RESUMEN
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.
TITLE: Levodopa inhalada: de la evidencia a la experiencia.La mayoría de los pacientes con enfermedad de Parkinson sufren fluctuaciones motoras o períodos off, que impactan en sus actividades cotidianas, aumentan su discapacidad y empeoran su calidad de vida. A pesar de realizar múltiples ajustes en los horarios, en las dosis y en las tomas de medicación, no se consigue que estén libres de estas fluctuaciones. Es en este contexto en el que son necesarios los tratamientos a demanda o de rescate para tratar de mejorar los períodos off, con fármacos que tienen la ventaja farmacocinética de un inicio de acción mucho más rápido debido a que sus vías de administración no son orales. En la actualidad existen tres terapias a demanda para el tratamiento de las fluctuaciones: apomorfina subcutánea, levodopa inhalada y apomorfina sublingual. En general, la apomorfina subcutánea tiene un inicio de efecto más rápido, la apomorfina sublingual ofrece el efecto clínico más prolongado y la levodopa inhalada tiene el perfil de efectos secundarios más favorable entre las tres opciones. Cada uno de estos medicamentos tiene características únicas: tiempo de inicio, duración de acción y diferentes perfiles de efectos secundarios. La elección para cada paciente dependerá de sus necesidades y circunstancias individuales. Aprovechando el primer año de la introducción de la levodopa inhalada, revisamos estas terapias, centrándonos en la experiencia acumulada con esta nueva presentación galénica de levodopa.

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 [24]. 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.(AU)
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.(AU)

BACKGROUND: Different types of therapies were proven effective for the medical management of motor and non-motor symptoms in Parkinson's disease (PD). We aimed to gain consensus on the dopamine agonist (DA) therapy use in different clinical scenarios of Parkinson's disease (PD) patients. METHODS: This consensus study was based on the nominal group technique. Initially, a consensus group comprising 12 expert neurologists in the PD field identified the topics to be addressed and elaborated different evidence-based preliminary statements. Next, a panel of 48 Spanish neurologists expressed their opinion on an internet-based systematic voting program. Finally, initial ideas were reviewed and rewritten according to panel contribution and were ranked by the consensus group using a Likert-type scale. The analysis of data was carried out by using a combination of both qualitative and quantitative methods. The consensus was achieved if the statement reached ≥ 3.5 points in the voting process. RESULTS: The consensus group produced 76 real-world recommendations. The topics addressed included 12 statements related to DA therapy in early PD, 20 statements concerning DA treatment strategy in patients with motor complications, 11 statements associated with DA drugs and their side effects, and 33 statements regarding DA therapy in specific clinical scenarios. The consensus group did not reach a consensus on 15 statements. CONCLUSION: The findings from this consensus method represent an exploratory step to help clinicians and patients in the appropriate use of DA in different stages and clinical situations of PD.
RESUMEN
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.
TITLE: ¿Qué piensan los estudiantes de Medicina sobre los trastornos neurológicos funcionales?Introducción. Los trastornos neurológicos funcionales (TNF) son un motivo de consulta frecuente en neurología. Sin embargo, la formación específica sobre estos trastornos durante la formación universitaria y el período de residencia es limitada. En este estudio se evalúan los conocimientos, la actitud y la exposición de los estudiantes de Medicina a los TNF antes de terminar el grado de Medicina. Sujetos y métodos. Realizamos una encuesta de 15 ítems para explorar la comprensión, la exposición y las actitudes hacia los TNF entre los estudiantes de Medicina de sexto año en cuatro universidades españolas. Resultados. Devolvieron la encuesta 118 estudiantes (edad media 23,6 ± 1,2 años; 71,2%, mujeres). De ellos, 88 (74,6%) conocían el concepto de TNF y 78 (66,1%) los habían estudiado en las clases de psiquiatría. El 54,1% de los estudiantes eligió el término 'psicosomático' como el más adecuado para referirse a estos trastornos, y 111 (94,1%) creían que una historia de abuso sexual o físico era común entre los pacientes con TNF. Cincuenta y siete estudiantes (48,3%) asumieron que el diagnóstico de TNF era mayoritariamente un diagnóstico clínico de exclusión y 63 (53,4%) señalaron que el manejo se realiza únicamente desde psiquiatría. Ciento un estudiantes (85,6%) consideraron que una formación adecuada sobre los TNF es un aspecto importante de su formación médica. Conclusiones. Los estudiantes de Medicina son conscientes de la existencia de los TNF, pero la terminología preferida por ellos, así como los factores etiológicos percibidos, reflejan que la visión histórica acerca de estos trastornos está aún arraigada. Los estudiantes de Medicina consideran que deberían recibir una educación adecuada sobre los TNF como parte de su formación por parte de los especialistas en neurología y psiquiatría.

Introducción: La distonía focal de la mano es un trastorno del movimiento cuya sintomatología produce una alteración en el desempeño de tareas que requieren un nivel de destreza alto. Actualmente no se dispone de un modelo de interpretación de la enfermedad y son escasos los estudios que identifican las dificultades de las personas con distonía al desempeñar las actividades de la vida diaria (AVD). Por todo ello, el objetivo del estudio es describir la destreza manipulativa y su influencia en las AVD de los pacientes con distonía focal de la mano.Material y métodoSe realizó un estudio observacional, transversal, tipo casos y controles. Se reclutaron 24 participantes: 12 pacientes y 12 sujetos control. Los pacientes fueron derivados por el Servicio de Neurología del Hospital Ramón y Cajal. Se obtuvieron datos sociodemográficos y clínicos retrospectivos en el grupo de casos. Posteriormente, se administraron pruebas de evaluación, en el siguiente orden: Nine Hole Peg Test (NHPT), Box and Blocks Test (BBT), Purdue Pegboard Test (PPT) y Jebsen-Taylor Test of Hand Function (JTTHF).ResultadosEn la muestra del estudio participaron un total de 24 personas, siete mujeres y 17 hombres, con una media de edad de 50,79 ± 14,40 años. Del total de participantes con distonía focal se observó que, aunque la mitad de la muestra no identificó signos de afectación neuromuscular, ni problemas psicoemocionales, un menor porcentaje de estos pacientes identificaron dificultades asociadas con el hombro derecho (25%) y el estado ansioso (33,3%).ConclusionesLos hallazgos encontrados en el presente trabajo señalan que la distonía focal de la mano afecta a la destreza manipulativa de estos pacientes, presentando una peor ejecución y requiriendo más tiempo para su ejecución.

Introduction: Focal hand dystonia is a movement disorder whose symptoms cause alterations in the performance of tasks requiring a high level of dexterity. Currently, there is no model for interpreting the disease and few studies have identified the difficulties of patients with dystonia in carrying out activities of daily living (ADL). This study aims to describe manipulative dexterity and its influence on ADLs in patients with focal hand dystonia.Materials and methodsWe performed an observational, cross-sectional, case-control study including 24 participants (12 patients with focal hand dystonia and 12 controls). The patients were referred by the neurology department of Hospital Ramón y Cajal. We gathered sociodemographic data, as well as retrospective clinical data for patients. We subsequently administered evaluation tests, in the following order: Nine-Hole Peg Test (NHPT), Box and Blocks Test (BBT), Purdue Pegboard Test (PPT), and Jebsen-Taylor Test of Hand Function (JTTHF).ResultsThe study sample included a total of 24 participants, 7 women and 17 men, with a mean age (standard deviation) of 50.79 (14.40) years. In the patient group, neuromuscular involvement or psycho-emotional problems were not detected in half of cases; smaller numbers of patients presented difficulties associated with the right shoulder (25%) and anxious state (33.3%).ConclusionsOur results indicate that focal hand dystonia affects manipulative dexterity in these patients, who showed poorer performance and required more time to complete the tasks.

Introducción: Considerando las evidencias acumuladas actualmente es importante estudiar la fisiopatología tanto sensorial como motora de las distonías focales para comprenderlas y mejorar su tratamiento. Por ello, los objetivos del presente estudio son evaluar las aferencias somatosensoriales de los pacientes con distonía focal o segmentaria con afectación del miembro superior, comprobar si se corresponde con la mano de más uso, analizar la tolerancia al dolor y examinar la posible relación con la percepción del dolor en los pacientes con distonía segmentaria de la mano.MétodosSe contó con una muestra total de 24 participantes: 12 pacientes con distonía focal de la mano y 12 sujetos sin distonía. Todos ellos fueron evaluados con un algómetro electrónico (Somedic AB®, Farsta, Suecia), con los monofilamentos de Semmes-Weinstein y con la escala visual analógica.ResultadosLos datos hallados muestran, en la población estudiada, una mayor afectación en la sensibilidad superficial comparada con el grupo control, tanto en la mano dominante como en la no dominante, así como presencia de dolor (p > 0,001). Además, el grupo de distonía focal obtuvo una correlación negativa entre el dolor percibido y en el umbral de tolerancia de dolor a la presión (rho = −0,83; p < 0,001).ConclusionesLas personas con distonía segmentaria de la mano presentan una alteración en la sensibilidad y manifiestan mayor dolor percibido que las personas sin distonía. Se requieren más estudios con una muestra mayor que detecten las implicaciones clínicas y cotidianas, tanto del dolor objetivo como subjetivo. (AU)
Introduction: A growing body of evidence highlights the importance of understanding both the sensory and the motor pathophysiology of focal dystonia in order to improve its treatment. This study aims to evaluate somatosensory afferences in patients with focal or segmental dystonia affecting the upper limbs, to analyse whether the dominant limb is more frequently affected, to analyse pain tolerance, and to examine the potential association with pain perception in patients with hand dystonia.MethodsWe recruited 24 participants: 12 patients with focal hand dystonia and 12 individuals without dystonia. All participants were evaluated with a digital algometer (Somedic SenseLab AB®, Farsta, Sweden), a Semmes-Weinstein monofilament test, and the visual analogue scale for pain.ResultsAccording to our data, patients showed greater impairment in surface sensitivity than controls, both in the dominant and the non-dominant hands, as well as greater presence of pain (P > .001). Furthermore, the dystonia group showed a negative correlation between perceived pain and pressure pain tolerance threshold (rho = −0.83; P < .001).ConclusionsPatients with focal hand dystonia presented alterations in sensitivity and more severe perceived pain than individuals without dystonia. Future studies with larger samples should aim to analyse the clinical implications and everyday impact of both objective and subjective pain. (AU)

INTRODUCTION: Coronavirus disease 2019 (COVID-19) has spread rapidly, giving rise to a pandemic, causing significant morbidity and mortality. In this context, many vaccines have emerged to try to deal with this disease. OBJECTIVE: To review the reported cases of neurological manifestations after the application of COVID-19 vaccines, describing clinical, analytical and neuroimaging findings and health outcomes. METHODS: We carried out a review through bibliographic searches in PubMed. RESULTS: We found 86 articles, including 13 809 patients with a wide spectrum of neurological manifestations temporally associated with COVID-19 vaccination. Most occurred in women (63.89%), with a median age of 50 years. The most frequently reported adverse events were Bell's palsy 4936/13 809 (35.7%), headache (4067/13 809), cerebrovascular events 2412/13 809 (17.47%), Guillain-Barré syndrome 868/13 809 (6.28%), central nervous system demyelination 258/13 809 (1.86%) and functional neurological disorder 398/13 809 (2.88%). Most of the published cases occurred in temporal association with the Pfizer vaccine (BNT162b2), followed by the AstraZeneca vaccine (ChAdOX1-S). CONCLUSIONS: It is not possible to establish a causal relationship between these adverse events and COVID-19 vaccines with the currently existing data, nor to calculate the frequency of appearance of these disorders. However, it is necessary for health professionals to be familiar with these events, facilitating their early diagnosis and treatment. Large controlled epidemiological studies are necessary to establish a possible causal relationship between vaccination against COVID-19 and neurological adverse events.

Opicapone is a catechol-O-methyl-transferase (iCOMT) inhibitor authorized in Europe in 2016 and indicated as adjunctive therapy to preparations of levodopa/ DOPA decarboxylase inhibitors in adult patients with Parkinson's disease and end-of-dose motor fluctuations who cannot be stabilised on those combinations. The efficacy of opicapone in these patients has been demonstrated in two pivotal randomized clinical trials, BIPARK I and BIPARK II, in which it has demonstrated its superiority versus placebo and non-inferiority versus entacapone. Although they constitute the gold standard for the evaluation of interventions, randomized clinical trials present limitations of external validity due to the use of strict eligibility criteria. Therefore, it is considered necessary to have a more comprehensive evaluation of the efficacy of the drug, complementing the information obtained from randomized clinical trials with that of "real world or real clinical practice" studies. The objective of this review has been to collect and put into perspective the information available on opicapone coming from real clinical practice studies in Spain. The data from Spain with opicapone in 18 series with more than 1,000 patients in total, confirm the safety and efficacy previously reported with this iCOMT. Furthermore, they show that opicapone is especially useful in patients with a less advanced stage of the disease and mild motor fluctuations, which would suggest that the earlier its introduction in the therapeutic scheme for the management of motor fluctuations, the better is the benefit-risk ratio for the drug.
TITLE: Opicapona para el tratamiento de la enfermedad de Parkinson: datos de vida real en España.Resumen. La opicapona es un inhibidor de la catecol-O-metiltransferasa (iCOMT) autorizado en Europa en 2016 como terapia adyuvante a las preparaciones de levodopa/inhibidores de la dopa descarboxilasa en pacientes adultos con enfermedad de Parkinson y fluctuaciones motoras de final de dosis que no puedan ser estabilizados con esas combinaciones. La eficacia de la opicapona en estos pacientes ha sido demostrada en dos ensayos clínicos pivotales, BIPARK I y BIPARK II, en los que se ha demostrado la superioridad frente al placebo y la no inferioridad frente a la entacapona. A pesar de que constituyen el estándar para la evaluación de intervenciones, los ensayos clínicos aleatorizados presentan limitaciones de validez externa debidas a la utilización de criterios estrictos de elegibilidad. Por tanto, se considera necesario disponer de una evaluación más amplia de la eficacia general del fármaco, complementando la información de los ensayos clínicos aleatorizados con estudios de 'vida real o práctica clínica real'. El objetivo de esta revisión ha sido recopilar y poner en perspectiva la información disponible sobre los resultados de la opicapona en estudios de práctica clínica real en España. Los datos acumulados en España con opicapona en 18 series con más de 1.000 pacientes confirman la seguridad y la eficacia de este iCOMT comunicadas previamente. Además, muestran que la opicapona es especialmente útil en pacientes en un estadio de la enfermedad menos avanzado y fluctuaciones motores leves, lo que sugeriría una mejor relación beneficio-riesgo cuanto más temprana sea su introducción en el esquema terapéutico para el tratamiento de las fluctuaciones motoras.

La safinamida es un nuevo fármaco para el tratamiento de pacientes con enfermedad de Parkinson (EP) con fluctuaciones como tratamiento complementario a levodopa. Dado que por el momento aún no existen estudios de fase IV postautorización debido a la reciente incorporación de la safinamida a la práctica clínica habitual, el interés de este proyecto radica en el desarrollo de una guía de manejo clínico de la safinamida basada en las opiniones de expertos de trastornos del movimiento. Este proyecto se desarrolló en 2 fases: una primera fase que constó de 16 reuniones locales y una segunda fase que consistió en una reunión nacional. Dichas reuniones siguieron un guion de trabajo preestablecido. Tras la reunión nacional se recopilaron las principales conclusiones de los expertos, que han supuesto la base para redactar la presente guía clínica. Se concluyó que la safinamida es eficaz en la reducción de las fluctuaciones motoras y no motoras. Los pacientes con EP con fluctuaciones leves-moderadas son los que más se benefician del tratamiento, si bien el fármaco puede contribuir a mejorar diversos problemas clínicos en pacientes con EP avanzada. Se ha destacado la posibilidad de reducir la dosis de otros fármacos dopaminérgicos tras la introducción de la safinamida, lo cual contribuiría a reducir efectos adversos como el trastorno de control de impulsos. Se hipotetizó sobre el posible efecto de la safinamida sobre la mejoría de las discinesias a dosis más altas de las habitualmente utilizadas. Se ha consensuado que la safinamida es bien tolerada y presenta un perfil de efectos adversos favorable frente a placebo. (AU)
Safinamide is a new add-on drug to levodopa for the treatment of Parkinson's disease (PD) with motor fluctuations. Due to the recent incorporation of safinamide into routine clinical practice, no post-authorisation phase IV studies on the safety of safinamide have been conducted to date. This study provides clinical management guidelines for safinamide based on the opinion of a group of experts in movement disorders. This project was developed in 2 phases: 16 local meetings in phase 1 and a national meeting in phase 2. The meetings followed a pre-established agenda. The present clinical practice guidelines are based on the main conclusions reached during the national meeting. The group concluded that safinamide is effective in reducing motor and non-motor fluctuations. PD patients with mild-to-moderate fluctuations benefit most from treatment, although the drug may also improve the clinical status of patients with advanced PD. The dose of other dopaminergic drugs may be reduced after introducing safinamide, which would contribute to reducing such adverse reactions as impulse control disorder. At doses higher than those usually prescribed, safinamide may also improve dyskinesia. The experts agreed that safinamide is well tolerated and causes few adverse reactions when compared with placebo. (AU)

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 703.75mg±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
INTRODUCTION: In a degenerative disorder such as Parkinson's disease (PD), it is important to establish clinical stages that allow to know the course of the disease. Our aim was to analyze whether a scale combining Hoehn and Yahr's motor stage (H&Y) and the nonmotor symptoms burden (NMSB) (assessed by the nonmotor symptoms scale (NMSS)) provides information about the disability and the patient's quality of life (QoL) with regard to a defined clinical stage. MATERIALS AND METHODS: Cross-sectional study in which 603 PD patients from the COPPADIS cohort were classified according to H&Y (1, stage I; 2, stage II; 3, stage III; 4, stage IV/V) and NMSB (A: NMSS = 0-20; B: NMSS = 21-40; C: NMSS = 41-70; D: NMSS ≥ 71) in 16 stages (HY.NMSB, from 1A to 4D). QoL was assessed with the PDQ-39SI, PQ-10, and EUROHIS-QOL8 and disability with the Schwab&England ADL (Activities of Daily Living) scale. RESULTS: A worse QoL and greater disability were observed at a higher stage of H&Y and NMSB (p < 0.0001). Combining both (HY.NMSB), patients in stages 1C and 1D and 2C and 2D had significantly worse QoL and/or less autonomy for ADL than those in stages 2A and 2B and 3A and 3B, respectively (p < 0.005; e.g., PDQ-39SI in 1D [n = 15] vs 2A [n = 101]: 28.6 ± 17.1 vs 7.9 ± 5.8; p < 0.0001). CONCLUSION: The HY.NMSB scale is simple and reflects the degree of patient involvement more accurately than the H&Y. Patients with a lower H&Y stage may be more affected if they have a greater NMS burden.
RESUMEN
Introducción: La apomorfina, agonista dopaminérgico D1 y D2, es el fármaco más antiguo con efectividad en el tratamiento de la enfermedad de Parkinson (EP) y el único de potencia análoga a la levodopa. Su utilidad, tanto en la administración intermitente como en la perfusión continua en el control de las fluctuaciones motoras, está demostrada tanto en estudios abiertos como controlados. Objetivo: Analizar el papel de la apomorfina en las distintas manifestaciones y momentos evolutivos de la EP mediante una revisión narrativa de la literatura científica (1951-2020). Desarrollo: Más allá del aumento de la duración del on, la reducción del off, la mejoría de la distonía en off y la calidad de vida en pacientes con EP avanzada, existe evidencia de la efectividad de la apomorfina en áreas menos conocidas de la EP, como síntomas no motores, menor riesgo de inducir trastornos de control de impulsos, potencial para atenuar las alucinaciones visuales, mejora de la clínica neuropsiquiátrica asociada a la EP, ayuda a un mejor control de las discinesias o influencia en los síntomas axiales. Sin embargo, el momento óptimo de su instauración sigue siendo objeto de debate, y existen varios factores que históricamente han limitado el uso de este valioso fármaco. Conclusiones: La apomorfina es un fármaco con propiedades únicas dentro del abanico de posibilidades para tratar la EP, con potenciales aplicaciones más allá del control de las fluctuaciones motoras. Conocerlas para indicarlas a los pacientes que más puedan beneficiarse de ellos, así como valorar adecuadamente el estadio de la EP en que iniciar la apomorfina, puede ser clave para mejorar el control clínico de esta compleja patología.(AU)
Introduction: Apomorphine, a D1-D2 dopamine agonist, is the oldest drug with proven efficacy in the treatment of Parkinsons disease (PD), and the only with similar symptomatic power to levodopa. Its usefulness in the control of motor fluctuations, both as intermittent injections and in continuous subcutaneous infusion, has been demonstrated in open label and placebo controlled trials. Aim: To analyse the role of apomorphine in the varied clinical symptoms and different clinical stages of PD through a narrative review of scientific literature (1951-2020). Development: Beyond on-time increase, off-time decrease, off dystonia and quality of life improvement in advanced PD, there is evidence to support a role of apomorphine in less known clinical areas of PD, such as non motor symptoms, a lower risk of impulse control disorders, potential to ameliorate visual hallucinations, improve neuropsychiatric symptoms and dyskinesia and even axial features. Nevertheless, the optimal timing of apomorphine treatment remains controversial, and its implementation of this valuable drug in clinical practice has been historically hindered by several factors. Conclusions: Apomorphine is a unique drug in the PD treatment scenario, with a number of potential applications beyond motor fluctuations control. Acknowledging these properties, selecting the patient most likely to benefit from it and finding the right timing may be key in the symptomatic control of this complex disease.(AU)

INTRODUCTION: Parkinson's disease (PD) is more frequent in the elderly and increases the risk of respiratory infections. Previous data on PD and SARS-CoV-2 are scarce, suggesting a poor prognosis in advanced disease and second-line therapies. METHODS: A retrospective case-control study comparing patients with PD and COVID-19 and patients with PD without COVID-19 was conducted during the pandemic period in Spain (March 1st-July 31st 2020) in a tertiary university hospital. RESULTS: Thirty-nine (COVID-19 +) and 172 (COVID-19-) PD patients were included. Fifty-nine percent were males in both groups, with similar age (75.9 ± 9.0 COVID-19 + , 73.9 ± 10.0 COVID-19-), disease duration (8.9 ± 6.2 COVID-19 + , 8.5 ± 5.6 COVID-19-) and PD treatments. COVID-19 was mild in 10 (26%), required admission in 21 (54%) and caused death in 8 (21%) patients. Dementia was the only comorbidity more frequent in COVID-19 + patients (36% vs. 14%, p = 0.0013). However, in a multivariate analysis, institutionalization was the only variable associated with COVID-19 + (OR 17.0, 95% CI 5.0-60.0, p < 0.001). When considering severe COVID-19 (admission or death) vs. mild or absent COVID-19, institutionalization, neoplasm, dementia and a lower frequency of dopamine agonists were associated with severe COVID-19. In multivariate analysis, only institutionalization [OR 5.17, 95% CI 1.57-17, p = 0.004] and neoplasm [OR 8.0, 95%CI 1.27-49.8, p = 0.027] remained significantly associated. CONCLUSION: In our experience, institutionalization and oncologic comorbidity, rather than PD-related variables, increased the risk of developing COVID-19, and impacted on its severity. These findings suggest that epidemiologic factors and frailty are key factors for COVID-19 morbidity/mortality in PD. Appropriate preventive strategies should be implemented in institutionalized patients to prevent infection and improve prognosis.

INTRODUCTION: The main challenge of Parkinson's disease in women of childbearing age is managing symptoms and drugs during pregnancy and breastfeeding. The increase in the age at which women are having children makes it likely that these pregnancies will become more common in future. OBJECTIVES: This study aims to define the clinical characteristics of women of childbearing age with Parkinson's disease and the factors affecting their lives, and to establish a series of guidelines for managing pregnancy in these patients. RESULTS: This consensus document was developed through an exhaustive literature search and a discussion of the available evidence by a group of movement disorder experts from the Spanish Society of Neurology. CONCLUSIONS: Parkinson's disease affects all aspects of sexual and reproductive health in women of childbearing age. Pregnancy should be well planned to minimise teratogenic risk. A multidisciplinary approach should be adopted in the management of these patients in order to take all relevant considerations into account.
