    Binka Aji Wibowo, Saiful Manan, in paper use PMT coupling as load transfer in Sayung District Substation, Demak explain that to meet the reliability of the distribution system , it is necessary to do a continuity in the distribution of electrical energy. There are various causes of outages ranging from maintenance to interference. To resolved these problems, there are several solutions that can be done, such as transfer transformer load through PMT coupling. This can be done by connecting the two busbars by using a PMT. In operation the PMT coupling need to do prior preparation, among others, the daily load calculations. It is intended to carry transformer load does not exceed setting value

    Mortality in a seven-and-a-half-year follow-up of a trial of insecticide-treated mosquito nets in Ghana

    A 17% efficacy in preventing all-cause mortality in children aged 6-59 months was previously reported from a cluster-randomized controlled trial of insecticide-treated mosquito nets (ITNs) carried out in the Kassena-Nankana District of northern Ghana from July 1993-June 1995. A follow-up until the end of 2000 found no indication in any age group of increased mortality in the ITN group after the end of the randomized intervention. These results should further encourage the use of ITNs as a malaria control tool in areas of high endemicity of Plasmodium falciparu

    The announcement by the Ghana Health Service /Ministry of Health at the beginning of May to begin the pilot implementation of the malaria vaccine – RTS,S/AS01 (Mosquirix®) – manufactured by GSK Biologicals was greeted with rumours about conspiracy theories of secretagenda to depopulate Africa through the use of vaccines and all the other stories that are often propagated by the anti vaxxers. This was not unlike the fear and panic spread throughout the country that prevented investigators from conducting clinical trials on new vaccines against the Ebola virus disease a few years ago

    Accelerating reproductive and child health program development: The Navrongo initiative in Ghana

    Get PDF
    Successive global health and development agendas have been embraced by African governments—Alma Ata in 1978, the Bamako Initiative in 1987, the 1994 Cairo International Conference on Population and Development, and more recently the Millennium Development Goals (MDGs)—only to be followed by widespread implementation failure. This paper presents an approach to program development in Ghana that is using research to accelerate policy implementation. Originally launched in 1994 as a participatory pilot project of the Navrongo Health Research Centre, a controlled experimental study was initiated in 1996 to assess the fertility and child-survival impact of alternative community health and family planning service strategies. Posting nurses to communities reduced childhood mortality rates by half, accelerating attainment of the childhood-survival MDG within five years. Adding community-mobilization strategies and volunteer outreach to this approach led to a 15-percent reduction in fertility. When a replication project in the Volta Region demonstrated that the Navrongo service model could be transferred to a nonresearch setting, the Government of Ghana adopted the Navrongo approach as the health component of its national poverty-reduction strategy. In 2000, the Community-based Health Planning and Services (CHPS) initiative was launched to accelerate implementation of this policy. By mid-2005, CHPS was fully operational in 20 districts and under development in nearly every other district of Ghana. Analysis of successive phases of the Ghana program-development process demonstrates feasible means of improving national access to reproductive and child health services

    For some time, Chinese government policies have treated rural and urban areas very differently, and a by-product of China’s rapid development seems to be an even greater differentiation between urban and rural social and economic life. Over the next several decades, in part because of rapid fertility declines and in part as a result of mortality declines at older ages, China and other developing countries will experience enormous increases in the proportion of older adults and the proportion of the “oldest-old.” It is reasonable to expect that these age structure changes will alter the provision of health care, making an understanding of the determinants of health at older ages critical for the development and implementation of policy. The analysis in this Population Council working paper describes differences in mortality and examines the extent to which variations are accounted for by socioeconomic and health-access and health-availability characteristics that are measured at individual and community levels. On the individual level, cadre status is influential and at the community level, the important measure is the number of amenities available to residents

    The impact of immunization on the association between poverty and child survival: Evidence from Kassena-Nankana District of northern Ghana

    Get PDF
    Research conducted in Africa has demonstrated consistently that parental poverty and low educational attainment adversely affect child survival. Relative poverty has a pronounced effect on the survival of children, even in a setting where nearly all families are poor. Results from the research presented in the working paper lend strong support to the United Nations’ goal of reducing excess childhood mortality among the poor by directing a particular focus on immunization. Findings in this working paper show that the adverse effects of poverty disappear and that the effects of educational attainment are reduced in survival models that control for immunization status. This finding lends empirical support to policies that promote immunization as a strategic component of poverty-reduction programs

    Efficacious, effective, and embedded interventions: Implementation research in infectious disease control

    Get PDF
    Background: Research in infectious disease control is heavily skewed towards high end technology; development of new drugs, vaccines and clinical interventions. Oft ignored, is the evidence to inform the best strategies that ensure the embedding of interventions into health systems and amongst populations. In this paper we undertake an analysis of the challenge in the development of research for the sustainable implementation of disease control interventions. Results: We highlight the fundamental differences between the research paradigms associated with the development of technologies and interventions for disease control on the one hand and the research paradigms required for enhancing the sustainable uptake of those very same interventions within the communities on the other. We provide a definition for implementation research in an attempt to underscore its critical role and explore the multidisciplinary science needed to address the challenges in disease control. Conclusion: The greatest value for money in health research lies in the sustainable and effective implementation of already proven, efficacious solutions. The development of implementation research that can help provide some solutions on how this can be achieved is sorely needed

    Prospective Study of a Serogroup X Neisseria meningitidis Outbreak in Northern Ghana

    Get PDF
    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. meningitidi

    Characteristics of severe anemia and its association with malaria in young children of the Kassena-Nankana District of northern Ghana.

    Severe anemia is thought to be the principal underlying cause of malaria death in areas of intense seasonal malaria transmission such as the Kassena-Nankana District of northern Ghana. Factors associated with severe anemia in young children, 6-24 months old, were elucidated by analyzing results of 2 malaria-associated anemia surveys (1996, 2000), separated by 4 years, but conducted in the same community and at the same seasonal time point. Age-adjusted comparison confirmed that the proportion of severely anemic children and overall mean hemoglobin (Hb) levels in the November 2000 sample were significantly improved over those of the 1996 sample (17.5 versus 26.4%, P = 0.03; Hb 7.5 versus 6.9 g/dL, P = 0.002). Weight-for-age Z-scores also indicated a significant improvement in the 2000 sample (-1.93 versus -2.20, P or = 6.0 g/dL, those with severe anemia (Hb < 6.0 g/dL) were older, more frequently parasitemic (odds ratio [OR], 1.60; 95% confidence interval [CI], 1.08-2.35), more often febrile (OR, 2.44; 95% CI, 1.71-3.48), and predominantly male (OR, 1.50; 95% CI, 1.05-2.13). An association was identified in both surveys between severe anemia and residence in the northern part of the district, but no clear link was observed in relation to irrigation. Blood transfusions, a likely surrogate index of severe anemia in young children, followed a distinct seasonal pattern. Evidence suggests that dramatic peaks and troughs of severe anemia are regular and possibly predictable events that may be used to gauge the health and survival of young children in this area

    BACKGROUND: Malaria remains the leading cause of morbidity and mortality in sub-Saharan Africa despite tools currently available for its control. Making malaria vaccine available for routine use will be a major hallmark, but its acceptance by community members and health professionals within the health system could pose considerable challenge as has been found with the introduction of polio vaccinations in parts of West Africa. Some of these challenges may not be expected since decisions people make are many a time driven by a complex myriad of perceptions. This paper reports knowledge and perceptions of community members in the Kintampo area of Ghana where malaria vaccine trials have been ongoing as part of the drive for the first-ever licensed malaria vaccine in the near future. METHODS: Both qualitative and quantitative methods were used in the data collection processes. Women and men whose children were or were not involved in the malaria vaccine trial were invited to participate in focus group discussions (FGDs). Respondents, made up of heads of religious groupings in the study area, health care providers, traditional healers and traditional birth attendants, were also invited to participate in in-depth interviews (IDIs). A cross-sectional survey was conducted in communities where the malaria vaccine trial (Mal 047RTS,S) was carried out. In total, 12 FGDs, 15 IDIs and 466 household head interviews were conducted. RESULTS: Knowledge about vaccines was widespread among participants. Respondents would like their children to be vaccinated against all childhood illnesses including malaria. Knowledge of the long existing routine vaccines was relatively high among respondents compared to hepatitis B and Haemophilus influenza type B vaccines that were introduced more recently in 2002. There was no clear religious belief or sociocultural practice that will serve as a possible barrier to the acceptance of a malaria vaccine. CONCLUSION: With the assumption that a malaria vaccine will be as efficacious as other EPI vaccines, community members in Central Ghana will accept and prefer malaria vaccine to malaria drugs as a malaria control tool. Beliefs and cultural practices as barriers to the acceptance of malaria vaccine were virtually unknown in the communities surveyed
