Dengue fever is an important public health problem in Jamaica and has various serious manifestations, which if not identified and treated at the appropriate time can lead to dire consequences. Bacterial co-infections have been seen in clinical practice but may be thought of as simply coincidental. This review highlights the importance of bacteria in exacerbating dengue infections and the importance of looking for co-infection in patients with certain clinical manifestations. It also provides the reader with a scientific understanding of the immune pathogenesis of dengue and bacterial co-infections.

Background: Antimicrobial resistance (AMR) is a critical global health challenge, linked to 4·71 million deaths in 2021 and affecting human health, animals, food, plants, and the environment. This scoping review aims to map out published interventions addressing AMR in the Latin America and Caribbean (LAC) region. Methods: We searched PubMed, Web of Science, LILACS, and grey literature for articles reporting the implementation of AMR programs, interventions, or policies aimed at tackling AMR published between January 2018 and December 2024. Results: A total of 82 studies were included, comprising 64 peer-reviewed articles and 18 from grey literature. The majority ( n = 75) focused on human health, while a smaller subset ( n = 7) addressed animal health. Geographically, most studies were conducted in Brazil ( n = 32) and Colombia ( n = 22) with only one study in the Caribbean. Antimicrobial stewardship interventions were the primary focus in 50 studies. Only 53 out of 74 studies included an evaluation of the intervention. Conclusion: Significant gaps remain in AMR research in LAC, particularly in animal and environmental health. Rigorous intervention evaluations are needed to generate high-quality evidence for policy and practice. Increased funding for intervention and implementation research across all sectors is crucial to tackling AMR regionally and globally.

An antimicrobial consumption (AMC) study was performed in Trinidad and Tobago at the Eastern Regional Health Authority (ERHA). A retrospective, cross-sectional survey was conducted from 1 November 2021 to 30 March 2022. Dosage and package types of amoxicillin, azithromycin, co-amoxiclav, cefuroxime, ciprofloxacin, levofloxacin, moxifloxacin, nitrofurantoin and co-trimoxazole were investigated. Consumption was measured using the World Health Organization’s Antimicrobial Resistance and Consumption Surveillance System methodology version 1.0, as defined daily doses (DDD) per 1000 population per day (DID). They were also analyzed using the ‘Access’, ‘Watch’ and ‘Reserve’ classifications. In the ERHA, AMC ranged from 6.9 DID to 4.6 DID. With regards to intravenous formulations, the ‘Watch’ group displayed increased consumption, from 0.160 DID in 2017 to 0.238 DID in 2019, followed by a subsequent drop in consumption with the onset of the COVID-19 pandemic. Oral co-amoxiclav, oral cefuroxime, oral azithromycin and oral co-trimoxazole were the most highly consumed antibiotics. The hospital started off as the higher consumer of antibiotics, but this changed to the community. The consumption of ‘Watch’ group antibiotics increased from 2017 to 2021, with a drop in consumption of ‘Access’ antibiotics and at the onset of COVID-19. Consumption of oral azithromycin was higher in 2021 than 2020.

Antimicrobial resistance (AMR) represents a major threat to health with significant global economic and safety implications. One of the major drives of this resistance is the misuse and overuse of antimicrobials. Background/Objectives: In this sense, WHO proposed to it members to estimate the antimicrobial consumption (AMC) at each country level, in order to help local authorities in their decision making related to AMR control. Although this program is already installed worldwide, in the American continent, the rate of countries’ inclusion has been delayed. This paper describes the efforts of Latin American & Caribbean countries in terms of AMC local assessment. Methods: AMC data collection was done as per the GLASS tool proposed by WHO. Analysis was performed using Daily Defined Dose each one thousand inhabitants day (DID) for global, therapeutical group or each antibiotic. Access, Watch and target Reserve (AWaRe) WHO classification was applied after data collection. Results: 13 countries were included during the period 2019–2022. The global DID ranged from 2.55 DID to 36.26 DID. The trend of this consumption did downward along the years. One of the factors than impacted the AMC was the COVID-19 pandemic. The most problematic antimicrobial misuse was seen in certain beta lactams and macrolides, like ceftriaxone and azithromycin. Regarding the AWaRe classification, 5 out of 13 countries accomplished the target until 2023 of 60% consumption for “Access antimicrobial’s group by 2023). This data helped local health managers to propose changes for better control of the AMR problem (ceftriaxone usage limitations in Peru, antimicrobial law in Argentina, etc.). Conclusions: The first steps towards AMC country’s assessment has been initiated. The present work provided essential inputs to local health authorities for decision making related to AMR control. It will be necessary to keep applying this results in regulate antibiotic usage at country level, as well as enrolling more countries in the AMC project.

The authors report a fatal case of Corynebacterium sp. endocarditis. Corynebacterium spp. are non-sporulating, pleomorphic Gram-positive bacilli. In particular the authors have identified a species of Corynebacterium very closely related to C striatum. This is C simulans. The authors were able to identify the genus and species using various phenotypic tests. Highlighted here is the importance of identifying diphtheroids as a significant pathogen in the appropriate setting and the need to start antibiotic therapy if this is suspected.

The inappropriate consumption, use, and dispensing of antibiotics are problems faced globally, with a pattern of inappropriate consumption differing in higher-income countries due to the ease of accessibility of antibiotics. The main drivers of consumption and inappropriate use are the over-the-counter sales of antibiotics by pharmacies. Trinidad and Tobago (T&T), a twin island state in the Caribbean, has two Acts of Parliament that regulate antibiotics: the Antibiotics Act and the Food and Drug Act, yet the Over-the-Counter (OTC) sale of antibiotics still exists. This study sought to determine the knowledge, attitudes, and practices regarding the OTC dispensing of antibiotics in T&T. A cross-sectional study gathered data from pharmacists in both the private and public sectors of Trinidad over 7 months. The results showed that antibiotic resistance and antibiotic abuse were seen as significant problems. The level of experience, gender (female), and age (younger) were significantly associated with having good overall knowledge of good dispensing habits and antibiotic laws (p = 0.036, p = 0.047, and p = 0.001, respectively). Pharmacists generally agreed that antibiotics under the Food and Drug Act may have contributed to OTC dispensing in the private sector (p = 0.013) and that all antibiotics should be under the Antibiotic Act (p = 0.002). Additionally, it was found that the dispensing of antibiotics OTC in the private sector (p = 0.006) occurred: without doctors’ advice and without requesting prescriptions; because it was perceived as lawful (especially by older pharmacists); and because of the perceived motivation of profit. Regulation enforcement was perceived as deficient. OTC dispensing for reasons, such as misunderstanding of laws, occurs in T&T.
