Background and purpose: The purpose was to perform a nationwide epidemiological study of Guillain–Barré syndrome (GBS) in Spain, analysing background incidences and seasonal variation and trying to identify incidence changes during the coronavirus disease 2019 (COVID‐19) years. Methods: This was an observational study collecting all GBS diagnoses from the National Epidemiological Surveillance Network collected by the Ministry of Health. Patients discharged with GBS as the main diagnosis and admitted during 2018–2021 were included. Data on the incidence of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infections were obtained from the National Epidemiology Centre. Results: In total, 3147 cases were included, 832 in 2018, 861 in 2019, 670 in 2020 and 784 in 2021. Nationwide hospital incidence was 1.78 in 2018, 1.71 in 2019, 1.41 in 2020 and 1.66 in 2021, with an increased frequency in males, the elderly population and in the winter season. Eleven per cent of GBS patients needed ventilatory support. GBS and SARS‐CoV‐2 incidences did not correlate with one another (r = −0.29, p = 0.36). GBS incidence decreased during 2020 and during the COVID‐19 lockdown period in comparison to the same months of 2018–2019. Conclusions: The incidence of GBS in Spain is similar to that of other countries. Despite prior reports describing a significant increase in COVID‐19‐associated GBS in Spain, a significant drop of GBS incidence during the SARS‐CoV‐2 pandemic was detected, probably due to prevention measures.

- Abstract
[Objective] To describe the clinical characteristics and outcomes in patients with refractory myasthenia gravis (MG) and to determine the effectiveness and side effects of the drugs used for their treatment., [Methods] This observational retrospective cross-sectional multicenter study was based on data from the Spanish MG Registry (NMD-ES). Patients were considered refractory when their MG Foundation of America post-interventional status (MGFA-PIS) was unchanged or worse after corticosteroids and two or more other immunosuppressive agents. Clinical and immunologic characteristics of drug-refractory patients, efficiency and toxicity of drugs used, and outcome (MGFA-PIS) at end of follow-up were studied., [Results] We included 990 patients from 15 hospitals. Eighty-four patients (68 of 842 anti-acetylcholine receptor [AChR], 5 of 26 anti-muscle-specific tyrosine kinase [MusK], 10 of 120 seronegative, and 1 of 2 double-seropositive patients) were drug refractory. Drug-refractory patients were more frequently women (p < 0.0001), younger at onset (p < 0.0001), and anti-MuSK positive (p = 0.037). Moreover, they more frequently presented a generalized form of the disease, bulbar symptoms, and life-threatening events (p < 0.0001; p = 0.018; and p = 0.002, respectively) than non-drug-refractory patients. Mean follow-up was 9.8 years (SD 4.5). Twenty-four (50%) refractory patients had side effects to one or more of the drugs. At the end of follow-up, 42.9% of drug-refractory patients (42.6% of anti-AChR, 100% of anti-MuSK, and 10% of seronegative patients) and 79.8% of non-drug-refractory patients (p < 0.0001) achieved remission or had minimal manifestations. Eighty percent of drug-refractory-seronegative patients did not respond to any drug tested., [Interpretation] In this study, 8.5% of MG patients were drug-refractory. New more specific drugs are needed to treat drug-refractory MG patients.

La recent descripció d'autoanticossos patogènics contra proteïnes de la mielina i del node/paranode de Ranvier en pacients amb polirradiculoneuropatia inflamatòria desmielinitzant crònica (CIDP) ha revelat l'existència de diferents subtipus de la malaltia amb mecanismes patogènics diferents que es tradueixen en fenotips clínics específics i una resposta selectiva als tractaments immunomoduladors. Malgrat aquests avenços, només es detecten autoanticossos en aproximadament un 15% dels pacients amb CIDP. En aquesta tesi investiguem la presència d'anticossos anti-MAG i anti-Caspr1/CNTN1 en pacients amb CIDP. Els anticossos anti-MAG apareixen gairebé invariablement en el context d'una neuropatia associada a gammapatia monoclonal IgM. S'han reportat molt pocs casos de neuropatia anti-MAG sense gammapatia monoclonal IgM associada. La detecció d'anticossos anti-MAG en pacients que compleixen criteris diagnòstics de CIDP pot tenir implicacions diagnòstiques, terapèutiques i pronòstiques. En aquest estudi investiguem la presència d'anticossos anti-MAG en 69 pacients que complien els criteris diagnòstics EFNS/PNS de CIDP i que no tenien una gammapatia monoclonal IgM detectable en el moment del diagnòstic. Els anticossos anti-MAG es van testar mitjançant ELISA i es van confirmar amb immunohistoquímica. Vam recopilar dades clíniques, neurofisiològiques i de laboratori dels pacients anti-MAG positius. Identificarem 4 (5,8%) pacients amb anticossos anti-MAG sense gammapatia monoclonal IgM detectable. Tots van presentar un quadre progressiu amb símptomes predominantment sensitius, atàxia i/o tremolor. En dos d'ells es va detectar una gammapatia monoclonal IgM als 3 i 4 anys de seguiment coincidint amb un augment dels títols d'anticossos anti-MAG. Estudis previs han descrit les característiques clínico-patològiques de pacients amb CIDP i anticossos contra les proteïnes paranodals neurofascina-155, contactina-1 (CNTN1) i proteïna associada a contactina-1 (Caspr1). Aquests anticossos són útils per al diagnòstic i maneig terapèutic d'aquests pacients. Els anticossos contra Caspr1 o contra el complex Caspr1/CNTN1 s'han descrit en molt pocs pacients amb CIDP. Mitjançant assajos basats en cèl·lules (CBA) utilitzats en la rutina assistencial identificarem sèrums de 15 pacients amb CIDP que mostraven una forta reactivitat de membrana quan la CNTN1 i el Caspr1 es co-transfectaven (però no quan CNTN1 es transfectava de forma aïllada). La prevalença d'anticossos anti-Caspr1/CNTN1 va ser de l'1,9% (1/52) en la cohort de CIDP de Sant Pau i de l'4,3% (1/23) en una cohort alemanya de CIDP d'inici agut. Tots els pacients van complir amb els criteris diagnòstics EFNS/PNS definitius de CIDP. Set (47%) van ser diagnosticats inicialment de síndrome de Guillain-Barré a causa d'un inici agut-subagut. Sis (40%) pacients tenien afectació de parells cranials, vuit (53%) tenien dolor neuropàtic i 12 (80%) atàxia. Els estudis electrofisiològics van mostrar una afectació axonal primerenca. No es va observar una resposta completa als tractaments de primera línia, mentre que la majoria (90%) va respondre bé al rituximab. L'ELISA i la immunohistoquímica de fibres nervioses van confirmar la reactivitat contra el complex paranodal Caspr1/CNTN1. També es va detectar una reactivitat més feble contra cèl·lules transfectades només amb Caspr1 en 10 de 15 (67%). Els sèrums de 13 d'aquests pacients van ser testats mitjançant ELISA. Les 13 mostres van reaccionar contra Caspr1 per ELISA i aquesta reactivitat va augmentar quan a l'ELISA de Caspr1 se li afegia CNTN1. En l'estudi de subclasses d'IgG mitjançant ELISA la subclasse predominant va ser la IgG4 en 10 pacients, mentre que IgG3 va ser el predominant en tres pacients. Conclusió: L'estudi d'anticossos anti-MAG s'ha de considerar en pacients amb neuropatia desmielinitzant crònica, fins i tot en absència de gammapatia monoclonal IgM detectable, ja que la seva detecció pot tenir implicacions en el pronòstic i maneig terapèutic d'aquests pacients. Els pacients amb anticossos contra el complex Caspr1/CNTN1 presenten característiques serològiques i clíniques similars i constitueixen un subgrup definit dins de la síndrome de la CIDP. La reciente descripción de autoanticuerpos patogénicos contra proteínas de la mielina y del nodo/paranodo de Ranvier en pacientes con polirradiculoneuropatía inflamatoria desmielinizante crónica (CIDP) ha revelado la existencia de distintos subtipos de enfermedad con mecanismos patogénicos diferentes que se traducen en fenotipos clínicos específicos y una respuesta selectiva a los tratamientos inmunomoduladores. A pesar de estos avances, solo se detectan autoanticuerpos en aproximadamente el 15% de los pacientes con CIDP. En esta tesis investigamos la presencia de anticuerpos anti-MAG y anti-Caspr1/CNTN1 en pacientes con CIDP. Los anticuerpos anti-MAG aparecen casi invariablemente en el contexto de una neuropatía asociada a gammapatía monoclonal IgM. Se han reportado muy pocos casos de neuropatía anti-MAG sin gammapatía monoclonal IgM asociada. La detección de anticuerpos anti-MAG en pacientes que cumplen criterios diagnósticos de CIDP puede tener implicaciones diagnósticas, terapéuticas y pronósticas. En este estudio investigamos la presencia de anticuerpos anti-MAG en 69 pacientes que cumplían los criterios diagnósticos EFNS/PNS de CIDP y que no tenían gammapatía monoclonal IgM detectable en el momento del diagnóstico. Los anticuerpos anti-MAG se testaron mediante ELISA y se confirmaron mediante inmunohistoquímica. Recopilamos datos clínicos, neurofisiológicos y de laboratorio de los pacientes anti-MAG positivos. Identificamos cuatro (5,8%) pacientes con anticuerpos anti-MAG sin gammapatía monoclonal IgM detectable. Todos presentaron un cuadro progresivo con síntomas predominantemente sensitivos, ataxia y/o temblor. En dos de ellos se detectó gammapatía monoclonal IgM a los 3 y 4 años de seguimiento coincidiendo con un aumento de los títulos de anticuerpos anti-MAG. Estudios previos han descrito las características clínico-patológicas de pacientes con CIDP y anticuerpos contra las proteínas paranodales neurofascina-155, contactina-1 (CNTN1), proteína asociada a contactina-1 (Caspr1). Estos anticuerpos son útiles para el diagnóstico y manejo terapéutico de estos pacientes. Los anticuerpos contra Caspr1 o contra el complejo Caspr1/CNTN1 se han descrito en muy pocos pacientes con CIDP. Mediante ensayos basados en células (CBA) utilizados en rutina asistencial identificamos sueros de 15 pacientes con CIDP que mostraban una fuerte reactividad de membrana cuando tanto CNTN1 y Caspr1 se co-transfectaban (pero no cuando CNTN1 se transfectaba de forma aislada). La prevalencia de anticuerpos anti-Caspr1/CNTN1 fue del 1,9% (1/52) en la cohorte de CIDP de Sant Pau y del 4,3% (1/23) en una cohorte alemana de CIDP de inicio agudo. Todos los pacientes cumplieron con los criterios diagnósticos EFNS/PNS definitivos de CIDP. Siete (47%) fueron diagnosticados inicialmente de síndrome de Guillain-Barré debido a un inicio agudo-subagudo. Seis (40%) pacientes tenían afectación de pares craneales, ocho (53%) dolor neuropático y 12 (80%) ataxia. Los estudios electrofisiológicos mostraron afectación axonal temprana. No se observó una respuesta completa a los tratamientos de primera línea, mientras que la mayoría (90%) respondió bien al rituximab. El ELISA y la inmunohistoquímica de preparaciones de fibras nerviosas confirmaron la reactividad contra el complejo paranodal Caspr1/CNTN1. También se detectó una reactividad más débil contra células transfectadas solo con Caspr1 en 10 de 15 (67%). Los sueros de 13 de estos pacientes fueron testados mediante ELISA. Las 13 muestras reaccionaron contra Caspr1 por ELISA y esta reactividad aumentó cuando al ELISA de Caspr1 se le añadía CNTN1. En el estudio de subclases de IgG mediante ELISA la subclase predominante fue IgG4 en 10 pacientes, mientras que IgG3 fue predominante en otros tres pacientes. Conclusión: El estudio de anticuerpos anti-MAG debe considerarse en pacientes con neuropatía desmielinizante crónica, incluso en ausencia de gammapatía monoclonal IgM detectable, pues su detección puede tener implicaciones en el pronóstico y manejo terapéutico de estos pacientes. Los pacientes con anticuerpos contra el complejo Caspr1/CNTN1 presentan características serológicas y clínicas similares y constituyen un subgrupo definido dentro del síndrome de la CIDP. The recent description of pathogenic autoantibodies against myelin and nodal/paranodal proteins in patients with chronic demyelinating inflammatory polyradiculoneuropathy (CIDP) has revealed the existence of disease subtypes with diverse pathogenic mechanisms leading to specific clinical phenotypes and a selective response to immunomodulatory treatments. Despite these advances, autoantibodies are only detected in approximately 15% of patients with CIDP. In this thesis we investigate the presence of anti-MAG and anti-Caspr1/CNTN1 antibodies in CIDP patients. Antibodies against myelin-associated glycoprotein (MAG) almost invariably appear in the context of an IgM monoclonal gammopathy associated neuropathy. Very few cases of anti-MAG neuropathy lacking IgM-monoclonal gammopathy have been reported. Detection of anti-MAG antibodies in patients fulfilling CIDP diagnostic criteria may have diagnostic, therapeutic and prognostic implications. In this study we investigated the presence of anti-MAG antibodies in 69 patients fulfilling diagnostic criteria for chronic inflammatory demyelinating polyneuropathy (CIDP). Anti-MAG antibodies were tested by ELISA and confirmed by immunohistochemistry. We collected clinical, neurophysiological and laboratory data of anti-MAG positive patients. We identified four (5.8%) anti-MAG positive patients without detectable IgM-monoclonal gammopathy. All patients presented with progressive sensory disturbances, ataxia and/or tremor. In two of them, IgM-monoclonal gammopathy was detected at 3 and 4-year follow-up coinciding with an increase in anti-MAG antibodies titers. Previous studies have described the clinical, serological and pathological features of patients with CIDP and antibodies directed against the paranodal proteins neurofascin-155, contactin-1 (CNTN1), contactin-associated protein-1 (Caspr1). Such antibodies are useful for diagnosis and, potentially, for treatment selection. However, antibodies targeting Caspr1-only or the Caspr1/CNTN1 complex have been reported in very few CIDP patients. Using cell-based assays (CBAs) in routine clinical testing, we identified sera from 15 CIDP patients showing strong membrane reactivity when both CNTN1 and Caspr1 were co-transfected (but not when CNTN1 was transfected alone). The prevalence of anti-Caspr1/CNTN1 antibodies was 1.9% (1/52) in the Sant Pau CIDP cohort, and 4.3% (1/23) in a German cohort of acute-onset CIDP. All patients fulfilled EFNS/PNS definite diagnostic criteria for CIDP. Seven (47%) were initially diagnosed with GBS due to an acute-subacute onset. Six (40%) patients had cranial nerve involvement, eight (53%) reported neuropathic pain and 12 (80%) ataxia. Early axonal involvement was frequent in electrophysiological studies. Complete response to first line treatments was not observed, while most (90%) responded well to rituximab. ELISA and teased-nerve fibre immunohistochemistry confirmed reactivity against the paranodal Caspr1/CNTN1 complex. Weaker reactivity against Caspr1 transfected alone was also detected in 10/15 (67%). Sera from 13 of these patients were available for testing by ELISA. All 13 samples reacted against Caspr1 by ELISA and this reactivity was enhanced when CNTN1 was added to the Caspr1 ELISA. IgG subclasses were also investigated by ELISA. IgG4 was the predominant subclass in 10 patients, while IgG3 was predominant in other three patients. Conclusion: Anti-MAG antibody testing should be considered in patients with chronic demyelinating neuropathy, even if IgM-monoclonal gammopathy is not detectable, since its detection may have implications in the prognosis and therapeutic management of these patients. Patients with antibodies to the Caspr1/CNTN1 complex display similar serological and clinical features and constitute a single subgroup within the CIDP syndrome. Universitat Autònoma de Barcelona.

- Abstract
La recent descripció d'autoanticossos patogènics contra proteïnes de la mielina i del node/paranode de Ranvier en pacients amb polirradiculoneuropatia inflamatòria desmielinitzant crònica (CIDP) ha revelat l'existència de diferents subtipus de la malaltia amb mecanismes patogènics diferents que es tradueixen en fenotips clínics específics i una resposta selectiva als tractaments immunomoduladors. Malgrat aquests avenços, només es detecten autoanticossos en aproximadament un 15% dels pacients amb CIDP. En aquesta tesi investiguem la presència d'anticossos anti-MAG i anti-Caspr1/CNTN1 en pacients amb CIDP. Els anticossos anti-MAG apareixen gairebé invariablement en el context d'una neuropatia associada a gammapatia monoclonal IgM. S'han reportat molt pocs casos de neuropatia anti-MAG sense gammapatia monoclonal IgM associada. La detecció d'anticossos anti-MAG en pacients que compleixen criteris diagnòstics de CIDP pot tenir implicacions diagnòstiques, terapèutiques i pronòstiques. En aquest estudi investiguem la presència d'anticossos anti-MAG en 69 pacients que complien els criteris diagnòstics EFNS/PNS de CIDP i que no tenien una gammapatia monoclonal IgM detectable en el moment del diagnòstic. Els anticossos anti-MAG es van testar mitjançant ELISA i es van confirmar amb immunohistoquímica. Vam recopilar dades clíniques, neurofisiològiques i de laboratori dels pacients anti-MAG positius. Identificarem 4 (5,8%) pacients amb anticossos anti-MAG sense gammapatia monoclonal IgM detectable. Tots van presentar un quadre progressiu amb símptomes predominantment sensitius, atàxia i/o tremolor. En dos d'ells es va detectar una gammapatia monoclonal IgM als 3 i 4 anys de seguiment coincidint amb un augment dels títols d'anticossos anti-MAG. Estudis previs han descrit les característiques clínico-patològiques de pacients amb CIDP i anticossos contra les proteïnes paranodals neurofascina-155, contactina-1 (CNTN1) i proteïna associada a contactina-1 (Caspr1).

- Abstract
Introduction/Aims: Very few studies analyzing the pattern of muscle involvement in magnetic resonance imaging (MRI) of patients with McArdle disease have been reported to date. We aimed to examine the pattern of muscle fat replacement in patients with McArdle disease. Methods: We performed a retrospective study including all patients with genetically confirmed McArdle disease followed in our center from January 2010 to March 2021. Clinical data were collected from the medical record. Whole‐body MRI was performed as part of the diagnostic evaluation. The distribution of muscle fat replacement and its severity were analyzed. Results: Nine patients were included. Median age at onset was 7 y (range, 5–58) and median age at the time when MRI was performed was 57.3 y (range, 37.2–72.8). At physical examination, four patients had permanent weakness: in three the weakness was limited to paraspinal muscles, whereas in one the weakness involved the paraspinal and proximal upper limb muscles. Muscle MRI showed abnormalities in six of the seven studied patients. In all of them, fat replacement of paravertebral muscles was found. Other muscles frequently affected were the tongue in three, subscapularis in three, and long head of biceps femoris and semimembranosus in two. Discussion: Our findings suggest that paraspinal muscle involvement is common in McArdle disease and support the need to include this disease in the differential diagnosis of the causes of paraspinal muscle weakness. Involvement of the tongue and subscapularis are also frequent in McArdle disease. [ABSTRACT FROM AUTHOR]

- Abstract
The clinical spectrum of Enterovirus-71-associated neurological disease includes acute flaccid paralysis, encephalomyelitis, or brainstem encephalitis with autonomic dysfunction. As no specific antiviral treatments are available, intravenous human immunoglobulin is used in early stages of the illness, decreasing serum proinflammatory cytokines, and improving clinical outcomes. Plasma exchange aims to eliminate pathogenic autoantibodies and proinflammatory cytokines, and is used in diverse immune-mediated neurologic conditions. However, its effect in Enterovirus-71 infections is unknown. We report three cases of severe Enterovirus-71 neurological disease treated with plasma exchange during an outbreak in Catalonia (Spain) in 2016. We observed a striking improvement in all three patients within 48 h of starting plasma exchange. Patients received four to six sessions every other day. Good outcomes were confirmed at the 1-year follow-up visit. Our observations suggest that plasma exchange is an effective complementary therapy for severe Enterovirus-71 neurological disease.

Background: Dementia with Lewy bodies (DLB) is a heterogeneous disease in which clinical presentation, symptoms, and evolution widely varies between patients.Objective: To investigate the existence of clinical subtypes in DLB based on the initial clinical presentation.Methods: 81 patients with a clinical diagnosis of probable DLB were consecutively included. All patients underwent a neurological evaluation including a structured questionnaire about neuropsychiatric symptoms and sleep, an assessment of motor impairment (Unified Parkinson Disease Rating Scale subscale III), and a formal neuropsychological evaluation. Onset of core symptoms (hallucinations, parkinsonism, and fluctuations) and dementia were systematically reviewed from medical records. We applied a K-means clustering method based on the initial clinical presentation.Results: Cluster analysis yielded three different groups. Patients in cluster I (cognitive-predominant, n = 46) presented more frequently with cognitive symptoms (95.7%, n = 44, p < 0.001), and showed a longer duration from onset to DLB diagnosis (p < 0.001) than the other clusters. Patients in cluster II (neuropsychiatric-predominant, n = 22) were older at disease onset (78.1±5 versus 73.6±6.1 and 73.6±4.2 in clusters I and III, respectively, both p < 0.01), presented more frequently with psychotic symptoms (77.3%, n = 17), and had a shorter duration until the onset of hallucinations (p < 0.001). Patients in cluster III (parkinsonism-predominant, n = 13) showed a shorter time from onset to presence of parkinsonism (p < 0.001) and dementia (0.008).Conclusions: Three clinical subtypes of DLB can be defined when considering the differential initial presentations. The proposed subtypes have distinct clinical profiles and progression patterns. [ABSTRACT FROM AUTHOR]- Published

[Objective] To describe the clinical characteristics and outcomes in patients with refractory myasthenia gravis (MG) and to determine the effectiveness and side effects of the drugs used for their treatment., [Methods] This observational retrospective cross-sectional multicenter study was based on data from the Spanish MG Registry (NMD-ES). Patients were considered refractory when their MG Foundation of America post-interventional status (MGFA-PIS) was unchanged or worse after corticosteroids and two or more other immunosuppressive agents. Clinical and immunologic characteristics of drug-refractory patients, efficiency and toxicity of drugs used, and outcome (MGFA-PIS) at end of follow-up were studied., [Results] We included 990 patients from 15 hospitals. Eighty-four patients (68 of 842 anti-acetylcholine receptor [AChR], 5 of 26 anti-muscle-specific tyrosine kinase [MusK], 10 of 120 seronegative, and 1 of 2 double-seropositive patients) were drug refractory. Drug-refractory patients were more frequently women (p, [Interpretation] In this study, 8.5% of MG patients were drug-refractory. New more specific drugs are needed to treat drug-refractory MG patients., This work was funded by the Instituto de Salud Carlos III through the project PI19/01774 (cofunded by the European Union ERDF), PI I.

- Abstract
Background and Objectives: To study the clinical and laboratory features of antineurofascin-155 (NF155)-positive autoimmune nodopathy (AN)., Methods: Patients with anti-NF155 antibodies detected on routine immunologic testing were included. Clinical characteristics, treatment response, and functional scales (modified Rankin Scale [mRS] and Inflammatory Rasch-built Overall Disability Scale [I-RODS]) were retrospectively collected at baseline and at the follow-up. Autoantibody and neurofilament light (NfL) chain levels were analyzed at baseline and at the follow-up., Results: Forty NF155+ patients with AN were included. Mean age at onset was 42.4 years. Patients presented with a progressive (75%), sensory motor (87.5%), and symmetric distal-predominant weakness in upper (97.2%) and lower extremities (94.5%), with tremor and ataxia (75%). Patients received a median of 3 (2-4) different treatments in 46 months of median follow-up. Response to IV immunoglobulin (86.8%) or steroids (72.2%) was poor in most patients, whereas 77.3% responded to rituximab. HLA-DRB1*15 was detected in 91.3% of patients. IgG4 anti-NF155 antibodies were predominant in all patients; anti-NF155 titers correlated with mRS within the same patient ( r = 0.41, p = 0.004). Serum NfL (sNfL) levels were higher in anti-NF155+ AN than in healthy controls (36.47 vs 7.56 pg/mL, p < 0.001) and correlated with anti-NF155 titers ( r = 0.43, p = 0.001), with I-RODS at baseline ( r = -0.88, p < 0.001) and with maximum I-RODS achieved ( r = -0.58, p = 0.01). Anti-NF155 titers and sNfL levels decreased in all rituximab-treated patients., Discussion: Anti-NF155 AN presents a distinct clinical profile and good response to rituximab. Autoantibody titers and sNfL are useful to monitor disease status in these patients. The use of untagged-NF155 plasmids minimizes the detection of false anti-NF155+ cases., Classification of Evidence: This study provides Class IV evidence that anti-NF155 antibodies associate with a specific phenotype and response to rituximab., (Copyright © 2021 The Author(s).
