Preparation and response to COVID-19 outbreak in Singapore: A case report.

The COVID-19 pandemic has an overwhelming impact on the nursing profession. Nurses play a vital role before and during pandemics, with nurse leaders taking the lead in preparation for outbreaks. In response to an outbreak, early recognition and preparation for the increasing threat, managing staffing challenges together with the well-being of nurses are of utmost importance.

Cavitation-induced traumatic cerebral contusion and intracerebral hemorrhage in the rat brain by using an off-the-shelf clinical shockwave device.

Traumatic cerebral contusion and intracerebral hemorrhages (ICH) commonly result from traumatic brain injury and are associated with high morbidity and mortality rates. Current animal models require craniotomy and provide less control over injury severity. This study proposes a highly reproducible and controllable traumatic contusion and ICH model using non-invasive extracorporeal shockwaves (ESWs).

Focused shockwave induced blood-brain barrier opening and transfection.

Despite extensive efforts in recent years, the blood-brain barrier (BBB) remains a significant obstacle for drug delivery. This study proposes using a clinical extracorporeal shockwave instrument to open the BBB, combined with a laser assisted bi-axial locating platform to achieve non-invasive, controllable-focus and reversible BBB opening in the brains of rats. Under shockwave treatment with an intensity level of 5 (P9.
