Pulmonary rehabilitation is essential in post-COVID subjects, reporting respiratory impairment after the discharge from the hospital. Because the number of patients with respiratory outcomes is high and there are few facilities available, we wonder if a spa setting could represent a valid out-of-hospital alternative. We aim to explore recent evidence related to respiratory rehabilitation in the spa environment to understand if it can represent an appropriate setting for respiratory rehabilitation interventions in post-COVID subjects. Studies were found by screening PubMed, MEDLINE, and Google Scholar databases from 2011 up to February 2021. Studies were eligible if they were reviews, randomized controlled trials (RCTs), or clinical trials, investigating respiratory interventions in the spa environment. Recent evidence has shown that inhalations and mineral-rich water immersions are effective in fighting and preventing multiple chronic respiratory tract diseases. Therefore, these treatments could also be applied to post-COVID patients with medium long-term respiratory outcomes.Animal studies suggested that exposure to ethylene oxide (EO) might induce hepatic lipid peroxidation and inflammatory lesions in various organs. However, the association between EO exposure and diabetes risk in humans is unknown. This study aimed to examine the association of EO exposure with the prevalence of diabetes mellitus in a general population of US adults. This study consisted of 3448 participants aged 20 years and older from the National Health and Nutrition Examination Survey (NHANES) 2013-2014 cycle and 2015-2016 cycle. Circulating levels of EO biomarker (hemoglobin adducts of EO (HbEO)) was measured by using high-performance liquid chromatography coupled with tandem mass spectrometry. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using multivariate logistic regression. selleck products The weighted median level of HbEO was 29.9 (95% CI 21.8, 56.0) pmol/g Hb. Elevated levels of HbEO were associated with higher HbA1c and lower high-density lipoprotein cholesterol (both Ptrend less then 0.01). After multivariate adjustment including demographics, lifestyle factors, and body mass index (BMI), higher HbEO levels were significantly associated with an increased prevalence of diabetes mellitus. The OR (95% CI) of diabetes across increasing quartiles of HbEO was 1.00 (reference), 1.45 (1.08, 1.96), 1.76 (1.31, 2.36), and 1.77 (1.22, 2.57), respectively (Ptrend less then 0.001). Similar results were observed when analyses were stratified by smoking status, age, sex, race/ethnicity, and BMI. In a nationally representative sample of US adults, higher levels of HbEO were significantly associated with an increased prevalence of diabetes mellitus. Further prospective studies are needed to confirm these findings.This study investigated the effectiveness of bio-augmenting aerobic cell culture to mitigate ammonia and hydrogen sulfide emission in sewage sludge composting amended with reed straw (with the weight ratio of 10.3-0.4). During the 20-day aerated lab-scale composting, adding 200-mL culture (56.80 NTU) reduced ammonia and hydrogen sulfide emissions by 38.00% and 54.32%, and conserved total nitrogen and sulfate by 39.42% and 70.75%, respectively. Organic matters degradation was quick started 1 day ahead. Comparing to the control, nitrate content increased 38.75% at the end of the compost. Bioaugmentation evened the distributions of bacterial communities in the thermophilic phase. The shift was mainly due to 22.97% of relative abundance of Proteobacteria depressed and 157.16% of Bacteroidetes increased, which were beneficial for nitrogen conservation and glycan breakdown, respectively. In summary, the results demonstrated that bioaugmentation addition could be an effective strategy for enhanced sludge composting.Severe haze frequently hits the North China Plain (NCP), especially in winter during recent years. Meteorological factors affect aerosol formation and its optical properties, and accurate meteorological fields are imperative for accurate aerosol simulations. The impacts of Global Positioning System Zenith Total Delay (GPS-ZTD) data assimilation on meteorology and aerosol simulations were evaluated in this study using the WRF-CMAQ (the Weather Research and Forecasting model and Community Multiscale Air Quality) modelling system over the NCP during 01-31 December 2019. After bias correction, GSP-ZTD data were assimilated into the WRF model using the 3DVAR technique. Two sensitivity tests (CTR and ZTD) were conducted. The WRF model had generally acceptable performance for surface and upper air meteorological variables, PM2.5 and visibility. From the aspect of BIAS, STDE, RMSE, and R, the assimilation of ZTD data improved the underestimation of ground relative humidity (RH). The improvement was more pronounced inecific stations can be great. The improvement of PM2.5 troughs was in the range of 1-5 μg/m3, while the overestimation of PM2.5 peaks was reduced by few up to dozens μg/m3. This will contribute to the extreme value prediction during pollution episode.The TransMilenio (TM) is a transport system. Twenty-year-old TM is a fast, highly efficient, and self-sufficient mode of passenger transport. This work aims to evaluate the effects of changing current TM diesel buses by electricity-powered buses (battery, wire-based), on the PM2.5 concentrations at surface level. Emissions calculations considering combustions and resuspension of TM and Non-TM were performed. A CFD model was implemented to estimate current PM2.5 concentrations at the roadside level, and the CFD results were validated using the statistic parameters MB, RMSE, r, and IOA. Results from the emission calculations indicate that TM buses (30-50%) are one of the main sources of primary PM2.5 in all the considered urban sites in this study. Non-exhaust emissions from most vehicle categories were also identified as an important source of primary PM2.5 (40% of total emissions). The CFD model reproduced closely the trends and levels of PM2.5 concentrations measured at the roadside level in all the locations.
