Background: Diabetic Foot is a severe chronic complication of diabetes and an important factor in the morbidity of diabetic people, resulting in high health costs and increased risk of death., Objective: To analyze the incidence, prevalence, and risk factors associated with diabetic foot in people with type 2 Diabetes Mellitus., Method: Systematic literature review. Searches in MedLine via PubMed, LILACS, Web of Science, Scopus CINAHL, and Cochrane Library databases were performed. Inclusion of 52 studies. The R program, Metan packages, was used to calculate the meta-analysis. Given the heterogeneity of studies, the random effect was used to calculate the meta-analysis of risk factors., Results: The meta-analysis showed that the prevalence of diabetic foot was 14% in a hospital setting and 5% in a community setting. The overall prevalence and incidence were 9% and 4%, respectively. Significant risk factors included time of DM (odds ratio [OR] =1.46, confidence interval [CI], 0.36-2.57, P = 0.009), smoking (OR = 1.46, CI, 1.16 -1.85, P< .001), glycated hemoglobin (OR = 0.96, CI, 0.50; 1.42, P< .001), peripheral arterial disease (OR = 3.38, CI, 2.07; 5.53, P < .001) and peripheral neuropathy (OR = 5.88, CI, 2.39-14.45, P<.001)., Conclusion: Multidisciplinary monitoring, educational strategies, periodic foot examination for alterations, and early identification of risk factors are essential to prevent ulceration and reduce the disease burden., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Objective: To evaluate the effects of felted foam in the treatment of diabetic foot plantar ulcer., Method: Systematic review with meta-analysis. Research was conducted in Cochrane Library, PubMed, CINAHL, Science Direct, Web of Science, SCOPUS, IBECS and LILACS. Cochrane Collaboration Risk of Bias Tool was employed to evaluate risk of bias. The meta-analyses were calculated in the program Review Manager, while Grades of Recommendation, Assessment, Development and Evaluation was used for evaluating evidence quality., Results: Four clinical essays and two cohorts were included. Mean plantar pressure of individuals exposed to felt was reduced by 10.77 kilopascals (CI 95% -14.92, -6.62; p<0.001)., Conclusion: Higher reduction of plantar pressure was observed to be associated with the use of felt. Development of new models of relief orthosis with felted foam for plantar pressure is recommended, along with more clinical research elucidating related outcomes.
