Report for the scientific sojourn at the Imperial College of London, United Kingdom, from 2007 to 2009. PTEN is a tumour suppressor enzyme that plays important roles in the PI3K pathway which regulates growth, proliferation and survival and is thus related to many human disorders such as diabetes, neurodegenerative diseases, cardiovascular complications and cancer. It is hence of great interest to understand in detail its molecular behaviour and to find small molecules that can switch on/off its activity. For this purpose, metal complexes have been synthesized and preliminary studies in vivo show that all are capable of inhibiting PTEN.

BACKGROUND: Neuroimaging studies show cerebellar activations in a wide range of cognitive tasks and patients with cerebellar lesions often present cognitive deficits suggesting a cerebellar role in higher-order cognition. OBJECTIVE: We used cathodal transcranial direct current stimulation (tDCS), known to inhibit neuronal excitability, over the cerebellum to investigate if cathodal tDCS impairs verbal working memory, an important higher-order cognitive faculty. METHOD: We tested verbal working memory as measured by forward and backward digit spans in 40 healthy young participants before and after applying cathodal tDCS (2 mA, stimulation duration 25 min) to the right cerebellum using a randomized, sham-controlled, double-blind, cross-over design. In addition, we tested the effect of cerebellar tDCS on word reading, finger tapping and a visually cued sensorimotor task. RESULTS: In line with lower digit spans in patients with cerebellar lesions, cerebellar tDCS reduced forward digit spans and blocked the practice dependent increase in backward digit spans. No effects of tDCS on word reading, finger tapping or the visually cued sensorimotor task were found. CONCLUSION: Our results support the view that the cerebellum contributes to verbal working memory as measured by forward and backward digit spans. Moreover, the induction of reversible "virtual cerebellar lesions" in healthy individuals by means of tDCS may improve our understanding of the mechanistic basis of verbal working memory deficits in patients with cerebellar lesions.

El sistema nerviós central (SNC) i el sistema immunitari (SI) estan estretament connectats. Es produeixen nombroses alteracions en el sistema immunitari després de la isquèmia i la inflamació es reconeix com una de les principals causes de la progressió de la lesió isquèmica. És molt important determinar el paper de les diferents cèl•lules implicades en la resposta immunitària i inflamatòria després de la isquèmia i el perfil de citocines que s’alliberen. A partir de l’estudi de les diferents poblacions de leucòcits en sang circulant després de la isquèmia, hem determinat que la subpoblació de monòcits (CD43high/CD11bhigh) augmenta a 48h de manera proporcional al volum d’infart. Aquesta població està formada per dos subtipus descrits de monòcits, els no clàssics (CD43high/Ly6C-) i els intermedis (CD43high/Ly6Cdim), i sembla expressar un perfil de citocines anti-inflamatòries així com una major capacitat fagocítica. Per altra banda, observem la presència de CD43 en el cervell i la seva degradació a 4 dies després de la isquèmia. També s’observa l’aparició de la fracció soluble del CD43 en el parènquima cerebral després del trencament de la barrera hematoencefàlica. Addicionalment, hem estudiat com s’alteren els canvis a nivell immunològic en ratolins deficients en CD69 i hem observat una pitjor progressió del volum d’infart en els animals CD69KO. A més a més hem volgut esbrinar el paper dels limfòcits utilitzant ratolins RAG (-/-) que tenen infarts més petits que els WT, però quan aquests careixen de CD69, tenen infarts significativament més grans. En l’estudi del procés inflamatori en la isquèmica, hem treballat amb ratolins deficient en ApoE i IL10. Pel que fa als ratolins ApoE (-/-), observem que tenen un volum d’infart més gran a les 24h i que es manté fins als 4 dies, i proposem que NFkB pot tenir un paper molt rellevant en aquest procés. Pel que fa a la IL-10, els animals deficients en aquesta citocina presenten un volum d’infart major i una expressió de citocines proinflamatòries més alt. A més a més, els ratolins IL10 KO presenten uns nivells de IL-12 més elevats de manera basal, i proposem que això és degut a la falta de la IL-10 per a inhibir la via.

The introduction of a maximum 48 hour working week for Non Consultant Hospital Doctors by 2010 will have significant implications for both Doctors in training and service delivery in our hospitals. This report focuses on how this reduction in working hours can be achieved and the many directly related issues that need to be addressed Download the Report here

The Working Group on Elder Abuse is pleased to present this Report. It provides a foundation for the development of policy and procedures to respond to actual or alleged cases of elder abuse.  Aim of policy and proceduresThe aim of the policy and procedures presented here is to create a context in which older people and those concerned about the abuse of older people can disclose their concerns and receive an appropriate response. The basis of the policy (and the procedures flowing from it) is the recognition of the right of older people to live independent lives with dignity. Download document here

Second Report of the Working Group on Child and Adolescent Psychiatric Services The Minister for Health and Children established a Working Group on Child and Adolescent Psychiatry in June 2000 with the following terms of reference:·  To examine the current state of child and adolescent psychiatric services in the country; ·  To carry out a needs analysis of the population aged 0-18 years for such services and to identify shortcomings in meeting such needs; ·  To make recommendations on how child and adolescent psychiatric services should be developed in the short, medium and long term to meet identified needs.

Meningococcal disease is a serious condition with high morbidity and significant mortality. The Department of Health and Children’s Working Group on Bacterial Meningitis and Related Conditions has monitored the epidemiology of Meningococcal disease and in 1997, in its first report, proposed strategies to prevent this infection and its complications. This report has been reviewed and updated and a second report issued in July 1999. This Report describes the epidemiology of Meningococcal disease and includes practical guidance in relation to the management of clusters and chemoprophylaxis. The Report also includes guidelines in relation to the hospital based management of suspected Meningococcal Sepsis/Meningitis and which can be adapted depending on local circumstances Download the Report here
