Measuring the effects of motion corruption in fetal fMRI.

Irregular and unpredictable fetal movement is the most common cause of artifacts in in utero functional magnetic resonance imaging (fMRI), affecting analysis and limiting our understanding of early functional brain development. The accurate detection of corrupted functional connectivity (FC) resulting from motion artifacts or preprocessing, instead of neural activity, is a prerequisite for reliable and valid analysis of FC and early brain development. Approaches to address this problem in adult data are of limited utility in fetal fMRI.

Pregnancy and cardiovascular outcomes among patients post Fontan surgery: a 25-year single-centre retrospective cohort study.

Introduction: Data on the characteristics and outcomes of pregnancy and among patients with Fontan physiology are limited. We aimed to evaluate the immediate and long-term outcomes among these patients who were followed at our centre.

Methods: We included adult patients who had undergone Fontan surgery for congenital heart disease and were pregnant between 1994 and 2021.

Performance of ChatGPT-4o in the diagnostic workup of fever among returning travelers requiring hospitalization: a validation study.

Background: Febrile illness in returned travelers presents a diagnostic challenge in non-endemic settings. Chat generative pretrained transformer (ChatGPT) has the potential to assist in medical tasks, yet its diagnostic performance in clinical settings has rarely been evaluated. We conducted a preliminary validation assessment of ChatGPT-4o's performance in the workup of fever in returning travelers.

From treetops to river bottoms: Exploring the role of phyllosphere fungi in aquatic fungal communities.

Fungi play a crucial role in aquatic leaf litter decomposition. Aquatic fungi have long been thought to spend the majority of their lives in the water. Here, we explore the possibility of an amphibious life cycle, where phyllosphere fungi spend part of their life cycle in aquatic systems.

Frontal Paraventricular Cysts: Refined Definitions and Outcomes.

Background And Purpose: Frontal paraventricular cystic changes have a varied etiology that includes connatal cysts, subependymal pseudocysts, necrosis, and enlarged perivascular spaces. These may be difficult to distinguish by neuroimaging and have a variety of associated prognoses. We aim to refine the neuroimaging definition of frontal horn cysts and correlate it with adverse clinical conditions.
