Abstract

The accessibility of high-throughput sequencing has revolutionized many fields of biology. In order to better understand host-associated viral and microbial communities, a comprehensive workflow for DNA and RNA extraction was developed. The workflow concurrently generates viral and microbial metagenomes, as well as metatranscriptomes, from a single sample for next-generation sequencing. The coupling of these approaches provides an overview of both the taxonomical characteristics and the community encoded functions. The presented methods use Cystic Fibrosis (CF) sputum, a problematic sample type, because it is exceptionally viscous and contains high amount of mucins, free neutrophil DNA, and other unknown contaminants. The protocols described here target these problems and successfully recover viral and microbial DNA with minimal human DNA contamination. To complement the metagenomics studies, a metatranscriptomics protocol was optimized to recover both microbial and host mRNA that contains relatively few ribosomal RNA (rRNA) sequences. An overview of the data characteristics is presented to serve as a reference for assessing the success of the methods. Additional CF sputum samples were also collected to (i) evaluate the consistency of the microbiome profiles across seven consecutive days within a single patient, and (ii) compare the consistency of metagenomic approach to a 16S ribosomal RNA gene-based sequencing. The results showed that daily fluctuation of microbial profiles without antibiotic perturbation was minimal and the taxonomy profiles of the common CF-associated bacteria were highly similar between the 16S rDNA libraries and metagenomes generated from the hypotonic lysis (HL)-derived DNA. However, the differences between 16S rDNA taxonomical profiles generated from total DNA and HL-derived DNA suggest that hypotonic lysis and the washing steps benefit in not only removing the human-derived DNA, but also microbial-derived extracellular DNA that may misrepresent the actual microbial profiles.

Abstract

Background
Carbon monoxide poisoning (COP) often produces severe complications and can be fatal. Because this topic has not been well delineated, we investigated long-term prognoses of patients with COP (COP[+]).

Methods
In this retrospective nationwide cohort study, 441 COP[+] patients and 8820 COP[−] controls (120) from 1999 to 2010 were selected from Taiwan’s National Health Insurance Research Database.

Results
Thirty-seven (8.39%) COP[+] patients and 142 (1.61%) controls died (P<0.0001) during follow-up. Incidence rate ratios (IRR) of death were 5.24 times higher in COP[+] patients than in controls (P<0.0001). The risk of death was particularly high in the first month after COP (IRR: 308.78; 95% confidence interval [CI]: 40.79-2337.56), 1 to 6 months after (IRR: 18.92; 95% CI: 7.69-46.56), and 6-12 months after (IRR: 4.73; 95% CI: 1.02-21.90). After adjusting for age, gender, and selected comorbidities, the hazard ratio of death for COP[+] patients was still 4.097 times higher than for controls. Moreover, older age (≥30 years old), male gender, diabetes mellitus, hypertension, and low income were also independent mortality predictors. Conclusions COP significantly increases the risk for long-term mortality. Early follow-up and secondary prevention of death are needed for patients with COP.

Abstract

Control and manipulation of synthesis parameters of thin film coatings is of critical concern in determination of material properties and performance. Structural and morphological properties of rf-sputtered WC-Co thin films deposited under varying deposition parameters namely, substrate temperature and rf power are presented in this data article. The surface morphology, crystallite size and nature were acquired using x-ray photoelectron spectroscopy (XPS) and Grazing Incidence X-ray absorption spectroscopy (GI-XAS). Furthermore, Synchrotron findings are correlated with complimentary data acquired from Scanning electron microscopy (SEM), Raman spectroscopy and surface profilometry to predict and point out optimum synthesis parameters for best properties of the film.
