BACKGROUND: Variants in triggering receptor expressed on myeloid cells 2 (TREM2) are associated with increased Alzheimer's disease (AD) risk. Recent studies have reported inconsistent peripheral TREM2 mRNA expression levels and relationship with cognitive scores in AD and mild cognitive impairment (MCI). Additionally, no study has examined the association of peripheral TREM2 levels with neuroimaging measures in AD and MCI. OBJECTIVE: To determine peripheral TREM2 mRNA levels in AD, amnestic MCI (aMCI) and healthy controls, and the association with cognitive performance and brain structural changes...

Despite widespread use, there have been few investigations into the neuroanatomical correlates of the Montreal Cognitive Assessment (MoCA). In a sample of 138 consecutive patients presenting with cognitive complaints, we report significant correlations between lower MoCA memory scores and smaller hippocampal volumes (r = 0.36-0.41, p < 0.001). We also report that the newly devised memory index score, designed to better capture encoding deficits than the standard delayed recall score, was not significantly better for predicting hippocampal volume...

BACKGROUND: Cognitive deficits are common, long-term sequelae in children and adolescents with congenital heart disease (CHD) who have undergone surgical palliation. However, there is a lack of a validated brief cognitive screening tool appropriate for the outpatient setting for adolescents with CHD. One candidate instrument is the Montreal Cognitive Assessment (MoCA) questionnaire. OBJECTIVE: The purpose of the research was to validate scores from the MoCA against the General Memory Index (GMI) of the Wide Range Assessment of Memory and Learning, 2nd Edition (WRAML2), a widely accepted measure of cognition/memory, in adolescents and young adults with CHD...

BACKGROUND: A cross sectional study was conducted in a group of 317 subjects older than 60 in Malaysia, aimed to determine risk factors associated with cognitive impairment in older adults, focusing on trace elements and DNA damage. METHOD: Cognitive decline was determined by Montreal Cognitive Assessment (MoCA). Oxidative stress markers (malondialdehyde-MDA and superoxide dismutase-SOD) were determined and DNA damage was assayed using Alkaline Comet Assay. Toenail samples were taken and analyzed using ICP-MS to determine trace element levels...

PURPOSE: Cystic Fibrosis (CF) is the most common genetic disorder and, with improved survival, glucose abnormalities have emerged as a major comorbidity. Proprotein convertase subtilisin/kexin type 9 (PCSK9), a regulator of plasma LDL-cholesterol homeostasis, is associated with lipid and glucose metabolism in healthy individuals. Here we report on the link between PCSK9 and markers of metabolism in CF. METHODS: Cross-sectional analysis was performed on CF patients (≥ 18 years, N=94) from the Montreal Cohort, without known diabetes, and on healthy individuals (N=19)...

Zhenqiu He, Nan Xu, Sihua Qi
BACKGROUND: Cognitive function impairment is one of the most common complications in elderly patients after surgery, and an ideal nonpharmacological therapy has not yet been identified. Thus, we hypothesized that remote ischemic preconditioning could improve cognitive functions in elderly patients after surgery and investigated the mechanism underlying this effect. METHODS: Ninety patients classified as American Society of Anaesthesiologists (ASA) physical status of 2 or 3 and aged 65 to 75 years who were scheduled for elective colon surgery under general anesthesia were randomly allocated to either a remote ischemic preconditioning group (Group R, n = 45) or a control group (Group C, n = 45)...

Elevated oxidative stress is known to play an important role in development of depression and cognitive dysfunction. To date, thioredoxin (TRX), an antioxidant protein, has been investigated as a marker for psychiatric disorders such as schizophrenia, bipolar disorder and autism but its relationship with depression is yet to be unknown. The aim of this study is to detect the TRX levels in patients with treatment-resistant depression (TRD), analyse the effect of rTMS (repetitive transcranial magnetic stimulation) application on TRX levels and display the relationship of TRX with cognitive areas...

A large proportion of stroke patients are unable to return to work (RTW), although figures vary greatly. A total of 121 mild-to-moderate stroke patients, who had a paid job at the time of their stroke were included (a) to quantify RTW and work satisfaction one-year post-stroke (using the Utrecht Scale for Evaluation of Rehabilitation-Participation) and (b) to determine factors predicting RTW post-stroke, based on stroke-related, personal and neuropsychological variables. Half of the patients were not in work (28%) or were working less (22%) than pre-stroke...

BACKGROUND AND PURPOSE: Functional outcome after stroke is often only evaluated using the modified Rankin Scale, which primarily assesses activities of daily living. Stroke patients may experience difficulties with social reintegration and mental functions, feel isolated, and experience poor quality of life, even after physical recovery is complete. Functional assessments based solely on activity limitations may not be able to capture the full range of problems experienced by stroke survivors...

BACKGROUND: There is a relative lack of longitudinal studies investigating stroke-specific outcomes and quality of life (QOL). This study aimed to identify which factors (level of disability, cognitive functioning, depressive symptoms, physical activity, and work and social engagement) were independently associated with each stroke-specific domain of QOL, adjusting for age and gender, at 3 months and 12 months post-stroke in an Australian cohort. METHOD: Survivors of ischemic stroke were recruited from 18 sites of the STroke imAging pRevention and Treatment (START) longitudinal cohort study...

INTRODUCTION: Despite the considerable prevalence of cognitive impairment in substance-using populations, there has been little investigation of the utility of cognitive screening measures within this context. In the present study the accuracy of three cognitive screening measures in this population was examined-the Mini-Mental State Examination (MMSE), the Addenbrooke's Cognitive Examination-Revised (ACE-R), and the Montreal Cognitive Assessment (MoCA). METHOD: A sample of 30 treatment-seeking substance users and 20 healthy individuals living in the community were administered the screening measures and a neuropsychological battery (NPB)...

BACKGROUND: Providing patient-centered healthcare requires that patient needs, preferences, and valued outcomes are more fully integrated into all decisions. Patient reported outcome measures (PROs) provide unique information from the patient perspective on overall health, symptoms, burden, and treatment response. OBJECTIVE: We sought to describe applications of PROs in clinical settings and considerations for implementation from the perspectives of PRO researchers, clinicians, administrators, policy makers, and patients attending a multidisciplinary meeting...

BACKGROUND: Patient reported outcomes (PRO) are collected with consent for care, however using the data for any other purpose requires consent for that additional purpose, or the anonymization of the data. Collecting explicit consent to use this data for secondary purposes, before the patient completes a PRO, can also bias the responses. OBJECTIVE: We consider the ethical and security issues related to the collection of data at the point of care or in the population, and the aggregation and integration of PRO data with administrative databases to facilitate decision-making and comparative effectiveness research...

BACKGROUND: Given that the goal of healthcare systems is to improve and maintain the health of the populations they serve, the indicators of performance must include outcomes that are meaningful to patients. The growth of health technologies provides an unprecedented opportunity to integrate the patient voice into clinical care by linking electronic health records (EHR) to patient-reported outcome (PRO) data collection. However, PRO data must be relevant, meaningful, and actionable for those who will have to invest the time and effort to collect it...

BACKGROUND: PRO data are beneficial to a range of stakeholders including patients, clinicians, researchers, national funding and regulatory agencies, health system administrators, and policymakers. OBJECTIVE: Because stakeholders represent diverse groups and needs, it is challenging to reach consensus on how to advance PRO development and harmonize data across settings to enable use for multiple secondary purposes. Collaborative national networks can facilitate the sharing of expertise, resources and necessary infrastructure; create development, use, and reporting standards; optimize formats to efficiently store and transfer data; and disseminate tools and information for widespread uptake...
