Data from: Linking the vectorial capacity of multiple vectors to observed patterns of West Nile virus transmission
1. Theoretical models suggest that increased vector species participation in pathogen transmission significantly increases the prevalence of vector and host infections. However, there has been a lack of empirical evidence to support this. 2. We linked transmission potential of multiple vectors species to observed patterns of enzootic pathogen transmission by conducting longitudinal field surveillance of West Nile virus (WNv) infections in Culex spp. mosquitoes and avian host communities in the southeastern U.S. We then used a temperature-dependent vectorial capacity model as a predictor of WNv infections in mosquitoes and birds using general linear mixed effects models. 3. Two WNv-competent Culex spp. mosquitoes were present in our study sites, Culex restuans Theobald during the spring and Culex quinquefasciatus Say during the summer. Empirical evidence of WNv transmission was limited exclusively to time periods when night time temperatures were suitable for accelerated within-vector viral replication, susceptible avian hosts (i.e. hatch year birds) were abundant, and Culex quinquefasciatus was the primary Culex spp. vector in the mosquito community. 4. Contrary to theoretical predictions, increased presence of competent vector species through time did not significantly increase the prevalence of infections in the WNv enzootic system. 5. Synthesis and applications. We extend a commonly used theoretical framework to quantify transmission potential of vector-borne diseases, the vectorial capacity equation, to account for species-specific variations in temperature-dependent development and host feeding preference. By quantifying key vectorial capacity parameters using field data from southeast United States we quantified the relative contribution of two Culex spp. species (Culex pipiens quinquefasciatus and Culex restuans) to the transmission of West Nile virus (WNv). Our findings suggest that to reduce the risk of human exposure to WNv in urban environments, vector control should focus on the primary WNv vector, the members of the Culex pipiens complex. Additionally, vector control may be more effective if it coincides with the onset of the avian breeding season, when most WNv amplification occurs. Moreover, our results highlight relevant knowledge gaps pertaining to WNv transmission by secondary mosquito species that coexist either in time or space with Culex pipiens complex mosquitoes. A better understanding of secondary WNv vector species is greatly needed in order to appropriately gauge their role in pathogen transmission dynamics.

Observations of flowering phenology in Concord, Massachusetts, USA, 1963-1993
<p>Phenology plays a vital role in understanding the impacts of climate change on plants. Observing and recording the dates that plants are in flower, over periods of years and decades, can elucidate patterns in how plants respond to warming temperatures, shifting precipitation regimes, and other effects of a changing climate. Long-term records of plant phenology are difficult to find. It is often the case that these records do not originate from scientific research studies but instead are the product of an individual's interest in observing natural phases in their local environment. Pennie Logemann (1918-2011) was a resident of Concord, Massachusetts, United States and a landscape designer. From 1963-1993 she recorded the flowering times of plants in her woodland garden, resulting in an invaluable dataset of wildflower and shrub phenology. These plants were primarily local native plants, but included some non-native species as well. Most likely her garden contained a mixture of species occurring naturally on her property and species planted deliberately.</p> <p>Logemann's records have been analyzed in compilation with observations made by Henry David Thoreau and contemporary researchers in a study of recent climate change in Concord. The dataset provided here includes flowering phenology records for 71 species over 30 years (discontinuous for most species) at a single location. We encourage the use of these data in further studies of plant phenology and hope they may provide encouragement for others to record and share their phenology data.</p>

The bradykinin-2 receptor antagonist, icatibant, improves lung function in patients with SARS-CoV2 associated ARDS - First results of a prospective off-label use patient-related observational study.
<p>SARS-CoV2-associated adult respiratory distress syndrome (COVID19-ARDS) frequently leads to fatal respiratory failure in COVID19. Currently, there is no curative treatment option for severe COVID19-ARDS other than mechanical ventilation therapy and extracorporal membrane oxygenation (ECMO). We investigated whether modification of the kallikrein-kinin system in vivo attenuates the progression of SARS-CoV2-induced ARDS. The aim of the study was to investigate the effect of blockade of the B2R on the course of COVID19-ARDS. In an observational study including 53 COVID19-ARDS patients, patients received the bradykinin-2-receptor antagonist (B2RAg) icatibant. After icatibant substitution, respiratory rate in COVID19-ARDS reduced by a maximum of 32% (24.9/min to 16.8/min) with a concomitant reduction in oxygen substitution by 59% (6.1 LO<sub>2</sub>/min to 2.5 LO<sub>2</sub>/min). The data show that the use of icatibant in the early phase of COVID19-ARDS is suitable to stabilize pulmonary gas exchange. Furthermore, early icatibant substitution seems to be able to reduce the rate of necessary invasive ventilation in COVID19-ARDS. Observational data suggest that inhibition of bradykinin signalling leads to stabilization of lung function in SARS-CoV2-associated ARDS. Further prospective placebo-controlled studies are needed to investigate the impact of the kallikrein-kinin system on the development of COVID19-ARDS in vivo.</p>
