    Data associated with the publication “Sex Hormones and Change in N-Terminal Pro-B-Type Natriuretic Peptide Levels: The Multi-Ethnic Study of Atherosclerosis”

    No full text
    Sex hormones are thought to be involved in sex differences in cardiovascular disease (CVD). N-terminal pro-B type natriuretic peptide (NT-proBNP) is a strong predictor of CVD. NT-proBNP levels are higher in women than men, which may relate to sex hormones. We analyzed cross-sectional and longitudinal associations between sex hormones and NT-proBNP levels in 2,371 postmenopausal women and 2,688 men in MESA. We found that a more androgenic pattern of sex hormones was associated with lower NT-proBNP levels among women and men cross-sectionally, which may contribute to sex differences in NT-proBNP levels. However, in longitudinal analyses, a more androgenic pattern of sex hormones was associated with a greater change in NT-proBNP levels in women and may reflect a mechanism for increased CVD risk in women after menopause. This data collection includes the supplemental tables associated with our publication

    Data associated with the PLoS ONE publications 'A Brief Intervention for Preparing ICU Families to be Proxies: A Phase I Study' and 'More than one in three proxies do not know their loved one’s current code status: An Observational Study in a Maryland ICU'

    Rationale: The majority of ICU patients lack decision-making capacity at some point during their ICU stay. However the extent to which proxy decision-makers are engaged in decisions about their patient’s care is challenging to quantify. Objectives: To assess 1) whether proxies know their patient’s actual code status as recorded in the electronic medical record (EMR), and 2) whether code status orders reflect ICU patient preferences as reported by proxy decision-makers. Methods: We interviewed proxy decision-makers for 111 consecutively admitted adult ICU patients. Proxies were asked about the patient’s goals of care, preferred code status, and actual code status. Responses were compared to code status orders in the EMR at the time of interview. Characteristics of patients and proxies who correctly vs incorrectly identified actual code status were compared, as were characteristics of proxies who reported a preferred code status that did vs did not match actual code status. Measurements and Main Results: A total of 42 proxies (36%) were incorrect or unsure about the patient’s actual code status and those who were correct vs. incorrect or unsure were similar in age, race, and years of education (P>0.20 for all comparisons). Thirty-five proxies (29%) reported a preferred code status that did not match the patient’s code status in the EMR. Matching preferred and actual code status was not associated with a patient’s age, gender, income, admission diagnosis, or subsequent in-hospital mortality or with proxy age, gender, race, education level, or relation to the patient (P>0.20 for all comparisons). Conclusions: More than 1 in 3 proxies is incorrect or unsure about their patient’s actual code status and more than 1 in 4 proxies reported that a preferred code status that did not match orders in the EMR. Proxy age, race, gender and education level were not associated with understanding or code status concordance

    Universal vs. Conditional 3-day follow up visit for children with unclassified fever at the community level: a cluster-randomized, community-based non-inferiority trial in Kalemie, Democratic Republic of Congo

    No full text
    Our group conducted a community-based non-inferiority trial in rural Democratic Republic of Congo to examine whether or not simplified approaches to following up children with uncomplicated fever would result in similar clinical failure rates as currently recommended more intensive follow up regimens. Between 2014 and 2016, we enrolled >4,000 children with uncomplicated fever from 28 communities in and around Kalemie, DRC. Eligible children were enrolled, provided either the current recommended universal follow-up advice (i.e. all return to CHW regardless of progression of illness) or the proposed simpler conditional follow-up advice (i.e. return to CHW only if illness continues or worsens). The primary outcome of the study was clinical failure, based on a range of clinical criteria assessed by CHWs at a home-based visit 7 days after enrollmen

    Data associated with the publication "Concretely Annotated Corpora"

    No full text
    Under the heading Concretely Annotated, we are processing a variety of standard corpora with multiple popular NLP tool-chains, collected together under a single data schema we have created that we refer to as CONCRETE. We envision a multimodal workflow, where, e.g., knowledge can be extracted from both text and audio. We developed CONCRETE to record and share annotations on structured human language data – both text and speech

    Data and software associated with publication "High-resolution behavioral mapping of electric fishes in Amazonian habitats"

    No full text
    This project includes datasets with recordings of weakly electric fish Eigenmannia virescens using grids of spatially distributed electrodes. These were collected in the LIMBS laboratory at JHU in 2014, and at the Terra Ronca cave in Brazil in 2016. The project also includes code for (1) analyzing the overhead images or video and extracting fish locations, (2) implementing the algorithms described in the publication for estimating fish positions and orientations using electrode measurements alone, and (3) reproducing the result figures from the publication that show the efficacy of electrode-based tracking as compared to video-based tracking

    Raw spectroscopic data from Californian rocks associated with the article 'Metamorphic records of multiple seismic cycles during subduction'

    No full text
    Large earthquakes occur in rocks undergoing high pressure/low temperature metamorphism during subduction. Rhythmic major-element zoning in garnet is a common product of such metamorphism, and one that must record a fundamental subduction process. Here we show that rhythmic major-element zoning in subduction-zone garnets from the Franciscan Complex, California developed in response to growth–dissolution cycles driven by pressure pulses. Using electron probe microanalysis and novel techniques in Raman and synchrotron Fourier transform infrared microspectroscopy, we demonstrate that at least four such pressure pulses, of magnitude 100–350 MPa, occurred over less than 300,000 years. These pressure magnitude and time scale constraints are most consistent with the garnet zoning having resulted from periodic overpressure development–dissipation cycles, related to pore-fluid pressure fluctuations linked to earthquake cycles. This study demonstrates that some metamorphic reactions can track individual earthquake cycles, and thereby opens new avenues to the study of seismicity

    Data and software associated with Seviour et al. 2017, The Stability of Mars’ Annular Polar Vortex

    No full text
    The Martian polar atmosphere is known to have a persistent local minimum in potential vorticity (PV) near the winter pole, with a region of high PV encircling it. This finding is surprising since an isolated band of PV is barotropically unstable, a result going back to Rayleigh. Here we investigate the stability of a Mars-like annular vortex using numerical integrations of the rotating shallow water equations. We show how the mode of instability and its growth rate depends upon the latitude and width of the annulus. By introducing thermal relaxation towards an annular equilibrium profile with a time scale similar to that of the instability, we are able to simulate a persistent annular vortex with similar characteristics as that observed in the Martian atmosphere. This time scale, typically 0.5-2 sols, is similar to radiative relaxation time scales for Mars’ polar atmosphere. We also demonstrate that the persistence of an annular vortex is robust to topographic forcing, as long as it is below a certain amplitude. We hence propose that the persistence of this barotropically unstable annular vortex is permitted due to the combination of short radiative relaxation time scales and relatively weak topographic forcing in the Martian polar atmosphere

    Current-voltage raw data and spectra for thiophene polymer characterization and sensing responses

    This dataset is backup information for the publication whose abstract is reproduced here. NO2-responsive polymer-based organic field-effect transistors (OFETs) are described and room-temperature detection with high sensitivity entirely from the semiconductor was achieved. Two thiophene polymers, poly(bisdodecylquaterthiophene) and poly(bisdodecylthioquaterthiophene) (PQT12 and PQTS12, respectively), were used as active layers to detect a concentration at least as low as 1 ppm NO2. The proportional on-current change of OFETs using these polymers reached over 400% for PQTS12, which is among the highest sensitivities reported for an NO2-responsive device based on an organic semiconducting film. From measurements of cyclic voltammetry and the electronic characteristics, we found that the introduction of sulfurs into the side chains induces traps in films of the PQTS12 and also decreases domain sizes, both of which could contribute to the higher sensitivity of PQTS12 to NO2 gas compared to PQT12. The ratio of responses of PQTS12 and PQT12 is higher for exposures to lower concentrations, making this parameter a means of distinguishing responses to low concentrations for extended times from exposures to high concentrations from shorter times. The responses to nonoxidizing vapors were much lower indicating good selectivity to NO2 of two polymers. This work demonstrates the capability of increasing selectivity and calibration of OFET sensors by modulating redox and aggregation properties of polymer semiconductors
