RESUMO

BACKGROUND AND PURPOSE: Almost half of elderly patients being consulted in memory clinics present anxiety disorders, either with or without an associated depressive syndrome. This study investigates the relationship between the level of anxiety and cognitive performance in a population complaining of memory difficulties. METHODS: The study population (n = 149) was selected from the EVATEM cohort, which included subjects aged 65 years or older. All subjects presented memory complaints and patients with depression were excluded. Anxiety level was assessed with the Hamilton Anxiety Rating Scale. A standard neuropsychological battery, including a free and cued episodic memory test, was administered to examine the different processes of verbal episodic memory, visual memory, executive, visuoconstructive and instrumental functions. RESULTS: Subjects with moderate to severe anxiety had worse performance than subjects with no anxiety in retrieval and storage processes of verbal episodic memory (respectively P = 0.004 and P = 0.02) and in visual recognition memory (P = 0.01). No relationship was found between anxiety and executive, visual-constructive or instrumental functions. CONCLUSION: Anxiety impacts several stages of verbal memory, notably the processes of storage and retrieval, and visual recognition memory within a population having cognitive complaints. This study suggests that anxiety should be considered as a factor of memory vulnerability for patients being treated in memory clinics.

RESUMO

BACKGROUND AND PURPOSE: Dementia is a leading cause of dependence amongst the aged population. Early identification of cognitive impairment could help to delay advanced stages of dependence. This study aimed at assessing the performance of three neuropsychological tests to detect cognitive disorders in elderly subjects with memory complaints. METHODS: The EVATEM study is a prospective multicentre cohort with a 1-year follow-up. Subjects with memory complaints were selected during preventive health examinations, and three neuropsychological tests (five-word, cognitive disorders examination, verbal fluency) were administered. Two groups were identified in memory clinics: (i) cognitively healthy individuals (CHI) and (ii) mild cognitive impairment or demented individuals (MCI-DI). Cross-sectional analyses were performed on data at inclusion. The relationship between the diagnosis of MCI-DI/CHI and the neuropsychological tests was assessed using logistic regressions. The performance of the neuropsychological tests, individually and combined, to detect cognitive disorders was calculated. RESULTS: Of 585 subjects, 31.11% had cognitive disorders (MCI, 176 subjects; DI, six subjects). Amongst the three tests studied, the odds ratio for MCI-DI was higher for the five-word test <10 [odds ratio 3.2 (1.81; 5.63)]. The best performance was observed when the three tests were combined: specificity 90.5% and sensitivity 42.4% compared to respectively 89.2% and 28.3% for the five-word test. CONCLUSIONS: Despite the poor sensitivity of the five-word test, it seems to be the most adapted for the diagnosis of MCI-DI in older adults with a memory complaint, in prevention centres, taking into account its high specificity and its rapid administration compared to the other tests.

RESUMO

PURPOSE: To investigate the use of a nonmydriatic digital color fundus camera and telemedicine as screening tools for age-related macular degeneration (AMD). METHODS: Nonmydriatic color fundus photography was performed on patients consulting health examination centers and transmitted by telemedicine to an ophthalmology department. Rates for different grades of AMD were calculated and also statistically related to the presence or absence of risk factors. RESULTS: Among the 1,022 patients screened, a total of 1,363 color fundus photographs were interpreted, with 80% gradable images, allowing a diagnosis of AMD in 178 photographs. Among all the gradable images, 83.7% had no AMD (grade 0). The rates of AMD at grades 1, 2, 3 and 4 were 8%, 5.6%, 2.3% and 0.4%, respectively. A statistical odds ratio was found between the presence of AMD on fundus photographs and age, familial history of AMD or prior cataract surgery. CONCLUSIONS: Nonmydriatic color fundus photography and telemedicine succeeded in screening for AMD.

RESUMO

BACKGROUND: We compared the efficacy of two viral hepatitis B and C (VHBC) screening strategies, relative to no intervention, among underprivileged people (UP) living in shelters in the Lyon area. METHODS: Eighteen of 37 shelters were randomly sampled after stratification based on the accommodation capacity and the screening centres/shelters distance. Through randomization, the S0 strategy (no intervention), the S1 strategy [group information (GI) and referral for screening] and the S2 strategy (GI and in situ screening) were each applied in six shelters. A standardized questionnaire was offered to each participant. Follow-up of positive cases was organized via the reference centre of VHBC of Lyon. RESULTS: The screening completion rate (SCR) among 1276 included subjects in S0, S1 and S2 was 1.5, 42.8 and 59.7%, respectively (P < 10(-6)). This rate was higher in S2 regardless of the sociodemographic variable considered. Odds ratios (OR) of screening completion (SC) was significantly higher in S1 versus S0, OR = 49.8 [95% confidence interval (CI): 26.1-102.1], in S2 versus S0, OR = 98.5 (95% CI: 51.9-200.8) and in S2 versus S1, OR = 2.0 (95% CI: 1.3-2.9). Age, country of birth and professional inactivity were independently associated with SC. CONCLUSIONS: Health authorities must ensure widespread screening of UP, which is more effective when conducted in shelters than in screening centres.

RESUMO

BACKGROUND: With the increasing prevalence of obesity and the risk of increased dependency among the elderly, it becomes important to characterize the link between obesity and frailty. The relationship between obesity and social deprivation would be bidirectional, with each influencing the other. OBJECTIVES: Main objective was to study the relationship between frailty as defined by Fried and obesity (Body Mass Index (BMI) and abdominal obesity). Secondary objective was to assess the relationship between frailty and social deprivation. MATERIALS AND METHODS: This was a cross-sectional study, with data collected between January 2014 and December 2015 using a senior periodic health prevention examination form used in the 4 sites of the health examination center, in Rhone, among non-institutionalized seniors (≥ 65 years). Frailty was defined according to Fried's criteria. Obesity was defined by a BMI ≥ 30 kg / m2 and a waist circumference > 88 cm for women and >102 cm for men. We studied the association between obesity according to BMI ≥ 30kg / m2 on the one hand and abdominal obesity on the other hand with frailty according to Fried. The analyzes were adjusted for gender, age, education level, not being in a relationship and social deprivation quantified by the assessment score of deprivation and health inequalities (EPICES score). RESULTS: 1593 senior health prevention examination forms were studied. According to BMI, senior women were almost twice as likely to be frail when obese (RR = 1.92, 95% CI [1.06 - 3.45], p = 0.018). The results were similar for abdominal obesity in women aged 65-74 years (RR = 2.12, 95% CI [1.03-4.35], p = 0.029). There was no relationship in men for both types of obesity. Seniors who were socially deprived were 2.7 times more likely to be frail than non-deprived seniors (adjusted RR = 2.76, 95% CI [1.808 - 4.203], p <0.001). CONCLUSIONS: Obesity (BMI ≥ 30kg / m2 and high waist circumference) was associated with increased frailty among older, non-institutionalized women who came for a periodic health prevention examination. Screening and prevention of obesity in the elderly appears to be a major public health issue, and remains a priority target for action.
