Internal Medicine, East Africa

Here we developed and deployed the blended genome exome (BGE) method, a DNA library approach that generates low-pass whole-genome (1–4× mean depth) and deep whole-exome (30–40× mean depth) data in a single sequencing run. BGE is cost-effective, empowers most genomic discoveries possible with deep whole-genome sequencing and captures global common single-nucleotide polymorphism diversity. We applied BGE to sequence >53,000 samples from the PUMAS Project (Populations Underrepresented in Mental Illness Associations Studies), including African, African American and Latin American populations. Imputed genotypes showed high concordance with Illumina Global Screening Array calls (R2 ≥ 95% for minor allele frequency ≥1%; …

A Puzzling Case Of Visual Disturbances Leads To A Fatal Neurodegenerative Diagnosis, Courtney J. Austin, Aaron Carrillo, Jennifer Rojas Huen, Victoria Parada

Research Colloquium

Background: Creutzfeldt-Jakob disease (CJD) is a rare neurodegenerative disease in which early diagnosis is complicated by the presence of early non-specific and atypical presentations. Sporadic CJD (sCJD), the most common type of CJD, is caused by the spread of a disease-forming prion known as PrPSc. PrPSc multiplies and binds to the normal form of prion, or PrP, converting it to an abnormal, structurally altered disease form that spreads throughout the brain. sCJD can initially present with six different phenotypes: cognitive, affective, classic, visual (Heidenhain variant), atactic (Oppenheimer-Brownell variant), and indeterminate. The classic presentation of CJD includes rapidly progressive dementia with …

Several clinical and experimental studies have demonstrated that traumatic brain injury (TBI) activates cascades of biochemical, molecular, structural, and pathological changes in the brain. These changes combine to contribute to the various outcomes observed after TBI. Given the breadth and complexity of changes, combination treatments may be an effective approach for targeting multiple detrimental pathways to yield meaningful improvements. In order to identify targets for therapy development, the temporally evolving pathophysiology of TBI needs to be elucidated in detail at both the cellular and molecular levels, as it has been shown that the mechanisms contributing to cognitive dysfunction change over …

Importance: Recent large infarct thrombectomy trials used heterogeneous imaging modalities and time windows for patient selection. Noncontrast computed tomographic (CT) scan is the most common stroke imaging approach. It remains uncertain whether thrombectomy is effective for patients with large infarcts identified using noncontrast CT alone within 24 hours of stroke onset.

Objective: To evaluate the effect of thrombectomy in patients with a large infarct on a noncontrast CT scan within 24 hours of onset.

Design, setting, and participants: Open-label, blinded-end point, bayesian-adaptive randomized trial with interim analyses for early stopping (futility or success) or population enrichment, which was conducted at …
