Is Buying Local Food a Sustainable Practice? A Scoping Review of Consumers’ Preference for Local Food

Access to healthy food and the introduction of sustainable nutrition practices are two important issues today. The COVID-19 pandemic has brought new challenges to food security but it has also provided opportunities for local food production. The discussion on local food has been gaining attention in recent years, but there is still a lack of clear understanding of the term ‘local food’ in the literature. The relationship between local food and sustainability issues is still unclear and has various connotations. This discordance leads to further discussions on whether buying local food should be considered a sustainable behavior and whether consumer preference for local food can be perceived as a sustainable practice. A scoping literature review was conducted in order to fill this gap and to shed light on the main tendencies of the scientific literature regarding this topic. The outcomes of the research revealed three dimensions of ‘local food’ definitions in the literature: geographical, geopolitical, and organic; while the problem of a unified local food definition remains open. The studied literature did not show any sound evidence for sustainability attributes in the definition of local food and consumer perception of local food.

Transmission of Onychomycosis and Dermatophytosis between Household Members: A Scoping Review

Onychomycosis is a common fungal infection of the nail, caused by dermatophytes, non-dermatophytes, and yeasts. Predisposing factors include older age, trauma, diabetes, immunosuppression, and previous history of nail psoriasis or tinea pedis. Though many biological risk factors have been well characterized, the role of the environment has been less clear. Studies have found evidence of transmission in 44% to 47% of households with at least one affected individual, but the underlying mechanisms and risk factors for transmission of onychomycosis between household members are incompletely understood. A scoping literature review was performed to characterize and summarize environmental risk factors involved in the transmission of onychomycosis within households. A total of 90 papers met the inclusion criteria, and extracted data was analyzed in an iterative manner. Shared household surfaces may harbor dermatophytes and provide sources for infection. Shared household equipment, including footwear, bedding, and nail tools, may transmit dermatophytes. The persistence of dermatophytes on household cleaning supplies, linen, and pets may serve as lasting sources of infection. Based on these findings, we provide recommendations that aim to interrupt household transmission of onychomycosis. Further investigation of the specific mechanisms behind household spread is needed to break the cycle of transmission, reducing the physical and social impacts of onychomycosis.

Pathophysiology of Circulating Biomarkers and Relationship With Vascular Aging: A Review of the Literature From VascAgeNet Group on Circulating Biomarkers, European Cooperation in Science and Technology Action 18216

Impairment of the arteries is a product of sustained exposure to various deleterious factors and progresses with time; a phenomenon inherent to vascular aging. Oxidative stress, inflammation, the accumulation of harmful agents in high cardiovascular risk conditions, changes to the extracellular matrix, and/or alterations of the epigenetic modification of molecules, are all vital pathophysiological processes proven to contribute to vascular aging, and also lead to changes in levels of associated circulating molecules. Many of these molecules are consequently recognized as markers of vascular impairment and accelerated vascular aging in clinical and research settings, however, for these molecules to be classified as biomarkers of vascular aging, further criteria must be met. In this paper, we conducted a scoping literature review identifying thirty of the most important, and eight less important, biomarkers of vascular aging. Herein, we overview a selection of the most important molecules connected with the above-mentioned pathological conditions and study their usefulness as circulating biomarkers of vascular aging.

Eras of Digital Entrepreneurship

While recent research continues to emphasize the importance of digital entrepreneurship, the historical terminology of this field is often overlooked. Digital entrepreneurship tends to be considered a new phenomenon despite emerging in the early 1990s. Building on a scoping literature review, this study analyzes 1354 publications that use nine different terms interchangeably to describe the phenomenon of digital entrepreneurship. Based on the number of publications per year, three eras in the historical development of digital entrepreneurship research are outlined. Digital technologies are identified as external enablers, and certain practical events are considered to be influencing factors. The results show that recent research has not adequately recognized the contributions of previous publications and that the understanding of digital entrepreneurship is quite similar with regard to the terms used and over time. This study shows how emerging digital technologies, such as artificial intelligence, blockchain technology, and big data analytics, might shape the future of digital entrepreneurship research. The study occupies the intersection between entrepreneurship and information systems literature and its main contribution is to provide new insights into the eras of digital entrepreneurship from the past to the present and into the future.

The Potential Contribution of Decentralized Anaerobic Digestion towards Urban Biowaste Recovery Systems: A Scoping Review

The potential contribution of decentralized approaches in implementing biowaste recovery systems has attracted interest in urban policy making and scientific research. Although the scientific literature on the topic is rapidly increasing, it is still limited and scattered. A comprehensive overview of current scientific knowledge is thus needed to support future research on decentralized options for biowaste recovery systems. Anaerobic digestion (AD) is a mature biowaste treatment technology that recovers energy and nutrients, and can close urban resource loops. Through a scoping literature review, this paper investigated decentralized AD and its potential contribution in implementing urban biowaste recovery systems. We identified opportunities and challenges for planning of decentralized AD, and concluded that these mainly concern: (a) digestate management; (b) the potential for local circularity with product valorization in outlets such as urban agriculture; and (c) the development and application of decision support tools. The findings highlighted the need to enhance scientific evidence on the impact of decentralized AD in different urban contexts. Results from published studies were highly context-specific, making it difficult to draw general conclusions. This study can support the transition to integrated planning of AD and wider urban biowaste recovery systems. Such planning must include a comprehensive analysis of configuration approaches.

Preventable? Long-Term Care Policy Successes and Failures During COVID-19 Pandemic: A Scoping Literature Review

The number of older adults who live in long-term care (LTC) is expected to increase worldwide. The COVID-19 pandemic has caused serious consequences in Canadian LTC homes, while homes in China and Japan reported minimal infection and death rates in residents. The differences in LTC policies may be one of the contributors. The purpose of this literature review was to identify elements of the LTC policies that might have impacted COVID-19 outcomes in LTC homes in Canada, China, and Japan. A scoping review was conducted following the framework proposed by Arksey and O’Malley. Scholarly articles and grey literature published between January 2015 and June 2020 were identified in six databases, four in English (CINAHL, Scopus, ProQuest, and PubMed), one in Chinese (CNKI), and one in Japanese (CiNii), using MeSH terms for LTC and health policy. Grey literature was identified using Google. Data were extracted, summarized and common themes identified through content analysis. A total of 52 articles and 26 grey sources were included in the review based on determined inclusion criteria. They were research articles, reviews, government or association reports, policy briefs, policy documents, and guides. Four common themes of challenges emerged: caregiver workforce, service provision, funding, and physical environments. Three sub-themes were identified for caregiver workforce and service provision. Differences in COVID-19 consequences in LTC homes in the three countries seem to be related mainly to the challenges with the caregiver workforce and the lack of funding. The result suggests Improvements of LTC policies are required, especially in Canada.
