RESUMO

Cassava is an important staple food for low-income countries. However, its cooking characteristics are especially affected by genotype. In this study, two groups of genotypes, namely hard to cook (HTC) and easy to cook (ETC), were harvested at different times (9 and 15 months), and evaluated by NMR coupled to chemometrics. Additionally, lignin of these materials was studied by 1H-13C HSQC NMR. The carbohydrates were the most important class of compounds to differentiate the cassava genotypes. The correlation of NMR with cooking time and starch content showed that the higher content of primary metabolites, mostly glucose, can be associated with longer cooking times and reduction of starch, corroborating the metabolic pathways analysis. Furthermore, it was observed that the lignin from cell walls did not differentiate the cooking performance of the genotypes.

RESUMO

OBJECTIVE: To identify the skin temperature in different body areas of hospitalised individuals in the surgical unit, without risk of developing a pressure ulcer (PU). METHODS: A descriptive, correlational and cross-sectional study, carried out May-October 2017, in a surgical unit of a university hospital in southern Brazil. Temperature was measured at the bony prominences including scapula, elbow, trochanters and heels, on both sides of the body, as well as occipital and sacral regions. RESULTS: A total of 230 patients took part in the study. All regions of the body measured presented differences in temperatures. The sacral region presented the highest mean temperature (34.2±0.1°C). Patients (aged 18-59 years) had higher skin temperatures in the sacral region than older patients (aged 60-88 years). There was a symmetry in temperatures on both sides of the body. There was a low degree of correlation between age, room temperature, room humidity and skin temperature in some body regions. CONCLUSION: The study established mean values for skin temperature in specific body regions in patients without risk of developing a PU, hospitalised in a surgical unit. It also demonstrates how skin temperature can be used as a clinical parameter in practice to support the prevention of PUs.

RESUMO

OBJECTIVE: To evaluate quality of life in elderly patients with obstructive sleep apnea (OSA) who have a pacemaker. METHODS: This was a cross-sectional study involving elderly patients (≥ 60 years of age) with a pacemaker. The dependent variable was quality of life, as evaluated with the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). Sociodemographic and clinical parameters, including anxiety and depression (Hospital Anxiety and Depression Scale score), as well as the presence of OSA (defined as an apnea-hypopnea index ≥ 15 events/h), were analyzed as independent variables. Patients with cognitive/neurological deficits or decompensated heart failure were excluded. RESULTS: We evaluated 72 patients, 17 (23.6%) of whom presented OSA. Of those 17 patients, 9 (52.9%) were male. The mean age was 72.3 ± 9.3 years. A diagnosis of OSA was not associated with gender (p = 0.132), age (p = 0.294), or body mass index (p = 0.790). There were no differences between the patients with OSA and those without, in terms of the SF-36 domain scores. Fourteen patients (19.4%) presented moderate or severe anxiety. Of those 14 patients, only 3 (21.4%) had OSA (p = 0.89 vs. no OSA). Twelve patients (16.6%) had moderate or severe depression. Of those 12 patients, only 2 (16.6%) had OSA (p = 0.73 vs. no OSA). CONCLUSIONS: In elderly patients with a pacemaker, OSA was not found to be associated with quality of life or with symptoms of anxiety or depression.

RESUMO Objetivo: Avaliar a qualidade de vida em idosos portadores de marca-passo e apneia obstrutiva do sono (AOS). Métodos: Estudo de corte transversal com idosos (idade ≥ 60 anos) portadores de marca-passo cardíaco. A variável dependente foi qualidade de vida, avaliada por meio do Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). Dados sociodemográficos e clínicos foram analisados como variáveis independentes, entre os quais ansiedade e depressão (por meio da Hospital Anxiety and Depression Scale), assim como presença de AOS (definida como um índice de apneia-hipopneia ≥ 15 eventos/h). Pacientes com déficits cognitivos/neurológicos ou descompensação cardíaca foram excluídos. Resultados: A amostra foi composta por 72 pacientes, 17 dos quais (23,6%) apresentaram AOS - 9 homens (52,9%). A média de idade foi de 72,3 ± 9,3 anos. Não houve associações de presença de AOS com sexo (p = 0,132), idade (p = 0,294) e índice de massa corpórea (p = 0,790). Não foram observadas diferenças dos domínios do SF-36 entre os grupos com e sem AOS. Em relação à ansiedade, 14 pacientes (19,4%) apresentaram sintomas moderados ou graves, dos quais apenas 3 (21,4%) tinham AOS (p = 0,89 vs. sem AOS). No tocante à depressão, 12 pacientes (16,6%) apresentaram sintomas moderados ou graves, dos quais 2 (16,6%) tinham AOS (p = 0,73 vs. sem AOS). Conclusões: Nesta amostra em idosos portadores de marca-passo, a presença de AOS não foi associada a qualidade de vida e sintomas de ansiedade e depressão.
