Determinants of morbidity and mortality following emergency abdominal surgery in children in low-income and middle-income countries
- 2016

Journal article (peer-reviewed)abstract
- Background: Child health is a key priority on the global health agenda, yet the provision of essential and emergency surgery in children is patchy in resource-poor regions. This study was aimed to determine the mortality risk for emergency abdominal paediatric surgery in low-income countries globally.Methods: Multicentre, international, prospective, cohort study. Self-selected surgical units performing emergency abdominal surgery submitted prespecified data for consecutive children aged <16 years during a 2-week period between July and December 2014. The United Nation's Human Development Index (HDI) was used to stratify countries. The main outcome measure was 30-day postoperative mortality, analysed by multilevel logistic regression.Results: This study included 1409 patients from 253 centres in 43 countries; 282 children were under 2 years of age. Among them, 265 (18.8%) were from low-HDI, 450 (31.9%) from middle-HDI and 694 (49.3%) from high-HDI countries. The most common operations performed were appendectomy, small bowel resection, pyloromyotomy and correction of intussusception. After adjustment for patient and hospital risk factors, child mortality at 30 days was significantly higher in low-HDI (adjusted OR 7.14 (95% CI 2.52 to 20.23), p<0.001) and middle-HDI (4.42 (1.44 to 13.56), p=0.009) countries compared with high-HDI countries, translating to 40 excess deaths per 1000 procedures performed.Conclusions: Adjusted mortality in children following emergency abdominal surgery may be as high as 7 times greater in low-HDI and middle-HDI countries compared with high-HDI countries. Effective provision of emergency essential surgery should be a key priority for global child health agendas.

Characteristics of timed barium esophagogram in newly diagnosed idiopathic achalasia: clinical and manometric correlates
- 2007
-
In: Acta Radiol. - : SAGE Publications. - 0284-1851 .- 1600-0455. ; 48:1, s. 2-9

Journal article (peer-reviewed)abstract
- PURPOSE: To describe timed barium esophagogram (TBE) characteristics in patients with newly diagnosed idiopathic achalasia, and to correlate these with clinical and manometric variables. MATERIAL AND METHODS: Forty-six consecutive patients with newly diagnosed achalasia were examined with TBE. Esophageal emptying was assessed using the height, area, and volume of the barium column. Subjective evaluation was performed according to a standardized protocol in all patients. Objective diagnostic evaluation included manometry. RESULTS: At the 1-min time point after contrast ingestion, the static parameters median height, maximum, and mean width of the barium column were 16.0, 4.4, and 3.3 cm, respectively. Emptying, expressed as volume of barium, showed significant inverse correlation with the resting and the maximal relaxing pressure of the lower esophageal sphincter (LES) (R = -0.34 and R = -0.54, respectively). There was also an inverse correlation between emptied volume at TBE and the duration of symptoms (R = -0.36), and between barium column width and postprandial chest pain (R = -0.44). CONCLUSION: All patients with newly diagnosed achalasia presented with delayed emptying of barium the esophagus at TBE. The estimated emptied volume of barium (related to the ingested volume) correlated inversely with the basal tone and the relaxation pressure of the LES. Including estimation of the volume of emptied barium at TBE resulted in closer correlation with manometric values of LES tone than using the parameters traditionally recorded.

Procurement and Evaluation of Hepatocytes for Transplantation From Neonatal Donors After Circulatory Death
- 2022

Journal article (peer-reviewed)abstract
- Hepatocyte transplantation is a promising treatment for liver failure and inborn metabolic liver diseases, but progress has been hampered by a scarcity of available organs. Here, hepatocytes isolated from livers procured for a neonatal hepatocyte donation program within a research setting were assessed for metabolic function and suitability for transplantation. Organ donation was considered for infants who died in neonatal intensive care in the Stockholm region during 2015–2021. Inclusion was assessed when a decision to discontinue life-sustaining treatment had been made and hepatectomy performed after declaration of death. Hepatocyte isolation was performed by three-step collagenase perfusion. Hepatocyte viability, yield, and function were assessed using fresh and cryopreserved cells. Engraftment and maturation of cryopreserved neonatal hepatocytes were assessed by transplantation into an immunodeficient mouse model and analysis of the gene expression of phase I, phase II, and liver-specific enzymes and proteins. Twelve livers were procured. Median warm ischemia time (WIT) was 190 [interquartile range (IQR): 80–210] minutes. Median viability was 86% (IQR: 71%–91%). Median yield was 6.9 (IQR: 3.4–12.8) x106 viable hepatocytes/g. Transplantation into immunodeficient mice resulted in good engraftment and maturation of hepatocyte-specific proteins and enzymes. A neonatal organ donation program including preterm born infants was found to be feasible. Hepatocytes isolated from neonatal donors had good viability, function, and engraftment despite prolonged WIT. Therefore, neonatal livers should be considered as a donor source for clinical hepatocyte transplantation, even in cases with extended WIT.

Communication Enabling the Implementation of Innovation

In: Proceedings of the 29th IRIS. ; , s. 15-
-
Conference paper (peer-reviewed)abstract
- This paper describes the proposed research approach of a research projectcalled, Communication Enabling the Implementation of Innovation. The point of departurefor the project is a view on innovation described as hard work rather than mere creativityor inventions. This leads to the conclusion that innovation processes can be supportedand enhanced through planned activities. The paper promotes a perspective linkinginnovation to the well established concept of a learning organization. The aim for theresearch project is threefold; 1) to generate a method for the development on an indexmeasuring “innovation maturity” of organizations. 2) to generate specific measures ofinnovation processes and 3) to develop a feedback system enhancing the innovativeorganizations towards a learning organization.
