Propuesta de intervención sobre un incunable perteneciente a la Biblioteca Histórica Marqués de Valdecilla de la UCM
En el presente trabajo se desarrolla una propuesta de restauración y conservación acerca de un incunable perteneciente a la Biblioteca Histórica Marqués de Valdecilla de la UCM, más concretamente el ejemplar titulado “Cosmographia”, escrito originalmente por Claudio Ptolomeo. El libro en cuestión es una reedición alemana realizada en el año 1486 por Dominus Nicolaus Germanus, está basada en la traducción del texto al latín que llevó a cabo Jacobus Angelus. Los contenidos que aparecen reflejados aportan información sobre las coordenadas de aproximadamente 8.000 lugares del mundo, los cuales se representan en varios mapas regionales y un mapamundi.
El estado de deterioro que presenta el libro está provocado, en su mayor parte, por los refuerzos de pergamino adheridos al soporte de la parte correspondiente a los mapas, fruto de una intervención histórica. Tras analizar el valor cultural que posee dicha intervención, se ha optado por su mantenimiento y no por su eliminación, puesto que poseen una función documental y didáctica importante. Además, existe un ejemplar prácticamente idéntico en la misma biblioteca, el cual esta digitalizado. Así pues, los tratamientos de restauración propuestos están destinados a la preservación integral de todos los elementos que conforman el libro, llevando a cabo las funciones de consolidación necesarias para frenar el deterioro producido por los refuerzos mencionados en el párrafo anterior. Finalmente, se han analizado las medidas de conservación tomadas en la biblioteca con el fin de valorar su adecuación para la correcta conservación del libro
Cutaneous Allodynia in Migraine: A Narrative Review
Cutaneous allodynia; Risk factors; TreatmentAlodinia cutánea; Factores de riesgo; TratamientoAlodínia cutània; Factors de risc; TractamentObjective: In the present work, we conduct a narrative review of the most relevant literature on cutaneous allodynia (CA) in migraine.
Background: CA is regarded as the perception of pain in response to non-noxious skin stimulation. The number of research studies relating to CA and migraine has increased strikingly over the last few decades. Therefore, the clinician treating migraine patients must recognize this common symptom and have up-to-date knowledge of its importance from the pathophysiological, diagnostic, prognostic and therapeutic point of view.
Methods: We performed a comprehensive narrative review to analyze existing literature regarding CA in migraine, with a special focus on epidemiology, pathophysiology, assessment methods, risk for chronification, diagnosis and management. PubMed and the Cochrane databases were used for the literature search.
Results: The prevalence of CA in patients with migraine is approximately 60%. The mechanisms underlying CA in migraine are not completely clarified but include a sensitization phenomenon at different levels of the trigemino-talamo-cortical nociceptive pathway and dysfunction of brainstem and cortical areas that modulate thalamocortical inputs. The gold standard for the assessment of CA is quantitative sensory testing (QST), but the validated Allodynia 12-item questionnaire is preferred in clinical setting. The presence of CA is associated with an increased risk of migraine chronification and has therapeutic implications.
Conclusions: CA is a marker of central sensitization in patients with migraine that has been associated with an increased risk of chronification and may influence therapeutic decisions

Dysautonomia in COVID-19 Patients: A Narrative Review on Clinical Course, Diagnostic and Therapeutic Strategies
IntroductionOn March 11, 2020, the World Health Organization sounded the COVID-19 pandemic alarm. While efforts in the first few months focused on reducing the mortality of infected patients, there is increasing data on the effects of long-term infection (Post-COVID-19 condition). Among the different symptoms described after acute infection, those derived from autonomic dysfunction are especially frequent and limiting. ObjectiveTo conduct a narrative review synthesizing current evidence of the signs and symptoms of dysautonomia in patients diagnosed with COVID-19, together with a compilation of available treatment guidelines. ResultsAutonomic dysfunction associated with SARS-CoV-2 infection occurs at different temporal stages. Some of the proposed pathophysiological mechanisms include direct tissue damage, immune dysregulation, hormonal disturbances, elevated cytokine levels, and persistent low-grade infection. Acute autonomic dysfunction has a direct impact on the mortality risk, given its repercussions on the respiratory, cardiovascular, and neurological systems. Iatrogenic autonomic dysfunction is a side effect caused by the drugs used and/or admission to the intensive care unit. Finally, late dysautonomia occurs in 2.5% of patients with Post-COVID-19 condition. While orthostatic hypotension and neurally-mediated syncope should be considered, postural orthostatic tachycardia syndrome (POTS) appears to be the most common autonomic phenotype among these patients. A review of diagnostic and treatment guidelines focused on each type of dysautonomic condition was done. ConclusionSymptoms deriving from autonomic dysfunction involvement are common in those affected by COVID-19. These symptoms have a great impact on the quality of life both in the short and medium to long term. A better understanding of the pathophysiological mechanisms of Post-COVID manifestations that affect the autonomic nervous system, and targeted therapeutic management could help reduce the sequelae of COVID-19, especially if we act in the earliest phases of the disease
Gestió cinegètica del Rupicapra pyrenaica pyrenaica a la Reserva Nacional de Caça del Cadí : vedat de caça privat, la cara oposada de la Reserva Nacional de Caça del Cadí
La població d'isards es troba en quatre zones del territori de la Península Ibèrica, essent Catalunya una d'elles, concretament en la major part del Pirineu Axial i algunes zones del Prepirineu. La Reserva Nacional de Caça del Cadí es va crear l'any 1966 principalment per la seva gestió i protecció de l'espècie amb la finalitat d'assegurar la viabilitat d'aquesta. Des de la implantació d'aquesta figura de gestió cinegètica, la població ha presentat sempre una tendència positiva al creixement exceptuant l'any 2004 on hi va haver-hi l'afectació d'una malaltia epizoòtia anomenada "virus de la frontera". Actualment la població torna a presentar una evolució positiva després de l'aturada de l'activitat cinegètica durant 4 anys. Entorn a la gestió que duu a terme l'administració hi ha una gran controvèrsia d'interessos i beneficis econòmics entre els diferents actors que conformen l'activitat cinegètica. Actualment, s'observa una tendència dels propietaris a la necessitat de disgregar-se de la Reserva creant vedats de caça privats per tal d'augmentar el benefici propi entorn l'activitat cinegètica de l'espècie
Grado de cumplimiento terapéutico a los tres meses en pacientes con migraña
Introducción
La adhesión al tratamiento preventivo oral (TPO) en la migraña se ve frecuentemente comprometida. El objetivo fue conocer el grado de adhesión al TPO en pacientes con migraña a los tres meses.
Pacientes y métodos
Estudio multicéntrico observacional de pacientes diagnosticados de migraña episódica o crónica (criterios de la Clasificación Internacional de Cefaleas, tercera edición) en los que se iniciaba TPO. Se recogieron datos demográficos (edad, género, nivel estudios, estado civil) y de enfermedad (número de ataques, puntuación en las escalas Headache Impact Test-6 y Migraine Disability Assessment Scale). A los tres meses se pasó la escala de Morisky Green, que diferencia niveles de adhesión: excelente (0), moderada (1-2) y baja (3-4).
Resultados
Participaron 100 pacientes, un 87% mujeres de 42 ± 13 años, el 14% con migraña crónica. El 53,2% comenzaba su primer TPO. Se iniciaron betabloqueantes en el 23,2%, antidepresivos tricíclicos en el 35,4%, flunaricina en el 21,2%, neuromoduladores en el 19,2% y antihipertensivos en el 1%. El 56% presentaba discapacidad grave y el 79,5%, impacto muy grave. La adhesión a los tres meses fue excelente en el 41,8%, moderada en el 28,6% y baja en el 29,6%. El motivo más frecuente de discontinuación fueron los efectos adversos (44%). Se encontró una relación significativa entre adhesión excelente y estado civil soltero (p = 0,046), y entre adhesión baja y efectos adversos (p = 0,009). No se encontraron diferencias significativas entre los TPO empleados y el grado de adhesión ni con el resto de variables estudiadas.
Conclusiones
Aunque nuestros resultados son mejores que los publicados en la bibliografía, consideramos que la adhesión terapéutica en nuestro medio es baja y es prioritario educar a nuestros pacientes en este sentido
Increasing trend of antimicrobial resistance in Shigella associated with MSM transmission in Barcelona, 2020-21 : outbreak of XRD Shigella sonnei and dissemination of ESBL-producing Shigella flexneri
Several countries have recently reported the detection of ESBL-producing Shigella sonnei associated with transmission among MSM. In a previous study by our group, 2.8% of Shigella spp. obtained from MSM in Barcelona between 2015 and 2019 were ESBL producers. To describe and characterize the emerging ESBL-producing Shigella spp. associated with sexual transmission among MSM detected from 2020 to 2021 in Barcelona, elucidating their connectivity with contemporaneous ESBL-producing Shigella spp. from other countries. From 2020 to 2021, we identified that among MSM, 68% of S. sonnei were XDR harbouring bla and 14% of Shigella flexneri were MDR harbouring bla . WGS analysis showed that the ESBL-producing S. sonnei were part of a monophyletic cluster, which included isolates responsible for the prolonged outbreak occurring in the UK. Our data also reveal the first emergence and clonal dissemination of ESBL-producing and fluoroquinolone-resistant S. flexneri 2a among MSM. We report an increasing trend of antimicrobial resistance in Shigella spp. among MSM in Barcelona since 2021, mainly as a consequence of the dissemination of XDR ESBL-producing S. sonnei, previously reported in the UK. These results highlight the importance of international collaborative surveillance of MDR/XDR S. sonnei and S. flexneri for rapid identification of their emergence and the prevention of the transmission of these pathogens

Near-normal aerobic capacity in long-term survivors after lung transplantation
Lung transplant; Survivors; Aerobic capacityTrasplantaments de pulmó; Supervivents; Capacitat aeròbicaTrasplantes de pulmón; Supervivientes; Capacidad aeróbicaThe clinical course of lung transplantation (LT) is diverse: some patients present chronic lung allograft dysfunction (CLAD) and progressive decline in pulmonary function, but others maintain normal spirometric values and active lives. Objectives The aim of this study was to elucidate whether long-term LT survivors with normal spirometry achieve normal exercise capacity, and to identify predictive factors of exercise capacity. Methods This was a cross-sectional multicentre study, where bilateral LT recipients who survived at least 10 years after LT, with normal spirometry, no diagnosis of CLAD and modified Medical Research Council dyspnoea degree ≤2 underwent cardiopulmonary exercise testing (CPET). Results 28 LT recipients were included with a mean±sd age of 48.7±13.6 years. Oxygen uptake (V′O2) had a mean±sd value of 21.49±6.68 mL·kg−1·min−1 (75.24±15.6%) and the anaerobic threshold was reached at 48.6±10.1% of the V′O2max predicted. The mean±sd heart rate reserve at peak exercise was 17.56±13.6%. The oxygen pulse increased during exercise and was within normal values at 90.5±19.4%. The respiratory exchange ratio exceeded 1.19 at maximum exercise. The median (25–75th percentile) EuroQol-5D score was 1 (0.95–1), indicating a good quality of life. The median (25–75th percentile) International Physical Activity Questionnaire score was 5497 (4007–9832) MET-min·week−1 with 89% of patients reporting more than 1500 MET-min·week−1. In the multivariate regression models, age, sex and diffusing capacity of the lung for carbon monoxide remained significantly associated with V′O2max (mL·kg−1·min−1); haemoglobin and forced expiratory volume in 1 s were significantly associated with maximum work rate (watts), after adjusting for confounders. Conclusion We report for the first time near-normal peak V′O2 values during CPET and normal exercise capacity in long-term LT recipients without CLAD.Support statement: This study was financed by Instituto de Salud Carlos III (PI13/01076); the European Regional Development Fund (FEDER), FUCAP, Astellas, Novartis and Chiesi.

Oral Anticoagulation and Risk of Symptomatic Hemorrhagic Transformation in Stroke Patients Treated With Mechanical Thrombectomy: Data From the Nordictus Registry
Introduction: We aimed to evaluate if prior oral anticoagulation (OAC) and its type determines a greater risk of symptomatic hemorrhagic transformation in patients with acute ischemic stroke (AIS) subjected to mechanical thrombectomy. Materials and
Methods: Consecutive patients with AIS included in the prospective reperfusion registry NORDICTUS, a network of tertiary stroke centers in Northern Spain, from January 2017 to December 2019 were included. Prior use of oral anticoagulants, baseline variables, and international normalized ratio (INR) on admission were recorded. Symptomatic intracranial hemorrhage (sICH) was the primary outcome measure. Secondary outcome was the relation between INR and sICH, and we evaluated mortality and functional outcome at 3 months by modified Rankin scale. We compared patients with and without previous OAC and also considered the type of oral anticoagulants.
Results: About 1.455 AIS patients were included, of whom 274 (19%) were on OAC, 193 (70%) on vitamin K antagonists (VKA), and 81 (30%) on direct oral anticoagulants (DOACs). Anticoagulated patients were older and had more comorbidities. Eighty-one (5.6%) developed sICH, which was more frequent in the VKA group, but not in DOAC group. OAC with VKA emerged as a predictor of sICH in a multivariate regression model (OR, 1.89 [95% CI, 1.01–3.51], p = 0.04) and was not related to INR level on admission. Prior VKA use was not associated with worse outcome in the multivariate regression model nor with mortality at 3 months.
Conclusions: OAC with VKA, but not with DOACs, was an independent predictor of sICH after mechanical thrombectomy. This excess risk was associated neither with INR value by the time thrombectomy was performed, nor with a worse functional outcome or mortality at 3 months
