Six-monthly appointment spacing for clinical visits as a model for retention in HIV Care in Conakry-Guinea: a cohort study

BMC Infectious Diseases, 2017
Background The outbreak of the Ebola virus disease (EVD) in 2014 led to massive dropouts in HIV care in Guinea. Meanwhile, Médecins Sans Frontières (MSF) was implementing a six-monthly appointment spacing approach adapted locally as Rendez-vous de Six ...

Velocity gradient dependent structures of 12–2–12 wormlike micelles: insights from small‐angle neutron scattering in the 1–2 shear plane

Journal of Applied Crystallography, Volume 58, Issue 4, Page 1407-1416, August 2025.
A new 1–2 plane shear cell has been developed to observe structural changes and concentration fluctuations under flow fields depending on the velocity gradient, which cannot be measured by the Rheo‐SANS small‐angle neutron scattering technique.The velocity gradient dependent shear‐induced structural evolution of wormlike micelles (WLMs) formed by a ...

Incidence and characteristics of candidemia in hospitalised patients with advanced HIV in the Médecins Sans Frontières (MSF) hospital in Kinshasa, Democratic Republic of Congo (DRC)

AIDS Research and Therapy
Candidemia is an underrecognised complication among patients with advanced HIV disease (AHD), particularly in low‑resource settings. We conducted a retrospective study at an MSF-supported hospital in Kinshasa (2022–2025) to describe the incidence ...

Optimal weights and priors in simultaneous fitting of multiple small‐angle scattering datasets

Journal of Applied Crystallography, Volume 58, Issue 3, Page 934-947, June 2025.
Here, we determine the optimal weights and priors to use when simultaneously fitting small‐angle X‐ray and neutron scattering data.Small‐angle X‐ray and neutron scattering (SAXS and SANS) are powerful techniques in materials science and soft matter. This study addressed how multiple SAXS or SANS datasets are best weighted when performing simultaneous ...

Antimicrobial stewardship in primary health care programs in humanitarian settings: the time to act is now

Antimicrobial Resistance and Infection Control, 2023
Fragile and conflict-affected settings bear a disproportionate burden of antimicrobial resistance, due to the compounding effects of weak health policies, disrupted medical supply chains, and lack of knowledge and awareness about antibiotic stewardship ...

Shielded magnetic small‐angle neutron scattering for characterization of radioactive samples

Journal of Applied Crystallography, Volume 58, Issue 3, Page 1000-1014, June 2025.
The study presents a novel shielded magnetic small‐angle neutron scattering (SM‐SANS) technique using lead shielding to facilitate the nanoscale characterization of clustering and precipitation in highly radioactive nuclear materials. By comparing the results with atom probe tomography, the research demonstrates that SM‐SANS effectively quantifies ...

Post-traumatic osteomyelitis in Middle East war-wounded civilians: resistance to first-line antibiotics in selected bacteria over the decade 2006–2016

BMC Infectious Diseases, 2019
Background War-wounded civilians in Middle East countries are at risk of post-traumatic osteomyelitis (PTO). We aimed to describe and compare the bacterial etiology and proportion of first-line antibiotics resistant bacteria (FLAR) among PTO cases in ...
