INTRODUCTION The aim of this study was to assess results of 6MWT in non-selected group of obstructive sleep apnoea (OSA) patients. In healthy adult subjects 6-minute walking distance (6MWD) range from 400 to 700 m. Obesity, the main symptom of OSA, is one of the factors associated with reduction of 6MWD (another common factors: older age, shorter height, female sex, pulmonary, cardiovascular an...

AIMS Previous studies have identified four baseline characteristics associated with a favourable response to cardiac resynchronization therapy (CRT): female, non-ischaemic aetiology of heart failure, left bundle-branch block (LBBB), and QRS duration ≥150 ms. This study evaluated the incremental value of discoordination and dyssynchrony indices over these characteristics for the prediction of th...

A Robust Dynamic Inversion (RDI) ight control law is designed for a large civil aircraft. Classical Dynamic Inversion (CDI) consists of a nonlinear part that linearizes the nominal system dynamics, and a linear part, basically PID control, that imposes the desired closed-loop dynamics. However, CDI controllers have very poor robustness properties since they rely on exact availability of the sys...

BACKGROUND Research has shown micronutrient deficiency to be scientifically linked to a higher risk of overweight/obesity and other dangerous and debilitating diseases. With more than two-thirds of the U.S. population overweight or obese, and research showing that one-third are on a diet at any given time, a need existed to determine whether current popular diet plans could protect followers fr...

IMPORTANCE Maxillomandibular advancement (MMA) is an invasive yet effective surgical option for obstructive sleep apnea (OSA) that achieves enlargement of the upper airway by physically expanding the facial skeletal framework. OBJECTIVE To identify criteria associated with surgical outcomes of MMA using aggregated individual patient data from multiple studies. DATA SOURCES The Cochrane Libr...

Artificial rich ore for blast furnace use can be produced by sintering ultra-poor vanadium-titanium magnetite (PVTM) with a high-grade iron concentrate. Here, acid (R = 0.33, 0.50), self-fluxing 1.10), and high-basicity 2.60) PVTM sinters were in sinter pot. Their performances determined using the comprehensive index. The microstructures of observed metallographic microscope scanning electron m...
