description: As high-throughput technologies in genomics, transcriptomics, and proteomics evolve, questions arise about their use in the assessment of occupational cancers. To address these questions, the National Institute for Occupational Safety and Health, the National Cancer Institute, the National Institute of Environmental Health Sciences, and the American Chemistry Council sponsored a workshop 8-9 May 2002 in Washington, DC. The workshop brought together 80 international specialists whose objective was to identify the means for best exploiting new technologies to enhance methods for laboratory investigation, epidemiologic evaluation, risk assessment, and prevention of occupational cancer. The workshop focused on identifying and interpreting markers for early biologic effect and inherited modifiers of risk.

description: In this paper, we prove that all spherically symmetric Landsberg surfaces are Berwaldian. We modify the classification of spherically symmetric Finsler metrics, done by the author in [S. G. Elgendi, On the classification of Landsberg spherically symmetric Finsler metrics, Int. J. Geom. Methods Mod. Phys. 18 (2021)], of Berwald type of dimension $n\geq 3$. Precisely, we show that all Berwald spherically symmetric metrics of dimension $n\geq 3$ are Riemannian or given by a certain formula. As a simple class of Berwaldian metrics, we prove that all spherically symmetric metrics in which the function $ϕ$ is homogeneous of degree $-1$ in $r$ and $s$ are Berwaldian.

description: Since its conception, the computer has found applications to accompany human creativity. Today, the debate about computers and creativity involves several challenges, such as understanding human creativity, modeling the creative process, and programming the computer to exhibit behavior that appears to be creative to some extent. In this paper, we are interested in how the computer can be used as a tool to promote creativity in a musical composition. We automatically extracted the brightness curve from a silent movie and then used it to compose a piece of music to accompany the movie. We extracted several parameters from the brightness curve, and applied compositional rules from these parameters to write the instrumental music for the film. The final composition has a synchronicity and aesthetic fit with the film that are surprising. This compositional process also allowed for a degree of aesthetic freedom that would otherwise have been impossible.

Applications and advantages of using sexed semen in dairy cattle
Creators: name: Dr. J.Sai Kiran1.,  Dr. N.Rajanna2., Dr. J.Shashank3
Publisher: name: veterinary today
Year: 2024

description: Sexed semen refers to semen that has been processed to contain a higher proportion of either X or Y chromosome-bearing sperm, allowing the production of offspring of a desired sex, either male or female. Current technologies can achieve 80-90% accuracy in producing sexed semen. In bovines, the X chromosome is larger than the Y chromosome, so X chromosome-bearing sperm cells have about 3.8% more DNA content. By using a dye that binds proportionally to DNA, sperm cells can be differentiated based on whether they carry the X or Y chromosome. This difference in DNA content is the basis for the commercial methods used to create sexed semen. Dairy farmers can use this technology to produce offspring of a desired sex and reduce the issue of unwanted male animals. The full potential of this technology is realized when combined with in vitro fertilization (IVF), as oocytes from multiple donors can be fertilized with a single dose of sexed semen, facilitating the production of sexed embryos.

Brominated Flame Retardants: Cause for Concern?

Year: 2004

description: Brominated flame retardants (BFRs) have routinely been added to consumer products for several decades in a successful effort to reduce fire-related injury and property damage. Recently, concern for this emerging class of chemicals has risen because of the occurrence of several classes of BFRs in the environment and in human biota. The widespread production and use of BFRs; strong evidence of increasing contamination of the environment, wildlife, and people; and limited knowledge of potential effects heighten the importance of identifying emerging issues associated with the use of BFRs. In this article, we briefly review scientific issues associated with the use of tetrabromobisphenol A, hexabromocyclododecane, and three commercial mixtures of polybrominated diphenyl ethers and discuss data gaps. Overall, the toxicology database is very limited; the current literature is incomplete and often conflicting. Available data, however, raise concern over the use of certain classes of brominated flame retardants.

data harmonization
community-based initiative

description: This presentation is about a data harmonization initiative for researchers working with the CBS microdata. The motivation behind this community-based initiative is to facilitate easier, less time-consuming data harmonization, particularly to optimize the combining of different CBS microdata files. How? By making data harmonization-scripts openly accessible through GitHub. For more information about the initiative, please have a look at this presentation, the abstract below, and the GitHub repository https://github.com/MMJHendriks/HarmonizationScripts_CBSmicrodata. Moreover, we would like to encourage other researchers working with CBS microdata to publish their harmonization-scripts on this GitHub repository! Abstract For researchers working with CBS microdata, data harmonization is an unavoidable but time-consuming part the data analysis process. Data harmonization refers to the effort of combining data from different sources with varying file locations, file formats, and naming conventions, and transforming it into a single cohesive data set. Our aim is to provide communal services for CBS microdata-users by making data harmonization-scrips openly and easily accessible. While the CBS microdata infrastructure facilitates ground-breaking research, it remains a challenge for researchers to manage the vast amount of datafiles, the documentation and to link the data. Why is data harmonization challenging? The CBS microdata has different file formats (i.e. -bus and -tab files with observations by year, month or periods), file paths (which change when files are moved or new versions are published), subject areas with data in multiple (sub)folders, and naming conventions. Currently, most CBS microdata-users spend a considerable amount of time harmonizing the same data, reinventing the wheel. In the project Children and (future) Parents, supported by Prediction and Professionals in Prevention, to improve Opportunity researchers work with CBS microdata on child health and development, demographic variables and parental characteristics. We have harmonized microdata of eleven data topics, and have made the R scripts openly accessible via GitHub. The intention is that other CBS microdata-users can use these ‘harmonization-scripts’; run the scripts in the Remote Access environment and easily extract the harmonized data of interest. Moreover, we will encourage other users of CBS microdata to publish harmonization-scripts on this GitHub repository. This communal data harmonization services initiative for users of CBS microdata provides a range of benefits: increasing visibility of harmonization efforts, optimizing reproducibility to reduce time-consuming work, and improving efficiency. Not only does this initiative promote the implementation of Open Science and FAIR principles, it might also stimulate users of CBS microdata to cooperate.
Two-body state with p-wave interaction in one-dimensional waveguides under transversely anisotropic confinement

description: We theoretically study two atoms with $p$-wave interaction in a one-dimensional waveguide, and investigate how the transverse anisotropy of the confinement affects the two-body state, especially, the properties of the resonance. For bound-state solution, we find there are totally three two-body bound states due to the richness of the orbital magnetic quantum number of $p$-wave interaction, while only one bound state is supported by $s$-wave interaction. Two of them become nondegenerate due to the breaking of the rotation symmetry under transversely anisotropic confinement. For scattering solution, the effective one-dimensional scattering amplitude and scattering length are derived. We find the position of the $p$-wave confinement-induced resonance shifts apparently as the transverse anisotropy increases. In addition, a two-channel mechanism for confinement-induced resonance in a one-dimensional waveguide is generalized to $p$-wave interaction, which was proposed only for $s$-wave interaction before. All our calculations are based on the parameterization of the $^{40}$K atom experiments, and can be confirmed in future experiments.

description: The possibility of an emergent universe solution to Einstein's field equations allowing for an irreversible creation of matter at the expense of the gravitational field is shown. With the universe being chosen as spatially flat FRW spacetime together with equation of state proposed in [17], the solution exists when the ratio of the phenomenological matter creation rate to the number density times the Hubble parameter is a number $β$ of the order of unity and independent of time. The thermodynamic behaviour is also determined for this solution. Interestingly, we also find that an emergent universe scenario is present with usual equation of state in cosmology when the matter creation rate is chosen to be a constant. More general class of emergent universe solutions are also discussed.

Simulation and analysis code for the paper "Smc5/6 association with microtubules controls dynamic pericentromeric chromatin folding"
Creators: name: Pinholt, Henrik Dahl
Publisher: name: Zenodo
Year: 2024

description:  

This folder contains the code to reproduce simulations and plots in the paper "Smc5/6 association with microtubules controls dynamic pericentromeric chromatin folding".

Code to install dependencies

The code relies heavily on the the GPU-capable simulation framework openmm and the polymer-simulation specific wrapper polychrom. To run the code in this folder these, and other dependencies, must be installed. A minimal conda environment can be created using the following commands:conda create -n testenvconda install -c omnia openmmpip install -U git+https://github.com/mirnylab/polychrompip install h5py ipython ipykernel matplotlib numpy tqdm multiprocess joblib noctiluca

Code to run simulations

The repository contains the following scripts to generate simulation data:

1_Time_calibration_and_WT.py

2_softer_microtubule_sim.py

3_larger_persistence_length.py

4_larger_persistence_length_with_softer_microtubule.py

To run these scripts, the folder starting_conformation_diploid_fullyequill and the file Currently_used_Yeast_params.py must be in the same directory as the script (and unzipped if folder).

Having performed the above-listed installations of dependencies, the scripts may be run from a GPU-capable computer with a command like:python 2_softer_microtubule_sim.py 0 3 where the first index specifies the GPU to use (should always be 0 if there is only one on the computer) and the second index specifies which replicate this is. The only effect of the second index is in naming the output files (see examples in the data folder). The output from this example call would be the folder 2_softer_microtubule_sim_3 within which the polymer configurations during the simulation are stored along with some metadata.Each of the scripts above were run in 7 replicates to generate the results in the data folder.

Code to generate analysis plots

The simulation results were analyzed in the three jupyter notebooks

Analyze_1_Time_calibration_and_WT.ipynb

This notebook analyzes the results of the "wild type" simulation (1_Time_calibration_and_WT.py) and generates the plot used for Figure 4a as well as the time calibration.

Analyze_2_larger_persistence_length.ipynb

This notebook analyzes the results of the simulation 2_larger_persistence_length.py and generates the plots for Figure 4c and Figure S7.

Analyze_3_larger_persistence_length_with_softer_microtubule.ipynb

This notebook analyzes the results of simulations 2_softer_microtubule_sim.py 3_larger_persistence_length_with_softer_microtubule.py and generates the plots for Figure 4b and 4d and Figure S6 and Figure S8.

All notebooks require that the data folder be unzipped prior to running.

description: Parental exposure to pesticides may contribute to childhood cancer risk. Through the Agricultural Health Study, a prospective study of pesticide applicators in Iowa and North Carolina, we examined childhood cancer risk and associations with parental pesticide application. Identifying information for 17,357 children of Iowa pesticide applicators was provided by parents via questionnaires (1993-1997) and matched against the Iowa Cancer Registry. Fifty incident childhood cancers were identified (1975-1998). Risk of all childhood cancers combined was increased [standardized incidence ratio (SIR) = 1.36; 95% confidence interval (CI), 1.03-1.79]. Risk of all lymphomas combined was also increased (SIR = 2.18; 95% CI, 1.13-4.19), as was risk of Hodgkin's lymphoma (SIR = 2.56; 95% CI, 1.06-6.14). We used logistic regression to explore associations between self-reported parental pesticide application practices and childhood cancer risk. No association was detected between frequency of parental pesticide application and childhood cancer risk. An increased risk of cancer was detected among children whose fathers did not use chemically resistant gloves [odds ratio (OR) = 1.98; 95% CI, 1.05-3.76] compared with children whose fathers used gloves. Of 16 specific pesticides used by fathers prenatally, ORs were increased for aldrin (OR = 2.66), dichlorvos (OR = 2.06), and ethyl dipropylthiocarbamate (OR = 1.91). However, these results were based on small numbers and not supported by prior biologic evidence. Identification of excess lymphoma risk suggests that farm exposures including pesticides may play a role in the etiology of childhood lymphoma.

description: Displays can be thought of as relative versions of Fontaine's notion of strongly divisible lattice from integral $p$-adic Hodge theory. In favourable circumstances, the crystalline cohomology of a smooth projective $R$-scheme $X$ is endowed with a display-structure coming from complexes associated with the relative de Rham-Witt complex $WΩ_{X/R}^{\bullet}$ of [LZ04]. In this article, we use the crystal of relative displays of [GL21] to prove a Grothendieck-Messing type result for the deformation theory of Calabi-Yau threefolds.

We have revealed a characteristic pressure-induced Yb valence crossover within the temperature-pressure phase diagram, and a first-order metamagnetic transition is found below $P_{\rm c}$ $\sim$ 9 GPa where the system undergoes a pressure-induced antiferromagnetic transition. As a possible origin of the metamagnetic behavior, a critical valence fluctuation emerging near the critical point of the first-order valence transition is discussed on the basis of the temperature-field-pressure phase diagram.

description: Multicomponent metallo-supramolecular assembly allows to rationally combine different building blocks. Discrete multifunctional hosts with an accessible cavity can be prepared in a non-statistical fashion. We employ our shape-complementary assembly (SCA) method to achieve for the first time integrative self-sorting of heteroleptic PdII cages showing guest-tunable circularly polarized luminescence (CPL). An enantiopure helicene-based ligand (M or P configuration) is coupled with a non-chiral emissive fluorenone-based ligand (A or B) to form a series of Pd2L2L’2 assemblies. The modular strategy allows to impart the chiral information of the helicenes to the overall supramolecular system, resulting in CPL from the non-chiral component. Guest binding results in a 4-fold increase of CPL intensity. The principle offers potential to generate libraries of multifunctional materials with applications in molecular recognition, enantioselective photo-redox catalysis and information processing.

Developmental Neurotoxicity of Pyrethroid Insecticides: Critical Review and Future Research Needs

description: Pyrethroid insecticides have been used for more than 40 years and account for 25% of the worldwide insecticide market. Although their acute neurotoxicity to adults has been well characterized, information regarding the potential developmental neurotoxicity of this class of compounds is limited. There is a large age dependence to the acute toxicity of pyrethroids in which neonatal rats are at least an order of magnitude more sensitive than adults to two pyrethroids. There is no information on age-dependent toxicity for most pyrethroids. In the present review we examine the scientific data related to potential for age-dependent and developmental neurotoxicity of pyrethroids. As a basis for understanding this neurotoxicity, we discuss the heterogeneity and ontogeny of voltage-sensitive sodium channels, a primary neuronal target of pyrethroids. We also summarize 22 studies of the developmental neurotoxicity of pyrethroids and review the strengths and limitations of these studies. These studies examined numerous end points, with changes in motor activity and muscarinic acetylcholine receptor density the most common. Many of the developmental neurotoxicity studies suffer from inadequate study design, problematic statistical analyses, use of formulated products, and/or inadequate controls. These factors confound interpretation of results. To better understand the potential for developmental exposure to pyrethroids to cause neurotoxicity, additional, well-designed and well-executed developmental neurotoxicity studies are needed. These studies should employ state-of-the-science methods to promote a greater understanding of the mode of action of pyrethroids in the developing nervous system.

description: We compute explicit rational models for some Hilbert modular surfaces corresponding to square discriminants, by connecting them to moduli spaces of elliptic K3 surfaces. Since they parametrize decomposable principally polarized abelian surfaces, they are also moduli spaces for genus-2 curves covering elliptic curves via a map of fixed degree. We thereby extend classical work of Jacobi, Hermite, Bolza etc., and more recent work of Kuhn, Frey, Kani, Shaska, Völklein, Magaard and others, producing explicit families of reducible Jacobians. In particular, we produce a birational model for the moduli space of pairs (C,E) of a genus 2 curve C and elliptic curve E with a map of degree n from C to E, as well as a tautological family over the base, for 2 <= n <= 11. We also analyze the resulting models from the point of view of arithmetic geometry, and produce several interesting curves on them.

The quantities are: (i) the electrical resistivity, (ii) the Hall angle, (iii) the Hall Lorenz ratio, (iv) the magnetoresistance and (v) the thermopower. The exponents are the dynamical critical exponent z = 4/3 and an anomalous scaling dimension Phi = -2/3 for the charge density operator.

Robust Learning on Graphs

description: Despite the recent success of graph neural networks (GNNs) in modeling graph-structured data, its vulnerability to adversarial attacks has been revealed, and attacks on both node features and graph structure have been designed. Direct extension of defense algorithms based on adversarial samples meets with the immediate challenge because computing the adversarial network costs substantially. Taking Graph Convolutional Networks (GCN) as a base model, we first present the work of adversarial training via latent perturbation which not only dispenses with generating adversarial networks, but also attains improved robustness and accuracy by respecting the latent manifold of the data. Next, given a threat model based on GCN, we investigate the certificate of robustness for the task of graph classification. Specifically, we develop a method based on Lagrangian dualization to provide a lower bound of classification margin. As a byproduct, we also come up with an efficient attack algorithm to serve an upper bound, measuring the tightness of certificates. Furthermore, to tackle the nonconvexity of activation functions, we propose another method based on the convex envelope, resulting in tight approximation bounds. Lastly, due to the intrinsic properties of graphs, we consider providing the certificate of robustness under permutation invariance. To address it, we first develop a new metric for graphs, named Orthogonal Gromov-Wasserstein (OGW) distance, which formulates a coupling between the structured data based on optimal transportation and optimizes over the orthogonal domain with tractable lower and upper bound. In addition, we build its Fenchel biconjugate to facilitate convex optimization in the certificate problem. By wrapping up with the classification margin criteria and deriving a tight convex envelope formulation, our methods construct the first robustness certificate for graph classification subject to structural permutation invariant constraint.

description: Because of potential exposure both in the workplace and from ambient air, the known carcinogen 1,3-butadiene (BD) is considered a priority hazardous air pollutant. BD and its 2-methyl analog, isoprene (ISO), are chemically similar but have very different toxicities, with ISO showing no significant carcinogenesis. Once released into the atmosphere, reactions with species induced by sunlight and nitrogen oxides convert BD and ISO into several photochemical reaction products. In this study, we determined the relative toxicity and inflammatory gene expression induced by exposure of A549 cells to BD, ISO, and their photochemical degradation products in the presence of nitric oxide. Gas chromatography and mass spectrometry analyses indicate the initial and major photochemical products produced during these experiments for BD are acrolein, acetaldehyde, and formaldehyde, and products for ISO are methacrolein, methyl vinyl ketone, and formaldehyde; both formed < 200 ppb of ozone. After exposure the cells were examined for cytotoxicity and interleukin-8 (IL-8) gene expression, as a marker for inflammation. These results indicate that although BD and ISO alone caused similar cytotoxicity and IL-8 responses compared with the air control, their photochemical products significantly enhanced cytotoxicity and IL-8 gene expression. This suggests that once ISO and BD are released into the environment, reactions occurring in the atmosphere transform these hydrocarbons into products that induce potentially greater adverse health effects than the emitted hydrocarbons by themselves. In addition, the data suggest that based on the carbon concentration or per carbon basis, biogenic ISO transforms into products with proinflammatory potential similar to that of BD products.

description: Recent advances in molecular biology allow the quantification of the transcriptome and scoring transcripts as differentially or equally expressed between two biological conditions. Although these two tasks are closely linked, the available inference methods treat them separately: a primary model is used to estimate expression and its output is post-processed using a differential expression model. In this paper, both issues are simultaneously addressed by proposing the joint estimation of expression levels and differential expression: the unknown relative abundance of each transcript can either be equal or not between two conditions. A hierarchical Bayesian model builds upon the BitSeq framework and the posterior distribution of transcript expression and differential expression is inferred using Markov Chain Monte Carlo (MCMC). It is shown that the proposed model enjoys conjugacy for fixed dimension variables, thus the full conditional distributions are analytically derived. Two samplers are constructed, a reversible jump MCMC sampler and a collapsed Gibbs sampler, and the latter is found to perform best. A cluster representation of the aligned reads to the transcriptome is introduced, allowing parallel estimation of the marginal posterior distribution of subsets of transcripts under reasonable computing time. The proposed algorithm is benchmarked against alternative methods using synthetic datasets and applied to real RNA-sequencing data.

description: We have undertaken a comprehensive review of epidemiologic studies about the effects of radiofrequency fields (RFs) on human health in order to summarize the current state of knowledge, explain the methodologic issues that are involved, and aid in the planning of future studies. There have been a large number of occupational studies over several decades, particularly on cancer, cardiovascular disease, adverse reproductive outcome, and cataract, in relation to RF exposure. More recently, there have been studies of residential exposure, mainly from radio and television transmitters, and especially focusing on leukemia. There have also been studies of mobile telephone users, particularly on brain tumors and less often on other cancers and on symptoms. Results of these studies to date give no consistent or convincing evidence of a causal relation between RF exposure and any adverse health effect. On the other hand, the studies have too many deficiencies to rule out an association. A key concern across all studies is the quality of assessment of RF exposure. Despite the ubiquity of new technologies using RFs, little is known about population exposure from RF sources and even less about the relative importance of different sources. Other cautions are that mobile phone studies to date have been able to address only relatively short lag periods, that almost no data are available on the consequences of childhood exposure, and that published data largely concentrate on a small number of outcomes, especially brain tumor and leukemia.

description: We introduce a versatile numerical method for modeling light diffraction in periodically patterned photonic structures containing quadratically nonlinear non-centrosymmetric optical materials. Our approach extends the generalized source method to nonlinear optical interactions by incorporating the contribution of nonlinear polarization sources to the diffracted field in the algorithm. We derive the mathematical formalism underlying the numerical method and introduce the Fourier-factorization suitable for nonlinear calculations. The numerical efficiency and runtime characteristics of the method are investigated in a set of benchmark calculations: the results corresponding to the fundamental frequency are compared to those obtained from a reference method and the beneficial effects of the modified Fourier-factorization rule on the accuracy of the nonlinear computations is demonstrated. In order to illustrate the capabilities of our method, we employ it to demonstrate strong enhancement of second-harmonic generated in one- and two-dimensional optical gratings resonantly coupled to a slab waveguide. Our method can be easily extended to other types of nonlinear optical interactions by simply incorporating the corresponding nonlinear polarization sources in the algorithm.

description: The attack on the World Trade Center (WTC) created an acute environmental disaster of enormous magnitude. This study characterizes the environmental exposures resulting from destruction of the WTC and assesses their effects on health. Methods include ambient air sampling; analyses of outdoor and indoor settled dust; high-altitude imaging and modeling of the atmospheric plume; inhalation studies of WTC dust in mice; and clinical examinations, community surveys, and prospective epidemiologic studies of exposed populations. WTC dust was found to consist predominantly (95%) of coarse particles and contained pulverized cement, glass fibers, asbestos, lead, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and polychlorinated furans and dioxins. Airborne particulate levels were highest immediately after the attack and declined thereafter. Particulate levels decreased sharply with distance from the WTC. Dust pH was highly alkaline (pH 9.0-11.0). Mice exposed to WTC dust showed only moderate pulmonary inflammation but marked bronchial hyperreactivity. Evaluation of 10,116 firefighters showed exposure-related increases in cough and bronchial hyperreactivity. Evaluation of 183 cleanup workers showed new-onset cough (33%), wheeze (18%), and phlegm production (24%). Increased frequency of new-onset cough, wheeze, and shortness of breath were also observed in community residents. Follow-up of 182 pregnant women who were either inside or near the WTC on 11 September showed a 2-fold increase in small-for-gestational-age (SGA) infants. In summary, environmental exposures after the WTC disaster were associated with significant adverse effects on health. The high alkalinity of WTC dust produced bronchial hyperreactivity, persistent cough, and increased risk of asthma. Plausible causes of the observed increase in SGA infants include maternal exposures to PAH and particulates. Future risk of mesothelioma may be increased, particularly among workers and volunteers exposed occupationally to asbestos. Continuing follow-up of all exposed populations is required to document the long-term consequences of the disaster.

description: Sand patches are one of the precursors to early-stage protodunes and occur widely in both desert and coastal aeolian environments. Here we show field evidence of a mechanism to explain the initiation of sand patches on non-erodible surfaces, such as desert gravels and moist beaches. Changes in sand transport dynamics, directly associated with the height of the saltation layer and variable transport law, observed at the boundary between non-erodible and erodible surfaces lead to sand deposition on the erodible surface. This explains how sand patches can form on surfaces with limited sand availability where linear stability of dune theory does not apply. This new mechanism is supported by field observations that evidence both the change in transport rate over different surfaces and in-situ patch formation that leads to modification of transport dynamics at the surface boundary.

description: This dissertation re-evaluates the significance of civic communities (ciuitates) – largely autonomous polities with state-like attributes – in the Western Roman Empire, from Augustus to Diocletian. Ciuitates have traditionally been studied as administrative structures, fulfilling functions imposed by the Roman government. In contrast, I argue that civic communities behaved as ‘actors’ – entities which pursued communal interests through collective actions. To advance this argument, I take a case-study approach and explore the role of ciuitates as active participants in territorial disputes, the fiscal sphere, and the subordination of other peoples. My approach to agency draws on the historical sociology of Andrew Abbott which emphasises that actors continually change through their interactions. The dissertation shows that civic communities were essential frameworks of collective action through which local populations fostered their communal interests and interacted with other actors, individual and collective. Recognising ciuitates as actors is indispensable if we are to appreciate their impact on the Roman empire and understand how they shaped the empire’s socio-political landscapes over time.

description: Pediatric medical and nursing education currently lacks the environmental health content necessary to appropriately prepare pediatric health care professionals to prevent, recognize, manage, and treat environmental-exposure–related disease. Leading health institutions have recognized the need for improvements in health professionals’ environmental health education. Parents are seeking answers about the impact of environmental toxicants on their children. Given the biologic, psychological, and social differences between children and adults, there is a need for environmental health education specific to children. The National Environmental Education and Training Foundation, in partnership with the Children’s Environmental Health Network, created two working groups, one with expertise in medical education and one with expertise in nursing education. The working groups reviewed the transition from undergraduate student to professional to assess where in those processes pediatric environmental health could be emphasized. The medical education working group recommended increasing education about children’s environmental health in the medical school curricula, in residency training, and in continuing medical education. The group also recommended the expansion of fellowship training in children’s environmental health. Similarly, the nursing working group recommended increasing children’s environmental health content at the undergraduate, graduate, and continuing nursing education levels. Working groups also identified the key medical and nursing organizations that would be important in leveraging these changes. A concerted effort to prioritize pediatric environmental health by governmental organizations and foundations is essential in providing the resources and expertise to set policy and provide the tools for teaching pediatric environmental health to health care providers.
