Hoppo et al evaluate use of hypopharyngeal multichannel intraluminal impedance in patients with idiopathic chronic cough to determine whether laryngopharyngeal reflux or high-esophageal reflux was the cause of the cough. See the invited critique by Patti.
This article reviews the pathophysiology, clinical presentation, diagnostic evaluation, and treatment of gastroesophageal reflux disease.
Musallam et al evaluate the association between current and past smoking on the risk of postoperative mortality and vascular and respiratory events in patients undergoing major surgery.
This randomized clinical trial assesses the efficacy and safety of standard gastric bypass vs distal gastric bypass in patients with a BMI of 50 to 60.
This cohort study evaluates the effect of an endovascular-first protocol for patients with a ruptured abdominal aortic aneurysm on perioperative mortality and associated early clinical outcomes.
To determine the safety and effectiveness of endobronchial ultrasonography (EBUS)–guided transbronchial needle aspiration as a key component of a preoperative staging algorithm for lung cancer in veterans, Cornwell et al compared groups undergoing EBUS vs PET/CT only. The accuracy of nodal staging was compared with the final pathological staging after complete nodal dissection. See the Invited Commentary by Fisichella.
This study reports that rigorous risk-adjusted surgical quality assessment can be performed solely with objective variables. By leveraging data already routinely collected for patient care, this approach allows for wider adoption of quality assessment systems in health care.
To evaluate the early experience with transfemoral transcatheter aortic valve replacement (TAVR), Omer et al reviewed the records of all patients who underwent the procedure during the first year of their program. All patients received TAVR with the SAPIEN transcutaneous valve, and outcomes were assessed. See the Invited Commentary by Kelly and Mudy.
