Efeitos do tratamento com Hidrogel na cicatrização de úlceras venosas de membros inferiores: revisão sistemática

Chronic venous disease (CVD) is evident among the chronic diseases and affects the elderly population and primarily is responsible for leg ulcers in this population. The use of dressings in the care of a venous ulcer is a fundamental part of the treatment for healing, however, evidence to assist in choosing the best dressing is scarce. The main objective of this study was to evaluate the effectiveness of treatment with hydrogel in the healing of venous ulcers using search methods, synthesis of information and statistical research through a systematic review and meta-analysis. Randomized controlled trials were selected in the following databases: CENTRAL; DARE; NHS EED; MEDLINE; EMBASE; CINAHL. Beyond these databases three websites were consulted to identify ongoing studies: ClinicalTrials.gov, OMS ICTRP e ISRCTN. The primary outcomes were analyzed: complete wound healing, incidence of wound infection and the secondary were: changes in ulcer size, time to ulcer healing, recurrence of ulcer, quality of life of participants, pain and costs of treatment. Four studies are currently included in the review with a total of 250 participants. The use of hydrogel appears to be superior to conventional dressing, gauze soaked in saline, for the healing of venous leg ulcers; 16/30 patients showed complete healing of ulcers (RR 5,33, 95%CI [1,73,16,42]). The alginate gel was shown to be more effective when compared to the hydrogel dressing in reduction of the wound area; 61,2% (± 26,2%) with alginate e 19,4% (± 24,3%) with hydrogel at the end of four weeks of treatment. Manuka honey has shown to be similar to the hydrogel dressings in percentage of area reduction. This review demonstrated that there is no evidence available about the effectiveness of the hydrogel compared to other types of dressings on the healing of venous leg ulcers of the lower limbs, thus demonstrating the need of future studies to assist health professionals in choosing the correct dressing.

In order to evaluate the effect of levels of dehydrated cane juice sugar (DCJS) (0.0, 1.5, 3.0 and 4.5%) in the diet of European quail (Coturnix coturnix coturnix) on performance on performance, carcass characteristics and economical at 22 days of age indices, 192 quails cutting, were distributed in a completely randomized design with four treatments and six replicates of eight birds each There was no significant difference to the performance of quail in any of the periods. Quadratic effects of levels of DCJS on carcass weight (y = 173.71 + 4.2767x – 1.2644x², R² = 0.99), thigh-thigh more about (y = 36,055 + 1,1263x – 0,2256x², R² = 0.91) and abdominal fat (y = 3,3295 - + 0.8903x 0,19x2, R ² = 0,97) where the optimum levels were estimated 1,69; 2.50 and 2.34%, respectively. There was a linear effect descending of DCJS levels on weight breast with skin (y = 66.267 – 0.5653x, R² = 0.83) and without skin (y = 60.286 – 0.7193x, R² = 0.58). In economic analysis, one can observe higher profit to the producer with the use of conventional feed. However, between the levels of inclusion of sugar cane juice is observed that the level of 1.5% DCJS obtained the best results in economic analysis, obtaining only a difference of relative gross margin of 0.47% compared to conventional. It is recommended 1.69 and 2.50% DCJS for higher carcass, thigh + drumstick weight and lower percentage of abdominal fat quails, respectively.
