    A urbanização faz com que passe por alterações e modificações, podendo causar a redução do tempo de concentração das águas e aumentar a sua velocidade de escoamento na bacia hidrográfica, ampliando assim as vazões máximas das bacias urbanas e produzindo maiores picos de enchentes e inundações. Isso ocorre devido à urbanização que provoca efeitos como: a impermeabilidade do solo, a canalização dos escoamentos a redução da evapotranspiração e do escoamento subterrâneo, a redução das áreas naturais de detenção e retenção das águas pluviais (AMARAL e GUTJAHR, 2012). O processo de urbanização da cidade de Parauapebas foi descontrolado, causando assim vários impactos nos recursos hídricos. A ocupação descontrolada e irregular das margens do rio, ocupação do solo de forma desordenada, destruição dos morros e o aterramento das drenagens, contribui diretamente para o encadeamento de uma série de problemas que ocorrem na cidade. Pertencente à Mesorregião Sudeste Paraense e à Microrregião de Parauapebas, a cidade é limitada ao norte pelo município de Marabá, a leste pelo município de Curionópolis, ao Sul pelos municípios de Canãa do Carajás e Água Azul do Norte e a Oeste do município de São Félix do Xingu. Este trabalho tem como objetivo geral observar as modificações na rede de drenagem da cidade de Parauapebas com ênfase nos empreendimentos que estão sendo realizados no município que podem afetar diretamente a população. E específicos, analisar a dinâmica dos rios que circulam a cidade; Observar se ocorre uma diferença do aumento do nível dos rios em períodos de maior vazão; Verificar como a população está influenciando para o agravamento das enchentes e inundações que ocorrem nesses períodos; Elaborar um mapa de risco de inundação do município de Parauapebas

    Introduction: Hashimoto's thyroiditis (HT) is an autoimmune disease that affects the thyroid gland, designated by the inflammation and destruction of thyroid tissue, triggered by the autoimmune response, which results in the production of autoantibodies, such as antithyroglobulin and antithyroperoxidase antibodies. Objective: To evaluate the pathogenesis, diagnosis and management of Hashimoto's Thyroiditis. Methodology: This is a bibliographic review that included original articles and systematic reviews in English and Portuguese, which addressed the pathogenic, diagnostic and therapeutic aspects of HT, published between 2014 and 2024, selected from the PubMed, Scopus and SciELO databases. After careful selection, 21 articles were chosen to compose this bibliographic review. Results: The pathogenesis of HT presents several relevant aspects, such as the abnormality of regulatory T cells, the exacerbated activity of Th17 cells and the increased expression of inflammatory components and pro-inflammatory cytokines. The diagnosis is made mainly by measuring TSH, free T4 and Anti-TPO, however other complementary tests may be necessary. Management is mainly associated with hormone replacement in patients with hypothyroidism. Considerations: HT is a complex condition, including multiple pathogenic mechanisms that need to be further elucidated. The diagnosis is mainly based on the serum dosage of some compounds. Pharmacological disciplines are associated with the exogenous use of thyroid hormone and surgery in some specific cases.Introdução: A tireoidite de Hashimoto (HT) é uma doença autoimune que afeta a glândula tireoide, caracterizada pela progressiva inflamação e destruição do tecido tireoidiano, desencadeada pela resposta autoimune, que resulta na produção de autoanticorpos, como os anticorpos antitireoglobulina e antitireoperoxidase. Objetivo: Avaliar a patogênese, o diagnóstico e o manejo da Tireoidite de Hashimoto. Metodologia: Trata-se de uma revisão bibliográfica que incluiu artigos originais e revisões sistemáticas em inglês e português, que abordaram os aspectos patogênicos, diagnósticos e terapêuticos da HT, publicados entre 2014 e 2024, selecionados nas bases de dados PubMed, Scopus e SciELO. Após a seleção criteriosa, foram escolhidos 28 artigos para compor esta revisão bibliográfica. Resultados: A patogênese da TH apresenta múltiplos aspectos relevantes, como a anomalia das células T reguladoras, a atividade exacerbada das células Th17 e a expressão aumentada de componentes inflamassômicos e citocinas pró-inflamatórias. O diagnóstico é realizado principalmente pela dosagem de TSH, T4 livre e Anti-TPO, porém pode ser necessário outros exames complementares. O manejo é principalmente associado à reposição hormonal em pacientes com hipotireiodismo. Considerações: A TH é uma condição complexa, incluindo múltiplos mecanismos patogênicos que precisam ser mais elucidados. O diagnóstico é baseado principalmente na dosagem sérica de alguns compostos. As intervenções farmacológicas são associadas ao uso exógeno do hormônio tireoidiano e a cirurgia em alguns casos específicos

    Transcribed sequences in the human genome can be identified with confidence only by alignment with sequences derived from cDNAs synthesized from naturally occurring mRNAs. We constructed a set of 250,000 cDNAs that represent partial expressed gene sequences and that are biased toward the central coding regions of the resulting transcripts. They are termed ORF expressed sequence tags (ORESTES). The 250,000 ORESTES were assembled into 81,429 contigs. Of these, 1,181 (1.45%) were found to match sequences in chromosome 22 with at least one ORESTES contig for 162 (65.6%) of the 247 known genes, for 67 (44.6%) of the 150 related genes, and for 45 of the 148 (30.4%) EST-predicted genes on this chromosome. Using a set of stringent criteria to validate our sequences, we identified a further 219 previously unannotated transcribed sequences on chromosome 22. Of these, 171 were in fact also defined by EST or full length cDNA sequences available in GenBank but not utilized in the initial annotation of the first human chromosome sequence. Thus despite representing less than 15% of all expressed human sequences in the public databases at the time of the present analysis, ORESTES sequences defined 48 transcribed sequences on chromosome 22 not defined by other sequences. All of the transcribed sequences defined by ORESTES coincided with DNA regions predicted as encoding exons by genscan. (http://genes.mit.edu/GENSCAN.html)

    Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set. Please cite this data paper when using its data in publications. We also request that researchers and teachers inform us of how they are using these data

    © 2021 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY-NC-ND 4.0 licenseBackground: 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods: This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. Findings: Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation: Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

    Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

    © 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. Methods: A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital. Findings: Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3·85 [95% CI 2·58–5·75]; p<0·0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63·0% vs 82·7%; OR 0·35 [0·23–0·53]; p<0·0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer. Interpretation: Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised.
