Una Caracterización de la Arquitectura del Sueño en Adultos con Bruxismo del Sueño: Un Estudio Descriptivo Retrospectivo / Characterization of Sleep Architecture in Adults with Sleep Bruxism: A Retrospective Descriptive Study

Objetivo: Caracterizar la arquitectura del sueño en un grupo poblacional de adultos con bruxismo del sueño, en forma general y según sexo.Materiales y método: Estudio descriptivo retrospectivo, con un muestreo por intención de 33 polisomnografías que identificaban sujetos con bruxismo del sueño, según el “cut off” sugerido por Lavigne et al (25 eventos /hora), entre los años 2011-2019. Se consideraron las variables sexo, edad, peso, talla e índice de masa corporal (IMC). Se determinó la arquitectura del sueño en cuanto a duración de las etapas del sueño, micro despertares y eventos de bruxismo. Se realizó un análisis descriptivo de las variables y se compraron los resultados entre los sexos.Resultados: En el grupo poblacional 64% eran mujeres y 36% hombres. El promedio de edad fue de 32.5 años, de talla 1.65, de peso 68 kg, con un IMC promedio de 24.89 (peso normal). Los sujetos tuvieron un promedio de 387.6 horas de sueño, 270 minutos en NMOR y 10.8 en MOR, con un promedio de 50 micro despertares durante la noche y de 48.64 eventos de bruxismo por hora. Según sexo los valores en minutos fueron (p>0.05): NMOR (H: 316.2 – M:256.8); MOR (H: 105 – M:104.4); microdespertares (H :58.9 – M: 45.1); Eventos de BS/hora: (H:48.6 – M: 46.6) Los sujetos con BS durmieron, en promedio, un mayor número de minutos en decúbito lateral (196,59).Conclusión: Los sujetos con BS registran determinadas características en la arquitectura del sueño que deben considerarse. No hubo diferencia en la arquitectura del sueño según sexo. (AU)

Objective: To characterize sleep architecture in a population group of adults with sleep bruxism, in general and by sex. Materials and method: Retrospective descriptive study, with intentional sampling of 33 polysomnographies that identified subjects with sleep bruxism,according to the “cut off” suggested by Lavigne et al (25 events /hour/), between the years 2011-2019. The variables sex, age, weight, height and body mass index (BMI) were considered. Sleep architecture was determined in terms of duration of sleep stages, micro-awakenings, and bruxism events. A descriptive anlysis of the variables was carried out and the results were compared between the sexes.Results: In the population group, 64% were women and 36% men. The average age was 32.5 years, height 1.65 m, weight 68 kg, with an average BMI of 24.89 (normal weight). Subjects had an average of 387.6 minutes of sleep, 270 minutes in non-rapid eye movement (NREM) and 10.8 in rapid eye movement (REM), with an average of 50 micro-awakenings during the night and 48.64 bruxism events per hour. According to sex, the values in minutes were: NMOR (H:316.2 – M:256.8); MOR (H:105 – M:104.4); microawakenings (H:58.9 – M:45.1); BS events/hour: (H:48.6 – M: 46.6), no significant differences were found between them (p>0.05). Subjects with BS slept, on average, a greater number of minutes in the lateral decubitus position (196.59). Conclusion: Subjects with BS register certain characteristics in their sleep architecture that must be considered. There was no difference in sleeparchitecture according to sex.(AU)

Effectiveness of physical exercise programmes in reducing complications associated with secondary lymphoedema to breast cancer: a protocol for an overview of systematic reviews.

INTRODUCTION: Breast cancer-related lymphoedema (BCRL) is one of the most underestimated and debilitating complications associated with the treatment that women with breast cancer receive. Several systematic reviews (SRs) of different physical exercise programmes have been published, presenting disperse and contradictory clinical results. Therefore, there is a need for access to the best available and summarised evidence to capture and evaluate all the physical exercise programmes that focus on reducing BCRL. OBJECTIVE: To evaluate the effectiveness of different physical exercise programmes in reducing the volume of lymphoedema, pain intensity and improving quality of life. METHOD AND ANALYSIS: The protocol of this overview is reported following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols, and its methodology is based on Cochrane Handbook for Systematic Reviews of Interventions. Only those SRs involving physical exercise by patients with BCRL will be included, whether on its own or combined with other exercises or other physical therapy interventions.The outcomes of interest to be considered will be lymphoedema volume, quality of life, pain intensity, grip strength, range of motion, upper limb function and any adverse event. The MEDLINE/PubMed, Lilacs, Cochrane Library, PEDro and Embase databases will be searched for reports published from database inception to April 2023.Two researchers will perform study selection, data extraction and risk of bias assessment independently. Any discrepancy will be resolved by consensus, or ultimately, by a third-party reviewer. We will use Grading of Recommendations Assessment, Development and Evaluation System to assess the overall quality of the body of evidence. ETHICS AND DISSEMINATION: The results of this overview will be published in peer-reviewed scholarly journals and the scientific dissemination will take place in national or international conferences. This study does not require approval from an ethics committee, as it does not directly collect information from patients. PROSPERO REGISTRATION NUMBER: CRD42022334433.
