    Washington Pension System Review

    The purpose of this study is to analyze the incidence of Total Permanent Disability (TPD)pensions in Washington State's workers' compensation program. Concerns exist at both thelegislature and in the Department of Labor and Industries as there appears to have been a sharp upturn in the number of pensions awarded since late in the 1990s. This report examines the factors that may be causally related to any upsurge in such awards. Our task is to evaluate pension incidence for both the state fund and the self-insured populations, with a view towards identifying causes of the trend in both sectors, although we concentrate more on the state fund Cclaims due to data limitations

    A global perspective on marine photosynthetic picoeukaryote community structure

    A central goal in ecology is to understand the factors affecting the temporal dynamics and spatial distribution of microorganisms and the underlying processes causing differences in community structure and composition. However, little is known in this respect for photosynthetic picoeukaryotes (PPEs), algae that are now recognised as major players in marine CO2 fixation. Here, we analysed dot blot hybridisation and cloning–sequencing data, using the plastid-encoded 16S rRNA gene, from seven research cruises that encompassed all four ocean biomes. We provide insights into global abundance, α- and ÎČ-diversity distribution and the environmental factors shaping PPE community structure and composition. At the class level, the most commonly encountered PPEs were Prymnesiophyceae and Chrysophyceae. These taxa displayed complementary distribution patterns, with peak abundances of Prymnesiophyceae and Chrysophyceae in waters of high (25:1) or low (12:1) nitrogen:phosphorus (N:P) ratio, respectively. Significant differences in phylogenetic composition of PPEs were demonstrated for higher taxonomic levels between ocean basins, using Unifrac analyses of clone library sequence data. Differences in composition were generally greater between basins (interbasins) than within a basin (intrabasin). These differences were primarily linked to taxonomic variation in the composition of Prymnesiophyceae and Prasinophyceae whereas Chrysophyceae were phylogenetically similar in all libraries. These data provide better knowledge of PPE community structure across the world ocean and are crucial in assessing their evolution and contribution to CO2 fixation, especially in the context of global climate change

    Meat and Nicotinamide:A Causal Role in Human Evolution, History, and Demographics

    Get PDF
    Hunting for meat was a critical step in all animal and human evolution. A key brain-trophic element in meat is vitamin B 3 /nicotinamide. The supply of meat and nicotinamide steadily increased from the Cambrian origin of animal predators ratcheting ever larger brains. This culminated in the 3-million-year evolution of Homo sapiens and our overall demographic success. We view human evolution, recent history, and agricultural and demographic transitions in the light of meat and nicotinamide intake. A biochemical and immunological switch is highlighted that affects fertility in the ‘de novo’ tryptophan-to-kynurenine-nicotinamide ‘immune tolerance’ pathway. Longevity relates to nicotinamide adenine dinucleotide consumer pathways. High meat intake correlates with moderate fertility, high intelligence, good health, and longevity with consequent population stability, whereas low meat/high cereal intake (short of starvation) correlates with high fertility, disease, and population booms and busts. Too high a meat intake and fertility falls below replacement levels. Reducing variances in meat consumption might help stabilise population growth and improve human capital

    Evaluation of calcium lignosulfonate as a acceptable previous cargo for edible fats and oils

    Shipping of edible fats and oils into Europe is permitted in bulk tanks, provided that the previous cargo is included in a positive list. The European Commission requested EFSA to evaluate the acceptability of calcium lignosulfonate as previous cargo for fats and oils. The evaluation was based on the same criteria as those used for the evaluation of the substances currently on the list in the Annex to Commission Directive 96/3/EC as a acceptable previous cargoes for edible fats and oils. In 2017, the EFSA Panel on Contaminants in the Food Chain (CONTAM Panel) concluded that calcium lignosulfonate did not meet the acceptability criteria, due to uncertainties as regards the composition and toxicity of its low-molecular weight fraction (LMWF) below 1,000 Da. In the current evaluation, new information, showing lack of genotoxicity of the LMWF isolated from a technical grade of calcium lignosulfonate was provided. Due to uncertainties regarding the presence of lignosulfonate components below 200 Da in this LMWF tested for genotoxicity, the CONTAM Panel concluded that the information provided was insufficient to assess the acceptability of calcium lignosulfonate as previous cargo. The Panel recommends a better analysis of the LMWF and a new genotoxicity test using this LMWF, including components < 200 Da, and evidence that the tested material is representative of the LMWF in products intended to be shipped as previous cargo for edible fat and oils.</p

    Update of the risk assessment of mineral oil hydrocarbons in food

    Abstract Mineral oil hydrocarbons (MOH) are composed of saturated hydrocarbons (MOSH) and aromatic hydrocarbons (MOAH). Due to the complexity of the MOH composition, their complete chemical characterisation is not possible. MOSH accumulation is observed in various tissues, with species‐specific differences. Formation of liver epithelioid lipogranulomas and inflammation, as well as increased liver and spleen weights, are observed in Fischer 344 (F344) rats, but not in Sprague–Dawley (SD) rats. These effects are related to specific accumulation of wax components in the liver of F344 rats, which is not observed in SD rats or humans. The CONTAM Panel concluded that F344 rats are not an appropriate model for effects of MOSH with wax components. A NOAEL of 236 mg/kg body weight (bw) per day, corresponding to the highest tested dose in F344 rats of a white mineral oil product virtually free of wax components, was selected as relevant reference point (RP). The highest dietary exposure to MOSH was estimated for the young population, with lower bound–upper bound (LB–UB) means and 95th percentiles of 0.085–0.126 and 0.157–0.212 mg/kg bw per day, respectively. Considering a margin of exposure approach, the Panel concluded that the present dietary exposure to MOSH does not raise concern for human health for all age classes. Genotoxicity and carcinogenicity are associated with MOAH with three or more aromatic rings. For this subfraction, a surrogate RP of 0.49 mg/kg bw per day, calculated from data on eight polycyclic aromatic hydrocarbons, was considered. The highest dietary exposure to MOAH was also in the young population, with LB–UB mean and 95th percentile estimations of 0.003–0.031 and 0.011–0.059 mg/kg bw per day, respectively. Based on two scenarios on three or more ring MOAH contents in the diet and lacking toxicological information on effects of 1 and 2 ring MOAH, a possible concern for human health was raised
