Low-dose aspirin as primary prophylaxis for cardiovascular events in systemic lupus erythematosus: A long-term retrospective cohort study

Objectives. Cardiovascular (CV) morbidity and mortality are significantly greater in SLE patients than in the general population. ASA is known to be associated with a decrease in the incidence of CV events in high-risk patients from the general population, but its efficacy as primary prophylaxis in SLE patients has not yet been investigated. Methods. The clinical charts of SLE patients consecutively admitted to a tertiary centre who, at admission, satisfied 1992 ACR and/or 2012 SLICC classification criteria for SLE and had not experienced any CV event, were reviewed. The occurrence of any CV event was recorded at each visit. ASA was prescribed to all patients at first visit. The rate and reasons for ASA discontinuation were also recorded at each visit.Results. One hundred and sixty-seven consecutive SLE patients were enrolled and followed up for a median of 8 years (range 1-14 years). Among them, 146 regularly took the medication (ASA-treated patients) and 21 refused to take or discontinued it (non-ASA-treated patients). Five CV events occurred in the 146 ASA-treated patients (4.2 per 1000 person-years) and four in the 21 non-ASA-treated patients (30 per 1000 person-years; P = 0.0007). The CV event-free rate was higher in ASA-treated than in non-ASA-treated patients (log-rank test χ2 = 15.74; P = 0.0001). No relevant side-effect related to ASA was recorded.Conclusion. Low-dose ASA is a safe treatment and may be beneficial in the primary prophylaxis of CV events in SLE patients. Controlled, prospective studies are needed to provide a better definition of its role in these patients

Prolonged lifespan with enhanced exploratory behavior in mice overexpressing the oxidized nucleoside triphosphatase hMTH1

The contribution that oxidative damage to DNA and/or RNA makes to the aging process remains undefined. In this study, we used the hMTH1-Tg mouse model to investigate how oxidative damage to nucleic acids affects aging. hMTH1-Tg mice express high levels of the hMTH1 hydrolase that degrades 8-oxodGTP and 8-oxoGTP and excludes 8-oxoguanine from both DNA and RNA. Compared to wild-type animals, hMTH1-overexpressing mice have significantly lower steady-state levels of 8-oxoguanine in both nuclear and mitochondrial DNA of several organs, including the brain. hMTH1 overexpression prevents the age-dependent accumulation of DNA 8-oxoguanine that occurs in wild-type mice. These lower levels of oxidized guanines are associated with increased longevity and hMTH1-Tg animals live significantly longer than their wild-type littermates. Neither lipid oxidation nor overall antioxidant status is significantly affected by hMTH1 overexpression. At the cellular level, neurospheres derived from adult hMTH1-Tg neural progenitor cells display increased proliferative capacity and primary fibroblasts from hMTH1-Tg embryos do not undergo overt senescence in vitro. The significantly lower levels of oxidized DNA/RNA in transgenic animals are associated with behavioral changes. These mice show reduced anxiety and enhanced investigation of environmental and social cues. Longevity conferred by overexpression of a single nucleotide hydrolase in hMTH1-Tg animals is an example of lifespan extension associated with healthy aging. It provides a link between aging and oxidative damage to nucleic acids. © 2013 John Wiley & Sons Ltd and the Anatomical Society

Reclamo al CICR- commento all'art.9 TUB

Il reclamo al CICR resta apparentemente immutato come reclamo nazionale avverso i provvedimenti di vigilanza, mentre gli assetti dei poteri di vigilanza bancaria sono da tempo profondamente riconfigurati e incentrati sulla BCE. Nel nuovo sistema di vigilanza è previsto un diverso procediento di reclamo. Si affronta, quindi, principalmente il problema della convivenza dei due rimedi
