Anti-inflammatory agents for the management of COPD - Quo Vadis?

Agamemnon Bakakos, Zoi Sotiropoulou, Nektarios Anagnostopoulos et al. · 2025 · Respiratory Medicine

Chronic obstructive pulmonary disease (COPD) remains a leading cause of morbidity and mortality around the globe. Its main characteristics are persistent respiratory symptoms and progressive airflow limitation, both of which are driven by chronic inflammation. Despite the use of maximum bronchodilation and in selected patients inhaled corticosteroids (ICS), current therapies neither halt disease progression nor prevent exacerbations and loss of lung function. Recent research has focused on developing novel anti-inflammatory agents targeting specific pathways implicated in COPD pathogenesis, ai

Examining human reliance on artificial intelligence in decision making

Jo Pearson, Itiel E. Dror, Emma Jayes et al. · 2026 · Scientific Reports

The use of Artificial Intelligence (AI) to effectively support human decision making depends on whether humans are willing to trust in, and thus rely on, AI. Understanding human reliance on AI is critical given controversial reports of AI inaccuracy and bias. Furthermore, the erroneous belief that using technology removes biases may lead to overreliance on AI. To examine humans’ reliance on AI, human participants (N = 295, Mage = 33.79) judged the authenticity of 80 faces (40 real, 40 AI-synthesized) presented alongside guidance supposedly from humans or from AI. This guidance was correct only

Gene therapy for Duchenne muscular dystrophy

Yuko Shimizu‐Motohashi · 2025 · Brain and Development

Duchenne muscular dystrophy (DMD) is an X-linked neuromuscular disorder caused by variants of the DMD that leads to progressive muscle degeneration. Recent advances in gene therapy have opened new therapeutic avenues, particularly through the use of adeno-associated virus (AAV)-mediated micro-dystrophin delivery. Delandistrogene moxeparvovec, the first FDA-approved gene therapy for DMD, has demonstrated transgene expression and potential functional improvement in early phase trials, although its long-term efficacy, durability, and safety remain unconfirmed. Immune-mediated toxicities including

Kriging prior regression: A case for kriging-based spatial features with TabPFN in soil mapping

Jonas Schmidinger, Viacheslav Barkov, Sebastian Vogel et al. · 2025 · Computers and Electronics in Agriculture

Machine learning and geostatistics are two fundamentally different frameworks for the prediction and spatial mapping of soil properties. Geostatistics leverages the spatial structure of soil properties, whereas machine learning models capture the relationship between available environmental features and soil properties. We propose a hybrid framework that augments machine learning with spatial context through the engineering of ‘spatial lag’ features derived from ordinary kriging. We call this approach ‘kriging prior regression’ (KpR), as it reverses the logic of regression kriging by incorpera

Apology Cost Is More Strongly Associated With Perceived Sincerity Than Forgiveness

Yohsuke Ohtsubo, Miyu Higuchi · 2022 · Letters on Evolutionary Behavioral Science

This study aimed at replicating a previously reported pattern: costly apologies are perceived as more sincere than non-costly apologies even when the transgression was unintentional, while costly apologies do not foster forgiveness more than non-costly apologies when the transgression was unintentional. We conducted a vignette study with a 2 (apology cost: costly vs. non-costly) × 3 (intention: no vs. ambiguous vs. malicious intention) between-participants factorial design. We failed to replicate the aforementioned pattern. Instead, we found that costly apologies promote not only perceived sin

Revealing the χ eff–q Correlation among Coalescing Binary Black Holes and Tentative Evidence for AGN-driven Hierarchical Mergers

Yin-Jie Li, Yuan-Zhu Wang, Shao-Peng Tang et al. · 2025 · The Astrophysical Journal

Abstract The origin of the correlation between the effective spins ( χ eff ) and mass ratios ( q ) of LIGO–Virgo–KAGRA’s binary black holes (BBHs) is still an open question. Motivated by the recent identification of two subpopulations of the BBHs, in this work we investigate the potential χ eff – q correlation for each subpopulation. Surprisingly, the χ eff – q correlation either significantly weakens or disappears for the low-mass subpopulation if we introduce a second χ eff distribution for the high-mass subpopulation, which likely originates from hierarchical mergers. This suggests that the

Comparative analysis of supervised and self-supervised learning with small and imbalanced medical imaging datasets

Andrea Espis, Chiara Marzi, Stefano Diciotti · 2025 · Scientific Reports

Self-supervised learning (SSL) in computer vision has shown its potential to reduce reliance on labeled data. However, most studies focused on balanced, large, broad-domain datasets like ImageNet, whereas, in real-world medical applications, dataset size is typically limited. This study compares the performance of SSL versus supervised learning (SL) on small, imbalanced medical imaging datasets. We experimented with four binary classification tasks: age prediction and diagnosis of Alzheimer's disease from brain magnetic resonance imaging scans, pneumonia from chest radiograms, and retinal dise

SGLT-2 Inhibitors and GLP-1 Receptor Agonists as Combination Therapy in Type 2 Diabetes

Aris Liakos, Thomas Karagiannis, Ioannis Avgerinos et al. · 2026 · Current Diabetes Reports

PURPOSE OF REVIEW: The pharmacologic management of type 2 diabetes prioritises sodium-glucose cotransporter 2 (SGLT-2) inhibitors or glucagon-like peptide 1 (GLP-1) receptor agonists for their demonstrated cardiovascular benefits in individuals with atherosclerotic cardiovascular disease or multiple cardiovascular risk factors, chronic kidney disease, and heart failure. However, while current guidelines recommend these drug classes alone, combination therapy is not explicitly advocated. Herein we summarise the rationale and available evidence in support for combination therapy. RECENT FINDINGS

Improving medication adherence in type 2 diabetes: strategies for better clinical and economic outcomes

Patrick Highton, Mark P. Funnell, Pankaj Gupta et al. · 2025 · Diabetologia

Abstract Medication adherence is critical for optimal glycaemic management and the prevention of complications in type 2 diabetes mellitus. Despite its importance, non-adherence remains a prevalent issue, with global estimates suggesting that approximately 38% of people with type 2 diabetes do not take their medications as prescribed, although estimates vary widely due to a range of patient-related, socioeconomic, condition-related (e.g. chronicity, severity of comorbidities) and healthcare system factors. This review synthesises the current evidence on the prevalence of non-adherence in type

Subbasin Spatial Scale Effects on Hydrological Model Prediction Uncertainty of Extreme Stream Flows in the Omo Gibe River Basin, Ethiopia

Bahru M. Gebeyehu, Asie k. Jabir, Getachew Tegegne et al. · 2023 · Remote Sensing

Quantification of hydrologic model prediction uncertainty for various flow quantiles is of great importance for water resource planning and management. Thus, this study is designed to assess the effect of subbasin spatial scale on the hydrological model prediction uncertainty for different flow quantiles. The Soil Water Assessment Tool (SWAT), a geographic information system (GIS) interfaced hydrological model, was used in this study. Here, the spatial variations within the sub-basins of the Omo Gibe River basin in Ethiopia’s Abelti, Wabi, and Gecha watersheds from 1989 to 2020 were examined.

Cognitive load, fatigue and aversive simulator symptoms but not manipulated zeitgebers affect duration perception in virtual reality

Magdalena Sabat, Bartosz Haładus, Michał Klincewicz et al. · 2022 · Scientific Reports

The perceived duration of an interval depends on numerous aspects of the passed event both endogenous, including physiological arousal, level of wakefulness, attention, and surprise, as well as exogenous such as valence, salience, or context in the environment. There is some evidence that "time-giving" cues from the environment (zeitgebers) are coupled with time perception. The movement of the sun on the horizon was demonstrated to affect interval perception in a study conducted by Schatzschneider et al. (2016) claiming that the sun's motion is a zeitgeber that influences time perception. In t

Robustness of the rule‐learning effect in 7‐month‐old infants: A close, multicenter replication of Marcus et al. (1999)

Andreea Geambașu, Sybren Spit, Daan van Renswoude et al. · 2022 · Developmental Science

We conducted a close replication of the seminal work by Marcus and colleagues from 1999, which showed that after a brief auditory exposure phase, 7-month-old infants were able to learn and generalize a rule to novel syllables not previously present in the exposure phase. This work became the foundation for the theoretical framework by which we assume that infants are able to learn abstract representations and generalize linguistic rules. While some extensions on the original work have shown evidence of rule learning, the outcomes are mixed, and an exact replication of Marcus et al.'s study has

When Do Low-Frequency Measures Really Measure Effective Spreads? Evidence from Equity and Foreign Exchange Markets

Mohammad R. Jahan‐Parvar, Filip Žikeš · 2023 · Review of Financial Studies

Abstract We present evidence that several popular low-frequency measures of effective spread suffer from a volatility-induced bias and that volatility is the primary driver of the variation of these liquidity proxies. Using data for U.S. equities and major foreign exchange rates, we show that the bias arises when the effective spread is small relative to volatility. We document that the bias has become more acute over time and show that volatility-biased measures fail to replicate some well-known results in empirical finance. We conclude by providing guidance on the choice of low-frequency mea
