High drug price associated with decreased treatment retention for patients with chronic liver disease

2023-08-24
(Press-News.org) MINNEAPOLIS/ST. PAUL (08/24/2023) — Researchers from the University of Minnesota Medical School and College of Pharmacy have found that high costs for hepatic encephalopathy treatment in patients with end-stage liver disease were associated with decreased treatment retention for patients. The study results were recently published in Hepatology Communications.

Hepatic encephalopathy is the loss of brain function that occurs in people with severe liver disease. The condition is associated with high morbidity and mortality. The drug treatment rifaximin is commonly used to treat hepatic encephalopathy, yet treatment retention remains low.

“Our research demonstrates that the cost of rifaximin is too high in the United States. Individuals with scarred livers, who have a higher out-of-pocket cost, are more likely to not fill their prescription for their medication, which can result in falls, hospitalizations and other poor outcomes,” said Elizabeth Aby, MD, an assistant professor at the University of Minnesota Medical School and transplant hepatologist at M Health Fairview. “Clinicians and policy makers need to be aware of the impact that out-of-pocket costs have on patients’ medication adherence for rifaximin. Active measures must be taken to address this issue.”

The study included more than 6,800 patients with cirrhosis — a condition where the liver is scarred from long term damage — and hepatic encephalopathy. The research team’s analysis found patients who are younger and have metastatic cancer or depression are less likely to take their medication. 

The research team suggests clinicians screen patients for financial insecurity and the potentially harmful effect the high cost of treatment could have on the patient, as well as involving social workers and financial assistance early. Additionally, further steps are needed to lower the cost of the drug.

Optimizing tobacco cessation treatment with lung cancer screening

2023-08-24
MINNEAPOLIS/ST. PAUL (08/24/2023) —Lung cancer is the deadliest cancer in the United States, and 80% of lung cancer deaths are linked to one risk factor: smoking. While lung cancer screenings are a critical part of prevention and treatment for the disease and 15 million Americans qualify for yearly screenings, over half those eligible for screenings are still actively smoking. Without standard smoking cessation measures in place, the benefits of the screenings have not been fully realized.  New ...

New quantum device generates single photons and encodes information

New quantum device generates single photons and encodes information
2023-08-24
A new approach to quantum light emitters generates a stream of circularly polarized single photons, or particles of light, that may be useful for a range of quantum information and communication applications. A Los Alamos National Laboratory team stacked two different, atomically thin materials to realize this chiral quantum light source. “Our research shows that it is possible for a monolayer semiconductor to emit circularly polarized light without the help of an external magnetic field,” ...

Making materials more durable through science

Making materials more durable through science
2023-08-24
ALBUQUERQUE, N.M. — A team at Sandia National Laboratories developed a molecule that helps change the way some materials react to temperature fluctuations, which makes them more durable. It’s an application that could be used in everything from plastic phone cases to missiles. Polymers, which include various forms of plastics, are made up of many smaller molecules, bonded together. This bond makes them especially strong and an ideal product to be used to protect delicate components in a wide variety of items. But with time, use and exposure to different environments, all materials begin to deteriorate. Hot ...

New framework for oceanographic research provides potential for broader access to deep sea scientific exploration

New framework for oceanographic research provides potential for broader access to deep sea scientific exploration
2023-08-24
Woods Hole, Mass. (August 23, 2023) -- Scientific exploration of the deep ocean has largely remained inaccessible to most people because of barriers to access due to infrastructure, training, and physical ability requirements for at-sea oceanographic research. Now, a new and innovative framework for oceanographic research provides a way for shore-based scientists, citizen scientists, and the general public to seamlessly observe and control robotic sampling processes. The Shared Autonomy for Remote Collaboration (SHARC) framework “enables remote participants to conduct shipboard operations and control ...

How pre-eclampsia accelerates aging in women

2023-08-24
ROCHESTER, Minnesota — Pre-eclampsia, a life-threatening surge in blood pressure, is an enigmatic condition. Each year, it causes the deaths of more than 70,000 women worldwide. Because scientists do not know what causes it, they lack targeted strategies to treat it. Delivery, the only available therapy, is not the cure it is often made out to be, according to Vesna D. Garovic, M.D., Ph.D., a nephrologist at Mayo Clinic in Rochester, Minnesota, who has devoted her career to studying this common pregnancy complication. "Even after delivery, women ...

Sweet corn yield at the mercy of the environment, except for one key factor

Sweet corn yield at the mercy of the environment, except for one key factor
2023-08-24
URBANA, Ill. — A new analysis from the University of Illinois Urbana-Champaign and the USDA-Agricultural Research Service (ARS) has identified the top factors accounting for yield variability in processing sweet corn (used for canned and frozen products), including one within the control of processors.  “We used a very robust approach to account for sweet corn yield with field-level data across some 16,000 fields and 27 years. Year and production region were the two most important variables, which makes ...

Cambridge and ISPA scientists create a tool to identify individuals at risk of developing different myeloid leukemias

2023-08-24
Scientists have created a new test for identifying people at risk of developing acute myeloid leukaemia and related cancers, years before they do. The new platform, ‘MN-predict’, will allow doctors and scientists to identify those at risk and to design new treatments to prevent them from developing these potentially lethal cancers.   Researchers at the Wellcome-MRC Cambridge Stem Cell Institute (CSCI), the University of Cambridge’s Department of Haematology, and Instituto de Investigación Sanitaria del Principado de Asturias (ISPA) analysed data from more than 400,000 individuals participating ...

Repairing broken brain circuits may offer path to new Parkinson’s treatments

Repairing broken brain circuits may offer path to new Parkinson’s treatments
2023-08-24
GRAND RAPIDS, Mich. (August 24, 2023) — Van Andel Institute scientists have identified a series of processes that help the brain adapt to damage caused by breakdowns in circuits that govern movement, cognition and sensory perception. Because such breakdowns contribute to Parkinson’s disease, the findings may one day help researchers optimize current treatments or develop new ones that repair or bypass the broken circuits. A study describing the findings published this week in the journal Science Advances. “Our work highlights the importance ...

New method for revealing DNA repair “scars” ...

Study uncovers genetic risk factors for heart failure

2023-08-24
In a new study co-led by investigators at the United States Department of Veterans Affairs and Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, a global team of scientists conducted one of the largest genetic association studies on heart failure to date. Using genomic data from over 90,000 heart failure patients and more than a million controls, the team identified 39 genetic mutations associated with heart failure, 18 of which had not been reported previously. The researchers also pinpointed seven druggable proteins that, when targeted with specially ...
