Efectos de la danza en adultos mayores con riesgo de caídas. Revisión exploratoria / Effects of dance in older adults at risk of falls. Exploratory review

Resumen Introducción: Las caídas se consideran un problema de salud pública en los adultos mayores y su abordamiento debería ser multidimensional. La danza surge como una opción de intervención que permite integrar diferentes esquemas en la potenciación del movimiento. Objetivo: Determinar los efectos de la danza a nivel de equilibrio, función motora y actividades de la vida diaria en adultos mayores con riesgo de caer. Métodos: Revisión exploratoria en torno a cuáles son los efectos de la danza en adultos mayores con riesgo de caer para mejor el equilibrio, la marcha, la función motora y las actividades de la vida diaria. Las búsquedas se llevaron a cabo en PubMed, LILACS, Registro Central Cochrane de Ensayos Clínicos Controlados, PEDro, OTSeeker, artículos en texto completo en las diferentes bibliotecas virtuales (ProQuest, Ovid, Ebsco, Science Direct) y búsqueda manual. Resultados: Se encontraron 19 estudios que reportan sesiones de 45 a 60 minutos durante 12 semanas. La danza puede considerarse una intervención segura que disminuye significativamente la intervención de control para equilibrio y marcha en adultos mayores. Conclusiones: Los resultados de este trabajo sustentan que se puede emplear la danza como una opción interventiva en adultos mayores que presentan riesgo de caer.

Abstract Introduction: Falls are considered a public health problem in older adults, and their approach should be multidimensional. Dance emerges as an intervention option that allows different schemes to be integrated in movement enhancement. Objective: To determine the effects of dance on balance, motor function and activities of daily living in older adults at risk of falling. Methods: Exploratory review of the effects of dance in older adults at risk of falling in terms of balance, gait, motor function and activities of daily living. Searches were carried out in PubMed, LILACS, Cochrane Central Register of Controlled Trials, PEDro, OTSeeker, full text articles were searched in different virtual libraries (ProQuest, Ovid, Ebsco, Science Direct) and manual search was also carried out. Results: Nineteen studies were found, which report sessions of 45 to 60 minutes for 12 weeks. Dance can be considered a safe intervention that significantly decreases control intervention for balance and gait in older adults Conclusions: The results of this work support that dance can be used as an interventional option in older adults at risk of falling.

Major depressive disorder in Mexican medical students and associated factors: A focus on current and past abuse experiences.

BACKGROUND: Major depressive disorder (MDD) is highly prevalent among medical students (MS). Abuse experiences, as well as stress, are among the factors associated with MDD. However, their association with MDD in MS has been scarcely addressed. METHODS: A cross-sectional study design was used to evaluate the association between MDD and possible risk factors, focusing on current and past abuse experiences inside and outside the academic setting in a large representative MS sample (n = 1,068) using self-report instruments to assess MDD (PHQ-9) and perceived academic stress levels during exam season. RESULTS: Depressive symptom severity directly correlates with levels of perceived academic stress. The prevalence of MDD was 16.2%. A history of emotional abuse during childhood or adolescence, as well as most types of current abuse were associated with MDD. Multiple logistic regression analysis showed that current emotional abuse outside school had the strongest association with MDD in MS, followed by a personal history of depression and suicide attempt, a family history of depression, and perceived academic stress levels. LIMITATIONS: Cross-sectional design, participants represent a specific population, and other variables that could be associated with MDD: comorbid psychiatric disorders, current antidepressant treatment and protective factors (resilience and health-promoting coping strategies) were not evaluated. CONCLUSIONS: MDD is strongly associated with several risk factors that include most types of current and past abuse experiences. Timely identification of individuals at-risk will be critical to establish preventive strategies to limit the impact of MDD in MS and offer prompt therapeutic alternatives when needed.

Evolución clínica y de laboratorio de episodios de neutropenia febril en niños con cáncer, en un hospital de Colombia, período 2007-2009 / Clinical and laboratory evolution of the febrile neutropenia episodes in pediatric patients hospitalized in a Colombian hospital in 2007-2009

Introduction: Neutropenia is one of the most common complications in children with cancer, and it's the most important parameter to determine infection risk. In neutropenic patients the signs and symptoms could be scarce and in occasions fever could be the only symptom. For these reasons all patients with febrile neutropenia (FN) should be considered as if they had a possibly severe disease. Aim: To describe the clinical characteristics and laboratory parameters observed in cancer patients with FN attended at our hospital to perform a more rational management of this complication in the future. Patients and Methods: The clinical files accumulated during 36 months, belonging to patients aged 0 to 15 years that were hospitalized because of cancer and FN were reviewed. Results: In this series the source of fever was found in 48.6% of 105 NF episodes, and bacteria were isolated from blood or urine culture in 38%. The most frequent bacterial species recovered were methicillin susceptible S. aureus (20.8%) and ESBL negative E. coli (20.8%). Piperacillin/tazobactam was the most used first line antibiotic prescribed (87.6%) and meropenem was the second choice (18%). Granulocyte colony stimulating factor was used in 61.9% of the cases and episodes mortality rate was 6.7%. Conclusion: Clinical characteristics and bacteriological findings in our institution do not differ significantly from what has been described for pediatric cancer patients in other series.

Introducción: La neutropenia es una de las complicaciones más comunes en los niños con cáncer y el principal parámetro para determinar el riesgo de infección. Además, en estos pacientes los signos clínicos de infección pueden ser escasos y en ocasiones la fiebre es la única manifestación, por lo que todo paciente neutropénico y febril se debe manejar como si presentara una posible infección grave. Objetivo: Describir el comportamiento clínico y de laboratorio de los pacientes con neutropenia febril (NF) atendidos en nuestra institución para racionalizar el manejo futuro de esta complicación. Pacientes y Métodos : Se revisó los registros clínicos acumulados durante un período de 36 meses, de todos los pacientes de 0 a 15 años internados por cáncer y NF. Resultados: En este estudio se encontró el foco infeccioso en 48,6% de 105 episodios y se logró aislamiento bacteriano por hemocultivos y/o urocultivo en 38%. Las bacterias encontradas con mayor frecuencia fueron S. aureus sensible a meticilina (20,8%) y E. coli no productora de BLEE (20,8%). El antimicrobiano de primera línea más usado fue piperacilina/tazobactam (87,6%) y de segunda línea meropenem (18%). Se usó factor estimulante de colonias de granulocitos en 61,9% de los pacientes. La mortalidad asociada a estos episodios fue de 6,7%. Conclusión: Las características clínicas y hallazgos de laboratorio en nuestra institución no difieren mayormente de lo descrito en población pediátrica en otras series.
