    Jaw-opening accuracy is not affected by masseter muscle vibration in healthy men2014Inngår i: Experimental Brain Research, ISSN 0014-4819, E-ISSN 1432-1106, Vol. 232, nr 11, s. 3501-3508Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    There is a functional integration between the jaw and neck regions with head extension-flexion movements during jaw-opening/closing tasks. We recently reported that trigeminal nociceptive input by injection of hypertonic saline into the masseter muscle altered this integrated jaw-neck function during jaw-opening/closing tasks. Thus, in jaw-opening to a predefined position, the head-neck component increased during pain. Previous studies have indicated that muscle spindle stimulation by vibration of the masseter muscle may influence jaw movement amplitudes, but the possible effect on the integrated jaw-neck function is unknown. The aim of this study was to investigate the effect of masseter muscle vibration on jaw-head movements during a continuous jaw-opening/closing task to a target position. Sixteen healthy men performed two trials without vibration (Control) and two trials with bilateral masseter muscle vibration (Vibration). Movements of the mandible and the head were registered with a wireless three-dimensional optoelectronic recording system. Differences in jaw-opening and head movement amplitudes between Control and Vibration, as well as achievement of the predefined jaw-opening target position, were analysed with Wilcoxon's matched pairs test. No significant group effects from vibration were found for jaw or head movement amplitudes, or in the achievement of the target jaw-opening position. A covariation between the jaw and head movement amplitudes was observed. The results imply a high stability for the jaw motor system in a target jaw-opening task and that this task was achieved with the head-neck and jaw working as an integrated system.

    Back pain in relation to musculoskeletal disorders in the jaw-face: a matched case-control study2007Inngår i: Pain, ISSN 0304-3959, E-ISSN 1872-6623, Vol. 131, nr 3, s. 311-319Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Back pain and temporomandibular disorders are both common conditions in the population with influence on the human motor system, but a possible co-morbidity between these conditions has not been fully investigated. The aim of this study was to test the hypothesis of an association between long-term back pain and pain and/or dysfunction in the jaw-face region. Back pain was defined as pain in the neck, shoulders and/or low back. The study-population comprised 96 cases with long-term back pain and 192 controls without back pain. We used a screening procedure, a questionnaire and a clinical examination of the jaw function. The questionnaire focused on location, frequency, duration, intensity and impact on daily life of symptoms in the jaw-face and back regions. The analysis was conducted on 16 strata, matched by age and sex for case vs. control, using Mantel-Haenszel estimates of matched odds ratio (OR) and 95% confidence interval (CI) as well as the corrected Mantel-Haenszel chi(2) test. The overall prevalence of frequent symptoms in the jaw-face region, as reported in the questionnaire, was 47% among cases and 12% among controls. The difference was statistically significant (P<0.0001) with a sevenfold odds ratio (CI: 3.9-13.7). Moderate to severe signs from the jaw region were clinically registered among 49% of the cases and 17% of the controls (P<0.0001, OR: 5.2, CI: 2.9-9.2). The results showed statistically significant associations between long-term back pain and musculoskeletal disorders in the jaw-face and indicate co-morbidity between these two conditions.

    Does a dose-response relation exist between spinal pain and temporomandibular disorders?2009Inngår i: BMC Musculoskeletal Disorders, ISSN 1471-2474, E-ISSN 1471-2474, Vol. 10, s. 28-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: The aim of this study was to test whether a reciprocal dose-response relation exists between frequency/severity of spinal pain and temporomandibular disorders (TMD). METHODS: A total of 616 subjects with varying severity of spinal pain or no spinal pain completed a questionnaire focusing on symptoms in the jaw, head and spinal region. A subset of the population (n = 266) were sampled regardless of presence or absence of spinal pain. We used two different designs, one with frequency/severity of spinal pain, and the other, with frequency/severity of TMD symptoms as independent variable. All 616 participants were allocated to four groups, one control group without spinal pain and three spinal pain groups. The subjects in the subset were allocated to one control group without TMD symptoms and three TMD groups. Odds ratios (ORs) were calculated for presence of frequent TMD symptoms in the separate spinal pain groups as well as for frequent spinal pain in the separate TMD groups. RESULTS: The analysis showed increasing ORs for TMD with increasing frequency/severity of spinal pain. We also found increasing ORs for spinal pain with increasing frequency/severity of TMD symptoms. CONCLUSION: This study shows a reciprocal dose-response-like relationship between spinal pain and TMD. The results indicate that these two conditions may share common risk factors or that they may influence each other. Studies on the temporal sequence between spinal pain and TMD are warranted.

    Effects of mouthrinses containing essential oils and alcohol-free chlorhexidine on human plaque acidogenicity.2010Inngår i: Clinical Oral Investigations, ISSN 1432-6981, E-ISSN 1436-3771, Vol. 14, nr 1, s. 107-112Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of this in vivo study was to evaluate the effect of two antimicrobial mouthrinses on dental plaque acidogenicity after a sucrose challenge. Twenty subjects, with a mean age of 59 years, participated in a double-blind intraindividual randomized study. Three mouthrinses were used in 16-day rinsing periods in addition to their regular mechanical oral hygiene: a solution with essential oils (EO), solution with alcohol-free chlorhexidine (CHX) and water (negative control). The three test periods were separated by 3-month washout periods. Changes in plaque acidogenicity were evaluated after a sucrose challenge at day 0 (baseline) and at day 17 of each mouthrinse period using the microtouch method. Both CHX and EO resulted at day 17 in statistically significant less attenuated pH falls compared to the water rinse. The CHX mouthrinse resulted in the least pronounced pH values compared with EO (ns) during the whole 30-min period. When calculated as area under the curve (AUC), significantly lower values (AUC(6.2) ) were found for CHX and EO at day 17 compared to day 0. A significant difference for AUC(6.2) between CHX and water was found at day 17. No statistically significant differences were found for any of the comparisons with AUC(5.7). The results from this study indicate that both the essential oils and the alcohol-free chlorhexidine reduced plaque acidogenicity after a sucrose challenge. Large interindividual variations were observed.

    Effect of essential oils containing and alcohol-free chlorhexidine mouthrinses on cariogenic micro-organisms in human saliva2013Inngår i: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 71, nr 3-4, s. 883-891Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective. The aim of this study was to evaluate the effect on mutans streptococci and lactobacilli in saliva of mouthrinsing with essential oils and an alcohol-free chlorhexidine. Materials and method. Twenty healthy volunteers (mean age 59 years) participated in the double-blind randomized cross-over study. Three mouthrinses were used in 16 days rinsing periods in addition to their regular mechanical oral hygiene: a solution with essential oils (EO; Listerine), a solution with alcohol-free chlorhexidine (CHX; Paroex) and water (negative control). The mouthrinse periods were separated by 3-month washout periods. At days 0 (baseline) and 17 (end) of each mouthrinse period, paraffin stimulated whole saliva was collected in order to analyse CFU/ml saliva of mutans streptococci and lactobacilli. Results. Only the CHX rinse showed a significant difference for CFU mutans streptococci between baseline and end (p = 0.004). The CFU mutans streptococci at the end of the rinse periods showed statistically significant differences between CHX vs EO (p = 0.039) and CHX vs water (p = 0.022). The difference in CFU lactobacilli between baseline and end was significant for CHX (p = 0.031), but not for the other rinses. No statistically significant differences for lactobacilli were found at the end of the rinse periods between the mouthrinses. Conclusion. A significant reduction in amount of cariogenic bacteria in saliva was observed after 16 days of alcohol-free chlorhexidine mouthrinse but not after the essential oils rinse. The high number of participant's not changing to a bacterial class with a reduced number of micro-organisms showed that both rinses had little clinical significance as a caries preventing treatment method, which can decrease the number of CFU cariogenic micro-organisms.

    Discovery and refinement of loci associated with lipid levels2013Inngår i: Nature Genetics, ISSN 1061-4036, E-ISSN 1546-1718, Vol. 45, nr 11, s. 1274-+Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Levels of low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, triglycerides and total cholesterol are heritable, modifiable risk factors for coronary artery disease. To identify new loci and refine known loci influencing these lipids, we examined 188,577 individuals using genome-wide and custom genotyping arrays. We identify and annotate 157 loci associated with lipid levels at P < 5 x 10(-8), including 62 loci not previously associated with lipid levels in humans. Using dense genotyping in individuals of European, East Asian, South Asian and African ancestry, we narrow association signals in 12 loci. We find that loci associated with blood lipid levels are often associated with cardiovascular and metabolic traits, including coronary artery disease, type 2 diabetes, blood pressure, waist-hip ratio and body mass index. Our results demonstrate the value of using genetic data from individuals of diverse ancestry and provide insights into the biological mechanisms regulating blood lipids to guide future genetic, biological and therapeutic research.

    Estrogen Receptor-alpha is required for the Osteogenic Response to mechanical loading in a Ligand-Independent manner involving its activation function 1 but Not 22013Inngår i: Journal of Bone and Mineral Research, ISSN 0884-0431, E-ISSN 1523-4681, Vol. 28, nr 2, s. 291-301Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Estrogen receptor-alpha (ER alpha) is crucial for the adaptive response of bone to loading but the role of endogenous estradiol (E2) for this response is unclear. To determine in vivo the ligand dependency and relative roles of different ERa domains for the osteogenic response to mechanical loading, gene-targeted mouse models with (1) a complete ERa inactivation (ER alpha(-/-)), (2) specific inactivation of activation function 1 (AF-1) in ER alpha (ER alpha AF-1(0)), or (3) specific inactivation of ER alpha AF-2 (ER alpha AF- 2(0)) were subjected to axial loading of tibia, in the presence or absence (ovariectomy [ovx]) of endogenous E2. Loading increased the cortical bone area in the tibia mainly as a result of an increased periosteal bone formation rate (BFR) and this osteogenic response was similar in gonadal intact and ovx mice, demonstrating that E2 (ligand) is not required for this response. Female ER alpha(-/-) mice displayed a severely reduced osteogenic response to loading with changes in cortical area (-78% +/- 15%, p < 0.01) and periosteal BFR (-81% +/- 9%, p < 0.01) being significantly lower than in wild-type (WT) mice. ER alpha AF-1(0) mice also displayed a reduced response to mechanical loading compared with WT mice (cortical area -40% +/- 11%, p < 0.05 and periosteal BFR -41% +/- 8%, p < 0.01), whereas the periosteal osteogenic response to loading was unaffected in ER alpha AF-2(0) mice. Mechanical loading of transgenic estrogen response element (ERE)-luciferase reporter mice did not increase luciferase expression in cortical bone, suggesting that the loading response does not involve classical genomic ERE-mediated pathways. In conclusion, ERa is required for the osteogenic response to mechanical loading in a ligand-independent manner involving AF-1 but not AF-2. (C) 2013 American Society for Bone and Mineral Research.

    Background: Overweight and obesity among adolescents are increasing worldwide. Risk factors include dietary intake characteristics and high levels of physical inactivity. In Sweden, few large comprehensive population-based surveys of dietary intake and lifestyle among adolescents have been carried out. Thus, the purpose of the current study was to describe dietary intake and food choices as well as leisure time activities in relation to overweight and obesity in a total sample of all schoolchildren aged 15 years in Western Sweden.

    Methods: In 2008, a questionnaire was sent to all 21,651 adolescents born in 1992 in Västra Götaland Region, Sweden. Participation rate was 54.3 % (50.7 % girls/49.3 % boys). The questionnaire included a 73-item semi-quantitative food frequency questionnaire and questions on lifestyle. Results were evaluated against the Nordic Nutrition Recommendations and Swedish indicators of healthy diet and exercise habits. Associations with concurrent overweight and obesity were evaluated in multiple linear regression analysis.

    Results: Among girls, 49.5 % reached the goal of consuming fruit and vegetables at least daily, whereas for boys the figure was 34.4 %. Among both sexes, 15 % reached the goal of consuming fish at least twice weekly. Two-thirds of both sexes reached the goal of regular moderate or vigorous physical activity weekly. In total, 12.4 % were overweight and 2.4 % were obese. More girls than boys were underweight, whereas more boys than girls were overweight or obese (p < 0.001). Boys exhibited a more frequent intake of sodas and concentrated fruit juices, milk 3 % fat, bread and potatoes and fast food (p < 0.001). Frequent intake of candies and chocolate was reported by both sexes. Among girls and boys, living in rural areas, living in apartments and reporting no frequent leisure time physical activity were significant risk factors for being overweight or obese, also when adjusted for other risk factors.

    Conclusions: Dietary habits of adolescents in Western Sweden warrant improvements. Public health actions should be taken to increase consumption of fruit, vegetables and fish, and decrease consumption of sodas and candies and also to increase frequency of physical activity. These actions may be helpful in reducing risks for overweight and obesity.

    More distinct food intake patterns among women than men in northern Sweden: a population-based survey2009Inngår i: Nutrition Journal, ISSN 1475-2891, E-ISSN 1475-2891, Nutrition journal, Vol. 8, nr 1, s. 1-9Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: The need to promote a healthy diet to curb the current obesity epidemic has today been recognized by most countries. A prerequisite for planning and evaluating interventions on dietary intake is the existence of valid information on long-term average dietary intake in a population. Few large, population-based studies of dietary intake have been carried out in Sweden. The largest to date is the Vasterbotten Intervention Program (VIP), which was initiated in 1985, with data collection still ongoing. This paper reports on the first comprehensive analyses of the dietary data and presents dietary intake patterns among over 60,000 women and men in northern Sweden during 1992-2005. METHODS: Between 1992 and 2005, 71,367 inhabitants in Vasterbotten county aged 30, 40, 50, and 60 years visited their local health care center as part of the VIP. Participants of VIP filled in an 84- or 64-item food frequency questionnaire (FFQ) and provided sociodemographic information. Complete and realistic information on consumption frequency was provided by 62,531 individuals. Food intake patterns were analyzed using K-means cluster analyses. RESULTS: The mean daily energy intake was 6,83 (+/-1,77) MJ among women and 8,71 (+/- 2,26) MJ among men. More than half of both women and men were classified as Low Energy Reporters (defined as individuals reporting a food intake level below the lower 95% confidence interval limit of the physical activity level). Larger variation in frequency of daily intake was seen among women than among men for most food groups. Among women, four dietary clusters were identified, labeled "Fruit and vegetables", "High fat", "Coffee and sandwich", and "Tea and ice cream". Among men, three dietary clusters were identified, labeled "Fruit and vegetables", "High fat", and "Tea, soda and cookies". CONCLUSION: More distinct food intake patterns were seen among women than men in this study in northern Sweden. Due to large proportions of Low Energy Reporters, our results on dietary intake may not be suitable for comparisons with recommended intake levels. However, the results on food intake patterns should still be valid and useful as a basis for targeting interventions to groups most in need.

    Defining the role of common variation in the genomic and biological architecture of adult human height2014Inngår i: Nature Genetics, ISSN 1061-4036, E-ISSN 1546-1718, Vol. 46, nr 11, s. 1173-1186Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Using genome-wide data from 253,288 individuals, we identified 697 variants at genome-wide significance that together explained one-fifth of the heritability for adult height. By testing different numbers of variants in independent studies, we show that the most strongly associated ∼2,000, ∼3,700 and ∼9,500 SNPs explained ∼21%, ∼24% and ∼29% of phenotypic variance. Furthermore, all common variants together captured 60% of heritability. The 697 variants clustered in 423 loci were enriched for genes, pathways and tissue types known to be involved in growth and together implicated genes and pathways not highlighted in earlier efforts, such as signaling by fibroblast growth factors, WNT/β-catenin and chondroitin sulfate-related genes. We identified several genes and pathways not previously connected with human skeletal growth, including mTOR, osteoglycin and binding of hyaluronic acid. Our results indicate a genetic architecture for human height that is characterized by a very large but finite number (thousands) of causal variants.

    The Effectiveness of Fluoride tablets. A Systematic Literature Review2016Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    The caries preventive effect of fluoride is well-known and the use of fluorides is considered an important part in caries preventive strategies. Several fluoride supplements are available today and can be adapted both on individual and on population-level. It is important to make sure that only supplements with scientifically proven effects are recommended for oral use as more fluoride products enter the market. The purpose of this systematic literature review was to identify and evaluate studies on the caries preventive effect from fluoride tablets published between 1 November 2001 and 1 February 2015. The Pubmed database was searched using MESH-terms and keywords. Studies meeting inclusion criteria were included in this study and reviewed in full-text. The reference lists of relevant studies were thoroughly searched for additional articles. A follow-up search was performed in April 2016 using the same method. The relevant articles were analysed with respect to study requirements and the evidence was graded according to the GRADE system. The literature search resulted in 604 articles, and 23 articles were reviewed in full-text. The outcome of the systematic literature search was 1 article of moderate quality and 2 articles of low quality. The scientific evidence regarding the caries preventive effect from fluoride tablets was of low-moderate quality. The effectiveness of fluoride tablets when used in caries prevention cannot be confirmed. This is due to noticeable differences in study design which makes it difficult to compare study results combined with insufficient scientific study quality.

    Endurance to physical strain in patients with temporomandibular disorders: a case-control study2012Inngår i: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, ISSN 1502-3850, Vol. 70, nr 6, s. 455-462Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Abstract Objective. The hypothesis tested was whether patients with temporomandibular disorders (TMD) have an impaired endurance to motor tasks, under physical strain. Material and methods. The study population included 81 cases with TMD and 75 controls. After giving their informed consent, the participants filled out a questionnaire and performed five endurance trials. Each trial was measured in seconds from start to termination. The tests included: (a) holding the arm in a straight out position with a 2 kg weight in the hand, (b) lifting and lowering the arm with a 2 kg weight in the hand, (c) opening and closing the mandible repeatedly against a resistance of 1.6 kg during the jaw-opening phase, (d) protruding and retracting the mandible repeatedly against a resistance of 1.6 kg during the protruding phase and (e) unilateral chewing of three pieces of chewing gum. Analysis of differences between cases and controls for endurance were evaluated with Mann-Whitney U-test. A p-value < 0.05 was considered statistically significant. Results. The cases had statistically significantly (p < 0.0001) lower endurance time than controls for all tests. Conclusions. Patients with TMD compared to those without signs and symptoms of TMD have an impaired capacity to endure motor tasks that involve physical demand of the jaw muscles and shoulder girdle muscles.

    Temporomandibular disorders among smokers and nonsmokers: a longitudinal cohort study2005Inngår i: Journal of Orofacial Pain, ISSN 1064-6655, E-ISSN 1945-3396, Vol. 19, nr 3, s. 209-217Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Aims: To evaluate whether smoking influences the presence and/or development of signs and symptoms of temporomandibular disorders(TMD) among adults.

    Methods: A random sample of subjects 35, 50 and 65 years of age was drawn from the general population and examined with the aid of a questionnaire and a clinical examination. Within the sample,. smokers were identified based on reported current smoking and nonsmokers were matched to the smokers based on age, gender, educational level, area of residence, and number of teeth. In total, 268 subjects were matched (134 pairs). Six years after the baseline examination, 122 matched pairs were re-examined.

    Results: Mild symptoms of TMD were reported by approximately 30% of the sample both at baseline and at the folllow-up examaination 6 years later. Pain in the jaws and/or more severe symptoms of TMD were reported by approximately 15% on both occasions. No significant differences between smokers and nonsmokers were found regarding symptoms of TMD. In both examinations, mild signs (dysfuntion index I) were found in approcimately 40% of the sample and moderate to severe signs (dysfunction index II to III) in approximately 20%; no statistically significant differences were found between smokers and nonsmokers. No significant differences were found between smokers and nonsmokers regarding the course of symptoms or signs of TMD during the study period.

    Conclusion: Smoking is not a factor related to the presence or development of signs and symptoms of TMD.

    Lower Jaw Movements Measured by Optoelectronic Movement Recording: A pilot study2018Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    Due to the complex nature of jaw movements, three-dimensional (3D) movement recording provide information about the jaw movement capacity. The aim of the present report was to test the reliability of measuring lower jaw movements using a 3D movement recording system and to calculate the lower jaw movement volume.

    Lower jaw movements, recorded by 3D optoelectronic movement analysis system (MacReflex®) was compared with reference values from a digital caliper. Pre-tests were performed to develop a software to calculate the lower jaw movements in separate dimensions and its volume. Pilot tests with two test persons followed to register the lower jaw movements and calculate lower jaw movement volume.

    The results indicate low reliability of lower jaw movements measured by movement recording system compared with reference values from digital caliper, reflected by delta values (D = max-min). The values from the movement recording system indicate high variability reflected by higher levels of standard deviation for movement recorded values compared with digital caliper and by percentage values calculated from the differences between mean values of movement recording and digital caliper. The calculated lower jaw movement volume was 10.3 cm3 and 17.2 cm3 for the test persons, respectively.

    Conclusively, the results imply that further testing of the method is needed with larger series and test-retest reliability analysis to evaluate the possibility to improve accuracy of tracing jaw movements with recording device. The 3D-movement recording system together with the software could be used for calculation of lower jaw movement volume but its accuracy could not be validated.

    Effects of fucosylated milk of goat and mouse on Helicobacter pylori binding to Lewis b antigen2004Inngår i: World Journal of Gastroenterology, ISSN 1007-9327, E-ISSN 2219-2840, Vol. 10, nr 14, s. 2063-2066Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Aim:To evaluate the effects of animal milk containing fucosylated antigens on Helicobacter pylori (H pylon) binding to Lewis b antigen.

    Methods:A mammary gland expression vector containing human α1-3/4-fucosyltransferase cDNA sequences was constructed. Transient expression of human(α1-3/4-fucosyltransferase cDNA in goat mammary cell and establishment of transgenic mice were performed. The adhesion inhibitory properties of milk samples were analyzed by using Hpylori.

    Results: Goat milk samples were found to inhibit bacterial binding to Lewis b antigen. The highest inhibition was observed 42 h after injection of the plasmid. The binding activity of Hpylori to Lewis b antigen reduced mostly, by 83%, however milk samples from transgenic mice did not inhibit Hpylori binding to Lewis b antigen.

    Conclusion: The use of “humanized“ animal milk produced by the transgenic introduction of fucosylated antigen can perhaps provide an alternative therapy and preventive measure for Hpylori infection.

    Induced Secretion of IL-1β from THP-1 Cells after Titanium Exposure2014Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Within the orthopedic field, a post-installation complication such as aseptic inflammation occurs around orthopedic prosthetic implants. Immunological studies within the field have so far been correlating the aseptic osteolytic process to activated macrophages due to phagocytosis of implant wear debris. The activated macrophages respond with an inflammasome mediated secretion of pro-inflammatory mediators Macrophage-polarization is another theory behind the mechanism of aseptic inflammation induced by orthopedic prosthetic implants, leading to a higher ratio of the pro-inflammatory subtype M1-macrophage in the local peri-implant tissue.

    Together with the lack of a true definition of peri-implantitis of dental implants, the mechanisms involved in the pathogenesis remain unravelled. Hence, the aim of our study was to investigate if mechanisms previously mentioned could be correlated to factors involved in pathogenesis of peri-implantitis. We hypothesized that samples of solid titanium and titanium-ions in combination with microbial stimuli could induce an enhanced pro-inflammatory interleukin-1β (IL-1β) secretion from macrophages. This hypothesis was tested in our in vitro experiments, where THP-1 cells (human monocyte cancer cell line) and freshly isolated human macrophages were exposed to solid titanium samples and titanium-ions in the presence of microbial stimuli (Escherichia coli LPS). Results showed that a pro-inflammatory response could be induced from THP-1 cells, due to exposure of titanium-metal and titanium-ions, dependent on the dose/purity of titanium. This indicates that a bacteria-induced inflammatory response could be further enhanced in vicinity to titanium implants.

    Discrimination between cases of duodenal ulcer and gastritis on the basis of putative virulence factors of Helicobacter pylori.2002Inngår i: Journal of Clinical Microbiology, ISSN 0095-1137, E-ISSN 1098-660X, Vol. 40, nr 6, s. 2244-2246Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The BabA, cagA, and vacA statuses of 827 Helicobacter pylori isolates were used in logistic regression models to discriminate duodenal ulcer from gastritis. Only BabA was a candidate for a universal virulence factor, but the low c statistic value (0.581) indicates that none of these factors were helpful in predicting the clinical presentation.

    Relationship of Actinobacillus actinomycetemcomitans serotype b to aggressive periodontitis: frequency in pure cultured isolates2004Inngår i: Journal of Periodontology, ISSN 0022-3492, E-ISSN 1943-3670, Vol. 75, nr 4, s. 592-599Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: To our knowledge, the association of the five serotypes of Actinobacillus actinomycetemcomitans (A. actinomycetemcomitans) to the new diagnostic classification scheme defined by the American Academy of Periodontology in 1999 has not yet been described. The goal of this study was to characterize the frequencies of the five serotypes of A. actinomycetemcomitans in A. actinomycetemcomitans isolates from various forms of periodontitis using both old and new diagnostic classifications and to determine the relationships between serotype and age and clinical diagnosis. METHODS: A total of 345 A. actinomycetemcomitans isolates from 115 A. actinomycetemcomitans culture-positive subjects (mean age 38.0 +/- 18.3 years, 59% female) were collected. Based on the new classifications, 33 subjects had aggressive periodontitis and 82 chronic periodontitis. According to old classifications, there were six prepubertal periodontitis (PPP), 12 localized juvenile periodontitis (LJP), 15 post-localized juvenile periodontitis (PLJP), 28 refractory periodontitis (Ref-P), and 54 adult periodontitis (AP) cases. Serotypes of A. actinomycetemcomitans were determined by an indirect immunofluorescence assay using serotype-specific polyclonal antisera to A. actinomycetemcomitans strains ATCC 29523, ATCC 43728, ATCC 33384, IDH 781 and IDH 1705 (serotype a, b, c, d, and e, respectively). Proportions of serotype b were examined between different diagnostic and age groups with a Z-test for proportions. RESULTS: Most subjects (n = 100, 86.96%) were infected with a single serotype (22 serotype a, 44 serotype b, 30 serotype c, 1 serotype d, and 3 serotype e). There were 11 subjects (9.57%) with two serotypes and two subjects (1.74%) with 3 serotypes. Two individuals had isolates lacking any detectable serotype antigen. Serotype b was the predominant serotype in children under 18 years of age and young adults between 19 to 35 years, although serotype b status was not significantly associated with age. Serotypes d and e were not found in patients under 35 years old. In 62 adult patients, one subject had serotype d and three had serotype e. Serotype b was the most common serotype in aggressive periodontitis (60.61%). The proportion of cases with serotype b was significantly higher in aggressive periodontitis compared to chronic periodontitis (P = 0.031). Other serotypes were not significantly associated with new diagnostic categories. Serotypes d and e were not detected in aggressive periodontitis. CONCLUSION: The results of this study show that proportions of serotype b of A. actinomycetemcomitans are significantly greater in culture-positive patients with aggressive periodontitis than those with chronic periodontitis.

    Thyroid receptor ligands. 1. Agonist ligands selective for the thyroid receptor beta1.2003Inngår i: Journal of Medicinal Chemistry, Vol. 24;46, nr 9, s. 1580-8Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Endogenous thyroid receptor hormones 3,5,3',5'-tetraiodo-l-thyronine (T(4), 1) and 3,5,3'-triiodo-l-thyronine (T(3), 2) exert a significant effects on growth, development, and homeostasis in mammals. They regulate important genes in intestinal, skeletal, and cardiac muscles, the liver, and the central nervous system, influence overall metabolic rate, cholesterol and triglyceride levels, and heart rate, and affect mood and overall sense of well being. The literature suggests many or most effects of thyroid hormones on the heart, in particular on the heart rate and rhythm, are mediated through the TRalpha(1) isoform, while most actions of the hormones on the liver and other tissues are mediated more through the TRbeta(1) isoform of the receptor. Some effects of thyroid hormones may be therapeutically useful in nonthyroid disorders if adverse effects can be minimized or eliminated. These potentially useful features include weight reduction for the treatment of obesity, cholesterol lowering for treating hyperlipidemia, amelioration of depression, and stimulation of bone formation in osteoporosis. Prior attempts to utilize thyroid hormones pharmacologically to treat these disorders have been limited by manifestations of hyperthyroidism and, in particular, cardiovascular toxicity. Consequently, development of thyroid hormone receptor agonists that are selective for the beta-isoform could lead to safe therapies for these common disorders while avoiding cardiotoxicity. We describe here the synthesis and evaluation of a series of novel TR ligands, which are selective for TRbeta(1) over TRalpha(1). These ligands could potentially be useful for treatment of various disorders as outlined above. From a series of homologous R(1)-substituted carboxylic acid derivatives, increasing chain length was found to have a profound effect on affinity and selectivity in a radioreceptor binding assay for the human thyroid hormone receptors alpha(1) and beta(1) (TRalpha(1) and TRbeta(2)) as well as a reporter cell assay employing CHOK1-cells (Chinese hamster ovary cells) stably transfected with hTRalpha(1) or hTRbeta(1) and an alkaline phosphatase reporter-gene downstream thyroid response element (TRAFalpha(1) and TRAFbeta(1)). Affinity increases in the order formic, acetic, and propionic acid, while beta-selectivity is highest when the R(1) position is substituted with acetic acid. Within this series 3,5-dibromo-4-[(4-hydroxy-3-isopropylphenoxy)phenyl]acetic acid (11a) and 3,5-dichloro-4-[(4-hydroxy-3-isopropylphenoxy)phenyl]acetic acid (15) were found to reveal the most promising in vitro data based on isoform selectivity and were selected for further in vivo studies. The effect of 2, 11a, and 15 in a cholesterol-fed rat model was monitored including potencies for heart rate (ED(15)), cholesterol (ED(50)), and TSH (ED(50)). Potency for tachycardia was significantly reduced for the TRbeta selective compounds 11a and 15 compared with 2, while both 11a and 15 retained the cholesterol-lowering potency of 2. This left an approximately 10-fold therapeutic window between heart rate and cholesterol, which is consistent with the action of ligands that are approximately 10-fold more selective for TRbeta(1). We also report the X-ray crystallographic structures of the ligand binding domains of TRalpha and TRbeta in complex with 15. These structures reveal that the single amino acid difference in the ligand binding pocket (Ser277 in TRalpha or Asn331 in TRbeta) results in a slightly different hydrogen bonding pattern that may explain the increased beta-selectivity of 15.

    Associations between craniomandibular disorders, sociodemographic factors and self-perceived general and oral health in an adult population2014Inngår i: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 72, nr 8, s. 1054-1065Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective. The aim of this study was to analyze the relationships between pain in the craniomandibular region and jaw dysfunction, respectively, to sociodemographic factors and self-perceived general and oral health in a middle-aged and elderly population in Västerbotten County, Sweden.

    Materials and methods. Six hundred individuals, 35-, 50-, 65- and 75 years old, from inland and 600 individuals from coastal areas were randomly selected in 2002. Of these, 987 individuals completed a questionnaire and 779 participated in a clinical examination. Thirty-five- and 50-year-olds together constituted a middle-aged group and the rest an elderly group.

    Results. Among the middle-aged, craniomandibular pain was associated with impaired general health status, signs of temporomandibular disorder (TMD) pain were associated with female gender and living alone, jaw dysfunction symptoms were associated with university degree and chewing with caution; and signs of TMD dysfunction were associated with female gender and living in the more densely populated coastal region. Among the elderly, craniomandibular pain was more common among those living in the inland region, craniomandibular pain and signs of TMD pain were associated with impaired general health status, jaw dysfunction symptoms were associated with higher education level and self-perceived impaired general health and oral health; and signs of TMD dysfunction were associated with female gender and living in the coastal region. Dental status was not associated with craniomandibular pain.

    Conclusions. Socioeconomic factors and impaired general state of health were related to signs and symptoms indicative of CMD. These factors may influence demand for treatment among the affected.

    Factors associated with clinical decision-making in relation to treatment need for temporomandibular disorders2016Inngår i: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 74, nr 2, s. 134-141Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective. The aim of this study was to analyze dentist's clinical decision-making related to treatment need for temporomandibular disorders (TMD) in an adult population. Materials and methods. The study population comprised 779 randomly selected 35, 50, 65 and 75 year old individuals living in the county of Vasterbotten, Sweden. The participants filled out a questionnaire and were examined clinically according to a structured protocol. The four examiners (two men, two women) were experienced dentists and were calibrated before the start of the study. After examination they individually assessed the need of treatment owing to TMD. Results. In total, 15% of the study population was considered to have a treatment need owing to TMD. The highest estimate was noted for 35 and 50 years old women and the lowest for 65 and 75 years old men. Overall, 21% of the women and 8% of the men were considered to have a treatment need owing to TMD, with statistically significant differences between men and women for the 35 and 50 years old groups. Inter-individual variations in dentists' decisions were observed. In a multivariate analysis, female gender, signs and symptoms of TMD pain, signs and symptoms of TMD dysfunction and smoking were associated with estimated treatment need. Conclusions. The prevalence of estimated treatment need owing to TMD was fairly high, but the dentists' clinical decision-making process showed large inter-individual variability. The observation calls for further research on the factors affecting the decision-making process in care providers.

    Prevalence of signs and symptoms indicative of temporomandibular disorders and headaches in 35-, 50-, 65- and 75-year-olds living in Västerbotten, Sweden2014Inngår i: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 72, nr 6, s. 458-465Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective. The aim of this study was to analyze and compare prevalence of signs and frequently occurring symptoms indicative of temporomandibular disorder (TMD) and headaches in 35-, 50-, 65- and 75-year-old men and women in Västerbotten County, Sweden.

    Materials and methods. From a total target population of 11 324 subjects living in Västerbotten County in the year 2002, 300 individuals in each age group were randomly selected. Of these, 998 (82% response rate) answered and returned a postal questionnaire and 779 (65% response rate) individuals accepted a clinical examination.

    Results. The prevalence of frequent TMD symptoms peaked among 50-year-old women and then declined. Women at this age reported significantly higher prevalence compared to men for all TMD symptoms except temporomandibular joint locking. In the 65- and 75-year-olds, the prevalence was practically equal between men and women as well as between these ages. Frequent headaches showed the highest prevalence among 35- and 50-year-old women, with a statistically significant difference between men and women of 50 years of age (p < 0.05). Fifty-year-old women had statistically significantly higher prevalence of muscle pain to palpation (p < 0.001), temporomandibular joint sounds (p < 0.01) and impaired maximal jaw opening capacity (p < 0.01), compared to 50-year-old men.

    Conclusions. The different symptoms indicative of TMD and headaches showed a similar pattern, with higher prevalence among the 35- and 50-year-old, as compared to the 65- and 75-year-old, participants. The pattern may be related to biological, psychosocial or generation-related factors.

    Bacterial DNA persists for extended periods after cell death2007Inngår i: Journal of Endodontics, ISSN 0099-2399, E-ISSN 1878-3554, Vol. 33, nr 12, s. 1417-1420Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The fate of DNA from bacteria that infect the root canal but cannot survive is currently unknown, yet such information is essential in establishing the validity of polymerase chain reaction (PCR)-based identification methods for root canal samples. This in vitro study tested the hypothesis that PCR-detectable DNA from dead bacteria might persist after cell death and investigated the efficiency of sodium hypochlorite (NaOCl) as a field decontamination agent. Using heat-killed Enterococcus faecalis, the persistence of DNA encoding the 16S rRNA gene was monitored by PCR. While most probable number analysis showed an approximate 1000-fold decay in amplifiable template, E. faecalis DNA was still PCR-detectable 1 year after cell death. NaOCl (1%) eliminated amplifiable DNA within 60 seconds of exposure. Our findings also disclosed a previously overlooked problem of concentration-dependent inhibition of the PCR reaction by thiosulfate-inactivated NaOCl. These results highlight the challenges of reliably identifying the authentic living root canal flora with PCR techniques.

    Does Caries Prevalence Correlate to Caries Risk in Adolescents on a Community Level?2015Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    An increasing geographical polarization of caries is seen among children and adolescents. Attitudes, lifestyle, socioeconomics, knowledge and use of fluorides are factors of significance for the dental health. The aim of this study was to assess selected risk factors and risk indicators for caries in adolescents from different parts of the county Halland with contrasting levels of caries.

    One hundred sixty-one adolescent in 9th grade in four public schools in Laholm (South) and Kungsbacka (North) were invited to participate. They were asked to fill in a questionnaire with 26 questions concerning oral health, attitudes, lifestyle and knowledge. Data were computerized in SPSS.

    In South the adolescents had more experience of dental care, more dental fear, a higher consumption of juice and used more fluoride tablets. In North the adolescents where more likely to choose natural science program, had learned to take care of their teeth by their parents and had received less orthodontic treatment. Knowledge about oral health between the two areas did not differ. In North the fluoride concentration in the piped drinking water was approximately 1.0 ppm while the corresponding value in South was < 0.3 ppm.

    In conclusion, the caries risk was higher in South with lower fluoride content in the piped drinking water and a higher consumption of fruit juice and lemonades and this was reflected in a higher caries experience. The consumption of sugary between meal products did not differ. Additionally, the adolescents in South reported more dental fear and orthodontic treatment were more common.

    Wireless optoelectronic recordings of mandibular and associated head-neck movements in man: a methodological study.2000Inngår i: Journal of Oral Rehabilitation, ISSN 0305-182X, E-ISSN 1365-2842, Vol. 27, nr 3, s. 227-238Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Human mandibular movements in space are the result of combined motions of the mandible and the head-neck. They can be simultaneously monitored by an optoelectronic recording technique via markers at different locations on the mandible and on the head. Markers can be attached to the teeth or to the facial skin. Mandibular movements relative to the head can be calculated by one- or three-dimensional (1D and 3D, respectively) mathematical compensation for head movements. The present study analysed mandibular and associated head movements during maximal jaw opening-closing tasks in 10 healthy subjects using a wireless 3D optoelectronic movement recording system. The study aimed to: (i) estimate the soft tissue related displacement of skin-attached markers at different locations on the face; (ii) compare 1D with 3D mathematical compensation for associated head movements; (iii) evaluate the influence of marker location on the recorded head and mandibular movement amplitudes; and (iv) compare skin-attached markers with teeth-attached markers with regard to temporal estimates of recorded mandibular and head movements. Markers were attached to the upper and lower incisors and to the skin of the forehead, nose-bridge, nose-tip and chin. Soft tissue related displacement of skin-attached markers varied between locations. The displacement for the chin marker was larger than that of other markers. The least displacement was found for the nose-bridge marker. However, relative to mandibular and head movements, respectively, the displacement of the chin marker was of the same order as that of the nose-bridge marker. The temporal estimates were not significantly affected by displacement of the skin-attached markers. Markers at different locations on the head and the mandible registered different amplitudes. The mandibular movement patterns calculated by 1D and 3D compensation were not comparable. It is concluded that markers attached to the chin and the nose-bridge can be reliably used in temporal analyses of mandibular and head movements during maximal jaw opening-closing. With certain limitations, they are acceptable for spatial analyses. Selection of method of marker attachment, marker location, and method of compensation for associated head movements should be based on the aim of the study.

    Effect of different head-neck-jaw postures on cervicocephalic kinesthetic sense2017Inngår i: Journal of Musculoskeletal and Neuronal Interactions - JMNI, ISSN 1108-7161, Vol. 17, nr 4, s. 341-346Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives: To investigate the effect of different induced head-neck-jaw postures on head-neck relocation error among healthy subjects.

    Methods: 30 healthy adult male subjects participated in this study. Cervicocephalic kinesthetic sense was measured while standing, habitual sitting, habitual sitting with clenched jaw and habitual sitting with forward head posture during right rotation, left rotation, flexion and extension using kinesthetic sensibility test.

    Results: Head-neck relocation error was least while standing, followed by habitual sitting, habitual sitting with forward head posture and habitual sitting with jaw clenched. However, there was no significant difference in error between different tested postures during all the movements.

    Conclusions: To the best of our knowledge, this is the first study to see the effect of different induced head-neck-jaw postures on head-neck position sense among healthy subjects. Assuming a posture for a short duration of time doesn’t affect head-neck relocation error in normal healthy subjects.

    Therapeutic Effects of Whole-Body Vibration Training in Knee Osteoarthritis: A Systematic Review and Meta-Analysis2015Inngår i: Archives of Physical Medicine and Rehabilitation, ISSN 0003-9993, E-ISSN 1532-821X, Vol. 96, nr 8, s. 1525-1532Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Objective: To examine the current evidence regarding the effects of whole-body vibration (WBV) training in individuals with knee osteoarthritis (OA). Data Sources: We searched PubMed, CINAHL, Embase, Scopus, Physiotherapy Evidence Database (PEDro), and Science Citation Index for research articles published prior to January 2015 using the keywords whole body vibration, vibration training, and vibratory exercise in combination with the Medical Subject Heading osteoarthritis knee. Study Selection: This meta-analysis was restricted to randomized controlled trials published in the English language. The quality of the selected studies was assessed by the PEDro Scale. The risk of bias was assessed using the Cochrane collaboration's tool in the domain-based evaluation. We also evaluated the quality of each study based on the criteria given by the International Society of Musculoskeletal and Neuronal Interactions for reporting WBV intervention studies, consisting of 13 factors. Data Extraction: Descriptive data regarding subjects, design, intervention, WBV parameters, outcomes, and conclusions were collected from each study by 2 independent evaluators. The mean and SD of the baseline and final endpoint scores for pain, stiffness, and function were extracted from the included studies. Data Synthesis: A total of 83 studies were found in the search. Of these, 5 studies met the inclusion criteria and were further analyzed. Four of these 5 studies reached high methodologic quality on the PEDro Scale. Overall, studies demonstrated mixed results in favor of additive effects of WBV for reducing pain and improving function in knee OA. There was considerable variation in the parameters of the WBV included in this systematic review. Conclusions: WBV training reduces pain and improves function in individuals with knee OA.

    Impaired positioning of the gape in whiplash-associated disorders.2006Inngår i: Swedish Dental Journal, ISSN 0347-9994, Vol. 30, nr 1, s. 9-15Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We have previously introduced a new concept for natural jaw function suggesting that "functional jaw movements" are the result of coordinated jaw and neck muscle activation, leading to simultaneous movements in the temporomandibular, atlanto-occipital and cervical spine joints. Thus, jaw function requires a healthy state of both the jaw and the neck motor systems. The aim of this study was to examine the positioning of the gape in space during maximal jaw opening at fast and slow speed in healthy as well as whiplash-associated disorders (WAD) individuals. A wireless optoelectronic technique for three-dimensional movement recording was used. Subjects were seated in an upright position, with back support up to the mid-scapular level without headrest. The position of the gape in space was defined as the vertical midpoint position of the gape at maximal jaw opening (MP). In healthy, the MP generally coincided with the reference position at the start of jaw opening. In the WAD group, the MP was significantly lower than the reference position. No sex or speed related differences were found. The results suggest that both the width and orientation of the gape in space relies on coordinated jaw and neck muscle activation and mandibular and head-neck movements. This study also suggests an association between neck pain and dysfunction following trauma, and reduced width and impaired positioning of the gape in space. Finally, the MP seems to be a useful marker in evaluation of the functional state of the jaw-neck motor system

    Perception about the importance and use of therapeutic massage as a treatment modality among physical therapists working in Saudi Arabia2015Inngår i: Journal of Physical Therapy Science, ISSN 0915-5287, Vol. 27, nr 6, s. 1827-1831Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    [Purpose] To report perceptions about the importance and use of therapeutic massage as a treatment modality among physical therapists working in Saudi Arabia. [Subjects and Methods] A 21-item structured questionnaire was used to assess various domains including the demographic and professional characteristics of physical therapists and their perceptions about the importance and use of therapeutic massage in their daily practice. The questionnaire was uploaded online and the web link was sent to 140 members of the Saudi Physical Therapy Association (SPTA). [Results] The overall response rate was 86%. Among the respondents, 31% reported occasional use of therapeutic massage in their clinical practice, and 55% reported to have received formal training for therapeutic massage. Use of therapeutic massage was more common among female physical therapists. [Conclusion] Many physical therapists working in Saudi Arabia consider therapeutic massage to be an important treatment modality, but its use is relatively limited, either due to the time and effort required to dispense it, or the lack of scientific evidence for its efficacy.

    Dietary intakes and food sources of phytoestrogens in the European Prospective Investigation into Cancer and Nutrition (EPIC) 24-hour dietary recall cohort2012Inngår i: European Journal of Clinical Nutrition, ISSN 0954-3007, E-ISSN 1476-5640, Vol. 66, nr 8, s. 932-941Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND/OBJECTIVES: Phytoestrogens are estradiol-like natural compounds found in plants that have been associated with protective effects against chronic diseases, including some cancers, cardiovascular diseases and osteoporosis. The purpose of this study was to estimate the dietary intake of phytoestrogens, identify their food sources and their association with lifestyle factors in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. SUBJECTS/METHODS: Single 24-hour dietary recalls were collected from 36 037 individuals from 10 European countries, aged 35-74 years using a standardized computerized interview programe (EPIC-Soft). An ad hoc food composition database on phytoestrogens (isoflavones, lignans, coumestans, enterolignans and equol) was compiled using data from available databases, in order to obtain and describe phytoestrogen intakes and their food sources across 27 redefined EPIC centres. RESULTS: Mean total phytoestrogen intake was the highest in the UK health-conscious group (24.9 mg/day in men and 21.1 mg/day in women) whereas lowest in Greece (1.3 mg/day) in men and Spain-Granada (1.0 mg/day) in women. Northern European countries had higher intakes than southern countries. The main phytoestrogen contributors were isoflavones in both UK centres and lignans in the other EPIC cohorts. Age, body mass index, educational level, smoking status and physical activity were related to increased intakes of lignans, enterolignans and equol, but not to total phytoestrogen, isoflavone or coumestan intakes. In the UK cohorts, the major food sources of phytoestrogens were soy products. In the other EPIC cohorts the dietary sources were more distributed, among fruits, vegetables, soy products, cereal products, non-alcoholic and alcoholic beverages. CONCLUSIONS: There was a high variability in the dietary intake of total and phytoestrogen subclasses and their food sources across European regions.

    Impact of thearubigins on the estimation of total dietary flavonoids in the European Prospective Investigation into Cancer and Nutrition (EPIC) study2013Inngår i: European Journal of Clinical Nutrition, ISSN 0954-3007, E-ISSN 1476-5640, Vol. 67, nr 7, s. 779-782Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Thearubigins (TR) are polymeric flavanol-derived compounds formed during the fermentation of tea leaves. Comprising similar to 70% of total polyphenols in black tea, TR may contribute majorly to its beneficial effects on health. To date, there is no appropriate food composition data on TR, although several studies have used data from the US Department of Agriculture (USDA) database to estimate TR intakes. We aimed to estimate dietary TR in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort and assess the impact of including TR or not in the calculation of the total dietary flavonoid intake. Dietary data were collected using a single standardized 24-h dietary recall interviewer-administered to 36 037 subjects aged 35-74 years. TR intakes were calculated using the USDA database. TR intakes ranged from 0.9 mg/day in men from Navarra and San Sebastian in Spain to 532.5 mg/day in men from UK general population. TR contributed <5% to the total flavonoid intake in Greece, Spain and Italy, whereas in the UK general population, TR comprised 48% of the total flavonoids. High heterogeneity in TR intake across the EPIC countries was observed. This study shows that total flavonoid intake may be greatly influenced by TR, particularly in high black tea-consuming countries. Further research on identification and quantification of TR is needed to get more accurate dietary TR estimations.

    Dietary flavonoid and lignan intake and gastric adenocarcinoma risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) study2012Inngår i: American Journal of Clinical Nutrition, ISSN 0002-9165, E-ISSN 1938-3207, Vol. 96, nr 6, s. 1398-1408Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Several experimental studies have suggested potential anticarcinogenic effects of flavonoids, although epidemiologic evidence for the impact of dietary flavonoids on risk of gastric cancer (GC) is limited. Objective: We investigated the association between intake of dietary flavonoids and lignans and incident GC. Design: The study followed 477,312 subjects (29.8% men) aged 35-70 y from 10 European countries who participated in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Validated dietary questionnaires and lifestyle information were collected at baseline. A food-composition database on flavonoids and lignans was compiled by using data from USDA and Phenol-Explorer databases. Results: During an average follow-up of 11 y, 683 incident GC cases (57.8% men) were mostly validated by a panel of pathologists and used in this analysis. We observed a significant inverse association between total flavonoid intake and GC risk in women (HR: 0.81; 95% CI: 0.70, 0.94; for the continuous variable after log2 transformation) but not in men (HR: 0.97; 95% CI: 0.85, 1.09). in women, significant inverse associations with GC risk were also observed for intakes of some flavonoid subgroups (anthocyanidins, flavonols, flavones, and flavanols), particularly with intestinal type tumors for total flavonoid and flavanol intakes (P-heterogeneity < 0.1). After stratification by smoking status and sex, there was no significant heterogeneity in these associations between ever- and never-smokers. Conclusion: Total dietary flavonoid intake is associated with a significant reduction in the risk of GC in women. Am J Clin Nutr 2012;96:1398-408.

    Differences in dietary intakes, food sources and determinants of total flavonoids between Mediterranean and non-Mediterranean countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study2013Inngår i: British Journal of Nutrition, ISSN 0007-1145, E-ISSN 1475-2662, Vol. 109, nr 8, s. 1498-1507Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A greater adherence to the traditional Mediterranean (MED) diet is associated with a reduced risk of developing chronic diseases. This dietary pattern is based on higher consumption of plant products that are rich in flavonoids. We compared the total flavonoid dietary intakes, their food sources and various lifestyle factors between MED and non-MED countries participating in the EPIC study. Flavonoid intakes and their food sources for 35 628 subjects, aged 35-74 years and recruited between 1992 and 2000, in twenty-six study centres were estimated using standardised 24 h dietary recall software (EPIC-Soft (R)). An ad hoc food composition database on flavonoids was compiled using analytical data from the United States Department of Agriculture and Phenol-Explorer databases. Moreover, it was expanded to include using recipes, estimations of missing values and flavonoid retention factors. No significant differences in total flavonoid mean intake between non-MED countries (373.7 mg/d) and MED countries (370.2 mg/d) were observed. In the non-MED region, the main contributors were proanthocyanidins (48.2 %) and flavan-3-ol monomers (24.9 %) and the principal food sources were tea (25.7 %) and fruits (32.8 %). In the MED region, proanthocyanidins (59.0 %) were by far the most abundant contributor and fruits (55.1 %), wines (16.7 %) and tea (6.8 %) were the main food sources. The present study shows similar results for total dietary flavonoid intakes, but significant differences in flavonoid class intakes, food sources and some characteristics between MED and non-MED countries. These differences should be considered in studies about the relationships between flavonoid intake and chronic diseases.

    Estimated dietary intakes of flavonols, flavanones and flavones in the European Prospective Investigation into Cancer and Nutrition (EPIC) 24 hour dietary recall cohort2011Inngår i: British Journal of Nutrition, ISSN 0007-1145, E-ISSN 1475-2662, Vol. 106, nr 12, s. 1915-1925Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Flavonols, flavanones and flavones (FLAV) are sub-classes of flavonoids that exert cardioprotective and anti-carcinogenic properties in vitro and in vivo. We aimed to estimate the FLAV dietary intake, their food sources and associated lifestyle factors in ten European countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. FLAV intake and their food sources for 36 037 subjects, aged between 35 and 74 years, in twenty-seven study centres were obtained using standardised 24 h dietary recall software (EPIC-SOFT). An ad hoc food composition database on FLAV was compiled using data from US Department of Agriculture and Phenol-Explorer databases and was expanded using recipes, estimations and flavonoid retention factors in order to increase its correspondence with the 24 h dietary recall. Our results showed that the highest FLAV-consuming centre was the UK health-conscious group, with 130.9 and 97.0 mg/d for men and women, respectively. The lowest FLAV intakes were 36.8 mg/d in men from Umea and 37.2 mg/d in women from Malmo (Sweden). The flavanone sub-class was the main contributor to the total FLAV intake ranging from 46.6 to 52.9% depending on the region. Flavonols ranged from 38.5 to 47.3% and flavones from 5.8 to 8.6%. FLAV intake was higher in women, non-smokers, increased with level of education and physical activity. The major food sources were citrus fruits and citrus-based juices (especially for flavanones), tea, wine, other fruits and some vegetables. We concluded that the present study shows heterogeneity in intake of these three sub-classes of flavonoids across European regions and highlights differences by sex and other sociodemographic and lifestyle factors.

    Estimation of the intake of anthocyanidins and their food sources in the European Prospective Investigation into Cancer and Nutrition (EPIC) study2011Inngår i: British Journal of Nutrition, ISSN 0007-1145, E-ISSN 1475-2662, Vol. 106, nr 7, s. 1090-1099Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Anthocyanidins are bioactive flavonoids with potential health-promoting effects. These may vary among single anthocyanidins considering differences in their bioavailability and some of the mechanisms involved. The aim of the present study was to estimate the dietary intake of anthocyanidins, their food sources and the lifestyle factors (sex, age, BMI, smoking status, educational level and physisical activity) involved among twenty-seven centres in ten European countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Anthocyanidin intake and their food sources for 36 037 subjects, aged between 35 and 74 years, in twenty-seven redefined centres were obtained using standardised 24 h dietary recall software (EPIC-SOFT). An ad hoc food composition database on anthocyanidins (cyanidin, delphinidin, malvidin, pelargonidin, peonidin, petunidin) was compiled using data from the US Department of Agriculture and Phenol-Explorer databases and was expanded by adding recipes, estimated values and cooking factors. For men, the total anthocyanidin mean intake ranged from 19.83 (SE 1.53) mg/d (Bilthoven, The Netherlands) to 64.88 (SE 1.86) mg/d (Turin, Italy), whereas for women the range was 18.73 (SE 2.80) mg/d (Granada, Spain) to 44.08 (SE 2.45) mg/d (Turin, Italy). A clear south to north gradient intake was observed. Cyanidins and malvidins were the main anthocynidin contributors depending on the region and sex. Anthocyanidin intake was higher in non-obese older females, non-smokers, and increased with educational level and physical activity. The major food sources were fruits, wine, non-alcoholic beverages and some vegetables. The present study shows differences in both total and individual anthocyanidin intakes and various lifestyle factors throughout Europe, with some geographical variability in their food sources.

    Dietary intakes and food sources of phenolic acids in the European Prospective Investigation into Cancer and Nutrition (EPIC) study2013Inngår i: British Journal of Nutrition, ISSN 0007-1145, E-ISSN 1475-2662, Vol. 110, nr 8, s. 1500-1511Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Phenolic acids are secondary plant metabolites that may have protective effects against oxidative stress, inflammation and cancer in experimental studies. To date, limited data exist on the quantitative intake of phenolic acids. We estimated the intake of phenolic acids and their food sources and associated lifestyle factors in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Phenolic acid intakes were estimated for 36 037 subjects aged 35-74 years and recruited between 1992 and 2000 in ten European countries using a standardised 24 h recall software (EPIC-Soft), and their food sources were identified. Dietary data were linked to the Phenol-Explorer database, which contains data on forty-five aglycones of phenolic acids in 452 foods. The total phenolic acid intake was highest in Aarhus, Denmark (1265.5 and 980.7 mg/d in men and women, respectively), while the intake was lowest in Greece (213.2 and 158.6 mg/d in men and women, respectively). The hydroxycinnamic acid subclass was the main contributor to the total phenolic acid intake, accounting for 84.6-95.3% of intake depending on the region. Hydroxybenzoic acids accounted for 4.6-14.4%, hydroxyphenylacetic acids 0.1-0.8% and hydroxyphenylpropanoic acids <= 0.1% for all regions. An increasing south-north gradient of consumption was also found. Coffee was the main food source of phenolic acids and accounted for 55.3-80.7% of the total phenolic acid intake, followed by fruits, vegetables and nuts. A high heterogeneity in phenolic acid intake was observed across the European countries in the EPIC cohort, which will allow further exploration of the associations with the risk of diseases.

    Age Related Differences in Muscle Fiber Composition and Capillary Supply of the Human Masseter Muscle2014Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The aim of the study was to test the hypothesis that aging causes changes in fiber composition and vascular supply in the human masseter muscle that contribute to impaired jaw function in elderly. The myosin heavy chain (MyHC) composition and capillary supply of muscle fibers in functionally different parts of the masseter muscle of six elderly and six young subjects (mean age 74 and 22 years) were analyzed with immunohistochemical and morphological methods.

    The mean muscle fiber area in the old masseter was decreased by 27% compared to the young subjects (1100 vs. 1507 m2, p=0.038). Smaller mean fiber area was observed for all fibers containing only slow MyHCI or fast MyHCII isoforms, but not for fibers co-expressing slow and fast MyHCs. There were no significant differences in the numbers of capillaries around fiber (CAF 1.85 vs. 1.92). When CAF was related to individual fiber area, capillaries around fiber area (CAFA), the capillary supply was significantly higher in elderly (CAFA 1.10 vs. 1.65, p=0.004). This was reflected by a higher capillary density in the old masseter (CD 574 vs. 794, cap/mm2, p=0.002).

    The loss of muscle mass without any reduction in capillary supply, suggests that the capillary network in the human masseter muscle is rather stable against degradation during aging. This finding is in contrast to previous findings in human limbs, where aging has been reported to decrease both fiber size and capillary network in muscles. We conclude that the ageing process might have different impact on jaw and limb muscles.
