Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Constipation prevalence and associated factors in adults living in Londrina, Paraná, Brazil.

A partir do desenvolvimento dos Critérios de Roma, muitos estudos têm sido realizados para o conhecimento da epidemiologia da constipação intestinal (CI). Porém, a maioria é realizada em grupos populacionais específicos e poucos são aqueles de base populacional. Os objetivos do presente estudo foram estimar a prevalência de CI em adultos da população geral na área urbana de Londrina, Paraná, e identificar os fatores demográficos e clínicos associados à ocorrência de CI nessa população. Trata-se de uma análise secundária, desenvolvida a partir de um estudo epidemiológico de base populacional, descritivo, exploratório e com coleta transversal dos dados, sobre o hábito intestinal da população de Londrina, Paraná, em 2008. Dois mil cento e sessenta e dois indivíduos, residentes nas ruas selecionadas por meio de amostragem probabilística por conglomerados, foram entrevistados utilizando-se dois instrumentos: dados sócio-demográficos e Hábito Intestinal na População Geral (em sua versão adaptada e validada para o Brasil). No presente estudo, foram utilizadas as variáveis necessárias para o cálculo da prevalência de CI, de acordo com os Critérios de Roma III, e identificação dos fatores associados. Os dados foram analisados por meio do Teste de Qui-Quadrado (X²) de Pearson e regressão logística multivariada. Foram estimadas as prevalências de CI, com intervalos de confiança (IC) a 95%. As associações foram medidas pelo Odds Ratio ajustado, por análise de regressão. A prevalência total de CI foi 14,6%, sendo maior entre as mulheres (21,9%) comparativamente aos homens (5,3%), crescente com a idade em ambos os sexos e inversamente proporcional ao aumento da renda familiar. Para a amostra total de constipados (n=315), os fatores que apresentaram associação com CI foram: sexo feminino, baixa renda familiar, história de fístula, fissura anal, prolapso retal, hemorróidas, cirurgias anorretais, AVE e doenças do sistema nervoso. Para o sexo feminino, as variáveis significativamente associadas à CI foram: baixa renda familiar, história de fístula, fissura anal, cirurgia anorretal, trauma ou ferimento ao redor do ânus, retocele, hemorróidas e AVE. Para o sexo masculino, CI foi estatisticamente associada a: idade avançada, baixa renda familiar, fissura anal, cirurgia anorretal, AVE e doença do sistema nervoso. As variáveis baixa renda familiar, AVE, história de fissura anal e cirurgia anorretal permaneceram nos três modelos testados. Este estudo contribui para o conhecimento da epidemiologia da CI na população geral brasileira, ao constituir-se em um dos poucos estudos nacionais de base populacional sobre o tema. Além disso, os seus resultados agregam novos conhecimentos, ao terem sido testadas algumas variáveis que não são usualmente analisadas em estudos de base populacional sobre prevalência de CI na população geral, como fístula, fissura, cirurgias anorretais, hemorróidas, doenças do sistema nervoso, entre outros.Since the Rome Criteria were developed a lot of studies have been done to determine general constipation epidemiology. However, most of the studies consider only specific groups of people and only a few of them consider a general population analysis. The current study is a population-based study that aimed to estimate the prevalence of constipation in adults from the general population at Londrina city, Paraná State, Brazil and also to identify the clinical and demographic factors associated to occurrence of constipation in this population. This study is a secondary analysis from the epidemiological population-based study about bowel habit, that was descriptive and exploratory, cross sectional, and it was performed in 2008 at the urban area of Londrina city. Two thousand one hundred sixty two individuals living at the selected streets through cluster sampling were interviewed. Two instruments were used for data collection: social-demographic data and the adapted and validated version of Bowel Function in the Community for Brazil. In the current study the original database variables were used to calculate the prevalence of constipation, according to the Rome Criteria III, and also to determine the associated factors. The data were analyzed using chi-square test (X²) and multivariate logistic regression. The prevalence of constipation was estimated with a 95% confidence interval. The adjusted odds ratio was used to measure the association between variables, using regression analysis. The total prevalence of constipation was 14,6%, higher among women (21,9% women; and 5,3% men), growing with age in both genders, and inverse proportion to the family income. The factors that presented statistically significant association to the constipated sample (n=315) were: female gender, low social economic status, fistulae history, anal fissure, rectal prolapse, hemorrhoids, anus-rectal surgery, stroke and nervous system disease. Among the women, the statistically significant associated factors were: low social economic status, fistulae history, anal fissure, anus-rectal surgery, trauma or wound around the anus, rectocele, hemorrhoids, and stroke. Among the men, the statistically significant associated factors were: higher ages, low social economic status, anal fissure, anus-rectal surgery, stroke, and nervous system disease. The variables low social economic status, stroke, anal fissure history and anus-rectal surgery were statistically significant in all three tested statistical models. This study is important because it shows the epidemiology of constipation in the general Brazilian population, and it is one of the very few national based-population studies about the subject. It also shows associations between constipation and fistulae history, anal fissure, anus-rectal surgery, hemorrhoids, stroke, nervous system disease, and other factors that have not been often analyzed in based-population studies about prevalence of constipation

Topical application of cream containing nanoparticles with vitamin E for radiodermatitis prevention in women with breast cancer: a randomized pilot study

Introdução: Apesar da ação promissora dos agentes antioxidantes contra as radiodermatites, os estudos sobre esse tema ainda são pouco consistentes. Diante dessas considerações, questionou-se sobre a ação da vitamina E, veiculada por meio de nanotecnologia, na prevenção das radiodermatites. Objetivo: Avaliar o potencial efeito da aplicação tópica de creme com nanopartículas lipídicas contendo vitamina E, na concentração final de 2%, para a prevenção de radiodermatite aguda em mulheres com câncer de mama submetidas à teleterapia. Método: Estudo piloto randomizado e duplo cego, realizado em um hospital oncológico de Minas Gerais. A amostra foi constituída de 40 mulheres, divididas em três grupos: Intervenção - realizaram a aplicação tópica de creme com nanopartículas lipídicas contendo vitamina E; Controle 1 - realizaram a aplicação tópica de creme sem nanopartículas lipídicas e sem vitamina E; Controle 2 - realizaram a aplicação tópica de creme com nanopartículas lipídicas sem vitamina E. A incidência de radiodermatite, o grau (pelas escalas RTOG e CTCAE) e o tempo para o aparecimento da reação foram considerados desfechos primários; a qualidade de vida, a temperatura da mama e os sintomas relatados como desfechos secundários. Todas as participantes seguiram as orientações padrão para prevenção de radiodermatites, realizaram a aplicação de creme três vezes por dia e foram avaliadas três vezes por semana. Para a coleta dos dados, utilizaram-se quatro instrumentos: dados sócio-demográficos e clínicos, registro das avaliações periódicas, e avaliação da qualidade de vida relacionada à saúde (QVRS) EORTC-QLQ-30 e EORTC-QLQ-BR23. Os dados foram analisados por meio de: modelo ANOVA, teste de Kruskal-Wallis, qui-quadrado, exato de Fisher, modelo de riscos proporcionais de Cox e modelo de efeitos mistos. O projeto foi aprovado por Comitê de Ética em Pesquisa. Resultados: Todas as pacientes da amostra apresentaram radiodermatites em algum grau. As incidências de reações graus 1, 2 e 3 foram, respectivamente: 58%, 25% e 17% para o grupo Intervenção; 36%, 29% e 36% para o grupo Controle 1; e 50%, 43% e 7% para o grupo Controle 2. Não houve diferenças significativas entre os grupos do estudo no que concerne ao grau de radiodermatite, QVRS e temperaturas das mamas. Observou-se uma tendência para potencial efeito protetor do creme com nanopartículas contendo vitamina E no que concerne ao tempo para aparecimento da radiodermatite nas pacientes que não receberam a dose de boost (p=0,03) e ocorrência de eritema leve inframamário (p=0,04). Prurido foi reportado por 90% das mulheres, apresentando por mais tempo naquelas do grupo Intervenção (p=0,05). Os dados encontrados permitiram subsidiar o cálculo amostral para o ensaio clinico definitivo, que deverá ser composto de 108 pacientes. Conclusões: Observou-se um potencial efeito protetor do creme com nanopartículas contendo vitamina E com relação ao tempo para aparecimento da radiodermatite e ocorrência de eritema leve inframamário. Não foram observadas diferenças significativas entre os grupos do estudo com relação a incidência e intensidade de radiodermatites, QVRS e temperatura das mamas. Amostra constituída de 108 pacientes deverá compor o ensaio clínico definitivo para evidenciar as hipóteses levantadas neste estudo piloto.Introduction: Despite the promising action of antioxidant agents against radiodermatitis, studies on this topic are still poorly consistent. In view of these considerations, vitamin E transmitted through nanotechnology action on radiodermatitis prevention was questioned. Aims: To evaluate acute radiodermatitis prevention effect of topical application of a cream with lipid nanoparticles containing vitamin E (final concentration of 2%) in women with breast cancer submitted to radiotherapy. Method: Randomized, double blind pilot study performed at a cancer hospital in Minas Gerais. The sample consisted of 40 women, divided into three groups: Intervention - they performed topical application of the cream with lipid nanoparticles containing vitamin E; Control 1 - they performed topical application of the cream without lipid nanoparticles and without vitamin E; Control 2 - performed the topical application of cream with lipid nanoparticles without vitamin E. The incidence of radiodermatitis, the classification (by the RTOG and CTCAE scoring systems) and the time for appearance of the reaction were considered primary outcomes; quality of life, breast temperature and symptoms reported as secondary outcomes. All participants followed the standard guidelines for the prevention of radiodermatitis, performed the application of cream three times a day and were evaluated three times a week. Four instruments were used to collect data: socio-demographic and clinical data, record of periodic evaluations, and health-related quality of life assessment (HRQoL) - EORTC-QLQ-30 and EORTC-QLQ-BR23. The data were analyzed by means of: ANOVA model, Kruskal-Wallis test, chi-square test, Fisher\'s exact test, Cox proportional hazards model and mixed effects model. The project was approved by the Research Ethics Committee. Results: All patients in the sample presented radiodermatitis to some degree. The incidence of grade 1, 2 and 3 reactions were, respectively: 58%, 25% and 17% for the intervention group; 36%, 29% and 36% for the Control 1 group; and 50%, 43% and 7% for Control group 2. There were no significant differences between the study groups regarding the degree of radiodermatitis, HRQoL and breast temperatures. There was a trend towards a potential protective effect of the cream with vitamin E-containing nanoparticles regarding the time to onset of radiodermatitis in patients who did not receive the boost dose (p = 0.03) and the occurrence of mild inframammary erythema (p = 0.04). Pruritus was reported by 90% of the women, presenting more time in the Intervention group (p = 0.05). The colected data allowed to calculate the sample size for the definitive clinical trial, which should be composed of 108 patients. Conclusions: It was observed a potential protective effect of the cream with nanoparticles containing vitamin E concerning to the time of radiodermatitis appearance and the occurrence of inframammary light erythema. There were no significant differences between the study groups regarding the incidence and intensity of radiodermatitis, HRQoL and breast temperature. A sample consisting of 108 patients should compose the definitive clinical trial to highlight the hypotheses raised in this pilot study

Prevalence of self-reported constipation in adults from the general population

OBJECTIVE To estimate the prevalence of self-reported constipation and associated factors in the general population of a Brazilian city. METHOD Secondary analysis of an epidemiological study, population-based, cross-sectional study, about bowel habits of Brazilian population. A total of 2,162 individuals were interviewed using two instruments: sociodemographic data and the adapted and validated Brazilian version of the "Bowel Function in the Community" tool. RESULTS There was a prevalence of 25.2% for the self-reported constipation, 37.2% among women and 10.2% among men. Stroke and old age were associated with constipation in the three statistical models used. CONCLUSION The prevalence found showed to be similar to the findings in the literature, although some associated factors obtained here have never been investigated
