Coronary heart disease is a major public health problem worldwide and firefighters may be at particular occupational risk. In a cross-sectional study in Ras Laffan Industrial City, Qatar, we assessed the 10- year risk of coronary heart disease events for 369 Qatar Petroleum staff at their periodic medical examination. The subjects of the study (all males) were divided into firefighters and non-firefighters groups. Based on the Framingham risk score calculations, 69.9% of the subjects were categorized as low risk, 27.1% as intermediate risk and 2.9% as high risk. None of the firefighters was categorized as high risk, 15.5% were intermediate and the rest were low risk. In the whole group, low high-density lipoprotein cholesterol was the most prevalent risk factor (68.8%), followed by hypertension (32.0%) and smoking (15.4%). The mean risk of developing coronary heart disease in firefighters [6.5% (SD 3.7%)] was significantly lower than in non-firefighters [9.5% (SD 6.5%)]. Source

Research in Social and Administrative Pharmacy
Background: Much of the migrant workforce in Qatar is of low literacy level and does not understand Arabic or English, presenting a significant challenge to health care professionals. Medicine labels are typically in Arabic and English and are therefore poorly understood by these migrant workers. Objective: To develop pictograms illustrating selected medicine label instructions and to evaluate comprehension of the pictograms or conventional text supported with verbal instructions in foreign workers with low literacy skills. Methods: A range of common labeling instructions were identified and pictograms depicting these were developed using visual concepts and ideas from the literature. The process involved a consultative approach with input from the researchers, a local graphic artist, and members of the target population. The final set was evaluated for comprehension in participants who were randomized to one of three study groups: text plus verbal instructions, pictogram-only label, and pictogram with verbal instructions. One-way ANOVA and Chi-square tests were used to assess differences between group variables. Statistical significance was set at P≤0.05. Results: Of 23 label instructions screened, 11 were selected for the study. A total of 123 participants took part in this study. Pictogram plus verbal instructions group achieved better results in interpreting the majority of the label instructions (P≤0.05). The best interpreted pictograms with verbal instructions included: "Take two tablets three times a day," "Take one tablet in the morning and one tablet at night," and "Instill one drop in the eye." The worst interpreted pictograms with verbal instructions were: "Do not take with dairy products" and "Do not use by mouth." Some pictograms were difficult to interpret even when accompanied with verbal instructions, suggesting the need to thoroughly pilot them among users prior to implementation. Conclusion: Medication labels consisting of simple pictorials supported by verbal instructions were better comprehended by individuals with low literacy skills than labels with written plus verbal instructions in a language that the individual did not understand. Further, pictogram-only labels were the least comprehended types of medicine labels among the participants. © 2014 Elsevier Inc. Source

SPE Drilling and Completion
Although drilling technology is now able to deliver ultra long horizontal wells (LHWs), completion technology has been slower to evolve. Running long liners, effective stimulation, and completions are some of the areas that require more attention. This paper discusses some of the challenges in the development of the Al Shaheen reservoirs offshore Qatar and how they were overcome. Some of these wells have a stepout in excess of 30,000 ft with a total vertical depth of 3,100 to 3,500 ft, and thus, they offer some unique challenges. Running and cementing liners to these depths is difficult, and some of the methods to achieve this effectively are discussed. Perforating guidelines are presented that allow sand control without having to resort to conventional sand-control practices. Stimulation of such long reservoir sections is a particular challenge, and a fine balance must be struck between acid coverage and cost, both for barefoot and perforated intervals. The so-called Q-CAJ technique of acid distribution, which has allowed acceptable stimulation despite these conditions, is presented. The technique also offers opportunities to stimulate long horizontal boreholes more effectively and at lower cost. Some of the wells are completed with multizone selective completions, which push the design limit of equipment. A number of such intelligent wells have been completed successfully, and more aggressive wells are planned. To optimize the development cost, dual-lateral wells have also been drilled with complete control over each lateral. Discussed are some of the underlying completion techniques such as running completion in stages, use of mechanical latches, hydraulic-control-line wet connects, interval control valves, and limitations imposed by control lines. The paper concludes with some of the challenges that have yet to be overcome. © 2010 Society of Petroleum Engineers. Source

Schlumberger engineers are working to integrate corrosion measurement data gathering into overall field operations. The Petrel E&P software platform provides operators and service companies with a reservoir level view of field optimization by allowing asset teams to build collaborative workflows based on geomechanical, geochemical and reservoir fluid properties. The Techlog wellbore software platform further advances this evaluation by providing wellbore-centered workflows to identify corrosion risks. The Avocet production operations software platform combines well operations and production data management systems to deliver a clear and comprehensive picture of operations at the surface. The software flags those areas with higher corrosion rates or a history of corrosion-related events, and as a result, the operator can prioritize corrosion mitigation efforts and implement suitable preventive measures.
