Despite the enormous success of mumps vaccination campaigns around the world, there has recently been a significant increase in mumps cases and outbreaks in vaccinated populations. As a result, tracking the molecular epidemiology of mumps outbreaks has increased in importance. Here we examine the challenges and limitations associated with traditional molecular genotyping tools and compare […]
In May 2018, a rapid assessment and risk stratification pathway was implemented in Unscheduled Care for patients with suspected acute coronary syndrome, using high-sensitivity (hs) Troponin T. Patients could be ruled out and discharged within one hour of presentation to the Emergency Department. The assay was validated and its safety and clinical effectiveness assured through […]
Selenium (Se) is an essential trace element in many biological processes. Se is measured in many sample matrices. The gold standard Se measurement method is inductively coupled plasma mass spectrometry (ICP-MS). Monitoring alternative isotopes, applying correction factors, and utilizing ICP with a triple quadrupole mass spectrometer are approaches to mitigate the interference of doubly-charged gadolinium.
As interest in vitamins A and E has increased in recent years, so too has the need for rapid and reliable methods by which these compounds can be assayed. The development of a supercritical fluid chromatography–tandem mass spectrometry (SFC-MS/MS)-based method with an automated extraction procedure provides faster analysis than other chromatographic-based methods and improved specificity.
The COVID-19 pandemic demonstrated that in such situations there are some simple questions that benefit from fast answers: Who has got the disease; Who has had the disease; and Who remains unexposed. The technique of laser-induced breakdown spectroscopy has the potential to help answer these questions and we caught up with Professor Berlo (McGill University, […]
Barrett’s esophagus has been established as a pre-cancerous condition that increases an individual’s risk of developing esophageal cancer, and so regular monitoring people with Barrett’s esophagus can help improve the survival rates of those who develop cancer. However, diagnosis is usually by endoscopy, which is invasive, unpleasant and resource-intensive. CLI caught up with Charlene Tang […]
The COVID-19 outbreak caused by severe acute respiratory syndrome virus 2 (SARS-CoV-2) that was declared a pandemic in March 2020 has resulted in a the development of diagnostic tests and vaccines at an unprecedented speed. The development of de novo therapeutics, though, takes considerably longer, which is where the repurposing of existing drugs is being […]
The COVID-19 pandemic has reinforced the critical importance of diagnosis and access to these services, both at the individual and at a population level. The pandemic has also impacted the delivery of diagnostics and care for other medical conditions, such as HIV/AIDS, but similarly, lessons learned with COVID-19 can also be applied to improve diagnostic […]
Despite rapid advances in the areas of genomics and digital image analysis, cancer diagnosis remains largely reliant on tissue/cellular morphological assessment by an expert pathologist. Here, we summarize a newly developed approach to histology, based on a plasmon-induced colour change which provides instant, label-free visualization (or contrast) of cancer cells, distinguishing them from other cells […]
