RESUMO

Amidst the cost-of-living crisis the UK news has been increasingly reporting of individuals "choosing between heating and eating," suggesting overlapping food and fuel poverty (FFP). The media plays a powerful role in establishing narratives, shaping political debates, and even influencing what societies regard as an "issue" or a "public health issue." Relying on framing theory, this media analysis seeks to better understand how FFP have been constructed relationally in the UK news and how surrounding public health messaging has been employed. Using the NexisLexis database, we searched for UK news articles about intersecting FFP published between January 2010 and April 2022. After double screening, relevant data were extracted from 185 articles and data fragments were coded and analysed. FFP-focused news largely gained momentum in late 2021 into 2022. Two frame categories - descriptive and prescriptive - of FFP were identified. Descriptive frames explained the experience of FFP as a: trade-off between goods (71% of articles), mutual cutback of goods (28%), or just poverty (income/monetary poverty) (1%). Prescriptive frames assigned blame or responsibility to: government (59% of articles), food/fuel industry (13%), community or charity organisations (12%), or individuals (3%). Relatively few (29%) articles linked FFP with health consequences, and none framed it as a health issue. The prominence of the trade-off frame in the UK news suggests that FFP is a crucial topic for the UK public that requires joint attention. Despite the prominence of the government responsibility framing, the frame lacks accompanying prescriptions of consistent, specific, targeted solutions. A public health frame in the UK news may address this gap by outlining potential evidence-based solutions and increasing capacity by appointing responsible actors to help prevent and address this issue.

RESUMO

Pyridoxal-5'-phosphate (PLP) and derivatives of this cofactor enable a plethora of reactions in both enzyme-mediated and free-in-solution transformations. With few exceptions in each category, such chemistry has predominantly involved two-electron processes. This sometimes poses a significant challenge for using PLP to build tetrasubstituted carbon centers, especially when the reaction is reversible. The ability to access radical pathways is paramount to broadening the scope of reactions catalyzed by this coenzyme. In this study, we demonstrate the ability to access a radical PLP-based intermediate and engage this radical intermediate in a number of C-C bond-forming reactions. By selection of an appropriate oxidant, single-electron oxidation of the quinonoid intermediate can be achieved, which can subsequently be applied to C-C bond-forming reactions. Through this radical reaction pathway, we synthesized a series of α-tertiary amino acids and esters to investigate the substrate scope and identify nonproductive reaction pathways. Beyond the amino acid model system, we demonstrate that other classes of amine substrates can be applied in this reaction and that a range of small molecule reagents can serve as coupling partners to the semiquinone radical. We anticipate that this versatile semiquinone radical species will be central to the development of a range of novel reactions.

RESUMO

3-Hydroxyindolenines can be used to access several structural motifs that are featured in natural products and pharmaceutical compounds, yet the chemical synthesis of 3-hydroxyindolenines is complicated by overoxidation, rearrangements, and complex product mixtures. The selectivity possible in enzymatic reactions can overcome these challenges and deliver enantioenriched products. Herein, we present the development of an asymmetric biocatalytic oxidation of 2-arylindole substrates aided by a curated library of flavin-dependent monooxygenases (FDMOs) sampled from an ancestral sequence space, a sequence similarity network, and a deep-learning-based latent space model. From this library of FDMOs, a previously uncharacterized enzyme, Champase, from the Valley fever fungus, Coccidioides immitis strain RS, was found to stereoselectively catalyze the oxidation of a variety of substituted indole substrates. The promiscuity of this enzyme is showcased by the oxidation of a wide variety of substituted 2-arylindoles to afford the respective 3-hydroxyindolenine products in moderate to excellent yields and up to 95:5 er.

RESUMO

BACKGROUND: The burden of energy and fuel poverty (EFP) in Europe is increasing in the face of the cost-of-living crisis, the Russian invasion of Ukraine, the coronavirus disease 2019 (COVID-19) pandemic and the climate emergency. While the health impacts of EFP are often the driving reason for addressing it, EFP's association with health is poorly delineated. This review aims to scope the evidence of EFP's association with health in Europe. METHODS: A scoping review based on Arksey and O'Malley's framework was conducted using search terms relevant to EFP, health and Europe. Five databases were searched, in addition to hand searching. Review selection was performed by two independent reviewers, and articles were thematically analyzed. RESULTS: Thirty-five articles published between January 2000 and March 2022 were included. The literature varied in definitions and measurements of EFP and in the health indicators examined. The review revealed a negative association between EFP and health, specifically, general unspecified poor health (9 articles), excess winter mortality (3 articles), communicable diseases (3 articles), non-communicable diseases (11 articles), mental health (15 articles) and well-being (12 articles). While women were reported to be at a higher risk of EFP than men, children and older adults were identified as particularly vulnerable to EFP's adverse health repercussions. CONCLUSIONS: This scoping review illustrates a significant and complex association between EFP and various domains of health. Though heterogeneity across research makes it difficult to compare findings, our review supports the use of health as a justification to address EFP and urges public health to be more involved in EFP mitigation.

RESUMO

BACKGROUND: There is a large and growing unmet need for rehabilitation - a diverse category of services that aim to improve functioning across the life course - particularly in low- and middle-income countries. Yet despite urgent calls to increase political commitment, many low- and middle-income country governments have dedicated little attention to expanding rehabilitation services. Existing policy scholarship explains how and why health issues reach the policy agenda and offers applicable evidence to advance access to physical, medical, psychosocial, and other types of rehabilitation services. Drawing from this scholarship and empirical data on rehabilitation, this paper proposes a policy framework to understand national-level prioritization of rehabilitation in low- and middle-income countries. METHODS: We conducted key informant interviews with rehabilitation stakeholders in 47 countries, complemented by a purposeful review of peer-reviewed and gray literature to achieve thematic saturation. We analyzed the data abductively using a thematic synthesis methodology. Rehabilitation-specific findings were triangulated with policy theory and empirical case studies on the prioritization of other health issues to develop the framework. RESULTS: The novel policy framework includes three components which shape the prioritization of rehabilitation on low- and middle-income countries' national government's health agendas. First, rehabilitation lacks a consistent problem definition, undermining the development of consensus-driven solutions which could advance the issue on policy agendas. Second, governance arrangements are fragmented within and across government ministries, between the government and its citizens, and across national and transnational actors engaged in rehabilitation service provision. Third, national legacies - particularly from civil conflict - and weaknesses in the existing health system influences both rehabilitation needs and implementation feasibility. CONCLUSIONS: This framework can support stakeholders in identifying the key components impeding prioritization for rehabilitation across different national contexts. This is a crucial step for ultimately better advancing the issue on national policy agendas and improving equity in access to rehabilitation services.

RESUMO

BACKGROUND: Researchers have highlighted a large-scale global unmet need for rehabilitation. While sex and gender have been shown to interact with each other and with other social and structural factors to influence health and wellbeing, less is known about how sex and gender shape rehabilitation participation and outcomes within health systems. METHODS: Using an intersectional approach, we examine literature that explores the relationship between sex and/or gender and rehabilitation access, use, adherence, outcomes, and caregiving. Following a comprehensive search, 65 documents met the inclusion criteria for this scoping review of published literature. Articles were coded for rehabilitation-related themes and categorized by type of rehabilitation, setting, and age of participants, to explore how existing literature aligned with documented global rehabilitation needs. Responding to a common conflation of sex and gender in the existing literature and a frequent misrepresentation of sex and gender as binary, the researchers also developed a schema to determine whether existing literature accurately represented sex and gender. RESULTS: The literature generally described worse rehabilitation access, use, adherence, and outcomes and a higher caregiving burden for conditions with rehabilitation needs among women than men. It also highlighted the interacting effects of social and structural factors like socioeconomic status, racial or ethnic identity, lack of referral, and inadequate insurance on rehabilitation participation and outcomes. However, existing literature on gender and rehabilitation has focused disproportionately on a few types of rehabilitation among adults in high-income country contexts and does not correspond with global geographic or condition-based rehabilitation needs. Furthermore, no articles were determined to have provided an apt depiction of sex and gender. CONCLUSION: This review highlights a gap in global knowledge about the relationship between sex and/or gender and rehabilitation participation and outcomes within health systems. Future research should rely on social science and intersectional approaches to elucidate how gender and other social norms, roles, and structures influence a gender disparity in rehabilitation participation and outcomes. Health systems should prioritize person-centered, gender-responsive care, which involves delivering services that are responsive to the complex social norms, roles, and structures that intersect to shape gender inequitable rehabilitation participation and outcomes in diverse contexts.

RESUMO

Drink-driving is a major cause of global road traffic fatalities, yet few countries have laws that meet international best practices. One possible reason is the alcohol industry's opposition to meaningful policies that are perceived to directly threaten sales. Our primary objectives are to document alcohol industry involvement in global road safety policies and programmes and to critically evaluate the responses of public health and road safety communities to this involvement. Under the guidance of the Policy Dystopia Model, we used a mixed methods approach in which data were gathered from expert interviews and a mapping review of 11 databases, 5 watchdog websites and 7 alcohol industry-sponsored initiatives. Triangulation was used to identify points of convergence among data sources. A total of 20 expert interviews and 94 documents were analysed. Our study showed that the alcohol industry acknowledges that drink-driving is an issue but argues for solutions that would limit impact on sales, akin to the message 'drink-but do not drive'. Industry actors have been involved in road safety through: (1) coalition coupling and decoupling, (2) information production and management, (3) direct involvement in policymaking and (4) implementation of interventions. Our study also shed light on the lack of cohesion within and among the public health and road safety communities, particularly with regard to the topics of receiving funding from and partnering with the alcohol industry. These results were subsequently used to adapt the Policy Dystopia Model as a conceptual framework that illustrates the ways in which the alcohol industry has been involved in global road safety. Several implications can be drawn from this study, including the urgent need to increase awareness about the involvement of the alcohol industry in road safety and to build a cohesive transnational alcohol control advocacy alliance to curb injuries and deaths related to drink-driving.
