An Interchangeability Test Method for Developing IPG Impedance Equivalency Evidence for Cardiac Implantable Electronic Device Under MRI

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 883-891, August 2026.
ABSTRACT Purpose Patients with cardiac implantable electronic devices (CIEDs) may receive replacement device components over time, resulting in mixed‐manufacturer systems that pose unknown, potentially higher risk under MRI exposure. It is not clear how to efficiently evaluate whether adding a non‐original implantable pulse generator (IPG) changes the ...

A System for Retrofitting Conventional MRI Systems for Simultaneous Multinuclear MRI/MRS

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
We present a low‐cost system for retrofitting conventional narrow‐band MRI spectrometers with simultaneous multinuclear capability using heterodyne frequency translation. The system supports up to four nuclei and 16 receive channels, with reconfigurable transmit modes and inherent phase stability through a shared local oscillator architecture ...

Improved Radiofrequency Safety Modelling in MRI Using In Vivo Measurements of Brain Conductivity

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
A workflow for the comparison of simulated and measured B1+$$ {B}_1^{+} $$ maps was developed and applied to a study on human tissue (brain) electrical conductivity, investigating differences between conductivity values from ex vivo and in vivo measurements.

Task‐Evoked Functional Activation and Coupling With CSF Flow Detected in the Human Brain With Ultrashort Echo Time fMRI at 7 T

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
Ultrashort and zero echo time (UTE and ZTE) MRI techniques generate functional contrast through inflow effects, making them suitable for studying cerebral blood flow and cerebrospinal fluid (CSF) dynamics. In a 7‐T study of 13 participants performing a visual task, we demonstrate that UTE produced robust, reproducible activations with group‐level ...

Dexamethasone Versus Placebo in Comatose Survivors of Out‐of‐Hospital Cardiac Arrest: Study Protocol for a Multicenter Randomized Comparison Within the Danish Out‐of‐Hospital Cardiac Arrest Trial (DANOHCA)

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 7, August 2026.
ABSTRACT Background The inflammatory response to whole‐body ischemia, as seen in comatose survivors after out‐of‐hospital cardiac arrest (OHCA), is associated with increased morbidity and mortality. Early high‐dose dexamethasone may dampen the inflammatory response, which may diminish secondary brain damage and other organ injury and decrease mortality.

Prophylactic Olanzapine Versus Placebo in Comatose Survivors of Out‐of‐Hospital Cardiac Arrest: Protocol for a Multicenter Randomized Comparison Within the Danish Out‐of‐Hospital Cardiac Arrest (DANOHCA) Trial

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 7, August 2026.
ABSTRACT Background Delirium is a frequent complication in comatose Out‐of‐Hospital Cardiac Arrest (OHCA) survivors requiring postresuscitation intensive care and is associated with higher mortality and longer hospitalization. Despite this, there is no established pharmacologic strategy for delirium prevention in OHCA survivors.

Harvest increase and culling as tools for managing chronic wasting disease in white‐tailed deer

The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
We used an agent‐based model to simulate the effect of CWD management on a white‐tailed deer population in northwest Indiana and northeast Illinois. Our results suggest that wildlife managers should reconsider how and if they should manage CWD. Abstract Chronic wasting disease (CWD), a transmissible spongiform encephalopathy that affects white‐tailed ...
