RESUMEN
Antimicrobial resistance (AMR) is a major global health threat estimated to have caused the deaths of 1.27 million people in 2019, which is more than HIV/AIDS and malaria deaths combined. AMR also has significant consequences on the global economy. If not properly addressed, AMR could immensely impact the world's economy, further increasing the poverty burden in low- and middle-income countries. To mitigate the risk of a post-antibiotic society, where the ability to effectively treat common bacterial infections is being severely threatened, it is necessary to establish a continuous supply of new and novel antibacterial medicines. However, there are gaps in the current pipeline that will prove difficult to address, given the time required to develop new agents. To understand the status of upstream antibiotic development and the challenges faced by drug developers in the early development stage, the World Health Organization has regularly assessed the preclinical and clinical antibacterial development pipeline. The review identifies potential new classes of antibiotics or novel mechanisms of action that can better address resistant bacterial strains. This proactive approach is necessary to stay ahead of evolving resistance patterns and to support the availability of effective treatment options. This review examines the trends in preclinical development and attempts to identify gaps and potential opportunities to overcome the numerous hurdles in the early stages of the antibacterial research and development space.

Objective: To explore the antimicrobial stewardship policy landscape in three English-speaking Caribbean countries (Barbados, Guyana, and Saint Lucia) and examine the key enablers and challenges to the design and implementation of formal antimicrobial stewardship programs. Methods: A document analysis that searched for existing policy, communications, and contributions on antimicrobial stewardship from these three countries, adapting the READ (Ready materials; Extract data; Analyze data; Distill findings) approach, a systematic procedure for health policy document review. Results: The search strategy identified 726 initial records. Of those, 15 (2%) met the inclusion criteria. The analysis included official policy documents (n = 3), scholarly works/reviews (n = 3), advocacy documents (n = 2), news articles (n = 4), and confidential reports (n = 3) from the three countries. Conclusions: Critical matters such as cross-programmatic coordination, the significance of individual action, and the need for bidirectional knowledge discourse are prominent in optimizing antimicrobial stewardship adaptation in these countries. CARICOM regional coordination has positively impacted the integration of infection prevention and control with antimicrobial stewardship across this knowledge network.
RESUMEN
Objective: To assess antibiotic use in three hospitals in three Caribbean countries based on data from 2013 and 2018 using the World Health Organization Essential Medicines List "Access, Watch, Reserve" (AWaRe) classification. Methods: A retrospective observational study, which analyzed the World Health Organization Point Prevalence Survey data from three hospitals in three Caribbean countries, to examine proportional AWaRe group antibiotic use for the top ten inpatient indications. The Access-to-Watch ratio was calculated, and the top three antibiotics prescribed in each hospital were determined. Results: The final data set included 376 prescriptions for the top ten indications in 766 inpatients. The hospital antibiotic use point prevalence for Hospital 1 was 35.6%, Hospital 2 was 48.6%, and Hospital 3 was 47.1%. The Access-to-Watch ratio for the top ten indications was 2.45, 1.36, and 1.72 in the three hospitals. Access group prevalence was 71.0% in Hospital 1, 57.6% in Hospital 2, and 63.2% in Hospital 3. There were no Reserve antibiotics prescribed in any of the institutions. The most common indication for Watch prescription was skin and soft tissue infections in Hospital 1 and pneumonia in Hospital 2 and 3. Conclusions: This study draws urgent attention to evidence of a high proportion of Watch antibiotic prescribing and lack of Reserve group antibiotics in three Caribbean countries. This research provides data that may inform national formulary and antimicrobial stewardship policy-making across the settings analyzed and the wider region.
RESUMEN
Psychogenic nonepileptic seizures, also called Functional Seizures, are a highly disabling form of Functional Neurological Disorder. The diagnosis of PNES could be missed in clinical scenarios where patients exhibit concurrent musculoskeletal/neurological findings. Characterization of convulsions and judicious use of diagnostics are equally valuable in establishing the diagnosis.

RESUMEN Objetivo. Explorar el panorama de las políticas de optimización del uso de antimicrobianos en tres países caribeños de habla inglesa (Barbados, Guyana y Santa Lucía) y examinar los principales facilitadores y desafíos para elaborar y aplicar programas formales de optimización del uso de antimicrobianos. Métodos. Se adaptó el método READ (acrónimo en inglés de "materiales listos; extraer los datos; analizar los datos; destilar los resultados"), un procedimiento sistemático para la revisión de documentos sobre políticas de salud, a fin de realizar un análisis de documentos que buscó las políticas, comunicaciones y contribuciones existentes sobre la optimización del uso de antimicrobianos en esos tres países. Resultados. La estrategia de búsqueda permitió localizar 726 documentos iniciales. De ellos, 15 (el 2%) cumplían los criterios de inclusión. El análisis abarcó documentos oficiales de políticas (n = 3), trabajos académicos o revisiones (n = 3), documentos de promoción de la causa (n = 2), artículos de noticias (n = 4) e informes confidenciales (n = 3) de los tres países. Conclusiones. Varios aspectos críticos, como la coordinación interprogramática, la importancia de la acción individual y la necesidad de una comunicación bidireccional del conocimiento, son preponderantes para adaptar de la mejor manera la optimización del uso de antimicrobianos en estos países. La coordinación regional de la CARICOM ha influido positivamente para integrar la prevención y el control de infecciones con la optimización del uso de antimicrobianos en toda esta red de conocimientos.

RESUMEN Objetivo. Evaluar el consumo de antibióticos en tres hospitales de tres países del Caribe según datos del período 2013-2018 mediante la clasificación de acceso, control y reserva (AWaRe, por su sigla en inglés) de la lista de medicamentos esenciales de la Organización Mundial de la Salud. Métodos. Se realizó un estudio observacional retrospectivo, que analizó los datos de la encuesta de prevalencia puntual de la Organización Mundial de la Salud de tres hospitales en tres países del Caribe, a fin de evaluar el consumo proporcional de antibióticos por grupo de la clasificación AWaRe para las diez principales indicaciones en pacientes hospitalizados. Se calculó la relación entre los grupos de acceso y de control y se determinó cuáles eran los tres principales antibióticos prescritos en cada hospital. Resultados. El conjunto final de datos incluyó 376 recetas para las diez indicaciones principales en 766 pacientes hospitalizados. La prevalencia puntual del consumo de antibióticos en el hospital 1 fue 35,6%, en el hospital 2 fue 48,6% y en el hospital 3 fue 47,1%. La relación entre los grupos de acceso y de control correspondientes a las diez principales indicaciones fue 2,45, 1,36 y 1,72 en los tres hospitales. La prevalencia del grupo de acceso fue 71,0% en el hospital 1, 57,6% en el hospital 2 y 63,2% en el hospital 3. No se prescribieron antibióticos del grupo de reserva en ninguna de las instituciones. La indicación más común para la prescripción de antibióticos en el grupo de control fue infecciones en la piel y los tejidos blandos en el hospital 1 y neumonía en los hospitales 2 y 3. Conclusiones. Este estudio busca llamar la atención urgentemente sobre la evidencia de una alta proporción de prescripción de antibióticos del grupo de control y la carencia de antibióticos del grupo de reserva en tres países del Caribe. Esta investigación proporciona datos que pueden fundamentar el formulario nacional y la elaboración de políticas para la optimización del uso de antimicrobianos en los entornos analizados y en la región en general.
RESUMO Objetivo. Avaliar o uso de antibióticos em três hospitais de três países do Caribe, com base em dados de 2013 e 2018, usando a classificação "Acesso, Vigilância e Reserva" (AWaRe) da Lista de Medicamentos Essenciais da Organização Mundial da Saúde. Métodos. Estudo observacional retrospectivo com análise de dados do Estudo de Prevalência Pontual da Organização Mundial da Saúde, coletados em três hospitais de três países do Caribe para examinar o uso proporcional de antibióticos dos grupos AWaRe para as dez indicações mais frequentes em pacientes internados. A razão entre os grupos Acesso e Vigilância foi calculada e determinou-se quais eram os três antibióticos mais prescritos em cada hospital. Resultados. O conjunto final de dados incluiu 376 medicamentos prescritos para as dez indicações mais frequentes em 766 pacientes internados. A prevalência pontual de uso de antibióticos foi de 35,6% no hospital 1, 48,6% no hospital 2 e 47,1% no hospital 3. A razão entre Acesso e Vigilância nas dez indicações mais frequentes foi 2,45, 1,36, e 1,72 nos três hospitais. A prevalência do grupo Acesso foi de 71,0% no hospital 1, 57,6% no hospital 2 e 63,2% no hospital 3. Nenhum antibiótico da categoria Reserva foi prescrito em nenhuma das instituições. A indicação mais comum dos medicamentos prescritos no grupo Vigilância foram infecções de pele e tecidos moles no hospital 1 e pneumonia nos hospitais 2 e 3. Conclusões. Este estudo chama urgentemente a atenção para evidências de uma grande proporção de antibióticos prescritos no grupo Vigilância e a carência de antibióticos do grupo Reserva em três países do Caribe. Esta pesquisa fornece dados que podem guiar a criação de políticas para o formulário terapêutico nacional e o uso racional de antimicrobianos nos cenários analisados e na região como um todo.
