Simple Summary: Microbial pest control offers promising opportunities to develop sustainable alternatives to synthetic chemical insecticides. In Brazil, the selection of native strains of entomopathogenic fungi suggests an option for South American palm weevil (Rhynchophorus palmarum, SAPW) management and potential tools for red palm weevil (R. ferrugineus, RPW) management. Both weevils in America are susceptible to the native isolates of Beauveria bassiana, CVAD01, CVAD02, CVAD06, and CPATC/032, which originate from palm orchard soils and infected SAPW adults in northwestern Brazil's Alagoas state. The SAPW mortality rates in our study were 90 and 100% on day 21, suggesting the efficacy of these strains that are well-adapted to the environment and to the pest. We suggest both the development of formulates for microbiological insecticides against R. palmarum and future tests on R. ferrugineus. Both palm weevils, the South American (Rhynchophorus palmarum) (SAPW) and the red palm weevil (R. ferrugineus, RPW), are present in South America, affecting commercial, ornamental, and native palms. These pests oviposit and thrive on selected Arecaceae. R. palmarum mainly infests coconut (Cocos nucifera), oil palms (Elaeis guineensis), and other ornamental and native palms in America, causing a significant social impact on growers. The weevils fulfill a significant ectosymbiotic macro- and microorganism role in the first period of larval development, worsening the damage which, during this period, is not yet apparent. Palm protection in the Brazilian context suggests the use of indigenous agents for microbiological biocontrol. This research identifies three Brazilian Beauveria bassiana isolates: CVAD01, CVAD02, and CVAD06. The results suggest that the strain's impact on R. palmarum can also be compared with that of the commercial strain Beauveria bassiana. Phylogenetic analysis allowed the delimitation of species of Beauveria (Hypocreales). Pathogenicity tests caused significant mortality in R. palmarum. The isolates CVAD01, CVAD02, and CVADO6 showed high pathogenicity between 7 and 21 days, with mortality rates between 90 and 100%, suggesting that they may be effective biological control agents of R. palmarum in the field when used, within available means, to mitigate the impact of R. palmarum and R. ferrugineus in South America.

SUGAR ,HISTORY of colonies ,PLANTATIONS ,BRAZILIAN history ,EIGHTEENTH century ,SEVENTEENTH century - Abstract
The production and export of sugar defined the colonial history of Brazil. It was here that the first modern slave based plantation system was created in America. Up through the end of the 17th century it was the dominant Atlantic producer of sugar. Although production continued to grow it was replaced in world markets in the 18th century by West Indian growers and was late to modernize in the 19th and early 20th century. Yet today it is once again the world's dominant producer of sugar and the second largest producer of ethanol. How and why these changes occurred is the theme of this essay in which we explore the rise of the modern sugar and ethanol industries in Brazil. [ABSTRACT FROM AUTHOR]

The work Racism Without Racists: The Racism of Color Blindness and the Persistence of Inequality in America, written by the American sociologist Eduardo Bonilla-Silva, in 2003, and published in Brazil in 2020, is reviewed. The author focuses on the debate about "color-blind racism", defined as the style of racism predominant in American society in the post-civil rights movement era, which denies the existence of racism while preserving it under the guise of liberal ideologies. Structural racism is also discussed, according to which racism is described as part of the "normal" functioning system of racialized societies, which makes all subjects responsible for its maintenance, whether those who are openly racist or those who are silent in the face of your persistence. Thus, based on the discussions presented in the book, it is argued about its relations with "Brazilian racism", characterized by miscegenation and the myth of racial democracy, highlighting its denial.

To describe the demographic and clinical features, as well as the frequency of the HLA-B*51 allele in Behçet disease (BD) patients in Latin American countries. A systematic literature review of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines was conducted without performing a meta-analysis. We included observational studies (cross-sectional or cohort) of BD patients fulfilling the International Study Group for BD classification criteria and reported the demographic, clinical, and laboratory features of the disease in adult patients. Twelve studies were included in the SLR. Information from 532 patients across 5 Latin American countries was included for the analysis. Mean age at disease diagnosis was 33 years, 58.3% were female and 41.7% male; most patients were non-Caucasian. The most common clinical manifestations were recurrent oral ulcers and genital ulcers, followed by skin, eye, joint, neurological, gastrointestinal, vascular, and cardiac involvement. The prevalence of BD was described in 2 studies, 1 conducted in Brazil that reported a prevalence of.3/100,000 inhabitants, and another in Colombia with a prevalence of 1.1/100,000 inhabitants. The frequency of HLA-B*51 allele in BD patients was 38%, 30.1%, and 9% in Argentina, Brazil, and Mexico, respectively. The prevalence of BD in the Latin American countries seems to be low, as well as the frequency of HLA-B*51 allele. However, the strength of association between HLA-B*51 and BD remains high in our population. The key clinical features of BD are like those reported in countries/regions where BD is endemic.

Moniliasis caused by the fungus Moniliophthora roreri is one of the most destructive cacao diseases in tropical America. In 2021, the presence of the pathogen was confirmed in cacao plantations in Brazil. This is the first proteomic study of the M. roreri protein profile of ungerminated spores and mycelium compared by 2D SDS‐PAGE (Two‐dimensional gel electrophoresis) associated with mass spectrometry. A total of 446 spots were detected on ungerminated spores gels and 402 spots on M. roreri mycelial gels. A total of 29 proteins were identified from the ungerminated spores, 21 of them were exclusive, and 53 were identified in the mycelium, 16 of them were exclusive. Most of the identified proteins at both development stages were categorized as being involved in metabolic processes, reduction/oxidation processes, and protein synthesis and folding. The interaction networks observed expand the known interactions of these proteins, resulting in eight functional clusters for proteins identified in ungerminated spores and seven clusters for mycelial proteins. In addition, a biological model of ungerminated spores and mycelium with cell location of proteins was constructed. The results contribute to a better understanding of the metabolic mechanisms of M. roreri during dormancy and vegetative development, which can support future studies for strategies to control moniliasis.

The species Sciopemyia sordellii (Diptera, Phlebotominae) is widely distributed throughout the American continent. This raises doubts about their identity as a single biological entity and points to the occurrence of species complex. Here, we review the geographic distribution of S. sordellii in the Neotropical region, as well as data on its biology and ecology. Records were obtained from literature and from specimens deposited in biological collections. In total, 149 records were analysed, from 12 countries in America. However, after taxonomic revision, some specimens were wrongly identified as S. sordellii, especially those from Peru, putting in doubt the occurrence of the species in that country. In Brazil, it has been recorded in all five geographic regions and collected in different biomes, besides to other ecotypes such as caves. Furthermore, its presence in an anthropized environment has also been reported. Some studies have also diagnosed Leishmania DNA in S. sordellii, indicating that parasite circulation is being maintained between the reservoir hosts. The data evaluated in our study allowed us to provide updated information on the distribution of S. sordellii in America, which may be useful in the taxonomy of this species. [ABSTRACT FROM AUTHOR]

Xantosoma riedelianum, also called "mangarito" in Brazil, is an unconventional food plant (UFP) of the Araceae family native to tropical America. Foliar samples of the X. riedelianum showing mosaic, mottle and vein clearing symptoms were collected in the municipality of Monte Alegre (São Paulo State). Transmission electron microscope observations, mechanical transmission to experimental plants, serological (DAS-ELISA) and RT-PCR analyzes indicated that the symptoms could be associated with the presence of dasheen mosaic virus (DsMV, Potyvirus). This is the first report of DsMV in X. riedelianum in Brazil. [ABSTRACT FROM AUTHOR]

Sipha maydis (Passerini) (Hemiptera: Aphididae) is a pest of cultivated cereals and wild grasses introduced into America and first reported in South America at Argentina in 2002. In Brazil, this aphid was detected first in wheat in Oct 2006 at Rio Grande do Sul State. Between 2007 and 2013 the aphid was reported in several localities in the humid subtropical region of Brazil (southern states of Rio Grande do Sul, Santa Catarina, and Paraná) on different plant species including Triticum aestivum L., Avena strigosa Schreb., Lolium multiflorum Lam., Hordeum vulgare L., Zea mays L. (all Poaceae) and uncultivated grasses. Sipha maydis also has been captured in yellow tray traps. Peak flight activity for S. maydis occurred in the spring-summer transition and was apparently correlated with average air temperature. Sipha maydis was able to complete its life cycle on A. strigosa, L. multiflorum, H. vulgare, Z. mays, and T. aestivum. During the nymphal phase the best hosts were A. strigosa, L. multiflorum, H. vulgare, and T. aestivum. Hordeum vulgare and T. aestivum were the best for the reproductive period and longevity. The intrinsic rate of increase was greatest on A. strigosa, L. multiflorum, and T. aestivum. Generation time was longer on H. vulgare, Z. mays, and T. aestivum. Net rate reproduction was greater in H. vulgare and T. aestivum, and the finite rate of increase was greatest on A. strigosa, L. multiflorum, H. vulgare, and T. aestivum. Although the distribution of S. maydis is expanding and covering the main wheat-growing region of Brazil, and despite the wide range of hosts and the direct damage it causes to local foraging sites, aphid populations are low and their economic importance is limited. However, it reveals that S. maydis has the potential to colonize subtropical regions. Sipha maydis (Passerini) é uma praga de cereais cultivados e gramíneas silvestres introduzida na América e relatada pela primeira vez na América do Sul na Argentina em 2002. No Brasil, o pulgão-preto-dos-cereais foi detectado pela primeira vez em Triticum aestivum L. em outubro de 2006 no Estado do Rio Grande do Sul. Entre 2007 e 2013, o pulgão foi relatado em várias localidades da região subtropical húmida do Brasil (Estados da Região Sul: Rio Grande do Sul, Santa Catarina e Paraná) em diferentes espécies de plantas como T. aestivum, Avena strigosa Schreb., Lolium multiflorum Lam., Hordeum vulgare L., Zea mays L. (todas Poaceae), e gramíneas não cultivadas. Sipha maydis também foi capturado em armadilhas do tipo bandeja amarela para pulgões alados. O pico de ocorrência das formas aladas na transição primavera-verão é aparentemente correlacionado com a temperatura média do ar. S. maydis foi capaz de completar o ciclo de vida em A. strigosa, L. multiflorum, H. vulgare, Z. mays, e T. aestivum. Durante a fase de ninfa, os melhores hospedeiros foram A. strigosa, L. multiflorum, H. vulgare, e T. aestivum. A H. vulgare e o T. aestivum foram os melhores para o período reprodutivo e longevidade. A taxa intrínseca de aumento foi grande em A. strigosa, L. multiflorum, e T. aestivum; o tempo de uma geração foi mais longo em H. vulgare, Z. mays, e T. aestivum; a taxa líquida de reprodução foi ótima em H. vulgare e em T. aestivum e a taxa de aumento finito foi grande em A. strigosa, L. multiflorum, H. vulgare, e T. aestivum. Embora a distribuição de S. maydis esteja se expandindo e cobrindo a principal região tritícola do Brasil, e a despeito da ampla gama de hospedeiros e dos danos diretos que causa aos sítios de alimentação, as populações de pulgões são baixas e sua importância econômica ainda é limitada. No entanto, revela que S. maydis tem potencial para colonizar regiões subtropicais. [ABSTRACT FROM AUTHOR]

Purpose: Soccer is one of the most popular sports worldwide, a physical activity of great physiological demand and complexity. Currently, numerous trials involving physiological responses such as hypertrophy, energy expenditure, vasodilation, cardiac output, V02max, and recovery have supported the possibility of genomic predictors' affecting performance. In a complementary way to association studies with single nucleotide polymorphisms (SNPs), the objective was to evaluate if the use of population genetics data from human-genomics databases can provide information for a better understanding of the relationship between heritability and sport performance. Methods: The study included 25 healthy male professional soccer players (25.5 [4.3] y, 177.4 [6.4] cm, 76.4 [6.4] kg, body fat 10.5% [4.3%]) from the Brazilian first-division soccer club. Anthropometric measurements and field and isokinetic tests were performed to evaluate performance and physiologic parameters of subjects. Moreover, 10 genetic polymorphisms previously related to performance were genotyped. The genotypes of the same polymorphisms were obtained for 2504 individuals from the populations deposited in the 1000 Genomes database. A principal-component analysis and matrix genetic-distances approach (Fst) were evaluated. Results: As expected, the admixture Brazilian population has numerous genetic similarities with the European and American populations from genomic databases. Although the African component is absolutely recognized in genomes from the Brazilian population, using the specific performance-related SNPs, surprisingly the African population was one of the most genetically distant of the players (P < .00001). Conclusions: The early results suggest a selective pressure on genes of elite soccer players, possibly related simultaneously to physical-performance, environmental, cognitive, and sociocultural aspects.

New World capuchin monkeys are well-known by their ability to solve problems using stone tools that have the characteristics and morphology of some human-made stone tools. The aim of the present contribution is to carry out brief comparisons between the Pleistocene archeological sites from Brazil (e.g. Pedra Furada, Sitio do Meio, Vale da Pedra Furada, Toca da Tira Peia) and capuchin-made stone tool deposits. Pleistocene sites from Brazil are characterized by the exclusive use of immediately available raw material, the predominance of unifacial flaking, and abundance of cortical flakes, together with the absence of blades and bifacial thinning techniques. In all these aspects, the sites resemble capuchin-made lithic deposits and lack a number of human attributes. In sum, based on positive and negative evidence we are confident that the early archeological sites from Brazil may not be human-derived but may belong to capuchin monkeys. [ABSTRACT FROM AUTHOR]

Annonaceae is a large family composed of more than 119 genera and more than 2500 species that are distributed in both tropical and subtropical areas. The Annona genus is a member of Annonaceae family, which encompasses about 175 species, most of which are native to Brazil and tropical America. This plant is commonly found on tropical and subtropical continents. Annona atemoya is a commercially important hybrid of A. squamosa and A. cherimola. Phytochemical investigations of A. atemoya leaves, fruit, and seeds have been conducted in limited studies. The purpose of this study was to investigate the constituents of the leaves, fruit pulp, and seeds of A. atemoya because few studies have reported their constituents. Annonaceous acetogenins were identified in the leaves and pulp of A. atemoya for the first time. Twenty compounds were identified: sixteen were acetogenins and four were alkaloids. Additionally, two compounds were isolated, and their structures were confirmed by spectroscopic analysis and compared with the results of previous studies. The concentration of acetogenins in the pulp was very low compared with that in the leaves, whereas the seeds were found to contain the highest concentrations and greatest diversity of compounds.

Wild rodent species are naturally infected by Schistosoma mansoni; however, the genetic characterization of the parasite, its parasitological features, and its role in human schistosomiasis are poorly understood. In this study, we isolated and characterized Schistosoma from naturally infected Holochilus sciureus, called HS strain, collected from a schistosomiasis endemic region in Maranhão State, Brazil. To isolate the parasite, miracidia obtained from the livers of H. sciureus were used to infect Biomphalaria glabrata of sympatric (called SB) and allopatric (called BH) strains, and the produced cercariae were subcutaneously inoculated into hamsters and/or BALB/c mice. Parasitological kinetics in experimentally infected hosts were evaluated, and the tRNACys-12S (referred to as 16S herein) and cox 1 regions of mtDNA from isolated worms were amplified and sequenced. Only miracidia obtained from infected mice, but not from hamsters, were capable of infecting B. glabrata, allowing maintenance of the isolated parasite. Cox1 and 16S mtDNA sequences showed 100% similarity with S. mansoni, and phylogenetic analysis showed that the HS strain of S. mansoni forms an assemblage with isolates from America and Kenya, confirming the conspecificity. Experimental infection of B. glabrata SB with S. mansoni HS resulted in two peaks of cercariae shedding at 45 and 70 days post-infection (dpi) and caused higher mortality than in B. glabrata BH. The worm recovery rate in mice was approximately 13%, and the peak of egg elimination occurred at the 10th week post-infection. Therefore, S. mansoni obtained from H. sciureus was successfully isolated, genetically characterized, and maintained in mice, allowing further study of this schistosome strain. [ABSTRACT FROM AUTHOR]

There are nearly 7 million nursing professionals in the Region of the Americas, representing more than 56% of human health resources. The regulation of professional practices promotes and protects professional integrity, ensuring professionals are competent and well qualified. The Forum on Nursing Practice Regulation in the Region of the Americas aimed to present the regulatory frameworks for the professional practice of nursing; discuss strategic actions to support professional regulatory bodies; analyze requirements for licensing and renovating licenses; and share successful experiences in nursing regulation. The Forum counted on the participation of 83 guests in-person, with representatives from 17 countries from Latin America and the Caribbean. The COFENplay platform registered the participation of 6,906 spectators. The debates in the event led to the proposal of the following recommendations: promote a national discussion with key-actors, including the Ministries of Health, Education, and Work and Employment, to advance regulation in the countries; recommend an intersectoral articulation with the topic of Human Health Resource regulation; generate a common base for the identification of information on regulation; and broaden the research about these topics, as well as the ability to generate and analyze data.

This paper analyses some insurgent spatial practices from the indigenous movement in Brazil considering the contemporaneous conjuncture of juridical-legal offensive. Firstly, we have offered as a background a discussion about the problem of the colonial origin imposed by the modern State in what we call America, an element that is present until today in countless conflicts of territorialities in our continent and that have repercussions on current indigenous spatial practices. Afterward, we have contextualized the juridical-legal offensive in contemporary Brazil, highlighting the thesis of the marco temporal ("time frame”) still being judged in the Federal Supreme Court and the main Bills in progress in the National Congress that constitute an antiindigenous agenda. Next, we have focused on the insurgent spatial practices, notably the retomadas and self-demarcations, and, in addition, the constitution of networks and the politics of scale. In the following section, we have deepened the analysis of a territorial experience of self-demarcation related to the Munduruku Planalto people, in Santarém, western Pará. Finally, we have concluded by highlighting the limits of the logic of the modern State facing reconquest and defense of indigenous territories. [ABSTRACT FROM AUTHOR]

The prevalence of obesity around the world arises nowadays in its maximum number. Passiflora sp. genus (Passifloreace family) is native to Brazil and widely cultivated in other regions of America. The extracts of their leaves and fruits have been reported to show sedative and anxiolytic effects. Furthermore, they have been used as a medicinal plant in many populations worldwide. The Passiflora genus has been tested through in vivo studies to treat and prevent obesity and its complications. Likewise, their use as ingredients for developing probiotic foods has been increased. Therefore, the current review aimed to summarize and analyze the current knowledge about the in vivo effects of the Passiflora genus in preventing and treating obesity and overweight, following the systematic review protocol. Furthermore, an extensive review of the use of passion fruit and its by-products in the development of probiotic foods has been included. Twelve works were selected in which different Passiflora genus parts (leave, seed, fruit) have been tested as anti-obesity agents, mainly in animal male models where obesity was induced through diet. Most evidence showed that Passiflora supplementation prevents body fat accumulation and protects against liver damage. However, more in vivo studies with female representation and a significant number of subjects are needed to confirm these results. Probiotics foods are related to improving health and obesity. An emergent tendency is developing probiotic foods (dairy or non-dairy based) with passion fruit or its by-products. Therefore, these new probiotic foods could be used in the transition from high sugar and fat foods to palatable-healthy foods in obese people to help them in their dietary pattern modifications. • In vivo studies, mainly in male rodents, have been used to test possible anti-obesity effects of Passiflora genus. • Passiflora supplementation prevents body fat accumulation and protects against liver damage. • Pectin and (poly)phenols compound would be responsible for Passiflora effects. • Passiflora as potential ingredient to obtain probiotic foods.

This article explores how diseases were contemplated and faced in Portuguese America in the early 1820s, shortly before the consolidation of the political rupture with Portugal that made Brazil an independent country. It analyzes who the individuals called to treat the diseases of the suffering population were, along with their knowledge and their therapies. To achieve this, we must begin by taking a step back in time, emphasizing the influences of the reforms of the Portuguese Empire on medical knowledge in the second half of the eighteenth century. The first section of the article is dedicated to exploring the complex and multifaceted healing practices in Portuguese America, resulting from the mixtures between traditional concepts about the body and the diseases that were part of the cultural references of the local population. The article then moves on to analyze some of the institutional and political conflicts involved in the consolidation of scientific medicine in Brazil, especially after the transfer of the Portuguese Court to Rio de Janeiro. Despite the political prestige of academic doctors, practitioners of the healing arts had broad support from the population, in addition to finding social mobility in the breaches of clientelistic relationships that marked the political culture of the period.

The present narrative review discusses the relevance and challenges of community participation in health for health system strengthening. Based on a definition of community participation in health as a dynamic process that gives people access and control over health resources through involvement and experience, the article summarizes information obtained from documents and debate at an international event (Seminario Internacional: Experiencias y Modelos de Participación en Salud en América Latina y el Caribe). In addition, the SciELO, PubMed and Google Scholar databases were searched using the terms "community participation", "community engagement", "social control" and "community health planning" to identify national or transnational review and opinion articles. Community participation in health is a current concept, acknowledged in the recommendations for health policies described in recent documents and publications. Around the world, the number of studies on the subject is growing; however, in the Americas, three countries (United States, Canada and Brazil) accounted for most of the scientific publications identified in the databases. The studies address timely questions and show consensus among investigators within each individual research group. However, the area lacks exchanges and comparative analyses that contrast different experiences transcending national borders and expanding knowledge on community participation in health. The creation of more spaces for the sharing of experiences and research is advised, as well as the establishment of professional and research networks in the field of community participation in health.

Simple Summary: Soybean meal is an effective protein source in aquafeeds and is characterized by high protein content, high digestibility, reasonable price, and stable supply. The quality of soybean meal varies with factors such as seed genotype, soil type, planting area, processing conditions, storage conditions, etc. Differences in soybean meal quality may lead to differences in the production performances of animals. For this reason, we investigated the nutrient composition, anti-nutritional factors and physicochemical properties of different soybean meals produced on the same production line with soybeans from different origins, and compared the effects of different soybean meals on the physiological characteristics of Nile tilapia (Oreochromis niloticus GIFT). This study identified key indicators that could distinguish the quality of soybean meals, and established a correlation model between quality indicators of soybean meal and the growth performance of Nile tilapia. These results are of great significance for evaluating the quality of soybean meals and promoting the efficient application of soybean meal in aquafeeds. Soybean meal (SBM) is the most important plant protein source in animal feed. This study investigated the characteristics of different SBMs, produced by soybeans from America and Brazil (SBM-A and SBM-B) in 2017–2021 under the same controlled conditions. The effects of different SBMs on the growth performance of Nile tilapia (Oreochromis niloticus, GIFT) and apparent digestibility coefficients (ADCs) of nutrients and energy were studied. The results showed that protein dispersibility index (PDI), urease activity (UA), glycinin and fiber were the four primary key indicators for distinguishing the characteristics of the tested SBMs. The meta-analysis results suggested that UA, glycinin, and fiber showed a negative effect on the survival rate (SR) and weight gain rate (WGR) of the Nile tilapia, whereas β-conglycinin, PDI, and nitrogen solubility index (NSI) had a positive effect on the SR and WGR of the fish. The ADCs of dry matter, the gross energy, phosphorus, crude protein, valine (Val), lysine (Lys), histidine (His), serine (Ser), and glutamate (Glu) of the Diet-A group (SBM-A inclusion) were significantly higher than those in the Diet-B group (SBM-B inclusion) (p < 0.05). However, no significant difference was found in ADCs of macro-nutrients between the two SBMs (p > 0.05). Overall, PDI, UA, glycinin, and fiber were the main indicators reflecting the characteristics of the tested SBMs, and UA, glycinin, β-conglycinin, and PDI had the greatest impact on the growth performance of Nile tilapia in this study. PDI was a more sensitive indicator than NSI for representing the protein quality of SBM. [ABSTRACT FROM AUTHOR]

Capsicum L. (tribe Capsiceae, Solanaceae) is an American genus distributed ranging from the southern United States of America to central Argentina and Brazil. The genus includes chili peppers, bell peppers, ajíes, habaneros, jalapeños, ulupicas and pimientos, well known for their economic importance around the globe. Within the Solanaceae, the genus can be recognised by its shrubby habit, actinomorphic flowers, distinctive truncate calyx with or without appendages, anthers opening by longitudinal slits, nectaries at the base of the ovary and the variously coloured and usually pungent fruits. The highest diversity of this genus is located along the northern and central Andes. Although Capsicum has been extensively studied and great advances have been made in the understanding of its taxonomy and the relationships amongst species, there is no monographic treatment of the genus as a whole. Based on morphological and molecular evidence studied from field and herbarium specimens, we present here a comprehensive taxonomic treatment for the genus, including updated information about morphology, anatomy, karyology, phylogeny and distribution. We recognise 43 species and five varieties, including C. mirum Barboza, sp. nov. from São Paulo State, Brazil and a new combination C. muticum (Sendtn.) Barboza, comb. nov.; five of these taxa are cultivated worldwide (C. annuum L. var. annuum, C. baccatum L. var. pendulum (Willd.) Eshbaugh, C. baccatum L. var. umbilicatum (Vell.) Hunz. & Barboza, C. chinense Jacq. and C. frutescens L.). Nomenclatural revision of the 265 names attributed to chili peppers resulted in 89 new lectotypifications and five new neotypifications. Identification keys and detailed descriptions, maps and illustrations for all taxa are provided. [ABSTRACT FROM AUTHOR]

Asthma affects a large number of people living in the Americas, a vast and diverse geographic region comprising 35 nations in the Caribbean and North, Central, and South America. The marked variability in the prevalence, morbidity, and mortality from asthma across and within nations in the Americas offers a unique opportunity to improve our understanding of the risk factors and management of asthma phenotypes and endotypes in children and adults. Moreover, a better assessment of the causes and treatment of asthma in less economically developed regions in the Americas would help diagnose and treat individuals migrating from those areas to Canada and the United States. In this focused review, we first assess the epidemiology of asthma, review known and potential risk factors, and examine commonalities and differences in asthma management across the Americas. We then discuss future directions in research and health policies to improve the prevention, diagnosis, and management of pediatric and adult asthma in the Americas, including standardized and periodic assessment of asthma burden across the region; large-scale longitudinal studies including omics and comprehensive environmental data on racially and ethnically diverse populations; and dissemination and implementation of guidelines for asthma management across the spectrum of disease severity. New initiatives should recognize differences in socioeconomic development and health care systems across the region while paying particular attention to novel or more impactful risk factors for asthma in the Americas, including indoor pollutants such as biomass fuel, tobacco use, infectious agents and the microbiome, and psychosocial stressor and chronic stress.

In the context of a taxonomic revision of the tribe Pleuroweisieae in South America, we studied a specimen of Hymenostylium that did not match any previously known species of this genus in America. Here we present our arguments for recognising this moss as a new species. The morphology of the potential new species was compared with that of the species of Hymenostylium presently recognised. A phylogenetic analysis based on the nuclear ITS and plastid rps4 regions was performed to investigate relationships between the new species and closely related taxa. Based on morphological and molecular data, we describe this new species from Brazil, Hymenostylium chapadense M.J.Cano & J.A.Jiménez. The species is strikingly distinguished by a stem with central strand and hyalodermis, oblong-ligulate to oblong-elliptical leaves that are when dry slightly crisped in the upper part and usually constricted just above the base and recurved on one side in the lower third, with uni- to bistratose margins, obtuse apex, costa wide and ending below the apex or percurrent with ventral and dorsal surface cells of the costa differentiated as an epidermis, and middle laminal cells usually with a simple, coarse, central papilla. Our molecular study placed H. chapadense as sister to H. hildebrandtii (Müll.Hal.) R.H.Zander. Possible confusion with the latter species and other closely related taxa is discussed. A key to the South American species of Hymenostylium is provided. [ABSTRACT FROM AUTHOR]

CLUSTER analysis (Statistics) , *MONSOONS , *HIERARCHICAL clustering (Cluster analysis) , *SEASONS , *TIME series analysis - Abstract
This work proposes an adaptation of the method developed in previous papers to determine the onset and demise of the rainy season (ONR and DER) dates in the areas of the South American monsoon system (SAMS) based on the pentad antisymmetric outgoing long‐wave radiation (AOLR). In those papers, the sign change of the mean AOLR in the central Amazon Basin (CAM) and western central Brazil (WCB) from positive to negative defined the ONR, from negative to positive, the DER dates. Since the monsoon convection presents a northwest–southeast oriented progression, the antisymmetric area to the WCB was selected subjectively. Thus, here we propose to use the Ward hierarchical clustering method to select areas in the SAMS and in the northern tropical America (NTA) for the regionalized AOLR calculation. The significant (at the 95% confidence level) negative correlations with the largest magnitude among the clusters in the SAMS and NTA and the outgoing long‐wave radiation (OLR) and precipitation annual cycles in each group define the pairs to calculate the AOLR. Then, the AOLR time series is calculated and subjected to a 5‐pentad running mean filter. This method keeps the climatological features of the convection annual cycle such that the closer (farther) the pair is to the equator the longer (shorter) the rainy season. The ONR and DER dates found with this new method are remarkably close to those found previously. Therefore, the new method proposed here highlights regional aspects of rainy season and can easily be automatized for its routine application at the operational climate monitoring centres, for instance at INPE. This is the most important advantage of the method and might be relevant to the SAMS rainy season monitoring. [ABSTRACT FROM AUTHOR]

This study presents a reflective analysis of the implementation of interprofessional education in undergraduate nursing courses, considering as an example the curricula of undergraduate nursing careers in Brazil. Despite investments to advance interprofessional education, its practice is not institutionalized in the curricula of undergraduate courses. These findings represent a limitation for the implementation of interprofessional education in nursing courses, and the case of Brazil allows to learn lessons for the education of nursing professionals in other countries of the Region of the Americas. Recommendations are provided for training, management and intersectoral articulation of health and education services, with emphasis on primary health care and the Sustainable Development Goals, aimed at educational institutions wishing to implement interprofessional education.

Objectives. To present the state-of-the-knowledge on the epidemiology of tungiasis in the Region of the Americas. Methods. A search of publications on the epidemiology of tungiasis in the Americas was performed in PubMed and LILACS databases from January 2007 to June 2021. In addition, a manual literature search on articles on the epidemiology of tungiasis was performed. Results. A total of 83 articles were analyzed which contained relevant information on tungiasis cases and their geographical distribution, prevalence and risk factors, life cycle, sites where transmission takes place, and zoonotic aspects. The on-host and off-host life cycles have been researched in detail. In certain contexts, the whole life cycle is completed indoors enabling transmission around the whole year. Cases were reported from 10 countries; 71% of them were from Brazil. In the general population, the prevalence varied between 1.0% and 82.6% according to the settings. Age-specific prevalence indicated that children and the elderly bear the highest disease burden. Risk factor studies indicate that tungiasis is associated with severe poverty. Conclusions. In the Americas, there are important gaps in information and knowledge of tungiasis. Understanding the burden, epidemiology, distribution, magnitude, related risk factors, and reservoirs, among others, is needed to develop and implement integrated control measures tailored to the context and patterns of transmission in the affected communities.

Objective: to analyze the factors that influence nurses' decisionmaking process in Ibero-American university hospitals. Method: a case study with a qualitative approach and of the multicenter type, carried out with 30 Ibero-American nurses. The data were collected through semi-structured interviews, analyzed by thematic categories and interpreted according to the theoretical framework of Creating Effective Organizations. Results: it was identified that the decision-making process permeates the development of nurses' own competencies, suffering influences from health management training and previous individual experiences. The following categories emerged: Technical-scientific preparation in decision-making; Hierarchization of the decision-making process; and Autonomous professional practice. Conclusion: the absence/presence of a rigid hierarchy, as well as technical-scientific preparation and autonomy, are factors that limit or expand the range of possibilities in nurses' decision-making, with consequences in care management. Thus, discussions about this theme should be encouraged, in order to promote nurses' autonomy for decision-making and favor a reduction of bureaucracy in the processes that prevent/hinder advances in these services.

Hepatitis B virus genotype A (HBV‐A) is disseminated in different countries around the world. It presents a high genetic diversity and is classified into seven subgenotypes (A1–A7). HBV‐A1 and HBV‐A2 are the most frequent and spread in almost all American countries. This study aimed to evaluate the molecular epidemiology of these two subgenotypes, with a special focus on the temporal and geographic spreading in the Americas and Brazil. Bayesian coalescent analyses with HBV‐A1 and HBV‐A2 whole‐genome sequences were performed to study viral phylodynamic and phylogeography. HBV‐A1 evolutionary history demonstrated that it was initially disseminated from Africa to other continents probably after the 1400s and mainly in the 17th–18th centuries. The whole viral population grew between the 1700s–1900s and then reached a stationary phase. In Brazil, HBV‐A1 common ancestors dated back to the 1600s with successive introductions between the 17th–18th centuries. In contrast, HBV‐A2 spread from Europe to other continents after the 1800s, with an increase in the viral population over decades. It was introduced in the 20th century in America and between the 1950s–1970s in Brazil, presenting a high increase in the viral population from the 1970s to the 1980s. The circulation continents for HBV‐A1 are Africa and America, while for HBV‐A2 are Europe and America. HBV‐A is one of the predominant genotypes in America (including Brazil) because of the early introduction by human migration processes of the subgenotypes A1 and A2 between the 16th and 20th centuries and the continuous spreading inside the continent over time.

GENETIC variation , *OIL palm - Abstract
Acrocomia (Arecaceae) is a genus widely distributed in tropical and subtropical America that has been achieving economic interest due to the great potential of oil production of some of its species. In particular A. aculeata, due to its vocation to supply oil with the same productive capacity as the oil palm (Elaeis guineenses) even in areas with water deficit. Although eight species are recognized in the genus, the taxonomic classification based on morphology and geographic distribution is still controversial. Knowledge about the genetic diversity and population structure of the species is limited, which has limited the understanding of the genetic relationships and the orientation of management, conservation, and genetic improvement activities of species of the genus. In the present study, we analyzed the genomic diversity and population structure of Acrocomia genus, including 172 samples from seven species, with a focus on A. aculeata with 117 samples covering a wide geographical area of occurrence of the species, using Single Nucleotide Polymorphism (SNP) markers originated from Genotyping By Sequencing (GBS).The genetic structure of the Acrocomia species were partially congruent with the current taxonomic classification based on morphological characters, recovering the separation of the species A. aculeata, A. totai, A. crispa and A. intumescens as distinct taxonomic groups. However, the species A. media was attributed to the cluster of A. aculeata while A. hassleri and A. glauscescens were grouped together with A. totai. The species that showed the highest and lowest genetic diversity were A. totai and A. media, respectively. When analyzed separately, the species A. aculeata showed a strong genetic structure, forming two genetic groups, the first represented mainly by genotypes from Brazil and the second by accessions from Central and North American countries. Greater genetic diversity was found in Brazil when compared to the other countries. Our results on the genetic diversity of the genus are unprecedented, as is also establishes new insights on the genomic relationships between Acrocomia species. It is also the first study to provide a more global view of the genomic diversity of A. aculeata. We also highlight the applicability of genomic data as a reference for future studies on genetic diversity, taxonomy, evolution and phylogeny of the Acrocomia genus, as well as to support strategies for the conservation, exploration and breeding of Acrocomia species and in particular A. aculeata.

This review aims to analyze the book Guerras de papel: comunicação escrita, política e comércio na monarquia ultramarina portuguesa, written by Romulo Valle Salvino. Adapted from his PhD thesis, the book dedicates to investigate the failed attempts of the Portuguese monarchy to create a postal system in its American colonies between the XVII and XVIIIth centuries. Investigating political conflicts and judicial disputes between different social actors, Salvino connects many scales of analysis -- individual, corporative, institutional and structural -- that were intertwined through complex colonial relations between the Metropolis and its American domains. The transformation of a jurisdictional conception of power in a political economy, and the end of the legitimacy of a patrimonial logic in the administration of the State formed the conditions in which the Luso-American merchants seek to oppose, in the city Councils, the Correio-mor assistants in Portuguese America. This book is an important historiographical landmark in the context of renewal of studies on material forms of circulation of writings, especially considering the recent efforts of scholars towards the history of the Post in Brazil.

• Examines unique cases: wild burros in America; rewilded donkeys in Europe; street donkeys in Brazil. • Binary framings (e.g. wild/domestic) are inadequate for free-roaming donkeys. • Specifies the 'entangled autonomy' of F-R donkeys using a relational approach. • Builds on scholarship in wild animal geographies and feral political ecologies. • Research on F-R donkeys would benefit from natural and social science collaboration. For thousands of years, the donkey (Equus asinus) has played an essential role in human society, underpinning the earliest forms of civilisation, facilitating critical trade networks, contributing to agricultural development, construction and mining. However, with the rise of motorised transport and agricultural machinery, the donkey was gradually turned loose in many places, and left free to roam. The emergence of freeroaming donkey populations has brought novel challenges for conservationists, land managers and animal welfarists alike. As non-native species that live and breed independently in large numbers, free-roaming donkeys appear as an ambiguous indeterminate group of wild-domestic creatures that sit uneasily with rapidly changing landscapes, societies and economies. This paper explores the status of free-roaming donkeys and the ongoing tension between the wild and the domestic, including the binary thinking underpins it and produces donkeys as non-native or 'out of place'. Using a relational approach and paying attention to the various ways in which freeroaming donkeys are entangled and embedded within cultural historical landscapes, this paper suggests how donkeys might be re-examined in terms of their 'entangled autonomy', building on recent interventions in 'wild' animal geographies and 'feral' political ecologies. In doing so, it reframes the debate around the status of freeroaming donkeys and posits an argument for how they might be considered to 'belong' or have legitimacy within these landscapes, suggesting that more attention needs to be given to the spaces and places that donkeys create or contribute to, as well as those they disrupt and challenge.

Temperature may regulate seed dormancy and germination and determine the geographical distribution of species. The present study investigated the thermal limits for seed germination of Polygonum ferrugineum (Polygonaceae), an aquatic emergent herb distributed throughout tropical and subtropical America. Seed germination responses to light and temperature were evaluated both before (control) and after stratification at 10, 15 and 20°C for 7, 14 and 28 d. Germination of control seeds was ~50% at 10 and 15°C, and they did not germinate from 20 to 30°C. The best stratification treatment was 7 d at 10°C, where seed germination was >76% in the dark for all temperatures, except at 30°C, and < 60% in light conditions. A thermal time approach was applied to the seed germination results. Base temperature (Tb) was 6.3°C for non-dormant seeds and optimal temperature (To) was 20.6°C, ceiling temperature (Tc (<50)) was 32.8°C, and thermal time requirement for 50% germination was 44.4°Cd. We concluded that a fraction of P. ferrugineum seeds is dormant, has a narrow thermal niche to germinate (10 and 15°C) and that cold stratification (10°C) alleviated dormancy and amplified the thermal range permissive for germination of the species. Consequently, P. ferrugineum is expected to occur in colder environments, for example, at high altitudes. Higher temperatures decrease the probabilities of alleviate dormancy and the ability of their seeds to germinate. [ABSTRACT FROM AUTHOR]

Objectives. To present the state-of-the-knowledge on the epidemiology of tungiasis in the Region of the Americas. Methods. A search of publications on the epidemiology of tungiasis in the Americas was performed in PubMed and LILACS databases from January 2007 to June 2021. In addition, a manual literature search on articles on the epidemiology of tungiasis was performed. Results. A total of 83 articles were analyzed which contained relevant information on tungiasis cases and their geographical distribution, prevalence and risk factors, life cycle, sites where transmission takes place, and zoonotic aspects. The on-host and off-host life cycles have been researched in detail. In certain contexts, the whole life cycle is completed indoors enabling transmission around the whole year. Cases were reported from 10 countries; 71% of them were from Brazil. In the general population, the prevalence varied between 1.0% and 82.6% according to the settings. Age-specific prevalence indicated that children and the elderly bear the highest disease burden. Risk factor studies indicate that tungiasis is associated with severe poverty. Conclusions. In the Americas, there are important gaps in information and knowledge of tungiasis. Understanding the burden, epidemiology, distribution, magnitude, related risk factors, and reservoirs, among others, is needed to develop and implement integrated control measures tailored to the context and patterns of transmission in the affected communities.

This study presents a reflective analysis of the implementation of interprofessional education in undergraduate nursing courses, considering as an example the curricula of undergraduate nursing careers in Brazil. Despite investments to advance interprofessional education, its practice is not institutionalized in the curricula of undergraduate courses. These findings represent a limitation for the implementation of interprofessional education in nursing courses, and the case of Brazil allows to learn lessons for the education of nursing professionals in other countries of the Region of the Americas. Recommendations are provided for training, management and intersectoral articulation of health and education services, with emphasis on primary health care and the Sustainable Development Goals, aimed at educational institutions wishing to implement interprofessional education.

LATIN American studies , *POSTCOLONIALISM , *EUROCENTRISM , *NEGLIGENCE - Abstract
In Latin American studies, the concept of ‘Latin/Latinity’ had a great influence on postcolonial thought and discourse, and it provided various implications for the task of overcoming western-centrism. However, it has long been overlooked that the concept of ‘Latin’ has become a tool for mutual exclusion and otherization between Spanish-speaking America and Brazil within the region defined by this term. This study examines how the concept of ‘Latin’ was recognized and accepted after independence in two axes of Latin America, ‘Hipano’ America and ‘Luso’ America, that is to say, Spanish America and Brazil, and how that recognition and acceptance defined the other and self-image between the two regions. Furthermore, by analyzing how the two worlds overcame the long period of mutual ‘negligence’ and shared ‘latinity’ and a shift in perception, this study presents the need for integrated study of both regions, which remains a non-small blank space in the field of study.

Along with other countries in America, plague reached Brazil through the sea routes during the third pandemic. A brief ports phase was followed by an urban phase that took place in smaller inland cities and finally, it attained the rural area and established several foci where the ecological conditions were suitable for its continued existence. However, the geographic dispersion of plague in Brazil is still poorly studied. To better understand the disease dynamics, we accessed satellite-based data to trace the spatial occurrence and distribution of human plague cases in Pernambuco, Northeastern Brazil and using the municipality of Exu as study case area. Along with the satellite data, a historical survey using the Plague Control Program files was applied to characterize the spatial and temporal dispersion of cases in the period of 1945–1976. Kernel density estimation, spatial and temporal clusters with statistical significance and maximum entropy modeling were used for spatial data analysis, by means of the spatial analysis software packages. The use of geostatistical tools allowed evidencing the shift of the infection from the urban to the wild-sylvatic areas and the reemergence of cases after a period of quiescence, independent of the reintroduction from other plague areas.

SAND flies , *LUTZOMYIA , *ECOLOGY , *VISCERAL leishmaniasis , *FOREST litter - Abstract
Sand flies are the insects responsible for transmitting Leishmania parasites, the causative agents of leishmaniasis in humans. However, the effects of sand fly breeding sites on their biology and ecology remain poorly understood. Herein, we studied how larval nutrition associated with putative breeding sites of the sand fly Lutzomyia longipalpis affects their oviposition, development, microbiome, and susceptibility to Leishmania by rearing L. longipalpis on substrates collected from an endemic area for leishmaniasis in Brazil. The results showed that female L. longipalpis select the oviposition site based on its potential to promote larval maturation and while composting cashew leaf litter hindered the development, larvae reared on chicken feces developed rapidly. Typical gut microbial profiles were found in larvae reared upon cashew leaf litter. Adult females from larvae reared on substrate collected in chicken coops were infected with Leishmania infantum, indicating that they were highly susceptible to the parasite. In conclusion, the larval breeding sites can exert an important role in the epidemiology of leishmaniasis. Author summary: Sand flies are the insect vectors involved in the transmission of many pathogens, however, the transmission of parasites to humans leading to visceral leishmaniasis is currently the most critical threat caused by this insect. Despite the importance of the vector, many aspects of the biology of sand flies are poorly understood, especially their breeding sites. This study was designed to evaluate the oviposition, life span, microbiome, and parasite infections in the main species of sand fly responsible for visceral leishmaniasis in America. Insects were reared on substrates collected from different putative habitats of sand flies in an endemic area for the disease in Brazil. The results showed that female vectors selected an oviposition site depending on the potential offered to their offspring. Furthermore, the development of immature stages varied according to the type of substrate evaluated, with cashew leaves litter delaying larval development, while chicken shelter promoted larval development. The challenge of females emerging from chicken shelter substrate with the parasite indicates that insects reared in such an environment could successfully sustain the infection. These results suggest that the type of breeding site can affect insect biology as well as the epidemiology of the disease. [ABSTRACT FROM AUTHOR]

This article investigates the representation of violence in Brazilian literary journalism in contemporary times. The objects of study are the report-novels that were featured in their category at the Jabuti Prize, a decoration of Brazilian literature, considered one of the largest in America. The objective is to understand, in a contextualized way, how violence is represented through these narratives and observe how Brazilian literary journalism contributes to the debate and the promotion of social reflection on the subject. To this end, a mapping of the works is initially carried out, in order to verify predominant themes, types of violence and types of domination that appear in the narratives, in order to start an understanding about the relations of power and the way violence is represented in Brazilian literary journalism. After this phase of comprehension, the analysis of the work Meu casaco de general, by the author Luiz Eduardo Soares, one of the first prizes in the studied periodis developed. The novel-report portrays violence especially in the context of relations between traffickers and police in the Rio de Janeiro space, but directing to an understanding of the entire Brazilian context. The results indicate that the decorated novels-reports, in the analyzed period, present several faces of the violence, since they represent how the subjects are affected by the cruelty, besides promoting a sense of empathy with the victims. There is also a strong link between the violence and the power relations that permeate the country. The work studied reveals social problems such as vulnerability to power relations, lack of ethics and corruption, themes that lead the reader to understand and question the system to combat violence in Brazil.
