Incidence of childhood cancer in Costa Rica, 2000-2014: An international perspective.

Estimating childhood cancer incidence globally is hampered by a lack of reliable data from low- and middle-income countries. Costa Rica is one of the few middle-income countries (MIC) with a long-term high quality nationwide population-based cancer registry.


Multidrug-resistant Clostridium difficile ribotypes 078 and 014/5-FLI01 in piglets from Costa Rica.

Though an overlap of Clostridium difficile PCR ribotypes (RT) in humans and animals has been noted -particularly in piglets-information regarding C. difficile isolates from swine is scarce in Latin America. A characterization of 10 C. difficile isolates obtained from this origin in Costa Rica revealed the presence of the RT078 (n = 4) and RT014/5-FLI01 (n = 6) ribotypes. Unlike two previous reports from the region, all isolates were multidrug resistant (MDR). According to a minimum spanning tree (MS...

Taxonomy and phylogeny of Pyrrhoderma: a redefinition, the segregation of Fulvoderma, gen. nov., and identifying four new species.

Previously, Pyrrhoderma accommodated two polypore species, P. adamantinum and P. scaurum; however, phylogenetic studies indicated that these two species were not congeneric within the Hymenochaetaceae and that P. adamantinum formed a clade with Phellinidium noxium. To resolve the relationships among the two species of Pyrrhoderma and other related taxa, specimens from China, Costa Rica, Singapore, and Thailand were studied from both morphological and phylogenetic perspectives. A new genus, Fulvoderma, is er...


Enterococci as a key parameter for water quality index: Purires River, Costa Rica.

This study used the Canadian Water Quality Index (CWI) to characterize water sampled at three points within the Purires River micro basin, Costa Rica. The first sampling point is located in a high zone with domestic agricultural activities, the second point around the mid-point of the flow of the river, and the third point at the lowest zone with extensive agricultural activities mainly centered on the production of fresh vegetables. Eleven physicochemical parameters (As, Cd, Cr, biochemical oxygen demand (...

Intragenomic nuclear RNA variation in a cryptic Amanita taxon.

Amanita cf. lavendula collections in eastern North America, Mexico, and Costa Rica were found to consist of four cryptic taxa, one of which exhibited consistently unreadable nuclear rDNA ITS1-5.8S-ITS2 (fungal barcode) sequences after ITS1 base 130. This taxon is designated here as Amanita cf. lavendula taxon 1. ITS sequences from dikaryotic basidiomata were cloned, but sequences recovered from cloning did not segregate into distinct haplotypes. Rather, there was a mix of haplotypes that varied among themse...

Functional Precision Polymers via Stereo- and Regioselective Polymerization Using Group 6 Metal Alkylidene and Group 6 and 8 Metal Alkylidene N-Heterocyclic Carbene Complexes.

The concepts of functional precision polymers and the latest accomplishments in their synthesis are summarized. Synthetic concepts based on chain growth polymerization are compared to iterative synthetic approaches. Here, the term "functional precision polymers" refers to polymers that are not solely hydrocarbon-based but contain functional groups and are characterized by a highly ordered primary structure. If insertion polymerization is used for their synthesis, olefin metathesis-based polymerization techn...

Venom gland transcriptomics and microRNA profiling of juvenile and adult yellow-bellied sea snake, Hydrophis platurus, from Playa del Coco (Guanacaste, Costa Rica).

With an extensive range in tropical and subtropical waters of Indo-Australian region and the Pacific coast of the American continent, the yellow-bellied sea snake, Hydrophis platurus, is the most broadly distributed snake species on our planet. We report a comparative analysis of the mRNA and microRNA transcriptional profiles of the venom glands of Costa Rican juvenile and adult yellow-bellied sea snakes, and correlate these datasets with the previously reported venom proteome gathered from an adult specime...

A Practice-Oriented Review of Health Concepts.

Whereas theories on health generally argue in favor of one specific concept, we argue that, given the variety of health practices, we need different concepts of health. We thus approach health concepts as a Wittgensteinian family of thick concepts. By discussing five concepts of health offered by (philosophical) theory, we argue that all capture something that seems relevant when we talk and think about health. Classifying these concepts reveals their family resemblances: each of these concepts differs from...

Pansusceptible Escherichia coli isolates obtained from feces of free-ranging Baird's Tapirs (Tapirus bairdii), suggests a low selective pressure of resistant determinants, in the North-western region of the Talamanca Mountain Range, Costa Rica.

The main objective of this study was to analyze the antibiotic susceptibility profile of Escherichia coli isolates obtained from fecal samples of free-ranging Baird's tapirs (Tapirus bairdii) in the North-western region of the Talamanca Mountain Range.

Lack of alkaloids and tetrodotoxin in the neotropical frogs Allobates spp. (Aromobatidae) and Silverstoneia flotator (Dendrobatidae).

Frogs of the family Dendrobatidae are known to contain toxic alkaloids in their skin secretion, but Allobates species of the closely related Aromobatidae family are considered to lack toxic secretions. However, contradictory results have been reported. Analyses of alcohol extracts from three different Allobates species from South-America (Guiana Shield), Central America (Costa Rica), and from the dendrobatid frog Silverstoneia flotator confirm the absence of alkaloids and tetrodotoxin in aromobatids and in ...

Interethnic Variability in CYP2D6, CYP2C9, and CYP2C19 Genes and Predicted Drug Metabolism Phenotypes Among 6060 Ibero- and Native Americans: RIBEF-CEIBA Consortium Report on Population Pharmacogenomics.

Pharmacogenetic variation in Latin Americans is understudied, which sets a barrier for the goal of global precision medicine. The RIBEF-CEIBA Network Consortium was established to characterize interindividual and between population variations in CYP2D6, CYP2C9, and CYP2C19 drug metabolizing enzyme genotypes, which were subsequently utilized to catalog their "predicted drug metabolism phenotypes" across Native American and Ibero American populations. Importantly, we report in this study, a total of 6060 heal...

Molecular phylogenetics of Neotropical detritivorous fishes of the family Curimatidae (Teleostei: Characiformes).

Curimatidae, the fourth largest family of detritivorous Neotropical characiform fishes, encompasses eight extant genera and over 110 species dwelling in diverse freshwater habitats from Costa Rica to Argentina. Extensive phylogenetic analyses of soft anatomy and osteology provided evidence for intergeneric and most interspecific relationships, and formed the basis of curimatid taxonomy for nearly 40 years. However, that morphological phylogeny demonstrated incomplete phylogenetic resolution at various scale...

Complex overlapping concepts: An effective auditing methodology for families of similarly structured BioPortal ontologies.

In previous research, we have demonstrated for a number of ontologies that structurally complex concepts (for different definitions of "complex") in an ontology are more likely to exhibit errors than other concepts. Thus, such complex concepts often become fertile ground for quality assurance (QA) in ontologies. They should be audited first. One example of complex concepts is given by "overlapping concepts" (to be defined below.) Historically, a different auditing methodology had to be developed for every s...

Determinants of Soil Bacterial and Fungal Community Composition Toward Carbon-Use Efficiency Across Primary and Secondary Forests in a Costa Rican Conservation Area.

Tropical secondary forests currently represent over half of the world's remaining tropical forests and are critical candidates for maintaining global biodiversity and enhancing potential carbon-use efficiency (CUE) and, thus, carbon sequestration. However, these ecosystems can exhibit multiple successional pathways, which have hindered our understanding of the soil microbial drivers that facilitate improved CUE. To begin to address this, we examined soil % C; % N; C:N ratio; soil microbial biomass C (C); NO...

Gene ontology concept recognition using named concept: understanding the various presentations of the gene functions in biomedical literature.

A major challenge in precision medicine is the development of patient-specific genetic biomarkers or drug targets. The firsthand information of the genes associated with the pathologic pathways of interest is buried in the ocean of biomedical literature. Gene ontology concept recognition (GOCR) is a biomedical natural language processing task used to extract and normalize the mentions of gene ontology (GO), the controlled vocabulary for gene functions across many species, from biomedical text. The previous ...

Thyroid Cancer "Epidemic" also Occurs in Low- and Middle-income countries.

Thyroid cancer incidence varies greatly between and within high-income countries (HICs), and overdiagnosis likely plays a major role in these differences. Yet, little is known about the situation in low- and middle-income countries (LMICs). We compare up-to-date thyroid cancer incidence and mortality at national and subnational levels. 599,851 thyroid cancer cases in subjects aged 20-74 reported in Cancer Incidence in Five Continents volume XI from 55 countries with at least 0.5 million population, aged 20-...

Precision Surgery for Obesity.

Precision medicine is targeted towards improving the effectiveness of treatment, reducing the side effects of drugs and reducing medical costs. The application of precision surgery for obesity is a new concept that involves 2 stages: the first stage is to attain a precise obesity surgery, and the second stage is to achieve individualized obese gene therapy. In this article, we discuss the value of precision surgery for obesity, its stages and its future application to improve obesity surgery. Due to recent ...

Distinguishing the precision of spatial recollection from its success: Evidence from healthy aging and unilateral mesial temporal lobe resection.

Successful episodic recollection can vary in the precision of the information recalled. The hypothesis that recollection precision requires functional neuroanatomical contributions distinct from those required for recollection success remains controversial. Some findings in individuals with hippocampal lesions have indicated that precision is dependent on the hippocampus. However, other neuroimaging and lesion studies have implicated regions outside of the mesial temporal lobe (MTL) in precision, such as pa...

Learning to become a primary care professional: insights from threshold concept theory.

Threshold Concepts are fundamental ideas within a discipline which are transformative, integrative, irreversible and usually troublesome. This article describes the threshold concept framework and discusses how it can offer new insights into how we focus teaching and facilitate learning around these concepts, such as uncertainty. Relevant research from a range of health disciplines are explored to consider which concepts may be critical to thinking and practising effectively in primary care. In addition, it...

New species of Plectromacronema Ulmer 1906 (Trichoptera: Hydropsychidae) from Brazil, with association of immature stages and aspects of its biology.

Plectromacronema Ulmer 1906 is a Neotropical genus recorded sparsely from South of Mexico to the North of Argentina. The genus is placed within the Macronematinae sub-family, members of which are relatively large among the Trichoptera and bears conspicuous wing ornamentations. There are only two species recorded for Brazil, Plectromacronema comptum Ulmer 1906 and Plectromacronema subfuscum (Banks 1920). Plectromacronema lisae Flint 1983 recorded for Mexico and Costa Rica is the only species in the genus wit...

Response to Costa, Lemos, and Paneque Letter to the Editor.

Public-private partnerships for e-government in developing countries: An early stage assessment framework.

Although public-private partnerships (PPP) and electronic government (e-government) have proven to be fruitful mechanisms for economic development and emerging economies seem to recognize their importance, consistent methods for analyzing the early planning stages of e-government portfolios are lacking. The present work utilized a comprehensive literature review to understand the evaluation criteria for PPP projects throughout the early-stage planning process. A qualitative meta-synthesis was employed to id...

Application of the ConNECT Framework to Precision Health and Health Disparities.

An emphasis on precision health (PH) has stimulated precision medicine studies to focus on the interplay of biological, behavioral, and environmental factors with disease risks, treatments, prognoses, and outcomes affecting health disparities. It is imperative, as well, that improving health equity among underserved populations remains central to the efforts and aims of PH.
