Low rates of aortic surveillance imaging and clinical follow-up in patients with acute aortic dissection.

Objectives: Patients that survive acute aortic dissection (AD) remain at high risk of morbidity/mortality from structural changes of the aorta. Aortic surveillance is challenging, especially within a tertiary referral center. Our aim was to identify follow-up imaging and appointment rates, and factors associated with incomplete surveillance in patients with acute AD.

Pressure Enabled Drug Delivery (PEDD) Significantly Increases Intraarterial Delivery of Embolic Microspheres to Liver Tumors in a Porcine Model.

This study aims to test the hypothesis that Pressure Enabled Drug Delivery (PEDD) with a TriNav device would increase delivery of Embospheres via hepatic artery infusion to liver tumors in an oncopig model when compared to a conventional endhole microcatheter. Embospheres (100-300um in size) were fluorescently labeled and infused into porcine liver tumors using conventional technique (n=8) or by PEDD (n=8). Liver tissue was harvested and we analyzed images with a custom Visiopharm Deep Learning algorithm (Visiopharm A/S) to quantitate signal intensity.

Methods: A single-center retrospective review identified patients undergoing adrenalectomy by urologists from 2009 to 2023. Data were gathered on demographics, tumor characteristics, surgeon volume, surgical outcomes including length of procedure, estimated blood loss, length of stay, and complications identified by the Clavien-Dindo complication classification system.

Glioblastoma Multiforme: Sensitivity to Antimicrobial Peptides LL-37 and PG-1, and Their Combination with Chemotherapy for Predicting the Overall Survival of Patients.

Glioblastomas (GBMs) are the most malignant and intractable of all cancers, with an unfavorable clinical prognosis for affected patients. The objective was to analyze the sensitivity of GBM cells to the antimicrobial peptides (AMPs) cathelicidin (LL-37) and protegrin-1 (PG-1), both alone and in combination with chemotherapy, to predict overall survival (OS) in the patients. The study was conducted on 27 GBM patients treated in the neurosurgical department of the Almazov Medical Research Centre (Saint Petersburg, Russia) from 2021 to 2024.

Insertional Achilles Tendinopathy Treated With Botulinum Toxin: A Case Report.

Chronic insertional Achilles tendinopathy (IAT) is a common cause of recalcitrant heel pain. Patients present with pain localized to the Achilles tendon insertion at the calcaneus and have tenderness to palpation in this area on physical exam. Conservative management often includes an exercise prescription focusing on eccentric loading with limited dorsiflexion.

Managing Pediatric Hip Pain Patients with Precision.

Pediatric hip pain can have orthopedic, infectious, inflammatory, neoplastic, or nonmusculoskeletal etiologies. Organizing the differential diagnosis by symptom chronicity and a determination of intraarticular versus extraarticular pain, as well as the age at pain onset, can be helpful to hone in on the cause. Clinicians should consider plain radiographs in cases of acute trauma, with concern for bony pathology, or in patients with unexplained limp or hip pain, with musculoskeletal ultrasound and magnetic resonance imaging used as advanced imaging when indicated.

Leveraging Natural Product-Inspired Antifungals to Investigate the Mechanism of Action of Peniciaculin A.

Ubiquinone mimics known as quinone outside inhibitors (QoIs) are one of the most prominent fungicides used to protect crops in the agricultural industry. Due to chemotype similarities with known QoIs, peniciaculin A, a triaryl natural product, was proposed to exhibit similar broad spectrum antifungal activity against phytopathogens. Instability of the tertiary alcohol and phenol motif, however, prompted exploration of the antifungal properties of simplified analogues to probe possible overlap in mechanism of action between the natural product and QoIs.

Dynamic changes in proresolving lipid mediators and their receptors following acute vascular injury in male rats.

Acute vascular injury provokes an inflammatory response, resulting in neointimal hyperplasia (NIH) and downstream pathologies. The resolution of inflammation is an active process in which specialized proresolving lipid mediators (SPM) and their receptors play a central role. We sought to examine the acute phase response of SPM and their receptors in both circulating blood and the arterial wall in a rat angioplasty model.

Establishment of a human induced pluripotent stem cell line (ABi004-A) carrying a compound heterozygous mutation in the KCNV2 gene.

Pathogenic variants in the KCNV2 gene can cause a rare retinal dystrophy that can be inherited recessively, known as cone dystrophy with supernormal rod response (CDSRR). CDSRR leads to specific changes in photoreceptors' electroretinogram response, especially in the rods, poor visual acuity, photophobia, and even maculopathy. The derived iPSC lines from patients with CDSRR may pave the way for apprehension of the pathogenetic mechanism and drug development using in vitro models.

Assessing genomics confidence and learning needs in Australian nurses and midwives: an educational program evaluation.

The mainstreaming of genomics across healthcare specialties necessitates that all nurses and midwives have a high literacy in genomics. We aimed to design, develop, implement and evaluate a genomics education workshop for nurses and midwives using action research principles. Registered nurses and midwives completed an online survey regarding genomics confidence and learning needs (n = 274).

Inulin-gel-based oral immunotherapy remodels the small intestinal microbiome and suppresses food allergy.

Despite the potential of oral immunotherapy against food allergy, adverse reactions and loss of desensitization hinder its clinical uptake. Dysbiosis of the gut microbiota is implicated in the increasing prevalence of food allergy, which will need to be regulated to enable for an effective oral immunotherapy against food allergy. Here we report an inulin gel formulated with an allergen that normalizes the dysregulated ileal microbiota and metabolites in allergic mice, establishes allergen-specific oral tolerance and achieves robust oral immunotherapy efficacy with sustained unresponsiveness in food allergy models.

Intra-arterial Pressure-Enabled Drug Delivery Significantly Increases Penetration of Glass Microspheres in a Porcine Liver Tumor Model.

Purpose: To test the hypothesis that Pressure-Enabled Drug Delivery (PEDD) would improve the delivery of surrogate therapeutic glass microspheres (GMs) via hepatic artery infusion to liver tumors when compared with a conventional endhole microcatheter.

Materials And Methods: The study was conducted in transgenic pigs (Oncopigs) with induced liver tumors. Tumors were infused intra-arterially with fluorescently labeled GM.

Sweet corn phytoglycogen dendrimers as a lyoprotectant for dry-state protein storage.

Protein biotherapeutics typically require expensive cold-chain storage to maintain their fold and function. Packaging proteins in the dry state via lyophilization can reduce these cold-chain requirements. However, formulating proteins for lyophilization often requires extensive optimization of excipients that both maintain the protein folded state during freezing and drying (i.

Chimeric antigen receptor macrophages target and resorb amyloid plaques.

Substantial evidence suggests a role for immunotherapy in treating Alzheimer's disease (AD). While the precise pathophysiology of AD is incompletely understood, clinical trials of antibodies targeting aggregated forms of β amyloid (Aβ) have shown that reducing amyloid plaques can mitigate cognitive decline in patients with early-stage AD. Here, we describe what we believe to be a novel approach to target and degrade amyloid plaques by genetically engineering macrophages to express an Aβ-targeting chimeric antigen receptor (CAR-Ms).

Association between underweight status and chylothorax after esophagectomy for esophageal cancer: A propensity score-matched analysis.

Objective: To use a nationwide database of hospitalizations to investigate underweight status as a risk factor for postesophagectomy complications.

Methods: We identified all patients who underwent esophagectomy with a diagnosis of esophageal cancer and known body mass index in the 2018-2020 Nationwide Readmissions Database. All hospital visits for esophagectomy and within 30 days of initial discharge were analyzed for postoperative complications, including chylothorax.

Real-world evidence of Pressure-Enabled Drug Delivery for trans-arterial chemoembolization and radioembolization among patients with hepatocellular carcinoma and liver metastases.

Objectives: Pressure-Enabled Drug Delivery (PEDD), a method using pressure to advance catheter-delivered drug distribution, can improve treatment for hepatocellular carcinoma (HCC) and liver metastases, but real-world evidence is limited. We compared baseline patient characteristics, clinical complexity, and post-procedure healthcare resource utilization (HRUs) and clinical complications for PEDD and non-PEDD procedures.

Methods: This study used a retrospective, longitudinal, cohort design of claims data from Clarivate's Real World Data Repository, which includes 98% of US payers with over 300 million unique patients from all US states.
