- INTRODUCTION: Induction of labor is increasing in the world. A common indication for Induction of labor is late term and postterm pregnancy at 41 gestational week and thereafter. We aimed to evaluate if there are any differences regarding efficacy, safety, and women's childbirth experience between oral misoprostol and transvaginal balloon catheter for cervical ripening in women with a low-risk singleton pregnancy and induction of labor at 41+0 to 42+0-1 gestational weeks.MATERIAL AND METHODS: In this observational study, based on data from Swedish Postterm Induction Study (SWEPIS), a multicenter randomized controlled trial, a total of 1 213 women with a low-risk singleton pregnancy at 41 to 42 gestational weeks were induced with oral misoprostol (n=744) or transvaginal balloon catheter (n=469) at 15 Swedish delivery hospitals. The primary efficacy outcome was vaginal delivery within 24 hours and primary safety outcomes were neonatal and maternal composite adverse outcomes. Secondary outcomes included time-to-vaginal delivery and mode of delivery. Women's childbirth experience was assessed with the Childbirth Experience Questionnaire (CEQ 2.0) and visual analogue scale. We present crude and adjusted mean differences and relative risks (RR) with 95% confidence interval (CI). Adjustment was performed for a propensity score based on delivery hospital and baseline characteristics including Bishop score.RESULTS: Vaginal delivery within 24 hours was significantly lower in the misoprostol compared with the balloon catheter group (46.5% [346/744] vs 62.7% [294/469]; adjusted RR 0.76 [95% CI 0.64; 0.89]). Primary neonatal and maternal safety outcomes did not differ between groups (neonatal composite 3.5% [36/744] vs 3.2% [15/469]; adjusted RR 0.77 [95% CI 0.31; 1.89]; maternal composite (2.3% [17/744] vs 1.9% [9/469]; adjusted RR 1.70 [95% CI 0.58; 4.97]). Adjusted mean time-to-vaginal delivery was increased by 3.8 hours (95% CI 1.3; 6.2) in the misoprostol group. Non-operative vaginal delivery and cesarean delivery rates did not differ. Women's childbirth experience was positive overall and similar in both groups.CONCLUSION: Induction of labor with oral misoprostol compared with a transvaginal balloon catheter was associated with a lower probability of vaginal delivery within 24 hours and a longer time-to-vaginal delivery. However, primary safety outcomes, non-operative vaginal delivery and women's childbirth experience were similar in both groups. Therefore, both methods can be recommended in women with low-risk postdate pregnancies.

- Objective: To assess the cost-effectiveness of induction of labour (IOL) at 41weeks of gestation compared with expectant management until 42weeks of gestation. Design: A cost-effectiveness analysis alongside the Swedish Post-term Induction Study (SWEPIS), a multicentre, randomised controlled superiority trial. Setting: Fourteen Swedish hospitals during 2016–2018. Population: Women with an uncomplicated singleton pregnancy with a fetus in cephalic position were randomised at 41weeks of gestation to IOL or to expectant management and induction at 42weeks of gestation. Methods: Health benefits were measured in life years and quality-adjusted life years (QALYs) for mother and child. Total cost per birth was calculated, including healthcare costs from randomisation to discharge after delivery, for mother and child. Incremental cost-effectiveness ratios (ICERs) were calculated by dividing the difference in mean cost between the trial arms by the difference in life years and QALYs, respectively. Sampling uncertainty was evaluated using non-parametric bootstrapping. Main outcome measures: The cost per gained life year and per gained QALY. Results: The differences in life years and QALYs gained were driven by the difference in perinatal mortality alone. The absolute risk reduction in mortality was 0.004 (from 6/1373 to 0/1373). Based on Swedish life tables, this gives a mean gain in discounted life years and QALYs of 0.14 and 0.12 per birth, respectively. The mean cost per birth was €4108 in the IOL group (n=1373) and €4037 in the expectant management group (n=1373), with a mean difference of €71 (95%CI −€232 to €379). The ICER for IOL compared with expectant management was €545 per life year gained and €623 per QALY gained. Confidence intervals were relatively wide and included the possibility that IOL had both lower costs and better health outcomes. Conclusions: Induction of labour at 41weeks of gestation results in a better health outcome and no significant difference in costs. IOL is cost-effective compared with expectant management until 42weeks of gestation using standard threshold values for acceptable cost per life year/QALY. Tweetable abstract: Induction of labour at 41weeks of gestation is cost-effective compared with expectant management until 42weeks of gestation.

- Eosinophils have been linked to functional dyspepsia; however, less is known about their role in irritable bowel syndrome (IBS). This study tested the hypothesis of alterations in levels of fecal eosinophil-derived neurotoxin (F-EDN) and eosinophil density and degranulation within the colonic mucosa of IBS patients compared with healthy controls (HC). Colonic biopsies were collected from 37 IBS patients and 20 HC and analyzed for eosinophil numbers and local degranulation of eosinophil cationic protein (ECP) by histologic procedures. Fecal samples were collected for F-EDN and microbiota analysis. Differentiated 15HL-60 cells were used in vitro to investigate the direct effect of live bacteria on eosinophil activation measured by a colorimetric assay with o-phenylenediamine (OPD) substrate. We observed a higher number of eosinophils and increased extracellular ECP in the mucosa of IBS patients compared with HC. Moreover, F-EDN levels in IBS samples were elevated compared with HC and positively correlated to extracellular ECP. Metagenomic analysis showed significant correlations between bacterial composition and eosinophil measurements in both HC and IBS patients. In vitro experiments revealed an increased degranulation of 15HL-60 after stimulation with Salmonella typhimurium, Salmonella enterica, and Yersinia enterocolitica. To conclude, we could demonstrate alterations related to eosinophils in IBS, and, for the first time, a positive correlation between F-EDN levels and degranulated eosinophils in the colonic mucosa of IBS patients. Together our results suggest that eosinophils play a role in the pathophysiology of IBS and the mechanisms might be linked to an altered microbiota.

- Objectives: Pectus excavatum, or funnel chest, causes both physical and psychosocial issues, affecting health-related quality of life. However, the literature on how funnel chest affects daily living prior to corrective surgery is sparse. Therefore, the study aimed to describe the experiences of living with funnel chest prior to correctional surgery.Materials and methods: The study had a qualitative exploratory design. Consecutive sampling was applied in which all individuals from a single cardiothoracic department scheduled for the minimally invasive repair of pectus excavatum were asked to participate. Nineteen participants, 17 men and two women, participated in the study. Individual telephone interviews were conducted from February 2020 until April 2021. The interviews were analyzed with qualitative content analysis using an inductive approach.Results: The overall theme "To have or not to have a cavity in my chest, it could make a difference" was interpreted as the latent meaning of the participants' experiences. The theme included two subthemes with three categories each. The subtheme "The funnel chest puts a weight on my shoulders" describes the heavy burden the funnel chest places on the participants. The second subtheme, "This is me, but I want to change my future", describes that participants see the funnel chest as a part of themselves; nevertheless, they look forward to surgery and a life without it.Conclusion: The results emphasize the heavy burden funnel chest causes and the great limitations it places on the individual. It also highlights the importance of surgery and the hope for a better future for individuals with funnel chest.

- OBJECTIVES: Pectus excavatum (PE) can cause both physical and psychosocial symptoms and affect patients' health-related quality of life. Previous international studies have shown that the Nuss procedure increases both self-esteem and body image. The aim of the study was to evaluate the health-related quality of life in patients who have undergone the Nuss procedure for PE.METHODS: The study had a cross-sectional multicentre design. All patients (N = 420) who underwent the Nuss procedure for PE in 3 cardiothoracic departments in Sweden from 2000 to 2019 were invited to answer the RAND-36 and Nuss Questionnaire modified for adults. Genders were compared using the Mann-Whitney U-test. Patients were divided into groups based on age at time of surgery (<20, 20-30 or >30 years) and analysed by the Kruskal-Wallis H-test with post-hoc analyses.RESULTS: A total of 236 patients returned the questionnaires; 82.2% were males. Men scored significantly better on the modified Nuss Questionnaire total (P = 0.01) and psychosocial (P = 0.02) subscales. Patients who had surgery at <20 years of age had significantly better scores on the same scales (P = 0.007 and 0.006, respectively) compared to patients aged 20-30 years at the time of surgery. However, no significant difference was seen in comparison with patients >30 years. Patients who had their bar removed had significantly better values on both scales.CONCLUSIONS: Male gender, young age at surgery and bar removal seem to be associated with better health-related quality of life after the Nuss procedure for PE.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Pectus excavatum (PE) is the most common congenital chest wall deformity. Most individuals with PE suffer from psychosocial problems, with low self-esteem and poor body image. Correctional surgery for PE is available, the most widely used is the Nuss procedure. The Nuss procedure has previously been reported to improve self-esteem, body image and health-related quality of life (HRQoL). To assess HRQoL among individuals with PE, the Nuss Questionnaire modified for Adults (NQ-mA) and Single Step Questionnaire (SSQ) has been developed. The aim of the current study was to translate and culturally adapt NQ-mA and SSQ to fit a Swedish context, and to evaluate the psychometric properties, and validate the culturally adapted versions.METHODS: Individuals who had undergone the Nuss procedure for pectus excavatum were invited to participate in a multicentre study with cross-sectional design. HRQoL was assessed by NQ-mA, SSQ and RAND-36. Psychometric properties for NQ-mA and SSQ were evaluated by content validity index and construct validity (exploratory factor analysis, confirmatory factor analysis, and inter-scale correlations). Known-groups validity, as well as floor and ceiling effects, were evaluated. Internal consistency reliability was examined using Cronbach's alpha.RESULTS: In total 236 individuals participated in the study. Content validity index for NQ-mA showed satisfactory results, except for two items. Factor analysis for NQ-mA suggested a two-factor model, with exclusion of two items. Subscales correlated adequately with RAND-36's domains. Known-groups validity for NQ-mA demonstrated high sensitivity for between-group differences. Ceiling effects were present in several items. Cronbach's alpha for NQ-mA was .89. Confirmatory factor analysis for SSQ resulted in a three-factor model, with exclusion of five items. However, this model was shown to be unstable through further exploratory factor analysis testing, and no further psychometric tests were conducted for SSQ.CONCLUSION: The 10-item Swedish version of NQ-mA was shown to be valid for research and clinical assessment of HRQoL in individuals with pectus excavatum. The Swedish version of SSQ requires revision of items before further validation can be performed.

- The interpretation of nuclear magnetic resonance (NMR) data is of interest in a number of fields. In Ögren [Eur. Phys. J. B (2014) 87: 255] local boundary conditions for random walk simulations of NMR relaxation in digital domains were presented. Here, we have applied those boundary conditions to large, three-dimensional (3D) porous media samples. We compared the random walk results with known solutions and then applied them to highly structured 3D domains, from images derived using synchrotron radiation CT scanning of North Sea chalk samples. As expected, there were systematic errors caused by digitalization of the pore surfaces so we quantified those errors, and by using linear local boundary conditions, we were able to significantly improve the output. We also present a technique for treating numerical data prior to input into the ESPRIT algorithm for retrieving Laplace components of time series from NMR data (commonly called T-inversion).
