The critical dynamics of hippocampal seizures.

Nat Commun

August 2024

Center for experimental neurology, Sleep-wake epilepsy center, NeuroTec, Department of Neurology, Inselspital, University Hospital Bern, University of Bern, Bern, Switzerland.

Epilepsy is defined by the abrupt emergence of harmful seizures, but the nature of these regime shifts remains enigmatic. From the perspective of dynamical systems theory, such critical transitions occur upon inconspicuous perturbations in highly interconnected systems and can be modeled as mathematical bifurcations between alternative regimes. The predictability of critical transitions represents a major challenge, but the theory predicts the appearance of subtle dynamical signatures on the verge of instability.

Objectives: Sex differences occur in atrial fibrillation (AF), including age at first manifestation, pathophysiology, treatment allocation, complication rates and quality of life. However, optimal doses of cardiovascular pharmacotherapy used in women with AF with or without heart failure (HF) are unclear. We investigated sex-specific associations of beta-blocker and renin-angiotensin system (RAS) inhibitor doses with cardiovascular outcomes in patients with AF or AF with concomitant HF.

Article Synopsis
  • Physicians can use nystagmus fixation suppression to help diagnose acute vestibular syndrome, but the accuracy of detecting this suppression using simulations by doctors is limited.
  • In a study with 20 doctors, their ability to identify changes in nystagmus was tested under different conditions, revealing that both beginners and experienced physicians struggled similarly.
  • The results showed that small changes in nystagmus velocity were difficult to detect, especially when the baseline nystagmus was strong, indicating that clinical tests for this condition may benefit from additional technology, like video-oculography.

Article Synopsis
  • The study aimed to explore differences in characteristics and 2-year outcomes after surgical aortic valve replacement (SAVR) between males and females, using data from two registries involving 933 patients.
  • Females had certain clinical differences such as lower body mass index, higher surgical risk scores, and smaller valves compared to males, but these disparities largely disappeared after adjusting for similar baseline characteristics.
  • Ultimately, despite a higher initial surgical risk profile, both sexes had comparable outcomes 2 years post-SAVR, indicating no significant differences in overall results based on sex.

Prediction of plasma sodium changes in the acutely ill patients: the potential role of tissue sodium content.

Eur J Intern Med

November 2024

Amsterdam UMC location University of Amsterdam, Department of Internal Medicine Division of Nephrology, Amsterdam University Medical Centre, Location Academic Medical Centre, University of Amsterdam, Meibergdreef 9 PO Box 22660, 1100 DD, Amsterdam, The Netherlands; Amsterdam Cardiovascular Sciences, Microcirculation, Amsterdam, The Netherlands. Electronic address:

Background: Rapid correction of dysnatremias can result in neurological complications. Therefore, various formulas are available to predict changes in plasma sodium concentration ([Na]) after treatment, but these have been shown to be inaccurate. This could be explained by sodium acumulation in skin and muscle tissue, which is not explicitly considered in these formulas.

Article Synopsis
  • - The study examined if pain habituation measures could be potential indicators of central sensitization in chronic pain patients compared to healthy controls (HC), involving 93 patients and 60 controls and using contact-heat stimuli.
  • - Results showed no significant differences in pain habituation between chronic pain patients and HC, even in those with clear signs of central sensitization; however, patients had longer latencies in contact-heat evoked potentials (CHEP) and sympathetic skin responses (SSR).
  • - The findings suggest that pain habituation may remain intact in chronic pain patients, questioning its role as a reliable marker for central sensitization and highlighting the need for further research on pain mechanisms using advanced neurophysiological methods.

The birth of a premature infant and its subsequent hospitalization in the neonatal intensive care unit are stressful experiences for mothers. Because of uncertainty concerning interactions with a premature baby, mothers often feel helpless and only hesitantly assume their maternal role. This may have a negative impact on the mother-child interaction and prevents mothers from taking an active part in E46www.

We introduce an innovative, simple, effective segmentation-free approach for survival analysis of head and neck cancer (HNC) patients from PET/CT images. By harnessing deep learning-based feature extraction techniques and multi-angle maximum intensity projections (MA-MIPs) applied to Fluorodeoxyglucose Positron Emission Tomography (FDG-PET) images, our proposed method eliminates the need for manual segmentations of regions-of-interest (ROIs) such as primary tumors and involved lymph nodes. Instead, a state-of-the-art object detection model is trained utilizing the CT images to perform automatic cropping of the head and neck anatomical area, instead of only the lesions or involved lymph nodes on the PET volumes.

The standard of care approach to identify sentinel lymph nodes (SLNs) in clinically non-metastatic cutaneous melanoma patients is technetium (Tc)-based lymphoscintigraphy. This technique is associated with radiation exposure, a long intervention time, high costs, and limited availability. Indocyanine green (ICG)-based near-infrared fluorescence imaging offers a potential alternative if proven to be of comparable diagnostic accuracy.
