BackgroundAlthough sickle cell disease is an important public health problem in Brazil, there is a gap in the literature on the level of knowledge of primary health care professionals about the treatment and management of sickle cell disease. Therefore, this study aimed to evaluate the level of knowledge about sickle cell disease of physicians and nurses who work in the Family Health Program in a region of Brazil with a high prevalence of this disease.MethodsThis is a descriptive, cross-sectional study conducted at the municipality of Montes Claros, in the north of Minas Gerais, Brazil. Study participants included 96 physicians and nurses who work at the Family Health Program in an urban area of the city. Data was collected using an original, partially tested questionnaire based on health care check points for children with sickle cell disease established in educational protocols from the State Health Secretary of Minas Gerais and the Ministry of Health. The structured questionnaire contained 47 questions addressing three axes: epidemiology (8 questions); clinical manifestations (13 questions); and management of children with sickle cell disease (26 questions). Knowledge was measured through mean correct responses to proposed questions. Ethical principles were respected and this project was approved by the Committee of Ethics in Research.Results59.4% (57) of the study participants were nurses and 40.6% (39) were physicians. The median length of training and median length of service in primary health care were 4.3 (2.8-8.0) years and 4.0 (2.0-7.1) years, respectively. The mean performance in knowledge tests was < 75%, with 5.7/8 (SD = 1.4) for the "epidemiology" questions; 8.6/13 (SD = 2.2) for "clinical manifestations"; and 17.0/26 (SD = 2.9) for "management of children with sickle cell disease" questions; resulting in a mean total of 31.4/47 (SD = 5.10) correct responses. A statistically significant association was found between the number of correct responses and family health care qualifications (p = 0.015).ConclusionThere is an urgent need to improve primary health care professional training in the care of children with sickle cell disease.

<p>No Brasil, a produção de flores tem crescido, ganhando importância econômica principalmente de crisântemos (<em>Dendranthema grandiflora</em>), que respondem por aproximadamente 80% do mercado interno de flores. Para a produção de mudas visando a plantas de boa qualidade, o substrato é fator básico, sobretudo no caso de culturas de propagação vegetativa. O objetivo deste trabalho foi avaliar quatro tipos de substratos, bem como o efeito do promotor de crescimento no enraizamento de estacas de crisântemo. O experimento foi conduzido em ambiente protegido, utilizando-se o delineamento em blocos casualizados, em esquema fatorial 4x2, com quatro repetições e duas mudas por repetição. Os fatores foram quatro substratos (S1 - 100% de substrato comercial Topstrato Hortaliças®; S2 - 50%, em medida de volume, de substrato comercial misturado com 50% de solo franco argiloso; S3 - 55% de solo franco argiloso misturado com 15% de areia lavada, 15% de esterco bovino curtido e 15% de maravalha seca em base volume; S4 - 25% de solo franco argiloso misturado com 25% de areia lavada, 25% de esterco bovino curtido e 25% de maravalha seca, em medida de volume), com e sem o pré-tratamento das estacas com promotor de crescimento vegetal Stimulate®, visando a produzir mudas de crisântemo da cultivar Dobrado Sortido. Uma estaca contendo 5 folhas foi plantada em tubete plástico coberto com um telado negro de 50% de sombra e irrigado diariamente, 4 vezes ao dia. Ao final do período experimental, as mudas foram colhidas e as variáveis de crescimento, avaliadas. As análises de variância apresentaram efeito significativo (p ? 0,01) dos substratos na altura de planta (AP) e no comprimento de raiz (CR). Os melhores resultados foram alcançados com o substrato S2, que mostrou valores de AP 12,10; 31,45 e 30,24 e CR 2,75; 18,81 e 14,16% maiores quando comparado com os substratos S1, S3 e S4, respectivamente. Por outro lado, as estacas sem pré-tratamento com Stimulate® mostraram melhor crescimento, apresentando efeitos significativos (p ? 0,05) no número de folhas e massas de matérias fresca e seca da parte aérea, raiz e total.</p>

“…Since in summer season the quantity of sunlight hours is higher in subtropical areas, herbaceous cuttings under these conditions are favored by higher production of photosynthesized compounds (Hussain et al, 2017). The influences of the season of the year on root induction also can be caused by the nutrients reserve in the cambial tissues and the cambial activity, as well by the endogenous auxins presence in the cuttings or cuttings stage of development (Leite & Martins, 2007).…”

The cultivation of temperate fruits such as blueberries is expanding in Brazil. However, lower technical information on plant cultivation and difficulties in propagation are among the limiting factors in the expansion of the blueberry cultivation. The objective of this study was to evaluate the influence of different methods of indole butyric acid (IBA) application on the rooting of 'Brite Blue' blueberry herbaceous cuttings, with and without lesions, collected in two different seasons. The experimental design was completely randomized, with five replicates, each consisting of 10 cuttings, in a 3x2x2 factorial arrangement. Two IBA application methods (talc and alcohol) and control (no application), with two collection seasons (autumn and summer), and cuttings with and without basal injury, consisted of two superficial cuts on the basal part, on opposite sides, were evaluated. The cuttings were put in carbonized rice husk substrate, inside perforated plastic boxes (44x30x7 cm), and maintained in a mist chamber with intermittent regime. After 200 days, it was verified that the 'Brite Blue' blueberry was influenced by the cutting collection season, with higher rooting percentage when basal lesion was performed in cuttings collected in the summer. The IBA application of 1000 mg L-1 does not influence the rooting and root development of the cuttings.
