RESUMO
BACKGROUND: Antisocial personality disorder (ASPD), although associated with very significant health and social burden, is an under-researched mental disorder for which clinically effective and cost-effective treatment methods are urgently needed. No intervention has been established for prevention or as the treatment of choice for this disorder. Mentalization-based treatment (MBT) is a psychotherapeutic treatment that has shown some promising preliminary results for reducing personality disorder symptomatology by specifically targeting the ability to recognize and understand the mental states of oneself and others, an ability that is compromised in people with ASPD. This paper describes the protocol of a multi-site RCT designed to test the effectiveness and cost-effectiveness of MBT for reducing aggression and alleviating the wider symptoms of ASPD in male offenders subject to probation supervision who fulfil diagnostic criteria for ASPD. METHODS: Three hundred and two participants recruited from a pool of offenders subject to statutory supervision by the National Probation Service at 13 sites across the UK will be randomized on a 1:1 basis to 12 months of probation plus MBT or standard probation as usual, with follow-up to 24 months post-randomization. The primary outcome is frequency of aggressive antisocial behaviour as assessed by the Overt Aggression Scale - Modified. Secondary outcomes include violence, offending rates, alcohol use, drug use, mental health status, quality of life, and total service use costs. Data will be gathered from police and criminal justice databases, NHS record linkage, and interviews and self-report measures administered to participants. Primary analysis will be on an intent-to-treat basis; per-protocol analysis will be undertaken as secondary analysis. The primary outcome will be analysed using hierarchical mixed-effects linear regression. Secondary outcomes will be analysed using mixed-effects linear regression, mixed-effects logistic regression, and mixed-effects Poisson models for secondary outcomes depending on whether the outcome is continuous, binary, or count data. A cost-effectiveness and cost-utility analysis will be undertaken. DISCUSSION: This definitive, national, multi-site trial is of sufficient size to evaluate MBT to inform policymakers, service commissioners, clinicians, and service users about its potential to treat offenders with ASPD and the likely impact on the population at risk. TRIAL REGISTRATION: ISRCTN 32309003 . Registered on 8 April 2016.

AIM: To investigate the knowledge and practice of midwives providing lead maternity care (LMC) in Otago, regarding gestational weight gain (GWG). METHODS: A qualitative study was conducted using three semi-structured focus groups and one in-depth interview. A total of 12 midwives, including one student midwife, were interviewed. Transcripts were analysed using generic coding and thematic analysis. At the conclusion of the focus groups no new themes were emerging. RESULTS: Themes discussed included midwives' knowledge of GWG, methods used to identify BMI and weight gain throughout pregnancy, current management, barriers to management and tools used to overcome these barriers. There was satisfactory knowledge of the risks associated with excess GWG, however, adherence to current New Zealand guidelines and awareness of international guidelines in this area was limited. Management of GWG was highly varied and the weighing of pregnant women was not common practice. Sensitivity around the topic of weight management was identified as a major barrier to care. CONCLUSIONS: The management inconsistencies highlighted in this study have identified a need for New Zealand guidelines for the management of GWG. Clear guidelines along with increased education and collaboration between health professionals would help alleviate the current uncertainty regarding weight management in pregnancy.

OBJECTIVE: To describe changes in the iodine status of Tasmanians following voluntary fortification of bread with iodine in October 2001. DESIGN AND SETTING: Post-intervention, cross-sectional urinary iodine surveys of Tasmanian schoolchildren aged 8-11 years were used to assess population iodine status. Participants were selected using a one-stage cluster sampling method. The sampling frame comprised classes containing fourth-grade children from all Tasmanian government, Catholic and independent schools. Results were compared with pre-intervention survey results. MAIN OUTCOME MEASURES: Median urinary iodine concentration (UIC) and percentage of UIC < 50 microg/L ascertained from spot urine samples. RESULTS: Median UIC was 75 microg/L in 1998, 72 microg/L in 2000, 105 microg/L in 2003, 109 microg/L in 2004 and 105 microg/L in 2005. Median UIC in post-intervention years (2003-2005) was significantly higher than in pre-intervention years. The percentage of UIC results < 50 microg/L was 16.9% in 1998, 18.7% in 2000, 10.1% in 2003, 10.0% in 2004 and 10.5% in 2005. CONCLUSION: Despite methodological differences between the pre- and post-intervention surveys, switching to iodised salt in bread appears to have resulted in a significant improvement in iodine status in Tasmania. Given iodine deficiency has been identified in other parts of Australia and in New Zealand, mandatory iodine fortification of the food supply in both countries is worthy of consideration. As voluntary fortification relies on industry goodwill, mandating fortification could be expected to enhance population reach and give a greater guarantee of sustainability in Tasmania.

In eukaryotes, many essential secreted proteins and peptide hormones are excised from larger precursors by members of a class of calcium-dependent endoproteinases, the prohormone-proprotein convertases (PCs). Furin, the best-characterized member of the mammalian PC family, has essential functions in embryogenesis and homeostasis but is also implicated in various pathologies such as tumor metastasis, neurodegeneration and various bacterial and viral diseases caused by such pathogens as anthrax and pathogenic Ebola virus strains. Furin cleaves protein precursors with narrow specificity following basic Arg-Xaa-Lys/Arg-Arg-like motifs. The 2.6 A crystal structure of the decanoyl-Arg-Val-Lys-Arg-chloromethylketone (dec-RVKR-cmk)-inhibited mouse furin ectodomain, the first PC structure, reveals an eight-stranded jelly-roll P domain associated with the catalytic domain. Contoured surface loops shape the active site by cleft, thus explaining furin's stringent requirement for arginine at P1 and P4, and lysine at P2 sites by highly charge-complementary pockets. The structure also explains furin's preference for basic residues at P3, P5 and P6 sites. This structure will aid in the rational design of antiviral and antibacterial drugs.
