We show no improvement in pathogen detection or genome recovery X10 with longer turnaround time and higher failure rates for the dual-arm approach.

Heroic effort by Luke Snell, Suzy Pickering and Rui Galao and many colleagues at KCL, clinical collaborators at GSTT and of course the individuals concerned, several of whom sadly passed away.

This is finally out.

Very short take home. All the variation in spike that produced the immune escape characteristics of Omicron can occur in one single persistently infected individual over the period of a year.

This is why persistent infections matter

As #WorldAMRAwarenessWeek wraps up, we share how respiratory metagenomics is transforming care.

Faster and accurate detection of pathogens help clinicians target treatment sooner and reduce unnecessary antibiotics, whilst improving personalised care and antimicrobial stewardship across the NHS.

Use of paracetamol during pregnancy unchanged in the EU | European Medicines Agency (EMA) Paracetamol medicines can be used in pregnancy, in accordance with official recommendations

Paracetamol remains an important option to treat pain or fever in pregnant women.

Following rigorous assessment of the available scientific data, we find no evidence that taking paracetamol during pregnancy causes autism in children.
