CONCLUSION: Elective MMAE can be safely performed as an outpatient procedure without increased risk of postprocedural adverse events in most eligible patients with cSDH.

CONCLUSIONS: FESS significantly improves pain and function in both geriatric and nongeriatric adults with degenerative lumbar conditions, with no difference in the degree of improvement between groups.

Identifying population-level relationships between predators and their prey is often predicated on having reliable population estimates. Camera-trapping is effective for surveying terrestrial wildlife, but many species lack individually unique natural markings that are required for most abundance and density estimation methods. Analytical approaches have been developed for producing population estimates from camera-trap surveys of unmarked wildlife; however, most unmarked approaches have strict...

Background: Quantitative pupillometry has been proposed as an objective means to diagnose acute sports-related concussion (SRC). Objective: To assess the diagnostic accuracy of a smartphone-based quantitative pupillometer in the acute diagnosis of SRC. Methods: Division I college football players had baseline pupillometry including pupillary light reflex (PLR) parameters of maximum resting diameter, minimum diameter after light stimulus, percent change in pupil diameter, latency of pupil...

Restorative treatment is the most common approach to treating dental caries. However, after cavity preparation, some microorganisms may still persist in the substrate, suggesting the use of cavity disinfectants. Nevertheless, their effect on adhesion to composite resins is not yet fully understood, especially in primary teeth. The study aimed to assess the impact of five different cavity disinfectants on dentin adhesion in primary teeth. A total of 60 primary molars were uniformly flattened at...

Arachnoid granulations have been known for centuries yet remain incompletely understood. While traditionally associated with cerebrospinal fluid transport, the precise mechanism remains uncertain. This manuscript reviews the literature on the anatomy, histology, and imaging findings of arachnoid granulations and their mimickers and anomalous variations. We highlight variations in incidence, size, and characteristics of arachnoid granulations on imaging, and hypothesize that these variations may...

CONCLUSIONS: Smartphone-based quantitative pupillometry could be useful in differentiating between acute ischemic and hemorrhagic stroke.

Recent studies have revealed a role for zinc in insulin secretion and glucose homeostasis. Randomized placebo-controlled zinc supplementation trials have demonstrated improved glycemic traits in patients with type II diabetes (T2D). Moreover, rare loss-of-function variants in the zinc efflux transporter SLC30A8 reduce T2D risk. Despite this accumulated evidence, a mechanistic understanding of how zinc influences systemic glucose homeostasis and consequently T2D risk remains unclear. To further...

CONCLUSIONS: This contemporary multicenter observational cohort study demonstrated that machine learning modeling strategies did not improve performance of the ETVSS model over logistic regression.

CONCLUSIONS AND RELEVANCE: Although an abnormal NPi could indicate brainstem dysfunction, in this large and heterogeneous population of patients, NPi values were not significantly associated overall with ICP values. Repeated NPi measurements may not be a sufficient replacement for invasive monitoring.

BACKGROUND: Treatment of pediatric craniopharyngioma requires a multidisciplinary approach to counsel patients and families on the spectrum of treatment options, including biopsy, radiation, and/or resection. Gross-total resection can avoid radiation and its long-term comorbidities. In very young patients, this is of particular importance but is especially challenging because of anatomical considerations.

Vaccines targeting the complex pre-erythrocytic stage of Plasmodium parasites may benefit from the inclusion of multiple antigens. However, discerning protective effects can be difficult because newer candidates may not be as protective as leading antigens like the circumsporozoite protein (CSP) in the conventional pre-clinical mouse model. We developed a modified mouse model challenge strategy that maximizes the contribution of T cells induced by novel candidate antigens at the sporozoite...

CONCLUSION: MS and SRS are viable treatments for SM Grade III BAVMs. Treatment choice should be individualized by a multidisciplinary team, considering patient goals.

CONCLUSION: This study is the first to compare 30-day hospital readmissions between FESS and nonendoscopic surgeries in a large, matched multicenter cohort. FESS significantly reduces both the length of postoperative hospital stay and 30-day readmission rates compared to nonendoscopic approaches, underscoring the safety and effectiveness of outpatient FESS. Future studies are needed to define the role of FESS in more complex spine procedures.

The results of a Phase 1 trial of autologous mitochondrial transplantation for the treatment of acute ischemic stroke during mechanical thrombectomy are presented. Standardized methods were used to isolate viable autologous mitochondria in the acute clinical setting, allowing for timely transplantation within the ischemic window. No significant adverse events were observed with the endovascular approach during reperfusion therapy. Safety outcomes in study participants were comparable to those of...

CONCLUSIONS: Using a modified Delphi consensus technique, best practice guidelines were developed focusing on the optimal standards for delivering NT to patients with localized PDAC. Given the prognostic importance of completing multimodality therapy, efforts to standardize and optimize the delivery of NT represent an immediate opportunity to decrease care variation and improve outcomes for patients with PDAC. Future research should focus on validating and implementing best practice standards...

GPR6 is an orphan G protein-coupled receptor with high constitutive activity found in D2-type dopamine receptor-expressing medium spiny neurons of the striatopallidal pathway, which is aberrantly hyperactivated in Parkinson's disease. Here, we solved crystal structures of GPR6 without the addition of a ligand (a pseudo-apo state) and in complex with two inverse agonists, including CVN424, which improved motor symptoms in patients with Parkinson's disease in clinical trials. In addition, we...

CONCLUSION: In a large cohort of patients with unruptured IAs who underwent 4D-CTA and VW-MRI, both irregular pulsation and WEI were independently associated with symptoms. Such measures could identify IAs at higher risk of growth or rupture.
