Left ventricular assist devices improve survival prospects in patients with end-stage heart failure; however, infection complicates up to 59% of implantation cases. How many of these infections are caused by multidrug-resistant organisms is unknown. We sought to identify the incidence, risk factors, and outcomes of multidrug-resistant organism infection in patients who have left ventricular assist devices.
We retrospectively evaluated the incidence of multidrug-resistant organisms and the independent risk factors associated with them in 57 patients who had permanent left ventricular assist devices implanted at our institution from May 2007 through October 2011. Outcomes included death, transplantation, device explantation, number of subsequent hospital admissions, and number of subsequent admissions related to infection. Infections were categorized in accordance with criteria from the Infectious Diseases Council of the International Society for Heart and Lung Transplantation.
Multidrug-resistant organism infections developed in 18 of 57 patients (31.6%)—a high incidence. We found 3 independent risk factors: therapeutic goal (destination therapy vs bridging), P=0.01; body mass index, P=0.04; and exposed velour at driveline exit sites, P=0.004. We found no significant differences in mortality, transplantation, or device explantation rates; however, there was a statistically significant increase in postimplantation hospital admissions in patients with multidrug-resistant organism infection. To our knowledge, this is the first report in the medical literature concerning multidrug-resistant organism infection in patients who have permanent left ventricular assist devices.

Published: November 2015

Data regarding thrombolytic treatment of right-sided mechanical valve thrombosis are almost nonexistent, and all current guidelines arise from very small case series. We retrospectively studied the in-hospital and long-term outcome data of a larger series of patients who had received, from September 2005 through June 2012, thrombolytic therapy for right-sided mechanical pulmonary valve or tricuspid valve thrombosis.
We identified 16 patients aged 8–67 years who had undergone thrombolytic therapy for definite thrombotic mechanical valve obstruction in the tricuspid or pulmonary valve position (8 in each position). All study patients except one had subtherapeutic international normalized ratios. The 8 patients with pulmonary mechanical valve thrombosis had a 100% response rate to thrombolytic therapy, and their in-hospital survival rate was also 100%. The 8 patients with tricuspid mechanical valve thrombosis had a 75% response rate to thrombolytic therapy, with an in-hospital survival rate of 87.5%. The one-year survival rate for mechanical valve thrombosis treated with thrombolytic therapy (whether pulmonary or tricuspid) was 87.5%.
On the basis of our data, we recommend that thrombolytic therapy remain the first-line therapy for right-sided mechanical valve thrombosis in adults or children—including children with complex congenital heart disease and patients with mechanical pulmonary valve thrombosis. Surgery should be reserved for patients in whom this treatment fails.
Palynostratigraphy, palynofacies and depositional environment of a lignite-bearing succession at Surkha Mine, Cambay Basin, north-western India
Authors: Monga Priyanka , Kumar Madhav , Prasad Vandana , Joshi Yogesh 
Published: November 2015

Abstract
The paper reports palynology and palynofacies studies of lignite-bearing sediments exposed in an opencast mine succession at Surkha, Bhavnagar District, in the coastal region of Gujarat, India. The study examined the relationships between the palynoflora, sedimentary organic matter and environment at the time of deposition of lignite and associated sediments. Based on dinoflagellate cyst biostratigraphy, the sedimentary succession is dated as early Eocene (Ypresian). Palynofacies studies helped reveal the palaeoenvironmental fluctuations. The dominance of angiosperm pollen grains, freshwater algae, microthyraceous fungi and a large share of land debris in the lower part of the succession suggests a freshwater swamp environment of deposition for the basal lignite facies. Two cenozones - Matanomadiasulcites maximus and Lakiapollis ovatus - were identified in the lower lignite facies, determined from the dominance of these pollen grains in the palynological assemblages. The presence of angiosperm pollen grains and pteridophyte spores in the carbonaceous shale horizon above the lignite facies indicates a change in the depositional regime from freshwater swamp to lagoonal. This was identified as the Arecipites wodehousei cenozone due to its numerical abundance in the assemblage. Dinoflagellate cyst abundance and diversity, and microforaminiferal test linings along with well-sorted terrestrial debris in the mudstone in the upper part of the succession suggest a more open marine estuarine type of depositional environment. The Homotryblium complex along with Cordospheridium fibrospinosum, Kenleyia sp., and Thalassiphora pelagica dinoflagellate cysts are the main representatives of this zone, determined as the Homotryblium tenuispinosum cenozone. The changing depositional settings (freshwater swamp-lagoonal-estuarine) along the vertical succession indicate a marine transgression in this region. Results from palynological studies of early Palaeogene successions of the Cambay and Kutch basins correlate well with the present findings.
Antiretroviral Therapy – Changes of Basic Laboratory Parameters in Hiv-Infected Bulgarian Patients
Authors: Stojanova Yancheva Nina 
Published: November 2015

Summary
HIV-1 infection keeps on being a global problem because of its pandemic character and the impossibility for eradication. The combined antiretroviral therapy (АRТ) remains the only treatment which has proven its effectiveness for maintaining the life of HIV positive patients. Because of long term (life time) duration of this therapy, it is necessary to monitor patients for possible drug toxicity. The aim of our research is to evaluate the changes of basic laboratory examinations while conducting a long-term АRТ. We analyzed basic laboratory studies of 145 HIV-infected Bulgarian patients in the current research. The patients were separated into four groups according to their treatment regimen. They were on dispensary monitoring and were being treated in the Department for Patients with Acquired Immune Deficiency in the Specialized Hospital for Active Treatment of Infectious and Parasitic Diseases “Prof. Ivan Kirov” - Sofia. Our results showed that combined ART led to changes in blood count, alanin-aminotransferase (ALT), glucose and total cholesterol. Some of these changes are significant for some of the drugs administered. The current ART does not lead to severe toxicity and life-threatening conditions such as those which were observed in the first few years of ART introduction.

Abstract
The aim of this study was to assess the changes in hematological and plasma indices of Ctenopharyngodon idella (Val.) with regard to age, sex, and hormonal treatment. Sixty specimens of C. idella, comprising fifteen of each age (6, 12, 24, and 36 months) were used to evaluate the age factor. Additionally, 20 fish, both females and males, were designated to determine blood indices with regard to sex and hormonal treatment. The following biochemical indexes were determined in the blood plasma: glucose, cholesterol, triglycerides, and total protein (TP). Glucose and triglyceride levels differed significantly among ages, and significant age-related differences were noted in the values of red blood cell (RBC), white blood cell (WBC), hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). There were no significant differences in any parameters between males and females. In conclusion, our results showed that the plasma parameter profile could be affected by age (RBC, WBC, Hb, MCV, MCH, MCHC, glucose, triglycerides) and hormonal treatment (lymphocytes and eosinophils). The blood plasma biochemical and hematological profiles permitted assessing physiological state, which provided useful information for monitoring changes in the health status of the fish.
Optical glass: standards – present state and outlook
Authors: Hartmann Peter 
Published: November 2015

Abstract
In 1996, the international organization for standardization ISO started the standards series ISO 10110 specifying indications in drawings of optical elements. Three parts cover material properties: part 2 (stress birefringence), 3 (bubbles and inclusions), and 4 (inhomogeneity and striae). Customers used to just send optical element drawings to glass manufacturers often leading to uncertainty, overspecification, and delivery problems. The raw glass standard ISO 12123 of 2010 allows direct addressing of raw glass specifications. Harmonizing ISO 10110 with ISO 12123 and progress in inspection methods require updating of the material specifying parts. A new part 18 containing all properties is under preparation and is meant to replace parts 2–4. ISO 12123 will be amended by introducing definitions for relative partial dispersions and reference normal lines and grade denominations for tolerance ranges. The working draft ISO/WD 10110 part 18 extends indication possibilities to allow relating to ISO 12123 while ensuring backward compatibility. Default optical glass quality and direct specification of raw glass simplify tolerancing considerably. Annexes support selection of appropriate quality classes referring to optical element size categories. Test and inspection standards on chemical resistances, hardness, stress birefringence, and optical homogeneity will be maintained. Standards for water resistance, refractive index, and striae inspection are being prepared.

Secured Document Sharing Using Visual Cryptography in Cloud Data Storage
Authors: Brindha K. , Jeyanthi N. 
Published: November 2015

Abstract
Security has emerged as the most concerned aspect of cloud computing environment and a prime challenge for the cloud users. The stored data can be retrieved by the user whenever and wherever required. But there is no guarantee that the data stored in the cloud server has not been accessed by any unauthorized user. The current cloud framework does not allow encrypted data to be stored due to the space and storage cost. Storing secret data in an unencrypted form is vulnerable to external attacks by both illegitimate customers and a Cloud Service Provider (CSP). Traditional encryption techniques require more computation and storage space. Hence, protecting cloud data with minimal computations is the prime task. Secured Document Sharing Using Visual Cryptography (SDSUVC) technique proposes an efficient storage scheme in a cloud for storing and retrieving a document file without any mathematical computations and also ensures data confidentiality and integrity.

Published: November 2015

Abstract
Fruits of several, mainly Polish cultivars of floricane- and primocane-fruiting red raspberry (Rubus idaeus), black raspberry (Rubus occidentalis) and blackberry (Rubus fruticosus), grown in central Europe during two successive vegetation periods, were investigated. The content of phenolic compounds, including anthocyanins, as well as antioxidant properties of fruit extracts were analysed. A number of methods were employed: ferric ion reducing antioxidant power (FRAP), cupric ion reducing antioxidant capacity (CUPRAC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity involving both colorimetric and EPR spectrometric measurements. From among all the tested fruits black raspberries had the largest antioxidant capacity as verified by all methods used in this study. These berries were also the most abundant in phenolic and anthocyanin compounds. Blackberries were characterised by larger antioxidant capacity than red raspberry fruits which were accompanied by higher content of total phenolics and anthocyanins. Berries of primocane-fruiting cultivars, often used for intensive agricultural production, generally did not differ in the total phenolic and anthocyanin content as well as in the antioxidant capacity as compared to the traditional, floricane-fruiting ones. The research contributes to deep characterisation of central European berry fruits which due to their high content and large diversity of health-beneficial compounds are classified as natural functional food.
Poly(butyl cyanoacrylate) nanoparticles stabilised with poloxamer 188: particle size control and cytotoxic effects in cervical carcinoma (HeLa) cells

Published: November 2015

AbstractIn this study, the preparation of poloxamer 188-coated poly(butyl cyanoacrylate) colloidal nanospheres of controlled size distribution and their physicochemical characterisation were investigated and their cytotoxic effects in cervical carcinoma (HeLa) cells evaluated. The nanoparticles were prepared by controlled emulsion polymerisation of butyl cyanoacrylate in an aqueous medium containing poloxamer 188 as an amphiphilic non-ionic colloidal stabiliser. The colloids thus obtained were characterised by scanning electron microscopy, dynamic and electrophoretic light-scattering, Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR) spectroscopy. The average size of the particles could be finely controlled within an interval between 220 nm and 290 nm by varying the concentration of the precursor and citric acid in the polymerisation medium. The particle zeta-potentials in phosphate-buffered saline were approximately -4.5 mV. FTIR and NMR data confirmed the expected composition of nanoparticles and the complete precursor polymerisation. In-vitro studies with cervical carcinoma (HeLa) cells demonstrated the dose-dependent cytotoxicity of nanoparticles (IC50 ≈ 30 μg mL
Comparison of seismic sources for shallow seismic: sledgehammer and pyrotechnics
Authors: Brom Aleksander , Stan-Kłeczek Iwona 
Published: November 2015

AbstractThe pyrotechnic materials are one of the types of the explosives materials which produce thermal, luminous or sound effects, gas, smoke and their combination as a result of a self-sustaining chemical reaction. Therefore, pyrotechnics can be used as a seismic source that is designed to release accumulated energy in a form of seismic wave recorded by tremor sensors (geophones) after its passage through the rock mass. The aim of this paper was to determine the utility of pyrotechnics for shallow seismic engineering. The work presented comparing the conventional method of seismic wave excitation for seismic refraction method like plate and hammer and activating of firecrackers on the surface. The energy released by various sources and frequency spectra was compared for the two types of sources. The obtained results did not determine which sources gave the better results but showed very interesting aspects of using pyrotechnics in seismic measurements for example the use of pyrotechnic materials in MASW.

The teacher is an employee of the educational establishment, having qualified for the teaching and education of their students. In addition, in accordance with the Teacher Card, he is obliged to conscientiously carry out the tasks of teaching and educational and charitable. Teacher will call the person responsible for the conduct and coordination of work in the classroom. His job is to get to know the students and their social conditions, cooperation with parents, ensuring socio-moral attitudes, health and the organization of care and support in individual cases. The teacher educator could feel the satisfaction of relevant professional work, enjoy his progress in many areas of development, as well as the appropriate contact with parents and legal guardians must meet specific conditions relating to his personality. Emotional involvement of the teacher, his serenity, creativity and openness to children and young people, as well as their parents, triggers analogous reactions, that is, a positive attitude and the need for cognitive activity.
Women – Home Educators
Authors: Kochan Katarzyna 
Published: November 2015

Abstract
Homeschooling as an alternative form of education children in Poland, is becoming more popular. Over the past 20 years, the number of homeschooled children in the h in Poland has increased from a few to about three thousand. There is little research on this phenomenon. Until now only two books have been published - first by M. Budajczak and the second by M. P. Zakrzewski. There is, therefore, a need for further scientific exploration of homeschooling. As women are the ones who are mostly involved in homeschooling, even it they are helped by men, it seems to be interesting to describe a contemporary Polish home teaching women.
Health and Health Care of Medicare Beneficiaries in 2030

Published: November 2015

Abstract
On Medicare’s 50th anniversary, we use the Future Elderly Model (FEM) – a microsimulation model of health and economic outcomes for older Americans – to generate a snapshot of changing Medicare demographics and spending between 2010 and 2030. During this period, the baby boomers, who began turning 65 and aging into Medicare in 2011, will drive Medicare demographic changes, swelling the estimated US population aged 65 or older from 39.7 million to 67.0 million. Among the risks for Medicare sustainability, the size of the elderly population in the future likely will have the highest impact on spending but is easiest to forecast. Population health and the proportion of the future elderly with disabilities are more uncertain, though tools such as the FEM can provide reasonable forecasts to guide policymakers. Finally, medical technology breakthroughs and their effect on longevity are most uncertain and perhaps riskiest. Policymakers will need to keep these risks in mind if Medicare is to be sustained for another 50 years. Policymakers may also want to monitor the equity of Medicare financing amid signs that the program’s progressivity is declining, resulting in higher-income people benefiting relatively more from Medicare than lower-income people.
