Radiotherapy: ‘What Is Theranostics?’ (Video)

What is Theranostics? Dr. Martin Pomper, Director of the Nuclear Medicine and Molecular Imaging division at Johns Hopkins, describes the mechanisms of a groundbreaking cancer treatment that combines imaging and molecular radiotherapy. With this method, radiopharmaceuticals can specifically target cancer cells while sparing most normal tissues.

COVID-19: ‘WHY VARIANTS ARE SPREADING FASTER’

As highly transmissible coronavirus variants sweep across the world, scientists are racing to understand why these new versions of the virus are spreading faster, and what this could mean for vaccine efforts. New research says the key may be the spike protein, which gives the coronavirus its unmistakable shape. Illustration: Nick Collingwood/WSJ

ANALYSIS: MULTIRESISTANT BACTERIA THAT OUTSMART ANTIBIOTICS (VIDEO)

Antimicrobial resistance is one of the greatest medical challenges of our time. Among the causes are industrial livestock farming, poor hygiene in hospitals, and the misuse of antibiotics. This documentary looks at approaches to fighting multiresistant strains of bacteria.

Each year 33,000 people in Europe die after becoming infected with bacteria that are resistant to antibiotics. Hygiene specialist Dr. Ron Hendrix has been working for years to prevent outbreaks of infectious disease in hospitals. Dr. Hendrix says that he and other experts in the Netherlands recognized early on that they’d have to fight the spread of bacteria just as actively as they would the actual infection.

Hendrix has convinced a number of German hospitals to re-open their diagnostic laboratories, as well. In the early 2000s, many of these labs had been shut down as a cost-cutting measure. And farmers in Denmark voluntarily chose to sharply reduce their use of antibiotics, after evidence showed that intensive livestock farming caused multiresistant bacteria to multiply.

Infectious disease specialist Dr. Patrick Soentjens was able to convince Belgium’s health ministry to allow the use of “phages” to treat stubborn antimicrobial resistant pathogens. Phages are special viruses that kill bacteria. Dr. Soentjens is certain that this well-known, but largely forgotten option could save many lives. Belgium has become the first western European country where phages have been officially recognized as a legitimate medical treatment.
