Deep Vein Thrombosis Prevention in Post-Operative Patient

The purpose of this research was to determine in postoperative patients what was the effect of compression devices in comparison to prophylactic use of anticoagulants in the prevention of deep vein thrombosis (DVT). The method used was a literature review of risk factors contributing to likelihood of DVT and current methods of prevention. Prevention methods that were analyzed included compression devices applied to lower extremities and anticoagulants including: Heparin, Lovenox, and Xarelto. All are excellent methods of prevention of DVT, however prophylactic use of anticoagulants comes with high bleeding risks and both methods are highly dependent on patient compliance. It is recommended that patients be screened thoroughly by using a risk assessment tool to determine likelihood for contracting a DVT before being placed on any preventative measures.

Emissions from a HGV Using Used Cooking Oil as a Fuel under Real World Driving Conditions

To maximize CO2 reduction, refined straight used cooking oils were used as a fuel in Heavy Goods Vehicles (HGVs) in this research. The fuel is called C2G Ultra Biofuel (C2G: Convert to Green Ltd) and is a fully renewable fuel made as a diesel replacement from processed used cooking oil, used directly in diesel engines specifically modified for this purpose. This is part of a large demonstration project involving ten 44-tonne trucks using C2G Ultra Biofuel as a fuel to partially replace standard diesel fuels. A dual fuel tank containing both diesel and C2G Ultra Biofuel and an on-board fuel blending system-Bioltec system was installed on each vehicle, which is able to heat the C2G Ultra Biofuel and automatically determine the required blending ratio of diesel and C2G Ultra Biofuel according to fuel temperature and engine load. The engine was started with diesel and then switched to C2G Ultra Biofuel under appropriate conditions. Exhaust emissions were measured using PEMS (Portable Emission Measurement Systems) on one of the trucks under real world driving conditions. Comparisons of emissions between neat diesel mode and blended fuel mode were made. The results show that C2G Ultra Biofuel can reduce particulate matter (PM) and CO emissions significantly compared to the use of pure diesel

Causes of bimodal melting curve:Asymmetric guaninecytosine (GC) distribution causing two peaks in melting curve and affecting their shapes

The aim of this study was to present a new situation in which a relatively single short PCR-product might show two separate peaks with sequence specific shapes at the dissociation curve. SYBR-Green I real-time RT-PCR was performed on Lhcgr-gene transcripts in rats. Different programs were used for melting curve simulation and estimating Tm. Statistical tests were performed to determine whether two peaks at the dissociation curve were belonging to a single template. A bimodal melting curve was observed in real-time RT-PCR on a short segment (169 bp) of Lhcgr gene with a single band in gel electrophoresis. Sequencing of the Cloned PCR-product was compatible with template sequence. Realtime PCR using the vector conveying interested sequence, showed again two peaks at dissociation curve. The GC-content of first 100 bases (75%) and last 69 bases (42%) were significantly different. DNA melting simulation programs also confirmed the bimodal pattern, although, their height and wideness were different to actual peaks. Due to the asymmetric GC distribution effect on dissociation curve in short sequences, it is highly recommended to use DNA melting simulation programs to predict the number of peaks in the melting curve when designating primers; however, predicted peak shapes are not always accurate.Key words: Asymmetric GC distribution, bimodal melting curve, DNA melting simulation, SYBR-green I realtime PCR

Lee Silverman voice treatment (LSVT) mitigates voice difficulties in mild Parkinson's disease

Background: Parkinson's disease (PD) is a progressive neurological disorder and many PD patients experience some type of voice and speech disorders during the course of illness. In this study, the aim was to investigate the effect of Lee Silverman voice treatment (LSVT) on improving voice difficulties in patients with mild PD using voice handicap index (VHI). Methods: This interventional study was conducted on 23 PD patients who were randomly divided into 2 groups: a treatment group (PD-T) (n=13) and a no-treatment group (PD-NT) (n=10). Neurologically healthy control (NNC) group consisted of 13 healthy participants who did not suffer from voice and speech problems and were matched with PD group by age (50-65 years), sex, and education. VHI questionnaire was completed a day before the start of LSVT and a day after the treatment fulfillment for the PD-T group; the same time spots were applied for the PD-NT and NNC groups. Statistical analyses were performed using SPSS Statistics 22.0 and significance level was set at 0.05. The multivariate analysis of variance and repeated measure analysis of variance were used for data analysis. Results: PD groups showed a significant weakness in VHI scores before treatment compared to NNC group (p < 0.001). The mean of VHI scores for PD-T, PD-NT, and NNC groups before treatment was 44.31±11.23, 43.54±6.10, and 8.15±4.27, respectively. LSVT was successful in improving VHI scores in PD-T group (17.23±5.35, p < 0.001). However, no improvement was observed in PD-NT group (44.00±5.88). Conclusion: Improvement in VHI score could be the result of ameliorated self-monitoring and self-regulation created by LSVT. © Iran University of Medical Sciences

Hypertension in Acromegaly in Relationship to Biochemical Control and Mortality: Global ACROSTUDY Outcomes

Context: Hypertension is a major cardiovascular risk factor related to increased mortality in acromegaly. Surgical cure of acromegaly is associated with improvement in blood pressure levels, however little is known about the effect of pegvisomant (PEGV) treatment in patients with hypertension. This analysis evaluates outcomes in patients with hypertension and acromegaly included in ACROSTUDY. Methods: ACROSTUDY is a global non-interventional surveillance study of long-term treatment with PEGV, monitoring its safety and efficacy. The cohort was retrospectively divided in two subgroups: patients with and without hypertension. Stepwise logistic regression and Kaplan-Meyer analyses were performed for testing predictors of mortality. Results: The tota

Social Media, Gender and the Mediatisation of War: Exploring the German Armed Forces’ Visual Representation of the Afghanistan Operation on Facebook

Studies on the mediatisation of war point to attempts of governments to regulate the visual perspective of their involvements in armed conflict – the most notable example being the practice of ‘embedded reporting’ in Iraq and Afghanistan. This paper focuses on a different strategy of visual meaning-making, namely, the publication of images on social media by armed forces themselves. Specifically, we argue that the mediatisation of war literature could profit from an increased engagement with feminist research, both within Critical Security/Critical Military Studies and within Science and Technology Studies that highlight the close connection between masculinity, technology and control. The article examines the German military mission in Afghanistan as represented on the German armed forces’ official Facebook page. Germany constitutes an interesting, and largely neglected, case for the growing literature on the mediatisation of war: its strong antimilitarist political culture makes the representation of war particularly delicate. The paper examines specific representational patterns of Germany’s involvement in Afghanistan and discusses the implications which arise from what is placed inside the frame of visibility and what remains out of its view
