Background: Currently, no evidence compares outcomes for techniques utilizing surgical specimen extractions bags versus unprotected extraction.
Methods: Evaluation of sleeve gastrectomies performed at two high-volume centers. Cases where an extraction bag was used (+EB) were compared to bag-less extraction (-EB). Outcomes included operative contamination, surgical site infections and extraction-site hernias.
Results: 674 patients were evaluated (417 in the +EB group and 257 in the -EB group). Preoperative characteristics were similar between groups. There was a trend toward shorter operative times with the -EB group (-EB = 100 min vs + EB = 106 min, p = 0.07). Gross spillage was documented as a contaminated case in 0.4% of -EB cases compared to 1.2% in +EB cases (p = 0.51). Two superficial infections were appreciated (1.2% = +EB vs 0.7% = -EB, p = 0.7) with one post-operative abscess in the -EB group (p = 0.61). One post-operative hernia was seen in each group (p = 0.62).
Discussion: Bag-less extraction is a safe, resource conscious method that may potentially decreased operative time.

Traumatic brain injury (TBI), resulting from external forces, is a leading cause of disability and death, often leading to cognitive deficits that affect attention, concentration, speech and language, learning and memory, reasoning, planning, and problem-solving. Given the diverse mechanisms underlying TBI symptoms, it is essential to characterize its neurophysiological and neuropsychological effects. To address this, we employed weighted coherence (WC) analysis in patients performing the Halstead-Reitan categorization task, alongside a control group of eight healthy individuals.

Cardiovascular disease comprises a group of disorders affecting or originating within tissues and organs of the cardiovascular system; most, if not all, will eventually result in cardiomyocyte dysfunction or death, negatively impacting cardiac function. Effective models of cardiac disease are thus important for understanding crucial aspects of disease progression, while recent advancements in stem cell biology have allowed for the use of stem cell populations to derive such models. These include three-dimensional (3D) models such as stem cell-based models of embryos (SCME) as well as organoids, many of which are frequently derived from embryoid bodies (EB).

Purpose: Dynamic eye-tracking paradigms are an engaging and increasingly used method to study social attention in autism. While prior research has focused primarily on younger populations, there is a need for developmentally appropriate tasks for older children.
Methods: This study introduces a novel eye-tracking task designed to assess school-aged children's attention to speakers involved in conversation.

Introduction: Fungal keratitis is a leading cause of corneal blindness, with current antifungal treatments having limited efficacy. One promising treatment modality is Rose Bengal (RB) photodynamic antimicrobial therapy (PDAT) that has shown mixed success against fungal keratitis. Therefore, there is a need to explore the antimicrobial efficacy of other green-light activated photosensitizers that have deep penetration in the cornea to combat the deep fungal infections, such as Erythrosin B (EB) and Eosin Y (EY).
