A newly published literature review sheds light on how nuclear medicine brain imaging can help evaluate the biological changes that cause chemotherapy-related cognitive impairment (CRCI), commonly known as chemo-brain. Armed with this information, patients can understand better the changes in their cognitive status during and after treatment.

To develop treatments that may one day entirely rid the body of HIV infection, scientists have long sought to identify all of the places that the virus can hide its genetic code. Now, in a study using blood samples from men and women with HIV on long-term suppressive therapy, a team of scientists reports new evidence that one such stable reservoir of HIV genomes can be found in circulating white blood cells called monocytes.

While the donor cells in a bone marrow transplant can help cure the patient's blood cancer, they can also cause graft-versus-host disease -- in which donor T cells, a specialized immune cell in the blood, attack the patient's healthy cells. Before this study, there was no finite T cell population identified as the cause of GVHD. Now, researchers have identified the specific type of T cells that cause GVHD in immunodeficient mice. To further confirm their findings, the researchers directly investigated human patient samples.

Your circadian rhythm doesn't just govern your sleeping schedule; it can also impact cancer development, diagnosis, and treatment. Researchers discuss the role of circadian rhythms in tumor progression and spread and describe how we could better time when patients are tested for cancer and when they receive therapies to improve diagnostic accuracy and improve treatment success.

Putting less sugar in sodas and reducing the package size of sodas sold in supermarkets may help reduce our collective sugar intake and thus lower the associated health risks. Good news for consumers, but how does it affect manufacturers? Research conducted in the US has shown that marketing diet or sugar-free varieties does not lead to an increase in the overall turnover of soda manufacturers. This is because consumers tend to switch from sugary to sugar-free versions of the same brand. However, reducing the package size of soda does have a positive effect on the sales figures of the brand as a whole.
