RESUMO

Objetivo: El presente estudio tiene como objetivo proporcionar normas y ajustes para edad, educación y género para el Wisconsin Card Sorting Test (WCST), la Figura Compleja Modificada de Taylor (FCMT) y el Ruff-Light Trail Learning Test (RULIT) como parte del proyecto NEURONORMA-Plus. Método: La muestra consiste en 308 individuos cognitivamente sanos de entre 18 y 92 años. Se proporcionan tablas para convertir las puntuaciones brutas en puntuaciones escalares ajustadas por edad y ajustes por educación y género tras aplicar modelos de regresión independientes en 2 grupos de edad (< 50 y ≥ 50 años). Resultados: La edad tuvo un efecto negativo en el rendimiento en ambos grupos etarios. Observamos un efecto positivo de la educación en el rendimiento del WCST en el grupo más joven (< 50 años), y en todas las medidas del FCMT (con la excepción de la tarea de reconocimiento) en el grupo de mayor edad (≥ 50 años). La educación no influyó en el rendimiento en el RULIT, pero sí el género, que tuvo un efecto leve, aunque significativo, mostrando los hombres jóvenes un mayor rendimiento en una variable. Conclusión: Los datos normativos aportados pueden contribuir en la interpretación clínica del rendimiento en estas pruebas en población española.(AU)


Objective: The present study aims to provide norms and age-, education-, and sex-adjusted data for the Wisconsin Card Sorting Test (WCST), the Modified Taylor Complex Figure (MTCF), and the Ruff-Light Trail Learning Test (RULIT) as part of the NEURONORMA-Plus project. Methods: We recruited 308 cognitively healthy individuals aged between 18 and 92 years. Tables are provided to convert raw scores to age-adjusted scaled scores, as well as adjustments for education and sex after applying independent regression models in 2 age groups (< 50 and ≥ 50 years). Results: Older age had a negative effect on performance in both age groups. We observed a positive effect of education on WCST performance in the younger group (< 50 years), and on all MTCF measures (with the exception of the recognition task) in the older group (≥ 50 years). Education had no impact on performance in the RULIT, although sex did, with a small but significant effect whereby young men showed higher performance for one variable. Conclusion: The normative data provided can contribute to the clinical interpretation of performance in these tests in the Spanish population.(AU)

RESUMO

Introducción Las tareas de atención compleja y fluencia no verbal se utilizan en las valoraciones neuropsicológicas con el objetivo de explorar subdominios de las funciones ejecutivas. El objetivo de este estudio es proporcionar datos normativos ajustados por edad, escolaridad y género de las pruebas Delis Kaplan-Design Fluency Test (DK-DFT), Color Trails Tests (CTT) y Dual Task (DT) como parte del Proyecto NEURONORMA-Plus. Método Se incluyeron 308 individuos sin deterioro cognitivo de entre 18 y 92 años de edad. Se convirtieron las puntuaciones brutas en puntuaciones escalares ajustadas por edad y se realizaron ajustes por escolaridad y género aplicando regresiones lineales estratificando en dos grupos de edad (< 50 y ≥ 50 años). Resultados Globalmente la edad tuvo un impacto negativo en el DK-DFT y el CTT. La escolaridad mostró un efecto positivo en las puntuaciones del DK-DFT sólo en el grupo de mayor edad (≥ 50 años) y se halló un rendimiento discretamente superior en los hombres más jóvenes en la condición básica de esta prueba. La escolaridad se asoció positivamente con todas las puntuaciones de CTT en ambos grupos de edad, excepto en la subprueba CTT-1 en el grupo de adultos jóvenes. La edad y la escolaridad no mostraron influencia sobre el rendimiento en el DT, a diferencia del género, ya que las mujeres jóvenes tuvieron un rendimiento ligeramente superior. Conclusión Estos datos normativos pueden resultar útiles para la interpretación de las evaluaciones neuropsicológicas en población española. (AU)

RESUMO

Primary antiphospholipid syndrome is characterized by thrombosis and autoantibodies directed against phospholipids or associated proteins. The genetic etiology of PAPS remains unknown. We enrolled 21 patients with thromboembolic events associated to lupus anticoagulant, anticardiolipin and anti ß2 glycoprotein1 autoantibodies. We performed whole exome sequencing and a systematic variant-based analysis in genes associated with thrombosis, in candidate genes previously associated with APS or inborn errors of immunity. Data were compared to public databases and to a control cohort of 873 non-autoimmune patients. Variants were identified following a state-of-the-art pipeline. Enrichment analysis was performed by comparing with the control cohort. We found an absence of significant HLA bias and genetic heterogeneity in these patients, including when testing combinations of rare variants in genes encoding for proteins involved in thrombosis and of variants in genes linked with inborn errors of immunity. These results provide evidence of genetic heterogeneity in PAPS, even in a homogenous series of triple positive patients. At the individual scale, a combination of variants may participate to the breakdown of B cell tolerance and to the vessel damage.

RESUMO

We propose quantum neural networks that include multi-qubit interactions in the neural potential leading to a reduction of the network depth without losing approximative power. We show that the presence of multi-qubit potentials in the quantum perceptrons enables more efficient information processing tasks such as XOR gate implementation and prime numbers search, while it also provides a depth reduction to construct distinct entangling quantum gates like CNOT, Toffoli, and Fredkin. This simplification in the network architecture paves the way to address the connectivity challenge to scale up a quantum neural network while facilitating its training.

RESUMO

Ensembles of nitrogen-vacancy (NV) centers are used as sensors to detect nuclear magnetic resonance signals from micron-sized samples at room temperature. In this scenario, the regime of large magnetic fields is especially interesting as it leads to a large nuclear thermal polarization-thus, to a strong sensor response even in low concentration samples-while chemical shifts and J couplings become more accessible. Nevertheless, this regime remains largely unexplored owing to the difficulties of coupling NV-based sensors with high-frequency nuclear signals. In this Letter, we circumvent this problem with a method that maps the relevant energy shifts in the amplitude of an induced nuclear spin signal that is subsequently transferred to the sensor. This stage is interspersed with free-precession periods of the sample nuclear spins where the sensor does not participate. Thus, our method leads to high spectral resolutions ultimately limited by the coherence of the nuclear spin signal.

RESUMO

We present an invariant-based quantum control scheme leading to a highly monochromatic ion beam from a Paul trap. Our protocol is implementable by supplying the segmented electrodes in the trap with voltages of the order of volts. This mitigates the impact of fluctuations in previous designs and leads to a low-dispersion beam of ions. Moreover, our proposal does not rely on sympathetically cooling ions, which bypasses the need of loading different species in the trap-namely, the propelled ion and, e.g. a [Formula: see text] to exert sympathetic cooling-significantly incrementing the repetition rate of the launching procedure. Our scheme is based on an invariant operator linear in position and momentum, which enables us to control the average extraction energy and the outgoing momentum spread. In addition, we propose a sequential operation to tailor the transversal properties of the beam before the ejection to minimize the impact spot and to increase the lateral resolution of the implantation. This article is part of the theme issue 'Shortcuts to adiabaticity: theoretical, experimental and interdisciplinary perspectives'.

RESUMO

Background: Video-endoscopic inguinal lymphadenectomy (VEIL) is a minimally invasive approach that is increasingly indicated in oncological settings, with mounting evidence for its long-term oncological safety. Objectives: To present our single-center experience of treating penile and urethral cancer with VEIL, as well as its more recent application in melanoma patients. Methods: We prospectively recorded our experiences with VEIL from September 2010 to July 2018, registering the patient primary indication, surgical details, complications, and follow-up. Results: Twenty-nine patients were operated in one (24) or both (5) groins; 18 had penile cancer, 1 had urethral cancer, and 10 had melanoma. A mean 8.62 ± 4.45 lymph nodes were removed using VEIL and of these, an average of 1.00 ± 2.87 were metastatic; 16 patients developed lymphocele and 10 presented some degree of lymphedema; there were no skin or other major complications. The median follow-up was 19.35 months; there were 3 penile cancer patient recurrences in the VEIL-operated side. None of the melanoma patients presented a lymphatic inguinal recurrence. Conclusions: VEIL is a minimally invasive technique which appears to be oncologically safe showing fewer complications than open surgery. However, complications such as lymphorrhea, lymphocele, or lymphedema were not diminished by using VEIL.

RESUMO

Introducción: La evaluación del lenguaje en el contexto de las alteraciones neurológicas se fundamenta, tradicionalmente, en el uso de la lengua estándar de la comunidad en la que tiene lugar. Las variables dialectales constituyen un tema «olvidado». El objetivo de esta revisión es aportar recursos y guías de trabajo para superar esta limitación. Desarrollo: (1) Revisión de conceptos propios de la dialectología (lengua, dialecto, líneas isoglosas, idiolecto, registro, «variante estándar», bilingüismo). (2) Caracterización fundamental de las dialectologías española y catalana y búsqueda de recursos online para el desarrollo de instrumentos en neurología. (3) Búsqueda ad hoc en PubMed (palabras clave: dialect, aphasia, multilingual). Conclusiones: (1) Se aportan recursos online para promover un adecuado desarrollo de instrumentos de evaluación en lenguas castellana y catalana, considerando aspectos dialectales. (2) Se aportan unas guías de trabajo orientadas a la introducción de variables dialectales en los test de lenguaje para asegurar su objetivo último: evaluar el uso real de la lengua, y no el conocimiento cultural de la lengua estándar. (AU)


Introduction: In the context of neurological disorders, language assessment is traditionally based on the use of the standard language of the community in which the assessment is performed. Dialectal variables constitute a ‘forgotten’ topic. This review aims to provide resources and working guidelines to overcome this limitation. Development: The study was conducted as follows: 1) review of basic concepts of dialectology (language, dialect, isogloss line, idiolect, register, ‘standard variant’, bilingualism); 2)characterisation of Spanish and Catalan dialectologies and search for online resources for the development of neurological assessment tools; 3) ad hoc search on the PubMed database (keywords ‘dialect’, ‘aphasia’ and ‘multilingual’). Conclusions: We provide online resources to promote adequate development of assessment tools in Spanish and Catalan, accounting for Dialectal considerations. We propose a set of working guidelines for the introduction of Dialectal variables in language tests to ensure their ultimate objective: to evaluate the real use of the language, and not cultural knowledge of the standard language.

RESUMO

INTRODUCTION: The analysis of the core biomarkers of Alzheimer's Disease (AD) in the cerebrospinal fluid (CSF) is recommended in the clinical units where it is available. Because of the absence of universal validated values, the determination of specific cut-off points for each center and its population is recommended. The main objective of the CORCOBIA study was to determine the cut-off points of core AD CSF biomarkers for several centers (Parc de Salut Mar, Barcelona and Hospital General de Granollers), which work with the same reference laboratory (Laboratori de Referència de Catalunya). METHODS: Prospective study including cognitively unimpaired individuals (CU, n = 42), subjects with amnestic mild cognitive impairment (aMCI, n = 35) and patients with dementia due to Alzheimer's Disease (AD, n = 48), in whom clinical and neuropsychological assessment, neuroimaging, APOE genotyping and lumbar puncture to analyse amyloid beta peptides (Aß42, Aß40), total tau (tTau) and phosphorylated Tau (pTau181) using the Lumipulse G600II (Fujirebio) was performed. The values of sensitivity (SE), specificity (SP), predictive values and area under the curve (AUC) were calculated, determining the cut-off point according to the Youden index by comparing the CU and AD groups. RESULTS: The resulting cut-offs and their AUC were the following: Aß42 750 pg/mL (AUC 0.809); Aß42/Aß40 0.062 (AUC 0.78); pTau181 69.85 pg/mL (AUC 0.81); tTau 522.0 pg/mL (AUC 0.79); Aß42/tTau 1.76 (AUC 0.86); Aß42/pTau181 10.25 (AUC 0.86). CONCLUSIONS: The determination of cut-off points of core AD CSF biomarkers for the participating centers allows a better diagnostic accuracy. The ratio CSF Aß42/pTau181 shows the highest AUC and better balance between sensitivity and specificity.

RESUMO

INTRODUCTION: The Free and Cued Selective Reminding Test (FCSRT) is widely used for the assessment of verbal episodic memory, mainly in patients with Alzheimer disease. A Spanish-language version of the FCSRT and normative data were developed within the NEURONORMA project. Availability of alternative, equivalent versions is useful for following patients up in clinical settings. This study aimed to develop an alternative version of the original FCSRT (version B) and to study its equivalence to the original Spanish-language test (version A), and its performance in a sample of healthy individuals, in order to develop reference data. METHODS: We evaluated 232 healthy participants of the NEURONORMA-Plus project, aged between 18 and 90. Thirty-three participants were assessed with both test versions using a counterbalanced design. RESULTS: High intra-class correlation coefficients (between 0.8 and 0.9) were observed in the equivalence study. While no significant differences in performance were observed in total recall scores, free recall scores were significantly lower for version B. CONCLUSIONS: These preliminary results suggest that the newly developed FCSRT version B is equivalent to version A in the main variables tested. Further studies are necessary to ensure interchangeability between versions. We provide normative data for the new version.

RESUMO

INTRODUCTION: Complex attention and non-verbal fluency tasks are used in neuropsychological assessments with the aim of exploring subdomains of executive function. The purpose of this study is to provide norms and age-, education-, and sex-adjusted data for the Delis Kaplan-Design Fluency Test (DK-DFT), Color Trails Test (CTT), and Dual Task (DT) as part of the NEURONORMA-Plus project. METHODS: The sample included 308 cognitively healthy individuals aged between 18 and 92 years. Raw scores were converted to age-adjusted scaled scores. These were further converted into education- and sex-adjusted scaled scores by applying linear regression, with 2 age groups (< 50 and ≥ 50 years). RESULTS: Overall, age had a negative impact on DK-DFT and CTT performance. We observed a positive effect of education on DK-DFT scores only in the older group (≥ 50 years). Moreover, younger men performed slightly better in the basic condition of this test. Education was positively associated with all CTT scores in both age groups, with the exception of the CTT-1 subtest in the younger group. Age and education did not influence DT performance, whereas sex did, with young women performing slightly better. CONCLUSIONS: These normative data may be useful in the interpretation of neuropsychological assessments in the Spanish population.

RESUMO

BACKGROUND: Subacute sclerosing panencephalitis (SSPE) is a rare, non-treatable and fatal neurological complication of measles, still present due to the return of the epidemic linked to the loosening of vaccination policies. Its mechanism remains unexplained. OBJECTIVE: The main objective was to investigate explanatory variables relating to the risk of developing SSPE and its pathophysiology. METHODS: Literature analysis was focused on different varieties of SSPE: perinatal forms, short-incubation forms similar to acute measles inclusion body encephalitis (MIBE), rapidly evolving forms, forms occurring in the immunosuppressed, adult forms, and family forms. In addition, several studies on the parameters of innate immunity and interferon responses of patients were analyzed. RESULTS: Two main data were highlighted: a relationship between the so-called fulminant forms and the prescription of corticosteroids was established. In familial SSPE, two groups were individualized according to the duration of the latency period, prompting an analysis of patient exomes. CONCLUSION: Treatment with corticosteroids should be banned. Knowledge of the genes involved and epigenetics should be useful for understanding the pathophysiology of SSPE and other late-onset neurological infections with RNA viruses.

RESUMO

Introducción: El test Free and Cued Selective Reminding Test (FCSRT) es una prueba de uso extendido para evaluar la memoria episódica verbal, principalmente en el ámbito de la enfermedad de Alzheimer. Existe una versión española de la prueba con datos normativos proveniente del proyecto NEURONORMA.ES. Disponer de versiones alternativas equivalentes de las pruebas resulta útil para el seguimiento de los pacientes en la práctica clínica. El objetivo del presente estudio es ofrecer una versión alternativa a la original, denominada «B», estudiar su equivalencia con la versión original española (A) y el rendimiento en la misma de una muestra de sujetos para proporcionar datos de referencia.MétodosSe evaluaron 232 sujetos sanos de entre 18 y 90 años en el contexto del proyecto NEURONORMA-Plus. A 33 de ellos se les administraron ambas versiones con un diseño contrabalanceado.ResultadosEn el estudio de equivalencia se observaron coeficientes de correlación intraclase elevados (entre 0,8 y 0,9) y diferencias no significativas en las variables de recuerdo total. Sin embargo, sí se hallaron diferencias significativas en los ensayos de evocación libre, en los que el rendimiento en la nueva versión fue menor.ConclusionesLos resultados iniciales sugieren que la versión B del FCSRT aquí presentada resulta equivalente a la versión A en las variables principales de la prueba. Se requieren de futuros estudios para asegurar la total intercambiabilidad entre versiones. Se aportan datos normativos de la versión presentada. (AU)

RESUMO

The quantum perceptron is a fundamental building block for quantum machine learning. This is a multidisciplinary field that incorporates abilities of quantum computing, such as state superposition and entanglement, to classical machine learning schemes. Motivated by the techniques of shortcuts to adiabaticity, we propose a speed-up quantum perceptron where a control field on the perceptron is inversely engineered leading to a rapid nonlinear response with a sigmoid activation function. This results in faster overall perceptron performance compared to quasi-adiabatic protocols, as well as in enhanced robustness against imperfections in the controls.
