Conclusions: Influenza A and B were equally prevalent. Patients had globally similar characteristics. Patients with influenza A virus infection were more often hospital-admitted and oseltamivir treated; however in-hospital and medium-term mortality rates were not significantly different. Influenza B virus infections can be just as severe as influenza A virus infections.

Abstract Influenza A and B outbreaks occur each year with different activity and molecular patterns. To date, knowledge of seasonal epidemiology remains a prerequisite not only to put in place the most effective immunization strategy against influenza but also to identify population groups at higher risk of developing serious complications. A retrospective analysis of influenza surveillance data from 2010 to 2018 aimed to explore the epidemiology of influenza in Sicily, at the primary care and hospital level. Overall, 6,740 patients with acute respiratory infection were tested, of which 3,032 (45.0%) were positive...

Publication date: Available online 19 September 2019Source: Obesity Research &Clinical PracticeAuthor(s): Sandra Angélica Rojas-Osornio, Teresita Rocío Cruz-Hernández, Maria Elisa Drago-Serrano, Rafael Campos-RodríguezAbstractObesity is a health concern that is recognized as a critical factor for vulnerability to influenza A/pdmH1N1 virus infection, with epidemiological and clinical impacts. In humans, obesity induces disturbances in inflammatory and immune responses to the influenza virus and in some cases, this leads to severe complications, with fatal outcomes. Obesity impairs immunity by...

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.

Listen to critics of the Wheat Belly lifestyle and you’d think that, by banishing all things wheat and grains from your life, you will be excommunicated from your church, tossed out of your club, ostracized by friends and family, and suffer dire health consequences like heart disease and colon cancer. After all, they say that you are eliminating an entire food group and will be crippled by lack of fiber and nutrients. Worse, our focus on increasing our intake of fats and oils will get you a heart attack, three stents, or bypass surgery and you’ll be obliged to take Lipitor and Repatha for a lifetime. First of a...

In conclusion, there is solid evidence that obesity deregulates cellular mechanisms related to nutrient sensing. Altered Intercellular Communication It is accepted that aging impacts the organism at the cellular level, but also decreases the capacity of cells of an organism to interact. During aging, there is a decreased communication at the neuronal, neuroendocrine, and endocrine levels. Two of the most compelling examples of impaired communication are inflammaging and immunosenescence. The inflammaging phenotype results in elevated cytokines. These cytokines can accelerate and propagate the aging process. T...

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...

With the rising prevalence of obesity has come an increasing awareness of its impact on communicable disease. As a consequence of the 2009 H1N1 influenza A virus pandemic, obesity was identified for the first time as a risk factor for increased disease severity and mortality in infected individuals. Over-nutrition that results in obesity causes a chronic state of meta-inflammation with systemic implications for immunity. Obese hosts exhibit delayed and blunted antiviral responses to influenza virus infection, and they experience poor recovery from the disease. Furthermore, the efficacy of antivirals and vaccines is reduced...

Conclusion and Perspectives Being exquisitely regulated by “writers,” “erasers,” and “readers,” additional repelled proteins or miRNAs, m6A modification relates to nearly any step of mRNA metabolism, as well as ncRNA processing and circRNA translation. There is compelling evidence suggesting that m6A modification is especially critical in a variety of pathologic and physiologic immune responses including T cell homeostasis and differentiation, inflammation, and type I interferon production. Further results have indicated that aberrancies of interferon and Th17 frequencies in systemic lu...
