Country-report pattern corrections of new cases allow accurate 2-week predictions of COVID-19 evolution with the Gompertz model.

Accurate short-term predictions of COVID-19 cases with empirical models allow Health Officials to prepare for hospital contingencies in a two-three week window given the delay between case reporting and the admission of patients in a hospital. We investigate the ability of Gompertz-type empiric models to provide accurate prediction up to two and three weeks to give a large window of preparation in case of a surge in virus transmission. We investigate the stability of the prediction and its accuracy using bi-weekly predictions during the last trimester of 2020 and 2021. Using data from 2020, we show that understanding and correcting for the daily reporting structure of cases in the different countries is key to accomplish accurate predictions. Furthermore, we found that filtering out predictions that are highly unstable to changes in the parameters of the model, which are roughly 20%, reduces strongly the number of predictions that are way-off. The method is then tested for robustness with data from 2021. We found that, for this data, only 1-2% of the one-week predictions were off by more than 50%. This increased to 3% for two-week predictions, and only for three-week predictions it reached 10%.

Inhibidores de la proproteína convertasa subtilisina/kexina tipo 9 (iPCSK9) en la prevención secundaria de episodios vasculares en pacientes con ictus isquémico: Documento de consenso y aplicaciones prácticas / Proprotein convertase subtilisin/kexin type 9 inhibitors in secondary prevention of vascular events in patients with stroke: Consensus document and practice guidance

Introducción: Los pacientes, tras un ictus o un ataque isquémico transitorio, presentan un riesgo muy elevado de sufrir nuevos episodios vasculares. La reducción del nivel de colesterol unido a lipoproteínas de baja densidad (cLDL) reduce la incidencia de nuevos episodios, si bien una proporción importante de pacientes no alcanza los objetivos terapéuticos recomendados con los tratamientos hipolipemiantes actuales. El objetivo de este documento de consenso es actualizar el papel de los inhibidores de la proproteína convertasa subtilisina/kexina tipo 9 (iPCSK9; alirocumab y evolocumab) en la prevención secundaria de episodios vasculares en pacientes con ictus isquémico previo. Métodos: Se realizó una revisión bibliográfica para identificar las principales evidencias sobre el uso de iPCSK9 en estos pacientes y los objetivos terapéuticos recomendados de cLDL. Los resultados se discutieron en 2 reuniones de consenso, que constituyeron la base para la elaboración del documento. Conclusiones: Los iPSCSK9 son eficaces en la reducción del riesgo vascular en prevención secundaria y, específicamente, evolocumab ha demostrado esta reducción en pacientes con ictus isquémico previo. Ambos fármacos han demostrado un buen perfil de seguridad, incluso en pacientes que alcanzaron un nivel de cLDL < 20 mg/dL. En este sentido, en el subestudio de episodios neurocognitivos con evolocumab no se observó ninguna señal de empeoramiento de la función cognitiva en pacientes con nivel muy bajo de cLDL. Con base en estas evidencias, en el documento se presentan recomendaciones prácticas sobre el uso de iPCSK9 para la prevención secundaria y seguimiento de episodios vasculares en pacientes con ictus isquémico previo.

Introduction: Patients with history of stroke or transient ischaemic attack present considerable risk of future vascular events. Reducing levels of low-density lipoprotein (LDL) cholesterol decreases the incidence of new vascular events, although in a substantial number of patients, the currently available lipid-lowering therapies fail to achieve the therapeutic goals recommended in clinical guidelines. The aim of this consensus statement is to provide updated information on the role of the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors alirocumab and evolocumab in the secondary prevention of vascular events in patients with history of ischaemic stroke. Methods: A literature review was performed to identify the main evidence on the use of PCSK9 inhibitors in these patients and the recommended therapeutic targets of LDL cholesterol. The results were discussed in 2 consensus meetings that constituted the basis for the drafting of the document. Conclusions: PCSK9 inhibitors are effective in reducing vascular risk in secondary prevention; evolocumab specifically has achieved this reduction in patients with history of ischaemic stroke. Moreover, both alirocumab and evolocumab present good safety profiles, even in patients achieving LDL cholesterol levels < 20 mg/dL, and no signs of cognitive impairment have been observed in patients treated with evolocumab who achieved very low levels of LDL cholesterol. In the light of this evidence, we provide practical recommendations about the use of PCSK9 inhibitors in secondary prevention of vascular events in patients with history of ischaemic stroke and follow-up of these patients.

Epithelioma cuniculatum of the sole of the foot mimicking an infection.

Epithelioma cuniculatum is characterized as a slow growing lesion on the sole of the foot. A diagnosis is usually delayed by a low clinical suspicion and misdirection due to its similarity to an infection. This tumor rarely metastasize but a local invasion of adjacent soft tissues is common, requiring ample surgical resection or even amputation in advanced cases. We report a case a 76-year-old patient with a 5-year-old lesion on the sole of the foot, which was originally treated as a wart without improvement while the lesion slowly evolved. The patient was referred to our center with a diagnosis of chronic osteomyelitis. An excisional biopsy revealed an invasive keratinizing squamous carcinoma. In this advanced phase of the disease the only possible treatment was a Syme amputation.

El epitelioma cuniculatum se caracteriza por una lesión de crecimiento lento en la planta del pie cuyo diagnóstico suele retrasarse por la baja sospecha clínica y por su similitud con una infección. Este tumor raramente metastatiza, pero es común que produzca una invasión local a los tejidos blandos adyacentes, requiriendo una amplia resección quirúrgica o incluso una amputación en casos avanzados. Presentamos un caso de un paciente de 76 años con una lesión de 5 años de edad en la planta del pie, que originalmente fue tratada como una verruga plantar común sin mejoría, mientras que la lesión evolucionó lentamente. El paciente fue remitido a nuestro centro con un diagnóstico de osteomielitis crónica. Una biopsia excisional reveló un carcinoma escamoso queratinizante invasivo. En esta fase avanzada de la enfermedad el único tratamiento posible fue una amputación de Syme.

Acute symptomatic seizures and epilepsy after mechanical thrombectomy. A prospective long-term follow-up study.

INTRODUCTION: New treatments for acute ischaemic stroke, such as mechanical thrombectomy, can achieve reperfusion of large ischaemic tissue. Some studies have suggested that reperfusion therapies can increase the risk of suffering acute symptomatic seizure (ASS) and poststroke epilepsy (PSE). The aim of the study was to determine the incidence of ASS and PSE in patients undergoing thrombectomy, and related factors. PATIENTS AND METHODS: This was a retrospective single-centre study including patients with ischaemic stroke and NIHSS> 8 treated with thrombectomy with a follow-up ≥5 years. We evaluated several epidemiological, radiological, clinical and electroencephalographic variables. RESULTS: Of the 344 included patients, 21 (6.1%) presented ASS, 53 (15.40%) died in the acute phase, and 13 (4.46%) died during the first year. The degree of reperfusion (p 0.029), advanced age (p 0.035), and haemorrhagic transformation (p 0.038) increased the risk of suffering ASS, with degree of reperfusion being an independent factor, OR 2.02 (1.21-4.64). The incidence of PSE was 4.12% in the first year, 3.72% in the second, and 1.61% in the fifth. The accumulated incidence at 5 years was 8.93%. Related risk factor for suffering PSE was ASS (p < 0.001), yielding an OR value of 2.00 (1.28-3.145). CONCLUSIONS: Thrombectomy doesn´t increase the risk of ASS. A higher percentage of reperfusion, advanced age, and haemorrhagic transformation are associated with an increased risk of ASS. ASS is a risk factor for suffering PSE. In terms of mortality, having suffered ASS and/or PSE does not increase acute or long-term mortality.

Neurologic Involvement in COVID-19: Cause or Coincidence? A Neuroimaging Perspective.

The rapid spread of the coronavirus disease 2019 (COVID-19) pandemic has shaken hospitals worldwide. Some authors suggest that neurologic involvement could further complicate the disease. This descriptive study is a cross-sectional review of 103 patients diagnosed with COVID-19 who underwent neuroimaging (of a total of 2249 patients with COVID-19 in our center). Analyzed variables were neurologic symptoms and acute imaging findings. The most frequent symptoms that motivated neuroimaging examinations were mild nonfocal neurologic symptoms, code stroke (refers to patients presenting with signs and symptoms of stroke whose hyperacute assessment and care is prioritized), focal neurologic symptoms, postsedation encephalopathy, and seizures. No cases of encephalitis or direct central nervous system involvement were detected. Thirteen patients presented with acute ischemic events, and 7, with hemorrhagic events; however, most reported multiple vascular risk factors. Despite the large cohort of patients with COVID-19, we found a large number of symptomatic patients with negative neuroimaging findings, and no conclusions can be drawn concerning concrete associations between neuroimaging and COVID-19.

The neurologist's approach to cerebral infarct and transient ischaemic attack in patients receiving anticoagulant treatment for non-valvular atrial fibrillation: ANITA-FA study.

BACKGROUND AND PURPOSE: The aim of this study was to describe the clinical and epidemiological characteristics of acute ischaemic stroke (AIS) in patients with atrial fibrillation (AF) previously treated with oral anticoagulants (OACs) according to the type of OAC prescribed. Also, to analyze the outcomes of the patients and the therapeutic approach adopted by the neurologist in the acute phase and for secondary prevention. METHODS: We performed a multicenter, observational study based on prospective registries. We included patients with AF treated with OACs admitted for AIS over a 1-year period. Detailed clinical data and functional outcome at 3 months (modified Rankin Scale score) were collected. Patients were divided into two groups according to their pre-AIS anticoagulant therapy: vitamin K antagonists (AIS-VKA) and direct-acting OACs (AIS-DOAC). RESULTS: We recruited 1240 patients (80.4% AIS-VKA and 19.6% AIS-DOAC). In the AIS-DOAC group, transient ischaemic attack was more frequent (18.1% vs. 10.8%; P = 0.001), symptomatic hemorrhagic transformation was less frequent (1.6% vs. 4.6%; P = 0.035) and hospital stay was shorter (median 6 vs. 7 days; P = 0.03). Intravenous thrombolysis was more commonly used in AIS-VKA (9.2% vs. 1.6%; P < 0.001). There were no differences between the groups with respect to mechanical thrombectomy, mortality and modified Rankin Scale score at 3 months. At 3 months, 54% of patients required a DOAC as antithrombotic treatment for secondary prevention. CONCLUSIONS: Patients with AF treated with DOACs who experienced AIS more frequently had transient symptoms (transient ischaemic attack), less symptomatic hemorrhagic transformation and a shorter mean stay than those treated with VKAs. Most patients who had been previously anticoagulated with AIS received long-term treatment with DOACs.

Factores asociados al mal control de la anticoagulación con antivitaminaK en pacientes con fibrilación auricular no valvular atendidos en consultas de Medicina Interna y Neurología. Estudio ALADIN / Factors associated with poor anticoagulation control with vitaminK antagonists among outpatients attended in Internal Medicine and Neurology. The ALADIN study

Objetivo: Identificar los factores asociados con el mal control de la anticoagulación con antagonistas de la vitaminaK (AVK) en pacientes con fibrilación auricular no valvular (FANV) atendidos en consultas de Neurología y Medicina Interna de España. Métodos: Estudio transversal, multicéntrico, anidado en el estudio ALADIN, de sujetos con FANV, tratados con AVK, atendidos en consultas de Medicina Interna o Neurología de España. El grado de control de la anticoagulación se estudió mediante el método directo y el de Rosendaal, considerando los 6meses previos a la inclusión. Resultados: De los 1.337 pacientes incluidos en ALADIN, 750 estaban tratados con AVK, con información completa sobre el INR de los últimos 6meses en 383 pacientes. Las puntuaciones medias del índice de Charlson, CHADS2, CHA2DS2-VASc y HAS-BLED fueron 1,94±1,54; 3,10±1,26; 4,63±1,54 y 2,20±0,90, respectivamente. El 46,2% y el 47,0% de los pacientes presentaban un control adecuado de la anticoagulación por los métodos directo y Rosendaal, respectivamente. El control inadecuado de la anticoagulación se asoció por el método directo con diabetes (OR: 2,511; IC95%: 1,144-5,659), antecedentes de INR inestable (OR: 35,371; IC95%: 15,058-83,083) y la realización de >6 controles en los últimos 6meses (OR: 4,747; IC95%: 2,094-10,759), y por el método de Rosendaal, con los antecedentes de INR inestable (p<0,001) y con HAS-BLED (OR: 3,991; IC95%: 2,520-6,319). Conclusiones: Pese al alto riesgo tromboembólico, sólo estaban bien controlados algo más de la mitad. Los factores asociados al mal control de la anticoagulación fueron la diabetes, INR inestable, >6 controles de INR y el HAS-BLED

Objective: To identify factors associated with poor anticoagulation control with vitaminK antagonists (VKA) among outpatients with nonvalvular atrial fibrillation (NVAF) attended in Neurology and Internal Medicine in Spain. Methods: Cross-sectional and multicenter study, from the ALADIN database, of outpatients with NVAF treated with VKA and attended in Internal Medicine and Neurology in Spain. Rates of anticoagulation control were determined with the direct and Rosendaal methods, considering data from the 6months before the inclusion. Results: Out of 1,337 patients included in the ALADIN study, 750 were taking VKA, and complete information about INR values in the last 6months was available in 383 patients. Mean scores of Charlson Index, CHADS2, CHA2DS2-VASc and HAS-BLED were 1.94±1.54; 3.10±1.26; 4.63±1.54, and 2.20±0.90, respectively. 46.2% and 47.0% of patients had an adequate anticoagulation control according to the direct and Rosendaal methods, respectively. Inadequate anticoagulation control according to the direct method was associated with diabetes (OR: 2.511; 95%CI: 1.144-5.659), prior labile INR (OR: 35.371; 95%CI: 15.058-83.083) and the determination of >6INR controls in the last 6months (OR: 4.747; 95%CI: 2.094-10.759), and according to the Rosendaal method, with prior labile INR (P<.001) and HAS-BLED score (OR: 3.991; 95%CI: 2.520-6.319). Conclusions: Despite the high thromboembolic risk, only a little more than a half of patients were well controlled. Factors associated with poor anticoagulation control were diabetes, labile INR, >6INR controls and HAS-BLED

[Clinical profile and satisfaction with anticoagulated treatment in patients with non-valvular atrial fibrillation attended in Internal Medicine and Neurology departments of Spain]. / Perfil clinico y satisfaccion con el tratamiento anticoagulante en pacientes con fibrilacion auricular no valvular atendidos en consultas de medicina interna y neurologia de España.

AIM: To determine the clinical profile, management of anticoagulant treatment and satisfaction related to anticoagulation in outpatients with nonvalvular atrial fibrillation attended in Neurology or Internal Medicine departments of Spain. PATIENTS AND METHODS: Cross-sectional and multicenter study, in which 1,337 outpatients were included. Patients fulfilled ACTS, SAT-Q and EQ-5D questionnaires. RESULTS: 865 patients (64.7%) were recruited from Neurology department and 472 (35.3%) from Internal Medicine department. Those patients attended in Internal Medicine department were older and had more frequently hypertension, diabetes, heart failure, renal insufficiency and peripheral artery disease. Those patients attended in Neurology department had more commonly prior stroke. Overall, CHADS2 score was 3.2 ± 1.3, CHA2DS2-Vasc 4.8 ± 1.5 and HAS-BLED 2.0 ± 0.9. All scores were higher in those patients attended in Neurology department. Globally, 56.1% of patients were taking vitamin K antagonists, more commonly in Internal Medicine department. The adequate percent of time in therapeutic range was 47% (Rosendaal), without significant differences between groups. Satisfaction with oral anticoagulation was high in both groups, but higher in those attended in Neurology department, and higher in those individuals taking direct oral anticoagulants compared with vitamin K antagonists. CONCLUSIONS: Although there were some differences in the clinical profile of patients with atrial fibrillation attended in Neurology or Internal Medicine departments, all of them had many comorbidities and a high thromboembolic risk. Despite INR control was poor, the most common oral anticoagulant used were vitamin K antagonists. Satisfaction related to oral anticoagulation was high.

TITLE: Perfil clinico y satisfaccion con el tratamiento anticoagulante en pacientes con fibrilacion auricular no valvular atendidos en consultas de medicina interna y neurologia de España.Objetivo. Determinar el perfil clinico, el manejo del tratamiento anticoagulante y la satisfaccion relacionada con la anticoagulacion en pacientes con fibrilacion auricular no valvular atendidos en consultas de neurologia o medicina interna de España. Pacientes y metodos. Estudio prospectivo, transversal y multicentrico en el que se incluyo a 1.337 pacientes, que completaron los cuestionarios Anti-Clot Treatment Scale, Self-Assessment of Treatment Questionnaire y EuroQol-5 dimensions. Resultados. 865 pacientes (64,7%) provenian de consultas de neurologia, y 472 (35,3%), de medicina interna. Los atendidos en medicina interna eran mayores, tenian mas hipertension, diabetes, insuficiencia cardiaca, insuficiencia renal y arteriopatia periferica. Los pacientes atendidos en neurologia tenian mas antecedentes de ictus. Globalmente, la escala CHADS2 fue 3,2 ± 1,3; CHA2DS2Vasc, 4,8 ± 1,5, y HAS-BLED, 2,0 ± 0,9, y las puntuaciones mas altas fueron en neurologia. El 56,1% tomaba antagonistas de la vitamina K, lo que era mas comun en medicina interna. El porcentaje de tiempo en rango terapeutico adecuado fue del 47% (Rosendaal), sin diferencias entre los grupos. La satisfaccion con el tratamiento anticoagulante oral fue elevada en ambos grupos, aunque mayor en los sujetos atendidos en neurologia, y mayor con los anticoagulantes orales de accion directa que con los antagonistas de la vitamina K. Conclusiones. Aunque existieron ciertas diferencias en el perfil clinico de los pacientes con fibrilacion auricular atendidos en neurologia o medicina interna, todos presentaban multiples comorbilidades y un riesgo tromboembolico elevado. A pesar de que el control del indice internacional normalizado fue pobre, el anticoagulante oral mas empleado fueron los antagonistas de la vitamina K. La satisfaccion con el tratamiento anticoagulante oral fue alta.

Ictus isquémico en pacientes en tratamiento anticoagulante por vía oral / Ischaemic stroke in patients treated with oral anticoagulants

Introducción: Los ictus cardioembólicos tienen peor pronóstico. Su prevención se basa en el tratamiento anticoagulante por vía oral (ACO), cuya principal complicación es el sangrado y, en ocasiones, su ineficacia. Pacientes y métodos: Se ha revisado retrospectivamente a 1.014 pacientes consecutivos que presentaron ictus isquémico entre 2011 y 2013. De ellos, hemos analizado a los 107 pacientes en tratamiento con ACO en el momento del ictus, con especial atención a su etiología, evolución y valor del INR en la fase aguda. Resultados: La edad media ± desviación estándar fue de 71,9 ± 10 años. Tomaba ACO desde hacía 5,9 ± 5,5 años el 98,1% por cardiopatía. Setenta y siete pacientes (72%) tenían INR < 2 y 30 (28%) un INR ≥ 2. Se encontraban en rango terapéutico 9 pacientes (8,4%). La etiología según TOAST fue cardioembólica en el 88,8% y aterotrombótica en el 1,9%. Se suspendió la anticoagulación en 48 pacientes (44,9%): 24 por transformación hemorrágica, 23 por infarto extenso y uno por endarterectomía. Se reintrodujo en 24 de ellos (50%), a los 36 días de media; en los restantes, no fue posible por fallecimiento o secuelas severas. En 9 pacientes (18,7% de potenciales candidatos) se iniciaron nuevos ACO (NACO). La evolución a los 3 meses fue mejor si el INR en la fase aguda > 1,7 respecto al INR ≤ 1,7 (mRS 0-2: 62% vs. 30,8% y fallecimiento 10% vs. 38.4%; p = 0,0004). Conclusiones: Algunos pacientes con ACO presentan ictus isquémicos, en general cardioembólicos, especialmente si el INR es infraterapéutico. Se pueden reintroducir ACO sin complicaciones, siendo el uso de NACO todavía escaso. A pesar de su ineficacia, la evolución es mejor si INR > 1,7 al inicio del ictus

Introduction: Cardioembolic stroke is associated with poorer outcomes. Prevention is based on oral anticoagulant (OAC) therapy. Haemorrhage is the main complication of OACs, which are sometimes ineffective. Patients and methods: We retrospectively reviewed 1014 consecutive patients who suffered an ischaemic stroke between 2011 and 2013, analysing those who were receiving OAC treatment at stroke onset (107 patients in total) with special attention to aetiology, outcomes, and INR value in the acute phase. Results: The mean age (SD) was 71.9 (10) years. Patients had been treated with OACs for 5.9 (5.5) years; 98.1% of them were being treated for heart disease. INR was <2 in 77 patients (72%), and 30 patients (28%) had an INR≥2. Nine patients (8.4%) had INR values within the therapeutic range. According to TOAST classification criteria, 88.8% of strokes were cardioembolic and 1.9% were atherothrombotic. Anticoagulation therapy was discontinued in 48 patients (44.9%) due to haemorrhagic transformation (24 patients), extensive infarction (23), or endarterectomy (1). Therapy was resumed in 24 patients (50%) after a mean lapse of 36 days. This was not possible in the remaining patients because of death or severe sequelae. New OACs (NOACs) were prescribed to 9 patients (18.7% of all potential candidates). At 3 months, patients with INR>1.7 in the acute phase exhibited better outcomes than patients with INR≤1.7 (mRS 0-2 in 62% vs 30.8%; death in 10% vs 38.4%; P=.0004). Conclusions: Some patients taking OACs suffer ischaemic strokes that are usually cardioembolic, especially if INR is below the therapeutic range. OACs can be resumed without complications, and NOACs are still underused. Despite cases in which treatment is ineffective, outcomes are better when INR is above 1.7 at stroke onset
