Anatomical Considerations for the Use of the Popliteal Vein as a Potential Alternative for Central Venous Cannulation

Anatomia
Limited reports have evaluated the utility of the popliteal vein (PV) specific to cannulation. The objective of this study was to characterize the diameter and length of the PV to evaluate this area as a potential cannulation site.

Multi‐site performance of the telemedicine retinopathy of prematurity severity score (tROP‐SS)

Acta Ophthalmologica, Volume 104, Issue 5, Page e590-e595, August 2026.
Abstract Objective This study aims to evaluate the performance of the telemedicine retinopathy of prematurity severity score (tROP‐SS) across all 14 NICUs in the TELEROP cohort against the modified ROP activity score (mROP‐ActS). Design Retrospective cohort study. Subjects The study included 2037 neonates who underwent ROP screening in 14 NICUs via the

Factors Associated with Recurrence of Varicose Veins after Thermal Ablation: Results of The Recurrent Veins after Thermal Ablation Study

The Scientific World Journal, 2014
Background. The goal of this retrospective cohort study (REVATA) was to determine the site, source, and contributory factors of varicose vein recurrence after radiofrequency (RF) and laser ablation. Methods. Seven centers enrolled patients into the study

Local Variability of Ice Core Ammonium and Black Carbon Records From Tunu and Summit, Greenland: Implications for Long‐Term Biomass Burning Reconstructions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Paleoclimate reconstructions of wildfire using ice cores often rely on high‐resolution aerosol records of refractory black carbon (rBC) or ammonium (NH4+). The interpretation of such records, however, can be hindered by uncertainties related to long‐range atmospheric transport, spatial distribution and strength of emissions, as well as ...

Design of driving assistance control for personal skid steer vehicle with model error compensator and its evaluation of outdoor driving

Nihon Kikai Gakkai ronbunshu, 2018
Recently, electrical welfare vehicles driven by two motors employing free casters are widely used by patients and elders. However, as the user is not able to drive the vehicle well on the uneven rough roads, it is necessary to apply a new mechanism to ...

Experimental validation of single-sided natural ventilation models on building simulation [PDF]

E3S Web of Conferences
In Europe, many office buildings rely on single-sided natural ventilation (SSV), which uses one or several openings on only one side of a room where the air exchange occurs primarily.

Influence of Subslab Aggregate Permeability on SSV Performance [PDF]

, 1991
The effectiveness of the technique of subslab ventilation (SSV) for limiting radon entry into basements was investigated through complementary experimentation and numerical modeling. Determination of the impact of subslab aggregate permeability on SSV performance was a primary objective.

Comment to: Pre-operative determination of anatomic variations of the small saphenous vein for varicose vein surgery by three-dimensional computed tomography venography, by Kim SY, Park EA, Shin YC, et al. Phlebology 2012;27:235-41.

Veins and Lymphatics, 2012
Short saphenous vein (SSV) surgery is more challenging due to higher recurrence and complication rates than great saphenous vein (GSV) surgery. The main reason for that is the presence of many anatomic variations in SSV anatomy and the close proximity of
