This early-stage study tested a single dose of mesenchymal stromal cells in 7 COVID-19 patients with severe acute respiratory distress syndrome (ARDS) who were on ventilators. The main goal was to check safety, looking for serious side effects like heart problems or blood clots w…

This study tested whether giving the oral polio vaccine (OPV) to adults over 50 in Guinea-Bissau could reduce their risk of getting sick or dying from COVID-19 and other infections. Researchers enrolled about 3,700 people and gave half the vaccine plus COVID-19 advice, while the …

This study tested a new way to diagnose COVID-19 using a saliva sample instead of the standard nose/throat swab. Researchers compared the new method to the usual one in 130 adults at a hospital in France. The goal was to see if the saliva test works just as well, which could make…

This study tested whether transcranial magnetic stimulation (TMS) can reduce apathy—a severe lack of motivation—in older veterans with mild cognitive impairment (MCI). About 103 participants received either real or fake TMS over 20 sessions. The goal was to see if TMS could impro…

This completed trial tested whether virtual clinics offering exercise sessions and psychological support could help cancer patients maintain physical and mental health while following COVID-19 social distancing rules. Over 1,100 adults with suspected or confirmed cancer took part…

This completed study looked at nearly 29,000 adults who had non-cardiac surgery under general anesthesia in a large Canadian health region. Researchers wanted to see how often doctors used lung protective ventilation, a technique that uses smaller breaths and gentle pressure to r…

This study looked at nearly 2,000 adults with lung cancer who caught COVID-19. Researchers tracked their health and checked for antibodies (immune system markers) right after infection and again 6 months after vaccination. The goal was to understand how lung cancer affects the bo…

This completed study looked at whether vitamin D levels in the blood are linked to how severe COVID-19 gets. Researchers measured vitamin D in 1,100 COVID-19 patients in Turkey. The goal was to see if current vitamin D thresholds reflect real clinical risk. This is an observation…

This pilot study looked at whether the COVID-19 virus can spread through the air during surgery on infected patients. Researchers took air samples and swabbed surfaces in the operating room during two surgeries. The goal was to understand contamination risks so that healthcare wo…

This completed study looked back at data from over 361,000 people hospitalized with COVID-19 in Brazil. Researchers used a public health database to describe patient characteristics and outcomes, such as death rates. They also compared the impact of vaccination on immunocompromis…

This completed study looked at 552 adults with myeloproliferative neoplasms (MPN) who also had COVID-19. Researchers wanted to see how often these patients developed blood clots, like pulmonary embolism. The goal was to understand what factors make COVID-19 worse for people with …
