Adipose tissue n-6 fatty acids and acute myocardial infarction in a population consuming a diet high in polyunsaturated fatty acids 总被引:3,自引:0,他引:3
Kark JD Kaufmann NA Binka F Goldberger N Berry EM 《The American journal of clinical nutrition》2003,77(4):796-802
BACKGROUND: The Jewish population of Israel consumes a diet rich in n-6 polyunsaturated fatty acids (PUFAs), principally linoleic acid. The consequences of this diet for ischemic heart disease (IHD) remain unclear. OBJECTIVE: We assessed the association of adipose tissue n-6 fatty acids, which are derived entirely from the diet, with acute myocardial infarction (AMI). DESIGN: A total of 180 cases and 492 IHD-free controls aged 25-64 were included in a population-based case-control study of Jerusalem residents hospitalized with a first AMI. Diet was assessed by the use of a food-frequency questionnaire and adipose tissue fatty acids by gas chromatography of biopsy samples taken from subcutaneous gluteal tissue. The data were analyzed by multivariate logistic regression. RESULTS: Dietary PUFAs (: 10.1% of energy) correlated (r = 0.43, P < 0.001) with adipose tissue linoleic acid, which constituted 25.6% of storage fatty acids. High intakes of linoleic acid were not associated with excess risk of AMI (age- and sex-adjusted odds ratio for the third versus the first tertile: 0.96; 95% CI: 0.62, 1.48; NS). In contrast, arachidonic acid, the long chain n-6 derivative of linoleic acid, was positively associated with AMI (age- and sex-adjusted odds ratio: 2.12; 95% CI: 1.33, 3.36; P = 0.004). With multivariate adjustment, there was no evidence for an adverse association of linoleic acid with AMI, whereas the risk associated with arachidonic acid persisted, albeit attenuated. CONCLUSIONS: A very high linoleic acid intake does not appear to confer increased risk of nonfatal AMI. Nonetheless, the increased risk associated with arachidonic acid, a finding that requires confirmation, tempers an inference that diets rich in n-6 fatty acids are safe vis-à-vis coronary health. 相似文献

WHO's Roll Back Malaria Cabinet Project (RBM) has been initiated by WHO Director-General Dr. G. Brundtland in 1998. The World Health Organization, The United Nation's Children's Fund, the United Nation's Development Programme and World Bank have joined forces to fight malaria, which kills more than one million people a year. RBM is being launched at time of growing and investment in malaria, which still remains grossly underfunded. RBM is different from previous efforts to fight malaria. The project is working not only through new tools for controlling the disease but also by involving and strengthening the health services to affected population. This pattern of activities is close to Russian version of malaria eradication programme that had been carried out with the success in the former Soviet Union in the 1950s. RBM seeks to reduce substantially the human suffering and economic losses due one of the most costly diseases. Malaria causes an estimated 300 to 500 million acute cases per year. Malaria is a disease of young and the poor, many of them children who live with no easy access to health service. RBM goal is a significant reduction--ideally halving within ten years--in the global burden of disease associated with malaria. RBM purpose is to create an environment that helps countries develop policies and implement relevant elements of RBM strategy. There are six elements to roll back malaria. They are: early detection of malaria illness; rapid treatment of those who are ill; multiple means for preventing infection; strengthening of health sector and intersectoral activities; a powerful sustained social involvement and movement; focused research for new tools and better implementation. New tools are available to combat malaria. They include among others: rapid diagnostics; new drugs (artesunates) and new means for delivery; impregnated bednets; new means for predicting epidemics (satellite mapping). WHO will be coordinating the RBM project. Endemic countries and affected populations have identified malaria as a priority health issue. Activities will cut across WHO programmes and regions to support government, to improve technical efficiency and capacity, to optimize resource allocation, utilization and mobilization. 相似文献

Survival and sequelae of meningococcal meningitis in Ghana 总被引:2,自引:0,他引:2
Hodgson A Smith T Gagneux S Akumah I Adjuik M Pluschke G Binka F Genton B 《International journal of epidemiology》2001,30(6):1440-1446
BACKGROUND: Meningococcal meningitis epidemics are frequent in the Sahel zone of Africa but there is little information on the frequency of long-term sequelae. We analysed excess mortality in the two years following the 1997 epidemic in northern Ghana and carried out a case-control study to assess sequelae in the survivors. METHODS: Two-year survival of 696 meningitis cases recorded at the War Memorial Hospital, Navrongo, was analysed using data from a demographic surveillance system. A structured questionnaire on disability and on psychiatric, neuropsychological and behavioural problems was administered to 505 of the survivors and 505 age- sex- and location-matched controls as well as to their respective relatives. Cases and controls underwent full neurological and neuropsychological examination and were evaluated for hearing impairment by audiometry. RESULTS: Survival rates after the first month following the attack were similar in cases and controls. Hearing impairment was the major sequela, and was reported in 6 per cent of cases and 2 per cent of controls (odds ratio [OR] = 3.10; 95% CI : 1.48-7.09). Audiometry detected severe and profound hearing loss in the worse affected ear (> or =70 db) in 8/496 (1.6%) survivors but in only one control. Survivors of meningitis were more likely to suffer from feelings of tiredness (OR = 1.47; 95% CI : 1.03-2.11) and were more often reported by relatives to have insomnia (OR = 2.31; 95% CI : 1.17-4.82) and daily alcohol consumption. INTERPRETATION: Meningococcal meningitis annually causes approximately 10 000 cases of deafness in sub-Saharan Africa; there is a need for early detection of affected survivors and promotion of simple hearing devices. There is a sizeable burden of depressive disorders secondary to meningitis which should be identified and looked after appropriately. 相似文献

In the Upper East Region of Ghana, considerable resources have been invested in the provision of boreholes. As part of the Ghana Vitamin A Supplementation Trials' Survival Study which was carried out in one of the districts of the Upper East Region between January 1989 and December 1991, data were collected over a period of one calendar year on the drinking water sources used by approximately 13 000 mothers/guardians of over 20 000 children and on the morbidity and mortality experiences of these children. These data were used to describe seasonal and geographical variations in drinking water sources; to look for other predictors of water source use; and to establish whether the drinking water source was associated with the risk of child death or the period prevalence of diarrhoea among young children.
Boreholes were used as the main source of drinking water by about 60–70% of respondents. They were used slightly more frequently in the dry season. In the rainy season, the use increased of more traditional sources such as rainwater or holes dug in stream beds. The use of boreholes was greatest in the northern zone of the study area and was more common in those who had had some formal education and were of higher socioeconomic status. Some association was found between reported drinking water source and diarrhoeal morbidity, although this association appeared to be seasonal. No significant association was found between drinking water source and child mortality. 相似文献

This study presents a focus group investigation of reasons why women in a rural, Sahelian community are reluctant to adopt family planning even when convenient services are made freely available. First, women opting to practice contraception must do so at considerable risk of social ostracism or familial conflict. Implementing individual preference is something that must be done without the support of others. Second, few women view personal decisions about contraceptives as theirs to make. Women and children are the property of the corporate family-kin and community militate against reproductive control. Third, although children are highly valued for a variety of economic, social, and cultural reasons, mortality risks remain extremely high. Low fertility imposes the unacceptable risk that a woman will have no surviving children at the end of her reproductive life. Taken together, these findings attest to the inadequacy of service strategies focused on the contribution of distribution, individual agency, or personal choice. Outreach should also build a sense of community legitimacy for the program, collective health action, and traditional leadership support for family planning behavior. 相似文献

Impact of permethrin impregnated bednets on child mortality in Kassena-Nankana district, Ghana: a randomized controlled trial 总被引:2,自引:7,他引:2
F. N. Binka A. Kubaje M. Adjuik L. A. Williams C. Lengeler G. H. Maude G. E. Armah B. Kajihara J. H. Adiamah P. G. Smith 《Tropical medicine & international health : TM & IH》1996,1(2):147-154
A community-based randomized, controlled trial of permethrin impregnated bednets was carried out in a rural area of northern Ghana, between July 1993 and June 1995, to assess the impact on the mortality of young children in an area of intense transmission of malaria and no tradition of bednet use. The district around Navrongo was divided into 96 geographical areas and in 48 randomly selected areas households were provided with permethrin impregnated bednets which were re-impregnated every 6 months. A longitudinal demographic surveillance system was used to record births, deaths and migrations, to evaluate compliance and to measure child mortality. The use of permethrin impregnated bednets was associated with 17% reduction in all-cause mortality in children aged 6 months to 4 years (RR=0.83; 95% CI 0.69–1.00; P=0.05). The reduction in mortality was confined to children aged 2 years or younger, and was greater in July-December, during the wet season and immediately after (RR=0.79; 95% CI 0.63–1.00), a period when malaria mortality is likely to be increased, than in the dry season (RR=0.92, 95% CI 0.73–1.14). The ready acceptance of bednets, the high level of compliance in their use and the subsequent impact on all-cause mortality in this study has important implications for programmes to control malaria in sub-Saharan Africa. 相似文献

After an epidemic of serogroup A meningococcal meningitis in northern Ghana, a gradual disappearance of the epidemic strain was observed in a series of five 6-month carriage surveys of 37 randomly selected households. As serogroup A Neisseria meningitidis carriage decreased, an epidemic of serogroup X meningococcal carriage occurred, which reached 18% (53/298) of the people sampled during the dry season of 2000, coinciding with an outbreak of serogroup X disease. These carriage patterns were unrelated to that of Neisseria lactamica. Multilocus sequence typing and pulsed-field gel electrophoresis of the serogroup X bacteria revealed strong similarity with other strains isolated in Africa during recent decades. Three closely related clusters with distinct patterns of spread were identified among the Ghanian isolates, and further microevolution occurred after they arrived in the district. The occurrence of serogroup X outbreaks argues for the inclusion of this serogroup into a multivalent conjugate vaccine against N. meningitidis. 相似文献
