Different words for stroke: the same concept? an analysis of associated symptoms and intended reaction in Brazil.

BACKGROUND: Different names for stroke might mislead physicians and emergency medical service workers. This study aimed to assess the different words for stroke in Brazil and both intended response and related symptoms associated with those names. METHODS: Cross-sectional study enrolling healthy individuals from urban areas in Northeast of Brazil for an open-ended survey. We presented a typical clinical case of a stroke (an elderly who had sudden onset of hemiparalysis and slurred speech) and asked "what is happening?", "what would you do?" and "which other symptoms could happen in this condition?". RESUTS: From 1,475 interviewed individuals, 1,220 (82,7%) recognized the scenario as a stroke. There were 3 words to correctly identify (based on correct intended response and spontaneously evoked associated symptoms) the stroke, which were "AVC" (acronym for cerebrovascular accident, in Portuguese), "derrame" (spillage) and "trombose" (thrombosis). There were significant differences among them concerning demographic, economic, educational and geographical aspects, but there was no difference according to the intended reaction among them. The most cited associated symptoms (excluding those present in the case) were impaired consciousness (10.6%), headache (8.9%) and dysesthesia (7.7%). "Aneurisma" (aneurism) was also cited, by 3 individuals. CONCLUSION: There are at least three words for stroke in Portuguese ("AVC", "derrame" and "trombose"); they were similar in terms of correct intended responses and spontaneously cited accompanying symptoms. Stroke campaigns should apply different names to reach a broader audience and to improve stroke recognition.

Recognition, reaction, risk factors and adequate knowledge of stroke: A Brazilian populational survey.

INTRODUCTION: General population proper knowledge about stroke can improve stroke outcomes. We aimed to assess the awareness levels of laypeople regarding stroke recognition, reaction, risk factors, and adequate general knowledge (correct answers for those three questions) of stroke. METHODS: Cross-sectional survey-based study enrolling community population from 12 cities of Brazil's Northeast. The volunteers were verbally exposed to a typical case of stroke and then responded to an open-ended semi-structured questionnaire to evaluate their stroke knowledge. RESULTS: A total of 1475 subjects enrolled in this study (52.6% of women, mean±SD 36.2±15.3 years-old, 13.0±4.4 years of formal schooling). 1220/1475 (82.7%) recognized the situation as a stroke; 1148/1475 (77.8%) would react to it by taking the patient to the emergency department or calling for emergency medical assistance; 844/1475 (57.2%) knew at least one risk factor; and 190/1475 (12.9%) stated that symptoms could be reversed if the patient was treated "as soon as possible". Adequate general knowledge was found in 622/1475 (42,2%) of participants. Notably, among those who recognized the stroke, 19.9% (243/1220) would not react appropriately to it. The multivariate analysis showed that factors independently related to stroke recognition were female sex, higher education levels, private health insurance and previous experience with a similar situation. Adequate general knowledge was associated with longer school years and health insurance. CONCLUSIONS: The frequency of stroke recognition and appropriate reaction were acceptable, however the general knowledge, knowledge of risk factors and notion that stroke treatment is time-sensitive were insufficient. Addressing the recognition-reaction gap requires targeted campaigns focusing on stroke treatment awareness.

Medicinal plants and diabetes: an ethnopharmacological study in Brazilian Northeast / Plantas medicinales y diabetes: un estudio etnofarmacológico en el noreste brasileño

Despite access to conventional medical therapies, the use of complementary medicine is increasing in many communities. The present study aimed to evaluate the popular knowledge of medicinal plants used to treat diabetes and its co-morbidities, in four rural communities in the municipality of Vitória de Santo Antão, in the Brazilian State of Pernambuco. The relative importance of a particular medicinal plant was calculated based on the percentage of mentions (IR%). The similarity between the communities was quantified using the Sørensen index (Ss). Interviews were conducted with 141 patients, of these, 83 reported use of medicinal plants as an alternative treatment. Overall there were 186 mentions, covering 61 ethnospecies. In relation to IR%, Mentha × villosa presented the highest value.Knowing the factors that influence selection of medicinal plants sheds light on the mechanisms through which patterns of use develop and this may help to preserve this knowledge.

A pesar del acceso a las terapias médicas convencionales, el uso de la medicina complementaria está aumentando en muchas comunidades. El presente estudio tuvo como objetivo evaluar el conocimiento popular de las plantas medicinales utilizadas para el tratamiento de la diabetes y sus comorbilidades, en cuatro comunidades rurales del municipio de Vitória de Santo Antão, en el estado brasileño de Pernambuco. La importancia relativa de una planta medicinal en particular se calculó en base al porcentaje de menciones (% de IR). La similitud entre las comunidades se cuantificó mediante el índice de Sørensen (Ss). Se realizaron entrevistas con 141 pacientes, de estos, 83 informaron el uso de plantas medicinales como tratamiento alternativo. En total hubo 186 menciones, cubriendo 61 etnoespecies. En relación al% de RI, Mentha × villosa presentó el valor más alto. Conocer los factores que influyen en la selección de plantas medicinales arroja luz sobre los mecanismos a través de los cuales se desarrollan los patrones de uso y esto puede ayudar a preservar este conocimiento.
