Effects of the use of bioceramic wraps in patients with lower limb venous ulcers: A randomized double-blind placebo-controlled trial / 中西医结合学报

BACKGROUND@#Venous ulcer represents the most advanced stage of chronic venous insufficiency. It is an important public health problem and has a significant impact on patients' quality of life due to chronic pain, inability to work, need for hospitalization and frequent outpatient follow-up.@*OBJECTIVE@#We investigated the treatment benefits of far-infrared ceramic (cFIR), in a 90-day study of lower limb venous ulcers and looked at ulcer healing scores, quality of life, serum bio-markers of oxidative stress and antioxidant defense enzymes.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS@#This is a randomized double-blind placebo-controlled study conducted in the Vascular Surgery Service of a hospital located in the northwest region of the State of Rio Grande do Sul, Brazil. We included patients with lower limb venous ulcers who were randomized to use either a bioceramics wrap or a placebo wrap for 90 days.@*MAIN OUTCOME MEASURES@#The following evaluations were conducted at baseline and after 15, 30, 60 and 90 days: ulcer healing score, quality of life, and serum markers of oxidative stress and antioxidant enzyme activity.@*RESULTS@#Patients (n = 24) with lower limb venous ulcers were randomized into two treatment groups. cFIR decreased the ulcer size on day 30 (P = 0.042) and 90 (P = 0.034) and the total ulcer healing scale scores on day 30 (P = 0.049) and 90 (P = 0.02) of the treatment, when compared to baseline. Additionally, cFIR improved tissue type (epithelial tissue) on day 60 (P = 0.022) when compared to baseline evaluation.@*CONCLUSION@#cFIR clinically improved ulcer healing in patients with lower limb venous ulcers.@*TRIAL REGISTRATION@#RBR-8c7xzn on ReBEC.

Effects of ceramic garments on 10-km running performance

Aims: The use of electromagnetic waves by phototherapy to skeletal muscle presents potential ergogenic effects. The aim of this study was to analyze the effect of using bioceramic clothes on performance, heart rate (HR) and rating of perceived exertion (RPE) during a 10 km race. Our hypothesis is that the use of such clothes modifies these variables. Methods: Participants were 10 runners (27.9 ± 4.2 years) who performed two 10 km performances on track under different intervention conditions: bioceramic garments (CER) and placebo garments (PLA). The mean velocity (MV), HR and rate of perceived exertion (RPE) were monitored at each trial. Additionally, partial MV was calculated in three phases: (1) start (first 400 m), (2) middle (400-9600 m) and (3) end (last 400 m). Results: MV in CER condition was significantly higher than in PLA condition (11.8 ± 1.0 km·h-1 vs 11.4 ± 1.2 km·h-1; F = 6.200; P = 0.034; ŋp² = 0.408). HR and RPE values in CER condition were not different from PLA condition. Conclusions Our main finding was that the use of bioceramic clothes (CER) increased MV when compared to the PLA condition. Based on these results, bioceramic may be used as an ergogenic resource to increase performance.(AU)

Antibacterial effect of citrus press-cakes dried by high speed and far-infrared radiation drying methods

In this study, the antibacterial effect was evaluated to determine the benefits of high speed drying (HSD) and far-infrared radiation drying (FIR) compared to the freeze drying (FD) method. Citrus press-cakes (CPCs) are released as a by-product in the citrus processing industry. Previous studies have shown that the HSD and FIR drying methods are much more economical for drying time and mass drying than those of FD, even though FD is the most qualified drying method. The disk diffusion assay was conducted, and the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined with methanol extracts of the dried CPCs against 11 fish and five food-related pathogenic bacteria. The disk diffusion results indicated that the CPCs dried by HSD, FIR, and FD prevented growth of all tested bacteria almost identically. The MIC and MBC results showed a range from 0.5-8.0 mg/mL and 1.0-16.0 mg/mL respectively. Scanning electron microscopy indicated that the extracts changed the morphology of the bacteria cell wall, leading to destruction. These results suggest that CPCs dried by HSD and FIR showed strong antibacterial activity against pathogenic bacteria and are more useful drying methods than that of the classic FD method in CPCs utilization.
