RESUMO

PURPOSE: In this prospective observational study, we aimed to investigate the role of the maximum compressed (MC) and uncompressed (UC) thickness of the quadriceps femoris muscle (QFMT) measured by ultrasonography (USG) in the detection of nutritional risk in intensive care patients (ICPs) with different volume status. METHODS: 55 patients were included. Right, left, and total ucQFMT and mcQFMT measurements were obtained by a standard USG device within the first 48 hours after ICU admission. Clinical examination and the USG device were used to determine the volume status of the patients. SOFA, APACHE II, modified NUTRIC scores, and demographic data were collected. RESULTS: There was a significant difference between the nutritional risk of patients in terms of left, right, and total mcQFMT measurements (p=0.025, p=0.039; p=0.028, respectively), mechanical ventilation requirement (p=0.014), presence of infection (p=0.019), and sepsis (p=0.006). There was no significant difference between different volume statuses in terms of mcQFMT measurements. In the multi-variance analysis, mcQFMT measurements were found to be independently associated with high nutritional risk (p=0.019, Exp(B)=0.256, 95%CI=0.082-0.800 for modified NUTRIC score ≥ 5), and higher nutritional risk (p=0.009, Exp(B)=0.144, 95%CI=0.033-0.620 for modified NUTRIC score ≥ 6). a Total mcQFMT value below 1.36 cm was a predictor for higher nutritional risk with 79% sensitivity and 70% specificity (AUC=0.749, p=0.002, likelihood ratio=2.04). CONCLUSION: Ultrasonographic measurement of total mcQFMT can be used as a novel nutritional risk assessment parameter in medical ICPs with different volume statuses. Thus, patients who could benefit from aggressive nutritional therapy can be easily identified in these patient groups.

RESUMO

OBJECTIVES: The purpose of this study was to analyze the effects of soybean extracts obtained using different extraction methods on the skin of female rats. METHOD: A total of 64 female Sprague-Dawley rats were divided into 8 equal groups. Various extracts were administered to the female rats by oral gavage for one month. The groups comprised carboxymethyl cellulose-free control, carboxymethyl cellulose-plus control, 100-mg/kg n-hexane extract, 200-mg/kg n-hexane extract, 100-mg/kg ethyl acetate extract, 200-mg/kg ethyl acetate extract, 100-mg/kg ethanol extract and 200-mg/kg ethanol extract groups. The thickness of the collagen layer and the number of estrogen receptor-positive cells were evaluated. RESULTS: All the extract-treated groups showed a statistically significant decrease in the number of estrogen receptor-positive cells compared with the control groups. Regarding the thickness of the collagen layer, only the 200-mg/kg ethyl acetate extract-treated group showed a significant increase compared with the control groups (p<0.05). CONCLUSIONS: Our data suggest that oral intake of three different total soybean extracts might have positive estrogenic effects on the skin and that only a high-dose ethyl acetate extract can increase the expression of collagen, which may prove to be beneficial for postmenopausal facial skin.
