Using a Model Created Using a 3D Printer to Mould a Grey Cast Iron Casting.

This article deals with the possibility of using 3D-printed models as an input for the production of a mould for cast iron castings. This new progressive process is significantly faster (with sufficient accuracy) compared to the current way of making models for moulds. The need to create a wooden model is removed by this process.

Decrease in longitudinal strain in heart transplant recipients is associated with rejection.

Background: Around 20-40% of heart transplant patients experience moderate to severe rejection within the first year after heart transplantation. Endomyocardial biopsy (EMB) is a gold standard for diagnosing heart transplant rejection. There is a need for non-invasive alternatives that allow for early, safe and reliable diagnosis of acute graft rejection prior to the onset of clinical symptoms.

Arterial stiffening contributes to impairment of cerebrovascular reactivity in patients with coronary artery disease without carotid stenosis.

Impaired cerebrovascular reactivity (CVR), an important risk factor for future stroke, is affected by a presence carotid stenosis. However, in some cases CVR can be impaired in the absence of carotid stenosis due to several poorly characterized mechanisms. We hypothesized that arterial stiffening as observed in coronary heart disease (CHD) could be associated with alteration in CVR in CHD patients without carotid stenosis.

Comparison of rocuronium and succinylcholine on postintubation sedative and analgesic dosing in the emergency department.

Objectives: Rocuronium and succinylcholine are both commonly used neuromuscular blockers for rapid sequence intubation in the emergency department (ED). The objective of this study was to determine if patients who receive rocuronium are more likely to receive lower doses of postintubation sedatives and analgesics compared with patients who receive succinylcholine.

Methods: This was a retrospective cohort study carried out in a tertiary, academic ED.
