Molecular neuro-oncology in clinical practice: a new horizon.

Primary brain tumours are heterogeneous in histology, genetics, and outcome. Although WHO's classification of tumours of the CNS has greatly helped to standardise diagnostic criteria worldwide, it does not consider the substantial progress that has been made in the molecular classification of many brain tumours. Recent practice-changing clinical trials have defined a role for routine assessment of MGMT promoter methylation in glioblastomas in elderly people, and 1p and 19q codeletions in anaplastic oligodendroglial tumours. Moreover, large-scale molecular profiling approaches have identified new mutations in gliomas, affecting IDH1, IDH2, H3F3, ATRX, and CIC, which has allowed subclassification of gliomas into distinct molecular subgroups with characteristic features of age, localisation, and outcome. However, these molecular approaches cannot yet predict patients' benefit from therapeutic interventions. Similarly, transcriptome-based classification of medulloblastoma has delineated four variants that might now be candidate diseases in which to explore novel targeted agents.

Direct Payments Policy and Practice Review Report (PDF 243 KB)

Direct Payments are cash payments made in lieu of social service provisions, to individuals who have been assessed as needing services. Direct Payments increase choice and promote independence. They provide for a more flexible response than may otherwise be possible for the service user and carer. They allow individuals to decide when and in what form services are provided and who provides them, who comes into their home and who becomes involved in very personal aspects of their lives. Direct Payments put real power into the hands of service users and carers, and allow them to take control over their lives. Access to Direct Payments as a means of delivering social services in Northern Ireland has been available since 1996 under the Personal Social Services (Direct Payments) (Northern Ireland) Order 1996. Since then take up of Direct Payments has been limited in number with the majority being accessed in the physical disability programme. åÊ

Plasmacytoid dendritic cells in melanoma: can we revert bad into good?

Tumor-infiltrating plasmacytoid dendritic cells (pDCs) promote an immunosuppressive milieu that drives tumor growth in melanoma. This phenomenon typically results from the lack of appropriate pDC activation signals in the tumor microenvironment, but it is also actively controlled by tumor cells, which have evolved strategies to inhibit type I IFN production by pDCs. In this issue, Camisaschi et al. identify a new mechanism in which tumors avoid type I IFN production by triggering LAG-3-dependent activation of pDCs. Combination therapies that restore pDC functionality and trigger innate activation to produce type I IFN should be envisaged to induce effective antitumor immunity.

Test methods: anabolics.

In the International Olympic Committee (IOC) accredited laboratories, specific methods have been developed to detect anabolic steroids in athletes' urine. The technique of choice to achieve this is gas-chromatography coupled with mass spectrometry (GC-MS). In order to improve the efficiency of anti-doping programmes, the laboratories have defined new analytical strategies. The final sensitivity of the analytical procedure can be improved by choosing new technologies for use in detection, such as tandem mass spectrometry (MS-MS) or high resolution mass spectrometry (HRMS). A better sample preparation using immuno-affinity chromatography (IAC) is also a good tool for improving sensitivity. These techniques are suitable for the detection of synthetic anabolic steroids whose structure is not found naturally in the human body. The more and more evident use, on a large scale, of substances chemically similar to the endogenous steroids obliges both the laboratory and the sports authorities to use the steroid profile of the athlete in comparison with reference ranges from a population or with intraindividual reference values.

Suboptimal Management of Coronary Risk in Daily Clinical Practice: Results from a Mediterranean Cohort of HIV-Infected Patients With Myocardial Infarction

Background: The incidence of cardiovascular events in HIV patients has fallen. Methods: We identified 81 patients with a history of coronary events from 2 hospitals in Spain to evaluate management of CVRF before and after the event. Results: The prevalence of coronary events was 2.15%. At the time of the coronary event, CVRF were highly prevalent. Decrease in total cholesterol (P=0.025) and LDLc(P=0.004) was observed. LDLc and HDLc were determined and the percentage of patients with LDLc &100 mg/dL remained stable at the last visit. Conclusions: The prevalence of coronary disease in our cohort was low. Although CVRF were highly.
