Endoscopic ultrasound-guided fine-needle aspiration and fine-needle biopsy in the diagnosis of gastrointestinal lymphomas.

Introduction: The role of endoscopic ultrasound-guided fine-needle aspiration and fine-needle biopsy (EUS-FNA/B) in the clinical management of gastrointestinal lymphoma has not been extensively studied. This study investigates the use of EUS-FNA/B in the diagnosis of first-time and recurrent gastrointestinal lymphomas at a large academic institution.

Materials And Methods: A total of 40 patients who had final diagnosis of lymphoma according to the World Health Organization (WHO) classification of tumors of hematopoietic lymphoid tissues who underwent EUS-FNA/B were included in the study.

Effect of a minimum floor price law for tobacco products on tobacco sales in Oakland, California, USA: a synthetic difference-in-differences analysis.

Background: In May 2020, Oakland became the most populous city in California to implement a minimum floor price law (MFPL), requiring tobacco retailers to sell cigarettes and cigars at $8 or more per pack/package. Policy enforcement began in August 2020.

Methods: We estimated changes in cigarette and cigar prices and unit sales for Oakland versus a matched comparator during the first 20 months following MFPL implementation using a synthetic difference-in-differences approach.

Conscientious objection: a global health perspective.

Conscientious objection is a critical topic that has been sparsely discussed from a global health perspective, despite its special relevance to our inherently diverse field. In this Analysis paper, we argue that blanket prohibitions of a specific type of non-discriminatory conscientious objection are unjustified in the global health context. We begin both by introducing a nuanced account of conscience that is grounded in moral psychology and by providing an overview of discriminatory and non-discriminatory forms of objection.

Cost-effectiveness analysis of proactive home visits compared with site-based community health worker care on antenatal care outcomes in Mali: a cluster-randomised trial.

Introduction: Despite recommendations from the WHO, antenatal care (ANC) coverage remains low in many low-income and middle-income countries (LMICs). Community health workers (CHWs) can play an important role in expanding ANC coverage through pregnancy identification, provision of health education, screening for complications, delivery of therapeutic care and referral to higher levels of care. However, despite the success of CHW programmes in various countries, WHO has called for additional research to develop evidence-based models that optimise CHW service delivery and that can be replicated across geographies.

Microglia-like cells from patient monocytes demonstrate increased phagocytic activity in probable Alzheimer's disease.

Alzheimer's disease (AD) is a neurodegenerative disorder that is characterized by the accumulation of amyloid plaques, phosphorylated tau tangles and microglia toxicity, resulting in neuronal death and cognitive decline. Since microglia are recognized as one of the key players in the disease, it is crucial to understand how microglia operate in disease conditions and incorporate them into models. The studies on human microglia functions are thought to reflect the post-symptomatic stage of the disease.

Computational Pathology Detection of Hypoxia-Induced Morphological Changes in Breast Cancer.

Understanding the tumor hypoxic microenvironment is crucial for grasping tumor biology, clinical progression, and treatment responses. This study presents a novel application of AI in computational histopathology to evaluate hypoxia in breast cancer. Weakly Supervised Deep Learning (WSDL) models can accurately detect morphological changes associated with hypoxia in routine Hematoxylin and Eosin (H&E) whole slide images (WSI).

A3AR antagonism mitigates metabolic dysfunction-associated steatotic liver disease by exploiting monocyte-derived Kupffer cell necroptosis and inflammation resolution.

Background & Aims: Metabolic dysfunction-associated steatotic liver (MASLD) progression is driven by chronic inflammation and fibrosis, largely influenced by Kupffer cell (KC) dynamics, particularly replenishment of pro-inflammatory monocyte-derived KCs (MoKCs) due to increased death of embryo-derived KCs. Adenosine A3 receptor (A3AR) plays a key role in regulating metabolism and immune responses, making it a promising therapeutic target. This study aimed to investigate the impact of selective A3AR antagonism for regulation of replenished MoKCs, thereby improving MASLD.

Differential Efficacy of Advanced Therapies in Inducing Remission in Ulcerative Colitis Based on Prior Exposure to TNF Antagonists.

Background And Aims: We sought to ascertain how prior exposure to TNF antagonists impacts treatment response with various classes of advanced therapies in patients with ulcerative colitis (UC), through a systematic review and meta-analysis.

Methods: Through a systematic review of multiple databases through June 30, 2024, we identified 17 RCTs in 8871 adults with moderate-severe UC who were treated with different advanced therapies vs. placebo, and reported efficacy in induction of clinical remission, stratified by prior exposure to TNF antagonists.

Synergistic effects of immunotherapy and adjunctive therapies in prostate cancer management.

In recent years, cancer immunotherapy has received widespread attention due to significant tumor clearance in some malignancies. Various immunotherapy approaches, including vaccines, immune checkpoint inhibitors, oncolytic virotherapy, bispecific T cell engagers, and adoptive T cell transfer, have completed or are undergoing clinical trials for prostate cancer. Despite immune checkpoint blockade's extraordinary effectiveness in treating a variety of cancers, targeted prostate cancer treatment using the immune system is still in its infancy.

Regboost: Enhancing mouse brain image registration using geometric priors and Laplacian interpolation.

We show in this work that incorporating geometric features and geometry processing algorithms for mouse brain image registration broadens the applicability of registration algorithms and improves the registration accuracy of existing methods. We introduce the preprocessing and postprocessing steps in our proposed framework as RegBoost. We develop a method to align the axis of 3D image stacks by detecting the central planes that pass symmetrically through the image volumes.

No Difference in 2-year Outcomes for Non-Hypermobile Femoroacetabular Impingement Syndrome Patients Undergoing Hip Arthroscopy with and without Closure of Periportal Capsulotomy.

Purpose: To assess whether capsular closure during hip arthroscopy with periportal capsulotomy affects 2-year postoperative outcomes for femoroacetabular impingement syndrome (FAIS) patients without hypermobility.

Methods: A matched-cohort retrospective analysis of a single institutional database of patients who underwent hip arthroscopy with periportal capsulotomy for management of FAIS between 2014-2022 was performed. Study inclusion criteria consisted of FAIS patients who exhibited no signs of generalized ligamentous laxity (GLL) (Beighton score 0).

Shedding light on the role of complement C4 activation in cancer.

Complement C4 is a key component in the activation of classical and lectin complement pathways, which are observed in both animal tumor models and cancer patients. While its role in autoimmune disorders has been extensively studied, the functions of complement C4 and its activation in cancer have received inadequate consideration. Recent studies have detected C4 activation in animal tumor models and cancer patients, with its fragment C4d found in cancer tissues and lymph nodes.

Adolescents' perceptions, experiences, and reactions to "fake" vaping devices.

Unlabelled: Use of electronic cigarette (vaping) devices, whether to inhale nicotine, cannabis, or other substances, may pose health risks to adolescents. Those risks could be heightened when a vaping device is "fake," a term we use to include inauthentic, knockoff, counterfeit, and/or adulterated devices, an issue exemplified by the Electronic Cigarette, or Vaping, Product Use-Associated Lung Injury (EVALI) outbreak of 2019-2020.

Methods: Investigators completed in-depth, semi-structured interviews in 2020-2021 with 47 California adolescents (ages 13-17) who used nicotine products.

The effect of temporary CSF diversion modality on shunt-dependency following aneurysmal subarachnoid hemorrhage: A nationwide assessment.

Background: Aneurysmal subarachnoid hemorrhage (aSAH) carries a high economic cost and clinical morbidity in the United States. Beyond prolonged admissions and poor post-injury functional status, there is an additional cost of chronic shunt-dependent hydrocephalus for many aSAH patients. Adjuvant lumbar drain (LD) placement has been hypothesized to promote clearance of subarachnoid blood from the cisternal space, with an ultimate effect of decreasing shunt placement rates.

Testing the generalizability of minimal group attitudes in minority and majority race children.

The minimal group effect, in which people prefer ingroup members to outgroup members even when group membership is trivially constructed, has been studied extensively in psychological science. Despite a large body of literature on this phenomenon, concerns persist regarding previous developmental research populations that are small and lack racial/ethnic diversity. In addition, it remains unclear what role holding membership within and interacting with specific racial/ethnic groups plays in the development of children's group attitudes.

A spatial triage of at-risk conifer forests to support seed collection efforts and sustainable forestry.

At-risk conifer stands growing in hot, arid conditions at low elevations may contain the most climate change-adapted seeds needed for sustainable forestry. This study used a triage framework to identify high-priority survey areas for Pinus ponderosa (Pipo) within a large region, by intersecting an updated range map with a map of seed zones and elevation bands (SZEBs). The framework assesses place-based climate change and potential wildfire risks by rank-order across 740 potential collection units.

The blue-light receptor CRY1 serves as a switch to balance photosynthesis and plant defense.

Plant stomata open in response to blue light, allowing gas exchange and water transpiration. However, open stomata are potential entry points for pathogens. Whether plants can sense pathogens and mount defense responses upon stomatal opening and how blue-light cues are integrated to balance growth-defense trade-offs are poorly characterized.

Neurological and psychiatric characterization of rapid-onset dystonia-parkinsonism over time.

Introduction: The onset of symptoms in Rapid-onset dystonia-parkinsonism (RDP) is typically over days to weeks and is often triggered by stressors like fever or childbirth. Limited information is available on how the motor and nonmotor symptoms evolve over the course of the disease. Our longitudinal study analyzed data from a cohort of RDP patients, documenting their symptoms across multiple visits.

Omics-driven onboarding of the carotenoid producing red yeast Xanthophyllomyces dendrorhous CBS 6938.

Transcriptomics is a powerful approach for functional genomics and systems biology, yet it can also be used for genetic part discovery. Here, we derive constitutive and light-regulated promoters directly from transcriptomics data of the basidiomycete red yeast Xanthophyllomyces dendrorhous CBS 6938 (anamorph Phaffia rhodozyma) and use these promoters with other genetic elements to create a modular synthetic biology parts collection for this organism.
