Using Recent Diagnostic Scans Can Substantially Cut Time to Treatment for Patients Needing Urgent Palliation

Imaging Technology

milla1cf Tue, 10/03/2023 - 11:11 October 3, 2023 — Using previously taken diagnostic computed tomography (CT) scans in place of CT simulation scans to plan simple palliative radiation treatments can substantially reduce the time some people spend waiting for urgent treatment, improving the patient experience, a new study suggests. Patients who may benefit from this expedited process typically are experiencing pain or other debilitating symptoms, such as an airway blockage.

Researchers offer hypothesis for long COVID brain fog

AuntMinnie

A group in France has offered an explanation for long COVID brain fog, with the concept based on a visual brain pattern they discovered on patient PET scans, according to a study published October 13 in Medical Hypotheses. “We hypothesize that the hypometabolism pattern observed in long COVID patients with brain fog using F-18 FDG-PET might primarily be a signature of astrocyte-related glutamatergic dysregulation,” wrote lead study author Eric Guedj, MD, PhD, of Marseille University Hospital.

Background: Hemorrhage is the leading cause of trauma related mortality. The initial injury is often complicated by multifactorial coagulopathy that can exacerbate bleeding. Fibrinogen is the precursor to fibrin and a major component of stable clot formation. Fibrinogen and fibrin are often depleted during major trauma as a result of consumption, breakdown, and dilution.
