Novel Strategies For Food Risk

Our every day decision-making behaviour relating to food choice is taken in the context of considerations of health, naturalness, economy, convenience and what we perceive as ‘risk’. Risk perception is now as important as any technical assessment of risk. In order to communicate effectively with the consumer about food risks, the importance of the exchange of information and opinions among the interested parties is recognised (FAO/WHO, 1998). Risk communication is “not just a matter of ensuring that one’s messages are delivered and listened to â€_.. also very much a process of empowering individuals â€_. to sharpen the skills necessary to make balanced judgements on risksâ€ù, (Scherer 1991). This safefood review, conducted on an all-island of Ireland basis, provides valuable insights into the perception of food safety risk from consumers on the island of Ireland and the food safety expert viewpoint. It explores the barriers to communicating with consumers on the island of Ireland about food safety risk. It also studies the barriers to promoting and practising good food hygiene - subgroups within the population are identified as being at ‘high risk’ because of inadequate levels of knowledge or more frequently resulting from not believing that the investment of time and effort in good food safety practice is worthwhile.

Directory of Food Safety Laboratory Services

All laboratories play a key role in protecting public health by analysing the microbiological and chemical content of food so that it is safe to eat. On the island of Ireland there are many laboratories & institutions involved in food safety monitoring, surveillance, analysis and research. Some operate directly or are under the aegis of government departments, local and health authorities. Others are privately owned or within third level institutes of higher education and campus companies, and other laboratory establishments are funded or run by various national agencies. These laboratories produce high quality scientific information that benefits public health through routine testing and research encompassing a broad range of foods.

Copwatching et perception publique de la police. L'intervention policière comme performance sous surveillance

Envisagée comme une situation sociale de rassemblement en rue, l'intervention policière se caractérise par sa nature publique et observable. Le « copwatching », en tant que pratique amateur de captation vidéo des interventions de police, problématise la visibilité des agents sur la voie publique en les soumettant à une surveillance médiatique. M'appuyant sur des exemples vidéos, j'explore les dimensions visuelles et symboliques du travail policier. De la performance policière en rue à la figuration médiatique du policier, l'étude des médiations entre action et image permet d'interroger la perception publique de la police engagée dans les rassemblements. Abstract Cop-watching and the public perception of the police. Police intervention as performance under surveillance. This paper deals with police work as a public performance on the street. Cop-watching, a way of publicly observing and documenting police activities, reveals the complex relationship between public perceptions of law enforcement and the visual nature of much police work. Three methodological approaches to cop-watching videos allow us to highlight the visual dimensions of police work : the study of mass-media images of cops, the study of street performance by real cops, and the study of the ways people make sense of the visual symbolic environment present in everyday police work.

Safety and feasibility of NeuroFlo use in eight- to 24-hour ischemic stroke patients.

BACKGROUND: Acute treatment of ischemic stroke patients presenting more than eight-hours after symptom onset remains limited and largely unproven. Partial aortic occlusion using the NeuroFlo catheter can augment cerebral perfusion in animals. We investigated the safety and feasibility of employing this novel catheter to treat ischemic stroke patients eight-hours to 24 h following symptom onset. METHODS: A multicenter, single-arm trial enrolled ischemic stroke patients at nine international academic medical centers. Eligibility included age 18-85 years old, National Institutes of Health stroke scale (NIHSS) score between four and 20, within eight-hours to 24 h after symptom onset, and perfusion-diffusion mismatch confirmed by magnetic resonance imaging. The primary outcome was all adverse events occurring from baseline to 30 days posttreatment. Secondary outcomes included stroke severity on neurological indices through 90 days. This study is registered with ClinicalTrials.gov, number NCT00436592. RESULTS: A total of 26 patients were enrolled. Of these, 25 received treatment (one excluded due to aortic morphology); five (20%) died. Favorable neurological outcome at 90 days (modified Rankin score 0-2 vs. 3-6) was associated with lower baseline NIHSS (P < 0·001) and with longer duration from symptom discovery to treatment. There were no symptomatic intracranial hemorrhages or parenchymal hematomas. Asymptomatic intracranial hemorrhage was visible on computed tomography in 32% and only on microbleed in another 20%. CONCLUSIONS: Partial aortic occlusion using the NeuroFlo catheter, a novel collateral therapeutic strategy, appears safe and feasible in stroke patients eight-hours to 24 h after symptom onset.

Multicenter study on the immunogenicity and safety of two recombinant vaccines against hepatitis B

The immunogenicity and safety of a new recombinant hepatitis B vaccine from the Instituto Butantan (Butang®) were evaluated in a multicenter, double-blind, prospective equivalence study in three centers in Brazil. Engerix B® was the standard vaccine. A total of 3937 subjects were recruited and 2754 (70%) met all protocol criteria at the end of the study. All the subjects were considered healthy and denied having received hepatitis B vaccine before the study. Study subjects who adhered to the protocol were newborn infants (566), children 1 to 10 years old (484), adolescents from 11 to 19 years (740), adults from 20 to 30 years (568), and adults from 31 to 40 years (396). Vaccine was administered in three doses on the schedule 0, 1, and 6 months (newborn infants, adolescents, and adults) or 0, 1, and 7 months (children). Vaccine dose was intramuscular 10 µg (infants, children, and adolescents) or 20 µg (adults). Percent seroprotection (assumed when anti-HBs titers were > 10mIU/ml) and geometric mean titer (mIU/ml) were: newborn infants, 93.7% and 351.1 (Butang®) and 97.5% and 1530.6 (Engerix B®); children, 100% and 3600.0 (Butang®) and 97.7% and 2753.1 (Engerix B®); adolescents, 95.1% and 746.3 (Butang®) and 96% and 1284.3 (Engerix B®); adults 20-30 years old, 91.8% and 453.5 (Butang®) and 95.5% and 1369.0 (Engerix B®); and adults 31-40 years old, 79.8% and 122.7 (Butang®) and 92.4% and 686.2 (Engerix B®). There were no severe adverse events following either vaccine. The study concluded that Butang® was equivalent to Engerix B® in children, and less immunogenic but acceptable for use in newborn infants, adolescents, and young adults.

Accidents and Safety - Ageing in Ireland Fact File No. 14

Accidents and SafetyAlthough the number of deaths caused by accidents has fallen by 37% across all age groups in Ireland over the past twenty years, accidents and falls continue to be relatively common causes of death and injury among older people, often resulting in serious longterm difficulties and even premature death. Consequently, the reduction of accidents in the older population is considered to be an important factor in promoting the general well-being of older people. The 1998 Health Promotion Strategy for Older People, Adding years to life, life to years, which was formulated by the National Council on Ageing and OlderPeople in co-operation with the Department of Health and Children, set a target to reduce the death rate from all accidents and their adverse effects in people aged 65 and over by at least 17% in the year 2005. It also set a target of reducing hospital admissions due to falls in people aged 65 and over by at least 17% in the same year.����

Efficacy And Safety Of Baerveldt Aqueous Shunts In Glaucoma Secondary To Anterior Segment Irradiation, For Uveal Melanoma

Purpose: Elevated IOP is commonly associated with iris and ciliary body melanoma. Traditional management requires the majority of eyes to undergo enucleation. The authors describe the first series of Baerveldt aqueous shunts in eyes with uveal melanoma, treated by total anterior segment irradiation.Methods: 25 consecutive patients with unilateral iris melanoma were prospectively recruited after obtaining informed consent. All patients underwent anterior segment proton beam irradiation, corneal limbal autografts and Baerveldt tube implantation at Jules Gonin Eye Hospital, Lausanne. Postoperative examinations were performed on day 1, weeks 1,3,6,9 and months 3,6,12 and annually thereafter. Success was defined as: IOP </=18mmHg (definition A); IOP </= 21mmHg and 20% reduction in IOP (definition B). All complications were recorded.Results: Mean age was 53; mean follow up, 10.3 months; mean interval to treatment following irradiation, 2.4 years; mean pre-op IOP was 29.9 mmHg; mean post-op IOP 14.1 mmHg; mean pre-op medications 3.0; post-op medications 1.3. Success rates were, definition A: 95%; definition B: 90%. Only11% had minor complications and there were no sight-threatening complications. Aggressive ocular hypertension was observed in the several eyes prior to shunt implantation. Two eyes were enucleated for non-glaucoma related sequelae.Conclusions: Baerveldt aqueous shunts are safe and efficacious following total anterior segment irradiation for uveal melanoma. The novel interdisciplinary approach improved ocular retention rates, offering a promising alternative to current management algorithms.

The perception of touch and the ventral somatosensory pathway.

In humans, touching the skin is known to activate, among others, the contralateral primary somatosensory cortex on the postcentral gyrus together with the bilateral parietal operculum (i.e. the anatomical site of the secondary somatosensory cortex). But which brain regions beyond the postcentral gyrus specifically contribute to the perception of touch remains speculative. In this study we collected structural magnetic resonance imaging scans and neurological examination reports of patients with brain injuries or stroke in the left or right hemisphere, but not in the postcentral gyrus as the entry site of cortical somatosensory processing. Using voxel-based lesion-symptom mapping, we compared patients with impaired touch perception (i.e. hypoaesthesia) to patients without such touch impairments. Patients with hypoaesthesia as compared to control patients differed in one single brain cluster comprising the contralateral parietal operculum together with the anterior and posterior insular cortex, the putamen, as well as subcortical white matter connections reaching ventrally towards prefrontal structures. This finding confirms previous speculations on the 'ventral pathway of somatosensory perception' and causally links these brain structures to the perception of touch.

Is accurate perception of body image associated with appropriate weight-control behavior among adolescents of the Seychelles

BACKGROUND: We examined body image perception and its association with reported weight-control behavior among adolescents in the Seychelles.METHODS: We conducted a school-based survey of 1432 students aging 11-17 years in the Seychelles. Perception of body image was assessed using both a closed-ended question (CEQ) and Stunkard's pictorial silhouettes (SPS). Voluntary attempts to change weight were also assessed.RESULTS: A substantial proportion of the overweight students did not consider themselves as overweight (SPS: 24%, CEQ: 34%), and a substantial proportion of the normal-weight students considered themselves as too thin (SPS: 29%, CEQ: 15%). Logistic regression analysis showed that students with an accurate weight perception were more likely to have appropriate weight-control behavior.CONCLUSIONS: We found that substantial proportions of students had an inaccurate perception of their weight and that weight perception was associated with weight-control behavior. These findings point to forces that can drive the upwards overweight trends.
