1.	Teede, Helena J, et al. (författare) Recommendations from the 2023 International Evidence-based Guideline for the Assessment and Management of Polycystic Ovary Syndrome. 2023 Ingår i: Fertility and sterility. - 1556-5653. ; 120:4, s. 767-793 Tidskriftsartikel (refereegranskat)abstract What is the recommended assessment and management of those with polycystic ovary syndrome (PCOS), based on the best available evidence, clinical expertise, and consumer preference?International evidence-based guidelines address prioritized questions and outcomes and include 254 recommendations and practice points, to promote consistent, evidence-based care and improve the experience and health outcomes in PCOS.The 2018 International PCOS Guideline was independently evaluated as high quality and integrated multidisciplinary and consumer perspectives from six continents; it is now used in 196 countries and is widely cited. It was based on best available, but generally very low to low quality, evidence. It applied robust methodological processes and addressed shared priorities. The guideline transitioned from consensus based to evidence-based diagnostic criteria and enhanced accuracy of diagnosis, whilst promoting consistency of care. However, diagnosis is still delayed, the needs of those with PCOS are not being adequately met, evidence quality was low and evidence-practice gaps persist.The 2023 International Evidence-based Guideline update reengaged the 2018 network across professional societies and consumer organizations with multidisciplinary experts and women with PCOS directly involved at all stages. Extensive evidence synthesis was completed. Appraisal of Guidelines for Research and Evaluation-II (AGREEII)-compliant processes were followed. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework was applied across evidence quality, feasibility, acceptability, cost, implementation and ultimately recommendation strength and diversity and inclusion were considered throughout.This summary should be read in conjunction with the full Guideline for detailed participants and methods. Governance included a six-continent international advisory and management committee, five guideline development groups, and paediatric, consumer, and translation committees. Extensive consumer engagement and guideline experts informed the update scope and priorities. Engaged international society-nominated panels included paediatrics, endocrinology, gynaecology, primary care, reproductive endocrinology, obstetrics, psychiatry, psychology, dietetics, exercise physiology, obesity care, public health and other experts, alongside consumers, project management, evidence synthesis, statisticians and translation experts. Thirty-nine professional and consumer organizations covering 71 countries engaged in the process. Twenty meetings and five face-to-face forums over 12 months addressed 58 prioritized clinical questions involving 52 systematic and 3 narrative reviews. Evidence-based recommendations were developed and approved via consensus across five guideline panels, modified based on international feedback and peer review, independently reviewed for methodological rigour, and approved by the Australian Government National Health and Medical Research Council (NHMRC).The evidence in the assessment and management of PCOS has generally improved in the past five years, but remains of low to moderate quality. The technical evidence report and analyses (∼6000 pages) underpins 77 evidence-based and 54 consensus recommendations, with 123 practice points. Key updates include: i) further refinement of individual diagnostic criteria, a simplified diagnostic algorithm and inclusion of anti-Müllerian hormone (AMH) levels as an alternative to ultrasound in adults only; ii) strengthening recognition of broader features of PCOS including metabolic risk factors, cardiovascular disease, sleep apnea, very high prevalence of psychological features, and high risk status for adverse outcomes during pregnancy; iii) emphasizing the poorly recognized, diverse burden of disease and the need for greater healthcare professional education, evidence-based patient information, improved models of care and shared decision making to improve patient experience, alongside greater research; iv) maintained emphasis on healthy lifestyle, emotional wellbeing and quality of life, with awareness and consideration of weight stigma; and v) emphasizing evidence-based medical therapy and cheaper and safer fertility management.Overall, recommendations are strengthened and evidence is improved, but remain generally low to moderate quality. Significantly greater research is now needed in this neglected, yet common condition. Regional health system variation was considered and acknowledged, with a further process for guideline and translation resource adaptation provided.The 2023 International Guideline for the Assessment and Management of PCOS provides clinicians and patients with clear advice on best practice, based on the best available evidence, expert multidisciplinary input and consumer preferences. Research recommendations have been generated and a comprehensive multifaceted dissemination and translation programme supports the Guideline with an integrated evaluation program.This effort was primarily funded by the Australian Government via the National Health Medical Research Council (NHMRC) (APP1171592), supported by a partnership with American Society for Reproductive Medicine, Endocrine Society, European Society for Human Reproduction and Embryology, and the Society for Endocrinology. The Commonwealth Government of Australia also supported Guideline translation through the Medical Research Future Fund (MRFCRI000266). HJT and AM are funded by NHMRC fellowships. JT is funded by a Royal Australasian College of Physicians (RACP) fellowship. Guideline development group members were volunteers. Travel expenses were covered by the sponsoring organizations.

A Swedish population-based matched cohort study 2023 Ingår i: eClinicalMedicine. - : Elsevier. - 2589-5370. ; 65 Tidskriftsartikel (refereegranskat)abstract Background: The incidence of melanoma in situ (MIS) is increasing even more rapidly than the incidence of cutaneous malignant melanoma (CMM). No previous studies have in detail investigated the survival in individuals diagnosed with MIS compared to the general population.Methods: This population-based study included individuals with MIS diagnosed in Sweden between 2001 and 2010 and randomly selected MIS-free comparators matched on age, sex and county of residence. Exclusion criterion was a previous CMM. Data on socioeconomic status (SES) including educational level, income and marital status, comorbidity and cause of death were obtained from population-based registers. Overall survival (OS) was estimated by the Kaplan-Meier method. The mortality risk adjusted for SES and comorbidity was assessed by multivariable Cox regression analyses.Findings: The survival analyses included 7963 cases and 39,662 comparators. Median age at MIS diagnosis were 63 (IQR 50-75) and 67 (IQR 57-76) years in women and men respectively. Median follow-up time was 120 months (IQR 102-152 months). In individuals with MIS, the ten-year OS was 77% (95% CI 0.76-0.78) compared to 72% (95% CI 0.72-0.73) in comparators. The MIS patients had a higher SES and lower comorbidity burden than the comparators. In a fully adjusted multivariable analysis, including 7772 cases and 38,103 comparators, the mortality was significantly lower in women with MIS (HR 0.88, 95% CI 0.82-0.94) compared to the background population. The corresponding estimate in men was HR 0.94 (95% CI 0.88-1.0). The risk of melanoma-related deaths during the study period was ten-fold higher in MIS patients.Interpretation: Despite being at increased risk of developing CMM, MIS patients had a better OS compared to their matched comparators from the background population, findings which could not fully be explained by differences in SES and comorbidity. Our results are reassuring and should be communicated to patients who have been diagnosed with MIS.
3.	Decker, Ralph, 1968, et al. (författare) Case report of a girl with secondary amenorrhea associated with aurantiasis cutis 2016 Ingår i: Hormone Research in Paediatrics. - : S. Karger AG. - 1663-2818 .- 1663-2826. Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract Introduction: --- Aurantiasis cutis is a condition of yellowish or golden skin discoloration that can result from eating excessive amounts of foods containing carotene leading to hypercarotenemia(1), described causing secondary amenorrhea(2). Objective & hypothesis: --- Hypercarotenemia can cause secondary amenorrhea without overconsumption of excessive quantities of carotene. Results: --- Laboratory tests showed a ß-Carotene level more than the 2-fold above the upper reference level. Hyperbilirubinemia could be excluded. Hypogonadotropic hypogonadism was not present. There was no evidence for adrenal dysfunction. Liver function tests were normal. Material/ Methods: --- A 16-year-old girl presented to our endocrine outpatient clinic with a 2-year history of varying yellow discoloration of her skin and secondary amenorrhea. The findings of the general physical examination were normal, but there was a marked yellow discoloration of the palms, soles, and nasolabial folds. A dietary history revealed a low carotene diet, but also a low carbohydrate diet. BMI was 19.9 kg/m² (-0.2 SDS) without signs of anorexia. Discussion: --- In this girl we observed hypercarotenemia associated with secondary nonhypothalamic amenorrhea in absence of excess external intake of carotenes. This suggests an intrinsic reason due to a polymorphism(3) in ß-carotene 15,15'-monooxygenase (BCO)(4), an enzyme breaking down carotenes to vitamin A(5). Phenotype-genotype association studies are needed to confirm this hypothesis. Conclusion: --- Secondary non-hypothalamic amenorrhea can be associated with hypercarotenemia. References: --- 1.

(författare) Peripheral administration of bovine GH regulates the expression of cerebrocortical beta-globin, GABAB receptor 1, and the Lissencephaly-1 protein (LIS-1) in adult hypophysectomized rats. 2011 Ingår i: Growth hormone & IGF research : official journal of the Growth Hormone Research Society and the International IGF Research Society. - : Elsevier BV. - 1532-2238. ; 21:1, s. 16-24 Tidskriftsartikel (refereegranskat)abstract Growth hormone (GH) therapy substantially improves several cognitive functions in hypopituitary experimental animals and in humans. Although a number of biochemical correlates to these effects have been characterized, there are no comprehensive analysis available examining effects of GH on the brain. Hypophysectomized female rats were given replacement therapy with cortisol and thyroxine (=hx). Subcutaneous infusions of bovine GH (bGH, henceforth designated GH) were supplied in osmotic minipumps for 6 days (=hx+GH). To evaluate whether GH normalized specific transcript expression levels in cerebral cortex, pituitary-intact rats were used as normal controls. DNA microarrays (Affymetrix) of cerebrocortical samples showed that 24 transcripts were changed by more than 1.5-fold by GH treatment in addition to being normalized by GH treatment. The expression of three selected highly regulated transcripts was confirmed by quantitative real-time polymerase chain reaction analysis. These were the GABAB receptor 1, Lissencephaly-1 protein (LIS-1), and hemoglobin b or beta-globin. A similar regulation was found for hemoglobin b also in the hippocampus. Both the GABAB receptor 1 and hemoglobin b may have importance for the previously described neuroprotective and perhaps cognitive potential of GH treatment. Altogether, these results show that short term GH treatment affects a number of transcripts in cerebral cortex with various biological functions. These transcripts represent potential novel mechanisms by which GH can interact with the brain.

(författare) ADP-ribosylating adjuvant reveals plasticity in cDC1 cells that drive mucosal Th17 cell development and protection against influenza virus infection 2022 Ingår i: Mucosal Immunology. - : Elsevier BV. - 1933-0219. ; 15:4, s. 745-761 Tidskriftsartikel (refereegranskat)abstract Migratory dendritic cells expressing CD103 are the targets for mucosal vaccines. These belong to either of two lineage-restricted subsets, cDC1 or cDC2 cells, which have been linked to priming of functionally distinct CD4 T cells. However, recent studies have identified plasticity in cDC2 cells with overlapping functions with cDC1 cells, while the converse has not been reported. We genetically engineered a vaccine adjuvant platform that targeted the cholera toxin A1 (CTA1) ADP-ribosylating enzyme to CD103(+) cDC1 and cDC2 cells using a single-chain antibody (scFv) to CD103. Unexpectedly, intranasal immunization with the CTA1-svFcCD103 adjuvant modified cDC1 cells to effectively prime Th17 cells, a function previously limited to cDC2 cells. In fact, cDC2 cells were dispensible, while cDC1 cells, lacking in Batf3-/- mice, were critical. Following intranasal immunizations isolated cDC1 cells from mLN exclusively promoted Rorgt(+) T cells and IL-17, IL-21, and IL-22 production. Strong CD8 T cell responses through antigen cross presentation by cDC1 cells were also observed. Single-cell RNAseq analysis revealed upregulation of Th17-promoting gene signatures in sorted cDC1 cells. Gene expression in isolated cDC2 cells was largely unaffected. Our finding represents a major shift of paradigm as we have documented functional plasticity in cDC1 cells.

(författare) Agreement between self-reported and measured height, weight and body mass index in old age : a longitudinal study with 20 years of follow-up 2010 Ingår i: Age and Ageing. - : Oxford University Press. - 0002-0729 .- 1468-2834. ; 39:4, s. 445-451 Tidskriftsartikel (refereegranskat)abstract Background: self-reported body mass index (BMI) based on self-reported height and weight is a widely used measure of adiposity in epidemiological research. Knowledge about the accuracy of these measures in late life is scarce.Objective: the study aimed to evaluate the accuracy and changes in accuracy of self-reported height, weight and BMI calculated from self-reported height and weight in late life.Design: a longitudinal population-based study with five times of follow-up was conducted.Participants: seven hundred seventy-four community-living men and women, aged 40–88 at baseline (mean age 63.9), included in The Swedish Adoption/Twin Study of Aging.Methods: participants self-reported their height and weight in a questionnaire, and height and weight were measured by experienced research nurses at an in-person testing five times during a 20-year period. BMI was calculated as weight (kilogramme)/height (metre)2.Results: latent growth curve modelling showed an increase in the mean difference between self-reported and measured values over time for height (0.038 cm/year) and BMI (0.016 kg/m2/year), but not for weight.Conclusions: there is a very small increase in the mean difference between self-reported and measured BMI with ageing, which probably would not affect the results when self-reported BMI is used as a continuous variable in longitudinal studies.

(författare) Bone mineral density in patients with Crohn's disease during long-term treatment with azathioprine 1998 Ingår i: Journal of Internal Medicine. - 1365-2796. ; 243:2, s. 123-126 Tidskriftsartikel (refereegranskat)abstract OBJECTIVES: To ascertain whether patients with Crohn's disease treated with azathioprine maintained bone mineral mass better than patients treated with steroids alone. DESIGN: Retrospective study. SETTING: University Hospital of Malmo, Sweden. SUBJECTS: A total of 59 patients with ileocolonic, ileocaecal or colonic Crohn's disease. METHODS: Bone mass was assessed by dual photon X-ray absorptiometry at the level of L2-L4. RESULTS: Patients treated with a high lifetime dose of steroids (> 5 g prednisolone) had significantly (P = 0.011) lower Z-score of L2-L4 (-0.87 +/- 1.11; 11 SD) than steroid-treated patients, who had received a low dose of prednisolone (< 5 g) (0.08 +/- 1.16 SD). Azathioprine did not negatively influence the steroid effect on bone mineral density. CONCLUSIONS: Azathioprine does not seem to affect bone mineral density by itself. However, by being steroid-saving, it seems to conserve bone mineral mass in patients with Crohn's disease.

Several promising steps toward individualized therapy have been taken recently due to increased knowledge of molecular biology. Multidisciplinary conferences for treatment planning and the centralization to tertiary surgical centers improve quality of surgery and survival. The primary treatment of EOC is radical surgery followed by adjuvant chemotherapy with carboplatin and paclitaxel. Bevacizumab added to the chemotherapy and used as maintenance treatment is standard in the primary treatment of patients with residual tumor or inoperable patients. The PARP inhibitor olaparib is recommended as maintenance treatment of women with platinum sensitive relapsed BRCA mutated high-grade serous EOC who have responded to platinum-based chemotherapy. BRCA testing should be offered to women with EOC. In platinum-resistant recurrence addition of bevacizumab to chemotherapy should be considered.
10.	Nordahl, Emma, et al. (författare) Domain 5 of high molecular weight kininogen is antibacterial. 2005 Ingår i: Journal of Biological Chemistry. - 1083-351X. ; 280:41, s. 34832-34839 Tidskriftsartikel (refereegranskat)abstract Antimicrobial peptides are important effectors of the innate immune system. These peptides belong to a multifunctional group of molecules that apart from their antibacterial activities also interact with mammalian cells and glycosaminoglycans and control chemotaxis, apoptosis, and angiogenesis. Here we demonstrate a novel antimicrobial activity of the heparin-binding and cell-binding domain 5 of high molecular weight kininogen. Antimicrobial epitopes of domain 5 were characterized by analysis of overlapping peptides. A peptide, HKH20 (His(479) - His(498)), efficiently killed the Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa and the Gram-positive Enterococcus faecalis. Fluorescence microscopy and electron microscopy demonstrated that HKH20 binds to and induces breaks in bacterial membranes. Furthermore, no discernible hemolysis or membrane-permeabilizing effects on eukaryotic cells were noted. Proteolytic degradation of high molecular weight kininogen by neutrophil-derived proteases as well as the metalloproteinase elastase from P. aeruginosa yielded fragments comprising HKH20 epitopes, indicating that kininogen-derived antibacterial peptides are released during proteolysis.

Phylogenetic analysis, sequence analyses, and structural modeling studies paired with antimicrobial assays of peptides from known C3a sequences showed that, in particular in vertebrate C3a, crucial structural determinants governing antimicrobial activity have been conserved during the evolution of C3a. Thus, regions of the ancient C3a from Carcinoscorpius rotundicauda as well as corresponding parts of human C3a exhibited helical structures upon binding to bacterial lipopolysaccharide permeabilized liposomes and were antimicrobial against Gram-negative and Gram-positive bacteria. Human C3a and C4a (but not C5a) were antimicrobial, in concert with the separate evolutionary development of the chemotactic C5a. Thus, the results demonstrate that, notwithstanding a significant sequence variation, functional and structural constraints imposed on C3a during evolution have preserved critical properties governing antimicrobial activity.

(författare) Proportions of Polyunsaturated Fatty Acids in Umbilical Cord Blood at Birth Are Related to Atopic Eczema Development in the First Year of Life 2021 Ingår i: Nutrients. - : MDPI AG. - 2072-6643. ; 13:11 Tidskriftsartikel (refereegranskat)abstract Atopic eczema, the most common atopic disease in infants, may pave the way for sensitization and allergy later in childhood. Fatty acids have immune-regulating properties and may regulate skin permeability. Here we examine whether the proportions of fatty acids among the infant and maternal plasma phospholipids at birth were associated with maternal dietary intake during pregnancy and development of atopic eczema during the first year of age in the Nutritional impact on Immunological maturation during Childhood in relation to the Environment (NICE) birth cohort. Dietary data were collected with a semi-quantitative food frequency questionnaire, fatty acids were measured with GC-MS and atopic eczema was diagnosed by a pediatric allergologist at 12 months of age. We found that higher proportions of n-6 PUFAs (including arachidonic acid) but lower proportions of n-3 PUFAs (including DPA) in the infant's phospholipids at birth were associated with an increased risk of atopic eczema at 12 months of age. The n-6 and n-3 PUFAs were related to maternal intake of meat and fish, respectively. Our results suggest that prenatal exposure to unsaturated fatty acids is associated with eczema development in the infant. Maternal diet during pregnancy may partly explain the fatty acid profiles in utero.

14.	Lundquist, Ingmar, et al. (författare) Monoamines in pancreatic islets of guinea pig, hamster, rat, and mouse determined by high performance liquid chromatography 1989 Ingår i: Pancreas. - 0885-3177. ; 4:6, s. 662-667 Tidskriftsartikel (refereegranskat)abstract Previous studies on the occurrence of catecholamines and serotonin in pancreatic islets using various histochemical and chemical methods have given widely different results. We therefore performed a comparative analysis of these amines in whole pancreas and islet tissue from hamster, guinea pig, rat, and mouse by the use of high performance liquid chromatography. Whole pancreas of guinea pig, hamster, and rat had a norepinephrine concentration of approximately 1.1 [mu]mol/kg of pancreatic wet weight. The mouse pancreas had less than one-half of that concentration. Epinephrine and dopamine concentrations were on the order of 0.02 [mu]mol/kg of pancreatic wet weight in all four species. The serotonin concentration was 2.1 [mu]mol/kg of pancreatic wet weight in the guinea pig pancreas and approximately 0.2 [mu]mol/kg in the other three species studied. The catecholamine concentrations were much higher in the pancreatic islets than in the exocrine pancreas. Thus, the norepinephrine concentration was approximately 35 [mu]mol/kg of islet wet weight in hamster islets and 5-10 [mu]mol/kg in rat, guinea pig, and mouse islets. The epinephrine concentration in islet tissue ranged between 1 and 7 [mu]mol/kg of islet wet weight and the dopamine concentration between 0.5 and 4 [mu]mol/kg except for guinea pig islets (12 [mu]mol/kg). The islet tissue in the mouse, rat, and guinea pig contained disproportionately more epinephrine and dopamine relative to norepinephrine than did the exocrine pancreas. Chemical sympathectomy (6- hydroxydopamine treatment) in the mouse reduced the norepinephrine and epinephrine concentrations in islet tissue to nondetectable levels, whereas the dopamine concentration was essentially unchanged, thus suggesting an extraneuronal source of this amine in addition to its occurrence in adrenergic nerves. The islets of hamster, rat, and mouse contained no serotonin, whereas guinea pig islets contained approximately 275 [mu]mol/kg of islet wet weight. We conclude that, although species differences exist, the pancreatic islets have markedly higher levels of catecholamines than the exocrine pancreas, and that serotonin occurs in the exocrine pancreas of all four species studied but in the endocrine pancreas only in the guinea pig.
15.	Alesi, Simon, et al. (författare) Efficacy and safety of anti-androgens in the management of polycystic ovary syndrome: a systematic review and meta-analysis of randomised controlled trials. 2023 Ingår i: EClinicalMedicine. - 2589-5370. ; 63 Tidskriftsartikel (refereegranskat)abstract Anti-androgens and combined oral contraceptive pills (COCPs) may mitigate hyperandrogenism-related symptoms of polycystic ovary syndrome (PCOS). However, their efficacy and safety in PCOS remain unclear as previous reviews have focused on non-PCOS populations. To inform the 2023 International Evidence-based Guideline in PCOS, we conducted the first systematic review and meta-analysis investigating the efficacy and safety of anti-androgens in the management of hormonal and clinical features of PCOS.We systematically searched MEDLINE, Embase, PsycInfo, All EBM reviews, and CINAHL up to 28th June 2023 for randomised controlled trials (RCTs) examining oral anti-androgen use, alone or in combination with metformin, COCPs, lifestyle, or other interventions, in women of any age, with PCOS diagnosed by Rotterdam, National Institutes of Health or Androgen Excess & PCOS Society criteria, and using a form of contraception. Non-English studies and studies of less than 6 months duration or which used the same anti-androgen regimen in both/all groups were excluded in order to establish efficacy for the clinical outcomes of interest. Three authors screened articles against selection criteria and assessed risk of bias and quality using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) framework. Critical outcomes (prioritised during guideline development for GRADE purposes) included weight, body mass index (BMI), irregular cycles, hirsutism, liver function, and quality of life. Random effects meta-analyses were conducted where appropriate. This study is registered with PROSPERO, CRD42022345640.From 1660 studies identified in the search, 27 articles comprising 20 unique studies were included. Of these, 13 studies (n=961) were pooled in meta-analysis. Seven studies had a high risk of bias, nine moderate and four low. Anti-androgens included finasteride, flutamide, spironolactone, or bicalutamide. In meta-analysis, anti-androgens+lifestyle were superior to metformin+lifestyle for hirsutism (weighted mean difference [WMD] [95% CI]:-1.59 [-3.06,-0.12], p=0.03; I2=74%), SHBG (7.70nmol/l [0.75, 14.66], p=0.03; I2=0%), fasting insulin and fasting insulin: glucose ratio (-2.11 μU/ml [-3.97,-0.26], p=0.03; I2=0% and-1.12 [-1.44,-0.79], p<0.0001, I2=0%, respectively), but were not superior to placebo+lifestyle for hirsutism (-0.93, [-3.37, 1.51], p=0.45; I2=76%) or SHBG (9.72nmol/l [-0.71, 20.14], p=0.07; I2=31%). Daily use was more effective for hirsutism than use every three days (-3.48 [-4.58,-2.39], p<0.0001, I2=1%), and resulted in lower androstenedione levels (-0.30ng/ml [-0.50,-0.10], p=0.004; I2=0%). Combination treatment with anti-androgens+metformin+lifestyle resulted in lower testosterone compared with metformin+lifestyle (-0.29nmol/l [-0.52,-0.06], p=0.01; I2=61%), but there were no differences in hirsutism when anti-androgens+metformin+lifestyle were compared with either anti-androgens+lifestyle or metformin+lifestyle. In limited meta-analyses (n=2 trials), combining anti-androgens with COCP resulted in poorer lipid profiles compared with COCP±placebo, with no differences in other outcomes.Current evidence does not support the use of anti-androgens preferentially to COCPs to treat hyperandrogenism in PCOS. Anti-androgens could be considered to treat hirsutism in PCOS, where COCPs are contraindicated, poorly tolerated, or present a sub-optimal response after a minimum 6-month period, with consideration of clinical context and individual risk factors and characteristics.National Health and Medical Research Council (NHMRC) of Australia Monash University.

Combinedwith screening of certain risk groups it is probably one effectiveway of preventing C trachomatis infections. Preventing C trachomatisby primary prevention such as information and counselling is,however, still of great importance.

Few previous population-based studies have quantified and compared cancer risks according to graft type and with long-term follow-up. Using nationwide Swedish registers, we identified 10,476 recipients transplanted from 1970 to 2008 and followed them for cancer occurrence. Relative risks of cancer in comparison with the general population were expressed as standardized incidence ratios (SIR) and within the transplanted cohort as incidence rate ratios (IRR). During a total follow-up of 93,432 person-years, patients were diagnosed with 1,175 cancers excluding SCC, and with 2,231 SCC, SIRcancer excl SCC 2.4 (95% CI, 2.2–2.5); SIRSCC 121 (95% CI, 116–127). Cancer risks were most increased among heart and/or lung recipients SIRcancer excl SCC 3.3 (95% CI, 2.8–4.0); SIRSCC 198 (95% CI, 174–224), followed by kidney SIRcancer excl SCC 2.3 (95% CI, 2.1–2.4); SIRSCC 121 (95% CI, 116–127) and liver recipients SIRcancer excl SCC 2.3 (95% CI, 1.9–2.8); SIRSCC 32 (95% CI, 24–42). During follow-up, risk of cancer excluding SCC remained stable while risk of SCC tripled over 20 years irrespective of graft type, partly due to a subgroup of patients developing new SCCs at a rapidly increasing rate. In summary, post-transplant cancer risk varied by transplanted organ and by cancer site, with the bulk of the excess risk driven by an exceptionally high and accelerating risk of SCC. These findings underscore the importance of regular skin screening in organ transplant recipients.

(författare) Evaluation of skin reactions during proton beam radiotherapy : patient-reported versus clinician-reporte 2021 Ingår i: Technical innovations & patient support in radiation oncology. - : Elsevier. - 2405-6324. ; 19, s. 11-17 Tidskriftsartikel (refereegranskat)abstract Background: Skin reaction is a common side-effect of radiotherapy and often only assessed as clinician-reported outcome (CRO). The aim was to examine and compare patient-reported outcome (PRO) of skin reactions with CRO for signs of acute skin reactions for patients with primary brain tumour receiving proton beam radiotherapy (PBT). A further aim was to explore patients' experiences of the skin reactions.Methods: Acute skin reactions were assessed one week after start of treatment, mid-treatment and end of treatment among 253 patients with primary brain tumour who underwent PBT. PRO skin reactions were assessed with the RSAS and CRO according to the RTOG scale. Fleiss' kappa was performed to measure the inter-rater agreement of the assessments of skin reactions.Results: The results showed a discrepancy between PRO and CRO acute skin reactions. Radiation dose was associated with increased skin reactions, but no correlations were seen for age, gender, education, occupation, other treatment or smoking. There was a poor agreement between patients and clinicians (κ = -0.016) one week after the start of PBT, poor (κ = -0.045) to (κ = 0.396) moderate agreement at mid treatment and poor (κ = -0.010) to (κ = 0.296) moderate agreement at end of treatment. Generally, patients' symptom distress toward skin reactions was low at all time points.Conclusion: The poor agreement between PRO and CRO shows that the patient needs to be involved in assessments of skin reactions for a more complete understanding of skin reactions due to PBT. This may also improve patient experience regarding involvement in their own care.

High degree of leisure-time, but not work-related, physical activity, high occupational class, and high body mass index (BMI) protected against hip fracture. Smoking, tall stature, interim stroke, and dementia increased the risk. PURPOSE: The purpose was to prospectively study risk factors for hip fracture in men. METHODS: We studied midlife determinants of future hip fractures in 7,495 randomly selected men aged 46-56 years in Gothenburg, Sweden. The subjects were investigated in 1970-1973 and followed for over 30 years. Questionnaires were used regarding lifestyle factors, psychological stress, occupational class, and previous myocardial infarction, stroke, and diabetes mellitus. Alcohol problems were assessed with the aid of registers. Using the Swedish hospital discharge register, data were collected on intercurrent stroke and dementia diagnoses and on first hip fractures (X-ray-verified). RESULTS: Four hundred fifty-one men (6%) had a hip fracture. Age, tall stature, low occupational class, tobacco smoking, alcoholic intemperance, and interim stroke or dementia were independently associated with the risk of hip fracture. There were inverse associations with leisure-time physical activity, BMI, and coffee consumption. The gradient of risk for one standard deviation of multivariable risk decreased with time since measurement yet was a good alternative to dual energy X-ray absorptiometry measurements. CONCLUSIONS: High degree of leisure-time physical activity, high occupational class, and high BMI protected against hip fracture. However, work-related physical activity was not protective. Smoking, tall stature, and interim stroke or dementia increased the risk.

We wanted to revalidate a 4-item clinical risk score and evaluate a portable heel bone mineral density (BMD) technique regarding hip and fragility fracture risk among elderly women. Methods In a population-based prospective cohort study we used clinical risk factors from a baseline questionnaire and heel BMD to predict a two-year hip and fragility fracture outcome for women, in a fracture preventive program. Calcaneal heel BMD was measured by portable dual X-ray laser absorptiometry (DXL) and compared to hip BMD, measured with stationary dual X-ray absorptiometry (DXA) technique. Results Seven women suffered hip fracture and 14 women fragility fracture/s (at hip, radius, humerus and pelvis) among 285 women; 60% having heel BMD ≤ -2.5 SD. The 4-item FRAMO (Fracture and Mortality) Index combined the clinical risk factors age ≥80 years, weight <60 kg, prior fragility fracture, and impaired rise-up ability. Women having 2-4 risk factors showed odds ratio (OR) for hip fracture of 5.9 and fragility fracture of 4.4. High risk group hip fracture risk was 2.8% annually compared to 0.5% for the low risk majority (69%). Heel BMD showed hip fracture OR of 3.1 and fragility fracture OR of 2.6 per SD decrease. For 30 DXA assessed participants mean hip BMD at -2.5 SD level corresponded to a lower BMD at the heel. Five of seven hip fractures occurred within a small risk group of 32 women, identified by high FRAMO Index + prior fragility fracture + heel T-score ≤-3.5 SD. Conclusions In a follow-up study we identified high risk groups for hip and fragility fracture with our plain 4-item risk model. Increased fracture risk was also related to decreasing heel BMD in calcaneal bone, measured with a mobile DXL technique. A combination of high FRAMO Index, prior fragility fracture, and very low BMD restricted the high risk group to 11%, among whom most hip fractures occurred (71%). These practical screening methods could eventually reduce hip fracture incidence by concentrating preventive resources to high fracture risk women.

The aim of this study was to evaluate the efficacy of 10 mg oral prednisolone twice daily for four days in addition to conventional therapy.Patients attending general practice clinics in Far North Queensland, Australia, for acute painful otitis externa were given a study capsule with either 10 mg prednisone or placebo.Seventy-three patients were randomised. Results from 19 patients in the intervention group and 11 patients in the control group were analysed. Oral corticosteroids did not decrease the time to being completely pain-free but decreased the time for pain to reduce from more than 'moderate pain' to less than 'moderate pain', from 3.7 days to 2.4 days (P= 0.012, log rank test).Oral corticosteroids seem to be effective in reducing more than 'moderate pain' to less than 'moderate pain'. However, this result needs to be confirmed in a larger trial.

Tidskriftsartikel (refereegranskat)abstract A 2-year-old girl presented with an intensely itching subcutaneous nodule on the front of a thigh. The nodule persisted for 10 months until it was excised. Subsequent investigation for malignancy and systemic disease showed no pathological findings. The diagnosis, persistent itching vaccination granuloma, was revealed by hazard almost 2 years after the onset of symptoms. Persistent itching subcutaneous nodules at the injection site for aluminium containing vaccines (mostly diphtheria-tetanus-pertussis combination vaccines for primary immunisation of infants) may appear with a long delay after the vaccination (months), cause prolonged itching (years) and are often associated with contact allergy to aluminium. The condition is poorly recognised in Health Care which may lead to prolonged symptoms and unnecessary investigations.

Both vaccines were adsorbed to an Al adjuvant. Altogether 38 children (0.83 %) with itching granulomas were identified, epicutaneously tested for Al sensitisation and followed yearly. Contact allergy to Al was verified in 85 %. The median duration of symptoms was 22 months in those hitherto recovered. The frequency of granulomas induced by Infanrix® was >0.66 % and by Prevenar >0.35 %. The risk for granulomas increased from 0.63 to 1.18 % when a second Al-adsorbed vaccine was added to the schedule. Conclusion: Long-lasting itching vaccination granulomas are poorly understood but more frequent than previously known after infant vaccination with commonly used diphtheria-tetanus-pertussis-polio-Haemophilus influenzae type b and pneumococcal conjugate vaccines. The risk increases with the number of vaccines given. Most children with itching granulomas become contact allergic to aluminium. Itching vaccination granulomas are benign but may be troublesome and should be recognised early in primary health care to avoid unnecessary investigations, anxiety and mistrust.

As part of the Swedish strategic program against antibiotic resistance in intensive care (ICU-Strama), we have surveyed the distribution of species and ABR in isolates from patients admitted to a Swedish burn center at Linkoping University Hospital from 1994 through 2012. In an international comparison Strama has been successful in reducing the antibiotic consumption among animals and humans in primary care. The aim of this study was to investigate the antibiotic consumption pressure and resistance rates in a Swedish burn unit. Methods: Microbiology data, total body surface area (TBSA), patient days, and mortality were collected from a hospital database for all patients admitted to the Burn Center at the University Hospital of Linkoping from April 1994 through December 2012. Results: A total of 1570 patients were admitted with a mean annual admission rate of 83 patients (range: 57-152). 15,006 microbiology cultures (approximately 10 per patient) were collected during the study period and of these 4531 were positive (approximately 3 per patient). The annual mean total body surface area (TBSA) was 13.4% (range 9.5-18.5) with an annual mortality rate of 5.4% (range 1-8%). The MRSA incidence was 1.7% (15/866) which corresponds to an MRSA incidence of 0.34/1000 admission days (TAD). Corresponding figures were for Escherichia coli resistant to 3rd generation cephalosporins (ESBL phenotype) 8% (13/170) and 0.3/TAD, Klebsiella spp. ESBL phenotype 5% (6/134) and 0.14/TAD, carbapenem resistant Pseudomonas aeruginosa 26% (56/209) and 1.28/TAD, and carbapenem resistant Acinetobacter spp. 3% (2/64) and 0.04/TAD. Conclusions: Our results show a sustained low risk for MRSA and high, although not increasing, risk for carbapenem resistant P. aeruginosa.

The infections often occurunnoticed, but severe disease as well as long-term sequelae are part of the symptom spectrum. The prevalence variesamong subpopulations and with time. The aim of this study was to describe the seroprevalence of ImmunoglobulinG against Herpes simplex 1, Herpes simplex 2, Epstein-Barr virus and Cytomegalovirus in the adult Swedish populationover a time period of several decades.Methods: Serum samples (n = 892) from biobanks, originating from 30-year-old women, 50-year-old menand 50-year-old women sampled between 1975 and 2018, were analyzed for presence of anti-herpesvirus antibod-ies. Linear regression analysis was used to test for a correlation between birth year and seroprevalence. Multiple linearregression analysis was used to differentiate between other factors such as age and gender.Results: Birth year correlated negatively with the prevalence of immunoglobulin G against Herpes simplex 1and Epstein-Barr virus (p = 0.004 and 0.033), and positively with Immunoglobulin G against Cytomegalovirus(p = 0.039). When participant categories were analyzed separately, birth year correlated negatively with the preva-lence of Immunoglobulin G against Herpes simplex 1 and Herpes simplex 2 (p = 0.032 and 0.028) in 30-year-old women,and with the prevalence of Immunoglobulin G against Cytomegalovirus in 50-year-old men (p = 0.011).Conclusions: The prevalence of Immunoglobulin G against Herpes simplex 1, Herpes simplex 2 and Epstein-Barr virusdecreases in later birth cohorts.

The objective was to determine whether exosomes are present in the liver circulation, and to ascertain whether these may originate from melanoma cells.

Reoperations and unnecessary removal of healthy tissue could be reduced if non-invasive imaging techniques were available for presurgical tumor delineation. However, no technique has gained widespread clinical use to date due to shallow imaging depth or the absence of functional imaging capability. Photoacoustic (PA) imaging is a novel technology that combines the strengths of optical and ultrasound imaging to reveal the molecular composition of tissue at high resolution. Encouraging results have been obtained from previous animal and human studies on melanoma, but there is still a lack of clinical data. This is the largest study of its kind to date, including 52 melanomas and nevi. 3D multiwavelength PA scanning was performed ex vivo, using 59 excitation wavelengths from 680 nm to 970 nm. Spectral unmixing over this broad wavelength range, accounting for the absorption of several tissue chromophores, provided excellent contrast between healthy tissue and tumor. Combining the results of spectral analysis with spatially resolved information provided a map of the tumor borders in greater detail than previously reported. The tumor dimensions determined with PA imaging were strongly correlated with those determined by histopathological examination for both melanomas and nevi.

The new AJCC 8th edition was recently launched and introduced several changes in melanoma staging, particularly for stage III. We conducted a population-based registry study with the purpose to evaluate the impact and prognostic accuracy of the new classification in Sweden.Consecutive patients diagnosed with stage III melanoma between January 2005 and September 2017 were identified by the Swedish Melanoma Registry (SMR) and included for analyses. Patients with multiple primary melanomas were excluded. Patients were classified according to the AJCC 7th as well as the 8th edition. Melanoma-specific survival (MSS) was retrieved from the Swedish Cause of Death Registry.A total of 2067 eligible patients were identified from the SMR; 1150 patients (57%) changed stage III subgroup when reclassified according to the AJCC 8th edition. The median 5- and 10-year MSS for the whole cohort of stage III melanoma patients was 59% and 51% respectively. The MSS for substage IIIA, B, and C were all improved when patients were reclassified by using to the AJCC 8th edition. The newly defined substage IIID had the worst prognosis with a 10-year MSS of 16%.A high proportion of patients diagnosed with stage III melanoma in Sweden between 2005 and 2017 was restaged to another subgroup, when they were reclassified according to the AJCC 8th of staging manual. We established an improved MSS for all substages compared with the former AJCC 7th edition. This may have implications on decisions about adjuvant treatment.

These lesions can serve as an excellent model system for studying genetic changes associated with the inception of skin SCC. In the present study, five such lesions of the skin, three AKs and two AK+CIS, from three patients were short-term cultured and analyzed cytogenetically. One of the patients (case 3) had also an SCC in addition to three premalignant lesions. All lesions, but one, showed clonal karyotypic abnormalities. The recurrent changes identified were numerical, that is, +7 and +20. The structural rearrangements found in three AK were different, but it could be noted that the distal part of the long arm of chromosome 4 was involved in two AK and the SCC of case 3A. It was also interesting that chromosome 1 participated in structural rearrangements in three AK with band 1p31 being involved in two tumors. The karyotypic profile of these lesions is compared with that of skin SCC; it turns out that the general patterns are different in the sense that the SCC more often have complex karyotypes and display unbalanced aberrations involving the centromeric regions. Some karyotypic similarities between the SCC and their precursors are revealed. The fact that the structural rearrangements involving chromosomal band 3p13 and the centromeric region of chromosome 3 in AK are common features for many types of malignant tumors, including skin SCC, indicates that these changes are early genetic events associated with malignant transformation.

This patient group accounts for the majority of melanomas diagnosed in western countries today, and better prognostic information is needed.Objectives The aim of this study was to use established prognostic factors such as ulceration, tumour thickness and Clark’s level of invasion for risk stratification of T1 cutaneous melanoma.Methods From 1990 to 2008, the Swedish Melanoma Register included 97% of all melanomas diagnosed in Sweden. Altogether, 13 026 patients with T1 melanomas in clinical stage I were used for estimating melanoma-specific 10- and 15-year mortality rates. The Cox regression model was used for further survival analysis on 11 165 patients with complete data.Results Ulceration, tumour thickness and Clark’s level of invasion all showed significant, independent, long-term prognostic information. By combining these factors the patients could be subdivided into three risk groups: a low-risk group (67·9% of T1 cases) with a 10-year melanoma-specific mortality rate of 1·5% (1·2–1·9%); an intermediate-risk group (28·6% of T1 cases) with a 10-year mortality rate of 6·1% (5·0–7·3%); and a high-risk group (3·5% of T1 cases) with a 10-year mortality rate of 15·6% (11·2–21·4%). The high- and intermediate-risk groups accounted for 66% of melanoma deaths within T1.Conclusions Using a population-based melanoma register, and combining ulceration, tumour thickness and Clark’s level of invasion, three distinct prognostic subgroups were identified.

The patients were followed through 2012 in the national Cause-of-Death Register.Results: Logistic and Cox regression analyses adjusting for age at diagnosis, tumour site, and health care region were carried out. The odds ratio for being diagnosed with thicker tumours was significantly reduced (P = 0·0008) and the CMM-specific survival significantly improved in men diagnosed 2007-2011 compared to men diagnosed 1997-2001 (hazard ratio=0·81; 95% CI 0·72-0·91, P = 0·0009) while the corresponding differences for women were not significant. Women were diagnosed with significantly thicker tumours during 2002-2006 and a tendency towards decreased survival was observed compared to those diagnosed earlier 1997-2001 and later 2007-2011.Conclusion: In Sweden, the CMMs of men are detected earlier over time and this seems to be followed by an improved CMM-specific survival for men. Women are still diagnosed with considerably thinner tumours and they experience a better survival than men.

Information about psoriasis and PsA diagnosis was retrieved through the Swedish National Patient Register and questionnaires.During follow-up for up to 26 years, bariatric surgery was associated with a lower incidence of psoriasis compared with usual care (number of events=174; hazard ratio 0.65; 95% CI: 0.47-0.89; P=0.008). Both smoking and a longer duration of obesity were independently associated with a higher risk for psoriasis. No significant difference was detected among the three surgical procedures in terms of lowering the risk of developing psoriasis. The association between bariatric surgery and psoriasis incidence was not influenced by baseline confounders. No significant difference in the risk of developing PsA (number of events=46) was detected when comparing the surgery and the control groups.This study shows that bariatric surgery is associated with a lower risk of developing psoriasis compared with usual care.

Approximately 20% of hereditary PPGL are caused by pathogenic germ line variants in genes of the succinate dehydrogenase complex (SDHx), TMEM127 or MAX. Herein we present guidelines regarding genetic testing of family members and their surveillance based on a thorough literature review. All cases of PPGL are recommended genetic testing for germ line variants regardless of patient and family characteristics. At minimum, FH, NF1, RET, SDHB, SDHD and VHL should be tested. In addition, testing of MEN1, SDHA, SDHAF2, SDHC, TMEM127 and MAX is recommended. Healthy first-degree relatives (and second-degree relatives in the case of SDHD and SDHAF2 which are maternally imprinted) should be offered carrier testing. Carriers of pathogenic variants should be offered surveillance with annual biochemical measurements of methoxy-catecholamines and bi-annual rapid whole-body magnetic resonance imaging and clinical examination. Surveillance should start 5 years before the earliest age of onset in the family and thus only children eligible for surveillance should be offered pre-symptomatic genetic testing. The surveillance of children younger than 15 years needs to be individually designed. Our guidelines will provide a framework for patient management with the possibility to follow outcome via national registries and/or follow-up studies. Together with improved insights into the disease, this may enable optimisation of the surveillance scheme in order to minimise both anxiety and medical complications while ensuring early disease detection.
40.	Nielsen, Kari, et al. (författare) Swedish CDKN2A mutation carriers do not present the atypical mole syndrome phenotype. 2010 Ingår i: Melanoma Research. - 0960-8931. ; Jul 1, s. 266-272 Tidskriftsartikel (refereegranskat)abstract Phenotypic characteristics were examined in melanoma-prone southern Swedish CDKN2A (p16-113insArg/p14ARF-128insSer) mutation families, in relation to the CDKN2A genotype, nevi, clinically atypical nevi (CAN) and melanoma. Individuals from eight melanoma-prone families, with index patients carrying the CDKN2A mutation, were offered skin examinations and genotyping (CDKN2A and MC1R). Ninety-three individuals above 18 years of age participated; 29 invasive melanomas in 16 patients were recorded, all in the 38 verified CDKN2A mutation carriers. Median age at diagnosis was 36 years. Several MC1R variants were observed. A significant correlation to CAN (P=0.01) and red hair colour (P=0.02) could be confirmed in melanoma patients. A positive mutation status (CDKN2A) was correlated to one or more CAN (P=0.007) but neither to blue eyes, red hair colour, heavy freckling nor high number of nevi. For mutation carriers, median total naevus count was 24 and interquartile range was 12-47 (mean 31); whereas for the whole cohort, median total naevus count was 12 and interquartile range was 5-25 (mean 22). No participant fulfilled the atypical mole syndrome phenotype criteria. Melanomas were diagnosed only in mutation carriers, and melanoma diagnosis was statistically correlated to the presence of one or more CAN and red hair colour, supporting the possible synergistic effect of a MC1R mutation on increased risk of melanoma in patients with a CDKN2A mutation. Family history, with verified tumour diagnoses, remains an important clinical tool for finding mutation carriers for referral to clinical geneticists and simultaneous presence of CAN in probable mutation carriers might strengthen this indication. The atypical mole syndrome phenotype was, however, not verified in the studied families and total naevus counts were low.

Shen, Yue, 1981- (författare) Plasminogen : a novel inflammatory regulator that promotes wound healing 2013 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract The plasminogen activator (PA) system has been shown to be intimately involved in wound healing. However, the role of this system in the initiation and resolution of inflammation during healing process remained to be determined. The aims of this thesis were to investigate the molecular mechanism underlying the interaction between the PA system and the inflammatory system during wound healing and to explore the therapeutic potential of plasminogen in various wound-healing models.The role of plasminogen in the inflammatory phase of the healing process of acute and diabetic wounds was studied first. Our data showed that administration of additional plasminogen to wild-type mice accelerates the healing of acute wounds. After injury, both endogenous and exogenous plasminogen are bound to inflammatory cells and are transported to the wound site, which leads to activation of inflammatory cells. In diabetic db/db mice, wound-specific accumulation of plasminogen does not take place and the inflammatory response is impaired. However, when additional plasminogen is injected, plasminogen accumulates in the wound, the inflammatory response is enhanced, the signal transduction cascade is activated and the healing rate is significantly increased. These results indicate that administration of plasminogen may be a novel therapeutic strategy to treat different types of wounds, especially chronic wounds in diabetes.The role of plasminogen at the later stage of wound healing was also studied in plasminogen-deficient mice. Our data showed that even if re-epithelialization is achieved in these mice, a prolonged inflammatory phase with abundant neutrophil accumulation and persistent fibrin deposition is observed at the wound site. These results indicate that plasminogen is also essential for the later phases of wound healing by clearing fibrin and resolving inflammation.The functional role of two physiological PAs during wound healing was further studied in a tympanic membrane (TM) wound-healing model. Our data showed that the healing process was clearly delayed in urokinase-type PA (uPA)-deficient mice but not in tissue-type PA (tPA)-deficient mice. Less pronounced keratinocyte migration, abundant neutrophil accumulation and persistent fibrin deposition were observed in uPA-deficient mice. These results indicate that uPA plays a central role in the generation of plasmin during the healing of TM perforations.Finally the therapeutic potential of plasminogen in the TM wound-healing model was studied. Our data showed that local injection of plasminogen restores the ability to heal TM perforations in plasminogen-deficient mice in a dose-dependent manner. Plasminogen supplementation also potentiates healing of acute TM perforations in wild-type mice, independent of the administration method used. A single local injection of plasminogen in plasminogen-deficient mice can initiate healing of chronic TM perforations resulting in a closed TM with a continuous but rather thick outer keratinocyte layer. Three plasminogen injections lead to a completely healed TM with a thin keratinizing squamous epithelium covering a connective tissue layer that can start to reorganize and further mature to its normal appearance. In conclusion, our results suggest that plasminogen is a promising drug candidate for the treatment of chronic TM perforations in humans. Taken together, our data indicate that plasminogen is a novel inflammatory regulator that promotes wound healing.

(författare) Decreasing prevalence of atopic dermatitis in Swedish schoolchildren : three repeated population-based surveys 2024 Ingår i: British Journal of Dermatology. - : Oxford University Press. - 0007-0963 .- 1365-2133. ; 190:2, s. 191-198 Tidskriftsartikel (refereegranskat)abstract Background: The prevalence of atopic dermatitis (AD) has increased over several decades and now affects about one-fifth of all children in high-income countries (HICs). While the increase continues in lower-income countries, the prevalence of AD might have reached a plateau in HICs.Objectives: To investigate trends in the prevalence of AD and atopic comorbidity in schoolchildren in Sweden.Methods: The study population consisted of three cohorts of children (median age 8 years) in Norrbotten, Sweden, for 1996 (n = 3430), 2006 (n = 2585) and 2017 (n = 2785). An identical questionnaire that included questions from the International Study of Asthma and Allergies in Childhood (ISAAC) protocol was used in all three cohorts. Trends in AD prevalence were estimated, as well as trends in atopic comorbidity. AD prevalence was estimated both according to the ISAAC definition of AD and by adding the reported diagnosis by a physician (D-AD).Results: The prevalence of AD decreased in the last decade, from 22.8% (1996) and 21.3% (2006) to 16.3% (2017; P < 0.001). The prevalence of D-AD was lower, but the same pattern of decrease was seen, from 9.3% (1996) and 9.4% (2006) to 5.7% (2017; P < 0.001). In all three cohorts, AD was more common among girls than boys (18.9% vs. 13.8% in 2017; P < 0.001). Children from the mountain inlands had a higher prevalence of AD than children from coastal cities (22.0% vs. 15.1% in 2017; P < 0.001). In comparing D-AD, there were no significant differences between the sexes or between inland or coastal living. Concomitant asthma increased over the years from 12.2% (1996) to 15.8% (2006) to 23.0% (2017; P < 0.001). Concomitant allergic rhinitis and allergic sensitization increased from 1996 (15.0% and 27.5%) to 2006 (24.7% and 49.5%) but then levelled off until 2017 (21.0% and 46.7%).Conclusions: The prevalence of AD among schoolchildren in Sweden decreased over the study period, whereas atopic comorbidity among children with AD increased. Although a decrease was seen, AD is still common and the increase in atopic comorbidity among children with AD, especially the increase in asthma, is concerning.

(författare) Fecal short chain fatty acids in children living on farms and a link between valeric acid and protection from eczema. 2020 Ingår i: Scientific reports. - : Springer Science and Business Media LLC. - 2045-2322. ; 10:1 Tidskriftsartikel (refereegranskat)abstract Children growing up on farms have low rates of allergy, but the mechanism for this protective effect has not been fully elucidated. Short chain fatty acids (SCFAs) produced by the gut microbiota may play a role in protection from allergy. We measured fecal SCFA levels in samples collected from 28 farming and 37 control children over the first 3years of life using gas chromatography. Data on diet and other host factors were recorded and allergy was diagnosed at 8years of age. Among all children, median propionic and butyric acid concentration increased over the first 3years, and longer SCFAs typically appeared by 1year of age. Farm children had higher levels of iso-butyric, iso-valeric and valeric acid at 3years of age than rural controls. In addition, children with elder siblings had higher levels of valeric acid at 3years of age, and dietary factors also affected SCFA pattern. High levels of valeric acid at 3years of age were associated with low rate of eczema at 8years of age. The fecal SCFA pattern in farm children suggests a more rapid maturation of the gut microbiota. Valeric acid or associated microbes may have protective potential against eczema.

(författare) Low Concentration of Fecal Valeric Acid at 1 Year of Age Is Linked with Eczema and Food Allergy at 13 Years of Age : Findings from a Swedish Birth Cohort 2022 Ingår i: International Archives of Allergy and Immunology. - : S. Karger. - 1018-2438 .- 1423-0097. ; , s. 398-408 Tidskriftsartikel (refereegranskat)abstract Background: Short-chain fatty acids (SCFAs) are abundant bacterial metabolites in the gut, with immunomodulatory properties. Hence, they may influence allergy development. Previous studies have linked fecal SCFA pattern during infancy with allergy. However, the association of SCFAs to allergic outcomes in adolescence is not well established. Here, we examined how the fecal SCFA pattern at 1 year of age related to allergy at 13 years of age.Methods: Levels of 8 SCFAs in fecal samples collected at 1 year of age from 110 children were quantified using gas chromatography. The same individuals were evaluated at 13 years of age for allergic symptoms, allergy diagnosis and allergy medication by questionnaire, and for sensitization using skin prick test against egg, milk, fish, wheat and soy, cat, dog, horse, birch, and timothy grass.Results: The concentration of fecal valeric acid at 1 year of age was inversely associated with eczema at 13 years of age (OR 0.6, 95% CI: 0.4-1.0, p = 0.049) and showed a trend for inverse association with food allergy at 13 years of age (OR 0.6, 95% CI: 0.4-1.0, p = 0.057). In a sub-group analysis of children with eczema at 1 year of age, a higher concentration of fecal valeric acid was linked with reduced risk of their eczema remaining at 13 years of age (OR 0.2, 95% CI: 0.0-1.5), although this latter analysis did not reach statistical significance (p = 0.12).Conclusions: Our findings lend further support to the notion of early childhood as a critical period when allergy may be programmed via the gut microbiota. Higher levels of fecal valeric acid may be characteristic of a protective gut microbiota and/or actively contribute to protection from eczema and food allergy.
46.	Johansson, Joakim, et al. (författare) Dynamics of leukocyte receptors after severe burns: An exploratory study 2011 Ingår i: BURNS. - Oxford : Elsevier Science B.V., Amsterdam.. - 0305-4179 .- 1879-1409. ; 37:2, s. 227-233 Tidskriftsartikel (refereegranskat)abstract Background: Patients with burns are susceptible to organ failure, and there is indirect evidence that leukocytes may contribute to this process. They may change the expression of cell-surface receptors after certain stimuli, for example, the burn. We therefore aimed to assess the changes induced by the burn in the expression of leukocyte cell-surface receptors CD11b, CD14, CD16, and CD62L on the surface of PMNs and monocytes. We also wanted to examine the dynamics of this activation during the first week after the burn, and to relate it to the size of the injury. Methods: Ten patients with burns of andgt;15% (TBSA) were included in the study. Blood samples were collected on arrival and every consecutive morning during the first week. Healthy volunteers acted as controls. Results: PMN CD11b expression was increased. The extent of PMN CD11b expression correlated negatively to the size of the full thickness burn. Monocyte CD14 expression increased initially but there was no relation to the size of the burn. PMN CD16 expression decreased initially during the first days and the decrease was related to burn size. CD62L did not vary depending on the burn in either PMN or monocytes during the first week after the burn. Conclusion: This study showed that specific receptors on the surface of leukocytes (PMN CD11b, monocyte CD14 and PMN CD16) are affected by the burn. Expression of PMN CD11b and CD16 are related to burn size. Burn-induced effects on the expression of PMN receptors, such as PMN CD11b and CD16, may contribute to burn-induced infection susceptibility.

Allergic patients deserve access to the same publicly recommended immunizations as non-allergic patients unless risks associated with vaccination outweigh the gains. Whereas the number of reported possible allergic reactions to vaccines is high, confirmed vaccine-triggered allergic reactions are rare. Anaphylaxis following vaccination is rare, affecting <1/100 000, but can occur in any patient. Some patient groups, notably those with a previous allergic reaction to a vaccine or its components, are at heightened risk of allergic reaction and require special precautions. Allergic reactions, however, may occur in patients without known risk factors and cannot be predicted by currently available tools. Unwarranted fear and uncertainty can result in incomplete vaccination coverage for children and adults with or without allergy. In addition to concerns about an allergic reaction to the vaccine itself, there is fear that routine childhood immunization may promote the development of allergic sensitization and disease. Thus, although there is no evidence that routine childhood immunization increases the risk of allergy development, such risks need to be discussed.

(författare) Asthma and atopic diseases in adolescence and antidepressant medication in middle age 2018 Ingår i: Journal of Health Psychology. - London, United Kingdom : Sage Publications. - 1359-1053 .- 1461-7277. ; 23:6, s. 853-859 Tidskriftsartikel (refereegranskat)abstract This Swedish register-based cohort study examined whether asthma, hay fever and allergic dermatitis in late adolescence identified in the early 1970s are associated with antidepressant medication in middle age, between 2006 and 2009. After adjustment for childhood and adulthood sociodemographic characteristics, psychological, cognitive and physical function, and comorbidity, the magnitude of the associations diminished for asthma, while hay fever and atopic dermatitis retained associations. Hay fever and atopic dermatitis in adolescence have potentially important implications for future mental health, while asthma may already have influenced an individual's ability to cope with stress by late adolescence.

However, nucleic acid amplification tests (NAATs) have rapidly replaced culture for diagnostics in many settings. The aim of the present study was to investigate the appropriate time for test-of-cure (TOC) when NAATs are used for diagnosis of gonorrhoea. In total, 30 patients (28 men and 2 women) provided urethral, cervical, rectal or pharyngeal specimens for TOC. All included patients, except one who did not return for second TOC before day 19, tested negative within 2 weeks after treatment with cefixime 400 mg x 1. Antimicrobial susceptibility testing showed that 68% of the culture-positive strains were resistant to ciprofloxacin. Thus, the recommended empirical treatment with ciprofloxacin in Norway should be changed immediately. TOC can be performed 2 weeks after treatment when NAATs are used for diagnosis of gonorrhoea.

(författare) Near infrared and skin impedance spectroscopy : a possible support in the diagnostic process of skin tumours in primary health care 2015 Ingår i: Skin research and technology. - : John Wiley & Sons. - 0909-752X .- 1600-0846. ; 21:4, s. 493-499 Tidskriftsartikel (refereegranskat)abstract Background/purpose: The global incidence of skin cancer has increased drastically in recent decades, especially in Australia and Northern Europe. Early detection is crucial for good prognosis and high survival rates. In general, primary care physicians have considerably lower sensitivity and specificity rates for detection of skin cancer, compared to dermatologists. A probable main reason for this is that current diagnostic tools are subjective in nature, and therefore diagnostic skills highly depend on experience. Illustratively, in Sweden, approximately 155500 benign skin lesions are excised unnecessarily every year. An objective instrument, added to the clinical examination, might improve the diagnostic accuracy, and thus promote earlier detection of malignant skin tumours, as well as reduce medical costs associated with unnecessary biopsies and excisions. The general aim of this study was to investigate the usefulness of the combination of near infrared (NIR) and skin impedance spectroscopy as a supportive tool in the diagnosis and evaluation of skin tumours in primary health care.Methods: Near infrared and skin impedance data were collected by performing measurements on suspect malignant, premalignant and benign tumours in the skin of patients seeking primary health care for skin tumour evaluation. The obtained data were analysed using multivariate analysis and compared with the diagnosis received by the conventional diagnostic process.Results: The observed sensitivity and specificity rates were both 100%, when discriminating malignant and premalignant skin tumours from benign skin tumours, and the observed sensitivity and specificity for separating malignant skin tumours from premalignant and benign skin tumours were also 100%, respectively.Conclusion: The results of this study indicate that the NIR and skin impedance spectroscopy may be a useful supportive tool for the general practitioner in the diagnosis and evaluation of skin tumours in primary health care, as a complement to the visual assessment.
