In this study, magnetic ion exchange (MIEX) resin was evaluated to remove six carboxylic and three sulfonic PFAS at environmentally relevant concentrations (∼300 ng/L) in groundwater with low organic content and aromaticity (0.78 mg/L of dissolved organic carbon, DOC and 0.96 L mg-1m-1 of specific UV absorbance, SUVA). In order to evaluate PFAS adsorption, the apparent equilibrium constant for PFAS adsorption in a dilute system was derived as an indicator of the adsorption capacity of MIEX. In adsorption of PFAS, hydrophobic interactions induced by difluoromethylene and trifluoromethyl groups are known to be effective. However, the hydrophobic and charge interactions caused by such functional groups are not easily differentiable from each other since both are additive with respect to the chain length. In this study, the total negative atomic charge [∑Qi(-)] was calculated using density functional theory (DFT) calculation and correlated with the apparent equilibrium constants. The negative atomic charge showed better correlation than the hydrophobicity (log Dow at pH 7) of PFAS, suggesting that the charge interaction would be a more plausible role of fluorinated moieties for adsorption in the MIEX process than the hydrophobic interaction. This was also bolstered by the similar adsorption kinetics and equilibrium of PFOS (log Dow = 3.05) and its less hydrophobic isomer (log Dow = 2.79), but with almost identical total negative atomic charge (8.05 and 8.06 of ∑Qi(-), respectively). The regeneration efficiency of MIEX was also assessed. Almost complete restoration of PFAS adsorption capacity was achieved after 30 min of a regeneration process with a 10% w/w NaCl solution as a regenerant. The efficient regeneration was attributed to the effective desorption of dissolved organic matter that occupied sorptive sites predominantly.Objectives Clinically accessible body composition assessment is required to identify fat-free mass (FFM) depletion, which is common in inflammatory bowel disease (IBD) and poorly correlated with body mass index (BMI). The aim of this study was to compare FFM assessed using bioimpedance spectroscopy (BIS) and multifrequency bioelectrical impedance analysis (MFBIA) with dual energy x-ray absorptiometry (DXA) in adult outpatients with IBD. Methods FFM was measured using DXA, BIS, and MFBIA in 40 outpatients with IBD. Paired t tests, Lin and Pearson's correlations, and limits of agreement (LOA) analysis were used to compare FFMDXA with FFMBIS and FFMMFBIA. Results Participants (26 men, 24 with Crohn's disease) had a median (IQR) age 39 y (32-50 y) and median (IQR) BMI 24.2 kg/m2 (21.9-26.4 kg/m2). Mean FFMDXA was 51.6 ± 12 kg. FFMBIS was highly correlated with FFMDXA (rp = 0.97; P less then 0.001); however, BIS significantly overestimated FFM compared with DXA by a mean 3.4 ± 2.6 kg (P less then 0.001) and showed wide 95% LOA (-1.7 to 8.4 kg). FFMBIS estimations improved when FFM was adjusted for by BMI using Moissl's predictive algorithm, reducing mean bias to 0.1 ± 2 kg (P = 0.858; 95% LOA -3.9 to 4 kg). The bias between FFMMFBIA and FFMDXA was 1.3 ± 2 kg (P = 0.002) with 95% LOA -2.6 to 5 kg (n = 28). Conclusion Unadjusted BIS overestimated FFM in IBD outpatients compared with DXA with poor agreement at an individual level. this website Adjusting for BMI ameliorated the overestimation. It is suggested for the estimation of FFM in outpatients with IBD that MFBIA or the Moissl algorithm with BIS be used if DXA is unavailable.Objectives The purpose of this study was to evaluate the overall diet quality of an Italian population through the use of the Mediterranean Diet Serving Score (MDSS) and its relation to clinical and biochemical nutritional markers. Methods The study was conducted on healthy participants ages 18 to 86 y living in central Italy. Adherence to the Mediterranean food pattern was evaluated by a semiquantitative food frequency, using the MDSS. Anthropometric measurements and biochemical analyses of nutritional interest were performed according to the standardized procedure. Results The sample included a total of 349 participants (121 men and 228 women) with an average age of 54 ± 15 y and a body mass index of 27.4 ± 4.8 kg/m2, underlining an overweight status in both men and women. The mean educational level was medium-high in both sexes, whereas the occupation level was higher in women than in men (P = 0.001). The mean MDSS score was 14.4 ± 4.1 out of a total of 24 points. The adherence was higher in women (score 14.7 ± 3.9) than men (score 13.9 ± 4.4), although there were no significant differences (P = 0.25). No statistical differences in MDSS were found in relation to body mass index and educational level, whereas a higher MDSS score was observed in the older age group (P less then 0.05). A positive correlation among MDSS, high-density lipoprotein cholesterol, and vitamin C has been found (P less then 0.05), whereas there was a negative correlation with uric acid and triacylglycerols (P less then 0.05). A logistic regression analysis highlighted smoking habit as the only predictive factor for a high adherence to MDSS (P less then 0.05). Conclusions MDSS has a low adherence to the Mediterranean diet, particularly in the youngest age group and smokers. The index shows a correlation with some parameters of nutritional interest and further larger cohorts studies are needed to confirm our findings.Purpose To determine the maximum tolerated dose (MTD) of stereotactic ablative radiotherapy (SABR) in combination with immunotherapy for the treatment of metastatic melanoma. The study also investigates the effects of timing and dosing of SABR on clinical efficacy. Methods Metastatic melanoma patients with at least two metastases received SABR to a single metastatic site. All patients had standard dose immunotherapy with anti-PD1 and/or anti-CTLA4 at the discretion of their treating clinician. Following a standard 3+3 design, patients were escalated through three SABR doses (10 Gy, 15 Gy and 20 Gy) delivered at three different time points (with Cycle 1, 2, or 3 of immunotherapy). Dose limiting toxicities (DLT) was defined as Grade 3 or higher toxicity within three months of first treatment and assessed by an independent data safety monitoring committee (IDSMC). Logistic or Cox regressions were used to assess the impact of SABR dose and timing on the progression-free (PFS) and overall survival (OS) of this cohort.
