Bat Tick Found for the First Time in New Jersey

A tick species associated with bats has been reported for the first time in New Jersey and could pose health risks to people, pets and livestock, according to a Rutgers-led study in the Journal of Medical Entomology. This species (Carios kelleyi) is a “soft” tick. Deer ticks, which carry Lyme disease, are an example of “hard” ticks.

Dilated Blood Vessels in the Lung May Explain Low Oxygen Levels in Severe Cases of COVID-19

A new pilot study from the Icahn School of Medicine at Mount Sinai suggests that COVID-19 is causing significant dilation of the blood vessels of the lung, specifically the capillaries.

Ultrasound-Assisted Molecule Delivery Looks to Preserve Blood for Years

Blood can typically be stored for only six weeks after donation, but a potential solution attempts to dry blood by using a sugar-based preservative. New work in ultrasound technology looks to provide a path to inserting these sugars into human red blood cells, allowing the molecule trehalose to enter the cells and prevent their degradation when dried for preservation. The researchers discuss their work in this week’s Biomicrofluidics.

Vitamin D Boosts Chances of Walking After Hip Fracture

Senior citizens who are not vitamin D deficient have a better chance of walking after hip fracture surgery, according to a Rutgers-led study. The findings in The American Journal of Clinical Nutrition suggest that vitamin D deficiency could limit mobility in older adults, said senior author Sue Shapses, a professor in the Department of Nutritional Sciences at the School of Environmental and Biological Sciences at Rutgers University–New Brunswick.

Robot Uses Artificial Intelligence and Imaging to Draw Blood

Rutgers engineers have created a tabletop device that combines a robot, artificial intelligence and near-infrared and ultrasound imaging to draw blood or insert catheters to deliver fluids and drugs. Their research results, published in the journal Nature Machine Intelligence, suggest that autonomous systems like the image-guided robotic device could outperform people on some complex medical tasks.

Blood Shortage on the Battlefield? Just Make It On-site

A new program launched by the Department of Defense could be the answer to blood shortages on the battlefield, other remote locations, and in hospitals. The Uniformed Services University of the Health Sciences’ 4D Bio3 On-Demand Blood Program, or 4D Bio3 Blood, has developed highly efficient protocols and technology to generate red blood cells from stem cells. A key part of this technology is large-scale cell expansion at low cost, producing sufficient red blood cells for treatment in trauma care. This technology is also being adapted to create neutrophils, ultimately allowing for whole blood transfusion using these methods in the future.

New Robot Does Superior Job Sampling Blood

In the future, robots could take blood samples, benefiting patients and healthcare workers alike. A Rutgers-led team has created a blood-sampling robot that performed as well or better than people, according to the first human clinical trial of an automated blood drawing and testing device.

Simulations Characterize Turbulence Caused by Common Connection for Dialysis

The complex interplay among the arteriovenous grafts, the vessels they connect, and the blood they transport has been difficult to simulate with computers, but one new method provides a way. Researchers report in Physics of Fluids on a series of simulations that reconstructed the fluid dynamics affected by the insertion of an AVG.

Moderate to Heavy Drinking During Pregnancy Alters Genes in Newborns, Mothers

Mothers who drink moderate to high levels of alcohol during pregnancy may be changing their babies’ DNA, according to a Rutgers-led study.
