Knowledge and attitudes concerning medical genetics amongst physicians and medical students in Cameroon (sub-Saharan Africa)

Parents and Provider Perspectives on the Return of Genomic Findings for Cleft Families in Africa

BACKGROUND

Inadequate knowledge among health care providers (HCPs) and parents of affected children limits the understanding and utility of secondary genetic findings (SFs) in under-represented populations in genomics research. SFs arise from deep DNA sequencing done for research or diagnostic purposes and may burden patients and their families despite their potential health importance. This study aims to evaluate the perspective of both groups regarding SFs and their choices in the return of results from genetic testing in the context of orofacial clefts.

METHODS

Using an online survey, we evaluated the experiences of 252 HCPs and 197 parents across participating cleft clinics in Ghana and Nigeria toward the return of SFs across several domains.

RESULTS

Only 1.6% of the HCPs felt they had an expert understanding of when and how to incorporate genomic medicine into practice, while 50.0% agreed that all SFs should be returned to patients. About 95.4% of parents were willing to receive all the information from genetic testing (including SFs), while the majority cited physicians as their primary information source (64%).

CONCLUSIONS

Overall, parents and providers were aware that genetic testing could help in the clinical management of diseases. However, they cited a lack of knowledge about genomic medicine, uncertain clinical utility, and lack of available learning resources as barriers. The knowledge gained from this study will assist with developing guidelines and policies to guide providers on the return of SFs in sub-Saharan Africa and across the continent.

All you Need is Trust? Public Perspectives on Consenting to Participate in Genomic Research in the Sri Lankan District of Colombo

Engagement with genomic medicine and research has increased globally during the past few decades, including rapid developments in Sri Lanka. Genomic research is carried out in Sri Lanka on a variety of scales and with different aims and perspectives. However, there are concerns about participants' understanding of genomic research, including the validity of informed consent. This article reports a qualitative study aiming to explore the understanding, knowledge, and attitudes of the Sri Lankan public towards genomic medicine and to inform the development of an effective and appropriate process for informed consent in that setting. Purposive sampling was employed. Participants were recruited from a sub-group of the public in Colombo, Sri Lanka who had either consented or refused to donate genetic material for a biobank. Data were collected using face-to-face semi-structured interviews. Interview data were transcribed verbatim and translated into English. Conventional content analysis was used. The analysis developed three key themes: a) 'Scientific literacy' describes an apparent lack of scientific knowledge that seems to affect a participant's ability to understand the research, b) 'Motivation' describes narratives about why participants chose (not) to take part in the research, despite not understanding it, and c) 'Trust' describes how trust served to mitigate the apparent ethical deficit created by not being fully informed. In this article, we argue that informed trust is likely an acceptable basis for consent, particularly in settings where scientific literacy might be low. However, researchers must work to be worthy of that trust and ensure that misconceptions are actively addressed.

Understanding Challenges of Genetic Testing on Neuromuscular Disorders from the Parental Lens

Neuromuscular disorders, characterized by progressive muscle degeneration and weakness, present substantial challenges to both affected individuals and their families. Genetic testing assumes a pivotal role in facilitating early diagnosis, intervention, treatment, and informed family planning for these conditions. The objective of this qualitative study is to delve into the knowledge, awareness, and perceptions surrounding genetic testing within the cohort of parents caring for individuals with neuromuscular disorders in Malaysia. A semi-structured interview approach was employed to elicit data from parents of individuals diagnosed with neuromuscular disorders, encompassing those with clinical diagnoses and those diagnosed through genetic testing. Examination of the interview responses yielded nine overarching themes, which furnish invaluable insights into the perspectives of Malaysian parents concerning genetic testing. The study discerned several challenges associated with genetic testing, notably encompassing the limited awareness among parents, the financial constraints associated with genetic testing, and the perceived significance of genetic testing in the context of neuromuscular disorders. The findings suggest that the level of knowledge and awareness pertaining to genetic testing for neuromuscular disorders among parents in Malaysia varies, with initial levels of awareness ranging from relatively low to reasonably sufficient prior to and following the birth of an affected child. However, the investigation revealed that parents tended to cultivate more favorable perceptions regarding genetic testing subsequent to their experience with genetic counseling. This underscores the potential for heightened awareness and comprehension as a consequence of the personal experience of parenting an affected child confirmed through genetic testing and genetic counseling, ultimately influencing parental awareness.

Perceptions of Nigerian medical students regarding their preparedness for precision medicine: a cross-sectional survey in Lagos, Nigeria

BACKGROUND

Advances in precision medicine in Nigeria suggest improving genomics education and competency among healthcare practitioners to facilitate clinical translation. Due to the scarcity of research in this area, this study aimed to assess Nigerian medical students' perceptions about their preparedness to integrate precision medicine into their future clinical practice.

METHODS

This was an institution-based cross-sectional study of medicine and surgery students in their clinical years attending the two fully accredited colleges of medicine in Lagos, Nigeria, between April and October 2022 using an adapted tool administered via Google Forms. The survey assessed their awareness, perceptions about knowledge, ability, and attitudes toward precision medicine, ethical concerns, and perceptions about their education in precision medicine. Multivariate linear regression models were used to assess factors associated with students' perceptions of their knowledge, ability, and attitudes.

RESULTS

A total of 300 students completed the questionnaires with a response rate of 40%. Awareness of genomic medicine terminology was high (92.0%). Responses to knowledge and ability questions revealed notable gaps, however, respondents had positive attitude scores overall. Higher medical school year was independently associated with lower knowledge (ptrend = 0.003) and ability (ptrend = 0.005) scores, and knowledge score was independently associated with a higher ability score (β: 0.76 95%CI: 0.67, 0.84; p < 0.001). Attitude scores significantly increased with increasing medical school year (ptrend = 0.04). The respondents mostly indicated concerns about government and corporate bodies' misuse of genomic data (35.7%) and the widening of socioeconomic disparities (34.0%). Although 65.0% of the respondents thought it important to learn about precision medicine, only 11.3% felt that their education had adequately prepared them for precision medicine, knew who to ask questions regarding genomic testing (10.7%), and felt their professors had encouraged the use of precision medicine (10.3%).

CONCLUSION

Despite high awareness of precision medicine terminology and overall positive attitudes, our findings highlight gaps in knowledge and ability to integrate genomics into the care of patients and a need to improve precision medicine education among Nigerian medical students.

Indications, types, and diagnostic implications of prenatal genetic testing in Sub-Saharan Africa: A descriptive study

OBJECTIVE

To describe indications, test types, and results of prenatal diagnostic genetic amniocentesis among Ethiopian pregnant women.

METHODS

This study was a descriptive study on prenatal diagnostic genetic testing among Ethiopian pregnant women with certain indications and it was conducted at St. Paul's Hospital Millennium Medical College (Addis Ababa, Ethiopia) from January 2017 to April 2023. Data on sociodemographic characteristics, genetic testing indications, types, and results were collected electronically. Data were analysed using SPSS version 23.

RESULTS

A total of 159 cases were analysed. The commonest indication for genetic testing among the study subjects was major fetal structural anomalies identified on specialized prenatal anatomic scanning of the index pregnancy detected in 71(44.7%) cases. Down syndrome and Edward syndrome were the commonest genetic aberrations detected accounting for 6.3% (10/159) and 4.4% (7/159), respectively. Among the rare genetic aberration detected were Di-George syndrome (0.6%) and Duchenne muscular dystrophy (0.6%).

CONCLUSION

Findings of our study underscore the importance of diagnostic prenatal testing in a Sub-Saharan Africa setting, as common (trisomy 21&18) and rare genetic defects were identified using this important prenatal diagnostic testing. Considering the implications of detecting chromosomal abnormalities for future counselling and care, carrier state in parents for some chromosomal anomalies, and planning post-natal management of some abnormalities that are associated with aneuploidies (notably cardiac anomalies), initiation of diagnostic prenatal genetic testing service at tertiary public health facilities should be acted up on.

Medical students' self-perceived knowledge and clinical comfort with genetics in Pakistan

Pakistan has a high rate of genetic disorders and neonatal mortality concurrent with noted lack of genetic counselors and geneticists. To meet the needs of the patient population, the responsibility of providing clinical genetic services falls on general and specialty physicians. However, their education regarding these essential services is not standardized in medical school curricula nor has it ever been evaluated. The purpose of this work is to describe the self-perceived knowledge, clinical comfort, and perspectives of Pakistani medical students toward their medical genetics' education. A web-based survey was distributed electronically to medical schools around the country. The survey comprised of four sections: (1) participant demographics, (2) self-perceived medical genetics knowledge, (3) level of comfort in applying genetic knowledge and skills, and (4) attitudes toward medical genetics education. Descriptive statistics and a one-way analysis of variance were used for data analysis. Medical students in years 3, 4, and 5 (n = 473) from 25 medical schools participated in this research representing medical education in four Pakistani provinces. Most medical students reported "minimal" to "basic" knowledge of genetic testing methodology (64.7%), cancer genetics (64.9%), prenatal genetic testing (63.02%), and treatment strategies for genetic disease (72.9%). A plurality of students (37%) reported they were uncomfortable with interpreting and communicating genetic test results to patients. Medical students also expressed dissatisfaction with their medical genetics (40%) and genetic counselors training (42%). The self-perceived knowledge and clinical comfort with genetics among Pakistani medical students was limited, especially regarding genetic testing. A significant portion (74.5%) expressed desire for additional genetics education during medical school to aid in their role as future physicians. It is important for physicians-in-training to have a solid understanding of genetic concepts, technologies, and genetic counseling to best support their patients. As endorsed by the participating medical students, this study supports inclusion of more robust genetics' education into Pakistan's medical school curricula.

Knowledge, Attitude, and Practice About the Process of Genetic Counselling Among Clinicians

Introduction Clinicians agree with the fact that the impact of genetics in the field of medicine is humongous. They have to cope with the rapid advances in the field of clinical genetics and offer the best treatment to the patients at the right time. Disease with an underlying genetic cause not only involves the patient but also the family and the community. In the process of genetic counseling, the patient and the family are educated about the genetic basis of the disorder. This helps the patient and the family to make a well-informed decision. It also helps to reduce the genetic burden of the disease in the community over a period of time. In this regard, knowledge, attitude, and practice about the process of genetic counseling among clinicians is imperative. Methods A structured pre-validated questionnaire was distributed amongst 60 clinicians from different departments. Their responses were assessed based on the Likert scale. The data obtained were analyzed using descriptive statistics and expressed in percentages.  Results In the present study, nearly 90% of the clinicians felt that it was important to gather a multi-generational family history of the patient and advise them about inheritance patterns, recurrence risk, and genetic tests for a disorder with an underlying genetic cause. The need to educate the family members regarding the importance of genetic tests and referral to appropriate support groups if they test positive for a genetic disorder receive a positive response. Mostly the participants agreed that parents of children and couples at risk of having a child affected by a genetic disease should undergo genetic counseling. Conclusion Clinicians may not always be aware of the underlying genetic cause and genetic tests available or may face a paucity of time to counsel the patient and the family. Genetic counseling needs to be done at length in multiple sessions, and it is essential to reduce the burden of genetic disorders in society.

Stakeholder knowledge and attitudes toward the use of predictive genetic testing in South Africa

The use of predictive genetic testing, particularly for risk profiling in non-communicable diseases (NCDs), has the potential to benefit public health by decreasing the disease burden and alleviating the pressure on healthcare. It is thus important to assess knowledge and uptake among stakeholders. This study aimed to assess end users' (community, medical practitioners and medical students) knowledge and attitudes regarding the use and support of genomic medicine. A descriptive cross-sectional survey was conducted in Kwazulu-Natal (KZN) among 3 groups of stakeholders (n = 170): medical practitioners from both private and public healthcare, medical students from UKZN and community members represented by teachers. Three structured questionnaires using a Likert scale were administered. Responses were stratified by practice type, and a scoring scale was developed. Principal component analysis (PCA) was used to reduce data on all constructs that made up each variable. All three groups showed adequate knowledge and a positive attitude towards use, apart from medical students who were not as keen to support future use in their own practice. Although medical practitioners supported the use of this technology, with necessary guidelines, expertise and affordability, only 18% from private practice reported having used it. PCA reduced data to fewer parsimonious constructs for all 3 groups: common threads included an awareness that genetic testing may improve health and disease outcomes; guidelines for use; and the provision of education to increase awareness, training to bolster expertise and confidence to use these services. Participants in this study attributed a lack of uptake to limited expertise and professional support, and a lack of legislative guidelines. We recommend updating continuing professional development for medical practitioners and promoting community education concomitantly. Provision of guidelines and increased accessibility to resources are important.

Five Priorities of African Genomics Research: The Next Frontier

To embrace the prospects of accurately diagnosing thousands of monogenic conditions, predicting disease risks for complex traits or diseases, tailoring treatment to individuals' pharmacogenetic profiles, and potentially curing some diseases, research into African genomic variation is a scientific imperative. African genomes harbor millions of uncaptured variants accumulated over 300,000 years of modern humans' evolutionary history, with successive waves of admixture, migration, and natural selection combining with extensive ecological diversity to create a broad and exceptional genomic complexity. Harnessing African genomic complexity, therefore, will require sustained commitment and equitable collaboration from the scientific community and funding agencies. African governments must support academic public research and industrial partnerships that build the necessary genetic medicine workforce, utilize the emerging genomic big data to develop expertise in computer science and bioinformatics, and evolve national and global governance frameworks that recognize the ethical implications of data-driven genomic research and empower its application in African social, cultural, economic, and religious contexts. Expected final online publication date for the Annual Review of Genomics and Human Genetics, Volume 23 is October 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Assessing Medical Students' Knowledge of Genetics: Basis for Improving Genetics Curriculum for Future Clinical Practice

PURPOSE

The knowledge of genetics among medical students was assessed to identify and analyze gaps that serve as bases for the revision of the current genetics curriculum of the (Bachelor of Medicine, Bachelor of Surgery) MBBS Program of the College of Medicine at Princess Nourah bint Abdulrahman University (PNU).

METHODS

A 65-item multiple-choice (MCQs) test in Genetics was administered to 71 second and fourth-year medical students to assess their knowledge in Genetics. MCQs were validated and tested for their reliability. Self-assessment of students' genetics knowledge was also determined by asking them whether their knowledge in genetics is sufficient or not sufficient for their future clinical practice. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) version 20.

RESULTS

Forty-one second-year and thirty fourth-year medical students took the Genetic test. Exam results showed insufficient knowledge of Genetics, with 43.85% among the students answering the exam correctly. In self-assessment, the majority (83.3% to 87.8%) of the respondents considered their knowledge of genetics insufficient for future clinical practice. A higher knowledge level of basic genetics compared with clinically related genetics concepts was observed. Generally, second-year students significantly scored higher in molecular and cytogenetics (P=0.012), principles of genetic transmission (P=0.022), and inheritance of genetic diseases (P=0.024), compared with the fourth-year medical students who only scored higher in items related to cancer genetics (P=0.022).

CONCLUSION

Medical students' genetics knowledge is insufficient, especially on clinically oriented concepts like genetic testing and genetic counseling and should be strengthened for future clinical practice. The fourth-year medical students do not retain the knowledge of genetics; thus, integrating medical genetics in clinical years is imperative.

Genomics governance: advancing justice, fairness and equity through the lens of the African communitarian ethic of Ubuntu

There is growing interest for a communitarian approach to the governance of genomics, and for such governance to be grounded in principles of justice, equity and solidarity. However, there is a near absence of conceptual studies on how communitarian-based principles, or values, may inform, support or guide the governance of genomics research. Given that solidarity is a key principle in Ubuntu, an African communitarian ethic and theory of justice, there is emerging interest about the extent to which Ubuntu could offer guidance for the governance of genomics research in Africa. To this effect, we undertook a conceptual analysis of Ubuntu with the goal of identifying principles that could inform equity-oriented governance of genomics research. Solidarity, reciprocity, open sharing, accountability, mutual trust, deliberative decision-making and inclusivity were identified as core principles that speak directly to the different macro-level ethical issues in genomics research in Africa such as: the exploitation of study populations and African researchers, equitable access and use of genomics data, benefit sharing, the possibility of genomics to widen global health inequities and the fair distribution of resources such as intellectual property and patents. We use the identified the principles to develop ethical guidance for genomics governance in Africa.

Has translational genomics come of age in Africa?

The rapid increase in genomics research in Africa and the growing promise of precision public health begs the question of whether African genomics has come of age and is being translated into improved healthcare for Africans. An assessment of the continent's readiness suggests that genetic service delivery remains limited and extremely fragile. The paucity of data on mutation profiles for monogenic disorders and lack of large genome-wide association cohorts for complex traits in African populations is a significant barrier, coupled with extreme genetic variation across different regions and ethnic groups. Data from many different populations is essential to developing appropriate genetic services. Of the proposed genetic service delivery models currently used in Africa-Uncharacterized, Limited, Disease-focused, Emerging and Established-the first three best describe the situation in most African countries. Implementation is fraught with difficulties related to the scarcity of an appropriately skilled medical genetic workforce, limited infrastructure and processes, insufficient health funding and lack of political support, and overstretched health systems. There is a strong nucleus of determined and optimistic clinicians and scientists with a clear vision, and there is hope for innovative solutions and technological leapfrogging. However, a multi-dimensional approach with active interventions to stimulate genomic research, clinical genetics and overarching healthcare systems is needed to reduce genetic service inequalities and accelerate precision public health on the continent. Human and infrastructure capacity development, dedicated funding, political will and supporting legislation, and public education and awareness, are critical elements for success. Africa-relevant genomic and related health economics research remains imperative with an overarching need to translate knowledge into improved healthcare. Given the limited data and genetic services across most of Africa, the continent has not yet come of 'genomics' age.

Explanatory models for the cause of Fragile X Syndrome in rural Cameroon

Among the myriad causes of intellectual disability (ID), Fragile X Syndrome (FXS) is the leading genetic cause. Yet, little is known of how people affected by this condition make sense of it. The present study aimed to investigate the explanatory models for the causes of FXS in an extended family mainly affected by this condition and members of the village from which they originated in Cameroon. Using an ethnographic approach, 92 participants were interviewed (59 females and 33 males) through 10 focus group discussions and 23 in‐depth interviews between April 2018 and February 2020. Data analysis revealed four explanatory models regarding the etiologies of FXS in the community. Firstly, the curse model described a curse from the chief because of the belief that his wives did not mourn his intellectually disabled servant. Secondly, the spiritual model relates FXS to a punishment from God. Thirdly, the socioeconomic model attributes FXS to events in the prenatal and perinatal periods. Finally, the genetic model describes the pattern of inheritance of the disease in the family. This paper helps to understand the explanatory disease models that exist for FXS in rural Cameroon and could inform genetic counseling practices, community genetic education, and policymakers when drafting protocols for public engagement activities.

Challenges to effective and autonomous genetic testing and counseling for ethno-cultural minorities: a qualitative study

Background

The Arab population in Israel is a minority ethnic group with its own distinct cultural subgroups. Minority populations are known to underutilize genetic tests and counseling services, thereby undermining the effectiveness of these services among such populations. However, the general and culture-specific reasons for this underutilization are not well defined. Moreover, Arab populations and their key cultural-religious subsets (Muslims, Christians, and Druze) do not reside exclusively in Israel, but are rather found as a minority group in many European and North American countries. Therefore, focusing on the Arab population in Israel allows for the examination of attitudes regarding genetic testing and counseling among this globally important ethnic minority population.

Methods

We used a qualitative research method, employing individual interviews with 18 women of childbearing age from three religious subgroups (i.e., Druze, Muslim, and Christian) who reside in the Acre district, along with focus group discussions with healthcare providers (HCPs; 9 nurses and 7 genetic counselors) working in the same geographical district.

Results

A general lack of knowledge regarding the goals and practice of genetic counseling resulting in negative preconceptions of genetic testing was identified amongst all counselees. Counselors’ objective of respecting patient autonomy in decision-making, together with counselees’ misunderstanding of genetic risk data, caused uncertainty, frustration, and distrust. In addition, certain interesting variations were found between the different religious subgroups regarding their attitudes to genetic counseling.

Conclusions

The study highlights the miscommunications between HCPs, particularly counselors from the majority ethno-cultural group, and counselees from a minority ethno-cultural group. The need for nuanced understanding of the complex perspectives of minority ethno-cultural groups is also emphasized. Such an understanding may enhance the effectiveness of genetic testing and counseling among the Arab minority group while also genuinely empowering the personal autonomy of counselees from this minority group in Israel and other countries.

Cascade Testing for Fragile X Syndrome in a Rural Setting in Cameroon (Sub-Saharan Africa)

Fragile X Syndrome (FXS), an X-linked dominant monogenic condition, is the main genetic cause of intellectual disability (ID) and autism spectrum disorder (ASD). FXS is associated with an expansion of CGG repeat sequence in the Fragile X Mental Retardation gene 1 (FMR1) on chromosome X. Following a neuropediatric assessment of two male siblings who presented with signs of FXS that was confirmed with molecular testing, we provided cascade counselling and testing to the extended family. A total of 46 individuals were tested for FXS; among them, 58.70% (n = 27) were females. The mean age was 9.4 (±5) years for children and 45.9 (±15.9) years for adults. Pedigree analysis suggested that the founder of these families was likely a normal transmitting male. Four out of 19 males with clinical ID were confirmed to have a full mutation for FXS, while 14/27 females had a pathologic CGG expansion (>56 CGG repeats) on one of their X chromosomes. Two women with premature menopause were confirmed of being carriers of premutation (91 and 101 CGG repeats). We also identified maternal alleles (91 and 126 CGG repeats) which expanded to a full mutation in their offspring (>200 CGG repeats). This study is a rare report on FXS from Africa and illustrates the case scenario of implementing genetic medicine for a neurogenetic condition in a rural setting.

Returning incidental findings in African genomics research

Ancestral and geographical issues underlie the need to develop Africa-specific guidelines for the return of genomic research results in Africa. In this Commentary, we outline the challenges that will inform policies and practices moving forward.

The African Genomic Medicine Training Initiative (AGMT): Showcasing a Community and Framework Driven Genomic Medicine Training for Nurses in Africa

The potential of genomic medicine in improving the quality of healthcare both at population and individual-level is well-recognized globally. However, successful adoption of genetic and genomic evidence into clinical practice depends on training the healthcare workforce and clinical researchers in genomic medicine. Due to limited expertise in the medical genetics and genomics field, widespread uptake largely depends on task-shifting for the implementation of genomic medicine implementation to key healthcare professionals such as nurses. Their knowledge would be developed through courses aimed at professional development. Globally, trainers, and training initiatives in genomic medicine are in early stages of development, but resource limited settings such as the African continent face additional logistical and institutional challenges. The African Genomic Medicine Training (AGMT) Initiative was conceived during a combined conference of the African Society of Human Genetics (AfSHG) and the Human Heredity and Health in Africa Consortium (H3Africa) in 2016, Senegal, in response to the needs for developing knowledge and skills in genomic medicine. AGMT was established to implement a sustainable genomic medicine training initiative primarily for healthcare professionals who are not geneticists but are nurses, doctors, and pharmacists in Africa. This paper reports on the establishment of the AGMT initiative and the strategies developed and piloted by this initiative in designing and implementing an accredited frame-work and community-based blended learning course for nurses across 11 African countries. The global implementation experiences, outcomes and lessons learnt are highlighted. The AGMT initiative strategy takes advantage of existing research consortia and networks to train and create a pool of trainers and has adopted evidence-based approaches to guide curriculum and content development/adaptation. This initiative established the first Africa-wide online blended learning genomic medicine course which forms the basis from which to develop courses for other healthcare professionals and the wider public.

Reprogenetics, reproductive risks and cultural awareness: what may we learn from Israeli and Croatian medical students?

Background

Past studies emphasized the possible cultural influence on attitudes regarding reprogenetics and reproductive risks among medical students who are taken to be “future physicians.” These studies were crafted in order to enhance the knowledge and expand the boundaries of cultural competence. Yet such studies were focused on MS from relatively marginalized cultures, namely either from non-Western developing countries or minority groups in developed countries. The current study sheds light on possible cultural influences of the dominant culture on medical students in two developed countries, potentially with different dominant cultures regarding reprogenetics and reproductive risks: Israel and Croatia.

Methods

Quantitative-statistical analyses were employed, based on anonymous questionnaires completed by 150 first year medical students in Israel and Croatia. The questionnaires pertained to the knowledge and attitudes regarding genetics, reproduction and reproductive risks. These questionnaires were completed before the students were engaged in learning about these topics as part of the curriculum in their medical school.

Results

Substantial differences were revealed between the two groups of medical students. Israeli medical students were less tolerant regarding reproductive risks and more knowledgeable about genetics and reproductive risks than Croatian medical students. For example, while nearly all Israeli medical students (96%) disagreed with the idea that “Screening for reproductive risks in prospective parents is wrong,” less than 40% of their Croatian counterparts shared a similar stance. Similarly, all (100%) Israeli medical students correctly observed that “A carrier of a recessive genetic disease actually has the disease” was wrong, as opposed to only 82% of Croatian students.

Conclusions

By linking applicable theoretical literature to these findings, we suggest that they may reflect the hidden influence of the dominant culture in each country, disguised as part of the “culture of medicine.” Acknowledging and learning about such influence of the dominant culture, may be an important addition to the training of medical students in cultural competence, and specifically their cultural awareness. Such an acknowledgement may also pave the road to drawing the attention of existing physicians regarding a less known yet an important aspect of their cultural competence, insofar as the cultural awareness component is concerned.

Attitude of Jordanian Physicians toward Biochemistry and Genetics

Background. Several studies found that physicians develop a negative attitude toward biochemistry and genetics disciplines. Many medical schools adopt an integrated system-based curriculum supplemented with clinical correlations. Medical schools in Jordan switched to the integrated curriculum; however, studies that evaluate the attitude of physicians toward biochemistry and genetics are lacking. Objectives. This study aimed to evaluate the attitude of physicians toward biochemistry and genetics including the correlation of their curricula with clinical practice. Materials and Methods. A structured questionnaire consisting of 40 statements was distributed to a random sample of 616 physicians practicing in private and governmental hospitals in Jordan. Participants earned their MD or MBBS degree from Jordan or other countries and were interns, residents, or specialists. Results. More than half of the participants admitted that biochemistry and genetics are intellectually challenging and were among their least favourite subjects (59.1%); however, many of them were familiar with some of the contemporary advances in biochemistry and genetics and their translational potential (64.0%). Most of the participants felt that modifying the medical school curriculum by integrating biochemical and genetic concepts with clinical teaching will motivate the medical students (74%). In univariate analysis, residents showed the most positive attitudes and were the most knowledgeable about the biochemical changes associated with diseases and about the contemporary advances in biochemistry or genetics (P<0.05). In multivariate analysis, physicians practicing in the private sector or those with more than five years of experience generally had a more positive attitude toward biochemistry and genetics (P<0.05). Conclusion. Physicians in Jordan showed an overall positive attitude toward biochemistry and genetics. This was more evident among residents, physicians with more than five years of experience, or those practicing in the private sector.

Role of genomics literacy in reducing the burden of common genetic diseases in Africa

BACKGROUND

In Africa, health practitioners and the current knowledge of the public on genetics and genomics is still very low and yet this has potential to reduce the burden of common genetic diseases. Many initiatives have promoted genomic research, infrastructure, and capacity building in Africa. What remains to be done is to improve genomics literacy among populations and communities while utilizing an array of strategies. Genomic literacy and awareness are key in the management of genetic diseases which includes diagnosis, prevention of complications and therapy. Africa is characterized by great cultural and language diversity thereby requiring a multidisciplinary approach to improving public and community genomics literacy and engagement. However, this is further complicated by having the fact that sub-Saharan Africa is comprised of countries with the lowest literacy rates in the world.

METHODS

We applied the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to review genomic literacy in Africa using PubMed database.

RESULTS

We found very limited evidence of genomics literacy for genetic diseases in Africa.

CONCLUSION

We propose a number of approaches that if adopted will significantly increase the genomic literacy and reduce the burden of genetic diseases in Africa.

Ethical, social, and cultural issues related to clinical genetic testing and counseling in low- and middle-income countries: a systematic review

PURPOSE

We performed a systematic review of the ethical, social, and cultural issues associated with delivery of genetic services in low- and middle-income countries (LMICs).

METHODS

We searched 11 databases for studies addressing ethical, social, and/or cultural issues associated with clinical genetic testing and/or counselling performed in LMICs. Narrative synthesis was employed to analyze findings, and resultant themes were mapped onto the social ecological model (PROSPERO #CRD42016042894).

RESULTS

After reviewing 13,308 articles, 192 met inclusion criteria. Nine themes emerged: (1) genetic counseling has a tendency of being directive, (2) genetic services have psychosocial consequences that require improved support, (3) medical genetics training is inadequate, (4) genetic services are difficult to access, (5) social determinants affect uptake and understanding of genetic services, (6) social stigma is often associated with genetic disease, (7) family values are at risk of disruption by genetic services, (8) religious principles pose barriers to acceptability and utilization of genetic services, and (9) cultural beliefs and practices influence uptake of information and understanding of genetic disease.

CONCLUSION

We identified a number of complex and interrelated ethical, cultural, and social issues with implications implications for further development of genetic services in LMICs.

Genomic Medicine Without Borders: Which Strategies Should Developing Countries Employ to Invest in Precision Medicine? A New "Fast-Second Winner" Strategy

Genomic medicine has greatly matured in terms of its technical capabilities, but the diffusion of genomic innovations worldwide faces significant barriers beyond mere access to technology. New global development strategies are sorely needed for biotechnologies such as genomics and their applications toward precision medicine without borders. Moreover, diffusion of genomic medicine globally cannot adhere to a "one-size-fits-all-countries" development strategy, in the same way that drug treatments should be customized. This begs a timely, difficult but crucial question: How should developing countries, and the resource-limited regions of developed countries, invest in genomic medicine? Although a full-scale investment in infrastructure from discovery to the translational implementation of genomic science is ideal, this may not always be feasible in all countries at all times. A simple "transplantation of genomics" from developed to developing countries is unlikely to be feasible. Nor should developing countries be seen as simple recipients and beneficiaries of genomic medicine developed elsewhere because important advances in genomic medicine have materialized in developing countries as well. There are several noteworthy examples of genomic medicine success stories involving resource-limited settings that are contextualized and described in this global genomic medicine innovation analysis. In addition, we outline here a new long-term development strategy for global genomic medicine in a way that recognizes the individual country's pressing public health priorities and disease burdens. We term this approach the "Fast-Second Winner" model of innovation that supports innovation commencing not only "upstream" of discovery science but also "mid-stream," building on emerging highly promising biomarker and diagnostic candidates from the global science discovery pipeline, based on the unique needs of each country. A mid-stream entry into innovation can enhance collective learning from other innovators' mistakes upstream in discovery science and boost the probability of success for translation and implementation when resources are limited. This à la carte model of global innovation and development strategy offers multiple entry points into the global genomics innovation ecosystem for developing countries, whether or not extensive and expensive discovery infrastructures are already in place. Ultimately, broadening our thinking beyond the linear model of innovation will help us to enable the vision and practice of genomics without borders in both developed and resource-limited settings.

Genomics research in Africa and its impact on global health: insights from African researchers

Africa may be heading for an era of genomics medicine. There are also expectations that genomics may play a role in reducing global health inequities. However, the near lack of genomics studies on African populations has led to concerns that genomics may widen, rather than close, the global health inequity gap. To prevent a possible genomics divide, the genomics 'revolution' has been extended to Africa. This is motivated, in part, by Africa's rich genetic diversity and high disease burden. What remains unclear, however, are the prospects of using genomics technology for healthcare in Africa. In this qualitative study, we explored the views of 17 genomics researchers in Africa on the prospects and challenges of genomics medicine in Africa. Interviewees were researchers in Africa who were involved in genomics research projects in Africa. Analysis of in-depth interviews suggest that genomics medicine may have an impact on disease surveillance, diagnosis, treatment and prevention. However, Africa's capacity for genomics medicine, current research priorities in genomics and the translation of research findings will be key defining factors impacting on the ability of genomics medicine to improve healthcare in Africa.

Hospital nursing leadership-led interventions increased genomic awareness and educational intent in Magnet settings

BACKGROUND

The Precision Medicine Initiative will accelerate genomic discoveries that improve health care, necessitating a genomic competent workforce.

PURPOSE

This study assessed leadership team (administrator/educator) year-long interventions to improve registered nurses' (RNs) capacity to integrate genomics into practice.

METHODS

We examined genomic competency outcomes in 8,150 RNs.

FINDINGS

Awareness and intention to learn more increased compared with controls. Findings suggest achieving genomic competency requires a longer intervention and support strategies such as infrastructure and policies. Leadership played a role in mobilizing staff, resources, and supporting infrastructure to sustain a large-scale competency effort on an institutional basis.

DISCUSSION

Results demonstrate genomic workforce competency can be attained with leadership support and sufficient time. Our study provides evidence of the critical role health-care leaders play in facilitating genomic integration into health care to improve patient outcomes. Genomics' impact on quality, safety, and cost indicate a leader-initiated national competency effort is achievable and warranted.

Ethical, social, and cultural issues related to clinical genetic testing and counseling in low- and middle-income countries: protocol for a systematic review

BACKGROUND

There has been little focus in the literature on how to build genetic testing and counseling services in low- and middle-income countries in a responsible, ethical, and culturally appropriate manner. It is unclear to what extent this area is being explored and what form further research should take. The proposed knowledge synthesis aims to fill this gap in knowledge and mine the existing data to determine the breadth of work in this area and identify ethical, social, and cultural issues that have emerged.

METHODS/DESIGN

An integrated knowledge translation approach will be undertaken by engaging knowledge users throughout the review to ensure relevance to their practice. Electronic databases encompassing various disciplines, such as healthcare, social sciences, and public health, will be searched. Studies that address clinical genetic testing and/or counseling and ethical, social, and/or cultural issues of these genetic services, and are performed in low- and middle-income countries as defined by World Bank will be considered for inclusion. Two independent reviewers will be involved in a two-stage literature screening process, data extraction, and quality appraisal. Studies included in the review will be analyzed by thematic analysis. A narrative synthesis guided by the social ecological model will be used to summarize findings.

DISCUSSION

This systematic review will provide a foundation of evidence regarding ethical, social, and cultural issues related to clinical genetic testing and counseling in low- and middle-income countries. Using the social ecological model as a conceptual framework will facilitate the understanding of broader influences of the sociocultural context on an individual's experience with clinical genetic testing and counseling, thereby informing interdisciplinary sectors in future recommendations for practice and policy.

The 22q11.2 Deletion Syndrome in Congenital Heart Defects: Prevalence of Microdeletion Syndrome in Cameroon

BACKGROUND

The 22q11.2 deletion syndrome is amongst the most common microdeletion syndrome in humans. Its prevalence remains unknown in sub-Saharan Africa, and its clinical features are under-reported for people of African descent.

OBJECTIVE

We have investigated the prevalence of the 22q11.2 deletion syndrome in patients with congenital heart defects in Cameroon.

METHODS

A total of 70 of 100 cases of congenital cardiac malformation with echocardiographic evidence were examined prospectively and tested for the 22q11.2 deletion, using multiplex ligation-dependent probe amplification and fluorescence in situ hybridization.

RESULTS

Two of 70 patients (2.8%) were found to have 22q11.2 deletion. Both cases had conotruncal heart defects and exhibited extracardiac features of the 22q11.2 deletion syndrome that were either classical (e.g., puffy upper eyelids, bulbous tip of the nose) or less identifiable (telecanthus, hooding of eyelids and prominent nasal bridge).

CONCLUSIONS

The report shows that the prevalence of the 22q11.2 deletion syndrome in patients with heart malformations in Cameroon (2.8%) is similar to that of various world populations. The clinical phenotypes will contribute to the Global Atlas for dysmorphology. "Omics" technologies offer much promise in genetic/genomic screening of severe global health problems.

Community Health Workers: An Untapped Resource to Promote Genomic Literacy

Poor understanding of gene-environment contributors to health conditions can lead the public to misinterpretations that overemphasize genetics as determinants of health. The present commentary calls for engaging the national community health worker (CHW) workforce to use community elicitation methods such as mental models approaches as a means to enhance the public's literacy regarding genetic and environmental or genomic contributions to health. We discuss three needs related to genomic literacy and suggest how CHWs are uniquely positioned to address these needs among diverse target audiences. We conclude by offering directions for the future of CHWs working to build genomic literacy.

Success stories in genomic medicine from resource-limited countries

In recent years, the translation of genomic discoveries into mainstream medical practice and public health has gained momentum, facilitated by the advent of new technologies. However, there are often major discrepancies in the pace of implementation of genomic medicine between developed and developing/resource-limited countries. The main reason does not only lie in the limitation of resources but also in the slow pace of adoption of the new findings and the poor understanding of the potential that this new discipline offers to rationalize medical diagnosis and treatment. Here, we present and critically discuss examples from the successful implementation of genomic medicine in resource-limited countries, focusing on pharmacogenomics, genome informatics, and public health genomics, emphasizing in the latter case genomic education, stakeholder analysis, and economics in pharmacogenomics. These examples can be considered as model cases and be readily replicated for the wide implementation of pharmacogenomics and genomic medicine in other resource-limited environments.

Perspectives in Genetics and Sickle Cell Disease Prevention in Africa: Beyond the Preliminary Data from Cameroon

Management of sickle cell disease (SCD) in Africa needs to be accompanied by various preventive strategies, including early detection via prenatal genetic diagnosis (PND). Contrary to Cameroonian doctors who considered termination of an affected pregnancy (TAP) for SCD in 36.1%, the majority of parents (62.5%) with affected children accepted TAP in principle. In practice, most women opted for TAP (90%), justified by a huge psycho-social burden. The ethical and legal challenges of PND prompted the need to explore the use of genetics for secondary prevention of SCD. In 610 Cameroonian SCD patients, the genomic variations in two principal foetal haemoglobin-promoting loci were significantly associated with foetal haemoglobin levels. In addition, the co-inheritance of a 3.7-kb α-globin gene deletion and SCD was associated with a late disease onset and possibly improved survival: there was a much higher allele frequency of the 3.7-kb α-globin gene deletion in SCD patients (∼ 40%) than in haemoglobin AA controls (∼ 10%). The data indicate the urgent need to develop and implement policy actions in sub-Saharan Africa on at least four levels: (1) the implementation of SCD screening practices and early neonatal follow-up; (2) the development and incorporating of socio-economic support to alleviate the burden of SCD on affected families; (3) the exploration of the appropriateness of the medical abortion laws for SCD, and (4) the development of national plans for genetic medicine, including research on genomic variants that affect the phenotypes of SCD, in order to potentially use them for anticipatory guidance.

Community engagement strategies for genomic studies in Africa: a review of the literature

BACKGROUND

Community engagement has been recognised as an important aspect of the ethical conduct of biomedical research, especially when research is focused on ethnically or culturally distinct populations. While this is a generally accepted tenet of biomedical research, it is unclear what components are necessary for effective community engagement, particularly in the context of genomic research in Africa.

METHODS

We conducted a review of the published literature to identify the community engagement strategies that can support the successful implementation of genomic studies in Africa. Our search strategy involved using online databases, Pubmed (National Library of Medicine), Medline and Google scholar. Search terms included a combination of the following: community engagement, community advisory boards, community consultation, community participation, effectiveness, genetic and genomic research, Africa, developing countries.

RESULTS

A total of 44 articles and 1 thesis were retrieved of which 38 met the selection criteria. Of these, 21 were primary studies on community engagement, while the rest were secondary reports on community engagement efforts in biomedical research studies. 34 related to biomedical research generally, while 4 were specific to genetic and genomic research in Africa.

CONCLUSION

We concluded that there were several community engagement strategies that could support genomic studies in Africa. While many of the strategies could support the early stages of a research project such as the recruitment of research participants, further research is needed to identify effective strategies to engage research participants and their communities beyond the participant recruitment stage. Research is also needed to address how the views of local communities should be incorporated into future uses of human biological samples. Finally, studies evaluating the impact of CE on genetic research are lacking. Systematic evaluation of CE strategies is essential to determine the most effective models of CE for genetic and genomic research conducted in African settings.

Medical students' attitudes towards people with intellectual disabilities: a literature review

The present paper provides a review of research on medical students' attitudes to people with intellectual disabilities. The attitudes of medical students warrant empirical attention because their future work may determine people with intellectual disabilities' access to healthcare and exposure to health inequalities. An electronic search of Embase, Ovid MEDLINE(R), PsycINFO, Scopus, and Web of Science was completed to identify papers published up to August 2013. Twenty-four studies were identified, most of which evaluated the effects of pedagogical interventions on students' attitudes. Results suggested that medical students' attitudes to people with intellectual disabilities were responsive to interventions. However, the evidence is restricted due to research limitations, including poor measurement, self-selection bias, and the absence of control groups when evaluating interventions. Thus, there is a dearth of high-quality research on this topic, and past findings should be interpreted with caution. Future research directions are provided.

How risky are second trimester clandestine abortions in Cameroon: a retrospective descriptive study

Background

Complications of clandestine abortions increase with gestational age. The aim of this study was to identify complications of second trimester clandestine abortions (STA) and those of first trimester clandestine abortions (FTA).

Methods

This retrospective descriptive study was conducted between March 1st and August 31st, 2012 in the University Teaching Hospital and the Central Hospital, Yaoundé (Cameroon). The files of women with clandestine abortions carried out outside our units, but received in our settings for some complications were reviewed. Variables studied were maternal age, parity, marital status, gestational age at the time of abortion, the abortion provider and the method used, the duration of antibiotic coverage, the time interval between abortion and consultation, the complications presented and the duration of hospital stay. Data of 20 women with STA (≥13 weeks 1 day) and those of 74 women with FTA (≤13 complete weeks) were analyzed and compared. The t-test was used to compare continuous variables. P value <0.05 was considered statistically significant.

Results

Women with STA had high parities (P = 0.0011). STAs were mostly performed by nurses and were usually done by dilatation and curettage or dilatation and evacuation, manual vacuum aspiration, intramuscular injection of an unspecified medication, transcervical foreign body insertion, amniotomy and misoprostol. STA complications were severe anemia, hypovolemic shock, uterine perforation and maternal death.

Conclusions

Clandestine abortions, especially second trimester abortions, are associated with risks of maternal morbidity and mortality especially when done by nurses. Therefore, women should seek for help directly from trained health personnel (Gynecologists & Obstetricians). Moreover, nurses should be trained in uterine evacuation procedures. They should also refer women who want to carry out STA to Gynecologists and Obstetricians. Finally, to reduce the prevalence of abortion in general, the government should make contraception available to all women, as well as use public media to sensitize women on the dangers of abortion and on the need to use family planning services.

Would you terminate a pregnancy affected by sickle cell disease? Analysis of views of patients in Cameroon

Sickle cell disease (SCD) is a debilitating illness that affects quality of life and life expectancy for patients. In Cameroon, it is now possible to opt for termination of an affected pregnancy (TAP) where the fetus is found to be affected by SCD. Our earlier studies found that, contrary to the views of Cameroonian physicians, a majority of parents with their children suffering from SCD would choose to abort if the fetuses were found to be affected. What have not yet been investigated are the views of people suffering from/living with SCD. We used a quantitative sociological method, with administered structured questionnaires, to study the attitudes of adult patients suffering from SCD on prenatal genetic diagnosis (PND) and possible TAP. The majority of the 89 participants were urban dwellers (84.3%), women (57.3%), Christian (95.5%) and single (90.9%), with a secondary/tertiary education (79.5%). The majority (89.2%) would consider PND for SCD; almost half (48.5%) would reject TAP while 40.9% would consider it. Respondents who rejected TAP claimed mostly ethical reasons (78.1%) while those who found TAP acceptable cited fear of having an affected child (88.9%) and the poor quality of the affected child's health (81.5%). Cameroonian patients with SCD are generally supportive of PND and a remarkably high number of patients living with SCD reported that they would consider terminating a pregnancy based on their assessment of the future well-being of the child. Research is required to investigate the burden of SCD on families and their quality of life.

Developing clinical cancer genetics services in resource-limited countries: the case of retinoblastoma in Kenya

BACKGROUND/AIMS

Clinical cancer genetics is an integral part of cancer control and management, yet its development as an essential medical service has been hindered in many low-and-middle-income countries. We report our experiences in developing a clinical cancer genetics service for retinoblastoma in Kenya.

METHODS

A genetics task force was created from within the membership of the existing Kenyan National Retinoblastoma Strategy group. The task force engaged in multiple in-person and telephone discussions, delineating experiences, opinions and suggestions for an evidence-based, culturally sensitive retinoblastoma genetics service. Discussions were recorded and thematically categorized to develop a strategy for the design and implementation of a national retinoblastoma clinical genetics service.

RESULTS

Discussion among the retinoblastoma genetics task force supported the development of a comprehensive genetics service that rests on 3 pillars: (1) patient and family counseling, (2) community involvement, and (3) medical education.

CONCLUSIONS

A coordinated national retinoblastoma genetics task force led to the creation of a unique and relevant approach to delivering comprehensive and accurate genetic care to Kenyan retinoblastoma patients. The task force aims to stimulate innovative approaches in cancer genetics research, education and knowledge translation, taking advantage of unique opportunities offered in the African context.

A call for policy action in sub-Saharan Africa to rethink diagnostics for pregnancy affected by sickle cell disease: differential views of medical doctors, parents and adult patients predict value conflicts in Cameroon

Sickle cell disease (SCD) is a debilitating illness that affects the life expectancy of patients. It is possible to test for SCD before birth, to allow for reproductive options to parents. However, under Cameroonian Law, voluntary abortion is a criminal offense and medical abortion is permitted only "…if it is done by an authorized professional and justified by the need to save the mother from grave health jeopardy." The objective of the present study was to compare the views of Cameroonian doctors, parents with at least one living SCD-affected child, and adult SCD patients, regarding prenatal genetic diagnosis and termination of SCD-affected pregnancy. We conducted a quantitative sociological survey of 110 doctors, 130 parents, and 89 adult patients. The majority accepted the prenatal genetic diagnosis for SCD (78.7%, 89.8%, and 89.2%, respectively). Parents (62.5%) were more in favor of termination of SCD-affected pregnancy, than doctors and adults patients (36.1% and 40.9% acceptance, respectively). Parents and patients who found medical abortion acceptable cited fear to have a SCD-affected child (98.1 and 88.9%) and the poor quality of the affected child's health (92.6% and 81.5%). The data underscore the urgency of policy action to place emphasis on: premarital screening, early detection and care of SCD, socio-economic measures to assist SCD-affected families, appropriateness to consider maternal distress due to fetal anomalies in medical abortion legislation. These novel findings signal potential value-based conflicts on the horizon, and can usefully inform the future policy actions in the African continent as OMICS biotechnologies are increasingly employed in global health. To the best of our knowledge, the present study is the first attempt in sub-Saharan Africa to attempt to triangulate the views of multiple stakeholders towards prenatal diagnosis of SCD and termination of an affected pregnancy.

Cytochrome P450 pharmacogenetics in African populations: implications for public health

INTRODUCTION

Africa harbors a disproportionate burden of disease when taking into account the triple challenge caused by HIV/AIDS, tuberculosis (TB) and malaria, against a backdrop of an increasing burden of noncommunicable diseases. More than 80% of therapeutic drugs used in the management of these diseases/conditions are metabolized by CYP enzymes that exhibit genetic polymorphisms.

AREAS COVERED

There is variability in the expression and activities of CYPs resulting in interindividual differences in the response to standard doses of therapeutic drugs, due to genetic polymorphisms, which exhibit both quantitative and qualitative differences between racial and between ethnic groups. The review aims to evaluate the implications of the genetic variation in CYPs on the public health of Africans. The CYPs reviewed here metabolize most of the commonly used therapeutic drugs and include CYP1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 3A4 and 3A5. Allele frequencies are compared between African ethnic groups and among populations of African, Asian and European origin. Data are obtained from our own studies and literature.

EXPERT OPINION

The variability in the pattern of genetic variation between populations translates into differences in drug response. Understanding CYP variability improves rational drug use and has public health significance.

Sickle cell disease: new opportunities and challenges in Africa

Sickle cell disease (SCD) is one of the most common genetic causes of illness and death in the world. This is a review of SCD in Africa, which bears the highest burden of disease. The first section provides an introduction to the molecular basis of SCD and the pathophysiological mechanism of selected clinical events. The second section discusses the epidemiology of the disease (prevalence, morbidity, and mortality), at global level and within Africa. The third section discusses the laboratory diagnosis and management of SCD, emphasizing strategies that been have proven to be effective in areas with limited resources. Throughout the review, specific activities that require evidence to guide healthcare in Africa, as well as strategic areas for further research, will be highlighted.

Local concepts of anemia-related illnesses and public health implications in the Taabo health demographic surveillance system, Côte d'Ivoire

BACKGROUND

A 14-month prospective longitudinal study conducted in the Taabo health demographic surveillance system (HDSS), south-central Côte d'Ivoire, revealed high prevalence of anemia in different population groups in three types of settings (i.e., small town, village, and hamlet). Demographic parameters and several variables related to parasitic infections, micronutrient status, and inflammation were significantly associated with higher odds of anemia. However, cultural concepts and knowledge of various anemia-related illnesses and their relation with people's behaviors have not been investigated.

METHODS

Sixteen focus group discussions and six key informant interviews were performed with village authorities, health workers, and traditional healers. Questionnaires were administrated to 200 school-aged children and 115 young women. Of these individuals, 206 participated in the preceding longitudinal study, whereas the remaining 109 people were not exposed to prior research, but had similar age and sex profiles. Mean prominence of participants' responses was compared between groups of participants and across study settings.

RESULTS

Local concepts of anemia-related illnesses referred to its perceived causes based on two logical frameworks - biomedical and sociocultural - although a clear distinction was often blurred. We found few differences in knowledge, beliefs, and behaviors across study settings and between participants who were exposed to prior research and newly recruited ones. Malaria und nutritional issues as understood and managed by the population differed from definitions and recommendations provided by the health system. Malaria was not acknowledged as an exclusive mosquito-transmitted disease and participants referred to the quantity, rather than the quality, of food when talking about nutritional issues.

CONCLUSIONS

Local concepts and ideas about anemia have public health implications, inasmuch as they are related to people's attitudes, risk-related and help-seeking behaviors, which in turn might affect their health status. Local terminology and beliefs about anemia and malaria should be carefully considered when developing health intervention and education programs. The similarity in knowledge about anemia-related illnesses and associated behaviors, regardless of study setting and prior exposure to research, suggests that a uniform communication strategy may be used to develop education programs and awareness campaigns aimed at the prevention and control of anemia in south-central Côte d'Ivoire.

Acceptability of prenatal diagnosis by a sample of parents of sickle cell anemia patients in Cameroon (sub-Saharan Africa)

Little is known about attitudes of parents of Sickle Cell Anemia patients in sub-Saharan Africa regarding prenatal genetic diagnosis and termination of an affected pregnancy. In this study, structured face-to-face interviews were conducted with a sample of 130 parents in Cameroon that had at least one living child with Sickle Cell Anemia. The majority of participants lived in urban areas (89%), were female (80%), Christian (93%), married (60.2%) in monogamous households (81.1%), were employed (61.7%), and had at least a secondary or tertiary education (82%). The majority of parents accepted the principle of prenatal genetic diagnosis for Sickle Cell Anemia (89.8%) and termination of pregnancy (62.5%). Acceptance of the principle of pregnancy termination increased with unemployment (p<.01) and single marital status (p<.05). The results of this study suggest Cameroonian parents with children affected with Sickle Cell Anemia generally accept the principles of prenatal diagnosis and in some cases termination of a pregnancy affected with Sickle Cell Anemia. Additional findings, policy and practice implications, and research recommendations are presented.

Initiation of a medical genetics service in sub-Saharan Africa: experience of prenatal diagnosis in Cameroon

BACKGROUND

Initiation of Prenatal Genetic Diagnosis (PND) has laid the foundation of the first medical genetic service in Cameroon.

METHOD

Cross-sectional descriptive study, illustrating some aspects of the genetic service using a small 24-months PND experience.

RESULTS

The service began with a medical geneticist who had to follow-up the building and equipments supplies of the diagnosis laboratory; and to personally perform genetic consultations, molecular experiments and post-results counseling. PND was indicated for sickle cell disease (SCD) in 33 cases (55%) and chromosomal anomalies in 27 cases (45%). With international collaboration, DNA analysis revealed 6 SCD-affected foetuses (20.7%); QF-PCR (N=25) and full karyotype (N=8) analysis revealed cases of trisomy 21 and trisomy 18. Following PND success, national effort granted more human and material resources to improve the service. The preliminary experience was made possible by three factors: 1) the availability of a trained Cameroonian medical geneticist 2) the availability of obstetricians trained in fetal medicine and 3) advocacy initiatives at national and international levels, which have proven invaluable for advice, training, sourcing of materials, and back-up reference diagnostic laboratory.

CONCLUSION

The practice of medical genetics, involving prenatal genetic diagnosis of sickle cell disease and chromosomal anomalies, is possible in Cameroon (sub-Saharan Africa).

Women's experiences of the abortion law in Cameroon: "What really matters"

While prosecutions of women who have had an illegal abortion are rare in Cameroon, women who have a legitimate claim to a legal abortion, e.g. following rape, can rarely take advantage of it. This is because the law in Cameroon is not applied, either when it is violated or when it is indicated. This paper examines the histories of four young women who became pregnant and had an abortion in the Anglophone region of the Cameroon Grassfields. Three of them became pregnant following rape or sexual coercion, in one case by the girl's priest, in the second case by her employer's son, and in the third case by a stranger. The fourth young woman, who sold sex for survival money and food, had two abortions while in prison for committing infanticide following a failed attempt to abort an earlier pregnancy. The four young women were interviewed as part of a qualitative, hospital-based study among 65 women who had had abortions in 1996-97. The women's affecting personal histories illuminate the reality of living under a restrictive abortion law, the troubling conditions in which they have to manage their lives, and the harsh circumstances in which they become pregnant and seek (but may not find) a safe abortion.

Public health genomics knowledge and attitudes: a survey of public health educators in the United States

PURPOSE

This study assessed U.S. public health educators' attitudes toward genomic competencies, their awareness of efforts in the health promotion field to promote/incorporate genomics, and their basic & applied genomic knowledge.

METHODS

A total of 1607 public health educators, nationwide, responded to a web-based survey.

RESULTS

The sample comprised predominantly white (76.8%) female (83.9%) participants, with an average age of 40.1 years and 11.2 years of practice in public health education/promotion. Generally, participants had negative attitudes toward genomic competencies, low awareness, and deficient genomic knowledge. Although various socioeconomic characteristics (e.g., ethnicity, gender, and educational level) correlated with participants' attitudes, awareness, and genomic knowledge, training in genetics/genomics or public health genomics also exhibited a positive association. After we controlled for socioeconomic factors, awareness, training, and genomic knowledge remained significantly associated with respondents' attitudes toward genomic competencies.

CONCLUSION

Although this sample of public health educators had unfavorable attitudes and limited genomic knowledge, training seems to affect these variables. Thus, relevant training for this group of health professionals should be developed and advocated. Continuing education tools, focusing on public health genomics content, might be a venue for delivery of information and the development of favorable professional attitudes.
