EPITRANS. Quality assessment of the epilepsy transition process.

OBJECTIVE: To analyze the differences in clinical management during the epilepsy transition process from pediatric to adult care and to determine the quality of life and degree of satisfaction of patients and caregivers during the transition. METHODS: This is a longitudinal study including patients with epilepsy transferred from pediatric to adult epilepsy care between 2013 and 2017. Patients had a minimum follow-up of 3 years before the transition visit and at least 3 years consulting in the adults section. Clinical characteristics were retrieved from the medical chart. Quality of life and satisfaction questionnaires were administered by online access to patients and caregivers at the end of the adult follow-up period. RESULTS: 99 patients (50.5 % women, mean transition age 16.5 ± 1 years old) were included. Before the transition visit, 90 % of patients received a transition discussion and 88 % had a formal clinical report. In the pediatric period, patients were visited more frequently, had more EEGs and genetic studies, and were seen by the same neuropediatrician (P<0.05). In the adult period, patients underwent a larger number of prolonged video EEGs and were prescribed polytherapy more often (P<0.05). Quality of life remained steady during the entire transition, but satisfaction with the care received was significantly higher during the pediatric period. CONCLUSIONS: Significant differences were seen in epilepsy care during transition from pediatric to adult management, and this had an impact on the degree of satisfaction reported by patients and caregivers. Our results provide evidence of the potential value of development and early implementation of a protocolled transition program.

Implicaciones de iniciar fármacos antiepilépticos previo a la realización de EEG en primeras crisis epilépticas / Implications of initiating antiseizure drugs prior to the performance of EEG in first epileptic seizures

Introducción: Determinar si la administración de fármacos antiepilépticos (FAE) puede alterar la probabilidad de encontrar anomalías epileptiformes en EEG realizados de forma precoz tras una primera crisis epiléptica (CE). Método: Estudio observacional retrospectivo en el que se incluyó a los pacientes atendidos en urgencias de nuestro centro por una primera CE entre julio del 2014 y noviembre del 2019. Se recogieron los datos clínicos, las características técnicas de adquisición e interpretación de los EEG efectuados durante las primeras 72 h tras la CE y los factores relacionados con la recurrencia. Resultados: Se recogieron 155 pacientes; edad media 48,6 ±22,5 años; 61,3% hombres. El 51% presentó crisis tónico-clónicas de inicio desconocido y el 12% focales con progresión a tónico-clónica bilateral. El 25,2% (39/155) recibió tratamiento con FAE antes de la realización del EEG; en 33 pacientes se administró un FAE no benzodiacepínico y en 6 una benzodiacepina. Se observaron anomalías epileptiformes en 29,7% de los pacientes. La administración previa de FAE no se asoció de forma significativa ni con la probabilidad de detectar anomalías epileptiformes (p = 0,25) ni con el riesgo de recurrencia a los 6 meses (p = 0,63). Conclusiones: La administración de un FAE previo a la realización del EEG precoz tras una primera CE no disminuye la probabilidad de detectar anomalías epileptiformes. Estos hallazgos sugieren que iniciar un FAE de forma inmediata en aquellos pacientes con alto riesgo de recurrencia precoz no implica un menor rendimiento diagnóstico de dicha prueba.(AU)

Introduction: This study aimed to determine whether the administration of antiepileptic drugs (AED) alters the likelihood of detecting epileptiform abnormalities in electroencephalographies (EEG) performed early after a first epileptic seizure. Method: We performed a retrospective, observational study including patients with a first seizure attended at our centre's emergency department between July 2014 and November 2019. We collected clinical data, as well as technical data on the acquisition and interpretation of the EEG performed within the first 72 hours after the seizure, and the factors related with seizure recurrence. Results: We recruited 155 patients with a mean (SD) age of 48.6 (22.5) years; 61.3% were men. Regarding seizure type, 51% presented tonic-clonic seizures of unknown onset and 12% presented focal to bilateral tonic-clonic seizures. Thirty-nine patients (25.2%) received AED treatment before the EEG was performed: 33 received a non-benzodiazepine AED and 6 received a benzodiazepine. Epileptiform abnormalities were observed in 29.7% of patients. Previous administration of AEDs was not significantly associated with the probability of detecting interictal epileptiform abnormalities (P=.25) or with the risk of recurrence within 6 months (P=.63). Conclusions: Administration of AEDs before an early EEG following a first seizure does not decrease the likelihood of detecting epileptiform abnormalities. These findings suggest that starting AED treatment immediately in patients with a high risk of early recurrence does not imply a reduction in the diagnostic accuracy of the test.(AU)

These findings suggest that starting AED treatment immediately in patients with a high risk of early recurrence does not imply a reduction in the diagnostic accuracy of the test.

Valor pronóstico de los biomarcadores licuorales en el deterioro cognitivo leve debido a enfermedad de Alzheimer / Prognostic value of cerebrospinal fluid biomarkers in mild cognitive impairment due to Alzheimer disease

Realizamos un análisis retrospectivo de los pacientes evaluados en nuestra unidad de memoria en los que se realizó determinación de biomarcadores licuorales de enfermedad de Alzheimer (EA). Se seleccionaron aquellos casos con diagnóstico de deterioro cognitivo leve debido a EA según criterios clínicos (criterios NIA-AA), déficit neuropsicológico comprobado, una puntuación igual a 3 en la escala GDS y un perfil alterado de biomarcadores en líquido cefalorraquídeo. De los 588 casos revisados, 110 cumplieron los criterios de inclusión. Durante el seguimiento, 50 de estos 110 casos (45,45%) progresaron a demencia por EA. Se observaron diferencias significativas en los niveles basales de tau total y tau fosforilada entre los casos que evolucionaron a demencia y los que permanecieron estables como deterioro cognitivo leve, siendo los niveles más altos en el grupo que progresó a demencia. Después del ajuste por edad, sexo, antecedentes de hipertensión, diabetes y nivel educativo, un aumento del 10% en los valores de proteína tau total se asoció con un aumento del 7,60% en el riesgo de progresión a demencia (HR = 2,22, IC 95% [1,28, 3,84], p = 0,004). En pacientes con deterioro cognitivo leve debido a EA un perfil alterado de biomarcadores licuorales, concentraciones progresivamente mayores de tau-t y tau-p se asocian a un mayor riesgo de conversión a demencia.(AU)

We performed a retrospective analysis of the patients assessed at our memory unit for whom Alzheimer disease (AD) cerebrospinal fluid biomarker results were available. We selected patients diagnosed with mild cognitive impairment due to AD (National Institute on Aging-Alzheimer's Association clinical criteria), confirmed neuropsychological deficit, a Global Deterioration Scale score of 3, and an abnormal profile of cerebrospinal fluid biomarkers. Of the 588 cases reviewed, 110 met the inclusion criteria. During follow-up, 50 cases (45.45%) progressed to dementia due to AD. Baseline levels of total and phosphorylated tau were higher in the group of patients that progressed to dementia than in those remaining with mild cognitive impairment. After adjusting for age, sex, history of hypertension, diabetes, and educational level, a 10% increase in total tau protein values was associated with a 7.60% increase in the risk of progression to dementia (hazard ratio: 2.22; 95% confidence interval, 1.28-3.84]; P = .004). Among patients with mild cognitive impairment due to AD and abnormal cerebrospinal fluid biomarker profiles, progressively higher concentrations of total or phosphorylated tau were associated with increased risk of progression to dementia.(AU)

Odor emission assessment of different WWTPs with Extended Aeration Activated Sludge and Rotating Biological Contactor technologies in the province of Cordoba (Spain).

In this study, five urban WWTPs (Wastewater Treatment Plant) with different biological treatment (Extended Aeration Activated Sludge - EAAS; Rotating Biological Contactor - RBC), wastewater type (Urban; Industrial) and size, were jointly evaluated. The aim was twofold: (1) to analyze and compare their odor emissions, and (2) to identify the main causes of its generation from the relationships between physico-chemical, respirometric and olfactometric variables. The results showed that facilities with EAAS technology were more efficient than RBC, with elimination yields of organic matter higher than 90%. In olfactometric terms, sludge managements facilities (SMFs) were found to be the critical odor source in all WWTPs compared to the Inlet point (I) or Post primary treatment (PP), and for seasonal periods with ambient temperature higher than 25 °C. Moreover, the global odor emissions quantified in all SMFs revealed that facilities with EAAS (C-WWTP, V-WWTP and Z-WWTP) had a lower odor contribution (19,345, 14,800 and 11,029 ouE/s·m2, respectively) than for those with RBC technology (P-WWTP and NC-WWTP) which accounted for 19,747 ouE/s·m2 and 80,061 ouE/s·m2, respectively. In addition, chemometric analysis helped to find groupings and differences between the WWTPs considering the wastewater (71.27% of total variance explained) and sludge management (64.52% of total variance explained) lines independently. Finally, odor emissions were adequately predicted from the physico-chemical and respirometric variables in the wastewater (r2 = 0.8738) and sludge (r2 = 0.9373) lines, being pH, volatile acidity and temperature (wastewater line), and pH, moisture, temperature, SOUR (Specific Oxygen Uptake Rate) and OD20 (Cumulative Oxygen Demand at 20 h) (sludge line) the most influential variables.

Extensive pharmacokinetic variability of Levetiracetam. ¿Are doctors aware?

INTRODUCTION: Levetiracetam was presented as a drug with linear pharmacokinetics. There is currently evidence on its extensive pharmacokinetic variability in real clinical practice. OBJECTIVE: To describe levetiracetam pharmacokinetic variability in patients with epilepsy in real clinical practice. To evaluate the effect on levetiracetam levels of gender, age, renal function, and polytherapy. To describe how clinicians prescribe based on age and co-medication. METHODS: Retrospective analysis of epilepsy patients treated with levetiracetam for whom plasma levels were available. RESULTS: 151 patients. Median levetiracetam level of 17.75 mg/L, median dose of 2000 mg/day. There was a significant correlation between daily dose and serum levels (p < 0.01). There was a 18.1% increase in levetiracetam concentration/dose ratio in patients over 65 years of age (p < 0.05) that also correlated with decreased glomerular filtration (p < 0.01). Clinicians corrected doses so patients over 65 years had similar levels than younger patients. There was a 30.1% decrease of concentration/dose ratio in patients on polytherapy with potent enzyme inducer antiseizure medication (p < 0.05), and a 46.3% decrease for carbamazepine (p < 0.01). Clinicians did not correct doses, so patients treated with levetiracetam and carbamazepine had 27.5% lower levels than patients taking other polytherapy. CONCLUSION: The pharmacokinetic variability of levetiracetam is wider than originally thought. Age and co-medication with strong enzyme-inducing drugs, especially carbamazepine, significantly influence levetiracetam levels. Clinicians at our center did not consider this interaction and prescribed similar doses of levetiracetam when it was used in combination with these drugs or with others, so they probably were not aware of this interaction.

Epileptic seizures in the emergency room: clinical and electroencephalographic findings associated with brain perfusion patterns on computed tomography.

BACKGROUND: Diagnosis of epileptic seizures, particularly regarding status epilepticus (SE), may be challenging in an emergency room setting. The aim of the study was to study the diagnostic yield of perfusion computed tomography (pCT) in patients with single epileptic seizures and SE. METHODS: We retrospectively reviewed the records of patients who followed an acute ischemic stroke pathway during a 9-month period and who were finally diagnosed with a single epileptic seizure or SE. Perfusion maps were visually analyzed for the presence of hyperperfusion and hypoperfusion. Clinical data, EEG patterns, and neuroimaging findings were compared. RESULTS: We included 47 patients: 20 (42.5%) with SE and 27 (57.5%) with single epileptic seizure. Of 18 patients who showed hyperperfusion on pCT, 12 were ultimately diagnosed with SE and eight had EEG findings compatible with an SE pattern. Focal hyperperfusion on pCT had a sensitivity of 60% (95% CI 36.4-80.2) and a specificity of 77.8% (95% CI 57.2-90.6) for predicting a final diagnosis of SE. The presence of cerebral cortical and thalamic hyperperfusion had a high specificity for predicting SE presence. Of note, 96% of patients without hyperperfusion on pCT did not show an SE pattern on early EEG. CONCLUSIONS: In acute settings, detection by visual analysis of focal cerebral cortical hyperperfusion on pCT in patients with epileptic seizures, especially if accompanied by the highly specific feature of thalamic hyperperfusion, is suggestive of a diagnosis of SE and requires clinical and EEG confirmation. The absence of focal hyperperfusion makes a diagnosis of SE unlikely.

The social and occupational consequences of the COVID-19 pandemic among patients with multiple sclerosis in three distinct populations: A web-based cross-sectional survey.

Background: The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes the disease COVID-19, has caused a pandemic that has rapidly affected the whole world and caused a significant threat to public health. The aim of this study was to investigate and analyze the social and occupational effects of the COVID-19 pandemic on patients with multiple sclerosis (MS) in three different countries: China, Spain, and Cuba. Methods: A cross-sectional survey was designed to assess the social and occupational effects of the COVID-19 pandemic in MS patients in these three countries, using a 25-item anonymous online questionnaire, structured into three sections. Quantitative data are expressed as mean (standard deviation), and quantitative data as absolute frequency and percentage. Results: A total of 361 participants responded to the questionnaire: 194 from China, 104 from Spain, and 63 from Cuba. We found no cases of COVID-19 among Chinese patients with MS, and few cases in Spain and Cuba. Respondents reported different levels of impact on relationships with friends, family, and colleagues, and patients in all three countries described increased use of digital or social media platforms. Spanish patients reported a significantly less negative impact than those in Cuba and China. Mental and cognitive effects were similar in all three countries, although China seemed to have a better situation. We also found that the time spent exercising decreased at specific points during the pandemic, but with few changes in dietary habits. Patients reported little or no change in their means of transport in all three countries. Most patients in all three countries reported little or no physical deterioration, especially in Chinese patients (82.47%), compared to the Spanish (70.20%) and Cuban respondents (73.02%). In general, patients from all three countries demonstrated confidence in overcoming the COVID-19 pandemic, although to a lesser extent among Spanish respondents. Conclusions: During the pandemic, family support was more effective in China than in Cuba and Spain. Neither COVID-19 infections nor the number of MS relapses increased significantly during lockdown in any of the three countries. Regarding their economic situation, Spanish MS patients reported a significantly less severe negative impact than those in Cuba and China. Patients from all three countries used digital or social media platforms more frequently, probably to maintain personal relationships. Chinese and Cuban respondents were more confident of the control of the pandemic than the Spanish, who were more pessimistic.

Introducción: El nuevo coronavirus de tipo 2, causante del síndrome respiratorio agudo severo o COVID-19, se ha expandido rápidamente a nivel mundial, convirtiéndose en una grave amenaza para la salud pública en forma de pandemia. El objetivo de este estudio es analizar los efectos sociolaborales de la pandemia de COVID-19 en pacientes con esclerosis múltiple (EM) en 3 países diferentes (China, España y Cuba). Métodos: Diseñamos un estudio transversal para valorar los efectos sociolaborales de la pandemia de COVID-19 en pacientes con EM procedentes de China, España y Cuba mediante un cuestionario digital de 25 preguntas divididas en 3 apartados. Los datos cuantitativos se expresan como medias y desviaciones estándar, mientras que los datos cualitativos se expresan mediante valores y porcentajes. Resultados: Un total de 361 pacientes respondieron al cuestionario (194 de China, 104 de España y 63 de Cuba). No encontramos ningún paciente chino con EM que hubiera padecido COVID-19, y los casos diagnosticados en España y Cuba fueron muy infrecuentes. A raíz de la pandemia, se observaron cambios en las relaciones con amigos, familiares y compañeros; además, los pacientes con EM usaron plataformas digitales y redes sociales con más frecuencia en los 3 países. El impacto negativo fue significativamente menor en España que en Cuba o China. Los efectos mentales y cognitivos de la pandemia fueron similares en los 3 países, aunque parece que la situación previa era mejor en China. Igualmente, observamos que el tiempo dedicado al ejercicio se redujo en momentos específicos durante la pandemia. Por el contrario, no se detectaron grandes cambios en los hábitos alimentarios. Los pacientes de los 3 países consideraron que no se produjeron cambios en su medio de transporte, o que estos fueron escasos. La mayoría de los pacientes ha experimentado poco o ningún deterioro físico, particularmente los pacientes chinos (82,47%) en comparación con los españoles (70,20%) y cubanos (73,02%). En líneas generales, todos los pacientes se mostraron esperanzados en superar la pandemia, aunque los pacientes españoles en menor grado. Conclusiones: Durante la pandemia, el apoyo familiar fue más importante en China que en Cuba o España. En ninguno de los 3 países se observó un aumento significativo en el número de casos de COVID-19 ni de brotes o recaídas durante el periodo de confinamiento. En términos económicos, los pacientes con EM españoles sufrieron un impacto negativo significativamente menor que los cubanos y chinos. Todos los pacientes usaron plataformas digitales o redes sociales con más frecuencia, probablemente con el fin de mantener relaciones personales. Los pacientes chinos y cubanos mostraron mayor confianza en el control de la pandemia que los españoles, que resultaron ser más pesimistas.

Overnight switch from levetiracetam to brivaracetam. Safety and tolerability.

Brivaracetam is a newer antiseizure medication than levetiracetam. It has a more selective action on the synaptic vesicle glycoprotein 2A binding site, and it seems to provide a more favorable neuropsychiatric profile. The aim of this study was to assess the safety and tolerability of an overnight switch from levetiracetam to brivaracetam. This was a retrospective descriptive study including patients with epilepsy treated with levetiracetam, who switched due to inefficacy or previous adverse events (AEs). In total, forty-one patients were included (mean age 40.9 ± 17.8 years, women 48.8%). Focal epilepsy represented 75.6% (n = 31) of patients (structural cause [n = 25], unknown cause [n = 6]). Four patients had idiopathic generalized epilepsy, two had developmental and epileptic encephalopathy and four patients were unclassified. The reason to start brivaracetam was inefficacy in 53.7% (n = 22), AEs in 65.9% (25/27 neuropsychiatric) and both in 19.5% (n = 8). Brivaracetam-related AEs were reported in 24.4%. Neuropsychological AEs associated with the previous use of levetiracetam improved in 76% of patients. Treatment was discontinued in 19.5% patients. Patients' reported seizure frequency improved, worsened and remained stable in 26.8%, 12.2%, and 61.0% of the cases, respectively. An overnight switching to brivaracetam is safe and well tolerated. This treatment can improve levetiracetam-related neuropsychiatric AEs.

[Response to perampanel in a patient with chronic post-hypoxic myoclonus]. / Respuesta a perampanel en un paciente con mioclono posthipóxico crónico.

INTRODUCTION: Chronic post-hypoxic myoclonus is a condition in which the predominant clinical picture is myoclonus following hypoxic brain damage, usually due to cardiorespiratory arrest. It is a condition that is usually treated with antiepileptic drugs, in most cases with a modest clinical response. CASE REPORT: We report the case of a patient who started with jerking movements, compatible with myoclonus in the four limbs and the face the day after recovering from a cardiorespiratory arrest. An electroencephalogram was performed during which the myoclonias were recorded with no electrical correlates. During admission, and in successive visits after discharge, different antiepileptic treatments were tried for the myoclonias, which were refractory and affected the patient's quality of life. Two years after onset, treatment with perampanel up to a dose of 4 mg was initiated and the patient reported a significant clinical improvement, as evidenced in the visits. CONCLUSIONS: Perampanel may be an effective alternative for the treatment of myoclonias in patients with chronic post-hypoxic myoclonus.

TITLE: Respuesta a perampanel en un paciente con mioclono posthipóxico crónico.Introducción. El mioclono posthipóxico crónico es un cuadro cuya clínica predominante son las mioclonías que acontecen tras un daño cerebral hipóxico, generalmente por parada cardiorrespiratoria. Es una entidad que se trata generalmente con fármacos antiepilépticos, con una modesta respuesta clínica en la mayoría de los casos. Caso clínico. Paciente que comienza con movimientos de sacudidas, compatibles con mioclonías de las cuatro extremidades y faciales al día siguiente de una parada cardiorrespiratoria recuperada. Se realizó un electroencefalograma durante el cual se registraron las mioclonías sin presentar correlato eléctrico. Durante el ingreso, y en sucesivas visitas tras el alta, se probaron diferentes tratamientos antiepilépticos para las mioclonías, que fueron refractarias y comportaron una afectación de la calidad de vida del paciente. Tras dos años de evolución, se inició tratamiento con perampanel hasta una dosis de 4 mg y el paciente refirió una mejoría clínica importante, evidenciada en consultas. Conclusiones. El perampanel puede suponer una alternativa eficaz para el tratamiento de las mioclonías en pacientes con mioclono posthipóxico crónico.

Supported Biofilms on Carbon-Oxide Composites for Nitrate Reduction in Agricultural Waste Water.

Escherichia coli colonies were grown on different supports for the removal of nitrates from water. A carbon material and different commercial metal oxides, such as SiO2, TiO2 and Al2O3, and their corresponding carbon-metal oxide composites were studied. The physicochemical properties were analyzed by different techniques and the results were correlated with their performance in the denitrification process. Developed biofilms effectively adhere to the supports and always reach the complete reduction of nitrates to gaseous products. Nevertheless, faster processes occur when the biofilm is supported on mesoporous and non-acid materials (carbon and silica).

Sequence subtyping of Trichomonas gallinae from Bonelli's eagle (Aquila fasciata) during four years (2014-2017) reveals that MLS type is associated with lesions.

Avian trichomonosis is a parasitic disease that affects wild birds. The objective of this work was to determine the importance of avian trichomonosis in Bonelli's eagles to improve conservation measures in this population. One hundred and eighty-eight birds were studied: 181 chicks, two juveniles, one subadult and four adults. The birds were externally examined and gross lesions at the oropharynx registered. Samples from the oropharyngeal cavity were obtained for Trichomonas spp. detection by culture and PCR, and positive samples were subjected to a multilocus sequence typing approach, including the ITS1/5.8S/ITS2 region (ITS), ribosomal RNA small subunit (18S) and Fe-hydrogenase gene (FeHyd). Global prevalence of T. gallinae infection was 37.8% in total, 45.5% in nestlings. Thirty-three percent of the birds developed lesions that ranged from mild (n = 41) to moderate (n = 14) or severe (n = 7). Multilocus sequence typing analysis showed five different MLS types, ITS-A/18S-VI/FeHyd-A1 and ITS-D/18S-II/Fe-C4 being the most frequent. An association between ITS-A/18S-VI/FeHyd-A1 and moderate or severe lesions was observed, but birds with type ITS-A/18S-VI/FeHyd-A2 also developed lesions. On the contrary, birds with MLS type ITS-D/18S-II/FeHyd-C4 displayed only a low proportion of mild lesions. Chicks raised in nests were at higher risk for T. gallinae infection and development of lesions than chicks raised in captivity. Discordances between samples cultured in TYM and samples subjected to PCR from oropharyngeal swabs were observed, swab-ITS-PCR being more sensitive.RESEARCH HIGHLIGHTS 45.5% of Bonelli's eagles in the nest carried T. gallinae and 39.4% showed lesions.PCR from oral swabs showed higher sensitivity than culture in TYM for detection of T. gallinae.MLS types ITS-A/18S-VI/Fe-A1 (and A2) are a risk factor for the development of lesions.

Enfoque organizativo y clínico de la osteoporosis en reumatología: encuesta y consenso OP-SER-Excellence / Organisational and Clinical Approach to Osteoporosis in Rheumatology: OP-SER-Excellence Survey and Consensus

Introducción: Los estudios de opinión sobre la percepción del reumatólogo de la práctica asistencial en osteoporosis (OP) pueden ayudar a identificar áreas de mejora en la gestión de esta patología. Objetivo: Conocer y analizar el enfoque organizativo que adoptan los reumatólogos españoles ante la OP para definir prioridades estratégicas y establecer unos estándares de calidad. Material y método: Un grupo de expertos diseñó una encuesta sobre creencias y conductas en OP en la práctica del reumatólogo. La encuesta se remitió a los socios de la Sociedad Española de Reumatología (SER). Mediante ronda Delphi se consensuaron las prioridades estratégicas en OP. Resultados: El grupo de expertos consensuó como prioridades estratégicas en OP: 1) La SER debería impulsar la inclusión de la OP en el conjunto de prestaciones de todos los servicios de reumatología, así como ampliar la oferta formativa específica para médicos y enfermeras; 2) Los servicios de reumatología debieran fomentar el papel de la enfermera en OP, impulsar la implantación y el seguimiento de indicadores de calidad e implantar protocolos de derivación consensuados con atención primaria además de impulsar su formación en esta área; 3) La SER y los servicios de reumatología deberían impulsar la implantación de la consulta electrónica y la consulta monográfica o dedicada a OP así como la participación del reumatólogo en unidades de fractura, Fracture Liaison Service. Conclusiones: Las prioridades estratégicas en OP derivadas de la encuesta a los reumatólogos españoles ayudan a identificar las áreas de mejora a nivel organizativo, estructural y de estándares de calidad en esta patología.(AU)

Objective: To determine and analyse the organisational approach adopted by Spanish rheumatologists to osteoporosis (OP) to define strategic priorities. Material and method: A group of experts designed a questionnaire on OP in the rheumatologist practice. The survey was sent to the Spanish Society of Rheumatology (SER) members. Through the Delphi round, strategic priorities were agreed upon in OP. Results: The priorities are: 1) The SER should promote the inclusion of OP in 100% of the services and expand the training offer; 2) Rheumatology services should promote the role of the nurse in OP, promote quality indicators and referral protocols agreed with primary care in addition to promoting their training in this area; 3) The SER and Rheumatology services should promote electronic consultation, OP monographic clinics and participation in Fracture Liaison Service units. Conclusions: Strategic priorities in OP help identify areas of improvement at organisational, structural and quality standards level in this pathology.(AU)

Status epilepticus without impairment of consciousness: Long-term outcomes according to duration.

OBJECTIVE: The point after which non-convulsive status epilepticus (NCSE) can cause permanent damage remains to be elucidated. The aim of this study was to analyze the association between time to resolution and long-term outcomes in NCSE. METHODS: We performed a retrospective study of all patients with focal NCSE without consciousness impairment at two tertiary care hospitals in Spain. All the data were registered prospectively and the study period was December 2014-May 2018. We collected information on demographics, SE etiology, time to administration of different lines of treatment, time to NCSE resolution, and outcomes at discharge, 1 year, and 4 years. Clinical outcome was prospectively categorized as good (return to baseline function) or poor (new disability and death). RESULTS: Seventy-four patients with a mean (±SD) age of 63.4 ±â€¯17.5 years and a mean follow-up time of 2.4 ±â€¯2.2 years were studied. A poor outcome at discharge was associated with a potentially fatal etiology (p < 0.001), EMSE score (Epidemiology-based Mortality Score in Status Epilepticus) (p = 0.012), lateral periodic discharges on EEG (p = 0.034), and occurrence of major complications during hospitalization (p = 0.007). An SE duration of >100 h was clearly associated with a worse outcome (p < 0.001). In the multiple regression analysis, the only independent predictors of a poor outcome at discharge were an SE duration of >+100 hours (p = 0.001), a potentially fatal etiology (p = 0.001), and complications during hospitalization (p = 0.010). An SE duration of >100 hours retained its value as the optimal cutoff point for predicting poor outcomes at both 1 year (p = 0.037) and 4 years (p = 0.05). Other predictors of poor long-term outcomes were a potentially fatal etiology (p < 0.001) and EMSE score (p = 0.034) at 1 year, and progressive symptomatic etiology at 4 years (p = 0.025). SIGNIFICANCE: In patients with focal NCSE without consciousness impairment, a potentially fatal etiology and an SE duration of >100 h were associated with poor short-term and long-term outcomes.

Study of the Tagus River and Entrepeñas reservoir ecosystem around the Trillo nuclear power plant using chemometric analysis: Influence on water, sediments, algae and fish.

The fluvial and aquatic ecosystem of the Tagus River and Entrepeñas reservoir located in the surrounding of the Trillo nuclear power plant (NPP) was evaluated from 1992 to 2008, considering the physical-chemical characteristics, metal content and radiological activity of the water, sediments, algae and fish. The water of both basins demonstrated pH, conductivity, COD, NO3- and DO values within a range considered as good quality and the water quality index (WQI) was found to be within a range of 71-90. Chemometric analysis revealed a shift in the river water (from upstream to downstream) affected by the concentration of salts and metals of natural origin, such as Fe and Al, and slight variations in temperature and radiological activity were detected due to the discharges from the NPP. The hydric conditions contributed to increase or decrease the metal concentration of the river water, the reservoir sediments, algae and fish. Fe and Al were found in higher concentration during drought periods and accumulated in sediments, algae and fish along the river course (from SP1 to SP3). Natural and artificial radionuclides found were 40K with an average of 245 Bq/kg in river sediments, 499 Bq/kg in reservoir sediments and 121 Bq/kg in fish, and 90Sr with a concentration between 0.40 and 1.30 Bq/kg in sediments. Contamination of the aquatic ecosystem with metals and radionuclides was low according to European legislation. In conclusion, this study provides additional elements aimed at understanding the dynamics of fluvial and lentic ecosystems under the influence of different disturbances.

Implications of initiating antiseizure drugs prior to the performance of EEG in first epileptic seizures. / Implicaciones de iniciar fármacos antiepilépticos previo a la realización de EEG en primeras crisis epilépticas.

INTRODUCTION: This study aimed to determine whether the administration of antiepileptic drugs (AED) alters the likelihood of detecting epileptiform abnormalities in electroencephalographies (EEG) performed early after a first epileptic seizure. METHOD: We performed a retrospective, observational study including patients with a first seizure attended at our centre's emergency department between July 2014 and November 2019. We collected clinical data, as well as technical data on the acquisition and interpretation of the EEG performed within the first 72hours after the seizure, and the factors related with seizure recurrence. RESULTS: We recruited 155 patients with a mean (SD) age of 48.6 (22.5) years; 61.3% were men. Regarding seizure type, 51% presented tonic-clonic seizures of unknown onset and 12% presented focal to bilateral tonic-clonic seizures. Thirty-nine patients (25.2%) received AED treatment before the EEG was performed: 33 received a non-benzodiazepine AED and 6 received a benzodiazepine. Epileptiform abnormalities were observed in 29.7% of patients. Previous administration of AEDs was not significantly associated with the probability of detecting interictal epileptiform abnormalities (P=.25) or with the risk of recurrence within 6 months (P=.63). CONCLUSIONS: Administration of AEDs before an early EEG following a first seizure does not decrease the likelihood of detecting epileptiform abnormalities. These findings suggest that starting AED treatment immediately in patients with a high risk of early recurrence does not imply a reduction in the diagnostic accuracy of the test.

Validation of a combined ELISA to detect IgG, IgA and IgM antibody responses to SARS-CoV-2 in mild or moderate non-hospitalised patients.

BACKGROUND: Frequently SARS-CoV-2 results in mild or moderate disease with potentially lower concentrations of antibodies compared to those that are hospitalised. Here, we validated an ELISA using SARS-CoV-2 trimeric spike glycoprotein, with targeted detection of IgG, IgA and IgM (IgGAM) using serum and dried blood spots (DBS) from adults with mild or moderate disease. METHODS: Targeting the SARS-CoV-2 trimeric spike, a combined anti-IgG, IgA and IgM serology ELISA assay was developed using 62 PCR-confirmed non-hospitalised, mild or moderate COVID-19 samples, ≥14 days post symptom onset and 624 COVID-19 negative samples. The assay was validated using 73 PCR-confirmed non-hospitalised, mild or moderate COVID-19 samples, ≥14 days post symptom onset and 359 COVID-19 negative serum samples with an additional 81 DBSs. The assay was further validated in 226 PCR-confirmed non-hospitalised, mild or moderate COVID-19 samples, ≥14 days post symptom onset and 426 COVID-19 negative clinical samples. RESULTS: A sensitivity and specificity of 98.6% (95% CI, 92.6-100.0), 98.3% (95% CI, 96.4-99.4), respectively, was observed following validation of the SARS-CoV-2 ELISA. No cross-reactivities with endemic coronaviruses or other human viruses were observed, and no change in results were recorded for interfering substances. The assay was stable at temperature extremes and components were stable for 15 days once opened. A matrix comparison showed DBS to correlate with serum results. Clinical validation of the assay reported a sensitivity of 94.7% (95% CI, 90.9-97.2%) and a specificity of 98.4% (95% CI, 96.6-99.3%). CONCLUSIONS: The human anti-IgGAM SARS-CoV-2 ELISA provides accurate and sensitive detection of SARS-CoV-2 antibodies in non-hospitalised adults with mild or moderate disease. The use of dried blood spots makes the assay accessible to the wider community.

Knowledge acquired from Clinical Guidelines on the Diagnosis and Treatment of Acute Pancreatitis by attending physicians and residents in hospitals in Veracruz. / Conocimiento de las Guías Clínicas de Diagnóstico y Tratamiento de la Pancreatitis Aguda en médicos adscritos y residentes de los hospitales de Veracruz.

INTRODUCTION: Clinical practice guidelines on the diagnosis and treatment of acute pancreatitis (CPGDTAP) have been designed in an effort to reduce the morbidity and mortality of that severe disease. AIM: To identify the knowledge acquired from CPGDTAP in hospitals in Veracruz. MATERIALS AND METHODS: A descriptive, observational, multicenter study was conducted at four hospitals in Veracruz, through the application of a survey to evaluate the knowledge of attending physicians and residents that treat patients with acute pancreatitis. Descriptive statistics were employed to analyze the results. RESULTS: A total of 74 physicians were surveyed: 55.41% of whom were attending physicians and 44.59% of whom were resident physicians. The majority of physicians (67.57%) were familiar with CPGDTAP from the Asociación Mexicana de Gastroenterología (AMG), followed by those of the General Health Council of the Mexican Department of Health (CENETEC, the Spanish acronym) (54.05%) and the American College of Gastroenterology (ACG) (48.65%). A total of 97.30% of the physicians routinely use a nasogastric tube, 79.73% considered early enteral nutrition to be very important, as did 98.65% regarding generous fluid replacement, 85.14% did not routinely use antimicrobials, 63.51% ordered a CAT scan at 72h or later, and 87.84% answered that infected necrosis was the indication for surgery, preferably after the third week. DISCUSSION AND CONCLUSIONS: In our hospital environment, the CPGDTAP issued by the AMG and CENETEC were the most well-known, but their recommended measures were given importance by under 85% of the physicians surveyed. Therefore, the diffusion of the knowledge they contain is advisable to guarantee optimal results in acute pancreatitis management.
