Positive Doping Test Linked to Crumb Rubber From Artificial Football Pitch: Case Report

Drug Testing and Analysis, Volume 18, Issue 6, Page 719-724, June 2026.
1,3‐DMBA was detected in urine samples of eight athletes following a doping control, resulting in one AAF and levels below WADA's MRL in seven teammates. Investigation revealed contamination from rubber infill used on the indoor artificial turf, with analysis confirming 1,3‐DMBA in the turf's crumb rubber originating from recycled tires.

Autosomal Dominant Erythrocytosis Caused by Non‐Renal Erythropoietin (EPO) Due to EPO c.‐136 G>A Germline Mutation

American Journal of Hematology, Volume 101, Issue 4, Page 784-793, April 2026.
A novel erythropoietin (EPO) promoter mutation (c.‐136 G>A) causes autosomal dominant erythrocytosis via non‐renal expression of EPO. ABSTRACT We previously reported a five‐generation kindred with autosomal dominant erythrocytosis associated with a novel germline promoter variant in the erythropoietin (EPO) gene (EPO c.‐136 G>A).

Investigations Into the Human Metabolism of Trestolone (7α‐Methyl‐19‐Nortestosterone)

Drug Testing and Analysis, Volume 18, Issue 3, Page 341-353, March 2026.
As the known metabolites of 7α‐methyl‐19‐nortestosterone (MENT), M1 and M2, suffer from chromatographic issues under routine doping control conditions, the human metabolism of MENT was reinvestigated. From the numerous new metabolites detected, especially, M5 and M10 were identified as the most promising candidates to be implemented into routine ...
