Placental Abruption and Perinatal Mortality: Abnormal Placentation and Spontaneous Abortion as Contributors to Left Truncation Bias

Paediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Generally, studies in perinatal epidemiology restrict cohort entry to 20 weeks of gestation, but exposures and outcomes may occur earlier. This restriction may introduce left truncation bias. Objectives To examine the impact of left truncation bias when estimating the causal effect of abruption on perinatal mortality in the context ...

The Invisible Burden: Examining the Impact of Exposure Misclassification in Epidemiologic Analyses of Uterine Fibroids

Paediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Uterine fibroids, a common gynaecologic condition, are often underdiagnosed, potentially biasing results in epidemiologic studies due to measurement error. Objectives To examine how varying sensitivity in detecting uterine fibroids impacts effect estimates, using the association with hypertension onset as an example.

Bilateral simultaneous cataract surgery and intraocular lens implantation in an adult female chimpanzee (Pan troglodytes) inducing monovision

Veterinary Ophthalmology, Volume 28, Issue 2, Page 457-464, March 2025.
Abstract Background Cataract is the major cause of visual impairment in humans. Phacoemulsification with intraocular lens (IOL) implantation is the standard technique for cataract treatment with a high success rate. In a few cases, the surgical cataract procedure and lens implantation have been applied in non‐human primates.

Resistance exercise breaks during prolonged sitting augment the blood flow response to a subsequent oral glucose load in sedentary adults

Experimental Physiology, EarlyView.
Abstract Sitting‐induced impairments in postprandial blood flow are an important link between sedentary behaviour and cardiometabolic disease risk. The objective of this work was to examine the effects of resistance exercise breaks (REB) performed every 30 min during an otherwise sedentary 3‐h period on the vasodilatory response to a subsequent oral ...

The search for the ultimate exercise countermeasure to preserve crew health and ensure mission success in long‐duration spaceflight

Experimental Physiology, EarlyView.
Abstract The current understanding of crew health maintenance is founded upon decades of physiological research conducted in terrestrial spaceflight analogues and in low Earth orbit, particularly on the International Space Station. However, as we progress towards the Lunar Gateway and interplanetary missions, it is imperative that the tools employed to

Passive hyperthermia increases blood circulation in specific regions, largely independent of conduit artery mechanics and cardiac performance

Experimental Physiology, EarlyView.
Abstract Passive hyperthermia increases net peripheral and systemic blood flow in humans and other animals, yet the underlying haemodynamic forces that selectively accelerate blood movement remain incompletely characterized. Wave intensity analysis offers insight into the respective contributions of the heart and the vascular system to changes in blood
