Sex-Related Differences in Life Expectancy Compared to General Population after Surgery for Ascending Aortic Aneurysm.

Background/Objectives: Understanding sex-based differences in cardiovascular outcomes is paramount to improving clinical outcomes. Surgery is an aggressive but effective therapy for ascending aortic aneurysm. We sought to determine if being a woman is a risk factor for long-term mortality after this surgery. We compared their life expectancy with a general population of the same age, sex, year, and region. Methods: We compared men and women undergoing AAA surgery at our institution from 2000 to 2019. After balancing the population with propensity score (PS) matching, we compared long-term mortality control with a Cox regression. We determined the RS using the Ederer II method and compared it to a healthy reference population of the same age, sex, and region. Results: From 2000 to 2019, 232 women and 506 men underwent ascending aortic aneurysm surgery. After a mean follow-up of 51.5 ± 34.5 months, sex was not an independent risk factor for long-term mortality in the multivariable analysis [HR: 0.68 (95% CI 0.43-1.07, p = 0.23)]. Matching by baseline characteristics, 196 pairs were analyzed with no differences regarding mortality in the Cox regression [HR: 1.11 (95% CI 0.65-1.9, p = 0.23)]. Men and women who survived the postoperative period presented a relative survival of 100.3% (95% CI 97.4-101%) and 100.3% (95% CI 98.9-101.1%), respectively, similar to the reference population without the disease. Conclusions: For patients undergoing AAA surgery, sex was not an independent predictor of mortality. Men and women who survived the postoperative period presented a similar life expectancy to that of the reference population (people free from the disease of the same age, sex, year, and region).

Persistency of catastrophic out-of-pocket health expenditures: Measurement with evidence from three African countries - Malawi, Tanzania, and Uganda.

Catastrophic out-of-pocket health expenditure (CHE) remain high in Sub-Saharan Africa and may not conform to the sporadic random pattern of acute illnesses that shapes insurance arrangements intended to avoid the risk of financial loss. The persistency of CHE remains a largely unexplored issue due to the lack of relevant methods and scarcity of panel data. This paper addresses the first shortcoming by presenting three different approaches to incorporating the timeframes into the analysis, considering dynamics between two periods, average over time and the recurrence of CHE incidence. Through the application of the complementary approaches, we identify (i) those at risk of persistent CHE in the short-term; (ii) those facing transient versus persistent CHE in the long-term; and (iii) those facing multiple CHE spells. The methods are applied to different definitions of CHE using panel data from three sub-Saharan countries: Malawi (3 waves: 2010, 2013, and 2016) with 4983 observations; Tanzania (3 waves: 2008, 2010, and 2012) with 8715 observations; and Uganda (5 waves: 2009, 2010, 2011, 2013, and 2015) with 6475 observations. All datasets are balanced panels. Additionally, we employ empirical strategies to identify the underlying factors contributing to these persistent and relatively high OOP. Across the three countries, we find that at least 27% of the people facing CHE in one period, because they spent more than 5% of their household budget on health out-of-pocket, will face it again in the next period. The lower-bound risk for those spending more than 10% of their household budget is 9% and for those spending more than 25% of their household capacity to pay is 13%. Between 11% and 45% of the population incurred CHE at least twice during the observation period when using the 5% budget definition of CHE. The double recurrence rate ranges between 7% and 13% when using the 25% capacity-to-pay definition and between 3% and 20% when using the 10% budgetshare definition. Between 22% and 32% of the population experienced chronic CHE at the 5% of the budgetshare definition (6%-10% at the 10% of the budgetshare definition of CHE; 2%-11% at 25% of capacity-to-pay). Our panel regression analysis consistently highlights the susceptibility of certain groups to face persistence CHE, notably those residing in rural areas, individuals with lower levels of education, the elderly, and those who have undergone hospitalizations.

Cardiopulmonary Complications after Pulmonary Embolism in COVID-19.

Although pulmonary embolism (PE) is a frequent complication in COVID-19, its consequences remain unknown. We performed pulmonary function tests, echocardiography and computed tomography pulmonary angiography and identified blood biomarkers in a cohort of consecutive hospitalized COVID-19 patients with pneumonia to describe and compare medium-term outcomes according to the presence of PE, as well as to explore their potential predictors. A total of 141 patients (56 with PE) were followed up during a median of 6 months. Post-COVID-19 radiological lung abnormalities (PCRLA) and impaired diffusing capacity for carbon monoxide (DLCOc) were found in 55.2% and 67.6% cases, respectively. A total of 7.3% had PE, and 6.7% presented an intermediate-high probability of pulmonary hypertension. No significant difference was found between PE and non-PE patients. Univariate analysis showed that age > 65, some clinical severity factors, surfactant protein-D, baseline C-reactive protein, and both peak red cell distribution width and Interleukin (IL)-10 were associated with DLCOc < 80%. A score for PCRLA prediction including age > 65, minimum lymphocyte count, and IL-1ß concentration on admission was constructed with excellent overall performance. In conclusion, reduced DLCOc and PCRLA were common in COVID-19 patients after hospital discharge, but PE did not increase the risk. A PCRLA predictive score was developed, which needs further validation.

Plasma levels of complement components C5 and C9 are associated with thrombin generation.

BACKGROUND: The thrombin generation assay (TGA) evaluates the potential of plasma to generate thrombin over time, providing a global picture of an individual's hemostatic balance. OBJECTIVES: This study aimed to identify novel biological determinants of thrombin generation using a multiomics approach. METHODS: Associations between TGA parameters and plasma levels of 377 antibodies targeting 236 candidate proteins for cardiovascular risk were tested using multiple linear regression analysis in 770 individuals with venous thrombosis from the Marseille Thrombosis Association (MARTHA) study. Proteins associated with at least 3 TGA parameters were selected for validation in an independent population of 536 healthy individuals (Etablissement Français du Sang Alpes-Méditerranée [EFS-AM]). Proteins with strongest associations in both groups underwent additional genetic analyses and in vitro experiments. RESULTS: Eighteen proteins were associated (P < 1.33 × 10⁻4) with at least 3 TGA parameters in MARTHA, among which 13 demonstrated a similar pattern of associations in EFS-AM. Complement proteins C5 and C9 had the strongest associations in both groups. Ex vivo supplementation of platelet-poor plasma with purified C9 protein had a significant dose-dependent effect on TGA parameters. No effect was observed with purified C5. Several single nucleotide polymorphisms associated with C5 and C9 plasma levels were identified, with the strongest association for the C5 missense variant rs17611, which was associated with a decrease in C5 levels, endogenous thrombin potential, and peak in MARTHA. No association of this variant with TGA parameters was observed in EFS-AM. CONCLUSION: This study identified complement proteins C5 and C9 as potential determinants of thrombin generation. Further studies are warranted to establish causality and elucidate the underlying mechanisms.

Combined PIK3CA and SOX2 Gene Amplification Predicts Laryngeal Cancer Risk beyond Histopathological Grading.

The PIK3CA and SOX2 genes map at 3q26, a chromosomal region frequently amplified in head and neck cancers, which is associated with poor prognosis. This study explores the clinical significance of PIK3CA and SOX2 gene amplification in early tumorigenesis. Gene copy number was analyzed by real-time PCR in 62 laryngeal precancerous lesions and correlated with histopathological grading and laryngeal cancer risk. Amplification of the SOX2 and PIK3CA genes was frequently detected in 19 (31%) and 32 (52%) laryngeal dysplasias, respectively, and co-amplification in 18 (29%) cases. The PIK3CA and SOX2 amplifications were predominant in high-grade dysplasias and significantly associated with laryngeal cancer risk beyond histological criteria. Multivariable Cox analysis further revealed PIK3CA gene amplification as an independent predictor of laryngeal cancer development. Interestingly, combined PIK3CA and SOX2 amplification allowed us to distinguish three cancer risk subgroups, and PIK3CA and SOX2 co-amplification was found the strongest predictor by ROC analysis. Our data demonstrate the clinical relevance of PIK3CA and SOX2 amplification in early laryngeal tumorigenesis. Remarkably, PIK3CA amplification was found to be an independent cancer predictor. Furthermore, combined PIK3CA and SOX2 amplification is emerging as a valuable and easy-to-implement tool for cancer risk assessment in patients with laryngeal precancerous lesions beyond current WHO histological grading.

Del total de artículos, 6 corresponden a terapia láser de bajo nivel, 2 a medicación y bloqueo del ganglio estrellado, 1 a bloqueo de ganglio estrellado e irradiación con luz xenón y 5 artículos corresponden a tratamiento mediante reparación microquirúrgica. La terapia láser de bajo nivel, el bloqueo del ganglio estrellado, la administración de vitamina B12/ATP y la reparación microquirúrgica son tratamientos efectivos para las alteraciones neurosensoriales ocasionadas por lesiones del nervio alveolar inferior y nervio lingual.

SUMMARY: Neurosensory abnormalities are complications can occur after performing certain oral surgical procedures. Multiple reports specifically indicate the area innervated by the inferior alveolar nerve and the lingual nerve as the most affected regions. Presenting the different therapeutic alternatives for these complications would be extremely relevant for the clinician, in order to improve the prognosis in terms of neurosensory recovery of these nerves. The objective of this study was to describe the therapeutic management of neurosensory abnormalities associated with damage to the inferior alveolar nerve and lingual nerve, in mandibular surgical procedures. The search for scientific literature was carried out in the PubMed, Scopus and Web of Science databases. The search terms "Trigeminal nerve injuries", "lingual nerve", "mandibular nerve", "oral surgical procedures", "treatment" together with the boolean connector "AND" and "OR" were used. Articles published between the years 2012 and 2022 were considered. In the selection of primary articles, duplicates were eliminated and the inclusion and exclusion criteria were applied. Finally, the full text analysis was carried out with a total of 14 selected articles. A total of 14 articles were reviewed. About the articles, 6 correspond to low-level laser therapy, 2 to medication and stellate ganglion block, 1 to stellate ganglion block and xenon light irradiation, and 5 articles correspond to treatment by microsurgical repair. Low-level laser therapy, stellate ganglion block, vitamin B12/ATP administration, and microsurgical repair are effective treatments for neurosensory abnormalities caused by inferior alveolar nerve and lingual nerve injuries.

Resultados a corto y medio plazo de la reparación transcatéter de la válvula tricúspide: revisión sistemática y metanálisis de estudios observacionales / Early and mid-term outcomes of transcatheter tricuspid valve repair: systematic review and meta-analysis of observational studies

Introducción y objetivos La insuficiencia tricuspídea (IT) se asocia con un peor pronóstico si no se corrige. Se han publicado recientemente numerosos estudios sobre reparación transcatéter de la válvula tricúspide (RTT) Métodos Se llevó a cabo una revisión sistemática de estudios que publican datos clínicos de pacientes con IT significativa sometidos a RTT. Se evaluaron objetivos clínicos y ecocardiográficos a corto y medio plazo. Las razones de riesgo (RR) y las diferencias de medias (DM) se obtuvieron de la comparación de datos previos y posteriores a la intervención. Se hizo también un análisis de sensibilidad según el abordaje principal (reparación borde a borde frente a anuloplastia) Resultados Se incluyeron 19 estudios (todos observacionales o ensayos de un solo grupo) con un total de 991 pacientes sometidos a RTT sola. Las tasas de mortalidad e ictus a 30 días fueron del 2,8 y el 0,2% respectivamente. El análisis agrupado de efectos aleatorios mostró una reducción significativa de IT (RR=0,33; IC95%, 0,26-0,42; p <0,001), vena contracta (DM, 5,9mm; IC95%, 4-7,9; p <0,001), diámetro telediastólico del ventrículo derecho (DM, 3,5mm; IC95%, 2,5-4,5; p <0,001) y clase funcional de la NYHA 3 o 4 (RR=0,32; IC95%, 0,27-0,37; p <0,001) a los 30 días. Las complicaciones hemorrágicas y la IT residual al menos grave fueron numéricamente superiores en el grupo de anuloplastia percutánea en comparación con el grupo de reparación borde a borde (hemorragias, el 13,3 y el 2,8%; IT residual, el 40,4 y el 27,9%) Conclusiones En los 991 pacientes que formaron parte de la experiencia inicial de RTT, tras la intervención se observó una reducción estadísticamente significativa del grado de IT grave o peor, una mala clase funcional (NYHA 3-4), la anchura de la vena contracta y el diámetro telediastólico del ventrículo derecho. Hasta ahora, el abordaje con reparación borde a borde parece tener un mejor perfil de seguridad (AU)

Introduction and objectives Severe tricuspid regurgitation (TR) is associated with poor prognosis when left untreated, and a growing number of studies on transcatheter tricuspid valve repair (TTVr) have been published over the last few months. Methods We performed a comprehensive systematic review of published literature providing clinical data on TTVr for patients with significant TR. Early and mid-term clinical and echocardiographic outcomes were evaluated. Risk ratios (RR) or mean differences (MD) were obtained when comparing pre- and postprocedural data. A sensitivity analysis was also performed according to the main approach for repair (edge-to-edge vs annuloplasty). Results A total of 19 studies (all observational or single-arm trials) and 991 patients who underwent isolated TTVr were included. Thirty-day mortality and stroke rates were 2.8% and 0.2%, respectively. Pooled random-effects resulted in a significant reduction of ≥ severe TR (RR, 0.33; 95%CI, 0.26-0.42; P<.001), vena contracta width (MD, 5.9mm; 95%CI, 4-7.9; P <.001), right ventricular end-diastolic diameter (MD, 3.5mm; 95%CI, 2.5-4.5; P <.001), and New York Heart Association (NYHA) class III or IV at last follow-up (RR, 0.32; 95%CI, 0.27-0.37; P <.001). Bleeding complications and residual ≥ severe TR were numerically higher in the annuloplasty-like group compared with edge-to-edge repair (13.3% vs 3.8% for bleeding and 40.4% vs 27.9% for residual severe TR). Conclusions Among 991 patients comprising the early experience for several TTVr devices, there was a statistically significant reduction in ≥ severe TR, NYHA class III-IV, vena contracta width and right ventricular end-diastolic diameter after TTVr. Thus far, the edge-to-edge approach seems to be associated with a better safety profile (AU)

Objetivos. Analizar la desigualdad de género en la producción científica de la revista EMERGENCIAS en la última década. Método. Estudio longitudinal retrospectivo que revisó los números publicados entre enero de 2011 y diciembre de 2020. Se analizaron el número de autores, género, tipo y año de publicación y autoría preferencial (primera autoría, autoría de correspondencia o última autoría). La participación de la mujer se calculó en base a valores porcentuales y se analizó la tendencia existente a lo largo de los años. Resultados. Se recogieron 1.240 artículos con un número total de 5.213 firmantes, 1.889 de ellos (36,2%) mujeres. En 384 (31%) artículos, una mujer asumió la primera autoría, en 352 (28,4%) fue autora para correspondencia y en 358 (28,9%) la última autora. A lo largo de la década, se identificó una tendencia creciente en los que una mujer fue primera autora en los artículos originales o metanálisis (p = 0,047). En los editoriales, revisiones, cartas científicas o comunicaciones breves, cartas al editor y otros no existió una tendencia creciente significativa en las autorías preferenciales. Conclusión. La participación de autoras en la producción científica de la revista EMERGENCIAS ha aumentado en la última década. No obstante, comparado con la de hombres, sigue existiendo una menor participación. (AU)

Objective. To analyze gender disparity in scientific productivity reflected by the authorship of articles in the journal Emergencias over the past decade. Methods. Retrospective longitudinal study. We included articles in all issues published between January 2011 and December 2020, analyzing the number of authors, their gender, article type, year of publication, and preferential authorship credit (first author, corresponding author, and last author positioning). The percentages of women named in each position were calculated, and the trend over time was analyzed. Results. A total of 1240 articles signed by 5213 authors were collected; a woman was named in 1889 of the cases (36.2%). A woman was the first author of 384 articles (31%), the corresponding author of 352 (28.4%), and the last author of 358 (28.9%). The number of female authors of original research articles or meta-analyses tended to increase over time (P = .047), but no statistically significant gender trends were observed in the authorship of editorials, narrative reviews, scientific letters or short communications, letters to the editor, or any other publication category. Conclusions. The publication of articles by women in Emergencias has increased over the past decade. However, women continue to author fewer articles than men. (AU)

“¿Entiendes ahora por qué estoy así?” Formulación psicológica de un caso desde el Marco de Amenaza, Poder y Significado / Do you understand why I am like this?” Psychological formulation from the Power Threat Meaning Framework: A case report

Este artículo analiza un caso clínico desde el recientemente aparecido Marco de Poder, Amenaza y Significado. Se presentan las conceptualizaciones básicas de este modelo y los factores de análisis que proponen: poder, amenaza, significado y respuesta a la amenaza. Por medio de estos se realiza un análisis retrospectivo del caso y se proponen nuevas líneas de conceptualización e intervención inexploradas hasta el momento, basadas en la comprensión de las respuestas a la amenaza como formas de supervivencia y realizando modificaciones en su narrativa hacia una que le permita entender y gestionar su sufrimiento, pasando de la desesperanza a la agencialidad.

This article analyzes one clinical case from the recently published Power, Threat and Meaning Freamwork. The basic conceptualizations of this model and the analysis factors that they propose are presented: power, threat, meaning and response to the threat. Through these, a retrospective analysis of the case is carried out and new lines of conceptua-lization and intervention unexplored until now are proposed, based on the understanding of the responses to the threat as forms of survival and making modifications in their narrative towards one that allows them to understand and manage their suffering, moving from hopelessness to agency.

Incidencia de infección por SARS-COV-2 en pacientes con un trasplante renal funcionante en un hospital terciario de la Comunidad de Madrid / Incidence of SARS-CoV-2 infection in patients with a functioning renal transplant in a tertiary hospital in the community of Madrid

En diciembre de 2019, apareció un nuevo coronavirus que ha dado lugar a una pandemia. Dadas las características del paciente trasplantado, se hace necesario conocer cuál ha sido la repercusión respecto a la infección por SARS-CoV-2, planteándonos como objetivo describir la incidencia de SARS-CoV-2 en pacientes con un trasplante renal.Se llevó a cabo un estudio observacional de cohorte retrospectiva de pacientes con un trasplante renal y que están en seguimiento por la consulta de trasplantes de un hospital terciario, durante el periodo comprendido entre el 1 de marzo de 2020 y el 1 de marzo de 2021. Se incluyeron 604 individuos, con una edad media de 61,6±12,8 años. Un 62,3% (n=376) fueron hombres. La incidencia por SARS-CoV-2 fue 14,9% (n=90). La mortalidad por SARS-CoV-2 fue 3,8% (n=23) lo que supone una letalidad del 25,5%. Al comparar si han pasado la infección en función del sexo no se encontraron diferencias significativas. Tampoco al comparar en función de la edad media, que fue de 60,9±11,8 años en los infectados y de 61,7±12,9 años en los no infectados. Se encontraron diferencias significativas (p=0,005) al comparar la media de años transcurridos desde el trasplante; que fue de 8,7±5,6 años en los infectados y de 11 ±7,3 años en los no infectados.La incidencia de infección por SARS-CoV-2 encontrada en personas con TR fue muy superior a la descrita para la población general. La letalidad y la mortalidad también fueron mayores que en la población general, pero acordes con otras poblaciones de individuos con TR. (AU)

In December 2019, a new coronavirus appeared and generated a pandemic. Considering the characteristics of the transplanted patient, it is relevant to know the impact regarding SARS-CoV-2 infection, aiming to describe the incidence of SARS-CoV-2 in renal transplant patients.A retrospective observational cohort study of patients with a renal transplant and under follow-up by the transplant clinic of a tertiary hospital was conducted during the period from 1 March 2020 to 1 March 2021. A total of 604 individuals were included, with a mean age of 61.6 ±12.8 years. 62.3% (n=376) were men.SARS-CoV-2 incidence was 14.9% (n=90). Mortality due to SARS-CoV-2 was 3.8% (n=23), giving a case fatality of 25.5%. No significant differences were found according to sex and age, being 60.9±11.8 years in those infected and 61.7±12.9 years in those not infected. Significant differences (p=0.005) were found for the mean number of years since transplantation; 8.7±5.6 years in those infected and 11±7.3 years in those not infected.The incidence of SARS-CoV-2 infection in renal transplant recipients was much higher than that described for the general population. Case fatality and mortality were also higher than in the general population, but in line with other series of individuals with renal transplantation. (AU)

Análisis de riesgo de un microorganismo objetable en un suplemento dietario para la liberación de lotes

RESUMEN La contaminación con microorganismos objetables en los productos farmacéuticos no estériles puede tener el potencial de disminuir o inactivar la actividad farmacológica y terapéutica del principio activo y por ende representar un peligro de gran riesgo para la salud de la persona que está en tratamiento con fármacos; adicionalmente la presencia de estos microorganismos dependiendo de su capacidad para producir enfermedad en huéspedes susceptibles pueden ocasionar infecciones no esperadas o enfermedades que afecten al paciente o consumidor de estos medicamentos no estériles. El objetivo del trabajo fue desarrollar un análisis de riesgo microbiológico de microorganismos objetables en un suplemento dietario de una industria farmacéutica como herramienta en la gestión de seguridad. La metodología fue observacional-descriptivo de corte transverso. En la industria farmacéutica (en el suplemento dietario) se desarrolló un análisis de riesgo estudiando todos los parámetros, teniendo como resultado, que las cápsulas blandas con aceite de Krill, no presentan microorganismo objetable del tipo patógeno, como producto de bajo riesgo, por lo que es aprobado para la liberación del lote siguiendo estos parámetros. En Paraguay no existen normativas acerca del análisis de microorganismos objetables, en comparación con otros países como Argentina, y desde hace tiempo en EE. UU y países europeos (por reportes de la FDA) por lo cual, este trabajo es relevante y de vital importancia para establecer legislaciones nacionales con miras a la fabricación de medicamentos seguros, confiables y eficaces.

ABSTRACT Contamination with objectionable microorganisms in non sterile pharmaceutical products may have the potential to decrease or inactivate the pharmacological and therapeutic activity of the active principle and therefore represent a danger of great risk to the health of the person who is being treated with drugs, additionally, the presence of these microorganisms, depending on their ability to produce disease in susceptible hosts, can cause unexpected infections or diseases that affect the patient or consumer of these non sterile drugs. The objective of the work was to develop a microbiological risk analysis of objectionable microorganisms in a dietary supplement of a pharmaceutical industry as a tool in safety management. This was an observational-descriptive cross-sectional study. In the pharmaceutical industry (in the dietary supplement) a risk analysis was developed studying all the parameters, having as a result that the soft capsules with Krill oil do not present objectionable microorganisms of the pathogenic type, as a low risk product, therefore it is approved for batch release following these parameters. In Paraguay there are no regulations about the analysis of objectionable microorganisms, in comparison with other countries such as Argentina, and for a long time in the US and European countries (due to FDA reports). Therefore, this work is relevant and very vital important to establish national legislation with a view of the manufacture of safe, reliable and effective drugs.

Expresión de E-cadherina y beta-catenina en carcinomas de células escamosas de laringe e hipofaringe / Expression of E-cadherin and Beta-catenin in Laryngeal and Hypopharyngeal Squamous Cell Carcinomas

INTRODUCCIÓN Y OBJETIVOS: La disfunción del complejo E-cadherina/catenina está relacionada directamente con la carcinogénesis y el desarrollo de metástasis. El objetivo de este trabajo es investigar el significado pronóstico de la expresión de E-cadherina y beta-catenina en carcinomas de células escamosas de laringe e hipofaringe tratados quirúrgicamente. MATERIAL Y MÉTODOS: Se obtuvieron muestras de tejido tumoral de 133 pacientes consecutivos con carcinomas escamosos de cabeza y cuello (68 de laringe y 65 carcinomas de hipofaringe), que fueron sometidos a tratamiento quirúrgico en nuestro hospital entre 2000 y 2005. La expresión de E-cadherina y beta-catenina se analizó mediante inmunohistoquímica, cuantificando el porcentaje de células teñidas y la intensidad de la tinción. RESULTADOS: La expresión de E-cadherina y beta-catenina fue evaluable en 59 muestras de carcinomas de laringe y en 58 de hipofaringe. En tumores de laringe se observó una asociación significativa entre la baja expresión de beta-catenina de membrana y tumores avanzados T4 y la recidiva tumoral. A nivel de hipofaringe se encontró una asociación significativa de la expresión positiva de Beta-catenina nuclear con pobre diferenciación histológica (p = 0,02). En el análisis multivariante solo la presencia de metástasis ganglionares era factor predictor independiente de disminución de la supervivencia específica para enfermedad en carcinoma de células escamosas de laringe. CONCLUSIONES: La expresión de E-cadherina y beta-catenina no parece tener utilidad pronóstica superior al TNM en los carcinomas epidermoides de laringe e hipofaringe

INTRODUCTION AND OBJECTIVES: Dysfunction of the E-cadherin/catenin complex is directly related to carcinogenesis and metastases development. The aim of this paper is to investigate the prognostic significance of E-cadherin and Beta-catenin expression in surgically treated laryngeal and hypopharyngeal squamous cell carcinomas. MATERIAL AND METHODS: Tumour tissue samples were obtained from 133 consecutive patients with squamous cell carcinomas of the head and neck: 68 of the larynx and 65 hypopharyngeal carcinomas, who underwent surgical treatment in our hospital between 2000 and 2005. E-cadherin and beta-catenin expression was analysed by immunohistochemistry, quantifying the percentage of stained cells and the intensity of staining. RESULTS: E-cadherin and beta-catenin expression was evaluable in 59 laryngeal carcinomas and in 58 cases of hypopharyngeal carcinomas. In the laryngeal tumours, a significant association was found between the low expression of membrane Beta-catenin with T4 tumours and tumour recurrence. In the hypopharynx there was a significant association between positive expression of nuclear beta-catenin and poor histological differentiation (P = .02). In the multivariate analysis, only the presence of lymph node metastases was an independent predictive factor of decreased disease-specific survival in laryngeal squamous cell carcinomas. CONCLUSIONS: The expression of E-cadherin and beta-catenin does not show prognostic significance in laryngeal and hypopharyngeal squamous cell carcinomas over the TNM classification

Supervivencia de los pacientes ancianos con implante percutáneo de válvula aórtica comparados con la población general / Survival in elderly patients with transcatheter aortic valve implants compared with the general population

INTRODUCCIÓN Y OBJETIVOS: La estenosis aórtica grave sintomática conlleva un pronóstico ominoso. El recambio percutáneo de válvula aórtica ha mostrado que cambia la historia natural de la enfermedad. Sin embargo, se desconoce si los pacientes mayores intervenidos recuperan una supervivencia similar a la de la población general. Nuestro objetivo es conocerlo. MÉTODOS: Se analizó de manera retrospectiva la curva de supervivencia de los pacientes mayores de 75 años intervenidos mediante implante percutáneo de válvula aórtica (TAVI) en nuestro centro y se comparó con la población general de iguales edad, sexo y región geográfica utilizando datos del Instituto Nacional de Estadística. RESULTADOS: Se analizó a 526 pacientes. Una vez superado el periodo posoperatorio, las curvas de supervivencia se igualaron durante la mayor parte del seguimiento. Las probabilidades de sobrevivir para los pacientes TAVI a los 1, 3, 5 y 8 años fueron del 90,58% (intervalo de confianza [IC] del 95%, 87,54-92,91), el 72,51% (IC95%, 67,38-76,97), el 53,23% (IC95%, 46,52-59,48) y el 35,73% (IC95%, 27,72-43,80). En la población de referencia fueron el 91,93, el 75,63, el 59,6 y el 37,47%. CONCLUSIONES: La supervivencia de los pacientes mayores intervenidos mediante TAVI está condicionada por la mortalidad posoperatoria. Los supervivientes al periodo posoperatorio recuperan una supervivencia similar a la de la población general de iguales edad, sexo y territorio

INTRODUCTION AND OBJECTIVES: Severe symptomatic aortic stenosis carries a very poor prognosis. Transcatheter aortic valve replacement has been demonstrated to change the natural history of the disease. However, it is not known whether the probability of survival in older patients receiving this treatment returns to a similar value to that in the general population. Our objective was to determine survival in these patients vs that in the general population. METHODS: We retrospectively analyzed the survival curves of patients older than 75 years who underwent transcatheter aortic valve implantation (TAVI) at our hospital and compared them with those in the general population of the same age, sex, and geographic region by using data from the Spanish National Institute of Statistics. RESULTS: We analyzed 526 patients. Among postoperative survivors, survival curves were similar between the 2 groups during most of the follow-up. In TAVI patients, the probability of survival at 1, 3, 5, and 8 years of follow-up was 90.58% (confidence interval [CI] 95%, 87.54-92.91), 72.51% (95%CI, 67.38-76.97), 53.23% (95%CI, 46.52-59.48), and 35.73% (95%CI, 27.72-43.80). In the reference population, these percentages were 91.93%, 75.63%, 59.6%, and 37.47%. CONCLUSIONS: Long-term survival in elderly patients undergoing TAVI is influenced by postoperative mortality. In patients surviving the postoperative period, the probability of survival returns to a similar value to that in the general population of the same age, sex, and geographical area

Rasgos de personalidad y variables asociadas a la ansiedad escénica musical / Personality traits and variables associated with music performance anxiety

INTRODUCCIÓN: La ansiedad escénica musical (AEM) es una sintomatología que afecta a un gran número de músicos y que afecta a su ejecución. Los rasgos de personalidad así como variables sociodemográficas parecen influir en este padecimiento. OBJETIVO: Analizar qué rasgos de personalidad influyen en la AEM y determinar si puede ser predicha por el sexo, la familia del instrumento practicado, actuar como solista o el tipo de formación recibida. Materia y método: La muestra estuvo compuesta por 72 músicos, entre 16 y 54 años (M = 24.11; DE = 9.03). Se les administró el KMPAI-E para medir la ansiedad escénica y el NEO-FFI para medir la personalidad. Se realizó una correlación bivariada y un análisis de regresión múltiple. RESULTADOS: Los resultados mostraron una correlación positiva entre la AEM y el neuroticismo (p < .01) y negativa con la extraversión (p < .01) y la responsabilidad (p < .05). Asimismo, se determinó como variables predictivas de la AEM, la familia instrumental y el sexo. Según el sexo, hubo diferencias significativas (p < .01) en AEM, siendo las mujeres quienes obtuvieron mayores puntuaciones. Respecto a la familia instrumental, existió diferencia significativa con la cuerda pulsada (p < .05). Ser solista y el tipo de formación no predijo la AEM. CONCLUSIONES: Una personalidad con tendencia al neuroticismo e introversión parece tener influencia en la AEM. Asimismo, el hecho de ser mujer y practicar los instrumentos de cuerda pulsada podrían predecir la AEM

INTRODUCTION: Music Performance Anxiety (MPA) is a symptomatology that affects a large number of musicians and their execution. Personality traits such as sociodemographic variables seem to influence this condition. OBJECTIVE: Analyze which personality traits influence the MPA and determine whether it can be predicted by sex, the family of the instrument practiced, acting as a soloist, or the type of training received. MATERIAL AND METHOD: The sample was composed of 72 musicians, between 16 and 54 years old (M = 24.11, SD = 9.03). They were administered the KMPAI-E to measure stage anxiety and NEO-FFI to measure personality. A bivariate correlation and a multiple regression analysis were performed. RESULTS: The results showed a positive correlation between MPA and neuroticism (p < .01) and a negative correlation with extraversion (p < .01) and responsibility (p < .05). Likewise, the instrument family and sex were determined as predictive variables of MPA. In terms of sex, there were significant differences (p < .01) in MPA, with women obtaining the highest scores. Regarding the instrument family, there was a significant difference with the plucked string (p < .05). Being a soloist and the type of training did not predict MPA. CONCLUSIONS: A personality prone to neuroticism and introversion seems to have an influence on the MPA. Likewise, the fact of being a woman and practicing plucked string instruments could predict MPA

Evaluación de la variedad y calidad en los menús escolares de Asturias. Curso 2015/2016 / Evaluation of variety and quality in the school menus of Asturias. 2015/2016

Fundamentos: Desde la primera evaluación en 2011 del "Programa de Alimentación Saludable y de Producción Ecológica en los Comedores Escolares de Asturias ", se ha venido analizando la mejora de los menús en cuanto a frecuencias en la oferta de grupos de alimentos. El objetivo de este estudio fue evaluar la calidad culinaria de los menús, de forma que complemente a dicho análisis. Métodos: Estudio descriptivo transversal con una muestra por conveniencia de los 243 centros de Educación Primaria de Asturias, es decir, 195 en el curso 2015-16. Se solicitó un menú mensual a todos los centros y en caso de no recibir respuesta se realizó una búsqueda en Internet. Se definieron unos criterios mínimos a cumplir en frecuencias, variedad y recetas diferentes para cada grupo de alimentos. Se analizaron todos los días de los menús y las diferencias entre los menús cocinados in situ vs catering, así como entre centros de titularidad pública vs privada/concertada. El análisis de datos se realizó con el programa SPSS y las diferencias entre porcentajes de cumplimiento con la prueba Chi cuadrado. Resultados: Se analizaron 195 menús (80,2%), obteniéndose altos porcentajes de cumplimiento en todos los criterios (superiores al 80%), excepto en la variedad de carbohidratos (27,7%), fruta (22,1%), carne procesada (13,9%), oferta de verdura como primer plato (6,1%) y proteína animal en el primer plato (2,6%). Conclusiones: El cumplimiento general de las recomendaciones respecto a variedad y recetas diferentes en los colegios es muy adecuado, especialmente en los de titularidad pública y de cocina propia

Background: Since the first evaluation in 2011 of the "Healthy Eating and Ecological Production Program in School Meals of Asturias ", the improvement of the menus has been analyzed in terms of frequencies in the food group offer. The objective of this study was to evaluate the culinary quality of the menus, in order to complement this analysis. Methods: Transversal descriptive study with a sample for convenience of the 243 Primary Education centers of Asturias, that is, 195 in the 2015-16 academic year.. A monthly menu was requested to all the centers and in case of not receiving a response, a search was made on the Internet. Minimum criteria were defined to comply with frequencies, variety and recipes for each food group. The menus were analyzed every day and the differences between the menus cooked on site vs catering, as well as between public versus private / concerted centers. The data analysis was performed with the SPSS program and the differences between percentages of compliance with the Chi square test. Results: 195 menus were analyzed (80.2%), obtaining high percentages of compliance in all the criteria (over 80%), except in the variety of carbohydrates (27.7%), fruit (22.1%). %), processed meat (13.9%), vegetable offer as first course (6.1%) and animal protein in the first course (2.6%). Conclusions: The general compliance of the recommendations with respect to variety and different recipes in the schools is very adequate, especially in those of public ownership and with own kitchen type

La degeneración real de la prótesis aórtica Mitroflow: análisis con riesgos competitivos / Real structural valve deterioration of the mitroflow aortic prosthesis: competing risk analysis

Introducción y objetivos: La prótesis aórtica Mitroflow es una válvula de pericardio bovino especialmente diseñada para aumentar el área valvular. Hay controversia en relación con su patrón de degeneración estructural valvular (DEV). El objetivo es conocer la incidencia acumulada de DEV, los factores que influyen en su aparición y su impacto sobre la mortalidad. Métodos: Se siguió a 1.028 pacientes clínica y ecocardiográficamente. Puesto que se trata de una población cardiópata y anciana, se realizó un análisis de riesgos competitivos. Resultados: El porcentaje de DEV a los 5 años fue 4,22% (IC95%, 2,96-5,81) y a los 8 años 15,77% (IC95%, 12,46-19,43). La incidencia fue superior para las válvulas de tamaños pequeños (19 y 21 mm). A los 5 años llegó al 6,43% (IC95%, 4,48-8,84) y a los 8 años al 20,06% (IC95%, 15,53-25,01). El desajuste paciente-prótesis (DPP) grave influyó en la incidencia de DEV (sHR = 3,53; IC95%, 2,20-5,66; p < 0,001). Sin embargo, el DPP moderado no tuvo ningún impacto. La presencia de DEV fue el mayor predictor de mortalidad (HR = 4,59; IC95%, 2,91-7,22; p < 0,001). Conclusiones: Utilizando una definición basada en el aumento del gradiente transprotésico, la incidencia de DEV de la prótesis Mitroflow es superior a la indicada por otras series, especialmente para las de tamaños pequeños (19 y 21 mm) o en pacientes con DPP grave. Aumenta exponencialmente a partir del quinto año y desde que se diagnostica aumenta por 4,5 el riesgo de muerte (AU)

Introduction and objectives: The Mitroflow aortic prosthesis is a bovine pericardial bioprosthesis specially designed to increase the valve area in relation to its size. There is controversy regarding the pattern of structural valve deterioration (SVD). Our aim was to determine the cumulative incidence of SVD, risk factors influencing its occurrence, and its impact on mortality. Methods: A total of 1028 patients were clinically and echocardiographically followed up. Because the study population was elderly and had heart disease, we used a competing risk analysis. Results: The percentage of patients with SVD at 5 years was 4.22% (95%CI, 2.96-5.81) and was 15.77% at 8 years (95%CI, 12.46-19.43). The incidence was higher for small valves (19 mm and 21 mm) reaching 6.43% at 5 years (95%CI, 4.48-8.84) and 20.06% at 8 years (95%CI, 15.53-25.01). Severe patient-prosthesis mismatch (PPM) influenced the incidence of SVD (sHR, 3.53; 95%CI, 2.20-5.66; P < .001) but moderate PPM had no impact. The most powerful predictor of mortality was the presence of SVD (HR, 4.59; 95%CI, 2.91-7.22; P < .001). Conclusions: This study used a definition based on the increase in the transprosthetic gradient and found a higher incidence of SVD of the Mitroflow prosthesis than that reported by other series, especially for sizes 19 mm and 21 mm and in patients with severe PPM. The incidence of SVD increased exponentially from the fifth year after implantation and its occurrence led to a 4.5-fold increase in the risk of death (AU)
