RESUMEN
BACKGROUND: Down syndrome (DS) is characterised by premature ageing that affects selected organ systems, and persons with this condition can present patterns of co-morbidities and deficits often observed in the older population without DS. However, information on the characteristics of adult persons with DS is limited. The objective of the study is to describe characteristics of adults with DS collected with a standardised, comprehensive assessment instrument. METHODS: Cross-sectional study. Four hundred thirty adults with DS (age range 18/75 years) from three countries (Italy, n = 95; USA, n = 175; and Canada, n = 160). A standardised assessment instrument (interRAI intellectual disability) was used to assess sample characteristics. RESULTS: Mean age ranged from 35.2 (standard deviation 12.0) years in the US sample to 48.8 (standard deviation 9.0) years in the Canadian sample. Most participants in the Italian and US sample were living in private homes, while more than half of those in the Canadian sample were institutionalised. Prevalences of geriatric conditions, including cognitive deficits, disability in the common activities of daily living, symptoms of withdrawal or anhedonia, aggressive behaviour, communication problems, falls and hearing problems were high in the study sample. Gastrointestinal symptoms, skin and dental problems and obesity were also frequently observed. CONCLUSIONS: Adults with DS present with a high level of complexity, which may suggest the need for an approach based on a comprehensive assessment and management that can provide adequate care. Further research is needed to understand better the effectiveness of such an approach in the DS population.

This review discusses the interplay between multimorbidity (i.e. co-occurrence of more than one chronic health condition in an individual) and functional impairment (i.e. limitations in mobility, strength or cognition that may eventually hamper a person's ability to perform everyday tasks). On the one hand, diseases belonging to common patterns of multimorbidity may interact, curtailing compensatory mechanisms and resulting in physical and cognitive decline. On the other hand, physical and cognitive impairment impact the severity and burden of multimorbidity, contributing to the establishment of a vicious circle. The circle may be further exacerbated by people's reduced ability to cope with treatment and care burden and physicians' fragmented view of health problems, which cause suboptimal use of health services and reduced quality of life and survival. Thus, the synergistic effects of medical diagnoses and functional status in adults, particularly older adults, emerge as central to assessing their health and care needs. Furthermore, common pathways seem to underlie multimorbidity, functional impairment and their interplay. For example, older age, obesity, involuntary weight loss and sedentarism can accelerate damage accumulation in organs and physiological systems by fostering inflammatory status. Inappropriate use or overuse of specific medications and drug-drug and drug-disease interactions also contribute to the bidirectional association between multimorbidity and functional impairment. Additionally, psychosocial factors such as low socioeconomic status and the direct or indirect effects of negative life events, weak social networks and an external locus of control may underlie the complex interactions between multimorbidity, functional decline and negative outcomes. Identifying modifiable risk factors and pathways common to multimorbidity and functional impairment could aid in the design of interventions to delay, prevent or alleviate age-related health deterioration; this review provides an overview of knowledge gaps and future directions.

BACKGROUND: There is increasing evidence that frailty may play a role in chronic diseases, but the associations with specific chronic disorders are still unclear. OBJECTIVES: To conduct a systematic review and meta-analysis assessing the association of anaemia and frailty in observational studies. METHODS: The review was performed according to PRISMA guidelines. We searched PubMed, Web of Science, and Embase from 01/01/2002-10/09/2017. Pooled estimates were obtained through random effect models and Mantel-Haenszel weighting. Homogeneity was assessed with the I2 statistic. Publication bias was assessed with Egger's and Begg's tests. RESULTS: Nineteen studies were included; two longitudinal, seventeen cross-sectional. All studies except three reported an association between anaemia and frailty. The pooled prevalence of prefrailty in individuals with anaemia was 49% (95% CI=38-59%; I2=89.96%) and 24% (95% CI=17-31%; I2= 94.78%) for frailty. Persons with anaemia had more than a twofold odds of frailty (pooled OR=2.24 95% CI=1.53-3.30; I2=91.8%). Only two studies longitudinally examined the association between anaemia and frailty, producing conflicting results. CONCLUSIONS: Frailty and prefrailty are common in anaemic persons. Older persons with anaemia have more than a two-fold increased odds of frailty. These results may have clinical implications, as they identify the need to assess frailty in anaemic people and investigate any potential negative effects associated with the co-occurrence of both conditions. Longitudinal research that examines temporal changes in anaemia and effect of treatment are needed to further clarify the relationship between anaemia and frailty.

Experimental evidence suggests that motor imagery (MI) engages the same neural substrates supporting actual motor activities and is likely impaired when such substrates are damaged, as in Parkinson's disease (PD). MI intuitively relies on visual imagery (VI), because mental simulations of physical movements depend on the visual retrieval of these movements. Although VI is generally considered a right hemispheric function, the hemispheric dominance of MI is still in dispute. Disparities in sidedness of motor disturbances are a distinctive feature of PD, and recent findings indicate that such disparities may similarly characterize cognition. Specifically, the deficits observed may depend upon which hemisphere is principally involved. Essentially, MI and VI are cognitive tasks subject to differential impairment and reflecting the prevalence of hemispheric impairment in PD. Motor imagery (assessed by the Vividness of Motor Imagery Questionnaire [VMIQ]) and VI (assessed by the Vividness of Visual Imagery Questionnaire [VVIQ] and Test of Visual Imagery Control [TVIC]) were examined in patients with asymmetric PD and in healthy elderly control subjects (HC group). VMIQ scores were similar in PD laterality subsets and the HC group, but VVIQ scores were significantly lower in both PD groups compared with the HC group. TVIC scores were significantly lower in the presence of left motor (right hemispheric) impairment and were predictive of left motor (right hemispheric) impairment. We suspect that MI is strongly reliant on VI and that language may mediate these two functions, to the extent that both are evoked through verbal stimuli. Working memory, both visual and verbal, is also involved in MI and VI tasks. Without due attention to laterality of symptoms, any training incorporating MI and VI may not deliver expected outcomes in the setting of asymmetric PD symptomatology.

BACKGROUND: Multimorbidity is among the most disabling geriatric conditions. In this study, we explored whether a rapid development of multimorbidity potentiates its impact on the functional independence of older adults, and whether different sociodemographic factors play a role beyond the rate of chronic disease accumulation. METHODS: A random sample of persons aged ≥60 years (n = 2387) from the Swedish National study on Aging and Care in Kungsholmen (SNAC-K) was followed over 6 years. The speed of multimorbidity development was estimated as the rate of chronic disease accumulation (linear mixed models) and further dichotomized into the upper versus the three lower rate quartiles. Binomial negative mixed models were used to analyse the association between speed of multimorbidity development and disability (impaired basic and instrumental activities of daily living), expressed as the incidence rate ratio (IRR). The effect of sociodemographic factors, including sex, education, occupation and social network, was investigated. RESULTS: The risk of new activity impairment was higher among participants who developed multimorbidity faster (IRR 2.4, 95% CI 1.9-3.1) compared with those who accumulated diseases more slowly overtime, even after considering the baseline number of chronic conditions. Only female sex (IRR for women vs. men 1.6, 95% CI 1.2-2.0) and social network (IRR for poor vs. rich social network 1.7, 95% CI 1.3-2.2) showed an effect on disability beyond the rate of chronic disease accumulation. CONCLUSIONS: Rapidly developing multimorbidity is a negative prognostic factor for disability. However, sociodemographic factors such as sex and social network may determine older adults' reserves of functional ability, helping them to live independently despite the rapid accumulation of chronic conditions.

ABSTRACTThe aim of the present study is to investigate the impact of benzodiazepine use on cognitive performance in primary care patients with first cognitive complaints. The association between the exposition to benzodiazepines (short and long half-life) and cognitive performance, evaluated through the Mini Mental State Examination (MMSE), was tested through analysis of the covariance and logistic regression models. Within the 4,249 participants (mean age 77.0 ± 8.2, 66.4% women), 732 (17%) were on benzodiazepines. When compared with non-users, short- and long-acting benzodiazepine users presented overlapping adjusted MMSE mean scores (respectively, mean MMSE score: 25.3, 95%CI 25.2-25.5; 25.4, 95%CI 25.1-25.7, and 25.9, 95%CI 25.3-26.4; p = 0.156). When tested according to the logistical regression model, after adjusting for potential confounders, no association was found between short and long acting benzodiazepine use and a MMSE < 24 (respectively, OR 0.9, 95%CI 0.7-1.2; OR 0.8, 95%CI 0.7-1.3) as compared with non-users. In conclusion, according to the results of our study, benzodiazepine use seems not to impact on cognitive performance- as assessed with the MMSE- of primary care patients referring to GPs for first cognitive complaints.

This study analyzed data of bone mineral density (BMD) from a large cohort of adults with Down syndrome (DS). BMD was found to decrease with age more rapidly in these subjects than in the general population, exposing adults with DS to an increased risk of osteoporosis and bone fracture. INTRODUCTION: Down syndrome (DS) in adulthood presents with a high prevalence of osteoporosis. However, in DS, bone mineral density (BMD) can be underestimated due to short stature. Furthermore, the rate of age-related decline in BMD and its association with gender in DS has been rarely evaluated or compared with the general population. The present study is aimed at assessing the variation of BMD with age and gender in a sample of adults with DS and to compare these data with those of the general population, after adjusting for anthropometric differences. METHODS: Adults with DS, aged 18 or older, were assessed dual-energy-X-ray-absorptiometry (DXA) at the femoral neck and at the lumbar spine. They were compared with the general population enrolled in the National Health and Nutrition Examination Survey (NHANES) 2009-2010 dataset. Bone mineral apparent density (BMAD) was calculated for each individual. RESULTS: DXA was evaluated in 234 subjects with DS (mean age 36.93 ± 11.83 years, ranging from 20 to 69 years; 50.4% females). In the lumbar spine both mean BMD (DS 0.880 ± 0.141 vs. NHANES 1.062 ± 0.167, p < 0.001) and BMAD (DS 0.138 ± 0.020 vs. NHANES 0.152 ± 0.020, p < 0.001) were significantly lower in the DS sample than in the NAHNES cohort. The same trend was observed at the femoral neck in both BMD (DS 0.658 ± 0.128 vs. NHANES 0.835 ± 0.137, p < 0.001) and BMAD (DS 0.151 ± 0.030 vs. NHANES 0.159 ± 0.028, p<0.001). Age was associated with lower femoral neck BMAD in both samples; importantly, this association was significantly stronger in the DS sample. In the lumbar spine region, no significant association between BMAD and age could be observed in both samples. CONCLUSIONS: Adults with DS have lower bone mineral density compared to the general population and they experience a steeper decline with age. Early screening programs are needed in DS population.

BACKGROUND AND PURPOSE: Drugs with anticholinergic properties might have a negative impact on cognition, but findings are still conflicting. The association was evaluated between anticholinergic drugs and cognitive performance in primary care patients with first cognitive complaints. METHODS: From April 2013 to March 2014, 353 general practitioners administered the Mini-Mental State Examination (MMSE) to patients presenting with first cognitive complaints. Drug history was collected and the anticholinergic cognitive burden (ACB) was scored and categorized as ACB 0, ACB 1 and ACB 2+. A mixed effect linear regression model was used to assess the association between ACB and MMSE score. RESULTS: Of 4249 subjects entering the study (mean age 77 ± 8.2 years, 66.4% women and mean years of schooling 8.9 ± 4.5), 25.8% received at least one drug with anticholinergic action. According to multivariate analysis, and after adjustment for several confounders, subjects with ACB 2+ had a statistically significant lower MMSE score compared with those with ACB 0 (ß -0.63; 95% confidence interval -1.19; -0.07). Subjects with ACB 1 had a non-statistically significant lower MMSE score than those with ACB 0 (ß -0.11; 95% confidence interval -0.37; 0.15). CONCLUSIONS: Anticholinergic medication might affect cognitive function in people with first cognitive complaints. Alternatives should be taken into account when possible, balancing the benefits and harms of these medications.

BACKGROUND: Proton-pump inhibitors (PPI) are extensively prescribed in older patients. However, little information is available on factors associated to PPI prescribing patterns among older patients discharged from hospital. OBJECTIVE: To evaluate the appropriateness and clinical correlates of PPI prescription at discharge in a population of 1081 older patients discharged from acute care Italian hospitals. DESIGN: We used data from the CRiteria to Assess Appropriate Medication Use among Elderly Complex Patients (CRIME) study, a multicenter observational study. The appropriateness of PPI prescriptions was defined according to the Italian Medicines Agency (AIFA) rules. Correlates of overprescribing (i.e prescribing without recognized AIFA indications) and underprescribing (i.e. not prescribing despite the presence of recognized AIFA indications) were investigated by logistic regression analysis. RESULTS: Overprescribing was observed in 30% of patients receiving PPIs at discharge. Underprescribing was observed in 11% of patients not receiving PPIs at discharge. Overprescribing of PPIs at discharge was negatively associated with age (OR=0.88, 95%CI=0.85-0.91), depression (OR=0.58, 95%CI=0.35-0.96), use of aspirin (OR=0.03, 95%CI=0.02-0.06) and systemic corticosteroids (OR=0.02, 95%CI=0.01-0.04). The negative association with number of medications (OR=0.95, 95%CI=0.88-1.03) and overall comorbidities (OR=0.92, 95%CI=0.83-1.02) was nearly significant. Conversely, older age (OR=1.09, 95%CI=1.04-1.14), use of aspirin (OR=24.0, 95%CI=11.5-49.8) and systemic corticosteroids (OR=19.3, 95%CI=11.5-49.8) and overall comorbidities (OR=1.22, 95%CI=1.04-1.42) were independent correlates of underprescribing. CONCLUSION: Overprescribing of PPIs is more frequent in younger patients with lower burden of depression, whilst underprescribing is characterized by older age and greater burden of comorbidity and polypharmacy. Hospitalization should be considered as a clue to identify inappropriate use of PPIs and improve appropriateness of prescribing.

OBJECTIVE: To investigate the association of polypharmacy and physical performance measures in a sample of elderly patients aged ≥65 years admitted to acute care hospitals. DESIGN, SETTING AND PARTICIPANTS: Prospective study conducted among 1123 hospitalized older adults participating to the CRiteria to Assess Appropriate Medication Use among Elderly Complex Patients (CRIME) project. MEASUREMENTS: Physical performance was measured at hospital admission by the 4-meter walking speed (WS) and the grip strength (GS). Polypharmacy was defined as the use of ≥10 drugs during hospital stay. RESULTS: Mean age of 1123 participants was 81.5±7.4 years and 576 (51.3%) were on polypharmacy. Prevalence of polypharmacy was higher in patients with low WS and GS. After adjusting for potential confounders, participants in the highest tertile of WS were less likely to be on polypharmacy as compared with those in the lowest tertile (OR 0.58; 95% CI 0.35 - 0.96). Similarly, participants in the highest tertile of GS had a significantly lower likelihood of polypharmacy as compared with those in the lowest tertile (OR 0.55; 95% CI 0.36 - 0.84). When examined as continuous variables, WS and GS were inversely associated with polypharmacy (WS: OR 0.77 per 1 SD increment; 95% CI 0.60 - 0.98; GS: OR 0.71 per 1 SD increment; 95% CI 0.56 - 0.90). CONCLUSION: Among hospitalized older adults WS and GS are inversely related to polypharmacy. These measures should be incorporated in standard assessment of in-hospital patients.
