Environmental and Molecular Mutagenesis, EarlyView.Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

Fluid-structure interaction simulations of venous valves: a monolithic ALE method for large structural displacements [PDF]
arXiv, 2018 Venous valves are bicuspidal valves that ensure that blood in veins only flows back to the heart. To prevent retrograde blood flow, the two intraluminal leaflets meet in the center of the vein and occlude the vessel. In fluid-structure interaction (FSI) simulations of venous valves, the large structural displacements may lead to mesh deteriorations and

Haematologica, 2019 We aimed to evaluate the performance of the Khorana score in predicting venous thromboembolic events in ambulatory cancer patients. Embase and MEDLINE were searched from January 2008 to June 2018 for studies which evaluated the Khorana score. Two authors

Prognostic Factors for Free Flap Failure in Head and Neck Reconstruction
Head &Neck, EarlyView.ABSTRACT Background The failure rate of free flaps varies from 0.8% to 10.6% in the literature in head and neck reconstruction. The primary objective was to identify prognostic factors for free flap failure. Methods We prospectively included all consecutive free flaps performed between August 2021 and January 2024, and used a multivariate Cox ...

Application of Biomaterials for the Prevention of Pharyngeal Fistulae: A Systematic Review
Head &Neck, EarlyView.ABSTRACT Background PharyngoCutaneous Fistulae (PCF) represent a significant clinical challenge in otorhinolaryngology practice. The use of biomaterials could improve outcomes or even replace the use of a flap in pharyngolaryngeal surgery. Methods This systematic review included all studies evaluating the application of biomaterials for the prevention ...

Non-contact hemodynamic imaging reveals the jugular venous pulse waveform [PDF]
arXiv, 2016 Cardiovascular monitoring is important to prevent diseases from progressing. The jugular venous pulse (JVP) waveform offers important clinical information about cardiac health, but is not routinely examined due to its invasive catheterisation procedure.

Immediate skin‐to‐skin contact and postpartum hemorrhagic morbidity
International Journal of Gynecology &Obstetrics, EarlyView.Abstract Objective To examine rates of postpartum hemorrhagic (PPH) morbidity among patients who did and did not have immediate skin‐to‐skin contact (SSC). Methods This study was a retrospective cohort of all non‐anomalous, term singleton vaginal births at a Level IV center over 2 years. Exclusion criteria included COVID‐19.

Paediatric pelvic fractures – an updated literature review
ANZ Journal of Surgery, Volume 92, Issue 12, Page 3182-3194, December 2022., 2022 Pelvic fractures in children secondary to trauma are rare and associated with multi‐system injuries. They differ from fractures in adults and therefore require different considerations in assessment and management. In our literature review, we reviewed the current evidence on the incidence, pathophysiology, assessment, management and complications of ...
