In this work the maxillary central incisor is numerically analysed with an advance discretization technique--Natural Neighbour Radial Point Interpolation Method (NNRPIM). The NNRPIM permits to organically determine the nodal connectivity, which is essential to construct the interpolation functions. The NNRPIM procedure, based uniquely in the computational nodal mesh discretizing the problem domain, allows to obtain autonomously the required integration mesh, permitting to numerically integrate the differential equations ruling the studied physical phenomenon. A numerical analysis of a tooth structure using a meshless method is presented for the first time. A two-dimensional model of the maxillary central incisor, based on the clinical literature, is established and two distinct analyses are performed. First, a complete elasto-static analysis of the incisor/maxillary structure using the NNRPIM is evaluated and then a non-linear iterative bone tissue remodelling analysis of the maxillary bone, surrounding the central incisive, is performed. The obtained NNRPIM solutions are compared with other numerical methods solutions available in the literature and with clinical cases. The results show that the NNRPIM is a suitable numerical method to analyse numerically dental biomechanics problems.

An analysis of multilevel factor contributions to breast cancer screening inequities in an academic health system.
Cancer
February 2025
General Medicine Service, VA Puget Sound Health Care System, Seattle, Washington, USA.
Background: Breast cancer screening (BCS) inequities are evident at national and local levels, and many health systems want to address these inequities, but may lack data about contributing factors. The objective of this study was to inform health system interventions through an exploratory analysis of potential multilevel contributors to BCS inequities using health system data.
Methods: The authors conducted a cross-sectional analysis within a large academic health system including 19,774 individuals who identified as Black (n = 1445) or White (n = 18,329) race and were eligible for BCS.
Exploring Haemodialysis Nurses' Perceptions on Kidney Replacement Therapy Modality Education: A Framework Analysis.
J Ren Care
March 2025
Faculty of Nursing, University of Calgary, Calgary, Alberta, Canada.
Background: Many people with kidney failure start and remain on in-centre haemodialysis treatment despite evidence of improved outcomes with home dialysis. To make an informed modality decision patients must receive frequent, high-quality modality education. This education is inconsistent in the in-centre haemodialysis setting, where patients spend the most time with nurses while receiving haemodialysis treatments.

BMC Psychol
January 2025
Educational Psychology Department, Faculty of Education, Zagazig University, Sharkia, Egypt.
Background: Recent years have witnessed a revolutionary transformation in information technology, characterized by the proliferation of electronic information platforms, with the Egyptian Knowledge Bank being a notable example. Understanding how to effectively navigate these complex systems requires investigation into key factors, particularly system intelligence.
Objectives: This study aimed to examine the mediating role of research motivation in the relationship between system intelligence, Academic Grit, and Academic Achievement.
The association of travel distance and other patient characteristics with breast cancer stage at diagnosis and treatment completion at a rural Rwandan cancer facility.
BMC Cancer
January 2025
Brigham and Women's Hospital, 75 Francis Street, Boston, MA, 02115, USA.
Background: Butaro Cancer Center of Excellence (BCCOE) was founded to serve Rwanda's rural low-income population, providing subsidized cancer diagnosis and treatment with transport stipends for the lowest-income patients. We examined whether travel distance to BCCOE was associated with advanced-stage diagnoses and treatment completion.
Methods: We conducted a retrospective cohort study using medical record data from BCCOE patients with pathologically-confirmed breast cancer from 2012-2016.
Postnatal experiences of teenage mothers in selected communities in Central Region, Ghana: a phenomenological study.
BMC Public Health
January 2025
Department of Population and Health, College of Humanities and Legal Studies, University of Cape Coast, Cape Coast, Ghana.
Background: Teenage childbirth is an issue of social and public health concern in Ghana, with high prevalence in some regions, including the Central Region. There is a dire need to understand the experiences of teenagers beyond pregnancies to facilitate comprehensive sexual and reproductive health information and service provision. We explored the postnatal experiences of teenage mothers in five communities in the Central Region of Ghana.
