RESUMO

African-ancestry (AA) participants are underrepresented in genetics research. Here, we conducted a transcriptome-wide association study (TWAS) in AA female participants to identify putative breast cancer susceptibility genes. We built genetic models to predict levels of gene expression, exon junction, and 3' UTR alternative polyadenylation using genomic and transcriptomic data generated in normal breast tissues from 150 AA participants and then used these models to perform association analyses using genomic data from 18,034 cases and 22,104 controls. At Bonferroni-corrected P < 0.05, we identified six genes associated with breast cancer risk, including four genes not previously reported (CTD-3080P12.3, EN1, LINC01956 and NUP210L). Most of these genes showed a stronger association with risk of estrogen-receptor (ER) negative or triple-negative than ER-positive breast cancer. We also replicated the associations with 29 genes reported in previous TWAS at P < 0.05 (one-sided), providing further support for an association of these genes with breast cancer risk. Our study sheds new light on the genetic basis of breast cancer and highlights the value of conducting research in AA populations.

RESUMO

We performed genome-wide association studies of breast cancer including 18,034 cases and 22,104 controls of African ancestry. Genetic variants at 12 loci were associated with breast cancer risk (P < 5 × 10-8), including associations of a low-frequency missense variant rs61751053 in ARHGEF38 with overall breast cancer (odds ratio (OR) = 1.48) and a common variant rs76664032 at chromosome 2q14.2 with triple-negative breast cancer (TNBC) (OR = 1.30). Approximately 15.4% of cases with TNBC carried six risk alleles in three genome-wide association study-identified TNBC risk variants, with an OR of 4.21 (95% confidence interval = 2.66-7.03) compared with those carrying fewer than two risk alleles. A polygenic risk score (PRS) showed an area under the receiver operating characteristic curve of 0.60 for the prediction of breast cancer risk, which outperformed PRS derived using data from females of European ancestry. Our study markedly increases the population diversity in genetic studies for breast cancer and demonstrates the utility of PRS for risk prediction in females of African ancestry.

RESUMO

BACKGROUND: In order to select nursing actions that will produce the desired results, a nursing diagnosis is crucial. Despite this, it can be challenging for nursing students to recognize and create precise nursing diagnostic labels that are particular to a patient's situation. The study's objectives are to identify the diagnostic labels, classes, and domains that are frequently formulated by nursing students. MATERIALS AND METHODS: A descriptive cross-sectional methodology and a self-developed questionnaire were utilized to gather information from 120 nursing students who were chosen using a simple random sampling technique. Descriptive and inferential (Chi-square) statistics were used to analyze the data. The 0.05 P- value was chosen. RESULTS: The respondent's average age is 23 ± 21.4 years. The majority of respondents (94.2%) concurred that greater exposure to clinical settings, case discussion methods (92.5%), as well as group case studies (90.8%) strategy, can all improve the creation of precise diagnostic labels. Additionally, the deficient fluid volume diagnostic label is the one that is most usually utilized (78.3%). Overall results show that the diagnostic labels that are used the most frequently are those for domains 4 (Activity/Rest) and 11 (Safety/Protection). There was no relationship (P = 0.061) between the commonly used diagnostic label and the chosen schools. CONCLUSION: The study offered empirical data on the most used diagnostic labels and domains. Therefore, it will be important that nursing students involve critical reasoning skills as well as familiarize themselves with other significant domains and classes that are useful in the patient's care.

RESUMO

PURPOSE: To examine the association between benign breast disease (BBD) and breast cancer (BC) in a heterogeneous population of African women. METHODS: BC cases and controls were enrolled in three sub-Saharan African countries, Nigeria, Cameroon, and Uganda, between 1998 and 2018. Multivariable logistic regression was used to test the association between BBD and BC. Risk factors dually associated with BBD and BC were selected. Using a parametric mediation analysis model, we assessed if selected BC risk factors were mediated by BBD. RESULTS: Of 6,274 participants, 55.6% (3,478) were breast cancer cases. 360 (5.7%) self-reported BBD. Fibroadenoma (46.8%) was the most commonly reported BBD. Women with a self-reported history of BBD had greater odds of developing BC than those without (adjusted odds ratio [aOR] 1.47, 95% CI 1.13-1.91). Biopsy-confirmed BBD was associated with BC (aOR 2.25, 95% CI 1.26-4.02). BBD did not significantly mediate the effects of any of the selected BC risk factors. CONCLUSIONS: In this study, BBD was associated with BC and did not significantly mediate the effects of selected BC risk factors.

RESUMO

Purpose: To examine the association between benign breast disease (BBD) and breast cancer (BC) in a heterogeneous population of African women. Methods: BC cases and matched controls were enrolled in three sub-Saharan African countries, Nigeria Cameroon, and Uganda, between 1998-2018. Multivariable logistic regression was used to test the association between BBD and BC. Risk factors dually associated with BBD and BC were selected. Using a parametric mediation analysis model, we assessed if selected BC risk factors were mediated by BBD. Results: Of 6418 participants, 55.7% (3572) were breast cancer cases. 360 (5.7%) self-reported BBD. Fibroadenoma (46.8%) was the most reported BBD. Women with a self-reported history of BBD had greater odds of developing BC than those without (adjusted odds ratio [aOR] = 1.47, 95% CI: 1.13-1.91). Biopsy-confirmed BBD was associated with BC (aOR = 3.11, 95% CI: 1.78-5.44). BBD did not significantly mediate the effects of any of the selected BC risk factors. Conclusions: In this study, BBD was associated with BC and did not significantly mediate the effects of selected BC risk factors.

RESUMO

PURPOSE: Cancer genetic testing (CGT), a pathway to personalized medicine, is also being embraced in Nigeria. However, little is known about the influence of demographics and perceptions on individuals' willingness to access and pay for CGT. This study assessed patients' willingness to undergo CGT in southwest Nigeria as a catalyst for sustainable Cancer Risk Management Program. METHODS: This was a cross-sectional study using semistructured questionnaire to interview 362 patients with cancer and 10 referred first-degree relatives between July 2018 and February 2020. Participants from three Nigerian teaching hospitals-University College Hospital, Ibadan, Lagos State University Teaching Hospital, Lagos, and Lagos University Teaching Hospital, Lagos, received genetic counseling and had subsequent CGT. Primary outcomes were willingness to undergo CGT in determining cancer risk and the willingness to pay for it. Ethical approval was from appropriate ethics committees of participating hospitals. Data were analyzed with SPSS version 22. Univariate comparison of categorical variables was performed by χ2 test, multivariate analysis by logistic regression. RESULTS: The participants from University College Hospital (56.2%), Lagos State University Teaching Hospital (26.3%), and Lagos University Teaching Hospital (17.5%) were mostly female (98.4%). Mean age was 48.8 years ± 11.79. Three hundred twenty-two (86.6%) patients and first-degree relatives were willing to take the test, of whom 231 (71.1%) were willing to pay for it. more than half (53.6%) of the participants were willing to pay between N10,000 and N30,000, which is less than $100 US dollars. Sociodemographic variables and willingness to test showed no association (P > .05). Education and ethnicity were found to be associated with their willingness to pay for CGT (P ≤ .05). CONCLUSION: Learning clinically relevant details toward cancer prevention informs health-related decisions in patients and relatives, a motivator for willingness to pay for genetic testing in low- and middle-income countries. Increased awareness may influence outcomes of cancer risk management.

RESUMO

BACKGROUND: Psychological issues usually accompany the pregnancy of first-time mothers, and psychoeducational interventions might be effective in addressing these concerns and preparing first-time mothers for childbirth and the postnatal period. OBJECTIVE: This study aimed to identify, analyze, and synthesize the components and determine the effectiveness of psychoeducational interventions that are used for managing psychological issues and enhancing birth preparedness among primigravid women or couples in low- and middle-income countries. STUDY DESIGN: A systematic search of 12 databases (APA PsycINFO, EmCare, Embase, MEDLINE(R), Ovid Nursing, British Nursing Index, Health & Medical Collection, ProQuest, CINAHL, Cochrane, Hinari, and PubMed) was conducted to identify relevant studies published between 1946 and October 2021. The quality of the included studies was appraised by the Joanna and Briggs Institute critical appraisal tool, and a narrative synthesis was performed to analyze data extracted from included articles. The systematic review protocol is registered with the International Prospective Register of Systematic Reviews (registration number: CRD42021237896). RESULTS: The initial search yielded 8658 articles. Of note, 16 articles, including 7 randomized controlled trials and 9 nonrandomized trials, met the inclusion criteria and were selected and reviewed for quality. In addition, 31 outcomes were measured in the studies, including psychological outcomes, birth preparedness outcomes, and other outcomes. The design of the interventions included antenatal education that was delivered through lectures, role plays, trainings, and antenatal counseling. All the psychoeducational interventions had a significant effect (P<.05; Cohen's d or Hedges' g=0.2-1.9) on certain psychological outcomes, including childbirth attitude, fear of childbirth, depression, fear, and anxiety, and birth preparedness outcomes. CONCLUSION: Although first-time mothers experience a range of psychological issues during pregnancy, psychoeducational interventions were beneficial in addressing their psychological concerns. It would seem that these interventions are less expensive and could be easily implemented in low- and middle-income countries. However, rigorous research, such as randomized controlled trials, is hereby warranted to standardize the interventions and outcome assessment tools.

RESUMO

BACKGROUND: Few data are available on COVID-19 outcomes among pregnant women in sub-Saharan Africa (SSA), where high-risk comorbidities are prevalent. We investigated the impact of pregnancy on SARS-CoV-2 infection and of SARS-CoV-2 infection on pregnancy to generate evidence for health policy and clinical practice. METHODS: We conducted a 6-country retrospective cohort study among hospitalized women of childbearing age between 1 March 2020 and 31 March 2021. Exposures were (1) pregnancy and (2) a positive SARS-CoV-2 RT-PCR test. The primary outcome for both analyses was intensive care unit (ICU) admission. Secondary outcomes included supplemental oxygen requirement, mechanical ventilation, adverse birth outcomes, and in-hospital mortality. We used log-binomial regression to estimate the effect between pregnancy and SARS-CoV-2 infection. Factors associated with mortality were evaluated using competing-risk proportional subdistribution hazards models. RESULTS: Our analyses included 1315 hospitalized women: 510 pregnant women with SARS-CoV-2, 403 nonpregnant women with SARS-CoV-2, and 402 pregnant women without SARS-CoV-2 infection. Among women with SARS-CoV-2 infection, pregnancy was associated with increased risk for ICU admission (adjusted risk ratio [aRR]: 2.38; 95% CI: 1.42-4.01), oxygen supplementation (aRR: 1.86; 95% CI: 1.44-2.42), and hazard of in-hospital death (adjusted sub-hazard ratio [aSHR]: 2.00; 95% CI: 1.08-3.70). Among pregnant women, SARS-CoV-2 infection increased the risk of ICU admission (aRR: 2.0; 95% CI: 1.20-3.35), oxygen supplementation (aRR: 1.57; 95% CI: 1.17-2.11), and hazard of in-hospital death (aSHR: 5.03; 95% CI: 1.79-14.13). CONCLUSIONS: Among hospitalized women in SSA, both SARS-CoV-2 infection and pregnancy independently increased risks of ICU admission, oxygen supplementation, and death. These data support international recommendations to prioritize COVID-19 vaccination among pregnant women.

RESUMO

PURPOSE: This study investigated the status of training and preparedness for oncology practice and research and degree of interprofessional collaboration among health care professionals in the six geopolitical regions of Nigeria. METHODS: A convergent parallel mixed methods design was used. Three hundred seventeen respondents completed a three-part, online questionnaire. Self-rated competencies in oncology research (26 items), oncology practice (16 items), and interprofessional collaboration (nine items) were assessed with a one- to five-point Likert scale. Six key informant and 24 in-depth interviews were conducted. Descriptive statistics, analysis of variance, and pairwise t-test were used to analyze the quantitative data, whereas thematic analysis was used for the qualitative data. RESULTS: Respondents were mostly female (65.6%) with a mean age of 40.5 ± 8.3 years. Respondents include 178 nurses (56.2%), 93 medical doctors (29.3%), and 46 pharmacists (14.5%). Self-assessed competencies in oncology practice differed significantly across the three groups of health care professionals (F = 4.789, P = .009). However, there was no significant difference across professions for competency in oncology research (F = 1.256, P = .286) and interprofessional collaboration (F = 1.120, P = .327). The majority of respondents (267, 82.4%) felt that educational opportunities in oncology-associated research in the country are inadequate and that this has implications for practice. Key training gaps reported include poor preparedness in data analysis and bioinformatics (138, 43.5%), writing clinical trials (119, 37.5%), and writing grant/research proposals (105, 33.1%). Challenges contributing to gaps in cancer research include few trained oncology specialists, low funding for research, and inadequate interprofessional collaboration. CONCLUSION: This study highlights gaps in oncology training and practice and an urgent need for interventions to enhance interprofessional training to improve quality of cancer care in Nigeria. These would accelerate progress toward strengthening the health care system and reducing global disparities in cancer outcomes.

RESUMO

IMPORTANCE: Little is known about COVID-19 outcomes among children and adolescents in sub-Saharan Africa, where preexisting comorbidities are prevalent. OBJECTIVE: To assess the clinical outcomes and factors associated with outcomes among children and adolescents hospitalized with COVID-19 in 6 countries in sub-Saharan Africa. DESIGN, SETTING, AND PARTICIPANTS: This cohort study was a retrospective record review of data from 25 hospitals in the Democratic Republic of the Congo, Ghana, Kenya, Nigeria, South Africa, and Uganda from March 1 to December 31, 2020, and included 469 hospitalized patients aged 0 to 19 years with SARS-CoV-2 infection. EXPOSURES: Age, sex, preexisting comorbidities, and region of residence. MAIN OUTCOMES AND MEASURES: An ordinal primary outcome scale was used comprising 5 categories: (1) hospitalization without oxygen supplementation, (2) hospitalization with oxygen supplementation, (3) ICU admission, (4) invasive mechanical ventilation, and (5) death. The secondary outcome was length of hospital stay. RESULTS: Among 469 hospitalized children and adolescents, the median age was 5.9 years (IQR, 1.6-11.1 years); 245 patients (52.4%) were male, and 115 (24.5%) had comorbidities. A total of 39 patients (8.3%) were from central Africa, 172 (36.7%) from eastern Africa, 208 (44.3%) from southern Africa, and 50 (10.7%) from western Africa. Eighteen patients had suspected (n = 6) or confirmed (n = 12) multisystem inflammatory syndrome in children. Thirty-nine patients (8.3%) died, including 22 of 69 patients (31.9%) who required intensive care unit admission and 4 of 18 patients (22.2%) with suspected or confirmed multisystem inflammatory syndrome in children. Among 468 patients, 418 (89.3%) were discharged, and 16 (3.4%) remained hospitalized. The likelihood of outcomes with higher vs lower severity among children younger than 1 year expressed as adjusted odds ratio (aOR) was 4.89 (95% CI, 1.44-16.61) times higher than that of adolescents aged 15 to 19 years. The presence of hypertension (aOR, 5.91; 95% CI, 1.89-18.50), chronic lung disease (aOR, 2.97; 95% CI, 1.65-5.37), or a hematological disorder (aOR, 3.10; 95% CI, 1.04-9.24) was associated with severe outcomes. Age younger than 1 year (adjusted subdistribution hazard ratio [asHR], 0.48; 95% CI, 0.27-0.87), the presence of 1 comorbidity (asHR, 0.54; 95% CI, 0.40-0.72), and the presence of 2 or more comorbidities (asHR, 0.26; 95% CI, 0.18-0.38) were associated with reduced rates of hospital discharge. CONCLUSIONS AND RELEVANCE: In this cohort study of children and adolescents hospitalized with COVID-19 in sub-Saharan Africa, high rates of morbidity and mortality were observed among infants and patients with noncommunicable disease comorbidities, suggesting that COVID-19 vaccination and therapeutic interventions are needed for young populations in this region.

RESUMO

BACKGROUND: A high frequency of BRCA mutations has been established in Nigerian breast cancer (BC) patients. Recently, patients' and first-degree relatives' interest have been raised on cancer genetic risk assessment through our awareness activities in Nigeria. This led to the emergence of nurse-led cancer genetic counselling (CGC) and testing aimed at providing standard-of-care for individuals at increased risk of hereditary breast and ovarian cancers. METHODS: In June 2018, CGC and testing of patients with BC and ovarian cancer (OC) commenced in collaboration with Color Genomics Inc. for a 30-panel gene testing. Previously trained nurses in CGC at the University College Hospital, Ibadan offered genetic counselling (GC) to willing patients with BC and gynaecological cancer in four out-patient oncology clinics and departments for the pilot study. Consultation consisted of CGC, patient's history, pedigree and sample collection for genetic testing (GT). RESULTS: Forty-seven patients - 40 with BC, five with OC and two with endometrial cancer received GC, and all chose to undergo GT. The average age at testing was 48.2 ± 12.1 years. Eight women reported a known family cancer history and there were more perceived benefits than barriers to GT with the patients experiencing the desire for none of their relative to have cancer. Results revealed no mutations in 27 (57.4%), 16 (4.0%) variants of unknown significance and 4 (8.5%) pathogenic mutations. CONCLUSION: Personalised cancer care utilises GC and testing for cancer risk assessment towards prevention and early detection in high risk women. The study indicates the necessity of expanded cancer genetic services for integration into patient care and cancer prevention.

RESUMO

The Cancer burden in Africa is increasing. Nurses play a pivotal role in health care systems and find themselves in a key position to engage with patients, communities and other health professionals to address disparities in cancer care and work towards achieving cancer control in Africa. The rapidly evolving nature of cancer care requires a highly skilled and specialised oncology nurse to either provide clinical care and/or conduct research to improve evidence-based practice. Although Africa has been slow to respond to the need for trained oncology nurses, much has been done over the past few years. This article aims to provide an update of Oncology nursing education and training in Africa with specific focus on South Africa, Ghana, Nigeria, Kenya, Zambia and Egypt. Mapping oncology nursing education and training in Africa in 2020, the International Year of the Nurse and the Midwife, provides an opportunity to leverage on the essential roles of the oncology nurse and commit to an agenda that will drive and sustain progress to 2030 and beyond.

RESUMO

Globally, there are prevailing knowledge gaps in the epidemiology, clinical manifestations, and outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among children and adolescents; and these gaps are especially wide in African countries. The availability of robust age-disaggregated data is a critical first step in improving knowledge on disease burden and manifestations of coronavirus disease 2019 (COVID-19) among children. Furthermore, it is essential to improve understanding of SARS-CoV-2 interactions with comorbidities and coinfections such as human immunodeficiency virus (HIV), tuberculosis, malaria, sickle cell disease, and malnutrition, which are highly prevalent among children in sub-Saharan Africa. The African Forum for Research and Education in Health (AFREhealth) COVID-19 Research Collaboration on Children and Adolescents is conducting studies across Western, Central, Eastern, and Southern Africa to address existing knowledge gaps. This consortium is expected to generate key evidence to inform clinical practice and public health policy-making for COVID-19 while concurrently addressing other major diseases affecting children in African countries.

RESUMO

Most African countries have recorded relatively lower COVID-19 burdens than Western countries. This has been attributed to early and strong political commitment and robust implementation of public health measures, such as nationwide lockdowns, travel restrictions, face mask wearing, testing, contact tracing, and isolation, along with community education and engagement. Other factors include the younger population age strata and hypothesized but yet-to-be confirmed partially protective cross-immunity from parasitic diseases and/or other circulating coronaviruses. However, the true burden may also be underestimated due to operational and resource issues for COVID-19 case identification and reporting. In this perspective article, we discuss selected best practices and challenges with COVID-19 contact tracing in Nigeria, Rwanda, South Africa, and Uganda. Best practices from these country case studies include sustained, multi-platform public communications; leveraging of technology innovations; applied public health expertise; deployment of community health workers; and robust community engagement. Challenges include an overwhelming workload of contact tracing and case detection for healthcare workers, misinformation and stigma, and poorly sustained adherence to isolation and quarantine. Important lessons learned include the need for decentralization of contact tracing to the lowest geographic levels of surveillance, rigorous use of data and technology to improve decision-making, and sustainment of both community sensitization and political commitment. Further research is needed to understand the role and importance of contact tracing in controlling community transmission dynamics in African countries, including among children. Also, implementation science will be critically needed to evaluate innovative, accessible, and cost-effective digital solutions to accommodate the contact tracing workload.

RESUMO

Objective: We assessed the knowledge, preparedness, and attitude of health profession students towards COVID-19 outbreak in Sub-Saharan Africa. Methods: This cross-sectional study used convenience sampling to recruit participants from institutions under African Forum for Research and Education in Health (AFREhealth). The survey was developed in QuestionPro software covering the participants' socio-demographic characteristics, knowledge, attitude, and preparedness towards the COVID-19 outbreak. Data were analysed and the association between variables was tested. Results: The mean age of the 336 students was 25•75 (±7•88) years. Most (99•7%) knew the cause of COVID-19 which could be transmitted via droplets (97•3%). Several participants vowed to adhere to preventive measures (92•3%) and claimed their curriculum equipped them with skills addressing infectious disease outbreaks (63•6%). Nursing students were better prepared than other students (p=0•001). Students from West African regions were more prepared (p=0•001) and aware they could contract COVID-19 if they cared for infected persons (p=0•001). Conclusion: Students are knowledgeable about COVID-19, adequately prepared to handle epidemics, have a positive attitude towards infection prevention, and their training institutions and government have taken adequate measures to address the COVID-19 outbreak. Funding: AFREhealth.

RESUMO

BACKGROUND: There is both higher mortality and morbidity from cancer in low and medium income countries (LMICs) compared with high income countries (HICs). Clinical trial activities and development of more effective and less toxic therapies have led to significant improvements in morbidity and mortality from cancer in HICs. Unfortunately, clinical trials remain low in LMICs due to poor infrastructure and paucity of experienced personnel to execute clinical trials. There is an urgent need to build local capacity for evidence-based treatment for cancer patients in LMICs. METHODS: We conducted a survey at facilities in four Teaching Hospitals in South West Nigeria using a checklist of information on various aspects of clinical trial activities. The gaps identified were addressed using resources sourced in partnership with investigators at HIC institutions. RESULTS: Deficits in infrastructure were in areas of patient care such as availability of oncology pharmacists, standard laboratories and diagnostic facilities, clinical equipment maintenance and regular calibrations, trained personnel for clinical trial activities, investigational products handling and disposals and lack of standard operating procedures for clinical activities. There were two GCP trained personnel, two study coordinators and one research pharmacist across the four sites. Interventions were instituted to address the observed deficits in all four sites which are now well positioned to undertake clinical trials in oncology. Training on all aspects of clinical trial was also provided. CONCLUSIONS: Partnerships with institutions in HICs can successfully identify, address, and improve deficits in infrastructure for clinical trial in LMICs. The HICs should lead in providing funds, mentorship, and training for LMIC institutions to improve and expand clinical trials in LMIC countries.

The novel severe acute respiratory syndrome-coronavirus-2 pandemic has spread to Africa, where nearly all countries have reported laboratory-confirmed cases of novel coronavirus disease (COVID-19). Although there are ongoing clinical trials of repurposed and investigational antiviral and immune-based therapies, there are as yet no scientifically proven, clinically effective pharmacological treatments for COVID-19. Among the repurposed drugs, the commonly used antimalarials chloroquine (CQ) and hydroxychloroquine (HCQ) have become the focus of global scientific, media, and political attention despite a lack of randomized clinical trials supporting their efficacy. Chloroquine has been used worldwide for about 75 years and is listed by the WHO as an essential medicine to treat malaria. Hydroxychloroquine is mainly used as a therapy for autoimmune diseases. However, the efficacy and safety of CQ/HCQ for the treatment of COVID-19 remains to be defined. Indiscriminate promotion and widespread use of CQ/HCQ have led to extensive shortages, self-treatment, and fatal overdoses. Shortages and increased market prices leave all countries vulnerable to substandard and falsified medical products, and safety issues are especially concerning for Africa because of its healthcare system limitations. Much needed in Africa is a cross-continental collaborative network for coordinated production, distribution, and post-marketing surveillance aligned to low-cost distribution of any approved COVID-19 drug; this would ideally be piggybacked on existing global aid efforts. Meanwhile, African countries should strongly consider implementing prescription monitoring schemes to ensure that any off-label CQ/HCQ use is appropriate and beneficial during this pandemic.

RESUMO

BACKGROUND: Despite public health policies aimed at providing universal access to reproductive health care services, the reproductive health needs of women living with Human Immunodeficiency Virus (WLHIV) are not adequately met. This study assesses the reproductive plans and utilization of contraceptives among WLHIV. METHODS: This was a cross sectional descriptive study, which adopted a mixed method approach. A total of 400 respondents were recruited from two tertiary health institutions in Nigeria using systematic sampling technique. A validated structured self-administered questionnaire developed by the researcher was used to collect quantitative data for the study. The questionnaire consists of close ended questions related to study objectives. Quantitative data collected were coded and analyzed using Statistical Package for Social Sciences (SPSS) windows version 22 and statistical significance was set at p <0.05. The qualitative aspect of the study utilized focus group discussion for data collection. RESULTS: The mean and standard deviation (SD) age of enrolled respondents was 37.42±7.51 years, and about 59.0 percent were currently married. The prevalence of reproductive desire among WLHIV was comparatively high at 56.5 percent. Furthermore, about 57 percent of the WLHIV had good knowledge of available contraceptives. The current utilization of contraceptive was 47.3 percent. The results revealed significant association between knowledge level of contraceptive options and utilization of contraceptives (X2 = 7.21, df = 1, p =.007), and level of education and utilization of contraceptives (X2 = 21.02, df = 3, p =.001) among women living with HIV. Also, a significant association was found between the respondents' desires to have babies and their knowledge level of contraceptive options that prevent and reduce the risk of vertical transmission of HIV infection (X2= 13.717; P = 0.03). CONCLUSIONS AND GLOBAL HEALTH IMPLICATION: Quality reproductive health service bridges the gaps in the continuum of reproductive health and addresses the risk associated with pregnancy in WLHIV. Integration of reproductive health care in the management of HIV may improve the health of childbearing women living with HIV.

RESUMO

OBJECTIVE: The aim of the descriptive, cross sectional, questionnaire-based study reported here was to explore the causes of low productivity in non-communicable diseases research among postgraduate scholars and early career researchers in Nigeria and identify measures that could facilitate increased research output. RESULTS: The 89 respondents were masters-level, doctoral scholars and resident doctors who attended a workshop. Majorities of the respondents (over 70%) either agreed or strongly agreed that factors contributing to poor non-communicable diseases research productivity include a dearth of in-country researchers with specialized skills, inability of Nigerian researchers to work in multidisciplinary teams, poor funding for health research, sub-optimal infrastructural facilities, and limited use of research findings by policy makers. Almost all the respondents (over 90%) agreed that potential strategies to facilitate non-communicable diseases research output would include increased funding for research, institutionalization of a sustainable, structured capacity building program for early career researchers, establishment of Regional Centers for Research Excellence, and increased use of research evidence to guide government policy actions and programs.

RESUMO

Breast cancer prevalence continues to increase globally, and a significant proportion of the disease has been linked to genetic susceptibility. As we enter the era of precision medicine, genetics knowledge and skills are increasingly essential for achieving optimal cancer prevention and care. However, in Nigeria, patients with breast cancer and their relatives are less knowledgeable about genetic susceptibility to chronic diseases. This pilot study collected qualitative data during in-depth interviews with 21 participants. Of these, 19 participants were patients with breast cancer and two were relatives of patients with breast cancer. Participants were asked questions regarding their knowledge of breast cancer, views on heredity and breast cancer, and views on genetic counseling. Participants' family histories were used as a basis with which to assess their hereditary risk of breast cancer. Participant responses were audio recorded and transcribed manually. The study evaluated patients' and relatives' knowledge of genetic counseling and the use of family history for the assessment of familial risk of breast cancer. This will serve as a guide to the processes of establishing a cancer risk assessment clinic.
