Sustained Tear Film Exposure After Parenteral Cefovecin Administration in Dogs: Pharmacokinetics and Relevance to Canine Bacterial Keratitis

Veterinary Ophthalmology, Volume 29, Issue 5, September 2026.
ABSTRACT Objective To characterize the tear film pharmacokinetics of parenterally administered cefovecin (Convenia) and compare tear concentrations with the minimum inhibitory concentrations (MICs) of common ocular pathogens. Animals Studied Six healthy research‐bred Beagles.

The Role of Trace Elements in the Formation of Feline Corneal Sequestra

Veterinary Ophthalmology, Volume 29, Issue 5, September 2026.
ABSTRACT Objective To characterize the trace element composition of feline corneal sequestra (FCS) and provide insights into their pathophysiology. Methods FCS samples were collected from 11 eyes of 9 cats following keratectomy and compared with corneal samples from four clinically normal control cats euthanized for reasons unrelated to the study ...

Obstructive Sleep Apnea: Epidemiology, Pathophysiology, Complications, Diagnosis, Management, and Emerging Fibrosis‐Linked Remodeling

MedComm, Volume 7, Issue 8, August 2026.
Obstructive sleep apnea (OSA) is characterized by recurrent upper‐airway collapse, which generates key nocturnal stressors including intermittent hypoxia, sleep fragmentation, intrathoracic pressure stress, and sympathetic activation. These physiological disturbances converge on shared biological mechanisms, including oxidative stress, inflammation ...

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

Acta Ophthalmologica, Volume 104, Issue 5, Page 544-550, August 2026.
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 ...

Ventricular‐vascular coupling at rest and immediately following maximal exercise in adults with and without multiple sclerosis

Physiological Reports, Volume 14, Issue 15, August 2026.
Abstract Multiple sclerosis (MS) may impair ventricular‐vascular coupling (VVC), a measure of the interaction between the cardiac and vascular systems. We evaluated if VVC differed between individuals with and without MS with similar age‐predicted fitness.

Hepatosplanchnic perfusion changes following isolated abdominal trauma and surgery: A scoping review of evidence dominated by pneumoperitoneum models

Physiological Reports, Volume 14, Issue 15, August 2026.
Abstract The hepatosplanchnic vascular response to isolated abdominal organ injury remains poorly defined. The aim of this review was to synthesize the available evidence on macrovascular hepatosplanchnic flow and organ‐specific microvascular perfusion following isolated abdominal injury or surgery.
