Objective: In chronic obstructive pulmonary disease (COPD) patients with acute respiratory failure (ARF), bronchodilating agents administered by inhalation have, in general, little effect on dynamic hyperinflation and concurrent static intrinsic positive end-expiratory pressure (PEEPi,st). Since in COPD the severely obstructed segments of the lung may not be reached by inhaled medication, we reasoned that drug efficiency may be enhanced by intravenous administration of the agent.
Design: Physiological study.
Setting: Two four-bed surgical-medical ICUs of a university hospital.
Patients: Fourteen COPD patients were studied within 36 h from the onset of ARF.
Measurements And Results: Static compliance (Cst,rs), minimal (Rmin,rs) and additional (DeltaRrs) resistance of the respiratory system, and PEEPi,st were measured before and after intravenous administration of salbutamol. All patients had limitation of air flow before and after salbutamol administration. On average, after salbutamol there was a small, though significant, decrease in Rmin,rs (-9%), DeltaRrs (-12%) and PEEPi,st (-8%).
Conclusion: The changes in resistance and PEEPi,st after intravenous administration of salbutamol were too small to be of clinical significance.

Atherosclerosis (AS) is a prevalent inflammatory vascular disease characterized by plaque formation, primarily composed of foam cells laden with lipids. Despite lipid-lowering therapies, effective plaque clearance remains challenging due to the overexpression of the CD47 molecule on apoptotic foam cells, inhibiting macrophage-mediated cellular efferocytosis and plaque resolution. Moreover, AS lesions are often associated with severe inflammation and oxidative stress, exacerbating disease progression.

Cardiac computed tomography angiography (CTA) is a valuable tool in the assessment of congenital and acquired cardiac disease in children. The goal of cardiac CTA is to produce images that are free of motion and provide sufficient characterization of the anatomy in question. Given the complexity of pediatric patient characteristics, including patient size, heart rate, breath-holding capability, and variant anatomy, cardiac CTA technique must be individualized to the patient as well as the indication to answer the clinical question while also minimizing radiation exposure.

Background And Objective: Psilocybin is currently being extensively studied as a potential therapeutic agent for multiple psychiatric disorders. Here, a systematic literature review of all published pharmacokinetic data on the pharmacologically active metabolite of psilocybin, psilocin, is presented.
Methods: The review includes clinical studies that reported pharmacokinetic data and/or parameters after psilocybin administration in humans.
Introduction: Pain control following Nuss thoracoplasty remains a challenge. Cryoanalgesia of the intercostal nerves has been demonstrated to reduce postoperative pain in these patients. The objective of this study was to understand how and how widely cryoanalgesia is used in pediatric patients undergoing funnel chest surgery in Spain.

Rationale: Postpartum haemorrhage (PPH) is common and potentially life-threatening. The antifibrinolytic drug tranexamic acid (TXA) is thought to be effective for treating PPH. There is growing interest in whether TXA is effective for preventing PPH after vaginal birth.
