RESUMO

Introducción. El perímetro cefálico (PC) es un indicador del crecimiento cerebral y es necesario contar con referencias de crecimiento que permitan determinar variaciones normales o patológicas. Objetivos. Presentar las primeras referencias argentinas de perímetro cefálico entre el nacimiento y los 19 años, y compararlas con las referencias de Nellhaus, utilizadas en nuestro país hasta la actualidad. Población y métodos. Para la construcción de estas referencias, se combinaron datos de la Encuesta Nacional de Nutrición y Salud 2018 y estudios transversales realizados entre 2004 y 2007 en las provincias de Buenos Aires y La Pampa, que incluyeron 8326 niños, niñas y adolescentes sanos. Las curvas de crecimiento fueron ajustadas con el método LMS. Para evaluar la magnitud de las diferencias entre estas referencias y las de Nellhaus, a diferentes edades, se graficaron los centilos 2, 50 y 98. Resultados. El PC mostró un incremento de tamaño variable con la edad, de mayor magnitud en los primeros años de vida, y un ligero incremento en la pubertad. Los valores del centilo 98 de las referencias argentinas fueron mayores que los de Nellhaus en todas las edades. Los valores del centilo 2 de la referencia nacional fueron menores que los de Nellhaus durante los primeros 2 años de vida, similares entre los 3 y 7 años, y mayores a partir de esta edad. Conclusiones. Las curvas argentinas describen adecuadamente el patrón de crecimiento del PC. Las diferencias halladas con la referencia de Nellhaus pueden atribuirse a cambios seculares.

Introduction. Head circumference (HC) is an indicator of brain growth; growth charts are necessary to determine normal or pathological variations. Objectives. To present the first Argentine HC reference charts between birth and 19 years of age and to compare them with the Nellhaus charts, which have been used in our country to date. Population and methods. These references were developed based on combined data from the National Survey on Nutrition and Health of 2018 and cross-sectional studies conducted between 2004 and 2007 in the provinces of Buenos Aires and La Pampa, which included 8326 healthy children and adolescents. Growth curves were adjusted using the LMS method. To assess the differences between these reference charts and the Nellhaus charts, at different ages, the 2nd, 50th, and 98th percentiles were plotted. Results. HC showed a variable increase in size with age, which was greater in the first years of life, and a slight increase at puberty. The values for the 98th percentile of the Argentine reference charts were higher than those of the Nellhaus charts at all ages. The values for the 2 nd percentile of the national reference were lower than those of the Nellhaus charts during the first 2 years of life, similar between 3 and 7 years of age, and higher after this age. Conclusions. The Argentine curves adequately describe the growth pattern of HC. The differences found with the Nellhaus charts may be attributed to secular changes.

RESUMO

The diversity of sustainable certifications raises questions about the credibility, intentions, and impacts of Voluntary Sustainability Standards (VSS) on Global Value Chains (GVC). Few studies show the impacts of VSS on different sustainable dimensions in sectors such as the non-timber forest product (NTFP) sector. This paper aims to investigate in the value chain of the most important NTFP in the Amazon, açaí, whether VSS contributes to sustainable outcomes in the Governance, Environmental, Economic, and Social dimensions. Using case studies in enterprises of the açaí chain and the use of tools and indicators was possible to generate information that is currently scarce for NTFPs in the Amazon from the VSS perspective. The results show that there is a great distance that the weakest links of the GVC (Micro, Small, and Medium Enterprises - MSMEs) must walk to adopt VSS and be inserted into the global market. The requirements are based on bureaucratic management activities, which are extraordinarily complex and involve many issues and indicators. The VSS lacks supplements that evaluate and validate the results reported by the companies as sustainable. Finally, the VSS is still far from ensuring an inclusive and fully sustainable chain by itself.

RESUMO

Cattle ranching is a fundamental economic activity in northern Peru, where proper management of water resources is crucial. This study, a pioneer in the region, evaluated water quality and its suitability for human consumption, vegetable irrigation, and livestock production. It is also the first study to document the presence of metals and metalloids in vulnerable areas because they are located at the headwaters of river watersheds. The spatiotemporal evaluation of physicochemical parameters, metals, and metalloids was performed in five micro-watersheds (Cabildo, Timbambo, Pomacochas, Atuen, and Ventilla) from water samples collected in the dry season (October 2017) and wet season (March 2018). The parameters were analyzed using microwave plasma atomic emission spectrometry. The results were contrasted with international and Peruvian quality standards related to dairy cow production. The highest values of pH, total dissolved solids, and electrical conductivity were reported during the dry season, and the highest turbidity during the wet season. Of the metals evaluated, arsenic (As) was omnipresent in all the micro-watersheds, followed by lead (Pb). In contrast to World Health Organization regulations, concentrations of As, cadmium (Cd), Pb, and iron represent a risk; according to Peruvian regulations, As and Pb exceed the concentrations established for use in animal drinking water and vegetable irrigation, and according to water guidelines for dairy cattle, concentrations of As, Pb, Cd, and Al exceed the permitted limits. The high concentrations of these metals in the study area are attributable to a synergy between natural factors, such as Andean geology and livestock activity. The data reported will allow for proper water resource management, pollution prevention, and the design and adoption of mitigation measures.

RESUMO

BACKGROUND: Clinical practice guidelines (CPGs) are statements to assist practitioners and stakeholders in decisions about healthcare. Low methodological quality guidelines may prejudice decision-making and negatively affect clinical outcomes in non-communicable diseases, such as cardiovascular diseases worsted by poor lipid management. We appraised the quality of CPGs on dyslipidemia management and synthesized the most updated pharmacological recommendations. METHODS: A systematic review following international recommendations was performed. Searches to retrieve CPG on pharmacological treatments in adults with dyslipidaemia were conducted in PubMed, Scopus, and Trip databases. Eligible articles were assessed using AGREE II (methodological quality) and AGREE-REX (recommendation excellence) tools. Descriptive statistics were used to summarize data. The most updated guidelines (published after 2019) had their recommendations qualitatively synthesized in an exploratory analysis. RESULTS: Overall, 66 guidelines authored by professional societies (75%) and targeting clinicians as primary users were selected. The AGREE II domains Scope and Purpose (89%) and Clarity of Presentation (97%), and the AGREE-REX item Clinical Applicability (77.0%) obtained the highest values. Conversely, guidelines were methodologically poorly performed/documented (46%) and scarcely provided data on the implementability of practical recommendations (38%). Recommendations on pharmacological treatments are overall similar, with slight differences concerning the use of supplements and the availability of drugs. CONCLUSION: High-quality dyslipidaemia CPG, especially outside North America and Europe, and strictly addressing evidence synthesis, appraisal, and recommendations are needed, especially to guide primary care decisions. CPG developers should consider stakeholders' values and preferences and adapt existing statements to individual populations and healthcare systems to ensure successful implementation interventions.

RESUMO

The Research Ethics Committee (CEP) has become an essential mechanism for social control in Brazilian research involving human subjects, contributing to the development of studies guided by ethical standards and to the protection of research participants. This article analyzes the performance of CEP in Western Amazonian institution, its history, operating conditions, trends, and different aspects between 2018 to 2022. The theoretical framework addresses the history of research involving human subjects, the origins and evolution of bioethics in the international context, bioethics in Brazil, and regulations on the ethical analysis of research. The data were collected through the Brazil Platform and reports from the institution's CEP. The CEP evaluated 865 research protocols, most of which were from Health Sciences. Additionally, it was observed that during 2018 to 2022 the covid-19 pandemic had a negative impact on the number of projects submitted for evaluation to the CEP. The 57% drop in the number of projects registered during 2020/2022 reveals the negative impact of this event on the execution of projects with human participants.

RESUMO

This study investigated how a standard could become reality-based in a workplace where certain types of deviations are not permitted, such as a radiopharmaceutical production unit. Compliance with standards is necessary to ensure the safety of individuals who manufacture such substances as well as the security of patients receiving treatment. In this qualitative case study, an ergonomic analysis of work (also known as activity analysis) was performed, with noncompliance recorded in internal audits as a starting point: the lack of double-checking in radiopharmaceutical synthesis cassette assembly. Field observations and self-confrontation interviews with workers from a production unit were conducted to analyze the activities. Although a double-check did not occur, the radiopharmaceutical synthesis operator apparently developed another risk control strategy, focusing his attention to the equipment assembly details, which necessitated continuous control and verification actions to ensure that there were no problems at this stage of production. A multilevel approach was used to demonstrate how the safety and quality of production processes based on standard compliance only become effective and adherent to the activity after resolving various conflicts at work, including control systems (external and internal audits), work collectives, the contradiction of the activity itself, and the discussion of singular situations arising daily. This study contributes to the discussion on workplace safety considering standardization and advances the discussion on changing perspectives regarding rule compliance.

RESUMO

The objective of this study is to compare and contrast the quality statements and quality indicators across clinical care standards for low back pain. Searches were performed in Medline, guideline databases, and Google searches to identify clinical care standards for the management of low back pain targeting a multidisciplinary audience. Two independent reviewers reviewed the search results and extracted relevant information from the clinical care standards. We compared the quality statements and indicators of the clinical care standards to identify the consistent messages and the discrepancies between them. Three national clinical care standards from Australia, Canada, and the United Kingdom were included. They provided from 6 to 8 quality statements and from 12 to 18 quality indicators. The three standards provide consistent recommendations in the quality statements related to imaging, and patient education/advice and self-management. In addition, the Canadian and Australian standards also provide consistent recommendations regarding comprehensive assessment, psychological support, and review and patient referral. However, the three clinical care standards differ in the statements related to psychological assessment, opioid analgesics, non-opioid analgesics, and non-pharmacological therapies. The three national clinical care standards provide consistent recommendations on imaging and patient education/advice, self-management of the condition, and two standards (Canadian and Australian) agree on recommendations regarding comprehensive assessment, psychological support, and review and patient referral. The standards differ in the quality statements related to psychological assessment, opioid prescription, non-opioid analgesics, and non-pharmacological therapies.

RESUMO

Rats and mice are the most used experimental models in research. Globally, animal houses are subjected to parasite outbreaks. In Brazil, the parasitological profile is used to reflect the sanitary condition of laboratory animals and must be monitored frequently. The present study developed an integrative review of scientific studies on the parasitological profile of rats and mice in animal facilities in Brazil. It identified the most prevalent parasite species reported in animal facilities from different geographic regions of the country, as well as factors contributing to the perpetuation of these parasites, and proposed measures to help prevent such infections. Based on the guiding question "which endoparasites and ectoparasites have already been identified in rat and mouse colonies in animal facilities in Brazil?" and considering inclusion and exclusion criteria, 28 studies published between 1974 and 2021 were selected in four scientific bases. These studies covered facilities in 12 Brazilian States, describing 16 genera of parasites in mice and 18 in rats. Most of the facilities in the selected studies were of the conventional type and with few sanitary barriers, and these conditions may favor the recurrence of parasites. Efforts are, therefore, necessary for institutions to have animal facilities in accordance with the legislation and practice optimal methodologies. The measures proposed in this article can contribute to change the panorama of parasites in the national animal facilities, aiming to safeguard the quality of scientific data and animal welfare.

Ratos e camundongos são os modelos experimentais mais utilizados em pesquisa. Globalmente, as instalações de animais estão sujeitas a surtos de parasitas. No Brasil, o perfil parasitológico é utilizado para refletir a condição sanitária dos animais de laboratório e deve ser monitorado frequentemente. O presente estudo teve como objetivo desenvolver uma revisão integrativa de estudos científicos sobre o perfil parasitológico de ratos e camundongos em biotérios no Brasil. A revisão identifica as espécies parasitárias mais prevalentes relatadas em biotérios de diferentes regiões geográficas do país, bem como os fatores que contribuem para a perpetuação desses parasitas, e propõe medidas para ajudar a prevenir tais infecções. Com base na questão norteadora "quais endoparasitas e ectoparasitas já foram identificados em colônias de ratos e camundongos em biotérios no Brasil?" e considerando os critérios de inclusão e exclusão, foram selecionados 28 estudos publicados entre 1974 e 2021 em quatro bases científicas. Esses estudos abrangeram instalações em 12 estados brasileiros, descrevendo 16 gêneros de parasitas em camundongos e 18 em ratos. A maioria das instalações dos estudos selecionados era do tipo convencional e com poucas barreiras sanitárias, e essas condições podem favorecer a recorrência de parasitas. Portanto, esforços são necessários para que as instituições tenham biotérios de acordo com a legislação e pratiquem metodologias otimizadas. As medidas propostas neste artigo podem contribuir para mudar o panorama das parasitoses nos biotérios nacionais, visando salvaguardar a qualidade dos dados científicos e o bem-estar animal.

RESUMO

Abstract Background In 2012, the Neurocritical Care Society launched a compilation of protocols regarding the core issues that should be addressed within the first hours of neurological emergencies - the Emergency neurological life support (ENLS). Objective We aim to evaluate this repercussion through a bibliometric analysis. Methods We searched Scopus on October 2022 for articles mentioning ENLS. The following variables were obtained: number of citations; number of citations per year; number of publications per year; year of publication; research type; research subtype; country of corresponding author and its income category and world region; journal of publication and its 5-year impact factor (IF); and section where ENLS appeared. Results After applying eligibility criteria, we retrieved 421 articles, published from 2012 to 2022. The mean number of citations per article was 17.46 (95% Confidence Interval (CI) = 8.20-26.72), while the mean number of citations per year per article was 4.05 (95% CI = 2.50-5.61). The mean destiny journal 5-year IF was 5.141 (95% CI = 4.189-6.093). The majority of articles were secondary research (57.48%; n= 242/421) of which most were narrative reviews (71.90%; n= 174/242). High-Income countries were the most prominent (80.05%; n= 337/421 articles). There were no papers from low-income countries. There were no trials or systematic reviews from middle-income countries. Conclusion Although still low, the number of publications mentioning ENLS is increasing. Articles were mainly published in journals of intensive care medicine, neurology, neurosurgery, and emergency medicine. Most articles were published by authors from high-income countries. The majority of papers were secondary research, with narrative review as the most frequent subtype.

RESUMO

Abstract This paper examines how variations in the height and health of Mexicans during the second half of the twentieth century reflect the evolution of economic inequality, as its effects have repercussions on the health and nutritional conditions of the population. The average height of Mexican adults had a modest increase with respect to the possibilities of human plasticity. These anthropometric variations were the result of the incorporation of advances in science and technology leading to improved standards of living among the population. Body changes were impacted by dietary habits, urbanization, and government policies supporting food production and distribution.

Resumen Este trabajo examina cómo las variaciones en la estatura y la salud de los mexicanos durante la segunda mitad del siglo XX son un reflejo de la evolución de la desigualdad económica pues sus efectos repercuten en las condiciones de salud y alimentación de la población. La estatura promedio de adultos mexicanos tuvo un aumento modesto con respecto a las posibilidades de la plasticidad humana. Estas variaciones antropométricas fueron resultado de la incorporación de avances en ciencia y tecnología conducentes a mejorar los niveles de vida de la población. Los cambios corporales fueron impactados por hábitos alimenticios, de urbanización y políticas gubernamentales de apoyo a la producción y distribución de alimentos.

RESUMO

Introducción: la gastrosquisis congénita (GC) es una patología con creciente demanda asistencial. Atentos a esto, en el Centro Hospitalario Pereira Rossell (CHPR) se implementó un protocolo de cuidados llevado adelante por un equipo multidisciplinario. En este trabajo nos proponemos evaluar el impacto en la sobrevida y morbilidad a partir de su aplicación. Material y método: estudio comparativo tipo antes y después de pacientes portadores de GC (n = 47), 29 de una cohorte histórica (GH) y 18 de una cohorte posaplicación de protocolo (GP). Con edad gestacional ≥ 36 semanas y peso al nacer ≥ 2500 g, asistidos en el CHPR entre los años 2016 y 2021. Resultados: no se observaron diferencias perinatales entre ambos grupos, ni en la incidencia de GQ complicadas. En el GP se observó mayor incidencia de cierre abdominal precoz (p < 0,01), menor necesidad de realización de silo quirúrgico (p < 0,01), menor tiempo de administración de ventilación mecánica (p = 0,03), de uso total de opioides (p < 0,01), de administración de nutrición parenteral (p = 0,03), e inicio más temprano de la alimentación enteral (p = 0,03). Sin diferencias en la sobrevida al egreso hospitalario. Conclusiones: la aplicación de un protocolo estandarizado se asoció a una reducción significativa en el tiempo de cierre abdominal, de ventilación mecánica, nutrición parenteral y de opioides, con inicio más precoz de la nutrición enteral.

Introduction: congenital gastroschisis is an increasingly demanded pathology, therefore a care protocol was implemented at the Pereira Rossell Pediatric Hospital (CHPR), and it has been carried out by a multidisciplinary team. In this paper, we aim at assessing the morbidity and mortality impact of survival and morbidity of this application. Materials and Methods: comparative before and after study of a historical cohort (GH, n=29) versus a post-protocol application cohort (GP, n=18), in patients with a gestational age ≥36 weeks and birth weight ≥2500 grams assisted in CHPR between 2016-2021. Results: no perinatal differences were observed between both groups or in the incidence of complicated GQ. In the GP, a higher incidence of early abdominal closure was decreased (GH 3.4% vs GP 67%, p<0.01), less need to perform a surgical silo (GH 100% vs GP 33%, p<0.01 ), shorter mechanical ventilation administration time (GH 2 days vs GP 0.5 days, p=0.03), total use of opioids (GH 3.5 days vs GP 7 days, p<0.01) , of administration of parenteral nutrition (GH 24.5 days vs GP 20 days, p=0.03), and earlier start of enteral feeding (GH 11 days vs GP 7 days, p=0.03). No differences in survival after hospital discharge (93% vs 89%, p=0.63). Conclusions: the application of a standardized protocol was linked to a significant reduction in the time of abdominal closure, mechanical ventilation, parenteral nutrition, and opioids, with earlier initiation of enteral nutrition.

Introdução: a gastrosquise congênita (GC) é uma patologia com demanda crescente de atendimento e, porém, foi implementado um protocolo de atendimento por equipe multidisciplinar no Centro Hospitalar Pediátrico Pereira Rossell (CHPR). Neste trabalho propomos avaliar o impacto na mortalidade e morbidade depois de sua aplicação. Material e Métodos: estudo comparativo antes e depois de pacientes com CG (n=47), sendo 29 de uma coorte histórica (GH) e 18 de uma coorte pós-aplicação de protocolo (GP). Idade gestacional ≥ 36 semanas e peso ao nascer ≥ 2.500 gramas atendidos no CHPR entre os anos de 2016-2021. Resultados: não foram observadas diferenças perinatais entre os dois grupos ou na incidência de QG complicada.

RESUMO

BACKGROUND: Since 2020 in Mexico, front-of-pack warning labels (FOPWL) have been implemented in processed products. Evidence supports warning labels allow consumers to identify unhealthy products. We aimed to evaluate the hypothetical impact of the FOPWL regulation on the Mexican population's intake of critical nutrients and energy, based on the replacement of food and beverages using 4 hypothetical scenarios which represented the phases of the regulation. METHODS: Dietary data were collected using a standardized 24-h dietary recall from the 2016 Mexican National Health and Nutrition Survey (n = 4184). To evaluate the hypothetical impact of FOPWL, the nutritional content of critical nutrients in processed products was evaluated according to the Mexican Official Standard 051 (NOM-051). Then, we replaced products with several warning labels (WL) with those with a fewer number of them or with non-processed food. For the replacement, 4 hypothetical scenarios were established: scenario 1: the current consumption of the Mexican Population, scenario 2: the replacement during the first phase of the norm, scenario 3: the replacement in the second phase and scenario 4: the replacement in the last phase. We estimated the means, confidence intervals (CI 95%), and the mean percentage change of energy, saturated fat, trans-fat, added sugars, and sodium intake during the second, third, and the fourth scenarios. RESULTS: According to the norm, in the second scenario, the majority of the products presented a label for energy (52.6%) whereas in the third (56.4%) and fourth (61.2%) scenarios were for sodium. In contrast, trans-fat was the least labeled nutrient in all the scenarios (from 2.1 to 4.1%). In the fourth scenario, we observed a reduction of the intake of energy intake to 15.4% as well as saturated fat (- 20%, CI 95% - 18.4; - 21.6), trans-fat (- 8.2%, CI 95% - 6.4; - 10.1) and sodium (- 12.7%, CI 95% - 11.3; - 14.1). The most important reduction was observed for added sugars intake (until - 54.1%, CI 95% - 51; - 57.1). CONCLUSIONS: FOPWL could be an effective strategy to decrease energy consumption and nutrients of concern. If consumers use the FOPWL, it would be an important change in critical nutrients intake. These results support that FOPWL might help the Mexican population to choose healthier nutrition alternatives.

RESUMO

Background: The creation of computer-supported collaborative clinical cases is an area of educational research that has been widely studied. However, the reuse of cases and their sharing with other platforms is a problem, as it encapsulates knowledge in isolated platforms without interoperability. This paper proposed a workflow ecosystem for the collaborative design and distribution of clinical cases through web-based computing platforms that (1) allow medical students to create clinical cases collaboratively in a dedicated environment; (2) make it possible to export these clinical cases in terms of the Health Level 7 (HL7) Fast Healthcare Interoperability Resources (FHIR) interoperability standard; (3) provide support to transform imported cases into learning object repositories; and (4) use e-learning standards (eg, Instructional Management Systems Content Packaging [IMS-CP] or Sharable Content Object Reference Model [SCORM]) to incorporate this content into widely-used learning management systems (LMSs), letting medical students democratize a valuable knowledge that would otherwise be confined within proprietary platforms. Objective: This study aimed to demonstrate the feasibility of developing a workflow ecosystem based on IT platforms to enable the collaborative creation, export, and deployment of clinical cases. Methods: The ecosystem infrastructure for computer-supported collaborative design of standardized clinical cases consists of three platforms: (1) Mosaico, a platform used in the design of clinical cases; (2) Clavy, a tool for the flexible management of learning object repositories, which is used to orchestrate the transformation and processing of these clinical cases; and (3) Moodle, an LMS that is geared toward publishing the processed clinical cases and delivering their course deployment stages in IMS-CP or SCORM format. The generation of cases in Mosaico is exported in the HL7 FHIR interoperability standard to Clavy, which is then responsible for creating and deploying a learning object in Moodle. Results: The main result was an interoperable ecosystem that demonstrates the feasibility of automating the stages of collaborative clinical case creation, export through HL7 FHIR standards, and deployment in an LMS. This ecosystem enables the generation of IMS-CPs associated with the original Mosaico clinical cases that can be deployed in conventional third-party LMSs, thus allowing the democratization and sharing of clinical cases to different platforms in standard and interoperable formats. Conclusions: In this paper, we proposed, implemented, and demonstrated the feasibility of developing a standards-based workflow that interoperates multiple platforms with heterogeneous technologies to create, transform, and deploy clinical cases on the web. This achieves the objective of transforming the created cases into a platform for web-based deployment in an LMS.

RESUMO

In Brazil, scarce air quality data hinders air pollutant chemical understanding and policy decisions regarding public health and environmental impacts. From this perspective, our study assessed the O3, PM2.5, and PM10 yearly and seasonal trends and also the WHO Air Quality Guidelines 2021 exceedance trends at 40 air quality stations located in four highly urbanized zones in Brazil (Belo Horizonte, São Paulo, Rio de Janeiro, and Espírito Santo) from early 1990s up to 2019. We applied the Mann-Kendall test aligned with Sen's Slope estimator to assess the trends and the Cox-Stuart test to verify the WHO AQG 2021 exceedances trends. Our findings pointed out that the current national legislation is outdated when compared to WHO AQG 2021 values, leading to multiple exceedances episodes. We also found out that 62% of São Paulo's stations presented O3 increasing trends, while in Rio de Janeiro 85.7% presented decreasing trends. The Cox-Stuart test pointed out that PM2.5 exceedance trends showcase positive values, and most of the significative values are located in São Paulo stations. Therefore, we endorse that the national legislation needs to be updated meanwhile the air monitoring network needs to expand its coverage.

RESUMO

Metal contamination associated with mining activities has been considered one of the main environmental pollution problems in the Amazon region. Understanding the levels of metal contamination from mining activities requires a good understanding of background metal concentrations, which may vary notably according to the geology/lithology characteristics of the region, soil type, and predominant biogeochemical processes. This review assessed 50 papers and reports published between 1989 and 2020 describing environmental concentrations of different metals and metalloids (As, Hg, Mn, Fe, Cd, Cu, Cr, Pb, Ni, and Zn) in water and sediments of mining and non-mining areas in five geographic regions of the Amazon basin. Metal enrichment caused by mining activities was calculated and exposure concentrations were compared with sediment and water quality standards set for the protection of aquatic life. Significant enrichments of Cd, Cu, Cr, Fe, Hg, Mn, Ni and Zn were observed in mining areas in both sediment and water. Regarding background levels in the different geographic regions, the highest prevalence of metal enrichment (i.e., concentrations 10 to 100-fold higher than mean background values) in sediment samples was found for Fe (100% of samples), Ni (90%), and Mn (69%). For water, high prevalence of metal enrichment occurred for Zn, Mn, and Fe (100% of samples), and for Hg (86%). Hg, Fe, Pb, Cu, Cd, Ni and Zn exceeded water and/or sediment quality standards in a significant number of samples in the proximity of mining areas. This study indicates that mining activities significantly contribute to water and sediment contamination across the Amazon basin, posing hazards for freshwater ecosystems and potentially having human health implications.

RESUMO

BACKGROUND: Pandemics with devastating morbidity and mortality have occurred repeatedly throughout recorded history. Each new scourge seems to surprise governments, medical experts, and the public. The SARS CoV-2 (COVID-19) pandemic, for example, arrived as an unwelcome surprise to an unprepared world. DISCUSSION: Despite humanity's extensive experience with pandemics and their associated ethical dilemmas, no consensus has emerged on preferred normative standards to deal with them. In this article, we consider the ethical dilemmas faced by physicians who work in these risk-prone situations and propose a set of ethical norms for current and future pandemics. As front-line clinicians for critically ill patients during pandemics, emergency physicians will play a substantial role in making and implementing treatment allocation decisions. CONCLUSION: Our proposed ethical norms should help future physicians make morally challenging choices during pandemics.
