Background: Ageism is one of the common forms of discrimination and prejudice. It has also been shown to be present in health professionals, including doctors, nurses, and medical students., Aims: The aim of this study was to translate the Ageism Scale For Dental Students (ASDS) into Polish, perform a culture adaptation, and conduct a preliminary validation analysis., Methods: The survey was administered to 202 third-, fourth-, and fifth-year students at the Jagiellonian University (No. 1072.6120.283.2020). Data were analyzed using principal components analysis (PCA) with an oblique, Promax rotation, and confirmatory factor analysis (CFA). Cronbach's alpha (α) was calculated to check the internal consistency reliability. Discriminant validity was analyzed using the Mann-Whitney and Kruskal-Wallis test., Results: PCA produced a 10-item scale distributed into three factors, which explains 59.52% of the total variance. Factor 1 ("preconceived notions about dental treatment") contained four items (α = 0.703), Factor 2 ("cost-benefit of providing care for older patients")-four items (α = 0.660) and Factor 3 ("dentist-older patient interaction")-two items (α = 0.662). CFA confirmed that the model is a good fit (RMSE = 0.058, 90% CI from 0.014 to 0.092, CFI = 0.950, and TLI = 0.926). The discriminant validity showed statistically significant differences in factors or individual items related to the year of the study, gender, and having a history of living with an older person(s) or an older patient(s) treated., Conclusion: The validation of the ASDS conducted in Poland identified 10 items with sufficient validity and reliability., (© 2024 The Author(s).

Material development in acoustic engineering plays a significant role in various applications, such as industrial noise control. It is important and relevant to consider alternative materials capable of reducing noise levels in different frequency ranges. One commonly used material in engineering structures is epoxy adhesive compositions. Favoring the use of adhesive compositions are their main characteristics, including weight reduction in structures, corrosion resistance, relatively low manufacturing costs, and high mechanical strength. This paper aims to discuss the relationship between the mechanical properties of modified epoxy adhesives, their structure, and sound absorption efficiency. The subjects of this study were specimens of an epoxy composition in the cured state. Acoustic absorption coefficients were evaluated using a dual-microphone impedance tube, and tensile, compressive, and bending strength properties were determined using a testing machine. The impact strength of the compositions was also investigated. An analysis of the structure of the adhesives in the cured state was carried out using a scanning electron microscope. The test specimens were made from Epidian 5 epoxy resin cured with a polyamide PAC curing agent. Nanobent ZR2 aluminosilicate in an amount of 1%, CaCO 3 calcium carbonate in an amount of 5%, and CWZ-22 activated carbon in an amount of 20% were used as modifiers. The conducted studies revealed that the highest tensile strength was obtained for the adhesive composition with the addition of ZR2 filler. The highest compressive strength was exhibited by the adhesive composition with the addition of CWZ-22 filler. The highest flexural strength was demonstrated by the unmodified composition. For all the tested adhesive compositions, low sound absorption values were achieved, with a maximum of approximately 0.18. From the perspective of the reduction index R , it was observed that these samples performed better in reduction than in absorption. The best values were achieved in the compositions modified with CaCO 3 .

This research presents an original method for synthesizing styrylfurans using N-heterocyclic carbenes (NHCs) and Brønsted acid catalysis. By exploiting 2,4-dioxoesters as conjugated 1,3-dicarbonyls, we have developed a technique allowing the efficient formation of highly functionalized styrylfurans with interesting photochemical properties, through a NHC-catalyzed cross-benzoin reaction followed by a Brønsted acid-driven Paal-Knorr-like condensation. This approach permits the integration of various substituents on the furan ring, with preliminary biological studies indicating potential as fluorescent dyes.

A new and unprecedented stereoselective synthetic approach to δ-oxoesters derivatives from readily available starting materials has been developed. This method, catalyzed by N-heterocyclic carbene, involves an annulation-deoxalation reaction of alkynyl aldehydes with 2,4-diketoesters and proceeds via the chiral α,β-unsaturated acylazolium intermediates. The annulation includes the in situ formation of dihydropyranones, which undergo ring-opening methanolysis with Lewis acid activation, followed by deoxalation to afford chiral 1,5-ketoesters in moderate to good yields.

Purpose: Non-pharmacological interventions (NPIs) play an important role in the management of older people receiving homecare. However, little is known about how often specific NPIs are being used and to what extent usage varies between countries. The aim of the current study was to investigate the prevalence of NPIs in older homecare recipients in six European countries., Methods: This is a cross-sectional study of older homecare recipients (65+) using baseline data from the longitudinal cohort study 'Identifying best practices for care-dependent elderly by Benchmarking Costs and outcomes of community care' (IBenC). The analyzed NPIs are based on the interRAI Home Care instrument, a comprehensive geriatric assessment instrument. The prevalence of 24 NPIs was analyzed in Belgium, Germany, Finland, Iceland, Italy and the Netherlands. NPIs from seven groups were considered: psychosocial interventions, physical activity, regular care interventions, special therapies, preventive measures, special aids and environmental interventions., Results: A total of 2884 homecare recipients were included. The mean age at baseline was 82.9 years and of all participants, 66.9% were female. The intervention with the highest prevalence in the study sample was 'emergency assistance available' (74%). Two other highly prevalent interventions were 'physical activity' (69%) and 'home nurse' (62%). Large differences between countries in the use of NPIs were observed and included, for example, 'going outside' (range 7-82%), 'home health aids' (range 12-93%), and 'physician visit' (range 24-94%)., Conclusions: The use of NPIs varied considerably between homecare users in different European countries. It is important to better understand the barriers and facilitators of use of these potentially beneficial interventions in order to design successful uptake strategies., (© 2023. The Author(s).)

Aims: To assess the prevalence of burnout and associated factors among healthcare workers (HCWs) working in a hospital admitting patients with COVID-19., Background: Burnout among HCWs is related to age, gender and occupation. However, little is known about organisational factors associated with burnout during the COVID-19 pandemic., Design: A cross-sectional study of 1412 hospital HCWs (748 nurses) was carried out via online survey during the COVID-19 pandemic between 4 and 19 January 2021., Methods: The Maslach Burnout Inventory-Human Services Survey, the Checklist Individual Strength questionnaire, the interRAI items covering mental health, the WHO questionnaire items assessing HCWs' preparedness and exposure to SARS-CoV-2 were used. Univariable and multivariable linear regression analyses were conducted to clarify factors associated with emotional exhaustion (EE), depersonalisation (DP) and personal accomplishment (PA). This study adheres to the STROBE guidelines., Results: Burnout prevalence varied from 10.0% to 22.0%. Most respondents (83.6%) reported low PA, 22.9% high EE and 18.7% high DP. Nurses and physicians had the highest levels of EE and DP. Staff exposed or uncertain if exposed to contaminated patients' body fluids and materials had higher levels of burnout. Preparedness (training) (b = 1.15; 95%CI 0.26 to 2.05) and adherence to infection prevention and control procedures (b = 1.57; 95%CI 0.67 to 2.47) were associated with higher PA, and accessibility of personal protective equipment (PPE) (b = -1.37; 95%CI -2.17 to -0.47) was related to lower EE. HCWs working in wards for patients with COVID-19 reported lower EE (b = -1.39; 95%CI -2.45 to -0.32). HCWs who contracted COVID-19 reported lower DP (b = -0.71, 95%CI -1.30 to -0.12)., Conclusions: Organisational factors such as better access to PPE, training, and adherence to infection prevention and control procedures were associated with a lower level of burnout., Relevance to Clinical Practice: Healthcare managers should promote strategies to reduce burnout among HCWs with regard to preparedness of all staff., (© 2023 John Wiley & Sons Ltd.)
