Scholars' engagement with digital social networks is complex, warranting a comprehensive understanding of their use and participation. Current research has not yet grasped the motivators, gratification, and challenges that academics encounter across multiple digital social networks. With this in mind, this study surveyed scholars who purposely participate in digital social networks for professional endeavors. The theoretical frameworks guiding this research are the Uses and Gratification framework and the networked participatory scholarship conceptualization. A total of 307 higher education scholars completed an electronic survey with closed and open-ended questions. Data analysis included descriptive statistics and a team-coding approach for qualitative data. The results of this investigation highlight specific motivators for using digital social networks to support the scholar's teaching, research, and professional development. The results of this investigation suggest that scholars are constantly navigating challenges and trading them off against the benefits. The results of this investigation also helped determine the imagined audiences that scholars perceive as potential spectators when using digital social networks for their scholarly efforts. The results illustrate the many reasons provided by scholars, which aligned with the self-presentation and impression management theory.

This study addresses the growing interest in transformative experiences in international academic tourism from a managerial and consumer perspective. While the managerial perspective focuses on delivering highly personalized experiences that profoundly impact each individual, the consumer perspective emphasizes inner transformation and personal growth. Despite recent developments in understanding transformative experiences, comprehensive empirical studies encompassing both consumer and managerial perspectives, as well as focusing on academic tourism remain limited. To fill this gap, the research conducted in-depth semi-structured interviews with international academic tourists, integrating both managerial and consumer perspectives. The study confirmed previously identified dimensions of transformative experiences and unveiled a novel facet related to intended achievements. Additionally, the findings corroborated that academic tourists undergo transformative experiences during their study abroad programs. This research contributes valuable insights to academia and the tourism industry, shedding light on the multifaceted nature of transformative experiences in the context of international academic tourism.

Relief mapping through dense tropical forest is a challenge, which can be met by processing radar images. Various global digital elevation models (DEMs) are available, either free or paid, the most widely used methods for producing them at global scale being photogrammetry and short wavelength radar interferometry. However, the resulting DEMs do not directly represent the ground surface but rather the canopy or something in between. Since most users need terrain models for a variety of applications in geoscience, water management etc. but use such canopy models for lack of anything better, it was relevant to assess the consequences of this inappropriate but unavoidable choice. This paper presents a study carried out in the Brazilian Amazon, where an airborne P-band radar interferometric DEM was used as a reference based on its accuracy assessed in previous studies. A well-established DEM (SRTM) and newer ones (Copernicus and Fabdem), as well as a DEM obtained from aerial X-bands radar data, were compared to the reference according to different criteria related to elevation (accuracy and a typical application, i.e., dam filling simulation) and to slope at different scales (accuracy and a typical application, i.e., terrain classification). The results highlighted the risks of using short wavelengths to represent the terrain and emphasized the importance of slope in different resolution scales.

Atherosclerotic cardiovascular disease (ASCVD) remains the major cause of premature death and disability; effective cardiovascular (CV) risk prevention is fundamental. The World Heart Federation (WHF) Cholesterol Roadmap provides a framework for national policy development and aims to achieve ASCVD prevention.At the invitation of the WHF, a group of experts from the Portuguese Society of Cardiology (SPC), addressed the cholesterol burden at nationally and discussed possible strategies to include in a Portuguese cholesterol roadmap. The literature review showed that the cholesterol burden in Portugal is high and especially uncontrolled in those with the highest CV risk. An infographic scorecard was built to include in the WHF collection, for a clear idea about CV risk and cholesterol burden in Portugal, which would also be useful for health policy advocacy.The expert discussion and preventive strategies proposal followed the five pillars of the WHF document: awareness improvement; population-based approaches for CV risk and cholesterol; risk assessment/population screening; system-level approaches; surveillance of cholesterol and ASCVD outcomes. These strategies were debated by all the expert participants, with the goal of creating a national cholesterol roadmap to be used for advocacy and as a guide for CV prevention.Several key recommendations were outlined: include all stakeholders in a multidisciplinary national program; create a structured activities plan to increase awareness in the population; improve the quality of continuous CV health education; increase the interaction between different health professionals and non-health professionals; increment the referral of patients to cardiac rehabilitation; screen cholesterol levels in the general population, especially high-risk groups; promote patient self-care, engage with patients’ associations; use specific social networks to spread information widely; create a national database of cholesterol levels with systematic registry of CV events; redefine strategies based on the evaluation of results; create and involve more patients’ associations – invert the pyramid order.In conclusion, ASCVD and the cholesterol burden remain a strong global issue in Portugal, requiring the involvement of multiple stakeholders in prevention. The Portuguese cholesterol roadmap can provide some solutions to help urgently mitigate the problem. Population-based approaches to improve awareness and CV risk assessment and surveillance of cholesterol and ASCVD outcomes are key factors in this change. A call to action is clearly needed to fight hypercholesterolemia and ASCVD burden. Resumo: A doença aterosclerótica cardiovascular (DACV) mantém-se a maior causa de morte prematura e de incapacidade, sendo uma prevenção eficaz de risco cardiovascular (CV) fundamental. O WHF Cholesterol Roadmap fornece enquadramento para o desenvolvimento de políticas nacionais, tendo como objetivo a prevenção de DACV. A convite da WHF, um grupo de peritos da Sociedade Portuguesa de Cardiologia (SPC) avaliou a carga do colesterol a nível nacional e discutiu possíveis estratégias para um Roadmap português.A revisão da literatura mostrou uma carga elevada de colesterol em Portugal, sobretudo em pessoas de alto risco CV. Uma infografia, Scorecard, foi construída pela WHF, para mostrar claramente o risco CV e o peso do colesterol em Portugal, sendo útil para advocacia em políticas de saúde.A discussão de peritos e proposta das estratégias preventivas seguiram os cinco pilares do documento da WHF: Melhoria da consciencialização; Abordagens do risco CV e do colesterol nas populações; Avaliação de risco/screening das populações; abordagens a nível do sistema; Seguimento do colesterol e complicações da DACV.Várias recomendações chave foram definidas: incluir todos os stakeholders em programa multidisciplinar nacional; criar plano de atividades estruturadas para aumentar a consciencialização da população; aumentar qualidade da educação contínua em saúde CV; aumentar interação entre profissionais de saúde e outros profissionais; aumentar referenciação de doentes para reabilitação cardiovascular; avaliar níveis de colesterol na população geral, especialmente em alto risco; promover autocuidado dos doentes, envolvendo associações de doentes; usar redes sociais específicas para disseminar informação; criar base nacional de níveis de colesterol com registo sistemático de eventos CV; redefinir estratégias baseadas na avaliação de resultados; criar e envolver mais doentes em associações – inverter a ordem da pirâmide!Em conclusão, a DACV e o peso de colesterol permanecem uma questão global forte em Portugal, necessitando o envolvimento de múltiplos stakeholders na prevenção. O Roadmap de colesterol português pode fornecer algumas soluções para urgentemente mitigar o problema. Abordagens a nível das populações para melhorar a consciencialização e avaliar o risco CV, seguimento do colesterol e das complicações de DACV são fatores chave nesta mudança. Uma call to action é claramente necessária para combater a carga da hipercolesterolemia e DACV.

Abstract Mine waste can be transformed into technosol as an ecological strategy. Despite its importance to soil functions, biological activity is often overlooked. Biopolymers can serve as innovative tools for bioremediation, facilitating chemical reactions and creating networks to encapsulate contaminants. This work aims to assess the use of bioleached and stabilised residues from a tungsten mine for technosol production. The first objective was to evaluate mine tailings for their bioleaching potential by biostimulation or bioaugmentation with strain Diaphorobacter polyhydroxybutyrativorans B2A2W2. The second was to evaluate the effect of Portland cement or biopolymers such as Carboxymethyl Cellulose (CMC) or Xanthan Gum (XG) on the stabilisation of bioleached residues. The impact of biopolymers on residues’ characteristics, such as metal leaching, number of cultivable microorganisms, compression strength and ecotoxicity was evaluated using flow systems. Over time, bioleached metallic elements decreased, except for iron (Fe). Biostimulated and stabilised residues exhibited similar trends; both CMC and cement showed low leaching rates and viable microorganisms in the same order (106 CFU × ml−1). However, bioaugmented residue stabilised with XG showed 106 CFU × ml−1 viable microorganisms and increased 2.2-fold Fe leaching than BA_Control. CMC addition to bioaugmented residue reduced 5.9-fold Fe leaching and increased 100-fold viable microorganisms. By utilising both biological and engineering approaches to characterise the technosol, this study contributes to advancing knowledge of technosol production. The residues biostimulated and stabilised with CMC produced a material useful for bio-applications, with low toxicity and metal leaching, useful for bio-applications. XG was the best stabiliser for geotechnical engineering applications, with improved compression strength. In conclusion, the study demonstrates the usefulness of biopolymer treatment for residues and emphasises the importance of selecting the appropriate biopolymer for the intended function of technosols.

Abstract This data descriptor presents a curated dataset for pathogen detection and identification (Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans) directly from whole-blood samples. The dataset was created using differential cell lysis combined with rapid extraction, digestion, and mass spectrometry-based proteomics. Our method offers a rapid diagnostic alternative to traditional culture, enabling timely disease management, such as sepsis. Highlighting our dataset’s uniqueness, it features a three-tier structure: Spectral Libraries of Pathogens for identifying peptide peaks for putative biomarkers; Spiked pathogen in blood MS data for biomarker panel optimization through varied concentration samples; and Parallel Reaction Monitoring (PRM) data from sepsis patients for validating our biomarker panel, achieving 83.3% sensitivity within seven hours without microbial enrichment culture. This dataset serves as a comprehensive reference for bioinformatic tool development and biomarker panel proposals, advancing microbial detection, antimicrobial resistance, and epidemiological studies.

Introduction: A pelvic abscess is a potential life-threatening condition that should be managed conservatively whenever possible. Currently, computed tomography or ultrasound-guided percutaneous drainage is still the gold standard approach for pelvic fluid collections (PFCs) requiring intervention. More recently, endoscopic ultrasound (EUS) drainage using lumen-apposing metal stents (LAMSs) has been used off-label in PFCs with similar efficacy, a favorable safety profile, better quality of life, and generally a shorter duration of treatment when compared to the gold standard treatment. Methods: An observational retrospective analysis of 6 patients who underwent EUS-guided PFC drainage with LAMS at our institution was conducted. Records were reviewed to identify etiology, size of the collection, number of endoscopic procedures required until complete resolution, stent indwelling time, concomitant surgical or percutaneous associated procedures, successful removal and resolution. Results: The 6 patients included had an average age of 69 years old and 5 (83.3%) were male. The average size of the PFCs was 72.5 mm. All patients (100%) had successful drainage following LAMS placement, though 1 patient had an early recurrence. The mean stent indwelling time in our study was 6.7 days. An additional percutaneous or surgical drainage intervention was not required in any of the participants. Also, no adverse events related to the procedure were reported during the follow-up period. Conclusion: EUS-guided drainage of PFCs with LAMS is a safe and minimally invasive technique, which allows rapid PFC resolution, with no need for percutaneous or surgical drainage interventions.

INTRODUCTION: Little is known about management and mitigation of COVID-19 in long-term care facilities (LTCF) for older adults in Latin America. OBJECTIVE: To describe how the management of LTCF in Hispanic American countries plan and adapt their routines for coping with COVID-19 and whether they have been able to fulfill recommendations published by the World Health Organization (WHO). METHODOLOGY: A cross-sectional study was conducted by online survey of managers of LTCF located in Hispanic American countries. A 46-item questionnaire (adopting the WHO principles) was sent to participants. Descriptive statistics were used to summarize the data. RESULTS: Twenty-three care home managers replied, responsible for a total of 874 older people (range: 5 - 270). One questionnaire was excluded because of missing responses. Fourteen LTCF (63.60%) were private, for-profit facilities. The rate of compliance with WHO recommendations exceeded 70% for the majority of items. Just over half of the institutions had developed a strategic management plan, or had identified strategies for dealing with deaths of suspected cases. Difficulty acquiring personal protective equipment (PPE) was reported by 59.10% of the LTCF surveyed. The homes' capacity for SARS-Cov-2 testing was limited (36.36% of the institutions did not have any tests). CONCLUSIONS: The rate of compliance with recommendations published by the WHO for dealing with COVID-19 was greater than 70% at the majority of the LTCF surveyed. More than half of the institutions had strategic management plans. Availability of PPE and SARS-Cov-2 testing capacity were very unsatisfactory.

Abstract Exploring molecular biomarkers in lava tube speleothems offers insights into environmental dynamics, biogeochemical processes, and subsurface life, with implications for astrobiology, particularly in Martian analog environments. Despite extensive biomarker research in marine and terrestrial settings, lava tube studies are limited. This study employed molecular, isotope and mineralogical characterization to analyze sulfate speleothems from six lava tubes of Lanzarote (Canary Islands), considered analog for the Moon and Mars. The combination of mass spectrometry, thermogravimetry, and mineralogical techniques, revealed geological processes, biomarkers and their biological sources. The identified minerals were primarily calcium and sodium sulfates. Sulfur isotope analyses indicated volcanic and oceanic origins, while carbon isotope composition and pyrolysis analyses suggested influences from vegetation and microbial activity. Lipidic profiles highlighted branched and n-alkanes, as well as palmitic and stearic acid methyl esters, suggesting microbial origins. These findings contribute to understanding geological and environmental dynamics in lava tubes and recognizing potential biosignatures on Earth and other planets.

Abstract Background African mahogany species (Khaya sp.) have been introduced to Brazil gaining increasing economic interest over the last years, as they produce high quality wood for industrial applications. To this date, however, the knowledge available on the genetic basis of African mahogany plantations in Brazil is limited, which has driven this study to examine the extent of genetic diversity and structure of three cultivated species (Khaya grandifoliola, Khaya senegalensis and Khaya ivorensis) and their prospects for forest breeding. Results In total, 115 individuals were genotyped (48 of K. grandifoliola, 34 of K. senegalensis and 33 of K. ivorensis) for 3,330 filtered neutral loci obtained from genotyping-by-sequencing for the three species. The number of SNPs varied from 2,951 in K. ivorensis to 4,754 in K. senegalensis. Multiloci clustering, principal component analysis, Bayesian structure and network analyses showed a clear genetic separation among the three species. Structure analysis also showed internal structure within each species, highlighting genetic subgroups that could be sampled for selecting distinct genotypes for further breeding, although the genetic distances are moderate to low. Conclusion In our study, SNP markers efficiently assessed the genomic diversity of African mahogany forest plantations in Brazil. Our genetic data clearly separated the three Khaya species. Moreover, pairwise estimates of genetic distances among individuals within each species showed considerable genetic divergence among individuals. By genotyping 115 pre-selected individuals with desirable growth traits, allowed us not only to recommend superior genotypes but also to identify genetically distinct individuals for use in breeding crosses.

Abstract Introduction People with human papiloma virus (HPV) struggle with numerous challenges and needs in physical, and psychological aspects of quality of life related to this virus. Several studies have recommended counseling interventions to improve the quality of life for these individuals. There is also a need for standardized and normalized instruments in Iran to evaluate the effect of educational and therapeutic interventions on the quality of life of these patients. Therefore, this study was conducted in gynecological cancer clinics in Kerman and Mashhad to investigate the psychometric properties of the Persian version of the “Quality of Life Questionnaire for Women Infected with HPV”. Methods This study cross-sectional study included 580 women infected with HPV referred to Kerman and Mashhad’s gynecologic cancer clinics. The samples were selected using convenience sampling method in 2023. Content validity, face validity, and construct validity were assessed using explanatory factor analysis (EFA) and confirmatory factor analysis (CFA). Results The results of the content validity assessment, which included the Content Validity Index (CVI) and the Content Validity Ratio (CVR), indicated strong content validity. Additionally, qualitatively confirmed face validity, further supports these findings. The results of the EFA revealed that the Persian version of the EQUALI-HPV questionnaire has a 6-factor structure, with 34 items remaining from the 54 items. These 6 factors accounted for 48.9% of the variance and were confirmed by confirmatory factor analysis and using robust root mean square error of approximation (RMSEA = 0.054), comparative fit index (CFI = 0.928), and Tucker-Lewis index (TLI = 0.920). The content validity results showed that all the items had a good validity ratio and index. Cronbach’s alpha and Raykov’s rho were greater than 0.7 for all dimensions. Conclusion The results showed that the Persian version of the “Quality of Life Questionnaire for Women Infected with HPV” had acceptable validity and reliability and can be utilized to measure the quality of life of these people and conduct psychological studies.

Abstract Permanent artificial lighting systems in tourist underground environments promote the proliferation of photoautotrophic biofilms, commonly referred to as lampenflora, on damp rock and sediment surfaces. These green-colored biofilms play a key role in the alteration of native community biodiversity and the irreversible deterioration of colonized substrates. Comprehensive chemical or physical treatments to sustainably remove and control lampenflora are still lacking. This study employs an integrated approach to explore the biodiversity, eco-physiology and molecular composition of lampenflora from the Pertosa-Auletta Cave, in Italy. Reflectance analysis showed that photoautotrophic biofilms are able to absorb the totality of the visible spectrum, reflecting only the near-infrared light. This phenomenon results from the production of secondary pigments and the adaptability of these organisms to different metabolic regimes. The biofilm structure mainly comprises filamentous organisms intertwined with the underlying mineral layer, which promote structural alterations of the rock layer due to the biochemical attack of both prokaryotes (mostly represented by Brasilonema angustatum) and eukaryotes (Ephemerum spinulosum and Pseudostichococcus monallantoides), composing the community. Regardless of the corrosion processes, secondary CaCO3 minerals are also found in the biological matrix, which are probably biologically mediated. These findings provide valuable information for the sustainable control of lampenflora.
