Dietary antioxidants as potential pharmacological agents for ischemic stroke.

Acute ischemic stroke is a leading cause of death and severe disability in industrialised countries and also in many developing countries. An excessive amount of free radicals is generated during cerebral ischemia, which significantly contributes to brain damage. Therefore, an increasing interest has been devoted to the potential benefits of antioxidant compounds in ischemic stroke patients. In this review, we examined the most relevant observational studies concerning the relationship between dietary antioxidants and ischemic stroke as well as clinical trials investigating the effects of single or multiple antioxidant supplementation in the prevention or treatment of acute ischemic stroke. Furthermore, we reviewed the most promising antioxidant compounds, i.e. dehydroascorbic acid, alpha-tocotrienol, gamma-tocopherol, flavonoids, resveratrol and gingko biloba, tested in animal models of acute ischemic stroke. Finally, we carefully evaluated the reasons for the discrepancy between experimental and clinical studies, and provided recommendations to improve the translation of the results obtained in animal models to patients with acute ischemic stroke.

Systematic review of systematic reviews of non-pharmacological interventions to treat behavioural disturbances in older patients with dementia. The SENATOR-OnTop series

Objective To provide an overview of non-pharmacological interventions for behavioural and psychological symptoms in dementia (BPSD). Design Systematic overview of reviews. Data sources PubMed, EMBASE, Cochrane Database of Systematic Reviews, CINAHL and PsycINFO (2009–March 2015). Eligibility criteria Systematic reviews (SRs) that included at least one comparative study evaluating any non-pharmacological intervention, to treat BPSD. Data extraction Eligible studies were selected and data extracted independently by 2 reviewers. The AMSTAR checklist was used to assess the quality of the SRs. Data analysis Extracted data were synthesised using a narrative approach. Results 38 SRs and 142 primary studies were identified, comprising the following categories of non-pharmacological interventions: (1) sensory stimulation interventions (12 SRs, 27 primary studies) that encompassed: acupressure, aromatherapy, massage/touch therapy, light therapy and sensory garden; (2) cognitive/emotion-oriented interventions (33 SRs; 70 primary studies) that included cognitive stimulation, music/dance therapy, dance therapy, snoezelen, transcutaneous electrical nerve stimulation, reminiscence therapy, validation therapy, simulated presence therapy; (3) behaviour management techniques (6 SRs; 32 primary studies) and (4) other therapies (5 SRs, 12 primary studies) comprising exercise therapy, animal-assisted therapy, special care unit and dining room environment-based interventions. Music therapy was effective in reducing agitation (SMD, −0.49; 95% CI −0.82 to −0.17; p=0.003), and anxiety (SMD, −0.64; 95% CI −1.05 to −0.24; p=0.002). Home-based behavioural management techniques, caregiver-based interventions or staff training in communication skills, person-centred care or dementia care mapping with supervision during implementation were found to be effective for symptomatic and severe agitation. Conclusions A large number of non-pharmacological interventions for BPSD were identified. The majority of the studies had great variation in how the same type of intervention was defined and applied, the follow-up duration, the type of outcome measured, usually with modest sample size. Overall, music therapy and behavioural management techniques were effective for reducing BPSD.

Underrecognition and Undertreatment of Dementia in Italian Nursing Homes

OBJECTIVE To determine the prevalence of dementia diagnoses and the use of antidementia drugs in a cohort of Italian older nursing home (NH) residents. DESIGN Cross-sectional study. SETTING The NH residents participating in 2 studies: the U.L.I.S.S.E. study and the Umbria Region survey. PARTICIPANTS A total of 2215 nursing home residents. MEASUREMENT Each resident underwent a comprehensive geriatric assessment at baseline by means of the RAI MDS 2.0. Dementia diagnosis was based on ICD-9 codes. RESULTS The prevalence of dementia diagnosis according to ICD-9 codes was 50.7% (n = 1123), whereas 312 subjects had cognitive impairment with a cognitive performance scale score ≥3 without a diagnosis of dementia. Only 56 NH residents were treated (5% of the sample) and the main drugs used were cholinesterase inhibitor, whereas only 1 subject was treated with memantine. Limiting our analysis to patients with mild to moderate Alzheimers disease, who are those reimbursed by the public health care system for receiving antidementia drugs, the percentage rose to 11.3%. CONCLUSION These findings demonstrate a high rate of underdiagnosis and undertreatment of dementia in Italian NH residents. Potential explanations include the lack of systematic assessment of cognitive functions, the limitations to antidementia drug reimbursement, the complexity of the reimbursement procedure itself, and the high prevalence of patients with severe dementia. Older NH residents still lack proper access to state-of-the-art diagnosis and treatment for a devastating condition such as dementia.

Inappropriate Drug Prescriptions among Older Nursing Home Residents: The Italian Perspective

Older people take up a large proportion of health care, including drugs, and evidence shows that drug prescribing to this group is often inappropriate. Negative consequences of potential inappropriate drug prescription (PIDP) include adverse drug events, high healthcare service utilization and high costs for the patients and society. Although nursing home residents are the most vulnerable persons exposed to PIDP, few observational studies have investigated the prevalence, the factors associated with and the consequences of PIDP. Epidemiological studies assessing PIDP mainly based on the Beers’ criteria showed that approximately half of US and Canadian nursing home residents have at least one PIDP in this setting. The most frequent inappropriate prescriptions concern neuroleptics and long-term benzodiazepines. Nursing home residents aged 80 years or more, those taking a low number of drugs, cognitive or communication problems are less exposed to PIDP compared with residents younger than 80 years, living in facilities with a high number of beds and a lower registered nurse-to-resident ratio. In European countries, the prevalence of PIDP among older nursing home residents was comparable to or higher than that observed in US and Canadian nursing homes. To date, the issue of PIDP has never been investigated in a representative sample of Italian nursing home residents. In a preliminary study performed by our group in 496 nursing home residents randomly selected from 40 nursing homes in Umbria, the prevalence of residents taking at least one or two inappropriate medications was 28% and 7%, respectively. The prevalence of PIDP considering diagnosis (18%) as well as those regardless of diagnosis (17%), as determined by Beers’ criteria, were equally distributed in older Italian nursing home residents and no difference was found between sexes. Overall, this review reveals that the prevalence of PIDP is high in both North American and European nursing homes and highlights the urgent need for intervention trials testing strategies to reduce the health and social burden of PIDP.

Validation of the Italian version of the falls efficacy scale international (FES-I) and the short FES-I in community-dwelling older persons.

Fear of falling (FF) is a common problem in older persons. FF negatively affects the quality of life by generating anxiety, loss of confidence and of self-efficacy, and, ultimately, activity restriction and increased risk of falling. The FES-I and Short FES-I are two instruments developed to assess FF in older persons which have been already validated in some European countries. Our objectives are to develop the Italian version of FES-I and the Short FES-I and to validate them in older persons. The back translation protocol adopted by the ProFaNE group was used to translate both scales from English to Italian. Participants were 157 community-dwelling persons aged>65 years who underwent comprehensive geriatric assessment, including a structured interview concerning FF, and were administered the FES-I and the Short FES-I. Both scales were re-tested after 4 weeks in 151 persons. FES-I and Short FES-I had high internal validity and test-retest reliability. The Short FES-I is highly comparable with the FES-I. We conclude that the FES-I and the Short FES-I are excellent instruments to asses FF in Italian older subjects and they may be used in future research projects and clinical trials.

The Prevention of Adverse Drug Reactions in Older Subjects

Adverse drug reactions (ADRs) are a public health problem in older subjects, being responsible for a significant morbidity, disability and mortality. Older subjects are more susceptible to develop ADRs mainly due to polypharmacy, multimorbidity and inappropriate prescribing. The prevention of these drug related negative events represents an important aim for physicians treating older patients. Several strategies could potentially be employed, including state of the art education of medical students and physicians concerning principles of geriatric medicine and appropriate prescription in older subjects, reduction of inappropriate drug use by means of computerized decision support systems, pharmacist involvement and comprehensive geriatric assessment, and finally the identification of at risk older patients. However, there is currently a lack of scientific evidence demonstrating that these strategies can achieve a reduction in ADRs and therefore future intervention studies should be performed to evaluate the best intervention to decrease the burden of drug related problems in the older population.

Effectiveness of Non-Pharmacological Interventions to Prevent Falls in Older People: A Systematic Overview. The SENATOR Project ONTOP Series

Background Falls are common events in older people, which cause considerable morbidity and mortality. Non-pharmacological interventions are an important approach to prevent falls. There are a large number of systematic reviews of non-pharmacological interventions, whose evidence needs to be synthesized in order to facilitate evidence-based clinical decision making. Objectives To systematically examine reviews and meta-analyses that evaluated non-pharmacological interventions to prevent falls in older adults in the community, care facilities and hospitals. Methods We searched the electronic databases Pubmed, the Cochrane Database of Systematic Reviews, EMBASE, CINAHL, PsycINFO, PEDRO and TRIP from January 2009 to March 2015, for systematic reviews that included at least one comparative study, evaluating any non-pharmacological intervention, to prevent falls amongst older adults. The quality of the reviews was assessed using AMSTAR and ProFaNE taxonomy was used to organize the interventions. Results Fifty-nine systematic reviews were identified which consisted of single, multiple and multifactorial non-pharmacological interventions to prevent falls in older people. The most frequent ProFaNE defined interventions were exercises either alone or combined with other interventions, followed by environment/assistive technology interventions comprising environmental modifications, assistive and protective aids, staff education and vision assessment/correction. Knowledge was the third principle class of interventions as patient education. Exercise and multifactorial interventions were the most effective treatments to reduce falls in older adults, although not all types of exercise were equally effective in all subjects and in all settings. Effective exercise programs combined balance and strength training. Reviews with a higher AMSTAR score were more likely to contain more primary studies, to be updated and to perform meta-analysis. Conclusions The aim of this overview of reviews of non-pharmacological interventions to prevent falls in older people in different settings, is to support clinicians and other healthcare workers with clinical decision-making by providing a comprehensive perspective of findings.

Validation of chronic obstructive pulmonary disease (COPD) diagnoses in healthcare databases: a systematic review protocol

Introduction Healthcare databases are useful sources to investigate the epidemiology of chronic obstructive pulmonary disease (COPD), to assess longitudinal outcomes in patients with COPD, and to develop disease management strategies. However, in order to constitute a reliable source for research, healthcare databases need to be validated. The aim of this protocol is to perform the first systematic review of studies reporting the validation of codes related to COPD diagnoses in healthcare databases. Methods and analysis MEDLINE, EMBASE, Web of Science and the Cochrane Library databases will be searched using appropriate search strategies. Studies that evaluated the validity of COPD codes (such as the International Classification of Diseases 9th Revision and 10th Revision system; the Real codes system or the International Classification of Primary Care) in healthcare databases will be included. Inclusion criteria will be: (1) the presence of a reference standard case definition for COPD; (2) the presence of at least one test measure (eg, sensitivity, positive predictive values, etc); and (3) the use of a healthcare database (including administrative claims databases, electronic healthcare databases or COPD registries) as a data source. Pairs of reviewers will independently abstract data using standardised forms and will assess quality using a checklist based on the Standards for Reporting of Diagnostic accuracy (STARD) criteria. This systematic review protocol has been produced in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol (PRISMA-P) 2015 statement. Ethics and dissemination Ethics approval is not required. Results of this study will be submitted to a peer-reviewed journal for publication. The results from this systematic review will be used for outcome research on COPD and will serve as a guide to identify appropriate case definitions of COPD, and reference standards, for researchers involved in validating healthcare databases. Trial registration number CRD42015029204.

Simulated presence therapy for dementia: a systematic review protocol

Introduction The majority of patients with dementia develop behavioural and psychological symptoms of dementia (BPSD). Non-pharmacological interventions are an appealing alternative for the treatment of BPSD in patients with dementia. Simulated presence therapy (SPT) is a simple and inexpensive non-pharmacological intervention that can be used to treat BPSD. We propose a Cochrane protocol for the collection and assessment of evidence concerning the efficacy of SPT to treat relevant outcomes in people with dementia. Methods and analysis We will search the following electronic databases: the Cochrane Dementia and Cognitive Improvement Groups Specialised Register MEDLINE, EMBASE, CINAHL, PsycINFO, LILACS, CENTRAL and a number of trial registers as well as grey literature sources. We will include randomised and quasi-randomised controlled trials (including cross-over studies) that evaluated SPT in people with dementia. Comparators such as usual care with no additional activity, or any activity that differs in content and approach from SPT, but is additional to usual care, will be considered. The primary outcomes of interest will comprise behavioural and psychological symptoms, as measured by relevant scales, and quality of life. Two review authors working independently and in tandem will be involved in title and abstract screening, full-text screening and data abstraction. Where possible, quantitative data will be pooled, and relative risk and mean difference with 95% CI will be employed for dichotomous and continuous data, respectively. Assessment of risk of bias will be performed using the Cochrane risk-of-bias tool and the Grades of Recommendation, Assessment, Development and Evaluation approach. Ethics and dissemination Ethics approval is not required. The final results of this systematic review will be presented to the Cochrane Library and will also be disseminated at relevant conference presentations. Trial registration number CRD42015029778.
