    A Research Report Submitted to the School of Public Health, Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the Degree of Master of Science in Medicine in Tropical Diseases (Epidemiology and Biostatistics Option). Johannesburg, January 2001Background: increasing spread of drug resistance among Plasmodium falciparum poses a serious threat to malaria treatment. The situation is complicated not only because new drugs are expensive and slow in development but also because they must be effective, preferably have a novel method of action, with an acceptable level of adverse effects, and be deployed in such a way as to prolong their use.IT201

    Sustainable Pathway for Closing Solid Waste Data Gaps: Implications for Modernization Strategies and Resilient Cities in Developing Countries

    Get PDF
    This chapter addresses three peculiar challenges in the solid waste management system of developing countries, namely: the chronic lack of reliable data for planning purposes, the absence of participatory engagement strategies in data gathering for wider ownership and usage, and the lack of monitoring of the climate change burden of existing waste disposal practices. A team of researchers has collaborated with system managers and a responsible philanthropic organization to engage key stakeholders to address these gaps in a sustainable manner. The strategy deployed has been to work in a participatory and evidenced-based frame to solicit support, enhance capacities, empower each other to understand the problems and find for ourselves the practical routes by which solid waste data gaps can be closed in the greater Accra region of Ghana. Stakeholders have participated in a comprehensive waste audit and landfill emission monitoring exercise to develop a baseline, and have used local resources and ideas to recommend steps to sustain reliable data flows and the development of a climate action plan for purposes of modernization. The methodological processes and research outcomes suggest that structural collaboration between researchers and system stakeholders is necessary to break the vicious circle of chronic data gaps and substitute virtuous circles of reliable data for planning purposes

    INTRODUCTION: Clinical trials conducted in sub-Saharan Africa have helped to address the prevalent health challenges. The knowledge about how communities perceive clinical trials is however only now evolving. This study was conducted among parents whose children participated in past clinical trials in northern Ghana to assess their knowledge and perceptions of clinical trials and the use of biomedical samples. METHOD: This was a qualitative study based on eighty in-depth interviews with parents. The participants were randomly selected from among parents whose children were enrolled in a clinical trial conducted in the Kassena-Nankana districts between 2000 and 2003. The interviews were transcribed and coded into emergent themes using Nvivo 9 software. The thematic analysis framework was used to analyze the data. RESULTS: Study participants reported that clinical trials were carried out to determine the efficacy of drugs and to make sure that these drugs were suitable for human beings to use. The conduct of clinical trials was perceived to have helped to reduce the occurrence of diseases such as malaria, cerebrospinal meningitis and diarrhea. Quality of care was reported to be better in clinical trials than in the routine care. Parents indicated that participation in clinical trials positively influenced their health-seeking behavior. Apprehensions about blood draw and the use to which samples were put were expressed, with suspicion by a few participants that researchers sold blood samples. The issue of blood draw was most contentious. CONCLUSION: Parents perception about the conduct of clinical trials in the study districts is generally positive. However, misconceptions made about the use of blood samples in this study must be taken seriously and strategies found to improve transparency and greater community acceptability

    BACKGROUND: Health facility data are more readily accessible for operational planning and evaluation of disease control programmes. The importance, potential challenges and limitations of using facility based survey as an alternative tool for monitoring changes in local malaria epidemiology were examined. METHODS: The study involved six areas within the administrative divisions of The Gambia. The areas were selected to reflect socioeconomic and malaria transmission intensities across the country. The study design involved an age stratified cross sectional surveys that were conducted during the wet season in 2008 and in the 2009 during the dry season. Participants were patients attending clinics in six health centres and the representative populations from the catchment communities of the health centres. RESULTS: Overall participants' characteristics were mostly not comparable in the two methodological approaches in the different seasons and settings. More females than males were enrolled (55.8 vs. 44.2 %) in all the surveys. Malaria infection was higher in the surveys in health centres than in the communities (p < 0.0001) and also in males than in females (OR = 1.3; p < 0.001). Males were less likely than females to sleep under an insecticide treated net in the communities (OR = 1.6; 95 % CI 1.3, 1.9) and in the health centres (OR = 1.3; 95 % CI 1.1, 1.5). Representativeness of the ethnic groups was better in the health centre surveys than in the community surveys when compared to the 2003 national population census in The Gambia. CONCLUSION: Health facility based survey though a potential tool for monitoring changes in the local epidemiology of malaria will require continuous validation of the facility and participants sociodemograhic characteristics as these may change over time. The effects of health seeking practices on service utilization and health facility surveys as an approach will also need continuous review

    BACKGROUND: Malaria is a major public health problem in Ghana. The current strategy of the National Malaria Control Programme is based on effective case management and the use of insecticide treated bed nets among vulnerable groups such as children under-five years of age and pregnant women. Resistance to pyrethroids by Anopheles gambiae s.l. and Anopheles funestus has been reported in several African countries including neighbouring Burkina Faso. METHODS: Indoor resting Anopheles mosquitoes were collected. Blood-fed and gravid females were allowed to oviposit, eggs hatched and larvae reared to 1-3 days old adults and tested against permethrin 0.75%, deltamethrin 0.05%, cyfluthrin 0.15%, lambdacyhalothrin 0.1% and DDT 4%, based on WHO methodology. PCR analyses were carried out on a sub-sample of 192 of the An. gambiae for sibling species complex determination. Resistance to pyrethroids and DDT was determined by genotyping the knock-down resistance kdr gene mutations in the study area. RESULTS: A total of 9,749 1-3 days-old F1 female Anopheles mosquitoes were exposed to the insecticides. Among the pyrethroids, permethrin, 0.75% had the least knockdown effect, whilst cyfluthrin 0.15%, had the highest knock-down effect. Overall, no difference in susceptibility between An. gambiae 93.3% (95% CI: 92.5-94.1) and An. funestus 94.5% (95% CI: 93.7-95.3) was observed when exposed to the pyrethroids. Similarly, there was no difference in susceptibility between the two vector species (An. gambiae = 79.1% (95% CI: 76.6-81.8) and An. funestus = 83.5% (95% CI: 80.2-86.4) when exposed to DDT. Overall susceptibility to the insecticides was between 80% and 98%, suggesting that there is some level of resistance, except for cyfluthrin 0.15%. The kdr PCR assay however, did not reveal any kdr mutations. The analysis also revealed only the molecular M (Mopti) form. CONCLUSION: The findings in this study show that An. gambiae and An. funestus, the main malaria vector mosquitoes in the Kassena-Nankana district are susceptible to the insecticides being used in the treatment of bed nets in the malaria control programme. There is however, the need for continuous monitoring of the pyrethroids as the efficacy is not very high

    BACKGROUND: During the last decade, the number of clinical trials conducted in sub-Saharan Africa has increased significantly which has helped to address priority health problems in the region. Navrongo health research centre since it was established in 1989, has conducted several trial studies including rectal artesunate trial in the Kassena-Nankana districts. However, there is little evidence-based for assessing the impact of new drug trials. This study explored factors that motivate parents to allow their children to participate in new drug trials in northern Ghana. METHOD: The study used both quantitative and qualitative methods. The participants were randomly selected from among parents whose children were enrolled in a new drug trial conducted in the Kassena-Nankana districts between 2000 and 2003. QSR Nvivo 9 software was used to code the qualitative data into themes before analysis while STATA software Version 11.2© was used to analyze the quantitative data. RESULTS: The results showed that majority (95.9%) of the parents were willing to allow their children to be enrolled in future new drug trials. The main factors motivating their willingness to allow their children to be enrolled in these trials were quality of health care services offered to trial participants (92.9%), detail medical examination (90.8%), promptness of care provided (94.4%) and quality of drugs (91.9%). Other factors mentioned included disease prevention (99.5%) and improved living standard (96.1%). Parents reported that the conduct of these trials had reduced the frequency of disease occurrences in the communities because of the quality of health care services provided to the children recruited into these trial studies. CONCLUSION: Though the implementation of clinical trials in the study area is believed to have positive impact on health status of people particularly trial participants, measures should however be taken to address safety and likely side effects of new drugs given to trial participants during these trial studies

    PREventing Maternal And Neonatal Deaths (PREMAND): a study protocol for examining social and cultural factors contributing to infant and maternal deaths and near-misses in rural northern Ghana

    Full text link
    Plain English Summary The Preventing Maternal And Neonatal Deaths (PREMAND) project works to understand the social and cultural factors that may contribute to the deaths and near-misses (people who almost die but end up surviving) of mothers and babies in four districts in Northern Ghana. Examples of these factors include such thing as treating a sick baby at home with traditional medicine instead of going to a hospital or health center, or pregnant women needing permission from several people before they can go to a hospital to deliver. These social and cultural factors will be placed on a map to understand where patterns and clusters of deaths and near-misses are present in these four communities. The final phase of the project will include support and small grants for community members and local leaders to use these maps and this information to create their own solutions that address the specific needs of each community. Abstract Background While Ghana is a leader in some health indicators among West African nations, it still struggles with high maternal and neonatal morbidity and mortality rates, especially in the northern areas. The clinical causes of mortality and morbidity are relatively well understood in Ghana, but little is known about the impact of social and cultural factors on maternal and neonatal outcomes. Less still is understood about how such factors may vary by geographic location, and how such variability may inform locally-tailored solutions. Methods/Design Preventing Maternal And Neonatal Deaths (PREMAND) is a three-year, three-phase project that takes place in four districts in the Upper East, Upper West, and Northern Regions of Ghana. PREMAND will prospectively identify all maternal and neonatal deaths and ‘near-misses’, or those mothers and babies who survive a life threatening complication, in the project districts. Each event will be followed by either a social autopsy (in the case of deaths) or a sociocultural audit (in the case of near-misses). Geospatial technology will be used to visualize the variability in outcomes as well as the social, cultural, and clinical predictors of those outcomes. Data from PREMAND will be used to generate maps for local leaders, community members and Government of Ghana to identify priority areas for intervention. PREMAND is an effort of the Navrongo Health Research Centre and the University of Michigan Medical School. Discussion PREMAND uses an innovative, multifaceted approach to better understand and address neonatal and maternal morbidity and mortality in northern Ghana. It will provide unprecedented access to information on the social and cultural factors that contribute to deaths and near-misses in the project regions, and will allow such causal factors to be situated geographically. PREMAND will create the opportunity for local, regional, and national stakeholders to see how these events cluster, and place them relative to traditional healer compounds, health facilities, and other important geographic markers. Finally, PREMAND will enable local communities to generate their own solutions to maternal and neonatal morbidity and mortality, an effort that has great potential for long-term impact.http://deepblue.lib.umich.edu/bitstream/2027.42/134530/1/12978_2016_Article_142.pd

    Prevalence and factors associated with female genital mutilation among women of reproductive age in the Bawku municipality and Pusiga District of northern Ghana

    Full text link
    Abstract Background Globally, three million girls are at risk of female genital mutilation (FGM) and an estimated 200 million girls and women in the world have undergone FGM. While the overall prevalence of FGM in Ghana is 4%, studies have shown that the overall prevalence in the Upper East Region is 38%, with Bawku municipality recording the highest at 82%. Methods This study used a cross-sectional design with a quantitative approach: a survey with women of reproductive age (15–49). Results Among all respondents, 830 women who participated in the study, 61% reported having undergone FGM. Of those circumcised, 66% indicated their mothers influenced it. Three quarters of the women think FGM could be stopped through health education. Women who live in the Pusiga district (AOR: 1.66; 95% CI: 1.16–2.38), are aged 35–49 (AOR: 4.24; 95% CI: 2.62–6.85), and have no formal education (AOR: 2.78; 95% CI: 1.43–5.43) or primary education (AOR: 2.10; 95% CI: 1.03–4.31) were more likely to be circumcised relative to those who reside in Bawku Municipal, are aged 15–24, and had tertiary education. Likewise, married women (AOR: 3.82; 95% CI: 2.53–5.76) were more likely to have been circumcised compared with unmarried women. At a site-specific level, factors associated with FGM included age and marital status in Bawku, and age, marital status, and women’s education in Pusiga. Conclusion Female Genital Mutilation is still being practiced in the Bawku Municipality and the Pusiga District of northern Ghana, particularly among women with low socio-economic status. Implementing interventions that would provide health education to communities and promote girl-child education beyond the primary level could help end the practice.https://deepblue.lib.umich.edu/bitstream/2027.42/145688/1/12905_2018_Article_643.pd

    Male involvement in maternal health: perspectives of opinion leaders

    Get PDF
    https://doi.org/10.1186/s12884-017-1641-9Background Twenty years after acknowledging the importance of joint responsibilities and male participation in maternal health programs, most health care systems in low income countries continue to face challenges in involving men. We explored the reasons for men’s resistance to the adoption of a more proactive role in pregnancy care and their enduring influence in the decision making process during emergencies. Methods Ten focus group discussions were held with opinion leaders (chiefs, elders, assemblymen, leaders of women groups) and 16 in-depth interviews were conducted with healthcare workers (District Directors of Health, Medical Assistants in-charge of health centres, and district Public Health Nurses and Midwives). The interviews and discussions were audio recorded, transcribed into English and imported into NVivo 10 for content analysis. Results As heads of the family, men control resources, consult soothsayers to determine the health seeking or treatment for pregnant women, and serve as the final authority on where and when pregnant women should seek medical care. Beyond that, they have no expectation of any further role during antenatal care and therefore find it unnecessary to attend clinics with their partners. There were conflicting views about whether men needed to provide any extra support to their pregnant partners within the home. Health workers generally agreed that men provided little or no support to their partners. Although health workers had facilitated the formation of father support groups, there was little evidence of any impact on antenatal support. Conclusions In patriarchal settings, the role of men can be complex and social and cultural traditions may conflict with public health recommendations. Initiatives to promote male involvement should focus on young men and use chiefs and opinion leaders as advocates to re-orient men towards more proactive involvement in ensuring the health of their partners.https://doi.org/10.1186/s12884-017-1641-918pubpub

    Optimizing task- sharing in abortion care in Ghana: Stakeholder perspectives

    Full text link
    Ghana has made progress in expanding providers in abortion care but access to the service is still a challenge. We explored stakeholder perspectives on task- sharing in abortion care and the opportunities that exist to optimize this strategy in Ghana. We purposively sampled 12 representatives of agencies that played a key role in expanding abortion care to include midwives for key informant interviews. All interviews were audio recorded, transcribed verbatim, and then coded for thematic analysis. Stakeholders indicated that Ghana was motivated to practice task- sharing in abortion care because unsafe abortion was contributing significantly to maternal mortality. They noted that the Ghana Health Service utilized the high maternal mortality in the country at the time, advancements in medicine, and the lack of clarity in the definition of the term - health practitioner- to work with partner nongovernmental organizations to successfully task- share abortion care to include midwives. Access, however, is still poor and provider stigma continues to contribute significantly to conscientious objection. This calls for further task- sharing in abortion care to include medical or physician assistants, community health officers, and pharmacists to ensure that more women have access to abortion care.Midwives are providing abortion care in Ghana through task- sharing; access is still limited, therefore further expansion to include physician assistants and community health nurses is needed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/156176/1/ijgo13000.pd
