The association of hypotension during non‐cardiac surgery, before and after skin incision, with postoperative acute kidney injury: a retrospective cohort analysis

Anaesthesia, 2018
Intra‐operative hypotension is associated with acute postoperative kidney injury. It is unclear how much hypotension occurs before skin incision compared with after, or whether hypotension in these two periods is similarly associated with postoperative ...

Cortical Microvascular Pulsatility in the Aging Mouse Brain and the Confounding Effects of Anesthesia

Advanced Science, EarlyView.
Multi‐modal optical imaging reveals microvascular pulsatility in the brain cortex of awake and anaesthetized mice. Awake hemodynamics in male mice are found to be remarkably stable until late life, with flow pulsatility being significantly higher than in females, despite similar average perfusion.

Unexpectedly High Incidence of Immune‐Related Adverse Events in Gastric Cancer Patients Who Received Conversion Surgery After Nivolumab‐Including Chemotherapy

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Nivolumab‐including chemotherapy (nivo‐CTX) for stage IV gastric cancer (GC) may increase the chance of conversion surgery but risk of immune‐related adverse events (irAEs) during perioperative period remains unclear. Methods We examined irAEs in 36 patients with marginally resectable GC who received nivo‐CTX followed by surgery ...

Intradialytic Hypotension: Mechanisms and Outcome

Blood Purification, 2019
Intradialytic hypotension (IDH) occurs in approximately 10–12% of treatments. Whereas several definitions for IDH are available, a nadir systolic blood pressure carries the strongest relation with outcome.

Wearable Metamaterials with Embodied Intelligence for Programmable Control of Human Limbs Tremor

Advanced Intelligent Systems, EarlyView.
Resulting from alternating muscle contractions, tremors can severely limit human ability to perform everyday tasks like walking or talking, due to their disruptive nature. Medication and surgery may not always effectively address tremor control. A wearable device embodying programmable smart metamaterials with adaptable intelligence to meet the demand ...

Modulation of Neurally Mediated Vasodepression and Bradycardia by Electroacupuncture through Opioids in Nucleus Tractus Solitarius. [PDF]

, 2018
Stimulation of vagal afferent endings with intravenous phenylbiguanide (PBG) causes both bradycardia and vasodepression, simulating neurally mediated syncope.

Association Between Perioperative Hypotension and Delirium in Postoperative Critically Ill Patients: A Retrospective Cohort Analysis

Anesthesia and Analgesia, 2019
BACKGROUND: Postoperative delirium is common in critically ill patients, with a reported incidence of 11%–43%, and is associated with significant morbidity and cost. Perioperative hypotension and consequent brain hypoperfusion may contribute.

Disease Progression in Multiple System Atrophy: The ASPIRE Multi‐Modal Biomarker Study

Annals of Neurology, EarlyView.
Objective The objective of this study was to characterize changes in candidate biomarkers in early multiple system atrophy (MSA) and identify baseline predictors of faster progression. Methods This 1‐year, multicenter, prospective study assessed clinical, neuroimaging (3T‐magnetic resonance imaging [MRI], dopamine transporter single‐photon emission ...

Investigation of in vivo measurement of cerebral cytochrome-c-oxidase redox changes using near-infrared spectroscopy in patients with orthostatic hypotension [PDF]

, 2007
We have previously used a continuous four wavelength near infrared spectrometer to measure changes in the cerebral concentrations of oxy- (Δ[HbO2] and deoxy- haemoglobin (Δ[HHb]) during head-up tilt in patients with primary autonomic failure.
