A singular Intervention: Implementation of the Neutropenic Infection-Prevention Bunch along with Review Device in a Oncology Unit.
We estimated associations between ambient air pollution, home environment and asthma as well as rhinitis among adults across China. A total of 40,279 young adults from eight Chinese cities participated in a questionnaire survey (participation rate 75%). There were questions on health and home environment. Information on city level gross domestic product (GDP) per capita, ambient temperature and PM10 and NO2 were collected from registers. Two-level logistic regression models were used to study health associations. Totally 1.6% reported asthma and 6.6% reported allergic rhinitis (AR). Higher temperature was associated with more asthma but less AR. Higher GDP was associated with less asthma but more AR. Higher degree of urbanization, higher level of NO2 and living near heavily trafficked road were risk factors for asthma and AR. Participants in older buildings reported more asthma. Redecoration and buying new furniture were related to more asthma and AR (OR = 1.15-1.91). Using natural gas (OR = 1.34) and biomass (OR = 1.35) for cooking were risk factors for AR. Burning mosquito coils and incense increased the risk of asthma and AR. selleck products Cat keeping (OR = 2.88), dog keeping (OR = 2.04), cockroaches (OR = 1.54) and rats or mice (OR = 1.46) were associated with asthma. Cockroaches increased the risk of AR (OR = 1.22). Air humidifier and air cleaner were linked to asthma and AR. Frequent cleaning and exposing bedding to sunshine were protective. In conclusion, urbanization, NO2 and traffic exhaust can increase the risk of adult asthma and AR. Higher ambient temperature was related to more asthma but less AR. Indoor animals such as cats, dogs, rats/mice and presence of cockroaches were associated with asthma or AR. Indoor chemical sources such as redecoration and new furniture were other risk factors. Cooking with natural gas or biomass and burning mosquito coils and incense were associated with asthma or AR. Frequent cleaning and exposing bedding to sunshine were protective.Freshwater lake ecosystem is a reservior of valuable microbial diversity. It needs to be explored for addressing key environmental issues like petroleum-hydrocarbon contamination. In this work, the microbial communities (pre and post enriched with petroleum-hydrocarbons) from different layers of freshwater lake, i.e. surface water, sediments and deepwater, were explored through metagenomic and culture-dependent approaches. A total of 41 bacterial phyla were retrieved from pre-enriched samples, which were significantly reduced in enriched samples where Proteobacteria were dominant (87% to 100%) followed by Bacteroidetes (7.37%) and Verrucomicrobia (3.06%). The most dominant hydrocarbon-degrading genera were extensively verified as Pseudomonas (48.65%), Acinetobacter (45.38%), Stenotrophomonas (3.16%) and Brevundimonas (2.07%) in surface water (S1WCC); Acinetobacter (62.46%), Aeromonas (10.7%), Sphingobacterium (5.20%) and Pseudomonas (4.23%) in sediment (S2MCC); and Acinetobacter (46.57%), Pseudomonas (13.10%), Comamonas (12.93%), Flavobacterium (12.18%) and Enterobacter (9.62%) in deep water (S4WCC). Additionally, the maximum biodegradation of petroleum-hydrocarbons (i.e. used engine oil or UEO) was achieved by microbiome of S2MCC (67.60 ± 0.08%) followed by S4WCC (59.70 ± 0.12%), whereas only 36.80 ± 0.10% degradation was achieved by S1WCC microbiome. On the other hand, UEO degradation by cultivable biosurfactant-producing single cultures such as Pseudomonas sp. S2WE, Pseudomonas sp. S2WG, Pseudomonas sp. S2MS, Ochrobactrum sp. S1MM and Bacillus nealsonii S2MT showed 31.10 ± 0.08% to 40.50 ± 0.11% biodegradation. Comparatively, the biodegradation efficiency was found higher (i.e. 42.20 ± 0.12% to 56.10 ± 0.12%) in each consortia comprising of two, three, four, and five bacterial cultures. Conclusively, the isolated culturable biosurfactants-producing bacterial consortium of freshwater lake demonstrated >80% contribution in the total petroleum-hydrocarbons degradation by the natural microbiome of the ecosystem.Ammonium removal in wastewater treatment plants requires a large number of energy input, such as aeration and the addition of organics. Alternative, more economical technologies for nitrogen removal from wastewater are required. This study comprehensively investigated the feasible of microbial electricity coupled with Fe(III) reduction promoting the anaerobic ammonium removal. It was found that electrostimulation coupled with Fe(III) reduction (bioelectrochemical systems-Fe(III) (BES-Fe(III)) reactor) enhanced the anaerobic ammonium removal by 50.38% and 38.8% compared with the BES reactor and Fe(III) reactor, respectively. The ammonium removal rate reached the highest value of 80.62 ± 0.26 g N m-3·d-1 in the Fe(III)-BES reactor comparable to conventional wastewater treatment plants (WWWTPs). The improvement of ammonium removal might be the synergistic effect of BES and Feammox process on reaction process and microorganisms. Firstly, the addition of Fe2O3 could improve the electrochemical characteristics by enriching iron-reducing bacterial (FeRB). Secondly, the improved ammonium removal could be due to nitrite generated from Feammox process driving the anodic ammonium oxidation. Additionally, the ammonium removal improvement might be the effect of BES on the Fe2+ leaching so as to accelerate the Fe (II)/Fe(III) cycle. In agreement, higher abundance of FeRB and iron-oxidizing bacteria was detected in the Fe(III)-BES reactor. This study provides a lower energy consumption and operational cost technology compared with the conventional partial nitrification/denitrification, which was more than 800 times less than for the conventional wastewater treatment.Addition of carbon-based byproducts in urban soil is gaining popularity as a plant growth stimulator, soil quality enhancer and fostering green land vegetation. A 60-day trial experiment was carried out for investigating the impacts of sugarcane, neem and bamboo mixed biochar and polyvinyl chloride (PVC), polyethylene (PE) and polyethylene terephthalate (PET) mixed plastic char (1100, 2100 and 4100 char soil ratio) on physico-chemical properties of soil and growth of Dendrocalamus strictus saplings. It was found that available phosphorus increased from 412.16 to 586.88 kg h-1 which could be attributed to reduced metal ion activity due to increase in the soil pH (7.75-7.81) and CEC (98.07-131.04 mEq 100 g-1). The application of both the char enhanced the quality of soil and thereby helped in achieving higher crop yields. Both biochar and plastic char increased the soil pH, total organic carbon, available phosphorus and nitrogen in the soil. Additionally, the results showed an entirely positive influence of the chars on plant height thereby making it more suitable for the improvement of agricultural system and reducing the dependency on market-based fertilizers.
