Screening Young Adults for Hepatitis C with Rapid Testing!

Hepatitis C (HCV) is a viral infection that affects the liver and an estimated 3.2 million people in the USA are infected with HCV, and most do not feel ill or know that they are infected. Since 2010, acute cases of HCV have more than doubled, with new cases predominantly among young, white individuals with a history of injection drug use.

The current recommendations are that doctors screen patients at high-risk for contracting HCV, which include but are not limited to people born between 1945 and 1965, those diagnosed with HIV, children born to HCV-positive women and individuals who engage in injection drug use (PWID), among other select populations at high risk. This strategy is called "targeted" screening. "Routine" screening, as defined in the study, tests all individuals in a community with a high prevalence of HCV.

There are two ways to perform these screenings. Rapid testing is when results are given on the same day that the sample is drawn. Standard testing requires patients to return for a second appointment to get the results. Scientists at Boston Medical Center (Boston, MA, USA) and their colleagues evaluated the clinical benefits and cost-effectiveness of testing strategies among 15 to 30-year-olds at urban community health centers. They developed a decision analytic model to project quality-adjusted life years (QALYs), lifetime costs (2016 USDs) and incremental cost-effectiveness ratios (ICER) associated with nine strategies for one-time testing. The strategies differed in three ways: targeted versus routine testing; rapid finger stick versus standard venipuncture; and ordered by physician versus counselor/tester using standing orders.

The team found that compared to targeted risk-based testing (current standard of care), routine testing increased lifetime medical cost by USD 80 and discounted QALYs by 0.0013 per person. Across all strategies rapid testing provided higher QALYs at a lower cost per QALY gained, and was always preferred. Counselor-initiated routine rapid testing was associated with an ICER of USD 71,000/QALY gained. Results were sensitive to offer and result receipt rates. Counselor-initiated routine rapid testing was cost-effective (ICER greater than USD 100,000/QALY) unless the prevalence of PWID was greater than 0.59%, HCV prevalence among PWID less than 16%, reinfection rate greater than 26 cases per 100 person-years, or reflex confirmatory testing followed all reactive venipuncture diagnostics.

Sabrina A. Assoumou, MD, MPH, an infectious disease physician and lead author of the study, said, “When standard testing was applied, patients were less likely to come back for that second appointment to get their results, which in turn meant more people weren't getting the treatment they so desperately needed. Our results indicate that we must initiate rapid testing strategies so that more people will know their status and get treatment more quickly.” The study was published on September 9, 2017, in the journal Clinical Infectious Diseases.

From 230,000 patients to extinct in 15 years: pathology and new drugs key to defeating hepatitis C

An estimated 230,000 Australians have chronic hepatitis C, and a quarter of cases are undiagnosed.

Hepatitis C inflames the liver and unlike the A and B viruses there is no vaccine available. Pathology is important for diagnosing the virus.

Many people with hepatitis C may not experience symptoms, but left untreated the disease can cause cirrhosis (scarring of the liver), which in a small number of cases can lead to liver cancer.

Short-Chain Fatty Acids In Control Of Body Weight And Insulin Sensitivity

The connection between the gut microbiota and the etiology of obesity and cardiometabolic disorders is increasingly being recognized by clinicians. Our gut microbiota might affect the cardiometabolic phenotype by fermenting indigestible dietary components and thereby producing short-chain fatty acids (SCFA). These SCFA are not only of importance in gut health and as signaling molecules, but might also enter the systemic circulation and directly affect metabolism or the function of peripheral tissues.

In this Review, we discuss the effects of three SCFA (acetate, propionate and butyrate) on energy homeostasis and metabolism, as well as how these SCFA can beneficially modulate adipose tissue, skeletal muscle and liver tissue function.

Liver Cancer Risk Influenced By Blood Selenium Levels

The risk of developing liver cancer may be significantly higher for people who have low levels of the nutrient selenium in their blood, suggests a new study published in the American Journal of Clinical Nutrition.

Selenium is a trace mineral present in soil, animal products, and plant-based foods, including seafood, Brazil nuts, organ meats, milk, and eggs.

The selenium content of food varies greatly, as it depends on how much of the element is in the plants animals consume, as well as how much is in the soil in which plants grow.

According to the National Institutes of Health (NIH), selenium is essential for human health, with beneficial roles for reproduction, the immune system, and DNA synthesis.

Studies have also shown that selenium has antioxidant properties, meaning it can protect against oxidative stress - the process by which uncharged molecules called free radicals damage cells.

Amazing Foods That Help Prevent Fatty Liver

Have you been suffering from abdominal pain, nausea, vomiting, fatigue and loss of appetite quite often?

Then, you need to watch out, as these could be the symptoms of a fatty liver disease. In case of fatty liver disease, one tends to develop excess fats within the liver.

Liver is one of the most important vital organs of our body. A certain amount of fat in the liver is normal, but when it increases above the normal (above 5 per cent of the organ's weight), then the person could be at the risk of developing fatty liver disease.

Gallbladder Problems: Signs, Symptoms, Treatments and Outlooks

Most people don't pay much attention to their gallbladder until it starts causing trouble. However, when the gallbladder starts acting up, it can be quite painful and require immediate action.

This article will look at what the gallbladder does, the symptoms of a problem with the gallbladder, treatment options, and long-term outlook.

What is the gallbladder?

The gallbladder is a 4-inch-long pear-shaped organ found under the liver in the upper right quadrant of the abdomen. It stores the bile the liver makes to digest fat.

Scientists are growing billions of blood cells in the lab

From helping humans live longer and hacking our performance, to repairing the body and understanding the brain, WIRED Health will hear from the innovators transforming this critical sector. Read all of our WIRED Health coverage here.

Jo Mountford is making billions of red blood cells in a laboratory in Glasgow. And now she wants to scale-up production. Big time.

Mountford, from the Institute of Cardiovascular and Medical Sciences at the University of Glasgow, started trying to create blood in the lab in 2007 and is now able to create it on demand.

In 2008, her team produced 100,000 red blood cells; by 2014 output had reached ten billion cells for the year. The ten billion cells were stored in 88 flasks and made up 8.8 litres of blood.

The team – funded by the Wellcome Trust and incorporating universities and organisations from around the UK – is now able to produce the cells in 30-31 days. "We can choose what blood group we make," Mountford told the audience at WIRED Health.
