- In order to give all children equal opportunities in school, methods to prevent early differences are needed. The overall aim of this study was to investigate the effectiveness of two structured teaching methods: Math in Action, characterised by physical activity and music, and common numerical activities. Children (28 girls, 25 boys) were assigned to 1 of the 2 conditions during a period of 3 weeks (2 times a week for a 30-minute session). The results show that children who learn mathematics in an environment characterised by physical activity and music develop their mathematical abilities significantly more than children who learn mathematics through common number activities. We have also shown that children with different motor skill abilities benefit from learning mathematics in an environment characterised by physical activity and music.

- Background: The aim of this study was to investigate the clinical value of liquid biopsy as a primary source for variant analysis in lung cancer. In addition, we sought to characterize liquid biopsy variants and to correlate mutational load to clinical data.Methods: Circulating cell-free DNA was extracted from plasma from patients with lung cancer (n = 60) and controls with benign lung disease (n = 16). Variant analysis was performed using the AVENIO ctDNA Surveillance kit and the results were correlated to clinical and variant analysis data from tumor tissue or cytology retrieved from clinical routine diagnostics.Results: There were significantly more variants detected in lung cancer cases compared to controls (p = 0.011), but no difference between the histological subgroups of lung cancer was found (p = 0.465). Furthermore, significantly more variants were detected in patients with stage IIIb-IV disease compared to patients with stage I-IIIa (median 7 vs 4, p = 0.017). Plasma cfDNA mutational load was significantly associated with overall survival (p = 0.010). The association persisted when adjusted for stage and ECOG performance status (HR: 3.64, 95% CI 1.37-9.67, p = 0.009). Agreement between tumor and plasma samples significantly differed with stage; patients with stage IIIb-IV disease showed agreement in 88.2% of the cases with clinically relevant variants, compared to zero cases in stage I-IIIa (p = 0.004). Furthermore, one variant in EGFR, two in KRAS, and one in BRAF were detected in plasma but not in tumor samples.Conclusion: This study concludes that in the vast majority of advanced NSCLC patients a reliable variant analysis can be performed using liquid biopsy from plasma. Furthermore, we found that the number of variants in plasma is associated with prognosis, possibly indicating a strategy for closer follow up on this crucial patient group.

- Accumulating evidence suggest that Propionibacterium acnes may play a role in prostate carcinogenesis, but data are so far limited and inconclusive. The aim of this population-based cohort study was therefore to test whether presence of acne vulgaris during late adolescence is associated with an increased risk of prostate cancer later in life. We identified a large cohort of young men born in Sweden between 1952 and 1956, who underwent mandatory assessment for military conscription around the age of 18 (n= 243,187). Test information along with health data including medical diagnoses at time of conscription was available through the Swedish Military Conscription Register and the National Patient Register. The cohort was followed through linkages to the Swedish Cancer Register to identify the occurrence of prostate cancer until December 31st 2009. We used Cox regression to calculate adjusted hazard ratios (HR) and 95% confidence intervals (95% CI) for the association between acne in adolescence and prostate cancer risk. A total of 1,633 men were diagnosed with prostate cancer during a median follow-up of 36.7 years. A diagnosis of acne was associated with a statistically significant increased risk for prostate cancer (adjusted HR: 1.43 95%; CI: 1.06-1.92), particularly for advanced stage disease (HR: 2.37 95%; CI 1.19-4.73). A diagnosis of acne classified as severe conferred a 6-fold increased risk of prostate cancer (HR: 5.70 95% CI 1.42-22.85). Data from this large prospective population-based cohort add new evidence supporting a role of P acnes infection in prostate cancer.

- BACKGROUND: Appendicitis before age 20 years has been observed to influence the risk of several inflammatory conditions, possibly through underlying immunological mechanisms. Inflammation has further been suggested to be involved in prostate cancer development. We therefore hypothesized that immunological characteristics signaled by appendicitis before late adolescence might influence the risk of later prostate cancer, and aimed to evaluate this association in a population-based study.METHODS: We identified a large cohort of Swedish men who underwent assessment for military conscription around the age of 18 years (n= 242,573). Medical diagnoses at time of conscription were available through the Swedish Military Conscription Register. The Swedish Cancer Register was used to identify diagnoses of prostate cancer. Multivariable adjusted Cox regression analyses were used to estimate hazard ratios (HR) and 95% confidence intervals (95% CI) for the association between appendicitis and prostate cancer.RESULTS: During a median of 36.7 years of follow-up, 1,684 diagnoses of prostate cancer occurred. We found a statistically significant association between appendicitis and overall prostate cancer (adjusted HR: 1.70; 95% CI: 1.08-2.67). The risk was notably increased for advanced (HR: 4.42; 95% CI: 1.74-11.22) and lethal (HR: 8.95; 95% CI: 2.98-26.91) prostate cancer.CONCLUSION: These results suggest that a diagnosis of appendicitis before adulthood potentially signals underlying immune characteristics and a pattern of inflammatory response relevant to prostate cancer risk.IMPACT: The study lends support to the proposed role of inflammation in prostate carcinogenesis, and adds another area of investigation potentially relevant to prostate cancer development.

Inflammation and prostate carcinogenesis : influence of immune characteristics and early-adulthood exposure to inflammatory conditions on prostate cancer risk
- 2019

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Chronic inflammation has been implicated in the development of several types of cancer, and evidence from observational and animal studies suggests that it may play a role also in prostate carcinogenesis. Recent observations have brought Cutibacterium acnes (C. acnes) forward as a possible causative agent in pro-oncogenic prostatic inflammation. However, evidence also suggest that underlying immune characteristics contribute to prostate cancer risk. The overall aim of this thesis was to explore potential mechanisms underlying the proposed link between inflammation and prostate cancer, by evaluating associations between inflammatory conditions during early adulthood, circulating inflammation markers, and prostate cancer. Due to the suggested role of C. acnes in both diseases, we aimed to investigate whether acne vulgaris is a determinant of prostate cancer. Using prospectively collected data from Swedish national registers, we observed that presence of acne during early adulthood conferred an increased risk of prostate cancer later in life. Similarly, we found that appendicitis before late adolescence – a proposed marker of individual immune characteristics – to be positively associated with subsequent prostate cancer. We further evaluated whether prostatic C. acnes infection is linked with elevated systemic levels of IL6 and CXCL8, two inflammation markers previously associated with prostate cancer. No association was observed, however, potentially explained by the subclinical low-grade infection typically caused by C. acnes. Finally, we evaluated 52 circulating inflammation markers as determinants for prostate cancer in a population-based case-control study. In this hypothesis-generating study, we identified CX3CL1, CCL21, PDGF-BB, CCL11 and IL10 as candidate markers for evaluation in prospective studies. If confirmed, these markers may hint at targetable molecular pathways involved in prostate carcinogenesis.

Tidskriftsartikel (refereegranskat)abstract
- Background: Chronic prostatic inflammation, caused by Cutibacterium acnes (C. acnes), has been proposed to influence the risk of prostate cancer development. In vitro studies have demonstrated the capacity of C. acnes to induce secretion of Interleukin 6 (IL6) and C-X-C motif chemokine ligand 8 (CXCL8) by prostate epithelial cells. Both these inflammatory mediators have been implicated in prostate cancer pathophysiology. In this cohort study, we aimed to investigate the influence of prostatic C. acnes on serum levels of IL6 and CXCL8.Methods: We recruited 99 prostate cancer patients who underwent radical prostatectomy at orebro University Hospital. The cultivation of pre-operatively obtained prostate biopsies identified C. acnes in 60 of the 99 patients. Levels of IL6 and CXCL8 in pre-operative serum samples were analyzed using ELISA, and concentrations were compared between prostate cancer patients with and without prostatic C. acnes infection using standard statistical methods.Results: No statistical differences were observed in serum levels of IL6 and CXCL8 between subjects with and without prostatic C. acnes infection.Conclusions: Our results indicate that prostatic C. acnes infection may give rise to low-grade inflammation with little effect on systemic levels of IL6 and CXCL8.
