- Exploring how research skills are taught and assessed in medical imaging and radiation therapy higher education: an international snapshotPublication . Di Michele, L.; Johnson, N.; McDermott, B.; Podkrajšek, M.; Ranshi, R.; Silva, I.; Vieira, Lina Oliveira; Ghotra, S.S.Introduction: Research competence is a core attribute of contemporary medical imaging and radiation therapy (MIRT); however, how research skills are taught and assessed across international radiography programs remains poorly understood. This study aims to explore research skills that are taught and assessed in different medical imaging and radiation therapy (MIRT) higher education institutions internationally, focusing on the curricula, experience of students, and academics. Methods: A two-phase design study was employed. Phase one involved an analysis of undergraduate MIRT curricula from nine international higher education institutions, examining programme structure, research credit allocation, research-related subjects, and teaching strategies. Phase two consisted of semi-structured focus groups with students and academic staff. All sessions were audio-recorded and transcribed using Zoom, with the transcripts checked for accuracy, and analysed using reflexive thematic analysis supported by NVivo software. Results: Data were collected from nine institutions across three continents. Curriculum analysis revealed international variability in the scope, timing, and depth of research integration, with research-related content embedded at differing stages of training. Reflexive thematic analysis identified three overarching themes: 1. research skills in the curriculum, 2. Navigating the research learning experience, and 3. Professional identity and practice. Conclusion: This study demonstrates substantial international variability in research education for medical imaging and radiation therapy students, leading to differences in research capability among graduates. Importantly, research education also shapes how practitioners value and engage with research, influencing professional culture within the field. Impacts on practice: Systematically scaffolding research skills across undergraduate radiography programs can support progressive learning and promote sustained engagement with research throughout the curriculum. Embedding clinically relevant research throughout education can sustain engagement with research, strengthening evidence-based practice and supporting a professional culture that values research in MIRT practice.
- Sickle cell disease: can genetic variability influence pregnancy outcomes?Publication . Ginete, Catarina; Cruz, Carolina; Delgadinho, Mariana; Mendes, Manuela; Simão, Fernanda; Alves, Ligia; Vasconcelos, Jocelyne; Borralho, Paula; Brito, MiguelPregnancy in Sickle Cell Disease (SCD), a severe hereditary genetic condition, highly prevalent in Sub-Saharan African countries, is associated with increased risk of complications and severe outcomes in pregnancy, like intrauterine growth restriction, low birth weight, premature birth, miscarriage, stillbirth, pre-eclampsia, and maternal mortality. Several factors have been identified as associated with the heterogeneity of SCD phenotypes, namely the hemoglobin subunit beta (HBB) haplotype and −3.7 kb α-thalassemia deletion. Objective: This study aimed to identify pregnancy complications and severe outcomes, and their association with genetic variability in women with SCD. Methods: In a cohort of 162 pregnant women followed at Maternidade Lucrécia Paim, Luanda, Angola, we collected clinical, hematological, biochemical, and genetic data (Sickle Cell Disease genotype, HBB haplotype, and −3.7 kb α-thalassemia). Findings: The Central African Republic (CAR) haplotype was the most prevalent, being 87% of women homozygous. For the −3.7 kb α-gene deletion, 11.7% of women were homozygous, and 36.4% were heterozygous. In this cohort, CAR/CAR women had over 9 times higher odds of having a premature birth, and homozygous women for the −3.7 kb α-thalassemia had over four times higher odds of having a livebirth than the other genotypes. Over 50% of babies were born with low birth weight, and 52,7% were considered premature. Severe maternal complications were registered in 68% of current pregnancies. Conclusion: These findings highlight the high burden of adverse outcomes in SCD pregnancy and the need for individualized and closer healthcare, especially in low and middle-income countries.
