Predicting Breath Hold Task Compliance From Head Motion.

Background: Cerebrovascular reactivity reflects changes in cerebral blood flow in response to an acute stimulus and is reflective of the brain's ability to match blood flow to demand. Functional MRI with a breath-hold task can be used to elicit this vasoactive response, but data validity hinges on subject compliance. Determining breath-hold compliance often requires external monitoring equipment.

Nutrients as epigenetic modulators in metabolic dysfunction-associated steatotic liver disease.

To improve understanding of the multifaceted nature of metabolic dysfunction-associated steatotic liver disease (MASLD), the American Association for the Study of Liver Diseases, in collaboration with the European Association for the Study of the Liver and the Latin American Association for the Study of the Liver, proposed a broader and more flexible definition, highlighting the role of underlying metabolic dysfunction. MASLD represents the most common chronic liver disease worldwide; however, the impact of the disease goes beyond its epidemiological aspects. Currently, the impact on patients and healthcare systems, due to hepatic and extrahepatic complications, is significant.

Vibration therapy during needle procedures improves pain sensitivity while worsening pain threshold: A randomized, crossover study of healthy volunteers.

Introduction: Despite advancements in pharmacological and non-pharmacological strategies, pain and anxiety during needle-related procedures affect most patients. Through activation of large diameter nerve fibers, vibration therapy has been proposed to alleviate pain by minimizing perception of concomitant painful stimuli. This study investigated the effectiveness of a Bluetooth-enabled haptic device (BHD) in reducing pain sensitivity and improving patient satisfaction during needle procedures.
