Filter by:The investigators will randomise individuals from family doctors' lists of patients that are at risk of severe Coronavirus Disease 2019 (COVID-19), and that are not registered as having taken the vaccine against the disease. The patients will be randomised to receiving a phone call from their family physician where the participants are given the opportunity to raise questions they might have around vaccination. The investigators will assess whether this has an impact on vaccine uptake.
Aims are to assess periodontal health and salivary stress/ immunity responses in COVID-19 survivors
Acute coronavirus disease 2019 (COVID-19) infection can include cardiac and pulmonary manifestations as well as post-infectious complications such as multisystem inflammatory syndrome (MIS-C), also known as pediatric inflammatory multisystem syndrome (PIMS / PIMS-TS). The precise etiology for COVID-19 symptoms and MIS-C is still obscure but there is evidence that endothelial damage may play a role. At recovery, symptoms such as dyspnea, fatigue, weakness, myalgia, chest pain and palpitations are prevalent. Data regarding functional capacity, cardiopulmonary and vascular function post COVID-19 infection are scarce. To the best of our knowledge, few studies has evaluated functional capacity of patients recovering from COVID-19 infection and complications using cardiopulmonary exercise testing (CPET), and no study included endothelial function assessment. Aims I. To investigate the effect of COVID-19 infection on cardiovascular and pulmonary function and exercise parameters in the pediatric and adult population. II. To investigate the effect of PIMS on endothelial function in pediatric population. Research hypothesis: 1. After COVID-19 infection, aerobic function is impaired due to cardiac and/or pulmonary limitation 2. Endothelial function in children after PIMS is impaired in comparison to healthy individuals and to patients after COVID infection with mild symptoms. Importance of the study: Cardiovascular and pulmonary assessment of patients recovering from COVID-19 infection using CPET and Peripheral Arterial Tonography (EndoPATâ„¢) has not been reported previously, and will provide new insights into the long term significance of COVID-19 infection.
Patients infected with Covid 19 suffer from frequent pain (headache, migraines, joint pain, muscle pain) in the acute phase which may persist after a stay in intensive care or in an intensive care unit, in the event of post-traumatic stress syndrome, pre-existing comorbidities. The pain mechanisms observed during the covid epidemic are nociceptive / inflammatory pain, neuropathic pain, and nociplastic pain. Auricular transcutaneous vagus nerve stimulation (tVNS) is a promising therapeutic strategy that may reduce inflammation and pain level. Colosat is a prospective non-randomized pilot feasibility study. Colosat is a 8 weeks non randomized trial investigating the painful Covid long. tVNS will be performed using a transcutaneous lectrical nerve stimulation (TENS) device connected to an auricular electrode stimulating the cutaneous area of the left ear innervated by the auricular ascendant branch of the vagus nerve.
This is a cross-sectional research. The investigators plan to recruit about 250 front-line nurses who provided direct care to COVID-19 confirmed cases in a medical center in Taiwan. Online querstionnaires are used to collect the data. The relationship between variables such as stressors related to COVID-19, coping status, resilience, and compassion fatigue of participants will be analysis to provide the direction of nurses' mental health-related interventions.
The aim of our study is to investigate the effectiveness of telehealth exercise training programs in Post-COVID patients.
Study objectives: To evaluate the immunogenicity and immunity persistence and safety of recombinant novel coronavirus vaccine (CHO cells) after booster immunization in populations vaccinated with two doses of marketed novel coronavirus inactivated vaccine (BBIBP-CorV). Study method: For the subjects who have been vaccinated with two doses (the interval between two doses ≥ 3 weeks) of the novel coronavirus inactivated vaccine (BBIBP-CorV) for 3 to 9 months, 1 dose of the recombinant novel coronavirus vaccine (CHO cells) was administered. Blood samples were collected before booster immunization, 14 days, 30 days and 180 days after booster immunization for neutralizing antibody detection. All AEs were collected within 1 month after the booster immunization. All SAEs were collected within 6 months after the booster immunization.
Previous studies should that patients with chronic liver diseases, cirrhosis, hepatocellular carcinoma and post-liver-trasplant status had lower immunological response to SARS-CoV-2 vaccines than healthy population. Along with the waning of antibody and emerging SARS-CoV-2 variants, a third dose SARS-CoV-2 booster vaccination is now considered as an effective strategy. Previous studies showed good safety and immunogenicity of the SARS-CoV-2 booster vaccination in healthy population. However, the relevant information in patients with liver diseases need further research. This study (NMCID-CHESS 2201) aimed to investigate the safety and immunogenicity of the SARS-CoV-2 booster vaccination in population with chronic liver diseases
Coronavirus-induced disease 2019 (COVID-19) is an infection caused by a virus whose full name is severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This is a new and rapidly-spreading infectious disease which carries a significant risk of death, has brought massive economic impact globally and has proved hard to contain through public health measures. While we currently have effective vaccines, they do not protect the whole community and the constant threat of new mutations means there is an urgent need to identify new approaches to reducing community spread of infection. Heparin is a naturally occurring sugar molecule which has been used for a century to treat a range of medical problems including heart attacks, strokes, and blood clots. It has also been investigated as a treatment for pneumonias. Recent research suggests it binds to the SARS-CoV-2 virus in such a way it may reduce the virus' ability to enter cells. This may be an important way to tackle the early stages of infection which occurs inside the nose. Therefore, this medication could be used amongst people with early COVID-19 infection and amongst their household contacts to reduce the rate of virus transmission during local outbreaks. If proven effective there are many other potential uses as primary prophylaxis for people working in high risk areas, for travel, for protection in high risk crowded environments such as nightclubs, or sporting events. Heparin is safe, inexpensive, available worldwide and if effective could be rapidly used across the world to slow progression of the current pandemic. Further there are recent studies suggesting that the risk of brain complications as part of "long COVID", are directly related to the amount of virus in the nose. Reducing the viral load in the nose is thought to be effective in reducing these "long COVID" complications. This study will explore the effect of the intervention on viral load and long COVID. In this study, researchers want to investigate this medicine in people who have been identified by a COVID-19 swab test to be in the early stages of infection(defined as the index case), and amongst their household contacts. Each participant would take the medicine or a dummy control solution by spray into their nose three times a day for 10 days. The study will investigate if there are fewer people who contract SARS-CoV-2 infection by day 10 amongst households who receive the medicine than households which receive the dummy control.
Patients infected with covid-19 have a series of clinical manifestations, including fever, cough, myalgia or fatigue, dyspnea, even acute respiratory distress syndrome (ARDS), acute cardiac injury and secondary infection, and a lot of sever patients had to been admitted to the intensive care unit (ICU) One of the hallmark of COVID 19 is the cytokine storm that provokes primarily pneumonia followed by systemic inflammation. besides the positive viral nucleic acid analysis and the representative pulmonary CT findings (bilateral distribution of patchy shadows and ground glass opacity), most individual patients showed the changes in several immunological and biological markers . CD177 which is one of the most clinically important neutrophil alloantigen because: i) it is a neutrophil-specific marker representative of neutrophil activation, ii) it was the most highly differentiated expressed gene in patients, and iii) the protein can be measured in the serum, making its use as a marker clinically applicable. It is expressed on neutrophils, neutrophilic metamyelocytes, and myelocytes . Given the contribution of the neutrophil activation pathway in the clustering of COVID-19 patients, neutrophil-activation features that could act as possible reliable markers of disease evolution.
