Resistant forms of childhood acute lymphoblastic leukaemia (ALL) constitute a leading cause of cancer-related deaths in children. Despite tremendous improvements in therapy, 25-30% of patients still experience a relapse and many of them occur in patients stratified as low risk. Further treatment is often toxic, frequently unsuccessful and carries the risk of significant long-term morbidity. For the design of more appropriate therapy, information on the biology of relapsed ALL is urgently require ....Resistant forms of childhood acute lymphoblastic leukaemia (ALL) constitute a leading cause of cancer-related deaths in children. Despite tremendous improvements in therapy, 25-30% of patients still experience a relapse and many of them occur in patients stratified as low risk. Further treatment is often toxic, frequently unsuccessful and carries the risk of significant long-term morbidity. For the design of more appropriate therapy, information on the biology of relapsed ALL is urgently required. The sequencing of the human genome and advanced screening technology (microarrays) allow the detailed analysis of expression patterns in large numbers of specimens. We propose to study the genetic features of this disease by investigating 28 childhood ALL patients from whom we have stored specimens received at two time points, one at diagnosis and one at relapse. The hypothesis of this study is that relapsed leukaemias display genetic features which are correlated to their resistance to therapy. The specific questions we will be asking are: (1) Which genes are expressed at high levels in leukaemia specimens at the time of relapse while not expressed (or expressed at lower levels) at the time of diagnosis and vice versa? (2) What is the function of differentially expressed genes? (3) Is the pattern of gene expression correlated with resistance to the particular drug therapy used? (4) Is the leukaemia clone at relapse related or unrelated to the clone present at diagnosis, as determined by receptor rearrangement? The expression levels of identified discriminator genes will be confirmed by real-time quantitative polymerase chain reaction (PCR). The quality of this set of specimens makes them particularly suited to achieve the stated goals, providing a unique opportunity to investigate drug resistance in childhood ALL. The data generated will provide the basis for the examination of genes suitable as new therapeutic targets.Read moreRead less
Improving The Control Of Hypertension In Rural India: Overcoming The Barriers To Diagnosis And Effective Treatment

Summary
We know little about barriers to the control of high blood pressure in rural regions of low income countries. These rural areas differ in the proportion of people with high blood pressure, the risk factors for high blood pressure and most likely the barriers to good treatment of blood pressure. We aim to find out what these barriers are, and develop and test a program that can be used to improve control of high blood pressure in very diverse settings.
Health Care Priorities: The Community's Preferences For Using Community Preferences

Summary
Determining how health care resources should be allocated - often termed rationing or priority setting - has traditionally been carried out by health care personnel, usually doctors but increasingly managers. More recently there has been a move to involve the general public in this process. Much of the research in this area has focussed on the methods used to elicit community preferences.

More recently there has been a move to involve the general public in this process. Much of the research in this area has focussed on the methods used to elicit community preferences. While this is an important area of investigation, a prior issue of how community members feel about the use of their preferences in informing health care priorities needs to be investigated. Four specific questions will be addressed in this study: (i) do members of the general public feel that, as individuals, they have a legitimate role to play in informing priority decisions in health care? if so why? if not, why not? (ii) does the nature-level-setting of the decisions for which priorities are to be set affect whether individual members of the public would wish to participate in the priority setting process? (e.g. different health services, medical procedures-treatments, diseases) (iii) whose preferences should be used if not the community's? (iv) faced ex post with the preferences of the community and the preferences (possibly different) of health service decision makers (i.e. Oexperts'), does this knowledge affect preferences for having community preferences count? A number of health authorities are currently looking for ways of engaging local communities in health care decision making. This study will indicate the appropriate levels at which community preferences are to be elicited and the type of decisions and settings in which they are most relevant.Read moreRead less
