Communication of bad news in medical practice: medical perception on facilitators and hinderers

OBJETIVOS: Conhecer a formação de médicos no que diz respeito à comunicação de notícias difíceis e conhecer os dificultadores e facilitadores na prática desse profissional em comunicar notícias difíceis a pacientes e seus familiares. MÉTODOS: Estudo qualitativo descritivo. Coleta de dados realizada em entrevista semiestruturada, com profissionais médicos de uma unidade oncológica. Análise de conteúdo convencional realizada segundo Hsie e Shannon. RESULTADOS Houve diferentes definições do termo notícia difícil pelos entrevistados, e diversos fatores dificultadores e facilitadores para a comunicação dessas notícias. Esses fatores podem ser técnicos e/ou sócio-emocionais. Sujeito a esses fatores, está o próprio sucesso da comunicação, que interfere no tratamento do paciente. CONCLUSÃO: Alguns fatores de influência são inalteráveis, outros são passíveis de mudança ou prevenção. Entre esses, estão a atuação multidisciplinar, uma boa relação médico-paciente e um ambiente adequado para a comunicação. Quando esses fatores são manipulados para uma melhor comunicação, essa é realizada com maiores sucesso e benefício. O preparo prévio para essa comunicação foi unanimemente realçado, justificando uma maior abordagem na formação acadêmica médica sobre esse assunto.OBJECTIVES: to acknowledge the training of physicians regarding the disclosure of bad news and the difficulties and facilitators into the practice of communicating difficult news to patients and families. METHOD: descriptive qualitative study. Data collection was carried out through a semi-structured interview with medical professionals from an oncology unit. Conventional content analysis performed according to hsie and shannon. RESULTS: it was reported a great precariousness in medical education regarding the communication of bad news, being a possible contributor to the difficulties found in the position of communicator. There were different definitions attributed to the term “bad news” by the interviewees and several factors that made it difficult to communicate those news. These factors may be technical and/or socio emotional. Subject to these factors, is the very success of communication, that interferes with the treatment of the patient. CONCLUSION: some influencing factors are non-changeable; others are subject to change or prevention. Among these, are the multidisciplinary work, a good doctor- patient relationship and a suitable environment for communication. When these factors are manipulated for a better communication, it is accomplished with greater success and benefit. The prior preparation for this communication was unanimously highlighted, justifying a greater approach in academic medical education on this subject

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Validação de metodologia espectrofotométrica para quantificação dos flavonóides de Bauhinia cheilantha (Bongard) Steudel

Os laboratórios de fitoterápicos necessitam de metodologias que assegurem o controle de qualidade de seus produtos quando os mesmos não constam em farmacopéias ou monografias oficiais. Baseando-se neste fato, o presente estudo visou validar uma metodologia analítica para quantificação de flavonóides contidos nos extratos da pata-de-vaca (Bauhinia cheilantha [Bongard] Steudel), através de espectrofotometria no visível, como equivalentes de Rutina (µg/mL). Todos os parâmetros exigidos pela ANVISA foram avaliados. No teste de especificidade, observou-se a existência de pico máximo a 420 nm. O método foi considerado linear e com alta sensibilidade de quantificação (2,51 µg/mL). O método também mostrou-se robusto e com elevada recuperação (98,36%). Os resultados obtidos para repetibilidade (intra-corrida), precisão intermediária (inter-corridas) e reprodutibilidade certificaram a precisão do método com valores entre 0,31 e 3,58%, sendo também considerado exato (95,71-105,50%). Com este estudo, o método proposto foi considerado específico, preciso, reprodutível, exato, de baixo custo e fácil execução.Phytotherapeutic laboratories require access to methodologies that guarantee quality control for their products when these items are not already registered in pharmacopeias or official monographs. As such, the present study sought to validate analytical methodologies for quantifying natural flavonoids contained in extracts of "pata-de-vaca" (Bauhinia cheilantha [Bong.] Steudel) using visible light spectrophotometry and a rutin standard (µg/ml). All of the parameters required by ANVISA were evaluated. The specificity test revealed a maximum absorption peak at 420 nm. The methodology was considered linear and of high quantification sensitivity (2.51 µg/ml). The methodology also proved to be robust, and had high recovery levels (98.36%). The results obtained for repeatability, intermediate precision (intra- and inter-day), and reproducibility all certified the precision of the method, with values between 0.31 and 3.58%; the methodology was also considered exact (95.71-105.50%). This study demonstrated that the proposed methodology can be considered specific, precise, reproducible, exact, of low cost, and easy to perform

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
