Article Abstract

Aflatoxin M1 (AFM1) contamination in milk and dairy products poses a significant global concern due to its severe health risks to humans. Sensitive and specific detection of AFM1 has emerged as the most effective strategy for mitigating these health risks. Aptamers are regarded as ideal biorecognition elements for AFM1 monitoring owing to their small size, ease of production, excellent affinity and specificity, high stability, and low immunogenicity. Herein, we review the advancements in SELEX-based aptamer selection and the recent development of aptasensors for AFM1 from 2020 to 2025 for the first time. Additionally, the progress in signal transduction strategies, underlying mechanisms, and the design of portable devices are highlighted. Furthermore, we critically examine and summarize the prospects, challenges, and future trends in aptasensor technology, with a particular emphasis on its potential for real-world application and commercialization.

Background: Experience with icodextrin use in children on long-term peritoneal dialysis is limited. We describe international icodextrin prescription practices and their impact on clinical outcomes: ultrafiltration, blood pressure control, residual kidney function (RKF), technique and patient survival.

Methods: We included patients under 21 years enrolled in the International Pediatric Peritoneal Dialysis Network (IPPN) between 2007 and 2024, on automated PD with a daytime dwell.

Background: Following SARS-CoV-2 infection, ~10-35% of COVID-19 patients experience long COVID (LC), in which debilitating symptoms persist for at least three months. Elucidating biologic underpinnings of LC could identify therapeutic opportunities.

Methods: We utilized machine learning methods on biologic analytes provided over 12-months after hospital discharge from >500 COVID-19 patients in the IMPACC cohort to identify a multi-omics "recovery factor", trained on patient-reported physical function survey scores.

Climate change is expected to pose significant threats to public health, particularly vector-borne diseases. Despite dramatic recent increases in dengue that many anecdotally connect with climate change, the effect of anthropogenic climate change on dengue remains poorly quantified. To assess this link, we assembled local-level data on dengue across 21 countries in Asia and the Americas.

Increased adiposity and chronic psychosocial stress (CPS) are plausible modifiable contributors of the recent increase in early-onset colorectal cancer (EOCRC). We conducted an 8-week randomized controlled pilot trial evaluating the feasibility and acceptability of time restricted eating (TRE) (daily ad libitum eating between 12-8pm) and Mindfulness ("Mindfulness for Beginners" course from the Calm app) among young adults. Participants were randomized to the following groups: TRE ( = 10); Mindfulness ( = 11); TRE & Mindfulness ( = 11); or Control ( = 11).
