Effect of particulate matter (PM2.5 and PM10) on health indicators: climate change scenarios in a Brazilian metropolis.

Recife is recognized as the 16th most vulnerable city to climate change in the world. In addition, the city has levels of air pollutants above the new limits proposed by the World Health Organization (WHO) in 2021. In this sense, the present study had two main objectives: (1) To evaluate the health (and economic) benefits related to the reduction in mean annual concentrations of PM10 and PM2.5 considering the new limits recommended by the WHO: 15 µg/m3 (PM10) and 5 µg/m3 (PM2.5) and (2) To simulate the behavior of these pollutants in scenarios with increased temperature (2 and 4 °C) using machine learning. The averages of PM2.5 and PM10 were above the limits recommended by the WHO. The scenario simulating the reduction in these pollutants below the new WHO limits would avoid more than 130 deaths and 84 hospital admissions for respiratory or cardiovascular problems. This represents a gain of 15.2 months in life expectancy and a cost of almost 160 million dollars. Regarding the simulated temperature increase, the most conservative (+ 2 °C) and most drastic (+ 4 °C) scenarios predict an increase of approximately 6.5 and 15%, respectively, in the concentrations of PM2.5 and PM10, with a progressive increase in deaths attributed to air pollution. The study shows that the increase in temperature will have impacts on air particulate matter and health outcomes. Climate change mitigation and pollution control policies must be implemented for meeting new WHO air quality standards which may have health benefits.

Health impact assessment of air pollutants during the COVID-19 pandemic in a Brazilian metropolis.

Studies around the world have revealed reduced levels of atmospheric particulate matter in periods of greatest human mobility restriction to contain the spread of SARS-CoV-2 during the COVID-19 pandemic. The present study aimed to carry out a health impact assessment in Recife, Brazil, hypothesizing a scenario in which the levels of PM10 and PM2.5 remained, throughout the year, as in the most restrictive period of human mobility. Particular material data (PM10 and PM2.5) were measured during the pandemic and population and health (mortality, hospital admissions for heart and respiratory problems) data from 2018 were used. We observed a reduction in the concentration of PM2.5 in up to 43.7% and PM10 up to 29.5% during the period of social isolation in the city of Recife. The reduction in PM2.5 would avoid 106 annual deaths from non-external causes and 58 annual deaths from cardiovascular diseases. In this scenario, $ 294.88 million would be saved ($ 114.88 million from heart problems and $ 180 million from non-external causes). When considering hospitalizations avoided by the decrease in PM10, we observed 57 fewer hospitalizations for respiratory diseases, 42 for heart diseases and a reduction of 37 deaths due to non-external causes. The reduction in spending on respiratory and cardiovascular hospitalizations would exceed $ 330,000. Therefore, the reduction of particulate matter could prevent hospital admissions, deaths and consequently there would be a reduction in disease burden in developing countries where economic resources are scarce. In this sense, governments should seek to reduce levels of pollution in order to improve the life quality and health of the population.

An Ethnographic Perspective on Urban Planning in Brazil: Temporality, Diversity and Critical Urban Theory.

This article provides an ethnographic perspective on urban planning by presenting the creative practices of marginalized slum residents in Recife, Northeast Brazil, who are affected by planners' decisions. It argues that such a perspective contributes to current critical urban theory in three ways. First, while many studies of urban planning follow the temporality of the timeframe of a particular project ('project time'), this analysis emphasizes the timeframe of the lives of the affected residents ('people's time'). Second, it attends to diversity, taking account of the variety of affected residents and the diverse consequences of urban planning on their lives. Third, it shows how urban interventions - similar to marriage, divorce, the birth of children and the death of loved ones - are high-impact life events for the urban poor. Finally, the article assesses the engagement between ethnography and critical urban theory and argues in favour of 'grounding' the latter better in the analysis of actual practices and experiences.

Comparing clinical protocols for the treatment of human rabies: the Milwaukee protocol and the Brazilian protocol (Recife)

Abstract INTRODUCTION: Rabies is a major and seriously neglected public health problem worldwide. A treatment consisting of supportive therapy with the use of drugs that show antiviral activity is called the Milwaukee Protocol. In Brazil, this protocol was adapted to the national reality and called the Recife Protocol. In this study, we compared the Milwaukee Protocol with the Recife Protocol, assessing the differences and how these differences may change the course of clinical management. METHODS We searched electronic databases for the use of anti-rabies treatments. A total of 65 articles were published between 2004 and 2019. RESULTS: The protocols have similarities in care related to rabies patients and are important for the treatment of patients in intensive care units. Both protocols indicate deep sedation, antiviral use, constant concern with electrolyte balance, and vasoconstriction related to the condition. Many differences were observed in this study. For the Milwaukee Protocol, sedation should be gradually removed after the eighth day, and on the twelfth day, the patient should be without sedation. In the Recife Protocol, in order to avoid immunomodulation, it is recommended to remove sedation according to the titers of neutralizing antibodies to the rabies virus in the cerebral spinal fluid. CONCLUSIONS: In addition to the differences and similarities raised, our findings indicate that these protocols require a large center for rabies treatment, but the disease most often occurs in places where resources and hospital infrastructure are scarce.

Scuticociliatosis caused by Uronema sp. in ten different ornamental aquarium reef fish in Brazil / Scuticociliatose causado por Uronema sp. em dez diferentes peixes ornamentais de recife no Brasil

Abstract Scuticociliatosis, caused by an opportunistic ciliate protozoan, is responsible for significant economic losses in marine ornamental fish. This study reports the occurrence of Uronema spp., parasitizing ten species of marine reef fish at an ornamental fish wholesaler: Blue green damselfish (Chromis viridis), Vanderbilt's Chromis (Chromis vanderbilti), Pennant coralfish (Heniochus acuminatus), Threespot angelfish (Apolemichthys trimaculatus), Goldspotted angelfish (Apolemichthys xanthopunctatus), Sea goldie (Pseudanthias squamipinnis), Orchid dottyback (Pseudochromis fridmani), Threadfin butterflyfish (Chaetodon auriga), Vagabond butterflyfish (Chaetodon vagabundus), and Bluecheek butterflyfish (Chaetodon semilarvatus). Diseased fish showed disorders such as hemorrhages and ulcerative lesions on the body surface. Histopathological analysis of the muscle, liver, gut, kidney, spleen, gills, and stomach revealed hemorrhages and degeneration of muscle fiber, vacuolar degeneration of hepatocyte, inflammatory process and granuloma in the liver, atrophy of intestinal villi, inflammatory process and granuloma in the kidney, melanomacrophage centers, as well as inflammatory process in the spleen, epithelial cells hyperplasia and granuloma formation in the gills, and vacuolar degeneration and eosinophils in the stomach. Due to the severity of the disease, it is necessary to implement biosecurity measures with rapid and accurate diagnosis to minimize the risk of economic losses caused by Uronema spp.

Resumo Scuticociliatose, causada pelo protozoário ciliado oportunista, é responsável por significativas perdas econômicas em peixes marinhos ornamentais. O estudo relata a ocorrência de Uronema spp., parasitando dez espécies de peixes de recife em um distribuidor de peixes ornamentais: "Blue green damselfish" (Chromis viridis), "Vanderbilt's Chromis" (Chromis vanderbilti), "Pennant coralfish" (Heniochus acuminatus), "Threespot angelfish" (Apolemichthys trimaculatus), "Goldspotted angelfish" (Apolemichthys xanthopunctatus), "Sea goldie" (Pseudanthias squamipinnis), "Orchid dottyback" (Pseudochromis fridmani), "Threadfin butterflyfish" (Chaetodon auriga), "Vagabond butterflyfish" (Chaetodon vagabundus), e "Bluecheek butterflyfish" (Chaetodon semilarvatus). Peixes doentes apresentaram distúrbios como hemorragias e lesões ulcerativas na superfície do corpo. A análise histopatológica do músculo, fígado, intestino, rim, baço, brânquias e estômago revelou hemorragias e degeneração das fibras musculares, degeneração vacuolar de hepatócitos, processo inflamatório e granuloma no fígado, atrofia das vilosidades intestinais, processo inflamatório e granuloma no rim, centros de melanomacrófagos e processo inflamatório no baço, hiperplasia das células epiteliais, bem como formação de granuloma nas brânquias e degeneração vacuolar e eosinófilos no estômago. Devido à gravidade da doença, é necessário implementar medidas de biossegurança com diagnóstico rápido e preciso para minimizar o risco de perdas econômicas causadas por Uronema spp.

Shape analysis of shark jaws as a tool to identify species involved in incidents with humans.

Shark incidents in Recife, Pernambuco state (Brazil), are registered since 1992. The occurrence of those events is in a relatively small area of urban beaches of about 30 km long, making up one of the world's highest indices of shark incidents per unit of area, totaling 64 casualties, of these 24 were fatal. To mitigate shark incidents, the knowledge on shark species involved is crucial given that each species has specific usage of the habitat and dissimilar feeding strategy. Jaws of five species caught along the Pernambuco coast (Brazil), corresponded to 2 specimens of Carcharhinus acronotus, 4 specimens of C. leucas, 1 of C. limbatus, 4 of Galeocerdo curvier and 3 of Sphyrna lewini. Relative Warps Analysis was applied to enhance possible differences among jaw shapes of the studied species. The consensus configuration from the 14 images was obtained. The first two relative warps components explained 70.17% of the total observed variation. Four distinct groups were clearly observed. Three groups were formed by single species, corresponding to G. curvier, C. leucas and S. lewini, respectively, and one group formed by the combination of C. acronotus and C. limbatus. As expected, due to its peculiar skull shape, S. lewini jaws are very different from other analyzed species, thus all observed individuals of this group were found isolated from the others, considering the horizontal axis. Relative warps and curvature analyses show to be useful tools in the forensic study of shark incidents. In general, jaws shape significantly differed among species.

"Among dead and wounded": mapping, characterization and analysis of fires with victims in Recife's metropolitan zone / "Entre mortos e feridos": mapeamento, caracterização e análise dos incêndios com vítimas na região metropolitana do Recife / "Entre muertos y heridos": cartografía, caracterización y análisis de los incendios con víctimas en la zona metropolitana de Recife

This article presents the mapping and analysis of fires with dead and wounded people in the Metropolitan Region of Recife (MRR) served by the Firefighters Department from 2013 to 2016. There was an average rate of 1 death per million inhabitants, similar to countries such as Singapore and Vietnam. The weighted number of fires per wounded or dead person results in rates of 0.5 and 1.7 per 100 recorded fires, respectively. These numbers are concerning, especially when compared to rates from other regions in the world. The victims of fires in MRR were shown to generally not be a perceivable problem in terms of common sense, yet they are real and require accurate analysis and effective measures.

Este artigo apresenta o mapeamento e a análise de incêndios com mortes e feridos na Região Metropolitana do Recife ­ RMR, atendidos pelo Corpo de Bombeiros, no período de 2013 a 2016. Verificou-se uma taxa média de 1 morte por milhão de habitantes, semelhante a países como Singapura e Vietnam. Quando se pondera a quantidade de incêndios para que haja um ferido ou morto, as taxas se apresentam respectivamente em 0,5 e 1,7 por 100 incêndios registrados ­ sendo estes números preocupantes, principalmente quando comparados com taxas de outras regiões no mundo. Conclui-se que as vítimas de incêndios na Região (RMR) são um problema silente ao senso comum, mas real e que exige análise acurada e providências efetivas.

Cuando se examina la cantidad de incendios para que haya un herido o muerto, los promedios se presentan respectivamente de 0,5 y 1,7 por 100 incendios registrados, lo cual es preocupante, principalmente en comparación con los promedios de otras regiones del mundo. Se concluye que las víctimas de incendios en la ZMR son un problema silencioso y real, lo que exige un análisis cuidadoso y diligencias efectivas.

"Eu não esperava por isso. Foi um susto": conceber, gestar e parir em tempos de Zika à luz das mulheres de Recife, PE, Brasil / "Yo no lo esperaba. Fue un susto": concebir, gestar y parir en tiempos de Zika en la visión de las mujeres de Recife, estado de Pernambuco, Brasil / "I never expected this, it was a big shock": conception, pregnancy and birth in times of zika through the eyes of women in Recife, PE, Brazil

Este artigo discute concepções de concepção, gestação e parto logo após o "boom" da epidemia de Zika no Brasil, a partir das narrativas de mulheres mães de bebês com microcefalia. Os seus filhos foram concebidos e gestados em um contexto sui generis, bastante caótico e inseguro, por conta do desconhecimento da raiz da deficiência, nas ruas de Recife e em bairros de camadas populares. A maioria nasceu em hospitais públicos da capital pernambucana. Dessa forma, procurando compreender tais experiências da vida sexual e reprodutiva dessas mulheres, com elas estivemos em 2016 e, depois, em 2017, por meio da observação diária de seu cotidiano e relações sociais, mas, nesse caso, a partir da memória de suas gestações e partos. Trata-se de mais uma particularidade, da vida sexual e reprodutiva das mulheres brasileiras, a ser pensada, por isso aqui recuperamos suas ideais e suas práticas, cotejando-as a outras, um pouco mais amplas, sobre o assunto.(AU)

Este artículo discute nociones de concepción, gestación y parto inmediatamente después del "boom" de la epidemia de Zika en Brasil, a partir de las narrativas de mujeres madres de bebés con microcefalia. Sus hijos fueron concebidos y gestados en un contexto sui generis, bastante caótico e inseguro, debido al desconocimiento de la raíz de la discapacidad, en las calles de Recife y en barrios de capas populares. La mayoría nació en hospitales públicos de la capital del estado de Pernambuco. De esa forma, buscando comprender tales experiencias de la vida sexual y reproductiva de esas mujeres, estuvimos con ellas en 2016 y después en 2017, por medio de la observación diaria de su cotidiano y relaciones sociales, pero, en ese caso, a partir de la memoria de sus gestaciones y partos. Se trata de una particularidad más de la vida sexual y reproductiva de las mujeres brasileñas que debe ser pensada y por eso aquí recuperamos sus ideas y prácticas comparándolas con otras, un poco más amplias, sobre la cuestión.(AU)

This article discusses conceptions of conception, gestation and childbirth shortly after the boom of the Zika epidemic in Brazil, from the narratives of female mothers of babies with microcephaly. His children were conceived and gestated in a sui generis context, quite chaotic and insecure, due to the deconditioning of the deficit, the roads of Recife and the neighborhoods of popular litters. Most were born in public hospitals in the state capital of Pernambuco. This way, trying to comprehend these sexual and reproductive experiences of these women, with her we were in 2016 and then in 2017, in this case, from the memory of your gestations and births. Try to be more of the particularity of sexual and reproductive life of Brazilian women, to be thought, for this reason we recover their ideals and practices, comparing them to others, a little wider, on the subject.(AU)

Surto de esporotricose felina na região metropolitana do Recife / Outbreak of feline sporotrichosis in the metropolitan area of Recife

A esporotricose é uma micose subcutânea, causada por um fungo dimórfico do complexo Sporothrix schenckii que acomete várias espécies, especialmente a felina, causando comprometimento local, disseminado ou sistêmico. Objetivou-se relatar a ocorrência de um surto de esporotricose felina na Região Metropolitana do Recife. Foram coletados suabes de úlceras cutâneas de felinos atendidos no Hospital Veterinário da Universidade Federal Rural de Pernambuco e em Clínicas Veterinárias particulares. O diagnóstico foi realizado por meio de exame citológico e cultura fúngica. Dos 115 casos suspeitos, 59 casos foram confirmados, número nunca registrado anteriormente no estado de Pernambuco. Os casos de esporotricose felina registrados têm demonstrado aspectos clínicos e epidemiológicos semelhantes aos ocorridos em outras regiões do país, caracterizando-se como uma doença predominantemente de machos jovens em idade reprodutiva e semi-domiciliados, de difícil tratamento e de rápida disseminação.(AU)

Sporotrichosis is a subcutaneous mycosis caused by a dimorphic fungus from Sporothrix schenckii complex, which affects various species, especially feline, able to cause local, disseminated or systemic impairment. We aimed to report the occurrence of an outbreak of feline sporotrichosis in the Metropolitan Region of Recife. Swabs of skin ulcers in cats treated in the Veterinary Hospital of the Federal Rural University of Pernambuco and in particular veterinary establishments were collected. Diagnosis was made by cytological examination and fungal culture. From 115 suspicious cases, 59 cases were confirmed, unprecedented results in the state of Pernambuco. These registered cases of feline sporotrichosis have demonstrated clinical and epidemiological characteristics similar to those occurring in other regions of the country, characterized as a quick-spreading disease, of difficult treatment, which affects predominantly semi-domiciled young males in reproductive age.(AU)

Multi-layered water resources, management, and uses under the impacts of global changes in a southern coastal metropolis: When will it be already too late? Crossed analysis in Recife, NE Brazil.

Coastal water resources are a worldwide key socio-environmental issue considering the increasing concentration of population in these areas. Here, we propose an integrative transdisciplinary approach of water resource, water management and water access in Recife (NE Brazil). The present-day water situation is conceptualized as an imbricated multi-layered system: a multi-layered water resource, managed by a multi-layered governance system and used by a multi-layered social population. This allows identifying processes of quantitative, qualitative, and sanitary conflicts between governance and population strategies regarding water supply, as well as the institutional and individual denials of these conflicts. Based on this model, we anticipate future water-related problematic fates. Concerning the water resource system, the rapid groundwater level decrease due to unsustainable water predatory strategies, and the very low recharge rate have drastically modified the aquifer system functioning, inducing hydraulic connection between shallow groundwater (contaminated and locally salty) and deep ones (mostly fresh, with local inherited salinity), threatening the deep strategic water resource. Concerning the water governance system, the investments to increase the capacity storage of surface water, the water regulation agencies and the public/private partnership should shortly improve the water supply and wastewater issue. Nevertheless, the water situation will remain highly fragile due to the expected water demand increase, the precipitation decrease and the sea-level increase. Concerning the water access system, the population variably perceives these current and further effects and the possible mitigation policies, and develops alternative individual strategies. Authorities, policymakers and water managers will have to implement a well-balanced water governance, taking into account the specificities of the PPP, public and private groundwater users, and with a strong political willingness for a sustainable water management to ensure water supply for all the population. In other words, an anticipatory and integrated vision is necessary to reduce the discrepancies in this complex system.

Bioecology and movements of bull sharks, Carcharhinus leucas, caught in a long-term longline survey off northeastern Brazil

A robust understanding of habitat usage by coastal shark species, and how it overlaps with human presence in densely-populated regions is needed to inform the development of efficient conservation strategies for these important top predators. An intensive longline survey conducted in nearshore waters off northeastern Brazil from 2004 through 2014 caught a total of 18 bull sharks (Carcharhinus leucas) (male-female ratio = 0.63:1), which can be dangerous to humans. Although most sharks were sexually mature, there was no evidence that this region could be used as a parturition or nursery area. Prey items identified in the guts of the sharks comprised teleosts, mollusks and elasmobranchs. Additionally, one satellite-tagged bull shark covered a great distance (> 3,000 km) in 75 days at liberty, making most use of shallow waters (< 20 m depth) and presumably also entering an estuarine area. Although bull sharks are not an important fishery resource in this region, such a reduced abundance coupled with its affinity for coastal and inshore habitats highlights the potential vulnerability of C. leucas to deleterious anthropic interferences off northeastern Brazil.(AU)

Um melhor entendimento sobre a utilização de hábitat das espécies de tubarões costeiros, e como ela se sobrepõe à presença humana em regiões altamente populosas, se faz necessário a fim de subsidiar o desenvolvimento de eficientes medidas de conservação para esses importantes predadores de topo. Um estudo intensivo utilizando espinhel, conduzido em águas costeiras do nordeste do Brasil entre os anos de 2004 e 2014, capturou um total de 18 tubarões cabeça-chata (Carcharhinus leucas) (proporção macho-fêmea = 0,63:1), os quais podem ser perigosos para humanos. Apesar da maioria dos tubarões estarem sexualmente maduros, não houve evidências de que essa região esteja sendo utilizada como uma área de parto ou berçário. Entre os itens alimentares identificados foram encontrados teleósteos, moluscos e elasmobrânquios. Além disso, um tubarão cabeça-chata marcado com um transmissor satélite percorreu uma grande distância (> 3.000 km) em 75 dias em liberdade, fazendo o uso de águas superficiais (< 20 m profundidade) e presumivelmente entrando em uma área estuarina. Apesar de os tubarões cabeça-chata não corresponderem a um recurso pesqueiro importante nessa região, tal reduzida abundância juntamente com a sua afinidade por hábitats costeiros reforçam a potencial vulnerabilidade de C. leucas às interferências antrópicas deletérias ao longo da costa nordeste do Brasil.(AU)

Origins and processes of groundwater salinization in the urban coastal aquifers of Recife (Pernambuco, Brazil): A multi-isotope approach.

In the coastal multilayer aquifer system of a highly urbanized southern city (Recife, Brazil), where groundwaters are affected by salinization, a multi-isotope approach (Sr, B, O, H) was used to investigate the sources and processes of salinization. The high diversity of the geological bodies, built since the Atlantic opening during the Cretaceous, highly constrains the heterogeneity of the groundwater chemistry, e.g. Sr isotope ratios, and needs to be integrated to explain the salinization processes and groundwater pathways. A paleoseawater intrusion, most probably the 120 kyB.P. Pleistocene marine transgression, and cationic exchange are clearly evidenced in the most salinized parts of the Cabo and Beberibe aquifers. All (87)Sr/(86)Sr values are above the past and present-day seawater signatures, meaning that the Sr isotopic signature is altered due to additional Sr inputs from dilution with different freshwaters, and water-rock interactions. Only the Cabo aquifer presents a well-delimitated area of Na-HCO3 water typical of a freshening process. The two deep aquifers also display a broad range of B concentrations and B isotope ratios with values among the highest known to date (63-68.5‰). This suggests multiple sources and processes affecting B behavior, among which mixing with saline water, B sorption on clays and mixing with wastewater. The highly fractionated B isotopic values were explained by infiltration of relatively salty water with B interacting with clays, pointing out the major role played by (palaeo)-channels for the deep Beberibe aquifer recharge. Based on an increase of salinity at the end of the dry season, a present-day seawater intrusion is identified in the surficial Boa Viagem aquifer. Our conceptual model presents a comprehensive understanding of the major groundwater salinization pathways and processes, and should be of benefit for other southern Atlantic coastal aquifers to better address groundwater management issues.

Spatial scale of cyanobacterial blooms in Old Providence Island, Colombian Caribbean / Escala espacial de afloramientos de cianobacterias en la Isla de Old Providence, Caribe colombiano / Escala espacial de afloramentos de cianobacterias na ilha Oíd Providence, Caribe colombiano

Cyanobacterial blooms have increased in coastal waters worldwide, facilitated by excessive nutrient input and apparently global warming. They exert negative consequences in marine ecosystems, communities and habitats. Although reports of these events are frequent, their spatial extent and affected habitats are not completely recognized, hence restricting regional management actions. We examined the presence, spatial scale and cover of cyanobacterial blooms in different habitats of the reef systems off Old Providence Island, and identified the main bloom forming taxa. Cyanobacteria were registered in four different ecosystems, six geomorphological zones and nine habitats. Benthic cyanobacteria reached 18 to 72 % of the total cover in five habitats, particularly at the northwest, east and southeast portions of the island. These blooms consisted of complex consortia belonging to the genera Okeania, Lyngbya, Symploca, Phormidium, Oscillatoria or Spirulina. A bloom of planktonic cyanobacteria was dominated by Trichodesmium and developed on the fore reef of the island (NW), following heavy rains. These results suggest a potential new stressor for the island's reef complex. Future research should focus on the environmental factors that enable cyanobacterial blooms and their local impact on ecosystems and services.

Los afloramientos de cianobacterias han incrementado en las zonas costeras de todo el mundo, favorecidos por el exceso de nutrientes y el aparente calentamiento global. Éstos tienen consecuencias negativas sobre los ecosistemas, comunidades y hábitats marinos. Aunque los reportes de estos eventos son frecuentes, la extensión y los hábitats afectados aún no han sido completamente caracterizados, lo cual limita las acciones de manejo. En este estudio examinamos la presencia, escala espacial y cobertura de afloramientos de cianobacterias en diferentes hábitats del complejo arrecifal de la isla de Old Providence, e identificamos los principales taxa que generan afloramientos. Las cianobacterias fueron registradas en cuatro ecosistemas, seis zonas geomorfológicas y nueve hábitats. Las cianobacterias bentónicas cubrieron entre el 18 y el 72 % del sustrato en cinco hábitats, particularmente en el noroeste, este y parte sur de la isla. Tales afloramientos estuvieron conformados por consorcios complejos pertenecientes a los géneros Okeania, Lyngbya, Symploca, Phormidium, Oscillatoria o Spirulina. El afloramiento de cianobacterias planctónicas estuvo dominado por Trichodesmium y se desarrolló en la terraza prearrecifal (NO), tras un periodo de fuertes lluvias. Los resultados sugieren un nuevo estresor potencial para el complejo arrecifal de la isla. La investigación futura debería concentrarse en los factores ambientales que facilitan los afloramientos de cianobacterias y en el impacto local sobre los ecosistemas y sus servicios.

Os afloramentos de cianobactérias tém aumentado em aguas costeiras de todo o mundo, devido á entrada de nutrientes excessivos e também aparentemente ao aquecimento global. Estes afloramentos exercem efeitos negativos nos ecossistemas, comunidades e habitats marinhos. Embora os relatónos destes eventos sejam frequentes na literatura, a extensao e os hábitats atingidos nao sao completamente conhecidos, o que implica a restricao das acoes de gestao. Neste estudo analisamos a presenta, escala espacial e cobertura dos afloramentos de cianobactérias em diferentes habitats marinhos do complexo recifal da ilha Old Providence, e identificamos as principais taxas que geram afloramentos. As cianobactérias foram registradas em quatro ecossistemas, seis zonas geomorfológicas e nove hábitats. Durante os afloramentos bentónicos, as cianobactérias atingiram entre 18 a 72 % da cobertura total em cinco habitats, particularmente no noroeste, este e sudeste da ilha. Tais afloramentos sao consorcios complexos pertencentes aos géneros Okeania, Lyngbya, Symploca, Phormidium, Oscillatoria e Spirulina. O afloramiento de cianobactérias planctónicas foi dominado por Trichodesmium e se desenvolveu no terrado prearrecifal da porc.ao noroeste da ilha, depois de chuva intensa. Os resultados sugerem um novo "estressor" potencial para o complexo recifal da ilha. As investigacoes futuras devem se concentrar nos fatores ambientais que facilitam o afloramiento e no seu impacto local nos ecossistemas e servicos.

Checklist of tidepool fishes from Jericoacoara National Park, southwestern Atlantic, with additional ecological information / Inventário dos peixes de poças de mare do Parque Nacional de Jericoacoara, Atlântico sudoeste, com informações ecológicas adicionais

Ichthyofauna from 29 tidepools in Jericoacoara National Park (Ceará State, Brazil) was sampled. A total of 733 fishes, comprising 16 species belonging to 12 families, was collected. The three most abundant species were the frillfin goby Bathygobius soporator, the sergeant-majorAbudefduf saxatilis and the molly miller Scartella cristata. An invasive species from the Indo-Pacific, the Muzzled blenny Omobranchus punctatus, was also recorded. The known geographic distribution of the blenny Hypleurochilus fissicornis was extended approximately 2,500 km northward. These findings highlight the lack of knowledge of the rocky intertidal ecosystems along the Brazilian coast, an area that needs more sampling effort and ecological data.

Um total de 733 espécimes de peixes, pertencentes a 16 espécies (12 famílias), foi capturado em 29 poças de maré no Parque Nacional de Jericoacoara (Ceará, Brasil). As espécies mais numericamente abundantes foram o amboré Bathygobius soporator, o sargentinho Abudefduf saxatilis e o macaco-verdeScartella cristata. Uma espécie invasora originária do Indo-Pacífico, Omobranchus punctatus, foi registrada para a área. A ocorrência de Hypleurochilus fissicornis permitiu expandir sua distribuição geográfica em cerca de 2.500 km ao norte. Esses resultados demostram que diversos aspectos relacionados a ictiofauna do ecossistema entremarés em substrato consolidado ainda permanecem pouco estudados no Brasil, e portanto, mais levantamentos da biodiversidade e dados ecológicos são necessários.

Pai Manoel, o curandeiro africano, e a medicina no Pernambuco imperial / Pai Manoel, African healer, and medicine in Imperial Pernambuco

O artigo relata a história de Pai Manoel, curandeiro que afirmava conhecer o remédio para o cólera. Escravo do engenho Guararapes, em Recife, durante o surto epidêmico de 1856 protagonizou episódio que colocou em xeque a atuação dos médicos e a eficácia dos tratamentos utilizados. O momento de crise deixou aparentes as tensões entre os que estavam autorizados a tratar os enfermos utilizando métodos científicos e outros, que o faziam a partir de saberes tradicionais. São discutidos temas como a configuração do campo da medicina no Brasil e, sobretudo, em Pernambuco, e as estratégias criadas para obter exclusividade de atuação e combater as formas de cura concorrentes.

The article tells the story of Pai Manoel, a healer who claimed he had a remedy for cholera. A slave from the Guararapes sugarcane plantation in Recife, Pai Manoel was the center of an episode during the 1856 epidemic outbreak that called into question the work of physicians and the efficacy of the treatments they used. This moment of crisis revealed underlying tensions between those who were authorized to treat the infirm, applying scientific methods, and others, who used traditional knowledge in their treatment. The article discusses such topics as the shaping of the field of medicine in Brazil and, especially, in Pernambuco, and the strategies devised to guarantee the exclusive right to practice medicine and to combat competing forms of healing.

Perfil de mortalidade do idoso: análise da evolução temporal em uma capital do Nordeste brasileiro de 1996 a 2007 / The elderly mortality profile: analysis of the temporal evolution in a capital of the Brazilian northeast from 1996 to 2007

OBJETIVO: Este trabalho objetivou analisar a evolução temporal da mortalidade de idosos no município de Recife no período de 1996 a 2007. MÉTODOS: Realizou-se estudo de evolução temporal, com o universo de óbitos da população idosa (>60 anos). Os coeficientes de mortalidade foram calculados, padronizados por idade e sexo, pelo método direto para subgrupos etários, sexo, estado civil, causa básica de óbito, local de ocorrência e assistência médica na base de mil habitantes. Foram realizadas análises descritivas e análise de regressão linear. RESULTADOS: A mortalidade em idosos no Recife apresenta tendência de declínio na série analisada, com maiores coeficientes entre os idosos longevos (>80 anos). Os idosos homens apresentam maior mortalidade em relação às idosas, com tendência de diminuição dos coeficientes. Quanto ao estado civil, houve aumento da mortalidade entre idosos solteiros e separados judicialmente. A maioria dos óbitos ocorreu em hospitais e com assistência médica no momento do óbito. Foi observada tendência de decréscimo da mortalidade por doenças do aparelho circulatório, doenças infecciosas e parasitárias, doenças do aparelho digestivo e sinais e sintomas mal definidos e aumento da mortalidade por doenças do aparelho geniturinário. A evolução da mortalidade por neoplasias, doenças endócrinas, nutricionais e metabólicas, doenças do aparelho respiratório e causas externas não sofreu variações. CONCLUSÕES: A mortalidade do idoso recifense apresentou padrão semelhante à realidade nacional, destacando-se a tendência de redução dos coeficientes de mortalidade.

OBJECTIVE: This paper focused on analyzing the temporal evolution of elderly mortality in Recife from 1996 to 2007. METHODS: A study of the temporal evolution was made, considering the universe of obits of the elderly population (>60 years old). Mortality coefficients were calculated, standardized by age and gender, through the direct method for sub-groups of age, gender, marital status, basic cause of death, place of death and medical assistance. Descriptive analysis and linear regression analysis were performed. RESULTS: Elderly mortality in Recife shows a tendency to decline in the series analyzed, with higher coefficients in the long-lived elderly (>80 anos). The male elderly show higher death rates compared to the female, with a tendency to decline the coefficients. In relation to the marital status, there has been an increase on the death rate concerning the single and legally divorced elderly. Most of the obits have occurred in hospitals and with medical assistance at death. A tendency to decrease the death rate through diseases in the circulatory system, infectious and paralyzing diseases, diseases in the digestive system, and not well-defined signs and symptoms has been observed, as well as an increase in death rate through diseases in the genito-urinary system. CONCLUSIONS: Elderly mortality in Recife has shown a similar standard to the national reality, with an outstanding tendency to decrease the death coefficients.

Perfil dos idosos em situação de violência atendidos em serviço de emergência em Recife-PE / Profile of elderly in violence situation assisted at an emergency service in Recife-PE

OBJETIVO: Determinar o perfil da violência sofrida pelo idoso atendido em serviço de emergência do Hospital da Restauração (HR), em Recife-PE. METODOLOGIA: Estudo epidemiológico, descritivo, quantitativo de corte transversal. Foram analisados todos os prontuários médicos referentes aos atendimentos em cirurgia geral, ortopedia e clínica médica realizados na emergência de adultos do HR entre 1º de janeiro e 31 de dezembro de 2007, disponibilizados pelo Serviço de Arquivo Médico, totalizando 72.232 prontuários. RESULTADOS: Do total de prontuários analisados, foram registrados 79 casos de violência contra o idoso. Destes, 63,3% do sexo masculino. A faixa etária predominante foi compreendida entre 60-70 anos (72,2%). Em 81,1% dos prontuários, não houve registro sobre vínculo empregatício ou situação previdenciária do agredido. Em relação ao local de residência da vítima, a maioria (46,8%) residia em Recife-PE. Quanto ao levantamento de dados sobre o agressor, quando este foi citado (3,7%), todos pertenciam ao sexo masculino, sendo notificada a relação com a vítima em um único caso (filho). O tipo de violência mais frequente foi a física (97,5%). Quanto à natureza da lesão, a mais comum foi a contusão (27,8%). Os sítios de lesão mais acometidos foram a face (35,4%), crânio (31,6%) e extremidades (22,8%). Em relação ao instrumento, os contundentes foram os mais utilizados (29,1%), seguido dos perfuro-cortantes (19%). O mês de janeiro prevaleceu com o maior número de atendimentos (21,6%) e os casos de violência ocorreram principalmente na sexta-feira (16,1%), quarta-feira (17,7%), sábado (17,7%) e domingo (17,7%). CONCLUSÃO: O idoso vítima de violência foi principalmente homem, com faixa etária de 60-70 anos. O tipo de violência mais frequente foi a física, especialmente contusão em face ou crânio, ocorrendo mais no fim de semana.

OBJECTIVE: To determine the profile of violence suffered by elderly assisted at the emergency department. METHODOLOGY: Epidemiological, descriptive, quantitative cross-sectional study. Were analyzed all medical records of care provided in General Surgery, Orthopedics and Internal Medicine in adult emergency between January 1st and December 31, 2007, provided by the Service Medical Records, totaling 72,232 records. RESULTS: There were 79 cases of violence against elderly, of which 63.3% were male. The predominant age group was between 60-70 years old (72.2%). In 81.1% of the medical charts there was no records of employment. Regarding residence of the victim, the majority (46.8%) lived in Recife city, Pernambuco state, Brazil. About data of the offender, when it was quoted (3.7%), all of them were males, reported being the relationship with the victim in a unique case (child). The most frequently found violence was physical (97.5%). The most common injury was contusion (27.8%). The sites of injury most affected were face (35.4%), head (31.6%) and extremities (22.8%). In relation to the instruments, blunt was used in 29.1%, followed by piercing-cutting (19%). January had the highest number of attendances (21.6%). Violence occurred mainly on Fridays (16.1%), Saturdays (17.7%) and Sundays (17.7%). CONCLUSION: The elderly victim of violence is primarily male, ranging 60-70 years of age. The most frequent type of violence is physical, especially in face or skull injury, occurring over the weekend.

Spatial distribution of epibenthic molluscs on a sandstone reef in the Northeast of Brazil / Distribuição espacial de moluscos epibentônicos em um recife arenítico no Nordeste do Brasil

The present study investigated the distribution and abundance of epibenthic molluscs and their feeding habits associated to substrate features (coverage and rugosity) in a sandstone reef system in the Northeast of Brazil. Rugosity, low coral cover and high coverage of zoanthids and fleshy alga were the variables that influenced a low richness and high abundance of a few molluscan species in the reef habitat. The most abundant species were generalist carnivores, probably associated to a lesser offer and variability of resources in this type of reef system, when compared to the coral reefs. The results found in this study could reflect a normal characteristic of the molluscan community distribution in sandstone reefs, with low coral cover, or could indicate a degradation state of this habitat if it is compared to coral reefs, once that the significantly high coverage of fleshy alga has been recognized as a negative indicator of reef ecosystems health.

O presente estudo investigou a distribuição, a abundância e os hábitos alimentares de moluscos epibentônicos associados à cobertura e à rugosidade do substrato, em um sistema recifal arenítico no Nordeste do Brasil. A rugosidade, a baixa cobertura de corais e a alta cobertura de zoantídeos e algas frondosas foram as variáveis que influenciaram na baixa riqueza e na alta abundância de poucas espécies de moluscos no habitat recifal. As espécies mais abundantes foram classificadas em carnívoras generalistas, provavelmente associadas à baixa oferta e variabilidade de recursos nesse tipo de sistema recifal, quando comparado a recifes coralíneos. Os resultados encontrados neste estudo podem estar refletindo características normais para a distribuição dos moluscos em recifes areníticos, com baixa cobertura de coral, ou podem estar indicando um estado de degradação desse habitat, quando comparado aos recifes de corais, uma vez que a cobertura significativa de algas frondosas vem sendo reconhecida como um indicador negativo quanto à saúde dos ecossistemas recifais.

O traço francês na arquitetura do Recife: o Hospital Pedro II / French lines in Recife architecture: Pedro II Hospital

Em 1861 foi inaugurado em Recife o Hospital Pedro II que, durante várias décadas, serviu como instituição de referência no estado de Pernambuco e no Nordeste. O prédio foi construído segundo o modelo francês, desenvolvido pelo médico Jacques-René Tenon: o estilo pavilhonar, que prevaleceu em Pernambuco e no Brasil por muitos anos. Em 1982, o nosocômio quase foi abandonado e, em seguida, graças à negociação entre o Instituto de Medicina Integral Prof. Fernando Figueira e a Arquidiocese de Olinda e Recife , foi restaurado e inaugurado, oferecendo diversos serviços para a sociedade.

Pedro II Hospital was inaugurated in Recife in 1861 and for several decades was the leading center of its kind in the state of Pernambuco and in Northeast Brazil. Its construction followed French design, as developed by physician Jacques-René Tenon, that is, the so-called pavilion style that was the norm in Pernambuco and in Brazil for many years. After being nearly abandoned in 1982, the hospital was reformed shortly thereafter and reopened its doors to offer a variety of services, thanks to negotiations between the Instituto de Medicina Integral Professor Fernando Figueira and the Archdiocese of Olinda and Recife.

Mycale alagoana sp.nov. and two new formal records of Porifera (Demospongiae, Poecilosclerida) from the shallow-water reefs of Alagoas (Brazil) / Mycale alagoana sp.nov. e dois novos registros formais de Porifera (Demospongiae, Poecilosclerida) dos recifes rasos de Alagoas, Brasil

The Porifera occurring at Alagoas State reefs (north-eastern Brazil) are still little-known, with few species listed and even fewer formally described. From a total of 48 species recorded from the state, only eight belong to the Poecilosclerida, including those (re)described in this study. Here we describe a new species, Mycale (Mycale) alagoana sp.nov., and redescribe two species: Lissodendoryx (Lissodendoryx) isodictyalis (Carter, 1882) and Mycale (Naviculina) diversisigmata Van Soest, 1984, both first formal redescriptions from the Southwestern Atlantic. Additionally, Mycale (Aegogropila) escarlatei Hajdu et al., 1995 is here reported from Alagoas for the first time, in discussing the difficulties inherent to recognition in the field of small crustose Mycalids with neatly reticulated surfaces.

Os poríferos dos recifes do Estado de Alagoas (nordeste do Brasil) são ainda pouco conhecidos, com poucas espécies formalmente descritas. Dentre as 48 espécies de Demospongiae registradas para o estado, apenas oito pertencem à Ordem Poecilosclerida, incluindo o material (re)descrito aqui. No presente estudo se descreve uma espécie nova Mycale (Mycale) alagoana sp.nov., e duas espécies são redescritas: Lissodendoryx (Lissodendoryx) isodictyalis (Carter, 1882) e Mycale (Naviculina) diversisigmata Van Soest, 1984, ambas, primeiras redescrições formais para para o Sudoeste do Atlântico. Adicionalmente, Mycale (Aegogropila) escarlatei Hajdu et al., 1995 é registrada aqui para Alagoas pela primeira vez, na discussão das dificuldades inerentes ao reconhecimento em campo de pequenos Mycalídeos incrustantes com superfícies claramente reticuladas.
