Sample records for age retrospective surveillance

  1. Environmental radiological surveillance in retrospect for Kakrapar Atomic Power Station

    International Nuclear Information System (INIS)

    Environmental radiological surveillance carried-out at Kakrapar Atomic Power Station (KAPS) site since 1992 is described in the paper. The radiation exposure of members of the public is mainly due to intake of tritium by ingestion and inhalation and skin absorption routes. The gaseous effluent containing tritiated water vapours is discharged through 100 m stack and low level liquid effluent along with cooling tower blow down water is discharged into Moticher lake. The dose through gaseous route is one third of the dose through aquatic route at this site. The irrigation canal outflowing from Moticher lake carrying diluted aquatic releases flow through WSW sector only, so the ingestion dose is mainly in this sector and contribution in other remaining fifteen sectors is lower by a factor of 4 to 5. The highest annual dose due to tritium during the period even in 1.6 to 5 km zone is 2.3 uSv during 1997, which is only 0.8 % of dose limit of 300 uSv/year apportioned by the station. The concentration of biologically significant long lived radionuclides in diet components like milk, vegetables, cereals, pulses etc that are locally produced and consumed by the general public, are at global fallout levels. The station operation practically does not contribute in this vector. (author)

    In Germany, rabies in bats is a notifiable zoonotic disease, which is caused by European bat lyssaviruses type 1 and 2 (EBLV-1 and 2), and the recently discovered new lyssavirus species Bokeloh bat lyssavirus (BBLV). As the understanding of bat rabies in insectivorous bat species is limited, in addition to routine bat rabies diagnosis, an enhanced passive surveillance study, i.e. the retrospective investigation of dead bats that had not been tested for rabies, was initiated in 1998 to study t...

  3. Surveillance program and aging management at ETRR-II

    International Nuclear Information System (INIS)

    Surveillance program, periodic testing, and in-service inspection are tools to manage the aging of the research reactors and keep the operation of the research reactors within its design, safety analysis, and operational limits and conditions (OLC's) for the lifetime of the research reactor. This paper describes the surveillance program and aging management of the most important systems, structures, and components (SSC's) of the second research reactor of Egypt (ETRR-II). We believe that the exchange of information and discussion between the members states, about this topic, can lead to the best practice for the research reactor surveillance and aging management. It is important for the members states to try to find benchmarking measures for this topic to make the aging management and surveillance program measurable and achievable. (author)

    This thesis aims to explore how prospective and retrospective memory are affected by health in old age. In this regard, we have focused on dementia disorders, depressive symptomatology, and thyroid functions. Prospective memory involves remembering to perform actions, such as paying bills or taking one s medication. Retrospective memory involves remembering previous events or previously learned information, such as the content of a book. The memory process can be divided int...

    Primary hypokalemic periodic paralysis is a familial channelopathy inherited as an autosomal dominant trait. The first attack of paralysis may be evolved at any age, but has been reported to be most common in the second decade, so that some authorities believe that an episodic weakness beginning after age 25 is almost never due to primary periodic paralysis. In this retrospective study, we reviewed 50 patients admitted in two hospitals of Tehran University of Medical Sciences during 1992-2001...

    Full Text Available In Germany, rabies in bats is a notifiable zoonotic disease, which is caused by European bat lyssaviruses type 1 and 2 (EBLV-1 and 2, and the recently discovered new lyssavirus species Bokeloh bat lyssavirus (BBLV. As the understanding of bat rabies in insectivorous bat species is limited, in addition to routine bat rabies diagnosis, an enhanced passive surveillance study, i.e. the retrospective investigation of dead bats that had not been tested for rabies, was initiated in 1998 to study the distribution, abundance and epidemiology of lyssavirus infections in bats from Germany. A total number of 5478 individuals representing 21 bat species within two families were included in this study. The Noctule bat (Nyctalus noctula and the Common pipistrelle (Pipistrellus pipistrellus represented the most specimens submitted. Of all investigated bats, 1.17% tested positive for lyssaviruses using the fluorescent antibody test (FAT. The vast majority of positive cases was identified as EBLV-1, predominately associated with the Serotine bat (Eptesicus serotinus. However, rabies cases in other species, i.e. Nathusius' pipistrelle bat (Pipistrellus nathusii, P. pipistrellus and Brown long-eared bat (Plecotus auritus were also characterized as EBLV-1. In contrast, EBLV-2 was isolated from three Daubenton's bats (Myotis daubentonii. These three cases contribute significantly to the understanding of EBLV-2 infections in Germany as only one case had been reported prior to this study. This enhanced passive surveillance indicated that besides known reservoir species, further bat species are affected by lyssavirus infections. Given the increasing diversity of lyssaviruses and bats as reservoir host species worldwide, lyssavirus positive specimens, i.e. both bat and virus need to be confirmed by molecular techniques.

    Full Text Available Objectives: The aim of this study was to characterize tinnitus in affected patients. Methods: A retrospective review of medical records from 470 consecutive patients who visited a tertiary care hospital for evaluation of chronic subjective tinnitus between January 2009 and June 2010 was performed. Patients were divided into three subgroups based on age. Clinical, audiological, and psychological characteristics of each subgroup were analyzed. Results: Of the 470 patients evaluated, 85 were less than 40, 217 between 40 and 60, and 168 above 60 years of age. Most patients were men and complained of unilateral, acute high-pitched tinnitus. Most patients above the age of 40 years complained of loud and annoying tinnitus and had worse stress and severity scores. Conclusions: Chronic tinnitus in older adults is subjectively louder, more annoying, and more distressing than that found in younger patients. We recommend considering age in the patient management plan.

    Surveillance of notifiable avian influenza (NAI) virus is mandatory in European member states, and each year a serological survey is performed to detect H5 and H7 circulation in poultry holdings. In Belgium, this serological monitoring is a combination of a stratified and a risk-based approach and is applied to commercial holdings with more than 200 birds. Moreover, a competitive nucleoprotein (NP) ELISA has been used as first screening method since 2010. A retrospective analysis of the serological monitoring performed from 2007 through 2013 showed sporadic circulation of notifiable low-pathogenicity avian influenza (LPAI) viruses in Belgian holdings with a fluctuating apparent flock seroprevalence according to years and species. Overall, the highest apparent flock seroprevalence was detected for the H5 subtype in domestic Anatidae, with 20%-50% for breeding geese and 4%-9% for fattening ducks. Positive serology against non-H5/H7 viruses was also observed in the same species with the use of the IDScreen influenza A antibody competition ELISA kit (ID-vet NP ELISA), and confirmed by isolation of H2, H3, H6, and H9 LPAI viruses. Among Galliformes, the apparent flock seroprevalence was lower, ranging between 0.3% and 1.3%. Circulation of notifiable LPAI viruses was only observed in laying hens with a similar seroprevalence for H5 and H7. Based on ID-vet NP ELISA results, no circulation of LPAI viruses, regardless the subtype, was observed in breeding chickens and fattening turkeys. Retrospectively, the use of an ELISA as first-line test not only reduced the number of hemagglutination inhibition tests to be performed, but also gave a broader evaluation of the prevalence of LPAI viruses in general, and might help to identify the most at-risk farms.

The first attack of paralysis may be evolved at any age, but has been reported to be most common in the second decade, so that some authorities believe that an episodic weakness beginning after age 25 is almost never due to primary periodic paralysis. In this retrospective study, we reviewed 50 patients admitted in two hospitals of Tehran University of Medical Sciences during 1992-2001 with acute flaccid weakness and hypokalemia, twenty-three of whom fulfilled our inclusion and exclusion criteria. Two patients showed first attack below age 15, 8 in 15-20, 4 in 20-25, 3 in 25-35, 4 in 35-45, and 2 beyond age 45. In our study, in contrast to previous ones, the first attack was beyond age 20 in 13 patients (56.5% and beyond 25 in 9 (39 %. Age at first attack is more than other studies, which seems to be due to a difference between our epidemiological characteristics compared to that in the West. In other words, in our epidemiological condition, periodic weakness, although started beyond second decade of age, could be due to primary periodic paralysis if secondary hypokalemia had been ruled out.

    Antimicrobial resistance is closely linked to antimicrobial use and is a growing concern worldwide. Antimicrobial resistance increases healthcare costs substantially in many countries, including Lebanon. National data from Lebanon have, in the most part, been limited to a few academic hospitals. The Lebanese Society of Infectious Diseases conducted a retrospective study to better describe the antimicrobial susceptibility patterns of bacterial isolates in Lebanon. Data were based on records retrieved from the bacteriology laboratories of 16 different Lebanese hospitals between January 2011 and December 2013. The susceptibility results of a total 20684 Gram-positive and 55594 Gram-negative bacteria were analyzed. The prevalence rate of methicillin-resistant Staphylococcus aureus was 27.6% and of vancomycin-resistant Enterococcus spp was 1%. Streptococcus pneumoniae had susceptibilities of 46% to oxacillin, 63% to erythromycin, and 98% to levofloxacin. Streptococcus pyogenes had susceptibilities of 94% to erythromycin and 95% to clindamycin. The mean ampicillin susceptibility of Haemophilus influenzae, Salmonella spp, and Shigella spp isolates was 79%, 81.3%, and 62.2%, respectively. The extended-spectrum beta-lactamase production rate for Escherichia coli was 32.3% and for Klebsiella spp was 29.2%. Acinetobacter spp showed high resistance to most antimicrobials, with low resistance to colistin (17.1%). Pseudomonas spp susceptibilities to piperacillin-tazobactam and imipenem were lower than 80% (79.7% and 72.8%, respectively). This study provides population-specific data that are valuable in guiding antimicrobial use in Lebanon and neighbouring countries and will help in the establishment of a surveillance system for antimicrobial resistance following the implementation of a nationwide standardization of laboratory methods and data entry.

    Futuna is a small Polynesian island in the South Pacific with a population of 3,612 in 2013. The first human leptospirosis case was confirmed in 1997. Active surveillance started in 2004. Cases were confirmed by PCR or real time PCR, or by serology using MAT or a combination of IgM-ELISA and MAT. A retrospective analysis of surveillance data shows that the disease was endemic with a mean annual incidence of 844 cases per 100,000 over an 11-year period from 2004 to 2014. An epidemic peak as high as 1,945 cases per 100,000 occurred in 2008. Serogroup Australis was predominant until 2007, Icterohaemorrhagiae was dominant afterwards. Cluster analysis revealed different hot spots over time. Lifestyle habits, such as walking barefoot in irrigated taro fields or pig pens probably contributed to contamination from the swine and rodent reservoirs to humans. Severe forms were rare, and the case fatality rate was 0.5%. The medical community and general population were aware of leptospirosis and rapid treatment with amoxycillin was the main treatment, probably contributing to this low fatality rate. PMID:26528546

    Background In the last few decades,there has been a delay in first-time pregnancies,and the average age of women at the time of delivery has increased in many countries.Advanced maternal age is associated with adverse pregnancy outcomes.This study aimed to determine the present trends and pregnancy outcomes related to maternal age in China.Methods Data were collected from 39 hospitals in mainland of China.All deliveries were performed after 28 completed weeks of gestation and between January 1 and December 31,2011.In total,110 450 of 112 441 cases were included in the study.All enrolled cases were divided into 6 age groups with 5-year intervals.The x2 test or Fisher's exact test and unadjusted binary-Logistic regression were used for statistical analysis.Results The mean age at the time of delivery was 28.18±4.70 years (range,14-52 years).The teenage group (15-19 years) had a higher risk than the 25-29-year old group for anemia (odds ratio (OR),1.4),preeclampsia (OR,1.6),preterm birth (OR,2.1),low birth weight neonates (OR,2.3),and perinatal mortality (OR,3.6).The 35-39-year old group and ≥40-year-old group had a higher risk than the 25-29-year-old group for leiomyoma (OR,4.2 vs.5.8),pregestational diabetes (OR,2.2 vs.3.8),chronic hypertension (OR,4.6 vs.6.5),gestational diabetes (OR,2.6 vs.3.5),preeclampsia (OR,2.5 vs.3.6),premature delivery (OR,1.8 vs.2.4),postpartum hemorrhage (OR,1.5 vs.1.7),placenta previa (OR,2.7 vs.4.0),placental abruption (OR,1.4 vs.2.5),cesarean delivery (OR,2.1 vs.2.5),macrosomia (OR,1.2 vs.1.2),low birth weight neonates (OR,1.6 vs.2.3),and perinatal mortality (OR,1.6 vs.3.7).Conclusion Maternal and neonatal risks are higher during the teenage years and at an advanced maternal age; 20-30 years of age is the lowest risk period for pregnancy and delivery.

  18. Estimating age conditional probability of developing disease from surveillance data

    2004-07-01

    Full Text Available Abstract Fay, Pfeiffer, Cronin, Le, and Feuer (Statistics in Medicine 2003; 22; 1837–1848 developed a formula to calculate the age-conditional probability of developing a disease for the first time (ACPDvD for a hypothetical cohort. The novelty of the formula of Fay et al (2003 is that one need not know the rates of first incidence of disease per person-years alive and disease-free, but may input the rates of first incidence per person-years alive only. Similarly the formula uses rates of death from disease and death from other causes per person-years alive. The rates per person-years alive are much easier to estimate than per person-years alive and disease-free. Fay et al (2003 used simple piecewise constant models for all three rate functions which have constant rates within each age group. In this paper, we detail a method for estimating rate functions which does not have jumps at the beginning of age groupings, and need not be constant within age groupings. We call this method the mid-age group joinpoint (MAJ model for the rates. The drawback of the MAJ model is that numerical integration must be used to estimate the resulting ACPDvD. To increase computational speed, we offer a piecewise approximation to the MAJ model, which we call the piecewise mid-age group joinpoint (PMAJ model. The PMAJ model for the rates input into the formula for ACPDvD described in Fay et al (2003 is the current method used in the freely available DevCan software made available by the National Cancer Institute.

    Full Text Available We investigated the impact of a moderate heatwave on a range of presenting morbidities in England. Asthma, difficulty breathing, cerebrovascular accident, and cardiovascular symptoms were analysed using general practitioner in hours (GPIH, out of hours (GPOOH and emergency department (ED syndromic surveillance systems. Data were stratified by age group and compared between a heatwave year (2013 and non-heatwave years (2012, 2014. Incidence rate ratios were calculated to estimate the differential impact of heatwave compared to non-heatwave summers: there were no apparent differences for the morbidities tested between the 2013 heatwave and non-heatwave years. A subset of GPIH data were used to study individuals at higher risk from heatwaves based on their pre-existing disease. Higher risk patients were not more likely to present at GPs or ED than other individuals. Comparing GPIH consultations and ED attendances for myocardial infarction/ischaemia (MI, there was evidence of a fall in the presentation of MI during the heatwave, which was particularly noted in the 65–74 years age group (and over 75 years in ED attendances. These results indicate the difficulty in identifying individuals at risk from non-fatal health effects of heatwaves and hot weather.

    The critically endangered red wolf (Canis rufus) has been subject to a strictly managed captive breeding program for three decades. A retrospective demographic analysis of the captive population was performed based on data from the red wolf studbook. Data analyses revealed a decrease in the effective population size relative to the total population size, and changes in age structure and inbreeding coefficients over time. To varying degrees, the probability of successful breeding and litter sizes declined in association with increasing dam age and sire inbreeding coefficients. Neonate survival also declined with increasing dam age. Recent changes in strategies regarding breed-pair recommendations have resulted in moderate increases in reproductive success. PMID:19504595

    2012-11-01

    Full Text Available Background: A growing body of evidence points to the emission of greenhouse gases from human activity as a key factor in climate change. This in turn affects human health and wellbeing through consequential changes in weather extremes. At present, little is known about the effects of weather on the health of sub-Saharan African populations, as well as the related anticipated effects of climate change partly due to scarcity of good quality data. We aimed to study the association between weather patterns and daily mortality in the Nouna Health and Demographic Surveillance System (HDSS area during 1999–2009. Methods: Meteorological data were obtained from a nearby weather station in the Nouna HDSS area and linked to mortality data on a daily basis. Time series Poisson regression models were established to estimate the association between the lags of weather and daily population-level mortality, adjusting for time trends. The analyses were stratified by age and sex to study differential population susceptibility. Results: We found profound associations between higher temperature and daily mortality in the Nouna HDSS, Burkina Faso. The short-term direct heat effect was particularly strong on the under-five child mortality rate. We also found independent coherent effects and strong associations between rainfall events and daily mortality, particularly in elderly populations. Conclusion: Mortality patterns in the Nouna HDSS appear to be closely related to weather conditions. Further investigation on cause-specific mortality, as well as on vulnerability and susceptibility is required. Studies on local adaptation and mitigation measures to avoid health impacts from weather and climate change is also needed to reduce negative effects from weather and climate change on population health in rural areas of the sub-Saharan Africa.

    Full Text Available Abstract Background Stage at diagnosis plays a significant role in colorectal cancer (CRC survival. Understanding which factors contribute to a more advanced stage at diagnosis is vital to improving overall survival. Comorbidity, race, and age are known to impact receipt of cancer therapy and survival, but the relationship of these factors to stage at diagnosis of CRC is less clear. The objective of this study is to investigate how comorbidity, race and age influence stage of CRC diagnosis. Methods Two distinct healthcare populations in the United States (US were retrospectively studied. Using the Cancer Care Outcomes Research and Surveillance Consortium database, we identified CRC patients treated at 15 Veterans Administration (VA hospitals from 2003–2007. We assessed metastatic CRC patients treated from 2003–2006 at 10 non-VA, fee-for-service (FFS practices. Stage at diagnosis was dichotomized (non-metastatic, metastatic. Race was dichotomized (white, non-white. Charlson comorbidity index and age at diagnosis were calculated. Associations between stage, comorbidity, race, and age were determined by logistic regression. Results 342 VA and 340 FFS patients were included.

    Climate change experts predict the number of nuisance-biting arthropods in England will increase but there is currently no known surveillance system in place to monitor or assess the public health impact of arthropod bites. This retrospective ecological study utilized arthropod bites requiring healthcare from five national real-time syndromic surveillance systems monitoring general practitioner (GP) consultations (in-hours and out-of-hours), emergency department (ED) attendances and telephone calls to remote advice services to determine baseline incidence in England between 2000 and 2013 and to assess the association between arthropod bites and temperature. During summer months (weeks 20-40) we estimated that arthropod bites contribute a weekly median of ~4000 GP consultations, 750 calls to remote advice services, 700 ED and 1300 GP out-of-hours attendances. In all systems, incidence was highest during summer months compared to the rest of the year. Arthropod bites were positively associated with temperature with incidence rate ratios (IRRs) that ranged between systems from 1·03 [95% confidence interval (CI) 1·01-1·06] to 1·14 (95% CI 1·11-1·16). Using syndromic surveillance systems we have established and described baseline incidence of arthropod bites and this can now be monitored routinely in real time to assess the impact of extreme weather events and climate change.

    During surveillance of the 9975 shipping package at the Savannah River Site K-Area Complex, several package dimensions are recorded. The analysis described in this report shows that, based on the current data analysis, two of these measurements, Upper Assembly Outer Diameter (UAOD) and Upper Assembly Inside Height (UAIH), do not have statistically significant aging trends regardless of wattage levels. In contrast, this analysis indicates that the measurement of Air Shield Gap (ASGap) does show a significant increase with age. It appears that the increase is greater for high wattage containers, but this result is dominated by two measurements from high-wattage containers. For all three indicators, additional high-wattage, older containers need to be examined before any definitive conclusions can be reached. In addition, the current analysis indicates that ASGap measurements for low and medium wattage containers are increasing slowly over time. To reduce uncertainties and better capture the aging trend for these containers, additional low and medium wattage older containers should also be examined. Based on this analysis, surveillance guidance is to augment surveillance containers resulting from 3013 surveillance with 9975-focused sampling that targets older, high wattage containers and also includes some older, low and medium wattage containers. This focused sampling began in 2015 and will continue in 2016. The UAOD, UAIH and ASGap data are highly variable. It is possible that additional factors such as seasonal variation and packaging site location might reduce variability and be useful for focusing surveillance and predicting aging.

    Thrombocytopenia is a common finding in small for gestational age (SGA) neonates and is thought to result from a unique pathophysiologic mechanism related to chronic intrauterine hypoxia. Our objective was to estimate the incidence and severity of early-onset thrombocytopenia in SGA neonates, and to identify risk factors for thrombocytopenia. We performed a retrospective cohort study of all consecutive SGA neonates admitted to our ward and a control group of appropriate for gestational age (AGA) neonates matched for gestational age at birth. Main outcome measures were incidence and severity of thrombocytopenia, hematological and clinical risk factors for thrombocytopenia, and bleeding. A total of 330 SGA and 330 AGA neonates were included, with a mean gestational age at birth of 32.9 ± 4 weeks. Thrombocytopenia (<150x109/L) was found in 53% (176/329) of SGA neonates and 20% (66/330) of AGA neonates (relative risk (RR) 2.7, 95% confidence interval (CI) [2.1, 3.4]). Severe thrombocytopenia (21-50x109/L) occurred in 25 neonates (8%) in the SGA and 2 neonates (1%) in the AGA group (RR 12.5, 95% CI [3.0, 52.5]). Platelet counts <20x109/L were not recorded. Within the SGA group, lower gestational age at birth (p = <0.01) and erythroblastosis (p<0.01) were independently associated with a decrease in platelet count. Platelet count was positively correlated with birth weight centiles. In conclusion, early-onset thrombocytopenia is present in over 50% of SGA neonates and occurs 2.7 times as often as in AGA neonates. Thrombocytopenia is seldom severe and is independently associated with lower gestational age at birth and erythroblastosis. PMID:27177157

    Full Text Available Cystic echinococcosis (CE and bovine cysticercosis (BC are two important parasitic zoonoses, whose prevalence varies among European countries. Few data are available on prevalence and geographic distribution of these two diseases in Veneto region in north-eastern Italy, where they are generally perceived as minor public health problems. Available data from regional farms on cattle positive to CE and BC and slaughtered in the period 2006-2010 were analysed by spatial scan statistic using a Bernoulli probability model. Out of 576 bovines testing positive to CE, 467 were found to be autochthonous cases. Three significant CE clusters were identified, the most likely one (P <0.001 located in the eastern part of the Veneto region. As for BC, two clusters were identified from 148 animals testing positive, 91 of which were autochthonous. An epidemiological survey was conducted and the most likely CE cluster was centred, collecting faecal samples from 28 dogs living in the farms of the area. Out of five animals (all shepherd dogs found positive for taenid eggs by copromicroscopy, one was confirmed positive for Echinococcus granulosus by means of polymerase chain reaction. The study demonstrates the usefulness of integration of slaughterhouse data and geographical coordinates of farms involved for effective surveillance of CE and BC. The reliability of the spatial analysis in the identification of clusters of EC cases was confirmed by the finding of one dog positive for E. granulosus.

    Full Text Available Abstract Background The purposes of this study are to document psychosocial stressors and medical conditions associated with development of insomnia in school-age children and to report use of hypnosis for this condition. Methods A retrospective chart review was performed for 84 children and adolescents with insomnia, excluding those with central or obstructive sleep apnea. All patients were offered and accepted instruction in self-hypnosis for treatment of insomnia, and for other symptoms if it was felt that these were amenable to therapy with hypnosis. Seventy-five patients returned for follow-up after the first hypnosis session. Their mean age was 12 years (range, 7–17. When insomnia did not resolve after the first instruction session, patients were offered the opportunity to use hypnosis to gain insight into the cause. Results Younger children were more likely to report that the insomnia was related to fears. Two or fewer hypnosis sessions were provided to 68% of the patients. Of the 70 patients reporting a delay in sleep onset of more than 30 minutes, 90% reported a reduction in sleep onset time following hypnosis. Of the 21 patients reporting nighttime awakenings more than once a week, 52% reported resolution of the awakenings and 38% reported improvement. Somatic complaints amenable to hypnosis were reported by 41%, including chest pain, dyspnea, functional abdominal pain, habit cough, headaches, and vocal cord dysfunction. Among these patients, 87% reported improvement or resolution of the somatic complaints following hypnosis. Conclusion Use of hypnosis appears to facilitate efficient therapy for insomnia in school-age children.

    Data on the elderly are rarely collected in humanitarian emergencies. During a refugee crisis in South Sudan, Médecins Sans Frontières developed a prospective mortality surveillance system collecting data for those aged ≥50 years and found that the elderly were dying at five times the rate of those aged 5-49 years. Practical and ethical issues arose. Were reported ages accurate? Since no baseline exists, what does the mortality rate mean? Should programmatic changes be made without evidence that these would reduce the elderly mortality rate? We outline issues to be addressed to enable informed decisions on response to elderly populations in emergency settings. PMID:24114674

    Full Text Available BACKGROUND: The importance of understanding age when estimating the impact of influenza on hospitalizations and deaths has been well described, yet existing surveillance systems have not made adequate use of age-specific data. Monitoring influenza-related morbidity using electronic health data may provide timely and detailed insight into the age-specific course, impact and epidemiology of seasonal drift and reassortment epidemic viruses. The purpose of this study was to evaluate the use of emergency department (ED chief complaint data for measuring influenza-attributable morbidity by age and by predominant circulating virus. METHODS AND FINDINGS: We analyzed electronically reported ED fever and respiratory chief complaint and viral surveillance data in New York City (NYC during the 2001-2002 through 2005-2006 influenza seasons, and inferred dominant circulating viruses from national surveillance reports. We estimated influenza-attributable impact as observed visits in excess of a model-predicted baseline during influenza periods, and epidemic timing by threshold and cross correlation. We found excess fever and respiratory ED visits occurred predominantly among school-aged children (8.5 excess ED visits per 1,000 children aged 5-17 y with little or no impact on adults during the early-2002 B/Victoria-lineage epidemic; increased fever and respiratory ED visits among children younger than 5 y during respiratory syncytial virus-predominant periods preceding epidemic influenza; and excess ED visits across all ages during the 2003-2004 (9.2 excess visits per 1,000 population and 2004-2005 (5.2 excess visits per 1,000 population A/H3N2 Fujian-lineage epidemics, with the relative impact shifted within and between seasons from younger to older ages. During each influenza epidemic period in the study, ED visits were increased among school-aged children, and each epidemic peaked among school-aged children before other impacted age groups.

    New surveillance technologies like those included in ambient assisted living - such as body-worn and passive environmental sensors, smart interfaces, and communications networks - are being developed to improve the security and safety of "at risk" older people, but ethical questions have been raised about the extent to which they compromise the rights and privacy of the people being monitored. The qualitative study we conducted was designed to help us understand the ways these novel surveillance technologies would influence individuals' everyday experiences of home. Participants felt new forms of surveillance would influence their sense of security, autonomy, and self-confidence, and would alter perceptions of home. The findings emphasize the need to improve our understanding of how ambient assisted living will affect the lives of those being monitored. PMID:26742899

Postmarketing and claims data were analyzed to determine the risk of malignancy in MS patients treated with intramuscular IFNβ-1a.Materials and methods: The cumulative reporting rates of suspected adverse drug reactions coded to malignancy in the intramuscular IFNβ-1a global safety database were compared with malignancy incidence rates in the World Health Organization GLOBOCAN database. In addition, using data from a large US claims database, the cumulative prevalence of malignancy in MS patients treated with intramuscular IFNβ-1a was compared with non-MS population controls, MS patients without intramuscular IFNβ-1a use, and untreated MS patients. Mean follow-up was approximately 3 years for all groups, ie, 3.1 years for the intramuscular IFNβ-1a group (range 0.02–6.0 years, 2.6 years for non-MS population controls (range 0–6.0 years, 2.6 years for the intramuscular IFNβ-1a nonuse group (range 0.01–6.0 years, and 2.4 years for the untreated MS group (range 0.01–6.0 years.Results: An estimated 402,250 patients received intramuscular IFNβ-1a during the postmarketing period. Cumulative reporting rates of malignancy in this population were consistent with GLOBOCAN incidence rates observed within the general population. The claims database included 12,894 MS patients who received intramuscular IFNβ-1a. No significant difference in malignancy prevalence was observed in intramuscular IFNβ-1a users compared with other groups.Conclusion: Results from this evaluation provide no evidence of an increased risk of

    1998-04-01

    Attention to the 4 poliomyelitis surveillance indicators approved by the International Commission for the Certification of Poliomyelitis Eradication (ICCPE) in 1994, has deteriorated since the Americas were declared free from wild poliovirus. The indicators are designed to measure the performance of health services and the sensitivity of the surveillance system to detect wild poliovirus circulating in the community. Sensitivity is the most important characteristic of the poliomyelitis surveillance system and it is measured by the rate of acute flaccid paralysis (AFP) per 100,000 under age 15 years. As of March 21, 1998, the AFP rate reached its lowest level yet in the Americas, with only Bolivia, Chile, and Honduras presenting an acceptable rate (the analysis does not include the US and Canada). The other countries in the Caribbean region and Latin America had rates under 1 AFP case per 100,000 children under age 15. It follows that only 6% of children under age 15 in the region are currently protected by a sensitive AFP surveillance system. Poliovirus may therefore be circulating silently in the region. Renewed attention must be given to the AFP surveillance indicators. PMID:12321498

    Full Text Available BACKGROUND: To prevent and control infectious diseases, it is important to understand how sex and age influence morbidity rates, but consistent clear descriptions of differences in the reported incidence of infectious diseases in terms of sex and age are sparse. METHODS AND FINDINGS: Data from the Japanese surveillance system for infectious diseases from 2000 to 2009 were used in the analysis of seven viral and four bacterial infectious diseases with relatively large impact on the Japanese community. The male-to-female morbidity (MFM ratios in different age groups were estimated to compare incidence rates of symptomatic reported infection between the sexes at different ages. MFM ratios were >1 for five viral infections out of seven in childhood, i.e. male children were more frequently reported as infected than females with pharyngoconjunctival fever, herpangina, hand-foot-and-mouth disease, mumps, and varicella. More males were also reported to be infected with erythema infectiosum and exanthema subitum, but only in children 1 year of age. By contrast, in adulthood the MFM ratios decreased to <1 for all of the viral infections above except varicella, i.e. adult women were more frequently reported to be infected than men. Sex- and age-related differences in reported morbidity were also documented for bacterial infections. Reported morbidity for enterohemorrhagic Escherichia coli infection was higher in adult females and females were reportedly more infected with mycoplasma pneumonia than males in all age groups up to 70 years. CONCLUSIONS: Sex-related differences in reported morbidity for viral and bacterial infections were documented among different age groups. Changes in MFM ratios with age may reflect differences between the sexes in underlying development processes, including those affecting the immune, endocrine, and reproductive systems, or differences in reporting rates.

The aim of this study is to explore patterns of adult (15–64 years mortality in an Ethiopian population over time, by gender, urban or rural lifestyle, causes of death and in relation to household economic status and decision-making. Methods The study was conducted in Butajira Demographic Surveillance Site (DSS in south-central Ethiopia among adults 15–64 years old. Cohort analysis of surveillance data was conducted for the years 1987–2004 complemented by a prospective case-referent (case control study over two years. Rate ratios were computed to assess the relationships between mortality and background variables using a Poisson regression model. In the case-referent component, odds ratios (95% confidence intervals were used to assess the effect of certain risk factors that were not included in the surveillance system. Results A total of 367 940 person years were observed in a period of 18 years, in which 2 860 deaths occurred. One hundred sixty two cases and 486 matched for age, sex and place of residence controls were included in the case referent (case control study. Only a modest downward trend in adult mortality was seen over the 18 year period. Rural lifestyle carried a significant survival disadvantage [mortality rate ratio 1.62 (95% CI 1.44 to 1.82, adjusted for gender, period and age group], while the overall effects of gender were negligible. Communicable disease mortality was appreciably higher in rural areas [rate ratio 2.05 (95% CI 1.73 to 2.44, adjusted for gender, age group and period]. Higher mortality was associated with a lack of literacy in a household, poor economic status and lack of women's decision making. Conclusion A complex pattern of adult mortality prevails, still influenced by war, famine and communicable diseases. Individual factors such as a lack of education, low economic

  10. The effect of age in breast conserving therapy: A retrospective analysis on pathology and clinical outcome data

    International Nuclear Information System (INIS)

    Background and propose: Age is an important prognostic marker of patient outcome after breast conserving therapy; however, it is not clear how age affects the outcome. This study aimed to explore the relationship between age with the cell quantity and the radiosensitivity of microscopic disease (MSD) in relation to treatment outcome. Materials and methods: We employed a treatment simulation framework which contains mathematic models for describing the load and spread of MSD based on a retrospective cohort of breast pathology specimens, a surgery simulation model for estimating the remaining MSD quantity and a tumor control probability model for predicting the risk of local recurrence following radiotherapy. Results: The average MSD cell quantities around the primary tumor in younger (age ⩽ 50 years) and older patients were estimated at 1.9 ∗ 108 cells and 8.4 ∗ 107 cells, respectively (P < 0.01). Following surgical simulation, these numbers decreased to 2.0 ∗ 107 cells and 1.3 ∗ 107 cells (P < 0.01). Younger patients had smaller average surgical resection volume (118.9 cm3) than older patients (162.9 cm3, P < 0.01) but larger estimated radiosensitivity of MSD cells (0.111 Gy−1 versus 0.071 Gy−1, P < 0.01). Conclusion: The higher local recurrence rate in younger patients could be explained by larger clonogenic microscopic disease cell quantity, even though the microscopic disease cells were found to be more radiosensitive

    In Senegal, due to the young age of the population (60%) the concerns of the old tend to be put in the background. And yet, problems related to old age are a reality. These problems come up not in terms of demography (the old represent only 4.7% of the population), but in terms of the breaking-up of the social fabric, urbanization and the dismantling of the solidarity and poverty networks. This work is based on a collection of qualitative data from three studies conducted between 2008 and 2011 with the elderly to assess their real- life experiences, their perception of aging, their challenges and coping strategies. The results showed a transformation in the role and status of the old; this transformation being caused by social and society-related mutations. As a result, the inter-generation solidarity links have much loosened in the urban areas making the old people more vulnerable (in economic, social, health terms), especially those in charge of a family. The situation has been made worse by the unemployment affecting their offspring. In addition, the old people, who are often suffering from chronic diseases, find it hard to take charge of their medical expenses, despite the institution of the National Sesame Health Plan for the old or free health care policy. This has made them even more vulnerable. Yet before this precarious situation, the elderly develop strategies to cope with difficulties. Some recommendations have been made with a view to improving their lives and socioeconomic condition. PMID:26852947

    Full Text Available BACKGROUND: Epstein-Barr Virus (EBV is a globally prevalent herpesvirus associated with infectious mononucleosis and many malignancies. The survey on EBV prevalence appears to be important to study EBV-related diseases and determine when to administer prophylactic vaccine. The purpose of this retrospective study was to collect baseline information about the prevalence of EBV infection in Chinese children. METHODOLOGY/PRINCIPAL FINDING: We collected 1778 serum samples from healthy children aged 0 to 10, who were enrolled in conventional health and nutrition examinations without any EBV-related symptom in 2012 and 2013 in North China (n = 973 and South China (n = 805. We detected four EBV-specific antibodies, i.e., anti-VCA-IgG and IgM, anti-EBNA-IgG and anti-EA-IgG, by ELISA, representing all of the phases of EBV infection. The overall EBV seroprevalence in samples from North and South China were 80.78% and 79.38% respectively. The EBV seropositivity rates dropped slightly at age 2, and then increased gradually with age. The seroprevalence became stabilized at over 90% after age 8. In this study, the seroprevalence trends between North and South China showed no difference (P>0.05, and the trends of average antibody concentrations were similar as well (P>0.05. CONCLUSIONS/SIGNIFICANCE: EBV seroprevalence became more than 50% before age 3 in Chinese children, and exceed 90% after age 8. This study can be helpful to study the relationship between EBV and EBV-associated diseases, and supportive to EBV vaccine development and implementation.

    Full Text Available Abstract Background The malaria test positivity rate (TPR is increasingly used as an indicator of malaria morbidity because TPR is based on laboratory-confirmed cases and is simple to incorporate into existing surveillance systems. However, temporal trends in TPR may reflect changes in factors associated with malaria rather than true changes in malaria morbidity. This study examines the effects of age, area of residence and diagnostic test on TPR at two health facilities in regions of Uganda with differing malaria endemicity. Methods The analysis included data from diagnostic blood smears performed at health facilities in Walukuba and Aduku between January 2009 and December 2010. The associations between age and time and between age and TPR were evaluated independently to determine the potential for age to confound temporal trends in TPR. Subsequently, differences between observed TPR and TPR adjusted for age were compared to determine if confounding was present. A similar analysis was performed for area of residence. Temporal trends in observed TPR were compared to trends in TPR expected using rapid diagnostic tests, which were modelled based upon sensitivity and specificity in prior studies. Results Age was independently associated with both TPR and time at both sites. At Aduku, age-adjusted TPR increased relative to observed TPR due to the association between younger age and TPR and the gradual increase in age distribution. At Walukuba, there were no clear differences between observed and age-adjusted TPR. Area of residence was independently associated with both TPR and time at both sites, though there were no clear differences in temporal trends in area of residence-adjusted TPR and observed TPR at either site. Expected TPR with pLDH- and HRP-2-based rapid diagnostic tests (RDTs was higher than observed TPR at all time points at both sites. Conclusions Adjusting for potential confounders such as age and area of residence can ensure that

  14. Surveillance test and monitoring strategy for the availability improvement of standby equipment using age-dependent model

    International Nuclear Information System (INIS)

    In many cases, the safety of a nuclear power plant greatly depends on the successful operation of specific standby equipment at the time of demand arrival. For the effective management of safety-critical standby equipment, unavailability measures are introduced and widely applied. In this study, we propose an age-dependent unavailability model for standby equipment that considers aging-relevant information, such as the number of actual operations, the elapsed time from installation, and maintenance activities, in an integrated manner. Based on the proposed model, we present two availability enhancement strategies: the Online Monitoring based Inspection Method (OMIM) and the Shortening Surveillance Test Interval Method (SSTIM). In the OMIM, ‘elapsed-time sensitive' elements are monitored, without actual operation, at the differentiated monitoring interval with the help of sensing devices. For the remaining parts of the elements, actual testing is performed with an adaptive interval for each standby turn by the SSTIM. The effectiveness of the proposed enhancement schemes is demonstrated through a case study for the motor-operated valve (MOV). It is our belief that the proposed schemes can be widely applied in areas such as equipment testing, maintenance strategies, dynamic probabilistic safety assessment (PSA), and risk-informed regulations. - Highlights: • An age-dependent unavailability model for standby equipment was investigated. • An Online Monitoring-based Inspection Method was suggested. • Changing the test interval for each standby turn was suggested. • The effectiveness of the suggested methods was analyzed quantitatively

    Full Text Available Background. Delirium is a common and devastating condition which has been well characterized in elderly cancer patients, but little is known about delirium in cancer patients under the age of 65. Aim. A pilot study to explore the incidence and potential causes of delirium in hospitalized advanced cancer patients at the age of 18–56 years. Design. A retrospective chart review using validated instruments was used to examine the charts of hematology-oncology admissions in a large academic institution. Data was collected as to the likelihood of delirium and potential precipitants. Results. Delirium incidence was 29% among advanced cancer patients. The associated precipitants of delirium were multifactorial, the most common being medications and infection. Delirium was more common in patients admitted for either acute symptom management or the presence of a lung malignancy. Patients with delirium demonstrated significantly increased total hospital cost and a borderline significant result for increased mortality compared to those without delirium. Conclusions. Delirium is common in hospitalized advanced cancer patients (age 18–56 years and the cause is typically multifactorial. Delirium results in a more complicated hospital course and likely increased mortality. Further research is needed to define strategies to prevent and treat this common and distressing condition.

    Objective To understand the disease burden due to Herpes Zoster (HZ) among people aged ≥50 years old in China and provide baseline data for future similar studies, and provide evidence for development of herpes zoster vaccination strategy. Methods Retrospective cohort study was conducted in 4 townships and one community. A questionnaire was used to collect information on incidence and cost of HZ among people aged ≥ 50 years old. Results The cumulative incidence rate was 22.6/1,000 among people aged ≥ 50 years old. The average annual incidence rate of HZ was 3.43/1,000 among people aged ≥ 50 years old in 2010–2012. Cumulative incidence and average annual incidence rate increased with age: the cumulative incidence of HZ among people aged ≥ 80 years old was 3.34 times of that among 50- years old (52.3/1000vs15.7/1,000); average annual incidence rate rises from 2.66/1,000 among 50- years old to 8.55/1,000 among 80- year old. Cumulative incidence and average annual incidence rate for females were higher than that for males (cumulative incidence, 26.5/1000vs18.7/1,000; annual incidence rate, 3.95/1000vs2.89/1,000). Cumulative incidence and average annual incidence rate in urban were higher than in rural (cumulative incidence, 39.5/1000vs 17.2/1,000; annual incidence rate, 7.65/1000vs2.06/1,000). The hospitalization rate of HZ was 4.53%. And with the increase of age, the rate has an increasing trend. HZ costs 945,709.5 RMB in total, corresponding to 840.6 RMB per patient with a median cost of 385 RMB (interquartile range 171.7–795.6). Factors associated with cost included the first onset year, area, whether hospitalized and whether sequelae left. Conclusion Incidence rate, complications, hospitalization rate and average cost of HZ increase with age. We recommend that the HZ vaccinations should target people aged ≥50 years old if Zoster vaccine is licensed in China. PMID:27055179

    Objectives To test the association of age (adolescents vs. older women) and place of delivery with receipt of immediate postpartum contraception in Mexico. Study design Retrospective cohort study, Mexico, nationally representative sample of women 12–39 years old at last delivery. We used multivariable logistic regression to test the association of self-reported receipt of postpartum contraception prior to discharge with age and place of delivery (public, employment based, private, or out of facility). We included individual and household-level confounders and calculated relative and absolute multivariable estimates of association. Results Our analytic sample included 7022 women (population, N = 9,881,470). Twenty percent of the population was 12–19 years old at last birth, 55% aged 20–29 and 25% 30–39 years old. Overall, 43% of women reported no postpartum contraceptive method. Age was not significantly associated with receipt of a method, controlling for covariates. Women delivering in public facilities had lower odds of receipt of a method (Odds Ratio = 0.52; 95% Confidence Interval (CI) = 0.40–0.68) compared with employment-based insurance facilities. We estimated 76% (95% CI = 74–78%) of adolescents (12–19 years) who deliver in employment-based insurance facilities leave with a method compared with 59% (95% CI = 56–62%) who deliver in public facilities. Conclusion Both adolescents and women ages 20–39 receive postpartum contraception, but nearly half of all women receive no method. Place of delivery is correlated with receipt of postpartum contraception, with lower rates in the public sector. Lessons learned from Mexico are relevant to other countries seeking to improve adolescent health through reducing unintended pregnancy. Implications Adolescents receive postpartum contraception as often as older women in Mexico, but half of all women receive no method. PMID:26828625

    Myelodysplastic syndromes (MDS) is a disease of predominantly elderly patients with a median age of >70 yrs. However, data on the management of these patients outside of clinical trials are scarce. To assess patterns of MDS management in routine patient care with regard to the impact of age, we conducted a multicenter, representative survey of MDS health services in Germany. Data of 269 patients treated at 57 institutions were collected from preplanned chart reviews and were analyzed retrospectively. At diagnosis, median age was 70 yrs, 50% of patients had a Karnofsky index (KI) of 90%, and 12% had a comorbidity index ≥ 3 according to Sorror et al. (J Clin Oncol, 25, 2007, 4246). Cytogenetic analysis and International Prognostic Scoring System (IPSS) risk assessment were performed significantly less frequently in patients >75 yrs than in patients ≤ 75 yrs (P 75 yrs (51% vs. 37%, P = 0.007). In bivariate analysis age ≤ 75 yrs (y/n, P = 0.007) was a significant predictor for active treatment with no correlation with the other predictors [IPSS risk score int-2 or high (y/n, P = 0.005), WHO subtypes RCUD (y/n, P < 0.001), RCMD (y/n, P = 0.003), RAEB II (y/n, P < 0.001), or CMML I (y/n, P = 0.020)]. This survey confirms the impact of age on the thoroughness of MDS diagnosis and the decision for active treatment. As cytogenetic analysis and risk assessment are essential for the choice of appropriate therapy, elderly patients in particular may not be receiving adequate treatment. PMID:24102637

    Full Text Available Abstract Background A new vaccine against Rotavirus (RV gastroenteritis was introduced in Germany in 2006. In 1997 the first RV vaccine was withdrawn due to an increased incidence in intussusception (IS. Thus, an accurate estimation of the incidence of IS is important for post-licensure surveillance. Methods IS-Data were obtained from the 'Erhebungseinheit für seltene pädiatrische Erkrankungen Deutschland' (ESPED, German surveillance unit for rare pediatric diseases collaborations' central register where all cases of intussusception in Germany for the years 2006 and 2007 are collected (n = 1200. In order to obtain an unbiased estimate of the incidence, it is necessary to determine the population under risk out of which these cases originated, and the proportion of real cases not reported to the registry (underreporting. In order to assess underreporting, a random sample of 31 hospitals was re-assessed by an outside reviewer. The estimation of incidence was done using a single Maximum-Likelihood (ML estimator based on data from both the registry and the sample. Results The uncorrected observed incidence was calculated to be 26.6/100,000 child-years for children below 1 year old, 23.8 for those below 2 years old, and 5.2 for those below 15 years old. The review revealed a mean reporting quota of about 41% and the ML approach yielded an incidence of 51.5/100,000 child-years (95%CI [41.7;61.1] for children below 2 years of age. Conclusions While substantial under-reporting led to very conservative estimates of the IS incidence, the approach described here allows an accurate estimation of IS incidence including corresponding confidence bands. Therefore, ML estimation is a straightforward instrument to derive stable, unbiased estimates in epidemiological studies with incomplete data.

    Full Text Available The objective of the Food and Nutrition Surveillance System (SISVAN is to monitor the food intake of individuals attended by the Brazilian Unified Health System (SUS. The objective of this research was to identify the feeding practices of children under 24 months of age who were attended at Primary Healthcare Units (UBS, using SISVAN, and to assess the relationship with maternal sociodemographic profiles. A cross-sectional study was conducted in order to evaluate 350 children using the Food Consumption Marker Form of SISVAN, and maternal demographic data to identify sociodemographic profiles by exploratory factor analysis. Of the children assessed, 41.1% were under 6 months of age and 98.7% of those between 6 and 23 months had an inadequate intake. Two sociodemographic profiles were found: Profile 1 (mothers with lower income, less education, and recipients of the 'Bolsa Família' conditional family grant program associated with the consumption of water/tea, cow's milk and salty baby food; and Profile 2 (older mothers with many children and with a larger number of residents in the household associated with breast milk consumption (p = 0.048. The use of SISVAN made it possible to identify that children had inadequate feeding practices, and Profile 1 appears to be a risk profile for weaning.

    To assess the adequacy of a vegetarian diet at old age, the dietary intake (assessed through dietary history with cross-check) of 44 apparently healthy lacto-(ovo-)vegetarians, aged 65-97 years, was evaluated. Adequacy was assessed by a comparison of nutrient intake with (Dutch) recommendations and by evaluating data on nutritional status. The results were also compared with data of elderly omnivores. In contrast to elderly omnivores, percentages of energy from protein (13%), fat (37%), and carbohydrates (50%) as well as P/S ratio (0.63) were close to or within the range of Dutch guidelines regarding a healthy diet (percentages of energy from protein, fat, and carbohydrates 10-15, 30-35, and 55%, respectively: P/S ratio 0.5-1.0). For most of the micronutrients studied intake was adequate, and nutrient density of the vegetarian diet was higher than of the omnivorous diet. However, the supply of zinc (average daily intake 8.5 and 7.6 mg for men and women, respectively), iron (because of lower bioavailability of nonheme iron), vitamin B12 (women only: intake 2.3 micrograms/day), and water (daily intake less than 1600 ml for 30% of the vegetarians) need special attention, considering the relatively high prevalence of a marginal status of these nutrients. In conclusion, a lacto-(ovo-)vegetarian diet can be adequate at old age, provided that it is carefully planned, especially with respect to the supply of iron, zinc, and vitamin B12. PMID:2212385

    Full Text Available Abstract Background In-vitro fertilization (IVF with blastocyst as opposed to cleavage stage embryos has been advocated to improve success rates. Limited information exists on which to predict which patients undergoing blastocyst embryo transfer (BET will achieve pregnancy. This study's objective was to evaluate the predictive value of patient and cycle characteristics for clinical pregnancy following fresh BET. Methods This was a retrospective cohort study from 2003–2007 at an academic assisted reproductive program. 114 women with infertility underwent fresh IVF with embryo transfer. We studied patients undergoing transfer of embryos at the blastocyst stage of development. Our main outcome of interest was clinical pregnancy. Clinical pregnancy and its associations with patient characteristics (age, body mass index, FSH, ethnicity and cycle parameters (thickness of endometrial stripe, number eggs, available cleaving embryos, number blastocysts available, transferred, and cryopreserved, and embryo quality were examined using Student's T test and Mann-Whitney-U tests as appropriate. Multivariable logistic regression models were created to determine independent predictors of CP following BET. Receiver Operating Characteristic analyses were used to determine the optimal thickness of endometrial stripe for predicting clinical pregnancy. Results Patients achieving clinical pregnancy demonstrated a thicker endometrial stripe and were younger preceding embryo transfer. On multivariable logistic regression analyses, Caucasian ethnicity (OR 2.641, 95% CI 1.054–6.617, thickness of endometrial stripe, (OR 1.185, 95% CI 1.006–1.396 and age (OR 0.879, 95% CI 0.789–0.980 predicted clinical pregnancy. By receiver operating characteristic analysis, endometrial stripe ≥ 9.4 mm demonstrated a sensitivity of 83% for predicting clinical pregnancy following BET. Conclusion In a cohort of patients undergoing fresh BET, thicker endometrial stripe, Caucasian

    Shelly Bolotin

    Full Text Available BACKGROUND: The World Health Organization and European Centre for Disease Prevention and Control have highlighted the importance of establishing systems to monitor severe influenza. Following the H1N1 (2009 influenza pandemic, a sentinel network of 23 Trusts, the UK Severe Influenza Surveillance System (USISS, was established to monitor hospitalisations due to confirmed seasonal influenza in England. This article presents the results of the first season of operation of USISS in 2010/11. METHODOLOGY/PRINCIPAL FINDINGS: A case was defined as a person hospitalised with confirmed influenza of any type. Weekly aggregate numbers of hospitalised influenza cases, broken down by flu type and level of care, were submitted by participating Trusts. Cases in 2010/11 were compared to cases during the 2009 pandemic in hospitals with available surveillance data for both time periods (n = 19. An unexpected resurgence in seasonal A/H1N1 (2009 influenza activity in England was observed in December 2010 with reports of severe disease. Reported cases over the period of 4 October 2010 to 13 February 2011 were mostly due to influenza A/H1N1 (2009. One thousand and seventy-one cases of influenza A/H1N1 (2009 occurred over this period compared to 409 at the same Trusts over the 2009/10 pandemic period (1 April 2009 to 6 January 2010. Median age of influenza A/H1N1 (2009 cases in 2010/11 was 35 years, compared with 20 years during the pandemic (p = <0.0001. CONCLUSIONS/SIGNIFICANCE: The Health Protection Agency successfully established a sentinel surveillance system for severe influenza in 2010/11, detecting a rise in influenza cases mirroring other surveillance indicators. The data indicate an upward shift in the age-distribution of influenza A/H1N1 (2009 during the 2010/11 influenza season as compared to the 2009/10 pandemic. Systems to enable the ongoing surveillance of severe influenza will be a key component in understanding and responding to the evolving

  8. Development and application of a living probabilistic safety assessment tool: Multi-objective multi-dimensional optimization of surveillance requirements in NPPs considering their ageing

    International Nuclear Information System (INIS)

    The benefits of utilizing the probabilistic safety assessment towards improvement of nuclear power plant safety are presented in this paper. Namely, a nuclear power plant risk reduction can be achieved by risk-informed optimization of the deterministically-determined surveillance requirements. A living probabilistic safety assessment tool for time-dependent risk analysis on component, system and plant level is developed. The study herein focuses on the application of this living probabilistic safety assessment tool as a computer platform for multi-objective multi-dimensional optimization of the surveillance requirements of selected safety equipment seen from the aspect of the risk-informed reasoning. The living probabilistic safety assessment tool is based on a newly developed model for calculating time-dependent unavailability of ageing safety equipment within nuclear power plants. By coupling the time-dependent unavailability model with a commercial software used for probabilistic safety assessment modelling on plant level, the frames of the new platform i.e. the living probabilistic safety assessment tool are established. In such way, the time-dependent core damage frequency is obtained and is further on utilized as first objective function within a multi-objective multi-dimensional optimization case study presented within this paper. The test and maintenance costs are designated as the second and the incurred dose due to performing the test and maintenance activities as the third objective function. The obtained results underline, in general, the usefulness and importance of a living probabilistic safety assessment, seen as a dynamic probabilistic safety assessment tool opposing the conventional, time-averaged unavailability-based, probabilistic safety assessment. The results of the optimization, in particular, indicate that test intervals derived as optimal differ from the deterministically-determined ones defined within the existing technical specifications

    Knowledge of bone age in achondroplasia is required for the prediction of adult height, timings of limb lengthening, and epiphysiodesis procedures. The purpose of this investigation was to determine the differences in skeletal age in achondroplasia and a control population with the Tanner-Whitehouse 3 method using the RUS score and to determine the right age for the interventional procedure for limb lengthening procedure or deformity correction in these patients. Left hand radiographs of 34 patients (age range, 5-18 years) with achondroplasia were evaluated for skeletal age using the RUS scoring system, which were compared with the left hand radiographs of 41 patients (age range, 5-18 years) without achondroplasia measuring skeletal age. The difference in chronological age and RUS bone age were evaluated statistically according to gender and age group. In the achondroplasia group, chronological age were 10.5±4.3 years for males and 10.1±3.6 years for females and RUS bone age were 9.2±4.0 years for males and 8.9±3.4 years for females, which showed statistically significantly difference (males p=0.0003 and females p 10 years in the study group, while 0.1±1.1 for 10 years in the control group, which also showed >statistically significant difference (10 years p10 years in achondroplasia patients compared to nonachondroplasia patients. We recommend the use of the Tanner-Whitehouse 3 method especially the radius, ulna, short bone score to measure the skeletal age and to wait for a longer time before interventional procedures in achondroplasia patients.

    As NASA transitions from the Space Shuttle era into the next phase of space exploration, the need to ensure the capture, analysis, and application of its research and medical data is of greater urgency than at any other previous time. In this era of limited resources and challenging schedules, the Human Research Program (HRP) based at NASA s Johnson Space Center (JSC) recognizes the need to extract the greatest possible amount of information from the data already captured, as well as focus current and future research funding on addressing the HRP goal to provide human health and performance countermeasures, knowledge, technologies, and tools to enable safe, reliable, and productive human space exploration. To this end, the Science Management Office and the Medical Informatics and Health Care Systems Branch within the HRP and the Space Medicine Division have been working to make both research data and clinical data more accessible to the user community. The Life Sciences Data Archive (LSDA), the research repository housing data and information regarding the physiologic effects of microgravity, and the Lifetime Surveillance of Astronaut Health Repository (LSAH-R), the clinical repository housing astronaut data, have joined forces to achieve this goal. The task of both repositories is to acquire, preserve, and distribute data and information both within the NASA community and to the science community at large. This is accomplished via the LSDA s public website (http://lsda.jsc.nasa.gov), which allows access to experiment descriptions including hardware, datasets, key personnel, mission descriptions and a mechanism for researchers to request additional data, research and clinical, that is not accessible from the public website. This will result in making the work of NASA and its partners available to the wider sciences community, both domestic and international. The desired outcome is the use of these data for knowledge discovery, retrospective analysis, and planning

    PurposeIntegral to maintaining good outcomes post-endovascular aneurysm repair (EVAR) is a robust surveillance protocol. A significant proportion of patients fail to comply with surveillance, exposing themselves to complications. We examine EVAR surveillance in Wessex (UK), exploring factors that may predict poor compliance.MethodsRetrospective analysis of 179 consecutive elective EVAR cases [2008–2013] was performed. 167 patients were male, with the age range of 50–95. Surveillance was conducted centrally (tertiary referral trauma centre) and at four spoke units. Surveillance compliance and predictors of non-compliance including age, gender, co-morbid status, residential location and socioeconomic status were analysed for univariate significance.ResultsFifty patients (27.9 %) were non-compliant with surveillance; 14 (8.1 %) had no imaging post-EVAR. At 1 year, 56.1 % (of 123 patients) were compliant. At years 2 and 3, 41.5 and 41.2 % (of 65 and 34 patients, respectively) were compliant. Four years post-EVAR, only one of eight attended surveillance (12.5 %). There were no statistically significant differences in age (p = 0.77), co-morbid status or gender (p = 0.64). Distance to central unit (p = 0.67) and surveillance site (p = 0.56) was non-significant. While there was a trend towards compliance in upper-middle-class socioeconomic groups (ABC1 vs. C1C2D), correlating with >50 % of non-compliant patients living within <10 mile radius of the central unit, overall predictive value was not significant (p = 0.82).ConclusionsCompliance with surveillance post-EVAR is poor. No independent predictor of non-compliance has been confirmed, but socioeconomic status appears to be relevant. There is a worrying drop-off in attendance beyond the first year. This study highlights a problem that needs to be addressed urgently, if we are to maintain good outcomes post-EVAR.

    Background Falls are the most frequently reported adverse events in inpatient settings. We conducted a retrospective case-control study of inpatient falls within aged care wards in a tertiary hospital to investigate the associated characteristics of elderly patients suffering from falls and fall-related characteristics.Methods Consecutive retrospective cross-sectional design spanned July 2006 to December 2008. Patient group: Information on all aged care inpatients who suffered from 1 or more falls was extracted from Incident information Management System (IIMS). Further details about the particular admission(s) were obtained from patients' medical records, e.g., patients' characteristics and circumstances surrounding the falls. Randomly selected aged care patients who did not suffer from a fall and who were discharged from the hospital in the same period served control group. Characteristics among patients with single fall and recurrent falls, as well as non-fallers were compared. Results Of the 438 falls evaluated, 71.9% occurred in patients' room and 18.9% in patients' bathroom/toilet. The common activities were moving/transferring and taking shower/toileting, respectively, 70.3%, 12.1% while occurring falls; and time of falls had a high peak during 9:00-11:00 a.m. Many were unassisted while falling. The common contributing factors for fall were intrinsic factors. Patients with recurrent falls were more likely to have lower Mini-Mental State Examination (MMSE) score. Logistic regression analysis showed length of stay longer than five weeks, dementia and stroke were independent risk factors for recurrent falls; and living in hostel/nursing home preadmission, needing assistance with mobility, cognitive impairment, stroke, incontinence and arthritis/osteoporosis were independent risk factors for fall.Conclusions In an aged care ward, falls are independently associated with recurrent factors. Cognitive impairment/dementia was a strong risk factor for falls, and main

    Full Text Available Background: PCV7 has been available in Italy since 2001, however only in 2005 national recommendations were issued and vaccination was implemented with different modalities by the Regions. Objectives: Aim of this study was to describe changes in serotype distribution and antibiotic susceptibility of S. pneumoniae from invasive pneumococcal diseases (IPD in the last decade. Study Design: S. pneumoniae isolates from IPD, collected through a national surveillance system, were serotyped and antibiotic susceptibility was determined by E-test. Data were analyzed according to age groups (5 years, >5-64 years, 65 years and to 3 time periods: prior, during and after PCV7 implementation (2001- 2003, 2006-2008 and 2009-2011. Results: The percentage of PCV7 serotypes (vaccine serotypes, VS decreased over the years not only in children (from 60% to 26% but also in the other age groups. Penicillin resistance was rather low in 2001-2003 (7-12%, but peaked in children in 2006-2008 (24%, and decreased in 2009-2011, while erythromycin resistance slightly decreased over the 3 periods. Conclusions: PCV7 use has largely impacted the epidemiology of S. pneumoniae in Italy, with a decrease in VS in all age groups.The impact of PCV 13, available in Italy since the end of 2010, requires future evaluations.

    Full Text Available BACKGROUND: Group A rotaviruses are the most common causative agent of acute gastroenteritis among children less than 5 years of age throughout the world. This sentinel surveillance study was aimed to obtain baseline data on the rotavirus G and P genotypes across Turkey before the introduction of a universal rotavirus vaccination program. METHODS: Rotavirus antigen-positive samples were collected from 2102 children less than 5 years of age who attended hospitals participating in the Turkish Rotavirus Surveillance Network. Rotavirus antigen was detected in the laboratories of participating hospitals by commercial serological tests such as latex agglutination, immunochromatographic test or enzyme immunoassay. Rotavirus G and P genotypes were determined by reverse transcription polymerase chain reaction (RT-PCR using consensus primers detecting the VP7 and VP4 genes, followed by semi-nested type-specific multiplex PCR. RESULTS: RT-PCR found rotavirus RNA in 1644 (78.2% of the samples tested. The highest rate of rotavirus positivity (38.7% was observed among children in the 13 to 24 month age group, followed by children in the age group of 25 to 36 months (28.3%. A total of eight different G types, six different P types, and 42 different G-P combinations were obtained. Four common G types (G1, G2, G3, and G9 and two common P types (P[8] and P[4] accounted for 95.1% and 98.8% of the strains, respectively. G9P[8] was the most common G/P combination found in 40.5% of the strains followed by G1P[8] (21.6%, G2P[8] (9.3%, G2P[4] (6.5%, G3P[8] (3.5%, and finally, G4P[8] (3.4%. These six common genotypes included 83.7% of the strains tested in this study. The rate of uncommon genotypes was 14%. CONCLUSION: The majority of the strains analyzed belonged to the G1-G4 and G9 genotypes, suggesting high coverage of current rotavirus vaccines. This study also demonstrates a dramatic increase in G9 genotype across the country.

    Introduction Rotavirus (RV) is a leading cause of acute gastroenteritis (AGE), affecting 95% of children below five years of age. Methods In this prospective, multi-center study, children below five years of age who were hospitalized or those who visited the emergency room (ER) due to AGE or who developed AGE at least 48 hours after hospitalization (nosocomial infection) and had a RV-positive stool sample were included (n=1,222). RV-positive samples were genotyped by reverse-transcriptase polymerase chain reaction. Results RV test results were available for 1,212 children (hospitalizations [n=677], ER visits [n=398] and nosocomial AGE cases [n=137]). Proportions of rotavirus gastroenteritis (RVGE) hospitalizations and ER visits were 51.70% (350/677; 95%CI: 47.86–55.52) and 36.18% (144/398; 95%CI: 31.45–41.12), respectively. Overall, 45.95% (494/1075) of all community-acquired AGE cases were due to RV. High numbers of RVGE cases were recorded between January and March. Most common genotypes were G9P[8] (34.27%) followed by G4P[8] (25.83%) and G1P[8] (23.02%). Of all community-acquired RVGE cases, the highest number of cases was observed in children aged 12–23 months. Median duration of hospitalization among RV-positive subjects was six days (range: 2–31 days). Incidence of nosocomial RVGE was 0.52 (95%CI: 0.45–0.60) cases per 1,000 child-days hospitalization. Median duration for additional hospitalization due to nosocomial RVGE was five days (range: 1–10). The highest burden of nosocomial RVGE was observed in children aged 12–23 months (42.34%, 58/137). Our findings confirm a high burden of acute RVGE disease in Romania and provide useful data to support the implementation of RV vaccination in Romania. Trial registration NCT01253967 PMID:24967217

    Cardiopulmonary resuscitation (CPR) is indicated in patients suffering from out-of-hospital cardiac arrest. Several studies suggest a sex- and age-based bias in the treatment of these patients. This particular bias may have a significant impact on the patient's outcome. However, the reasons for these findings are still unclear and discussed controversially. Therefore, the aim of this study was to retrospectively analyze treatment and out-of-hospital survival rates for potential sex- and age-based differences in patients requiring out-of-hospital CPR provided by an emergency physician in the city of Zurich, Switzerland.A total of 3961 consecutive patients (2003-2009) were included in this retrospective analysis to determine the frequency of out-of-hospital CPR and prehospital survival rate, and to identify potential sex- and age-based differences regarding survival and treatment of the patients.Seven hundred fifty-seven patients required CPR during the study period. Seventeen patients had to be excluded because of incomplete or inconclusive documentation, resulting in 743 patients (511 males, 229 females) undergoing further statistical analysis. Female patients were significantly older, compared with male patients (68 ± 18 [mean ± SD] vs 64 ± 18 years, P = .012). Men were resuscitated slightly more often than women (86.4% vs 82.1%). Overall out-of-hospital mortality rate was found to be 81.2% (492/632 patients) with no differences between sexes (82.1% for males vs 79% for females, odds ratio 1.039, 95% confidence interval 0.961-1.123). No sex differences were detected in out-of-hospital treatment, as assessed by the different medications administered, initial prehospital Glasgow Coma Scale, and prehospital suspected leading diagnosis.The data of our study demonstrate that there was no sex-based bias in treating patients requiring CPR in the prehospital setting in our physician-led emergency ambulance service.

    American association for the study of liver diseases (AASLD) and European Association for the Study of the Liver (EASL) guidelines recommend biannual hepatocellular carcinoma (HCC) screening for noncirrhotic patients with chronic hepatitis B infection (HBV), yet there are no data estimating surveillance rates or factors associated with surveillance. We performed a retrospective cohort study of US patients using the Truven Health Analytics databases from 2006 to 2010 and identified patients with noncirrhotic chronic HBV. Surveillance patterns were characterized using categorical and continuous outcomes, with the continuous measure of the proportion of time 'up to date' with surveillance (PUTDS), with the 6-month interval following each ultrasound categorized as 'up to date'. During a median follow-up of 26.0 (IQR: 16.2-40.0) months among 4576 noncirrhotic patients with chronic HBV (median age: 44 years, IQR: 36-52), only 306 (6.7%) had complete surveillance (one ultrasound every 6-month interval), 2727 (59.6%) incomplete (≥1 ultrasound) and 1543 (33.7%) none. The mean PUTDS was 0.34 ± 0.29, and the median was 0.32 (IQR: 0.03-0.52). In multinomial logistic regression models, patients diagnosed by a nongastroenterologist were significantly less likely to have complete surveillance (P HIV (P regression models, nongastroenterologist provider, health insurance subtype, HBV/HIV coinfection, rural status and metabolic syndrome were independently associated with decreased surveillance. Patients with HIV had an absolute decrease in the PUTDS of 0.24, while patients in less populated rural areas had an absolute decrease of 0.10. HCC surveillance rates in noncirrhotic patients with chronic HBV in the United States are poor and lower than reported rates of HCC surveillance in cirrhotic patients. PMID:25581816

    During 2004–2009, the Centers for Disease Control and Prevention (CDC) partnered with 39 national governments to strengthen global influenza surveillance. Using World Health Organization data and program evaluation indicators collected by CDC in 2013, we retrospectively evaluated progress made 4–9 years after the start of influenza surveillance capacity strengthening in the countries. Our results showed substantial increases in laboratory and sentinel surveillance capacities, which are essential for knowing which influenza strains circulate globally, detecting emergence of novel influenza, identifying viruses for vaccine selection, and determining the epidemiology of respiratory illness. Twenty-eight of 35 countries responding to a 2013 questionnaire indicated that they have leveraged routine influenza surveillance platforms to detect other pathogens. This additional surveillance illustrates increased health-system strengthening. Furthermore, 34 countries reported an increased ability to use data in decision making; data-driven decisions are critical for improving local prevention and control of influenza around the world.

    This section of the 1994 Hanford Site Environmental Report summarizes the air surveillance and monitoring programs currently in operation at that Hanford Site. Atmospheric releases of pollutants from Hanford to the surrounding region are a potential source of human exposure. For that reason, both radioactive and nonradioactive materials in air are monitored at a number of locations. The influence of Hanford emissions on local radionuclide concentrations was evaluated by comparing concentrations measured at distant locations within the region to concentrations measured at the Site perimeter. This section discusses sample collection, analytical methods, and the results of the Hanford air surveillance program. A complete listing of all analytical results summarized in this section is reported separately by Bisping (1995).

    Full Text Available From January 1990 to December 2006, Helen Keller International implemented the Nutritional Surveillance Project (NSP in Bangladesh, which has been used to conduct regular surveillance and special surveys to provide information on health and nutritional status of children and mothers, and report on the coverage and impact of nutrition and health programs in Bangladesh. The Government of Bangladesh (GOB distributes vitamin A Capsule (VAC among children aged 12–59 months biannually. The NSP data was analyzed to assess VAC coverage and to explore which children were less likely to receive a VAC in order to help GOB identify necessary modifications aimed at higher coverage of VAC among all eligible children. Results showed that coverage among girls and boys was not different (P=0.970. However, coverage was consistently lower among children aged 12-23 months compared to older children (24–59 months (P≤0.001 in each of the distribution rounds. Coverage among children from poorer households was lower than among children from wealthiest households (P<0.001, with the extent of this difference varying by round. Coverage was significantly higher if households had had contact with a government health assistant in the last month (P<0.001; and among households who owned a radio or a TV compared to those who did not. The VAC distribution campaign needs to be strengthened to cover the children who are currently not reached; especially younger children, children living in underserved regions, children from poorer households and from households with less contact with health service providers or mass media.De janvier 1990 à décembre 2006, l’ONG Helen Keller International a mis en oeuvre le projet Nutritional Surveillance Project (NSP au Bangladesh.

    Biological weapons are within reach of individuals, small groups, terrorist organizations, as well as nations. With pervasive integration of civilian and military populations worldwide, the ill winds of biological warfare stand to affect military troops and civilians alike. A variety of technologies are emerging - such as pathogen detection devices, streaming internet characterization tools, information exploitation techniques, automated feature extraction, and ubiquitous wireless communication - that can help. These technologies, if taken together within an integrated analytical framework, could make possible the monitoring of diverse parameters that may indicate a change in the state of health of a given population - either the emergence of a naturally occurring disease or the outbreak of a disease as a result of hostile intent. This presentation will discuss the application of new information surveillance tools and technologies as they apply to health and disease monitoring, particularly within the context of potential terrorist or hostile nation use of biological warfare. Although discussed within the specific context of health surveillance, the tools and processes described here are generally applicable within other domains of subject matter expertise.

    A prognostic model for relapse risk in stage I seminoma managed by surveillance after orchiectomy has been developed but has not been independently validated. Individual data on 685 stage I seminoma surveillance patients managed between 1998 and 2005 at three cancer centers were retrospectively...... analyzed. Variables including age and pathology of the primary tumor: small vessel invasion, tumor size, and invasion of rete testis were analyzed. Specifically median tumor size and rete testis invasion was tested to evaluate the performance of the published model. Median follow-up was 3.85 years (0...... 3 cm) was a predictor for relapse, HR 1.87 (95% CI 1.15, 3.06), whereas rete testis invasion HR 1.36, (95% CI 0.81, 2.28) was not statistically significant. The 3-year relapse risk based on the primary tumor size alone increased from 9% for 1 cm primary tumor to 26% for 8 cm tumor. A clinically...

    2011-12-01

    Full Text Available The task of this paper is to explore and compare ways of defining surveillance. In order to give meaning to concepts that describe the realities of society, social theory is needed. Therefore social theory is employed in this paper for discussing ways of defining surveillance. “Living in ‘surveillance societies’ may throw up challenges of a fundamental – ontological – kind” (Lyon, 1994, p.19. Social theory is a way of clarifying such ontological questions that concern the basic nature and reality of surveillance. A distinction between neutral and negative concepts of surveillance is drawn. Some potential disadvantages of neutral concepts of surveillance are outlined. This paper wants to contribute to the discussion of how to best define surveillance and wants to show that one of the main theoretical differences and questions in surveillance theory is if surveillance should be defined as a negative or a neutral concept.

To address the limitations of traditional indicators, we propose a novel severity index based on influenza age dynamics estimated from routine physician diagnosis data that can be used retrospectively and for early warning. METHODS: We developed a quantitative 'ground truth......' severity benchmark that synthesizes multiple traditional severity indicators from publicly available influenza surveillance data in the United States. Observing that the age distribution of cases may signal severity early in an epidemic, we constructed novel retrospective and early warning severity indexes...... based on the relative risk of influenza-like illness (ILI) among working-age adults to that among school-aged children using weekly outpatient medical claims. We compared our relative risk-based indexes to the composite benchmark and estimated seasonal severity for flu seasons from 2001-02 to 2008...

    As life expectancy increases and spinal imaging techniques improve, surgery is being increasingly viewed as a therapeutic alternative for symptomatic lumbar spinal stenosis in patients older than 80 years. Thirty-four patients (21 men and 13 women) who had surgery for lumbar spinal stenosis in our department between 1979 and 1994 were studied retrospectively. The most common initial symptoms were walking-related disorders (n = 29) and sciatica or femoral neuralgia (n = 34). All 34 patients underwent laminectomy at one or more levels. Ten patients also had a herniated disk. There were no deaths and only two patients had serious complications (persistent foot drop in one and left-sided hemiplegia in the other). Results were evaluated immediately after surgery and after three and 12 months. The overall result on pain and walking-related disorders was good in 53% of cases, acceptable in 32%, and poor in 15%. Our data suggest that surgery is a reasonable alternative in symptomatic elderly patients who are in good general health. Satisfactory results can be obtained although disabling complications can occur. PMID:8731237

    Full Text Available Various types of sensors-visible, passive night vision, infrared, synthetic aperture radar, etc can be used for desert surveillance. The surveillance capability of these sensors depends to a large extent, on various atmospheric effects, viz., absorption, scattering, aerosol, turbulence, and optical mirage. In this paper, effects of various atmospheric phenomena on the transmission of signals, merits and demerits of different means of surveillance under desert environmental conditions are discussed. Advanced surveillance techniques, ie, multisensor fusion, multi and hyperspectral imaging, having special significance for desert surveillance, have also been discussed.

    Uldam, Julie

    As activists move from alternative media platforms to commercial social media platforms they face increasing challenges in protecting their online security and privacy. While government surveillance of activists is well-documented in both scholarly research and the media, corporate surveillance of...... activists remains under-researched. This presentation explores visibility as a prerequisite and an obstacle to political participation. The dual capacity of visibility in social media enables both surveillance and counter-surveillance by making not only the surveilled actor, but also the surveilling actor...... visible. It thus enables activists to monitor and expose corporate misconduct, but simultaneously renders them vulnerable to surveillance from corporations. In this presentation, I examine these practices and discuss their implications for political participation by drawing on examples of companies...

    Alexandre Sérgio da Costa Braga

    2013-01-01

    Full Text Available INTRODUTION: A major concern with the visceral leishmaniasis (VL is its high lethality rate, even with proper treatment. Low age, prior malnutrition, disease duration prior to diagnosis, severe anemia, fever for more than 60 days, diarrhea and jaundice are known poor prognostic factors. The goals of this study are to describe the clinical and laboratory characteristics of VL among children under 12 years of age and to identify the factors associated with VL poor outcome. METHODS: Two hundred and fifty children under 12 years of age with confirmed VL admitted to Hospital João Paulo II (FHEMIG, Belo Horizonte, Brazil, between January 2001 and December 2005 were evaluated retrospectively. The primary outcome was the poor clinical evolution: sepsis, and/or pneumonia, and/or urinary tract infection, and/or of bleeding (expect epistaxis, and/or severe neutropenia (neutrophil < 500 cells/mm3. Odds ratio (crude and adjusted and its 95% confidence interval for each variable were calculated. Values less than 0.05 were considered significant. RESULTS: Average age was 3.3 years (3.6 months-11.6 years, 71.2% were younger than 5 years and 47.2% lived in Metropolitan Area of Belo Horizonte. The mean fatality rate was 3.6%. Sixty-six (26.4% patients presented poor evolution. After a multivariate analysis, age <18 months, abnormal respiratory physical examination on hospital admission, and platelets <85,000/mm3 remained associated with increased chance of poor evolution. CONCLUSIONS: The results suggest that patients aged between 12 and 18 months, with platelet counts bellow 85,000/mm3, and respiratory abnormalities at admission should be considered potentially severe.

  4. Epidemiology and viral etiology of the influenza-like illness in corsica during the 2012-2013 Winter: an analysis of several sentinel surveillance systems.

    Laëtitia Minodier

    Full Text Available Influenza-like illness (ILI surveillance is important to identify circulating and emerging/reemerging strains and unusual epidemiological trends. The present study aimed to give an accurate picture of the 2012-2013 ILI outbreak in Corsica by combining data from several surveillance systems: general practice, emergency general practice, hospital emergency units, intensive care units, and nursing homes. Twenty-eight respiratory viruses were retrospectively investigated from patients in general practice with ILI. Sequence analysis of the genetic changes in the hemagglutinin gene of influenza viruses (A(H1N1pdm2009, A(H3N2 and B was performed. The trends in ILI/influenza consultation rates and the relative illness ratios (RIRs of having an ILI consultation were estimated by age group for the different surveillance systems analyzed. Of the 182 ILI patients enrolled by general practitioners, 57.7% tested positive for influenza viruses. Phylogenetic analyses suggested a genetic drift for influenza B and A(H3N2 viruses. The ILI/influenza surveillance systems showed similar trends and were well correlated. In accordance with virological data, the RIRs of having an ILI consultation were highest among the young (<15 years old and decreased with age. No clusters of acute respiratory illness were declared by the sentinel nursing homes. This study is noteworthy in that it is the first extensive description of the 2012-2013 ILI outbreak in Corsica as monitored through several surveillance systems. To improve ILI surveillance in Corsica, a consortium that links together the complementary regional surveillance ILI systems described here is being implemented.

    Full Text Available Objective: To study the distribution of weight for age standard score (Z score in pediatric cardiac surgery and its effect on in-hospital mortality. Introduction: WHO recommends Standard Score (Z score to quantify and describe anthropometric data. The distribution of weight for age Z score and its effect on mortality in congenital heart surgery has not been studied. Methods: All patients of younger than 5 years who underwent cardiac surgery from July 2007 to June 2013, under single surgical unit at our institute were enrolled. Z score for weight for age was calculated. Patients were classified according to Z score and mortality across the classes was compared. Discrimination and calibration of the for Z score model was assessed. Improvement in predictability of mortality after addition of Z score to Aristotle Comprehensive Complexity (ACC score was analyzed. Results: The median Z score was -3.2 (Interquartile range -4.24 to -1.91] with weight (mean±SD of 8.4 ± 3.38 kg. Overall mortality was 11.5%. 71% and 52.59% of patients had Z score < -2 and < -3 respectively. Lower Z score classes were associated with progressively increasing mortality. Z score as continuous variable was associated with O.R. of 0.622 (95% CI- 0.527 to 0.733, P < 0.0001 for in-hospital mortality and remained significant predictor even after adjusting for age, gender, bypass duration and ACC score. Addition of Z score to ACC score improved its predictability for in-hosptial mortality (δC - 0.0661 [95% CI - 0.017 to 0.0595, P = 0.0169], IDI- 3.83% [95% CI - 0.017 to 0.0595, P = 0.00042]. Conclusion: Z scores were lower in our cohort and were associated with in-hospital mortality. Addition of Z score to ACC score significantly improves predictive ability for in-hospital mortality.

  7. Aging.

    Park, Dong Choon; Yeo, Seung Geun

    2013-09-01

    Aging is initiated based on genetic and environmental factors that operate from the time of birth of organisms. Aging induces physiological phenomena such as reduction of cell counts, deterioration of tissue proteins, tissue atrophy, a decrease of the metabolic rate, reduction of body fluids, and calcium metabolism abnormalities, with final progression onto pathological aging. Despite the efforts from many researchers, the progression and the mechanisms of aging are not clearly understood yet. Therefore, the authors would like to introduce several theories which have gained attentions among the published theories up to date; genetic program theory, wear-and-tear theory, telomere theory, endocrine theory, DNA damage hypothesis, error catastrophe theory, the rate of living theory, mitochondrial theory, and free radical theory. Although there have been many studies that have tried to prevent aging and prolong life, here we introduce a couple of theories which have been proven more or less; food, exercise, and diet restriction.

    Vaccines are increasingly targeted toward women of reproductive age, and vaccines to prevent influenza and pertussis are recommended during pregnancy. Prelicensure clinical trials typically have not included pregnant women, and when they are included, trials cannot detect rare events. Thus, postmarketing vaccine safety assessments are necessary. However, analysis of observational data requires detailed assessment of potential biases. Using data from 8 Vaccine Safety Datalink sites in the United States, we analyzed the association of monovalent H1N1 influenza vaccine (MIV) during pregnancy with preterm birth (variable access to vaccines, the time-dependent nature of exposure to vaccination within pregnancy (immortal time bias), and confounding from baseline differences between vaccinated and unvaccinated women. We found a strong protective effect of vaccination on preterm birth (relative risk = 0.79, 95% confidence interval: 0.74, 0.85) when we ignored potential biases and no effect when accounted for them (relative risk = 0.91; 95% confidence interval: 0.83, 1.0). In contrast, we found no important biases in the association of MIV with small-for-gestational-age birth. Investigators conducting studies to evaluate birth outcomes after maternal vaccination should use statistical approaches to minimize potential biases. PMID:27449414

    The global movement of people and goods has increased the risk of biosecurity threats and their potential to incur large economic, social, and environmental costs. Conventional manual biosecurity surveillance methods are limited by their scalability in space and time. This article focuses on autonomous surveillance systems, comprising sensor networks, robots, and intelligent algorithms, and their applicability to biosecurity threats. We discuss the spatial and temporal attributes of autonomous surveillance technologies and map them to three broad categories of biosecurity threat: (i) vector-borne diseases; (ii) plant pests; and (iii) aquatic pests. Our discussion reveals a broad range of opportunities to serve biosecurity needs through autonomous surveillance. PMID:25744760

    Full Text Available Aim. To describe the natural history of small renal mass on active surveillance and identify parameters that could help in predicting the need for intervention in patients with small renal masses undergoing active surveillance. We also discuss the need for renal biopsy in the management of these patients. Methods. A retrospective analysis of 78 renal masses ≤4 cm diagnosed at our Urology Department at Bnai Zion Medical Center between September 2003 and March 2012. Results. Seventy patients with 78 small renal masses were analyzed. The mean age at diagnosis was 68 years (47–89. The mean follow-up period was 34 months (12–112. In 54 of 78 masses there was a growth of at least 2 mm between imaging on last available follow-up and diagnosis. Eight of the 54 (15% masses which grew in size underwent a nephron-sparing surgery, of which two were oncocytomas and six were renal cell carcinoma. Growth rate and mass diameter on diagnosis were significantly greater in the group of patients who underwent a surgery. Conclusions. Small renal masses might eventually be managed by active surveillance without compromising survival or surgical approach. All masses that were eventually excised underwent a nephron-sparing surgery. None of the patients developed metastases.

    2015-07-01

    There is wide variation in how exposure to violence is conceptualized. Perceptions of ordinary violence are linked to people's actual experiences, which may be direct, indirect, observed, or vicarious, and all through filters of gender, class, community, and culture. Event-recall interviews were conducted among a convenience sample of Swedish males (n = 132) and females (n = 202) aged 6 to 45 years. Respondents spontaneously recalled 703 events (averaging 2.3 events for males, 2.1 for females). For men, 93% of events were male(s)-on-male(s), 2% female-on-female, and 2% male(s)-on-female(s). For women, 42% of events were male(s)-on-male(s), 19% female(s)-on-female(s), 24% male(s)-on-females, and 10% female(s)-on-male(s). Interviewee's roles differed. Of males, 17% were aggressors, 40% victims, and 43% observers. Of females, 12% were aggressors, 30% victims, and 58% observers. For males, there was a significant increase in degree of seriousness of events from junior-, to high school, to college. For females, events became more serious as interviewees progressed from aggressor to victim to observer. For males, violent events between strangers were significantly more serious than all other combinations of acquaintanceship. Most recently recalled events were the most serious for males (no effect for females). Participation in sports was linked to seriousness of events recalled by females, events being described as more serious by females who participated in sports, this effect being stronger for those females who participated in contact/collision and self-defense sports. The significant correlation between trauma and seriousness is nearly twice as strong for females which might be taken as an indication of stronger moral pathos. PMID:25304671

    Soil sampling and analysis evaluates long-term contamination trends and monitors environmental radionuclide inventories. This section of the 1994 Hanford Site Environmental Report summarizes the soil and vegetation surveillance programs which were conducted during 1994. Vegetation surveillance is conducted offsite to monitor atmospheric deposition of radioactive materials in areas not under cultivation and onsite at locations adjacent to potential sources of radioactivity.

    The goal of this manuscript was twofold and a two-study approach was conducted. The first study aimed to expose the anthropometrical, physical performance and motor coordination characteristics that influence drop out from a high-level soccer training program in players aged 8-16 years. The mixed-longitudinal sample included 388 Belgian youth soccer players who were assigned to either a 'club group' or a 'drop out group'. In the second study, cross-sectional data of anthropometry, physical performance and motor coordination were retrospectively explored to investigate which characteristics influence future contract status (contract vs. no contract group) and first-team playing time for 72 high-level youth soccer players (mean age=16.2 y).Generally, club players outperformed their drop out peers for motor coordination, soccer-specific aerobic endurance and speed. Anthropometry and estimated maturity status did not discriminate between club and drop out players. Contract players jumped further (p=0.011) and had faster times for a 5m sprint (p=0.041) than no contract players. The following prediction equation explains 16.7% of the variance in future playing minutes in adolescent youth male soccer players: -2869.3 + 14.6 * standing broad jump.Practitioners should include the evaluation of motor coordination, aerobic endurance and speed performances to distinguish high-level soccer players further succeeding a talent development program and future drop out players, between 8 and 16 years. From the age of 16 years, measures of explosivity are supportive when selecting players into a future professional soccer career. PMID:25474335

    Since several studies have demonstrated the inadequate diagnostic performance of mammography in high risk women, over the past two decades, different breast imaging tests have been evaluated as additional diagnostic methods to mammography, and the most relevant ones are the techniques that do not imply the use of X-rays, considering the young age of these patients and the higher radio-sensitivity. Breast dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has risen growing interest not only because of the absence of use of X-rays, but also because it provides morpho-functional features, which may depict biological characteristics of breast tissues, including invasive and in situ cancers. Different multicenter non-randomized prospective studies aimed to evaluate breast DCE-MRI as an integral part of surveillance programs, agreed about the evidence that in high risk women screening with DCE-MRI is more effective than either mammography and/or ultrasound. Moreover, this modality leads to the identifications of cancers at a more favorable stage, allowing a real advantage in terms of tumor size and nodal involvement. The medical community is evaluating to suggest DCE-MRI alone as screening modality in high-risk women, as it was reported that in these cases the sensitivity of MRI plus conventional imaging was not significantly higher than that of MRI alone. Breast MRI is now recommended as part of screening program for high risk women by both European and American guidelines. PMID:26924173

    Objectives There are very little data on pre-excitation syndrome (PS) in the elderly. We investigated the influence of advancing age on clinical presentation, treatment and long-term outcome of PS. Setting Single-centre retrospective study of patient files. Participants In all, 961 patients (72 patients ≥60 years (mean 68.5±6), 889 patients <60 years (mean 30.5±14)) referred for overt pre-excitation and indication for electrophysiological study (EPS) were followed for 5.3±5 years. Usual care included 24 h Holter monitoring, echocardiography and EPS. Patients underwent accessory pathway (AP) ablation if necessary. Primary and secondary outcome measures Occurrence of atrial fibrillation (AF) or procedure-induced adverse event. Results Electrophysiological data and recourse to AP ablation (43% vs 48.5%, p=0.375) did not significantly differ between the groups. Older patients more often had symptomatic forms (81% vs 63%, p=0.003), history of spontaneous AF (8% vs 3%, p=0.01) or adverse presentation (poorly tolerated arrhythmias: 18% vs 7%, p=0.0009). In multivariable analysis, patients ≥60 years had a significantly higher risk of history of AF (OR=4.2, 2.1 to 8.3, p=0.001) and poorly tolerated arrhythmias (OR=3.8, 1.8 to 8.1, p=0.001). Age ≥60 years was associated with an increased major AP ablation complication risk (10% vs 1.9%, p=0.006). During follow-up, occurrence of AF (13.9% vs 3.6%, p<0.001) and incidence of poorly tolerated tachycardia (4.2% vs 0.6%, p=0.001) were more frequent in patients ≥60 years, although frequency of ablation failure or recurrence was similar (20% vs 15.5%, p=0.52). In multivariable analysis, patients ≥60 years had a significantly higher risk of AF (OR=2.9, 1.2 to 6.8, p≤0.01). Conclusions In this retrospective monocentre study, patients ≥60 years referred for PS work up appeared at higher risk of AF and adverse presentation, both prior and after the work up. These results suggest that, in elderly

    Full Text Available Background: To determine disparity in mortality-related factors in 1-59 months children across Iran using hospital records of emergency units. Materials and Methods: After designing and validating a national questionnaire for mortality data collection of children 1-59 months, all 40 medical universities has been asked to fill in the questionnaires and return to the main researcher in the Ministry of Health and Medical Education. Age and sex of deceased children, the type of health center, staying more than 2 h in emergency unit, the reason of prolonged stay in emergency, having emergency (risk signs, vaccination, need to blood transfusion, need to electroshock and so on have also been collected across the country. There was also a comparison of children based on their BMI. Chi-square test has been applied for nominal and ordinal variables. ANOVA and t-student test have been used for measuring the difference of continuous variables among groups. Results: Mortality in 1-59 months children was unequally distributed across Iran. The average month of entrance to hospital was June, the average day was 16 th of month, and the average hour of entrance to hospital was 14:00. The average of month, day and hour for discharge was July, 16, and 14:00, respectively. The hour of discharge was statistically significant between children with and without risk signs. More than half (54% of patients had referred to educational hospital emergency units. There were no statistically significant differences between children with and without emergency signs. There were statistically significant differences between children with and without emergency signs in age less than 24 months (0.034, nutrition situation ( P = 0.031, recommendation for referring ( P = 0.013, access to electroshock facilities ( P = 0.026, and having successful cardiopulmonary resuscitation ( P = 0.01.

    Full Text Available Creative works are now increasingly distributed as digital “content” through the internet, and copyright law has created powerful incentives to monitor and control these flows. This paper analyzes the surveillance industry that has emerged as a result. Copyright surveillance systems identify copyright infringement online and identify persons to hold responsible for infringing acts. These practices have raised fundamental questions about the nature of identification and attribution on the internet, as well as the increasing use of algorithms to make legal distinctions. New technologies have threatened the profits of some media industries through copyright infringement, but also enabled profitable forms of mass copyright surveillance and enforcement. Rather than a system of perfect control, copyright enforcement continues to be selective and uneven, but its broad reach results in systemic harm and provides opportunities for exploitation. It is only by scrutinizing copyright surveillance practices and copyright enforcement measures that we can evaluate these consequences.

    Background. The use of surveillance imaging in children with medulloblastoma has been criticised. The aim of this study was to determine what proportion of relapses are detected by surveillance and whether these are found at a relatively favourable stage. Methods. This study was a retrospective review of the medical charts and imaging studies of 89 patients treated at a single children's cancer centre. Relapse was defined as evidence of an increase in volume of residual tumour of greater than 25% or the presence of metastases, or new onset of positive CSF cytology. Relapse was termed symptomatic if it was diagnosed by tests performed because of new symptoms that occurred in the interval between surveillance examinations. Asymptomatic relapse was diagnosed solely on the basis of surveillance imaging. Survival time to relapse was calculated from the date of the first surgical procedure. Results. Surveillance imaging detected 17 (71%) of the 24 relapses that occurred later than 6 months after diagnosis. All seven patients who presented with symptoms between scans have died, with a median survival from relapse of 5 months. Median survival from relapse in the patients detected by surveillance was 44 months, and four remain alive at 44-75 months. The patients detected by surveillance tended to have less advanced disease, which was more amenable to salvage therapy. Conclusion. This type of study cannot prove that surveillance imaging improves survival in children with medulloblastoma because of the effects of lead time and length biases. Despite this, surveillance does appear to be effective in detecting potentially curable medulloblastoma relapses and should be offered to all patients. (orig.)

    Full Text Available Lars Lund,1,2 Niels Svolgaard,1 Mads Hvid Poulsen1 1Department of Urology, Odense University Hospital, 2Clinical Institute, Southern University of Southern Denmark, Odense, Denmark Abstract: The objective of this paper is to review the current recommendations for active surveillance in prostate cancer from the present prospective studies. Worldwide, there are increasing numbers of men with prostate cancer. It is now accepted as standard care that a number of men with favorable-risk disease can be followed with active surveillance. In 1995, the first prospective studies were initiated to assess the feasibility of active surveillance, in which the decision to intervene was determined by prostate-specific antigen and/or histological progression. The strategy was to provide therapy individualized to the biological behavior of the cancer. Clinical trials assessing active surveillance have usually included patients younger than 70 years of age, although the guidelines have changed over time for Gleason score and prostate-specific antigen, eg, doubling time, thereby changing the indication for active treatment. The present review focuses on patient selection, prospective studies reported in the literature, and future directions. Keywords: active surveillance, prostate cancer, prospective studies, review

    In September of 2009, a Tri-Lab team was formed to develop a set of metrics relating to the NNSA nuclear weapon surveillance program. The purpose of the metrics was to develop a more quantitative and/or qualitative metric(s) describing the results of realized or non-realized surveillance activities on our confidence in reporting reliability and assessing the stockpile. As a part of this effort, a statistical sub-team investigated various techniques and developed a complementary set of statistical metrics that could serve as a foundation for characterizing aspects of meeting the surveillance program objectives. The metrics are a combination of tolerance limit calculations and power calculations, intending to answer level-of-confidence type questions with respect to the ability to detect certain undesirable behaviors (catastrophic defects, margin insufficiency defects, and deviations from a model). Note that the metrics are not intended to gauge product performance but instead the adequacy of surveillance. This report gives a short description of four metrics types that were explored and the results of a sensitivity study conducted to investigate their behavior for various inputs. The results of the sensitivity study can be used to set the risk parameters that specify the level of stockpile problem that the surveillance program should be addressing.

Thus in this paper we have come up with efficient proposals to upgrade the approach for Camera based Surveillance Architecture for security and Administration. This renewed approach is essentially based upon RFID technology where we are utilizing RFID tags and their readers as basic components. Unlike Camera-based surveillance, RFID-based approach can monitor and administer a quarter not only within some region of visibility but can efficiently do the same for locating the individuality (through Dynamic Surveillance as explained further. This approach emphasizes not only on overcoming the demerits of observation-based supervision, but it presents easier and effective monitoring methodologies using radio waves and their usable features in security and administration for areas with consumer pour out.

    Results from the 9975 Surveillance Program at the Savannah River Site (SRS) are summarized for justification to extend the life of the 9975 packages currently stored in the K-Area Materials Storage (KAMS) facility from 10 years to 15 years. This justification is established with the stipulation that surveillance activities will continue throughout this extended time to ensure the continued integrity of the 9975 materials of construction and to further understand the currently identified degradation mechanisms. The current 10 year storage life was developed prior to storage. A subsequent report was later used to extend the qualification of the 9975 shipping packages for 2 years for shipping plus 10 years for storage. However the qualification for the storage period was provided by the monitoring requirements of the Storage and Surveillance Program. This report summarizes efforts to determine a new safe storage limit for the 9975 shipping package based on the surveillance data collected since 2005 when the surveillance program began. KAMS is a zero-release facility that depends upon containment by the 9975 to meet design basis storage requirements. Therefore, to confirm the continued integrity of the 9975 packages while stored in KAMS, a 9975 Storage and Surveillance Program was implemented alongside the DOE required Integrated Surveillance Program (ISP) for 3013 plutonium-bearing containers. The 9975 Storage and Surveillance Program performs field surveillance as well as accelerated aging tests to ensure any degradation due to aging, to the extent that could affect packaging performance, is detected in advance of such degradation occurring in the field. The Program has demonstrated that the 9975 package has a robust design that can perform under a variety of conditions. As such the primary emphasis of the on-going 9975 Surveillance Program is an aging study of the 9975 Viton(reg.sign) GLT containment vessel O-rings and the Celotex(reg.sign) fiberboard thermal

    Fatal falls are frequent and inhomogeneous events and affect every age. The criminalistic classification can often only be done on the basis of extensive investigations and the autopsy results. We retrospectively surveyed 291 cases of fatal falls on which a post-mortem examination had been carried out in the institutes of Forensic Medicine in Bonn and Greifswald. In large part, these cases are falls from height (n=123) and ground-level falls (n=122). These are compared to fatal falls down a stairs (n=46); the analysis is confined to injuries to the cranium. In ground-level falls the injury pattern in falls under the influence of alcohol differs from that of falls with no alcohol in the case history: all injuries are seen in higher relative frequency in casualties after the consumption of alcohol. In falls from height, the previous consumption of alcohol did not influence the injury pattern; the intracranial traumas are seen in decreasing frequency with increasing heights. The aim of this retrospective analysis is to present injury patterns and influencing factors like fall heights and alcohol for the different kinds of falls on the basis of our collective and to demonstrate similarities and differences between the subgroups.

    In October 1989, the Hungarian National Institute of Hygiene initiated the Children's Acute Respiratory Morbidity (CHARM) Surveillance System to assess the association between nine reportable respiratory diseases and air pollution. The weekly number of physician-diagnosed, reportable respiratory diseases among four age groups of children (less than 1, 1-2, 3-5, and 6-14 years) was tabulated for Sopron, a city with 60,000 residents. We calculated the proportion of diseases occurring during weeks with low, moderate, and high sulfur dioxide (SO2) and nitrogen dioxide (NO2) concentrations. The weekly averages of the 24-hour median SO2 concentrations were divided into thirds at less than or equal to 17.6, greater than 17.6 to less than or equal to 26.3, and greater than 26.3 micrograms/m3 (range: 0.9-79.6 micrograms/m3), and the NO2 concentrations at less than or equal to 29.8, greater than 29.8 to less than or equal to 44.1, and greater than 44.1 micrograms/m3 (range: 4.2-90.1 micrograms/m3). During 1990, 11,474 respiratory disease cases occurred among the 4,020 children less than 15 years of age living in Sopron and monitored by the CHARM system. The two most frequently reported disease categories were rhinitis/tonsillitis/pharyngitis (71.5%) and acute bronchitis (8.5%). Sixty-seven percent of pneumonia cases occurred when SO2 concentrations were highest. We found no association between levels of NO2 and respiratory diseases. The CHARM Surveillance System may characterize more fully which groups of children develop particular respiratory diseases following exposure to air pollution.

    The generation of cells in the human body has been difficult to study and our understanding of cell turnover is limited. Extensive testing of nuclear weapons resulted in a dramatic global increase in the levels of the isotope {sup 14}C in the atmosphere, followed by an exponential decrease after the test ban treaty in 1963. We show that the level of {sup 14}C in genomic DNA closely parallels atmospheric levels, and can be used to establish the time point when the DNA was synthesized and cells were born. We use this strategy to determine the age of cells in the cortex of the adult human brain, and show that whereas non-neuronal cells are exchanged, occipital neurons are as old as the individual, supporting the view that postnatal neurogenesis does not take place in this region. Retrospective birth dating is a generally applicable strategy that can be used to measure cell turnover in man under physiological and pathological conditions.

    Children with hepatoblastoma routinely undergo repetitive surveillance imaging, with CT scans for several years after therapy, increasing the risk of radiation-induced cancer. The purpose of this study was to determine the utility of surveillance CT scans compared to serum alpha-fetoprotein (AFP) levels for the detection of hepatoblastoma relapse. This was a retrospective study of all children diagnosed with AFP-positive hepatoblastoma from 2001 to 2011 at a single institution. Twenty-six children with hepatoblastoma were identified, with a mean age at diagnosis of 2 years 4 months (range 3 months to 11 years). Mean AFP level at diagnosis was 132,732 ng/ml (range 172.8-572,613 ng/ml). Five of the 26 children had hepatoblastoma relapse. A total of 105 imaging exams were performed following completion of therapy; 88 (84%) CT, 8 (8%) MRI, 5 (5%) US and 4 (4%) FDG PET/CT exams. A total of 288 alpha-fetoprotein levels were drawn, with a mean of 11 per child. The AFP level was elevated in all recurrences and no relapses were detected by imaging before AFP elevation. Two false-positive AFP levels and 15 false-positive imaging exams were detected. AFP elevation was found to be significantly more specific than PET/CT and CT imaging at detecting relapse. We recommend using serial serum AFP levels as the preferred method of surveillance in children with AFP-positive hepatoblastoma, reserving imaging for the early postoperative period, for children at high risk of relapse, and for determination of the anatomical site of clinically suspected recurrence. Given the small size of this preliminary study, validation in a larger patient population is warranted. (orig.)

    2012-01-01

    Gastrointestinal (GI) malignancies are notorious for frequently progressing to advanced stages even in the absence of serious symptoms,thus leading to delayed diagnoses and dismal prognoses.Secondary prevention of GI malignancies through early detection and treatment of cancer-precursor/premalignant lesions,therefore,is recognized as an effective cancer prevention strategy.In order to efficiently detect these lesions,systemic application of screening tests (surveillance) is needed.However,most of the currently used non-invasive screening tests for GI malignancies (for example,serum markers such as alpha-fetoprotein for hepatocellular carcinoma,and fecal occult blood test,for colon cancer) are only modestly effective necessitating the use of highly invasive endoscopy-based procedures,such as esophagogastroduodenoscopy and colonoscopy for screening purposes.Even for hepatocellular carcinoma where non-invasive imaging (ultrasonography) has become a standard screening tool,the need for repeated liver biopsies of suspicious liver nodules for histopathological confirmation can't be avoided.The invasive nature and high-cost associated with these screening tools hinders implementation of GI cancer screening programs.Moreover,only a small fraction of general population is truly predisposed to developing GI malignancies,and indeed needs surveillance.To spare the average-risk individuals from superfluous invasive procedures and achieve an economically viable model of cancer prevention,it's important to identify cohorts in general population that are at substantially high risk of developing GI malignancies (riskstratification),and select suitable screening tests for surveillance in these cohorts.We herein provide a brief overview of such high-risk cohorts for different GI malignancies,and the screening strategies that have commonly been employed for surveillance purpose in them.

    Full Text Available The use of microwave spectrum is widespread due to its convenience. Therefore, enormous amount of information is available in the free space channel. Obviously, mining this channel for surveillance is quite common. Airborne surveillance offers significant advantages in military operations. This paper talks of the usage of microwaves in airborne surveillance systems, in general, and in the Indian airborne early warning and control (AEW&C System, in particular. It brings out the multiple sub-systems onboard the aircraft comprising the AEW&C system and their spectral coverage. Co-location of several systems has its own problems and resolving them in terms of geometric location, frequency band and time of operation are covered. AEW&C, being an airborne system, has several other requirements  including minimal weight, volume and power considerations, lightning protection, streamlining, structural integrity, thermal management, vibration tolerance, corrosion prevention, erosion resistance, static charge discharge capability, bird strike resilience, etc. The methods adopted to cater to all these requirements in the microwave systems that are used in the AEW&C system are discussed. Paper ultimately speaks of the microwave systems that are designed and developed for the Indian AEW&C system to surmount these unusual constraints.Defence Science Journal, 2013, 63(2, pp.138-144, DOI:http://dx.doi.org/10.14429/dsj.63.4255

    It is worth distinguishing between the two strategies of expectant management for prostate cancer. Watchful waiting entails administering non-curative androgen deprivation therapy to patients on development of symptomatic progression, whereas active surveillance entails delivering curative treatment on signs of disease progression. The objectives of the two management strategies and the patients enrolled in either are different: (i) to review the role of active surveillance as a management strategy for patients with low-risk prostate cancer; and (ii) review the benefits and pitfalls of active surveillance. We carried out a systematic review of active surveillance for prostate cancer in the literature using the National Center for Biotechnology Information's electronic database, PubMed. We carried out a search in English using the terms: active surveillance, prostate cancer, watchful waiting and conservative management. Selected studies were required to have a comprehensive description of the demographic and disease characteristics of the patients at the time of diagnosis, inclusion criteria for surveillance, and a protocol for the patients' follow up. Review articles were included, but not multiple papers from the same datasets. Active surveillance appears to reduce overtreatment in patients with low-risk prostate cancer without compromising cancer-specific survival at 10 years. Therefore, active surveillance is an option for select patients who want to avoid the side-effects inherent to the different types of immediate treatment. However, inclusion criteria for active surveillance and the most appropriate method of monitoring patients on active surveillance have not yet been standardized. PMID:26621054

  11. Secure Video Surveillance System (SVSS) for unannounced safeguards inspections

    International Nuclear Information System (INIS)

    The Secure Video Surveillance System (SVSS) is a collaborative effort between the U.S. Department of Energy (DOE), Sandia National Laboratories (SNL), and the Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC). The joint project addresses specific requirements of redundant surveillance systems installed in two South American nuclear facilities as a tool to support unannounced inspections conducted by ABACC and the International Atomic Energy Agency (IAEA). The surveillance covers the critical time (as much as a few hours) between the notification of an inspection and the access of inspectors to the location in facility where surveillance equipment is installed. ABACC and the IAEA currently use the EURATOM Multiple Optical Surveillance System (EMOSS). This outdated system is no longer available or supported by the manufacturer. The current EMOSS system has met the project objective; however, the lack of available replacement parts and system support has made this system unsustainable and has increased the risk of an inoperable system. A new system that utilizes current technology and is maintainable is required to replace the aging EMOSS system. ABACC intends to replace one of the existing ABACC EMOSS systems by the Secure Video Surveillance System. SVSS utilizes commercial off-the shelf (COTS) technologies for all individual components. Sandia National Laboratories supported the system design for SVSS to meet Safeguards requirements, i.e. tamper indication, data authentication, etc. The SVSS consists of two video surveillance cameras linked securely to a data collection unit. The collection unit is capable of retaining historical surveillance data for at least three hours with picture intervals as short as 1sec. Images in .jpg format are available to inspectors using various software review tools. SNL has delivered two SVSS systems for test and evaluation at the ABACC Safeguards Laboratory.

    Pennington, D M

    2006-03-24

    Sonoma offers the first cost-effective, broad-area, high-resolution, real-time motion imagery system for surveillance applications. Sonoma is unique in its ability to provide continuous, real-time video imagery of an area the size of a small city with resolutions sufficient to track 8,000 moving objects in the field of view. At higher resolutions and over smaller areas, Sonoma can even track the movement of individual people. The visual impact of the data available from Sonoma is already causing a paradigm shift in the architecture and operation of other surveillance systems. Sonoma is expected to cost just one-tenth the price of comparably sized sensor systems. Cameras mounted on an airborne platform constantly monitor an area, feeding data to the ground for real-time analysis. Sonoma was designed to provide real-time data for actionable intelligence in situations such as monitoring traffic, special events, border security, and harbors. If a Sonoma system had been available in the aftermath of the Katrina and Rita hurricanes, emergency responders would have had real-time information on roads, water levels, and traffic conditions, perhaps saving many lives.

    Daniel M. Oppenheimer

    2009-08-01

    Full Text Available The gambler's fallacy (Tune, 1964 refers to the belief that a streak is more likely to end than chance would dictate. In three studies, participants exhibited a extit{retrospective gambler's fallacy} (RGF in which an event that seems rare appears to come from a longer sequence than an event that seems more common. Study 1 demonstrates this bias for streaks, while Study 2 does so with single rare events and shows that the appearance of rarity is more important than actual rarity. Study 3 extends these findings from abstract gambling domains into real world domains to demonstrate the generalizability of the effects. The RGF follows from the law of small numbers (Tversky and Kahneman, 1971 and has many applications, from perceptions of the social world to philosophical debates about the existence of multiple universes.

    Full Text Available BACKGROUND Ovarian tumours being second most common gynaecological cancer in India account for 30% of all cancers of female genital tract. Study conducted to determine relative frequencies of various histological types based on WHO classification and their age distribution with particular emphasis on surface epithelial tumours. This study is undertaken to find out the frequency of incidence of different histopathological subtypes with particular emphasis on surface epithelial tumours and age distribution of ovarian tumours in our institute located in coastal Andhra Pradesh. METHODS This is a retrospective study of 100 cases of ovarian neoplasms collected during a period of 3 years from June 2013 to May 2016 from the Department of Pathology, Katuri Medical College and Hospital, Chinakondrupadu, Guntur, A. P, India. The patients attending our hospital are mostly from rural areas around. Paraffin blocks of all 100 ovarian neoplasms retrieved. Complete clinical and radiological findings analysed from our records. RESULTS The tumours are grouped according to the nature of tumour whether benign or borderline or malignant according to cell of origin, histological subtyping, and age group. Surface epithelial tumours are the most common. Benign tumours outnumber the malignant tumours. Benign ovarian tumours showed a peak in 21-40 Yrs. age group and malignant in the age group of 41- 60 Yrs. Results of our study compared with other studies. CONCLUSION Because of the geographic location, poverty, and illiteracy, patients seek medical advice late. So, awareness among public by health education, passive surveillance, and community screening facility will be helpful in early detection of ovarian neoplasms.

    An effective public safety sensor system for heavily-populated applications requires sophisticated and geographically-distributed infrastructures, centralized supervision, and deployment of large-scale security and surveillance networks. Artificial intelligence in sensor systems is a critical design to raise awareness levels, improve the performance of the system and adapt to a changing scenario and environment. In this paper, a highly-distributed, fault-tolerant, and energy-efficient Smart Sensing Surveillance System (S4) is presented to efficiently provide a 24/7 and all weather security operation in crowded environments or restricted areas. Technically, the S4 consists of a number of distributed sensor nodes integrated with specific passive sensors to rapidly collect, process, and disseminate heterogeneous sensor data from near omni-directions. These distributed sensor nodes can cooperatively work to send immediate security information when new objects appear. When the new objects are detected, the S4 will smartly select the available node with a Pan- Tilt- Zoom- (PTZ) Electro-Optics EO/IR camera to track the objects and capture associated imagery. The S4 provides applicable advanced on-board digital image processing capabilities to detect and track the specific objects. The imaging detection operations include unattended object detection, human feature and behavior detection, and configurable alert triggers, etc. Other imaging processes can be updated to meet specific requirements and operations. In the S4, all the sensor nodes are connected with a robust, reconfigurable, LPI/LPD (Low Probability of Intercept/ Low Probability of Detect) wireless mesh network using Ultra-wide band (UWB) RF technology. This UWB RF technology can provide an ad-hoc, secure mesh network and capability to relay network information, communicate and pass situational awareness and messages. The Service Oriented Architecture of S4 enables remote applications to interact with the S4

    Unattended ground sensor (UGS) networks have been widely used in remote battlefield and other tactical applications over the last few decades due to the advances of the digital signal processing. The UGS network can be applied in a variety of areas including border surveillance, special force operations, perimeter and building protection, target acquisition, situational awareness, and force protection. In this paper, a highly-distributed, fault-tolerant, and energyefficient Smart Sensing Surveillance System (S4) is presented to efficiently provide 24/7 and all weather security operation in a situation management environment. The S4 is composed of a number of distributed nodes to collect, process, and disseminate heterogeneous sensor data. Nearly all S4 nodes have passive sensors to provide rapid omnidirectional detection. In addition, Pan- Tilt- Zoom- (PTZ) Electro-Optics EO/IR cameras are integrated to selected nodes to track the objects and capture associated imagery. These S4 camera-connected nodes will provide applicable advanced on-board digital image processing capabilities to detect and track the specific objects. The imaging detection operations include unattended object detection, human feature and behavior detection, and configurable alert triggers, etc. In the S4, all the nodes are connected with a robust, reconfigurable, LPI/LPD (Low Probability of Intercept/ Low Probability of Detect) wireless mesh network using Ultra-wide band (UWB) RF technology, which can provide an ad-hoc, secure mesh network and capability to relay network information, communicate and pass situational awareness and messages. The S4 utilizes a Service Oriented Architecture such that remote applications can interact with the S4 network and use the specific presentation methods. The S4 capabilities and technologies have great potential for both military and civilian applications, enabling highly effective security support tools for improving surveillance activities in densely crowded

  2. Drug approval and surveillance.

    This article argues that current regulations governing the licensing of drugs, particularly in the U.S., need to be changed and replaced by a system of provisional or conditional licensing and increased postmarketing surveillance of drug use. In terms of research and development of new forms of contraception, this proposal would have great impact. It is believed that the U.S./Food and Drug Administration (FDA) requirements--animal experiments and Phase 1 and 2 clinical trials--not only put an unacceptable financial burden on any institution attempting to develop new contraceptives, but do not demonstrably contribute to the reduction of risks. The author questions whether even if oral contraceptives introduced prior to new U.S./FDA regulations had been subject to these current regulations that convincing evidence would have been found to alert anyone to the now-known rare adverse effects, such as risk of thromboembolism. It is pointed out that these sorts of rare risks were uncovered by continuous screening processes which are not now a part of the FDA drug regulation requirements. The author also questions the politics of "conpulsory safety," such as might be legislated for regulated car safety belt use. Citing a partnership already established between government and private industry in high-risk/low cost ventures in the aerospace industry, the author sees no reason why such a relationship could not evolve in the pharmaceutical industry. In Britain, proposals have been made to establish a fund to compensate patients adversely affected by drugs which pharmaceutical companies would reimburse if proved negligent; such a fund may work in the U.S. under new regulations which stress postmarketing surveillance.

    Results from the 9975 shipping package Storage and Surveillance Program at the Savannah River Site (SRS) are summarized for justification to extend the life of the 9975 packages currently stored in the K-Area Complex (KAC). This justification is established with the stipulation that surveillance activities will continue throughout the extended time to ensure the continued integrity of the 9975 materials of construction and to further understand the currently identified degradation mechanisms. The 10 year storage life justification was developed prior to storage. A subsequent report was later used to validate the qualification of the 9975 shipping packages for 10 years in storage. However the qualification for the storage period was provided by the monitoring requirements of the 9975 Storage and Surveillance Program. This report summarizes efforts to determine a new safe storage limit for the 9975 shipping package based on the surveillance data collected since 2005 when the 9975 Storage and Surveillance Program began. The Program has demonstrated that the 9975 package has a robust design that can perform under a variety of conditions. The primary emphasis of the on-going 9975 Storage and Surveillance Program is an aging study of the 9975 Viton{reg_sign} containment vessel O-rings and the Celotex{reg_sign} fiberboard thermal insulation at bounding conditions of radiation, elevated temperatures and/or elevated humidity.

    OBJECTIVE Pilocytic astrocytomas (PAs) are common brain tumors in children. Optimal management of PA is gross-total resection (GTR), after which event-free survival (EFS) is excellent. The tempo of recurrences, when they do occur, is relatively sparsely reported, and there is no agreed upon surveillance recommendation for patients in this category. It has been suggested that surveillance MRI is performed too frequently and could be safely reduced in both frequency and duration. The authors conducted a retrospective review of pediatric patients with PA who underwent GTR at a single institution over an 18-year period and who had documented recurrences. METHODS All patients under 18 years of age who had undergone GTR of a PA between 1996 and 2013 were included in the study. Clinical, radiological, and tumor characteristics were recorded. RESULTS Sixty-seven patients met the criteria for GTR over the period studied. The 5-year EFS rate was 95% (95% CI 89%-100%) and overall survival was 100%. Recurrences showed a nonsignificant trend of occurring more commonly in patients with persistent nonenhancing FLAIR abnormalities after surgery, but there was no difference with regard to tumor location. All recurrences occurred before 3 years postresection, all were asymptomatic, and all patients were observed for at least one additional scan after the initial detection during routine surveillance MRI before further therapy was undertaken. CONCLUSIONS EFS and overall survival are excellent after GTR in this population with PAs. Progression after recurrence occurs slowly and is asymptomatic. A less intensive schedule of MRI surveillance in this group of patients would result in time and cost savings, without compromising safety. The authors suggest a schedule of 6 MRI scans to be obtained postoperatively, at 3-6 months, then at 1, 2, 3.5, and 5 years. PMID:26722760

    The purpose of the present study was to retrospectively evaluate the clinical findings and treatment results for impacted permanent teeth associated with odontomas. We retrospectively investigated 73 odontomas in 72 patients who visited Kyungpook National University Dental Hospital from April 2004 through November 2011. The study was performed using medical records, panoramic radiographs, and pathological reports. Data gathered included age, gender, location, chief complaints, effects on dentition, and treatment of odontoma and the impacted tooth associated with odontoma. Most compound odontomas (46.7%) were found in the second decade and complex odontomas were not related to age. Odontomas showed no gender predilection. Fifty-five cases (75.3%) of odontomas were detected on routine dental radiographs. Sixty percent of compound odontomas occurred in the canine area and 57.1% of complex odontomas in the molar areas. Impaction of permanent teeth (61.6%) was the most common complication on the adjacent teeth. Most odontomas (84.9%) were removed surgically and impacted permanent teeth were managed by surgical removal (53.2%), orthodontic treatment (25.5%), or surgical repositioning (6.4%). There was a statistically significant relation between age and preservation of the impacted permanent teeth associated with odontomas (p<0.01). Early detection and treatment of odontomas increase the possibility of preservation of the impacted tooth. Therefore, it would be suggested that periodic panoramic examination during the first and second decade of life might be beneficial for the early detection and better prognosis of odontomas.

    In an effort to recognize and address communicable and point-source epidemics in dog and cat populations, this project created a near real-time syndromic surveillance system devoted to companion animal health in the United States. With over 150 million owned pets in the US, the development of such a system is timely in light of previous epidemics due to various causes that were only recognized in retrospect. The goal of this study was to develop epidemiologic and statistical methods for veterinary hospital-based surveillance, and to demonstrate its efficacy by detection of simulated foodborne outbreaks using a database of over 700 hospitals. Data transfer protocols were established via a secure file transfer protocol site, and a data repository was constructed predominantly utilizing open-source software. The daily proportion of patients with a given clinical or laboratory finding was contrasted with an equivalent average proportion from a historical comparison period, allowing construction of the proportionate diagnostic outcome ratio and its confidence interval for recognizing aberrant heath events. A five-tiered alert system was used to facilitate daily assessment of almost 2,000 statistical analyses. Two simulated outbreak scenarios were created by independent experts, blinded to study investigators, and embedded in the 2010 medical records. Both outbreaks were detected almost immediately by the alert system, accurately detecting species affected using relevant clinical and laboratory findings, and ages involved. Besides demonstrating proof-in-concept of using veterinary hospital databases to detect aberrant events in space and time, this research can be extended to conducting post-detection etiologic investigations utilizing exposure information in the medical record.

  11. Total process surveillance (TOPS)

    International Nuclear Information System (INIS)

    Understanding the current operating behaviour of a process or power plant is the key to maximizing the efficiency and safety of operation and the quality of the product. Early detection of plant component or sensor degradation and failure improves operating safety, product quality and plant availability. This paper describes the design and development of a Total Process Surveillance system which assimilates all the sensor information available on a plant to provide the operators with a succinct report on the status of the plant behaviour. The heart of the system is a robust model-based observer which can estimate internal plant states, and provides a residual signal with powerful fault detection and isolation features. Several results are presented which illustrate the performance of the system in detecting and isolating multiple fault scenarios in a fast reactor plant. A structure for the practical implementation of the system is described, and comments are given on its contribution to the final experimental work planned for AEA Technology's Prototype Fast Reactor (PFR).

    Abstract Constant malaria monitoring and surveillance systems have been highlighted as critical for malaria elimination. The absence of robust monitoring and surveillance systems able to respond to outbreaks in a timely manner undeniably contributed to the failure of the last global attempt to eradicate malaria. Today, technological advances could allow for rapid detection of focal outbreaks and improved deployment of diagnostic and treatment supplies to areas needing support. However, optimi...

    IMF surveillance of the international monetary and financial system is a global public good. Its effectiveness depends critically on the dynamics that underpin the mechanisms governing the IMF and global finance. These dynamics, in turn, reflect the interests and power of influence of countries (especially the largest), their cooperative attitude and international relations. Assessing the effectiveness of IMF surveillance, therefore, demands a clear understanding of the IMF and global financi...

    Scabies outbreaks can be disruptive in institutional settings, and are associated with considerable but under-researched morbidity, especially in vulnerable populations. In this paper, we describe key findings from a retrospective review of scabies outbreaks reported in the literature over the past 30 years. We undertook this review to gain insights into the impact of institutional outbreaks, the burden in terms of attack rates, economic costs, treatment trends, the types of index cases and outbreak progression. We found 84 reports over 30 years, with outbreaks most frequently reported in aged care facilities (n = 40) and hospitals (n = 33). On average, scabies outbreaks persisted for 3 months, and the median attack rate was 38%. While 1% lindane was once the most commonly employed acaricide, 5% permethrin and oral ivermectin are increasingly used. Crusted scabies represented the index case for 83% of outbreaks, and scabies was misdiagnosed in 43% outbreaks. The frequency of reported scabies outbreaks has not declined consistently over time suggesting the disease is still highly problematic. We contend that more research and practice emphasis must be paid to improve diagnostic methods, surveillance and control, health staff education and management of crusted scabies to prevent the development of scabies outbreaks in institutional settings.

    The RA10 is a new 30 Mw research reactor which is in the design stage. The surveillance program, as part of the Ageing Management Program, is needed to confirm and determine the effects of radiation on the mechanical properties of the core reactor materials, Zircaloy-4, Stainless Steels and Aluminum Alloys. Effects of interest are tensile properties, ductility does not reduce significantly, fracture toughness to prevent propagation of a crack of a certain size and radiation-induced growth. Surveillance capsules will be placed in three locations in RA10 reactor. The capsules are placed in regions were the flux is higher than the component they represent.

  20. LTO and surveillance specimen programme of RPV

    International Nuclear Information System (INIS)

    Plant life extension (as well as Long Term Operation) to 60 or 80 years of operation also requires a reliable information about the potential irradiation embrittlement (and also thermal ageing) of reactor pressure vessel materials. Such information is usually obtained from testing specimens within the surveillance specimen programme that is designed for the design RPV life, regularly for 40 years only. Life extension requires modification of such programme (if there is still time to perform it) or a design of a new extended one. Such programme should have to contain RPV archive materials that are not in every case available. Thus, combination of archive materials and possible surrogate materials must be taken into account for this programme. Some complication can be expected with thermal ageing data as some laboratory tests at higher temperatures must be realized. The paper describes such program for NPP Dukovany, Czech Republic with WWER-440 type reactors. (authors)

    Although eradicated in Portugal, malaria keeps taking its toll on travellers and migrants from endemic countries. Completeness of hospital requiring malaria notification in Portugal 2000-11 was estimated, using two-source capture-recapture method. Data sources were: national surveillance database of notifiable diseases and the national database of the Diagnosis-Related Groups resulting from National Health Service (NHS) hospital episodes. The completeness of notification was 21,2% for all malaria cases and 26,5% for malaria deaths, indicating significant underreporting and urging for complementary data source in surveillance, for disease burden estimates and retrospective monitoring, namely hospital episodes statistics.

  2. Ageing management

    International Nuclear Information System (INIS)

    Ageing management is generally defined in a broad sense covering not only ageing management of hardware (structures, systems and components), but also management issues such as keeping up with developments in state-of-the-art technology and the latest management practices. The importance assigned to traditional ageing management, in terms of issues related to hardware degradation problems, is clearly very high. The other aspects, for example developments in engineering or management, are considered important as well, but are less emphasized. Plant ageing management is composed of the following necessary elements, which are all linked together: understanding and knowledge of ageing-related damage mechanisms, including benchmarking of the consequences of damage mechanisms into macroscopic behaviour of materials and structures under applicable conditions; predictive models to extrapolate behaviour of systems, structures or components up to a defined time; qualified methods for detection and surveillance of ageing degradation; qualified mitigation, repair and replacements measures; reliable plant documentation, including optimisation of the ageing management programme based on current understanding and knowledge and periodic self-assessment; availability of a technical service and knowledge base. The subject of plant ageing management has gained increasing attention over the past years, notably as more nuclear power plants across the world are being considered for lifetime extension. In this context, the NEA has conducted numerous technical studies to assess the impact of ageing mechanisms on safe and reliable plant operation. International research activities have also been initiated or are under way to provide the technical basis for decision making. This article provides an overview of some of the activities and accomplishments of the NEA Committee on the Safety of Nuclear Installations (CSNI) Working Group on the Integrity and Ageing of Components and Structures

    An Acute Flaccid Paralysis (AFP) surveillance system was set up in Lombardy (Northern Italy) in 1997 in the framework of the national AFP surveillance system, as part of the polio eradication initiative by the World Health Organization (WHO). This surveillance system can now be used to detect Poliovirus (PV) reintroductions from endemic countries. This study aimed at describing the results of the AFP surveillance in Lombardy, from 1997 to 2011.   Overall, 131 AFP cases in Lombardy were reported with a mean annual incidence rate of 0.7/100 000 children <15 years of age (range: 0.3/100 000-1.1/100 000). The sensitivity of the surveillance system was optimal from 2001-2003. The monthly distribution of AFP cases was typical with peaks in November, in January, and in March. The major clinical diagnoses associated with AFP were Guillain-Barré Syndrome (GBS, 40%) and encephalomyelitis/myelitis (13%). According to the virological results, no poliomyelitis cases were caused by wild PV infections, but two Vaccine-Associated Paralytic Paralysis (VAPP) cases were reported in 1997 when the Sabin oral polio vaccine (OPV) was still being administered in Italy. Since a surveillance system is deemed sensitive if at least one case of AFP per 100,000 children <15 years of age is detected each year, our surveillance system needs some improvement and must be maintained until global poliovirus eradication will be declared.

    2009-01-01

    Patients with inflammatory bowel disease (IBD) are at increased risk for colorectal cancer (CRC). Risk factors for the development of CRC in the setting of IBD include disease duration, anatomic extent of disease,age at time of diagnosis, severity of inflammation,family history of colon cancer, and concomitant primary sclerosing cholangitis. The current surveillance strategy of surveillance colonoscopy with multiple random biopsies most likely reduces morbidity and mortality associated with IBD-related CRC. Unfortunately,surveillance colonoscopy also has severe limitations including high cost, sampling error at time of biopsy,and interobserver disagreement in histologically grading dysplasia. Furthermore, once dysplasia is detected there is disagreement about its management.Advances in endoscopic imaging techniques are already underway, and may potentially aid in dysplasia detection and improve overall surveillance outcomes.Management of dysplasia depends predominantly on the degree and focality of dysplasia, with the mainstay of management involving either proctocolectomy or continued colonoscopic surveillance. Lastly, continued research into additional chemopreventive agents may increase our arsenal in attempting to reduce the incidence of IBD-associated CRC.

    Full Text Available Congenital syphilis (CS is mainly a consequence of the lack of antenatal care and control of sexually transmitted infections.The bedrock of the prevention of CS is syphilis diagnosis by serological screening during pregnancy.Current Italian guidelines suggest that all the pregnant women should be tested in the first trimester. Due to the frequently absence of specific signs of infection at birth, laboratory tests are often the only method for a correct CS diagnosis. The aim of this study was to evaluate the usefulness of Treponema pallidum IgM Western Blot (WB and Polymerase Chain Reaction (PCR on cerebrospinal fluid (CSF as an aid in the diagnosis of CS during a prospective surveillance study carried out at St. Orsola Hospital in Bologna, Italy, from November 2000 through June 2010. All pregnant women during pregnancy and at delivery were screened for syphilis by ARCHITECT® Syphilis TP, Abbott. Positive samples were further analysed by Treponema Pallidum Hemagglutination Test (TPHA and Rapid Plasma Reagin (RPR tests, Radim.An in-house Western Blot (WB was also performed. Infants born to syphilis seropositive mothers were enrolled in a prospective follow up. At birth, tests were performed (including IgM WB. Infants with positive RPR tests at birth born to mothers not adequately treated received also a long bone radiograph as well as a complete CSF analysis, including Veneral Disease Research Laboratori (VDRL (Siemens Healthcare Diagnostics and PCR testing. All seroreactive infants received careful follow up examinations and serological testing at 0, 3, 6, 9, 12 months or until the tests became negative. In this study, positive syphilis serology was noted in 151 pregnant women delivering in our hospital. Fifteen women had never been adequately treated, and 9 out 15 gave birth to infected newborns.All these 9 infants had positive IgM WB results on serum samples. Two babies had characteristic long bone lesions at X-ray examination and 3 were born

  7. Project Surveillance and Maintenance Plan

    The Project Surveillance and Maintenance Plan (PSMP) describes the procedures that will be used by the US Department of Energy (DOE), or other agency as designated by the President to verify that inactive uranium tailings disposal facilities remain in compliance with licensing requirements and US Environmental Protection Agency (EPA) standards for remedial actions. The PSMP will be used as a guide for the development of individual Site Surveillance and Maintenance Plans (part of a license application) for each of the UMTRA Project sites. The PSMP is not intended to provide minimum requirements but rather to provide guidance in the selection of surveillance measures. For example, the plan acknowledges that ground-water monitoring may or may not be required and provides the [guidance] to make this decision. The Site Surveillance and Maintenance Plans (SSMPs) will form the basis for the licensing of the long-term surveillance and maintenance of each UMTRA Project site by the NRC. Therefore, the PSMP is a key milestone in the licensing process of all UMTRA Project sites. The Project Licensing Plan (DOE, 1984a) describes the licensing process. 11 refs., 22 figs., 8 tabs

    The potential impact of breast cancer-related lymphedema (LE) is quite extensive, yet it often remains under-diagnosed until the later stages. This project examines the effectiveness of prospective surveillance in post-surgical breast cancer patients. A retrospective analysis of 49 out of 100 patients enrolled in a longitudinal prospective study at a Midwestern breast center evaluates: (1) time required for completion of bilateral limb measurements and Lymphedema Breast Cancer Questionnaire (LBCQ); (2) referral to LE management with limb volume increase (LVI) and/or LBCQ symptoms; and (3) cost of LE management at lower LVI (≥5%-≤10%) versus traditional (≥10%). Findings revealed a visit timeframe mean of 40.3 min (range = 25-60); 43.6% of visits were ≤30-min timeframe. Visit and measurement times decreased as clinic staff gained measurement experience; measurement time mean was 17.9 min (range = 16.9-18.9). LBCQ symptoms and LVI were significantly (p < 0.001) correlated to LE referral; six of the nine patients referred (67%) displayed both LBCQ symptoms/LVI. Visits with no symptoms reported did not result in referral, demonstrating the importance of using both indicators when assessing early LE. Lower threshold referral provides compelling evidence of potential cost savings over traditional threshold referral with reported costs of: $3755.00 and $6353.00, respectively (40.9% savings).

  16. Total Process Surveillance (TOPS)

    International Nuclear Information System (INIS)

    analytical redundancy is of significant importance in order to obtain the maximum amount of information as to the state of the plant. A further logical step in this theory is the accommodation of failed or damaged transducers by deriving their measurement information from the available remaining transducers. A system capable of providing a clear and improved picture of the plant's behaviour under a range of normal and off-normal operating conditions would thus be of significant economical and safety benefit. In summary: A Total Process Surveillance system is under development which can provide, in real-time, additional process information from a limited number of raw measurement signals. This is achieved by using a robust model based observer to generate estimates of the process' internal states. The observer utilises the analytical redundancy among a diverse range of transducers and can thus accommodate off-normal conditions which lead to transducer loss or damage. The modular hierarchical structure of the system enables the maximum amount of information to be assimilated from the available instrument signals no matter how diverse. This structure also constitutes a data reduction path thus reducing operator cognitive overload from a large number of varying, and possibly contradictory, raw plant signals. The TOPS system provides a structured and complete means for plant data management under both normal and off-normal operating conditions and thus will significantly assist the operator during severe accident management

    Tilston, Natasha; Skelly, Chris; Weinstein, Phil

    2009-01-01

    The first documented transmission of Chikungunya within Europe took place in Italy during the summer of 2007. Chikungunya, a viral infection affecting millions of people across Africa and Asia, can be debilitating and no prophylactic treatment exists. Although imported cases are reported frequently across Europe, 2007 was the first confirmed European outbreak and available evidence suggests that Aedes albopictus was the vector responsible and the index case was a visitor from India. This paper proposed pan-European surveillance zones for Chikungunya, based on the climatic conditions necessary for vector activity and viral transmission. Pan-European surveillance provides the best hope for an early-warning of outbreaks, because national boundaries do not play a role in defining the risk of this new vector borne disease threat. A review of climates, where Chikungunya has been active, was used to inform the delineation of three pan-European surveillance zones. These vary in size each month across the June-September period of greatest risk. The zones stretch across southern Europe from Portugal to Turkey. Although the focus of this study was to define the geography of potential surveillance zones based on the climatic limits on the vector and virus, a preliminary examination of inward bound airline passengers was also undertaken. This indicated that France and Italy are likely to be at greater risk due to the number of visitors they receive from Chikungunya active regions, principally viraemic visitors from India. Therefore this study represents a first attempt at creating risk stratified surveillance zones, which we believe could be usefully refined with the use of higher resolution climate data and more complete air travel data.

    LENUS (Irish Health Repository)

    Keane, R A

    2011-11-15

    Colonoscopic surveillance of hyperplastic polyps alone is controversial and may be inappropriate. The colonoscopy surveillance register at a university teaching hospital was audited to determine the extent of such hyperplastic polyp surveillance. The surveillance endoscopy records were reviewed, those patients with hyperplastic polyps were identified, their clinical records were examined and contact was made with each patient. Of the 483 patients undergoing surveillance for colonic polyps 113 (23%) had hyperplastic polyps alone on last colonoscopy. 104 patients remained after exclusion of those under appropriate surveillance. 87 of the 104 patients (84%) were successfully contacted. 37 patients (8%) were under appropriate colonoscopic surveillance for a significant family history of colorectal carcinoma. 50 (10%) patients with hyperplastic polyps alone and no other clinical indication for colonoscopic surveillance were booked for follow up colonoscopy. This represents not only a budgetary but more importantly a clinical opportunity cost the removal of which could liberate valuable colonoscopy time for more appropriate indications.

    On June 1, 2006, public health officials working in surveillance, epidemiological modeling, and information technology communities from the Seattle/Tacoma area and State of Washington met with members of the Pacific Northwest National Laboratory (PNNL) to discuss the current state of disease surveillance and gaps and needs to improve the current systems. The meeting also included a discussion of PNNL initiatives that might be appropriate to enhance disease surveillance and the current tools being used for disease surveillance. Participants broke out into two groups to identify critical gaps and needs for improving a surveillance system, and discuss the requirements for developing improved surveillance. Each group developed a list of key priorities summarizing the requirements for improved surveillance. The objective of this meeting was to work towards the development of an improved disease surveillance system.

  6. Surveillance considerations for malaria elimination

    Directory of Open Access Journals (Sweden)

    Barclay Victoria C

    2012-08-01

    Full Text Available Abstract Constant malaria monitoring and surveillance systems have been highlighted as critical for malaria elimination. The absence of robust monitoring and surveillance systems able to respond to outbreaks in a timely manner undeniably contributed to the failure of the last global attempt to eradicate malaria. Today, technological advances could allow for rapid detection of focal outbreaks and improved deployment of diagnostic and treatment supplies to areas needing support. However, optimizing diffusion activities (e.g., distributing vector controls and medicines, as well as deploying behaviour change campaigns requires networks of diverse scholars to monitor, learn, and evaluate data and multiple organizations to coordinate their intervention activities. Surveillance systems that can gather, store and process information, from communities to national levels, in a centralized, widely accessible system will allow tailoring of surveillance and intervention efforts. Different systems and, thus reactions, will be effective in different endemic, geographical or socio-cultural contexts. Investing in carefully designed monitoring technologies, built for a multiple-acter, dynamic system, will help to improve malaria elimination efforts by improving the coordination, timing, coverage, and deployment of malaria technologies.

    A surveillance system looks through the atmosphere along a horizontal or slant path. Turbulence along the path causes blurring. The blurring is corrected by speckle processing short exposure images recorded with a camera. The exposures are short enough to effectively freeze the atmospheric turbulence. Speckle processing is used to recover a better quality image of the scene.

    Forms of surveillance are very quickly becoming an integral part of crime control policy, crisis management, social control theory and community consciousness. In turn, it has been used as a simple and effective solution to many of these problems. However, privacy-related concerns have been expressed over the development and deployment of this technology. Used properly, video cameras help expose wrongdoing but typically come at the cost of privacy to those not involved in any maleficent activity. This work describes the design and implementation of a real-time, privacy-protecting video surveillance infrastructure that fuses additional sensor information (e.g. Radio-frequency Identification) with video streams and an access control framework in order to make decisions about how and when to display the individuals under surveillance. This video surveillance system is a particular instance of a more general paradigm of privacy-protecting data collection. In this paper we describe in detail the video processing techniques used in order to achieve real-time tracking of users in pervasive spaces while utilizing the additional sensor data provided by various instrumented sensors. In particular, we discuss background modeling techniques, object tracking and implementation techniques that pertain to the overall development of this system.

  9. Invasive neuroendocrine carcinoma of the breast: a population-based study from the surveillance, epidemiology and end results (SEER) database

    International Nuclear Information System (INIS)

    Neuroendocrine carcinoma (NEC) of the breast is a rare type of carcinoma that has not been well studied or characterized. Of the limited number of studies reported in the literature, most are case reports. A few small retrospective series studies have been reported. We reviewed data on 142 cases of mammary NEC recorded in the surveillance, epidemiology, and end results (SEER) database during 2003–2009 and evaluated disease incidence and patient age, sex, and race/ethnicity; clinicopathologic characteristics; and survival in comparison to invasive mammary carcinoma, not otherwise specified. We also performed univariate and multivariate analyses to identify prognostic factors in this disease. Review of the 142 SEER cases revealed that NEC is an aggressive variant of invasive mammary carcinoma. It generally occurred in older women (>60 years); present with larger tumor size (>20 mm), higher histologic grade, and higher clinical stage; and result in shorter overall survival and disease-specific survival than invasive mammary carcinoma, not otherwise specified (IMC-NOS). Overall survival and disease-specific survival were shorter in NEC at each stage than in IMC-NOS of the same stage. Furthermore, when all NEC and IMC-NOS cases were pooled together, neuroendocrine differentiation itself was an adverse prognostic factor independent of other known prognostic factors, including age, tumor size, nodal status, histologic grade, estrogen/progesterone receptor status, and therapy. NEC is a rare but aggressive type of mammary carcinoma. Novel therapeutic approaches should be explored for this uniquely clinical entity

    2008-12-01

    Full Text Available PURPOSE: The optimal management of patients with clinical stage I non-seminomatous germ cell testicular cancer (NSGCT I was considered controversial until the European Germ Cell Cancer Consensus Group determined unambiguous treatment strategies. In order to assess the long-term outcome we evaluated the data of patients with NSGCT I. MATERIALS AND METHODS: In a retrospective evaluation, we included 52 patients with a mean age of 26 years (range 15-58 who were treated with different modalities at our department between 1989 and 2003. Mean follow-up was 5.9 years (range 2-14 years. After orchiectomy, 39 patients were treated with chemotherapy, 7 patients underwent retroperitoneal lymph node dissection and 6 men were managed using a surveillance strategy. Survival, recurrence rate and time of recurrence were evaluated. The histological staging and treatment modality was related to the relapse. RESULTS: Tumor specific overall mortality was 3.8%. The mortality and relapse rate of the surveillance strategy, retroperitoneal lymph node dissection and chemotherapy was 16.7% / 50%, 14.3% / 14.3% and 0% / 2.5% respectively. All relapsed patients in the surveillance group as well as in the RPLND group had at least one risk factor for developing metastatic disease. CONCLUSIONS: Following the European consensus on diagnosis and treatment of germ cell cancer in patients with NSGCT Stage I any treatment decision must be individually related to the patient according to prognostic factors and care capacity of the treating centre. In case of doubt, adjuvant chemotherapy should be the treatment of choice, as it provides the lowest risk of relapse or tumor related death.

  11. Environmental surveillance master sampling schedule

    International Nuclear Information System (INIS)

    Environmental surveillance of the Hanford Site and surrounding areas is conducted by the Pacific Northwest Laboratory (PNL) for the U.S. Department of Energy (DOE). This document contains the planned 1994 schedules for routine collection of samples for the Surface Environmental Surveillance Project (SESP), Drinking Water Project, and Ground-Water Surveillance Project. Samples are routinely collected for the SESP and analyzed to determine the quality of air, surface water, soil, sediment, wildlife, vegetation, foodstuffs, and farm products at Hanford Site and surrounding communities. The responsibility for monitoring onsite drinking water falls outside the scope of the SESP. PNL conducts the drinking water monitoring project concurrent with the SESP to promote efficiency and consistency, utilize expertise developed over the years, and reduce costs associated with management, procedure development, data management, quality control, and reporting. The ground-water sampling schedule identifies ground-water sampling .events used by PNL for environmental surveillance of the Hanford Site. Sampling is indicated as annual, semi-annual, quarterly, or monthly in the sampling schedule. Some samples are collected and analyzed as part of ground-water monitoring and characterization programs at Hanford (e.g. Resources Conservation and Recovery Act (RCRA), Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), or Operational). The number of samples planned by other programs are identified in the sampling schedule by a number in the analysis column and a project designation in the Cosample column. Well sampling events may be merged to avoid redundancy in cases where sampling is planned by both-environmental surveillance and another program

    The Packaging Surveillance Program section of the DOE M441.1-1/sup>1, Nuclear Material Packaging Manual (DOE, 2008) requires DOE contractors to “ensure that a surveillance program is established and implemented to ensure the nuclear material storage package continues to meet its design criteria.” In order to ensure continuing safe storage of nuclear material and the maximization of risk reduction, TA-55 has established a Surveillance Program to ensure storage container integrity for operations within its specified design life. The LANL SAVY-4000 Field Surveillance Plan2 defines the near-term field surveillance plan for SAVY-4000 containers as required by the Manual. A long-term surveillance plan will be established based on the results of the first several years of surveillance and the results of the lifetime extension studies as defined in the Accelerated Aging Plan3. This report details progress in positioning the Surveillance Program for successful implementation in FY14 and status of the Design Life Extension Program in terms of its implementation and data collection for FY13.

  13. Estimation of the incidence of MRSA patients: evaluation of a surveillance system using health insurance claim data.

    Tanihara, S; Suzuki, S

    2016-08-01

    Because sentinel surveillance systems cannot obtain information about patients who visit non-sentinel medical facilities, the characteristics of patients identified by these systems may be biased. In this study, we evaluated the representativeness of a methicillin-resistant Staphylococcus aureus (MRSA) surveillance system using health insurance claim (HIC) data, which does not depend on physician notification. We calculated the age-specific incidence of MRSA patients using data from the Japan Nosocomial Infections Surveillance (JANIS) programme, which is based on sentinel surveillance systems, and inpatient HICs submitted to employee health insurance organizations in 2011, and then computed age-specific incidence ratios between the HIC and JANIS data. Age-specific MRSA incidence in both datasets followed J-shaped curves with similar shapes. For all age groups, the ratios between HIC and JANIS data were around 10. These findings indicate that JANIS notification of MRSA cases was not affected by patients' age. PMID:27350233

  15. Performance of 18F-FDG PET/CT as a postoperative surveillance imaging modality for asymptomatic advanced gastric cancer patients

    International Nuclear Information System (INIS)

    The purpose of this study was to investigate the diagnostic performance of postoperative fluorine-18 fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) as a surveillance modality for advanced gastric cancer patients who were asymptomatic and negative by conventional follow-up. We retrospectively collected 46 advanced gastric cancer patients who received approximately 1-year-postoperative 18F-FDG PET/CT surveillance following curative resection (mean age 60.6 ± 11.5 years). 18F-FDG PET/CT was interpreted by nuclear medicine physicians who were blind to the clinical information. Final confirmation was determined by clinical follow-up using tumor markers, conventional CT scan, upper gastrointestinal endoscopy and with/without subsequent histopathologic diagnosis. Four patients developed recurrence (8.7%; 1 local and 3 distant recurrences). For local recurrence, 18F-FDG PET/CT found four hypermetabolic lesions and one was local recurrence. For distant recurrence, seven hypermetabolic lesions were found in six patients and true-positive was three lesions. False-positive cases were mainly turned out to be physiologic small bowel uptake. Regardless of the recurrence site, the sensitivity, specificity, positive predictive value and negative predictive value of 18F-FDG PET/CT were 100% (4/4, 95% confidence interval (CI) 39.6-100%), 88.1% (37/42, 95% CI 73.6-95.5%), 44.4% (4/9, 95% CI 15.3-77.3%) and 100% (37/37, 95% CI 88.3-100%), respectively in the patient-based analysis. Our study showed good specificity of postoperative surveillance 18F-FDG PET/CT for detecting recurrence. Careful caution should be made for interpreting some false-positive hypermetabolic lesions in postoperative 18F-FDG PET/CT, especially at the local anastomosis site. (author)

    Full Text Available Abstract Background Following the outbreak of chikungunya in the Indian Ocean, the Ministry of Health directed the necessary development of an early outbreak detection system. A disease surveillance team including the Institut Pasteur in Madagascar (IPM was organized to establish a sentinel syndromic-based surveillance system. The system, which was set up in March 2007, transmits patient data on a daily basis from the various voluntary general practitioners throughout the six provinces of the country to the IPM. We describe the challenges and steps involved in developing a sentinel surveillance system and the well-timed information it provides for improving public health decision-making. Methods Surveillance was based on data collected from sentinel general practitioners (SGP. The SGPs report the sex, age, visit date and time, and symptoms of each new patient weekly, using forms addressed to the management team. However, the system is original in that SGPs also report data at least once a day, from Monday to Friday (number of fever cases, rapid test confirmed malaria, influenza, arboviral syndromes or diarrhoeal disease, by cellular telephone (encrypted message SMS. Information can also be validated by the management team, by mobile phone. This data transmission costs 120 ariary per day, less than US$1 per month. Results In 2008, the sentinel surveillance system included 13 health centers, and identified 5 outbreaks. Of the 218,849 visits to SGPs, 12.2% were related to fever syndromes. Of these 26,669 fever cases, 12.3% were related to Dengue-like fever, 11.1% to Influenza-like illness and 9.7% to malaria cases confirmed by a specific rapid diagnostic test. Conclusion The sentinel surveillance system represents the first nationwide real-time-like surveillance system ever established in Madagascar. Our findings should encourage other African countries to develop their own syndromic surveillance systems. Prompt detection of an outbreak of

  19. Public involvement in environmental surveillance at Hanford

    International Nuclear Information System (INIS)

    Environmental surveillance at the Hanford Site began during the mid-1940s following the construction and start-up of the nation's first plutonium production reactor. Over the past approximately 45 years, surveillance operations on and off the Site have continued, with virtually all sampling being conducted by Hanford Site workers. Recently, the US Department of Energy Richland Operations Office directed that public involvement in Hanford environmental surveillance operations be initiated. Accordingly, three special radiological air monitoring stations were constructed offsite, near hanford's perimeter. Each station is managed and operated by two local school teaches. These three stations are the beginning of a community-operated environmental surveillance program that will ultimately involve the public in most surveillance operations around the Site. The program was designed to stimulate interest in Hanford environmental surveillance operations, and to help the public better understand surveillance results. The program has also been used to enhance educational opportunities at local schools

  1. Health effects and medical surveillance

    International Nuclear Information System (INIS)

    Source of ionizing radiations have innumerable applications in the work place. Usually, even where the work is performed safely, the employees involved inevitably receive small, regular exposures to radiation that are not manifestly harmful. This Module explains how ionizing radiations can interact with and affect human tissues, the various factors that influence the outcome and the detrimental effects that may result. The medical surveillance that is appropriate for those working with radiation sources, depending on the degree of hazard of the work, is described. The Manual will be of most benefit it if forms part of more comprehensive training or is supplemented by the advice of a medically qualified expert. Where medical surveillance is appropriate for radiation employees, the services of a qualified doctor, occupational physician or other trained medical staff will be required

  2. Mining Surveillance and Maintenance Dollars

    International Nuclear Information System (INIS)

    Accelerating site cleanup to reduce facility risks to the workers, the public and the environment during a time of declining federal budgets represents a significant technical and economic challenge to U.S. Department of Energy (DOE) Operations Offices and their respective contractors. A significant portion of a facility's recurring annual expenses are associated with routine, long-term surveillance and maintenance (S and M) activities. However, ongoing S and M activities do nothing to reduce risks and basically spend money that could be reallocated towards facility deactivation. This paper discusses the background around DOE efforts to reduce surveillance and maintenance costs, one approach used to perform cost reviews, lessons learned from field implementation and what assistance is available to assist DOE sites in performing these evaluations

  3. SCORPIO - VVER core surveillance system

    International Nuclear Information System (INIS)

    The Halden Project has developed the core surveillance system SCORPIO which has two parallel modes of operation: the Core Follow Mode and the Predictive Mode. The main motivation behind the development of SCORPIO is to make a practical tool for reactor operators which can increase the quality and quantity of information presented on core status and dynamic behavior. This can first of all improve plant safety as undesired core conditions are detected and prevented. Secondly, more flexible and efficient plant operation is made possible. So far the system has only been implemented on western PWRs but the basic concept is applicable to a wide range of reactor including WWERs. The main differences between WWERs and typical western PWRs with respect to core surveillance requirements are outlined. The development of a WWER version of SCORPIO was initiated in cooperation with the Nuclear Research Institute at Rez and industry partners in the Czech Republic. The first system will be installed at the Dukovany NPP. (author)

    2015-03-01

    Full Text Available Background: Wilms tumour is a comparatively common paediatric malignancy with a relatively good prognosis. Routine post-treatment surveillance at our institution currently includes regular abdominopelvic computed tomography (CT over a two-year period for the early detection of disease recurrence. The rationale is that early salvage therapy may improve overall patient survival, and thus justifies the exposure to potentially harmful ionising radiation. Objective: To critically evaluate the routine use of post-treatment abdominopelvic CT by determining the detection rate of disease recurrence and associated clinical outcomes.Methods: Sixty-four patients in remission following initial treatment for Wilms tumour were included in this retrospective study. Variables obtained from patient records included gender, age, histological grading and tumour stage at presentation, number of abdominopelvic CT scans, site(s of relapse, method of recurrence detection and confirmation, time to recurrence and clinical outcome. Results: The patients received a total of 334 surveillance abdominopelvic CT scans. Nine (14% patients developed disease recurrence during the follow-up period. In three cases, the initial detection method was abdominopelvic CT. All three of these patients subsequently died despite salvage therapy (22 months median survival. Five false-positive diagnoses of recurrence occurred, with two being made on abdominopelvic CT. Conclusion: Routine post-treatment abdominopelvic CT showed a low detection rate of disease recurrence in children treated for Wilms tumour, while subjecting patients to a large radiation burden. The recommendation is that current practice be changed in line with the ultrasound-based Société Internationale d’Oncologie Pédiatrique (SIOP imaging guidelines.

    2005-11-01

    Adolescents comprise an eclectic mix of people vitally important to society yet long-term comprehensive studies on the circumstances of their deaths are lacking in the pediatric forensic literature. The authors reviewed all forensic cases referred to the Medical University of South Carolina Forensic Pathology section over the fifteen years between January 1989 and December 2003. In accordance with the World Health Organization (WHO) definition of adolescents, only decedents 10-19 years of age were included. The authors examined the cause and manner of death, age, gender, and race of the victims in all cases. The toxicology results, perpetrator, death scenario and location, and victim traits were analyzed when available. For all adolescents, the most common manner of death was accident followed by homicide, suicide, natural, and undetermined. Within the adolescent population two distinct groups, 10-14 years old and 15-19 years old, were identified. Though both groups were similar in that they experienced a high number of accidental deaths, decedents of older age group suffered a higher percentage of violent deaths while decedents of the younger group were more likely to die of natural causes. Many of the accidental deaths in this review were preventable, including deaths due to motor vehicle collisions and drowning. In deaths due to homicide, the perpetrator was often known to the victim, whether as an acquaintance or family member. Toxicology testing was often positive in decedents of the older age group, while only rarely positive in decedents of the younger age group. With a solid understanding of the circumstances, it may be possible to predict, and hopefully prevent, future cases of adolescent death. The authors present their findings in this 15-year retrospective study to better aid forensic pathologists, death investigators, law enforcement, and epidemiologists. PMID:16382843

  8. Performance indicators for rinderpest surveillance

    International Nuclear Information System (INIS)

    In 1986, the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture initiated a programme of assistance to FAO and IAEA Member States for the development of effective, quality assured veterinary laboratory diagnostic services. This programme introduced the use of standardized and internationally validated ELISA-based systems for the diagnosis and surveillance of the major transboundary diseases that affect livestock. This approach has proved of immense value in the monitoring of national, regional and global animal disease control and eradication programmes. One such programme focuses on the global elimination of rinderpest. Co-ordinated by FAO through the Global Rinderpest Eradication Programme (GREP) the joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture has developed critical diagnostic and epidemiological tools to assist this effort. As the final stages of the global eradication of rinderpest are reached, it is fitting that the Joint Division should again take the lead in providing guidance to Member States on how best to meet the criteria for quality assurance of national disease surveillance programmes - a prerequisite for international acceptance of freedom from a particular disease. This publication is intended to provide countries involved in rinderpest eradication with a detailed protocol for using performance indicators in evaluating their disease surveillance system and making, where necessary, adjustments to meet the criteria for acceptance specified in the OIE Rinderpest Pathway - a pathway that leads to international recognition of freedom from rinderpest. An initial publication (IAEA-TECDOC-1161) described guidelines for the use of performance indicators in rinderpest surveillance programmes. This publication now describes in detail the protocols and the linked indicators which have been developed and field validated through a series of FAO/IAEA meetings and through IAEA expert assignments to countries in Africa

    This document contains the planned 1994 schedules for routine collection of samples for the Surface Environmental Surveillance Project (SESP), Drinking Water Project, and Ground-Water Surveillance Project. Samples are routinely collected for the SESP and analyzed to determine the quality of air, surface water, soil, sediment, wildlife, vegetation, foodstuffs, and farm products at Hanford Site and surrounding communities. The responsibility for monitoring the onsite drinking water falls outside the scope of the SESP. The Hanford Environmental Health Foundation is responsible for monitoring the nonradiological parameters as defined in the National Drinking Water Standards while PNL conducts the radiological monitoring of the onsite drinking water. PNL conducts the drinking water monitoring project concurrent with the SESP to promote efficiency and consistency, utilize the expertise developed over the years, and reduce costs associated with management, procedure development, data management, quality control and reporting. The ground-water sampling schedule identifies ground-water sampling events used by PNL for environmental surveillance of the Hanford Site.

  14. Mobile Surveillance and Monitoring Robots

    International Nuclear Information System (INIS)

    Long-term nuclear material storage will require in-vault data verification, sensor testing, error and alarm response, inventory, and maintenance operations. System concept development efforts for a comprehensive nuclear material management system have identified the use of a small flexible mobile automation platform to perform these surveillance and maintenance operations. In order to have near-term wide-range application in the Complex, a mobile surveillance system must be small, flexible, and adaptable enough to allow retrofit into existing special nuclear material facilities. The objective of the Mobile Surveillance and Monitoring Robot project is to satisfy these needs by development of a human scale mobile robot to monitor the state of health, physical security and safety of items in storage and process; recognize and respond to alarms, threats, and off-normal operating conditions; and perform material handling and maintenance operations. The system will integrate a tool kit of onboard sensors and monitors, maintenance equipment and capability, and SNL developed non-lethal threat response technology with the intelligence to identify threats and develop and implement first response strategies for abnormal signals and alarm conditions. System versatility will be enhanced by incorporating a robot arm, vision and force sensing, robust obstacle avoidance, and appropriate monitoring and sensing equipment

    clustering method was found to be a useful tool to retrospectively group cases from our database into distinct and meaningful pathological entities. Syndrome definition from post-mortem findings is potentially useful for early outbreak detection because it uses the earliest available information on disease in wildlife. Furthermore, the proposed typology allows each case to be attributed to a syndrome, thus enabling the exhaustive surveillance of health events through time series analyses.

  18. EDF's surveillance on fuel manufacturing

    International Nuclear Information System (INIS)

    EDF has 58 PWR reactors requiring an annual supply of approximately 2,300 fuel assemblies. The issues of safety and reliability are important concerning the fuel given the risk of generic manufacturing issues. Being a nuclear power operator, EDF is responsible for the safety of the fuel being used in their vessels. EDF is subject to a French law which requires in particular the surveillance of the manufacture of the components involved in safety. This law is in some way an opportunity. It permits the entities involved to have an influence on the quality of components supplied which is an important condition to exercise an operational responsibility. EDF has applied for 30 years surveillance of the manufacturing processes of suppliers of fuel assemblies and contracts have specific clauses in order to organize this surveillance. In order to focus the surveillance on important matters, critical characteristics of the fuel have been determined between EDF and the suppliers to ensure the safety requirements. Activities related to the manufacturing and having an influence on these characteristics are subject to the surveillance required by regulation authorities. In order to obtain fuel assemblies that fulfill the safety requirements, EDF considers that several aspects need to be treated correctly: - The clear and sufficient definition of the components that constitutes the assembly (technical file: drawings and specifications), a definition which takes into account as far as possible the critical characteristics. - The demonstration of the efficiency, in terms of results, of complex manufacturing or controls steps (equipment qualification) included in the global manufacturing process (efficiency which depends on parameters that need to be defined and determined). - The definition of manufacturing processes (manufacturing quality plan) and the demonstration of their efficiency (qualification of manufacturing processes) to produce components that meet safety requirements

    Census and disposal data provide a multipurpose source of information on cattle mortality. The retrospective analyses we conducted on the data gathered in the National Cattle Register produced relevant information for describing and modelling the cattle mortality baseline and evaluating the impact of the 2007-2008 Blue Tongue epidemic on the French cattle population. This work was conducted retrospectively but showed that monitoring cattle mortality near real time could help detecting unexpected events. We are thus currently working on a timely and automated system to monitor cadaver disposal requests received by rendering plants, thanks to a data interchange system recently implemented between the Ministry of Agriculture and the fallen stock companies. Besides technical and methodological challenges, using these data for surveillance purposes raises epidemiological questions that still need to be answered. The question remains notably as to whether an abnormal increased mortality is a sensitive and timely signal for detecting unexpected health events. It appears also very challenging to identify the most adequate surveillance scale (time, space and population) and the most adequate anomaly detection algorithms to apply when the characteristics of the signals to be detected (shape, amplitude, etc.) are not known a priori. In Human health, similar systems have not yet proven their ability to detect unexpected events earlier than classical surveillance systems currently in place, but they have already demonstrated their value for real time assessment of identified and potentially dangerous events. Combined with traditional surveillance systems, we think that monitoring routinely collected data could improve the surveillance of the animal population health. Even if not used for detection purposes, cattle mortality monitoring could be used to rapidly produce information on the impact and evolution of identified events, what would facilitate decision-making regarding

  8. Towards elimination of maternal deaths: maternal deaths surveillance and response

    Directory of Open Access Journals (Sweden)

    Hounton Sennen

    2013-01-01

    Full Text Available Abstract Current methods for estimating maternal mortality lack precision, and are not suitable for monitoring progress in the short run. In addition, national maternal mortality ratios (MMRs alone do not provide useful information on where the greatest burden of mortality is located, who is concerned, what are the causes, and more importantly what sub-national variations occur. This paper discusses a maternal death surveillance and response (MDSR system. MDSR systems are not yet established in most countries and have potential added value for policy making and accountability and can build on existing efforts to conduct maternal death reviews, verbal autopsies and confidential enquiries. Accountability at national and sub-national levels cannot rely on global, regional and national retrospective estimates periodically generated from academia or United Nations organizations but on routine counting, investigation, sub national data analysis, long term investments in vital registration and national health information systems. Establishing effective maternal death surveillance and response will help achieve MDG 5, improve quality of maternity care and eliminate maternal mortality (MMR ≤ 30 per 100,000 by 2030.

  9. [Risk factors in police activities: operational criticism in surveillance programs].

    The planning of specific health surveillance programs for police officers is extremely complex due to difficulty in predictability and variety of occupational hazards. Even in the case of conventional occupational risk factors clearly identified by current regulations, particular working conditions may require specific assessment to effectively identify and quantify the risk of occupational exposure. An extensive program of health surveillance, aimed at promoting overall health and effectiveness of the operators, would be really desirable, in order to help better address a number of risks that cannot be easily predicted. The progressive increase in the average age of the working population and the increasing prevalence of chronic degenerative diseases, may also suggest the need for health surveillance procedures designed to verify continued unqualified suitability to police service, providing for the identification of diversified suitability profiles in relation to age and state of health: accordingly, in regard to our field of interest, there is a close link between medico-legal eligibility and occupational medicine.

    Full Text Available Objective: We aimed to evaluate the clinical, demographic and laboratory features of alopecia areata (AA patients who attended our policlinic in the last year.Material and Methods: The study was performed retrospectively and age, gender, family history of patients, onset age, duration and localization area of AA, number of recurrences, associated findings and laboratory findings were obtained from records. Results: The study included 132 patients. Median duration of disease was 4 months. 15.9% of the patients had a family history, 20.5% had another autoimmune disorder, 18% had nail findings, 18.5% atopy history. 6.5% of patients had nuchal nevus flammeus. Multifocal involvement was significantly higher in males. Positive correlation was detected between duration and severity of disease. The duration of disease was statistically related with increased thyroid autoantibodies. Nuchal nevus flammeus was related with total/universal AA. Low levels of iron, ferritin and hemoglobin were detected in approximately 10% of the patients. Conclusion: Our study is one of the studies investigating the largest parameters in AA patients. Our results indicate that there is a male dominance in AA and multifocal involvement is common in men. While early onset of disease, association with atopy and autoimmune disorder does not affect prognosis, antithyroid antibody positivity and association with nevus flammeus might be indicators of poorer prognosis.

    Seasonal respiratory infections place an increased burden on health services annually. We used a sentinel emergency department syndromic surveillance system to understand the factors driving respiratory attendances at emergency departments (EDs) in England. Trends in different respiratory indicators were observed to peak at different points during winter, with further variation observed in the distribution of attendances by age. Multiple linear regression analysis revealed acute respiratory infection and bronchitis/bronchiolitis ED attendances in patients aged 1-4 years were particularly sensitive indicators for increasing respiratory syncytial virus activity. Using near real-time surveillance of respiratory ED attendances may provide early warning of increased winter pressures in EDs, particularly driven by seasonal pathogens. This surveillance may provide additional intelligence about different categories of attendance, highlighting pressures in particular age groups, thereby aiding planning and preparation to respond to acute changes in EDs, and thus the health service in general.

    The epidemiology of seasonal influenza is influenced by age. During the influenza season, the European Influenza Surveillance Network (EISN) reports weekly virological and syndromic surveillance data [mostly influenza-like illness (ILI)] based on national networks of sentinel primary-care providers...... syndromic surveillance data without age group-specific virological data may be misleading. Surveillance at the European level would benefit from the reporting of age-specific influenza data....

  15. Health effects and medical surveillance

    International Nuclear Information System (INIS)

    This Practical Radiation Technical Manual is one of a series which has been designed to provide guidance on radiological protection for employers, Radiation Protection Officers, managers and other technically competent persons who have a responsibility to ensure the safety of employees working with ionizing radiation. The Manual may be used with the appropriate IAEA Practical Radiation Safety Manuals to provide adequate training, instruction or information on health effects and medical surveillance for all employees engaged in work with ionizing radiation. Sources of ionizing radiations have a large number of applications in the workplace. Usually, even where the work is performed safely, the employees involved inevitably receive small, regular exposures to radiation that are not harmful. Some applications involve sources that could deliver more significant radiation doses, particularly when poor methods are practised or an accident occurs. The radiations cannot be seen, felt or sensed by the human body in any way and excessive exposures may cause detriment to the health of a worker in a way that is not immediately apparent. When the symptoms occur, weeks or possibly years later, an untrained worker or inexperienced medical staff probably cannot recognize the effects to be due to the radiation exposure. This Manual explains how ionizing radiations can interact with and affect human tissues, the various factors that influence the outcome and the detrimental effects that may result. The medical surveillance that is appropriate for those working with radiation sources, depending on the degree of hazard of the work, is described. The Manual will be of most benefit if it forms part of more comprehensive training or is supplemented by the advice of a medically qualified expert. Where medical surveillance is appropriate for radiation employees, the services of a qualified doctor, occupational physician or other trained medical staff will be required

  16. Norovirus Surveillance: An Epidemiological Perspective.

    Science.gov (United States)

    Harris, John P

    2016-02-01

    Surveillance for norovirus is challenging because the nature of illness due to norovirus is such that the majority of people who are infected will not have any contact with medical services and are highly unlikely to have a sample collected for diagnosis. Public health advice urges people to not visit hospitals or their family physicians, to prevent the risk further spread. The recognition of the importance of this pathogen was quickly established following the introduction of surveillance of outbreaks of gastrointestinal infection in England and Wales in 1992. This period saw >1800 outbreaks of norovirus infection reported in hospitals in England, affecting >45 000 patients and staff. A new system for reporting outbreaks of norovirus infection in hospitals, the Hospital Norovirus outbreak Reporting Scheme (HNORS), began in January 2009. Summary information on outbreaks is provided by infection control staff at hospitals and includes questions on the date the first and last person in the outbreak became symptomatic and whether closure of a bay or ward was needed. In the first 3 years (2009-2011) of the HNORS surveillance scheme, 4000 outbreaks were reported, affecting 40 000 patients and 10 000 staff. Over the last 3 years, these outbreaks have been associated with an average of 13 000 patients and 3400 staff becoming ill, with 15 000 lost bed-days annually. With the possible introduction of a vaccine on the horizon, targeted research with a more integrated approach to laboratory testing and outbreak reporting is essential to a greater understanding of the epidemiology of norovirus.

    Background: Parainfluenza viruses (PIV) have been shown to contribute substantially to pediatric hospitalizations in the United States. However, to date, there has been no systematic surveillance to estimate the burden among pediatric outpatients. Methods: From August 2010 through July 2014, outpatient health care providers with enumerated patient populations in 13 states and jurisdictions participating in the Influenza Incidence Surveillance Project conducted surveillance of patients with influenza-like illness (ILI). Respiratory specimens were collected from the first 10 ILI patients each week with demographic and clinical data. Specimens were tested for multiple respiratory viruses, including PIV1–4, using reverse transcriptase–polymerase chain reaction assays. Cumulative incidence was calculated using provider patient population size as the denominator. Results: PIVs 1–3 were detected in 8.0% of 7716 ILI-related outpatient specimens: 30% were PIV1, 26% PIV2 and 44% PIV3. PIV circulation varied noticeably by year and type, with PIV3 predominating in 2010–2011 (incidence 110 per 100,000 children), PIV1 in 2011–2012 (89 per 100,000), dual predominance of PIV2 and PIV3 (88 and 131 per 100,000) in 2012–2013 and PIV3 (100 per 100,000) in 2013–2014. The highest incidence of PIV detections was among patients aged <5 years (259–1307 per 100,000). The median age at detection for PIV3 (3.4 years) was significantly lower than the median ages for PIV1 (4.5 years) and PIV2 (7.0 years; P < 0.05). Conclusions: PIVs 1–3 comprise a substantial amount of medically attended pediatric ILI, particularly among children aged <5 years. Distinct seasonal circulation patterns as well as significant differences in rates by age were observed between PIV types. PMID:26974891

It is also clear that morbidity and NS must be correlated in future studies, so that, the role of nutritional surveillance is enhanced in the Health Sector.

  9. SCORPIO - WWER core surveillance system

    International Nuclear Information System (INIS)

    The Institut for energiteknikk has developed the core surveillance system SCORPIO, which has two parallel modes of operation: the Core Follow Mode and the Predictive Mode. The main motivation behind the development of SCORPIO is to make a practical tool for reactor operators which can increase the quality and quantity of information presented on core status and dynamic behavior. This can first of all improve plant safety, as undesired core conditions are detected and prevented. Secondly, more flexible and efficient plant operation is made possible. The system has been implemented on western PWRs, but the basic concept is applicable to a wide range of reactors including WWERs. The main differences between WWERs and typical western PWRs with respect to core surveillance requirements are outlined. The development of a WWER version of SCORPIO has been done in co-operation with the Nuclear Research Institute Rez, and industry partners in the Czech Republic. The first system is installed at Dukovany NPP, where the Site Acceptance Test was completed 6. March 1998.(Authors)

  13. Cyber Surveillance for Flood Disasters

    Directory of Open Access Journals (Sweden)

    Shi-Wei Lo

    2015-01-01

    Full Text Available Regional heavy rainfall is usually caused by the influence of extreme weather conditions. Instant heavy rainfall often results in the flooding of rivers and the neighboring low-lying areas, which is responsible for a large number of casualties and considerable property loss. The existing precipitation forecast systems mostly focus on the analysis and forecast of large-scale areas but do not provide precise instant automatic monitoring and alert feedback for individual river areas and sections. Therefore, in this paper, we propose an easy method to automatically monitor the flood object of a specific area, based on the currently widely used remote cyber surveillance systems and image processing methods, in order to obtain instant flooding and waterlogging event feedback. The intrusion detection mode of these surveillance systems is used in this study, wherein a flood is considered a possible invasion object. Through the detection and verification of flood objects, automatic flood risk-level monitoring of specific individual river segments, as well as the automatic urban inundation detection, has become possible. The proposed method can better meet the practical needs of disaster prevention than the method of large-area forecasting. It also has several other advantages, such as flexibility in location selection, no requirement of a standard water-level ruler, and a relatively large field of view, when compared with the traditional water-level measurements using video screens. The results can offer prompt reference for appropriate disaster warning actions in small areas, making them more accurate and effective.

  14. Hanford Site surface environmental surveillance

    International Nuclear Information System (INIS)

    Environmental surveillance of the Hanford Site and the surrounding region is conducted to demonstrate compliance with environmental regulations, confirm adherence to US Department of Energy (DOE) environmental protection policies, support DOE environmental management decisions, and provide information to the public. The Surface Environmental Surveillance Project (SESP) is a multimedia environmental monitoring program conducted to measure the concentrations of radionuclides and chemical contaminants in the environment and assess the integrated effects of these contaminants on the environment and the public. The monitoring program includes sampling air, surface water, sediments, soil, natural vegetation, agricultural products, fish, and wildlife. Functional elements inherent in the operation of the SESP include project management, quality assurance/control, training, records management, environmental sampling network design and implementation, sample collection, sample analysis, data management, data review and evaluation, exposure assessment, and reporting. The SESP focuses on those contaminant/media combinations calculated to have the highest potential for contributing to off-site exposure. Results of the SESP indicate that contaminant concentrations in the Hanford environs are very low, generally below environmental standards, at or below analytical detection levels, and indicative of environmental levels. However, areas of elevated contaminant concentrations have been identified at Hanford. The extent of these areas is generally limited to past operating areas and waste disposal sites

    2016-01-01

    Background. The security-challenged states of Adamawa, Borno, and Yobe bear most of the brunt of the Boko Haram insurgency in Nigeria. The security challenge has led to the killing of health workers, destruction of health facilities, and displacement of huge populations. To identify areas of polio transmission and promptly detect possible cases of importation in these states, polio surveillance must be very sensitive. Methods. We conducted a retrospective review of acute flaccid paralysis surveillance in the security-compromised states between 2009 and 2014, using the acute flaccid paralysis database at the World Health Organization Nigeria Country Office. We also reviewed the reports of surveillance activities conducted in these security-challenged states, to identify strategies that were implemented to improve polio surveillance. Results. Environmental surveillance was implemented in Borno in 2013 and in Yobe in 2014. All disease surveillance and notification officers in the 3 security-challenged states now receive annual training, and the number of community informants in these states has dramatically increased. Media-based messaging (via radio and television) is now used to sensitize the public to the importance of surveillance, and contact samples have been regularly collected in both states since 2014. Conclusions. The strategies implemented in the security-challenged states improved the quality of polio surveillance during the review period. PMID:26655842

    Syndromic surveillance systems in England have demonstrated utility in the early identification of seasonal gastrointestinal illness (GI) tracking its spatio-temporal distribution and enabling early public health action. There would be additional public health utility if syndromic surveillance systems could detect or track subnational infectious disease outbreaks. To investigate using syndromic surveillance for this purpose we retrospectively identified eight large GI outbreaks between 2009 and 2014 (four randomly and four purposively sampled). We then examined syndromic surveillance information prospectively collected by the Real-time Syndromic Surveillance team within Public Health England for evidence of possible outbreak-related changes. None of the outbreaks were identified contemporaneously and no alerts were made to relevant public health teams. Retrospectively, two of the outbreaks - which happened at similar times and in proximal geographical locations - demonstrated changes in the local trends of relevant syndromic indicators and exhibited a clustering of statistical alarms, but did not warrant alerting local health protection teams. Our suite of syndromic surveillance systems may be more suited to their original purposes than as means of detecting or monitoring localized, subnational GI outbreaks. This should, however, be considered in the context of this study's limitations; further prospective work is needed to fully explore the use of syndromic surveillance for this purpose. Provided geographical coverage is sufficient, syndromic surveillance systems could be able to provide reassurance of no or minor excess healthcare systems usage during localized GI incidents.

    Achieving effective wildlife disease surveillance is challenging. The incorporation of citizen science (CS) in wildlife health surveillance can be beneficial, particularly where resources are limited and cost-effectiveness is paramount. Reports of wildlife morbidity and mortality from the public facilitate large-scale surveillance, both in time and space, which would otherwise be financially infeasible, and raise awareness of incidents occurring on privately owned land. CS wildlife disease surveillance schemes benefit scientists, the participating public and wildlife alike. CS has been employed for targeted, scanning and syndromic surveillance of wildlife disease. Whilst opportunistic surveillance is most common, systematic observations enable the standardisation of observer effort and, combined with wildlife population monitoring schemes, can allow evaluation of disease impacts at the population level. Near-universal access to digital media has revolutionised reporting modalities and facilitated rapid and economical means of sharing feedback with participants. Here we review CS schemes for wildlife disease surveillance and highlight their scope, benefits, logistical considerations, financial implications and potential limitations. The need to adopt a collaborative and multidisciplinary approach to wildlife health surveillance is increasingly recognised and the general public can make a significant contribution through CS.

  2. Surveillance practices for the next millennium

    International Nuclear Information System (INIS)

    The difficulty of defining the term 'standard practice' for surveillance in dam safety management is highlighted. A good dam safety surveillance program needs to contain all the key parts embodied in the Canadian Dam Association's (CDA) Dam Safety Guidelines. They have a basic role in defining what standard practice is, but the present CDA guidelines require strengthening as surveillance practice evolves in the near future. Surveillance is mainly a means of providing an owner, or in the case of BC Hydro, the Director of Dam Safety, senior management and the Board of Directors with up-to-date performance information which is essential for the continuing risk control of the residual risks associated with the dams. Although automated systems are being more commonly applied in a proactive manner in special situations as a real time risk control process, surveillance practice today is reactive. The need is stressed for dam owners to go beyond today's standard practice, by utilizing proactive performance-based practice, and better integrating surveillance within dam risk management. The establishment of a good surveillance program and its ongoing success is dependent on a comprehensive dam safety management program. There is a commitment on the part of BC Hydro to moving from the standard practice of the past to new directions outlined herein, which includes a detailed and comprehensive, auditable surveillance management system, with a policy of continued improvement. 11 refs., 1 tab., 1 fig

    PurposeEndovascular aneurysm repair (EVAR) is the dominant treatment strategy for abdominal aortic aneurysms. However, as a result of uncertainty regarding long-term durability, an ongoing imaging surveillance program is required. The aim of the study was to assess EVAR surveillance in Scotland and its effect on all-cause and aneurysm-related mortality.MethodsA retrospective analysis of all EVAR procedures carried out in the four main Scottish vascular units. The primary outcome measure was the implementation of post-EVAR imaging surveillance across Scotland. Patients were identified locally and then categorized as having complete, incomplete, or no surveillance. Secondary outcome measures were all-cause mortality and aneurysm-related mortality. Cause of death was obtained from death certificates.ResultsData were available for 569 patients from the years 2001 to 2012. All centers had data for a minimum of 5 contiguous years. Surveillance ranged from 1.66 to 4.55 years (median 3.03 years). Overall, 53 % had complete imaging surveillance, 43 % incomplete, and 4 % none. For the whole cohort, all-cause 5-year mortality was 33.5 % (95 % confidence interval 28.0–38.6) and aneurysm-related mortality was 4.5 % (.8–7.3). All-cause mortality in patients with complete, incomplete, and no imaging was 49.9 % (39.2–58.6), 19.1 % (12.6–25.2), and 47.2 % (17.7–66.2), respectively. Aneurysm-related mortality was 3.7 % (1.8–7.4), 4.4 % (2.2–8.9), and 9.5 % (2.5–33.0), respectively. All-cause mortality was significantly higher in patients with complete compared to incomplete imaging surveillance (p < 0.001). No significant differences were observed in aneurysm-related mortality (p = 0.2).ConclusionOnly half of EVAR patients underwent complete long-term imaging surveillance. However, incomplete imaging could not be linked to any increase in mortality. Further work is required to establish the role and deliverability of EVAR imaging surveillance.

  8. Microprocessor-based integrated LMFBR core surveillance

    International Nuclear Information System (INIS)

    This report results from a joint study of KfK and INTERATOM. The aim of this study is to explore the advantages of microprocessors and microelectronics for a more sophisticated core surveillance, which is based on the integration of separate surveillance techniques. Due to new developments in microelectronics and related software an approach to LMFBR core surveillance can be conceived that combines a number of measurements into a more intelligent decision-making data processing system. The following techniques are considered to contribute essentially to an integrated core surveillance system: - subassembly state and thermal hydraulics performance monitoring, - temperature noise analysis, - acoustic core surveillance, - failure characterization and failure prediction based on DND- and cover gas signals, and - flux tilting techniques. Starting from a description of these techniques it is shown that by combination and correlation of these individual techniques a higher degree of cost-effectiveness, reliability and accuracy can be achieved.

    Developing a surveillance system during a public health emergency is always challenging but is especially so in countries with limited public health infrastructure. Surveillance for Ebola virus disease (Ebola) in the West African countries heavily affected by Ebola (Guinea, Liberia, and Sierra Leone) faced numerous impediments, including insufficient numbers of trained staff, community reticence to report cases and contacts, limited information technology resources, limited telephone and Internet service, and overwhelming numbers of infected persons. Through the work of CDC and numerous partners, including the countries' ministries of health, the World Health Organization, and other government and nongovernment organizations, functional Ebola surveillance was established and maintained in these countries. CDC staff were heavily involved in implementing case-based surveillance systems, sustaining case surveillance and contact tracing, and interpreting surveillance data. In addition to helping the ministries of health and other partners understand and manage the epidemic, CDC's activities strengthened epidemiologic and data management capacity to improve routine surveillance in the countries affected, even after the Ebola epidemic ended, and enhanced local capacity to respond quickly to future public health emergencies. However, the many obstacles overcome during development of these Ebola surveillance systems highlight the need to have strong public health, surveillance, and information technology infrastructure in place before a public health emergency occurs. Intense, long-term focus on strengthening public health surveillance systems in developing countries, as described in the Global Health Security Agenda, is needed.The activities summarized in this report would not have been possible without collaboration with many U.S and international partners (http://www.cdc.gov/vhf/ebola/outbreaks/2014-west-africa/partners.html).

  17. Environmental surveillance at Los Alamos

    International Nuclear Information System (INIS)

    This report documents the environmental surveillance program conducted by the Los Alamos Scientific Laboratory (LASL) in 1978. Routine monitoring for radiation and radioactive or chemical substances is conducted on the Laboratory site and in the surrounding region to determine compliance with appropriate standards and permit early identification of possible undesirable trends. Results and interpretation of the data for 1978 on penetrating radiation, chemical and radiochemical quality of ambient air, surface and groundwater, municipal water supply, soils and sediments, food, and airborne and liquid effluents are included. Comparisons with appropriate standards and regulations or with background levels from natural or other non-LASL sources provide a basis for concluding that environmental effects attributable to LASL operations are minor and cannot be considered likely to result in any hazard to the population of the area. Results of several special studies provide documentation of some unique environmental conditions in the LASL environs

  18. Investigation on reconstitution of reactor pressure vessel surveillance specimen

    International Nuclear Information System (INIS)

    Since the reconstitution of surveillance specimens became an issue due to the shortage of surveillance test specimens for reactor pressure vessels (RPVs) for long-term operation of nuclear power plants, investigation research had been conducted for seven years until March 2006. As the standard Charpy and CT specimen reconstitution, minimum insert length was obtained from hardness distribution and twice of the sum of plastic zone width plus maximum of heat affected zone width and heat recovery zone width. Plastic zone width was correlated with absorbed energy (J) for Charpy impact test specimen (5.3 mm maximum) and J-integral (kJ/m2) for CT test specimen. Heat affected zone was checked by etching, and 1.2 mm for Charpy specimen of surface activated joining reconstitution and 1.6 mm for CT specimen of laser welding reconstitution. Heat recovery width was obtained by test measurement or thermal analysis of temperature history of inserts under the joining condition, and 1.9 mm for Charpy specimen of surface activated joining reconstitution and 2.5 mm for CT specimen of laser welding reconstitution. Standard surveillance specimen reconstitution could contribute to assessment of the integrity of aged RPVs. (T. Tanaka)

    Surveillance of workers' health in the field of occupational medicine poses substantial ethical problems in view of occupational medicine's complex responsibilities towards workers and employers, preventive and protection services, workers' representatives, public healthcare and preventive medicine facilities, controlling agencies and judicial authorities. Potentially conflicting rights and duties often come into play in this sector. In the last few years various international and national bodies have drawn up codes of ethics or guidelines for the conduct of physicians in occupational medicine, three of which are of particular importance: 1) The International Ethical Code of the International Commission on Occupational Health (ICOH, 1992); 2) The Code of Conduct of the National Association of Company Doctors (ANMA, 1997); 3) The Technical and Ethical Guidelines for workers' health (ILO, 1998). The chief purpose of all these documents is to safeguard the health of workers and to guarantee the safety of the workplace by defining programmes of health supervision to match specific risks. The methods should be non-invasive and should allow for a check or efficiency. The physician is expected to have a high degree of professionalism and up-to-date skills; to be independent and impartial; to be reserved and capable of inter-disciplinary co-operation. On the basis of the above documents, a number of problematic aspects may be appraised concerning the relationship between the occupational health physician responsible for the surveillance activities of the local health authority and the relative company physician. The documents stress the importance of keeping up to date and of quality, fields in which the dominant role played by Scientific Societies is underlined. Finally it is recommended that health supervision be arranged in such a manner as to foster the professionalism and responsibility of the physician in charge rather than the formal implementation of health

  3. Household and workplace chemicals as retrospective luminescence dosemeters

    International Nuclear Information System (INIS)

    In the development of techniques for the retrospective assessment of the dose absorbed by communities living and working adjacent to the site of a nuclear accident, attention has concentrated on the use of natural minerals such as quartz and feldspar as dosemeters. These minerals are widely found in household earthenware and almost all types of bricks and concrete. Their main disadvantages are variable and often low sensitivity, and the possibility of a comparatively large natural dose prior to the accident, depending on the age of the building and the type of building material. However, there are other potential unheated crystalline materials found in the domestic and industrial environment which may also act as retrospective dosemeters, and may be considerably more sensitive. We have surveyed the thermoluminescent and optically stimulated luminescent (OSL) characteristics of several such chemicals and this paper reports on the OSL sensitivity, the size of the residual dose immediately after manufacture, stability and derived minimum detection limits.

    Government agencies, including defense and law enforcement, increasingly make use of video from surveillance systems and camera phones owned by non-government entities.Making advanced and standardized motion imaging technology available to private and commercial users at cost-effective prices would benefit all parties. In particular, incorporating thermal infrared into commercial surveillance systems offers substantial benefits beyond night vision capability. Face rendering is a process to facilitate exploitation of thermal infrared surveillance imagery from the general area of a crime scene, to assist investigations with and without cooperating eyewitnesses. Face rendering automatically generates greyscale representations similar to police artist sketches for faces in surveillance imagery collected from proximate locations and times to a crime under investigation. Near-realtime generation of face renderings can provide law enforcement with an investigation tool to assess witness memory and credibility, and integrate reports from multiple eyewitnesses, Renderings can be quickly disseminated through social media to warn of a person who may pose an immediate threat, and to solicit the public's help in identifying possible suspects and witnesses. Renderings are pose-standardized so as to not divulge the presence and location of eyewitnesses and surveillance cameras. Incorporation of thermal infrared imaging into commercial surveillance systems will significantly improve system performance, and reduce manual review times, at an incremental cost that will continue to decrease. Benefits to criminal justice would include improved reliability of eyewitness testimony and improved accuracy of distinguishing among minority groups in eyewitness and surveillance identifications.

    The study of Vertical-Axis Wind Turbine (VAWT) technology at Sandia National Laboratories started in the 1970's and concluded in the 1990's. These studies concentrated on the Darrieus configurations because of their high inherent efficiency, but other configurations (e.g., the Savonius turbine) were also examined. The Sandia VAWT program culminated with the design of the 34-m 'Test Bed' Darrieus VAWT. This turbine was designed and built to test various VAWT design concepts and to provide the necessary databases to validate analytical design codes and algorithms. Using the Test Bed as their starting point, FloWind Corp. developed a commercial VAWT product line with composite blades and an extended height-to-diameter ratio. The purpose of this paper is to discuss the design process and results of the Sandia 34-m VAWT Test Bed program and the FloWind prototype development program with an eye toward future offshore designs. This paper is our retrospective of the design, analysis, testing and commercial process. Special emphasis is given to those lessons learned that will aid in the development of an off-shore VAWT.

  10. Cancer cervix?: a retrospective study

    International Nuclear Information System (INIS)

    Anemia is very commonly seen in most of the malignancies including cancer cervix. Anemia has long been reported to adversely affect the efficacy of radiation treatment in cervical cancer. At our center, carcinoma cervix accounts for approximately 8-10% of all malignancies. The objective of this study is to see the impact of anemia in the treatment of cancer cervix. In the present study, we collected data of treatment results of FIGO stage II and III cancer cervix patients retrospectively treated in years of 2009-10. We have tried to assess the outcome of results in patients whom haemoglobin (Hb) level < 10 gm/dl and e''10 gm/dl. Out of 200 patients of disease with baseline Hb less than 10 gm/dl, 80(40%) patients had residual disease after 4 weeks of completion of treatment. Out of 168 patients with baseline Hb more than 10 gm/dl, 42(25%) had residual disease (p-0.0012 i.e highly significant). Our study shows that there is a good disease control at local site in patients with higher pretreatment Hb level. Effect of pretreatment Hb on treatment outcome in terms of overall survival, disease free survival, and local relapse free survival along with effect on corrective measures should be studied in detail.

  11. Laser technologies for on-site surveillance

    International Nuclear Information System (INIS)

    There are situations, where video surveillance based on automated scene change detection systems may prove to be ineffective. In some cases, the changes in the image are too small to be properly detected. In others, false alarms are generated without objects (or people) moving. These alarms may be caused by changes in illumination, e.g., a faulty lamp or spurious reflections in places near water pools. Further, the absence of illumination during a blackout (whether it is caused by accident or on purpose) prevents cameras from their surveillance operation. There are high security installations for which it is necessary to introduce reliable, independent and effective sensors that can keep the surveillance work even during a blackout. Laser range scanners are electronic instruments measuring the distance from the instrument itself to the outside world along a specific direction. The type of the instrument to use depends on the range of distances to measure. The deflection of the laser beam (e.g., using a rotating mirror) enables the acquisition of the distance profiles of the surrounding premises in a very short time. Alarms are generated by comparing acquired distance measurements (organized as profiles - 2D Laser Surveillance, or in clouds of points - 3D Laser Surveillance) with previously acquired references. This is most effective for real-time detection of even small changes in the environment. The main feature of laser surveillance system is that it measures distances between the instrument itself and the real world, rather than measuring only appearance as video surveillance systems do. As such, any physical change occurring within the field of site of the laser instrument is immediately measured and detected. The fact that laser systems are self-illuminating and do not depend on the external illumination make them quite effective to work during blackouts. The paper introduces laser surveillance and shows how such systems complement well already existing video

    Surveillance of fetal alcohol syndrome (FAS) is important for monitoring the effects of prenatal alcohol exposure and describing the public health burden of this preventable disorder. Building on the infrastructure of the Fetal Alcohol Syndrome Surveillance Network (FASSNet, 1997-2002), in 2009 the Centers for Disease Control and Prevention awarded 5-year cooperative agreements to three states, Arizona, Colorado, and New York, to conduct population-based surveillance of FAS. The Fetal Alcohol Syndrome Surveillance Network II (FASSNetII, 2009-2014) developed a surveillance case definition based on three clinical criteria: characteristic facial features, central nervous system abnormalities, and growth deficiency. FASSNetII modified the FASSNet methods in three important ways: (1) estimation of a period prevalence rather than birth prevalence; (2) surveillance of FAS among school-age children (ages 7-9 years) to better document the central nervous system abnormalities that are not apparent at birth or during infancy; and (3) implementation of an expert clinical review of abstracted data for probable and confirmed cases classified through a computerized algorithm. FASSNetII abstracted data from multiple sources including birth records, medical records from child development centers or other specialty clinics, and administrative databases such as hospital discharge and Medicaid. One challenge of FASSNetII was its limited access to non-medical records. The FAS prevalence that could be estimated was that of the population identified through an encounter with the healthcare system. Clinical and public health programs that identify children affected by FAS provide critical information for targeting preventive, medical and educational services in this vulnerable population.

    2012-01-01

    Prior to the 2009 H1N1 pandemic, the Pacific Island Countries and Territories (PICTs) had agreed to develop a standardised, simple syndromic surveillance system to ensure compliance with International Health Regulations requirements (rapid outbreak detection, information sharing and response to outbreaks). In October 2010, the new system was introduced and over the next 12 months implemented in 20 of 22 PICTs. An evaluation was conducted to identify strengths and weaknesses of the system, ease of use and possible points for improvement. An in-country quantitative and qualitative evaluation in five PICTs identified that the most important determinants of the system's success were: simplicity of the system; support from all levels of government; clearly defined roles and responsibilities; feedback to those who collect the data; harmonisation of case definitions; integration of data collection tools into existing health information systems; and availability of clinical and epidemiological advice from external agencies such as the World Health Organization and the Secretariat of the Pacific Community. Regional reporting of alerts, outbreaks and outbreak updates has dramatically increased since implementation of the system. This syndromic system will assist PICTs to detect future influenza pandemics and other emerging infectious diseases and to rapidly contain outbreaks in the Pacific. PMID:22817479

    In 1997, the Centers for Disease Control and Prevention, the Mexican Secretariat of Health, and border health officials began the development of the Border Infectious Disease Surveillance (BIDS) project, a surveillance system for infectious diseases along the U.S.-Mexico border. During a 3-year period, a binational team implemented an active, sentinel surveillance system for hepatitis and febrile exanthems at 13 clinical sites. The network developed surveillance protocols, trained nine surveillance coordinators, established serologic testing at four Mexican border laboratories, and created agreements for data sharing and notification of selected diseases and outbreaks. BIDS facilitated investigations of dengue fever in Texas-Tamaulipas and measles in California–Baja California. BIDS demonstrates that a binational effort with local, state, and federal participation can create a regional surveillance system that crosses an international border. Reducing administrative, infrastructure, and political barriers to cross-border public health collaboration will enhance the effectiveness of disease prevention projects such as BIDS. PMID:12533288

    This Objective of this study was to see histologic typing of prostate cancer and its relation to patient's age, as no curative therapy exists for the advanced stages. This is a retrospective study of 50 patients suffering from prostatic adenocarcinoma and admitted at Basic Medical Sciences Institute, Jinnah Postgraduate Medical Center Karachi. A total of fifty patients between ages of 50-80 years diagnosed during the period of 1990-2001 suffering from prostate cancer were included in this study. The result showed that maximum number of tumours were in age group ranging from 61-70 years, (58% of total cases). Sixteen were (32%) well-differentiated tumours, twenty-eight (56%), moderately differentiated tumours and six (12%) were labelled as undifferentiated tumours. It was concluded that the majority of tumors were moderately differentiated tumours. Early diagnosis is useful for patients; because high grade tumours have bad prognostic markers. (author)

  19. Technology readiness assessments: A retrospective

    Mankins, John C.

    2009-11-01

    The development of new system capabilities typically depends upon the prior success of advanced technology research and development efforts. These systems developments inevitably face the three major challenges of any project: performance, schedule and budget. Done well, advanced technology programs can substantially reduce the uncertainty in all three of these dimensions of project management. Done poorly, or not at all, and new system developments suffer from cost overruns, schedule delays and the steady erosion of initial performance objectives. It is often critical for senior management to be able to determine which of these two paths is more likely—and to respond accordingly. The challenge for system and technology managers is to be able to make clear, well-documented assessments of technology readiness and risks, and to do so at key points in the life cycle of the program. In the mid 1970s, the National Aeronautics and Space Administration (NASA) introduced the concept of "technology readiness levels" (TRLs) as a discipline-independent, programmatic figure of merit (FOM) to allow more effective assessment of, and communication regarding the maturity of new technologies. In 1995, the TRL scale was further strengthened by the articulation of the first definitions of each level, along with examples (J. Mankins, Technology readiness levels, A White Paper, NASA, Washington, DC, 1995. [1]). Since then, TRLs have been embraced by the U.S. Congress' General Accountability Office (GAO), adopted by the U.S. Department of Defense (DOD), and are being considered for use by numerous other organizations. Overall, the TRLs have proved to be highly effective in communicating the status of new technologies among sometimes diverse organizations. This paper will review the concept of "technology readiness assessments", and provide a retrospective on the history of "TRLs" during the past 30 years. The paper will conclude with observations concerning prospective future

    2010-01-01

    Full Text Available Public health systems have relied on public health surveillance to plan health programs, and extensive surveillance systems exist for health behaviors and chronic disease. Mental health has used a separate data collection system that emphasizes measurement of disease prevalence and health care use. In recent years, efforts to integrate these systems have included adding chronic disease measures to the Collaborative Psychiatric Epidemiology Surveys and depression measures to the Behavioral Risk Factor Surveillance System; other data collection systems have been similarly enhanced. Ongoing challenges to integration include variations in interview protocols, use of different measures of behavior and disease, different interval reference periods, inclusion of substance abuse disorders, dichotomous vs continuous variables, and approaches to data collection. Future directions can address linking surveillance efforts more closely to the needs of state programs, increasing child health measurements in surveys, and improving knowledge dissemination from survey analyses.

    The present article rescues initially the forms, content and operational projection of the epidemiological surveillance as indispensable tool for the knowledge field and public health practices. After that, we verify that the health surveillance model establishes an enlargement of this operational concept of surveillance by integrating the collectives and individuals practices in different health necessities dimensions, which includes beyond of the risks and damages control also the eco-socials determinants. In the sequence, we search to dimension the distinct levels of actuation of this sanitary practice articulated to the interventions of promotion, protection and recovery under a located and integrated logic of the unique system of Brazilian health. Finally, we argue that all the conceptual-operational model framework of public health surveillance itself constitutes as a politics and sanitary base for the consolidation of the health promotion paradigm in the collective health field.

    Full Text Available Vascular access is the lifeline of a hemodialysis patient. Currently arteriovenous fistula and graft are considered the permanent options for vascular access. Monitoring and surveillance of vascular access are an integral part of the care of hemodialysis patient. Although different techniques and methods are available for identifying access dysfunction, the scientific evidence for the optimal methodology is lacking. A small number of randomized controlled trials have been performed evaluating different surveillance techniques. We performed a study of the recent literature published in the PUBMED, to review the scientific evidence on different methodologies currently being used for surveillance and monitoring and their impact on the care of the dialysis access. The limited randomized studies especially involving fistulae and small sample size of the published studies with conflicting results highlight the need for a larger multicentered randomized study with hard clinical end points to evaluate the optimal surveillance strategy for both fistula and graft.

    Nagarajan, Niranjana A; Shastri, Nilabh

    2013-09-01

    The ER aminopeptidase associated with antigen processing, ERAAP (or ERAP1), is essential for trimming peptides that are presented by MHC class I molecules. ERAP1 is inhibited by human cytomegalovirus, and ERAP1 polymorphisms are associated with autoimmune diseases. How the immune system detects ERAAP dysfunction, however, is unknown. We have shown previously that ERAAP-deficient cells present an immunogenic pMHC I repertoire, that elicits CD8+ T cell response in WT mice. Additionally, we discovered that the WT CD8+ T cells recognized novel peptides presented by non-classical, or MHC class Ib, molecules on ERAAP-deficient cells. The MHC Ib restricted WT CD8 T cells eliminated ERAAP-deficient cells in vitro and in vivo. We identified the FL9 peptide, presented by Qa-1(b), a MHC class Ib molecule exclusively on ERAAP-deficient cells. Remarkably, T cells specific for the FL9-Qa-1(b) complex were frequent in naïve WT mice, and had an antigen-experienced phenotype. Thus, novel non-classical pQa-1(b) complexes direct cytotoxic T cells to target cells with defective peptide processing in the endoplasmic reticulum. Here, we discuss the implications of our findings, and the possible roles of pMHC Ib-specific T cells in immune surveillance for ERAAP dysfunction. PMID:23433779

  14. Detection and surveillance by satellite

    International Nuclear Information System (INIS)

    In parallel with the conventional methods used for detecting nuclear explosions and revealing signs of proliferation and, as a consequence, the monitoring of human activities. Among the main advantages of satellites is their ability to carry out non-intrusive observations of any part of the Earth's surface at all times, while remaining in full compliance with legal requirements. Satellite-based detection is based on the electromagnetic pulse (EMP) and various optical effects. The modification of signals as they traverse the atmosphere and ionosphere should also be taken into account, but such changes in no way hinder the detection. Ultra-high frequencies are the most suitable for detection since they are less affected by the ionosphere. Signals propagated in this way are characteristic and can be distinguished from those due to lightning storms. However, some important questions arise because of the recent discovery of a new type of lightning which propagates from the tops of clouds towards the ionosphere. The electromagnetic signal in some respects is similar to that produced by an explosion. Site surveillance depends on the analysis and processing of satellite imagery such as obtained by SPOT, Landsat or ERSI. More precise measurements obtained by interferometry (ERSI) enable the observation of small-amplitude strains with can lead to the discrimination of natural seismic events from nuclear explosions.

    Full Text Available Abstract Background Oral lichen planus (OLP is a chronic autoimmune disease characterized by multiple clinical presentations and a relatively high prevalence in the population. This retrospective patient record study investigated the profile of OLP in a group of Brazilian patients seen between 1989 and 2009. Findings The clinical records were analyzed and data such as gender, age, race, clinical presentation of OLP, site affected, presence of symptoms and extraoral manifestations of the disease, smoking habit, and consumption of alcoholic beverages were obtained. Among the 1822 records of patients with oral mucosal lesions, OLP was identified in 6.03%. Of these, 76.36% were females, with a mean age of 54 years, and 85% were whites. The reticular form was the most frequent (81.81%. Extraoral lesions were observed in 32.72% of the patients and painful symptoms were reported by 50.90%. The cheek mucosa was the site most affected (92.72% and multiple oral lesions were observed in 77.27% of the patients. Among patients with OLP, 18.18% reported a smoking habit and 29.09% the consumption of alcoholic beverages. Conclusions This retrospective study showed a relatively high prevalence of OLP in the population studied, with a predominance of the disease among middle-aged white women and bilateral involvement of the cheek mucosa. Reticular lesions were the most frequent, followed by the erosive form which is mainly associated with painful symptoms. No relationship with tobacco or alcohol consumption was observed.

    Objectives: To investigate the epidemiological and clinical characteristics of oral lichen planus (OLP) in a group of Croatian patients seen between 2006 and 2012. Study Design: A group of 563 patients with a diagnosis of OLP was retrospectively reviewed in our clinic. Data regarding age, gender, medical history, drugs, smoking, alcohol, chief complaint, clinical type, localization, histology, treatment and malignant transformation were registered. Results: Of the 563 patients, 414 were females and 149 were males. The average age at the diagnosis was 58 (range 11-94). The most common site was buccal mucosa (82.4%). Most of our patients did not smoke (72.5%) or consume alcohol (69.6%). Patients reported oral soreness (43.3%), mucosal roughness (7%), xerostomia (3%), gingival bleeding (2%) and altered taste (0.5%) as the chief complaint, while almost half of them were asymptomatic (44.2%). The most common types of OLP were reticular (64.8%) and erosive (22.9%). Plaque-like (5.7%) atrophic/erythemtous (4.3%) and bullous (2.3%) type were also observed. Malignant transformation rate of 0.7% was recorded. Conclusions: OLP mostly affects non-smoking middle-aged women. Buccal mucosa is the most commonly affected site. In almost half of the cases patients are asymptomatic. In spite of the small risk for malignant transformation all patients should be regularly monitored. Key words:Oral lichen planus, malignant transformation, epidemiology, retrospective study. PMID:24608217

    OBJECTIVE To investigate the bacterial distribution and resistance in patients form 0 to 14 years of age. METHODS Under the unified program of Mohnarin, the clinical isolates were collected from the children at 0 to 14 years of age from department of pediatrics of 129 Mohnarin member hospitals and Chengdu Woman and Children Central Hospital; the drug susceptibility testing was carried out according to K-B recommended by CLSI 2010, and the statistical analysis of the data of surveillance for the collected bacteria was performed with use of WHONET 5. 5. RESULTS There were totally 25 110 strains of bacteria collected which included 14910 (59. 4%) strains of gram-negative bacteria and 10 200 (40. 6%) strains of gram-positive bacteria; the isolated bacteria ranking for the top 5 were as the following:Escherichia coli (15. 1%) , coagulase-negative Staphylococus (14. 4%) , S. Aureus (11.9%), Klebsiellia pneumonia (11. 3%), and Pseudomonas aeruginosa (7. 6%); the detection rates of methicillin-resistant S. Aureus (MRSA) and coagulase-negative Staphylococcus (MRSE)were 21. 9% and 83. 1%, respectively. No S. Aureus or MRSE isolates resistant or intermediate to vancomycin and linezolid were found. No Streptococcus isolates were found resistant or intermediate to linezolid, vancomycin, or teicoplanin; ESBLs-producing E. Coli accounted for 27. 6% , ESBLs-producing K. Pneumoniae 36. 0% , Enterobacter cloacae 33. 4% ; Enterobacteriaceae were resistant to carbopenems, the drug resistance rate of Proteus mirabilis to imipenem was 25. 3%. CONCLUSION The result of the surveillance for bacterial resistance in 4 years shows the trend of bacterial resistance , which has important guiding significance in rational use of antibiotics in treatment of bacterial infectiousdiseases in children.%目的 了解我国2010年度0~14岁细菌感染患儿病原菌构成及耐药性.方法 收集2010年1-12月129所成员单位医院的儿科及成都市妇女儿童中心医院、

    Surveillance and surveillance-like practices are common on the free web services that we use. We argue that, although such practices can provide value to users, they should be done ‘consentfully’ as a way of empowering individuals and applying consumer preference to the market. Our research on this subject raises some key challenges for interaction designers and researchers to address: explanations, timing, and measurement.

Prevention, diagnosis and therapy in cystic fibrosis, lead to the necessary collaboration between clinical and laboratory to identify effective strategies and appropriate solutions to address the problems inherent isolation micro-organisms, antibiotic strategies, overcoming of bacterial resistance and other problems management of these patients. The task of the microbiology laboratory and research in quickly and accurately, the agents responsible for these infectious processes, in order to isolate them from material, identify and determine their sensitivity antibiotics. A microbiological surveillance on 34 patients (13 males and 21 females with CF and related to the “Support Services Provincial Trento for the treatment of cystic fibrosis “in the period July 2005 - August 2008, was carried out. 180 Gram positive and 278 of Gram negative bacteria as well as 235 fungi wre collected. Staphylococcus aureus was the most frequently organism found in patients with CF with an incidence of 23% on 156 strains isolated, Pseudomonas aeruginosa was collected 19% of all microorganisms isolated corresponding to 131 strains, Candida albicans is the yeast often isolated with a frequency 22% equal to 149 isolates, Aspergillus fumigatus was isolated at a rate of 8%. From the data we collected and processed has been noted that the local epidemiology of CF patients reflects as reported in the scientific literature and national international consulting, both as a type microorganisms that frequency also isolated compared to age groups. Considering the score of Bartlett as discriminating respiratory fitness of the material, it has been observed that only 32 samples over 327 total (10% would materials insignificant. It follows therefore that the time of sample collection, followed by personnel (physiotherapists dedicated to CF patients, represents a crucial step

  18. Thyroid carcinoma. A descriptive retrospective study

    International Nuclear Information System (INIS)

    The thyroid carcinoma (TC) is not very frequent among all cancer. Its course is slow and is high potentially curable. Our aim was to analyse the characteristics in patients with TC. A retrospective analysis on 171 patients, with an average age of 41.1. (± 14.6), who asked for TC to our service between the years 2000-2004, was performed. From case histories it was evaluated: anamnesis, diagnostic image, histopathology and evolution. Tumours were grouped for size and TNM (tumor-nodule-metastasis) in stage (S). A simulated serum thyroglobulin level >2 ng/ml and positive image with 131I or another nuclear marker were considered as positive for residual TC. In the totality of the analyzed patients 88% were female, 62% below 45 years old, and in 77% the thyroid function was normal. The fine needle aspiration (FNA) was diagnostic in 78%. Papillary thyroid carcinoma (PTC) in 96%. The 63% was SI; 14% SII; 19% SIII and 4% SIV. During follow-up, we observed that 90% of patients with Tg between 2 and 10 had evidence of residual TC, and 100% with Tg > 10 ng/ml, whereas 18% of those whose simulated Tg < 2 presented positive image. There was not found significant correlation with pathologic antecedents or relevant image signs. In conclusion: TCP was the most frequent carcinoma in women, in patients younger than 45 years and in those who have euthyroid function. A simulated serum thyroglobulin level was a good indicator for residual TC, but bailed to select those patients who were disease free. (author)

This study was conducted to analyze the clinical manifestations of neurocysticercosis (NCC among seizure patients admitted to our center. Methods: We retrospectively studied all the NCC patients admitted to Neurology Department, Bir Hospital, Kathmandu, Nepal from April 2012 to February 2014. Computer tomography/magnetic resonance imaging (CT/MRI head, clinical profile, lab investigations and exclusion of other causes were the basis of the NCC diagnosis. Chi-square and Student′s t-test were used for comparison of variables. Results: Out of 131 seizure patients admitted, 21 patients were diagnosed with NCC (mean age: 33.95 ± 16.41; male: 15 (71.4%, female: 6 (28.6%. Generalized tonic clonic seizure was the most common seizure type in NCC patients (18 patients; 85.7%, two of them had status epilepticus during presentation in Emergency Department. Three patients had focal seizure, one with epilepsia partialis continua. Neuroimaging showed multiple NCC lesions in 8 (38.1% and a single NCC lesion in 13 (61.9% patients. Seven of them (33.3% sought traditional healers before being presented to our center. Eight patients (38.1% were treated with antiepileptics in local health-post without neuroimaging studies done. Calcified stage of NCC was the most frequent CT/MRI findings (12 patients; 57.1%. Phenytoin was preferred both by physicians and patients due to its low cost. Conclusion: NCC is a common finding among seizure patients in Nepal. Poor economic status, illiteracy and underdeveloped rural society are the major challenges in prevention and treatment of NCC.

    OBJECTIVE To evaluate hospital administrative data to identify potential surgical site infections (SSIs) following primary elective total hip or knee arthroplasty. DESIGN Retrospective cohort study. SETTING All acute care facilities in Alberta, Canada. METHODS Diagnosis and procedure codes for 6 months following total hip or knee arthroplasty were used to identify potential SSI cases. Medical charts of patients with potential SSIs were reviewed by an infection control professional at the acute care facility where the patient was identified with a diagnosis or procedure code. For SSI decision, infection control professionals used the National Healthcare Safety Network SSI definition. The performance of traditional surveillance methods and administrative data-triggered medical chart review was assessed. RESULTS Of the 162 patients identified by diagnosis or procedure code, 46 (28%) were confirmed as an SSI by an infection control professional. More SSIs were identified following total hip vs total knee arthroplasty (42% vs16%). Of 46 confirmed SSI cases, 20 (43%) were identified at an acute care facility different than their procedure facility. Administrative data-triggered medical chart review with infection control professional confirmation resulted in a 1.1- to 1.7-fold increase in SSI rate compared with traditional surveillance. SSIs identified by administrative data resulted in sensitivity of 90% and specificity of 99%. CONCLUSION Medical chart review for cases identified through administrative data is an efficient supplemental SSI surveillance strategy. It improves case-finding by increasing SSI identification and making identification consistent across facilities, and in a provincial surveillance network it identifies SSIs presenting at nonprocedure facilities.

  4. Surveillance programme and upgrading of the High Flux Reactor Petten

    International Nuclear Information System (INIS)

    The High Flux Reactor (HFR) at Petten (The Netherlands), a 45 MW light water cooled and moderated research reactor in operation during more than 30 years, has been kept up to date by replacing ageing components. In 1984, the HFR was shut down for replacement of the aluminium. reactor vessel which had been irradiated during more than 20 years. The demonstration that the new vessel contains no critical defect requires knowledge of the material properties of the aluminium alloy Al 5154 with and without neutron irradiation and of the likely defect presence through the periodic in-service inspections. An irradiation damage surveillance programme has been started in 1985 for the new vessel material to provide information on fracture mechanics properties. After the vessel replacement, the existing process of continuous upgrading and replacement of ageing components was accelerated. A stepwise upgrade of the control room is presently under realization.

    2016-01-01

    Background: Recent guidelines recommend against routine screening for prostate cancer, partly because of the risks associated with overtreatment of clinically indolent tumours. We aimed to determine the proportion of patients whose low-grade prostate cancer was managed by active surveillance instead of immediate treatment. Methods: We reviewed data for patients who were referred to the Ottawa regional Prostate Cancer Assessment Clinic with abnormal results for prostate-specific antigen (PSA) or prostate examination between Apr. 1, 2008, and Jan. 31, 2013. Patients with subsequent biopsy-proven low-grade (Gleason score 6) cancer were included. Active surveillance was defined a priori as monitoring by means of PSA, digital rectal examination and repeat biopsies, with the potential for curative-intent treatment in the event of disease progression. Results: Of 477 patients with low-grade cancer, active surveillance was used for 210 (44.0%), and the annual proportion increased from 32% (11/34) in 2008 to 67% (20/30) in 2013. Factors associated with immediate treatment were palpable tumour, PSA density above 0.2 ng/mL2 and more than 2 positive biopsy cores. Factors associated with surveillance were age over 70 years and higher Charlson comorbidity index. Of 173 men who received immediate surgical treatment, 103 (59.5%) had higher-grade or advanced-stage disease on final pathologic examination. Of the 210 men with active surveillance, 62 (29.5%) received treatment within a median of 1.3 years, most commonly (52 [84%]) because of upgrading of disease on the basis of surveillance biopsy. Interpretation: Active surveillance has become the most common management strategy for men with low-grade prostate cancer at our regional diagnostic centre. Factors associated with immediate treatment reflected those that increase the risk of higher-grade tumours. PMID:26927971

  7. Unforeseen costs of cutting mosquito surveillance budgets.

    Directory of Open Access Journals (Sweden)

    Gonzalo M Vazquez-Prokopec

    Full Text Available A budget proposal to stop the U.S. Centers for Disease Control and Prevention (CDC funding in surveillance and research for mosquito-borne diseases such as dengue and West Nile virus has the potential to leave the country ill-prepared to handle new emerging diseases and manage existing ones. In order to demonstrate the consequences of such a measure, if implemented, we evaluated the impact of delayed control responses to dengue epidemics (a likely scenario emerging from the proposed CDC budget cut in an economically developed urban environment. We used a mathematical model to generate hypothetical scenarios of delayed response to a dengue introduction (a consequence of halted mosquito surveillance in the City of Cairns, Queensland, Australia. We then coupled the results of such a model with mosquito surveillance and case management costs to estimate the cumulative costs of each response scenario. Our study shows that halting mosquito surveillance can increase the management costs of epidemics by up to an order of magnitude in comparison to a strategy with sustained surveillance and early case detection. Our analysis shows that the total costs of preparedness through surveillance are far lower than the ones needed to respond to the introduction of vector-borne pathogens, even without consideration of the cost in human lives and well-being. More specifically, our findings provide a science-based justification for the re-assessment of the current proposal to slash the budget of the CDC vector-borne diseases program, and emphasize the need for improved and sustainable systems for vector-borne disease surveillance.

  8. Distributed data processing for public health surveillance

    2006-09-01

    Full Text Available Abstract Background Many systems for routine public health surveillance rely on centralized collection of potentially identifiable, individual, identifiable personal health information (PHI records. Although individual, identifiable patient records are essential for conditions for which there is mandated reporting, such as tuberculosis or sexually transmitted diseases, they are not routinely required for effective syndromic surveillance. Public concern about the routine collection of large quantities of PHI to support non-traditional public health functions may make alternative surveillance methods that do not rely on centralized identifiable PHI databases increasingly desirable. Methods The National Bioterrorism Syndromic Surveillance Demonstration Program (NDP is an example of one alternative model. All PHI in this system is initially processed within the secured infrastructure of the health care provider that collects and holds the data, using uniform software distributed and supported by the NDP. Only highly aggregated count data is transferred to the datacenter for statistical processing and display. Results Detailed, patient level information is readily available to the health care provider to elucidate signals observed in the aggregated data, or for ad hoc queries. We briefly describe the benefits and disadvantages associated with this distributed processing model for routine automated syndromic surveillance. Conclusion For well-defined surveillance requirements, the model can be successfully deployed with very low risk of inadvertent disclosure of PHI – a feature that may make participation in surveillance systems more feasible for organizations and more appealing to the individuals whose PHI they hold. It is possible to design and implement distributed systems to support non-routine public health needs if required.

  9. Further development of NPP surveillance and diagnostic systems by use of intelligent technologies

    International Nuclear Information System (INIS)

    Recent development work at ISTec/GRS has been directed to more automation of surveillance techniques by utilization of the technological progress and existing tools. Neural nets, fuzzy techniques and rule-based methods were investigated for application in feature classification and automated identification of anomalies. First applications were aimed at classification of useful patterns and suppression of non-relevant signal components in order to avoid false alarms (e.g. in acoustic monitoring) and at signal validation under normal and disturbed plant conditions. Other on-going projects are aimed at the application of the successful methods to other surveillance tasks such as on-line assessment of sensor behaviour and ageing phenomena of instrumentation. The paper gives an insight in the intelligent analysis techniques and highlights their potential use for other surveillance tasks in nuclear power plants. (author)

  11. Retrospective dosimetry using chromosome painting

    International Nuclear Information System (INIS)

    have performed our own dose response relationship, based on the frequency of stable chromosome aberrations detected by Chromosome Painting for Co60 γ-rays, with doses ranging from 0 Gy to 3 Gy delivered at a 0.4 Gy/min dose rate and painting chromosomes 1, 2 and 4, which represent 22% of the genome. We have scored reciprocal and non-reciprocal translocations, excess of painted acentrics, insertions, dicentrics and centric rings. After extrapolating the obtained frequencies to the full genome, the corresponding data set agree well with our previous results of dicentrics and centric rings and reciprocal and non reciprocal translocations, obtained using the same in vitro irradiation protocol. In order to collect information about the stability and the cumulative behavior of stable chromosome aberrations, we have retrospectively evaluated, using the Chromosome Painting calibration curve, a nuclear power plant worker sample with doses ranging from 500 mSv to 800 mSv. As a whole, the observed frequencies do not differ significantly from the expected frequencies obtained applying the calibration curve α coefficient. Some workers of this samples were previously evaluated using G-banding in 1995 and the present results agree well with the expected frequencies due to the accumulated during the last four years.

    The Magu Health and Demographic Surveillance System (Magu HDSS) is part of Kisesa OpenCohort HIV Study located in a rural area of North-Western Tanzania. Since its establishment in 1994, information on pregnancies, births, marriages, migrations and deaths have been monitored and updated between one and three times a year by trained fieldworkers. Other research activities implemented in the cohort include: sero surveys which have been conducted every 2-3 years to collect socioeconomic data, HIV sero status and health knowledge attitude and behaviour in adults aged 15 years or more living in the area; verbal autopsy (VA) interviews conducted to establish cause of death in all deaths encountered in the area; Llnking data collected at health facilities to community-based data; monitoring voluntary counselling and testing (VCT); and assessing uptake of antiretroviral treatment (ART). In addition, within the community, qualitative studies have been conducted to address issues linked to HIV stigma, the perception of ART access and adherence.In 2014, the population was over 35 000 individuals. Magu HDSS has contributed to Tanzanian estimates of fertility and mortality, and is a member of the INDEPTH network. Demographic data for Magu HDSS are available via the INDEPTH Network's Sharing and Accessing Repository (iSHARE) and applications to access HDSS data for collaborative analysis are encouraged.

    2016-05-01

    Colitis-associated colorectal neoplasia (CRN) is a well-known complication of chronic inflammation of the colon either with ulcerative colitis (UC) or colonic Crohn's disease (CD). Studies have shown that inflammatory bowel disease (IBD) patients have an overall higher risk for colorectal dysplasia and cancer compared to the general population and this risk is further increased by certain associated factors, including extent of disease, duration of disease, and age at onset. In addition, other risk factors not related to IBD can also further increase the risk for CRN, such as a family history of sporadic colon cancer and a concomitant diagnosis of primary sclerosing cholangitis. The society guidelines mostly agree on the appropriate time to begin CRN surveillance but vary somewhat on the appropriate intervals between surveillance colonoscopies. In addition, there is not yet a consensus on the appropriate method for surveillance. In this review, we discuss the risk for CRN in colonic IBD, the associated factors that further increase the risk for CRN, the current surveillance guidelines and the current methods available for CRN surveillance.

    Full Text Available Abstract Background STI surveillance systems are subject to qualitative and quantitative underreporting. General practitioners (GPs, who are key subjects in case reporting, explain their underreporting partly by their observation that taking a sexual history is embarrassing for patients, and that patients are reluctant to disclose information on their sexual practices. In this study we examine patients' willingness to provide data for STI surveillance. Methods A questionnaire-based survey in a stratified population sample of 300 patients aged 18–60 years. Results The large majority of respondents stated to be willing to give information on their sexual practices for the purpose of STI surveillance. They preferred to answer sexual history questions to their GP; filling in a form on the internet was the second best option. Conclusion Based on these results, it is unlikely that the cooperation of patients would be a weak link in STI surveillance strategies. This observation, together with the fact that the majority of patients at risk for STIs have regular access to general practice services, justify renewed efforts to enliven primary care-based STI surveillance strategies.

  15. Surveillance and Resilience in Theory and Practice

    2015-09-01

    Full Text Available Surveillance is often used as a tool in resilience strategies towards the threat posed by terrorist attacks and other serious crime. “Resilience” is a contested term with varying and ambiguous meaning in governmental, business and social discourses, and it is not clear how it relates to other terms that characterise processes or states of being. Resilience is often assumed to have positive connotations, but critics view it with great suspicion, regarding it as a neo-liberal governmental strategy. However, we argue that surveillance, introduced in the name of greater security, may itself erode social freedoms and public goods such as privacy, paradoxically requiring societal resilience, whether precautionary or in mitigation of the harms it causes to the public goods of free societies. This article develops new models and extends existing ones to describe resilience processes unfolding over time and in anticipation of, or in reaction to, adversities of different kinds and severity, and explores resilience both on the plane of abstract analysis and in the context of societal responses to mass surveillance. The article thus focuses upon surveillance as a special field for conceptual analysis and modelling of situations, and for evaluating contemporary developments in “surveillance societies”.

    Full Text Available Abstract Background Recent studies have demonstrated that pathological analysis of retroperitoneal residual masses of patients with testicular germ cell tumors revealed findings of necrotic debris or fibrosis in up to 50% of patients. We aimed at pursuing a clinical and pathological review of patients undergoing post chemotherapy retroperitoneal lymph node dissection (PC-RPLND in order to identify variables that may help predict necrosis in the retroperitoneum. Methods We performed a retrospective analysis of all patients who underwent PC-RPLND at the University Hospital of the University of São Paulo and Cancer Institute of Sao Paulo between January 2005 and September 2011. Clinical and pathological data were obtained and consisted basically of: measures of retroperitoneal masses, histology of the orchiectomy specimen, serum tumor marker and retroperitoneal nodal size before and after chemotherapy. Results We gathered a total of 32 patients with a mean age of 29.7; pathological analysis in our series demonstrated that 15 (47% had necrosis in residual retroperitoneal masses, 15 had teratoma (47% and 2 (6.4% had viable germ cell tumors (GCT. The mean size of the retroperitoneal mass was 4.94 cm in our sample, without a difference between the groups (P = 0.176. From all studied variables, relative changes in retroperitoneal lymph node size (P = 0.04, the absence of teratoma in the orchiectomy specimen (P = 0.03 and the presence of choriocarcinoma in the testicular analysis after orchiectomy (P = 0.03 were statistically significant predictors of the presence of necrosis. A reduction level of 35% was therefore suggested to be the best cutoff for predicting the absence of tumor in the retroperitoneum with a sensitivity of 73.3% and specificity of 82.4%. Conclusions Even though retroperitoneal lymph node dissection remains the gold standard for patients with residual masses, those without teratoma in the primary tumor and a shrinkage

    The emergence and spread of drug-resistant tuberculosis (DR-TB) has become the major concern in global TB control nowadays due to its limited therapy options and high mortality. A comprehensive evaluation for the epidemiological trends of DR-TB in mainland China, of which TB incidences remain high, is essential but lacking. This study aimed to describe the trends of DR-TB overtime, especially multidrug-resistant TB (MDR-TB); and to identify unique characteristics of MDR-TB cases compared with drug-susceptible TB cases in Mainland China.We retrospectively analyzed surveillance data collected from 36 TB prevention and control institutions in Shandong Province, China over an 8-year period. Unique characteristics of MDR-TB were identified; Chi-square test for trends and linear regression were used to assess the changes in proportions of different resistance patterns overtime.The overall MDR rate was 6.2% in our sample population. There were no statistically significant changes in the percentage of drug-susceptible, isoniazid (INH) resistance, ethambutol (EMB) resistance, streptomycin (SM) resistance, and MDR TB during our study period except that the overall rifampin (RFP) resistance and rifampin monoresistance (RMR) increased at a yearly rate of 0.2% and 0.1%, respectively. Among those with known treatment histories, a higher MDR rate of 8.7% was observed, in which 53.9% were primary MDR-TB patients, and this rate was increasing at a yearly rate of 4.1% over our study period. MDR-TB patients were more likely to be female (odds ratio [OR], 1.23; 95% confidence interval [CI], 1.05-1.34), aged 25 to 44 years (OR, 1.67; 95%CI, 1.45-1.93), retreated (OR, 11.95; 95%CI, 9.68-14.76), having prior TB contact (OR, 1.89; 95%CI, 1.19-2.78) and having cavity (OR, 1.57; 95%CI 1.36-1.81), or bilateral disease (OR, 1.45; 95%CI 1.19-1.76) on chest radiology.Persistent high levels of MDR-TB, increasing rates of primary MDR-TB and RMR characterize DR-TB cases in mainland China

    The notion of planned and unplanned complex suicides first appeared in 1974 by Marcinkowski and, since then, no systematic study of complex suicides has been published in the English forensic literature. Here, the authors present a 5-year retrospective study of complex suicides. Nineteen complex suicides were reviewed: five unplanned and 14 planned, including the first case of an unplanned complex suicide in a woman. All cases were analyzed in terms of gender, age, methods of suicide, the presence of a suicide note, and past suicide attempts, and statistically compared with a 50-case sample of simple suicides. A further comparison was established with compiled data from the literature. Similarities were revealed regarding incidence of complex suicides, male gender predominance, and types of methods used. In contrast, results showed a higher average age for planned complex suicide victims. Finally, the authors discuss the application of the complex suicide definition. PMID:17316249

    The aspects of plant ageing management (AM) gained increasing attention over the last ten years. Numerous technical studies have been performed to study the impact of ageing mechanisms on the safe and reliable operation of nuclear power plants. National research activities have been initiated or are in progress to provide the technical basis for decision making processes. The long-term operation of nuclear power plants is influenced by economic considerations, the socio-economic environment including public acceptance, developments in research and the regulatory framework, the availability of technical infrastructure to maintain and service the systems, structures and components as well as qualified personnel. Besides national activities there are a number of international activities in particular under the umbrella of the IAEA, the OECD and the EU. The paper discusses the process, procedure and database developed for Slovenian Nuclear Safety Administration (SNSA) surveillance of ageing process of Nuclear power Plant Krsko.(author)

  20. Surveillance dosimetry of operating power plants

    International Nuclear Information System (INIS)

    The main focus of the research efforts presently underway is the LWR power reactor surveillance program in which metallurgical test specimens of the reactor PV and dosimetry sensors are placed in three or more surveillance capsules at or near the reactor PV inner wall. They are then irradiated in a temperature and neutron flux-spectrum environment as similar as possible to the PV itself for periods of about 1.5 to 15 effective full-power years (EFPY), with removal of the last capsule at a fluence corresponding to the 30- to 40-year plant end-of-life (EOL) fluence. Because the neutron flux level at the surveillance position is greater than at the vessel, the test is accelerated wit respect to the vessel exposure, allowing early assessment of EOL conditions

    Infectious diseases such as influenza and dengue have the potential of becoming a worldwide pandemic that may exert immense pressures on existing medical infrastructures. Careful surveillance of these diseases, supported by consistent model simulations, provides a means for tracking the disease evolution. The integrated surveillance and simulation program is essential in devising effective early warning systems and in implementing efficient emergency preparedness and control measures. This paper presents a summary of simulation analysis on influenza A (H1N1) 2009 in Malaysia. This simulation analysis provides insightful lessons regarding how disease surveillance and simulation should be performed in the future. This paper briefly discusses the controversy over the experimental field release of genetically modified (GM) Aedes aegypti mosquito in Malaysia. Model simulations indicate that the proposed release of GM mosquitoes is neither a viable nor a sustainable control strategy. ?? 2011 WIT Press.

  2. Application of PGNAA to plutonium surveillance

    International Nuclear Information System (INIS)

    Prompt gamma-ray neutron activation analysis (PGNAA) is a well-established tool for nondestructive elemental analysis of bulk samples. At Los Alamos National Laboratory we are investigating the use of PGNAA as a diagnostic tool for a number of applications, particularly matrix characterization for nondestructive assay and plutonium surveillance. Surveillance is an essential feature of most plutonium facility operations, including routine material processing and research, short-term storage, and processing operations prior to disposal or long-term storage. The ability to identify and assay specific elements from gamma-ray-produced active neutron interrogation (e.g., by neutron capture, nonelastic scattering, and the decay of activation products) makes PGNAA an ideal tool for surveillance. For example, PGNAA can help confirm item descriptions (for example, plutonium chloride versus plutonium oxide). This feature is particularly important in operations involving poorly characterized legacy materials where the material form could adversely impact plutonium-processing operations

  4. Improvements to Technical Specifications surveillance requirements

    International Nuclear Information System (INIS)

    In August 1983 an NRC task group was formed to investigate problems with surveillance testing required by Technical Specifications, and to recommend approaches to effect improvements. NUREG-1024 (''Technical Specifications-Enhancing Safety Impact'') resulted, and it contained recommendations to review the basis for test frequencies; to ensure that the tests promote safety and do not degrade equipment; and to review surveillance tests so that they do not unnecessarily burden personnel. The Technical Specifications Improvement Program (TSIP) was established in December 1984 to provide the framework for rewriting and improving the Technical Specifications. As an element of the TSIP, all Technical Specifications surveillance requirements were comprehensively examined as recommended in NUREG-1024. The results of that effort are presented in this report. The study found that while some testing at power is essential to verify equipment and system operability, safety can be improved, equipment degradation decreased, and unnecessary personnel burden relaxed by reducing the amount of testing at power

    This paper describes tools used to measure periodontal diseases and the integration of these tools into surveillance systems. Tools to measure periodontal diseases at the surveillance level have focussed on current manifestations of disease (e.g. gingival inflammation) or disease sequelae (e...... diseases. Therefore, some of these tools are no longer valid. Others, such as loss of periodontal attachment, are the current de-facto tools but demand many resources to undertake periodical assessment of the periodontal health of populations. Less complex tools such as the Community Periodontal Index......-report measures, are currently under validation. In this paper, we do not review indices designed to measure plaque or residual accumulation around the tooth, indices focussed only on gingival inflammation or radiographic approaches with limited applicability in surveillance systems. Finally, we review current...

  6. Digital image surveillance for IAEA safeguards

    International Nuclear Information System (INIS)

    Basic technologies utilized for optical surveillance equipment for IAEA safeguards are mostly dictated by the trends in the commercial market. When in the late 1970s the 8 mm amateur movie film market was gradually subsumed in the market for video home system cameras and video cassette recorders, the IAEA had to cope with this trend and consequently embarked upon developing surveillance equipment by adapting the technology developed for the domestic and security markets. Currently, there is a technological trend towards digital imaging, digital processing, digital storage and digital transmission of image data which will probably continue during the next ten years. The paper describes the move to digital image surveillance, which is planned for IAEA safeguards, and its advantages for present and recommended future approaches, as well as its requirements and limitations.

    2004-01-13

    Enhanced Video Surveillance (EVS) with Speckle Imaging is a high-resolution imaging system that substantially improves resolution and contrast in images acquired over long distances. This technology will increase image resolution up to an order of magnitude or greater for video surveillance systems. The system's hardware components are all commercially available and consist of a telescope or large-aperture lens assembly, a high-performance digital camera, and a personal computer. The system's software, developed at LLNL, extends standard speckle-image-processing methods (used in the astronomical community) to solve the atmospheric blurring problem associated with imaging over medium to long distances (hundreds of meters to tens of kilometers) through horizontal or slant-path turbulence. This novel imaging technology will not only enhance national security but also will benefit law enforcement, security contractors, and any private or public entity that uses video surveillance to protect their assets.

    Behavioral research has shown that spatial cues that orient attention toward task relevant items being maintained in visual short-term memory (VSTM) enhance item memory accuracy. However, it is unknown if these retrospective attentional cues ("retro-cues") enhance memory beyond typical short-term memory delays. It is also unknown whether retro-cues affect the spatial information associated with VSTM representations. Emerging evidence suggests that processes that affect short-term memory maintenance may also affect long-term memory (LTM) but little work has investigated the role of attention in LTM. In the current event-related potential (ERP) study, we investigated the duration of retrospective attention effects and the impact of retrospective attention manipulations on VSTM representations. Results revealed that retro-cueing improved both VSTM and LTM memory accuracy and that posterior maximal ERPs observed during VSTM maintenance predicted subsequent LTM performance. N2pc ERPs associated with attentional selection were attenuated by retro-cueing suggesting that retrospective attention may disrupt maintenance of spatial configural information in VSTM. Collectively, these findings suggest that retrospective attention can alter the structure of memory representations, which impacts memory performance beyond short-term memory delays. PMID:27038756

  12. Laser technologies for on-site surveillance

    International Nuclear Information System (INIS)

    Surveillance techniques are based on the detection of changes. These changes can be caused by moving objects or people, or by modifications made to the environment itself. Visual surveillance uses optical means, e.g., the analysis of an image acquired by a surveillance camera. These techniques are effective in detecting objects moving within the surveyed area. There are situations, however, where optical surveillance may prove to be unreliable. In some cases, the changes in the image are too small to be properly detected with scene change detectors. In other cases, alarms are generated without objects (or people) moving. These false alarms may be caused by changes in illumination, e.g., a faulty lamp or spurious reflections in places near water pools. Further, the absence of illumination during a blackout (whether it is caused by accident or on purpose) prevents cameras from their surveillance operation. There are high security installations for which it is necessary to introduce reliable, independent and effective sensors that can keep the surveillance work even during a blackout. Laser range scanners are electronic instruments measuring the distance from the instrument itself to the outside world along a specific direction. The type of the instrument to use depends on the range of distances to measure. Indeed, whereas for large distances (e.g. between 1 and 200m) it is possible to use time-of-flight instruments, for short distances (e.g., from a few centimetres to about 1.5m) a triangulation laser striping system is used. The deflection of the laser beam (e.g., using rotating mirrors) enables the acquisition of the distance profiles (or matrices) of the surrounding premises in a very short time

    2000-01-01

    Epidemiological surveillance, namely the continuous monitoring of diseases and health determinants in a population, has developed over the past fifteen years, in the sphere of human health as well as in animal health. All epidemiological surveillance networks include the following four stages: data collection, data transmission, data processing and dissemination of information. However, despite this basic similarity, the very many networks existing in France are extremely varied in nature. At the national level, the bodies involved in epidemiological surveillance for infectious animal diseases are the Direction générale de l'alimentation, the Agence française de sécurité sanitaire des aliments and, to a lesser degree, the Institut français de recherche pour l'exploitation de la mer. In the field, the networks rely on the Direction des services vétérinaires, veterinary practitioners, laboratories in each département, and livestock producers' groups (especially animal health protection groups). Some twenty French networks currently in operation are presented in this article according to a classification based on published criteria. In the case of human infectious diseases, epidemiological surveillance is carried out almost entirely by the Direction générale de la santé and the Directions départementales d'action sanitaire et sociale, the Institut de veille sanitaire and the various Centres nationaux de référence (CNRs). Most human infectious diseases are monitored by one or more of the following broad categories of networks: reporting of notifiable diseases, the CNRs, the network of sentinel doctors, the network of hospital laboratories and departments, and medical causes of death. An example where surveillance is covered by several networks is also presented, namely surveillance for salmonellosis and Salmonella. Lastly, methods for evaluating networks are discussed.

For instance, first hints to disease outbreaks, customer preferences, or political changes could be identified with this data. Surveillance or early warning systems enable such detection of changes and support humans in getting information on changing situations. However, the variety of data that could be considered for surveillance is immense, ranging from sensor-measured values to collected counts and information extra

  17. Risk based surveillance test interval optimization

    International Nuclear Information System (INIS)

    First step towards the risk based regulation is to determine the optimal surveillance test intervals for the safety equipment which is tested at nuclear power plant operation. In the paper we have presented the process of optimal surveillance test interval optimization from our perspective. It consist of three levels: component level, system level and plant level. It bases on the results of the Probabilistic Safety Assessment and is focused to minimize risk. At component and system level the risk measure is component or system mean unavailability respectively. At plant level the risk measure is core damage frequency. (author)

    Data on childhood obesity collected by the Centers for Disease Control and Prevention helped reveal the nation's epidemic of overweight and obese children. But more information is needed. Collecting body mass index (BMI)-the widely accepted measurement of childhood weight status-at the state and local levels can be instrumental in identifying and tracking obesity trends, designing interventions to help overweight children, and guiding broader policy solutions. Approximately thirty states have enacted or proposed BMI surveillance laws and regulations. Arkansas stands out as the state with the highest-quality surveillance data. Innovative strategies being pursued in a number of other states should be explored for broader dissemination. PMID:20194988

    Future surveillance systems will work in complex and cluttered environments which require systems engineering solutions for such applications such as airport ground surface management. In this paper, we highlight the use of a L1 video tracker for monitoring activities at an airport. We present methods of information fusion, entity detection, and activity analysis using airport videos for runway detection and airport terminal events. For coordinated airport security, automated ground surveillance enhances efficient and safe maneuvers for aircraft, unmanned air vehicles (UAVs) and unmanned ground vehicles (UGVs) operating within airport environments.

    Epidemiologic surveillance at DOE facilities consists of regular and systematic collection, analysis, and interpretation of data on absences due to illness and injury in the work force. Its purpose is to provide an early warning system for health problems occurring among employees at participating sites. Data are collected by coordinators at each site and submitted to the Epidemiologic Surveillance Data Center, located at the Oak Ridge Institute for Science and Education, where quality control procedures and analyses are carried out. Rates of absences and rates of diagnoses associated with absences are analyzed by occupation and other relevant variables. They may be compared with the disease experience of different groups within the DOE work force and with populations that do not work for DOE to identify disease patterns or clusters that may be associated with work activities. In this annual report, the 1994 morbidity data for BNL are summarized. These analyses focus on absences of 5 or more consecutive workdays occurring among workers aged 16-80 years. They are arranged in five sets of tables that present: (1) the distribution of the labor force by occupational category and salary status; (2) the absences per person, diagnoses per absence, and diagnosis rates for the whole work force; (3) diagnosis rates by type of disease or injury; (4) diagnosis rates by occupational category; and (5) relative risks for specific types of disease or injury by occupational category.

    Introduction Little is known about Canadian youth football injuries. The objectives of this study were (a) to contrast the injuries in Canadian and American football players aged 6 to 17 years and (b) compare the injuries sustained during organized football with those in nonorganized football. Methods Using a retrospective cohort design based on data from the Canadian Hospitals Injury Reporting and Prevention Program and the National Electronic Injury Surveillance System a comparison of injuries was made. Results Trends in injuries were comparable. Proportions and odds of injuries were similar, except for a few exceptions. In Canada, more girls were injured and fractures were more prevalent. Compared with nonorganized football, organized football players were older, involved more males, and suffered more traumatic brain injuries and injuries to their lower extremities. Conclusion Canadian and American youth football injuries were similar. The type of football, be it organized or nonorganized, has an impact on injuries. PMID:26316542

    As participation in junior, high-school and college sports has increased dramatically over the last three decades, sports injuries have increased commensurately. In the US alone, sports-related injuries account for 2.6 million visits to the emergency room made by children and young adults (aged 5-24 years). Injuries sustained by high-school athletes have resulted in 500000 doctor visits, 30000 hospitalisations and a total cost to the healthcare system of nearly 2 billion dollars per year. Sports injury surveillance studies have long formed the backbone of injury prevention research, serving to highlight the types and patterns of injury that merit further investigation. Injury surveillance studies have been integral in guiding rule changes, equipment improvement and training regimens that prevent injury. Despite findings that the methodology of injury surveillance studies may significantly influence the design and efficacy of preventative interventions, relatively few sources address epidemiological considerations involved in such studies. The purpose of this review is 3-fold. First, to perform a review of the current injury surveillance literature in order to identify key epidemiological and methodological issues that arise when reading or conducting an injury surveillance study. Second, to identify and describe how injury surveillance studies have addressed these issues. Third, to provide recommendations about the identified issues in order to guide clinicians in the interpretation of data presented in such studies. Searches of Ovid MEDLINE (1966-present) and PubMed were performed. Thirty-three descriptive and review articles addressing epidemiological and methodological considerations in injury surveillance were selected, as well as 54 cohort studies and studies with an experimental design. Data with respect to each study's treatment of the three epidemiological issues of interest were extracted and synthesised into a table. This review identifies the following

    Full Text Available Geographic and temporal variation in occurrence of dementia within the US has received little attention despite its importance for generation of new etiologic hypotheses and health services research. We examine methodological problems in the use of vital statistics data for assessing variation over time, among states and within states in the US. We analyzed the US multiple cause of death files for 2005–2006 and 1999–2000 US deaths with Alzheimer’s Disease (International Classification of Disease 10th revision code G30 and other dementias (codes F01, F02, R54 coded as underlying or contributing cause of death based on the death certificate. Age-adjusted death rates were computed by year, state or county for persons aged 65 years and over. In 2005–2006 combined, 555,904 total deaths occurred with any dementia type (212,386 for Alzheimer’s disease coded as underlying or contributing cause. Among the states, age-adjusted rates per 100,000 per year varied by two fold ranging from 458 in New York to 921 in Oregon. Similar geographic patterns were seen for Alzheimer’s disease. However, between 1999–2000 and 2005–2006 the US death rate for all dementia increased only from 559 to 695 (24% while that for Alzheimer’s disease doubled from 135 to 266. Use of specific (G30, F01 versus non-specific diagnoses (F02, R54 varied among states and over time, explaining most of the temporal increase in rate of Alzheimer’s disease. Further research is needed to assess artifacts of diagnosis, certification or coding, utilization of health services, versus biological variation as possible causes of temporal and geographic variation to enhance utility of mortality data for dementia monitoring and research.

  8. Extended surveillance as a support to PLIM

    International Nuclear Information System (INIS)

    Full text: The safe exploitation of the reactor pressure vessel was and is always a major concern in nuclear power plant life management. At present, issues like Plant Life Extension, where utilities look into the possibility of license renewal after 40 years of operation, are becoming relevant in the USA. In other countries PLIM beyond the design life of the NPP could also be desirable from the economic viewpoint. The limiting factor could, however, be the integrity of the reactor pressure vessel. The reactor pressure vessel surveillance procedures as defined by regulatory legislation is limited and can be supplemented with valuable information that can be extracted in parallel to conventional surveillance testing or through additional testing on surveillance material. This is justified for several reasons: 1. The current methodology is semi-empirical, contains flaws and is in a number of cases over conservative. Without giving in on safety, we need to try and understand the material behavior more fundamentally; 2. Some reactor surveillance materials demonstrate inconsistent behavior with respect to the overall trend. These materials are called 'outlier' materials. But are they really outliers or is this connected to the indexing methodology used? 3. Additional data, for example the results of instrumented Charpy-V impact tests, have been obtained on many surveillance test specimens and are not adequately exploited in the actual surveillance methodology; 4. Scientific research provides substantial information and understanding of degradation mechanisms in reactor pressure vessel steels. Although we will not concentrate on this topic, the development of powerful microscopic investigation techniques, like FEGSTEM, APFIM, SANS, positron annihilation, internal friction, ... led to an intensified development of radiation damage modelling and are an input to micromechanical modelling. Moreover, due to the ever increasing computer power, additional multi-scale (time and

    Full Text Available Abstract Background Infectious disease surveillance is a primary public health function in resource-limited settings. In 2003, an electronic disease surveillance system (Alerta was established in the Peruvian Navy with support from the U.S. Naval Medical Research Center Detachment (NMRCD. Many challenges arose during the implementation process, and a variety of solutions were applied. The purpose of this paper is to identify and discuss these issues. Methods This is a retrospective description of the Alerta implementation. After a thoughtful evaluation according to the Centers for Disease Control and Prevention (CDC guidelines, the main challenges to implementation were identified and solutions were devised in the context of a resource-limited setting, Peru. Results After four years of operation, we have identified a number of challenges in implementing and operating this electronic disease surveillance system. These can be divided into the following categories: (1 issues with personnel and stakeholders; (2 issues with resources in a developing setting; (3 issues with processes involved in the collection of data and operation of the system; and (4 issues with organization at the central hub. Some of the challenges are unique to resource-limited settings, but many are applicable for any surveillance system. For each of these challenges, we developed feasible solutions that are discussed. Conclusion There are many challenges to overcome when implementing an electronic disease surveillance system, not only related to technology issues. A comprehensive approach is required for success, including: technical support, personnel management, effective training, and cultural sensitivity in order to assure the effective deployment of an electronic disease surveillance system.

  17. The value of information: Current challenges in surveillance implementation.

    Science.gov (United States)

    Stärk, Katharina D C; Häsler, Barbara

    2015-11-01

    Animal health surveillance is a complex activity that involves multiple stakeholders and provides decision support across sectors. Despite progress in the design of surveillance systems, some technical challenges remain, specifically for emerging hazards. Surveillance can also be impacted by political interests and costly consequences of case reporting, particularly in relation to international trade. Constraints on surveillance can therefore be of technical, economic and political nature. From an economic perspective, both surveillance and intervention are resource-using activities that are part of a mitigation strategy. Surveillance provides information for intervention decisions and thereby helps to offset negative effects of animal disease and to reduce the decision uncertainty associated with choices on disease control. It thus creates monetary and non-monetary benefits, both of which may be challenging to quantify. The technical relationships between surveillance, intervention and loss avoidance have not been established for most hazards despite being important consideration for investment decisions. Therefore, surveillance cannot just be maximised to minimise intervention costs. Economic appraisals of surveillance need to be done on a case by case basis for any hazard considering both surveillance and intervention performance, the losses avoided and the values attached to them. This can be achieved by using an evaluation approach which provides a systematic investigation of the worth or merit of surveillance activities. Evaluation is driven by a specific evaluation question which for surveillance systems commonly considers effectiveness, efficiency, implementation and/or compliance issues. More work is needed to provide guidance on the appropriate selection of evaluation attributes and general good practice in surveillance evaluation. Due to technical challenges, economic constraints and variable levels of capacity, the implementation of surveillance systems

  18. The visibility of cancer on previous mammograms in retrospective review

    International Nuclear Information System (INIS)

    AIM: To study how many tumours were visible in restrospect on mammograms originally reported as normal or benign in patients coming to surgery with proven breast cancer. The effect of making the pre--operative mammogram available was also assessed. MATERIALS AND METHODS: Three hundred and twenty initial mammograms of consecutive new breast cancer cases were analysed by a group of radiologists in the knowledge that all patients were later diagnosed with breast cancer. The films were read twice, first without and then with the later (pre-operative) mammograms available. The parenchymal density in the location of the tumour was classified as fatty, mixed or dense, and the tumours were classified as visible or not visible. The reasons for the invisibility of the tumour in the earlier examination were analysed. RESULTS: Fourteen per cent (45) of cancers were retrospectively visible in earlier mammograms without the pre-operative mammograms having been shown, and 29% (95) when pre-operative mammograms were shown. Breast parenchymal density decreased with age and the visibility of tumours increased with age. When considered simultaneously, the effect of age (over 55 vs under 55) was greater (OR = 2.9) than the effect of density (fatty vs others) (OR = 1.5). The most common reasons for non-detection were that the lesion was overlooked (55%), diagnosed as benign (33%) or was visible only in one projection (26%). Growing density was the most common (37%) feature of those lesions originally overlooked or regarded as benign. CONCLUSIONS: Tumours are commonly visible in retrospect, but few of them exhibit specific signs of cancer, and are recognized only if they grow or otherwise change. It is not possible to differentiate most of them from normal parenchymal densities. Saaremaa, I. (2001)

  14. Syndromic surveillance for local outbreaks of lower-respiratory infections: would it work?

    Directory of Open Access Journals (Sweden)

    Cees C van den Wijngaard

    Full Text Available BACKGROUND: Although syndromic surveillance is increasingly used to detect unusual illness, there is a debate whether it is useful for detecting local outbreaks. We evaluated whether syndromic surveillance detects local outbreaks of lower-respiratory infections (LRIs without swamping true signals by false alarms. METHODS AND FINDINGS: Using retrospective hospitalization data, we simulated prospective surveillance for LRI-elevations. Between 1999-2006, a total of 290762 LRIs were included by date of hospitalization and patients place of residence (>80% coverage, 16 million population. Two large outbreaks of Legionnaires disease in the Netherlands were used as positive controls to test whether these outbreaks could have been detected as local LRI elevations. We used a space-time permutation scan statistic to detect LRI clusters. We evaluated how many LRI-clusters were detected in 1999-2006 and assessed likely causes for the cluster-signals by looking for significantly higher proportions of specific hospital discharge diagnoses (e.g. Legionnaires disease and overlap with regional influenza elevations. We also evaluated whether the number of space-time signals can be reduced by restricting the scan statistic in space or time. In 1999-2006 the scan-statistic detected 35 local LRI clusters, representing on average 5 clusters per year. The known Legionnaires' disease outbreaks in 1999 and 2006 were detected as LRI-clusters, since cluster-signals were generated with an increased proportion of Legionnaires disease patients (p:<0.0001. 21 other clusters coincided with local influenza and/or respiratory syncytial virus activity, and 1 cluster appeared to be a data artifact. For 11 clusters no likely cause was defined, some possibly representing as yet undetected LRI-outbreaks. With restrictions on time and spatial windows the scan statistic still detected the Legionnaires' disease outbreaks, without loss of timeliness and with less signals generated in

    Background. No consensus between guidelines exists regarding neuroimaging in first-episode psychosis. The purpose of this study is to assess anomalies found in structural neuroimaging exams (brain computed tomography (CT) and magnetic resonance imaging (MRI)) in the initial medical work-up of patients presenting first-episode psychosis. Methods. The study subjects were 32 patients aged 18-48 years (mean age: 29.6 years), consecutively admitted with first-episode psychosis diagnosis. Socio-demographic and clinical data and neuroimaging exams (CT and MRI) were retrospectively studied. Diagnostic assessments were made using the Operational Criteria Checklist +. Neuroimaging images (CT and MRI) and respective reports were analysed by an experienced consultant psychiatrist. Results. None of the patients had abnormalities in neuroimaging exams responsible for psychotic symptoms. Thirty-seven percent of patients had incidental brain findings not causally related to the psychosis (brain atrophy, arachnoid cyst, asymmetric lateral ventricles, dilated lateral ventricles, plagiocephaly and falx cerebri calcification). No further medical referral was needed for any of these patients. No significant differences regarding gender, age, diagnosis, duration of untreated psychosis, in-stay and cannabis use were found between patients who had neuroimaging abnormalities versus those without. Discussion. This study suggests that structural neuroimaging exams reveal scarce abnormalities in young patients with first-episode psychosis. Structural neuroimaging is especially useful in first-episode psychosis patients with neurological symptoms, atypical clinical picture and old age. PMID:27257547

    Full Text Available Since bat rabies surveillance was first implemented in France in 1989, 48 autochthonous rabies cases without human contamination have been reported using routine diagnosis methods. In this retrospective study, data on bats submitted for rabies testing were analysed in order to better understand the epidemiology of EBLV-1 in bats in France and to investigate some epidemiological trends. Of the 3176 bats submitted for rabies diagnosis from 1989 to 2013, 1.96% (48/2447 analysed were diagnosed positive. Among the twelve recognised virus species within the Lyssavirus genus, two species were isolated in France. 47 positive bats were morphologically identified as Eptesicus serotinus and were shown to be infected by both the EBLV-1a and the EBLV-1b lineages. Isolation of BBLV in Myotis nattereri was reported once in the north-east of France in 2012. The phylogenetic characterisation of all 47 French EBLV-1 isolates sampled between 1989 and 2013 and the French BBLV sample against 21 referenced partial nucleoprotein sequences confirmed the low genetic diversity of EBLV-1 despite its extensive geographical range. Statistical analysis performed on the serotine bat data collected from 1989 to 2013 showed seasonal variation of rabies occurrence with a significantly higher proportion of positive samples detected during the autumn compared to the spring and the summer period (34% of positive bats detected in autumn, 15% in summer, 13% in spring and 12% in winter. In this study, we have provided the details of the geographical distribution of EBLV-1a in the south-west of France and the north-south division of EBLV-1b with its subdivisions into three phylogenetic groups: group B1 in the north-west, group B2 in the centre and group B3 in the north-east of France.

  15. Towards One Health disease surveillance: The Southern African Centre for Infectious Disease Surveillance approach

    Directory of Open Access Journals (Sweden)

    Esron D. Karimuribo

    2012-06-01

    Full Text Available Africa has the highest burden of infectious diseases in the world and yet the least capacity for its risk management. It has therefore become increasingly important to search for ‘fit-for- purpose’ approaches to infectious disease surveillance and thereby targeted disease control. The fact that the majority of human infectious diseases are originally of animal origin means we have to consider One Health (OH approaches which require inter-sectoral collaboration for custom-made infectious disease surveillance in the endemic settings of Africa. A baseline survey was conducted to assess the current status and performance of human and animal health surveillance systems and subsequently a strategy towards OH surveillance system was developed. The strategy focused on assessing the combination of participatory epidemiological approaches and the deployment of mobile technologies to enhance the effectiveness of disease alerts and surveillance at the point of occurrence, which often lies in remote areas. We selected three study sites, namely the Ngorongoro, Kagera River basin and Zambezi River basin ecosystems. We have piloted and introduced the next-generation Android mobile phones running the EpiCollect application developed by Imperial College to aid geo-spatial and clinical data capture and transmission of this data from the field to the remote Information Technology (IT servers at the research hubs for storage, analysis, feedback and reporting. We expect that the combination of participatory epidemiology and technology will significantly improve OH disease surveillance in southern Africa.

    Full Text Available This is not a research paper on risk factor surveillance. It is an effort by a key group of researchers and practitioners of risk factor surveillance to define the current state of the art and to identify the key issues involved in the current practice of behavioral risk factor surveillance. Those of us who are the principal authors have worked and carried out research in this area for some three decades. As a result of a series of global meetings beginning in 1999 and continuing every two years since then, a collective working group of the International Union of Health Promotion and Education (IUHPE was formed under the name World Alliance of Risk Factor Surveillance (WARFS. Under this banner the organization sought to write a comprehensive statement on the importance of surveillance to health promotion and public health. This paper, which has been revised and reviewed by established peers in the field, is the result. It provides the reader with a clear summary of the major issues that need to be considered by any and all seeking to carry out behavioral risk factor surveillance.

  17. Converging requirements and emerging challenges to public health diseases surveillance and bio surveillance

    International Nuclear Information System (INIS)

    Disease surveillance systems are a critical component of an early warning system for public health agencies to prepare and respond to major public health catastrophes. With a growing emphasis for more robust early indicator and warning systems to track emerging and dangerous diseases of suspicious nature, considerable emphasis is now placed on deployment of more expanded electronic disease surveillance systems. The architectural considerations for bio surveillance information system are based on collection, analysis and dissemination of human, veterinary and agricultural related disease surveillance to broader regional areas likely to be affected in the event of an emerging disease, or due to bioterrorism and better coordinate plans, preparations and response by governmental agencies and multilateral forums. The diseases surveillance systems architectures by intent and design could as well support biological threat monitoring and threat reduction initiatives. As an illustrative sample set, this paper will describe the comparative informatics requirements for a disease surveillance systems developed by CSC for the US Centers for Diseases Control and Prevention (CDC) currently operational nationwide, and biological weapons threat assessment developed as part of the Threat Agent Detection and Response (TADR) Network under the US Biological Threat Reduction Program and deployed at Uzbekistan, Kazakhstan, Georgia, and Azerbaijan.(author)

  18. Serology for trachoma surveillance after cessation of mass drug administration.

    2015-02-01

    Full Text Available Trachoma, caused by Chlamydia trachomatis (Ct, is the leading infectious cause of blindness worldwide. Yearly azithromycin mass drug administration (MDA plays a central role in efforts to eliminate blinding trachoma as a public health problem. Programmatic decision-making is currently based on the prevalence of the clinical sign "trachomatous inflammation-follicular" (TF in children. We sought to test alternative tools for trachoma surveillance based on serology in the 12-year cohort of Kahe Mpya, Rombo District, Tanzania, where ocular chlamydial infection was eliminated with azithromycin MDA by 2005.The present study was a community-based cross-sectional survey in Kahe Mpya. Of 989 residents, 571 people aged 6 months to 87 years were enrolled: 58% of the total population and 73% of 1-9 year olds, the key WHO indicator age group. Participants were examined for TF, had conjunctival swabs collected for nucleic acid amplification test (NAAT-based detection of Ct, and blood collected for analysis of antibodies to the Ct antigens pgp3 and CT694 by multiplex bead-based immunoassay. Seroconversion rate was used to estimate changes in the force of infection in a reversible catalytic model. No conjunctival swabs tested positive for Ct infection by NAAT. Among 1-9 year olds, TF prevalence was 6.5%, whereas only 3.5% were seropositive. Force of infection modelling indicated a 10-fold decrease in seroconversion rate at a time corresponding to MDA commencement. Without baseline serological data, the inferences we can make about antibody status before MDA and the longevity of the antibody response are limited, though our use of catalytic modelling overcomes some of these limitations.Serologic tests support NAAT findings of very low to zero prevalence of ocular Ct in this community and have potential to provide objective measures of transmission and useful surveillance tools for trachoma elimination programs.

    Classical swine fever (CSF) is a highly contagious pig disease that causes economic losses and impaired animal welfare. Improving the surveillance system for CSF can help to ensure early detection of the virus, thereby providing a better initial situation for controlling the disease. Economic analysis is required to compare the benefits of improved surveillance with the costs of implementing a more intensive system. This study presents a comprehensive economic analysis of CSF surveillance in the Netherlands, taking into account the specialized structure of Dutch pig production, differences in virulence of CSF strains and a complete list of possible surveillance activities. The starting point of the analysis is the current Dutch surveillance system (i.e. the default surveillance-setup scenario), including the surveillance activities 'daily clinical observation by the farmer', 'veterinarian inspection after a call', 'routine veterinarian inspection', 'pathology in AHS', 'PCR on tonsil in AHS', 'PCR on grouped animals in CVI' and 'confirmatory PCR by NVWA'. Alternative surveillance-setup scenarios were proposed by adding 'routine serology in slaughterhouses', 'routine serology on sow farms' and 'PCR on rendered animals'. The costs and benefits for applying the alternative surveillance-setup scenarios were evaluated by comparing the annual mitigated economic losses because of intensified CSF surveillance with the annual additional surveillance costs. The results of the cost-effectiveness analysis show that the alternative surveillance-setup scenarios with 'PCR on rendered animals' are effective for the moderately virulent CSF strain, whereas the scenarios with 'routine serology in slaughterhouses' or 'routine serology on sow farms' are effective for the low virulent strain. Moreover, the current CSF surveillance system in the Netherlands is cost-effective for both moderately virulent and low virulent CSF strains. The results of the cost-benefit analysis for the

  1. Potential use of school absenteeism record for disease surveillance in developing countries, case study in rural Cambodia.

    Directory of Open Access Journals (Sweden)

    Calvin K Y Cheng

    Full Text Available BACKGROUND: Disease surveillance allows prospective monitoring of patterns in disease incidence in the general community, specific institutions (e.g. hospitals, elderly care homes, and other important population subgroups. Surveillance activities are now routinely conducted in many developed countries and in certain easy-to-reach areas of the developing ones. However due to limited health resources, population in rural area that consisted of the most the vulnerable groups are not under surveillance. Cheaper alternative ways for disease surveillance were needed in resource-limited settings. METHODS AND FINDINGS: In this study, a syndromic surveillance system using disease specific absenteeism rates was established in 47 pre-schools with 1,417 students 3-6 y of age in a rural area of Kampot province, Cambodia. School absenteeism data were collected via short message service. Data collected between 1st January and 31st December 2012 was used for system evaluation for future potential use in larger scale. The system appeared to be feasible and acceptable in the rural study setting. Moderate correlation was found between rates of school absenteeism due to illness and the reference data on rates of attendance at health centers in persons <16 y (maximum cross-correlation coefficient = 0.231 at lag = -1 week. CONCLUSIONS: School absenteeism data is pre-existing, easily accessible and requires minimum time and resources after initial development, and our results suggest that this system may be able to provide complementary data for disease surveillance, especially in resource limited settings where there is very little information on illnesses in the community and traditional surveillance systems are difficult to implement. An important next step is to validate the syndromic data with other forms of surveillance including laboratory data.

  2. Syndromic surveillance and heat wave morbidity: a pilot study based on emergency departments in France

    2009-02-01

    Full Text Available Abstract Background The health impacts of heat waves are serious and have prompted the development of heat wave response plans. Even when they are efficient, these plans are developed to limit the health effects of heat waves. This study was designed to determine relevant indicators related to health effects of heat waves and to evaluate the ability of a syndromic surveillance system to monitor variations in the activity of emergency departments over time. The study uses data collected during the summer 2006 when a new heat wave occurred in France. Methods Data recorded from 49 emergency departments since July 2004, were transmitted daily via the Internet to the French Institute for Public Health Surveillance. Items collected on patients included diagnosis (ICD10 codes, outcome, and age. Statistical t-tests were used to compare, for several health conditions, the daily averages of patients within different age groups and periods (whether 'on alert' or 'off alert'. Results A limited number of adverse health conditions occurred more frequently during hot period: dehydration, hyperthermia, malaise, hyponatremia, renal colic, and renal failure. Over all health conditions, the total number of patients per day remained equal between the 'on alert' and 'off alert' periods (4,557.7/day vs. 4,511.2/day, but the number of elderly patients increased significantly during the 'on alert' period relative to the 'off alert' period (476.7/day vs. 446.2/day p Conclusion Our results show the interest to monitor specific indicators during hot periods and to focus surveillance efforts on the elderly. Syndromic surveillance allowed the collection of data in real time and the subsequent optimization of the response by public health agencies. This method of surveillance should therefore be considered as an essential part of efforts to prevent the health effects of heat waves.

    2016-05-01

    Full Text Available Cholera burden in Africa remains unknown, often because of weak national surveillance systems. We analyzed data from the African Cholera Surveillance Network (www.africhol.org.During June 2011-December 2013, we conducted enhanced surveillance in seven zones and four outbreak sites in Togo, the Democratic Republic of Congo (DRC, Guinea, Uganda, Mozambique and Cote d'Ivoire. All health facilities treating cholera cases were included. Cholera incidences were calculated using culture-confirmed cholera cases and culture-confirmed cholera cases corrected for lack of culture testing usually due to overwhelmed health systems and imperfect test sensitivity. Of 13,377 reported suspected cases, 34% occurred in Conakry, Guinea, 47% in Goma, DRC, and 19% in the remaining sites. From 0-40% of suspected cases were aged under five years and from 0.3-86% had rice water stools. Within surveillance zones, 0-37% of suspected cases had confirmed cholera compared to 27-38% during outbreaks. Annual confirmed incidence per 10,000 population was <0.5 in surveillance zones, except Goma where it was 4.6. Goma and Conakry had corrected incidences of 20.2 and 5.8 respectively, while the other zones a median of 0.3. During outbreaks, corrected incidence varied from 2.6 to 13.0. Case fatality ratios ranged from 0-10% (median, 1% by country.Across different African epidemiological contexts, substantial variation occurred in cholera incidence, age distribution, clinical presentation, culture confirmation, and testing frequency. These results can help guide preventive activities, including vaccine use.

    2011-09-01

    Full Text Available Abstract Background The establishment of robust biosurveillance capabilities is an important component of the U.S. strategy for identifying disease outbreaks, environmental exposures and bioterrorism events. Currently, U.S. Departments of Defense (DoD and Veterans Affairs (VA perform biosurveillance independently. This article describes a joint VA/DoD biosurveillance project at North Chicago-VA Medical Center (NC-VAMC. The Naval Health Clinics-Great Lakes facility physically merged with NC-VAMC beginning in 2006 with the full merger completed in October 2010 at which time all DoD care and medical personnel had relocated to the expanded and remodeled NC-VAMC campus and the combined facility was renamed the Lovell Federal Health Care Center (FHCC. The goal of this study was to evaluate disease surveillance using a biosurveillance application which combined data from both populations. Methods A retrospective analysis of NC-VAMC/Lovell FHCC and other Chicago-area VAMC data was performed using the ESSENCE biosurveillance system, including one infectious disease outbreak (Salmonella/Taste of Chicago-July 2007 and one weather event (Heat Wave-July 2006. Influenza-like-illness (ILI data from these same facilities was compared with CDC/Illinois Sentinel Provider and Cook County ESSENCE data for 2007-2008. Results Following consolidation of VA and DoD facilities in North Chicago, median number of visits more than doubled, median patient age dropped and proportion of females rose significantly in comparison with the pre-merger NC-VAMC facility. A high-level gastrointestinal alert was detected in July 2007, but only low-level alerts at other Chicago-area VAMCs. Heat-injury alerts were triggered for the merged facility in June 2006, but not at the other facilities. There was also limited evidence in these events that surveillance of the combined population provided utility above and beyond the VA-only and DoD-only components. Recorded ILI activity for NC

    There is very little data pertaining to cerebral palsy (CP) from Nepal. In this retrospective study it was observed that dyskinetic CP was seen in 29 % and the sex ratio of males to females was two in the study population of children with CP. Both of these are much higher than data from developed countries. Hence, further randomized cross-sectional community based study is recommended to enquire into this pattern. Data regarding early identification was encouraging as majority of the cases (56 %) were diagnosed before 4 years of age. There is a stark necessity of early screening and rehabilitation program with provision for follow-up for the affected children, which must also be accessible to the disadvantaged and marginalized groups in Nepal.

    Full Text Available Abstract Background Nausea and vomiting is a problem for children after neurosurgery and those requiring posterior fossa procedures appear to have a high incidence. This clinical observation has not been quantified nor have risk factors unique to this group of children been elucidated. Methods A six year retrospective chart audit at two Canadian children's hospitals was conducted. The incidence of nausea and vomiting was extracted. Hierarchical multivariable logistic regression was used to quantify risk and protective factors at 120 hours after surgery and early vs. late vomiting. Results The incidence of vomiting over a ten day postoperative period was 76.7%. Documented vomiting ranged from single events to greater than 20 over the same period. In the final multivariable model: adolescents (age 12 to Conclusion The incidence of vomiting in children after posterior fossa surgery is sufficient to consider all children requiring these procedures to be at high risk for POV. Nausea requires better assessment and documentation.

  9. Retrospective audit of patients presenting to our department for venoscintigraphy

    International Nuclear Information System (INIS)

    Objective: Though a number of studies have attempted to list the risk factors for DVT, there seems to be paucity of information relating to patients in Africa. We realized that a number of patients referred to our department for venoscintigraphy have concomitant tuberculosis and retroviral disease. Therefore, we decided to assess the possible relationship between DVT and the above-mentioned concomitant diseases. Method: A retrospective study of all patients referred for venous scintigraphy of the lower limbs in 2003 was done. Data from 160 patients was available for analysis. We looked at patient age and gender as well as the incidence of concurrent tuberculosis and retro-viral disease. The results are presented in a table. The remaining patients have shown either chronic venous disease or equivocal results. Conclusion: Tuberculosis and retroviral disease may be contributing risk factors in our population. (author)

    Full Text Available Background: Multicystic dysplastic kidney (MCDK is one of the most frequently observed congenital urinary tract abnormalities. Methods: Retrospective study of MCDK in nephrectomy specimens seen over a 20 year period at a tertiary care teaching hospital in South India. Results: MCDK was evident in 6 of the 230 nephrectomy specimens (2.6% seen during the 20 year period of study. Their median age [interquartile range (IQR] was 2.25 (1.075-7.750 years; there were 3 males. MCDK more frequently involved the right kidney (5/6; 4 cases presented with megaureter. Salient histopathological findings included cystically dilated spaces lined by flattened to cuboidal lining epithelium with intervening stroma showing entrapped, dilated, narrowed immature tubules with surrounding smooth muscle cuffing. Conclusions: Histopathological examination remains the mainstay in the diagnosis and helps in differentiating MCDK from other cystic lesions.

    This work is a retrospective study of latrodectism in the State of Bahia, Brazil, from August 1980 to July 1990. The data concerning the accidents were obtained from file cards at the Antivenom Information Center of Bahia (AVICB). Latrodectus curacavienis was the ethiologic agent identified in 28% of the arachnid accidents. The major incidence was registered in urban area (57%) affecting men (70%) more than women, with 10 to 29 year-old age group (58%). Local pain (56%), erythematous papula (29%) and light oedema (17%) were the principal local symptoms. Pain in the limbs (29%), tremor and rigidities (29%), sweating (28%), limbs and arms paresthesia (21%) and abdominal pain (17%) were systemic ones. The treatment was mainly symptomatic (67%) and antivenin serum was used in 21% of the cases. After serotherapy, 64% of the patients left the hospital within less than 24 hours. PMID:7480914

    2015-01-01

    Background Acute poisoning is one of the most common reasons for emergency department visits around the world. In Pakistan, the epidemiological data on poisoning is limited due to an under developed poison information surveillance system. We aim to describe the characteristics associated with intentional and unintentional poisoning in Pakistan presenting to emergency departments. Methods The data was extracted from the Pakistan National Emergency Department Surveillance (Pak-NEDS) which was an active surveillance conducted between November 2010 and March 2011. All patients, regardless of age, who presented with poisoning to any of Pakistan's seven major tertiary care centers' emergency departments, were included. Information about patient demographics, type of poisoning agent, reason for poisoning and outcomes were collected using a standard questionnaire. Results Acute poisoning contributed to 1.2% (n = 233) of patients with intentional and unintentional injuries presenting to EDs of participating centers. Of these, 68% were male, 54% were aged 19 to 44 and 19% were children and adolescents (drug/medicine (27%), alcohol (16.7%) and food/plant (6%). In half of all patients the poisoning was intentional. A total of 11.6% of the patients were admitted and 6.6% died. Conclusion Poisoning causes more morbidity and mortality in young adults in Pakistan compared to other age groups, half of which is intentional. Improving mental health, regulatory control for hazardous chemicals and better access to care through poison information centers and emergency departments will potentially help control the problem.

    Full Text Available Introduction: Silicosis in Coimbatore district of Tamil Nadu: A passive surveillance study. Aim: This study was done to describe the level of preventive measures and level of awareness among the patients diagnosed with silicosis during a one-year period. Settings and Design: Coimbatore Medical College Hospital. Materials and Methods: This is a passive surveillance study based on patients diagnosed with silicosis in our outpatient facility for a one-year period between January 1, 2012 and December 31, 2012. Results: Seventeen cases of silicosis were diagnosed based on history of exposure to silica and radiological features. The mean age was 55 years with 16 males and one female. The average duration of exposure was 22 years. A protective mask was used by 29% of the patients and one patient had awareness about the risks of exposure to silica. Active tuberculosis was found in 12% and old tuberculosis in 47% of patients; 59% of the patients were smokers. Spirometry showed a restrictive pattern in 59% of the patients. Radiologically nodular opacities with upper-zone predominance was found in majority of the cases. Conclusion: Most patients are exposed to silica in unorganized industries. Majority of the patients lack awareness about the disease and there is a low implementation of preventive and control measures. As this study was a passive surveillance, it represents only the tip of iceberg and an active field-level surveillance could reveal the true prevalence of this disease.

    Female BRCA1/BRCA2 mutation carriers are at substantially increased risk for developing breast and/or ovarian cancer, and are offered enhanced surveillance including screening from a young age and risk-reducing surgery (RRS)-mastectomy (RRM) and/or salpingo-oophorectomy (RRSO). While there are established guidelines for early detection of breast cancer in high-risk women who have not undergone RRM, there are less developed guidelines after RRM. We evaluated the schemes offered before and after RRS in internationally diverse high-risk clinics. An e-mailed survey was distributed to high-risk clinics affiliated with CIMBA. Overall, 22 centers from 16 countries responded. Pre RRS surveillance schemes overwhelmingly included breast imaging (primarily MRI) from 18 to 30 years and clinical breast exam (CBE) at 6-12 month intervals. For ovarian cancer, all but 6 centers offered semiannual/annual gynecological exam, transvaginal ultrasound, and CA 125 measurements. Post RRM, most centers offered only annual CBE while 4 centers offered annual MRI, primarily for substantial residual breast tissue. After RRSO only 4 centers offered specific gynecological surveillance. Existing guidelines for breast/ovarian cancer detection in BRCA carriers are being applied pre RRS but are not globally harmonized, and most centers offer no specific surveillance post RRS. From this comprehensive multinational study it is clear that evidence-based, long-term prospective data on the most effective scheme for BRCA carriers post RRS is needed. PMID:27117159

    Full Text Available Abstract Background Endoscopic band ligation (EBL is generally accepted as the treatment of choice for bleeding from esophageal varices. It is also used for secondary prophylaxis of esophageal variceal hemorrhage. However, there is no data or guidelines concerning endoscopic control of ligation ulcers. We conducted a retrospective study of EBL procedures analyzing bleeding complications after EBL. Methods We retrospectively analyzed data from patients who underwent EBL. We analyzed several data points, including indication for the procedure, bleeding events and the time interval between EBL and bleeding. Results 255 patients and 387 ligation sessions were included in the analysis. We observed an overall bleeding rate after EBL of 7.8%. Bleeding events after elective treatment (3.9% were significantly lower than those after treatment for acute variceal hemorrhage (12.1%. The number of bleeding events from ligation ulcers and variceal rebleeding was 14 and 15, respectively. The bleeding rate from the ligation site in the group who underwent emergency ligation was 7.1% and 0.5% in the group who underwent elective ligation. Incidence of variceal rebleeding did not vary significantly. Seventy-five percent of all bleeding episodes after elective treatment occurred within four days after EBL. 20/22 of bleeding events after emergency ligation occured within 11 days after treatment. Elective EBL has a lower risk of bleeding from treatment-induced ulceration than emergency ligation. Conclusions Patients who underwent EBL for treatment of acute variceal bleeding should be kept under medical surveillance for 11 days. After elective EBL, it may be reasonable to restrict the period of surveillance to four days or even perform the procedure in an out-patient setting.

  18. Surveyor mobile surveillance system for hazardous environments

    International Nuclear Information System (INIS)

    A successful program was recently conducted to test and evaluate a commercial-ready, wireless, remotely operated surveillance system for use in nuclear power plants. This evaluation of the Surveyor mobile surveillance system took place at Niagara Mohawk Power Corporation's Nine Mile Point Nuclear Power Station. The remotely operated vehicle measures radiation, temperature and relative humidity and provides optical inspection capability. The vehicle is readily maneuvered in 36-inch wide passageways and labyrinth entries and can climb stairs, negotiating 180-degree turns on stair landings. The system consists of a supervisory control station and a rugged, remotely-operated, battery-powered vehicle. The surveyor system is specifically designed to decrease personnel radiation exposure by supplementing the functions of an auxiliary operator or wealth physics technician to perform periodic component inspections inside particular areas within a nuclear power plant

    In modern technologically advanced societies citizens leave numerous identifiable digital traces that are being stored, monitored and processed by both private and public parties. This has led to what is commonly called a 'surveillance society'. Increasingly, this abundance of (personal information is also being used to influence and control people. The active, deliberate, large scale control of people in their private lives is seen here as a key characteristic of a totalitarian society. The question (and also the concern arises whether the gradual move to a surveillance society will be followed by a (gradual move to a totalitarian society. The issues presented by the author are illustrated by several examples, with a focus on the technologies involved.

  20. Laser surveillance system for spent fuel

    International Nuclear Information System (INIS)

    A laser surveillance system installed at spent fuel storage pools will provide the safeguard inspector with specific knowledge of spent fuel movement that cannot be obtained with current surveillance systems. The laser system will allow for the division of the pool's spent fuel inventory into two populations - those assemblies which have been moved and those which haven't - which is essential for maximizing the efficiency and effectiveness of the inspection effort. We have designed, constructed, and tested a laser system and have used it with a simulated BWR assembly. The reflected signal from the zircaloy rods depends on the position of the assembly, but in all cases is easily discernable from the reference scan of background with no assembly
