The inclusion of children with disabilities in oral health research: A systematic review

OBJECTIVE: This systematic review aimed to describe the extent to which oral health research since the advent of the United Nations Convention on the Rights of the Child, the United Nations Convention on the Rights of Persons with Disabilities and the current movement on the inclusion of voices of children, has been done on or with children with disabilities. METHODS: A systematic review of the dental literature for children with disabilities from 2001 to 2017 was conducted. Electronic databases were searched for oral health literature on the involvement of children with disabilities. Each identified article was examined by 2 reviewers against the inclusion criteria and categorized according to the extent to which children with disabilities were involved in oral health research, type of study, children's ages, type of impairment and the country of origin. RESULTS: The search included 113 articles after application of the exclusion criteria. Of these papers, 6.2% were classified as research with children, 41.6% used proxies to gain the perspective of children with disabilities and 52.2% were classified as research on children with disabilities. The majority of studies, which attempted some form of inclusion, were from Sweden and India. CONCLUSIONS: Most oral health research is conducted on children with disabilities (viewing them as objects) rather than with them (viewing them as active participants). Unlike previous systematic reviews which report an increase in the inclusion of the voices of children in oral health research, children with disabilities were mostly excluded from research. Future research should attempt to use methods which involve children with disabilities as fully as possible in the research process. This ensures that their perspectives are obtained and their voices are heard

Exploiting Evolution for an Adaptive Drift-Robust Classifier in Chemical Sensing

Gas chemical sensors are strongly affected by drift, i.e., changes in sensors' response with time, that may turn statistical models commonly used for classification completely useless after a period of time. This paper presents a new classifier that embeds an adaptive stage able to reduce drift effects. The proposed system exploits a state-of-the-art evolutionary strategy to iteratively tweak the coefficients of a linear transformation able to transparently transform raw measures in order to mitigate the negative effects of the drift. The system operates continuously. The optimal correction strategy is learnt without a-priori models or other hypothesis on the behavior of physical-chemical sensors. Experimental results demonstrate the efficacy of the approach on a real problem

Access to oral health care services for children with disabilities: a mixed methods systematic review

BACKGROUND: Children with disabilities experience poorer oral health and frequently have complex needs. The accessibility of oral health care services for children with disabilities is crucial for promoting oral health and overall well-being. This study aimed to systematically review the literature to identify the barriers and facilitators to oral health care services for children with disabilities, and to propose priority research areas for the planning and provision of dental services to meet their needs. METHODS: This was a mixed methods systematic review. Multiple databases searched included MEDLINE, Scopus, PsycINFO, EMBASE, and CINAHL. The search strategy included Medical Subject Heading (MeSH) terms related to children, disabilities, and access to oral health. Eligibility criteria focused on studies about children with disabilities, discussing the accessibility of oral health care. RESULTS: Using Levesque's framework for access identified barriers such as professional unwillingness, fear of the dentist, cost of treatment, and inadequate dental facilities. Facilitators of access offered insight into strategies for improving access to oral health care for children with disabilities. CONCLUSION: There is a positive benefit to using Levesque's framework of access or other established frameworks to carry out research on oral healthcare access, or implementations of dental public health interventions in order to identify gaps, enhance awareness and promote better oral health practices. The evidence suggests that including people with disabilities in co-developing service provision improves accessibility, alongside using tailored approaches and interventions which promote understanding of the importance of dental care and increases awareness for professionals, caregivers and children with disabilities.

Origins of the Ambient Solar Wind: Implications for Space Weather

The Sun's outer atmosphere is heated to temperatures of millions of degrees, and solar plasma flows out into interplanetary space at supersonic speeds. This paper reviews our current understanding of these interrelated problems: coronal heating and the acceleration of the ambient solar wind. We also discuss where the community stands in its ability to forecast how variations in the solar wind (i.e., fast and slow wind streams) impact the Earth. Although the last few decades have seen significant progress in observations and modeling, we still do not have a complete understanding of the relevant physical processes, nor do we have a quantitatively precise census of which coronal structures contribute to specific types of solar wind. Fast streams are known to be connected to the central regions of large coronal holes. Slow streams, however, appear to come from a wide range of sources, including streamers, pseudostreamers, coronal loops, active regions, and coronal hole boundaries. Complicating our understanding even more is the fact that processes such as turbulence, stream-stream interactions, and Coulomb collisions can make it difficult to unambiguously map a parcel measured at 1 AU back down to its coronal source. We also review recent progress -- in theoretical modeling, observational data analysis, and forecasting techniques that sit at the interface between data and theory -- that gives us hope that the above problems are indeed solvable.Comment: Accepted for publication in Space Science Reviews.

Human antigen R as a therapeutic target in pathological cardiac hypertrophy

RNA binding proteins represent an emerging class of proteins with a role in cardiac dysfunction. We show that activation of the RNA binding protein human antigen R (HuR) is increased in the failing human heart. To determine the functional role of HuR in pathological cardiac hypertrophy, we created an inducible cardiomyocyte-specific HuR-deletion mouse and showed that HuR deletion reduces left ventricular hypertrophy, dilation, and fibrosis while preserving cardiac function in a transverse aortic constriction (TAC) model of pressure overload-induced hypertrophy. Assessment of HuR-dependent changes in global gene expression suggests that the mechanistic basis for this protection occurs through a reduction in fibrotic signaling, specifically through a reduction in TGF-β (Tgfb) expression. Finally, pharmacological inhibition of HuR at a clinically relevant time point following the initial development of pathological hypertrophy after TAC also yielded a significant reduction in pathological progression, as marked by a reduction in hypertrophy, dilation, and fibrosis and preserved function. In summary, this study demonstrates a functional role for HuR in the progression of pressure overload-induced cardiac hypertrophy and establishes HuR inhibition as a viable therapeutic approach for pathological cardiac hypertrophy and heart failure

Measurement of the Isolated Photon Cross Section in p-pbar Collisions at sqrt{s}=1.96 TeV

The cross section for the inclusive production of isolated photons has been measured in p anti-p collisions at sqrt{s}=1.96 TeV with the D0 detector at the Fermilab Tevatron Collider. The photons span transverse momenta 23 to 300 GeV and have pseudorapidity |eta|<0.9. The cross section is compared with the results from two next-to-leading order perturbative QCD calculations. The theoretical predictions agree with the measurement within uncertainties.Comment: 7 pages, 5 figures, submitted to Phys.Lett.

Effects of watershed land use on nitrogen concentrations and δ15 Nitrogen in groundwater

The definitive version was published in Biogeochemistry 77 (2006): 199-215, doi:10.1007/s10533-005-1036-2.Eutrophication is a major agent of change affecting freshwater, estuarine, and marine systems. It is largely driven by transportation of nitrogen from natural and anthropogenic sources. Research is needed to quantify this nitrogen delivery and to link the delivery to specific land-derived sources. In this study we measured nitrogen concentrations and δ15N values in seepage water entering three freshwater ponds and six estuaries on Cape Cod, Massachusetts and assessed how they varied with different types of land use. Nitrate concentrations and δ15N values in groundwater reflected land use in developed and pristine watersheds. In particular, watersheds with larger populations delivered larger nitrate loads with higher δ15N values to receiving waters. The enriched δ15N values confirmed nitrogen loading model results identifying wastewater contributions from septic tanks as the major N source. Furthermore, it was apparent that N coastal sources had a relatively larger impact on the N loads and isotopic signatures than did inland N sources further upstream in the watersheds. This finding suggests that management priorities could focus on coastal sources as a first course of action. This would require management constraints on a much smaller population.This work was supported by funds from the Woods Hole Oceanographic Institution Sea Grant Program, from the Cooperative Institute for Coastal and Estuarine Environmental Technology, from Massachusetts Department of Environmental Protection to Applied Science Associates, Narragansett, RI, as well as from Palmer/McLeod and NOAA National Estuarine Research Reserve Fellowships to Kevin Kroeger.
