In patients who remain comatose after cardiac arrest, quantitative DWI MRI findings correlate with early recovery of consciousness. A DWI MRI threshold of 650 × 10(-6) mm(2)/s in ≥10% of brain volume can differentiate patients with good versus poor outcome, though in this patient population the threshold was not 100% specific for poor outcome.

Recent evidence suggests that specialized proresolving lipid mediators (SPMs) generated from docosahexaenoic acid (DHA) can modulate the vascular injury response. However, cellular sources for these autacoids within the vessel wall remain unclear. Here, we investigated whether isolated vascular cells and tissues can produce SPMs and assessed expression and subcellular localization of the key SPM biosynthetic enzyme 5-lipoxygenase (LOX) in vascular cells. Intact human arteries incubated with DHA produced 17-hydroxy DHA (17-HDHA) and D-series resolvins, as assessed by liquid chromatography-tandem mass spectrometry. Addition of 17-HDHA to human arteries similarly increased resolvin production. Primary cultures of human saphenous vein endothelial cells (ECs) and vascular smooth muscle cells (VSMCs) converted 17-HDHA to SPMs, including resolvin D1 (RvD1) and other D-series resolvins and protectins. This was accompanied by a rapid translocation of 5-LOX from nucleus to cytoplasm in both ECs and VSMCs, potentially facilitating SPM biosynthesis. Conditioned medium from cells exposed to 17-HDHA inhibited monocyte adhesion to TNF-α-stimulated EC monolayers. These downstream effects were partially reversed by antibodies against the RvD1 receptors ALX/FPR2 and GPR32. These results suggest that autocrine and/or paracrine signaling locally generated SPMs in the vasculature may represent a novel homeostatic mechanism of relevance to vascular health and disease.-Chatterjee, A., Komshian, S., Sansbury, B.

Short- and long-term readmission rates in a safety net setting are high. The 30-day rates in this study are higher than historically reported. This data sets baseline rates for 90-day and 1-year readmission for future analyses. Although the majority of short-term readmissions are related to the index procedure, long-term readmission rates are more frequently related to systemic comorbidities. Targeted patient interventions aimed at preventing the most common reasons for readmission may improve readmission rates, particularly among patients with nonprivate insurance. However, other risk factors, such as tibial target, may not be modifiable and a higher readmission rate may need to be accepted in this population.

RPA access had lower technical success and primary patency compared with antegrade access at 6 months. There were no differences demonstrated between the two access techniques in perioperative morbidity and mortality or 6-month amputation, MALE, and survival. This technique should be considered when CFA access cannot be accomplished.

Background Historically, there has been uncertainty in the treatment of inferior turbinate hypertrophy (ITH) in children. Although management always begins with medical therapy, the decision to offer surgery in resistant cases is becoming more widely practiced. In the pediatric population, turbinate reduction can be achieved with turbinectomy, electrocautery, lasers, submucous microdebridement, and radiofrequency volumetric tissue reduction (RVTR). However, there remains a lack of consensus on the preferred approach to treatment. Objective To compare how the efficacy, duration, and complications of different surgical methods has changed the management of inferior turbinate hypertrophy in children over time. Methods In March 2018, a comprehensive literature search was performed in PubMed for all inferior turbinate hypertrophy management-related studies in children. Inclusion criteria included children (age, 1–17 years). Exclusion criteria included reviews and abstracts. Results Each technique has experienced a period of popularity over the last 30 years in parallel with the technology available at the time as well as evidence from studies in adults. The literature for ITH management in children has largely followed these trends, with a recent improvement in the quality of studies mirroring the overall increase in surgical practice. Of all methods currently used, RVTR and submucous microdebridement offer the least invasive and most efficacious relief of nasal obstruction. Conclusion This review provides an overview of the evolution of ITH management in children and, based on historic and current evidence, proposes the following graduated recommendation to treatment: (1) a 3-month trial of medical management, (2) evaluation for adenoid hypertrophy for consideration of concurrent adenoidectomy, and (3) RVTR or submucous microdebridement as the first-line surgical approach.

Infrainguinal arterial occlusive disease can lead to potentially disabling and limb-threatening conditions. Revascularization may be indicated for claudication, rest pain, or tissue loss. Although endovascular interventions are becoming more prevalent, open surgeries such as endarterectomy and bypass are still needed and performed regularly. Open reconstruction has been associated with postoperative morbidity, both at the local and at the systemic levels. Local complications include surgical site infections (SSIs 0–5.3%), graft failure (12–60%), and amputation (5.7–27%), and more systemic issues include cardiac (2.6–18.4%), respiratory (2.5%), renal (4%), neurovascular (1.5%), and thromboembolic (0.2–1%) complications. While such outcomes present an additional challenge to the postoperative management of surgical patients, it may be possible to minimize their occurrence through careful risk stratification and preoperative assessment. Therefore, individualized selection of candidates for open repair requires weighing the need for intervention against the likelihood of adverse outcomes based on preoperative risk factors. This review provides an overview of open reconstruction, focusing on identifying the clinical indications for surgery and perioperative morbidity and mortality.

Objectives/Hypothesis Electronic health records have brought many advantages but also placed a documentation burden on the provider during and after the clinic visit. Some otolaryngologists have countered this challenge by employing clinical scribes. This project aimed to better understand the influence of scribes on patient experience in the otolaryngology clinic. Study Design Retrospective cohort survey study. Methods Patients presenting to the otolaryngology clinic for new and follow‐up appointments were recruited to complete surveys about their experience. Results A total of 153 patients completed the survey, and 96 of those patients (62.7%) interacted with a scribe. Patient satisfaction was not significantly associated with participation of the scribe (P = .668). Similarly, patient rating of their physician on a scale of 1 to 10 was not associated with scribe involvement (P = .851). The patients who did interact with a scribe responded that the scribe positively impacted the visit 77.1% of the time. Participation of a resident, primary language other than English, and use of interpreter were associated with lower satisfaction (P = .004, P < .001, and P < .001, respectively). Conclusions There are no published data on the effect of scribes on patient experience in the otolaryngology clinic. In other specialties, scribes have been demonstrated as having a positive effect on provider satisfaction, clinical productivity, and patient perception. These data demonstrate that patient satisfaction was neither impaired nor improved by the presence of the scribe in this clinic. In light of benefits demonstrated by prior studies, these findings support the conclusion that scribes are a useful adjunct in providing high‐level otolaryngology care.

Among patients undergoing EVAR, ESRD is independently associated with higher perioperative and 1-year mortality despite not being associated with higher postoperative complications. This should be taken into account during informed consent for EVAR and risk-benefit considerations in this high-risk population, particularly for elective repair.
