Obesity Weighting up the Evidence: All-Island Multisectoral Conference on Obesity

The World Health Organization reports that overweight and obesity have reached epidemic proportions globally and estimates that approximately 1.6 billion adults and at least 20 million children under the age of five are overweight or obese. It is accepted that being overweight or obese increases the risk of health conditions such as heart disease, stroke, diabetes and some cancers and has significant impacts on a wide range of other factors including education, employment and emotional wellbeing. This conference aimed to present a multisectoral audience with the latest developments in overweight and obesity prevention and management. This presentation was given by Dr. Kevin Balanda, Institute of Public Health in Ireland. The Institute of Public Health in Ireland (IPH) is leading the development of an All-Ireland obesity observatory The obesity observatory development is being undertaken in collaboration with: - HRB Centre for Health and Diet Research ﾖ UCC /UCD - Centre of Excellence for Public Health (NI) - QUB Projected outcomes: Adequate sample size Data to be sought and recorded Usefulness of a database in influencing policy Value to clinicians in management of obesity

All-Ireland Health Data Inventory. Part 1: Metadata for key data sources, version 1.0

The All-Ireland Health Data Inventory. Part 1 is a catalogue of key sources of health data in the Republic and Northern Ireland. It includes relevant datasets from the major information reviews, conducted in the North and South, in the past few years. Information is essential for informed decision making and service provision. This inventory draws together information sources to facilitate such decision making. The inventory is intended as a resource for health professionals, researchers and the general public, providing the first phase of a ‘one-stop’ catalogue of health data. The datasets have been catalogued using an expanding numbering system which will allow for the inclusion of future resources. The Institute of Public Health in Ireland is in the process of expanding the Inventory to include further data sources.

IPH response to DHSSPS obesity prevention framework consultation 'A Fitter Future for All'

Preventing obesity is a key priority for the Department of Health, Social Services and Public Safety (DHSSPS) in Northern Ireland. In support of this, the DHSSPS has led the development of a cross-Departmental, crosssectoral Obesity Prevention Framework for Northern Ireland 2011-2021, entitled A Fitter Future For All, which seeks to reduce the prevalence of overweight and obesity throughout  Northern Ireland. The Framework focuses action on three main pillars: food & nutrition; physical activity; and data and research, and within the context of three life course stages: Early Years; Children and Young People; and Adults. This approach is consistent with the responses being undertaken by a number of countries, following the Foresight Report.

A Tobacco-Free Future - An all-island report on tobacco, inequalities and childhood 2013

A Tobacco-Free Future - An all-island report on tobacco, inequalities and childhood 2013 reveals declines in smoking rates among both children and pregnant women over the past decade, both North and South of the border. This report published by the Institute of Public Health in Ireland (IPH) and the TobaccoFree Research Institute Ireland (TFRI), shows that while tobacco control measures are being successful, disadvantaged children are at particular risk of tobacco-related harms.

A Fitter Future for All: Consultation Document

The prevalence of people who are overweight and obese has been steadily rising in Northern Ireland, and in the western world, over the last few decades. It has been described as an “obesity time-bomb”, given the impact that obesity can have on physical and mental health and wellbeing.Evidence has shown that, while weight gain is the result of a relatively simple energy imbalance, the causes that underpin changes to energy intake and expenditure are very complex and cover issues such as social and individual psychology, physiology, food production and consumption, individual activity, and the built environment.This Framework aims to “empower the population of Northern Ireland to make healthy choices, and reduce the level of harm related to overweight and obesity, by creating an environment that supports and promotes a physically active lifestyle and a healthy diet”.In addition, the following overarching target has been set: to reduce the level of obesity in Northern Ireland to the 2005-06 level by 2021.

Framework for Preventing and Addressing Overweight and Obesity in Northern Ireland 2012-2022: A Fitter Future for All (PDF 1MB)

A Framework for Preventing and Addressing Overweight and Obesity in NI 2012-2022 This Framework aims to “empower the population of Northern Ireland to make healthy choices, reduce the risk of overweight and obesity related diseases and improve health and wellbeing, by creating an environment that supports and promotes a physically active lifestyle and a healthy diet”. In addition, the following overarching targets have been set: Adults • To reduce the level of obesity by 4% and overweight and obesity by 3% by 2022. Children • A 3% reduction of obesity and 2% reduction of overweight and obesity by 2022åÊThe target is in two parts; the proportion that are obese and the proportion that are overweight and obese. Prevention is typically taken forward through action to address two main areas – improving diet and nutrition, and increasing participation in physical activity. Acknowledging this, two overarching objectives for the Framework have been set: to increase the percentage of people eating a healthy, nutritionally balanced diet; and to increase the percentage of the population meeting the CMO guidelines on physical activity.

Factors that can interfere with virus concentration from wastewater when using zeta plus 60S filter membranes

Zeta plus filter membranes (ZP60S) have been shown to be efficient for rotavirus concentration from wastewater and for the reduction of cytotoxicity for cell cultures. Recently a variability in both properties was observed. In view of the low costs and the high virus recovery rates obtained in the past, we re-evaluated the application of ZP60S filter membranes for virus concentration from environmental samples. Some factors that could interfere with the concentration strategy using ZP60S were also considered and assessed including the type of water to be filtered and the possible release of toxic substances from the membrane matrix during filtration.

Age-specific incidence of all neoplasms after colorectal cancer.

PURPOSE: Patients diagnosed with a specific neoplasm tend to have a subsequent excess risk of the same neoplasm. The age incidence of a second neoplasm at the same site is approximately constant with age, and consequently the relative risk is greater at younger age. It is unclear whether such a line of reasoning can be extended from a specific neoplasm to the incidence of all neoplasms in subjects diagnosed with a defined neoplasm. METHODS: We considered the age-specific incidence of all non-hormone-related epithelial neoplasms after a first primary colorectal cancer (n = 9542) in the Vaud Cancer Registry data set. RESULTS: In subjects with a previous colorectal cancer, the incidence rate of all other epithelial non-hormone-related cancers was stable around 800 per 100,000 between age 30 and 60 years, and rose only about twofold to reach 1685 at age 70 to 79 years and 1826 per 100,000 at age 80 years or older. After excluding synchronous cancers, the rise was only about 1.5-fold, that is, from about 700 to 1000. In the general population, the incidence rate of all epithelial non-hormone-related cancers was 29 per 100,000 at age 30 to 39 years, and rose 30-fold to 883 per 100,000 at age 70 to 79 years. Excluding colorectal cancers, the rise of all non-hormone-related cancers was from 360 per 100,000 at age 40 to 49 years to 940 at age 70 to 79 years after colorectal cancer, and from 90 to 636 per 100,000 in the general population (i.e., 2.6- vs. 7.1-fold). CONCLUSIONS: The rise of incidence with age of all epithelial non-hormone-related second cancers after colorectal cancer is much smaller than in the general population. This can possibly be related to the occurrence of a single mutational event in a population of susceptible individuals, although alternative models are plausible within the complexity of the process of carcinogenesis.

Forces de Casimir i les seves aplicacions

Report for the scientific sojourn carried out at the Darmouth College, from august 2007 until february 2008. It has been very successful, from different viewpoints: scientific, philosophical, human. We have definitely advanced, during the past six months, towards the comprehension of the behaviour of the fluctuations of the quantum vacuum in the presence of boundaries, moving and non-moving, and also in situations where the topology of space-time changes: the dynamical Casimir effect, regularization problems, particle creation statistics, according to different BC, etc. We have solved some longstanding problems and got in this subject quite remarkable results (as we will explain in more detail below). We also pursued a general approach towards a viable modified f(R) gravity in both the Jordan and the Einstein frames (which are known to be mathematically equivalent, but physically not so). A class of exponential, realistic modified gravities has been introduced by us and investigated with care. Special focus was made on step-class models, most promising from the phenomenological viewpoint and which provide a natural way to classify all viable modified gravities. One- and two-steps models were considered, but the analysis is extensible to N-step models. Both inflation in the early universe and the onset of recent accelerated expansion arise in these models in a natural, unified way, what makes them very promising. Moreover, it is monstrated in our work that models in this category easily pass all local tests, including stability of spherical body solution, non-violation of Newton's law, and generation of a very heavy positive mass for the additional scalar degree of freedom.

Vertical human immunodeficiency virus type 1 - HIV-1 -transmission - a review

Several factors appear to affect vertical HIV-1 transmission, dependent mainly on characteristics of the mother (extent of immunodeficiency, co-infections, risk behaviour, nutritional status, immune response, genetical make-up), but also of the virus (phenotype, tropism) and, possibly, of the child (genetical make-up). This complex situation is compounded by the fact that the virus may have the whole gestation period, apart from variable periods between membrane rupture and birth and the breast-feeding period, to pass from the mother to the infant. It seems probable that an extensive interplay of all factors occurs, and that some factors may be more important during specific periods and other factors in other periods. Factors predominant in protection against in utero transmission may be less important for peri-natal transmission, and probably quite different from those that predominantly affect transmission by mothers milk. For instance, cytotoxic T lymphocytes will probably be unable to exert any effect during breast-feeding, while neutralizing antibodies will be unable to protect transmission by HIV transmitted through infected cells. Furthermore, some responses may be capable of controlling transmission of determined virus types, while being inadequate for controlling others. As occurence of mixed infections and recombination of HIV-1 types is a known fact, it does not appear possible to prevent vertical HIV-1 transmission by reinforcing just one of the factors, and probably a general strategy including all known factors must be used. Recent reports have brought information on vertical HIV-1 transmission in a variety of research fields, which will have to be considered in conjunction as background for specific studies.

tagO is involved in the synthesis of all anionic cell-wall polymers in Bacillus subtilis 168.

Sequence homologies suggest that the Bacillus subtilis 168 tagO gene encodes UDP-N-acetylglucosamine:undecaprenyl-P N-acetylglucosaminyl 1-P transferase, the enzyme responsible for catalysing the first step in the synthesis of the teichoic acid linkage unit, i.e. the formation of undecaprenyl-PP-N-acetylglucosamine. Inhibition of tagO expression mediated by an IPTG-inducible P(spac) promoter led to the development of a coccoid cell morphology, a feature characteristic of mutants blocked in teichoic acid synthesis. Indeed, analyses of the cell-wall phosphate content, as well as the incorporation of radioactively labelled precursors, revealed that the synthesis of poly(glycerol phosphate) and poly(glucosyl N-acetylgalactosamine 1-phosphate), the two strain 168 teichoic acids known to share the same linkage unit, was affected. Surprisingly, under phosphate limitation, deficiency of TagO precludes the synthesis of teichuronic acid, which is normally induced under these conditions. The regulatory region of tagO, containing two partly overlapping sigma(A)-controlled promoters, is similar to that of sigA, the gene encoding the major sigma factor responsible for growth. Here, the authors discuss the possibility that TagO may represent a pivotal element in the multi-enzyme complexes responsible for the synthesis of anionic cell-wall polymers, and that it may play one of the key roles in balanced cell growth.
