Prospective observational study on tracheal tube cuff pressures in emergency patients– is neglecting the problem the problem?
Authors: Harm Falko , Zuercher Mathias , Bassi Marco , Ummenhofer Wolfgang 
Published: December 2013

Abstract

Background
Inappropriately cuffed tracheal tubes can lead to inadequate ventilation or silent aspiration, or to serious tracheal damage. Cuff pressures are of particular importance during aeromedical transport as they increase due to decreased atmospheric pressure at flight level. We hypothesised, that cuff pressures are frequently too high in emergency and critically ill patients but are dependent on providers’ professional background.

Methods
Tracheal cuff pressures in patients intubated before arrival of a helicopter-based rescue team were prospectively recorded during a 12-month period. Information about the method used for initial cuff pressure assessment, profession of provider and time since intubation was collected by interview during patient handover. Indications for helicopter missions were either Intensive Care Unit (ICU) transports or emergency transfers. ICU transports were between ICUs of two hospitals. Emergency transfers were either evacuation from the scene or transfer from an emergency department to a higher facility.

Results
This study included 101 patients scheduled for aeromedical transport. Median cuff pressure measured at handover was 45 (25.0/80.0) cmH2O; range, 8-120 cmH2O. There was no difference between patient characteristics and tracheal tube-size or whether anaesthesia personnel or non-anaesthesia personnel inflated the cuff (30 (24.8/70.0) cmH2O vs. 50 (28.0/90.0) cmH2O); p = 0.113.
With regard to mission type (63 patients underwent an emergency transfer, 38 patients an ICU transport), median cuff pressure was different: 58 (30.0/100.0) cmH2O in emergency transfers vs. 30 (20.0/45.8) cmH2O in inter-ICU transports; p < 0.001. For cuff pressure assessment by the intubating team, a manometer had been applied in 2 of 59 emergency transfers and in 20 of 34 inter-ICU transports (method was unknown for 4 cases each). If a manometer was used, median cuff pressure was 27 (20.0/30.0) cmH2O, if not 70 (47.3/102.8) cmH2O; p < 0.001.

Conclusions
Cuff pressures in the pre-hospital setting and in intensive care units are often too high. Interestingly, there is no significant difference between non-anaesthesia and anaesthesia personnel. Acceptable cuff pressures are best achieved when a cuff pressure manometer has been used. This method seems to be the only feasible one and is recommended for general use.
Quality of Life Indicators for Individuals With Intellectual Disabilities: Extending Current Practice
Authors: Brown Ivan , Hatton Chris , Emerson Eric 
Published: December 2013

Abstract
Quality of life is a social construct that is measured by what are considered to be its most appropriate indicators. Quality of life measurement in intellectual disability reflects a variety of indicators, often grouped under life domains. Subjective and objective methods of measuring indicators each have strengths and drawbacks, but it is currently considered best to use both methods. Indicators of quality of life that are common to all people have been measured to date, although indicators that are unique to individuals are highly useful for enhancing individual development and for applying person-centered practice. Aggregate quality of life data from individuals may not always be the best source of information for evaluating policies and service practices. A case is made for supplementing quality of life frameworks or adopting other frameworks for these purposes, with the Capabilities Framework offered as an example. Further, an argument is made that a pragmatic approach might best be taken to policy and program evaluation, whereby the key criterion for using a conceptual framework and set of indicators is its usefulness in effecting positive change in people's lives.
A Family of Mortality Jump Models Applied to US Data
Authors: Chen Hua 
Published: December 2013

Abstract
Mortality models are fundamental to quantify mortality/longevity risks and provide the basis of pricing and reserving. In this article, we consider a family of mortality jump models and propose a new generalized Lee–Carter model with asymmetric double exponential jumps. It is asymmetric in terms of both time periods of impact and frequency/severity profiles between adverse mortality jumps and longevity jumps. It is mathematically tractable and economically intuitive. It degenerates to a transitory exponential jump model when fitting the US mortality data and is the best fit compared with other jump models.

CFD Modeling and Experimental Study of a Spray Dryer Performance
Authors: Sadripour Maryam , Rahimi Amir , Hatamipour Mohammad Sadegh 
Published: December 2013

Abstract
The performance of a pilot-scale spray dryer is investigated experimentally and theoretically. The governing equations for flow field, heat and mass transfer, and particle trajectory are solved by applying computational fluid dynamics (CFD). The effects of inlet air temperature and initial particle diameter on the outlet humidity and particle residence time are examined. These parameters should be considered carefully in proper designing of spray dryers especially for the heat-sensitive products. The model is validated with an error of 5.5%.

Suppression of Expression Between Adjacent Genes Within Heterologous Modules in Yeast

Published: December 2013

Abstract
Recent studies have shown that proximal arrangement of multiple genes can have complex effects on gene expression. For example, in the case of heterologous gene expression modules, certain arrangements of the selection marker and the gene expression cassette may have unintended consequences that limit the predictability and interpretability of module behaviors. The relationship between arrangement and expression has not been systematically characterized within heterologous modules to date. In this study, we quantitatively measured gene expression patterns of the selection marker (KlURA3 driven by the promoter, pKlURA) and the gene expression cassette (GFP driven by the galactose-inducible GAL1 promoter, pGAL1) in all their possible relative arrangements in Saccharomyces cerevisiae. First, we observed that pKlURA activity depends strongly on the relative arrangement and the activity of pGAL1. Most notably, we observed transcriptional suppression in the case of divergent arrangements: pKlURA activity was reduced when pGAL1 was inactive. Based on our nucleosome occupancy data, we attribute the observed transcriptional reduction to nucleosome repositioning. Second, we observed that pGAL1 activity also depends on the relative arrangement of pKlURA. In particular, strains with divergent promoters showed significantly different pGAL1 activation patterns from other strains, but only when their growth was compromised by lack of uracil. We reasoned that this difference in pGAL1 activation patterns arises from arrangement-dependent pKlURA activity that can affect the overall cell physiology (i.e., cell growth and survival in the uracil-depleted condition). Our results underscore the necessity to consider ramifications of promoter arrangement when using synthetic gene expression modules.

Published: December 2013

AbstractAssociation mapping is a widely applied method for elucidating the genetic basis of phenotypic traits. However, factors such as linkage disequilibrium and levels of genetic diversity influence the power and resolution of this approach. Moreover, the presence of population subdivision among samples can result in spurious associations if not accounted for. As such, it is useful to have a detailed understanding of these factors before conducting association mapping experiments. Here we conducted whole-genome sequencing on 24 specimens of the malaria mosquito vector, Anopheles arabiensis, to further understanding of patterns of genetic diversity, population subdivision and linkage disequilibrium in this species. We found high levels of genetic diversity within the An. arabiensis genome, with ~800,000 high-confidence, single- nucleotide polymorphisms detected. However, levels of nucleotide diversity varied significantly both within and between chromosomes. We observed lower diversity on the X chromosome, within some inversions, and near centromeres. Population structure was absent at the local scale (Kilombero Valley, Tanzania) but detected between distant populations (Cameroon vs. Tanzania) where differentiation was largely restricted to certain autosomal chromosomal inversions such as 2Rb. Overall, linkage disequilibrium within An. arabiensis decayed very rapidly (within 200 bp) across all chromosomes. However, elevated linkage disequilibrium was observed within some inversions, suggesting that recombination is reduced in those regions. The overall low levels of linkage disequilibrium suggests that association studies in this taxon will be very challenging for all but variants of large effect, and will require large sample sizes.

Published: December 2013

AbstractMethods for altering the sequence of endogenous Drosophila melanogaster genes remain labor-intensive. We have tested a relatively simple strategy that enables the introduction of engineered mutations in the vicinity of existing P-elements. This method was used to generate useful alleles of the roX1 gene, which produces a noncoding RNA involved in dosage compensation. The desired change was first introduced into a genomic clone of roX1 and transgenic flies were generated that carry this sequence in a P-element. Targeted transposition was then used to move the P-element into roX1. Remobilization of the targeted insertion produced large numbers of offspring carrying chromosomes that had precisely introduced the engineered sequences into roX1. We postulate that this occurred by gap repair, using the P-element on the sister chromatid as template. This strategy was used to introduce six MS2 loops into the roX1 gene (roX1MS2-6), enabling detection of roX1 RNA by a MCP-GFP fusion protein in embryos. The roX1MS2-6 remains under the control of the authentic promoter and within the correct genomic context, features expected to contribute to normal roX1 function. The ability to replace relatively large blocks of sequence suggests that this method will be of general use.
Uncovering Buffered Pleiotropy: A Genome-Scale Screen formel-28Genetic Interactors inCaenorhabditis elegans

Published: December 2013

Abstractmel-28 (maternal-effect-lethal-28) encodes a conserved protein required for nuclear envelope function and chromosome segregation in Caenorhabditis elegans. Because mel-28 is a strict maternal-effect lethal gene, its function is required in the early embryo but appears to be dispensable for larval development. We wanted to test the idea that mel-28 has postembryonic roles that are buffered by the contributions of other genes. To find genes that act coordinately with mel-28, we did an RNA interference−based genetic interaction screen using mel-28 and wild-type larvae. We screened 18,364 clones and identified 65 genes that cause sterility in mel-28 but not wild-type worms. Some of these genes encode components of the nuclear pore. In addition we identified genes involved in dynein and dynactin function, vesicle transport, and cell-matrix attachments. By screening mel-28 larvae we have bypassed the requirement for mel-28 in the embryo, uncovering pleiotropic functions for mel-28 later in development that are normally provided by other genes. This work contributes toward revealing the gene networks that underlie cellular processes and reveals roles for a maternal-effect lethal gene later in development.
Degree of Conversion and Hardness of a Silorane-Based Composite Resin: Effect of Light-Curing Unit and Depth
Authors: Torres SAS , Silva GC , Maria DA , Campos WRC , Magalhães CS , Moreira AN 
Published: December 2013

SUMMARY

Purpose
To investigate the effect of different light-curing units and depths on the degree of conversion (DC) through Fourier transform infrared spectroscopy (FTIR) and Knoop Hardness Number (KHN) of a silorane-based composite resin (Filtek LS, 3M ESPE, St Paul, MN, USA) (LS).

Materials and Methods
LS specimens mounted in a particular designed matrix were photoactivated by three light-cure units (LCUs) at depths of 2, 3, 4, and 5 mm. The DC was determined in a FTIR spectrometer with an attenuated total reflectance accessory. The KHN was measured in an automatic microhardness tester. The results were analyzed using the Friedman and Spearman statistical tests (α=0.05).

Results
There was no effect of LCUs on the DC (p=0.472) or KHN (p=0.174) for all of the studied depths. The highest DC and KHN means were found at 2-mm depth, which were not statistically different from 3-mm depth, but were higher than 4-mm and 5-mm depths (p=0.007). Spearman analysis found a positive linear correlation between the variables KHN and DC (r=0.858, p&lt;0.000).

Conclusions
The LCUs' effect was not verified. Values of DC and KHN for LS decreased with increasing depth. The highest values for both DC and KHN were obtained at depths of 2-3 mm.
Polymerization Shrinkage and Depth of Cure of Bulk Fill Flowable Composite Resins
Authors: Garcia D , Yaman P , Dennison J , Neiva GF 
Published: December 2013

SUMMARY

Objective
To evaluate polymerization shrinkage and depth of cure of two bulk fill flowable composites, one nanohybrid composite modified to a flowable consistency, and one standard flowable composite, comparing the scraping method to the Knoop hardness test.

Methods
Two bulk fill flowable composites, SureFil SDR flow (SSF) (Dentsply) and Venus Bulk Fill (VBF) (Heraeus Kulzer), one standard flowable, Filtek Supreme Ultra Flowable (FSUF) (3M/ESPE) (control), and one regular bulk composite that can be made flowable, SonicFill (SF) (Kerr), were used in this study. For polymerization shrinkage (PS), ten 2-mm samples were made for each composite and cured for 20 seconds and shrinkage was measured with a Kaman linometer. For hardness, ten specimens of each composite were made in a 10 × 10-mm mold and cured for 20 seconds; the bottom surface was scraped according to ISO 4049 specification, and the remaining thickness was measured with a micrometer. Hardness samples were prepared at 2-, 3-, 4-, and 5-mm thick ×14-mm diameter, cured for 20 seconds, and polished. After 24 hours of dry storage, a Knoop indenter was applied at 100 g load for 11 seconds. Three readings were made on the top and bottom of each specimen and averaged for each surface to calculate a Knoop hardness value and a bottom/top hardness ratio. One-way analysis of variance and Tukey tests were used to determine significant differences between thicknesses and between test methods for each material.

Results
PS values were 3.43 ± 0.51%, 3.57 ± 0.63%, 4.4 ± 0.79%, and 1.76 ± 0.53% for FSUF, SSF, VBF, and SF, respectively. VBF showed significantly greater shrinkage (4.4 ± 0.79%), followed by FSUF (3.43 ± 0.51%) and SSF (3.57 ± 0.63%), which were similar, and SF (1.76 ± 0.53%), which had significantly less shrinkage (p&lt;0.05). Values for the scraping method for depth of cure were significantly greater for SSF and VBF (&gt;5.0 mm), followed by SF (3.46 ± 0.16 mm) and FSU (2.98 ± 0.22 mm). Knoop top hardness values (KHN) were: VBF 21.55 ± 2.39, FSUF 44.62 ± 1.93, SSF 29.17 ± 0.76, and SF 72.56 ± 2.4 at 2 mm and were not significantly different at 3-, 4-, and 5-mm thick within each material. Ratios for bottom/top values (depth of cure) for 2, 3, 4, and 5 mm were: VBF 0.80 ± 0.1, 0.78 ± 0.03, 0.67 ± 0.10, and 0.59 ± 0.07, respectively; SSF 0.74 ± 0.08, 0.72 ± 0.08, 0.69 ± 0.18, and 0.62 ± 0.08, respectively; SF 0.82 ± 0.05, 0.68 ± 0.05, 0.47 ± 0.04, and 0.21 ± 0.02, respectively; and FSUF 0.56 ± 0.08 at 2 mm and 0.40 ± 0.08 at 3 mm. The bottom/top ratio was .80 or less at all depths and decreased below 0.70 at 4-mm depth for VBF and SSF, at 3 mm for SF and at 2 mm for FSUF.
Cineole, Thymol and Camphor Nasal Challenges and their Effect on Nasal Symptoms and Cough in an Animal Model
Authors: Gavliakova S , Dolak T , Licha H , Krizova S , Plevkova J 
Published: December 2013

Abstract
Inhalation of aromatic vapours suppressed coughing induced by citric acid (CA) in naive animals. No data are available about their effects in an animal model with primarily up-regulated cough reflex. New data indicate that aromatic vapours suppress cough via effect on nasal sensory nerves.
The aim of our study was to ascertain the efficacy of nasal application of 1,8-cineole, thymol and camphor on nasal symptoms and CA induced cough in validated model of up-regulated cough reflex. Guinea pigs (n=13) were sensitized by intraperitoneal administration of ovalbumin (OVA) and sensitization was confirmed 21 days later by skin tests. Sensitized animals were repeatedly challenged with nasal OVA to induce rhinitis, and further experiments (cough challenges) were performed during the early phase of allergic inflammation.
Cough was induced by CA in plethysmograph for 10 minutes after nasal pre-treatment with aromatic substances (10-3M) in rhinitis model. Cough was recognized from record of sudden airflow changes interrupting breathing pattern and cough sound. Final count of coughs was established by blind analysis using SonicVisualiser Software. Dose responses curves, total cough count and cough latency were analyzed.
Repeated intranasal challenge with OVA induces progressively worsening symptoms, and cough induced by CA during acute phase of allergic rhinitis was enhanced. Nasal pre-treatment with 1,8-cineole, thymol and camphor did not prevent onset of nasal symptoms, and the magnitude of symptoms was comparable to those without pretreatment. Camphor had the most potent antitussive effects (number of coughs 25±3 vs. 7±2, p<0.05) followed by thymol (number of coughs 25±3 vs. 14±2, p<0.05). The data for nasal 1,8-cineole challenge did not reach statistical significance. Cough latency followed this trend.
Although the magnitude of nasal symptoms is not influenced, the effect on cough is in case of camphor and thymol significant. Our data showed that nasal application of aromatic substances suppress citric acid induced cough in animals with up-regulated cough reflex.
Possibilities of a Combined Biophysical Non-Invasive Fetal Monitoring During Labour in Reducing the Frequency of Operative Deliveries – A Randomized Study
Authors: Dokus K , Matasova K , Visnovsky J , Dokusova S , Danko J. 
Published: December 2013

Abstract
Objective. The aim of the study was to test the performance and safety of fetal pulse oximetry (FPO) in the management of non-reassuring CTG patterns in labour.
Materials. A randomized controlled trial was conducted in 648 women in active labour and pregnancies > 36 weeks with reassuring admission CTG followed by non-reassuring patterns. All women were divided into 2 groups according to the mode of fetal intrapartum monitoring used. In the study group (n=324), women received a combined biophysical fetal monitoring with CTG plus FPO (n=324), while the control group of women had CTG alone monitoring. Main outcome measures were rates of operative deliveries and neonatal outcome.
Results. The analysis showed a significant reduction of Caesarean deliveries in the study group receiving a combined fetal monitoring compared to controls (45/324 vs. 67/324; P=0.022). The total operative delivery rate was also lower, but not significantly (92/324 vs. 104/324, P=0.302). No comparative differences were observed in neonatal outcomes, except for 2 controls-group neonates born with pH-UA < 7.1, however completely normal further postnatal course. No such case was encountered in the study group neonates, and no perinatal deaths occurred during the study.
Conclusions. A combined biophysical intrapartum fetal monitoring with CTG and fetal pulse oximetry enables safe reduction in Caesarean rate for non-reassuring CTG patterns, however it could not decrease a total operative delivery rate. Condensation: Fetal pulse oximetry safely reduces a Caesarean rate for non-reassuring patterns, but not the overall Caesarean rate.

Authors: Bogumił Aleksandra , Paszt Lidia Sas , Lisek Anna , Trzciński Paweł , Harbuzov Anton 
Published: December 2013

ABSTRACT
The antagonistic activity of 52 isolates of Trichoderma spp. against Botrytis cinerea was tested in in vitro conditions using the dual culture technique. The results revealed that all of the Trichoderma isolates had the ability to inhibit the mycelial growth of grey mould. The percentage reduction in the growth of Botrytis cinerea after six days of incubation at 25ºC varied between 45-78%. The isolates Tr43 and Tr52 showed the highest antagonistic activity (Tr43 - 76%; Tr52 - 78%). Biochemical and molecular identification indicated that both isolates were T. atroviride. The isolates showed differences in the utilisation of 11 to 96 different carbon sources. Additional biochemical tests revealed the ability of Tr43 and Tr52 to produce siderophores, indole-3-acetic acid and chitinases. Neither of the isolates gave positive results regarding phosphate solubilisation on Pikovskaya’s medium.
