The Role of Sarcopenic Obesity in Cancer and Cardiovascular Disease: A Synthesis of the Evidence on Pathophysiological Aspects and Clinical Implications

Obesity is globally a serious public health concern and is associated with a high risk of cardiovascular disease (CVD) and various types of cancers. It is important to evaluate various types of obesity, such as visceral and sarcopenic obesity. The evidence on the associated risk of CVD, cancer and sarcopenic obesity, including pathophysiological aspects, occurrence, clinical implications and survival, needs further investigation. Sarcopenic obesity is a relatively new term. It is a clinical condition that primarily affects older adults. There are several endocrine-hormonal, metabolic and lifestyle aspects involved in the occurrence of sarcopenic obesity that affect pathophysiological aspects that, in turn, contribute to CVD and neoplasms. However, there is no available evidence on the role of sarcopenic obesity in the occurrence of CVD and cancer and its pathophysiological interplay. Therefore, this review aims to describe the pathophysiological aspects and the clinical and epidemiological evidence on the role of sarcopenic obesity related to the occurrence and mortality risk of various types of cancer and cardiovascular disease. This literature review highlights the need for further research on sarcopenic obesity to demonstrate the interrelation of these various associations

Multivariate analysis reveals genetic diversity in Paspalum notatum Flügge

The objective of this study was to evaluate 94 Paspalum notatum genotypes over two growing seasons to estimate genetic dissimilarity through agronomic traits and the distance between genotypes. This information is used to create an ideotype from the best averages obtained for the set of characteristics evaluated. Seven apomitic, three sexual, and 81 hybrid genotypes were compared with native genotypes “André da Rocha”, “Bagual”, and cultivar “Pensacola” as controls. There is genetic variability in P. notatum for the studied characteristics, and distinct genotypes with superior characteristics can be used in new combinations between apomictic and sexual plants to obtain hybrids. The characters with the greatest relative contribution to the dissimilarity between the genotypes were tiller density, stem dry mass, and leaf dry mass yield. Thus, these characteristics are suitable criteria to infer genetic distance studies in P. notatum. The selection index based on the ideotype is an auxiliary tool in the breeding process. The ideotype must be based on characteristics of interest according to the objective of the breeding program, as well as on the breeder’s prior knowledge in relation to culture

Genetic parameters, prediction of gains and intraspecific hybrid selection of Paspalum notatum Flügge for forage using REML/BLUP

Genetic improvement of native forage species is a sustainable alternative for maximizing livestock production. Paspalum notatum Flügge is the most important forage grass in the native grasslands of southern Brazil, with substantial potential available for further genetic improvement. The objective of this study was to quantify a range of genetic parameters and predict yield gains in a population of P. notatum intraspecific hybrids. Results indicated intraspecific hybrids of P. notatum had high magnitudes of heritability in the broad and average sense of genotype, plus high selective accuracy and genetic variation for all forage characteristics evaluated. This indicated REML/BLUP can contribute useful information for plant selection in future plant breeding programs. The genetic material studied showed high genetic variability for forage production. Analysis indicated hybrids 336, 332, 437, 132 and male parent '30N' should be included in new crosses to increase the dry matter production of P. notatum. Parents need to be selected from different groups in order to maximize genetic variability and heterosis. In addition, these parents must be included in diallel crosses. The results obtained in this study provide important information for the future breeding of improved P. notatum cultivars for commercialization

Promoção, prevenção e cuidado da hipertensão arterial no Brasil

OBJETIVO: Estimar a prevalência de ações de promoção, prevenção e cuidado da hipertensão arterial em adultos e identificar sua associação com estado descompensado de hipertensão. MÉTODOS: Estudo epidemiológico transversal de base populacional realizado por meio de entrevista com 12.324 adultos, de 20 a 59 anos, em 100 municípios brasileiros. As variáveis independentes, consideradas como promoção, prevenção e cuidado, foram: ter recebido orientações sobre a manutenção do peso ideal e sobre atividade física; ter consultado um médico e ter realizado eletrocardiograma no último ano. Pressão arterial acima de 140/90 mmHg foi considerada estado descompensado, sendo a variável dependente para a avaliação da qualidade do cuidado. RESULTADOS: Do total, 16,3% (n = 2.004) referiram diagnóstico médico de hipertensão. As maiores prevalências de hipertensão foram observadas na categoria de idade de 50 a 59 anos, concentradas nas regiões Sudeste e Centro-Oeste. Mais da metade (66,1%) esteve em consulta médica por hipertensão no último ano, da qual metade (52,4%) realizou eletrocardiograma. Dos hipertensos que tiveram sua pressão arterial aferida na entrevista (74,6%), menos da metade (42,4%) apresentava cifras tensionais descompensadas. CONCLUSÕES: Não houve associação entre haver consultado médico no último ano e cifras tensionais descompensadas. A proporção de hipertensos descompensados foi significativamente menor entre os que foram orientados para manter o peso ideal, realizar atividade física e os que fizeram eletrocardiograma. Ser do sexo masculino, ter idade acima de 40 anos e habitar na região Sul mostraram-se associados a estado descompensado da hipertensão.OBJECTIVE: To estimate the prevalence of promotion, prevention and arterial hypertension care actions in adults and to identify their association with decompensated hypertension. METHODS: A population-based cross-sectional epidemiological study was conducted by interviewing 12,324 adults aged from 20 to 59 years, in 100 Brazilian cities. The independent variables considered as promotion, prevention and hypertension care were as follows: to have received guidance on ideal weight maintenance and physical activity practice; to have consulted a doctor; and to have had an electrocardiogram performed in the previous year. A blood pressure higher than 140/90 mm/Hg was considered to be decompensated, being the dependent variable adopted to assess quality of care. RESULTS: Of all participants, 16.3% (n = 2,004) reported a medical diagnosis of hypertension. The highest prevalences of hypertension were observed in the 50 to 59 year age group, primarily in the Southeast and Center-West regions. More than half (66.1%) of participants had a medical consultation about hypertension in the previous year, of which half (52.4%) had an electrocardiogram. Of all those with hypertension who had their blood pressure measured during interview (74.6%), less than half (42.4%) had decompensated values. CONCLUSIONS: There was no association between having consulted a doctor in the previous year and decompensated blood pressure values. The proportion of decompensated hypertensive participants was significantly lower among those who had received guidance on ideal weight maintenance and physical activity practice and those who had had an electrocardiogram performed. The following factors were associated with decompensated hypertension: to be male, to be aged more than 40 years and to live in the South region.OBJETIVO: Estimar la prevalencia de acciones de promoción, prevención y cuidado de la hipertensión arterial en adultos e identificar la asociación con el estado descompensado de hipertensión.
