Trend of mortality from ischemic heart disease and influenza vaccination in older adults in São Paulo

Abstract The aim of the present study was to analyze the mortality trend due to ischemic heart disease (IHD) among older adults, identify changes in the trend and determine the correlation with influenza vaccine coverage (2000 to 2012) in the state of S ão Paulo between 1980 and 2012. An ecological time series study was conducted involving secondary data from Brazilian information systems. Linear and polynomial regression models as well as joinpoint regression were used to estimate the trends. Pearson ’ s correlation coefficient was used to evaluate the correlation between age-standardized mortality coefficients and vaccine coverage. A decreasing tendency in mortality due to IHD occurred in both sexes, higher mortality rates were found for males and greater reductions were found in the period after the vaccination campaigns. However, no statistically significant changes occurred in the year coinciding with or near the onset of the campaigns. In the overall sample, no evidence of a linear correlation was found between the mortality coefficients and vaccination coverage. Other factors directly associated with morbidity and mortality due to ischemic heart disease may have influenced the trend.Resumo O objetivo deste artigo é analisar a tendência dos coeficientes de mortalidade por doenças isquêmicas do coração (DIC) nos idosos no estado de São Paulo, entre 1980 e 2012, identificar mudanças na tendência e ve...

Grams, Josef Coresh, Alex Chang, Kunihiro MatsushitaRationale &ObjectiveInfluenza vaccination is recommended for all adults but particularly for older adults and those with high-risk conditions. Reduced kidney function is an important high-risk condition, but the effectiveness of influenza vaccination across kidney function is uncharacterized. We assessed the effectiveness of influenza vaccination among older adults with and without reduced kidney function.Study DesignObserv...

In this study, we hypothesized that moderately and chronically reducing ACh could attenuate the deleterious effects of aging on NMJs and skeletal muscles. To test this hypothesis, we analyzed NMJs and muscle fibers from heterozygous transgenic mice with reduced expression of the vesicular ACh transporter (VAChT), VKDHet mice, which present with approximately 30% less synaptic ACh compared to control mice. Because ACh is constitutively decreased in VKDHet, we first analyzed developing NMJs and muscle fibers. We found no obvious morphological or molecular differences between NMJs and muscle fibers of VKDHet and contro...

James Peyer, formerly of Apollo Ventures and now at the larger Kronos BioVentures, has a range of interesting views on the new and growing longevity biotechnology industry. Apollo Ventures was one of the earlier longevity-focused funds to emerge from the comparatively small community of scientists, patient advocates, and investors enthusiastic to accelerate progress towards the treatment of aging as a medical condition. The presentation here was given earlier this year at the Ending Age-Related Diseases conference organized by the Life Extension Advocacy Foundation. In the matter of creating new medical therapies, t...

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...

In this study we show, for the first time, significant alterations in cholesterol efflux capacity in adolescents throughout the range of BMI, a relationship between six circulating adipocyte-derived EVs microRNAs targeting ABCA1 and cholesterol efflux capacity, and in vitro alterations of cholesterol efflux in macrophages exposed to visceral adipose tissue adipocyte-derived EVs acquired from human subjects. These results suggest that adipocyte-derived EVs, and their microRNA content, may play a critical role in the early pathological development of ASCVD. Commentary on the Developing UK Government Position on Hea...

Increasing evidence suggests that influenza vaccination can reduce coronary heart disease (CHD) outcomes. CHD and influenza cause a significant burden among Australian adults aged 50 –64, however, vaccine coverage remains suboptimal. The National Immunisation Program (NIP) funds vaccinations in this group only for those at high risk. The aim of this study was to determine whether expanding the NIP to all adults aged 50–64 to prevent acute myocardial infarction (AMI) and resp iratory hospitalisations will be cost beneficial.

In this study, we found that cofilin competes with tau for direct microtubule binding in vitro, in cells, and in vivo, which inhibits tau-induced microtubule assembly. Genetic reduction of cofilin mitigates tauopathy and synaptic defects in Tau-P301S mice and movement deficits in tau transgenic C. elegans. The pathogenic effects of cofilin are selectively mediated by activated cofilin, as active but not inactive cofilin selectively interacts with tubulin, destabilizes microtubules, and promotes tauopathy. These results therefore indicate that activated cofilin plays an essential intermediary role in neurotoxic signaling th...

In conclusion, the mouse pharyngeal colonization model is an affordable and accessible experimental system that allows a broader group of research groups to test the importance of their findings in an in vivo model. There is a great deal of overlap between the bacterial and immune factors found to be important in human and murine pharyngeal colonization. Although MHC-II humanized mice could prove useful in answering certain questions, the use of inbred mouse lines appears to be sufficient for evaluation of most questions, both related to bacterial factors and the host immune response. However, when promising treatments or ...

In this study, herpes virus serological status and T cell, B cell, NK cell and monocyte populations were investigated in 251 ME/CFS patients, including 54 who were severely affected, and compared with those from 107 healthy participants and with 46 patients with Multiple Sclerosis. There were no differences in seroprevalence for six human herpes viruses between ME/CFS and healthy controls, although seroprevalence for the Epstein-Barr virus was higher in multiple sclerosis patients. Contrary to previous reports, no significant differences were observed in NK cell numbers, subtype proportions or in vitro responsiveness betwe...

This study is complemented by another report that found that hRSV infection induces significant expression of three miRNAs, namely hsa-miR-4448, hsa-miR-30a-5p, and hsa-miR-4634 in human DCs (104). Interestingly, this latter study also performed comparative analyses of miRNA profiles between DCs infected with hRSV and a related virus, namely the human metapneumovirus, and found that both viruses induced the expression of elevated levels of hsa-miR-4634. Elucidating the contribution of these miRNAs in DCs in response to hRSV remains to be determined. Dendritic Cell Phenotype and Migration Upon hRSV Infection in vivo Altho...
