Imaging biotin trafficking in vivo with positron emission tomography.

J Med Chem 2020 Jul 13. Epub 2020 Jul 13.

The water-soluble vitamin biotin is essential for cellular growth, development and well-being but its absorption, distribution, metabolism, and excretion are poorly understood. This paper describes the radiolabelling of biotin with the positron emission tomography (PET) radionuclide carbon-11 ([C]biotin) to enable the quantitative study of biotin trafficking in vivo. We show that intravenously administered [C]biotin is quickly distributed to liver, kidneys, retina, heart and brain in rodents - consistent with the known expression of the biotin transporter - and a surprising accumulation in brown adipose tissue (BAT).

Routine determination of troponin levels is recommended for all patients with acute ischemic stroke. In 20-55% of these patients the troponin levels are elevated, which may be caused by ischemic as well as non-ischemic myocardial damage and particularly neurocardiogenic myocardial damage. In patients with acute ischemic stroke, the prevalence of previously unknown coronary heart disease is reported to be up to 27% and is prognostically relevant for these patients; however, relevant coronary stenoses are less frequently detected in stroke patients with troponin elevation compared to patients with non-ST elevation myocardial infarction.

Improved diagnosis of pulmonary embolism causing cardiac arrest by combined endobronchial ultrasound and echocardiography.

Cardiovasc Ultrasound 2020 Jul 6;18(1):25. Epub 2020 Jul 6.

Department of Anaesthesia and Critical Care, Cardiothoracic and Vascular Anaesthesia and Intensive Care Medicine, Azienda Ospedaliero Universitaria Pisana, Via Paradisa 2, 56124, Pisa, Italy.

Background: Pulmonary embolism (PE) is a life-threatening disease difficult to diagnose and manage in severe hemodynamic unstable patients. Transoesophageal echocardiography (TEE) is considered useful to improve diagnosis, but such approach has physical limitations for the interposition of the airways preventing the clear assessment of the left pulmonary artery. Endobronchial ultrasound (EBUS), a recently developed technique carried out using a modified bronchoscope having a small ultrasound convex probe at the tip allowing to perform ultrasonography examination of the mediastinum, can extensively visualize the pulmonary arteries on both sides.

Carotid intima-media thickness and subclinical left heart dysfunction in the general population.

Atherosclerosis 2020 Jun 15;305:42-49. Epub 2020 Jun 15.

Department of Cardiovascular Medicine, The University of Tokyo, Tokyo, Japan.

Background And Aims: Although carotid intima-media thickness (IMT) is an established marker of atherosclerosis and carries independent risk for cardiovascular disease, its possible association with subclinical cardiac dysfunction has not been extensively evaluated. Left ventricular global longitudinal strain (LVGLS) and peak left atrial longitudinal systolic strain (PALS) can detect subclinical left heart dysfunction. This study aimed to investigate the association between carotid IMT and subclinical left heart dysfunction in a sample of the general population without overt cardiac disease. Read More
