Weight Gain Associated with Cinnarizine
1992
OBJECTIVE: To report four cases of cinnarizine-induced weight gain. DATA SOURCES: Case reports from a local obesity center and review articles. DATA EXTRACTION: Data were abstracted from spontaneous comments made by patients to one of the authors, who was a doctor at the clinic, and reviewed by the remaining authors. DATA SYNTHESIS: We reviewed the cases of four women, aged 50–57 years without endocrine or metabolic pathologies, that showed weight gain associated with the intake of cinnarizine for one to two years. No other drugs usually were administered during the period in which the women gained weight, although in two cases cinnarizine was associated with dihydroergocristine in the same…
DSP Implementation for Measuring the Loop Gain Frequency Response of Digitally Controlled Power Converters
2012
This paper presents a method for measuring the loop gain frequency response of digitally controlled power converters, without the need of any expensive measurement equipment such as frequency response analyzers (FRA). The method is based on the traditional perturbation and measurement scheme. The perturbation is internally synthesized by the DSP and applied as pulse-width modulation to the converter. The loop input and output data are sent to a PC via universal serial bus, which performs online the DFT of sent data. The perturbation amplitude is varied with frequency to improve signal-to-noise ratio of measurements. The number of cycles used to perform discrete Fourier transform calculation…
A Machine Learning Approach for Fall Detection Based on the Instantaneous Doppler Frequency
2019
Modern societies are facing an ageing problem that is accompanied by increasing healthcare costs. A major share of this ever-increasing cost is due to fall-related injuries, which urges the development of fall detection systems. In this context, this paper paves the way for the development of radio-frequency-based fall detection systems, which do not require the user to wear any device and can detect falls without compromising the user's privacy. For the design of such systems, we present an activity simulator that generates the complex path gain of indoor channels in the presence of one person performing three different activities: slow fall, fast fall, and walking. We have developed a mac…
Genetic influences on adult body mass index followed over 29 years and their effects on late-life mobility: a study of twin sisters.
2009
Background: The rise in body mass index (BMI) during adulthood increases the risk for metabolic disorders, functional limitations and disability in old age. This twin study examined prospectively whether genetic and environmental influences on women’s BMI also account for mobility 29 years later. Methods: The sample consisted of 103 monozygotic and 114 dizygotic pairs of twin sisters reared together. Body mass index was initially evaluated in 1975, when the women were aged 42.6±3.4 years, and was followed-up in 1981, 1990, 2001 and 2004. Mobility was evaluated using the standardised 6-minute walking test in 2001, when the women were aged 68.6±3.2 years, and followed-up 3 years later. An inv…
Associations between family-related factors, breakfast consumption and BMI among 10- to 12-year-old European children: the cross-sectional ENERGY-stu…
2013
Objective: To investigate associations of family-related factors with children's breakfast consumption and BMI-z-score and to examine whether children's breakfast consumption mediates associations between family-related factors and children's BMI-z-score. Subjects: Ten-to twelve-year-old children (n = 6374; mean age = 11.6 +/- 0.7 years, 53.2% girls, mean BMI-z-score = 0.4 +/- 1.2) and one of their parents (n = 6374; mean age = 41.4 +/- 5.3 years, 82.7% female, mean BMI = 24.5 +/- 4.2 kg/m(2)) were recruited from schools in eight European countries (Belgium, Greece, Hungary, the Netherlands, Norway, Slovenia, Spain, and Switzerland). The children self-reported their breakfast frequency per …

Also available from the publihser:http://dx.doi.org/10.1186/1479-5868-8-136 BACKGROUND:Insight in children's energy balance-related behaviours (EBRBs) and their determinants is important to inform obesity prevention research. Therefore, reliable and valid tools to measure these variables in large-scale population research are needed.OBJECTIVE:To examine the test-retest reliability and construct validity of the child questionnaire used in the ENERGY-project, measuring EBRBs and their potential determinants among 10-12 year old children.METHODS:We collected data among 10-12 yea…
EuropeaN Energy balance Research to prevent excessive weight Gain among Youth (ENERGY) project: Design and methodology of the ENERGY cross-sectional …
2011
Abstract Background Obesity treatment is by large ineffective long term, and more emphasis on the prevention of excessive weight gain in childhood and adolescence is warranted. To inform energy balance related behaviour (EBRB) change interventions, insight in the potential personal, family and school environmental correlates of these behaviours is needed. Studies on such multilevel correlates of EBRB among schoolchildren in Europe are lacking. The ENERGY survey aims to (1) provide up-to-date prevalence rates of measured overweight, obesity, self-reported engagement in EBRBs, and objective accelerometer-based assessment of physical activity and sedentary behaviour and blood-sample biomarkers…
Association of Gestational Weight Gain With Adverse Maternal and Infant Outcomes
2019
Importance: Both low and high gestational weight gain have been associated with adverse maternal and infant outcomes, but optimal gestational weight gain remains uncertain and not well defined for all prepregnancy weight ranges. Objectives: To examine the association of ranges of gestational weight gain with risk of adverse maternal and infant outcomes and estimate optimal gestational weight gain ranges across prepregnancy body mass index categories. Design, setting, and participants: Individual participant-level meta-analysis using data from 196 670 participants within 25 cohort studies from Europe and North America (main study sample). Optimal gestational weight gain ranges were estimated…

Spatial Allocation of European Structural Funds: What Is the Role of Strategic Interactions?
2020
This chapter explores the role of strategic interactions that affect the spatial allocation of structural funds in the European Union. More specifically, this chapter seeks to test if the interactions between government decisions are strategic substitutes or complements in the context of the European structural funds allocation. First, we present a theoretical model which depicts how the strategic interactions could affect the allocation of public grants in a bargaining process. Then, we test the direction of strategic interaction on the allocation of structural funds for the 2000–2006 programming period using spatial econometric techniques. We find a negative spatial interaction between Eu…
