Efecto de la espirometría incentiva y máscara PEP en la función pulmonar de mujeres tratadas de cáncer de mama con radioterapia: estudio de caso / Effect of incentive spirometry and PEP mask on lung function in women treated for breast cancer with radiotherapy: Case study

Antecedentes y objetivos: La toxicidad pulmonar inducida por radiación es un proceso común, pero poco atendido, ocasionado tras la aplicación de radioterapia en el cáncer de mama. A largo plazo tras la aplicación de radioterapia se ha encontrado una disminución de los test pulmonares y de la difusión de oxígeno, pudiendo provocar fatiga e intolerancia al ejercicio en las mujeres supervivientes al carcinoma mamario. El objetivo de este trabajo fue mejorar la función pulmonar a través de un programa de trabajo con espirometría incentiva y máscara de presión espiratoria positiva en las mujeres tratadas de cáncer de mama con radioterapia, y describir su efecto sobre la tolerancia al esfuerzo y la percepción de fatiga. Descripción de los casos: Cinco mujeres que percibieron fatiga tras la aplicación de radioterapia. Intervención: Se llevó a cabo un tratamiento domiciliario basado en la utilización de la espirometría incentiva y de la máscara de presión espiratoria positiva, trabajando diariamente 30min, a lo largo de 3 semanas. Resultados y discusión: El tratamiento con espirometría incentiva y máscara presión espiratoria positiva parece mejorar las secuelas pulmonares inducidas por radioterapia y aumentar la tolerancia al esfuerzo en mujeres tratadas de cáncer de mama. Sin embargo, la variabilidad en los resultados obtenidos hace que no puedan ser concluyentes

Background and objective: Radiation-induced pulmonary toxicity is a common process following radiation therapy in breast cancer which is not usually considered. In the long term after the application of radiotherapy, a decrease in pulmonary tests and in carbon monoxide diffusing capacity has been found. It may lead to fatigue and intolerance to exercise in women surviving mammary carcinoma. The objective of this paper was to improve pulmonary function through a work programme with EI and mask of PEP in women treated for breast cancer with radiotherapy and describe if it has a beneficial effect on the tolerance to effort and the perception of fatigue. Cases description: Five women who perceived fatigue after the application of radiotherapy. Intervention: A domiciliary treatment was carried out based on the use of the EI and the PEP mask, working daily for 30minutes over 3 weeks. Result and discussion: Treatment with IE and the PEP mask seems to improve the pulmonary effects induced by radiotherapy and increases exercise tolerance in women treated for breast cancer. However, the variability in the results obtained means that they cannot be conclusive

Importancia de la electrofisiología ocular en el diagnóstico de las distrofias retinianas / Importance of ocular electrophysiology in the diagnosis of retinal dystrophies

Antecedentes y objetivo: El diagnóstico de las distrofias retinianas es complejo y se basa en estudio oftalmológico completo, estudio genético y los estudios electrofisiológicos (EEF). En este estudio pretendemos evaluar el papel de las pruebas electrofisiológicas y del médico solicitante en el diagnóstico de las distrofias de retina. Materiales y métodos: Estudio observacional retrospectivo. Se seleccionaron 50 pacientes atendidos en el Servicio de Neurofisiología del Hospital Universitario Virgen Macarena. Se valoró el sexo, la edad, el hospital de origen, motivo por el que se solicitó los EEF, diagnóstico de presunción tras examen oftalmológico, EEF realizados, estudio genético y el diagnóstico definitivo tras realización de EEF. Se elaboró un sistema de clasificación que otorga a cada caso un valor comprendido entre 0 y 2, en función de la contribución de las pruebas electrofisiológicas al diagnóstico final. Resultados: La edad media fue 44,34 ± 18,03 años (60% mujeres). Retinosis pigmentaria, neuropatía óptica y enfermedad de Stargardt fueron los diagnósticos más frecuentes. Los EEF modificaron el diagnóstico de presunción en el 48% de los casos, confirmaron el diagnóstico en el 44% y no aportaron información en el 8%. La contribución de los EEF fue mayor en pacientes atendidos en el Hospital Universitario Virgen Macarena y cuando se solicitaban por hallazgos en la exploración (p = 0,001). Los falsos positivos para distrofia retiniana fueron del 60% en pacientes no valorados en dicho hospital. Conclusiones: Las pruebas electrofisiológicas y el manejo especializado de los pacientes con distrofias retinianas desempeñan un papel importante en el diagnóstico de estas patologías

Background and objective; The diagnosis of retinal dystrophies is complex and is based on complete ophthalmological study, genetic study and electrophysiological studies (EPS). In this study, we intend to evaluate the role of electrophysiological and medical tests in the diagnosis of retinal dystrophies. Material and methods: A retrospective observational study was conducted on 50 selected patients that attended the Neurophysiology Department of the University Hospital Virgen Macarena. An analysis was made of the variables that included, gender, age, referral hospital, reason for which the EPS was requested, applied EPS, genetic study, presumed diagnosis, and definitive diagnosis after EPS. A classification system was subsequently developed, which gives each case a value between 0 and 2, depending on the contribution of the electrophysiological tests to the final diagnosis. Results: The mean age was 44.34 ± 18.03 years (60% women). Retinitis pigmentosa (24%), optic neuropathy (12%), and Stargardt's disease (8%) were the most frequent diagnoses. The EPS modified the presumed diagnosis in 48% of the cases, confirmed the diagnosis in 44%, and did not provide any useful information in 8%. The contribution of the EPS was greater in patients seen in the HUVM and when requested by findings in the examination (P = .001). The false positives in the diagnosis of retinal dystrophy were 60% in patients not evaluated by the University Hospital Virgen Macarena. Conclusions: Electrophysiological test and specialised management of patients with retinal dystrophies play an important role in the diagnosis of these conditions

Patient, tumor, and healthcare factors associated with regional variability in lung cancer survival: a Spanish high-resolution population-based study.

PURPOSE: The third most frequently diagnosed cancer in Europe in 2018 was lung cancer; it is also the leading cause of cancer death in Europe. We studied patient and tumor characteristics, and patterns of healthcare provision explaining regional variability in lung cancer survival in southern Spain. METHODS: A population-based cohort study included all 1196 incident first invasive primary lung cancer (C33-C34 according to ICD-10) cases diagnosed between 2010 and 2011 with follow-up until April 2015. Data were drawn from local population-based cancer registries and patients' hospital medical records from all public and private hospitals from two regions in southern Spain. RESULTS: There was evidence of regional differences in lung cancer late diagnosis (58% stage IV in Granada vs. 65% in Huelva, p value < 0.001). Among patients with stage I, only 67% received surgery compared with 0.6% of patients with stage IV. Patients treated with a combination of radiotherapy, chemotherapy, and surgery had a 2-year mortality risk reduction of 94% compared with patients who did not receive any treatment (excess mortality risk 0.06; 95% CI 0.02-0.16). Geographical differences in survival were observed between the two regions: 35% vs. 26% at 1-year since diagnosis. CONCLUSIONS: The observed geographic differences in survival between regions are due in part to the late cancer diagnosis which determines the use of less effective therapeutic options. Results from our study justify the need for promoting lung cancer early detection strategies and the harmonization of the best practice in lung cancer management and treatment.

Childhood and adolescent lymphoma in Spain: incidence and survival trends over 20 years

Background: Lymphoma is the third most common malignancy in children (0-14 years) and the first in adolescents (15-19 years). This population-based study-the largest ever done in Spain-analyses incidence and survival of lymphomas among Spanish children and adolescents. Patients and methods 1664 lymphoma cases (1983-2007) for incidence and 1030 for survival (1991-2005) followed until 31/12/2010, were provided by 11 cancer registries. Age-adjusted incidence rates (ASRw) to the world standard population were obtained; incidence trends were modelled using the Joinpoint programme, observed survival (OS) was estimated with Kaplan-Meier and trends tested with a log-rank test. Results are presented according to the International Classification of Childhood Cancer-3. Results: In Spain, the ASRw0-14 for lymphomas was 17.5 per 1.000.000 child-years and 50.0 the specific rate for adolescents. Overall incidence increased significantly during 1983-1997 with no increases thereafter. Patients over 9 years old showed significant rising trends for all subtypes, except for Burkitt lymphoma (BL) in adolescents. During 2001-2005 (age 0-19 years), 5-year OS was 94 (90-98), 73 (64-83) and 86 (78-94) for Hodgkin lymphoma (HL), non-Hodgkin lymphoma (NHL) and BL, respectively. No improvement in survival was found. The incidence in Spain was higher than overall European rates, but within the range of that in Southern Europe. Comparing OS in Spain 1991-1995 and 2001-2005 with results for Europe of the Automated Childhood Cancer Information System (ACCIS) (1988-1997) and the European cancer registry-based study on survival and care of cancer patients (EUROCARE) (2000-2007), it was similar for HL and lower for NHL and BL. Conclusions: Systematic monitoring and analysis of lymphoma paediatric data would provide clinical and epidemiological information to improve the health care of these patients and the outcomes for these malignancies in Spain

El vendaje cohesivo en el tratamiento de la trombosis linfática superficial en mujeres intervenidas de cáncer de mama. Serie de casos / The cohesive bandage in the treatment of axillary web syndrome in women after breast cancer surgery. Case series

Antecedentes y objetivos: Las trombosis linfáticas superficiales (TLS) son una complicación postquirúrgica del cáncer de mama bastante habitual. Consiste en la inflamación de los vasos linfáticos debido a la formación de un trombo en su extremo proximal, tras extirpación de nódulos axilares. El objetivo de este trabajo es comprobar si el vendaje cohesivo reduce el tiempo de resolución de las TLS en menos de 3 semanas. Descripción de los casos: Ocho mujeres que desarrollaron TLS tras la extirpación de ganglios linfáticos axilares. Intervención: Se llevó a cabo un tratamiento basado en vendaje cohesivo, puesta en tensión de los vasos linfáticos, cinesiterapia activa, crema antiinflamatoria y educación terapéutica. Resultados y discusión: El uso del vendaje cohesivo parece reducir el tiempo de resolución de la TLS en menos de 3 semanas

Background and objectives: Axillary web syndrome (AWS) is a fairly common post-surgical complication of breast cancer. It consists of the inflammation of lymphatic vessels, due to the formation of a thrombus at its proximal end, and as a result of removal of axillary nodes.The objective of this study is to determine if the use of cohesive bandage reduces the resolution time of AWS in less than 3 weeks. Cases description: Eight women who developed AWS after axillary lymph node dissection. Intervention: A treatment based on cohesive bandage, stretching of the lymphatic vessels; active upper limb exercises; anti-inflammatory cream; and therapeutic education. Results and discussion: The use of cohesive bandage seems to reduce the resolution time of AWS in less than 3 weeks

Night-shift work and breast and prostate cancer risk: updating the evidence from epidemiological studies / Trabajo nocturno por turnos y el riesgo de cáncer de mama y próstata: actualizando la evidencia a partir de estudios epidemiológicos

It has been hypothesized that circadian disruption is related to higher cancer risk. Since the International Agency for Research on Cancer classified shift work involving circadian disruption as probably carcinogenic to humans (Group 2A), multiple studies have been conducted to test this hypothesis. The aim of this systematic review was to summarize the findings and evaluate the quality of existing epidemiological studies (case-control and cohort studies) on the relationship between night-shift work and breast and prostate cancer risk. Thirty-three epidemiological studies investigating the relationship between night-shift work and breast (n = 26) or prostate (n = 8) cancer risk were included (one paper included both sites). The Newcastle-Ottawa Scale for the quality of non-randomized studies was used to assess the risk of bias of the publications. The studies included were heterogeneous regarding population (general population, nurses working in rotating shifts, and other) and measurement of exposure to night-shift work (ever vs. never exposure, short vs. long-term, rotating vs. permanent) and, thus, a diversity of outcomes were observed even within the same type of cancer. In summary, 62.5% works found some type of association between night-shift work and increased risk of cancer, for both breast and prostate. The risk of bias scored an average of 7.5 over 9 stars. Due to the limitations inherent in these studies, the evidence of a possible association between night-shift work and breast or prostate cancer risk remains uncertain and more studies providing greater control of exposure and confounding factors are required. Despite the lack of conclusive evidence, application of the precautionary principle seems advisable

Se ha formulado la hipótesis de que la disrupción circadiana está relacionada con un mayor riesgo de cáncer. Desde que la Agencia Internacional de Investigación sobre el Cáncer clasificó la disrupción circadiana asociada al trabajo por turnos como "probablemente carcinógeno para los humanos" (Grupo 2A) se han llevado a cabo numerosos estudios para confirmar o rechazar esta hipótesis. Por esa razón, el objetivo de esta revisión sistemática fue analizar la posible asociación entre el trabajo nocturno por turnos y el riesgo de cáncer de mama o próstata. Se incluyeron treinta y tres estudios epidemiológicos sobre la relación entre el riesgo de padecer cáncer de mama (n = 26) o próstata (n = 8) y el trabajo nocturno; un estudio evaluó ambas localizaciones. El riesgo de sesgo de los artículos se evaluó mediante la escala Newcastle-Ottawa. Los estudios incluidos en esta revisión fueron heterogéneos respecto a población incluida (población general, enfermeras a turnos, y otros), medida de la exposición a trabajo nocturno (siempre vs nunca, a corto vs largo plazo, a turnos o fijo) y, por tanto, los hallazgos fueron variados incluso para el mismo tipo de cáncer. En resumen, un 62,5% de los estudios encontraron asociación entre el trabajo nocturno y el riesgo aumentado de padecer cáncer, tanto de mama como de próstata. El riesgo de sesgo medio fue de 7,5 estrellas sobre 9. Debido a las limitaciones inherentes a estos estudios, la evidencia de una posible asociación entre el trabajo nocturno y el riesgo de cáncer de mama o próstata sigue siendo incierta, por lo que se requieren más estudios epidemiológicos con mayor control de la exposición y de los factores de confusión. No obstante, parece aconsejable la aplicación del principio de precaución

Efecto del tratamiento de radioterapia en el hombro homolateral en mujeres intervenidas de cáncer de mama / Effect of radiotherapy treatment in the homolateral shoulder in breast-cancer patients

Objetivo: Conocer los efectos secundarios en el miembro superior tras el tratamiento de radioterapia en mujeres intervenidas por cáncer de mama e identificar si existen diferencias en función del servicio de radioterapia que las atiende. Sujetos, material y métodos: Estudio longitudinal prospectivo, en el que participaron 22 mujeres que iban a recibir tratamiento de radioterapia en los hospitales Gregorio Marañón y Ramón y Cajal de Madrid. Se realizó una valoración previa al tratamiento de radioterapia y otra inmediatamente después. En las exploraciones se recogió el rango de movimiento del hombro, el dolor, el grado de disfunción del miembro superior y el grado de radiodermatitis. Resultados: Todas las participantes mostraron una limitación en los movimientos del hombro homolateral a la cirugía antes de comenzar la radioterapia. Tras el tratamiento de radioterapia el rango de movimiento del hombro se vio reducido en los movimientos de rotación interna y rotación externa, además de aumentar de manera estadísticamente significativa el dolor y la discapacidad del miembro superior (p < 0,05). Las mujeres atendidas en el Hospital Ramón y Cajal vieron más reducido el movimiento de rotación externa, mientras que la lesión cutánea fue mayor en las mujeres tratadas en el Hospital Gregorio Marañón. Conclusiones: El tratamiento de radioterapia produce a corto plazo toxicidad cutánea, un aumento del dolor y la discapacidad en el miembro superior y contribuye a limitar el rango de movimiento del hombro en los movimientos de rotación interna y rotación externa. Estos resultados parecen variar en función del servicio de radioterapia que atiende a las mujeres

Objective: To identify the secondary effects in the upper limb after radiotherapy treatment in women diagnosed with breast cancer, as well as to determine if there are differences in the outcomes depending on the radiotherapy service that treated the participants. Participants, material, and methods: A longitudinal prospective study was performed on 22 women who received radiotherapy treatment in the Gregorio Marañón and Ramón y Cajal Hospitals in Madrid. The assessments were carried out before and after the radiotherapy treatment. The outcomes recorded were shoulder range of motion, pain, upper limb disability and the level of radiodermatitis. Results: All the participants showed a restriction in the shoulder movement after the surgery, and before the radiotherapy. After the radiotherapy treatment, there was a decrease in the internus and externus rotation movements of the shoulder. Furthermore, there was a statistically significant increase in pain and upper limb dysfunction. Women treated in the Ramón y Cajal Hospital showed a decrease in externus rotation movement, whereas women treated in the Gregorio Marañón Hospital suffered from greater skin toxicity. Conclusions: Radiotherapy treatment increases pain and upper limb disability, produces skin toxicity, and decreases the rotation mobility of the shoulder in the short-term. The secondary effects may vary according to hospital protocols

Cancer survival in adult patients in Spain. Results from nine population-based cancer registries

Introduction. With the aim of providing cancer control indicators, this work presents cancer survival in adult (≥15 years) patients in Spain diagnosed during the period 2000-2007 from Spanish cancer registries participating in the EUROCARE project. Methods. Cancer cases from nine Spanish population-based cancer registries were included and analysed as a whole. All primary malignant neoplasms diagnosed in adult patients were eligible for the analysis. Cancer patients were followed until 31 December 2008. For each type of cancer, 1-, 3- and 5-year observed and relative survival were estimated by sex, age and years from diagnosis. Furthermore, age-standardized 5-year relative survival for the period 2000-2007 has been compared with that of the period 1995-1999. Results. Skin melanoma (84.6 95% CI 83.0-86.2), prostate (84.6% 95% CI 83.6-85.6) and thyroid (84.2% CI 95% 82.0-86.6) cancers showed the highest 5-year relative survival, whereas the worst prognosis was observed in pancreatic (6% 95% CI 5.1-7.0) and oesophageal (9.4% 95% CI 7.9-11.1) cancers. Overall, survival is higher in women (58.0%) than in men (48.9%). The absolute difference in relative survival between 2000-2007 and 1995-1999 was positive for all cancers as a whole (+4.8% in men, +1.6% in women) and for most types of tumours. Survival increased significantly for chronic myeloid leukaemia, non-Hodgkin’s lymphoma and rectum cancer in both sexes, and for acute lymphoid leukaemia, prostate, liver and colon cancers in men and Hodgkin’s lymphoma and breast cancer in women. Survival patterns by age were similar in Europe and Spain. A decline in survival by age was observed in all tumours, being more pronounced for ovarian, corpus uteri, prostate and urinary bladder and less for head and neck and rectum cancers. Conclusion. High variability and differences have been observed in survival among adults in Spain according to the type of cancer diagnosed, from above 84% to below 10%, reflecting high heterogeneity. The differences in prognosis by age, sex and period of diagnosis reveal opportunities for improving cancer care in Spain (AU)

Geographical variability in survival of European children with central nervous system tumours.

Survival for childhood central nervous system (CNS) tumours varies across Europe, partly because of the difficulty of distinguishing malignant from non-malignant disease. This study examines bias in CNS tumours survival analysis to obtain the reliable and comparable survival figures. We analysed survival data for about 15,000 children (age <15) diagnosed with CNS between 2000 and 2007, from 71 population-based cancer registries in 27 countries. We selected high-quality data based on registry-specific data quality indicators and recorded observed 1-year and 5-year survival by countries and CNS entity. We provided age-adjusted survival and used a Cox model to calculate the hazard ratios (HRs) of death, adjusting by age, site and grading by country. Recording of non-malignant lesions, use of appropriate morphology codes and completeness of life status follow-up differed among registries. Five-year survival by countries varied less when non-malignant tumours were included, with rates between 79.5% and 42.8%. The HRs of dying, for registries with good data, adjusting by age and grading, were between 0.7 and 1.2; differences were similar when site (supra- and infra-tentorial) was included. Several sources of bias affect the correct definition of CNS tumours, the completeness of incidence series and the goodness of follow-up. The European Network of Cancer Registries needs to improve childhood cancer registration and stress the need to update the International Classification for Cancer. Since survival differences persisted even when restricting the analysis to registries with satisfactory data, and since diagnosis of CNS tumours is difficult and treatment complex, national plans must aim for the revision of the diagnosis and the coordination of care, with adequate national and international networks.

Cancer incidence in Spain, 2015

Purpose. Periodic cancer incidence estimates of Spain from all existing population-based cancer registries at any given time are required. The objective of this study was to present the current situation of cancer incidence in Spain. Methods. The Spanish Network of Cancer Registries (REDECAN) estimated the numbers of new cancer cases occurred in Spain in 2015 by applying the incidence-mortality ratios method. In the calculus, incidence data from population-based cancer registries and mortality data of all Spain were used. Results. In 2015, nearly a quarter of a million new invasive cancer cases were diagnosed in Spain, almost 149,000 in men (60.0%) and 99,000 in women. Globally, the five most common cancers were those of colon-rectum, prostate, lung, breast and urinary bladder. By gender, the four most common cancers in men were those of prostate (22.4%), colon-rectum (16.6%), lung (15.1%) and urinary bladder (11.7%). In women, the most common ones were those of breast (28.0%), colon-rectum (16.9%), corpus uteri (6.2%) and lung (6.0%). In recent years, cancer incidence in men seems to have stabilized due to the fact that the decrease in tobacco-related cancers compensates for the increase in other types of cancer like those of colon and prostate. In women, despite the stabilization of breast cancer incidence, increased incidence is due, above all, to the rise of colorectal and tobacco-related cancers. Conclusion. To reduce these incident cancer cases, improvement of smoking control policies and extension of colorectal cancer screening should be the two priorities in cancer prevention for the next years (AU)

Efecto del tratamiento fisioterapéutico en mujeres con trombosis linfática superficial tras cirugía de cáncer de mama: serie de casos / Effect of physiotherapy treament in women with axillary web syndrome after breast cancer surgery: Case series

Antecedentes y objetivo: La trombosis linfática superficial (TLS) es una complicación bastante habitual tras cirugía de cáncer de mama. Consiste en la formación de un trombo en el extremo de los vasos linfáticos, debido a la rotura de estos por extirpación de nódulos axilares y su posterior inflamación. Su resolución espontánea se da en 12-15 semanas. El objetivo de este trabajo es aportar datos sobre el efecto del tratamiento fisioterapéutico en TLS tras cirugía de cáncer de mama. Descripción de los casos: Tres mujeres que desarrollaron TLS después de extirpación de ganglios linfáticos axilares. Intervención: Se llevó a cabo un tratamiento basado en drenaje linfático manual, ejercicios de estiramiento del cordón y aplicación de crema antiinflamatoria. Se complementó con educación terapéutica. Resultado y discusión: La aplicación de tratamiento de fisioterapia en mujeres con TLS podría reducir el tiempo de resolución a 3-4 semanas, mejorando la sintomatología

Background and objective: axillary web syndrome (AWS) is a fairly common complication that appears after breast cancer surgery. It consists on a thrombus formation at the end of the lymphatics due to their breakage by removal of axillary nodes, and their subsequent inflammation. Spontaneous resolution is between 12 and 15 weeks. The objective of this study is to provide data about the effect of physiotherapy treatment in AWS after breast cancer surgery. Cases description: three women who developed TLS after axillary lymph node dissection. Intervention: a treatment based on manual lymph drainage, stretching exercises of the lymphatic cord and implementation of anti-inflammatory cream was applied. This was supplemented with therapeutic education. Result and discussion: application of physiotherapy treatment in women with AWS could reduce resolution time to 3-4 weeks improving their symptoms

Incidence and survival time trends for Spanish children and adolescents with leukaemia from 1983 to 2007

Objective. We have analysed incidence and survival trends of children and adolescents with leukaemia registered in Spanish population-based cancer registries during the period 1983-2007. Methods. Childhood and adolescent leukaemia cases were drawn from the 11 Spanish population-based cancer registries. For survival, registries with data for the period 1991-2005 and follow-up until 31-12-2010 were included. Overall incidence trends were evaluated using joinpoint analysis. Observed survival rates were estimated using Kaplan-Meier, and trends were tested using the log-rank test. Results. Based on 2606 cases (2274 children and 332 adolescents), the overall age-adjusted incidence rate (ASRw) of leukaemia was 47.9 cases per million child-years in children and 23.8 in adolescents. The ASRw of leukaemia increased with an annual percentage change of 9.6 % (95 % CI: 2.2-17.6) until 1990 followed by a stabilisation of rates. In adolescents, incidence did not increase. Five-year survival increased from 66 % in 1991-1995 to 76 % in 2001-2005. By age, survival was dramatically lower in infants (0) and adolescents (15−19) than in the other age groups and no improvement was observed. In both children and adolescents, differences in 5-year survival rates among major subgroups of leukaemias were significant. Conclusions. The increasing incidence trends observed in childhood leukaemias during the study period were confined to the beginning of the period. Remarkable improvements in survival have been observed in Spanish children with leukaemias. However, this improvement was not observed in infants and adolescents (AU)

Trends in lung cancer incidence by histologic subtype in the south of Spain, 1985-2012: a population-based study

Purpose: To analyze and interpret age- and sex-specific incidence trends of lung cancer in Granada over the period 1985–2012 and to further analyze these trends by histologic subtype. Methods: Incidence data were obtained from the population-based cancer registry located in Granada (Southern Spain). All cases with newly diagnosed primary lung cancer over the period 1985–2012 (n = 8658) and defined by International Classification of Diseases 10th Revision (codes C33–C34) were included. Joinpoint regression analysis of age-standardized incidence rates was used to estimate the annual percent change (APC) and 95 % confidence intervals. Results are presented overall and by sex, age groups (0-34, 35-54, 55-64, 65-74, C75 years) and histologic subtypes. Results: Temporal trends of incidence rates by sex, over the period 1985–2012, showed a distinct pattern. A significant change point of the trend was observed in males in 1994 (APC: ?2.5 %; 95 % CI 0.7-4.4 from 1985 to 1994 and -1.4 %; 95 % CI -2.0 to -0.7 from 1994 onward). This general change was mainly caused by the age group 65-74 years and by the higher incidence of squamous cell carcinoma histologic subtype. In females, lung cancer incidence increased over the entire study period by +4.2 % per year (95 % CI 3.1-5.4); this trend was mainly caused by the age group 55-64 years (APC = +7 %) and by adenocarcinoma incidence between women (APC = +6.8 %). Conclusion: Male lung cancer incidence rates have decreased in Granada, while female rates have increased overall especially in younger women. These trends may reflect the increased consumption of cigarettes in women especially during younger ages. Lung cancer prevention through tobacco control policies are therefore of utmost importance (AU)

Grosor coroideo macular en la neuropatía óptica isquémica anterior no arterítica / Macular choroidal thickness in non-arteritic ischemic optic neuropathy

OBJETIVO: Analizar el grosor coroideo macular (GCM) en la neuropatía óptica isquémica anterior no arterítica (NOIA-NA). MATERIAL Y MÉTODOS: Un total de 22 pacientes diagnosticados de NOIA-NA (22 ojos) y 42 sujetos sanos (42 ojos) fueron estudiados usando tomografía de coherencia óptica con técnica Enhanced Depth Imaging (EDI-OCT). Se realizó un escáner de una línea horizontal centrado en la fóvea 3 meses después del inicio de NOIA-NA. Se tomaron 3 medidas desde la parte posterior del epitelio pigmentario hasta la unión esclerocoroidea a intervalos de 500 μm en las 1.500 μm centrales de la mácula. Los resultados fueron analizados estadísticamente comparando la media de GCM entre grupos y correlacionando el GCM con otros parámetros oculares y sistémicos. RESULTADOS: Excepto en el error refractivo (p = 0,01), no hubo diferencias significativas en longitud axial (p = 0,53), edad (p = 0,88) ni en otros parámetros oculares ni epidemiológicos entre grupos. La media de GCM en la NOIA-NA y en el grupo control fue 236,21 ± 63,29 μm y 269,13 ± 52,28, respectivamente. La media del GCM fue significativamente más delgada en ojos con NOIA-NA que en sanos (p = 0,03). El adelgazamiento del GCM estuvo asociado con el diagnóstico de NOIA-NA después de ajustar por error refractivo (p = 0,04). CONCLUSIONES: Los ojos afectos con NOIA-NA mostraron un GCM significativamente más adelgazado que en sujetos sanos, después de ajustar por error refractivo

OBJECTIVE: To analyse macular choroidal thickness (MCT) in non-arteritic ischaemic optic neuropathy (NAION). MATERIALS AND METHODS: An analysis was made on 22 patients diagnosed with NAION (22 eyes) and 42 healthy controls (42 eyes) using enhanced-depth imaging of spectral-domain optical coherence tomography. A horizontal raster scan centred on the fovea was obtained per eye 3 months after the onset of NAION. Three measurements of MCT were obtained from the posterior edge of the retinal pigment epithelium to the choroid-sclera junction at 500 μm intervals. Statistical analysis was used to compare the mean MCT and to correlate MCT with other ocular and systemic parameters. RESULTS: Except for refractive error (P=.01), there were no statistically significant differences between both groups in axial length (P=.53), age (P=.88) and other epidemiological and ocular parameters. Mean MCT in NAION eyes and control group was 236.21 ± 63.29 μm and 269.13 ± 52.28, respectively. Mean MCT was significantly thinner in NAION eyes than in healthy eyes (P=.03). Thinner MCT, adjusted for refractive error, was associated with the diagnosis of NAION (P=.04). CONCLUSIONS: Eyes affected by NAION showed significantly thinner MCT compared with healthy control eyes after adjusting for refractive error

Relación entre función y volumen renal en la poliquistosis renal autosómica dominante: estudio transversal / Relationship between renal function and renal volume in autosomal dominant polycystic kidney disease: cross-sectional study

Objetivo. Determinar en pacientes con poliquistosis renal autosómica dominante la relación entre el volumen renal total (suma de ambos riñones, VRT) medido con resonancia magnética y la función renal; y su comportamiento según el sexo y la presencia de hipertensión arterial, hipercolesterolemia e hiperuricemia. Método. Estudio transversal en el que se incluyen pacientes con poliquistosis renal autosómica dominante que realizan revisiones periódicas en las consultas externas de Nefrología del Hospital Virgen de las Nieves de Granada, a quienes entre enero de 2008 y marzo de 2011 se les realizó una resonancia magnética para estimar el volumen renal. Resultados. Se evaluaron 67 pacientes (59,7% mujeres, edad media 48±14,4 años). Encontramos asociación positiva significativa entre VRT y creatinina sérica o urea, que resultó inversa frente al filtrado glomerular estimado por MDRD-4 y Cockcroft-Gault. Las mujeres mostraron un nivel medio de creatinina sérica y VRT inferior respecto al varón de forma significativa. Los subgrupos afectos de hipertensión arterial e hiperuricemia mostraron valores medios de creatinina sérica, urea y VRT más altos y filtrados glomerulares estimados inferiores. El subgrupo con hipercolesterolemia mostró valores medios de urea más altos y filtrados glomerulares estimados inferiores sin detectarse diferencias significativas respecto al VRT. Conclusión. El volumen de los riñones poliquísticos medido por resonancia magnética se asocia con la función renal, y puede ser útil como estudio complementario para monitorizar la progresión de la enfermedad. La presencia de hipertensión arterial, hiperuricemia o hipercolesterolemia están asociados a una peor función renal (AU)

Objective. To determine in patients with autosomal dominant polycystic kidney disease the relationship between total renal volume (the sum of both kidneys, TRV) as measured by magnetic resonance and renal function; and its behaviour according to sex and the presence of arterial hypertension, hypercholesterolaemia and hyperglycemia. Method. Cross-sectional study including patients with autosomal dominant polycystic kidney disease who underwent periodic reviews at Nephrology external consultations at Hospital de las Nieves de Granada, and who underwent an magnetic resonance to estimate renal volume between January 2008 and March 2011. Results. We evaluated 67 patients (59.7% women, average age of 48±14.4 years) and found a significant positive association between TRV and serum creatinine or urea, which was reversed compared with estimated glomerular filtration by MDRD-4 and Cockcroft-Gault. Women showed an average serum creatinine level and a significantly lower TRV level compared with males. Subgroups affected by arterial hypertension and hyperuricemia presented average values for serum creatinine and urea, higher for TRV and lower for estimated glomerular filtration. The hypercholesterolaemia subgroup showed higher average values for urea and lower for estimated glomerular filtration, without detecting significant differences compared with TRV. Conclusion. The volume of polycystic kidneys measured by magnetic resonance is associated with renal function, and can be useful as a complementary study to monitor disease progression. The presence of arterial hypertension, hyperuricemia or hypercholesterolaemia is associated with a poorer renal function (AU)

Unprocessed red meat and processed meat consumption and risk of stroke in the Spanish cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC).

BACKGROUND/OBJECTIVES: High intakes of unprocessed red or processed meat may increase the risk of stroke. We aimed to examine the association between unprocessed red meat, processed meat and total red meat consumption and risk of total stroke and ischaemic stroke. SUBJECTS/METHODS: Cox proportional hazards regression analyses were conducted based on the data for 41,020 men and women aged 29-69 years at baseline. RESULTS: During a mean follow-up of 13.8 years, 674 incident cases of stroke (531 ischaemic strokes, 79 haemorrhagic strokes, 42 subarachnoid haemorrhages and 22 mixed or unspecified events) were identified. After multiple adjustment, unprocessed red meat, processed meat and total red meat consumption were not correlated with incidence of total stroke or ischaemic stroke in either men or women. The hazard ratios (HRs) for unprocessed red meat and processed meat and risk of total stroke comparing the highest with the lowest quintiles were, respectively, 0.81 (95% confidence interval (CI) 0.54-1.21; P-trend=0.15) and 0.92 (95% CI 0.64-1.32; P-trend=0.82) in men and 1.21 (95% CI 0.79-1.85; P-trend=0.10) and 0.81 (95% CI 0.51-1.27; P-trend=0.17) in women. The HRs for unprocessed red meat and processed meat and risk of ischaemic stroke were, respectively, 0.80 (95% CI 0.51-1.25; P-trend=0.51) and 0.86 (95% CI 0.57-1.29; P-trend=0.77) in men and 1.24 (95% CI 0.74-2.05; P-trend=0.13) and 0.82 (95% CI 0.47-1.42; P-trend=0.31) in women. CONCLUSIONS: In the Spanish European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, unprocessed red meat and processed meat consumption were not associated with risk of stroke in men or women.
