A surface urban heat island (SUHI) is a phenomenon whereby temperatures in urban areas are significantly higher than that of surrounding rural and natural areas due to replacing natural and semi-natural areas with impervious surfaces. The phenomenon is evaluated through the SUHI intensity, which is the difference in temperatures between urban and non-urban areas. In this study, we assessed the spatial and temporal dynamics of SUHI in two urban areas of the French Guiana, namely Ile de Cayenne and Saint-Laurent du Maroni, for the year 2020 using MODIS-based gap-filled LST data...

BACKGROUND: Acute poisonings (AP) are a significant public health problem, accounting for a high number of emergency department visits and thousands of deaths worldwide. This study aimed to assess the epidemiology of AP in an adult population admitted to Cayenne Hospital (French Guiana) and to investigate the clinical and sociodemographic characteristics. METHODS: We conducted a monocentric retrospective study from January 2010 to December 2022, including patients over eighteen years of age who had been admitted to the emergency department of Cayenne Hospital for acute poisoning...

BACKGROUND: French Guiana (FG) is a French territory located in South America with the highest rate of armed assaults. FG presents a poorly developed road system and a young and precarious population that makes the geographical and socio-demographic characteristics specific. No data concerning the firearm injury management are available in this country. Studying thesis trauma could permit to improve the management of victims. The objective of this study is to investigate the epidemiology of firearm injuries in FG, to define characteristics of the victims, and to assess factors associated with death...

Pigmented purpuric dermatoses (PPD) encompass a group of chronic skin conditions characterized by the presence of petechiae, purpura, and pigmentation changes. While generally benign, these dermatoses can be persistent and aesthetically bothersome. Key clinical features include red to brownish patches with a distinctive "cayenne pepper" appearance, predominantly localized on the lower extremities, particularly the shins. Subtypes include Schamberg disease, Majocchi's disease, Gougerot-Blum disease, Ducas and Kapetanakis pigmented purpura, and lichen aureus...

In tropical countries, acute febrile illnesses represent a complex clinical problem for general practitioners. We describe the prevalence of different etiologies of acute febrile illnesses occurring among French service members and their families, excluding children, in general practice in French Guiana. From June 2017 to March 2020, patients with a fever ≥ 37.8°C with a duration of less than 15 days who sought medical care at the army medical centers in Cayenne and Kourou were prospectively enrolled...

Currently, the marketed ophthalmic preparations of pranoprofen (PF) are mainly eye drops, but due to the special clearance mechanism of the eye and corneal reflex, the contact time between the drug and the focal site is short, most of the drug is lost, and the bioavailability is less than 5%. In the present study, an in situ gel eye drop containing no bacteriostatic agent and sensitive to temperature and ions was designed for delivery of PF. It was demonstrated to meet the criteria for ophthalmic preparations by characterization such as appearance content sterility...

(1) Background: Until December 2021, French Guiana (FG), located in South America, faced four consecutive COVID-19 epidemic waves. This study sought to analyze the mortality trend of severe COVID-19 patients admitted to the referral ICU of FG. (2) Methods: We conducted a prospective, observational, and non-interventional study in ICU at Cayenne Hospital. We included 383 patients older than 18 admitted with SARS-CoV-2-related pneumonia hospitalized from May 2020 to December 2021. The study covers three periods...

Salmonella is a major foodborne pathogen and a leading cause of gastroenteritis in humans and animals. Salmonella is highly pathogenic and encompasses more than 2600 characterized serovars. The transmission of Salmonella to humans occurs through the farm-to-fork continuum and is commonly linked to the consumption of animal-derived food products. Among these sources, poultry and poultry products are primary contributors, followed by beef, pork, fish, and non-animal-derived food such as fruits and vegetables...

OBJECTIVES: Few small studies previously examined chest CT-scan characteristics of Coxiella burnetii (Cb) community-acquired pneumonia (CAP). Larger studies are needed to guide physicians towards diagnosis of Q fever in case of pneumonia. METHODS: We conducted a single-center retrospective observational study between 2013 and 2017. All patients with Cb or Sp CAP who had a chest CT-scan on admission at Cayenne Hospital (French Guiana) were included. Chest CT-scan were all analyzed by the same expert radiologist...

In 2020, food shortages occurred at the beginning of the confinement period that was supposed to curb the COVID-19 pandemic. In French Guiana, where a major part of the population lives under the poverty line, health workers voiced major concerns. Alongside massive food aid distributions, a first transversal study was carried out in August 2020 targeting poor neighborhoods in Cayenne. The results were particularly worrying. More than 80% of households had been suffering from hunger during that month, with a median decrease of 46% in revenue...

As sea levels are rising, the number of chronic flooding events at high tide is increasing across the world coastlines. Yet, many events reported so far either lack observational evidence of flooding, or relate to coastal areas where ground subsidence or oceanic processes often enhance climate change-induced sea-level rise (SLR). Here we present observational and modelling evidence of high-tide flooding events that are unlikely to occur without SLR in French Guiana, where sea-level rise rates are close to the global average and where there is no significant ground subsidence...

BACKGROUND: Strategies for the control of scabies should be adapted to local settings. Traditional communities in French Guiana have non-Western conceptions of disease and health. OBJECTIVES: The objectives for this study were to explore knowledge, attitudes and practices to identify potential factors associated with the failure of scabies treatment in these communities. METHODS: Patients with a clinical diagnosis of scabies, seen at either the Cayenne Hospital or one of 13 health centres between 01 April 2021 and 31 August 2021, were included as participants, and were seen again after 6 weeks to check for persistence of lesions...

PURPOSE: There is a significant amount of literature focusing on racial inequities in utilization rates and intraoperative complications of cataract surgery. Unfortunately, little is known about racial disparities regarding the timeline of cataract surgery and intraocular lens (IOL) selection. This study investigated whether black patients have a different preoperative and postoperative cataract surgery timeline and IOL selection than white patients. METHODS: A total of 10,235 patients (83...

Food dehydration is a preservation technique that guarantees its supply. Food like vegetables and fruits are traditionally dehydrated with natural gas or solar energy, however, this work demonstrates the feasibility of doing it with energy from a geothermal power plant in Nayarit, Mexico. Different species of pineapple (Miel, Cayenne, and Esmeralda) were dehydrated at different temperatures from 64 to 80°C and the safety of the product was subsequently verified, for these aerobic mesophiles (<230 ufc/g), total coliforms (<0...

INTRODUCTION: With over half of the population living under the poverty threshold, the social and health context in French Guiana is more difficult than in mainland France. The prevalence of diabetes is twice as great and end-stage renal failure is 45% higher than in mainland France. OBJECTIVE: Our objective was to describe the profile of diabetic patients with chronic kidney disease in French Guiana and search for possible risk factors. METHOD: We conducted a multicenter cross-sectional observational study based on the CODIAM cohort (Cohort of Diabetes in French Amazonia)...

Pineapple fruit, which is cultivated in tropical and subtropical areas, is processed by the food industry, generating a large amount of waste. Using pineapple by-products in animal nutrition could reduce feeding costs and contribute to the containment of pollution. The chemical composition and the in vitro fermentation of five pineapple by-products (crown, bud end, peel, core, and pomace) from two West African pineapple varieties (Smooth Cayenne-SC and Sugarloaf-SL) were evaluated. Significant differences were observed between the varieties and by-products...

The affinity of specific phenolic compounds (PCs) and capsaicinoids (CAPs) present in three Capsicum annuum varieties (Friariello, Cayenne and Dzuljunska Sipka) to the transient receptor potential vanilloid member 1 (TRPV1) was investigated by integrating an analytic approach for the simultaneous extraction and analysis through high-performance liquid chromatography coupled with ion trap mass spectrometry (HPLC/ITMS) and UV detection (HPLC-UV) of PCs and CAPs and structural bioinformatics based on the protein modelling and molecular simulations of protein-ligand docking...
