Empathy in Professors and Students of a School of Dentistry in the Caribbean

Objective: To estimate and compare the levels of empathy between undergraduate dentistry students and professors at a university in the Dominican Republic. Material and Methods: Cross-sectional and descriptive study. The studied population consisted of two groups. The first: students of the Dentistry Career (N=520; n=335: 64.42% of total students) were distributed in two areas, basic-preclinical and clinical, while the second group corresponded of teachers who work in both areas (N=92; n=56; 60.87% of all teachers). The total sample was n = 391. The Jefferson Scale of Physician Empathy (S-Version) was used. Reliability was estimated using Cronbach's α and intraclass correlation coefficient, descriptive statistics, two-way analysis of variance, Tukey's test, effect size, and power of the test. Significance level: α ≤ 0.05 and β ≤ 0.20. Results: The empathy and dimension values were, in general, higher in the professors of the clinical area in relation to the other areas studied, with the exception of the compassionate care dimension. Conclusion: The finding that clinical teachers have a greater value of empathy is potentially an advantage for training students, especially in the clinical area

Keeping Us Grounded: Academic Staff Perceptions of Service User and Carer Involvement in Health and Social Work Training

Academic staff perceptions of the value and purpose of service user and carer (SUAC) involvement within a health and social work faculty in an English university were explored in this co-produced qualitative study. Relevant research findings over the past two decades were reviewed and two SUAC researchers, plus an academic member of staff, designed the study based around fifteen semi-structured telephone interviews. Findings were that staff were very positive about the benefits brought by SUAC involvement, in respect of their own grounding, knowledge, and continuing professional development (CPD), these findings not having previously been reflected in the literature. Barriers to involvement of SUACs were found to be negligible compared to those found in recent literature, and the input of SUACs appeared to be embraced by academic staff. This changing picture has emerged at a time when managerialism and marketization affect the working conditions of staff. In times of increasing workloads, this study suggested that academics find SUAC involvement both supportive and constructively challenging. SUACs were perceived to bring fresh interdisciplinary knowledge and challenges to staff value bases alongside constructs of professionalism that staff may not be able to access elsewhere. The encouragement of interdisciplinary ways of thinking was noted to have been a serendipitous consequence of SUACs from different backgrounds inputting on courses across the faculty. Recommendations are to better ensure consistency in the use of SUACs in terms of resourcing, support, and development if such involvement is to be meaningful rather than marginalised and de-valued

A empatia dos enfermeiros com os pacientes em hospitais públicos

Objective: to determine the levels of empathy in professional nurses of a high-complexity hospital, to relate age to empathy (and each one of its dimensions), and to establish if there are differences between these levels according to the type of working schedules. Method: comparative, correlational and cross-sectional design. The sample used (n=271) constituted 40.9% of the total number of nursing professionals. Psychometric properties of the Jefferson Scale of Empathy for Health Professionals were studied. Descriptive statistics were calculated: mean and standard deviation. The association between empathy and age was estimated using regression equations and statistical significance of the regression coefficients, after evaluating the type of curve using variance analysis. Results: the underlying model of three dimensions of empathy was identified. The values of the descriptive statistics observed were relatively low in empathy and its dimensions. Empathy levels were not associated with the age range. No differences in empathy were found between the types of work schedules. Variability was found in the dimensions: “compassionate care” and “Walking on the patient’s shoes”. Conclusion: these results show that the levels of empathy observed may imply a deficient performance in empathetic care for patients. Objetivo: determinar los niveles de empatía en profesionales de enfermería de un hospital de alta complejidad, relacionar la edad con la empatía (y cada una de sus dimensiones), y establecer si existen diferencias entre estos niveles según el tipo de jornada laboral. Método: diseño comparativo, correlacional y transversal. La muestra utilizada (n=271) constituyó el 40,9% del total de profesionales de enfermería. Se estudiaron las propiedades psicométricas de la Escala de Empatía de Jefferson para Profesionales de la Salud. Se calcularon estadísticos descriptivos: media y desviación estándar. La asociación entre empatía y edad se estimó mediante ecuaciones de regresión y significancia estadística de los coeficientes de regresión, luego de evaluar el tipo de curva mediante análisis de varianza. Resultados: se identificó el modelo subyacente de las tres dimensiones de la empatía. Los valores de los estadísticos descriptivos observados fueron relativamente bajos en empatía y sus dimensiones. Los niveles de empatía no se asociaron con el rango de edad. No se encontraron diferencias en la empatía entre los tipos de horarios de trabajo. Se encontró variabilidad en las dimensiones: “cuidado compasivo” y “ponerse en los zapatos del paciente”. Conclusión: estos resultados muestran que los niveles de empatía observados pueden implicar un desempeño deficiente en el cuidado empático de los pacientes.Objetivo: determinar os níveis de empatia em enfermeiros profissionais de um hospital de alta complexidade, relacionar a idade com a empatia (e cada uma das suas dimensões) e verificar se existem diferenças entre esses níveis, de acordo com o tipo de horário de trabalho.

Influencia De La Adición De Cobre En La Corrosión Del Cromado Metálico Para Aplicaciones En La Industria Automotríz

At present the use of metal coatings in the automotive industry is a priority so the present research had the objective of conducting studies of metallic chromium on surfaces of rings for buses applying national and international standards. The parameters of the coating process (time, temperature and voltage) are varied to check its incidence in corrosion by checking properties such as adhesion, hardness and layer thickness. It was determined that the optimum parameters for a nickel-chromium process are 60 min, 400 C and 7V, but with low corrosion resistance, so that an alternate coating was developed to add an alkaline copper layer, obtaining three layers, copper- nickel-chromium, thereby increasing corrosion resistance

The Helicobacter pylori Genome Project : insights into H. pylori population structure from analysis of a worldwide collection of complete genomes

Helicobacter pylori, a dominant member of the gastric microbiota, shares co-evolutionary history with humans. This has led to the development of genetically distinct H. pylori subpopulations associated with the geographic origin of the host and with differential gastric disease risk. Here, we provide insights into H. pylori population structure as a part of the Helicobacter pylori Genome Project (HpGP), a multi-disciplinary initiative aimed at elucidating H. pylori pathogenesis and identifying new therapeutic targets. We collected 1011 well-characterized clinical strains from 50 countries and generated high-quality genome sequences. We analysed core genome diversity and population structure of the HpGP dataset and 255 worldwide reference genomes to outline the ancestral contribution to Eurasian, African, and American populations. We found evidence of substantial contribution of population hpNorthAsia and subpopulation hspUral in Northern European H. pylori. The genomes of H. pylori isolated from northern and southern Indigenous Americans differed in that bacteria isolated in northern Indigenous communities were more similar to North Asian H. pylori while the southern had higher relatedness to hpEastAsia. Notably, we also found a highly clonal yet geographically dispersed North American subpopulation, which is negative for the cag pathogenicity island, and present in 7% of sequenced US genomes. We expect the HpGP dataset and the corresponding strains to become a major asset for H. pylori genomics

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
