Percepción subjetiva del COVID-19: Una medida de evaluación integral para adolescentes y jóvenes / Subjective perception of COVID-19: A comprehensive assessment measure for adolescents and young people

Resumen La pandemia por COVID-19 es un evento adverso y factor de riesgo para la salud integral de los adolescentes y jóvenes, asociado a trastornos de estrés, ansiedad y depresión, sin embargo, la perspectiva ecológica plantea que la percepción del evento o situación juega un papel central en la adaptación y salud mental. Por otra parte, la detección de factores de riesgo-protección es la base de una intervención efectiva. El objetivo de este estudio fue construir una medida multidimensional válida y confiable para explorar la percepción subjetiva y las respuestas psicológicas de los adolescentes y jóvenes ante la pandemia por COVID-19. Se realizó un estudio instrumental en el que participaron 727 adolescentes de 13 a 24 años (M= 18.36; DE= 2.9) de la Ciudad de México. Se elaboró la Encuesta de Percepción Juvenil del COVID-19 (EPJ COVID-19) que fue aplicada en línea. Un análisis factorial por componentes principales (n= 410) arrojó una solución de ocho factores: Miedo y preocupaciones, Indicadores de estrés, Presiones escolares, Conductas preventivas, Cambios de rutinas, Dinámica familiar, Relajación y esparcimiento, y Socialización virtual (VE = 59.07%). Un análisis factorial confirmatorio con el método de máxima verosimilitud (n= 317) corroboró un modelo de ocho factores mostrando índices aceptables de ajuste, el cual también presentó una buena consistencia interna (α total= .863). Los resultados sugieren que la EPJ COVID-19 es una medida válida y confiable que puede ser usada para valorar de manera integral la percepción y respuestas de los adolescentes y jóvenes ante la pandemia para diseñar intervenciones basadas en evidencia.

Abstract The COVID-19 pandemic is an adverse event and risk factor for the integral health of adolescents and young people, associated with stress disorders, anxiety, and depression; however, the ecological-transactional perspective supposed that the perception of the event or situation plays a central role in adaptation and mental health. Likewise, detecting risk-protective factors is the basis for effective intervention The purpose of this study was to develop a valid and reliable multidimensional measure to explore the perception and psychological responses of young people to the pandemic. An instrumental study was carried out and 727 adolescents aged 13 to 24 years (M= 18.36; SD= 2.9) from Mexico City participated. The COVID-19's Youth Perception Survey (COVID 19's YPS) was constructed which was applied online. A factor analysis using the principal components (n= 410) yielded a solution of eight factors: Fear and worries, Stress indicators, School pressures, Preventive behaviors, Changes in routine, Family dynamics, Relaxation and leisure, and Virtual socialization (EV= 59.07%). A confirmatory factor analysis using the maximum likelihood method (n= 317) corroborated an eight-factor model showing acceptable fit index, and it also shows a good internal consistency (α total= .863). These results suggest that the Survey is a valid and reliable measure that can be used to comprehensively assess adolescents and youth perception and responses to the pandemic, providing data to designing evidence-based intervention.

Research progress on micro-osteoperforation-assisted orthodontic treatment / 口腔疾病防治

@#As a minimally invasive procedure, micro-osteoperforations (MOPs) achieve desired therapeutic effect with minimal surgical intervention. The operation is relatively simple, and the effect of assisted orthodontic treatment is obvious. However, due to the lack of long-term follow-up studies, there is no unified consensus on the long-term stability of the procedure. This article reviews the research status of MOPs, biological and biomechanical mechanisms, clinical applications and limitations. MOPs can shorten orthodontic treatment time and accelerate tooth movement by exerting regional acceleratory phenomena (RAP). At the same time, this procedure will not damage the health of the periodontal tissue, and the postoperative bleeding and postoperative reaction are minor. In addition, the pain and discomfort of patients were relatively mild and acceptable. However, it also has limitations, mainly including the limited time of the RAP effect of MOPs. Although this procedure is a minimally invasive surgery, there is still a risk of treating regional bone defects. At present, it is still necessary to increase the sample size and extend the follow-up time to evaluate the long-term stability of MOPs.

Subjective perception of surgeons with 4K resolution,three-dimensional systems in laparoscopic colorectal surgery:A self-filling questionnaire survey / 中国实用外科杂志

OBJECTIVE: To compare the subjective perception of surgeons with 4K-resolution(4K) and three-dimensional(3D) systems in the laparoscopic colorectal surgery.METHODS: A self-filling questionnaire survey wasdeveloped in the surgeons between August 2018 and February 2019 in Department of Gastrointestinal Surgery,RuijinHospital Affiliated to Shanghai Jiao Tong University School of Medicine. The data of questionnaires from surgeons indifferent position( major surgeons,first assistants,scopists) who performed laparoscopic colorectal surgeries with 4K,3D and 2D systems were collected. The questionnaires concerning asthenopia,motion sickness,topographical orientation,control coordination of visual angle,visual acuity,radiance,resolution ratio,depth description,color resolution,sense ofcontrols,optimum viewing distance,frames and refresh rate and contrast.RESULTS: There were 124 questionnairesscreened eligibility in the survey. Among them,there were 38 questionnaires for 2D group,43 questionnaires for 3D group and 43 questionnaires for 4 K group.(1)Overall comparison of the subjective scores:In the three groups,therewere significant difference in control coordination of visual angle,visual acuity,resolution ratio,depth description,color resolution,optimum viewing distance,frames andrefresh rate(P<0.05).(2)Subjective scores betweenmajor surgeons:In the three groups,there weresignificant difference in resolution ratio,depth description,color resolution and sense of controls(P<0.05);the most advantages could be found on resolution ratio andcolor resolution in 4 K group,and also could be found on depth description and sense of controls in 3 D group.(3)Subjective scores between first assistants: In the three groups,there were significant difference in asthenopia,controlcoordination of visual angle,resolution ratio,depth description,sense of controls,frames and refresh rate(P<0.05);In 4K group,it showed advantages on control coordination of visual angle and resolution ratio. Motion sickness was morepronounced in 3D group,but the most advantages could be found on depth description and sense of controls.(4)Subjective scores between scopists: In the three groups,there were significant difference in visual acuity,resolution ratio,depth description,sense of controls,optimum viewing distance and contrast(P<0.05). The most advantages could befound on visual acuity,resolution ratio and contrast in 4 K group,and also could be found on depth description and senseof controls in 3D group.CONCLUSION: Comparing with the traditional two-dimensional system during laparoscopiccolorectal surgery,4 K system could apply better resolution ratio,control coordination of visual angle,visual acuity andcolor resolution. 3D system could apply better depth description and sense of controls.

Percepção subjetiva do esforço em jogos oficiais de Futsal / Perception subjective effort in official Futsal games

O objetivo do presente estudo foi quantificar a intensidade dos esforços utilizando o método da PSE em partidas oficiais de futsal. A amostra foi constituída por 10 atletas do sexo masculino (16,5±2 anos) que participaram da etapa estadual dos Jogos Escolares da Juventude. Foi avaliado o comportamento da percepção subjetiva de esforço (PSE) em resposta à cinco jogos oficiais de futsal na categoria sub-17, sendo dois pela fase classificatória e três pela fase final da competição. A quantificação da carga interna foi determinada através do método da PSE da sessão (FOSTER et, al., 2001). Foram encontrados valores médios de 7,5 e 7,4 para as partidas da 1ª fase e 8,2, 8,7 e 8,9 para os jogos da fase final. Os resultados indicam cargas crescentes ao longo da competição, demonstrando que os jogos foram realizados com intensidades elevadas, compatíveis com intensidades de partidas de futsal analisadas utilizando outros indicadores, como frequência cardíaca e lactato. Pode-se concluir que a PSE é um método confiável para mensurar a intensidade dos esforços em partidas oficiais de futsal.(AU)

The aim of this study was to quantify the degree of effort using the method of PSE in official games of futsal. The sample consisted of 10 male athletes (16.5 ± 2 years) who participated in the state level of School Youth Games. The behavior of perceived exertion (RPE) in response to the five official games of futsal in the under-17 category was evaluated, two and three through the qualifying for the final stage of the competition. The quantification of the internal load was determined by the session SPE (Foster et, al. 2001) method. Average values of 7.5 and 7.4 for departures from 1st stage and 8.2, 8.7 and 8.9 for the finals matches were found. The results indicate increasing loads throughout the competition, demonstrating that the games were held at high intensities, consistent with intensities of futsal matches analyzed using other indicators such as heart rate and lactate. Can conclude that the PSE is a reliable method to measure the intensity of the efforts in official games of futsal.(AU)

Cognitive Development across Different Age Ranges in Late Adulthood / Desarrollo cognitivo de personas mayores en diferentes grupos de edad

This study sought to assess the cognitive development of older adults in different age groups, examining subjective perception of memory, verbal fluency, orientation in time and space, memory, and attention. The sample consisted of 121 subjects randomly selected, between the ages of 60 and 95 years, of both sexes and with varied educational attainment, took part in the study. Data were collected with a sociodemographic questionnaire, the Geriatric Depression Scale (GDS), the subjective Memory Complaint Questionnaire (MAC-Q), the Mini-Mental State Examination (MMSE), the Digit Span subtest of the Wechsler Adult Intelligence Scale, Revised (WAIS-R), the Buschke Selective Reminding Test, and a category verbal fluency test (animals). Results showed an inverse correlation between subjective perception of memory complaints and cognitive test performance. Age and educational attainment influenced cognitive test performance. Younger subjects and those with a higher educational attainment scored better on the verbal fluency test, MMSE, and digit span.

El actual estudio tiene como objetivo verificar el desarrollo cognitivo de las personas mayores en los diversas grupos de edad, examinando memoria, fluidez verbal, orientación secular y de espacio, memoria y atención subjetiva. Participaron en la muestra 121 personas mayores, seleccionadas aleatoriamente, entre 60 y 95 años, de ambos sexos y escolaridad variada. Para la recolección de los datos se utilizó un cuestionario sociodemográfico, Escala de Depressão Geriátrica (GDS), el cuestionario de quejas subjetivas de Memória (MAC-Q), Mini-Examinación de Estado mental (MEEM), la Secundario-prueba Span de Números (WAIS-R), la prueba libre del mandato selectivo y con las pistas (Buschke) y la fluidez verbal (categoría animal). Los resultados mostraron una correlación inversa entre la opinión subjetiva de las quejas de la memoria y las pruebas de los cognitivos. La influencia de la edad fue verificada y la escolaridad en las pruebas cognitivas, así, las personas mayores con menos edad y mayor escolaridad presentaron una mejor puntuación en la prueba de fluidez verbal, del MEEM y del palmo de números.
