ZINGIBER OFFICINALE (GENGIBRE) NA ÊMESE GRAVÍDICA: uma breve revisão narrativa

Hyperemesis gravidarum is the occurrence of uncontrollable vomiting during pregnancy, resulting in dehydration, weight loss and ketosis, this is mainly due to hormonal and emotional changes that take place during pregnancy. However, hyperemesis can also occur due to cytokines circulating in the maternal blood, vitamin B6 deficiency, allergic or gastrointestinal reaction. In this study, a literature review of the narrative type was adopted as a methodological strategy, due to the possibility of accessing research by other authors on the topic addressed, allowing the gathering of these experiences and reports, based on the researcher's understanding. Some studies have evaluated ginger as an effective and safe treatment for nausea and vomiting in the context of pregnancy. Here, we provide an update and analysis of the use of ginger in preventing nausea and vomiting in emesis gravidarum. It would be interesting to conduct preclinical studies to understand the effectiveness of the main constituents of ginger, including gingerols and shogaols. For greater safety purposes, the risk and benefit of use should be assessed and attention to possible drug interactions.La hiperemesis gravídica es la aparición de vómitos incontrolables durante el embarazo, que resultan en deshidratación, pérdida de peso y cetosis, esto se debe principalmente a cambios hormonales y emocionales que se producen durante el embarazo. Sin embargo, la hiperemesis también puede ocurrir debido a citocinas que circulan en la sangre materna, deficiencia de vitamina B6, reacción alérgica o gastrointestinal. En este estudio se adoptó una revisión de la literatura de tipo narrativo debido a la posibilidad de acceder a investigaciones de otros autores sobre este tema, sin delimitar las fechas de publicación. En esta revisión, se presentaron los mecanismos farmacológicos, la descripción fitoterapéutica, la eficacia y la seguridad de Zingiber officinale para la emesis gravídica. Los estudios consultados, en particular los ensayos clínicos aleatorizados, demostraron la eficacia y seguridad de Zingiber officinale durante el embarazo a una dosis máxima de 1000 g diarios de extracto seco. A pesar de esto, el profesional que prescribe debe ser consciente de la evaluación de riesgos y beneficios del uso, además de las posibles interacciones medicamentosas y reacciones adversas.Hiperêmese gravídica é a ocorrência de vômitos incontroláveis durante a gestação, resultando em desidratação, perda ponderal e cetose, isso acontece principalmente devido às alterações hormonais e emocionais que acontecem durante a gravidez.

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.

oai:omp.abpeducom.org.br:publicationFormat/1O material aqui divulgado representa, em essência, a contribuição do VII Encontro Brasileiro de Educomunicação ao V Global MIL Week, da UNESCO, ocorrido na ECA/USP, entre 3 e 5 de novembro de 2016. Estamos diante de um conjunto de 104 papers executivos, com uma média de entre 7 e 10 páginas, cada um. Com este rico e abundante material, chegamos ao sétimo e-book publicado pela ABPEducom, em seus seis primeiros anos de existência. A especificidade desta obra é a de trazer as “Áreas de Intervenção” do campo da Educomunicação, colocando-as a serviço de uma meta essencial ao agir educomunicativo: o diálogo intercultural, trabalhado na linha do tema geral do evento internacional: Media and Information Literacy: New Paradigms for Intercultural Dialogue

The revised topics include glasses, sol–gel, light-emitting diodes, nanoparticles, metal–organic frameworks, coordination polymers, thin films, energy transfer processes, upconversion and development of new theoretical tools. The important role played by Prof. Oscar L. Malta on this subject is evidenced by his many contributions to the broad range of investigations reported here and this review is dedicated to him, on the occasion of his 60th birthday

Canine visceral leishmaniasis : detection of Leishmania spp. genome in peripheral blood of seropositive dogs by real-time polymerase chain reaction (rt-PCR).

Visceral leishmaniasis (VL) is a zoonosis caused by the protozoa of the genus Leishmania. Among the species, L. infantum and/or L. infantum (chagasi) are the most important species affecting the Americas. Domestic dogs are the main reservoir of the parasite and participate effectively in the parasite' transmission cycle. The Canine Visceral Leishmaniasis Control Program (PCLV) adopted in Brazil present as strategies the vector control, health education and serological diagnosis of CVL in dogs followed by culling of the seropositive ones. The resolution to eliminate seropositive dogs by euthanasia, when necessary, are the most controversial and least accepted by society. The diagnostic methods for canine visceral leishmaniasis, currently indicated and approved in Brazil by the Ministry of Health from Brazil are the Dual Path Platform (DPP)? as a screening test and the Enzyme immunoassay test (ELISA?). This study aimed to verify the presence of Leishmania spp. DNA in peripheral blood samples of dogs presenting positive serological results byDPP? and ELISA? tests,throughreal-time polymerase chain reaction (rt-PCR), using the pair of primers 150?152 already described. For this purpose, were collected blood samples from 185 seropositive dogs among them, 41 (22%) exhibited some clinical signal of disease, whereas 144 (78%) was asymptomatic. The animals were also analyzed according to gender, race and hair size. According to the results of rt-PCR, it was observed that among the185 seropositive dogs analyzed, only 132 (71%) presented positive results for CVL and 53 (29%) presented negative results. From this, 41/41 symptomatic dogs were positive (100%), while among the asymptomatic dogs, 91/144 were positive (63, 2%) and 53/144 were negative (36, 8%). Concerning the hair size of seropositive dogs, we found that 41 (22%) had long hair, while 144 (78%) had short hair. No statistical significance occurred between the results of rt-PCR, ELISA and DPP tests and the profile of the animals (gender, size of the dogs and hair size), probably due to the small number of samples and the sampling differences of each profile. But statistical significance occurred between the results of rt-PCR and the clinical evaluation, since the rt-PCR was positive in all symptomatic dogs. Thus, through these results, we reached at the following question, which may contribute to an important current debate: the dogs presenting CVL seropositive diagnosis confirmed by tests distributed by the Ministry of Health were in reality ill or were they seropositive by living in an endemic area of the disease? Would these asymptomatic seropositive dogs spread the disease to the inhabitants even presenting a low parasite charge circulating in the blood
