Not, only that, our study also provided a reference for the remediation of MP-contaminated soil.This study employed high-throughput quantitative polymerase chain reaction to evaluate the effects of specific co-substrate and additive on the fitness of antibiotic resistome during swine manure composting. The results showed that corncob particle as a co-substrate significantly reduced the relative abundances of antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) simultaneously. The diversity of ARGs was also reduced more effectively by corncob addition. Brick granule as an additive reduced the concentrations of bioavailable Cu and Zn. However, the relative abundances of ARGs and MGEs were not reduced by the addition of brick granule subsequently. Redundancy analysis indicated a negative effect of the C content and positive effects of class I integrase gene (intI) and bioavailable metals on the variation of the relative abundance of ARGs (p less then 0.01). The Procrustes test showed a higher goodness-of-fit between the relative abundance of ARGs and 16S rRNA genes (r = 0.8166; p less then 0.0001). Our results suggests that the effect of corncob particle on the relative abundance of ARGs was achieved by driving the changes in physicochemical properties and microbial communities. This study confirmed the hypothesis of fitness cost and demonstrated the contribution of extra C source to ARG attenuation during composting.Sandy beaches are key economic assets worldwide, however, recreational activities are an important source of disturbance in these ecosystems. Intensive human use of beaches has a negative effect on benthic communities as it alters species abundance, diversity, and/or distribution. Here, we report the impacts of recreational activities (trampling and vehicles) on meiobenthic communities and nematode assemblages on Amazonian sandy beaches for the first time. For this purpose, samples were carried out in four consecutive months encompassing a period of high visitation peak (one month Before Vacation, During Vacation, and two months After Vacation) on three contrasting beaches regarding disturbances (Urban Atalaia; Intermediary Farol-Velho; and Protected Corvinas) at seven equidistant sampling stations (50 m apart) from the high tide water mark to the swash zone. At each sampling station, three biological samples and sediments samples were collected haphazardly. Also, in each station, the sediment compaction was determined using a manual penetrometer. Overall, physical sediment variables (grain size, sorting) were constant over time in all beaches, whereas differences in intensity of recreational activities and sediment compaction were found between beaches and months. Sediment compaction was considered the most important factor for the differences observed in meiofauna community structure in the study areas, and it was related to intensity of recreational activities. Variations in density and changes in richness between periods were observed in Atalaia and Farol-Velho beaches. On the other hand, Corvinas beach remained the same throughout the study. In the first month after vacation, density and richness were similar to those in the period before vacation, thus indicating that the beaches had recovered in one month. Furthermore, vulnerabilities of Tardigrada and Copepoda, as well as of the Nematoda genera Daptonema, and Chromadorita, indicate that they might be potential indicators of recreational activities.
In the last two decades, India's central and many state governments launched several public health programs with the goal of improving maternal and child health outcomes. Many individual studies assessed the impact of these programs; however, they focused on select health programs and few specific outcomes.

This paper summarizes the literature, published during 2000-2019, investigating the impacts of public health programs on both the uptake of maternal and child health services and the related-health outcomes in India. We followed PRISMA guidelines of systematic review, and carried out a narrative synthesis of the study findings.

We found 66 relevant studies covering 11 health programs across India. Most studies had applied non-experimental study designs (n=50), with few applying experimental (n=1) and quasi-experimental (n=15) designs. Most studies (n=64) assessed the impact on the intermediate outcomes of the uptake of various health services rather on the long-term outcomes of improvement in health.on (intent-to-treat effect). Furthermore, there was dearth of research on the impacts of the state-level programs. Future research need to assess the impact of the programs on health outcomes, and on quality adjusted measures of maternal and child health services and its continuum of care.Despite its increasing use, little is known about the effect of electronic cigarette. This study estimates the impact of the use of electronic cigarettes on tobacco smoking and health among tobacco smokers, using French panel data derived from the Health, Health Care, and Insurance Survey for 2010-2014. We use a difference-in-differences propensity score matching approach to identify the effect of electronic cigarette use on a sample of 982 smokers. We show that the use of electronic cigarettes increases the probability of quitting smoking and reduces the number of regular cigarettes smoked per day. However, we also find evidence that electronic cigarette users have a higher probability of reporting poor health status and suffering from a chronic disease compared with those who only smoke regular cigarettes. Overall, our results do not support the use of electronic cigarettes for tobacco smokers.
This review examines the evidence regarding treatment of central vein obstruction (CVO) in the setting of ipsilateral haemodialysis access. The aim is to identify whether long-term venous patency following central vein stenting is superior compared to balloon venoplasty. To date, there are no evidence-based guidelines to direct management of CVO in the setting of ipsilateral haemodialysis access.

An extensive systematic database search was performed using Medline, Embase and Cochrane Databases to identify all articles published since January 2000 to November 2019 comparing the management of CVO with venoplasty and/or stenting in the setting of ipsilateral haemodialysis access fistulae/grafts.

655 patients with 456 stenoses and 208 occlusions were treated. LY2584702 288 underwent venoplasty and 345 underwent stenting. 22 patients failed intervention due to inability to traverse the occlusion. The most affected vein was the brachiocephalic vein. A superior primary patency is noted in those treated with stenting compared to venoplasty in the first two years.
