Developing a population approach to gambling health issues

The Institute of Public Health in Ireland (IPH) has developed this briefing paper to highlight the health impacts connected to gambling and in particular problem gambling.  This paper was developed to give information to Government Departments who are currently reviewing gambling legislation across the island of Ireland.  It draws attention to the impact problem gambling can have on the individual, family and community health and well-being.

Liver kidney microsomes type 1 antibodies are associated with 80% reduction of the CYP2D6 activity in patients with chronic hepatitis C

Introduction Liver kidney microsomal type 1 (LKM-1) antibodies have been shown to decrease CYP2D6 activity in vitro. We investigated whether LKM-1 antibodies might reduce CYP2D6 activity also in vivo.Materials and Methods All patients with chronic hepatitis C and LKM-1 antibodies enrolled in the Swiss Hepatitis C Cohort Study (SCCS) were assessed: ten were eligible and fi tted to patients without LKM-1 antibodies. Patients were genotyped for CYP2D6 variants to exclude individuals with a poor metabolizer genotype. CYP2D6 activity was measured by a specifi c substrate using the dextromethorphan/dextrorphan (DEM/DOR) metabolic ratio to classify patients into four activity phenotypes (i.e. ultrarapid, extensive, intermediate and poor metabolizers). The concordance between phenotype based on DEM/DOR ratio and phenotype expected from genotype was examined in LKM-1 positive and negative patients. Groups were compared with respect to the DEM/DOR metabolic ratio.Results All patients had a CYP2D6 extensive metabolizer genotype. The observed phenotype was concordant with CYP2D6 genotype in most LKM-negative patients, whereas only three (30%) LKM-1 positive patients had a concordant phenotype (six presented an intermediate and one a poor metabolizer phenotype). The median DEM/DOR ratio was six-fold higher in LKM-1 positive than in LKM-1 negative patients (0.096 vs. 0.016, p = 0.004), indicating that CYP2D6 metabolic function was significantly reduced in the presence of LKM-1 antibodies.Conclusion In chronic hepatitis C patients with LKM-1 antibodies, the CYP2D6 metabolic activity was on average reduced by 80%. The impact of LKM-1 antibodies on CYP2D6-mediated drug metabolism pathways warrants further translational studies in the setting of new protease inhibitor therapies

Higher memory responses in HIV-infected and kidney transplanted patients than in healthy subjects following priming with the pandemic vaccine.

BACKGROUND: Memory responses require immune competence. We assessed the influence of priming with AS03-adjuvanted pandemic vaccine (Pandemrix®) on memory responses of HIV patients, kidney recipients (SOT) and healthy controls (HC). METHOD: Participants (HIV: 197, SOT: 53; HC: 156) were enrolled in a prospective study and 390/406 (96%) completed it. All had been primed in 2009/2010 with 1 (HC) or 2 (patients) doses of Pandemrix®, and were boosted with the 2010/2011 seasonal influenza vaccine. Geometric mean titres and seroprotection rates were measured 12 months after priming and 4 weeks after boosting. Primary and memory responses were directly compared in 191 participants (HCW: 69, HIV: 71, SOT: 51) followed during 2 consecutive seasons. RESULTS: Most participants (HC: 77.8%, HIV: 77.6%, SOT: 66%) remained seroprotected at 12 months post-priming. Persisting A/09/H1N1 titers were high in HIV (100.2) and HC (120.1), but lower in SOT (61.4) patients. Memory responses reached higher titers in HIV (507.8) than in HC (253.5) and SOT (136.9) patients. Increasing age and lack of HAART reduced persisting and memory responses, mainly influenced by residual antibody titers. Comparing 2009/2010 and 2010/2011 titers in 191 participants followed for 2 seasons indicated lower post-2010/2011 titers in HC (240.2 vs 313.9), but higher titers in HIV (435.7 vs 338.0) and SOT (136 vs 90.3) patients. CONCLUSIONS: Priming with 2 doses of Pandemrix® elicited persistent antibody responses and even stronger memory responses to non-adjuvanted seasonal vaccine in HIV patients than 1 dose in healthy subjects. Adjuvanted influenza vaccines may improve memory responses of immunocompromised patients. TRIAL REGISTRATION: ClinicalTrials.gov NCT01022905.

Developing a Workplace Policy on Domestic Violence and Abuse (PDF 219KB)

This guide for employers has been produced by the Regional Steering Group on Domestic Violence in line with the strategy and action plan “Tackling Violence at Home” published in October 2005. The Regional Steering Group is a group of about 30 members representing the statutory and voluntary agencies involved in dealing with domestic violence. The guidance provides advice on how employers can develop increased awareness and more effective responses to domestic violence in the workplace for the benefit of all staff. The Regional Steering Group acknowledges that some employers already have good workplace policies in place and it encourages all employers across the public, private, voluntary and community sectors to use the guidance to develop a workplace policy on domestic violence. åÊ

Purification and characterization of (Na+ + K+)-ATPase from toad kidney

This report describes the partial purification and the characteristics of (Na+ + K+)-ATPase (ATP phosphohydrolase, EC 3.6.1.3) from an amphibian source. Toad kidney microsomes were solubilized with sodium deoxycholate and further purified by sodium dodecyl sulphate treatment and sucrose gradient centrifugation, according to the methods described by Lane et al. [(1973) J. Biol. Chem. 248, 7197--7200], Jørgensen [(1974) Biochim. Biophys. Acta 356, 36--52] and Hayashi et al. [(1977) Biochim. Biophys. Acta 482, 185--196]. (Na+ + K+)-ATPase preparations with specific activities up to 1000 mumol Pi/mg protein per h were obtained. Mg2+-ATPase only accounted for about 2% of the total ATPase activity. Sodium dodecyl sulphate-polyacrylamide gel electrophoresis revealed three major protein bands with molecular weights of 116 000, 62 000 and 26 000. The 116 000 dalton protein was phosphorylated by [gamma-32P]ATP in the presence of sodium but not in the presence of potassium. The 62 000 dalton component stained for glycoproteins. The Km for ATP was 0.40 mM, for Na+ 12.29 mM and for K+ 1.14 mM. The Ki for ouabain was 35 micron. Temperature activation curves showed two activity peaks at 37 degrees C and at 50 degrees C. The break in the Arrhenius plot of activity versus temperature appeared at 15 degrees C.
