RESUMEN

[ABSTRACT]. Objective. To identify challenges that may raise pathogens’ resistance to antimicrobial drugs by exploring the private market for antimicrobials in two selected mining and frontier areas of Guyana. Methods. The private sector supply was mapped by approaching all authorized pharmacies and informal outlets, e.g., street vendors and grocery stores, around the two selected towns. Interviews were conducted with a) sellers on the availability of drugs, expiration dates, prices, and main producers; and b) customers on purchased drugs, diagnoses, and prescriptions received before purchasing drugs, and intention to complete the treatment. The information collected was described, and the determinants of the self-reported intention of customers to complete the whole treatment were identified. Results. From the perspective of the supply of antimicrobials, essential medicines faced low and insecure availability, and prescriptions frequently deviated from diagnoses. From the perspective of the demand for antimicrobials, one-third of purchased antibiotics had a high potential for antimicrobial resistance as per the World Health Organization AWaRe classification. A high price reduced the self-reported intention to complete the treatment among those who had a prescription, while buying the medication in a licensed pharmacy increased such intention. Conclusions. In Guyana, there persists a need to establish and revise policies addressing both supply and demand, such as restricting the sale of antimicrobials to licensed pharmacies and upon prescription, improving prescription practices while reducing the financial burden to patients, guaranteeing access to first-line treatment drugs, and instructing patients on appropriate use of antimicrobials. Revising such policies is an essential step to contain antimicrobial resistance in the analyzed areas and across Guyana.

[RESUMEN]. Objetivo. Determinar los elementos que pueden aumentar la resistencia de los agentes patógenos a los medicamentos antimicrobianos mediante el examen del mercado privado de estos medicamentos en dos zonas mineras y fronterizas seleccionadas de Guyana. Métodos. Se elaboró un mapa de los suministros para el sector privado mediante una consulta a la totalidad de las farmacias autorizadas y a puntos de venta informales como vendedores ambulantes y tiendas de comestibles, en las dos ciudades seleccionadas. Se realizaron entrevistas con a) los vendedores (sobre la disponibilidad de medicamentos, fechas de caducidad, precios y fabricantes principales); y b) los clientes (sobre los medicamentos que habían comprado, los diagnósticos y las recetas que se les habían proporcionado antes de comprar los medicamentos, y sobre su intención de completar el tratamiento). Se describió la información recopilada y se determinaron los factores determinantes de la intención de completar el tratamiento manifestada por los clientes. Resultados. Desde el punto de vista de la oferta de antimicrobianos, la disponibilidad de medicamentos esenciales era escasa y no estaba garantizada y las prescripciones se apartaban con frecuencia de lo requerido por los diagnósticos. Desde el punto de vista de la demanda de antimicrobianos, un tercio de los antibióticos comercializados tenía un potencial alto de resistencia a los antimicrobianos según la clasificación AWaRe de la Organización Mundial de la Salud. Un precio elevado comportaba una reducción en la intención de completar el tratamiento, según lo manifestado por los pacientes que disponían de una receta, mientras que la compra del medicamento en una farmacia autorizada aumentaba esta intención. Conclusiones. En Guyana persiste la necesidad de implantar y actualizar una serie de políticas que aborden tanto la oferta como la demanda. Entre ellas se encuentran las de limitar la venta de antimicrobianos únicamente a las farmacias autorizadas y con receta médica, mejorar las prácticas de prescripción, y a la vez reducir la carga económica que suponen para los pacientes, garantizar el acceso a los medicamentos de primera línea, e instruir a los pacientes sobre el uso adecuado de los antimicrobianos. La actualización de estas políticas es un paso esencial para contener la resistencia a los antimicrobianos en las zonas analizadas y en toda Guyana.

[RESUMO]. Objetivo. Explorar o mercado privado de medicamentos antimicrobianos em duas áreas de mineração e de fronteira na Guiana para identificar os desafios que podem aumentar a resistência dos patógenos aos antimicrobianos. Métodos. Foram abordadas todas as farmácias autorizadas e pontos de venda informais, como vendedores ambulantes e mercearias, nas duas cidades selecionadas a fim de mapear a oferta do setor privado. Foram realizadas entrevistas com: a) vendedores (sobre disponibilidade, datas de validade, preços e principais produtores dos medicamentos); e b) clientes (sobre medicamentos comprados, diagnósticos, prescrições recebidas antes da compra dos medicamentos e a intenção de concluir o tratamento). As informações coletadas foram descritas e identificarem-se os determinantes da intenção declarada pelos clientes de concluir todo o tratamento. Resultados. Do ponto de vista da oferta de antimicrobianos, medicamentos essenciais tinham disponibilidade baixa e incerta, e as prescrições frequentemente divergiam dos diagnósticos. Com relação à demanda por antimicrobianos, um terço dos antibióticos comprados tinha alto potencial de resistência a antimicrobianos de acordo com a classificação AWaRe da Organização Mundial da Saúde. Preços elevados reduziam a intenção declarada de concluir o tratamento entre as pessoas que tinham prescrição, e a compra do medicamento em farmácias licenciadas aumentava essa intenção. Conclusões. Na Guiana, persiste a necessidade de estabelecer e revisar políticas que abordem tanto a oferta quanto a demanda, como: restringir a venda de antimicrobianos a farmácias licenciadas e mediante prescrição; melhorar as práticas de prescrição e, ao mesmo tempo, reduzir a carga financeira dos pacientes; garantir o acesso a medicamentos de primeira linha; e orientar os pacientes sobre o uso adequado de antimicrobianos. Revisar essas políticas é uma etapa essencial para conter a resistência a antimicrobianos nas áreas analisadas e no país inteiro.

RESUMEN

Background: Countries of the Caribbean Community signed the Declaration of Port of Spain in 2007 with the vision to stop the epidemic of non-communicable diseases (NCDs). The adoption of the Declaration by member states represented a regional effort, challenging governments, the private sector, and civil society to act together. Multisectoral actions in Guyana aimed at achieving this goal are the focus of this article, demonstrating the work of different actors in addressing the burden of NCDs in the country. Objective: To analyze multisectoral actions developed among five ministries for the implementation of the Declaration of Port of Spain 2007 in Guyana. Methods: This qualitative study was guided by the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist and conducted in five ministries (Agriculture, Education, Finance, Health, and Trade) in Georgetown, Guyana. The thematic analysis was guided by a framework consisting of four elements: context (why the policy is needed), content (what the policy is mainly about), process (how the policy was brought forward and implemented), and actors (who participates in and influences the formulation and implementation of the policy). The framework considers how these elements interconnect to shape policy development and implementation processes. Findings: Data analysis provided the researchers with insights into possible topic areas and codes for consideration during the analysis, hence a deductive approach to data analysis was used. The results highlighted the importance of coordination among government entities, national and international agencies, private actors, industry players, and civil society. Participants did not mention the use of responsibility metrics but cited mechanisms that facilitated collaboration. Conclusion: The results showed limitations in transforming multisectoral initiatives into intersectoral collaboration to achieve real integration among the different actors involved, considering the actual context and content. Actions could be more effectively implemented with significant outcomes for NCD control in Guyana.

RESUMEN

Several countries of the Guiana Shield are aiming at the control and elimination of malaria in areas where Artisanal and Small-scale Gold Mining (ASGM) activities predominate, raising questions about how to strengthen community engagement to improve the effectiveness of health programs. The Curema project focuses its intervention on the mobile and hard-to-reach ASGM population, complementing the efforts of national programs in the Guiana Shield. The Curema intervention combines targeted drug administration for suspected Plasmodium vivax asymptomatic carriers, the Malakit distribution, and health education activities. The primary goals of this manuscript are to outline a pathway to foster community participation in the Curema project aimed at eliminating malaria. Thus, it presents a vision of the challenges that the AGSM community poses in terms of community participation for an asymptomatic problem; and highlights the community-based model and the Information, Education and Communication (IEC) components as foundations for participation. In addition, it also presents culturally sensitive IEC strategies designed through iterative and collaborative consultative processes and other bottom-up outreach activities. The community engagement approach facilitates adaptability and responsiveness in a complex, evolving context increasing the effectiveness of interventions.

RESUMEN

OBJECTIVE: The objective was to describe the social, environmental, and cultural adaptations to an existing falls program and assess acceptability and preliminary effectiveness of the program in reducing fear, reducing falls, and improving function among individuals poststroke in Guyana. METHODS: A quasi-experimental pilot study with a pretest/posttest in-group design was developed through a collaboration of researchers in Guyana and the US. Participants took part in the falls prevention program for 8 weeks. Outcome measures included a 10-m walk test, the Five Times Sit to Stand Test, and subjective questionnaires for falls incidence and balance confidence at the beginning and end. RESULTS: Twenty participants completed the study. One participant experienced medical complications, and their data were excluded from analysis. Fifteen participants (78.9%) demonstrated improvements in comfortable and fast walking speed. Twelve participants completed the Five Times Sit to Stand Test. Eleven (91.67%) improved their time at the posttest, with 9 (81.8%) demonstrating a clinically important improvement. Nineteen participants had sustained at least 1 fall prior to the study. Only 1 participant reported a fall during the program. Initially, the majority of participants (11/19) were very concerned about falling. At the end, only 1 was very concerned about falling, and the majority (15/19) were not concerned at all. Posttest surveys of participants indicated acceptability of the program. CONCLUSIONS: This pilot program helped reduce fall risk and improve confidence, gait speed, and community mobility of the study participants. Future research at other rehabilitation departments in Guyana would help increase the generalizability of the program. IMPACT: The program can be used clinically by physical therapists in Guyana, both in departments and as a home program. Shared knowledge and experience of researchers considering research evidence and the environmental, social, and economic conditions of people living in Guyana were important in developing an effective program.

RESUMEN

BACKGROUND: Although limited, there is some evidence that certain physical punishments may vary by household religion. OBJECTIVE: This study aimed to determine whether parent disciplinary behavior varies by religious affiliation in two countries which have large, diverse religious groups. PARTICIPANTS AND SETTING: Data from Multiple Indicator Cluster Surveys for Suriname (2018) and Guyana (2019-20), which contain nationally representative household samples, were used. The study was restricted to the three most prevalent religious groups: Christians, Hindus, and Muslims. METHODS: Adult responses to a standardized survey that included questions about use of disciplinary behaviors in the household towards children (aged 1-14 years) were examined in relation to religious affiliation of the head-of-household and multiple covariates. RESULTS: Of the 3518 Suriname households, 62.4 %, 23.3 % and 14.3 % were Christians, Hindus, and Muslims, respectively. Compared to Christians, children in both Hindu and Muslim households had significantly lower odds of being hit with an object in adjusted logistic regression models. However, only Hindus had lower odds of being spanked and Muslims lower odds of exposure to a combined physical and non-physical practice, compared to Christians. Of the 2535 Guyana households, 69.5 %, 23.5 % and 7.0 % were Christians, Hindus, and Muslims, respectively. Children in Hindu, but not Muslim households, had significantly lower odds of being spanked, hit with an object, and exposed to a combine practice in adjusted models compared to Christians. CONCLUSIONS: Partial support was found for a potential influence of religion on some disciplinary behaviors. Further investigation is warranted to identify possible conditions and mechanisms.

RESUMEN

Species of the ectomycorrhizal (ECM) family Cortinariaceae (Agaricales, Agaricomycetes, Basidiomycota) have long been considered impoverished or absent from lowland tropical rainforests. Several decades of collecting in forests dominated by ECM trees in South America's Guiana Shield is countering this view, with discovery of numerous Cortinariaceae species. To date, ~12 morphospecies of this family have been found in the central Pakaraima Mountains of Guyana. Here, we describe three of these as new species of Cortinarius and two as new species of Phlegmacium from forests dominated by the ECM tree genera Dicymbe (Fabaceae subfam. Detarioideae), Aldina (Fabaceae subfam. Papilionoideae), and Pakaraimaea (Cistaceae). Macromorphological, micromorphological, habitat, and DNA sequence data are provided for each new species.

RESUMEN

Countries within the tropics face ongoing challenges in completing or updating their national forest inventories (NFIs), critical for estimating aboveground biomass (AGB) and for forest-related greenhouse gas (GHG) accounting. While previous studies have explored the integration of map information with local reference data to fill in data gaps, limited attention has been given to the specific challenges presented by the clustered plot designs frequently employed by NFIs when combined with remote sensing-based biomass map units. This research addresses these complexities by conducting four country case-studies, encompassing a variety of NFI characteristics within a range of AGB densities. Examining four country case-studies (Peru, Guyana, Tanzania, Mozambique), we assess the potential of European Space Agency's Climate Change Initiative (CCI) global biomass maps to increase precision in (sub)national AGB estimates. We compare a baseline approach using NFI field-based data with a model-assisted scenario incorporating a locally calibrated CCI biomass map as auxiliary information. The original CCI biomass maps systematically underestimate AGB in three of the four countries at both the country and stratum level, with particularly weak agreement at finer map resolution. However, after calibration with country-specific NFI data, stratum and country-level AGB estimates from the model-assisted scenario align well with those obtained solely from field-based data and official country reports. Introducing maps as a source of auxiliary information fairly increased the precision of stratum and country-wise AGB estimates, offering greater confidence in estimating AGB for GHG reporting purposes. Considering the challenges tropical countries face with implementing their NFIs, it is sensible to explore the potential benefits of biomass maps for climate change reporting mechanisms across biomes. While country-specific NFI design assumptions guided our model-assisted inference strategies, this study also uncovers transferable insights from the application of global biomass maps with NFI data, providing valuable lessons for climate research and policy communities.

RESUMEN

Plasmodium parasites, the causal agents of malaria, are eukaryotic organisms that obligately undergo sexual recombination within mosquitoes. In low transmission settings, parasites recombine with themselves, and the clonal lineage is propagated rather than broken up by outcrossing. We investigated whether stochastic/neutral factors drive the persistence and abundance of Plasmodium falciparum clonal lineages in Guyana, a country with relatively low malaria transmission, but the only setting in the Americas in which an important artemisinin resistance mutation (pfk13 C580Y) has been observed. We performed whole genome sequencing on 1,727 Plasmodium falciparum samples collected from infected patients across a five-year period (2016-2021). We characterized the relatedness between each pair of monoclonal infections (n = 1,409) through estimation of identity-by-descent (IBD) and also typed each sample for known or candidate drug resistance mutations. A total of 160 multi-isolate clones (mean IBD ≥ 0.90) were circulating in Guyana during the study period, comprising 13 highly related clusters (mean IBD ≥ 0.40). In the five-year study period, we observed a decrease in frequency of a mutation associated with artemisinin partner drug (piperaquine) resistance (pfcrt C350R) and limited co-occurence of pfcrt C350R with duplications of plasmepsin 2/3, an epistatic interaction associated with piperaquine resistance. We additionally observed 61 nonsynonymous substitutions that increased markedly in frequency over the study period as well as a novel pfk13 mutation (G718S). However, P. falciparum clonal dynamics in Guyana appear to be largely driven by stochastic factors, in contrast to other geographic regions, given that clones carrying drug resistance polymorphisms do not demonstrate enhanced persistence or higher abundance than clones carrying polymorphisms of comparable frequency that are unrelated to resistance. The use of multiple artemisinin combination therapies in Guyana may have contributed to the disappearance of the pfk13 C580Y mutation.

RESUMEN

Fish stocks have declined rapidly over the past half-century due to the increased demand for seafood and unsustainable fishing practices. The incidental capture of non-target species (bycatch) is a pervasive issue in fisheries management and has led to population declines in non-target species worldwide. The fisheries sector in Guyana currently supports the livelihoods of over 10,000 Guyanese and contributes approximately 2% to the country's GDP. Bycatch is believed to be a major threat to Guyana's marine fisheries, especially the small-scale sector, due to a lack of management infrastructure and limited data and monitoring. Here, we assessed bycatch in Guyana's artisanal gillnet and Chinese seine fisheries through vessel observations and semi-structured interviews with local fishers. Most of the discarded species documented had no commercial importance to the fisheries in Guyana. Although no statistical difference was observed among the bycatch rates in the gillnet and Chinese seine fisheries, the latter generally had more discarded individuals, most of which were juveniles. The Shannon-Weiner diversity index showed a greater diversity of bycatch species in the gillnet fisheries compared to the Chinese seine. Jaccard's similarity index indicated a low similarity among the gear types. Even though most fishers were aware of bycatch, they did not view it as a major issue and were not interested in reducing their discards. We recommend a collaborative approach in exploring solutions to ensure the ecological and socioeconomic sustainability of the fisheries sector.

RESUMEN

BACKGROUND: To assess the attitudes of women towards intimate partner violence (IPV) in Guyana. METHODS: We used national data from the publicly available Multiple Indicator Cluster Survey (MICS) conducted in Guyana in 2019 for women aged 15 to 49 years. The prevalence of women who agreed that a husband is justified in beating his wife was analyzed. Respondent reasons included if she: "goes out without telling him", "neglects the children", "argues with him", "refuses sex with him", "burns the food", "has another partner", "stays out late/partying", "refuses to cook or clean", "overspends", and/or "he doesn't have access to her cellphone". Descriptive analyses were carried for all the variables. Logistic regression was used to identify factors associated with these 10 respondent reasons, separately and in combination. RESULTS: The overall prevalence of women's attitudes justifying IPV against women if there was a 'yes' response to any of the 10 reasons was 17.9% (95%CI: 16.6-19.3%), and varied from 2.7% if she "goes out without telling him", "burns the food", or "overspends" to 10.0% if she "has another partner". This prevalence ranged from 10.2% in urban areas to 19.3% in rural areas (p<0.001), and from 16.1% in coastal to 30.1% in interior areas (p<0.001). Similarly, 25.9% of women from the poorest household agreed that a husband has the right in beating his wife for any of the 10 reasons compared to 11.6% of the richest women (11.6%) (p<0.001). Rural place of residence, ethnicity, geographic region, level of education, wealth quintile, ever used of a computer, and frequency of listening to the radio were significant factors associated with women's attitudes justifying IPV against women (p<0.05). CONCLUSION: Over one-sixth of the respondents agreed that a husband was justified in committing IPV against women in Guyana. Public health programs focusing on geographic locations, ethnicity, and economic status must be implemented to change attitudes justifying IPV and reduce this significant public health challenge.

RESUMEN

The consumption of primates is integral to the traditional subsistence strategies of many Indigenous communities throughout Amazonia. Understanding the overall health of primates harvested for food in the region is critical to Indigenous food security and thus, these communities are highly invested in long-term primate population health. Here, we describe the establishment of a surveillance comanagement program among the Waiwai, an Indigenous community in the Konashen Amerindian Protected Area (KAPA). To assess primate health in the KAPA, hunters performed field necropsies on primates harvested for food and tissues collected from these individuals were analyzed using histopathology. From 2015 to 2019, hunters conducted 127 necropsies across seven species of primates. Of this sample, 82 primates (between 2015 and 2017) were submitted for histopathological screening. Our histopathology data revealed that KAPA primates had little evidence of underlying disease. Of the tissue abnormalities observed, the majority were either due to diet (e.g., hepatocellular pigment), degenerative changes resulting from aging (e.g., interstitial nephritis, myocyte lipofusion), or nonspecific responses to antigenic stimulation (renal and splenic lymphoid hyperplasia). In our sample, 7.32% of individuals had abnormalities that were consistent with a viral etiology, including myocarditis and hepatitis. Internal parasites were observed in 53.66% of individuals and is consistent with what would be expected from a free-ranging primate population. This study represents the importance of baseline data for long-term monitoring of primate populations hunted for food. More broadly, this research begins to close a critical gap in zoonotic disease risk related to primate harvesting in Amazonia, while also demonstrating the benefits of partnering with Indigenous hunters and leveraging hunting practices in disease surveillance and primate population health assessment.

RESUMEN

Mayaro virus (MAYV) is a mosquito-borne Alphavirus that is widespread in South America. MAYV infection often presents with non-specific febrile symptoms but may progress to debilitating chronic arthritis or arthralgia. Despite the pandemic threat of MAYV, its true distribution remains unknown. The objective of this study was to clarify the geographic distribution of MAYV using an established risk mapping framework. This consisted of generating evidence consensus scores for MAYV presence, modeling the potential distribution of MAYV in select countries across Central and South America, and estimating the population residing in areas suitable for MAYV transmission. We compiled a georeferenced compendium of MAYV occurrence in humans, animals, and arthropods. Based on an established evidence consensus framework, we integrated multiple information sources to assess the total evidence supporting ongoing transmission of MAYV within each country in our study region. We then developed high resolution maps of the disease's estimated distribution using a boosted regression tree approach. Models were developed using nine climatic and environmental covariates that are related to the MAYV transmission cycle. Using the output of our boosted regression tree models, we estimated the total population living in regions suitable for MAYV transmission. The evidence consensus scores revealed high or very high evidence of MAYV transmission in several countries including Brazil (especially the states of Mato Grosso and Goiás), Venezuela, Peru, Trinidad and Tobago, and French Guiana. According to the boosted regression tree models, a substantial region of South America is suitable for MAYV transmission, including north and central Brazil, French Guiana, and Suriname. Some regions (e.g., Guyana) with only moderate evidence of known transmission were identified as highly suitable for MAYV. We estimate that approximately 58.9 million people (95% CI: 21.4-100.4) in Central and South America live in areas that may be suitable for MAYV transmission, including 46.2 million people (95% CI: 17.6-68.9) in Brazil. Our results may assist in prioritizing high-risk areas for vector control, human disease surveillance and ecological studies.

RESUMEN

Preventing vector-borne diseases (VBDs) mainly relies on effective vector control tools and strategies, which in turn depend on population acceptance and adherence. Inspired by the abundant recent literature on SARS-COV-2, we investigate the relationship between risk perception and preventive behaviour for selected VBDs and the extent to which risk perception is determined by social norms. We use cross-sectional data collected from 497 individuals in four regions of Guyana in 2017. We use a conditional mixed process estimator with multilevel coefficients, estimated through a Generalized Linear Model (GLM) framework, applying a simultaneous equation structure. We find robust results on malaria: risk perception was significantly influenced by the risk perception of the reference group across different definitions of the reference group, hinting at the existence of social norms. Risk perception significantly increased the likelihood of passive behaviour by 4.48%. Less clear-cut results were found for dengue. This study applies quantitative social science methods to public health issues in the context of VBDs. Our findings point to the relevance of tailoring communications on health risks for VBDs to groups defined at the intersection of socio-economic and demographic characteristics. Such tailored strategies are expected to align risk perception among reference groups and boost preventive behaviour.

RESUMEN

Guyana's colonial past has left a trail of economic instability, racial polarization, and physical and mental trauma. Despite the progress made since Guyana's independence in 1966, the remnants of this colonial past continue to shape present-day Guyana. As a result, violence and trauma continue to impact the mental health of the population. This is manifest in endemic problems of domestic violence and racialized social divisions which have created the conditions for rates of suicide which are amongst the highest in the world. The formal mental health provision which exists in Guyana is based primarily on an individualized and largely biomedical model of care. Despite valuable attempts to develop this provision, the difficulty of physically accessing this for some people and the stigma which surround this means that the capacity of this system to address the serious problems which exist is limited. It is also the case that in times of emotional and psychic distress, and in the context of Guyana being a very religious country, many people turn to traditional supernatural healers and remedies for support. In this paper, we discuss what is known as "Obeah", noting that while this is widely practiced, it remains something of a taboo subject in Guyana. We consider the reasons why these practices and beliefs continue to be influential. However, what neither these biomedical or supernatural perceptions of mental health are able to address is the sociogenic nature of Guyana's mental health issues, which we argue emerges out of the historic trauma of Guyana's experience of colonialism and the violence which it engendered. We argue that profound forms of mental distress which exist in Guyana call for an integrative and holistic practice model that contextualizes these problems through a sociogenic lens. Social workers, working collaboratively with other health-related professions, can occupy a critical role in integrating these different conceptions through developing a rights-based model of mental health where the causes of mental ill-health are understood as socially determined.

RESUMEN

Seed dispersal is widely considered an important mechanism for the conservation of plant diversity. In tropical regions, over 80% of woody plant species are dispersed by vertebrates, often through the consumption of fruits. Our understanding of what drives interactions between vertebrates and fruits is limited. Through a systematic literature search, we compiled a database of fruit and seed traits and vertebrate-fruit interactions for tree and vertebrate species occurring in the Guianas, with the aim of facilitating research into seed dispersal and seed predation of tree species in the Guianas. The database was compiled by extracting data from 264 published sources. It consists of 21,082 records, of which 19,039 records contain information about 19 different fruit and seed traits belonging to 1622 different tree species. The other 2043 records contain information on vertebrate-fruit interactions between 161 vertebrate species and 464 tree species. Our analyses showed a taxonomic bias, particularly in the interaction data, toward large-bodied vertebrates, with most interactions recorded for the bearded saki (Chiropotes chiropotes), followed by the lowland tapir (Tapirus terrestris). For plants we found an overrepresentation of the Sapotaceae and Moraceae families and an underrepresentation of the Rubiaceae, Myrtaceae, and Lauraceae families in the interactions. There are no copyright restrictions on the data set; please cite this publication when using these data.

RESUMEN

This study examined the mediating role of parental cognitive engagement and parental guidance on the associations between family socioeconomic and home environment resource risk factors and children's literacy and social skills in Guyana. The sample consisted of 1208 families from diverse ethnic and socioeconomic backgrounds drawn from the 2019 to 2020 country-level UNICEF MICS data. Caregivers provided assessments of socioeconomic conditions, educational resources in the home environment, cognitive engagement, parental guidance and children's literacy and social skills. Family socioeconomic risk had an indirect association with social skills through cognitive engagement. Home environment educational resource risk had indirect associations with children's literacy and social skills through parental guidance. Findings are discussed in terms of identifying protective factors within families in low- and middle-income Caribbean countries that can better inform intervention efforts geared at reducing risks to childhood development.

RESUMEN

The actual diversity of anurans occurring in Amazonia remains only partly described. This is notably the case of the species of the genus Allobates despite a fast rate of species description in this genus during the last decade. This increasing taxonomic effort has been particularly facilitated by the availability of DNA sequences throughout the region. These data suggest for instance the existence of three lineages in the Guiana Shield that may correspond to unnamed species. We examined morphology and calls of these putative species and compared them to related nominal species, which confirmed that two of these lineages not only differ genetically but also morphologically and bioacoustically. These two species are thus named and described herein. Allobates vicinus sp. nov. from northern Suriname forms a clade with another candidate species from southern Suriname and Northern Pará, (Brazil) and with A. granti that occurs in French Guiana. Allobates ripicolus sp. nov. occurs throughout the eastern Guiana Shield and is nested within the A. tapajos complex which otherwise occurs in southeastern Amazonia and comprises A. tapajos and A. kamilae, along with three additional candidate species.
