RESUMO
Although diagnosis of osteoarthritis (OA) has been recently linked to euthanasia in dogs, no prior work has examined the roles of caregiver burden or treatment satisfaction in this relationship. We expected that there would be an indirect effect of caregiver burden on the association between consideration of euthanasia and clinical signs of OA, but that this effect would be influenced by owner satisfaction. Cross-sectional online evaluations were completed by 277 owners of dogs with OA recruited through social media. Canine OA-related pain and functional impairment, owner consideration of euthanasia, caregiver burden, and satisfaction were examined. Relationships among OA-related pain and functional impairment, owner consideration of euthanasia, caregiver burden, and satisfaction were statistically significant (P 0.01 for all). Cross-sectional mediation analysis demonstrated a statistically significant indirect effect of caregiver burden on the relationship between consideration of euthanasia and OA-related clinical signs (bias-corrected 95% confidence interval [BC 95% CI], 0.001-0.009), which was significantly moderated by owner satisfaction (BC 95% CI, -0.003 to -0.0002). Findings align with prior work connecting canine OA to euthanasia. The current study extends past research to demonstrate that caregiver burden in the owner may be partially responsible for this relationship. The moderating role of owner satisfaction suggests that optimizing owner impressions of treatment and the veterinary team could attenuate these relationships, potentially decreasing the likelihood of premature euthanasia for dogs with OA.

AIMS: To determine whether an educational programme targeting the reaction of veterinary personnel to difficult client interactions reduced burden transfer, stress and burnout in veterinary staff. METHODS: Employees of three small-animal veterinary hospitals in the south-western United States of America were recruited and randomised to intervention (educational programme; n = 16) or control (no intervention; n = 18) groups. Participants of this randomised, parallel arms trial completed pre-programme assessment including the Burden Transfer Inventory (BTI), Perceived Stress Scale, and Copenhagen Burnout Inventory. Assessment was followed by two, group-format educational sessions, based on acceptance and commitment training, tailored to reducing reactivity to difficult veterinary client interactions (intervention group only). After training was completed, both groups were assessed using the same measures and the intervention participants provided use and acceptability ratings. RESULTS: Intervention participants rated the programme as useful and appropriate, and reported that programme techniques were used a median of 43 (min 9, max 68) times during the 2 weeks prior to retesting. Relative to pre-programme scores, median post-programme scores for reaction (subscore of BTI) to difficult client interactions decreased in the intervention group (33 vs. 54; p = 0.047), but not in the control group (51 vs. 59; p = 0.210). Changes in median scores for stress and burnout from pre- to post-programme were non-significant for both groups. CONCLUSIONS: This pilot and feasibility trial showed high rates of acceptability and use by participants, as well as promising reductions in burden transfer. A larger scale clinical trial with follow-up at extended time points is needed to more fully examine the efficacy of this novel programme. CLINICAL RELEVANCE: Preliminary findings suggest this programme may be a useful approach to reducing occupational distress for individuals working in veterinary practice.

Caregiver burden, found in many clients with a chronically or terminally ill companion animal, has been linked to poorer psychosocial function in the client and greater utilization of non-billable veterinary services. To reduce client caregiver burden, its determinants must first be identified. This study examined if companion animal clinical signs and problem behaviors predict veterinary client burden within broader client- and patient-based risk factor models. Data were collected in two phases. Phase 1 included 238 companion animal owners, including those with a sick companion animal (n=119) and matched healthy controls (n=119) recruited online. Phase 2 was comprised of 602 small animal general veterinary hospital clients (n=95 with a sick dog or cat). Participants completed cross-sectional online assessments of caregiver burden, psychosocial resources (social support, active coping, self-mastery), and an item pool of companion animal clinical signs and problem behaviors. Several signs/behaviors correlated with burden, most prominently: weakness, appearing sad/depressed or anxious, appearing to have pain/discomfort, change in personality, frequent urination, and excessive sleeping/lethargy. Within patient-based risk factors, caregiver burden was predicted by frequency of the companion animal's signs/behaviors (P<.01). Within client-based factors, potentially modifiable factors of client reaction to the animal's signs/behaviors (P=.01), and client sense of control (P<.04) predicted burden. Understanding burden may enhance veterinarian-client communication, and is important due to potential downstream effects of client burden, such as higher workload for the veterinarian. Supporting the client's sense of control may help alleviate burden when amelioration of the companion animal's presentation is not feasible.

OBJECTIVE: Deficits in traditional cognitive domains (e.g. executive function and memory) are common in persons with severe obesity, but it is unclear if this pattern of dysfunction extends to social cognition. The present study examined whether cognitive impairment was associated with poorer emotion recognition in bariatric surgery candidates. METHODS: One hundred sixteen bariatric surgery candidates (mean age = 43.62 ± 11.03; 81% female) completed the computerized Integneuro test battery as part of a larger study visit. In addition to assessing traditional cognitive domains, the Integneuro also includes an emotion recognition measure. This task presents 48 faces (eight different individuals depicting neutral, happiness, fear, sadness, anger and disgust), and participants must choose the correct verbal label from six expression options. Number of correct responses and average reaction time for correct responses served as primary dependent variables. RESULTS: Stepwise multiple regression analyses revealed that older age, more maze errors, and history of hypertension predicted less accuracy in emotion recognition (adjusted R2 = .22, F[3, 111] = 11.86, p < .001) and that slower switching of attention-digits, worse long-delay recall, and older age predicted speed of responses (adjusted R2 = .26, F[3, 111] = 13.00, p < .001). DISCUSSION: Results show that cognitive dysfunction is associated with poorer performance on a computerized test of emotion recognition, consistent with those in persons with a range of psychiatric and neurological disorders. Additional work is needed to clarify the mechanisms and functional impact of these impairments, especially in relation to weight loss following bariatric surgery.
RESUMO
INTRODUCTION: Diabetes is associated with cognitive impairments, particularly in executive functioning and memory. AIM: The aim was to describe cognitive functioning in Type 1 (T1DM) and Type 2 (T2DM) diabetes compared to healthy controls in a Serbian sample. METHOD: We studied 15 patients with adult onset T1DM (age range 19-60 years), 37 patients with T2DM (age range 50-77 years), and 32 healthy controls (28-78 years). All participants underwent comprehensive neuropsychological assessment. RESULTS: T2DM subjects exhibited poorer performance than healthy controls in global cognitive performance, as well as verbal learning and memory. After correcting for multiple comparisons, follow-up examination of individual tests showed significantly poorer performance only on Trail Making Test Part B (TMT-B). Effect sizes for T2DM versus healthy controls ranged from medium to large for several cognitive variables, while comparisons between T1DM and the other two groups tended to yield much smaller effects. CONCLUSION: T2DM is associated with poorer cognition, particularly in executive functions, learning/memory, and global cognition. Lack of group differences may be due to use of an adult onset T1DM sample, relatively young age of our T2DM sample, or characteristics of healthy control subjects in our Serbian sample.

Convergent evidence demonstrates that greater physical activity is associated with better cognitive functioning across many patient and healthy samples. However, this relationship has not been well examined among obese individuals and remains unclear. The present study examined the relationship between performance-based measures of attention/executive function and self-reported physical activity, as measured by the International Physical Activity Questionnaire, among lean (n = 36) and obese (n = 36) college students. Lean individuals performed better than obese individuals on measures of attention/executive function. No significant differences in self-reported physical activity emerged between weight groups. Higher self-reported physical activity was related to faster reaction time in lean individuals but slower reaction time in obese individuals. Additionally, in lean individuals, higher levels of self-reported physical activity were related to more errors on a task of speeded inhibitory control. The results are consistent with previous research demonstrating that greater physical activity is associated with faster attention and executive function abilities in healthy samples and highlight the importance of examining reaction time and accuracy indices separately on these measures. The lack of association among obese individuals may be due in part to inaccurate self-report in the current study. Additionally, the cognitive consequences of obesity may outweigh the benefits of physical activity in this group. Future work should investigate these associations in obese individuals using physical activity interventions, as well as a combination of self-report and objective measures to investigate discrepancies in reporting.

Accumulating evidence indicates obesity is associated with reduced cognitive functioning, particularly attention and executive function, as well as maladaptive eating behaviour such as uncontrolled eating. The current study examined relationships between eating patterns and attention/executive function test performance in lean and obese individuals. Sixty-two (32 lean, 30 obese) healthy young adults (21.13 ± 2.31 years; 56.5% female) completed the abbreviated Three-Factor Eating Questionnaire (TFEQ-R18) to assess eating patterns, including uncontrolled eating, cognitive restraint, and emotional eating. The Go/No-Go (GNG), Running Memory Continuous Performance Test (RCMPT) and Standard Continuous Performance Test from the Automated Neuropsychological Assessment Metrics-4 were administered as measures of executive functioning and attention. An independent samples t-test revealed greater report of uncontrolled eating in obese compared with lean participants (t[60] = -2.174, P < 0.05; d = -0.55) but no differences in cognitive restraint or emotional eating. Multivariate analysis of variance revealed cognitive differences between lean and obese groups (F[6, 54] = 3.86, P < 0.005; λ = 0.70; ηp(2) = 0.30), which were driven by GNG reaction time (F[1, 59] = 8.36, P < 0.01, d = 0.74). Pearson bivariate correlations revealed a positive correlation between uncontrolled eating and reaction time on GNG (r = 0.343, P < 0.05) and RMCPT (r = 0.267, P < 0.05) in all participants. Relative to lean participants, obese individuals reported higher levels of uncontrolled eating and exhibited slower performance on a task of inhibitory control. In the full sample, greater self-reported dyscontrol in eating behaviour was related to slower inhibitory control and working memory. Results support a link between executive function and control of eating behaviour. Obese individuals may be more vulnerable to difficulties in these domains relative to those who are lean.

OBJECTIVE: Loss of appetite and body mass are common in older adults and are associated with negative consequences. Research indicates that these processes likely involve increases in serum brain-derived neurotrophic factor (BDNF). Animal and human models demonstrate that BDNF may serve a regulatory function in food intake, but no study has addressed the possibility that BDNF may be involved in appetite reduction and loss of body mass in older adults. DESIGN AND PARTICIPANTS: 34 older adults without significant neurological or psychiatric history underwent fasting blood draw and measurement of body composition. Appetite and eating behavior were assessed by questionnaire and related to serum BDNF levels. RESULTS: Partial correlations showed serum BDNF levels were inversely related to appetite (r = -.38, p = .02). No significant correlations emerged between serum BDNF and age, diet, or body composition. CONCLUSIONS: The current study extends past work and shows that BDNF is associated with appetite in healthy older adults. Further work is needed to clarify mechanisms for these findings, particularly prospective studies.

Heterogeneity in cognitive performance in schizophrenia and schizotypy may be accounted for, by differences in predominant symptom presentation. However, studies have not demonstrated consistent relations between specific cognitive impairments and specific trait dimensions in either population. Studies of group differences, particularly those using groups defined by cluster analyses are rare, but suggest that the negative trait dimension is more associated with executive function deficits, positive trait dimension with memory and attentional difficulties, and the disorganized trait dimension with attention problems. The present study examined the relation of schizotypal trait dimensions and executive function deficits in schizotypal individuals using two methods. Correlations between schizotypal factor scores and cognitive measures demonstrated that high negative symptoms were associated with poor performance on the WCST, while high scores on other trait dimensions were related to a better WCST performance. High scores in all trait dimensions were related to the naïve rater's observations of unusual social behavior. A cluster analysis revealed three groups of schizotypals (predominantly negative presentation, predominantly positive symptom presentation, and high on all dimensions). The cluster with predominantly negative symptoms performed worse, than all other schizotypal groups and unselected controls, on the WCST and a higher percentage of them were rated as clinically impaired on the neuropsychological battery. However, schizotypals who were high on all trait dimensions were rated as having the most unusual social behavior by the naïve raters. Overall, results support the hypothesis of a relation between executive function deficits and negative symptoms in schizotypal individuals.

Factor analytic studies have long supported the division of schizophrenic symptoms into three relatively orthogonal factors: positive symptoms, negative symptoms, and disorders of relatedness/disorganization. Similarly, factor analyses of schizotypy often yield three factors: positive symptoms, negative symptoms, and social anxiety or disorganization. Recent cluster analyses, however, suggest that not all patients can be simply categorized according to these factors. Cluster analyses of schizotypal symptoms tend to result in clusters of individuals who are low in all factors, high in more than one factor, or high predominantly in one factor. The present study sought to compare factor and cluster models of schizotypal symptoms, as measured by the SPQ, PAS, and MIS, in unselected individuals and highly schizotypal individuals. Consistent with prior research, factor analysis of a large unselected undergraduate sample yielded three factors: "positive", "negative", and "disorganized." Factor analysis of schizotypal undergraduates produced the same three factors, plus a fourth designated "paranoid thinking." In contrast, cluster analysis of the unselected sample yielded four clusters ("low schizotypy", "average schizotypy", and "high schizotypy", plus "positive/disorganized"). Cluster analysis of the schizotypal subsample produced four clusters: "low schizotypy", "positive", "negative" and "high schizotypy."
