Sex differences in IV thrombolysis treatment for stroke: a systematic review and meta-analysis

Brent Strong, Lynda Lisabeth & Mathew Reeves
Objective: A prior meta-analysis of reports published between 2000 and 2008 found that women were 30% less likely to receive IV rt-PA treatment for stroke than men; we updated this meta-analysis to determine if this sex difference still persisted. Methods: We identified studies that reported sex-specific IV rt-PA treatment rates for acute ischemic stroke published between 2008 and 2018. Eligible studies included representative populations of ischemic stroke patients from hospital-based, registry-based, or administrative data. Random...

TypeTE: a tool to genotype mobile element insertions from whole genome resequencing data

Clément Goubert, Jainy Thomas, Lindsay Payer, Jeffrey Kidd, Julie Feusier, W. Scott Watkins, Kathleen Burns, Lynn Jorde & Cédric Feschotte
Alu retrotransposons account for more than 10% of the human genome, and insertions of these elements create structural variants segregating in human populations. Such polymorphic Alu are powerful markers to understand population structure, and they represent variants that can greatly impact genome function, including gene expression. Accurate genotyping of Alu and other mobile elements has been challenging. Indeed, we found that Alu genotypes previously called for the 1000 Genomes Project are sometimes erroneous, which poses...

Data from: Deconstructing an infamous extinction crisis: Survival of Partula species on Moorea and Tahiti

Amanda Haponski, Taehwan Lee & Diarmaid O' Foighil
Eleven of eighteen Society Island Partula species endemic to the Windward Island subgroup (Moorea and Tahiti) have been extirpated by an ill-advised biological control program. The conservation status of this critically endangered tree snail radiation is of considerable import, but is clouded by taxonomic uncertainty due to the extensive lack of congruence among species designations, diagnostic morphologies and molecular markers. Using a combination of museum, captive, and remnant wild snails, we obtained the first high-resolution...

Data from: Functional traits, not productivity, predict openness to seedling recruitment in alpine plant communities under climatic warming

Eric Meineri, Kari Klanderud, John Guittar, Deborah Goldberg & Vigdis Vandvik
Understanding the degree to which plant communities are open to seedling recruitment is key to predicting how they will be impacted by climate change. We experimentally assessed whether communities assembled under colder climates were inherently more open to recruitment than warmer-climate communities, after controlling for differences in the current climate under which the communities were growing. We then tested whether variation in openness to recruitment could be explained by community biomass or by the plant...

Data from: Long-term dynamics of liana seedlings suggest decelerating increases in liana relative abundance over time

Maria Natalia Umaña, Eric Manzané-Pinzón & Liza Comita
Over the past decades, tropical forests have experienced both compositional and structural changes. In the Neotropics, researchers at multiple sites have observed significant increases in the abundance and biomass of lianas (i.e. woody vines) relative to trees. However, the role of dynamics at early life stages in contributing to increasing liana abundance remains unclear. We took advantage of a unique dataset on seedling dynamics over 16 years in ~20,000 1-m2plots in a tropical forest in...

Data from: The contribution of host cell-directed vs. parasite-directed immunity to the disease and dynamics of malaria infections

Nina Wale, Matthew J. Jones, Derek G. Sim, Andrew F. Read & Aaron A. King
Hosts defend themselves against pathogens by mounting an immune response. Fully understanding the immune response as a driver of host disease and pathogen evolution requires a quantitative account of its impact on parasite population dynamics. Here, we use a data-driven modeling approach to quantify the birth and death processes underlying the dynamics of infections of the rodent malaria parasite, Plasmodium chabaudi, and the red blood cells (RBCs) it targets. We decompose the immune response into...

Similar but different: Revealing the relative roles of species‐traits versus biome properties structuring genetic variation in South American marsh rats

Joyce Rodrigues Do Prado, Joyce R. Prado, Alexandre R. Percequillo, Andréa T. Thomaz & L. Lacey Knowles
Aim: Wetland habitats, and the ecological restrictions imposed by them, structure patterns of genetic variation in constituent taxa. As such, genetic variation may reflect properties of the specific biomes species inhabit, or shared life history traits among species may result in similar genetic structure. We evaluated these hypotheses jointly by quantifying the similarity of genetic structure in three South American marsh rat species (Holochilus), and test how genetic variation in each species relates to biome‐specific...

Evaluating the boundaries of marine biogeographic regions of the Southwestern Atlantic using halacarid mites (Halacaridae), meiobenthic organisms with a low dispersal potential

Almir Pepato, Pavel Klimov & Teofânia Vidigal
Aim We evaluated traditional biogeographic boundaries of coastal marine regions in SW Atlantic using DNA sequence data from common, rocky-shore inhabiting, marine mites of the genera Agauopsis and Rhombognathus, family Halacaridae. Methods We investigated geographic population genetic structure using CO1 gene sequences, estimated divergence times using a multigene dataset and absolute time-calibrated molecular clock analyses, and performed environmental niche modeling (ENM) of common marine mite species. Results Agauopsis legionium has a shallow history (2.01 Ma)...

Data from: Physician champions’ perspectives and practices on electronic health records implementation: challenges and strategies

Xinning Gui, Yunan Chen, Xiaomu Zhou, Tera L. Reynolds, Kai Zheng & David A. Hanauer
Objective: Physician champions are “boots on the ground” physician leaders who facilitate the implementation of, and transition to, new health information technology (HIT) systems within an organization. They are commonly cited as key personnel in HIT implementations, yet little research has focused on their practices and perspectives. Methods: We addressed this research gap through a qualitative study of physician champions that aimed to capture their challenges and strategies during a large-scale HIT implementation. Email interviews...

Trophic-specific responses to migration in empirical metacommunities

Zachary Hajian-Forooshani
The metacommunity, as it evolved from Levins’s metapopulation, provides a framework to consider the spatial organization of species interactions. A defining feature of metapopulations and metacommunities is that organisms (populations or communities) are connected via migration. An important result from Levins’s metapopulation work—that increasing migration lowers regional extinction probability—is often incorporated into conceptions of metacommunities; however, this may not hold true for multiple interacting metapopulations (metacommunities). We report results from a metacommunity field experiment conducted...

Data from: Tip rates, phylogenies, and diversification: what are we estimating, and how good are the estimates?

Pascal O. Title & Daniel L. Rabosky
1. Species-specific diversification rates, or “tip rates”, can be computed quickly from phylogenies and are widely used to study diversification rate variation in relation to geography, ecology, and phenotypes. These tip rates provide a number of theoretical and practical advantages, such as the relaxation of assumptions of rate homogeneity in trait-dependent diversification studies. However, there is substantial confusion in the literature regarding whether these metrics estimate speciation or net diversification rates. Additionally, no study has...

Schwalb, David R. Smith, Alan D. Steinman & Jonathan M. Jeschke
Dreissenid mussels (including the zebra mussel Dreissena polymorpha and the quagga mussel D. rostriformis) are among the world's most notorious invasive species, with large and widespread ecological and economic effects. However, their long‐term population dynamics are poorly known, even though these dynamics are critical to determining impacts and effective management. We gathered and analyzed 67 long‐term (>10 yr) data sets on dreissenid populations from lakes and rivers across Europe and North America. We addressed five...

Buell, Brian Burkett, Yu Chen, Zijun Chen, Ben Chiaro, Roberto Collins, William Courtney, Andrew Dunsworth, Edward Farhi, Brooks Foxen, Austin Fowler, Craig Gidney, Marissa Giustina, Rob Graff … & Adam Zalcman
The tantalizing promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor. A fundamental challenge is to build a high-fidelity processor capable of running quantum algorithms in an exponentially large computational space. Here, we report using a processor with programmable superconducting qubits to create quantum states on 53 qubits, corresponding to a computational state-space of dimension 2^53 ∼ 10^16. Measurements from repeated...

Data from: Differential changes in bone strength of two inbred mouse strains following administration of a sclerostin-neutralizing antibody during growth

Noah J. Mathis, Emily N. Adaniya, Lauren M. Smith, Alexander G. Robling, Karl J. Jepsen & Stephen H. Schlecht
Administration of sclerostin-neutralizing antibody (Scl-Ab) treatment has been shown to elicit an anabolic bone response in growing and adult mice. Prior work characterized the response of individual mouse strains but did not establish whether the impact of Scl-Ab on whole bone strength would vary across different inbred mouse strains. Herein, we tested the hypothesis that two inbred mouse strains (A/J and C57BL/6J (B6)) will show different whole bone strength outcomes following sclerostin-neutralizing antibody (Scl-Ab) treatment...

Data from: Nocturnal flight-calling behaviour predicts vulnerability to artificial light in migratory birds

Benjamin M. Winger, Brian C. Weeks, Andrew Farnsworth, Andrew W. Jones, Mary Hennen & David E. Willard
Understanding interactions between biota and the built environment is increasingly important as human modification of the landscape expands in extent and intensity. For migratory birds, collisions with lighted structures are a major cause of mortality, but the mechanisms behind these collisions are poorly understood. Using 40 years of collision records of passerine birds, we investigated the importance of species’ behavioral ecologies in predicting rates of building collisions during nocturnal migration through Chicago, IL and Cleveland,...

Data from: Flexible gaze-following in rhesus monkeys

Rosemary Bettle & Alexandra G. Rosati
Humans are characterized by complex social cognitive abilities that emerge early in development. Comparative studies of nonhuman primates can illuminate the evolutionary history of these social capacities. We examined the cognitive skills that rhesus monkeys (Macaca mulatta) use to follow gaze, a foundational skill in human social development. While rhesus monkeys can make inferences about others’ gaze when competing, it is unclear how they think about gaze information in other contexts. In study 1, monkeys...

Data from: Heterochrony in chimpanzee and bonobo spatial memory development

Alexandra G. Rosati
Objectives: The emergence of human-unique cognitive abilities has been linked to our species' extended juvenile period. Comparisons of cognitive development across species can provide new insights into the evolutionary mechanisms shaping cognition. This study examined the development of different components of spatial memory, cognitive mechanisms that support complex foraging, by comparing two species with similar life history that vary in wild ecology: bonobos (Pan paniscus) and chimpanzees (Pan troglodytes). Materials and methods: Spatial memory development...
