Resumo: ABSTRACT Objective To investigate the relation between oxidative stress markers, human papillomavirus infection and cervical cancer precursor lesions. Methods The study comprised women aged 14 to 60 years living in communities located by Amazon rivers in the state of Pará (Itaituba, Limoeiro do Ajuru and Bragança, 126, 68 and 43 women respectively). Papanicolau smears and polymerase chain reaction tests for human papillomavirus DNA detection were performed. Blood samples were collected to test malondialdehyde, total and oxidized glutathione levels. Results Malondialdehyde, total and oxidized glutathione concentrations did not differ significantly (p>0.05) between women with and without low-grade squamous intraepithelial lesions across communities. Malondialdehyde levels (8.02nmols/mL) were almost five times higher in human papillomavirus-positive compared to human papillomavirus-negative women (1.70nmols/mL) living in Itaituba (statistically significant difference; p<0.05). Malondialdehyde levels did not differ significantly (p>0.05) between human papillomavirus-positive and human papillomavirus-negative women living in remaining communities. Significant (p<0.05) differences in total glutathione levels between human papillomavirus-positive and human papillomavirus-negative women (8.20μg/mL and 1.47μg/mL, respectively) were limited to those living in Bragança. Conclusion Malondialdehyde and total glutathione levels were significantly associated with human papillomavirus infection. However, lack of similar associations with squamous lesions suggest oxidative stress alone does not explain correlations with cervical carcinogenesis. Other factors may therefore be involved.

RESUMO Objetivo Avaliar a relação de marcadores de estresse oxidativo com a infecção pelo papilomavírus humano e as lesões precursoras do câncer cervical. Métodos Foram incluídas mulheres ribeirinhas da Amazônia (a saber: 126 do município de Itaituba, 68 de Limoeiro do Ajuru e 43 de Bragança), todas do Estado do Pará, de 14 a 60 anos. Foram realizados testes Papanicolau e de reação em cadeia de polimerase para a detecção de DNA do papilomavírus humano. Coleta de amostras de sangue foi realizada para a avaliação do malondialdeído e a determinação da glutationa total e oxidada. Resultados As concentrações oxidativas do malondialdeído e os teores de glutationa total e oxidada não apresentaram diferença significativa (p>0,05) nas mulheres com e sem lesão intraepitelial escamosa de baixo grau, em todas as comunidades pesquisadas. Mulheres com papilomavírus humano em Itaituba apresentaram níveis de malondialdeído (8,02nmols/mL) quase cinco vezes maior quando relacionadas àquelas sem o HPV (1,70nmols/mL), com diferença estatística significativa (p<0,05). As outras comunidades não mostraram diferença estatística significativa entre as concentrações de malondialdeído nas mulheres com e sem papilomavírus humano (p>0,05). Os teores de glutationa total mostraram diferença significativa (p<0,05) somente em Bragança naquelas com (8,20µg/mL) e sem a infecção pelo papilomavírus humano (1,47µg/mL). Conclusão Houve associação significativa da resposta oxidativa do malondialdeído e da glutationa total com a infecção pelo papilomavírus humano, porém não houve diferença quando associada à lesão escamosa, sugerindo que o estresse oxidativo isoladamente não explica a relação com a carcinogênese do colo uterino, que deve ser influenciada ainda por outros fatores.

Título: Amebas de Vida Libre aisladas en aguas superficiales del municipio de Turbaco, Bolívar-Colombia / Free-living amoebae isolated from surface water in the municipality of Turbaco, Bolívar, Colombia
Fonte: Rev. cuba. med. trop;68(1):0-0, abr. 2016. ilus, tab.
Idioma: es.
Resumo: Introducción: las amebas de vida libre (AVL) han sido aisladas de hábitat incluyendo: agua, suelo y vegetación. Los cambios ecológicos y la incursión de estos hábitats, han hecho que puedan invadir un hospedero y vivir como parásitos dentro de él. Por esto, las especies de los géneros Acanthamoeba y Naegleria han sido asociadas con infecciones oportunistas. Objetivo: evaluar la presencia de las amebas de vida libre en fuentes de agua natural en el municipio de Turbaco, con el fin de que sean consideradas en la conducta diagnóstica y terapéutica por las entidades de salud pertinentes. Métodos: se realizó un estudio descriptivo, transversal en los arroyos Matute, Mameyal y Cucumán del municipio de Turbaco - Bolívar. La identificación se hizo mediante el estudio de los frescos de las fuentes de agua observando características morfológicas de las amebas. Resultados: de un total de 54 muestras se obtuvo una positividad del 55,5 por ciento para una o más AVL. Con mayor frecuencia Naegleria sp con un 44,4 por ciento y Acanthamoeba sp, en un 7,4 por ciento. Además, se encontraron otros microorganismos responsables de parasitosis intestinales como: Giardia intestinalis, Blastocystis hominis y Retortomonas intestinalis. Conclusión: los arroyos estudiados son hábitat de las AVL, demostrando que están presentes en el ambiente y que son frecuentes en zonas donde el ser humano suele practicar ciertas actividades, sin embargo, la proporción de Naegleria sp. permite alertar aún más a la población puesto que esta ameba puede afectar a todo tipo de individuo independiente de su estado inmunológico(AU)

Introduction: free-living amoebae (FLAs) have been isolated from habitats such as water, soil and vegetation. As a result of ecological changes and incursion into these habitats, free-living amoebae have invaded hosts and settled within them as parasites. This is the reason why the species of genera Acanthamoeba and Naegleria have been associated with opportunistic diseases. Objective: determine the presence of free-living amoebae in natural water sources from the municipality of Turbaco, so they are taken into account by the corresponding health institutions in the design of diagnostic and therapeutic actions. Methods: a descriptive cross-sectional study was conducted of streams Matute, Mameyal and Cucumán in the municipality of Turbaco, Bolívar. Identification was based on the study of fresh water from the sources selected and observation of the morphological characteristics of amoebae. Results: of the total 54 samples, 55.5 percent tested positive for one or more FLAs. The most common were Naegleria sp with 44.4 percent and Acanthamoeba sp with 7.4 percent. Microorganisms were also found which cause intestinal parasitic disease, such as Giardia intestinalis, Blastocystis hominis and Retortomonas intestinalis. Conclusion: the streams studied are habitats for FLAs, showing that the latter are present in the environment and are common in areas where human beings perform certain activities. However, the proportion of Naegleria sp. makes it necessary to emphatically alert the population, since this amoeba may affect all individuals, irrespective of their immune status(AU)

Título: Efecto del microhábitat sobre la abundancia y riqueza específica de los macroinvertebrados bentónicos en dos ríos tropicales de montaña, Guatemala / Effect of microhabitat on the abundance and specific richness of benthic macroinvertebrates in two tropical mountain streams, Guatemala
Fonte: Cienc. tecnol. salud;6(1):7-21, 2019. ilus.
Idioma: es.
Resumo: Los macroinvertebrados bentónicos cumplen funciones ecológicas importantes en los sistemas lóticos, como el traspaso de energía a través de las redes tróficas, la descomposición de la materia orgánica, el reciclaje de nutrientes y la mezcla de sedimentos. Uno de los principales factores que definen la composición del ensamble de macroinvertebrados es la disponibilidad de microhábitats. Debido a ello, se evaluó el efecto de ocho microhábitats (hojarasca, grava, piedras, roca, musgo, vegetación acuática, pozas y cataratas), así como de la velocidad y profundidad, sobre la abundancia y riqueza específica de los macroinvertebrados en los ríos La Labor y Tzununá en la cuenca del lago Atitlán en el altiplano de Guatemala. Se colectaron 19,529 organismos correspondientes a 91 taxa, 49 familias y 65 géneros. El microhábitat que presentó mayor abundancia fue hojarasca (7,723 organismos) y pozas presentó la menor (652 organismos). En cuanto a riqueza, piedras presentó la mayor riqueza (41 taxa) y musgo tuvo la menor (28 taxa). Se evidenció que el microhábitat tuvo un efecto significativo sobre la abundancia y la riqueza (p < .05), ésta última también se vio influenciada por la profundidad (p = .030). Se concluyó que el microhábitat es un factor importante, para determinar la composición de la comunidad de macroinvertebrados; ya que la presencia y dominancia de elementos de heterogeneidad en los ríos, contribuye a incrementar la diversidad del hábitat físico, así como las opciones de alimento y refugio, promoviendo la abundancia y riqueza de macroinvertebrados en los sistemas lóticos.

Benthic macroinvertebrates serve important ecological functions in lotic systems, such as the transfer of energy through trophic networks, decomposition of organic matter, nutrient recycling and sediment mixing. One of the main factors that define the composition of the macroinvertebrate assemblage is the availability of microhabitats. The survey evaluated the effect of eight microhabitats (leaf litter, gravel, stones or pebbles, rock, moss, aquatic vegetation, pools and waterfalls), as well as speed and depth, on the abundance and specific richness due to rarefaction of the macroinvertebrates in La Labor and Tzununá rivers, which are part of the Lake Atitlán basin in the Guatemalan highlands. In this area 19,529 organisms corresponding to 91 taxa, 49 families and 65 genera were collected. The highest abundance was in leaf litter microhabitat (7,723 organisms), while stones showed the highest richness (41 taxa). Pools had the lowest abundance (652 organisms) and moss had the lowest richness (28 taxa). The microhabitat has a significant effect on abundance and richness (p < .05), also depth has a significant effect on richness (p = .030). The microhabitat is an important factor, to determine the composition of the macroinvertebrate community, because the presence and dominance of elements of heterogeneity in the rivers contributes to increase the diversity of the physical habitat, which provides refuge and food that satisfy the requirements of organisms promoting the abundance and richness of macroinvertebrates in lotic systems.

Resumo: En la región centroamericana, Guatemala comparte junto a Costa Rica, el tercer lugar en lo concerniente a la disponibilidad o volumen de agua. La cuenca del río Atulapa de 42.72 km2 de longitud, localizado en la parte alta del río Lempa, constituye un recurso hídrico de interés trinacional para las repúblicas de El Salvador, Honduras y Guatemala. La cuenca forma parte de la reserva Biosfera Transfronteriza Trifinio Fraternidad; declarada como reserva de biosfera en junio del 2011, por la Organización de las Naciones Unidas para la Educación, la Ciencia y la Cultura. Debido a los efectos del cambio climático y utilización de la tierra en la cuenca, ha disminuido la capacidad de retención de agua del suelo, por lo que en el presente estudio se evaluó el balance hídrico del suelo con el modelo de Thornthwaite y Mather. Los métodos y técnicas aplicados permitieron generar y evaluar registros hidrometeorológicos con estaciones digitales instaladas; así como también, la utilización de estaciones locales. Posteriormente, se utilizó un Sistema de Información Geográfica para programar el modelo de balance hídrico en el suelo con Python, simulando la distribución espacial de la precipitación, evapotranspiración potencial y real, contenido de humedad en el suelo, almacenamiento y escorrentía superficial. La textura del suelo y su cobertura permitió determinar la capacidad de retención de humedad. El 85% del territorio de la cuenca posee texturas franco arcillo-arenosas de origen volcánico y cultivo de café. El caudal medio anual en el río Atulapa es 0.59 m3/seg, la precipitación potencial media es 1,916 mm/año, la evapotranspiración real media es 873.08 mm/año, el déficit de disponibilidad de agua del suelo es de 465 mm/año. La variabilidad biofísica de la cuenca del río Atulapa, determinó la dinámica del balance hídrico del suelo.

In the Central American region, Guatemala shares the third place with Costa Rica in water availability or volume. The Atulapa River basin of 42.72 km2 is located in the upper part of the Lempa River, of Trinational interest for Guatemala, El Salvador and Honduras, within "La Fraternidad" Biosphere Reserve, of the Trifinio Plan declared by Unesco in June 2011. The effects of climate change and land use in the basin diminish the water retention capacity in the soil, the study evaluated the soil wáter balance with the Thornthwaite and Mather model. The methods and techniques included generating hydro meteorological records with installed digital stations, as well as the use of local stations. Later, a Geographic Information System was used to program the Python water balance model simulating the spatial distribution of precipitation, potential and actual evapotranspiration, soil moisture content, storage and surface runoff. The texture of the soil and its coverage allowed determining the capacity of moisture retention, 85% of the territory has clay-sandy franco textures of volcanic origin with coffee plantations. The mean annual rainfall in the Atulapa River is 0.59 m3/sec, the mean potential rainfall is 1.916 mm/year, the average real evapotranspiration is 873.08 mm/year, and the water availability deficit in the soil is 465 mm/year. The biophysical variability of the Atulapa river basin determined the dynamics of the soil water balance.

Resumo: Los modelos hidrometeorológicos, facilitan el control, monitoreo y planificación del recurso agua en cuencas hidrográficas, representando variables meteorológicas de forma distribuida. El objetivo del estudio, es proponer modelos hidrometeorológicos bidimensionales para cuantificar de forma precisa, las variables básicas que determinan la dinámica del recurso hídrico en la cuenca del río Atulapa, Esquipulas, departamento de Chiquimula, Guatemala. Se generaron y recopilaron datos hidrometeorológicos, con estaciones digitales instaladas y estaciones locales. Para el desarrollo de los modelos se elaboró una correlación entre altitud de las estaciones meteorológicas, como variable explicativa y registros climáticos como variable de respuesta. El modelo de escorrentía es una correlación entre alturas limnimétricas en la estación hidrométrica, como variable explicativa y el caudal óptimo de los aforos como variable de respuesta. La precipitación media de la cuenca obtenida con los modelos generados, es de 1,884 mm/año y la temperatura media de 18.92°C. El cambio de temperatura entre la parte baja y alta disminuye a razón de 1°C por cada 175 m.snm. El caudal medio anual es a razón de 0.5 m3 /seg en la estación hidrométrica del Puente. Los modelos hidrometeorológico generados en la cuenca del río Atulapa representaron la variabilidad climática en forma bidimensional, permitiendo un control y monitoreo del recurso hídrico en la cuenca, para la planificación del uso sostenible. La orografía en la cuenca, definió la estrecha relación con las variables meteorológicas precipitación y temperatura obteniendo modelos de regresión lineal precisos.

The hydrometeorological models facilitate the control and monitoring of the water resource in watersheds, representing meteorological variables in a distributed way, for the planning of the water resource. The objective of the study is to propose two-dimensional hydrometeorological models to accurately quantify the basic variables that determine the dynamics of water resources in the Atulapa River basin, Esquipulas, department of Chiquimula, Guatemala. Hydrometeorological data were generated and collected, with installed digital stations and local stations. For the development of the models, a correlation was made between the altitude of the meteorological stations, as an explanatory variable and climatic records as a response variable. The runoff model is a correlation between limnimetric heights in the hydrometric station, as an explanatory variable and the optimum flow of the gauging as a response variable. The average precipitation of the basin obtained with the generated models is 1,884 mm/ year and the average temperature is 18.92°C. The temperature change between the low and high part decreases at a rate of 1°C for every 175 masl. The average annual flow is at a rate of 0.5 m3 /sec at the Puente hydrometric station. The hydrometeorological models generated in the Atulapa River basin represented the climatic variability in two-dimensional form, allowing a control and monitoring of the water resource in the basin, for the planning of the sustainable use. The orography in the basin, defined the close relationship with meteorological variables precipitation and temperature obtaining accurate linear regression models.

Resumo: Abstract INTRODUCTION: The development of the São Francisco River Integration Project [Projeto de Integração do Rio São Francisco (PISF)] in the State of Ceará, Brazil, has resulted in environmental and socioeconomic changes with potential risks to public health. We aimed to determine the presence of Schistosoma mansoni infections in schoolchildren (aged 7-14 years) and workers from the construction site in an area under the direct influence of the PISF in the municipality of Brejo Santo-CE, to aid in the prevention and control of schistosomiasis. METHODS: We conducted a cross-sectional study using two S. mansoni-detection methods: detection of S. mansoni eggs by the Kato-Katz parasitological method in stool samples (assessed in triplicate for each sample) and S. mansoni circulating cathodic antigen by the point-of-care immunochromatographic rapid test (POC-CCA) in urine. RESULTS In general, the positivity rates for S. mansoni detection were 1.9% (2/106) among schoolchildren and 2.9% (4/138) among workers. No child had evidence of S. mansoni eggs in their stools; 1.9% tested positive by the POC-CCA method. Among workers, two (1.4%) tested positive by the Kato-Katz test and three (2.2%) by the POC-CCA test. If the POC-CCA test results that were scored as traces were considered negative, then the positivity rates dropped to 0.9% and 0.7% for schoolchildren and workers, respectively. CONCLUSIONS: The active transmission of schistosomiasis in a region covered by the PISF was recognized, reinforcing the necessity to consolidate surveillance and control actions, as well as structural sanitation measures to reverse the social determinants of the disease.

Título: Injuries caused by freshwater stingrays in the Tapajós River Basin: a clinical and sociodemographic study
Fonte: Rev. Soc. Bras. Med. Trop;50(3):374-378, May-June 2017. tab, graf.
Idioma: en.
Resumo: Abstract INTRODUCTION Freshwater stingray envenomations are an important cause of morbidity in riverine populations living in various regions of Brazil. The sequelae include temporary or permanent disability. This study aimed to identify sociodemographic, clinical, and therapeutic aspects related to stingray injuries in such populations. METHODS This cross-sectional study was conducted in the Extractive Reserve of Tapajos-Arapiuns, located in the municipalities of Santarém and Aveiro (Pará State). A convenience sample comprising 300 local adults was used to obtain data by means of a questionnaire/ interview. RESULTS Overall, 19 (6.3%) participants reported having sustained a stingray injury in the 12 months prior to the study. All 19 were injured either while fishing (n=13 [68.4%]) or engaging in other riverine activities. Most injuries [n=14 (73.7%)] occurred from September through November, and most injured respondents [n=15 (78.9%)] reported seeing stingrays at beaches. Severe pain and the appearance of ulcers in the later stages of envenomation were described by 18 (94.7%) and 12 (63.2%) participants, respectively. CONCLUSIONS Freshwater stingray injuries, which should be considered occupational injuries, are common in the study area, especially in places like beaches or in the lakes that form during the dry season, when stingrays are routinely observed. A significant proportion of respondents was unaware of the correct first aid measures and had insufficient resources to treat the complications of these injuries in the locality where they reside. Interactive activities involving local residents - such as lectures and the distribution of simple pamphlets providing information about stingray injuries - are needed.

Resumo: Abstract INTRODUCTION: The Middle Paranapanema watershed is known for the transmission of schistosomiasis, and there have been autochthonous cases since 1952. This study aimed to describe this disease in space and time and evaluate its current importance as a public health problem. METHODS: Thematic maps showing the risk areas for transmission of schistosomiasis, using scan statistics, and flow maps were created in the period 1978-2016. Incidence was calculated, and the existence of spatial dependence between autochthonous and imported cases was evaluated using Ripley's K12-function. Species of snails were identified in high-risk clusters. RESULTS: A total of 1,511 autochthonous cases were reported in eight of the 25 municipalities in the study area, of which 92.8% occurred in Ourinhos. A total of 2,189 imported cases were reported (27% in Ourinhos and 20% in Assis), mainly originating in the states of Paraná and Minas Gerais. Clusters of autochthonous and imported cases with higher risk were identified in Ourinhos, Assis and Ipaussu. However, over the years, the cases began to occur in low density in Ourinhos and no longer in other municipalities in the region. The cluster detected in the period 2007-2016 in Ourinhos still has risk for the transmission of schistosomiasis. K12-function analysis indicated positive spatial dependence between autochthonous and imported cases. CONCLUSIONS: The study showed that, currently, schistosomiasis as a public health problem in Middle Paranapanema is restricted to Ourinhos. This fact may be related to the presence of Biomphalaria glabrata at a specific point and low coverage of basic sanitation.

Resumo: A água constitui-se um recurso natural essencial aos seres vivos presente em todos os processos bioquímicos e fisiológicos, o que torna seu acesso indispensável às populações em geral. Diante disso, o presente estudo avaliou as características físico-químicas e microbiológicas da água proveniente do rio Jaguaribe, no trecho urbano do município de Jaguaribe, Ceará, Brasil, visando diagnosticar sua atual situação, e dispor de informações que contribuam para o monitoramento e garantia da sustentabilidade do recurso. A pesquisa foi realizada em um trecho do rio Jaguaribe, que percorre a zona urbana do município de Jaguaribe durante o período seco (Dezembro/2017) e chuvoso (Março/2018), sendo, portanto, dois pontos de coleta, um deles a montante e outro a jusante da cidade, nos bairros conhecidos como "Curralinho" e "Cruzeiro", respectivamente. Foram analisados os parâmetros físico-químicos de pH, temperatura, Condutividade Elétrica (CE) e cloreto e as variáveis microbiológicos tais como: Coliformes Totais, Fecais e Escherichia coli, todas as coletas foram realizadas em triplicatas. As variáveis físico-químicas apresentaram-se mais elevadas no período seco, porém seus resultados mostraram-se dentro dos valores médios verificados em outros trabalhos, salvo os da condutividade. Em relação aos parâmetros microbiológicos, não houve diferenças entre o período seco e chuvoso. Porém, em ambos foram encontrados, nos dois pontos de coleta, valores acima das médias estabelecidas pelo CONAMA. Diante dos resultados, constatamos que a contaminação do trecho não pode ser atribuída unicamente à cidade de Jaguaribe, comprovando que esta já chega à cidade com altos níveis de contaminação, principalmente por microrganismos (AU)

Water is an essential natural resource for living beings, present in all the biochemical and physiological processes, which makes its access indispensable to the populations in general. Therefore, the present study evaluated the physico-chemical and microbiological characteristics of water from Jaguaribe River in the urban area of the city of Jaguaribe, Ceará, Brazil, in order to diagnose its current situation, and to have information that contribute to the monitoring and the guarantee of resource sustainability. the research was carried out on a stretch of the Jaguaribe River, which runs through the urban area of the municipality of Jaguaribe during the drought (December / 2017) and rainy season (March / 2018) constituting, therefore, two collection points, one of them upstream and another downstream of the city, in the neighborhoods of "Curralinho" and "Cruzeiro", respectively. The physicochemical parameters of pH, temperature, electrical conductivity (EC) and chloride and microbiological variables such as: Total Coliforms, Fecal and Escherichia coli were analyzed, all collections were done in triplicates. The physical-chemical variables were higher during the drought season, but their results were within the mean values verified in other studies, except those of the conductivity. Regarding the microbiological parameters, there were no differences between the drought and rainy season. However, in both points of collection, values above the averages established by CONAMA were found. In view the results, we verified that the contamination the stretch can not attributed only to the city of Jaguaribe, proving that it already arrives to the city with high levels of contamination, mainly by microorganisms (AU)
