Designing a customized clinical practice guideline regarding antibiotic prophylaxis for Iranian general dentists.

BACKGROUND: Clinical practice guidelines produced by developed countries seemed to be not completely feasible for developing countries due to their different local context. In this study, we designed a customized guideline about antibiotic prophylaxis before dental procedures for Iranian general dentists. METHODS: This study was conducted of two parts, including a qualitative part and a cross-sectional analytic part. A multidisciplinary team searched for related guidelines and other documents, selected the most updated and high quality ones, customized their recommendations based on available antibiotics in Iran, prepared a draft adapted guideline and summarized its recommendations in 3 flowcharts. An expert panel (20 specialists of four Iranian dental universities) participated in a consensus process, afterwards to determine the relevance and clarity of the flowcharts and their items. Then the Content Validity Indices (CVIs) were calculated and any items with CVI higher than 0.79 remained. RESULTS: The adapted recommendations were summarized in flowcharts A to C. Two separate groups of patients who need antibiotic prophylaxis were presented in flowchart A; including those with high risk for distant-site infection (infective endocarditis and prosthetic joint infection) and those at risk for poor healing and orofacial infection (due to impaired immunologic function). Flowcharts B and C described antibiotic regimen and also the dental procedures where antibiotic prophylaxis was needed for mentioned groups. The content validity indices and the percentages of agreement between the expert panel members were considerably high. CONCLUSIONS: A localized, clear and straight forward guideline that addresses all groups of dental patients who need antibiotic prophylaxis has been produced for Iranian general dentists

MBSPDiscover: An Automatic Benchmark for MultiBSP Performance Analysis

International audienceMulti-Bulk Synchronous Parallel (MultiBSP) is a recently proposed parallel programming model for multicore machines that extends the classic BSP model. MultiBSP is very useful to design algorithms and estimate their running time, which are hard to do in High Performance Computing applications. For a correct estimation of the running time, the main parameters of the MultiBSP model for different multicore architectures need to be determined. This article presents a benchmark proposal for measuring the parameters that characterize the communication and synchronization cost for the model. Our approach discovers automatically the hierarchical structure of the multicore architecture by using a specific tool (hwloc) that allows obtaining runtime information about the machine. We describe the design, implementation and the results of benchmarking two multicore machines. Furthermore, we report the validation of the proposed method by using a real MultiBSP implementation of the vector inner product algorithm and comparing the predicted execution time against the real execution time

Experimental Investigations of Alpha Particle Irradiation of Natural Nickel

Attempts have been made to measure the activity in irradiated natural Ni material induced by α-particles in the energy range 10-40 MeV followed by stack foil activation technique. Activity induced has been determined through the cross-sections obtained from various reactions for 58Ni(α, p)61Cu, 58Ni(α,  pn)60Cu, 60Ni(α, p2n)61Cu, 60Ni(α, n)63Zn, 60Ni(α, 2n)62Zn,61Ni(α, 3n)62Zn and 61Ni(α, 2n)63Zn in α+natNi interaction at different beam energies has been found to vary from 10-26 microns

Frequency and clinical patterns of stroke in Iran - Systematic and critical review

<p>Abstract</p> <p>Background</p> <p>Cerebrovascular disease is the second commonest cause of death, and over a third of stroke deaths occur in developing countries. To fulfil the current gap on data, this systematic review is focused on the frequency of stroke, risk factors, stroke types and mortality in Iran.</p> <p>Methods</p> <p>Thirteen relevant articles were identified by keyword searching of PubMed, Iranmedex, Iranian University index Libraries and the official national data on burden of diseases.</p> <p>Results</p> <p>The publication dates ranged from 1990 to 2008. The annual stroke incidence of various ages ranged from 23 to 103 per 100,000 population. This is comparable to the figures from Arab Countries, higher than sub-Saharan Africa, but lower than developed countries, India, the Caribbean, Latin America, and China. Similarly to other countries, ischaemic stroke was the commonest subtype. Likewise, the most common related risk factor is hypertension in adults, but cardiac causes in young stroke. The 28-day case fatality rate is reported at 19-31%.</p> <p>Conclusions</p> <p>Data on the epidemiology of stroke, its pattern and risk factors from Iran is scarce, but the available data highlights relatively low incidence of stroke. This may reflect a similarity towards the neighbouring nations, and a contrast with the West.</p

Algebraic Approach to Exact Solution of the (2 + 1)-Dimensional Dirac Oscillator in the Noncommutative Phase Space

We study the (2 + 1)-dimensional Dirac oscillator in the noncommutative phase space and the energy eigenvalues and the corresponding wave functions of the system are obtained through the sl(2) algebraization. It is shown that the results are in good agreement with those obtained previously via a different method

Pattern of tobacco use among primary school teachers in Belgaum city, India – A Cross Sectional Study

Introduction The consumption of tobacco related products by the school teachers is a bad habit because it sends a wrong signal to young minds of students. It is injurious to health and is a waste of money and also is a wrong role model for the students.Objectives To find out the prevalence of pattern of tobacco use among primary school teachers in Belgaum city and to determine the factors influencing the use of tobacco among primary school teachers.Methods A cross-sectional study was conducted using random sampling technique among 400 teachers aged 21 to 60 years from 78 primary schools in Belgaum city during March to December 2009.Results Overall, prevalence of any form of tobacco use among primary school teachers was 14.50%. Only male teachers 46.03% used tobacco. 37.93% were using smoking type of tobacco, 46.56% used smokeless & 15.51%were using both types of tobacco products. Most of the users initiated tobacco use by 16 to 20 years of age. A substantial number of teachers initiated tobacco use for fun, imitation and peer pressure. 58.33% of the teachers were using tobacco due to un-satisfaction from profession, 37.50% due to family problems.Conclusion High proportion of male teachers used tobacco than female teachers, because of social norm. Almost all the teachers consciously avoided tobacco use in school premises. Students will be encouraged to start using tobacco, if they observe use of tobacco products by teachers who are the role models for students. It was concluded that it would be beneficial to conduct educational programs and seminars encouraging tobacco cessation to this professional group, along with school children
