[Non-pharmacological interventions to reduce depressive symptoms in women with breast cancer]. / Intervenciones no farmacológicas para reducir síntomas depresivos en mujeres con cáncer de mama.

OBJECTIVE: To describe and discuss the results of non-pharmacological interventions (NPI) adjuvants in the treatment of depressive symptoms among women with breast cancer (BC). MATERIALS AND METHODS: A systematic review on NPI was performed, which was applied to patients with cancer and depressive symptoms in seven databases. The review was limited from January 1, 2006 to December 31, 2017 and to English, Spanish and Portuguese languages. The medical descriptors used were "breast neoplasm" and "depression". RESULTS: There are several NPI that are able stimulate the physical or psychosocial dimensions. In this article we propose a classification based on nine identified therapeutic strategies, among which exercise, psychotherapy and yoga with meditation stand out. CONCLUSIONS: Based on the available evidence, we concluded that psychotherapy and yoga with meditation reduce depressive symptoms in patients with CaMa. More research is needed to determine the magnitude of the reduction of depressive symptoms, according to their severity, presence of comorbidities and diversity of INF.

OBJECTIVE: Describir y discutir los resultados de las intervenciones no farmacológicas (INF) adyuvantes en el tratamiento de los síntomas depresivos entre mujeres con cáncer de mama (CaMa). MATERIALS AND METHODS: Se realizó una revisión sistemática sobre INF, aplicadas a pacientes con cáncer y síntomas depresivos en siete bases de datos. La revisión se limitó del 1 de enero de 2006 al 31 de diciembre de 2017 y a los idiomas inglés, español y portugués. Los descriptores médicos empleados fueron "breast neoplasm" y "depression". RESULTS: Existen diversas INF que pueden estimular principalmente las dimensiones físicas o psicosociales. En este artículo se propone una clasificación basada en nueve estrategias terapéuticas identificadas, entre las que sobresalen el ejercicio, la psicoterapia y el yoga con meditación. CONCLUSIONS: Con base en la evidencia disponible, se concluye que la psicoterapia y yoga con meditación reducen los síntomas depresivos en pacientes con CaMa. Se requiere mayor investigación para determinar la magnitud de la reducción de los síntomas depresivos, de acuerdo con su gravedad, presencia de comorbilidades y diversidad de INF.

Non-pharmacological therapies for depressive symptoms in breast cancer patients: Systematic review and meta-analysis of randomized clinical trials.

OBJECTIVE: Depressive symptoms are common comorbidities among breast cancer (BC) patients. Non-pharmacological therapies (NPTs) such as exercise and psychotherapy may reduce depressive symptoms; however, the evidence is inconclusive. The objective of this study is to evaluate if NPTs reduce depressive symptoms among BC patients. METHODS: A systematic review and meta-analysis of randomized clinical trials (RCTs) of NPTs for BC patients were performed. A literature search was conducted from eight databases in English, Portuguese and Spanish from 2006 to 2017. Inclusion criteria were: RCTs that evaluated depressive symptoms as a primary or secondary outcome that did not include pharmacological interventions and did include a non-intervened control group, with at least 30 participants in non-terminal BC stage with no current psychiatric illness. A meta-analysis for each NPT was performed with DerSimonian and Laird's method for the random effects model. Sensitivity analyses were conducted. Heterogeneity and publication bias were assessed. RESULTS: A total of 41 eligible RCTs were identified. Overall, NPTs significantly reduced depressive symptoms (Summary standardized mean difference (SMD) = -0.516; 95%CI: -0.814, -0.218; I2 = 96.2). Of the types of NPTs, psychotherapy significantly reduced depressive symptoms (Summary SMD = -0.819; 95% CI: -1.608, -0.030; I2 = 91.53). A significant difference emerged for Mindfulness (Summary SMD = -0.241; 95% CI: -0.412, -0.070; I2 = 28.6%) and yoga (Summary SMD = -0.305; 95% CI: -0.602, -0.007; I2 = 41.0%) when the heterogeneity was reduced. No evidence of publication bias was observed. CONCLUSIONS: Psychotherapy and mind-body therapies may reduce depressive symptoms in women with BC. Laughter and couples therapy warrant attention in future studies.

[Effect of weather temperature on hospital emergencies in the Region of Murcia, Spain, throughout the 2000-2005 and its use in epidemiological surveillance]. / Efecto del calor sobre el número de urgencias hospitalarias en la Región de Murcia durante los veranos del período 2000-2005 y su uso en la vigilancia epidemiológica.

BACKGROUND: The effect of the weather temperature on mortality has been studied more in depth than its effect on morbidity. In Murcia, the number of daily emergencies and the cases of heat stroke for which care is provided at the hospitals in this Region have been studied. OBJECTIVE: to evaluate the effect that the weather temperature has on the number of hospital emergencies and the use of these indicators for the surveillance of hot weather-related morbidity. METHODS: The effect of the weather temperature on the number of summertime emergencies (2000-2005) has been studied by estimating the percentage increase in emergencies when the weather temperature thresholds established by the Ministry of Health and Consumer Affairs (Max. 38 degrees C and Min. 22.4 degrees C) are exceeded, and by each degree of temperature rise. Results have been stated as Relative Risk (RR) with a 95% CI. A comparison has been drawn between the heat strokes notified and the hospital admissions recorded in the Minimum Basic Data Set at Hospital Discharge (MBDS). RESULTS: Within the 2000-2005 period, the number of emergencies rose by 1.6% on those days when the minimum temperature for the day was above 22.4 degrees C (RR: 1.016; 95% CI 1.0076-1.0244) and by 0.21% for each degree of rise in the minimum temperature for the day (RR: 1.0021, 95% CI 1.0000-1.0044). A total of 38% of the heat strokes admitted to hospital were not reported, of which 40% had occupational exposure. CONCLUSIONS: The minimum temperature for the day could have a greater effect in Murcia than the maximum for the day. Based on the current thresholds, the number of emergencies/day does not seem to be a suitable indicator for monitoring the effect of the weather temperature, information on the diagnosis and the age being needed. Heat strokes provide partial information on the impact, but highlight less-considered population groups at risk.

[Correspondences from 10th to 9th Revision of the International Classification of Diseases in the causes of death lists of the National Institute of Statistics and the Regional Health Authority of Murcia in Spain]. / Correspondencias entre CIE-10 y CIE-9 para las listas de causas de muerte del Instituto Nacional de Estadística y de la Región de Murcia.

BACKGROUND: Different countries have conducted comparability studies between Revisions 10 and 9 of the International Classification of Diseases for aggregate lists of causes of death. In Spain, the COMPARA project was aimed at evaluating the impact of the revision change. METHODS: Descriptive cross-sectional epidemiological study of 88,048 deaths recorded in Spain in 1999 with the underlying cause of death doubled coded in ICD-9 and ICD-10. The theoretical correspondences between the ICD on the lists of the National Institute of Statistics and Murcia are established. The comparability rates and their confidence intervals, and the total kappa index were calculated. RESULTS: A decline in infectious diseases (-1.7%) and viral hepatitis, (-12.3%) declined under Tenth revision, while AIDS showed an increase (5.7%). Neoplasms increased a little (0.3%) with the inclusion of the Mielodisplasic Syndrome (55.2%). Diabetes mellitus is increased (2.1%). Mental disorders declined on dementia being shifted to Alzheimer's disease (28.6%). Cardiovascular diseases dropped slightly (-1.4%), without any impact on cerebrovascular diseases, although acute myocardial infarct decreased (-0.6%) while ischemic heart disease increased (0.3%). Pneumonia decreased (-12.5%) and hepatic cirrhosis grows (4.3%). Ill-defined conditions increased due to cardiorespiratory insufficiencies. The external causes show no change without including the accuracy of ICD-9. The National Institute of Statistics 102 groups list obtained a total kappa index of 95.4%, similar to the Murcia variants. CONCLUSIONS: Although ICD-10 has a lesser overall impact, the significant comparability rates of the causes of death groups between the revisions with important absolute differences should be taken into account.

Interpretando correctamente en salud pública estimaciones puntuales, intervalos de confianza y contrastes de hipótesis / Accurate interpretation of point estimates, confidence intervals, and hypothesis tests in public health

El presente ensayo trata de aclarar algunos conceptos utilizados habitualmente en el campo de investigación de la salud pública, que en numerosas situaciones son interpretados de manera incorrecta. Entre ellos encontramos la estimación puntual, los intervalos de confianza, y los contrastes de hipótesis. Estableciendo un paralelismo entre estos tres conceptos, podemos observar cuáles son sus diferencias más importantes a la hora de ser interpretados, tanto desde el punto de vista del enfoque clásico como desde la óptica bayesiana.
