Without preventative strategies, the burden of dementia is likely to increase rapidly worldwide. Primary prevention approaches involve modifying risk factors before symptoms of cognitive impairment develop. This review systematically assesses Randomised Controlled Trials (RCTs) and reviews of RCTs for their effectiveness in primary prevention. We searched Medline, the Cochrane Library, Web of Science and Psych-Info for relevant studies using pre-determined keywords. Both non-pharmacological and pharmacological interventions were considered. Inclusion criteria were sample size greater or equal to 50, at least 6 months of follow-up, and participants with no cognitive impairment at baseline. Outcomes included dementia incidence, cognitive decline and cognitive function. Study quality was rated using the Jadad criteria. Thirty-nine studies, 17 non-pharmacological and 22 pharmacological, were included. Results were heterogeneous across interventions and studies, with few significant effects. Studies investigating physical activity and calcium channel blocker treatment demonstrated significant effects in preventing cognitive decline. There were no conclusive results demonstrating overall capacity of assessed interventions to reduce risk of dementia. The review provides an overview of the current literature, and identifies areas in need of further research.

BACKGROUND: Both subciliary and transconjunctival approaches have been used for decades to visualise the site of the maxillofacial fracture. The most common complication following those procedures is lower eyelids malposition. AIM: This meta-analysis will analyse which approach (subciliary and transconjunctival approaches) is more favourable to decrease lower eyelids malposition incidence. METHOD: This meta-analysis was conducted based on PRISMA guidelines. The electronic search was conducted using keywords (“Lower Eyelids Malposition” OR “Complications” OR “Ectropion” OR “Entropion”) AND (Transconjunctival) AND (Subciliary) AND (Maxillofacial Fractures) in PubMed, The Cochrane Library, and Directory of Open Access Journal (DOAJ). This review included full-text studies (observational and randomised controlled trials) in English comparing subciliary and transconjunctival approach in patients with maxillofacial fractures in the last 10 years. The data collected were the type of fractures and approaches, ectropion and entropion incidence as well as follow-up duration. The risk of bias was assessed using Joanna Briggs Institute critical appraisal checklist. Statistical analysis was done using Review Manager 5.3 (Cochrane, Denmark). RESULT: This study included 3 cohort studies and 2 Randomized Controlled Trial (RCT) studies from 2012 to 2017 with a total of 574 samples. Subciliary approach had a significant higher ectropion incidence when compared to transconjunctival approach (RR = 4.64, 95% CI: 1.68-12.81, p = 0.003). There was also a significant reduction of entropion incidence in patients with subciliary approach compared to transconjunctival approach (RR = 0.16, 95% CI: 0.04 – 0.69, p = 0.01). CONCLUSION: There was no superiority between one procedure toward another since each procedure related to different lower eyelids malpositions.

Background: Cognitive Training (CT) has demonstrated some benefits to cognitive and psychosocial function in Mild Cognitive Impairment (MCI) and early dementia, but the certainty related to those findings remains unclear. Therefore, understanding the mechanisms by which CT improves cognitive functioning may help to understand the relationships between CT and cognitive function. The purpose of this review was to identify the evidence for neuroimaging outcomes in studies of CT in MCI and early Alzheimer’s Disease (AD). Methods: Medline, Embase, Web of Science, PsycINFO, CINAHL, and The Cochrane Library were searched with a predefined search strategy, which yielded 1778 articles. Studies were suitable for inclusion where a CT program was used in patients with MCI or AD, with a structural or functional Magnetic Resonance Imaging (MRI) outcome. Studies were assessed for quality using the Downs and Black criteria. Results: Medline, Embase, Web of Science, PsycINFO, CINAHL, and The Cochrane Library were searched with a predefined search strategy, which yielded 1778 articles. Studies were suitable for inclusion where a CT program was used in patients with MCI or AD, with a structural or functional Magnetic Resonance Imaging (MRI) outcome. Studies were assessed for quality using the Downs and Black criteria. Conclusions: CT resulted in variable functional and structural changes in dementia, and conclusions are limited by heterogeneity and study quality. Larger, more robust studies are required to correlate these findings with clinical benefits from CT.

ABSTRACT Objective: Subjective cognitive decline (SCD) and mild cognitive impairment (MCI) in Parkinson’s disease (PD) are considered as the risk factors for dementia (PDD). Posterior cortically based functions, such as visuospatial and visuoperceptual (VS-VP) processing, have been described as predictors of PDD. However, no investigations have focused on the qualitative analysis of the Judgment of Line Orientation Test (JLOT) and the Facial Recognition Test (FRT) in PD-SCD and PD-MCI. The aim of this work was to study the VS-VP errors in JLOT and FRT. Moreover, these variables are considered as predictors of PDD. Method: Forty-two PD patients and 19 controls were evaluated with a neuropsychological protocol. Patients were classified as PD-SCD and PD-MCI. Analyses of errors were conducted following the procedure described by Ska, Poissant, and Joanette (1990). Follow-up assessment was conducted to a mean of 7.5 years after the baseline. Results: PD-MCI patients showed a poor performance in JLOT and FRT total score and made a greater proportion of severe intraquadrant (QO2) and interquadrant errors (IQO). PD-SCD showed a poor performance in FRT and made mild errors in JLOT. PD-MCI and QO2/IQO errors were independent risk factors for PDD during the follow-up. Moreover, the combination of both PD-MCI diagnosis and QO2/IQO errors was associated with a greater risk. Conclusions: PD-MCI patients presented a greater alteration in VS-VP processing observable by the presence of severe misjudgments. PD-SCD patients also showed mild difficulties in VS-SP functions. Finally, QO2/IQO errors in PD-MCI are a useful predictor of PDD, more than PD-MCI diagnosis alone.

AUTHORS:Kerstin Johansson, Karolina Thömkvist, Ingmar Skoog and Sacuiu SF* (*presenter)OBJECTIVE:To determine the effects of electroconvulsive therapy (ECT) in major depression in relation to the development of dementia during long-term follow-up.METHOD:In an observational clinical prospective study of consecutive patients 70 years and older diagnosed with major depression at baseline 2000-2004 (n=1090), who were free of dementia and received antidepressant treatment, with or without ECT, we sought to determine if cognitive decline (mild cognitive impairment and dementia) during 15 -year follow-up was associated with receiving ECT at baseline. The control group was selected among the participants in the Gothenburg H70 Birth Cohort Studies matched by age group and sex 1:1.RESULTS:Among patients with affective syndromes 7% received ECT. During follow-up, 157 patients were diagnosed with dementia, equal proportions among those who received ECT (14.5%) and those who did not receive ECT (14.5%). The relation between ECT and cognitive decline remained non-significant irrespective antidepressive medication or presence of mild cognitive impairment at baseline.CONCLUSION:Preliminary results indicate that ECT was not associated with the development of cognitive decline in the long-term in a hospital-based cohort of 70+ year-olds. The results remain to verify against controls from a representative community sample.

ABSTRACTBackground: Mild cognitive impairment (MCI) is a relatively common condition and rates of diagnosis are likely to increase in the near future. Little is known about the experiences of patients with MCI and their carers nor about the most appropriate interventions to support this group.Methods: The existing literature on this topic up to July 2011 was identified via systematic searches of the Embase and Medline databases, the Cochrane Library and relevant sections of the National Electronic Library for Health. The main search term “mild cognitive impairment” was used in combination with other relevant terms. The reference lists of reviewed articles were also examined for any additional papers of significance. Papers identified by this method were examined and those deemed relevant were included in this review.Results: Twenty-one suitable papers were identified for inclusion in this review, a relatively small number. The studies reviewed suggest that patients with MCI and their carers face a variety of practical and emotional challenges. No interventional studies of support have been undertaken, but the authors of relevant observational studies have suggested provision of information, psychosocial support and strategies to enhance patient interaction with carers and social contacts.Conclusions: MCI results in significant challenges for both patients and their carers. Further work is required in order to establish the best way to help patients and carers meet these challenges.

Abstract Background Evidence on follow-up duration for patients with sporadic pheochromocytomas is absent, and current guidelines of the European Society of Endocrinology, American Association of Clinical Endocrinologists and Endocrine Surgeons, and the Endocrine Society are ambiguous about the appropriate duration of follow-up. The aim of this systematic review and meta-analysis is to evaluate the recurrence rate of sporadic pheochromocytomas after curative adrenalectomy. Materials and Methods A literature search in PubMed, Embase, and the Cochrane Library was performed. A study was eligible if it included a clear report on the number of sporadic patients, recurrence rate, and follow-up duration. Studies with an inclusion period before 1990, <2 years of follow-up, <10 patients, and unclear data on the sporadic nature of pheochromocytomas were excluded. A meta-analysis on recurrence was performed provided that the heterogeneity was low (I2 < 25%) or intermediate (I2 26–75%). Hozo’s method was used to calculate weighted mean follow-up duration and weighted time to recurrence with combined standard deviations (SDs). Results A total of 13 studies, including 430 patients, were included in the synthesis. The meta-analysis results describe a pooled recurrence rate after curative surgery of 3% (95% confidence interval: 2–6%, I2 = 0%), with a weighted mean time to recurrence of 49.4 months (SD = 30.7) and a weighted mean follow-up period of 77.3 months (SD = 32.2). Conclusions This meta-analysis shows a very low recurrence rate of 3%. Prospective studies, including economical and health effects of limited follow-up strategies for patients with truly sporadic pheochromocytomas should be considered.

ObjectivesCommunity violence bears significant human and economic costs. Furthermore, victims requiring ED treatment are at a greater risk of violent reinjury, arrest due to perpetration and violent death. We aimed to evaluate the effectiveness of ED-based violence intervention programmes (EVIPs), which aim to reduce future violence involvement in these individuals.MethodsWe performed a systematic literature review searching MEDLINE, Embase, Cumulative Index of Nursing and Allied Health Literature, PsycINFO, The Cochrane Library and Web of Science, in addition to hand-searching. Randomised controlled trials (RCTs) were included if they enrolled victims of community violence requiring ED treatment, evaluated interventions taking place in the ED and used violent revictimisation, arrests or intermediate outcome measures as endpoints. We included trials that had a Jadad score of 2 or above.Results297 records were identified, and 13 articles were included in our final qualitative analysis, representing 10 RCTs and 9 different EVIPs. The risk of selection bias was low; the risk of performance, detection and attrition bias was moderate. 9 out of 13 papers reported statistically significant improvements in one or more outcome measures related to violence, including violent reinjury and arrests due to violence perpetration.ConclusionThe results of this literature review show that EVIPs may be capable of reducing violent reinjury and arrests due to violence perpetration. Larger RCTs, taking place in different regions, in different age groups and using different techniques, are justified to determine which conditions may be required for success and whether EVIPs are generalisable.

We investigated the association between poststroke cognitive impairment and a specific effective network connectivity in the prefrontal–basal ganglia circuit. The resting-state effective connectivity of this circuit was modeled by employing spectral dynamic causal modeling in 11 poststroke patients with cognitive impairment (PSCI), 8 poststroke patients without cognitive impairment (non-PSCI) at baseline and 3-month follow-up, and 28 healthy controls. Our results showed that different neuronal models of effective connectivity in the prefrontal–basal ganglia circuit were observed among healthy controls, non-PSCI, and PSCI patients. Additional connected paths (extra paths) appeared in the neuronal models of stroke patients compared with healthy controls. Moreover, changes were detected in the extra paths of non-PSCI between baseline and 3-month follow-up poststroke, indicating reorganization in the ipsilesional hemisphere and suggesting potential compensatory changes in the contralesional hemisphere. Furthermore, the connectivity strengths of the extra paths from the contralesional ventral anterior nucleus of thalamus to caudate correlated significantly with cognitive scores in non-PSCI and PSCI patients. These suggest that the neuronal model of effective connectivity of the prefrontal–basal ganglia circuit may be sensitive to stroke-induced cognitive decline, and it could be a biomarker for poststroke cognitive impairment 3 months poststroke. Importantly, contralesional brain regions may play an important role in functional compensation of cognitive decline.

Background. Evidence remains mixed as to the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in treating mild cognitive impairment (MCI) in patients with Parkinson’s disease (PD). Objective. In this study, we examined the short- and long-term effects of patterned rTMS. Methods. We randomly assigned 35 patients with PD with MCI to two groups. One group received intermittent theta burst stimulation (iTBS; n = 20), and the other received its sham counterpart (n = 15). The stimulations were applied over the left dorsolateral prefrontal cortex for 10 consecutive weekdays. Measurements based on the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and Montreal Cognitive Assessment (MoCA) were conducted at three time points: at baseline, immediately after the last intervention and at 3-month follow-up. Each patient received a 99mTc-TRODAT-1 single-photon emission computed tomography (SPECT) brain scan at baseline. Results. The iTBS group exhibited significantly greater improvement than the sham group did in total RBANS and MoCA scores ( p < .001 for both) immediately after intervention and at the 3-month follow-up. Radiotracer uptake in the bilateral basal ganglion in baseline SPECT was positively correlated with response to iTBS conditioning with respect to improvements in MoCA scores ( p = .021). Conclusion. This randomised controlled trial provides evidence that a consecutive iTBS protocol can achieve a persistent and wide-ranging therapeutic effect in patients with PD with MCI.
