Abstract

There is growing concern about radiation exposure from nuclear myocardial perfusion imaging (MPI), particularly among younger patients who are more prone to develop untoward effects of ionizing radiation, and hence US and European professional society guidelines recommend age as a consideration in weighing radiation risk from MPI. We aimed to determine how patient radiation doses from MPI vary across age groups in a large contemporary international cohort.Data were collected as part of a global cross-sectional study of centers performing MPI coordinated by the International Atomic Energy Agency (IAEA). Sites provided information on each MPI study completed during a single week in March-April 2013. We compared across age groups laboratory adherence to pre-specified radiation-related best practices, radiation effective dose (ED; a whole-body measure reflecting the amount of radiation to each organ and its relative sensitivity to radiation's deleterious effects), and the proportion of patients with ED ≤ 9 mSv, a target level specified in guidelines.Among 7911 patients undergoing MPI in 308 laboratories in 65 countries, mean ED was 10.0 ± 4.5 mSv with slightly higher exposure among younger age groups (trend p value 0.001). There was no difference in the proportion of patients with ED ≤ 9 mSv across age groups, or in adherence to best practices based on the median age of patients in a laboratory.In contemporary nuclear cardiology practice, the age of the patient appears not to impact protocol selection and radiation dose, contrary to professional society guidelines.

Abstract

Purpose Nuclear cardiology is widely used to diagnose coronary artery disease and to guide patient management, but data on current practices, radiation dose-related best practices, and radiation doses are scarce. To address these issues, the IAEA conducted a worldwide study of nuclear cardiology practice. We present the European subanalysis. Methods In March 2013, the IAEA invited laboratories across the world to document all SPECT and PET studies performed in one week. The data included age, gender, weight, radiopharmaceuticals, injected activities, camera type, positioning, hardware and software. Radiation effective dose was calculated for each patient. A quality score was defined for each laboratory as the number followed of eight predefined best practices with a bearing on radiation exposure (range of quality score 0 - 8). The participating European countries were assigned to regions (North, East, South, and West). Comparisons were performed between the four European regions and between Europe and the rest-of-the-world (RoW). Results Data on 2,381 European patients undergoing nuclear cardiology procedures in 102 laboratories in 27 countries were collected. A cardiac SPECT study was performed in 97.9 % of the patients, and a PET study in 2.1 %. The average effective dose of SPECT was 8.0 +/- 3.4 mSv (RoW 11.4 +/- 4.3 mSv; P < 0.001) and of PET was 2.6 +/- 1.5 mSv (RoW 3.8 +/- 2.5 mSv; P < 0.001). The mean effective doses of SPECT and PET differed between European regions (P < 0.001 and P = 0.002, respectively). The mean quality score was 6.2 +/- 1.2, which was higher than the RoW score (5.0 +/- 1.1; P < 0.001). Adherence to best practices did not differ significantly among the European regions (range 6 to 6.4; P = 0.73). Of the best practices, stress-only imaging and weight-adjusted dosing were the least commonly used. Conclusion In Europe, the mean effective dose from nuclear cardiology is lower and the average quality score is higher than in the RoW. There is regional variation in effective dose in relation to the best practice quality score. A possible reason for the differences between Europe and the RoW could be the safety culture fostered by actions under the Euratom directives and the implementation of diagnostic reference levels. Stress-only imaging and weight-adjusted activity might be targets for optimization of European nuclear cardiology practice.

Abstract

Comparison of Latin American (LA) nuclear cardiology (NC) practice with that in the rest of the world (RoW) will identify areas for improvement and lead to educational activities to reduce radiation exposure from NC. INCAPS collected data on all SPECT and PET procedures performed during a single week in March-April 2013 in 36 laboratories in 10 LA countries (n = 1139), and 272 laboratories in 55 countries in RoW (n = 6772). Eight “best practices” were identified a priori and a radiation-related Quality Index (QI) was devised indicating the number used. Mean radiation effective dose (ED) in LA was higher than in RoW (11.8 vs 9.1 mSv, p

Abstract

Aims To characterize patient radiation doses from nuclear myocardial perfusion imaging (MPI) and the use of radiation-optimizing ‘best practices’ worldwide, and to evaluate the relationship between laboratory use of best practices and patient radiation dose. Methods and results We conducted an observational cross-sectional study of protocols used for all 7911 MPI studies performed in 308 nuclear cardiology laboratories in 65 countries for a single week in March–April 2013. Eight ‘best practices’ relating to radiation exposure were identified a priori by an expert committee, and a radiation-related quality index (QI) devised indicating the number of best practices used by a laboratory. Patient radiation effective dose (ED) ranged between 0.8 and 35.6 mSv (median 10.0 mSv). Average laboratory ED ranged from 2.2 to 24.4 mSv (median 10.4 mSv); only 91 (30%) laboratories achieved the median ED ≤ 9 mSv recommended by guidelines. Laboratory QIs ranged from 2 to 8 (median 5). Both ED and QI differed significantly between laboratories, countries, and world regions. The lowest median ED (8.0 mSv), in Europe, coincided with high best-practice adherence (mean laboratory QI 6.2). The highest doses (median 12.1 mSv) and low QI (4.9) occurred in Latin America. In hierarchical regression modelling, patients undergoing MPI at laboratories following more ‘best practices’ had lower EDs. Conclusion Marked worldwide variation exists in radiation safety practices pertaining to MPI, with targeted EDs currently achieved in a minority of laboratories. The significant relationship between best-practice implementation and lower doses indicates numerous opportunities to reduce radiation exposure from MPI globally.

Abstract

Objective: To conduct a rapid knowledge synthesis of literature on the social determinants of mental health of racialized women exposed to gender-based violence (GBV) during the COVID-19 pandemic., Methods: We adapted the Cochrane Rapid Reviews method and were guided by an equity lens in conducting rapid reviews on public health issues. Four electronic databases (Cochrane CENTRAL, Medline, ProQuest, and EBSCO), electronic news media, Google Scholar, and policy documents were searched for literature between January 2019 and October 2020 with no limitations for location. Fifty-five articles qualified for the review., Results: Health emergencies heighten gender inequalities in relation to income, employment, job security, and working conditions. Household stress and pandemic-related restrictions (social distancing, closure of services) increase women's vulnerability to violence. Systemic racism and discrimination intensify health disparities., Conclusion: Racialized women are experiencing a 2020 Syndemic: a convergence of COVID-19, GBV, and racism pandemics, placing their wellbeing at a disproportionate risk. GBV is a public health issue and gender-responsive COVID-19 programming is essential. Anti-racist and equity-promoting policies to GBV service provision and disaggregated data collection are required., (© 2021. The Author(s).)

Abstract

Background: Arts-based educational methodologies have been implemented in nursing and other health disciplines to promote person-centered approaches to care. Readers Theatre has been applied as a tool to promote compassionate and holistic approaches to care. Readers Theatre is a form of drama that requires participants to read aloud a scripted narrative to the audience., Objectives: To examine the extant literature on experiences of adult learners and educators in utilizing Readers Theatre, and its potential suitability for nurse education. The review question was: "What are the learning experiences of adult students and the teaching experiences of educators in the uptake of Readers Theatre?", Design and Data Sources: Scoping review guidelines proposed by Arksey and O'Malley were adopted. Academic databases searches were carried out in ProQuest, JSTOR, Scholars Portal, EBSCO, Web of Science, PubMed, Expanded Academic ASAP, and Scopus., Review Methods: The search and keyword strategy was developed by two reviewers and approved by the lead author, and a librarian. All titles and abstracts were individually examined by the two reviewers with discrepancies discussed and resolved by both parties. Data were extracted for thematic analysis., Results: A total of 31 studies were selected for the final sample. Four themes were identified within the scoping review relevant to Readers Theatre teaching-learning experiences: 1) principles and characteristics; 2) awareness, understanding, caring and empathy; 3) cross-disciplinary collaboration, interdisciplinary education, and knowledge dissemination; and 4) promoting students' skills., Conclusions: Readers Theatre has the potential to be utilized within a nursing curriculum, and particularly in theory and substantive class-based courses, through active group learning, in the application phase of knowledge acquisition., (Copyright © 2022 The Authors.

Abstract

We discuss strategies to promote the inclusion of people with developmental disabilities (DDs) in qualitative community-based research studies. Strategies were applied in three projects conducted between 2012 and 2017 that addressed issues of socioeconomic challenges, discrimination, and exclusion of children and young adults with developmental disabilities (YADD). Strategies included partnership with community organizations; inclusion of YADD, family caregivers (FCs), and service providers in advisory committees (ACs); and strategies to accommodate YADD. As part of our contribution, we discuss issues of invisibility and exclusion of individuals with DDs who have "low" functioning capacities. There is a need to review studies sampling inclusion criteria as they may constitute a barrier for participation. Preference for sampling "high" functioning individuals may reinforce exclusion in research, and replicate broader patterns of socioeconomic exclusion of individuals with disabilities. Our discussion of inclusive research is informed by critical disability studies and the underlying principle "nothing about us without us."

Abstract

We present findings of a qualitative study exploring what constitutes relevant health promotion initiatives for immigrant mothers of children with developmental disabilities. We apply a social ecological approach, with a focus on gender-specific and transformative health promotion, to examine factors impacting mothers' health and wellbeing. Twenty-eight semi-structured and open-ended interviews were conducted with immigrant mothers in the greater Toronto area, Canada. Mothers identified facilitators, challenges, and strategies for their health promotion, providing relevant insights for meaningful intervention. Our findings show that immigrant mothers' health is influenced by intersecting social determinants of health, including migration status, gender, and disability.

Abstract

Equal access for autism services remains suboptimal for diverse groups. In Canada, little is known about the barriers immigrant mothers face accessing services and support for their children with developmental disabilities. In this qualitative study, 21 immigrant mothers of children with Autism, from a diverse ethno cultural background, were interviewed in Toronto, Canada. We apply House's (1981) four domains of social support to analyze findings. Structural support challenges, such as delays in diagnosis, fragmented and dispersed services were common, followed by instrumental challenges due to loss of social ties and stigma. Lack of expected support from partners, and negative perceptions of services, were identified as emotional and perceptive challenges. Focused attention is required to address inequalities within the context of current access pathways for autism.

Abstract

Background: Community associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is one of the most common causes of skin and soft tissue infections in the United States, and a variety of genetic host factors are suspected to be risk factors for recurrent infection. Based on the CDC definition, we have developed and validated an electronic health record (EHR) based CA-MRSA phenotype algorithm utilizing both structured and unstructured data., Methods: The algorithm was validated at three eMERGE consortium sites, and positive predictive value, negative predictive value and sensitivity, were calculated. The algorithm was then run and data collected across seven total sites. The resulting data was used in GWAS analysis., Results: Across seven sites, the CA-MRSA phenotype algorithm identified a total of 349 cases and 7761 controls among the genotyped European and African American biobank populations. PPV ranged from 68 to 100% for cases and 96 to 100% for controls; sensitivity ranged from 94 to 100% for cases and 75 to 100% for controls. Frequency of cases in the populations varied widely by site. There were no plausible GWAS-significant (p < 5 E -8) findings., Conclusions: Differences in EHR data representation and screening patterns across sites may have affected identification of cases and controls and accounted for varying frequencies across sites. Future work identifying these patterns is necessary.

13. Stressors and Barriers to Services for Immigrant Fathers Raising Children with Developmental Disabilities.

Author

Khanlou N, Mustafa N, Vazquez LM, Haque N, and Yoshida K

Abstract

This narrative review examines research on the experiences of immigrant fathers raising children with developmental disabilities, and considers the findings within the Canadian context. Applying Green, Johnson & Adams' ( Journal of Chiropractic Medicine , 5(3), 101-117, 2006) methodology, a step-by-step process was followed to conduct the review. Four databases (PsychINFO, PubMed, CINAHL and Sociological Abstracts) were used for the search. A total of 39 articles were found to be relevant after applying the inclusion/exclusion criteria. Also 20 articles from published reference lists and peer-reviewed journal articles, located through Google Scholar, complimented the initial search. Along with House's (1981) four dimensions of social support, an intersectional approach underpinned the analysis of findings. Four themes were identified which included: economic challenges, social influences, cultural influences, and the changing gender roles of fathers. Stressors and barriers to accessing health services in the post-migration setting were examined. Based on the review's findings, the paper recommends 1) addressing income inequality, 2) improving access to health care, social and developmental services, 3) improving cultural-sensitivity of health care, social and developmental services, and 4) increasing participation of fathers. Overall, a more systemic understanding of immigrant fathers' experiences is called for, taking into account their multiple social locations.

Abstract

The Mediterranean Region is the major area devoted to olive tree crop, and therefore a study of olive flowering is of great interest for the European Community. On the other hand, olive pollen is one of the main causes of pollen allergy in the Mediterranean area. Olive flowering is affected by climatic factors such as temperature and photoperiod, which vary geographically in latitude and altitude. Temperature has been used to study those processes that lead to flowering in the olive tree. The aim of the present paper is firstly the comparison of the flowering full bloom dates in two Mediterranean areas, Sicily (Italy) and Cordoba (Spain), located in the same latitudinal band (37-38 degrees N) and to calculate the heat requirement until flowering by determination of different threshold temperatures and methods of heat accumulation. A delay of the full flowering dates in the Spanish compared with the Italian olive groves was observed. The most suitable threshold temperatures were carried out in a 7 degrees -15 degrees C range by considering the heat accumulation start on 1 January in each olive grove. In particular, some causes were indicated as responsible for the different threshold temperatures recorded in the 2 study areas: First, the different climatic conditions (continental and insular climate) secondly the different cultivars present in the olive groves.
