Breeding for resilience in finishing pigs can decrease tail biting, lameness and mortality.

BACKGROUND: Previous research showed that deviations in longitudinal data are heritable and can be used as a proxy for pigs' general resilience. However, only a few studies investigated the relationship between these resilience traits and other traits related to resilience and welfare. Therefore, this study investigated the relationship between resilience traits derived from deviations in longitudinal data and traits related to animal resilience, health and welfare, such as tail and ear biting wounds, lameness and mortality. RESULTS: In our experiment, 1919 finishing pigs with known pedigree (133 Piétrain sires and 266 crossbred dams) were weighed every 2 weeks and scored for physical abnormalities, such as lameness and ear and tail biting wounds (17,066 records). Resilience was assessed via deviations in body weight, deviations in weighing order and deviations in observed activity during weighing. The association between these resilience traits and physical abnormality traits was investigated and genetic parameters were estimated. Deviations in body weight had moderate heritability estimates (h2 = 25.2 to 36.3%), whereas deviations in weighing order (h2 = 4.2%) and deviations in activity during weighing (h2 = 12.0%) had low heritability estimates. Moreover, deviations in body weight were positively associated and genetically correlated with tail biting wounds (rg = 0.22 to 0.30), lameness (rg = 0.15 to 0.31) and mortality (rg = 0.19 to 0.33). These results indicate that events of tail biting, lameness and mortality are associated with deviations in pigs' body weight evolution. This relationship was not found for deviations in weighing order and activity during weighing. Furthermore, individual body weight deviations were positively correlated with uniformity at the pen level, providing evidence that breeding for these resilience traits might increase both pigs' resilience and within-family uniformity. CONCLUSIONS: In summary, our findings show that breeding for resilience traits based on deviations in longitudinal weight data can decrease pigs' tail biting wounds, lameness and mortality while improving uniformity at the pen level. These findings are valuable for pig breeders, as they offer evidence that these resilience traits are an indication of animals' general health, welfare and resilience. Moreover, these results will stimulate the quantification of resilience via longitudinal body weights in other species.

Psychological Care Augmented by Telemedicine after a Polar Bear Encounter at an Arctic Research Station: A Case Report.

Background: Psychologically stressful events can be particularly challenging in the wilderness or extreme environments due to a lack of immediate medical or psychological support. Telemedicine consultations may provide a means to supply medical providers in austere environments with expertise when confronted with these situations. Methods: In this study, we detail a case of psychological care imparted to residents at a remote, arctic research station after they encountered a polar bear. The health care provider at the camp was not a dedicated mental health professional but was able to deliver psychological care with assistance from a trained provider through use of telemedicine. We provide a brief overview of the evidence behind psychological first aid and incident support sessions for the treatment of stress injuries. We also review the evidence for telemedicine for psychological care in wilderness situations and describe its use in this scenario. Results: All station residents were able to resume regular arctic activities. Resident feedback was that the sessions were advantageous. Conclusions: We anticipate the need for psychological care in austere situations to increase in the future, and further training in this field and the advancement of telemedicine consultation will be of benefit to wilderness providers.

Direct and indirect psychological impacts of shark-bite events.

OBJECTIVE: Shark bites are rare, with intense media exposure. There are no known studies of the psychological impacts of this specific type of traumatic event. This is the first study that describes those directly and indirectly affected, and evaluates the prevalence of post-traumatic stress disorder (PTSD) and related risk factors. METHODS: In total, 124 members of an Australian shark-bite peer-support group were invited to complete an online survey assessing demographic, event, media and psychological factors. Response rate was 48% ( n = 60, 63% male, 44 ± 14 years). Retrospective and current measures of PTSD (PTSD Checklist for DSM-5 [PCL-5]) and suicidality (Suicidal Ideation Attributes Scale [SIDAS-5]) were used. RESULTS: Post-event PTSD was prevalent in this sample ( n = 16/59, 27.1%, 95% confidence interval [CI] = [15.4, 38.8]), but less so currently ( n = 2/55, 3.6%, 95% CI = [0.0, 8.7]). In addition, nine ( n = 9/59, 15.3%, 95% CI = [5.8, 24.7]) had subthreshold, but highly symptomatic, syndromes post event. There was no association of PTSD with direct/indirect bite involvement, gender, or prior trauma. Two respondents were at risk of suicidal behaviour. PTSD was commonly reported by those without a partner (odds ratio [OR] = 5.91, 95% CI = [1.52, 22.99], p = 0.01) or with two friends or fewer to rely on (OR = 5.83, 95% CI = [1.62, 21.01], p = 0.01). PTSD was more likely in those with a negative media experience ( n = 34/52, 65.4%, OR = 11.90, 95% CI = [1.42, 100.04], p = 0.02) and 61.5% ( n = 32/52) of respondents reported media coverage lasting months or years. In multivariate modelling, negative media impact, relationship status and friendships were independently associated with PTSD and explained much of the variance in PTSD ( F4,41 = 10.94, p < 0.0001, r2 = 0.52). CONCLUSION: Nearly one-third of members of an Australian shark-bite peer-support group report post-event PTSD, and one-quarter of these were not present at the time of the event. Findings support interventions targeting negative media impact, similar to media reporting guidelines for suicide, and enhancing social support.

A quick assessment tool for human-directed aggression in pet dogs.

Many test series have been developed to assess dog temperament and aggressive behavior, but most of them have been criticized for their relatively low predictive validity or being too long, stressful, and/or problematic to carry out. We aimed to develop a short and effective series of tests that corresponds with (a) the dog's bite history, and (b) owner evaluation of the dog's aggressive tendencies. Seventy-three pet dogs were divided into three groups by their biting history; non-biter, bit once, and multiple biter. All dogs were exposed to a short test series modeling five real-life situations: friendly greeting, take away bone, threatening approach, tug-of-war, and roll over. We found strong correlations between the in-test behavior and owner reports of dogs' aggressive tendencies towards strangers; however, the test results did not mirror the reported owner-directed aggressive tendencies. Three test situations (friendly greeting, take-away bone, threatening approach) proved to be effective in evoking specific behavioral differences according to dog biting history. Non-biters differed from biters, and there were also specific differences related to aggression and fear between the two biter groups. When a subsample of dogs was retested, the test revealed consistent results over time. We suggest that our test is adequate for a quick, general assessment of human-directed aggression in dogs, particularly to evaluate their tendency for aggressive behaviors towards strangers. Identifying important behavioral indicators of aggressive tendencies, this test can serve as a useful tool to study the genetic or neural correlates of human-directed aggression in dogs.

The neurocognitive effects of simulated use-of-force scenarios.

While the physiologic effects of modern conducted electrical weapons (CEW) have been the subject of numerous studies, their effects on neurocognitive functioning, both short-term and long-term, are less well understood. It is also unclear how these effects compare to other use-of-force options or other arrest-related stressors. We compared the neurocognitive effects of an exposure to a TASER(®) (TASER International, Inc, Scottsdale, AZ) X26™ CEW to four other use-of-force scenarios during a training exercise using a well-established neurocognitive metric administered repeatedly over 1 h. Overall, we found that there was a decline in neurocognitive performance immediately post-scenario in all groups, but this effect was transient, of questionable clinical significance, and returned to baseline by 1 h post-scenario.

Review of psychological effects of dog bites in children.

BACKGROUND: Dog bites are a concerning health problem in children and one of the leading causes of non-fatal injuries in this population. Dog attacks not only cause physical injuries but can also lead to long-term psychological problems. A review was performed to investigate the scope of literature on the psychological effects of dog bites on a paediatric population. METHODS: A literature search was performed on Web of Knowledge database between 1982 to June 2023, returning 249 results. 14 primary studies reporting the psychological consequences of dog bites in children or adolescents were classed as eligible and 9 further studies were added from prior knowledge and bibliographical searches. 23 studies involving 1894 participants met the criteria and were included in this review. RESULTS: Of these 23 studies, 8 were case studies or small case series reports (up to n=4), 14 larger descriptive studies and 1 analytical cross-sectional study. There was a mixture of retrospective and prospective data-gathering. The most common psychological consequences of dog bites in children were post-traumatic stress disorder, dog phobia, nightmares and symptoms of anxiety and avoidance behaviours. CONCLUSIONS: Studies on dog bites in a paediatric population with a specific focus on the psychological consequences associated with dog bites and their management are sparse. Future research and practice should more greatly consider the psychological impact on child victims of dog bites and their family members, as well as their management to avoid the development of mental health issues and improve their quality of life. Future research also needs to ascertain the efficacy of using virtual reality in treating children with dog phobia.

Identifying youth at risk for difficulties following a traumatic event: pre-event factors are associated with acute symptomatology.

This study examined factors related to children's acute symptoms following a potentially traumatic event (PTE) to more clearly identify domains that should be included in screenings of youth exposed to a PTE. In particular, the authors examined whether trauma category (i.e., sexual abuse/disclosure of abuse, intentionally perpetrated traumas other than sexual abuse, and unintentional traumas) was related to symptoms after controlling for other relevant factors. Participants were 112 youth presenting for clinical evaluation within a month of a PTE and their nonoffending caregivers. Using data from baseline assessments collected as part of a randomized controlled trial of a secondary prevention program, the following factors were tested in 3 hierarchical regression models: index PTE category, history of traumatic exposure, preindex event functioning, and parenting behaviors. Prior trauma exposure, preindex event functioning, and hostile parenting were uniquely related to children's symptoms in the acute posttraumatic period after controlling for time since the event and child age, but trauma category was not. Implications for identifying and referring children at high risk for poor outcomes in the early aftermath of a PTE are discussed. An exclusive focus on the event is insufficient and more comprehensive understanding of the child and family is required.

Perceptions and treatment seeking behavior for dog bites in rural Bangladesh.

We conducted a study of the knowledge, attitudes and practices regarding dog bites among residents of a rural community in Bangladesh from September 2006 to February 2007 using face to face interviews with 1,973 adults from five villages. The mean age of the respondents was 34+/-16 years. Sixty-eight percent of subjects were female, 7.3% of respondents reported a history of dog bite in a family member; 10% had been bitten twice. Sixty-five percent of subjects were aware of rabies and 99.1% knew a dog bite was the cause of rabies. Seventy-one percent of subjects were aware of a rabies vaccine, 77.5% of respondents stated rabies can cause death. Ninty percent of dog bite victims received treatment by traditional healers, 25% were treated with a rabies vaccine and 2.1% of victims died. Greater awareness is needed in rural Bangladesh regarding prevention of rabies.

[Conflict coping strategies in patients with somatoform disorders]. / Konfliktbewältigungsstrategien bei Patienten mit somatoformen Störungen.

245 patients presenting with allergic complaints were interviewed with SCID for the diagnosis of a somatoform disorder and filled in the "ques-tionnaire of conflict coping strategies (FKBS)" 55 patients with insect allergy and 100 depressed patients served as controls. Only depressed patients diverged from the FKBS reference scores, particularly with respect to "turning against self".

Early Hypnotic Intervention After Traumatic Events in Children.

Post-traumatic stress disorder is a debilitating condition that can develop after exposure to any potentially traumatic event (natural disaster, physical assault, and car accident). This study focused on four pediatric patients presenting with an early stress response after a motor vehicle accident who were offered early therapeutic and a preventive management by hypnotherapy shortly after exposure to the traumatic event. All patients improved after one or several sessions of hypnosis. The results indicate that hypnotherapy can immediately help patients during the early period following a traumatic event.

Brief report: Don't kiss a sleeping dog: the first assessment of "the blue dog" bite prevention program.

OBJECTIVE: The authors attempted to remedy the current lack of empirically evaluated dog-bite prevention programs for children under 7 by assessing children's learning success with the "Blue Dog" CD. METHODS: Ninety-six 3-, 4-, 5-, and 6-year-old children used the interactive CD in an initial exposure phase, a training and a testing phase. Half received verbal feedback, and the other half additional practice with parents. All children were re-tested after 2 weeks. RESULTS: There were significant increases in safe choices after the training phase at all ages, with older children performing better than younger children. Children still retained their ability to make safe choices after 2 weeks. Interestingly, children practicing with parents performed better than others when under 6 years. Verbal feedback did not play a role, the CD is equally effective without. CONCLUSIONS: Children learned successfully about safe behavior with dogs; thus, the CD can help educate children about dog-bite prevention.

The impact of companion animal problems on society and the role of veterinarians.

The benefits of companion animals are immense, but there can be negative impacts also. Noise, destructive behaviors, excrement, bites, and the overpopulation of domestic cats and dogs are some of the major problems that can result in stress and hardships on owners, neighbors, the community, and the pets themselves. The perpetuation of pets in society requires that the negative aspects of living with dogs and cats be addressed. Veterinarians can play an important role in addressing these problems by incorporating the concept of behavior wellness into their practices and promoting education regarding husbandry, animal behavior, responsible pet ownership, and the effects of pets on the environment.

Scoping decades of dog evidence: a scoping review of dog bite-related sequelae.

OBJECTIVES: There has been considerable literature published focusing on various sequelae to dog bites over the last three decades. Much of the literature has focused on rabies, particularly canine rabies variant, which accounts for the majority of rabies deaths worldwide. This paper describes the complications, the pathogens, and other sequelae resulting from dog bites documented in the literature. METHODS: This paper used evidence found through a scoping review which charted the published peer-reviewed and non-peer-reviewed gray literature and online information relating to dog bite incidents. Each complication or sequela was additionally assessed from the viewpoint of Canadian Indigenous, rural, and geographically remote communities, which experience a high number of dog bite incidents annually. SYNTHESIS: Peer-reviewed literature (N = 693; case report, original research, and review articles) provided detailed information on specific pathogens, infections, and diseases of interest, especially rabies. However, in addition to these, the sequelae from dog bites may include moderate to severe injuries that further result in anxiety around dogs or post-traumatic stress disorder (PTSD). CONCLUSIONS: While a lot of focus in the literature is on rabies as a sequela to dog bites, the impacts of anxiety and PTSD are not as well articulated. Treatment of dog bite injuries may be standardized; however, improved collaborations between diverse health professionals (physicians, veterinarians, counseling services, animal behaviourists, and others) could be of considerable benefit in decreasing the effects of dog bites.

The adaptive value of tool-aided defense against wild animal attacks.

Throughout history humans have faced the persistent threat of attacks by wild animals, and how humans respond to this problem can make the difference between survival and death. In theory, the use of tools to fend off animal attacks would be more effective than resisting bare-handed, yet evidence for the advantage of tool-aided defense is scarce and equivocal. Two studies of news accounts of wild animal attacks against humans were conducted to test the hypothesis that tool-aided defense is indeed associated with reductions in injuries and deaths. Results of both Study 1 (N=172) and Study 2 (N=370) supported the hypothesis. The observed survival advantage of tool-aided defense for modern humans suggests that this tactic also would have worked for human ancestors who lived more closely to dangerous wild animals.

Effects of gender and parental status on knowledge and attitudes of dog owners regarding dog aggression toward children.

OBJECTIVE: To assess the effects of gender and parental status of dog owners on knowledge of and attitudes toward factors associated with dog aggression directed toward children. DESIGN: Prevalence survey. POPULATION: 804 dog owners. PROCEDURES: A questionnaire was distributed to owners of all dogs examined at a university veterinary hospital between January and April 2007. Respondents were asked to indicate whether they agreed or disagreed with 37 statements regarding dog behavior and safety practices for dog-child interactions. Responses were compared between women and men and between parents and nonparents. RESULTS: Of 804 questionnaires that were completed, 421 (52%) were completed by parents and 598 (74%) were completed by women. There was a general lack of knowledge regarding dog behavior and safety practices for dog-child interactions. Women were more knowledgeable than men, regardless of parental status. Mothers were more knowledgeable than fathers and female nonparents regarding interactions with young children and had greater awareness than female nonparents and males (regardless of parental status) regarding interactions with infants and toddlers. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that dog owners frequently had only limited knowledge of dog behavior and often were unaware of factors that increased the risk of dog bites to children. The veterinary examination presents an important opportunity for education of dog owners regarding dog behavior, including body language, social signals, resource-guarding, and self-defense, and the risks of dog bites to infants and young children.

Characteristics of 234 dog bite incidents in Ireland during 2004 and 2005.

Information was obtained by telephone interview from 100 dog owners whose dog had bitten a person, and from 134 victims of bites by a dog not owned by the victim. Three-quarters of the victims were female and aged from 21 to 60 years. The majority of the dogs were owned, male, two to six years old, over 10 kg in bodyweight and belonged to the popular breeds: collies, cocker/springer spaniels, terrier breeds, Jack Russell terriers, German shepherd dogs, golden retrievers and crossbreeds. The numbers of bites by the different breeds indicated that those that inflicted the most bites were the popular breeds rather than the breeds with any greater propensity to bite. Most attacks were rapid single bites and in 50 per cent of the cases, neither the owner nor the victim was able to identify any signal of the dog's intention to bite. Overall, 21 per cent of the incidents were rated as 'serious' and 2 per cent as 'life threatening'. One fifth of the dogs were euthanased as a result of the incident. Half the incidents required professional medical assistance for the victim. Almost half the incidents took place while the victim was walking or passing close to the dog's territory, or while the victim was interacting with the dog at home.

Outcome survey of insect venom allergic patients with venom immunotherapy in a rural population.

BACKGROUND: Hymenoptera venom anaphylaxis is a frightening event that affects physical and psychical functioning. PATIENTS AND METHODS: Retrospective survey of 182 Hymenoptera venom allergic patients living in a rural area using a questionnaire targeting on patients' satisfaction during therapy, fear of anaphylactic recurrences and changes in lifestyle before and after venom immunotherapy (VIT). Additionally, patients' self-assessment of quality of life, daily outdoor time and re-sting rate were recorded. RESULTS: 146 patients returned the questionnaire (58.9% male, 41.1% female, 25.3% honey bee allergic, 67.8% wasp allergic, 41.1% re-sting rate, mean follow-up time 6.5 years). Measurement of the parameters fear, satisfaction and changes in lifestyle revealed a significant improvement after VIT. This correlated with the patients'self-assessment of quality of life,when 89.7% declared an improvement after VIT. Although the improvement was higher in patients with re-stings, also patients without re-stings clearly benefited from VIT. Interestingly, females were significantly more affected by Hymenoptera venom allergy than males,whereas both genders showed a similar improvement after VIT. CONCLUSIONS: Patients with Hymenoptera venom sting allergy significantly benefit from VIT in regard to both biological and psychological outcome. VIT should still be provided to all Hymenoptera venom allergic patients as standard of care.

Defaming Rover: Error-Based Latent Rhetoric in the Medical Literature on Dog Bites.

This article examines the accuracy and rhetoric of reports by human health care professionals concerning dog bite injuries published in the peer-reviewed medical literature, with respect to nonclinical issues, such as dog behavior. A qualitative content analysis examined 156 publications between 1966 and 2015 identified by terms such as "dog bite" or "dangerous dogs." The analysis revealed misinformation about human-canine interactions, the significance of breed and breed characteristics, and the frequency of dog bite-related injuries. Misinformation included clear-cut factual errors, misinterpretations, omissions, emotionally loaded language, and exaggerations based on misunderstood or inaccurate statistics or reliance on the interpretation by third parties of other authors' meaning. These errors clustered within one or more rhetorical devices including generalization, catastrophization, demonization, and negative differentiation. By constructing the issue as a social problem, these distortions and errors, and the rhetorical devices supporting them, mischaracterize dogs and overstate the actual risk of dog bites.
