Routine screening for BI-RADS lesions on automated whole-breast ultrasound

Return to routine screening for BI-RADS 3 lesions on supplemental automated whole-breast ultrasound substantially reduces the recall rate, while being unlikely to result in adverse outcome

Routine screening for BI-RADS lesions on automated whole-breast ultrasound
2021-07-15
(Press-News.org) Leesburg, VA, July 15, 2021--According to ARRS' American Journal of Roentgenology (AJR), return to routine screening for BI-RADS 3 lesions on supplemental automated whole-breast US (ABUS) substantially reduces the recall rate, while being unlikely to result in adverse outcome.

"This prospective study supports a recommendation for routine annual follow-up for BI-RADS 3 lesions at supplemental ABUS," wrote lead author Richard G. Barr of Northeastern Ohio Medical University in Rootstown.

From August 2013 to December 2016, Barr and colleagues' prospective study (NCT02650778) enrolled patients with BI-RADS 1 or 2 on screening mammography and breast density C or D to undergo supplemental ABUS, which was interpreted as BI-RADS 1, 2, 3, or 0. For ABUS BI-RADS 1, return to routine screening was recommended, whereas ABUS BI-RADS 0 lesions underwent targeted hand-held ultrasound.

In 2,257 women (mean age, 58 years), routine follow-up of BI-RADS 3 lesions detected on supplemental ABUS screening in women with dense breasts and any risk resulted in a recall rate of 3.8% (85/2,257), biopsy rate of 0.5% (12/2,257), and positive biopsy rate of 58.3% (7/12)--with no missed cancers (95% CI, 0.0-0.86%).

Noting that ABUS can help mitigate acquisition variability by standardizing the documentation, recording, and archiving of ultrasound images from the entire breast (excluding the axilla), Barr et al. reiterated that ABUS images of similar quality can be obtained from adequately trained ultrasonographers and mammographers.

"Avoiding earlier follow-up for these probably benign lesions can be associated with substantial cost savings," the authors of this AJR article added.

"Get out of the water!" Monster shark movies massacre shark conservation

2021-07-15
Undeniably the shark movie to end all shark movies, the 1975 blockbuster, Jaws, not only smashed box office expectations, but forever changed the way we felt about going into the water - and how we think about sharks. Now, more than 40 years (and 100+ shark movies) on, people's fear of sharks persists, with researchers at the University of South Australia concerned about the negative impact that shark movies are having on conservation efforts of this often-endangered animal. In a world-first study, conservation psychology researchers, UniSA's Dr Briana Le Busque and Associate Professor Carla Litchfield ...

Modified yeast inhibits fungal growth in plants

2021-07-15
About 70-80% of crop losses due to microbial diseases are caused by fungi. Fungicides are key weapons in agriculture's arsenal, but they pose environmental risks. Over time, fungi also develop a resistance to fungicides, leading growers on an endless quest for new and improved ways to combat fungal diseases. The latest development takes advantage of a natural plant defense against fungus. In a paper published in Biotechnology and Bioengineering, engineers and plant pathologists at UC Riverside describe a way to engineer a protein that blocks fungi from breaking down cell walls, as well as a way to produce this protein in quantity for external application as a natural fungicide. The work could lead to a new way of controlling plant disease that reduces reliance on conventional ...

Emotion, cooperation and locomotion crucial from an early age

Emotion, cooperation and locomotion crucial from an early age
2021-07-15
What are the fundamental skills that young children need to develop at the start of school for future academic success? While a large body of research shows strong links between cognitive skills (attention, memory, etc.) and academic skills on the one hand, and emotional skills on the other, in students from primary school to university, few studies have explored these links in children aged 3 to 6 in a school context. Researchers from the University of Geneva (UNIGE) and Valais University of Teacher Education, Switzerland (HEP-VS), in collaboration with teachers from Savoie in France and their pedagogical advisor, examined the links between emotion knowledge, cooperation, locomotor activity and numerical skills in 706 pupils aged 3 to 6. The results, to be read in the journal ...

Human waste contaminating urban water leads to 'superbug' spread -- study

2021-07-15
Contamination of urban lakes, rivers and surface water by human waste is creating pools of 'superbugs' in Low- and Middle-Income Countries (LMIC) - but improving access to clean water, sanitation and sewerage infrastructure could help to protect people's health, a new study reveals. Researchers studied bodies of water in urban and rural sites in three areas of Bangladesh - Mymensingh, Shariatpur and Dhaka. They found more antibiotic resistant faecal coliforms in urban surface water compared to rural settings, consistent with reports of such bacteria in rivers across Asia. Publishing their findings in mSystems today, researchers from the University of Birmingham and the International Centre for Diarrhoeal Disease Research, Bangladesh call for further research to quantify the drivers ...

Fossil rodent teeth add North American twist to Caribbean mammals' origin story

Fossil rodent teeth add North American twist to Caribbean mammals origin story
2021-07-15
GAINESVILLE, Fla. --- Two fossil teeth from a distant relative of North American gophers have scientists rethinking how some mammals reached the Caribbean Islands. The teeth, excavated in northwest Puerto Rico, belong to a previously unknown rodent genus and species, now named Caribeomys merzeraudi. About the size of a mouse, C. merzeraudi is the Caribbean's smallest known rodent and one of the region's oldest, dating back about 29 million years. It also represents the first discovery of a Caribbean rodent from a North American lineage, a finding that complicates an idea ...

Unlocking efficient light-energy conversion with stable coordination nanosheets

Unlocking efficient light-energy conversion with stable coordination nanosheets
2021-07-15
Converting light to electricity effectively has been one of the persistent goals of scientists in the field of optoelectronics. While improving the conversion efficiency is a challenge, several other requirements also need to be met. For instance, the material must conduct electricity well, have a short response time to changes in input (light intensity), and, most importantly, be stable under long-term exposure. Lately, scientists have been fascinated with "coordination nanosheets" (CONASHs), that are organic-inorganic hybrid nanomaterials in which organic molecules are bonded to metal atoms in a 2D network. The interest in CONASHs stems mainly from their ability to absorb light at multiple wavelength ranges and convert ...

Life-saving snake venom

2021-07-15
Indiana Jones hates snakes. And he's certainly not alone. The fear of snakes is so common it even has its own name: ophidiophobia. Kibret Mequanint doesn't particularly like the slithery reptiles either (he actually hates them too) but the Western University bioengineer and his international collaborators have found a novel use for snake venom: a body tissue 'super glue' that can stop life-threatening bleeding in seconds. Over the past 20 years, Mequanint has developed a number of biomaterials-based medical devices and therapeutic technologies - some of which are either licensed to medical companies or are in the advanced stage of preclinical testing. His latest collaborative research discovery ...
