The cultural significance of the flora used by the native Asheninka Sheremashe community in Ucayali, Peru was determined. To do this, a fieldwork of over 4 months was conducted, involving semi-structured interviews with 106 residents through non-probabilistic convenience sampling. The community utilizes 139 plant species in their daily lives, belonging to 120 genera and 52 families, with the most abundant being Fabaceae, Arecaceae, Malvaceae, Solanaceae, Poaceae, and Rutaceae. Furthermore, 25.9% of the species are of significant importance to theinhabitants according to the Cultural Index (CI), such as Manihot esculenta, Theobroma cacao, Bixa orellana, Musa paradisiaca, Ficus insipida, among others. It can be concluded that the flora plays a prominent role in the life of the community, with the categories reporting the highest number of species being: food (29.35%), medicine (28.36%), culture (9.95%), construction (9.45%), lumber (6.97%), commerce (3.48%), craftsmanship (2.49%), toxic (2.49%), and other uses (7.46%)

Currently, in developing countries, parasitic and bacterial diseases as amebiasis, giardiasis, trichonomiasis, leishmaniasis, trypanosomiasis, tuberculosis, and nocardiasis are a public health problem. The pharmacological treatment for these diseases is not completely effective and causes several side effects in patients. Therefore, the search for new compounds with biological activity is very important to develop new drugs safely and more efficiently. In this study, different organic extracts obtained from thirty-seven species of the Salvadoran flora were evaluated in several in vitro models to determine their potential activity against five protozoa (Entamoeba histolytica, Giardia lamblia, Trichomonas vaginalis, Leishmania mexicana, and Trypanosoma cruzi) and three bacteria (Acinetobacter baumanni, Mycobacterium tuberculosis, and Nocardia brasiliensis). The results showed the activity of eight extracts with IC50values of less than 100 µg/mL against L. mexicanaand five extracts with MICs values less than <50 µg/mL against M. tuberculosis. Besides, seven plant species showed MICs ≤3.125 µg/mL against N. brasiliensis. Additionally, secondary metabolites (flavonoids and monoterpene oxygenate) previously reported as active were fingerprint by UPLC-MS to establish a potential correlation with the biological activity showed.
Actualmente, en los países en vías de desarrollo, enfermedades parasitarias y bacterianas como la amebiasis, giardiasis, trichonomiasis, leishmaniasis, tripanosomiasis, tuberculosis y nocardiasis son un problema de salud pública. El tratamiento farmacológico de estas enfermedades no es del todo eficaz y provoca varios efectos secundarios en los pacientes. Por lo tanto, la búsqueda de nuevos compuestos con actividad biológica es muy importante para desarrollar nuevos fármacos, seguros y eficaces. En este estudio se evaluaron diferentes extractos orgánicos obtenidos de treinta y siete especies de la flora salvadoreña en varios modelos in vitro para determinar su actividad potencial contra cinco parásitos (Entamoeba histolytica, Giardia lamblia, Trichomonas vaginalis, Leishmania mexicana y Trypanosoma cruzi) y tres bacterias (Acinetobacter baumanni, Mycobacterium tuberculosis y Nocardia brasiliensis). Los resultados mostraron la actividad de ocho extractos con valores de CI50 menores a 100 µg/mL contra L. mexicana y cinco extractos con valores de CIMs <50 µg/mL contra M. tuberculosis. Además, siete especies de plantas presentaron CIM ≤3,125 µg/mL frente a N. brasilienses. Finalmente, los metabolitos secundarios (flavonoides y monoterpenos oxigenados) previamente reportados como activos fueron determinados por UPLC-MS para establecer una posible correlación con la actividad biológica mostrada.

Introduction: Bacterial vaginosis is characterized by the imbalance of the vaginal flora, with decrease in Lactobacillus and increase in other bacteria. Objective: To investigate the prevalence and factors associated with bacterial vaginosis. Methods: Systematic review based on the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, filed in the International Prospective Register of Systematic Reviews. The research was conducted in the PubMed and Scopus databases in September 2021. After reading the titles and abstracts of 84 articles and the full text of 20 articles, 10 of them were included in the review. The articles were considered eligible if they investigated the prevalence of bacterial vaginosis and used Amsel's diagnostic criteria or Gram-stained bacterioscopy in women of reproductive age without comorbidities. The studies were evaluated by two investigators to establish reliability. The risk of bias and the quality of the selected studies were evaluated using the Joanna Briggs Institute tool. Results: The mean prevalence of bacterial vaginosis in the included studies was 25.4% (95%CI 24.026.8). In three population-based studies, the mean prevalence was 18.1% (95%CI 16.020.5); and in seven clinic-based studies, it was 27.2% (95%CI 24.629.9). The factors associated with bacterial vaginosis were the use of sex accessories (OR 2.4; 95%CI 1.14.9), marital status "single" (OR 1.4; 95%CI 1.11.8), partner infidelity (OR 1.5; 95%CI 1.21.9), abnormal vaginal secretion (OR 1.5; 95%CI 1.22.0), and the presence of trichomoniasis (OR 4.1; 95%CI 1.511.5). Conclusion: The prevalence of bacterial vaginosis was high, and the associated factors are linked to sexual behavior.
Introdução: A vaginose bacteriana caracteriza-se pelo desequilíbrio da flora vaginal, com diminuição dos Lactobacillus e aumento de outras bactérias. Objetivo: Investigar a prevalência e os fatores associados à vaginose bacteriana. Métodos: Revisão sistemática baseada nas diretrizes do Preferred Reporting Items for Systematic Reviews and Meta-Analyses, protocolado no International Prospective Register of Systematic Reviews. A pesquisa foi realizada nas bases de dados da PubMed e da Scopus, em setembro de 2021. Após a leitura dos títulos e dos resumos de 84 artigos e do texto completo de 20 artigos, dez foram incluídos na revisão. Os trabalhos foram considerados elegíveis quando investigaram a prevalência de vaginose bacteriana e utilizaram os critérios diagnósticos de Amsel ou a bacterioscopia corada pelo Gram em mulheres em idade reprodutiva e sem comorbidades. Os estudos foram avaliados por duas pesquisadoras para estabelecer a confiabilidade. O risco de viés e a qualidade das pesquisas selecionadas foram avaliados pela ferramenta do Joanna Briggs Institute. Resultados: A prevalência média de vaginose bacteriana nos trabalhos incluídos foi de 25,4% (intervalo de confiança IC95% 24,026,8). Em três estudos de base populacional, a prevalência média foi de 18,1% (IC95% 16,020,5); e, em sete estudos de base clínica, a prevalência média foi de 27,2% (IC95% 24,629,9). Os fatores associados à vaginose bacteriana foram o uso de acessórios sexuais (odds ratio OR 2,4; IC95% 1,14,9), estado civil "solteira" (OR 1,4; IC95% 1,11,8), infidelidade do parceiro (OR 1,5; IC95% 1,21,9), secreção vaginal anormal (OR 1,5; IC95% 1,22,0) e presença de tricomoníase (OR 4,1; IC95% 1,511,5). Conclusão: A prevalência de vaginose bacteriana foi elevada e os fatores associados estão ligados ao comportamento sexual.

Este estudo propõe analisar as relações e os processos de subjetivação de mulheres quebradeiras de coco babaçu decorrentes das intervenções de políticas desenvolvimentistas em seus territórios de vida e reverberações no Movimento Interestadual de Quebradeiras de Coco Babaçu (MIQCB). Sob a perspectiva ético-estético-política da Cartografia, acompanhamos as narrativas das histórias de vida de 24 mulheres, suas atividades cotidianas e eventos do MIQCB, também analisamos os documentos das políticas. Entendemos que, ao passo que tais políticas de desenvolvimento rural contribuem para a melhoria das condições de vida, em termos materiais e simbólicos, elas também produzem ressonâncias relacionadas ao modo de subjetivação do tipo "empresário de si", que agenciam seus modos de viver, de produzir e de se relacionar consigo e com os outros na lógica capitalista neoliberal. A resistência às capturas neoliberais também estão presentes ao ampliarem as mobilizações coletivas do próprio movimento, articulando com outros na produção de um "comum".(AU)
This study proposes to analyze the relations and the processes of subjectivation of babassu coconut-breaker women arising from developmental policy interventions in their territories of life and reverberations in the Babassu Coconut-breaker Interstate Movement (MIQCB). From the ethical-aesthetic-political perspective of Cartography, we followed the narratives of the life stories of 24 women, their daily activities and promoted events by MIQCB, we also analyzed the policy documents. We understand that while these policies of rural development contribute to improve the living conditions, in material and symbolic terms, they also produce resonances related to the "self-entrepreneur" mode of subjectivation, which has been handling their ways of living, producing, and relating to themselves and others in the neoliberal capitalist logic. Resistance to neoliberal captures is also present as they expand the collective mobilizations of the movement itself, articulating with others, in the production of a "common."(AU)

IntroductionIntestinal tumor is one of the most common tumors that seriously threaten the health of residents all over the world. Studies suggest that the imbalance of intestinal flora is associated with tumorgenesis; meanwhile, long-term regular aerobic exercise can improve the occurrence and development of tumors. However, moderate aerobic exercise affecting the development of intestinal tumors and their related flora has not been explored. Thus, the purpose of our study is to explore the effects of aerobic exercise on intestinal tumor growth and flora changes in ApcMin/+ mice, and try to answer whether there is a correlation between them after exercise intervention.MethodsIn this study, 18 required ApcMin/+ mice were randomly divided into Model group (n = 6), Exercise group (n = 6), and Aspirin group (positive control, n = 6), while C57BL/6 J wild-type mice were used as the blank control group. Each group is given corresponding intervention. Weight monitoring, tumor counts, hematoxylineosin staining, TdT-mediated dUTP nick-end labeling (TUNEL) fluorescence assay, immunohistochemistry (IHC), fecal sampling and grouping, and bacterial 16S rDNA gene analysis were completed after 12 weeks intervention for each group of mice.ResultsAs a result, we were able to show significant improvements in mice body weight changing rates (Exercise group 8.6% higher than Model control group), tumor numbers (Exercise group 4.33 ± 0.94 vs. Model control group 7.33 ± 2.49.

The study performed a checklist of publications on species with available seed information and identified their issues and volumes. These publications occurred during the existence of the online versions of Revista Brasileira de Sementes (Brazilian Journal of Seeds) and the Journal of Seed Science. This data survey intends to represent a foundation for other studies and contribute to the knowledge of native plant species in Brazil. The search focused on the seeds of plants native to Brazil, indicating high negligence regarding the knowledge of Brazilian biodiversity because of the total number of articles published in 33 issues of Revista Brasileira de Sementes between 2002-2012 and the Journal of Seed Science, a substitute of the former journal, from 2012 to the first semester of 2020, with 28 issues published, but only 208 studies addressing seeds of plant species native to Brazil.

Se han documentado un sin número de incendios forestales y no forestales en todo el planeta, y también se han descrito las causas, y se habla mucho sobre los efectos colaterales que ocasionan al ambiente, a las especies nativas y al cambio climático, pero muy pocos se centran en propuestas claves de recuperación de las comunidades afectadas, es por ello que aquí se describen una serie de estrategias que se trabajaron con la comunidad desde la recuperación de semillas de agaves hasta una propuesta de comercialización de su producto, contando con estrategias amigables con el ambiente y como la misma naturaleza a un año del incendio se sobreponen algunas especies, esto servirá como base para otros grupos de investigación en potencializar a los ciudadanos a mejorar su entorno y dejar el miedo e incursionar en la comercialización de su mezcal artesanal.(AU)
A number of forest and non-forest fires have been documented across the planet, and the causes have also been described, and much is said about the side effects they cause to the environment, native species and climate change, but very few They focus on key proposals for recovery of the affected communities, which is why here a series of strategies that were worked with the community are described, from the recovery of agave seeds to a proposal for the commercialization of their product, counting on friendly strategies with the environment and as nature itself one year after the fire some species overlap, this will serve as the basis for other research groups to empower citizens to improve their environment and leave fear and venture into the commercialization of their artizanal mezcal.(AU)

Introdução: A cesárea é realizada em condições maternas e/ou fetais que impeçam o nascimento via vaginal. Devido ao risco de complicações infecciosas, o procedimento é precedido de antibioticoprofilaxia, o que pode provocar a seleção de cepas multirresistentes e alterar a flora nativa do indivíduo. O colostro é um fator determinante para a colonização do trato digestivo por ser fonte probiótica, além de apresentar papel importante na modulação do sistema imunológico e desenvolvimento do neonato. Objetivo: Este estudo visa avaliar possíveis interferências da antibioticoprofilaxia realizada previamente à cesárea na flora materna. Métodos: Selecionou-se 140 lactantes após aplicação dos critérios de exclusão, divididas em grupos estudo (realizaram parto cesáreo com antibioticoprofilaxia) e controle (realizaram parto vaginal sem antibioticoprofilaxia) para coleta das amostras colostro e esfregaço areolar com intuito de realizar a análise microbiológica das mesmas no Laboratório de Microbiologia da Faculdade de Medicina de Barbacena. Resultados: 94 lactantes pertencem ao grupo estudo e 46 ao controle. O microrganismo mais prevalente em todas as amostras foi a Candida sp. Ao se discriminar os grupos, a mesma também apresentou maior prevalência, seguida de Enterococcus sp. Em relação à detecção de Staphylococcus aureus pelo esfregaço mamilar, ele foi encontrado em 24 amostras do grupo controle e em 34 do grupo estudo. Na análise comparativa da prevalência de microrganismos entre os grupos, não se observou diferença estatisticamente relevante. Conclusão: A antibioticoprofilaxia peri-operatória mostrou-se segura em não alterar a composição da flora materna. Entretanto, mais estudos sobre o tema devem ser realizados.
Introduction: The C-section is performed under maternal and / or fetal conditions that prevent vaginal birth. Because of the infectious complications, the procedure is preceded by antibiotic prophylaxis, which can cause the selection of multidrug-resistant strains and shift the individual's native flora. Colostrum is a determining factor for colonization of the digestive tract being a probiotic source, along with playing an important role in the modulation of the immune system and development of the newborn. Objective: This study aims to assess possible interferences of antibiotic prophylaxis performed prior to cesarean section on maternal flora. Methods: 140 lactating women were selected after applying the exclusion criteria, divided into study groups (94 lactating women who underwent cesarean delivery with antibiotic prophylaxis) and control groups (46 lactating women who underwent vaginal delivery without antibiotic prophylaxis) for sample collection - colostrum and areolar swab - therefore perform the microbiological analysis at the Laboratório de Microbiologia da Faculdade de Medicina de Barbacena. Results: The most prevalent microorganism in all samples was Candida sp. Discriminating the groups, it also had the highest prevalence, followed by Enterococcus sp. Regarding the detection of Staphylococcus aureus by the areolar swab, it was found in 24 samples from the control group and 34 from the study group. In the comparative analysis of prevalence of microorganisms, between the groups, there was no statistically significant difference. Conclusion: Perioperative antibiotic prophylaxis proved to be safe not changing the composition of the maternal flora. However, further studies on the subject should be carried out.

La Antártida es el continente más frío, seco, alto y ventoso; aquí, los líquenes y musgos crecen donde es más cálido, húmedo, bajo y protegido. En general, la productividad vegetal depende estrechamente de la longitud del periodo en el cual el agua líquida está disponible, por ello los vegetales se ven confinados a lugares con microclima excepcionalmente favorable. Es está fuerte relación entre microclima y disponibilidad de agua líquida y productividad /crecimiento, lo que hace a este ecosistema potencialmente tan útil para la monitorización del cambio climático global, especialmente en lo que se refiere al incremento de temperatura. Incluso un pequeño aumento de temperatura puede suponer un marcado incremento en el área afectada por estos periodos cálidos produciendo alteraciones en las comunidades vegetales. Es cada vez más claro que existen dos Antártidas, la Península y el continente. Se diferencian en el factor que controla la distribución de la biodiversidad vegetal. En la Península Antártica la temperatura sería el factor determinante y en el continente lo sería la disponibilidad de agua líquida. También el stress por radiación parece limitado a la zona continental. Se han llevado a cabo diferentes intentos de usar líquenes como monitores de cambio climático en regiones polares. La prístina Antártida ofrece una oportunidad única de estudiar el efecto del cambio climático a lo largo de gradientes latitudinales que se extienden entre 62º y 87º S. Tanto la diversidad de especies liquénicas, como sus tasas de crecimiento muestran correlaciones significativas con la temperatura y la precipitación anual a través del continente así como con las oscilaciones climáticas de periodo corto sucedidas en la Península Antártica. Las interacciones competitivas parecen ser pequeñas, de modo que cada individuo se desarrolla en equilibrio con las condiciones ambientales y, como resultado, puede indicar las tendencias en la productividad para intervalos temporales discretos dentro de un escenario de cambio climático. "Es todo aquí tan imponente, tan gigantescas todas las formas que las palabras no alcanzan a describirlo acertadamente. Nosotros cuatro somos los primeros seres humanos a quienes les ha sido dado asombrarse ante estas maravillas de la naturaleza y se nos antoja, a veces, que habrá de pasar largo tiempo antes de que otros pongan el pie en estos remotos parajes" (Diario de Shackleton, 4 de Diciembre de 1908)"
Antarctica is the coldest, driest, highest and windiest continent; the lichens and mosses grow where it is more warm, wet, low and protected. Overall productivity is strongly influenced by the length of period when water is available and the plants become, therefore, increasingly confined to areas of exceptionally good microclimate. It is this strong link between microclimate, water availability and productivity/growth that makes the system so potentially useful for monitoring global climate change, especially temperature increase. Even a small increase in temperature will markedly alter the areas over which such warm periods occur and bring with it a marked community shift. It is becoming clear that there are two Antarcticas, the Peninsula and the main continent. These differ in the controls on biodiversity distribution, there is a probably water unlimited but temperature-determined biodiversity cline in the Peninsula compared to a, water controlled, temperature-independent, fragmented vegetation in the continent. The reverse diel pattern of activity with the presence of very high light stress also seems to be confined to the continent. Several attempts have been made to use lichens as monitors of climate change especially in alpine and polar regions. The pristine Antarctica offers a unique opportunity to study the effects of climate change along a latitudinal gradient that extends between 62º and 87º S. Both lichen species diversity and thallus growth rate seem to show significant correlations to mean annual temperature and precipitation for gradients across the continent as well as to short time climate oscillation in the Antarctic Peninsula. Competition interactions appear to be small so that individual thalli develop in balance with environmental conditions and, as a result, can indicate the trends in productivity for discrete time intervals over long periods of time in a climate warming scenario

Este trabajo quiere mostrar una faceta del papel desempeñado por el coleccionismo y las colecciones científicas en la formación de los naturalistas durante la Edad de Plata de la ciencia española. El objetivo es evidenciar que la Junta para Ampliación de Estudios, principal institución que impulsó ese proyecto, aspiraba a crear intelectuales con capacidad de participar en la gobernanza del país (una nueva cultura política). La JAE encarnó un proyecto científico racionalista que se oponía a las visiones más conservadoras, defensoras de una ciencia católica, en una lucha que no se restringía a la ciencia, sino que alcanzaba lo social, lo político y lo cultural. Para ello recurrimos a la biografía del botánico José Cuatrecasas partiendo del enfoque de una historia sociocultural de la ciencia y una historia de las ideas
This work aims to show a piece of the important role that collecting and scientific collections played in the training to become naturalist during the Silver Age of Spanish science (1900-1936). It attempts to show that the Junta para Ampliación de Estudios (JAE), the main institution that promoted such a modern scientific project, aspired to create an intellectual elite with the capacity to participate in the governance of the State (a new political culture). The JAE incarnated a rationalist scientific model that opposed the ultraconservative positions, which were defenders of a Catholic science. Both of them were involved in a struggle that was not only restricted to science, but it reached all social, political and cultural aspects of national living. This article takes the biography of the botanic José Cuatrecasas as starting point and its analysis will be processed from the sociocultural History of Science and the History of Ideas

Este trabajo, inscripto en la historia de las ciencias, recorre cómo, en el reconocimiento científico del bosque andino patagónico argentino, se introducen valoraciones que ubican al mismo como parte de la salud social, que redunda en la jerarquización asimétrica de la población. Se revisan los escritos de los primeros naturalistas que, desde fines del siglo XIX, observan el espacio, y se avanza tomando estudios hasta entrada la década del '30. El recorte temporal se extiende hasta el establecimiento de políticas de conservación, a partir de la creación del Parque Nacional Nahuel Huapi, en 1934. La mirada sobre la ciencia indaga en las tradiciones de estudio de los diferentes grupos de especialistas que escriben sobre el espacio, y el modo en que estas investigaciones dialogan con políticas concretas de apropiación e intervención, que no se circunscriben a las prácticas internas de la biología de estos años, sino que se encuentran atravesadas por las concepciones organicistas desde las cuales se diseña la salud social. A lo largo de estas páginas se caracterizan las tradiciones de investigación en biología y se encuentra que las políticas trasladan, desde la mirada sobre la salud, los principios de conservación y uso social del bosque
This paper, as part of history of science, researches how the scientific recognition of Andean Patagonian Forest introduces values that located the forest as part of social health, and that implied the asymmetric hierarchy of the population. It reviews the writings of the first naturalists who study the countryside since the end of the 19th Century, and It continues taking into account studies until the late 1930's. The temporal cut covers until the establishment of conservation policies, starting with the creation of the Nahuel Huapi National Park in 1934. The analytical perspective over the science inquires into the study traditions of the different groups of specialists who write about space, and the forms that these researches were in dialogue with appropriation and intervention policies, which are not confined into the internal practices of the biology of these years, but are crossed by the organicist conceptions from which social health is designed. Along these pages the biological research traditions are characterized and it evidences that policies transfer, from social health conceptions, the principles of conservation and social use of the forest

The objective of this study was to examine, through an integrative review of empirical articles, the scientific production on the relation between Environmental Psychology (behavior/cognition variables) and sustainability considering different resources. For that purpose, this analysis considered articles approaching a unique resource. Search was conducted in three journals with international relevance in the scientific production of Environmental Psychology: Environment and Behavior, Journal of Environmental Psychology and Psyecology. Following pre-established inclusion criteria, results included 24 articles published from 2012 and 2016. Years with higher number of publications were 2014 (n = 8) and 2015 (n = 8). The articles found refer mostly to studies conducted in Europe; only one article is a research from Brazil. Resources included transportation, products, water, energy, plastic bag, and natural grassland. Results indicate that there is a diversity of concepts mediating behaviors/cognitions and different resources, which reveals the relevance of these approaches to the promotion of sustainability. Research and intervention paths are suggested to sustainable relations between people and resources available in their surroundings.(AU)

Abstract For accurate determination of polleniferous taxa vis-a-vis floral fidelity of Apis mellifera L. in North 24 Pargana, West Bengal, we carried out pollen analyses of individual corbicular pollen loads collected from four apiaries during 2015-2016. Among the 2 434 analyzed loads, 72.97 % were unifloral type, 19.0 % bifloral and 8.10 % were multifloral in pollen composition. We identified 43 different types of palynomorphs belonged to 28 botanical families. Major polleniferous plant species include: Alangium salviifolium, Borassus flabellifer, Brassica nigra, Coriandrum sativum, Croton bonplandianum, Cyanotis axillaris, Luffa cylindrica, Neolamarckia cadamba, Phoenix sylvestris, Poa gangetica, Sesamum indicum and Trema orientalis. Among them, T. orientalis is newly reported from West Bengal especially during June to August (monsoon season). The plant family provided maximum number of loads was Arecaceae (20.91 %), followed by Brassicaceae (16.2 %), Poaceae (6.70 %), Pedaliaceae (6.38 %), Apiaceae (6.16 %) and Fabaceae (5.38 %). Month wise highest number of pollen diversity were obtained during March (13 pollen types) and a minimum of 6 types in November. The present investigation will help the beekeepers to maintain their hives in the region for sustainable apicultural practices.(AU)
Resumen Para una determinación precisa de taxa polinífero y fidelidad floral de Apis mellifera en Pargana Norte 24, Bengala Occidental, realizamos análisis de cargas individuales de polen corbicular, recolectados en cuatro apiarios durante 2015-2016. De las 2 434 cargas analizadas, 72.97 % fueron de tipo unifloral, 19.0 % bifloral y 8.10 % multifloral, en la composición del polen. Identificamos 43 tipos diferentes de palinomorfos pertenecientes a 28 familias botánicas. Las especies principales de plantas poliníferas incluyen: Alangium salviifolium, Borassus flabellifer, Brassica nigra, Coriandrum sativum, Croton bonplandianum, Cyanotis axillaris, Luffa cylindrica, Neolamarckia cadamba, Phoenix sylvestris, Poa gangetica, Sesamum indicum y Trema orientalis. Entre estas, T. orientalis ha sido reportada recientemente en Bengala Occidental, especialmente de junio a agosto (temporada de monsones). La familia de plantas que presentó máxima cantidad de cargas fue: Arecaceae (20.91 %), seguida por Brassicaceae (16.2 %), Poaceae (6.70 %), Pedaliaceae (6.38 %), Apiaceae (6.16 %) y Fabaceae (5.38 %). De acuerdo al mes, el número mayor de diversidad de polen se obtuvo durante marzo (13 tipos de polen) y un mínimo de seis tipos en noviembre. La presente investigación ayudará a los apicultores a mantener sus colmenas en la región para prácticas apícolas sostenibles.(AU)

Introduction: Vaginal discharge is a frequent gynecological complaint, and may represent a disease or not. A vaginal discharge is considered recurrent when it occurs four or more episodes per year. Among the aetiologies, physiological and infectious conditions are mentioned, being the infectious ones, particularly those caused by Candida spp. fungus, the most related to the symptom. Despite the diagnostic and therapeutic resources available, empirical clinical treatments and self-treatments are very frequent and related to ineffective therapeutic results, leading this population to question what the differences regarding women with no symptoms are. Objective: To identify sociodemographic, behavioral and microbiological differences between women with recurrent vaginal discharge and asymptomatic women. Methods: Cross-sectional study involving 126 women with recurrent discharge complaints (study group) and 155 (control group), totaling 281 evaluated women. The group included women in the menacme, sexually active, and those who fit in the criteria of recurrent vaginal discharge, without definite previous diagnosis, compared with asymptomatic women, who attended an annual routine examination. Pregnant, diabetic and immunosuppressed women were excluded. The study was based on the principle of the null hypothesis, when there are no differences between the two studied groups. Results: The average age was 29.95 years, predominantly single and without children. There was no significant difference in the analysis of relationship time with the current partner, numbers of partners throughout life, gender and contraceptive method. There was predominance of normal vaginal flora (type 1) in both groups, with average prevalence of 44.9%. The alkaline vaginal pH was predominant in the study group. Conclusion: The null hypothesis was confirmed. Biological, behavioral and sociodemographic differences in the studied populations were not identified. In women with recurrent discharge group, there were no infectious etiologic factors, suggesting that clinical diagnoses are not sufficient for the most efficient management of these situations, indicating laboratory evaluation for these cases in order to improve diagnostic accuracy
Introdução: O corrimento vaginal é queixa ginecológica frequente, podendo ou não representar doença. Conceitua-se como corrimento vaginal recorrente aquele que ocorre em quatro ou mais episódios ao ano. Entre as etiologias, citam-se condições fisiológicas e infecciosas, sendo as infecciosas, particularmente as causadas por fungo Candida spp., as mais relacionadas ao sintoma. Apesar dos recursos diagnósticos e terapêuticos disponíveis, tratamentos clínicos empíricos e autotratamentos são muito frequentes e associados a resultados terapêuticos pouco efetivos, levando essa população a questionamentos sobre quais diferenças elas teriam em relação a mulheres sem sintomas. Objetivo: Identificar diferenças sociodemográficas, comportamentais e microbiológicas entre mulheres com corrimento vaginal recorrente e mulheres assintomáticas. Métodos: Estudo transversal envolvendo 126 mulheres com queixa de corrimento recorrente (grupo de estudo) mais 155 controles, totalizando 281 mulheres avaliadas. Foram incluídas no grupo de estudo mulheres no menacme, sexualmente ativas e enquadradas nos critérios de corrimento vaginal recorrente, sem diagnóstico prévio definido, comparadas a mulheres assintomáticas, que compareciam a exame de rotina anual. Foram excluídas as gestantes, diabéticas e imunossuprimidas. Partiu-se de princípio da hipótese nula, em que não há diferenças entre os dois grupos estudados. Resultados: A média de idade foi de 29,95 anos, predominando solteiras e sem filhos. Não houve diferença significativa quando analisados: tempo de relacionamento com o atual parceiro, número de parceiros ao longo da vida, sexarca e método anticoncepcional. Houve predomínio da flora vaginal normal (tipo 1) em ambos os grupos, com prevalência média de 44,9%. O pH vaginal alcalino foi predominante no grupo de estudo. Conclusão: Confirmou-se a hipótese nula, não se identificando diferenças biológicas, comportamentais e sociodemográficas nas populações estudadas. Não se observaram, no grupo de mulheres com corrimento recorrente, fatores etiológicos infecciosos, sugerindo que diagnósticos clínicos não são suficientes para o manejo mais eficiente dessas situações, indicando-se avaliação laboratorial para esses casos com o objetivo de melhorar a acurácia diagnóstica.
