Filter by:The purpose of this research study is to evaluate and improve a rapid COVID-19 test. The test is designed to identify people who are most contagious and likely to spread the virus to others. This test will be performed at various locations in the Madison area using a mobile laboratory or standard lab space for processing. Saliva samples can be collected and processed at these locations or participants can self-collect at home and drop their samples off at designated locations for same day processing. Results of potential findings of clinical significance will be communicated to the participants by a physician with appropriate expertise on the study team. Individuals with a potential finding of clinical significance will be encouraged to self-isolate and obtain a diagnostic test at their earliest convenience. No results will be given if the test is negative. If the participant consents, advanced molecular testing such as PCR or viral sequencing can be done and results can be shared via online databases, presentations and publications along with the date, site and county of collection to help facilitate tracking the spread of the virus.
Overall mortality of COVID-19 is variable and has been reported to be between less than 1% and 7%. Many authors around the world also reported data on hospitalization rate, need for intensive care unit (ICU) care and need for mechanical ventilation in SARS-CoV-2 infected patients. To provide anesthetic and surgical care to SARS-CoV-2 infected patients, many health workers have to organize surgical platforms, personal protections and in-hospital trajectories to prevent dissemination and cross-contamination. However, no data has been published on the surgical need of these patients, their postoperative outcomes and the impact they may have on the operating room. Postoperative outcomes in SARS-CoV-2 infected patients seem to be variable. Expected benefits from a surgical procedure may be different in this population if their postoperative mortality is higher than expected. The association between preoperative characteristics and postoperative outcomes in this population has to be better defined. There is a need to better quantify these and better inform use of surgical resources during a pandemic. To address this knowledge gap, the investigators propose to conduct a multicenter observational cohort study in SARS-CoV-2 infected patients undergoing a surgical procedure, as well as in those who have recovered from COVID-19.
Novel Coronavirus (2019nCoV) or Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) that causes Coronavirus Disease 2019, or known as Covid-19 has recently become a global health emergency since it was first detected in Wuhan, the People Republic of China in December 2019. Since then, the prevalence has rapidly increased worldwide. In Indonesia, by the end of April 2020, around 10,000 patients have been tested positive for Covid-19 infection, with a case fatality rate of around 8%. The pathogenesis of Covid-19 is still under investigation and to our understanding, ACE2 receptors in the alveoli serve as the binding site of the S-protein of envelope spike virus of SARS-CoV-2. TMPRSS2 enzyme aids the fusion between cell membrane and capsid of the virus, allowing penetration of virus into the cell. Vesicles containing virion fuse with cell membrane and released as new virions. Cytopathic effect of the virus and its ability to overcome immune response determines the degree of infection. Differences in immunological profile among degrees of severity of Covid-19 may vary especially for the number of pro-inflammatory cytokines such as tumor necrosis factor alpha (TNF-α), interleukin (IL)-1, IL-6, IL-8, leukemia-inhibiting factors (LIF), immunological markers such as CXCR3+CD4+, CXCR3+CD8+ T cell and CXCR3+ NK cells, implying the ongoing cytokine storm. The previous studies also found increasing number for infection markers such as procalcitonin, ferritin, and C-reactive protein. The decreasing number of anti-inflammatory cytokines in such as IL-10 also supports this finding. Previous studies have shown immunomodulating and anti-inflammatory capacity of the mesenchymal stem cells (MSCs). MSCs contributed to the shifting of pro-inflammatory Th2 into anti-inflammatory Th2. One of the most recent study on the usage of MSCs on Covid-19 patients showed increased expression of leukemia inhibitory factor (LIF), which give rise to inhibitory effect of T lymphocyte and natural killer (NK) cell population. Vascular epithelial growth factor (VEGF) is found increasing following MSCs administration, which indicates the ability to improve the disrupted capillaries due to SARS-Cov-2 infection. The ability of MSCs in differentiating to alveolar cells is proven by the presence of SPM and SPC2, surfactant proteins produced by type II alveolar cells. MSCs are unable to be infected by SARS-CoV-2 since they don't have ACE2 receptors and TMPRSS2 enzyme.
Approximately 15% of patients with SARS-CoV-2 infection / COVID-19 develop a severe clinical course. This leads to hospitalization and potentially life threatening complications such as pneumonia and respiratory failure. Predictors for early detection and risk stratification are urgently needed. Moreover, only scarce information is available for long-term follow-up and late complications associated with infection. We therefore aimed to find predictors for severe courses of the novel disease as well as to establish strategies for therapeutic monitoring and follow-up.
The Canadian Paediatric Society recommends breastfeeding during COVID-19 infection. Human milk is the best form of infant nutrition providing significant protection against many illnesses for term and preterm infants. When mothers of hospitalized infants are unable to supply their milk, the recommended supplement is human donor milk. The impact of a pandemic on human milk banking is unknown. This study seeks to address this public health issue. Donor milk will be collected from the Rogers Hixon Ontario Human Milk Bank at Sinai Health System in Toronto. Samples will be analyzed for the COVID-19 virus specific nucleic acid and antibody in real-time and results will be immediately disseminated to relevant organizations to inform local, national and international guidelines surrounding donor milk banking to protect the health of infants.

SAR-Cov-2 infection and its clinical manifestation known as COVID-19 beside the respiratory and lung involvement may include the cardiovascular system, the nervous system and the liver. In the acute phase of the disease, all of these conditions may be life-threatened. As a result, after the acute phase of COVID-19, early complications may be observed, including heart, lungs, brain, muscles and liver. A few papers to date have been reported of myocarditis, ventricular arrhythmias, post-inflammatory changes in the lung and liver, as well as ischemic changes in the brain, diseases of skeletal muscle, which may have adverse prognostic effects. Due to the extent of the pandemic, the severity of the complications and the expected high complications' prevalence in the early post-recovery period, a study was designed to determine the extent of the problem of early complications after COVID-19. Complex cardiological, pulmonary, neurological and hepatological diagnostics are planned, including laboratory, imaging and functional tests. The results obtained, in addition to determining the scale of the problem, will allow the selection of studies that optimally identify patients with early complications. The purpose of this procedure is to enable rapid treatment of diseases that are complications of SARS-COV-2 infection. An additional aspect raised in the project will be the issue of psychiatric disorders (anxiety, depression, post traumatic disorders). The main three purposes of the study include: 1. the assessment of prevalence of particular complications after COVID-19. 2. identification of the demographic and clinical risk factors of COVID-19 complications 3. determining the diagnostic tests which are sufficient to detect early complications of COVID-19
The purpose of this study is to assess the efficacy of RUTI® vaccine preventing SARS-CoV-2 infection (COVID-19) in healthcare workers.
As coronavirus disease 2019 (COVID-19) spreads across the world, the intensive care unit (ICU) community must prepare for the challenges associated with this pandemic. Providing an efficient care to the patients of the most severely affected category - intensive care unit (ICU) patients - has become one of the serious problems appearing in the COVID-19 pandemics. A typical patient's clinical portrait in ICU of COVID centers is very similar in different countries, however, the key to improve the treatment results for critically ill patients has not yet been found. Data on predictors of severe course in COVID-19 is limited. Knowledge of predictors of severe course of disease can lead to different selection of therapeutic strategy, determine the group of risk of patients for severe course of disease, and improve outcomes.
This study is intended to explore the possible protective role of anti-androgens in SARS-CoV-2 infection
