Randomized Controlled Trial
Outcome differences between PARAMEDIC2 and the German Resuscitation Registry: a secondary analysis of a randomized controlled trial compared with registry data.
There has been much discussion of the results of the PARAMEDIC2 trial, as resuscitation outcome rates are considerably lower in this trial than in country-level registries on out-of-hospital cardiac arrest (OHCA). Here, we developed a statistical framework to investigate this gap and to examine possible sources for observed discrepancies in outcome rates. ⋯ Our framework helps in the medical interpretation of the PARAMEDIC2 trial and the transferability of the trial's results for other EMS systems. Significantly higher rates of survival and favourable neurological outcome than reported in this trial could be possible in other EMS and health care systems.

Randomized Controlled Trial
Point-of-care ultrasonography-assisted nasogastric tube placement in the emergency department: a randomized controlled trial.
The complications of a blind procedure for gastric tube placement are well documented. POCUS has been widely used to confirm the position of blindly inserted gastric tubes, and it does not prevent complications caused by the blind method. We performed a randomized controlled trial to compare gastric tube insertion with real-time oesophagus visualization using POCUS to the standard technique. ⋯ POCUS enables real-time insertion of a gastric tube with high sensitivity, in a short time with high first-attempt success rate and limited passage-related complications. POCUS should be utilized for NGT insertion whenever expertise is available on the bedside.

The prognosis of myocardial infarction in patients with rapid atrial fibrillation (RAF) is poorly known. We sought to ascertain if troponin concentrations are associated with a higher risk of major adverse cardiovascular events (MACE) in patients with RAF and chest discomfort suggestive of coronary origin. ⋯ In patients with RAF who complain of chest pain, increased troponin levels are related to adverse cardiovascular outcomes.
