Ultrasound-guided percutaneous needle biopsy excellent for small pleural lesions diagnosis
According to an open-access article in ARRS' American Journal of Roentgenology, ultrasound (US)-guided percutaneous pleural needle biopsy (PCPNB) has excellent diagnostic accuracy for small pleural lesions. ''In multivariable analysis,'' the authors concluded, ''pleural morphology on US and needle pathway length through the pleura independently predicted diagnostic yield,'' adding that if the pleura is nodular or thicker than 4.5 mm on CT, US-guided PCPNB is justifiable as an initial or repeat diagnostic test.

A malformation illustrates the incredible plasticity of the brain
One in 4,000 people is born without a corpus callosum, a brain structure consisting of neural fibres that are used to transfer information between hemisphere. 25% of them do not have any symptoms. Neuroscientists from the University of Geneva discovered that when the neuronal fibres that act as a bridge between the hemispheres are missing, the brain reorganises itself and creates an impressive number of connections inside each hemisphere, recreating connections using alternative neural pathways.

New method for in utero 4D imaging of baby hearts may aid diagnosis of congenital heart disease
Researchers at King's College London have developed a new method for helping detect congenital heart disease of a baby in pregnant mothers using MRI.

The journal is published in the Lippincott portfolio by Wolters Kluwer. (2020-09-08)

Chemotherapy drug more effective when combined with microbubbles
Hepatocellular carcinoma is usually treated by blocking the flow of blood to the tumor to induce cancer cell death, but the common treatment, transarterial chemoembolization, is invasive and too imprecise to be a local drug delivery method. Aiming to increase the precision, researchers at Tulane University created a treatment that involves vaporizing tiny droplets of perfluorocarbon, a common organic material composed of carbon and fluorine. The method of gas embolization is published in APL Bioengineering. (2020-09-08)

Thyroid inflammation linked to anxiety disorders
Patients with autoimmune inflammation of their thyroid may be at greater risk of developing anxiety, according to a study being presented at e-ECE 2020. The study found that people with anxiety may also have inflammation in their thyroid gland that can be reduced by taking the non-steroidal anti-inflammatory, ibuprofen. These findings suggest that thyroid function may play an important role in the development of anxiety disorders. (2020-09-06)

Buzzing to rebuild broken bone
Healing broken bones could get easier with a device that provides both a scaffold for the bone to grow on and electrical stimulation to urge it forward, UConn engineers report. Although minor bone breaks usually heal on their own, large fractures with shattered or missing chunks of bone are more difficult to repair. A biocompatible, dissolving polymer device can mimic the body's natural electrical field and help the cells regenerate. (2020-06-30)
