Catheter-Related Right Atrial Endocarditis in a Dialysis Patient.

Hemodialysis catheters are frequently used for vascular access in end-stage chronic kidney disease patients lacking mature arteriovenous fistula. The incidence of infective endocarditis in hemodialysis patients is higher than in the general population and is associated with severe and potentially life-threatening complications. A high index of suspicion is imperative for early diagnosis and timely intervention to enhance the prognosis of this high-mortality condition.

An Unusual Case of Vasospastic Angina Resulting in Multiple Episodes of Cardiac Arrest.

Coronary vasospasm is a well-recognized cause of angina (also known as Prinzmetal angina) and a common cause of admissions to the emergency department and coronary intensive care units. It is however an uncommon cause of cardiac arrest. We describe a patient with multiple episodes of chest pain followed by cardiac arrest in pulseless electrical activity (PEA) due to coronary vasospasm.

Ultralarge suspended and perforated graphene membranes for cell culture applications.

With its high mechanical strength and its remarkable thermal and electrical properties, suspended graphene has long been expected to find revolutionary applications in optoelectronics or as a membrane in nano-devices. However, the lack of efficient transfer and patterning processes still limits its potential. In this work, we report an optimized anthracene-based transfer process to suspend few layers of graphene (1-, 2- and 4-layers) in the millimeter range (up to 3 mm) with high reproducibility.

Pleural Sarcoidosis and Occult Lymphatic Anthracosis: An Unusual Symptomatic Association.

Unlabelled: Sarcoidosis is a chronic multisystemic inflammatory disease of unknown aetiology. Virtually any organ or system can be involved, resulting in a wide range of clinical presentation. Pleural sarcoidosis is rare.

Effect of adding vildagliptin to insulin in haemodialysed patients with type 2 diabetes: The VILDDIAL study, a randomized, multicentre, prospective study.

Aim: To evaluate the effect of adding the dipeptidyl-peptidase-4 inhibitor vildagliptin to insulin on the glycaemic control of patients with type 2 diabetes undergoing haemodialysis.

Methods: Overall, 65 insulin-treated patients with type 2 diabetes undergoing haemodialysis (HbA1c: 7.3% ± 1.
