An exploration of sharps injuries within healthcare students at a UK university
Background: There is evidence available worldwide that nursing, medical and dental students sustain sharps injuries during their programmes of study. However, there is lack of evidence and research relating to the many students of other healthcare professions who may encounter sharps instruments. Aim/objective: The aim of the study was to identify the extent, type and impact of sharps injuries sustained by pre-registration healthcare students. Methods: An online survey was administered to 3372 healthcare students at a University in the United Kingdom. Findings/results: Some healthcare students other than nursing, medical and dentistry had sustained a sharps injury. The most common device involved were glass ampoules. The common causes were equipment and carelessness. Some healthcare students sustained psychological impacts following the sharps injury. Discussion: Sharps injuries are common amongst some healthcare students and there is scope for more education for these groups of students relating to the risks, safe handling, reporting and prevention of sharps injuries
Az amurgéb (Perccottus glenii Dybowski, 1877) egy álló- és egy folyóvízi populációjának táplálkozásökológiai vizsgálata
Az utóbbi két évtizedben a Távol‐Keletről származó amurgéb (Perccottus glenii) inváziója figyelhető meg Kelet‐ és Közép‐Európában. Munkánk során az amurgéb évszakonkénti részletes táplálkozásökológiai elemzését tűztük ki célul egy állóvízben (a Rakamaz-Tiszanagyfalui‐Nagy‐morotvában) és egy vízfolyásban (a Lónyay‐főcsatornában). A legjelentősebb táplálékszervezeteknek az árvaszúnyogok (Chironomidae), szitakötők (Odonata), rákok (Crustacea) és kérészek (Ephemeroptera) bizonyultak. A faj táplálkozásának intenzitásában nem tapasztalható méret, évszak és hely által befolyásolt változás. Táplálékának összetételét legfőképp a halak mérete befolyásolja, amelynek hatása erősebbnek bizonyult az élőhelyi és évszakos hatásoknál is. Kutatásaink igazolják, hogy az amurgé a vízi táplálékhálózat számos szintjét (kompartmentjét) befolyásolhatja, elsősorban azonban a makroszkopikus gerinctelen szervezetek hatékony predátora
Urban Pluvial Flood Risk in Romania, in the Context of Floods Directive Implementation
Romania is a flood prone country and same are her cities. Pluvial floods can occur in urban or rural areas without a direct connection with river or a water body. As part of the Floods Directive implementation, Romania has identified, in the first cycle, a number of 17 urban areas with a significant pluvial flood risk potential. For every urban area identified, flood hazard and flood risk maps have been developed. Based on this, the present paper tries to present some of the main risk receptors, that could give an insight related to the level of risk at which the urban areas are exposed. What is the quantitative risk profile of this cities, what can be done further to mitigate this risk and are there any other urban areas at risk of pluvial flooding? The present paper seeks to provide an answer at the above questions and present potential solutions for pluvial risk reduction
Comparison of Rhodotorula sp. and Bacillus megaterium in the removal of cadmium ions from liquid effluents
This study compares the capacity of Rhodotorula sp. and Bacillus megaterium for Cd(II) removal considering the influence of operating parameters (pH, biosorbent dosage, contact time, temperature, initial metal concentration in solution). The highest Cd(II) uptake of 14.2 mg/g by Rhodotorula sp. was exhibited at 30°C, when working at pH 6 and with 5 g/l biosorbent dosage, after 48 h of contact time. In these conditions, a removal efficiency of 85% was obtained. Similar outcomes were obtained for B. megaterium (15.1 mg/g, 90%) at 35°C, pH 4 and 3 g/l biosorbent dosage, considered as the optimum set of parameters, equilibrium being achieved for a contact time of 20 min. The possible interaction mechanisms between the biosorbents and Cd(II) were evaluated through point of zero charge (pHpzc), Fourier transform infrared (FTIR), spectroscopy and scanning electron microscopy coupled with energy dispersive X-ray microanalysis (SEM-EDX). Data were modeled using pseudo-first and pseudo-second order kinetic models and Langmuir and Freundlich isotherms models. Further studies considered a modeling approach based on linear regression with Durbin-Watson statistics, while the accuracy and precision of experiments were evaluated by ANOVA.This work was supported by two grants

Search for Bremsstrahlung radiation in quasi-free n p --> n p gamma reactions
Due to the high sensitivity of the N N --> N N gamma reaction to the
nucleon-nucleon potential, Bremsstrahlung radiation is used as a tool to
investigate details of the nucleon-nucleon interaction. Such investigations can
be performed at the cooler synchrotron COSY in the Research Centre Juelich, by
dint of the COSY-11 detection system. The results of the identification of
Bremsstrahlung radiation emitted via the d p --> d p gamma reaction in data
taken with a proton target and a deuteron beam are presented and discussed.Comment: 3 pages; Presented at Meson 2004: 8th International Workshop on Meson

abcese pulmonare cronice. Pentru un număr redus de pacienți cu comorbidități severe asociate sau disfuncții respiratorii aceste
operații nu sunt indicate. Am analizat eficiența lambourilor musculare pentru a corecta cavitățile reziduale.
Material și metode: Am studiat pacienți cu scor de risc ASA >3, cu FEV si FVC<40, clasa NYHA mai mare sau egală cu II. Am inclus
în studiu pacienți cu empiem (1caz), aspergiliom (8 cazuri), abces pulmonar cronic (1 caz) .Am folosit diverse lambouri musculare
pentru a umple cavitățile. Pentru pacienții cu aspergilom am practicat toracotomie, cavernotomie, excizia micetomului, sutura fistulei.
Am folosit lambouri din pectoralul mare (2), muşchii intercostali (4) şi dorsal mare (2). Pentru pacienții cu supurații cronice pulmonare
am folosit dorsal mare, iar pentru empiem am asociat şi muşchi pectoral mare, trapez şi intercostal cu toracoplastie.
Rezultate: Evoluția imediată a fost favorabilă în toate cazurile cu excepția unuia care a necesitat reintervenție pentru sângerare. Un
pacient a dezvoltat serom. În toate cazurile, viabilitatea lamboului nu a fost afectată. Nu s-au inregistrat decese.
Concluzii: Scopul acestor intervenții a fost sa eliminăm spațiile libere din pleură sau plămân. Pentru pacienții tarați, decorticările
şi rezecțiile sunt operații riscante, această nouă abordare fiind benefică. Evoluția favorabilă, morbiditatea minimă după folosirea
lambourilor musculare justifică deplin acest procedeu. Chiar dacă numărul mic de cazuri în care am practicat acest tip de operație ne
limitează pentru moment spectrul de experiență, rezultatele pozitive sunt încurajatoare.Introduction: The surgical treatment of residual space for patients with empyema or chronic lung abscess is in most cases decortication
or lung resection. For a limited number of patients with severe comorbidities or respiratory dysfunction these procedures are prohibited.
We analyzed the efficiency of muscle flaps to solve the residual cavities these patients.
Material and methods: We studied patients with ASA risk > 3, with FEV and FVC < 40%, NYHA II or more. Patients with empyema
(1 case), aspergilloma (8 cases), chronic lung abscess (1 case) were included in the study. Different types of muscle flaps were used
to fill the cavities. For patients with aspergilloma we performed thoracotomy, cavernotomy, excision of the micetoma, fistulae suture;
muscles used: pectoris major – 2, intercostal – 4 and latissimus dorsi – 2. For the patient with chronic suppuration of the lung we used
latissimus, and for the empyema we associated pectoris major, trapezius and intercostal muscle with thoracoplasty.
Results: The immediate outcome was favorable in all cases except one who required exploration for bleeding. One patient developed
wound seroma. In all cases the viability of the transposed muscle was not affected. We recorded no mortality.
Conclusions: The aim of surgery is to eliminate all empty space in the pleura or lung. For impaired patients decortication or resection
are very risky, thus new approach was needed. The good outcome, minimal morbidity after using muscle flaps, fully justify their use.
The low number of patients limits our experience, but the good results are encouraging
Study of dielectron production in C+C collisions at 1 AGeV
The emission of e+e- pairs from C+C collisions at an incident energy of 1 GeV
per nucleon has been investigated. The measured production probabilities,
spanning from the pi0-Dalitz to the rho/omega! invariant-mass region, display a
strong excess above the cocktail of standard hadronic sources. The
bombarding-energy dependence of this excess is found to scale like pion
production, rather than like eta production. The data are in good agreement
with results obtained in the former DLS experiment.Comment: submitted to Physics Letters
The ASY-EOS experiment at GSI: investigating the symmetry energy at supra-saturation densities
The elliptic-flow ratio of neutrons with respect to protons in reactions of
neutron rich heavy-ions systems at intermediate energies has been proposed as
an observable sensitive to the strength of the symmetry term in the nuclear
Equation Of State (EOS) at supra-saturation densities. The recent results
obtained from the existing FOPI/LAND data for Au+Au collisions
at 400 MeV/nucleon in comparison with the UrQMD model allowed a first estimate
of the symmetry term of the EOS but suffer from a considerable statistical
uncertainty. In order to obtain an improved data set for Au+Au collisions and
to extend the study to other systems, a new experiment was carried out at the
GSI laboratory by the ASY-EOS collaboration in May 2011.Comment: Talk given by P. Russotto at the 11th International Conference on

Connection between Telomerase Activity in PBMC and Markers of Inflammation and Endothelial Dysfunction in Patients with Metabolic Syndrome
Metabolic syndrome (MS) is a constellation of metabolic derangements associated with vascular endothelial dysfunction and oxidative stress and is widely regarded as an inflammatory condition, accompanied by an increased risk for cardiovascular disease. The present study tried to investigate the implications of telomerase activity with inflammation and impaired endothelial function in patients with metabolic syndrome. Telomerase activity in circulating peripheral blood mononuclear cells (PBMC), TNF-α, IL-6 and ADMA were monitored in 39 patients with MS and 20 age and sex-matched healthy volunteers. Telomerase activity in PBMC, TNF-α, IL-6 and ADMA were all significantly elevated in patients with MS compared to healthy volunteers. PBMC telomerase was negatively correlated with HDL and positively correlated with ADMA, while no association between TNF-α and IL-6 was observed. IL-6 was increasing with increasing systolic pressure both in the patients with MS and in the healthy volunteers, while smoking and diabetes were positively correlated with IL-6 only in the patients' group. In conclusion, in patients with MS characterised by a strong dyslipidemic profile and low diabetes prevalence, significant telomerase activity was detected in circulating PBMC, along with elevated markers of inflammation and endothelial dysfunction. These findings suggest a prolonged activity of inflammatory cells in the studied state of this metabolic disorder that could represent a contributory pathway in the pathogenesis of atherosclerosis
