    Antecedentes y finalidad: Los ácidos epoxyeicosatrienoic (EETs) son metabolitos del ácido araquidónico que desempeñan una función protectora contra procesos perjudiciales que pueden ocurrir después de re-oxigenación del injerto. Decidimos investigar si la presencia de polimorfismos funcionales en el gen que codifica el epóxido hidrolasa soluble (EPHX2), que metaboliza EETs a menos compuestos activos, pueden jugar un papel importante en el resultado del trasplante renal. Métodos En un grupo de 259 receptores caucásicos de trasplante renal y 183 donantes fallecidos, se determinó la presencia de tres EPHX2 común, a saber, los SNPs rs41507953 (K55R), rs751141 (R287Q) y rs1042032 A/G. Las asociaciones con los parámetros de la función del injerto y la incidencia de rechazo agudo fueron investigados retrospectivamente durante el primer año después del injerto mediante regresión logística, ajustándose a las variables clínicas y demográficas. Resultados Los portadores del genotipo rs1042032 GG muestran significativamente menor tasa de filtración glomerular estimada (eGFR) (38.15 ± 15.57 vs. 45.99 ± 16.05; p = 0,04) y mayores valores de creatinina sérica (1,57 ± 0,58 vs. 1,30 ± 0,47 g/dL; p=0.02) un año después del injerto, en comparación con los pacientes portadores del alelo A wildtype. El mismo genotipo GG también se asoció a un mayor riesgo de rechazo agudo. Curiosamente, esta asociación fue observada por el genotipo de ambos destinatarios [o =6.34 (1.35-29.90); p = 0,015] y donantes [OR = 5.53 (1.10 - 27.80); p=0,042]. Un modelo estadístico incluyendo ambos genotipos junto con otras variables demográficas y clínicas significativas se tradujo en un aumento de la importancia de la asociación con los receptores del genotipo [OR=8,28 (1.21-74.27); p=0,031]. Conclusiones Nuestros resultados indican que la variabilidad genética en el gen metabolizante de EETs, EPHX2, pueden tener un impacto significativo en los resultados del trasplante renal de donante fallecido.Background and Purpose: Epoxyeicosatrienoic acids (EETs) are arachidonic acid metabolites that play a protective role against damaging processes that may occur after re-oxygenation of the graft. We aimed to investigate whether the presence of functional polymorphisms in the gene encoding soluble epoxy hydrolase (EPHX2), which metabolizes EETs to less active compounds, may play a role in the outcome of renal transplantation. Methods In a group of 259 Caucasian renal transplant recipients and 183 deceased donors, we determined the presence of three common EPHX2 SNPs, namely rs41507953 (K55R), rs751141 (R287Q) and rs1042032 A/G. Associations with parameters of graft function and the incidence of acute rejection were retrospectively investigated throughout the first year after grafting by logistic regression adjusting for clinical and demographic variables. Results Carriers of the rs1042032 GG genotype displayed significantly lower estimated glomerular filtration rate (eGFR) (38.15 ± 15.57 vs. 45.99 ± 16.05; p = 0.04) and higher serum creatinine values (1.57 ± 0.58 vs. 1.30 ± 0.47 g/dL; p=0.02) one year after grafting, compared to patients carrying the wildtype A-allele. The same GG genotype was also associated to increased risk of acute rejection. Interestingly, this association was observed for the genotype of both recipients [OR =6.34 (1.35-29.90); p = 0.015] and donors [OR = 5.53 (1.10- 27.80); p=0.042]. A statistical model including both genotypes along with other meaningful demographic and clinical variables resulted in an increased significance for the association with the recipients’ genotype [OR=8.28 (1.21-74.27); p=0.031]. Conclusions Our results suggest that genetic variability in the EETs-metabolizing gene, EPHX2, may have a significant impact on the outcome of deceased-donor renal transplantation.• Asociación para el Estudio y la Prevención de las Enfermedades Renales (ASEPER), Badajoz • Junta de Extremadura, Consejería de Economía, Comercio e Innovación: Proyecto GR10022 • Red de Investigación Renal - REDINREN (Instituto de Salud Carlos III – Fondo Europeo de Desarrollo Regional – FEDER) : Ayudas a Eliecer Coto García, Carmen Díaz Corte y Carlos López LarreapeerReviewe

    Malaltia de Parkinson; Cuidador; Símptomes no motorsParkinson's disease; Caregiver; Non-motor symptomsEnfermedad de Parkinson; Cuidador; Síntomas no motoresBackground and objective: Recently, we demonstrated that staging Parkinson's disease (PD) with a novel simple classification called MNCD, based on four axes (motor, non-motor, cognition, and dependency) and five stages, correlated with disease severity and patients’ quality of life. Here, we analyzed the correlation of MNCD staging with PD caregiver's status. Patients and methods: Data from the baseline visit of PD patients and their principal caregiver recruited from 35 centers in Spain from the COPPADIS cohort from January 2016 to November 2017 were used to apply the MNCD total score (from 0 to 12) and MNCD stages (from 1 to 5) in this cross-sectional analysis. Caregivers completed the Zarit Caregiver Burden Inventory (ZCBI), Caregiver Strain Index (CSI), Beck Depression Inventory-II (BDI-II), PQ-10, and EUROHIS-QOL 8-item index (EUROHIS-QOL8). Results: Two hundred and twenty-four PD patients (63 ± 9.6 years old; 61.2% males) and their caregivers (58.5 ± 12.1 years old; 67.9% females) were included. The frequency of MNCD stages was 1, 7.6%; 2, 58.9%; 3, 31.3%; and 4–5, 2.2%. A more advanced MNCD stage was associated with a higher score on the ZCBI (p < .0001) and CSI (p < .0001), and a lower score on the PQ-10 (p = .001), but no significant differences were observed in the BDI-II (p = .310) and EUROHIS-QOL8 (p = .133). Moderate correlations were observed between the MNCD total score and the ZCBI (r = .496; p < .0001), CSI (r = .433; p < .0001), and BDI-II (r = .306; p < .0001) in caregivers.Conclusion: Staging PD according to the MNCD classification is correlated with caregivers’ strain and burden.Fundación Española de Ayuda a la Investigación en Enfermedades Neurodegenerativas y/o de Origen Genético; Alpha Bioresearch; Spanish Ministry of Economy and Competitiveness, Grant/Award Number: PI16/0157

    During last months, there have been a significant increase in the evidences showing the catastrophic health situation in Venezuela. There are multiple epidemics, increase in emerging and reemerging infectious, tropical and parasitic diseases as consequences of the social, economic and political crises, which would be considered today a clearly anthropogenic disaster. Venezuela is facing in 2019, the worse sanitary conditions, with multiple implications for public health and travel medicine. So far, from a global perspective, this situation will be an impediment for the achievement of the sustainable development goals (SDG) in 2030. In this multiauthor review, there is a comprehensive analysis of the situation for infectious diseases, non-communicable diseases, their impact in the Americas region, given the migration crisis as well as the comparative status of the SDG 2030. This discussion can provide input for prioritizing emerging health problems and establish a future agenda

    Background: Recently, a novel simple classification called MNCD, based on 4 axes (Motor; Non-motor; Cognition; Dependency) and 5 stages, has been proposed to classify Parkinson's disease (PD). Objective: Our aim was to apply the MNCD classification in a cohort of PD patients for the first time and also to analyze the correlation with quality of life (QoL) and disease severity. Methods: Data from the baseline visit of PD patients recruited from 35 centers in Spain from the COPPADIS cohort from January 2016 to November 2017 were used to apply the MNCD classification. Three instruments were used to assess QoL: 1) the 39-item Parkinson's disease Questionnaire [PDQ-39]); PQ-10; the EUROHIS-QOL 8-item index (EUROHIS-QOL8). Results: Four hundred and thirty-nine PD patients (62.05 +/- 7.84 years old; 59% males) were included. MNCD stage was: stage 1, 8.4% (N = 37); stage 2, 62% (N = 272); stage 3, 28.2% (N = 124); stage 4-5, 1.4% (N = 6). A more advanced MNCD stage was associated with a higher score on the PDQ39SI (p < 0.0001) and a lower score on the PQ-10 (p < 0.0001) and EUROHIS-QOL8 (p < 0.0001). In many other aspects of the disease, such as disease duration, levodopa equivalent daily dose, motor symptoms, non-motor symptoms, and autonomy for activities of daily living, an association between the stage and severity was observed, with data indicating a progressive worsening related to disease progression throughout the proposed stages. Conclusion: Staging PD according to the MNCD classification correlated with QoL and disease severity. The MNCD could be a proper tool to monitor the progression of PD
