Malnutrition Reduces Quality of Life and Performance in Hospitalized Elderly

Malnutrition is a disorder of nutritional status due to reduced nutrient intake or impaired metabolism. It comprises a broad spectrum of clinical conditions from mild to very severe and has serious implications for health, recovery from illness or surgery, and hospital costs. Malnutrition has been frequently described among the elderly in hospital patients; this condition is often underestimated and considered as one of the aspects of aging. In this paper, the authors measured the incidence of malnutrition and its consequences on general health, physical and mental performance in a cohort of elderly patients. 

A cross-sectional study was conducted in a geriatric inpatient unit. Three hundred patients admitted to the clinic who fulfilled the inclusion criteria were enrolled. Nutritional status was evaluated by Mini Nutritional Assessment (MNA) questionnaire, macro and micronutrients intake, anthropometric measures and biochemical parameters. Physical and mental performances were recorded by questionnaires. Muscular strength was measured by a hand dynamometer and clinical outcomes were recorded.

Patients with poor nutritional status have lower physical and mental performance as respect to well-nourished patients. Undernourished patients have longer hospitalization and worst outcomes. We observe a high prevalence of severe hypovitaminosis D and the intake of various micronutrients was severely unbalanced. The incidence of malnutrition was 25% (75 patients); 39% (119 patients) were at risk of malnutrition. MNA was inversely related with the length of hospital stay (R = -0.25, p = 0.012) and with Geriatric Depression Scale (GDS) (R = -0.56, p = 0.000), whereas directly related with cognitive performance measured through Mini Mental State Examination (MMSE) (R = 0.5, p = 0.000) and hand grip strength (R = 0.35, p = 0.000). 

In conclusion, it’s shown that malnutrition has an important role in determining elderly independence, physical and mental performance and in predicting health outcomes, hence the hospital teams have to pay great attention to this problem even in community dwelling elderly.

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton ...

Incorporation of High-Altitude Balloon Experiment in High School Science Classrooms

High-altitude balloon is a balloon, filled usually with helium or hydrogen that ascends into an area called “near space” or stratosphere. The most common type of high-altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. The mission of the High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate enabling technologies, and resolve critical acquisition, tracking, and pointing (ATP) and fire control issues in support of future space-based precision pointing experiments. The use of high-altitude balloons offers a relatively low-cost, low-vibration test platform, a recoverable and reusable payload, worldwide launch capability, and a 'near- space' emulation of the future space systems operational scenarios. More recently, several university...
