- The delivery of efficient nonpharmacological treatment to prevent the loss of muscle mass in older adults is a major challenge, and information on the combined effects of training and diet is particularly important. Here we aimed to evaluate the effects of 24 wk of resistance training combined with a healthy dietary approach (n-6/n-3 ratio < 2) in a population of healthy and physically active older women (65-70 years). The three-armed randomized controlled trial included a resistance training + healthy diet group (RT-HD), a resistance training group (RT), and controls (CON). All subjects included in the study were physically active and had low levels of serum inflammatory markers. In accordance with the dietary goals, the n-6/n-3 ratio dietary intake significantly decreased only in RT-HD by 42%. An increase in 1 repetition maximum in leg extension occurred in RT (+20.4%) and RT-HD (+20.8%), but not in CON. Interestingly, leg lean mass significantly increased only in RT-HD (+1.8%). While there were no changes in serum C-reactive protein and IL-6 levels, a significant decrease in serum level of the pro-inflammatory precursor arachidonic acid (-5.3 +/- 9.4%) together with an increase in serum n-3 docosahexaenoic acid (+8.3%) occurred only in RT-HD. Altogether, this study demonstrates that the effects of resistance training on muscle mass in healthy older adults can be optimized by the adoption of a healthy diet.

- 2009
-
In: European Journal of Nutrition. - Heidelberg, Germany : Springer. - 1436-6207 .- 1436-6215. ; 49:3, s. 141-146
-
Journal article (peer-reviewed)abstract
- Background: The single nucleotide polymorphism (SNP) LCT -13910 C>T, associated with genetically determined phenotypes of lactase persistence (LP) or non-persistence (LNP), was studied in relation to the metabolic syndrome (MS).AIim of the study: The aim was to determine if milk intake and MS are associated. We applied Mendelian randomization (MR). The SNP, LCT -13910 C>T, with the genotypes LP (TT/CT) and LNP (CC), was taken as a proxy for milk consumption.Methods: A representative sample of adults belonging to the Canary Islands Nutrition Survey (ENCA) in Spain aged 18-75 years (n = 551) was genotyped for the LCT -13910 C>T polymorphism. We used the International Diabetes Federation (IDF) criteria to define MS. RESULTS: 60% of the population was LP and 40% LNP. One hundred seven LP subjects (35.0%) and 53 LNP subjects (25.6%) showed MS (chi (2) = 5.04, p = 0.025). LP subjects showed a significantly higher odds ratio (OR) for MS than LNP subjects computed for the whole population: both the crude OR (1.56; 95% CI 1.06-2.31) and adjusted OR for sex, age, daily energy intake, physical activity and educational level (1.57; 95% CI 1.02-2.43). Adjusted OR for women with LP was 1.93; 95% CI 1.06-3.52.Conclusions: The T allele of the SNP might constitute a nutrigenetic factor increasing the susceptibility of LP subjects, especially women, to develop MS in the Canary Islands.

Body fat and dairy product intake in lactase persistent and non-persistent children and adolescents
- 2010
-
In: Food & Nutrition Research. - Järfälla, Sweden : Co-action Publishing. - 1654-6628 .- 1654-661X. ; 54
-
Journal article (peer-reviewed)abstract
- Background: Lactase non-persistent (LNP) individuals may be lactose intolerant and therefore on a more restricted diet concerning milk and milk products compared to lactase persistent (LP) individuals. This may have an impact on body fat mass.Objective This study examines if LP and LNP children and adolescents, defined by genotyping for the LCT-13910 C > T polymorphism, differ from each other with regard to milk and milk product intake, and measures of body fat mass.Design: Children (n=298, mean age 9.6 years) and adolescents (n=386, mean age 15.6 years), belonging to the Swedish part of the European Youth Heart Study, were genotyped for the LCT-13910 C > T polymorphism. Dietary intakes of reduced and full-fat dairy varieties were determined.Results: LNP (CC genotype) subjects consumed less milk, soured milk and yoghurt compared to LP (CT/TT genotype) subjects (p<0.001). Subsequent partitioning for age group attenuated this observation (p=0.002 for children and p=0.023 in adolescents). Six subjects were reported by parents to be 'lactose intolerant', none of whom were LNP. LNP children and adolescents consumed significantly less reduced fat milk and milk products than LP children and adolescents (p=0.009 for children and p=0.001 for adolescents).Conclusions: We conclude that LP is linked to an overall higher milk and dairy intake, but is not linked to higher body fat mass in children and adolescents.

Lactase persistence and milk consumption are associated with body height in Swedish preadolescents and adolescents
- 2011
-
In: Food & Nutrition Research. - : CoAction Publishing. - 1654-6628 .- 1654-661X. ; 55
-
Journal article (peer-reviewed)abstract
- Background: Body height is a classic polygenic trait. About 80%-90% of height is inherited and 10%-20% owed to environmental factors, of which the most important ones are nutrition and diseases in preadolescents and adolescents.Objective: The aim of this study was to explore potential relations between the LCT (lactase) C > T-13910 polymorphism, milk consumption, and body height in a sample of Swedish preadolescents and adolescents.Design: In a cross-sectional study, using a random sample of preadolescents and adolescents (n = 597), dietary intakes were determined. Anthropometric measurements including sexual maturity (Tanner stage) and birth weight were assessed. Parental body height and socio-economic status (SES) were obtained by questionnaires. Genotyping for the LCT C > T-13910 polymorphism that renders individuals lactase persistent (LP) or lactase non-persistent (LNP) was performed by DNA sequencing. Stepwise backward multivariate linear regression was used.Results: Milk consumption was significantly and positively associated with body height (beta =0.45; 95% CI: 0.040, 0.87, p =0.032). Adjustments were performed for sex, parental height, birth weight, body mass index (BMI), SES, and Tanner stage. This model explains 90% of the observed variance of body height (adjusted R-2 =0.89). The presence of the -13910 T allele was positively associated with body height (beta = 2.05; 95% CI: 0.18, 3.92, p =0.032).Conclusions: Milk consumption is positively associated with body height in preadolescents and adolescents. We show for the first time that a nutrigenetic variant might be able to explain in part phenotypic variation of body height in preadolescents and adolescents. Due to the small sample size further studies are needed.

Prevalence and trends in adult-type hypolactasia in different age cohorts in Central Sweden diagnosed by genotyping for the adult-type hypolactasia-linked LCT -13910C > T mutation
- 2007
-
In: Scandinavian Journal of Gastroenterology. - Oslo : Taylor & Francis. - 0036-5521 .- 1502-7708. ; 42:2, s. 165-170

Journal article (peer-reviewed)abstract
- OBJECTIVE: Adult-type hypolactasia (AtH) can be diagnosed by genotyping in addition to functional tests or intestinal biopsy. The aims of this study were to estimate the prevalence of AtH by genotyping and to investigate whether AtH prevalence has changed in Sweden during the 20th century. MATERIAL AND METHODS: Schoolchildren (n=690) born in 1983 and 1989, and elderly individuals (n=392) born between 1920 and 1932 were genotyped for AtH using Pyrosequencing technology. RESULTS: The overall prevalence of AtH among children was 14.1%. The majority of children (92%, n=635) were Caucasians with genotype prevalences: CC, 61 (10%); CT, 259 (41%); TT, 307 (49%). The frequency of the mutated allele q was 0.300 in this cohort. The prevalence of AtH estimated from the Hardy-Weinberg equilibrium (HWE) (q 2), was 9.0% (95% CI: 6.7-11.2%). Eight percent (n=55) of the children were non-Caucasian; genotype prevalences were CC, 36 (66%); CT, 15 (27%); TT, 4 (7%). The prevalence of AtH in these children estimated from HWE was 62.5% (95% CI: 49.7-75.3%). The elderly subjects were all Caucasians. Their genotype prevalences were: CC, 20 (5%); CT, 166 (42%); TT, 206 (53%); the frequency of the mutated allele q was 0.262 and their AtH prevalence estimated from HWE was 6.8% (95% CI: 4.3-9.2%). CONCLUSIONS: The overall prevalence of AtH in children (14%) was higher than previously thought. Among Caucasians, higher figures were seen in children than in the elderly (9% versus 6.8%). The prevalence thus seems to be increasing and this may be due to the immigration of both non-Caucasian and Caucasian groups with a higher prevalence of AtH.

Differential CSF biomarker levels in APOE-epsilon4-positive and -negative patients with memory impairment.
- 2007
-
In: Dementia and geriatric cognitive disorders. - Basel : S. Karger AG. - 1420-8008 .- 1421-9824. ; 23:2, s. 87-95

Journal article (peer-reviewed)abstract
- OBJECTIVES: To investigate the relationships between episodic memory, APOE genotype, CSF markers (total tau, T-tau; phospho-tau, P-tau; beta-amyloid, Abeta42) and longitudinal cognitive decline. METHODS: 124 memory clinic patients were retrospectively divided into 6 groups based on (i) episodic memory function (Rey Auditory Verbal Learning Test, RAVLT): severe, moderate or no impairment (SIM, MIM or NIM), and (ii) APOE genotype (epsilon4+ or epsilon4-). CSF marker levels and cognitive decline were compared across groups. RESULTS: Episodic memory function, according to RAVLT scores, was significantly correlated with CSF marker levels only among epsilon4+ subjects and not among epsilon4- subjects. When comparing the 6 subgroups, SIM epsilon4+ and MIM epsilon4+ groups showed significantly lower Abeta42 levels than the other groups. T-tau and P-tau levels were significantly increased in SIM epsilon4+ when compared to all the other groups, including the SIM epsilon4- group. However, both SIM epsilon4+ and SIM epsilon4- declined cognitively during the follow-up. CONCLUSION: It remains to be determined whether APOE genotype affects the expression of biomarkers in CSF, or whether the different biomarker patterns reflect different types of disease processes in patients with progressive cognitive dysfunction.

Journal article (peer-reviewed)abstract
- OBJECTIVES: To investigate whether application of cutoff levels in an episodic memory test (Rey Auditory Verbal Learning Test, RAVLT) is a useful method for identifying patients at high and low risk of cognitive decline and subsequent dementia. METHODS: 224 patients with memory complaints (mean age = 60.7 years, mean MMSE = 28.2) followed-up at a memory clinic over approximately 3 years were assigned retrospectively to one of three memory groups from their baseline results in RAVLT [severe (SIM), moderate (MIM) or no impairment (NIM)]. These groups were investigated regarding cognitive decline. RESULTS: Patients assigned to SIM showed significant cognitive decline and progressed to dementia at a high rate, while a normal performance in RAVLT at baseline (NIM) predicted normal cognition after 3 years. Patients with MIM constituted a heterogeneous group; some patients deteriorated cognitively, while the majority remained stable or improved. CONCLUSIONS: The application of cutoff levels in RAVLT at baseline showed that patients with severely impaired RAVLT performance were at a high risk of cognitive decline and progression to dementia, while patients with normal RAVLT results did not show cognitive decline during 3 years. Furthermore, the initial degree of memory impairment was decisive in the cognitive prognosis 3 years later.

Journal article (peer-reviewed)abstract
- BACKGROUND: Little is known about longitudinal changes of cerebrospinal fluid (CSF) biomarkers during cognitive decline in neurodegenerative disease progression. OBJECTIVE: To investigate longitudinal changes in CSF biomarkers--total-tau (T-tau), phospho-tau (P-tau) and beta-amyloid (Abeta42)--during cognitive decline. METHODS: Forty memory clinic patients (47.5% females), aged 61.3+/-7.6 (S.D.) years, non-demented at baseline, underwent lumbar puncture and neuropsychological testing at two occasions. Baseline mean MMSE-score was 28.3+/-1.8. Patients were divided into three groups based on baseline memory functioning; severely impaired (SIM), moderately impaired (MIM) and no impairment (NIM). RESULTS: There was a significant increase in P-tau in the SIM-group during follow-up, while P-tau in MIM and NIM did not change. Eighty-three percent of the SIM-patients converted to dementia (80% AD), while most MIM- and NIM-patients remained non-demented. T-tau- and Abeta42-levels did not change in any of the memory groups during follow-up. CONCLUSION: Increasing P-tau levels during cognitive decline and conversion to dementia suggest that P-tau may be useful as a longitudinal marker of the neurodegenerative process.

On the role of transversus abdominis in trunk motor control
- 2011
-
Doctoral thesis (other academic/artistic)abstract
- All trunk muscles are important contributors to spine stability. However, the deepest abdominal muscle, transversus abdominis (TrA), with its characteristically horizontal fibre orientation seems to serve a unique function in trunk motor control. The main mechanical role of TrA is believed to be to contribute to vertebral alignment during imposed moments on the trunk, executed mainly via either regulating the pressure level within the abdominal cavity and/or transmit forces to the spine via the thoracolumbar fascia. However, the complete function of TrA and what factors affect its activation are still not fully understood. The purpose of the present thesis was to investigate the role of TrA in trunk motor control, specifically in relation to the presence or absence of postural demand on the trunk.The timing and magnitude of TrA activation were investigated, in relation to other trunk muscles, with intramuscular fine-wire electrodes in different loading situations and body positions with varying postural demand.In a side-lying position, with no postural demand of keeping the trunk upright, the activation of TrA was delayed relative the superficial abdominal muscles compared to previous experiments performed in a standing position. The timing and magnitude of activation of TrA did not depend upon the direction of perturbation. In the standing position, different static arm positions revealed that the activation of TrA co-varied with variations in the degree of postural demand on the trunk and also the imposed moments, regardless of moment direction. Finally, a study on rapid arm flexion movements confirmed that TrA is part of the pre-programmed anticipatory response in advance of known perturbations. The activation magnitude of TrA was the same regardless if the arm movement induced flexion or extension moments on the trunk.In conclusion, the activation of TrA is associated with the upright postural demand on the trunk and with balancing imposed moments acting on the spine, regardless their direction. The findings are in support of the beliefs that TrA act as a general, direction non specific, stabilizer of the lumbar spine.

Methodology for measuring current distribution effects in electrochromic smart windows
- 2011
-
In: Applied Optics. - 1559-128X .- 2155-3165. ; 50:29, s. 5639-5646
-
Journal article (peer-reviewed)abstract
- Electrochromic (EC) devices for use as smart windows have a large energy-saving potential when used in the construction and transport industries. When upscaling EC devices to window size, a well-known challenge is to design the EC device with a rapid and uniform switching between colored (charged) and bleached (discharged) states. A well-defined current distribution model, validated with experimental data, is a suitable tool for optimizing the electrical system design for rapid and uniform switching. This paper introduces a methodology, based on camera vision, for experimentally validating EC current distribution models. The key is the methodology's capability to both measure and simulate current distribution effects as transmittance distribution. This paper also includes simple models for coloring (charging) and bleaching (discharging), taking into account secondary current distribution with charge transfer resistance and ohmic effects. Some window-size model predictions are included to show the potential for using a validated EC current distribution model as a design tool.

Lactase persistence versus lactose intolerance : Is there an intermediate phenotype?
- 2016
-
In: Clinical Biochemistry. - : Elsevier. - 0009-9120 .- 1873-2933. ; 49:3, s. 248-252
-
Journal article (peer-reviewed)abstract
- Background: According to the prevailing theory about the genetic background to lactose intolerance, there are three genotypes but only two adult physiological phenotypes: lactase persistence in individuals with the CT and TT genotypes and lactase non-persistence in individuals with the CC genotype. However, analysis of lactase activity from intestinal biopsies has revealed three distinct levels of activity, suggesting that an intermediate physiological phenotype may exist.Aim: To assess possible disparities between different genotypes with regard to biomarkers of lactase activity and physical symptoms during an oral lactose load test.Methods: A retrospective study using an oral lactose load test (n=487). Concentrations of hydrogen in exhaled air and blood glucose were measured. Afterwards, subjects were asked to provide oral mucosa samples for genotyping and answer a questionnaire (participation rate 56%, n=274).Results: Mean hydrogen levels in exhaled air at 120min were significantly higher in the CT genotype than in the TT genotype. There was no significant difference in blood glucose levels between the two groups. Reported symptoms, with the possible exception of abdominal pain, were equally prevalent in both groups.Conclusions: Subjects with the CT and TT genotypes, hitherto classified as lactase-persistent, differ in their physiological response to lactose intake, indicating differences in phenotype which could have clinical significance.

Hirsutism and quality of life with aspects on social support, anxiety and depression
- 2013
-
Doctoral thesis (other academic/artistic)abstract
- Hirsutism is excessive hair growth in women. The prevalence is estimated at 5%. The aim of this thesis was to describe different aspects of how life is affected for women suffering from hirsutism. Both qualitative and quantitative methods were used. Study I showed that hirsutism deeply affects women’s experiences of their bodies in a negative way and was experienced as a life sorrow. In Study II the patient-physician relationship was described. The patient-physician relationship from the patient’s perspective was suboptimal, as most meetings included feelings of being rejected and even humiliation. In Study III the aim was to translate and psychometrically evaluate an instrument that measures perceived social support, “The Multidimensional Scale of Perceived Social Support” (MSPSS). The translation was performed according to WHO:s official process, and validation was performed in a sample that consisted of 281 participants, 127 women with hirsutism (main sample) and 154 nursing students. MSPSS had good psychometric properties with regard to factor structure, construct validity, internal consistency and reproducibility. Study IV described different aspects of HRQoL in the main sample, the correlation of anxiety, depression, level of hairiness, age and BMI. The F-G scores were dichotomized into minor (F-G ≤14) and major (F-G≥15) hair growth. Higher levels of hair growth were significantly correlated to a lower level of QoL measured by DLQI, EQ-5D and symptoms of both anxiety and depression measured by HADS. Study V investigated if social support was associated with quality of life and outcome of HRQoL compared to a reference group of women (n=1115). SF-36, the MSPSS and the F-G scale were used. Compared to the reference group, women with hirsutism reported lower quality of life in all dimensions of SF-36 (p<0.01) The dimension most affected was vitality (VT=41.2), which had a lower value than has been reported for patients with MS and myasthenia gravis. A Multiple Regression Analysis showed a significant relation between quality of life and social support, indicating its importance for the ability to adapt, in spite of low quality of life.

Multicenter patch testing with methylchloroisothizoline/methylisothiazolinone in 100 and 200 ppm within the international contact dermatitis research group
- 2017
-
In: Dermatitis. - 1710-3568. ; 28:3, s. 215-218
-
Journal article (peer-reviewed)abstract
- Background: The preservative methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) is a well-known contact sensitizer. Historically, there have been different opinions on the optimal patch test concentration of MCI/MI, and both 0.01% and 0.02% aqueous (aq.) have been proposed. In 2011, based on literature reviews, it was recommended that the concentration of 0.02% aq. should be used in the international baseline series. Objectives: The aim of this study was to verify the recommendation from 2011 by comparing the patch test results from consecutive patch testing with MCI/MI 0.01% and 0.02% in clinics representing countries around the world. Patients and Methods: Two thousand seven hundred three consecutive patients with dermatitis in 8 dermatology clinics representing 8 countries were patch tested with MCI/MI 0.01% aq. and, in parallel with MCI/MI 0.02% aq., provisionally included in the baseline series. Results: Contact allergy to MCI/MI at 0.01% and 0.02% was found in 3.7% and 5.6% of the patients, respectively (P G 0.001). Conclusions: Methylchloroisothiazolinone/MI 0.02% aq. (dose, 6 Kg/cm2) diagnoses significantly more contact allergy than 0.01% (dose, 3 Kg/cm2), without resulting in more adverse reactions.Methylchloroisothiazolinone/MI at 0.02% aq. should therefore be continuously used in the international baseline series.

Low-intensity exercise increases skeletal muscle protein expression of PPARdelta and UCP3 in type 2 diabetic patients
- 2006
-
In: Diabetes/Metabolism Research Reviews. - : Wiley. - 1520-7552 .- 1520-7560. ; 22:6, s. 492-498
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Physical exercise provides health benefits for people with type 2 diabetes mellitus, partly by enhancing skeletal muscle insulin action. We tested the hypothesis that changes in expression of key genes in skeletal muscles relate to exercise-induced improvements in type 2 diabetic patients. METHODS: We determined mRNA expression of 20 selected genes following a self-supervised program of walking (> 150 min per week) over a 4-month period. RESULTS: This level of physical activity improved clinical parameters in approximately half the participants, as determined by reduced hypertension and enhanced insulin sensitivity (defined by reduced plasma-insulin levels and improved homeostasis model assessment (HOMA)). Skeletal muscle mRNA expression of Cbl-associated protein (CAP), diacylglycerol kinase (DGK)delta, uncoupling protein (UCP) 3, nuclear respiratory factor (NRF)-1, and peroxisome proliferator-activated receptor (PPAR)delta tended to increase in type 2 diabetic patients with an improved clinical profile. Skeletal muscle protein expression of PPARdelta and UCP3 was increased significantly after physical exercise in patients with an improved clinical profile, but were unchanged in patients who did not show exercise-mediated improvements in clinical parameters. CONCLUSIONS: This study provides clinical evidence that improvements in insulin sensitivity can be achieved in type 2 diabetic patients after individually executed low-intensity exercise training. Moreover, the positive clinical response to exercise is correlated with changes in skeletal muscle proteins involved in the regulation of mitochondrial biogenesis and metabolism. These changes in skeletal muscle gene expression offer a possible molecular explanation for the improvements in clinical outcomes.

Interventions for lifestyle changes to promote weight reduction, a randomized controlled trial in primary health care
- 2013
-
In: BMC Research Notes. - UK : BioMed Central Ltd.. - 1756-0500. ; 16:1
-
Journal article (peer-reviewed)abstract
- Background: Overweight and obesity are growing public health problems in high income countries and is now growing at a dramatic pace in low and middle income countries, particularly in urban settings. The aim of this trial was to examine the effects of a weight reduction program in adults and to determine whether or not a more extensive intervention was superior to ordinary care.Methods: Patients seeking advice for overweight/obesity or illness related to overweight/obesity at eight primary health care centers in Sweden were randomized either to intervention or control care groups with both groups given dietary advice and individualized information on increased regular physical activity. In the intervention group advice was more extensive and follow-up more frequent than in the control group during the study period of two years. Main outcome measure was reduction in body weight of five percent or more from study start.Results: From October 2004 to April 2006, 133 patients, 67 in the intervention group and 66 in the control group, were randomized over a period of 18 months. Target weight was achieved at 12 months by 26.7% of the patients in the intervention group compared with 18.4% in the control group (p = 0.335). There was an average absolute weight loss of 2.5 kg in the intervention group and 0.8 kg in the control group at 12 months as compared with the weight at study entry. There were no significant differences between the groups in quality of life, blood glucose and lipids. At 24 months target weight was achieved in 21.9% versus 15.6%, with an average weight reduction of 1.9 kg and 1.2 kg in the two groups, respectively.Conclusions: Promotion of a diet with limited energy intake, appropriate composition of food and increased physical activity had limited effects on body weight in a Swedish primary care setting. More extensive advice and more frequent visits made no significant difference to the outcome.

- The usefulness of non-specific inflammatory parameters for the diagnosis of community- acquired pneumonia (CAP) in primary care is not settled. The aim of this study was to assess the value of serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and white blood cell count (WBC) for this purpose. These inflammatory parameters, as well as the aetiological agents, were studied in 82 patients with radiologically confirmed CAP. CRP was elevated (>5 mg/l) in 76 patients, with a median value of 65 mg/l. 25 patients had a value of over 100 mg/l. In 32 patients the CRP levels were <50 mg/l and in 17 patients they were <20 mg/l. ESR varied from 5 to 100 mm/h, with a median value of 53 mm/h; in 21 patients the value was <30 mm/h. WBC varied from 4.4 to 21.4x10(9)/l, with a median value of 9.8x10(9)/l. No associations between the levels of the inflammatory parameters and the various aetiologies were found. It is concluded that the examined inflammatory parameters did not contribute notably in the routine diagnosis of CAP established by clinical measures.

Journal article (peer-reviewed)abstract
- Objective. The aim of the study was to assess the effect on prescription quality and quality of life after intervention with prescription reviews and promotion of patient participation in primary care. Design. A randomized controlled study with three groups: (A) controls, (B) prescription review sent to physician, and (C) as in B and with a current comprehensive medication record sent to the patient. Setting. The municipality of Orebro, Sweden (130 000 inhabitants). Intervention. The study focused on the easiest possible intervention to increase prescription quality and thereby increase quality of life. The intervention should be cost-efficient, focus on colleague-to-colleague advice, and be possible to perform in the primary health care centre without additional resources such as a pharmacist. Subjects. 150 patients recently discharged from hospital. Inclusion criteria were: andgt;= 75 years, andgt;= five drugs and living in ordinary homes. Main outcome measures. Quality of life (EQ-5D index, EQ VAS) and quality of prescriptions. Results. Extreme polypharmacy was common and persistent in all three groups and this was accompanied by an unchanged frequency of drug-risk indicators. There was a low EQ-5D index and EQ VAS in all three groups throughout the study. No statistically significant differences were found anywhere between the groups. Conclusion. The intervention seems to have had no effect on quality of prescriptions or quality of life. This underlines the major challenge of finding new strategies for improving prescription quality to improve patient outcome measures such as quality of life and reduce the known risks of polypharmacy for the elderly.

Medication quality and quality of life in the elderly, a cohort study
- 2011
-
In: Health and Quality of Life Outcomes. - : BioMed Central (BMC). - 1477-7525. ; 9
-
Journal article (peer-reviewed)abstract
- Background: Modern drugs have made large contributions to better health and quality of life. Increasing proportions of negative side effects due to extensive pharmacological treatment are however observed especially among elderly patients who have multiple health problems. The aim of our study was to see if there is an association between medication quality and quality of life.Methods: 150 patients discharged from hospital. Inclusion criteria were: living in ordinary homes, ≥ 75 years and ≥ 5 drugs. Home visits were performed to all, including prescription reviews and calculation of medication appropriateness index. The patients were divided into three groups depending on index score and followed for 12 months. The validated and recognized EQ-5D and EQ VAS instruments were used to assess quality of life.Results: A lower medication quality was associated with a lower quality of life. EQ-5D index was statistically significantly different (declining for each group) among the groups (p = 0.001 at study start, p = 0.001 at 6 months and p = 0.013 at 12 months) as was EQ VAS (p = 0.026 at study start, p = 0.003 at 6 months and p = 0.007 at 12 months).Conclusions: This study has shown the validity of the basic principle in prescribing: the more appropriate medication the better quality of life. Since drug quality is related to the patients’ quality of life, there is immense reason to continuously evaluate every prescription and treatment. The evaluation and if possible deprescribing should be done as a process where both the patient and physician are involved.

Journal article (peer-reviewed)abstract
- Purpose To examine whether patient focused drug surveillance was associated with a higher quality of drug treatment at nursing homes.Methods An intervention study in four nursing homes in Sweden and four other nursing homes served as controls. At the intervention nursing homes physicians focused on patients' health status as a baseline for further ongoing medication. The outcomes were mortality, health care consumption, and number of drugs, health status and evaluations as parameters for "quality of drug treatment".Results There were no significant differences in mortality rates. Healthcare consumption and polypharmacy were extensive in both groups. There was a significant reduction of number of drugs used per patient at the intervention homes during the study (p < 0.05). Monitoring and evaluation of the effects of medications were significantly more frequent at the intervention homes (p < 0.01).Conclusions The intervention resulted in significant positive results in relation to "quality of drug treatment", a shift in health care utilization with concomitant use of fewer drugs. The study showed an extreme shortage of monitoring of health status and surveillance of the effects of drugs in the elderly. Copyright (C) 2009 John Wiley & Sons, Ltd.

Rational drug treatment in the elderly : "To treat or not to treat"
- 2012

Doctoral thesis (other academic/artistic)abstract
- The general aim of this thesis was to examine the effect of interventions on the usage of inappropriate and hazardous multi-medication in the elderly ≥75 years with ≥5 drugs.Methods: Paper I describes a cluster randomization of nursing homes, the outcomes were; number of drugs, health status and evaluations. A randomized controlled trial concerning elderly in ordinary homes was performed in paper II and the outcomes were; EQ-5D index, EQ VAS and prescription quality. In paper III a cohort study was carried out and the outcomes were; medication appropriateness index, EQ-5D index and EQ VAS. In paper IV, registered nurses from the nursing homes study were interviewed in a descriptive study with a qualitative approach.Results:There was a significant reduction of number of drugs used per patient at the intervention nursing homes (p<0.05). Monitoring and evaluation of medications were significantly more frequent at the intervention homes (p<0.01). The registered nurses at the nursing homes described a self-made role in their profession and the leadership was not at sight. Drug treatment seems to be a passive process without own reflection. Extreme polypharmacy was persistent in all three groups of elderly living in ordinary homes and there was an unchanged frequency of drug-risk indicators. In the cohort study a lower medication quality was shown to be associated with a lower quality of life. EQ-5D index was statistically significantly different among the groups as was EQ VAS.Conclusion: The nursing home study showed an extreme shortage of monitoring of health status and surveillance of the effects of drugs in the elderly. More attention must be focused on the complexity of the nursing process; medication management must be promoted in teamwork with the physician. The resistance to change prescriptions in accordance with the intervention underlines the need of new strategies for improving prescription quality. Since medication quality is related to the patients’ quality of life, there is immense reason to continuously evaluate every prescription and treatment in shared decision with the patient.

Journal article (peer-reviewed)abstract
- Study Design. A cross-sectional study of physicians and physiotherapists in primary care. Objectives. To survey how familiar clinicians were with evidence-based guidelines for back pain and their opinion about their clinical usefulness and to compare self-reported practice behavior with the guidelines. Summary of Background Data. Guidelines, based on empirical evidence, are meant to ensure that patients get the most effective treatment. These evidence-based guidelines should steer clinical praxis, but clinicians may not read, let alone heed, them. Methods. Using a questionnaire, the authors surveyed all physicians and physiotherapists in primary health care in Örebro County, Sweden (N = 235). Results. Forty-two percent of the physicians and 37% of the physiotherapists were unfamiliar with the content of the guidelines, and 40% of the physicians and 25% of the physiotherapists were unfamiliar with the concept of 'red flags.' Less than half of the clinicians, 47%, were familiar both with the content of the guidelines and the concept of red flags. Their opinion about the guidelines showed that 54% of the physicians and 56% of the physiotherapists agreed that the guidelines were useful in clinical praxis. Concerning the self-reported practice behavior, the majority indicated that they followed the key points in the guidelines. Conclusions. A relatively large proportion of clinicians were unfamiliar with the content of evidence-based guidelines and/or with the concept of red flags. The process of implementing research into clinical practice is in need of an overhaul, and the impact of guidelines on clinical practice may be questioned.

Incidence of peritonsillar abscess and relationship to age and gender : Retrospective study
- 2008
-
In: Scandinavian Journal of Infectious Diseases. - London : Taylor & Francis. - 0036-5548 .- 1651-1980. ; 40:10, s. 792-796
-
Journal article (peer-reviewed)abstract
- The incidence of peritonsillitis is not very well known. A retrospective study was performed at the Ear, Nose and Throat clinic (ENT) at the University Hospital of Örebro Sweden. We studied every case from 2002 to 2004 and related it to a well-defined catchment area of 179,200 inhabitants. We identified 283 events of peritonsillitis, of which 85 were defined as peritonsillar cellulitis (PTC). Peritonsillar abscess (PTA) was found in 198 events in patients between 7 and 82 y of age. 13 patients had 2 episodes of PTA during the study period. The overall incidence was 37/100,000/y. The highest incidence was found between 14 and 21 y of age, with 124/100,000/y. The male: female ratio was 1: 1. Affected females were younger than males (p=0.04), and the peak incidence was earlier for females. This may be due to differences in immunological response, owing to hormonal maturation. The annual incidence of PTA was higher in this study than found in previous studies, which is probably attributable to the fact that our study identified almost all cases in the population.

In: Scandinavian Journal of Infectious Diseases. - : Informa UK Limited. - 0036-5548 .- 1651-1980. ; 42:10, s. 747-751
-
Journal article (peer-reviewed)abstract
- The microbiological cause of peritonsillar abscess and the role of group A beta-haemolytic Streptococcus (GAS) are unclear. We performed a retrospective study at the ear, nose and throat clinic (ENT) of Orebro University Hospital, Sweden, and included 376 events of peritonsillitis between 2002 and 2004. We determined if the patients had visited a primary healthcare centre (PHCC) within 30 days prior to inclusion. The results of the rapid antigen detection test for GAS (Strep A) taken at the PHCC were compared with the occurrence of peritonsillar abscess (PTA) and peritonsillar cellulitis (PTC). A Strep A test was performed in 61% (229/376) of the events studied. Strep A was positive in 22% of PTA events and in 35% of PTC events (p=0.036). Of 48,000 Strep A tests taken in primary healthcare, mainly for sore throat, 22% were positive. We examined the relationship between age, the incidence of PTA, and positive Strep A tests. We also determined if there was a monthly correlation between number of positive Strep A tests and number of PTA events. We found no significant correlations. In conclusion, our findings indicate that GAS does not play a major role in the development of PTA/PTC.

Validity of two questions of alcohol use in a health survey questionnaire
- 1999
-
In: Scandinavian Journal of Public Health. - : SAGE Publications. - 1403-4948 .- 1651-1905. ; 27:1, s. 73-77

Journal article (peer-reviewed)abstract
- The aim of this study was to investigate whether consumers of high and low levels of alcohol could be identified by two questions about alcohol use in a postal questionnaire survey. A sample of 2,300 persons aged 18 64 years from Stockholm county were sent a masked postal questionnaire comprising 30 questions about their health and functioning. Two questions concerned their alcohol consumption. One year later the subjects underwent a psychiatric health examination, which included an assessment of their alcohol use. The two questions about alcohol consumption identified high alcohol consumers with a relatively high sensitivity and specificity, of 64% and 87%, respectively, and thus are useful for identifying high alcohol consumers in health surveys using questionnaires.

Identification of novel genetic variants in the mutational hotspot region 14kb upstream of the LCT gene in a Mexican population
- 2017
-
In: Scandinavian Journal of Clinical and Laboratory Investigation. - : Taylor & Francis. - 0036-5513 .- 1502-7686. ; 77:5, s. 311-314
-
Journal article (peer-reviewed)abstract
- Several polymorphic loci linked to lactase persistence (LP) have been described, all located in a small mutational hotspot region far upstream (approximate to 14kb) of the lactase (LCT) gene. One is typically found in Europeans, LCT -13910C>T, several others are found in East Africans and Arabs, e.g. LCT -13907C>G and LCT -13915T>G. The possibility of similar loci, specific to populations in South and Central America, has not received much attention so far. To identify possible novel polymorphisms in the mutational hotspot region, we sampled 158 subjects from a rural area in South-Central Mexico. DNA was isolated from serum, and Sanger sequencing of a 501bp region spanning the LCT -13910C>T hotspot was successfully performed in 150 samples. The frequency of the European-type LCT -13910T-allele was q=0.202, and 35% of the population was thus lactase-persistent (CT or TT). Sixteen novel genetic variants were found amongst 11 of the subjects, all were heterozygotes: seven of the subjects were also carriers of at least one LCT -13910T-allele. Thus, the mutational hotspot region is also a hotspot in the rural Mexican population: 11/150 subjects carried a total of 16 previously unknown private mutations but no novel polymorphism was found. The relationship between such novel genetic variants in Mexicans and lactase persistence is worthy of more investigation.

Management of patients with chronic obstructive pulmonary disease in primary health care : a study of a nurse-led multidisciplinary programme of pulmonary rehabilitation
- 2011
-
Doctoral thesis (other academic/artistic)abstract
- The aim of this thesis was to modify and evaluate effects, as well as todescribe experiences of a nurse-led multidisciplinary programme of pulmonaryrehabilitation in primary health care for patients with chronicobstructive pulmonary disease (COPD) and their next of kin.Interviews were performed with 12 COPD nurses about their experiencesof patient education (I). Forty-nine patients participated in the interventiongroup and 54 in the control group in a quasi-experimentalstudy which investigated the effects of the programme on functional capacity,quality of life and exacerbation frequency during one year (II).Interviews were performed related to the experiences of 20 patients whohad participated in the six-week programme (III) and the experiences of20 next of kin to the patients that had participated (IV).The results showed that COPD nurses fluctuated between security andinsecurity in patient education and were in need of support, time, structureand collaboration to develop their patient education (I). In Study IIthere were no differences between the groups with regard to functionalcapacity and quality of life, but the number of exacerbations decreased inthe intervention group and increased in the control group (II). The patientsin study III had allowed themselves to live at their own pace followingthe programme but a constant fear was present in spite of the programme(III). Next of kin in Study IV had a life that remained overshadowedby illness but there were positive outcomes of the programme aslong as two years afterwards. The next of kin also had constant fear,however (IV).In conclusion, the six week programme brought about results in changingeveryday life. Nevertheless, all lived in the shadow of fear and uncertaintyin spite of the programme. More research is needed to address therequirements of COPD nurses, patients and next of kin.

Nurse-led multidisciplinary programme for patients with Chronic Obstructive Pulmonary Disease (COPD) in Primary Health Care
- 2010
-
Conference paper (peer-reviewed)abstract
- AIM: To investigate the effects of a nurse-led multidisciplinary programme (NMP) of pulmonary rehabilitation in primary health care with regard to functional capacity, quality of life (QoL), and exacerbations among patients with chronic obstructive pulmonary disease (COPD). METHOD: A 1-year longitudinal study with a quasi-experimental design was undertaken in patients with COPD, 49 in the intervention group and 54 in the control group. Functional capacity was assessed using the 6-minute walking test, and quality of life (QoL) was assessed using the Clinical COPD Questionnaire. Exacerbations were calculated by examination of patient records. RESULTS: No significant differences were found between the groups in functional capacity and QoL after 1 year. The exacerbations decreased in the intervention group (n = –0.2) and increased in the control group (n = 0.3) during the year after NMP. The mean difference of change in exacerbation frequency between the groups was statistically significant after one year (p=0.009). CONCLUSIONS: The NMP in primary care produced a significant reduction in exacerbation frequency, but functional capacity and QoL were unchanged. More and larger studies are needed to evaluate potential benefits in functional capacity and QoL.
