RESUMEN
The XVI Post-ECTRIMS meeting was held in Seville on 20 and 21 October 2023, where expert neurologists in multiple sclerosis (MS) summarised the main new developments presented at the ECTRIMS 2023 congress, which took place in Milan from 11 to 13 October. The aim of this article is to summarise the content presented at the Post-ECTRIMS Meeting, in an article in two parts. This second part covers the health of women and elderly MS patients, new trends in the treatment of cognitive impairment, focusing particularly on meditation, neuroeducation and cognitive rehabilitation, and introduces the concept of fatigability, which has been used to a limited extent in MS. The key role of digitalization and artificial intelligence in the theoretically near future is subject to debate, along with the potential these technologies can offer. The most recent research on the various treatment algorithms and their efficacy and safety in the management of the disease is reviewed. Finally, the most relevant data for cladribine and evobrutinib are presented, as well as future therapeutic strategies currently being investigated.

BACKGROUND AND PURPOSE: Open reduction is rarely performed in pediatric supracondylar humerus fractures. However, clear evidence is lacking regarding the optimal open approach to achieve satisfactory results. The anterior approach provides direct visualization of the fracture and excellent exposure to neurovascular structures, although its utilization is less common. The objective of this study was to review the indications, outcomes, and complications associated with the anterior approach for open reduction of these fractures. METHODS: Our protocol was registered at PROSPERO: CRD42023446923. MEDLINE/PubMed, Embase, Web of Science, Clinicaltrials.gov, and Cochrane Library were searched from database inception to search date (December 2023) and screened in duplicate for relevant studies. Data were collected regarding patient demographics, indications for open reduction, Flynn's functional and cosmetic outcomes, and complications. Study quality was assessed using the Methodological Index for Non-Randomized Studies Criteria. RESULTS: A total of 19 studies involving 483 patients were included. One study was classified as Level 2 evidence, ten as Level 3, and eight as Level 4. The mean MINORS score was 13.05±3.47. The primary indication for open reduction was failed closed reduction, observed in 46% of patients. 97.7% and 98.6% of patients achieved Flynn's functional and cosmetic satisfactory results, respectively. The postsurgical neurovascular injury rate was 1.4%. One patient required reintervention. CONCLUSION: The anterior approach is safe and effective for managing pediatric supracondylar humerus fractures requiring open reduction. LEVEL OF EVIDENCE: Systematic review of Level 2-4 evidence studies.

RESUMEN
The XVI Post-ECTRIMS meeting took place in Seville on 20 and 21 October 2023. This meeting was attended by neurologists specialising in multiple sclerosis (MS) from Spain, who shared a summary of the most interesting innovations at the ECTRIMS congress, which had taken place in Milan the previous week. The aim of this article is to summarise new developments related to the pathogenesis, diagnosis and prognosis of MS. The contributions of innate immunity and central nervous system resident cells, including macrophages and microglia in MS pathophysiology and as therapeutic targets were discussed. Compartmentalised intrathecal inflammation was recognised as central to understanding the progression of MS, and the relationship between inflammatory infiltrates and disease progression was highlighted. Perspectives in demyelinating pathologies were reviewed, focusing on neuromyelitis optica and myelin oligodendrocyte glycoprotein antibody-associated disease, highlighting their pathophysiological and diagnostic differences compared to MS. Advances in neuroimaging were also discussed, and especially the analysis of active chronic lesions, such as paramagnetic rim lesions. In the absence of clinical improvements in trials of remyelinating treatments, methodological strategies to optimise the design of future studies were proposed. Breakthroughs in detecting the prodromal phase of MS, the use of biomarkers in body fluids to assess activity, progression and treatment response, and research on progression independent of flares were addressed. The need to define criteria for radiologically isolated syndrome and to clarify the concept was also discussed.
TITLE: XVI Reunión Post-ECTRIMS: revisión de las novedades presentadas en el Congreso ECTRIMS 2023 (I).La XVI edición de la reunión Post-ECTRIMS se celebró los días 20 y 21 de octubre de 2023 en Sevilla. Este encuentro reunió a neurólogos especialistas en esclerosis múltiple (EM) de España, quienes compartieron un resumen de las innovaciones más destacables del congreso ECTRIMS, acontecido en Milán la semana anterior. El objetivo de este artículo es sintetizar las novedades relativas a la patogenia, el diagnóstico y el pronóstico de la EM. Se destacaron las contribuciones de la inmunidad innata y las células residentes del sistema nervioso central, incluyendo macrófagos y microglía, en la patofisiología de la EM y como objetivos terapéuticos. La inflamación intratecal compartimentada se reconoció como fundamental para entender la progresión de la EM, y destaca la relación entre infiltrados inflamatorios y la evolución de la enfermedad. Se revisaron perspectivas en patologías desmielinizantes, enfocadas en la neuromielitis óptica y la enfermedad asociada a anticuerpos contra la glucoproteína de mielina de oligodendrocitos, subrayando sus distinciones patofisiológicas y diagnósticas con la EM. También se abordaron los avances en neuroimagen, especialmente en el análisis de las lesiones crónicas activas, como las lesiones con borde paramagnético. Ante la ausencia de mejoras clínicas en ensayos de tratamientos remielinizantes, se propusieron estrategias metodológicas para optimizar el diseño de futuros estudios. Se abordaron los avances en la detección de la fase prodrómica de la EM, el uso de biomarcadores en fluidos corporales para evaluar la actividad, la progresión y la respuesta al tratamiento, y la investigación sobre la progresión independiente de la actividad de brote. Además, se debatió sobre la necesidad de definir criterios para el síndrome radiológico aislado o precisar su concepto.

The last consensus statement of the Spanish Society of Neurology's Demyelinating Diseases Study Group on the treatment of multiple sclerosis (MS) was issued in 2016. Although many of the positions taken remain valid, there have been significant changes in the management and treatment of MS, both due to the approval of new drugs with different action mechanisms and due to the evolution of previously fixed concepts. This has enabled new approaches to specific situations such as pregnancy and vaccination, and the inclusion of new variables in clinical decision-making, such as the early use of high-efficacy disease-modifying therapies (DMT), consideration of the patient's perspective, and the use of such novel technologies as remote monitoring. In the light of these changes, this updated consensus statement, developed according to the Delphi method, seeks to reflect the new paradigm in the management of patients with MS, based on the available scientific evidence and the clinical expertise of the participants. The most significant recommendations are that immunomodulatory DMT be started in patients with radiologically isolated syndrome with persistent radiological activity, that patient perspectives be considered, and that the term "lines of therapy" no longer be used in the classification of DMTs (> 90% consensus). Following diagnosis of MS, the first DMT should be selected according to the presence/absence of factors of poor prognosis (whether epidemiological, clinical, radiological, or biomarkers) for the occurrence of new relapses or progression of disability; high-efficacy DMTs may be considered from disease onset.

PURPOSE: Atherosclerotic plaques in the brain-supplying arteries are slowly-developing alterations of vascular structures that can lead to neurological impairment due to stenosis and insufficient oxygenation of eloquent brain areas. The aim of this study is to provide detailed demographic information related to the incidence of atherosclerotic plaques in the cerebral arteries. MATERIAL AND METHODS: Forty-eight circles of Willis (21 men, 21 women, mean age: 70.26, six samples unknown) were macroscopically analyzed for length, diameter, and presence of atherosclerotic plaques. Statistical analysis was used to identify potential differences in the locations and frequencies of atherosclerotic plaques in relation to age and sex. RESULTS: The study sample revealed 261 atherosclerotic plaques. The key findings were significant correlations between plaque development and age and between plaque location and age; however, there was no significant sex difference. CONCLUSION: The upper and lower branches of the middle cerebral artery (MCA) were novel locations predisposing to plaque development. A cut-off value at 60 years revealed a significant difference in plaque development and distribution. There were no significant sex differences in the occurrence of atherosclerotic plaques.

OBJECTIVE: The aim of this study was to analyze the activity of the imipenem-relebactam combination (IMI/REL) against a collection of multidrug-resist Enterobacterales, Pseudomonas aeruginosa and Acinetobacter baumannii clinical isolates. METHODS: The study was conducted in two tertiary hospitals in Spain and included 192 clinical isolates of these 3 genera (139 resistant and 53 susceptible to IMI). The MICs for IMI with and without REL (at a fixed concentration of 4 mg/L) were determined by a standard broth microdilution method according to international recommendations. RESULTS: All IMI-susceptible E. coli strains were also susceptible to IMI/REL. Enterobacterales resistant to IMI due to the production of carbapenemases, the MIC50 and MIC90 decreased from 64/256 with IMI to 8/64 mg/L with IMI/REL. This high activity was principally detected among isolates with KPC enzymes. Enterobacterales with class B carbapenemases, P. aeruginosa carrying VIM carbapenemase and A. baumannii strains showed no changes on IMI MIC50 or MIC90 after adding REL. Among P. aeruginosa strains without carbapenemase the MIC for IMI/REL was reduced between 1 to 5 dilutions. CONCLUSIONS: IMI/REL showed high activity against the strains that carry Klebsiella pneumoniae carbapenemase (KPC) and against carbapenem-resistant P. aeruginosa unrelated to the VIM enzyme, mainly AmpC beta lactamase associated with impermeability. Against strains carrying oxacillinase 48 (OXA-48) associated with extended-spectrum beta-lactamase (ESBL), IMI/REL presented activity only slightly better than IMI and had no beneficial effect superior to IMI against A. baumannii.

INTRODUCTION: For more than a decade, after the ECTRIMS Congress, Spain has hosted the Post-ECTRIMS meeting, where neurologists with expertise in multiple sclerosis (MS) meet to review the new developments presented at the ECTRIMS. AIM: This article, published in two parts, summarises the presentations of the post-ECTRIMS meeting, held online on 16 and 17 October 2020. DEVELOPMENT: This second part highlights the importance of gender and age in understanding the pathology of the disease and optimising its management. The advances made in paediatric MS, from a neuropsychological and neuroimaging point of view, are presented. In turn, special attention is paid to the findings that contribute to a more personalised approach to therapy and to choosing the best treatment strategy (pharmacological and non-pharmacological) for each patient. Similarly, results related to possible strategies to promote remyelination are addressed. Although there are no major advances in the treatment of progressive forms, some quantitative methods for the classification of these patients are highlighted. In addition, the study also includes results on potential tools for assessment and treatment of cognitive deficits, and some relevant aspects observed in the spectrum of neuromyelitis optica disorders. Finally, the results of the papers considered as breaking news at the ECTRIMS-ACTRIMS are detailed. CONCLUSIONS: Most of the advances presented were related to the knowledge of paediatric MS, remyelination strategies and cognitive assessment in MS.

BACKGROUND: The recent development of highly effective treatments for multiple sclerosis (MS) and the potential risk of infectious complications require the development of prevention and risk minimisation strategies. Vaccination is an essential element of the management of these patients. This consensus statement includes a series of recommendations and practical scenarios for the vaccination of adult patients with MS who are eligible for highly effective immunosuppressive treatments. METHODOLOGY: A formal consensus procedure was followed. Having defined the scope of the statement, we conducted a literature search on recommendations for the vaccination of patients with MS and specific vaccination guidelines for immunosuppressed patients receiving biological therapy for other conditions. The modified nominal group technique methodology was used to formulate the recommendations. DEVELOPMENT: Vaccination in patients who are candidates for immunosuppressive therapy should be considered before starting immunosuppressive treatment providing the patient's clinical situation allows. Vaccines included in the routine adult vaccination schedule, as well as some specific ones, are recommended depending on the pre-existing immunity status. If immunosuppressive treatment is already established, live attenuated vaccines are contraindicated. For vaccines with a correlate of protection, it is recommended to monitor the serological response in an optimal interval of 1-2 months from the last dose.

INTRODUCTION: Multiple sclerosis is an inflammatory neurodegenerative disease of the central nervous system, which mainly affects young people of working and reproductive age, and represents the first cause of non-traumatic disability in this age group of the population. A north-south latitude gradient is recognised, with prevalence rates increasing as we move away from the equator. This gradient probably represents the genetic predisposition transmitted from the Scandinavian regions through the Viking invasions and could presuppose an influence of the vitamin D deficit related to a lower number of hours of sunshine per year. AIMS: To determine the prevalence and incidence of multiple sclerosis in the city of Ourense, Galicia. PATIENTS AND METHODS: The latitude coordinate of the city of Ourense is 42° 34' N. A retrospective epidemiological study covering the period from 2002 to 2016 was conducted. The prevalence date was 31 December 2016. According to the latest census, the population of the city of Ourense was 105,892 on 1 January 2016. RESULTS: Altogether, 195 cases were recorded, representing a prevalence of 184.1 cases/100,000 inhabitants. In the period 2002-2016, 127 cases of multiple sclerosis were diagnosed, representing an average incidence of 7.86 cases/100,000 inhabitants/year. CONCLUSION: The city of Ourense has the highest prevalence rate of multiple sclerosis of those studied to date in the Iberian Peninsula, with a figure that brings it closer to the data reported in more northern areas under Nordic and Anglo-American influence.
TITLE: Prevalencia de la esclerosis múltiple en la ciudad de Ourense, Galicia, noroeste de la Península Ibérica.Introducción. La esclerosis múltiple es una enfermedad inflamatoria y neurodegenerativa del sistema nervioso central, que afecta fundamentalmente a personas jóvenes en edad laboral y reproductiva, y que representa la primera causa de discapacidad no traumática en este rango etario de la población. Se reconoce un gradiente de latitud norte-sur, con un aumento de las tasas de prevalencia a medida que nos alejamos del ecuador. Este gradiente probablemente representa la predisposición genética transmitida desde las regiones escandinavas a través de las invasiones vikingas y podría presuponer una influencia del déficit de vitamina D en relación con un menor número de horas de sol anuales. Objetivo. Determinar la prevalencia e incidencia de la esclerosis múltiple en la ciudad de Ourense, Galicia. Pacientes y métodos. La ciudad de Ourense tiene una coordenada de latitud de 42° 34' N. Se ha realizado un estudio epidemiológico retrospectivo que abarca desde 2002 a 2016. La fecha de prevalencia fue el 31 de diciembre de 2016. El censo de la población de la ciudad de Ourense a 1 de enero de 2016 era de 105.892 habitantes. Resultados. Se registraron 195 casos, lo que representa una prevalencia de 184,1 casos/100.000 habitantes. En el período 2002-2016 se diagnosticaron 127 casos de esclerosis múltiple, lo que supone una incidencia media de 7,86 casos/ 100.000 habitantes/año. Conclusión. La ciudad de Ourense presenta la tasa de prevalencia de esclerosis múltiple más alta de las estudiadas hasta la actualidad en la Península Ibérica, con una cifra que la aproxima a los datos comunicados en áreas más septentrionales de influencia nórdica y anglosajona.

OBJECTIVE: The diagnosis of SARS-CoV-2 infection is crucial for medical and public health reasons, to allow the best treatment of cases and the best control of the pandemic. Serology testing allows for the detection of asymptomatic infections and 19-COVID cases once the virus has been cleared. We analyzed the usefulness of the SARS-CoV-2 rapid test of Autobio and tried to correlate its pattern with the severity of COVID19 infection. METHODS: We analyzed the accuracy and clinical usefulness of a point-of-care IgM and/or IgG test for SARS-CoV-2 in 35 COVID-19 patients [12 (34.3%) mild-moderate and 23 (65.7%) severe-critical] admitted to a field hospital in Madrid, as well as in 5 controls. RESULTS: The mean time from the first day of symptoms to the antibody test was 28 days (SD: 8.7), similar according to the severity of the disease. All patients with SARS-CoV-2 PCR+ showed the corresponding IgG positivity, while these results were negative in all control individuals. A total of 26 (74%) cases also presented with positive IgM, 19 (83%) were severe-critical cases and 7 (58%) were mild-moderate cases. The IgM response lasted longer in the severe critical cases (mean: 29.7 days; SD: 8.4) compared to the moderate cases (mean: 21.2 days; SD: 2.0).. CONCLUSIONS: Rapid serology tests are useful for the diagnosis of patients with COVID-19 (mainly IgG detection) and may also be correlated with the severity of the infection (based on IgM detection).

INTRODUCTION: Like every year, after the ECTRIMS Congress, renowned Spanish neurologists who are experts in multiple sclerosis presented the main novelties in research in this field at the Post-ECTRIMS Meeting. AIM: To summarise the content presented at the 12th edition of the Post-ECTRIMS Meeting, which took place in September 2019 in Sevilla and is presented in two parts. DEVELOPMENT: In this second part, the most recent evidence on the use of disease-modifying treatments during pregnancy is presented. Details are provided concerning the results of phase 3 clinical trials conducted to evaluate the efficacy and safety of two potential disease-modifying treatments for relapsing-remitting multiple sclerosis: ponesimod and ofatumumab. For the progressive forms, both available disease modifying treatments and others still in the research phase are reviewed. In the field of stem cell therapies, the article includes the results of the only clinical trial carried out to date comparing patients with relapsing-remitting multiple sclerosis treated with autologous haematopoietic stem cell transplantation and those treated with disease-modifying therapies. There are no important developments as regards symptomatic treatments, although the European Academy of Neurology has published a guide on palliative care. The various sources of information that collect pharmacovigilance data in the post-marketing setting are reviewed. CONCLUSIONS: Patients diagnosed in recent years tend to have less severe multiple sclerosis, probably due to the fact that it is diagnosed in its milder stages together with the steady increase in the number of treatments available.
TITLE: XII Reunión Post-ECTRIMS: revisión de las novedades presentadas en el Congreso ECTRIMS 2019 (II).Introducción. Como cada año, tras la celebración del Congreso del ECTRIMS, reconocidos neurólogos españoles expertos en esclerosis múltiple expusieron en la Reunión Post-ECTRIMS las principales novedades en investigación en este ámbito. Objetivo. Sintetizar el contenido presentado en la XII edición de la Reunión Post-ECTRIMS, que tuvo lugar en septiembre de 2019 en Sevilla y que se presenta en dos partes. Desarrollo. En esta segunda parte, se exponen las evidencias más recientes sobre el uso de tratamientos modificadores de la enfermedad durante el embarazo. Se detallan los resultados de ensayos clínicos en fase 3 en los que se ha evaluado la eficacia y la seguridad de dos potenciales tratamientos modificadores de la enfermedad para la esclerosis múltiple remitente recurrente: ponesimod y ofatumumab. Para las formas progresivas, se revisan los tratamientos modificadores de la enfermedad disponibles y en investigación. En el ámbito de las terapias con células madre, se incluyen los resultados del único ensayo clínico hasta la fecha que compara a pacientes con esclerosis múltiple remitente recurrente tratados con trasplante autólogo de células madre hematopoyéticas y a los tratados con tratamientos modificadores de la enfermedad. No hay grandes novedades sobre tratamientos sintomáticos, aunque la Academia Europea de Neurología ha publicado una guía sobre cuidados paliativos. Se revisan las distintas fuentes de información que recogen datos de farmacovigilancia en el entorno poscomercialización. Conclusiones. Los pacientes diagnosticados en los últimos años tienden a tener una menor gravedad de la esclerosis múltiple, probablemente debido al diagnóstico desde sus estadios más leves y al continuo aumento de tratamientos disponibles.

INTRODUCTION: Like every year, after the ECTRIMS Congress, renowned Spanish neurologists who are experts in multiple sclerosis presented the main novelties in research in this field at the Post-ECTRIMS Meeting. AIM: To summarise the content presented at the 12th edition of the Post-ECTRIMS Meeting, which took place in September 2019 in Sevilla and is presented in two parts. DEVELOPMENT: This first part addresses the latest studies on vitamin D deficiency and the discrepancies that currently exist regarding its treatment. The advances made in epigenetics allow us to present this approach as a possible biomarker of multiple sclerosis. An account is provided to explain the growing importance of imaging techniques to detect atrophy and other phenomena that occur during the disease, such as changes in iron concentration or remyelination processes, which allow us to further our understanding of the mechanisms of cortical pathology, and the dimensionality of neurodegeneration during its course. Findings related to immunological mechanisms and advances in potential antigen-specific therapies are discussed. The contribution presents the latest studies on the assessment of cognitive impairment and its rehabilitation, which are becoming increasingly important due to the high prevalence of these disorders and the absence of their systematic assessment in clinical practice. Finally, the unmet social and health needs of multiple sclerosis patients in our country are presented, with emphasis on the current deficits in the system of social protection.

Objetivo. Sintetizar el contenido presentado en la XII edición de la Reunión Post-ECTRIMS, que tuvo lugar en septiembre de 2019 en Sevilla y que se presenta en dos partes. Desarrollo. Esta primera parte aborda los últimos estudios sobre el déficit de vitamina D y las discrepancias existentes acerca de su tratamiento. Los avances en epigenética realizados permiten presentar esta aproximación como un posible biomarcador de la esclerosis múltiple. Se explica el creciente protagonismo de las técnicas de imagen para detectar la atrofia y otros fenómenos que acontecen durante la enfermedad, como los cambios en la concentración de hierro o los procesos de remielinización, que nos permiten ganar comprensión sobre los mecanismos de la patología cortical, y sobre la dimensionalidad de la neurodegeneración durante su evolución. Se discuten los hallazgos relacionados con los mecanismos inmunológicos y los avances realizados en las potenciales terapias específicas del antígeno. Se presentan los últimos estudios sobre la evaluación del deterioro cognitivo y su rehabilitación, que cobran cada vez más importancia por la alta prevalencia de estas alteraciones y por la ausencia de su evaluación sistemática en la práctica clínica. Por último, se exponen las necesidades sociosanitarias no cubiertas de los pacientes de esclerosis múltiple en nuestro país, poniendo el acento en los déficits actuales del sistema de protección social.

Thyroid disease is common in cats, but little is known about the biologic variability of serum thyroid hormone concentrations and its impact on diagnostic utility in either healthy cats or cats with thyroid disease. The purpose of this study was to determine the biological variation, index of individuality, and reference change values for thyroid hormones and thyroid-stimulating hormone (TSH) in clinically healthy cats. Serum samples for analysis of total thyroxine (T4), triiodothyronine (T3), free T4 by dialysis, and TSH were obtained weekly for 6 wk from 10 healthy cats, then frozen until single-batch analyzed. Data were evaluated for outliers, and we determined the CV within individual cats (CVI) and between individual cats (CVG) for each hormone and the variation between duplicates or analytical variation (CVA). The index of individuality and reference change values for each hormone were then calculated. Serum concentrations of total T4, free T4, T3, and TSH all showed greater variation between cats (CVG) than within cats (CVI). Total and free T4 had an intermediate index of individuality (1.1 and 1.2, respectively), suggesting that these hormones would be best evaluated by a combination of their population-based reference intervals and reference change values. Serum TSH concentrations had high index of individuality (1.8), suggesting this hormone would be best evaluated with reference change values rather than the population-based reference interval. Total T3 also had a high calculated index of individuality (1.8); however, T3 had high ratio of analytical variation (CVA) to within cat variation (CVI), so RCV could not be accurately calculated. This study demonstrates that clinically normal cats show considerable interindividual biological variation in serum thyroid hormone and TSH concentrations, whereas the intraindividual variability in hormone concentrations is much narrower. This suggests that for all serum thyroid hormones, but especially serum TSH and T3 concentrations, comparing individual cat's hormone results to a population-based reference interval may be misleading, especially in those with early or subclinical thyroid disease. Clinicians might improve the diagnosis of feline thyroid disease by establishing baseline concentrations of T4, free T4, T3, and TSH for individual cats (ideally when healthy) and applying reference change values to subsequent measurements.

The IX Course of Antimicrobials and Infectious Diseases update included a review of the main issues in clinical microbiology, epidemiology and clinical aspects for a current approach of infectious pathology. The present introduction summarizes about the most important meetings related to infectious diseases during 2018 (ECCMID, IAS, ASM and ID Week). In addition, the course provides a practical information to focus on nosocomial infection models, with immunosuppressed patients or complex multidrug-resistant pathogens. The closing lecture of this year reviewed the infection during donation process.

OBJECTIVE: The aim of the study was to carry out an epidemiological analysis of patients with carbapenemase-producing Enterobacteriaceae (CPE) isolations in our hospital as well as to perform a description of the genotypic temporal evolution of CPE isolated. METHODS: An observational prospective cohort study was performed involving all patients with CPE isolates from clinical samples during November 2014 to November 2016 in a Spanish teaching hospital. Patients were clinically evaluated and classified either as infected or colonized. Information on the consumption of carbapenems in the hospital during the study period was also analyzed. PCR was used for identification of the carbapenemase genes blaKPC, blaVIM, and blaOXA-48. RESULTS: A total of 301 CPE isolates were obtained (107 in 2014, 89 in 2015 and 105 in 2016). Klebsiella pneumoniae (73.4%) was the most prevalent microorganism. Hundred and seventy (56.7%) of carbapenemases detected were blaOXA-48, 73 (24.3%) were blaKPC and 57 (19%) were blaVIM. In year 2014 KPC was predominant while in 2016 OXA-48 predominated. In 2014 we observed a significant association between the medical wards and the ICU with a higher prevalence of OXA-48 (OR 4.15; P<0.001) and VIM (OR 7.40; P<0.001) in the univariate analysis, in the following years there was no association. Regarding the clinical significance of microbiological results after assessing our patients, 60% of isolates represented infection and 40% behaved as colonizers. One third of hospitalized patients with CPE isolation died within 30 days, regardless of whether they were colonized or infected. CONCLUSIONS: We have observed an epidemiological change in the genotypes of our isolates along the study period. A thorough knowledge of the CPE's epidemiological distribution in each hospital is fundamental for optimizing antimicrobial chemotherapy.

BACKGROUND: Allograft contamination during extraction represents a major limiting factor for tissue bank availability. Contamination rates remain persistently high independent of the hospital, country or year considered. AIM: To analyse the factors associated with contamination of bone and tendon samples extracted from Spanish donors. METHODS: Data for 1162 bone and tendon samples extracted from 102 donors between 2014 and 2017 were collected retrospectively from the hospital database. Descriptive statistics, potentially associated factors and correlation of contamination between samples extracted from different anatomical locations of the same donor were analysed. FINDINGS: In total, 227 (19.54%) of the extracted samples [131 (18.49%) bone samples and 96 (20.92%) tendon samples] rendered positive cultures and were discarded. Male sex [odds ratio (OR) 2.023; P=0.019], extraction of >10 samples per donor (OR 1.997; P<0.001) and extraction time >240 min (OR 1.755; P=0.001) were factors independently associated with a higher contamination rate. Meanwhile, the tissue sample type 'bone-patellar tendon-bone' was associated with a significantly lower contamination rate (OR 0.446; P=0.001). Significant correlation between certain localization of contaminated samples and the concordance of bacterial species was also observed. CONCLUSION: Factors related to the extraction procedure, such as total extraction time, extraction sequence, number of samples extracted and anatomical location of extracted samples, play a major role in allograft contamination. Further optimization of procedures, guided by the contamination patterns analysed in this study, should help to increase tissue bank availability.

RHDVb has become the dominant RHDV on the Iberian Peninsula. A better understanding of its pathogenicity is required to aid control measures. Thus, the clinical course, humoral immune response, viraemia and kinetics of RHDV-N11 (a Spanish RHDVb isolate) infection in different tissues at both viral RNA and protein levels were studied in experimentally infected young and adult rabbits. The case fatality rate differed between the two age groups, with 21% of kits succumbing while no deaths were observed in adults. Fever and viremia were strongly associated with death, which occurred 48â¯h post infection (PI) too fast for an effective humoral immune response to be mounted. A significant effect on the number of viral RNA copies with regard to the variables age, tissue and time PI (pâ¯<â¯0.0001 in all cases) was detected. Histological lesions in infected rabbits were consistently more frequent and severe in liver and spleen and additionally intestine in kits, these tissues containing the highest levels of viral RNA and protein. Although no adults showed lesions or virus antigen in intestine, both kits and adults maintained steady viral RNA levels from days 1 to 7 PI in this organ. Analysis revealed the fecal route as the main dissemination route of RHDV-N11. Subclinically infected rabbits had detectable viral RNA in their faeces for up to seven days and thus may play an important role spreading the virus. This study allows a better understanding of the transmission of this virus and improvement of the control strategies for this disease.
