Silicon mitigates nutritional stress in quinoa (Chenopodium quinoa Willd.).

Nutritional deficiency is common in several regions of quinoa cultivation. Silicon (Si) can attenuate the stress caused by nutritional deficiency, but studies on the effects of Si supply on quinoa plants are still scarce. Given this scenario, our objective was to evaluate the symptoms in terms of tissue, physiological and nutritional effects of quinoa plants submitted to nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) deficiencies under Si presence. The experiment consisted of a factorial scheme 6 × 2, using a complete solution (CS), -N, -P, -K, -Ca, -Mg combined with absence and presence of Si (1.5 mmol L-1). Symptomatic, physiological, nutritional and evaluation vegetative were performed in quinoa crop. The deficiencies of N, P, K, Ca and Mg in quinoa cultivation caused visual symptoms characteristic of the deficiency caused by respective nutrients, hence decreasing the plant dry mass. However, Si supply attenuated the deficiency effects by preserving the photosynthetic apparatus, increasing the chlorophyll production, increasing the membrane integrity, and decreasing the electrolyte leakage. Thus, the Si supply attenuated the visual effects provided by deficiency of all nutrients, but stood out for N and Ca, because it reflected in a higher dry mass production. This occurred because, the Si promoted higher synthesis and protection of chlorophylls, and lower electrolyte leakage under Ca restriction, as well as decreased electrolyte leakage under N restriction.

Knowledge of Oral Cancer by a Brazilian Population.

The aim of the present study was to investigate the knowledge about oral cancer in a Brazilian population, including initial clinical signs, causal factors, and the health professional of first choice when suspected of the disease. A total of 2261 participants were interviewed in a cross-sectional study, to investigate associations between sociodemographic descriptive variables and knowledge of oral cancer, risk factors, disease precursor lesions, and health professional of choice for diagnosis. The variables were descriptively analyzed and possible associations investigated considering p values < 0.05. A total of 83.4% of participants reported knowing about oral cancer, and 59.5% reported knowing about potentially malignant lesions; both variables were associated (p < 0.0001). Tobacco was identified as the main risk factor (83.6%), followed by family history (66.2%), and poor oral hygiene (54.5%). Interviewees with higher education level had greater knowledge about cancer (p < 0.0001), and the dentist was the health professional of choice for 43.1% of those who knew about the disease (p = 0.007), with the generalist being the most sought specialist. The population evaluated had a low knowledge of oral cancer given the lack of specific clarifications on etiological factors and risk situations. Health education initiatives are necessary to increase population awareness of potentially malignant oral lesions and improve early diagnosis and recognition of the dentist as a qualified professional for diagnosis of the disease.

Cuidado em saúde das mulheres grávidas privadas de liberdade: revisão integrativa / Atención médica para las mujeres embarazadas privadas de libertad: revisión integradora / Health care of pregnant women deprived of their liberty: integrative review

Objetivo analisar as publicações nacionais e internacionais acerca da assistência ao pré-natal oferecida às mulheres privadas de liberdade. Método revisão integrativa da literatura. As buscas foram realizadas em bases de dados, usando descritores e palavras-chave separadas por operadores boleanos. A busca resultou em 548 estudos. Após análise dos critérios de inclusão e exclusão com leitura analítica, foram selecionados 11 estudos primários, que foram organizados nas categorias estudos nacionais e internacionais. Resultados são necessárias adequações e melhorias na assistência à saúde dessas mulheres que, mesmo tendo direitos vigentes, sofrem negligência na assistência oferecida. Conclusão a vivência do pré-natal no cárcere está repleta de dificuldades e peculiaridades a depender da penitenciária, exigindo dos gestores e dos profissionais de saúde um olhar atento às necessidades da mulher, da criança e de seus familiares, na tentativa de minimizar os impactos do contexto prisional na qualidade de vida das pessoas envolvidas.

Objetivo analizar las publicaciones nacionales e internacionales sobre la atención prenatal ofrecida a las mujeres privadas de libertad. Método revisión integradora de la literatura. Las búsquedas se realizaron en bases de datos, utilizando descriptores y palabras clave separadas por operadores boleanos. La búsqueda dio como resultado 548 estudios. Tras analizar los criterios de inclusión y exclusión con lectura analítica, se seleccionaron 11 estudios primarios, que se organizaron en las categorías de estudios nacionales e internacionales. Resultados se necesitan ajustes y mejoras en el cuidado de la salud de estas mujeres que, a pesar de tener derechos existentes, son negligentes en el cuidado ofrecido. Conclusión la experiencia prenatal en la cárcel está llena de dificultades y peculiaridades según el centro penitenciario, lo que exige que los gestores y los profesionales de la salud examinen detenidamente las necesidades de las mujeres, los niños y sus familias, en un intento por reducir al mínimo los efectos del contexto carcelario en la calidad de vida de las personas implicadas.

Objective to analyze national and international publications on prenatal care offered to women deprived of their liberty. Method integrative literature review. Searches were conducted in databases, using descriptors and keywords separated by Boolean operators. Tthe search resulted in 548 studies. After analysis of inclusion and exclusion criteria with analytical reading, 11 primary studies were selected, which were organized in the categories national and international studies. Results adjustments and improvements in health care are needed for these women who, even though they have existing rights, are negligent in the care offered. Conclusion the prenatal experience in prison is full of difficulties and peculiarities depending on the penitentiary, requiring managers and health professionals an attentive look at the needs of women, children and their family members, in an attempt to minimize the impacts of the prison context on the quality of life of the people involved.
