Background:  To evaluate the effects of pet therapy on cognitive function, mood and perceived quality of life on elderly inpatients (mean age 84.7 years; 95.2% women) affected by dementia, depression and psychosis.

Animal-assisted interventions for elderly patients affected by dementia or psychiatric disorders: A review

OBJECTIVE The aim of this literature review was to assess the effects of Animal-Assisted Interventions (AAI) on elderly patients with dementia or various psychiatric disorders. METHODS We conducted a comprehensive literature search using the online PubMed network of the US National Library of Medicine & National Institutes of Health, Embase, PsycINFO, with the purpose of investigating AAI effects on cognitive functions, mood, and behaviour. RESULTS A total of 18 articles on dementia and 5 on psychiatric disorders were included in the present review. AAI were found to have positive influences on demented patients by reducing degree of agitation and by improving degree and quality of social interaction. Few studies have assessed the effects of AAI on mood, and even fewer have assessed its consequences on cognitive functions. The results that are available indicate a positive effect on communication and coping ability, but none on cognitive performance. A substitute pet robot yielded encouraging results, but its use requires further investigation. The few studies conducted for elderly patients presenting a variety of psychiatric diagnoses produced controversial findings. CONCLUSIONS In spite of the encouraging results of AAI, much more research examining the issue of optimal AAI duration, frequency of sessions, and suitable target group is needed.

Vision and hearing impairments are associated with depressive--anxiety syndrome in Italian elderly.

Objective: The aim of this study was to evaluate the association between vision and hearing impairment and depressive–anxiety syndrome in a large population participating in the Faenza Project, Northern Italy. Method: The study population consisted of 7389 participants not affected by dementia, 4408 (59.7%), of whom were women, mean age ± standard deviation (±SD) 71.9 (±7.7) years. Information about previous or current psychiatric symptoms, including sleeping and eating habits, non-verbal language and ability in activity of daily living was used to investigate depressive and anxiety syndrome. A semi-structured interview was administered to survey the presence of sensory impairment. Logistic regression analyses were used to evaluate the association between sensory impairment and depressive–anxiety syndrome estimating Odds ratio (OR) and 95% confidence interval (95% CI). Results: The prevalence of vision and hearing impairment was 1.4% and 0.2%, respectively, with an increasing trend in people aged 75+ years (p < 0.001). The prevalence of depressive syndrome was higher among vision-impaired participants (20.2% vs. 9.3%, p < 0.001), especially women (22.9%) and persons aged 75+ years (22.1%). The prevalence of anxiety syndrome was higher in the hearing-impaired group (25.0% vs. 11.0%, p = 0.09). Vision-impaired participants, especially women and participants aged 75+ years had have a twofold higher probability to have depressive syndrome (OR = 2.03, 95% CI = 1.21–3.38), and hearing-impaired individuals showed an increased probability of presenting anxiety syndrome (OR = 2.71, 95% CI = 0.86–8.55), although these results were not statistically significant. Conclusion: This studys findings suggest that sensory impairment in older adults can increase their probability of experiencing depressive and anxiety syndrome. Correction of these deficits could improve the quality of life in this population.

Prevalence and characteristics of mild cognitive impairment in the general population. Data from an Italian population-based study: The Faenza Project.

The aim of this cross-sectional study is to investigate mild cognitive impairment (MCI) using the Mini-Mental State Examination in an Italian cohort (N = 6921; mean age 71.6 ± 7.5; 59.2% women). First, we applied psychometrically derived criteria for MCI regardless of presence/absence of subjective cognitive complaints (SCC); second, we implemented the analyses only on the SCC subsample. The estimated MCI prevalence was 6.0%. Amnestic- and non-amnestic MCI single domains accounted for 4.3% and 13.5% of the cases, respectively. Amnestic- and non-amnestic MCI multiple domains occurred in 2.0% and 4.5% of the cases, respectively. The 33.8% of the SCC subsample (6.0% of the cohort) had MCI. Stroke, diabetes and depressive symptoms were commonly associated to MCI suggesting that this common condition is associated with many correlates in Italian older persons. It deserves attention since it is early detectable and potentially preventable.

Anxiety Symptoms in 74+ Community-Dwelling Elderly: Associations with Physical Morbidity, Depression and Alcohol Consumption

Objective Anxiety among community-dwelling older adults has not been studied sufficiently. The aims of this cross-sectional population-based study were to estimate the point prevalence of clinically relevant anxiety symptoms and to describe their socio-demographic and clinical features, with particular focus on the association with somatic illnesses. Methods Three-hundred-sixty-six non-demented older adults (mean age 83.7±6.2, range 74–99 years) from the Faenza Project (Northern Italy) were assessed using the Cambridge Mental Disorders of the Elderly Examination-Revised (CAMDEX-R) and the Geriatric Anxiety Inventory short form (GAI-sf). Multi-adjusted regression analyses were used to estimate Odds Ratio (OR) and 95% Confidence Intervals (95% CI). Results Clinically relevant anxiety symptoms occurred in one out of five participants (point prevalence 21.0%) and were significantly associated with depression (OR 5.6 per rank; 95% CI: 3.1–10.1), physical morbidity (OR 3.5 per illness; 95% CI: 1.0–11.9) and female gender (OR 2.8; 95% CI: 1.4–5.5). Further, there were significant associations with a consumption of alcohol exceeding 1 alcoholic unit/day. Conclusions Anxiety symptoms are very common in older subjects, especially when medically ill. Depression and alcohol consumption often co-occur with late-life anxiety symptoms, thus requiring special attention in daily clinical practice.

Association of SORL1 Alleles with Late-Onset Alzheimer's Disease. Findings from the GIGAS_LOAD Study and Mega-Analysis

The pathophysiology of Alzheimers disease (AD) is influenced by sorting-protein related receptor (sorLa) that is less expressed in AD patients. The gene encoding sorLa (SORL1) has been investigated as a susceptibility factor for late-onset AD (LOAD) with conflicting results. Our objectives were to confirm the association between SORL1 SNPs and LOAD in two independent South-European centers and to perform a mega-analysis of published samples. We analyzed three SORL1 SNPs (intron 6: rs668387; rs689021; rs641120) from the Greece-Italy Genetic Association Study on lateonset AD (GIGAS_LOAD). Greek sample included 96 patients with LOAD (DSM-IV) and 120 unrelated controls. In Italy, a community-based sample is ongoing. 47 LOAD patients and 165 controls were recruited until study endpoint. These samples and previously published ones (Alzgene) were pooled as in a single study. A test for trend was used to analyze genotype association. In the GIGAS_LOAD sample no association was detected between SORL1 genotypes and LOAD. Conversely all SNPs were associated with LOAD in mega-analysis based on ordinal classification of genotypes (Armitages test: p < 0.001). Although our analysis of pooled samples has positive results for the association between SORL1 and AD, there is substantial heterogeneity across studies. Thus further examination into SORL1 SNPs and the population is necessary to determine the role of SORL1 in LOAD.

P02-163 The use of MMSE to identify mild cognitive impairment (MCI). A population-based study

Aims To evaluate the prevalence of MCI and its subtypes in the Faenza Project, using the Mini-Mental State Examination (MMSE). Methods Subjects living in the municipality of Faenza were clinically assessed. The diagnosis of MCI was achieved according to international criteria using a double-step procedure: first, we excluded subjects with dementia, functional impairment and MMSE Results 2,720 (40.3%) participants met MCI criteria. Prevalence were 4% (amnestic MCI), 26.5% (single non-memory MCI), 4.4% (multidomains amnestic MCI), and 5.4% (multidomains non-amnestic MCI). Conclusions MCI is common among Italian elderly. In our study prevalence are higher than reported in other population-based studies. The use of MMSE with different operational criteria, diverse sampling and assessment procedure might explain such discrepancy. The role of MMSE to identify persons with mild cognitive deficits deserves concerns. However, MMSE is largely used in both clinical practice and research and has been suggested as a useful screening tool for assessing the degree of cognitive impairment in the guidelines for the Report of the Quality Standards Subcommittee of the American Academy of Neurology.

P01-364 - A Pet therapy intervention on elderly inpatients: an epidemiological study

Objectives The aim of the present study is to evaluate the effects of Pet Therapy intervention on cognitive function, mood and perceived quality of life on elderly subjects (mean age 84.7 years; 95.2% women) living in a nursing home. Methods Participants were 21 subjects affected by mental illness including dementia, depression and psychosis (diagnosis based on the International Statistical Classification of Disease - ICD-10). The Mini-Mental State Examination (MMSE) and the 15-items Geriatric Depression Scale (GDS) were administered to ten persons (pet-group) and eleven subjects (control-group) together with a self-perceived quality of life questionnaire. The pet-group underwent a dog-assisted educational intervention lasting 90 minutes, once a week for six weeks. MMSE and GDS mean scores were compared between and within groups by Students t-test. Results The mean age ± standard deviation of the overall sample was 84.7±9.9 years. Mean schooling level was 4.0±3.4 years. Dementia was the most frequent diagnosis (47.6%), followed by psychosis (33.3%) and depression (19.0%). Both pet-group and control-group improved on GDS and MMSE. Within the pet-group, GDS symptoms decreased by 50% (from 5.9 to 2.7, p=0.013), whereas mean MMSE score increased by 4.5 (p=0.060). The between group comparison showed positive effect of Pet intervention on GDS (p=0.070). Furthermore, most of the participants reported an improvement of their perceived quality of life. Conclusions According to the most recent literature, our findings suggest that Pet Therapy program can be efficient in improving depressive symptoms and cognitive function in residents of long-term care facilities with mental illness.

P-545 - Predictors of drop-out in patients with eating disorders (ED)

Introduction Drop-out is a serious problem in ED which remains poorly understood. Aims To describe socio-demographic and clinical factors associated with drop-out in order to prevent this phenomenon with individualized strategies. Methods A semi-structured clinical interview was administered to 92 adult out-patients attending a third level centre for ED. Measures of psychopathology (EDE12th, BDI, STAI, MINI, SCID-II) were collected to achieve diagnoses. The study population included completers (CO) and drop-outs (DO) which consist of patients that did not complete the baseline assessment Failing in Alliance (FA) and persons who Failed in Treatment (FT). Results The drop-out rate is 34,8%, including 17,4% of FA and 17,4% of FT. DO were less likely to have Anorexia Nervosa at Onset and Obsessive-Compulsive Personality Disorder, while serious Depressive Symptoms, Borderline Personality Disorder and Bulimia Nervosa predicted premature attrition. After multivariate analysis only the last three remain statistically significantly. Considering the period of drop out, we found that Bulimia Nervosa and Borderline Personality Disorder were independent correlated with FA respectively (OR=5,800; 95%CI 1,574–21,368) and (OR=5,782; 95%CI 1,135–29,449). Conversely FT had a higher probability to have serious Depressive Symptoms (OR= 12,289; 95%CI 1,187–127,207). Conclusions Drop-outs in ED include two different subpopulations: failure in alliance (FA) and failure in treatment (FT) characterized by different clinical characteristics. Bulimia Nervosa and Borderline Personality Disorder were predictors of FA, whereas serious Depressive Symptoms were predictors of FT.

P01-508 - Leading cause of re-hospitalization in an Italian acute psychiatric unit: preliminary results

Objectives To describe the leading cause of re-hospitalization in an Acute Psychiatric Unit of a general hospital in Bologna, Northern Italy. Methods All repeated admissions (>3consecutive admissions in 18 months) were recorded thanks to the Hospital Informatic System. Case-history were reviewed to collect information, diagnoses were based on the ICD-10. Results In the indexed period, 392 admissions were registered for 152 patients (mean age 44; 46,1% women). At least one precipitating cause was present in 64% of admissions. The most frequent were psycho-social stress such as family conflicts, parental separations, relational problems, job or economic difficulties (39%). The co-occurrence of 2+ of such factors was common (20%). Tricky situation within the psychiatric rehabilitation service (20%), low compliance to treatments (7%), alcohol/drugs abuse (7%), and low insight (3%) were the remaining associated factors. All the re-admissions of patients with poor insight or reduced compliance were due to the same cause. Poor adherence to therapies was more frequent in bipolar disorder compared with other diagnosis (17%vs7%, p Conclusions Regardless of diagnoses, in almost a half of the admissions a single psycho-social stress is sufficient to lead to re-hospitalization; in personality disorders the contemporary presence of 2+ stressors is needed to overcome the capacity compensation of the patient. Low insight is frequently associated to re-admissions. Tailored treatments might reduce the frequency of re-hospitalization.
