Filter by:All consecutive patients admitted to the Polish Mother Memorial Research Institute (PMMHRI) in Lodz, Poland between 1st October 2020 and 31st December 2021 due to symptoms, which might reflect complications following COVID-19, will be included in the observational cohort study. Data concerning clinical characteristics, results of laboratory tests, other studies, such as: echocardiography, 24 hours ambulatory ECG recording will be collected. The study is planned also to be extended with the genetic predisposition in children to COVID-19 late complications (within independent grant).
This study evaluates an investigational vaccine that is designed to protect humans against infection with SARS-CoV-2, the novel coronavirus causing COVID-19 disease. The investigational vaccine, MV-014-212, is a live attenuated vaccine against respiratory syncytial virus (RSV) that is expressing the spike (S) protein of SARS-CoV-2. MV-014-212 is administered as drops or a spray in the nose. Specifically, this study analyzes the safety of, and the immune response to, the vaccine when administered to healthy adults between the ages of 18 and 69 years who are seronegative to SARS-CoV-2 and have not received a prior vaccine against COVID-19.
The SARS-CoV-2 virus is a virus newly identified in January 2020. The WHO defined COVID-19 as a health emergency of international importance. The clinical manifestation of the COVID-19 disease cannot be fully described in the short time. First insights in patients suffering from acute kidney injury (AKI) during COVID-19 indicate severe course with high mortality. The locally varying spread of SARS CoV-2 infection requires a better understanding of clinical course of COVID-19 in order to be able to establish future treatment approaches. The examination of attributable mortality and costs of COVID-19 will need to be studied on a multinational basis and therefore Kidney in COVID-19 Registry will particularly use a matched case control design.
With the unprecedented morbidity of the COVID-19 pandemic, the vaccine effectiveness needs to be assessed across diverse populations. The purpose of this study is to evaluate the safety and immunogenicity of an inactivated SARS-CoV-2 vaccine in medical workers.
This study assesses the multidimensional health status of COVID-19 survivors one-year post-infection using validated subjective and objective measures.
Background: Influenza (flu) vaccinations are required for all NIH staff members who have direct contact with patients. COVID-19 vaccines are recommended for persons 6 months of age and older. Researchers want to learn about immunity in NIH staff members who get a flu and/or COVID-19 vaccine. Objective: To understand what happens to the body s immune system throughout the year after getting the flu and/or COVID-19 vaccine. Eligibility: Adults ages 18 and older who work at NIH and plan to get the current season s flu vaccine and/or COVID-19 vaccine. Design: Participants will not get any vaccines as part of this study. Participants will be screened with a medical history and medicine review. They will get a survey via email. It will ask about their flu and SARS-CoV-2 history and vaccinations. Participants will have 12 monthly visits at NIH. If during that year they get both flu and SARS-COV-2 vaccines, their participation will be extended. Once a month, participants will be contacted. They will discuss any new medicines, recent vaccinations, or changes in medical history. Once a month, participants will have blood drawn. Once a month, participants will have nasal sampling. A small, flat absorptive strip will be placed in the nostril to soak up mucus. Participants will press against the outside of their nostril with their finger for 1 minute. Participants may be able to collect samples at home and mail them to NIH if they are not able to visit in person. Participation will last for about 12 13 months.
This cohort study aims to investigate the long-standing chemosensory disorders and oral manifestation after recovery of the COVID-19 illness. A correlation between the long-standing symptoms and the COVID-19 severity grade will be very important to understand and clarify the aetiology of these symptoms.
A new pandemic appeared in early 2020, also known as the coronavirus (Covid-19), affecting all health systems worldwide. Medical and nursing staff make every effort to treat patients resulting in physical and psychological exhaustion, which is exacerbated by the lack of medical and nursing staff, the lack of protective equipment, the increased workload, and increased shifts. In this context, the surgeons had to contribute in turn, in order to help as much as they could in dealing with this new health crisis, as a result of which they find themselves in positions that are not on their subject or in their proper training and to handle patients with a dangerous and highly aggressive respiratory infection. This brought more psychological and physical stress to the surgeons. The pandemic of Covid-19 is not known to be a purely surgical condition, but many patients with coronavirus require surgery due to an additional infection, condition, or complication. The design of this research will be observational and quantitative. Quantitative design involves the provision of numerically coded and analytical measurements, such as self-report questionnaires. The purpose of this cross-sectional research is primarily to record the levels of stress, anxiety, depressive symptoms of Greek surgeons, and their lifestyle. Secondary to correlate the stress levels with socio-demographic data and their lifestyle with other parameters of the study.
The human immune system is designed to protect individuals from external sources of infection and internal cell mutation. It works effectively and efficiently until inflammation disturbs its functioning. Once compromised by inflammation, the immune system loses its capacity to recognize antigens and dependably defend the body against disease and illness. When COVID-19 invades humans, it causes an immune-storm (cytokine-storm) that can directly damage the organ(s), leading to death. The virus is an antigen - a trigger - but it is not the actual reason that causes organ failure and death; instead, it is the body's over immune reaction that is the cause. In attempting to protect the body, the immune system overreacts to the antigen, which includes the infected cells, which causes a cytokine-storm, and the subsequent and rapid shut down of the infected individual's organ(s)' structure, leaving the body without sufficient strength or time to fight back. When the medical herbs join the body, it can slow down the immune reaction. Medical herbs benefit the physical body; they protect the cells and organism structure and mediate the immune response, allowing the T cells to kill the virus (mutated or not) internally. Such success has been achieved by the All Natural Medicine Clinic during pre-clinical trials. This clinical study's goal is to demonstrate that the immune system can be rebuilt and retrained, using natural medicine (i.e., medical herbs), to kill the virus without causing the immune storm, and to explore the mechanism by which these medical herbs, which have been used for thousands of years for healing, achieve results.
Since the beginning of the pandemic caused by SARC-CoV 2, more than 81 million cases have been diagnosed and caused around 1,7 million deaths. Currently, a drug is being sought for the treatment of coronavirus. The worldwide effort to create an effective and safe COVID-19 vaccine is beginning to yield results. Several vaccines now have been authorized around the globe; many more remain in development. Nonetheless, in the absence of effective pharmacological treatment and given the virus's transmission capacity, different alternatives have been proposed to stop the transmission of the virus. Therefore, these preventive measures against transmission are expected to remain in force for some time. The transmission of the virus occurs from person-to-person; different studies conclude that transmission occurs by aerosols from respiratory droplets. The optimal distance between people to stop person-to-person transmission is uncertain. For this reason and given that there is no effective drug, transmission prevention is of great importance especially for pandemic mitigation in community settings. The World Health Organization (WHO) established simple precautions to prevent the spread of the virus such as physical distancing, wearing a mask, keeping rooms well ventilated, avoiding crowds, cleaning your hands, and coughing into a bent elbow or tissue. For this reason, the use of the mask has been proposed in several countries, being mandatory in many of them, for use in the health environment and daily use. The WHO recommends different types of masks depending on the person, where it will be used, or the population incidence in the area. Wearing a medical /surgical mask is recommended for people over 60, those who have underlying medical conditions, feel unwell, and/or look after an ill family member. For health workers, respirator masks (such as FFP2, FFP3, N95, N99) should be used in settings where procedures are generating aerosols. The use of a mask could imply an inspiratory and expiratory restraint and generate a feeling of discomfort in many people. It is responsible for an increase in the inspiratory and expiratory pressures generated. This feeling of discomfort and the increment of pressures causes shallow and forced breathing and increases the respiratory accessory musculature activation. Person et al. observed that the subjects who used a mask felt dyspnea clinically and significantly higher than those who did not use it. However, to our knowledge, no study has analyzed the parameters of physical effort, respiratory parameters, self-perceived dyspnea, and muscle activation using different types of masks in healthy subjects. For this reason, the present study hypothesis is that there are no changes between wearing and not-wearing a mask (surgical or N-95) in the effort and ventilatory parameters, even though there may be an increase in the tone of the cervical muscles or the perception of dyspnea using a face mask. This study aims to observe the effect that the surgical mask and the N-95 mask have in the distance walked, in the oxygenometry, in the heart rate, in the sensation of dyspnea, and the tone of the inspiratory accessory muscles during the 6 minutes walking test. Procedure After verifying that the subjects meet the inclusion criteria and sign the consent, they will be given a registration number. An investigator will observe the number in a random list and included the participant in one of the three groups (without a mask, with a surgical mask, and with N95 mask). This researcher will make an initial registration of demographic data (gender, age, weight, height, cardiorespiratory pathology, smoker, number of cigarettes per day, a sport performed, hours of daily sport, and days of sport per week). Before the test, all the subjects will have to remain for 30 minutes without a mask, breathing normally. This phase will be called the resting phase. Subsequently, the subjects will go to the area where the 6MWT will be carried out. Each one of them will be performed the test according to the group to which they will be assigned. An investigator, blinded to the subsequent assessment, will encourage the participants to take the 6MWT according to the recommendations mentioned above. After performing the 6MWT, all subjects will go to the assessment area. All the subjects will wear a surgical mask so that the researcher can not know to which group they have been assigned. Besides, this researcher will not have access to the registration number or the 6-minute walking test area. At the end of each resting phase, SpO2 and baseline HR will be recorded. After every 6MWT, the HR, SpO2, and self-perceived dyspnea will be recorded. The muscle tone will also be assessed with the MyotonPRO in middle scalene and SCM. Subjects will have the option of retaking the test, going through all the phases mentioned above.
