PROTOCOL: An evidence and gap map of studies of implementation issues for interventions for those affected by and at risk of homelessness in high-income countries.

This is the protocol for a Campbell systematic review. The objectives are as follows. The proposed evidence and gap map will present relevant process evaluations and other studies of barriers and facilitators, both qualitative and quantitative, for eligible homelessness interventions to highlight the issues arising in the implementation of these interventions. Specifically, the objectives of the map are to: (i) develop a clear taxonomy of interventions and implementation issues (e.g., barriers and facilitators-factors which works as barriers to hinder successful implementation of policies and programmes and factors which facilitate the intervention and therefore support its implementation) related to homelessness in high-income countries; (ii) map available systematic reviews and primary studies of the implementation issues of interventions for those experiencing homelessness and those at risk of homelessness, with an overview provided in a summary report; (iii) provide a searchable database of included studies accessible to research users via CHI website.

Long-term follow-up of women with gestational diabetes mellitus: the South Australian Gestational Diabetes Mellitus Recall Register.

BACKGROUND: Women who have had gestational diabetes mellitus (GDM) are at increased risk of developing type 2 diabetes. Early detection and management of type 2 diabetes are important for reducing associated complications and costs. AIMS: To evaluate an existing register for long-term follow-up of women who have been diagnosed with GDM. METHODS: Recruitment to the GDM Recall Register began at the diabetes centres of two hospitals in South Australia from July 2002, and was expanded to include a third hospital from September 2005. Women enrolled on the Register are sent an annual letter reminding them that they are at increased risk of developing type 2 diabetes and encouraging them to get their blood glucose checked. An update form is also included for women to complete and return to the Register. RESULTS: As at 30 June 2009, 817 women were enrolled on the Register. Of women diagnosed with GDM at the participating hospital sites, recruitment to the Register was 68.4% in 2002 and 64.4% in 2007. Of the 429 women who had been sent their first reminder letter, 46.4% had returned the update form. Of these, 56.3% had undergone a glucose test for diabetes. Two women reported developing type 2 diabetes. CONCLUSIONS: Expansion of the GDM Recall Register is likely to result in increased opportunities for early detection of diabetes for this high-risk group in South Australia, therefore allowing earlier intervention and treatment to prevent or reduce serious, costly diabetes-related complications.

Polyacidic multiloading metal extractants.

Novel polynucleating, di- and tri-acidic ligands have been designed to increase the molar and mass transport efficiencies for the recovery of base metals by solvent extraction.

Modelling student age-groups in the subnational population projections for England: an investigation into potential improvements.

This article describes research aimed at improving modeling of student age-groups in the ONS subnational population projections for England. A number of data-sources were investigated, and the research focused on Higher Education Statistics Agency data. Although the coverage of HESA data is not sufficient to enable student populations to be projected separately, the data have been used to devise an adjustment method for the student-age population. Both the data and method will be monitored and, if appropriate, used in future projections.
