RESUMO
BACKGROUND: Infant mortality in French Guiana, a French overseas territory, is 2.7 times greater than in mainland France. Given the importance of better understanding infant mortality we aimed to describe the early & late neonatal, and postneonatal mortality in French Guiana between 2007 and 2022. METHODS: We used data from the Institut National de la Statistique et des Etudes Economiques to describe trends and performed survival analysis. RESULTS: Overall, there were 1 073 deaths before one year of age, of which 297 (27.7 %) occurred on the first day of life. The overall proportion of early neonatal deaths was 47.1 %, late neonatal deaths was 17.3 %, and post-neonatal deaths was 35.6 %. The overall incidences were 4.6 per 1,000 for early neonatal mortality, 1.4 per 1,000 for late neonatal mortality, and 3.1 per 1,000 for post neonatal mortality. The incidence for infant mortality for French Guiana residents was thus 9.1 per 1,000. CONCLUSIONS: We show that post neonatal deaths in French Guiana are proportionally greater than in mainland France and they do not seem to decline, as they did in France. The relative proportions of post-neonatal mortality can thus help to identify important areas for action to correct excess infant mortality. Although poor pregnancy follow-up remains a problem we show that follow-up of infants is also a pressing problem that warrants increased efforts.
RESUMO
Preterm deliveries are a major multifactorial public health problem in French Guiana. Desert dust episodes have been associated with preterm delivery in Guadeloupe, a territory with similarities to French Guiana. We thus tried to replicate this finding in the context of French Guiana. A retrospective ecological cohort study combined daily PM10 concentration measurements during pregnancy and term at delivery extracted from French Guiana's computerized pregnancy delivery registry. Daily PM10 concentrations during the course of pregnancy were analyzed as mean concentrations and as the proportion of intense dust episodes (≥55 µg PM10/m3). These exposure variables were studied in relation to the outcome of preterm delivery. Overall, 3,321 pregnant women with complete daily PM10 measurements were included, of whom 374 (11.26%) delivered prematurely. Among preterm deliveries, 168 (44.9%) were spontaneous deliveries and 206 (55.1%) were induced. Rank-sum tests showed that, for spontaneous and induced spontaneous deliveries, both mean PM10 concentrations and proportions of intense desert dust episodes were significantly greater among preterm births than among term births. Although the proportion of intense desert dust episodes during pregnancy was significantly associated with spontaneous preterm deliveries, the relation was U-shaped, with an adjusted odds ratio (AOR) = 2 (95%CI = 1.2-3.1) for lowest values relative to median values and AOR = 5.4 (95%CI = 3.2-8.9) for the highest values relative to median values. Similarly, the proportion of intense desert dust episodes during pregnancy was also significantly associated with induced preterm deliveries in a U-shaped manner (AOR = 2.7 (95%CI = 1.6-4.5) for the lowest relative to median values and AOR = 6.8 (95%CI = 3.9-11.9) for the highest relative to median values). Although in our study the relation between PM10 concentrations appeared non-linear, the highest mean concentrations and intense desert dust episodes were indeed associated with both spontaneous and induced preterm delivery.

BACKGROUND: French Guiana is a French overseas territory which combines a well-funded universal health system and a population where half are under the poverty line. In this context, we aimed to measure and describe the causes of infant mortality and, because French Guiana is a French territory, to compare them with mainland France. METHODS: National death certificate data between 2001 and 2017 was used. RESULTS: Overall, 6.9 % of deaths before 65 years concerned infants <1 year (in mainland France 2.6%). The infant mortality rate over the 2001-2017 period was 2.6 times that of mainland France (1159.5 vs 446.2 per 100,000 infants <1 year) with excess incidence in perinatal causes, malformations and chromosomal anomalies, accidents, infectious causes, and in poorly defined conditions. Over time, there seemed to be a reduction of infant mortality for all the main causes, except for congenital malformations and chromosomal anomalies, which, on the contrary, seemed to increase. The data sources did not allow to study the weight of social factors or place of residence. CONCLUSIONS: All causes of infant mortality seemed to decline over time except malformations and chromosomal anomalies, which increased. Although exposure to heavy metals, infectious diseases are potential explanations we cannot pinpoint the cause of this increase with the available data. The present results suggest infant mortality and malformations should benefit from more detailed data sources in order to better assess and alleviate the burden of infant mortality in French Guiana.

Introduction: In a context of high HIV prevalence, poor pregnancy follow-up, frequent poverty, preeclampsia, and preterm delivery, we aimed to describe the characteristics and outcomes of pregnancies among women living with HIV in French Guiana. Methods: A retrospective cohort study was conducted on HIV-infected pregnancies enrolled between January 1st 1992 to 31st July 2022. Overall, there were 1,774 pregnancies in 881 women living with HIV. Results: For 75.1% of pregnancies, the HIV diagnosis was already known before pregnancy and in 67.6% of women, HIV follow-up predated pregnancy. Nearly half of women, 49.6%, only had one pregnancy since having been diagnosed with HIV. Although most women received antiretroviral therapy during pregnancy, for those with the available information we found only 48.5% had an undetectable viral load at delivery. Overall, 15.3% of pregnancies ended with an abortion. There were a total of 110 newborns infected with HIV representing an overall transmission rate of 6.2% (110/1,771). Between 1993 and 2002, the transmission rate was 34%, between 2003 and 2012 it was 1.3%, and between 2013 and 2022 it was 0.7%. Overall, in Cayenne, since 2008, 106 of 581 HIV-infected pregnancies (18.2%) with available information were premature before 37 weeks of pregnancy; of these, 33 (5.7%) were very preterm deliveries and 73 (13.3%) were late preterm deliveries. Over time, in Cayenne, preterm delivery declined significantly. Conclusions: The present study emphasizes that, despite spectacular progress in reducing mother to child transmission, pregnancy outcomes among women living with HIV are still preoccupying with high incidence of preterm delivery and low birth weight. Teasing out what fraction is linked to HIV and what fraction is linked to social precariousness and poor follow-up was not possible in this study. Despite the high incidence of very preterm delivery recent progress suggests that coordination efforts to improve follow-up may also have improved obstetrical outcomes.
RESUMO
A prospective study was conducted among different intra and extra-hospital populations of French Guiana to evaluate the performance of saliva testing compared to nasopharyngeal swabs. Persons aged 3 years and older with mild symptoms suggestive of COVID-19 and asymptomatic persons with a testing indication were prospectively enrolled. Nasopharyngeal and salivary samples were stored at 4°C before analysis. Both samples were analyzed with the same Real-time PCR amplification of E gene, N gene, and RdRp gene. Between July 22th and October 28th, 1159 persons were included, of which 1028 were analyzed. When only considering as positives those with 2 target genes with Ct values <35, the sensitivity of RT-PCR on saliva samples was 100% relative to nasopharyngeal samples. Specificity positive and negative predictive values were above 90%. Across a variety of cultures and socioeconomic conditions, saliva tests were generally much preferred to nasopharyngeal tests and persons seemed largely confident that they could self-sample. For positive patients defined as those with the amplification of 2 specific target genes with Ct values below 35, the sensitivity and specificity of RT-PCR on saliva samples was similar to nasopharyngeal samples despite the broad range of challenging circumstances in a tropical environment.

BACKGROUND: Hypertensive disorders of pregnancy (HDP) are responsible for high maternal mortality and morbidity worldwide. OBJECTIVE: Our primary objective was to report the epidemiological and clinical features of HDP in Cayenne General Hospital. Our secondary objectives were to search for factors associated to preeclampsia (PE) and to severe PE in patients with HDP. METHODS: Our study was observational and non-interventional. It was conducted over 4-month period (January to April 2019) in the Obstetrics and Gynaecology Unit of the Cayenne General Hospital. We included all pregnant women after 20 weeks of gestation (WG), who gave birth and who presented HDP and/or PE. RESULTS: During the study period 1243 patients gave birth in our unit. Among them, 156 were diagnosed with HDP (12.6%). The median age was 33 years (IQR 28 - 38 years). The most frequent medical histories were diabetes (27.5%) and chronic hypertension (23.5%). The socioeconomic status was low in 31% of patients. Ninety-four patients (61.4%) developed PE with a severe form in 80.9% of cases. HELLP syndrome was diagnosed in 6.5% and nephropathy in 3.3% of cases. Delivery was by cesarean in 49.7% of cases. The median gestational age at delivery was 37 WG (IQR: 35-39). Multivariate analysis showed no independent factors associated with the occurrence of PE or severe PE in patients with HDP. CONCLUSION: Our study shows a high prevalence of PE in patients with HDP. Hospitalization and repeated clinical evaluation are needed to screen for women exposed to develop PE or severe PE.
