La música en el desarrollo de la espiritualidad y la religiosidad. Una aproximación al Cristianismo y al Budismo

La música puede afectar al individuo en todos sus niveles –físico, mental y espiritual–. El presente artículo se centra en el papel que ésta desempeña en el desarrollo de la vida espiritual y trascendental. Para ello, realizaremos un repaso histórico de su evolución estética y social, abordaremos dicho fenómeno a nivel fisiológico y presentaremos sus aplicaciones clínicas y sociales. Seguidamente y a modo de ejemplo de las concepciones de pensamiento occidental y oriental, trataremos la forma en que el cristianismo y el budismo conciben la música dentro de su doctrina. Finalizaremos con algunas reflexiones sobre el tema.

Beyond the numbers of maternal near-miss in Rwanda - a qualitative study on women's perspectives on access and experiences of care in early and late stage of pregnancy.

BACKGROUND: Rwanda has made remarkable progress in decreasing the number of maternal deaths, yet women still face morbidities and mortalities during pregnancy. We explored care-seeking and experiences of maternity care among women who suffered a near-miss event during either the early or late stage of pregnancy, and identified potential health system limitations or barriers to maternal survival in this setting. METHODS: A framework of Naturalistic Inquiry guided the study design and analysis, and the 'three delays' model facilitated data sorting. Participants included 47 women, who were interviewed at three hospitals in Kigali, and 14 of these were revisited in their homes, from March 2013 to April 2014. RESULTS: The women confronted various care-seeking barriers depending on whether the pregnancy was wanted, the gestational age, insurance coverage, and marital status. Poor communication between the women and healthcare providers seemed to result in inadequate or inappropriate treatment, leading some to seek either traditional medicine or care repeatedly at biomedical facilities. CONCLUSION: Improved service provision routines, information, and amendments to the insurance system are suggested to enhance prompt care-seeking. Additionally, we strongly recommend a health system that considers the needs of all pregnant women, especially those facing unintended pregnancies or complications in the early stages of pregnancy.

Exercise and Lifestyle Therapy Improves Weight Maintenance in Young People With Psychosis: A Service Evaluation

INTRODUCTION Young people with psychosis typically have higher rates of premature cardiovascular disease and metabolic disorders compared to non-psychotic peers. This has been primarily due to a sedentary lifestyle, poor diet composition, misuse of harmful substances and higher rates of obesity and smoking. When prescribed obesogenic antipsychotic medication, a weight gain of >12 kg within 2 years is typical. PURPOSE: To examine the benefits of a 12 wk exercise and lifestyle intervention entitled ‘Supporting Health and Promoting Exercise’ (SHAPE) for young people recently diagnosed with psychosis. METHODS Participants (n=26; 8 females; mean age 27.7 ± 5.1) engaged in weekly 45’ education sessions on healthy lifestyle behaviors, including: managing anxiety and depression, mindfulness and relaxation training, substance misuse, smoking cessation, healthy eating and nutritional advice, dental and sexual health care. This was followed by a 45’ exercise session including activities such as circuit and resistance training, yoga, and badminton, led by qualified exercise instructors. Anthropometric data were measured at baseline, 12 wk and 12 month post-intervention. Lifestyle behaviors and clinical measurements, including resting heart rate, blood pressure, total cholesterol, triglycerides, HbA1c and prolactin, were assessed at baseline and 12 months post-intervention as part of their routine clinical care plan. Significant differences over time were assessed using Paired Sample t-tests. RESULTS SHAPE participants (n=26) presented with first episode psychosis (n=11), schizophrenia (n=11), bipolar disorder (n=2), at risk mental state (n=1), and persistent delusion disorder (n=1) of which 52% were prescribed highly obesogenic antipsychotic medications (Clozapine and Olanzepine). Mean baseline data suggests participants were at an increased health risk due to elevated values in mean BMI (70% were overweight or obese), waist circumference, resting heart rate, and triglycerides (see Table 1 & 2). Over 50% reported smoking daily and 85% had elevated resting blood pressure (>120/80 mm Hg). At 12 wk post-intervention, no changes were observed in mean BMI or waist circumference (see Table 1); 19 participants either maintained (mean 0.5 kg: range ± 2 kg) or decreased (mean -5.7 kg: range 2-7 kg) weight; 7 participants increased weight (mean 4.9 kg: range 2.0-9.6 kg). At 12 month post-intervention (n=16), no change was evident in mean BMI, waist circumference, or any other clinical variable (see Table 2). Positive impacts on lifestyle behaviors included 7 participants eating ~400g of fruit/vegetables daily, 2 ceased substance use, 2 ceased alcohol use, 4 ceased smoking and 5 were less sedentary. CONCLUSION At the start of the programme, participants were already at an increased risk for cardiometabolic disorders. Findings suggest that SHAPE supported young people with psychosis to: -attenuate their physical health risk following a 12 wk exercise and lifestyle intervention which were sustained at 12 months follow up. -make positive lifestyle behavior changes leading to sustained improvements in weight maintenance and physical health.

E-cigarette puffing patterns associated with high and low nicotine e-liquid strength: effects on toxicant and carcinogen exposure

Contrary to intuition, use of lower strength nicotine e-liquids might not offer reduced health risk if compensatory puffing behaviour occurs. Compensatory puffing (e.g. more frequent, longer puffs) or user behaviour (increasing the wattage) can lead to higher temperatures at which glycerine and propylene glycol (solvents used in e-liquids) undergo decomposition to carbonyl compounds, including the carcinogens formaldehyde and acetaldehyde. This study aims to document puffing patterns and user behaviour associated with using high and low strength nicotine e-liquid and associated toxicant/carcinogen exposure in experienced e-cigarette users (known as vapers herein).

Use of time-resolved spectroscopy as a method to monitor carotenoids present in tomato extract obtained using ultrasound treatment

Introduction Compounds exhibiting antioxidant activity have received much interest in the food industry because of their potential health benefits. Carotenoids such as lycopene, which in the human diet mainly derives from tomatoes (Solanum lycopersicum), have attracted much attention in this aspect and the study of their extraction, processing and storage procedures is of importance. Optical techniques potentially offer advantageous non-invasive and specific methods to monitor them. Objectives To obtain both fluorescence and Raman information to ascertain if ultrasound assisted extraction from tomato pulp has a detrimental effect on lycopene. Method Use of time-resolved fluorescence spectroscopy to monitor carotenoids in a hexane extract obtained from tomato pulp with application of ultrasound treatment (583 kHz). The resultant spectra were a combination of scattering and fluorescence. Because of their different timescales, decay associated spectra could be used to separate fluorescence and Raman information. This simultaneous acquisition of two complementary techniques was coupled with a very high time-resolution fluorescence lifetime measurement of the lycopene. Results Spectroscopic data showed the presence of phytofluene and chlorophyll in addition to lycopene in the tomato extract. The time-resolved spectral measurement containing both fluorescence and Raman data, coupled with high resolution time-resolved measurements, where a lifetime of ~5 ps was attributed to lycopene, indicated lycopene appeared unaltered by ultrasound treatment. Detrimental changes were, however, observed in both chlorophyll and phytofluene contributions. Conclusion Extracted lycopene appeared unaffected by ultrasound treatment, while other constituents (chlorophyll and phytofluene) were degraded.

Processos degenerativos do tecido cutâneo

Os processos degenerativos do tecido cutâneo estão amplamente associados ao seu envelhecimento natural, onde se verifica perda de tecido fibroso, renovação celular mais lenta e redução da rede vascular e glandular da pele. Alguns fatores externos ao organismo podem contudo acelerar estes processos, como por exemplo a exposição solar, consumo excessivo de álcool e tabaco, poluição ambiental e aumento de peso. De entre estes processos destacam-se o processo descamativo, um fenómeno natural do mecanismo de diferenciação dos queratinócitos. É um processo complexo que envolve essencialmente a degradação da coesão entre células da pele. A lipodistrofia ginóide é outro destes processos, comummente denominado de celulite, e que se caracteriza como uma distrofia celular complexa, com alterações do metabolismo hídrico que conferem uma aparência de "casca de laranja" à pele. A flacidez é um processo resultante da atrofia tecidular, onde se verifica a perda progressiva de massa muscular que é substituída por tecido adiposo. Está diretamente relacionada com a redução da produção de fibras de colagénio e fibras elásticas no tecido subcutâneo. Por fim, insuficiência venosa é um termo utilizado para caracterizar um processo que afeta o sistema venoso dos membros inferiores, que se desenvolve por aumento da pressão venosa em combinação com um retorno venoso ineficiente. Embora ainda não exista compreensão total destes mecanismos, já é possível encontrar uma série de tratamentos que visam minimizar ou mesmo tratá-los, de modo a que não se agravem e representem um risco sério para a saúde.

Hazelnut Allergens: Molecular Characterisation, Detection and Clinical Relevance

In the last years, special attention has been devoted to food-induced allergies, from which hazelnut allergy is highlighted. Hazelnut is one of the most commonly consumed tree nuts, being largely used by the food industry in a wide variety of processed foods. It has been regarded as a food with potential health benefits, but also as a source of allergens capable of inducing mild to severe allergic reactions in sensitised individuals. Considering the great number of reports addressing hazelnut allergens, with an estimated increasing trend, this review intends to assemble all the relevant information available so far on the main issues: prevalence of tree nut allergy, clinical threshold levels, molecular characterisation of hazelnut allergens (Cor a 1, Cor a 2, Cor a 8, Cor a 9, Cor a 10, Cor a 11, Cor a 12, Cor a 14 and Cor a TLP) and their clinical relevance, and methodologies for hazelnut allergen detection in foods. A comprehensive overview on the current data about the molecular characterisation of hazelnut allergens is presented, relating biochemical classification and biological function with clinical importance. Recent advances on hazelnut allergen detection methodologies are summarised and compared, including all the novel protein- and DNA-based approaches.

Innovating a consumer awareness of sweetpotato: industry, research and consumer adoption issues

In Australia, sweetpotato production has grown remarkably (1700%) in the last 16 years. Growers currently market 75 000 t per annum, worth $80-90 million at farm gate. The orange-fleshed cultivars are the most familiar to consumers, but other cultivars with varying flesh colour and properties also have potential for the consumer market. Given that Australian sweetpotato growers desire alternative cultivars to promote market demand, it is important to articulate the characteristics of sweetpotatoes that are most and least desirable for consumers. Research indicates that consumer acceptability of the new cultivar 'Evangeline' may assist sweetpotato growers and marketers in understanding the impact of both sensory properties, such as colour and the importance of flavour and texture of sweetpotatoes, and an awareness of the potential health benefits of sweetpotato consumption. In addition, whilst consumer preferences (regarding size, colour, texture, skin tone) and nutritional knowledge of sweet potato (regarding glycaemic index) is increasing, there is limited research investigating consumers understanding of health messages of sweetpotato attributes. This industry and consumer research review highlights the potential for promoting innovative strategies to improve adoption of new cultivars in the marketplace.

The impact of cooking methods on the nutritional quality and safety of chicken breaded nuggets

The impact of cooking methods (industrial pre-frying, deep-fat frying and baking) on the nutritional quality and safety of chicken breaded nugget samples from supermarket and commercial brands was evaluated. The changes in the quality characteristics (nutritional composition, fatty acids profile, cholesterol and salt) of the fried food and frying oil, after ten consecutive frying operations, were evaluated. The total fat content of nuggets varied between 10.9 and 22.7 g per 100 g of edible portion and the salt content ranged from 0.873 to 1.63 g per 100 g. Taking into account one portion of nuggets, the daily intake of salt can reach 49%, which can have a significant impact on the health of those who regularly consume this type of food, especially considering the prevalence of hypertension around the world. The analysed chicken breaded nuggets are rich in unsaturated fatty acids, which have been related with potential health benefits, namely regarding cardiovascular diseases. The cholesterol content of baked samples was two times higher when compared with the fried ones. The trans fatty acids and polar compounds contents of the frying oil used for frying significantly increased, but the values were still away from the maximum recommended by legal entities for its rejection. From a nutritional point of view, it is possible to conclude that the applied cooking methods can significantly influence the nutritional quality and safety of the analysed chicken breaded nuggets. This study will contribute to important knowledge on how the applied cooking methods can change the nutritional quality and safety of foods, namely of chicken nuggets, and can be very useful for dietary recommendations and nutritional assessment.

Estudo das propriedades físico-químicas e avaliação de compostos bioativos em camarinhas ('Corema album' L.D. Don)

As camarinhas ('Corema album' L. D. Don) são pequenos frutos selvagens que se desenvolvem em arbustos dunares ao longo das costas da Península Ibérica. Apesar de serem ainda pouco conhecidas, as camarinhas são pequenos frutos que podem pertencer ao vasto grupo dos frutos vermelhos, vulgarmente conhecidos pelos seus efeitos benéficos na saúde. Desta forma, neste estudo foram realizadas várias análises às camarinhas no que respeita a propriedades de natureza física e química e em particular a alguns compostos com efeitos bioativos. Com a realização deste trabalho pretendeu-se avaliar as propriedades físico-químicas das camarinhas, bem como dos compostos bioativos com potenciais benefícios para a saúde. Nesse sentido, as bagas de camarinha foram avaliadas quanto às suas propriedades físicas (dimensões, peso, cor e textura), propriedades químicas (humidade, acidez, ºBrix, fibra, açúcares totais, açúcares redutores e vitamina C) e propriedades fenólicas (compostos fenólicos totais, orto-difenóis, flavonóides, taninos e atividade antioxidante, por DPPH e ABTS), em diferentes extratos de amostras de polpas e de grainhas liofilizadas. Os primeiros extratos ainda foram submetidos a uma simulações das condições do trato digestivo, para avaliar a bioacessibilidade dos compostos fenólicos e da atividade antioxidante. Este trabalho teve ainda como objetivo conhecer a bioacessibilidade dos compostos fenólicos totais e da sua atividade antioxidante, através do método da simulação “in vitro” das diferentes etapas do trato gastrointestinal. No que diz respeito às propriedades físicas analisadas, as camarinhas frescas demonstraram uma altura média de 8,6 mm, um diâmetro médio de 9,4 mm e uma massa média de 0,7 g. Relativamente à caraterização da cor, estas apresentavam uma cor clara (L*=79,8). Quanto à textura apresentaram alguma elasticidade média (2,9 mm) e uma baixa dureza (1,9 N). Nas análises químicas as camarinhas revelaram ser compostas, maioritariamente, por água (87,9%), por açúcares totais e fibras. Para além disso, apresentavam um teor em sólidos solúveis totais de 6,3 ºBrix, uma acidez de 1,4 g ácido tartárico/100 g e um teor de vitamina C de 2,8 mg de ácido ascórbico/100 g.Na quantificação dos compostos fenólicos totais e flavonóides, os extratos de acetona:água das amostras de polpas de camarinha branca apresentaram os valores mais elevados, 1614,1 mg EAG/100 g e 143,7 mg EQ/100 g, respetivamente. Relativamente à quantificação dos orto-difenóis e dos taninos os extratos de metanol e de acetona:água das amostras de grainhas de camarinha branca registaram os valores de 23,4 mg EAG/100 g e 915,7 mg/100 g, respetivamente. Na atividade antioxidante por DPPH e ABTS os extratos de acetona:água das amostras de polpas de camarinha branca apresentaram, respetivamente, os valores de 40,1 µmol ET/g e de 79,6 µmol ET/g. Na avaliação da bioacessibilidade verificou-se que ocorreu uma maior percentagem de compostos fenólicos disponíveis para absorção e uma maior preservação da sua atividade antioxidante nos extratos das grainhas, comparativamente aos extratos das polpas. Com este estudo concluiu-se que as camarinhas são pequenos frutos portadores de um grande potencial em diversos compostos bioativos benéficos para a saúde dos consumidores.

Children exposure to indoor ultrafine particles in urban and rural school environments

Extended exposure to ultrafine particles (UFPs) may lead to consequences in children due to their increased susceptibility when compared to older individuals. Since children spend in average 8 h/day in primary schools, assessing the number concentrations of UFPs in these institutions is important in order to evaluate the health risk for children in primary schools caused by indoor air pollution. Thus, the purpose of this study was to assess and determine the sources of indoor UFP number concentrations in urban and rural Portuguese primary schools. Indoor and outdoor ultrafine particle (UFP) number concentrations were measured in six urban schools (US) and two rural schools (RS) located in the north of Portugal, during the heating season. The mean number concentrations of indoor UFPs were significantly higher in urban schools than in rural ones (10.4 × 10(3) and 5.7 × 10(3) pt/cm(3), respectively). Higher UFP levels were associated with higher squared meters per student, floor levels closer to the ground, chalk boards, furniture or floor covering materials made of wood and windows with double-glazing. Indoor number concentrations of ultrafine-particles were inversely correlated with indoor CO2 levels. In the present work, indoor and outdoor concentrations of UFPs in public primary schools located in urban and rural areas were assessed, and the main sources were identified for each environment. The results not only showed that UFP pollution is present in augmented concentrations in US when compared to RS but also revealed some classroom/school characteristics that influence the concentrations of UFPs in primary schools.

Comunicação de risco em saúde : a importância do eWOM

Os surtos de doenças infeciosas estão atualmente no topo das preocupações relacionadas com riscos de saúde, devido à grande capacidade de disseminação e difusão que as caracteriza e, não menos importante, por causa da eventual possibilidade de evolução dos surtos para o nível de pandemia. A nível global, os Governos e as organizações oficiais de saúde estão empenhados em criar planos para lidar com os riscos de saúde, de forma a mitigar e controlar os efeitos nefastos provocados pelas doenças infeciosas na população. O mundo mudou, devido às novas tecnologias, tornou-se globalmente digital. As pessoas, hoje, têm um novo estatuto, são atores sociais, unidos por laços sociais no seio das redes digitais, dentro das quais, têm acesso a uma vasta panóplia de informação - acerca de assuntos de saúde por exemplo, que flui livremente através da rede e diminui os limites entre o cidadão comum e os profissionais e os peritos acerca dos mais diversos temas. O utilizador atual de internet, é um "prosumer". A tecnologia permite-lhe pesquisar a informação que procura e, adicionalmente, compartilhar e comentar o resultado das suas pesquisas e da sua própria experiência pessoal. No contexto dos riscos de saúde, a comunicação é um elemento preponderante em qualquer estratégia de planeamento de risco. Por sua vez, a internet, os novos media digitais e as redes sociais online, são ferramentas postas à disposição dos consumidores, que lhes possibilitam a procura a partilha e o armazenamento de informação. Em virtude da importância que assume a comunicação nos cenários de crise, no âmbito deste trabalho, centraremos o foco da nossa atenção, nos fenómenos de comunicação, conhecidos por “passa-palavra” e “passa-palavra eletrónico” (WOM e WOM), revelando a sua influência na participação dos consumidores na dinâmica comportamental de partilha de eWOM, dentro do grupo restrito de cada indivíduo (eWOM dentro do grupo). Para produzir o nosso modelo concetual, usaram-se medidas adaptadas de outros construtos retirados da literatura, nomeadamente, “Credibilidade da fonte”; “Credibilidade de informação” e “eWOM Dentro do Grupo”.

Prevalence and characterization of Salmonella spp. in three shellfish-harvesting areas in France

Shellfish farming is an important economic activity in the Brittany and Normandy regions. However, a part of the production sites corresponds to relatively sensitive areas where the presence of faecal microorganisms is a major concern for shellfish and constitutes a possible health risk. Indeed, shellfish bioaccumulates in their tissues pathogenic contaminants present in water and can cause food-borne diseases such as salmonellosis. During a two-year study, we evaluated the presence of faecal indicators, measured the prevalence of Salmonella spp., isolated and characterized Salmonella spp. from three French shellfish-harvesting areas (shellfish and sediment) and their watersheds (from river water samples).

Examination of Faecal Caliform Presence in Groundwater in Ghana (A Case Study in Ketu South Municipality)

Samples were taken from wide-dam, open wells and compared with piped city water. Well water from both districts showed widespread contamination with faecal bacteria. This study revealed high Faecal and Total coliforms in all the samples with varying numbers. The high coliforms content of the eight hand-dug wells poses a health risk and renders the water unsuitable for human consumption. The presence of pathogenic organisms in the water could be attributed to pit latrine in the vicinity that extent their influence on these water qualities, since they are sited close to them.

Mapeamento de áreas de risco à saúde pública por meio de métodos geoestatísticos

Este trabalho tem por objetivo apresentar uma aplicação de métodos geoestatísticos na elaboração de mapas de risco à saúde pública, por meio da identificação de áreas com maior concentração de metais pesados. Foi escolhido o elemento chumbo (Pb), resultante do transporte aéreo ou do carregamento das partículas causado pela lixiviação do solo, em uma região com grande concentração urbana e industrial na Baixada Santista, São Paulo, Brasil. Elaboraram-se mapas das distribuições espaciais desse elemento por intermédio da krigagem ordinária; posteriormente, utilizando-se a krigagem indicativa, identificaram-se as áreas com valores de contaminação do solo superiores aos níveis máximos aceitáveis pelo órgão de controle ambiental do Estado de São Paulo, originando um mapeamento com áreas com maior probabilidade de risco à saúde pública. Os mapas resultantes mostraram-se ferramentas promissoras para auxiliar a tomada de decisão quanto a questões de políticas públicas relacionadas à saúde e ao planejamento ambiental.
