Abstract
The worldwide problem of increasing dairy cow mortality is widespread in modern production systems, it causes economic losses, and indicates problems with herd health and welfare. Most studies on causes of dairy cow mortality are limited as they are based on secondary register data, or questionnaires for producers or veterinarians, and neither necropsies nor histopathologic analyses are usually performed. For this reason, no definite causes for dairy cow deaths have been determined making it difficult or impossible to implement effective preventive measures. The objectives of this study were to (1) determine the causes of on-farm mortality of Finnish dairy cows, (2) determine the usefulness of routine histopathologic analysis in bovine necropsies, and (3) assess how reliable producers' perception about the cause of death is. Underlying diagnoses of on-farm deaths were determined through necropsy of 319 dairy cows at an incineration plant. The necropsy data were combined with background information obtained from online questionnaires covering cow and herd records. Mastitis was the most common underlying diagnosis of death (26.6%), followed by digestive disorders (15.4%), other known disorders (13.8%), calving-associated disorders (12.2%), and locomotion disorders (11.9%). The underlying diagnoses of death varied during different stages of lactation and with parity. A large proportion of the study cows (46.7%) died during the first 30 d after calving, and of those, 63.6% died during the first 5 d. A routine histopathologic analysis was performed in every necropsy, and it changed the preliminary gross diagnosis in 18.2% of the cases. Producers' perception about the cause of death agreed with the necropsy-based underlying diagnosis of death in 42.8% of the cases. It was most consistent for mastitis, calving disorders, locomotion diseases, and accidents. In cases where producers had no insights about the cause of death, necropsy revealed the final underlying diagnosis in 88.2% of cases, demonstrating the usefulness of necropsy. Based on our findings, necropsies provide useful and reliable information to develop control programs for cow mortality. Including routine histopathologic analysis in necropsies, more accurate information may be obtained. Furthermore, targeting preventive measures on transitional cows may be most effective, as the number of deaths was highest at this time.

Abstract
BackgroundSeveral autoimmune inflammatory diseases, including rheumatoid arthritis (RA), are associated with increased risk of malignant lymphomas. There is also a longstanding concern of lymphoma development with tumour necrosis factor inhibitor (TNFi) treatment, but most studies in RA to date do not indicate an additionally increased risk. Corresponding studies in psoriatic arthritis (PsA), both with respect to the underlying risks, and risks in relation to treatment with TNFi, are limited. Data on myeloid malignancies in PsA are scarce.ObjectivesTo estimate the risk of haematological malignancy overall and by lymphoid and myeloid types in TNFi treated versus (vs.) biologics-naïve patients with PsA across the five Nordic countries. Additionally, we investigated the underlying risk of haematological malignancies in PsA as compared to the general population.MethodsWe identified patients with PsA starting a first ever TNFi from the clinical rheumatology registers (CRR) in Sweden (SE), Denmark (DK), Norway (NO), Finland (FI), and Iceland (ICE) from 2006 through 2019 (n=10 621). We identified biologics-naïve patients with PsA from a) the CRR (n=18 705, all countries) and b) the national patient registers (NPR, n=27 286, SE and DK only). To estimate the underlying risk of haematological malignancy in PsA, we randomly sampled general population comparators in SE and DK matched on year of birth, sex, and calendar year at start of follow-up, to the patients with PsA.Through linkage to the mandatory national cancer registers in all five countries, we collected information on haematological malignancy overall, and categorised into lymphoid or myeloid types. By applying a modified Poisson regression, we estimated pooled incidence rate ratio (IRR) with 95% confidence intervals (CI) for TNFi treated vs. biologics-naïve PsA and for PsA vs. the general population, adjusted for age (18-55, 56-65, 66-70, >70 years), sex, calendar period (2006-2010, 2011-2019) and country, and using robust standard errors.ResultsWe observed 40 events of haematological malignancies (during 59 827 person-years) among TNFi treated PsA, resulting in a crude incidence rate (IR) of 67 per 100 000 person-years. The corresponding IR was 91 (63 events) for biologics-naïve PsA from the CRR, and 118 (172 events) for biologics-naïve PsA from NPR. This resulted in a pooled IRR of 0.97 (0.69 to 1.37) for TNFi-treated vs. biologics-naïve PsA patients from the CRR, and 0.84 (0.64 to 1.10) vs. biologics-naïve PsA patients from the NPR. The pooled IRR of haematological malignancies in PsA overall vs. the general population was 1.35 (1.17 to 1.55). Throughout, the estimates were largely similar for lymphoid and myeloid malignancies (Figure 1). The crude IR of haematological malignancies were substantially akin across different TNFi agents.Figure 1.Pooled incidence rate ratios (IRRs) (95% CI) of haematological malignancy overall and by lymphoid and myeloid types, in first ever TNFi treated versus biologics-naïve patients with PsA, and versus general population comparators. Legend: Lymphoid malignancies include international classification of diseases (ICD) 10 codes C81-86, C88, C90-91. Myeloid malignancies include ICD10 codes C92-95, D45-D46, D47.1, D47.3-5. Incidence rate ratios adjusted for age (18-55, 56-65, 66-70, >70 years), sex, calendar period (2006-2010, 2011-2019) and country, and using robust standard errors.ConclusionIn this large five-country cohort study, we did not observe any increased risk of haematological malignancies overall, nor for lymphoid and myeloid types, in patients with PsA treated with TNFi. By contrast, there were signals of a moderately increased underlying risk of haematological malignancies, both of lymphoid and myeloid types, in patients with PsA overall as compared to the general population. The findings are of importance from a patient information perspective.AcknowledgementsWe would like to acknowledge the NordForsk and FOREUM, and especially the patient representatives of the NordForsk collaboration for their valuable contribution to this study.Disclosure of InterestsRené Cordtz: None declared, Johan Askling Consultant of: Abbvie, Astra-Zeneca, BMS, Eli Lilly, MSD, Pfizer, Roche, Samsung Bioepis, Sanofi, and UCB, Grant/research support from: Abbvie, Astra-Zeneca, BMS, Eli Lilly, MSD, Pfizer, Roche, Samsung Bioepis, Sanofi, and UCB, Bénédicte Delcoigne: None declared, Karin Ekström Smedby: None declared, Eva Baecklund: None declared, Christine Ballegaard: None declared, Pia Isomäki Speakers bureau: AbbVie, Eli Lilly and Pfizer, Consultant of: AbbVie, Eli Lilly, Pfizer, Roche and ViforPharma, Grant/research support from: Pfizer, Kalle Aaltonen: None declared, Björn Gudbjornsson Speakers bureau: Novartis, not related to this work, Consultant of: Novartis, not related to this work, Thorvardur Love Speakers bureau: Celgene, Sella Aa.

Abstract
Background:In clinical practice, some patients with axial spondyloarthritis (axSpA) fail several consecutive biological treatments (bDMARDs). How this group of ”refractory” patients should best be defined, how common they are, and what their characteristics are, is poorly understood.Objectives:To explore the point prevalence of bDMARD refractory disease in axSpA over time, according to different definitions, and to describe the characteristics of refractory vs. not-refractory patients upon start of their first bDMARD.Methods:Observational prospective cohort study. Patients with axSpA (ankylosing spondylitis/non-radiographic axial SpA) starting a first bDMARD 2009-2018 were identified in biologic registries in Denmark, Sweden, Finland, Norway and Iceland. Clinical characteristics and treatments were retrieved, and data were pooled for analysis.Refractory disease was defined based on the number of different bDMARD treatments started in individual patients: mild (≥3 bDMARDs), moderate (≥4), and strict (5 or more). Restart of same bDMARD with another bDMARD in between counted as separate courses whereas switch from originator to corresponding biosimilar was ignored.Proportions of patients fulfilling each definition of refractory disease at 2 and 5 years after the start of 1st bDMARD were calculated.Point-prevalence per calendar-year was calculated as the number of patients with refractory disease at the end of each year, divided by the total number of patients ever having starting a first bDMARD before that time-point, and who were still alive and resident in the country.Results:The point prevalence of refractory axSpA increased with calendar-time (Figure). Among 12,037 included axSpA patients (64% male), the point-prevalence of bDMARD refractory disease in 2018 was 16%/7%/3% according to mild/moderate/strict definitions (Table).Table 1.Biologic refractory axSpA according to three definitionsA.Baseline characteristics upon start 1st bDMARDRefractory definitionOverall cohortMILDMODERATESTRICTN120371969832351Age, years42 (13)41 (12)41 (12)41 (12)Male, %64%57%54%56%Disease duration, years7 (10)6 (9)6 (8)5 (8)BASDAI, 0-10053 (28)60 (29)63 (27)66 (35)ASDAS3.3 (1.1)3.5 (1.2)3.6 (1.0)3.7 (1.1)CRP, mg/L16 (23)18 (26)21 (28)23 (32)Patient global, VAS, 0-10059 (25)65 (22)66 (22)67 (23)Patient Pain, VAS, 0-10057 (24)62 (22)63 (22)63 (22)Fatigue, VAS, 0-10059 (27)66 (26)66 (26)68 (25)B.Proportions of patients having refractory disease 2 and 5 years after start of their first bDMARD2 years, %5%1%0%5 years, %13%4%1%Numbers are means (SD) unless otherwise statedUpon start of their 1st bDMARD, patients later fulfilling the definitions for refractory axSpA were more frequently women, had shorter disease duration, higher C-reactive protein and higher patient reported outcomes.Overall, 5%/1%/0% had mild/moderate/strict refractory disease 2 years after start of first bDMARD, after 5 years it was 13%/4%/1% (Table).Conclusion:In this large Nordic observational cohort of axSpA patients treated in routine care, we could demonstrate that a substantial proportion of all patients had used multiple bDMARDs. In 2018, one in six patients had received ≥3 bDMARDs, indicating a bDMARD refractory disease. Multiple switching was more frequent during later years, probably due to more bDMARDs becoming available. The characteristics of refractory axSpA, including sex and disease activity, will have to be further explored, as will the impact of refractory disease on long-term outcomes.Acknowledgements:the DANBIO, SRQ, ICEBIO, ROB-FIN and NOR-DMARD registries.Partly sponsored by Nordforsk and Foreum.Disclosure of Interests:Daniela Di Giuseppe: None declared, Ulf Lindström: None declared, Kalle Aaltonen: None declared, Heikki Relas Speakers bureau: Abbvie, Celgene, MSD, Roche, Sella Aarrestad Provan: None declared, Björn Gudbjornsson Speakers bureau: Amgen and Novartis, Merete L.

Abstract
Background:Interstitial lung disease (ILD) is an established extra-articular manifestation of rheumatoid arthritis (RA). Few studies have investigated the prevalence of ILD in patients with psoriatic arthritis (PsA). Methotrexate (MTX) is frequently used in the treatment of both RA and PsA and has been suggested to be a risk factor for the development of ILD. It is of interest to understand the interaction between disease and treatment in the development of ILD.Objectives:To compare the incidence of ILD between patient with PsA and RA treated with biologic disease modifying antirheumatic drugs (bDMARDS), with or without MTX as a co-medication.Methods:Cohorts of patients with RA and PsA starting bDMARD were identified in Nordic registers (Danish nationwide clinical register for patients with RA (DANBIO), Register on antirheumatic and biological therapy in Finland (ROB-FIN), Icelandic nationwide database of biologic therapy (ICEBIO), Norwegian Antirheumatic Drug Register (NOR-DMARD), and the Swedish Rheumatology Quality Register (SRQ)). Linkages to the National Patient Registers and to the Cause of Death Registers were performed in each country to identify cases of ILD. Each individual patient could contribute several treatment courses. ILD was identified as hospital or death certificate ICD10 codes of ILD (J84.1, J84.8, J84.9, J70.2, J70.3, J70.4, J99.0, J99.1, J99.8) given during the follow-up period which was defined as the treatment course duration, plus a 30-day wash-out period added to the end of treatment course period. MTX co-medication was specified as use of MTX at the start of bDMARD. Incidence rates (IR) for any ILD were calculated per 1000 person years at risk (PYR) for each country. The five cohorts were pooled and incidence rate ratios (IRR) for PsA vs. RA were calculated. Hazard ratios (HR) for any ILD in PsA vs. RA were estimated in Cox regression models adjusted for age, gender and repeated observations, and stratified for the use of MTX co-medication.Results:Overall 47 987 individual patients representing 89 239 bDMARD treatment courses and contributing 201 279 PYR were included in the study (Table 1). Methotrexate was reported as comedication in 29 916 (33.5 %) of the treatment courses (PsA vs. RA, 30.4 % vs 34.5 %). 970 cases of ILD were identified during the follow-up period. The risk of ILD was consistently lower in patients with PsA compared to patients with RA in all countries. In models stratified for co-medication the HR for ILD in PsA vs. RA was 0.34 (0.21-0.57) in patients treated with MTX and 0.26 (0.18-0.36) in patients not treated with MTX.Table 1.Interstitial lung disease in PsA vs. RA in five Nordic biologic registersDENMARKFINLANDICELANDNORWAYSWEDENRAPsARAPsARAPsARAPsARAPsANumber of individuals78293386494610916754701590999205966393Number of treatment courses17 07266408634184512808592379142738 27910 824Age baseline (SD)57.3 (13.1)49.0 (12.6)53.8 (13.4)48.8 (11.4)53.9 (14.2)50.1 (13.3)53.8 (13.7)48.7 (12.0)57.1 (13.7)50.6 (12.8)Female n (%)12 963 (76)3929 (59)6571 (76)933 (51)969 (76)551 (65)1815 (77)818 (57)29 635 (77)6162 (57)Number of PYR4023513986217984910451727994556265312033427412ILD-events within PYR2182213287232668028IR pr 1000 PYR5.41.66.11.61.50.77.02.35.71.0IRR PsA vs RA crude0.29 (0.18-0.45)0.27 (0.11-0.55)0.46 (0.05-2.42)0.32(0.11-0.78)0.18 (0.12-0.26)HR PsA vs RA0.31 (0.17-0.56)0.46 (0.22-0.96)0.62 (0.12-3.14)0.19 (0.06-0.54)0.25 (0.17-0.37)PYR: Patient years at risk, IR: Incidence rates, IRR: Incidence rate ratios, HR: Hazard RatiosConclusion:In these preliminary analyses, the incidence of ILD is lower in bDMARD treated PsA vs. RA patients, irrespective of co-medication with MTX.

Abstract
Background:Tumor necrosis factor inhibitors (TNFi) have been available for more than a decade for treatment of spondyloarthrtitis (SpA). Secukinumab (SEC) represents a new mode of action, but few studies have compared outcomes in patients(pts) treated with SEC vs TNFi – and the optimal treatment strategy in routine care remains to be established. Comparative studies between SEC and adalimumab (ADA) are ongoing.Objectives:To describe baseline characteristics and compare 1-yr treatment retention of SEC vs TNFi (ADA/certolizumab pegol(CLZ)/etanercept(ETN)/golimumab(GOL)/infliximab(IFX)) in SpA-pts from 5 Nordic countries.Methods:Observational, prospective cohort study. Pts with SpA (ankylosing spondylitis/non-radiographic axial SpA/undifferentiated SpA) starting SEC or any TNFi during 2015-2018 were identified in clinical rheumatology registries of the Nordic countries. Baseline characteristics were retrieved. Country-specific data were pooled. 1-yr treatment retention of SEC vs TNFi was assessed through crude survival probability curves, retention rates and adjusted Cox regression analyses (ADA reference). Analyses were stratified by line of bDMARD and TNFi type.Results:In total, 10692 treatment courses (834 SEC, 9858 TNFi) in 7952 patients were included. SEC was rarely used as 1stbDMARD (Table 1), whereas it was the drug most frequently used as 3rd+ line (Table 2). Baseline characteristics were numerically similar for SEC vs TNFi (Table 1).Table 1.Patient characteristics at treatment start1stline2ndline3rd+ lineSECTNFiSECTNFiSECTNFiN70518615626056082067Male, %535544534546Age, yrs45 (14)41 (14)45 (12)44 (13)47 (12)46 (13)BASDAI, mm45 (28)53 (22)52 (22)52 (24)63 (22)58 (24)Concomitant csDMARD, %182723232726Means (SD) unless otherwise statedTable 2.Table 2. 1-yr treatment retention (Kaplan Meier, Cox Regression)DrugRetentions rates, 1 yr % (95% CI)Adjusted* HR (95% CI) for discontinuation1stlineADA76 (73-79)1CLZ68 (63-72)1.4 (1.1-1.8)ETN74 (71-76)1.1 (0.9-1.3)GOL80 (77-84)0.8 (0.6-1.0)IFX65 (62-67)1.5 (1.3-1.8)SEC76 (62-85)0.9 (0.5-1.6)2ndlineADA72 (68-75)1CLZ58 (51-64)1.5 (1.2-1.9)ETN65 (61-68)1.2 (1.0-1.5)GOL73 (67-77)0.9 (0.7-1.2)IFX67 (63-71)1.2 (0.9-1.5)SEC67 (58-74)1.1 (0.8-1.5)3rd+ lineADA73 (68-77)1CLZ52 (46-57)2.0 (1.6-2.6)ETN65 (61-70)1.3 (1.0-1.6)GOL65 (60-70)1.3 (1.0-1.7)IFX61 (56-66)1.5 (1.2-1.9)SEC61 (57-65)1.4 (1.1-1.8)* by sex, baseline age, BASDAI, concomitant csDMARD (y/n/missing).

However, SEC retention was poorer than ADA when used as 3rd+ therapy, but comparable to retention of other TNFi.In adjusted Cox regression analyses, confidence intervals were wide and included 1 for SEC vs ADA (1st, 2ndline), whereas there was slightly poorer retention of SEC versus ADA when used as 3rd+ bDMARD (Table 2).Conclusion:These observational data in >10.000 biological treatment courses in SpA, showed that SEC was mainly used in bDMARD experienced pts. Baseline characteristics were similar in pts treated with SEC vs TNFi.

Abstract
Abstract
Introduction:
Although prognosis and treatment of metastatic breast cancer (MBC) have improved over the last years, there is still an unmet clinical need for more precise prognostic and treatment monitoring tools. Liquid-based markers are preferred since they reflect real-time tumor progression and are not dependent on repeated invasive tissue biopsies. Thymidine kinase 1 (TK1) is an enzyme involved in nucleotide metabolism and has a fundamental role in the DNA synthesis. It can be used as a marker of cell proliferation rate and the TK1 activity has demonstrated correlations to prognosis and usefulness for treatment monitoring in different malignancies. The aim of this study was to determine serum TK1 activity (sTK1) levels measured with the DiviTum assay (Biovica, Sweden), in women with MBC scheduled for 1st line systemic therapy and to evaluate its potential for prediction of outcome and treatment monitoring.
Methods:
142 women with MBC scheduled for 1st line systemic treatment and included in a prospective monitoring trial (CTC-MBC, NCT01322893) were evaluated for sTK1 at baseline (BL) and during treatment at 1, 3 and 6 months. 132 patients had at least one follow-up sample. sTK1 activity levels were measured and correlations to important clinicopathological variables and prognosis (PFS and OS) at BL and during treatment were evaluated.
Results:
The median sTK1 level at BL was 391 u/L (range 10-35520 u/L). When comparing patients with high (above median) versus low (below median) sTK1 levels at BL, high sTK1 levels were found to be associated to worse performance status (p=0.001) and high number of metastatic sites (p=0.03). There was also a statistically significant association between high sTK1 levels and high Ki67 expression in biopsies from metastatic lesions (p=0.038). In univariable analyses high sTK1 levels correlated to worse PFS and OS (HRPFS-BL 2.32, p<0.001; HROS-BL 2.54, p<0.001) at BL. In multivariable analysis adjusted for clinically used prognostic factors, sTK1 was an independent prognostic factor for PFS and OS (HRPFS-BL 2.4, p<0.001; HROS-BL 2.0, p=0.01). During treatment, sTK1 was significantly associated with OS from each of the four time points and onwards (BL, 1, 3, 6 months) (HROS-1m 1.93, p=0.01; HROS-3m 2.35, p=0.02; HROS-6m 2.78, p=0.002) in univariable analysis. High sTK1 levels were also associated with impaired PFS (HRPFS-1m 1.48, p=0.06; HRPFS-3m 1.52, p=0.07; HRPFS-6m 2.03, p=0.009) and these associations were significant at BL and 6 months.
Discussion:
sTK1 activity level is an independent prognostic factor for PFS and OS in patients with MBC scheduled for 1st line systemic therapy. During treatment, sTK1 is prognostic for OS evaluated from all time-points up to 6 months. The sTK1 effects observed for PFS are slightly weaker, but still propose potential usefulness for treatment monitoring. Further, sTK1 levels correlate to Ki67 expression in metastatic lesions suggesting that it can be useful as a liquid-based real-time proliferation marker. In conclusion, these results are clinically relevant for prognostication and treatment monitoring in patients with MBC. Future studies of sTK1 are justified to further elucidate in what settings this marker is most useful.

Abstract
Abstract
Introduction: Preoperative chemotherapy in early breast cancer increases the rate of breast preservation and provides prognostic information. In the case of residual disease, a change in subtypes may be observed. Sensitive and reproducible biomarkers predicting treatment response early during the treatment course are needed in order to better exploit the potential benefit of an individualized preoperative treatment.
Material and Methods: In an ongoing prospective study within the population-based SCAN-B project (NCT02306096), patients undergoing preoperative chemotherapy for early or locally recurrent breast cancer have been treated with iv Epirubicin and Cyclophosphamide q3w x 3 in sequence with either Docetaxel q3w x 3 or Paclitaxel q1w x 9 with a preoperative intent. HER2-positive cases also received HER2-directed treatment. At baseline, patients were staged using sentinel node biopsy for clinically node-negative patients and CT scan for cytologically confirmed node-positive cases. A clinical core needle biopsy as well as tissue from the surgical specimen was collected for determination of conventional biomarkers including ER, PgR, HER2 and Ki67. Tumor biopsies for biomolecule-extraction and RNA-sequencing were taken using ultrasound guidance and collected fresh in RNAlater at baseline, after 2 treatment cycles, as well as at surgery. Blood plasma samples were collected at baseline, after one-, three-, and six- 3w treatment cycles, and post-surgery. Using RNA-sequencing data, somatic mutations were identified in the tumor biopsies and personalized analyses for circulating tumor DNA (ctDNA) were performed. A pathological complete remission (pCR) was defined as the complete disappearance of invasive breast cancer in the breast and axilla at time of definitive surgery. Subtyping was performed using modified St Gallen criteria (2013).
Results: Thus far, 45 patients aged 24-74 years have been included, of which 34 (76 %) were clinical stage 2 and 11 (24%) were stage 3. The subtype distribution at baseline was five Luminal A-like (11 %), 21 Luminal B-like (HER2 negative) (47 %), 8 HER2-positive (18 %) and 11 Triple-negative (ductal) (24 %). The rates of pCR in 38 operated cases to date were 0/3 Luminal A-like, 3/19 Luminal B-like (HER2 negative), 2/8 HER2-positive, and 4/7 Triple-negative (overall 24 % pCR rate). One patient did not undergo surgery due to clinically progressive disease. In 25 cases with evaluable residual disease at surgery, there was a shift in the subtype in 13 (52 %), the majority of which represented a transition from Luminal B to Luminal A. No Triple-negative cases underwent a change in subtype during treatment. Results of the ctDNA analyses will be presented at the meeting.
Discussion: We have established an infrastructure allowing for an extensive evaluation of preoperative chemotherapy in early breast cancer. The goal is to develop methods to refine response-guided treatment in early breast cancer using molecular responses in the tumor as well as in the blood circulation. The patients continue to be prospectively monitored with iterative ctDNA analyses during follow-up.

Abstract
IntroductionSubstantial evidence supports association between childhood maltreatment and suicidal behaviour, however, a limited number of studies have examined psychological mechanisms mediating the relationship among patients with mood disorders.ObjectiveTo investigate directly the potential intermediating mechanisms between childhood maltreatment and suicidal behaviour among patients with mood disorders.AimsWe examine by formal mediation analyses, if:– the effect of childhood maltreatment on suicidal behaviour is mediated through borderline personality disorder traits;– the mediation effect differs between lifetime suicidal ideation and lifetime suicide attempts.MethodsDepressive disorder and bipolar disorder (ICD-10-DCR) patients (n = 287) from the Helsinki university psychiatric consortium (HUPC) Study were surveyed on self-reported childhood experiences, current depressive symptoms, borderline personality disorder traits and lifetime suicidal behaviour. Psychiatric records served to complement the information on suicide attempts.ResultsThe influence of childhood maltreatment on lifetime suicidal ideation and lifetime suicide attempts showed comparable total effects. In formal mediation analyses, borderline personality disorder traits mediated all of the total effect of childhood maltreatment on lifetime suicide attempts, but only 21% of the total effect on lifetime suicide ideation. The mediation effect was stronger for lifetime suicide attempts compared to ideation (P = 0.002) and independent of current depressive symptoms.ConclusionsThe mechanisms of the effect of childhood maltreatment on suicidal ideation and attempts may diverge among psychiatric patients with mood disorders. Borderline personality disorder traits may contribute to these mechanisms, although the influence appears considerably stronger for suicide attempts than for suicide ideation.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND Self-reported psychosis-like experiences (PEs) may be common in patients with mood disorders, but their clinical correlates are not well known. We investigated their prevalence and relationships with self-reported symptoms of depression, mania, anxiety, borderline (BPD) and schizotypal (SPD) personality disorders among psychiatric patients with mood disorders. METHODS The Community Assessment of Psychic Experiences (CAPE-42), Mood Disorder Questionnaire (MDQ), McLean Screening Instrument (MSI), The Beck Depressive Inventory (BDI), Overall Anxiety Severity and Impairment Scale (OASIS) and Schizotypal Personality Questionnaire-Brief form (SPQ-B) were filled in by patients with mood disorders (n=282) from specialized care. Correlation coefficients between total scores and individual items of CAPE-42 and BDI, SPQ-B, MSI and MDQ were estimated. Hierarchical multivariate regression analysis was conducted to examine factors influencing the frequency of self-reported PE. RESULTS PEs are common in patients with mood disorders. The "frequency of positive symptoms" score of CAPE-42 correlated strongly with total score of SPQ-B (rho=0.63; P<0.001) and moderately with total scores of BDI, MDQ, OASIS and MSI (rho varied from 0.37 to 0.56; P<0.001). Individual items of CAPE-42 correlated moderately with specific items of BDI, MDQ, SPQ-B and MSI (rφ varied from 0.2 to 0.5; P<0.001). Symptoms of anxiety, mania or hypomania and BPD were significant predictors of the "frequency of positive symptoms" score of CAPE-42. CONCLUSIONS Several, state- and trait-related factors may underlie self-reported PEs among mood disorder patients. These include cognitive-perceptual distortions of SPD; distrustfulness, identity disturbance, dissociative and affective symptoms of BPD; and cognitive biases related to depressive or manic symptoms.

Abstract
BACKGROUND Comorbid anxiety symptoms and disorders are present in many psychiatric disorders, but methodological variations render comparisons of their frequency and intensity difficult. Furthermore, whether risk factors for comorbid anxiety symptoms are similar in patients with mood disorders and schizophrenia spectrum disorders remains unclear. METHODS The Overall Anxiety Severity and Impairment Scale (OASIS) was used to measure anxiety symptoms in psychiatric care patients with schizophrenia or schizoaffective disorder (SSA, n=113), bipolar disorder (BD, n=99), or depressive disorder (DD, n=188) in the Helsinki University Psychiatric Consortium Study. Bivariate correlations and multivariate linear regression models were used to examine associations of depressive symptoms, neuroticism, early psychological trauma and distress, self-efficacy, symptoms of borderline personality disorder, and attachment style with anxiety symptoms in the three diagnostic groups. RESULTS Frequent or constant anxiety was reported by 40.2% of SSA, 51.5% of BD, and 55.6% of DD patients; it was described as severe or extreme by 43.8%, 41.4%, and 41.2% of these patients, respectively. SSA patients were significantly less anxious (P=0.010) and less often avoided anxiety-provoking situations (P=0.009) than the other patients. In regression analyses, OASIS was associated with high neuroticism, symptoms of depression and borderline personality disorder and low self-efficacy in all patients, and with early trauma in patients with mood disorders. CONCLUSIONS Comorbid anxiety symptoms are ubiquitous among psychiatric patients with mood or schizophrenia spectrum disorders, and in almost half of them, reportedly severe. Anxiety symptoms appear to be strongly related to both concurrent depressive symptoms and personality characteristics, regardless of principal diagnosis.

Abstract
BACKGROUND Distinguishing between symptoms of schizotypal (SPD) and borderline personality disorders (BPD) is often difficult due to their partial overlap and frequent co-occurrence. We investigated correlations in self-reported symptoms of SPD and BPD in questionnaires at the levels of both total scores and individual items, examining overlapping dimensions. METHODS Two questionnaires, the McLean Screening Instrument (MSI) for BPD and the Schizotypal Personality Questionnaire Brief (SPQ-B) for SPD, were filled in by patients with mood disorders (n=282) from specialized psychiatric care in a study of the Helsinki University Psychiatric Consortium. Correlation coefficients between total scores and individual items of the MSI and SPQ-B were estimated. Multivariate regression analysis (MRA) was conducted to examine the relationships between SPQ-B and MSI. RESULTS The Spearman's correlation between total scores of the MSI and SPQ-B was strong (rho=0.616, P<0.005). Items of MSI reflecting disrupted relatedness and affective dysregulation correlated moderately (rφ varied between 0.2 and 0.4, P<0.005) with items of SPQ. Items of MSI reflecting behavioural dysregulation correlated only weakly with items of SPQ. In MRA, depressive symptoms, sex and MSI were significant predictors of SPQ-B score, whereas symptoms of anxiety, age and SPQ-B were significant predictors of MSI score. CONCLUSIONS Items reflecting cognitive-perceptual distortions and affective symptoms of BPD appear to overlap with disorganized and cognitive-perceptual symptoms of SPD. Symptoms of depression may aggravate self-reported features of SPQ-B, and symptoms of anxiety features of MSI. Symptoms of behavioural dysregulation of BPD and interpersonal deficits of SPQ appear to be non-overlapping.

Abstract
Abstract
Background: Available targeted therapies have improved the prognosis for many women diagnosed with breast cancer. However, more than 15% of cases do not benefit from these targeted agents. Amongst these are tumours with Breast cancer 1 (BRCA1) dysfunction, triple-negative and basal-like breast cancers, which remain a treatment challenge and are associated with a poor outcome. New approaches to specifically target these groups of breast tumors are needed. The DNA damage repair defects associated with lack of BRCA1 confers sensitivity to poly-(ADP-ribose) polymerase 1 (PARP-1) inhibitors. Furthermore, most BRCA1 mutated tumours do not express the phosphatase and tensin homolog (PTEN) implying activation of the phosphatidylinositol-3 kinase (PI3K) pathway which promotes cell survival and resistance to apoptosis. The aim of this study was to investigate if co-targeting the PI3K pathway can improve the response of BRCA1 mutated cells to PARP-1 inhibition.
Material and methods:, Two BRCA1 and PTEN deficient breast cancer cell lines; MDA-MB-436 and SUM149, were treated with the PARP-1 inhibitor AG14361 (1-(4-dimethylaminomethyl-phenyl)-8-9-dihydro-7H-2,7,9a-benzo[cd]azulen-6-one) and the PI3K inhibitor LY294002 (2-(4-morpholinyl)-8-phenyl-chromone), as single agents and in combination. Cytotoxicity was estimated using the sulpho-rhodamine B assay while cell cycle phase distribution and DNA integrity were analyzed by flow cytometry.
Results: AG14361 induced DNA damage leading to G2/M arrest and decreased viability. LY294002, on the other hand, affected the cell cycle by arresting cells in G1. Importantly, combining AG14361 with LY294002 further decreased survival (P<0.001) with a concomitant decrease in G2/M (P<0.05).
Discussion: This observation may indicate a combination specific up-regulation of apoptosis and suggests that LY294002 potentiates the effects of AG14361. Our results may represent an improved selective targeted treatment strategy for BRCA1 deficient breast cancers and other cancers with DNA damage repair defects and activated PI3K signalling.

Abstract
AIMS To find the optimal cut-off values for cyclin A and Ki67 in early breast cancer tumours and to evaluate their prognostic values. METHODS AND RESULTS Tissue microarray (TMA) slides were constructed from 570 T1-4 N0-1 M0 breast cancer tumours. The TMA slides were stained for cyclin A and Ki67 using immunohistochemistry with commercial antibodies. To investigate the optimal cut-off values for cyclin A, Ki67 average and maximum values the material was split into two parts at cut-offs defined by dividing it into deciles. For each cut-off value the relative risk (RR) for metastasis-free survival (MFS) and overall survival (OS) was calculated comparing patients with high versus low cyclin A or Ki67 expression. When using a cut-off value around the seventh decile, cyclin A and Ki67 score correlated with the highest RR ratio for MFS in the chemotherapy-naïve subgroup. Among patients having received adjuvant chemotherapy, no statistically significant differences in MFS or OS were found. CONCLUSIONS The optimal cut-off value for cyclin A average is 8% and for cyclin A maximum value 11%; for Ki67 the corresponding values are 15% and 22%. Additional studies are needed to verify these results.

Abstract
Cyclin A has in some studies been associated with poor breast cancer survival, although all studies have not confirmed this. Its prognostic significance in breast cancer needs evaluation in larger studies. Tissue microarray (TMA) technique allows a simultaneous analysis of large amount of tumours on a single microscopic slide. This makes a rapid screening of molecular markers in large amount of tumours possible. Because only a small tissue sample of each tumour is punched on an array, the question has arisen about the representativeness of TMA when studying markers that are expressed in only a small proportion of cells. For this reason, we wanted to compare cyclin A expression on TMA and on traditional large sections. Two breast cancer TMAs were constructed of 200 breast tumours diagnosed between 1997–1998. TMA slides and traditional large section slides of these 200 tumours were stained with cyclin A antibody and analysed by two independent readers. The reproducibility of the two readers’ results was good or even very good, with kappa values 0.71–0.87. The agreement of TMA and large section results was good with kappa value 0.62–0.75. Cyclin A overexpression was significantly (P<0.001) associated with oestrogen receptor and progesterone receptor negativity and high grade both on TMA and large sections. Cyclin A overexpression was significantly associated with poor metastasis-free survival both on TMA and large sections. The relative risks for metastasis were similar on TMA and large sections. This study suggests that TMA technique could be useful to study histological correlations and prognostic significance of cyclin A on breast cancer on a large scale.

Abstract
Falling asleep as a means of ending migraine attack was studied in 133 4-16-year-old children in out-patient settings. Children registered 999 migraine attacks in headache diaries using a visual analogue scale (VAS) in 409 attacks and a five-face scale in 590 attacks. The distribution of maximal pain intensity was similar on both scales; on VAS 88% assigned grades between 63 and 100, and on the face scale 93% assigned grades of 4 or 5. Children fell asleep during 33% of the attacks (n = 329), in 64% of these within the first hour (n = 209). Of the children, 68% (n = 91) had fallen asleep at least once during an attack. Falling asleep was more common in children under 8 years of age than in older children. In those under 8 years, 62% (95% confidence interval (CI) 49-75%) of attacks were resolved by sleep, in those aged 8-12 years 34% (26-41%), and in children >12 years 24% (15-33%) (ANOVA, P<0.0001). Pain was relieved without sleep in 43% (n = 431) of attacks, in 38% of these (n = 383) within the first 4 h. The data on migraine resolution were missing for 24% (n = 239) of the attacks, most often because the attack exceeded the 5-h observation period. This study confirms that migraine attacks in children are extremely painful and often resolve during an interval of sleep in children under 8 years of age.
