Multicenter Study Comparative StudyComparison between gallium-68 citrate positron emission tomography-computed tomography and gallium-67 citrate scintigraphy for infection imaging.
Preliminary studies have reported promising results for the utility of gallium-68 (Ga-68) citrate positron emission tomography-computed tomography (PET-CT) for infection imaging. This technique offers reduced radiation dose to patients, shorter time between injection and imaging and reduced time for image acquisition compared to the 'gold standard' nuclear imaging technique: gallium-67 (Ga-67) citrate scintigraphy. ⋯ The sensitivity and specificity of Ga-68 citrate PET-CT were found to be consistently lower than Ga-67 citrate scintigraphy. Additionally, due to the insufficient level of confidence of the reporting physicians for the Ga-68 citrate PET-CT, this modality could not currently be recommended to replace Ga-67 citrate scintigraphy for routine clinical use.

Multicenter Study Observational StudyPredictors of acute hospital mortality and length of stay in patients with new-onset atrial fibrillation: a first-hand experience from a medical emergency team response provider.
Atrial fibrillation (AF) occurs frequently following cardiothoracic surgery and treatment decisions are informed by evidence-based clinical guidelines. Outside this setting there are few data to guide clinical management. ⋯ Left ventricular systolic dysfunction in hospitalised patients with new-onset AF is associated with increased all-cause mortality whereas lower serum potassium levels are associated with an increased LOS. A prospective study is planned to compare outcomes based on in-hospital treatment strategies.

Case ReportsTroponin release after exertional vasovagal syncope.
Troponin release following exertional vasovagal syncope has not previously been reported. A young man was investigated after being admitted twice with exertional syncope, each time followed by a 10-fold spike in troponin I over 24 h. ⋯ During recovery, despite lying supine, he remained hypotensive for 5 min, with profound bradycardia and ST segment depression. We suspected that intense cardiovagal neural activity may have caused the troponin leak.
