Core data set para la generación de datos de la vida real en esclerosis múltiple: adaptación de una iniciativa global para América Latina / Core data set for real world data in multiple sclerosis: customization for latin america from a global task force recommendation

Introducción: Los objetivos primarios del core data set son reducir la heterogeneidad y promover la armonización entre las fuentes de datos en la esclerosis múltiple (EM), reduciendo así el tiempo necesario para ejecutar esfuerzos en la recolección de datos de vida real. Recientemente, un grupo liderado por la Multiple Sclerosis Data Alliance ha desarrollado un core data set para la recolección de datos del mundo real en EM a nivel global. Nuestro objetivo ha sido adaptar y consensuar este conjunto de datos globales a las necesidades de América Latina para que pueda ser implementado por los registros ya desarrollados y en proceso de desarrollo en la región. Material y métodos. Se conformó un grupo de trabajo regionalmente y se adaptó el core data set creado globalmente (proceso de traducción al español, incorporación de variables regionales y consenso sobre variables que se iban a utilizar). El consenso se obtuvo a través de la metodología Delphi remoto de ronda de cuestionarios y discusión a distancia de las variables del core data set. Resultados: Veinticinco profesionales de América Latina llevaron adelante el proceso de adaptación entre noviembre de 2022 y julio de 2023. Se estableció un acuerdo sobre un core data set de nueve categorías y 45 variables, versión 2023, con la sugerencia de implementarlo en registros desarrollados o en vías de desarrollo y cohortes de EM en la región. Conclusión: El core data set busca armonizar las variables recolectadas por los registros y las cohortes de EM en América Latina con el fin de facilitar dicha recolección y permitir una colaboración entre fuentes. Su implementación facilitará la recolección de datos de vida real y la colaboración en la región.(AU)

Introduction: The primary objective of the core data set is to reduce heterogeneity and promote harmonization among data sources in EM, thereby reducing the time needed to execute real life data collection efforts. Recently, a group led by the Multiple Sclerosis Data Alliance has developed a core data set for collecting real-world data on multiple sclerosis (MS) globally. Our objective was to adapt this global data set to the needs of Latin America, so that it can be implemented by the registries already developed and in the process of development in the region. Material and methods: A working group was formed regionally, the core data set created globally was adapted (translation process into Spanish, incorporation of regional variables and consensus on variables to be used). Consensus was obtained through the remote Delphi methodology of a round of questionnaires and remote discussion of the core data set variables. Results: A total of 25 professionals from Latin America carried out the adaptation process between November 2022 and July 2023. Agreement was established on a core data set of nine categories and 45 variables, version 2023 to suggest its implementation in developed or developing registries, and MS cohorts in the region. Conclusion: The core data set seeks to harmonize the variables collected by registries and cohorts in MS in Latin America in order to facilitate said collection and allow collaboration between sources. Its implementation will facilitate real life data collection and collaboration in the region.(AU)

Estudio de prevalencia, conocimiento y control de la hipertensión arterial en barrios vulnerables de Argentina / Prevalence, knowledge and control of arterial hypertension in vulnerable neighborhoods of Argentina: A Cross-sectional Study

Introducción: La hipertensión arterial (HTA) representa el principal factor de riesgo individual, con mayor carga a nivel mundial de enfermedades cardiovasculares (ECV). En nuestro país, algunos trabajos epidemiológicos han mostrado marcadas diferencias en las prevalencias de estos factores de riesgo de acuerdo con la población evaluada. Sin embargo, no hay estudios epidemiológicos de evaluación de factores de riesgo cardiovascular exclusivos referentes a barrios vulnerables con muy bajos recursos económicos, socioculturales y poca accesibilidad a los sistemas de salud. Materiales y métodos: Estudio observacional de corte transversal multicéntrico en habitantes de comunas vulnerables de muy bajos recursos, como asentamientos populares y barrios carenciados con muestreo aleatorizado simple de casas. Se realizaron tomas de presión arterial (PA), medidas antropométricas, así como cuestionarios epidemiológicos, económicos y socioculturales. Se describen los hallazgos: prevalencia, conocimiento y control de la PA en las distintas regiones. Se efectuó una regresión logística para determinar las variables independientes a los resultados principales. Resultados: Se analizaron 989 participantes. La prevalencia de HTA global fue de 48,2%. Un total de 82% tenía un índice de masa corporal (IMC) >25 kg/m2. De estos pacientes, 45,3% tenían menos de seis años de educación. Este último aspecto se asoció a mayor prevalencia de HTA de forma independiente. De los hipertensos, 44% desconocían su padecimiento y solo en 17,2% estaba controlado, asociándose esto a tener obra social (OS) y mayor nivel educativo. Únicamente 24% estaban bajo tratamiento combinado. Conclusión: La prevalencia de HTA en barrios vulnerables es elevada, superando a la de otros estratos sociales con niveles de conocimiento, tratamiento y control de la HTA bajos, similar a otras poblaciones. Se detectó un uso insuficiente de la terapia combinada.

Introduction: Hypertension (HTN) represents the primary individual risk factor, contributing significantly to the global burden of cardiovascular diseases (CVD). In our country, epidemiological research has highlighted substantial variations in the prevalence of these risk factors across different populations. However, there is a lack of epidemiological studies assessing exclusive cardiovascular risk factors within vulnerable neighborhoods characterized by extremely limited economic resources, sociocultural challenges, and inadequate healthcare access. Methods: A multicenter cross-sectional observational study was conducted among individuals residing in economically deprived and marginalized communities, including informal settlements and underprivileged neighborhoods. Simple random sampling of households was employed. Blood pressure measurements, anthropometric assessments, and epidemiological, economic, and sociocultural questionnaires were administered. Results encompass prevalence rates, awareness levels, and blood pressure control across diverse regions. Logistic regression was utilized to identify independent variables influencing primary outcomes. Results: A total of 989 participants were analyzed. The overall prevalence of hypertension was 48.2%. About 82% had a body mass index (BMI) >25. Approximately 45.3% had less than 6 years of formal education. Independent association was established between education levels below 6 years and higher hypertension prevalence Among hypertensive individuals, 44% were unaware of their condition, with only 17.2% achieving control, correlated with having health insurance and a higher educational background. Merely 24% were receiving combined therapy. Conclusion: The prevalence of hypertension within vulnerable neighborhoods is alarmingly high, surpassing rates in other social strata. Knowledge, treatment, and control levels of hypertension are suboptimal, comparable to other populations... (AU)

Brazilian Dialysis Survey 2022 / Censo Brasileiro de Diálise 2022

Abstract Introduction: The Brazilian Dialysis Survey (BDS) is an annual national survey about patients on chronic dialysis that contributes to health policies. Objective: To report the 2022 epidemiological data from the BDS of the Brazilian Society of Nephrology (BSN). Methods: A survey was carried out in Brazilian chronic dialysis centers using an online questionnaire that included clinical and epidemiological aspects of patients on chronic dialysis, dialysis therapy data, and dialysis center characteristics. Results: Overall, 28% (n = 243) of the centers answered the questionnaire. In July 2022, the estimated total number of patients on dialysis was 153,831. The estimated prevalence and incidence rates of patients per million population (pmp) were 758 and 214, respectively. Of the prevalent patients, 95.3% were on hemodialysis (HD, 4.6% of these on hemodiafiltration) and 4.7% on peritoneal dialysis (PD). Only 1.3% of patients were not vaccinated against COVID-19. The prevalence of anemia (Hb < 10g/dL) was 27% and hyperphosphatemia (P > 5.5mg/dL) reached 30%. The estimated overall crude annual mortality rate was 17.1%. Conclusions: The absolute number and prevalence rate of patients on chronic dialysis continue to increase. A growing number of patients were receiving hemodiafiltration. The mortality rate decreased, probably due to the end of COVID-19 pandemic. The conclusions were drawn in the context of relatively low voluntary participation, which imposed methodological limitations on our estimates.

Resumo Introdução: O Censo Brasileiro de Diálise (CBD) é uma pesquisa nacional anual sobre pacientes em diálise crônica que contribui para as políticas de saúde. Objetivo: Informar os dados epidemiológicos de 2022 do CBD da Sociedade Brasileira de Nefrologia (SBN). Métodos: Foi realizada uma pesquisa em centros brasileiros de diálise por meio de um questionário online que incluiu aspectos clínicos e epidemiológicos de pacientes em diálise crônica, dados da terapia dialítica e características do centro de diálise. Resultados: No total, 28% (n = 243) dos centros de diálise ativos cadastrados na SBN responderam ao questionário. Em julho de 2022, o número total estimado de pacientes em diálise era de 153.831. As taxas estimadas de prevalência e incidência de pacientes por milhão (ppm) de habitantes foram 758 e 214, respectivamente. Dos pacientes prevalentes, 95,3% estavam em hemodiálise (HD; 4,6% desses em hemodiafiltração) e 4,7% em diálise peritoneal (DP). Apenas 1,3% dos pacientes não foram vacinados contra a COVID-19. A prevalência de anemia (Hb < 10g/dL) foi de 27% e de hiperfosfatemia (P > 5,5mg/dL) alcançou 30%. A taxa bruta total anual de mortalidade estimada foi de 17,1%. Conclusões: O número absoluto e a taxa de prevalência de pacientes em diálise crônica continuam a aumentar. Um número crescente de pacientes estava em hemodiafiltração. A taxa de mortalidade diminuiu, provavelmente devido ao fim da pandemia da COVID-19. As conclusões foram de um contexto de participação voluntária relativamente baixa, o que impõe limitações metodológicas às nossas estimativas.

A relação entre cafeína e zumbido: sinopse baseada em evidências

Contexto: A associação entre a cafeína e o zumbido é bastante descrita na literatura, mas o papel da cafeína no zumbido não é claramente explicado. A redução no consumo de cafeína ou mesmo sua abolição é recomendada como meio de melhorar o zumbido. Entretanto, há fundamentação nessa orientação? Há evidências científicas que respaldam essa ação? Objetivo: Avaliar as evidências relativas à possível associação entre a ingestão de cafeína e o zumbido. Métodos: Trata-se de sinopse baseada em evidências. Procedeu-se à busca por estudos que associavam cafeína e zumbido em quatro bases de dados: Cochrane - Central de Registros de Ensaios Clínicos - CENTRAL (2023), PubMed (1966-2023), Portal Regional Biblioteca Virtual em Saúde (1982-2023) e Embase (1974-2023). Foram utilizados os descritores "caffeine" e "tinnitus". Dois pesquisadores, independentemente, extraíram os dados e avaliaram a qualidade dos estudos para a síntese. O desfecho primário de análise envolveu a relação entre o consumo de cafeína e o zumbido. Resultados: Foram encontradas 79 referências. Cinco estudos (1 ensaio clínico, 2 coortes e 2 estudos caso-controle) foram incluídos (n = 65.856 participantes). Discussão: A literatura apresenta poucos estudos que buscam a relação entre o consumo de cafeína e o zumbido. Trata-se de estudos com amostragem reduzida e limitações metodológicas. A evidência é baixa e são necessários novos estudos. Conclusões: Não é possível concluir sobre uma possível relação entre a cafeína e o zumbido. Há poucos estudos prospectivos realizados e a evidência é baixa, sendo necessária a realização de novos estudos prospectivos de qualidade para elucidação dessa questão.

CORRELATION OF NEUTROPHIL-LYMPHOCYTE RATIO (NLR) AND PLATELET-LYMPHOCYTE RATIO (PLR) WITH COMPLICATIONS AND POSTOPERATIVE SURVIVAL IN SURGERY FOR BONE METASTASIS OF THE APPENDICULAR SKELETON / CORRELAÇÃO DO NEUTROPHIL-LYMPHOCYTE RATIO (NLR) E PLATELET-LYMPHOCYTE RATIO (PLR) COM COMPLICAÇÕES E SOBREVIDA PÓS-OPERATÓRIAS NA CIRURGIA PARA METÁSTASE ÓSSEA DO ESQUELETO APENDICULAR

Introduction: Bone metastasis is the most common malignant neoplasm of the skeleton, and surgical decision-making depends on multiple factors, including postoperative complications and life expectancy. The identification of new prognostic factors can assist in decision making. Objective: In long bones metastases, to analyze the incidence of complications and postoperative survival up to 1 year, correlating them with NLR and PLR. Method: Review of 160 medical records of patients who underwent surgery for bone metastasis in the appendicular skeleton. In addition to epidemiological characteristics, NLR and PLR values were determined, correlating them with survival and complications. Result: Women represented 64.5% with a primary breast tumor in 62.6%; the proximal femur was the most affected; median survival was 13.2 months and in 1 year 34.7%. Tumor resection with endoprosthesis was more common. The post-surgical complication rate was 10% and the average time for post-operative complications to occur was 27.9 days (0-140). An association between the neutrophil variable and postoperative complications was found (p=0.04). For every 100 more units of neutrophils there was a 1% increase in the chances of post-surgical complications. Mean NLR and PLR values were, respectively, 5.3 (0.2-30.7) and 199.7 (32.1-676.7). Patients with NLR NLR ≥ 2 (p<0,001) showed a decrease in survival from 92,3% to 62,5% at the 3rd month, and from 61,5% to 31,3% at 1 year. Those with PLR ≥209 (p<0.001) showed a decrease in survival from 69% to 59.3% at the 3rd month, and from 40.2% to 25.9% at 1 year. Conclusion: There was no positive association between NLR and PLR with postoperative complications, but strongly yes with survival from the 3rd month after surgery.

Introdução: Metástase óssea é a neoplasia maligna mais comum do esqueleto, e a tomada de decisão cirúrgica depende de múltiplos fatores, incluindo as complicações pós-operatórias e a expectativa de vida. A identificação de novos fatores prognósticos pode auxiliar na tomada de decisão. Objetivo: Analisar em metástases de ossos longos, a incidência de complicações e sobrevida pós-operatórias até 1 ano correlacionando-as com NLR e PLR. Método: Revisão de 160 prontuários de operados por metástase óssea no esqueleto apendicular. Além de características epidemiológicas, foram determinados os valores de NLR e PLR correlacionando-os com sobrevida e complicações. Resultado: Mulheres representaram 64,5% com tumor primário na mama em 62,6%; o fêmur proximal foi o mais acometido; sobrevida média foi 13,2 meses e a de 1 ano 34,7%; ressecção tumoral com endoprótese foi mais comum. A taxa de complicação pós-cirúrgicas foi de 10% e o tempo médio para a ocorrência de complicações pós-operatórias foi de 27,9 dias (0-140). Foi encontrada associação da variável neutrófilos com a complicação pós-operatória (p=0,04). A cada 100 unidades a mais de neutrófilos houve aumento de 1% nas chances de complicações pós-cirúrgicas. Valores médios do NLR e PLR foram, respectivamente, 5,3 (0,2-30,7) e 199,7 (32,1-676,7).  Os pacientes com NLR ≥ 2 (p<0,001) apresentaram diminuição na sobrevida de 92,3% para 62,5% no 3° mês e de 61,5% para 31,3% em 1 ano. Aqueles com PLR ≥209 (p<0,001) apresentaram diminuição na sobrevida de 69% para 59,3% no 3° mês, e de 40,2% para 25,9% em 1 ano. Conclusão: Não foi verificada associação positiva entre o NLR e o PLR com complicações pós-operatórias, mas com sobrevida fortemente sim, a partir do 3° mês de pós-operatório.

CAN NEUTROPHIL-LYMPHOCYTE RATIO (NLR) AND PLATELET-LYMPHOCYTE RATIO (PLR) BE PROGNOSTIC INDICATORS FOR OPERATIVE COMPLICATIONS AND SURVIVAL IN BONE METASTASES? / NEUTROPHIL-LYMPHOCYTE RATIO (NLR) E PLATELET-LYMPHOCYTE RATIO (PLR) PODEM SER INDICADORES DE PROGNÓSTICO PARA COMPLICAÇÕES OPERATÓRIAS E SOBREVIDA EM METÁSTASES ÓSSEAS?

Introduction: In general, inflammation stimulates the production and release of neutrophils and, at the same time, decreases the production of lymphocytes. Lymphopenia reflects that cell-mediated immunity is impaired, while neutrophilia represents a response to systemic inflammation in these cancers. Objective: To review the incidence of complications and postoperative survival rates in patients with bone metastases in long bones, correlating them with markers NLR and PLR. Method: Narrative review carried out collecting information published on virtual platforms in Portuguese and English, initially carried out by searching for descriptors related to the topic, which were: "lower extremity, surgery, metastasis, epidemiology, postoperative complications, neutrophils, lymphocytes, platelets". The extension incorporated AND or OR, by title and/or summary, and full reading of the texts most related to the topic. Result: 21 articles were included. Conclusion: The higher both the NLR and PLR are associated with lower survival in patients with bone metastases when undergoing surgical treatment, especially after 3 months postoperatively. However, there is still no confirmation that they signal any outcome, favorable or not, in relation to postoperative complications.

Introdução : De um modo geral, a inflamação estimula a produção e liberação de neutrófilos e, ao mesmo tempo, diminui a produção de linfócitos. A linfopenia reflete que a imunidade mediada pelas células é prejudicada, enquanto a neutrofilia representa resposta à inflamação sistêmica nesses cânceres. Objetivo : Revisar nos pacientes com metástase óssea em ossos ao longo da incidência de complicações e taxas de sobrevida pós-operatória correlacionando-as com os marcadores NLR e PLR. Método : Revisão narrativa feita colhendo informações publicadas em plataformas virtuais em português e inglês inicialmente realizada por busca dos descritores relacionados ao tema que foram: "extremidade inferior, cirurgia, metástase, epidemiologia, complicações pós-operatórias, neutrófilos, linfócitos, plaquetas" e seus equivalentes em inglês " extremidade inferior, cirurgia, metástase, epidemiologia, sobrevivência, complicações, neutrófilos, linfócitos, plaquetas sanguíneas ". A extensão incorporou AND ou OR, pelo título e/ou resumo, e leitura na íntegra dos textos mais relacionados ao tema.  Resultado : Foram incluídos 21 artigos. Conclusão : Quanto maiores, tanto o NLR quanto o PLR estão associados à menor sobrevida em pacientes com MO quando submetidos ao tratamento cirúrgico, especialmente após 3 meses de pós-operatório. Contudo, ainda não há confirmação de que eles sinalizam algum estágio, positivo ou não, em relação às complicações pós-operatórias.

Epidemiología y caracterización molecular de las miopatías genéticas en adultos en una región del sureste de España / Epidemiology and molecular characterization of adult genetic myopathies in a southeastern region of Spain

Introducción Las miopatías genéticas constituyen un conjunto de enfermedades raras que impactan significativamente en la funcionalidad y la calidad de vida del paciente. Un diagnóstico temprano de las miopatías genéticas puede prevenir complicaciones futuras y proporcionar a las familias asesoramiento genético. A pesar del impacto sustancial de las miopatías genéticas en población adulta, la epidemiología global de estos trastornos está inadecuadamente abordada en la bibliografía.ObjetivosMejorar el entendimiento tanto de la epidemiología como de la genética de estos trastornos en la provincia de Alicante, situada en el sureste de España. Material y métodos. Entre 2020 y 2022, se llevó a cabo un estudio observacional prospectivo en el área de salud Alicante-Hospital General, que incluyó a pacientes de 16 años o más con sospecha de miopatías genéticas. Se recopilaron datos sociodemográficos, clínicos y genéticos. La fecha de referencia para el cálculo de la prevalencia se estableció el 31 de diciembre de 2022. Se utilizaron datos demográficos oficiales del área de salud para establecer la población en riesgo.ResultadosEn total, se identificó a 83 pacientes con miopatía genéticamente confirmada, lo que dio lugar a una prevalencia total de 29,59 casos por cada 100.000 habitantes. El rendimiento diagnóstico de las pruebas genéticas moleculares fue del 69,16%. Las miopatías genéticas más frecuentes incluyeron la distrofia miotónica (27,5%), las distrofinopatías (15,7%) y la distrofia facioescapulohumeral (15,7%).ConclusiónLa prevalencia de las miopatías genéticas puede variar considerablemente dependiendo de la región geográfica y la población estudiada. El análisis del rendimiento diagnóstico sugiere que los estudios genéticos deberían considerarse útiles en el diagnóstico de las miopatías genéticas. (AU)

Introduction. Genetic myopathies constitute a collection of rare diseases that significantly impact patient functionality and quality of life. Early diagnosis of genetic myopathies can prevent future complications and provide families with genetic counselling. Despite the substantial impact of genetic myopathies on the adult population, the global epidemiology of these disorders is inadequately addressed in the literature.Aims. To enhance understanding of both the epidemiology and genetics of these disorders within the province of Alicante, situated in southeastern Spain.Material and methods. Between 2020 and 2022, a prospective observational study was conducted at the Alicante Health Area-General Hospital, enrolling patients aged 16 years or older with suspected genetic myopathies. Sociodemographic, clinical, and genetic data were collected. The reference date for prevalence calculation was established as December 31, 2022. Official demographic data of the health area were used to set the population at risk.Results. In total, 83 patients were identified with confirmed genetically related myopathy, resulting in an overall prevalence of 29.59 cases per 100,000 inhabitants. The diagnostic yield for molecular genetic testing was found to be 69.16%. The most prevalent genetic myopathies identified included myotonic dystrophy (27.5%), dystrophinopathies (15.7%), and facioscapulohumeral dystrophy (15.7%).Conclusion. The prevalence of GMs can vary considerably depending on the geographical region and the studied population. The analysis of diagnostic yield suggests that genetic studies should be considered useful in the diagnosis of genetic myopathies. (AU)

Numerical values and impact of hypertension in Spain.

In Spain, 33% of adults aged 30 to 79 years (10 million) were hypertensive in 2019. Among them, 68% were diagnosed, 57% received drug therapy, and effective therapeutic coverage (control) reached 33%. Both diagnosis and control show geographical and social disparities. Approximately 46 000 cardiovascular deaths per year are attributable to hypertension. In recent decades, the control of hypertension has increased, due to improvements in lifestyle measures and increased use of polytherapy, coinciding with a reduction in stroke mortality. There are several modifiable determinants of the lack of hypertension control: a) white-coat phenomenon affects 22% to 33% of treated individuals, partly due to the limited availability of ambulatory blood pressure monitoring (ABPM) (49%) and self-measured BP (SMBP) (78%); b) inadequate patient adherence to medication and healthy lifestyles (weight loss, the most effective measure, is the least used, ≈40%); and c) insufficient use of polytherapy (≈55%). The remaining challenges include: a) technological aspects, such as measuring BP with more accurate techniques (ABPM, SMBP) and using cardiovascular-risk estimation tools (eg, SCORE); b) clinical challenges, such as reducing therapeutic inertia (≈59%), involving patients in their own management (medication adherence, ≈62%) and effectively implementing clinical guidelines); and c) public health challenges, such as reducing the burden of obesity (≈24%), monitoring progress with updated surveys, and setting national BP control targets.

[Prevalence of burnout syndrome in physicians working in Spain: systematic review and meta-analysis]. / Prevalencia del síndrome de burnout en médicos que trabajan en España: revisión sistemática y metaanálisis.

OBJECTIVE: To analyze the prevalence of burnout syndrome in physicians working in Spain through a systematic review with meta-analysis METHOD: We searched PubMed/MEDLINE, Embase, and PsycINFO (up to June 2023). Observational studies conducted in Spain reporting the prevalence of burnout in physicians were included. From each study, methodological characteristics and results were extracted, and their quality was evaluated. We performed a narrative synthesis with random effects meta-analysis to calculate proportions. RESULTS: Sixty-seven studies with 16,076 participants were included. For the primary outcome, the meta-analysis revealed a global prevalence of burnout in physicians of 24% (95%CI: 19%-29%; 46 studies; 8821 participants; I2=97%). From subgroup analysis, differences were observed depending on the diagnostic criteria used: 18% (95%CI: 13%-23%) for three dimensions of burnout, 29% (95%CI: 24%-34%) for two dimensions and 51% (95%CI: 42%-60%) for one dimension. The heterogeneity between studies could not be fully explained through additional analyses where non-statistically significant differences were found with other variables (e.g., study quality, setting, professional category or medical specialty). CONCLUSIONS: A high prevalence of burnout syndrome was found in physicians working in Spain. These results can contribute to estimating the burden associated with burnout in physicians at a national level and to the design of future studies. Strategies appear to be necessary to prevent and mitigate this situation. PROTOCOL REGISTRATION: Open Science Framework: https://osf.io/b2h4m/.

Fibrosis avanzada asociada a esteatohepatitis no alcohólica (NASH) en España: resultados de un estudio Delphi / Advanced fibrosis associated with non-alcoholic steatohepatitis (NASH) in Spain: results of a Delphi study

Objetivo: Describir de manera detallada la epidemiología, diagnóstico, manejo clínico, opciones de tratamiento, impacto en la calidad de vida y necesidades no cubiertas de los pacientes con fibrosis hepática avanzada (F3-F4) asociada a esteatohepatitis no alcohólica (NASH) en España. Metodología: Estudio Delphi de dos rondas de consulta con 41 hepatólogos expertos de 16 comunidades autónomas para recoger su experiencia en práctica clínica. Resultados: La prevalencia estimada de pacientes adultos diagnosticados de fibrosis F3-F4 asociada a NASH en España es de 0,019% (intervalo de confianza [IC] 95%: 0,019-0,020%). Aproximadamente 7.588 adultos con este padecimiento están actualmente diagnosticados y son manejados en los Servicios de Aparato Digestivo de los hospitales españoles, y alrededor de 1.881 nuevos pacientes son diagnosticados cada año. El manejo es multidisciplinar e incluye las especialidades de Aparato Digestivo, Endocrinología y Medicina interna, considerando las frecuentes comorbilidades metabólicas asociadas (obesidad, diabetes mellitus tipo 2 o sobrecarga férrica dismetabólica). A pesar del claro impacto en la calidad de vida, este no se evalúa rutinariamente en la práctica clínica. Las técnicas diagnósticas no invasivas más utilizadas son la elastografía de transición y el índice de fibrosis hepática 4 (FIB-4). La ausencia de tratamientos eficaces y seguros se presenta como la principal necesidad no cubierta para el manejo de estos pacientes. Conclusiones: Este estudio proporciona una representación de la situación actual de los pacientes diagnosticados con fibrosis F3-F4 asociada a NASH en España, incrementando la evidencia disponible y contribuyendo a la toma de decisiones informadas por parte de los profesionales y el sistema sanitario. (AU)

Objective: To describe in detail the epidemiology, diagnosis, clinical management, treatment options, impact on quality of life and unmet needs of patients with advanced liver fibrosis (F3-F4) associated with non-alcoholic steatohepatitis (NASH) in Spain. Methodology: Delphi study of two rounds of consultation rounds with 41 expert hepatologists from 16 autonomous communities to collect their experience in clinical practice. Results: The estimated prevalence of adult patients diagnosed with F3-F4 fibrosis associated with NASH in Spain is 0.019% (95% confidence interval [CI]: 0.019-0.020%). Approximately 7,588 adults with this condition are currently diagnosed and managed in the Digestive System Services of Spanish hospitals, and around 1,881 new patients are diagnosed each year. Management is multidisciplinary and includes the specialties of Digestive System, Endocrinology and Internal Medicine, considering the frequently associated metabolic comorbidities (obesity, type 2 diabetes mellitus or dysmetabolic iron overload). Despite a clear impact on quality of life, this it is not routinely evaluated in clinical practice. The most widely used non-invasive diagnostic techniques are transitional elastography and liver fibrosis index 4 (FIB-4). The absence of effective and safe treatments appears as the main unmet need for the management of these patients. Conclusions: This study provides a representation of the current situation of patients diagnosed with F3-F4 fibrosis associated with NASH in Spain, increasing the evidence available and contributing to informed decision-making by professionals and the health system.

Epidemiología molecular de la colonización nasofaríngea neumocócica en niños de Sevilla, tras la implementación del programa de vacunación con VNC13 en Andalucía (España) / Molecular epidemiology of pneumococcal carriage in children from Seville, following implementation of the PCV13 immunization program in Andalusia, Spain

Introducción: El programa de vacunación universal con la vacuna antineumocócica conjugada 13-valente (VNC13) se implantó en Andalucía en diciembre de 2016. Métodos: Estudio transversal de colonización nasofaríngea por Streptococcus pneumoniae. Se seleccionó a 397 niños sanos en centros de atención primaria de Sevilla durante los periodos 1/4/2018-28/2/2020 y 1/11/2021-28/2/2022 (periodo VNC13). Se utilizó una colección histórica de un estudio de colonización desarrollado en niños sanos y con infección respiratoria superior entre el 1/01/2006 y el 30/06/2008 (periodo VNC7) para comparar las distribuciones de serotipos/genotipos y las tasas de resistencias antibióticas. Resultados: Un total de 76 (19%) niños estaban colonizados con S. pneumoniae en el periodo VNC13 y se dispuso de 154 aislamientos del periodo VNC7. La colonización por serotipos incluidos en VNC13 disminuyó significativamente entre los periodos VNC13 y VNC7 (11 vs. 38%; p=0,0001); los serotipos 19F (8%), 3 (1%) y 6B (1%) fueron los únicos serotipos vacunales circulantes. Los serotipos 15B/C y 11A fueron los serotipos no VNC13 más prevalentes durante el periodo VNC13 (14% y 11%, respectivamente); este último se incrementó de forma significativa entre periodos de tiempo (p=0,04). El serotipo 11A solo se asoció en el periodo VNC13 con variantes resistentes a la ampicilina del clon Spain9V-ST156 (ST6521 y genéticamente relacionado ST14698), no detectados en el periodo anterior. Conclusiones: Hubo una circulación muy residual de los serotipos vacunales durante el periodo VNC13, con excepción del serotipo19F. El serotipo 11A se incrementó de forma significativa entre los periodos VNC13 y VNC7 por expansión clonal del genotipo resistente a la ampicilina ST6521.(AU)

Background: The 13-valent pneumococcal conjugate vaccine (PCV13) universal vaccination program was introduced in December 2016 in Andalusia. Methods: A cross-sectional study was conducted on the molecular epidemiology of pneumococcal nasopharyngeal colonization. A total of 397 healthy children were recruited from primary healthcare centres in Seville for the periods 1/4/2018 to 28/2/2020 and 1/11/2021 to 28/2/2022 (PCV13 period). Data from a previous carriage study conducted among healthy and sick children from 1/01/2006 to 30/06/2008 (PCV7 period) were used for comparison of serotype/genotype distributions and antibiotic resistance rates. Results: Overall, 76 (19%) children were colonized with S. pneumoniae during the PCV13 period and there were information available from 154 isolates collected during the PCV7 period. Colonization with PCV13 serotypes declined significantly in the PCV13 period compared with historical controls (11 vs. 38%, P=0.0001), being serotypes 19F (8%), 3 (1%) and 6B (1%) the only circulating vaccine types. Serotypes 15B/C and 11A were the most frequently identified non-PCV13 serotypes during the PCV13 period (14% and 11%, respectively); the later one increased significantly between time periods (P=0.04). Serotype 11A was exclusively associated in the PCV13 period with ampicillin-resistant variants of the Spain9V-ST156 clone (ST6521 and genetically related ST14698), not detected in the preceding period. Conclusions: There was a residual circulation of vaccine types following PCV13 introduction, apart from serotype 19F. Serotype 11A increased between PCV13 and PCV7 periods due to emergence and clonal expansion of ampicillin-resistant genotype ST6521.(AU)

Cribado poblacional de aneurismas de la aorta abdominal. Estudio piloto en Salamanca / Population screening for abdominal aortic aneurysms. Pilot study in Salamanca

Introducción: una estrategia para reducir la mortalidad de los aneurismas de la aorta abdominal es conocer su existencia en fase asintomática. Así podremos clasificar los pacientes, en función del tamaño del aneurisma, en candidatos a cirugía programada o a seguimiento periódico. Objetivos: conocer la eficacia, la seguridad y la aceptabilidad de un programa piloto de cribado de aneurismas de la aorta abdominal mediante ecografía abdominal realizada en una población de riesgo. Material y métodos: programa organizado por la Real Academia de Medicina y el Instituto de Investigación Biomédica y ejecutado por el Servicio de Angiología, Cirugía Vascular y Endovascular del Hospital Universitario de Salamanca. El cribado se realizó hace un año, en dos carpas situadas en una céntrica plaza de Salamanca. El análisis incluyó a 295 varones ≥ 65 años, residentes en Salamanca capital, de forma libre y gratuita. Se excluyeron aquellos con aneurisma aórtico conocido. Se realizaron: 1) registro de datos; 2) eco Doppler color por especialistas en angiología y cirugía vascular, y 3) encuesta de satisfacción. Todos firmaron un consentimiento informado. Resultados: el diámetro transversal medio de la aorta abdominal fue de 1,81 ± 0,36 cm. Se detectaron 2 aneurismas (diámetro mayor: ≥ 3,0 cm; 3,1 y 4,7 cm) y 3 ectasias aórticas (diámetro ≥ 2,5 y < 3,0 cm). El 98,3 % (290 varones) no presentó ectasia o aneurisma (aorta < 2,5 cm). Tres individuos (obesidad o aire intrabdominal) fueron reevaluados posteriormente. Se analizaron los factores de riesgo y los antecedentes de la población cribada. 180 participantes del cribado (61,0 %) rellenaron anónimamente una encuesta de satisfacción, con resultados muy positivos. Conclusión: si bien el rendimiento de detección fue bajo, la estrategia y el método empleado fueron satisfactorios para el equipo explorador y la población explorada. Este estudio piloto nos permitirá planificar y organizar un segundo cribado más amplio y de nuevos objetivos.(AU)

Introduction: a strategy to reduce the mortality of abdominal aortic aneurysms is to know their existence in theasymptomatic phase. This way we can classify patients, mainly according to the size of the aneurysm, into candi-dates for scheduled elective surgery or periodic follow-up.Objectives: to determine the effectiveness, safety, and acceptability of a pilot screening program for abdominalaortic aneurysms, using abdominal ultrasound, performed in a risk population.Material and methods: program organized by the Royal Academy of Medicine and the Biomedical ResearchInstitute, and carried out by the Angiology and Vascular Surgery service of the University Hospital of Salamanca.The screening was carried out a year ago, in two tents located in a central square in Salamanca. The study included295 men over 65 years of age, residents of Salamanca capital, free of charge. Those with known aortic aneurysmwere excluded. The following were carried out: 1) data recording; 2) color echo-Doppler, by specialists in angiologyand vascular surgery; and 3) satisfaction survey. All signed an informed consent.Results: the mean transverse diameter of the abdominal aorta was 1.81 ± 0.36 cm. Two aneurysms were detect-ed (largest diameter ≥ 3.0 cm; 3.1 and 4.7 cm), and 3 aortic ectasias (diameter ≥ 2.5 and < 3.0 cm). The 98.3 %(290 men) did not present ectasia or aneurysm (aorta < 2.5 cm). Three individuals (obesity or intra-abdominal air) weresubsequently re-evaluated. The risk factors and background of the screened population were analyzed. A satisfactionsurvey was completed freely and anonymously by 180 screening participants (61.0 %) with very positive results.Conclusion: although the detection performance was low, the strategy and method used were satisfactory for theexploring team and the population explored. The present pilot study will allow us to plan and organize a second,broader screening with new objectives.(AU)

Aedv expert consensus for the management of syphilis. / Documento de expertos de la aedv para el manejo de la sífilis.

Syphilis-the "great simulator" for classical venereologists-is re-emerging in Western countries despite adequate treatment; several contributing factors have been identified, including changes in sexual behaviour, which won't be the topic of this article though. In 2021, a total of 6613 new cases of syphilis were reported in Spain, representing an incidence of 13.9 x 100 000 inhabitants (90.5%, men). Rates have increased progressively since 2000. The clinical presentation of syphilis is heterogeneous. Although chancroid, syphilitic roseola and syphilitic nails are typical lesions, other forms of the disease can be present such as non-ulcerative primary lesions like Follmann balanitis, chancres in the oral cavity, patchy secondary lingual lesions, or enanthema on the palate and uvula, among many others. Regarding diagnosis, molecular assays such as PCR have been replacing dark-field microscopy in ulcerative lesions while automated treponemal tests (EIA, CLIA) are being used in serological tests, along with classical tests (such as RPR and HAART) for confirmation and follow-up purposes. The interpretation of these tests should be assessed in the epidemiological and clinical context of the patient. HIV serology and STI screening should be requested for anyone with syphilis. Follow-up of patients under treatment is important to ensure healing and detect reinfection. Serological response to treatment should be assessed with the same non-treponemal test (RPR/VDRL); 3-, 6-, 12-, and 24-month follow-up is a common practice in people living with HIV (PLHIV). Sexual contacts should be assessed and treated as appropriate. Screening is advised for pregnant women within the first trimester of pregnancy. Pregnant women with an abortion after week 20 should all be tested for syphilis. The treatment of choice for all forms of syphilis, including pregnant women and PLHIV, is penicillin. Macrolides are ill-advised because of potential resistance.

TREATMENT OF SUPRACONDYLAR FEMORAL FRACTURES BY MINIMALLY INVASIVE TECHNIQUES VS. EXPOSURE OF THE FRACTURE SITE: A RETROSPECTIVE COHORT STUDY. / TRATAMIENTO DE FRACTURAS SUPRACONDÍLEAS DE FÉMUR MEDIANTE TÉCNICAS MÍNIMAMENTE INVASIVAS VS EXPOSICIÓN DEL FOCO DE FRACTURA: UN ESTUDIO DE COHORTES RETROSPECTIVAS.

INTRODUCTION: Fractures of the distal femoral third are an important cause of morbidity and mortality, and their treatment is currently controversial. OBJECTIVES: To compare the results between minimally invasive techniques versus exposure of the fracture site. Secondly, to evaluate the relationship between demographic factors, mechanism of injury and surgical delay with patient prognosis. METHOD: Retrospective cohort study carried out between 2015 and 2021 in a tertiary hospital. Data collection was performed by reviewing medical histories, measuring demographic and hospital parameters and definitive treatment strategy. One year of follow-up was completed in all patients, assessing the occurrence of surgical complications and mortality. A stratified analysis of the variables of interest was performed among patients over 65 years of age. RESULTS: 128 fractures were recorded, with definitive osteosynthesis being performed in 117. Patients who underwent minimally invasive techniques required a shorter hospital stay (9 [7-12] vs 12 [8.75-16] days) (p=0.007), with no differences in mortality or complications during follow-up. In those over 65 years of age, opening the fracture site was associated with an increased risk of infection compared to minimally invasive techniques (33.3% vs 2%) (p=0.507). All the deceased were patients over 65 years of age (33.7% at one year). Surgical delay longer than 48 hours increased mortality by 10% among those older than 65 years (p=0.3). High-energy trauma had a higher proportion of pseudarthrosis (27.6% vs 6.1%) (p=0.011). CONCLUSIONS: Minimally invasive techniques decreased hospital stay but not complications or long-term mortality. LEVEL OF EVIDENCE: IIb.

Infectious keratitis associated with contact lens wear: REGINFECOR multicenter study.

This 32-centre multicentre study addresses the lack of knowledge about the prevalence and significance of microbial keratitis (MK) associated with contact lens (CL) wear in Spain. A total of 304 cases recruited from 32 hospitals were studied and showed that infectious keratitis associated with contact lens wear mainly affects young women during the summer months. In this study, soft lenses with monthly replacement and single solution cleaning were most commonly used, purchased and fitted in opticians' shops. Common risk factors were identified among users, such as topping off solutions, prolonging the life of lenses, and frequently sleeping, swimming and showering with lenses. Overnight lens wear was significantly associated with a higher incidence of corneal opacities, and the presence of Pseudomonas aeruginosa in bacterial cultures was associated with more severe sequelae and a greater need for corneal transplantation. Although most cases were benign, the time taken to heal was long, which poses a problem for working patients. This study provides valuable epidemiological, microbiological and risk factor information and estimates the incidence of CL related MK in Spain to be approximately 1 case per 30,000 inhabitants per year.

Total hip arthroplasty with second generation dual mobility system as a treatment for primary coxarthrosis, medium-term results. / Artroplastia total de cadera con sistema de doble movilidad de segunda generación como tratamiento de coxartrosis primaria, resultados a mediano plazo.

INTRODUCTION: Osteoarthritis is a disabling pathology characterized by joint pain and stiffness. A prevalence of coxarthrosis of 7.4% is reported in our country. Total hip joint replacement is indicated in advanced stages, a procedure that is not free of complications, the most frequent being prosthetic dislocation, which can be prevented with dual mobility systems. The following study aims to determine the rate of complications and clinical outcomes in dual mobility systems in primary coxarthrosis. MATERIALS AND METHODS: A retrospective study included 120 cases in 114 patients diagnosed with grade III coxarthrosis, mean age was 62.43 years, with a mean follow-up of 4.5 years. Joint replacement was performed by Hardinge approach. All cases were assessed clinically using the Harris Hip Score (HHS) and radiologically to demonstrate mid-term results. RESULTS: The preoperative value on the HHS scale had a mean of 56.45, postoperative at one month 74.23; 6 months 85.40; 1 year 94.01 and at 5 years 94.84 points, representing a functional improvement of 17.78 postoperative month; 28.95 at 6 months postoperative; 37.56 at one year postoperative and 38.39 points at 5 years postoperative. A complication rate of 3.44%; 0.86% of complications were associated with the prosthetic components. CONCLUSION: The dual mobility system should be considered as a therapeutic option in primary hip joint replacement due to excellent functional results and low complication rates. EVIDENCE LEVEL: IV. Retrospective observational case series study.

Uso de antipsicóticos en los pacientes con demencia en España: comparación con la prescripción de los inhibidores de la acetilcolinesterasa y de la memantina, y análisis de las asociaciones / Use of antipsychotics in patients with dementia in Spain: Comparison with prescription of acetylcholinesterase inhibitors and memantine and analysis of associations

Objetivo: Se ha analizado la prevalencia de antipsicóticos, inhibidores de la acetilcolinesterasa (IACE) y memantina en pacientes con demencia en España y la influencia de estas asociaciones en su prescripción. Método: Estudio descriptivo, retrospectivo y transversal de la base BIFAP de 2017 en los mayores de 65 años con demencia. Se recogieron las prescripciones de antipsicóticos, los IACE y la memantina. Para los antipsicóticos también se recogieron, la duración del tratamiento y el tiempo desde el diagnóstico de demencia, al de prescripción. Resultados: Se recuperaron 1.327.792 sujetos, 89.464 (6,73%) con demencia. El 31,76% tuvieron prescritos antipsicóticos; los más frecuentes: quetiapina (58,47%), risperidona (21%) y haloperidol (19,34%). Las prescripciones de IACE y memantina fueron más frecuentes en los menores de 84 años y las de antipsicóticos en los mayores de 85 años (p<0,001). Los antipsicóticos se mantuvieron una media de 1.174,5 días. En el 26,4% de los casos se prescribieron aislados, OR: 0,61 (IC 95%: 0,59-0,62), en el 35,85% asociados a IACE, OR: 1,26 (IC 95%: 1,22-1,30) y en el 42,4% a memantina, OR: 1,69 (IC 95%: 1,62-1,78); p<0,000). Desde el diagnóstico de demencia transcurrieron de 461 días (±1.576,5) cuando se prescribieron aislados; 651 días (±1.574,25) asociados a IACE y 1.224 (±1.779) a memantina. Conclusiones: Una tercera parte de los pacientes con demencia tuvieron prescritos antipsicóticos, mayoritariamente atípicos, más frecuentemente en los mayores de 85 años y durante periodos prolongados. La prescripción de IACE y memantina se asoció al incremento del riesgo de uso de antipsicóticos, pero paradójicamente, a la prolongación del tiempo hasta su prescripción.(AU)

ObjectiveWe have analyzed the prevalence of antipsychotics in patients with dementia in Spain, their age distribution and the influence of treatment with IACEs and memantine on their prescription. Method: Descriptive, retrospective and cross-sectional study of the 2017 BIFAP database in over 65 years of age with dementia. Prescriptions of antipsychotics, IACEs and memantine were collected. For antipsychotics were also collected, the duration of treatment and time from dementia diagnosis to prescription. Results: A total of 1,327,792 subjects were retrieved, 89,464 (6.73%) with dementia. Antipsychotics were prescribed in 31.76%; by frequency: quetiapine (58.47%), risperidone (21%) and haloperidol (19.34%). Prescriptions of IACEs and memantine were clustered in those younger than 84 years and antipsychotics in those older than 85 (P<.001). Antipsychotics were maintained for a mean of 1174.5 days. In 26.4% of cases they were prescribed alone, OR 0.61 (95% CI: 0.59-0.62), in 35.85% associated with IACEs, OR 1.26 (95% CI: 1.22-1.30) and in 42.4% with memantine, OR 1.69 (95% CI: 1.62-1.78) (P<.000). From the diagnosis of dementia, 461 days (±1576.5) elapsed when isolated drugs were prescribed; 651 days (±1574.25) associated with IACEs and 1224 (±1779) with memantine. Conclusions: One third of patients with dementia were prescribed antipsychotics, mostly atypical, more frequently in those older than 85 years and for prolonged periods. IACEs and memantine were associated with the risk of antipsychotic prescription, but paradoxically, with prolonged time to onset.(AU)

Melanoma Registry of the Spanish Academy of Dermatology and Venereology (REGESMEL): Description and Data in its First Year of Operation. / Registro de Melanoma de la Academia Española de Dermatología y Venereología (REGESMEL): descripción y datos en el primer año de funcionamiento.

INTRODUCTION: The incidence of melanoma is rising in Spain. The prognostic stages of patients with melanoma are determined by various biological factors, such as tumor thickness, ulceration, or the presence of regional or distant metastases. The Spanish Academy of Dermatology and Venereology (AEDV) has encouraged the creation of a Spanish Melanoma Registry (REGESMEL) to evaluate other individual and health system-related factors that may impact the prognosis of patients with melanoma. The aim of this article is to introduce REGESMEL and provide basic descriptive data for its first year of operation. METHODS: REGESMEL is a prospective, multicentre cohort of consecutive patients with invasive cutaneous melanoma that collects demographic and staging data as well as individual and healthcare-related baseline data. It also records the medical and surgical treatment received by patients. RESULTS: A total of 450 cases of invasive cutaneous melanoma from 19 participant centres were included, with a predominance of thin melanomas≤1mm thick (54.7%), mainly located on the posterior trunk (35.2%). Selective sentinel lymph node biopsy was performed in 40.7% of cases. Most cases of melanoma were suspected by the patient (30.4%), or his/her dermatologist (29.6%). Patients received care mainly in public health centers (85.2%), with tele-dermatology resources being used in 21.6% of the cases. CONCLUSIONS: The distribution of the pathological and demographic variables of melanoma cases is consistent with data from former studies. REGESMEL has already recruited patients from 15 Spanish provinces and given its potential representativeness, it renders the Registry as an important tool to address a wide range of research questions.

Basal Cell Carcinoma: Incidence and Trends in Valencia, Spain. / Carcinoma basocelular: incidencia y tendencias en Valencia (España).

BACKGROUND: There is a need for epidemiological and incidence data on the occurrence of basal cell carcinoma (BCC) in Spain. OBJECTIVES: Our study was designed to retrospectively retrieve cases from our computer databases from 2010 through 2016 to provide updated data on the actual incidence of BCC in Valencia, eastern Spain. MATERIAL AND METHODS: This was an epidemiological study on basal cell carcinoma conducted in Valencia, eastern Spain. We analyzed a total of 2171 patients and 4047 tumors, and gathered data to estimate the actual incidence of BBC in our region. RESULTS AND CONCLUSIONS: Our study confirmed that the incidence of BCC is much higher than previously reported. We calculated a crude incidence of 410.38 BCCs/100 000 person-years, an adjusted rate for the European population of 256.98 BCCs/100 000 person-years, and an adjusted rate for the world population of 196.26 BCCs/100 000 person-years. Risk is up to 29.49% higher for men (464.07 cases/100 000 person-years vs 358.40 cases/100 000 person-years for women). Incidence also increases by an annual 3.91% (a significantly higher annual incidence of 8.28% in women vs a 0.92% annual incidence in men). Overall, the lifetime risk for developing a BCC is 5.8% (5.02% in women and 7% in men).
