Review Meta Analysis
Effects of sniffing position for tracheal intubation: a meta-analysis of randomized controlled trials.
The purpose of this meta-analysis was to validate the efficacy of the sniffing position in the performance of intubation with direct laryngoscopy. ⋯ Compared with the other head positions, the sniffing position did not improve glottic visualization, success rate of the first intubation, or intubation time. However, the sniffing position was significantly associated with better Intubation Difficulty Scale compared with the simple head extension position. (RR,1.28; 95% CI, 1.15-1.42; p<0.0001) CONCLUSIONS: Although patients do not benefit from the sniffing position in terms of glottic visualization, success rate of the first intubation, or intubation time, the sniffing position can still be recommended as the initial head position for tracheal intubation because the sniffing position provides easier intubation conditions.

Observational Study
Impact of device selection and clip duration on lung ultrasound assessment in patients with heart failure.
Pulmonary edema is a common sign of heart failure and can be quantified by counting vertical artifacts (B-lines) on lung ultrasound (LUS). The primary aim of this study was to compare a pocket size ultrasound device to high-end ultrasound systems on the measured number of B-lines. We also compared the impact of different-length ultrasound clips on the measured number of B-lines. ⋯ Our findings suggest significant differences based on LUS clip duration rather than the type of ultrasound device used, with respect to the number of B-lines detectable in patients with heart failure. These factors should be considered in the design and reporting of LUS studies and in longitudinal assessments of heart failure patients.

Multicenter Study Observational Study
Association between time to percutaneous coronary intervention and hospital mortality in non-ST-elevation myocardial infarction: a prospective multicenter observational study.
This study aimed to investigate the association between time to percutaneous coronary intervention (PCI) and hospital mortality in non-ST-elevation myocardial infarction (NSTEMI). ⋯ Percutaneous coronary intervention earlier than 6 hours after ED presentation was associated with higher hospital mortality than PCI 6 hours later in NSTEMI. However, the effect disappeared in the long S2D group.
