Nutrient dynamics in wetland systems associated with hydrological and anthropogenic variations in the south of Samborombón Bay, Argentina.

Wetlands provide numerous ecosystem services to the environment, such as nutrient removal and storage. The aim of this work is to evaluate the nutrient dynamics in different sectors within wetland systems in the south of the Samborombón Bay (Argentina) based on hydrological and/or anthropogenic variations. For this purpose, the hydrological features of the wetland were defined through the analysis of satellite images, precipitation and tidal data, and field surveys. Three sectors were identified in the wetland: one with tidal influence, another which is dependent on rainfall, and another that receives inputs from rainfall and from a sewage effluent treatment plant. In order to analyze the nutrient dynamics, samples of surface water, groundwater, and sediments were collected from these sectors. Measurements of pH and electrical conductivity were determined in situ in water samples, while the concentration of inorganic forms of phosphorus and nitrogen, soluble reactive silica, and organic carbon were determined through laboratory analysis. Also, bioavailable phosphorus, organic matter, pH, and electrical conductivity were determined in the sediment samples collected. Statistical analysis of the data reveals differences between the sectors and allows the interpretation of the dynamics of the studied components in the wetland. Electrical conductivity distinguishes the intertidal sectors of the wetland while components associated with P and N discriminate the sectors with inputs from the sewage effluent treatment plant. On the other hand, soluble reactive silica, organic carbon, and organic matter do not seem to be influenced by the tide or effluent discharge. This study demonstrates that the studied wetland works as a nutrient retention area, providing ecosystem services to local inhabitants. Although these services can be utilized, they require a continuous monitoring over time to provide an early warning in case the variations in P and N cycles could lead to eutrophication or wetland degradation.

Manejo de la trombosis venosa cerebral en España: estudio descriptivo MOTIVATE / Management of cerebral venous thrombosis in Spain: MOTIVATE descriptive study

Introducción: La trombosis venosa cerebral (TVC) es una causa poco común de ictus que afecta principalmente a adultos jóvenes. Un diagnóstico precoz y preciso puede reducir la tasa y gravedad de las complicaciones. Objetivo: Analizar las características clínicas, manejo y tratamiento de la TVC en diferentes centros de nuestro país. Métodos: Estudio descriptivo retrospectivo multicéntrico de pacientes hospitalizados por TVC entre 2008 y 2017 en 11 centros sanitarios en nuestro país. Resultados: Se incluyeron 256 pacientes, edad media 49,8 ± 18,7 años y el 51% fueron mujeres. Los síntomas más frecuentes fueron: cefalea (73%), déficits focales (50%), crisis epilépticas (33%) y encefalopatía (21%). Las localizaciones más frecuentes fueron: seno longitudinal superior (12,5%), transverso (10,9%) y afectación de dos o más senos o venas (66,4%). La etiología conocida más frecuente fue la trombofilia (24%), siendo la mutación de la protrombina G20210A la más común (19%). El 46% fue tratado con antitrombóticos durante 3-6 meses, el 21% durante un año y un 22,6% de los pacientes requirieron anticoagulación indefinida. En un 5% de los sujetos fue preciso terapia endovascular y un 33% requirió neurocirugía. En relación al pronóstico, el 75% fueron independientes a los 3 meses con una puntuación en la escala de Rankin modificada (mRS) ≤ 2 y la presencia de papiledema (p = 0,03), déficit focal (p = 0,001) y encefalopatía (p < 0,001) se relacionaron significativamente con mal pronóstico (mRS > 3). La tasa de mortalidad intrahospitalaria fue del 4,3% y el 6,3% de los pacientes fallecieron a los 3 meses. Conclusión:La diversidad de factores de riesgo y la presentación variable suponen un desafío en el diagnóstico y tratamiento de la TVC. Para mejorar el pronóstico y reducir la mortalidad es fundamental la instauración de protocolos en el manejo de esta patología.(AU)

Introduction: Cerebral venous thrombosis (CVT) is an uncommon cause of stroke that mainly affects young adults. Early, accurate diagnosis can reduce the rate and severity of complications. Objective: The aim of this study was to analyse the clinical characteristics, management, and treatment of CVT in different centres in Spain. Methods: We conducted a multicentre, retrospective, descriptive study of patients hospitalised due to CVT between 2008 and 2017 at 11 Spanish centres. Results: We included 256 patients, with a mean age (SD) of 49.8 (18.7) years; 51% of patients were women. The most frequent symptoms were headache (73%), focal deficits (50%), epileptic seizures (33%), and encephalopathy (21%). The most frequent localisations were the superior sagittal sinus (12.5%), the transverse sinus (10.9%), and 2 or more sinuses or veins (66.4%). Thrombophilia was the most frequent known aetiology (24%), and was most commonly associated with the prothrombin G20210A mutation (19%). Forty-six percent of patients were treated with antithrombotics for 3-6 months, 21% for one year, and 22.6% required indefinite anticoagulation. Endovascular therapy was performed in 5% of cases, and 33% required neurosurgery. Regarding outcomes, 75% of patients were independent at 3 months (modified Rankin Scale [mRS] score ≤ 2), with papilloedema (P = .03), focal deficits (P = .001), and encephalopathy (P < .001) showing a statistically significant association with poor prognosis (mRS > 3). The in-hospital mortality rate was 4.3%, with a 3-month mortality rate of 6.3%. Conclusion: The diverse risk factors and variable presentation of CVT represent a challenge in the diagnosis and treatment of this condition. To improve prognosis and reduce mortality, it is essential to establish management protocols for this entity.(AU)

Selection of patients for percutaneous closure in nonlacunar cryptogenic stroke associated with patent foramen ovale. Data from the NORDICTUS cooperative registry.

INTRODUCTION: There is an extending use of percutaneous closure of patent foramen ovale (PFO) as therapy for PFO-associated cryptogenic strokes. The aim of our study was to investigate the clinical practice of percutaneous closure of PFO and to analyse the variables for decision-making on the selection of patients for this procedure. METHOD: A prospective observational multicentric survey was conducted using all the cases of cryptogenic stroke/transient ischaemic attack associated with PFO recorded in the NORDICTUS hospital registry during the period 2018-2021. Clinical data, radiological patterns, echocardiogram data and factors related to PFO-associated stroke (thromboembolic disease and paradoxical embolism criteria) were recorded. The indication for closure was analysed according to age (≤/> 60 years) and the characteristics of the PFO. RESULTS: In the group ≤ 60 years (n = 488), 143 patients (29.3%) underwent PFO closure. The most influential variables for this therapy were detection of a high-risk PFO (OR 4.11; IC 2.6-6.5, P < .001), criteria for paradoxical embolism (OR 2.61; IC 1.28-5.28; P = .008) and previous use of antithrombotics (OR 2.67; IC 1.38-5.18; P = .009). In the > 60 years group (n = 124), 24 patients had PFO closure (19%). The variables related to this option were history of pulmonary thromboembolism, predisposition to thromboembolic disease, paradoxical embolism criteria, and high-risk PFO. CONCLUSIONS: The detection of a high-risk PFO (large shunt, shunt with associated aneurysm) is the main criterion for a percutaneous closure-based therapy. Other conditions to consider in the eligibility of patients are the history of thromboembolic disease, paradoxical embolism criteria or the previous use of antithrombotics.

[Prognosis of patients assisted in the emergency unit by the 'TIA protocol' in a third-level hospital at 90 days]. / Pronóstico de pacientes atendidos en urgencias mediante 'protocolo AIT' en un hospital de tercer nivel a los 90 días.

INTRODUCTION: Care models developed for the rapid management of patients with transient ischaemic attack (TIA) are safe, effective and reduce recurrence rates. The aim is to determine the prevalence of cardiovascular events at 90 days. PATIENTS AND METHODS: An observational, analytical, cross-sectional study was conducted. Adult male and female patients seen in the emergency department using the 'TIA protocol' between January 2016 and December 2019 were analysed. Data were collected on clinical variables, complementary tests, treatment and cardiovascular events (stroke/TIA, acute coronary syndrome or death due to cardiovascular causes) at 90 days. The study was approved by the Research Ethics Committee of Aragon. RESULTS: The TIA protocol was performed on 163 out of 591 patients diagnosed with TIA in the emergency department. Brain CT and neurosonology scans were performed in 100% and a 24-hour Holter-electrocardiogram was carried out in 52.1%; atrial fibrillation (AF) was detected in 3.6% of them. An MRI brain scan was performed in 78.4% and acute ischaemic injury was seen in diffusion sequences (DWI+) in 13.5%. The prevalence of cardiovascular events at 90 days was 4.9% (8): stroke, 3.1% (five TIAs); acute coronary syndrome, 0.6% (one); and death from cardiovascular causes, 1.2% (two). Major adverse cardiovascular events were significantly associated with a history of ischaemic heart disease (p = 0.014). Cardiovascular death was associated with a history of AF (p = 0.008), anticoagulants at discharge (p = 0.007) and no antiplatelet therapy at discharge (p = 0.012), and there was a tendency towards an association with a history of type 2 diabetes mellitus (p = 0.05). CONCLUSIONS: Rapid TIA protocols allow early care and avoid hospital admissions, without increasing the incidence of cardiovascular events or recurrence of stroke or TIA at 90 days.

Los eventos adversos cardiovasculares mayores se asociaron de forma significativa al antecedente de cardiopatía isquémica (p = 0,014). La muerte por causa cardiovascular se asoció al antecedente de FA (p = 0,008), anticoagulación al alta (p = 0,007) y no antiagregación al alta (p = 0,012), y hubo una tendencia a la asociación con antecedente de diabetes mellitus de tipo 2 (p = 0,05). Conclusiones. Los protocolos AIT de actuación rápida permiten una atención precoz y evitan ingresos hospitalarios, sin implicar un incremento en la incidencia de eventos cardiovasculares o recurrencia de ictus o AIT a los 90 días.

Introduction: The COVID-19 pandemic has had an impact on ischaemic stroke management, with a reported decrease in hospital admissions, and even disruptions in healthcare and increased in-hospital mortality. However, there is a lack of evidence on the impact of the pandemic on functional prognosis. The aim of this study is to analyse the effect of the COVID-19 pandemic on the 3-month functional outcomes of patients hospitalised due to acute ischaemic stroke in Aragon (Spain).Materil and methodsWe reviewed the data of all patients admitted due to ischaemic stroke to any hospital in our regional healthcare system between 30 December 2019 and 3 May 2020. We compared modified Rankin Scale scores and mortality at 3 months in patients hospitalised before and after the declaration of a state of emergency due to the COVID-19 pandemic.ResultsIn total, 318 patients with acute ischaemic stroke met our inclusion criteria. No differences were observed between periods in global or specific characteristics, with the exception of a higher proportion of patients older than 80 years during the first period (42.2% vs. 29.0%, P=.028). In the comparative analysis, we found no significant differences in mortality (12.3 vs. 7.9, P=.465) or in the proportion of patients with modified Rankin Scale scores ≤ 2 (57.7% vs. 57.1%, P=.425) at 3 months.ConclusionTo our knowledge, this is the first study to analyse the impact of COVID-19 pandemic on the 3-month functional outcomes of patients with ischaemic stroke.

[Emergency department management of epileptic seizures in patients with epilepsy]. / Atención en el servicio de urgencias de las crisis epilépticas en pacientes con epilepsia.

AIM: To analyse the care of patients with epilepsy (PwE) who visit the hospital emergency department (ED) due to an epileptic seizure. MATERIALS AND METHODS: Single-centre retrospective observational study, based on the clinical history of the PwE seen in the ED for epileptic seizures between January 2016 and December 2018. Demographic, clinical and ED management variables were collected. Specifically, the results of a computed tomography (CT) brain scan and electroencephalogram and the presence of precipitating factors for epileptic seizures were analysed. RESULTS: A total of 232 PwE were identified, with a mean age of 49.8 years. The most frequent reason for the visit was focal epileptic seizures (50.4%). In 106 cases (45.6%) possible precipitating factors were found, of which poor therapy adherence was the most frequent. An urgent CT brain scan was performed in 67 cases (28.9%) and acute alterations were found in only one patient. An electroencephalogram was carried out in 16 of them (6.9%). Adjustments were made to the antiepileptic treatment in 135 patients (58.1%). A total of 195 were discharged without being hospitalised (84.1%). CONCLUSIONS: PwE accounted for a considerable proportion of the patients seen for epileptic seizures in the ED. The presence of a potentially controllable precipitating factor was identified in almost half of the cases, the most frequent being poor adherence to therapy. In addition, a high number of urgent complementary tests were performed, which in many cases may be unnecessary and avoidable.

Analizar la atención al paciente con epilepsia (PcE) que consulta en el servicio de urgencias hospitalarias (SUH) por una crisis epiléptica. Materiales y métodos. Estudio observacional retrospectivo unicéntrico, basado en la historia clínica de los PcE atendidos en el SUH por crisis epilépticas entre enero de 2016 y diciembre de 2018. Se recogieron variables demográficas, clínicas y de manejo en el SUH. De forma específica, se analizó la realización de una tomografía computarizada cerebral y un electroencefalograma, y la presencia de factores precipitantes de crisis epilépticas. Resultados. Se identificó a 232 PcE, con una edad media de 49,8 años. El motivo de atención más frecuente fueron las crisis epilépticas focales (50,4%). En 106 (45,6%) se encontraron posibles factores precipitantes, de entre los cuales, la mala adhesión terapéutica fue el más frecuente. En 67 casos (28,9%) se realizó una tomografía computarizada cerebral urgente, y se encontraron alteraciones agudas en un solo paciente. En 16 (6,9%) se realizó un electroencefalograma. Se realizó un ajuste del tratamiento antiepiléptico en 135 pacientes (58,1%). Fueron dados de alta sin hospitalización 195 (84,1%). Conclusiones. Los PcE representaron una proporción considerable de pacientes atendidos por crisis epilépticas en el SUH. Casi en la mitad de los casos se identificó la presencia de algún factor precipitante potencialmente controlable, y el más frecuente fue la mala adhesión terapéutica. Además, se observó una realización de pruebas complementarias urgentes elevada, que en muchos casos podrían ser prescindibles.

Three-month functional prognosis of patients hospitalised due to acute ischaemic stroke in Aragon: regional analysis of the impact of COVID-19.

INTRODUCTION: The COVID-19 pandemic has had an impact on ischaemic stroke management, with a reported decrease in hospital admissions, and even disruptions in healthcare and increased in-hospital mortality. However, there is a lack of evidence on the impact of the pandemic on functional prognosis. The aim of this study is to analyse the effect of the COVID-19 pandemic on the 3-month functional outcomes of patients hospitalised due to acute ischaemic stroke in Aragon (Spain). METHODS: We reviewed the data of all patients admitted due to ischaemic stroke to any hospital in our regional healthcare system between 30 December 2019 and 3 May 2020. We compared modified Rankin Scale scores and mortality at 3 months in patients hospitalised before and after the declaration of a state of emergency due to the COVID-19 pandemic. RESULTS: In total, 318 patients with acute ischaemic stroke met our inclusion criteria. No differences were observed between periods in global or specific characteristics, with the exception of a higher proportion of patients older than 80 years during the first period (42.2% vs 29.0%, P = .028). In the comparative analysis, we found no significant differences in mortality (12.3 vs 7.9, P = .465) or in the proportion of patients with modified Rankin Scale scores ≤ 2 (57.7% vs 57.1%, P = .425) at 3 months. CONCLUSION: To our knowledge, this is the first study to analyse the impact of COVID-19 pandemic on the 3-month functional outcomes of patients with ischaemic stroke. In our region, there has been no increase in rates of mortality or disability at 3 months in patients admitted due to ischaemic stroke during the pandemic.
