Mothers transmitting hepatitis B to children as broken hospital procedures plague Europe
Procedures to prevent the direct transmission of hepatitis B virus (HBV) from mother to child, particularly during and after pregnancy, have significant fragmentation and gaps
2021-06-05
(Press-News.org) (Geneva, 5 June 2021) Procedures to prevent the direct transmission of hepatitis B virus (HBV) from mother to child, particularly during and after pregnancy, have significant fragmentation and gaps, a new survey presented at the 6th World Congress of Paediatric Gastroenterology, Hepatology and Nutrition has shown.
The results, based on 76 delivery hospitals from ten major European countries*, identified significant variances in maternal HBV screening frequency during pregnancy: 53% in the first trimester, 1% in the second trimester and 46% in the third trimester. Alarmingly, only 38% of those women who tested positive with high HBV-DNA levels were treated during the final 12 weeks of pregnancy despite the vast majority of centres (88%) having written protocols for preventing mother-to-child transmission of HBV infection.
The prevention of direct transmission of HBV infection from mother to child is seen as a crucial step towards reducing its incidence as part of the World Health Organization (WHO) global health sector strategy for eliminating viral hepatitis as a major public health threat by 2030. If current trends continue, 19 million hepatitis-related deaths are anticipated from 2015 to 2030.2 By identifying the barriers and challenges, this research represents a key step in preventing this outcome and towards full adherence to international guidelines across European countries.
The new survey also discovered that post-vaccination testing of infants from HBV positive mothers is provided in less than half of centres, even though 10-20% of vaccinated infants still acquire HBV when their mothers had high levels of the virus. This means that infected children, despite being immunised, may not be diagnosed. This is particularly significant in cases where the determination of HBV status occurs in the third trimester, which may be too late to start antiviral therapy in women with high HBV-DNA levels. To compound this concerning revelation further, inconsistency has been reported across all centres on the timing of the HBV vaccine schedule.
Lead author on the research, Michele Pinon from the University of Turin, commented: 'This survey provides a strong indication that significant variance and gaps exist in hospital policies and procedures to prevent direct mother-to-child transmission of HBV across Europe. There is a clear need to implement a multidisciplinary clinical pathway involving obstetricians, neonatologists, and hepatologists, with a stronger connection between the phases before, during and after birth.'
The web-based survey, supported by Penta Foundation and distributed by INCIPIT (Italian Network for Paediatric Clinical Trials), was focused on the prevention strategies adopted before, at, and after birth. A single response was provided in response to the survey by the most experienced physician(s) from each of the 76 participating hospitals.
Speaking on the survey, Chair of the ESPGHAN Hepatology Committee, Giuseppe Indolfi, who was also involved in the research, stated, 'The disjointed and inconsistent nature of practices for prevention of HBV vertical transmission across Europe revealed by this survey is a considerable cause for concern. Procedures must be rectified as soon as possible as we build towards achieving the WHO goal to eradicate the threat of viral hepatitis by 2030.'

MADISON, Wis. -- If you're wearing gold jewelry right now, there's a good chance it came from an illegal mining operation in the tropics and surfaced only after some rainforest was sacrificed, according to a team of University of Wisconsin-Madison researchers and alumni who studied regulatory efforts to curb some of these environmentally damaging activities in the Amazon.
The researchers, including UW-Madison geography Professor Lisa Naughton, investigated mining-related deforestation in a biodiverse and ecologically sensitive area of the Peruvian Amazon to see whether formalizing and legalizing these mining operations might curb some of their negative effects.
Their study, published June 2 in the journal Environmental Research Letters, was co-authored by a group including UW-Madison ...

In a large, international retrospective study, men at high risk for death from prostate cancer had a significant reduction in all-cause mortality if treated with radiation shortly after surgery.
Prostate cancer is one of the most common forms of cancer among men, and about 1-in-8 of them will be diagnosed with it during their lifetime. While most men are cured with available treatment, there remains a group at high risk for death. In the United States in 2020, 33,330 men died from the disease, making prostate cancer the second leading cause of cancer death for men in this country. Therefore, among those at highest risk of recurrence, metastasis, and death from prostate cancer, understanding what steps can be taken to lower these risks could save and extend lives.

At Boston University, a team of researchers is working to better understand how language and speech is processed in the brain, and how to best rehabilitate people who have lost their ability to communicate due to brain damage caused by a stroke, trauma, or another type of brain injury. This type of language loss is called aphasia, a long-term neurological disorder caused by damage to the part of the brain responsible for language production and processing that impacts over a million people in the US.
"It's a huge problem," says Swathi Kiran, director of BU's Aphasia Research Lab, and College of Health & Rehabilitation Sciences: Sargent College associate dean for research and ...

The new drug sotorasib reduces tumor size and shows promise in improving survival among patients with lung tumors caused by a specific DNA mutation, according to results of a global phase 2 clinical trial. The drug is designed to shut down the effects of the mutation, which is found in about 13% of patients with lung adenocarcinoma, a common type of non-small-cell lung cancer.
The Food and Drug Administration approved sotorasib May 28 as a targeted therapy for patients with non-small-cell lung cancer whose tumors express a specific mutation -- called ...

PROVIDENCE, R.I. [Brown University] -- A new study of monsoon rainfall on the Indian subcontinent over the past million years provides vital clues about how the monsoons will respond to future climate change.
The study, published in Science Advances, found that periodic changes in the intensity of monsoon rainfall over the past 900,000 years were associated with fluctuations in atmospheric carbon dioxide (CO2), continental ice volume and moisture import from the southern hemisphere Indian Ocean. The findings bolster climate model predictions that rising CO2 and higher global temperatures will lead to stronger monsoon seasons.
"We show that over the last 900,000 years, higher CO2 levels along with associated changes in ice volume and moisture ...

Accurate soft tissue measurements are critical when making reconstructions of human ancestors, a new study from the University of Adelaide and Arizona State University has found.
"Reconstructing extinct members of the Hominidae, or hominids, including their facial soft tissue, has become increasingly popular with many approximations of their faces presented in museum exhibitions, popular science publications and at conference presentations worldwide," said lead author PhD student Ryan M. Campbell from the University of Adelaide.
"It is essential that accurate facial soft tissue thickness measurements are used when reconstructing the faces of hominids to reduce the variability exhibited in reconstructions of the same individuals."
Hominids have been readily accepted ...

A new study shows that substantial amounts of carbon dioxide were released during the last millennium because of crop cultivation on peatlands in the Northern Hemisphere.
Only about half of the carbon released through the conversion of peat to croplands was compensated by continuous carbon absorption in natural northern peatlands.
Peatlands are a type of wetland which store more organic carbon than any other type of land ecosystem in the world.
Due to waterlogged conditions, dead plant materials do not fully decay and carbon accumulates in peatlands over thousands of years.
Therefore, natural peatlands help to cool the climate by capturing carbon dioxide (CO2) from the atmosphere ...
