Authors: Pereda Loriente Álvaro , González-Calero José Antonio , Tirado-Olivares Sergio , del Olmo-Muñoz Javier 
Published: February 2025

Abstract
The use of technology and tools that enable the automation of personalized learning systems has become increasingly relevant and has attracted substantial attention in the field of research. Under this premise, the present study examines the potential of using personalized instructional sequences with activities in the Moodle learning management system on the learning of fractions and decimal numbers among 5th-grade primary school students. A total of 73 students participated in the study. This quantitative-experimental study was implemented over six sessions, in which the experimental and control groups completed personalized and non-personalized sequences of activities, respectively, on their assigned laptops at school. The results revealed significant improvement in both groups in the areas of fractions and decimal numbers. Additionally, when comparing the types of instruction, noteworthy differences were observed in favor of personalized instruction for fractions, but not for decimal numbers.
Parameter estimation and model selection for stochastic differential equations for biological growth
Authors: Baltazar-Larios Fernando , Delgado-Vences Francisco , Ornelas Arelly 
Published: February 2025

Abstract
In this paper, we consider the stochastic versions of three classical growth models given by ordinary differential equations (ODEs). Indeed we use the stochastic versions of Gompertz, von Bertalanffy, and logistic differential equations as models. We assume that each stochastic differential equation (SDE) has some crucial parameters to be estimated, and we use maximum likelihood estimation (MLE) to estimate them. For estimating the diffusion parameter, we use the MLE for two cases and the quadratic variation of the data for one of the SDEs. We apply the Akaike information criterion (AIC) to choose the best model for the simulated data. We consider that the AIC is a function of the drift parameter. We conduct numerical experiments to validate our selection method. Subsequently, we also apply it to actual data. The proposed methodology could be applied to datasets with discrete observations, including highly sparse data. Indeed, we can use this method even in the extreme case where we have observed only one point for each path, under the condition that we observed a sufficient number of trajectories. For the last two cases, the data can be viewed as incomplete observations of a model with a tractable likelihood function; then, we propose a version of the expectation maximization (EM) algorithm to estimate these parameters. This type of dataset typically appears in fishery, for instance.
Estimating effects of ocean environmental conditions on summer flounder (Paralichthys dentatus) distribution
Authors: Deen Samar , Jauss Verena , Sullivan Patrick J. 
Published: February 2025

Abstract
The relative abundance of summer flounder (Paralichthys dentatus) differs over space and time with changes in environmental factors, such as depth, bottom temperature, sea surface temperature (SST) and bottom salinity. We use the integrated nested Laplace approximation (INLA) approach to account for the random effects arising from either over-dispersion, or spatial and temporal autocorrelation. We explore how the different assumptions in the spatial temporal models result in varying model predictions. The results indicate that the distribution of summer flounder is correlated with depth, regional increases in bottom temperature, SST and bottom salinity. We find that in the Fall relative abundance increased 10–15% with a

Our study also shows that models that include spatio-temporally correlated variables can inadvertently be over parameterized when including higher order interaction terms between spatial and temporal random effects. This can lead to inflated variances in the estimates and predictions as well as lengthening model convergence times. Therefore, care should be taken in identifying the level of model complexity given the indirect implications of these results on fisheries management and marine ecology.
Application of Modular Architectures in the Medical Domain - a Scoping Review
Authors: Bathelt Franziska , Lorenz Stephan , Weidner Jens , Sedlmayr Martin , Reinecke Ines 
Published: February 2025

Abstract
The healthcare sector is notable for its reliance on discrete, self-contained information systems, which are often characterised by the presence of disparate data silos. The growing demands for documentation, quality assurance, and secondary use of medical data for research purposes has underscored the necessity for solutions that are more flexible, straightforward to maintain and interoperable. In this context, modular systems have the potential to act as a catalyst for change, offering the capacity to encapsulate and combine functionalities in an adaptable manner. The objective of this scoping review is to determine the extent to which modular systems are employed in the medical field. The review will provide a detailed overview of the effectiveness of service-oriented or microservice architectures, the challenges that should be addressed during implementation, and the lessons that can be learned from countries with productive use of such modular architectures. The review shows a rise in the use of microservices, indicating a shift towards encapsulated autonomous functions. The implementation should use HL7 FHIR as communication standard, deploy RESTful interfaces and standard protocols for technical data exchange, and apply HIPAA security rule for security purposes. User involvement is essential, as is integrating services into existing workflows. Modular architectures can facilitate flexibility and scalability. However, there are well-documented performance issues associated with microservice architectures, namely a high communication demand. One potential solution to this problem may be to integrate modular architectures into a cloud computing environment, which would require further investigation.
Unmet Spiritual Needs, Spiritual Wellbeing and Support Satisfaction of End-of-Life Patients: Findings from a Spiritual and Existential Care Training Program (SpECi) for Health Care Practitioners within Inpatient Geriatric Care, Palliative Care Units and Hospices
Authors: Büssing Arndt , Kloke Marianne , Gerundt Mareike 
Published: February 2025

Abstract
The outcomes of a 40-h Spiritual/Existential Care training program (SpECi) for healthcare professionals on their patients' treatment satisfaction (n = 774) were evaluated. Most patients felt supported in their spiritual needs by the staff (79–81%). This satisfaction was highest in hospices and palliative care units (Eta2 = .065, p < .001). Regression analyses revealed that satisfaction with spiritual needs support was predicted by therapeutic staff support, treatment place, and support from pastoral care providers (R2 = .17). The prominent role of healthcare practitioners with their specific competencies and spiritual care ideals is crucial for patients' support satisfaction which was higher for family and staff than to pastoral care providers.
Partial protection of Bacillus subtilis spores on simulated Martian media enhances survival against UV radiation

Published: February 2025

Abstract
Mars is known to have once sustained an environment that may have been habitable. This idea has often been combined with theories of panspermia, to suggest that any life on Mars may have had a common origin with life on Earth. These ideas typically involve meteorites produced as impact ejecta as vectors for the transport of life between planets. However, such meteorites would be subjected to the harsh conditions of space, most notably, Solar UV radiation. Some Gram-positive bacteria generate endospores, which provide protection from extreme conditions and are common models for understanding bacterial survival in space. In this study, the spore forming bacteria Bacillus subtilis and the non-spore former Staphylococcus aureus were used to investigate the survival of bacteria exposed to UVB and UVC radiation on simulated Martian regolith. Spore survival was limited upon excessive doses of UVB and UVC radiation, although this was minimised when spores were covered with lysed bacteria which provided partial protection. These results build upon previous studies and suggest that lysed bacteria from the same bacterial species might offer spores on Martian meteorites a partial shield from UV radiation and enhance their viability in panspermia models.
Similarities in mindset between adolescents’ friends and cooperation partners

Published: February 2025

Abstract
Peers, in terms of both friends and cooperation partners, are a very important aspect of the social context of adolescents. They may affect adolescents’ intelligence mindsets and therefore their school motivation and success. Being friends or cooperating with a peer with a similar mindset might either enhance (in case of a growth mindset) or hinder (in case of a fixed mindset) adolescents’ motivation to learn. In this cross-sectional social network study, we first examined whether friendship networks and cooperation partners networks within school classes differ from each other. Second, we investigated whether adolescents’ friends and cooperation partners have similarities in mindsets. We analysed peer nominations and intelligence mindsets within 26 Dutch classes of early and mid-adolescents (N = 558) using the quadratic assignment procedure (QAP). Our data showed that three unique networks could be distinguished: a friendship only network, a combined friends and cooperation partners network and a cooperation only network. Multiple regression quadratic assignment procedures (MRQAP) indicated no evidence for similarity in mindset in all the three networks. However, we did find that adolescents with a growth mindset select more peers to cooperate with than adolescents with a fixed mindset. This latter finding shows that mindset influences social interactions in the context of cooperation between adolescents. It might be valuable to take the social context into consideration in the development of new mindset interventions.
Directional data analysis: spherical Cauchy or Poisson kernel-based distribution?
Authors: Tsagris Michail , Papastamoulis Panagiotis , Kato Shogo 
Published: February 2025

Abstract
In 2020, two novel distributions for the analysis of directional data were introduced: the spherical Cauchy distribution and the Poisson kernel-based distribution. This paper provides a detailed exploration of both distributions within various analytical frameworks. To enhance the practical utility of these distributions, alternative parametrizations that offer advantages in numerical stability and parameter estimation are presented, such as implementation of the Newton–Raphson algorithm for parameter estimation, while facilitating a more efficient and simplified approach in the regression framework. Additionally, a two-sample location test based on the log-likelihood ratio test is introduced. This test is designed to assess whether the location parameters of two populations can be assumed equal. The maximum likelihood discriminant analysis framework is developed for classification purposes, and finally, the problem of clustering directional data is addressed, by fitting finite mixtures of Spherical Cauchy or Poisson kernel-based distributions. Empirical validation is conducted through comprehensive simulation studies and real data applications, wherein the performance of the spherical Cauchy and Poisson kernel-based distributions is systematically compared.
Describing posture on the bike: do different methods lead to similar outcomes?
Authors: Bini Rodrigo , Lanferdini Fabio , Diefenthaeler Fernando 
Published: February 2025

Abstract

Purpose
Standardising methods to calculate joint angles is essential to enable the reproducibility of movement analysis in cycling. This study compared three methods for determining lower limb posture on the bike across three positions on the saddle.

Methods
Fourteen non-cyclists were assessed in two laboratory visits. The first involved determining their maximum aerobic capacity which was used in the second visit to define a sub-maximal cycling exercise intensity. Lower limb kinematics were obtained and angles for the hip, knee, and ankle were calculated using three methods (6 o’clock position, minimum knee angle, and the largest lower limb extension). Two-way analysis of variance with repeated measurements was utilised for the hip, knee, and ankle data to assess the main effects from the method of measuring angles (i.e. 6 o’clock position vs. minimum knee angle vs. largest lower limb extension) and from positions on the saddle (i.e. anterior vs. reference vs posterior), followed by post-hoc analyses.

Results
The angles obtained at the 6 o’clock position were larger than those at the minimum knee angle and the largest lower limb extension for the hip, knee, and ankle joints (p < 0.01). Knee flexion was greater at the anterior position than the posterior and the reference, with larger angles for the reference than the posterior (p < 0.01). The ankle was more dorsiflexed at the anterior vs. posterior positions, anterior vs. reference positions, and references vs. posterior positions (p < 0.01).

Conclusion
All three methods were sensitive to detect changes in saddle position but data should not be interchanged due to differences in angles between methods. These results indicate that body position on the bike should always be described using a consistent method.

Published: February 2025

Abstract

Background
Endoscopic gastric pouch plications (EGPP) have emerged as a novel approach for managing weight-related issues and postoperative complications following bariatric surgery. However, safety for these revisions remains limited. This study aims to evaluate the 30-day rate of serious complications and mortality associated with EGPP using the MBSAQIP database.

Methods
A retrospective analysis of the MBSAQIP database from 2020 to 2022 was conducted, focusing on patients undergoing EGPP. The primary outcomes were 30-day serious complications and mortality.

Results
The study included 1474 patients. Recurrent weight gain was the most common indication for EGPP (71.9%), followed by suboptimal initial weight loss (15.1%), dumping syndrome (5.5%), reflux (4.1%), gastrointestinal tract fistula (1.0%), and others (0.9%). The mean operative time was 41.2 ± 35.2 min, with a mean hospital stay of 0.4 ± 0.7 days. Postoperative complications included 30-day readmissions (3.1%), serious complications (3.3%), 30-day interventions (2.5%), bleeding (0.8%), and reoperations (0.4%). The mortality rate was 0%. Multivariable analysis identified GERD as an independent predictor of serious complications (OR 1.79, 95% CI 0.98 to 3.2, p = 0.05) when adjusting for various factors.

Conclusions
EGPP is an uncommon procedure with only 1474 cases reported, primarily indicated for weight recurrence. It appears to be a relatively safe alternative to surgical revision. However, further research is needed to assess its efficacy and compare it to corresponding surgical revisions.
Lived experience of comfort with sexuality and fertility for survivors of hematopoietic progenitor cell transplants: phenomenological study
Authors: Bacalhau Lúcia , Pontífice-Sousa Patrícia 
Published: February 2025

Abstract

Introduction
Sexuality and fertility are deeply personal and fundamental aspects of human identity and quality of life. For survivors of hematopoietic stem cell transplants (HSCT), these areas can be profoundly affected by the physical, emotional, and social impacts of the treatment. Discomfort or lack of clarity regarding these issues can lead to long-term psychological distress, relationship challenges, and decreased overall well-being. Addressing this discomfort through research helps to fill a critical gap in supportive care, providing survivors with the tools and knowledge they need to navigate these challenges and enhance their post-treatment quality of life.

Purpose
To grasp the scope of sexuality and fertility within the lived experiences of comfort and discomfort among allogeneic stem cell transplant survivors.

Methods
We employed a qualitative approach through van Manen’s phenomenology of practice. The phenomenon was revealed via phenomenological interviews, incorporating narratives and illustrative episodes that captured the lived experiences of 20 survivors. We gathered descriptions of these experiences from participants from July 2020 to May 2021. During our phenomenological reflection on these accounts, we adhered to stages like epoché, reduction, and vocative, as outlined by van Manen (van Manen 2014).

Results
The exploration of comfort within the realms of sexuality and fertility yielded several themes: desire and the relationship; immunosuppression as a limitation on sexual activity; the body does not correspond to desire; the future: fertility and the couple’s relationship; the challenges of disclosure and intervention.

Conclusion
The findings indicate that survivors have long-term challenges with sexual expression and activity, stemming from the physical constraints of graft-versus-host disease (GVHD), perceptions of their immunosuppression, and the significance of their partnership, all of which translate into requirements for nursing care.

Implications for Care and Support Cancer Survivors
Considering the experiences of these participants and the observed comfort linked to the sexuality of ASCT survivors, we can contemplate the care practices and recognize sexuality as a field of action for nurses in this context to enhance comfort for these individuals.

Published: February 2025

Abstract

Purpose of Review
Our review emphasizes recent advancements and persisting gaps in cardiovascular genomics, particularly highlighting how emerging studies involving underrepresented populations have uncovered new genetic variants associated with cardiovascular diseases.

Recent Findings
Initiatives like the H3Africa project, the Million Veterans Program, and the All of Us Research Program are working to address this gap by focusing on underrepresented groups. Additionally, emerging research is centering on the interplay between genetic factors and socio-environmental determinants of health, which disproportionately impact marginalized communities.

Summary
As cardiovascular genomics research grows, increasing the inclusion of underrepresented populations is essential for gaining a more comprehensive understanding of genetic variability. This will lead to more accurate and clinically meaningful strategies for preventing and treating cardiovascular diseases across all ancestral backgrounds and diverse populations.
Differential Protective Effects of Edaravone in Cerebellar and Hippocampal Ischemic Injury Models

Published: February 2025

Abstract
Ischemic stroke is a leading cause of mortality and disability, with cerebellar strokes posing severe complications such as herniation and brainstem compression. Edaravone, a radical scavenger known for reducing oxidative stress, has shown neuroprotective effects in cerebral strokes, but its impact on cerebellar strokes remains unclear. This study investigates Edaravone’s protective properties in organotypic slice cultures of rat cerebellum and hippocampus, employing an oxygen-glucose deprivation (OGD) model to simulate ischemic stroke. The hippocampus served as comparative structure due to its high hypoxia sensitivity. Our results confirmed effective hypoxic induction with increases in HIF-1α and HIF-2α expression. Edaravone significantly reduced lactate dehydrogenase (LDH) levels, indicating diminished cellular damage, with cerebellar tissues showing greater vulnerability. Additionally, Edaravone reduced reactive oxygen species (ROS) in both tissues, though its efficacy may be limited by higher oxidative stress in cerebellar cultures. Seahorse XF analysis revealed that Edaravone preserved mitochondrial respiration and tissue integrity in cerebellar and hippocampal slice cultures. However, Edaravone was more effective in preserving mitochondrial respiration in hippocampal slices, suggesting that OGD-induced damage is more severe in cerebellar tissue. In conclusion, Edaravone demonstrates significant cell protective effects in both cerebellar and hippocampal tissues under OGD conditions, preserving tissue integrity and enhancing mitochondrial function in a tissue-dependent manner. These findings suggest Edaravone as a promising therapeutic candidate for cerebellar stroke. Further in vivo studies are required to assess its full clinical potential.

Abstract
Due to the military coups of recent years, the Sahel region has received some considerable attention in international media and political debates. However, we still know little about the ongoing disputes in the region. This article provides an overview of the current crisis in Burkina Faso, the Sahel state where the number of fatalities and internally displaced persons is by far the highest. The conflict is placed in the context of the country’s recent political history and in the debate surrounding the “coup belt”.
