Clinicopathological features and outcome for neuroendocrine neoplasms of gastroesophageal junction: A population‐based study

Panpan Zhang, Wei Wang, Ming Lu et al. · 2018 · Cancer Medicine

BACKGROUND: Gastroesophageal Junction neuroendocrine neoplasms (GEJ-NENs) are rare and heterogeneous tumors. We aim to analyze the clinicopathlogical features and prognostic factors of GEJ-NENs and to compare the outcome of GEJ-NENs with other gastric NENs. METHODS: A total of 297 GEJ-NENs patients were enrolled from 10 Chinese hospitals and 3152 gastric NENs patients, including 274 GEJ-NENs, were retrieved from Surveillance, Epidemiology, and End Results (SEER) database. RESULTS: The clinical characteristics of GEJ-NENs among different races were different. All Chinese patients had GEJ-NENs o

Retrograde Interference in Perceptual Learning of a Peripheral Hyperacuity Task

Shao-Chin Hung, Aaron R. Seitz · 2011 · PLoS ONE

Consolidation, a process that stabilizes memory trace after initial acquisition, has been studied for over a century. A number of studies have shown that a skill or memory must be consolidated after acquisition so that it becomes resistant to interference from new information. Previous research found that training on a peripheral 3-dot hyperacuity task could retrogradely interfere with earlier training on the same task but with a mirrored stimulus configuration. However, a recent study failed to replicate this finding. Here we address the controversy by replicating both patterns of results, ho

Identifying statistically significant combinatorial markers for survival analysis

Raissa Relator, Aika Terada, Jun Sese · 2018 · BMC Medical Genomics

BACKGROUND: Survival analysis methods have been widely applied in different areas of health and medicine, spanning over varying events of interest and target diseases. They can be utilized to provide relationships between the survival time of individuals and factors of interest, rendering them useful in searching for biomarkers in diseases such as cancer. However, some disease progression can be very unpredictable because the conventional approaches have failed to consider multiple-marker interactions. An exponential increase in the number of candidate markers requires large correction factor

Rapid Integration of LLMs in Healthcare Raises Ethical Concerns: An Investigation into Deceptive Patterns in Social Robots

Robert Ranisch, Joschka Haltaufderheide · 2025 · Digital Society

Abstract Conversational agents are increasingly used in healthcare, with Large Language Models (LLMs) significantly enhancing their capabilities. When integrated into social robots, LLMs offer the potential for more natural interactions. However, while LLMs promise numerous benefits, they also raise critical ethical concerns, particularly regarding hallucinations and deceptive patterns. In this case study, we observed a critical pattern of deceptive behavior in commercially available LLM-based care software integrated into robots. The LLM-equipped robot falsely claimed to have medication remin

Cathepsins in Neurological Diseases

Dominik Lewandowski, Mateusz Konieczny, Agata Różycka et al. · 2025 · International Journal of Molecular Sciences

Cathepsins, a family of lysosomal proteases, play critical roles in maintaining cellular homeostasis through protein degradation and modulation of immune responses. In the central nervous system (CNS), their functions extend beyond classical proteolysis, influencing neuroinflammation, synaptic remodeling, and neurodegeneration. Emerging evidence underscores the crucial role of microglial cathepsins in the pathophysiology of several neurological disorders. This review synthesizes current knowledge on the involvement of cathepsins in a spectrum of CNS diseases, including Parkinson's disease, Alz

Wearable Devices in Remote Cardiac Rehabilitation With and Without Weekly Online Coaching for Patients With Coronary Artery Disease: Randomized Controlled Trial

Ryota Nishio, Tomotaka Dohi, Miho Yokoyama et al. · 2025 · JMIR mhealth and uhealth

Background: Cardiac rehabilitation (CR) is effective in preventing cardiovascular diseases; however, participation in CR programs remains limited due to the associated challenges. The integration of wearable devices and real-time monitoring offers a potential solution to enhance adherence to remote CR programs and their outcomes. Objective: This study aimed to evaluate the efficacy of a remote CR program using wearable devices and real-time monitoring with or without online coaching (OLC) in improving exercise capacity in patients with coronary artery disease (CAD).

Anatomic Risk Factors for Initial and Secondary Noncontact Anterior Cruciate Ligament Injury: A Prospective Cohort Study in 880 Female Elite Handball and Soccer Players

Yusuke Kamatsuki, Marie Synnøve Qvale, Kathrin Steffen et al. · 2024 · The American Journal of Sports Medicine

Background: Anterior cruciate ligament (ACL) injury is one of the most severe injuries for athletes. It is important to identify risk factors because a better understanding of injury causation can help inform athletes about risk and increase their understanding of and motivation for injury prevention. Purpose: To investigate the relationship between anatomic factors and risk for future noncontact ACL injuries. Study Design: Cohort study; Level of evidence, 2. Methods: A total of 870, excluding 9 players with a new contact ACL injury and a player with a new noncontact ACL injury just before the

Electrospun PLA/PVP K90 Biphasic-Release Sublingual Film for Motion Sickness Treatment

Wenwen Zhang, Qilin Wang, Wei Yi et al. · 2026 · Biomolecules

To overcome the limitations of traditional motion sickness medications—slow onset of action, short duration of efficacy, and poor patient compliance—this study employed coaxial electrospinning technology. Poly(lactic acid) (PLA) and polyvinylpyrrolidone K90 (PVP K90) were used as composite carrier materials. The sheath layer is composed of highly hydrophilic PVP K90, loaded with the antihistamine diphenhydramine (DPH). The core layer, composed of biodegradable PLA with excellent sustained-release properties, carries the anticholinergic drug scopolamine hydrobromide (SH). This core–sheath nanos

Crafting the wearable computer: Design process and user experience

Sarah Kettley · 2026 · Edinburgh Napier Research Repository (Edinburgh Napier University)

The purpose of the research described in this thesis was to develop a design methodology for Wearable Computing concepts that could potentially embody authenticity. The Wearables community, still firmly rooted in the disciplines of engineering and ergonomics, had made clear its aspirations to the mainstream market (DeVaul et al 2001). However, at this point, there was a distinct lack of qualitative studies on user perceptions of Wearable products. A review of the market research literature revealed significant consumer demand for authenticity in goods and services, and it was this need that dr

Doxycycline Use in Adolescent Psychiatric Patients and Risk of Schizophrenia: An Emulated Target Trial

Ulla Lång, Johanna Metsälä, Hugh Ramsay et al. · 2025 · American Journal of Psychiatry

OBJECTIVE: As many as half of individuals who develop psychosis had attended child and adolescent psychiatric services at some stage in childhood, highlighting substantial opportunities for prevention within these services if an effective preventive intervention were identified. The authors hypothesized that adolescent psychiatric patients exposed to doxycycline, an antibiotic with putative neuroprotective properties, would have a lower risk of developing schizophrenia. METHODS: This was an emulated target trial using nationwide Finnish health register data on all individuals born between 1987

Measuring Semantic Deviation: Operationalizations, Experiments, and Falsification Conditions for a Theory of Meaning as Field Deformation

Nobel Glas · 2026 · Zenodo (CERN European Organization for Nuclear Research)

EA-GLAS-02 v1.0. A self-contained empirical white paper presenting the measurement program for the Semantic Deviation Principle (Sharks 2026). Defines meaning as the time-integrated divergence a sign induces from the most probable trajectory of a semantic field, extending the Bar-Hillel and Carnap (1953) program into distributional and temporal domains. Two primary operationalizations. (F1) Closed-system trajectory deviation within a frozen language model, where the counterfactual baseline is read from logits, building on surprisal theory (Hale 2001; Levy 2008) and decomposing it into signed d
