The aim of this pilot study was to analyze spontaneous electroencephalography (EEG) activity in Alzheimer's disease (AD) by means of Cross-Sample Entropy (Cross-SampEn) and two local measures derived from graph theory: clustering coefficient (CC) and characteristic path length (PL). Five minutes of EEG activity were recorded from 37 patients with dementia due to AD and 29 elderly controls. Our results showed that Cross-SampEn values were lower in the AD group than in the control one for all the interactions among EEG channels...

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the only treatment with a curative potential for myelodysplastic syndrome (MDS) patients. Allo-HSCT has substantial risks, particularly in the elderly, and its role for older MDS patients has yet to be defined. METHODS: We analyzed 88 MDS patients aged ≥ 60 years with allo-HSCT after reduced intensity conditioning regimens over the last decade. The study cohort had high risk features; 47 of 88 (53...

Age is one of the main risk factor for the presence of obstructive sleep apnea (OSA). This syndrome is associated with hypertension, cardiovascular disease, cognitive impairment and metabolic abnormalities, such as type 2 diabetes. Continuous positive airway pressure (CPAP) represents the gold standard therapy, but its benefit is still to be determined in very elderly. We report the blood pressure and metabolic changes in a very elderly obese with severe OSA after 3-month CPAP therapy. We have evaluated a very elderly obese male affected by severe symptomatic OSA, poor controlled nocturnal hypertension and insulin resistance...

Acute diarrhea leads to a substantial disease burden among the elderly worldwide. However, in the context of increasingly aging trend in China, the prevalence of etiological agents among elderly diarrheal patients was undetermined. This study aimed to explore the major enteropathogens of acute diarrhea among outpatients older than 65 years in China, and also the epidemiological features of the pathogens. Demographic and clinical data for acute diarrhea among outpatients older than 65 years were collected from 213 participating hospitals from 2009 to 2014...

BACKGROUND: Low bone mineral density (BMD) is a known independent predictor of mortality in the general elderly population. However, studies in patients with end-stage renal disease (ESRD) are limited. The present study evaluated mortality during long-term follow-up in a population of patients having dialysis for ESRD, in whom BMD was also measured. METHODS: Fifty-eight patients with ESRD were recruited consecutively from a dialysis clinic and followed prospectively for 6 years...

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare condition in the elderly and can appear as a first presentation of various types of rheumatic and malignant diseases. We presented a 62-year-old man with the diagnosis of RS3PE based on the clinical sign and laboratory data. Because of the possibility of associated malignancies in RS3PE, FDG PET/CT was performed to exclude occult tumors. The images showed multiple, symmetrically, diffusely increased F-FDG uptake in the soft tissue around joints and bones in the shoulders, hips, knees, and ankles...

Large cohort studies suggest that high convective volumes associated with online hemodiafiltration may reduce the risk of mortality/morbidity compared to optimal high-flux hemodialysis. By contrast, intradialytic tolerance is not well studied. The aim of the FRENCHIE (French Convective versus Hemodialysis in Elderly) study was to compare high-flux hemodialysis and online hemodiafiltration in terms of intradialytic tolerance. In this prospective, open-label randomized controlled trial, 381 elderly chronic hemodialysis patients (over age 65) were randomly assigned in a one-to-one ratio to either high-flux hemodialysis or online hemodiafiltration...

Bullous pemphigoid (BP) is a chronic debilitating autoimmune blistering disease that frequently occurs in the elderly population. Previous studies have suggested a high morbidity and mortality associated with BP. However, relatively few studies have investigated prognostic factors of BP mortality, and they showed considerably various results. This meta-analysis aimed to quantitatively assess the association between several potential prognostic factors and risk of mortality in bullous pemphigoid. A comprehensive search was performed using Pubmed, Embase, and Cochrane Library...

A side effect of increased life expectancy is a surge in sequelae of diseases and injuries, which in turn increase the duration of life with disability among the elderly. The aim of this study was to ascertain the physical activity and nutritional parameters that better predict cardiovascular risk in a cohort of older women. A cross-sectional study was designed including 65 women able to independently perform basic activities of daily life. Data collection included anthropometric measurement, blood pressure measurement, blood analytics, objectively measurement of physical activity, and dietary assessment...

Retinal degenerative diseases, which include age-related macular degeneration, retinitis pigmentosa, diabetic retinopathy and glaucoma, mostly affect the elderly population, and are the most common cause of decreased quality of vision or even blindness. So far, there is no satisfactory treatment protocol to prevent, stop or cure these disorders. A great hope and promise for patients suffering from retinal diseases is represented by stem cell-based therapy which could replace diseased or missing retinal cells, and support regeneration...

Alzheimer's disease (AD) is characterized by two hallmark molecular pathologies: amyloid aβ1-42, and Tau neurofibrillary tangles. To date, studies of functional connectivity MRI (fcMRI) in preclinical AD have relied on associations with in-vivo measures of amyloid pathology. With the recent advent of in-vivo Tau-PET tracers it is now possible to extend investigations on fcMRI in a sample of cognitively normal elderly humans to regional measures of Tau. We modeled fcMRI measures across four major cortical association networks (Default Mode (DMN), Salience, Dorsal Attention (DAN), and Frontoparietal Control (FPCN)) as a function of global cortical amyloid (PiB-PET) and regional Tau (AV1451-PET) in entorhinal, inferior temporal (IT), and inferior parietal (IP) cortex...

Whether to initiate oral anticoagulant therapy in advanced chronic kidney disease patients with atrial fibrillation remains debatable. Although randomized trial data are lacking, observational studies yield controversial results. Keskar and colleagues analyzed data from a Canadian health care system and found that in elderly chronic kidney disease patients with atrial fibrillation, oral anticoagulant therapy did not prevent ischemic strokes, induced hemorrhages, but prolonged life. These paradoxical findings emphasize the dire need for an adequately powered randomized trial...

BACKGROUND: Effective interventions are needed to improve brain function in mild cognitive impairment (MCI), an early stage of Alzheimer's disease (AD). The posterior cingulate cortex (PCC)/precuneus is a hub of the default mode network (DMN) and is preferentially vulnerable to disruption of functional connectivity in MCI and AD. OBJECTIVE: We investigated whether 12 weeks of aerobic exercise could enhance functional connectivity of the PCC/precuneus in MCI and healthy elders...
