Evolution of novel sensory organs in fish with legs.

How do animals evolve new traits? Sea robins are fish that possess specialized leg-like appendages used to "walk" along the sea floor. Here, we show that legs are bona fide sense organs that localize buried prey. Legs are covered in sensory papillae that receive dense innervation from touch-sensitive neurons, express non-canonical epithelial taste receptors, and mediate chemical sensitivity that drives predatory digging behavior.

Understanding Acceptability of Group Leisure Activities Used to Address Loneliness Among People Living With Dementia: An Exploratory Mixed-Methods Study.

This mixed-methods complementarity study explored family members', friends', and health care providers' perspectives of acceptability of group leisure activities as an intervention for loneliness experienced by older adults living with dementia. A sample of 25 family members, friends, and health care providers of people living with dementia in ON rated the acceptability of group leisure activities (adapted Treatment Perception and Preference questionnaire) and discussed their ratings in an interview. Quantitative (descriptive statistics) and qualitative (conventional content analysis) results were integrated to understand acceptability.

Nurses' decision-making related to administering as needed psychotropic medication to persons with dementia: an empty systematic review.

Behavioural and psychological symptoms of dementia occur in approximately 75% of people with dementia admitted to acute care. Acute care nurses' decision-making regarding administering 'as needed' (pro re nata or PRN) psychotropic medications to persons with dementia are not well understood. This is an important clinical concern because 'as needed' medications are given at the discretion of the nurse.

Exploring acute care nurses' decision-making in psychotropic PRN use in hospitalised people with dementia.

Aims And Objectives: To understand how acute care nurses make decisions about administering "as-needed" (PRN) psychotropic medications to hospitalised people with dementia (PWD).

Background: Behavioural and psychological symptoms of dementia occur in approximately 75% of PWD admitted to acute care. Despite this, few studies provide insight into the use and prevalence of psychotropic use in acute care.

Deconstructing Dissections: A Case Report and Review of Blunt Cerebrovascular Injury of the Neck.

Blunt cerebrovascular injury (BCVI) is a term encompassing traumatic carotid and vertebral artery dissection or disruption. While the reported incidence appears to be increasing as diagnostic modalities improve, these injuries are often diagnosed only after patients have developed acute neurologic symptoms. These injuries often result in severe permanent neurologic disability or death.

Golf-related injuries treated in United States emergency departments.

Objective: This study investigates unintentional non-fatal golf-related injuries in the US using a nationally representative database.

Methods: This study analyzed golf-related injuries treated in US hospital emergency departments from 1990 through 2011 using the National Electronic Injury Surveillance System database. Injury rates were calculated using golf participation data.
