The idea of using small RNA fragments (oligonucleotides) for therapeutic purposes dates back to the 1990s, following the landmark discoveries on the mechanisms of gene silencing and RNA-interference (RNA-i). However, the first applications in medicine were hampered by difficulties in chemical stabilization and efficient delivery to target tissues. Recent advances in chemical manipulation of oligonucleotides have, at least partially, bypassed such obstacles. In particular, conjugation with ligands for specific receptors allows the selective uptake of oligonucleotides by critical cells (e...

Most of the cholesterol in plasma is in an esterified form that is generated in potentially cardioprotective high density lipoproteins (HDLs). Cholesteryl ester transfer protein (CETP) mediates bidirectional transfers of cholesteryl esters (CE) and triglycerides (TG) between plasma lipoproteins. Since CE originates in HDLs, and TG enters the plasma as a component of very low density lipoproteins (VLDLs), activity of CETP results in a net mass transfer of CE from HDLs to VLDLs and low density lipoproteins (LDLs), and of TG from VLDLs to LDLs and HDLs...

Background: Statins are used to reduce cardiovascular disease risk. Recent studies suggest that statin use may be associated with an increased influenza risk among influenza vaccinees. We used Medicare data to evaluate associations between statins and risks of influenza-related encounters among vaccinees. Methods: In this retrospective cohort study, we identified Medicare beneficiaries aged >65 years who received high-dose (HD) or standard-dose (SD) influenza vaccines at pharmacies from 2010-11 through 2014-15...

Evidence-based medicine remains the best paradigm for medical practice. However, evidence alone is not decisions; decisions must also consider resources available and the values of people. Evidence shows that most of those treated with blood pressure-lowering, cholesterol-lowering, glucose-lowering and anti-cancer drugs do not benefit from preventing severe complications such as cardiovascular events and deaths. This implies that diagnosis and treatment in modern medicine in many circumstances is imprecise...

Sex and gender are critical contributors to overall health and disease, and considering both in research informs the development of prevention strategies and treatment interventions for both men and women. The National Institutes of Health (NIH) Office of Research on Women's Health sponsored a preconference workshop on this topic at the 24th Annual Women's Health Congress, which was held in Crystal City, VA, in April 2016. The workshop featured presentations by NIH intramural and extramural scientists who presented data on a variety of topics including polycystic kidney disease, vaccine protection, depression, drug addiction, and cardiovascular disease...

Far from being just "bugs in our guts," the microbiota interacts with the body in previously unimagined ways. Research into the genome and the microbiome has revealed that the human body and the microbiota have a long-established but only recently recognized symbiotic relationship; homeostatic balance between them regulates body function. That balance is fragile, easily disturbed, and plays a fundamental role in human health-our very survival depends on the healthy functioning of these microorganisms. Increasing rates of cardiovascular, autoimmune, and inflammatory diseases, as well as epidemics in obesity and diabetes in recent decades are believed to be explained, in part, by unintended effects on the microbiota from vaccinations, poor diets, environmental chemicals, indiscriminate antibiotic use, and "germophobia...

Background: Influenza and pneumococcal disease contribute substantially to the burden of preventable disease in the United States. Despite quality measures tied to immunization rates, health systems have struggled to achieve these targets in the inpatient setting. Pharmacy departments have had success through implementation of pharmacist standing order programs (SOP); however, these initiatives are labor-intensive and have not resulted in 100% immunization rates. Objective: The objective of this study was to evaluate a pilot utilizing pharmacy technician interventions, in combination with a nursing SOP, to improve vaccination rates of hospitalized patients for influenza and pneumococcal disease...

Systemic lupus erythematosus (SLE) is a chronic, systemic autoimmune disease characterized by autoantibody production, complement activation, and immune complex deposition. It predominantly affects young and middle-aged women. While improvements in the diagnosis and treatment of SLE have altered prognosis, morbidity and mortality rates remain higher than the general population. In addition to renal injury, cardiovascular disease, and infection, malignancy is known to be a significant cause of death in this population...

Due to the wide interaction between the respiratory and the circulatory systems, influenza and pneumococcal vaccinations are recommended in the prevention and treatment of cardiovascular diseases. The review summarizes the results of recent studies and meta-analyses demonstrating that in this group of high-risk patients both vaccinations have potentially beneficial properties. However, in the era of Evidence Base Medicine, there is still a lack of randomized prospective clinical trials, especially those evaluating the effect of pneumococcal vaccination...

Purpose of review With established immunosuppressant treatment regimens for anti-neutrophil cytoplasm antibody-associated vasculitides (AAV), prognosis has significantly improved. The mainstay of treatment still comprises high-dose corticosteroids and cyclophosphamide for severe forms, although rituximab is being increasingly utilised instead of cyclophosphamide as induction therapy. AAV patients experience an excess of infections, malignancies and cardiovascular events as compared to the general population, which is a combination of the systemic inflammatory process associated with vasculitis and the adverse events from treatment...

Introduction; Adults, particularly those with underlying chronic conditions, eg, cardiovascular, liver, and pulmonary diseases and diabetes mellitus, have a persistent pneumococcal disease burden. Thirteen-valent pneumococcal conjugate vaccine (PCV13) is recommended in the United States for all adults aged ≥65 years and immunocompromised adults aged <65 years to protect against vaccine-serotype (VT) invasive pneumococcal disease (IPD) and pneumonia. PCV13 is not recommended for immunocompetent adults aged ≥18 years with comorbidities associated with increased pneumococcal disease risk...

Severe exacerbations of COPD, ie, those leading to hospitalization, have profound clinical implications for patients and significant economic consequences for society. The prevalence and burden of severe COPD exacerbations remain high, despite recognition of the importance of exacerbation prevention and the availability of new treatment options. Severe COPD exacerbations are associated with high mortality, have negative impact on quality of life, are linked to cardiovascular complications, and are a significant burden on the health-care system...

Methodological issues of how to use health state utility values (HSUVs) in decision models arise frequently, including the most appropriate evidence to use as the baseline (e.g. the baseline HSUVs associated with avoiding a particular health condition or event), how to capture changes due to adverse events and how to appropriately capture uncertainty in progressive conditions where the expected change in quality of life is likely to be monotonically decreasing over time. As preference-based measures provide different values when collected from the same patient, it is important to ensure that all HSUVs used within a single model are obtained from the same instrument where ever possible...

Atherosclerosis is a chronic inflammatory disease. Pathophysiological similarities between chronic infections and atherosclerosis triggered interest in a clinical association between these conditions. Various infectious microbes have been linked to atherosclerotic vascular disease in epidemiological studies. However, this association failed to satisfy the Koch's postulates of causation with multiple clinical trials demonstrating inefficacy of anti-infective therapies in mitigating atherosclerotic cardiovascular events...

It is known that the immune systems tend to weaken over time, putting elderly patients at higher risk for chronic diseases such as cardiovascular (CV) diseases, diabetes, chronic renal disorders and their complication as well as infectious disease leading to an increased mortality and morbidity rates in patients over 65 years old. Vaccination, a prophylactic treatment strategy, means that immunogenic materials from pathogens (or tumours) are administered to generate an adequate immune response specifically to these antigens...
