RESUMO

Current sample preparation strategies for nanomaterials (NMs) analysis in soils by means single particle inductively coupled plasma mass spectrometry have significant constrains in terms of accuracy, sample throughput and applicability (i.e., type of NMs and soils). In this work, strengths and weakness of microwave assisted extraction (MAE) for NMs characterization in soils were systematically investigated. To this end, different extractants were tested (ultrapure water; NaOH, NH4OH, sodium citrate and tetrasodium pyrophosphate) and MAE operating conditions were optimized by means of design of experiments. Next, the developed method was applied to different type of metallic(oid) nanoparticles (Se-, Ag-, Pt- and AuNPs) and soils (alkaline, acid, sandy, clayey, SL36, loam ERMCC141; sludge amended ERM483). Results show that Pt- and AuNPs are preserved and quantitatively extracted from soils in 6 min (12 cycles of 30 s each) inside an 800 W oven by using 20 mL of 0.1 M NaOH solution. This methodology is applicable to soils showing a wide range of physicochemical properties except for clay rich samples. If clay soil fraction is significant (>15%), NMs are efficiently retained in the soil thus giving rise to poor recoveries (<10%). The analysis of labile NMs such as Se- and AgNPs is not feasible by means this approach since extraction conditions favors dissolution. Finally, when compared to current extraction methodologies (e.g., ultrasound, cloud point extraction, etc.), MAE affords better or equivalent accuracies and precision as well as higher sample throughput due to treatment speed and the possibility to work with several samples simultaneously.

RESUMO

A spatially specific fMRI acquisition requires specificity to the microvasculature that serves active neuronal sites. Macrovascular contributions will reduce the microvascular specificity but can be reduced by using spin echo (SE) sequences that use a π pulse to refocus static field inhomogeneities near large veins. The microvascular specificity of a SE-echo planar imaging (SE-EPI) scan depends on the echo train length (ETL)-duration, but the dependence is not well-characterized in humans at 7T. To determine how microvascular-specific SE-EPI BOLD is in humans at 7T, we developed a Monte Carlo voxel model that computes the signal of a proton ensemble residing in a vasculature subjected to a SE-EPI pulse sequence. We characterized the ETL-duration dependence of the microvascular specificity by simulating the BOLD signal as a function of ETL, the range adhering to experimentally realistic readouts. We performed a validation experiment for our simulation observations, in which we acquired a set of SE-EPI BOLD time series with varying ETL during a hyperoxic gas challenge. Both our simulations and measurements show an increase in macrovascular contamination as a function of ETL, with an increase of 30% according to our simulation and 60% according to our validation experiment between the shortest and longest ETL durations (23.1 - 49.7 ms). We conclude that the microvascular specificity decreases heavily with increasing ETL-durations. We recommend reducing the ETL-duration as much as possible to minimize macrovascular contamination in SE-EPI BOLD experiments. We additionally recommend scanning at high resolutions to minimize partial volume effects with CSF. CSF voxels show a large BOLD response, which can be attributed to both the presence of large veins (high blood volume) and molecular oxygen-induced T1-shortening (significant in a hyperoxia experiment). The magnified BOLD signal in a GM-CSF partial volume voxel reduces the desired microvascular specificity and, therefore, will hinder the interpretation of functional MRI activation patterns.

RESUMO

INTRODUCTION: Glycaemic variability (GV) refers to variations in blood glucose levels, and may affect stroke outcomes. This study aims to assess the effect of GV on acute ischaemic stroke progression. METHODS: We performed an exploratory analysis of the multicentre, prospective, observational GLIAS-II study. Capillary glucose levels were measured every 4 hours during the first 48 hours after stroke, and GV was defined as the standard deviation of the mean glucose values. The primary outcomes were mortality and death or dependency at 3 months. Secondary outcomes were in-hospital complications, stroke recurrence, and the impact of the route of insulin administration on GV. RESULTS: A total of 213 patients were included. Higher GV values were observed in patients who died (n = 16; 7.8%; 30.9 mg/dL vs 23.3 mg/dL; p = 0.05). In a logistic regression analysis adjusted for age and comorbidity, both GV (OR = 1.03; 95% CI, 1.003-1.06; p = 0.03) and stroke severity (OR = 1.12; 95% CI, 1.04-1.2; p = 0.004) were independently associated with mortality at 3 months. No association was found between GV and the other outcomes. Patients receiving subcutaneous insulin showed higher GV than those treated with intravenous insulin (38.95 mg/dL vs 21.34 mg/dL; p < 0.001). CONCLUSIONS: High GV values during the first 48 hours after ischaemic stroke were independently associated with mortality. Subcutaneous insulin may be associated with higher VG levels than intravenous administration.

RESUMO

INTRODUCTION: Ischaemic stroke (IS) due to cervical and cerebral artery dissection (CAD) is a rare entity, and few data are available on the use of such reperfusion therapies as intravenous fibrinolysis and mechanical thrombectomy in these patients. We analysed the use of these treatments in patients with IS due to CAD and compared them against patients receiving reperfusion treatment for IS of other aetiologies. METHODS: We conducted an observational, retrospective, multicentre study of patients with IS due to CAD recorded in the National Stroke Registry of the Spanish Society of Neurology during the period 2011-2019. Comparative analyses were performed between: a) patients with CAD treated and not treated with reperfusion therapies and b) patients treated with reperfusion for IS due to CAD and patients treated with reperfusion for IS due to other causes. Epidemiological data, stroke variables, and outcomes at discharge and at 3 months were included in the analysis. RESULTS: The study included 21,037 patients with IS: 223 (1%) had IS due to CAD, of whom 68 (30%) received reperfusion treatment. Reperfusion treatments were used less frequently in cases of vertebral artery dissection and more frequently in patients with carotid artery occlusion. Compared to patients with IS due to other causes, patients with CAD were younger, more frequently underwent mechanical thrombectomy, and less frequently received intravenous fibrinolysis. Rates of haemorrhagic complications, mortality, and independence at 3 months were similar in both groups. CONCLUSIONS: Reperfusion therapy is frequently used in patients with IS due to CAD. The outcomes of these patients demonstrate the efficacy and safety of reperfusion treatments, and are comparable to the outcomes of patients with IS due to other aetiologies.

RESUMO

Body condition and reproduction data are broadly used to assess the health status of fish because of its implications for recruitment and ecosystem structure. Sardina pilchardus is a small pelagic distributed throughout both Mediterranean and Eastern Atlantic. Seasonal trend analysis of energy storage and reproduction was carried out in sardines from two areas along the Atlantic-Mediterranean transition: Southern Portugal-Gulf of Cádiz (POR-GC) (Atlantic Ocean) and Alboran Sea (Alb) (Mediterranean Sea) from 2019 to 2021. Energetic condition was estimated using tissue and mesenteric fat content, hepatosomatic index (HSI), and the relative condition factor (Kn). Sex, reproductive developmental stage, and gonadosomatic index (GSI) were also obtained. In addition, the oceanographic and meteorological characteristics of the areas were analysed. Results showed that seasonal Kn, tissue and mesenteric fat content, and HSI values of POR-GC specimens exceeded Alb's with summer arrival, period in which sardine acquires reserves to allocate them to reproduction. These differences could be associated to greater productivity of the former area mainly due to rivers discharges and trade winds intensification during summer (from July to September). Furthermore, gonad maturation of POR-GC stock occurred before the Alb. However, no spawning capable individuals were identified until February in POR-GC. In contrast, in Alb it was observed a remarkable fraction of spawning capable and active spawner individuals in October. We hypothesized the migration of mature individuals from POR-GC to the spawning areas located in the Alb. Seasonal genetic population studies are required to untangle it and reliably evaluate the environmental effect on the stocks.

RESUMO

OBJECTIVE: This study aimed to assess individual preference, symptoms and compliance between habitual use of Provox XtraFlow and the combination of Provox XtraFlow during the day and Provox Luna during the night for heat and moisture exchanger therapy in laryngectomised patients. METHOD: This was an open, randomised, crossover trial for 25 days. After this first study period and a 5-day wash-out period, treatments were switched for another 25 days. RESULTS: A total of 28 patients were enrolled. Differences were found (p = 0.009) in the incidence of dermatological problems with XtraFlow (46.4 per cent) versus Provox Luna (14.3 per cent), as well as in the need to abandon the use of adhesives (46.4 per cent vs 10.7 per cent; p = 0.003). A total of 60.7 per cent of the patients preferred the Provox Luna system as their preference for heat and moisture exchanger therapy. CONCLUSION: The Provox Luna system is a viable additive to heat and moisture exchanger therapy, especially in the setting of compliance concerns and in patients who desire dermatological relief overnight.

RESUMO

OBJECTIVE: We present an update of the Spanish Society of Neurology's recommendations for prevention of both primary and secondary stroke in patients with dyslipidaemia. DEVELOPMENT: We performed a systematic review to evaluate the main aspects of the management of dyslipidaemias in primary and secondary stroke prevention and establish a series of recommendations. CONCLUSIONS: In primary prevention, the patient's vascular risk should be determined in order to define target values for low-density lipoprotein cholesterol. In secondary prevention after an atherothrombotic stroke, a target value <55 mg/dL is recommended; in non-atherothombotic ischaemic strokes, given the unclear relationship with dyslipidaemia, target value should be established according to the vascular risk group of each patient. In both primary and secondary prevention, statins are the drugs of first choice, and ezetimibe and/or PCSK9 inhibitors may be added in patients not achieving the target value.

RESUMO

Objetivo: Actualizar las recomendaciones de la Sociedad Española de Neurología para la prevención del ictus, tanto primaria como secundaria, en pacientes con dislipidemia. Desarrollo: Se ha realizado una revisión sistemática en Pubmed evaluando los principales aspectos relacionados con el manejo de las dislipidemias en la prevención primaria y secundaria del ictus, elaborándose una serie de recomendaciones relacionadas con los mismos. Conclusiones: En prevención primaria se recomienda determinar el riesgo vascular del paciente con el fin de definir los objetivos de LDLc. En prevención secundaria tras un ictus de origen aterotrombótico se recomienda un objetivo de LDLc < 55 mg/dl, mientras que en ictus isquémicos de origen no aterotrombótico, dado que su relación con dislipidemias es incierta, se establecerán los objetivos en función del grupo de riesgo vascular de cada paciente. Tanto en prevención primaria como secundaria las estatinas son los fármacos de primera elección, pudiendo asociarse ezetimiba y/o inhibidores de PCSK9 en aquellos casos que no alcancen los objetivos terapéuticos.

RESUMO

OBJECTIVE: To update the recommendations of the Spanish Society of Neurology regarding lifestyle interventions for stroke prevention. DEVELOPMENT: We reviewed the most recent studies related to lifestyle and stroke risk, including randomised clinical trials, population studies, and meta-analyses. The risk of stroke associated with such lifestyle habits as smoking, alcohol consumption, stress, diet, obesity, and sedentary lifestyles was analysed, and the potential benefits for stroke prevention of modifying these habits were reviewed. We also reviewed stroke risk associated with exposure to air pollution. Based on the results obtained, we drafted recommendations addressing each of the lifestyle habits analysed. CONCLUSIONS: Lifestyle modification constitutes a cornerstone in the primary and secondary prevention of stroke. Abstinence or cessation of smoking, cessation of excessive alcohol consumption, avoidance of exposure to chronic stress, avoidance of overweight or obesity, a Mediterranean diet supplemented with olive oil and nuts, and regular exercise are essential measures in reducing the risk of stroke. We also recommend implementing policies to reduce air pollution.

RESUMO

Objetivo: Actualizar las recomendaciones de la Sociedad Española de Neurología para la prevención de ictus, tanto primaria como secundaria, en pacientes con hipertensión arterial.DesarrolloSe han planteado diferentes preguntas para identificar cuestiones prácticas para el manejo de la presión arterial (PA) en prevención de ictus, analizando cuál debe ser el objetivo de control de la presión arterial y cuáles son los fármacos más adecuados en prevención primaria, cuándo iniciar el tratamiento antihipertensivo después de un ictus, cuáles son las cifras que debemos alcanzar y qué fármacos son los más adecuados en prevención secundaria de ictus. Se ha realizado una revisión sistemática en Pubmed analizando los principales ensayos clínicos para dar respuesta a estas preguntas y se han elaborado unas recomendaciones.ConclusionesEn prevención primaria se recomienda iniciar tratamiento antihipertensivo con cifras de PA > 140/90 mmHg, con un objetivo de control de PA < 130/80 mmHg. En prevención secundaria de ictus se recomienda iniciar tratamiento antihipertensivo pasada la fase aguda (primeras 24 h) con un objetivo de control de PA < 130/80 mmHg, siendo preferible el empleo de ARA-II o diuréticos solos o en combinación con IECA.

Objective: To update the recommendations of the Spanish Society of Neurology on primary and secondary stroke prevention in patients with arterial hypertension.DevelopmentWe proposed several questions to identify practical issues for the management of blood pressure (BP) in stroke prevention, analysing the objectives of blood pressure control, which drugs are most appropriate in primary prevention, when antihypertensive treatment should be started after a stroke, what levels we should aim to achieve, and which drugs are most appropriate in secondary stroke prevention. We conducted a systematic review of the PubMed database and analysed the main clinical trials to address these questions and establish a series of recommendations.ConclusionsIn primary stroke prevention, antihypertensive treatment should be started in patients with BP levels > 140/90 mmHg, with a target BP of < 130/80 mmHg. In secondary stroke prevention, we recommend starting antihypertensive treatment after the acute phase (first 24 hours), with a target BP of < 130/80 mmHg. The use of angiotensin-II receptor antagonists or diuretics alone or in combination with angiotensin-converting enzyme inhibitors is preferable. (AU)

RESUMO

Objetivo: Actualizar las recomendaciones de la Sociedad Española de Neurología relativas a la actuación sobre los hábitos de vida para la prevención del ictus.DesarrolloSe ha realizado una revisión de los estudios más recientes relacionados con los hábitos de vida y el riesgo de ictus, incluyendo ensayos clínicos aleatorizados, estudios poblacionales y metaanálisis. Se ha analizado el riesgo de ictus asociado con determinados hábitos de vida como el tabaquismo, el consumo de alcohol, el estrés, la dieta, la obesidad y el sedentarismo, también se ha revisado el potencial beneficio que la modificación de esos hábitos de vida puede aportar en la prevención del ictus. Asimismo, se ha revisado el riesgo de ictus asociado a la exposición a la contaminación atmosférica. A partir de los resultados obtenidos se han redactado unas recomendaciones sobre cada uno de los hábitos de vida analizados.ConclusionesLa actuación sobre los hábitos de vida constituye una piedra angular en la prevención primaria y secundaria del ictus. La abstinencia o cese del hábito tabáquico, el cese del consumo excesivo de alcohol, evitar la exposición a estrés crónico, evitar el sobrepeso o la obesidad, seguir una dieta mediterránea suplementada con aceite de oliva y frutos secos, así como la práctica regular de actividad física son medidas fundamentales para reducir el riesgo de sufrir un ictus. Además, se aconseja desarrollar políticas encaminadas a disminuir la contaminación atmosférica. (AU)

RESUMO

Gaucher disease (GD) is caused by homozygous mutations in the GBA1 gene, which encodes the lysosomal ß-glucosidase (GBA) enzyme. GD affects several organs and tissues, including the brain in certain variants of the disease. Heterozygous GBA1 variants are a major genetic risk factor for developing Parkinson's disease. The RIPK3 kinase is relevant in GD and its deficiency improves the neurological and visceral symptoms in a murine GD model. RIPK3 mediates necroptotic-like cell death: it is unknown whether the role of RIPK3 in GD is the direct induction of necroptosis or if it has a more indirect function by mediating necrosis-independent. Also, the mechanisms that activate RIPK3 in GD are currently unknown. In this study, we show that c-Abl tyrosine kinase participates upstream of RIPK3 in GD. We found that the active, phosphorylated form of c-Abl is increased in several GD models, including patient's fibroblasts and GBA null mice. Furthermore, its pharmacological inhibition with the FDA-approved drug Imatinib decreased RIPK3 signaling. We found that c-Abl interacts with RIPK3, that RIPK3 is phosphorylated at a tyrosine site, and that this phosphorylation is reduced when c-Abl is inhibited. Genetic ablation of c-Abl in neuronal GD and GD mice models significantly reduced RIPK3 activation and MLKL downstream signaling. These results showed that c-Abl signaling is a new upstream pathway that activates RIPK3 and that its inhibition is an attractive therapeutic approach for the treatment of GD.

RESUMO

OBJECTIVE: To update the Spanish Society of Neurology's guidelines for stroke prevention in patients with type 2 diabetes or prediabetes, analysing the available evidence on the effect of metabolic control and the potential benefit of antidiabetic drugs with known vascular benefits in addition to conventional antidiabetic treatments in stroke prevention. DEVELOPMENT: PICO-type questions (Patient, Intervention, Comparison, Outcome) were developed to identify practical issues in the management of stroke patients and to establish specific recommendations for each of them. Subsequently, we conducted systematic reviews of the PubMed database and selected those randomised clinical trials evaluating stroke as an independent variable (primary or secondary). Finally, for each of the PICO questions we developed a meta-analysis to support the final recommendations. CONCLUSIONS: While there is no evidence that metabolic control reduces the risk of stroke, some families of antidiabetic drugs with vascular benefits have been shown to reduce these effects when added to conventional treatments, both in the field of primary prevention in patients presenting type 2 diabetes and high vascular risk or established atherosclerosis (GLP-1 agonists) and in secondary stroke prevention in patients with type 2 diabetes or prediabetes (pioglitazone).

RESUMO

INTRODUCCIÓN: Para los trastornos temporomandibulares (TTM) el tratamiento de primera línea es el conservador, éste incluye a la terapia convencional, además se ha descrito el uso de la estimulación nerviosa eléctrica transcutánea (TENS). El objetivo de este estudio fue determinar la respuesta terapéutica del TENS como complemento a la terapia convencional comparado con pacientes que recibieron exclusivamente terapia convencional. MATERIAL Y MÉTODOS: Estudio retrospectivo caso-control en pacientes diagnosticados con TTM, tratados en la Clínica de Especialidades de la Escuela de Odontología de la Universidad de Valparaíso, entre los años 2009 y 2012. De los 231 pacientes, 63 cumplieron con los criterios de inclusión y fueron pareados en un grupo convencional y un grupo TENS. Se evaluó el dolor articular y muscular; aperturas mandibulares activa sin dolor, activa forzada y pasiva; y fuerza masticatoria. Se aplicaron test estadísticos de Kruskal-Wallis, Wilcoxon y Spearman. RESULTADOS: Para el grupo TENS, se encontraron respuestas significativas en dolor articular y muscular derecho e izquierdo, apertura mandibular activa sin dolor y fuerza masticatoria. Para el grupo convencional, se encontraron resultados similares a excepción de dolor articular derecho. También respuestas significativas para todas las variables que midieron dolor inmediatamente posterior a la aplicación de TENS. Finalmente se establecieron correlaciones entre la edad y las aperturas activa sin dolor, activa forzada y pasiva. DISCUSIÓN: La terapia convencional y la complementada con TENS demostraron similar respuesta terapéutica a largo plazo, sin embargo, la aplicación del TENS produce una respuesta inmediata que reduce el dolor en el corto plazo


INTRODUCTION: For temporomandibular disorders (TMD), conservative therapies, including conventional therapy, are the first line of treatment, and the use of transcutaneous electrical nerve stimulation (TENS) has also been reported. The aim of this study was to determine the therapeutic response to TENS as complement to conventional therapy compared with patients receiving conventional therapy exclusively. METHODOLOGY: A retrospective study was carried out with patients diagnosed with TMD, treated at the Clinic of Specialties of the Dental School of Universidad de Valparaíso, between 2009 and 2012. Of 231 patients, 63 met the inclusion criteria and were randomly allocated to a conventional therapy group (controls) and a coadjuvant TENS group (cases). Both were evaluated for pain in the temporomandibular joints (TMJ) and masseters, active opening without pain, forced active opening, passive opening, and occlusal force. Statistical analysis was performed with Kruskal-Wallis, Wilcoxon and Spearman tests. RESULTS: For TENS group, significant differences were found for pain in the right and left TMJ, pain in the right and left masseter, active opening without pain, and occlusal force. For the conventional group, the same results were obtained, except for pain in right TMJ. For the variables measured immediately after applying TENS, significant differences were found in all pain variables. Correlations were established with age, active opening without pain, forced active opening, and passive opening. DISCUSSION: Conventional therapy and TENS-complemented therapy showed good therapeutic response, concluding that TENS is a good complement to conventional therapy

RESUMO

OBJECTIVE: We present an update of the Spanish Society of Neurology's recommendations for prevention of both primary and secondary stroke in patients with dyslipidaemia. DEVELOPMENT: We performed a systematic review to evaluate the main aspects of the management of dyslipidaemias in primary and secondary stroke prevention and establish a series of recommendations. CONCLUSIONS: In primary prevention, the patient's vascular risk should be determined in order to define target values for low-density lipoprotein cholesterol. In secondary prevention after an atherothrombotic stroke, a target value <55mg/dL is recommended; in non-atherothombotic ischaemic strokes, given the unclear relationship with dyslipidaemia, target value should be established according to the vascular risk group of each patient. In both primary and secondary prevention, statins are the drugs of first choice, and ezetimibe and/or PCSK9 inhibitors may be added in patients not achieving the target value.
