INTRODUCTION
Conflicts frequently occur in countries with high maternal and neonatal mortality and can aggravate difficulties accessing emergency care. No literature is available on whether the presence of conflict influences the outcomes of mothers and neonates during Caesarean sections (C-sections) in high-mortality settings.
OBJECTIVE
To determine whether the presence of conflict was associated with changes in maternal and neonatal mortality during C-sections.
METHODS
We analysed routinely collected data on C-sections from 17 Médecins Sans Frontières (MSF) health facilities in 12 countries. Exposure variables included presence and intensity of conflict, type of health facility and other types of access to emergency care.
RESULTS
During 2008–2015, 30,921 C-sections were performed in MSF facilities; of which 55.4% were in areas of conflict. No differences were observed in maternal mortality in conflict settings (0.1%) vs. non-conflict settings (0.1%) (P = 0.08), nor in neonatal mortality between conflict (12.2%) and non-conflict settings (11.5%) (P = 0.1). Among the C-sections carried out in conflict settings, neonatal mortality was slightly higher in war zones compared to areas of minor conflict (P = 0.02); there was no difference in maternal mortality (P = 0.38).
CONCLUSIONS
Maternal and neonatal mortality did not appear to be affected by the presence of conflict in a large number of MSF facilities. This finding should encourage humanitarian organisations to support C-sections in conflict settings to ensure access to quality maternity care.

BACKGROUND
In developing countries such as Pakistan, poor training of mid-level cadres of health providers, combined with unregulated availability of labour-inducing medication can carry considerable risk for mother and child during labour. Here, we describe the exposure to labour-inducing medication and its possible risks in a vulnerable population in a conflict-affected region of Pakistan.
METHODS
A retrospective cohort study using programme data, compared the outcomes of obstetric risk groups of women treated with unregulated oxytocin, with those of women with regulated treatment.
RESULTS
Of the 6379 women included in the study, 607 (9.5%) received labour-inducing medication prior to reaching the hospital; of these, 528 (87.0%) received unregulated medication. Out of 528 labour-inducing medication administrators, 197 (37.3%) traditional birth attendants (also known as dai) and 157 (29.7%) lady health workers provided unregulated treatment most frequently. Women given unregulated medication who were diagnosed with obstructed/prolonged labour were at risk for uterine rupture (RR 4.1, 95% CI 1.7–9.9) and severe birth asphyxia (RR 3.9, 95% CI 2.5–6.1), and those with antepartum haemorrhage were at risk for stillbirth (RR 1.8, 95% CI 1.0–3.1).
CONCLUSIONS
In a conflict-affected region of Pakistan, exposure to unregulated treatment with labour-inducing medication is common, and carries great risk for mother and child. Tighter regulatory control of labour-inducing drugs is needed, and enhanced training of the mid-level cadres of healthcare workers is required

Provision of Emergency Obstetric and Neonatal Care (EmONC) reduces maternal mortality and should include three components: Basic Emergency Obstetric and Neonatal Care (BEmONC) offered at primary care level, Comprehensive EmONC (CEmONC) at secondary level and a good referral system in-between. In a conflict-affected province of Afghanistan (Khost), we assessed the performance of an Médecins Sans Frontières (MSF) run CEmONC hospital without a primary care and referral system. Performance was assessed in terms of hospital utilisation for obstetric emergencies and quality of obstetric care.

INTRODUCTION
Inappropriate use of antibiotics is widespread, and one of the main drivers for antimicrobial resistance (AMR). In pregnant women with suspected urinary tract infection (UTI), studies have suggested antibiotic over-use in up to 96%; use may be particularly high in settings with limited diagnostic resources and where reliant on symptomatic approaches. In south Beirut, specifically within camps where refugees settle and living conditions are poor, MSF has been operational since 2014 as the main provider of free primary healthcare services as well as sexual and reproductive health (SRH) care. Current MSF protocols operational in this setting recommend the use of urine dipsticks for UTI screening in pregnant women, followed by empirical antibiotic treatment for those with a positive result (positive for nitrites and/or leucocytes).
METHODS
In 2021, around 6,300 (24%) of the total 26,300 antenatal care (ANC) consultations conducted had a suspected UTI, based on urine dipstick results, and all those suspected with UTI were prescribed antibiotics. A prospective study was conducted between April and July 2022, to determine if adding urine
culture, following positive urine dipstick, to the protocol would reduce the use of unnecessary antibiotics. We used descriptive statistics to describe the population and compare positive and negative urine cultures. We calculated the proportion of patients receiving appropriate or inappropriate antibiotics.
ETHICS
This study was approved by the MSF Ethics Review Board, and by the ethics committee of the Lebanese American University.
RESULTS
A total of 449 pregnant women with suspected UTI were included in this study; all received urine culture. 81 (18%) were culture-positive. Under usual practice, 368 women (82%) would have been overprescribed antibiotics, based solely on urine dipstick results. 197 (44%) of the cohort were symptomatic, and were given empirical antibiotic treatment, with cefixime administered to 42 (21%) women and fosfomycin to 155 (79%). Escherichia coli (79%) was the most common bacterial species isolated, followed by Proteus (11%). In addition, among the 81 positive cultures, 4 (5%) were found resistant to fosfomycin and 39 (48%) to cefixim
CONCLUSION
These study findings reinforce concern around potential over prescription of unnecessary antibiotics in such populations, which could contribute to a potential rise in AMR. In addition, resistance to cefixime, one of the recommended antibiotics to treat UTI’s, is relatively high in this community. In contexts where urine culture is feasible, not costly, accessible, and results rapidly available, particularly with large cohorts of patients, urine culture should be the main method used to diagnose UTI; treatment should be based on microbiology/antibiotic sensitivity results.

INTRODUCTION
Cervical cancer is now largely a preventable disease; however, implementation of highly sensitive molecular screening technologies in low-resource settings is partly hindered by the need for intensive investment in equipment and highly trained, skilled laboratory personnel. Resource limitations often preclude the possibility of same-day screening and treatment, as recommend by WHO. We sought to assess the diagnostic accuracy of self-collected versus nurse-collected high vaginal samples (HVS) for human papillomavirus (HPV) screening using GeneXpert, for within-country validation and to further inform its scale-up within routine point-of-care testing in primary healthcare systems.
METHODS
Consenting women presenting for routine cervical screening in selected health facilities in Gutu District, Zimbabwe, were asked to provide three HVS obtained at the same time on a single visit; the first, self-collected, and the following two, nurse-collected. Nurse-collected HVS were tested with GeneXpert (Cepheid, Sunnyvale, USA) and Cobas HPV (Roche, Pleasanton, USA; used as the reference test), whilst self-collected HVS were tested only using GeneXpert. Those testing positive on the reference test were offered visual inspection with acetic acid and cervicography (VIAC). Women with a positive VIAC examination were offered cryotherapy or loop electrosurgical excision procedure.
ETHICS
This study was approved by the MSF Ethics Review Board.
RESULTS
279 participants consented to provide HVS; none reported discomfort or side effects during or after swabbing. Among nurse-collected HVS, 11/279 participants were found positive on genotyping for HPV-16 using Cobas HPV, and nine of 279 were positive using GeneXpert. Eight out of 279 were identified on genotyping for HPV-18/45 using both platforms. The sensitivities of testing for HPV-16 and 18/45 using GeneXpert as compared to the reference test, Cobas, were 89% (95%CI 53-100) and 63% (95%CI 25-92) respectively. The sensitivity of self- and nurse-collected HVS for HPV-16 tested using GeneXpert, as compared to the reference test, was 89% (eight of nine; 95%CI 52-100). Specificity was 100% (95%CI 97-100), with a positive predictive value of 89% (95%CI 52-100), and negative predictive value of 100% (95%CI 97-100). However, sensitivity for detection of HPV-18/45 was 68.3% (95%CI 34-100).
CONCLUSION
Performance of cervical cancer screening using self-collected HVS tested with GeneXpert is comparable to that with nurse-collected HVS. Integrated GeneXpert platforms are already in wide use, enabling rapid diagnosis of tuberculosis, detection of HIV viral load, and early infant diagnosis of HIV, using a single piece of equipment. Deploying GeneXpert for HPV screening using self-collected HVS could help to provide timely results, especially in settings where VIAC is unavailable.

BACKGROUND:
In high syphilis prevalence settings, the syphilis testing and treatment strategy for mothers and newborns must be tailored to balance the risk of over treatment against the risk of missing infants at high-risk for congenital syphilis. Adding a non-treponemal test (Rapid Plasma Reagin - RPR) to a routine rapid treponemal test (SD Bioline Syphilis 3.0) for women giving birth can help distinguish between neonates at high and low-risk for congenital syphilis to tailor their treatment. Treatment for neonates born to RPR-reactive mothers (high-risk) is 10 days of intravenous penicillin, while one dose of intramuscular penicillin is sufficient for those born to RPR non-reactive mothers (low-risk). This strategy was adopted in March 2017 in a Médecins Sans Frontières supported hospital in Bangui, Central African Republic. This study examined the operational consequences of this algorithm on the treatment of newborns.
METHODS:
The study was a retrospective cohort study. Routine programmatic data were analysed. Descriptive statistical analysis was done. Total antibiotic days, hospitalization days and estimated costs were compared to scenarios without RPR testing and another where syphilis treatment was the sole reason for hospitalization.
RESULTS:
Of 202 babies born to SD Bioline positive mothers 89 (44%) and 111(55%) were RPR-reactive and non-reactive respectively (2 were unrecorded) of whom 80% and 88% of the neonates received appropriate antibiotic treatment respectively. Neonates born to RPR non-reactive mothers were 80% less likely to have sepsis [Relative risk (RR) = 0.20; 95% Confidence interval (CI) = 0.04-0.92] and 9% more likely to be discharged [RR = 1.09; 95% CI = 1.00-1.18] compared to those of RPR-reactive mothers. There was a 52%, and 49% reduction in antibiotic and hospitalization days respectively compared to a scenario with SD-Bioline testing only. Total hospitalization costs were also 52% lower compared to a scenario without RPR testing.
CONCLUSIONS:
This testing strategy can help identify infants at high and low risk for congenital syphilis and treat them accordingly at substantial cost savings. It is especially appropriate for settings with high syphilis endemicity, limited resources and overcrowded maternities. The babies additionally benefit from lower risks of exposure to unnecessary antibiotics and nosocomial infections.
