Nasopharyngeal carriage of aerobic Gram-negative bacilli (GNB) may precede the development of invasive respiratory infections. We assessed the prevalence of nasopharyngeal carriage of aerobic GNB and their antimicrobial resistance patterns among healthy under-five children attending seven selected day-care centres in the Accra metropolis of the Greater Accra region of Ghana from September to December 2016. This cross-sectional study analysed a total of 410 frozen nasopharyngeal samples for GNB and antimicrobial drug resistance. The GNB prevalence was 13.9% (95% CI: 10.8–17.6%). The most common GNB were Escherichia coli (26.3%), Klebsiella pneumoniae (24.6%), and Enterobacter cloacae (17.5%). Resistance was most frequent for cefuroxime (73.7%), ampicillin (64.9%), and amoxicillin/clavulanic acid (59.6%). The organisms were least resistant to gentamicin (7.0%), amikacin (8.8%), and meropenem (8.8%). Multidrug resistance (MDR, being resistant to ≥3 classes of antibiotics) was observed in 66.7% (95% CI: 53.3–77.8%). Extended-spectrum beta-lactamase (ESBL)-producing bacteria constituted 17.5% (95% CI: 9.5–29.9%), AmpC-producing bacteria constituted 42.1% (95% CI: 29.8–55.5%), and carbapenemase-producing bacteria constituted 10.5% (95% CI: 4.7–21.8%) of isolates. The high levels of MDR are of great concern. These findings are useful in informing the choice of antibiotics in empiric treatment of GNB infections and call for improved infection control in day-care centres to prevent further transmission.

Antimicrobial resistant (AMR) bacteria in effluents from seafood processing facilities can contribute to the spread of AMR in the natural environment. In this study conducted in Tema, Ghana, a total of 38 effluent samples from two seafood processing facilities were collected during 2021 and 2022, as part of a pilot surveillance project to ascertain the bacterial load, bacterial species and their resistance to 15 antibiotics belonging to the WHO AWaRe group of antibiotics. The bacterial load in the effluent samples ranged from 13–1800 most probable number (MPN)/100 mL. We identified the following bacterial species: E. coli in 31 (82%) samples, K. pneumoniae in 15 (39%) samples, Proteus spp. in 6 (16%) samples, P. aeruginosa in 2 (5%) samples and A. baumannii in 2 (5%) samples. The highest levels of antibiotic resistance (100%) were recorded for ampicillin and cefuroxime among Enterobacteriaceae. The WHO priority pathogens—E. coli (resistant to cefotaxime, ceftazidime and carbapenem) and K.pneumoniae (resistant to ceftriaxone)—were found in 5 (13%) effluent samples. These findings highlight the need for enhanced surveillance to identify the source of AMR and multi-drug resistant bacteria and an adoption of best practices to eliminate these bacteria in the ecosystem of the seafood processing facilities.

Implementing and monitoring infection prevention and control (IPC) measures at immigration points of entry (PoEs) is key to preventing infections, reducing excessive use of antimicrobials, and tackling antimicrobial resistance (AMR). Sierra Leone has been implementing IPC measures at four PoEs (Queen Elizabeth II Quay port, Lungi International Airport, and the Jendema and Gbalamuya ground crossings) since the last Ebola outbreak in 2014–2015. We adapted the World Health Organization IPC Assessment Framework tool to assess these measures and identify any gaps in their components at each PoE through a cross-sectional study in May 2021. IPC measures were Inadequate (0–25%) at Queen Elizabeth II Quay port (21%; 11/53) and Jendema (25%; 13/53) and Basic (26–50%) at Lungi International Airport (40%; 21/53) and Gbalamuya (49%; 26/53). IPC components with the highest scores were: having a referral system (85%; 17/20), cleaning and sanitation (63%; 15/24), and having a screening station (59%; 19/32). The lowest scores (0% each) were reported for the availability of IPC guidelines and monitoring of IPC practices. This was the first study in Sierra Leone highlighting significant gaps in the implementation of IPC measures at PoEs. We call on the AMR multisectoral coordinating committee to enhance IPC measures at all PoEs.

ABSTRACT: Kenya's post-election violence in early 2008 created considerable problems for health services, and in particular, those providing HIV care. It was feared that the disruptions in services would lead to widespread treatment interruption. MSF had been working in the Kibera slum for 10 years and was providing antiretroviral therapy to 1800 patients when the violence broke out. MSF responded to the crisis in a number of ways and managed to keep HIV services going. Treatment interruption was less than expected, and MSF profited from a number of "lessons learned" that could be applied to similar contexts where a stable situation suddenly deteriorates.

BACKGROUND
In Burundi, the annual incidence of obstetric fistula is estimated to be 0.2-0.5% of all deliveries, with 1000-2000 new cases per year. Despite this relatively high incidence, national capacity for identifying and managing obstetric fistula is very limited. Thus, in July 2010, Medecins Sans Frontieres (MSF) set up a specialised Obstetric Fistula Centre in Gitega (Gitega Fistula Centre, GFC), the only permanent referral centre for obstetric fistula in Burundi. A comprehensive model of care is offered including psychosocial support, conservative and surgical management, post-operative care and follow-up. We describe this model of care, patient outcomes and the operational challenges.
METHODS
Descriptive study using routine programme data.
RESULTS
Between July 2010 and December 2011, 470 women with obstetric fistula presented for the first time at GFC, of whom 458 (98%) received treatment. Early urinary catheterization (conservative management) was successful in four out of 35 (11%) women. Of 454 (99%) women requiring surgical management, 394 (87%) were discharged with a closed fistula, of whom 301 (76%) were continent of urine and/or faeces, while 93 (24%) remained incontinent of urine and/or faeces. In 59 (13%) cases, the fistula was complex and could not be closed. Outcome status was unknown for one woman. Median duration of stay at GFC was 39 days (Interquartile range IQR, 31-51 days).
CONCLUSION
In a rural African setting, it is feasible to implement a comprehensive package of fistula care using a dedicated fistula facility, and satisfactory surgical repair outcomes can be achieved. Several operational challenges are discussed.

OBJECTIVES
In a rural district hospital in Burundi offering Emergency Obstetric care-(EmOC), we assessed the a) characteristics of women at risk of, or with an obstetric complication and their types b) the number and type of obstetric surgical procedures and anaesthesia performed c) human resource cadres who performed surgery and anaesthesia and d) hospital exit outcomes.
METHODS
A retrospective analysis of EmOC data (2011 and 2012).
RESULTS
A total of 6084 women were referred for EmOC of whom 2534(42%) underwent a major surgical procedure while 1345(22%) required a minor procedure (36% women did not require any surgical procedure). All cases with uterine rupture(73) and extra-uterine pregnancy(10) and the majority with pre-uterine rupture and foetal distress required major surgery. The two most prevalent conditions requiring a minor surgical procedure were abortions (61%) and normal delivery (34%).
A total of 2544 major procedures were performed on 2534 admitted individuals. Of these, 1650(65%) required spinal and 578(23%) required general anaesthesia; 2341(92%) procedures were performed by ‘general practitioners with surgical skills’ and in 2451(96%) cases, anaesthesia was provided by nurses. Of 2534 hospital admissions related to major procedures, 2467(97%) were discharged, 21(0.8%) were referred to tertiary care and 2(0.1%) died.
CONCLUSION
Overall, the obstetric surgical volume in rural Burundi is high with nearly six out of ten referrals requiring surgical intervention. Nonetheless, good quality care could be achieved by trained, non-specialist staff. The post-2015 development agenda needs to take this into consideration if it is to make progress towards reducing maternal mortality in Africa.

In an urban district hospital in Burkina Faso we investigated the relative proportions of HIV-1, HIV-2 and HIV-1/2 among those tested, the baseline sociodemographic and clinical characteristics, and the response to and outcome of antiretroviral therapy (ART). A total of 7368 individuals (male=32%; median age=34 years) were included in the analysis over a 6 year period (2002-2008). The proportions of HIV-1, HIV-2 and dual infection were 94%, 2.5% and 3.6%, respectively. HIV-1-infected individuals were younger, whereas HIV-2-infected individuals were more likely to be male, have higher CD4 counts and be asymptomatic on presentation. ART was started in 4255 adult patients who were followed up for a total of 8679 person-years, during which time 469 deaths occurred. Mortality differences by serotype were not statistically significant, but were generally worse for HIV-2 and HIV-1/2 after controlling for age, CD4 count and WHO stage. Among severely immune-deficient patients, mortality was higher for HIV-2 than HIV-1. CD4 count recovery was poorest for HIV-2. HIV-2 and dually infected patients appeared to do less well on ART than HIV-1 patients. Reasons may include differences in age at baseline, lower intrinsic immune recovery in HIV-2, use of ineffective ART regimens (inappropriate prescribing) by clinicians, and poor drug adherence.

Setting: In 1995, a rapid response project for humanitarian and medical emergencies, including outbreak responses, named ‘Pool d’Urgence Congo’ (PUC), was implemented in the Democratic Republic of Congo by Médecins Sans Frontières.
Objective: To assess the outcomes of cholera and measles outbreak alerts that were received in the PUC surveillance system between 2016 and 2018.
Design: This was a retrospective cross-sectional study.
Results: Overall, 459 outbreak alerts were detected, respectively 69% and 31% for cholera and measles. Of these, 32% were actively detected and 68% passively detected. Most alerts (90%) required no intervention and 10% of alerts had an intervention. There were 25% investigations that were not carried out despite thresholds being met; 17% interventions were not performed, the main reported reason being PUC operational capacity was exceeded. Confirmed cholera and measles outbreaks that met an investigation threshold comprised respectively 90% and 76% of alerts; 59% of measles investigations were followed by a delayed outbreak response of 14 days (n = 10 outbreaks).
Conclusion: Some alerts for cholera and measles outbreaks that were detected in the PUC system did not lead to a response even when required; the main reported reason was limited operational capacity to respond to all of them.
