circuits in order to limit the risks of contamination. However, procedural errors may exist, implying the need for frequent training sessions for professionals. In addition, if the recommendations specify the need to obtain negative pressure in the rooms or at least zero, the material limits linked to reception in emergency departments with the need for intubation of a significant number of patients sometimes makes it difficult to carry out these risky actions under optimal conditions. Finally, the methods of sorting suspected cases to organize care in areas different from other emergency patients do not prevent assignment errors, a source of contamination for caregivers and patients. Thus, health professionals are among the priority people to be screened in accordance with the recommendations of the High Authority of Health. Indeed, even if symptomatic healthcare workers were mostly screened at least by taking a nasopharyngeal swab, some healthcare workers were able to develop immunity to the disease without having been symptomatic. The number of asymptomatic cases of COVID-19 is significant, but the proportion is not yet clearly identified. In addition, massive screening of symptomatic and non-symptomatic healthcare workers would make it possible to reduce the number of nososcomial contamination. Determining the serological status of healthcare workers is a priority, particularly in services on the front line of caring for patients with COVID-19, such as emergency structures.
