Prospective and retrospective analysis of whole slide images of sentinel and targeted lymph node frozen sections in breast cancer.

Different types of digital modalities are currently available for frozen section (FS) evaluation in surgical pathology practice. However, there are limited studies that demonstrate the potential of whole slide imaging (WSI) as a robust digital pathology option for FS FS diagnosis. In the current study, we compared the diagnostic accuracy achieved with WSI to that achieved with Light Microscopy (LM) for evaluating FSs of axillary sentinel lymph nodes (SLNs) and clipped lymph nodes (LNs) from breast cancer patients using two modalities.

The trait-specific timing of accelerated genomic change in the human lineage.

Humans exhibit distinct characteristics compared to our primate and ancient hominin ancestors. To investigate genomic bursts in the evolution of these traits, we use two complementary approaches to examine enrichment among genome-wide association study loci spanning diseases and AI-based image-derived brain, heart, and skeletal tissue phenotypes with genomic regions reflecting four evolutionary divergence points. These regions cover epigenetic differences among humans and rhesus macaques, human accelerated regions (HARs), ancient selective sweeps, and Neanderthal-introgressed alleles.

DNA damage and its links to neuronal aging and degeneration.

DNA damage is a major risk factor for the decline of neuronal functions with age and in neurodegenerative diseases. While how DNA damage causes neurodegeneration is still being investigated, innovations over the past decade have provided significant insights into this issue. Breakthroughs in next-generation sequencing methods have begun to reveal the characteristics of neuronal DNA damage hotspots and the causes of DNA damage.

Wip1 phosphatase activator QGC-8-52 specifically sensitizes p53-negative cancer cells to chemotherapy while protecting normal cells.

PP2C serine-threonine phosphatase Wip1 plays an important role in normal tissue homeostasis, stress signaling and pathogenesis of various human diseases. It is an attractive drug target for cancer treatment and inhibition of its expression or activity constitute a novel therapeutic intervention strategy to prevent the development of various cancers. However, previous strategies for Wip1 suppression may be ineffective in cancers lacking p53.

Ferumoxytol-enhanced MRI of retroplacental clear space disruption in placenta accreta spectrum.

Introduction: Placenta accreta spectrum (PAS) occurs when the placenta is pathologically adherent to the myometrium. An intact retroplacental clear space (RPCS) is a marker of normal placentation. In this study, we investigate use of the FDA-approved iron supplement ferumoxytol for contrast-enhanced MRI of the RPCS in mouse models of normal pregnancy and PAS.

Untargeted metabolomics analysis as a potential screening tool for 3-methylglutaconic aciduria syndromes.

The 3-methylglutaconic aciduria (3-MGA-uria) syndromes comprise a heterogeneous group of inborn errors of metabolism defined biochemically by detectable elevation of 3-methylglutaconic acid (3-MGA) in the urine. In type 1 (or primary) 3-MGA-uria, distal defects in the leucine catabolism pathway directly cause this elevation. Secondary 3-MGA-uria syndromes, however, are unrelated to leucine metabolism-specific defects but share a common biochemical phenotype of elevated 3-MGA.

Assessing the presence of rhinological surgery on social media: Factors influencing searches.

Objective: To evaluate the quality and engagement of rhinology-related educational videos shared by healthcare providers on Instagram.

Methods: The top 150 videos on Instagram for #SinusSurgeryEducation, #TurbinateReductionEducation, and #SeptoplastyEducation were selected. Videos were categorized by provider's specialty and analyzed for engagement metrics (likes, comments, shares, views), video duration, and hashtags.

A longitudinal examination of factors predicting maternal permissiveness toward underage student drinking across the first three years of college.

Parental permissiveness of drinking is a reliable predictor of college drinking, but there is little known about factors that predict such permissiveness. This study seeks to examine factors that predict two potentially different facets of permissiveness: perceived general approval of alcohol use and perceived drinking limits. Additionally, we explored how these facets mediate the relationship between the predictors of permissiveness and subsequent college drinking and related consequences.

Efficient activation of peroxymonosulfate by MoTiCT@Co for sustained emerging micropollutant removal: Mo vacancy-mediated activation in Fenton-like reactions.

Developing advanced heterogeneous catalysts through structural modifications effectively enhances the catalytic activity of non-homogeneous catalysts for removing emerging micropollutants (EMPs). In this study, MoTiCT@Co with Mo vacancies was synthesized using the Lewis molten salt method, which efficiently activates peroxymonosulfate (PMS) and continuously degrades EMPs in water. The abundant Mo vacancy structure in the material acts as an anchoring site for Co nanoparticles and a co-catalytic site for Fenton-like reactions, enabling PMS adsorption and activation.

Itaconate drives pro-inflammatory responses through proteasomal degradation of GLO1.

Itaconate is a small-molecule metabolite generated by the enzyme aconitate decarboxylase 1 (ACOD1), which is upregulated during inflammation. Traditionally, itaconate has been recognized for its anti-inflammatory properties; however, this study reveals a pro-inflammatory mechanism of itaconate in macrophages. We demonstrate that itaconate promotes the proteasomal degradation of glyoxalase 1 (GLO1) via Cys139.

A phase I study of temsirolimus in combination with metformin in patients with advanced or recurrent endometrial cancer.

Introduction: Molecular alterations in the PI3K/AKT and Ras/Raf/MEK/ERK pathways are frequently observed in patients with endometrial cancers. However, mTOR inhibitors, such as temsirolimus, have modest clinical benefits. In addition to inducing metabolic changes in cells, metformin activates AMPK, which in turn inhibits the mTOR pathway.

Silacrown ethers as ion transport modifiers and preliminary observations of cardiovascular cell line response.

Crown ethers have been shown to have physiological effects ascribed to their ionophoric properties. However, high levels of toxicity precluded interest in their evaluation as therapeutic agents. We prepared new silacrown analogs of crown ethers.

User Outcomes for an App-Delivered Hypnosis Intervention for Menopausal Hot Flashes: Retrospective Analysis.

Background: Hypnotherapy has been shown to be a safe, nonhormonal intervention effective for treating menopausal hot flashes. However, women experiencing hot flashes may face accessibility barriers to in-person hypnotherapy. To solve this issue, a smartphone app has been created to deliver hypnotherapy.

Methods: This was a retrospective cohort study. Patients less than 18 years old presenting to a single academic children's hospital ED between 2010 and 2020 with a chief complaint of heavy menstrual bleeding were included.

Surgical Site Infection After Sacral Neuromodulation: Impact of Postoperative Antibiotics.

Importance: There are limited data to guide practices to reduce surgical site infections following sacral neuromodulation; however, many surgeons prescribe prophylactic postoperative antibiotics after device implantation.

Objective: The aim of the study was to compare the proportion of patients with sacral neuromodulation device-associated surgical site infections after use of prophylactic postoperative antibiotics versus none.

Study Design: This was a multicenter retrospective cohort study of patients undergoing sacral neuromodulation device implantation at 11 institutions from January 2014 to December 2023, comparing outcomes in patients who did versus did not receive prophylactic postoperative antibiotic treatment.

Effects of F1-F2 Frequency Spacing on Spectral Integration in Combined Electric and Acoustic Stimulation.

Purpose: The aim of this study was to measure the effects of frequency spacing (i.e., F2 minus F1) on spectral integration for vowel perception in simulated bilateral electric-acoustic stimulation (BiEAS), electric-acoustic stimulation (EAS), and bimodal hearing.

Sleep Deprivation Elevates Resting and Exercise Blood Pressures and Augments Pressor Response at Exercise Onset.

Purpose: Sleep deprivation and elevated blood pressure (BP) increase the risk of cardiovascular diseases. However, the effects of sleep deprivation on BP response, especially at exercise onset remain unclear. We aimed to elucidate the effects of experimental sleep deprivation (ESD) on resting and exercise BPs, including that at exercise onset, and investigate whether a night-time nap during ESD changes the ESD-altered BP.

Hepatic Arterial Infusion Pump Complication With Multimodal Radiologic and Anatomic Review.

Hepatic arterial infusion therapy involves surgically implanting a subcutaneous hepatic arterial infusion pump with the catheter tip at the hepatic artery. This pump directly delivers chemotherapy to the liver, which may reduce systemic toxicity, improve resectability, and treat unresectable hepatic lesions. This therapy is used in primary or metastatic hepatic malignancies.

Application of Reverse Sural Flaps in Pediatric Patients: A Systematic Review.

Introduction: The reverse sural flap (RSF) is a random-type, pedicled flap based on sural artery perforators indicated for traumatic lower-extremity wounds. The RSF has demonstrated comparable results to free flap placement in the adult population for reconstruction of distal third defects, but few reports describe its application and outcomes in the pediatric population.

Methods: We investigated RSF application in pediatric patients (<18 years of age) through systematic review and meta-analysis.

Expanding the Range of Epithelial Marker and SMA Staining of Superficial CD34+ Fibroblastic Tumors: A Case Report and Review of the Literature.

Superficial CD34+ fibroblastic tumor (SCD34FT) is a relatively recently described borderline mesenchymal neoplasm. Owing to a relative lack of specificity in clinical presentation, radiopathologic findings, and immunohistochemical staining, the diagnoses of SCD34FT can be challenging. In this study, we present a case of a 55-year-old woman with an indolent painless nodule on the right shin.

Sociodemographic Disparities in the Use of Hospice by U.S. Nursing Home Residents: A Systematic Review.

Hospice can improve end-of-life (EOL) outcomes in U.S. nursing homes (NHs).

Superstable lipid vacuoles endow cartilage with its shape and biomechanics.

Conventionally, the size, shape, and biomechanics of cartilages are determined by their voluminous extracellular matrix. By contrast, we found that multiple murine cartilages consist of lipid-filled cells called lipochondrocytes. Despite resembling adipocytes, lipochondrocytes were molecularly distinct and produced lipids exclusively through de novo lipogenesis.

Biophysical and biochemical evidence for the role of acetate kinases (AckAs) in an acetogenic pathway in pathogenic spirochetes.

Unraveling the metabolism of Treponema pallidum is a key component to understanding the pathogenesis of the human disease that it causes, syphilis. For decades, it was assumed that glucose was the sole carbon/energy source for this parasitic spirochete. But the lack of citric-acid-cycle enzymes suggested that alternative sources could be utilized, especially in microaerophilic host environments where glycolysis should not be robust.
