Front-of-package food labelling (FOPL) is a mechanism to inform consumers on food nutrients content and risks for health. Each country, within its own institutional framework, defines methods and protocols to formulate rules capable of influencing organizations and the behavior of agents. The paper aims at evaluating the role of some meso-institutions in shaping arenas for policymaking on FOPL based on an exploratory study in Brazil, Chile, and Mexico. A documental analysis and literature review were employed, followed by in-depth interviews. The relevant aspects of FOPL assessed were thresholds for sugar, fats, and sodium; marketing restrictions, and timeframe given for compliance with the new rules. The contribution of this article is to illuminate the way in which meso-institutions operate in a specific context, namely the development of food labelling standards. The focus is to find the rules that allowed the participation of stakeholders in the process of defining normative acts intended to regulate food labelling. The discussion of mandatory FOPL can be interpreted as a struggle to define proper rights for the food industry and the consumer. Meso-institutions, as translators of general normative principles in specific contexts, can encourage or restrict stakeholder participation in policymaking. Besides political arena, the participation can be done in other arenas, such as legislature, regulatory agencies, scientific community, media and public opinion. Institutions that encourage stakeholder participation increase the probability of obtaining widely accepted specific rules. [ABSTRACT FROM AUTHOR]

Understanding how emerging infectious diseases spread within and between countries is essential to contain future pandemics. Spread to new areas requires connectivity between one or more sources and a suitable local environment, but how these two factors interact at different stages of disease emergence remains largely unknown. Further, no analytical framework exists to examine their roles. Here we develop a dynamic modelling approach for infectious diseases that explicitly models both connectivity via human movement and environmental suitability interactions. We apply it to better understand recently observed (1995-2019) patterns as well as predict past unobserved (1983-2000) and future (2020-2039) spread of dengue in Mexico and Brazil. We find that these models can accurately reconstruct long-term spread pathways, determine historical origins, and identify specific routes of invasion. We find early dengue invasion is more heavily influenced by environmental factors, resulting in patchy non-contiguous spread, while short and long-distance connectivity becomes more important in later stages. Our results have immediate practical applications for forecasting and containing the spread of dengue and emergence of new serotypes. Given current and future trends in human mobility, climate, and zoonotic spillover, understanding the interplay between connectivity and environmental suitability will be increasingly necessary to contain emerging and re-emerging pathogens. Here, using a dynamic modelling approach, the authors find that the spread of dengue through Mexico and Brazil is shaped by specific interactions between human mobility, climate, and the environment. Their models can also be applied to predict future spread in these geographic areas. [ABSTRACT FROM AUTHOR]

Background: During the coronavirus disease 2019 (COVID-19) pandemic, in patients treated for SARS-CoV-2 infection, infections with the Klebsiella pneumoniae bacteria producing New Delhi metallo-B-lactamase (NDM) carbapenemase in the USA, Brazil, Mexico, and Italy were observed, especially in intensive care units (ICUs). This study aimed to assess the impact of Klebsiella pneumoniae NDM infection and other bacterial infections on mortality in patients treated in ICUs due to COVID-19. Methods: The 160 patients who qualified for the study were hospitalized in ICUs due to COVID-19. Three groups were distinguished: patients with COVID-19 infection only (N = 72), patients with COVID-19 infection and infection caused by Klebsiella pneumoniae NDM (N = 30), and patients with COVID-19 infection and infection of bacterial etiology other than Klebsiella pneumoniae NDM (N = 58). Mortality in the groups and chosen demographic data; biochemical parameters analyzed on days 1, 3, 5, and 7; comorbidities; and ICU scores were analyzed. Results: Bacterial infection, including with Klebsiella pneumoniae NDM type, did not elevate mortality rates. In the group of patients who survived the acute phase of COVID-19 the prolonged survival time was demonstrated: the median overall survival time was 13 days in the NDM bacterial infection group, 14 days in the other bacterial infection group, and 7 days in the COVID-19 only group. Comparing the COVID-19 with NDM infection and COVID-19 only groups, the adjusted model estimated a statistically significant hazard ratio of 0.28 (p = 0.002). Multivariate analysis revealed that age, APACHE II score, and CRP were predictors of mortality in all the patient groups. Conclusion: In patients treated for SARS-CoV-2 infection acquiring a bacterial infection due to prolonged hospitalization associated with the treatment of COVID-19 did not elevate mortality rates. The data suggests that in severe COVID-19 patients who survived beyond the first week of hospitalization, bacterial infections, particularly Klebsiella pneumoniae NDM, do not significantly impact mortality. Multivariate analysis revealed that age, APACHE II score, and CRP were predictors of mortality in all the patient groups. [ABSTRACT FROM AUTHOR]

The genus Trogolaphysa comprises 81 described species distributed across the Neotropical and Afrotropical regions. In the Americas, just over half of the species found in subterranean habitats have a reduced eye number (0–5 eyes). Subterranean species are of interest as models to study the evolution of morphological adaptations. Many subterranean species of Trogolaphysa were described before the introduction of chaetotaxy as a diagnostic tool and thus remain incompletely described and diagnosed. To identify gaps in descriptions and facilitate the identification of newly collected forms, we provide standardized summary descriptions, species diagnoses, diagnostic tables, and a dichotomous key to the 33 Neotropical species of Trogolaphysa with reduced eye number. As a result of this synthesis, we describe two new troglobiontic species, Trogolaphysa reneaui n. sp. and Trogolaphysa welchi n. sp. from Belizean caves. [ABSTRACT FROM AUTHOR]

A scientometric analysis of the Neotropical Otter is essential to establish the progress in studies with the species, in order to improve its conservation status. This study aimed to identify, categorize, and evaluate published scientific papers on Lontra longicaudis. Quantitative data was analyzed through absolute and relative frequencies, represented by tables and maps. The results showed that the publications on the Neotropical Otter increased since 1993 and have been primarily published in a specific journal (IUCN Otter Spec. Group Bull.) on the subfamily Lutrinae. Most authors reside in countries such as Brazil, Mexico, and Colombia, and publish predominantly in English. The majority of studies were conducted with free-living specimens, notably in the Brazilian state of Rio Grande do Sul and in Mexico. The most commonly used keywords match the most frequent subjects: "place of occurrence" and "diet". Despite the increase in publications, research on the Neotropical Otter is still largely limited to Brazil, Mexico, and sites near research institutions. Gaps on essential information for the species conservation, such as its biology, ecology, and behavior, were identified. The need for further studies on the Neotropical Otter in all the territory it inhabits is evident.
