    ALSPAC,The Avon Longitudinal Study of Parents and Children

    PAEDIATRIC & PERINATAL EPIDEMIOLOGY, Issue 1 2001
    Golding
    ALSPAC (The Avon Longitudinal Study of Parents and Children, formerly the Avon Longitudinal Study of Pregnancy and Childhood) was specifically designed to determine ways in which the individual's genotype combines with environmental pressures to influence health and development. To date, there are comprehensive data on approximately 10 000 children and their parents, from early pregnancy until the children are aged between 8 and 9. The study aims to continue to collect detailed data on the children as they go through puberty noting, in particular, changes in anthropometry, attitudes and behaviour, fitness and other cardiovascular risk factors, bone mineralisation, allergic symptoms and mental health. The study started early during pregnancy and collected very detailed data from the mother and her partner before the child was born. This not only provided accurate data on concurrent features, especially medication, symptoms, diet and lifestyle, attitudes and behaviour, social and environmental features, but was unbiased by parental knowledge of any problems that the child might develop. From the time of the child's birth many different aspects of the child's environment have been monitored and a wide range of phenotypic data collected. By virtue of being based in one geographic area, linkage to medical and educational records is relatively simple, and hands-on assessments of children and parents using local facilities has the advantage of high quality control. The comprehensiveness of the ALSPAC approach with a total population sample unselected by disease status, and the availability of parental genotypes, provides an adequate sample for statistical analysis and for avoiding spurious results. The study has an open policy in regard to collaboration within strict confidentiality rules. [source]


    Practitioner Review: Clinical applications of pediatric hypnosis

    THE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 8 2007
    Jeffrey I. Gold
    Background:, Over the past quarter century, hypnosis has been employed in a broad range of pediatric clinical settings; however, its efficacy and feasibility as a treatment approach for children and adolescents remain in question. Method:, Published studies on the role of clinical hypnosis in the management of specific pediatric medical and psychological conditions were identified and reviewed. Results:, Pediatric clinical hypnosis has been employed in diverse medical settings to treat primary conditions (e.g., enuresis), as well as to address factors related to management of the condition (e.g., skills training for asthma) or its treatment (e.g., burn dressing changes). Despite great breadth to the possible applications of pediatric hypnosis and many reported successes, much of the present research comprises case histories and small, uncontrolled group studies. Conclusion:, To date, research in pediatrics views clinical hypnosis as a promising tool with the potential to help manage a variety of conditions. However, additional research, particularly utilizing randomized, controlled methodologies and adequate sample sizes, is required. [source]


    Psychosocial interventions for non-professional carers of people with Parkinson's disease: a systematic scoping review

    Abstract Title.,Psychosocial interventions for non-professional carers of people with Parkinson's disease: a systematic scoping review. Aim., This paper is a report of a scoping review to systematically identify and collate the evidence on psychosocial interventions for non-professional carers of people with Parkinson's disease. Background., Carers are critical to people with Parkinson's disease maintaining independent living and quality of life. Parkinson's disease imposes a challenging constellation of symptoms and no summary of effective interventions for carers and their unique support needs exists. Data sources., Thirty electronic databases were searched from their inception to July 2006, and bibliographies and specific internet sites were scanned. Methods., Eligible studies were categorized according to design, type of economic evaluation where applicable, number of participants, country of evaluation, intervention, orientation, provider, setting, method of delivery, carer population, patient population, carer outcomes, patient outcomes and authors' conclusions. Data were extracted by one reviewer and checked by another reviewer; discrepancies were resolved through discussion or arbitration by a third reviewer. Findings., Thirty studies met the inclusion criteria. Most investigated relatively unique interventions involving multiple elements; the majority were not aimed primarily at carers but were embedded in patient treatment programmes. Many were pilot studies, employing weak research designs and involving very small numbers of participants and most were not designed to assess the clinical or cost effectiveness of the intervention for the carers. Conclusion., Several interventions merit further investigation but there is currently little evidence to show which approaches are effective and cost effective in supporting carers. Future studies need to employ appropriate and rigorous research designs with adequate samples and outcome measures, and with more focus on the carer. [source]


    Feeding and dementia: a systematic literature review

    JOURNAL OF ADVANCED NURSING, Issue 1 2006
    Roger Watson PhD RN FIBiol FRSA
    Aim., This paper reports a systematic review of the literature on interventions to promote oral nutritional intake of older people with dementia and feeding difficulty between 1993 and 2003. Background., Older people with dementia commonly experience difficulty with feeding, especially in the later stages of the condition. This topic and related nursing care was reviewed in 1993 and the conclusion was that there was little research into interventions that nurses could use to alleviate feeding difficulty. Method., A systematic review of the literature was carried out using the CINAHL, Medline, EMBASE and Cochrane databases and the search terms ,feeding', ,eating' and ,dementia' combined as follows: ,(feeding or eating) and (dementia)'. A second search was carried out combining the search terms ,mealtimes' and ,dementia' as follows: ,mealtimes and dementia'. The literature search was carried out on 1 December 2003 and papers were included in the review if retrieved by 31 December 2003. English language papers only were retrieved. Results., Sixty-seven papers were retrieved, of which 13 addressed interventions aimed at helping older people with dementia to feed. All studies reported positive outcomes but only one randomized controlled trial was reported. Music was the most common intervention but there were no standardized interventions or outcomes across the studies and none reported the use of power analysis to decide on sample size. There were problems in some studies with confounding variables. Conclusions., Further research is needed into interventions aimed at how nurses can help older people with dementia to feed. There are some promising lines of enquiry, with music being one of these, but future studies need to use adequate samples and to use power calculations and account adequately for confounding variables. There is also a need to standardize interventions and outcomes across such studies to facilitate meta-analysis. [source]


    A systematic review on the clinical diagnosis of gastrointestinal stromal tumors

    JOURNAL OF SURGICAL ONCOLOGY, Issue 5 2008
    Marco Scarpa MD
    Abstract Background The aim of this work was to assess the prevalence of symptoms of gastrointestinal stromal tumors (GISTs) and the diagnostic yield of clinical procedures for its diagnosis. Methods Medical databases were consulted between 1998 and 2006 for potentially relevant publications. All studies dealing with the clinical presentation of GIST and related diagnostic procedures were included. Two researchers worked independently on the study selection, quality assessment, data extraction, and analysis phases of the study. Results Forty-six observational studies were included with a total of 4,534 patients. Gastrointestinal bleeding was the most common clinical presentation. Twenty studies provided adequate information on the diagnostic yield of various procedures. The pooled diagnostic yield of endoscopy,+,mucosal biopsy and of intestinal contrast radiography was 33.8% (0,100%) and 35.1% (11,100%), respectively, while that of EUS and that of EUS-FNA was 68.7% (40,100%) and 84.0% (73.8,100%), respectively. Abdominal CT scan and MRI had similar pooled diagnostic yields: 73.6% (34.8,100%), and 91.7% (75,100%), respectively. Conclusion Endoscopy,+,mucosal biopsy should be reserved to patients with gastrointestinal bleeding. EUS-FNA provides direct visualization of the neoplasm and adequate samples for molecular diagnosis. EUS, abdominal CT and MRI may be considered valid alternatives whenever EUS-FNA is unavailable or a cytological diagnosis is unnecessary. J. Surg. Oncol. 2008;98:384,392. © 2008 Wiley-Liss, Inc.

    Genetics and delusional disorder

    BEHAVIORAL SCIENCES & THE LAW, Issue 3 2006
    Alastair G. Cardno M.B., M.R.C.Psych., Ph.D.
    This article gives an overview of genetic research approaches and their application to delusional disorder. Most studies have been based on small samples and have had other methodological limitations, so it is not clear whether there is a genetic contribution to the aetiology of delusional disorder. It is unlikely that delusional disorder is strongly related genetically to affective disorder or schizophrenia, but more subtle relationships cannot be ruled out. The rarity of multiply affected families prohibits linkage studies and, to date, molecular genetic investigations have been mainly limited to small association studies of dopamine receptor polymorphisms. A range of considerably larger, epidemiologically rigorous studies is required, but the uncommonness and other features of the disorder put strong limitations on the prospects for ascertaining adequate samples.
