    Measures used to quantify participation in childhood disability and their alignment with the family of participation-related constructs: a systematic review2018In: Developmental Medicine & Child Neurology, ISSN 0012-1622, E-ISSN 1469-8749, Vol. 60, no 11, p. 1101-1116Article in journal (Refereed)
    Abstract [en]

    AIM:

    We aimed to identify measures used to assess the participation of disabled children and to map the measures' content to the family of participation-related constructs (fPRC) to inform future research and practice.

    METHOD:

    Six databases were searched to identify measures used to assess participation in health, psychology, and education research. Included studies involved children aged 0 to 18 years with a permanent impairment or developmental disability and reported use of a quantitative measure of participation. A second search sought relevant literature about each identified measure (including published manuals) to allow a comprehensive understanding of the measure. Measurement constructs of frequently reported measures were then mapped to the fPRC.

    RESULTS:

    From an initial yield of 32 767 articles, 578 reported one or more of 118 participation measures. Of these, 51 measures were reported in more than one article (our criterion) and were therefore eligible for mapping to the fPRC. Twenty-one measures quantified aspects of participation attendance, 10 quantified aspects of involvement as discrete scales, and four quantified attendance and involvement in a manner that could not be separated.

    INTERPRETATION:

    Improved understanding of participation and its related constructs is developing rapidly; thoughtful selection of measures in research is critical to further our knowledge base.

    WHAT THIS PAPER ADDS:

    The fPRC can support our rapidly evolving and expanding understanding of participation. Instruments selected to measure participation do not always align with emerging concepts. Matching research aims to a chosen measure's content will improve understanding of participation. Opportunities exist to develop validated participation measures, especially self-reported measures of involvement.

    Increased mortality in the A/A genotype of the SNP rs28372698 of interleukin 322021In: Experimental and Therapeutic Medicine, ISSN 1792-0981, E-ISSN 1792-1015, Vol. 21, no 2, article id 127Article in journal (Refereed)
    Abstract [en]

    One of the major causes of mortality in the western hemisphere is cardiovascular disease. Therefore, a variety of markers to identify those at risk are required. Interleukin-32 (IL-32) is a cytokine that is associated with inflammation. The aim of the current study was to investigate variations in single nucleotide polymorphisms (SNPs) of IL-32 and plasma expression, and their associations with mortality. A population of 486 elderly community-living persons were evaluated. The participants were followed for 7.1 years and underwent a clinical examination and blood sampling. SNP analyses of IL-32 rs28372698 using allelic discrimination and plasma measurement of IL-32, using ELISA, were performed. During the follow-up period, 140 (28.8%) all-cause and 87 (17.9%) cardiovascular deaths were registered. No significant difference between mortality and plasma concentration of IL-32 was observed. The A/A genotype group exhibited significantly higher all-cause mortality (P=0.036), and an almost two-fold increased risk in a multivariate Cox regression model for all-cause and cardiovascular mortality. A highly significant difference in all-cause and cardiovascular mortality between the A/A and the T/T groups was demonstrated (P=0.015 resp. P=0.014). In the present study, the cytokine IL-32 was demonstrated to have prognostic information, with an increased risk of all-cause and cardiovascular mortality for those with the A/A genotype rs28372698 of IL-32. The A/A genotype could therefore be regarded as a possible biomarker for mortality risk that may be used to offer optimized cardiovascular patient handling in the future. However, the present study sample was small, and the results should be regarded as hypothesis-generating.

    Cigarette smoking affects microRNAs and inflammatory biomarkers in healthy individuals and an association to single nucleotide polymorphisms is indicated2019In: Biomarkers, ISSN 1354-750X, E-ISSN 1366-5804, Vol. 24, no 2, p. 180-185Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Cigarette smoke induces inflammation and remodels immune response. Genetic and epigenetic alterations might be involved in the pathogenesis of smoking related diseases. In this study, we investigated the effect of smoking on systemic inflammation biomarkers and epigenetic changes at microRNA (miRNA) expression level. We also examined if the levels of inflammatory biomarkers were associated with selected single nucleotide polymorphisms (SNPs).

    METHOD: From 39 smokers and 101 non-smokers, levels of total white blood cells (WBCs) and its subpopulations, plasma cytokines/chemokines/proteins and miRNAs were analysed. For three biomarkers, C-reactive protein (CRP), MCP-1 and IFN-γ that were affected by smoking, the influence of SNPs was analyzed.

    RESULT: Elevated levels of total WBCs, neutrophils, monocytes, lymphocytes, CRP, MCP-1, IFN-γ and lower levels of miR-21 were detected in smokers. The elevated levels of IFN-γ in smokers was only statistically significantly associated with rs2069705 AG/GG SNP-genotype.

    CONCLUSIONS: A lower level of oncomir miRNA-21 and a higher level of immune modelling cytokine IFN-γ detected in smokers could be a protective immune response to cigarette smoke. The higher level of IFN-γ in smokers with a specific SNP genotype also suggests that a genetic interaction with smoking might predict the pathobiology of smoking related disease.

    Hur påverkar fysisk aktivitet resultaten vid en elektroneurografisk undersökning: en litteraturstudie2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Electroneurographic studies are performed by a biomedical scientist. Electroneurography uses electricity to examine peripheral nerves. Research in this area is limited. Studies indicate that physical activity can affect the results of electroneurographic studies. However, today no protocol exists to register the amount of physical activity performed by patients.

    Aim: The aim of the study was to investigate how physical activity affects electroneurographic measurements, immediately after physical activity and after a period of regular physical activity.

    Method: Keywords in the area were determined based on the purpose. Databases used were Medline and CINAHL. Inclusion criteria were articles written in English that contained physical activity and electroneurography. Exclusion criteria were studies of participants with diseases which could affect the nerves.

    Results: The results show that physical activity can produce significant differences, immediately after physical activity and following a prolonged period of regular physical activity. However, the changes are small and cannot be misinterpreted as pathological.

    Discussion: The results of the studies are vastly different, indicating that the form and amount of physical activity may have significance.

    Conclusion: The result shows that physical activity affects the study. Suggestions for further research are to examine how participants with known nerve diseases are affected.

    Underdiagnosis of intestinal parasites in patients with diarrhea

    A compilation from the Swedish public health authority indicates that infections caused by Cryptosporidium spp. increased in Sweden from 47 cases in 2004 to 594 cases in 2016 and Giardia intestinalis causes around 1300 infections per year. The primary aim of this study was to investigate the prevalence of parasites in patients with diarrhea. Furthermore, the study investigated whether samples taken with E-swab could be analyzed with real-time polymerase chain reaction (PCR) for detection of Cryptosporidium spp., Dientamoeba fragilis, Entamoeba histolytica/dispar and G. intestinalis rather than Sodium acetate-acetic acid-formaline fixative (SAF-fixative). Prevalence of parasites in fecal samples was collected from 200 samples from patients with bacterial issue ordered. For evaluation of E-swab, 22 frozen, unfixed samples that were positive for intestinal parasites was used. Twelve positive E-swab samples was used as comparative positive controls. This was analyzed using real-time PCR. Bacteria was counted for 9.5% of the infections whilst parasites counted for 14% of the infections. The conclusion was that E-swab could replace SAF-fixative in the diagnosis of intestinal parasites and that there is that an underdiagnosis of intestinal parasites.

    Keywords: Cryptosporidium spp, Dientamoeba fragilis, Entamoeba histolytica, Entamoeba dispar, Giardia intestinalis, real-time PCR, E-swab, prevalence.

    Association between recurrent fracture risk and implementation of fracture liaison services in four Swedish hospitals: A cohort study2020In: Journal of Bone and Mineral Research, ISSN 0884-0431, E-ISSN 1523-4681, Vol. 35, no 7, p. 1216-1223Article in journal (Refereed)
    Abstract [en]

    Structured secondary preventions programs, called fracture liaison services (FLSs), increase the rate of evaluation with bone densitometry and use of osteoporosis medication after fracture. However, the evidence regarding the effect on the risk of recurrent fracture is insufficient. The aim of this study was to investigate if implementation of FLS was associated with reduced risk of recurrent fractures. In this retrospective cohort study, electronic health records during 2012 to 2017 were used to identify a total of 21,083 patients from four hospitals in Western Sweden, two with FLS (n = 15,449) and two without (n = 5634). All patients aged 50 years or older (mean age 73.9 [SD 12.4] years, 76% women) with a major osteoporotic index fracture (hip, clinical spine, humerus, radius, and pelvis) were included. The primary outcome was recurrent major osteoporotic fracture. All patients with an index fracture during the FLS period (n = 13,946) were compared with all patients in the period before FLS implementation (n = 7137) in an intention-to-treat analysis. Time periods corresponding to the FLS hospitals were used for the non-FLS hospitals. In the hospitals with FLSs, there were 1247 recurrent fractures during a median follow-up time of 2.2 years (range 0–6 years). In an unadjusted Cox model, the risk of recurrent fracture was 18% lower in the FLS period compared with the control period (hazard ratio = 0.82, 95% confidence interval [CI] 0.73–0.92, p = 0.001), corresponding to a 3-year number needed to screen of 61, and did not change after adjustment for clinical risk factors. In the hospitals without FLSs, no change in recurrent fracture rate was observed. Treatment decisions were made according to the Swedish treatment guidelines. In conclusion, implementation of FLS was associated with a reduced risk of recurrent fracture, indicating that FLSs should be included routinely at hospitals treating fracture patients.

    Serum amyloid A – A prime candidate for identification of neonatal sepsis2021In: Clinical Immunology, ISSN 1521-6616, E-ISSN 1521-7035, Vol. 229, article id 108787Article in journal (Refereed)
    Abstract [en]

    Neonatal sepsis is common, lethal, and hard to diagnose. In combination with clinical findings and blood culture, biomarkers are crucial to make the correct diagnose. A Swedish national inquiry indicated that neonatologists were not quite satisfied with the available biomarkers. We assessed the kinetics of 15 biomarkers simultaneously: ferritin, fibrinogen, granulocyte colony-stimulating factor (G-CSF), interferon (IFN)-γ, interleukin (IL)-1β, −6, −8, −10, macrophage inflammatory protein (MIP)-1β, procalcitonin, resistin, serum amyloid A (SAA), tumor necrosis factor (TNF)-α, tissue plasminogen activator-3 and visfatin. The goal was to observe how quickly they rise in response to infection, and for how long they remain elevated. From a neonatal intensive care unit, newborns ≥28 weeks gestational age were recruited. Sixty-eight newborns were recruited to the study group (SG), and fifty-one to the control group (CG). The study group subjects were divided into three subgroups depending on clinical findings: confirmed sepsis (CSG), suspected sepsis (SSG) and no sepsis. CSG and SSG were also merged into an entire sepsis group (ESG) for sub-analysis. Blood samples were collected at three time-points; 0 h, 12–24 h and 48–72 h, in order to mimic a “clinical setting”. At 0 h, visfatin was elevated in SSG compared to CG; G-CSF, IFN-γ, IL-1β, −8 and − 10 were elevated in SSG and ESG compared to CG, whereas IL-6 and SAA were elevated in all groups compared to CG. At 12–24 h, IL-8 was elevated in ESG compared to CG, visfatin was elevated in ESG and SSG compared to CG, and SAA was elevated in all three groups compared to CG. At 48–72 h, fibrinogen was elevated in ESG compared to CG, IFN-γ and IL-1β were elevated in SSG and ESG compared to CG, whereas IL-8 and SAA were elevated in all three groups compared to CG. A function of time-formula is introduced as a tool for theoretical prediction of biomarker levels at any time-point. We conclude that SAA has the most favorable kinetics regarding diagnosing neonatal sepsis, of the biomarkers studied. It is also readily available methodologically, making it a prime candidate for clinical use.

    Independent skewing of the T cell and NK cell compartments associated with cytomegalovirus infection suggests division of labor between innate and adaptive immunity.2014In: Age (Omaha), ISSN 0161-9152, E-ISSN 1574-4647, Vol. 36, no 2, p. 571-582Article in journal (Refereed)
    Abstract [en]

    Cytomegalovirus (CMV) infection induces profound changes in different subsets of the cellular immune system. We have previously identified an immune risk profile (IRP) where CMV-associated changes in the T cell compartment, defined as a CD4/CD8 ratio < 1, are associated with increased mortality in elderly people. Since natural killer (NK) cells have an important role in the defense against viral infections, we examined whether the expansion of CD8 + T cells seen in individuals with CD4/CD8 ratio < 1 is coupled to a parallel skewing of the NK cell compartment. A number of 151 subjects were examined with CMV serology and a flow cytometry panel for assessment of T cell and NK cell subsets. CMV-seropositive individuals had higher frequencies of CD57 + and NKG2C + NK cells and lower frequencies of NKG2A + NK cells, in line with a more differentiated NK cell compartment. Intriguingly, however, there was no correlation between CD4/CD8 ratio and NK cell repertoires among CMV-seropositive donors, despite the profound skewing of the T cell compartment in the group with CD4/CD8 ratio < 1. Conversely, donors with profound expansion of NK cells, defined as NKG2C + NK cells with high expression of CD57 and ILT-2, did not display more common changes in their T cell repertoire, suggesting that NK cell expansion is independent of the T cell-defined IRP. Altogether, these results indicate that the effect of CMV on CD8 T cells and NK cells is largely nonoverlapping and independent.

    Radiology departmental policy compliance with Swedish guidelines regarding post-contrast acute kidney injury for examinations with iodinated contrast media2021In: Radiography, ISSN 1078-8174, E-ISSN 1532-2831, Vol. 27, no 4, p. 1058-1063Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Guidelines concerning intravenous iodinated contrast media (CM) during computed tomography (CT) examinations are important to follow to minimize the risk for post-contrast acute kidney injury (PC-AKI). The purpose of this study was to investigate the radiology departmental policy compliance with Swedish guidelines concerning PC-AKI.

    METHODS: In February 2020, an electronic survey was distributed to the responsible radiographer at 41 radiology departments in all university hospitals and medium-sized hospitals in Sweden. The questions focused on routines around renal functional tests, individualized contrast administration and handling of patients with diabetes mellitus taking metformin.

    RESULTS: The response rate was 83%. Seventy-six percent (n = 26) of radiology departments calculated estimated glomerular filtration rate (eGFR) from serum creatinine prior to CM administration, but only 24% (n = 8) followed the recommendation to calculate eGFR from both serum creatinine and cystatin C. For acute/inpatients, 55% (n = 18) followed the recommendation that renal functional tests should be performed within 12 h before CM administration. For elective patients, 97% (n = 33) followed the recommendation to have eGFR newer than three months which is acceptable for patients with no history of disease that may have affected renal function. Approximately 80% of the radiology departments followed the recommendation that CM dose always should be individually adjusted to patient eGFR. Seventy-six percent (n = 26) followed the recommendation to continue with metformin at eGFR ≥ 45 ml/min.

    CONCLUSION: Compliance with the national guidelines was high regarding routines around renal functional tests, dose adjustment of CM and metformin discontinuation. Improvements can be made in using both cystatin C and serum creatinine for eGFR calculations as well as ensuring renal function tests within 12 h for acute/inpatients with acute disease that may affect renal function.

    IMPLICATIONS FOR PRACTICE: This study raises awareness of the importance of adhering to guidelines in healthcare. To have knowledge about the current level of compliance regarding PCI-AKI is important to maintain and develop effective clinical implementation of guidelines. The variation in practice seen in this study emphasizes the need of more effective implementation strategies to ensure adherence with best practice.

    Peri-radiographic guidelines for children with autism spectrum disorder: a nationwide survey in Sweden2017In: Child Care Health and Development, ISSN 0305-1862, E-ISSN 1365-2214, Vol. 43, no 1, p. 31-36Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: This study aimed to investigate the prevalence of guidelines and routines used nationwide when children with autism spectrum disorder (ASD) are taken care of and examined in a radiology department during a peri-radiographic process.

    METHOD: A nationwide survey was compiled and distributed to 94 radiology departments throughout Sweden, i.e. those performing more than 100 000 radiographic examinations annually. The survey was designed as a web questionnaire with seven questions on possible guidelines and/or routines for the departments when preparing and taking care of children with ASD in conjunction with a radiographic procedure. The data were scrutinized, using descriptive statistics.

    RESULTS: In total, 86 radiology departments responded to the survey (response rate 92%). Of those departments, 40 did not examine children with ASD. None of the departments included in the study had existing guidelines underpinning the routines when preparing and performing radiographic examinations for children diagnosed with ASD. A few departments (n = 8) would set aside more time for the procedure if it were known in advance that the child to be examined had been diagnosed with ASD. Also, some departments (n = 7) had radiographers who were more experienced in the care of children who would be appointed to perform examinations for children with ASD.

    CONCLUSION: It is suggested that guidelines should be developed in order to increase interaction in a supportive way and decrease anxiety during the peri-radiographic process with children with ASD.

    Are radiographers prepared to meet children with special needs, when seen for an examination?2017In: Acta Radiologica, ISSN 0284-1851, E-ISSN 1600-0455, Vol. 58, no 1 Suppl., p. 16-16Article in journal (Refereed)
    Abstract [en]

    Introduction: Anxiety is often experienced by children undergoing health care procedures, and children with autism spectrum disorders (ADS) experience more anxiety than typically developed children. A prerequisite for obtaining an optimum procedure is firstly based on the health care provider’s knowledge about children with ASD, but may also depend on the use of guidelines. Two previous national surveys showed, that none radiology or paediatric departments and a minority of anaesthesiology departments throughout Sweden use specific guidelines when seeing children with ASD. Following, the purpose was to develop guidelines to use when caring for and preparing children with ASD in those settings.

    Methods: A modified Delphi method was used, including19 experts identified from the two afore mentioned surveys. The questions considered in the process, proceeded from previous research and the results from the surveys. The experts’ responses regarding the importance of each item, were analysed and scrutinized between each round.

    Results: The Delphi process resulted in guidelines consisting of 15 items and a checklist with 16 aspects. The items cover the areas: planning and involving parents, features in the environment, use of time, communication, thehealth care professionals. The checklist covers the child’spattern of communication, anxiety, sensory stimuli, special interests and likes/dislikes.

    Conclusions: To obtain an optimum caring encounter when a child with ASD is seen in the preoperative and radiology setting, a meticulous planning is important and the environment should be adjusted for the needs of the child. To accomplish this, guidelines need to be in place and be followed.

    Bronchial responsiveness to dry air hyperventilation in smokers may predict decline in airway status using indirect methods2013In: Lung, ISSN 0341-2040, E-ISSN 1432-1750, Vol. 191, no 2, p. 183-190Article in journal (Refereed)
    Abstract [en]

    Background

    Disabling respiratory symptoms and rapid decline of lung function may occur in susceptible tobacco smokers. Bronchial hyperresponsiveness (BHR) elicited by direct challenge methods predicts worse lung function outcomes. The aim of this study was to evaluate whether BHR to isocapnic hyperventilation of dry air (IHDA) was associated with rapid deterioration in airway status and respiratory symptoms.

    Methods

    One hundred twenty-eight smokers and 26 age- and sex-matched healthy individuals with no history of smoking were investigated. All subjects completed a questionnaire. Spirometry and impulse oscillometry (IOS) measurements were recorded before and after 4 min of IHDA. The tests were repeated after 3 years in 102 smokers and 11 controls.

    Results

    Eighty-five smokers (66 %) responded to the challenge with a ≥2.4-Hz increase in resonant frequency (F res), the cutoff limit defining BHR, as recorded by IOS. They had higher F res at baseline compared to nonresponding smokers [12.8 ± 3.2 vs. 11.5 ± 3.4 Hz (p < 0.05)] and lower FEV1 [83 ± 13 vs. 89 ± 13 % predicted (p < 0.05)]. Multivariable logistic regression analysis indicated that wheezing (odds ratio = 3.7, p < 0.01) and coughing (odds ratio = 8.1, p < 0.05) were significantly associated with hyperresponsiveness. An increase in F res was recorded after 3 years in responding smokers but not in nonresponders or controls. The difference remained when subjects with COPD were excluded.

    Conclusions

    The proportion of hyperresponsive smokers was unexpectedly high and there was a close association between wheezing and coughing and BHR. Only BHR could discriminate smokers with rapid deterioration of airway status from others.

    Effects of a single exercise workout on memory and learning functions in young adults—A systematic review2021In: Translational Sports Medicine, ISSN 2573-8488, Vol. 4, no 1, p. 115-127Article in journal (Refereed)
    Abstract [en]

    Abstract

    The purpose of this systematic review was to evaluate the current literature examining the acute effects of a single exercise workout on learning and memory functions in young adults.

    Methods

    The review was conducted in alignment with the PRISMA guidelines. Studies were included if they were indexed in PubMed, published between 2009 and 2019, used an experimental study design and conducted on young human adults. The MeSH terms “exercise,” “learning,” and “young adults” were used together with the filters Publication dates—10 years; Human Species; and Article types—Clinical Trial.

    Results

    Thirteen studies met the inclusion criteria and were evaluated. The types of exercise stimulus that were used was walking, running, or bicycling. Several different test instruments were used such as Rey Auditory Verbal Learning Test, Trail Making Test A and B, and Stroop Color Word Test. Exercise for two minutes to one hour at moderate to high intensity had a favorable effect on learning and memory functions in the selected studies.

    Conclusions

    This systematic review shows that aerobic, physical exercise before encoding improves learning and memory functions in young adults.

    Overweight and obesity impair left ventricular systolic function as measured by left ventricular ejection fraction and global longitudinal strain2018In: Cardiovascular Diabetology, E-ISSN 1475-2840, Vol. 17, no 1, article id 113Article in journal (Refereed)
    Abstract [en]

    Aims

    Obesity is associated with type 2 diabetes mellitus, left ventricular diastolic dysfunction and heart failure but it is unclear to which extent it is related to left ventricular systolic dysfunction. The aim of the study was to explore the effects of overweight and obesity on left ventricular systolic function in patients with type 2 diabetes mellitus and a control group of non-diabetic persons.

    Methods

    We prospectively investigated 384 patients with type 2 diabetes mellitus, and 184 controls who participated in the CARDIPP and CAREFUL studies. The participants were grouped according to body mass index (normal weight < 25 kg/m2, overweight 25–29 kg/m2, and obesity ≥ 30 kg/m2). Echocardiography was performed at the beginning of the study and after 4-years in the patient group.

    Results

    Univariable and multivariable regression analysis revealed that variations in left ventricular ejection fraction, global longitudinal strain, left ventricular mass and diastolic function expressed as E/é (the ratio between early diastolic mitral flow and annular motion velocities) all are related to body mass index. The mean and standard deviation of left ventricular ejection fraction and global longitudinal strain values were 57% (8%) vs. − 18.6% (2.3%) for normal weight patients, 53% (8%) vs. − 17.5% (2.3%) for overweight, and 49% (9%) vs. − 16.2% (3.0%) for obese (p < 0.05 vs. p < 0.05). Corresponding results in the control group were 58% (6%) vs. − 22.3% (3.0%), 55% (7%) vs. − 20.8% (3.1%) and 54% (8%) − 19.6% (4.0%) (p < 0.05 vs. p < 0.05). Patients who gained weight from baseline to follow-up changed left ventricular ejection fraction (median and interquartile range) by − 1.0 (9.0) % (n = 187) and patients who lost weight changed left ventricular ejection fraction by 1.0 (10.0) % (n = 179) (p < 0.05).

    Conclusion

    Overweight and obesity impair left ventricular ejection fraction and global longitudinal strain in both patients with type 2 diabetes mellitus and non-diabetic persons.

    Mind body exercise improves cognitive function more than aerobic- and resistance exercise in healthy adults aged 55 years and older: an umbrella review2023In: European Review of Aging and Physical Activity, ISSN 1813-7253, E-ISSN 1861-6909, Vol. 20, no 1, article id 15Article, review/survey (Refereed)
    Abstract [en]

    Exercise is often cited as a major factor contributing to improved cognitive functioning. As a result, the relationship between exercise and cognition has received much attention in scholarly literature. Systematic reviews and meta-analyses present varying and sometimes conflicting results about the extent to which exercise can influence cognition. The aim of this umbrella review was to summarize the effects of physical exercise on cognitive functions (global cognition, executive function, memory, attention, or processing speed) in healthy adults & GE; 55 years of age.Methods An umbrella review of systematic reviews with meta-analyses investigating the effect of exercise on cognition was performed. Databases (CINAHL, Cochrane Library, MEDLINE, PsycInfo, Scopus, and Web of Science) were searched from inception until June 2023 for reviews of randomized or non-randomised controlled trials. Full-text articles meeting the inclusion criteria were reviewed and methodological quality assessed. Overlap within included reviews was assessed using the corrected covered area method (CCA). A random effects model was used to calculate overall pooled effect size with sub-analyses for specific cognitive domains, exercise type and timing of exercise.Results Database searches identified 9227 reviews. A total of 20 met the inclusion criteria. They were based on 332 original primary studies. Overall quality of the reviews was considered moderate with most meeting 8 or more of the 16 AMSTAR 2 categories. Overall pooled effects indicated that exercise in general has a small positive effect on cognition (d = 0.22; SE = 0.04; p < 0.01). Mind-body exercise had the greatest effect with a pooled effect size of (d = 0.48; SE = 0.06; p < 0.001). Exercise had a moderate positive effect on global cognition (d = 0.43; SE = 0,11; p < 0,001) and a small positive effect on executive function, memory, attention, and processing speed. Chronic exercise was more effective than acute exercise. Variation across studies due to heterogeneity was considered very high.Conclusions Mind-body exercise has moderate positive effects on the cognitive function of people aged 55 or older. To promote healthy aging, mind-body exercise should be used over a prolonged period to complement other types of exercise. Results of this review should be used to inform the development of guidelines to promote healthy aging.

    Standardised assessment of functioning in ADHD: consensus on the ICF Core Sets for ADHD2018In: European Child and Adolescent Psychiatry, ISSN 1018-8827, E-ISSN 1435-165X, Vol. 27, no 10, p. 1261-1281Article in journal (Refereed)
    Abstract [en]

    Attention-deficit/hyperactivity disorder (ADHD) is associated with significant impairments in social, educational, and occupational functioning, as well as specific strengths. Currently, there is no internationally accepted standard to assess the functioning of individuals with ADHD. WHO’s International Classification of Functioning, Disability and Health—child and youth version (ICF) can serve as a conceptual basis for such a standard. The objective of this study is to develop a comprehensive, a common brief, and three age-appropriate brief ICF Core Sets for ADHD. Using a standardised methodology, four international preparatory studies generated 132 second-level ICF candidate categories that served as the basis for developing ADHD Core Sets. Using these categories and following an iterative consensus process, 20 ADHD experts from nine professional disciplines and representing all six WHO regions selected the most relevant categories to constitute the ADHD Core Sets. The consensus process resulted in 72 second-level ICF categories forming the comprehensive ICF Core Set—these represented 8 body functions, 35 activities and participation, and 29 environmental categories. A Common Brief Core Set that included 38 categories was also defined. Age-specific brief Core Sets included a 47 category preschool version for 0–5 years old, a 55 category school-age version for 6–16 years old, and a 52 category version for older adolescents and adults 17 years old and above. The ICF Core Sets for ADHD mark a milestone toward an internationally standardised functional assessment of ADHD across the lifespan, and across educational, administrative, clinical, and research settings. © 2018 The Author(s)

    The importance of psychological and physical stressors on diabetes-related immunity in a young population – an interdisciplinary approach2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background: The prevalence of immunological disorders such as type 1 diabetes (T1D) is increasingly common amongst children, adolescents and young adults. There is also an increase in psychosomatic symptoms (depression, insomnia, anxiety, headaches and fatigue etc.) as well as a decrease in physical activity amongst young people, affecting the well-being and overall health of our younger population. It is therefore important to study the effects of psychological and physical stressors on the immune system, to evaluate their impact on juvenile health.

    Aim: This thesis explores the impact of psychological and physical stressors on the cellular immune system with special focus on diabetes-related immunity in a young population, using an interdisciplinary approach.

    Method: When exploring the impact of psychological and physical stressors such as psychological stress due to exposure to psychological stressful experiences or degree of physical activity/training on the cellular immune system in children, adolescents and young women, peripheral blood mononuclear cells (PBMC) were stimulated with antigens (tetanus toxoid (TT) and β-lactoglobulin (βLG)) as well as diabetes-related autoantigens (insulin, heat shock protein 60 (HSP60), tyrosine phosphatase-2 (IA-2) and glutamic acid decarboxylase 65 (GAD65)) and secreted cytokines and chemokines were measured by multiplex fluorochrome technique (Luminex). Populations of Thelper (Th) cells (CD4+), T-cytotoxic (Tc) cells (CD8+), B cells (CD19+), Natural Killer (NK) cells (CD56+CD16+) as well as regulatory T (Treg) cells (CD4+CD25+FoxP3+CD127-), and their expression of CD39 and CD45RA were studied by flow cytometry. Diabetes-related parameters (glucose, C-peptide,proinsulin, pancreatic polypeptide and peptide YY) were measured to studyβ-cell activity and appetite regulation and cortisol was used as a biological marker for psychological and physical stress.

    Results: Children in families exposed to psychological stress showed an imbalanced cellular immune response as well as an increased immune response towards diabetes-related autoantigens. Also, previous exposure to psychological stress as well as current exposure to psychological stress in young women showed an increased immune response towards diabetes-related autoantigens. Further, previous exposure to psychological stress in young women showed increased numbers of circulating CD56+CD16+ NK cells as wellas decreased numbers of circulating CD4+CD25+FoxP3+CD127- Treg cells. High physical activity in children showed decreased spontaneous immune response as well as a decreased immune response towards diabetes-related autoantigens, while low physical activity in children showed an increased immune response towards diabetes-related autoantigens. Further, endurance training in adolescents, especially in adolescent males and young adolescents, showed an increased immune response towards the diabetes-related autoantigen IA-2.

    Conclusion: It is evident that psychological and physical stressors such as exposure to psychological stress and degree of physical activity/training impact the cellular immune system. Experiences associated with psychological stress seem to have a negative effect on the cellular immune system in a young population, causing an imbalance in the immune system that could possibly induce diabetes-related immunity. High physical activity in children seems to have a protective effect against diabetes-related immunity. In contrast, low physical activity in children and endurance training in adolescents seems to induce diabetes-related immunity. It is very likely that psychological stressful experiences, low physical activity and intense training such as endurance training all play important roles in the immunological process leading to the development of type 1 diabetes.

    Psychological Stress in Children May Alter the Immune Response2014In: Journal of Immunology, ISSN 0022-1767, E-ISSN 1550-6606, Vol. 192, no 5, p. 2071-2081Article in journal (Refereed)
    Abstract [en]

    Psychological stress is a public health issue even in children and has been associated with a number of immunological diseases. The aim of this study was to examine the relationship between psychological stress and immune response in healthy children, with special focus on autoimmunity. In this study, psychological stress was based on a composite measure of stress in the family across the domains: 1) serious life events, 2) parenting stress, 3) lack of social support, and 4) parental worries. PBMCs, collected from 5-y-old high-stressed children (n = 26) and from 5-y-old children without high stress within the family (n = 52), from the All Babies In Southeast Sweden cohort, were stimulated with Ags (tetanus toxoid and β-lactoglobulin) and diabetes-related autoantigens (glutamic acid decarboxylase 65, insulin, heat shock protein 60, and tyrosine phosphatase). Immune markers (cytokines and chemokines), clinical parameters (C-peptide, proinsulin, glucose), and cortisol, as an indicator of stress, were analyzed. Children from families with high psychological stress showed a low spontaneous immune activity (IL-5, IL-10, IL-13, IL-17, CCL2, CCL3, and CXCL10; p < 0.01) but an increased immune response to tetanus toxoid, β-lactoglobulin, and the autoantigens glutamic acid decarboxylase 65, heat shock protein 60, and tyrosine phosphatase (IL-5, IL-6, IL-10, IL-13, IL-17, IFN-γ, TNF-α, CCL2, CCL3, and CXCL10; p < 0.05). Children within the high-stress group showed high level of cortisol, but low level of C-peptide, compared with the control group (p < 0.05). This supports the hypothesis that psychological stress may contribute to an imbalance in the immune response but also to a pathological effect on the insulin-producing β cells.

    High physical activity in young children suggests positive effects by altering autoantigen-induced immune activity2016In: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 26, no 4, p. 441-450Article in journal (Refereed)
    Abstract [en]

    Physical activity in children is associated with several positive health outcomes such as decreased cardiovascular risk factors, improved lung function, enhanced motor skill development, healthier body composition, and also improved defense against inflammatory diseases. We examined how high physical activity vs a sedentary lifestyle in young children influences the immune response with focus on autoimmunity. Peripheral blood mononuclear cells, collected from 55 5-year-old children with either high physical activity (n = 14), average physical activity (n = 27), or low physical activity (n  = 14), from the All Babies In Southeast Sweden (ABIS) cohort, were stimulated with antigens (tetanus toxoid and beta-lactoglobulin) and autoantigens (GAD65, insulin, HSP60, and IA-2). Immune markers (cytokines and chemokines), C-peptide and proinsulin were analyzed. Children with high physical activity showed decreased immune activity toward the autoantigens GAD65 (IL-5, P < 0.05), HSP60 and IA-2 (IL-10, P < 0.05) and also low spontaneous pro-inflammatory immune activity (IL-6, IL-13, IFN-γ, TNF-α, and CCL2 (P  < 0.05)) compared with children with an average or low physical activity. High physical activity in young children seems to have positive effects on the immune system by altering autoantigen-induced immune activity.

    Exploring vitamin D and steroid hormone receptors – from healthy elderly to prostate cancer cells2022Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The genetic background together with environmental factors and lifestyle are key contributors to the health of an individual. Genetic background is inherited and irreversible unless mutations occur. However, lifestyle habits (i.e., diet, stress, physical activity, smoking, and alcohol consumption) are modifiable factors that contribute to health or disease by affecting methylation of DNA, which regulates transcription of genes.

    One of the most relevant lifestyle habits for health is maintaining adequate vitamin D levels in the body as vitamin D promotes calcium and phosphate absorption, supports the nervous and immune system function, and protects bone and muscle structure. Extreme low levels of vitamin D, vitamin D deficiency, has become a global public health concern, especially in the elderly population as vitamin D deficiency can lead to several health problems such as bone fracture, decreased muscle strength, cardiovascular and autoimmune diseases, depression, and breast, pancreatic, and prostate cancer.

    Prostate cancer is an uncontrolled growth of cells within the prostate gland in the male reproductive system. Human prostate carcinomas are sensitive to androgens, and hormonal ablation therapy gives a temporary remission, followed by a relapse to an androgen-insensitive state. This indicates that steroid hormones, especially androgens, play a significant role in human prostatic carcinogenesis. The molecular effect of vitamin D as a steroid hormone and which steroid hormone receptor (SHR) mediates this effect are not fully understood.

    This research project aims to increase our knowledge about SHRs, primarily the vitamin D receptors, in both health and disease, focusing on genomic, epigenomic, and transcriptomic perspectives in healthy elderly individuals and prostate cancer cells.

    The results from the studies in this thesis could help us understand the importance of a healthy lifestyle, which includes vitamin D for health, where we found specific methylation markers involved in the down-regulation of cancer pathways that are associated with high physical activity and vitamin D supplementation. We have further confirmed that SHRs rarely work in isolation but rather as a crosstalk at the genomic level to regulate their transcription. Hopefully, this will help clarify the modulation of transcriptional responses in SHRs and explain the development of steroid hormone-dependent cancers such as prostate cancer. Last, but not least, we revealed that genetic and transcriptional markers are associated with the putative vitamin D receptor the protein disulfide isomerase family A member 3 (PDIA3). The genetic markers were detected in a healthy elderly population under vitamin D supplementation. The transcriptional markers, PDIA3, and a novel discovered isoform of PDIA3 (PDIA3N) were related to the androgen and cancer stage of prostate cancer cells and therefore are proposed as candidate markers for clinical diagnosis of prostate cancer.

    Altogether, these findings support the relevance of studying vitamin D and steroid hormone receptors, especially the PDIA3 receptor, to understand some of the factors related to healthy aging and the etiology and progression of prostate cancer.

    Differential expression of protein disulfide-isomerase A3 isoforms, PDIA3 and PDIA3N, in human prostate cancer cell lines representing different stages of prostate cancer2021In: Molecular Biology Reports, ISSN 0301-4851, E-ISSN 1573-4978, Vol. 48, p. 2429-2436Article in journal (Refereed)
    Abstract [en]

    Prostate cancer (PCa) is a highly heterogeneous and unpredictable progressive disease. Sensitivity of PCa cells to androgens play a central role in tumor aggressiveness but biomarkers with high sensitivity and specificity that follow the progression of the disease has not yet been verified. The vitamin D endocrine system and its receptors, the Vitamin D Receptor (VDR) and the Protein Disulfide-Isomerase A3 (PDIA3), are related to anti-tumoral effects as well as carcinogenesis and have therefore been suggested as potential candidates for the prevention and therapy of several cancer forms, including PCa. In this study, we evaluated the mRNA expression of VDR and PDIA3 involved in vitamin D signaling in cell lines representing different stages of PCa (PNT2, P4E6, LNCaP, DU145 and PC3). This study further aimed to evaluate vitamin D receptors and their isoforms as potential markers for clinical diagnosis of PCa. A novel transcript isoform of PDIA3 (PDIA3N) was identified and found to be expressed in all PCa cell lines analyzed. Androgen-independent cell lines showed a higher mRNA expression ratio between PDIA3N/PDIA3 contrary to androgen-dependent cell lines that showed a lower mRNA expression ratio between PDIA3N/PDIA3. The structure of PDIA3N differed from PDIA3. PDIA3N was found to be a N-truncated isoform of PDIA3 and differences in protein structure suggests an altered protein function i.e. cell location, thioredoxin activity and affinity for 1,25(OH)2D3. Collectively, PDIA3 transcript isoforms, the ratio between PDIA3N/PDIA3 and especially PDIA3N, are proposed as candidate markers for future studies with different stages of PCa progression.

    Cis-regulatory elements in conserved non-coding sequences of nuclear receptor genes indicate for crosstalk between endocrine systems2021In: Open Medicine (Poland), ISSN 2391-5463, Vol. 16, no 1, p. 640-650Article in journal (Refereed)
    Abstract [en]

    Nuclear receptors (NRs) are ligand-activated transcription factors that regulate gene expression when bound to specific DNA sequences. Crosstalk between steroid NR systems has been studied for understanding the development of hormone-driven cancers but not to an extent at a genetic level. This study aimed to investigate crosstalk between steroid NRs in conserved intron and exon sequences, with a focus on steroid NRs involved in prostate cancer etiology. For this purpose, we evaluated conserved intron and exon sequences among all 49 members of the NR Superfamily (NRS) and their relevance as regulatory sequences and NR-binding sequences. Sequence conservation was found to be higher in the first intron (35%), when compared with downstream introns. Seventy-nine percent of the conserved regions in the NRS contained putative transcription factor binding sites (TFBS) and a large fraction of these sequences contained splicing sites (SS). Analysis of transcription factors binding to putative intronic and exonic TFBS revealed that 5 and 16%, respectively, were NRs. The present study suggests crosstalk between steroid NRs, e.g., vitamin D, estrogen, progesterone, and retinoic acid endocrine systems, through cis-regulatory elements in conserved sequences of introns and exons. This investigation gives evidence for crosstalk between steroid hormones and contributes to novel targets for steroid NR regulation.

    Characterization of methylation patterns associated with lifestyle factors and vitamin D supplementation in a healthy elderly cohort from Southwest Sweden2022In: Scientific Reports, E-ISSN 2045-2322, Vol. 12, no 1, article id 12670Article in journal (Refereed)
    Abstract [en]

    Numerous studies have shown that lifestyle factors, such as regular physical activity and vitamin D intake, may remarkably improve overall health and mental wellbeing. This is especially important in older adults whose vitamin D deficiency occurs with a high prevalence. This study aimed to examine the influence of lifestyle and vitamin D on global DNA methylation patterns in an elderly cohort in Southwest of Sweden. We also sought to examine the methylation levels of specific genes involved in vitamin D's molecular and metabolic activated pathways. We performed a genome wide methylation analysis, using Illumina Infinium DNA Methylation EPIC 850kBeadChip array, on 277 healthy individuals from Southwest Sweden at the age of 70–95. The study participants also answered queries on lifestyle, vitamin intake, heart medication, and estimated health. Vitamin D intake did not in general affect methylation patterns, which is in concert with other studies. However, when comparing the group of individuals taking vitamin supplements, including vitamin D, with those not taking supplements, a difference in methylation in the solute carrier family 25 (SCL25A24) gene was found. This confirms a previous finding, where changes in expression of SLC25A24 were associated with vitamin D treatment in human monocytes. The combination of vitamin D intake and high physical activity increased methylation of genes linked to regulation of vitamin D receptor pathway, the Wnt pathway and general cancer processes. To our knowledge, this is the first study detecting epigenetic markers associated with the combined effects of vitamin D supplementation and high physical activity. These results deserve to be further investigated in an extended, interventional study cohort, where also the levels of 25(OH)D3 can be monitored.

    Genomic Profiling of Stage II Colorectal Cancer Identifies Candidate Genes Associated with Recurrence-Free Survival, Tumor Location, and Differentiation Grade.2020In: Oncology, ISSN 0030-2414, E-ISSN 1423-0232, Vol. 98, no 8, p. 575-582Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Identification of high-risk stage II colorectal cancer (CRC) patients, potential candidates for adjuvant chemotherapy, is challenging. Current clinical guidelines rely mainly on histopathological markers with relatively weak prognostic value. This motivates further search for prognostic markers.

    METHODS: This explorative study aimed to identify potential candidate gene mutations to facilitate differentiation between subgroups of patients with CRC stage II. Panel-based massive parallel sequencing was used to genetically characterize tumor tissues from 85 patients radically operated for CRC stage II, of which 12 developed recurrent cancer during follow-up. Genetic data was compared between patients with or without cancer recurrence, between tumors located in colon and in rectum, and for association with tumor differentiation grade.

    RESULTS: Genetic variation in ATM, C11ORF65 was associated with recurrence-free survival. Previous reports regarding the association between BRAF mutation and a higher age at diagnosis, and tumor location in colon were confirmed. APC, BRAF, or KRAS mutation was associated with tumor differentiation grade. Multiple correspondence analyses revealed no obvious clustering of patients with the studied clinical characteristics, indicating that the genetic signatures observed here were unique for each individual.

    CONCLUSIONS: Taken together, we have demonstrated the utility of panel-based massive parallel sequencing to explore the pathogenesis of CRC stage II. We have identified promising candidate gene mutations associated with cancer recurrence, tumor location, and differentiation grade in patients with CRC stage II, which merit further investigation.

    Common 4977 bp deletion and novel alterations in mitochondrial DNA in Vietnamese patients with breast cancer2015In: SpringerPlus, E-ISSN 2193-1801, Vol. 4, p. 1-7, article id 58Article in journal (Refereed)
    Abstract [en]

    Mitochondrial DNA (mtDNA) has been proposed to be involved in carcinogenesis and ageing. The mtDNA 4977 bp deletion is one of the most frequently observed mtDNA mutations in human tissues and may play a role in breast cancer (BC). The aim of this study was to investigate the frequency of mtDNA 4977 bp deletion in BC tissue and its association with clinical factors.

    We determined the presence of the 4977 bp common deletion in cancer and normal paired tissue samples from 106 Vietnamese patients with BC by sequencing PCR products.

    The mtDNA 4977 bp deletion was significantly more frequent in normal tissue in comparison with paired cancer tissue. Moreover, the incidence of the 4977 bp deletion in BC tissue was significantly higher in patients with estrogen receptor (ER) positive as compared with ER negative BC tissue. Preliminary results showed, in cancerous tissue, a significantly higher incidence of novel deletions in the group of patients with lymph node metastasis in comparison with the patients with no lymph node metastasis.

    We have found 4977 bp deletion in mtDNA to be a common event in BC and with special reference to ER positive BC. In addition, the novel deletions were shown to be related to lymph node metastasis. Our finding may provide complementary information in prediction of clinical outcome including metastasis, recurrence and survival of patients with BC.

    Genetic polymorphism patterns suggest a genetic driven inflammatory response as pathogenesis in appendicitis2020In: International Journal of Colorectal Disease, ISSN 0179-1958, E-ISSN 1432-1262, Vol. 35, p. 277-284Article in journal (Refereed)
    Abstract [en]

    PURPOSE: The pathogenesis of appendicitis is not well understood. Environmental factors are regarded most important, but epidemiologic findings suggest a role of inflammatory and genetic mechanisms. This study determines the association of single nucleotide polymorphisms (SNPs) of inflammatory genes with appendicitis.

    METHODS: As part of a larger prospective study on the diagnostic value of inflammatory variables in appendicitis, the genotype frequency of 28 polymorphisms in 26 inflammatory response genes from the appendicitis and control patients was analyzed in blood samples from 343 patients, 100 with appendicitis, and 243 with non-specific abdominal pain, using TaqMan SNP genotyping assays.

    RESULTS: Associations with appendicitis were found for SNPs IL-13 rs1800925 with odds ratio (OR) 6.02 (95% CI 1.52-23.78) for T/T versus C/C + T/T, for IL-17 rs2275913 with OR 2.38 (CI 1.24-4.57) for A/A vs G/G + GA, for CCL22 rs223888 with OR 0.12 (0.02-0.90), and for A/A vs G/G + GA. Signs of effect modification of age for the association with appendicitis were found for IL-13 rs1800925 and CTLA4 rs3087243. Stratified analysis showed difference in association with severity of disease for IL-17 rs2275913 and CD44 rs187115.

    CONCLUSIONS: The association of gene variants on risk of appendicitis and its severity suggest an etiologic role of genetically regulated inflammatory response. This may have implications for understanding the prognosis of untreated appendicitis as a possible self-limiting disorder and for understanding the inverse association of appendicitis with ulcerative colitis.

    Genetic variants of the IL2 gene related to risk and survival in patients with colorectal cancer2019In: Anticancer Research, ISSN 0250-7005, E-ISSN 1791-7530, Vol. 39, no 9, p. 4933-4940Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Interleukin 2 (IL2) is a significant factor activating T-cell-mediated immune response by stimulation of natural killer cells, T-cells and in development of regulatory T (Treg) cells. Recent studies have that IL2 participates in cancer development by modifying the local immune response. Based on the suggested role of the single nucleotide polymorphisms (SNPs) rs2069762, rs6822844 and rs11938795 of IL2 in the pathogenesis of certain diseases, the relationship of these SNPs with clinicopathological variables and their possible implication for prognosis and disease outcome were evaluated in a cohort of Swedish patients with colorectal cancer (CRC).

    MATERIALS AND METHODS: TaqMan SNP genotype assays based on polymerase chain reaction were used for analysis of the IL2 SNPs in 467 patients with CRC and 467 healthy controls. Expression analysis of IL2 in plasma and CRC tissue was also performed.

    RESULTS: The allelic variants T in rs11938795 and G in rs6822844 were significantly associated with a higher risk of CRC. Kaplan-Meier analysis showed that cancer-specific survival was worse for individuals with C allele for rs2069762 with stage II CRC and with T allele for rs6822844 with stage III CRC.

    CONCLUSION: SNPs rs2069762, rs6822844 and rs11938795 of the IL2 gene may be helpful as prognostic biomarkers in the follow-up and management of the patients.

    Effects of diabetes type 2 and metformin treatment in Swedish patients with colorectal cancer2022In: World Journal of Gastroenterology, ISSN 1007-9327, E-ISSN 2219-2840, Vol. 28, no 19, p. 2148-2151Article in journal (Refereed)
    Abstract [en]

    The association between type 2 diabetes mellitus (DM) and colorectal cancer (CRC) has been thoroughly investigated and reports have demonstrated that the risk of CRC is increased in DM patients. The association between DM and the survival of patients with CRC is controversial. Evidence suggests that metformin with its anti-inflammatory effects is a protective factor against the development of CRC among DM patients and that metformin therapy is associated with a better prognosis in patients with DM. In our cohort, we did not find any associations between the presence of DM or metformin and cancer specific survival or any relation to plasma levels of a panel of 40 inflammatory factors and irisin. On the other hand, we identified that the insulin-like growth factor binding protein 7 single nucleotide polymorphism rs2041437 was associated with DM in CRC patients. The dominance of the T bearing genotypes in patients with DM was statistically significant (P = 0.038), with an odds ratio of 1.66 (95% confidence interval: 1.03-2.69).

    Protein expression and gene polymorphism of CXCL10 in patients with colorectal cancer2014In: Biomedical Reports, ISSN 2049-9442, Vol. 2, no 3, p. 340-343Article in journal (Refereed)
    Abstract [en]

    Chemokines (chemotactic cytokines) promote leukocyte attraction to sites of inflammation and cancer. Certain chemokines promote and regulate neoplastic progression, including metastasis and angiogenesis. One such chemokine, CXCL10, was found to be expressed in colorectal cancer (CRC) tissue. To gain insight into the prognostic significance of CXCL10, we investigated whether the levels of this chemokine were altered in the colorectal tissue or plasma of CRC patients. Using Luminex technology for protein analyses, we observed a significantly higher CXCL10 protein level in cancer tissue compared to that in paired normal tissue. Moreover, significantly higher plasma levels of CXCL10 were detected in patients compared to those in control subjects and the plasma levels of CXCL10 in disseminated disease were found to be significantly higher compared to those in localized disease. The single‑nucleotide polymorphism rs8878, which has been described in exon 4 in the 3'‑untranslated region of the CXCL10 gene, was investigated using a TaqMan system. There were significant differences in genotype distribution and allelic frequencies between CRC patients and control subjects. In conclusion, altered CXCL10 protein concentrations in CRC tissues or plasma and the rs8878 genotype variant of CXCL10 may contribute to the prediction of clinical outcome.

    Gene polymorphism in DNA repair genes XRCC1 and XRCC6 and association with colorectal cancer in Swedish patients2016In: Acta Pathologica, Microbiologica et Immunologica Scandinavica (APMIS), ISSN 0903-4641, E-ISSN 1600-0463, Vol. 124, no 9, p. 736-740Article in journal (Refereed)
    Abstract [en]

    The DNA repair genes XRCC1 and XRCC6 have been proposed to participate in the pathological process of cancer by modulating the DNA repair capacity. This study evaluated the susceptibility of the single-nucleotide polymorphisms (SNPs) XRCC1 (rs25487, G > A) and XRCC6 (rs2267437, C > G) to colorectal cancer (CRC) and their association with clinical parameters in Swedish patients with CRC. Using the TaqMan system, these SNPs were screened in 452 patients and 464 controls. No significant difference in genotype distribution was found between the patients and controls, or any significant association with cancer-specific or disease-free survival in patients. However, we showed that the carriers of allele A in XRCC1 (rs25487, G > A) were connected with a higher risk of disseminated CRC (Odds Ratio = 1.64; 95% Confidence Interval = 1.12–2.41, p = 0.012).
