The genus Bauhinia popularly known as "pata-de-vaca", "unha de vaca", "unha de boi", "unha de anta" e "casco de vaca" is widely used in the form of teas and other herbal preparations. The aim of this literature review was to show the diversity and biological potential of Bauhinia species for health promotion. A search was carried out for articles listing some species of medical interest. The pharmacological activities of B. forficata were also highlighted in articles published in the last twenty years using the PubMed database. Research has shown that Bauhinia is used as a hypoglycemic and antidiabetic agent, diuretic, cholesterol reducer, in the treatment of cystitis, intestinal parasites, elephantiasis, tumors and other ailments, including infections and painful processes. In the last eleven years, 86% of the works carried out with B. forficata used the plant collected or acquired in Brazil, predominantly publications from the southern region of the country where almost 60% reported activity on diabetes and its complications and/or antioxidant effect. Despite the literature pointing out the great medicinal potential of Bauhinia in chronic diseases and their complications, there is still a need for more translational research.

[Methodological aspects of integrated care pathways]. / Aspectos metodológicos de los procesos asistenciales integrados (PAI).

An Integrated Healthcare Pathway (PAI) is a tool which has as its aim to increase the effectiveness of clinical performance through greater coordination and to ensure continuity of care. PAI places the patient as the central focus of the organisation of health services. It is defined as the set of activities carried out by the health care providers in order to increase the level of health and satisfaction of the population receiving services. The development of a PAI requires the analysis of the flow of activities, the inter-relationships between professionals and care teams, and patient expectations. The methodology for the development of a PAI is presented and discussed in this article, as well as the success factors for its definition and its effective implementation. It also explains, as an example, the recent PAI for Hypoglycaemia in patients with Type 2 Diabetes Mellitus developed by a multidisciplinary team and supported by several scientific societies.

Risk factors for unstable blood glucose level: integrative review of the risk factors related to the nursing diagnosis / Risco de glicemia instável: revisão integrativa dos fatores de risco do diagnóstico de enfermagem / Riesgo de nivel de glucemia inestable: revisión integradora de los factores de riesgo del diagnóstico de enfermeira

ABSTRACT Objective: to identify evidence in the literature on the possible risk factors for the risk of unstable blood glucose diagnosis in individuals with type 2 diabetes mellitus, and to compare them with the risk factors described by NANDA International. Method: an integrative literature review guided by the question: what are the risk factors for unstable blood glucose level in people with type 2 diabetes mellitus? Primary studies were included whose outcomes were variations in glycemic levels, published in English, Portuguese or Spanish, in PubMed or CINAHL between 2010 and 2015. Results: altered levels of glycated hemoglobin, body mass index>31 kg/m2, previous history of hypoglycemia, cognitive deficit/dementia, autonomic cardiovascular neuropathy, comorbidities and weight loss corresponded to risk factors described in NANDA International. Other risk factors identified were: advanced age, black skin color, longer length of diabetes diagnosis, daytime sleepiness, macroalbuminuria, genetic polymorphisms, insulin therapy, use of oral antidiabetics, and use of metoclopramide, inadequate physical activity and low fasting glycemia. Conclusions: risk factors for the diagnosis, risk for unstable blood glucose level, for persons with type 2 diabetes mellitus were identified, and 42% of them corresponded to those of NANDA International. These findings may contribute to the practice of clinical nurses in preventing the deleterious effects of glycemic variation.

Evaluación etnofarmacológica de plantas con propiedades hipoglucémicas usadas en la medicina tradicional del sureste de México / Ethnopharmacological evaluation of plants with hypoglycemic properties used in traditional medicine of México southeast

Ante el incremento de enfermedades crónico-degenerativas como la Diabetes mellitus (DM), es necesario e indispensable documentar y evaluar farmacológicamente las plantas utilizadas en la medicina tradicional regional para el control empírico de esta enfermedad. Este estudio presenta los resultados de una investigación etnofarmacológica de especies vegetales empleadas empíricamente en una comunidad del sureste mexicano para el control de la DM. La información se obtuvo en una comunidad de Tabasco, México a través de una entrevista estructurada TRAMIL y mediante la consulta de ejemplares de herbario. Se encontró un total de 36 especies vegetales usadas en la comunidad para este tratamiento y todas ellas conocidas por uno o más nombre locales. Las familias más representadas son las Fabaceae, Asteraceae, Cucurbitaceae, Meliaceae y Poaceae. Destacan cinco especies por su uso significativo TRAMIL (UST) para el control de la DM, siendo las más importantes Tradescanthia spathacea Sw. y Manilkara zapota (L.) P. Royen. La importancia de uso en la comunidad enfatiza la necesidad de iniciar estudios farmacológicos sobre la actividad hipoglucémica de estas especies.

Because of the increase of chronic degenerative diseases, such as Diabetes mellitus (DM), it is necessary and indispensable to carry out pharmacological studies in order to identify and to evaluate plant species that are used in regional traditional medicine for empirical control of DM. Results of an ethnopharmacological research on Mexican plants used for empirical control of DM in a community at the southeast of Mexico are presented in this study. Information was obtained from people at a community of Tabasco, Mexico by means of applying a TRAMIL structured interview, and by reviewing herbarium specimens. A total of 36 plant species that are used in the community to control the DM was found, all of those species are known by one or more local names. Botanical families with more species mentioned by people are Fabaceae, Asteraceae, Cucurbitaceae, Meliaceae and Poaceae. On the basis of their high TRAMIL significant use (TSU), five plant species are distinguished for local DM control, and two of them are the most important: Tradescanthia spathacea Sw. and Manilkara zapota (L.) P. Royen. The importance of using those species in the community emphasizes the need to initiate pharmacological studies on the hypoglycemic activity of them.

Defectos de la oxidación de ácidos grasos como causa de hipoglucemia no cetósica en el niño / Fat acid oxidation defects produce nonketotic hypoglycemia in childhood

Fatty acid oxidation defects (FAOD) cause a group of inherited metabolic diseases that impair mitochondrial energy production from lipids. The clinical presentation includes hypoketotic hypoglycaemia, acute liver failure, myocardiopathy and myopathy after a prolonged fasting. Inheritance is autosomal recessive and the global incidence is 1:10.000 newborn, varying between 1:9.000 and 1:60.000 newborns for medium-chain acyl-CoA dehydrogenase deficiency (MCAD), the most frequent FAOD. Therapy is dietary and pharmacological. As soon as the diagnosis is confirmed enough glucose to prevent lipolysis must be introduced, especially in the neonatal period and during metabolic derangements caused by infections. Nutritional treatment consists in avoiding any period of fasting by giving carbohydrate supplement when appetite is diminished, which is easy and inexpensive to do. The prognosis with presymptomatic diagnosis is excellent when done with a blood sample obtained in the neonatal period and analysed by tandem mass spectrometry, and when treatment is started immediately.

Los defectos de oxidación de los ácidos grasos corresponden a un grupo de alteraciones metabólicas hereditarias que afectan la producción intramitocondrial de energía a partir de los lípidos. Clínicamente se expresan con hipoglucemia no cetósica, insuficiencia hepática aguda, miocardiopatía o miopatía desencadenada por un ayuno prolongado. La herencia es autosómica recesiva y su frecuencia global se estima en 1:10.000 recién nacidos (RN), y entre 1 por 9 000 a 1 por 60 000 RN para el déficit de acil-CoA deshidrogenasa de cadena media (abreviado MCAD) defecto más frecuente en este grupo de patologías. Las medidas terapéuticas pueden ser dietéticas y farmacológicas. Una vez establecido el diagnóstico diferencial del tipo de defecto, es importante proporcionar suficiente cantidad de glucosa para prevenir la lipólisis del tejido adiposo, siendo fundamental en el período neonatal y las en descompensaciones metabólicas por infecciones. El tratamiento es fácil de aplicar y de bajo costo y consiste en fraccionar la alimentación para evitar el ayuno prolongado. El pronóstico es excelente cuando el diagnóstico es presintomático, a través del análisis de una muestra de sangre en papel filtro, para el estudio de acilcarnitinas por espectrometría en tandem durante el período de RN e iniciando el fraccionamiento de la dieta inmediatamente.
