EMERGENT RELATIONS AND COMPETING BEHAVIOR: EFFECTS ON INTERRUPTIONS, ACCURACY AND REACTION TIME.

This study investigated the impact of engaging in concurrent behaviors on the emergence of untrained stimulus-stimulus relations, specifically examining interruptions, accuracy, and reaction times during test. Six participants completed a computerized matching-to-sample task under three conditions: a baseline condition, a singing condition hypothesized to be incompatible with covert verbal behavior, and a foot tapping condition hypothesized to be compatible with covert verbal behavior. The tempo was kept consistent across both singing and foot tapping tasks.

Contour uncertainty assessment for MD-omitted daily adaptive online head and neck radiotherapy.

Background And Purpose: Daily online adaptive radiotherapy (DART) increases treatment accuracy by crafting daily customized plans that adjust to the patient's daily setup and anatomy. The routine application of DART is limited by its resource-intensive processes. This study proposes a novel DART strategy for head and neck squamous cell carcinoma (HNSCC), automizing the process by propagating physician-edited treatment contours for each fraction.

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.

Laser-Driven Dissection Achieves Earlier Continence Recovery Than Blunt Dissection During Holmium Laser Enucleation of the Prostate.

Objectives: During holmium laser enucleation of the prostate (HOLEP), blunt dissection (BD) by pushing the tip of the scope may exert mechanical force on the sphincter that could be avoided by adopting laser dissection (LD). This study evaluates the continence recovery in consecutive patients who underwent BD and LD.

Methods: A prospective cohort of patients who underwent LD was compared with a retrospective control that underwent BD.

Global Epidemiology of Alcohol-Related Liver Disease, Liver Cancer, and Alcohol Use Disorder, 2000-2021.

Background/aims: Alcohol represents a leading burden of disease worldwide, including alcohol use disorder (AUD) and alcohol-related liver disease (ALD). We aim to assess the global burden of AUD, ALD, and alcohol-attributable primary liver cancer between 2000-2021.

Methods: We registered the global and regional trends of AUD, ALD, and alcohol-related liver cancer using data from the Global Burden of Disease 2021 Study, the largest and most up-to-date global epidemiology database.

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.

Short-term Postoperative Complications of Lymphatic Malformation Surgical Excision: A 20-Year Institutional Review.

Objective: To evaluate outcomes and postoperative complications following surgical resection of lymphatic malformations (LMs) at a single multidisciplinary vascular anomalies center.

Methods: A single-center retrospective review of all patients ≤21 years old who underwent surgical resection of a lymphatic malformation at a quaternary referral center with a multidisciplinary vascular anomalies team from 2004 to 2024. Data pertaining to postoperative outcomes and treatments was abstracted.

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.

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.

Association of Subcapsular Liver Hematoma With Preeclampsia, Eclampsia, or Hemolysis, Elevated Liver Enzymes, and Low Platelet Count Syndrome.

Objective: To describe the presentation, outcomes, and management strategies for cases of subcapsular liver hematoma associated with preeclampsia, eclampsia, or HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome.

Methods: This was a case series of individuals with subcapsular liver hematoma managed at a single level IV center over a 10-year period, from 2013 to 2024. Presenting signs and symptoms, laboratory findings, time of onset, management strategies, acute perinatal and maternal outcomes, and long-term outcomes such as subsequent pregnancies were reviewed in the medical record and recorded.

A shared serial order system for verbal working memory and language production: evidence from aphasia.

Many aspects of human performance require producing sequences of items in serial order. The current study takes a multiple-case approach to investigate whether the system responsible for serial order is shared across cognitive domains, focusing on working memory (WM) and word production. Serial order performance in three individuals with post-stroke language and verbal WM disorders (hereafter persons with aphasia, PWAs) were assessed using recognition and recall tasks for verbal and visuospatial WM, as well as error analyses in spoken and written production tasks to assess whether there was a tendency to produce the correct phonemes/letters in the wrong order.

Changes in Emergency Department Practices After Implementation of a Standardized Heavy Menstrual Bleeding Guideline.

Objective: The aim of the study is to assess the effect of an emergency department (ED) standardized clinical guideline for adolescent heavy menstrual bleeding on the rate of return ED visits and ED provider history-taking and management of this condition.

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.

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.

Incidence and influential factors of postoperative pruritus in morphine-based intravenous patient-controlled analgesia.

Background: Pruritus is a distressing symptom of systemic opioid analgesia that responds poorly to conventional antipruritus treatments. This study aimed to determine the incidence and risk factors for postoperative pruritus using intravenous patient-controlled analgesia (IV-PCA).

Methods: Opioid-naïve patients who underwent morphine-based IV-PCA for postoperative pain at a tertiary center between January 1, 2020, and June 30, 2023, were included retrospectively.

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.

Disparities in Skin Cancer Outcomes in the Latine/Hispanic Population.

Despite having an overall lower lifetime risk for skin cancer, Latine/Hispanic individuals experience increased morbidity and mortality in skin cancer outcomes compared to non-Hispanic White individuals. The reasons for these disparate outcomes are multifactorial, but challenges in early skin cancer detection, limited awareness of risks, and inequitable access to care and/or treatment among this patient population likely are contributory. In this article, we review cutaneous malignancies in the Latine/Hispanic population and explore factors that impact overall prognosis, including unique clinical features, inadequate health coverage, medical mistrust, language barriers, differing cultural perspectives, and inadequate research.
