Surgery versus surveillance for ascending aortic aneurysms in elderly patients.

Background: Whether elderly patients with aortic root or ascending aortic aneurysm (ATAA) would benefit from the new surgical size threshold of 5.0 cm is unknown. This study aimed to evaluate the natural history of ATAA in elderly patients and to compare long-term outcomes of those who underwent initial surveillance versus surgery.

The contributions of motor skill proficiency to cognitive and social development in early childhood.

With limited evidence from intervention studies, causal relationships between motor competence and cognitive and social development have yet to be clearly established. In this research, we investigated whether a targeted training programme to improve fundamental movement skills (i.e.

Safe(r) Landing by Older People: A Matter of Complexity.

Maintaining balance is a complex motor problem that requires coordinated contributions from multiple biological systems. Aging inevitably lessens the fidelity of biological systems, which can result in an increased risk of falling and associated injuries. It is advantageous to land safely, but falls manifest in diverse ways, so different motor solutions are required to land safely.

Exploring the Correlation of Dynamic Surface Tension with Antimicrobial Activities of Quaternary Ammonium-Based Disinfectants.

Quaternary ammonium compound (QAC) disinfectants represent one of our first lines of defense against pathogens. Their inhibitory and bactericidal activities are usually tested through minimum inhibitory concentration (MIC) and time-kill assays, but these assays can become cumbersome when screening many compounds. We investigated how the dynamic surface tension (DST) measurements of QACs correlate with these antimicrobial activities by testing a panel of potent and structurally varied QACs against the gram-positive Staphylococcus aureus and the gram-negative Pseudomonas aeruginosa.
