RESUMEN

Molossuspretiosus is a molossid bat that has been thought to exist in Honduras. While some authors have suggested its range extends all the way to Mexico, others have placed its northernmost distribution in Nicaragua. We present evidence, based on one specimen collected in 2005, confirming the presence of this species in the Caribbean of Honduras within the Islas de la Bahía department. This discovery increases the count of known species within this family to 18 in the country and raises the total bat species count for Honduras to 114. We recommend a detailed study of historical specimens to confirm the identification of species that may have been misidentified as well as a thorough examination of molossids distributed in northern Honduras.

RESUMEN

Background: A growing body of evidence points to potential risks associated with polypharmacy (using ≥5 medications) in older adults, but most evidence is derived from studies where racial and ethnic minorities remain underrepresented among research participants. Objective: Investigate the association between polypharmacy and cognitive function, subjective health state, frailty, and falls in Hispanic older adults. Methods: Panama Aging Research Initiative-Health Disparities (PARI-HD) is a community-based cohort study of older adults free of dementia at baseline. Cognitive function was measured with a neuropsychological test battery. Frailty assessment was based on the Fried criteria. Subjective health state and falls were self-reported. Linear and multinomial logistic regression analyses were used to examine association. Results: Baseline evaluations of 468 individuals with a mean age of 69.9 years (SD = 6.8) were included. The median number of medications was 2 (IQR: 1-4); the rate of polypharmacy was 19.7% (95% confidence interval [CI] = 16.1-23.3). Polypharmacy was inversely associated with self-rated overall health (b =-5.89, p < 0.01). Polypharmacy users had 2.3 times higher odds of reporting two or more falls in the previous 12 months (odds ratio [OR] = 2.31, 95% CI = 1.06-5.04). Polypharmacy was independently associated with Fried's criteria for pre-frailty (OR = 2.90, 95% CI = 1.36-5.96) and frailty (OR = 5.14, 95% CI = 1.83-14.42). Polypharmacy was not associated with cognitive impairment. Conclusions: These findings illustrate the potential risks associated with polypharmacy among older adults in Panama and may inform interventions to improve health outcomes in this population.

RESUMEN

The Americas contain highly biodiverse yet vulnerable ecosystems, with many threatened species inadequately protected. Finer-scale, localized habitat assessments are crucial for effective conservation planning, but continental-scale high-resolution vegetation maps remain limited. This study addresses this gap by identifying critical vegetation types across the Americas using the standardized framework of the International Vegetation Classification (IVC) system at the macrogroup level, representing the finest vegetation classification available across the region, as well as the highest-resolution Area of Habitat (AOH) maps currently available. By combining these high-resolution IVC macrogroup maps with detailed AOH maps, we highlight at-risk vegetation types based on 1) threatened and macrogroup-associated species (species that have at least 50% of their AOH in one macrogroup), 2) current protection levels, and 3) projected threats from land use changes, and 4) develop a conservation value index (CVI) that accounts for all these factors. The results highlighted the remarkable diversity of high conservation value macrogroups across the Americas, emphasizing their significance in regions such as the Andes, montane Mesoamerica, the Caribbean, Brazil's Cerrado, and the Atlantic Forest. Among the highest-scoring macrogroups, the Northern Andean Montane & Upper Montane Humid Forest emerged as critically important, harboring a high number of threatened and macrogroup-associated species. Other macrogroups of immediate conservation concern include the Brazilian Atlantic Montane Humid Forest, Pacific Mesoamerican Seasonal Dry Forest, Caribbean Lowland Humid Forest, and Central Midwest Oak Forest, Woodland and Savanna. However, the study revealed that nearly three-quarters of the over 300 macrogroups in the Americas fall below the global target of 30% protection. Notably, a fifth of all species were macrogroup-associated species, including over 40% of threatened species. Our findings emphasize the need for targeted conservation strategies that consider finer-scale habitat classifications and paired with high-quality species distribution data to guide conservation strategies for biodiversity across the Americas.


Las Américas contienen ecosistemas altamente biodiversos pero vulnerables, con muchas especies amenazadas insuficientemente protegidas. Las evaluaciones de hábitat hechas a escala más detallada son cruciales para una planificación eficaz de la conservación, pero los mapas de vegetación de alta resolución a escala continental siguen siendo limitados. Este estudio aborda esta brecha, identificando tipos de vegetación críticos en las Américas utilizando el marco estandarizado del sistema de Clasificación Internacional de Vegetación (IVC) a nivel de macrogrupo, que representa la clasificación de vegetación más detallada disponible en toda la región, así como los mapas de Área de Hábitat (AOH) de mayor resolución disponibles en la actualidad Al combinar estos mapas de IVC de alta resolución con mapas de AOH, determinamos los tipos de vegetación en riesgo basados ​​en 1) especies amenazadas y asociadas a macrogrupos (especies que tienen al menos el 50% de su AOH en un macrogrupo), 2) niveles de protección de las especies, y 3) amenazas proyectadas por cambios en el uso del suelo , y 4) desarrollar un índice de valor de conservación (CVI) que tenga en cuenta los tres factores anteriores. Los resultados demuestran la notable diversidad de macrogrupos de alto valor de conservación en las Américas, enfatizando su importancia en regiones como los Andes, la Mesoamérica montañosa, el Caribe, el Cerrado de Brasil y el Bosque Atlántico. Entre los macrogrupos con mayor puntuación, el Bosque Húmedo Montano Norte Andino y Alto Montano emergieron como de importancia crítica, ya que albergan un gran número de especies amenazadas y asociadas a macrogrupos. Otros macrogrupos de interés para la conservación incluyen el Bosque Húmedo Montano Atlántico de Brasil, el Bosque Seco Estacional Mesoamericano del Pacífico, el Bosque Húmedo de Tierras Bajas del Caribe y el Bosque de Robles, Bosques y Sabanas del Medio Oeste Central. Sin embargo, el estudio reveló que casi tres cuartas partes de los más de 300 macrogrupos en las Américas se encuentran por debajo del objetivo global del 30% de protección. En particular, una quinta parte de todas las especies estaban asociadas a un único   macrogrupo, incluidas más del 40% de especies amenazadas. Nuestros hallazgos enfatizan la necesidad de estrategias de conservación específicas que consideren clasificaciones de hábitats a escala detallada y se combinen con datos de distribución de especies de alta resolución para guiar las estrategias de conservación de la biodiversidad en las Américas.


As Américas abrigam ecossistemas altamente biodiversos, porém vulneráveis, com muitas espécies ameaçadas insuficientemente protegidas. Avaliações de habitat em escalas mais detalhadas são cruciais para um planejamento eficaz de conservação, mas mapas de vegetação de alta resolução em escala continental ainda são limitados. Este estudo aborda essa lacuna, identificando tipos críticos de vegetação nas Américas usando o quadro padronizado do sistema de Classificação Internacional de Vegetação (IVC) no nível de macrogrupo, que representa a classificação de vegetação mais detalhada disponível em toda a região, bem como os mapas de Área de Hábitat (AOH) de maior resolução disponíveis atualmente. Ao combinar esses mapas de IVC de alta resolução com mapas de AOH, determinamos os tipos de vegetação em risco com base em 1) espécies ameaçadas e associadas a macrogrupos (espécies que têm pelo menos 50% de sua AOH em um macrogrupo), 2) níveis de proteção das espécies, e 3) ameaças projetadas por mudanças no uso do solo, e 4) desenvolvemos um índice de valor de conservação (CVI) que leva em consideração os três fatores anteriores. Os resultados demonstram a notável diversidade de macrogrupos de alto valor de conservação nas Américas, enfatizando sua importância em regiões como os Andes, a Mesoamérica montanhosa, o Caribe, o Cerrado do Brasil e a Mata Atlântica. Entre os macrogrupos com maior pontuação, o Bosque Úmido Montano Norte Andino e Alto Montano emergiram como de importância crítica, abrigando um grande número de espécies ameaçadas e associadas a macrogrupos. Outros macrogrupos de interesse para a conservação incluem o Bosque Úmido Montano Atlântico do Brasil, o Bosque Seco Estacional Mesoamericano do Pacífico, o Bosque Úmido de Terras Baixas do Caribe e o Bosque de Carvalhos, Florestas e Savanas do Centro-Oeste Central. No entanto, o estudo revelou que quase três quartos dos mais de 300 macrogrupos nas Américas estão abaixo da meta global de 30% de proteção. Em particular, um quinto de todas as espécies estava associado a um único macrogrupo, incluindo mais de 40% das espécies ameaçadas. Nossas descobertas enfatizam a necessidade de estratégias de conservação específicas que considerem classificações de habitats em escala detalhada e se combinem com dados de distribuição de espécies de alta resolução para orientar as estratégias de conservação da biodiversidade nas Américas.

RESUMEN

Background: Atopic dermatitis (AD) is an inflammatory skin condition, often multifactorial in origin, and most commonly manifests during childhood. Although there remains a deficit in literature, current data suggest Honduras may have the highest prevalence and severity of AD among all Latin American countries. Objective: To assess the current prevalence of pediatric AD in Honduras and evaluate existing gaps in available literature to monitor disease burden. Methods: A comprehensive literature search was performed in March 2023. Articles were removed if they were published before 2007, were of the incorrect study design, or were focused on countries outside of Honduras. The articles were independently reviewed by 2 authors. Results: The initial literature search yielded 174 studies, of which 7 met inclusion criteria. AD prevalence rates in children in Honduras ranged from 0.7% to 40.0%. Limitations: Limitations include elements of study design, analytic methods, study populations, and limited articles. Conclusion: There appears to be a disproportionately higher prevalence and disease burden of pediatric AD in Honduras. Future research should acquire accurate data to further understand the prevalence, incidence, and severity of AD in Honduras.

RESUMEN

During a molecular screening of rickettsial, borrelial and protozoal agents in ticks from rural areas of Panama, we detected DNA of Rickettsia amblyommatis in four Amblyomma mixtum collected from horses in a locality in Los Santos province. Ehrlichia minasensis and Anaplasma marginale were identified from three and two Rhipicephalus microplus, respectively, collected on cows from Chiriqui province. No DNA from other tick-borne agents was found. These results increase the information of R. amblyommatis and A. marginale in Panama, and also mark the first record of E. minasensis in Central America.

RESUMEN

BACKGROUND: Dry eye is one of the most common ophthalmic conditions and can significantly impact quality of life. Meibomian gland dysfunction (MGD) is a major cause of evaporative dry eye. We sought to conduct a systematic review and meta-analysis to estimate the prevalence and incidence of dry eye and MGD in Central and South America and to identify factors associated with disease burden. METHODS: Data sources Ovid MEDLINE and Embase. STUDY SELECTION: A search conducted on August 16, 2021, identified studies published between January 1, 2010, and August 16, 2021, with no restrictions regarding participant age or language of publication. Case reports, case series, case-control studies, and interventional studies were excluded. DATA EXTRACTION AND SYNTHESIS: The review was based on a protocol registered on PROSPERO (CRD42021256934). Risk of bias was assessed in duplicate using a risk of bias tool designed for the purposes of descriptive epidemiological studies. Data were extracted by one investigator and verified by another for accuracy. Prevalence of dry eye and MGD were grouped based on study participant characteristics. MAIN OUTCOMES AND MEASURES: Prevalence and incidence of dry eye and MGD in Central and South America. Summary estimates from meta-analysis with 95% confidence intervals (CI). RESULTS: Fourteen studies (11,594 total participants) were included. The population prevalence of dry eye was 13% (95% CI, 12%-14%) in Brazil and 41% (95% CI, 39%-44%) in Mexico based on one study each. Meta-analyses suggested that dry eye prevalence was 70% among indoor workers (95% CI, 56%-80%; I2, 82%; 3 studies), 71% among students (95% CI, 65%-77%; I2, 92%; 3 studies), and 83% in general ophthalmology clinics (95% CI, 77%-88%; I2, 88%; 2 studies). MGD prevalence ranged from 23% among indoor workers (95% CI, 16%-31%; 1 study) to 68% in general ophthalmology clinics (95% CI, 62%-72%; 1 study). No studies reported incidence of dry eye or MGD. CONCLUSIONS: This systematic review and meta-analysis demonstrated considerable variation in the published prevalence of dry eye and MGD among the general population and subpopulations in Central and South America. Local and subpopulation estimates of dry eye disease burden may be valuable to assist needs assessments and implementation of measures to mitigate the condition.

RESUMEN

OBJECTIVES: We discuss key health challenges currently faced by countries in the Central America and Dominican Republic region after the COVID-19 pandemic. We highlight the influence of socioeconomic determinants for the challenging public health dynamics observed and the crucial roles that regional cooperation and health economic research can have for tackling such challenges. METHODS: We present a descriptive overview of the current situation of public finances and its effect on government capacity to improve social expenditure. We also discuss the impact of the COVID-19 pandemic crisis on social dynamics and living conditions in the region. RESULTS: Our analysis suggests that the interplay between all these factors is likely to have important consequences for health systems and population health in the post-pandemic period. Previous examples of successful cross-country cooperation in the region indicate the great potential that these initiatives have for supporting health system resilience against current challenges. Technical cooperation must be informed by (currently unavailable) research evidence that can guide decision making, especially health economic research to support national health resource allocation policies. Areas identified as priorities for applied health economic research include both macro and microeconomic analyses. CONCLUSIONS: Central America and the Dominican Republic face significant health challenges post-pandemic. Our article emphasizes the great potential that regional technical cooperation, informed by further health economic research, has to improve public policies and health governance in the region.

RESUMEN

OBJECTIVES: The aim of this study is to report on the frequency of serious physical injuries (SPI) among adolescents in Central America during the previous decade, 2009-2018. METHODS: In total, 15,807 school adolescents (14.4 years mean age; SD=1.4) from six Central American countries participated in cross-sectional Global School-based Student Health Surveys in 2009-2018 (ranging from 1,779 students in Honduras in 2012 to 4,374 students in Guatemala in 2015). RESULTS: The prevalence of SPI was 33.8 % (22.9 % once, 7.4 % 2 or 3 times and 3.6 % 4 or more times), ranging from 31.8 % in Guatemala to 45.0 % in Belize and 45.6 % in Panama. The most frequent causes of SPI included fall (11.4 %, ranging from 6.9 % in Costa Rica to 15.6 % in Panama), and the type of SPI was fracture/dislocation (5.7 %, ranging from 4.3 % in Costa Rica to 6.7 % in Panama). In adjusted Poisson regression, male sex, food insecurity, a history of alcohol intoxication, soft drink consumption, fast food intake, truancy, multiple sexual partners, psychological distress, physical fight, physically attacked, bullied, and suicide attempt were significantly associated with a higher number of injury event counts. CONCLUSIONS: Overall, about one in three adolescents in Central America had sustained unintentional injuries in the past 12 months and several contributing factors were identified which if addressed could aid injury prevention among adolescents.

RESUMEN

Molecular genetic analyses of Caribbean populations of the supposedly widespread intertidal oribatid mite Alismobates inexpectatus revealed the existence of a cryptic species. The new species, Alismobates piratus sp. n., shows considerable COI and 18S rRNA gene sequence divergences and although morphometric analyses indicate considerable variation between the taxa, no distinguishing morphological feature could be detected. The extreme intertidal environment is suggested to be responsible for the observed morphological stasis of the two species and vicariance is supposed to be responsible for their speciation. Alismobates piratus sp. n. was found on Hispaniola, Guadeloupe, Barbados and Curaçao indicating a predominant distribution on the Greater and Lesser Antilles, whereas the occurrence of A. inexpectatus is primarily restricted to Central America, the northern Caribbean and the Greater Antilles. Haplotype network analyses indicate distinct geographic structuring and the absence of recent gene flow among the Antillean A. piratus sp. n. populations. Central American and Antillean populations of A. inexpectatus show similar patterns but populations from Bermuda and the Bahamas are characterized by a common origin and subsequent expansion. Genetic landscape analysis demonstrates that vast stretches of open ocean, like the Caribbean Basin and the Western Atlantic, act as rather effective barriers, whereas the continuous continental coastline of Central and North America may facilitate dispersal. Genetic data also indicates that the Gulf Stream plays an important role for the biogeography of intertidal oribatid mites as it may be responsible for the strong link between Central and North American populations as well as for the colonization of Bermuda. Supplementary Information: The online version contains supplementary material available at 10.1007/s13127-023-00624-9.

RESUMEN

Introducción: Los estudios de coral negro en Centroamérica son escasos. No se ha publicado nada sobre las especies, hábitats, distribución e importancia del coral negro de El Salvador. A pesar de que Antipathes ha sido reportado como uno de los géneros de coral que ha sucumbido a la presión antrópica. Objetivos: Identificar las especies de corales negros en Los Cóbanos, El Salvador, y caracterizar cualitativamente la abundancia y el tamaño de las colonias; e identificar las especies epibiontes más conspicuas en las colonias. Métodos: Se realizó censo visual con buceo para la caracterización cualitativa y fotografías submarinas para el registro de especies epibiontes en seis puntos de Los Cóbanos, entre diciembre de 2021 y febrero de 2022, asimismo para caracterizar tamaño de las colonias y abundancia. Resultados: Se realizo el primer informe de bosques de coral negro en El Salvador, construidos por dos especies: Myriopathes panamensis y Antipathes galapagensis. También, reportamos por primera vez la presencia de M. panamensis, Pacifigorgia senta, Heterogorgia verrucosa, Eugorgia mutabilis, Nemathus californicus y Amphiodia sp. Encontramos afectaciones de origen antrópico, como desechos marinos y daños a las colonias por anclas. Conclusiones: Es necesario establecer esfuerzos para conocer la fauna de la zona mesofótica, principalmente en ecosistemas marinos vulnerables de bosques de coral negro y jardines de gorgonias. Existe un potencial importante, y los datos ayudarán a superar las brechas de información en la región, permitiendo mejores medidas de conservación.


Introduction: Black coral studies in Central America are scarce. Even though Antipathes has been reported as one of the coral genera that has succumbed to anthropic pressure, publications haven't been made on El Salvador black coral species, habitats, distribution, and importance. Objective: To identify the species of black corals in Los Cóbanos, El Salvador, and qualitatively characterize the abundance and size of the colonies; and to identify the most conspicuous epibiont species in the colonies. Methods: Visual census with SCUBA diving for qualitative characterization and underwater photographs were taken for the registration of epibiont species in six points of Los Cóbanos, between December 2021 to February 2022 and six to characterize size of the colonies and abundance. Results: The first report of black coral forests in El Salvador was made, constructed by two species: Myriopathes panamensis and Antipathes galapagensis. We also reported, for first time, the occurrence of M. panamensis, Pacifigorgia senta, Heterogorgia verrucosa, Eugorgia mutabilis, Nemathus californicus and Amphiodia sp. We found disturbances of anthropic origin, such as marine debris and damage to the colonies by anchors. Conclusions: It is necessary to establish efforts towards the knowledge of the fauna of mesophotic zones, mainly in vulnerable marine ecosystems of black coral forests and gorgonian gardens. There is an important potential, and data will help overcome information gaps in the region, allowing for better conservation measures.

RESUMEN

RESUMEN Las redes de tráfico humano para la prostitución captan a menores vulnerables, en especial, a quienes consideran no les queda otra opción que emigrar al norte para hacer frente a problemas económicos graves. El objetivo del presente trabajo fue establecer si el orden de nacimiento representó un factor de riesgo, asociado a la vulnerabilidad para la trata sexual de menores centroamericanas, traficadas a Estados Unidos. Las entrevistadas mostraban vulnerabilidades vinculadas con estructuras sociales y conductas individuales. Por una parte, todas crecieron en hogares caracterizados por la pobreza extrema. Por otra parte, también presentaban vulnerabilidades relacionadas con el embarazo adolescente, la falta de educación, la disfuncionalidad familiar y la participación en mercados ilegales. Ocupar el primer lugar en orden de nacimiento eleva la vulnerabilidad de las menores a ser traficadas a Estados Unidos para el comercio sexual. Por el contrario, ocupar el último lugar disminuye este riesgo.


ABSTRACT Human trafficking networks for prostitution recruit vulnerable underage girls, especially those who are considered with no choice but to migrate north to cope with serious economic problems. The aim of this work was to determine if birth order represented a risk factor associated to the vulnerability for sex trafficking of Central American female minors. The interviewees presented vulnerabilities associated to social structures and individual behaviors. On the one hand, all of them grew up in house holds characterized by extreme poverty. On the other hand, they also had vulnerabilities related to teenage pregnancy, lack of education, family dysfunction and participation in illegal markets. Findings suggest that occupying the first place in the order of birth raises the vulnerability of minors to being trafficked to the United States for sex trade. On the contrary, occupying the last place decreases this risk.

RESUMEN

BACKGROUND: The worldwide increase in the prevalence and incidence of sleep disturbances represents a major public health issue. Among multiple determinants affecting sleep health, an individual's socioeconomic status (SES) is the most ignored and underestimated throughout the literature. No systematic review on the relation between SES and sleep health has been previously conducted in Latin America. METHODS: PRISMA guidelines were used. RESULTS: Twenty articles were included in the final sample (all cross-sectional studies), and twelve among them were rated as fair or poor quality. Among these studies, 80.0% (n = 16) were performed in Brazil, 10.0% (n = 2) were performed in Peru, 5.0% (n = 1) were performed in Chile, and 5.0% (n = 1) were multicentric (11 countries). The combined total number of participants was N = 128.455, comprising 3.7% (n = 4693) children, 16.0% (n = 20,586) adolescents, and 80.3% (n = 103,176) adults. The results show the following: (1) The sleep outcomes analyzed were sleep duration, sleep quality/sleep disturbance, insomnia, excessive daytime sleepiness (EDS), obstructive sleep apnea (OSA)/sleep-disordered breathing (SDB) symptoms, and bruxism. (2) The most used determinants were income, education level, employment status/occupation, wealth/assets, and composite indices. (3) Higher SES was associated with shorter sleep duration. (4) Lower SES was associated with a decrease in sleep quality, less frequent snoring, more prevalent EDS, and sleep bruxism. (5) Lower education was associated with insomnia. (6) Higher education was associated with more sleep bruxism. (7) The pooled prevalence using a meta-analysis of the random effects model was 24.73% (95%CI, 19.98-30.19), with high heterogeneity (I2 = 100%). (8) The prevalence of sleep disturbances decreased with high education (OR, 0.83; 95%CI, [0.69-0.99]; I2 = 79%), while it increased with low income (OR, 1.26; 95%CI, [1.12-1.42]; I2 = 59%), unemployment (OR, 2.84; 95%CI, [2.14-3.76]; I2 = 0%), and being a housewife (OR, 1.72; 95%CI, [1.19-2.48]; I2 = 55%). DISCUSSION: This meta-analysis shows that lower SES (education, income, and work) was associated with sleep disturbances in Latin America. Therefore, sleep disturbance management should be addressed with a multidimensional approach, and a significant investment in targeted public health programs to reduce sleep disparities and support research should be made by the government before the situation becomes uncontrollable.

RESUMEN

BACKGROUND: Psychosocial and physical trauma are known risk factors for irritable bowel syndrome (IBS), including in war veterans, whereas war exposure in civilians is unclear. Nicaragua experienced two wars, 1970-1990: The Sandinistas Revolution (1970s) and The Contra War (1980s). Our aim was to investigate the role of exposure to war trauma in the subsequent development of IBS in the context of an established health surveillance system (11000 households). AIM: To investigate in a civilian population the relationship between exposure to war trauma and events and the subsequent development of IBS in the context of an established public health and demographic surveillance system in western Nicaragua. METHODS: We conducted a nested population-based, cross-sectional study focused on functional gastrointestinal disorders based on Rome II criteria. 1617 adults were randomly selected. The Spanish Rome II Modular Questionnaire and Harvard Trauma Questionnaire were validated in Nicaragua. War exposure was assessed with 10 measures of direct and indirect war trauma and post-war effects. Multiple exposures were defined by ≥ 3 measures. RESULTS: The prevalence of IBS was 15.2% [Female (F) 17.1%, Male (M) 12.0%], war exposure 19.3% (F 9.3%, M 36.7%), and post-traumatic stress disorder (PTSD) 5.6% (F 6.4%, M 4.3%). Significant associations with IBS in the civilian population were observed (adjusted by gender, age, socioeconomic status, education): physical and psychological abuse [adjusted odds ratio (aOR): 2.25; 95% confidence interval: 1.1-4.5], witnessed execution (aOR: 2.4; 1.1-5.2), family member death (aOR: 2.2; 1.2-4.2), and multiple exposures (aOR: 2.7; 1.4-5.1). PTSD was independently associated with IBS (aOR: 2.6; 1.2-5.7). CONCLUSION: An enduring association was observed in the Nicaragua civilian population between specific civil war-related events and subsequent IBS. Civilian populations in regions with extended armed conflict may warrant provider education and targeted interventions for patients.

RESUMEN

To assess "bottom-up" to "top-down" trophic transfer, we analyze As, Cd, Co, Cr, Cu, Hg, Ni, Se, Zn, Fe, and Mn from two sediment chemical fractions (exchangeable and organic-bound), red mangrove (Rhizophora mangle) leaves, and fiddler crab (M. rapax) soft tissues from Isla del Carmen, Yucatán Peninsula. Both mechanisms were observed indictive that R. mangle and M. rapax indeed bioaccumulated the toxic elements from the different matrices with the latter being a macro-concentrator only for Cu and Zn. Although the modified Geo-accumulation factor (combined exchangeable and organic matter fractions) suggested that the studied sites are practically "uncontaminated", Hg is the only toxic element to be having a "moderately to strongly" impact. Data shows how M. rapax had progressively bioaccumulated Hg, but no biomagnification could be corroborated given that the fiddler crab behaved as a de-concentrator.

RESUMEN

Ganoderma species are well recognised by their significant role in the recycling of nutrients in ecosystems and by their production of secondary metabolites of medical and biotechnological importance. Ganoderma spp. are characterised by laccate and non-laccate, woody basidiocarps, polypore hymenophores and double-walled basidiospores generally with truncate apex. Despite the importance of this genus, its taxonomy is unclear and it includes several species' complexes with few circumscribed species and incorrect geographic distributions. The aim of this work was to provide detailed morphological descriptions together with phylogenetic analyses using ITS sequences to confirm the presence of seven species of Ganoderma in Costa Rica: G.amazonense, G.applanatum s.l., G.australe, G.curtisii, G.ecuadorense, G.oerstedii and G.parvulum. This is the first study that integrates morphological and phylogenetic data of Ganoderma from Central America and a key of the neotropical species. Besides, the distribution range of G.curtisii, previously reported from North America and G.ecuadorense from South America, is expanded to Central America.

RESUMEN

Mountains harbor a significant number of the World's biodiversity, both on tropical and temperate regions. Notably, one crucial gap in conservation is the consideration of historical and contemporary patterns influencing differential distribution in small mammal mountain species and how climate change will affect their distribution and survival. The mice Peromyscus mexicanus species group is distributed across mountains in Guatemala-Chiapas and Central America, which experienced significant effects of glacial and interglacial cycles. We determined phylogeographic and demographic patterns of lowlands and highlands mountain lineages, revealing that the radiation of modern P. mexicanus lineages occurred during the Pleistocene (ca. 2.6 mya) along Nuclear Central America. In concert with climatic cycles and the distribution of habitats, lowland and highland lineages showed recent population size increase and decrease, respectively. We also estimated the current and future distribution ranges for six lineages, finding marked area size increase for two lineages for which vegetation type and distribution would facilitate migrating towards higher elevations. Contrastingly, three lineages showed range size decrease; their ecological requirements make them highly susceptible to future habitat loss. Our findings are clear evidence of the negative impacts of future climate change, while our ability to manage and conserve these vulnerable ecosystems and mountain species is contingent on our understanding of the implications of climate change on the distribution, ecology, and genetics of wildlife populations.

RESUMEN

In Central America, childhood cancer is one of the leading causes of death. It is also a significant disease burden to health systems, with social and economic implications for families. The World Health Organization (WHO), the Executive Secretary of the Council of Ministers of Health of Central America and the Dominican Republic (SE-COMISCA), the Pan American Health Organization (PAHO), and St Jude Children's Research Hospital are working collaboratively to strengthen the health system's response to childhood cancer in Central America and the Dominican Republic. This collaboration's primary objective is to support the development of national pediatric cancer plans for each country in the subregion and improve overall survival rates and quality of care for children with cancer through a more comprehensive universal health coverage package. This collaborative effort has led to: (i) the development of childhood cancer national action plans; (ii) the launch of awareness and promotion campaigns; (iii) the design of childhood cancer educational material for children and their families; and (iv) a platform for professionals working in childhood cancer to share good practices and successful experiences. The countries of the subregion together with PAHO and St Jude Children's Research Hospital are working to develop standardized evidence-based clinical practice guidelines on childhood cancer for the region. This brief communication reports on this collaborative work.


En Centroamérica, el cáncer infantil es una de las principales causas de muerte. La enfermedad también supone una carga considerable para los sistemas de salud y tiene implicaciones sociales y económicas para las familias. La Organización Mundial de la Salud (OMS), la Secretaría Ejecutiva del Consejo de Ministros de Salud de Centroamérica y República Dominicana (SE-COMISCA), la Organización Panamericana de la Salud (OPS) y el St Jude Children's Research Hospital están trabajando conjuntamente para fortalecer la respuesta de los sistemas de salud frente al cáncer infantil en Centroamérica y República Dominicana. El objetivo principal de esta colaboración es respaldar la elaboración de un plan nacional sobre el cáncer pediátrico para cada país de la subregión y mejorar las tasas de supervivencia global y la calidad de la atención que se presta a la población infantil con cáncer mediante un programa más completo de cobertura universal de salud. Este esfuerzo de colaboración ha dado lugar a: a) la elaboración de planes de acción nacionales sobre el cáncer infantil; b) la puesta en marcha de campañas de concientización y promoción; c) el diseño de materiales educativos sobre el cáncer en la infancia para la población infantil y sus familias; y d) una plataforma para que los profesionales que trabajan en cáncer infantil intercambien buenas prácticas y experiencias exitosas. Los países de la subregión, junto con la OPS y el St Jude Children's Research Hospital, están trabajando en la elaboración para Centroamérica de unas directrices de práctica clínica sobre cáncer infantil que estén estandarizadas y basadas en la evidencia.

RESUMEN

Costa Rica's rice production, a large determinant of the country's food security, is being negatively impacted by frequently increasing periods of intense drought. Costa Rican scientists have applied CRISPR/Cas9 to develop drought resistant rice varieties they believe the country's rice producers could benefit from. However, would Costa Ricans consume gene edited rice or products derived from this crop? A three-part, 26-question survey administered in-person to 1096 Costa Ricans uncovers their attitudes, knowledge, and perceptions of gene editing technology and crops. Multiple regressions were built where the independent variables were age, gender, education level, and subjective economic situation. No statistically significant relationships were found in the regression coefficients. Moreover, the k-means procedure (cluster analysis) was used to categorize respondents according to their attitudes on the consumption of gene-edited foods: negative, neutral, and positive. Results show that overall, Costa Rican consumers are open to the application of gene editing in agriculture and would consider consuming products derived from the application of the technology. They are also open to gene editing technology being used to address human and animal health issues. However, Costa Rican consumers are not open to gene editing being used to "design" human traits. This study adds evidence to the emerging literature on the acceptance of gene-edited food. It also highlights the importance of informing societies of just how vulnerable agriculture, and therefore food security, is to the increasingly adverse effects of climate change.
