ObjectiveX linked Charcot-Marie-Tooth disease (CMTX) is a hereditary neuropathy caused by mutations in GJB1 coding for connexin-32, a gap junction protein expressed in Schwann cells, but also found in oligodendrocytes. Four patients with CMTX developing central nervous system (CNS) demyelination compatible with multiple sclerosis (MS) have been individually published. We presently sought to systematically investigate the relationship between CMTX and MS.MethodsOver 20 years, 70 consecutive patients (36 men) with GJB1 mutations were identified at our Neurogenetics Unit, Athens, Greece, and assessed for clinical features suggestive of MS. Additionally, 18 patients with CMTX without CNS symptoms and 18 matched controls underwent brain MRI to investigate incidental findings. Serum from patients with CMTX and MS was tested for CNS immunoreactivity.ResultsWe identified three patients with CMTX who developed clinical features suggestive of inflammatory CNS demyelination fulfilling MS diagnostic criteria. The resulting 20-year MS incidence (4.3%) differed significantly from the highest background 20-year MS incidence ever reported from Greece (p=0.00039). The search for incidental brain MRI findings identified two CMTX cases (11%) with lesions suggestive of focal demyelination compared with 0 control. Moreover, 10 cases in the CMTX cohort had hyperintensity in the splenium of the corpus callosum compared with 0 control (p=0.0002). No specific CNS-reactive humoral factors were identified in patients with CMTX and MS.ConclusionsWe have demonstrated a higher than expected frequency of MS in patients with CMTX and identified incidental focal demyelinating lesions on brain MRI in patients with CMTX without CNS symptoms. This provides circumstantial evidence for GJB1 mutations acting as a possible MS risk factor.

ObjectiveTo conduct subset analyses of SPIRIT-P2 (NCT02349295) to investigate the efficacy and safety of ixekizumab versus placebo in three subgroups of patients with active psoriatic arthritis (PsA) according to the concomitant conventional synthetic disease-modifying antirheumatic drug (cDMARD) received: any background cDMARDs (including methotrexate), background methotrexate only, or none.MethodsPatients were randomised to receive placebo, ixekizumab 80 mg every 4 weeks (IXEQ4W) or every 2 weeks (IXEQ2W). Efficacy and safety were assessed when patients were subdivided according to cDMARD use at baseline. Efficacy was evaluated versus placebo at week 24 by the American College of Rheumatology criteria (ACR20/50), achievement of minimal disease activity (MDA) state, Disease Activity Index for PsA (DAPSA), 28-joint Disease Activity Score using C-reactive protein (DAS28-CRP), Health Assessment Questionnaire-Disability Index and the 36-item Short-Form health survey physical functioning domain.ResultsRegardless of background cDMARD status, ACR20, ACR50 and MDA response rates were significantly higher than placebo with IXEQ4W or IXEQ2W treatment. Similarly, significant improvements were observed relative to placebo for DAS28-CRP and DAPSA across subgroups. Physical function also significantly improved relative to placebo with IXEQ4W treatment regardless of background cDMARD status and with IXEQ2W alone. Percentages of reported treatment-emergent adverse events (AEs), serious AEs (including serious infections) and discontinuations due to AEs in each subgroup were comparable to the overall SPIRIT-P2 population.ConclusionIxekizumab was efficacious in patients with active PsA and previous tumour necrosis factor inhibitor (TNFi) inadequate response or TNFi intolerance treated with ixekizumab alone or when added to cDMARDs with subgroup safety profiles that were consistent with that observed in the overall SPIRIT-P2 population.

Objective
To assess the cost-effectiveness of three testing strategies with or without light microscopic Gram-stained smear (GSS) evaluation for the detection of anogenital gonorrhoea among men who have sex with men (MSM) at the Amsterdam STI clinic using a healthcare payer perspective.

Methods
Three testing strategies for MSM were compared: (1) GSS in symptomatic MSM only (currently practised strategy), (2) no GSS and (3) GSS in symptomatic and asymptomatic MSM. The three testing protocols include testing with nucleic acid amplification test to verify the GSS results in (1) and (3), or as the only test in (2). A transmission model was employed to calculate the influence of the testing strategies on the prevalence of anogenital gonorrhoea over 10 years. An economic model combined cost data on medical consultations, tests and treatment and utility data to estimate the number of epididymitis cases and quality-adjusted life years (QALY) associated with gonorrhoea. Incremental cost-effectiveness ratios (ICERs) for the testing scenarios were estimated. Uncertainty and sensitivity analyses were performed.

Results
No GSS testing compared with GSS in symptomatic MSM only (current strategy) resulted in nine extra epididymitis cases (95% uncertainty interval (UI): 2–22), 72 QALYs lost (95% UI: 59–187) and €7300 additional costs (95% UI: −€185 000 (i.e.cost-saving) to €407 000) over 10 years. GSS testing in both symptomatic and asymptomatic MSM compared with GSS in symptomatic MSM only resulted in one prevented epididymitis case (95% UI: 0–2), 1.1 QALY gained (95% UI: 0.1–3.3), €148 000 additional costs (95% UI: €86 000 to–€217 000) and an ICER of €177 000 (95% UI: €67 000–to €705 000) per QALY gained over 10 years. The results were robust in sensitivity analyses.

Conclusions
GSS for symptomatic MSM only is cost-effective compared with no GSS for MSM and with GSS for both symptomatic and asymptomatic MSM.
Emergence of novel phenomena on the border of low dimensional spin and charge order
Authors: Haines Charles R. S. , Saxena Siddharth S. 
Published: September 2018

AbstractProximity to magnetic order as well as low dimensionality are both beneficial to superconductivity at elevated temperatures. Materials on the border of magnetism display a wide range of novel and potentially useful phenomena: highTcs, heavy fermions, coexistence of magnetism and superconductivity and giant magnetoresistance. Low dimensionality is linked to enhanced fluctuations and, in the case of heavy fermions, has been experimentally shown to be beneficial for the fluctuations that are responsible for the rich abundance of novel emergent phases. This experimental strategy motivated us to explore 2D insulating magnets with a view to investigate phase evolution across metal-insulator and magnetic-non-magnetic boundaries. This has been a fruitful venture with totally novel results different to our expectations. We present results from 2 distinct systems. The MPS3family are highly anisotropic in both their crystal and magnetic structures. FePS3in particular is a model insulating honeycomb antiferromagnet. We find that the application of pressure to FePS3induces an insulator to metal transition. The second system, Cs2CuCl4, is a highly-frustrated quantum spin liquid at low temperature. The competition of the 3 relevant exchange couplings is delicately balanced. It has been shown to become antiferromagnetic at very low temperatures (~1 K). We have found that the application of pressure for 3 days or more followed by a return to ambient pressure stabilises a totally distinct magnetic ground state.
The Ladies Vanish?

AbstractMany notable female sociologists have vanished from the canonical history of American sociology. As the most influential crowd-sourced encyclopedia, Wikipedia promises – but does not necessarily deliver – a democratic corrective to the generation of knowledge, including academic knowledge. This article explores multiple mechanisms by which women either enter or disappear from the disciplinary record by analyzing the unfolding interaction between the canonical disciplinary history of sociology and Wikipedia. We argue that the uneven representation of women sociologists as (1) remembered, (2) neglected, (3) erased or, finally, (4) recovered is shaped by the emerging interactional space of knowledge production.

Purpose The purpose of this study is to identify barriers, facilitators, and consequences of obtaining sufficient sleep in adolescents with type 1 diabetes. Methods Semistructured interviews were conducted with 25 adolescents (52% female, mean age = 15.6 years) and 25 caregivers. Interviews were transcribed and coded using Atlas.ti. A thematic analytic approach was used to identify and organize significant patterns of meaning (themes) and interpret themes across the data. Results Several barriers were identified, with the most common being the use of electronics before bed and sleep disturbances related to diabetes management. Caregivers described strategies for helping adolescents achieve sufficient sleep, such as enforcing bedtimes and limiting distractions, but many adolescents could not identify facilitators of sleep. Weekday/weekend discrepancies in sleep timing were commonly disclosed. Conclusions This study is the first to examine the perceptions of barriers and facilitators to obtaining sufficient sleep in adolescents with T1D and their caregivers. Results have the potential to inform providers’ recommendations regarding sleep, including possible interventions to promote sleep in this high-risk population.
Unequal Exchange in the Age of Globalization
Authors: Ricci Andrea 
Published: September 2018

Unequal exchange arises when spatial production of value is disjointed from its geographical distribution. A disaggregated monetary model of the world economy is presented on the grounds of Marx’s labor theory of value. All the forms of unequal exchange in international trade are explained, on the basis of a coherent definition of the forms of international value of traded commodities. Estimates of value transfers for recent years show the ongoing relevance of the unequal exchange in the modern capitalist world economy. JEL classifications: B51, D46, F63
Dynamic mechanical properties and characterization of chemically treated sisal fiber-reinforced polypropylene biocomposites
Authors: Bassyouni M 
Published: September 2018

The incorporation of sisal fiber as reinforcement materials for polymers will be advantageous if it is synthesized and manufactured perfectly. In this study, surface modification using polymeric diphenylmethane di-isocyanate and gamma-aminopropyltriethoxysilane was applied for further amelioration of polypropylene–sisal bonding. Surface morphology, thermomechanical properties, thermal stability, and chemical bonding were investigated using scanning electron microscopy, dynamic mechanical analysis, thermogravimetric analysis, and Fourier transform infrared spectroscopy, respectively. A number of mathematical models were studied for predicting the effect of untreated and modified sisal fiber loadings on the mechanical properties of biocomposites. Polymeric diphenylmethane di-isocyanate showed a significant improvement on the thermal and mechanical properties of polypropylene biocomposites. Fourier transform infrared spectroscopy analysis of polypropylene–sisal biocomposite showed the formation of urethane group at 3333 cm−1 in the presence of polymeric diphenylmethane di-isocyanate. Glass transition temperature of polypropylene–sisal was slightly increased to 6.8°C by chemical modification with polymeric diphenylmethane di-isocyanate. Yield strength of polypropylene–sisal (30 wt%) was enhanced by more than 50% with polymeric diphenylmethane di-isocyanate chemical treatment. Halpin–Tsai and Nielsen theoretical mathematical models showed a good agreement with experimental results of polypropylene–untreated sisal and polypropylene–treated sisal, respectively.

Introduction/Objectives Non- albicans Candida species such as Candida parapsilosis and Candida glabrata have emerged as prevalent pathogens in premature infants. The aim of this study was to systematically delineate the histopathologic findings in neonatal non- albicans candidiasis. Methods We performed a retrospective clinicopathologic analysis of extremely premature (23–28 weeks’ gestation) infants diagnosed with invasive candidiasis. Archival autopsy tissues were subjected to periodic acid-Schiff, methenamine-silver and anti- Candida (immuno)histochemical stains, as well as dual anti- Candida and anti-cytokeratin or anti-CD31 immunofluorescence assays. In addition, we studied the prevalence of intestinal Candida colonization in a consecutive autopsy series of extremely premature infants. Results Based on positive postmortem blood and/or lung cultures, invasive candidiasis (3 non- albicans and 11 Candida albicans) was diagnosed in 14 of the 187 extremely premature infants examined between 1995 and 2017. In contrast to the well-known inflammatory and tissue-destructive phenotype of congenital C. albicans infection, invasive non- albicans candidiasis/candidemia caused by C. parapsilosis and C. glabrata was inconspicuous by routine hematoxylin-eosin-based histopathologic analysis despite a heavy fungal presence detected in intestines, lungs, and blood by targeted (immuno)histochemical assays. Intestinal colonization by Candida species was identified in 16 of the 26 (61%) extremely premature neonates who had lived for at least 1 week, as assessed by anti- Candida immunostaining. Conclusion Invasive neonatal non- albicans candidiasis/candidemia appears to have no distinct histopathologic signature. Based on the notoriously low sensitivity of fungal blood cultures and the observed high frequency of Candida intestinal colonization (>50%), it is likely that non- albicans candidiasis/candidemia may be underdiagnosed in (deceased) preterm infants. Routine inclusion of targeted (immuno)histochemical fungal detection strategies in the perinatal autopsy may lead to deeper insight into the prevalence and clinical relevance of neonatal non- albicans candidiasis.

Published: September 2018

Introduction Technology-based innovation requires long-term changes to workforce routines, otherwise practices will not be sustained. The aim of this study was to identify influential factors in the ongoing use of an acute stroke telemedicine programme. Methods A new acute stroke telemedicine programme in a regional hospital receiving 375 patients with stroke or transient ischaemic attack per year was used as an exploratory case study. Semi-structured interviews with acute care and emergency department clinicians ( n = 25) were conducted at two time-points: after a six-month pilot and then after a further 12-month implementation phase. Interviews (between 12–60 min) were recorded, transcribed and analysed inductively using descriptive thematic analysis. Reported barriers and facilitators were compared with those previously reported pre-implementation (deductive analysis) to identify changes over time. Using an implementation framework and a behaviour change taxonomy, strategies were developed to address influential factors on sustainability. Results New facilitators were identified including hospital system changes, benefits to clinicians and telemedicine becoming standard practice. New and ongoing barriers included infrequent use, competing demands and the continued resistance to a specific treatment. Discussion Understanding the factors supporting a health service in successfully implementing change can accelerate population benefits. The innovation itself may include barriers to be addressed, and barriers and facilitators can change over time. Individual attitudes remain critical to initial and ongoing success. Strategies proposed included promoting benefits across the organisation and allaying uncertainties with site-specific evidence. The effectiveness of these strategies, however, needs to be evaluated. Strategies sustaining change post-implementation should be considered.

Objective To evaluate the effectiveness of directional atherectomy with a Phoenix atherectomy system in lower extremity peripheral arterial disease (LE-PAD). Materials and methods A retrospective review of subjects who had undergone atherectomy for severe and occluded LE-PAD. Demographic data, procedural properties, and follow-up information were recorded. The technical, procedural and clinical successes were reported. Results In total, 120 subjects were evaluated. The superficial femoral artery (SFA) group consisted of 64 subjects (53.3%), and the popliteal group consisted of 56 (46.7%) subjects. Groups did not differ in terms of age, gender, comorbid diseases and tobacco use. In both groups, four subjects (6.3% of SFA and 7.1% of the popliteal group) experienced extravasation was encountered in from the vessel during the procedure. During atherectomy, two (3.3%) of the subjects in the SFA group and one (1.9%) subject in the popliteal group experienced vessel dissection. Acute technical success in this study was 96.7% for SFA and 98.1% for the popliteal group. Overall technical success was 97.7%. In the first 72 h, three (5%) of the subjects in the SFA group and four (7.7%) of the subjects in the popliteal group experienced major adverse events. Acute procedural success in this study was 91.7% for SFA and 90.4% for the popliteal group. Overall procedural success was 91.1%. Success was defined as an improvement of at least one grade in the Rutherford classification; two (3.3%) subjects did not demonstrate improvements in the SFA group, and the clinical success rate was 96.7%. All subjects in the popliteal group demonstrated an improvement of at least one grade in the Rutherford classification, and clinical success was 100%. When the groups combined all subjects, the clinical success in this study was 98.2%. Conclusion Directional atherectomy with a Phoenix atherectomy system demonstrated comparable results with the literature.

Objective Acute limb ischemia is a common vascular emergency requiring immediate intervention. Thrombolysis has been widely utilized for acute limb ischemia; the purpose of this study is to analyze contemporary trends, outcomes and complications of thrombolysis for acute limb ischemia. Methods Patients were identified from the Nationwide Inpatient Sample (2003–2013) using ICD-9. Patients undergoing emergency thrombolysis for acute limb ischemia were evaluated. Three groups were analyzed: thrombolysis alone, thrombolysis and endovascular procedure (T+ENDO), and failed thrombolysis requiring open surgery (T+OPEN). Results A total of 162,240 patients with acute limb ischemia were estimated: 33,615 patients (20.7%) underwent thrombolysis as the initial treatment. Mean age was 66.2 ± 34.9 years with 54% male. The utilization of thrombolysis increased significantly during the study period (16.8–24.2%, p < 0.0001). The most common group was thrombolysis and endovascular procedure (40.7%), followed by thrombolysis alone (34.1%), and T+OPEN (25.2%). Thrombolysis and endovascular procedure increased significantly over time (31.6–47.8%, p < 0.0001) whereas thrombolysis alone and T+OPEN significantly decreased (39.6–28.6% and 28.7–23.6%, respectively, p < 0.0001). Overall mortality was 4.9%; thrombolysis and endovascular procedure compared to thrombolysis alone and T-OPEN had a lower mortality rate (3.2% vs. 6.1% and 5.9%, p < 0001). The overall stroke rate was 1.9%; thrombolysis alone had the highest stroke rate (3.0%, p < 0.0001) with thrombolysis and endovascular procedure the lowest (1.2%) and T+OPEN 1.7%. The highest amputation rate was T+OPEN (11.6%, p < 0.001) compared to thrombolysis and endovascular procedure (5.1%) and thrombolysis alone (5.3%). T+OPEN had the highest incidence of cardiac (5.5%), respiratory (7.3%) and renal complications (12.5%), pneumonia (4.0%), and fasciotomy (16.8%) (all p < 0.0001). Conclusion Thrombolysis remains an effective treatment for acute limb ischemia with increased utilization over time. There was a significant increase in thrombolysis and endovascular procedure leading to improved outcomes. Thrombolysis alone carried the highest mortality and stroke rate, with T+OPEN associated with the highest amputation and complications. Although thrombolysis is effective, 25% of patients required an open procedure suggesting that patient selection for thrombolysis first instead of open surgery continues to be a clinical challenge.
Initial outcomes of endovenous laser ablation with 1940 nm diode laser in the treatment of incompetent saphenous veins
Authors: Park Insoo 
Published: September 2018

Objectives To investigate the initial outcomes of 1940 nm diode laser in the treatment of incompetent saphenous veins. Methods This was a prospective observational study. We treated 89 patients with 160 incompetent saphenous veins using a 1940 nm diode laser and bare fiber. The laser’s power was set to 4.5 W with a mean linear endovenous energy density of 50.4 J/cm. Results The one-month closure rate was 100%. The post-procedural pain score at 6 h, 1 day, 10 days, and 1 month was 0.85 ± 1.04, 0.65 ± 1.01, 0.82 ± 1.25, and 0.47 ± 0.82, respectively. Complications encountered included paresthesia (3.8%) and thrombophlebitis (4.4%), whereas no cases of endovenous heat-induced thrombosis were observed. Conclusion The 1940 nm laser and bare fiber at 50.4 J/cm showed satisfactory initial outcomes with less pain and fewer complications, in the treatment of incompetent saphenous veins.
