- Patient safety culture: radiographers’ perceptionPublication . Ribeiro, Luís Pedro; Ribeiro, A.M.; Azevedo, Kevin; Abrantes, António; Lesyuk, Oksana; Almeida, Rui; Fernandes, Sara; da Silva, Carlos; Rodrigues, SóniaResearch to evaluate radiographers’ perceptions about patient safety culture in Portuguese public and private imaging facilities found that overall perception is positive but the safety culture dimensions rating should guide culture development of safety culture improvement action plans.
- Bone density and fall risk screening in Algarve: A preliminary studyPublication . Ribeiro, Luís Pedro; Pinheiro, João; Abrantes, António; Ribeiro, A.M.; Vicente, Bianca I. C.; Almeida, Rui; Gonçalves, Tânia; Ferreira, M. A. G. A.; Farinha, Maria Conceição; Azevedo, KevinOsteoporosis is a major cause of morbidity and mortality around the world and is a silent disease characterized by low bone strength that results in an increased risk of fracture. The benefits of being physically active in advanced ages to reduce the loss of bone mineral density (BMD) and improve functional capacities are well known. Quantitative ultrasound (QUS) is a peripheral bone densitometry technique that is rapidly gaining in popularity for the assessment of skeletal status, along with fall risk assessment. This chapter consists of a brief review of the literature on osteoporosis and describes ongoing activities on bone density and fall risk prevention in Algarve, Portugal as part of EIP AHA´s action group on fall prevention with the presentation of a preliminary study. This study aimed to demonstrate that the postmenopausal female seniors who adhere to the recommendations for the regular program of physical activity after osteoporosis screening one year later show a slower decrease in BMD.
- Interpretation of many-valuedness in quality-of-life instrumentsPublication . Ribeiro, Luís Pedro; Eklund, Patrik; Gomes Alves Ferreira, Maria Augusta; Magalhães Ribeiro, Anabela de; Farinha, Maria Conceição; Paiva, Maria Adelaide; Gonçalves, Tânia; de Almeida Fontes, Ana Paula; Pinheiro, JoãoAssessment instruments for functioning in general and quality of life in particular often involve discrete scales with three, four, or five values, or Visual Analogue Scales (VAS) with a range 0–100. VAS scales often need to be downsized and discretized using intervals or clusters. Cutoff points for these intervals/clusters need to be carefully selected and justified. Our objective was to underline the importance of providing clear interpretations of many-valuedness appearing in quality-of-life (QoL) instruments, and to present a methodology for the provision of such clearness. Doing so, we view QoL scales as originating within the World Health Organization (WHO).
- Skeletal maturity in adolescence: evaluating bone development and age metricsPublication . Pinheiro, João; Ribeiro, Luís; Teixeira, Diana; Magalhães Ribeiro, Anabela de; Coelho-e-Silva, Manuel JoãoBackground/Objectives: Bone maturation and development are crucial for growth and development, especially in children and adolescents; however, some qualitative methods, such as Greulich & Pyle, do not provide accurate data. Our aim is to verify whether skeletal age (SA) can predict and correlate with bone mineral content (BMC), bone mineral density (BMD), and body composition (BC). Methods: A cross-sectional study was conducted on 115 male adolescents (ages 12.1-15.8 years). Skeletal age was assessed using the Tanner-Whitehouse 3 (TW3) method, while BMC, BMD, and BC were measured using full-body DXA. Anthropometric data, including height and body mass, were also recorded. Statistical analysis included descriptive methods and bivariate correlation coefficients. Results: SA was significantly correlated with stature (r = 0.598, p = 0.001) and body mass (r = 0.517, p = 0.001), showing a stronger association than chronological age (CA) for these variables. Body composition variables, including lean mass (LM) (r = 0.521, p = 0.001) and fat tissue (FT) (r = 0.522, p = 0.001), also showed a stronger correlation with SA than CA. However, associations between SA and bone parameters were weaker: BMC (r = 0.103, p = 0.275) and BMD (r = 0.161, p = 0.086) did not reach statistical significance. When stratified by SA/CA tertiles, individuals in the highest tertile exhibited slightly greater BMC (1439 +/- 108.32 g) and BMD (1.028 +/- 0.127 g/cm2), though without a significant effect. These findings suggest a dynamic but complex relationship between skeletal age and bone development. Conclusions: SA demonstrates a stronger association with anthropometric and body composition variables than CA, highlighting its potential as a predictor of growth used in conjunction with LM and FM. However, its relationship with BMD and BMC remains inconclusive, warranting further longitudinal research, considering limitations regarding nutritional intake.
