Relationship Between Body Mass Index, ApoE4 Status, and PET-Based Amyloid and Neurodegeneration Markers in Amyloid-Positive Subjects with Normal Cogn…
2018
Body weight loss in late-life is known to occur at a very early stage of Alzheimer's disease (AD). Apolipoprotein E4 (ApoE4) represents a major genetic risk factor for AD and is linked to an increased cortical amyloid-β (Aβ) accumulation. Since the relationship between body weight, ApoE4, and AD pathology is poorly investigated, we aimed to evaluate whether ApoE4 allelic status modifies the association of body mass index (BMI) with markers of AD pathology. A total of 368 Aβ-positive cognitively healthy or mild cognitive impaired subjects had undergone [18F]-AV45-PET, [18F]-FDG-PET, and T1w-MRI examinations. Composite cortical [18F]-AV45 uptake and [18F]-FDG uptake in posterior cingulate cor…

Benign nocturnal alternating hemiplegia of childhood
2018
Objective: To describe the clinical spectrum of benign nocturnal alternating hemiplegia of childhood (BNAHC) including long-term follow-up data of previously published cases and to propose an underlying genetic cause of this disorder. Methods: We studied the medical data of two novel patients, reviewed the literature on BNAHC, and gathered information of the most recent follow-up of published cases regarding the course of episodes, further development, attempted drugs, ancillary investigations, and sequelae. Results: All patients, i.e. two novel cases and twelve patients identified in the literature (13 boys, 1 girl, age at onset four months to three years), experienced episodes of hemipleg…
The Socio-Economic Health Deprivation Index and its association with mortality and attitudes towards influenza vaccination among the elderly in Paler…
2019
Abstract Introduction Inequality levels are associated with vaccination coverage among the older and at risk population hypothesizing socio-economic status (SES) as a determinant of health status. The aim of the study was to evaluate the trend of health outcome and socio-health-economic-status deprivation index (IDPA) among elderly people in Palermo city, Italy . Methods The Palermo Unit of 2015 CCM project deal with collection of data useful to validate IDPA using the Italian census data from 2009 to 2015 on overall mortality and cause of death. The preventive outcome used to validate the IDPA index was vaccination coverage from 2009-2010 to 2014-2015 influenza season among Palermo elderly…
Repurposing of the Antiepileptic Drug Levetiracetam to Restrain Neuroendocrine Prostate Cancer and Inhibit Mast Cell Support to Adenocarcinoma
2021
A relevant fraction of castration-resistant prostate cancers (CRPC) evolve into fatal neuroendocrine (NEPC) tumors in resistance to androgen deprivation and/or inhibitors of androgen receptor pathway. Therefore, effective drugs against both CRPC and NEPC are needed. We have previously described a dual role of mast cells (MCs) in prostate cancer, being capable to promote adenocarcinoma but also to restrain NEPC. This finding suggests that a molecule targeting both MCs and NEPC cells could be effective against prostate cancer. Using an in silico drug repurposing approach, here we identify the antiepileptic drug levetiracetam as a potential candidate for this purpose. We found that the protein…
The clinical relevance of adiposity when assessing muscle health in men treated with androgen deprivation for prostate cancer
2019
Background: Androgen deprivation therapy (ADT) for prostate cancer (PCa) may prospectively decrease absolute lean mass (LM) and increase absolute fat mass (FM). Given that estimates of LM by dual‐energy X‐ray absorptiometry may be overestimated in obese people, this study examined the influence of adiposity on muscle health in men treated with ADT for PCa. Methods: This cross‐sectional study examined the influence of adiposity on total and appendicular LM (ALM), muscle cross‐sectional (CSA), and muscle strength in 70 men treated with ADT [mean (standard deviation) age, 71 (6) years] for PCa compared with age‐matched PCa (n = 52) and healthy controls (n = 70). Total body LM, FM and ALM, and …
Brain circuit-gene expression relationships and neuroplasticity of multisensory cortices in blind children.
2017
Sensory deprivation reorganizes neurocircuits in the human brain. The biological basis of such neuroplastic adaptations remains elusive. In this study, we applied two complementary graph theory-based functional connectivity analyses, one to evaluate whole-brain functional connectivity relationships and the second to specifically delineate distributed network connectivity profiles downstream of primary sensory cortices, to investigate neural reorganization in blind children compared with sighted controls. We also examined the relationship between connectivity changes and neuroplasticity-related gene expression profiles in the cerebral cortex. We observed that multisensory integration areas e…
Denosumab for bone health in prostate and breast cancer patients receiving endocrine therapy? A systematic review and a meta-analysis of randomized t…
2019
Highlights • Hormonal receptors positive breast tumor and prostate cancer are managed with endocrine therapies. • Endocrine therapies designed for breast and prostate cancer are often associated to serious adverse skeletal related events, such fractures. • Denosumab is a monoclonal anti-body binding RANKL which acts as inhibitor of osteoclasts activity, thus increasing bone mass. • Denosumab was showed to strongly prevent hormonal therapies-related skeletal issues. • Denosumab administration results safe in bone mass increase and reduction of fractures risk.
Short telomere length is associated with impaired cognitive performance in European ancestry cohorts
2017
AbstractThe association between telomere length (TL) dynamics on cognitive performance over the life-course is not well understood. This study meta-analyses observational and causal associations between TL and six cognitive traits, with stratifications on APOE genotype, in a Mendelian Randomization (MR) framework. Twelve European cohorts (N=17 052; mean age=59.2±8.8 years) provided results for associations between qPCR-measured TL (T/S-ratio scale) and general cognitive function, mini-mental state exam (MMSE), processing speed by digit symbol substitution test (DSST), visuospatial functioning, memory and executive functioning (STROOP). In addition, a genetic risk score (GRS) for TL includin…
Iron-loaded transferrin (Tf) is detrimental whereas iron-free Tf confers protection against brain ischemia by modifying blood Tf saturation and subse…
2018
Despite transferrin being the main circulating carrier of iron in body fluids, and iron overload conditions being known to worsen stroke outcome through reactive oxygen species (ROS)-induced damage, the contribution of blood transferrin saturation (TSAT) to stroke brain damage is unknown. The objective of this study was to obtain evidence on whether TSAT determines the impact of experimental ischemic stroke on brain damage and whether iron-free transferrin (apotransferrin, ATf)-induced reduction of TSAT is neuroprotective. We found that experimental ischemic stroke promoted an early extravasation of circulating iron-loaded transferrin (holotransferrin, HTf) to the ischemic brain parenchyma.…
