PHA urges parents to get 'at risk' children vaccinated against seasonal flu

The Public Health Agency is urging Northern Ireland parents to make sure children in 'at risk' groups get their flu vaccine early.The message has been issued to parents and carers of children as the PHA's seasonal flu vaccination programme gets underway for 2011/12.It is very important that children with any condition that puts them more at risk of the complications of flu get the vaccine.These 'at risk' conditions include:chronic lung conditions such as asthma;chest infections that have required hospital admission;chronic heart conditions;chronic liver disease;chronic kidney disease;diabetes;lowered immunity due to disease or treatment such as steroids or cancer therapy;chronic neurological conditions such as stroke, multiple sclerosis or a condition that affects the nervous system, such as cerebral palsy;hereditary and degenerative diseases of the central nervous system or muscles.Children who attend special schools for severe learning or physical disabilities are considered to be particularly at risk, as well as those with other complex health needs.The PHA has written to principals of local special schools, as well as parents of children at these schools, to raise awareness of the importance of getting vaccinated early.Dr Richard Smithson, PHA Flu Vaccination Lead, said: "For many people, flu is a short, unpleasant illness, but it does not usually cause any serious problems. However, for others, it can have very serious complications including, in rare cases, being fatal."We have been particularly reminded over the last two winters that children with chronic neurological problems and other complex health needs are very vulnerable to these complications. We have seen children become very seriously ill and, tragically, there have even been a few deaths in children who attend special schools."For this reason, we recommend that all children who attend special schools for severe learning disability, and special schools for physical disability, are offered the flu vaccine early in the autumn, before the flu viruses start circulating."The vaccine is now available from GP surgeries and the PHA recommends that parents check arrangements with their own GP's surgery so that their child can get the jab.The earlier you get vaccinated the better, as it takes the body about 10-14 days after the jab to develop antibodies. These will then protect you against the same or similar viruses if the body is exposed to them. The vaccine contains three strains of the flu virus, which are considered the most likely to be circulating this winter, including the H1N1 (swine flu) virus."Your child needs to get the flu jab every year - the protection it gives only lasts for one winter, so even if they got it last year, they still need to get it this year," added Dr Smithson."Also, if your child has been diagnosed with flu or swine flu in the past couple of years, they will still need the jab this year as there are different types of flu that the jab will protect against. Getting the flu jab is the best way to protect your child against flu and we would strongly recommend that you arrange for them to have it."Although the vaccine gives good protection, no vaccine gives total protection, so if your child develops flu-like symptoms (such as fever, cough, aches and pains, and sore throat) you should contact your GP for advice. If your child has any of these symptoms, they should be kept at home until they feel better."For more information on seasonal flu, go to www.fluawareni.info and follow us on Facebook and Twitter.

20 years of eosinophilic esophagitis in Olten county: population-based, prospective documentation of an increasing incidence

Background and Aims: Eosinophilic Esophagitis (EoE) is reported with increasing frequency over the last two decades. However, it is still unknown whether this reflects a true increase in incidence or just an increased awareness by gastroenterologists. Therefore, we evaluated the incidence and cumulative prevalence of EoE in Olten county over the last 20 years. Methods: Olten county is an area of approximately 91,000 inhabitants without pronounced demographic changes in the last two decades. EoE evaluation is based upon two gastroenterology centers and one pathology center. No public programs for increased EoE awareness were implemented in this region. All EoE patients diagnosed from 1989 to 2009 were entered prospectively into the Olten county database. Results: Fourty-six patients (76% males, mean age 41±16 yrs) were diagnosed with EoE from 1989 to 2009. Ninety-four percent presented with dysphagia. In 70% of the patients concomitant allergies were found. The number of upper endoscopies per year was stable during the entire observation period. An average annual incidence rate of 2/100,000 was found (range 0-8) with a marked increase in the period from 2001 to 2009. A current cumulative EoE prevalence of 43/100,000 inhabitants was calculated. The mean diagnostic delay (time from first symptoms to diagnosis) was 4.3 years from 1989 to 1998 and 4.8 years from 1999 to 2009. Conclusions: Over the last 20 years, a significant increase in EoE incidence was found in a stable indicator region of Switzerland. The constant rate of upper endoscopies, the constant diagnostic delay, as well as the lack of EoE awareness programs in Olten county indicate a true increase in EoE incidence.

Drug Misuse in Dublin, July 1982

In this report for the Medico Social Research Board the author provides an overview of the drug problem in Dublin's inner city. On 12-14 July 1982 the author visited the Sean Mac Dermott street area of the inner city, the Eastern Health Board, Coolmine Community, Jervis Street Drug Advisory and Treatment Centre and the Garda drug squad. From these interviews, the author concludes that Dublin's inner city has a serious problem with drug use, in particular the injecting of heroin. Heroin addicts steal on a regular basis to fund their habit, and frequently inject themselves in public spaces of local authority flat complexes. Despite the best efforts of the support services (Social workers, doctors, Gardai and clergy) there is a high prevalence of injecting heroin use. There has also been abuse of prescription services. Addicts frequently seek opiates from a small number of doctors who are willing to prescribe. Drug education is severely lacking or inappropriate, according to the author, and the Garda drug squad is severely over stretched. While cannabis use is said to be prevalent in Dublin's two universities, drug use has been most problematic in the deprived parts of the city. The author presents the drug epidemic, which has developed over the last two years, in moral terms, and wonders if Christian society, in particular the Catholic Church, and the health authorities can do anything to stop the crisis from worsening. Recommendations include; conducting epidemiological surveys to determine the true extent of the problem, cross disciplinary co-operation, greater drug awareness through education, and more rehabilitation units.This resource was contributed by The National Documentation Centre on Drug Use.

Escalating epidemiology of eosinophilic esophagitis: 21 years of prospective population-based documentation in Olten county

Background and Aims: Eosinophilic Esophagitis (EoE) is detected with a dramatically increasingfrequency during the last decades. However, it is still unknown whether this reflects atrue increase in incidence or just an increased awareness by gastroenterologists. We therefore,prospectively assessed incidence and prevalence of EoE in an epidemiologically well definedindicator area over the last 21 years. Methods: Olten County is an area of approximately90,000 inhabitants without pronounced demographic changes during the last two decades.Two EoE-experienced gastroenterologists and one pathology centre are responsible forcovering the gastroenterological service of the area. No public programs for increasingawareness of EoE were implemented in this region. Since 1989 all individuals with confirmeddiagnosis of EoE living in Olten County were entered prospectively into the database. Results:Forty-six patients (76% males, mean age 41±16 yrs) were diagnosed with EoE between1989 and 2009. Ninety-four percent of patients presented with dysphagia. An average annualincidence rate of 1.88/100,000 was found (range 0-8) with a marked increase in the periodfrom 2004 to 2009. The cumulative EoE prevalence rose up to 35.1/100,000 inhabitantsin 2009. No significant change was observed for the median diagnostic delay, as it was 3years from 1989 to 1998 and 2 years from 1999 to 2009 with age < 40 years representinga risk factor for retarded diagnosis. The number of upper endoscopies per year increasedby 63% in the period from 1999 to 2009 compared to the years 1989 to 1998 which ismarkedly less then the increase in the incidence rate of 150% for the same periods. Conclusions:Over the last 21 years, a significant increase in EoE incidence and prevalence wasfound in an epidemiologically stable indicator region of Switzerland. The constant diagnosticdelay, the number of newly diagnosed EoE cases that was much more pronounced thanthe modest increase of performed upper endoscopies, as well as the lack of EoE awarenessprograms in Olten County indicates a true increase in EoE incidence.

Epidemiological pattern and mortality rates for hepatitis A in Brazil, 1980-2002: a review

The prevalence of hepatitis A virus (HAV) infection is high in developing countries, in which low standards of sanitation promote the transmission of the virus. In Latin America, which is considered an area of high HAV endemicity, most HAV-positive individuals are infected in early childhood. However, recent studies have shown that prevalence rates are decreasing. Herein, we review the data on HAV prevalence and outbreaks available in scientific databases. We also use official government data in order to evaluate mortality rates in Brazil over the last two decades. Studies conducted in the northernmost regions of Brazil have indicated that, although improved hygiene has led to a reduction in childhood exposure to HAV, the greatest exposure still occurs early in life. In the Southeastern region, the persistence of circulating HAV has generated outbreaks among individuals of low socioeconomic status, despite adequate sanitation. Nationwide, hepatitis A mortality rates declined progressively from 1980 to 2002. During that period, mortality rates in the Northern region consistently exceeded the mean national rate and those for other regions. Excluding the North, the rates in all regions were comparable. Nevertheless, the trend toward decline observed in the South was paralleled by a similar trend in the North.

Review of Ireland's International Education Strategy 2013 - consultation Paper

Investing in Global Relationships: Ireland’s International Education Strategy 2010 – 2015 was published in September 2010. Significant progress has been made in implementing this strategy, to complement and support the work undertaken at institutional level: - A strong national brand is now in place: Education in Ireland, managed by Enterprise Ireland. - There is much closer alignment between education and immigration policies. - A new Government of Ireland Scholarship has been established, managed by the Higher Education Authority. - An International Education Marketing Fund has been developed which allows institutions to collaborate in Enterprise Ireland- led national marketing initiatives. - Promotional efforts are taking place in the priority markets of the USA, Brazil, China, India, SE Asia and the Gulf. Ministers have visited each of the priority markets in the last two years. - Ireland is participating at national level in major international scholarship schemes such as Science Without Borders (Brazil) and the King Abdullah Scholarship Programme (Saudi Arabia). - Statutory provision is now in place for an international education mark and code of practice, which will be rolled out in 2014 by Qualifications and Quality Assurance Ireland (QQI). - International student numbers have risen in priority sectors: 14% growth in the English language sector and 9% growth in higher education since 2010. - Ireland’s international education offering has also diversified, including with increasingly significant levels of cross- border provision. However, global demand for education continues to change rapidly. There continues to be a massive expansion in demand for education around the world, particularly in emerging markets with growing middle classes.

Taenia solium metacestode immunodominant peptides recognized by IgG antibodies in cerebrospinal fluid and serum paired samples from patients with active and inactive neurocysticercosis

The aim of this study was to test if serological distinction between patients with active and inactive neurocysticercosis (NCC), could be accomplished by the recognition of immunodominant peptides in total saline antigenic extract of Taenia solium metacestodes by IgG antibody in cerebrospinal fluid (CSF) and serum paired samples. CSF and serum samples of 10 each, active NCC patients, inactive NCC, and individuals with other neurological disorders, were used to recognize the antigenic peptides by western blot (WB). In the active NCC the 28-32 and 39-42 kDa peptides were more frequently detected in CSF than in sera (p < 0.05). The 47-52, 64-68, and 70 kDa antigens showed high frequencies in both samples from patients with active NCC. All the CSF samples of inactive NCC and other neurological disorder (control) patients tested negative, while serum samples from these last two groups recognized mainly the 80, 86, 95, and 98 kDa bands. This finding eliminates the use of the high molecular weigh bands (> 80 kDa) for diagnosis of NCC. The final conclusions were that the difference between active and inactive NCC may be done with the detection of peptides only in the CSF samples and that the 47-52, 64-68, and 70 kDa bands may be included as specific markers for active NCC when detected in CSF samples by WB using total saline extract of T. solium metacestode.

Aedes aegypti, Aedes albopictus, and dengue in Argentina: current knowledge and future directions

Since the reinfestation of South American countries by Ae. aegypti, dengue fever (DF) and dengue hemorrhagic fever (DHF) have become a major public health concern. The aim of this paper was to review the information related with Aedes vectors and dengue in Argentina since the reintroduction of Ae. aegypti in 1986. The geographic distribution of Ae. albopictus is restricted to the Northeast, and that of Ae. aegypti has expanded towards the South and the West in comparison with the records during the eradication campaign in the 1960s. Since 1998, 4,718 DF cases have been reported concentrated in the provinces of Salta, Formosa, Misiones, Jujuy and Corrientes. Despite the circulation of three dengue virus serotypes (DENV-1, -2 and -3) in the North of the country, DHF has not occurred until the present. The information published over the last two decades regarding mosquito abundance, temporal variations, habitat characteristics, competition, and chemical and biological control, was reviewed. Considering the available information, issues pending in Argentina are discussed. The presence of three DENV, the potential spread of Ae. albopictus, and the predicted climate change suggest that dengue situation will get worse in the region. Research efforts should be increased in the Northern provinces, where DHF is currently an actual risk.

A survey on the enlistment of pharmacists in a hospital battalion of the Swiss Armed Forces

Background: Pharmacists, mainly militiamen, are incorporated in the Swiss Armed Forces, for instance in hospital battalions to supply drugs and medical devices, as well as to coordinate hygiene service. Presently, their duties are only very globally defined. Aims: The objective of this survey was to investigate the tasks that were actually assumed by the military pharmacy of the 2nd Hospital Battalion. Methods: Two types of commitments, offering military and civilian interest's convergence, were considered between 2005 and 2011: (1) army camps for the disabled and (2) operations and supports provided to two nursing homes. While relieving the civil caregiver usually involved with disabled or elderly people, such missions offer indeed the possibility to the army medical service to train its care and logistical processes with real patients, even in the absence of any sanitary crisis or war in the country. Results: Two basis activities have been assumed: (1) centralized supply of drugs and medical devices and (2) coordination of hygiene monitoring and disinfection operations. New tasks were also performed: (3) support to the management of ward-based pharmacies, (4) pillboxes preparation, (5) medication review and (6) selective participation in clinical rounds. The last two were integrated in an interdisciplinary education process. Conclusions: Results shows that, apart from traditional duties, new clinical-oriented activities have been evenly developed and assumed by militia pharmacists. They call thus for a possible renewed definition of the tasks of military hospital pharmacists and of their related military education. A wider study in all hospital battalions is yet mandatory.

La participació en projectes telemàtics : noves oportunitats, nous serveis

La Biblioteca de la Universitat Oberta de Catalunya va començar a funcionar durant el curs 1995-1996. Des d'un bon principi, la singular concepció d'aquesta nova universitat a distància i la manca d'experiències similars en les que basar el desenvolupament dels seus serveis bibliotecaris va fer palesa la necessitat de donar una especial atenció al seguiment i l'aplicació de les noves tecnologies emergents. En els dos anys transcorreguts aquest plantejament s'ha vist consolidat i, en l'actualitat, està incorporat als objectius i a les línies d'actuació de la Biblioteca.

What new cell biology findings could bring to therapeutics: is it time for a phenome-project in Toxoplasma gondii?

"If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat" (SunTzu the Art of War, 544-496 BC). Although written for the managing of conflicts and winning clear victories, this basic guideline can be directly transferred to our battle against apicomplexan parasites and how to focus future basic research in order to transfer the gained knowledge to a therapeutic intervention stratey. Over the last two decades the establishment of several key-technologies, by different groups working on Toxoplasma gondii, made this important human pathogen accessible to modern approaches in molecular cell biology. In fact more and more researchers get attracted to this easy accessible model organism to study specific biological questions, unique to apicomplexans. This fascinating, unique biology might provide us with new therapeutic options in our battle against apicomplexan parasites by finding its Achilles' heel. In this article we argue that in the absence of a powerful high throughput technology for the characterisation of essential gene of interests a coordinated effort should be undertaken to convert our knowledge of the genome into one of the phenome.

A Bayesian network approach to the database serch problem in criminal proceedings

Background The 'database search problem', that is, the strengthening of a case - in terms of probative value - against an individual who is found as a result of a database search, has been approached during the last two decades with substantial mathematical analyses, accompanied by lively debate and centrally opposing conclusions. This represents a challenging obstacle in teaching but also hinders a balanced and coherent discussion of the topic within the wider scientific and legal community. This paper revisits and tracks the associated mathematical analyses in terms of Bayesian networks. Their derivation and discussion for capturing probabilistic arguments that explain the database search problem are outlined in detail. The resulting Bayesian networks offer a distinct view on the main debated issues, along with further clarity. Methods As a general framework for representing and analyzing formal arguments in probabilistic reasoning about uncertain target propositions (that is, whether or not a given individual is the source of a crime stain), this paper relies on graphical probability models, in particular, Bayesian networks. This graphical probability modeling approach is used to capture, within a single model, a series of key variables, such as the number of individuals in a database, the size of the population of potential crime stain sources, and the rarity of the corresponding analytical characteristics in a relevant population. Results This paper demonstrates the feasibility of deriving Bayesian network structures for analyzing, representing, and tracking the database search problem. The output of the proposed models can be shown to agree with existing but exclusively formulaic approaches. Conclusions The proposed Bayesian networks allow one to capture and analyze the currently most well-supported but reputedly counter-intuitive and difficult solution to the database search problem in a way that goes beyond the traditional, purely formulaic expressions. The method's graphical environment, along with its computational and probabilistic architectures, represents a rich package that offers analysts and discussants with additional modes of interaction, concise representation, and coherent communication.

Schistosoma mansoni: magnetic resonance analysis of liver fibrosis according to WHO patterns for ultrasound assessment of schistosomiasis-related morbidity

For the last two decades, ultrasound (US) has been considered a surrogate for the gold standard in the evaluation of liver fibrosis in schistosomiasis. The use of magnetic resonance imaging (MRI) is not yet standardised for diagnosing and grading liver schistosomal fibrosis. The aim of this paper was to analyse MRI using an adaptation of World Health Organization (WHO) patterns for US assessment of schistosomiasis-related morbidity. US and MRI were independently performed in 60 patients (42.1 ± 13.4 years old), including 37 men and 23 women with schistosomiasis. Liver involvement appraised by US and MRI was classified according to the WHO protocol from patterns A-F. Agreement between image methods was evaluated by kappa index (k). The correlation between US and MRI was poor using WHO patterns [k = 0.14; confidence interval (CI) 0.02; 0.26]. Even after grouping image patterns as "A-D", "Dc-E" and "Ec-F", the correlation between US and MRI remained weak (k = 0.39; CI 0.21; 0.58). The magnetic resonance adaptation used in our study did not confirm US classification of WHO patterns for liver fibrosis.

A New Method for ECG Tracking of Persistent Atrial Fibrillation Termination during Stepwise Ablation

Stepwise radiofrequency catheter ablation (step-CA) has become the treatment of choice for the restoration of sinus rhythm (SR) in patients with long-standing persistent atrial fibrillation (pers-AF). Its success rate appears limited as the amount of ablation to achieve long term SR is unknown. Multiple organization indexes (OIs) have been previously developed to track the organization of AF during step-CA, however, with limited success. We report an adaptive method for tracking AF termination (AF-term) based on OIs characterizing the relationship between harmonic components of atrial activity from the surface ECG of AF activity. By computing their relative evolution during the last two steps preceding AF-term, we found that the performance of our OIs was superior to classical indices to track the efficiency of step-CA "en route" to AF-term. Our preliminary results suggest that the gradual synchronization between the fundamental and its first harmonic of AF activity appears as a promising parameter for predicting AF-term during step-CA.

Bodyweight and migration-related differences in motor abilities in preschool children "Ballabeina"

Introduction: Motor abilities in schoolchildren have been decreasing in the last two decades (Bös, 2003, Tomkinson et al., 2003). This may be related to the dramatic increase in overweight and adiposity during the same time period. Children of migrant background are especially affected (Lasserre et al., 2007). But little is known about the relationship between BMI and migration background and motor abilities in preschool children. Methods/Design We carried out a cross-sectional analysis with 665 children (age 5.1 ± 0.6 years; 49.8 % female) of 40 randomly selected kindergarten classes from German and French speaking regions in Switzerland with a high migrant background. We investigated BMI, cardiorespiratory fitness (20 m shuttle run), static (displacement of center of pressure (COP)) and dynamic (balancing forward on a beam) postural control and overall fitness (obstacle course). Results: Of the children, 9.6 % were overweight, 10.5 % were obese (Swiss national percentiles) and 72.8 % were of migrant background (at least one parent born outside of Switzerland). Mean BMI from children of non-migrant background was 15.5 ± 1.1 kg/m2, while migrant children had a mean BMI of 15.8 ± 1.7 kg/m2 (p=0.08). Normal-weight children performed better in cardiorespiratory fitness (3.1 ± 1.4 vs. 2.6 ± 1.1 stages, p<0.001), overall fitness (18.9 ± 4.4 vs. 20.8 ± 4.6 sec, p<0.001) and in dynamic balance (4.9 ± 3.5 vs. 3.8 ± 2.5 steps, p<0.001) compared to overweight and obese children, while the latter had less postural sway (COP: 956 ± 302 vs. 1021 ± 212 mm, p=0.008). There was a clear inverse dose-response relationship between weight status and dynamic motor abilities. There were no significant differences in most tested motor abilities between non-migrant and migrant. The latter performed less well in only one motor test (overall fitness: 20.2 ± 5.2 vs. 18.3 ± 3.5 sec, p<0.001). These findings persisted after adjustment for BMI. Conclusion In preschool children, differences in motor abilities are already present between normal weight and overweight/obese children. However, migrant children demonstrate similar motor abilities compared to non-migrant children for almost all tests, despite their slightly higher BMI.
