ABSTRACT Processing residues are still one of the main obstacles in the fishing industry due to waste and environmental impact. With that, ways of reusing these residues are researched to generate new products with different applications. The objective of this work was to develop and evaluate protein films obtained from mechanically separated meat (MSM) of Nile tilapia (Oreochromis niloticus) filleting residues. To get the films, the casting technique was used, varying their composition in relation to the amount of protein (1.0, 1.5 and 2.0%) and glycerol (0.0, 0.1 and 0.2%), creating a 32 factorial plan, with 9 treatments. The films were characterized in terms of color, opacity, water solubility, mechanical properties and water vapor permeability (WVP). In the end, a yield of 18.70% of Nile tilapia myofibrillar proteins (MPs) and a post-lyophilization protein content of 87.33% were obtained. It was concluded that the film that presented the best result in all the characteristics analyzed was the one with 1.0% of MPs and 0.1% of glycerol. impact applications MSM (MSM Oreochromis niloticus used 1.0, 10 1 0 (1.0 15 5 1. 2.0% 20 2 0.0, 00 (0.0 01 0. 0.2%, 02 0.2% , 0.2%) 3 plan treatments color opacity solubility WVP.

RESUMO Objetivo: Estudo comparativo entre tratamento com corticóide e aspirado de medula óssea concentrado (BMAC) para o tratamento de tendinopatias glúteas. Métodos: O ensaio clínico randomizado selecionou pacientes diagnosticados com tendinopatia glútea e os dividiu em dois grupos: (G1) aspirado de medula óssea concentrada e (G2) injeção de corticosteróide. Resultados: Foram selecionados 48 pacientes, dos quais 40 foram monitorados por 6 meses, com melhora nos escores nos dois grupos. Os pacientes que foram submetidos ao tratamento com BMAC tiveram uma melhora estatisticamente significativa nos escores de EVA e nos escores de Lequesne em comparação ao tratamento padrão. Houve uma melhora na avaliação da qualidade de vida em ambos os grupos, sem diferença estatisticamente significativa. Conclusão: O aspirado de medula óssea concentrada surge como uma alternativa ao tratamento padrão da tendinopatia glútea, provando ser uma técnica segura e com resultados promissores quando combinada à terapia comportamental de equipe multidisciplinar. Nível de Evidência II, O ensaio clínico randomizado.

ABSTRACT Objective: To compare bone marrow aspirate concentrate (BMAC) with the standard treatment for gluteal tendinopathies. Methods: 48 patients diagnosed with gluteal tendinopathy at a university hospital were selected by a randomized clinical trial and divided into two groups: (G1) bone marrow aspirate concentrate and (G2) corticosteroid injections. Results: 40 of the 48 selected patients were monitored for six months and both groups showed better scores. Visual analog scale (VAS) scores and Lequesne index were statistically significant higher in patients submitted to BMAC treatment when compared to standard treatment. Both groups improved their quality of life, without statistically significant difference. Conclusion: BMAC constitutes an alternative to gluteal tendinopathy standard treatment, proving to be a safe technique with promising results when combined with multidisciplinary team behavioral therapy. Level of Evidence II, Randomized Clinical Trial.

INTRODUCTION Adult gluteal tendinopathy is part of a group of pathologies of Greater Trochanteric Pain Syndrome (GTPS). This disorder is characterized by pain, functional limitation and loss of local strength. The diagnosis is made from clinical examination associated with complementary exams (Ultrasound or Magnetic Resonance). OBJECTIVE Comparative study between standard treatment and bone marrow aspirate concentrate (BMAC) for the treatment of gluteal tendinopathies. The randomized clinical trial selected patients diagnosed with gluteal tendinopathy at a university hospital and divided them into two groups: (G1) bone marrow aspirate concentrate and (G2) Corticosteroids injection. RESULTS 48 patients were selected, of which 40 were monitored for 06 months, with an improvement in scores in both groups. Patients who were submitted to the BMAC treatment had a statistically significant improvement in VAS scores and Lequesne scores compared to standard treatment. There was an improvement in the assessment of the quality of life in both groups with no statistically significant difference. CONCLUSION BMAC arises as an alternative to the standard treatment of gluteal tendinopathy, proving to be a safe technique and with promising results when combined with multidisciplinary team behavioral therapy.

INTRODUÇÃO A tendinopatia glútea adulta faz parte de um grupo de patologias da Síndrome Dolorosa Trocantérica (SDT). Esse distúrbio é caracterizado por dor, limitação funcional e perda de força local. O diagnóstico é feito a partir de exames clínicos associados a exames complementares (ultrassonografia ou ressonância magnética). OBJETIVO Estudo comparativo entre tratamento com corticóide e aspirado de medula óssea concentrado (BMAC) para o tratamento de tendinopatias glúteas. MATERIAL E MÉTODOS O ensaio clínico randomizado selecionou pacientes diagnosticados com tendinopatia glútea e os dividiu em dois grupos: (G1) aspirado de medula óssea concentrada e (G2) injeção de corticosteróide .
