Our results demonstrated that CSCA was negatively and moderately correlated with EDSS scores (rs = -0.42, 95% CI -0.51 to -0.32; p less then 0.0001). Subgroup analyses revealed a weaker correlation in the group of relapsing-remitting multiple sclerosis (RRMS) and clinically isolated syndrome (CIS) (rs = -0.19, 95% CI -0.31 to -0.07; p = 0.0029). CONCLUSIONS The correlation between CSCA and EDSS scores was significant but moderate. We encourage more studies using reliable and consistent methods to explore whether CSCA is suitable as a predictor for MS progression. V.BACKGROUND Recent data on rates of cardiovascular disease (CVD) in patients after MS diagnosis are sparse. OBJECTIVE To describe incident CVD in MS patients after diagnosis compared with a matched non-MS population. METHODS We conducted a matched cohort study in two separate electronic medical databases, the United States Department of Defense military health care system and the United Kingdom's Clinical Practice Research Datalink GOLD. The study population included all patients with a first recorded diagnosis of MS and no history of CVD or selected measurable comorbidities associated with CVD and matched non-MS patients who were also free of CVD and the CVD associated comorbidities. We identified incident CVD outcomes first recorded after the MS diagnosis / matched date and calculated incidence rates and incidence rate ratios by type of CVD. RESULTS Rates of venous thromboembolism and peripheral vascular disease were 2-fold higher among MS than non-MS patients in both databases and the risk of myocardial infarction was 2.5 times higher among female MS patients compared with non-MS females in both databases. Other CVD outcomes were not consistent between databases. CONCLUSION MS patients in the UK and the US have increased risk of venous thromboembolism and peripheral vascular disease. The risk of myocardial infarction is increased among female MS patients. V.Recent studies implicate B cells in multiple sclerosis (MS) pathogenesis, and consequently, several molecules participating in B cell survival and proliferation, including B-cell activating factor (BAFF), have recently been analyzed in MS patients. BAFF mediates its function through binding to three receptors; among them, its interaction with the BAFF receptor (BAFFR) is crucial in mediating its survival function. Interestingly, two common polymorphisms of the TNFRSF13C gene, encoding BAFFR, P21R (rs77874543) and H159Y (rs61756766), have been reported to affect BAFFR assembly and signaling. In order to evaluate the possible contribution of BAFFR in MS pathogenesis and/or phenotype, we analyzed both TNFRSF13C/BAFFR polymorphisms in 486 MS patients in relation to their disease severity, their disability status and the age of disease onset and duration. As control group, we used allele frequencies extracted from the Exome Aggregation Consortium (ExAC) Browser. Interestingly, we found a higher prevalence of the H159Y polymorphism in MS patients, suggesting that enhanced BAFFR-signaling might contribute to the disease pathogenesis. Immunoglobulin G (IgG) autoantibodies targeting myelin oligodendrocyte glycoprotein (MOG) have recently been associated with autoimmune CNS demyelination. We present the case of a 35-year-old patient who was seronegative for MOG-IgG (as confirmed by means of three independent immunoassays) during two corticosteroid-responsive attacks of brainstem encephalitis and optic neuritis, respectively, but turned positive for MOG-IgG under treatment with interferon-beta (IFN-beta), which was commenced 6 months after onset of the first attack. MOG-IgG serum levels declined after therapy was switched to glatiramer acetate. The fact that seroconversion was first observed under treatment with IFN-beta is in accordance with previous evidence suggesting a role of IFN-beta in disease exacerbation in antibody-mediated disorders. BACKGROUND Memory impairment is one of the most frequently and early detected impairment in multiple sclerosis (MS) patients. Several authors have argued that when a failure occurs in the retrieval of lexical information, this might be due to a reduction of the lexical pool, related to semantic memory. Here we further investigated memory alteration in MS patients, by focusing on memory distortions (i.e., false memories) for semantically-related material. METHODS A group of 40 consecutive relapsing remitting MS (RRMS) patients and a matched control group of 40 healthy controls performed the Deese-Roediger-McDermott (DRM), a false memory task for lists of associated words. RESULTS At recall, RRMS patients reported a reduced number of false recalls for semantically-related but non-presented items (i.e., critical false recalls) compared to HCs; at recognition, RRMS patients showed a reduced level of confidence for false recognitions of critical items. CONCLUSION We found a reduced susceptibility to false memories in RRMS patients compared to HCs. The potential mechanisms underlying this effect are discussed in light of the alterations in the structure of semantic memory. INTRODUCTION The implantation of a penile prosthesis is considered a third-line treatment and is indicated in patients who do not respond adequately to pharmacotherapy or require definitive treatment. Currently, the most used devices are 3-component penile prostheses, which presently account for more than 90% of the implants used. MATERIAL AND METHODS We reviewed the evidence and the recommendations of the clinical practice guidelines regarding surgery in patients with erectile dysfunction. RESULTS The recommendations of the clinical practice guidelines on surgery in patients with erectile dysfunction are summarized as follows men with erectile dysfunction should be informed about the option of penile prosthesis implant treatment, commenting on the benefits, risks and consequences; men with erectile dysfunction who have agreed to receive penile prosthesis should be advised on post-surgical expectations; penile prosthesis implants should not be performed in patients with systemic, cutaneous or urinary tract infection; in young men with erectile dysfunction and focal penile or pelvic arterial obstruction who do not have generalized vascular disease or veno-occlusive dysfunction, penile arterial reconstruction can be considered; in men with erectile dysfunction, penile venous surgery is not recommended. CONCLUSIONS The use of penile prostheses offers high satisfaction rates to both the patient and his partner. However, it is crucial to adequately inform and warn patients about possible complications and consequences. Highly efficient and sustainable conversion technologies to generate uniform sodalite (Na8(AlSiO4)6(OH)2) zeolite microspheres with low-grade waste natural diatomite as raw materials via a solution-mediated crystallization route were developed in the present study. The synthesis process can be considered as an in-situ zeolitization of diatomite precursor without involving any mesoscale template and any post-synthetic modification. The mass ratios of diatomite and AlCl3·6H2O have remarkable effect on the morphology, crystal structure and porosity of sodalite zeolite product. Marizomib inhibitor The preferred sodalite microspheres with uniform mesoporous of size 3.5-5.5 nm and large surface area of 162.5 m2/g exhibit well removal performance for heavy metal ions (Pb(II), Cd(II), Zn(II), and Cu(II)), with the highest adsorption abilities for Pb(II) ions of 365 mg/g. In addition, the effect of contact time, initial ion concentration, competitive adsorption and solution pH were evaluated. The removal performance results from synergistic effects of dominating cation-exchange and additional surface chemisorption. The study may broadly help unveil chemical control reactions of the zeolitization processes of diatomite, and thus facilitates the development of promising zeolite materials for the use in natural and engineered aquatic environments by recycling waste diatomite resources. V.The widespread use of nano-enabled water treatment composites (NWTCs) can result in the release of nanoparticles (NPs) into environmental waters. Studying the release of NPs from NWTCs is of great significance for evaluating the material stability, and environment and biological safety. This work evaluated the amount and species of Zr released from a NWTC, a ZrO2/polymer composite (HZO@D201), during the treatment of electroplating wastewater. About 5 g of the HZO@D201 particles, consisting of porous spheres (0.8 mm in diameter) loaded with ZrO2 NPs, were packed into a glass column (130 mm in length and 20 mm in diameter) and treated with wastewater at a flow rate of 25 mL/hr. The release of Zr occurred mainly in the initial stages of water treatment, decreased with the increase of treatment volume, and approached an equilibrium value of approximately 3.79 μg/L at the treatment volume of about 800 bed volumes. The total amount of Zr released in the effluent was in the range of 2.62-140 μg/L, which was mainly present in the form of ZrO2 NPs. The amounts of Zr released under acidic and alkaline conditions were markedly higher than that under neutral conditions, while the presence of humic acid significantly inhibited the release of Zr. Our study implied that the NWTCs could be a source of engineered NPs in environmental waters, and should be considered in evaluating the safety of ZrO2/polymer composites in water treatment. V.The effects of four conditioning approaches Acid, Acid-zero-valent iron (ZVI)/peroxydisulfate (PMS), Fe(II)/PMS and ZVI/PMS, on wastewater activated sludge (WAS) dewatering and organics distribution in supernatant and extracellular polymeric substances (EPS) layers were investigated. The highest reduction in bound water and the most WAS destruction was achieved by Acid-ZVI/PMS, and the optimum conditions were pH 3, ZVI dosage 0.15 g/g dry solid (DS), oxone dosage 0.07 g/g DS and reaction time 10.6 min with the reductions in capillary suction time (CST) and water content (Wc) as 19.67% and 8.49%, respectively. Four conditioning approaches could result in TOC increase in EPS layers and supernatant, and protein (PN) content in tightly bound EPS (TB-EPS). After conditioning, organics in EPS layers could migrate to supernatant. Polysaccharide (PS) was easier to migrate to supernatant than PN. In addition, Acid, Acid-ZVI/PMS or Fe(II)/PMS conditioning promoted the release of some polysaccharides containing ring vibrations v PO, v C-O-C, v C-O-P functional groups from TB-EPS. ESR spectra proved that both radicals of SO4-· and ·OH contributed to dewatering and organics transformation and migration. CST value of WAS positively correlated with the ratios of PN/PS in LB-EPS and total EPS, while it negatively correlated with TOC, PN content and PS content in TB-EPS, as well as PS content in supernatant and LB-EPS. BWC negatively correlated to zeta potential and TOC value, PN content, and HA content in supernatant. V.Ion-exchange polymer and modified carbonization bacterial cellulose (CBC) electrodes were fabricated using varying amounts of cation-exchange polymers (glutaric acid (GA) and sulfosuccinic acid (SSA)) and assembled within an asymmetric capacitive deionization unit (p-CDI). The performance of selective NO2- electro-adsorption was studied. The AC/CBC-SSA group showed a better salt adsorption capacity (14.56 mg/g) and nitrite removal efficiency (71.01%) than the AC/CBC-GA (10.72 mg/g, 47.83%) and AC/AC (4.81 mg/g, 12.74%) groups. It was confirmed that the CBC-SSA/GA electrodes enhanced nitrite selectivity and increased the adsorption capacity, and the total amounts of adsorbed anions increased when the applied voltage was increased from 0.8 to 1.2 V, while the molar fraction of nitrate decreased. The competitive and preferential adsorption of anions was further investigated using different binary solutions of anions and occurred in the following sequence NO2- >SO42- >NO3- >F-≈ Cl-. Furthermore, the p-CDI units were applied to remove nitrite in real wastewater samples, and the results showed that they had excellent reusability and application for use in dyeing wastewater treatment.
