Modality-specific sensory changes in humans after the induction of long-term potentiation (LTP) in cutaneous nociceptive pathways.
2007
The impact of long-term potentiation (LTP) in nociceptive pathways on somatosensory perception was examined by means of quantitative sensory testing (QST) in the ventral forearm of 12 healthy human subjects. Electrical high-frequency stimulation of the forearm skin (HFS; 5 x 1 s at 100 Hz and 10 x detection threshold) led to an abrupt increase of pain to single electrical test stimuli, which were applied through the same electrode (perceptual LTP +72%, p0.01). Perceptual LTP outlasted the 1-h observation period. The effects of HFS on somatosensory perception of natural test stimuli in the conditioned skin area were restricted to mechanical submodalities. Subjects exhibited a significant dec…
The pattern and time course of somatosensory changes in the human UVB sunburn model reveal the presence of peripheral and central sensitization.
2013
The ultraviolet B (UVB) sunburn model was characterized with a comprehensive battery of quantitative sensory testing (QST). Primary hyperalgesia in UVB-irradiated skin and secondary hyperalgesia in adjacent nonirradiated skin were studied in 22 healthy subjects 24h after irradiation with UVB at 3-fold minimal erythema dose of a skin area 5 cm in diameter at the thigh and compared to mirror-image contralateral control areas. The time course of hyperalgesia over 96 h was studied in a subgroup of 12 subjects. Within the sunburn area, cold hyperesthesia (P=.01), profound generalized hyperalgesia to heat (P.001), cold (P.05), pinprick and pressure (P.001), and mild dynamic mechanical allodynia (…
A comparative study of the pharyngeal airway space, measured with cone beam computed tomography, between patients with different craniofacial morphol…
2014
Abstract Purpose The present study aims to determine any existing association between airway dimensions, measured with cone beam computed tomography (CBCT), and the different patient craniofacial morphologies. Material and methods Sixty CBCT (Dental Picasso Master 3D) images, from patients treated at the Orthodontics Master at Valencia University were selected. The program InVivoDental 5.1 was used to visualize sections, analyze three-dimensional images, and perform airway measurements in the three planes of the space. Intra- and interobserver error methods were recorded. After that, measurements at three different levels of the airway (upper, medium, lower) were taken, in both the anteropo…
The association between time scarcity, sociodemographic correlates and consumption of ultra-processed foods among parents in Norway: a cross-sectiona…
2017
Background Use of ultra-processed foods has expanded rapidly over the last decades and high consumption has been positively associated with risk of e.g. overweight, obesity and type 2 diabetes. Ultra-processed foods offer convenience as they require minimal time for preparation. It is therefore reasonable to assume that such foods are consumed more often among people who experience time scarcity. The main aim of this study was to investigate the association between time scarcity and consumption of ultra-processed foods among parents of 2-year olds in Norway. A secondary aim was to investigate the association between sociodemographic correlates, weight status and consumption of ultra-process…
A cross-sectional study of Health Related Quality of Life and body mass index in a Norwegian school sample (8-18 years): a comparison of child and pa…
2014
Background Because consequences of pediatric overweight and obesity are largely psychosocial, the aim of this study was to describe health related quality of life (HRQoL), the prevalence of overweight and obesity, and to examine the relationships between HRQoL and body mass index (BMI), age, and gender in a Norwegian sample of schoolchildren. In addition, because children are dependent upon their parents’ judgment of their condition, the aim was also to compare child- and parent-reported HRQoL and BMI, age, and gender. Methods This cross-sectional study involved 1238 children (8–18 years) and 828 parents. HRQoL was measured with the Norwegian version of the KIDSCREEN-52, child and parent ve…

Nature trips and traditional methods for food procurement in relation to weight status
2013
Author's version of an article in the journal: Scandinavian Journal of Public Health. Also available from the publisher at: http://dx.doi.org/10.1177/1403494812471446 Aims: The purpose of this study is to assess the relationships between trips in nature, gathering of wild plants, fishing and hunting and weight status. Methods: Data from a cross-sectional questionnaire survey of 996 parents of sixth- and seventh-graders from 38 randomly chosen schools in two Norwegian counties. All data are self-reported: Weight and height (participants were considered as overweight if BMI were 25 or higher), family trips in nature (dichotomized into ayenonce a week vs. less than once a week), gathering of w…
Intergenerational Hazardous Alcohol Use and Area Factors: The HUNT Study, Norway
2015
Alcohol use among adolescents has been found to be associated with parental alcohol abuse, but it's relation to more prevalent forms of hazardous drinking patterns among parents has been less explored. Few studies have included area factors when investigating alcohol use across generations.The aims of this study were to investigate whether adolescent intoxication was associated with parental heavy episodic drinking (HED) and intoxication, area-level socioeconomic status (SES), and rates of area-level HED.General Estimation Equations (GEE) was applied to analyze data from the Nord-Trøndelag Health Study (2006-08) including 2,306 adolescents. Adolescent alcohol use was defined by self-reporte…
Why do parents' education level and income affect the amount of fruits and vegetables adolescents eat?
2008
Background: There are large socioeconomic disparities in food behaviours. The objective of the present study is to longitudinally explore socioeconomic disparities in adolescents’ fruit and vegetable (FV) intake and to assess mediators of the disparity. Methods: A longitudinal study containing 896 adolescents from 20 randomly selected elementary schools within two Norwegian counties (response rate 84%). Questionnaires were administered in May 2002 (mean age 12.5 years) and again in May 2005. FV intake was measured by four food frequency questions (times/week). Socioeconomic status was based on parents’ reports of their own educational level and family income (both dichotomized). Data were a…
High-frequency oscillatory ventilation and an interventional lung assist device to treat hypoxaemia and hypercapnia
2004
A male patient accidentally aspirated paraffin oil when performing as a fire-eater. Severe acute respiratory distress syndrome ( P a 2 / F 2 ratio 10.7 kPa) developed within 24 h. Conventional pressure-controlled ventilation (PCV) with high airway pressures and low tidal volumes failed to improve oxygenation. Hypercapnia ( P a 2 12 kPa) with severe acidosis (pH<7.20) ensued. Treatment with high-frequency oscillatory ventilation (HFOV) and a higher adjusted airway pressure (35 cm H2O) improved the P a 2 / F 2 ratio within 1 h from 10.7 to 22.9 kPa, but the hypercapnia and acidosis continued. Stepwise reduction of the mean airway pressure (26 cm H2O), and oscillating frequencies (3.5 Hz), as …
