BACKGROUND: Atherosclerosis begins early in life. Infections might contribute to the pathogenesis of atherosclerosis. In this study, we investigated whether acute infections in children could alter the carotid wall morphology and the lipid profile. METHODS: Mean carotid intima-media thickness (IMT) was measured by high-resolution ultrasound in 28 hospitalised children (mean age: 5+/-2 years), who fulfilled the diagnostic criteria of acute infections (body temperature, >38 degrees C; C-reactive protein, >15mg/ml, and clinical), and in 20 age- and gender-matched controls. Antibodies against oxidised low-density lipoprotein (anti-oxLDL antibodies), as well as total and high-density lipoprotein cholesterol (HDL-C) were analysed in all children. The infection group was investigated both during the acute illness and 3 months after clinical recovery (post-infection). RESULTS: During the acute illness, the infection group had elevated anti-oxLDL antibodies and decreased HDL-C, as compared to those obtained at 3 months and in controls (p<0.05). These changes in the infection group were followed, at 3 months, by thickening of carotid intima-media. Those who received antibiotics during their acute illness had less carotid thickening than those who were not treated with antibiotics (p<0.05). CONCLUSION: Acute infections in children seem to be accompanied by enhanced oxidative modification of LDL and by decrease in HDL-C. These lipid changes may be followed by thickening of carotid artery intima-media. These findings suggest that, in childhood, acute infections could be associated with increased risk of atherosclerosis, and warrant further studies on this topic. 相似文献

Human resources and access to maternal health care. 总被引:5,自引:0,他引:5

The lack of human resources is one of the main bottlenecks to achieving the Millennium Development Goals on maternal and child health. A coherent national policy, recognized across government, needs to be in place to overcome this especially in countries severely affected by HIV/AIDS. Such a policy should cover selection of pre-service students, the qualifications of trainers and training sites, supportive supervision, career path development, a package of carefully thought-out incentives for the retention of staff, strategies for interaction with communities, and an agreed-upon health staff HIV/AIDS policy. Without such coherent human resource planning, a large number of countries will fail to reduce maternal and newborn mortality. 相似文献

For women and children, especially those who are poor and disadvantaged, to benefit from primary health care, they need to access and use cost-effective interventions for maternal, newborn, and child health. The challenge facing weak health systems is how to deliver such packages. Experiences from countries such as Iran, Malaysia, Sri Lanka, and China, and from projects in countries like Tanzania and India, show that outcomes in maternal, newborn, and child health can be improved through integrated packages of cost-effective health-care interventions that are implemented incrementally in accordance with the capacity of health systems. Such packages should include community-based interventions that act in combination with social protection and intersectoral action in education, infrastructure, and poverty reduction. Interventions need to be planned and implemented at the district level, which requires strengthening of district planning and management skills. Furthermore, districts need to be supported by national strategies and policies, and, in the case of the least developed countries, also by international donors and other partners. If packages for maternal, newborn and child health care can be integrated within a gradually strengthened primary health-care system, continuity of care will be improved, including access to basic referral care before and during pregnancy, birth, the postpartum period, and throughout childhood. 相似文献

Objective: To establish the effect of self-rated and measured functional hearing on depression, taking age and gender into account. Additionally, the study investigates if hearing-aid usage mitigates the effect, and if other physical health problems and social engagement confound it. Design: Cross-sectional data from the UK Biobank resource, including subjective and behavioural measures of functional hearing and multifactorial measures of depressive episodes and symptoms, were accessed and analysed using multi-regression analyses. Study sample: Over 100 000 community-dwelling, 39–70 year-old volunteers. Results: Irrespective of measurement method, poor functional hearing was significantly (p < 0.001) associated with higher levels of depressive episodes (≤ 0.16 factor scores) and depressive symptoms (≤ 0.30 factor scores) when controlling for age and gender. Associations were stronger for subjective reports, for depressive symptoms, and the younger participants. Females generally reported higher levels of depression. Hearing-aid usage did not show a mitigating effect on the associations. Other physical health problems particularly partially confounded the effects. Conclusion: Data support an association between functional hearing and depression that is stronger in the younger participants (40–49 years old) and for milder depression. The association was not alleviated by hearing-aid usage, but was partially confounded by other physical health problems. 相似文献

Most rating scales for affective disorders measure either depressive or hypomanic/manic symptoms and there are few scales for hypomania/mania in a self-rating format. We wanted to develop and validate a self-rating scale for comprehensive assessment of depressive, manic/hypomanic and mixed affective states. We developed an 18-item self-rating scale starting with the DSM-IV criteria for depression and mania, with subscales for depression and mania. The scale was evaluated on 61 patients with a diagnosis of affective disorder, predominantly bipolar disorder type I, using Montgomery–Åsberg Depression Rating Scale (MADRS), Hypomania Interview Guide—Clinical version (HIGH-C) and Clinical Global Impression scale, modified for bipolar patients (CGI-BP) as reference scales. Internal consistency of the scale measured by Cronbach's alpha was 0.89 for the depression subscale and 0.91 for the mania subscale. Spearman's correlation coefficients (two-tailed) between the depression subscale and MADRS was 0.74 (P<0.01) and between mania subscale and HIGH-C 0.80 (P<0.01). A rotated factor analysis of the scale supported the separation of symptoms in the mania and depression subscale. We established that the self-rating scales sensitivity to identify mixed states, with combined cut-offs on the MADRS and HIGH-C as reference, was 0.90 with a specificity of 0.71. The study shows that the Affective Self Rating Scale is highly correlated with ratings of established interview scales for depression and mania and that it may aid the detection of mixed affective states. 相似文献

Public awareness in Nicaragua regarding domestic violence has undergone a profound transformation in the last few years. Once viewed as a private problem affecting few women, it is now considered a major social problem. This is largely due to the work of a broad-based movement spearheaded by the National Network of Women Against Violence, which includes over 150 women's groups and hundreds of individual women all over the country. This Network conducted a year-long campaign which culminated in the passage of a new Domestic Violence Law in 1996. The process of drafting, lobbying and mobilising support for the new law was successful due to the creation of strategic alliances with politicians, government officials, community leaders, and professionals from a broad range of disciplines. Epidemiological and participatory research provided data that convinced policymakers of the need for reform. This paper traces the history of the anti-violence movement since the 1980s and describes the multiple strategies used to place domestic violence on the national political agenda. 相似文献
