Swelling assessment after total knee arthroplasty.

Background: Total knee arthroplasty is a commonly performed elective orthopaedic surgery. Patients may endure substantial knee swelling following surgery, which are attributable to both effusion and edema. Studies have been aiming to identify an accurate and reliable method to quantify post-operative knee swelling to aid monitoring progress and treatment.

Retained anterior chamber graphite foreign body with delayed inflammation.

Purpose: To report a case of retained anterior chamber graphite foreign body with subsequent inflammation 20 years later.

Observations: A 29-year-old female who presented with first episode of acute blurring of vision and eye redness was noted to have a retained intraocular graphite foreign body in her anterior chamber. She recalled being accidently hit by a mechanical pencil 20 years ago.

Flower Strips in Wheat Intercropping System: Effect on Pollinator Abundance and Diversity in Belgium.

The decline of pollinators in agricultural areas has been observed for some decades, this being partly due to landscape simplification in intensive agrosystems. Diversifying agricultural landscapes by sowing flower strips within fields could reduce these adverse effects on biodiversity. In this context, the study presented here aimed at assessing and comparing the abundance and diversity of bees (Hymenoptera: Anthophila) and hoverflies (Diptera: Syrphidae) found and visiting flowers in three types of flower strips in Belgium: (i) a mixture of 11 wild flowers, (ii) a monofloral strip of (Asteraceae) and (iii) a monofloral strip of (Brassicaceae), where the last two are considered to be intercrops since they are valuable on the market, all sown within a field of winter wheat ( L.

How Patient Partners Influence Quality Improvement Efforts.

Background: There is growing acknowledgement that patients are key stakeholders in improving quality of medical care, yet a key barrier to integrating patients into quality improvement teams (QITs) as patient partners is the lack of evidence of their impact. This mixed-method study was conducted to identify the ways patient partners influence QITs and to document the extent of patient partners' impact.

Methods: Focus groups and in-depth interviews were conducted with 17 patient partners and 11 staff at WellSpan Health and Aligning Forces for Quality-South Central Pennsylvania to identify the specific mechanisms through which patients influenced QIT efforts.

Pumping liquid metal at high temperatures up to 1,673 kelvin.

Heat is fundamental to power generation and many industrial processes, and is most useful at high temperatures because it can be converted more efficiently to other types of energy. However, efficient transportation, storage and conversion of heat at extreme temperatures (more than about 1,300 kelvin) is impractical for many applications. Liquid metals can be very effective media for transferring heat at high temperatures, but liquid-metal pumping has been limited by the corrosion of metal infrastructures.
