Review Meta Analysis
Cervical spine injuries in adults ≥ 65 years after low-level falls - A systematic review and meta-analysis.
Adults ≥ 65 are at risk of cervical spine (C-spine) injury, even after low-level falls. The objectives of this systematic review were to determine the prevalence of C-spine injury in this population and explore the association of unreliable clinical exam with C-spine injury. ⋯ Adults ≥ 65 years are at risk of cervical spine injury after low-level falls. More research is needed to determine whether there is an association between cervical spine injury and GCS < 15 or altered level of consciousness.

Appendicitis is one of the most common surgical emergencies globally and it can both be difficult to diagnose but also to differentiate complicated from uncomplicated appendicitis preoperatively. The objective of this scoping review was to develop an overview of biomarkers in blood discriminating complicated from uncomplicated appendicitis and characterize their applicability in an acute setting including time, cost, and analysis technique required as well as their individual precision. ⋯ Routine biomarkers were applicable in an acute setting but had poor diagnostic accuracy. Novel biomarkers are being investigated for potential, but the concept is still premature due to lack of diagnostic accuracy studies reporting cost-benefit for individual markers and whether they can be applied in an acute setting.

Computed tomography (CT) is performed in over 90% of patients diagnosed with ureteral stones, but only 10% of patients presenting to the emergency department (ED) with acute flank pain are hospitalized for a clinically important stone or non-stone diagnosis. Hydronephrosis can be accurately detected using point-of-care ultrasound and is a key predictor of ureteral stone and risk of subsequent complications. The absence of hydronephrosis is insufficient to exclude a stone. We created a sensitive clinical decision rule to predict clinically important ureteral stones. We hypothesized that this rule could identify patients at low risk for this outcome. ⋯ Application of this clinical decision rule to imaging decisions would have led to 63% fewer CT scans with a miss rate of 0.4%. A limitation was the application of our decision rule only to patients who underwent CT for suspected ureteral stone. Thus, this rule would not apply to patients who were thought to have ureteral colic but did not receive a CT because ultrasound or history were sufficient for diagnosis. These results could inform future prospective validation studies.

Compare heart rate control between parenteral metoprolol and diltiazem and identify safety outcomes in the acute management of atrial fibrillation (AFib) with rapid ventricular response (RVR) in patients with heart failure with reduced ejection fraction (HFrEF). ⋯ Our study provides further evidence that short term use of diltiazem is likely as safe and effective as metoprolol in the acute management of HFrEF patients with AFib RVR and provides support for the use of non-dihydropyridine calcium channel blockers (non-DHP CCBs) in this patient population.

Case Reports
Bottle it up: Prehospital management of an AV fistula bleed using a bottle cap: A case report.
Hemorrhage from arteriovenous fistula sites is a known complication with potentially fatal consequences. The management of AV fistula hemorrhage has historically included direct pressure, tourniquet use, and/or surgical management. We describe a case of a 71-year-old female with hemorrhage from an AV fistula site that was successfully managed in the prehospital setting using a simple bottle cap.
