    Demographics, including proportion of male patients, did not differ significantly between patients with and without “iatrogenic” TS, but plasma concentrations of the catecholamine metabolite normetanephrine tended to be greater (median 1149 pmol/L vs 938 pmol/L; p = 0.03). Long-term survival (median follow-up 3 years) was marginally (p = 0.13) worse for patients with “iatrogenic” TS. CONCLUSION Potentially iatrogenic precipitation of TS attacks (via iatrogenic elevation of catecholamine levels and β2-adrenoceptor stimulation) is common, associated with greater elevation of plasma normetanephrine concentrations, and also with a trend towards increased long-term mortality when compared to the remainder of TS patients.The purpose of this study was to examine the factor structure of vocabulary. We believe that not only is vocabulary multidimensional, but depth of vocabulary knowledge should also be assessed with multiple measures since it too, is composed of multiple aspects. Furthermore, to explore the predictive validity of the different aspects of vocabulary knowledge, we assessed the relationship between vocabulary breadth, vocabulary depth, and reading comprehension in adults with low literacy skills. The participants were 103 adults. They completed 12 tasks that have been used in past studies to measure vocabulary breadth, depth, and reading comprehension. We had several important findings. First, we confirmed that all of the assessments were highly reliable for adults with low literacy skills. Second, the results of the factor analysis indicated two distinct vocabulary factors. Finally, both breadth and depth contribute independently to explaining variance in reading comprehension. Implications for vocabulary measurement are suggested.The views of family carers who provide end of life care to people of advanced age are not commonly known. We conducted a bicultural study with bereaved New Zealand Māori (indigenous) and non-indigenous family carers who, on behalf of their older family member, reflected on the end of life circumstances and formal and informal care experienced by the older person. Semi-structured interviews were undertaken with 58 people (19 Māori and 39 non-Māori), who cared for 52 family members who died aged over 80 years. A Kaupapa Māori thematic analysis of family/whānau perspectives identified examples of good holistic care as well as barriers to good care. These are presented in a proposed Whare Tapa Whā Older Person’s Palliative Care model. Good health care was regarded by participants as that which was profoundly relationship-oriented and upheld the older person’s mana (authority, status, spiritual power) across four critical health domains Whānau (social/family), Hinengaro (emotional/mental), Wairua (spiritual) and Tinana (physical) health domains. However, poor health care on one level impacted on all four domains affecting (reducing) mana (status). The “indigenous” model was applicable to both indigenous and non-indigenous experiences of end of life care for those in advanced age. Thus, Indigenous perspectives could potentially guide and inform end of life care for all.Lead (Pb) in soils can be transferred to plants, animals, and even humans. The toxicity of Pb is worrisome and therefore environmental quality criteria, established by laws to support the management of contaminated sites, have been developed to prevent its deleterious effects in a wide range of soils, uses, and occupations. In Brazil, the CONAMA Resolution 420/2009 established that Brazilian states may define their prevention values (PV) for metals in soils. However, the established values should be well studied, since a wide variation of sensitivity of species exposed to Pb is reported and several have a high tolerance. click here We aimed to evaluate Pb toxicity to validate the suitability of the current Brazilian Pb-prevention value. A trial was carried with two plant species (sorghum and soybean) grown in two tropical soils (Typic Hapludox and Rhodic Acrudox), following ISO 11.269-2 protocols (ISO 2012). The tested soils were contaminated with Pb-acetate at the following concentrations 0, 200, 400, 800, 1200, 1600, 2200, 2800, and 3200 mg kg-1 of dry soil. Differences regarding species sensitivity were observed and sorghum seemed to be less sensitive to Pb concentration in soils. Soil characteristics as higher clay and organic matter content were responsible for decreasing the overall availability of Pb for plants. Using data from this study and from the literature, we constructed a species sensitivity distribution curve and calculated the HC5 (hazardous concentration to 5% of variables evaluated). The HC5 was 132.5 mg kg-1, which suggests that the PV currently used in Brazil (72 mg kg-1) is sufficiently protective for Brazilian soils.OBJECTIVES To determine long-term predictors of health-related quality of life (HRQOL) and evaluate the treatment effect of highly active antiretroviral therapy (HAART) on HRQOL in the US Military HIV Natural History Study (NHS) cohort. METHODS Participants were a nested cohort of the NHS who responded to the Rand Short Form 36 questionnaire administered from 2006 to 2010. Physical component summary scores (PCS) and mental component summary scores (MCS) were computed using standard algorithms. HAART-status was categorized as non-protease inhibitor-based (NPI-HAART), protease inhibitor-based (PI-HAART), HAART-naïve, or off-HAART. Mixed linear random effects models were used to estimate changes in PCS and MCS over time for treatment and covariates (including CD4 count, HIV viral load, medical and mental comorbidities). RESULTS Eight hundred and twelve participants met the inclusion criteria. There was no difference in PCS or MCS between those on PI-HAART compared to NPI-HAART. Significant predictors of PCS were CD4 count  less then  200 cells/mm3 (β = - 2.90), CD4 count 200-499 cells/mm3 (β = - 0.80), and mental comorbidity (β = - 3.23). Others were medical comorbidity, AIDS-defining illness, being on NPI-HAART, HAART-naïve, age, and rank. Those with medical comorbidities experienced yearly improvement in PCS. Predictors of MCS were CD4 count  less then  200 cells/mm3 (β = - 2.53), mental comorbidity (β = - 4.58), and being African American (β = 2.59). CONCLUSION HRQOL was significantly affected by low CD4 count, medical and mental comorbidities. Addressing these modifiable factors would be expected to improve the physical and mental HRQOL of the cohort. Our study did not find any treatment benefit of NPI-HAART over PI-HAART on HRQOL in the long term.
