    • OBJECTIVES: To evaluate the long-term effects of two non-face-to-face treatment programmes for stress urinary incontinence (SUI) based on pelvic floor muscle training (PFMT).SUBJECTS AND METHODS: The present study was a randomized controlled trial with online recruitment of 250 community-dwelling women aged 18-70 years with SUI ≥ one time/week. Diagnosis was based on validated self-assessed questionnaires, 2-day bladder diary and telephone interview with a urotherapist. Consecutive computer-generated block randomization was carried out with allocation by an independent administrator to 3 months of treatment with either an internet-based treatment programme (n = 124) or a programme sent by post (n = 126). Both interventions focused mainly on PFMT. The internet group received continuous e-mail support from a urotherapist, whereas the postal group trained on their own. Follow-up was performed after 1 and 2 years via self-assessed postal questionnaires. The primary outcomes were symptom severity (International Consultation on Incontinence Questionnaire Short Form [ICIQ-UI SF]) and condition-specific quality of life (ICIQ-Lower Urinary Tract Symptoms Quality of Life [ICIQ-LUTSqol]). Secondary outcomes were the Patient Global Impression of Improvement, health-specific quality of life (EQ-visual analogue scale [EQ-VAS]), use of incontinence aids, and satisfaction with treatment. There was no face-to-face contact with the participants at any time. Analysis was based on intention-to-treat.RESULTS: We lost 32.4% (81/250) of participants to follow-up after 1 year and 38.0% (95/250) after 2 years. With both interventions, we observed highly significant (P < 0.001) improvements with large effect sizes (>0.8) for symptoms and condition-specific quality of life (QoL) after 1 and 2 years, respectively. No significant differences were found between the groups. The mean (sd) changes in symptom score were 3.7 (3.3) for the internet group and 3.2 (3.4) for the postal group (P = 0.47) after 1 year, and 3.6 (3.5) for the internet group and 3.4 (3.3) for the postal group (P = 0.79) after 2 years. The mean changes (sd) in condition-specific QoL were 5.5 (6.5) for the internet group and 4.7 the for postal group (6.5) (P = 0.55) after 1 year, and 6.4 (6.0) for the internet group and 4.8 (7.6) for the postal group (P = 0.28) after 2 years. The proportions of participants perceiving they were much or very much improved were similar in both intervention groups after 1 year (internet, 31.9% [28/88]; postal, 33.8% [27/80], P = 0.82), but after 2 years significantly more participants in the internet group reported this degree of improvement (39.2% [29/74] vs 23.8% [19/80], P = 0.03). Health-specific QoL improved significantly in the internet group after 2 years (mean change in EQ-VAS, 3.8 [11.4], P = 0.005). We found no other significant improvements in this measure. At 1 year after treatment, 69.8% (60/86) of participants in the internet group and 60.5% (46/76) of participants in the postal group reported that they were still satisfied with the treatment result. After 2 years, the proportions were 64.9% (48/74) and 58.2% (46/79), respectively.CONCLUSION: Non-face-to-face treatment of SUI with PFMT provides significant and clinically relevant improvements in symptoms and condition-specific QoL at 1 and 2 years after treatment.

  • Usefulness of Symptoms to Screen for Celiac Disease
  • 2014
  • Ingår i: Pediatrics. - American Academy of Pediatrics. - 0031-4005. ; 133:2, s. 211-218
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To describe the frequency of symptoms and associated conditions among screening-detected celiac disease (CD) cases and non-CD children and to evaluate questionnaire-based case-finding targeting the general population. METHODS: In a population-based CD screening of 12-year-olds, children and their parents completed questionnaires on CD-associated symptoms and conditions before knowledge of CD status. Questionnaire data for those who had their CD detected in the screening (n = 153) were compared with those of children with normal levels of CD markers (n = 7016). Hypothetical case-finding strategies were also evaluated. Questionnaires were returned by 7054 ( 98%) of the children and by 6294 ( 88%) of their parents. RESULTS: Symptoms were as common among screening-detected CD cases as among non-CD children. The frequency of children with screening-detected CD was similar when comparing the groups with and without any CD-related symptoms (2.1% vs 2.1%; P =.930) or CD-associated conditions (3.6% vs 2.1%; P =.07). Case-finding by asking for CD-associated symptoms and/or conditions would have identified 52 cases (38% of all cases) at a cost of analyzing blood samples for 2282 children (37%) in the study population. CONCLUSIONS: The current recommended guidelines for finding undiagnosed CD cases, so-called active case-finding, fail to identify the majority of previously undiagnosed cases if applied in the general population of Swedish 12- year-olds. Our results warrant further studies on the effectiveness of CD case-finding in the pediatric population, both at the clinical and population-based levels.

  • Multiplex analyses of antibodies against citrullinated peptides in individuals prior to development of rheumatoid arthritis
  • 2013
  • Ingår i: Arthritis and Rheumatism. - Wiley-Blackwell. - 0004-3591. ; 65:4, s. 899-910
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: The presence of antibodies against cyclic citrullinated peptides has been demonstrated to precede the symptom onset of rheumatoid arthritis (RA) by several years. Antibodies against 10 citrullinated autoantigen-derived peptides were analysed for reactivity before onset of symptoms. METHODS: In the Medical Biobank of Northern Sweden 409 individuals were identified, of whom 386 provided 717 samples, obtained before onset of symptoms of RA (median time 7.4 (IQR 9.3) years); 1305 population based controls were also identified. Antibodies to 10 citrullinated peptides; fibrinogen (Fib) Fibα573, Fibα591, Fibß36-52, Fibß72, Fibß74, α-enolase (CEP-1), Type II Collagen citC1(III) , filaggrin, vimentin (Vim)2-17, and Vim60-75 were analysed using a microarray system. RESULTS: The antibody fluorescence intensity of Fibß36-52, Fibß74, CEP-1, citC1(III) , and filaggrin was significantly increased in pre-disease individuals compared with controls (p<0.001). The levels of the earliest detectable antibodies (Fibα591 and Vim60-75) fluctuated over time, with only a slight increase after onset of disease. Antibodies against Fibß36-52, CEP-1 and filaggrin increased gradually reaching the highest levels of all antibodies before symptom onset. A cluster of antibodies, citC1(III) , Fibα573 and Fibß74 increased only slightly before onset of symptoms but prominently after disease onset. The odds ratio for development of RA with a combination of CEP-1 and Fibß36-52 antibodies (<3.35 years pre-dating) was 38.8 (CI95%14.5-103.5) compared with having either. CONCLUSION: Development of an immune response towards citrullinated peptides is initially restricted but expands with time to induce a more specific response with increasing levels towards onset of symptoms, particularly invoving antibodies against CEP-1, Fibß36-52 and filaggrin.

  • Celiac disease revealed in 3% of Swedish 12-year-olds born during an epidemic
  • 2009
  • Ingår i: Journal of Pediatric Gastroenterology and Nutrition - JPGN. - New York : Raven P. - 0277-2116. ; 49:2, s. 170-176
  • Tidskriftsartikel (refereegranskat)abstract
    • Objetive: Sweden experienced a marked epidemic of celiac disease between 1984 and 1996 in children younger than 2 years of age, partly explained by changes in infant feeding. The objective of this study was to determine the prevalence of celiac disease in 12-year-olds born during the epidemic (1993), including both symptomatic and screening detected cases.Patients and methods: All sixth-grade children in participating schools were invited (n = 10,041). Symptomatic and, therefore, previously diagnosed celiac disease cases were ascertained through the National Swedish Childhood Celiac Disease Register and/or medical records. All serum samples were analyzed for antihuman tissue transglutaminase (tTG)-IgA (Celikey), and serum-IgA, and some for tTG-IgG and endomysial antibodies. A small intestinal biopsy was recommended for all children with suspected undiagnosed celiac disease.Results: Participation was accepted by 7567 families (75%). Previously diagnosed celiac disease was found in 67 children; 8.9/1000 (95% confidence interval [CI] 6.7-11). In another 192 children, a small intestinal biopsy was recommended and was performed in 180. Celiac disease was verified in 145 children, 20/1000 (95% CI 17-23). The total prevalence was 29/1000 (95% CI 25-33).Conclusions: The celiac disease prevalence of 29/1000 (3%)-with two thirds of cases undiagnosed before screening-is 3-fold higher than the usually suggested prevalence of 1%. When these 12-year-olds were infants, the prevailing feeding practice was to introduce gluten abruptly, often without ongoing breast-feeding, which might have contributed to this unexpectedly high prevalence.

  • Serum metabolite signature predicts the acute onset of diabetes in spontaneously diabetic congenic BB rats
  • 2011
  • Ingår i: Metabolomics. - Springer. - 1573-3882. ; 7:4, s. 593-603
  • Tidskriftsartikel (refereegranskat)abstract
    • The clinical presentation of type 1 diabetes is preceded by a prodrome of beta cell autoimmunity. We probed the short period of subtle metabolic abnormalities, which precede the acute onset of diabetes in the spontaneously diabetic BB rat, by analyzing the serum metabolite profile detected with combined gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS). We found that the metabolite pattern prior to diabetes included 17 metabolites, which differed between individual diabetes prone (DP) BB rats and their age and sex matched diabetes resistant (DR) littermates. As the metabolite signature at the 40 days of age baseline failed to distinguish DP from DR, there was a brief 10-day period after which the diabetes prediction pattern was observed, that includes fatty acids (e.g. oleamide), phospholipids (e.g. phosphocholines) and amino acids (e.g. isoleucine). It is concluded that distinct changes in the serum metabolite pattern predict type 1 diabetes and precede the appearance of insulitis in spontaneously diabetic BB DP rats. This observation should prove useful to dissect mechanisms of type 1 diabetes.

  • ICIQ symptom and quality of life instruments measure clinically relevant improvements in women with stress urinary incontinence
  • 2015
  • Ingår i: Neurourology and Urodynamics. - Wiley-Blackwell. - 0733-2467. ; 34:8, s. 747-751
  • Tidskriftsartikel (refereegranskat)abstract
    • AIMS: To determine whether changes in questionnaire scores on symptoms and condition-specific quality of life reflect clinically relevant improvements in women with stress urinary incontinence (SUI).METHODS: We retrospectively analyzed questionnaires collected during a randomized controlled trial in women with SUI, that received pelvic floor muscle training (PFMT) in two different formats. We included 218 women that answered validated self-assessment questionnaires at baseline and at a 4-month follow-up. We registered changes on two questionnaires, the International Consultation on Incontinence Modular Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) and the Lower Urinary Tract Symptoms Quality of Life (ICIQ-LUTSqol). We compared these score changes to responses from the Patient Global Impression of Improvement (PGI-I) questionnaire. Differences were analyzed with the Spearman rho and one-way-ANOVA. The minimum important difference (MID) was the mean change in score for women that experienced a small improvement.RESULTS: The PGI-I correlated significantly to both the ICIQ-UI SF (r = 0.547, P < 0.0001) and ICIQ-LUTSqol (r = 0.520, P < 0.0001). Thus, larger reductions in symptoms or quality of life scores were associated with greater impressions of improvement. The changes in ICIQ-UI SF and ICIQ-LUTSqol scores were significant across all PGI-I groups from "no change" to "very much improved" (P < 0.05). The MIDs were 2.52 (SD 2.56) for ICIQ-UI SF and 3.71 (SD 4.95) for ICIQ-LUTSqol.CONCLUSIONS: The change in ICIQ-UI SF and ICIQ-LUTSqol scores after PFMT reflected clinically relevant improvements in women with SUI. The MIDs established for this population may facilitate future research, treatment evaluations, and comparisons between studies.

  • Sleep apnoea is a common occurrence in females
  • 2013
  • Ingår i: European Respiratory Journal. - European Respiratory Society Journals. - 0903-1936. ; 41:3, s. 610-615
  • Tidskriftsartikel (refereegranskat)abstract
    • Obstructive sleep apnoea (OSA) is primarily regarded as a male disorder, presenting with snoring, daytime sleepiness and cardiovascular disease. We aimed to determine the frequency of sleep apnoea among females in the general population. We investigated 400 females from a population-based random sample of 10,000 females aged 20-70 yrs. They answered a questionnaire and performed overnight polysomnography. OSA (apnoea/hypopnoea index (AHI) >= 5) was found in 50% (95% CI 45-55%) of females aged 20-70 yrs. Sleep apnoea was related to age, obesity and hypertension, but not to daytime sleepiness. Severe sleep apnoea (AHI >= 30) was present in 14% (95% CI 8.1-21%) of females aged 55-70 yrs and in 31% (95% CI 12-50%) of obese females with a body mass index of >= 30 kg.m(-2) aged 55-70 yrs. Sleep apnoea with daytime sleepiness and sleep apnoea with hypertension were observed as two different phenotypes of OSA. OSA occurs in 50% of females aged 20-70 yrs. 20% of females have moderate and 6% severe sleep apnoea. Sleep apnoea in females is related to age, obesity and hypertension, but not to daytime sleepiness. When searching for sleep apnoea in females, females with hypertension or obesity should be investigated.

  • Cell specific chemotyping and multivariate imaging by combined FT-IR microspectroscopy and OPLS analysis reveals the chemical landscape of secondary xylem
  • 2011
  • Ingår i: The Plant Journal. - Blackwell Publishing Ltd. - 0960-7412. ; 66:5, s. 903-914
  • Tidskriftsartikel (refereegranskat)abstract
    • Fourier-transform infrared (FT-IR) spectroscopy combined with microscopy enables acquiring chemical information from native plant cell walls with high spatial resolution. Combined with a 64 x 64 focal plane array (FPA) detector 4096 spectra from a 0.3 x 0.3 mm image can be simultaneously obtained, where each spectrum represents a compositional and structural "fingerprint" of all cell wall components. For optimal use and analysis of such large amount of information, multivariate approaches are preferred. Here, FT-IR microspectroscopy with FPA detection is combined with orthogonal projections to latent structures discriminant analysis (OPLS-DA). This allows for 1) the extraction of spectra from specific cell types, 2) identification and characterization of different chemotypes using the full spectral information, and 3) further visualising the pattern of identified chemotypes by multivariate imaging. As proof of concept, the chemotypes of Populus tremula xylem cell types are described. The approach revealed unknown features about chemical plasticity and patterns of lignin composition in wood fibers that would have remained hidden in the dataset with traditional data analysis. The applicability of the method on Arabidopsis xylem, and its usefulness in mutant chemotyping is also demonstrated. The methodological approach is not limited to xylem tissues but can be applied to any plant organ/tissue also using other microspectroscopy techniques such as Raman- and UV-microspectroscopy.

  • Gender Differences and Predictors of Self-Rated Health Development Among Swedish Adolescents
  • 2011
  • Ingår i: Journal of Adolescent Health. - 1054-139X. ; 48:2, s. 143-150
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: The purpose of the study was to evaluate the development of self-rated health among boys and girls during adolescence. Methods: Longitudinal cohort study, involving 1,046 Swedish adolescents from the seventh (12-13 years old) to the ninth grade. Self-rated health (well-being) and health-related empowerment were measured using a questionnaire. Results: In the seventh as well as in the ninth grade, the proportion of adolescents reporting a good health was lower in girls than in boys. In general, girls showed lower health-related empowerment as compared with boys and this difference remained between both the grades. In boys and girls belonging to both grades, a high empowerment score was related to a high self-rated health. For both boys and girls, self-rated health declined between the seventh and ninth grade. In girls, the proportion rating their health as "very good" declined from 47 % to 30%, and in boys the same proportion declined from 56% to 46%, indicating an increasing gender difference. Only a minor proportion of adolescents (16% of the boys and 13% of the girls) reported an improvement. A high self-rated health in grade nine was, in girls, predicted by positive school experiences in seventh grade and, in boys, by a good mood in the family. Conclusion: During adolescence, girls reported lower self-rated health than boys and this gender difference increased over the years. High empowerment is related to high self-rated health, and positive school experiences and a good mood in the family seem to be important predictors of a positive development of self-rated health.
