Early thoracic surgery consultation and location of therapy impact time to esophagectomy.

Background: Neoadjuvant chemoradiation therapy (nCRT) followed by esophagectomy is the standard treatment for resectable, locally advanced esophageal cancer. The ideal timing between neoadjuvant therapy and esophagectomy is unclear. Delayed esophagectomy is associated with worse outcomes.

Early adoption of robotic lung resection in an established video assisted thoracic surgery practice.

Background: Reported advantages to robotic thoracic surgery include shorter length of stay (LOS), improved lymphadenectomy, and decreased complications. It is uncertain if these benefits occur when introducing robotics into a well-established video-assisted thoracoscopy (VATS) practice. We compared the two approaches to investigate these advantages.

Whole genome assembly and annotation of the King Angelfish () gives insight into the evolution of marine fishes of the Tropical Eastern Pacific.

angelfishes are some of the most iconic marine fishes of the Tropical Eastern Pacific (TEP). However, very limited genomic resources currently exist for the genus. In this study we: (i) assembled and annotated the nuclear genome of the King Angelfish (), and (ii) examined the demographic history of in the TEP.

Liposomal bupivacaine intercostal block placed under direct vision reduces morphine use in thoracic surgery.

Background: Thoracic epidural analgesia (TEA) and liposomal bupivacaine (LB) are two methods used for postoperative pain control after thoracic surgery. Some studies have compared LB to standard bupivacaine. However, data comparing the outcomes of LB to TEA after minimally invasive lung resection is limited.

Editorial overview: Novel approaches to gauge the human footprint on the biosphere.

Human disturbances are altering the biosphere in unprecedented ways. Yet, the precise picture of how these disturbances are altering the biosphere and the consequences for humans and the planet reamain undefined. The knowledge and tools to quantify these impacts are often dispersed across traditionally independent scientific disciplines.

Unraveling the complex phylogeographic history of freshwater fishes in Lower Central America: A study of the electric fish Brachyhypopomus occidentalis.

Lower Central America (LCA) has a complex biogeographic history shaped by the rise of the Isthmus of Panama and the global climatic oscillations of the Pleistocene. These events have been crucial in structuring biodiversity in LCA, but their consequences for the distribution and partitions of genetic diversity across the region remain to be elucidated. We combined complete mitochondrial genomes and nuclear ultraconserved elements (UCEs) to study the phylogeographic history and population genetic structure of the electric fish Brachyhypopomus occidentalis in LCA.

Biological invasions alter the structure of a tropical freshwater food web.

Biological invasions are expected to alter food web structure, but there are limited empirical data directly comparing invaded versus uninvaded food webs, particularly in species-rich, tropical systems. We characterize for the first time the food web of Lake Gatun-a diverse and highly invaded tropical freshwater lake within the Panama Canal. We used stable isotope analysis to reconstruct the trophic structure of the fish community of Lake Gatun and to compare it to that of a minimally invaded reference lake, Lake Bayano.

The fitness landscape of a community of Darwin's finches.

Divergent natural selection should lead to adaptive radiation-that is, the rapid evolution of phenotypic and ecological diversity originating from a single clade. The drivers of adaptive radiation have often been conceptualized through the concept of "adaptive landscapes," yet formal empirical estimates of adaptive landscapes for natural adaptive radiations have proven elusive. Here, we use a 17-year dataset of Darwin's ground finches (Geospiza spp.

Unraveling the genomic complexity of sylvatic mosquitoes in changing Neotropical environments.

Sylvatic New World mosquitoes (e.g. Old-growth Forest species) can transmit viruses among non-human primates.

Comparative phylogeography reveals widespread cryptic diversity driven by ecology in Panamanian birds.

Widespread species often harbor unrecognized genetic diversity, and investigating the factors associated with such cryptic variation can help us better understand the forces driving diversification. Here, we identify potential cryptic species based on a comprehensive dataset of COI mitochondrial DNA barcodes from 2,333 individual Panamanian birds across 429 species, representing 391 (59%) of the 659 resident landbird species of the country, as well as opportunistically sampled waterbirds. We complement this dataset with additional publicly available mitochondrial loci, such as ND2 and cytochrome obtained from whole mitochondrial genomes from 20 taxa.

Harnessing the omics revolution to address the global biodiversity crisis.

Human disturbances are altering global biodiversity in unprecedented ways. We identify three fundamental challenges underpinning our understanding of global biodiversity (namely discovery, loss, and preservation), and discuss how the omics revolution (e.g.

Exploring potential drivers of brain size variation in the electric fish Brachyhypopomus occidentalis.

Characterizing the factors that shape variation in brain size in natural populations is crucial to understanding the evolution of brain size in animals. Here, we explore how relative brain size and brain allometry vary with drainage, predation risk and sex in natural populations of the electric knifefish Brachyhypopomus occidentalis. Fish were sampled from high and low predation risk sites within two independent river drainages in eastern and central Panamá.

Moving past the challenges and misconceptions in urban adaptation research.

Although the field of urban evolutionary ecology has recently expanded, much progress has been made in identifying adaptations that arise as a result of selective pressures within these unique environments. However, as studies within urban environments have rapidly increased, researchers have recognized that there are challenges and opportunities in characterizing urban adaptation. Some of these challenges are a consequence of increased direct and indirect human influence, which compounds long-recognized issues with research on adaptive evolution more generally.

The terroir of the finch: How spatial and temporal variation shapes phenotypic traits in DARWIN'S finches.

The term is used in viticulture to emphasize how the biotic and abiotic characteristics of a local site influence grape physiology and thus the properties of wine. In ecology and evolution, such terroir (i.e.

Report on lung cancer surgery during COVID-19 pandemic at a high volume US institution.

Background: The impact of COVID-19 has been felt in every field of medicine. We sought to understand how lung cancer surgery was affected at a high volume institution. We hypothesized that patients would wait longer for surgery, have more advanced tumors, and experience more complications during the COVID-19 crisis.

Comparison of traditional and DNA metabarcoding samples for monitoring tropical soil arthropods (Formicidae, Collembola and Isoptera).

The soil fauna of the tropics remains one of the least known components of the biosphere. Long-term monitoring of this fauna is hampered by the lack of taxonomic expertise and funding. These obstacles may potentially be lifted with DNA metabarcoding.

Salvage surgery for local recurrence after sublobar surgery in Stages I and II non-small cell lung cancer.

Background And Objectives: To examine if patients undergoing salvage surgery for local recurrence following sublobar resection (SLR) have similar perioperative complications and overall survival (OS) compared to lobectomy patients for early stage non-small cell lung cancer (NSCLC).

Methods: Patients undergoing lobectomy and SLR (segmentectomy or wedge resection) for Stages I and II NSCLC from 2010 to 2016 were reviewed. Lobectomy patients and those who underwent salvage surgery for local recurrence after SLR were compared.
