Levers and Barriers to Vaccinate against COVID-19 in the Multicultural Context of French Guiana: A Qualitative Cross-Sectional Survey among Health Care Workers.

In French Guiana, a French overseas territory in South America facing a fourth wave of COVID-19, vaccination coverage is very low, both in the population and among health care workers (HCWs). Vaccine hesitancy concerned 35.7% of the latter in early 2021. The objective of this complementary study is to understand barriers and levers and to adapt messages to increase vaccination coverage among HCWs. We conducted a regional cross-sectional survey of HCWs with a questionnaire containing open-ended questions exploring factors associated with vaccine hesitancy and the needs to adapt the vaccination campaign in French Guiana. The discourses were analyzed using a qualitative approach based on grounded theory, with open coding of data by themes and construction of abstract categories. The analysis of the 357 responses collected from January to March 2021 reveals several trends. The ethical aspect of the HCWs' role emphasizes the importance of getting vaccinated themselves (to protect patients, to set an example...) and of vaccinating as many people as possible, including the most geographically or socially distant, such as undocumented migrants. However, some HCWs remain suspicious of the vaccine with concerns over the efficacy and side effects, of health institutions, and of the pharmaceutical industry. The role of fake news circulating on social networks has been widely discussed. Efforts to explain and convince HCWs must be continued in French Guiana using the identified levers to improve the acceptability of vaccination.

Attitudes towards the COVID-19 Vaccine and Willingness to Get Vaccinated among Healthcare Workers in French Guiana: The Influence of Geographical Origin.

Background: In the context of the global COVID-19 pandemic and the expansion of the more transmissible 20J/501Y.V3 (Gamma) variant of concern (VOC), mRNA vaccines have been made available in French Guiana, an overseas French territory in South America, from mid-January 2021. This study aimed to estimate the willingness to be vaccinated and the socio-demographic and motivational correlates among Health Care Workers (HCWs) in French Guiana. Methods: A cross-sectional survey was conducted from January 22 to March 26, 2021 among a sample of HCWs in French Guiana. They were asked about their willingness to get vaccinated against COVID-19 and vaccine hesitancy, vaccine uptake and vaccines attitudes. Factors associated with willingness to get vaccinated have been analyzed with ordinal logistic regression, using Stata software. Results: A total of 579 HCWs were interviewed, including 220 physicians and 200 nurses most often working in hospital (54%) or in the liberal sector (22%). Overall, 65.6% of respondents reported that they were willing or had already been vaccinated against COVID-19, while 24.3% of respondents reported that they did not want to get vaccinated against COVID-19 and 11.2% were unsure. HCWs were more willing to get vaccine if they were older, were worried about COVID-19 and were confident in the management of epidemic. Conversely, participants were less likely to have been vaccinated or willing to if they were nurses or of another non-medical profession, born in French Guiana, feared adverse effects, or if they did not trust pharmaceutical companies and management of the epidemic by authorities. Conclusion: Negative attitudes towards vaccines are a major public health concern among HCWs in French Guiana when considering the current active epidemic with Gamma VOC. General vaccine hesitancy and concerns about future side effects in particular represent important barriers. Low confidence in government and science are significant in COVID-19 vaccine refusal among non-medical staffs. Public health messaging with information on vaccine safety should be tailored to address these concerns. The specific challenges of HCWs from French Guiana must be taken into account.

INTRODUCTION: The western French Guiana hospital (Chog) is atypical. The creation of a public health department (PSP) is the result of a willingness of the institution to respond to public health issues on its territory. The main objective of this article is to identify the levers and impediments for the development of public health activities within this hospital, after five years of implementation. METHOD: This article was based on the analysis of documents produced within the PSP, the institution and at the regional level (2013-2018), and on interviews conducted in 2017 with PSP professionals, and chiefs of other departments of the Chog (N = 16). RESULTS: The added value of the PSP is based on the pooling of human resources and technical skills, the coexistence of clinical activities, prevention, research, teaching and international cooperation with Suriname, and the development of multidisciplinary and evaluative approaches. The lack of a set of public health objectives in the establishment project, the lack of place for these activities in its new hospital, and the difficult mobilization of financial resources, however, limit the prospects. CONCLUSION: This analysis has shown difficulties in developing public health activities within this hospital, in an overseas territory with nonetheless multiple and complex needs. The authors invite politics and health authorities to value, and develop these activities, conditions necessary for the positioning of the hospital as an actor of the “turn in prevention”.

High prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae in Western French Guiana

ABSTRACT The purpose of this study was to estimate the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections in western French Guiana and to analyze associated factors with both infections. A retrospective study was conducted in a sexually transmitted infections clinic in 2017. Women (n = 338) were tested by real-time polymerase chain reaction for vaginal, anal and throat CT and NG infections. Men (n = 192) were evaluated using urine specimens. Socio-demographic and sexual behaviour data were collected by nurses with a structured questionnaire. The prevalence of CT and NG infections among women were 24.3% and 13.3%, respectively, and 12.0% and 7.3% among men. Women aged under 25 years had a higher risk of CT and NG infections than women aged 35 years or more. Another risk factor for CT infection was low educational level, and occasional unprotected sex for NG infection. CT and NG infections were associated with reporting symptoms among men. Very high prevalences of CT and NG infections among women and men were found, which suggest that a large-scale screening strategy should be implemented in French Guiana.

Reintervention after thoracic endovascular aortic repair of complicated aortic dissection.

OBJECTIVE: This study assessed predictive factors for reintervention after thoracic endovascular aortic repair (TEVAR) for complicated aortic dissection (C-AD). METHODS: An institutional review of consecutive TEVAR for C-AD was performed. RESULTS: Between 2000 and 2011, 41 patients underwent TEVAR for a C-AD involving the descending thoracic aorta. Primary indications included aneurysm >55 mm in 24, rapid aneurysmal enlargement or impending rupture in 6, saccular aneurysm >20 mm in 1, malperfusion in 1, intractable chest pain in 3, and rupture in 6. Technical success was achieved in 100%. The 30-day mortality rate was 5% (n = 2). Fourteen secondary procedures were performed in 13 patients (32%) for indications of device migration in 2, proximal type I endoleak in 5, distal type I endoleak in 2, type II endoleak in 1, aneurysmal evolution of the descending thoracic aorta in 2, aneurysmal expansion of the dissected abdominal aorta in 1, and retrograde dissection in 1. Multivariate analysis demonstrated that oversizing ≥20% (odds ratio [OR], 16; P = .011), bare-spring stent in the proximal landing zone of the stent graft (OR, 12; P = .032), and anticoagulant therapy (OR, 78; P = .03) were significant factors for reintervention. On univariate analysis, large aneurysm was a risk factor for reintervention (P = .002), whereas complete false lumen thrombosis at the stent graft level was protective (P < .05). CONCLUSIONS: This study confirms the feasibility of TEVAR for C-AD, although the rate of reintervention is high. Excessive oversizing, a bare-spring stent graft in the proximal landing zone, large aortic dilatation, and anticoagulant therapy were factors associated with reintervention. Complete false lumen thrombosis at the stent graft level was protective.
