RESUMO

BACKGROUND: Patellar instability is a common and disabling clinical condition. Treatment of acute primary patellar dislocation aims to reduce the risk of recurrence or painful subluxation and improve function. However, the actual clinical efficacy of any management modality following an acute dislocation has never been demonstrated in prospective or retrospective studies, and the optimal way in which the various management modalities should be used is at best unclear. METHODS: A search was conducted in PubMed, Bireme and Embase databases. Inclusion criteria followed the acronym PICOS, (P) subjects with patellar instability, (I) therapeutic interventions, (C) placebo or control or surgical treatments, (O) rate of dislocations and function, and (S) clinical trials. The Medical Subject Headings (MeSH) terms used were: (("patellar instability") OR ("patellar dislocation")) AND ((physiotherapy) OR (rehabilitation) OR ("conservative treatment") OR (therapy) OR (therapeutic)). The risk of bias was analysed using the PeDRO scale. RESULTS: Seven randomized controlled trials including 282 patients were considered. The quality of studies detailing the results of conservative treatment was higher than that of surgical procedures, but all studies have relatively low methodological quality. Four studies compared physiotherapeutic interventions with surgical procedures, and three studies compared conservative intervention techniques. CONCLUSION: An unstructured lower limb physical therapy programme evidences similar outcomes to specific exercises. Surgical management is associated with a lower rate of re-dislocation; however, whether surgery produces greater functional outcomes than conservative management is still unclear. The use of a knee brace with a limited range of motion, stretching and neuromuscular exercises are the most commonly recommended physiotherapy methodologies.

RESUMO

Isokinetic tests have been highly valuable to athletic analysis, but their cost and technical operation turn them inaccessible. The purpose of this study was to verify the correlation between unilateral countermovement jump variables and isokinetic data. Thirty-two male professional soccer players were subjected to the isokinetic testing of both knee extensors and flexors in concentric and eccentric muscle contractions. They also executed unilateral countermovement vertical jumps (UCMJ) to compare maximum height, ground reaction force, and impulse power with isokinetic peak torque. Data analysis was conducted through Pearson correlation and linear regression. A high correlation was found between dominant unilateral extensor concentric peak torque and the UCMJ maximum height of the dominant leg. The non-dominant leg jump showed a moderate correlation. No other variable showed statistical significance. Linear regression allowed the generation of two formulae to estimate the peak torque from UCMJ for dominant and non-dominant legs. Although few studies were found to compare our results, leading to more studies being needed, a better understanding of the unilateral countermovement jump may be used in the future as a substitute to the expensive and technically demanding isokinetic testing when it is unavailable, allowing the assessment of lower limb physical asymmetries in athletic or rehabilitation environments.

RESUMO

Introdução: O ambiente oncológico, por si só, já é um local que frequentemente expõe os profissionais que ali trabalham a enfrentar vivências e experiências de sofrimento no dia a dia pelas características da própria patologia. Objetivo: Verificar e analisar as evidências do impacto da doença pelo coronavírus 2019 (covid-19) sobre a saúde mental de profissionais de saúde que atuam na área da oncologia. Método: Pesquisa realizada nas bases Web of Science, PubMed, MEDLINE via Ovid, CINAHL via EBSCO e Embase, e avaliação segundo a metodologia STROBE. Resultados: Foram incluídos nove artigos, evidenciando a fragilidade do sistema de saúde do mundo inteiro diante de uma pandemia e afetando a saúde tanto dos pacientes quanto dos profissionais de saúde, em especial os que estavam na chamada "linha de frente". Esses fatores provocaram altas cargas de tensão, medo, insegurança e insatisfação profissional. Conclusão: Estratégias de prevenção de doenças emocionais relacionadas ao trabalho específico dos profissionais de saúde que atuem na área da oncologia devem ser implementadas para preservar a saúde mental dos profissionais

Introduction: The oncological environment, by itself, is a place that often exposes professionals who work there to cope with experiences and suffering in their daily work due to the characteristics of the pathology. Objective: To verify and analyze the evidence of the impact of the coronavirus disease 2019 (COVID-19) pandemic on the mental health of oncology professionals. Method: Search at the databases Web of Science, PubMed, MEDLINE via Ovid, CINAHL via EBSCO and Embase, and evaluation according to the methodology STROBE. Results: A total of 9 articles were included, which highlighted the fragility of the health system worldwide in face of the pandemic, affecting the health of both patients and professionals, especially those who were in the "front line". These factors provoked high burden of tension, fear, insecurity and professional dissatisfaction. Conclusion: Strategies for the prevention of emotional illnesses related to the specific work of oncology health professionals must be implemented to ensure their mental health

Introducción: El entorno oncológico, por sí mismo, ya es un lugar que muchas veces expone a los profesionales que allí actúan a enfrentarse a vivencias y sufrimientos en su quehacer diario debido a las características de la propia patología. Objetivo: Verificar y analizar la evidencia sobre el impacto de la enfermedad por coronavirus 2019 (covid-19) en la salud mental de los profesionales de la salud que trabajan en el sector oncológico. Método: Búsqueda en las bases de datos Web of Science, PubMed, MEDLINE vía Ovid, CINAHL vía EBSCO y Embase, evaluada metodológicamente por STROBE. Resultados: Se incluyeron un total de nueve artículos que ponían de manifiesto la fragilidad del sistema sanitario en todo el mundo ante una pandemia y que afectaba a la salud tanto de los pacientes como de los profesionales que trabajaban en los sectores sanitarios, especialmente los que estaban en la llamada "primera línea". Estos factores provocaron altas cargas de tensión, miedo, inseguridad e insatisfacción profesional. Conclusión: Estrategias para la prevención de enfermedades emocionales relacionadas con el trabajo específico de los profesionales de la salud que actúan en la área de la oncología deben desarrollarse en entornos de salud, con el fin de garantizar la salud mental de los profesionales
