Article Synopsis
  • The Portuguese clinical guidelines recommend 24 hours of hospital monitoring for patients with traumatic brain injuries, even when initial CT scans are normal, despite evidence suggesting this may be unnecessary and potentially harmful.
  • A study analyzed the costs and outcomes of this practice, comparing data from 440 patients admitted in 2022, where only 0.5% developed new intracranial lesions during a 24-hour observation period and one patient (0.2%) died from unrelated causes.
  • The current monitoring protocol cost €163,157, significantly more than the hypothetical scenario of discharging patients after an initial normal CT scan, which would have cost €29,480, highlighting a difference of €133,677.

P2X7 is a purinergic receptor physiologically activated by extracellular ATP. Its activation induces proinflammatory responses, including cytokine release, reactive oxygen species formation, and cell death. Previous in vivo experimental models demonstrated that P2X7 blockade has anti-inflammatory effects; however, there are no drugs used in clinical therapy that act on the P2X7 receptor.

A systematic assessment is crucial to confirm the diagnosis of pulmonary hypertension (PH) and classify it based on its etiological mechanism. This case report describes a young woman with a recent diagnosis of Graves' disease who presented with exertional dyspnea and fatigue. The initial ultrasound heart examination indicated moderate tricuspid regurgitation, an increased estimated systolic pulmonary artery pressure (sPAP), and suggestive alterations of atrial septal communication.

Objective: Evidence on timing for mobilization after chronic subdural hematoma (cSDH) surgery is heterogeneous, and practices differ considerably among neurosurgical centers. The Impact of an Early Out-of-Bed Paradigm in Postoperative Outcomes of Chronic Subdural Hematomas: GET-UP Randomized Prospective Trial (GET-UP Trial) is a randomized clinical trial comparing a postoperative early mobilization protocol to bed rest. Previously reported results at clinical discharge and 1 month after surgery indicated a decreased risk of medical complications in the early mobilization group.
