Effect of Equine-Assisted Activities on Cardiac Autonomic Function in Children with Cerebral Palsy: A Pilot Randomized-Controlled Trial

From biology to the clinic - exploring liver metastasis in prostate cancer

Liver metastases from prostate cancer are associated with an aggressive disease course and poor prognosis. Results from autopsy studies indicate a liver metastasis prevalence of up to 25% in patients with advanced prostate cancer. Population data estimate that ~3-10% of patients with metastatic castration-resistant prostate cancer harbour liver metastases at the baseline, rising to 20-30% in post-treatment cohorts, suggesting that selective pressure imposed by novel therapies might promote metastatic spread to the liver. Liver metastases are associated with more aggressive tumour biology than lung metastases. Molecular profiling of liver lesions showed an enrichment of low androgen receptor, neuroendocrine phenotypes and high genomic instability. Despite advancements in molecular imaging modalities such as prostate-specific membrane antigen PET-CT, and liquid biopsy markers such as circulating tumour DNA, early detection of liver metastases from prostate cancer remains challenging, as both approaches are hampered by false positive and false negative results, impeding the accurate identification of early liver lesions. Current therapeutic strategies showed limited efficacy in this patient population. Emerging targeted radionuclide therapies, metastasis-directed therapy, and novel systemic agents have shown preliminary activity against liver metastases, but require further validation. Treatment with various novel prostate cancer therapies might lead to an increase in the prevalence of liver metastasis, underscoring the urgent need for coordinated efforts across preclinical and clinical researchers to improve characterization, monitoring, and management of liver metastases from prostate cancer. Elucidating molecular drivers of liver tropism and interactions with the liver microenvironment might ultimately help to identify actionable targets to enhance survival in this high-risk patient group.

The role of animal-assisted programs in physical health improvement of children and adolescents with special education needs - a systematic review

Programs involving animals in therapeutic programs are becoming increasingly prevalent. These programs can vary greatly in their approach, scope, and objectives, and they can significantly impact the development of healthy children and those with various disorders. In this systematic review, we sought to investigate the psychological ramifications of animal-assisted activities (AAA), therapies (AAT), and interventions (AAI). We searched for relevant studies using the EBSCO Discovery Service search engine across 85 databases, utilising appropriate keywords. Our search generated 262 results, of which 21 were selected for inclusion after title and abstract screening, as well as full-text analysis. Our findings indicate that dogs and horses are animal-assisted programs' most commonly used animals. Additionally, autism, cerebral palsy, and ADHD were found to be overrepresented in these programs. Furthermore, the length of sessions and overall program duration exhibited considerable variation, regardless of patient age or disease type. The principal measures centred on the physiological variables related to the nervous system and motorium-related indicators. The studies were generally of exceptional methodological soundness. Frequently, the studies narrowed their scope to a single segment or just the child or adolescent, but the outcomes lacked contextual interpretation. Expanding the range of studies by comparing psychological and physiological indicators and conducting follow-up analysis with a longitudinal design would be beneficial.

Effect of the Sway Bed on Autonomic Response, Emotional Responses, and Muscle Stiffness in Children with Severe Motor and Intellectual Disabilities: A Pilot Study

This cross-sectional study aimed to examine the effects of being swayed in a sway bed on children with severe motor and intellectual difficulties by examining potential differences in their autonomic and emotional responses, as well as their muscle hardness, and by comparing them with “a control condition without any stimulation”. Children’s heart rate variability, rectus femoris hardness, and passive hip abduction range of motion (ROM) were measured in two experimental conditions, differentiated by the presence of a 5-min sway stimulus. In each condition, the children’s faces were video-recorded and retrospectively rated subjectively by their homeroom teacher concerning the visible expression of eight emotions. Significant intervention-related effects were observed on the heart rate variability and the “Relax” item of the emotional response indicators but not on muscle hardness or hip ROM. Our findings provide evidence that using a motorized sway bed can promote relaxation in children with severe motor and intellectual disabilities by influencing their autonomic response.

Does Hippotherapy Improve the Functions in Children with Cerebral Palsy? Systematic Review Based on the International Classification of Functioning

Objective: To perform a systematic review of the literature regarding scientific reality of hippotherapy in children with cerebral palsy graded according to France HAS (Haute Autorité de Santé) recommendations and applied to the International Classification of Functioning. Methods: The research in MEDLINE and Cochrane Library databases was performed using the keywords: "Equestrian therapy," "Riding for the disabled," "Hippotherapy," "Equine-movement therapy," and "Therapeutic horse (back) riding." The methodological quality of the articles was assessed using four levels of proof and three guideline grades (A: strong; B: moderate; C: poor). Results: Seven prospective, randomized controlled studies and one systematic review confirm the level of proof of hippotherapy in children with cerebral palsy with grade B. Hippotherapy in children with cerebral palsy contributes to improve motor function, symmetry of muscle contraction, spasticity, posture, and walking. Fifty prospective no randomized studies confirm the level with grade C for balance, motor coordination, lumbopelvic mobility, walking speed, functional development, and social behavior. Conclusions: Hippotherapy in children with cerebral palsy can be recommended. Regarding the literature data, the level of proof of hippotherapy in children with cerebral palsy is moderate (grade B).

Equine-Assisted Therapies for Children With Cerebral Palsy: A Meta-analysis

CONTEXT

Equine-assisted therapy in different facets aims to improve the clinical condition of children with cerebral palsy. A more comprehensive overview on the overall effects and on the differences between different treatment modalities seems desirable.

OBJECTIVE

We compared the effectiveness of various equine-assisted treatments on motor capabilities and quality of life of children with cerebral palsy.

DATA SOURCES

We conducted systematic searches of PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials.

STUDY SELECTION

Randomized and nonrandomized controlled parallel-group or crossover studies on equine-assisted therapies in comparison with standard of care were included.

DATA EXTRACTION

Data on motor function assessed by different instruments were considered as the primary outcome. Secondary outcomes included global, social, physical, and emotional scores of quality of life.

RESULTS

Strong evidence for a positive effect of equine-assisted therapies, particularly hippotherapy, on global gross motor function and motor capabilities during walking in children with cerebral palsy was identified (SMD 0.24, 95% CI 0.05 to 0.43, P = .01, t2 = 0.00, I2 = 15%; SMD 2.68, 95% CI 1.02 to 4.34, P = .002, t2 = 0.0, I2 = 0%). No evidence for the improvement in quality of life could be shown in the global assessment, nor in any subscore.

CONCLUSIONS

Equine-assisted therapy, particularly hippotherapy, can be a therapeutic tool for children who are learning to walk.

LIMITATION

The heterogeneity of tools used in different studies and the low number of studies addressing quality of life issues limited the number of studies available for distinct analyses.

Effect of Equine-Assisted Activities and Therapies on Cardiorespiratory Fitness in Children with Cerebral Palsy: A Randomized Controlled Trial

Abstract Objectives: To determine the effects of an equine-assisted activities and therapies (EAAT) program on cardiorespiratory fitness (CRF) in children with cerebral palsy (CP). Design: An evaluator-blinded, parallel, two-arm, randomized controlled clinical trial with 1:1 randomization. Settings/Location: A tertiary university hospital and a local arena. Subjects: Forty-six children with CP (24 boys and 22 girls) classified as Gross Motor Function Classification System levels I, II, or III were included. Interventions: The EAAT program was conducted for 40 min twice a week for 16 weeks (32 lessons). Outcome measures: Clinical global impression scales, motor capacity, cardiopulmonary fitness, and habitual physical activity was measured on both groups before and after the 16-week period. Results: Changes in the Clinical Global Impression-Severity scale and Clinical Global Impression-Improvement scale scores were not different between the groups after the intervention. Analysis of covariance revealed statistically significant differences in Gross Motor Function Measure 66 (GMFM 66) (p < 0.05) and Pediatric Balance Scale (p < 0.001) in motor capacity and resting heart rate (HRrest) (p < 0.001) in CRF, between the EAAT group and the control group. Subgroup analysis using multiple linear regression analysis revealed that the GMFM 66 changes had a statistically significant effect on the HRrest changes in the EAAT group (p < 0.05). Conclusions: The present study showed decreased HRrest in children with CP after completing the 16-week EAAT program. This improvement was explained by the improvement of GMFM 66 in the EAAT group. Thus, EAAT may be among the endurance training programs that could be offered to children with CP to improve their CRF. Clinical Trial Registration number: NCT03870893.

Impact of Equine-Assisted Interventions on Heart Rate Variability in Two Participants with 22q11.2 Deletion Syndrome: A Pilot Study

People with disabilities due to genetic origin often present high levels of stress: non-pharmacological interventions such as Equine-Assisted Interventions (EAI) may be a useful strategy. The objective of this pilot study was to evaluate stress levels in two participants with 22q11.2 deletion syndrome diagnosis, immediately after carrying out the EAI. A single case experimental design methodology was chosen due to the small sample size. Two participants with 22q11.2 Deletion Syndrome, a rare disease, with different comorbidities were included. The present study considered the EAI as the independent variable while the Heart Rate Variability (HRV) represented the dependent one, as HRV is considered an indicator of stress level. Measurements were performed before and after carrying out the interventions. The results showed an HRV increase in one of the participants and an increase in the arousal level evidenced by a decrease in his HRV. After having carried out the program, EAI seems to cause an impact on the activation level of the participants depending on the typology and nature of the intervention. However, these results should be treated with caution due to the small sample size. This study is a pilot to test the feasibility of the proposed interventions on the variable under study.
