RESUMO

BACKGROUND: Severe bacterial infections (SBIs) are a leading cause of neonatal deaths in low- and middle-income countries (LMICs). However, most data came from hospitals, which do not include neonates who did not seek care or were treated outside the hospital. Studies from the community are scarce, and few among those available were conducted with high-quality microbiological techniques. The burden of SBI at the community level is therefore largely unknown. We aimed here to describe the incidence, etiology, risk factors, and antibiotic resistance profiles of community-acquired neonatal SBI in 3 LMICs. METHODS AND FINDINGS: The BIRDY study is a prospective multicentric community-based mother and child cohort study and was conducted in both urban and rural areas in Madagascar (2012 to 2018), Cambodia (2014 to 2018), and Senegal (2014 to 2018). All pregnant women within a geographically defined population were identified and enrolled. Their neonates were actively followed from birth to 28 days to document all episodes of SBI. A total of 3,858 pregnant women (2,273 (58.9%) in Madagascar, 814 (21.1%) in Cambodia, and 771 (20.0%) in Senegal) were enrolled in the study, and, of these, 31.2% were primigravidae. Women enrolled in the urban sites represented 39.6% (900/2,273), 45.5% (370/814), and 61.9% (477/771), and those enrolled in the rural sites represented 60.4% (1,373/2,273), 54.5% (444/814), and 38.1% (294/771) of the total in Madagascar, Cambodia, and Senegal, respectively. Among the 3,688 recruited newborns, 49.6% were male and 8.7% were low birth weight (LBW). The incidence of possible severe bacterial infection (pSBI; clinical diagnosis based on WHO guidelines of the Integrated Management of Childhood Illness) was 196.3 [95% confidence interval (CI) 176.5 to 218.2], 110.1 [88.3 to 137.3], and 78.3 [59.5 to 103] per 1,000 live births in Madagascar, Cambodia, and Senegal, respectively. The incidence of pSBI differed between urban and rural sites in all study countries. In Madagascar, we estimated an incidence of 161.0 pSBI per 1,000 live births [133.5 to 194] in the urban site and 219.0 [192.6 to 249.1] pSBI per 1,000 live births in the rural site (p = 0.008). In Cambodia, estimated incidences were 141.1 [105.4 to 189.0] and 85.3 [61.0 to 119.4] pSBI per 1,000 live births in urban and rural sites, respectively (p = 0.025), while in Senegal, we estimated 103.6 [76.0 to 141.2] pSBI and 41.5 [23.0 to 75.0] pSBI per 1,000 live births in urban and rural sites, respectively (p = 0.006). The incidences of culture-confirmed SBI were 15.2 [10.6 to 21.8], 6.5 [2.7 to 15.6], and 10.2 [4.8 to 21.3] per 1,000 live births in Madagascar, Cambodia, and Senegal, respectively, with no difference between urban and rural sites in each country. The great majority of early-onset infections occurred during the first 3 days of life (72.7%). The 3 main pathogens isolated were Klebsiella spp. (11/45, 24.4%), Escherichia coli (10/45, 22.2%), and Staphylococcus spp. (11/45, 24.4%). Among the 13 gram-positive isolates, 5 were resistant to gentamicin, and, among the 29 gram-negative isolates, 13 were resistant to gentamicin, with only 1 E. coli out of 10 sensitive to ampicillin. Almost one-third of the isolates were resistant to both first-line drugs recommended for the management of neonatal sepsis (ampicillin and gentamicin). Overall, 38 deaths occurred among neonates with SBI (possible and culture-confirmed SBI together). LBW and foul-smelling amniotic fluid at delivery were common risk factors for early pSBI in all 3 countries. A main limitation of the study was the lack of samples from a significant proportion of infants with pBSI including 35 neonatal deaths. Without these samples, bacterial infection and resistance profiles could not be confirmed. CONCLUSIONS: In this study, we observed a high incidence of neonatal SBI, particularly in the first 3 days of life, in the community of 3 LMICs. The current treatment for the management of neonatal infection is hindered by antimicrobial resistance. Our findings suggest that microbiological diagnosis of SBI remains a challenge in these settings and support more research on causes of neonatal death and the implementation of early interventions (e.g., follow-up of at-risk newborns during the first days of life) to decrease the burden of neonatal SBI and associated mortality and help achieve Sustainable Development Goal 3.

RESUMO

BACKGROUND: We describe an on-site clinical mentoring program aimed at improving emergency obstetrical and new-born care (EmONC) in Nepal and assess its effectiveness on nurses' knowledge and skills. In Nepal, both the maternal mortality ratio (MMR, 239/100,000 live births) and the neonatal mortality rate (NMR, 21/1000 live births) were among the highest in the world in 2016, despite impressive progress over recent decades considering the challenging environment. METHODS: From September 2016 to April 2018, three experienced nurses conducted repeated mentoring visits in 61 comprehensive or basic EmONC centers and birthing centers located in 4 provinces of Nepal. Using updated national training manuals and teaching aids, these clinical mentors assessed and taught 12 core EmONC clinical skills to their nurse-mentees. Clinical mentors worked with management mentors whose goal was to improve the nurses' working environment. We assessed whether the cohort of nurse-mentees performed better as a group and individually performed better at the end of the program than at baseline using relevant tests (chi-square test, Wilcoxon matched-pairs signed-rank test, and Kruskal-Wallis equality-of-population rank test). RESULTS: In total, 308 nurses were assessed, including 96 (31.2%), 77 (25.0%) and 135 (43.8%) who participated in all three, two or only one mentoring session, respectively. In total, 225 (73.0%) worked as auxiliary nurse-midwives (ANMs), while 69 (22.4%) worked as nurses. One hundred and ninety five (63.3%) were trained as skilled birth attendants, of which 45 (23.1%) were nurses, 141 (72.3%) were auxiliaries and 9 (4.6%) had other positions. The proportion of ANMs and nurse-mentees who obtained a knowledge assessment score ≥ 85% increased from 57.8 to 86.1% (p <  0.001). Clinical assessment scores increased significantly for each participant, and therefore for the group. SBA-trained mentees had better knowledge of maternal and new-born care and were better able to perform the 12 core clinical skills throughout the program. CONCLUSIONS: Our study suggests that on-site clinical mentoring of nurses coupled with health facility management mentoring can improve nurses' clinical competences in and performance of maternity and new-born care. Assessing evidence of impact on patient safety would be the next stage in evaluating this promising intervention.

RESUMO

Severe bacterial infections are a leading cause of death among neonates in low-income countries, which harbor several factors leading to emergence and spread of multidrug-resistant bacteria. Low-income countries should prioritize interventions to decrease neonatal infections; however, data are scarce, specifically from the community. To assess incidence, etiologies, and antimicrobial drug-resistance patterns of neonatal infections, during 2012-2014, we conducted a community-based prospective investigation of 981 newborns in rural and urban areas of Madagascar. The incidence of culture-confirmed severe neonatal infections was high: 17.7 cases/1,000 live births. Most (75%) occurred during the first week of life. The most common (81%) bacteria isolated were gram-negative. The incidence rate for multidrug-resistant neonatal infection was 7.7 cases/1,000 live births. In Madagascar, interventions to improve prevention, early diagnosis, and management of bacterial infections in neonates should be prioritized.

RESUMO

PROBLEM: Seven months after the April 2015 Nepal earthquake, and as relief efforts were scaling down, health authorities faced ongoing challenges in health-service provision and disease surveillance reporting. APPROACH: In January 2016, the World Health Organization recruited and trained 12 Nepalese medical doctors to provide technical assistance to the health authorities in the most affected districts by the earthquake. These emergency support officers monitored the recovery of health services and reconstruction of health facilities, monitored stocks of essential medicines, facilitated disease surveillance reporting to the health ministry and assisted in outbreak investigations. LOCAL SETTING: In December 2015 the people most affected by the earthquake were still living in temporary shelters, provision of health services was limited and only five out of 14 earthquake-affected districts were reporting surveillance data to the health ministry. RELEVANT CHANGES: From mid-2016, health facilities were gradually able to provide the same level of services as in unaffected areas, including paediatric and adolescent services, follow-up of tuberculosis patients, management of respiratory infections and first aid. The number of districts reporting surveillance data to the health ministry increased to 13 out of 14. The proportion of health facilities reporting medicine stock-outs decreased over 2016. Verifying rumours of disease outbreaks with field-level evidence, and early detection and containment of outbreaks, allowed district health authorities to focus on recovery and reconstruction. LESSONS LEARNT: Local medical doctors with suitable experience and training can augment the disaster recovery efforts of health authorities and alleviate their burden of work in managing public health challenges during the recovery phase.

RESUMO

This case study describes the health response provided by the Ministry of Health of Nepal with support from UN agencies and several other organisations, to the 1.4 million women and adolescent girls affected by the major earthquake that struck Nepal in April 2015. After a post-disaster needs assessment, the response was provided to cater for the identified sexual and reproductive health (RH) needs, following the guidance of the Minimum Initial Service Package for RH developed by the global Inter-Agency Working Group. We describe the initiatives implemented to resume RH services: the distribution of medical camp kits, the deployment of nurses with birth attendance skills, the organisation of outreach RH camps, the provision of emergency RH kits and midwifery kits to health facilities and the psychosocial counselling support provided to maternity health workers. We also describe how shelter and transition homes were established for pregnant and post-partum mothers and their newborns, the distribution of dignity kits, of motivational kits for affected women and girls and female community health volunteers. We report on the establishment of female-friendly spaces near health facilities to offer a multisectoral response to gender-based violence, the setting up of adolescent-friendly service corners in outreach RH camps, the development of a menstrual health and hygiene management programme and the linkages established between adolescent-friendly information corners of schools and adolescent-friendly service centres in health facilities. Finally, we outline the gaps, challenges and lessons learned and suggest recommendations for preparedness and response interventions for future disasters.

RESUMO

BACKGROUND: The diagnosis of tuberculosis in human immunodeficiency virus (HIV)-infected children is challenging. We assessed the performance of alternative specimen collection methods for tuberculosis diagnosis in HIV-infected children using Xpert MTB/RIF (Xpert). METHODS: HIV-infected children aged ≤13 years with suspected intrathoracic tuberculosis were enrolled in 8 hospitals in Burkina Faso, Cambodia, Cameroon, and Vietnam. Gastric aspirates were taken for children aged <10 years and expectorated sputum samples were taken for children aged ≥10 years (standard samples); nasopharyngeal aspirate and stool were taken for all children, and a string test was performed if the child was aged ≥4 years (alternative samples). All samples were tested with Xpert. The diagnostic accuracy of Xpert for culture-confirmed tuberculosis was analyzed in intention-to-diagnose and per-protocol approaches. RESULTS: Of 281 children enrolled, 272 (96.8%) had ≥1 specimen tested with Xpert (intention-to-diagnose population), and 179 (63.5%) had all samples tested with Xpert (per-protocol population). Tuberculosis was culture-confirmed in 29/272 (10.7%) children. Intention-to-diagnose sensitivities of Xpert performed on all, standard, and alternative samples were 79.3% (95% confidence interval [CI], 60.3-92.0), 72.4% (95% CI, 52.8-87.3), and 75.9% (95% CI, 56.5-89.7), respectively. Specificities were ≥97.5%. Xpert combined on nasopharyngeal aspirate and stool had intention-to-diagnose and per-protocol sensitivities of 75.9% (95% CI, 56.5-89.7) and 75.0% (95% CI, 47.6-92.7), respectively. CONCLUSIONS: The combination of nasopharyngeal aspirate and stool sample is a promising alternative to methods usually recommended by national programs. Xpert performed on respiratory and stools samples enables rapid confirmation of tuberculosis diagnosis in HIV-infected children. CLINICAL TRIALS REGISTRATION: The ANRS (Agence Nationale de Recherche sur le Sida) 12229 PAANTHER (Pediatric Asian African Network for Tuberculosis and HIV Research) 01 study is registered at ClinicalTrials.gov (NCT01331811).

RESUMO

C-sections are an increasingly performed medical practice which can save lives but may also lead to major complications. Through a mixed methods study conducted in 2015 in Cambodia, we aimed to analyze the reasons for requesting a c-section and to explore factors that are associated with c-sections. 60% of the women in the cohort who gave birth by c-section reported having requested it. Through 31 in-depth interviews, we determined the reasons given by women for requesting a c-section before and during labour. Before labour, reasons for requesting a c-section were: choosing the delivery date; bringing luck and joy to the family; protecting the genitals, and the belief that c-section is safer for the mother and for the baby. Reasons given during labour were fear, pain, and having no more energy. We also observed two major factors driving the women's request for a c-section: family support for requesting a c-section, and the over-usage of ultrasound examinations. Our multivariate analysis of the interviews of 143 women before and after delivery showed that having a previous c-section, delivering in a private facility, being older than median at the time of sexual debut, residing outside of Phnom Penh and having the delivery costs covered by the family were all factors independently and significantly associated with a higher chance of c-section delivery. We conclude that women are not well informed to give consent for c-delivery, and that their request is often affected by false belief and poor knowledge.

RESUMO

First documented in 1741, the practice of episiotomy substantially increased worldwide during the 20th century. However, research shows that episiotomy is not effective in reducing severe perineal trauma and may be harmful. Using a mixed-methods approach, we conducted a study in 2013-14 on why obstetricians and midwives in a large maternity hospital in Phnom Penh, Cambodia, still do routine episiotomies. The study included the extent of the practice, based on medical records; a retrospective analysis of the delivery notes of a random sample of 365 patients; and 22 in-depth interviews with obstetricians, midwives and recently delivered women. Of the 365 women, 345 (94.5%, 95% CI: 91.7-96.6) had had an episiotomy. Univariate analysis showed that nulliparous women underwent episiotomy more frequently than multiparous women (OR 7.1, 95% CI 2.0-24.7). The reasons given for this practice by midwives and obstetricians were: fear of perineal tears, the strong belief that Asian women have a shorter and harder perineum than others, lack of time in overcrowded delivery rooms, and the belief that Cambodian women would be able to have a tighter and prettier vagina through this practice. A restrictive episiotomy policy and information for pregnant women about birthing practices through antenatal classes should be implemented as soon as possible.

RESUMO

In 2009, we conducted a case-control study to explore the routes of HCV transmission in people living with HIV/AIDS (PLHIV) in Cambodia. Cases were HCV/HIV co-infected patients (who tested RT-PCR positive for HCV-RNA or had confirmed presence of HCV antibodies) (n = 44). Controls were HIV mono-infected patients, with no HCV antibodies (n = 160). They were recruited among the PLHIV presenting at one national reference centre of HIV/AIDS. Multivariate analysis showed that factors associated with the co-infection were the age older than 50 years (OR 5.4, 95 % confidence interval (CI) 1.5-19.6), the exposure to multiple parenteral infusions before the year 2000 (OR 3.4, 95 % CI 1.5-7.6), to surgery (OR 2.6, 95 % CI 1.2-5.7) and to fibroscopy (OR 2.4, 95 % CI 1.0-5.7). These results show the need to implement HCV screening in PLHIV, to support the implementation of national infection control guidelines, and to reinforce public awareness on the risks linked to parenteral medications.

RESUMO

BACKGROUND: Dengue is a major contributor to morbidity in children aged twelve and below throughout Cambodia; the 2012 epidemic season was the most severe in the country since 2007, with more than 42,000 reported (suspect or confirmed) cases. METHODS: We report basic epidemiological characteristics in a series of 701 patients at the National Paediatric Hospital in Cambodia, recruited during a prospective clinical study (2011-2012). To more fully explore this cohort, we examined climatic factors using multivariate negative binomial models and spatial clustering of cases using spatial scan statistics to place the clinical study within a larger epidemiological framework. RESULTS: We identify statistically significant spatial clusters at the urban village scale, and find that the key climatic predictors of increasing cases are weekly minimum temperature, median relative humidity, but find a negative association with rainfall maximum, all at lag times of 1-6 weeks, with significant effects extending to 10 weeks. CONCLUSIONS: Our results identify clustering of infections at the neighbourhood scale, suggesting points for targeted interventions, and we find that the complex interactions of vectors and climatic conditions in this setting may be best captured by rising minimum temperature, and median (as opposed to mean) relative humidity, with complex and limited effects from rainfall. These results suggest that real-time cluster detection during epidemics should be considered in Cambodia, and that improvements in weather data reporting could benefit national control programs by allow greater prioritization of limited health resources to both vulnerable populations and time periods of greatest risk. Finally, these results add to the increasing body of knowledge suggesting complex interactions between climate and dengue cases that require further targeted research.

RESUMO

BACKGROUND: Few data exist on viral and bacterial etiology of acute lower respiratory infections (ALRI) in ≥ 5 year -old persons in the tropics. METHODS: We conducted active surveillance of community-acquired ALRI in two hospitals in Cambodia, a low-income tropical country. Patients were tested for acid-fast bacilli (AFB) by direct sputum examination, other bacteria by blood and/or sputum cultures, and respiratory viruses using molecular techniques on nasopharyngeal/throat swabs. Pulmonologists reviewed clinical/laboratory data and interpreted chest X-rays (CXR) to confirm ALRI. RESULTS: Between April 2007 - December 2009, 1,904 patients aged ≥5 years were admitted with acute pneumonia (50.4%), lung sequelae-associated ALRI (24.3%), isolated pleural effusions (8.9%) or normal CXR-related ALRI (17.1%); 61 (3.2%) died during hospitalization. The two former diagnoses were predominantly due to bacterial etiologies while viral detection was more frequent in the two latter diagnoses. AFB-positive accounted for 25.6% of acute pneumonia. Of the positive cultures (16.8%), abscess-prone Gram-negative bacteria (39.6%) and Haemophilus influenzae (38.0%) were most frequent, followed by Streptococcus pneumoniae (17.7%). Of the identified viruses, the three most common viruses included rhinoviruses (49.5%), respiratory syncytial virus (17.7%) and influenza viruses (12.1%) regardless of the diagnostic groups. Wheezing was associated with viral identification (31.9% vs. 13.8%, p < 0.001) independent of age and time-to-admission. CONCLUSIONS: High frequency of H. influenzae and S. pneumoniae infections support the need for introduction of the respective vaccines in the national immunization program. Tuberculosis was frequent in patients with acute pneumonia, requiring further investigation. The relationship between respiratory viruses and wheezing merits further studies.

RESUMO

In Cambodia, traditional medicine was commonly described as being used by pregnant women at two time points: one month before birth and during early postpartum. The present study aims to describe traditional medicine consumption during postpartum phase for women enrolled in the TA PROHM study and to investigate the possible association between traditional medicine consumption and acute liver toxicity. An ethnobotanical survey was conducted in 2 groups of HBV-infected pregnant women (with and without postpartum hepatocellular injury) enrolled in the study. Hepatocellular injury was defined by having Alanine Aminotransferase (ALT) > 2.5 times the Upper Limit of Normal (ULN = 40 U/L) at the 6th week postpartum visit. Interviews were done using a standardized questionnaire. Plant samples were collected and later identified by two traditional healers. Chi-square test was used to find the association between hepatocellular injury and traditional medicine consumption or a specific plant species. In total, 75 women were enrolled and 52 (69.3%) used at least one traditional remedy composed of 123 different plants and 12 alcoholic macerations of porcupine stomach. Orally consuming at least one remedy with alcohol was significantly associated with hepatocellular injury (33% vs 13%, p = 0.034). Among the 123 plants species identified, four were found to be associated with hepatocellular injury, namely Amphineurion marginatum (Roxb.) D.J.Middleton [Apocynaceae] (p = 0.022), Selaginella tamariscina (P.Beauv.) Spring [Selaginellaceae] (p = 0.048), Mitragyna speciosa Korth. [Rubiaceae] (p = 0.099) and Tetracera indica (Christm. & Panz.) Merr. [Dilleniaceae] (p = 0.079). Consumption of traditional medicine in postpartum is a common practice for women enrolled in the TA PROHM study. Alcohol-based remedies may exacerbate the risk of acute hepatocellular injury in HBV-infected women already exposed to immune restoration. The complex mixtures of herbs need to be further evaluated by in vitro and in vivo studies.

RESUMO

BACKGROUND: In many Asian countries, Klebsiella pneumoniae (KP) is the second pathogen responsible for community-acquired pneumonia. Yet, very little is known about KP etiology in ALRI in Cambodia, a country that has one of the weakest medical infrastructures in the region. We present here the first clinico-radiological description of KP community-acquired ALRI in hospitalized Cambodian patients. METHODS: Through ALRI surveillance in two provincial hospitals, KP was isolated from sputum and blood cultures, and identified by API20E gallery from patients ≥ 5 years-old with fever and respiratory symptoms onset ≤14 days. Antibiotics susceptibility testing was provided systematically to clinicians when bacteria were isolated. We collected patients' clinical, radiological and microbiological data and their outcome 3 months after discharge. We also compared KP-related with other bacteria-related ALRI to determine risk factors for KP infection. RESULTS: From April 2007 to December 2009, 2315 ALRI patients ≥ 5 years-old were enrolled including 587 whose bacterial etiology could be assigned. Of these, 47 (8.0%) had KP infection; their median age was 55 years and 68.1% were females. Reported prior medication was high (42.5%). Patients' chest radiographs showed pneumonia (61.3% including 39% that were necrotizing), preexisting parenchyma lesions (29.5%) and pleural effusions alone (4.5%) and normal parenchyma (4.5%). Five patients had severe conditions on admission and one patient died during hospitalization. Of the 39 patients that were hospital discharged, 14 died including 12 within 1 month after discharge. Only 13 patients (28%) received an appropriate antibiotherapy. Extended-spectrum beta-lactamases (ESBL) - producing strains were found in 8 (17.0%) patients. Female gender (Odds ratio (OR) 2.1; p = 0.04) and diabetes mellitus (OR 3.1; p = 0.03) were independent risk factors for KP-related ALRI. CONCLUSIONS: KP ALRI in Cambodia has high fatality rate, are more frequently found in women, and should be considered in diabetic patients. The extremely high frequency of ESBL-producing strains in the study is alarming in the context of uncontrolled antibiotic consumption and in absence of microbiology capacity in most public-sector hospitals.

RESUMO

BACKGROUND: There is no gold standard for tuberculosis diagnosis in children. Clinical Case Definitions for Classification of Intrathoracic Tuberculosis in Children were proposed by international experts in 2012 and updated in 2015. We aimed to compare the 2012 and 2015 Clinical Case Definitions in HIV-infected children with suspected tuberculosis. METHODS: We enrolled HIV-infected children with suspected tuberculosis in Burkina Faso, Cambodia, Cameroon, and Vietnam (ANRS [Agence Nationale de Recherches sur le SIDA et les hépatites virales] 12229 PAANTHER [Pediatric Asian African Network for Tuberculosis and HIV Research] 01 Study). We classified children using the 2012 and 2015 Case Definitions considering as tuberculosis cases those with confirmed tuberculosis and those with probable and unconfirmed tuberculosis in the 2012 and the 2015 classifications, respectively. We assessed agreement between both classifications. RESULTS: Of 438 children enrolled, 197 (45.0%) children were classified as tuberculosis (45 confirmed, 152 probable) using the 2012 Case Definition and 251 (57.3%) were classified as tuberculosis (55 confirmed, 196 unconfirmed) using the 2015 classification. Inter-classification agreement for tuberculosis diagnosis was 364/438, 83.1%, with a kappa statistic of 0.667 (95% confidence interval 0.598-0.736). Of 152 children with probable tuberculosis (2012), 142 (93.4%) were considered as tuberculosis by the 2015 version and 10 (6.6%) as unlikely tuberculosis including 9 with spontaneous clinical improvement. Of 132 possible tuberculosis (2012), 58 (43.9%) were reclassified as tuberculosis (2015). CONCLUSIONS: Agreement between the 2 versions of the Case Definition was substantial but more children were considered as tuberculosis using the 2015 version. Spontaneous symptom resolution reinforces both confidence in the "unlikely" category as being children without tuberculosis and the importance of the clinician's treatment decision in the study.

RESUMO

BACKGROUND: Melioidosis is a disease caused by Burkholderia pseudomallei and considered endemic in South-East Asia but remains poorly documented in Cambodia. We report the first series of hospitalized pulmonary melioidosis cases identified in Cambodia describing clinical characteristics and outcomes. METHODS: We characterized cases of acute lower respiratory infections (ALRI) that were identified through surveillance in two provincial hospitals. Severity was defined by systolic blood pressure, cardiac frequency, respiratory rate, oxygen saturation and body temperature. B. pseudomallei was detected in sputum or blood cultures and confirmed by API20NE gallery. We followed up these cases between 6 months and 2 years after hospital discharge to assess the cost-of-illness and long-term outcome. RESULTS: During April 2007 - January 2010, 39 ALRI cases had melioidosis, of which three aged ≤2 years; the median age was 46 years and 56.4% were males. A close contact with soil and water was identified in 30 patients (76.9%). Pneumonia was the main radiological feature (82.3%). Eleven patients were severe cases. Twenty-four (61.5%) patients died including 13 who died within 61 days after discharge. Of the deceased, 23 did not receive any antibiotics effective against B. pseudomallei. Effective drugs that were available did not include ceftazidime. Mean total illness-related costs was of US$65 (range $25-$5000). Almost two-thirds (61.5%) incurred debt and 28.2% sold land or other belongings to pay illness-related costs. CONCLUSIONS: The observed high fatality rate is likely explained by the lack or limited access to efficient antibiotics and under-recognition of the disease among clinicians, which led to inappropriate therapy.

RESUMO

The experience of childbirth has been technologized worldwide, leading to major social changes. In France, childbirth occurs almost exclusively in hospitals. Few studies have been published on the opinions of French women regarding obstetric technology and, in particular, caesarean section. In 2017-2018, we used a mixed methods approach to determine French women's preferences regarding the mode of delivery, and captured their experiences and satisfaction in relation to childbirth in two maternity settings. Of 284 pregnant women, 277 (97.5%) expressed a preference for vaginal birth, while seven (2.5%) women expressed a preference for caesarean section. Vaginal birth was also preferred among 26 women who underwent an in-depth interview. Vaginal birth was perceived as more natural, less risky and less painful, and to favour mother-child bonding. This vision was shared by caregivers. The women who expressed a preference for vaginal birth tended to remain sexually active late in their pregnancy, to find sexual intercourse pleasurable, and to believe that vaginal birth would not enlarge their vagina. A large majority (94.5%) of women who gave birth vaginally were satisfied with their childbirth experience, compared with 24.3% of those who underwent caesarean section. The caring attitude of the caregivers contributed to increasing this satisfaction. The notion of women's 'empowerment' emerged spontaneously in women's discourse in this research: women who gave birth vaginally felt satisfied and empowered. The vision shared by caregivers and women that vaginal birth is a natural process contributes to the stability of caesarean section rates in France.

RESUMO

Maternal group B Streptococcus (GBS) colonization is a major risk factor for neonatal GBS infection. However, data on GBS are scarce in low- and middle-income countries. Using sociodemographic data and vaginal swabs collected from an international cohort of mothers and newborns, this study aimed to estimate the prevalence of GBS colonization among pregnant women in Madagascar (n = 1,603) and Senegal (n = 616). The prevalence was 5.0% (95% CI, 3.9-6.1) and 16.1% (95% CI, 13.1-19.0) in Madagascar and Senegal, respectively. No factors among sociodemographic characteristics, living conditions, and obstetric history were found to be associated independently with GBS colonization in both countries. This community-based study provides one of the first estimates of maternal GBS colonization among pregnant women from Madagascar and Senegal.

RESUMO

Improving the quality of maternal and child healthcare (MCH) is a mandatory step on the path to reaching the Sustainable Development Goals and Universal Health Coverage. Quality improvement (QI) in MCH is a strong focus of the bilateral development cooperation provided by Germany to help strengthen the health systems of countries with high maternal and child mortality rates and/or with high unmet needs for family planning. In this article, we report on the findings of an analysis commissioned by a community of practice on MCH, of Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ). The objectives were to review the QI interventions implemented through programmes which have received technical assistance from GIZ on behalf of the German Federal Ministry for Economic Cooperation and Development in 14 Asian and African countries, to identify and describe the existing approaches and their results, and finally to draw lessons learnt from their implementation. Our analysis of the information contained in programme documents and reports identified five main methodologies used to improve the quality of care: capacity-building and supervision, governance and regulation, systemic QI at facility level, support to infrastructures, and community support. It is difficult to attribute the observed progresses in maternal and neonatal health to a particular agency, programme or intervention. We acknowledge that systemic implementation research embedded within the programmes would facilitate an understanding of the determinants of successful QI interventions, would better assess their effectiveness, and therefore better guide future bilateral aid programmatic decisions.
