Published: December 2024

Objective: The purpose of this study was to determine the quality and effectiveness of a structured, competency milestone-based pediatric sonographer onboarding program and continuing educational curriculum and to ascertain if these experiences influence their professional development, job satisfaction, and retention. Materials and Methods: A survey was distributed to the sonographers in a single echocardiography laboratory. The anonymized data were collected and analyzed to generate descriptive statistics. Results: There were 36 sonographers who responded (80%) and 15 (42%) training with the new onboarding curriculum. The majority reported a positive feeling of preparedness for independent practices (80%) with hands-on teaching, timely feedback, and case-based learning rated as the most effective teaching methods. Physician feedback was preferred over sonographer trainer feedback. Most sonographers perceived the advancement of their knowledge as important for professional growth, job satisfaction, and retention. Conclusion: A structured onboarding program for new hires based on competency milestones was effective in preparing pediatric cardiac sonographers for independent practice. Hands-on bedside training, timely constructive feedback, and case-based learning should be included in the curriculum to ensure high-quality teaching. Physician engagement is highly valued and should be incorporated into the workflow. This study may suggest that continuing education helps positively influence the sonographer’s attitudes toward professional development, job satisfaction, and retention.

Published: December 2024

AbstractThin copper substrates with high accuracy are highly required in precision physical experiments. However, even using double-sided lapping, the flatness is still limited due to the accuracy of lapping plate, process vibration and so on. Hence, as a subsequent process, this paper employs magnetorheological finishing (MRF) to further improve the flatness. Nevertheless, thin copper substrates, which are sensitive to the stress, deformed easily with uneven material removal on the surface. Therefore, MRF is adopted on machining thin copper substrate for the first time considering deformation induced by stress. A finite element model is established to evaluate the deformation by residual stress, and the results show that the deformation tends to be more serious with the increase of the material removal. According to the simulation results, the material removal is optimized considering both deformation and efficiency, and a series of experiments are conducted on a Φ100×2.8 mm workpiece to verify the simulation results. The experimental results show that the flatness is further improved from peak to valley (PV) 6.6 μm to PV 2.3 μm with optimized processing parameters. Hence, the feasibility of magnetorheological finishing on thin copper substrate is demonstrated.

Abstract
Background
Citizen Science (CS) offers a promising approach to enhance data collection and engage communities in conservation efforts. This study evaluates the use of CS in environmental DNA (eDNA) monitoring for Mediterranean monk seal conservation. We validated CS by assessing the effectiveness of a newly developed CS-friendly filtration system called “WET” (Water eDNA Trap) in eDNA detection, addressing technical challenges, and analysing volunteer faults. The WET is a 4-litre, manual pump-based filtering system using positive pressure to force water through the filter. We also assessed the use of a retrospective questionnaire as a tool to measure CS’s social impact on participants’ perceived knowledge, attitudes, and conservation behaviours.

Results
Results suggest the WET performs comparably to traditional methods, with minor technical issues. Despite some faults such as not folding or forgetting to change the filter, volunteers were generally reliable in sample processing. Moreover, CS involvement increased participants’ perceived knowledge, affective attitudes, and conservation behaviours towards seal conservation. Volunteers reported a greater understanding of eDNA monitoring, increased interest in monk seal conservation, and more frequent conservation behaviours, including spreading awareness within their community. While these findings are exploratory due to the small sample size (19 participants) and potential ceiling effects in attitude assessment, they provide an initial validation of the questionnaire as a tool for measuring CS’s social outcomes. Future studies with larger sample sizes are needed to confirm these results and investigate their applicability across broader stakeholder groups. Continuous improvement in volunteer training and equipment design is also recommended.

Conclusions
This study highlights CS’s potential to improve public engagement and knowledge in conservation. By involving diverse participants, CS can play a critical role in long-term conservation efforts and promote sustainable coexistence between humans and monk seals. Furthermore, the validation of the questionnaire offers a valuable framework for evaluating the social impact of CS initiatives in conservation contexts.
Context counts: a qualitative study on how adolescents activate social resources to develop and practice health literacy

Published: December 2024

Abstract
Background
Recently, the importance of social networks and other contextual factors in shaping health literacy of adolescents has gained recognition. However, research often simply refers to context without explicitly describing it. In this qualitative study, we aimed to explore how adolescents activate their (social) resources to develop and practice health literacy within a Swiss cantonal school health service program and in their everyday lives.

Methods
This study is based on a secondary analysis of interviews from an evaluation of the school health service in the canton of Zug, focusing on the final health screening in the 7th grade (corresponding to an average age of 14 years). Semi-structured interviews were conducted with 16 students. The data was analyzed using thematic analysis and constructivist grounded theory to identify and refine key themes.

Results
Our analysis revealed that adolescents’ interactions with their social networks, including family members, teachers, healthcare providers, and peers, were significant resources in their health literacy practices. Other resources included school health services, regular curricula and the internet. The activation of these resources was moderated by several factors that functioned as activators or deactivators, which we divided into three categories: relationships, health system, and pre-existing health literacy. Prominent activators in the category relationships involved good rapport and trust, whereas fear of judgment deactivated resources. In the category health system, access to resources as well as opportunities for participation in dealing with health information, challenges and services were important activators (or when missing, deactivators). Finally, participants demonstrated that pre-existing health literacy in the form of pre-existing knowledge and motivation and attitudes served as an activator of their resources to develop and practice health literacy in a ‘virtuous circle’. Thus, although health literacy development and practice were dependent upon their social networks, adolescents played key roles as active agents while navigating health.

Conclusions
Our findings highlight potential (de)activators of adolescents’ resources, primarily those available within their social networks, in the development and practice of health literacy. Results contribute to the literature on adolescent health literacy by shedding light on the often under-described concept of context. Explicit consideration of context provides actionable insights for educators, healthcare providers, and policymakers seeking to support adolescents in the development and practice of health literacy.
Understanding the contribution of primary and community services to health system resilience during the COVID19 Pandemic in Aotearoa, New Zealand: a qualitative interview study
Authors: Burholt Vanessa , Wiles Janine , Schneller Alison 
Published: December 2024

Abstract
Background
The COVID-19 pandemic exposed critical gaps in health system preparedness. This study, guided by a critical ecological model, examines the experiences of primary health and community services in Aotearoa New Zealand during the pandemic, focusing on their response to older people and their unpaid caregivers. The study aims to identify effective strategies for health system resilience. It addresses the question, what can we learn from the experiences of organisations supporting older people and caregivers during COVID-19, to prepare for other similar (emergency health) situations?

Methods
A multidisciplinary research team conducted cross-sectional qualitative research through semi-structured telephone interviews with service providers (SPs) delivering primary or community home-based services to older people and caregivers across Aotearoa New Zealand. SPs included national organisations, Māori, Pacific, or rural providers and dementia services. Data were collected between July and October 2020. Notes were taken during interviews using a Rapid Appraisal Procedure grid, which were later revised and validated by participants. Data were analysed using a hybrid deductive-inductive thematic analysis, following COREQ guidelines.

Results
Twenty staff (Chief Executive Officers and representatives) from national organisations (N = 4), Māori (N = 3), Pacific (N = 5), rural (N = 4), and regional dementia (N = 4) SPs were interviewed. SPs demonstrated resilience through collaboration, adapting delivery models, and upskilling staff. Key challenges involved inconsistent identification of vulnerable clients, limited access to aged residential care, and barriers relating to digital access which disproportionately affected older adults and staff, and clients in rural areas. Workforce shortages, and unclear public policy concerning travel across regions further complicated service delivery, highlighting the interaction between policy, community, interpersonal, and individual factors.

Conclusions
Aotearoa New Zealand managed COVID-19 effectively, but the pandemic exposed areas for improvement in health system resilience. The government demonstrated absorptive resilience through swift actions, including lockdowns and clear communication, while SPs exhibited adaptive resilience by modifying service protocols. Knowledge gained from this study can contribute to transformative resilience. Long-term strategic changes are necessary to improve emergency planning, such as developing a unified framework to inform a ‘Priority List’, enhancing workforce capacity, and addressing digital exclusion. These steps can strengthen health system robustness and preparedness for future crises.

Published: December 2024

Abstract
Background
Sleep is essential for cognitive function and overall well-being, yet healthcare providers often experience sleep deprivation due to long hours and night shifts. This study evaluates how sleep deprivation affects Quality of Life (QoL) and job satisfaction among these workers.

Methods
We conducted a cross-sectional study at a tertiary healthcare facility in Chengalpattu District, Tamil Nadu, India, including 293 healthcare providers working rotational night shifts. Participants were selected through stratified random sampling. QoL was assessed using the Short Form-12 QoL Questionnaire (SF-12). Sleepiness was assessed using Epworth Sleepiness Scale (EPSS). Statistical analyses included Pearson chi-square tests for associations, independent samples t-tests for comparing QoL scores between sleep-deprived and non-sleep-deprived participants, and binary logistic regression to evaluate the impact of sociodemographic factors and shift work patterns on SF-12 scores.

Results
Significant associations were observed between sociodemographic factors, shift work patterns, and SF-12 QoL scores. Married participants had nearly four times higher odds (OR = 3.97, 95%CI 1.87–8.43) of scoring < 40. Diploma holders had nearly three times higher odds (OR = 2.94, 95%CI 1.48–5.83) compared to graduates. Paramedical professionals had over three times higher odds (OR = 3.48, 95%CI 1.55–7.82) compared to doctors. Sleep deprivation was associated with lower PCS (aOR = 2.45, 95%CI 1.40–4.27) and MCS scores (aOR = 3.80, 95%CI 1.56–9.23). Increased night work hours correlated with higher odds of poor work satisfaction (OR = 1.39, 95%CI 1.18–1.63).

Conclusion
Sleep deprivation significantly impacts physical and mental QoL scores among healthcare providers working rotational night shifts. Current shift work patterns also affect QoL, highlighting the need for targeted interventions to improve sleep and manage shift work.

Published: December 2024

AbstractEndosomes are crucial sites for intracellular material sorting and transportation. Endosomal transport is a critical process involved in the selective uptake, processing, and intracellular transport of substances. The equilibrium between endocytosis and circulation mediated by the endosome-centered transport pathway plays a significant role in cell homeostasis, signal transduction, and immune response. In recent years, there have been hints linking endosomal transport abnormalities to neurodegenerative diseases, including Alzheimer's disease. Nonetheless, the related mechanisms remain unclear. Here, we provide an overview of endosomal-centered transport pathways and highlight potential physiological processes regulated by these pathways, with a particular focus on the correlation of endosomal trafficking disorders with common pathological features of neurodegenerative diseases. Additionally, we summarize potential therapeutic agents targeting endosomal trafficking for the treatment of neurodegenerative diseases.

Published: December 2024

AbstractAn efficient parallel implementation of the phase field method for quasi-brittle crack simulations able to run on supercomputers with a large number of processes is proposed. This framework uses the finite-element method on 3D structured meshes, and was developed for distributed memory machines using the Message Passing Interface (MPI) for workload distribution and data communication between processes. Parallel assembly is carried out to build the matrices associated with the linear systems of equations. In the proposed context, linear systems derived from displacement and damage discretizations are solved using parallel solvers and preconditioners from the PETSc (Portable, Extensible Toolkit for Scientific Computation) library. All additional operations in this implementation are also efficiently parallelized. Performance analysis shows linear acceleration with an efficiency of $$97\%$$

degrees of freedom can be solved in a few seconds. The methodology is applied to quasi-brittle simulations, involving alternate solving of large linear systems and incremental evolution. The applications presented to illustrate the parallel framework involve crack initiation and propagation in strongly heterogeneous materials with a detailed description of the microstructure. Large three-dimensional periodic structures and a realistic geometrical model directly obtained by micro-CT imagery are used.
New estimates and synthesis of chromosome numbers, ploidy levels and genome size variation in Allium sect. Codonoprasum: advancing our understanding of the unresolved diversification and evolution of this section
Authors: Kobrlová Lucie , Jandová Michaela , Vojtěchová Kateřina , Šafářová Lenka , Duchoslav Martin 
Published: December 2024

Abstract
Background
The genus Allium is known for its high chromosomal variability, but most chromosome counts are based on a few individuals and genome size (GS) reports are limited in certain taxonomic groups. This is evident in the Allium sect. Codonoprasum, a species-rich (> 150 species) and taxonomically complex section with weak morphological differences between taxa, the presence of polyploidy and frequent misidentification of taxa. Consequently, a significant proportion of older karyological reports may be unreliable and GS data are lacking for the majority of species within the section. This study, using chromosome counting and flow cytometry (FCM), provides the first comprehensive and detailed insight into variation in chromosome number, polyploid frequency and distribution, and GS in section members, marking a step towards understanding the unresolved diversification and evolution of this group.

Results
We analysed 1578 individuals from 316 populations of 25 taxa and reported DNA ploidy levels and their GS, with calibration from chromosome counts in 22 taxa. Five taxa had multiple ploidy levels. First estimates of GS were obtained for 16 taxa. A comprehensive review of chromosome number and DNA-ploidy levels in 129 taxa of the section revealed that all taxa have x = 8, except A. rupestre with two polyploid series (x = 8, descending dysploidy x = 7), unique for this section. Diploid taxa dominated (72.1%), while di- & polyploid (12.4%) and exclusively polyploid (15.5%) taxa were less common. Ploidy diversity showed that diploid taxa dominated in the eastern Mediterranean and decreased towards the west and north, whereas only polyploid cytotypes of di- & polyploid taxa or exclusively polyploid taxa dominated in northern and northwestern Europe. A 4.1-fold variation in GS was observed across 33 taxa analysed so far (2C = 22.3–92.1 pg), mainly due to polyploidy, with GS downsizing observed in taxa with multiple ploidy levels. Intra-sectional GS variation suggests evolutionary relationships, and intraspecific GS variation within some taxa may indicate taxonomic heterogeneity and/or historical migration patterns.

Conclusions
Our study showed advantages of FCM as an effective tool for detecting ploidy levels and determining GS within the section. GS could be an additional character in understanding evolution and phylogenetic relationships within the section.

AbstractThis study addresses the issue of insufficient physical activity (PA) among youths. The emergence of gamified interventions, such as Gamifiter web portal, offers a novel approach to promoting healthy habits and increasing intrinsic motivation for PA. Gamifiter engages users in virtual challenges linked to daily step counts and progress on a digital map, aiming to enhance PA and physical literacy. Involving 107 pupils (12–13 years old), the intervention utilized Garmin VívoFit trackers, with the Gamifiter portal providing individual PA reports, challenges, and interactive educational applications. Results showed a significant increase in daily step counts indicating the positive impact of Gamifiter on PA levels. Attitudes Towards Educational Reality questionnaire and incomplete sentence test results revealed pupils' positive perceptions, high motivation, and satisfaction with Gamifiter. Teachers also praised Gamifiter for promoting PA and literacy, although some desired more customization options. The study emphasizes the potential of gamified interventions to effectively promote a healthy lifestyle. Positive attitudes and increased PA suggest that gamification can be a valuable tool in motivating and engaging pupils in physical activities, fostering a foundation for a healthier lifestyle. In conclusion, Gamifiter's success in motivating pupils to engage in higher levels of PA highlights its potential as a useful tool for promoting a healthy lifestyle. Future studies with larger sample sizes and longer follow-up periods are recommended to better understand the sustained impact of gamified interventions on health among youths.
Unintended effects of herbicide exposure on non-target beetle Zygogramma bicolorata Pallister, 1953, a bio-control agent of Parthenium hysterophorus weed
Authors: Singh Neha , Maheshwari Nikhil , Qamar Ayesha 
Published: December 2024

Abstract
Background
Herbicides are commonly used to safeguard crops against weed damage, but their effects on non-target organisms like Zygogramma bicolorata, a natural bio-control agent feeding on Parthenium hysterophorus, an invasive weed, have raised concerns. This study investigates the impact of pendimethalin, a widely used herbicide, on Z. bicolorata.

Results
The results of the present study reveal adverse effects induced by pendimethalin on various life parameters of Z. bicolorata. Fecundity decreased by approximately 20.98%, while egg viability reduced by about 18.36%. Female lifespan decreased by approximately 11.18%, and male lifespan decreased by about 13.80%, with an associated increase in developmental time period. Oviposition days after pendimethalin treatment showed only a minor 9.18% decrease compared to the control group. Pendimethalin also negatively impacted the gut antioxidants of Z. bicolorata, resulting in oxidative stress that can harm gut health and disrupt biological processes. At the molecular level, it has also been observed the DNA damage in the midgut tissue of Z. bicolorata.

Conclusion
This study underscores the unintended consequences of herbicide use on non-target organisms, emphasizing the potential threats to biodiversity. Evaluating chemical impacts on non-target organisms is crucial for ensuring responsible and sustainable chemical use in agriculture and other sectors.
