Assessing response to stressful emotions: a controlled crossover study using pupillometry.
Porto Biomed J
January 2025
Basic and Clinical Immunology Unit, Department of Pathology, Faculty of Medicine, University of Porto, Porto, Portugal.
Background: Fear and horror induce autonomic protective responses, acting as "survival intelligence." Pupillometry is an innovative method that captures real-time autonomic nervous system reactions to stress.
Objective: To evaluate the feasibility of pupillometry to assess the acute response to a passive real-life stressor-viewing a truthful war scene.
A rare case of lipomatous ganglioneuroma of the adrenal gland.
Urol Case Rep
March 2025
Department of Urology, Liverpool Hospital, Liverpool, NSW, Australia.
Lipomatous ganglioneuroma's are exceedingly rare benign tumours. They originate from the neuroepithelium along the sympathetic ganglia. These rare tumours have been reported generally in the posterior mediastinum and retroperitoneum.

January 2025
Department of Oncology, Shanghai East Hospital, School of Medicine, Tongji University, Shanghai, 200092, P.R. China.
Background: The colon and rectum are highly innervated, with neural components within the tumor microenvironment playing a significant role in colorectal cancer (CRC) progression. While perineural invasion (PNI) is associated with poor prognosis in CRC, the impact of nerve density and diameter on tumor behavior remains unclear. This study aims to evaluate the prognostic value of nerve characteristics in CRC and to verify the impact of nerves on tumor growth.

Cancer Metastasis Rev
January 2025
Cancer Early Detection Advanced Research Center (CEDAR), Knight Cancer Institute, Oregon Health and Science University, Portland, OR, USA.
Nerve signaling within the tumor microenvironment (TME) plays a critical role in the initiation, progression, and metastasis of solid tumors. Due to their highly responsive behavior and activation upon injury and cancer onset, this review specifically focuses on how sympathetic nerves rewire the TME. Within tumors, sympathetic nerves closely interact with various TME components, and their combined signaling often shifts tumor-intrinsic physiology toward tumor-supportive phenotypes.

Enferm Intensiva (Engl Ed)
January 2025
Grupo de Trabajo de Analgesia, Sedación, Contenciones y Delirio de la Sociedad Española de Enfermería Intensiva y Unidades Coronarias (GT-ASCyD-SEEIUC), Spain; Área del paciente crítico, Reanimación y Anestesia, Hospital Universitario de Girona Dr. Josep Trueta, Girona, Spain; Departamento de Enfermería, Universitat de Girona (UdG), Girona, Spain.
Electrophysiological monitoring of pain provides objective measures that allow for pain control and adjustment of analgesia in non-communicative patients. Among the available electrophysiological devices, automated infrared pupillometry, Analgesia Nociception Index (ANI), and Nociception Level Index (NOL®) stand out. These non-invasive measurement systems analyze the sympathetic or parasympathetic nervous system response to painful stimuli by observing pupillary dilatation and reactivity (pupillometry), heart rate during respiration (ANI), or a combination of multiple parameters from the nociceptive-autonomic medullary circuit (NOL®).
