Andreeva Bay in northwest Russia hosts one of the former coastal technical bases of the Northern Fleet. Currently, this base is designated as the Andreeva Bay branch of Northwest Center for Radioactive Waste Management (SevRAO) and is a site of temporary storage (STS) for spent nuclear fuel (SNF) and other radiological waste generated during the operation and decommissioning of nuclear submarines and ships. According to an integrated expert evaluation, this site is the most dangerous nuclear facility in northwest Russia. Environmental rehabilitation of the site is currently in progress and is supported by strong international collaboration. This paper describes how the optimization principle (ALARA) has been adopted during the planning of remediation work at the Andreeva Bay STS and how Russian-Norwegian collaboration greatly contributed to ensuring the development and maintenance of a high level safety culture during this process. More specifically, this paper describes how integration of a system, specifically designed for improving the radiological safety of workers during the remediation work at Andreeva Bay, was developed in Russia. It also outlines the 3D radiological simulation and virtual reality based systems developed in Norway that have greatly facilitated effective implementation of the ALARA principle, through supporting radiological characterisation, work planning and optimization, decision making, communication between teams and with the authorities and training of field operators.
The intraocular pressure reducing effect and side-effects of latanoprost, a phenyl-substituted prostaglandin analogue, were compared with those of timolol, in a group of 31 glaucomatous or ocular hypertensive patients, divided into three subgroups. The study was randomized and double masked. At the end of 6 month's treatment with latanoprost 0.005% once daily, either as a morning dose or as an evening dose, there was a reduction in intraocular pressure of 33% (p
PURPOSE: To evaluate safety, efficacy, predictability, and stability in the treatment of myopic astigmatism with laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) using the 200 Hz flying-spot technology of the LaserSight LSX excimer laser. SETTING: SynsLaser Clinic, Tromsø, Norway. METHODS: This retrospective study included 110 eyes treated with LASIK and 87 eyes treated with PRK that were available for evaluation at 6 and 12 months, respectively. The mean preoperative spherical equivalent (SE) was -5.35 diopters (D) +/- 2.50 (SD) (range -1.13 to -11.88 D) in the LASIK eyes and -4.72 +/- 2.82 D (range -1.00 to -15.50 D) in the PRK eyes. The treated cylinder was 4.00 D in both groups. Eleven (8.5%) LASIK eyes and 8 (7.4%) PRK eyes had secondary surgical procedures before 6 and 12 months, respectively, and were excluded when the 6 and 12 month outcomes were analyzed. RESULTS: None of the eyes lost 2 or more lines of best spectacle-corrected visual acuity. Seventy-seven percent of the LASIK eyes and 78% of the PRK eyes achieved an uncorrected visual acuity of 20/20 or better; 98% in both groups achieved 20/40 or better. The SE was within +/-0.5 D of the desired refraction in 83% of the LASIK eyes and 77% of the PRK eyes; it was within +/-1.0 D in 97% and 98%, respectively. The cylinder correction had a mean magnitude of error of 0.04 +/- 0.31 D (range -0.96 to +0.85 D) in the LASIK eyes and 0.02 +/- 0.37 D (range -1.44 to +0.72 D) in the PRK eyes. Refractive stability was achieved at 1 month and beyond in the LASIK eyes and at 3 months and beyond in the PRK eyes. CONCLUSION: The outcomes of this study are comparable to those achieved with lasers that use small-beam technology with a lower frequency, as well as with other types of delivery systems. They suggest that the 200 Hz technology used in the LaserSight LSX excimer laser is safe, effective, and predictable and that with LASIK and PRK the results are stable when treating low to moderate myopia and astigmatism up to 4.0 D.
The Alaska Department of Health and Social Services implemented the Behavioral Risk Factor Surveillance System (BRFSS) in 1990 in
cooperation with the federal Centers for Disease Control and Prevention. The system gathers information about the health-related lifestyle choices of Alaskan adults related to leading causes of death such as heart disease, cancer and injury. The program is part of an ongoing national data collection system. Results are analyzed each year to improve our understanding of Alaskan
health habits and to measure progress toward national and state health objectives. This report summarizes survey findings from
1991 to 1996 and compares the results to selected national health objectives presented in the Healthy People 2000 publication.
Behavior and lifestyle play an important part in determining our
health status and lifespan. Every day Alaskans make lifestyle choices that profoundly affect their health. Although heredity and environment play a part, the leading causes of death in Alaska (heart disease, cancer and unintentional injuries) are closely related to lifestyle factors. Lifestyle and behavioral factors that affect health include such things as diet, exercise, use of alcohol and
tobacco, and preventive health practices. Many premature deaths
and disabilities could be prevented through better control of these
behavioral risk factors.
The implementation of work hour restrictions across North America have resulted in decreased levels of self injury and medical errors for Residents. An arbitration ruling in Quebec has led to further curtailment of work hours beyond that proposed by the ACGME. This may threaten Resident quality of life and in turn decrease the educational quality of surgical residency training.
We administered a quality of life questionnaire with an integrated education quality assessment tool to all General Surgery residents training at McGill 6 months after the work hour restrictions.
Across several strata respondents reveal a decreased sense of educational quality and quality of life.
The arbitration argued that work- hour restrictions would be necessary to improve quality of life for trainees and hence improve patient safety. Results from this study demonstrate the exact opposite in a large majority of respondents, who report a poorer quality of life and a self-reported inability on their part to provide continuous and safe patient care.
In article are given substantiation for modification of contemporary list of biologically active substances with undesirable toxicological qualities (namely included in this list of menthofuran, methyleugenol (4-Allyl-1,2-dimethoxybenzene), teucrin A, capsaicin, estragol1 (-Allyl-4-methoxybenzene) and excluded from the list of quinine, santonin, berberin) and developing the list of plants--natural sources of flavourings substances. The new criteria of European Union for including into the relevant for using in/on foodstuff list of flavouring substances, which was published in the Comission Implementing Regulation (EU) No 872/2012 concerning flavourings, listed the 11 flavouring substances for which have been established indexes of foodstuffs in manufacturing, which there are could using and criteria of their safety (caffeine, theobromine, neohesperidin dihydrocalcone, rebaudioside A, d-camphor, three quinine salts (FL 14.011, FL 14.152 and FL 14.155), glycyrrhizic acid and its ammoniated form, ammonium chloride, discussed the possibility of using R- and S-isomers of flavouring substances and L- and D-forms of aminoacids for preparing of flavours, are discussed. Improving of the system of safety using of flavourings in Russian Federation, harmonized with demands of European Union and FAQ/WHO, are, at first, connected with the necessity of reevaluation of the list flavouring substances, which could be use in/on foodstuff, developing of list of the plants--natural sources of flavourings substances and preparations and regulations of using flavourings preparations which can include biologically active substances.
