Percutaneous coronary intervention for bifurcation coronary lesions using optimised angiographic guidance: the 18th consensus document from the European Bifurcation Club.

The 2023 European Bifurcation Club (EBC) meeting took place in Warsaw in October, and the latest evidence for the use of intravascular ultrasound (IVUS) and optical coherence tomography (OCT) to optimise percutaneous coronary interventions (PCI) on coronary bifurcation lesions (CBLs) was a major focus. The topic generated deep discussions and general appraisal on the potential benefits of IVUS and OCT in PCI procedures. Nevertheless, despite an increasing recognition of IVUS and OCT capabilities and their recognised central role for guidance in complex CBL and left main PCI, it is expected that angiography will continue to be the primary guidance modality for CBL PCI, principally due to educational and economic barriers. Mindful of the restricted access/adoption of intracoronary imaging for CBL PCI, the EBC board decided to review and describe a series of tips and tricks which can help to optimise angiography-guided PCI for CBLs. The identified key points for achieving an optimal angiography-guided PCI include a thorough analysis of pre-PCI images (computed tomography angiography, multiple angiographic views, quantitative coronary angiography vessel estimation), a systematic application of the technical steps suggested for a given selected technique, an intraprocedural or post-PCI use of stent enhancement and a low threshold for bailout use of intravascular imaging.

Maximizing tree carbon in croplands and grazing lands while sustaining yields

BackgroundIntegrating trees into agricultural landscapes can provide climate mitigation and improves soil fertility, biodiversity habitat, water quality, water flow, and human health, but these benefits must be achieved without reducing agriculture yields. Prior estimates of carbon dioxide (CO2) removal potential from increasing tree cover in agriculture assumed a moderate level of woody biomass can be integrated without reducing agricultural production. Instead, we used a Delphi expert elicitation to estimate maximum tree covers for 53 regional cropping and grazing system categories while safeguarding agricultural yields. Comparing these values to baselines and applying spatially explicit tree carbon accumulation rates, we develop global maps of the additional CO2 removal potential of Tree Cover in Agriculture. We present here the first global spatially explicit datasets calibrated to regional grazing and croplands, estimating opportunities to increase tree cover without reducing yields, therefore avoiding a major cost barrier to restoration: the opportunity cost of CO2 removal at the expense of agriculture yields.ResultsThe global estimated maximum technical CO2 removal potential is split between croplands (1.86 PgCO2 yr− 1) and grazing lands (1.45 PgCO2 yr− 1), with large variances. Tropical/subtropical biomes account for 54% of cropland (2.82 MgCO2 ha− 1 yr− 1, SD = 0.45) and 73% of grazing land potential (1.54 MgCO2 ha− 1 yr− 1, SD = 0.47). Potentials seem to be driven by two characteristics: the opportunity for increase in tree cover and bioclimatic factors affecting CO2 removal rates.ConclusionsWe find that increasing tree cover in 2.6 billion hectares of agricultural landscapes may remove up to 3.3 billion tons of CO2 per year – more than the global annual emissions from cars. These Natural Climate Solutions could achieve the Bonn Challenge and add 793 million trees to agricultural landscapes. This is significant for global climate mitigation efforts because it represents a large, relatively inexpensive, additional CO2 removal opportunity that works within agricultural landscapes and has low economic and social barriers to rapid global scaling. There is an urgent need for policy and incentive systems to encourage the adoption of these practices.

Innovaciones en Agricultura Sostenible: Un Estudio Exploratorio de las Nuevas Tendencias

The article “Innovations in Sustainable Agriculture: An Exploratory Study of Emerging Trends” addresses the impact of advanced technologies and agroecological practices on agricultural sustainability. The objective is to analyze emerging trends in sustainable agriculture and the factors influencing their adoption. The methodology is based on a comprehensive literature review, examining recent studies on precision agriculture, regenerative agriculture and the use of artificial intelligence and robotics. The results show that, although technologies such as drones and AI have transformed the sector, adoption faces economic barriers, such as high costs and lack of access to financing and training. The discussion highlights the need for inclusive public policies and greater investment in research to overcome these barriers and promote the adoption of sustainable technologies. It is concluded that collaboration between governments, the private sector and academic institutions is essential to accelerate the transition to a more equitable and resilient agriculture.

PFAS distribution in cascade derived foam at wastewater treatment plants: The role of non-linear drainage, collapse induced enrichment, and implications for removal

Per- and polyfluorinated alkyl substances (PFAS) enrichment in foam was investigated for the first time at a wastewater treatment plant cascade. A novel sampling device was utilized to allow spatial and temporal heterogeneity in PFAS concentrations and liquid content to be characterized. Concentrations of 8 PFAS compounds were normalized to liquid content and fit to a power law model revealing strong correlation (R2 = 0.91) between drainage induced enrichment and PFAS molar volume. Short chain PFAS such as perfluorobutanoate (PFBA) exhibited minor to no enrichment factors in foam (0.24–5.9) compared to effluent concentrations across the range of foam liquid contents (0.28–6.24 %), while long chain compounds such as perfluorooctane sulfonate (PFOS) became highly enriched with factors of 295–143,000. A conceptual model is proposed to explain higher than expected enrichment of more surface-active PFAS relative to liquid content, which combines continuous partitioning of PFAS to air bubbles during foam formation with additional partitioning during non-linear drainage and foam collapse, both controlled by their affinity for the air-water interface. Scoping calculations suggest the majority of PFOS and other long chain PFAS may be removed if foam is continuously collected with potential to reduce waste volume under economic barriers for current destructive technologies.

Fundamental Barriers to Green Energy Production in Selected EU Countries

Most EU countries are trying to develop new sources of energy to meet local power requirements due to energy shortages. The most popular renewable energy developments include biogas stations, wind turbines, water turbines, and solar systems. This article focuses on reviewing studies concerning the utilization of solar energy systems, especially photovoltaic (PV) ones, in European countries such as Germany, Italy, Spain, and Poland, which are leaders in PV installations. The review identifies factors influencing the development of PV investments and the energy situation in these countries. Economic, market, environmental, and infrastructural barriers, as well as driving factors, are presented. In all countries, the majority of installations were in the prosumer sector, with only a very small percentage in the state-owned sector. The methodology of the study covered the mentioned barriers, which were identified using scientific databases such as Scopus, Web of Science, and branch organizations websites like the International Renewable Energy Agency (IRENA). The novelty of the article lies in its examination of special barriers concerning green energy production in chosen EU countries. Normally, when reading articles on PV installations, as presented in the References section, one primarily observes a description of the construction process without deep involvement in the presented ideas.

Drone Technology for Crop Disease Resistance: Innovations and Challenges

Drones have been used for diverse application purposes in precision agriculture and new ways of using them are being explored. Many drone applications have been developed for different purposes such as pest detection, crop yield prediction, crop spraying, yield estimation, water stress detection, land mapping, identifying nutrient deficiency in plants, weed detection, livestock control, protection of agricultural products and soil analysis. Drones can create georeferenced maps that pinpoint the exact location of disease outbreaks within a field. These maps help farmers and agronomists monitor disease progression and plan targeted interventions. Drone operations are highly dependent on weather conditions. High winds, rain, and fog can hinder drone flights and affect the quality of images captured. Addressing technical limitations, regulatory and safety concerns, economic barriers, and data management issues will be crucial for the widespread adoption of drones in agriculture. By overcoming these challenges, drone technology can become a vital tool in sustainable and effective crop disease management.

Understanding invisible pain in the older adult: a content analysis of social media's representation of herpes zoster vaccine.

Herpes zoster (HZ), a common disease in older adults, affects their quality of life. Therefore, this study aimed to examine the blog posts of HZ-related information on social media platforms to analyze the attitudes and behaviors of residents toward the dissemination of health information. This research used content analysis to focus on Weibo, a representative social media in China, to analyze the content of 1866 blog posts related to herpes zoster (HZ) and herpes zoster vaccine (HZV). According to the consistency test by Cohen's Kappa, four themes were identified: (a) sources, (b) tones, (c) epidemiological information, and (d) extended parallel process model elements. The findings showed that most information on Weibo came from non-professionals, with a neutral tone, and showed the invisible pain of HZ and the effectiveness of HZV through the two largest aspects of prevention and aged protection in epidemiological information. However, current blog posts treat the older adult as invisible individuals, failing to acknowledge them as recipients of the information. Additionally, the cost of the vaccine acts as an invisible economic barrier, contributing to the dissemination of incorrect information about folk remedies. This impacts the older adult's acceptance of health information related to HZV. Thus, the way to share health information with the older adult needs to be improved in the future, and attention should be paid to the transmission of incorrect information to improve their vaccination rates and awareness of health management.

Extended Reality-Based Head-Mounted Displays for Surgical Education: A Ten-Year Systematic Review.

Surgical education demands extensive knowledge and skill acquisition within limited time frames, often limited by reduced training opportunities and high-pressure environments. This review evaluates the effectiveness of extended reality-based head-mounted display (ExR-HMD) technology in surgical education, examining its impact on educational outcomes and exploring its strengths and limitations. Data from PubMed, Cochrane Library, Web of Science, ScienceDirect, Scopus, ACM Digital Library, IEEE Xplore, WorldCat, and Google Scholar (Year: 2014-2024) were synthesized. After screening, 32 studies comparing ExR-HMD and traditional surgical training methods for medical students or residents were identified. Quality and bias were assessed using the Medical Education Research Study Quality Instrument, Newcastle-Ottawa Scale-Education, and Cochrane Risk of Bias Tools. Results indicate that ExR-HMD offers benefits such as increased immersion, spatial awareness, and interaction and supports motor skill acquisition theory and constructivist educational theories. However, challenges such as system fidelity, operational inconvenience, and physical discomfort were noted. Nearly half the studies reported outcomes comparable or superior to traditional methods, emphasizing the importance of social interaction. Limitations include study heterogeneity and English-only publications. ExR-HMD shows promise but needs educational theory integration and social interaction. Future research should address technical and economic barriers to global accessibility.

Assessing the Validity of the Centers for Medicare & Medicaid Services Measure in Identifying Potentially Preventable Emergency Department Visits by Patients With Cancer.

The Centers for Medicare & Medicaid Services (CMS) implemented chemotherapy measures (OP-35) to reduce potentially preventable emergency department visits (PPEDVs) and hospitalizations. This study evaluated the validity of the OP-35 measure in identifying PPEDVs among patients with cancer. This is a cross-sectional study, which used data from the 2012-2022 National Hospital Ambulatory Medical Care Survey. ED visits are assessed and compared on the basis of three measures: immediacy using Emergency Severity Index (ESI), disposition (discharge v hospitalization), and OP-35 criteria. Between 2012 and 2022, a weighted sample of 46,723,524 ED visits were made by patients with cancer. Among reported ESI cases, 25.2% (8,346,443) was high urgency. In addition, 30.3% (14,135,496) of ED visits among patients with cancer led to hospitalizations. Using the OP-35 measure, it was found that 20.85% (9,743,977) was PPEDVs. A 21.9% (10,232,102) discrepancy between discharge diagnosis (CMS billing codes) and chief complaints was identified. Further analysis showed that 19.2% (1,872,556) of potentially preventable ED visits (CMS OP-35) were high urgency and 32.6% (3,181,280) resulted in hospitalization. The CMS approach to identifying PPEDVs has limitations. First, it may overcount preventable visits by including high-urgency or hospitalization-requiring cases. Second, relying on final diagnoses for retrospective preventability judgment can be misleading as they may not reflect the initial reason for the visit. In addition, differentiating causes for ED visits in patients with cancer undergoing various treatments is challenging as the approach does not distinguish between chemotherapy-related complications and others. Identification inconsistencies arise because of varying coding practices and chosen preventable conditions, lacking consensus and alignment with specific hospital or patient needs. Finally, the model fails to consider crucial nonclinical factors like social support, economic barriers, and alternative care access, potentially unfairly penalizing hospitals serving underserved populations.

Cultivating purpose and internalized motivation through workplace learning

Building on prior research documenting associations between youth purpose and academic, psychological and physical well-being, this study examined the contributions of workplace learning (WPL) to youth purpose and internal motivation among 281 youth of diverse racial and ethnic identities and economic status enrolled in two high school networks offering innovatively designed WPL. Sequential regression analyses revealed that the quality of WPL, defined by mentor support for training, learning opportunities, and youth autonomy, contributed positively to youth purpose and internal motivation, beyond the negative effects of perceived social and economic barriers. Findings are discussed through the perspectives of psychology of working, decent education, self-determination theory and career construction and suggest that WPL is a promising intervention for overcoming inequities in fostering youth talent and purpose, including personal goals, meaning and intentions for social contribution.

Barriers to initial COVID-19 booster among U.S. adults who completed a primary vaccine series in the CHASING COVID cohort, September 2021 - October 2022.

It is crucial to understand factors associated with COVID-19 booster uptake in the U.S. given the updated COVID-19 vaccine recommendations. Using data from a national prospective cohort (N=4,616) between September 2021-October 2022, we examined socioeconomic, demographic, and behavioral factors of initial booster uptake among participants fully-vaccinated with the primary COVID-19 vaccines series. Cox proportional hazards models were used to estimate the associations of each factor with time to initial booster uptake. Most participants (86.5%) reported receiving their initial booster. After adjusting for age, race/ethnicity, education, region, and employment, participants with greater risk for severe COVID-19 had similar booster uptake compared with those with lower risk (aHR: 1.04; 95% CI: 0.95, 1.14). Participants with greater barriers to healthcare (aHR: 0.89; 95% CI: 0.84, 0.96), food insecurity (aHR: 0.82; 95% CI: 0.75, 0.89), and housing instability (aHR: 0.81; 95% CI: 0.73, 0.90) were less likely to report receiving initial booster compared with those without those barriers. Factors motivating the decision to vaccinate changed from safety-related concerns for the primary series to perceived need for the booster. It is key to address economic and health access barriers to achieve equitable COVID-19 vaccine uptake and continued protection against COVID-19.

Unpacking stakeholder perceptions on challenges for increasing adoption of solar-powered irrigation systems in India: A Q methodology study

Abstract Solar-powered irrigation systems (SPISs) are instruments for sustainable energy transition in agriculture. Despite the government of India's efforts, the adoption of SPIS has remained low. This paper uses the Q method to examine shared stakeholder views on the challenges of increasing SPIS adoption. The aim is to understand barriers to and drivers for SPIS adoption, and the necessary institutional setting to scale up adoption. To capture the discourse on challenges to SPIS adoption, a Q sample of 20 statements was extracted after stakeholder interviews and expert ratings. The statements were Q sorted by 22 respondents across SPIS stakeholder groups. Factor analysis identifies two distinct perspectives on constraints to expanding SPIS: (1) economic and financial barriers; and (2) institutional and governance challenges. This calls for re-framing SPIS from the incentive side of things and convergence across concerned implementing agencies.

Universal mental health curricula in public schools: Integrating mental health into physical education

AbstractMental health problems are ubiquitous, yet public schooling lacks comprehensive mental health curricula. The purpose of public education, in part, is to prepare people to face life and contribute to society. In the same vein as physical education (PE), we argue that a universal mental health curriculum could benefit the entire population. Schools across the globe, including in the United States, are beginning to explore universal mental health curricula, which could yield benefits that reach beyond mental health and wellness, to improve physical health, reduce behavioral problems, and increase academic performance. But the road ahead is marked with considerable economic and political barriers. We argue for incorporating mental health into the PE curriculum to gain traction toward a more comprehensive mental health curriculum.

Next-generation bioinformatics: An ultrafast and user-friendly tool for phylogenomic data exploration.

With increasingly large genomic datasets, even routine bioinformatic tasks can be arduous, computationally demanding, and time-consuming. Additionally, most bioinformatic programs do not have a graphical user interface (GUI) and thus, require users to be minimally competent in command-line. These impediments present significant economic and technological barriers for practitioners who do not have access to advanced computational resources and support. In this issue of Molecular Ecology Resources, Handika and Esselstyn (2024) developed an ultrafast and memory-efficient bioinformatic tool, SEGUL, that performs common manipulations and calculations of summary statistics on phylogenomic datasets. SEGUL has two main features that distinguish it from other bioinformatic programs: (1) it is based on the recently emergent, high-performance programming language Rust, and (2) it has a GUI written using Flutter, a cross-platform programming framework that also supports mobile operating systems (mobile iOS, iPadOS and Android). By leveraging and combining the power of Rust and Flutter, SEGUL achieves significantly faster computation times and lower memory usage across different platforms and CPU architectures compared to similar programs. The unique and innovative features of SEGUL pave the way for a new era of bioinformatics that can be more energy-efficient, inclusive, and available to a broader swathe of users.

Open Innovation as Fuel for the Circular Economy: an Analysis of the Italian Context

In recent years the circular economy (CE) has gained considerable interest in the academic debate as a tool for achieving sustainable development. The implementation of the circular economy model requires innovation to overcome technological, economic, environmental, social, and regulatory barriers. However, companies do not always have the means to innovate due to lack of information, limited technical skills and financial constraints; as a result, innovation remains a fragmented phenomenon. Open Innovation (OI) is a tool identified in the literature as useful for overcoming this problem and thus for the development of the CE, as it accelerates the exchange of knowledge and the realisation of the necessary innovations. Despite this, the relationship between CE and OI, and particularly the influence of OI on CE, has been little investigated. In line with this, the paper aims to explore this relationship by analysing the process through which OI supports the development of the CE, focusing on the knowledge exchange aimed at circular innovation, and categorising the actors contributing to this process and their roles. The study adopts a qualitative approach and uses methods of descriptive analysis and case studies. The sample consists of 240 Italian circular organisations that support circularity in different ways. The results made it possible to classify the main actors involved and their contributions to the CE through OI practices, revealing unseen circular activities that support classical circular activities (slowing, closing, and narrowing of material and energy circuits) and are identified in services, technology or research. As a theoretical contribution, the research provides a framework describing the actions and relationships among the actors involved in the CE initiatives, with a focus on the Living Lab practices.

Women's representation in higher leadership positions in Ethiopia in the last three decades since 1991.

Gender equality in decision-making positions is crucial to achieving the goals of good governance, peace, democracy, and inclusive/sustainable development. The major aim of this research article is to investigate the representation trend of women in higher decision-making positions over the last thirty years, since 1991. The federal three organs of government (law formulating, law enforcing, and law interpreting bodies) were the focus of this research. This research is a mixed type of research that inculcates both qualitative and quantitative data types. Secondary data sources from relevant government institutions were mostly used. The data was analyzed through content analysis of documents and presented via descriptive data presenting techniques. The research findings reveal that although women's representation in positions of decision-making has advanced considerably in recent years, the empirical data throughout the previous thirty years demonstrated the underrepresentation of women in higher leadership positions within the Ethiopian federal government. Furthermore, Women never held certain higher-level government leadership positions, such as the Prime Minister position, which seems to be forbidden for women. Women made up 23%, 19%, 19%, and 24% of the House of Peoples Representatives (HPR), the House of Federation (HoF), ministerial posts, and judicial bodies, respectively over the last three decades. Women are visibly underrepresented in the executive positions as compared to others. Thus, substantial policy and practical initiatives are needed to remove institutional, social, and economic barriers to boost women's advanced visibility in senior leadership roles.

Elephant Grass (Pennisetum purpureum): A Bioenergy Resource Overview

Elephant grass (EG), or Pennisetum purpureum, is gaining attention as a robust renewable biomass source for energy production amidst growing global energy demands and the push for alternatives to fossil fuels. This review paper explores the status of EG as a sustainable bioenergy resource, integrating various studies to present a comprehensive analysis of its potential in renewable energy markets. Methods employed include assessing the efficiency and yield of biomass conversion methods such as pretreatment for bioethanol production, biomethane yields, direct combustion, and pyrolysis. The analysis also encompasses a technoeconomic evaluation of the economic viability and scalability of using EG for energy production, along with an examination of its environmental impacts, focusing on its water and carbon footprint. Results demonstrate that EG has considerable potential for sustainable energy practices due to its high biomass production and ecological benefits such as carbon sequestration. Despite challenges in cost competitiveness with traditional energy sources, specific applications like small-scale combined heat and power (CHP) systems and charcoal production show economic promise. Conclusively, EG presents a viable option for biomass energy, potentially playing a pivotal role in the biomass sector as the energy landscape shifts towards more sustainable solutions; although, technological and economic barriers need further addressing.
