RESUMEN

INTRODUCTION: Exercise is vital to health and well-being after a cancer diagnosis yet is poorly integrated in cancer care. Knowledge mobilization (KM) is essential to enhance exercise opportunities. We aimed to (1) develop and refine a list of highly important exercise oncology research and KM themes and (2) establish the relative importance of the themes for supporting the implementation of exercise as a standard of care for people living with and beyond cancer. METHODS: Informed by the Co-Produced Pathway to Impact KM framework, a modified Delphi study approach was used to develop, rate, and rank exercise oncology research and KM themes through an international stakeholder workshop and a three-round iterative online survey. Open-ended stakeholder feedback from cancer survivors, healthcare practitioners (HCPs), qualified exercise professionals (QEPs), policy makers, and researchers was used to update themes between survey rounds. Themes were ranked from highest to lowest importance and agreement was examined across all stakeholders and within stakeholder groups. RESULTS: A total of 269 exercise oncology stakeholders from 13 countries participated in the study. Twelve final exercise oncology research and KM themes were produced. The final top ranked research themes were related to: (1) QEP integration into primary cancer care teams, (2) Exercise oncology education for HCPs, and (3) Accessibility of cancer exercise programs & support services. There was statistically significant agreement between stakeholders (p<0.001) and within stakeholder groups (p's≤0.02) on the general rankings of themes (i.e., some themes generally ranked higher and lower compared to others). Low Kendall's W statistics indicated variability related to the specific ranked order of the themes between stakeholders and within stakeholder groups. Moreover, there were key differences in the rankings for specific themes between policy makers and other stakeholder groups that highlight potentially important discordance in the research and KM priorities for policy makers that warrants further study. CONCLUSION: These findings can be used to guide initiatives and align stakeholders on priorities to support exercise implementation as a standard of cancer care. Additional research is needed to better understand the differences in the proposed research and KM priorities across stakeholders.

RESUMEN

BACKGROUND: Research funders in Canada and abroad have made substantial investments in supporting collaborative research approaches to generating and translating knowledge as it is believed to increase knowledge use. Canadian health research funders have advocated for the use of integrated knowledge translation (IKT) in health research, however, there is limited research around how IKT compares to other collaborative research approaches. Our objective was to better understand how IKT compares with engaged scholarship, Mode 2 research, co-production and participatory research by identifying the differences and similarities among them in order to provide conceptual clarity and reduce researcher and knowledge user confusion about these common approaches. METHODS: We employed a qualitative descriptive method using interview data to better understand experts' perspectives and experiences on collaborative research approaches. Participants' responses were analysed through thematic analysis to elicit core themes. The analysis was centred around the concept of IKT, as it is the most recent approach; IKT was then compared and contrasted with engaged scholarship, Mode 2 research, co-production and participatory research. As this was an iterative process, data triangulation and member-checking were conducted with participants to ensure accuracy of the emergent themes and analysis process. RESULTS: Differences were noted in the orientation (i.e. original purpose), historical roots (i.e. disciplinary origin) and partnership/engagement (i.e. role of partners etc.). Similarities among the approaches included (1) true partnerships rather than simple engagement, (2) focus on essential components and processes rather than labels, (3) collaborative research orientations rather than research methods, (4) core values and principles, and (5) extensive time and financial investment. Core values and principles among the approaches included co-creation, reciprocity, trust, fostering relationships, respect, co-learning, active participation, and shared decision-making in the generation and application of knowledge. All approaches require extensive time and financial investment to develop and maintain true partnerships. CONCLUSIONS: This qualitative study is the first to systematically synthesise experts' perspectives and experiences in a comparison of collaborative research approaches. This work contributes to developing a shared understanding of collaborative research approaches to facilitate conceptual clarity in use, reporting, indexing and communication among researchers, trainees, knowledge users and stakeholders to advance IKT and implementation science.

RESUMEN

BACKGROUND: Young people who seek mental health treatment often also seek the services of non-profit organizations to support their well-being. Wisdom2Action (W2A) is a Canadian knowledge mobilization network that focuses on improving the mental health and well-being of children and youth in challenging contexts by increasing the use of evaluation, evidence and engagement in the youth-serving sector. Since 2013, W2A has engaged youth advisors (YAs) to provide input to W2A's Board, lead their own projects and co-design W2A activities. OBJECTIVE: In fall 2017, the YAs, as well as adult Board members and W2A staff, collaborated in a participatory evaluation to better understand the experiences and impacts of youth engagement. This article describes insights derived through this process. DESIGN AND PARTICIPANTS: Board, YAs and staff members participated in a reflective approach to informing, analysing and sharing the findings from this process. Individual interviews and review of documents, as well as iterative cycles of group analysis and synthesis, were conducted. RESULTS: Both YAC members and W2A benefit from YAs' leadership and engagement. The YAs position themselves as members of the youth-serving sector, not merely recipients of its services; as such, their professional development aligns with the mandates of W2A and merits further investment, despite challenges in impact measurement. CONCLUSION: This article identifies challenges and facilitators of implementing an effective and sustainable youth advisory council model of engagement in the context of a pan-Canadian network. The mutual gains and areas of growth for youth, adults and the organization described can inform health services, as well as funders and advocates for youth well-being.

RESUMEN

During the last 50 years, the human activities have significantly altered the natural cycle of phosphate in this planet, causing phosphate to accumulate in the freshwater ecosystems of some countries to at least 75% greater than preindustrial levels, which indicates an urgent need to develop efficient phosphate treatment methods. Therefore, the current study investigates the removal of phosphate from river water using a new electrochemical cell (PBPR). This new cell utilises perforated baffle plates as a water mixer rather than magnetic stirrers that require power to work. This study investigates the influence of key operational parameters such as initial pH (ipH), current density (Ј), inter-electrode distance (ID), detention time (t) and initial phosphate concentration (IC) on the removal efficiency, and influence of the electrocoagulation process on the morphology of the surface of electrodes. Overall, the results showed that the new reactor was efficient enough to reduce the concentration of phosphate to the permissible limits. Additionally, SEM images showed that the Al anode became rough and nonuniform due to the production of aluminium hydroxides. The main advantages of the electrocoagulation technique are: •The EC method does not produce secondary pollutants as it does not required chemical additives, while other traditional treatment methods required either chemical or biological additives [[1], [2], [3], [4]].•It has a large treatment capacity and a relatively short treatment time in comparison with other treatment methods, such as the biological methods [1,[5], [6], [7]].•The EC method produces less sludge than traditional treatment traditional chemical and biological treatment methods [8,9]. EC technology, like any other treatment method, has some drawbacks that could limit its performance. For instance, it still has a clear deficiency in the variety of reactor design, and the electrodes should be periodically replaced as they dissolve into the solution due to the oxidation process [2,10].

RESUMEN

A new batch, flow column electrocoagulation reactor (FCER) that utilises a perforated plate flow column as a mixer has been used to remove fluoride from drinking water. A comprehensive study has been carried out to assess its performance. The efficiency of fluoride removal (R%) as a function of key operational parameters such as initial pH, detention time (t), current density (CD), inter-electrode distance (ID) and initial concentration (C0) has been examined and an empirical model has been developed. A scanning electron microscopy (SEM) investigation of the influence of the EC process on morphology of the surface of the aluminium electrodes, showed the erosion caused by aluminium loss. A preliminary estimation of the reactor's operating cost is suggested, allowing for the energy from recycling of hydrogen gas hydrogen gas produced amount. The results obtained showed that 98% of fluoride was removed within 25 min of electrolysis at pH of 6, ID of 5 mm, and CD of 2 mA/cm2. The general relationship between fluoride removal and operating parameters could be described by a linear model with R2 of 0.823. The contribution of the operating parameters to the suggested model followed the order: t > CD > C0 > ID > pH. The SEM images obtained showed that, after the EC process, the surface of the anodes, became non-uniform with a large number of irregularities due to the generation of aluminium hydroxides. It is suggested that these do not materially affect the performance. A provisional estimate of the operating cost was 0.379 US $/m3. Additionally, it has been found that 0.6 kW/m3 is potentially recoverable from the H2 gas.

RESUMEN

In this investigation, a new bench-scale electrocoagulation reactor (FCER) has been applied for drinking water denitrification. FCER utilises the concepts of flow column to mix and aerate the water. The water being treated flows through the perforated aluminium disks electrodes, thereby efficiently mixing and aerating the water. As a result, FCER reduces the need for external stirring and aerating devices, which until now have been widely used in the electrocoagulation reactors. Therefore, FCER could be a promising cost-effective alternative to the traditional lab-scale EC reactors. A comprehensive study has been commenced to investigate the performance of the new reactor. This includes the application of FCER to remove nitrate from drinking water. Estimation of the produced amount of H2 gas and the yieldable energy from it, an estimation of its preliminary operating cost, and a SEM (scanning electron microscope) investigation of the influence of the EC process on the morphology of the surface of electrodes. Additionally, an empirical model was developed to reproduce the nitrate removal performance of the FCER. The results obtained indicated that the FCER reduced the nitrate concentration from 100 to 15 mg/L (World Health Organization limitations for infants) after 55 min of electrolysing at initial pH of 7, GBE of 5 mm, CD of 2 mA/cm2, and at operating cost of 0.455 US $/m3. Additionally, it was found that FCER emits H2 gas enough to generate a power of 1.36 kW/m3. Statistically, the relationship between the operating parameters and nitrate removal could be modelled with R2 of 0.848. The obtained SEM images showed a large number dents on anode's surface due to the production of aluminium hydroxides.

RESUMEN

Stress, caused by exposure to microwaves (2.45 GHz) at constant temperature (37 ± 0.5°C), alters the growth profile of Pseudomonas aeruginosa PAO1. In the absence of microwave treatment a simple, highly reproducible growth curve was observed over 24 h or more. Microwave treatment caused no reduction in growth during the first 6 h, but at a later stage (>12 h) the growth was markedly different to the controls. Secondary growth, typical of the presence of persisters clearly became apparent, as judged by both the dissolved oxygen and the cell density profiles. These treated cells showed distinct morphological changes, but on regrowth these cells reverted to normal. The microwave induced persisters were subject to antibiotic challenge (tobramycin) and showed increased sensitivity when compared to the unstressed planktonic cells. This is in marked contrast to antibiotic induced persisters which show increased resistance. This provides evidence for both a nonthermal effect of microwaves and a previously undescribed route to a novel form of antibiotic susceptible persister cells. © 2016 American Institute of Chemical Engineers Biotechnol.

RESUMEN

The goal of this project was to remove iron from drinking water using a new electrocoagulation (EC) cell. In this research, a flow column has been employed in the designing of a new electrocoagulation reactor (FCER) to achieve the planned target. Where, the water being treated flows through the perforated disc electrodes, thereby effectively mixing and aerating the water being treated. As a result, the stirring and aerating devices that until now have been widely used in the electrocoagulation reactors are unnecessary. The obtained results indicated that FCER reduced the iron concentration from 20 to 0.3 mg/L within 20 min of electrolysis at initial pH of 6, inter-electrode distance (ID) of 5 mm, current density (CD) of 1.5 mA/cm2, and minimum operating cost of 0.22 US $/m3. Additionally, it was found that FCER produces H2 gas enough to generate energy of 10.14 kW/m3. Statistically, it was found that the relationship between iron removal and operating parameters could be modelled with R2 of 0.86, and the influence of operating parameters on iron removal followed the order: C0>t>CD>pH. Finally, the SEM (scanning electron microscopy) images showed a large number of irregularities on the surface of anode due to the generation of aluminium hydroxides.

RESUMEN

The food industry is keen to have new techniques that improve the safety and/or shelf life of food products without the use of preservatives. There is considerable interest in developing UV light and ozone (O3) treatments to enhance shelf life. A microwave radiation device that is a novel source of germicidal UV and O3 suitable for the food industry has been developed, which offers speed, cost and energy benefits over existing sources. With this system comes the need to monitor a number of conditions, primarily UV intensity and ozone gas concentrations. The effectiveness of intense UV exposure for short periods of time was assessed on different microorganisms. Culture plates were exposed to a range of doses of UV-C light, and the reduction in numbers of surviving microorganisms was recorded The results on the biocidal capacity of the microwave generated UV light are presented.

RESUMEN

Metalworking fluids (MWFs) are widely used for cooling and lubricating during the machining process. The worldwide annual usage is estimated to exceed 2 x 10(9)l and the waste could be more than ten times the usage, as the MWFs have to be diluted prior to use. For UK industry the disposal cost is estimated to be up to pound16 million per year. Used MWFs cause high levels of contamination and rancid odours due to the presence of complex chemicals, biocides, etc., so that their treatment and final disposal must be handled carefully. Conventionally this has been done by combined physical and chemical methods but, with tightened legislation, these routes are no longer acceptable. Now, biological treatment is being increasingly adopted as it seems to offer an alternative with the potential for significant cost saving. However, there are significant difficulties in operating bioreactors, such as maintenance of the stability of the microbial communities present in activated sludge plants (ASP). In order to resolve these problems, four major areas need to be considered: (1) the composition of the spent MWF and its inherent biodegradability, (2) the recalcitrant compounds existing in waste MWFs and their impact on microbes, (3) the nature of the microbial consortia and means of optimising it, e.g, temperature and the practical design of the bioreactor and (4) the requirements for nutrient supplements and optimal control conditions. The potential importance of understanding the microbial community has been studied by the use of molecular biological techniques such as polymerase chain reaction (PCR), denaturing gradient gel electrophoresis (DGGE), fatty acid methyl ester (FAME) and fluorescent in situ hybridization (FISH). The application of attached biofilm bioreactors and thermophilic aerobic technology (TAT) has also been studied. This review describes recent advances in each of these areas.
