OBJECTIVES: Antibiotic stewardship is an integral aspect of hospital care, limiting the potential for resistance while working to minimize waste. A similar system is needed in oncology, given the rapid proliferation of new therapies and the challenges of navigating a complicated reimbursement environment. A "cancer therapy stewardship program" has never been described in the literature. Here, we detail our efforts to design and implement such a program and share lessons learned to inform future projects...

This study examined the potential of Escherichia coli (E. coli) and Ascaris lumbricoides (A. lumbricoides) eggs inactivation in faecal matter coming from urine diverting dehydrating toilets (UDDT-F) by applying high concentrations of volatile fatty acids (VFAs) during anaerobic stabilization. The impact of individual VFAs on E. coli and A. lumbricoides eggs inactivation in UDDT-F was assessed by applying various concentrations of store-bought acetate, propionate and butyrate. High VFA concentrations were also obtained by performing co-digestion of UDDT-F with organic market waste (OMW) using various mixing ratios...

Management of the ever-increasing generated solid waste had been a difficulty for state governments in Nigeria. The high costs connected to this waste management which had encumbered the state budget, ignorance or lack of understanding of resourceful waste management and insensitivity to environmental concerns may have led to partial neglect of this sector. This research paper is aimed at evaluating the rehabilitation potential and the risk level of Igbatoro dumpsite, an Ondo state-managed waste dumpsite which predominantly receives the waste of Akure and its environs...

Many high-density cities struggle to find space for disposing municipal solid waste. Hong Kong is one of these cities, seeking to scale up waste recovery efforts as an alternative to disposal. However, territory-wide recovery initiatives do not account for socio-economic variations across place, leading to mixed outcomes among diverse communities. This study aims to investigate socio-economic effects on recycling behavior in a sample of subsidized rental housing estates. It constitutes an improvement from previous studies by using the entire estate as a unit of analysis and analyzing actual recycling outcomes, which have received limited attention from researchers...

Given the increasing vulnerability of communities to the negative impacts of untreated wastewater, resource recovery (RR) systems provide a paradigm shift away from a traditional approach of waste separation and treatment towards a productive recovery of water, energy and nutrients. The aim of this research is to understand the relationships between factors that influence the adoption and sustainability of wastewater-based RR systems to inform technology implementation strategies. The study presents a theory-informed, community-influenced system dynamics (SD) model to provide decision-makers with an adaptable tool that simulates system-level responses to the strategies that are developed for the coastal town of Placencia, Belize...

Food waste is a worldwide problem due to its effects on carbon emission, water pollution, and arable lands. Previous studies of food waste generation and reduction focus on demographic, psychological, and situational factors, whereas the effects of culture in different countries have been ignored. This paper investigates the influence of Confucian culture on behaviors that waste food, considering additional factors of face saving and group conformity. We used an integrated behavioral intention model combining the TPB model and Lee's modified Fishbein model...

This study focuses on the mechanical recycling of polymeric waste that is produced in considerable amount from the cable industry. Every year large amounts of cables become waste; wires recycling has traditionally focused on metal recovery, while the polymer cover has just been considered as a residue, being landfilled or incinerated. Nowadays, increasingly restrictive regulations and concern about environment make necessary to reduce landfilling as much as possible. Main novelty of the study is that the material used in the research is a post-consumer material and the entire residual material is used, without a previous purification, in contrast with similar studies...

Solid keratin-rich waste management is one of essential research area in nowadays. Conventional chemical and high thermal keratin waste decomposition methods are fully explored and not enough effective for future biotechnology perspectives. However, traditional keratin-rich waste decomposition methods could be replaced by environmentally-friendly and economical microbial keratin waste biodegradation methods without energy wastage and essential amino acids and nutrition elements loss. In this study BPKer and BAKer keratinolytic peptidases from Bacillus sp...

The solubility of iron (Fe), as an important micronutrient for plant growth, is not high in the calcareous soils, and hence efficient methods must be used to increase its availability for plant use. Accordingly, a two-year research work was conducted to investigate the effects of composted municipal solid wastes (MSW) on Fe accumulation and fractionation in a calcareous soil. Treatments including MSW levels at (0 (control), 15 (MSW1), 30 (MSW2) and 60 (MSW3) t ha-1 dry weight) and usage time (yearly (T1) or biyearly usage (T2)) were tested in a factorial experiment on the basis of a completely randomized block design with three replications...

The damselfish Chromis chromis is typically the most abundant fish species in the rocky littoral environment of the Mediterranean Sea, where it feeds in huge shoals on incoming zooplankton and rests near the seabed each night. Research has shown that large populations of C. chromis play a fundamental role by transferring carbon, nitrogen and phosphorus directly from the pelagic system to the littoral in the form of solid and liquid wastes and therefore that this species acts as a vital conduit for nutrients...

The purpose of this research was to improve microbial fuel cell (MFC) performance - treating landfill-derived waste liquor - by applying effluents of various biogas fermenters as inocula. It turned out that the differences of initial microbial community profiles notably influenced the efficiency of MFCs. In fact, the adaptation time (during 3 weeks of operation) has varied significantly, depending on the source of inoculum and accordingly, the obtainable cumulative energy yields were also greatly affected (65% enhancement in case of municipal wastewater sludge inoculum compared to sugar factory waste sludge inoculum)...

The inadequate management of fish processing waste or by-products is one of the major problems that fish industry has to face nowadays. The mismanagement of this raw material leads to economic loss and environmental problems. The demand for the use of these by-products has led to the development of several processes in order to recover biomolecules from fish by-products. An efficient way to add value to fish waste protein is protein hydrolysis. Protein hydrolysates improve the functional properties and allow the release of peptides of different sizes with several bioactivities such as antioxidant, antimicrobial, antihypertensive, anti-inflammatory, or antihyperglycemic among others...

Providing food to wildlife during periods when natural food is limited results in aggregations that may facilitate disease transmission. This is exemplified in western Wyoming where institutional feeding over the past century has aimed to mitigate wildlife-livestock conflict and minimize winter mortality of elk ( Cervus canadensis ). Here we review research across 23 winter feedgrounds where the most studied disease is brucellosis, caused by the bacterium Brucella abortus Traditional veterinary practices (vaccination, test-and-slaughter) have thus far been unable to control this disease in elk, which can spill over to cattle...

Evidence from a well-designed randomized controlled trial (RCT) is generally considered to be the gold standard that can inform clinical practice and guide decision-making. However, several deficiencies in the reporting of RCTs have frequently been identified, including incomplete, selective, and biased or inconsistent reporting. Such suboptimal reporting may lead to irreproducible results, substantial waste of resources, impaired study validity, erosion of public trust in science, and a high risk of research misconduct...

The concept of self-healing asphalt mixtures by bitumen temperature increase has been used by researchers to create an asphalt mixture with crack-healing properties by microwave or induction heating. Metals, normally steel wool fibers (SWF), are added to asphalt mixtures prepared with virgin materials to absorb and conduct thermal energy. Metal shavings, a waste material from the metal industry, could be used to replace SWF. In addition, reclaimed asphalt pavement (RAP) could be added to these mixtures to make a more sustainable road material...

The late 1970s was the onset of literature about the first research outputs on alternatives to create added-value to agro-food by-products focused on the reduction of the dependency on raw materials and, simultaneously, helping to reduce the environmental impacts of the agricultural activities. This trend, increased over the years and during the last decade, has been boosted by the growing concern of the socio-economic impact of wastes from agro-food activities; however, with little success of the proposed applications...
