Obstructive sleep apnea syndrome among obese individuals: A cross-sectional study

sem informaçãoThe obstructive sleep apnea syndrome (OSAS) is a respiratory illness, characterized by recurrent episodes of apnea and hypopnea, leading to reduction or cessation of the airflow. Obesity is one of the major risk factors for the development of OSAS. To hel6310862868sem informaçãosem informaçãosem informaçã

Dried brewers grains in growing rabbits: nutritional value and effects on performance

[EN] Two assays were carried out to determine i) the nutritional value of dried brewers’ grains and ii) the effects of inclusion of this ingredient in growing rabbit diets on animal performance and economic performance of the breeding unit. In the digestibility assay, a total of 28 male rabbits were distributed in 2 groups differing in the diet offered to animals: a reference diet (35.51% neutral detergent fibre and 16.50% crude protein [CP]) and a test diet (60% of reference diet and 40% of dried brewers grains). The dried brewers’ grain contained 37.9% of CP and 3371 kcal digestible energy/kg dry matter. In the performance study, 80 weaned rabbits (40 males and 40 females) were allotted at 40 d of age to 5 groups differing in the inclusion levels of dried brewers’ grains (0, 7, 14, 21 and 28%) from 40 d to 90 d of age. Inclusion of dried brewers’ grains did not affect the live weight at 90 d, the feed intake between 40 d and 90 d or the dressing percentage of rabbits (on average 223 g, 96 g/d and 51.3%, respectively). There was no effect of diet on the meat quality parameters (69.5% water holding capacity, 25.6% cooking loss, 3.4 kg/cm2 Warner-Bratzler shear force and pH 5.70) and inclusion levels above 14% reduced the feed cost (–18%; P<0.001), while inclusion above 21% improved net income (+32%; P<0.001). In conclusion, these results suggest that the use of dried brewers’ grains in diets for growing rabbits could improve the economic performance of the production system without impairing the animals’ performance.Lima, P.; Watanabe, P.; Cândido, R.; Ferreira, A.; Vieira, A.; Rodrigues, B.; Nascimento, G....

Repositioning of the global epicentre of non-optimal cholesterol

High blood cholesterol is typically considered a feature of wealthy western countries1,2. However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world3 and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which have different effects on human health4,5. However, the trends of HDL and non-HDL cholesterol levels over time have not been previously reported in a global analysis. Here we pooled 1,127 population-based studies that measured blood lipids in 102.6 million individuals aged 18 years and older to estimate trends from 1980 to 2018 in mean total, non-HDL and HDL cholesterol levels for 200 countries. Globally, there was little change in total or non-HDL cholesterol from 1980 to 2018. This was a net effect of increases in low- and middle-income countries, especially in east and southeast Asia, and decreases in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe. As a result, countries with the highest level of non-HDL cholesterol—which is a marker of cardiovascular risk—changed from those in western Europe such as Belgium, Finland, Greenland, Iceland, Norway, Sweden, Switzerland and Malta in 1980 to those in Asia and the Pacific, such as Tokelau, Malaysia, The Philippines and Thailand. In 2017, high non-HDL cholesterol was responsible for an estimated 3.9 million (95% credible interval 3.7 million–4.2 million) worldwide deaths, half of which occurred in east, southeast and south Asia. The global repositioning of lipid-related risk, with non-optimal cholesterol shifting from a distinct feature of high-income countries in northwestern Europe, north America and Australasia to one that affects countries in east and southeast Asia and Oceania should motivate the use of population-based policies and personal interventions to improve nutrition and enhance access to treatment throughout the world.</p

Nutritional status and accumulation of micronutrients in elephant grass cv. Roxo under rainfed conditions

The objective of this study was to evaluate the nutritional status and micronutrient accumulation run in the shoot of elephant grass cv. Roxo at different seasons under rainfed conditions. Seven growth ages (9, 18, 27, 36, 45, 54 and 63 days) and three growth seasons (rainy, transition and dry) were evaluated in a completely randomized design with split plots arrangement, where the ages were allocated in the plots and the seasons in the subplots, with three replications. It was observed interaction between growth ages x seasons for the contents and accumulations of iron (Fe), zinc (Zn), copper (Cu) and manganese (Mn). In the leaf, Fe (rainy and transition seasons), Zn, Cu and Mn (rainy season) reduced in response to the advancement in the growth age. In the dry season, the Fe content was linearly increased, while the Cu and Mn contents presented quadratic responses with increasing growth ages. The accumulations of Fe, Zn, Cu and Mn showed an increasing linear response with advancement in ages at all cultivation seasons. At 63 days of growth, Fe accumulations of 915.51, 463.93 and 360.00 g ha 1; Zn of 439.19, 111.48 and 86.37 g ha 1; Cu ratio of 56.07, 31.43 and 35.30 g ha 1 and Mn of 333.16, 155.78 and 225.40 g ha 1 (rainy, transition and dry seasons, respectively) were estimated. The accumulation of micronutrients in elephant grass cv. Roxo under rainfed presents the following order: Fe > Zn > Mn > Cu for the rainy and transition seasons, and Fe > Mn > Zn > Cu for the dry season.Se objetivó evaluar el estado nutricional y la dinamica de acumulación de micronutrientes en la parte aérea del pasto elefante cv. Morado en diferentes épocas bajo secano. Se analizarón siete edades de crecimiento (9, 18, 27, 36, 45, 54 y 63 días) y tres épocas de cultivo (lluviosa, transición y sequía), en un delineamiento completamente casualizado en el arreglo de parcelas subdivididas en el tiempo, las edades fueron asignadas en las parcelas y las épocas de cultivo en las subparcelas, con tres repeticiones. Se constató la interacción entre las edades de crecimiento y la época de cultivo para los contenidos y las acumulaciones de hierro (Fe), zinc (Zn), cobre (Cu) y manganeso (Mn). En la hoja, los niveles de Fe (épocas lluviosa y transición), Zn, Cu y Mn (época lluviosa) redujeron en respuesta al avance en la edad de crecimiento. En la época de sequía, el contenido de Fe fue incrementado linealmente, mientras que los niveles de Cu y Mn presentarón respuestas cuadráticas con el aumento de las edades de crecimiento. Los acúmulos de Fe, Zn, Cu y Mn presentarón una respuesta lineal creciente con el avance en las edades en todas las épocas de cultivo. A los 63 días de crecimiento, se estimaron acúmulos de Fe de 915.51, 463.93 y 360.00 g ha 1, Zn de 439.19, 111.48 y 86.37 g ha 1, Cu de 56.07, 31.43 y 35.30 g ha 1 y Mn de 333.16, 155.78 y 225.40 g ha 1 (épocas lluviosas, transición y sequía, respectivamente). La acumulación de micronutrientes en el pasto elefante cv. Morado manejado sobre secano presenta el siguiente orden Fe > Mn > Zn > Cu para las épocas lluviosas y de transición, y Fe > Mn > Zn > Cu para época de sequía
