Mobilizing ICU Patients May Not Affect Risk of Adverse Events, Death
Mobilizing patients who required mechanical ventilation in the intensive care unit (ICU) was associated with a less than 3% risk of adverse events such as falls, desaturation, and hemodynamic instability, a systematic review and meta-analysis found. Compared with usual care, very-low-certainty evidence showed that mobilization did not lead to adverse events (risk ratio [RR] 1.09, […]
Before Stroke Thrombectomy, Keep the Bed Flat, Trial Says
PHOENIX — For large vessel occlusion (LVO) acute ischemic stroke patients planned for mechanical thrombectomy, bed positioning made a big difference in clinical worsening, the ZODIAC trial showed. Keeping the head of the bed flat at a zero-degree angle after the CT scan while awaiting the cath lab led to 50-fold fewer cases of early […]
ECMO Therapy Out of Reach for Multiple Socioeconomic Groups
Socioeconomic disparities made certain groups on mechanical ventilation less likely to receive extracorporeal membrane oxygenation (ECMO) treatment in the years before the pandemic, a Nationwide Readmissions Database study found. Women were a relative 27% less likely to receive ECMO than their male counterparts (adjusted OR 0.73, 95% CI 0.70-0.75), while patients on Medicaid were nearly […]
Strobe light for 5G: Imaging system spotlights the tiny mechanical hearts at the core of every cellphone: Movies of minuscule vibrations reveal how well 5G and other mobile networks are operating
Inside every cellphone lies a tiny mechanical heart, beating several billion times a second. These micromechanical resonators play an essential role in cellphone communication. Buffeted by the cacophony of radio frequencies in the airwaves, these resonators select just the right frequencies for transmitting and receiving signals between mobile devices. With the growing importance of these […]
3D nano-inks push industry boundaries
Mechanical engineering researchers at Michigan Technological University have created a way to make a 3D-printable nanocomposite polymeric ink that uses carbon nanotubes (CNTs) — known for their high tensile strength and lightness. This revolutionary ink could replace epoxies — and understanding why its properties are so fantastic is a first step toward its mass use. […]
