- Aim. The aim was to explore the relationships between the feelings of women who give birth and several birth-related care conditions, the womens' socio-demographic background, personality and perceptions of the quality of intrapartum care. Background. Childbirth is a highly significant emotional event for women and it is an explicit goal that each woman should have a positive childbirth experience. Design. The nationwide study is cross-sectional and was conducted at Swedish maternity units over two months in 2007. Methods. The study group consisted of 739 women (63% response rate). A dimensionality analysis of six emotion items was performed using structural equation modelling (SEM). Non-parametric tests and generalised linear mixed effects model analyses were used to study relationships and to make subgroup comparisons. Results. In the SEM analysis, a positive and a negative feeling factor were identified. Strong associations between the feeling factors and the womens' perceptions of the quality of care were found, particularly in regard to the so-called identity-oriented approach of the midwives and other health professionals. In addition, a higher intensity of negative feelings was associated with a personality pattern characterised by extraversion, emotional instability and lower degree of conscientiousness, a lower level of education and having had delivery through Caesarean section. Conclusions. The positive and negative feelings of women who give birth strongly covary with the women's perception of the quality of their intrapartum care. This pertains in particular to information issues, the midwives showing commitment, empathy and respect, being present during labour and allowing the women to actively participate as much as they want to. Relevance to clinical practice. Subgroup differences indicate that midwives should pay increased attention to childbearing women who have primary school education only, a lower emotional stability and/or deliver through Caesarean section.

- Aim.To develop a patient questionnaire specific to intrapartal care, based on the theoretical foundation of the general instrument Quality from the Patient's Perspective (QPP).Background.Existing general patient questionnaires do not take intrapartal care aspects fully into account, and available intrapartal-specific patient questionnaires tend to have a weak theoretical foundation.Design.A cross-sectional, nationwide study carried out during a two-week period in 2007 at Swedish maternity units.Method.An intrapartal-specific QPP-questionnaire (QPP-I) was developed by combining a selection of 22 items from the short and long versions of the QPP with 10 newly constructed items. Responses were obtained from 739 women (63% response rate). The dimensionality of the QPP-I was assessed using structural equation modelling (a nested factor model). Non-parametric statistics were used for subgroup comparisons.Results.A nested model with a general factor including all 32 items and 10 subordinate factors was developed. Most scales had acceptable reliability coefficients (0 center dot 73-0 center dot 93), and a meaningful pattern of subgroup differences was obtained.Conclusions.The QPP-I is theory based and has its roots in a patient perspective. It was developed using a nationwide sample of Swedish women receiving intrapartal care, and an advanced statistical method was used. The outcome of this initial empirical trial was promising but needs to be tested in different countries and cultures.Relevance to clinical practice.By combining womens' responses on perceived reality and subjective importance ascribed to the various aspects of care measured, the QPP-I offers the care provider better guidelines on which elements to focus quality improvement work on, than would be the case if only a rank order of perceived reality ratings was available.

- Despite advances in the molecular exploration of paediatric cancers, approximately 50% of children with high-risk neuroblastoma lack effective treatment. To identify therapeutic options for this group of high-risk patients, we combine predictive data mining with experimental evaluation in patient-derived xenograft cells. Our proposed algorithm, TargetTranslator, integrates data from tumour biobanks, pharmacological databases, and cellular networks to predict how targeted interventions affect mRNA signatures associated with high patient risk or disease processes. We find more than 80 targets to be associated with neuroblastoma risk and differentiation signatures. Selected targets are evaluated in cell lines derived from high-risk patients to demonstrate reversal of risk signatures and malignant phenotypes. Using neuroblastoma xenograft models, we establish CNR2 and MAPK8 as promising candidates for the treatment of high-risk neuroblastoma. We expect that our method, available as a public tool (targettranslator.org), will enhance and expedite the discovery of risk-associated targets for paediatric and adult cancers.

- Cancer patients often suffer from cancer symptoms, treatment complications and concomitant diseases and are, therefore, often treated with several drugs in addition to anticancer drugs. Whether such drugs, here denoted as 'concomitant drugs', have anticancer effects or interact at the tumor cell level with the anticancer drugs is not very well known. The cytotoxic effects of nine concomitant drugs and their interactions with five anti-cancer drugs commonly used for the treatment of colorectal cancer were screened over broad ranges of drug concentrations in vitro in the human colon cancer cell line HCT116wt. Seven additional tyrosine kinase inhibitors were included to further evaluate key findings as were primary cultures of tumor cells from patients with colorectal cancer. Cytotoxic effects were evaluated using the fluorometric microculture cytotoxicity assay (FMCA) and interaction analysis was based on Bliss independent interaction analysis. Simvastatin and loperamide, included here as an opioid agonists, were found to have cytotoxic effects on their own at reasonably low concentrations whereas betamethasone, enalapril, ibuprofen, metformin, metoclopramide, metoprolol and paracetamol were inactive also at very high concentrations. Drug interactions ranged from antagonistic to synergistic over the concentrations tested with a more homogenous pattern of synergy between simvastatin and protein kinase inhibitors in HCT116wt cells. Commonly used concomitant drugs are mostly neither expected to have anticancer effects nor to interact significantly with anticancer drugs frequently used for the treatment of colorectal cancer.

Tidskriftsartikel (refereegranskat)abstract
- We recently showed that the anti-helminthic compound mebendazole (MBZ) has immunomodulating activity in monocyte/macrophage models and induces ERK signalling. In the present study we investigated whether MBZ induced ERK activation is shared by other tubulin binding agents (TBAs) and if it is observable also in other human cell types. Curated gene signatures for a panel of TBAs in the LINCS Connectivity Map (CMap) database showed a unique strong negative correlation of MBZ with MEK/ERK inhibitors indicating ERK activation also in non-haematological cell lines. L1000 gene expression signatures for MBZ treated THP-1 monocytes also connected negatively to MEK inhibitors. MEK/ERK phosphoprotein activity testing of a number of TBAs showed that only MBZ increased the activity in both THP-1 monocytes and PMA differentiated macrophages. Distal effects on ERK phosphorylation of the substrate P90RSK and release of IL1B followed the same pattern. The effect of MBZ on MEK/ERK phosphorylation was inhibited by RAF/MEK/ERK inhibitors in THP-1 models, CD3/IL2 stimulated PBMCs and a MAPK reporter HEK-293 cell line. MBZ was also shown to increase ERK activity in CD4+ T-cells from lupus patients with known defective ERK signalling. Given these mechanistic features MBZ is suggested suitable for treatment of diseases characterized by defective ERK signalling, notably difficult to treat autoimmune diseases.

- BACKGROUND: Symptoms of attention deficit hyperactivity disorder (ADHD) are more common in children with epilepsy than in the general paediatric population. Epileptiform discharges in EEG may be seen in children with ADHD also in those without seizure disorders. Sleep enhances these discharges which may be suppressed by levetiracetam. AIM: To assess the effect of levetiracetam on focal epileptiform discharges during sleep in children with ADHD. METHOD: In this retrospective study a new semi-automatic quantitative method based on the calculation of spike index in 24-h ambulatory EEG recordings was applied. Thirty-five ADHD children, 17 with focal epilepsy, one with generalised epilepsy, and 17 with no seizure disorder were evaluated. Follow-up 24-h EEG recordings were performed after a median time of four months. RESULTS: Mean spike index was 50 prior to levetiracetam treatment and 21 during treatment. Seventeen children had no focal interictal epileptiform discharges in EEG at follow-up. Five children had a more than 50% reduction in spike index. Thus, a more than 50% reduction in spike index was found in 22/35 children (63%). Out of these an improved behaviour was noticed in 13 children (59%). CONCLUSION: This study shows that treatment with levetiracetam reduces interictal epileptiform discharges in children with ADHD. There is a complex relationship between epilepsy, ADHD and epileptiform activity, why it is a need for prospective studies in larger sample sizes, also to ascertain clinical benefits.

- Porous resorbable implants are of great interest since they may deliver bioactives or drugs, facilitate the transport of body fluids or degradation products and provide a favorable environment for cell attachment and growth. In this work we report on a method using concentrated emulsions to template interconnected solid foam materials and to produce highly porous poly(3-hydroxybutyrate) (PHB) materials. Porous PHB films were cast made from water-in-oil template emulsions including Span 80 and lithium sulphate. The films were characterized by SEM-EDX and DMA. The water uptake of the films was recorded in order to determine the fraction water available pores. The results show that the ad-dition of lithium sulphate allows a fine tuning of the film morphology with respect to porosity and interconnected po-rous structure. The film porosity was determined to 51% ± 3%, 52% ± 3% and 45% ± 3% for the films made with 0%, 2.9% and 14.3% lithium sulphate in the template emulsion, respectively. The fraction water available pores was sig-nificantly lower, 11% ±3%, 38% ±12% and 48% ± 7% for films with 0%, 2.9% and 14.3% litium sulphate respectively. Differences in fraction water available pores and total porosity for the films reflects the film morphology and differ-ences in pore interconnection.
