Background and Purpose-To evaluate the relationship between arterial stiffness and cognitive function in a population of elderly subjects reporting memory loss. Methods-We studied the association between cognitive function and arterial stiffness in 308 consecutive elderly subjects attending a geriatric outpatient clinic reporting memory impairment. Subjects were classified into 4 categories according to neuropsychological evaluation: normal cognitive function, mild cognitive impairment (MCI), Alzheimer disease (AD), or vascular dementia (VaD). Arterial stiffness was evaluated by carotid-femoral pulse wave velocity (PWV) measurement using Complior. Results-In this population, 78Ϯ8 years of age (women 64%), AD was present in 41%, VaD in 6%, MCI in 27%, and 26% of subjects had normal cognitive function. After adjustment for age, gender, systolic blood pressure, education level, cardiovascular diseases, and antihypertensive therapy, a significant association was observed between PWV and cognitive status (PϽ0.0001). PWV appears significantly higher in subjects with VaD (15.2Ϯ3.9 m/s) or AD (13.3Ϯ2.9 m/s) than in those without cognitive impairment (11.5Ϯ2.0 m/s; PϽ0.001). Moreover, PWV was higher in subjects with MCI (12.6Ϯ2.6 m/s) than in those without cognitive impairment (11.5Ϯ2.0 m/s; Pϭ0.01). For each 2 m/s increment in PWV, the adjusted odds ratio (95% CI) was 1.
Massive irreparable rotator cuff tears remain a challenging condition during daily clinical practice. Irreversible fatty infiltration of muscles and excessive chronic retraction of tendons predispose to high failure rates of their surgical treatment. Superior capsular reconstruction with either fascia lata autograft or a dermal allograft patch is a newly described solution that could prevent superior humeral head migration and restore the anteroposterior shoulder muscle force couples. The purpose of this article is to propose a technical modification of superior capsular reconstruction using long head of the biceps tendon autograft. The tendon's insertion into the glenoid is left intact, whereas laterally, it is tenotomized, transferred, and sutured with anchors onto the footprint of the supraspinatus tendon acting as a superior static stabilizer of the shoulder joint. Although this surgical modification has theoretical biological advantages, could be performed with the least technical demands, and simplifies the original demanding procedure, further prospective studies with large cohort populations and long-term follow-up are necessary to establish its effectiveness.
PurposeMild cognitive impairment (MCI) is associated with a higher risk of dementia and is becoming a topic of interest for pharmacological and nonpharmacological interventions. With advances in technology, computer-based cognitive exercises are increasingly integrated into traditional cognitive interventions, such as cognitive training. Another type of cognitive intervention involving technology use is cognitive engagement, consisting of involving participants in highly motivational and mentally challenging activities, such as learning to use a form of new digital technology. This study examined the feasibility and acceptability of a computerized cognitive stimulation (CCS) program and a computerized cognitive engagement (CCE) program, and then compared their effects in older adults with MCI.Patients and methodsIn this randomized study, data from 19 MCI patients were analyzed (n=9 in CCS and n=10 in CCE). The patients attended a group weekly session for a duration of 3 months. Assessments of cognitive and psychosocial variables were conducted at baseline (M0) and at the end of the programs (M3).ResultsAll of the participants attended the 12 sessions and showed a high level of motivation. Attrition rate was very low (one dropout at M3 assessment). At M3, the CCS participants displayed a significant improvement in part B of the Trail Making Test (TMT-B; p=0.03) and self-esteem (p=0.005), while the CCE participants showed a significant improvement in part A of the Trail Making Test (TMT-A; p=0.007) and a higher level of technology acceptance (p=0.006). The two groups did not differ significantly (p>0.05) in cognitive and psychosocial changes after the intervention. However, medium effect sizes (Cohen’s d=0.56; 95% CI =−0.43:1.55) were found on the free recall, favoring the CCS group, as well as on TMT-A (d=0.51; 95% CI =−0.48:1.49) and technology acceptance (d=−0.65; 95% CI =−1.64:0.34), favoring the CCE group.ConclusionBoth interventions were highly feasible and acceptable and allowed improvement in different aspects of cognitive and psychosocial functioning in MCI subjects.
The interest in robot-assisted therapies (RAT) for dementia care has grown steadily in recent years. However, RAT using humanoid robots is still a novel practice for which the adhesion mechanisms, indications and benefits remain unclear. Also, little is known about how the robot's behavioral and affective style might promote engagement of persons with dementia (PwD) in RAT. The present study sought to investigate the use of a humanoid robot in a psychomotor therapy for PwD. We examined the robot's potential to engage participants in the intervention and its effect on their emotional state. A brief psychomotor therapy program involving the robot as the therapist's assistant was created. For this purpose, a corpus of social and physical behaviors for the robot and a “control software” for customizing the program and operating the robot were also designed. Particular attention was given to components of the RAT that could promote participant's engagement (robot's interaction style, personalization of contents). In the pilot assessment of the intervention nine PwD (7 women and 2 men, M age = 86 y/o) hospitalized in a geriatrics unit participated in four individual therapy sessions: one classic therapy (CT) session (patient- therapist) and three RAT sessions (patient-therapist-robot). Outcome criteria for the evaluation of the intervention included: participant's engagement, emotional state and well-being; satisfaction of the intervention, appreciation of the robot, and empathy-related behaviors in human-robot interaction (HRI). Results showed a high constructive engagement in both CT and RAT sessions. More positive emotional responses in participants were observed in RAT compared to CT. RAT sessions were better appreciated than CT sessions. The use of a social robot as a mediating tool appeared to promote the involvement of PwD in the therapeutic intervention increasing their immediate wellbeing and satisfaction.
The aim of our study was to investigate whether depression assessed by different markers predicts the risk of incident dementia in elderly individuals. Data was derived from the 3C cohort study conducted in community-dwelling individuals aged 65 years and over, randomly recruited from electoral rolls of three French areas and followed up for four years (1999-2001 through 2004) with assessments every 2 years. The study sample comprised 7989 dementia-free individuals (mean age, 74.0 years; 61% women) assessed at baseline for current or past Major Depressive Episodes (MDE) based on MDE module of the Mini International Neuropsychiatric Interview, self-reported lifetime treated depression, and level of depressive symptoms using the Center for Epidemiologic Studies-Depression Scale. Fully adjusted Cox proportional hazards models were applied to examine the risk of incident dementia associated with these markers of depression. MDE and self-reported lifetime treated depression did not increase incident dementia risk. Conversely, high level of depressive symptoms at baseline was associated with a 50% increased risk of dementia (adjusted Hazard Ratio [HR], 1.5; 95% Confidence interval [CI], 1.2-2.2). This result was driven by a five-fold increased risk of vascular dementia (HR, 4.8; 95% CI, 2.2-10.7; p < 0.0001), whereas there was no increased risk of Alzheimer's disease (1.0; 0.7-1.6). In elderly individuals, high level of depressive symptoms is predictive of vascular dementia within a few years. This close temporal association suggests that depression is less a risk factor for than a prodromal symptom of vascular dementia.
In a large sample of elderly individuals from the general population, depressive individuals had lower blood pressure values than nondepressive ones, independent of medications and of history of cardiovascular events.
BackgroundBehavioral and psychological symptoms of dementia (BPSD) affect patients’ daily life and subjective well-being. International recommendations stress nonpharmacological interventions as first-line treatment. While newer psychosocial initiatives adapted to geriatric populations based on social robot therapy have emerged, to our knowledge, no studies on differential efficacy depending on BPSD profiles have been conducted yet.ObjectivesThis pilot study examined the impact of short exposure to a social robot (Paro®) on the subjective emotional well-being of patients with major neurocognitive disorder as well as its impact on differential effects for 3 BPSD profiles.MethodsSeventeen patients with major NCD with apathy (n=6), depression (n=7), and agitation (n=4) were recruited. The intervention was composed of four 15-minute individual sessions. Exposure occurred without the simultaneous presence of a health care provider. A pre–post assessment of emotional well-being was conducted with the International Positive and Negative Affect Schedule Short-Form, which measures positive and negative affectivity.ResultsOverall findings showed a significant increase of positive affectivity (p=0.02). Subgroup analysis demonstrated that agitated patients reduced negative affectivity significantly more than depressed patients (p=0.03). Results also confirmed users’ overall acceptability of the robot.ConclusionThese findings support the usefulness of brief interactive sessions with the Paro robot for elderly patients with major NCD. These preliminary results encourage further research focused on brief interventions using social robotics, as well as on their specific benefits depending on the behavioral typology of patients with neurocognitive disorders.
