Comparison of Care Patterns and Rehospitalizations for Mechanically Ventilated Patients in New York and Ontario
Rationale: Mechanically ventilated patients require complex care and are at high risk for rehospitalization, but different systems of care may result in different hospital discharge practices and rates of rehospitalization.
Objectives: To compare lengths of hospitalization, discharge patterns, and rehospitalization rates in New York (NY) in the US and Ontario (ON) in Canada.
Methods: We conducted a retrospective cohort study of mechanically ventilated patients who survived an acute care hospitalization in NY or ON from 2010-2012, using linkable administrative healthcare data.
Measurements and Main Results: The primary outcome was the cumulative incidence of first rehospitalization within 30 days of discharge, accounting for the competing risk of death. Of 71,063 mechanically ventilated patients in NY, and 41,875 in ON who survived to hospital discharge, median length of initial hospital stay was similar in NY versus ON (15 days, Interquartile range (IQR) 8-28 vs 16 (9-30)), but was systematically shorter in NY when stratified by patient subgroups of different illness severity. Fewer patients in NY were discharged directly home (53.6% versus 71.4%). Of patients in NY, 15,527 (cumulative incidence 21.9%) had a first rehospitalization within 30 days versus 5,531 (cumulative incidence 13.2%) in Ontario, p<0.001. Incidence of rehospitalization was higher in NY across all subgroups assessed, with the greatest differences among patients with a tracheostomy (29.8% versus 13.3%, p<0.001), those who received dialysis during the hospitalization (31.9% versus 17.0%, p<0.001), and for patients not discharged directly home (27.6% versus 13.1% p<0.001).
Conclusions: Mechanically ventilated patients who survive to hospital discharge in NY have shorter hospital stays, with higher rehospitalization rates within 30 days compared with ON
Pilot Weather Advisor System
The Pilot Weather Advisor (PWA) system is an automated satellite radio-broadcasting system that provides nearly real-time weather data to pilots of aircraft in flight anywhere in the continental United States. The system was designed to enhance safety in two distinct ways: First, the automated receipt of information would relieve the pilot of the time-consuming and distracting task of obtaining weather information via voice communication with ground stations. Second, the presentation of the information would be centered around a map format, thereby making the spatial and temporal relationships in the surrounding weather situation much easier to understan

DNA Barcoding in the Cycadales: Testing the Potential of Proposed Barcoding Markers for Species Identification of Cycads
Barcodes are short segments of DNA that can be used to uniquely identify an unknown specimen to species, particularly when diagnostic morphological features are absent. These sequences could offer a new forensic tool in plant and animal conservationâespecially for endangered species such as members of the Cycadales. Ideally, barcodes could be used to positively identify illegally obtained material even in cases where diagnostic features have been purposefully removed or to release confiscated organisms into the proper breeding population. In order to be useful, a DNA barcode sequence must not only easily PCR amplify with universal or near-universal reaction conditions and primers, but also contain enough variation to generate unique identifiers at either the species or population levels. Chloroplast regions suggested by the Plant Working Group of the Consortium for the Barcode of Life (CBoL), and two alternatives, the chloroplast psbA-trnH intergenic spacer and the nuclear ribosomal internal transcribed spacer (nrITS), were tested for their utility in generating unique identifiers for members of the Cycadales. Ease of amplification and sequence generation with universal primers and reaction conditions was determined for each of the seven proposed markers. While none of the proposed markers provided unique identifiers for all species tested, nrITS showed the most promise in terms of variability, although sequencing difficulties remain a drawback. We suggest a workflow for DNA barcoding, including database generation and management, which will ultimately be necessary if we are to succeed in establishing a universal DNA barcode for plants
Meaning in life among adolescents: Factorial invariance of the Purpose in Life Test and buffering effect on the relationship between emotional dysregulation and hopelessness
Objective: The purpose of the present study was threefold: first, to analyse the psychometric properties of a 10âitem Spanish version of the Purpose in Life Test, which assesses meaning in life (MiL), in a sample of community adolescents; second, to analyse the differences between the age and gender groups; and third, to analyse whether MiL buffers the relationship between emotional dysregulation and hopelessness. Method: Participants were 1,599 adolescents from 12 to 19 years old, M = 15.69, SD = 2.14. The Purpose in Life Testâ10 Items, the Beck Hopelessness Scale, and the Difficulties in Emotional Regulation Scale were used. Results: A nineâitem version showed good fit, psychometric properties (internal consistency, construct, and concurrent validity), and factorial invariance across gender and age (12-15 years/16-19 years). Difference in MiL between boys and girls was not significant, whereas between age groups was significant. MiL had a strong buffering effect on the relationship between emotional dysregulation and hopelessness. Discussion: It is desirable to promote the sense of MiL in adolescents. MiL plays a significant and strong mediator role in the relationship between emotional dysregulation and hopelessness, reinforcing the positive role of MiL in mental health and as a resource for facing adversity

Amplification of a Zygosaccharomyces bailii DNA Segment in Wine Yeast Genomes by Extrachromosomal Circular DNA Formation
We recently described the presence of large chromosomal segments resulting from independent horizontal gene transfer (HGT) events in the genome of Saccharomyces cerevisiae strains, mostly of wine origin. We report here evidence for the amplification of one of these segments, a 17 kb DNA segment from Zygosaccharomyces bailii, in the genome of S. cerevisiae strains. The copy number, organization and location of this region differ considerably between strains, indicating that the insertions are independent and that they are post-HGT events. We identified eight different forms in 28 S. cerevisiae strains, mostly of wine origin, with up to four different copies in a single strain. The organization of these forms and the identification of an autonomously replicating sequence functional in S. cerevisiae, strongly suggest that an extrachromosomal circular DNA (eccDNA) molecule serves as an intermediate in the amplification of the Z. bailii region in yeast genomes. We found little or no sequence similarity at the breakpoint regions, suggesting that the insertions may be mediated by nonhomologous recombination. The diversity between these regions in S. cerevisiae represents roughly one third the divergence among the genomes of wine strains, which confirms the recent origin of this event, posterior to the start of wine strain expansion. This is the first report of a circle-based mechanism for the expansion of a DNA segment, mediated by nonhomologous recombination, in natural yeast populations
Towards a collaborative research: A case study on linking science to farmers' perceptions and knowledge on Arabica coffee pests and diseases and its management
The scientific community has recognized the importance of integrating farmer's perceptions and knowledge (FPK) for the development of sustainable pest and disease management strategies. However, the knowledge gap between indigenous and scientific knowledge still contributes to misidentification of plant health constraints and poor adoption of management solutions. This is particularly the case in the context of smallholder farming in developing countries. In this paper, we present a case study on coffee production in Uganda, a sector depending mostly on smallholder farming facing a simultaneous and increasing number of socio-ecological pressures. The objectives of this study were (i) to examine and relate FPK on Arabica Coffee Pests and Diseases (CPaD) to altitude and the vegetation structure of the production systems; (ii) to contrast results with perceptions from experts and (iii) to compare results with field observations, in order to identify constraints for improving the information flow between scientists and farmers. Data were acquired by means of interviews and workshops. One hundred and fifty farmer households managing coffee either at sun exposure, under shade trees or inter-cropped with bananas and spread across an altitudinal gradient were selected. Field sampling of the two most important CPaD was conducted on a subset of 34 plots. The study revealed the following findings: (i) Perceptions on CPaD with respect to their distribution across altitudes and perceived impact are partially concordant among farmers, experts and field observations (ii) There are discrepancies among farmers and experts regarding management practices and the development of CPaD issues of the previous years. (iii) Field observations comparing CPaD in different altitudes and production systems indicate ambiguity of the role of shade trees. According to the locality-specific variability in CPaD pressure as well as in FPK, the importance of developing spatially variable and relevant CPaD control practices is proposed. (Résumé d'auteur
