High flow nasal cannula oxygen therapy for respiratory support in term infants

7 months 3 weeks ago
High flow nasal cannula oxygen therapy for respiratory support in term infants Review question Does high flow nasal cannula oxygen therapy improve the health outcomes of critically ill newborn infants requiring support for their breathing? Background When newborn infants have difficulty breathing, they may need external support to help move air in and out of their lungs (ventilation). There are various methods used to provide this breathing support. Invasive ventilation delivers air via a breathing tube placed in the baby's windpipe. Non-invasive ventilation delivers air via a mask that can...

What are the benefits and risks of covered stents compared with conventional bare stents for transjugular intrahepatic portosystemic shunt in people with liver cirrhosis?

7 months 3 weeks ago
What are the benefits and risks of covered stents compared with conventional bare stents for transjugular intrahepatic portosystemic shunt in people with liver cirrhosis? Key messages – Expanded polytetrafluoroethylene (ePTFE)-covered stents may be more likely to reduce mortality (deaths), upper gastrointestinal bleeding, recurrence of ascites (a condition where fluid collects in spaces within your abdomen), and shunt dysfunction compared with bare stents of the same diameter. – Beneficial effects of ePTFE-covered stents remain unclear when comparing with bare stents of different diameters....

In adults, does oxygen therapy during the non-breathing period before intubation prevent complications?

7 months 3 weeks ago
In adults, does oxygen therapy during the non-breathing period before intubation prevent complications? What is intubation? Intubation is a medical procedure that involves insertion of a tube into the breathing passage during the course of anaesthesia before surgery or in life-saving emergency situations such as road-side trauma or in times of critical illness. The breathing tube serves as a portal for assisted ventilation. Why might oxygen therapy help? During the time when a person stops breathing after going to sleep ready for an operation before an oral breathing tube is inserted low...

Vocabulary interventions for second language learners up to six years of age

7 months 3 weeks ago
Vocabulary interventions for second language learners up to six years of age Key messages – Studies included in this review suggest that vocabulary interventions for L2 learners may benefit children's L2 vocabulary learning but have little to no effect on their listening comprehension skills, though the evidence is very uncertain. Vocabulary interventions probably improve their storytelling skills. – There is a need for more high-quality research that follows L2 learners over a longer time to investigate longer-term effects. This should include learners outside the USA. Why is this review...

What is the evidence that 'microclots' cause the post-COVID-19 syndrome, and is removal using plasmapheresis justified?

8 months ago
What is the evidence that 'microclots' cause the post-COVID-19 syndrome, and is removal using plasmapheresis justified? Key messages 1. The term 'microclots' is not the correct term for the particles being investigated in people with post-COVID-19 syndrome, as they are not clots. The term 'amyloid fibrin(ogen) particles' is more appropriate. 2. The evidence shows that amyloid fibrin(ogen) particles are found in healthy people and those with other diseases, so they are not unique to post-COVID-19 condition. 3. Patients should not receive plasmapheresis for this indication outside...
