Osteosarcoma is almost identical in companion animals and in people, so research in basic cancer biology and treatment is readily translational across the species. In this article the authors (one DVM and one MD) present examples of species "cross talk" based on their parallel careers in musculoskeletal oncology surgery. Dogs in particular provide a relevant osteosarcoma model that is 10 times more prevalent than the corresponding human condition and offers a unique opportunity to answer questions related to local tumor control and metastasis. Advantages of the dog model include spontaneous development of the disease; the animal's large size, intact immune system, shared genetic aberrations, and response to traditional chemotherapies; and owners' acceptance and compliance with clinical trials for their pets. We describe several cross-species treatment strategies for osteosarcoma--chemotherapy, limb-sparing techniques, and radiation--as well as surprising impacts of infection and immunology. We conclude with some discussion of areas for further discovery and development to advance species cross talk in support of One Health.

Speech-Language Pathology Preservice Preparation for Working in School-Age Literacy: International Perspectives.
Lang Speech Hear Serv Sch
January 2025
School of Education, La Trobe University, Bendigo, Victoria, Australia.
Purpose: This narrative review of preservice training of speech-language pathologists (SLPs) to work in school-age literacy contexts examines (a) studies regarding SLPs' perceptions of their preservice training and (b) accreditation requirements for preservice training in selected nations.
Method: A review of the literature examining (a) SLPs' perspectives about their preservice training; (b) SLPs' beliefs, confidence, and self-efficacy; and (c) speech-language pathology preservice program content was conducted via analysis of studies published after the year 2010. Policy documents and websites outlining accreditation requirements in the United States, Canada, the United Kingdom, Australia, and New Zealand were reviewed.
Understanding Parental Perspectives on Childhood Hearing Impairment and Timely Interventions.
Cureus
January 2025
College of Medicine, Department of Otolaryngology - Head and Neck Surgery, University of Jeddah, Jeddah, SAU.
Objectives: Hearing impairment during childhood is a widespread health issue. Prompt recognition and timely intervention are vital for the advancement of language skills. Insufficient parental knowledge can lead to a delay in diagnosing and treating a condition, which can have a negative impact on academic performance.

Role of nasal microbiota in regulating host anti-influenza immunity in dogs.
Microbiome
January 2025
Joint International Research Laboratory of Animal Health and Food Safety, College of Veterinary Medicine, Nanjing Agricultural University, Nanjing, China.
Background: Numerous studies have confirmed a close relationship between the pathogenicity of influenza and respiratory microbiota, but the mechanistic basis for this is poorly defined. Also, the majority of these studies have been conducted on murine models, and it remains unclear how far these findings can be extrapolated from murine models to other animals. Considering that influenza A virus is increasingly recognized as an important canine respiratory pathogen, this study investigated the cross-talk between nasal and lung tissues mediated by microbes and its association with influenza susceptibility in a beagle dog model.

J Voice
January 2025
Universidade Estadual de Campinas - UNICAMP, Campinas, São Paulo, Brazil. Electronic address:
Objective: To analyze acoustic measures of speech and vowel samples from individuals of different genders and to correlate these acoustic measures with vocal satisfaction. This study aims to provide additional data on acoustic measures, serving as references for clinicians while emphasizing the importance of moving beyond cisgender norms. Additionally, it addresses a gap in the Brazilian context by exploring correlations between acoustic measures and self-perceived vocal satisfaction across diverse gender groups.
