Unveiling Disparities: Exploring Differential Attainment in Postgraduate Training Within Clinical Oncology

AIMS

Differential attainment (DA) in post graduate medical training is a recognised challenge and refers to unexplained variation across groups when split by several protected characteristics. The Royal College of Radiology is committed to fostering diversity, inclusivity, and equality with the goal of narrowing existing gaps and improving training outcomes.

MATERIALS AND METHODS

This was a mixed methods study aiming to understand the causes of DA with view to helping the RCR develop strategies to address this. A cross-sectional survey was completed by 140 clinical oncology trainees in September 2022. Trainees and trainers (17 and 6 respectively) from across England, Scotland, Wales and Northern Ireland, took part in focus group and interviews from August to December 2022. Quantitative and qualitative data merged and interpreted.

RESULT

Results showed international medical graduates and trainees from ethnic minority backgrounds were more likely to encounter challenges. The qualitative findings were used to identify three themes through which these problems could be framed. The trainee as a "space invader," the hidden curriculum of clinical oncology training and the process of navigating and tacking the training journey.

CONCLUSION

Differential attainment is the product of a complex interplay between the trainee, trainer, and the training environment. Therefore, interventions must be tailored to different people and contexts. At a national level, the RCR can adopt general policies to promote this such as mentorship programmes, protected time for supervision and cultural competency training. Efficacy of proposed interventions for trial and their impact on DA should be evaluated to drive evidence-based changes.

CATastrophic myths part 2: Common misconceptions about the environmental, nutritional, and genetic management of domestic cats and their welfare implications

Despite the cat's popularity as a companion species, many owners and practitioners lack high quality information about important aspects of their behavior and management. Myths, anecdotes, and narratives of cats as 'low maintenance, self-sufficient' animals are pervasive, and the degree to which these may underlie complacency about fully meeting cats' needs is unknown. Several studies suggest that cat welfare and the human-cat bond may benefit from improved education about how to optimize the domestic cat's management and husbandry needs in homes and elsewhere. This paper is the second of a two-part series addressing common myths about cats. The purpose of this paper is to review and debunk common misconceptions about optimal cat care, feeding behavior, genetics, and training. Replacing these misconceptions with scientifically generated information could have a significant impact on the behavioral management of cats, positively influencing their physical health, mental stimulation, and well-being, and reducing stress for both cats and the people caring for them. Areas where further research is required to address ambiguities, and to better meet cats' needs in homes and other environments, are also identified.

CATastrophic myths part 1: Common misconceptions about the social behavior of domestic cats and implications for their health, welfare, and management

Cats are among the most popular pets worldwide, but there are still major gaps in the public's general understanding of their social behaviors and related needs, including for socialization. In addition to these knowledge gaps, people often have negative or ambivalent attitudes about cats, which can directly impact their welfare outcomes. Insufficient attention to the behavioral ecology and development of cat sociality, along with failure to account for their highly variable individual preferences and tolerance for social behaviors can lead them to experience distress that undermines both their welfare and the human-animal bond. As Part 1 of a two-part series addressing common myths about cats, the purpose of this first paper is to review and debunk common misperceptions about the social needs and behaviors of cats, including misunderstandings about their social lives and abilities to bond with humans. We also identify where opportunities exist to improve socialization of cats and to advance research in related areas that might better support their behavior and welfare needs.

Management and behavioral factors associated with rehoming outcomes of dogs retired from commercial breeding kennels

Rehoming is a potentially stressful process for dogs retired from commercial breeding (CB) kennels, as they may struggle to cope with the myriad novel factors associated with transitioning to a home environment. Failure to adapt may increase the risk of an unsuccessful adoption, jeopardizing dog welfare and the benefits of rehoming programs. Little is known about relationships between welfare in the kennel of origin and a dog's ability to transition to a family home. This study aimed at investigating the welfare states of dogs retiring from CB kennels in relation to varying management practices across kennels, and understanding how behavioral and management factors might be associated with rehoming outcomes. A total of 590 adult dogs from 30 US CB kennels were included in the study. Dog behavioral and physical health metrics were collected through direct observation, while management information was obtained through a questionnaire. One month after adoption, 32 dog owners completed a follow-up questionnaire (CBARQ). A principal component analysis extracted four behavioral components (PCs) which included food interest, sociability, boldness, and responsiveness. Factors such as sex, housing, breed, and the number of dogs per caretaker were reported as significant sources of variation for some of those PC scores (p<0.05). For instance, lower dog to caretaker ratio was linked to better health, sociability, and food interest scores. Significant relationships were also found between in-kennel PC scores and CBARQ scores (p<0.05). Most interestingly, higher levels of sociability in the kennel were associated with lower levels of social and non-social fear, and higher trainability after rehoming. Overall, dogs were found to be physically healthy, and a moderate proportion showed fearful responses toward either social or non-social stimuli. Results suggest that a comprehensive behavioral assessment of rehoming candidates while in the kennel may help identify dogs that may have more difficulty coping during rehoming. The implications for developing management strategies and necessary interventions that support positive dog welfare outcomes within the kennel and when rehomed are discussed.

The Effect of Early Neurological Stimulation on Puppy Welfare in Commercial Breeding Kennels

Throughout their lives, dogs may experience various stressful events. Early neurological stimulation (ENS), which was shown to alter stress responses beneficially in some animals, has not been fully explored in dogs. Seventy-six small-breed puppies from one commercial breeding kennel were divided into three treatment groups: ENS, held, and control. Puppies in the ENS group received 30 s of handling exercises for 21 days after birth; puppies in the held group were simply held for the same amount of time. Puppies in the control group were managed as per normal breeder practices (i.e., routine husbandry and physical health checks). Physical health was assessed weekly, and puppies were generally healthy and clean. Behavioral responses to stranger approach and isolation tests were evaluated pre- and post-ground-transportation to a distributor. Puppies were more affiliative toward a stranger post-isolation than pre-isolation (p < 0.001), and post-transport than pre-transport (p < 0.001). At the distributor, puppies in the isolation test spent less time in exploratory locomotion (p < 0.001) and vocalized more than at the breeder’s kennel (p = 0.011). Treatment did not affect these results. Overall, the results suggest that the type of ENS used in this study may not provide the purported benefits to puppies’ stress responses in commercial breeding populations.

The Effect of Transportation on Puppy Welfare from Commercial Breeding Kennels to a Distributor

Many puppies from commercial breeding kennels (CBKs) are transported by ground from their kennels of origin to a distributor. This experience may elicit fear and stress during a sensitive developmental period, which may in turn negatively impact the puppies’ short- and long-term welfare. This study aimed to measure short-term effects of transportation on puppy welfare metrics. Eight-week-old puppies (n = 383) from 12 CBKs were tested at their kennels (pre-trans) and ~48 h after arriving at a distributor (post-trans). At each location, puppies underwent an isolation test, a stranger-approach test, and a physical health assessment. Behavioral responses to testing were scored from videos. Fecal glucocorticoid metabolites (FGM), fecal secretory immunoglobulin A (sIgA), and presence of intestinal parasites were also analyzed. Linear mixed-effects models identified decreased exploration (p < 0.001), and increased locomotion (p < 0.001) and escape attempts (p = 0.001) during the post-trans isolation test. Increased affiliative behavior (p < 0.001), FGM (p < 0.001) and sIgA (p = 0.014) were also observed post-trans. Findings support good physical health both pre- and post-trans, while behavioral and physiological changes suggest increased puppy distress post-trans. Higher post-transport affiliative behavior may indicate that puppies sought social support as a coping strategy after experiencing transport-related distress. Future studies should explore the efficacy of transportation-related interventions to mitigate puppy distress.

498 Late-Breaking: Identifying Meaningful Measures of Dam and Puppy Welfare in Commercial-breeding (CB) Kennels

Maternal factors such as fear and stress influence offspring welfare in many species, but this area of research has been underexplored in dogs. As a large proportion of society’s dogs originate from commercial-breeding (CB) kennels, further investigation in this environment is crucial to ensure canine welfare. The current study aimed to refine a set of welfare metrics used to explore associations between maternal factors and litter welfare in CB kennels. Dams (n = 28) from five USDA-licensed CB kennels were tested at 6 and 1-week prepartum, and 4 and 8-weeks postpartum using a stranger approach test, physical health assessment, exposure to novel stimuli, social isolation test, hair cortisol concentration, fecal glucocorticoid metabolites (FGM) and fecal immunoglobulin A (IgA) concentrations. Puppies (n = 138) were tested at 4 (4W) and 8-weeks (8W) old using equivalent measures. Preliminary analyses of the metrics collected during puppy social isolation revealed that locomotion was positively correlated with exploration (4W: rs=0.46, P &lt; 0.001; 8W: rs=0.39, P &lt; 0.001), escape attempt duration (4W: rs=0.26, P = 0.002; 8W: rs=0.31, P &lt; 0.001), frequency of stress behaviors (4W: rs=0.22, P = 0.01; 8W: rs=0.40, P &lt; 0.001), vocalization (4W: rs=0.18, p=0.04; 8W: rs=0.20, P = 0.02), and fecal IgA (4W: rs=0.24, P = 0.05). Stationary behavior was negatively correlated with escape attempt duration (4W: rs=-0.37, P &lt; 0.001; 8W: rs=-0.43, P &lt; 0.001), frequency of stress behaviors (4W: rs=-0.22, P = 0.01; 8W: rs=-0.32, P &lt; 0.001), and physiologic metrics (4W: fecal IgA rs=-0.25, P = 0.04; 8W: FGM rs=-0.23, P = 0.01). Results suggest that, in response to social isolation, 4W and 8W old puppies exhibit one of two coping styles, proactive or passive, and the latter is associated with lower activation of the immune and stress response. The outcomes of this study will inform future research exploring maternal risk factors, including behavioral and physiologic stressors, affecting puppy developmental welfare in CB kennels.

76 Investigating the effects of increased soluble fiber and incremental exercise on the voluntary physical activity and behaviour of sled dogs

Optimization of the insoluble:soluble fibers in the diets of dogs can improve gastrointestinal health by increasing commensal bacterial growth. A growing body of research suggests that improved gut health can influence behavior via the gut-brain axis. Therefore, the objectives of this study were to investigate the effects of an increased soluble fiber diet on the behavior and voluntary activity of actively training, client-owned Siberian huskies. Fourteen dogs were blocked for age, BW and sex and randomly allocated to either the control or treatment groups. The control group was fed a dry extruded diet that contained an insoluble:soluble fiber ratio of 4:1, and the treatment group was fed a dry extruded diet that contained an insoluble:soluble fiber ratio of 3:1. All dogs underwent eight weeks of incremental conditioning where they trained four days a week. Once a week, a 5-minute video recording was taken immediately pre- and post-exercise to evaluate behaviors. Activity monitors were used to record voluntary activity on two rest days and one active day during weeks -1, 1, 4, 5, and 7. All behavioral and physical activity count data were analyzed using a repeated measures mixed model to test for differences between dietary treatments and week. No differences were observed between treatment or control dogs for any behavior or voluntary physical activity levels (P &gt; 0.05); however, all dogs experienced an exercise-induced reduction in locomotive behaviors prior to exercise throughout the 8-week conditioning period (P &lt; 0.05). Additionally, all dogs were more active during the second consecutive day of rest relative to the first (P &lt; 0.05). These data suggest that while increased soluble fiber in the diets of sled dogs may not affect their behavior, the exercise-related reduction in activity observed begins to recover within one rest day.

The Behavioural Effects of Innovative Litter Developed to Attract Cats

Urination and/or defecation outside a designated location has been reported as the most common behavioural reason for surrendering a cat and comprises approximately 30% of cat intakes to shelters. The objective of this study was to determine whether cats would increase in-box elimination when provided a plant-based litter product with attractant (ATTRACT) compared to the same plant-based litter product without attractant (PLANT). Sixteen cats were split into two equal cohorts based on availability from the shelter and group-housed in an enriched room with eight identical litter boxes arranged in a circular pattern equidistant from each other. Following a two-week room acclimation and transition period from clay litter to PLANT litter, boxes were designated either PLANT or ATTRACT litter, balancing for cats' prior box location preferences. For 14 days following litter allocation, cat behaviours such as sniffing, digging, covering, urinating, and defecating were video recorded for 12 h daily. The cats urinated more often in the ATTRACT litter, suggesting that they preferred the ATTRACT litter for urination more than the PLANT litter (p < 0.05). The most significant differences observed were between genders, with males spending significantly more time sniffing and performing urination behaviours (p < 0.05). These results suggest that litter with an attractant may be more effective in eliciting usage for urination, as compared to a litter without the additive.

Evaluation of Movement Restriction Zone Sizes in Controlling Classical Swine Fever Outbreaks

The objective of this study was to compare the impacts of movement restriction zone sizes of 3, 5, 9, and 11 km with that of 7 km (the recommended zone size in the United States) in controlling a classical swine fever (CSF) outbreak. In addition to zone size, different compliance assumptions and outbreak types (single site and multiple site) were incorporated in the study. Three assumptions of compliance level were simulated: baseline, baseline ± 10%, and baseline ± 15%. The compliance level was held constant across all zone sizes in the baseline simulation. In the baseline ± 10% and baseline ± 15% simulations, the compliance level was increased for 3 and 5 km and decreased for 9 and 11 km from the baseline by the indicated percentages. The compliance level remained constant in all simulations for the 7-km zone size. Four single-site (i.e., with one index premises at the onset of outbreak) and four multiple-site (i.e., with more than one index premises at the onset of outbreak) CSF outbreak scenarios in Indiana were simulated incorporating various zone sizes and compliance assumptions using a stochastic between-premises disease spread model to estimate epidemic duration, percentage of infected, and preemptively culled swine premises. Furthermore, a risk assessment model that incorporated the results from the disease spread model was developed to estimate the number of swine premises under movement restrictions that would experience animal welfare outcomes of overcrowding or feed interruption during a CSF outbreak in Indiana. Compared with the 7-km zone size, the 3-km zone size resulted in a longer median epidemic duration, larger percentages of infected premises, and preemptively culled premises (P’s < 0.001) across all compliance assumptions and outbreak types. With the assumption of a higher compliance level, the 5-km zone size significantly (P < 0.001) reduced the epidemic duration and percentage of swine premises that would experience animal welfare outcomes in both outbreak types, whereas assumption of a lower compliance level for 9- and 11-km zone sizes significantly (P < 0.001) increased the epidemic duration and percentage of swine premises with animal welfare outcomes compared with the 7-km zone size. The magnitude of impact due to a zone size varied across the outbreak types (single site and multiple site). Overall, the 7-km zone size was found to be most effective in controlling CSF outbreaks, whereas the 5-km zone size was comparable to the 7-km zone size in some circumstances.

Show Horse Welfare: The Viewpoints of Judges, Stewards, and Show Managers

The purpose of this study was to gain a better understanding of the current state of stock-type show horse welfare based on the perceptions of show officials and to identify potential means of preventing and intervening in compromises to show horse welfare. Thirteen horse show officials, including judges, stewards, and show managers, were interviewed. Findings revealed the officials had an incomplete understanding of nonhuman animal welfare and a high level of concern regarding the public's perception of show horse welfare. The officials attributed most of the frequently observed compromises to show horse welfare to (a) novices', amateurs', and young trainers' lack of experience or expertise, and (b) trainers' and owners' unrealistic expectations and prioritization of winning over horse welfare. The officials emphasized a need for distribution of responsibility among associations, officials, and individuals within the industry. Although the officials noted recent observable positive changes in the industry, they emphasized the need for continued improvements in equine welfare and greater educational opportunities for stakeholders.

Methods to address poultry robustness and welfare issues through breeding and associated ethical considerations

As consumers and society in general become more aware of ethical and moral dilemmas associated with intensive rearing systems, pressure is put on the animal and poultry industries to adopt alternative forms of housing. This presents challenges especially regarding managing competitive social interactions between animals. However, selective breeding programs are rapidly advancing, enhanced by both genomics and new quantitative genetic theory that offer potential solutions by improving adaptation of the bird to existing and proposed production environments. The outcomes of adaptation could lead to improvement of animal welfare by increasing fitness of the animal for the given environments, which might lead to increased contentment and decreased distress of birds in those systems. Genomic selection, based on dense genetic markers, will allow for more rapid improvement of traits that are expensive or difficult to measure, or have a low heritability, such as pecking, cannibalism, robustness, mortality, leg score, bone strength, disease resistance, and thus has the potential to address many poultry welfare concerns. Recently selection programs to include social effects, known as associative or indirect genetic effects (IGEs), have received much attention. Group, kin, multi-level, and multi-trait selection including IGEs have all been shown to be highly effective in reducing mortality while increasing productivity of poultry layers and reduce or eliminate the need for beak trimming. Multi-level selection was shown to increases robustness as indicated by the greater ability of birds to cope with stressors. Kin selection has been shown to be easy to implement and improve both productivity and animal well-being. Management practices and rearing conditions employed for domestic animal production will continue to change based on ethical and scientific results. However, the animal breeding tools necessary to provide an animal that is best adapted to these changing conditions are readily available and should be used, which will ultimately lead to the best possible outcomes for all impacted.

Effects of stressors on the behavior and physiology of domestic cats

Feline interstitial cystitis (FIC) is a chronic pain syndrome of domestic cats. Cats with FIC have chronic, recurrent lower urinary tract signs (LUTS) and other comorbid disorders that are exacerbated by stressors. The aim of this study was to evaluate behavioral and physiological responses of healthy cats and cats diagnosed with FIC after exposure to a five day stressor. Ten healthy cats and 18 cats with FIC were housed at The Ohio State University Veterinary Medical Center (OSUVMC) vivarium. All cats were housed in enriched cages for at least one year prior to the experiment. Cats had daily play time and socialization outside of the cage, food treats and auditory enrichment. The daily husbandry schedule was maintained at a consistent time of day and cats were cared for by two familiar caretakers. During the test days, cats were exposed to multiple unpredictable stressors which included exposure to multiple unfamiliar caretakers, an inconsistent husbandry schedule, and discontinuation of play time, socialization, food treats, and auditory enrichment. Sickness behaviors (SB), including vomiting, diarrhea, anorexia or decreased food and water intake, fever, lethargy, somnolence, enhanced pain-like behaviors, decreased general activity, body care activities (grooming), and social interactions, were recorded daily. Blood samples were collected in the morning, before and after the stress period, for measurement of serum cortisol concentration, leukocytes, lymphocytes, neutrophils, neutrophil: lymphocyte (N:L) ratio and mRNA for the cytokines interleukin-1 beta (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α). Overall, the short term stressors led to a significant increase in SB in both healthy cats and cats with FIC, whereas lymphopenia and N:L changes occurred only in FIC cats. Daily monitoring of cats for SB may be a noninvasive and reliable way to assess stress responses and overall welfare of cats housed in cages.
