Association between the polymorphism of CCR5 and Alzheimer's disease: results of a study performed on male and female patients from Northern Italy.

2007

Alzheimer's disease (AD) is the most common cause of dementia in Western society. The prevalence of AD is greater in women than in men, largely due to longevity and survival differences favoring women. However, some studies suggest that incidence rates may really be increased in women. One possible factor influencing AD incidence in women is the loss of ovarian estrogens production after menopause, which might be involved in AD pathogenesis. Estrogens seem to influence some neuronal functions. Many of these actions appear beneficial (i.e., neuroprotective action against a variety of insults, as oxidative stress, and reduction of beta-amyloid plaques formation). Furthermore, several studies …

Induction of RAGE Shedding by Activation of G Protein-Coupled Receptors

2011

The multiligand Receptor for Advanced Glycation End products (RAGE) is involved in various pathophysiological processes, including diabetic inflammatory conditions and Alzheimers disease. Full-length RAGE, a cell surface-located type I membrane protein, can proteolytically be converted by metalloproteinases ADAM10 and MMP9 into a soluble RAGE form. Moreover, administration of recombinant soluble RAGE suppresses activation of cell surface-located RAGE by trapping RAGE ligands. Therefore stimulation of RAGE shedding might have a therapeutic value regarding inflammatory diseases. We aimed to investigate whether RAGE shedding is inducible via ligand-induced activation of G protein-coupled recep…

Prevalence, Incidence, and Progression of Cognitive Impairment, No Dementia Among Rural-Dwelling Chinese Older Adults

2022

Background: Few studies have examined occurrence and progression of cognitive impairment, no dementia (CIND) in rural China. Objective: To determine the prevalence and incidence of CIND in rural-dwelling Chinese older adults, and to examine risk and protective factors associated with progression to CIND and dementia. Methods: This population-based study included 2,781 dementia-free participants (age≥65 years) who were examined at baseline (2014) and followed in 2018. Demographic, epidemiological, clinical, and neuropsychological data were collected following a structured questionnaire. We defined CIND according to subjective cognitive complaints and the age- and education-specific Mini-Ment…

Sensory functions and Alzheimer's disease: a multi-disciplinary approach

2015

Relations between sensory functions and Alzheimer's disease are still under-explored. To understand them better, the Fondation Médéric Alzheimer has brought together a multi-disciplinary expert group. Aristote's five senses must be enhanced by today's knowledge of proprioception, motor cognition and pain perception. When cognition breaks down, the person with dementia perceives the world around her with her sensory experience, yet is unable to integrate all this information to understand the context. The treatment of multiple sensory inputs by the brain is closely linked to cognitive processes. Sensory deficits reduce considerably the autonomy of people with dementia in their daily life and…

"a priori" Dietary Patterns and Cognitive Function in the SUN Project

2019

<b><i>Objectives:</i></b> To study and compare associations of 5 dietary patterns – Mediterranean dietary pattern (MDP), Dietary Approaches to Stop Hypertension (DASH), Mediterranean-DASH Intervention for Neurodegenerative delay (MIND), Alternative Healthy Eating Index (AHEI-2010), and a pro-vegetarian diet (PVD) – with cognitive function. <b><i>Patients and Methods:</i></b> A subgroup of 806 participants from the “Seguimiento Universidad de Navarra”(SUN) cohort of university graduates, >55 years old, was interviewed with the validated Spanish Telephone Interview for Cognitive Status (STICS-m) at baseline and after 2 and 6 years. For …

Brain and kidney, victims of atrial microembolism in elderly hospitalized patients? Data from the REPOSI study

2015

Abstract Background It is well known that atrial fibrillation (AF) and chronic kidney disease (CKD) are associated with a higher risk of stroke, and new evidence links AF to cognitive impairment, independently from an overt stroke (CI). Our aim was to investigate, assuming an underlying role of atrial microembolism, the impact of CI and CKD in elderly hospitalized patients with AF. Methods We retrospectively analyzed the data collected on elderly patients in 66 Italian hospitals, in the frame of the REPOSI project. We analyzed the clinical characteristics of patients with AF and different degrees of CI. Multivariate logistic analysis was used to explore the relationship between variables an…

A SIMPLE TECHINIQUE TO IMPROVE RESIDUAL SKIN PLASTICITY FOR SCROTAL RECONSTRUCTION IN FOURNIER'S GANGRENE

2012

A 50 years-old man developed 24 hours after hemorrhoidectomy a severe Fournier's gangrene of the scrotum necessitating surgical exeresis of more than 2/3 of scrotal skin followed by hyperbaric oxygen therapy. After the resolution of the septic phase, scrotum reconstruction was obtained by tissue expansion to avoid more invasive advanced reconstructive techniques. The procedure consisted of an enzymatic and mechanical debridement and progressive skin expansion by package of gauzes of increasing volume covered with a collagenasecloramphenicol ointment (Iruxol®- Smith and Nephew, Italy), then closing the wound edges by temporary stitches to put under tension the skin. The reestablishment of th…

Sleep Alterations in Non-demented Older Individuals: The Role of Cortisol

2017

Background: Sleep alterations can impair quality of life and contribute to disease progression but they, and their features and contributing factors, are rarely analysed in institutionalised older individuals. In this study, we investigated sleep alterations, the factors involved, and the role of cortisol in sleep-related problems in institutionalised individuals. Methods: We conducted a descriptive cross-sectional study in participants living in nursing homes in Valencia (Spain); sleep alterations were determined based on two validated tools: the Athens insomnia scale and Oviedo sleep questionnaire. Plasma cortisol was measured in the morning and determined by high performance liquid chrom…

Bidirectional relationship between caregiver burden and neuropsychiatric symptoms in patients with Alzheimer's disease: A narrative review

2019

Objective: The aim of this review is to make a state of the art of the potential influence of neuropsychiatric symptoms (NPs) on caregiver stress and vice versa. Methods: We searched PubMed and Google Scholar for potential eligible articles. Results: Patients with Alzheimer's disease (AD) usually need high levels of care in all activities of daily living, most of them provided by family members, friends, or informal caregivers. Caregivers have to cope with both age-related conditions and dementia-related factors. Therefore, caregiving in dementia is more difficult and stressful than caregiving for older adults, affected by other conditions. Neuropsychiatric symptoms, such as anxiety, agitat…
