An Investigation of Sleep Macro‐ and Microarchitecture by APOE Genotype

Annals of Neurology, EarlyView.
Objectives Apolipoprotein E ε4 (APOE ε4), a robust genetic risk factor for Alzheimer's disease (AD) is associated with functional connectivity deficits and amyloid pathology in brain regions involved in sleep regulation. Thus, alterations in sleep architecture may be one pathway through which ε4 contributes to Alzheimer's disease vulnerability. However,

Pulse oximeter accuracy and precision at five different sensor locations in infants and children with cyanotic heart disease

Indian Journal of Anaesthesia, 2010
Since the invention of pulse oximetry by Takuo Aoyagi in the early 1970s, its use has expanded beyond the perioperative care into neonatal, paediatric and adult intensive care units (ICUs).

Safety and pharmacokinetics of mosliciguat, a new, inhaled soluble guanylate cyclase activator, in healthy adult subjects

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Mosliciguat (BAY 1237592), the first soluble guanylate cyclase (sGC) activator in a dry powder inhaler (DPI), could potentially treat pulmonary hypertension with a more targeted delivery than systemic sGC stimulators. We report safety and tolerability of mosliciguat in healthy men.

Utility of pulse-oximetry screening in newborns with nonductus-dependent cyanotic congenital heart defects: A reason to alarm?

Annals of Pediatric Cardiology, 2022
Objectives : We aimed to compare the performance of pulse-oximetry screening in detecting nonductus-dependent cyanotic congenital heart defects (CCHDs). Methods : In a prospective cross-sectional study, we recorded post ductal saturation of neonates (

Revisiting the concept that interictal implies asymptomatic: Pulse wave amplitude drops uncover autonomic responses during generalized paroxysmal fast activities

Epilepsia, EarlyView.
Abstract Objective Interictal electroencephalographic (EEG) activities are generally considered asymptomatic. Pulse wave amplitude drop (PWAD) is a marker of autonomic nervous system (ANS) reactivity linked to cardiovascular risk. Generalized paroxysmal fast activity (GPFA) is a major EEG pattern in different epileptic conditions.

Trendelenburg positioning with or without norepinephrine infusion for haemodynamic support in anaesthetised hypovolemic horses

Equine Veterinary Journal, EarlyView.
Abstract Background Intraoperative haemorrhage during equine anaesthesia is a rare but potentially fatal complication requiring prompt haemodynamic support. Postural manoeuvres such as Trendelenburg (TL) positioning and vasopressor support augment venous return and improve cardiac output (CO), yet their efficacy in anaesthetised hypovolemic horses ...

Diagnostic dilemma: Low oxygen saturation during cardiac surgery

Annals of Cardiac Anaesthesia, 2017
We report a case of rheumatic heart disease with severe mitral stenosis having cyanosis and low oxygen saturation on pulse oximetry. The findings of clinical examination and low values on pulse oximetry were inconsistent with the findings of normal ...

The accuracy of pulse oximetry in measuring oxygen saturation by levels of skin pigmentation: a systematic review and meta-analysis

BMC Medicine, 2022
Background During the COVID-19 pandemic, there have been concerns regarding potential bias in pulse oximetry measurements for people with high levels of skin pigmentation.

Dexmedetomidine infusions improve cardiovascular and renal function in anaesthetised, experimentally endotoxaemic horses

Equine Veterinary Journal, EarlyView.
Abstract Background Dexmedetomidine infusions are beneficial in anaesthetised endotoxaemic horses when administered concurrent to endotoxin, but post‐conditioning effects are unknown. Objectives To evaluate whether a dexmedetomidine infusion is beneficial in horses administered Escherichia coli O55:B5 lipopolysaccharides (LPS) endotoxin prior to ...
