1.	Constantinescu, Radu, 1966, et al. (författare) Proteomic profiling of cerebrospinal fluid in parkinsonian disorders. 2010 Ingår i: Parkinsonism & related disorders. - : Elsevier BV. - 1873-5126 .- 1353-8020. ; :16, s. 545-49 Tidskriftsartikel (refereegranskat)abstract Parkinson's disease (PD) and atypical parkinsonian disorders (APD), including multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD), are a group of neurodegenerative diseases sharing many similar signs and symptoms but distinguished by their particular clinical features, treatment response, prognosis and mortality. The differential diagnosis may be challenging, especially in early disease stages. Considering the importance of an accurate diagnosis both for clinical management and for research, new diagnostic tools are needed. In this study, we investigated 56 PD, 42 MSA, 39 PSP, 9 CBD patients, and 24 healthy controls. After screening the cerebrospinal fluid (CSF) proteome using surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS), we identified 4 proteins (ubiquitin [mass-to-charge ratio (m/z) 8590], beta2-microglobulin [m/z 11730], and 2 secretogranin 1 [chromogranin B] fragments [m/z 7260 and m/z 6250]) that differentiated healthy controls and PD patients from patients with APD. However, they could not differentiate PD patients from controls. As none of these changes were APD subgroup-specific, they most likely reflect the intensity and/or extent of the neurodegenerative process in general.

(författare) Thromboembolic events, major bleeding and mortality in essential thrombocythaemia and polycythaemia vera : a matched nationwide population-based study 2024 Ingår i: British Journal of Haematology. - : John Wiley & Sons. - 0007-1048 .- 1365-2141. ; 204:5, s. 1740-1751 Tidskriftsartikel (refereegranskat)abstract Thromboembolic events and bleeding are known complications in essential thrombocythaemia (ET) and polycythaemia vera (PV). Using multiple Swedish health care registers, we assessed the rate of arterial and venous events, major bleeding, all-cause stroke and all-cause mortality in ET and PV compared to matched controls. For each patient with ET (n = 3141) and PV (n = 2604), five matched controls were randomly selected. In total, 327 and 405 arterial or venous events were seen in the group of ET and PV patients respectively. Compared to corresponding controls, the rate of venous thromboembolism, major bleeding and all-cause mortality per 100 treatment years was significantly increased among both ET (0.63, 0.79 and 3.70) and PV patients (0.94, 1.20 and 4.80). The PV patients also displayed a significantly higher rate of arterial events and all-cause stroke compared to controls. When dividing the cohort into age groups, we found a significantly higher rate of arterial and venous events in all age groups of PV patients, and the rate of all-cause mortality was significantly higher in both ET and PV patients in all ages above the age of 50. This study confirms that PV and ET are diseases truly marked by thromboembolic complications and bleeding.

(författare) Impact of asthma medication and familial factors on the association between childhood asthma and attention-deficit/hyperactivity disorder: a combined twin- and register-based study 2015 Ingår i: Clinical and Experimental Allergy. - Stockholm : Wiley. - 0954-7894 .- 1365-2222. ; 45:5, s. 964-973 Tidskriftsartikel (refereegranskat)abstract BackgroundAsthma and attention-deficit/hyperactivity disorder (ADHD) are prevalent in childhood and may cause functional impairment and stress in families. Previous research supports an association between asthma and ADHD in children, but several aspects of this relationship are unclear. ObjectiveOur aim was to study whether the association between asthma and ADHD is restricted to either the inattentive or the hyperactive/impulsive symptoms of ADHD, to explore the impact of asthma severity and asthma medication and the contribution of shared genetic and environmental risk factors on the asthma-ADHD relationship. MethodsData on asthma, ADHD, zygosity and possible confounders were collected from parental questionnaires at 9 or 12years on 20072 twins through the Swedish Twin Register, linked to the Swedish Medical Birth Register, the National Patient Register and the Prescribed Drug Register. The association between asthma and ADHD, the impact of asthma severity and medication, was assessed by generalized estimating equations. Cross-twin-cross-trait correlations (CTCT) were estimated to explore the relative importance of genes and environment for the association. ResultsAsthmatic children had a higher risk of also having ADHD [odds ratio (OR) 1.53, 95% confidence interval (CI): 1.16-2.02]. The association was not restricted to either of the two dimensions of ADHD. The magnitude of the association increased with asthma severity (OR 2.84, 95% CI: 1.86-4.35) for 4 asthma attacks in the last 12months and was not affected by asthma treatment. The CTCTs possibly indicate that the genetic component in overlap of the disorders is weak. Conclusions and Clinical RelevanceChildhood asthma, especially severe asthma, is associated with ADHD. Asthma medication seems not to increase the risk of ADHD. Clinicians should be aware of the potential of ADHD in asthma. Optimal asthma care needs to be integrated with effective evaluation and treatment of ADHD in children with co-existing disorders.

(författare) Somatic deletions in hereditary breast cancers implicate 13q21 as a putative novel breast cancer susceptibility locus 2000 Ingår i: Proceedings of the National Academy of Sciences. - 1091-6490. ; 97:17, s. 9603-9608 Tidskriftsartikel (refereegranskat)abstract A significant proportion of familial breast cancers cannot be explained by mutations in the BRCA1 or BRCA2 genes. We applied a strategy to identify predisposition loci for breast cancer by using mathematical models to identify early somatic genetic deletions in tumor tissues followed by targeted linkage analysis. Comparative genomic hybridization was used to study 61 breast tumors from 37 breast cancer families with no identified BRCA1 or BRCA2 mutations. Branching and phylogenetic tree models predicted that loss of 13q was one of the earliest genetic events in hereditary cancers. In a Swedish family with five breast cancer cases, all analyzed tumors showed distinct 13q deletions, with the minimal region of loss at 13q21-q22. Genotyping revealed segregation of a shared 13q21 germ-line haplotype in the family. Targeted linkage analysis was carried out in a set of 77 Finnish, Icelandic, and Swedish breast cancer families with no detected BRCA1 and BRCA2 mutations. A maximum parametric two-point logarithm of odds score of 2.76 was obtained for a marker at 13q21 (D13S1308, theta = 0.10). The multipoint logarithm of odds score under heterogeneity was 3.46. The results were further evaluated by simulation to assess the probability of obtaining significant evidence in favor of linkage by chance as well as to take into account the possible influence of the BRCA2 locus, located at a recombination fraction of 0.25 from the new locus. The simulation substantiated the evidence of linkage at D13S1308 (P < 0.0017). The results warrant studies of this putative breast cancer predisposition locus in other populations.

The QA round involved blinded genotyping of 47 DNA samples for 18 or six randomly selected SNPs. The methods used by the participating laboratories included all major platforms for small- to medium-size SNP genotyping. The laboratories used their standard procedures for SNP assay design, genotyping, and quality control. Based on the joint results from all laboratories, a consensus genotype for each DNA sample and SNP was determined by the coordinator of the survey, and the results from each laboratory were compared to this genotype. The overall genotyping accuracy achieved in the survey was excellent. Six laboratories delivered genotype data that were in full agreement with the consensus genotype. The average accuracy per SNP varied from 99.1 to 100% between the laboratories, and it was frequently 100% for the majority of the assays for which SNP genotypes were reported. Lessons from the survey are that special attention should be given to the quality of the DNA samples prior to genotyping, and that a conservative approach for calling the genotypes should be used to achieve a high accuracy.

When an area spans such a large diversity of research, and where research from many different countries is also involved, a review of these developments becomes especially useful. Because it bridges science and technology the field also provides a desired interaction between researchers and research in technologically advanced and developing countries. The present series of volumes, "The Encyclopedia of Sensors" , the first of its kind, is intended to provide a timely compendium of the entire field. As such it can be expected to play a significant role in worldwide future progress and understanding."

8.	Welander, Frida, et al. (författare) Direct oral anticoagulants versus warfarin in patients with non-valvular atrial fibrillation and CKD G3-G5D 2023 Ingår i: Clinical Kidney Journal. - : Oxford University Press. - 2048-8505 .- 2048-8513. ; 16:5, s. 835-844 Tidskriftsartikel (refereegranskat)abstract Background: The use of direct oral anticoagulants (DOAC) in patients with non-valvular atrial fibrillation (NVAF) and advanced chronic kidney disease (CKD) including dialysis is growing. Several studies have shown favorable results of DOAC compared with warfarin regarding bleeding risk but no difference in stroke protection. However, these studies had poor time in therapeutic range (TTR), in the warfarin comparison group.Methods: This was a Swedish national cohort study investigating the risk of ischemic stroke and major bleeding on DOAC compared with warfarin in patients with NVAF, glomerular filtration rate category 3-5D (G3-G5D), kidney transplant recipients excluded, between 2009 and 2018. Data extracted from high-quality national healthcare registries including the Swedish Renal Registry, AuriculA (the Swedish national quality register for AF and anticoagulation) and The Stroke Register.Results: At enrolment, of 2453 patients 59% were treated with warfarin (mean TTR 67%) and 41% with DOAC. Overall, 693 (28.3%) had G3, 1113 (45.4%) G4, 222 (9.1%) G5 and 425 (17.3%) G5D. DOAC compared with warfarin showed lower hazard of major bleeding [hazard ratio 0.71 (95% confidence interval 0.53-0.96)] but no difference in ischemic stroke risk. Mortality was increased during DOAC treatment [1.24 (1.01-1.53)], presumably not a causal association since fewer fatal bleedings occurred on DOAC.Conclusions: DOAC treatment, compared with warfarin, is associated with almost 30% lower risk of bleeding in patients with NVAF and CKD G3-G5D. The stroke risk is comparable between the treatments. This is the first study comparing DOAC and well-managed warfarin (TTR 67%) in advanced CKD. Ongoing and planned randomized controlled trials need to confirm the possible benefit of DOAC.
9.	Welander, Frida, et al. (författare) Efficacy and safety of warfarin in patients with non-valvular atrial fibrillation and CKD G3-G5D 2022 Ingår i: Clinical Kidney Journal. - : Oxford University Press. - 2048-8505 .- 2048-8513. ; 15:6, s. 1169-1178 Tidskriftsartikel (refereegranskat)abstract Background: Observational data comparing warfarin with no treatment for patients with non-valvular atrial fibrillation (NVAF) and severely reduced glomerular filtration rate (GFR) are conflicting and randomized controlled trials (RCTs) are lacking. Most studies do not provide information on warfarin treatment quality, making them difficult to compare.Methods: This national cohort study investigates the risk of ischaemic stroke and major bleeding during warfarin treatment compared with no oral anticoagulants in patients with NVAF, GFR category 3-5 (G3-G5) or on dialysis (G5D), with kidney transplant recipients excluded, between 2009 and 2018. Data extracted from high-quality Swedish national healthcare registries, including the Swedish Renal Registry, AuriculA-the Swedish national quality registry for atrial fibrillation and anticoagulation- A nd the Stroke Registry.Results: At enrolment of 12 106 patients, 21.4% were G3, 43.5% were G4, 11.6% were G5 and 23.6% were G5D. The mean time in the therapeutic range was 70%. Warfarin compared with no treatment showed a lower risk for ischaemic stroke for G3 {hazard ratio [HR] 0.37 [95% confidence interval (CI) 0.18-0.76]}, G4 [0.53 (0.38-0.74)] and G5 [0.49 (0.30-0.79)] and an increased risk of major bleeding in G4 [HR 1.22 (1.02-1.46)], G5 [1.52 (1.15-2.01)] and G5D [1.23 (1.00-1.51)]. All-cause mortality was more than halved on warfarin compared with no treatment in all GFR categories.Conclusions: Warfarin treatment is associated with a lower risk of ischaemic stroke for patients with NVAF and G3, G4 and G5D at the cost of a higher risk of major bleeding for G4-G5D. Existing observational data are conflicting, stressing the need for RCTs on warfarin compared with no treatment in G4-G5D. Awaiting RCTs, it seems reasonable to treat selected patients on dialysis and NVAF with warfarin.

(författare) Warfarin treatment quality and outcomes in patients with non-valvular atrial fibrillation and CKD G3-G5D 2023 Ingår i: Thrombosis Research. - : Elsevier. - 0049-3848 .- 1879-2472. ; 229, s. 131-138 Tidskriftsartikel (refereegranskat)abstract Introduction: Warfarin treatment quality is calculated as time in therapeutic range (TTR). TTR ≥ 70 % is considered reducing the risk of adverse events for patients with atrial fibrillation (AF). The association of TTR and adverse events in chronic kidney disease (CKD) is however poorly investigated. The aim is to explore this further.Materials and methods: Swedish cohort study based on national healthcare registers between 2009 and 2018, including Swedish Renal Registry, Swedish Stroke Register and AuriculA - the Swedish national quality register for AF and anticoagulation. Investigating the effect of individual TTR (iTTR) and iTTR ≥ 70 % versus <70 % on the risk of ischemic stroke, major bleeding and death for patients with CKD GFR category 3–5 (G3-G5) including patients on dialysis (G5D) and non-valvular AF (NVAF).Results: Of 2379 included patients 21.9 % had G3, 47.5 % G4, 10.8 % G5 and 19.8 % G5D. TTR in G3 was 75.6 %, G4 72.2 %, G5 67.6 % and G5D 62.0 %. Increase by 10 percentage points iTTR conferred lower risk of major bleeding, ischemic stroke and death for all patients (hazard ratio 0.91 (95 % Confidence interval 0.87–0.94), 0.92 (0.85–0.99) and 0.88 (0.85–0.90)). iTTR≥ 70 % versus <70 % was associated with lower risk of bleeding and death in all patients (0.63 (0.51–0.77) and (0.51 (0.43–0.61)), and a non-significant tendency towards lower stroke risk (0.67 (0.43–1.06)).Conclusions: Warfarin treatment quality worsens with decreasing GFR. Higher iTTR confers lower risk of bleeding, ischemic stroke and death in patients with NVAF and G3-G5D. iTTR ≥ 70 % was associated with better safety profile. Close monitoring of patients with CKD on warfarin is recommended.
11.	Ahlford, Marianne, et al. (författare) Uppsala Underdogs - A Robot Soccer Project 2006 Rapport (populärvet., debatt m.m.)abstract In this paper, we describe the four-legged soccer team Uppsala Underdogs developed by a group of 4th year computer science students at Uppsala University during the fall of 2004. The project is based on the experience from two similar previous projects. This year the emphasis of the project has been on distribution of data and on support for evaluation and reconfiguration of strategies. To support data distribution, a middleware has been developed, which implements a replication algorithm and provides a clean interface for the other software modules (or behaviors). To enable easy reconfiguration of strategies, an automata-based graphical description language has been developed, which can be compiled into code that uses the database and the lower level modules, such as tactics and positioning, to make decisions and control the robot. In addition, a graphical simulator has been developed in which the strategies can be evaluated.

(författare) Acute coronary syndrome in relation to the occurrence of associated symptoms : A quantitative study in prehospital emergency care. 2017 Ingår i: International Emergency Nursing. - : Elsevier BV. - 1755-599X .- 1878-013X. ; 33, s. 43-47 Tidskriftsartikel (refereegranskat)abstract INTRODUCTION: Acute chest pain is a common symptom among prehospital emergency care patients. Therefore, it is crucial that ambulance nurses (ANs) have the ability to identify symptoms and assess patients suffering from acute coronary syndrome (ACS). The aim of this study is to explore the occurrence of dyspnoea and nausea and/or vomiting in the prehospital phase of a suspected ACS and the associations with patients' outcome.METHODS: This study has a quantitative design based on data from hospital records and from a previous interventional study (randomised controlled trial) including five Emergency Medical Service (EMS) systems in western Sweden in the years 2008-2010.RESULTS: In all, 1836 patients were included in the interventional study. Dyspnoea was reported in 38% and nausea and/or vomiting in 26% of patients. The risk of death within one year increased with the presence of dyspnoea. The presence of nausea and/or vomiting increased the likelihood of a final diagnosis of acute myocardial infarction (AMI).CONCLUSION: This study shows that dyspnoea, nausea and/or vomiting increase the risk of death and serious diagnosis among ACS patients. This means that dyspnoea, nausea and/or vomiting should influence the ANs' assessment and that special education in cardiovascular nursing is required.

The aim of this study was to identify competency requirements for the assessment of patients with mental illness by soliciting the views of emergency care nurses. A modified Delphi method comprising four rounds was used. Data were collected in Sweden between October 2018 and March 2019. The data were analyzed using content analysis and descriptive statistics. The panel of experts reached the highest level of consensus regarding basic medical knowledge: the capability to listen and show respect to the patient are essential competency requirements when assessing patients with mental illness in emergency care. Awareness of these competency requirements will enhance teaching and training of emergency care nurses.

(författare) Ethics education to support ethical competence learning in healthcare : an integrative systematic review 2022 Ingår i: BMC Medical Ethics. - : BioMed Central. - 1472-6939. ; 23 Forskningsöversikt (refereegranskat)abstract Background: Ethical problems in everyday healthcare work emerge for many reasons and constitute threats to ethi- cal values. If these threats are not managed appropriately, there is a risk that the patient may be inflicted with moral harm or injury, while healthcare professionals are at risk of feeling moral distress. Therefore, it is essential to support the learning and development of ethical competencies among healthcare professionals and students. The aim of this study was to explore the available literature regarding ethics education that promotes ethical competence learning for healthcare professionals and students undergoing training in healthcare professions.Methods: In this integrative systematic review, literature was searched within the PubMed, CINAHL, and PsycInfo databases using the search terms ‘health personnel’, ‘students’, ‘ethics’, ‘moral’, ‘simulation’, and ‘teaching’. In total, 40 arti- cles were selected for review. These articles included professionals from various healthcare professions and students who trained in these professions as subjects. The articles described participation in various forms of ethics education. Data were extracted and synthesised using thematic analysis.Results: The review identified the need for support to make ethical competence learning possible, which in the long run was considered to promote the ability to manage ethical problems. Ethical competence learning was found to be helpful to healthcare professionals and students in drawing attention to ethical problems that they were not previ- ously aware of. Dealing with ethical problems is primarily about reasoning about what is right and in the patient’s best interests, along with making decisions about what needs to be done in a specific situation.Conclusions: The review identified different designs and course content for ethics education to support ethical competence learning. The findings could be used to develop healthcare professionals’ and students’ readiness and capabilities to recognise as well as to respond appropriately to ethically problematic work situations.

(författare) SiC-FE gas sensor based combustion control in domestic heating systems, characteristics and utility 2007 Annan publikation (övrigt vetenskapligt/konstnärligt)abstract SiC based field effect gas sensors have been evaluated for future possible use in combustion control schemes for domestic heating systems. Emphasis has been on the possibility to monitor the state of combustion and follow the development of the combustion process from an emissions point of view and to determine its cause. The sensor signals have been compared to true emissions data – CO and total hydrocarbon concentration – as obtained by an IR spectrometer and a flame ionization detector (FID) as well as flue gas concentration of oxygen as obtained by a paramagnetic cell. The sensor characteristics have been evaluated using multivariate statistics and the results suggest that, by using the signals from one or more SiC-based field effect sensors and a thermocouple, it seems possible to provide a rough picture of the state of combustion applicable to a control scheme in order to reduce emissions and increase the power to fuel economy.

Despite geographic proximity, Swedish surgeons distinctively favour TEP, whereas Danish surgeons prefer TAPP. The aim of this study is to analyse the risk of reoperation for recurrence after TAPP, TEP and Lichtenstein repair using data from two nationwide registers. We also aim to discuss advantages of international collaboration between nationwide registers.METHODS: All groin hernia operations registered as TEP, TAPP or Lichtenstein repair in the Swedish Hernia Register and the Danish Hernia Database between January 2004 and December 2020 will be included. Cumulative hazard rate of reoperation for recurrence will be estimated using Cox-regression analyses adjusted for age and anatomy.CONCLUSION: Approximately 400,000 operations are estimated to have been registered prospectively in the inclusion period in the registers. The merging of two nationwide registers was made possible owing to close cooperation between the register steering committees and by obtaining the necessary approvals. This unique collaboration between nationwide registers will make it possible to compare the risk of reoperation for recurrence after TAPP, TEP and Lichtenstein repair on an international level. In future, similar collaboration may be established to explore other outcomes such as complication rates and chronic pain.

19.	Arthur, Rhonda, et al. (författare) Association between baseline serum glucose, triglycerides and total cholesterol, and prostate cancer risk categories 2016 Ingår i: Cancer Medicine. - : Wiley. - 2045-7634. ; 5:6, s. 1307-1318 Tidskriftsartikel (refereegranskat)abstract Lifestyle-related risk factors such as hyperglycemia and dyslipidemia have been associated with several cancers. However, studies exploring their link with prostate cancer (PCa) clinicopathological characteristics are sparse and inconclusive. Here, we investigated the associations between serum metabolic markers and PCa clinicopathological characteristics. The study comprised 14,294 men from the Swedish Apolipoprotein MOrtality RISk (AMORIS) cohort who were diagnosed with PCa between 1996 and 2011. Univariate and multivariable logistic regression were used to investigate the relation between glucose, triglycerides and total cholesterol and PCa risk categories, PSA, Gleason score, and T-stage. Mean age at time of PCa diagnosis was 69 years. Men with glucose levels >6.9 mmol/L tend to have PSA<4 mu g/L, while those with glucose levels of 5.6-6.9 mmol/L had a greater odds of PSA>20 mu g/L compared to PSA 4.0-9.9 mu g/L. Hypertriglyceridemia was also positively associated with PSA>20 mu g/L. Hyperglycemic men had a greater odds of intermediate-and high-grade PCa and advanced stage or metastatic PCa. Similarly, hypertriglyceridemia was positively associated with high-grade PCa. There was also a trend toward an increased odds of intermediate risk localized PCa and advanced stage PCa among men with hypertriglyceridemia. Total cholesterol did not have any statistically significant association with any of the outcomes studied. Our findings suggest that high serum levels of glucose and triglycerides may influence PCa aggressiveness and severity. Further investigation on the role of markers of glucose and lipid metabolism in influencing PCa aggressiveness and severity is needed as this may help define important targets for intervention.

(författare) Serum glucose, triglycerides, and cholesterol in relation to prostate cancer death in the Swedish AMORIS study 2019 Ingår i: Cancer Causes and Control. - : Springer. - 0957-5243 .- 1573-7225. ; 30:2, s. 195-206 Tidskriftsartikel (refereegranskat)abstract Purpose: Lifestyle-related conditions such as obesity are associated with prostate cancer progression, but the associations with hyperglycemia and dyslipidemia are unclear. This study, therefore, aims to examine the association of glucose, triglycerides, and total cholesterol with prostate cancer death. Methods: From the Swedish AMORIS cohort, we selected 14,150 men diagnosed with prostate cancer between 1996 and 2011 who had prediagnostic measurements of serum glucose, triglycerides, and total cholesterol. Multivariable Cox proportional hazards regressionmodels were used to determine the hazard ratios for death in relation to the aforementioned metabolic markers. Results: Using clinical cut-off points, a non-significant positive association was observed between glucose and prostate cancer death. When compared to those with glucose in the lowest quartile, those in the highest quartile had greater risk of prostate cancer death (HR 1.19; 95% CI 1.02-1.39). However, neither total cholesterol nor triglycerides were associated with prostate cancer death. Glucose and triglycerides were positively associated with overall, cardiovascular, and other deaths. Hypercholesterolemia was only associated with risk of CVD death. Conclusion: Our results suggest that glucose levels may influence prostate cancer survival, but further studies using repeated measurements are needed to further elucidate how glucose levels may influence prostate cancer progression.

Self-gripping mesh was developed to decrease the risk for development of chronic pain. The aim of this nationwide cohort study was to compare recurrence rate and chronic pain 1 year after an open, anterior mesh repair of inguinal hernias with either a self-gripping mesh or other lightweight mesh. Method: All operations registered as open anterior mesh repair (Lichtenstein) in the Swedish Hernia Registry between September 2012 and October 2016 were selected. At 1 year after repair, patients were sent a pain questionnaire assessing chronic pain. We compared the prevalence of chronic pain and reoperation for recurrence using lightweight, sutured mesh or self-gripping mesh. Results: We analyzed the 1,803 repairs using self-gripping mesh and 16,567 repairs using lightweight mesh. We found no difference in the prevalence of chronic pain 1 year after the hernia repair between selfgripping mesh and sutured lightweight mesh (OR 0.92, CI 95% 0.80-1.06, P = .257). There was no increase in reoperation for recurrence when using self-gripping mesh (HR 0.71, CI 95% 0.45-1.14, P = .156). Mean operation time was considerably less when using self-gripping mesh (43 vs 70 minutes; P > .001). Conclusion: The use of self-gripping mesh does not decrease the incidence of chronic pain and reoperation for recurrence compared with lightweight, sutured mesh for open anterior mesh repair of inguinal hernias. Furthermore, the use of self-gripping mesh is associated with a clinically important, lesser operation time. (C) 2019 Elsevier Inc. All rights reserved.

(författare) Social differences in lung cancer management and survival in South East England : a cohort study 2012 Ingår i: BMJ Open. - : BMJ. - 2044-6055. ; 2:3, s. e001048- Tidskriftsartikel (refereegranskat)abstract OBJECTIVE:To examine possible social variations in lung cancer survival and assess if any such gradients can be attributed to social differences in comorbidity, stage at diagnosis or treatment.DESIGN:Population-based cohort identified in the Thames Cancer Registry.SETTING:South East England.PARTICIPANTS:15 582 lung cancer patients diagnosed between 2006 and 2008.MAIN OUTCOME MEASURES:Stage at diagnosis, surgery, radiotherapy, chemotherapy and survival.RESULTS:The likelihood of being diagnosed as having early-stage disease did not vary by socioeconomic quintiles (p=0.58). In early-stage non-small-cell lung cancer, the likelihood of undergoing surgery was lowest in the most deprived group. There were no socioeconomic differences in the likelihood of receiving radiotherapy in stage III disease, while in advanced disease and in small-cell lung cancer, receipt of chemotherapy differed over socioeconomic quintiles (p<0.01). In early-stage disease and following adjustment for confounders, the HR between the most deprived and the most affluent group was 1.24 (95% CI 0.98 to 1.56). Corresponding estimates in stage III and advanced disease or small-cell lung cancer were 1.16 (95% CI 1.01 to 1.34) and 1.12 (95% CI 1.05 to 1.20), respectively. In early-stage disease, the crude HR between the most deprived and the most affluent group was approximately 1.4 and constant through follow-up, while in patients with advanced disease or small-cell lung cancer, no difference was detectable after 3 months.CONCLUSION:We observed socioeconomic variations in management and survival in patients diagnosed as having lung cancer in South East England between 2006 and 2008, differences which could not fully be explained by social differences in stage at diagnosis, co-morbidity and treatment. The survival observed in the most affluent group should set the target for what is achievable for all lung cancer patients, managed in the same healthcare system.

(författare) Melphalan 100mg/m(2) with stem cell support as first relapse treatment is safe and effective for myeloma patients with long remission after autologous stem cell transplantation. 2011 Ingår i: European journal of haematology. - : Wiley. - 1600-0609 .- 0902-4441. ; 87:2, s. 117-22 Tidskriftsartikel (refereegranskat)abstract Introduction: Today, a number of therapeutic options are available as the patient with myeloma relapses from initial treatment with high-dose melphalan and autologous stem cell transplantation (ASCT). For patients who experience a durable response to primary ASCT, retreatment with high-dose melphalan is recommended by many current guidelines. Yet, toxicity is an important aspect in the choice of relapse treatment, and a second ASCT in this setting could be associated with enhanced toxicity. As the goal for the treatment for relapsed myeloma should be disease control while maintaining quality of life, lower doses of melphalan might be preferable. Methods and Objectives: In this retrospective study, we account for the outcome of 66 patients with myeloma in first systemic relapse after ASCT, who were treated with intermediate-dose melphalan, 100mg/m(2) , and stem cell support (MEL 100). The aim was to evaluate this treatment in relation to prior response duration after initial ASCT and with respect to response rate, toxicity and survival. Results: The overall response rate was 62%. There was limited, mostly haematological, toxicity, and no treatment-related mortality was observed. The median progression-free survival (PFS) was 8.5months, and the median overall survival was 24months. Patients with time to progression of 34months or more (n=17; ≥75th percentile) after initial ASCT had a median PFS of 12.5months after MEL 100. Conclusion: For patients with a long-lasting response after ASCT, MEL 100 could be a therapeutic option with low toxicity and with efficacy comparable to newer immunomodulatory drugs.

To estimate the risk of bacterial and viral infections in multiple myeloma patients, we used population-based data from Sweden to identify all multiple myeloma patients (n=9253) diagnosed from 1988 to 2004 with follow up to 2007 and 34,931 matched controls. Cox proportional hazard models were used to estimate the risk of infections. Overall, multiple myeloma patients had a 7-fold (hazard ratio =7.1; 95% confidence interval = 6.8-7.4) risk of developing any infection compared to matched controls. The increased risk of developing a bacterial infection was 7-fold (7.1; 6.8-7.4), and for viral infections 10-fold (10.0; 8.9-11.4). Multiple myeloma patients diagnosed in the more recent calendar periods had significantly higher risk of infections compared to controls (P<0.001). At one year of follow up, infection was the underlying cause in 22% of deaths in multiple myeloma patients. Mortality due to infections remained constant during the study period. Our findings confirm that infections represent a major threat to multiple myeloma patients. The effect on infectious complications due to novel drugs introduced in the treatment of multiple myeloma needs to be established and trials on prophylactic measures are needed.

The main purpose of the present study was to investigate the association between the exposure BMI at the time of a prostate cancer diagnosis and weight change after diagnosis, and the outcomes of prostate cancer progression and mortality in a large cohort study. Data from 4,376 men diagnosed with clinically localized prostate cancer between 1997 and 2002 were analyzed. BMI and weight change were self-reported in 2007. Hazard ratios (HRs) with 95 % confidence intervals (CIs) were estimated in complete-case analysis (n = 3,214) using Cox proportional hazards models. Progression was experienced among 639 (14.6 %) of the study participants, and in total, 450 (10.3 %) deaths of any cause and 134 (3.1 %) prostate cancer-specific deaths were recorded during follow-up. Obese men had a 47 % increased rate of overall mortality compared to normal weight men (HR 1.47, 95 % CI 1.03-2.10). No statistically significant associations were found for BMI and prostate cancer progression or prostate cancer-specific mortality. A weight loss > 5 % after diagnosis almost doubled the rate of overall mortality compared to maintaining a stable weight (HR 1.94, 95 % CI 1.41-2.66), while a weight gain > 5 % was associated with an almost doubled increased rate of prostate cancer-specific mortality (HR 1.93, 95 % CI 1.18-3.16). Being obese was associated with an increased rate of overall mortality, and gaining weight after a prostate cancer diagnosis was associated with an increased rate of prostate cancer-specific mortality.

The aim of this study was to investigate the effect of physical activity after a prostate cancer diagnosis on both overall and prostate cancer-specific mortality in a large cohort. Methods: Data from 4,623 men diagnosed with localized prostate cancer 1997-2002 and followed-up until 2012 were analyzed. HRs with 95% confidence intervals (CI) were estimated using Cox proportional hazards models to examine the association between post-diagnosis recreational MET-h/d, time spent walking/bicycling, performing household work or exercising, and time to overall and prostate cancer-specific death. All models were adjusted for potential confounders. Results: During the follow-up, 561 deaths of any cause and 194 deaths from prostate cancer occurred. Statistically significantly lower overall mortality rates were found among men engaged in 5 recreationalMET-h/d (HR, 0.63; 95% CI, 0.52-0.77), walking/ bicycling 20 min/d (HR, 0.70; 95% CI, 0.57-0.86), performing householdwork > 1 h/d (HR, 0.71; 95% CI, 0.59-0.86), or exercising > 1 h/wk (HR, 0.74; 95% CI, 0.61-0.90), compared with less active men within each activity type. For prostate cancer-specific mortality, statistically significantly lower mortality rates were seen among men walking/bicycling >= 20 min/d (HR, 0.61; 95% CI, 0.43-0.87) or exercising 1 h/wk (HR, 0.68; 95% CI, 0.48-0.94). Conclusions: Higher levels of physical activity were associated with reduced rates of overall and prostate cancer-specific mortality. Impact: Our study further strengthens previous results indicating beneficial effects of physical activity on survival among men with prostate cancer. Cancer Epidemiol Biomarkers Prev; 24(1); 57-64.

Participants were randomized to a high-intensity functional exercise program or a non-exercise control activity conducted 45 min every other weekday for 4 months. The 15-item Geriatric Depression Scale (GDS) and the Montgomery-Åsberg Depression Rating Scale (MADRS) were administered by blinded assessors at baseline, 4, and 7 months.RESULTS: No difference between the exercise and control activity was found in GDS or MADRS score at 4 or 7 months. Among participants with GDS scores ≥ 5, reductions in GDS score were observed in the exercise and control groups at 4 months (-1.58, P = 0.001 and -1.54, P = 0.004) and 7 months (-1.25, P = 0.01 and -1.45, P = 0.007). Among participants with MADRS scores ≥ 7, a reduction in MADRS score was observed at 4 months in the control group (-2.80, P = 0.009) and at 7 months in the exercise and control groups (-3.17, P = 0.003 and -3.34, P = 0.002).CONCLUSIONS: A 4-month high-intensity functional exercise program has no superior effect on depressive symptoms relative to a control activity among older people with dementia living in residential care facilities. Exercise and non-exercise group activities may reduce high levels of depressive symptoms.

The aim of this study was to determine the background of such differences in Denmark, Iceland and Sweden. Material and methods: Patients with prostate cancer were identified through population-based cancer registers in the three countries. Clinical findings at diagnosis were retrieved from hospital records. In Sweden, clinical information was gathered from regional population-based prostate cancer registers. Country-specific incidence and excess mortality rates were compared, with adjustment for prognostic factors. Results: The relative survival in the cohorts was comparable to that in previous population-based studies. Significant differences in excess mortality rates were found across countries, which diminished or disappeared after adjustment for patient characteristics, i.e. metastatic status, clinical T stage and prostate-specific antigen level. A difference in the proportion of patients with metastatic disease was the main explanation of the differences in survival among countries, while the incidence rates of metastatic cancer were similar. Discussion: Register-based studies of the relative survival of prostate cancer patients are influenced by national differences in clinical presentation at diagnosis. Differences in the proportion of patients with metastatic spread explained most of the difference in relative survival among patients in Denmark, Iceland and Sweden. Future country comparisons of relative survival should include adjustment for differences in patient characteristics, such as stage, prostate-specific antigen level and screening intensity.

A plethora of recent research has reported on these comorbidities and progress has been made in understanding the mechanisms for comorbidity. The goal of this review was to assess the most recent evidence (2016-2021) on the extent of common comorbidities (obesity, depression and anxiety, neurodevelopmental disorders, sleep disorders and autoimmune diseases) and the latest mechanistic research, highlighting knowledge gaps requiring further investigation. We found that the majority of recent studies from around the world demonstrate that children with asthma are at an increased risk of having at least one of the studied comorbidities. A range of potential mechanisms were identified including common early life risk factors, common genetic factors, causal relationships, asthma medication and embryologic origins. Studies varied in their selection of population, asthma definition and outcome definitions. Next, steps in future studies should include using objective measures of asthma, such as lung function and immunological data, as well as investigating asthma phenotypes and endotypes. Larger complex genetic analyses are needed, including genome-wide association studies, gene expression-functional as well as pathway analyses or Mendelian randomization techniques; and identification of gene-environment interactions, such as epi-genetic studies or twin analyses, including omics and early life exposure data. Importantly, research should have relevance to clinical and public health translation including clinical practice, asthma management guidelines and intervention studies aimed at reducing comorbidities.

Male patients operated on with a Lichtenstein repair for a primary direct or indirect inguinal hernia and with a TEP for a later recurrence, with both operations recorded in the Swedish Hernia Register (SHR), were included in the study. The study period was 1994-2014. Under the study period, 130,037 male patients with a primary indirect or direct inguinal hernia were operated on with a Lichtenstein repair. A second operation in the SHR was registered in 2236 of these patients (reoperation rate 1.7 %). TEP was the chosen operation in 737 in this latter cohort. The most likely location for a recurrence was the same as the primary location. If the recurrences change location from the primary place, we recognized that direct hernias had a RR of 1.51 to having a recurrent indirect hernia compared to having a direct recurrence after an indirect primary hernia repair. Recurrent hernias after Lichtenstein are more common on the same location as the primary one, compared to changing the location.

The framework is built on the concept of simplicity without reduction. Out of respect for complexity we designed it to provide a compass, a guide for strategic direction. The framework consists of a backcasting planning process for sustainable development based on four principles (system conditions) for sustainability. The framework does not prescribe detailed actions. Once an organization understands the framework it identifies and specifies the detailed means by which to achieve the strategy, because it knows its business best. The steps in the planning process are understanding and discussing the system conditions for sustainability, describing and discussing how the company relates to the system conditions in today's situation, creating a vision of how the company will fulfill its customers' needs in the futur e while complying with the system conditions, and specifying a program of actions that will take the company from today's situation to the future vision.

In the statistical computing environment R, there are a few packages that estimate models of this kind. The packagelme4 is a de facto standard for mixed effects models. The packageglmmML allows non-normal distributions in the specification of random intercepts. It also allows for the estimation of a fixed effects model, assuming that all cluster intercepts are distinct fixed parameters; moreover, a bootstrapping technique is implemented to replace asymptotic analysis. The random intercepts model is fitted using a maximum likelihood estimator with adaptive Gauss–Hermite and Laplace quadrature approximations of the likelihood function. The fixed effects model is fitted through a profiling approach, which is necessary when the number of clusters is large. In a simulation study, the two approaches are compared. The fixed effects model has severe bias when the mixed effects variance is positive and the number of clusters is large.

This Sustainability Product Analysis (SPA) matrix has conditions for sustainability along one axis and the life cycle of the product along the other axis. The SPA-matrix is used in the ABCD-analysis, which in turn is used in the IPDM. Integrating the tools in this way and using overall conditions for sustainability is unique compared to many other tools and methods for design for the environment. The MSPD is being developed in discussions with ten small- and medium sized enterprises.

The underlying cause of death was taken from the death certificate. Uptake of PSA screening was low in the UK during the period studied. We examined the relationship between cause of death and patient characteristics at diagnosis including age, cancer stage, and treatment (≤6 months of diagnosis).RESULTS: In all, 20,181 deaths occurred during the period; 49.8% recorded as being due to prostate cancer, 17·8% to cardiovascular disease, 11·6% to other cancers, and 20·7% to other causes. Irrespective of age, cancer stage, or treatment ≤6 months of diagnosis, prostate cancer was an important cause of death ranging from 31·6% to 74·3% of all deaths in different subgroups.CONCLUSION: For men with prostate cancer diagnosed in a setting where uptake of PSA screening is low, our findings challenge the belief that prostate cancer is not an important cause of death.

The initial differential diagnosis can be extremely challenging with major implications for prognosis. The 42 amino acid fragment of amyloid-beta (Abeta42), neurofilament light chain (NFL), neurofilament heavy chain (pNFH), tau protein, glial fibrillary acidic protein (GFAP), neuron specific enolase (NSE), S-100B protein, and myelin basic protein (MBP) are brain related proteins (BRP) present in neurons and glia cells. They are released in the cerebrospinal fluid (CSF) after brain tissue damage caused by a variety of neurological diseases, including the parkinsonian disorders. A review of the literature shows that, carefully interpreted, the CSF levels of BRP can be of value in the differential diagnosis of parkinsonian disorders.

Objectives-Cerebrospinal fluid (CSF) levels of neurofilament triplet protein (NFL), a non-specific marker of neuronal damage, are normal in Parkinson's disease (PD) but increased after brain trauma and in several neurological disorders. Using longitudinal CSF-NFL measurements as an indicator of neuronal damage, this study investigated the impact of deep brain stimulation (DBS) of the subthalamic nucleus (STN) on the brain, directly following the surgical intervention and in chronically treated patients with PD. Materials and methods-CSF-NFL levels were measured consecutively in eight patients with PD before and after STN-DBS treatment. Results-CSF-NFL levels were normal prior to STN-DBS and increased sharply during the first 2weeks post-operatively, but normalized after 12months or more. Conclusion-The STN-DBS procedure leads to an acute but limited neuronal damage, as expected. However, normal CSF-NFL levels at 12months post-operatively and beyond suggest the absence of any long-term neuronal damage caused by long-term STN-DBS stimulation.

Higher serum and cerebrospinal fluid (CSF) urate levels are associated with slower rates of clinical decline in PD and in multiple system atrophy (MSA). Aims To compare CSF and blood urate levels in healthy controls, patients with synucleinopathies and with tauopathies. Methods We investigated urate levels in serum and CSF from 18 healthy controls, 19 patients with synucleinopathies (six patients with PD and 13 with MSA), and 24 patients with tauopathies (18 with progressive supranuclear palsy and six with corticobasal degeneration). None of the patients were treated with dopaminergic medications. Results No significant differences were seen when comparing serum and CSF urate levels from controls across the parkinsonian diagnostic groups. However, in men, serum urate levels were significantly lower in the synucleinopathy group compared with the tauopathy group (P = 0.046), although with a broad overlap. Conclusion Our study suggests that urate levels might provide new insights into the potential pathophysiological mechanisms underlying Parkinsonism and thereby contribute to the future management of these disorders.

Cox regression analyses were used to assess all-cause mortality according to hospital volume and resection rate, adjusting for case-mix variables (sex, age, socioeconomic deprivation, comorbidity and type of cancer). HRs and 95% CIs, according to hospital volume, were evaluated for three predefined periods following surgery: <30, 30-365, and >365 days. Analysis of mortality in relation to resection rate was performed among all patients and among the 13 189 (21%) resected patients.RESULTS:Increasing hospital volume was associated with lower mortality (p(trend)=0.0001; HR 0.87, 95% CI 0.79 to 0.95 for hospitals resecting 80+ and compared with <20 patients a year). In relative terms, the association between increasing hospital volume and lower mortality was particularly strong in the first 30 days following surgery (p(trend)<0.0001; HR 0.52, (0.39 to 0.70)), but a clinically relevant association remained beyond 1 year (p(trend)=0.0011; HR 0.82, (0.72 to 0.95)). Increasing resection rates were associated with lower mortality among all patients (p(trend)<0.0001; HR 0.86, (0.84 to 0.89) for the highest, compared with the lowest resection quintile).CONCLUSIONS:With evidence of lower short-term and longer-term mortality for patients resected in high-volume hospitals, this study supports further centralisation of oesophageal and gastric cancer surgical services in England.

We report on the long-term outcome after HTx at our centre and investigate trends in outcome over time.During the period, between 1984 and 2014, a total of 610 HTx procedures were performed in 595 patients (median 48years; IQR 31-57years; range 24days-71years; mean 43years; 75% male) in our institution. Long-term outcome was investigated in the whole cohort, among children (n=76), bridged with mechanical circulatory support (MCS, n=131), re-transplanted (n=17), and concomitant kidney transplantation (n=12).Long-term survival was at 1, 5, 10, 15 and 20years: 86% (95CI 0.83-0.89); 77% (95CI 0.73-0.80); 63% (95CI 0.59-0.68); 48% (95CI 0.43-0.54) and 30% (95CI 0.25-0.36), respectively. The median survival for the whole cohort was 14.1years. Patients transplanted during the most recent time period (2010-2014) had a better survival compared to previous eras, with a 1- and 3-year survival of 94% (95CI 0.89-0.97) and 93% (95CI 0.88-0.96), respectively (p<0.001). However, when survival was analysed for long-term MCS (n=80) versus short term MCS (n=35), there was a significantly poorer survival for the short-term MCS group (p=0.001). Independent predictors of long-term mortality included recipient age (p=0.041); previous smoking (p=0.034); ischemic heart disease (p=0.002); and preoperative ventilator therapy (p=0.004).We have shown that continuous improvement in outcome after HTx still occurs. In the last time era, direct transplantation from short-term MCS was abandoned, which may have inflicted outcome during the last time era.

Toxicity and dose intensity in the Scandinavian Breast Group phase 3 adjuvant Trial SBG 2000-1 2011 Ingår i: Acta Oncologica. - : Informa Healthcare. - 0284-186X .- 1651-226X. ; 50:3, s. 329-337 Tidskriftsartikel (refereegranskat)abstract The SBG 2000-1 trial is a randomised study that investigates if dose-tailored adjuvant FEC therapy based on the individual's leukocyte nadir value can improve outcome. The study has included 1535 women with medium and high-risk breast cancer. Patients and methods. After a first standard dosed FEC course (5-fluorouracil 600 mg/m(2), epirubicin 60 mg/mg(2) and cyclophosphamide 600 mg/m(2)), patients who did not reach leukopenia grade III or IV were randomised to standard doses (group standard) or doses tailored to achieve grade III leukopenia (group tailored) at courses 2 7. Patients who achieved leukopenia grade III or more after the first course were not randomised but continued on standard doses (group registered). Results. Both planned and actually delivered number of courses (seven) were the same in all three arms. The relative dose intensity was increased by a factor of 1.31 (E 1.22, C 1.43) for patients in the tailored arm compared to the expected on standard dose. Ninety percent of the patients in the tailored arm achieved leukopenia grade III-IV compared with 29% among patients randomised to standard dosed therapy. Dose tailoring was associated with acceptable acute non-haematological toxicity with more total alopecia, nausea, vomiting and fatigue. Conclusion. Dose tailoring according to leukopenia was feasible. It led to an increased dose intensity and was associated with acceptable excess of acute non-haematological toxicity.

Unexplained thrombocytosis and secondary erythrocytosis were associated with the highest rate of recurrent event as well as the most inferior restricted mean survival time.Conclusion: Elevated blood values are common in patients with thromboembolic event and the high risk of recurrent event and inferior restricted mean survival time in patients with unexplained thrombocytosis and secondary erythrocytosis implicates the importance of finding and managing the underlying condition.

We set out to explore if these differences still exist. Patients diagnosed with colorectal cancer as their first invasive cancer at age 15-89 in the period 1994-2000 were identified using data from 11 cancer registries in the UK and from four Nordic countries. Five-year relative period survival using deaths in 1999-2000 following cancers diagnosed in 1994-2000 was analysed with excess mortality risk modelling. Follow-up time since diagnosis with age as an effect-modifier in the first half year was the most important factor with the highest excess risk of death immediately after diagnosis and with higher age and decreasing with length of follow-up. Variations between countries were bigger in the first half year following diagnosis than in the interval 0.5-5 years with about 30% higher risk in UK and Denmark. The differences between countries are still substantial and the order has not changed, even if the five year relative survival has improved since the EUROCARE studies. Patient management, diagnostics, and comorbidity likely explain the excess deaths in UK and Denmark during the first 6 months. The effect of stage and quality of management and treatment should be examined in population based studies with detailed patient information. Use of more detailed age-intervals than conventionally applied in survival studies proved to be important in statistical modelling and is recommended for future studies.
47.	Fredholm, Hanna, et al. (författare) Breast cancer in young women : poor survival despite intensive treatment 2009 Ingår i: PLoS one. - : Public Library of Science (PLoS). - 1932-6203. ; 4:11, s. e7695- Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Breast cancer is uncommon in young women and correlates with a less favourable prognosis; still it is the most frequent cancer in women under 40, accounting for 30-40% of all incident female cancer. The aim of this study was to study prognosis in young women, quantifying how much stage at diagnosis and management on the one hand, and tumour biology on the other; each contribute to the worse prognosis seen in this age group. METHODOLOGY/PRINCIPAL FINDINGS: In a registry based cohort of women aged 20-69 (n = 22 017) with a primary diagnosis of invasive breast cancer (1992-2005), women aged 20-34 (n = 471), 35-39 (n = 858) and 40-49 (n = 4789) were compared with women aged 50-69 years (n = 15 899). The cumulative 5-year relative survival ratio and the relative excess mortality (RER) were calculated. The cumulative 5-year relative survival ratio was lowest in women aged 20-34. The RER was 2.84 for women aged 20-34 and decreased with increasing age (RER 1.76 and 1.17 for women aged 35-39 and 40-49, respectively). The excess risk was, however, present only in disease stages I and II. For women aged 20-34 with stage I disease RER was 4.63, and 6.70 in the subgroup with tumour size 1-10 mm. The absolute difference in stage I between the youngest and the reference groups amounted to nearly 8%, with a 90% 5-year survival in women aged 20-34. In stages IIa and IIb, the relative excess risk was not as dramatic, but the absolute differences approached 15%. The youngest women with small tumours generally received more aggressive treatment than women in older age groups. CONCLUSIONS: After correction for stage, tumour characteristics and treatment, age remained an independent risk factor for breast cancer death in women <35 years of age. The excess risk for young women was only seen in early stages of disease and was most pronounced in women with small tumours. Young women affected by breast cancer have a high risk of dying compared to their middle-aged counterparts even if diagnosed early and receiving an intense treatment.

(författare) Breast cancer in young women and prognosis : How important are proliferation markers? 2017 Ingår i: European Journal of Cancer. - : Elsevier BV. - 0959-8049 .- 1879-0852. ; 84, s. 278-289 Tidskriftsartikel (refereegranskat)abstract Aim:Compared to middle-aged women, young women with breast cancer have a higher risk of systemic disease. We studied expression of proliferation markers in relation to age and subtype and their association with long-term prognosis.Methods:Distant disease-free survival (DDFS) was studied in 504 women aged <40 years and 383 women aged >= 40 years from a population-based cohort. Information on patient characteristics, treatment and follow-up was collected from medical records. Tissue microarrays were produced for analysis of oestrogen receptor, progesterone receptor (PR), Her2, Ki-67 and cyclins.Results: Young women with luminal tumours had significantly higher expression of Ki-67 and cyclins. Proliferation markers were prognostic only within this subtype. Ki-67 was a prognostic indicator only in young women with luminal PR+ tumours. The optimal cut-off for Ki-67 varied by age. High expression of cyclin E1 conferred a better DDFS in women aged <40 years with luminal PR- tumours (hazard ratio [HR] 0.47 [0.24-0.92]). Age < 40 years was an independent risk factor of DDFS exclusively in women with luminal B PR+ tumours (HR 2.35 [1.22-4.50]). Young women with luminal B PR- tumours expressing low cyclin E1 had a six-fold risk of distant disease compared with luminal A ( HR 6.21 [2.17-17.6]).Conclusions:The higher expression of proliferation markers in young women does not have a strong impact on prognosis. Ki-67 is only prognostic in the subgroup of young women with luminal PR tumours. The only cyclin adding prognostic value beyond subtype is cyclin E1. Age is an independent prognostic factor only in women with luminal B PR+ tumours.
50.	Fredholm, Hanna, et al. (författare) Long-term outcome in young women with breast cancer : a population-based study 2016 Ingår i: Breast Cancer Research and Treatment. - : Springer Science and Business Media LLC. - 0167-6806 .- 1573-7217. ; 160:1, s. 131-143 Tidskriftsartikel (refereegranskat)abstract Whether young age at diagnosis of breast cancer is an independent risk factor for death remains controversial, and the question whether young age should be considered in treatment decisions is still to be answered. From a population-based cohort of 22,017 women with breast cancer, all women < 35 years (n = 471) were compared to a random sample of 700 women aged 35-69 years from the same cohort. Information on patient and tumor characteristics, treatment, and follow-up was collected from the medical records. Tissue microarrays were produced for analysis of classical biomarkers. Breast cancer-specific survival (BCSS), distant disease-free survival (DDFS), and locoregional recurrence-free survival (LRFS) by age were compared using women 50-69 years as reference. At 10 years follow-up, women < 35 years and 35-39 years had a worse BCSS [age < 35 years 69 % (HR 2.75, 95 % CI 1.93-3.94), age 35-39 years 76 % (HR 2.33, 95 % CI 1.54-3.52), age 40-49 years 84 % (HR 1.53, 95 % CI 0.97-2.39), and age 50-69 years 89 % (reference)]. The worse BCSS was statistically significant in stages I-IIa and Luminal B tumors. At multivariate analysis age < 35 years and 35-39 years confined a risk in LRFS (HR 2.13, 95 % CI 1.21-3.76 and HR 1.97, 95 % CI 1.06-3.68) but not in DDFS and BCSS. In the subgroup of women < 40 years with luminal tumors stage I-IIa, low age remained an independent risk factor also in DDFS (HR 1.87, 95 % CI 1.03-3.44). Young women have a high risk of systemic disease even when diagnosed in an early stage. The excess risk of relapse is most pronounced in Luminal B tumors, where low age is an independent prognostic factor of DDFS and LRFS.
