Background and purpose: The aim of this study was to assess the possible pharmacological interactions between safinamide and antidepressants, and in particular the appearance of serotonin syndrome with data from real life. Methods: We conducted a retrospective observational study of patients with Parkinson's disease from our Movement Disorders Unit, who were under treatment with any antidepressant drug and safinamide. Specifically, symptoms suggestive of serotonin syndrome were screened for. Also, we collected time of simultaneous use, doses of levodopa and other antiparkinsonian drugs. Results: Clinical records were reviewed for the study period of September 2018 to September 2019. Seventy-eight PD patients who were treated with safinamide of which 25 (32.05%) had a concomitant treatment with an antidepressant drug, being sertraline and escitalopram the most frequent. Mean age was 80 years ± 8.43 and H&Y stage was 3 [2–4]. Mean dose of levodopa used was 703.75 mg ± 233.15. Median duration of concomitant treatment with safinamide and antidepressant drug was 6 months (IQR 20.5), and over eighteen months in 5 cases. No case of serotonin syndrome was recorded, neither was any of its typical manifestations combined or in isolation. Conclusions: Our real clinical practice study suggests that concomitant use of safinamide with antidepressant drugs in PD patients seemed to be safe and well tolerated, even in the long term. However, caution is warranted, individualizing treatment regimens and monitoring the potential appearance of adverse effects. Resumen: Objetivos: El objetivo de este estudio ha sido evaluar las posibles interacciones farmacológicas entre safinamida y antidepresivos; en particular la aparición del síndrome serotoninérgico mediante datos obtenidos en la vida real. Material y métodos: Realizamos un estudio observacional retrospectivo de pacientes con enfermedad de Parkinson (EP) de nuestra unidad de trastornos del movimiento, que estaban en tratamiento con algún fármaco antidepresivo y safinamida. Específicamente, se examinaron los síntomas sugestivos de síndrome serotoninérgico. Además, se recogieron tiempos de uso simultáneo, dosis de levodopa y otros fármacos antiparkinsonianos concomitantes. Resultados: Se revisaron las historias clínicas correspondientes al período de estudio de septiembre de 2018 a septiembre de 2019. Setenta y ocho pacientes con EP se encontraban en tratamiento con safinamida, de los cuales 25 (32,05%) se encontraban recibiendo además un fármaco antidepresivo, siendo sertralina y escitalopram los más frecuentes. La edad media fue de 80 años ± 8,43 y el estadio H&Y fue de 3 [2-4]. La dosis media de levodopa utilizada fue de 703,75 mg ± 233,15. La mediana de duración del tratamiento concomitante con safinamida y un fármaco antidepresivo fue de 6 meses (IQR: 20,5), y más de 18 meses en 5 casos. No se registró ningún caso de síndrome serotoninérgico, ni tampoco ninguno de sus síntomas de forma aislada. Conclusión: Nuestro estudio de práctica clínica real sugiere que el uso concomitante de safinamida con fármacos antidepresivos en pacientes con EP parece ser seguro y bien tolerado, incluso a largo plazo. Sin embargo, es necesaria precaución, individualizando los regímenes de tratamiento, y controlando la posible aparición de efectos adversos.

Resumen: Introducción: Se presenta una estrategia de interacción multidisciplinaria en medicina de posgrado cuyo objetivo es la actualización académica y la realización de actividades de investigación vinculadas con la lipidología pediátrica.

Discusión: Se propone la creación de grupos focales de discusión como una modalidad alternativa para desplazar los métodos tradicionales para mejorar la competencia médica y jerarquizar actitudes relevantes para el ejercicio profesional. Conclusiones: La formación en el posgrado se apoya en la integración de conocimientos y en la superación profesional, apelando a la responsabilidad y la autonomía, de las personas con formación universitaria. Abstract: Introduction: A multidisciplinary interaction strategy in postgraduate medicine is presented, which has as its aim the academic update and the carrying out of research activities related to paediatric lipidology. Development: Experience gained since 2010 is developed with the creation of a discussion and update group on disorders of lipid metabolism in paediatrics. This project is based on cooperative work and group ownership of knowledge, which includes the analysis of documents, clinical cases, surveys, and related bibliography. Discussion: The creation of focus groups as an alternative method is proposed to replace traditional medical methods, in order to improve competition, and to prioritise attitudes relevant to professional practice. Conclusions: Postgraduate training is based on the integration of knowledge and professional improvement, appealing to the responsibility and the autonomy of people with a university education.

Objective: To determine whether the left atrial size can predict the development of atrial fibrillation (AF) in patients with embolic stroke of undetermined source (ESUS). Methods: Patients with ischemic stroke were included prospectively (January 2015-July 2015) when ESUS was suspected. Clinical and cardiac imaging data were recorded. Patients with cardiac failure were excluded. Results: a total of 55 patients were included. Medium age was 71 years. The proportion of patients who developed AF during the follow-up (1 year) was 23, 63%. 10 % of patients did not have any vascular risk factor. Basal ECG was normal in 98% of cases. The left atrial size volume was 36, 08 ml in patients who developed AF and 27, 14 ml in patients who did not. Conclusions: In patients with ESUS, left atrial size dimensions do not predict the occurrence of AF.

Most patients with Parkinson's disease experience motor fluctuations or 'off' periods, which impact on their daily activities, increase their disability and diminish their quality of life. They suffer from these fluctuations despite multiple adjustments to the schedules, doses and intake of medication. In this context, on-demand or rescue treatments are necessary to attempt to improve 'off' periods, with drugs that have the pharmacokinetic advantage of a much faster onset of action because their routes of administration are not oral. There are currently three on-demand therapies for the treatment of fluctuations: subcutaneous apomorphine, inhaled levodopa and sublingual apomorphine. Of the three alternatives, subcutaneous apomorphine generally has the fastest onset of action, sublingual apomorphine provides the longest clinical effect, and inhaled levodopa has the most favourable side effect profile. Each of these drugs has its own characteristics: the time before onset of action, the duration of action and different side effect profiles. The choice for each patient will depend on their individual needs and circumstances. To mark the first year of the introduction of inhaled levodopa, we review these therapies, focusing on the experience with this new dosage form of levodopa.

Introduction: Functional neurological disorders (FND) are a frequent reason for visits in neurology. However, specific training on these disorders during undergraduate and residency training is limited. This study assesses the knowledge, attitude and exposure of medical students to FNDs before completing their medical degree., Patients and Methods: We conducted a 15-item survey to explore understanding, exposure and attitudes towards FNDs among sixth-year medical students at four Spanish universities., Results: A total of 118 students (mean age 23.6 ± 1.2 years; 71.2% female) returned the survey. Of these, 88 (74.6%) were aware of the concept of FNDs and 78 (66.1%) had studied them in psychiatry classes. The term 'psychosomatic' was chosen by 54.1% of the students as the most appropriate term to refer to these disorders, and 111 (94.1%) believed that a history of sexual or physical abuse was common among FND patients. Fifty-seven students (48.3%) assumed that the diagnosis of FND was mostly a clinical diagnosis of exclusion and 63 (53.4%) indicated that it is managed only by psychiatry. One hundred and one students (85.6%) considered that adequate training on FNDs is an important aspect of their medical training., Conclusions: Medical students are aware of the existence of FNDs, but their preferred terminology, as well as the perceived aetiological factors, reflect that the historical view of these disorders is still deeply rooted. Medical students feel that they should receive adequate education on FNDs from specialists in neurology and psychiatry as part of their training.

The role of immunosuppression among coronavirus disease 2019 (COVID-19) patients has not been elucidated and management may be challenging. This observational study included confirmed COVID-19 patients. The primary endpoint was the development of moderate-severe acute respiratory distress syndrome (ARDS). Time to moderate-severe ARDS, the need for mechanical or noninvasive ventilation (MV/NIV), death, and a composite of death or MV/NIV were secondary endpoints. Of 138 patients included, 27 (19.6%) were immunosuppressed (IS) and 95 (68.8%) were male, with a median (IQR) age of 68 (54-78) years. A significantly lower proportion of IS patients (25.9%) compared to non-IS patients (52.3%) developed moderate-severe ARDS, in both unadjusted (0.32; 95% CI, 0.13-0.83; p = .017) and adjusted (aOR, 0.25; 95% CI, 0.08-0.80; p = .019) analyses. After stratifying by pathologies, only IS patients with autoimmune diseases remained significant (aOR 0.25; 95% CI, 0.07-0.98; p = .046). Nonsignificant trends toward a longer time to moderate or severe ARDS, a lower need for MV/NIV, and a lower risk of death or MV/NIV were detected among IS. In our cohort of COVID-19 patients, nonsevere immunosuppression was associated with a lower risk of moderate-severe ARDS, especially among AD. This suggests a potential protective effect from a hypothesized hyper-inflammatory response., (© 2020 Wiley Periodicals LLC.)

Background: HHV7 reactivation has been occasionally reported as a cause of encephalitis or myelitis in transplant recipients, but to our knowledge it has never been associated with neurological disease in HIV-infected patients. We report a case of acute myelitis in an HIV-infected patient, with sustained HHV-7 DNA amplification in cerebrospinal fluid (CSF) and a favourable response to foscarnet., Case Report: A 40 year-old man with HIV infection was admitted with asymmetric hypoesthesia in legs and paraparesis. He was receiving treatment with efavirenz, emtricitabine and tenofovir, his CD4 count was 580/mm3 and HIV viral load was undetectable. Magnetic resonance imaging showed a focal central hyperintensity on T2 and STIR sequences, on the torathic spinal cord, with slight enhancement after intravenous gadolinium. All microbiological studies were negative except for HHV-7 DNA amplification in CSF. With a diagnosis of idiopathic transverse myelitis, treatment with high-dose intravenous methylprednisolone was initiated. However, paraparesis continued worsening, and a second CSF obtained 12 days after the first one resulted again in HHV-7 amplification., Results: The patient was treated with a 2 week course of foscarnet, and a rapid neurological improvement was noted. After treatment, PCR for HHV-7 in CSF was negative. Neurological exam was normal one month after treatment initiation., Conclusion: HHV-7 reactivation may cause neurological disease in patients with HIV infection. Foscarnet is an effective treatment in HHV-7 associated myelitis., (Copyright © 2016 Elsevier B.V. All rights reserved.)
