Brachial artery blood flow by vascular ultrasound in education
Adv Physiol Educ. 2022 Jul 7. doi: 10.1152/advan.00157.2021. Online ahead of print.ABSTRACTThere is extensive and increasing use of ultrasound in medical care and scientific research, so it is important that the technique, indication, and interpretation of ultrasound investigations are included in medical and biological education. Applications of ultrasound in medical care and education employ not only non-invasive imaging of structure but also the evaluation of organ function. Vascular ultrasound is one such application which has been hitherto relatively neglected in physiology education. The techniques of vascular ultras...

Hemodynamic influences on mesenteric blood flow in shock conditions
Am J Med Sci. 2021 May 4:S0002-9629(21)00154-3. doi: 10.1016/j.amjms.2021.04.014. Online ahead of print.ABSTRACTThe gastrointestinal (GI) tract, especially the mucosa, is the most vulnerable organ to hypoperfusion among the splanchnic organs. Disturbed perfusion of the mesenteric area may lead to GI dysfunction, cause further injury to the patients and even vital outcomes. However, due to the limitation of detection methods, the hemodynamic influences on mesenteric blood flow in clinical practice are not fully understood. By elucidating the underlying mechanisms, we may be able to recognize disturbed GI perfusion and event...

TACTICS - Trial of Advanced CT Imaging and Combined Education Support for Drip and Ship: evaluating the effectiveness of an 'implementation intervention' in providing better patient access to reperfusion therapies: protocol for a non-randomised controlled stepped wedge cluster trial in acute stroke
BMJ Open. 2022 Feb 11;12(2):e055461. doi: 10.1136/bmjopen-2021-055461.ABSTRACTINTRODUCTION: Stroke reperfusion therapies, comprising intravenous thrombolysis (IVT) and/or endovascular thrombectomy (EVT), are best practice treatments for eligible acute ischemic stroke patients. In Australia, EVT is provided at few, mainly metropolitan, comprehensive stroke centres (CSC). There are significant challenges for Australia's rural and remote populations in accessing EVT, but improved access can be facilitated by a 'drip and ship' approach. TACTICS (Trial of Advanced CT Imaging and Combined Education Support for Drip and Ship) aim...

Investigation of medical intervention with fatal outcome: the impact of post-mortem CT and CT angiography
Abstract Post-mortem computed tomography (PMCT) has been proven for its appropriateness to become an integral part of routine pre-autoptic forensic investigations either in the field of forensic investigation of fatal medical error or in hospital quality management. The autoptic investigation of unexpected and peri-interventional deaths can be usefully guided by post-mortem imaging which offers significant added value in the documentation of misplacement of medical devices before dissection with the risk of artificial relocation and the detection of iatrogenic air embolism. Post-mortem CT angiography (PMCTA) augme...

Minimally invasive esophagectomy
ConclusionsMinimally invasive surgery for esophageal malignancies offers advantages when performed in an environment with sufficient expertise and caseload. Whether robotic-assisted minimally invasive esophagectomy further improves the results has to be investigated in the future. Intraoperative nerve monitoring and visualization of the graft perfusion with indocyanine green fluorescein should be used where available. Enhanced recovery protocols after surgery have become standard.

What are Some of the Complications of Short Bowel Syndrome?
Discussion Necrotizing enterocolitis (NEC) is one of the most common gastrointestinal emergencies in neonates. Mortality rates are from 0-45% depending on infant weight and gestation with more premature and smaller infants having greater mortality. NEC usually occurs in premature infants but it also occurs in term infants. The etiology is unknown but is probably multifactorial with ischemia and/or reperfusion playing some role. There are ‘outbreaks’ of NEC but no causative organism has been identified. Regardless of the originating cause, inflammation of the intestine and release of inflammatory mediators causes variou...
