The HPV-Automated Visual Evaluation (PAVE) Consortium is validating a cervical screening strategy enabling accurate cervical screening in resource-limited settings. A rapid, low-cost HPV assay permits sensitive HPV testing of self-collected vaginal specimens; HPV-negative women are reassured. Triage of positives combines HPV genotyping (four groups in order of cancer risk) and visual inspection assisted by automated cervical visual evaluation (AVE) that classifies cervical appearance as severe, indeterminate, or normal. Together, the combination predicts which women have precancer, permitting targeted management to those most needing treatment.


We analyzed CIN3+ yield for each PAVE risk level (HPV genotype crossed by AVE classification) from nine clinical sites (Brazil, Cambodia, Dominican Republic, El Salvador, Eswatini, Honduras, Malawi, Nigeria, and Tanzania). Data from 1832 HPV-positive participants confirmed that HPV genotype and AVE classification each strongly and independently predict risk of histologic CIN3+. The combination of these low-cost tests provided excellent risk stratification, warranting pre-implementation demonstration projects.

BACKGROUND

Conflict-related sexual violence (CRSV) is a significant health and human rights issue in humanitarian contexts, but there is a need of further research on differences between sexes in terms of severity of symptoms and improvement. Consequently, we explored the differences in severity and outcomes among male and female survivors of CRSV who received mental health and psychosocial support (MHPSS) in an armed conflict setting.


METHODS

We retrospectively analysed medical records from 3442 CRSV survivors in a MHPSS programme in Borno State, Nigeria, between 2018 and 2019. Patient characteristics, severity (measured with Clinical Global Impression of Severity Scale [CGI-S scale]), and improvement (measured with Clinical Global Impression of improvement [CGI-I] scale) were assessed by an attending counsellor. We assessed predictors for severity and improvement using a multivariable logistic regression analysis and time to improvement by sex using Kaplan Meier (K-M) curves and Cox regression.


RESULTS

We included 3442 patients who had at least one CRSV event in this study (2955 [85.9%] female, 486 [14.1%] male, one unknown). The most prevalent categories of symptoms were depression (49.9%; n = 1716), post-traumatic (25.6%; n = 879), and anxiety (20.3%; n = 697) symptoms. Most patients had mild (59.0%; n = 1869/3170) or moderate (36.4%; n = 1153/3170) symptoms at baseline, with 4.7% having severe symptoms (n = 148/3170). The logistic regression analysis (n = 1106), showed male patients had a 59% higher odds of severe symptoms at baseline than female patients (aOR 1.59; 95% CI 1.04-2.45). Among males, those older than 55 years had three times higher odds of presenting severe symptoms than younger patients (aOR 3.65; 95% CI 1.43-9.34). Women aged 36-55 years were more likely to present improvement than younger female patients (aOR 1.32; 95% CI 1.11-1.58). For both sexes, prompt attention after a CRSV event (≤ 3 days) positively predicted improvement (aOR 13.9; 95% CI 1.48-130 males, aOR 2.11; 95% CI 1.22-3.64 females) compared to late attention. Time to improvement did not differ between sexes, with an average of at least three consultations needed to achieve improvement.


CONCLUSIONS

Our study suggests that psychological attention of survivors within the first 72 h should be a priority. MHPSS programmes addressing CRSV should be inclusive to all patients, and gender-neutral approaches to ensure access, safety, confidentiality, and non-discrimination for all survivors should be developed.

Field evaluation of validity and feasibility of Pan-Lassa rapid diagnostic test for Lassa fever in Abakaliki, Nigeria: a prospective diagnostic accuracy study

Lancet Infect Dis. 1 September 2024; Volume 24 (Issue 9); 1037-1044.; DOI:10.1016/S1473-3099(24)00184-1

BACKGROUND
Lassa fever is a viral haemorrhagic fever with few options for diagnosis and treatment; it is also under-researched with knowledge gaps on its epidemiology. A point-of-care bedside test diagnosing Lassa fever, adhering to REASSURED criteria, is not currently available but is urgently needed in west African regions with high Lassa fever burden. We aimed to assess the validity and feasibility of a rapid diagnostic test (RDT) to confirm Lassa fever in people in Nigeria.

METHODS
We estimated the diagnostic performance of the ReLASV Pan-Lassa RDT (Zalgen Labs, Frederick, MD, USA) as a research-use-only test, compared to RT-PCR as a reference standard, in 217 participants at a federal tertiary hospital in Abakaliki, Nigeria. We recruited participants between Feb 17, 2022, and April 17, 2023. The RDT was performed using capillary blood at the patient bedside and using plasma at the laboratory. The performance of the test, based on REASSURED criteria, was assessed for user friendliness, rapidity and robustness, sensitivity, and specificity.

FINDINGS
Participants were aged between 0 and 85 years, with a median age of 33·0 years (IQR 22·0-44·3), and 24 participants were younger than 18 years. 107 (50%) participants were women and 109 (50%) were men; one participant had missing sex data. Although the specificity of the Pan-Lassa RDT was high (>90%), sensitivity at bedside using capillary blood was estimated as 4% (95% CI 1-14) at 15 min and 10% (3-22) at 25 min, far below the target of 90%. The laboratory-based RDT using plasma showed better sensitivity (46% [32-61] at 15 min and 50% [36-64] at 25 min) but did not reach the target sensitivity. Among the 52 PCR-positive participants with Lassa fever, positive RDT results were associated with lower cycle threshold values (glycoprotein precursor [GPC] gene mean 30·3 [SD 4·3], Large [L] gene mean 32·3 [3·7] vs GPC gene mean 24·5 [3·9], L gene mean 28·0 [3·6]). Personnel conducting the bedside test procedure reported being hindered by the inconvenient use of full personal protective equipment and long waiting procedures before a result could be read.

INTERPRETATION
The Pan-Lassa RDT is not currently recommended as a diagnostic or screening tool for suspected Lassa fever cases. Marked improvement in sensitivity and user friendliness is needed for the RDT to be adopted clinically. There remains an urgent need for better Lassa fever diagnostics to promote safety of in-hospital care and better disease outcomes in low-resource settings.

BACKGROUND

Abortion-related complications remain a main cause of maternal mortality. There is little evidence on the availability and quality of post-abortion care (PAC) in humanitarian settings. We assessed the quality of PAC in two hospitals supported by an international organization in Jigawa State (Nigeria) and Bangui (Central African Republic, CAR).


METHODS

We mapped indicators corresponding to the eleven domains of the WHO Maternal and Newborn Health quality-of-care framework to assess inputs, processes (provision and experience of care), and outcomes of PAC. We measured these indicators in four components of a cross-sectional multi-methods study: 1) an assessment of the hospitals’ PAC signal functions, 2) a survey of the knowledge, attitudes, practices, and behavior of 140 Nigerian and 84 CAR clinicians providing PAC, 3) a prospective review of the medical records of 520 and 548 women presenting for abortion complications and, 4) a survey of 360 and 362 of these women who were hospitalized in the Nigerian and CAR hospitals, respectively.


RESULTS

Among the total 27 PAC signal functions assessed, 25 were available in the Nigerian hospital and 26 in the CAR hospital. In both hospitals, less than 2.5% were treated with dilatation and sharp curettage. Over 80% of women received blood transfusion or curative antibiotics when indicated. However, antibiotics were given to about 30% of patients with no documented indication. Among discharged women in CAR, 99% received contraceptive counseling but only 39% did in Nigeria. Over 80% of women in Nigeria reported positive experiences of respect and preservation of dignity. Conversely, in CAR, 37% reported that their privacy was always respected during examination and 62% reported short or very short waiting time before seeing a health provider. In terms of communication, only 15% felt able to ask questions during treatment in both hospitals. The risk of abortion-near-miss happening ≥ 24h after presentation was 0.2% in Nigeria and 1.1% in CAR. Only 65% of women in the Nigerian hospital and 34% in the CAR hospital reported that the staff provided them best care all the time.


CONCLUSIONS

Our comprehensive assessment identified that these two hospitals in humanitarian settings provided lifesaving PAC. However, hospitals need to strengthen the patient-centered approach engaging patients in their own care and ensuring privacy, short waiting times and quality provider-patient communication. Health professionals would benefit from instituting antibiotic stewardships to prevent antibiotic-resistance.

BACKGROUND

Noma is a gangrenous infection of the face that results in severe facial deformity, occurring primarily in malnourished and impoverished populations.


OBJECTIVE

To assess clinician- and patient-reported outcomes (PROs) before and after reconstructive surgery for patients with noma in northwest Nigeria.


METHODS

Objective outcomes were recorded using the noma-specific NOITULP (nose, outer cheek, inner cheek, trismus, upper/lower lip, particularities) classification system. PROs were recorded using a locally developed tool. Postsurgical changes were assessed by Wilcoxon signed-rank testing. Linear regression was used to look for associated risk factors. The inter-rater reliability (IRR) of the NOITULP score was assessed using the weighted kappa statistic.


RESULTS

Forty-nine patients (median age 25 years, 71% male) underwent local/regional flap reconstruction and/or trismus release. Twelve complications were reported. Univariate analysis showed a 3.20 change in PRO score (95% confidence interval 0.59 to 5.81, p = 0.018) per kilogram the patient underwent at time of surgery. The NOITULP score improved from a presurgery median of 3.5 to 2.3 (p < 0.0001), however, the IRR was poor (kappa = 0.0894, p < 0.0001). The PRO score also improved from a median of 7.0 to 12.0 (p < 0.0001).


CONCLUSIONS

Facial reconstructive surgery improves the NOITULP score and PROs in patients with noma in northwest Nigeria.

Recommendations for the management of malnutrition among infants aged less than 6 months (<6 m) are based on limited evidence. This study aimed to describe the characteristics, treatment outcomes and outcome‐associated factors among malnourished infants <6 m admitted at Médecins Sans Frontières (MSF) inpatient and ambulatory therapeutic feeding centres (ITFC and ATFC) in North–East Nigeria, 2019–2022. We conducted a descriptive analysis of the cohorts and logistic regression to measure the association between two selected outcomes—inpatient mortality and defaulting from the ambulatory programme—and possible factors associated. In total, 940 infants <6 m were admitted at ITFC. Most of them presented severe acute malnutrition and comorbidities, with diarrhoea being the most frequent. On discharge, 13.3% (n = 125) of infants were cured, 72.9% (n = 684) stabilized (referred to ATFC), 6.5% (n = 61) left against medical advice and 4.2% (n = 39) died. The median length of hospital stay was 10 days [IQR 7–14]. A hospital stay shorter than 10 days was significantly associated with inpatient mortality (aOR = 12.51, 95% confidence interval [CI] = 3.72–42.11, p ≤ 0.01). Among 561 infants followed up at the ATFC, only 2.8% reported comorbidities. On discharge, 80.9% (n = 429) were cured, 16.2% (n = 86) defaulted and 1.1% (n = 6) died. Male sex (aOR = 1.94, 95% CI = 1.15–3.27, p = 0.01), internally displaced status (aOR = 1.70, 95% CI = 1.05–2.79, p = 0.03) and <−3 WLZ (aOR = 1.95, 95% CI = 1.05–3.63, p = 0.03) were significantly associated with programme defaulting. Stabilization and recovery rates among malnourished infants <6 m in the studied project align with acceptable standards in this humanitarian setting. Notable defaulting rates from outpatient care should be further explored.More

The surge of diphtheria in 2023: Global overview, MSF responses & challenges

Amevoin Y, Ale F
Epicentre Scientific Day 2024. 23 May 2024
BACKGROUND
Diphtheria is an infection of the upper respiratory tract characterized by the production of an extracellular toxin. Individuals with incomplete immunization or low levels of antitoxin antibodies are particularly susceptible to infection. Specific treatment relies on Diphtheria Anti-Toxin (DAT) and the disease is preventable by active immunization. Since 2019, large outbreaks have been reported in WHO African Region, but 2023 has seen an unprecedented surge in diphtheria cases in West Africa, mainly Kano State, Nigeria.

METHODS
Médecins Sans Frontières (MSF) and Epicentre have been involved in response efforts but have faced several challenges due to limited hospital capacity and a global shortage of DAT. This led to the implementation of new solutions such as home-based care, adaptation of DAT dosage and strategic allocation of DAT stocks. Preliminary descriptive analysis shows the key figures from the 2023 diphtheria outbreak and summarizes critical insights from one year of MSF intervention in Kano.

RESULTS
MSF treated around 23 thousand individuals across 14 sites in five countries. Nearly half of these patients required hospitalization, with an overall case fatality rate (CFR) of 6%. The majority of patients were under 15 years of age, and most were female.
In Kano State, Nigeria, specifically, three main centres were established at the peak of the outbreak. MSF used adaptive strategies to deal with the constraints of the response, which were phased according to the number of cases and the availability of drugs. Centralised case management was used for severe cases, while a decentralised care model, including home-based care, was used for mild and close contacts. The primary centre, which remains operational, has received approximately 9 thousand patients.
Data indicate that the prompt administration of diphtheria antitoxin (DAT) may influence patient outcomes. Furthermore, an early immunization campaign could have potentially reduced the overall mortality rate associated with the epidemic.

CONCLUSION
The surge of diphtheria in West Africa highlighted numerous challenges in combating the disease in low-resource settings, particularly concerning the availability of diphtheria antitoxin (DAT). Further analyses are required to accurately assess the impact of home-based care and DAT dosage strategies. Scaling up global DAT production and enhancing routine vaccination programs could be crucial in preventing future outbreaks.
