Congenital and Infantile Masses of the Head and Neck.

The spectrum of congenital and infantile masses of the head and neck is broad, including developmental and neoplastic entities. The diseases encountered in this vulnerable patient population differ substantially from those in older children and adults. Familiarity with the types of encountered masses, typical imaging characteristics, and expected clinical course is critical for radiologists who care for pregnant women (fetuses) and infants.

Racial/ethnic differences in tumor biology and treatment outcomes in women with ductal carcinoma in situ.

Background: Racial differences in invasive breast cancer exist, but less is known about ductal carcinoma in situ. Our aim was to assess racial/ethnic differences in ductal carcinoma in situ tumor biology and treatment.

Methods: Adults with ductal carcinoma in situ were identified from the National Cancer Database, 2012-2021.

Cerebral vascular shunting and oxygen metabolism in sickle cell disease.

Patients with sickle cell disease (SCD) are at elevated risk of silent cerebral infarcts and strokes; however, they frequently lack established stroke risk factors (e.g., macrovascular arterial steno-occlusion) and as such the mechanisms underlying such events are incompletely characterized.

Leveraging large-scale Mycobacterium tuberculosis whole genome sequence data to characterise drug-resistant mutations using machine learning and statistical approaches.

Tuberculosis disease (TB), caused by Mycobacterium tuberculosis (Mtb), is a major global public health problem, resulting in > 1 million deaths each year. Drug resistance (DR), including the multi-drug form (MDR-TB), is challenging control of the disease. Whilst many DR mutations in the Mtb genome are known, analysis of large datasets generated using whole genome sequencing (WGS) platforms can reveal new variants through the assessment of genotype-phenotype associations.
