SWOT Analysis Approach for Advancement of Waste-to-energy Cluster in Latvia

AbstractIt is important to improve the communication and collaboration of waste-to-energy stakeholders in Latvia to ensure sustainable economic and environmental development and promote innovation and local technology development. Therefore, implementation of a waste-to-energy cluster in Latvia has been proposed. The aim of this paper is to provide a comparative analysis of the organizational structure and SWOT analysis of five existing and one potential waste-to-energy cluster and develop suggestions for improved organization of the developing Latvian cluster. The analytical part includes SWOT analysis of the proposed Latvian waste-to-energy cluster and a comparison of its results with five SWOT analyses for existing European waste-to-energy clusters involved in the project COOLSWEEP

Neurofilament light chain level is a weak risk factor for the development of MS

Altres ajuts: T Jens Kuhle was supported by an ECTRIMS Research Fellowship Programme and by the Forschungsfonds of the University of Basel, Switzerland.To determine the prognostic value of selected biomarkers in clinically isolated syndromes (CIS) for conversion to multiple sclerosis (MS) and disability accrual. Data were acquired from 2 CIS cohorts. The screening phase evaluated patients developing clinically definite MS (CIS-CDMS) and patients who remained as CIS during a 2-year minimum follow-up (CIS-CIS). We determined levels of neurofascin, semaphorin 3A, fetuin A, glial fibrillary acidic protein, and neurofilament light (NfL) and heavy chains in CSF (estimated mean [95% confidence interval; CI]). We evaluated associations between biomarker levels, conversion, disability, and magnetic resonance parameters. In the replication phase, we determined NfL levels (n = 155) using a 900 ng/L cutoff. Primary endpoints in uni- and multivariate analyses were CDMS and 2010 McDonald MS. The only biomarker showing significant differences in the screening was NfL (CIS-CDMS 1,553.1 [1,208.7-1,897.5] ng/L and CIS-CIS 499.0 [168.8-829.2] ng/L, p < 0.0001). The strongest associations were with brain parenchymal fraction change (r = −0.892) and percentage brain volume change (r = −0.842) at 5 years. NfL did not correlate with disability. In the replication phase, more NfL-positive patients, according to the cutoff, evolved to MS. Every 100-ng/L increase in NfL predicted CDMS (hazard ratio [HR] = 1.009, 95% CI 1.005-1.014) and McDonald MS (HR = 1.009, 95% CI 1.005-1.013), remaining significant for CDMS in the multivariate analysis (adjusted HR = 1.005, 95% CI 1.000-1.011). This risk was lower than the presence of oligoclonal bands or T2 lesions. NfL is a weak independent risk factor for MS. Its role as an axonal damage biomarker may be more relevant as suggested by its association with medium-term brain volume changes

First Report of the Hyper-IgM Syndrome Registry of the Latin American Society for Immunodeficiencies: Novel Mutations, Unique Infections, and Outcomes

Hyper-IgM (HIGM) syndrome is a heterogeneous group of disorders characterized by normal or elevated serum IgM levels associated with absent or decreased IgG, IgA and IgE. Here we summarize data from the HIGM syndrome Registry of the Latin American Society for Immunodeficiencies (LASID). of the 58 patients from 51 families reported to the registry with the clinical phenotype of HIGM syndrome, molecular defects were identified in 37 patients thus far. We retrospectively analyzed the clinical, immunological and molecular data from these 37 patients. CD40 ligand (CD40L) deficiency was found in 35 patients from 25 families and activation-induced cytidine deaminase (AID) deficiency in 2 unrelated patients. Five previously unreported mutations were identified in the CD40L gene (CD40LG). Respiratory tract infections, mainly pneumonia, were the most frequent clinical manifestation. Previously undescribed fungal and opportunistic infections were observed in CD40L-deficient patients but not in the two patients with AID deficiency. These include the first cases of pneumonia caused by Mycoplasma pneumoniae, Serratia marcescens or Aspergillus sp. and diarrhea caused by Microsporidium sp. or Isospora belli. Except for four CD40L-deficient patients who died from complications of presumptive central nervous system infections or sepsis, all patients reported in this study are alive. Four CD40L-deficient patients underwent successful bone marrow transplantation. This report characterizes the clinical and genetic spectrum of HIGM syndrome in Latin America and expands the understanding of the genotype and phenotype of this syndrome in tropical areas.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Jeffrey Modell FoundationLatin American Advisory Board on Primary Immunodeficiencies initiativeUniv São Paulo, Inst Biomed Sci, Dept Immunol, BR-05508000 São Paulo, BrazilCtr Invest & Estudios, Dept Biomed Mol, Mexico City, DF, MexicoDr Ricardo Gutierrez Childrens Hosp, Buenos Aires, DF, ArgentinaHosp Nacl Ninos Dr Carlos Saenz Herrera, San Jose, Costa RicaPediat Allergy & Immunol Clin, Caxias Do Sul, RS, BrazilAlbert Sabin Hosp, Fortaleza, Ceara, BrazilHosp Base Dist Fed, Brasilia, DF, BrazilIntegrated Ctr Pediat Specialties, Curitiba, PR, BrazilHosp Ninos VJ Vilela, Rosario, ArgentinaHosp Ninos Luis Calvo Mackenna, Santiago, ChileUniv Fed Parana, Dept Pediat, BR-80060000 Curitiba, Parana, BrazilUniv Estadual Campinas, Sch Med, Dept Pediat, Campinas, SP, BrazilConceicao Childrens Hosp, Dept Pediat, Div Allergy & Immunol, Porto Alegre, RS, BrazilChildrens Hosp Lucidio Portela, Teresina, PI, BrazilPontificia Univ Catolica Chile, Div Pediat, Santiago, ChileUniv Estadual Campinas, Sch Med, Dept Med, Campinas, SP, BrazilUniv São Paulo, Ribeirao Preto Med Sch, BR-14049 Ribeirao Preto, SP, BrazilHosp Nacl Edgardo Rebagliati Martins Alergia & In, Lima, PeruUniv Fed Rio de Janeiro, Sch Med, Dept Pediat, Rio de Janeiro, BrazilInst Nacl Pediat, Unidad Invest Inmunodeficiencias, Mexico City, DF, MexicoIMSS, Unidad Med Alta Especialidad 25, Monterrey, Nuevo Leon, MexicoClin Montefiori, Unidad Inmunol, Lima, PeruUNAL, Univ Hosp, Monterrey, Nuevo Leon, MexicoFac Med ABC, Santo Andre, SP, BrazilChildrens Hosp, Dept Pediat, New Orleans, LA USAHop Necker Enfants Malad, INSERM, Unite U768, Paris, FranceUniv Washington, Sch Med, Dept Pediat, Seattle, WA 98195 USASeattle Childrens Res Inst, Seattle, WA USAUniversidade Federal de São Paulo, Dept Pediat, Div Allergy Immunol & Rheumatol, São Paulo, BrazilUniversidade Federal de São Paulo, Dept Pediat, Div Allergy Immunol & Rheumatol, São Paulo, BrazilFAPESP: 2012/50515-4FAPESP: 2006/57643-7FAPESP: 2012/51745-3Web of Scienc
