ABSTRACT
Objective: To test the hypothesis that undenatured type II collagen (UC-II) relieves pain, quality of life, and joint function in women aged from 60 to 80 years with knee osteoarthritis. Methods: 53 patients in the UC-II treatment group (for 90 days) and 52 in the control group (without UC-II) were evaluated at 1, 30, and 90 days regarding health-related quality of life, pain, and function with questionnaires, anthropometric data, alignment, range of motion, and radiographic analysis. Results: Quality of life increased significantly in the Physical domain in the treatment vs control group. Also, there was a difference between the first and the last evaluation on the pain visual analog scale (-3.8 ± 1.8 versus -1.3 ± 2.0) and on the WOMAC score (-9.5 ± 11.9 versus -1.3 ± 11.1). No variation in the temporal evolution of the Mental domain was found. Conclusion: Pain, joint stiffness, and quality of life (Physical domain) improved with the inclusion of UC-II for 90 days to the therapeutic toolbox for knee osteoarthritis in individuals aged 60 to 80 years. Level of evidence II, Comparative Prospective Study.
Objetivo: Testar a hipótese de que o colágeno não hidrolisado tipo II (UC-II) melhora a dor, qualidade de vida e função articular de indivíduos entre 60 e 80 anos com osteoartrite (OA) de joelho. Métodos: Cinquenta e três pacientes do grupo tratamento com UC-II (por 90 dias) e 52 do grupo controle (GC - sem UC-II) foram avaliados no tempo 0, 30 e 90 dias quanto à qualidade de vida em saúde, dor e função com os questionários, além de dados antropométricos, alinhamento, amplitude de movimento e análise radiográfica. Resultados: A qualidade de vida aumentou significantemente no domínio PCS no grupo tratamento versus controle. Houve ainda diferença entre a primeira e última avaliação na dor pela escala visual analógica (−3.8 ± 1.8 versus −1.3 ± 2.0) e no escore WOMAC (−9.5 ± 11.9 versus −1.3 ± 11.1). Não houve variação na evolução temporal do domínio MCS. Conclusão: Dor, rigidez articular e qualidade de vida (domínio físico) melhoram com a inclusão do UC-II por 90 dias ao arsenal terapêutico na OA do joelho em indivíduos de 60 a 80 anos. Nível de Evidência II, Estudo Prospectivo Comparativo.

ABSTRACT
OBJECTIVE: The germline breast cancer gene (BRCA) mutation confers a lifetime high risk for breast cancer (BC) and bilateral prophylactic mastectomy is the procedure which allows the highest risk reduction rate. Among other techniques, lipofilling (LF) can be used for breast reconstruction of these patients. However, there are some oncological safety concerns on the subject. The purpose of this study was to assess the oncological risk of LF in BRCA healthy patients. MATERIALS AND METHODS: A single institution case series was built including BRCA I/II mutated patients with no previous history of BC, who underwent bilateral prophylactic mastectomy followed by breast reconstruction with exclusive LF or combined with implants or latissimus dorsi flap. Data were collected regarding patient demographics, clinical information, reconstruction techniques used, and fat grafting details. RESULTS: From September 1999 till November 2017, we identified 18 BRCA carriers with no history of BC who had undergone bilateral prophylactic mastectomy, followed by breast reconstruction with LF. A total of 36 LF procedures were performed following an implant or latissimus dorsi flap, or as an exclusive fat grafting breast reconstruction. The average number of LF sessions was 1.4 with a mean volume of 108.8cc per breast. Median follow-up was 33.0 months after mastectomy and 24.5 months after the last LF intervention; no patients were diagnosed with BC during follow-up. CONCLUSION: Germline BRCA mutation is a high-risk plight for BC. However, despite the limited follow-up, no BC was detected.
