We perform a large-scale randomized controlled trial to evaluate the potential of machine learning-based instruction sequencing to improve memorization while allowing the learners the freedom to choose their review times. After controlling for the length and frequency of study, we find that learners for whom a machine learning algorithm determines which questions to include in their study sessions remember the content over ~69% longer. We also find that the sequencing algorithm has an effect on users' engagement.

Background: Increasing evidence suggests a potential role of the gut microbiota in Parkinson's disease (PD). However, the relationship between the gut microbiome (GM) and PD dementia (PDD) remains debated, with their causal effects and underlying mechanisms not yet fully understood.
Methods: Utilizing data from large-scale genome-wide association studies (GWASs), this study applied bidirectional and mediating Mendelian randomization (MR) to investigate the causal relationship and underlying mechanisms between the GM and PDD.

Pretraining plays a pivotal role in acquiring generalized knowledge from large-scale data, achieving remarkable successes as evidenced by large models in CV and NLP. However, progress in the graph domain remains limited due to fundamental challenges represented by feature heterogeneity and structural heterogeneity. Recent efforts have been made to address feature heterogeneity via Large Language Models (LLMs) on text-attributed graphs (TAGs) by generating fixed-length text representations as node features.

Background Delirium and sleep disturbances are common in critically ill patients and are associated with adverse outcomes, including prolonged intensive care unit (ICU) stays. Ramelteon, a melatonin receptor agonist, may improve sleep and reduce delirium by regulating circadian rhythms. This study evaluated the efficacy of ramelteon in shortening ICU stay, decreasing delirium incidence and duration, and improving sleep quality in critically ill patients.

Background: There is growing evidence that Sjögren's syndrome (SS) and atherosclerosis (AS) might share underlying immunological and inflammatory processes. Observational data have pointed toward a potential association between SS and a heightened likelihood of developing AS, though the causal direction and specific dynamics of this relationship have not been clearly verified. This Mendelian randomization (MR) investigation opts to investigate potential bidirectional causality between SS and three types of AS: coronary, cerebral, and peripheral.

Background: Olfactory training (OT) has been proposed as a non-pharmacological intervention to improve cognitive functions and depressive symptomatology, but evidence remains fragmented.
Methods: In this study, we conducted a systematic review and meta-analysis of randomised controlled trials (RCTs) comparing OT versus control in middle-aged and elderly adults. Four databases (PubMed, Cochrane Library, Web of Science, Embase) were systematically searched from database inception through June 2025.
