Patients with COVID-19 frequently develop lower respiratory complications. Difficulty breathing and a low concentration of oxygen in the blood are of concern in patients with COVID-19, as they indicate that the lungs may be significantly affected. In some patients, respiratory symptoms may progress to the point where oxygen support is needed (i.e. use of an oxygen prongs, mask or ventilator). The exact mechanism of why patients with COVID-19 develop low concentrations of oxygen in blood is not fully understood. Some data suggest that the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the virus causing Coronavirus Disease 2019 (COVID-19), can affect the body's blood vessels directly and extensively. In the lung, blood vessels participate in the absorption of oxygen. Endothelin is a potent hormone produced by human blood vessels. When increased, endothelin can result in the narrowing of blood vessels in the lung and decrease the volume of blood flowing through the lungs. This decrease in in blood flow through the lungs may be one of many factors affecting normal lung function. Ambrisentan can block the effects of endothelin in the body, and this could theoretically improve blood flow through the lungs. This study will evaluate whether ambrisentan, by blocking the effects of the hormone endothelin in the lungs, improves the breathing capacity of patients with COVID-19, increases the concentration of oxygen in the blood and prevents the progression to respiratory failure and death. Ambrisentan is a drug that is currently used to treat patients with pulmonary hypertension, a disease where blood flow through the lungs is decreased. Subjects participating in this study are those patients hospitalised with severe respiratory symptoms related to COVID-19, and are considered to be at high-risk of developing respiratory complications. Ambrisentan will be administered in the hospital, and will be continued at home for up to 28 days. In this study, ambrisentan will be administered at much lower doses that those used in patients with pulmonary hypertension.
Coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). While the majority of people recover after mild symptoms, a portion of COVID-19 patients develops respiratory failure. Coagulopathy and thromboembolism are prevalent in severe COVID-19, and these factors are associated with decreased survival. Coagulation is an intricate balance between clot promoting and dissolving processes in which vitamin K plays an essential role. Elastin is a major component of dynamic tissues such as lungs and arteries, and elastin calcification stimulates elastin degradation and vice versa. The vitamin K-dependent Matrix Gla Protein (MGP) protects elastin from both calcification and degradation. Although technically feasible, direct quantification of blood vitamin K levels is not an appropriate method to assess overall vitamin K status due to differences in bioavailability and half-life time between the two naturally occurring vitamin K forms (vitamin K1 and K2). Measuring inactive levels of vitamin K-dependent proteins in the circulation is the method recommended by most experts, as it represents the systemic availability of both vitamin K1 and K2. Dp-uc (dephospho uncarboxylated, i.e. inactive) MGP and proteins induced by vitamin K absence (PIVKA-II) both inversely correlate with vitamin K status and can be used as surrogate markers of total vitamin K status. Recently, we found a severely reduced vitamin K status (as quantified by dp-ucMGP) in COVID-19 patients compared to controls. In COVID-19 patients, low vitamin K status was also associated with poor outcome (defined as the need for invasive ventilation or death), accelerated elastin degradation (quantified by plasma (iso)desmosine (DES) a byproduct of elastin degradation). Based on these finding and previous studies, we hypothesize that improving vitamin K-status by vitamin K supplementation could have favorable effects on pulmonary damage and coagulopathy in COVID-19.
This study is to evaluate the safety, efficacy and pharmacokinetics profile of human monoclonal antibodies, BRII-196 and BRII-198 compared with placebo in patients with COVID-19.
This study aims to explore whether quarantine measures, social distancing and hospital containment policies among women giving birth during the COVID-19 pandemic enhanced psycho-emotional distress in the immediate postpartum period. The investigators tested for depression using the Edinburgh Postnatal Depression Scale (EPDS) in the first 6 postpartum months, and then used the Fear of COVID-19 Scale, measuring also the adherence and practices of breastfeeding according to WHO.
This study aims to understand the comparative effectiveness of two PSH models (PB-PSH and SS-PSH) on quality of life and COVID-19 related health behaviors by following for 6 months a cohort of 800 PEH who have been placed in either PB (n=400) or SS (n=400). In a natural observational experiment, participants will complete 6 monthly mobile-based questionnaires exploring quality of life including physical, mental, social, and housing/environmental health, COVID-19 prevention practices (i.e., handwashing, social distancing, face covering), and past-30-day healthcare utilization. A sub-sample of 40 participants living in both PB-PSH and SS-PSH will be qualitatively interviewed longitudinally to help contextualize quantitative findings. Focus groups will also be conducted with providers of PSH and qualitative interviews will be conducted with other key stakeholders to understand perspectives on the challenges of implementing and sustaining COVID-19 related prevention practices while maintaining a continuity of care.
University students report high levels of stress, anxiety and depression every year, which, according to some research, responsible for university administration and popular media, constitutes a global crisis of mental health of students at these levels. Exposure to academic stress directly compromises students' motivation and attitudes towards learning. High levels of perceived distress in the face of inadequate resources to deal with the situation leaves people at risk of developing major psychiatric problems, especially when this distress is prolonged or severe.
Pathogen-free, concentrated, pooled convalescent plasma has higher SARS-CoV2 antibody titers and neutralizing antibody activities, without requiring blood group compatibility that allows patient accessibility in a shorter time and has safe plasma characteristic.
The purpose of this study is to characterize functional status and physical activity of patients with COVID-19 after hospital discharge.
prospective multicenter study The main aim is to study the impact of maternal COVID-19 on breast milk immune, microbiological, and metabolic profile and infant growth and development
