We need a people’s vaccine

As vaccine nationalism and inequitable distribution continue to plague the global rollout of COVID-19 vaccines, epidemiologists from leading academic institutes around world have issued a stark warning that so-called ‘variants of concern’ to SARS-CoV-2, the virus that causes COVID-19, could render current vaccines ineffective in less than a year. Callan Emery reports.


Reducing costs, improving outcomes with AI in a radiology practice

A study published in the Journal of Digital Imaging (2019) [1] looked at whether Artificial Intelligence (AI)-based, computer-aided detection (CAD) software can be used to reduce false positives per image (FPPI) on mammograms as compared to an FDA-approved conventional CAD. The study showed a 69% decrease in FPPI which, the researchers said, could also potentially […]


Superbugs and failing drugs

Bacteria that develop resistance to antibiotic drugs – superbugs – pose a major global health threat to humanity. In a concerted effort to stave off this threat, several global programmes have been established and numerous new research initiatives are being carried out. Whether they are successful is yet to be seen. International Hospital reports. Antimicrobial […]



As the threat of a COVID-19 pandemic stares us in the face, it may be opportune to consider some scenarios ahead, especially in light of lessons from other, similar outbreaks in recent decades. The first problem is sporadic bursts of public concern, alternating with periods of denial. Managing both requires measured doses of reliable information […]


The challenge of sepsis: new approaches to old scourge

Sepsis is a potentially fatal condition after the immune system over-reacts to an infection, leading to shock and organ failure. It is most frequently provoked by commonplace bacteria. Globally, over 30 million people develop sepsis each year. Some 6 million die as a result. Although there has been progress in controlling deaths from sepsis in […]


How artificial intelligence will change the role of doctors

The term “artificial intelligence”, defined in the Oxford Dictionary as “the capacity of a machine to simulate or surpass intelligent human behaviour”, was first used in the 1950s, but the idea that the human brain, or at least parts of it, could somehow be ‘copied’ or ‘imitated’ using a series of mechanical networks has been […]
