The SARS-CoV-2 Delta variant rose to dominance in mid-2021, likely propelled by an estimated 40%–80% increased transmissibility over Alpha. To investigate if this ostensible difference is uniform across populations, we partner with public health programs from all six states New England the United States. We compare logistic growth rates during each variant's respective emergence period, finding that emerged 1.37–2.63 times faster than Alpha (range states). compute variant-specific effective...

Imatinib, selective tyrosine kinase inhibitor, has been beneficial adjuvant therapy in patients unresectable, recurrent, or metastatic DFSP. Because of its characteristic infiltrative growth, effective surgical excision DFSP may be limited by the disfigurement functional impairment. In recent cases, neoadjuvant imatinib...
