The Contrasting Role of Marine- and Land-Terminating Glaciers on Biogeochemical Cycles in Kongsfjorden, Svalbard.

This case study of Kongsfjorden, western coastal Svalbard, provides insights on how freshwater runoff from marine- and land-terminating glaciers influences the biogeochemical cycles and distribution patterns of carbon, nutrients, and trace elements in an Arctic fjord system. We collected samples from the water column at stations along the fjord axis and proglacial river catchments, and analyzed concentrations of dissolved trace elements, together with dissolved nutrients, as well as alkalinity and dissolved inorganic carbon. Statistical tools were applied to identify and quantify biogeochemical processes within the fjord that govern the constituent distributions.

Effectiveness comparison of genicular nerve ablation for knee osteoarthritic versus post-total knee arthroplasty pain.

Background: Genicular nerve radiofrequency ablation (GNRFA) is a popular and effective procedure to treat arthritic knee pain. For refractory arthritic pain that fails conservative treatment, total knee arthroplasty (TKA) has been an excellent option. Unfortunately, 15-30% of people who undergo a TKA continue to experience pain and stiffness in the knee.

Roles of collagen cross-links and osteon collagen/lamellar morphotypes in equine third metacarpals in tension and compression tests.

Many bones experience bending, placing one side in net compression and the other in net tension. Because bone mechanical properties are relatively reduced in tension compared with compression, adaptations are needed to reduce fracture risk. Several toughening mechanisms exist in bone, yet little is known of the influences of secondary osteon collagen/lamellar 'morphotypes' and potential interplay with intermolecular collagen cross-links (CCLs) in prevalent/predominant tension- and compression-loaded regions.

The buffet challenge: a behavioral assessment of eating behavior in adolescents with an eating disorder.

Objective: Eating disorders are characterized by disturbances in nutritional intake and abnormal mealtime behaviors. Laboratory eating paradigms offer a unique opportunity to accurately measure dietary intake and eating behaviors, however, these studies have predominantly occurred in adults. This paper describes the development and preliminary psychometric examination of the Buffet Challenge, a laboratory-based meal task for youths with an eating disorder.

Concurrent Pansinusitis and Orbital Cellulitis Complicated by Extensive Head and Neck Venous Thrombosis in an Unvaccinated Adolescent Patient with COVID-19: A Case Report.

Background: Orbital cellulitis is an infrequent but serious infectious complication of rhinosinusitis, most commonly seen in the pediatric population. Extension into the cavernous sinus, leading to further infection and thrombosis, is a rare but life-threatening complication. Although COVID-19 has been linked to an increased risk of venous thromboembolism, most cases involve extremity deep venous thrombosis or pulmonary embolism; reports of intracranial or jugular system thrombosis are rare.
