Objectives-Cognitive impairment has been reported in middle aged patients with end stage heart failure. This cross sectional study assessed the prevalence and determinants of cognitive dysfunction in older patients with mild to moderate heart failure. Methods-57 consecutive patients (mean age 76.7 years) with chronic heart failure underwent physical examination, blood chemistry, urinalysis, chest radiography ECG, Doppler echocardiography, and the mini mental state examination (MMSE), mental deterioration battery, depression scale of the Center for Epidemiological Studies (CES-D), Katz activities of daily living, and instrumental activities of daily living 24 hours before hospital discharge. Results-MMSE scores <24 were found in 53% of participants. The MMSE score was associated with left ventricular ejection fraction according to a non-linear correlation, so that cognitive performance was significantly lower in subjects with left ventricular ejection fraction <30%. The same pattern of correlation was evidenced between left ventricular ejection fraction and both the attention sub-item of MMSE and the Raven test score. In a multivariate linear regression model, after adjusting for age, sex, and a series of clinical data and objective tests, both age ( =−0.30; P=0.038) and the natural log of left ventricular ejection fraction ( =0.58; P=0.001) were associated with the MMSE score. Conclusion-Cognitive impairment in older patients with chronic heart failure is common, and independently associated with lower left ventricular ejection fraction. Given the overwhelming incidence and prevalence of heart failure in older populations, early detection of cognitive impairment in these subjects with prompt, intensive treatment of left ventricular systolic dysfunction may prevent or delay a remarkable proportion of dementia in advanced age.
Systolic hypotension is selectively associated with cognitive impairment in older patients with heart failure. As early treatment of cardiac low-output states can reverse cognitive dysfunction, the routine management of heart failure should include systematic assessment of cognitive performance.
Endoscopic sphincterotomy for choledocholithiasis is found to be safe at long-term follow-up. A dilated bile duct (> or = 22 mm) is a marker for patients at increased risk of recurrence of symptoms and/or choledocholithiasis.
Nutrition variables are a cardinal component of comprehensive geriatric assessment. Our results suggest that BMI, a simple anthropometric measure of nutritional status, is an important predictor of mortality among older people living in the community. Even when controlling for clinical and functional variables, a low BMI remained a significant and independent predictor of shortened survival.
The discovery of Helicobacter pylori infection in the stomach could be considered as one of the most important events of modern gastroenterology. Understanding of the natural history of many disorders of the upper gastrointestinal tract, including chronic gastritis, peptic ulcer disease, gastric cancer and MALT lymphoma, was altered by this discovery. Interestingly, epidemiological studies have also revealed a correlation between H. pylori infection and some diseases localized outside the stomach, especially those characterized by persistent and low-grade systemic inflammation. Of note, H. pylori has an important role in iron deficiency anaemia, idiopathic thrombocytopenic purpura and vitamin B12 deficiency. Moreover, the association of this bacterial pathogen with many other diseases, including hepatobiliary, pancreatic, cardiovascular and neurodegenerative disorders is currently under investigation. In this Review, we summarize the results of the most important studies performed to date surrounding the association of H. pylori infection with extragastric diseases, as well as the strength of the evidence. We also provide information concerning bacterial-host interactions and the mechanisms implicated in the pathogenesis of each of these extragastric diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
