  • Characterizing prostate cancer risk through multi-ancestry genome-wide discovery of 187 novel risk variants
  • 2023
  • Ingår i: Nature Genetics. - : Springer Nature. - 1061-4036 .- 1546-1718. ; 55:12, s. 2065-2074
  • Tidskriftsartikel (refereegranskat)abstract
    • The transferability and clinical value of genetic risk scores (GRSs) across populations remain limited due to an imbalance in genetic studies across ancestrally diverse populations. Here we conducted a multi-ancestry genome-wide association study of 156,319 prostate cancer cases and 788,443 controls of European, African, Asian and Hispanic men, reflecting a 57% increase in the number of non-European cases over previous prostate cancer genome-wide association studies. We identified 187 novel risk variants for prostate cancer, increasing the total number of risk variants to 451. An externally replicated multi-ancestry GRS was associated with risk that ranged from 1.8 (per standard deviation) in African ancestry men to 2.2 in European ancestry men. The GRS was associated with a greater risk of aggressive versus non-aggressive disease in men of African ancestry (P = 0.03). Our study presents novel prostate cancer susceptibility loci and a GRS with effective risk stratification across ancestry groups.

  • Inflammatory response and platelet activation after off-pump coronary artery bypass surgery.
  • 2006
  • Ingår i: Scandinavian cardiovascular journal : SCJ. - : Informa UK Limited. - 1401-7431 .- 1651-2006. ; 40:1, s. 43-8
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Cardiac surgery induces a systemic inflammatory activation and alterations in the hemostatic cascade. The responses contribute to postoperative complications but may also have protective effects. We investigated the relationship between inflammation, hemostasis and bleeding after off-pump coronary artery bypass surgery (OPCAB). METHODS: Ten OPCAB patients were included in a prospective descriptive study. Selected markers of inflammation (IL-6, IL-8, PMN-elastase, C3a, and SC5b-9), and hemostasis (platelet count, ss-thromboglobulin, anti-thrombin, D-dimer and fibrinogen) were measured before and immediately after surgery. Postoperative bleeding was registered. RESULTS: Inflammatory variables did not alter significantly during surgery while ss-thromboglobulin concentrations increased and anti-thrombin and fibrinogen decreased. There were significant postoperative correlations between PMN-elastase and ss-thromboglobulin (r=0.82, p=0.004), between PMN-elastase and fibrinogen (r=0.69, p=0.03) and between C3a and ss-thromboglobulin (r=0.71, p=0.02). In addition, there were significant inverse correlations between postoperative bleeding and pre- and postoperative fibrinogen levels (r=-0.76, p=0.011 and r=-0.84, p=0.002 respectively), between bleeding and postoperative ss-thromboglobulin levels (r=-0.66, p=0.04) and between bleeding and postoperative PMN-elastase (r=-0.75, p=0.01). CONCLUSIONS: The results give further evidence for an association between the inflammatory response and hemostasis after cardiac surgery.

  • Impact of spinal cord malformation on bladder function in children with anorectal malformations.
  • 2009
  • Ingår i: Journal of pediatric surgery. - : Elsevier BV. - 1531-5037 .- 0022-3468. ; 44:9, s. 1778-85
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: Risk factors for the presence of neurogenic bladder dysfunction (NBD) in children born with high anorectal malformations (ARMs), were investigated, to identify the need for urodynamics in these patients. MATERIAL AND METHODS: The study included 37 patients with high ARMs (21 boys and 16 girls). Bladder function was evaluated with urodynamics both before and after anorectoplasty (posterior sagittal anorectoplasty [PSARP]). All patients were investigated with spinal radiograph. Spinal ultrasound was performed in the neonatal period, and magnetic resonance imaging was added in case of abnormal ultrasound or urodynamics and in case of cloacal malformation. RESULTS: In ARM patients with rectourethral and vestibular fistulas and cloacas, NBD was identified in 9 children (25%). The bladder dysfunction was innate in all cases except in one girl with cloaca, indicating that the risk of iatrogenic denervation seems minimal using the PSARP technique. All children with innate NBD had a spinal cord malformation either as spinal cord regression or tethering with or without a lipoma. Concerning vertebral status, almost all children with NBD had partial sacral agenesis. Abnormal perineal appearance was highly correlated to NBD in boys, especially in those with a spinal cord regression malformation. Innate NBD was not found in any child with normal spinal cord. CONCLUSION: From these results, we suggest that spinal ultrasound and perineal inspection are used as screening procedures for NBD in children with ARM. Urodynamic investigation is recommended only when spinal cord anomalies or other signs indicative of NBD are present. In case of spinal cord malformation, repeated urodynamics during follow-up is mandatory because of the risk for developing tethered cord syndrome.

  • Verbal and non-verbal function of children with right- versus left-hemiplegic cerebral palsy of pre- and perinatal origin.
  • 1994
  • Ingår i: Developmental medicine and child neurology. - 0012-1622. ; 36:6, s. 503-12
  • Tidskriftsartikel (refereegranskat)abstract
    • Eighteen children with right- and 13 with left-sided congenital hemiplegia were compared with 19 normal age-matched controls for verbal and non-verbal function. CT scans were obtained from 27 of the 31 hemiplegic children. The two hemiplegic groups were impaired in non-verbal function compared with controls. The right-hemiplegic group was more impaired in verbal function than the left-hemiplegic group and controls; however, impairments were restricted to the girls in the right-hemiplegic group. The results are discussed in terms of cerebral plasticity and functional reorganisation of cognitive functions after an early unilateral injury. It is argued that girls with left-hemisphere lesions may be more limited in cerebral plasticity than boys.

  • Guidelines for perioperative care after radical cystectomy for bladder cancer : enhanced Recovery After Surgery (ERAS(®)) society recommendations
  • 2013
  • Ingår i: Clinical Nutrition. - Edinburgh, UK : Churchill-Livingstone. - 0261-5614 .- 1532-1983. ; 32:6, s. 879-887
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: Enhanced recovery after surgery (ERAS) pathways have significantly reduced complications and length of hospital stay after colorectal procedures. This multimodal concept could probably be partially applied to major urological surgery.OBJECTIVES: The primary objective was to systematically assess the evidence of ERAS single items and protocols applied to cystectomy patients. The secondary objective was to address a grade of recommendation to each item, based on the evidence and, if lacking, on consensus opinion from our ERAS Society working group.EVIDENCE ACQUISITION: A systematic literature review was performed on ERAS for cystectomy by searching EMBASE and Medline. Relevant articles were selected and quality-assessed by two independent reviewers using the GRADE approach. If no study specific to cystectomy was available for any of the 22 given items, the authors evaluated whether colorectal guidelines could be extrapolated.EVIDENCE SYNTHESIS: Overall, 804 articles were retrieved from electronic databases. Fifteen articles were included in the present systematic review and 7 of 22 ERAS items were studied. Bowel preparation did not improve outcomes. Early nasogastric tube removal reduced morbidity, bowel recovery time and length of hospital stay. Doppler-guided fluid administration allowed for reduced morbidity. A quicker bowel recovery was observed with a multimodal prevention of ileus, including gum chewing, prevention of PONV and minimally invasive surgery.CONCLUSIONS: ERAS has not yet been widely implemented in urology and evidence for individual interventions is limited or unavailable. The experience in other surgical disciplines encourages the development of an ERAS protocol for cystectomy.

  • 3-methylcrotonyl-CoA carboxylase deficiency and severe multiple sclerosis.
  • 2007
  • Ingår i: Pediatric neurology. - : Elsevier BV. - 0887-8994. ; 36:2, s. 132-4
  • Tidskriftsartikel (refereegranskat)abstract
    • This report describes a female with isolated 3-methylcrotonyl-CoA carboxylase deficiency. She had a mild Reye-like episode, loss of scalp hair, psychomotor retardation, and an attention-deficit hyperactivity disorder. The diagnosis was made at 13 years of age when she developed relapsing remitting multiple sclerosis with a malignant course. Treatment with steroids had initially a good therapeutic effect on the relapses. The response to interferon beta-1a treatment was poor. On mitoxantrone treatment there was a considerable neurologic recovery.

  • Computed tomography and single-photon emission computed tomography as diagnostic tools in acquired brain injury among children and adolescents.
  • 1997
  • Ingår i: Developmental medicine and child neurology. - 0012-1622. ; 39:8, s. 502-7
  • Tidskriftsartikel (refereegranskat)abstract
    • Twenty children with acquired brain injuries were investigated with CT and SPECT. The findings were related to the clinical outcome judged at discharge following acute care after the injury and at follow-up 5 years later. The abnormalities that were found were classified for each lobe on a scale ranging from 0 (normal) to 5 (severe abnormality). The patients were divided into two groups showing mild and severe injury. CT and SPECT revealed similar results in the patients with severe injury, but in the group of mildly injured children the number of affected lobes and scores indicated by SPECT were significantly higher than those indicated by CT. SPECT also differentiated more effectively between the two outcome groups. This supports the hypothesis that SPECT could be used as an instrument to objectivise minor sequelae and that SPECT and CT are both useful methods for forecasting outcome.

  • Investigation of Polymer-Shelled Microbubble Motions in Acoustophoresis
  • Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
    • The objective of this paper is to explore the trajectory motion of microsize (typically smaller than a redblood cell) encapsulated polymer-shelled gas bubbles propelled by radiation force in an acousticstanding-wave field and to compare the corresponding movements of solid polymer microbeads. Theexperimental setup consists of a microfluidic chip coupled to a piezoelectric crystal (PZT) with aresonance frequency of about 2.8 MHz. The microfluidic channel consists of a rectangular chamberwith a width, w, corresponding to one wavelength of the ultrasound standing wave. It creates one fullwave ultrasound of a standing-wave pattern with two pressure nodes at4w and43w and threeantinodes at 0,2w , and w. The peak-to-peak amplitude of the electrical potential over the PZT wasvaried between 1 and 10 volts. From Gor’kov’s potential equation, the acoustic contrast factor, Φ, forthe polymer-shelled microbubbles was calculated to about -60.7. Experimental results demonstratethat the polymer-shelled microbubbles are translated and accumulated at the pressure antinode planes.This trajectory motion of polymer-shelled microbubbles toward the pressure antinode plane is similarto what has been described for other acoustic contrast particles with a negative Φ. First, primaryradiation forces dragged the polymer-shelled microbubbles into proximity with each other at thepressure antinode planes. Then, secondary radiation forces caused them to aggregate at different spotsalong the channel. The relocation time for polymer-shelled microbubbles was 40 times shorter thanthat for polymer microbeads, and in contrast to polymer microbeads, the polymer-shelledmicrobubbles were actuated even at driving voltages (proportional to radiation forces) as low as 1 volt.In short, the polymer-shelled microbubbles demonstrate the behavior attributed to the negativeacoustic contrast factor particles and thus can be trapped at the antinode plane and thereby seperatedfrom solid particles, such as cells. This phenomenon could be utilized in exploring future applications,such as bioassay, bioaffinity, and cell interaction studies in vitro in a well-controlled environment.

  • Clinical characteristics of children with cerebral white matter abnormalities.
  • 2000
  • Ingår i: European journal of paediatric neurology : EJPN : official journal of the European Paediatric Neurology Society. - : Elsevier BV. - 1090-3798. ; 4:1, s. 17-26
  • Tidskriftsartikel (refereegranskat)abstract
    • The rapidly expanding use of magnetic resonance imaging (MRI) in children with neurological impairments of unknown aetiology has revealed a large number of children with abnormalities of the cerebral white matter, some with leukodystrophy-like white matter abnormalities on MRI, but non-progressive in clinical presentation and course. The aim of this study was to investigate the clinical and neuroradiological characteristics of 26 children with white matter abnormalities of unknown origin and to find diagnostic clues or indicators of progressive versus nonprogressive disease. The typical child with white matter abnormalities was characterized by onset of symptoms within the first year of life, most often presenting as general developmental delay and hypotonia. Later-appearing signs were spasticity and ataxia and as a rule severe learning and motor disabilities. Serious ophthalmological signs were frequently seen. Perinatal adverse events were rare, infectious aetiologies not indicated but prenatal stigmata relatively common. The clinical course was progressive in 11 children and non-progressive in 15. Late onset presentation was associated with a progressive course whereas prenatal stigmata and asymmetrical white matter lesions only were found in children with a non-progressive disorder. The MRI showed three main patterns: a) a generalized increase of the T2 signal of the white matter in 12 children, b) a bilateral, symmetric but not generalized abnormality in nine and c) asymmetric, focal or multifocal pathology in five. Useful information as to clinical entities and course was obtained from the combined clinical and radiological assessment. A precise nosological diagnosis could be made in six cases. The study showed that white matter abnormalities in children constitute a heterogeneous group of rare and 'anonymous' conditions, motivating collaborative studies for further clarification of background and management.

  • Disorders of the cerebral white matter in children. The spectrum of lesions.
  • 1996
  • Ingår i: Neuropediatrics. - : Georg Thieme Verlag KG. - 0174-304X .- 1439-1899. ; 27:6, s. 295-8

    • The use of magnetic resonance imaging (MRI) has resulted in the detection of an increasing number of children with an apparently leukodystrophic white matter. Laboratory tests and the clinical presentation, however, often do not correspond to any known entity and the course is sometimes not progressively deteriorating. Such children with white-matter changes and no known diagnosis were the subject of this Swedish multicentre study, in which MRI findings and clinical data from 100 children considered to have white-matter abnormalities were assessed during the period 1992-1995. At re-evaluation of MR images by an established "white-matter group" of neuroradiologists, paediatric neurologists, neurologists and neurochemists, the MRI signal of the white matter was considered normal in eleven children and eleven had mainly a grey matter affection. Of the remaining 78 children with white matter abnormalities, a diagnosis was found in 32, but in 46 children no diagnosis could be established. A progressive downhill course characterised 17, probably representing hitherto undefined types of leukodystrophies. Five children had a relapsing-remitting course, and in 11 it was difficult to establish whether the course was progressive or stationary. The disease was non-progressive in 13. This group of non-leukodystrophic white-matter changes obviously represents maldevelopments of myelin formation, thus dys- or hypomyelination rather than demyelination.

  • A method to analyse observer disagreement in visual grading studies: example of assessed image quality in paediatric cerebral multidetector CT images.
  • 2010
  • Ingår i: The British journal of radiology. - : British Institute of Radiology. - 1748-880X .- 0007-1285. ; 83:991, s. 604-11
  • Tidskriftsartikel (refereegranskat)abstract
    • The purpose was to demonstrate a non-parametric statistical method that can identify and explain the components of observer disagreement in terms of systematic disagreement as well as additional individual variability, in visual grading studies. As an example, the method was applied to a study where the effect of reduced tube current on diagnostic image quality in paediatric cerebral multidetector CT (MDCT) images was investigated. Quantum noise, representing dose reductions equivalent to steps of 20 mA, was artificially added to the raw data of 25 retrospectively selected paediatric cerebral MDCT examinations. Three radiologists, blindly and randomly, assessed the resulting images from two different levels of the brain with regard to the reproduction of high- and low-contrast structures and overall image quality. Images from three patients were assessed twice for the analysis of intra-observer disagreement. The intra-observer disagreement in test-retest assessments could mainly be explained by a systematic change towards lower image quality the second time the image was reviewed. The inter-observer comparisons showed that the paediatric radiologist was more critical of the overall image quality, while the neuroradiologists were more critical of the reproduction of the basal ganglia. Differences between the radiologists regarding the extent to which they used the whole classification scale were also found. The statistical method used was able to identify and separately measure a presence of bias apart from additional individual variability within and between the radiologists which is, at the time of writing, not attainable by any other statistical approach suitable for paired, ordinal data.

  • Evaluation Of Image-Enhanced Paediatric Computed Tomography Brain Examinations
  • 2010
  • Ingår i: Radiation protection dosimetry. - : Oxford University Press (OUP). - 1742-3406 .- 0144-8420. ; 139:1-3, s. 287-292
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to evaluate the possibility of reducing the radiation dose to paediatric patients undergoing computed tomography (CT) brain examination by using image-enhancing software. Artificial noise was added to the raw data collected from 20 patients aged between 1 and 10 y to simulate tube current reductions of 20, 40 and 60 mA. All images were created in duplicate; one set of images remained unprocessed whereas the other was processed with image-enhancing software. Three paediatric radiologists assessed the image quality based on their ability to visualise the high- and low-contrast structures and their overall impression of the diagnostic value of the image. For patients aged 6-10 y, it was found that dose reductions from 27 mGy (CTDI(vol)) to 23 mGy (15 %) in the upper brain and from 32 to 28 mGy (13 %) in the lower brain were possible for standard diagnostic CT examinations when using the image-enhancing filter. For patients 1-5 y, the results for standard diagnostics in the upper brain were inconclusive, for the lower brain no dose reductions were found possible.

  • Tidskriftsartikel (refereegranskat)abstract
    • We retrospectively studied the brain MRIs of 66 pediatric patients with mitochondrial disorder with central nervous system involvement. Forty-one patients had an identified genetic etiology. A predominance of cerebrocortical lesions was mainly seen in patients with MELAS and Alpers syndrome. Basal ganglia were predominantly affected in patients with Leigh syndrome. All patients with leukoencephalopathy had pathological spectroscopy. Cerebrocortical atrophy with agenesis/atrophy of the corpus callosum was seen in patients with congenital lactic acidosis with or without pyruvate dehydrogenase complex deficiency. The diagnostic approach used in our study - from the neuroanatomical/neurofunctional lesion to disease identification - assists the physician in the use of brain neuroimaging early in the diagnostic work-up of suspected mitochondrial disorders.

  • A family with pyruvate dehydrogenase complex deficiency due to a novel C>T substitution at nucleotide position 407 in exon 4 of the X-linked Epsilon1alpha gene.
  • 2005
  • Ingår i: European journal of pediatrics. - : Springer Science and Business Media LLC. - 0340-6199 .- 1432-1076. ; 164:2, s. 99-103
  • Tidskriftsartikel (refereegranskat)abstract
    • The pyruvate dehydrogenase complex (PDHc; McKusick 312170), localised in the mitochondrial matrix, is a multienzyme complex which converts pyruvate to acetyl-CoA. A deficiency of PDHc leads to inadequate removal of pyruvate and lactate resulting in lactic acidaemia and insufficient energy production. The major cause of PDHc deficiency is a defect in the E1alpha component. The gene of this component is localised to Xp22.1. We describe two brothers with a relatively mild clinical phenotype of PDHc deficiency. Onset of disease was associated with muscle weakness and swallowing difficulties in both. At follow-up, the older brother developed encephalopathic features consistent with Leigh syndrome. Lactate to pyruvate ratios were low, consistent with a PDHc deficiency which was confirmed by measurements of PDHc activity in thrombocytes. A 407C>T change in exon 4 of the E1alpha gene was found in both brothers and their mother. This substitution predicts a replacement of a conserved alanine at position 136 by valine. CONCLUSION: Due to the X-linked inheritance pattern combined with the overall results of clinical investigations, molecular genetic findings and a corresponding functional deficiency of the gene product we believe that this substitution in the pyruvate dehydrogenase E1alpha gene is a mutation leading to pyruvate dehydrogenase complex deficiency in this family.

  • Computed tomography as an adjunct in etiological analysis of hemiplegic cerebral palsy. I: Children born preterm.
  • 1991
  • Ingår i: Neuropediatrics. - 0174-304X. ; 22:1, s. 50-6
  • Tidskriftsartikel (refereegranskat)abstract
    • Computed tomography (CT) of the brain has been used to evaluate potential etiologies of hemiplegic cerebral palsy in a population-based group of 28 children born preterm, in whom an obvious postnatal cause of hemiplegia could be excluded. The CT findings were classified according to a system so constructed to reflect the phase of brain maturation during which the insult causing hemiplegia likely had occurred. We found that 50% had evidence of periventricular leukomalacia the lesion typical of hypoxic-ischemic injury to the immature brain. However, it was not possible, neither from the CT scans nor from retrospective review of available clinical data, to date the injury more precisely to the pre- or perinatal period. Analysis of CT findings further showed that 18% of the children had cerebral maldevelopment, indicating an injury during early fetal life as the cause of hemiplegia, earlier than clinically suspected. The CT scans were normal in 25% of the children. It is concluded that the objective information obtained by studying the morphology of brain lesions using CT provides important information in addition to clinical data, and should be integrated with clinical assessment when attempts are being made to evaluate the etiology of cerebral palsy in children.

  • Computed tomography as an adjunct in etiological analysis of hemiplegic cerebral palsy; II: Children born at term.
  • 1991
  • Ingår i: Neuropediatrics. - 0174-304X. ; 22:3, s. 121-8
  • Tidskriftsartikel (refereegranskat)abstract
    • CT brain scans were used to evaluate the most likely etiology of hemiplegic cerebral palsy in a group of children born at term. The population based study group comprised 83 children. The CT findings were classified to reflect the phase of brain maturation during which the injury causing hemiplegia most likely had occurred. The most common finding (37%) was periventricular atrophy considered to represent periventricular leukomalacia (PVL). PVL is a form of hypoxic-ischemic damage typical of the immature brain and most commonly seen as a complication of preterm birth. As this lesion was found in children born at term it was considered to reflect a cerebral injury that had occurred in utero. Cerebral maldevelopment, due to a very early intrauterine lesion, was detected in 17%, while cortical-/subcortical lesions, previously considered to be of major importance in hemiplegia, were seen in just 16% of the children. Altogether the CT findings indicated a prenatal origin of hemiplegia in 57%. Assessing the time of injury based on clinical records concurred with prenatal origin in 32% of the children thought to have prenatal origin of hemiplegia by CT. The objective information available from careful review of imaging information such as CT brain scans, is an important adjunct to clinical data. We propose that assessment of brain morphology, by means of imaging, should be integrated with clinical assessment when evaluating the etiology of brain lesions in children with congenital motor impairment.

  • 1991
  • Ingår i: Developmental medicine and child neurology. - 0012-1622. ; 33:6, s. 512-23
  • Tidskriftsartikel (refereegranskat)abstract
    • Morphological findings on CT were compared with clinical features of 111 children with hemiplegic cerebral palsy. Periventricular atrophy, interpreted as periventricular leukomalacia, was the most prevalent CT finding, although this type of lesion did not indicate severity of neurological impairment. Maldevelopments were associated with arm-dominated hemiplegia and with a wider range of clinical impairments than previously described. Cortical/subcortical atrophy, less common than presumed, indicated arm-dominated hemiplegia and was associated with more severe impairment than were other CT findings. A normal CT scan indicated leg-dominated hemiplegia and mild impairment. The morphological information obtained by CT was found to be useful for predicting clinical outcome, and was considered an important adjunct to clinical history and findings in these children.

  • Tidskriftsartikel (refereegranskat)abstract
    • This study has analysed the results of CT scans of the brains in children with congenital hemiplegia. The material consists of 111 out of a total of 151 children with this cerebral palsy syndrome in a population-based series. We have classified the morphological findings in five groups. The groups are designed to reflect the phase of maturation of the brain when the insult happened. The groups are: 1. Maldevelopment, 2. Periventricular atrophy, 3. Cortical-/subcortical atrophy, 4. Miscellaneous, 5. Normal. In contrast to previous reports we found a high proportion (17%) with maldevelopment. However the dominating morphological pattern was periventricular atrophy, consistent with a hypoxic-ischemic insult to the immature brain, seen in 42%. Cortical and/or subcortical atrophy was found in 12%. Three children (3%) presented with morphological patterns not possible to classify. The group with no pathology according to CT was 26%.
