RESUMO

Unemployment and inequality are growing concerns that disproportionately affect people with disabilities. We compared unemployment rates and barriers to labor market participation for persons with spinal cord injury (SCI) as an exemplary case of disability with different socioeconomic positions and from a cross-national perspective across 20 countries worldwide. We showed that persons with SCI have much higher unemployment rates than the general population. While this situation is many times worse for those in low-income groups, persons with SCI in high-income groups are often in a position comparable to the general population. The main barriers to entering the labor market are health status, the impossibility of finding suitable jobs, and the lack of information about employment opportunities. This is the first study that quantifies the extent of inequality in the labor market for persons with SCI. Across the 20 countries analyzed, facing disability has a much higher impact on those in low-income groups. This reality is explained by the fact that people in lower-income groups face many more barriers to entering the labor market than those in higher-income groups.

RESUMO

OBJECTIVE: To assess change in attitudes toward women who have experienced trauma and to describe interns' reflections regarding the provision of universal trauma precautions and the training sessions. METHODS: Dietetic interns participated in 3 2-hour trauma-informed care (TIC) training sessions. A multiple-methods design was used, incorporating a presurvey and postsurvey to assess change in attitudes and thematic analysis to assess self-reflections. RESULTS: The attitudes of the interns improved across all statements. Two components measuring attitudes about sympathetic feelings toward mothers with underlying trauma and substance use disorder during pregnancy and retaining custody of their children reached statistical significance (P < 0.05). Four themes were identified in the self-reflections: TIC training was informative, valuable, and warranted, and interns felt comfortable discussing TIC. CONCLUSIONS AND IMPLICATIONS: Students positively assessed the TIC training and changed their attitudes. Trauma-informed care can be effectively incorporated within dietetics education to support students in developing therapeutic relationships in their future nutrition care standards.

RESUMO

Vaccinia virus is a poxvirus that has been successfully leveraged to develop vaccines for smallpox, which is caused by the closely related Variola virus. Smallpox has been declared as 'eradicated' by the WHO in 1980; however, it still poses a potential bioterrorism threat. More recently, the spreading of monkeypox (MPox) in non-endemic countries has further highlighted the importance of continuing the exploration for druggable targets for poxvirus infections. The vaccinia H1 (VH1) phosphatase is the first reported dual specificity phosphatase (DUSP) able to hydrolyze both phosphotyrosine and phosphoserine/phosphotheonine residues. VH1 is a 20 kDa protein that forms a stable dimer and can dephosphorylate both viral and cellular substrates to regulate the viral replication cycle and host immune response. VH1 dimers adopt a domain swap mechanism with the first 20 amino acids of each monomer involved in dense electrostatic interaction and salt bridge formations while hydrophobic interactions between the N-terminal and C-terminal helices further stabilize the dimer. VH1 appears to be an ideal candidate for discovery of novel anti-poxvirus agents because it is highly conserved within the poxviridae family and is a virulence factor, yet it displays significant divergence in sequence and dimerization mechanism from its human closest ortholog vaccinia H1-related (VHR) phosphatase, encoded by the DUSP3 gene. As the dimeric quaternary structure of VH1 is essential for its phosphatase activity, strategies leading to disruption of the dimer structure might aid in VH1 inhibitor development.

RESUMO

Food insecurity is prevalent, affecting 1·2 billion people globally in 2021. However, the effects of food insecurity are unequally distributed across populations and climate-related shocks threaten to exacerbate food insecurity and associated health consequences. The mechanisms underlying this exacerbation at the household level are largely unknown. We aimed to synthesise the available evidence on the mechanisms connecting extreme climate events to household-level food insecurity and highlight the research gaps that must be addressed to inform better food security and health policy. For this systematic review, a comprehensive literature search was done by a medical librarian in February, 2021 for articles about food security and climate-related shocks. Relevant publications were identified by searching the following databases with a combination of standardised index terms and keywords: MEDLINE, Embase, CINAHL, GreenFILE, Environment Complete, Web of Science Core Collection, and Global Health. Searches were limited to human studies published in English. Included studies measured food security outcomes using indicators developed by the UN Food and Agricultural Organization (ie, consumption patterns, livelihood change, malnutrition, and mortality) and explained the mechanism behind the household-level or population-level food insecurity. Purely theoretical, modelling, and review studies were excluded. Quality assessment was conducted using the appropriate Joanna Briggs Institute Critical Appraisal Tool. Data were analysed using thematic analysis of the categories of mechanism (interpreted using internationally accepted frameworks), risk and resilience factors, and author policy recommendations. We found a paucity of data with only 18 studies meeting criteria for inclusion out of 337 studies identified for full-text review. All the studies that were included in our analysis showed worse food security outcomes after climate-related shocks. Food availability was the most common mechanism cited (17 studies), although most studies addressed at least one additional mechanism (15 studies). Studies were of mixed methodologies with nuanced discussions of risk and resilience factors, and of policy recommendations. This systematic review shows that there is an incomplete assessment of food security at the household and community level after climate-related shocks in the literature and finds that food availability is the primary mechanism studied. The low number of studies on this topic limits subgroup analysis and generalisability; however, the good quality of the studies allows for important policy recommendations around improving resilience to climate shocks and suggestions for future research including the need for a more granular understanding of mechanisms and feasible adaptation solutions.

RESUMO

INTRODUCTION: The therapeutic approach to the most common respiratory diseases, asthma and chronic obstructive pulmonary disease (COPD), involves the use of inhalation devices. Its use is essential, but incorrect use is frequent, and learning and reviewing the technique is necessary for the adequate management of these diseases. OBJECTIVE: This study aims to increase the knowledge of health professionals from pharmacies in the municipality of Matosinhos, Portugal, about the correct inhalation technique. METHODS: The project developed from May 2022 to June 2023 was based on a training session for pharmacy professionals that took place after professionals completed a questionnaire and after evaluating each participant's inhalation technique by the authors using a checklist. Both were reapplied three months after the first evaluation. RESULTS: Fifteen pharmacies in Matosinhos, Portugal, were invited, of which eight agreed to participate, with a total of 16 health professionals (30.8% of professionals in these pharmacies). We found that professionals questioned and taught users more times about the inhalation technique and that a greater number of professionals considered they knew how to correctly perform the inhalation technique in the second assessment. It was also possible to verify statistically significant differences (p<0.001) between the mean of correct steps in the inhalation technique between the first and second assessments. There was also an improvement in the qualitative analysis of errors in the inhalation technique. In the first assessment, the inhalation devices with the lowest percentage of correct steps were Forspiro® and Respimat®. In the second evaluation, the Diskus® and Ellipta® devices obtained 100% correct steps, with the K-haler® being the device with the lowest percentage. CONCLUSIONS: This study confirms the effectiveness of continuous training for health professionals and the importance of multidisciplinary cooperation in teaching inhalation techniques. Other studies are needed to complement these results, particularly with representative samples of the general population, or assessing the impact of this intervention in patients with respiratory diseases.

RESUMO

Water pollution poses a global threat to ecosystems and human health and is driven by the presence of various contaminants in wastewater, including nano- and microplastics. Despite the magnitude of this problem, the majority of global wastewater is released untreated into water bodies. To combat this issue, a multi-strategy approach is needed. This study explores a circular economy-based solution for treating emerging pollutants, particularly wastewater from ophthalmic spectacle lens production. Our approach integrates solid waste materials into polymeric and cement matrices while also utilising wastewater for microalgae cultivation. This innovative strategy focuses on biomass generation and economic valorisation. By adopting a circular economy model, we aim to transform environmental pollutants from wastewater into valuable organic products. A key component of our approach is the utilisation of microalgae, specifically Nannochloropsis sp., known for its high lipid content and resilience. This microalgae species serves as a promising biobased feedstock, supporting the production of innovative biobased products, such as biopolymers, for ophthalmic lens manufacturing. Our interdisciplinary approach combines microalgae technology, analytical chemistry, cement production, and polymer processing to develop a sustainable circular economy model that not only addresses environmental concerns, but also offers economic benefits. This study underscores the potential of harnessing high-value products from waste streams and underscores the importance of circular economy principles in tackling pollution and resource challenges.

RESUMO

This study examined dietetics students' perceptions of coronavirus disease-2019 (COVID-19) pandemic impacts on academics and mental and physical health. Data were collected via a cross-sectional online survey in February to March 2021 from undergraduate dietetics students across the United States. Among the 526 students who participated, during the fall 2020 semester, 87% experienced increased stress, 64% reported mental health concerns, and 32% reported disordered eating. Sixty-two percent agreed their program met educational needs; however, 62% also agreed COVID-19 negatively impacted the quality of education and 49% agreed to learning less than normal. Pandemic impacts are critical to consider as students enter dietetic internships and start careers.

RESUMO

Because the world's population is increasing, science-based policies are needed to promote sustainable global development. It is important to maintain and restore the environment and help human society overcome the risks from industrialization and unsustainable exponential growth. In recent years, many studies have highlighted that macroalgae represent a key marine resource for ecological and sustainable living, thus helping to address today's global problems, such as water pollution, ocean acidification, and global warming. Macroalgae show the potential to provide innovative, ecofriendly, and nutritious food sources and natural compounds for various industries, such as biomedical, food, agricultural, and pharmaceutical industries. This review discusses how macroalgae can help us today and how they can promote a more sustainable way of life in the future. It also discusses the potential danger for ecosystems and the global population if these organisms are not part of the solution but part of the problem.

RESUMO

BACKGROUND: The novel coronavirus disease 2019 (COVID-19) pandemic disrupted food systems and economies across the United States. Public health measures, including stay-at-home orders, led to employment disruptions and food system shocks that increased barriers to food access. OBJECTIVES: We aimed to examine food insecurity and food access challenges in New Mexico (NM) during the COVID-19 pandemic. METHODS: A cross-sectional study using a validated survey was conducted in NM in May and June 2020. Adults 18 y and older were recruited through convenience sampling via email, websites, and targeted social media ads from major universities, nongovernmental organizations, state agencies, and media outlets. Survey questions assessed food insecurity and food-related challenges and worry. Bivariate and multivariate logistic regression examined relations between food insecurity and demographic characteristics. z Tests were used to compare the proportions of individuals who responded affirmatively to food challenge and worry questions between food-secure and food-insecure respondents. RESULTS: A total of 1487 residents participated in the study. Thirty percent of respondents reported experiencing food insecurity and 16% experienced very low food security since the pandemic started. Food insecurity was associated with each of 7 characteristics examined in bivariate logistic regression analyses. Multivariate logistic regression results showed that Hispanic (adjusted OR: 1.70; 95% CI: 1.18, 2.44) and female (adjusted OR: 1.78; 95% CI: 1.09, 2.90) respondents were more likely to experience food insecurity than non-Hispanic white and male respondents. Larger household sizes were associated with higher odds of food insecurity except for those in the lowest and highest income categories. z Tests showed that a higher proportion of food-insecure respondents experienced food-related challenges and worry than food-secure respondents. CONCLUSIONS: Disparities in food insecurity persisted during the COVID-19 pandemic and food-insecure individuals were more likely to report experiencing food-related challenges and worry. Researchers and policy makers in NM may consider continuing efforts to mitigate food access issues as the pandemic continues.

RESUMO

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic profoundly affected food systems including food security. Understanding how the COVID-19 pandemic impacted food security is important to provide support and identify long-term impacts and needs. OBJECTIVE: The National Food Access and COVID research Team (NFACT) was formed to assess food security over different US study sites throughout the pandemic, using common instruments and measurements. This study presents results from 18 study sites across 15 states and nationally over the first year of the COVID-19 pandemic. METHODS: A validated survey instrument was developed and implemented in whole or part through an online survey of adults across the sites throughout the first year of the pandemic, representing 22 separate surveys. Sampling methods for each study site were convenience, representative, or high-risk targeted. Food security was measured using the USDA 6-item module. Food security prevalence was analyzed using ANOVA by sampling method to assess statistically significant differences. RESULTS: Respondents (n = 27,168) indicate higher prevalence of food insecurity (low or very low food security) since the COVID-19 pandemic, compared with before the pandemic. In nearly all study sites, there is a higher prevalence of food insecurity among Black, Indigenous, and People of Color (BIPOC), households with children, and those with job disruptions. The findings demonstrate lingering food insecurity, with high prevalence over time in sites with repeat cross-sectional surveys. There are no statistically significant differences between convenience and representative surveys, but a statistically higher prevalence of food insecurity among high-risk compared with convenience surveys. CONCLUSIONS: This comprehensive study demonstrates a higher prevalence of food insecurity in the first year of the COVID-19 pandemic. These impacts were prevalent for certain demographic groups, and most pronounced for surveys targeting high-risk populations. Results especially document the continued high levels of food insecurity, as well as the variability in estimates due to the survey implementation method.

RESUMO

Presently, there is a high demand for nutritionally enhanced foods, so it is a current challenge to look at new raw food sources that can supplement beneficially the human diet. The nutritional profile and key secondary metabolites of red seaweeds (Rhodophyta) are gaining interest because of this challenge. In this context, the possible use of the red seaweed Chondracanthus teedei var. lusitanicus (Gigartinales) as a novel nutraceutical source was investigated. As a result, we highlight the high mineral content of this seaweed, representing 29.35 g 100 g-1 of its dry weight (DW). Despite the low levels of calcium and phosphorus (0.26 and 0.20 g 100 g-1 DW, respectively), this seaweed is an interesting source of nitrogen and potassium (2.13 and 2.29 g-1 DW, accordingly). Furthermore, the high content of carbohydrates (56.03 g 100 g-1 DW), which acts as dietary fibers, confers a low caloric content of this raw food source. Thus, this study demonstrates that C. teedei var. lusitanicus is in fact an unexploited potential resource with the capability to provide key minerals to the human diet with promising nutraceutical properties.

RESUMO

The overexploitation of terrestrial habitats, combined with the ever-growing demand for food, has led to the search for alternative food sources. The importance of seaweeds as food sources has been growing, and their potential as sources of fatty acids (FA) make seaweeds an interesting feedstock for the food and nutraceutical industries. The aim of this study is to assess the potential of five red seaweeds (Asparagospis armata, Calliblepharis jubata, Chondracanthus teedei var. lusitanicus, Gracilaria gracilis, and Grateloupia turuturu) and three brown seaweeds (Colpomenia peregrina, Sargassum muticum and Undaria pinnatifida), harvested in central Portugal, as effective sources of essential FA for food or as dietary supplements. FA were extracted from the biomass, transmethylated to methyl esters, and analyzed through gas chromatography-mass spectrometry. G. gracilis presented the highest content of saturated fatty acids (SFA) (41.49 mg·g-1), whereas C. jubata exhibited the highest content of highly unsaturated fatty acids (HUFA) (28.56 mg·g-1); the three G. turuturu life cycle stages presented prominent SFA and HUFA contents. Omega-6/omega-3 ratios were assessed and, in combination with PUFA+HUFA/SFA ratios, it is suggested that C. jubata and U. pinnatifida may be the algae with highest nutraceutical potential, promoting health benefits and contributing to a balanced dietary intake of fatty acids.

RESUMO

To exploit the nutraceutical and biomedical potential of selected seaweed-derived polymers in an economically viable way, it is necessary to analyze and understand their quality and yield fluctuations throughout the seasons. In this study, the seasonal polysaccharide yield and respective quality were evaluated in three selected seaweeds, namely the agarophyte Gracilaria gracilis, the carrageenophyte Calliblepharis jubata (both red seaweeds) and the alginophyte Sargassum muticum (brown seaweed). It was found that the agar synthesis of G. gracilis did not significantly differ with the seasons (27.04% seaweed dry weight (DW)). In contrast, the carrageenan content in C. jubata varied seasonally, being synthesized in higher concentrations during the summer (18.73% DW). Meanwhile, the alginate synthesis of S. muticum exhibited a higher concentration (36.88% DW) during the winter. Therefore, there is a need to assess the threshold at which seaweed-derived polymers may have positive effects or negative impacts on human nutrition. Furthermore, this study highlights the three polymers, along with their known thresholds, at which they can have positive and/or negative health impacts. Such knowledge is key to recognizing the paradigm governing their successful deployment and related beneficial applications in humans.

RESUMO

Seaweeds are a potential source of bioactive compounds that are useful for biotechnological applications and can be employed in different industrial areas in order to replace synthetic compounds with components of natural origin. Diverse studies demonstrate that there is a solid ground for the exploitation of seaweed bioactive compounds in order to prevent illness and to ensure a better and healthier lifestyle. Among the bioactive algal molecules, phenolic compounds are produced as secondary metabolites with beneficial effects on plants, and also on human beings and animals, due to their inherent bioactive properties, which exert antioxidant, antiviral, and antimicrobial activities. The use of phenolic compounds in pharmaceutical, nutraceutical, cosmetics, and food industries may provide outcomes that could enhance human health. Through the production of healthy foods and natural drugs, bioactive compounds from seaweeds can help with the treatment of human diseases. This review aims to highlight the importance of phenolic compounds from seaweeds, the scope of their production in nature and the impact that these compounds can have on human and animal health through nutraceutical and pharmaceutical products.

RESUMO

BACKGROUND: Feeding and eating disorders present with a variety of medical complications, some of which may be life-threatening. Emergency Medicine (EM) physicians may interact with patients with eating disorders, however, EM physicians' knowledge and perceptions of resources for treating patients with eating disorders have not been examined. The purpose of this study was to explore previous training/education, perceptions of available resources, and educational needs in treating eating disorders in practicing EM physicians. METHODS: An investigator-developed survey was used in this cross-sectional pilot study, distributed to EM Residency Program Coordinators in the United States to distribute to EM physicians and residents. The survey assessed EM physicians' previous training and education in treating and diagnosing eating disorders. The primary outcomes assessed were participants' previous training/education in eating disorders, knowledge of local resources for patients, and educational needs on a variety of topics related to adult and adolescent eating disorders. Data were described descriptively and SAS 9.4 was used to analyze data. RESULTS: Of the 162 participants, just 1.9% completed a rotation on eating disorders during residency. Ninety-three percent were unfamiliar with the American Psychiatric Association's Practice Guideline for the Treatment of Patients with Eating Disorders; 95% were unfamiliar with the publication, "Emergency Department management of patients with eating disorders" by Trent et al. The majority were not aware of resources for patients with eating disorders including community and online support groups, the National Eating Disorders Association, and local treatment programs. At least 50% agreed additional education on 15 of the 19 topics examined would be useful; 85% agreed to wanting education on the assessment of patients with eating disorders in the Emergency Department. CONCLUSIONS: Most EM physicians lack training in eating disorders and knowledge of resources available for patients post-Emergency Department discharge. EM physicians agree additional education on a number of topics would be beneficial, particularly assessment of eating disorders in the Emergency Department, medical complications of eating disorders, and hospital admission criteria for those with eating disorders.

RESUMO

Nutrition and dietetics practice should be based on the highest-quality and most recent available evidence. Unfortunately, translating research to day-to-day practice often involves long lag times. Implementation science is an emerging field that evaluates methods that promote uptake of research findings into daily practice. Numerous theories and frameworks have been developed to provide guidance for implementation research and operationalization of recommendations. This paper provides a broad overview of implementation science and highlights frameworks such as the Normalization Process Theory that can be used by registered dietitian nutritionist (RDNs) to encourage systematic uptake of evidence into practice.

RESUMO

The introduction of exotic organisms in marine ecosystems can lead to economic and ecological losses. Globally, seaweeds represent a significant part of these non-indigenous species (NIS), with 407 introduced algal species. Furthermore, the presence of NIS seaweeds has been reported as a major concern worldwide since the patterns of their potential invasion mechanisms and vectors are not yet fully understood. Currently, in the Iberian Peninsula, around 50 NIS seaweeds have been recorded. Some of these are also considered invasive due to their overgrowth characteristic and competition with other species. However, invasive seaweeds are suitable for industrial applications due to their high feedstock. Hence, seaweeds' historical use in daily food diet, allied to research findings, showed that macroalgae are a source of nutrients and bioactive compounds with nutraceutical properties. The main goal of this review is to evaluate the records of NIS seaweeds in the Iberian Peninsula and critically analyze the potential of invasive seaweeds application in the food industry.

RESUMO

The effects of the abiotic inducers ß-glucan, extracted from Shiitake (Lentinula edodes), BFIICaB® (Kappaphycus alvarezii) and BKPSGII® (K. alvarezii X Sargassum sp.) on tomato plants infected with Fusarium oxysporum f. sp. lycopersici (FOL) were evaluated through the activity of enzymes related to the induction of resistance at 5 and 10 days after inoculation (DAI). Tomato plants (21 days old, after germination) were inoculated with the pathogen conidia suspension and sprayed with 0.3% aqueous solutions of the inducers. The activities of the enzymes ß-1,3-glucanase, peroxidase and phenylalanine ammonia lyase (PAL) were evaluated in fresh tomato leaves collected at 5 and 10 DAI. In all treatments, peroxidase showed the highest enzymatic activity, followed by ß-1,3-glucanase and PAL. Between the seaweeds, the inducers extracted from the red alga Kappaphycus alvarezii (BFIICaB®) promoted the highest enzymatic activity. The exception was BKPSGII® (K. alvarezii X Sargassum sp.) where the influence of Sargassum sp. resulted in higher peroxidase activity (4.48 Δab600 mg P-1 min-1) in the leaves, 10 DAI. Both the red seaweed K. alvarezii and the brown alga Sargassum sp. promoted activities of ß-1,3-glucanase, peroxidase and PAL.
