Fungal biomarkers in HIV-associated disseminated histoplasmosis: a multicenter diagnostic accuracy study on the Guiana shield.

Background: Diagnosis of HIV-associated histoplasmosis remains challenging. Our objective was to compare the performances of (1→3)-β-D-Glucan (BDG) and Aspergillus galactomannan (GM) antigen for the diagnosis of HIV-associated histoplasmosis.

Methods: We performed a diagnostic accuracy study using frozen primary serum specimens issued from consecutive hospitalized people living with HIV (PLWH) and blindly tested for BDG and GM using Fungitell® and PlateliaTM Aspergillus, respectively.

Which diagnostic test to use for Testing and Treatment strategies in low-transmission settings: a secondary analysis of a longitudinal interventional study.

Background: The lack of sensitive field tests to diagnose blood stages and hypnozoite carriers prevents Testing and Treatment (TAT) strategies to achieve elimination in low-transmission settings, but recent advances in Polymerase Chain Reaction (PCR) and serology position them as promising tools. This study describes a PCR-based TAT strategy (PCRTAT) implemented in Saint Georges (SGO), French Guiana, and explores alternative strategies (seroTAT and seroPCRTAT) to diagnose and treat carriers.

Methods: The PALUSTOP cohort study implemented in SGO (September 2017 to December 2018) screened participants for using PCR tests and treated positive cases.

Tackling a worrisome rate of lost to follow-up among migrants with hepatitis B in French Guiana.

Objectives: Management of Hepatitis B virus (HBV)-infected patients, whether they are receiving treatment or not, necessitates long-term follow-up. This study evaluated the rate of lost to follow-up (LTFU) among HBV-infected patients and the feasibility of a callback strategy to re-engage these patients in HBV care.

Patients And Methods: We conducted a retrospective study involving HBV-infected patients attending the outpatient clinic at Cayenne Hospital, French Guiana.

Overweight and Obesity in People Living With Type 1 Diabetes: A Cross-Sectional Analysis of the BETTER Registry.

Aims: The prevalence and associations of overweight and obesity in Canadian adult people living with type 1 diabetes (PWT1D) are poorly documented. In a cohort of PWT1D patients, this study assesses (i) overweight and obesity frequencies and associated PWT1D clinicodemographic characteristics, (ii) diabetes characteristics, and (iii) the use of noninsulin adjunctive agents.

Materials And Methods: Cross-sectional analysis of self-reported data from the BETTER registry: 1091 adult PWT1D (aged 44.

Organ Involvement Related to Death in Critically Ill Patients With Leptospirosis: Unsupervised Analysis in a French West Indies ICU.

Objectives: To identify distinct phenotypes of critically ill leptospirosis patients upon ICU admission and their potential associations with outcome.

Design: Retrospective observational study including all patients with biologically confirmed leptospirosis admitted to the ICU between January 2014 and December 2022. Subgroups of patients with similar clinical profiles were identified by unsupervised clustering (factor analysis for mixed data and hierarchical clustering on principal components).

Clinical and parasitological features of Leishmania infection among gold miners in the Oiapoque basin, an international Brazil-French Guiana border.

Gold miners working illegally in mines live in poor health conditions related to their strenuous work and precarious housing. Therefore, they are at higher risk for infectious diseases. American tegumentary leishmaniasis (ATL) appears to be of great concern to the population living in the Guiana Shield region.

Core principles of Malakit intervention for transferability in other contexts.

To eliminate malaria, all populations must be included. For those who are not reached by the health care system, specific interventions must be tailor-made. An innovative Malakit strategy, based on the distribution of self-diagnosis and self-treatment kits, has been evaluated in the Suriname-French Guiana- Amapá (Brazil) region.

Kinetics of glucose-6-phosphate dehydrogenase (G6PD) activity during Plasmodium vivax infection: implications for early radical malaria treatment.

Background: Plasmodium vivax relapses due to dormant liver hypnozoites can be prevented with primaquine. However, the dose must be adjusted in individuals with glucose-6-phosphate-dehydrogenase (G6PD) deficiency. In French Guiana, assessment of G6PD activity is typically delayed until day (D)14 to avoid the risk if misclassification.

Small for Gestational Age Newborns in French Guiana: The Importance of Health Insurance for Prevention.

Small for gestational age (SGA) newborns have a higher risk of poor outcomes. French Guiana (FG) is a territory in South America with poor living conditions. The objectives of this study were to describe risk factors associated with SGA newborns in FG.

Tuberculosis in prison: What about after release? The example of French Guiana.

Introduction: Tuberculosis is a major cause of mortality worldwide. Prisoners in Guiana have multiple risk factors. The primary objective of this study was to describe tuberculosis occurring in prison and after release in French Guiana between 2008 and 2020.

Prenatal and Postnatal Ocular Abnormalities Following Congenital Zika Virus Infections: A Systematic Review.

Objective: To assess fetal and neonatal eyes abnormalities and their progression during the last ZIKV outbreak and summarize learned lessons.

Methods: A systematic review and meta-analysis was conducted by a team of obstetricians and ophthalmologists.

Results: Studies reporting ocular abnormalities during the prenatal ( = 5) and postnatal ( = 24) periods were included in the analysis.

Understanding the impact of mobility on Plasmodium spp. carriage in an Amazon cross-border area with low transmission rate.

Despite the large reduction in malaria incidence in the last decade, the last kilometre to elimination is often the hardest, especially in international border areas. This study investigated the impact of mobility on Plasmodium spp. carriage in people living in a cross-border area in Amazonia with a low malaria transmission rate.

Training-of-trainers program for community health workers involved in an innovative and community-based intervention against malaria among goldminers in the Guiana shield: a quality and effectiveness evaluation.

Introduction: An innovative and community-based intervention is implemented in the Guiana Shield to eliminate malaria among people involved in artisanal and small-scale gold mining. The intervention consists of the distribution of malaria self-management kits to goldminers and the presumptive treatment for individuals at risk of carrying hypnozoites. The intervention is possible owing to community health workers (CHWs) who are previously trained to master all intervention procedures, including health education activities and goldmining training.

Social determinants of health among people working on informal gold mines in French Guiana: a multicentre cross-sectional survey.

Introduction: Social determinants of health, such as living and working conditions, economical and environmental context and access to care, combine to impact the health of individuals and communities. In French Guiana (FG), the persons working in informal artisanal and small-scale gold mining in the rainforest are a particularly vulnerable population which lives in precarious conditions and far from the health system. Previous studies have demonstrated their high morbidity due to infectious diseases.

Respective roles of social deprivation, health literacy, and clinical factors for COVID-19: a case-control study in hospitalized patients.

Introduction: To investigate the association between social deprivation and COVID-19 among hospitalized patients in an underprivileged department of the greater Paris area.

Methods: Individuals hospitalized for COVID-19 between March 1st and October 31, 2020, were included, matched on age and sex, and compared with patients hospitalized for any other reason with negative RT-PCR for SARS-CoV-2, through a case-control study. Clinical, socio-demographic characteristics, health literacy, and social deprivation, assessed by the EPICES score, were collected.

Mitoxantrone in NMO Spectrum Disorder in a Large Multicenter Cohort in French Caribbean.

Background And Objectives: Preventing relapses in neuromyelitis Optica spectrum disorder (NMOSD) is a primary goal. New effective molecules are often expensive and not readily available in regions with fragile health systems. Assessing the efficacy and safety of less costly therapeutic alternatives is necessary.
