Objective: To compare the distribution of congenital anomalies within the VACTERL association (vertebral defects, anal atresia, cardiac, tracheoesophageal, renal, and limb abnormalities) between patients exposed to tumor necrosis factor-α (TNF-α) antagonist and the general population.

Methods: Analysis for comparison of proportional differences to a previous publication between anomaly subgroups, according to subgroup definitions of the European Surveillance of Congenital Anomalies (EUROCAT), a population-based database.

Results: Most EUROCAT subgroups belonging to the VACTERL association contained only one or 2 records of TNF-α antagonist exposure, so comparison of proportions was imprecise. Only the category "limb abnormalities" showed a significantly higher proportion in the general population.

Conclusion: The high number of congenital anomalies belonging to the VACTERL association from a report of pregnancies exposed to TNF-α antagonists could not be confirmed using a population-based congenital anomaly database.

TBC1D20 coordinates vesicle transport and actin remodeling to regulate ciliogenesis.

J Cell Biol

April 2025

Department of Genetics and Cell Biology, College of Life Sciences, State Key Laboratory of Medicinal Chemical Biology, Nankai University, Tianjin, China.

TBC1D20 deficiency causes Warburg Micro Syndrome in humans, characterized by multiple eye abnormalities, severe intellectual disability, and abnormal sexual development, but the molecular mechanisms remain unknown. Here, we identify TBC1D20 as a novel Rab11 GTPase-activating protein that coordinates vesicle transport and actin remodeling to regulate ciliogenesis. Depletion of TBC1D20 promotes Rab11 vesicle accumulation and actin deconstruction around the centrosome, facilitating the initiation of ciliogenesis even in cycling cells.

Impact of Hepatoblastoma on Infectious Complications Following Pediatric Liver Transplantation.

Pediatr Transplant

February 2025

Division of Infectious Diseases, Cincinnati Children's Hospital Medical Center, University of Cincinnati, Cincinnati, Ohio, USA.

Background: Liver transplantation is the standard therapy for end-stage liver disease in pediatric patients with biliary atresia (BA), congenital and metabolic conditions, and for an unresectable malignant tumor like hepatoblastoma (HB). BA is the leading indication for pediatric liver transplantation, while HB is the most common childhood liver cancer. Despite improved outcomes through advanced surgical techniques and novel immunosuppression, pediatric liver transplantation (pLT) is complicated by post-transplant infections.

Summary: Short stature is a common complaint among pediatric visits and the differential diagnosis is extensive. Although some variations in growth are normal, deviation from normal growth is often the first symptom of chronic disease in children. This is true for hormone abnormalities including growth hormone deficiency, hypothyroidism and glucocorticoid excess.
