Laboratory Trend in Vitamin D Status in Ireland: Dual Concerns about Low and High 25OHD.

Serum 25-hydroxyvitamin D (25OHD) is the pre-eminent estimate of vitamin D status that we have been measuring in a hospital laboratory setting since the 1970s. We previously evaluated the trend in 25OHD results in our laboratory from 1993 to 2013. Using a time series analysis of monthly average 25OHD results the trend was modelled, and this was used to forecast monthly average 25OHD from 2014 to 2016. In this study, all 25OHD results from 2014 to 2016 were retrieved (n = 67,922) and trimmed to 40,307 re...

The struggle for existence in the world market ecosystem.

The global trade system can be viewed as a dynamic ecosystem in which exporters struggle for resources: the markets in which they export. We can think that the aim of an exporter is to gain the entirety of a market share (say, car imports from the United States). This is similar to the objective of an organism in its attempt to monopolize a given subset of resources in an ecosystem. In this paper, we adopt a multilayer network approach to describe this struggle. We use longitudinal, multiplex data on trade ...

Mechanistic machine learning: how data assimilation leverages physiologic knowledge using Bayesian inference to forecast the future, infer the present, and phenotype.

We introduce data assimilation as a computational method that uses machine learning to combine data with human knowledge in the form of mechanistic models in order to forecast future states, to impute missing data from the past by smoothing, and to infer measurable and unmeasurable quantities that represent clinically and scientifically important phenotypes. We demonstrate the advantages it affords in the context of type 2 diabetes by showing how data assimilation can be used to forecast future glucose valu...

Long-term prevention of capsular opacification after lens-refilling surgery in a rabbit model.

To reduce capsular opacification by a peri-surgical treatment of the lens capsule with drugs in an in vivo rabbit model. Lens-refilling surgery is a potential therapeutic intervention to treat patients with a cataract lens. The lens material is replaced with an injectable (bio)polymer that retains the natural mechanical and optical lens properties, therewith allowing accommodation. The occurrence of capsular opacification mediated by lens epithelial cells negatively affects accommodation and vision and sho...

Driving forces and mitigation potential of global CO emissions from 1980 through 2030: Evidence from countries with different income levels.

To mitigate global carbon dioxide (CO) emissions in an effective manner, it is essential to identify the driving forces and estimate the reduction potential of changes to CO emissions. Using an extended logarithmic mean Divisia index (LMDI) method, this study decomposes the changes in global emissions between 1980 and 2015 with consideration of different income levels; it also reports on scenario analysis of the global emissions reduction potential up to the year 2030 to explore feasible mitigation pathways...

Myopia and orthokeratology for myopia control.

The prevalence of myopia in children is increasing worldwide and is viewed as a major public health concern. This increase has driven interest in research into myopia prevention and control in children. Although there is still uncertainty in the risk factors underlying differences in myopia prevalence between ethnic groups, rates in children of East Asian descent are typically higher regardless of where they live. Mounting evidence also suggests that myopia prevalence in children increases with age. Earlier...

Contact Lens-Associated Dry Eye Disease: Recent Advances Worldwide and in Japan.

Contact lens wearers complain of various types of contact lens discomfort (CLD), which may result in the discontinuation of contact lenses. CLD is often associated with dry eye disease. A contact lens divides the tear film into two layers: the pre- and post-lens tear film. This change leads to instability of the pre-lens tear film, thinning of pre- and post-lens tear film thickness, and increased friction between the contact lens and the ocular surface. The Japanese Dry Eye Society recommends the diagnosis ...

To investigate topographic changes in corneal epithelial thickness (CET) and stromal thickness following orthokeratology (OK) and to determine associated factors affecting refractive changes.

Dotting the eyes: mouse strain dependency of the lens epithelium to low dose radiation-induced DNA damage.

Epidemiological evidence regarding the radiosensitivity of the lens of the eye and radiation cataract development has led to changes in the EU Basic Safety Standards for protection of the lens against ionizing radiation. However, mechanistic details of lens radiation response pathways and their significance for cataractogenesis remain unclear. Radiation-induced DNA damage and the potential impairment of repair pathways within the lens epithelium, a cell monolayer that covers the anterior hemisphere of the l...

The value of work: Addressing the future of work through the lens of solidarity.

Designing the future of work is crucial to the health and well-being of people and societies. Experts predict that developments such as the advancement of digital technologies, automation, and the movement of manufacturing jobs to low-wage countries will lead to major transformations in the labour market, and some foresee significant job losses. Due to the close relationship between employment and health, major job losses would have significant negative impacts on the health and well-being of individuals an...

Cascaded DBR plasmonic cavity lens for far-field subwavelength imaging at a visible wavelength.

We experimentally demonstrate a novel cascaded plasmonic superlens, which can directly image subwavelength objects with magnification in the far field at a wavelength of 640nm. The lens consists of two plasmonic slabs. One is a plasmonic cavity lens used for near-field coupling, and the other one is a planar plasmonic lens for phase compensation and thus, image magnification. To tune the performance wavelength to visible and to enhance the near-field transmission, distributed Bragg reflectors are integrated...

Predictability in process-based ensemble forecast of influenza.

Process-based models have been used to simulate and forecast a number of nonlinear dynamical systems, including influenza and other infectious diseases. In this work, we evaluate the effects of model initial condition error and stochastic fluctuation on forecast accuracy in a compartmental model of influenza transmission. These two types of errors are found to have qualitatively similar growth patterns during model integration, indicating that dynamic error growth, regardless of source, is a dominant compon...

Attention deficit/hyperactivity disorder and future expectations in Russian adolescents.

In recent years, there has been an increasing focus on the role of future expectations-the extent to which a future outcome is deemed likely-in the health and well-being of adolescents, with research linking future expectations to outcomes such as an increased likelihood of engaging in risky health behaviors. As yet, however, there has been no research on future expectations and attention deficit/hyperactivity disorder (ADHD) in adolescence. To address this research gap, the current study examined the assoc...

Unravelling the link between global rubber price and tropical deforestation in Cambodia.

Tropical forests continue to undergo a rapid transformation. The expansion of rubber tree (Hevea brasiliensis) plantations has been reported as a major driver of forest loss, linked to a boom in market demand. Distant commodity markets have spurred a surge of large-scale economic land concessions granted throughout tropical Southeast Asia. Using satellite imagery, we show the impact of rubber tree plantations on Cambodian forest cover and analyse how annual forest-to-rubber conversion rates relate to global...

Monte Carlo simulation of dose coefficients for a fish eye lens model exposed to monoenergetic electrons.

Vision is an important sense for the majority of the wildlife species, affecting their ability to find food and escape predation. Currently, no study on radiation induced cataract frequency on the fish eyes lens has been done. However, any thorough future study of this subject will require more accurate dose estimates for the fish eye lens than those currently available. For this purpose, the eye lens absorbed dose per unit fluence conversion coefficients for electron irradiation were calculated using the M...

Biomechanics of the human lens and accommodative system: Functional relevance to physiological states.

The ability of the human lens to accommodate is mediated by the ciliary muscle and zonule; the manifest optical power changes depend on the shape and material properties of the lens. The latter are difficult to measure with accuracy and, given the dynamic aspects of accommodation and the ageing of cells and tissues, the biomechanics of the lens is neither fixed nor constant. A range of techniques have been developed to measure both ageing trends and spatial variations in the mechanical properties and these ...
