Robotic animal-assisted therapy as a complementary therapy in clinical practice: Exploring animal-assisted intervention professional perspectives.

BACKGROUND: and Purpose: Animal-Assisted Therapy (AAT) is a therapy that incorporates animals to improve the motor, social, behavioral, and/or cognitive functioning of participants. AAT has been shown to be a beneficial intervention for a wide range of populations. Although, researchers have suggested concerns in implementing AAT. The purpose of this study is to gain insight into the perspectives of therapists who incorporate AAT into their programs and to explore benefits and ethical considerations within the field of AAT. This study also aims to seek possible implications for robotic animal-assisted therapy (RAAT). MATERIALS AND METHODS: Professionals from the Association of Animal-Assisted Intervention Professionals (AAAIP) were recruited, along with members from multiple AAT private and public Facebook groups. Participants completed an anonymous online semi-structured survey, exploring their experience with and perspectives on both AAT and RAAT. Fourteen participants' responses were analyzed using Dedoose software to identify common themes in the responses. RESULTS: The results of this study provide various perspectives from professionals in different settings on the benefits of AAT, concerns about AAT, and the implication for the utilization of RAAT. The data indicated that most of the participants have not incorporated RAAT into practice. However, many of the participants believed that RAAT can be an alternative or preparatory intervention when interaction with live animals is not possible. The data collected further contributes to an emerging niche setting.

Inside out: heart rate monitoring to advance the welfare and conservation of maned wolves (Chrysocyon brachyurus).

Anthropogenic change is a major threat to individual species and biodiversity. Yet the behavioral and physiological responses of animals to these changes remain understudied. This is due to the technological challenges in assessing these effects in situ. Using captive maned wolves (Chrysocyon brachyurus, n = 6) as a model, we deployed implantable biologgers and collected physiological data on heart rate (HR) and heart rate variability (HRV) over a 1-year period. To test for links between HR and changes in the environment we analysed HR daily rhythms and responses to potential stressors (e.g. physical restraint, change in housing conditions, short-distance transportation and unfamiliar human presence). The 2-min HR averages ranged from 33 to 250 bpm, with an overall rest average of 73 bpm and a maximum of 296 bpm. On average, HRV was higher in females (227 ± 51 ms) than in males (151 ± 51 ms). As expected, HR increased at dusk and night when animals were more active and in response to stressors. Sudden decreases in HR were observed during transportation in three wolves, suggestive of fear bradycardia. We provide the first non-anesthetic HR values for the species and confirm that behaviour does not always reflect the shifts in autonomic tone in response to perceived threats. Because strong HR responses often were not revealed by observable changes in behaviour, our findings suggest that the number and variety of stressors in ex situ or in situ environments for maned wolves and most wildlife species may be underestimated. Our study also shows that integrating biologging with behavioral observations can provide vital information to guide captive management. Similar technology can be used to advance in situ research for developing more effective welfare, management and conservation plans for the species.

Comparison of two methodologies for the enrichment of mononuclear cells from thawed cord blood products: The automated Sepax system versus the manual Ficoll method.

BACKGROUND AIMS: Umbilical cord blood (CB) is being used as a source of hematopoietic stem cells (HSCs) and immune cells to treat many disorders. Because these cells are present in low numbers in CB, investigators have developed strategies to expand HSCs and other immune cells such as natural killer (NK) cells. The initial step in this process is to enrich mononuclear cells (MNCs) while depleting unwanted cells. The manual method of MNC enrichment is routinely used by many centers; however, it is an open system, time-consuming and operator dependent. For clinical manufacturing, it is important to have a closed system to avoid microbial contamination. METHODS: In this study, we optimized an automated, closed system (Sepax) for enriching MNCs from cryopreserved CB units. RESULTS: Using Sepax, we observed higher recovery of total nucleated cells (TNC), CD34+ cells, NK cells and monocytes when compared to manual enrichment, despite similar TNC and CD34+ viability with the two methods. Even though the depletion of red blood cells, granulocytes and platelets was superior using the manual method, significantly higher CFU-GM were obtained in MNCs enriched using Sepax compared to the manual method. This is likely related to the fact that the automated Sepax significantly shortened the processing time (Sepax: 74 - 175 minutes versus manual method: 180 - 290 minutes). The use of DNAse and MgCl2 during the Sepax thaw and wash procedure prevents clumping of cells and loss of viability, resulting in improved post-thaw cell recovery. DISCUSSION: We optimized enrichment of MNCs from cryopreserved CB products in a closed system using the Sepax which is a walk away and automated processing system.

Prevalence of Cognitive Impairment in Recently Diagnosed Type 2 Diabetes Patients: Are Chronic Inflammatory Diseases Responsible for Cognitive Decline?

OBJECTIVE: To estimate the prevalence of cognitive impairment (CI) among patients recently diagnosed with type 2 diabetes (RDD) and to identify any relationships between CI and RDD comorbidities. METHODS: One thousand seven hundred twelve patients with RDD participated in a cross-sectional study. The patients' sociodemographic and clinical data were registered. RESULTS: The sample population had an average age of 51 ± 11 years, and 63.26% of the patients were female. CI was diagnosed in 38 patients (2.2%) and was more common among both females (2.8% vs. 1.3%, p = 0.063) and the elderly (0% at an age ≤ 30 years vs. 10.4% at an age > 70 years, p = 0.0001). Rheumatoid arthritis (present in 15.8% vs. absent in 2.1%) and asthma (13% vs. 2.1%) correlated significantly with CI based on the results of our logistic regression analysis. CONCLUSION: Age, female gender, rheumatoid arthritis and asthma are risk factors for CI in the setting of RDD.

Dopaminergic DA1 signaling couples growth-associated protein-43 and long-term potentiation in guinea pig hippocampus.

The basic goal of the project was to determine whether dopaminergic DA1 receptor (DA1R) signaling couples growth-associated protein 43 (GAP-43; a putative "plasticity" protein) and long-term potentiation (LTP; an enduring form of synaptic plasticity). Thus, guinea pigs were prepped to stimulate the CA3 and evoke population spikes in the CA1 neurons in the hippocampus in vivo. Animals were injected with either saline or SCH23390 (a selective DA1R antagonist), 1-2 h prior to recordings. It was found that tetanic stimulation (100 Hz, 1 s, three trains at 15 s intervals) readily produced early-LTP and late-LTP in the saline group. In contrast, none of the guinea pigs pre-treated with SCH23390 developed late-LTP, though early-LTP had been present. Furthermore, both GAP-43 mRNA and protein were up-regulated after LTP induction in the saline group. However, GAP-43 protein up-regulation was blocked in animals treated with SCH23390. Anti-GAP-43 immunoreactivity was intense in CA3/CA1 synaptic regions, whereas GAP-43 mRNA hybridization was localized to somatic layers in the hippocampus. Altogether, our results suggest that dopaminergic DA1 signaling partly couples GAP-43 and LTP.
