Measuring empathic behaviour among undergraduate dietetics students

Ng SH, Babar MG, Ahmed SI, Hasan SS, Yang WY

J Eval Clin Pract, 2024 Mar;30(2):153-161.
PMID: 37641432 DOI: 10.1111/jep.13913

AIM: Empathic behaviour has a direct link to the positive clinical outcomes. Health professionals, which include dietitians, are increasingly expected to demonstrate the impact of their care on patient outcomes. To date, there is limited research exploring the empathic behaviour of dietetics students.
METHODS: This cross-sectional study evaluated the psychometric properties of Jefferson Scale of Empathy-Healthcare Provider Student (JSE-HPS) and empathic behaviour of dietetics students.
RESULTS: Undergraduate dietetics students from one private and two public universities in Malaysia participated (n = 455). Item and scale psychometric properties were examined using principal component analysis and differences in mean empathy scores for students were assessed across years of study and types of universities. A 3-factor solution emerged in the results, accounting for 26.76%, 10.75% and 6.3% of the variance. The JSE-HPS demonstrated good internal consistency (α = 0.83). Despite students enroled at public universities scoring higher mean empathy scores than students enroled at the private university, the difference was not significant. The only significant difference was between the empathy level of first and third year students (p = 0.033).
CONCLUSION: As empathy underpins patient-centred management in the nutrition care process, it should be well integrated into curriculum delivery so that appropriate levels of empathy can be developed to prepare work-ready healthcare professionals.

In recent years, the global health community has increasingly reported the problem of 'invisibility': aspects of health and wellbeing, particularly amongst the world's most marginalized and impoverished people, that are systematically overlooked and ignored by people and institutions in relative positions of power. It is unclear how to realistically manage global health invisibility within bioethics and other social science disciplines and move forward. In this letter, we reflect on several case studies of invisibility experienced by people in Brazil, Malaysia, West Africa and other transnational contexts. Highlighting the complex nature of invisibility and its interconnectedness with social, political and economic issues and trends, we argue that while local and targeted interventions might provide relief and comfort locally, they will not be able to solve the underlying causes of invisibility. Building from the shared lessons of case study presentations at an Oxford-Johns Hopkins Global Infectious Disease Ethics Collaborative (GLIDE), we argue that in dealing with an intersectional issue such as invisibility, twenty-first century global health bioethics could pursue a more 'disturbing' framework, challenging the narrow comforting solutions which take as a given the sociomaterial inequalities of the status quo. We highlight that comforting and disturbing bioethical frameworks should not be considered as opposing sides, but as two approaches working in tandem in order to achieve the internationally set global health milestones of providing better health and wellbeing for everyone. Insights from sociology, anthropology, postcolonial studies, history, feminist studies and other styles of critical reasoning have long been disturbing to grand narratives of people and their conditions. To rediscover the ethos of the WHO Alma Ata Declaration-a vision of "health for all by the year 2000"-these thinking tools will be necessary aids in developing cooperation and support beyond the narrow market logic that dominates the landscape of contemporary global health.

Addressing obesity and improving the diets of populations requires a comprehensive societal response. The need for broad-based action has led to a focus on accountability of the key factors that influence food environments, including the food and beverage industry. This paper describes the Business Impact Assessment-Obesity and population-level nutrition (BIA-Obesity) tool and process for benchmarking food and beverage company policies and practices related to obesity and population-level nutrition at the national level. The methods for BIA-Obesity draw largely from relevant components of the Access to Nutrition Index (ATNI), with specific assessment criteria developed for food and nonalcoholic beverage manufacturers, supermarkets, and chain restaurants, based on international recommendations and evidence of best practices related to each sector. The process for implementing the BIA-Obesity tool involves independent civil society organisations selecting the most prominent food and beverage companies in each country, engaging with the companies to understand their policies and practices, and assessing each company's policies and practices across six domains. The domains include: "corporate strategy," "product formulation," "nutrition labelling," "product and brand promotion," "product accessibility," and "relationships with other organisations." Assessment of company policies is based on their level of transparency, comprehensiveness, and specificity, with reference to best practice.
Fulltext Local human movement patterns and land use impact exposure to zoonotic malaria in Malaysian Borneo

Human movement into insect vector and wildlife reservoir habitats determines zoonotic disease risks; however, few data are available to quantify the impact of land use on pathogen transmission. Here, we utilise GPS tracking devices and novel applications of ecological methods to develop fine-scale models of human space use relative to land cover to assess exposure to the zoonotic malaria Plasmodium knowlesi in Malaysian Borneo. Combining data with spatially explicit models of mosquito biting rates, we demonstrate the role of individual heterogeneities in local space use in disease exposure. At a community level, our data indicate that areas close to both secondary forest and houses have the highest probability of human P. knowlesi exposure, providing quantitative evidence for the importance of ecotones. Despite higher biting rates in forests, incorporating human movement and space use into exposure estimates illustrates the importance of intensified interactions between pathogens, insect vectors and people around habitat edges.

Fulltext Conditioned media of pancreatic cancer cells and pancreatic stellate cells induce myeloid-derived suppressor cells differentiation and lymphocytes suppression

Chong YP, Peter EP, Lee FJM, Chan CM, Chai S, Ling LPC, et al.

Sci Rep, 2022 Jul 19;12(1):12315.

As pancreatic cancer cells (PCCs) and pancreatic stellate cells (PSCs) are the two major cell types that comprise the immunosuppressive tumor microenvironment of pancreatic cancer, we aimed to investigate the role of conditioned medium derived from PCCs and PSCs co-culture on the viability of lymphocytes. The conditioned medium (CM) collected from PCCs and/or PSCs was used to treat peripheral blood mononuclear cells (PBMCs) to determine CM ability in reducing lymphocytes population. A proteomic analysis has been done on the CM to investigate the differentially expressed protein (DEP) expressed by two PCC lines established from different stages of tumor. Subsequently, we investigated if the reduction of lymphocytes was directly caused by CM or indirectly via CM-induced MDSCs. This was achieved by isolating lymphocyte subtypes and treating them with CM and CM-induced MDSCs. Both PCCs and PSCs were important in suppressing lymphocytes, and the PCCs derived from a metastatic tumor appeared to have a stronger suppressive effect than the PCCs derived from a primary tumor. According to the proteomic profiles of CM, 416 secreted proteins were detected, and 13 DEPs were identified between PANC10.05 and SW1990. However, CM was found unable to reduce lymphocytes viability through a direct pathway. In contrast, CM that contains proteins secreted by PCC and/or PSC appear immunogenic as they increase the viability of lymphocytes subtypes. Lymphocyte subtype treated with CM-induced MDSCs showed reduced viability in T helper 1 (Th1), T helper 2 (Th2), and T regulatory (Treg) cells, but not in CD8+ T cells, and B cells. As a conclusion, the interplay between PCCs and PSCs is important as their co-culture displays a different trend in lymphocytes suppression, hence, their co-culture should be included in future studies to better mimic the tumor microenvironment.
An 11-country study to benchmark the implementation of recommended nutrition policies by national governments using the Healthy Food Environment Policy Index, 2015-2018

Vandevijvere S, Barquera S, Caceres G, Corvalan C, Karupaiah T, Kroker-Lobos MF, et al.

PMID: 30609260 DOI: 10.1111/obr.12819

The Healthy Food Environment Policy Index (Food-EPI) aims to assess the extent of implementation of recommended food environment policies by governments compared with international best practices and prioritize actions to fill implementation gaps. The Food-EPI was applied in 11 countries across six regions (2015-2018). National public health nutrition panels (n = 11-101 experts) rated the extent of implementation of 47 policy and infrastructure support good practice indicators by their government(s) against best practices, using an evidence document verified by government officials. Experts identified and prioritized actions to address implementation gaps. The proportion of indicators at "very low if any," "low," "medium," and "high" implementation, overall Food-EPI scores, and priority action areas were compared across countries. Inter-rater reliability was good (GwetAC2 = 0.6-0.8). Chile had the highest proportion of policies (13%) rated at "high" implementation, while Guatemala had the highest proportion of policies (83%) rated at "very low if any" implementation. The overall Food-EPI score was "medium" for Australia, England, Chile, and Singapore, while "very low if any" for Guatemala. Policy areas most frequently prioritized included taxes on unhealthy foods, restricting unhealthy food promotion and front-of-pack labelling. The Food-EPI was found to be a robust tool and process to benchmark governments' progress to create healthy food environments.
