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

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

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

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

Seaweeds have attracted high interest in recent years due to their chemical and bioactive properties to find new molecules with valuable applications for humankind. Phenolic compounds are the group of metabolites with the most structural variation and the highest content in seaweeds. The most researched seaweed polyphenol class is the phlorotannins, which are specifically synthesized by brown seaweeds, but there are other polyphenolic compounds, such as bromophenols, flavonoids, phenolic terpenoids, and mycosporine-like amino acids. The compounds already discovered and characterized demonstrate a full range of bioactivities and potential future applications in various industrial sectors. This review focuses on the extraction, purification, and future applications of seaweed phenolic compounds based on the bioactive properties described in the literature. It also intends to provide a comprehensive insight into the phenolic compounds in seaweed.

RESUMO

INTRODUCTION: Differences in dietary intake and physical activity may explain the higher prevalence of obesity among adolescents living in rural versus urban settings. The objective of this cross-sectional secondary analysis was to compare baseline dietary intake and physical activity of adolescents by rurality. METHODS: We analyzed data on 940 adolescents who participated in ACTION PAC (Adolescents Committed to Improvement of Nutrition and Physical Activity), an obesity prevention and management intervention trial conducted from 2014 through 2017 in 8 public high schools in the southwestern United States. Dietary intake was assessed with the Block Food Screener, and participants completed an exercise log and wore an accelerometer to provide data on physical activity. We compared data by rural-urban commuting area (RUCA) codes and log population density by using multilevel models, with students nested within zip code and repeated measures for accelerometer analysis. RESULTS: After adjusting for socioeconomic status and ethnicity, accelerometer data indicated that moderate-to-vigorous physical activity was 8.17 min/d (P = .02) higher and sedentary time was 20.42 min/d (P = .02) lower in moderately urban areas than in the urban reference area. Each 1-unit increase in log population density was associated with higher reported intake of whole grains (0.02 ounce equivalents, P = .03), potatoes (0.01 cup equivalents, P = .02), and added sugar (0.37 tsp, P = .02) after adjusting for socioeconomic status and ethnicity. CONCLUSION: Differences in reported dietary intake and physical activity level by measures of rurality were small and inconsistent in direction to explain the disparities observed in rural versus urban areas.

RESUMO

Mortality from collision with vehicles is the most visible impact of road traffic on wildlife. Mortality due to roads (hereafter road-kill) can affect the dynamic of populations of many species and can, therefore, increase the risk of local decline or extinction. This is especially true in Brazil, where plans for road network upgrading and expansion overlaps biodiversity hotspot areas, which are of high importance for global conservation. Researchers, conservationists and road planners face the challenge to define a national strategy for road mitigation and wildlife conservation. The main goal of this dataset is a compilation of geo-referenced road-kill data from published and unpublished road surveys. This is the first Data Paper in the BRAZIL series (see ATLANTIC, NEOTROPICAL, and BRAZIL collections of Data Papers published in Ecology), which aims make public road-kill data for species in the Brazilian Regions. The dataset encompasses road-kill records from 45 personal communications and 26 studies published in peer-reviewed journals, theses and reports. The road-kill dataset comprises 21,512 records, 83% of which are identified to the species level (n = 450 species). The dataset includes records of 31 amphibian species, 90 reptile species, 229 bird species, and 99 mammal species. One species is classified as Endangered, eight as Vulnerable and twelve as Near Threatened. The species with the highest number of records are: Didelphis albiventris (n = 1,549), Volatinia jacarina (n = 1,238), Cerdocyon thous (n = 1,135), Helicops infrataeniatus (n = 802), and Rhinella icterica (n = 692). Most of the records came from southern Brazil. However, observations of the road-kill incidence for non-Least Concern species are more spread across the country. This dataset can be used to identify which taxa seems to be vulnerable to traffic, analyze temporal and spatial patterns of road-kill at local, regional and national scales and also used to understand the effects of road-kill on population persistence. It may also contribute to studies that aims to understand the influence of landscape and environmental influences on road-kills, improve our knowledge on road-related strategies on biodiversity conservation and be used as complementary information on large-scale and macroecological studies. No copyright or proprietary restrictions are associated with the use of this data set other than citation of this Data Paper.

RESUMO

The association between selective serotonin reuptake inhibitor (SSRI) use and bone mass density (BMD) has been debated. Inadequate diet, which may occur in depressed individuals prescribed SSRIs is also associated with decreased BMD. This study seeks to determine if SSRI use in adults is associated with lower than average BMD while controlling for nutrition related variables. Further, it investigates whether there are potential interactions between micronutrients and SSRI use on BMD. Adults, 655 with an SSRI prescription ≥180 days and 12,372 non-users, were identified in the 2005-2014 National Health and Nutrition Examination Survey (NHANES) data. Survey respondents were propensity score matched on propensity to have an SSRI prescription and compared on femoral neck BMD t-scores. A sub-analysis within SSRI users was conducted to calculate the odds ratio (OR) of having a low (osteopenia or osteoporosis) BMD t-score given SSRI exposure and inadequate daily micronutrient intake. Inadequate daily micronutrient intake was common; over half of SSRI users and non-users had inadequate calcium, vitamin D, and potassium. SSRI use was associated with an absolute reduction of 0.11 in BMD t-score. Inadequate daily vitamin D intake was associated with lower BMD t-scores in both SSRI users and non-users. The interaction of SSRI use and inadequate daily intake of zinc was also associated with low BMD (OR: 1.11, 95% CI: 1.01-1.23). Patient health may be improved by nutritional education, referral to a dietitian, or by micronutrient monitoring by the prescribing physician.

RESUMO

Background The ductus venosus agenesis (DVA) is a rare condition with a variable prognosis that relies partly on the presence of associated conditions. The purpose of our study was to analyze the literature regarding the post-natal outcome of fetuses with DVA associated with fetal malformations, in order to discuss the best management options for couples. Methods We performed a systematic review of the literature of MEDLINE and SCOPUS electronic databases in a 25-year period from 1992 to September 2017. Methods We found 340 cases of DVA associated with fetal abnormalities. The most common chromosomal abnormalities were: monosomy X (12/48, 25%), trisomy 21 (11/48, 22.9%) and trisomy 18 (6/48, 12.5%). From the 340 cases with DVA, in 31 cases the umbilical venous shunt type was not reported. Of the fetuses, 60.8% (188/309) had an extrahepatic umbilical venous drainage while 39.2% (121/309) presented an intrahepatic connection. The DVA was associated in 71 cases (23.0%) with cardiac abnormalities, in 82 cases (26.5%) with extracardiac abnormalities and in 85 cases (27.5%) with both cardiac and extracardiac abnormalities. Conclusion DVA associated with both cardiac and extracardiac malformations may confer a poorer fetal outcome, a clinically relevant fact that should clarify what can be expected from this entity and help prenatal counseling.

RESUMO

A life cycle-based model, OSTUM (Oil Sands Technologies for Upgrading Model), which evaluates the energy intensity and greenhouse gas (GHG) emissions of current oil sands upgrading technologies, is developed. Upgrading converts oil sands bitumen into high quality synthetic crude oil (SCO), a refinery feedstock. OSTUM's novel attributes include the following: the breadth of technologies and upgrading operations options that can be analyzed, energy intensity and GHG emissions being estimated at the process unit level, it not being dependent on a proprietary process simulator, and use of publicly available data. OSTUM is applied to a hypothetical, but realistic, upgrading operation based on delayed coking, the most common upgrading technology, resulting in emissions of 328 kg CO2e/m3 SCO. The primary contributor to upgrading emissions (45%) is the use of natural gas for hydrogen production through steam methane reforming, followed by the use of natural gas as fuel in the rest of the process units' heaters (39%). OSTUM's results are in agreement with those of a process simulation model developed by CanmetENERGY, other literature, and confidential data of a commercial upgrading operation. For the application of the model, emissions are found to be most sensitive to the amount of natural gas utilized as feedstock by the steam methane reformer. OSTUM is capable of evaluating the impact of different technologies, feedstock qualities, operating conditions, and fuel mixes on upgrading emissions, and its life cycle perspective allows easy incorporation of results into well-to-wheel analyses.

RESUMO

Nonalcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease in children and adolescents. The goal of this study was to describe the demographic, anthropometric and biochemical data of children and adolescents diagnosed with NAFLD during a seven-year period in an outpatient pediatric clinic in the Southwest region of the US and to evaluate relationships between race, BMI, ALT, triglyceride levels, age and gender with a diagnosis of NAFLD. A retrospective medical record review of patients who attended an outpatient pediatric clinic with a billing diagnosis ICD-9 code of 571.8 was conducted. Forty-one patients met these criteria. The majority was male (74%) Hispanic (32%), Hispanic/Latino (68%) and obese. The small number of patients diagnosed with NAFLD in our study is consistent with previously reported results. Our results indicate that the population of this culturally diverse, high-risk population has significant clinical markers that are indicative of NAFLD.

RESUMO

This study aimed to assess the degree of contamination of bulk tank milk (BTM) by Staphylococcus spp. and coliform bacteria and to identify major milking practices that help perpetuate them in dairy cattle herds in São Miguel Island. In July 2014, BTM was sampled and a survey concerning local milking practices was conducted on 100 herds. Semi quantitative multiplex polymerase chain reaction detected coagulase-negative staphylococci, Escherichia coli, Staphylococcus aureus, and other coliform bacteria (Klebsiella oxytoca, Klebsiella pneumoniae, and Serratia marcescens) in 100, 75, 59, and 35 % of BTM, respectively. According to multivariable univariate models, on herds not using hot water for cleaning the milking machine and teat liners, there was at least 3.4 more odds (P < 0.01) to have S. aureus or coliform bacteria contamination in BTM. The likelihood of finding S. aureus in BTM was higher (P < 0.001) on herds without high hygiene during milking, when milking mastitic cows at the end, on abrupt cessation of milking at dry-off, and official milk control implementation. The glove use also favored (odds ratio (OR) 5.8; P < 0.01) the detection of coliform bacteria in BTM. Poor milking practices identified in this study should be avoided in order to decrease S. aureus and coliform bacteria contamination of BTM. Other factors associated with milk quality in São Miguel Island also should be further investigated.

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

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

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

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

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

OBJECTIVE: The purpose of this review was to analyze, based on a review of the current literature, the effects of physical activity on the quality of life (QoL) of subjects with asthma. METHODS: The authors conducted a search of randomized controlled trials (RCTs) between January 2000 and August 2010 in a group of major databases of health sciences (Academic Search Complete, Directory of Open Access Journals, Elsevier--Science Direct, Highwire Press, PubMed, Scielo Global, Scirus, Scopus, SpringerLink, Taylor & Francis, and Wiley Interscience) with the keywords asthma, QoL, physical activity, exercise, training, and program in all possible combinations. Citations and references of each study selected were also examined. RESULTS: Of the 1075 studies identified, only 11 were included. Five of these studies were performed in children between the ages of 7 and 15 and the remaining studies were performed on adults. Intervention programs were divided into aerobic training programs and breathing exercises programs. All aerobic training programs showed improvements in QoL, demonstrating a positive influence of aerobic training on asthma. CONCLUSIONS: There is a noticeable trend in the benefit of aerobic training programs in the QoL for individuals with asthma. The breathing exercises programs were few and heterogeneous, making it difficult to reach a positive conclusion on whether it could be recommended for the improvement of QoL in this pathology. There is a great need for more RCTs with methodological rigor.

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.
