Traumatic and Non-traumatic Fibromyalgia Syndrome: Impact Assessment on the Life Quality of Women

Objective To investigate the impact on life quality of women with traumatic and non-traumatic origin fibromyalgia syndrome [FMS]. Method Women affected with FMS were selected and divided into two groups: those with traumatic origin FMS [Group 1] and those with non-traumatic origin FMS [Group 2]. A standard question form was used for the research, as well as the fibromyalgia impact questionnaire [FIQ] for evaluation of life quality. Results Seventy-two patients, 34 for Group 1 and 38 for Group 2 were analyzed. The main triggering symptoms were divorce [23.5 percent of cases] and death in the family [23.5 percent of cases]. In addition to diffuse pain, the main symptoms presented were poor sleep quality, weariness, and paresthesia, with no difference between the groups; migraine had a greater prevalence in Group 1 [P = 0.0006]; evaluation of life quality by the FIQ was poorer for Group 1 [P < 0.0001]. Conclusion The impact of FMS on life quality is greater for women suffering from traumatic origin FMS.
Next generation structural health monitoring and its integration into aircraft design

Structural health monitoring (SHM) has become increasingly important with regard to ageing aircraft, required enhanced performance and the need to reduce aircraft operational cost. Affordable advanced miniaturized sensors and continuous improvement in data processing technology combined with powerful software algorithms has allowed non-destructive testing (NDT) to become an integral part of structural materials and has thus given structures a self-sensing functionality. This paper describes where to integrate SHM into the aircraft design process and how to validate the established loads monitoring process in comparison to an emerging damage monitoring solution, before more precisely describing a technology selection regarding damage monitoring. Acousto-ultrasonics is a technique being especially emphasized. Results from laboratory experiments will be shown and commented and a perspective of future trends will be given.
The frequency-domain analysis of discrete variable structure control and chattering-free criteria

Conventionally, the discrete variable structure control always suffers from the chattering phenomenon. Therefore, in this paper, we shall show that, for the discrete variable structure control, there always exist a limit cycle if the traditional nonlinearity of the sign function is used. This limit cycle behaviour is just the chattering phenomenon in the variable structure control theory. In particular, the frequency of this limit cycle is identical to the Nyquist frequency in the sampling theorem. In addition, a theorem related to the chattering-free design for the multiple-input multiple-output variable structure control is proposed. If the nonlinear function is memoryless and belongs to the sector [0,2), the chattering phenomenon can be eliminated. If the width of the boundary layer is enough, the reaching condition as well as chattering-free design can be attained; otherwise, it will result in the chattering phenomenon.
Long‐term trends in the incidence of type 1 diabetes in Denmark: the seasonal variation changes over time

There is a worldwide increase of type 1 diabetes mellitus (T1DM). In 1996, the Danish population‐based registry was initiated including all newly diagnosed children aged 0–15 yr. This is the report of incidence and seasonal variation for the first 10 yr of the registry. The data was analyzed using Poisson’s regression analysis. A total of 2166 children with diabetes were diagnosed before the age of 15 yr between 1996 and 2005. In this period, the annual increase in childhood T1DM was 3.43% (95% confidence interval: 1.91–4.97), which was unaffected by age and gender. Seasonal variation in incidence rates varied by year but not by age and gender. In conclusion, there is a steep increase in incidence of childhood T1DM in Denmark; the increase is comparable with the increase seen in other European countries. There is a significant seasonal variation that changes on a year‐to‐year basis. The observed variations in cadence rates may be associated with viral epidemics, sunshine exposure, or vitamin D levels and suggest further exploration of these relations.
Differential antiinflammatory and antinociceptive effects of the somatostatin analogs octreotide and pasireotide in a mouse model of immune-mediated arthritis.

OBJECTIVE Clinical and preclinical evidence suggests that somatostatin exhibits potent antiinflammatory and antinociceptive properties. However, it is not known which of the 5 somatostatin receptor subtypes (SSTRs 1-5) is involved in these actions. The purpose of this study was to assess the effects of the stable somatostatin analogs octreotide and pasireotide (SOM230) in a mouse model of antigen-induced arthritis (AIA). METHODS Studies were performed in SSTR2-deficient mice (SSTR2(-/-)) and their wild-type littermates (SSTR2(+/+)). The expression of SSTR1, SSTR2A, SSTR3, and SSTR5 in dorsal root ganglia was examined by immunohistochemistry. RESULTS Untreated SSTR2(-/-) mice with AIA displayed joint swelling and mechanical hyperalgesia similar to that seen in SSTR2(+/+) mice. In wild-type mice, both octreotide and pasireotide significantly attenuated knee joint swelling and histopathologic manifestations of arthritis to an extent comparable to that of dexamethasone. In SSTR2(-/-) mice, the antiinflammatory effects of both octreotide and pasireotide were completely abrogated. Prolonged administration of pasireotide also inhibited joint swelling and protected against joint destruction during AIA flare reactions. In addition, both octreotide and pasireotide reduced inflammatory hyperalgesia. The antinociceptive actions of octreotide were abolished in SSTR2(-/-) mice, but those of pasireotide were retained. In dorsal root ganglia of naive wild-type mice, only SSTR1 and SSTR2A, but not SSTR3 or SSTR5, were detected in a subset of small- and medium-diameter neurons. CONCLUSION Our findings indicate that the antinociceptive and antiinflammatory actions of octreotide and pasireotide are largely mediated via the SSTR2 receptor. In addition, we identified the SSTR1 receptor as a novel pharmacologic target for somatostatin-mediated peripheral analgesia in inflammatory pain.
Health Service Use Predictors Among Trauma Survivors: A Critical Review

Summary of Service Use DeterminantsAmong Trauma Survivors and PTSDPatients Although numerous instances of inconclusiveÞndings exist, several general conclusions canbe drawn across studies (with at least a ratio of3:1 studies supporting a given conclusion and atleast three studies examining the given vari-able). Increased MH service use was found forwomen, people with previous or lifetime traumahistories, and people with a PTSD diagnosis.Increased medical service use was found forpeople with a PTSD diagnosis.However,theseconclusionsareinsuencedbythe fact that some studies may not possess ad-equate statistical power to reveal signiÞcant ef-fects. Therefore, we reassessed our general con-clusions after removing from consideration theseven small-sample ( N 100) studies. As aresult, the only modiÞcation to our conclusions(across studies) would be the addition of PTSDseverity as a variable associated with increasedMH service use. Caveat One particular limitation of this reviewshould be emphasized. We included studies thatsampled very different types of trauma survi-vors, an approach we acknowledge as particu-larly inclusive. Traumatic experiences reportedby war soldiers, for example (being both vic-tims and trained agents of insicting trauma), arevery different from those experienced by disas-ter survivors (being unexpected victims of nat-ural or man-made disasters). Additionally, theresulting psychopathology from different typesof traumatic events can vary widely; for exam-ple, combat exposure and sexual assault areassociated with much higher PTSD rates than isdisaster (Kessler et al., 1995). Additionally, the services available to differ-enttypesoftraumasurvivorscanvary.Veteransof war trauma can qualify for services withinthe VA Medical Center, a relatively closedhealth care system, which is inexpensive to vet-erans but can yield relatively long wait times.Conversely, civilian trauma survivors must seekservices in the community, perhaps throughtheir health insurance plans (and in the case ofcriminal victimization, they may have access tocrime victim compensation).
GATA-3 up-regulation in CD8+ T cells as a biomarker of immune dysfunction in systemic sclerosis, resulting in excessive interleukin-13 production.

OBJECTIVE Despite the importance of interleukin-13 (IL-13) in systemic sclerosis (SSc) and other fibrotic diseases, its mechanisms of action are not understood. We have reported that excessive amounts of IL-13 are produced by peripheral blood effector CD8+ T cells from patients with diffuse cutaneous SSc (dcSSc). The aim of the present study was to establish the molecular basis of IL-13 dysregulation in the pathogenesis of SSc. METHODS Quantitative polymerase chain reaction analysis and intracellular staining were used to study the transcription factors that control naive peripheral blood CD8+ T cell differentiation into type 1 and type 2 cytokine-secreting cells. Intracellular staining revealed that GATA-3 levels in freshly isolated naive CD8+ T cells correlated with specific clinical manifestations. We therefore assessed the effects of GATA-3 inhibition on IL-13 production in CD8+ T cells from the SSc patients. RESULTS Freshly isolated naive peripheral blood CD8+ T cells expressed high levels of GATA-3 and failed to down-regulate IL-13 production when cultured under type 1-skewing conditions, but maintained adequate levels of interferon-γ production. Cellular GATA-3 levels were significantly higher in patients with dcSSc and early inflammatory disease. Silencing of GATA-3 with small interfering RNA significantly reduced IL-13 production by CD8+ T cells, demonstrating a causal relationship between GATA-3 and IL-13. CONCLUSION These results provide important new insights into SSc pathogenesis and suggest that increased GATA-3 expression in CD8+ T cells could be a highly relevant biomarker of immune dysfunction in patients with dcSSc. GATA-3 could be a novel therapeutic target for this currently incurable disease.
Pharmacy educators’ intention for the curriculum: an Australian pilot study

Background: Pharmacy educators play an important role in supporting the professional identity formation of students, particularly in relation to their perceptions and strategies for the curriculum and subsequent learning experiences. Aim: To explore pharmacy educators’ perceptions of the purpose of the pharmacy curriculum and how they contribute to students’ development as pharmacists. Methods: A one-off survey using a 20-item questionnaire distributed to all pharmacy educators at a single school of pharmacy who contributed to an Australian undergraduate pharmacy degree program. Results: Most educators viewed the curriculum and their role from a traditional perspective. The educators felt the key purpose of the curriculum was to develop competent pharmacists by providing students with knowledge and skills. There was a limited emphasis on patient-centredness. Conclusion: Whilst educators were focused on developing competent pharmacists through the provision of knowledge and skills, important learning opportunities supporting identity formation may be missed.
Giant cavernoma of the skull and skeletal-extraskeletal angiomatosis associated with paraproteinemia

Skeletal-extraskeletal angiomatosis is defined as a benign vascular proliferation affecting the medullar cavity of the bone and at least one other type of tissue, including skin, subcutaneous tissue, viscera, muscle, or synovium, and which does not spread to avascular tissue such as cartilage. Primary hemangiomas/cavernous hemangiomas (cavernomas) are exceedingly rare in the skull, accounting for 0.2% of all osseous neoplasms and are usually located in frontal and parietal bones. The authors present the case of a 66-year-old man who was admitted with right-side hemiparesis. MRI revealed a destructive bone lesion of the left frontal bone. Digital subtraction angiography of the brain did not reveal pathological vascularization, but a minor submucous hemangioma was seen in the nasal airway. Urine test for Bence-Jones proteins was positive for IgG λ light chain. Bone marrow aspiration and CSF analysis revealed no evidence of systemic myelomatosis suggesting a monoclonal gammopathy of undetermined significance. A highly vascular tumor was surgically removed. The histopathology verified cavernous hemangioma of the skull and the nasal submucous hemangioma. We discuss the diagnostic procedure, possible pathophysiological mechanisms and treatment implementation. It is possible that immunoglobulins from monoclonal gammopathies have an etiologic role in the development of the bone and skin changes in older patients, as an acquired condition, by producing a vascular injury that could lead to the multiple hemangiomas in skeletal-extraskeletal angiomatosis. To prevent misdiagnosis with lesions of other origins, multiple lesions of the head must be resected and histopathologically verified. In conclusion, to the best of our knowledge, this is the first case of giant cavernous hemangioma of the skull associated with paraproteinemia and skeletalextraskeletal angiomatosis limited to the head.
Severity of mood symptoms and work productivity in people treated for bipolar disorder.

OBJECTIVE To evaluate the relationship between mood symptoms and work productivity in people with bipolar disorder. METHODS A total of 441 outpatients treated for bipolar disorder were enrolled from mental health clinics of a health plan in Washington State. A baseline assessment included confirmation of diagnosis (using the Structured Clinical Interview for DSM-IV) as well as assessment of employment status, functional impairment, and days missed from work. Eight follow-up interviews over 24 months included self-reported employment status, self-reported days missed from work due to illness, and assessment of current and interval mood symptoms using the Longitudinal Interval Follow-up Examination. RESULTS Averaged over four assessments, patients with current major depression were 15% less likely to be employed than those without significant depressive symptoms [odds ratio (OR) = 0.84, 95% confidence interval (CI): 0.76-0.92]. Manic or hypomanic symptoms were not significantly associated with probability of employment (OR = 0.93, CI: 0.83-1.04). Among those employed, major depression was associated with 4.06 additional days of work missed per month (CI: 1.05-7.06) compared to those without significant depressive symptoms. Meeting criteria for manic or hypomanic episode was associated with a similar number of missed work days, but this difference was not statistically significant (adjusted difference = 4.11 days, CI: -0.18-8.40). CONCLUSIONS Among patients with bipolar disorder, depression is strongly and consistently associated with decreased probability of employment and more days missed from work due to illness. Symptoms of mania or hypomania have more variable effects on work productivity.
HLA associations reveal genetic heterogeneity in psoriatic arthritis and in the psoriasis phenotype.

OBJECTIVE Rigorously ascertained cases of psoriatic arthritis in subjects presenting to a rheumatology unit were compared with cases of psoriasis in subjects presenting to a dermatology unit, where subjects with musculoskeletal features were excluded, to address 1) the extent to which the contribution of the major histocompatibility complex (MHC) to psoriatic arthritis susceptibility resembles that in psoriasis, and 2) whether MHC genes determine quantitative traits within the psoriatic arthritis phenotype. METHODS Separate discovery and validation subcohorts of patients recruited from a relatively homogeneous population were studied by sequence-based HLA typing, in which frequencies of the HLA-B and HLA-C alleles and haplotypes were compared. RESULTS In patients with psoriatic arthritis, the frequency of C*06:02 was lower than that in patients with psoriasis (28.7% versus 57.5%; P = 9.9 × 10(-12) ). Three haplotypes containing B*27:05 or B*39:01 were significantly increased in frequency in patients with psoriatic arthritis, but not in those with psoriasis. The structurally related B*39:06 allele was not increased in frequency. B*27 was associated with an interval of 0.98 years between skin and musculoskeletal disease (P = 2.05 × 10(-6) ), compared with an interval of 10.14 years for C*06. Preliminary evidence suggested that B*38:01 and B*08 may be associated with psoriatic arthritis susceptibility, and that allotypes encoding P2 pockets that bind side chains opposite in charge from those encoded by the B*27 and B*39 molecules may exert a protective role. CONCLUSION These findings suggest that the psoriasis phenotype results from two patterns of MHC effect. The first involves the classic psoriasis susceptibility gene C*06, which confers more penetrant skin disease with less prevalent and more time-dependent musculoskeletal phenotype development. The second pattern appears to be mediated by HLA-B alleles, notably B*27, and includes temporally more coincident musculoskeletal involvement that is nearly equivalent in penetrance to that of the skin disease.
Association study in a Sardinian sample between bipolar disorder and the nuclear receptor REV-ERBalpha gene, a critical component of the circadian clock system.

OBJECTIVE The aim of our study was to investigate the association between REV-ERBalpha gene (NR1D1) single nucleotide polymorphisms (SNPs) and bipolar disorder (BP) in a case-control sample of Sardinian ancestry and evaluate its effect on age at onset (AAO) of BP. METHODS We genotyped SNPs rs12941497 (SNP1) and rs939347 (SNP2), located, respectively, in the first intron and in the 5'UTR region of the gene, in a sample comprised of 300 bipolar patients and 300 healthy controls of Sardinian ancestry. We also studied AAO by means of admixture analysis, obtaining a cutoff point of age 22 and then carrying out association analysis between the two AAO groups. RESULTS In the case-control comparison, single marker analysis showed no association for any of the SNPs tested. Haplotype analysis showed a nominally significant association for two haplotypes of SNPs 1-2. Comparing the early- and later-onset groups, nominal association was found for SNP1. Haplotype analysis showed that one haplotype was nominally associated with the later-onset group. CONCLUSIONS Our results, indicating a nominal association of the REV-ERBalpha gene with BP, suggest a possible role of REV-ERBalpha in the pathogenesis of BP. Further investigation of larger independent samples and different populations is warranted.
Interleukin-22 and interleukin-22-producing NKp44+ natural killer cells in subclinical gut inflammation in ankylosing spondylitis.

OBJECTIVE The intestinal inflammation observed in patients with ankylosing spondylitis (AS) is characterized by an overexpression of interleukin-23 (IL-23). IL-23 is known to regulate IL-22 production through lamina propria NKp44+ natural killer (NK) cells, which are thought to be involved in protective mucosal mechanisms. This study was undertaken to evaluate the frequency of NKp44+ NK cells and the expression of IL-22 in the ileum of AS patients. METHODS Tissue NKp44+ NK cells, NKp46+ NK cells, and IL-22-producing cells were analyzed by flow cytometry. Quantitative gene expression analysis of IL-22, IL-23, IL-17, STAT-3, and mucin 1 (MUC-1) was performed by reverse transcriptase-polymerase chain reaction on ileal samples from 15 patients with AS, 15 patients with Crohn's disease (CD), and 15 healthy controls. NKp44, pSTAT-3, and IL-22 expression was analyzed by immunohistochemistry. RESULTS The frequency of NKp44+ but not NKp46+ NK cells was increased in the inflamed ileum of AS patients compared to CD patients and controls. The frequency of NKp46+ NK cells was significantly increased only in CD patients. Among CD4+ lymphocytes and NKp44+ NK cell subsets, the latter were the major source of IL-22 on lamina propria mononuclear cells from AS patients. Significant up-regulation of IL-22, IL-23p19, MUC-1, and STAT-3 transcripts in the terminal ileum of patients with AS was observed. Immunohistochemical analysis confirmed the increased IL-22 and pSTAT-3 expression in inflamed mucosa from AS and CD patients. CONCLUSION Our findings indicate that overexpression of IL-22, together with an increased number of IL-22-producing NKp44+ NK cells, occurs in the gut of AS patients, where it appears to play a tissue-protective role.
Lysophosphatidic acid receptor 1 suppression sensitizes rheumatoid fibroblast-like synoviocytes to tumor necrosis factor-induced apoptosis.

OBJECTIVE To investigate the role of lysophosphatidic acid (LPA) receptors in the proliferation and apoptosis of fibroblast-like synoviocytes (FLS) from patients with rheumatoid arthritis (RA). METHODS Expression of LPA receptors 1-3 was analyzed by real-time polymerase chain reaction (PCR). LPAR1 and LPAR2 were suppressed in RA FLS by small interfering RNA (siRNA) transfection. Proliferation of RA FLS after tumor necrosis factor (TNF) and LPA stimulation was determined with a luminescent cell viability assay. Apoptosis was analyzed by quantification of nucleosome release and measurement of activated caspase 3/7. Genes involved in the apoptotic response were identified with a human apoptosis PCR array and validated with Western blot assays. The requirement of these genes for apoptosis sensitization was assessed by siRNA transfection. Secretion of mediators of inflammation was analyzed by enzyme-linked immunosorbent assay. RESULTS Only LPAR1 and LPAR2 were expressed by RA FLS, and their levels were higher than those in osteoarthritis (OA) FLS. Suppression of LPAR1 abrogated TNF-induced proliferation and sensitized the RA FLS, but not the OA FLS, to TNF-induced apoptosis. These changes occurred despite an increased early inflammatory response to TNF. Sensitization to apoptosis was associated with changes in expression of multiple apoptosis-related genes. Three of the up-regulated proapoptotic genes were further studied to confirm their involvement. In contrast, suppression of LPAR2 showed no effect in any of these analyses. CONCLUSION LPA(1) is an important receptor in RA FLS. Its suppression is accompanied by a global increase in the response to TNF that is ultimately dominated by sensitization to apoptosis.
