Clear cell and papillary renal cell carcinomas in hereditary papillary renal cell carcinoma (HPRCC) syndrome: a case report

Hereditary papillary renal cell carcinoma

Hereditary papillary renal cell carcinoma (HPRCC) is an autosomal dominant syndrome characterized by the occurrence of bilateral and multifocal, classic type papillary renal cell carcinomas. In the recent decades, extensive molecular studies have narrowed the molecular underpinnings of this syndrome to missense mutations in tyrosine kinase domain of MET proto-oncogene. Although MET mutations are specific to HPRCC, it has been found in sporadic papillary renal cell carcinomas and as recently reported, in biphasic squamoid alveolar variant of papillary renal cell carcinoma. Dual MET/VEGFR2 kinase inhibitor and tyrosine kinase inhibitors have shown promising results in systemic therapy for HPRCC.

Predicting COVID-19 prognosis in hospitalized patients based on early status

IMPORTANCE

COVID-19 remains the fourth leading cause of death in the United States. Predicting COVID-19 patient prognosis is essential to help efficiently allocate resources, including ventilators and intensive care unit beds, particularly when hospital systems are strained. Our PLABAC and PRABLE models are unique because they accurately assess a COVID-19 patient's risk of death from only age and five commonly ordered laboratory tests. This simple design is important because it allows these models to be used by clinicians to rapidly assess a patient's risk of decompensation and serve as a real-time aid when discussing difficult, life-altering decisions for patients. Our models have also shown generalizability to external populations across the United States. In short, these models are practical, efficient tools to assess and communicate COVID-19 prognosis.
