Objective: To investigate the presence of small nerve fiber dysfunction in subjects with X-linked adrenoleukodystrophy. Methods: Cross-sectional study in which 11 Norwegian subjects (3 males, 8 females) with X-linked adrenoleukodystrophy, phenotypes ranging from asymptomatic to wheelchair-bound with adrenomyeloneuropathy, were investigated with neurophysiologic studies including EMG, nerve conduction velocities, quantitative sensory testing, tests of autonomic function, and skin biopsy for intraepidermal nerve fiber density measurements. Results: We found small nerve fiber dysfunction in 10 of 11 subjects, increasing with age and more pronounced in males. Low intraepidermal nerve fiber densities were found in 5 of 11 subjects, indicating a loss of thin unmyelinated nerve fibers peripherally. Five of 11 subjects showed small nerve fiber dysfunction despite normal nerve fiber densities, suggesting possible involvement of the spinothalamic tracts. Two subjects showed moderate abnormalities in autonomic function tests. Conclusions: Evidence of small nerve fiber dysfunction was widespread in this cohort of subjects with X-linked adrenoleukodystrophy, with findings indicating loss of peripheral small nerve fibers and possibly also fibers of the spinothalamic tracts. The results support the theory of primary axonal degeneration in adrenomyeloneuropathy. Evidence of nervous system involvement was found in all heterozygotes, with severity increasing with age. Clinicians caring for these patients should be alert to signs of small nerve fiber involvement. © 2014 American Academy of Neurology.

Background and purpose A successful outcome after lumbar discectomy indicates a substantial improvement. To use the cutoffs for minimal clinically important difference (MCID) as success criteria has a large potential bias, simply because it is difficult to classify patients who report that they are "moderately improved". We propose that the criteria for success should be defined by those who report that they are "completely recovered" or "much better". Methods A cohort of 692 patients were operated for lumbar disc herniation and followed for one year in the Norwegian Registry for Spine Surgery. The global perceived scale of change was used as an external criterion, and success was defined as those who reported that they were "completely recovered" or "much better". Criteria for success for each of (1) the Oswestry disability index (ODI; score range 0-100 where 0 = no disability), (2) the numerical pain scale (NRS; range 0-10 where 0 = no pain) for back and leg pain, and (3) the Euroqol (EQ-5D; -0.6 to 1 where 1 = perfect health) were estimated by defining the optimal cutoff point on receiver operating characteristic curves. Results The cutoff values for success for the mean change scores were 20 (ODI), 2.5 (NRS back), 3.5 (NRS leg), and 0.30 (EQ-5D). According to the cutoff estimates, the proportions of successful outcomes were 66% for the ODI and 67% for the NRS leg pain scale. Interpretation The sensitivity/specificity values for the ODI and leg pain were acceptable, whereas they were very low for the EQ-5D. The cutoffs for success can be used as benchmarks when comparing data from different surgical units.

Background: Tumour necrosis factor inhibitors (TNFi) are efficacious in patients with psoriatic arthritis (PsA), but some patients do not respond or do not tolerate their first TNFi, and are switched to a different TNFi. Evidence supporting this practice is limited, and we wanted to investigate the effectiveness of switching to a second TNFi. Material and methods: From a longitudinal observational study (LOS) we selected patients with PsA who were starting their first TNFi, and identified patients who had switched to a second TNFi ('switchers'). Three-month responses and 3-year drug-survival were compared between switchers and non-switchers, and within switchers. Results: Switchers (n=95) receiving their second TNFi had significantly poorer responses compared with non-switchers (n=344) (ACR50 response: 22.5% vs 40.0%, DAS28 remission: 28.2% vs 54.1%). There was a trend towards poorer responses to the second TNFi compared with the first TNFi within switchers. Estimated 3-year drug-survival was 36% for the second TNFi compared with 57% for the first TNFi overall. Conclusions: 20-40% of patients had a response on a second TNFi after having failed one TNFi in this LOS. This observation highlights the need for treatments with other mechanisms of action than TNF inhibition in patients with PsA.

Background Application of evidence-based perioperative care protocols reduces complication rates, accelerates recovery and shortens hospital stay. Presently, there are no comprehensive guidelines for perioperative care for gastrectomy. Methods An international working group within the Enhanced Recovery After Surgery (ERAS®) Society assembled an evidence-based comprehensive framework for optimal perioperative care for patients undergoing gastrectomy. Data were retrieved from standard databases and personal archives. Evidence and recommendations were classified according to the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system and were discussed until consensus was reached within the group. The quality of evidence was rated 'high', 'moderate', 'low' or 'very low'. Recommendations were graded as 'strong' or 'weak'. Results The available evidence has been summarized and recommendations are given for 25 items, eight of which contain procedure-specific evidence. The quality of evidence varies substantially and further research is needed for many issues to improve the strength of evidence and grade of recommendations. Conclusion The present evidence-based framework provides comprehensive advice on optimal perioperative care for the patient undergoing gastrectomy and facilitates multi-institutional prospective cohort registries and adequately powered randomized trials for further research.

Background: The aim of this study was to investigate the changes and time course of recovery of regional myocardial function within the first week following successful primary coronary intervention in patients with first-time ST-segment elevation myocardial infarctions using myocardial deformation analysis, which is more quantitative and thus more objective than the wall motion score. Methods: Thirty-one consecutive patients admitted with ST-segment elevation myocardial infarctions were studied on days 1, 2, 3, and 7 using strain and strain rate tissue Doppler echocardiography. Results: The mean peak troponin T level was 7.0 μg/L, and 15 patients had anterior and 16 had inferior infarct localization. Peak systolic strain rate and end-systolic strain increased significantly on day 2, both in segments with moderately reduced function (-0.6 to -1.0 s-1 vs -8% to -15%, P < .001) and in severely reduced function (-0.2 to -1.0 s-1 vs 1% to -12%, P < .001), but there were no further changes. Mean wall motion score in infarct related segments decreased significantly from day 1 to day 2 (2.7 to 2.4, P = .001) and from day 3 to day 7 (2.3 to 2.2, P = .001). Conclusions: Recovery of regional function after ST-segment elevation myocardial infarction occurred within 2 days and could be detected by wall motion score, strain rate, and strain. However, strain and strain rate were better discriminative parameters for the changes in function as well as being better to assess near normalization on day 2. This could have a clinical impact on early management in patients who undergo percutaneous coronary intervention. © 2010 American Society of Echocardiography.

Cytokine | Year: 2011
Background: Crohn's disease (CD) and ulcerative colitis (UC) have been associated with a T helper1 (TH1) and a TH2 cytokine profile, respectively. Recently, a TH17 lineage has been introduced, but their role in the inflammation of CD and UC is not fully understood. Aim: To characterize the cytokines directing the TH17 cells and their interactions with TH1 cells in the mucosa of untreated patients with CD and UC. Method: Seventy-nine patients with untreated UC, 32 patients with untreated CD and 23 controls with no signs of colon disease were included in the study. Clinical indices for ulcerative colitis (UCDAI) and Crohn's disease (CDAI) were assessed. Biopsies for measurements of interleukin (IL)-17A, IL-23, IL-6, transforming growth factor-beta (TGF-β), interferon-gamma (IFN-γ), mRNA levels as well as immunohistochemical (IHC) analyses were performed. Results: The gene expression for all cytokines in UC and for all cytokines except for TGF-β in CD were significantly increased compared with the controls. The immunohistochemical analysis showed significantly increased number of IL-17A positive cells in lamina propria and epithelium of both UC and CD compared to controls. The levels of IL-17A and IL-23 mRNA were significantly higher in UC than in CD while the levels of IL-6 were significantly higher in CD compared with UC. The levels of IL-17A, IL-6 and IL-23 mRNA were associated with the disease activity score in both UC and CD. IFN-γ was associated with the disease activity in UC, but did not reach significant level in CD. Conclusion: Increased levels of IL-17A and IL-23 were found in both UC and CD compared to controls. Association to the grade of inflammation and clinical activity was also observed. IL-17A and IL-23 were significantly higher in UC than in CD. TH1 and TH17 cytokines seem to act synergistically in inflammatory bowel disease (IBD) with no apparent polarization between UC and CD. © 2011 Elsevier Ltd.

Clinical Decision Support (CDS) Systems are considered crucial for diagnosis, treatment and care of patients. However, practical benefits of such systems have been far below expectations. This paper explores how the evolving interdependencies in organizational, clinical, political, and behavioral terms influence the design and implementation of CDS. The paper discusses how these interdependencies complicate clinical use of CDS where cross-departmental patient pathways increasingly dominate approaches to dealing with patients with complex conditions. Empirically, we report from an acute geriatric patient pathway project. The aim was to design and implement a decision-support form for triage of elderly patients in the emergency unit. The study emphasizes the intertwined collaborative nature of healthcare work, and the resulting need to consider the whole context when designing and implementing CDS tools. The contribution is to emphasize the "extended design" perspective to capture how workplace technologies and practices are shaped across multiple contexts and prolonged periods. © 2016 ACM.

Dual diagnosis of substance abuse and severe psychiatric illness is frequent, and the building of therapeutic relationships with this group of patients seems to be both important and difficult. An integrated treatment model has been claimed to be the preferred treatment for dual diagnosis patients. This study explores how providers in an integrated treatment model, and a substance abuse treatment model with less emphasis on psychiatric co-morbidity, handle relationship building. Two focus groups included providers working in a Therapeutic Community (TC) and a Dual Diagnosis (DD) ward. Participants were given a short case history and asked to describe how they would approach the case. The analysis was based on a phenomenological method. All providers perceived a good relationship to be central to the treatment. Providers in the DD ward were more ready to build close relationships with the patients, and described their relationship with the patients as more crucial to treatment. The providers in the TC ascribed more importance to the role of peers and to the structure of the program itself. The providers agreed that a good therapeutic relationship is important to treatment. They differed in their opinion about how central this relationship was. © 2010 International Nurses Society on Addictions.

Neuroblastoma is a pediatric tumor of the sympathetic nervous system. Amplification and overexpression of the MYCN proto-oncogene occurs in approximately 20% of neuroblastomas and is associated with advanced stage disease, rapid tumor progression, and poor prognosis. MYCN encodes the transcriptional regulator N-myc, which has been shown to both up- and downregulate many target genes involved in cell cycle, DNA damage, differentiation, and apoptosis in neuroblastoma. During the last years, it has become clear that N-myc also modulates the expression of several classes of noncoding RNAs, in particular microRNAs. MicroRNAs are the most widely studied noncoding RNA molecules in neuroblastoma. They function as negative regulators of gene expression at the posttranscriptional level in diverse cellular processes. Aberrant regulation of miRNA expression has been implicated in the pathogenesis of neuroblastoma. While the N-myc protein is established as an important regulator of several miRNAs involved in neuroblastoma tumorigenesis, tumor suppressor miRNAs have also been documented to repress MYCN expression and inhibit cell proliferation of MYCN-amplified neuroblastoma cells. It is now becoming increasingly evident that N-myc also regulates the expression of long noncoding RNAs such as T-UCRs and ncRAN. This review summarizes the current knowledge about the interplay between N-myc and noncoding RNAs in neuroblastoma and how this contributes to neuroblastoma tumorigenesis. ©2012 AACR.

Background: Like other indigenous peoples, the Sami have been exposed to the huge pressures of colonisation, rapid modernisation and subsequent marginalisation. Previous studies among indigenous peoples show that colonialism, rapid modernisation and marginalisation is accompanied by increased stress, an unhealthy cardiovascular risk factor profile and disease burden. Updated data on the general burden of cardiovascular disease among the Sami is lacking. The primary objective of this study was to assess the relationship between marginalisation and self-reported lifetime cardiovascular disease (CVD) by minority/majority status in the rural Sami population of Norway. Methods. A cross-sectional population-based study (the SAMINOR study) was carried out in 2003-2004. The overall participation rate was 60.9% and a total of 4027 Sami individuals aged 36-79 years were included in the analyses. Data was collected by self-administrated questionnaires and a clinical examination. Results: The logistic regression showed that marginalised Sami living in Norwegian dominated areas were more than twice as likely to report CVD as non-marginalised Sami living in Sami majority areas (OR 2.10, 95% CI: 1.40-3.14). No sex difference was found in the effects of marginalisation on self-reported life-time cardiovascular disease. Moderate to no intermediate effects were seen after including established CVD risk factors. Conclusions: This study showed that marginalised Sami living in Norwegian dominated areas were more than twice as likely as non-marginalised Sami from Sami majority areas to report lifetime cardiovascular disease (CVD). Moderate to no intermediate effects were seen after including established CVD risk factors, which suggest little difference in lifestyle related factors. Chronic stress exposure following marginalisation may however be a plausible explanation for some of the observed excess of CVD. © 2013 Eliassen et al.; licensee BioMed Central Ltd.
