- Purpose: Comorbidity indices are often used to measure comorbidities in register-based research. We aimed to adapt the Charlson comorbidity index (CCI) to a Swedish setting.Methods: Four versions of the CCI were compared and evaluated by disease-specific experts.Results: We created a cohesive coding system for CCI to 1) harmonize the content between different international classification of disease codes (ICD-7,8,9,10), 2) delete incorrect codes, 3) enhance the distinction between mild, moderate or severe disease (and between diabetes with and without end-organ damage), 4) minimize duplication of codes, and 5) briefly explain the meaning of individual codes in writing.Conclusion: This work may provide an integrated and efficient coding algorithm for CCI to be used in medical register-based research in Sweden.

- Proteinase-activated receptors (PARs) are activated by proteolytic removal of a short amino terminal peptide, thus exposing a new amino terminus that functions as a tethered ligand that activates the receptor. With the aim to identify and study potential activators of PAR-2 we have developed a new method to measure proteolytic cleavage of PARs. PAR-2 was tagged with the insulin C-peptide that upon receptor cleavage is released and quantified using an ELISA. The modified receptor, shown to be functional in mouse 3T3 cells, was expressed in an insect cell line and the ability of different proteinases to cleave PAR-2 was studied. Two different mast cell tryptases cleaved PAR-2 in a concentration dependent manner, but were much less potent than pancreatic trypsin and trypsin-2 isolated from a carcinoma cell line. Pancreatic trypsin and trypsin-2 were almost equally effective at cleaving PAR-2 suggesting that extrapancreatic trypsins are potential in vivo activators of PAR-2.

Expression of Cellular Retinoid-Binding Proteins During Normal and Abnormal Epidermal Differentiation
- 1992

- Retinoids have important roles in growth and differentiation of epidermal cells. We have analyzed the expression of two intracellular retinoid-binding proteins, the cellular retinol-binding protein type I and the cellular retinoic acid - binding protein type I, during normal and abnormal epidermal differentiation. Both proteins were found to be expressed in normal epidermis with increasing expression from basal layer towards superficial layers. In psoriatic lesions, a hyperproliferative condition of the skin, the epidermal expression of cellular retinol-binding protein I was induced, whereas expression of cellular retinoic acid-binding protein I was sharply down-regulated. This and other features of psoriatic lesions indicate that down-regulation of cellular retinoic acid - binding protein I expression might cause aberrant retinoid-regulated gene expression in skin. In basal and squamous cell carcinomas, cellular retinoic acid - binding protein I expression was down-regulated, whereas cellular retinol-binding protein I was expressed. Apart from epidermal cells, a mesenchymal, dendritic cell-type, strongly expressing cellular retinoic acid-binding protein I, was identified in the dermis. In several hyperproliferative conditions of the skin, including psoriasis, and squamous and basal cell carcinomas, this cell type was abundant. These results have implications for the role of retinoids in normal and abnormal epidermal differentiation and suggest that part of the phenotype of psoriasis is due to inappropriate metabolism of retinoic acid in skin.

Vascular effects of proteinase-activated receptor 2 agonist peptide

- Proteinase-activated receptor 2 (PAR-2) is a G protein-coupled receptor related to the thrombin receptor. PAR-2 can be activated by trypsin and by synthetic peptides corresponding to the new amino terminus generated by activating proteolytic cleavage. We show in this report that intravenous injection of PAR-2 agonist peptides has dramatic effects on arterial blood pressure in anesthetized rats. The peptide SLIGRLETQPPI, at 150 nmol/kg, transiently decreased the mean arterial pressure from 104 to 60 mm Hg. The hypotensive response was dose-dependent, and was not secondary to effects on central vasoregulatory systems, heart rate, or the kidneys. A nitric oxide synthase inhibitor attenuated the hypotensive response induced by the PAR-2 agonist peptide. Further experiments in vitro, on preparations of rat femoral artery and vein, showed that PAR-2 agonist peptide elicited a dose-dependent relaxation of both types of vessel. Removal of the endothelium abolished the agonist peptide-induced relaxation. Our results demonstrate that activation of PAR-2 can modulate vascular tone, and that this response was an effect mediated at least partly by nitric oxide. The effect on blood vessels further suggests that the physiological activator of this proteolytically activated receptor is an enzyme present and active in the blood, possibly after a vascular injury.

Sustainable Production by Integrating Business Models of Manufacturing and Recycling Industries

Konferensbidrag (refereegranskat)abstract
- Future raw material shortage, high price levels and environmental regulations requires increased reuse of materials andcomponents. This will substantially influence conditions for both manufacturing and recycling industries, which need toinnovate their business models. Our hypothesis is that an integrated co-operation between organizations within these industries, employing symbiotic business models will increase the profitability and reduce the total environmental impact. Findings from interaction with manufacturing and recycling industries using a business model framework as baseline are presented. Results indicate that profit and decreased environmental effects can be achieved through symbiotic business models, but further development and implementation is needed.

NeuroMotion Smartphone Application for Remote General Movements Assessment : a Feasibility Study in Nepal

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: To evaluate the feasibility of using the NeuroMotion smartphone application for remote General Movements Assessment for screening of infants for cerebral palsy in Kathmandu, Nepal. METHOD: Thirty-one term born infants at risk of cerebral palsy due to birth asphyxia or neonatal seizures were recruited for the follow-up at Paropakar Maternity and Women’s Hospital, 1st October 2021 to 7th January 2022. Parents filmed their children at home using the app at 3 months’ age and the videos were assessed for technical quality using a standardized form and for fidgety movements by Prechtl’s General Movements Assessment. Usability of the app was evaluated through a parental survey. RESULTS: Twenty families sent in altogether 46 videos out of which 35 had approved technical quality. Sixteen children had at least one video with approved technical quality. Three infants lacked fidgety movements. The level of agreement between assessors was acceptable (Krippendorf alpha 0.781). Parental answers to the usability survey were in general positive. INTERPRETATION: Engaging parents in screening of cerebral palsy with the help of a smartphone-aided remote General Movements Assessment is possible in the urban area of a South Asian lower middle-income country.

- A bovine adrenal cDNA library was constructed and a clone corresponding to cellular retinoic-acid-binding protein (CRABP) mRNA was isolated and sequenced. The insert of the clone corresponds to 75 bp of the 5′ untranslated portion, the whole translated and the complete 3′ untranslated portion of the bovine CRABP mRNA. A genomic Southern blot, probed with CRABP cDNA, indicated that only one copy of the gene is present in the human genome. Hybridizing bands in restricted chicken and fish DNA were also observed. Using the CRABP cDNA as probe we have located the human CRABP gene to chromosome 3 in hybridizations to mouse-human, hamster-human and rat-human cell hybrids. In situ hybridizations on rat testis cells probed with CRABP and cellular retinol-binding protein antisense mRNA indicate that both proteins are expressed in tubuli cells.
