Abstract
A rapid development strategy was successfully implemented to create a suEPSR111459pramolecular metallogel comprising Mn(II) (referred to as MnA-TA) and Zn(II) (referred to as ZnA-TA) ions. These gels were formed using L-(+)-tartaric acid as a low molecular weight gelator in DMF medium at ambient conditions. Rheological analysis was employed to assess the mechanical stability of the synthesized MnA-TA and ZnA-TA metallogel. The results of the analysis revealed the gel’s impressive resilience when subjected to various angular frequencies and levels of oscillator stress. The exploration of MnA-TA and ZnA-TA metallogel’s distinct morphological patterns was conducted using FESEM images. FESEM analysis revealed that MnA-TA metallogel exhibited a flake-like hierarchical network structure, while ZnA-TA metallogel demonstrated a diamond-shaped architecture. EDX analysis was utilized for elemental mapping, confirming the presence of primary chemical constituents in the metallogels. The formation strategy and nature of the gel materials were examined through FT-IR spectroscopy and PXRD analysis. The synthesized metallogels exhibited semiconducting properties, as confirmed by optical band-gap measurements. Furthermore, a metal-semiconductor junction-based device was successfully fabricated by combining Al metal with Mn(II)- and Zn(II)-metallogels. The device displayed nonlinear charge transport behavior, resembling that of a Schottky diode, as evidenced by its I-V characteristic. This indicates the potential use of the sandwich-like configuration of ITO/MnA-TA metallogel/Al and ITO/ZnA-TA metallogel/Al in the development of advanced electronic devices based on supramolecular Mn(II)- and Zn(II)-metallogels. Notably, the direct utilization of tartaric acid and Mn(II)/Zn(II) sources in the MnA-TA and ZnA-TA metallogels presents an innovative approach, highlighting their suitability as semiconducting materials for device fabrication. This study delves into the multifunctional applications of MnA-TA and ZnA-TA metallogels, providing valuable insights for researchers in the field of material science.

Abstract

Purpose
To assess the relationship between quality of life (QoL) and ocular surface health within a Finnish population-based cohort.

Methods
A cross-sectional study involved 601 individuals born between the years 1933–1956. Ocular surface health and dry eye disease (DED) were clinically evaluated using several diagnostic tests. Participants completed the Ocular Surface Disease Index (OSDI), QoL assessment with the 15D and Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), and the Beck’s Depression Inventory (BDI-II) questionnaires. Various statistical methods were employed to explore the associations between QoL, ocular surface health, and sex disparities.

Results
DED had negative impact on QoL in all participants, and especially in women. Adjusted for comorbidities, DED doubled the odds of worse health-related QoL (15D: OR = 2.31 [95% CI: 1.24–4.31, p < 0.01]) and mental health (SF-36 MCS and BDI-II: OR = 2.08 [95% CI: 1.04–4.16, p < 0.05]). Noninvasive tear break-up time (NIBUT) correlated with all QoL scores. In women, the most significant clinical signs correlating with low QoL were NIBUT (15D: r = 0.20, p = 0.002; SF-36 MCS: r = 0.18, p = 0.026), and conjunctival staining (15D: r=-0.19, p = 0.004; BDI-II: r = 0.27, p < 0.001), whereas in men, blepharitis correlated with depression score (BDI-II: r = 0.20, p = 0.036). High OSDI was associated with worse QoL in women, but not in men.

Conclusion
This first population-based study assessing general QoL data with objective clinical measures of DED indicated that among elderly population, both symptoms and signs of DED independently impacted different aspects of QoL. In addition, significant sex-differences in these associations were observed and should be considered both in research settings and when assessing and treating people with DED.

Abstract
Skates and rays (Batoidea) play a significant ecological role, contributing to ecosystem services through bioturbation and acting as vital intermediate components of the trophic chain in various aquatic environments. Despite their wide global distribution and ecological importance, batoids receive less attention than their shark relatives, resulting in substantial knowledge gaps that might impede a comprehensive understanding of their conservation status. This review addresses critical aspects of their capture, handling, tagging, and release to provide readers with crucial information needed to perform research on batoids. Protocols for analgesia, anaesthesia, and euthanasia are also discussed, taking into account the ethical and logistical considerations necessary for research involving this group of species. This information can give researchers and ethics committees the knowledge to conduct and approve studies involving batoids, thereby promoting more effective and ethical research practices.
Attitudes towards healthy eating and its determinants among older adults in a deprived region of Hungary: implications for the National Healthy Aging Program

Published: January 2025

Abstract
A healthy diet is a key determinant of successful aging. However, the psychological, social, and physiological changes associated with ageing often disrupt dietary behaviours. Hungary has one of the highest rates of chronic age-related diseases in the European Union, exacerbated by unhealthy dietary patterns and rapid population aging. This study evaluates attitudes and barriers to healthy eating among older adults in a socioeconomically disadvantaged region of Hungary, identifying determinants of these attitudes across different age groups. A cross-sectional survey sampled 678 adults aged 18 and older from Northeast Hungary, assessing their beliefs on healthy eating through an attitude score (range: 9–45). Multivariate regression analyses were conducted to explore relationships between mental health, self-perceived health, and attitudes toward healthy eating. The mean attitude score was 31.47 (± 5.14), with older adults (≥ 65 years) showing significantly greater uncertainty about dietary choices. The cost of healthy food was the most frequently reported barrier, regardless of age. Regression results revealed that older adults with higher well-being (B = 0.03, p = 0.026), life satisfaction (B = 0.40, p = 0.005), and self-perceived health (fair: B = 2.20, p = 0.003; good/very good: B = 1.96, p = 0.031) were more likely to have positive attitudes toward healthy eating. These results emphasize the importance of addressing both mental and physical health in educational interventions to promote healthier diets. Tailored approaches addressing affordability and accessibility of healthy foods are critical to advancing Hungary’s National Healthy Aging Program and mitigating dietary risk factors among vulnerable populations.

Published: January 2025

Abstract
Finite element analysis has become indispensable for biomechanical research on clavicle fractures. This review summarized evidence regarding configurations and applications of finite element analysis in clavicle fracture fixation. Seventeen articles involving 22 clavicles were synthesized from CINAHL, Embase, IEEE Xplore, PubMed, Scopus, and Web of Science databases. Most studies investigated midshaft transverse closed fractures by reconstructing intact models from CT scans and simulating fractures through gap creation. Common loading schemes included axial compression, distal torsion, and inferior bending. The primary objective was comparing different implant designs/placements on construct stiffness, von Mises stress, and fracture site micro-motion. Our review suggested a preference for plate fixation, particularly with anterior placement, for midshaft transverse fractures. However, limited fracture types studied constrain comprehensive recommendations. Additionally, the review highlighted discrepancies between finite element and clinical studies, emphasizing the need for improved modeling of physiological conditions. Future research should focus on developing a comprehensive database of finite element models to test various implant options and placements under common loading schemes, bridging the gap between biomechanical simulations and clinical outcomes.

Short on time—big on impact: MeetingHacks as a digital intervention to enhance virtual meeting collaboration
Authors: Tartler Darien , Ritter Marie , Kauffeld Simone 
Published: January 2025

Abstract
This contribution to the journal ‘Gruppe. Interaktion. Organisation. (GIO)’ presents a novel video learning format for optimizing virtual meetings as well as initial evaluation data on its usefulness and application in an organizational context: the MeetingHacks. Effective collaboration in virtual meetings requires a novel approach to fusing communication and technology. To enhance virtual meetings through accessible digital interventions, we developed MeetingHacks, a series of short videos based on findings of contemporary meeting science. These MeetingHacks address general aspects as well as professional, methodological, social, and proactive aspects of meeting behavior, aligning with the four facets of team skills of the Kassler competence grid. The introductory video, Meetings General, triggers reflective processes to enhance the impact of the subsequent MeetingHacks. Meetings Professional focuses on professional skills, particularly the interplay of problems and solutions and knowledge transfer, drawing on results from interaction analysis and shared mental models. Meetings Structured addresses methodological behavior, emphasizing structured meeting designs. Meetings Social covers prosocial behavior, focusing on making social and informal interaction in virtual meetings more tangible. Meetings Proactive highlights responsibility and proactivity in meetings, informed by interaction analysis and reflection research. The MeetingHacks were implemented over five weeks in a corporate setting and evaluated for their usefulness, applicability, and fit within daily routines. The results demonstrated the benefits and limits of MeetingHacks in an organizational context. Based on this evaluation, this article critically discusses the merits and further development of the MeetingHacks and their effectiveness as a digital intervention.

Published: January 2025

Abstract
This work discusses the relevance of direct energy deposition (DED) and its classifications. Different types of DED processes are discussed, including their main parameters and issues. Two experiments were carried out, named single bead and rectangular prism, for the purpose of this research. These were built with a hot wire and laser DED system, where experimental thermal data were obtained, later geometric information was obtained via a 3D scan. Limitations of the equipment used as well as observed defects in the material deposition are discussed based on the experimental data. FEA models were developed to duplicate the experiments, which included a detailed geometry of the single bead. Two modifications to the bead geometry are presented and evaluated, where it is was concluded that a semi-circular bead approximation provides better results than if a rectangular one is assumed. This led to the definition of a thermal and structural equivalent model of the single bead, which was the basis for the numerical work of the rectangular prism. The results obtained for the latter show good agreement with the thermal results, although differences in the structural results are perceptible.

Abstract

Purpose
Malaria remains a major global health challenge, particularly in sub-Saharan Africa and low- and middle-income countries (LMICs), contributing substantially to mortality and morbidity rates. In resource-limited settings, access to specialized diagnostic tests is often restricted, making basic blood analysis a valuable diagnostic tool. This study investigated the correlation between malaria infection and full blood count values in a rural region of Ghana during the 2022 rainy season, aiming to highlight diagnostic insights available from routine blood analyses.

Methods
A retrospective case-control analysis was conducted on 544 confirmed malaria cases, comparing their blood values with those of matched malaria-negative controls.

Results
Parasitaemia levels peaked during the rainy season, with July showing the highest values. Malaria-positive patients exhibited lower levels of haemoglobin, white blood cells, lymphocytes, and platelets, but higher neutrophil counts compared to controls. Middle-aged women had significantly lower haemoglobin levels than men, and younger individuals showed higher parasitaemia levels. A negative correlation was found between Plasmodium density and haemoglobin and platelet counts, while positive correlations were observed with white blood cell and neutrophil counts.

Conclusion
This study highlights the significant burden of malaria in rural Ghana during the rainy season and underscores the impact of infection on blood values. Routine full blood count analysis provides a practical and accessible diagnostic tool in resource-limited settings. The findings emphasise the importance of targeted interventions for high-risk groups, particularly children and women, to improve patient management and reduce malaria-related morbidity.

Published: January 2025

Abstract

Background
Bariatric surgery is the most long-term effective treatment option for severe obesity. The role of gut microbiome (GM) in either the development of obesity or in response to obesity management strategies has been a matter of debate. This study aims to compare the impact of two of the most popular procedures, sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (GB), on metabolic syndrome parameters and gut bacterial microbiome and in systemic immuno-inflammatory response.

Methods
A prospective observational study enrolled 24 patients with severe obesity, 14 underwent SG and 10 GB. Evaluations before (0 M) and 6 months (6 M) after surgical procedures included clinical and biochemical parameters, expression of 17 immuno-inflammatory genes in peripheral blood leukocytes, and assessment of gut microbiome profile using 16 s rRNA next-generation sequencing approach. Statistical significance was set to a p value < 0.05 with an FDR < 0.1.

Results
A significant and similar decrease in weight-associated parameters and for most metabolic markers was achieved with both surgeries. Considering the gut microbiome in the whole study population, there was an increase in alpha diversity at family-level taxa. Beta diversity between SG and GB at 6 M showed near significant differences (p = 0.042) at genus levels. Analysis of the relative abundance of individual taxonomic groups highlighted differences between pre- and post-surgical treatment and between both approaches, namely, a higher representation of family Enterobacteriaceae and genera Veillonella and Enterobacteriaceae_unclassified after GB. Increased expression of immune-inflammatory genes was observed mainly for SG patients.

Conclusions
We conclude that SG and GB have similar clinical and metabolic outcomes but different impacts in the gut bacterial microbiome. Results also suggest reactivation of immune response after bariatric surgery.
Variation in weed seed DNA detectability among arable carabids with different trophic specialization
Authors: Neidel Veronika , Vašková Hana , Wallinger Corinna , Saska Pavel 
Published: January 2025

Abstract
While most ground beetles (Coleoptera: Carabidae) include seeds in their diet, preferences for seed feeding vary among carabid species and range from facultative diet supplementation to obligate seed feeding. DNA-based diet analyses have been used to study their regulatory effect on soil seedbanks. It is unknown whether specialized granivores digest seed species they are adapted to (‘essential seeds’) faster, and whether this affects food web construction based on molecular data. We hypothesized that specialized granivores digest their essential seed faster than other seeds, and at faster rates than generalist granivores or carnivores. Further, we assumed that generalist granivores digest different seeds equally fast, while carnivorous carabids digest seeds slower than granivores. In feeding experiments, three carabid species—Amara similata (specialized granivore), Harpalus affinis (generalist granivore), and Poecilus cupreus (generalist carnivore)—were fed either a broadly accepted seed or the specialist's essential seed. Gut content samples were collected 0, 6, 12, 24, 48, and 72 h after feeding and screened with plant-primers to trace seed DNA. Time until 50% detection probability in the specialists was shorter for its essential than the broadly accepted seed and shorter than in the generalist granivore, which digested both seed species equally fast. The carnivore was reluctant to feed on the seed species offered, and detection probabilities did not significantly decrease with digestion time. Our findings suggest that the strength of specialized granivores’ feeding interactions and their role in weed seed regulation might be underestimated when assessed with DNA-based diet analysis, due to their more efficient seed digestion.
Head and Neck Classic Hodgkin, T and NK Lymphomas with Eosinophilia
Authors: Danielson David T , Aguilera Nadine S , Auerbach Aaron 
Published: January 2025

Abstract
Eosinophilia is a notable feature in various hematological malignancies, including specific types of leukemias and lymphomas that may occur in the head and neck. In hematologic malignancies, eosinophilia can be primary, driven by genetic abnormalities, or secondary, resulting from cytokine and chemokine production by the neoplastic cells or the tumor microenvironment. This review examines the association between eosinophilia and head and neck hematolymphoid malignancies including Classic Hodgkin lymphoma, T-cell lymphoblastic leukemia, mature T and NK-cell lymphomas, and Langerhans cell histiocytosis. It explores the underlying mechanisms of eosinophilia in these malignancies, highlighting the role of chemokines and cytokines such as IL-5, TARC, and eotaxin. Recognition of eosinophilia may aid in the diagnosis of these conditions and understanding the mechanisms of eosinophilia may provide insights into potential prognostic implications and treatment strategies.

Abstract
HIV-prevention efforts focusing on women of child-bearing potential are needed to end the HIV epidemic in the African region. The use of antiretroviral drugs as pre-exposure prophylaxis (PrEP) is a critical HIV prevention tool. However, safety data on new antiretrovirals during pregnancy are often limited because pregnant people are excluded from drug development studies. Calls from communities, healthcare professionals, and regulators to improve the information supporting decision-making around the use of medical products during pregnancy have been increasing. Post-marketing safety surveillance is an essential tool for detecting adverse outcomes and evaluating real-world, longer-term effects of drugs. Detecting and evaluating uncommon pregnancy outcomes requires large sample sizes, highlighting the benefits of and need for safety surveillance. Surveillance systems vary widely across Africa, and the need for enhanced surveillance of PrEP use during pregnancy highlights the limitations of current regulatory and surveillance systems. Challenges include weak regulation and insufficient resources. Pooling of resources and regulatory harmonization could address resource challenges. The African Medicines Agency, as a specialized agency of the African Union, has the potential to improve African medical product regulation, including post-marketing safety surveillance. This can strengthen regulation and ensure that market authorization holders meet their responsibility to invest in post-marketing surveillance systems, such as pregnancy registries. At the same time, independent post-marketing studies are needed to ensure generation of essential safety data. The Forum for Collaborative Research has initiated a project to facilitate interactions between regulators in Africa, the USA, and Europe, as well as other stakeholders, and to work toward consensus on safety data generation from PrEP during pregnancy before and after marketing authorization.
