e isotope feeding and genome annotation-based comparative metabolic network analysis that the Entner-Doudoroff pathway and non-OxPPP bypass glycolysis and OxPPP during the oxidation of glucose, a component of the host xylem pool that serves as a potential carbon source (5). The outcomes help better define the central carbon metabolic network of R. solanacearum that can be integrated with 13C metabolic flux analysis as well as flux balance analysis studies for defining the metabolic phenotypes. The study highlights the need to critically examine phytopathogens whose metabolism is poorly understood.

Required for this is suitable software that extracts the information contained in the four-dimensional (4D) data space spanned by m/z, retention time, ion mobility and signal intensity. Here we describe the ion mobility enhanced MaxQuant software, which utilizes the added data dimension. It offers an end to end computational workflow for the identification and quantification of peptides and proteins in LC-IMS-MS/MS shotgun proteomics data. We apply it to trapped ion mobility spectrometry (TIMS) coupled to a quadrupole time-of-flight (QTOF) analyzer. A highly parallelizable 4D feature detection algorithm extracts peaks which are assembled to isotope patterns. Masses are recalibrated with a non-linear m/z, retention time, ion mobility and signal intensity dependent model, based on peptides from the sample. A new matching between runs (MBR) algorithm that utilizes collisional cross section (CCS) values of MS1 features in the matching process significantly gains specificity from the extra dimension. Prerequisite for using CCS values in MBR is a relative alignment of the ion mobility values between the runs. The missing value problem in protein quantification over many samples is greatly reduced by CCS aware MBR.MS1 level label-free quantification is also implemented which proves to be highly precise and accurate on a benchmark dataset with known ground truth. MaxQuant for LC-IMS-MS/MS is part of the basic MaxQuant release and can be downloaded from http//maxquant.org.

Recent data using culture-independent techniques assessing the microbiome in healthy subjects have demonstrated that chronic microaspiration establishes a very similar microbial community between the mouth and lung, suggesting these 2 anatomic regions are closely intertwined. Dental disease is driven and aided by a dysbiosis in the oral microbiome, and evidence is mounting that implicates the microbiome in a variety of lung diseases including asthma, COPD, pulmonary fibrosis, and pneumonia. This review describes common dental conditions and potential mechanisms by which poor oral health may contribute to lung disease. We also review the current literature drawing associations between poor oral health and lung disease.

Historically, simple equations using age, height, and sex were used to "predict" normal lung function. However, these multiple factors interact in complex ways to determine what the expected lung function values are in healthy subjects. Healthy individuals exhibit a wide range of variability for most pulmonary function variables, and this variability is not consistent across all age ranges. Recent analysis of large groups of healthy subjects has allowed the development of sophisticated prediction models that take into account not only variability but also skew that occurs as the lungs develop and mature. These modern reference equations provide uninterrupted expected values from early childhood, through adolescence and adulthood, and extending into the ninth decade. Modern equations use upper and lower limits of normal to offer a statistically robust means of defining who is within normal limits. Despite these advances, interpretation of pulmonary function test results has not been highly standardized, largely because interpretation depends on the reference equations used and, more importantly, how they are applied. This review discusses the strengths and limitations of using reference equations to interpret pulmonary function data in the context of research and clinical practice.

The purpose of this study was to describe current RT intubation practices in North Carolina through the use of a survey instrument. METHODS A survey was developed by the authors using REDCap. The survey was sent via email to all licensed RTs in North Carolina. Information collected included respondent demographics, intubation practices (including training and skill maintenance), and attitudes about RT intubation practices. RESULTS Of the 411 respondents, 68% intubated at their facility, representing 81 unique institutions. RTs who performed intubation were more likely to be from community hospitals and less likely to be from level 1 trauma centers. Respondents reported intubating adult (91%), pediatric (61%), and neonatal (65%) patients. The most common areas in which RTs reported performing intubation were the adult ICU (80%), emergency department (76%), outside the operating room for emergencies (76%), neonatal ICU (43%), the delivery room (45%), and pediatric ICU (25%). The median (interquartile range) number of supervised intubations required to be considered competent was 5 (3-5). The most common numbers of intubations required to be considered competent were 5 (32%), 3 (26%), 10 (16%), 2 (4%), and 0 (3%). The perceived number of intubations to achieve competence was 6 (range 5-10) and did not differ based on years of experience. Most respondents believed their RT intubation program was safe (93%) and effective (91%), and that RTs were well-trained (81%), that their intubation skills were objectively evaluated (66%), and that RTs receive sufficient feedback on performance (68%). CONCLUSIONS RTs in North Carolina frequently performed intubation and had high confidence in their programs. buy GRL0617 Further studies are needed to establish standardized training for endotracheal intubation, document success rates for intubations, and evaluate the use of video laryngoscopy by RTs.
