It can be helpful to assess blood oxygen levels in patients when they are walking if that level is normal when they are sitting, a new study suggests. A low level of oxygen in the blood, or hypoxia, contributes to shortness of breath and worsening illness in patients with COVID-19. At 10 Chicago-area hospitals, doctors studied 531 COVID-19 patients whose blood oxygen levels were normal at rest. Roughly one in four developed hypoxia when they got up and walked. These individuals were nearly five times more likely to eventually need bas

Pregnant women are among those most in need of safe and effective therapies against COVID-19, but they are routinely excluded from the majority of clinical treatment trials, according to authors of an opinion piece based on a review of international trial registry data, published in
The Lancet Global Health journal.
Strikingly, three-quarters of COVID-19 trials reviewed specifically excluded expectant mothers, even though they were investigating medications and vitamins that already have a relatively favourable safety profile during pregnancy, or that are already used in pregnant women.
In the Viewpoint, authors raise concerns that the ongoing exclusion of pregnant women will result in lost opportunities to ensure the effectiveness and safety of treatments in expectant mothers who may be at increased risk of severe outcomes from COVID-19 illness. They argue that given the scale of the pandemic and those that will inevitably follow, there is a public health obligation

Pregnant women should be given the right to make their own informed decision to participate in clinical studies on Covid-19 treatments, experts have said.
In an opinion piece published in the journal The Lancet Global Health, the scientists have said that mothers-to-be have been excluded from more than three quarters of Covid-19 treatment trials.
The authors warned that the “exclusion poses risk to potential treatment effectiveness and safety for pregnant women who may be at increased risk of severe Covid-19 illness”.
They argued that there is “a public health obligation to include pregnant women in treatment trials to identify and provide appropriate management and care”.
