- Purpose: Since pediatric surgeons aim to follow their patients with anorectal malformations (ARM) into adulthood the aim of this study was to investigate how pediatric surgeons deal with sexual issues related to ARM. Methods: In 2018, a questionnaire was developed by the working group “Follow-up and sexuality” of the ARM-Net consortium and sent to all consortium-linked pediatric surgeons from 31 European pediatric surgical centers. Obtained data were statistically analyzed. Results: Twenty-eight of 37 pediatric surgeons (18 males/10 females) answered the questionnaire. The majority of pediatric surgeons (82%) think they should talk about sexual issues with their patient. More than 50% of pediatric surgeons do not feel at all or only moderately confident discussing the topic of sexuality. Most pediatric surgeons require more support (96%) and wish to be trained in sexuality and sexual issues (78%) to feel confident towards their ARM-patients/parents. For optimal care, sexual issues with ARM-patients should be managed by a multidisciplinary team. Conclusions: Pediatric surgeons feel that sexuality is an important issue for their ARM-patients, which they are primarily responsible of but should be managed in concert with a multidisciplinary team. A training in sexuality is wished to feel more confident about this specific issue.

Disease-related variations of the glycosylation of haptoglobin in the dog
- 1998
-
Ingår i: Journal of Comparative Pathology. - 1532-3129. ; 119:3, s. 227-238
-
Tidskriftsartikel (refereegranskat)abstract
- Haptoglobin phenotypes have been shown in human medicine to be related to the prevalence of various diseases. Furthermore, abnormal glycosylation of haptoglobin has been reported as a consequence of liver disease, cancer and immunological disorders in man. To our knowledge, similar findings have not, so far, been reported in canine disease. The present paper describes a method for investigation of canine haptoglobin phenotypes and of microheterogeneity caused by altered glycosylation. The method consisted of isoelectric focusing (IEF) of dog serum, followed by immunoblotting. The results indicated the existence of only one canine haptoglobin phenotype with a characteristic microheterogeneity pattern in healthy dogs. Changes in this pattern were found in serum from dogs with liver disease, predominantly chronic progressive hepatitis, and with different kinds of anaemia. Pretreatment of serum with neuraminidase or glycopeptidase F (PNGase F) resulted in identical IEF patterns of haptoglobin from healthy and diseased dogs. Moreover, a fucose-specific lectin was capable of binding to some of the abnormal haptoglobin fractions, mainly those found in association with anaemia. The changes described were interpreted as alterations of the carbohydrate content, with or without fucosylation, of some haptoglobin fractions.

Exposed Datapath for Efficient Computing
- 2006
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- We introduce FlexCore, which is the first exemplar of a processor based on the FlexSoC processor paradigm. TheFlexCore utilizes an exposed datapath for increased performance. Microbenchmarks yield a performance boost of a factor of two over a traditional five-stage pipeline with the same functional units as the FlexCore.We describe our approach to compiling for the FlexCore.A flexible interconnect allows the FlexCore datapath to bedynamically reconfigured as a consequence of code generation. Additionally, specialized functional units may be introduced and utilized within the same architecture and compilation framework. The exposed datapath requires a wide control word. The conducted evaluation of two micro benchmarks confirms that this increases the instruction bandwidth and memory footprint. This calls for an efficient instruction decoding as proposed in the FlexSoC paradigm.

Identification of human S100A9 as a novel target for treatment of autoimmune disease via binding to quinoline-3-carboxamides.
- 2009

Tidskriftsartikel (refereegranskat)abstract
- Despite more than 25 years of research, the molecular targets of quinoline-3-carboxamides have been elusive although these compounds are currently in Phase II and III development for treatment of autoimmune/inflammatory diseases in humans. Using photoaffinity cross-linking of a radioactively labelled quinoline-3-carboxamide compound, we could determine a direct association between human S100A9 and quinoline-3-carboxamides. This interaction was strictly dependent on both Zn++ and Ca++. We also show that S100A9 in the presence of Zn++ and Ca++ is an efficient ligand of receptor for advanced glycation end products (RAGE) and also an endogenous Toll ligand in that it shows a highly specific interaction with TLR4/MD2. Both these interactions are inhibited by quinoline-3-carboxamides. A clear structure-activity relationship (SAR) emerged with regard to the binding of quinoline-3-carboxamides to S100A9, as well as these compounds potency to inhibit interactions with RAGE or TLR4/MD2. The same SAR was observed when the compound's ability to inhibit acute experimental autoimmune encephalomyelitis in mice in vivo was analysed. Quinoline-3-carboxamides would also inhibit TNFalpha release in a S100A9-dependent model in vivo, as would antibodies raised against the quinoline-3-carboxamide-binding domain of S100A9. Thus, S100A9 appears to be a focal molecule in the control of autoimmune disease via its interactions with proinflammatory mediators. The specific binding of quinoline-3-carboxamides to S100A9 explains the immunomodulatory activity of this class of compounds and defines S100A9 as a novel target for treatment of human autoimmune diseases.

- Methods currently used for surface display on insect cells and budded baculovirus, all utilize the sequences from class I transmembrane proteins. This gives rise to some problems when handling unknown genes or cDNAs encoding full-length proteins. First, the stop codon from the cloned gene will be located upstream of the sequence for the transmembrane region. Second, the chance of getting the sequences encoding the signal peptide and the transmembrane region in frame with the cloned gene is small. To minimize these problems, we here present a method by which cDNAs or genes of interest can be cloned and fused to the codons for the signal peptide and transmembrane region of neuraminidase (NA), a class II transmembrane protein of the influenza virus. By placing both the signal peptide and transmembrane region at the amino-terminal, potential problems regarding stop codons are eliminated and errors in frame-shift minimized. To obtain proof of principle, the gene encoding enhanced green fluorescent protein, EGFP, was subcloned into a shuttle vector downstream of the neuraminidase sequence and the fusion product was then transferred to a baculovirus vector and transfected into insect cells (Sf9). Using this method, EGFP was found to be expressed on the surface of both infected cells and budded virus in an accessible manner.

Ingår i: Medical Research Archives. - 2375-1916. ; 5:6
-
Tidskriftsartikel (refereegranskat)abstract
- Purpose: The aim of this study was to identify short-term complications after video-assisted gastrostomy in children and to examine the association between complications and underlying disease.Methods: This was a retrospective study at a single institution. Data for all children who underwent video-assisted gastrostomy during 12 years was collected. Complications occurring within three months postoperatively were analyzed.Results: Among 421 children undergoing video-assisted gastrostomy, 402 were included in the study. The median age at surgery was two years (range one month-14 years). The most common underlying disorder was neurological disease (49%). There were two major postoperative complications and 78% had minor complications. Minor complications included granulation tissue (43%), leakage (16%), wound infection (14%), vomiting, dislodgement and pain. There was no significant difference in frequency of the various complications when compared between the underlying diseases (p=0.10-0.82). Wound infection was registered in overall 14% and occurred least frequently in children with neurologic disease and syndromes (10% and 9% respectively).Conclusion: Serious complications after video-assisted gastrostomy are rare, while minor complications occur in 78% of the children. There is no association between the frequency of complications and underlying disease according to this study.

Tidskriftsartikel (refereegranskat)abstract
- Simultaneous contact allergies are common in individuals with photocontact allergy to ketoprofen. The rate of contact allergy to the fragrance substances oxidized linalool and oxidized limonene in ketoprofen-photo-allergic individuals were investigated in comparison with the corresponding rates in individuals without photo-contact allergy to ketoprofen, using Fisher's exact test. A total of 4,021 patients were routinely tested with oxidized linalool; of whom 190 (4.7%) tested positively. For oxidized limonene the numbers were 3,797 patients and 111 positive reactions (2.9%). A total of 19 contact allergic reactions to oxidized linalool were noted in 29 patients (65.5%) who also had photocontact allergy to ketoprofen (p < 0.0001). The corresponding figures for oxidized limonene were 10 positive reactions in 24 ketoprofen-photoallergic individuals (41.7%) (p < 0.0001). Contact allergy to oxidized linalool and/or oxidized limonene is common in routinely tested patients with dermatitis and, particularly, in those patients who are photoallergic to ketoprofen.

Tidskriftsartikel (refereegranskat)abstract
- Background Gastrostomy placement in children is one of the most frequently performed pediatric surgical procedures and laparoscopic-assisted gastrostomy (LAG) is the preferred technique. Wound infection after LAG has become a significant concern due to the emergence of antibiotic resistance. The aim of this study was to describe the frequency of wound infection after LAG in children younger than 2 years of age and to identify the associated risk factors and the bacterial species involved. Methods Information about wound infection, results from bacterial cultures, and type of antibiotic treatment used within 30 postoperative days after LAG were compiled for infants who underwent LAG from 2010 to 2017. A retrospective chart review was performed. Data was compiled from charts and from an electronic database containing prospectively collected data. A multivariate logistic analysis was used to explore potential risk factors. Preoperative antibiotic prophylaxis and postoperative local wound care were conducted according to standard procedures. Results The 141 included infants underwent surgery at a median age of 10 months (range: 1-24). Thirty-eight (27%) patients had a clinically determined wound infection, bacteria were cultured from 26/38 (69%), and 30/38 (79%) received antibiotic treatment. The median interval from surgery to detection of a clinical wound infection was 14 days (range: 4-30). The most common microbes discovered were skin bacteria Staphylococcus aureus or Streptococcus pyogenes , but respiratory and intestinal bacteria were also found. Multivariate logistic regression analysis revealed no independent risk factors for infection such as age, gender, or underlying diagnosis. Conclusion Infants have a high rate of postoperative clinical wound infection after LAG despite the use of preoperative antibiotic prophylaxis and intense local wound care. Gender, age at operation, and previous diagnoses were not found to be independent risk factors for wound infection.
