Displaying lab test costs in health records doesn't deter doctors from ordering them

Jue, 04/20/2017 - 22:00
Hospitals nationwide are seeking ways to use price transparency -- displaying the price of lab tests at the time when doctors are placing the order -- to nudge doctors to consider whether the benefits are worth the cost. But, results of a new study show that simply displaying the Medicare allowable fees did not have an overall impact on how clinicians ordered these tests. The results are published today in JAMA Internal Medicine and presented at the Society of General Internal Medicine annual meeting in Washington, DC.

Using CRISPR to reverse retinitis pigmentosa and restore visual function

Jue, 04/20/2017 - 22:00
Using the gene-editing tool CRISPR/Cas9, researchers at University of California San Diego School of Medicine and Shiley Eye Institute at UC San Diego Health, with colleagues in China, have reprogrammed mutated rod photoreceptors to become functioning cone photoreceptors, reversing cellular degeneration and restoring visual function in two mouse models of retinitis pigmentosa.

Blood donor screening for hepatitis E reveals incidence is higher than previously reported

Jue, 04/20/2017 - 22:00
Results from a study presented today found that the incidence of HEV RNA in asymptomatic blood donors from Germany is higher than previously reported. The study, presented at The International Liver Congress™ 2017 in Amsterdam, The Netherlands, showed that 0.11 percent of donations tested were HEV RNA positive and that one of the asymptomatic HEV RNA positive donors had previously donated HEV RNA positive blood products, which were then transfused into nine immunocompromised patients.

Treatment of HCV allows for sustained removal from the liver transplant waiting list

Jue, 04/20/2017 - 22:00
A new European study presented today demonstrated that patients with chronic HCV and severe liver damage, taken off the liver transplant list as a result of successful DAA therapy, had a favorable outcome over a year later. The study, presented at The International Liver Congress™ 2017 in Amsterdam, The Netherlands, showed that 26.7 percent of patients could be removed from the waiting list due to clinical improvement.

Diet high in animal protein is associated with NAFLD in overweight people

Jue, 04/20/2017 - 22:00
A large epidemiological study presented today found that a diet high in animal protein was associated with a higher risk of non-alcoholic fatty liver disease (NAFLD), a condition in which fat builds up in the liver. These findings from The Rotterdam Study, presented at The International Liver Congress™ 2017 in Amsterdam, The Netherlands, also showed that fructose consumption per se might not be as harmful as previously assumed.

Fecal microbiota transplants improve cognitive impairment caused by severe liver disease

Jue, 04/20/2017 - 22:00
A study presented today found that fecal transplantation of bacteria from one healthy donor into patients that suffer from hepatic encephalopathy, is safe and improves cognitive function compared with standard of care treatment for the condition. Presented at The International Liver Congress™ 2017 in Amsterdam, The Netherlands, the study results also demonstrated that the number of hospitalizations following fecal transplantation plus antibiotics was two, compared to the standard of care arm, which was 11.

Investigational dose of oral interferon-free treatment can cure hepatitis C in children

Jue, 04/20/2017 - 22:00
A study presented today that evaluated an investigational dosage of once-daily ledipasvir 45 mg/sofosbuvir 200 mg (LDV/SOF) in children aged six to 11 years infected with HCV, found that 99 percent of children had undetectable levels of HCV-RNA 12 weeks after treatment. The study, presented at The International Liver Congress™ 2017 in Amsterdam, The Netherlands, showed that the fixed-dose combination of LDV/SOF was well-tolerated, and no patients experienced serious adverse events related to the study drug.

Study demonstrates the efficacy of an investigational treatment in hepatitis C subgroup

Jue, 04/20/2017 - 22:00
Study results presented today demonstrate that the oral, once-daily treatment regimen of glecaprevir/pibrentasvir resulted in 95 percent sustained virologic response rates 12 weeks post treatment in patients with HCV genotype 3. In the ENDURANCE-3 study, presented at The International Liver Congress™ 2017 in Amsterdam, The Netherlands, patients infected with HCV genotype 3 without cirrhosis and who had no previous treatment history were treated with the new regimen for eight or 12 weeks, which was well tolerated.

Nivolumab produces durable responses & long-term survival in severe liver cancer patients

Jue, 04/20/2017 - 22:00
Results from the CheckMate 040 study presented today found that nivolumab produces durable responses with long-term survival rates, regardless of whether or not patients were infected with Hepatitis B or C. Interim results from the study, presented at The International Liver Congress™ 2017 in Amsterdam, The Netherlands, showed that the overall objective response rate (ORR) was 14.5 percent and ORR by investigator assessment was 19.3 percent in sorafenib-experienced patients in the dose expansion phase of CheckMate 040.

Majority of parents plan to use telemedicine for pediatric care

Mié, 04/19/2017 - 22:00
New findings released today by Nemours Children's Health System show 64 percent of parents polled have used or plan to use telemedicine within the next year for their child. The survey, Telemedicine in America 2017: Parents Use of Virtual Visits, found that only 15 percent of parents have tried these services, but a strong majority is receptive to online doctor visits for common childhood ailments and routine well-child visits.

Plant's parent genes cooperate in shaping their child

Mié, 04/19/2017 - 22:00
Plant biologists discovered for the first time on how factors arising from the mother and father in flowering plants cooperate to develop the shape of their child. Until now, it has been unknown whether paternal factors cooperate or conflict with each other to bring about zygote asymmetry. The outcome of this discovery is expected to shed light on the exact mechanism of plant body shape formation and possibly lead to the generation of new hybrid plants.
