Which parameters differ in very old patients with chronic atrial fibrillation treated by anticoagulant or aspirin? Antithrombotic treatment of atrial fibrillation in the elderly.

The objective was to determine the main parameters taken into account for the decision of antithrombotic treatment of atrial fibrillation (AF) by vitamin K antagonist or aspirin. This was a prospective clinical study of four clinical services of geriatric medicine. Two hundred and nine inpatients, 84.7 +/- 7 years (women 60.8%), with chronic AF were included. The patients were distributed into two groups (anticoagulant or aspirin) according to medical decision. All the decision criteria for treatment were recorded: cardiopathy, conditions of life, clinical examination (nutrition and autonomy, mini-mental state examination (MMSE), walking evaluation, comorbidity), subjective evaluation of risk of falls and glomerular filtration rate. The thromboembolic risk and the bleeding risk, evaluated subjectively for each patient, were compared with two scores of thrombo-embolic risk and bleeding risk. The evolution of the patients was recorded after 3 months. Student's t-test and chi-squared tests were used for statistical analysis. One hundred and two patients (48.8%) received anticoagulant and 107 patients received aspirin. Patients in the aspirin group were significantly older (86.5 +/- 6.5 vs. 82.9 +/- 7.1 years), with more frequent social isolation, higher systolic blood pressure, and had more important subjective bleeding risk and risk of falls. Patients in the anticoagulant group had significantly more valvulopathies and a more important subjective thromboembolic risk. Thrombo-phlebitis antecedents, dementia, denutrition and walking alterations were only slightly more frequent in patients in the aspirin group. Physicians underestimated thromboembolic risk (one-third of patients) and they overestimated bleeding risk (half of the patients). After 3 months, the two groups did not significantly differ for death, bleeding or ischaemic events. In common practice, the decision of antithrombotic treatment for AF should take into account not only cardiovascular but also geriatric criteria.

Risk factors and management of diabetes in elderly French patients.

AIMS: The aim of this study was to assess the characteristics of elderly diabetic patients, evaluate the relationship between glycaemic control and diabetes complications, and compare the day-to-day management of such patients with the published recommendations. METHODS: The study included 238 elderly diabetic patients, for whom data for the past six months' medical history, clinical examination (including ocular fundus) and standard biological tests were collected. RESULTS: The patients' mean age was 82.2+/-7.2, HbA(1c) value was > or =8.5% in 24% of patients and the mean number of cardiovascular risk factors (CVRF) was 4.1+/-0.7 per patient. Dementia or cognitive impairment was present in 68% of patients. Estimated glomerular filtration rate was 30 mL/min or lesser than 16%. Retinopathy was present in 37% of patients, and 64% had a history of infection in the past six months; more than 50% of patients took insulin. The prevalence of retinopathy, cognitive dysfunction and infections were significantly less frequent in patients with HbA(1c) < or =6.5%. There was a positive correlation between the number of CVRF and the number of cardiovascular anomalies (r=0.19, P<0.001). With the exception of HbA(1c), standard paraclinical tests were performed in less than 50% of patients. There was positive agreement between day-to-day HbA(1c) and HbA(1c) target values in 36% of patients. CONCLUSION: Complications and/or associated diseases were more frequent in this cohort of elderly diabetic patients compared with those in studies not based on clinical examinations. Our results highlight the inadequate management, given the frequent discrepancy between day-to-day HbA(1c) and HbA(1c) targets, of such patients.

Mylohyoid motor-evoked potentials relate to swallowing function after chronic stroke dysphagia.

This work aimed to study mylohyoid motor-evoked potentials (MHMEPs) and examined if it is related to chronic stroke dysphagia. Conduction time (CT) and amplitudes of the right and left MHMEPs in response to focal cortical magnetic stimulations over affected and unaffected hemispheres were recorded in 16 stroke patients with aspiration (n = 9) or residue (n = 7) and compared with eight control patients. In control group, MHMEPs were present on ipsilateral and contralateral sides after stimulation of both hemispheres and permitted to determine a dominant hemisphere. In stroke patients, after stimulation of the affected hemisphere, ipsilateral MEPs had a longer CT and lower amplitudes in patients with aspiration compared with patients with residue or control patients (P < 0.05). Contralateral CT was not different between the three groups, but amplitudes were lower in patients with residue and aspiration than in control patients (P < 0.01). In the unaffected hemisphere, MHMEPs were present, and not different between the three groups for the ipsilateral side and amplitudes were decreased in contralateral side in patients with residue. In conclusion, MHMEP alterations of the affected hemisphere related to chronic stroke dysphagia severity and were closed to normal in the unaffected hemisphere.
