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)

Only half of the authors of overviews of exercise-related interventions use some strategy to manage overlapping primary studies-a metaresearch study.

OBJECTIVES: The conduct of systematic reviews (SRs) and overviews share several similarities. However, because the unit of analysis for overviews is the SRs, there are some unique challenges. One of the most critical issues to manage when conducting an overview is the overlap of data across the primary studies included in the SRs. This metaresearch study aimed to describe the frequency of strategies to manage the overlap in overviews of exercise-related interventions. STUDY DESIGN AND SETTING: A systematic search in MEDLINE (Ovid), Embase (Ovid), Cochrane Library, Epistemonikos, and other sources was conducted from inception to June 2022. We included overviews of SRs that considered primary studies and evaluated the effectiveness of exercise-related interventions for any health condition. The overviews were screened by two authors independently, and the extraction was performed by one author and checked by a second. We found 353 overviews published between 2005 and 2022 that met the inclusion criteria. RESULTS: One hundred and sixty-four overviews (46%) used at least one strategy to visualize, quantify, or resolve overlap, with a matrix (32/164; 20%), absolute frequency (34/164; 21%), and authors' algorithms (24/164; 15%) being the most used methods, respectively. From 2016 onwards, there has been a trend toward increasing the use of some strategies to manage overlap. Of the 108 overviews that used some strategy to resolve the overlap, ie, avoiding double or multiple counting of primary study data, 79 (73%) succeeded. In overviews where no strategies to manage overlap were reported (n = 189/353; 54%), 16 overview authors (8%) recognized this as a study limitation. CONCLUSION: Although there is a trend toward increasing its use, only half of the authors of the overviews of exercise-related interventions used a strategy to visualize, quantify, or resolve overlap in the primary studies' data. In the future, authors should report such strategies to communicate more valid results.

The influence of physical education at school on the attention of students aged 15-16 years / El impacto de la educación física en la escuela en la atención de los estudiantes de 15 a 16 años / O impacto da educação física na escola na atenção de estudantes de 15 a 16 anos

ABSTRACT Objectives: the influence of physical activity in physical education lessons on the attention indicators of schoolchildren. Material and Methods: 141 students, aged 15-16, who studied in the 9th grade, took part in the experiment. The main research method was the "Trondyke Test", which determines the level of attention development of students. The test was used before and after the physical education lesson 1 time per month for 5 months. Results: students who did not engage in physical education in the lesson were not able to significantly improve their performance in the test, which indicates a possible adaptation to the test after its first performance before the lesson. Students who were engaged in physical exercises could significantly increase the test results. Conclusion: the results obtained determine the effectiveness of the influence of a physical education lesson at school on the indicators of students attention. This study will serve as an additional motivation for students to engage in physical culture, since the impact of physical exercises has a positive effect not only on the development of physical qualities, but also on the attention of schoolchildren. Level of Evidence III; Retrospective Comparative Study.

RESUMEN Objetivos: la influencia de la actividad física en las clases de educación física en los indicadores de atención de los escolares. Material y métodos: Participaron en el experimento 141 escolares, de 15-16 años, que cursaban el noveno grado. El principal método de investigación fue la "Prueba de Trondyke", que determina el nivel de desarrollo de la atención de los escolares. La prueba se usó antes y después de la lección de educación física una vez al mes durante 5 meses. Resultados: los jóvenes que no participaron en educación física en la lección no pudieron mejorar significativamente su rendimiento en la prueba, lo que indica una posible adaptación a la prueba después de su primera actuación antes de la lección. Los escolares que realizaban ejercicios físicos pudieron aumentar significativamente los resultados de la prueba. Conclusión: los resultados obtenidos determinan la efectividad de la influencia de una lección de educación física en la escuela sobre los indicadores de atención de los escolares. Este estudio servirá como una motivación adicional para que los estudiantes participen en la cultura física, ya que el impacto de los ejercicios físicos tiene un efecto positivo no solo en el desarrollo de las cualidades físicas, sino también en la atención de los escolares. Nivel de Evidencia III; Estudio Comparativo Retrospectivo.

Assessment of activities and participation of people by rehabilitation-focused clinical registries: a systematic scoping review.

INTRODUCTION: Rehabilitation is considered a key intervention in health care. Clinical registries, defined as an organized system that uses observational methods to collect information to assess specific outcomes in a defined population, can contribute to assessing the impact of the rehabilitation intervention. This review aims to identify and describe rehabilitation-specific registry systems with an emphasis on identifying outcomes that enable the assessment of vital areas and activities of daily living. EVIDENCE ACQUISITION: A systematic scoping review was conducted. A systematic search was conducted up to August 2022 in MEDLINE/PubMed, Embase, Cochrane Library, Epistemonikos, and other search resources. Studies related to rehabilitation registries presented data on people with health problems that could limit their functioning were selected. The inclusion of studies/clinical registries was not limited by methodological design, year of publication, country, or language. The unit of analysis was rehabilitation registries. The measurement instruments used to assess the outcomes were explored to estimate the domain assessed from the vital areas related to functioning and disability as described by the International Classification of Functioning, Disability and Health (ICF). The vital areas were classified according to activities of daily living (ADLs). EVIDENCE SYNTHESIS: Seventy-one registries in rehabilitation were identified. The registries included a median of 3 (IQR 2-5) assessment instruments designed to assess the impact of different rehabilitation programs. In total, 137 different assessment scales or instruments were identified. Each rehabilitation registry assessed 6 (IQR 2-8) domains of the ICF, and 15.4% of registries assessed all domains. The most assessed domain was "Mobility" (89.7%), and the least assessed was "General Tasks and Demands" (25.6%). In addition, 92.3% of rehabilitation registries assessed basic ADLs, 76.9% advanced ADLs, and 71.8% instrumental ADLs. CONCLUSIONS: Although clinical registries do not claim to directly assess the impact of rehabilitation programs on people's functioning according to the ICF framework, it was identified that a low percentage of them assessed the nine vital areas through different outcome assessment instruments. However, most rehabilitation registries directly or indirectly assess some basic, instrumental, and advanced ADLs. The findings of this review highlight the need to improve the design of clinical registries focused on assessing the impact of rehabilitation programs to assess people in all areas of their lives.
