Twelve tips to aid interpretation of post-assessment psychometric reports.

Post-assessments psychometric reports are a vital component of the assessment cycle to ensure that assessments are reliable, valid and fair to make appropriate pass-fail decisions. Students' scores can be summarised by examination of frequency distributions, central tendency measures and dispersion measures. Item discrimination indicies to assess the quality of items, and distractors that differentiate between students achieving or not achieving the learning outcomes are key.

Stabilisation of coronary stents using rapid right ventricular pacing.

Aims: Excessive movement of coronary stents within the artery can make precise stent placement difficult. This study assessed the use of rapid right ventricular pacing to reduce stent motion to improve the accuracy of placement.

Methods And Results: During percutaneous coronary intervention, if excessive stent movement prevented accurate stent placement, rapid right ventricular pacing was performed to reduce stent motion within the coronary artery during both stent positioning and deployment.

Increased pulse wave velocity is not associated with elevated augmentation index in patients with diabetes.

Objective: Increased arterial stiffness is a risk factor for cardiovascular disease and is a feature associated with diabetes. Pulse wave velocity (PWV) is an accepted index of arterial stiffness and augmentation index (AI) derived from radial applanation tonometry has been advocated as a measurement of arterial stiffness. This study compares the relationship between PWV and AI in people with and without diabetes.

Jittery, a Mutator distant relative with a paradoxical mobile behavior: excision without reinsertion.

The unstable mutation bz-m039 arose in a maize (Zea mays) stock that originated from a plant infected with barley stripe mosaic virus. The instability of the mutation is caused by a 3.9-kb mobile element that has been named Jittery (Jit).
