New HIV infections declined by 30 percent in southern African communities where health workers conducted house-to-house voluntary HIV testing, referred people who tested positive to begin HIV treatment according to local guidelines, and offered other proven HIV prevention measures to those who tested negative. Local guidelines evolved during the study from offering HIV treatment based on immune health to offering immediate treatment for all.

A small pilot clinical study at the National Eye Institute (NEI) suggests that the drug nitisinone increases melanin production in some people with oculocutaneous albinism type 1B (OCA-1B), a rare genetic disease that causes pale skin and hair and poor vision. Increased melanin could help protect people with the condition against the sun’s UV rays and promote the development of normal vision. Study results were published in JCI Insight. NEI is part of the National Institutes of Health (NIH).

Researchers find genetic vulnerability to menthol cigarette use

A genetic variant found only in people of African descent significantly increases a smoker’s preference for cigarettes containing menthol, a flavor additive. The variant of the MRGPRX4 gene is five to eight times more frequent among smokers who use menthol cigarettes than other smokers, according to an international group of researchers supported by the U.S. Food and Drug Administration and the National Institutes of Health. The multiethnic study is the first to look across all genes to identify genetic vulnerability to menthol cigarettes. The paper was published online in the journal PLOS Genetics(link is external) on Feb. 15.

The first large-scale clinical trial to study liver transplantation between people with HIV has begun at clinical centers across the United States. The HOPE in Action Multicenter Liver Study will determine the safety of this practice by evaluating liver recipients for potential transplant-related and HIV-related complications following surgery. The study is sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and follows the 2018 launch of a similar study evaluating kidney transplantation between people with HIV.

National Eye Institute scientists led a collaborative study and zeroed in on genes associated with age-related macular degeneration (AMD), a leading cause of vision loss and blindness among people age 65 and older. These findings provide a more expanded and in-depth picture of the genetic contributions to AMD, and they present new pathways for treatment development. The study was published Feb. 11 in Nature Genetics.

Study links psoriasis treatment and improvement in heart artery disease

Researchers have found that treating psoriasis, a chronic inflammatory skin disease, with biologic drugs that target immune system activity can reduce the early plaque buildup that clogs arteries, restricts blood flow, and leads to heart attacks and stroke. The findings highlight how immunotherapies that treat inflammatory conditions might play a role in the reduction of cardiovascular disease risks. The study, funded by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health, appears online today in the journal Cardiovascular Research.

EMA’s human medicines committee (CHMP) has recommended for the first time an adjunct treatment to insulin in the form of a tablet for certain patients with type 1 diabetes mellitus.

Some gut cells slow down metabolism, accelerate cardiovascular disease: Study

Researchers have discovered how specific cells in the guts of mice slow down metabolism and eventually contribute to obesity, diabetes, hypertension and atherosclerosis. The findings, scientists say, could have important implications for the prevention and treatment of these kinds of metabolic diseases in humans. The study was funded by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health and appears in the journal Nature.

The future of minority health and health disparities research is here: NIH

  • By: Shalini.Sharma

Health disparities have persisted, despite extensive research and a decades-long mandate to eliminate them. Thus, the National Institute on Minority Health and Health Disparities (NIMHD) led a National Institutes of Health-wide, two-year science visioning process to chart a new research course to improve minority health and reduce health disparities. The American Journal of Public Health (AJPH) special issue  New Perspectives to Advance Minority Health and Health Disparities Research, is the culmination of this process with input from experts to help NIH determine the science needed to address health disparities. Thirty specific research strategies were identified across the three pillars that guided the science visioning: methods and measurement, etiology, and interventions.
