RESUMO

ABSTRACT Objective: To analyze the effect of Unna's Boot on the healing of venous ulcers compared to other therapies. Methods: Systematic Review carried out in the databases Scopus, Embase, Cochrane Library, Web of Science, PubMed, Cumulative Index of Nursing and Allied Health Literature, Latin American and Caribbean Literature in Health Sciences, and grey literature. Population - adult patients with venous ulcers; Intervention- Unna's Boot (UB); Control - other compression therapies (CT); Outcome- healing; Designs- randomized clinical trial, cohort study, and case control, published from 2001 to 2024. The effect of the intervention, risk of bias, and quality of evidence were evaluated. Registered with PROSPERO (CRD42021290077). Results: A total of 39 studies were included, with 5.151 patients. The majority (71.8%) were randomized controlled trials (RCT). UB was used as intervention/control in eight studies. When comparing CTs, only 1 study with UB showed a superior effect (p < .001) in healing, compared with high compression elastic bandage. In the quality of evidence analysis, 27 studies were assessed as having a high risk of bias. Conclusion: No superiority of UB was found in the healing of venous ulcers when compared to other CTs.

RESUMEN Objetivo: Analizar el efecto de la Bota de Unna en la cicatrización de úlceras venosas en comparación con otras terapias. Métodos: Revisión sistemática realizada en las bases de datos Scopus, Embase, Biblioteca Cochrane, Web de la Ciencia, PubMed, Índice acumulativo de literatura de enfermería y salud afines, Literatura Latinoamericana y del Caribe en Ciencias de la Salud, y literatura gris. Población - pacientes adultos con úlceras venosas; Intervención- Bota de Unna (BU); Control: otras terapias de compresión (TC); Resultado- curación; Diseños: ensayo clínico aleatorizado, estudio de cohorte y casos y controles, publicado del 2002 al 2023. Se evaluaron el efecto de la intervención, el riesgo de sesgo y la calidad de la evidencia. Registrada en PRÓSPERO (CRD42021290077). Resultados: Se incluyeron 39 estudios, con 5.151 pacientes. La mayoría (71,8%) fueron ensayos controlados aleatorios (ECA). La BU se utilizó como intervención/control en ocho estudios. Al comparar TC, sólo 1 estudio con BU mostró un efecto superior (p < .001) en la curación, en comparación con el vendaje elástico de alta compresión. En el análisis de la calidad de la evidencia, se evaluó que 27 estudios tenían un alto riesgo de sesgo. Conclusión: No se encontró superioridad de la BU en la curación de úlceras venosas en comparación con otras TC.

RESUMO Objetivo: Analisar o efeito da Bota de Unna na cicatrização de úlceras venosas em comparação com outras terapias. Métodos: Revisão Sistemática realizada nas bases de dados Scopus, Embase, Cochrane Library, Web of Science, PubMed, Cumulative Index of Nursing and Allied Health Literature, Literatura Latino-Americana e do Caribe em Ciências da Saúde, e de literatura cinzenta. População- pacientes adultos com úlcera venosa; Intervenção- Bota de Unna (BU); Controle- outras terapias compressivas (TC); Desfecho- cicatrização; Delineamentos- ensaio clínico randomizado, estudo de coorte e caso controle, publicados de 2002 a 2023. Avaliaramu-se efeito da intervenção, risco de viés e qualidade da evidência. Registrada no PROSPERO (CRD42021290077). Resultados: Foram incluídos 39 estudos, com 5.151 pacientes. A maioria (71,8%) era ensaios clínicos randomizados (ECR). A BU foi utilizada como intervenção/controle em oito estudos. Na comparação entre TC, somente 1 estudo com BU apresentou efeito superior (p < .001) na cicatrização, comparado com atadura elástica de alta compressão. Na análise de qualidade da evidência, 27 estudos foram avaliados com alto risco de viés. Conclusão: Não foi encontrada superioridade da BU na cicatrização de úlceras venosas quando comparada com outras TC.

RESUMO

Introduction: Thyroid hormones exert multiple physiological effects essential to the maintenance of basal metabolic rate (BMR), adaptive thermogenesis, fat metabolism, growth, and appetite. The links between obesity and the hormones of the thyroid axis, i.e., triiodothyronine (T3), thyroxine (T4), and thyrotropin (TSH), are still controversial, especially when considering children and adolescents. This population has high rates of overweight and obesity and several treatment approaches, including nutritional, psychological, and physical exercise interventions have been used. Understanding the importance of the hormones of the thyroid axis in the recovery from overweight and obesity may help directing measures to the maintenance of a healthy body composition. The present scoping review was carried out to analyze studies evaluating these hormonal levels throughout interventions directed at treating overweight and obesity in children and adolescents. The main purpose was to ascertain whether the hormones levels vary during weight loss. Methods: We selected for analysis 19 studies published between 1999 and 2022. Results: Most of the studies showed that changes in different anthropometric indicators, in response to the multidisciplinary interventions, correlated positively with free T3 (fT3), total T3 (TT3), and TSH. With respect to free T4 (fT4) and total T4 (TT4). Discussion: The most common finding was of unchanged levels and, hence, no significant association with weight loss. Moreover, thyroxine supplementation has failed to affect the response to the interventions. Further studies are necessary to elucidate the relevance of the variations in hormone levels to the establishment of overweight/obesity and to the recovery from these conditions in children/adolescents.

RESUMO

INTRODUCTION: In two previous studies, the quality of randomized controlled trials (RCTs) with the participation of at least one plastic surgeon was evaluated in two periods: 1966-2003 and 2004-2008. OBJECTIVE: To evaluate the evolution of the quality of RCT publications by plastic surgeons in the subsequent 5-year period, from 2009 to 2013. METHODS: RCTs published from 2009 to 2013 in English with the participation of at least one plastic surgeon were identified by electronic search and classified for concealment of allocation by two independent evaluators. The studies with adequate allocation concealment had their quality evaluated by two evaluators using the Delphi List and the Jadad Quality Scale. RESULTS: Of the 6997 identified studies, 261 were classified as to concealment of allocation. Of these, 43 (16.47%) had adequate allocation concealment. According to the evaluation in the Delphi List, there was an improvement, in relation to 1966-2003, in the items "most important characteristics of the prognosis" (p < 0.001), "use of independent evaluator" (p = 0.0029), and "measures of variability and point estimate for the primary variable" (p = 0.0057); there was no difference in relation to 2004-2008. Regarding the Jadad Quality Scale, there was an increase in scores in relation to 1966-2003 (p < 0.0004) but not in relation to the 2004-2008 period. CONCLUSION: There was no difference in the quality of publications of RCTs by plastic surgeons in the period 2009-2013 compared to the previous 5 years (2004-2008), but both periods presented higher quality than the period 1966-2003.
