Perfil de ácidos graxos no Longissimus dorsi de cordeiros Santa Inês alimentados com diferentes níveis energéticos.

Resumo: O presente estudo objetivou avaliar a influência de rações com diferentes níveis de energia metabolizável sobre o teor de lipídeos totais, colesterol e perfil de ácidos graxos no músculo Longissimus dorsi de cordeiros Santa Inês. Foram utilizados 20 cordeiros, com idade e peso de 50 dias e 13,0 ± 0,56 kg, respectivamente, alimentados com rações contendo diferentes níveis energéticos: 2,08; 2,28; 2,47 e 2,69 Mcal/kgMS. Os animais foram pesados semanalmente para acompanhamento do ganho de peso vivo, quando a média do peso vivo do tratamento atingiu 28 kg, os animais foram abatidos. A análise do perfil lipídico do músculo Longissimus dorsi apresentou efeito linear crescente e decrescente para os ácidos Cis-10 heptadecanóico (C17:1) e eicosatrienóico (C20:3), respectivamente, com o aumento nos níveis de energia dietéticos (P0,05). A manipulação dietética influencia o perfil lipídico no Longissimus dorsi de cordeiros Santa Inês. [Fatty acids profile in Longissimus dorsi of Santa Ines lambs fed with different energy levels]. Abstract: This study evaluated the influence of rations with different levels of metabolizable energy on the content of total lipids, cholesterol and fatty acid profile of the longissimus dorsi of Santa Ines lambs. Twenty Santa Ines lambs were used, with age and body weight of 50 days and 13.0 ± 0.56 kg, respectively, fed rations with different energy levels: 2.08; 2.28; 2.47 e 2.69 Mcal/kgDM. Animals were weighed weekly to follow their body weight gain (BWG); when the mean BW of the treatment reached 28 kg, the animals were slaughtered. The analysis of the lipid profile of Longissimus dorsi presented linear increasing and decreasing for the Cis-10 heptadecanoic acid (C17:1) and eicosatrienoic (C20:3), respectively, with the increasing dietary energy levels (P 0.05). The dietary manipulation influences the lipid profile in Longissimus dorsi of Santa Ines lambs

Determinação das frações proteicas e de carboidratos e estimativa do valor energético de forrageiras e subprodutos da agroindústria produzidos no Nordeste Brasileiro.

O presente estudo objetivou caracterizar as frações de carboidratos e proteína, e estimar o valor energético de forrageiras nativas e adaptadas, e de subprodutos da agroindústria produzidos na região Nordeste do Brasil. Para obtenção do fracionamento dos carboidratos, de acordo com o sistema CNCPS, foram calculados os carboidratos totais, suas frações B2, C e os componentes solúveis em detergente neutro. Para determinação das frações nitrogenadas, foram analisados os compostos nitrogenados não- proteicos, nitrogênio solúvel e insolúvel em tampão borato-fosfato e nitrogênio protéico insolúvel em detergente neutro e em detergente ácido. Para estimativa do NDT foram utilizadas as equações propostas pelo NRC (2001). As frações de carboidratos dos subprodutos analisados variaram de 19,35 a 58,52%; 9,95 a 61,44% e 15,35 a 70,06% para A+B1, B2 e C, respectivamente. Nas forrageiras, as frações A, B1, B2, B3 e C dos compostos nitrogenados apresentaram variação de 9,84 a 42,33%; 1,58 a 11,47%; 48,63 a 80,10%; 0,70 a 6,13% e 0,43 a 2,86%, respectivamente. O NDT estimado das forrageiras variou de 48,30 a 65,42%, enquanto para os subprodutos variou de 31,41 a 128,90%. O fracionamento dos compostos nitrogenados e de carboidratos são metodologias simples e devem ser usuais em laboratórios de avaliação de alimentos

Measuring Adherence to Inhaled Control Medication in Patients with Asthma: Comparison Among an Asthma App, Patient Self‐Report and Physician Assessment

Background: Previous studies have demonstrated the feasibility of using an asthma app to support medication management and adherence but failed to compare with other measures currently used in clinical practice. However, in a clinical setting, any additional adherence measurement must be evaluated in the context of both the patient and physician perspectives so that it can also help improve the process of shared decision making. Thus, we aimed to compare different measures of adherence to asthma control inhalers in clinical practice, namely through an app, patient self-report and physician assessment. Methods: This study is a secondary analysis of three prospective multicentre observational studies with patients (≥13 years old) with persistent asthma recruited from 61 primary and secondary care centres in Portugal. Patients were invited to use the InspirerMundi app and register their inhaled medication. Adherence was measured by the app as the number of doses taken divided by the number of doses scheduled each day and two time points were considered for analysis: 1-week and 1-month. At baseline, patients and physicians independently assessed adherence to asthma control inhalers during the previous week using a Visual Analogue Scale (VAS 0-100). Results: A total of 193 patients (72% female; median [P25-P75] age 28 [19-41] years old) were included in the analysis. Adherence measured by the app was lower (1 week: 31 [0-71]%; 1 month: 18 [0-48]%) than patient self-report (80 [60-95]) and physician assessment (82 [51-94]) (p 0.05). There was a moderate correlation between patient self-report and physician assessment (ρ = 0.596, p < 0.001). Conclusions: Adherence measured by the app was lower than that reported by the patient or the physician. This was expected as objective measurements are commonly lower than subjective evaluations, which tend to overestimate adherence. Nevertheless, the low adherence measured by the app may also be influenced by the use of the app itself and this needs to be considered in future studies.info:eu-repo/semantics/publishedVersio

"Dreaming in colour’: disabled higher education students’ perspectives on improving design practices that would enable them to benefit from their use of technologies"

The focus of this paper is the design of technology products and services for disabled students in higher education. It analyses the perspectives of disabled students studying in the US, the UK, Germany, Israel and Canada, regarding their experiences of using technologies to support their learning. The students shared how the functionality of the technologies supported them to study and enabled them to achieve their academic potential. Despite these positive outcomes, the students also reported difficulties associated with: i) the design of the technologies, ii) a lack of technology know-how and iii) a lack of social capital. When identifying potential solutions to these difficulties the disabled students imagined both preferable and possible futures where faculty, higher education institutions, researchers and technology companies are challenged to push the boundaries of their current design practices
