Community perceptions of a biopsychosocial model of integrated care in the health center: the case of 4 health districts in South Kivu, Democratic Republic of Congo.

BACKGROUND: Biopsychosocial care is one of the approaches recommended in the health system by the WHO. Although efforts are being made on the provider side to implement it and integrate it into the health system, the community dynamic also remains to be taken into account for its support. The objective of this study is to understand the community's perceptions of the concept of integrated health care management according to the biopsychosocial approach (BPS) at the Health Center of a Health District and its evaluation in its implementation. METHODS: This cross-sectional study was done in six Health Areas belonging to four Health Districts in South Kivu, DRC. We conducted 15 semi-directive individual interviews with 9 respondents selected by convenience, including 6 members of the Development Committees of the Health Areas, with whom we conducted 12 interviews and 3 patients met in the health centers. The adapted Normalization MeAsure Development (NoMAD) tool, derived from the Theory of the Normalization Process of Complex Interventions, allowed us to collect data from November 2017 to February 2018, and then from November 2018 to February 2019. After data extraction and synthesis, we conducted a thematic analysis using the NoMAD tool to build a thematic framework. Six themes were grouped into three categories. RESULTS: Initially, community reports that the BPS approach of integrated care in the Health Centre is understood differently by providers; but then, through collective coordination and integrated leadership within the health care team, the approach becomes clearer. The community encouraged some practices identified as catalysts to help the approach, notably the development of financial autonomy and mutual support, to the detriment of those identified as barriers. According to the community, the BPS model has further strengthened the performance of health workers and should be expanded and sustained. CONCLUSIONS: The results of our study show the importance of community dynamics in the care of biopsychosocial situations by providers. The barriers and catalysts to the mechanism, both community-based and professional, identified in our study should be considered in the process of integrating the biopsychosocial model of person-centered health care.

Erectile dysfunction in copper and cobalt miners: a cross-sectional study in the former Katanga province, Democratic Republic of the Congo.

Background: The African Copperbelt is a site of intense artisanal and industrial mining and refining of copper and cobalt. Aim: We aimed to investigate factors that are possibly associated with erectile dysfunction (ED) in metal miners in the former Katanga province of the Democratic Republic of the Congo. Methods: In a cross-sectional study of 138 miners and 139 controls (bakers), we administered questionnaires to obtain sociodemographic and occupational data and to assess male sexual function (International Index of Erectile Function [IIEF]) and marital relation quality (Revised Dyadic Adjustment Scale). Furthermore, we measured trace metals in blood and urine, as well as testosterone and thyroid hormones in serum. Outcomes: Outcomes included the prevalence of questionnaire-derived ED and the relation of ED with individual characteristics, serum testosterone, and environmental factors. Results: Miners were on average 4 years older than bakers (mean ± SD, 37.5 ± 6.9 vs 33.3 ± 5.7 years). Miners had significantly lower scores than bakers on the IIEF (median [IQR], 66 [49-73] vs 73 [66-74]) and the 3 domains of the Revised Dyadic Adjustment Scale (consensus, satisfaction, cohesion). Free testosterone was significantly lower in miners than bakers (ng/dL; 8.11 [6.90-10.10] vs 10.52 [8.83-12.58]; P ˂ .001). In miners, sex hormone-binding globulin correlated positively with blood Pb and urinary Cd. In a multivariable analysis, mild to moderate ED or moderate ED (IIEF-erectile function score ≤18) was significantly associated with having a mining-related job (adjusted odds ratio [aOR], 2.6; 95% CI, 1.3-5.3), work seniority ˃5 years (aOR, 2.3; 95% CI, 1.1-4.6), alcohol consumption (aOR, 2.8; 95% CI, 1.2-6.7), and aphrodisiacs use (aOR, 4.2; 95% CI, 2.2-8.0). Mediation analysis showed that marital relationship partially mediated the relation between work seniority >5 years in mining and ED. Clinical Implications: The high prevalence of ED found in artisanal mine workers indicates that work-related factors should be considered as possibly contributing, directly or indirectly, to sexual dysfunction in men. Strengths and Limitations: Strengths include being the first epidemiologic study documenting ED with validated questionnaires and its possible determinants, including exposure to toxic metals, among young artisanal miners vs a suitable control group. Limitations are the cross-sectional design with convenience sampling and absence of objective confirmation of ED. Conclusion: As compared with controls, miners reported poorer sexual function and lower quality of their marital relationship, and they had lower free testosterone levels, which may be due to their high exposure to trace metals.

Profile of health care workers in a context of instability: a cross-sectional study of four rural health zones in eastern DR Congo (lessons learned).

BACKGROUND: The crisis in human resources for health is observed worldwide, particularly in sub-Saharan Africa. Many studies have demonstrated the importance of human resources for health as a major pillar for the proper functioning of the health system, especially in fragile and conflict-affected contexts such as DR Congo. However, the aspects relating to human resources profile in relation to the level of performance of the health districts in a particular context of conflicts and multiform crises have not yet been described. OBJECTIVE: This study aims to describe the profile of staff working in rural health districts in a context of crisis and conflicts. METHODS: A cross-sectional study was carried out from May 15, 2017 to May 30, 2019 on 1090 health care workers (HCW) exhaustively chosen from four health districts in Eastern Democratic Republic of Congo (Idjwi, Katana, Mulungu and Walungu). Data were collected using a survey questionnaire. The Chi2 test was used for comparison of proportions and the Kruskal-Wallis test for medians. As measures of association, we calculated the odds ratios (OR) along with their 95% confidence interval. The α-error cut-off was set at 5%. RESULTS: In all the health districts the number of medical doctors was very insufficient with an average of 0.35 medical doctors per 10,000 inhabitants. However, the number of nurses was sufficient, with an average of 3 nurses per 5000 inhabitants; the nursing / medical staff (47%) were less represented than the administrative staff (53%). The median (Min-Max) age of all HCW was 46 (20-84) years and 32% of them were female. This was the same for the registration of staff in the civil service (obtaining a registration number). The mechanism of remuneration and payment of benefits, although a national responsibility, also suffered more in unstable districts. Twenty-one percent of the HCW had a monthly income of 151USD and above in the stable district; 9.2% in the intermediate and 0.9% in the unstable districts. Ninety-six percent of HCW do not receive Government' salary and 64% of them do not receive the Government bonus. CONCLUSION: The context of instability compromises the performance of the health system by depriving it of competent personnel. This is the consequence of the weakening of the mechanisms for implementing the practices and policies related to its management. DR Congo authorities should develop incentive mechanisms to motivate young and trained HCW to work in unstable and intermediate health districts by improving their living and working conditions.

Occupational rhinitis and asthma in bakers: a cross-sectional study in the former Katanga province of DR Congo.

OBJECTIVE: Bakers are at high risk of rhinitis and asthma, but the prevalence of these occupational diseases is not well known in Sub-Saharan Africa. We investigated the prevalence of occupational rhinitis and asthma among industrial bakers in the former province of Katanga. METHODS: In a cross-sectional study conducted in eight towns from October 2018 to September 2019, we included 276 male workers from 18 industrial bakeries and 113 male controls (35 butchers and 78 bread sellers), all nonsmokers. Participants replied to a validated questionnaire (European Community of Respiratory Health Survey II), administered face to face, and performed spirometry at the work place. In 15 bakers with symptoms of work-related asthma, records of self-measured peak expiratory flow (PEF) 4 times per day during 4 weeks were analyzed by the OASYS (Occupational Asthma System) protocol. RESULTS: The bakers and controls did not differ by age (32.2 ± 7.3 y vs 32.8 ± 10.3 y). According to the questionnaire, work-related rhinitis and asthma were significantly more prevalent among bakers (31% and 5%, respectively) than among controls (2% and 0%, respectively). However, the groups did not differ significantly with regard to spirometric parameters. Based on PEF records, 10 out of 15 were positive for occupational asthma (OASYS score > 2.5), so the rate of occupational asthma was 3.6% in this study. CONCLUSION: This first study in DR Congo demonstrates the existence of occupational rhinitis and asthma among industrial bakers in Katanga. Further epidemiological studies are needed to clarify the extent and risk factors of baker's asthma in the area. In the meantime, advocacy and implementation of appropriate occupational hygiene measures are warranted to protect bakery workers in DR Congo.

Les indicateurs de l'alimentation du nourrisson et du jeune enfant prédicteurs de la malnutrition chez les enfants 6-23 mois dans la zone de santé de Kapolowe, Haut-Katanga, R D Congo / NA

Introduction. L'étude visait évaluer les indicateurs de l'alimentation du nourrisson et du jeune enfant liés à l'état nutritionnel dans la zone de santé de Kapolowe, province du Haut Katanga avant les essais cliniques. Matériel et méthodes. Nous avons conduit une étude descriptive transversale dans la communauté auprès des 568 couples mère-enfant 6-23 mois évalués sur les indicateurs nutritionnels associés à la malnutrition. Résultats. L'allaitement maternel optimal était observé chez 10,7% des couples mère-enfant et l'alimentation complémentaire adéquate bénéficiée par 5,5% des enfants. Presque 25,6% des ménages utilisaient des toilettes améliorées, 98,8% des ménages buvaient l'eau des sources protégées et 12,1% des mères pratiquaient un minimum de lavage de mains. Le premier aliment complémentaire donné à la moitié des enfants (46%) était importé, mais 60,3 % des mères utilisaient le mélange farine de maïs + huile + sucre comme aliment de complément. La prévalence de la malnutrition aiguë, de la malnutrition chronique et de l'insuffisance pondérale était respectivement de 11,9%, 37% et 26,8%. La malnutrition aiguë était associée à l'occupation de la mère, au niveau socio-économique du ménage, à la Religion de la mère, à la consultation prénatale suivie par la mère, au Minimum de Diversité Alimentaire, à l'allaitement maternel non optimal, aux infections récurrentes et au faible poids de naissance. L'insuffisance pondérale était associée au sexe, à l'occupation de la mère, au niveau socio-économique, à la religion de la mère, au minimum de diversité alimentaire, à l'allaitement maternel non optimal, aux infections récurrentes et au faible poids de naissance. La malnutrition chronique était associée au sexe, au niveau socio-économique,

Introduction. The aim of the study was to assess infant and young child feeding indicators related to nutritional status in the Kapolowe health zone, Haut Katanga province prior to the clinical trials. Material and methods. We conducted a descriptive cross-sectional study in the community among568 mother-child pairs 6-23 months of age assessed on nutritional indicators associated with malnutrition. Results. Optimal breastfeeding was observed in 10.7% of the mother-child pairs and adequate complementary feeding in 5.5%. Almost 25.6% of households used improved toilets, 98.8% of households drank water from protected springs and 12.1% of mothers practiced minimal hand washing,12.1% of mothers practiced minimal handwashing. The first supplementary food given to half of the children (46%) was imported food, but 60.3% of mothers used maize flour + oil + sugar as a complementary food. The prevalence of acute malnutrition, chronic malnutrition and under weight were 11.9%, 37% and26.8% respectively. Acute malnutrition was associated with the mother's occupation, household socio-economic level, mother's religion, prenatal consultation attended by the mother, minimum dietary diversity, non-optimal breastfeeding, recurrent infections, and low birth weigh. Underweight was associated with gender, maternal occupation, socio-economic level, maternal religion, minimum dietary diversity, non-optimal breastfeeding, recurrent infections and low birth weight. Chronic malnutrition was associated with gender, socio-economic level, minimum meal frequency, type of toilet used, non-optimal breastfeeding, recurrent infections, and low birth weight. Conclusion. The prevalence of malnutrition, in all its forms, is still very high and worrying among children aged 6-23 months. The feeding practices are predictors of it.

The Critical Need for Pooled Data on Coronavirus Disease 2019 in African Children: An AFREhealth Call for Action Through Multicountry Research Collaboration.

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.

Knowledge, preparedness, and attitude towards COVID-19 among health profession students in Sub-Saharan Africa: A cross-sectional survey.

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.

Integration of Human African Trypanosomiasis Control Activities into Primary Healthcare Services: A Scoping Review.

Human African trypanosomiasis (HAT) also known as sleeping sickness is targeted for elimination as a public health problem by 2020 and elimination of infection by 2030. Although the number of reported cases is decreasing globally, integration of HAT control activities into primary healthcare services is endorsed to expand surveillance and control. However, this integration process faces several challenges in the field. This literature review analyzes what is known about integrated HAT control to guide the integration process in an era of HAT elimination. We carried out a scoping review by searching PubMed and Google Scholar data bases as well as gray literature documents resulting in 25 documents included for analysis. The main reasons in favor to integrate HAT control were related to coverage, cost, quality of service, or sustainability. There were three categories of factors influencing the integration process: 1) the clinical evolution of HAT, 2) the organization of health services, and 3) the diagnostic and therapeutic tools. There is a consensus that both active and passive approaches to HAT case detection and surveillance need to be combined, in a context-sensitive way. However, apart from some documentation about the constraints faced by local health services, there is little evidence on how this synergy is best achieved.

Concurrent exposure to heavy metals and cognition in school-age children in Congo-Kinshasa: A complex overdue research agenda.

The impact of concurrent exposure to neurotoxic metals is a significant threat to brain function, mostly in contexts of multiple exposures as seen in the developing world. Ninety-five children (46 boys and 49 girls, 6 to 11-year old) from Congo-Kinshasa were assessed for cognition using the Kaufman Assessment Battery for Children (2nd edition) and exposure to Cr, Cu, Zn, Co, Mn, As, Cd, Se, Hg, Fe, and Pb by inductively coupled plasma mass spectrometry (ICPMS) in serum and urine collections. Concentrations of elements were all above normal ranges except for Cd, Se and Hg. General linear mixed effects models were used to predict neurocognitive outcomes with variable selection methods including backward elimination, elastic net, or subsets identified based on subject matter expertise. After adjusting for sex, age, and SES, urinary Co > 5 µg/l was associated with poor simultaneous processing (memory) (p = 0.0237). Higher excretion but normal concentration of Cd in serum was associated with better memory (p = 0.03), planning (p = 0.05), and overall performance scores (p < 0.01); thus appeared to be neuroprotective. However, higher excretion of Zn had negative influence on the overall performance scores (p = 0.02). Predictive neurotoxicology is a challenging task in contexts of multiple and concurrent exposures. Urinary Co > 5 µg/l is a risk factor for poor neurodevelopmental outcomes in such contexts. The impact of heavy metals on cognition is dependent on concentrations of and interactions between toxic and essential elements.
