Potassium Supplementation and Prevention of Atrial Fibrillation After Cardiac Surgery: The TIGHT K Randomized Clinical Trial.

Importance: Supplementing potassium in an effort to maintain high-normal serum concentrations is a widespread strategy used to prevent atrial fibrillation after cardiac surgery (AFACS), but is not evidence-based, carries risks, and is costly.

Objective: To determine whether a lower serum potassium concentration trigger for supplementation is noninferior to a high-normal trigger.

Design, Setting, And Participants: This open-label, noninferiority, randomized clinical trial was conducted at 23 cardiac surgical centers in the United Kingdom and Germany.

Transcranial Doppler Screening in a Regional Care Network for Sickle Cell Disease in the United Kingdom.

The risk of stroke in children screened with transcranial Doppler ultrasound in the United Kingdom is not known. We evaluated a clinician-led program using a risk assessment modified from the STOP protocol. High-risk classification included abnormal velocities in the anterior cerebral artery, and single abnormal scan if initial velocity >220 cm/s (high abnormal) or if preceded by at least 2 conditional scans.

Lemierre's syndrome presenting with peritonsillar abscess and VIth cranial nerve palsy.

Lemierre's syndrome is characterized by acute oropharyngeal infection complicated by internal jugular venous thrombosis secondary to septic thrombophlebitis, and metastatic abscesses. We report a case of Lemierre's syndrome in an 18-year-old Caucasian woman presenting with a peritonsillar abscess and ipsilateral VIth cranial nerve palsy.
