Ultrasound Muscle Assessment and Nutritional Status in Institutionalized Older Adults: A Pilot Study

Muscle thickness, measured by ultrasonography, has been investigated for nutritional assessment in older adults, however the associations between muscle ultrasound parameters in the lower limb and nutritional status have not been studied. The aim of this study was to investigate the relationship between muscle thickness echo intensity (EI), and nutritional status in home care residents. A cross sectional study was conducted involving 19 older adults from a home care in Malaga (Spain). We evaluated lower leg muscles by ultrasound, anthropometric data, physical function (measured by gait speed and the Short Physical Performance Battery), strength (handgrip and knee extensors strength) and nutritional status across the Mini-Nutritional Assessment Short-Form (MNA-SF). We found that muscle thickness assessed by ultrasonography independently predicts nutritional status by MNA-SF and after adjusting for handgrip strength or age and sex. As secondary findings, we found relations between strength, functional capacity and the MNA-SF test. These results suggest that lower leg muscle ultrasound parameters could be used as a low-cost objective method for muscle evaluation in nutritional assessment in older adults

Decoupling Simulated Annealing From Massive Multiplayer Online Role-Playing Games in RAID

End-users agree that compact technology are an interesting new topic in the field of electri- cal engineering, and physicists concur. In fact, few futurists would disagree with the deploy- ment of Byzantine fault tolerance, demonstrates the structured importance of cryptography. We construct a novel algorithm for the simulation of write-ahead logging (JDL), validating that Byzantine fault tolerance can be made peer-to- peer, classical, and stable. It is often an important mission but is supported by previous work in the field

Maintained hand function and forearm bone health 14 months after an in-home virtual-reality videogame hand telerehabilitation intervention in an adolescent with hemiplegic cerebral palsy

Virtual reality videogames can be used to motivate rehabilitation, and telerehabilitation can be used to improve access to rehabilitation. These uses of technology to improve health outcomes are a burgeoning area of rehabilitation research. So far, there is a lack of reports of long-term outcomes of these types of interventions. The authors report a 15-year-old boy with hemiplegic cerebral palsy and epilepsy because of presumed perinatal stroke who improved his plegic hand function and increased his plegic forearm bone health during a 14-month virtual reality videogame hand telerehabilitation intervention. A total of 14 months after the intervention ended, repeat evaluation demonstrated maintenance of both increased hand function and forearm bone health. The implications of this work for the future of rehabilitation in children with neurological disabilities are discussed in this article

Predicting hand function in older adults: evaluations of grip strength, arm curl strength, and manual dexterity

Background Hand function is critical for independence in activities of daily living for older adults. Aims The purpose of this study was to examine how grip strength, arm curl strength, and manual dexterous coordination contributed to time-based versus self-report assessment of hand function in community-dwelling older adults. Methods Adults aged ≥60 years without low vision or neurological disorders were recruited. Purdue Pegboard Test, Jamar hand dynamometer, 30-second arm curl test, Jebsen-Taylor Hand Function Test, and the Late-Life Function and Disability Instrument were administered to assess manual dexterous coordination, grip strength, arm curl strength, time-based hand function, and self-report of hand function, respectively. Results Eighty-four adults (mean age = 72 years) completed the study. Hierarchical multiple regressions show that older adults with better arm curl strength (β = −.25, p < .01) and manual dexterous coordination (β = −.52, p < .01) performed better on the time-based hand function test. In comparison, older adults with better grip strength (β = .40, p < .01), arm curl strength (β = .23, p < .05), and manual dexterous coordination (β = .23, p < .05) were associated with better self-report of upper extremity function. Conclusions The relationship between grip strength and hand function may be test-specific. Grip strength becomes a significant factor when the test requires grip strength to successfully complete the test tasks. Arm curl strength independently contributed to hand function in both time-based and self-report assessments, indicating that strength of extrinsic muscles of the hand are essential for hand function

Dynamics of Population Growth

The objective of this project was to examine the dynamics of population size based on age-specific life history parameters, as well as on genetic information. Two basic models were developed and exercised based upon the Leslie Matrix. the first model examined different life history patterns and their impact on the resulting dynamics of population growth. The second model expanded the first to include different genotypes. The life history parameters, fecundity and survivorship, were the same for both models. Four fecundity patterns represented age-specific fecundity that is monotonically increasing, monotonically decreasing, constant, and peaking at an intermediate age; three survivorship patterns represented age-specific types (I, II, and III). From these age-specific life history characteristics, twelve fictitious data sets were created for each model. The genetic model was exercised to examine the genetic impact of immigrants on a population, which was otherwise genetically homogeneous. Impact was measured by the variation in allele frequency. These simulation results support the conjecture that some kinds of species, as defined by their life history characteristics, are especially susceptible to genetic perturbation
