Much of what scientists know about how genetic differences affect health comes from studying populations outside Africa. This matters because genetic information is increasingly being used to understand disease, interpret genetic tests and, in some cases, guide treatment.
Africa has the greatest human genetic diversity in the world, yet African populations remain poorly represented in global genomic research. A genome is the complete set of DNA carried by a person. Only about 0.15% of participants in genome-wide association studies, which look for links between genetic differences and disease, are from Africa. When most of the evidence comes from populations elsewhere, some findings can be harder to interpret for African patients.

Continuous glucose monitors help type 2 diabetes patients spend 5 more hours a day in healthy blood sugar range - Medical Xpress
Continuous glucose monitors (CGMs) could transform diabetes management for millions of Americans with type 2 diabetes who don't take insulin, according to findings published in the New England Journal of Medicine. The clinical trial found that adults using CGMs spent approximately five additional hours each day within their target blood sugar range compared with those receiving routine care. Nearly twice as many CGM users also achieved an A1c level below 7%, a common treatment goal for people with diabetes.

“Beyond Detecting Cancer Recurrence: Can Whole-Genome Sequencing-Based ctDNA Monitoring Help Personalize Adjuvant Treatment? An exciting new study published in The Oncologist highlights the clinical potential of Signatera Genome, a whole-genome sequencing (WGS)-based, tumor-informed circulating tumor DNA (ctDNA) assay, not only for detecting molecular residual disease (MRD), but also for potentially informing adjuvant treatment decisions.
