Sickle Cell Disease

Sickle-cell disease, or sickle-cell anaemia (or drepanocytosis), is a life-long blood disorder characterized by red blood cells that assume an abnormal, rigid, sickle shape. Sickling decreases the cells' flexibility and results in a risk of various complications.

Understanding Sickle Cell Disease

World Sickle Cell Day is June 19 and was created by the United Nations in 2006 to raise global awareness for sickle cell disease as a public health problem. Sickle cell disease is an extremely debilitating medical condition.

Higher prevalence of anxiety disorders in youth with chronic medical conditions

Youth who report one of the seven chronic medical conditions (CMCs), including asthma, congenital heart disease, diabetes, epilepsy, inflammatory bowel disease, juvenile idiopathic arthritis, and sickle cell disease, are often diagnosed with an anxiety disorder.

Study underscores the need for more precise rare disease definitions

Some diseases are like black swans. They occur so rarely that many physicians never encounter them in their clinical practice, complicating efforts to treat them.

Certain enzymes implicated in diseases like cancer also destroy each other

Like motley bandits, certain enzymes implicated in cancer and other diseases also annihilate each other. A new study reveals details of their mutual foils in the hopes that these behaviors can be leveraged to fight the enzymes' disease potential.

Enzymes that cannibalize each other and promote cancer

A new study to be published this week in the journal The Proceedings of the National Academy of Sciences in the week of January 20, 2020. shows that certain human enzymes play dual roles in health and disease. Not only do they promote the occurrence of cancer and some other illnesses, they also eliminate one another rather like cannibals. The researchers hope this behaviour can be exploited to prevent these enzymes from causing human disease.

Effort to control opioids in an ER leaves some sickle cell patients in pain

India Hardy has lived with pain since she was a toddler — ranging from dull persistent aches to acute flare-ups that interrupt the flow of her normal life.

Fresh red blood cell transfusions are no more beneficial than older ones to critically ill children

A new study led by the Sainte-Justine University Hospital Centre and the University of Montreal, along with the Washington University School of Medicine in St. Louis, has found that transfusions using fresh red blood cells--cells that have spent seven days or less in storage--are no more beneficial than older red blood cells in reducing the risk of organ failure or death in critically ill children.

Identifying the type of pain in adults with sickle cell disease may help improve treatment

Identifying the type of pain an adult with sickle cell disease experiences may be useful in improving treatment, according to a new study by researchers at Yale Cancer Center and Smilow Cancer Hospital.

New tool can rapidly reveal unintended changes made by CRISPR-directed gene editing

Amidst rising hopes for using CRISPR gene editing tools to repair deadly mutations linked to conditions like cystic fibrosis and sickle cell disease, a new study in the Nature journal Communications Biology describes a new innovation that could accelerate this work by rapidly revealing unintended and potentially harmful changes introduced by a gene editing process.

Prenatal screening for hemoglobinopathies different in OBGYN practices and family medicine

Sickle cell disease is one of the most common inherited red blood cell disorders, yet many are not aware of their carrier status (Treadwell, J Nat Med Assoc, 2006), which can lead to confusion around pregnancy and newborn diagnosis.

Zebrafish study supports accuracy of CRISPR-Cas9 gene editing tool

Along with the promise that CRISPR-Cas9 gene editing technology can offer new human therapies is the need to ensure its safety. A recent study showed that CRISPR-Cas9 did not produce off-target gene mutations in zebrafish. These results, published in Frontiers in Genetics, confirm previous data in animal models that the risk to the rest of the genome from gene editing is minimal.

Mystery surrounds gene edited babies one year on

A year back Chinese scientist He Jiankui was in the news for all the wrong reasons. He had helped create the world’s first genetically edited human babies. After a year the world is still in dark about the whereabouts and health of the babies he had created and he himself has been not seen since January this year.

Carbon monoxide has a beneficial side at low concentrations

Most people think of carbon monoxide as harmful, and with good reason -- the colorless, odorless gas sends 50,000 people in the U.S. to hospitals each year when their furnaces malfunction or car engines run in poorly ventilated spaces. But at low concentrations, carbon monoxide has a beneficial side that scientists are trying to harness to treat diseases, according to an article in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society.
