Role and knowledge of nurses in the management of non-communicable diseases in Africa: A scoping review.

BACKGROUND: 31.4 million people in low- and middle-income countries die from chronic diseases annually, particularly in Africa. To address this, strategies such as task-shifting from doctors to nurses have been proposed and have been endorsed by the World Health Organization as a potential solution; however, no comprehensive review exists describing the extent of nurse-led chronic disease management in Africa. AIMS: This study aimed to provide a thorough description of the current roles of nurses in managing chronic diseases in Africa, identify their levels of knowledge, the challenges, and gaps they encounter in this endeavor. METHODS: We performed a scoping review following the key points of the Cochrane Handbook, and two researchers independently realized each step. Searches were conducted using five databases: MEDLINE, PyscINFO, CINAHL, Web of Science, and Embase, between October 2021 and April 2023. A descriptive analysis of the included studies was conducted, and the quality of the studies was assessed using the Downs and Black Scale. RESULTS: Our scoping review included 111 studies from 20 African countries, with South Africa, Nigeria, and Ghana being the most represented. Findings from the included studies revealed varying levels of knowledge. Nurses were found to be actively involved in managing common chronic diseases from diagnosis to treatment. Facilitating factors included comprehensive training, close supervision by physicians, utilization of decision trees, and mentorship. However, several barriers were identified, such as a shortage of nurses, lack of essential materials, and inadequate initial training. CONCLUSION: There is significant potential for nurses to enhance the screening, diagnosis, and treatment of chronic diseases in Africa. Achieving this requires a combination of rigorous training and effective supervision, supported by robust policies. To address varying levels of knowledge, tailored training programs should be devised. Further research is warranted to establish the effectiveness of nurse-led interventions on population health outcomes.

Added Value of Mean Blood Pressure and Placental Growth Factor in the Early Detection of Pre-eclampsia among Gabonese Women.

OBJECTIVE: To evaluate the use of the Foetal Medicine Foundation (FMF) algorithm in routine practice for early pre-eclampsia (PE) screening in Libreville. MATERIALS AND METHODS: We conducted a cohort study on pregnant women within their 11-13 + 6 weeks of gestation (WG). We had measured mean blood pressure (MBP), placental growth factor (PlGF), soluble Fms-like tyrosine kinase 1, Uterine Artery Pulsatility Index (UtA-PI) and resistance index (UtA-RI). Statistical analyses were considered significant for P < 0.05. RESULTS: There were 30 participants. At the first quarter (T1), 36.7% of them were at high risk of PE according to the FMF algorithm and were consequently prescribed aspirin (100 mg/d). By the end of the observation period, we have found a 13% incidence of PE. MBP was higher in the higher risk PE group than in the lower risk group as early as the T1 (90 ± 6 vs. 81 ± 6 mmHg; P = 0.0007, threshold is >86 mmHg/area under the curve (AUC) = 0.86; P = 0.0012). It was the same for PlGF (58 ± 24 vs. 88 ± 38 pg/ml; P = 0.03; threshold is <71.98 pg/ml/AUC = 0.73; P = 0.03). At the second quarter (20-27 WG), biochemical markers did not change between the two groups. UtA-RI, UtA-PI and notch were unconclusive individually, but they are still very important for FMF algorithm application. CONCLUSION: Early detection of PE using the FMF algorithm is possible in routine practice in Gabon. MBP and PlGF levels at T1 seem to be very significant. However, the present study must continue to obtain the larger cohorts that would achieve more conclusive statistical analyses.

Risk Factors Associated with Opportunistic Infections among People Living with HIV/AIDS and Receiving an Antiretroviral Therapy in Gabon, Central Africa.

The Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) is still one of the main causes of death in sub-Saharan Africa. Antiretroviral therapies (ARTs) have significantly improved the health conditions of people living with HIV/AIDS (PLWHA). Consequently, a significant drop in morbidity and mortality, along with a reduced incidence of opportunistic infections (OIs), has been observed. However, certain atypical and biological profiles emerge in ART patients post-examination. The objective of this study was to identify the risk factors that contributed to the onset of OIs in HIV patients undergoing ART in Gabon. Epidemiological and biological data were obtained from medical records (2017 to 2019) found at the outpatient treatment centre (CTA) of Franceville in Gabon. Samples for blood count, CD4, and viral load analysis at CIRMF were collected from PLWHA suffering from other pathogen-induced conditions. A survey was carried out and data were analysed using Rstudio 4.0.2 and Excel 2007 software. Biological and socio-demographic characteristics were examined concerning OIs through both a univariate analysis via Fisher's exact tests or chi2 (χ2), and a multivariate analysis via logistic regression. Out of the 300 participants initially selected, 223 were included in the study, including 154 (69.05%) women and 69 (30.95%) men. The mean age was 40 (38.6; 41.85), with individuals ranging from 2 to 77 years old. The study cohort was classified into five age groups (2 to 12, 20 to 29, 30 to 39, 40 to 49, and 50 to 77 years old), among which the groups aged 30 to 39 and 40 to 49 emerged as the largest, comprising 68 (30.5%) and 75 (33.6%) participants, respectively. It was noted that 57.9% of PLWHA had developed OIs and three subgroups were distinguished, with parasitic, viral, and bacterial infections present in 18%, 39.7%, and 55.4% of cases, respectively. There was a correlation between being male and having a low CD4 T-cell count and the onset of OIs. The study revealed a high overall prevalence of OIs, and extending the study to other regions of Gabon would yield a better understanding of the risk factors associated with the onset of these infections.

Implementation strategy for advanced practice nursing in Gabon: A multicenter mixed-method study.

AIM: To describe the expectations, acceptability, and challenges identified by nurses and key healthcare stakeholders regarding the implementation of advanced practice nursing in Gabon. BACKGROUND: Advanced practice nursing presents an opportunity to address the epidemiological transition and the shortage of healthcare professionals in Africa. In anticipation of establishing a master's degree program in advanced practice nursing and its subsequent implementation, it is important to understand Gabon's specific needs and characteristics. DESIGN: This study used a multicenter cross-sectional mixed-method design. METHODS: From April to May 2022, a total of 187 healthcare professionals were included from two hospitals and two universities in Gabon. Data were collected through questionnaires and complemented by focus group discussions, guided by the existing literature, the PEPPA framework, and Hamric's model. RESULTS: The implementation of advanced practice nursing was generally well accepted. Factors influencing acceptability included being female, awareness of advanced practice nursing, and supporting the role of advanced practice nurses in diagnosing chronic diseases. Barriers to implementation included the absence of a legal framework for the profession and a lack of recognition of nursing skills by both nurses and doctors. Facilitators included the establishment of a master's degree program, formalization of a legal framework, raising awareness, providing training to medical doctors and other healthcare professionals about advanced practice nursing, and the development of nursing leadership. IMPLICATIONS FOR NURSING: Advanced practice nursing can play a crucial role in addressing healthcare resource shortages and the dual burden of chronic and infectious diseases in Gabon, as well as in other African countries. IMPLICATIONS FOR NURSING POLICY: To successfully implement advanced practice nursing in Gabon and French-speaking Africa, it is essential to regulate the nursing and advanced nursing professions by creating a legal framework and establishing nursing councils. An effective implementation strategy for advanced practice nurses should be based on the specific needs of the country. GUIDELINES: COREQ, STROBE.

Allelic frequencies of 22 short tandem repeats loci and tri-allelic patterns of Penta D and TPOX identified in Gabonese population.

Short tandem repeats (STRs) are repeating DNA sequences used in forensic human identity testing and the diagnosis of aneuploidies. Many STRs like Penta D and TPOX are used routinely for paternity tests, but these tests are not widely used in sub-Saharan Africa. In this study we recruited individuals from Gabonese families seeking a paternity test. After DNA extraction from buccal swabs, we genotyped samples using a panel of 22 STRs. A total of 115 unrelated subjects from 39 families were included. Allele frequencies of the 22 STR loci were determined in unrelated Gabonese subjects. The most polymorphic loci were D21S11 (16 alleles) and FGA (17 alleles), while D3S1358 and TH01 loci were less polymorphic, with five alleles each. Deviation from Hardy-Weinberg equilibrium was observed for TPOX, D3S1358, CSFPO and D7S820 loci. We reported tri-allelic patterns that indicate aneuploidies at a combined frequency of 4% (4/115) with 3% for Penta D (1/35) and 3% for TPOX (3/102). Furthermore, we identified a new tri-allelic genotype 5-8-16 for the Penta D locus located on chromosome 21 in a healthy subject. In addition, we observed three tri-allelic variants of TPOX, located on chromosome 2, in healthy subjects, namely 8-10-11, 8-9-10, and 8-8-10. Our study revealed unsuspected polymorphic variations in Penta D and TPOX for the first time in Gabon, raising several questions about chromosomal disorders. Further population genetics studies are needed in Gabon to better characterize these variations, both qualitatively and quantitative.

Molecular epidemiology of antimicrobial resistance in central africa: A systematic review.

Background: In Central Africa, it is difficult to tackle antibiotic resistance, because of a lack of data and information on bacterial resistance, due to the low number of studies carried out in the field. To fill this gap, we carried out a systematic review of the various studies, and devised a molecular epidemiology of antimicrobial resistance from humans, animals and the environmental samples. Method: A systematic search of all publications from 2005 to 2020 on bacterial resistance in Central Africa (Gabon, Cameroon, Democratic Republic of Congo, Central African Republic, Chad, Republic of Congo, Equatorial Guinea, São Tomé and Príncipe, Angola) was performed on Pubmed, Google scholar and African Journals Online (AJOL). All circulating resistance genes, prevalence and genetic carriers of these resistances were collected. The study area was limited to the nine countries of Central Africa. Results: A total of 517 studies were identified through a literature search, and 60 studies carried out in eight countries were included. Among all articles included, 43 articles were from humans. Our study revealed not only the circulation of beta-lactamase and carbapenemase genes, but also several other types of resistance genes. To finish, we noticed that some studies reported mobile genetic elements such as integrons, transposons, and plasmids. Conclusion: The scarcity of data poses difficulties in the implementation of effective strategies against antibiotic resistance, which requires a health policy in a 'One Health' approach.

Assessment of the direct hospital cost of medical care for patients hospitalized for a stroke in Gabon.

While the incidence of stroke is increasing in developing countries, resulting in an extremely high economic burden, very few costing studies have been carried out to date. This study aims to measure the direct hospital costs of stroke management in Gabon. The study adopts a retrospective approach, based on a review of patient records in the Neurology and Cardiology Departments of the University Hospital of Libreville (CHUL) between January 2018 and December 2019. It focuses on all patients received for stroke at the CHUL during the study period, regardless of the outcome, analyzing direct hospital costs. Three hundred and thirteen (313) patients were admitted during the period in question, 72.52% in neurology and 27.48% in cardiology. The average age was 58.44 (±13.73 years). Fifty-six percent (56.23%) had health coverage. Ischemic stroke was more common than hemorrhagic stroke, at 79.55% and 20.45%, respectively. The average expenditure per patient was estimated at 619,633 CFA francs (€944.62). From the point of view of social security coverage, the average out-of-pocket expense per patient was 147,140 CFA francs (€224.31), for a reimbursement of 422,883 CFA francs (€644.68). The average direct cost of stroke is very high for both patients and administrations. This argues for the implementation of prevention programs for the disease. The results of this study may be useful for work on the efficiency of such programs.

Knowledge, attitudes, and practices of mothers regarding childhood malaria in southeastern Gabon.

BACKGROUND: In Gabon, children under 5 years of age and pregnant women are the populations who are most at risk of malaria. Despite the presence of accessible health facilities, the community-based management of childhood fever remains a very common practice in Gabon, which may have serious consequences on child health. As such, the objective of this descriptive cross-sectional survey is to assess the mothers' perception and knowledge of malaria and its severity. METHODS: Different households were selected using the simple random sampling method. RESULTS: A total of 146 mothers from different households were interviewed in the city of Franceville, in southern Gabon. Among the households interviewed, 75.3% had a low monthly income (below the minimum monthly income of $272.73). Among the respondents, 98.6% of mothers had heard of malaria and 55.5% had heard of severe malaria. Regarding preventive measures, 83.6% of mothers used an insecticide-treated net as a means of protection. Self-medication was practiced by 68.5% of women (100/146). DISCUSSION: The use of health facilities was motivated by better care, the decision of the head of the family, but above all by the severity of the disease. Women identified fever as the main symptom of malaria, which could be beneficial for a quicker and more efficient management of the disease in children. Malaria educational campaigns should also increase awareness of severe forms of malaria and its manifestations. This study shows that Gabonese mothers react quickly when their children have fever. However, several external factors lead them to practice self-medication as a first resort. In this survey population, the practice of self-medication did not depend on social status, marital status, level of education, on the young age or inexperience of mothers (p > 0.05). CONCLUSIONS: The data revealed that mothers may underestimate severe malaria and delay medical care by self-medicating, which can have detrimental effects for children and hinder the regression of the disease.

Severe malaria in children and adolescents in Southeast Gabon.

INTRODUCTION: Malaria remains a significant public health problem in sub-Saharan Africa. Child mortality due to severe malaria remains high in developing countries despite improvements in malaria management and a better understanding of its pathophysiology. To address the lack of epidemiological studies on severe malaria in Gabon, this study describes the epidemiological aspects of severe malaria in rural, semi-rural, and urban areas of southeast Gabon. METHODS: Demographic, clinical, and laboratory data for children and adolescents aged 0-18 years were collected in 2019 from hospital records at three health facilities in southeastern Gabon. The patients included in the study were positive for P falciparum malaria diagnosed by microscopy with at least one of the malaria severity criteria. RESULTS: Severe malaria accounted for 18.8% (667/3552) of malaria cases. Children aged 0-5 years accounted for 71.8% (479/667) of all severe malaria cases. Adolescents over 15 years of age were the least affected by severe malaria with 4.2% (28/667). Across the study, severe anemia (49.0%, 327/667), convulsions (43.0%, 287/667), respiratory distress (5.1%, 34/667), and altered consciousness (4.8%, 32/667) were the most frequent clinical signs of severe malaria in children. Franceville was the locality most affected by severe malaria with 49.2% (328/667), followed by Koulamoutou with 42.0% (280/667) and Lastourville with 8.8% (59/667). Convulsions (50.6%, 166/328) and coma (6.1%, 20/328) were more frequent in children living in urban areas. In contrast, severe anemia (56.7%, 186/339) and jaundice (6.8%, 23/339) were more common in children living in semi-rural areas. CONCLUSION: Severe malaria is more prevalent in urban areas in regions with a high malaria transmission intensity. However, in this study, the epidemiological characteristics of severe malaria were similar in the three settings (urban, rural, and semi-rural areas) despite different levels of urbanization. Nevertheless, the various signs of severity were more frequent in Franceville, an urban area. Children under 5 years of age remain the most vulnerable age group.

Prevalence and Phenotypic and Molecular Characterization of Carbapenemase-Producing Gram-Negative Bacteria in Gabon.

Data collection and monitoring of carbapenemase-producing (CP) Gram-negative bacteria (GNB) are often limited. This study determined CP-GNB prevalence in Gabon and the genetic origins of the resistance genes. From January 2016 to March 2018, 869 clinically significant GNB isolates from inpatients and outpatients, and 19 fecal samples (inpatients) were analyzed in the main hospitals of Gabon. Fecal samples were screened using ChromID® CARBA SMART selective chromogenic medium biplates. Species were identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry. Antibiotic susceptibility was tested using the disk diffusion method on Müller-Hinton agar, and resistance genes were assessed by multiplex polymerase chain reaction and sequencing. Overall, 1.61% of clinical isolates (14 of 869) and 5.26% of fecal samples (1 of 19) were CP-GNB. The CP-GNB rate was higher among inpatients (2.98%) than outpatients (0.33%), in intensive care units (28.57%, 4 of 14), and in urine samples (35.71%, 5 of 14). The most common CP-GNB were Klebsiella pneumoniae (53.33%) and Acinetobacter baumannii (26.67%). blaOXA-48 was the predominant carbapenemase-encoding gene (40%), followed by blaNDM-5 (33.33%). The A. baumannii multilocus sequence types ST2 and ST78, Enterobacter cloacae ST78, Escherichia coli ST2, and K. pneumonia ST48 and ST147 were found. These data indicate that CP bacteria are present in clinical and carriage samples. Preventive measures are needed to avoid the spread of resistance genes.

Epidémiology of malaria from 2019 to 2021 in the southeastern city of Franceville, Gabon.

BACKGROUND: In Gabon, a new national malaria control policy was implemented in 2003. It resulted in a decrease in the number of malaria cases in the country. In March 2020, the disruption of routine health services due to the COVID-19 pandemic has led to an increase in cases and deaths due to malaria. However, in Franceville, south-east Gabon, no data on malaria cases recorded before, during and after the COVID-19 epidemic has been published. Thus, the objective of this study was to determine the epidemiological characteristics of malaria in Franceville from 2019 to 2021. METHODS: A retrospectively study of malaria cases was performed at the Hôpital de l'Amitié Sino-Gabonaise (HASG). Information regarding age, gender, malaria diagnosis by microscopy and hematology cell count were collected from laboratory registers from June 2019 to December 2021. Malaria data were analyzed and correlated with seasonal variations. RESULTS: The data of 12,695 febrile patients were collected from the laboratory registers of the HASG, among which 4252 (33.5%) patients were found positive for malaria. The malaria prevalence was 37.5% in 2020 year. This prevalence was highest compared to the 2019 (29.6%) and 2021 (31.5%) year (p < 0.001). During the short rainy season (October to December), a large increase in malaria cases was observed all three year, from 2019 to 2021 (p > 0.05). CONCLUSION: The prevalence of malaria in Franceville was very high during COVID-19 pandemic. It is therefore necessary to strengthen existing interventions and implement more effective interventions.

Evaluation of the intention to use the electronic medical record (EMR) by health professionals in healthcare facilities of Libreville and Owendo in Gabon.

Introduction: Health systems in several countries have integrated information and communication technologies into their operations. Electronic medical records (EMRs) are at the core of patient care. The working of these EMRs requires their acceptance and use by medical and paramedical personnel. The objective of this study was to empirically evaluate the intention of health professionals to use these EMRs. Materials and Methods: A questionnaire on the intention of health professionals to use the EMR was developed following a Likert scale. The survey was done via in-person interviews of health professionals in major health facilities in the cities of Libreville and Owendo in Gabon. The technology acceptance model (TAM) was tested using a step-down logistic regression analysis to identify the main factors explaining the intention of health professionals to use the EMR. Results: A total of 218 health professionals responded to the questionnaire. Thirty-eight percent (38%) of respondents were male. The average age was 41.33 years (±8.98 years) and the average length of service at work in the system was 12.02 years (±8.47 years). The integrated model showed that the intention to use the EMR was significantly associated with the perceived usefulness, the subjective standard, and experience. No socio-demographic variables explained the intention to use the EMR. Conclusion: The perceived ease, familiarity with the computer, and motivation are not associated with the intention to use the EMR. Actions should be taken to raise awareness and train health professionals to motivate them to accept and use EMRs in their medical practices.

From Real-world Individuals' Data to National Health Indicators: Multiphase Pilot Study in Gabon.

BACKGROUND: Achieving health goals requires informed decision-making supported by transparent, reliable, and relevant health information. This helps decision makers, such as health managers, to better understand the functioning of their health system and improve their ability to respond quickly to health demands. To achieve this, the health system needs to be supported by a digitized decision-making information system. In Sub-Saharan African countries, inadequate digital infrastructure, including limited internet connectivity and insufficient access to appropriate computer software, makes it difficult to collect, process, and analyze data for health statistics. The processing of data is done manually in this case; however, this situation affects the quality of the health statistics produced and compromises the quality of health intervention choices in these countries. OBJECTIVE: This study aimed to describe the conceptual approach of a data production and dissemination platform model proposed and implemented in Gabon. More precisely, it aimed to present the approach applied for the multidimensional analysis of the data production and dissemination process in the existing information system and present the results of an evaluation of the proposed model implemented in a real context. METHODS: The research was carried out in 3 phases. First, a platform was designed and developed based on the examination of the various data production and indicator generation procedures. Then, the platform was implemented in chosen health facilities in Gabon. Finally, a platform evaluation was carried out with actual end users. RESULTS: A total of 14 users with 12 years of average experience in health data management were interviewed. The results show that the use of the proposed model significantly improved the completeness, timeliness, and accuracy of data compared with the traditional system (93% vs 12%, P<.001; 96% vs 18%, P<.001; and 100% vs 18%, P<.001; respectively). CONCLUSIONS: The proposed model contributes significantly to the improvement of health data quality in Gabon.

Prevalence and factors associated to gestational diabetes mellitus among pregnant women in Libreville: a cross-sectional study.

Introduction: mainly occurring in low and middle income countries, gestational diabetes mellitus (GDM) represents 84% of hyperglycemia during pregnancy throughout the world. Moreover, being black is a risk factor to develop the disease. Our objective was to determine the prevalence and the associated factors of GDM in Libreville (Gabon). Methods: a cross-sectional study was carried out. Known diabetic women were excluded from the study and we had submitted asymptomatic pregnant women to a 2 steps 75g oral glucose tolerance test (T0-T2H), regardless of the stage of pregnancy at the moment of recruitment. The threshold for positivity was set at blood glucose level ≥ 8.5mmol/L World Health Organization (WHO 2013 threshold) and ≥ 7.8mmol/L (WHO 1999 threshold). Data were analyzed using Statview® for descriptive statistics, for both bivariate and multivariate analysis. Results: among 245 participants, we have found a GDM prevalence of 10.2% according to WHO 1999 threshold and 4.5% according to WHO 2013 threshold. Applying the WHO 1999 threshold, the associated factors were high maternal weight (p= 0.0498), overweight at recruitment (p=0.0246), personal history of GDM (p< 0.0001), age becomes an associated factor only if it is combined with high parity (p=0.0061). ceaserian-section and macrosomia were the two outcomes of GDM. Conclusion: Libreville has a high prevalence of GDM when the WHO 1999 criteria is compared to the WHO 2013 criteria. Discordance is also found with the identified associated factors. Further studies are needed to better appreciate gestational diabetes in Gabon.

Health information systems in developing countries: case of African countries.

BACKGROUND: In developing countries, health information system (HIS) is experiencing more and more difficulties to produce quality data. The lack of reliable health related information makes it difficult to develop effective health policies. In order to understand the organization of HIS in African countries, we undertook a literature review. METHODS: Our study was conducted using the PubMed and Scopus bibliographic search engines. The inclusion criteria were: (i) all articles published between 2005 and 2019, (ii) articles including in their title the keywords "health", "information", "systems", "system", "africa", "developing countries", "santé", "pays en développement", "Afrique", (iii) articles that are written in English or French, (iv) which deals with organizational and technical issues about HIS in African countries. RESULTS: Fourteen retrieved articles out of 2492 were included in the study, of which 13 (92.9%) were qualitative. All of them dealt with issues related to HIS in 12 African countries. All 12 countries (100.0%) had opted for a data warehouse approach to improve their HIS. This approach, supported by the DHIS2 system, has enabled providing reliable data. However, 11 out of the 12 countries (92.0%) frameworks were aligned with funding donors' strategies and lacked any national strategy. CONCLUSION: This study suggests that the lack of a national health information management strategy will always be a threat to HIS performance in African countries. Ideally, rigorous upstream thinking to strengthen HIS governance should be undertaken by defining and proposing a coherent conceptual framework to analyze and guide the development and integration of digital applications into HIS over the long term.

Evaluation of direct costs associated with the management of clinical stage of malaria in children under five years old in Gabon.

BACKGROUND: Malaria is one of the leading causes of morbidity and mortality in African countries. It is one of the leading causes of hospital visits and hospitalization in pediatric wards for children under 5 years old. Interestingly however, the economic burden of this disease remains unknown in these endemic countries including Gabon. The purpose of this study is to assess the direct hospital cost for the management of malaria in children under 5 years old at the Libreville University Hospital Centre (CHUL, Centre Hospitalier Universitaire de Libreville) in Gabon. METHODS: This research work is a retrospective study using a comprehensive review of medical records of patients seen at the CHUL over a two-year period extending from January 2018 through December 2019. The study focused on children under 5 years old, admitted for malaria in the paediatric ward of the CHUL. The analysis targeted specifically direct hospital costs, which excluded salary and wages of health care workers. The monetary currency used in this study was the CFA francs, as that currency is the one used in Central Africa (as reference, 1 Euro = 656 CFA francs). RESULTS: For the set timeframe, 778 patient records matched the study criteria. Thus, out of 778 admitted patients, 58.4% were male while 41.5% were female. Overall, the average age was 13.2 months (± 13.8 months). The total cost incurred by the hospital for the management of these 778 malaria patients was 94,922,925 CFA francs (144,699.58 €), for an average expense per patient topping at 122,008 CFA francs (185.99 €). The highest expenditure items were hospitalizations (44,200,000 CFA francs, 67,378.1 €), followed by drugs (26,394,425 CFA francs, 40,235.4 €) and biomedical examinations (14,036,000 CFA francs, 21,396.34 €). CONCLUSION: The financial burden for managing malaria in the paediatric ward seems to be very high, not only for the hospital, but also for families in spite of the government medical insurance coverage in some cases. These findings bring new insights as to the urgency to develop policies that foster preventive initiatives over curative approaches in the management of malaria in children in endemic countries.

Prevalence and Characterization of Extended-Spectrum Beta-Lactamase-Producing Enterobacteriaceae in Major Hospitals in Gabon.

In Gabon, few data exist on extended-spectrum beta-lactamases-producing Enterobacteriaceae (ESBL-PE). This study investigated ESBL-PE prevalence and the associated resistance genes in clinical samples (n = 5,956) and anal swabs (n = 78) analyzed in eight hospitals and a medical analysis laboratory in Gabon from January 2016 to March 2018. Matrix-Assisted Laser Desorption Ionization-Time Of Flight (MALDI-TOF) mass spectrometry analysis identified 790 Enterobacteriaceae isolates (n = 712 clinical samples and n = 78 fecal samples). ESBL-PE prevalence (Müller-Hinton agar disk diffusion method and double-disk synergy test) was 11.8% (84/712) in clinical samples (15.5% from inpatients and 7.1% from outpatients; p < 0.05) and 16.7% (13/78) in carriage isolates. Most ESBL-PE were isolated from urine samples (46/84). In clinical and carriage ESBL-PE isolates, Escherichia coli was predominant (42.8% and 61.5%; phylogroups A, B1, B2, and D), followed by Klebsiella pneumoniae (41.7% and 23.1%). Multiplex PCR and bi-directional sequencing showed that CTX-M group 1 (blaCTX-M-15) was predominant in clinical and carriage ESBL-PE (94% and 92.3%) among which 85.7% and 92.3% also harbored one to three ß-lactamase-encoding genes (blaTEM-1, blaOXA-1, or blaSHV-1). Resistance genes were detected in all hospitals in Gabon. ESBL-PE prevalence in Gabon has not reached alarming levels yet, but corrective and monitoring measures are needed to curb their emergence.

[Assessment of vaccination status and booster vaccinations in adolescents attending school in Libreville, Gabon]. / Evaluation du statut vaccinal et des rappels vaccinaux chez les adolescents scolarisés à Libreville, au Gabon.

INTRODUCTION: Vaccination is targeted to selected adolescents and their vaccination status is little known. The purpose of this study is to assess the vaccination status and to identify factors associated with vaccination compliance in adolescents attending school in Libreville. METHODS: A cross sectional observational descriptive survey was conducted among students attending grades 6 at the Leon Mba high school in Libreville. RESULTS: In total, 304 students were included in the study. The average age of students was 11.60±1.20 years and sex ratio was 0.6. Two hundred and sixty-six children (87.5%) lived with their parent (father and/or mother). The average number of children per family was 4. Immunization coverage rate was 78.3%. The number of children per family was not associated with vaccine coverage of Expanded Program on Immunization (EPI) vaccines (p=0.088) while children living with at least one of their parents had a better immunization coverage for EPI vaccines (p=0.025) and vaccines outside EPI (p=0.035) respectively. Factors reported by parents to explain reasons for non-vaccination were the lack of information (30.59%), forgetfulness (24.67%) and the lack of financial resources (12.82%). CONCLUSION: Vaccination coverage for adolescents attending school in Libreville appears to be relatively close to the goals of EPI, but it is still associated with family situation. Other awareness campaigns would be useful to improve vaccination coverage in Gabon.

Screening Questionnaires to Detect Neurological Disorders in Developing Countries: A Systematic Review.

INTRODUCTION: Neurological disorders are an important cause of disability and death worldwide. The distribution of these disorders differs significantly in developing countries. Screening questionnaires have been used as an important tool to detect neurological illnesses. This systematic literature review aimed to report the validity of screening questionnaires for neurological disorders in developing countries. METHODS: The PubMed/MEDLINE, Scopus, Science-Direct, and PASCAL databases were searched. All published studies performed in developing countries were eligible. The risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies version 2 tool. Summary measures of validity were reported (sensitivity and specificity). RESULTS: Eight hundred and thirty-five records were identified, and 49 articles that met eligibility criteria were selected. The most frequently neurological disorders detected with a screening tool were epilepsy, stroke, and neuropathies (77, 53, and 40%, respectively). Ten screening questionnaires were accessible. Two questionnaires were mainly used to detect neurological disorders: the World Health Organization Protocol for Epidemiologic Studies of Neurologic Disorders and the Ten Questions Questionnaire. The sensitivity of the questionnaires was ranged from 84 to 100% and 56 to 100%, respectively. CONCLUSION: This systematic review presents evidence that screening questionnaires are valid tools to detect neurological disorders in developing countries. Disease detection provides epidemiological data and the opportunity to implement secondary and tertiary prevention strategies that will contribute to reduce the global burden of neurological disorders.

Impact of knowledge, attitudes, and sociocultural factors on school enrollment of children with epilepsy in Gabon.

PURPOSE: Perceptions, beliefs and culture influence attitude towards epilepsy in sub-Saharan Africa. Misconceptions on epilepsy contribute to the persistence of negative attitudes in children with epilepsy particularly on their school enrollment. The aim of the study was to assess knowledge, attitudes, and sociocultural factors affecting schooling of children with epilepsy in Gabon. METHODS: Teachers and health workers from two urban and four rural localities of Gabon were assessed using a self-administered questionnaire. RESULTS: Overall 1310 subjects filled the survey questionnaire, including 813 teachers and 497 health workers. Knowledge on risk factors and suggestive signs of childhood epilepsy were globally poor. Misconceptions on etiology of epilepsy were significant with contagiousness (27.5%) and demonic possession (16.0%) representing the major prevalent idea about the origin of epilepsy in children. Attitudes of teachers and health workers towards schooling of children with epilepsy were positive (85.0%). However, more than half recommended enrollment of these children in specialized school programs. In multivariate analysis, education level (OR = 1.40; 95% confidence interval 1.01-1.81) and marital status (OR = 1.62; 95% confidence interval 1.18-2.22) were sociocultural factors likely to affect chances of school enrollment of children with epilepsy. CONCLUSION: Understanding the influence of socio-cultural factors surrounding school enrollment of children with epilepsy could enhance public awareness campaigns about epilepsy and to improve school integration of these children.
