University of Arizona researchers have identified a network of neurons that coordinate with other brain regions to influence eating behaviors. These findings could help those suffering from disease-induced appetite loss or over-eating.
Researchers from Aarhus University and Aarhus University Hospital have succeeded in using mice with a transplanted human immune system to study functions in the immune system which are otherwise particularly difficult to study. The method could turn out to be important in further research into e.g. cancer, HIV and autoimmune diseases.
Researchers at The Westmead Institute for Medical Research have discovered brand new immune cells that are at the frontline of HIV infection. Known as CD11c+ dendritic cells, these new cells are more susceptible to HIV infection and can then transmit the virus to other cells.
A new International Journal of Cancer study indicates that rates of invasive cervical cancer (ICC) are particularly high in women living with HIV in South Africa or Latin America.
Nurse practitioners are more likely to conduct HIV screenings if they feel that their colleagues support routine screenings, according to new research from Binghamton University, State University of New York. This comes in advance of National HIV Testing Day, taking place June 27, 2019.
A randomised trial of more than 7,800 African women found that a type of contraceptive injection (intramuscular depot medroxyprogesterone acetate -- DMPA-IM) posed no substantially increased risk of HIV acquisition when compared with a copper intrauterine device (IUD) and a levonorgestrel (LNG) implant. The results of this first ever randomised trial in the area, published in The Lancet, counter 30 years of epidemiology research suggesting a potential association between some types of contraceptives and risk of acquiring HIV.
Duke researchers describe a previously unidentified route for antibodies to be transferred from the mother to the fetus, illuminating a potential way to capitalize on this process to control when and how certain antibodies are shared.
A new study in JNCI Cancer Spectrum finds that dramatic increases in cancer survival in adolescents and young adults are undermined by continuing disparities by race, ethnicity, and socioeconomic status. The patterns here suggest that most of the recent survival increases in this age group were driven by improvements in treatments for HIV/AIDS and related cancers.
The US Preventive Services Task Force (USPSTF) recommends screening for HIV infection in adolescents and adults ages 15 to 65; in those younger or older at increased risk of infection; and in all pregnant people. The USPSTF routinely makes recommendations about the effectiveness of preventive care services and this statement is an update of its 2013 recommendation.
In a new recommendation, the US Preventive Services Task Force (USPSTF) recommends clinicians offer preexposure prophylaxis (PrEP) with effective antiretroviral therapy to people at high risk of acquiring HIV to decrease their risk of infection with the virus that causes AIDS.
