Animals can acquire new behavior through both individual and social learning. Several studies have investigated horses' ability to utilize inter-species (human demonstrator) social learning with conflicting results. In this study, we repeat a previous study, which found that horses had the ability to learn from observing humans performing an instrumental task, but we include a control for stimulus enhancement. One human demonstrator and thirty horses were included, and the horses were randomly assigned to one of three treatments: (A) full human demonstration, (B) partial human demonstration, and (C) no human demonstration. The task was for the horses to touch an object situated 1 m away from a feed box, to open this feed box, and thereby obtain a food reward. The success of each horse, the behavior directed towards the apparatus and the human, and behaviors indicative of frustration were observed. The results showed that horses observing a full and partial human demonstration were not more successful in solving the instrumental task than horses not observing any demonstration. Horses that did not solve the task expressed more box- and human-oriented behavior compared to successful horses, which may be an indication of motivation to solve the task and/or frustration from being unable to solve the task.

Use of Cemented Hemiarthroplasty for Femoral Neck Fractures.
J Am Acad Orthop Surg Glob Res Rev
January 2025
From the Department of Orthopaedics, University of Missouri-Kansas City, Kansas City, MO (Dr. Amin, Dr. Krumme, Dr. Gause, Dr. Dubin, and Dr. Cil), and the Department of Orthopaedics, Kansas City Orthopaedic Alliance, Leawood, KS (Dr. Krumme).
Geriatric femoral neck fractures are common orthopaedic injuries, which are associated with a high morbidity and mortality. Arthroplasty is the optimum treatment for many of these injuries, but debate exists regarding optimal surgical strategy. Multiple recent investigations have demonstrated strong superiority for cemented stems as compared with noncemented fixation with a decreased risk of periprosthetic fracture, shorter length of stay, lower cost, and decreased rate for revision surgery.

Background: The prevalence of hearing loss in infants in India varies between 4 and 5 per 1000. Objective-based otoacoustic emissions and auditory brainstem response have been used in high-income countries for establishing early hearing screening and intervention programs. Nevertheless, the use of objective screening tests in low- and middle-income countries (LMICs) such as India is not feasible.

Background: The escalating global scarcity of skilled health care professionals is a critical concern, further exacerbated by rising stress levels and clinician burnout rates. Artificial intelligence (AI) has surfaced as a potential resource to alleviate these challenges. Nevertheless, it is not taken for granted that AI will inevitably augment human performance, as ill-designed systems may inadvertently impose new burdens on health care workers, and implementation may be challenging.

Background: Physicians worldwide face the challenging task of improving patient satisfaction by reducing pain in injured patients. Currently, available therapeutic approaches provide only short-term relief of symptoms without addressing long-term satisfaction. This has led to exploring regenerative treatment options that can deliver better outcomes.

Exercising regularly promotes health, but these benefits are complicated by acute inflammation induced by exercise. A potential source of inflammation is cell-free DNA (cfDNA), yet the cellular origins, molecular causes, and immune system interactions of exercise-induced cfDNA are unclear. To study these, 10 healthy individuals were randomized to a 12-wk exercise program of either high-intensity tactical training (HITT) or traditional moderate-intensity training (TRAD).
