Use of lambda-mu-sigma-derived Z score for evaluating respiratory impairment in middle-aged persons.
BACKGROUND The lambda-mu-sigma (LMS) method calculates the lower limit of normal for spirometric values as the 5th percentile of the distribution of Z scores. Conceptually, LMS-derived Z scores account for normal age-related changes in pulmonary function, including variability and skewness in reference data. Evidence is limited, however, on whether the LMS method is valid for evaluating respir...
متن کاملDepression among Middle-aged Persons
Metabolic syndrome (Mets) is a multifactorial disease characterized by abdominal obesity, elevated blood glucose, high blood pressure, and an altered lipid metabolism [1,2]. Development of Mets is associated with increasing age, inadequate physical activity, smoking, alcohol use, and high-fat or high-calorie diets [3,4]. The prevalence of Mets was 34.7% in 2011–2012 among Americans [5]. In part...
متن کاملReference Values for Spirometry Derived Using Lambda, Mu, Sigma (LMS) Method in Korean Adults: in Comparison with Previous References
BACKGROUND The present study aimed to update the prediction equations for spirometry and their lower limits of normal (LLN) by using the lambda, mu, sigma (LMS) method and to compare the outcomes with the values of previous spirometric reference equations. METHODS Spirometric data of 10,249 healthy non-smokers (8,776 females) were extracted from the fourth and fifth versions of the Korea Nati...
متن کاملRetinal microvascular abnormalities and cognitive impairment in middle-aged persons: the Atherosclerosis Risk in Communities Study.
BACKGROUND AND PURPOSE Cerebral microvascular disease has been hypothesized to contribute to cognitive impairment, but few clinical data are available. Here, we examine the relation of retinal microvascular abnormalities with cognitive function in middle-aged persons free of stroke. METHODS The Atherosclerosis Risk in Communities Study is a population-based study with examinations every 3 yea...
متن کاملSuperdeduction in Lambda-Bar-Mu-Mu-Tilde
Superdeduction is a method specially designed to ease the use of first-order theories in predicate logic. The theory is used to enrich the deduction system with new deduction rules in a systematic, correct and complete way. A proof-term language and a cut-elimination reduction already exist for superdeduction, both based on Christian Urban’s work on classical sequent calculus. However the compu...
