Filter by:The various epidemics that health systems periodically suffers require having valid and detailed information on its evolution and predictions in the short, medium and long term in real time to allow the health system to organize itself in advance to be able to address the health and sanitary problem that this entails.The objectives of this proposal are: to study the usefulness of the health system's information and data storage system as a source for quickly and efficiently obtaining data necessary for modeling an epidemiological outbreak; its modeling in order to predict its evolution and the presentation of results to help in decision making. The investigatorswill rely on the experience obtained so far during the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, to define semi-automatic and flexible criteria for searching, extracting, cleaning and aggregating data. Predictions of incidence, number of hospital and ICU admissions, and number of deaths will be made at the Basque Country level.Within the analysis of temporal data, especially in the context of the pandemic, it is essential to have robust tools that allow accurate predictions. In this study, the investigators employed P-splines based on the negative binomial distribution to predict pandemic-related positive cases, hospital admissions, and ICU admissions.
Safety, reactogenicity and immunogenicity study of the vector vaccine GamCovidVac for the prevention of coronavirus (COVID-19) infection caused by the SARS-CoV-2 virus with altered antigenic profile with participation of adult volunteers
Safety, reactogenicity and immunogenicity study of the vector vaccine GamCovidVac-M for the prevention of coronavirus (COVID-19) infection caused by the SARS-CoV-2 virus with altered antigenic composition with participation of 12-17 years old volunteers.
The purpose of this research study is to find out how well two different 2023-2024 updated COVID-19 vaccines protect people from COVID-19 (the disease caused by the SARS-CoV-2 virus), and to determine if getting a 2023-2024 updated vaccine provides better protection from COVID-19 than not getting a vaccine. If the participant chooses to get a 2023-2024 updated COVID-19 vaccine as part of this study, they will have a 50/50 chance of receiving either the Novavax or Pfizer mRNA vaccine. If the participant decides not to get a 2023-2024 updated COVID-19 vaccine, the participant can still participate in other study activities. STUDY ACTIVITIES: - An online enrollment survey - An in-person enrollment visit - Weekly online surveys for 20 weeks - Weekly COVID-19 tests for 20 weeks - Additional online surveys if you have COVID-19 symptoms or tested positive for COVID-19. - Additional COVID-19 tests if you have COVID-19 symptoms or tested positive. - Online survey questions in the middle and at the end of the study
The COVID-19 pandemic severely impacted the medical system both directly but also through incomplete recovery from the virus in the form of post-acute sequelae of COVID-19 (PASC). PASC affects at least 9.6 million individuals as of May 2022 and continues to affect many more. PASC is a multisystem disorder often presenting with mental fog, dyspnea on exertion, and fatigue among other symptoms. The etiology of PASC is uncertain but theories include direct cytotoxicity, dysregulated immune responses, endotheliitis associated with microthrombi, eNOS uncoupling, and myocardial fibrosis with impaired ventricular compliance. To date, there are no established treatments. Exercise has the potential as a therapeutic option to improve VO2peak and improve each of the aforementioned underlying etiologies. The investigators plan to examine the effect of High-Intensity Interval Training (HIIT) and Moderate intensity exercise training (MOD) on the symptoms and exercise tolerance of patients with PASC. The investigators approach will consist of a randomized, blinded, 2-arm, parallel-group design. Enrolled subjects will be randomly assigned to one of two groups in a 1:1 allocation ratio. All groups will undergo a 4-week intervention of 3 days of HIIT per week and 2 days of MOD per week or control of light stretching and controlled breathing. Subjects will be assessed before and after the 4-week intervention to examine the extent to which 4 weeks of the HIIT and MOD combination improves VO2peak and left ventricular diastolic function, global longitudinal strain (GLS), and global circumferential strain (GCS). Further, the investigators will explore changes in markers such as heart rate, heart rhythm, blood pressure, quality of life, exercise tolerance, and PASC symptoms as well as blood/serum markers.
This is a first in human clinical study to evaluate the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of RQ-01. Adult patients who have tested positive for SARS-CoV-2 virus, have mild symptom(s) of COVID-19 disease, and who are at low risk for developing moderate or severe COVID-19 disease are welcome to participate. The main questions this study aims to answer are: 1. What is the safety profile of RQ-01? 2. What is the reduction in SARS-CoV-2 ribonucleic acid (RNA) shedding after administration of RQ-01? 3. How effective is RQ-01 versus placebo in reducing COVID-19 symptoms? After providing informed consent, subjects will be randomized to RQ-01 (high or low dose) or placebo and will be dosed for 3 consecutive days. Throughout the duration of the trial, subjects will participate in the following activities: perform rapid antigen and polymerase chain reaction (PCR) tests for COVID-19, answer questions about their medical history and medications, answer questions about their COVID-19 history and symptoms, conduct a physical exam, have their vitals measured, and have bloodwork done.
AZD3152, a single mAb, is being developed to have broad neutralizing activity across known SARS-CoV-2 variants of concern for pre-exposure prophylaxis of COVID-19. The aim of the Phase II study is to evaluate the safety, neutralizing activity and efficacy of AZD3152 for pre exposure prophylaxis of COVID-19
Safety, reactogenicity and immunogenicity study of the drug "Sputnik Lite" for the prevention of coronavirus infection caused by the SARS-CoV-2 virus with altered antigenic composition with participation of adult volunteers.
This study will look at the effects of amantadine on cognitive function in persons with Long COVID. It will also collect specimens to study possible causes of cognitive symptoms in Long COVID, and whether any lab tests can predict who will respond better to amantadine.
