Do Animal Welfare Education Campaigns Really Work? An Evaluation of the RSPCA's #DogKind Campaign in Raising Awareness of Separation-Related Behaviours in UK Dog Owners

One of the main aims of companion animal welfare charities is to educate the public about the needs of animals. This is frequently performed through campaigns focusing on specific aspects of welfare. The Royal Society for the Prevention of Cruelty to Animals (RSPCA), Britain's biggest animal welfare charity, launched the nationwide #DogKind campaign in March 2019. Targeted mainly at 25-34-year-olds, the campaign aimed to increase awareness of separation-related behaviour (SRB) among dog owners and encourage them to seek help for SRB from reliable sources. This research involved a quasi-experimental, non-equivalent control group design evaluating the campaign's effectiveness. It was conducted through a series of online surveys at three different time points: before the launch of the campaign (n = 2002), six months after (n = 2423), and, again, two months later (n = 269), during which we asked the same questions regarding knowledge of SRB. An experimental trial of 269 participants tested whether accessing a video alongside the campaign web pages increased the effectiveness of the campaign objectives. Overall, the campaign appeared to be effective in reaching its target audience but not at raising awareness of SRB or increasing the number of owners intending to seek help. The inclusion of a video in the campaign made no difference to its effectiveness. This study shows that this campaign had limited success in achieving its targets and highlights the importance of thorough evaluations of education interventions that aim to improve the welfare of companion animals.

What Do We Know about Dog Owners? Exploring Associations between Pre-Purchase Behaviours, Knowledge and Understanding, Ownership Practices, and Dog Welfare

Despite many dogs living in homes in the UK, there is still more to know about the welfare of those individual animals. Past research has shown that owners' thoughts and behaviours have a substantial impact on their dog's welfare. This study aimed to better understand owners' pre-purchase behaviours, knowledge and understanding, and ownership practices, and explore any associations between these factors and their dog's welfare. We conducted further analysis of the data collected by People's Dispensary for Sick Animals (PDSA) for their 2017 PDSA Animal Welfare (PAW) Report (n = 1814). We extracted variables to describe owner demographics (7), pre-purchase behaviours (1), knowledge and understanding (4), welfare indicators, (2) and ownership practices (4), and we tested for an association between these variables. We found more pre-purchase research was carried out by younger respondents and those with a higher education level. Also, more research was associated with feeling more informed about the five welfare needs and knowing to seek help for behaviour from appropriate sources. Overall, the study found several novel and significant results worthy of note and further exploration but did not find any strong connections between the variables.

Are postoperative antibiotics required after orthognathic surgery?

The aim of this study was to investigate and compare the frequency of surgical site infection (SSI) between orthognathic patients who received only intraoperative antibiotics and patients who received intraoperative antibiotics plus postoperative antibiotics. A retrospective study was performed of patients treated by a single surgeon over the years 2006-2012 and 2016-2019. The primary predictor variable was antibiotic exposure. The control group received no postoperative prophylactic antibiotics. The study group received postoperative antibiotics. Both groups received prophylactic intraoperative antibiotics and performed postoperative chlorhexidine rinses. The primary outcome was SSI frequency. Univariate, bivariate, and multiple logistic regression analyses were performed; statistical significance was set at P ≤ 0.05. The sample comprised 333 patients. Their mean age was 30.7 ± 11.8 years. The study group included 129 patients (38.7%); the control group included 204 patients (61.3%). The frequency of SSI was 17.1% in the study group and 26.5% in the control group (P = 0.048). In the multivariable logistic regression, only alcohol consumption was significantly associated with an increased risk of SSI (odds ratio 2.46, 95% confidence interval 1.36-4.44; P = 0.003). In patients undergoing orthognathic surgery, postoperative antibiotic exposure in addition to intraoperative prophylaxis approached but was not statistically significant for a decreased risk of SSI (P = 0.067).

309 A FRAILTY CENSUS OF INPATIENTS AGED 65 AND OVER ADMITTED TO A MODEL 4 HOSPITAL

Background

Frailty is a risk factor for in-hospital mortality, long hospital stay and functional decline at discharge. Profiling the prevalence and level of frailty within the acute hospital setting is vital to ensure evidence-based practice and service development within the construct of frailty.

Methods

All patients aged ≥65 years and admitted to a medical or surgical inpatient setting, were screened over a 12-hour period (08:00-20:00) using validated frailty and co-morbidity scales. Age and Gender Demographics, Clinical Frailty Scale (CFS), Charlson Co-morbidity Index (CHI) and admitting specialty (Medical/Surgical) were collected. The data was fully anonymised and ethical approval was granted. Descriptive statistics were used to profile the cohort and Chi-squared tests applied for comparisons.

Results

Within a sample of 413 patients, 291(70%) were ≥65yrs. Of this cohort, 202(70%) were ≥75yrs. 207(71%) utilised in-patient medical services and 121(41%) surgical services while 37(12%) used both. The mean CFS was 6 indicating moderate frailty levels and the mean CCI score was 4 denoting moderate co-morbidity. Overall: 195(67%) had moderate-severe frailty (CSF ≥6) while 218 (75%) had moderate-severe co-morbidity (CCI Mod 3-4, Severe ≥5). Associations with age >75 and frailty (p=0.001) and medical service usage and frailty (p=0.004) were established. No significant differences were observed across genders for CFS (p=0.110) and CCI (p=0.465).

Conclusion

There is a high prevalence of frailty and co-morbidity within the admitted patient cohort ≥65yrs. Overcrowding across the hospital system and higher levels of frailty and comorbidity will contribute to increased lengths of stay and the need for specialist intervention, particularly for those ≥75yrs who represented 70% of patients screened. With an increased focus on the integration of care for older adults across care transitions, there is a clear need for expansion of frailty-based services and staff training in frailty care across the hospital and community setting.

Expanding the field: using digital to diversify learning in outdoor science

This is an empirical study of teacher experiences with school learners (7-18 years) engaging in cross-curricular environmental science during the COVID-19 pandemic. The study focuses on #FieldworkLive, a programme of live-streamed outdoor science lessons produced by the Field Studies Council and Encounter Edu during the UK lockdown (April - May 2020). The experiences of approximately 377,000 teachers and students from 32 countries were captured using an online survey and direct staff consultation. This delivery method allowed us to reach untapped audiences and to provide learners with a virtual fieldwork experience during the constraints of lockdown. Teachers were highly positive about the technology-enhanced learning which provided them with novel perspectives and approaches for the classroom. We propose a model for the affordances provided by this delivery approach based on the Technological Pedagogical Content Knowledge framework. The Field Studies Council has developed a flexible package of multimedia resources for secondary schools as a route to enriching outdoor experience and learning despite the constraints imposed by the pandemic.

Changing How We Teach Acid-Base Chemistry: A Proposal Grounded in Studies of the History and Nature of Science Education

We propose explicit and implicit approaches for the teaching of acid-base chemistry based on research into the history and nature of science (NoS). To support these instructional proposals, we identify four rationales for students to understand acid-base processes: daily life, socio-scientific, curriculum, and history of science. The extensive bibliography on misconceptions at all educational levels justifies the need for a change from the usual pedagogical approaches to teaching the acid-base domain (traditionally involving conceptual-focused teaching) to a deeper and more meaningful approach that provides (implicitly or explicitly) a chance to reflect on how scientific knowledge is constructed. Controversial moments in science from 1923, when three researchers (Bronsted, Lowry, and Lewis) independently enunciated two theories from two different paradigms (dissociation and valence electron), underpin our first sequence with an explicit NoS approach for both lower secondary school and upper secondary or university levels. Our inquiry teaching cycle promotes the transformation of a hands-on activity (using cabbage as an indicator) into an inquiry, and subsequently, we use an historical model to propose a sequence of activities based on the modeling cycle of Couso and Garrido-Espeja for lower secondary school. Finally, we identify some implications for a model-focused teaching approach for upper secondary and university levels using more sophisticated models.

Early outcome of cardiac surgery in dialysis-dependent end-stage renal failure patients

INTRODUCTION

Preoperative dialysis-dependent renal failure is a strong independent risk factor for in-hospital mortality and morbidity after open heart surgery. This retrospective study analyses the early outcome in dialysis-dependent renal failure patients who underwent elective open-heart surgery in the Institut Jantung Negara (IJN).

METHODS

We retrospectively analyse a series of 228 consecutive postoperative patients with dialysis-dependent (end stage renal failure (ESRF)) admitted to the adult cardiothoracic ICU in IJN between January 2012 and December 2016.

RESULTS

The overall early mortality rate included 34 patients (15.8%). Patients with ESRF underwent combined procedure recorded a very high mortality rate at 56.3%. Twenty-four patients (11.2%) needed resternotomy for postoperative bleeding or cardiac temponade. Postoperative mediastinitis rate was high, involving 13 patients (6%). The neurological and gastrointestinal complications rate were recorded at 2.3% (5 patients) and 6% (13 patients) respectively. In the group of patients (n=199) with sinus rhythm during the preoperative period, 100 patients (50.3%) developed postoperative AF. 77 patients (35.8%) stayed in hospital for more than 14 days.

CONCLUSIONS

dialysis-dependent patients undergoing cardiac surgery poses higher perioperative risk of mortality and morbidity of 3-4 times higher compared to those patients with normal renal function. IJN shows acceptable perioperative risk of mortality and morbidity which is comparable to other centres.

Method Extension Study to Validate Applicability of AOAC Official Method 996.14 Assurance® Polyclonal Enzyme Immunoassay for Detection of Listeria monocytogenes and Related Listeria spp. from Environmental Surfaces: Collaborative Study

Test portions from 3 environmental surface types, representative of typical surfaces found in a food production facility, were analyzed by the Assurance®Listeria Polyclonal Enzyme Immunoassay (EIA) and the U.S. Department of Agriculture/Food Safety and Inspection Service (USDA/FSIS) culture method for Listeria monocytogenes and related Listeria species. In all cases, naturally contaminated environmental test samples were collected from an actual food production facility by sponge or swab. Test samples from concrete surfaces were collected by both swab and sponge; sponge test samples were collected from rubber surfaces, and swabs were used to sample steel surfaces. Test portions from each surface type were simultaneously analyzed by both methods. A total of 23 collaborators, representing government agencies, as well as private industry in both the United States and Canada, participated in the study. During this study, a total of 550 test portions and controls was analyzed and confirmed, of which 207 were positive and 336 were negative by both methods. Six test portions were positive by culture, but negative by the EIA. Three test portions were negative by culture, but positive by the EIA. Two test portions were negative by EIA and by culture, but confirmed positive when EIA enrichment broths were subcultured to selective agars. The data reported here indicate that the Assurance®Listeria EIA method and the USDA/FSIS culture method are statistically equivalent for detection of L. monocytogenes and related Listeria species from environmental surfaces taken by sponges or swabs.

Visual Immunoprecipitate Assay Eight Hour Method for Detection of Enterohemorrhagic Escherichia coli O157:H7 in Raw and Cooked Beef (Modification of AOAC Official Method 996.09): Collaborative Study

AOAC Official Method 996.09, Visual Immunoprecipitate Assay (VIP®) for Escherichia coli O157:H7, was modified to incorporate a new enrichment protocol using BioControl EHEC8™ medium for testing raw and cooked beef. Foods were tested by VIP assay and the U.S. Department of Agriculture/Food Safety and Inspection Service (USDA/FSIS) enrichment procedure and the FDA Bacteriological Analytical Manual (BAM) isolation and confirmation techniques. A total of 15 collaborators participated. Raw and cooked ground beef were inoculated with E. coli O157:H7 at 2 different levels: a high level, where predominantly positive results were expect d, and a low level where fractional recovery was anticipated. Collaborators tested 396 test portions and controls by both methods, for a total of 792 test portions. Of the 396 paired test portions, 75 were positive and 230 were negative by both the VIP and culture methods. Eleven test portions were presumptively positive by VIP and could not be confirmed culturally; 32 were negative by VIP, but confirmed positive by culture; and 65 were negative by the culture method, but confirmed positive by the VIP method. There was no statistical difference between results obtained with the VIP for EHEC 8 h method and the culture method except for cooked beef, where the VIP had significantly higher recovery for one inoculation level.

Assurance® Enzyme Immunoassay Eight Hour Method for Detection of Enterohemorrhagic Escherichia coli O157:H7 in Raw and Cooked Beef (Modification of AOAC Official Method 996.10): Collaborative Study

AOAC Official Method 996.10, Assurance® Enzyme Immunoassay (EIA) for Escherichia coli O157:H7 (EHEC), was modified to incorporate a new enrichment protocol using BioControl EHEC8™ medium for testing raw and cooked beef. Foods were tested by EIA and the U.S. Department of Agriculture/Food Safety and Inspection Service (USDA/FSIS) enrichment conditions and the FDA Bacteriological Analytical Manual (BAM) isolation and confirmation techniques.

Nine test portions were positive by culture, but negative by the VIP. Five test portions were negative by culture, but positive by the VIP. Four test portions were negative by VIP and by culture, but confirmed positive when VIP enrichment broths were subcultured to selective agars. The data reported here indicate that the VIP method and the USDA/FSIS culture method are statistically equivalent for detection of L. monocytogenes and related Listeria species from environmental surfaces taken by sponges or swabs.

Modification of Enrichment Protocols for TECRA Listeria Visual Immunoassay Method 995.22: Collaborative Study

A collaborative study was conducted to validate new enrichment methods for the TECRA Listeria Visual Immunoassay (TLVIA). These new methods incorporate a newly formulated medium, TECRA Listeria Enrichment Broth, which does not contain the highly toxic antifungal agent, cycloheximide. The new procedures will provide an alternative to the enrichment procedures described in AOAC Method 995.22. Three food types (raw ground beef, lettuce, and ice cream) were analyzed in the United States, and 2 food types (cooked turkey and cooked fish fillets) were analyzed in Australasia. Thirty collaborators participated in the study, 16 in Australasia and 14 in the United States. With the exception of one batch of ground beef, comparison of the proportion of positive test portions (p ≥ 0.05) showed no significant difference between the TLVIA and the reference method for the 5 foods at 3 inoculation levels. For the one batch of naturally contaminated raw ground beef, the TLVIA gave significantly more confirmed positive results than the reference method.

Comparison of hyperspectral classification methods for the analysis of cerium oxide nanoparticles in histological and aqueous samples

Hyperspectral imaging (HSI) and classification are established methods that are being applied in new ways to the analysis of nanoscale materials in a variety of matrices. Typically, enhanced darkfield microscopy (EDFM)-based HSI data (also known as image datacubes) are collected in the wavelength range of 400-1000 nm for each pixel in a datacube. Utilising different spectral library (SL) creation methods, spectra from pixels in the datacube corresponding to known materials can be collected into reference spectral libraries (RSLs), which can be used to classify materials in datacubes of experimental samples using existing classification algorithms. In this study, EDFM-HSI was used to visualise and analyse industrial cerium oxide (CeO₂ ; ceria) nanoparticles (NPs) in rat lung tissues and in aqueous suspension. Rats were exposed to ceria NPs via inhalation, mimicking potential real-world occupational exposures. The lung tissues were histologically prepared: some tissues were stained with hematoxylin and eosin (H&E) and some were left unstained. The goal of this study was to determine how HSI and classification results for ceria NPs were influenced by (1) the use of different RSL creation and classification methods and (2) the application of those methods to samples in different matrices (stained tissue, unstained tissue, or aqueous solution). Three different RSL creation methods - particle filtering (PF), manual selection, and spectral hourglass wizard (SHW) - were utilised to create the RSLs of known materials in unstained and stained tissue, and aqueous suspensions, which were then used to classify the NPs in the different matrices. Two classification algorithms - spectral angle mapper (SAM) and spectral feature fitting (SFF) - were utilised to determine the presence or absence of ceria NPs in each sample. The results from the classification algorithms were compared to determine how each influenced the classification results for samples in different matrices. The results showed that sample matrix and sample preparation significantly influenced the NP classification thresholds in the complex matrices. Moreover, considerable differences were observed in the classification results when utilising each RSL creation and classification method for each type of sample. Results from this study illustrate the importance of appropriately selecting HSI algorithms based on specific material and matrix characteristics in order to obtain optimal classification results. As HSI is increasingly utilised for NP characterisation for clinical, environmental and health and safety applications, this investigation is important for further refining HSI protocols while ensuring appropriate data collection and analysis.

Bespoke video vignettes - an approach to enhancing reflective learning developed by dental undergraduates and their clinical teachers

This study explores the selective use of video as a medium to support reflective processes as related to dental undergraduate learning. With the objective of developing and enhancing high-quality adult dental care, the use of compiled video materials created in an undergraduate clinical setting was investigated. Video cameras were used to capture elements of reflection-in-action and reflection-on-action typically found during everyday clinical practice. 'Gold standard' or 'textbook outcomes' are rarely, if ever, fully achieved in dental practice. Real-life clinical experiences offer challenges and opportunities for both teachers and students to engage with reflective learning processes. The materials generated allowed for an experience of individual reflective learning and the creation of a data bank or archive with potential use for the benefit of a wider student cohort. Various aspects of the students' views and comments on the process of reflection were reported and explored by means of a semi-structured focus group moderated by a linked educational advisor.

Cradle-to-farm gate environmental footprints of beef cattle production in Kansas, Oklahoma, and Texas

A comprehensive national assessment of the sustainability of beef is being conducted by the U.S. beef industry. The first of 7 regions to be analyzed is Kansas, Oklahoma, and Texas. A survey and visits conducted throughout the region provided data on common production practices. From these data, representative ranch and feedyard operations were defined and simulated for the varying climate and soil conditions throughout the region using the Integrated Farm System Model. These simulations predicted environmental impacts of each operation including cradle-to-farm gate footprints for greenhouse gas emissions, fossil-based energy use, nonprecipitation water use, and reactive N loss. Individual ranch and feedyard operations were linked to form 28 representative production systems. A weighted average of the production systems was used to determine the environmental footprints for the region where weighting factors were developed based on animal numbers reported in the survey and agricultural statistics data. Along with the traditional beef production systems, Holstein steer and cull cow production from the dairy industry in the region were also modeled and included. The carbon footprint of all beef produced was 18.3 ± 1.7 kg CO2 equivalents (CO2e)/kg carcass weight (CW) with the range in individual production systems being 13 to 25 kg CO2e/kg CW. Energy use, water use, and reactive N loss were 51 ± 4.8 MJ/kg CW, 2,470 ± 455 L/kg CW, and 138 ± 12 g N/kg CW, respectively. The major portion of each footprint except water use was associated with the cow-calf phase; most of the nonprecipitation water use was attributed to producing feed for the finishing phase. These data provide a baseline for comparison as new technologies and strategies are developed and implemented to improve the sustainability of cattle production. Production information also will be combined with processing, marketing, and consumer data to complete a comprehensive life cycle assessment of beef.
