Most late-eaters reported to eat breakfast regularly, suggesting a long eating window and short fasting period in this group. BMI and HbA1c did not differ between late-eaters and the reference group. Eating late in the evening or during the night was prevalent among individuals with type 2 diabetes across BMI and HbA1c levels. Whether restriction of food intake during evening and night-time can induce weight loss and improve glycemic control in individuals with type 2 diabetes needs testing in randomized controlled trials.Bariatric surgery is a metabolic surgery known to be an efficient treatment for weight loss, with adequate long-term maintenance. Interestingly, some studies have reported a reduction in branched chained amino acids (BCAAs) after bariatric surgery, which putatively contributes to post-surgical metabolic improvement. The current systematic review and meta-analysis investigated the effect of bariatric surgery on the level of BCAAs. PubMed, SCOPUS, EMBASE, and Web of Science databases were searched from their inception to July 2019. All clinical trials which investigated the effect of bariatric surgery on the levels of valine, leucine, and isoleucine, for more than one week, were included. Nine studies (11 effect sizes) were analyzed via meta-analytical techniques using random-effects models. The pooled data suggested that bariatric surgery significantly reduced the valine (standardized mean difference [SMD] -1.89, 95% confidence interval [CI] -2.79, -0.99, I2 = 90.9%), leucine (SMD -0.96, 95% CI -1.48, -0.44, I2 = 72.4%), and isoleucine (SMD -0.58, 95% CI -0.84, -0.31, I2 = 66.3%) levels after surgery compared with before the surgery. Overall, bariatric surgery significantly reduced the levels of valine, leucine, and isoleucine compared with before the surgery. Further large-scale and homogenous trials are needed to better discern the generalizability of our findings.The uncertainties on the occurrence, fate and hazard of Contaminants of Emerging Concern (CECs) increasingly challenge drinking water (DW) utilities whether additional measures should be taken to reduce the health risk. This has led to the development and evaluation of risk-based approaches by the scientific community. DW guideline values are commonly derived based on deterministic chemical risk assessment (CRA). Here, we propose a new probabilistic procedure, that is a quantitative chemical risk assessment (QCRA), to assess potential health risk related to the occurrence of CECs in DW. The QCRA includes uncertainties in risk calculation in both exposure and hazard assessments. To quantify the health risk in terms of the benchmark quotient probabilistic distribution, the QCRA estimates the probabilistic distribution of CECs concentration in DW based on their concentration in source water and simulating the breakthrough curves of a granular activated carbon (GAC) treatment process. The model inputs and output uncertainties were evaluated by sensitivity and uncertainty analyses for each step of the risk assessment to identify the most relevant factors affecting risk estimation. Dominant factors resulted to be the concentration of CECs in water sources, GAC isotherm parameters and toxicological data. To stress the potential of this new QCRA approach, several case studies are considered with focus on bisphenol A as an example CEC and various GAC management options. QCRA quantifies the probabilistic risk, providing more insight compared to CRA. QCRA proved to be more effective in supporting the intervention prioritization for treatment optimization to pursue health risk minimization.We systemically investigated the transformation behavior of 2,4-dichlorophenol (24-DCP) in seven different reaction systems including KMnO4, heat/PS, O3, UV, Fenton, NaClO and K2FeO4 treatment. The results revealed that complete removal of 24-DCP could be reached in minutes, especially for Fe(VI), KMnO4, NaClO, Fenton and O3 system. RG108 inhibitor A total of 41 products were identified by LC-MS, and 10 of them were validated using commercial and self-synthesized standards. Hydroxyl substitution and coupling reactions were commonly observed in the studied systems. Meanwhile, extra routes such as sulfate substitution, (de)chlorination and direct oxidation were also involved for certain oxidation methods. Comparisons showed that a high degree of chlorination (>90%) occurred for NaClO system, while coupling products accounted for ~45% of the removed 24-DCP under PS oxidation. Moreover, low mineralization degree together with high aquatic toxicity was attributed to the occurrence of coupling reaction, which was possibly related to the redox potential of the main oxidative species. Considering the low abundance of coupling products and the gentle reaction condition, UV irradiation is a better option for 24-DCP removal in water and wastewaters. These findings can deepen our understanding on the transformation process of 24-DCP and provide some useful information for the environmental elimination of substituted phenols.Uncertainty in urban drainage modelling studies presents challenges to decision makers with limited investment resources attempting to achieve regulatory compliance for intermittent discharges from Combined Sewer Overflows. This paper presents the development of a new decision-making approach to address two key challenges encountered when attempting to manage sewer overflows, these are (i) the implications of different risk preferences of individuals for investment decisions; and (ii) how to utilize information on uncertainties in system performance predictions due to input or parameter uncertainty while comparing decision alternatives. The developed decision-making approach uses a multi-objective decision formulation to analyse the trade-off between investment and predicted system performance under uncertainty while accounting for risk preferences of the individual decision maker. The proposed uncertainty based decision-making approach is able to incorporate any threshold-based regulatory criteria for intermittent sewer overflows and is illustrated using a case study catchment in Luxembourg. The results from this case study highlight the significant impact of individuals' risk preferences on the level of investment recommended to comply with threshold-based regulatory criteria. It was demonstrated that differing levels of risk-averseness can result in a substantial increase in investment cost for solutions that are regulatory compliant. This paper demonstrates the need for water companies to rigorously define a corporate risk preference strategy to ensure consistent investment decisions across their operations; otherwise, individual preferences may cause significant over-investment to meet the same regulatory goals.
