Abstract
The pharmacokinetics of 6-thioguanine were studied in 10 patients with acute myelogenous leukemia treated with 25-100 mg/m(2) orally. The concentration of 6-thioguanine in plasma was determined with reversed phase high performance liquid chromatography (HPLC). After isolation of leukemic cells and erythrocytes by density centrifugation, HClO4 extraction of nucleotides and isolation of thiol containing substances on mercurial cellulose, the intracellular concentration of phosphorylated 6-thioguanine metabolites was measured by anion exchange HPLC. The plasma peak concentration of 6-thioguanine was significantly correlated (r(2) = 0.60) to the dose administered. In the leukemic cells, the 5'-mono-(TGMP) and 5'-triphosphates (TGTP) of 6-thioguanosine could be detected in nine of the patients. In one patient only TGMP was seen. The diphosphate could be detected in low concentrations in 6 patients. In all patients, the concentration of TGMP was higher than that of TGTP which was higher than the diphosphate. The interindividual variation in cellular TGMP and TGTP concentration was > 100-fold and independent of dose, while the variation in plasma 6-TG was < 15-fold. There was no correlation between dose or plasma area under the concentration versus time curve (AUC) of 6-TG and the cellular AUC of TGMP or TGTP. However, the AUC of TGMP and TGTP correlated significantly (r(2) = 0.64). The t1/2 of the intracellular metabolites and of 6-thioguanine in plasma were in the same order (4.4, 5.2 and 5.0 h for plasma 6-thioguanine, the intracellular mono- and triphosphate respectively). Phosphorylated metabolites of 6-thioguanine were detectable in erythrocytes from 8 patients. The kinetic pattern of the metabolites in erythrocytes was different from that in leukemic cells. While shortly after administration being eliminated according to first order kinetics in the leukemic cells, the concentration of intracellular metabolites in the erythrocytes was raising during the first 24 h after the treatment. The concentration of the metabolites were, however, much (100-fold) lower in erythrocytes compared to leukemic cells. Furthermore, the triphosphate was the predominant metabolite in the erythrocytes and considerable amounts of the diphosphate was seen while the concentration in the monophosphate was low. We conclude that there is a considerable interindividual variation in the cellular pharmacokinetics of TGMP and TGTP. The concentration of the phosphorylated metabolites in the leukemic cells cannot be predicted by determination of plasma 6-thioguanine concentration, nor by the concentration of the same metabolites in the erythrocytes.

Abstract
BACKGROUND Health care focus is shifting for children from surviving childhood cancer to living with it on a daily basis. There is a need to document health and function in the everyday lives of young children with cancer using the multidimensional framework and language of the International Classification of Functioning, Disability and Health--Children and Youth (ICF-CY). AIMS The aims of this study were (1) to document health and functioning in the everyday lives of young children with cancer using ICF-CY codes and (2) to identify a comprehensive code set that can aid clinical assessment. METHOD Interviews with children diagnosed with cancer and their parents, were transcribed, reviewed for content and coded to the ICF-CY using linking procedures. RESULTS A comprehensive code set (n = 70) for childhood cancer was identified. The majority of content identified to codes was related to activity and participation describing social relations with family, peers and professionals, preschool attendance and play, as well as issues related to support and independence. CONCLUSIONS The ICF-CY can be used to document the nature and range of characteristics and consequences of cancer experienced by children. The identified comprehensive code set could be helpful to health care professionals, parents and teachers in assessing and supporting young children's health and everyday life through the cancer trajectory. The comprehensive code set could be developed as a clinical assessment tool for those caring for young children with cancer. The universal language of the ICF-CY means that the utility of a clinical assessment tool based on identified codes can have wide reaching effects for the care of young children with cancer.

Abstract
The membrane transporter P-glycoprotein, encoded by the ABCB1 gene, influences the pharmacokinetics of anti-cancer drugs. We hypothesized that variants of ABCB1 affect outcome and toxicity in childhood acute lymphoblastic leukemia (ALL). We studied 522 Danish children with ALL, 93% of all those eligible. Risk of relapse was increased 2.9-fold for patients with the 1199GA variant versus 1199GG (P=0.001), and reduced 61% and 40%, respectively, for patients with the 3435CT or 3435TT variants versus 3435CC (overall P=0.02). The degree of bone marrow toxicity during doxorubicin, vincristine and prednisolone induction therapy was more prominent in patients with 3435TT variant versus 3435CT/3435CC (P=0.01/P<0.0001). We observed more liver toxicity after high-dose methotrexate in patients with 3435CC variant versus 3435CT/TT (P=0.03). In conclusion, there is a statistically significant association between ABCB1 polymorphisms, efficacy and toxicity in the treatment of ALL, and ABCB1 1199G>A may be a new possible predictive marker for outcome in childhood ALL.

Abstract
The Reno Atmospheric Mercury Intercomparison Experiment (RAMIX) was in Reno, NV from August 22, 2011 to September 16, 2011. The goals of the experiment were to compare existing and new methods for measurements of ambient elemental and oxidized Hg, and to test these with quantitative spikes of Hg(0), HgBr2, O3 and water vapor. In this paper we describe the design, testing, and deployment of a high flow manifold system designed to deliver ambient air and spiked compounds to multiple instruments simultaneously. The manifold was constructed of 1" OD PFA tubing and heated to 115 °C for the entire active zone. Manifold flow was controlled at ∼200 LPM using a blower and a velocity sensor in a feedback control system. Permeation tubes in controlled ovens were used to deliver Hg(0) and HgBr2. Ozone was generated from a small UV lamp in a flow of high purity O2. Water vapor was generated by pumping a flow of purified N2 through heated, high purity water. The spiking delivery for Hg(0), HgBr2, O3, and water vapor after dilution in the manifold ranged up to 20 ng m(-3), 0.64 ng m(-3), 100 ppbv, and 20 g kg(-1), respectively. During laboratory tests the average transmission efficiencies for Hg(0), HgBr2, and O3 were found to be 92%, 76%, and 93%, respectively.

Abstract
AIM The aim of the current study was to examine self-report data on perceptions of unfair treatment due to epilepsy. METHOD We analyzed data from the 2010 Australian Epilepsy Longitudinal Survey, distributed to 621 registrants on the Australian Epilepsy Research Register. A total of 343 responses were received (55% response rate), providing insight into experiences of life with epilepsy in Australia. Responses relating to perceptions of unfair treatment in areas of employment, education and community participation as a result of epilepsy are reported in this article. RESULTS Forty-eight percent of respondents reported perceptions of unfair treatment as a result of their epilepsy, with most providing details of their experiences. Discrimination in the workplace remains of key concern, with 47% citing examples of unfair treatment in this setting. CONCLUSIONS In spite of Australian anti-discrimination laws, findings indicate that full-time employment rates for people with epilepsy are lower than previously reported, with further mechanisms for support required to improve education and reduce experiences of stigma.

Abstract
Abstract This research applied attachment theory to the study of sexual attitudes and behaviors in a sample of late adolescents. Four hundred and seventy heterosexual undergraduate students completed questionnaires assessing attachment (discomfort with closeness; anxiety over relationships). relationship history, communication about sex. sexual self-efficacy and locus of control, and attitudes to condoms. Eight weeks later, participants reported on sexual behaviors occurring during the eight-week interval. and perceived risk of these activities. Both discomfort with closeness and anxiety over relationships were associated with external locus of control for sexual outcomes, and with use of drugs before sexual contact. Anxiety over relationships was linked to unsafe sex and to negative attitudes to condoms, but discomfort with closeness was associated with a more cautious approach to sexual risk-taking. Some results were qualified by gender differences. and by differences between the full sample and those who were sexually active. The findings arc discussed in terms of attachment style and its links with communication and affect regulation. SUMMARY AND CONCLUSIONS This study indicates that attachment dimensions are reliably related to many aspects of sexual attitudes and behaviors among late adolescents. Insecure attachment was linked to increased drug use before sexual contact. Anxiety over relationships was also linked to less safe sexual practice, but discomfort with closeness was associated with a tendency for males to be cautious about sexual risk-taking. The results support the utility of the attachment perspective on adolescent sexuality, but also highlight the complex relations between attachment dimensions and sexual outcomes. Future research would benefit from more detailed investigations of the attitudes, emotions, and cognitions which may mediate the link between attachment style and sexual behavior. For example, those who are highly anxious about their relationships may engage in more risky sexual practices because they fear that non-compliance with partners' wishes will jeopardize their relationship; the tendency to engage in drug use before sexual cpntact may reflect their attempts to boost self-confidence or to manage negative mood states. Research into these issues has the potential to explain how attachment insecurity is played out in patterns of sexual activity.

Abstract
BACKGROUND Allergic disease has been associated with altered intestinal microbiota. Therefore, probiotics have been suggested as a potential treatment for eczema. OBJECTIVE We investigated whether dietary supplementation of infants with eczema at age 3-6 months with Lactobacillus paracasei CNCM I-2116 or Bifidobacterium lactis CNCM I-3446 had a treatment effect or altered allergic disease progression. METHODS Primary outcome included eczema severity (SCORing Atopic Dermatitis, SCORAD) 3 months post-randomization. Secondary: SCORAD (other visits); infant dermatitis quality of life (IDQoL); gastrointestinal permeability; urinary eosinophilic protein X; allergen-sensitization; allergic symptoms (age 12, 18, 36 months). A total of 208 infants aged 3-6 months with physician-diagnosed eczema were recruited; 137/208 (SCORAD ≥ 10, consuming ≥ 200 mL standard formula/day) were randomized to daily supplements containing L. paracasei or B. lactis or placebo for a 3-month period, while receiving extensively hydrolysed whey-formula (dairy-free diet). There were two open observational groups, one group exclusively breastfed (n = 22) and the other, standard formula-fed (n = 49). TRIAL NUMBER ISRCTN41490500. RESULTS Eczema severity decreased significantly over time in all groups. No significant difference was observed between randomized groups after 12-week treatment-period (SCORAD-score pre-/post-intervention: B. lactis 25.9 [95% CI: 22.8-29.2] to 12.8 [9.4-16.6]; L. paracasei 25.4 [22.1-29] to 12.5 [9.2-16.4]; placebo 26.9 [23.4-30.6] to 11.8 [9.6-14.3]; P = 0.7). Results were similar when analysis was controlled for allergen-sensitization, or when only sensitized infants were analysed. No differences were found for secondary outcomes. No difference was observed in SCORAD-score between randomized and observational groups. CONCLUSION AND CLINICAL RELEVANCE We found no benefit from supplementation with B. lactis or L. paracasei in the treatment of eczema, when given as an adjunct to basic topical treatment, and no effect on the progression of allergic disease from age 1 to 3 years.
