Patient age affects sex-based differences in post-traumatic mortality: a national trauma registry study in Japan

Purpose Sex-based differences in post-traumatic mortality have been widely discussed for quite some time. We hypothesized that age-related pathophysiologic changes would affect sex-based differences in post-traumatic mortality and aimed to verify the hypothesis using a nationwide trauma registry in Japan. Methods This was a retrospective analysis of trauma patients registered in The Japanese Trauma Data Bank. We stratified the study population into the following three subsets based on age: (1) pediatric subset (age ≤ 14), (2) adult subset (age 15–50) and (3) senior adult subset (age ≥ 51). We evaluated both sex-based differences in mortality in each subset separately using multivariate logistic regression analysis and the two-way interaction effect for predicted survival between the continuous increase of age and the sexes using a nonlinear multivariate regression model. Results We included 122,819 trauma patients who fulfilled the inclusion criteria and classified them into the 3 subsets according to age. Male patients were more likely to die compared to female patients only in the senior adult subset (adjusted odds ratio: 1.26; 95% confidence interval: 1.18–1.36), whereas there were no statistically significant differences in the other two subsets. Furthermore, non-linear logistic regression analysis revealed that predicted survival probability in male patients decreased more sharply in accordance with the increase of age compared to that in female patients (p for interaction: 0.051). Conclusion Age-related change in post-traumatic mortality was significantly different between males and females, and male patients had a relatively higher risk of death in the older population.

Intergenerational music teaching and learning among preservice music teachers and senior adult musicians

The purpose of this study was to examine the intergenerational interactions between preservice music teachers and senior adult musicians engaged in music teaching and learning in a New Horizons ensemble within one university’s music teacher preparation program. This intrinsic qualitative case study included written reflections and observational data of 16 current undergraduate music education students and verbatim interview transcripts of 5 current and former students serving as teaching assistants who taught and conducted their university’s New Horizons ensemble. Findings distilled from the data included (a) how younger-aged preservice music teachers responded to generational differences while learning how to interact with senior adult musicians, (b) the pedagogical content knowledge (PCK) learned and developed by participants as a result of teaching in a New Horizons ensemble, and (c) the connections made by participants teaching senior adults to their future careers as professional music educators. Future discussion and directions from this study highlight emerging connections of research between adult and community music settings and music teacher education. Implications include (a) how to create best practices so that the missions and objectives of both music teacher education programs and cooperating community adult ensembles support and enhance each other, (b) fostering outcomes that prepare music education majors for experiences in adult music education, and (c) reimagining New Horizons and music teacher education partnerships that result in more national, racial, cultural, and musical diversity and inclusion.

Influence of Dietary Ingredients on Lean Body Percent, Uremic Toxin Concentrations, and Kidney Function in Senior-Adult Cats

The goal of this study was to determine if modification of currently available maintenance foods with alternative ingredients, botanicals (fruit and vegetables), and increased amounts of functional lipids (fish oil) would delay the age-associated decline in glomerular filtration rate (GFR) and lean body mass (LBM) in senior-adult cats. Forty-four healthy cats (mean age, 12.2 years; range 10.7 to 14.0 years) were fed one of three foods (n = 14 or 15 per group) for six months: control food with 32.6% protein (as fed), or control food supplemented with increasing amounts of functional food bioactives: fish oil, fruit and vegetables, different protein sources, and <32.0% protein [functional foods one (FF1) and two (FF2)]. Senior-adult cats were compared before and after the feeding trial with 20 young-adult cats (mean age, 3.5 years; range 2.1 to 4.9 years). Compared with younger cats, older cats had decreased lean-body percent and serum albumin concentrations. Feeding FF1 and FF2 for six months increased lean-body percent, maintained serum albumin concentrations, increased GFR, decreased serum symmetric dimethylarginine (SDMA) concentrations, and decreased concentrations of the uremic toxin 3-indoxyl sulfate. These dietary changes may assist in offsetting sarcopenia and the chronic inflammation associated with aging in senior-adult cats.

LIFELONG LANGUAGE LEARNING IN EUROPE: POSSIBILITIES AND CHALLENGES

Recent demographic changes in Europe (ageing, migration and others) demonstrate the importance of senior adult education – an urgent issue at both national and European Union policy levels. The problem of the research is grounded in the challenges that many European societies currently face: the retirement age being extended, employees need to adapt to the changed working conditions and satisfy urgent demands of the market. The aim of this research is to examine the current situation of senior adult language education in the EU. The research objectives question one of the basic needs faced by senior citizens - to acquire or maintain multilingual skills, without which their status in the competitive market would become complicated. In many European countries, senior adult education is viewed as an integral part of the whole education system that is directed towards engagement of senior citizens into active social life, job maintenance, development of cross-cultural communicative and language skills and more diverse opportunities for self-realization.
