A Complete Assembly and Annotation of the American Shad Genome Yields Insights into the Origins of Diadromy.

Transitions across ecological boundaries, such as those separating freshwater from the sea, are major drivers of phenotypic innovation and biodiversity. Despite their importance to evolutionary history, we know little about the mechanisms by which such transitions are accomplished. To help shed light on these mechanisms, we generated the first high-quality, near-complete assembly and annotation of the genome of the American shad (Alosa sapidissima), an ancestrally diadromous (migratory between salinities) fish in the order Clupeiformes of major cultural and historical significance.

The clinical significance of open vs. minimally invasive surgical approaches in the management of thymic epithelial tumors and myasthenia gravis.

Though advancements have been made in the pharmacologic treatment of myasthenia gravis (MG), surgical resection is not only an option as a last line of defense for those patients who do not respond to medical therapy but also remains vital for those with thymic epithelial tumors (TET). While prior studies have shown the potential superiority of minimally invasive approaches via robotic- and video-assisted thoracoscopic surgery (RATS/VATS) for thymectomy compared to open surgery, in the setting of malignancies, this outcome delineation is controversial. As RATS/VATS may be associated with less post-operative complications in the treatment of TET, some surgeons argue that the open approach is necessary for complete resection (R0 resection) and to prevent potential seeding of the malignancy.

Time to surgery in early-stage non-small cell lung cancer: Defining the optimal diagnosis-to-resection interval to reduce mortality.

Background: Most patient variables that impact cancer case complexity and outcomes are not modifiable preoperatively; however, the time from diagnosis to surgical resection is fluid. This retrospective study sought to identify the optimal interval from diagnosis of non-small cell lung cancer (NSCLC) to surgery to reduce mortality.

Methods: We evaluated adult patients with early-stage NSCLC who underwent upfront surgical resection between 2009 and 2019 using institutional data.

Evaluation of treatment strategies for patients with stage IIIA non-small cell lung cancer in the immunotherapy era.

Background: Optimal treatment for patients with stage IIIA NSCLC is controversial. Growing evidence indicates surgery with adjuvant or neoadjuvant chemotherapy (SC) may be superior to non-surgical treatments. Direct comparisons have not been performed between SC and chemoradiation with immunotherapy (CRI) among patients diagnosed with stage IIIA NSCLC since consolidation immunotherapy was added to treatment guidelines.
