  2. Development and validation of a physical model to investigate the biomechanics of infant head impact.

    Jones, M; Darwall, D; Khalid, G; Prabhu, R; Kemp, A; Arthurs, O; Theobald, P
    Head injury in childhood is the single most common cause of death or permanent disability from injury. However, despite its frequency and significance, there is little understanding of the response of a child's head to injurious loading. This is a significant limitation when making early diagnoses, informing clinical and/or forensic management or injury prevention strategies. With respect to impact vulnerability, current understanding is predominantly based on a few post-mortem-human-surrogate (PMHS) experiments. Researchers, out of experimental necessity, typically derive acceleration data, currently an established measure for head impact vulnerability, by calculation. Impact force is divided by the head mass, to produce...

  3. Preclinical transgenic and patient-derived xenograft models recapitulate the radiological features of human adamantinomatous craniopharyngioma.

    Boult, JKR; Apps, JR; Hölsken, A; Hutchinson, JC; Gabriela, C; Danielson, LS; Smith, LM; Bäuerle, T; Buslei, R; Buchfelder, M; Virasami, AK; Koers, A; Arthurs, OJ; Jacques, TS; Chesler, L; Martinez-Barbera, JP; Robinson, SP
    AIM: To assess the clinical relevance of transgenic and patient-derived xenograft models of adamantinomatous craniopharyngioma (ACP) using serial magnetic resonance imaging (MRI) and high resolution post-mortem micro-computed tomography (μ-CT), with correlation with histology and human ACP imaging. METHODS: The growth patterns and radiological features of tumours arising in Hesx1(Cre/+) ;Ctnnb1(l) °(x(ex3)/+) transgenic mice, and of patient-derived ACP xenografts implanted in the cerebral cortex, were monitored longitudinally in vivo with anatomical and functional MRI, and by ex vivo μ-CT at study end. Pathological correlates with haematoxylin and eosin stained sections were investigated. RESULTS: Early enlargement and heterogeneity of Hesx1(Cre/+) ;Ctnnb1(l) °(x(ex3)/+)...

  4. Services for children with HIV/AIDS: the views of parents.

    Barrett, G; Victor, CR
    In this qualitative study, the parents of ten children who attended an inner-London teaching hospital for HIV/AIDS were interviewed to find out their views on the services. Speaking from their own experiences, parents expressed a high level of satisfaction with the specialist paediatric care at the teaching hospital but had little confidence in the expertise of other hospitals or of GPs and health visitors. Few cases had been identified antenatally; the diagnosis of HIV/AIDS was often made only after the child had become ill and been investigated for a variety of diseases before being tested for HIV. The families felt...

  7. Evaluation of the psychometric properties of the London Measure of Unplanned Pregnancy in Brazilian Portuguese

    Borges, ALV; Barrett, G; dos Santos, OA; Nascimento, NDC; Cavalhieri, FB; Fujimori, E

  9. Improving uptake of immunisation. Mobile children miss out.

    Barrett, G; Ramsay, M

  10. Key problems in using health status measures.

    Barrett, G; Victor, CR
    This article describes the development of health status measures and the benefits to be gained from their use. The difficulties in conceptualising and quantifying health are described. The authors conclude that a critical approach to the use of health status measures is needed if these instruments are to be of benefit to health care and health research.

  11. Late diagnosis of HIV infection in children is common and devastating.

    Barrett, G; Victor, CR

  12. Sexual function after childbirth: women's experiences, persistent morbidity and lack of professional recognition.

    Barrett, G; Pendry, E; Peacock, J; Victor, CR

  13. Changes in household composition among the over sixties: a longitudinal analysis of the Health and Lifestyles Surveys.

    Pendry, E; Barrett, G; Victor, C
    Analyses of longitudinal data from the Health and Lifestyles Surveys (HALS) were carried out in order to examine the household changes of older people. Respondents who were interviewed at both the first HALS survey in 1984/85 (HALS1) and the second survey 7 years later (HALS2) and were aged 60 or over in HALS1 were selected (1156). Changes in household composition between the two surveys were examined and the relationship of these changes to socio-demographic factors and to both cross-sectional and longitudinal health factors investigated. Results of the analysis showed there was great diversity of experience and a considerable amount of...

  14. Women's sexuality after childbirth: a pilot study.

    Barrett, G; Pendry, E; Peacock, J; Victor, C; Thakar, R; Manyonda, I
    A pilot study was carried out investigating women's sexual health in the postnatal period. Postal questionnaires were sent to a cohort of 158 primiparous women approximately 7 months after delivery. Women who had resumed sexual intercourse were asked a detailed set of questions about problems experienced, sexual practices, frequency of intercourse, satisfaction with sex life, and consultation for postnatal sexual problems. All women were asked about the information they received on postnatal health prior to the birth and any information or help and advice they received from health professionals on the subject after the birth. Ninety-eight women (62%) responded. Women...

  15. Understanding pregnancy intentions: a problem in evidence everywhere.

    Barrett, G; Wellings, K

  16. Confidentiality and the public interest in medical research--will we ever get it right?

    Coleman, MP; Evans, BG; Barrett, G
    Developments over the last decade in legislation and professional guidance on confidentiality and medical research in the UK are reviewed. Despite the General Medical Council's guidance, and recent changes to the common law on confidentiality in England and Wales, confusion remains about what is lawful and professionally acceptable in the handling of identifiable data. The GMC has contributed to this confusion. Professional bodies should jointly produce new guidance. The Health and Social Care Act 2001 is a temporary legislative solution. Public consensus is required on an acceptable balance between the citizen's right to privacy and the responsibility of society--to which...

  17. Postnatal depression and sexual health after childbirth.

    Morof, D; Barrett, G; Peacock, J; Victor, CR; Manyonda, I
    OBJECTIVE: To investigate the sexual health experiences of depressed and nondepressed postnatal women within a 6-month postnatal period. METHODS: This cross-sectional study used obstetric records and postal survey 6 months after delivery from a cohort of primiparous women (n = 796) delivering a live-born infant at St. George's NHS Trust, London. Women self-reported sexual problems and sexual behaviors and completed the Edinburgh Postnatal Depression Scale. RESULTS: Of the 796 parturients, 484 responded (61%), and 468 completed the survey questions on depression and sexual health (97%). Of the latter, 57 (12%) fit the Edinburgh Postnatal Depression Scale criteria. Comparing the depressed...

  18. Conceptualisation, development, and evaluation of a measure of unplanned pregnancy.

    Barrett, G; Smith, SC; Wellings, K
    STUDY OBJECTIVE: To develop a measure of unplanned pregnancy that is valid, reliable, and appropriate in the context of contemporary demographic trends and social mores and can be used in a variety of situations, including the production of population prevalence estimates. DESIGN: A two stage study design: qualitative (inductive) methods to delineate the construct of pregnancy planning, and quantitative/psychometric methods to establish the means of measurement. SETTING: Eight health service providers (comprising 14 clinics, including antenatal, abortion, and one general practitioner) across London, Edinburgh, Hertfordshire, Salisbury, and Southampton in the UK. PARTICIPANTS: Samples comprised a mixture of pregnant (continuing pregnancy...

  19. Cesarean section and postnatal sexual health.

    Barrett, G; Peacock, J; Victor, CR; Manyonda, I
    BACKGROUND: Cesarean delivery avoids perineal trauma and has therefore often been assumed to protect sexual function after childbirth. We sought to examine this assumption by using data from a study of women's sexual health after childbirth to assess whether women who underwent cesarean section experienced better sexual health in the postnatal period than women with vaginal births. METHODS: A cross-sectional study was conducted of 796 primiparous women, employing data from obstetric records and a postal survey 6 months after delivery. RESULTS: Any protective effect of cesarean section on sexual function was limited to the early postnatal period (0-3 months), primarily...
