Germ cell tumors in children.

Virchows Arch

January 2025

Department of Pathology and Laboratory Medicine, University of Miami Miller School of Medicine, Miami, FL, USA.

Pediatric germ cell tumors represent a rare but biologically diverse group of neoplasms arising from pluripotent primordial germ cells. The 2022 edition of the WHO Classification of Pediatric Tumors introduced the first organ independent classification of germ cell tumors, reflecting advances in molecular biology, histopathology, and clinical practice. This review highlights the key changes, including the refined distinctions between the different subtypes.

Resting-state functional connectivity analyses have been used to examine synchrony in neural networks in substance use disorders (SUDs), with the default mode network (DMN) one of the most studied. Prior research has generally found less DMN synchrony during use and greater synchrony during cessation, although little research has utilized this method with opioid use. This study examined resting brain activity in treatment-seeking persons who use opioids at two points-when using opioids and when opioid-free-to determine whether the DMN exhibits different levels of connectivity during opioid use and cessation and whether differences in connectivity predict subsequent relapse.

Pulmonary fibrosis is a pathological manifestation that occurs upon lung injury and subsequence aberrant repair with poor prognosis. However, current treatment is limited and does not distinguish different disease stages. Here, we aimed to study the differential functions of Axl, a receptor tyrosine kinase expressing on both macrophages and fibroblasts, in the whole course of pulmonary fibrosis.

Background: Women with inflammatory bowel disease (IBD) face complexities of disease management during pregnancy and childbirth. Apprehension regarding vaginal delivery in pregnant individuals with IBD persists due to concern for perianal disease and perineal trauma. The incidence of poor wound healing after obstetric anal sphincter injury is approximately 4% in the general population.

Parent-child relationship quality has critical implications for parental emotional well-being across the lifespan. The present study assessed how relationship quality is related to daily encounters between parents and children, how those encounters are linked with parents' mood, and how these associations vary by age. Participants (N = 129, ages 33-91) reported baseline relationship quality with a total of 337 children (ages 1-69).

Research and theory document links between sacrifices and commitment in couples, yet the direction of effects remains unclear. Whereas interdependence theorists suggest that sacrifices help couples to build commitment, other scholars have suggested that being committed leads partners to sacrifice for each other. Nearly all research in this area has focused on men and women in different-gender relationships with each other.

Large language models (LLMs) offer promising applications in mental health care to address gaps in treatment and research. By leveraging clinical notes and transcripts as data, LLMs could improve diagnostics, monitoring, prevention, and treatment of mental health conditions. However, several challenges persist, including technical costs, literacy gaps, risk of biases, and inequalities in data representation.

Vet Clin North Am Food Anim Pract

January 2025

Department of Veterinary and Biomedical Sciences, Animal Disease Research and Diagnostic Laboratory, South Dakota State University, Brookings, SD 57007, USA.

Respiratory disease in cattle and small ruminants is caused by various factors, including inadequate biosecurity and biocontainment. Biosecurity and biocontainment depend on good husbandry. Testing on arrival and quarantining for 42 to 56 days could improve biosecurity.

Working memory needs pointers.

Trends Cogn Sci

January 2025

University of Chicago, Chicago, IL, USA.

Cognitive neuroscience has converged on a definition of working memory (WM) as a capacity-limited system that maintains highly accessible representations via stimulus-specific neural patterns. We argue that this standard definition may be incomplete. We highlight the fundamental need to recognize specific instances or tokens and to bind those tokens to the surrounding context.

Benign prostatic hyperplasia is a prevalent condition leading to male lower urinary tract symptoms (mLUTS), particularly in aging populations. Current management strategies-spanning watchful waiting, pharmaceutical therapy, and surgical interventions such as transurethral resection of the prostate-face significant limitations, including side effects, low adherence, and patient hesitancy toward invasive treatments. First-line interventional therapy (FIT) emerges as a novel paradigm bridging the gap between medications and surgery.

This review explores the applications of artificial intelligence and machine learning (AI/ML) in radiation oncology, focusing on computer vision (CV) and natural language processing (NLP) techniques. We examined CV-based AI/ML in digital pathology and radiomics, highlighting the prospective clinical studies demonstrating their utility. We also reviewed NLP-based AI/ML applications in clinical documentation analysis, knowledge assessment, and quality assurance.

Continuous vital sign monitoring of patients recovering from surgery on general wards: a narrative review.

Br J Anaesth

January 2025

Perioperative Outcomes and Informatics Collaborative, Winston-Salem, NC, USA; Outcomes Research Consortium, Houston, TX, USA; Department of Anesthesiology, Center of Anesthesiology and Intensive Care Medicine, University Medical Center Hamburg-Eppendorf, Hamburg, Germany.

Most postoperative deaths occur on general wards, often linked to complications associated with untreated changes in vital signs. Monitoring in these units is typically intermittent checks each shift or maximally every 4-6 h, which misses prolonged periods of subtle changes in physiology that can herald a critical downstream event. Continuous monitoring of vital signs is therefore intuitively necessary for patient safety.

Generative models have diverse applications, including language processing and birdsong analysis. In this study, we demonstrate how a statistical test, designed to prevent overgeneralization in sequence generation, can be used to infer minimal models for the syllable sequences in Bengalese finch songs. We focus on the partially observable Markov model (POMM), which consists of states and the probabilistic transitions between them.

Blunted sensitivity to ethanol's aversive effects can increase motivation to consume ethanol; yet, the neurobiological circuits responsible for encoding these aversive properties are not fully understood. Plasticity in cells projecting from the anterior insular cortex (aIC) to the basolateral amygdala (BLA) is critical for taste aversion learning and retrieval, suggesting this circuit's potential involvement in modulating the aversive properties of ethanol. Here, we tested the hypothesis that GABAergic currents onto aIC-BLA projections would be facilitated as a consequence of retrieval of an ethanol-conditioned taste aversion (CTA).
