The digital clock drawing test is feasible to administer and is highly acceptable to older adults in a preoperative setting. We demonstrated a significant association between both the dCDT time and clock score metrics, with the established 4AT. Our results provide convergent validity of the dCDT in the preoperative setting.

Changes in pulmonary hemodynamics and ventilation/perfusion were proposed as hallmarks of Coronavirus disease 2019 (COVID-19)-induced acute respiratory distress syndrome (ARDS). Inhaled nitric oxide (iNO) may overcome these issues and improve arterial oxygenation. We retrospectively analyzed arterial oxygenation and pulmonary vasoreactivity in seven COVID-19 ARDS patients receiving 20ppm iNO for 15-30minutes. The inhalation of NO significantly improved oxygenation. All patients with severe ARDS had higher partial pressures of oxygen and reduced pulmonary vascular resistance. Significant changes in pulmonary shunting were not observed. Overall, iNO could provide immediate help and delay respiratory deterioration in COVID-19-induced moderate to severe ARDS. Overall, iNO could provide immediate help and delay respiratory deterioration in COVID-19-induced moderate to severe ARDS. Hip fracture is a common, painful injury with increasing global incidence. Patients require optimal acute pain management. Systematic reviews have investigated the postoperative use of epidural analgesia and found that it may have advantages over systemic anal
