Help-Seeking From A Counsellor Or Psychotherapist: A Cross-Sectional Study Of Irish Adults, Damien Cassells

Articles

The factors that contribute towards an individual seeking help from a counsellor or psychotherapist for a mental, nervous or emotional problem are explored in this study. A multivariate logistic regression is applied to analyse data from the 2006 National Psychological Wellbeing and Distress Survey. Individuals living in rural areas and in towns with populations of between 5,000 and 10,000 people are found to be less likely to seek counselling, relative to individuals living in Dublin City. Respondents earning the lowest income were less likely to enter therapy compared with respondents earning the highest, while having private health insurance increased the …

Data Mining Raman Microspectroscopic Responses Of Cells To Drugs In Vitro Using Multivariate Curve Resolution-Alternating Least Squares, David Perez-Guaita, Guillermo Quintas, Zeineb Farhane, Roma Tauler, Hugh Byrne

Articles

Raman microspectroscopy is gaining popularity for the analysis of time-dependent biological processes such as drug uptake and cellular response. It is a label-free technique which acquires signals from a large variety of components, including cell biomolecules and exogenous compounds such as drugs and nanoparticles, and is commonly employed for in vitro analysis of cells and cell populations with no labelling or staining required. By monitoring the changes to the Raman spectra of the cell as a result of a perturbing agent (e.g. inoculation of a drug or toxic agent), one can study the associated changes in cell biochemistry involved in …

In this convenience sample, 106 people answered an online questionnaire regarding folate intake and awareness among vegetarians. This was created using Google Forms and was shared via Facebook, including on various national and college vegetarian group pages. There were 44 questions. Twenty-four participants were excluded, because they reported eating fish, chicken or other meat. Final data analysis included 82 subjects. The majority of these vegetarians were females over the …

Seaweeds As Nutraceuticals For Health And Nutrition, Emer Shannon, Nissreen Abu-Ghannam

Articles

Throughout human history, seaweeds have been used as food, folk remedies, dyes, and as mineral-rich fertilisers. Seaweeds as nutraceuticals or functional foods with dietary benefits beyond their fundamental macronutrient content are now a major research and industrial development concept. The occurrence of dietary and lifestyle related diseases, notably type 2 diabetes, obesity, cancer, and metabolic syndrome has become a health epidemic in developed countries. Global epidemiological studies have shown that countries where seaweed is consumed on a regular basis have significantly fewer instances of obesity and dietary-related disease. This review outlines recent developments in seaweed applications for human health from …

Association Of Total Zinc Intake With Myopia In U.S. Children And Adolescents, Niamh Burke, John Butler, Daniel Ian Flitcroft, Daniel Mccartney, James Loughman

Articles

Significance: This present study advances our knowledge on the role of lifestyle factors in myopia (short-sightedness), specifically dietary factors. It has been suggested in previous studies that lower zinc status is associated with myopia; however, this article shows no relationship between dietary zinc intake and myopia in U.S. adolescents. Purpose: It has been suggested that low zinc levels may contribute to the development of myopia. The aim of the present study is to examine, for the first time in a Western population, the association of total dietary and supplement zinc intake with myopia. Methods: A total of 1095 children/adolescents aged …

Virtual Dissection Of White Matter Tracts In A Human Brain Using Applied Game Design And Virtual Reality Imaging, Basil Lim, Anurag Nasa, Nicola Carswell, Elena Roman, Malia Kissner, Darren W. Roddy, Veronika O'Keane, James Carswell

Other

Visualisation of neural tracts in the human brain has previously been accomplished using two dimensional (2D) representational formats. In most cases, pre-operative visualisation is through the medium of 2D MRI image slices, representing coordinates in the brain through a combination of axial, sagittal, and coronal orthographic viewpoints. Software such as ExploreDTI can visualise off-axis viewpoints, however this method is limited to 2.5D image representations. The use of such 2D representations can require significant training in order to contextualise real-world 3D positions and accurately locate and identify neural tract pathways in the brain. Utilising anonymised tract data and advanced neuroimaging technologies …

Integration Of Technology In The Chemistry Classroom And Laboratory, Barry J. Ryan

Books/Book Chapters/ Proceedings

The role of technology in the chemistry classroom and laboratory continues to evolve, with mainstream applications such as pre-lecture/laboratory resources being supplemented by technological innovations such as immersive reality. Although the range is vast, care must be taken to select appropriate and pedagogically aligned technologies to enable learning.

In this chapter a model for the appropriate selection and application of technology enabled learning in chemistry is developed and explored in the context of two case-studies. This model, LEAPTech, is based on ten years of personal experience, informed by evidence and underpinned by the scholarly literature. This model will serve as …

Prevalence Of Ametropia, Amblyopia And Visual Impairment In Schoolchildren In Ireland, Siofra Harrington

Doctoral

Background: Uncorrected refractive error is an avoidable cause of visual impairment (Naidoo et al., 2016). Currently, there is a lack of adequate data on eye and vision disorders in schoolchildren in Ireland. Accurate prevalence estimates of refractive error and vision disorders are necessary to determine their impact on public health and to assess the need for interventions (McCarty and Taylor, 2000). Purpose: This study reports the prevalence of ametropia, presenting visual impairment, amblyopia and provides population norms for ocular biometric measures in schoolchildren in Ireland. Links between refractive error and demographic and lifestyle factors were investigated. The impact of poor …

The Generation Of Novel Metal-Folate- Phenanthroline Complexes And Phenanthroline-Folate Conjugates With Potential As Chemotherapeutic Agents, Aisling Crowley

Doctoral

The folate receptor (FR) was identified in 1986 and has been established as a ‘molecular Trojan Horse’ target for the uptake of folate-conjugated organic molecules into cells. The FR is overexpressed in many malignancies, including those of the ovary, uterus, breast, cervix, and prostate, yet it is reportedly under-expressed in normal healthy cells. This difference in expression and the high affinity/specificity of folate towards the folate receptor presents a promising drug delivery system. The aim of this research was to utilise folic acid as a targeting moiety and generate simple metal folate and novel folate-phenanthroline complexes with cytotoxic properties. A …

An Investigation Of The Detection Capability Of Pulsed Wave Duplex Doppler Of Low Grade Stenosis Using Ultrasound Contrast Agent Microbubbles – An In-Vitro Study, Jacinta Browne, Deirdre King, Andrew Fagan, Deepa Chari, Carmel Moran

Articles

Objective: The objective of the study was to investigate whether clinically used ultrasonic contrast agents improved the accuracy of spectral Doppler ultrasound in the detection of low grade (< 50%) renal artery stenosis. Low grade stenoses in the renal artery are notoriously difficult to reliably detect using Doppler ultrasound due to difficulties such as overlying fat and bowel gas.

Methods: A range of anatomically-realistic renal artery phantoms with varying low degrees of stenosis (0, 30 and 50%) were constructed and peak velocity data was measured from within the pre-stenotic and mid-stenotic regions in each phantom, for both unenhanced and contrast-enhanced spectral Doppler data acquisitions. The effect of a 20mm overlying fat layer on the ultrasound beam distortion and phase aberration, and hence on the measured peak velocity data, was also …

Air Quality Modelling For Ireland, Aoife Donnelly, Bruce Misstear, Brian Broderick

Reports

Air pollution is the primary environmental cause of premature death in the EU (European Commission, 2013) and the most problematic pollutants across Europe have consistently been oxides of nitrogen (e.g. nitrogen dioxide (NO₂)), particulate matter (e.g. PM₁₀, PM_2.5) and ozone (O₃). While measurements form an important aspect of air quality assessment, on their own they are unlikely to be sufficient to provide an accurate spatial and temporal description of the pollutant concentrations for exposure assessment and moreover they cannot provide information regarding future air quality. Annex XVI of 2008/50/EC requires member states …

A U-Net Deep Learning Framework For High Performance Vessel Segmentation In Paitents With Cerebrovascular Disease, Michelle Livne, Jana Rieger, Orhun Utku Aydin, Abdel Aziz Taha, Ela Maria Akay, Tabea Kossen, Jan Sobesky, John D. Kelleher, Kristian Hildebrand, Dietmar Frey, Vince I. Madai

Articles

Brain vessel status is a promising biomarker for better prevention and treatment in cerebrovascular disease. However, classic rule-based vessel segmentation algorithms need to be hand-crafted and are insufficiently validated. A specialized deep learning method—the U-net—is a promising alternative. Using labeled data from 66 patients with cerebrovascular disease, the U-net framework was optimized and evaluated with three metrics: Dice coefficient, 95% Hausdorff distance (95HD) and average Hausdorff distance (AVD). The model performance was compared with the traditional segmentation method of graph-cuts. Training and reconstruction was performed using 2D patches. A full and a reduced architecture with less parameters were trained. We …

Articles

Purpose: This study evaluated the training and assessment role of anthropomorphic breast ultrasound phantoms which simulated both the morphological and sonographic characteristics of breast tissue, including lesions, in a group of radiology residents at a large academic medical center. Methods: This was a prospective study involving 9 residents across all years (2^nd–4^th year) of a radiology residency program. Baseline assessments of all residents ability to detect and characterize lesions in P-I were carried out, followed by a two-hour teaching session on the same phantom. All residents underwent a post-training, final assessment on P-II to evaluate changes in …

Is Optometry Ready For Myopia Control? Education And Other Barriers To The Treatment Of Myopia, Saoirse Mccrann, Daniel Ian Flitcroft, James Loughman

Other Resources

Background

With the increasing prevalence of myopia there is growing interest in active myopia control. However, the majority of progressive myopes are still prescribed single vision spectacles. This prospective study aims to elucidate the knowledge and attitudes of optometrists toward myopia control, and thereby identify perceived barriers to the implementation of a risk focussed model of myopia management.

Methods

A series of four focus group discussions were conducted involving optometrists in different settings and career stages.

Results

The key finding to emerge is a clear disconnect between academic optometrists, optometry students and clinicians in practice. Academic faculty considered themselves competent …

Urban Aerobiological Risk Mapping Of Ornamental Trees Using A New Index Based On Lidar And Kriging: A Case Study Of Plane Trees, Raúl Pecero-Casimiro, Santiago Fernández-Rodríguez, Rafael Tormo-Molina, Alejandro Monroy-Colín, Inmaculada Silva-Palacios, Juan Pedro Cortés-Pérez, Ángela Gonzalo-Garijo, J. M. Maya-Manzano

Articles

Ornamental trees bring benefits for human health, including reducing urban pollution. However, some species, such as plane trees (Platanus sp.), produce allergenic pollen. Consequently, urban maps are a valuable tool for allergic patients and allergists, but they often fail to include variables that contribute to the “building downwash effect”, such as the width and shape of streets and the height of buildings. Other factors that directly influence pollen dispersion (slopes and other geographical features) also have not traditionally been discussed. The LiDAR (Laser Imaging Detection and Ranging) technique enables one to consider these variables with high accuracy. This work proposes …
