The Effect of an Animal-Assisted Intervention on Anxiety and Pain in Hospitalized Children

ABSTRACT

Forty children between the ages of 8 and 18 years, who were admitted to a hospital pediatric unit, were randomly assigned to an animal-assisted intervention (AAI) or an active control condition (working on an age-appropriate jigsaw puzzle). Ratings of pain and anxiety were taken both pre- and post-condition. The attachment Questionnaire and Family Life Space Diagram (FLSD) also were administered, and information on medications taken was recorded. A significant post-condition difference was found between groups for anxiety, with the aaI group having lower anxiety scores. However, no significant within- or between-group pre-post changes in either pain or anxiety were detected. Nearly two-thirds of the children (64%) reporting pain at baseline were receiving some type of analgesic, which may have influenced outcomes. Findings demonstrate some support that attachment may be a moderating variable: children with a secure attachment style reported lower pain and anxiety at baseline, with large effect sizes for differences in both anxiety (g = 1.34) and pain (g = 1.23). Although the aaI did not significantly reduce anxiety and pain in these hospitalized children, further investigation of the influence of analgesic use and the moderating effect of attachment style is indicated.     

The Presence of a Therapy Dog Results in Improved Object Recognition Performance in Preschool Children

ABSTRACT

The purpose of this study was to determine whether the presence of a dog would have an impact on object recognition memory performance of preschool children. This work represents an extension of previous research which found that preschoolers require fewer instructional prompts to complete this type of memory task when in the presence of a dog. If children require fewer instructional prompts it is possible that they are better able to focus on the task itself and as a result, improved memory performance is likely. Because the earlier experiment utilized a very simple version of the task that was readily completed by the preschool children, the overall performance data were at ceiling. The current study, involving 20 preschool children, included a manipulation of task difficulty through varying the number of distracters (one versus four) present at test. Increasing the number of distractors in a simple recognition task is known to make that task more challenging, and thus performance was expected to be slower and less accurate in the four distracter conditions relative to the one-distracter conditions. The collaborators in the study were either a therapy dog or a human. A two-way repeated measures design was used such that each child served as his/her own control and was tested in each of four separate conditions: dog present (one and four distracters) and human present (one and four distracters). The results showed that the preschool children performed the object recognition task faster and more accurately in the presence of the therapy dog relative to a human and also in the one-distracter versus four-distracter condition. The authors conclude that these effects result from increased focus and/or motivation resulting from the presence of the dog.     

News & Analyses

ABSTRACT

The purpose of this study was to examine preschoolers' (n = 11) ability to follow instructions in the presence or absence of a real dog while executing a variety of motor skills tasks. These tasks were divided into one of three general classifications: 1) Modeling Tasks: the children were asked to emulate the behavior of a model, 2) Competition Tasks: the children were asked to do the task faster than a competitor, and 3) Tandem Tasks: the children were asked to do the tasks at the same time as a co-performer. Typical and Identified (language impaired) preschool children were randomly assigned to perform five tasks of each general classification alone, with a human, with a real dog, and with a stuffed dog that was similar in size and appearance to the live dog. Two independent raters rated each child's adherence to instructions (interrater reliability = 0.99) on a 7-point scale. A significant interaction between task classification and type of co-performer revealed that in the Modeling Tasks the preschoolers adhered better to the instructions when the real dog was present relative to the other conditions. In the Tandem Tasks the children adhered to instructions best when they performed the task with a human, followed by the stuffed dog (as manipulated by a human), the real dog, and worst when they were asked to perform the tasks alone. The type of co-performer made no significant difference in the Competition Tasks. These results indicate the presence of a real dog tends to be beneficial for promoting preschoolers' compliance with instructions in motor skills tasks that require modeling behavior, but not in those tasks that stress competition or those performed in tandem.     

Methodological issues in studying the anxiety-reducing effects of animals: Reflections from a pediatric dental study

Abstract

This article reports observations made during a study investigating the role of a therapy dog in reducing anxiety in urban children visiting the dentist. The design and execution of the study were affected by methodological issues such as the reaction of urban children to the dog in the clinic, the tools used to measure anxiety in the children, the age and pet-ownership status of the children, and the personality of the therapy dog. Suggestions made for researchers designing similar studies include allowing children to become comfortable with the therapy dog before beginning formal data collection, working with younger children who have made fewer visits to the dentist, and using or developing more accurate tools for measuring behavioral and physiological anxiety.     

Nursing Home Staffs' Empathy for a Missing Therapy Dog,their Attitudes to Animal-Assisted Therapy Programs and Suitable Dog Breeds

ABSTRACT

The study was conducted at the Returned Soldiers League (RSL) War Veterans Home at Pinjarra Hills (Brisbane, Queensland, Australia) where a spayed female Whippet, Heidi, was placed as a therapy dog. Of the 80 staff members, 47 (58.75%) returned completed questionnaires on attitudes towards Animal-Assisted Therapy (AAT) programs and the disappearance of Heidi two days after placement. The Pet Attitude Scale (Templer et al. 1981) was used in conjunction with the staff attitude questionnaire.

Respondents with high Pet Attitude scores were more upset (χ²₍₂₎=8.41, p<0.05) and liked dogs more (χ²₍₂₎=7.03, p<0.05) than staff with medium or low scores. The staff with high scores were also more pleased when Heidi returned (χ²₍₁₎=15.97, p<0.05). Respondents who wanted a program were those who liked dogs the most (χ²₍₁₎=7.02, p<0.05) and did not think having an AAT program would increase their workload (χ²₍₁₎=3.77, p<0.05). Staff who thought a dog should live at the nursing home were pleased (χ²₍₁₎=5.2, p<0.05) when Heidi returned.

Gentle/placid dogs were more frequently chosen (78.7%) than active dogs as suitable for AAT and the preferred size was medium (57.5%) with a short coat (78.7%).

Preschoolers Categorize Animate Objects Better in the Presence of a Dog

ABSTRACT

The current study was designed to examine whether preschool children categorize picture stimuli differentially in the presence of a real dog compared with a stuffed dog or a human. Seventeen preschool children (age in months; M = 51.67, SD = 8.06), both Typical and those with a developmental delay (“Identified”), were asked to categorize Animate and Inanimate objects into two environments (Farm and Ocean) in each of three Collaborator conditions (Real Dog, Stuffed Dog, and Human). As predicted, there was a main effect of animation: the children more accurately categorized Animate (e.g., cow) exemplars than Inanimate ones (e.g., tractor). Additionally, the Animation variable interacted with Collaborator, such that in the presence of the real dog the impact of animation was significant, but this effect was not significant in the presence of the stuffed dog or human. This result indicates that the presence of the real dog served as a highly salient stimulus which encouraged the children to focus more of their attention on other animate objects in the list. This result provides additional evidence that the presence of a dog helps preschool children to restrict their attention to the demands of the task. This is a new and interesting finding that indicates that the presence of a real dog does have an impact on cognitive task performance.

Functional Near Infrared Spectroscopy of the Sensory and Motor Brain Regions with Simultaneous Kinematic and EMG Monitoring During Motor Tasks

There are several advantages that functional near-infrared spectroscopy (fNIRS) presents in the study of the neural control of human movement. It is relatively flexible with respect to participant positioning and allows for some head movements during tasks. Additionally, it is inexpensive, light weight, and portable, with very few contraindications to its use. This presents a unique opportunity to study functional brain activity during motor tasks in individuals who are typically developing, as well as those with movement disorders, such as cerebral palsy. An additional consideration when studying movement disorders, however, is the quality of actual movements performed and the potential for additional, unintended movements. Therefore, concurrent monitoring of both blood flow changes in the brain and actual movements of the body during testing is required for appropriate interpretation of fNIRS results. Here, we show a protocol for the combination of fNIRS with muscle and kinematic monitoring during motor tasks. We explore gait, a unilateral multi-joint movement (cycling), and two unilateral single-joint movements (isolated ankle dorsiflexion, and isolated hand squeezing). The techniques presented can be useful in studying both typical and atypical motor control, and can be modified to investigate a broad range of tasks and scientific questions.     

Prevalence of Enterobius vermicularis among Preschool Children in Muan-gun, Jeollanam-do, Korea

We assessed the prevalence of Enterobius vermicularis infection and changes in the egg positive rate (EPR) over 1-year time, using the adhesive cellophane-tape perianal swab method in 2,347 preschool children in Muan-gun, Jeollanam-do, Republic of Korea in 2008 and 2009. The overall EPR for E. vermicularis was 4.1% in 2008 and 4.5% in 2009. A study population of 389 children was repeatedly examined for 2 years. Within this group, the EPR in 2009 was twice higher than in 2008, and the EPR of the group of 5-7-year-old children was significantly higher than that of other age groups. Moreover, in the group of 5-7-year-old children in 2009, the rates of positive and negative conversion were significantly higher and lower, respectively, than in other age groups. Conclusively, enterobiasis was prevalent during 2008-2009 among preschool children in Muan-gun, Jeollanam-do, and the increased EPR in 2009 was due to an increase in newly acquired infections among 5-7-year-old children.     

Preference for,and Responsiveness to,People, Dogs and Objects in Children with Autism

ABSTRACT

Autism strongly affects the ability to establish social interactions. However, there is some suggestion that people with autism establish close social relationships with nonverbal communicating and intentionally acting animals (such as dogs). In this study, 14 children with autism (3 females, 11 males; mean age = 11.4 years) were observed when given the choice to interact with a person, dog (certified therapy dog) or objects (e.g., toys). The children interacted most frequently and for longest with the dog, followed by the person and then the objects. We suggest that animals, specifically dogs, communicate their intentions in a way more readily understandable to people with autism. We also suggest that autism affects predominantly interpersonal interactions.     

Prevalence of Enterobius vermicularis Infection among Preschool Children in Kindergartens of Taipei City, Taiwan in 2008

The prevalence of Enterobius vermicularis infection among preschool children was reported to be low based on a 5-year screening program in Taipei City, Taiwan. The Taipei City government intended to terminate the E. vermicularis screening program among preschool children. Thus, we were entrusted with confirming whether pinworm infections among preschool children in Taipei City had truly declined. From each of 12 administrative districts 2-3 kindergartens were randomly selected for investigation. In total, 4,349 children were examined, of which 2,537 were boys and 1,812 were girls. The cellophane tape adhered to a glass slide was used, and all examinations were done by certified medical technologists. Results indicated that the overall prevalence rate of pinworm infections was 0.62% (27/4,349). Although the infection rate was higher among boys (0.67%, 17/2,537) than in girls (0.55%, 10/1,812), no significant difference was found (χ² = 0.399, P = 0.62). According to the administrative district, the infection rate ranged from no positive cases of E. vermicularis infection in the Xinyi, Zhongzhen, and Wanhua Districts (0%; 0/299, 0/165, and 0/358, respectively), to 0.26% (1/131) in Songshan District, with the highest rate of 1.88% (7/373) in Wenshan District. Because the overall infection rate (0.62%, 27/4,349) in the present study was unchanged compared to that (0.40%, 197/49,541) previously reported in 2005, we propose that regular pinworm screening and treatment programs should be continued in some parts of Taipei City.     

The effects of the presence of a dog in the classroom

Abstract

This study examined the effects of the presence of a dog in the classroom on field independence, social competence, empathy with animals and social-emotional atmosphere. The participants were 46 first-graders (43 of them immigrants) of two school classes (control and experimental). In the experimental group, a dog was present in the classroom for three months. Multivariate analyses revealed significant enhancement of field independence and empathy with animals in the experimental group in comparison to the control group (no dog). Thus, the presence of the dog fostered the development of autonomous functioning and a better segregation of self/non-self, which is the foundation of sensitivity towards the needs and moods of other people. Moreover, according to the views of the teachers, the children in the experimental group exhibited higher social integration, and there were fewer aggressive children, compared with the children in the control group. In sum, the results indicate that a dog can be an important factor in the social and cognitive development of children.     

The effects of group and individual animal-assisted therapy on loneliness in residents of long-term care facilities

Abstract

Animal-assisted therapy (AAT) has been shown to reduce the loneliness of residents in long-term care facilities (LTCFs). In this study, we determined the relative contribution of socialization (human–human bonding) and human–animal bonding as mechanisms by which AAT reduces loneliness. Residents in LTCFs volunteering for AAT were randomized to receive AAT as individuals (Individual) or in groups of two to four (Group). Individual AAT was used as a measure of animal–human bonding, and Group AAT was used as a measure of the combination of animal–human bonding and socialization. Any greater effect of Group AAT in comparison to Individual AAT would be ascribed to socialization. Thirty-seven residents of LTCFs, who were cognitively intact, volunteered for AAT, and scored as significantly lonely on the UCLA Loneliness Scale (Version 3), were studied. Six weeks of AAT, one 30-minute session per week, in an individual or group setting was performed, with posttesting during week five. Two residents dropped out of each group, giving us group sizes of 17 (Individual) and 16 (Group). A two-way ANOVA showed a statistically significant effect of pretest vs. posttest scores (F_(1,31) = 25.3, p < 0.001), with no effect of Group vs. Individual or of interaction. Newman Keuls post-hoc tests showed that the pretest scores for Individual and Group participants did not differ. There was a significant difference between pretest and posttest scores for Individual participants (p < 0.05) but not for Group participants. There was no difference between the posttest values for Individual vs. Group. When the data from all 33 participants were combined, Delta scores (pretest minus posttest), correlated positively (p < 0.01) with pretest scores, showing that lonelier individuals benefited more from AAT. In conclusion, AAT was more effective in improving loneliness in residents of LTCFs when given individually than in a group situation. Therefore, the main effect of AAT was not mediated by socialization.     

Evaluation of Two Triple‐Therapy Regimens with Metronidazole or Clarithromycin for the Eradication of H. pylori Infection in Vietnamese Children: a Randomized,Double‐Blind Clinical Trial

Background: Eradication of Helicobacter pylori infection in children in developing countries needs further investigations upon which to base treatment recommendations. The aim of the study was to compare two 2‐week triple therapies in a randomized double‐blind trial. Materials and Methods: In order not to exceed recommended dosages, the 238 H. pylori‐infected children, aged 3 to 15 years (mean 8.6), were divided in two weight categories receiving at weights 13–22 kg: lansoprazole 15 mg once‐daily and amoxicillin 500 mg twice‐daily with metronidazole 250 mg twice‐daily or clarithromycin 250 mg once‐daily; at weights 23–45 kg: lansoprazole 15 mg and amoxicillin 750 mg with metronidazole 500 mg or clarithromycin 250 mg, all administered twice daily. H. pylori status was assessed by culture and a monoclonal‐based antigen‐in‐stool test (Premier Platinum HpSA PLUS) and side effects by structured questionnaires. Results: The overall per‐protocol eradication (n = 233) was similar in the two treatment regimens, 62.1% for the metronidazole and 54.7% for the clarithomycin‐containing therapy. Eradication rate was higher in children ≥ 23 kg (70.9%) than in children < 23 kg (45.7%). In children ≥ 23 kg (n = 117) that received twice‐daily administration of all drugs, efficacy of the methronidazole and clarithromycin‐containing treatments were 69.5% and 72.4%, respectively. Conclusions: The two treatments gave similar eradication rates. Significant differences for both treatments were found by weight, which could be the result of the once‐daily proton pump inhibitor and clarithromycin and/or more antibiotic resistant strains in younger children.

The Role of Biomarkers for Diagnosis of and Therapeutic Decisions Related to Invasive Aspergillosis in Children

Invasive aspergillosis (IA) is a feared opportunistic infection for many immuncompromised children resulting in significant morbidity and mortality. Timely diagnosis based on traditional testing modalities and clinical evaluation has proven to be challenging. Assays designed to measure IA biomarkers such as galactomannan (GM) and beta-D-glucan (BG) represent a potential significant improvement in the ability to diagnose pediatric IA. However, as with any new diagnostic tool, clinicians need to be aware of the operating characteristics of these assays in order to apply them in the appropriate settings. Published adult and pediatric data regarding GM and BG testing are reviewed and guidance regarding the appropriate utility of these assays in children is offered.     

A Dual Role for the Zebrafish unplugged Gene in Motor Axon Pathfinding and Pharyngeal Development

On their way toward their synaptic targets, motor growth cones encounter multiple choice points, where they are confronted with trajectory choices. We have previously shown that the zebrafish unplugged gene acts as a somite-derived cue controlling pathway choice of primary motor axons. Here, we demonstrate that this trajectory choice is not exclusively controlled by a single unplugged-dependent process, but depends on the coordinated function of additional cues. We also show that secondary motor neurons, most similar to those in birds and mammals, depend on the unplugged gene to navigate a choice point, suggesting that primary and secondary motor neurons share common mechanisms controlling axonal path selection. Moreover, we show that the unplugged gene plays an additional role guiding secondary motor axons through a single segmental nerve. Finally, we report that unplugged larvae display a striking pharyngeal arch defect, consistent with a dual function of the unplugged gene in axonal guidance and cell motility.     

The Role of Phosphometabolites in Cell Proliferation, Energy Metabolism, and Tumor Therapy

A common characteristic of tumor cells is the constant overexpression of glycolytic and glutaminolytic enzymes. In tumor cells the hyperactive hexokinase and the partly inactive pyruvate kinase lead to an expansion of all phosphometabolites from glucose 6-phosphate to phosphoenolpyruvate. In addition to the glycolytic phosphometabolites, synthesis of their metabolic derivatives such as P-ribose-PP, NADH, NADPH, UTP, CTP, and UDP-N-acetyl glucosamine is also enhanced during cell proliferation. Another phosphometabolite derived from P-ribose-PP, AMP, inhibits cell proliferation. The accumulation of AMP inhibits both P-ribose-PP-synthetase and the increase in concentration of phosphometabolites derived from P-ribose-PP. In cells with low glycerol 3-phosphate and malate-aspartate shuttle capacities the inhibition of the lactate dehydrogenase by low NADH levels leads to an inhibition of glycolytic ATP production. Several tumor-therapeutic drugs reduce NAD and NADH levels, thereby inhibiting glycolytic energy production. The role of AMP, NADH, and NADPH levels in the success of chemotherapeutic treatment is discussed.
