The aim of the study was to investigate the relationship between gastritis and leptin and ghrelin in elderly patients. Patients older than 75 years undergoing an endoscopy were included. We reported data on nutritional status and Helicobacter pylori infection diagnosis (serology, [sup.13]C-urea breath test, culture, histology, and polymerase chain reaction on gastric biopsies). Gastric messenger RNA expression of leptin and ghrelin were quantified by real-time polymerase chain reaction. Sixty-two patients were included (84.7 [+ or -] 5.2 years). H. pylori infection was associated with decreased gastric expression of leptin (p = .021), ghrelin (p = .002), and plasma ghrelin levels (p = .018). Atrophy was associated with decreased gastric leptin (p = .007) and ghrelin (p = .02). H. pylori infection correlated negatively with patient energy intake (r = -0.36; p .001) and body mass index (r = -0.34; p = .018). The negative association between ghrelin and H. pylori infection may be related to a higher prevalence of atrophy and raises the possibility that H. pylori may be contributing to undemutrition in some older people.

Objective. To assess the effects of delirium on the institutionalization rate, taking into account geriatric syndromes and nutritional status. Methods. This population-based study took place in an acute care unit and included participants older than 75 years, arriving from home and later discharged. Confusion Assessment Method (CAM) symptoms were recorded by the nurses within 24 hours after admission and every 3 days. Delirium was defined using the CAM algorithm, and subsyndromal delirium responded to symptoms not fulfilling the CAM algorithm. These delirium categories were either present at admission (prevalent) of occurred during the hospital stay (incident). Participants were classified as having a low dietary intake when energy intake was at any time lower than 600 kcal/d. Age, sex, known cognitive impairment, weight, functional dependency, and laboratory testing as well as diagnoses were also recorded. Step-by-step backward logistic regression was used to identify predictors of institutionalization. Results. Among 427 patients, 310 (72.6%) were discharged and were compared with 117 (27.4%) participants admitted to an institution. Female sex (odds ratio [OR]: OR 2.15, 95% confidence interval [CI]: CI 1.22-3.78), prevalent delirium (OR 3.19, 95% CI 1.33-7.64), subsyndromal delirium (OR 2.72, 95% CI 1.48-5.01), incident subsyndromal delirium (OR 4.27, 95% CI 2.17-8.39), low dietary intake (OR 2.50, 95% CI 1.35-4.63), and a fall (OR 2.16, 95% CI 1.22-3.84) or a diagnosis of stroke (OR 2.03, 95% CI 1.04-3.94) were independent predictors of institutionalization. Conclusions. Symptoms of delirium and severe nutritional impairment led patients to geriatric institutions. Therefore, these institutions need to implement policies that address both of these issues.

Coronary heart disease is a common and serious condition in patients aged over 80 years. The presenting clinical symptoms are all the more atypical and the prognosis poorer when it occurs in patients with multiple comorbid diseases. The presence of comorbidities dictates the need for a standardized geriatric assessment to screen for the existence of underlying frailty. The available scientific data were obtained during studies that included few subjects aged over 80 years. These recommendations are therefore mainly extrapolated from results obtained in younger populations. The pharmacological management and revascularization strategy for coronary heart disease in octogenarians is basically the same as in younger subjects. Epidemiological studies all concur that available therapies are underutilized despite the fact that this population has a high cardiovascular risk. Specific precautions for use must be respected because of the comorbidities and age-related changes in pharmacokinetics or pharmacodynamics. Generally, the therapeutic strategy in coronary heart disease is based not on the patient's real age, but rather on an individual analysis taking into account the severity of the coronary disease, comorbidities, the risk of drug misadventures, patient life expectancy and quality of life.

Beta blockers remain underused in elderly patients with heart failure. Age is not a contraindication to beta blockers. The SENIORS study confirmed that beta blockers are both efficacious and well tolerated in elderly people with heart failure, regardless of their ejection fraction. Because adverse effects may be both more frequent and more serious in the elderly, prescription protocols must be strictly applied. Patients in stable NYHA stages II or III may begin beta blocker treatment, at least 1 month after any decompensation. The initial dose must be as low as possible (1.25 mg/d for bisoprolol and nebivolol). Doses must be increased very progressively and stages longer than 15 days may be necessary. The objective is to reach the target dose (10mg/d for bisoprolol and nebivolol), given the dose-response effect that exists for beta blockers in elderly people with heart failure. In the case of low blood pressure, antihypertensive treatments must be reduced or stopped (for example, nitrate derivatives or calcium channel blockers). A reduction in the dosage of any diuretic dosage and finally of the beta blocker may follow, if necessary. Should bradycardia occur, any anti-bradycardia treatments (such as digoxin or amiodarone) must be reduced or stopped before the beta blocker dosage is reduced.

Introduction: Arteriovenous fistula is a curable cause of high output congestive heart failure., Case: An 89-year-old woman was hospitalized for acute heart failure. The presence of a continuous murmur in the right carotid artery suggested an arteriovenous fistula. Arteriography showed a dural fistula of the right lateral sinus and confirmed the diagnostic hypothesis. Embolization was ruled out because of the patient's clinical condition, but medical treatment produced a satisfactory outcome., Discussion: Clinical diagnosis of an arteriovenous fistula is based on the characteristic murmur. We report the first case of a dural arteriovenous fistula manifested by congestive heart failure in an elderly patient.
