Simple steps can safeguard against Ebola transmission through organ donation

2014-12-15
(Press-News.org) While serious infections can be transmitted from donated organs, the risk of passing Ebola virus disease from an organ donor to a recipient is extremely small. In a new editorial published in the American Journal of Transplantation, experts explain how simple assessments of donors can help ensure that the organ supply is safe, while having little impact on the donor pool.

Despite screening all organ donors for infection, on rare occasions an organ donor will transmit an unexpected infection to a recipient. Because cases of Ebola virus disease have occurred in the United States recently, clinicians want to make sure that appropriate steps are taken to reduce the already low risk that Ebola virus could be unknowingly transmitted from donor to recipient. Experts note that simple screening questions, many of which are already asked, can be used to assess if donors have risk for harboring Ebola virus disease. Also, investing in new laboratory-based testing is likely not practical or effective. "Thousands of people die in the United States each year waiting for an organ transplant, and we think it is very important not to overreact to the very low risk that a potential donor might have the Ebola virus, and, as a consequence, unnecessarily discard potentially life-saving organs," said lead author Daniel Kaul, MD, who is the director of the transplant infectious disease division at the University of Michigan in Ann Arbor and the chair of the United Network for Organ Sharing's Disease Transmission Advisory Committee.

Dr. Kaul and his colleagues suggest that individuals who travelled in the past three weeks to the countries in Africa where Ebola virus is active, as well as health care workers and others in the United States who were recently exposed to someone infected with Ebola virus, should not donate organs. While it is difficult to know how long a person should be kept from donating after exposure to the Ebola virus, they feel that a 21-day exclusion period is reasonable. "We think that after the 21-day period, doctors taking care of the patients involved could consider using those organs after talking with the potential recipients if that organ might be the recipient's best chance to survive," said Dr. Kaul.

Are you genetically predisposed to antisocial behavior?

2014-12-15
Both positive and negative experiences influence how genetic variants affect the brain and thereby behaviour, according to a new study. "Evidence is accumulating to show that the effects of variants of many genes that are common in the population depend on environmental factors. Further, these genetic variants affect each other," explained Sheilagh Hodgins of the University of Montreal and its affiliated Institut Universitaire en Santé Mentale de Montréal. "We conducted a study to determine whether juvenile offending was associated with interactions between three ...

Baby cells learn to communicate using the lsd1 gene
2014-12-15
Baltimore MD-- We would not expect a baby to join a team or participate in social situations that require sophisticated communication. Yet, most developmental biologists have assumed that young cells, only recently born from stem cells and known as "progenitors," are already competent at inter-communication with other cells. New research from Carnegie's Allan Spradling and postdoctoral fellow Ming-Chia Lee shows that infant cells have to go through a developmental process that involves specific genes before they can take part in the group interactions that underlie ...

University of Toronto cell biologists discover on-off switch for key stem cell gene

University of Toronto cell biologists discover on-off switch for key stem cell gene
2014-12-15
TORONTO, ON - Consider the relationship between an air traffic controller and a pilot. The pilot gets the passengers to their destination, but the air traffic controller decides when the plane can take off and when it must wait. The same relationship plays out at the cellular level in animals, including humans. A region of an animal's genome - the controller - directs when a particular gene - the pilot - can perform its prescribed function. A new study by cell and systems biologists at the University of Toronto (U of T) investigating stem cells in mice shows, for the ...

Fat cells reprogrammed to increase fat burning

Fat cells reprogrammed to increase fat burning
2014-12-13
White adipose tissue stores excess calories as fat that can be released for use in other organs during fasting. Mammals also have small amounts of brown adipose tissue, which primarily acts as an effective fat burner for the production of heat. Now researchers from the University of Southern Denmark have uncovered the mechanism by which white fat cells from humans gets reprogrammed to become browner. Browning of white adipose tissue increases the energy consumption of the body and therefore constitutes a potential strategy for future treatment of obesity. The challenge ...

Immune cells in brain respond to fat in diet, causing mice to eat

2014-12-13
Immune cells perform a previously unsuspected role in the brain that may contribute to obesity, according to a new study by UC San Francisco researchers. When the researchers fed mice a diet high in saturated milk fats, microglia, a type of immune cell, underwent a population explosion in the brain region called the hypothalamus, which is responsible for feeding behavior. The researchers used an experimental drug and, alternatively, a genetic approach to knock out these microglia, and both strategies resulted in a complete loss of microglia-driven inflammation in the ...

New TGen test uses the unique genetics of women to uncover neurologic disorders

2014-12-12
PHOENIX, Ariz. -- Dec. 12, 2014 -- Using a basic genetic difference between men and women, the Translational Genomics Research Institute (TGen) has uncovered a way to track down the source of a neurological disorder in a young girl. TGen's discovery relies on a simple genetic fact: Men have one X and one Y chromosome, while women have two X chromosomes. This women-only factor was leveraged by TGen investigators to develop a highly accurate method of tracking down a previously unrecognized disorder of the X-chromosome. The study of a pre-teen girl, who went years ...

Disney Research builds computer models to analyze play in pro basketball and soccer

2014-12-12
With the ball at the three-point line near the top of the key, what will Tim Duncan of the NBA's San Antonio Spurs do? Pass to a player posting up? Or does he take a shot? An analysis by Disney Research of player tracking data, however, suggests the highest probability is a pass to guard Tony Parker on his left. It's just one play, by one player, in one sport - and perhaps not that hard for the average courtside observer to anticipate - but with the field of sports becoming more driven by sports analytics, predicting the next thing that a player will do has become a major ...

Expected stay rates of US and foreign doctoral graduates diverge with time

2014-12-12
A new National Science Foundation (NSF) report reveals the number of U.S. citizen doctoral graduates in science, engineering and health fields, who remain in the United States, tracks closely with their intent to stay in the United States at the time of graduation. However, there are noticeable differences for doctoral graduates who were temporary visa holders at the time of graduation. According to the report, 96.4 percent of U.S. citizen doctoral graduates from academic years 2001-09 reported their intent to live in the United States, a measure referred to as the expected ...

All children should have vision health screening between age 3 and 6, expert panel recommends

2014-12-12
December 12, 2014 - All children should undergo vision health screening between age 36 and 72 months--preferably every year--using evidence-based test methods and with effective referral and follow-up, according to recommendations published in the January issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. The National Expert Panel to The National Center for Children's Vision Health makes recommendations for vision health screening in ...

New theory suggests alternate path led to rise of the eukaryotic cell

2014-12-12
MADISON, Wis. - As a fundamental unit of life, the cell is central to all of biology. Better understanding how complex cells evolved and work promises new revelations in areas as diverse as cancer research and developing new crop plants. But deep thinking on how the eukaryotic cell came to be is astonishingly scant. Now, however, a bold new idea of how the eukaryotic cell and, by extension, all complex life came to be is giving scientists an opportunity to re-examine some of biology's key dogma. All complex life -- including plants, animals and fungi -- is made up of ...
