Genomic characterization of a reemerging Chikungunya outbreak in Kedougou, Southeastern Senegal, 2023.

Chikungunya virus has caused millions of cases worldwide over the last twenty years, with recent outbreaks in Kedougou region in the southeastern Senegal, West Africa. Genomic characterization highlights that an ongoing epidemic in Kedougou in 2023 is not due to an introduction event but caused by the re-emergence of an endemic strain evolving linearly in a sylvatic context.

The Spatiotemporal Distribution and Molecular Characterization of Circulating Dengue Virus Serotypes/Genotypes in Senegal from 2019 to 2023.

Dengue virus is becoming a major public health threat worldwide, principally in Africa. From 2016 to 2020, 23 outbreaks were reported in Africa, principally in West Africa. In Senegal, dengue outbreaks have been reported yearly since 2017. Data about the circulating serotypes and their spatial and temporal distribution were limited to outbreaks that occurred between 2017 and 2018. Herein, we describe up-to-date molecular surveillance of circulating DENV serotypes in Senegal between 2019 to 2023 and their temporal and spatial distribution around the country. For this purpose, suspected DENV-positive samples were collected and subjected to dengue detection and serotyping using RT-qPCR methods. Positive samples were used for temporal and spatial mapping. A subset of DENV+ samples were then sequenced and subjected to phylogenetic analysis. Results show a co-circulation of three DENV serotypes with an overall predominance of DENV-3. In terms of abundance, DENV-3 is followed by DENV-1, with scarce cases of DENV-2 from February 2019 to February 2022. Interestingly, data show the extinction of both serotype 1 and serotype 2 and the only circulation of DENV-3 from March 2022 to February 2023. At the genotype level, the analysis shows that sequenced strains belong to same genotype as previously described: Senegalese DENV-1 strains belong to genotype V, DENV-2 strains to the cosmopolitan genotype, and DENV-3 strains to Genotype III. Interestingly, newly obtained DENV 1-3 sequences clustered in different clades within genotypes. This co-circulation of strains belonging to different clades could have an effect on virus epidemiology and transmission dynamics. Overall, our results highlight DENV serotype replacement by DENV-3, accompanied by a wider geographic distribution, in Senegal. These results highlight the importance of virus genomic surveillance and call for further viral fitness studies using both in vitro and in vivo models, as well as in-depth phylogeographic studies to uncover the virus dispersal patterns across the country.

Predictors of Death in Rifampicin Resistant Tuberculosis Patients Treated with the Short Course in Conakry, Guinea.

The emergence of rifampicin-resistant tuberculosis (RR-TB) is a major issue for TB control programs due to high risk of treatment failure and death. The objective of this study was to describe survival and to determine predictors of death in RR-TB patients treated with the short regimen (9-11 months) in the Conakry TB treatment centers. Sociodemographic, clinical, and survival data were collected prospectively between 2016 and 2021 on RR-TB patients in the Department of Pneumo-Phtisiology, the Carrière and the Tombolia TB centers. The Kaplan-Meier method was used to estimate the cumulative incidence of death of patients. The Cox regression model was used to identify the predictors independently associated with death. Of 869 patients, 164 (18.9%) patients died during treatment, 126 of them within 120 days of treatment initiation. The factors associated with death during treatment were as follows: patients treated in the Carrière TB center (adjusted hazard ratio [aHR] = 1.65; 95% CI: 1.06-2.59) and in the Department of Pneumo-Phtisiology (aHR = 3.26; 95% CI: 2.10-5.07), patients ≥ 55 years old (aHR = 4.80; 95% CI: 2.81-8.19), patients with no history of first-line TB treatment (aHR = 1.51; 95% CI: 1.05-2.16), and patients living with HIV (aHR = 2.81; 95% CI: 1.94-4.07). The results of this study can help the national TB control program to reconsider its therapeutic strategy to improve patient care in case of RR-TB. Large prospective clinical studies should be conducted to provide evidence of the impact of such factors like previous history of TB treatment and HIV infection on survival of RR-TB patients.

Assessment of lung injury severity using ultrasound in critically ill COVID-19 patients in resource limited settings.

BACKGROUND: Lung ultrasound is a non-invasive tool available at the bedside for the assessment of critically ill patients. The objective of this study was to evaluate the usefulness of lung ultrasound in assessing the severity of SARS-CoV-2 infection in critically-ill patients in a low-income setting. METHODS: We conducted a 12-month observational study in a university hospital intensive care unit (ICU) in Mali, on patients admitted for COVID-19 as diagnosed by a positive polymerase chain reaction for SARS-CoV-2 and/or typical lung computed tomography scan findings. RESULTS: The inclusion criteria was met by 156 patients with a median age of 59 years. Almost all patients (96%) had respiratory failure at admission and many needed respiratory support (121/156, 78%). The feasibility of lung ultrasound was very good, with 1802/1872 (96%) quadrants assessed. The reproducibility was good with an intra-class correlation coefficient of elementary patterns of 0.74 (95% CI 0.65, 0.82) and a coefficient of repeatability of lung ultrasound score < 3 for an overall score of 24. Confluent B lines were the most common lesions found in patients (155/156). The overall mean ultrasound score was 23 ± 5.4, and was significantly correlated with oxygen saturation (Pearson correlation coefficient of - 0.38, p < 0.001). More than half of the patients died (86/156, 55.1%). The factors associated with mortality, as shown by multivariable analysis, were: the patients' age; number of organ failures; therapeutic anticoagulation, and lung ultrasound score. CONCLUSION: Lung ultrasound was feasible and contributed to characterize lung injury in critically-ill COVID-19 patients in a low income setting. Lung ultrasound score was associated with oxygenation impairment and mortality.

Assessment of genotyping array performance for genome-wide association studies and imputation in African cattle.

BACKGROUND: In cattle, genome-wide association studies (GWAS) have largely focused on European or Asian breeds, using genotyping arrays that were primarily designed for European cattle. Because there is growing interest in performing GWAS in African breeds, we have assessed the performance of 23 commercial bovine genotyping arrays for capturing the diversity across African breeds and performing imputation. We used 409 whole-genome sequences (WGS) spanning global cattle breeds, and a real cohort of 2481 individuals (including African breeds) that were genotyped with the Illumina high-density (HD) array and the GeneSeek bovine 50 k array. RESULTS: We found that commercially available arrays were not effective in capturing variants that segregate among African indicine animals. Only 6% of these variants in high linkage disequilibrium (LD) (r2 > 0.8) were on the best performing arrays, which contrasts with the 17% and 25% in African and European taurine cattle, respectively. However, imputation from available HD arrays can successfully capture most variants (accuracies up to 0.93), mainly when using a global, not continent-specific, reference panel, which partially reflects the unusually high levels of admixture on the continent. When considering functional variants, the GGPF250 array performed best for tagging WGS variants and imputation. Finally, we show that imputation from low-density arrays can perform almost as well as HD arrays, if a two-stage imputation approach is adopted, i.e. first imputing to HD and then to WGS, which can potentially reduce the costs of GWAS. CONCLUSIONS: Our results show that the choice of an array should be based on a balance between the objective of the study and the breed/population considered, with the HD and BOS1 arrays being the best choice for both taurine and indicine breeds when performing GWAS, and the GGPF250 being preferable for fine-mapping studies. Moreover, our results suggest that there is no advantage to using the indicus-specific arrays for indicus breeds, regardless of the objective. Finally, we show that using a reference panel that better represents global bovine diversity improves imputation accuracy, particularly for non-European taurine populations.

Evaluating the Effectiveness of a Novel Systematic Screening Approach for Tuberculosis among Individuals Suspected or Recovered from COVID-19: Experiences from Niger and Guinea.

Evidence suggests that the COVID-19 pandemic negatively impacts tuberculosis (TB) activities. As TB and COVID-19 have similar symptoms, we assessed the effectiveness of integrated TB/COVID-19 screening in Guinea and Niger. From May to December 2020, TB screening was offered to symptomatic patients after a negative COVID-19 PCR test or after recovery from COVID-19 in Guinea. From December 2020 to March 2021, all presumptive COVID-19 patients with respiratory symptoms were tested simultaneously for COVID-19 and TB in Niger. We assessed the TB detection yield and used micro-costing to estimate the costs associated with both screening algorithms. A total of 863 individuals (758 in Guinea, and 105 in Niger), who were mostly male (60%) and with a median age of 34 (IQR: 26-45), were screened for TB. Reported symptoms were cough ≥2 weeks (49%), fever (45%), and weight loss (30%). Overall, 61 patients (7%) tested positive for COVID-19 (13 in Guinea, 48 in Niger) and 43 (4.9%) were diagnosed with TB disease (35 or 4.6% in Guinea, and 8 or 7.6% in Niger). The cost per person initiating TB treatment was USD $367 in Guinea and $566 in Niger. Overall, the yield of both approaches was high, and the cost was modest. Optimizing integrated COVID-19/TB screening may support maintaining TB detection during the ongoing pandemic.

Lessons learned for surveillance system strengthening through capacity building and partnership engagement in post-Ebola Guinea, 2015-2019.

The 2014-2016 Ebola outbreak in Guinea revealed systematic weaknesses in the existing disease surveillance system, which contributed to delayed detection, underreporting of cases, widespread transmission in Guinea and cross-border transmission to neighboring Sierra Leone and Liberia, leading to the largest Ebola epidemic ever recorded. Efforts to understand the epidemic's scale and distribution were hindered by problems with data completeness, accuracy, and reliability. In 2017, recognizing the importance and usefulness of surveillance data in making evidence-based decisions for the control of epidemic-prone diseases, the Guinean Ministry of Health (MoH) included surveillance strengthening as a priority activity in their post-Ebola transition plan and requested the support of partners to attain its objectives. The U.S. Centers for Disease Control and Prevention (US CDC) and four of its implementing partners-International Medical Corps, the International Organization for Migration, RTI International, and the World Health Organization-worked in collaboration with the Government of Guinea to strengthen the country's surveillance capacity, in alignment with the Global Health Security Agenda and International Health Regulations 2005 objectives for surveillance and reporting. This paper describes the main surveillance activities supported by US CDC and its partners between 2015 and 2019 and provides information on the strategies used and the impact of activities. It also discusses lessons learned for building sustainable capacity and infrastructure for disease surveillance and reporting in similar resource-limited settings.

Evaluation of the first two Frontline cohorts of the field epidemiology training program in Guinea, West Africa.

BACKGROUND: The 2014-2016 Ebola virus disease outbreak in West Africa revealed weaknesses in the health systems of the three most heavily affected countries, including a shortage of public health professionals at the local level trained in surveillance and outbreak investigation. In response, the Frontline Field Epidemiology Training Program (FETP) was created by CDC in 2015 as a 3-month, accelerated training program in field epidemiology that specifically targets the district level. In Guinea, the first two FETP-Frontline cohorts were held from January to May, and from June to September 2017. Here, we report the results of a cross-sectional evaluation of these first two cohorts of FETP-Frontline in Guinea. METHODS: The evaluation was conducted in April 2018 and consisted of interviews with graduates, their supervisors, and directors of nearby health facilities, as well as direct observation of data reports and surveillance tools at health facilities. Interviews and site visits were conducted using standardized questionnaires and checklists. Qualitative data were coded under common themes and analyzed using descriptive statistics. RESULTS: The evaluation revealed a significant perception of improvement in all assessed skills by the graduates, as well as high levels of self-reported involvement in key activities related to data collection, analysis, and reporting. Supervisors highlighted improvements to systematic and quality case and summary reporting as key benefits of the FETP-Frontline program. At the health facility level, staff reported the training had resulted in improvements to information sharing and case notifications. Reported barriers included lack of transportation, available support personnel, and other resources. Graduates and supervisors both emphasized the importance of continued and additional training to solidify and retain skills. CONCLUSIONS: The evaluation demonstrated a strongly positive perceived benefit of the FETP-Frontline training on the professional activities of graduates as well as the overall surveillance system. However, efforts are needed to ensure greater gender equity and to recruit more junior trainee candidates for future cohorts. Moreover, although improvements to the surveillance system were observed concurrent with the completion of the two cohorts, the evaluation was not designed to directly measure impact on surveillance or response functions. Combined with the rapid implementation of FETP-Frontline around the world, this suggests an opportunity to develop standardized evaluation toolkits, which could incorporate metrics that would directly assess the impact of equitable field epidemiology workforce development on countries' abilities to prevent, detect, and respond to public health threats.

First Malian series of surgery for rheumatic valve disease: opening of the centre, clinical features and peri-operative realities.

INTRODUCTION: Over the past two decades, the incidence of acute rheumatic fever (ARF) and chronic rheumatic heart disease (RHD) have dramatically declined in wealthier regions of the world as a result of preventative programmes, improved living standards and access to cardiac surgery. Nevertheless, ARF and RHD are still public health problems in less-developed regions of the world such as Oceania, south Asia and sub-Saharan Africa. AIM: We report on clinical, therapeutic and prognostic aspects as well as the difficulties encountered during this first series of surgery for rheumatic valve disease in Mali. METHODS: This was a prospective, descriptive study conducted at the Andre Festoc Cardiac Surgery Centre from September 2018 to August 2019. RESULTS: The frequency of patients having been operated on for rheumatic valve disease was 44.73% (68 patients). The mean age of the patients was 18 ± 10 years with extremes of five and 60 years. The gender ratio was 0.7. The delay to treatment was between one and three years for 39.7% of the patients. The main diagnoses found were: mitral regurgitation in 50% of patients, mitral stenosis in 16.2% and aortic regurgitation in 10.3%. Pulmonary artery systolic pressure was 35-50 mmHg in 19.1% of patients and more than 50 mmHg in 25%. The median cardiopulmonary bypass time was 132 minutes (60-276) and median extubation time was three hours (0-96). The main complications were cardiac, renal, neurological, respiratory, gastrointestinal and infectious. In the immediate postoperative period, we recorded three deaths, which is a mortality rate of 4.4%. CONCLUSIONS: Humanitarian efforts have led non-governmental organisations (NGOs) to launch surgical programmes in low-and middle-income countries in an attempt to fill the gap in these fragile healthcare systems. Cardiac surgery requires much expertise from the medical staff, as well as many material and financial resources. Empowerment of the local team is a challenge that is being realised since taking these essential steps of companionship with the NGO la Chaine de l'Espoir.

Evaluation of Early Warning, Alert and Response System for Ebola Virus Disease, Democratic Republic of the Congo, 2018-2020.

The 10th and largest Ebola virus disease epidemic in the Democratic Republic of the Congo (DRC) was declared in North Kivu Province in August 2018 and ended in June 2020. We describe and evaluate an Early Warning, Alert and Response System (EWARS) implemented in the Beni health zone of DRC during August 5, 2018-June 30, 2020. During this period, 194,768 alerts were received, of which 30,728 (15.8%) were validated as suspected cases. From these, 801 confirmed and 3 probable cases were detected. EWARS showed an overall good performance: sensitivity and specificity >80%, nearly all (97%) of alerts investigated within 2 hours of notification, and good demographic representativeness. The average cost of the system was US $438/case detected and US $1.8/alert received. The system was stable, despite occasional disruptions caused by political insecurity. Our results demonstrate that EWARS was a cost-effective component of the Ebola surveillance strategy in this setting.

Sorghum Grains Grading for Food, Feed, and Fuel Using NIR Spectroscopy.

Near-infrared spectroscopy (NIR) is a non-destructive, fast, and low-cost method to measure the grain quality of different cereals. However, the feasibility for determining the critical biochemicals, related to the classifications for food, feed, and fuel products are not adequately investigated. Fourier-transform (FT) NIR was applied in this study to determine the eight biochemicals in four types of sorghum samples: hulled grain flours, hull-less grain flours, whole grains, and grain flours. A total of 20 hybrids of sorghum grains were selected from the two locations in China. Followed by FT-NIR spectral and wet-chemically measured biochemical data, partial least squares regression (PLSR) was used to construct the prediction models. The results showed that sorghum grain morphology and sample format affected the prediction of biochemicals. Using NIR data of grain flours generally improved the prediction compared with the use of NIR data of whole grains. In addition, using the spectra of whole grains enabled comparable predictions, which are recommended when a non-destructive and rapid analysis is required. Compared with the hulled grain flours, hull-less grain flours allowed for improved predictions for tannin, cellulose, and hemicellulose using NIR data. This study aimed to provide a reference for the evaluation of sorghum grain biochemicals for food, feed, and fuel without destruction and complex chemical analysis.

"Assessing Today for a Better Tomorrow": An observational cohort study about quality of care, mortality and morbidity among newborn infants admitted to neonatal intensive care in Guinea.

BACKGROUND: Neonatal mortality in Guinea accounts for about 30% of all fatalities in children younger than five years. Countrywide, specialized neonatal intensive care is provided in one single clinic with markedly limited resources. To implement targeted measures, prospective data on patient characteristics and factors of neonatal death are needed. OBJECTIVE: To determine the rates of morbidity and mortality, to describe clinical characteristics of admitted newborns requiring intensive care, to assess the quality of disease management, and to identify factors contributing to neonatal mortality. METHODS: Prospective observational cohort study of newborns admitted to the hospital between mid-February and mid-March 2019 after birth in other institutions. Data were collected on maternal/prenatal history, delivery, and in-hospital care via convenience sampling. Associations of patient characteristics with in-hospital death were assessed using cause-specific Cox proportional-hazards models. RESULTS: Half of the 168 admitted newborns underwent postnatal cardiopulmonary resuscitation. Reasons for admission included respiratory distress (49.4%), poor postnatal adaptation (45.8%), prematurity (46.2%), and infections (37.1%). 101 newborns (61.2%) arrived in serious/critical general condition; 90 children (53.9%) showed clinical signs of neurological damage. Quality of care was poor: Only 59.4% of the 64 newborns admitted with hypothermia were externally heated; likewise, 57.1% of 45 jaundiced infants did not receive phototherapy. Death occurred in 56 children (33.3%) due to birth asphyxia (42.9%), prematurity (33.9%), and sepsis (12.5%). Newborns in serious/critical general condition at admission had about a fivefold higher hazard to die than those admitted in good condition (HR 5.21 95%-CI 2.42-11.25, p = <0.0001). Hypothermia at admission was also associated with a higher hazard of death (HR 2.00, 95%-CI 1.10-3.65, p = 0.023). CONCLUSION: Neonatal mortality was strikingly high. Birth asphyxia, prematurity, and infection accounted for 89.3% of death, aggravated by poor quality of in-hospital care. Children with serious general condition at admission had poor chances of survival. The whole concept of perinatal care in Guinea requires reconsideration.

Immunogenicity and safety of Ebola virus vaccines in healthy adults: a systematic review and network meta-analysis.

Clinical development of Ebola virus vaccines (EVV) was accelerated by the West African Ebola virus epidemic which remains the deadliest in history. To compare and rank the EVV according to their immunogenicity and safety. A total of 21 randomized controlled trial, evaluating seven different vaccines with different doses, and 5,275 participants were analyzed. The rVSVΔG-ZEBOV-GP (2 × 10 7) vaccine was more immunogenic (P-score 0.80). For pain, rVSVΔG-ZEBOV-GP (≤10 5) had few events (P-score 0.90). For fatigue and headache, the DNA-EBOV (≤ 4 mg) was the best one with P-scores of 0.94 and 0.87, respectively. For myalgia, the ChAd3 (10 10) had a lower risk (P-score 0.94). For fever, the Ad5.ZEBOV (≤ 8 × 10 10) was the best one (P-score 0.80). The best vaccine to be used to stop future outbreak of Ebola is the rVSVDG-ZEBOV-GP vaccine at dose of 2 × 107 PFU.

Malnutrition prevalence and associated biochemical factors among drug-resistance tuberculosis (DR-TB) patients at key treatment sites in Conakry City, Republic of Guinea.

INTRODUCTION: drug-resistant tuberculosis is a major global health problem and a threat to health security given the increase in the number of cases and the challenges associated with care. Besides, the relationship between poor nutritional status and tuberculosis is clearly established. For relevant and evidence-based public health decision-making regarding the management of malnutrition in patients with drug-resistant tuberculosis in the initial phase, it is essential to estimate the prevalence of malnutrition and understand the risk factors associated with it. METHODS: we performed a retrospective cohort study in drug-resistant tuberculosis patients aged 18 years and older, among which the nutritional status was assessed through BMI. All predictors were included in a prediction model using the multivariate logistic model according to the lowest Akaike criterion. Discrimination and model calibration was evaluated using receiver performance analysis, and the Hosmer and Lemeshow test. RESULTS: this study revealed a prevalence of malnutrition of 64.7% in drug-resistant tuberculosis patients in our 218-patient series. The factors associated with malnutrition were: unsuccessful treatment, the active presence of mycobacterium tuberculosis, increased bacteriological conversion time, increased serum creatinine, increased transaminase SGPT of the liver, and anaemia. Some of the factors not associated with malnutrition included the history of anti-tuberculosis treatment, vomiting, hepatic SGPT, initial AFB count, smear and culture conversion time, depression, and chest X-ray. CONCLUSION: malnutrition remains a concern among drug-resistant tuberculosis patients in Guinea as it affects more than half of them with a negative impact on the outcome of treatment. Implementing specific interventions for these high-risk patients, including nutritional supplementation, psychosocial support, and treatment for tuberculosis, can improve management for better treatment outcomes.

Ebola Virus Transmission Initiated by Relapse of Systemic Ebola Virus Disease.

During the 2018-2020 Ebola virus disease (EVD) outbreak in North Kivu province in the Democratic Republic of Congo, EVD was diagnosed in a patient who had received the recombinant vesicular stomatitis virus-based vaccine expressing a ZEBOV glycoprotein (rVSV-ZEBOV) (Merck). His treatment included an Ebola virus (EBOV)-specific monoclonal antibody (mAb114), and he recovered within 14 days. However, 6 months later, he presented again with severe EVD-like illness and EBOV viremia, and he died. We initiated epidemiologic and genomic investigations that showed that the patient had had a relapse of acute EVD that led to a transmission chain resulting in 91 cases across six health zones over 4 months.

El nivel de accesibilidad se midió con el sistema de información geográfica, evaluando la proporción de habitantes por distritos y su recorrido en intervalos, desde 1 km hasta más de 4 km, se asumió 2 km como distancia máxima permisible en transporte público. Resultados: El distrito con la mayor prioridad correspondió a Ratoma, seguido de Matoto, Kaloum, Matam y Dixinn, en este mismo orden Conclusiones: La priorización de distritos en Conakry, según necesidades de atención primaria, puede apoyar al gobierno en la toma de decisiones para la implementación de políticas de salud que permitan avanzar hacia su cobertura universal(AU)

Introduction: Low accessibility to primary care services in Conakry affects the health of its population. The health sector, in view of the financial constraints, aims to prioritize the progressive extension of coverage of primary care facilities, as a first step towards universal health coverage. Objective: Prioritize the five districts of Conakry city, in the Republic of Guinea, for the progressive extension of primary care facilities´ coverage. Methods: A priority was established for each district based on the logical-deductive analysis of two variables: health level and accessibility level to primary care facilities. The health level was defined according to two criteria: socio-demographic vulnerability and morbidity and mortality level, with the combination of geographic information systems with multicriteria assessment. The level of accessibility was measured with the geographic information system, assessing the proportion of inhabitants by district and their route at intervals, from 1km to more than 4km; it was assumed 2km as the maximum permissible distance by public transport. Results: The district with the highest priority was Ratoma, followed by Matoto, Kaloum, Matam and Dixinn, in this same order. Conclusions: Prioritization of districts in Conakry city, according to primary care needs, can support the government in making decisions for the implementation of health policies that allow progress towards universal health coverage(AU)

Implementation of DHIS2 for Disease Surveillance in Guinea: 2015-2020.

A robust epidemic-prone disease surveillance system is a critical component of public health infrastructure and supports compliance with the International Health Regulations (IHR). One digital health platform that has been implemented in numerous low- and middle-income countries is the District Health Information System Version 2 (DHIS2). In 2015, in the wake of the Ebola epidemic, the Ministry of Health in Guinea established a strategic plan to strengthen its surveillance system, including adoption of DHIS2 as a health information system that could also capture surveillance data. In 2017, the DHIS2 platform for disease surveillance was piloted in two regions, with the aim of ensuring the timely availability of quality surveillance data for better prevention, detection, and response to epidemic-prone diseases. The success of the pilot prompted the national roll-out of DHIS2 for weekly aggregate disease surveillance starting in January 2018. In 2019, the country started to also use the DHIS2 Tracker to capture individual cases of epidemic-prone diseases. As of February 2020, for aggregate data, the national average timeliness of reporting was 72.2%, and average completeness 98.5%; however, the proportion of individual case reports filed was overall low and varied widely between diseases. While substantial progress has been made in implementation of DHIS2 in Guinea for use in surveillance of epidemic-prone diseases, much remains to be done to ensure long-term sustainability of the system. This paper describes the implementation and outcomes of DHIS2 as a digital health platform for disease surveillance in Guinea between 2015 and early 2020, highlighting lessons learned and recommendations related to the processes of planning and adoption, pilot testing in two regions, and scale up to national level.

The first 2 h after birth: prevalence and factors associated with neonatal care practices from a multicountry, facility-based, observational study.

BACKGROUND: Amid efforts to improve the quality of care for women and neonates during childbirth, there is growing interest in the experience of care, including respectful care practices. However, there is little research on the prevalence of practices that might constitute mistreatment of neonates. This study aims to describe the care received by neonates up to 2 h after birth in a sample of three countries in west Africa. METHODS: Data from this multicountry, facility-based, observational study were collected on 15 neonatal care practices across nine facilities in Ghana, Guinea, and Nigeria, as part of WHO's wider multicountry study on how women are treated during childbirth. Women were eligible if they were admitted to the participating health facilities for childbirth, in early established labour or active labour, aged 15 years or older, and provided written informed consent on behalf of themselves and their neonate. All labour observations were continuous, one-to-one observations of women and neonates by independent data collectors. Descriptive statistics and multivariate logistic regressions were used to examine associations between these neonatal care practices, maternal and neonate characteristics, and maternal mistreatment. Early neonate deaths, stillbirths, and higher order multiple births were excluded from analysis. FINDINGS: Data collection took place from Sept 19, 2016, to Feb 26, 2017, in Nigeria; from Aug 1, 2017, to Jan 18, 2018, in Ghana; and from July 1 to Oct 30, 2017, in Guinea. We included data for 362 women-neonate dyads (356 [98%] with available data for neonatal care practices) in Nigeria, 760 (749 [99%]) in Ghana, and 558 (522 [94%]) in Guinea. Delayed cord clamping was done for most neonates (1493 [91·8%] of 1627); other practices, such as skin-to-skin contact, were less commonly done (1048 [64·4%]). During the first 2 h after birth, separation of the mother and neonate occurred in 844 (51·9%) of 1627 cases; and was more common for mothers who were single (adjusted odds ratio [AOR; adjusting for country, maternal age, education, marital status, neonate weight at birth, and neonate sex] 1·8, 95% CI 1·3-2·6) than those who were married or cohabiting. Lack of maternal education was associated with increased likelihood of neonates not receiving recommended breastfeeding practices. Neonates with a low birthweight (<2·5 kg) were more likely (1·7, 1·1-2·8) to not begin breastfeeding on demand than full weight neonates. When women experienced physical abuse from providers within 1 h before childbirth, their neonates were more likely to be slapped (AOR 1·9, 1·1-3·9). INTERPRETATION: A high proportion of neonates did not receive recommended care practices, and some received practices that might constitute mistreatment. Further research is needed on understanding and measuring mistreatment to improve care, including respectful care, for mothers and neonates.

Labour companionship and women's experiences of mistreatment during childbirth: results from a multi-country community-based survey.

BACKGROUND: Evidence has shown the benefits of labour companions during childbirth. Few studies have documented the relationship between the absence of labour companions and mistreatment of women during childbirth in low-income and middle-income countries using a standardised tool. METHODS: We conducted a secondary analysis of the WHO multi-country study on how women are treated during childbirth, where a cross-sectional community survey was conducted with women up to 8 weeks after childbirth in Ghana, Guinea, Nigeria and Myanmar. Descriptive analysis and multivariable logistic regression were used to examine whether labour companionship was associated with various types of mistreatment. RESULTS: Of 2672 women, about half (50.4%) reported the presence of a labour companion. Approximately half (49.6%) of these women reported that the timing of support was during labour and after childbirth and most of the labour companions (47.0%) were their family members. Across Ghana, Guinea and Nigeria, women without a labour companion were more likely to report physical abuse, non-consented medical procedures and poor communication compared with women with a labour companion. However, there were country-level variations. In Guinea, the absence of labour companionship was associated with any physical abuse, verbal abuse, or stigma or discrimination (adjusted OR (AOR) 3.6, 1.9-6.9) and non-consented vaginal examinations (AOR 3.2, 1.6-6.4). In Ghana, it was associated with non-consented vaginal examinations (AOR 2.3, 1.7-3.1) and poor communication (AOR 2.0, 1.3-3.2). In Nigeria, it was associated with longer wait times (AOR 0.6, 0.3-0.9). CONCLUSION: Labour companionship is associated with lower levels of some forms of mistreatment that women experience during childbirth, depending on the setting. Further work is needed to ascertain how best to implement context-specific labour companionship to ensure benefits while maintaining women's choices and autonomy.
