Flexible wearable electronics for cardiovascular monitoring from surface signals to deep physiological insights

FlexMat, EarlyView.
This review organizes flexible wearable electronics for cardiovascular monitoring into four interconnected information layers: surface electrophysiology, hemodynamic sensing, vascular imaging, and biofluid biomarker analysis. This framework clarifies how electrical rhythm, vascular loading, structural and flow‐related features, and biochemical states ...

Ultrafast fMRI Detects Age‐Related Changes in Harmonics of Cardiac Pulsations in the Brain at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Aging impacts pulsatility of blood vessels in the brain, reflecting vascular health. Resolving characteristics of cardiac pulsatility requires faster acquisitions than traditional fMRI. An ultrafast fMRI method was developed and applied to sample several harmonics of cardiac pulsations at 7 T.

Accuracy and precision of continuous, non‐invasive blood pressure devices: a systematic review and meta‐analyses

Anaesthesia, EarlyView.
Summary Introduction Reliable continuous non‐invasive blood pressure monitoring technology should support clinicians to maintain blood pressure within appropriate limits peri‐operatively. Previous studies have shown conflicting results regarding measurement accuracy.

Retinal oxygen saturation and retinal vessel diameter in glaucoma patients before and after trabeculectomy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To compare retinal vessel oxygen saturations and diameters before, 1 and 3 months after trabeculectomy. Methods Retinal oxygen saturations and vessel diameters were obtained using retinal oximetry. The effect of the postoperative intraocular pressure (IOP) decrease on the arteriovenous difference (AV‐difference) was evaluated ...

Interpreting the structure–function relationship in high myopia‐associated glaucoma: A review

Acta Ophthalmologica, EarlyView.
Abstract Visual field (VF) interpretation in high myopia‐associated glaucoma (HMG) is challenging due to frequent structure–function discordance and coexisting myopia‐related changes. These changes may reduce the reliability of conventional structure–function mapping and increase the risk of misclassifying non‐glaucomatous VF abnormalities as ...

Real‐world insights on switching aflibercept dosage for enhanced outcomes in age‐related macular degeneration (RISE‐AMD): Safety data

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate real‐world safety experience with aflibercept 8 mg in a large case series of patients with neovascular age‐related macular degeneration (nAMD). Methods Due to a high proportion of patients on short treatment intervals, patients with nAMD at a Danish tertiary retina clinic were systematically switched to aflibercept 8 mg ...

Variation in measuring and ophthalmic factors correlating with central corneal thickness in the Northern Finland birth cohort eye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose To assess the correlation between optical coherence tomography (OCT) and ultrasound pachymetry (USP) as methods for analysing central corneal thickness (CCT) and to evaluate ophthalmic factors affecting CCT. Methods The eyes of 3070 subjects of the Northern Finland Birth Cohort (NFBC) were examined at the age of 45–49 years.

Equine eyelid reconstruction by semi‐circular skin flap blepharoplasty

Equine Veterinary Education, EarlyView.
Summary Reconstructive surgeries of the equine eyelid carry significant challenges for the equine surgeon, due to the poorly mobile and tightly adhered facial skin in this species. Preservation of lid function is an essential surgical consideration in order to maintain protection of the globe and cornea and to provide ocular comfort to the case ...

Reduced order modelling of air‐puff test for corneal material characterisation

Journal of Microscopy, EarlyView.
Abstract Models of the fluid–structure interaction (FSI) model for the air‐puff test were analysed. Using Abaqus, the air‐puff test is applied to eyes with varying biomechanical parameters, such as material properties, corneal thickness, and radius.

Ocular Pharmacokinetics of Topical Chloramphenicol in Dogs: Effects of Concentration and Vehicle Formulation

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT This study compared tear film exposure and retention of four chloramphenicol ophthalmic formulations in dogs, evaluating the effects of drug concentration (0.2% to 5%) and vehicle type (solution vs. ointment). Eight healthy dogs were enrolled in a randomized paired‐eye crossover study consisting of two sessions with a 7‐day washout.
