Association of intermittent and constant #knee pain patterns with knee pain severity, radiographic knee #osteoarthritis duration and severity

..Intermittent and Constant OA Pain (ICOAP) scores were characterized as 1) no intermittent or constant pain; 2) intermittent pain only; 3) constant pain only; and 4) a combination of constant and intermittent pain. Knee pain severity was assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale and the Visual Analog Scale (VAS).

Effectiveness of Surgical and Cotton #Masks in Blocking SARS–CoV-2: A Controlled Comparison in 4 Patients

..Neither surgical nor cotton masks effectively filtered SARS–CoV-2 during coughs by infected patients. Prior evidence that surgical masks effectively filtered influenza virus (1) informed recommendations that patients with confirmed or suspected COVID-19 should wear face masks to prevent transmission (2). However, the size and concentrations of SARS–CoV-2 in aerosols generated during coughing are unknown. Oberg and Brousseau (3) demonstrated that surgical masks did not exhibit … Continue reading Effectiveness of Surgical and Cotton #Masks in Blocking SARS–CoV-2: A Controlled Comparison in 4 Patients
