Deep Learning Using Preoperative AS-OCT Predicts Graft Detachment in DMEK.

Purpose: To evaluate a novel deep learning algorithm to distinguish between eyes that may or may not have a graft detachment based on pre-Descemet membrane endothelial keratoplasty (DMEK) anterior segment optical coherence tomography (AS-OCT) images.

Methods: Retrospective cohort study. A multiple-instance learning artificial intelligence (MIL-AI) model using a ResNet-101 backbone was designed.

Hearing outcomes in children with single sided deafness: Our experience at a tertiary paediatric otorhinolaryngology unit.

Introduction: Hearing rehabilitation options for single sided deafness (SSD) include contralateral routing of sound (CROS) aids and bone conduction devices (BCDs). This study aimed to review the management of children with SSD at our tertiary paediatric otolaryngology unit over the last 15 years.

Material And Methods: A retrospective cohort study was performed.

Simulation of "North Carolina Protocol for Allocating Scarce Inpatient Critical Care Resources in a Pandemic" in a Multi-hospital Health Care System.

An integrated nonprofit health care system with 13 North Carolina medical centers conducted a time-pressured quality improvement simulation of its plan to implement the "North Carolina Protocol for Allocating Scarce Inpatient Critical Care Resources in a Pandemic" attendant to pandemic scenario planning. Simulation objectives included assessing the plan in terms of a) efficiency and effectiveness; b) comorbidity scoring validity; c) impact by race/ethnicity, gender, age, and payer status; and d) simulation participant impressions of potential impact on clinicians. The simulation scenario involved scoring 14 patients with the constraint that only 10 could be afforded critical care resources.

Flexible transbronchial needle aspiration in the diagnosis of sarcoidosis.

The histopathologic diagnosis of sarcoidosis requires the presence of noncaseating granulomas. Transbronchoscopic lung biopsy (TBLB) has been considered the procedure of choice when less invasive tissue samples are unavailable. A total of 51 consecutive patients suspected of having sarcoidosis underwent combined TBLB and flexible transbronchial needle aspirate (TBNA).

Assessment of injury in transplanted and nontransplanted lungs after 6 h of cold storage with glutathione.

Single-lung transplantation after 3 h of hypothermic storage produces bilateral lung injury [pulmonary reimplantation response (PRR)]. We hypothesized that glutathione (GSH) hypothermic storage would protect both lungs from PRR for extended preservation times and that differences in injury and protection would be realized between the graft and the nontransplanted lung. Mongrel dogs underwent left single-lung autotransplantation after preservation for 5-6 h in Euro-Collins (EC) solution, EC plus exogenous GSH (EC+GSH), or Viaspan (VIA) at 4 degrees C.
