Health: All Adults 18-79 Should Be Screened For Hepatitis C Virus (HCV)

From a Stanford University online article (March 2, 2020):

Health Policy Stanford“The opioid epidemic has added fuel to the HCV fire, substantially increasing transmission,” said Owens. “HCV is now an enormous public health problem, affecting a much broader age range of people than before. Fortunately, we have the tools to identify people and treatment is now successful in the vast majority of patients, so screening can prevent the mortality and morbidity from HCV.”

A task force of national health experts recommends clinicians screen all adults 18 to 79 for the hepatitis C virus (HCV), noting that the viral infection is now associated with more deaths in the United States than the top 60 reportable infectious diseases combined. Many people are unaware they are carrying the viral infection.

“People with hepatitis C do not always feel sick and may not know they have it,” says chair of the U.S. Preventive Services Task Force Douglas K. Owens, M.D, M.S. “Screening is key to finding this infection early, when it’s easier to treat and cure, helping reduce illnesses and deaths.”

Owens, who is the director of Stanford Health Policy and the Henry J. Kaiser, Jr., Professor of Medicine, said the opioid epidemic now plays an important role in the prevalence of HCV. There are more than three times the number of acute HCV cases than a decade ago, particularly among young, white, injection drug users who live in rural areas. Women aged 15 to 44 have also been hit hard by the virus that is spread through contaminated blood.

One in 4 people in the US has difficulty paying the cost of their prescription medications. This stark fact was recently reported in a 2019 Kaiser Family Foundation public opinion poll among a nationally representative random sample of 1205 adults.1 Persons who reported having the greatest difficulty affording their prescription drugs were those who most needed them, including those who took 4 or more prescription drugs, spent $100 or more per month on their drugs, and reported being in fair or poor health.

Study: “Dysfunctional And Variable Sleep” Increases Risks Of Cardiovascular Disease

From a MedPageToday.com online article (March 2, 2020):

Journal of the American College of CardiologyDysfunctional sleep likely is by far the most prevalent comorbidity in CVD. This makes it essential to explore the nature of sleep, but this is reliant on the enthusiasm of clinician scientists,” according to the editorialists.

“In modern society, both the quantity and quality of sleep are negatively influenced by factors such as longer hours of work, more shift work, artificial light and cell phones, all leading to self-reported daytime symptoms such as fatigue, tiredness, and sleepiness,”

A larger range in individual sleep duration and sleep timing across 7 days of wrist actigraphy was associated with significantly more CVD events over a median 4.9 years of follow-up (P=0.002 for both trends).
