Monteverdia ilicifolia: um protetor gástrico / Monteverdia ilicifolia: a gastric protector / Monteverdia ilicifolia: protector gástrico

Monteverdia ilicifolia, conhecida popularmente como espinheira-santa, é uma planta da família Celastraceae de relevante ação terapêutica devido às suas propriedades medicinais, principalmente a sua atividade gastroprotetora, possuindo efeitos comprovados sobre acidez e úlceras estomacais. Desta forma o objetivo deste trabalho foi encontrar na literatura evidências para o uso terapêutico da M. ilicifolia, como uma alternativa frente aos fármacos sintéticos disponíveis na indústria farmacêutica voltados para o tratamento de problemas estomacais. Foi utilizado no presente trabalho a base de dados Google acadêmico. Os distúrbios estomacais afetam milhares de pessoas, influenciando de forma negativa na qualidade de vida da população e gerando prejuízos ao sistema de saúde. Os fármacos com atividade sobre a secreção da acidez gástrica são as medicações mais prescritas para essas enfermidades, destacando-se os antagonistas do receptor H2 de histamina e os inibidores da bomba de prótons, amplamente utilizados para o tratamento de úlceras e gastrite. Com o tempo, esses medicamentos passaram a ser indiscriminadamente utilizados, prática que põem em risco a saúde íntegra dos pacientes, mediante aos diversos efeitos adversos que esses medicamentos podem causar. As plantas medicinais têm sido aplicadas na terapia de diversas doenças em toda a história da humanidade. Nesse contexto, a espinheira-santa surge como uma alternativa segura e eficaz para a prevenção e tratamento dessas patologias. Dentre os compostos bioativos que podem desempenhar a atividade gastroprotetora, destacam-se os taninos, triterpenos e flavonóides. Os estudos analisados demonstram que a M. ilicifolia possui relevante ação terapêutica, com potencial para substituir os fármacos usualmente empregados no tratamento de úlceras e gastrite.

The Monteverdia ilicifolia, popularly known as espinheira-santa, is a plant of the Celastraceae's family with relevant therapeutic action due to its medicinal properties, mainly its gastroprotective activity, and possesses proven effects on acidity and stomach ulcers. The aim of this work was to find in the literature evidence for the therapeutic use of M. ilicifolia, as an alternative to the synthetic drugs available in the pharmaceutical industry for the treatment of stomach problems. The academic Google database was used in this work. Stomach disorders affect thousands of people, negatively influencing the population's quality of life and causing damage to the health system. The drugs with activity on gastric acid secretion are the most prescribed medications for these diseases, especially histamine H2 receptor antagonists and proton pump inhibitors, widely used for the treatment of ulcers and gastritis. Over time, these drugs began to be used indiscriminately, a practice that jeopardizes the health of patients, due to the various adverse effects that these drugs can cause. Medicinal plants have been applied in the therapy of various diseases throughout human history. In this context, the espinheira-santa emerges as a safe and effective alternative for the prevention and treatment of these pathologies. Among the bioactive compounds that can perform a gastroprotective activity, tannins, triterpenes, and flavonoids stand out. The analyzed studies demonstrate that M. ilicifolia has relevant therapeutic action, with the potential to replace the drugs usually used in the treatment of ulcers and gastritis.

Do climate changes alter the distribution and transmission of malaria? Evidence assessment and recommendations for future studies.

Malaria, a mosquito-borne infectious disease, is considered a significant global health burden. Climate changes or different weather conditions may impact infectious diseases, specifically those transmitted by insect vectors and contaminated water. Based on the current predictions for climate change associated with the increase in carbon dioxide concentrations in the atmosphere and the increase in atmospheric temperature, the Intergovernmental Panel on Climate Change predicts that in 2050, malaria may threaten some previously unexposed areas worldwide and cause a 50% higher probability of malaria cases. Climate-based distribution models of malaria depict an increase in the geographic distribution of the disease as global environmental temperatures and conditions worsen. Researchers have studied the influence of changes in climate on the prevalence of malaria using different mathematical models that consider different variables and predict the conditions for malaria distribution. In this context, we conducted a mini-review to elucidate the important aspects described in the literature on the influence of climate change in the distribution and transmission of malaria. It is important to develop possible risk management strategies and enhance the surveillance system enhanced even in currently malaria-free areas predicted to experience malaria in the future.

Flebotomíneos de localidades rurais no noroeste do Estado do Paraná, Brasil / Sandflies in rural localities in northwest Paraná State, Brazil

Relatam-se os resultados de coletas de flebotomíneos em seis lotes na zona rural no Município de Japurá, Estado do Paraná, Brasil, mostrando a presença de flebotomíneos no domicílio, peridomicílio e em matas residuais. As coletas de flebotomíneos foram realizadas com armadilhas de Falcão, das 20:00h às 03:00h. Nos lotes 195, 223, 236 e 527 foram feitas três coletas em diferentes períodos, de dezembro de 2007 a janeiro de 2009. Nos lotes 175 e 218, as coletas foram feitas de janeiro a dezembro de 2008. Coletaram-se 8.453 flebotomíneos, com uma média horária (MH) de 155,40 exemplares. Nyssomyia neivai foi a espécie dominante. A maioria dos flebotomíneos foi coletada em abrigos de animais domésticos (MH = 75,91) e nas matas ciliares (MH = 38,45), nos meses mais quentes e chuvosos, num ambiente peridomiciliar com acúmulo de matéria orgânicas e descarte inadequado de águas de uso doméstico, o que mostra a necessidade da limpeza regular do peridomicílio e do afastamento dos abrigos de animais domésticos das residências.

This study reports the results from sandfly captures at six sites in a rural area of Japurá, Paraná State, Brazil, showing the vector's presence indoors, outdoors, and in residual forest. Sandfly captures were performed with Falcão traps from 8:00 AM to 3:00 PM. At sites 195, 223, 236, and 527, three captures were performed at different times from December 2007 to January 2009. At sites 175 and 218, captures were performed from January to December 2008. 8,453 sandflies were captured, with an average of 155.40 specimens per hour. Nyssomyia neivai was the predominant species. Most sandflies were captured in domestic animal shelters (75.91 per hour) and in ciliary forest (38.45 per hour) during the hottest and rainiest months, in the outdoor environment with accumulation of organic matter and inadequate disposal of household wastewater. The study emphasizes the need for regular outdoor cleaning around households and building domestic animal shelters far from residences.
