Strontium isoscape of sub-Saharan Africa allows tracing origins of victims of the transatlantic slave trade.

Strontium isotope (Sr/Sr) analysis with reference to strontium isotope landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, and forensics. However, despite the vast potential of research involving Sr/Sr analysis particularly in Africa, Sr isoscapes remain unavailable for the largest parts of the continent. Here, we measure the Sr/Sr ratios in 778 environmental samples from 24 African countries and combine this data with published data to model a bioavailable Sr isoscape for sub-Saharan Africa using random forest regression.

Germline de novo alterations of RUNX1T1 in individuals with neurodevelopmental and congenital anomalies.

Runt-related transcription factor 1 translocated to 1 (RUNX1T1; also known as eight-twenty-one [ETO]) encodes a transcription regulator for hematopoietic genes and is well known for its involvement in hematologic malignancies, particularly acute myeloid leukemia (AML). However, its role in congenital disease is less understood. This study provides detailed clinical and molecular information on three cases exhibiting neurodevelopmental and congenital anomalies with germline de novo alterations in RUNX1T1.

Strengthening the Chain: A Continuing Medical Education Program for Test Results Follow-up.

Introduction: The Canadian Medical Protective Association (CMPA)'s Commitment to Change in Test-Results Follow-Up (CTC-TRFU) program aims to provide physicians with resources to enhance their test results follow-up systems for improved patient safety. Framed around the Transtheoretical Model, the program involves a 6-month multimodal educational intervention involving individual and group coaching sessions, action planning, and reflection surveys.

Methods: This study evaluates the CTC-TRFU program's impact by analyzing survey responses and course documents, focusing on three main outcomes: physicians' perceived barriers and challenges, changes in their confidence and commitment, and implemented practice changes with perceived impact on patient safety.

Association between the A316T Mutation and Adolescent Idiopathic Scoliosis in French Canadian and Italian Cohorts.

Studies have revealed anthropometric discrepancies in girls with adolescent idiopathic scoliosis (AIS) compared to non-scoliotic subjects, such as a higher stature, lower weight, and lower body mass index. While the causes are still unknown, it was proposed that metabolic hormones could play a role in AIS pathophysiology. Our objectives were to evaluate the association of A316T polymorphism in AIS susceptibility and to study its relationship with disease severity and progression.
