ABSTRACT Objectives: To assess the prevalence of peripheral artery disease in kidney transplant patients and the validity of intermittent claudication for its diagnosis. Methods: Setting and period: Nephrology Department of the University Hospital A. Coruña, 2013-2017. Inclusion criteria: transplant patients with functioning grafts who gave their consent to participate in the study. Sample size rationale: n=371 patients (confidence interval= 95%; precision= ± 4.25%). Measurements: age, age at the time of transplant, sex, dyslipemia, body mass index, smoking, diabetes, sign of Godet, perimalleolar edema, ankle-brachial index and the Edinburgh Questionnaire. Cardiovascular risk was measured with these scores: Framingham-Wilson, Regicore, SCORE and Dorica. Results: The mean age at the time of transplant was 47.86±12.62; 65.5% of patients were men and 8.7% of them had an ankle-brachial index of <0.90. When answering the Edinburgh Questionnaire, 16.2% of subjects reported suffering from intermittent claudication. Concordance between these two diagnostic tests is poor (kappa index= 0.34). The Edinburgh Questionnaire showed a sensitivity of 59.38% in predicting the ankle-brachial index (<0.90) and specificity (88.10%). The variables associated with the presence of artery disease are age at the time of transplant (OR=1.07) and smoking (OR=6.17), dyslipidemia being at the limit of statistical significance. Conclusions: A tenth part of the patients have peripheral artery disease. Concordance between the Edinburgh Questionnaire and the ankle-brachial index is poor; therefore, the latter should be used as diagnostic method. Clinical signs and symptoms underestimate the prevalence of artery disease. Age, smoking and dyslipidemia increase the risk of this disease. Artery disease patients have a higher cardiovascular risk.

RESUMEN Objetivos: Determinar en pacientes trasplantados renales la prevalencia de enfermedad arterial periférica y la validez de las manifestaciones clínicas de claudicación intermitente para su diagnóstico. Material y métodos: Ámbito y período: Servicio de Nefrología del Complejo Hospitalario Universitario A Coruña, 2013-2017. Criterios inclusión: pacientes trasplantados renales con injerto funcionante que consientan participar en el estudio. Justificación del tamaño muestral: n=371 pacientes (seguridad= 95% y precisión= ± 4,25%). Mediciones: edad, edad al trasplante, sexo, dislipemia, índice de masa corporal, tabaquismo, diabetes, signo de Godet, edema perimaleolar, índice tobillo-brazo y cuestionario Edimburgo. El riesgo cardiovascular se midió mediante los scores Framingham-Wilson, Regicor, SCORE y Dorica. Resultados: La edad media al trasplante fue de 47,86 ± 12,62 años, 65,5% hombres. El 8,7% de los pacientes presentan un índice tobillo-brazo <0,90. El 16,2% de los pacientes manifiestan claudicación intermitente según el cuestionario Edimburgo. La concordancia entre ambas pruebas diagnósticas es débil (índice de Kappa=0,34). El cuestionario de Edimburgo mostró sensibilidad del 59,38% para predecir índice tobillo-brazo <0,90 y especificidad del 88,10%. Las variables asociadas a la presencia de arteriopatía son la edad al trasplante (OR=1,07) y el tabaquismo (OR=6,17), encontrándose la dislipemia en el límite de la significación estadística. Conclusiones: Una décima parte de los pacientes presentan arteriopatía periférica. La concordancia entre el cuestionario Edimburgo y el índice tobillo-brazo es débil. Por lo que debería usarse el índice tobillo-brazo como método diagnóstico. Las manifestaciones clínicas infraestiman la prevalencia de arteriopatía. La edad, el tabaquismo y la dislipemia incrementan su riesgo. Los pacientes con arteriopatía presentan riesgo cardiovascular más elevado.

RESUMO Objetivos: determinar a qualidade de vida e a ansiedade de pacientes com câncer de mama e as mudanças sofridas após os tratamentos. Método: estudo prospectivo. Incidentes de câncer de mama (n = 339, nível de confiança = 95%, precisão = ± 5,32%). Os questionários de qualidade de vida foram o QLQC-30 e o QLQBr23 e o de ansiedade, o Inventário de Ansiedade Traço Estado (IDATE; em inglês: State-Trait Anxiety Inventory - STAI). Foi feita uma análise multivariada para identificar as variáveis associadas à qualidade de vida e à ansiedade iniciais e as diferenças entre os períodos pré e pós tratamento. Foi obtido consentimento informado e uma autorização do Comitê de Ética. Resultados: as dimensões iniciais da qualidade de vida com as menores pontuações foram: perspectivas futuras (46,0/100) e prazer sexual (55,7/100). Dimensões com as pontuações mais altas: imagem corporal (94,2/100) e funcional (93,3/100). Os sintomas mais perturbadores foram: insônia, fadiga e preocupação com a queda de cabelo. Após os tratamentos, pioraram: função física, funcional, imagem corporal, preocupações financeiras e sintomatologia. A função emocional e as perspectivas futuras melhoraram. A ansiedade grave foi apresentada como estado (48,6%) e como traço (18,2%). A maior ansiedade inicial como estado estava associada ao estado civil de casada ou viúva e ao uso de medicamentos ansiolíticos. A maior ansiedade como traço estava associada a: situação inativa no trabalho, medicamentos ansiolíticos, inchaço nas mamas e estágios avançados no momento do diagnóstico. Após os tratamentos, a ansiedade diminui significativamente. Conclusões: após os tratamentos, a pontuação da qualidade de vida é modificada positivamente e a ansiedade como estado e traço diminui.

ABSTRACT Objectives: to determine the quality of life and anxiety in patients with breast cancer and the changes they experience after treatments. Method: prospective study. Breast cancer statistics (n=339, confidence=95%, accuracy= ± 5.32%). The quality of life questionnaires (QLQ) used were QLQ C-30 and QLQ Br23, and the State-Trait Anxiety Inventory (STAI) was used for anxiety. A multivariate analysis was performed to identify variables associated with baseline quality of life and anxiety as well as pre- and post-treatment differences. Authorization was obtained from the Ethics Committee, and informed consent was provided by all patients. Results: the baseline quality of life dimensions with the lowest score were future prospects (46.0/100) and sexual enjoyment (55.7/100). The dimensions with the highest score were body image (94.2/100) and role (93.3/100). The most disturbing symptoms were insomnia, fatigue and concern about hair loss. After treatment, the dimensions of physical function, role, body image, financial concerns and symptomatology worsened, whereas emotional function and future prospects improved. Severe anxiety presented as a state (48.6%) and as a trait (18.2%). The highest baseline state anxiety was associated with married-widowed status and anxiolytic medication. The greatest trait anxiety was associated with an inactive work situation, anxiolytic medication, breast swelling and advanced stage at diagnosis. After treatment, anxiety significantly decreased. Conclusions: After treatment, the quality of life score was positively modified, while state and trait anxiety decreased.

Background and aim: Recurrence in oesophageal cancer continues to remain high after curative surgery. The aim of this study was to determine the presence of recurrence after curative surgery during follow-up, and the associated variables. Methods: A retrospective and prospective follow-up study in patients with an anatomical-pathological diagnosis of oesophageal cancer who underwent curative surgery (n = 57) in the health district of A Coruña (Spain) during the period 2003-2008. The calculation of recurrence-free survival was made using a competing risks survival analysis. Results: Out of the 57 patients included in the study, 87.7% were men with a mean age of 61.4 ± 10.3 years. The median follow-up period was 18.5 months, during which 28 recurrences were detected (50.9%). Patients with dysphagia on diagnosis of the disease, as well as patients in stages III-IV, have a higher probability of recurrence during the follow-up period. The median disease-free interval was 8.5 months. After one year of follow up, 57.1% of the recurrences were diagnosed and 82.1% after 2 years of follow-up. The median post-recurrence survival rate was 4.7 months. After adjusting for a multivariate regression model, the variable with an independent effect for predicting recurrence is the TNM classification (HR = 8.49). Conclusions: The majority of the recurrences will be developed during the 2 years after surgery, with a very poor prognosis. The predictor variable for recurrence is the TMN classification.

Introduction: Legionellosis is a multisystem bacterial disease, which causes pneumonia with high mortality in patients with comorbidity and admitted in intensive care units (ICU). Objective: Determine predictors of mortality or ICU admission. Methods: Retrospective follow-up of patients diagnosed with Legionella pneumophila pneumonia in Complexo Hospitalario Universitario de A Coruña. Period 2000-2013 (n = 240). Analysis of multivariate logistic regression was performed. Results: Mean age was 57.2 ± 15.4 years old, 88.3% were male. Average score of comorbidity (Charlson score) was 2.3 ± 2.3. There was a clear seasonal variation. Predominant symptoms were fever (92.5%), dry cough (38.1%) and dyspnea (33.9%). Creatinine clearance was lower than 60 mL/min/1.73 m² in 29.7% and sodium < 135 mEq/l in 58.3%. Admission to ICU rate was 16.3% and 10.8% needs mechanical ventilation. Inhospital mortality rate was 4.6%, rising to 23.1% in patients admitted to ICU. Variables associated to predict ICU admission were age (OR = 0.96), liver disease (OR = 7.13), dyspnea (OR = 4.33), delirium (OR = 5.86) and high levels of lactatedehydrogenase (OR = 1.002). Variables associated with inhospital mortality were Charlson index (OR = 1.70), mechanical ventilation (OR = 31.44) and high levels of lactatedehydrogenase (OR = 1.002). Discussion: Younger patients with liver disease, dyspnea and confusion are more likely to be admitted to ICU. Comorbidity, mechanical ventilation and elevated LDH levels are associated with higher mortality rate.

Introducción: La legionelosis es una enfermedad bacteriana multisistémica, causante de neumonías con mortalidad elevada en pacientes con comorbilidad e ingresos en Unidad de Cuidados Intensivos (UCI). Objetivo: Determinar factores pronósticos de mortalidad o ingreso en UCI. Material y Métodos: Estudio de seguimiento retrospectivo de pacientes diagnosticados de neumonía por Legionella pneumophila en Complexo Hospitalario Universitario de A Coruña (España). Período 2000-2013 (n = 240), con análisis de regresión logística multivariada. Resultados: La edad media fue 57,2 ± 15,4 años, 88,3% fueron hombres. La puntuación media de comorbilidad (score Charlson) fue 2,3 ± 2,3. Existe clara estacionalidad. La clínica predominante fue fiebre (92,5%), tos seca (38,1%) y disnea (33,9%). El 29,7% presentó aclaramiento de creatinina < 60 mL/min/1,73 m² y el 58,3% sodio < 135 mEq/l. Un 16,3% ingresó en UCI, precisando ventilación mecánica invasiva el 10,8%. La mortalidad global fue 4,6% y de 23,1% en ingresados en UCI. Variables asociadas para predecir ingreso en UCI fueron menor edad (OR = 0,96), hepatopatía (OR = 7,13), disnea (OR = 4,33), síndrome confusional (OR = 5,86) y lactato deshidrogenasa elevada (OR = 1,002). Las variables asociadas a mortalidad intrahospitalaria fueron índice de Charlson (OR = 1,70), ventilación mecánica invasiva (OR = 31,44) y cifras elevadas de lactato deshidrogenasa (OR = 1,002). Discusión: Pacientes jóvenes, con hepatopatía, disnea o confusión tienen más probabilidad de ingresar en UCI. Comorbilidad, ventilación mecánica y lactato deshidrogenasa elevada se asocian a mortalidad.

Objective: To determine the frequency and factors associated with medicine consumption and consultations with family physicians due to musculoskeletal pain in fishery workers. Methods: We performed a cross-sectional study (n = 929). The variables analyzed consisted of sociodemographic factors, the frequency of musculoskeletal pain, healthcare resource consumption, back pain disability (Roland-Morris) and health-related quality of life (SF-36). Results: A total of 98.7% of the sample were women, with a mean age of 50.6 years. Musculoskeletal pain was reported by 66.5%, 43% were taking medication, and 64% had consulted their family physician due to musculoskeletal pain. The factors associated with medication intake in the logistic regression analysis were the number of years worked in the sector, hip-knee pain, bodily pain and physical functioning. The variables associated with physician visits were the presence of hip-knee pain, neck-back-shoulder pain, bodily pain, and social functioning. Conclusions: The variables most closely associated with resource utilization were hip-knee pain and the physical dimension of health-related quality of life, especially bodily pain.

Objective: To determine health-related quality of life (HRQoL) measured with the 36-item Short-Form (SF-36) questionnaire in women workers in the fishing industry, compared with norm-based values in the reference population and other similar samples of persons with musculoskeletal disorders. Method: A cross-sectional study was performed to measure HRQoL in 917 shellfish gatherers. Women taking part in a physiotherapy workshop were invited to participate. We used a self-administered questionnaire, including questions on sociodemographic variables, lifestyle, comorbidity, the prevalence of musculoskeletal disorders, and HRQoL. For the SF-36 raw scores, norm-based scores and z-scores were calculated. Results: The mean age of participants was 50.6 years (standard deviation: 8.8). In all dimensions of the SF-36, values in the sample were lower than in the general reference population. The greatest differences were in younger people. The most affected dimensions were bodily pain, vitality and general health. Physical health was more affected than mental health. Conclusions: HRQoL, especially physical components, was worse in women shellfish gatherers than in the general population and other population samples.

Objetivo: Determinar la calidad de vida relacionada con la salud (CVRS) mediante el cuestionario SF-36 en trabajadoras del sector pesquero, y compararla con valores normalizados de población de referencia y con valores de otras muestras similares que presentan trastornos musculoesqueléticos. Método: Mediante un estudio transversal se midió la CVRS en 917 mariscadoras a pie seleccionadas a partir de la participación voluntaria en un taller de fisioterapia. Se utilizó un cuestionario autoadministrado que incluía variables sociodemográficas, de estilo de vida, de comorbilidad, de prevalencia de dolor musculoesquelético y de CVRS. Para el SF-36 se calcularon puntuaciones crudas, puntuaciones estandarizadas y puntuaciones z. Resultados: La edad media de las participantes es de 50,6 años (desviación estándar: 8,8). En todas las dimensiones del SF-36 la muestra tuvo valores inferiores que la población general de referencia. Las mayores diferencias se observaron en las personas más jóvenes. Las dimensiones más afectadas, superando la diferencia mínimamente importante, fueron dolor corporal, vitalidad y salud general. Su salud física está más afectada que su salud mental. Conclusiones: Se demuestra que este grupo de trabajadoras tiene peor CVRS que la población general y que otras muestras poblacionales, sobre todo en los componentes físicos.

Purpose: To determine if a delay between prostate biopsy (PB) and radical prostatectomy (RP) has an impact on pathological findings and prognosis of prostate cancer patients (PCa). Material and methods: Patients (n = 232) who underwent RP, with at least two postoperative PSA readings. Design: retrospective observational cohort study. Period: May 2000 - March 2007. Delay was defined as time in months between PB and RP. Statistical analysis: delay was analysed as a continuous variable or else categorised according to the median (6 months). A multivariate logistic regression analysis was performed to define variables associated with extracapsular disease. Biochemical recurrence-free survival (BRFS) was studied using the Kaplan-Meier method and multivariate Cox proportional hazards analysis. Results: Differences between delay groups < and > 6 months were significant only with regards to age (p = 0.041), considering both groups as comparable. Differences between groups related to pathological variables were not observed in any case. Mean follow-up was not significantly different between both groups (p = 0.112). The probability of extracapsular disease varied significantly depending on PSA, biopsy Gleason score and the percentage of positive cores, while multivariate analysis found no relationship with delay. Biochemical relapse was detected in 39 cases (16.81%). BRFS in delay < 6 months group was 86.1%, 78.4%, 78.4% and 78.4% at 1, 2, 5 and 7 years, while BRFS in delay > 6 months group was 88.9%, 82.8%, 77.4%, 77.4% and 77.4% at 1, 2, 5 and 7 years (p = 0.632). Delay was not associated with BRFS in multivariate analysis; only the percentage of positive cores independently predicted BRFS. In patients with high-grade PCa, percentage of positive cores was the only independent variable to predict extracapsular disease and BRFS. Delay was not associated with extracapsular disease or BRFS. Conclusions: Reasonable surgical delay does not cause a significant negative impact on pathological findings of RP specimens, nor in the BRFS of patients with localized PCa.

Objetivo: Determinar si la demora entre la biopsia de próstata y la prostatectomía radical (PR) influye en los hallazgos patológicos y en el pronóstico de los pacientes con cáncer de próstata. Material y métodos: Pacientes (n = 232) sometidos a PR, con al menos dos determinaciones postoperatorias de PSA. Diseño: estudio observacional de cohorte retrospectivo. Período: 2000-2007. Análisis estadístico: se analizó la demora como variable continua, o bien categorizándola en función de la mediana (6 meses). Análisis de regresión logística multivariable para definir variables en relación con enfermedad extracapsular. Estudio de supervivencia libre de recidiva bioquímica (SLRB) con metodología Kaplan-Meier y análisis multivariable de regresión de Cox. Resultados: Las diferencias entre los grupos de demora menor o mayor de 6 meses sólo fueron significativas respecto a la edad (p = 0,041); se consideró que ambos grupos eran comparables. El seguimiento medio no fue significativamente diferente entre ambos grupos (p = 0,112). La probabilidad de enfermedad extracapsular se modificó significativamente según PSA, índice de Gleason de la biopsia y el porcentaje de cilindros positivos, sin relación con la demora en el análisis multivariable. Se detectó recidiva bioquímica en 39 (16,81%) casos. La SLRB en el grupo de demora < 6 meses fue del 86,1, el 78,4, el 78,4 y el 78,4%, al cabo de 1, 2, 5 y 7 años, mientras que en el grupo con demora > 6 meses, la SLRB fue del 88,9, el 82,8, el 77,4 y el 77,4%, al cabo de 1, 2, 5 y 7 años (p = 0,632). En el análisis multivariable la demora no se asoció a SLRB, sólo el porcentaje de cilindros positivos predecía de forma independiente la SLRB. En pacientes con cáncer de próstata de alto grado, el porcentaje de cilindros positivos fue la única variable independiente en la predicción de enfermedad extracapsular y SLRB. La demora no se asoció con enfermedad extracapsular ni con SLRB en este grupo de pacientes. Conclusiones: La demora quirúrgica razonable no produce un impacto negativo significativo en los hallazgos patológicos de la pieza de PR ni en la SLRB de los pacientes con cáncer de próstata localizado.

Purpose: To determine prognostic factors of bladder recurrence in patients with upper urinary tract (UUT) urothelial carcinoma, who underwent nephroureterectomy. Material and methods: Patients (N=51) with UUT transitional cell carcinoma who underwent nephroureterectomy. A Retrospective and prospective observational cohort study was made during the period 1995-2007, at Arquitecto Marcide Hospital, Ferrol Health Area, La Coruña. Differences between groups with and without recurrence were analized by means of chi-squared test in qualitative variables and t-Student and U Mann-Whitney test in quantitative variables. Kaplan-Meier methodology was used in order to predict bladder recurrence free survival (BRFS), developing a multivariate Cox regression model to identify variables related to bladder recurrence. Results: Mean age of patients was 68.51±12.11 (24-86). Histological grade distribution was as follows: 7 G1 (13.72%), 20 G2 (39.21%), 23 G3 (45.10%) and 1 undetermined case(1.97%). With regard to pT category, 19 cases were pT1(37.25%), 12 pT2 (23.53%), 19 pT3 (37.25%) y 1 case undetermined (1.97%). Bladder recurrence was detected in 16 patients during follow-up (31.37%). 70.59% of recurrences were identified during first two years of follow-up. Differences related to follow-up period, presence of obstructive uropathy, microscopic growth pattern and tumour multifocality, were observed between patients without and with bladder recurrence. BRFS rates at 1, 2, 5 and 10 years were 85.10%, 67.90%, 56.60% y 31.80%, respectively. BRFS was significantly modified by tumour location (p=0.019) and tumour multifocality (p=0.002). Multivariate analysis showed that tumour multifocality was an independent factor in the prediction of bladder recurrence (RR=7.35;95%CI=1.57-34.45;p=0.011). Conclusions: The development of bladder recurrence after nephroureterectomy was observed in 31.37% of patients in our study, detecting most of events during the first two years of follow-up. Tumour multifocality in UUT constitutes the most important risk factor for the development of bladder recurrence.

Objetivo: Determinar factores pronósticos de recidiva vesical en pacientes con carcinoma urotelial del tracto urinario superior (TUS), tratados mediante nefroureterectomía. Material y métodos: Pacientes (N=51) con carcinoma de células transicionales del TUS tratados mediante nefroureterectomía. Se realizó un estudio observacional de cohorte retrospectivo y prospectivo durante el periodo 1995-2007, en el Hospital Arquitecto Marcide, Área Sanitaria de Ferrol, La Coruña. Se analizaron las diferencias entre grupos con y sin recidiva vesical mediante test chi-cuadrado en variables cualitativas y test t-Student y U Mann-Whitney en variables cuantitativas. Se estudió la supervivencia libre de recidiva vesical (SLRV) mediante la metodología de Kaplan-Meier, desarrollando un modelo multivariado de regresión de Cox para identificar variables asociadas a recidiva vesical. Resultados: La media de edad fue 68,51±12,11 años (24-86). La distribución por grado histológico fue la siguiente: 7 G1 (13,72%), 20 G2 (39,21%), 23 G3 (45,10%) y 1 caso indeterminado (1,97%). En cuanto a la categoría pT, 19 casos eran pT1 (37,25%), 12 pT2 (23,53%), 19 pT3 (37,25%) y 1 caso indeterminado (1,97%). Durante el seguimiento se detectó recidiva vesical en 16 pacientes (31,37%). El 70,59% de las recidivas se identificaron durante los dos primeros años de seguimiento. Entre los pacientes sin y con recidiva vesical se detectaron diferencias relacionadas con tiempo de seguimiento, existencia de uropatía obstructiva, morfología microscópica y multifocalidad tumoral. La SLRV al cabo de 1, 2, 5 y 10 años fue del 85,10%, 67,90%, 56,60% y 31,80%, respectivamente. La SLRV se modificó significativamente en función de la localización (p=0,019) y la multifocalidad (p=0,002) tumorales. En el análisis multivariado se observó que la multifocalidad tumoral predecía de forma independiente la recidiva vesical (RR=7,35;95%IC=1,57-34,45;p=0,011). Conclusiones: El desarrollo de recidiva vesical tras nefroureterectomía se observa en el 31,37% del los pacientes de nuestro estudio, detectándose la mayoría de los episodios durante los dos primeros años de seguimiento. La multifocalidad tumoral en el TUS es el factor de riesgo más importante para el desarrollo de recidiva vesical.
