Obesity - an acknowledged public health challenge

As we face a difficult economic climate, in which inequalities may worsen, the PHA faces many challenges in its efforts to improve the health of the population. One such challenge is the issue of obesity. Recently, in the Draft Programme for Government and, again today, in anticipation of the publication of the Consultation on the Review of Health and Social Care Services in Northern Ireland, the specific issue of obesity has been highlighted in the media.The PHA is committed to playing a lead role in tackling this major health issue and has been systematically examining the evidence of best practice and effectiveness to ensure that investment and working in partnership will bring clear benefits. A welcome consequence of any success would be a reduction in the impact of the physical, and emotional costs of obesity related ill-health to individuals - and the financial costs to an overstretched healthcare system.A multi-facetted approach to tackling obesity is required for Northern Ireland. This will mean working across government departments, looking at relevant legislation, taxation, food standards and labelling, as well as supporting a raft of programmes within education, workplace, and at the local community level."The prevalence of overweight and obesity has risen dramatically in recent years in Northern Ireland and is now the norm to be overweight, rather than the exception. The Northern Ireland Health and Social Wellbeing Survey (2010-11) indicated that 36% of adults are overweight and a further 23% are obese; this means that approximately 3 in 5 adults in Northern Ireland carry excess weight. A similar proportion of males and females were obese (23%) however males were more likely to be overweight (44%) than females (30%).Data from the Northern Ireland Health and Wellbeing Survey (2010-11) reported that 27% of children aged 2-15 years are obese or overweight. The findings presented here are based on the guidelines put forward by the International Obesity Task Force. Using this approach, 8% of children were assessed as obese, with similar results for boys (8%) and girls (9%). Obesity has serious implications for health and wellbeing and is associated with an increased risk of heart disease and stroke, type 2 diabetes, some cancers, respiratory problems and joint pain.Evidence indicates that being obese can reduce life expectancy by up to 9 years; and it can impact on emotional and psychological well-being and self-esteem, especially among young people.Obesity also impacts on wider society through economic costs, loss of productivity and increased demands on our health and social care system. It is estimated that obesity in Northern Ireland is resulting in 260,000 working days lost each year with a cost to the local economy of £500 million.The good news is that the intentional loss of significant weight (approx 10kg) in overweight and obese adults has been shown to confer significant health benefits, decreased morbidity and may also reduce obesity-related mortality.Key programmes and interventions are undertaken by the PHA in order to prevent and reduce overweight and obesity. The programmes/interventions are supported by significant ongoing work at local level. Examples include:the promotion of breastfeeding; local programmes to increase awareness of good nutrition and develop cooking skills, for example 'Cook It!'; promotion of more active lifestyles, for example, Walking for Health' and 'Teenage Kicks'; development of community allotment schemes; programmes for primary school children, for example Skip2bfit and Eat, Taste and Grow; and sports and other recreation, for example 'Active Belfast'. The PHA's multi media campaign 'It all adds up!' to encourage children to become more active and understand the importance of keeping fit, in a fun and exciting way, ran until October 2011. It encouraged parents and carers to go to the website www.getalifegetactive.com and download the PHA logbook It all adds up! to plan activities as a family. The logbook helped children and parents plan and keep track of their participation in physical activity at school, home and in the community. PHA is currently developing a public information campaign and other supportive work to increase public awareness of obesity as well as to provide advice and support for those who want to make real changes. The campaign development is well underway and is anticipated for launch in late Spring 2012. Like many common health problems, people living in disadvantaged circumstances suffer most and the PHA is committed to tackling this aspect of health inequality. The good news is that even a modest weight loss, of 1-1 Â_ stones, can help to reduce the risk of many of the health problems resulting from being overweight or obese. Information on losing weight through healthier eating and being more active can be found on the PHA websites - www.enjoyhealthyeating.info and www.getalifegetactive.com . These websites provide help and advice for anyone who wants to improve their eating habits and fitness levels, by making small, sustainable, healthy changes to their lifestyle. The PHA leaflet, Small changes, big benefits is also available to download from the PHA website, 'Publications' section.

Escherichia coli variants in periprosthetic joint infection: diagnostic challenges with sessile bacteria and sonication.

The diagnostic yield of prosthetic joint-associated infection is hampered by the phenotypic change of bacteria into a sessile and resistant form, also called biofilm. With sonication, adherent bacteria can be dislodged from the prosthesis. Species identification may be difficult because of their variations in phenotypic appearance and biochemical reaction. We have studied the phenotypic, genotypic, and biochemical properties of Escherichia coli variants isolated from a periprosthetic joint infection. The strains were collected from synovial fluid, periprosthetic tissue, and fluid from the explanted and sonicated prosthesis. Isolates from synovial fluid revealed a normal phenotype, whereas a few variants from periprosthetic tissue and all isolates from sonication fluid showed different morphological features (including small-colony variants). All isolates from sonication fluid were beta-galactosidase negative and nonmotile; most were indole negative. Because of further variations in biochemical properties, species identification was false or not possible in 50% of the isolates included in this study. In contrast to normal phenotypes, variants were resistant to aminoglycosides. Typing of the isolates using pulsed-field gel electrophoresis yielded nonidentical banding patterns, but all strains were assigned to the same clonal origin when compared with 207 unrelated E. coli isolates. The bacteria were repeatedly passaged on culture media and reanalyzed. Thereafter, most variants reverted to normal phenotype and regained their motility and certain biochemical properties. In addition, some variants displayed aminoglycoside susceptibility after reversion. Sonication of an explanted prosthesis allows insight into the lifestyle of bacteria in biofilms. Since sonication fluid also reveals dislodged sessile forms, species identification of such variants may be misleading.

ICT Skills Action Plan 2014-2018

In January 2012, in a direct response to specific skills shortages for people with high-level ICT skills, the Department of Education and Skills published a joint Government–industry ICT Action Plan aimed at building the supply of high-level ICT graduates. One of the key measures in the Plan was the roll-out, from March 2012, of more than 800 places on intensive NFQ level 8 higher diploma ICT skills conversion programmes by higher education providers in partnership with industry. In recognition of the ICT and software development skills shortages that continue to exist, a second phase of the ICT Skills Programme was rolled-out in late 2012, with the Higher Education Authority requesting proposals from higher education providers for a further round of specialist programmes aimed at addressing identified ICT and software development skills gaps. From spring 2013, a number of higher education providers are again offering a number of Level 8 Conversion Programmes, in collaboration with industry partners, which will provide graduates from other skills areas with the opportunity to up-skill or re-skill through a 1 year full-time HDip Conversion Programme in core computing/programming, software and data analysis.

Joint Commissioning Plan 2012-2013

Legislation enacted on 1 April 2009 created a new commissioning system in Northern Ireland with the establishment of a region-wide Health and Social Care Board (including five Local Commissioning Groups (LCGs) and a Public Health Agency).The Health and Social Care Board is required by statute to prepare and publish each year a Commissioning Plan setting out the health and social care services to be commissioned and the associated costs of delivery.This is the�third Commissioning Plan to be produced by the Health and Social Care Board and Public Health Agency. It takes forward and builds upon the key themes set out in the first two Commissioning Plans, in particular tackling health inequalities, reforming acute hospital services, reforming social care services and establishing Primary Care Partnerships.

Free Technology Academy : a Joint Venture of Free Software and OER

The decision to publish educational materials openly and under free licenses brings up the challenge of doing it in a sustainable way. Some lessons can be learned from the business models for production, maintenance and distribution of Free and Open Source Software. The Free Technology Academy (FTA) has taken on these challenges and has implemented some of these models. We briefly review the FTA educational programme, methodologies and organisation, and see to which extent these models are proving successful in the case of the FTA.

Le taux de détresse respiratoire du nouveau-né augmente, celui des césariennes aussi: et si ce n'était pas un hasard? [Respiratory distress of the neonate and the rate of caesarean section have increased over the last 30 years. Is there a link?]

Ces trente dernières années, on note en Suisse une augmentation significative de l'incidence du syndrome de détresse respiratoire (SDR) chez le nouveau-né (NN), touchant particulièrement les enfants avec un poids de naissance >2500 g. En même temps, le taux des césariennes (CS) s'est aussi accru. Une explication pour une éventuelle corrélation entre les deux évolutions est une augmentation en particulier des CS électives qui ont tendance à être planifiées à un terme précoce pour éviter la mise en travail spontanée. Suite à cela, le foetus est privé de différents mécanismes qui favorisent l'adaptation pulmonaire périnatale. Les bénéfices réels de la CS sur la morbidité tant foetale que maternelle ne doivent pas faire oublier que la CS est un facteur de risque pour le SDR du NN. Ce risque peut être diminué efficacement en planifiant une CS élective après 39 semaines révolues. In Switzerland, the rate of respiratory distress in neonates needing hospitalization has doubled over the last thirty years, concerning in particular babies weighing more than 2500 g. In the same time, the rate of Caesarean section (CS) has also multiplied. We suppose that a link between the two evolutions might be the increase of elective CS. They tend to be planned early at term to avoid the onset of spontaneous labour As a consequence, the foetus is deprived of different mechanisms helping pulmonary transition around birth. The potential benefits of CS regarding morbidity of foetus and mother should not overshadow that CS is a significant risk factor for respiratory problems of the neonate. This risk could be dramatically decreased by planning elective CS only after completed 39 weeks of gestation

Dix erreurs a ne pas commettre lors de la prise en charge d'une prothèse articulaire infectée en orthopédie [Ten errors to avoid while dealing with infected total joint arthroplasties].

Infections after total joint arthroplasty are rare but come with severe consequences. Timely, adequate and standardized treatment beginning at the onset of symptoms will have a major impact on the handling of this dreaded complication. In absences of clear guidelines, errors are often committed, with occasionally severe consequences for the patient. In this article, the 10 most frequent errors starting with diagnostics till antibiotic and surgical treatment will be discussed.

Suture repair of umbilical hernia during caesarean section: a case-control study.

PURPOSE: The objective of this study was to investigate the additional burdens in terms of pain, prolongation of surgery and morbidity which is added to elective caesarean section if umbilical hernia suture repair is performed simultaneously. Secondly, patient's satisfaction and hernia recurrence rate were assessed. METHODS: Consecutive women with symptomatic umbilical hernia undergoing internal or external suture repair during elective caesarean were included in this retrospective cohort-control study. Data on post-operative pain, duration of surgery and morbidity of a combined procedure were collected. These patients were matched 1:10 to women undergoing caesarean section only. Additionally, two subgroups were assessed separately: external and internal suture hernia repair. These subgroups were compared for patient's satisfaction, cosmesis, body image and recurrence rate. RESULTS: Fourteen patients with a mean age of 37 years were analysed. Internal suture repair (n = 7) prolonged caesarean section by 20 min (p = 0.001) and external suture repair (n = 7) by 34 min (p < 0.0001). Suture repair did not increase morphine use (0.38 ± 0.2 vs. 0.4 ± 02 mg/kg body weight), had no procedure-related morbidity and prolonged hospitalization by 0.5 days (p = 0.01). At a median follow-up of 37 (5-125) months, two recurrences in each surgical technique, internal and external suture repair, occurred (28 %). Body image and cosmesis score showed a higher level of functioning in internal suture repair (p = 0.02; p = 0.04). DISCUSSION: Despite a high recurrence rate, internal suture repair of a symptomatic umbilical hernia during elective caesarean section should be offered to women if requested. No additional morbidity or scar is added to caesarean section. Internal repair is faster, and cosmetic results are better, additional skin or fascia dissection is avoided, and it seems to be as effective as an external approach. Yet, women must be informed on the high recurrence rate.

Redescription of Anopheles (Nyssorhynchus) antunesi Galvão & Amaral and description of a new species of the Myzorhynchella Section (Diptera: Culicidae) from Serra da Mantiqueira, Brazil

Anopheles (Nyssorhynchus) pristinus Nagaki & Sallum, n. sp. of the Myzorhynchella Section is described based on morphological characters of adult females, males, fourth-instar larvae, pupae and male genitalia. Anopheles (Nyssorhynchus) antunesi Galvão & Amaral is characterized to fix its identity and distinguish it from An. pristinus. The eggs of An. antunesi are described for the first time. Molecular characterization employing sequences of the COI mitochondrial gene and the ITS2 region of ribosomal DNA are provided for each species. An. antunesi and An. pristinus are compared with morphologically similar species of the Myzorhynchella Section. The results of the present study suggest that the new species has been misidentified as both An. antunesi and Anopheles lutzii Cruz. An. antunesi and An. pristinus are sympatric, occurring at high altitudes in Serra da Mantiqueira, Southeastern Brazil.

Magma generation at the easternmost section of the Hellenic arc: Hf, Nd, Pb and Sr isotope geochemistry of Nisyros and Yali volcanoes (Greece)

Geochemical and petrographical studies of lavas and ignimbrites from the Quaternary Nisyros-Yali volcanic system in the easternmost part of the Hellenic arc (Greece) reveal insight into magma generating processes. A compositional gap between 61 and 68 wt.% SiO2 is recognized that coincides with the stratigraphic distinction between pre-caldera and postcaldera volcanic units. Trace element systematics support the subdivision of Nisyros and Yali volcanic units into two distinct suites of rocks. The variation of Nd and Hf present day isotope data and the fact that they are distinct from the isotope compositions of MORB rule out an origin by pure differentiation and require assimilation of a crustal component. Lead isotope ratios of Nisyros and Yali volcanic rocks support mixing of mantle material with a lower crust equivalent. However, Sr-87/Sr-86 ratios of 0.7036-0.7048 are incompatible with a simple binary mixing scenario and give low depleted mantle extraction ages (< 0.1 Ga), in contrast with Pb model ages of 0.3 Ga and Hf and Nd model ages of ca. 0.8 Ga. The budget of fluid-mobile elements Sr and Pb is likely to be dominated by abundant hydrous fluids characterised by mantle-like Sr isotope ratios. Late stage fluids probably were enriched in CO2, needed to explain the high Th concentrations. The occurrence of hydrated minerals (e.g., amphibole) in the first post-caldera unit with the lowermost Sr-87/Sr-86 ratio of 0.7036 +/- 2 can be interpreted as the result of the increased water activity in the source. The presence of two different plagioclase phenocryst generations in the first lava subsequent to the caldera-causing event is indicative for a longer storage time of this magma at a shallower level. A model capable of explaining these observations involves three evolutionary stages. First stage, assimilation of lower crustal material by a primitive magma of mantle origin (as modelled by Nd-Hf isotope systematics). This stage ended by an interruption in replenishment that led to an increase of crystallization and, hence, an increase in viscosity, suppressing eruption. During this time gap, differentiation by fractional crystallization led to enrichment of incompatible species, especially aqueous fluids, to silica depolymerisation and to a decrease in viscosity, finally enabling eruption again in the third stage.

Molecular phylogeny of the Myzorhynchella Section of Anopheles (Nyssorhynchus) (Diptera: Culicidae): genetic support for recently described and resurrected species

Phylogenetic relationships among species of the Myzorhynchella Section of Anopheles (Nyssorhynchus) were investigated using the nuclear ribosomal DNA second internal transcribed spacer (ITS2), the nuclear whitegene and mitochondrial cytochrome oxidase subunit I (COI) regions. The recently described Anopheles pristinus and resurrected Anopheles guarani were also included in the study. Bayesian phylogenetic analyses found Anopheles parvus to be the most distantly related species within the Section, a finding that is consistent with morphology. An. pristinus and An. guarani were clearly resolved from Anopheles antunesi and Anopheles lutzii, respectively. An. lutzii collected in the same mountain range as the type locality were found within a strongly supported clade, whereas individuals from the southern state of Rio Grande do Sul, tentatively identified as An. lutzii based on adult female external morphology, were distinct from An. lutzii, An. antunesi and from each other, and may therefore represent two new sympatric species. A more detailed examination of An. lutzii sensu latoalong its known geographic range is recommended to resolve these anomalous relationships.
