- Människors säkerhet handlar om mycket mer än det rent militära. Därför är det är dags att överväga att införa allmän medborgartjänst för alla medborgare kring tjugoårsåldern.

- The Visual Analogue Scale for Irritable Bowel Syndrome (VAS-IBS), a self-rating questionnaire, was designed to measure symptoms and the effect of treatment in patients suffering from irritable bowel syndrome. The aim of this descriptive correlational study was to conduct further psychometric validation after the VAS-IBS had been used in clinical practice, translate it into English, and compare the results with controls. Forty-nine patients with irritable bowel syndrome (median age = 38 years old [range, 18-69 years]) were compared with 90 healthy persons (median age = 44 years old [range, 21-77 years]) who served as controls. The patients with irritable bowel syndrome completed 3 questionnaires: the VAS-IBS, the Gastrointestinal Symptom Rating Scale, and the Perception of Change of Symptoms. Controls completed only the VAS-IBS. Results showed that the VAS-IBS is a valid questionnaire that measures the degree of change of symptoms and discriminates between patients who have irritable bowel syndrome from those who do not. It is important to compare the VAS-IBS among different cultural populations so we suggest that the English version of the VAS-IBS should now be used in English-speaking countries and be further tested for validity and reliability with English-speaking patients.

Lifetime versus Annual Tax-and-Transfer Progressivity : Sweden, 1968-2009

- In this paper, we analyze the evolution of tax-and-transfer progressivity in Sweden over both annual and lifetime horizons. Using a rich micro panel covering the period 1968-2009, we calculate tax rates over a cohort's entire working life cycle. Our main finding is that taxes are considerably less progressive over the lifetime than in any single year. Social insurance transfers to transitory low-income earners account for most of this result. We offer a number of robustness checks of the measurement of lifetime incomes and progressivity, but none of them changes our overall findings.

- Abstract. Purpose: To compare the performance of two machine learning classifiers (MLCs), artificial neural networks (ANNs) and support vector machines (SVMs), with input based on retinal nerve fibre layer thickness (RNFLT) measurements by optical coherence tomography (OCT), on the diagnosis of glaucoma, and to assess the effects of different input parameters. Methods: We analysed Stratus OCT data from 90 healthy persons and 62 glaucoma patients. Performance of MLCs was compared using conventional OCT RNFLT parameters plus novel parameters such as minimum RNFLT values, 10th and 90th percentiles of measured RNFLT, and transformations of A-scan measurements. For each input parameter and MLC, the area under the receiver operating characteristic curve (AROC) was calculated. Results: There were no statistically significant differences between ANNs and SVMs. The best AROCs for both ANN (0.982, 95%CI: 0.966-0.999) and SVM (0.989, 95% CI: 0.979-1.0) were based on input of transformed A-scan measurements. Our SVM trained on this input performed better than ANNs or SVMs trained on any of the single RNFLT parameters (p

- BackgroundRandomized controlled trials relatively consistently show that restrictive red blood cell (RBC) transfusion strategies are safe and associated with similar outcomes compared to liberal transfusion strategies in critically ill patients. Based on these data, the general threshold for RBC transfusion was changed to 70 g/L at a 9-bed tertiary level intensive care unit in September 2020. Implementation measures included lectures, webinars and feedback during clinical practice. The aim of this study was to investigate how implementation of a restrictive transfusion strategy influenced RBC usage, haemoglobin trigger levels and adherence to prescribed trigger levels.MethodsIn this registry-based, observational study, critically ill adult patients without massive bleeding were included and divided into a pre-cohort, with admissions prior to the change of transfusion strategy, and a post-cohort, with admissions following the change of transfusion strategy. These cohorts were compared regarding key RBC transfusion-related variables.ResultsIn total 5626 admissions were included in the analyses (pre-cohort n = 4373, post-cohort n = 1253). The median volume (interquartile range, IQR) of RBC transfusions per 100 admission days, in the pre-cohort was 6120 (4110–8110) mL versus 3010 (2890–4970) mL in the post-cohort (p < .001). This corresponds to an estimated median saving of 1128 € per 100 admission days after a restrictive RBC transfusion strategy was implemented. In total, 26% of the admissions in the pre-cohort and 19% in the post-cohort (p < .001) received RBC transfusion(s) during days 0–10. Both median (IQR) prescribed trigger levels (determined by intensivist) and actual haemoglobin trigger levels (i.e., levels prior to actual administration of transfusion) were higher in the pre- versus post-cohort (90 [80–100] vs. 80 [72–90] g/L, p < .001 and 89 [82–96] g/L vs. 83 [79–94], p < .001, respectively). Percentage of days without compliance with the prescribed transfusion trigger was higher in the pre-cohort than in the post-cohort (23% vs. 14%, p < .001). Sensitivity analyses, excluding patients with traumatic brain injury, ischemic heart disease and COVID-19 demonstrated similar results.ConclusionsImplementation of a restrictive transfusion trigger in a critical care setting resulted in lasting decreased RBC transfusion use and costs, decreased prescribed and actual haemoglobin trigger levels and improved adherence to prescribed haemoglobin trigger levels.

Tidskriftsartikel (refereegranskat)abstract
- A robust and relatively compact calibration-free thermometric technique using diode lasers two-line atomic fluorescence (TLAF) for reactive flows at atmospheric pressures is investigated. TLAF temperature measurements were conducted using indium and, for the first time, gallium atoms as temperature markers. The temperature was measured in a multi-jet burner running methane/air flames providing variable temperatures ranging from 1600 to 2000 K. Indium and gallium were found to provide a similar accuracy of ~ 2.7% and precision of ~ 1% over the measured temperature range. The reliability of the TLAF thermometry was further tested by performing simultaneous rotational CARS measurements in the same experiments.
