Role of sex and age in fatal outcomes of COVID-19: women and older centenarians are more resilient.

2023

In the present paper, we have analysed the role of age and sex in the fatal outcome of COVID-19, as there are conflicting results in the literature. As such, we have answered three controversial questions regarding this aspect of the COVID-19 pandemic: (1) Have women been more resilient than men? (2) Did centenarians die less than the remaining older people? (3) Were older centenarians more resistant to SARS-CoV-2 than younger centenarians? The literature review demonstrated that: (1) it is women who are more resilient, in agreement with data showing that women live longer than men even during severe famines and epidemics; however, there are conflicting data regarding centenarian men; (2) c…

Hereditary cerebral hemorrhage with amyloidosis associated with the E693K mutation of APP

2010

Objective To report the clinical, genetic, neuroimaging, and neuropathologic studies of patients with the hereditary cerebral hemorrhage with amyloidosis linked to the APP E693K mutation. Design Case series. Clinical details and laboratory results were collected by direct evaluation and previous medical records. DNA analysis was carried out in several affected subjects and healthy individuals. Neuropathologic examination was performed in 2 subjects. Setting Southern Lombardy, Italy. Patients Individuals with and without amyloidosis in 4 unrelated Italian families (N = 37). Main Outcome Measure Genotype-phenotype relationship. Results The affected individuals presented with recurrent headach…

Amyotrophic Lateral Sclerosis, a Multisystem Pathology: Insights into the Role of TNFα

2017

Amyotrophic lateral sclerosis (ALS) is considered a multifactorial, multisystem disease in which inflammation and the immune system play important roles in development and progression. The pleiotropic cytokine TNFαis one of the major players governing the inflammation in the central nervous system and peripheral districts such as the neuromuscular and immune system. Changes in TNFαlevels are reported in blood, cerebrospinal fluid, and nerve tissues of ALS patients and animal models. However, whether they play a detrimental or protective role on the disease progression is still not clear. Our group and others have recently reported opposite involvements of TNFR1 and TNFR2 in motor neuron dea…

Neocortical Variation of Abeta Load in Fully Expressed, Pure Alzheimer's Disease

2010

The relationship between amyloid-beta (A beta) deposition and tau-related neurofibrillary changes is a key issue in the pathogenesis of Alzheimer's disease (AD). The aim of this study was to investigate the extent and cortical distribution of A beta and tau pathology, their mutual links and their correlation with the duration of the disease in thirty-nine patients with fully expressed AD. By tau immunohistochemistry, we identified different patterns of distribution of neurofibrillary changes that were ascribed to Braak stage V and VI. The disease duration was longer in patients at Braak stage VI than in those at V. Morphometric analysis carried out in several neocortical areas demonstrated …
