A Functional Response in Resource Selection Links Multiscale Responses of a Large Carnivore to Human Mortality Risk.

Theory suggests that animals make hierarchical, multiscale resource selection decisions to address the hierarchy of factors limiting their fitness. Ecologists have developed tools to link population-level resource selection across scales; yet, theoretical expectations about the relationship between coarse- and fine-scale selection decisions at the individual level remain elusive despite their importance to fitness. With GPS-telemetry data collected across California, USA, we evaluated resource selection of mountain lions (Puma concolor; n = 244) relative to spatial variation in human-caused mortality risk.

Outcomes after per oral pyloromyotomy based on gastroparesis etiology.

Background: Per oral pyloromyotomy (POP) has been shown to be effective in patients with gastroparesis. The three most common etiologies of gastroparesis are diabetic, postsurgical, and idiopathic. Our aim was to compare outcomes after POP based on the etiology of gastroparesis.

Intrinsic and environmental drivers of pairwise cohesion in wild Canis social groups.

Animals within social groups respond to costs and benefits of sociality by adjusting the proportion of time they spend in close proximity to other individuals in the group (cohesion). Variation in cohesion between individuals, in turn, shapes important group-level processes such as subgroup formation and fission-fusion dynamics. Although critical to animal sociality, a comprehensive understanding of the factors influencing cohesion remains a gap in our knowledge of cooperative behavior in animals.

Evaluation of Vestibular Schwannoma Size Over Time: How Well do the Experts Perform and What can be Improved?

Background And Purpose: 2D linear measurements are often used in routine clinical practice during vestibular schwannoma (VS) follow-up, primarily due to wider availability and ease of use. We sought to determine radiologist performance compared to 3D-volumetry, along with the impact of number of linear measurements, slice thickness and tumor volumes on these parameters.

Materials And Methods: Single center retrospective study with 97 patients (592 MRI studies).

Torus palatinus osteonecrosis: A hitherto unreported complication of long-term Denosumab use.

Torus palatinus is an osseus exostosis found in the midline of the hard palate. It is a relatively common condition and is benign in nearly all cases. However, complications such as airway obstruction, sleep apnea, and swallowing difficulties do exist.
