Nursing and midwifery students’ experiences of preceptorship in clinical education in Uganda: A preceptorship framework-informed qualitative study
(Elsevier, 2026-01) Brenda Mbabazi;; Patience Muwanguzi;; Connie Olwit ;; Catherine Lutalo Mwesigwa;; Joyce Nankumbi
Aim/objective: This study explored the experiences of final-year nursing and midwifery students at Mulago School of Nursing and Midwifery during their clinical placements. Background: Preceptorship plays a critical role in bridging the gap between theoretical learning and clinical practice in nursing and midwifery education. Design: A qualitative exploratory study design was conducted. Methods: Data were collected through six focus group discussions with final-year students and thematically analyzed using a deductive approach informed by the Preceptorship Framework. Results: Core themes as guided by the preceptorship framework included: communication, collaboration, contribution, commitment, competence and confidence. Students described preceptorship as an opportunity to engage in hands-on practice under the guidance of experienced professionals. Collaborative relationships with preceptors and other healthcare team members contributed to a sense of inclusion and learning through shared responsibilities. Students reported gaining confidence through progressive exposure to clinical tasks, supported decision-making, and constructive feedback. The development of clinical competence was closely linked to consistent mentorship, opportunities to observe best practices, and gradually assuming independent roles. Despite the experiences, some negative aspects of the experience emerged. Students reported being inadequately supervised or feeling used as substitutes for regular staff, which compromised the intended learning experience. Others expressed difficulty navigating inconsistent expectations and limited access to supportive mentors. These tensions, at times, created anxiety and hindered their ability to benefit from the clinical learning environment fully. Conclusions: These findings underscore the importance of strengthening the preceptorship structure to ensure consistent, learner-focused support that facilitates meaningful professional development in clinical settings.

Factors associated with malaria transmission in children aged 3 to 59 months during seasonal malaria chemoprevention implementation, Kotido District, Uganda, 2024

Introduction: Uganda introduced seasonal malaria chemoprevention (SMC) in the Karamoja region, an area where transmission of malaria is high. While SMC is effective in similar settings, 2023 surveillance data in Kotido District showed a 15% increase in malaria incidence among children during implementation. We investigated the factors driving transmission of malaria among children aged 3 to 59 months in Kotido and assessed SMC effectiveness. Methods: An unmatched 1:1 case-control study was conducted at three high-volume health facilities in Kotido in September 2024. Cases were children aged 3–59 months with parasitological’ confirmed malaria, while controls were children who tested negative for malaria at the same facilities, recruited concurrently. We conducted health facility exit interviews with caregivers of children to collect information on sociodemographic and clinical features. Logistic regression identified factors associated with malaria, and SMC effectiveness was computed as 1-adjusted odds ratio (aOR)*100. Results: We enrolled 272 cases and 272 controls. Most cases were female (141, 52%). More of the cases’ caregivers had a low malaria risk perception (64, 24%) compared to those of the controls (10, 4%). SMC provided a 94% (95% CI: 91%–96%) protection against malaria in children who took it within 28 days of the previous cycle. Children who had spent more than the recommended 28 days without SMC administration (adjusted odds ratio [aOR] = 17, 95%CI = 11–26), those with underlying medical conditions (aOR = 1.6, 95% CI = 1.02–2.5), and those whose caregivers had a low malaria risk perception (aOR = 5.0, 95% CI=2.3–11) were at a higher risk of getting malaria. Conclusion: Children who did not adhere to the 28-day SMC schedule, had existing health conditions, or whose caregivers perceived malaria as low risk had increased odds of contracting malaria. Strengthening adherence to SMC schedules, providing integrated care for children, and enhancing caregiver awareness could maximize SMC effectiveness and sustain malaria control efforts.

Deep Learning for Automated Detection of Periportal Fibrosis in Ultrasound Imaging: Improving Diagnostic Accuracy in Schistosoma mansoni Infection
(MDPI AG, 2025-12-12) Alex Mutebe;; Bakhtiyar Ahmed;; Agnes Natukunda ;; Emily Webb;; Andrew Abaasa;; Simon Mpooya;; Moses Egesa;; Ayoub Kakande;; Alison M. Elliott;; Samuel O. Danso
This study investigates advanced deep learning methods to improve the detection of periportal fibrosis (PPF) in medical imaging. Schistosoma mansoni infection affects over 54 million individuals globally, predominantly in sub-Saharan Africa, with around 20 million experiencing chronic complications. PPF, present in up to 42% of these cases, is a leading outcome of chronic liver disease, significantly contributing to morbidity and mortality. Early and accurate detection is critical for timely intervention, yet conventional ultrasound diagnosis remains highly operator-dependent. We adapted and trained a convolutional neural network (CNN) using ultrasound images to automatically identify and classify PPF severity. The proposed approach achieved a diagnostic accuracy of 80%. Sensitivity and specificity reached 84% and 76%, respectively, demonstrating robust generalisability across varying image qualities and acquisition settings. These findings highlight the potential of deep learning to reduce diagnostic subjectivity and support scalable screening programmes. Future work will focus on validation with larger datasets and multi-class fibrosis grading to enhance clinical utility.

Local species richness of parasitoid wasps (Ichneumonidae: Pimplinae) in Afrotropical forest: Conservation perspectives
(Wiley Subscription Services, Inc, 2026-01) Österman, Emil M.;; Hopkins, Tapani;; Sääksjärvi, Ilari E.
Effective conservation of biodiversity relies on an understanding of its composition and distribution. Parasitoid wasps are an ecologically important and highly species‐rich group of Hymenoptera but are poorly known in the tropics. One strategy for conserving their richness is based on finding out how the richness is distributed in different habitats. Here, we investigate the local species richness and biological composition of parasitoid wasps (Ichneumonidae: Pimplinae) collected with Malaise traps in Ugandan tropical forest. We link the richness of Pimplinae and its four biological groups to habitat types across a successional gradient. We found higher pimpline richness in forest than in nearby farmland, with the highest richness in the group of idiobiont parasitoids of weakly concealed hosts. Our results suggest that protecting primary tropical forest may be particularly important for conserving a high richness of koinobiont ectoparasitoids of spiders and that nearby disturbed forest can have high parasitoid wasp richness after a few decades of regeneration. Trapping in forest collected 5623 individuals of 83 species, which is high compared with pimpline richness at temperate latitudes, supporting a typical latitudinal diversity gradient of at least the Pimplinae subfamily of Ichneumonidae.

Parental death: a systematic review of support experiences and needs of children and parent survivors
(British Medical Journal Publishing Group, 2026-01) Wray, Alexandra;; Pickwell-Smith, Benjamin;; Greenley, Sarah ;; Pask, Sophie;; Bamidele, Olufikayo;; Wright, Barry;; Murtagh, Fliss;; Boland, Jason W
BackgroundBereaved people need a supportive response from those around them. Knowing children’s and surviving parents' needs following parental death is the first step to ensuring a supportive response. However, no systematic review has reported on this phenomenon.AimTo systematically identify and synthesise qualitative literature exploring support experiences of parentally bereaved children and surviving parents.MethodsSystematic review with thematic synthesis, following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. MEDLINE, Embase, PsycINFO, CINAHL and the British Nursing Database were searched for relevant papers to September 2021. Included studies were appraised for quality and thematically synthesised using Thomas and Harden’s thematic synthesis framework.ResultsFifteen qualitative studies from nine countries were included. There were four analytical themes from the children’s perspectives (1) Openness of communication with children about death and dying, (2) Children’s challenges of managing change, (3) Navigating emotions, and (4) Children’s acceptability, access and engagement with support. There were three analytical themes from the parents' perspectives: (1) Adjusting as a parent, (2) Supporting their children, and (3) Parent’s acceptability, access and engagement with support.ConclusionsFollowing a parental death, open and honest communication and involvement in what is happening within the family will help children cope. Both children and parents suppress emotions and avoid conversations to protect each other and those around them. A taboo around death exists and constrains the support some families receive. Childhood bereavement is a public health issue, with a need for professionals and communities to better understand and respond to the needs of bereaved families.CRD42020166179
