    In 1979, continuing care from a personal physician was identified as a priority at the Indian Health Service site in Zuni, NM, a rural hospital and ambulatory care center serving 7,000 Zuni people. To encourage such care, a system was established that assigned each patient to a regular physician and organized physicians into teams. Three teams, each consisting of three clinicians and other support personnel, served specific geographic regions of the village. Five years later, the ongoing care provided for active randomly selected prenatal, diabetic, and general clinic patients was evaluated. The physician staff of the site had gone through a complete turnover during the previous five years. Based on a chart review for the year prior to patient identification, patients saw their regular physician from 48 to 61 percent of the time in all their visits, and their regular physician or his or her team colleague from 71 to 82 percent of the time in all their visits. Ongoing care from a personal physician or close colleague can be achieved in the Indian Health Service. Organization of physicians into teams appeared to be the critical element in promoting ongoing care at this site where physician turnover is high. Team physicians seldom all leave at once, and ongoing care as a priority is passed on by the attitude of other team physicians, by transfer of specific patients, and by patient expectation. Given the established benefits, ongoing care from a personal provider should be encouraged in the Indian Health Service as in other primary care settings. PMID:3083473

    The constraints on the time variation of the fine structure constant at recombination epoch relative to its present value, Δα/α ≡ (α_{rec} - α_{now})/α_{now}, are obtained from the analysis of the 5-year WMAP cosmic microwave background data. As a result of Markov-Chain Monte-Carlo analysis, it is found that, contrary to the analysis based on the previous WMAP data, the mean value of Δα/α = -0.0009 does not change significantly whether we use the Hubble Space Telescope (HST) measurement of the Hubble parameter as a prior or not. The resultant 95% confidence ranges of Δα/α are -0.028 < Δα/α < 0.026 with HST prior and -0.050 < Δα/α < 0.042 without HST prior.

    We investigated the effects of the duration and type of to-be-articulated distractors during encoding of a verbal list into short-term memory (STM). Distractors and to-be-remembered items alternated during list presentation, as in the complex-span task that underlies much of working-memory research. According to an interference model of STM, known as serial order in a box (SOB; Farrell & Lewandowsky, 2002), additional repeated articulations of the same word between list items should cause minimal further disruption of encoding into STM even though the retention interval for early list items is increased. SOB also predicts that the articulation of several different distractor items should lead to much enhanced disruption if the distractor interval is increased. Those predictions were qualitatively confirmed in 4 experiments that found that it is the type of distractors, not their total duration, that determines the success of encoding a list into STM. The results pose a challenge to temporal models of complex-span performance, such as the time-based resource sharing model (Barrouillet, Bernardin, & Camos, 2004). The results add to a growing body of evidence that memory for the short term is not exclusively governed by purely temporal processes. PMID:20565212

    Experienced meditators typically report that they experience time slowing down in meditation practice as well as in everyday life. Conceptually this phenomenon may be understood through functional states of mindfulness, i.e., by attention regulation, body awareness, emotion regulation, and enhanced memory. However, hardly any systematic empirical work exists regarding the experience of time in meditators. In the current cross-sectional study, we investigated whether 42 experienced mindfulness meditation practitioners (with on average 10 years of experience) showed differences in the experience of time as compared to 42 controls without any meditation experience matched for age, sex, and education. The perception of time was assessed with a battery of psychophysical tasks assessing the accuracy of prospective time judgments in duration discrimination, duration reproduction, and time estimation in the milliseconds to minutes range as well with several psychometric instruments related to subjective time such as the Zimbardo Time Perspective Inventory, the Barratt Impulsivity Scale and the Freiburg Mindfulness Inventory. In addition, subjective time judgments on the current passage of time and retrospective time ranges were assessed. While subjective judgements of time were found to be significantly different between the two groups on several scales, no differences in duration estimates in the psychophysical tasks were detected. Regarding subjective time, mindfulness meditators experienced less time pressure, more time dilation, and a general slower passage of time. Moreover, they felt that the last week and the last month passed more slowly. Overall, although no intergroup differences in psychophysical tasks were detected, the reported findings demonstrate a close association between mindfulness meditation and the subjective feeling of the passage of time captured by psychometric instruments.

    We empirically investigate the distribution of time spans between price maxima and price minima in international stock markets, where a time span is defined as the time interval between a local price minimum and a local price maximum, and local price extrema are identified by a method introduced by Preis and Stanley (Preis et al. (2011), Preis (2011), Preis and Stanley (2011, 2010), Preis (2010), Preis and Stanley (2010), Stanley et al. (2010), Preis and Stanley (2009)). The empirical results show that both the tail distributions of time spans from local price maxima to local price minima and the tail distributions of time spans from local price minima to local price maxima yield an exponential distribution. In addition, price rise/fall asymmetry is observed by comparing the values of the exponents of the distribution curves. These results are robust across eight representative stock markets.

    Introduction The global increase in childhood overweight and obesity has been ascribed partly to increases in children's screen time. Parents have a large influence on their children's screen time. Studies investigating parenting and early childhood screen time are limited. In this study, we investigated associations of parenting style and the social and physical home environment on watching TV and using computers or game consoles among 5-year-old children. Methods This study uses baseline data concerning 5-year-old children (n = 3067) collected for the ‘Be active, eat right’ study. Results Children of parents with a higher score on the parenting style dimension involvement, were more likely to spend >30 min/day on computers or game consoles. Overall, families with an authoritative or authoritarian parenting style had lower percentages of children's screen time compared to families with an indulgent or neglectful style, but no significant difference in OR was found. In families with rules about screen time, children were less likely to watch TV>2 hrs/day and more likely to spend >30 min/day on computers or game consoles. The number of TVs and computers or game consoles in the household was positively associated with screen time, and children with a TV or computer or game console in their bedroom were more likely to watch TV>2 hrs/day or spend >30 min/day on computers or game consoles. Conclusion The magnitude of the association between parenting style and screen time of 5-year-olds was found to be relatively modest. The associations found between the social and physical environment and children's screen time are independent of parenting style. Interventions to reduce children's screen time might be most effective when they support parents specifically with introducing family rules related to screen time and prevent the presence of a TV or computer or game console in the child's room.

  9. A Linear Time Algorithm for the Minimum Spanning Caterpillar Problem for Bounded Treewidth Graphs

    Dinneen, Michael J.; Khosravani, Masoud

    We consider the Minimum Spanning Caterpillar Problem (MSCP) in a graph where each edge has two costs, spine (path) cost and leaf cost, depending on whether it is used as a spine or a leaf edge. The goal is to find a spanning caterpillar in which the sum of its edge costs is the minimum. We show that the problem has a linear time algorithm when a tree decomposition of the graph is given as part of the input. Despite the fast growing constant factor of the time complexity of our algorithm, it is still practical and efficient for some classes of graphs, such as outerplanar, series-parallel (K 4 minor-free), and Halin graphs. We also briefly explain how one can modify our algorithm to solve the Minimum Spanning Ring Star and the Dual Cost Minimum Spanning Tree Problems.

    Life expectancy has increased continuously for at least 150 years, due at least in part to improving life conditions for the majority of the population. A substantial part of this historical increase is due to decreases in early life mortality. In this article, we analyze the longevity of four privileged sets of adults who have avoided childhood mortality and lived a life more similar to the modern middle class. Our analysis is focused on writers and musicians from the 17th through the 21st centuries. We show that their average age at death increased only slightly between 1600 and 1900, but in the 20th century increased at around 2 years/decade. We suggest that this confirms that modern life span extension is driven by delay of death in older life rather than avoidance of premature death. We also show that productive life span, as measured by writing and composition outputs, has increased in parallel with overall life span in these groups. Increase in age of death is confirmed in a group of the minor British aristocracy and in members of the US Congress from 1800 to 2010. We conclude that both life span and productive life span are increasing in the 20th and early 21st century, and that the modern prolongation of life is the extension of productive life and is not the addition of years of disabling illness to the end of life.

    We present TimeSpan, an exploratory visualization tool designed to gain a better understanding of the temporal aspects of the stroke treatment process. Working with stroke experts, we seek to provide a tool to help improve outcomes for stroke victims. Time is of critical importance in the treatment of acute ischemic stroke patients. Every minute that the artery stays blocked, an estimated 1.9 million neurons and 12 km of myelinated axons are destroyed. Consequently, there is a critical need for efficiency of stroke treatment processes. Optimizing time to treatment requires a deep understanding of interval times. Stroke health care professionals must analyze the impact of procedures, events, and patient attributes on time-ultimately, to save lives and improve quality of life after stroke. First, we interviewed eight domain experts, and closely collaborated with two of them to inform the design of TimeSpan. We classify the analytical tasks which a visualization tool should support and extract design goals from the interviews and field observations. Based on these tasks and the understanding gained from the collaboration, we designed TimeSpan, a web-based tool for exploring multi-dimensional and temporal stroke data. We describe how TimeSpan incorporates factors from stacked bar graphs, line charts, histograms, and a matrix visualization to create an interactive hybrid view of temporal data. From feedback collected from domain experts in a focus group session, we reflect on the lessons we learned from abstracting the tasks and iteratively designing TimeSpan. PMID:26390482

    This paper studies the critical time span and the approximate nonlinear action structure of climatic atmosphere and ocean. The critical time span of the climatic atmosphere and ocean, which is related to the spatial resolution required, the strength of nonlinear action, and the calculation exactness, may represent the relative temporal scale of predictability. As far as the same characteristic spatial scale is concerned, the minimum critical time span of the ocean is about 9 times of that of atmosphere, several days or more. Usually, the stronger the nonlinear action, the shorter the critical time span with smooth changes of external forces. The approximate structure of nonlinear action of climatic atmosphere and ocean is: the nonlinear action decreases usually with increasing latitude, which is related to the role of the Coriolis force in fluid motion (forming geostrophic current); the nonlinear action changes with the anomalous cyclonic or anticyclonic circulation shear, for instance, when the strength of anomalous eastward zonal circulation is comparable to that of anomalous meridional circulation, the nonlinear action is the strongest; wind stress plus gradient forces enhance the nonlinear action, etc..

    The flight performance of animals depends greatly on the efficacy with which they generate aerodynamic forces. Accordingly, maximum range, load-lifting capacity and peak accelerations during manoeuvres are all constrained by the efficiency of momentum transfer to the wake. Here, we use high-speed particle image velocimetry (1 kHz) to record flow velocities in the near wake of desert locusts (Schistocerca gregaria, Forskål). We use the measured flow fields to calculate time-varying span efficiency throughout the wing stroke cycle. The locusts are found to operate at a maximum span efficiency of 79 per cent, typically at a plateau of about 60 per cent for the majority of the downstroke, but at lower values during the upstroke. Moreover, the calculated span efficiencies are highest when the largest lift forces are being generated (90% of the total lift is generated during the plateau of span efficiency) suggesting that the combination of wing kinematics and morphology in locust flight perform most efficiently when doing the most work.

    Background The use of combination antiretroviral therapy (cART) comprising three antiretroviral medications from at least two classes of drugs is the current standard treatment for HIV infection in adults and children. Current World Health Organization (WHO) guidelines for antiretroviral therapy recommend early treatment regardless of immunologic thresholds or the clinical condition for all infants (less than one years of age) and children under the age of two years. For children aged two to five years current WHO guidelines recommend (based on low quality evidence) that clinical and immunological thresholds be used to identify those who need to start cART (advanced clinical stage or CD4 counts ≤ 750 cells/mm3 or per cent CD4 ≤ 25%). This Cochrane review will inform the current available evidence regarding the optimal time for treatment initiation in children aged two to five years with the goal of informing the revision of WHO 2013 recommendations on when to initiate cART in children. Objectives To assess the evidence for the optimal time to initiate cART in treatment-naive, HIV-infected children aged 2 to 5 years. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the AEGIS conference database, specific relevant conferences, www.clinicaltrials.gov, the World Health Organization International Clinical Trials Registry platform and reference lists of articles. The date of the most recent search was 30 September 2012. Selection criteria Randomised controlled trials (RCTs) that compared immediate with deferred initiation of cART, and prospective cohort studies which followed children from enrolment to start of cART and on cART. Data collection and analysis Two review authors considered studies for inclusion in the review, assessed the risk of bias, and extracted data on the primary outcome of death from all causes and several secondary outcomes, including incidence of CDC category C and B clinical events and

    We report on the extensive multi-wavelength observations of the blazar Markarian 421 (Mrk 421) covering radio to γ-rays, during the 4.5 year period of ARGO-YBJ and Fermi common operation time, from 2008 August to 2013 February. These long-term observations, extending over an energy range of 18 orders of magnitude, provide a unique chance to study the variable emission of Mrk 421. In particular, due to the ARGO-YBJ and Fermi data, the entire energy range from 100 MeV to 10 TeV is covered without any gap. In the observation period, Mrk 421 showed both low- and high-activity states at all wavebands. The correlations among flux variations in different wavebands were analyzed. The X-ray flux is clearly correlated with the TeV γ-ray flux, while the GeV γ-rays only show a partial correlation with the TeV γ-rays. Radio and UV fluxes seem to be weakly or not correlated with the X-ray and γ-ray fluxes. Seven large flares, including five X-ray flares and two GeV γ-ray flares with variable durations (3-58 days), and one X-ray outburst phase were identified and used to investigate the variation of the spectral energy distribution with respect to a relative quiescent phase. During the outburst phase and the seven flaring episodes, the peak energy in X-rays is observed to increase from sub-keV to a few keV. The TeV γ-ray flux increases up to 0.9-7.2 times the flux of the Crab Nebula. The behavior of GeV γ-rays is found to vary depending on the flare, a feature that leads us to classify flares into three groups according to the GeV flux variation. Finally, the one-zone synchrotron self-Compton model was adopted to describe the emission spectra. Two out of three groups can be satisfactorily described using injected electrons with a power-law spectral index around 2.2, as expected from relativistic diffuse shock acceleration, whereas the remaining group requires a harder injected spectrum. The underlying physical mechanisms responsible for different groups may be related to

    The aim of this study was to compare safety and efficacy of bambuterol hydrochloride (10 mg) oral solution administered once daily in the evening with terbutaline sulphate (0.075 mg/kg body weight) oral solution administered three times daily in 2-5-year-old children with asthma. There were two treatment groups: (2/3) of the patients received bambuterol and (1/3) received terbutaline. The study was double-blind, randomized, and of a parallel group design, and it lasted for 3 months after a 2-week run-in period. The primary objective was to evaluate safety (adverse events, and changes in blood pressure, pulse rate, hematology, and clinical chemistry parameters). Plasma concentrations of terbutaline and/or bambuterol were also measured. Evaluation of efficacy (diary card data) was a secondary objective. A total of 155 patients (range, 2-6 years; 3 patients were 6 years old at randomization) were treated with the study drugs; 104 patients received bambuterol and 51 patients received terbutaline. Both treatments showed a good safety profile with respect to clinical and laboratory tests, and they were generally well tolerated. Reported adverse events were mild to moderate. There were no statistically significant differences between treatment groups in any of the efficacy variables (diary variables: peak expiratory flow (PEF), asthma symptoms, restlessness, other reported symptoms, use of inhaled bronchodilators, and nighttime awakenings). For morning PEF, the mean increase from run-in to treatment was 16.9 L/min in the terbutaline group and 23.3 L/min in the bambuterol group. For evening PEF, the mean increase was 20.2 L/min in the terbutaline group and 20.6 L/min in the bambuterol group. In conclusion, once-daily bambuterol is as safe and effective as terbutaline given three times daily. The study also confirmed that bambuterol has a 24-hr duration of action, and therefore its once daily administration, makes it a preferred bronchodilator agent. Pediatr Pulmonol. 2000

  19. Phase synchronization based minimum spanning trees for analysis of financial time series with nonlinear correlations

    The cross correlation coefficient has been widely applied in financial time series analysis, in specific, for understanding chaotic behaviour in terms of stock price and index movements during crisis periods. To better understand time series correlation dynamics, the cross correlation matrices are represented as networks, in which a node stands for an individual time series and a link indicates cross correlation between a pair of nodes. These networks are converted into simpler trees using different schemes. In this context, Minimum Spanning Trees (MST) are the most favoured tree structures because of their ability to preserve all the nodes and thereby retain essential information imbued in the network. Although cross correlations underlying MSTs capture essential information, they do not faithfully capture dynamic behaviour embedded in the time series data of financial systems because cross correlation is a reliable measure only if the relationship between the time series is linear. To address the issue, this work investigates a new measure called phase synchronization (PS) for establishing correlations among different time series which relate to one another, linearly or nonlinearly. In this approach the strength of a link between a pair of time series (nodes) is determined by the level of phase synchronization between them. We compare the performance of phase synchronization based MST with cross correlation based MST along selected network measures across temporal frame that includes economically good and crisis periods. We observe agreement in the directionality of the results across these two methods. They show similar trends, upward or downward, when comparing selected network measures. Though both the methods give similar trends, the phase synchronization based MST is a more reliable representation of the dynamic behaviour of financial systems than the cross correlation based MST because of the former's ability to quantify nonlinear relationships among time

  2. Insights into the dynamics of Etna volcano from 20-year time span microgravity and GPS observations

    A common ground deformation and microgravity array of benchmarks lies on the southern slope of Mt. Etna volcano and is routinely measured by GPS and relative gravimetry methods. The array was installed for monitoring the ground motion and underground mass changes along the southern rift of the volcano and data are usually processed and interpreted independently. The benchmarks have been installed mainly along a main road crossing the southern side of the volcano with an E-W direction and reaching 2000 m of altitude. The gravity array covers the entire path of the road, while the ground deformation one only the upper one, due to the woods at lower altitude preventing good GPS measurements. Furthermore, microgravity surveys are usually carried out more frequently with respect to the GPS ones. In this work, an integrated analysis of microgravity and ground deformation is performed over a 20-year time span (1994-2014). Gravity variations have been first corrected for the free-air effect using the GPS observed vertical deformation and the theoretical vertical gravity gradient (-308.6 μGal/m). The free-air corrected gravity changes were then reduced from the high frequency variations (noise) and the seasonal fluctuations, mainly due to water-table fluctuations. This long-term dataset constitutes a unique opportunity to examine the behavior of Etna in a period in which the volcano exhibited different styles of activity characterized by recharging phases, flank eruptions and fountaining episodes. The gravity and deformation data allow investigating the response of the volcano in a wider perspective providing insights into the definition of its dynamic behavior and posing the basis to track the unrest evolution and to forecast the style of the eruption. The joint analysis highlights common periods, in which the signals underwent contemporaneous changes occurring mainly in the central and eastern stations. On the other hand, no significant changes in the behavior of

    It is, by now, well established that mold toxins (mycotoxins) can cause significant adverse health effects. In this study, 15 subjects who developed an attention deficit disorder (ADD) and slowing of reaction time at the time of exposure to mold toxins were identified. Deficits in attention span and reaction time were documented not only by taking a careful history, but also by performing a Test of Variables of Attention (TOVA). The TOVA test provides an objective measure of these two variables. It was found that mold-exposed subjects show statistically significant decreases in attention span and significant increases in reaction time to stimuli compared to controls. After ten sessions of hyperbaric oxygen treatment (HBOT), a statistically significant improvement was seen in both measures. This preliminary study suggests promising outcomes in treating mold-exposed patients with hyperbaric oxygen. PMID:20978814

    According to socioemotional selectivity theory, older adults' emotional well-being stems from having a limited future time perspective that motivates them to maximize well-being in the "here and now." Presumably, then, older adults' time horizons are associated with emotional competencies that boost positive affect and dampen negative affect, but little research has addressed this. Using a U.S. adult life-span sample (N = 3,933; 18-93 years), we found that a 2-factor model of future time perspective (future opportunities; limited time) fit the data better than a 1-factor model. Through middle age, people perceived the life-span hourglass as half full-they focused more on future opportunities than limited time. Around Age 60, the balance changed to increasingly perceiving the life-span hourglass as half empty-they focused less on future opportunities and more on limited time, even after accounting for perceived health, self-reported decision-making ability, and retirement status. At all ages, women's time horizons focused more on future opportunities compared with men's, and men's focused more on limited time. Focusing on future opportunities was associated with reporting less preoccupation with negative events, whereas focusing on limited time was associated with reporting more preoccupation. Older adults reported less preoccupation with negative events, and this association was stronger after controlling for their perceptions of limited time and fewer future opportunities, suggesting that other pathways may explain older adults' reports of their ability to disengage from negative events. Insights gained and questions raised by measuring future time perspective as 2 dimensions are discussed. (PsycINFO Database Record PMID:27267222

    We have developed a clinically ready first generation stationary breast tomosynthesis system (s-DBT). In the s-DBT system, focal spot blur associated with x-ray source motion is completely eliminated, allowing for rapid acquisition of projection images over a larger angular span without changing the acquisition time. In the phantom studies the 1st generation s-DBT system has demonstrated 30% higher spatial resolution than the corresponding continuous motion DBT systems. The system is currently being evaluated for its diagnostic performance in 100 patient clinical evaluation against FFDM. Initial results indicate that the s­-DBT system can produce increased lesion conspicuity and comparable MC visibility. However due to x­-ray flux limitations, certain large size patients have to be excluded. Recent studies have shown that increasing the angular span beyond 30° can be beneficial for enhanced depth resolution. We report the preliminary characterization of the 2nd generation s-­DBT system with a new CNT x-­ray source array, increased tube flux and a larger angular span. Increasing x-ray tube flux allows for a larger patient population and dual energy imaging. Results indicate that the system delivers more than twice the flux, allowing for imaging of all size patients with acquisition time of 2­-4 seconds. A 7° increase in angular span over 1st generation decreased the ASF by 37%. Additionally, the 2nd generation s-DBT system utilizing a specific AFVR reconstruction method resulted in a 92% increase in the in plane resolution over CM DBT system, and a 37% increase in spatial resolution over the 1st generation s--DBT system.

    In this paper, we present simultaneous transmission of accurate time and stable frequency over 306 km long fiber link. The fiber link belongs to the Time and Frequency infrastructure that is being gradually developed and which shares fiber footprint with data network. The link had been originally deployed with wavelength division multiplexing systems for C and L band systems. But it has been recently upgraded to support 800 GHz wide super-channel with single signal path for both directions. This bidirectional super-channel spans over two extensive segments with attenuation of 28 and 25 dB.

    IR detector Dewars commonly suffer from shorter than desired LN2 hold times and insulation jacket vacuum corruption over relatively short time periods. In an attempt to solve this problem for a 9144 detector Dewar, small 1 liter/s appendage ion pumps were selected for continuous pumping of the vacuum jackets. This procedure extended LN2 hold times from 20 to 60 h and virtually eliminated vacuum jacket corruption. Thus the detector systems are usable continuously over periods of 6 months or more.

    A new mathematical model was used to analyze a detailed set of human immunodeficiency virus-type 1 (HIV-1) viral load data collected from five infected individuals after the administration of a potent inhibitor of HIV-1 protease. Productively infected cells were estimated to have, on average, a life-span of 2.2 days (half-life t{sub 1/2} = 1.6 days), and plasma virions were estimated to have, on average, a mean life-span of 0.3 days (t{sub 1/2} = 0.24 days). The estimated average total HIV-1 production was 10.3 x 10{sup 9}virions per day, which is substantially greater than previous minimum estimates. The results also suggest that the minimum duration of the HIV-1 life cycle in vivo is 1.2 days on average, and that the average HIV-1 generation time-defined as the time from release of a virion until it infects another cell and causes the release of a new generation of viral particles-is 2.6 days. These findings on viral dynamics provide not only a kinetic picture of HIV-1 pathogenesis, but also theoretical principles to guide the development of treatment strategies. 22 refs., 1 fig., 2 tabs.

    Two sets of experiments were run to examine how the mental workload of a pilot might be measured. The effects of continuous manual control activity versus discrete assigned mental tasks (including the length of time between receiving an assignment and executing it) were examined. The first experiment evaluated the strengths and weaknesses of measuring mental workload with an objective perforamance (altitude deviations) and five subjective ratings (activity level, complexity, difficulty, stress, and workload). The second set of experiments built upon the first set by increasing workload intensities and adding another performance measure: airspeed deviation. The results are discussed for both low and high experience pilots.

    The variability of the blazar Markarian 421 in TeV gamma rays over a 14-year time period has been explored with theWhipple 10 m telescope. It is shown that the dynamic range of its flux variations is large and similar to that in X-rays. A correlation between the X-ray and TeV energy bands is observed during some bright flares and when the complete data sets are binned on long timescales. The main database consists of 878.4 hours of observation with theWhipple telescope, spread over 783 nights. The peak energy response of the telescope was 400 GeV with 20% uncertainty. This is the largest database of any TeV-emitting active galactic nucleus (AGN) and hence was used to explore the variability profile of Markarian 421. The time-averaged flux from Markarian 421 over this period was 0.446+/-0.008 Crab flux units. The flux exceeded 10 Crab flux units on three separate occasions. For the 2000-2001 season the average flux reached 1.86 Crab units, while in the 1996-1997 season the average flux was only 0.23 Crab units.

    Two sets of simulations designed to examine how a pilot's mental workload is affected by continuous manual-control activity versus discrete mental tasks that included the length of time between receiving an assignment and executing it are described. The first experiment evaluated two types of measures: objective performance indicators and subjective ratings. Subjective ratings for the two missions were different, but the objective performance measures were similar. In the second experiments, workload levels were increased and a second performance measure was taken. Mental workload had no influence on either performance-based workload measure. Subjective ratings discriminated among the scenarios and correlated with performance measures for high-workload flights. The number of mental tasks performed did not influence error rates, although high manual workloads did increase errors.

    There is considerable evidence showing that night work is associated with increased morbidity, but only a few studies have focused on its relation to mortality. This study investigates the relationship between the type of working-time arrangement (weekly night work/daytime work) and total and cause-specific mortality among men and women. The data consist of a representative working conditions survey of Finnish employees conducted in 1984 (2286 men/2216 women), which has been combined with register-based follow-up data from Statistics Finland covering the years 1985-2008. In the 1984 survey, the employees were asked if they worked during the night (23:00-06:00 h) and if so, how often. In this study, the authors compare employees who worked at night (121 men/89 women) to daytime employees who did not do night work (1325 men/1560 women). The relative risk of death was examined by Cox proportional hazards analyses adjusted for background (age, level of education, family situation, and county), health (longstanding illness, pain symptoms, smoking status, and psychological symptoms), and work-related factors (weekly working hours, physical and psychological demands, demands of learning at work, and perceived job insecurity). Female employees working at night had a 2.25-fold higher risk of mortality than female dayworkers (95% confidence interval [CI] 1.20-4.20) after adjustment for background and health- and work-related factors. In addition to total mortality, night work was also associated with tumor mortality. Female night workers had a 2.82-fold higher risk of tumor mortality than female dayworkers (95% CI 1.20-6.65) in the adjusted model. Among men, no such significant association was observed. The present study indicated that female night workers had a higher risk of both total and tumor mortality compared to female daytime employees. Additional research on the potential factors and mechanisms behind the association between night work and mortality is required

    The Incorporated Research Institutions for Seismology (IRIS) is funded by the National Science Foundation (NSF) to operate the facilities to generate, archive, and distribute seismological data to research communities in the United States and internationally. The IRIS Data Management System (DMS) is responsible for the ingestion, archiving, curation and distribution of these data. The IRIS Data Management Center (DMC) manages data from more than 100 permanent seismic networks, hundreds of temporary seismic deployments as well as data from other geophysical observing networks such as magnetotelluric sensors, ocean bottom sensors, superconducting gravimeters, strainmeters, surface meteorological measurements, and in-situ atmospheric pressure measurements. The IRIS DMC has data from more than 20 different types of sensors. The IRIS DMC manages approximately 100 terabytes of primary observational data. These data are archived in multiple distributed storage systems that insure data availability independent of any single catastrophic failure. Storage systems include both RAID systems of greater than 100 terabytes as well as robotic tape robots of petabyte capacity. IRIS performs routine transcription of the data to new media and storage systems to insure the long-term viability of the scientific data. IRIS adheres to the OAIS Data Preservation Model in most cases. The IRIS data model requires the availability of metadata describing the characteristics and geographic location of sensors before data can be fully archived. IRIS works with the International Federation of Digital Seismographic Networks (FDSN) in the definition and evolution of the metadata. The metadata insures that the data remain useful to both current and future generations of earth scientists. Curation of the metadata and time series is one of the most important activities at the IRIS DMC. Data analysts and an automated quality assurance system monitor the quality of the incoming data. This insures data

    We present the design and capabilities of a high-resolution, decade-spanning ASynchronous OPtical Sampling (ASOPS)-based TeraHertz Time-Domain Spectroscopy (THz-TDS) instrument. Our system employs dual mode-locked femtosecond Ti:Sapphire oscillators with repetition rates offset locked at 100 Hz via a Phase-Locked Loop (PLL) operating at the 60th harmonic of the ∼80 MHz oscillator repetition rates. The respective time delays of the individual laser pulses are scanned across a 12.5 ns window in a laboratory scan time of 10 ms, supporting a time delay resolution as fine as 15.6 fs. The repetition rate of the pump oscillator is synchronized to a Rb frequency standard via a PLL operating at the 12th harmonic of the oscillator repetition rate, achieving milliHertz (mHz) stability. We characterize the timing jitter of the system using an air-spaced etalon, an optical cross correlator, and the phase noise spectrum of the PLL. Spectroscopic applications of ASOPS-THz-TDS are demonstrated by measuring water vapor absorption lines from 0.55 to 3.35 THz and acetonitrile absorption lines from 0.13 to 1.39 THz in a short pathlength gas cell. With 70 min of data acquisition, a 50 dB signal-to-noise ratio is achieved. The achieved root-mean-square deviation is 14.6 MHz, with a mean deviation of 11.6 MHz, for the measured water line center frequencies as compared to the JPL molecular spectroscopy database. Further, with the same instrument and data acquisition hardware, we use the ability to control the repetition rate of the pump oscillator to enable THz frequency comb spectroscopy (THz-FCS). Here, a frequency comb with a tooth width of 5 MHz is generated and used to fully resolve the pure rotational spectrum of acetonitrile with Doppler-limited precision. The oscillator repetition rate stability achieved by our PLL lock circuits enables sub-MHz tooth width generation, if desired. This instrument provides unprecedented decade-spanning, tunable resolution, from 80 MHz down to sub

    Periodic microbiological monitoring of endoscopes is a recommendation of the Gastroenterological Society of Australia (GENSA). The aim of monitoring has been to provide quality assurance of the cleaning and disinfection of endoscopes; however, there is controversy regarding its frequency. This lack of consensus stimulated a review of the experience within our health service. At Southern Health, routine microbiological sampling has involved 4-weekly monitoring of bronchoscopes, duodenoscopes and automated flexible endoscope reprocessors (AFER), and 3-monthly monitoring of all other gastrointestinal endoscopes. Records of testing were reviewed from 1 January 2002 until 31 December 2006. A literature review was conducted, cost analysis performed and positive cultures investigated. There were 2374 screening tests performed during the 5-year period, including 287 AFER, 631 bronchoscopes for mycobacteria and 1456 endoscope bacterial screens. There were no positive results of the AFER or bronchoscopes for mycobacteria. Of the 1456 endoscopic bacterial samples, six were positive; however, retesting resulted in no growth. The overall cost of tests performed and cost in time for nursing staff to collect the samples was estimated at $AUD 100,400. Periodic monitoring of endoscopes is both time-consuming and costly. Our review demonstrates that AFER (Soluscope) perform well in cleaning endoscopes. Based on our 5-year experience, assurance of quality for endoscopic use could be achieved through process control as opposed to product control. Maintenance of endoscopes and AFER should be in accordance with the manufacturer's instructions and microbiological testing performed on commissioning, annually and following repair. Initial prompt manual leak testing and manual cleaning followed by mechanical leak testing, cleaning and disinfection should be the minimum standard in reprocessing of endoscopes. PMID:18086113

  19. Time scale matters: genetic analysis does not support adaptation-by-time as the mechanism for adaptive seasonal declines in kokanee reproductive life span

    Seasonal declines of fitness-related traits are often attributed to environmental effects or individual-level decisions about reproductive timing and effort, but genetic variation may also play a role. In populations of Pacific salmon (Oncorhynchus spp.), seasonal declines in reproductive life span have been attributed to adaptation-by-time, in which divergent selection for different traits occurs among reproductively isolated temporal components of a population. We evaluated this hypothesis in kokanee (freshwater obligate Oncorhynchus nerka) by testing for temporal genetic structure in neutral and circadian-linked loci. We detected no genetic differences in presumably neutral loci among kokanee with different arrival and maturation dates within a spawning season. Similarly, we detected no temporal genetic structure in OtsClock1b, Omy1009uw, or OmyFbxw11, candidate loci associated with circadian function. The genetic evidence from this study and others indicates a lack of support for adaptation-by-time as an important evolutionary mechanism underlying seasonal declines in reproductive life span and a need for greater consideration of other mechanisms such as time-dependent, adaptive adjustment of reproductive effort.

    OBJECTIVE: This single-institution experience retrospectively reviews the outcomes in a group of patients treated 5 or more years ago by pancreaticoduodenectomy for periampullary adenocarcinoma. SUMMARY BACKGROUND DATA: Controversy exists regarding the benefit of resection for periampullary adenocarcinoma, particularly for pancreatic tumors. Many series report only Kaplan-Meier actuarial 5-year survival rates. There are believed to be discrepancies between the actuarial 5-year survival data and the actual 5-year survival rates. METHODS: From April 1970 through May 1992, 242 patients underwent pancreaticoduodenal resection for periampullary adenocarcinoma at The Johns Hopkins Hospital. Follow-up was complete through May 1997. All pathology specimens were reviewed and categorized. Actual 5-year survival rates were calculated. The demographic, intraoperative, pathologic, and postoperative features of patients surviving > or =5 years were compared with those of patients who survived <5 years. RESULTS: Of the 242 patients with resected periampullary adenocarcinoma, 149 (62%) were pancreatic primaries, 46 (19%) arose in the ampulla, 30 (12%) were distal bile duct cancers, and 17 (7%) were duodenal cancers. There was a 5.3% operative mortality rate during the 22 years of the review, with a 2% operative mortality rate in the last 100 patients. There were 58 5-year survivors, 28 7-year survivors, and 7 10-year survivors. The tumor-specific 5-year actual survival rates were pancreatic 15%, ampullary 39%, distal bile duct 27%, and duodenal 59%. When compared with patients who did not survive 5 years, the 5-year survivors had a significantly higher percentage of well-differentiated tumors (14% vs. 4%; p = 0.02) and higher incidences of negative resection margins (98% vs. 73%, p < 0.0001) and negative nodal status (62% vs. 31%, p < 0.0001). The tumor-specific 10-year actuarial survival rates were pancreatic 5%, ampullary 25%, distal bile duct 21%, and duodenal 59%. CONCLUSIONS

    To succeed in academia, nursing faculty members must devote the first 5 years following the dissertation to achieving a standard to tenure characteristic of the profession. Most institutions in the country adhere to the American Association of University Professors' guidelines for tenure. These guidelines mandate excellence in teaching, scholarship, and service. A fourth characteristic, leadership, is increasingly considered in tenure decisions. The expectations of an academic career in nursing serve as the foundation for a framework to evaluate the likelihood of success in a particular setting. A detailed 5-year plan for achieving tenure is proposed. PMID:1634654

    The maintenance in the long run of a positive carbon balance under very low irradiance is a prerequisite for survival of tree seedlings below the canopy or in small gaps in a tropical rainforest. To provide a quantitative basis for this assumption, experiments were carried out to determine whether construction cost (CC) and payback time for leaves and support structures, as well as leaf life span (i) differ among species and (ii) display an irradiance-elicited plasticity. Experiments were also conducted to determine whether leaf life span correlates to CC and payback time and is close to the optimal longevity derived from an optimization model. Saplings from 13 tropical tree species were grown under three levels of irradiance. Specific-CC was computed, as well as CC scaled to leaf area at the metamer level. Photosynthesis was recorded over the leaf life span. Payback time was derived from CC and a simple photosynthesis model. Specific-CC displayed only little interspecific variability and irradiance-elicited plasticity, in contrast to CC scaled to leaf area. Leaf life span ranged from 4 months to >26 months among species, and was longest in seedlings grown under lowest irradiance. It was always much longer than payback time, even under the lowest irradiance. Leaves were shed when their photosynthesis had reached very low values, in contrast to what was predicted by an optimality model. The species ranking for the different traits was stable across irradiance treatments. The two pioneer species always displayed the smallest CC, leaf life span, and payback time. All species displayed a similar large irradiance-elicited plasticity. PMID:21511904

    We used tidal data collected in the time span 1872-2014 from a set of historical and modern stations located in the central Mediterranean, along the coasts of Italy, France, Slovenia and Croatia. The longest records span across the last two or three centuries for the tidal stations of Genova, Marseille, Trieste and Venice. While data from Bakar, Dubrovink, Rovinji and Split, all located along the coast of the Adriatic sea, provide valid records for a time span about 50 years long. In addition to these stations, since 1998 become available for the Italian region new sea level data from the dense national tidal network (www.mareografico.it). These digital stations are collecting data continuously at 10 minute sampling interval with a nominal accuracy at 1 mm. Therefore, in addition to the historical stations, we have the opportunity to analyze a sea level data set that cover about the last 16 years. In this study we show and discuss the results of our analysis of sea level data for the central Mediterranean, providing new insights on sea level trend and variability for about the past 140 years. Finally, based on sea level data and IPCC reports, we provide future sea level projections for this region for the year 2100 with implications for coastal flooding of lowland areas.

    Background Spontaneous pneumothorax (SP) is defined by the presence of air in the pleural space without history of trauma. It is classified as secondary if coexisting with underlying pulmonary disease. Its an entity with considerable incidence and treatment particularities which give reason for a reflection on the subject. We present a 5-year casuistry, characterizing the SP epidemiology, clinical presentation, investigation and therapeutic choices. Methods Sixty-six patients were included in the study, corresponding to 93 episodes of SP. Results We have found male predominance and the mean age was 34.5 years old. In 60.6% of cases there was history of tobacco use; 36.4% of cases were classified as secondary; 30.1% of patients with secondary SP and 21.7% with primary SP recurred; 89.2% had an acute presentation. The most frequent initial symptom was chest pain (90.3%) and 81.7% had diminished breath sounds. In 17.3% it was documented a physical strain associated. We did not identify statistically significant association between the SP occurrence and the variation of the atmospheric pressure, on the first day of symptoms. In 12.9% of episodes the initial treatment option was observation. In most of the episodes the lung totally expanded. However, in 29.1% of the episodes surgical treatment was needed. Conclusions Our results are similar to the literature. Some clinical records are incomplete, demanding the implementation of rules to improve knowledge about this matter.

    Routine HIV testing in primary care settings is now recommended in the United States. The US Department of Veterans Affairs (VA) has increased the number of patients tested for HIV, but overall HIV testing rates in VA remain low. A proven strategy for increasing such testing involves nurse-initiated HIV rapid testing (HIV RT). The purpose of this work was to use a mixed methodology approach to evaluate the 5-year sustainability of an intervention that implemented HIV RT in a VA emergency department setting in a large, urban VA medical center to reduce missed diagnostic and treatment opportunities in this vulnerable patient population. In-person semistructured interviews were conducted with providers and stakeholders. Interview notes were qualitatively coded for emerging themes. Quarterly testing rates were evaluated for a 5-year time span starting from the launch in July 2008. Findings indicate that HIV RT was sustained by the enthusiasm of 2 clinical champions who oversaw the registered nurses responsible for conducting the testing. The departure of the clinical champions was correlated with a substantial drop-off in testing. Findings also indicate potential strategies for improving sustainability including engaging senior leadership in the project, engaging line staff in the implementation planning from the start to increase ownership over the innovation, incorporating information into initial training explaining the importance of the innovation to quality patient care, providing ongoing training to maintain skills, and providing routine progress reports to staff to demonstrate the ongoing impact of their efforts.

However, it is uncertain especially in childhood obesity, if initial fasting hyperinsulinemia predicts obesity, or obesity leads to hyperinsulinemia through insulin resistance. Objective To investigate the predictive effect of fasting plasma insulin on subsequent weight change after a 5-year interval in childhood. Methods 424 Children from Da Qing city, China, were recruited at 5 years of age and followed up for 5 years. Blood pressure, anthropometric measurements, fasting plasma insulin, glucose and triglycerides were measured at baseline and 5 years later. Results Fasting plasma insulin at 5 years of age was significantly correlated with change of weight from 5 to 10 years (ΔWeight). Children in the lowest insulin quartile had ΔWeight of 13.08±0.73 kg compare to 18.39±0.86 in the highest insulin quartile (P<0.0001) in boys, and similarly 12.03±0.71 vs 15.80±0.60 kg (P<0.0001) in girls. Multivariate analysis showed that the predictive effect of insulin at 5 years of age on subsequent weight gain over 5 years remained statistically significant even after the adjustment for age, sex, birth weight, TV-viewing time and weight (or body mass index) at baseline. By contrast, the initial weight at 5 years of age did not predict subsequent changes in insulin level 5 years later. Children who had both higher fasting insulin and weight at 5 years of age showed much higher levels of systolic blood pressures, fasting plasma glucose, the homeostasis model assessment for insulin resistance (HOMA-IR) and triglycerides at 10 years of age. Conclusions Fasting plasma insulin at 5 years of age predicts weight gain and cardiovascular risk factors 5 year later in Chinese children of early childhood, but the absolute weight at 5 years of age did not predict subsequent change in fasting insulin.

    Two essential elements required to generate a glass transition within phase-field-crystal (PFC) models are outlined based on observed freezing behaviors in various models of this class. The central dynamic features of glass formation in simple binary liquids are qualitatively reproduced across 12 orders of magnitude in time by applying a physically motivated time scaling to previous PFC simulation results. New aspects of the equilibrium phase behavior of the same binary model system are also outlined, aging behavior is explored in the moderate and deeply supercooled regimes, and aging exponents are extracted. General features of the elastic and plastic responses of amorphous and crystalline PFC solids under deformation are also compared and contrasted.

    The objective of this study is to provide a complete quantitative assessment of the annual to decadal variability, hotspots of changes and the temporal magnitude of regional trends and variability for the main drivers of carbon cycle like climate and land use and their responses for Europe. For this purpose we used an harmonized climatic data set (ERA Interim and WATCH) and an historical land-use change reconstruction (HILDAv1, Fuchs in prep.). Both the data sets cover the period 1900-2010 and have a 0.25 deg spatial resolution. As driver response we used two different empirically up-scaled GPP fields: the first (MTE) obtained by the application of model trees (Jung et al. 2009) and a second (LUE) based on a light use efficiency model (Tomelleri in prep.). Both the approaches are based on the up-scaling of Fluxnet observations. The response fields have monthly temporal resolution and are limited to the period 1982-2011. We estimated break-points in time series of driver and response variables based on the method of Bai and Perron (2003) to identify changes in trends. This method was implemented in Verbesselt et al. 2010 and applied by deJong et al. 2011 to detect phenological and abrupt changes and trends in vegetation activity based on satellite-derived vegetation index time series. The analysis of drivers and responses allowed to identify the dominant factors driving the biosphere-atmosphere carbon exchange. The synchronous analysis of climatic drivers and land use change allowed us to explain most of the temporal and spatial variability showing that in the regions and time period where the most land use change occurred the climatic drivers are not sufficient to explain trends and oscillation in carbon cycling. The comparison of our analysis for the up-scaling methods shows some agreement: we found inconsistency in the spatial and temporal patterns in regions where the Fluxnet network is less dense. This can be explained by the conceptual difference in the up

    Pre-packed small scale chromatography columns are increasingly used for process development, for determination of design space in bioprocess development, and for post-licence process verifications. The packing quality of 30,000 pre-packed columns delivered to customers over a period 10 years has been analyzed by advanced statistical tools. First, the data were extracted and checked for inconsistencies, and then were tabulated and made ready for statistical processing using the programming language Perl (https://www.perl.org/) and the statistical computing environment R (https://www.r-project.org/). Reduced HETP and asymmetry were plotted over time to obtain a trend of packing quality over 10 years. The obtained data were used as a visualized coefficient of variation analysis (VCVA), a process that has often been applied in other industries such as semiconductor manufacturing. A typical fluctuation of reduced HETP was seen. A Tsunami effect in manufacturing, the effect of propagation of manufacturing deviations leading to out-of-specification products, was not observed with these pre-packed columns. Principal component analysis (PCA) showed that all packing materials cluster. Our data analysis showed that the current commercially available chromatography media used for biopharmaceutical manufacturing can be reproducibly and uniformly packed in polymer-based chromatography columns, which are designed for ready-to-use purposes. Although the number of packed columns has quadrupled over one decade the packing quality has remained stable. PMID:27575920

    Robust chronological framework is a crucial necessity for palaeoclimate reconstructions and especially for synchronizing records to decipher climatic teleconnections. Volcanic ash deposits (tephra) provide isochronous time marker that can be utilized as tie-lines to synchronize sedimentary archives. Advances in the detection and identification of non-visible (crypto-) tephra, often transported over thousands of kilometers, also allows identifying ash deposits even in distal records. We report the first findings of co-existing early Holocene Hässeldalen and Askja-S cryptotephras in a varved sediment record in Lake Czechowskie (JC, northern Poland). Annual layer counting was used to establish a varve chronology and micro-facies analyses, relative calcium (Ca) and titanium (Ti) concentrations were used to decipher between lake productivity and detrital flux. Here we focus (i) on the determination of the time span between both tephras, (ii) revised age estimates for the Askja-S tephra and (iii) the sedimentological response of the JC record to the Preboreal Oscillation (PBO), a short lived cold episode during the early Holocene. A differential dating approach revealed a time span of 152 +11/-8 varve years counted in the JC sediment record between both tephras. Since the varved interval of the JC sediment record comprising the tephras is floating, we anchored the floating varve chronology to an absolute timescale by using the radiocarbon-dated Hässeldalen Tephra (11,380 ± 216 cal a BP, Wohlfarth et al, 2006). The resulting age for the Askja-S of 11,454-11,002 cal a BP is, even considering the rather large uncertainties, a few decades to several hundred years older than most radiocarbon based age models, but it supports the original age model from Hässseldala port. The sediment response to the PBO cold period is seen only in a slight decrease in titanium, a proxy for detrital matter flux. Varve micro-facies did not change during this interval confirming a weak impact

    We focus on natural disturbances of the sub-ionospheric VLF waveguide in the time span 2009 to 2015 (sunspot cycle 24), i.e. variations in amplitude and phase measurements of the radio paths are considered. In particular we're investigating numerous solar flares (up to X-class), geomagnetic storms and substorms, therefore discuss how to discriminate natural from artificial variations between different transmitters and receivers. Meteorological effects could be important [1] and we estimate the possibility to detect the influence of lithospheric sources in the VLF radio links. As part of the VLF multistation network we're using the single receiver mid-latitude station in Graz, Austria. This facility receives up to 12 transmitter simultaneously (frequency range 10-50 kHz), has 20 sec temporal resolution, and is running continuously since 2009 [2]. We obtain the statistics relating VLF amplitude and phase fluctuations with C/M/X-class solar flares, and characterise night time fluctuations in connection with enhanced particle precipitation in the northern latitude path (Iceland transmitter). The statistics is important to improve the quality of seismo-electromagnetic studies. We conclude that for ionospheric perturbations (D-layer), e.g. solar flares, a reliable real time monitoring service can be established. Atmospheric and lithospheric variations are generally difficult to characterise, it's harder to distinguish between natural and man made signals, therefore - as a future outlook - complementary ground and satellite based measurements can deliver valuable additional information for environmental monitoring.

    Survival time prediction at the time of diagnosis is of great importance to make decisions about treatment and long-term follow-up care. However, predicting the outcome of cancer on the basis of clinical information is a challenging task. We now examined the ability of ten different data mining algorithms (Perceptron, Rule Induction, Support Vector Machine, Linear Regression, Naïve Bayes, Decision Tree, k-nearest Neighbor, Logistic Regression, Neural Network, Random Forest) to predict the dichotomous attribute "5-year-survival" based on seven attributes (sex, UICC-stage, etc.) which are available at the time of diagnosis. For this study we made use of the nationwide German research data set on colon cancer provided by the Robert Koch Institute. To assess the results a comparison between data mining algorithms and physicians' opinions was performed. Therefore, physicians guessed the survival time by leveraging the same seven attributes. The average accuracy of the physicians' opinion was 59%, the average accuracy of the machine learning algorithms was 67.7%. PMID:26152957

    acquiring new genes from other strains via a process called reassortment. However, little is known about the relationship between mutation accumulation and gene reassortment for rotaviruses and how it impacts viral evolution. In this study, we analyzed the genome sequences of human strains found in clinical fecal specimens that were collected at a single hospital over an 18-year time span. We found that many rotaviruses did not reassort their genes but instead maintained them as specific sets (i.e., constellations). By analyzing the encoded proteins, we discovered concurrent amino acid changes among them, which suggests that they are functionally coadapted to operate best when kept together. This study increases our understanding of how rotaviruses evolve over time in the human population. PMID:24942570

    Time spans of soil formation and climate changes occurred during the late Pleistocene to the middle Holocene are investigated in a pedostratigraphic succession located in the piedmont of the Somma-Vesuvius volcano (Campania region, southern Italy) using a multidisciplinary approach. We focused on five well-known and well-dated primary tephra and four interlayered volcanic soils developed on and/or buried by them. The pyroclastic layers give detailed chronological constraints to the stratigraphy. From bottom to top the following tephra were identified in the field: Pomici di Base (22 ka BP), Pomici Verdoline (19 ka BP), Agnano Pomici Principali (12.26 ka BP), Mercato (8.9 ka BP) and Avellino (3.9 ka BP), all of them representing volcanic products of explosive eruptions of the Somma-Vesuvius, except the third one, sourced from the westerly Phlegrean Fields. The four pedons were characterized in terms of morphological, physical, chemical, mineralogical and micromorphological features. Special attention was given to reconstruct the main soil-forming processes, paleoenvironmental and paleoclimatic conditions, degree of soil development and associated time ranges. Moreover, further tephra were identified in the field within some of above pedons. One of them was easily recognized and referred to the Agnano Monte Spina eruption (4.2-4.3 ka BP, Phlegrean Fields provenance), whereas the others were not previously known in the Somma-Vesuvius stratigraphy. On the basis of SEM-EDS analyses (chemical composition and morphoscopic observations), coupled with their stratigraphic position and literature compositional databases, they were related to the Soccavo 4-5 and the Tufi Biancastri eruptions from the Phlegrean Fields. This interpretation permitted to fix further age constrains for more detailed assessment of rates of soil formation and climatic interpretation. Major late Quaternary climatic phases are suggested by changes in the extent of development of andic properties, iron

    We explored the relation between the causes of facial injuries in equestrians and the presence or absence of associated injuries. Over a 5-year period we retrospectively reviewed all patients who presented to the John Hunter Hospital, New South Wales, with facial injuries that had resulted from activity with horses. We analysed the rates of hard and soft tissue injuries, and of associated injuries by sex and mechanism. A total of 85 patients were included (50 female and 35 male) with an age range of 2-88 years. There was a significant difference in the rate of maxillofacial and associated injuries when groups were analysed for sex and mechanism of injury. Facial injuries caused by falling from a horse were more often associated with other injuries in men than in women (p<0.05), and men were 4 times more likely to present with associated injuries than women (OR 3.9; 95% CI 1.1 to 14) We also found significant differences in the rates of facial fracture. Women who had been kicked by a horse were more likely to sustain bony injuries than men (p<0.05). Our data confirm the association between kicks and facial fracture, and this may provide an impetus for the development of appropriate protective equipment. Patients who sustain facial injuries when falling from a horse often present with associated injuries and this has practical implications for clinicians involved in their management. PMID:24168759

    Lucena, Thomas R; Lam, Patrick H; Millar, Neal L

    2015-01-01

    Background The present study aimed to determine how repair technique influenced structural and clinical outcomes at 5 years post-surgery. Methods Three cohorts of patients had repair of a symptomatic rotator cuff tear using (i) an open double-row mattress repair technique (n = 25); (ii) arthroscopic single-row simple suture knotted technique (n = 25); or (iii) arthroscopic single-row inverted mattress knotless technique (n = 36) by one surgeon. Standardized patient- and examiner-determined outcomes were obtained pre-operatively and postoperatively with a validated protocol, ultrasound were also performed at the same time. Results Retear occurred more often after open repair (48%) at 5 years than after arthroscopic knotted (33%) and arthroscopic knotless (26%) repair. Retear was associated with increasing age, pre-operative tear size and weaker pre-operative and 5 years postoperative cuff strength. Between 2 years and 5 years, the open repair group experienced an increase in the frequency of pain during activity, as well as in the difficulty experienced and the severity of pain during overhead activities (p < 0.05) and, at 5 years, also experienced more difficulty with overhead activities, compared to the arthroscopic knotless repair group. Conclusions At 5-year follow-up, arthroscopic rotator cuff repair techniques resulted in fewer retears and better outcomes compared to an open double-row technique.

    Problem Programs that encourage scholarly activities beyond the core curriculum and traditional biomedical research are now commonplace among US medical schools. Few studies have generated outcome data for these programs. The goal of the present study was to address this gap. Intervention The Scholarly Concentration (SC) Program, established in 2006 at the Warren Alpert Medical School of Brown University, is a 4-year elective program that not only encourages students to pursue scholarly work that may include traditional biomedical research but also seeks to broaden students’ focus to include less traditional areas. We compared characteristics and academic performance of SC students and non-SC students for the graduating classes of 2010–2014. Context Approximately one-third of our students opt to complete an SC during their 4-year undergraduate medical education. Because this program is additional to the regular MD curriculum, we sought to investigate whether SC students sustained the academic achievement of non-SC students while at the same time producing scholarly work as part of the program. Outcome Over 5 years, 35% of students elected to enter the program and approximately 81% of these students completed the program. The parameters that were similar for both SC and non-SC students were age at matriculation, admission route, proportion of undergraduate science majors, and number of undergraduate science courses. Most academic indicators, including United States Medical Licensing Examinations scores, were similar for the two groups; however, SC students achieved more honors in the six core clerkships and were more likely to be inducted into the medical school's two honor societies. Residency specialties selected by graduates in the two groups were similar. SC students published an average of 1.3 peer-reviewed manuscripts per student, higher than the 0.8 manuscripts per non-SC student (p=0.013). Conclusions An elective, interdisciplinary scholarly program with

    Although considered pristine, Antarctica has not been impervious to hydrocarbon pollution. Antarctica's history is peppered with oil spills and numerous abandoned waste disposal sites. Both spill events and constant leakages contribute to previous and current sources of pollution into marine sediments. Here we compare the response of the benthic diatom communities over 5 years to exposure to a commonly used standard synthetic lubricant oil, an alternative lubricant marketed as more biodegradable, in comparison to a control treatment. Community composition varied significantly over time and between treatments with some high variability within contaminated treatments suggesting community stress. Both lubricants showed evidence of significant effects on community composition after 5 years even though total petroleum hydrocarbon reduction reached approximately 80% over this time period. It appears that even after 5 years toxicity remains high for both the standard and biodegradable lubricants revealing the temporal scale at which pollutants persist in Antarctica. PMID:25499184

    Purpose To review the 5-year outcomes of our modified mandibulotomy technique. Retrospective review of a tertiary level oral cancer center. Materials and Methods During a 5-year period, 30 patients who had a uniform surgical technique consisting of a lower lip-splitting, modified stair-step osteotomy with thin saw blade and osteotome after plate-precontouring and combination fixation with monocortical osteosynthesis (miniplate) and bicortical osteosynthesis (maxiplate and bicortical screws), with at least 14 months postoperative follow-up, were selected and reviewed retrospectively. Results There were 8 women and 22 men with an average age of 56.5 years. All the patients involved malignancies were squamous cell carcinoma. The main primary sites of the those who underwent a mandibulotomy were the tonsil, the base of tongue, the oral tongue, the retromolar pad area, and others. Others included buccal cheek, floor of mouth, and soft palate. 23 patients received postoperative radiation therapy, and among whom 8 patients also received chemotherapy. Total four (13%) mandibulotomy-related complications occurred, only two (6.7%) requiring additional operation under general anesthesia. Conclusion Our modified mandibulotomy meets the criteria for an ideal mandibulotomy technique relatively well because it requires no intermaxillary fixation, can precise preserve the occlusion in a precise way, allows early function, requires no secondary procedures, and has few complications.

    Purpose: To report the 5-year results of a technique of prone breast radiation therapy delivered by a regimen of accelerated intensity modulated radiation therapy with a concurrent boost to the tumor bed. Methods and Materials: Between 2003 and 2006, 404 patients with stage I-II breast cancer were prospectively enrolled into 2 consecutive protocols, institutional trials 03-30 and 05-181, that used the same regimen of 40.5 Gy/15 fractions delivered to the index breast over 3 weeks, with a concomitant daily boost to the tumor bed of 0.5 Gy (total dose 48 Gy). All patients were treated after segmental mastectomy and had negative margins and nodal assessment. Patients were set up prone: only if lung or heart volumes were in the field was a supine setup attempted and chosen if found to better spare these organs. Results: Ninety-two percent of patients were treated prone, 8% supine. Seventy-two percent had stage I, 28% stage II invasive breast cancer. In-field lung volume ranged from 0 to 228.27 cm{sup 3}, mean 19.65 cm{sup 3}. In-field heart volume for left breast cancer patients ranged from 0 to 21.24 cm{sup 3}, mean 1.59 cm{sup 3}. There was no heart in the field for right breast cancer patients. At a median follow-up of 5 years, the 5-year cumulative incidence of isolated ipsilateral breast tumor recurrence was 0.82% (95% confidence interval [CI] 0.65%-1.04%). The 5-year cumulative incidence of regional recurrence was 0.53% (95% CI 0.41%-0.69%), and the 5-year overall cumulative death rate was 1.28% (95% CI 0.48%-3.38%). Eighty-two percent (95% CI 77%-85%) of patients judged their final cosmetic result as excellent/good. Conclusions: Prone accelerated intensity modulated radiation therapy with a concomitant boost results in excellent local control and optimal sparing of heart and lung, with good cosmesis. Radiation Therapy Oncology Group protocol 1005, a phase 3, multi-institutional, randomized trial is ongoing and is evaluating the equivalence of a similar dose and

    PURPOSE The aim of this retrospective study was to evaluate cumulative survival rate (CSR) of Implantium implants followed for 5 years and association between risk factors and the CSR. MATERIALS AND METHODS A total of two hundred forty-nine Implantium Implants System (Dentium, Seoul, Korea) placed in ninety-five patients from 2004 to 2009 were investigated with several identified risk factors (sex, systemic disease, smoking, alchohol, reason of tooth loss, length, arch (maxilla or mandible), replace tooth type (incisor, canine, premolar or molar) Kennedy classification, prosthodontic type, prosthodontic design, opposite dentition, abutment type, occlusal material, occlusal unit, splint to tooth, cantilever, other surgery). Clinical examination (mobility, percussion, screw loosening, discomfort, etc.) and radiographic examination data were collected from patient records including all problems during follow-up period according to protocols described earlier. Life table analysis was undertaken to examine the CSR. Cox regression method was conducted to assess the association between potential risk factors and overall CSR. RESULTS Five of 249 implants were failed. Four of these were lost before loading. The 5-year implant cumulative survival rate was 97.37%. Cox regression analysis demonstrated a significant predictive association between overall CSR and systemic disease, smoking, reason of tooth loss, arch, Kennedy classification and prosthodontic design (P<.05). The screw related complication was rare. Two abutment screw fractures were found. Another complications of prosthetic components were porcelain fracture, resin facing fracture and denture fracture (n=19). CONCLUSION The 5-year CSR of Implantium implants was 97.37%. Implant survival may be dependent upon systemic disease, smoking reason of tooth loss, arch, Kennedy classification and prosthodontic design (P<.05). The presence of systemic diseases and combination of other surgical procedures may be associated

    The vast majority of circumcisions currently performed in the UK are for phimosis or balanitis and the patients are not looking for the denuded glans appearance of a ritual circumcision. We present a refinement of the sleeve technique of circumcision, which involves Horton's test to define the proximal incision margin, and bipolar electro-dissection. A review of all patients undergoing circumcision at the Wordsley Plastic Surgery Unit, in a 5-year period, has shown this technique to be safe with a haematoma rate of only 1.4%, and an overall complication rate of 3%.

    The Duraloc cup is a frequently used metal-backed, porous-coated, hemispherical, press-fit acetabular component. Published data on loosening rates are contradictory. In this study we investigated migration patterns with computer-assisted Einzel-Bild-Roentgen-Analyse (EBRA) of 67 Duraloc 100 cups. Cup migration and clinical scores were analysed over a 5-year follow-up period. Median total migration of the Duraloc 100 cup was 1.21 mm at 5 years. Seventy-five percent of implants were radiologically stable at 2 years and 90% at 4 years. One cup loosened aseptically at 60 months, requiring revision. Cup diameters > or = 54 mm migrated significantly more than cups < 54 mm in diameter (p = 0.029 at 4 years). There was a significant correlation between high polyethylene wear and further migrating cups within the first post-operative year (p = 0.035 at 12 months). Our analysis revealed significantly higher wear in males (p = 0.029 at 4 years). Radiological loosening at two years could be calculated using receiver-operating characteristic curve analysis, and 1.2 mm as an adequate threshold value (sensitivity = 100%, specificity = 89%).

    The objective of this study was to create a 5-year survivorship model to identify key clinical features of cystic fibrosis. Such a model could help researchers and clinicians to evaluate therapies, improve the design of prospective studies, monitor practice patterns, counsel individual patients, and determine the best candidates for lung transplantation. The authors used information from the Cystic Fibrosis Foundation Patient Registry (CFFPR), which has collected longitudinal data on approximately 90% of cystic fibrosis patients diagnosed in the United States since 1986. They developed multivariate logistic regression models by using data on 5,820 patients randomly selected from 11,630 in the CFFPR in 1993. Models were tested for goodness of fit and were validated for the remaining 5,810 patients for 1993. The validated 5-year survivorship model included age, forced expiratory volume in 1 second as a percentage of predicted normal, gender, weight-for-age z score, pancreatic sufficiency, diabetes mellitus, Staphylococcus aureus infection, Burkerholderia cepacia infection, and annual number of acute pulmonary exacerbations. The model provides insights into the complex nature of cystic fibrosis and supplies a rigorous tool for clinical practice and research. PMID:11207152

    Bulimia nervosa shows a marked tendency to persist, suggesting that powerful maintaining mechanisms operate. Using data from a prospective, 5-year, study of the natural course of 102 people with bulimia nervosa, the authors sought to identify predictors of persistence and to test specific hypotheses derived from the cognitive-behavioral theory of the persistence of bulimia nervosa. The results of both sets of analyses were consistent with the theory, with the degree of overevaluation of shape and weight and a history of childhood obesity predicting a persistent course. There was also support for the central prediction of the cognitive-behavioral theory. These findings suggest that the mechanisms specified by the theory influence its longer term natural course.

    2000-07-01

    We present a case of pyomyositis in an otherwise healthy 5-year-old child that underscores the potential for serious, life-threatening complications. Pyomyositis of the gluteal, psoas, and iliacus muscles was associated with osteomyelitis, septic arthritis, a large inferior vena cava thrombus, septic pulmonary emboli, and eventual pneumonia. Primary pyomyositis is a purulent infection of striated muscle thought to be caused by seeding from a transient bacteremia. The focal infection typically forms an abscess that generally responds to intravenous antibiotics and occasionally requires adjunctive computed tomography-guided aspiration and drainage. This localized infectious process rarely produces further sequelae unless treatment is delayed. Pyomyositis is rare in healthy individuals and requires a high clinical suspicion in patients who present with fever, leukocytosis, and localized pain. PMID:10910315

    Purpose Our aim was to evaluate an optical coherence tomography (OCT) and visual acuity (VA)-guided, variable-dosing regimen with intravitreal ranibizumab injection for treating patients with neovascular age-related macular degeneration (AMD) from 2007 to 2012. Design This was a retrospective clinical study of 5 years follow-up in a tertiary eye center. Patients and methods In this study, 66 patients with neovascular AMD (mean age of 74 years, SD 8.7 years) were included. We investigated the development of best-corrected visual acuity (BCVA), the number of intravitreal injections, and the central retinal thickness measured with OCT (OCT Spectralis) over 5 years of intravitreal treatment. Results The mean number of intravitreal ranibizumab injections over 5 years was 8.8. The mean BCVA before therapy was 0.4 logarithm of the minimum angle of resolution (logMAR). After 5 years of therapy, the mean BCVA was 0.6 logMAR. In all, 16% of treated patients had stable VA over 5 years and 10% of study eyes approved their VA. The mean OCT-measured central retinal thickness at the beginning of this study was 295 µm; after 5 years of treatment, the mean central retinal thickness was 315 µm. There was an increase in central retinal thickness in 47.5% of examined eyes. Conclusion Other studies showed VA improvement in OCT-guided variable-dosing regimens. Our study revealed a moderate decrease in VA after a total mean injection number as low as 8.8 injections over 5 years. In OCT, an increase in central retinal thickness over 5 years could be observed. Probably, this is due to deficient treatment when comparing the total injection number to other treatment regimens. Anti-VEGF therapy helps to keep the VA stable for a period of time, but cannot totally stop the progression of the disease completely. Patients with late stages of neovascular AMD can maintain VA even if they are relatively undertreated. PMID:27354758

    By conducting a case-control study in two university hospitals, we explored the association between modifiable risk behaviours and diarrhoea. Children aged <5 years attending outpatient clinics for diarrhoea were matched by age and sex with controls. Data were collected on family demographics, socioeconomic indicators, and risk behaviour practices. Two rectal swabs and a stool specimen were collected from cases and controls. Samples were cultured for bacterial pathogens using standard techniques and tested by ELISA to detect rotavirus and Cryptosporidium spp. Four hundred cases and controls were enrolled between 2007 and 2009. The strongest independent risk factors for diarrhoea were: presence of another household member with diarrhoea [matched odds ratio (mOR) 4.9, 95% CI 2.8-8.4] in the week preceding the survey, introduction to a new kind of food (mOR 3, 95% CI 1.7-5.4), and the child being cared for outside home (mOR 2.6, 95% CI 1.3-5.2). While these risk factors are not identifiable, in some age groups more easily modifiable risk factors were identified including: having no soap for handwashing (mOR 6.3, 95% CI 1.2-33.9) for children aged 7-12 months, and pacifier use (mOR 1.9, 95% CI 1.0-3.5) in children aged 0-6 months. In total, the findings of this study suggest that community-based interventions to improve practices related to sanitation and hygiene, handwashing and food could be utilized to reduce the burden of diarrhoea in Egyptian children aged <5 years.

    Although the causative agent of bovine viral diarrhea was initially categorized as 1 species, phylogenetic analysis revealed that these viruses belong to 2 different species, Bovine viral diarrhea virus 1 (BVDV-1) and BVDV-2, with 2-11 subgenotypes within each species. Distribution of species and subgenotypes has been shown to vary with geographic region. Whether distribution shifts over time is not known. Surveys conducted between 1994 and 2008 reported 3 subgenotypes circulating among cattle in the United States: BVDV-1a, BVDV-1b, and BVDV-2a. The average percent prevalence of BVDV-1a, BVDV-1b, and BVDV-2a strains reported in surveys before 2001 were 21%, 43%, and 36%, respectively. Surveys conducted on viruses isolated after 2001 reported decreasing percentages of BVDV-1a and BVDV-2a strains, with BVDV-1b strains accounting for 75-100% of samples. Comparison of these surveys is confounded by differences in geographic location, collection methods, and sample type used in the survey. The purpose of the present study was to determine whether the prevalence of BVDV subgenotypes shifted in samples collected from the same geographic region and by the same laboratory over time. BVDV strains isolated in years 1988, 1998, and 2008, at the Texas Veterinary Medical Diagnostic Laboratory, Amarillo, Texas, were genotyped, and the prevalence of BVDV-1a, BVDV-1b, and BVDV-2a strains were determined. Typing, on the basis of phylogenetic analysis, was done on 148 samples. The strongest trend detected among these samples was a pronounced decrease in the number of BVDV-1a strains over time.

    Objective A long-term effect of hereditary hemochromatosis (HH) on aerobic exercise capacity (AEC) has not been well described. Design Forty-three HH and 21 volunteer control (VC) subjects who were asymptomatic underwent cardiopulmonary exercise testing using the Bruce protocol. AEC was assessed with minute ventilation (VE), oxygen uptake (VO2), and carbon dioxide production (VCO2) at baseline (BL) at a 5-year follow up (5Y) assessment. A paired t-test was used for analyses of normality data; otherwise, a Wilcoxon singed rank sum test was used. Results Thirty-three HH subjects and 18 VC subjects returned for a repeat CPX at 5Y (80% overall return rate). At 5Y, AEC was not different between the two groups. As compared with BL measurements, exercise time, peak VO2, and the VE/VCO2 slope did not differ statistically at 5Y between both groups. Iron depletion by phlebotomy for 5 years did not significantly affect AEC in newly diagnosed HH subjects at baseline (n=14) and cardiac arrhythmias during exercise tended to decrease after 5 years of therapy in this group. Conclusions The AEC of asymptomatic HH subjects treated with conventional therapy is not statistically affected by the disease over a 5-year period. PMID:22311055

    Background Current literature examining associations between vitamin D and chronic disease generally use a single assessment of 25-hydroxyvitamin D (25(OH)D), assuming an individual’s 25(OH)D concentration is consistent over time. Methods We investigated the intraindividual variability between two measures of plasma 25(OH)D concentrations collected ~5 years apart (1997-2000 to 2002-2005) in 672 postmenopausal women participating in the Women’s Health Initiative. Plasma 25(OH)D was assessed using the DiaSorin LIAISON® chemiluminescence immunoassay. The within-pair coefficient of variation (CV) was 4.9% using blinded quality control samples. Mean and standard deviations (SD) of 25(OH)D at the two time points were compared using a paired t-test. An intraindividual CV and intra-class correlation coefficient (ICC) were used to assess intraindividual variability. A Spearman correlation coefficient (r) assessed the strength of the association between the two measures and concordance in vitamin D status at two time points Results Mean 25(OH)D concentrations (nmol/L) significantly increased over time from 60.0 (SD=22.2) to 67.8 (SD=22.2) (p<0.05). The CV was 24.6%, the ICC (95% Confidence Interval (CI)) was 0.59 (0.54-0.64), and the Spearman r was 0.61 (95% CI=0.56-0.66). Greater concordance over 5 years was observed in participants with sufficient compared to deficient or inadequate baseline 25(OH)D concentrations (weighted kappa=0.39). Reliability measures were moderately influenced by season of blood draw and vitamin D supplement use. Conclusion There is moderate intraindividual variation in 25(OH)D concentrations over approximately 5 years. Impact These data support the use of a one-time measure of blood 25(OH)D in prospective studies with ≤ 5 years of follow-up. PMID:22523182

    The vertical segments of Populus stems are an ideal experimental system for analyzing the gene expression patterns involved in primary and secondary growth during wood formation. Suitable internal control genes are indispensable to quantitative real time PCR (qRT-PCR) assays of gene expression. In this study, the expression stability of eight candidate reference genes was evaluated in a series of vertical stem segments of Populus tomentosa. Analysis through software packages geNorm, NormFinder and BestKeeper showed that genes ribosomal protein (RP) and tubulin beta (TUBB) were the most unstable across the developmental stages of P. tomentosa stems, and the combination of the three reference genes, eukaryotic translation initiation factor 5A (eIF5A), Actin (ACT6) and elongation factor 1-beta (EF1-beta) can provide accurate and reliable normalization of qRT–PCR analysis for target gene expression in stem segments undergoing primary and secondary growth in P. tomentosa. These results provide crucial information for transcriptional analysis in the P. tomentosa stem, which may help to improve the quality of gene expression data in these vertical stem segments, which constitute an excellent plant system for the study of wood formation.

    Taking advantage of wide-field, time-lapse microscopy we examined the assembly of vascular polygonal networks in whole bird embryos and in explanted embryonic mouse tissue (allantois). Primary vasculogenesis assembly steps range from cellular (1-10 μm) to tissue (100μm-1mm) level events: Individual vascular endothelial cells extend protrusions and move with respect to the extracellular matrix/surrounding tissue. Consequently, long-range, tissue-level, deformations directly influence the vascular pattern. Experimental perturbation of endothelial-specific cell-cell adhesions (VE-cadherin), during mouse vasculogenesis, permitted dissection of the cellular motion required for sprout formation. In particular, cells are shown to move actively onto vascular cords that are subject to strain via tissue deformations. Based on the empirical data we propose a simple model of preferential migration along stretched cells. Numerical simulations reveal that the model evolves into a quasi-stationary pattern containing linear segments, which interconnect above a critical volume fraction. In the quasi-stationary state the generation of new branches offsets the coarsening driven by surface tension. In agreement with empirical data, the characteristic size of the resulting polygonal pattern is density-independent within a wide range of volume fractions. These data underscore the potential of combining physical studies with experimental embryology as a means of studying complex morphogenetic systems. In collaboration with Brenda J.

    The NASA Infrared Telescope Facility (IRTF) is a 3-meter optical/IR telescope dedicated to NASA-related programs of mission support and basic solar system research. All of the funding for IRTF operations comes from the Planetary Astronomy Program. We are preparing the Cooperative Agreement with NASA for the next 5 years (Feb. 2006 -- Jan. 2011). We will strive to refurbish the telescope in order to provide mission support and to allow the IRTF to provide fundamental data for future missions to Mars, comets, satellites, Near-Earth Objects, and asteroids. A major component of our activities will be to improve the image quality of the telescope and to provide high dynamic imaging on the IRTF. Details of our plans can be obtained at: http://irtfweb.ifa.hawaii.edu/Documents/pdf/1_plan_mar04C.pdf We acknowledge the support of NASA Cooperative Agreement no.

    Blunt traumatic cardiac rupture is associated with a high rate of mortality. A review of the computerized trauma registry (1983 to 1988) identified 32 patients with this injury (ages 19 to 65 years; mean age, 39.5 years; 21 men and 11 women). Twenty-one patients (65.6%) were injured in vehicular crashes, 3 (9.4%) in pedestrian accidents, 3 (9.4%) in motorcycle accidents; 3 (9.4%) sustained crush injury; 1 (3.1%) was injured by a fall; and 1 (3.1%) was kicked in the chest by a horse. Anatomic injuries included right atrial rupture (13[40.6%]), left atrial rupture (8 [25%]), right ventricular rupture (10[31.3%]), left ventricular rupture (4[12.5%]), and rupture of two cardiac chambers (3 [9.4%]). Diagnosis was made by thoracotomy in all 20 patients presenting in cardiac arrest. In the remaining 12 patients, the diagnosis was established in seven by emergency left anterolateral thoracotomy and in five by subxyphoid pericardial window. Seven of these 12 patients (58.3%) had clinical cardiac tamponade and significant upper torso cyanosis. The mean Injury Severity Score (ISS), Trauma Score (TS), and Glasgow Coma Scale (GCS) score were 33.8, 13.2, and 14.3, respectively, among survivors and 51.5, 8.3, and 7.0 for nonsurvivors. The overall mortality rate was 81.3% (26 of 32 patients), the only survivors being those presenting with vital signs (6 of 12 patients [50%]). All patients with rupture of two cardiac chambers or with ventricular rupture died. The mortality rate from myocardial rupture is very high. Rapid prehospital transportation, a high index of suspicion, and prompt surgical intervention contribute to survival in these patients. PMID:2256761

    In 2006, the SciDAC Scientific Data Management (SDM) Center proposed to continue its work deploying leading edge data management and analysis capabilities to scientific applications. One of three thrust areas within the proposed center was focused on Scientific Process Automation (SPA) using workflow technology. As a founding member of the Kepler consortium [LAB+09], the SDM Center team was well positioned to begin deploying workflows immediately. We were also keenly aware of some of the deficiencies in Kepler when applied to high performance computing workflows, which allowed us to focus our research and development efforts on critical new capabilities which were ultimately integrated into the Kepler open source distribution, benefiting the entire community. Significant work was required to ensure Kepler was capable of supporting large-scale production runs for SciDAC applications. Our work on generic actors and templates have improved the portability of workflows across machines and provided a higher level of abstraction for workflow developers. Fault tolerance and provenance tracking were obvious areas for improvement within Kepler given the longevity and complexity of our target workflows. To monitor workflow execution, we developed and deployed a web-based dashboard. We then generalized this interface and released it so it could be deployed at other locations. Outreach has always been a primary focus of our work and we had many successful deployments across a number of scientific domains while continually publishing and presenting our work. This short paper describes our most significant accomplishments over the past 5 years. Additional information about the SDM Center can be found in the companion paper: The Scientific Data Management Center: Available Technologies and Highlights.

    The Space Physics Analysis Network (SPAN) is a computer network connecting scientific institutions throughout the United States. This network provides an avenue for timely, correlative research between investigators, in a multidisciplinary approach to space physics studies. An objective in the development of SPAN is to make available direct and simplified procedures that scientists can use, without specialized training, to exchange information over the network. Information exchanges include raw and processes data, analysis programs, correspondence, documents, and graphite images. This handbook details procedures that can be used to exchange graphic images over SPAN. The intent is to periodically update this handbook to reflect the constantly changing facilities available on SPAN. The utilities described within reflect an earnest attempt to provide useful descriptions of working utilities that can be used to transfer graphic images across the network. Whether graphic images are representative of satellite servations or theoretical modeling and whether graphics images are of device dependent or independent type, the SPAN graphics display utilities handbook will be the users guide to graphic image exchange.

    Fleischer, Rudolf; Xu, Xiaoming

    We study the minimum diameter color-spanning set problem which has recently drawn some attention in the database community. We show that the problem can be solved in polynomial time for L 1 and L ∞ metrics, while it is NP-hard for all other L p metrics even in two dimensions. However, we can efficiently compute a constant factor approximation.

    Objective: The aim of this study was to determine the percentage of 5-year-old preschoolers in Sharjah, affected by dental erosion and to assess the predictors. Materials and Methods: A total of 403 5-year-old children were examined of which 48.14% (n = 194) were boys and 51.86% (n = 209) were girls; 31.27% (n = 126) were Emirati and 68.73% (n = 277) were non-Emirati Arabs. Examination of dental erosion was confined to palatal surfaces of maxillary incisors using the erosion index described in the UK National Survey of Children's Dental Health, 1993. Dental caries was charted using the World Health Organization 1997 criteria. Results: In the sample of 403 5-year-old preschoolers examined, dental erosion was apparent in 237 (58.80%) children, with 55.09% showing the dissolution of enamel and 3.72% exhibiting exposed dentin. Predictors of dental erosion as determined by logistic regression concluded that compared to Emirati citizens other Arab nationalities have 0.27 times the odds (95% confidence interval [CI] =0.18–0.42) of having tooth erosion (P < 0.05). Children with caries experience have 0.28 times the odds (95% CI = 0.16–0.51) of having tooth erosion compared to children with no caries experience (P < 0.05). Children who drink sugary or carbonated beverages have 0.30 times the odds (95% CI = 0.19–0.41) of having dental erosion compared to children who drink water (P < 0.05). Conclusions: The findings of this study indicate that 58.80% of 5-year-old preschoolers in Sharjah, United Arab Emirates, were affected by dental erosion. Caries experience and consumption of acidic drinks were associated with dental erosion. PMID:27095899

    2010-01-01

    In the absence of long-term field studies, demographic and reproductive records from animals housed in zoos and research laboratories are a valuable tool for the study of life history variables relating to reproduction. In this study, we analyzed studbook records of more than 2,000 individuals born over a 40-year period (1965-2004) to describe life history patterns of captive Goeldi's monkeys (Callimico goeldii) housed in North America and Europe. Using Kaplan-Meier survival analysis methods, we found the mean life span to be 5.5 years. The rate of infant mortality, defined as death before 30 days, was approximately 30%, with European animals being more likely to survive infancy than North American animals. When individuals surviving at least 1.5 years are considered, lifetime reproductive output averaged 3.5 offspring, yet more than one-third of individuals did not produce any offspring. Using a smaller dataset of individuals with known pairing histories, we developed a measure of opportunity for reproduction (OFR), which represented the total time an individual was known to be housed with a potential mate. For both sexes, we found that the correlation between OFR and number of offspring produced was much higher than the correlation between life span and number of offspring produced. This result highlights the importance of taking into account an individual's OFR. As a whole, our findings help characterize the life histories of captive Goeldi's monkeys and emphasize the impact management practices may have on reproductive success. PMID:20131357

    Meeting the medical and social needs of elderly people is likely to be costly, disruptive, and at odds with personal preferences if efforts to do so are not well coordinated. We compared two different models of primary care in four different continuing care retirement communities. In the first model, used in one community, the physicians and two part-time nurse practitioners delivered clinical care only at that site, covered all settings within it, and provided all after-hours coverage. In the second model, used in three communities, on-site primary care physician hours were limited; the same physicians also had independent practices outside the retirement community; and after-hours calls were covered by all members of the practices, including physicians who did not practice on site. We found that residents in the first model had two to three times fewer hospitalizations and emergency department visits. Only 5 percent of those who died did so in a hospital, compared to 15 percent at the other sites and 27 percent nationally. These findings provide insight into what is possible when medical care is highly integrated into a residential retirement setting. PMID:21555482

    In this cross-sectional study, the authors examined the relationship between emotion and behavior regulation in 3- and 5-year olds. Eighty-seven children performed a compliance sorting task. The authors manipulated the demand for emotion regulation by presenting and then hiding toys (low) or making toys visible (high). Mothers and teachers rated children's coping responses. Five-year-olds sorted less in the high condition than in the low condition, and 3-year-olds spent equal time sorting in both conditions. Compliance was positively correlated with problem-focused coping and negatively correlated with emotion-focused coping. Correlations between emotion and behavior regulation were stronger for the 5-year-olds. Age groups were differently affected by the higher demands of emotion regulation, indicating that the child's resources for regulation interact with the task demands to determine behavioral outcome.

    Background: Pulmonary nocardiosis is a rare but a life-threatening infection caused by Nocardia spp. The diagnosis is often missed and delayed resulting in delay in appropriate treatment and thus higher mortality. Aim: In this study, we aim to evaluate the clinical spectrum and outcome of patients with pulmonary nocardiosis. Methods: A retrospective, 5-year (2009–2014) review of demographic profile, risk factors, clinical manifestations, imaging findings, treatment, and outcome of patients with pulmonary nocardiosis admitted to a tertiary care hospital. Results: The median age of the study subjects was 54 years (range, 16–76) and majority of them (75%) were males. The risk factors for pulmonary nocardiosis identified in our study were long-term steroid use (55.6%), chronic lung disease (52.8%), diabetes (27.8%), and solid-organ transplantation (22.2%). All the patients were symptomatic, and the most common symptoms were cough (91.7%), fever (78%), and expectoration (72%). Almost two-third of the patients were initially misdiagnosed and the alternative diagnosis included pulmonary tuberculosis (n = 7), community-acquired pneumonia (n = 5), lung abscess (n = 4), invasive fungal infection (n = 3), lung cancer (n = 2), and Wegener's granulomatosis (n = 2). The most common radiographic features were consolidation (77.8%) and nodules (56%). The mortality rate for indoor patients was 33% despite treatment. Higher mortality rate was observed among those who had brain abscess (100.0%), HIV positivity (100%), need for mechanical ventilation (87.5%), solid-organ transplantation (50%), and elderly (age > 60 years) patients (43%). Conclusion: The diagnosis of pulmonary nocardiosis is often missed and delayed resulting in delay in appropriate treatment and thus high mortality. A lower threshold for diagnosing pulmonary nocardiosis needs to be exercised, in chest symptomatic patients with underlying chronic lung diseases or systemic immunosuppression, for the early diagnosis

    AYUSH is an acronym for Ayurveda, Yoga and Naturopathy, Unani, Siddha, and Homeopathy. These are the six indigenous systems of medicine practiced in India. A department called Department of Indian System of medicine was created in March 1995 and renamed to AYUSH in November 2003 with a focus to provide increased attention for the development of these systems. Very recently, in 2014, a separate ministry was created under the union Government of India, which is headed by a minister of state. Planning regarding these systems of medicine was a part of 5-year planning process since 1951. Since then many developments have happened in this sector albeit the system was struggling with a great degree of uncertainty at the time of 1st5-year plan. A progressive path of development could be observed since the first to the 12th5-year plan. It was up to the 7thplan the growth was little sluggish and from 8thplan onward the growth took its pace and several innovative development processes could be observed thereafter. The system is gradually progressing ahead with a vision to be a globally accepted system, as envisaged in 11th5-year plan. Currently, AYUSH system is a part of mainstream health system implemented under National Rural Health Mission (NRHM). NRHM came into play in 2005 but implemented at ground level in 2006 and introduced the scheme of “Mainstreaming of AYUSH and revitalization of local health traditions” to strengthen public health services. This scheme is currently in operation in its second phase, since 1stApril 2012, with the 12th5-year plan. The scheme was primarily brought in to operation with three important objectives; choice of treatment system to the patients, strengthen facility functionally and strengthen the implementation of national health programmes, however, in some places it seems to be a forced medical pluralism owing to a top-down approach by the union government without considerable involvement of the concerned community.

    IMPORTANCE Discontinuation of bisphosphonate therapy after 3 to 5 years is increasingly considered, but methods to monitor fracture risk after discontinuation have not been established. OBJECTIVE To test methods of predicting fracture risk among women who have discontinued alendronate therapy after 4 to 5 years. DESIGN, SETTING, AND PARTICIPANTS The prospective Fracture Intervention Trial Long-term Extension (FLEX) study randomized postmenopausal women aged 61 to 86 years previously treated with 4 to 5 years of alendronate therapy to 5 more years of alendronate or placebo from 1998 through 2003; the present analysis includes only the placebo group. Hip and spine dual-energy x-ray absorptiometry (DXA) were measured when placebo was begun (FLEX baseline) and after 1 to 3 years of follow-up. Two biochemical markers of bone turnover, urinary type 1 collagen cross-linked N-telopeptide (NTX) and serum bone-specific alkaline phosphatase (BAP), were measured at FLEX baseline and after 1 and 3 years. MAIN OUTCOMES AND MEASURES Symptomatic spine and nonspine fractures occurring after the follow-up measurement of DXA or bone turnover. RESULTS During 5 years of placebo, 94 of 437 women (22%) experienced 1 or more symptomatic fractures; 82 had fractures after 1 year. One-year changes in hip DXA, NTX, and BAP were not related to subsequent fracture risk, but older age and lower hip DXA at time of discontinuation were significantly related to increased fracture risk (lowest tertile of baseline femoral neck DXA vs other 2 tertiles relative hazard ratio, 2.17 [95%CI, 1.38–3.41]; total hip DXA relative hazard ratio, 1.87 [95%CI, 1.20–2.92]). CONCLUSIONS AND RELEVANCE Among postmenopausal women who discontinue alendronate therapy after 4 to 5 years, age and hip BMD at discontinuation predict clinical fractures during the subsequent 5 years. Follow-up measurements of DXA 1 year after discontinuation and of BAP or NTX 1 to 2 years after discontinuation are not associated with

    The aim of the study was to develop a newly devised child observation sheet (COS-5) as a scoring sheet, based on the Childhood Autism Rating Scale (CARS), for use in the developmental evaluation of 5-year-old children, especially focusing on children with autistic features, and to verify its validity. Seventy-six children were studied. The children were recruited among participants of the Japan Children's Cohort Study, a research program implemented by the Research Institute of Science and Technology for Society (RISTEX) from 2004 to 2009. The developmental evaluation procedure was performed by doctors, clinical psychologists, and public health nurses. The COS-5 was also partly based on the Kyoto Scale of Psychological Development 2001 (Kyoto Scale 2001). Further, the Developmental Disorders Screening Questionnaire for 5-Years-Olds, PDD-Autism Society Japan Rating Scale (PARS), doctor interview questions and neurological examination for 5-year-old children, and the Draw-a-Man Test (DAM) were used as evaluation scales. Eighteen (25.4%) children were rated as Suspected, including Suspected PDD, Suspected ADHD and Suspected MR. The COS-5 was suggested to be valid with favorable reliability (α=0.89) and correlation with other evaluation scales. The COS-5 may be useful, with the following advantages: it can be performed within a shorter time frame; it facilitates the maintenance of observation quality; it facilitates sharing information with other professions; and it is reliable to identify the autistic features of 5-year-old children. In order to verify its wider applications including the screening of infants (18months to 3years old) by adjusting the items of younger age, additional study is needed. PMID:23415454

    The goal of this cross-sectional study was to compare cognitive functioning at age 5 years in prenatal drug-exposed children with nondrug-exposed children from a comparable inner-city environment. Children with prenatal drug exposure scored significantly lower on measures of language, school readiness skills, impulse control, and visual attention span/sequencing than controls matched for age and socioeconomic status. Intelligence, visual-motor, manual dexterity, and sustained attention scores were not significantly different between groups. The total sample scored significantly below the normative mean on standardized measures of intelligence, language, school readiness, visual-motor skills, impulse control, and sustained attention, with 40% scoring at least 1 standard deviation below the mean (IQ <85) on a measure of intelligence. Findings suggest that children with prenatal drug exposure are at increased risk for learning and attention problems and are in need of close developmental surveillance and possible intervention to support school success and improve behavioral outcome.

    Ingested foreign bodies are common in the cohort of psychiatric patients, however clinical quiescence in this group is rare. We present a case of a 45-year-old female with emotionally unstable personality disorder (borderline type) presenting with partial intestinal obstruction 5 years after the known ingestion of serrated metallic scissors. In the asymptomatic interim a conservative approach of tracking the blades radiologically was taken. Following discussion, we conclude the following: early surgical intervention is encouraged if natural passage does not occur within 3 days following ingestion, and that any concurrent surgical needs should be addressed at this time.

    Employing some 40 years of North Pacific drifter-track observations from the Global Drifter Program database, statistics defining the horizontal spread of radionuclides from Fukushima nuclear power plant into the Pacific Ocean are investigated over a time scale of 5 years. A novel two-iteration method is employed to make the best use of the available drifter data. Drifter-based predictions of the temporal progression of the leading edge of the radionuclide distribution are compared to observed radionuclide concentrations from research surveys occupied in 2012 and 2013. Good agreement between the drifter-based predictions and the observations is found.

    Practice guidelines endorse maintenance antidepressant treatment for recurrent major depressive disorder. In the Vantaa Depression Study, we followed 218 psychiatric patients with major depressive disorder for up to 5 years with a life-chart. Of these patients, 86 (39.4%) had more than three lifetime episodes and an indication for maintenance pharmacotherapy. However, of these, only 57% received treatment and only for 16% of the time indicated. Good adherence to pharmacotherapy in the acute phase independently predicted maintenance treatment. The tertiary preventive impact of maintenance treatment may remain limited, as many patients with major depressive disorder either do not receive it, or receive it for too short a period.

    Ingested foreign bodies are common in the cohort of psychiatric patients, however clinical quiescence in this group is rare. We present a case of a 45-year-old female with emotionally unstable personality disorder (borderline type) presenting with partial intestinal obstruction 5 years after the known ingestion of serrated metallic scissors. In the asymptomatic interim a conservative approach of tracking the blades radiologically was taken. Following discussion, we conclude the following: early surgical intervention is encouraged if natural passage does not occur within 3 days following ingestion, and that any concurrent surgical needs should be addressed at this time.

    Employing some 40 years of North Pacific drifter-track observations from the Global Drifter Program database, statistics defining the horizontal spread of radionuclides from Fukushima nuclear power plant into the Pacific Ocean are investigated over a time-scale of 5 years. A novel two-iteration method is employed to make the best use of the available drifter data. Drifter-based predictions of the temporal progression of the leading edge of the radionuclide distribution are compared to observed radionuclide concentrations from research surveys occupied in 2012 and 2013. Excellent agreement between the drifter-based predictions and the observations is found.

    Background Few studies have characterized longer-term outcomes after retropubic and transobturator midurethral slings. Methods Women completing 2-year participation in a randomized equivalence trial who had not received surgical retreatment for stress urinary incontinence were invited to participate in a 5-year observational cohort. The primary outcome, treatment success, was defined as no retreatment or self-reported stress incontinence symptoms. Secondary outcomes included urinary symptoms and quality of life, satisfaction, sexual function and adverse events. Results 404 of 597 (68%) women from the original trial enrolled. Five-years after surgical treatment, success was 7.9% greater in women assigned to retropubic-sling compared to transobturator-sling (51.3% vs 43.4%, 95% CI −1.4%, 17.2%) not meeting pre-specified criteria for equivalence. Satisfaction decreased over 5-years, but remained high and similar between arms (79%, retropubic-sling vs 85%, transobturator-sling groups, p=0.15). Urinary symptoms and quality of life worsened over time (p<0.001), and women with retropubic-sling reported greater urinary urgency (P=0.001), more negative quality of life impact (p=0.02), and worse sexual function (P=0.001). There was no difference in proportion of women experiencing at least 1 adverse event (p=0.17). Seven new mesh erosions were noted (retropubic-sling-3, transobturator-sling-4). Conclusion Treatment success declined over 5-years for retropubic and transobturator-slings and did not meet pre-specified criteria for equivalence with retropubic demonstrating a slight benefit. However, satisfaction remained high in both arms. Women undergoing transobturator-sling reported more sustained improvement in urinary symptoms and sexual function. New mesh erosions occurred in both arms over time, although at a similarly low rate. PMID:25158274

    In this study, we compared outcomes of traditional apicoectomy versus modern apicoectomy, by means of a controlled clinical trial with a 5-year follow-up. The study investigated 938 teeth in 843 patients. On the basis of the procedure performed, the teeth were grouped in 3 groups. Differences between the groups were the method of osteotomy (type of instruments used), type of preparation of retrograde cavity (different apicoectomy angles and instruments used for root-end preparation), and root-end filling material used (gray mineral trioxide aggregate or silver amalgam). Outcome (tooth healing) was estimated after 1 and 5 years, postoperatively. Clinical success rates after 1 year were 67% (306 teeth), 90% (186 teeth), and 94% (256 teeth) according to traditional apicoectomy (group 1), modern microsurgical apicoectomy using burns for osteotomy (group 2) or using piezo-osteotomy (group 3), respectively. After 1 year, group comparison results were statistically significant (P < 0.0001). Linear trend test was also statistically significant (P < 0.0001), pointing out larger healing from group 1 to group 3. After 5 years, teeth were classified into 2 groups on the basis of root-end filling material used. Clinical success was 90.8% (197 teeth) in the silver amalgam group versus 96% (309 teeth) in the mineral trioxide aggregate group (P < 0.00214). Multiple logistic regression analysis found that surgical technique was independently associated to tooth healing. In conclusion, modern apicoectomy resulted in a probability of success more than 5 times higher (odds ratio, 5.20 [95% confidence interval, 3.94-6.92]; P < 0.001) compared with the traditional technique.

    The pharmacodynamic (PD) action of tacrolimus (FK) within the T-cell is inhibition of calcineurin phosphatase (CaN). Determination of CaN activity provides us with an important PD marker. Eleven renal transplant patients treated with FK were investigated on day 14 following transplantation and 5 years later. Blood samples drawn before as well as 1, 2, 3, and 4 hours after oral intake of FK were analyzed for CaN activity and blood FK concentrations. Twenty healthy subjects had one blood sample drawn for CaN activity, which was measured as the release of (32)P from a phosphorylated peptide. Radioactivity of (32)P was quantitated by liquid scintillation counting with the results converted to units of CaN utilizing a calibration curve. On day 14, we observed significant inhibition of CaN activity at T:1, 2, and 3 compared with the predose level (P = .002; P = .015; P = .015). Furthermore, all measured CaN activities were significantly different from those observed in healthy nonmedicated subjects. In contrast, at 5 years posttransplant only the CaN activity at T:2 was significantly inhibited compared with the predose level (P = .02). Additionally, all CaN activities at this time were not significantly different from CaN activities in the healthy subjects. We were not able to demonstrate individual CaN activity profiles in the patients. The lack of CaN inhibition at 5 years after transplantation despite relevant drug concentrations, probably reflected the lower drug dose used long after transplantation. This result raises the question of whether CaN inhibition is necessary to hold graft function and whether FK possess CaN-independent mechanisms of action. PMID:17098028

    Fetal body composition is an important determinant of body composition at birth, and it is likely to be an important determinant at later stages in life. The purpose of this work is to provide a comprehensive overview by presenting data from previously published studies that report on body composition during fetal development in newborns and the infant/child through 5 years of age. Understanding the changes in body composition that occur both in utero and during infancy and childhood, and how they may be related, may help inform evidence-based practice during pregnancy and childhood. We describe body composition measurement techniques from the in utero period to 5 years of age, and identify gaps in knowledge to direct future research efforts. Available literature on chemical and cadaver analyses of fetal studies during gestation is presented to show the timing and accretion rates of adipose and lean tissues. Quantitative and qualitative aspects of fetal lean and fat mass accretion could be especially useful in the clinical setting for diagnostic purposes. The practicality of different pediatric body composition measurement methods in the clinical setting is discussed by presenting the assumptions and limitations associated with each method that may assist the clinician in characterizing the health and nutritional status of the fetus, infant and child. It is our hope that this review will help guide future research efforts directed at increasing the understanding of how body composition in early development may be associated with chronic diseases in later life.

    The Advanced Land Imager (ALI) was developed as a prototype sensor for follow on missions to Landsat-7. It was launched in November 2000 on the Earth Observing One (EO-1) satellite as a nominal one-year technology demonstration mission. As of this writing, the sensor has continued to operate in excess of 5 years. Six of the ALl's nine multi-spectral (MS) bands and the panchromatic band have similar spectral coverage as those on the Landsat-7 ETM+. In addition to on-board lamps, which have been significantly more stable than the lamps on ETM+, the ALI has a solar diffuser and has imaged the moon monthly since launch. This combined calibration dataset allows understanding of the radiometric stability of the ALI system, its calibrators and some differentiation of the sources of the changes with time. The solar dataset is limited as the mechanism controlling the aperture to the solar diffuser failed approximately 18 months after launch. Results over 5 years indicate that: the shortest wavelength band (443 nm) has degraded in response about 2%; the 482 nm and 565 nm bands decreased in response about 1%; the 660 nm, 790 nm and 868 nm bands each degraded about 5%; the 1250 nm and 1650 nm bands did not change significantly and the 2215 nm band increased in response about 2%.

    We present the results of a 5-year patient follow-up after implantation of an original neuroprosthesis. The system is able to stimulate both epimysial and neural electrodes in such a way that the complete flexor-extensor chain of the lower limb can be activated without using the withdrawal reflex. We demonstrate that standing and assisted walking are possible, and the results have remained stable for 5 years. Nevertheless, some problems were noted, particularly regarding the muscle response on the epimysial channels. Analysis of the electrical behaviour and thresholds indicated that the surgical phase is crucial because of the sensitivity of the functional responses to electrode placement. Neural stimulation proved to be more efficient and more stable over time. This mode requires less energy and provides more selective stimulation. This FES system can be improved to enable balanced standing and less fatiguing gait, but this will require feedback on event detection to trigger transitions between stimulation sequences, as well as feedback to the patient about the state of his lower limbs.

    OBJECTIVE: This longitudinal investigation examines whether fathers' prenatal involvement (e.g., attending doctor appointments and discussing pregnancy with mother) and residence status at infant's birth predict the first time a father becomes inaccessible to his child (defined as seeing child fewer than a few times per month) at six developmental time points in children's first 5 years. DESIGN: Data were gathered from 2,160 ethnically diverse mothers (i.e., European American, African American, and Latin American) who participated in the National Early Head Start Research and Evaluation Project. Survival analysis was used to predict the timing of father inaccessibility based on interviews. RESULTS: By prekindergarten, fathers' residence at birth and prenatal involvement decreased their risk of being inaccessible to their children for the first time by 71% and 47%, respectively, after adjusting for all other variables in the model. Residence at birth was a stronger predictor of the timing of father inaccessibility than was prenatal involvement for European American and Latin American fathers; for African American fathers, prenatal involvement was a stronger predictor of the timing of father inaccessibility than nonresidential status at birth. Nearly 65% of fathers who were engaged in both prenatal activities remained consistently accessible to their child through child age of 63 months, whereas nearly 50% of fathers who were not prenatally involved were already inaccessible by the time infants were 3 months. CONCLUSION: These findings have implications for early intervention programs aimed at strengthening the role of fathers in their families from the prenatal period. PMID:20333276

    A visual stimulus at a particular location of the visual field may elicit a behavior while at the same time equally salient stimuli in other parts do not. This property of visual systems is known as selective visual attention (SVA). The animal is said to have a focus of attention (FoA) which it has shifted to a particular location. Visual attention normally involves an attention span at the location to which the FoA has been shifted. Here the attention span is measured in Drosophila. The fly is tethered and hence has its eyes fixed in space. It can shift its FoA internally. This shift is revealed using two simultaneous test stimuli with characteristic responses at their particular locations. In tethered flight a wild type fly keeps its FoA at a certain location for up to 4s. Flies with a mutation in the radish gene, that has been suggested to be involved in attention-like mechanisms, display a reduced attention span of only 1s. PMID:26848852

    Zhou, Jian; Chen, Lu; Wang, Ke; Yang, Fan

    2016-04-01

    In this paper, the minimum spanning tree problem is investigated on the graph with fuzzy edge weights. The notion of fuzzy ? -minimum spanning tree is presented based on the credibility measure, and then the solutions of the fuzzy ? -minimum spanning tree problem are discussed under different assumptions. First, we respectively, assume that all the edge weights are triangular fuzzy numbers and trapezoidal fuzzy numbers and prove that the fuzzy ? -minimum spanning tree problem can be transformed to a classical problem on a crisp graph in these two cases, which can be solved by classical algorithms such as the Kruskal algorithm and the Prim algorithm in polynomial time. Subsequently, as for the case that the edge weights are general fuzzy numbers, a fuzzy simulation-based genetic algorithm using Prüfer number representation is designed for solving the fuzzy ? -minimum spanning tree problem. Some numerical examples are also provided for illustrating the effectiveness of the proposed solutions.

    2016-06-01

    The perceptual span is a standard measure of parafoveal processing, which is considered highly important for efficient reading. Is the perceptual span a stable indicator of reading performance? What drives its development? Do initially slower and faster readers converge or diverge over development? Here we present the first longitudinal data on the development of the perceptual span in elementary school children. Using the moving window technique, eye movements of 127 German children in three age groups (Grades 1, 2, and 3 in Year 1) were recorded at two time points (T1 and T2) 1year apart. Introducing a new measure of the perceptual span, nonlinear mixed-effects modeling was used to separate window size effects from asymptotic reading performance. Cross-sectional differences were well replicated longitudinally. Asymptotic reading rate increased monotonously with grade, but in a decelerating fashion. A significant change in the perceptual span was observed only between Grades 2 and 3. Together with results from a cross-lagged panel model, this suggests that the perceptual span increases as a consequence of relatively well-established word reading. Stabilities of observed and predicted reading rates were high after Grade 1, whereas the perceptual span was only moderately stable for all grades. Comparing faster and slower readers as assessed at T1, in general, a pattern of stable between-group differences emerged rather than a compensatory pattern; second and third graders even showed a Matthew effect in reading rate and the perceptual span, respectively.

    In the widely used Corsi Block Test and Wechsler Spatial Span Tests, participants must reproduce sequences of blocks in the order touched by the examiner until two trials are missed at the same sequence length. The examiner records either the maximum number of blocks correctly reported or the total number of correct lists. Here, we describe a computerized spatial span test (C-SST) that uses psychophysical procedures to quantify visuospatial mean span (MnS) with sub-digit precision. Results from 187 participants ranging in age from 18 to 82 years showed that accuracy declined gradually with list length around the MnS (by ∼30% per item). Simulation studies revealed high variance and biases in CBT and Wechsler measures, and demonstrated that the C-SST provided the most accurate estimate of true span (i.e., the sequence length producing 50% correct). MnS declined more rapidly with age than mean digit span (MnDS) measured in the same participants. Response times correlated with both MnS and MnDS scores. Error analysis showed that omission and transposition errors predominated, with weaker primacy and recency effects in spatial span than digit span testing. The C-SST improves the precision of spatial span testing and reveals significant differences between visuospatial and verbal working memory. PMID:26357906

    Objective To report the 5-year risk and to identify risk factors for the development of a seminal acute or progressive clinical event in a multi-national cohort of asymptomatic subjects meeting 2009 RIS Criteria. Methods Retrospectively identified RIS subjects from 22 databases within 5 countries were evaluated. Time to the first clinical event related to demyelination (acute or 12-month progression of neurological deficits) was compared across different groups by univariate and multivariate analyses utilizing a Cox regression model. Results Data were available in 451 RIS subjects (F: 354 (78.5%)). The mean age at from the time of the first brain MRI revealing anomalies suggestive of MS was 37.2 years (y) (median: 37.1 y, range: 11–74 y) with mean clinical follow-up time of 4.4 y (median: 2.8 y, range: 0.01–21.1 y). Clinical events were identified in 34% (standard error = 3%) of individuals within a 5-year period from the first brain MRI study. Of those who developed symptoms, 9.6% fulfilled criteria for primary progressive MS. In the multivariate model, age [hazard ratio (HR): 0.98 (95% CI: 0.96–0.99); p = 0.03], sex (male) [HR: 1.93 (1.24–2.99); p = 0.004], and lesions within the cervical or thoracic spinal cord [HR: 3.08 (2.06–4.62); p = <0.001] were identified as significant predictors for the development of a first clinical event. Interpretation These data provide supportive evidence that a meaningful number of RIS subjects evolve to a first clinical symptom. An age <37 y, male sex, and spinal cord involvement appear to be the most important independent predictors of symptom onset. PMID:24598783

    Strokes are common neurological disorders in Thailand. Rehabilitation programs significantly improve arm function outcomes if performed during the sub-acute period of stroke rehabilitation, within 6 months of the attack. This report describes the case of a stroke patient who gained upper extremity motor recovery after 5 years, which is beyond the normal recovery period. Although the patient does not have functionality, she has partial motor recovery, and she is enthusiastic about learning to gain better use of her hand. However there is still limited evidence to use in designing effective intervention and proper timing of rehabilitation administered by personnel in training chronic stroke patients. Therefore, evidence based on neuroplasticity and neurological recovery in chronic stroke patients, including rehabilitation intervention, is presented in this report. PMID:27266238

    Many patients present to the emergency department complaining of a sore or stiff neck and lateral flexion of the neck with contralateral rotation. Under the pressure of the breaching time and busy shifts some of the patients are discharged to the care of their general practitioners without adequate investigations. While most of the cases are due to benign causes, torticollis can be due to many congenital and acquired pathologies, some of which may need further investigation and urgent management. Atlantoaxial subluxation (AAS), tumours of the base of the skull and infections are among these causes. Delayed diagnosis may lead to worsening neurology and complicate the management. We report a case of a 5-year-old girl who presented to our fracture clinic with a fractured clavicle and torticollis; her subsequent investigations confirmed the diagnosis of AAS. Our patient responded to non-operative treatment and improved with no neurological complications. PMID:24832710

    I have performed total knee arthroplasty (TKA) using patient- specific instrumentation (PSI) (TRUMATCH® Personalized Solutions, DePuy Synthes Joint Reconstruction, Warsaw, Indiana) since July 2009. Since that time, I have performed over 600 of these procedures, all at the same hospital and all using the same personnel I worked with before I began using PSI. I do not have a physician assistant, but I do have a surgical assistant who scrubs with and assists me on all TKAs. There are a number of reasons why a surgeon may decide to use PSI. This paper discusses the effect PSI has had on my practice in the last 5 years, including my experiences and conclusions. PMID:24911641

    Purpose: To audit referral practices of pediatric oncologists referred to specialist pediatric palliative care services. Patients and Methods: Retrospective review of medical case records of pediatric palliative care patients over a period of 5 years from January 1, 2010 to December 31, 2014. Descriptive summaries of demographic, clinical variables, and patient circumstances at the time of referral and during end-of-life care were examined. Results: A total of 1135 patients were referred from pediatric oncology with a gradual increasing trend over 5 years. About 84.6% consultations took place in the outpatient setting. In 97.9% of the cases, parents were the primary caregivers. Availability of specialist pediatric health-care services at local places was available in 21.2% cases and 48% families earned <5000 INR (approximately 73 USD) in a month. Around 28.3% of the referrals were from leukemia clinic and maximum references were late with 72.4% patients having advanced disease at presentation. 30.3% of the referrals were made for counseling and communication and 54.2% had high symptom burden during referral. After referral, 21.2% patients continued with oral metronomic chemotherapy and 10.5% were referred back to oncology services for palliative radiotherapy. Only 4.9% patients had more than 2 follow-ups. 90.8% of the patients were cared for at home in the last days of illness by local general practitioners. 70.6% of the deaths were anticipated. Conclusions: Oncologists referred patients late in the course of disease trajectory. Most of the referrals were made for counseling and communication, but many patients had high symptom burden during referral. PMID:27559254

Conclusion These findings have implications for early intervention programs aimed at strengthening the role of fathers in their families from the prenatal period. PMID:20333276

    Interactions between the sexes influence evolution at many scales, but not all animal species conform to the familiar male-female (dioecious) mating system; such taxa are powerful tools for studying the evolutionary importance of sexual selection and conflict on all manner of life-history traits, including longevity. We tested for an effect of mating system on adult life span in Pristionchus nematodes, where self-fertile hermaphrodites have replaced females multiple times independently throughout the genus (androdioecy). By measuring adult life span for 11 species (6 dioecious, 5 androdioecious), we found that life span is considerably shorter in hermaphrodites relative to closely related females. This effect is not a cost of reproduction; brood size did not reliably trade off with life span in self-fertilizing hermaphrodites or in mated females. Furthermore, we found that sexual dimorphism in life span varied among dioecious species, with females generally outliving males. Finally, we documented intraspecific variation for life span and cuticular disease (blistering) prevalence in Pristionchus pacificus, a model system for evolutionary-developmental biology. This work demonstrates that mating system transitions and life span evolution are linked in Pristionchus nematodes and provides a foundation for future comparative and mechanistic studies of aging in this genus.

    Background Cardiac tumors are rare but manifested with various clinical presentations and often cause unexpected symptoms or sudden death. The objective is to review the clinical presentation, histopathological spectrum, mortality and follow-up data of patients with cardiac tumors following surgery treatment over a period of 5 years. Methods We retrospectively collected the medical records of all patients diagnosed of cardiac tumors in the period between January 2008 and December 2013 at the cardiac center of our university. Clinical histories, perioperative data, surgical findings, efficacy and follow-up data were reviewed in our study. Patients were divided into two groups according to site distribution of the tumors in the heart. Results A total of 131 patients underwent surgical treatment of cardiac tumors were enrolled in this study, with a mean age of 51.39±16.37. The result of analysis showed that 79.47% (n=104) of the primary intracardiac tumors were benign, while primary malignant neoplasms accounted for 16.03% (n=21) of all patients, with the remainder (n=6, 4.6%) metastatic tumors transferred from other organs. Among all patients there were 2 in-hospital deaths and the survival rate in all patients at 1-year, 3-year and 5-year follow up was 83.20%, 78.62% and 66.41% respectively. Both patients with tumors in the left and right heart had similar basic characteristics except sex gender (P=0.002), BSA (P=0.045) and weight (P=0.033). Compared with patients with tumors in the right heart, patients with tumors in the left heart had significant higher CPB time (P<0.001), cross clamp time (P<0.001) and time of mechanical ventilation (P<0.001), and they also had longer ICU stay (P<0.001) but not total hospital stay (P=0.434). Conclusions Surgical resection represents an effective protocol in treating cardiac tumors. Data in our study of cardiac tumors on frequency and allocation were consistent with previous reports which may provide useful clinical evidence on

  7. How The Genome Got a Life Span

    2015-01-01

    In the space of little more than a decade, ideas of the human genome have shifted significantly, with the emergence of the notion that the genome an individual changes with development, age, disease, environmental inputs, and time. This paper examines the emergence of the genome with a life span, one that experiences drift, instability and mutability, and a host of other temporal changes. We argue that developments in chromatin biology have provided the basis for this genomic embodiment of experience and exposure. We analyze how time has come to matter for the genome through chromatin, providing analysis of examples in which the human life course is being explored as a set of material changes to chromatin. A genome with a lifespan aligns the molecular and the experiential in new ways, shifting ideas of life stages, their interrelation, and the temporality of health and disease. PMID:26213491

    In this paper, using a moving window to scan through every stock price time series over a period from 2 January 2001 to 11 March 2011 and mutual information to measure the statistical interdependence between stock prices, we construct a corresponding weighted network for 501 Shanghai stocks in every given window. Next, we extract its maximal spanning tree and understand the structure variation of Shanghai stock market by analyzing the average path length, the influence of the center node and the p-value for every maximal spanning tree. A further analysis of the structure properties of maximal spanning trees over different periods of Shanghai stock market is carried out. All the obtained results indicate that the periods around 8 August 2005, 17 October 2007 and 25 December 2008 are turning points of Shanghai stock market, at turning points, the topology structure of the maximal spanning tree changes obviously: the degree of separation between nodes increases; the structure becomes looser; the influence of the center node gets smaller, and the degree distribution of the maximal spanning tree is no longer a power-law distribution. Lastly, we give an analysis of the variations of the single-step and multi-step survival ratios for all maximal spanning trees and find that two stocks are closely bonded and hard to be broken in a short term, on the contrary, no pair of stocks remains closely bonded for a long time.

  9. Extended attention span training system

    Attention Deficit Disorder (ADD) is a behavioral disorder characterized by the inability to sustain attention long enough to perform activities such as schoolwork or organized play. Treatments for this disorder include medication and brainwave biofeedback training. Brainwave biofeedback training systems feed back information to the trainee showing him how well he is producing the brainwave pattern that indicates attention. The Extended Attention Span Training (EAST) system takes the concept a step further by making a video game more difficult as the player's brainwaves indicate that attention is waning. The trainee can succeed at the game only by maintaining an adequate level of attention. The EAST system is a modification of a biocybernetic system that is currently being used to assess the extent to which automated flight management systems maintain pilot engagement. This biocybernetic system is a product of a program aimed at developing methods to evaluate automated flight deck designs for compatibility with human capabilities. The EAST technology can make a contribution in the fields of medical neuropsychology and neurology, where the emphasis is on cautious, conservative treatment of youngsters with attention disorders.

    Four metallic materials of economic significance were exposed to an urban atmosphere up to five years. These materials were low carbon steel, zinc (as galvanized steel), copper and aluminum all of commercial quality. The corrosion rate was measured after 1, 2, 3 and 5 years using a weight loss method. Sulfur dioxide deposition rate and climatological parameters were determined monthly. At the same time, different techniques were used to characterize the corrosion products developed on the above materials. Results obtained by polarization resistance technique (Rp) in a 0.1 M Na{sub 2}SO{sub 4} solution revealed that, the longer the exposure time, the greater the corrosion products protection, as result of broadening and compactness of such products, this was verified by scanning electron microscopy (SEM). Through x-rays diffraction (XRD), the expected crystalline compounds on steel and copper were identified and also, the transformation of middling protective initial products into other more protective was followed. For aluminum and zinc it was not possible to identify the crystalline compounds perhaps due to the very thin corrosion products layers. So, these materials were analyzed by means of Raman spectroscopy. a-Al{sub 2}O, was identified on an aluminum sample whereas on zinc any corrosion product could not be identified due to excessive fluorescence.

  11. Facebook as a medium for promoting statement of intent for organ donation: 5-years of experience.

    Brzeziński, Michał; Klikowicz, Paweł

    2015-01-01

    The number of potential registered organ donors does not cover the actual demand in most developed countries. Therefore, methods increasing awareness and interest in organ donation, including modern tools of social marketing, are being researched worldwide. The aim of this paper is to present our 5-year experiences with a Facebook networking campaign - the Dawca.pl Club. The mission of the campaign is to raise awareness and educate Polish society on tissue, cell, and organ transplants, to increase public acceptance for transplants as a treatment method, and to increase the number of voluntary donors signing consents for organ donation. The project is based on the idea of creating a community promoting transplantation, focused around the Dawca.pl Club. At present the club has over 48,000 registered members - people who declared willingness to donate their organs after death. We present a description of members of this social networking service, the possibilities of using it to promote transplants and organ donation, and the efficacy of selected schemes for creating and publishing content on Facebook. The example of Dawca.pl shows that 2-way relations, spread over time, are required for social media to effectively engage and exert influence in a chosen sphere of public health and medicine. Unfortunately, at this time it is difficult to assess how such campaigns, apart from raising social awareness and acceptance, will affect the number of transplantations of organs from living and deceased donors.

    2015-01-01

    Objective The purpose was to study associations between tooth brushing frequency, use of fluoride lozenges and consumption of sugary drinks at 1.5 year of age and having caries experience at 5 years of age. Methods This study was based on data from the Norwegian Mother and Child Cohort Study conducted by the Norwegian Institute of Public Health and by the Public Dental Services. A total of 1095 children were followed from pregnancy to the age of 5 years. Questionnaires regarding oral health behavior were completed by the parents at 1.5 and 5 years of age. Clinical and radiographic examination of the children was performed at the age of 5 years. Results In multiple logistic regression, having caries experience at 5 years of age was associated with; at 1.5 year of age having the teeth brushed less than twice daily (OR 2.1, CI 1.3–3.6) and being offered sugary drinks at least once a week (OR 1.8, CI 1.1–2.9) when controlled for family characteristics and oral health behavior at 5 years of age. Conclusions Tooth brushing frequency and consumption of sugary drinks in early childhood were related to caries development during preschool age independent of family characteristics and oral health behavior at 5 years of age. The results indicate that early established habits regarding tooth brushing and consumption of sugary drinks have long term effects on caries development. Parents encountering difficulties in establishing favorable oral health behavior in children’s first years of life should receive special attention from health personnel. PMID:25385683

    We deployed a network targeting acoustic emissions (AEs) down to Mw~ -5 at 1-km depth in the Cooke 4 mine in South Africa as a part of a 5-year project called "Observational Studies in South African Mines to Mitigate Seismic Risks." This network of 30 sensors spans ~100 m, and collected waveform data for more than 4.5-million triggers in 5 years. We provide an overview of the main findings. 1) Naoi et al. (2015; Pageoph) reported that 90% of observed AEs aggregated along the advancing mining front. Their size distribution obeyed the Gutenberg-Richter law down to Mw -4, and their b-values were invariant with time from blasting, contradicting a previous study. 2) Moriya et al. (under review) showed that this AE aggregation consists of several tabular clusters, which were formed regularly as the mining front advanced. Although large earthquakes (Mw > 1) were not found, the clusters likely represent the preparation process of large shear fracture events because their geometry resembles large shear fractures, known by in-situ wall-rock observation, which formed concurrently with large seismic events. 3) Naoi et al. (2015; Tectonophysics) reported that the remaining 10% of AEs exhibit very sharp, planar distributions, with high b-values. They are likely events located on pre-existing geological faults loaded by mining-induced stresses. Such on-fault events are rare for intraplate faults, where microseismic events generally occur in the surrounding region. 4) Naoi et al. (2015; JGR) found planar clusters that newly emerged ahead of a mining front and gradually expanded to 20 m. They likely represent the evolution of a slow-slip patch on a pre-existing fault. The b-value of those AEs decreased drastically from 2.5 to 1.5, consistent with stress buildup by the approaching mining front.

    2014-12-01

    This study aimed to measure the effects of ecological restoration on blanket peat water table depths, DOC concentrations and CO2 fluxes. In April 2003 the Bleaklow Plateau, an extensive area of deep blanket peat in the Peak District National Park, northern England, was devegetated by a wildfire. As a result the area was selected for large scale restoration. In this study we considered a 5-year study of four restored sites in comparison to both an unrestored, bare peat control and to vegetated control that did not require restoration. Results suggested that sites with revegetation alongside slope stabilisation had the highest rates of photosynthesis and were the largest net (daylight hours) sinks of CO2. Bare sites were the largest net sources of CO2 and had the deepest water table depths. Sites with gully wall stabilisation were between 5-8 times more likely to be net CO2 sinks than the bare sites. Revegetation without gully flow blocking using plastic dams did not have a large effect on water table depths in and around the gullies investigated whereas a blocked gully had water table depths comparable to a naturally revegetating gully. A ten centimetre lowering in water table depth decreased the probability of observing a net CO2 sink, on a given site, by up to 30%. With respect to DOC the study showed that the average soil porewater DOC concentration on the restored sites rose significantly over the 5 year study representing a 34% increase relative to the vegetated control and an 11% increase relative to the unrestored, bare control. Soil pore water concentrations were not significantly different from surface runoff DOC concentrations and therefore restoration as conducted by this study would have contributed to water quality deterioration in the catchment. The most important conclusion of this research was that restoration interventions were apparently effective at increasing the likelihood of net CO2 sink behaviour and raising water tables on degraded

    2016-01-01

    Purpose The aim of the study was to describe a case of globally hyperpigmented torpedo maculopathy that also contained a novel central lesion resembling a ‘pseudo-lacuna’. We compare the morphology of the lesion after 5 years of follow-up. Case Presentation An asymptomatic 10-year-old Caucasian male was referred by his optometrist after having found a hyperpigmented lesion on routine dilated examination in 2010. Color fundus photography OS from October 2015 showed a 1.74 × 0.67 mm hyperpigmented oval-shaped lesion temporal to the macula. Since June 2010, the hyperpigmented torpedo lesion appeared to have assumed a more ovoid shape and increased in size in the vertical axis. Centrally, there was a small pearlescent-colored pseudo-lacuna lesion that seemed to also have significantly increased in size since June 2010. Enhanced depth imaging optical coherence tomography of this pseudo-lacuna showed retinal pigment epithelium clumping and migration. Fundus autofluorescence revealed reduced autofluorescence of the torpedo lesion and marked hyperautofluorescence of the pseudo-lacuna. Fluorescein angiography shows no neovascular disease or leakage. Conclusion Torpedo maculopathy has been described previously as a hypopigmented, nonprogressive lesion of unknown etiology. The findings of global hyperpigmentation, pseudo-lacuna formation, and morphologic changes over time in this lesion challenge these classically held descriptions, and necessitate long-term follow-up with multimodal imaging.

    Introduction: The Disease Management Project Breast Cancer (DMP Breast Cancer) was first launched in Hesse in 2004. The project is supported by the health insurance companies in Hesse and the Professional Association of Gynaecologists in Hesse. The aim is to offer structured treatment programmes to all women diagnosed with breast cancer in Hesse by creating intersectoral cooperations between coordinating clinics, associated hospitals and gynaecologists in private practice who registered in the DMP programme. Method: Between 1 January 2005 and 30 June 2011, 13 973 women were enrolled in the DMP programme. Results: After data cleansing, survival rates were calculated for a total of 11 214 women. The 5-year overall survival (OS) rate was 86.3 %; survival rates according to tumour stage on presentation were 92.2 % (pT1) and 82.3 % (pT2), respectively. The impact of steroid hormone receptor status on survival (87.8 % for receptor-positive cancers vs. 78.9 % for receptor-negative cancers) and of age at first diagnosis on survival (≤ 35 years = 91 %) were calculated. Conclusion: The project showed that intersectoral cooperation led to significant improvements in the quality of treatment over time, as measured by quality indicators and outcomes after treatment.

    Objective To examine child behavioral and cognitive outcomes after prenatal exposure to methamphetamine. Study design 412 mother-infant pairs (204 methamphetamine-exposed and 208 unexposed matched comparisons) were enrolled in the Infant Development, Environment and Lifestyle (IDEAL) study. The 151 children exposed to methamphetamine and 147 comparisons who attended the 7.5 year visit were included. Exposure was determined by maternal self-report and/or positive meconium toxicology. Maternal interviews assessed behavioral and cognitive outcomes using the Conner’s Parent Rating Scale – Revised: Short Form (CPRS-R:S). Results After adjusting for covariates, children exposed to methamphetamine had significantly higher cognitive problems subscale scores than comparisons and were 2.8 times more likely to have cognitive problems scores that were above average on the CPRS-R:S No association between prenatal methamphetamine exposure and behavioral problems, measured by the oppositional, hyperactivity and ADHD Index subscales, were found. Conclusion Prenatal methamphetamine exposure was associated with increased cognitive problems which may impact academic achievement and lead to increased negative behavioral outcomes. PMID:24630350

    We report upon the design, content and feedback from an interactive, experiential series of Workshops in Healing for senior medical students. Fifty-six final year medical students enrolled in 2×3 h workshops designed around the core themes of ‘physician know thyself’ (Workshop 1) and ‘confronting suffering’ (Workshop 2). Of the 56 students who initially enrolled, 48 students completed both workshops and provided a written open-ended reflection of their learning experience. The study, undertaken over a consecutive 5-year period (2008–2012), employed an emergent, qualitative design using thematic analysis of the reflective comments. We found that the design and content of both workshops promoted transformative learning for these final year medical students. Students identified the following benefits: (1) the opportunity to reaffirm their commitment to their chosen career path; (2) the value of listening to other students share their stories; (3) the importance of the timing of the workshops to occur after exams; (4) the use of various mediums such as art, poetry, music and contemporary/classic literature to present concepts of suffering and healing; and (5) the creation of a safe and confidential space. Students reported that these innovative workshops gave them a renewed sense of drive and enthusiasm for their chosen career. They highlighted the importance of addressing an aspect of medicine (healing) not covered in the traditional medical curriculum. Workshops in Healing helped them to rediscover a deeper meaning to medicine and their roles as future healthcare professionals. PMID:24473159

    Background. Short implants have become popular in the reconstruction of jaws, especially in cases with limited bone height. Shorter implants, those with locking tapers and plateau root shapes, tend to have longer survival times. We retrospectively investigated the cumulative survival rates of Bicon short implants (<8 mm) according to patient variables over a 5-year period. Materials and Methods. This study included 111 consecutively treated patients with 371 implants supporting fixed or removable prosthetics. Data were evaluated to acquire cumulative survival rates according to gender, age, tobacco use, surgical procedure, bone quality, and restoration type. Statistics were performed using chi-square, Mann-Whitney, and Kruskal Wallis H tests. Results. The survival rate was 97.3% with, on average, 22.8 months of follow-up. Patients older than 60 years had higher failure rate than the other age groups (P < 0.05). Placed region, age, and bone quality had adverse effects on survival rate in the <8 mm implant group with statistically significant difference (P < 0.05). Conclusions. Approximately 23-month follow-up data indicate that short implants with locking tapers and plateau-type roots have comparable survival rates as other types of dental implants. However, due to limitations of study, these issues remain to be further investigated in future randomized controlled clinical trials. PMID:25961004

    TALNET is a project aiming to systematically identify and work with gifted youth (13-19 years). Specifically, it applies online educational activities combined with face to face activities. It has been organised by the Faculty of Maths and Physics (MFF) of Charles University in Prague (UK) and National Institute for Youth (NIDM) since 2003, later in cooperation with other faculties, e.g. Natural Sciences (PrF UK), universities and science and research institutes in the Czech Republic and abroad, e.g. DLR, Germany. Topics of the educational activities come from natural sciences (such as physics, astronomy, biology, chemistry, meteorology etc.) and mathematics. The presented project's part METEO embraces lessons primarily focused on basics of meteorology and atmospheric physics in general and it has been part of the Talnet project for 5 years. The meteorological lectures consist of description of, e.g., climate system, meteorological quantities, weather forecasting, ozone and the stratosphere, climate change or atmospheric optics. On top of the lectures, the students are encouraged to work on enclosed homework such as meteorological time series analysis, clouds observation and classification, halo simulation and so on. The METEO course lasts one semester and the students make their seminar thesis at the end. The presented materials will consist of examples of the contemporary lectures and their organization, homeworks or seminar theses.

    Rivers are replenished by precipitation that works its way through watersheds and into stream networks. The time that precipitation requires to travel into a stream regulates contaminant transports, nutrient mobility and bedrock weathering, but has not yet been evaluated at a continental scale. Here we synthesize a pan-U.S.A. dataset of rain, snow and streamflow 18O/16O and 2H/1H ratios and analyze the data to show that the lion's share of USA streamflow is generated by precipitation that takes ~2 months to ~2.5 years to flush through watersheds and into networks of streams (i.e., rivers replenished by "infant-to-toddler aged" precipitation). These streamflow ages are considerably shorter than the average amount of time that water spends within streams themselves (~1 month, globally), and much shorter than the global groundwater residence time of more than ~1000 years. We also estimate the depth of "dynamic" groundwater storage that actively generates the majority of streamflow and discover that less than ~1% of watershed flowpaths generate the bulk of continental runoff. Our finding showcases that the most hydrologically-active zone within Earth's hydrosphere is located nearest to the surface where atmosphere-biosphere-lithosphere interactions are at a maximum. This research emphasizes the importance of critical zone research for developing accurate forecasts of how human modifications to the land and climate will impact downstream water, nutrient and contaminant fluxes.

  7. Measuring Replicative Life Span in the Budding Yeast

    Aging is a degenerative process characterized by a progressive deterioration of cellular components and organelles resulting in mortality. The budding yeast Saccharomyces cerevisiae has been used extensively to study the biology of aging, and several determinants of yeast longevity have been shown to be conserved in multicellular eukaryotes, including worms, flies, and mice 1. Due to the lack of easily quantified age-associated phenotypes, aging in yeast has been assayed almost exclusively by measuring the life span of cells in different contexts, with two different life span paradigms in common usage 2. Chronological life span refers to the length of time that a mother cell can survive in a non-dividing, quiescence-like state, and is proposed to serve as a model for aging of post-mitotic cells in multicellular eukaryotes. Replicative life span, in contrast, refers the number of daughter cells produced by a mother cell prior to senescence, and is thought to provide a model of aging in mitotically active cells. Here we present a generalized protocol for measuring the replicative life span of budding yeast mother cells. The goal of the replicative life span assay is to determine how many times each mother cell buds. The mother and daughter cells can be easily differentiated by an experienced researcher using a standard light microscope (total magnification 160X), such as the Zeiss Axioscope 40 or another comparable model. Physical separation of daughter cells from mother cells is achieved using a manual micromanipulator equipped with a fiber-optic needle. Typical laboratory yeast strains produce 20-30 daughter cells per mother and one life span experiment requires 2-3 weeks. PMID:19556967

  8. Life span in online communities

    Recently online communities have attracted great interest and have become an important medium of information exchange between users. The aim of this work is to introduce a simple model of the evolution of online communities. This model describes (a) the time evolution of users’ activity in a web service, e.g., the time evolution of the number of online friends or written posts, (b) the time evolution of the degree distribution of a social network, and (c) the time evolution of the number of active users of a web service. In the second part of the paper we investigate the influence of the users’ lifespan (i.e., the total time in which they are active in an online community) on the process of rumor propagation in evolving social networks. Viral marketing is an important application of such method of information propagation.

  9. 5 years of continuous seismic monitoring of snowmelt cycles in a Pyrenean valley

    NASA Astrophysics Data System (ADS)

    Diaz, Jordi; Sánchez-Pastor, Pilar; Gallart, Josep

    2016-04-01

    In recent years the analysis of background seismic noise variations in the proximity of river channels has revealed as a useful tool to monitor river flow, even for modest discharges. We will focus here in the application of this methodology to study the snowmelt cycle in an Pyrenean valley during the last 5 years, using data from the seismic geophysical station located inside the Canfranc Underground Laboratory (Central Pyrenees). Diaz et al. (2014) first identified in the seismic data the signature of river flow increases associated to snowmelt episodes in the catchment area of the Aragon River, based on the marked correlation between the seismic energy variations in the 2-8 Hz frequency band and the estimated variations in water resources from snowfall. The analysis of seismic data during the snowmelt periods allows to identify a clear 24h cycle, with energy increasing from about 14:00 GMT, remaining at a relatively high level for 12 hours and then smoothly vanishing. The spectrogram reveals richer information, as clear variations in the frequency content can be detected during the time intervals in which the amplitude of the seismic signal remains constant. The data available so far allow to compare the evolution of snowmelt in five seasons with very different hydrological behavior. The 2011 and 2012 seasons have been dry, with snow volumes 30-50 % beneath the average values, while the 2013, 2014 and in particular the 2015 seasons have been largely above the mean. Those variations are reflected in the seismic data, which allow to monitor the time occurrence of the main snowmelt stages for each season and to estimate the intensity of the different snowmelt episodes. Therefore, seismic data can be useful for long term monitoring of snowmelt in Alpine-style mountains.

    The purpose of this study was to determine colour changes in a composite cured with tungsten-halogen, light-emitting diode (LED) or a plasma arc after 5 years. Five specimens 10 mm in diameter and 2 mm in height were prepared using Hybrid (Clearfil AP-X) composite for each test group. The corresponding specimens were cured with a tungsten-halogen curing light, a LED unit or with a plasma arc. Specimens were stored in light-proof boxes for 5 years after the curing procedure to avoid further exposure to light and stored in 37 degrees C in 100% humidity. Colorimetric values of the specimens immediately after curing and after 5 years were measured using colorimeter. The DeltaE*( ab ) values varied significantly depending on the curing unit used (p < 0.001). Curing time did not affect the colour changes of the specimens (p = 0.4). The results of this study suggest that composite materials undergo measurable changes due to the curing unit exposure. PMID:18769947

    2014-11-01

    There is presently a great interest in the therapeutic potential of agmatine, decarboxylated arginine, for various diseases. Recent clinical studies have already shown that oral agmatine sulfate given for up to 3 weeks provides a safe and, as compared with current therapeutics, more effective treatment for neuropathic pain. These studies have ushered in the use of dietary agmatine as a nutraceutical. However, in view of information paucity, assessment of long-term safety of oral agmatine treatment is now clearly required. The authors of this report undertook to assess their own health status during ongoing consumption of a high daily dosage of oral agmatine over a period of 4-5 years. A daily dose of 2.67 g agmatine sulfate was encapsulated in gelatin capsules; the regimen consists of six capsules daily, each containing 445 mg, three in the morning and three in the evening after meals. Clinical follow-up consists of periodic physical examinations and laboratory blood and urine analyses. All measurements thus far remain within normal values and good general health status is sustained throughout the study period, up to 5 years. This case study shows for the first time that the recommended high dosage of agmatine may be consumed for at least 5 years without evidence of any adverse effects. These initial findings are highly important as they provide significant evidence for the extended long-term safety of a high daily dosage of dietary agmatine--a cardinal advantage for its utility as a nutraceutical.

    2016-03-01

    A method is presented for computing the number of spanning trees involving one link or a specified group of links, and excluding another link or a specified group of links, in a network described by a simple graph in terms of derivatives of the spanning-tree generating function defined with respect to the eigenvalues of the Kirchhoff (weighted Laplacian) matrix. The method is applied to deduce the node degree distribution in a complete or randomized set of spanning trees of an arbitrary network. An important feature of the proposed method is that the explicit construction of spanning trees is not required. It is shown that the node degree distribution in the spanning trees of the complete network is described by the binomial distribution. Numerical results are presented for the node degree distribution in square, triangular, and honeycomb lattices.

    Radiologically inserted gastrostomy (RIG) is an established way of maintaining enteral nutrition in patients who cannot maintain nutrition orally. The purpose of this study was to evaluate the safety and efficacy of primary placement of a wide bore button gastrostomy in a large, varied patient population through retrospective review. All patients who underwent gastrostomy placement from January 1, 2004 to January 1, 2009 were identified. 18-Fr gastrostomy buttons (MIC-Key G) were inserted in the majority. Follow-up ranged from 6 months to 4.5 years. A total of 260 patients (M:F 140:120, average age 59.2 years) underwent gastrostomy during the study period. Overall success rate for RIG placement was 99.6 %, with success rate of 95.3 % for primary button insertion. Indications included neurological disorders (70 %), esophageal/head and neck malignancy (21 %), and other indications (9 %). Major and minor complication rates were 1.2 and 12.8 %, respectively. Thirty-day mortality rate was 6.8 %. One third of patients underwent gastrostomy reinsertion during the study period, the main indication for which was inadvertent catheter removal. Patency rate was high at 99.5 %. The maximum number of procedures in any patient was 8 (n = 2), and the average tube dwell time was 125 days. Primary radiological insertion of a wide bore button gastrostomy is a safe technique, with high success rate, high patency rate, and low major complication rate. We believe that it is feasible to attempt button gastrostomy placement in all patients, once tract length is within limits of tube length. If difficulty is encountered, then a standard tube may simply be placed instead.

    Background: To determine the outcome of hypospadias repair in children. Patients and Methods: This was a retrospective study of all patients with hypospadias managed at the University of Abuja Teaching Hospital, Abuja, Nigeria from January 2009 to December 2013. Results: Twenty-four cases of hypospadias had corrective surgery during the 5-year period under review. Seventy-five percent of the patients (n = 18) were seen after the 1st year of life. There were two peaks of ages at corrective repair; 45.8% between age 1 and 3 years and 29.1% between age 5 and 10 years. The average age at time of surgery was 44.9 months. Distal hypospadias were more common (58.4%), followed by glanular (20.8%) and proximal (20.8%) hypospadias. Associated anomalies included chordee, maldescended testicles and inguinal hernia in 20.8%, 4.1% and 8.3% cases, respectively. Operative techniques were single-stage procedures in 79.1% of patients consisting of simple circumcision in two cases (10.5%), Mathieu's peri-meatal based flap in four cases (21%), meatal advancement and glanuloplasty incorporated in three cases (16%) and Snodgrass tubularised incised urethral plate tubularised incised plate in 10 cases (52.5%). The remaining 20.9% (n = 5) had multi-staged procedures. The most common post-operative complications were urethrocutenous fistula in nine patients (33.3%) and metal stenosis in 3 patients (12.5%). Conclusions: Our results show that hypospadia repair is froth with attendant high complications in our setting. PMID:25659549

    Purpose: Evaluate efficacy and toxicity of salvage high-dose-rate brachytherapy (HDRB) for locally recurrent prostate cancer after definitive radiation therapy (RT). Methods and Materials: We retrospectively analyzed 52 consecutively accrued patients undergoing salvage HDRB between 1998 and 2009 for locally recurrent prostate cancer after previous definitive RT. After pathologic confirmation of locally recurrent disease, patients received 36 Gy in 6 fractions. Twenty-four patients received neoadjuvant hormonal therapy before salvage, and no patients received adjuvant hormonal therapy. Determination of biochemical failure after salvage HDRB was based on the Phoenix definition. Overall survival (OS) and bF distributions were calculated using the Kaplan-Meier method. Univariate analyses were performed to identify predictors of biochemical control. Acute and late genitourinary (GU) and gastrointestinal (GI) toxicities, based on Common Terminology Criteria for Adverse Events (version 4), were documented. Results: Median follow-up after salvage HDRB was 59.6 months. The 5-year OS estimate was 92% (95% confidence interval [CI]: 80%-97%) with median survival not yet reached. Five-year biochemical control after salvage was 51% (95% CI: 34%-66%). Median PSA nadir postsalvage was 0.1 (range: 0-7.2) reached at a median of 10.2 months after completing HDRB. As for complications, acute and late grade 3 GU toxicities were observed in only 2% and 2%, respectively. No grade 2 or higher acute GI events and 4% grade 2 GI late events were observed. On univariate analysis, disease-free interval after initial definitive RT (P=.07), percent of positive cores at the time of diagnosis (P=.08), interval from first recurrence to salvage HDRB (P=.09), and pre-HDRB prostate-specific antigen (P=.07) were each of borderline significance in predicting biochemical control after salvage HDRB. Conclusions: Prostate HDRB is an effective salvage modality with relatively few long-term toxicities. We

    Background The aim of the study was to examine the longitudinal change in quality of life components of patients with chronic obstructive pulmonary disease (COPD). Methods In the Hokkaido COPD Cohort Study, 261 subjects were appropriately treated and followed over 5 years with a 74% follow-up rate at the end. The longitudinal changes in St George’s Respiratory Questionnaire (SGRQ) scores were annually evaluated with forced expiratory volume in 1 second (FEV1). The subjects were classified into the rapid decliners, slow decliners, and sustainers based on ΔFEV1/year. Results The activity component of SGRQ generally deteriorated over time, and its annual decline was the greatest in the rapid decliners (<25th percentile). In contrast, the symptom component improved significantly year by year in the sustainers (>75 percentile), and it did not deteriorate even in the rapid decliners. Of the baseline data, predictors for worsening of the activity component were older age and lower body mass index. Larger reversibility was related to symptom component improvement. Of the follow-up data, ΔFEV1/year was the best predictor for worsening of the components of SGRQ. Continuous smoking was another factor for worsening of the activity component. For the symptom component, a history of exacerbation by admission definition was the determinant of its deterioration, whereas use of beta agonists was related to improvement. Conclusion The longitudinal changes of quality of life and their determinants are markedly different and independent between its components. The activity component of SGRQ generally deteriorated over years, while the symptom component rather improved in some patients with COPD under appropriate treatment. PMID:25914531

    The objective of this article is to evaluate the role of computed tomography (CT) in a pregnant patient with right lower quadrant pain in whom there was a clinical suspicion of acute appendicitis. During a 5-year period the clinical records of all pregnant women who underwent imaging examination for clinically suspected appendicitis were reviewed. The imaging findings were correlated with patient management and final outcome. Thirty-nine pregnant patients were referred for imaging, of which 35 underwent initial evaluation with sonography, 23 of these women underwent a computed tomographic examination, and an additional 4 patients were directly imaged with CT without earlier sonographic assessment. Surgery confirmed appendicitis in all 5 patients who were operated on on the basis of findings of appendicitis on a CT scan. Two patients underwent surgery based on an alternate diagnosis suggested preoperatively (tubal torsion = 1, ovarian torsion = 1). All patients with negative findings at CT had an uneventful clinical course. In those patients who were evaluated only with ultrasound, a diagnosis of appendicitis was missed in 5 patients. The sensitivity of CT in the diagnosis of appendicitis in our study group was 100%, compared with a sensitivity of 46.1% for ultrasound. CT provides an accurate diagnosis in patients suspected to have acute appendicitis and is of value in avoiding false negative exploratory laparatomy with its consequent risk of maternal and fetal mortality and morbidity. Although sonography is the preferred initial imaging modality as its lack of ionizing radiation, CT is more accurate in providing a timely diagnosis and its use is justified to reduce maternal mortality and mortality in patients with appendicitis.

    Introduction Ovarian cancer is the second most common malignancy in women, the most common cause of gynecologic cancer deaths, and most patients have advanced stage disease at the time of diagnosis. The purpose of this study was to estimate the 5-year survival of patients with epithelial ovarian cancer based on age, tumor histology, stage of disease, and type of treatment. Methods This study was conducted on 120 patients with epithelial ovarian cancer referred to Shahid Sadoughi hospital and Shah Vali oncology clinic of Yazd from 2006 to 2012. Demographic data and patient records were studied to evaluate the treatment outcome, pathology of the tumor, and stage of disease. Finally, the overall survival rate and tumor-free survival of patients was assessed. Results The mean patient age was 53.87± 14.11 years. Most participants had stage I (36.7%) or stage II (35%) disease. Serous adenocarcinoma (57.6%) was the most common pathology found in patients with epithelial ovarian cancer. The overall survival of patients in this study was significantly associated with the histological tumor type (p = 0.000) and disease stage (p = 0.0377). Stage I (84.18%) and serous adenocarcinoma (72.81%) demonstrated the best survival. The tumor-free survival rates were not associated with histology types (p = 0.079), surgical procedure (p = 0.18), or chemotherapy (p = 0.18). Conclusion The survival of patients with epithelial ovarian cancer was significantly associated with disease stage. Serous adenocarcinoma also had the best prognosis among the pathologies studied. Therefore, early detection of ovarian cancer can substantially increase the survival rate. PMID:26516450

    To investigate the 5-year mortality of patients undergoing maintenance hemo-dialysis (HD) at Al-Shat center Tripoli, we reviewed during June 2007 the records of all the HD patients initiated on HD from Jun 2000 and Jan 2002. There were 124 patients in the study, 77 males (63.6%) and 47 (36.4%) females, with a mean age of 49 +/- 14 years. Diabetic nephropathy (DN) was the underlying kidney disease in 34 (27.4%) patients. After 5 years; 3 patients were transferred to other centers, 18 (14.9%) patients underwent kidney transplan-tation. Out of the 103 patients who continued on hemodialysis, 53 (51.4%) expired during the 5-year follow-up. Mortality was associated with older age (p 50 years) and DN (p< 0.002 and OR of 3.9). Mortality rate in diabetics was 74.1% and significantly associated with male sex (p< 0.0067 and OR of 2.4), older age (p< 0.004), presence of hypertension (p< 0.003 and OR of 3.9), type 1 diabetes (OR 1.6), and elevated mean body weight (p< 0.046). Mortality was also relatively higher in black patients (OR of 2.0) and smokers (OR of 1.39). In conclusion, the overall 5- year mortality for dialysis patients was elevated and higher in the diabetics. PMID:18310882

    The potential for sexual conflict to influence the evolution of life span and aging has been recognized for more than a decade, and recent work also suggests that variation in life span and aging can influence sexually antagonistic coevolution. However, empirical exploration of these ideas is only beginning. Here, we provide an overview of the ideas and evidence linking inter- and intralocus sexual conflicts with life span and aging. We aim to clarify the conceptual basis of this research program, examine the current state of knowledge, and suggest key questions for further investigation. PMID:24938876

    Background Technological advances have made it easier for researchers to collect more frequent longitudinal data from survey respondents via personal computers, smartphones, and other mobile devices. Although technology has led to an increase in data-intensive longitudinal studies, little is known about attrition from such studies or the differences between respondents who complete frequently administered surveys in a timely manner, and respondents who do not. Objective We examined respondent characteristics and behaviors associated with continued and on-time participation in a population-based intensive longitudinal study, using weekly web-based survey interviews over an extended period. Methods We analyzed data from the Relationship Dynamics and Social Life study, an intensive longitudinal study that collected weekly web-based survey interviews for 2.5 years from 1003 18- and 19-year-olds to investigate factors shaping the dynamics of their sexual behavior, contraceptive use, and pregnancies. Results Ordinary least squares and logistic regression analyses showed background respondent characteristics measured at baseline were associated with the number of days respondents remained enrolled in the study, the number of interviews they completed, and the odds that they were late completing interviews. In addition, we found that changes in pregnancy-related behaviors reported in the weekly interviews were associated with late completion of interviews. Specifically, after controlling for sociodemographic, personality, contact information, and prior experience variables, we found that weekly reports such as starting to have sex (odds ratio [OR] 1.17, 95% CI 1.03-1.32, P=.01), getting a new partner (OR 1.76, 95% CI 1.53-2.03, P<.001), stopping the use of contraception (OR 1.28, 95% CI 1.10-1.49, P=.001), and having a new pregnancy (OR 5.57, 95% CI 4.26-7.29, P<.001) were significantly associated with late survey completion.

    Radionuclides were added to the anoxic hypolimnion of a Canadian Shield lake to simulate the nuclear fuel waste disposal scenario where radionuclides might enter the bottom waters of a lake. The radionuclides remained in the hypolimnion until lake mixing at autumn turnover after which 60Co was rapidly lost and 134Cs was slowly lost from the water. Only 0.4% of the 60Co and 0.6% of the 134Cs remained in the water at year 5. Highest concentrations occurred in periphyton and filter feeders, Holopedium gibberum and clams (Anodonata grandis grandis). From maximum annual concentrations in clam tissues, it was estimated that the availability of 60Co for uptake had a half-time (t1/2) of 835 days in the lake, whereas that for 134Cs was 780 days. Loss rate coefficients, k, for the radionuclides from taxa ranged from 0.0008 to 0.0043 day-1 (t1/2 = 161-866 days) for 60Co and from 0.0009 to 0.005 day-1 (t1/2 = 139-770 days) for 134Cs. Cobalt-60 concentrations in forage fish were low, whereas 134Cs concentrations increased over the first year or two, then slowly declined. On the basis of k values measured for forage fish, the biological half-time of 134Cs in forage fish ranged from 428 to 630 days. Maximum 134Cs concentrations in forage fish were higher following hypolimnetic addition than epilimnetic addition. Relatively high 134Cs concentrations in periphyton at year 5 point to the importance of benthic pathways in the recycling of contaminants to higher trophic levels. The presence of 134Cs in biota 5 years after the addition, long after concentrations were no longer detectable in surface waters, is evidence of the persistence of Cs in aquatic systems. The k values (or t1/2 values) for the loss of 60Co and 134Cs from water and their uptake and loss from biota can be used to establish parameter values for assessment models. The results demonstrate that assessment models should account for the release of radionuclides from sediment and their subsequent recycling in the food

    Since main sequence stars appear to increase their burning rate as they age, the sun may be thought to have increased its output by 30% since the earth's origin 4.5 billion years ago. Due to the requirement for some means of planetary thermostasis in the maintenance of an equable climate since life began, possible links are considered between the biological, Gaia hypothesis of Lovelock and Margulis (1974) for climate control, and Walker et al's (in press) model of automatic thermostasis, in which the abundance of such atmospheric greenhouse gases as CO2 adjusts to resist the warming tendency of the increased solar flux. It is concluded that, since atmospheric CO2 is now close to its partial pressure lower limit, the biosphere will on a geological time-scale be soon exposed, without protection, to the predicted solar luminosity increases.

    Background We combined hospital-based surveillance and health utilization survey data to estimate the incidence of respiratory viral infections associated hospitalization among children aged < 5 years in Bangladesh. Methods Surveillance physicians collected respiratory specimens from children aged <5 years hospitalized with respiratory illness and residing in the primary hospital catchment areas. We tested respiratory specimens for respiratory syncytial virus, parainfluenza viruses, human metapneumovirus, influenza, adenovirus and rhinoviruses using rRT-PCR. During 2013, we conducted a health utilization survey in the primary catchment areas of the hospitals to determine the proportion of all hospitalizations for respiratory illness among children aged <5 years at the surveillance hospitals during the preceding 12 months. We estimated the respiratory virus-specific incidence of hospitalization by dividing the estimated number of hospitalized children with a laboratory confirmed infection with a respiratory virus by the population aged <5 years of the catchment areas and adjusted for the proportion of children who were hospitalized at the surveillance hospitals. Results We estimated that the annual incidence per 1000 children (95% CI) of all cause associated respiratory hospitalization was 11.5 (10–12). The incidences per 1000 children (95% CI) per year for respiratory syncytial virus, parainfluenza, adenovirus, human metapneumovirus and influenza infections were 3(2–3), 0.5(0.4–0.8), 0.4 (0.3–0.6), 0.4 (0.3–0.6), and 0.4 (0.3–0.6) respectively. The incidences per 1000 children (95%CI) of rhinovirus-associated infections among hospitalized children were 5 (3–7), 2 (1–3), 1 (0.6–2), and 3 (2–4) in 2010, 2011, 2012 and 2013, respectively. Conclusion Our data suggest that respiratory viruses are associated with a substantial burden of hospitalization in children aged <5 years in Bangladesh. PMID:26840782

    Objective: We evaluated the "extended" long-term (5 years) functional outcomes in obstetric brachial plexus injury (OBPI) patients, who underwent triangle tilt surgery between February 2005 and January 2008. Methods: Twenty two children (9 girls and 13 boys, mean age at surgery was 5.8 years; ranging 2.1-11.8 years old), who initially presented with medial rotation contracture and scapula deformity secondary to obstetric brachial plexus injury were included in this study. Functional movements were evaluated pre-operatively, and 5 years following triangle tilt surgery by modified Mallet scale. Results: Here, we report long-term (5 years) follow-up of triangle tilt surgery for 22 OBPI patients. Upper extremity functional movements such as, external rotation (2.5±0.6 to 4.1±0.8, p<0.0001), hand-to-spine (2.6±0.6 to 3.4±1.1, p<0.005), hand-to-neck (2.7±0.7 to 4.3±0.7, p<0.0001), hand-to-mouth (2.3±0.9 (92º±33) to 4.2±0.5 (21º±16), p<0.0001), and supination (2.6±1.1 (-8.2º ±51) to 4.1±0.7 (61±32)) were significantly improved (p<0.0001), and maintained over the extended long-term (5 years). Total modified Mallet functional score was also shown to improve from 14.1±2.7 to 20.3±2.5. Conclusions: The triangle tilt surgery improved all shoulder functions significantly, and maintained over the extended long-term (5 years) in these patients. PMID:23730369

  19. 5 year radar-based rainfall statistics: disturbances analysis and development of a post-correction scheme for the German radar composite

    Wagner, A.; Seltmann, J.; Kunstmann, H.

    2015-02-01

    A radar-based rainfall statistic demands high quality data that provide realistic precipitation amounts in space and time. Instead of correcting single radar images, we developed a post-correction scheme for long-term composite radar data that corrects corrupted areas, but preserves the original precipitation patterns. The post-correction scheme is based on a 5 year statistical analysis of radar composite data and its constituents. The accumulation of radar images reveals artificial effects that are not visible in the individual radar images. Some of them are already inherent to single radar data such as the effect of increasing beam height, beam blockage or clutter remnants. More artificial effects are introduced in the process of compositing such as sharp gradients at the boundaries of overlapping areas due to different beam heights and resolution. The cause of these disturbances, their behaviour with respect to reflectivity level, season or altitude is analysed based on time-series of two radar products: the single radar reflectivity product PX for each of the 16 radar systems of the German Meteorological Service (DWD) for the time span 2000 to 2006 and the radar composite product RX of DWD from 2005 through to 2009. These statistics result in additional quality information on radar data that is not available elsewhere. The resulting robust characteristics of disturbances, e.g. the dependency of the frequencies of occurrence of radar reflectivities on beam height, are then used as a basis for the post-correction algorithm. The scheme comprises corrections for shading effects and speckles, such as clutter remnants or overfiltering, as well as for systematic differences in frequencies of occurrence of radar reflectivities between the near and the far ranges of individual radar sites. An adjustment to rain gauges is also included. Applying this correction, the Root-Mean-Square-Error for the comparison of radar derived annual rain amounts with rain gauge data

    Purpose The Study of Progression of Adult Nearsightedness (SPAN) is a 5-year observational study to determine the risk factors associated with adult myopia progression. Candidate risk factors include: a high proportion of time spent performing near tasks, performing near tasks at a close distance, high accommodative convergence/accommodation (AC/A) ratio, and high accommodative lag. Methods Subjects between 25 and 35 years of age, with at least −0.50 D spherical equivalent of myopia (cycloplegic autorefraction), were recruited from the faculty and staff of The Ohio State University. Progression is defined as an increase in myopia of at least −0.75 D spherical equivalent as determined by cycloplegic autorefraction. Annual testing includes visual acuity, noncycloplegic autorefraction and autokeratometry, phoria, accommodative lag, response AC/A ratio, cycloplegic autorefraction, videophakometry, ultrasound, and partial coherence interferometry (IOLMaster). Participants’ near activities were assessed using the experience sampling method (ESM). Subjects carried a pager for two 1-week periods and were paged randomly throughout the day. Each time they were paged, they dialed into an automated telephone survey and reported their visual activity at that time. From these responses, the proportion of time spent performing near work was estimated. Results Three-hundred ninety-six subjects were enrolled in SPAN. The mean (± standard deviation) age at baseline was 30.7 ± 3.5 years, 66% were female, 80% were white, 11% were black, and 8% were Asian/Pacific Islander. The mean level of myopia (spherical equivalent) was −3.54 ± 1.77 D, the mean axial length by IOLMaster was 24.6 ± 1.1 mm, and subjects were 1.7 ± 4.0 Δ exophoric. Refractive error was associated with the number of myopic parents (F = 3.83, p = 0.023), and the number of myopic parents was associated with the age of myopia onset (χ2 = 13.78, p = 0.001). In a multivariate analysis, onset of myopia (early

    Changes to the chromatin structure accompany aging, but the molecular mechanisms underlying aging and the accompanying changes to the chromatin are unclear. Here, we report a mechanism whereby altering chromatin structure regulates life span. We show that normal aging is accompanied by a profound loss of histone proteins from the genome. Indeed, yeast lacking the histone chaperone Asf1 or acetylation of histone H3 on lysine 56 are short lived, and this appears to be at least partly due to their having decreased histone levels. Conversely, increasing the histone supply by inactivation of the histone information regulator (Hir) complex or overexpression of histones dramatically extends life span via a pathway that is distinct from previously known pathways of life span extension. This study indicates that maintenance of the fundamental chromatin structure is critical for slowing down the aging process and reveals that increasing the histone supply extends life span.

  2. Vertical distribution of the Saharan Air Layer from 5 years of CALIPSO observations

    NASA Astrophysics Data System (ADS)

    Tsamalis, C.; Chédin, A.

    2012-04-01

    The Saharan Air Layer (SAL) forms as dry and hot air moves across the Sahara desert. SAL, containing substantial amounts of mineral dust, is a dominant feature that influences the large scale environment from West Africa to eastern tropical America, inhibiting tropical cyclogenesis and Atlantic hurricane formation. Furthermore, SAL dust aerosols have a strong impact on the energy budget through the so-called direct and indirect effects. The SAL has been studied with dedicated campaigns at the two sides of the Atlantic or using space observations due to lack of systematic in situ measurements away from the continents. However the campaigns are restricted in time, while satellite observations of thermodynamic variables are affected by the presence of dust. Moreover, satellite measurements of aerosols, particularly in the visible, mostly provide column integrated properties like the optical depth, without information about the vertical distribution. On the other hand, new generation infrared sounders now bring reliable information on the dust layer mean altitude, but their new established results need further validation. However, the two-wavelength lidar CALIOP, launched on board CALIPSO in April 2006, permits an accurate determination of the aerosol vertical distribution, on a global scale. Thanks to depolarisation at 532 nm, CALIOP is able to discriminate between dust and other types of aerosols, which generally do not depolarize light. Here, the L2 5 km aerosol layer product (version 3.01) is used to calculate the vertical distribution of the dust aerosols above the Atlantic during the last 5 years (June 2006 - May 2011) with a horizontal resolution of 1 degree for the four seasons. More specifically, two classes of aerosols are used from the L2 product: dust and polluted dust, in order to take into account the change of dust aerosols optical properties with transport. Results show the latitudinal displacement of the SAL between winter [-5, 15]°N and summer [10

    After surgery for trauma or correction of congenital anomaly, hand function is difficult to evaluate in children because there are no reference norms on children 3 to 5 years old. The purpose of this study was to determine whether reproducible normative values for hand dexterity and grip and pinch strength could be obtained in young children using simple tests that could be administered quickly within the attention span of a 3- to 5-year-old. The Functional Dexterity Test (FDT), a pegboard test validated for adults and older children, seemed to meet our requirements for dexterity. The FDT was administered to a convenience sample of normal children in a prekindergarten school who were grouped according to age: 3-year-olds (n = 17), 4-year-olds (n = 24), and 5-year-olds (n = 22). Hand dominance was determined. The task was demonstrated by 1 of the 2 testers. The child was asked to turn the pegs over in the pegboard without using the free hand or balancing the peg against the chest. Both hands were tested. Grip and pinch strengths were measured in both hands in a consistent manner. All the children were tested with the arm at the side and the elbow at 90 degrees. A dynamometer was used for grip strength and a pinch meter was used to measure key (lateral) and tripod pinch strengths. Means and SDs were calculated for each age group, and the dependent values of dexterity, strength, and dominance were correlated. Dexterity and strength scores were significantly different by age group. A good FDT score in the dominant hand was predictive of a good score in the nondominant hand. Grip and pinch strength correlated poorly with functional dexterity. The normative values established in this study for children in the 3- to 5-year-old range can be referenced for disability estimates and establishing goals for children after surgery or hand injury.

    Many children younger than 5 years in developing countries are exposed to multiple risks, including poverty, malnutrition, poor health, and unstimulating home environments, which detrimentally affect their cognitive, motor, and social-emotional development. There are few national statistics on the development of young children in developing countries. We therefore identified two factors with available worldwide data--the prevalence of early childhood stunting and the number of people living in absolute poverty--to use as indicators of poor development. We show that both indicators are closely associated with poor cognitive and educational performance in children and use them to estimate that over 200 million children under 5 years are not fulfilling their developmental potential. Most of these children live in south Asia and sub-Saharan Africa. These disadvantaged children are likely to do poorly in school and subsequently have low incomes, high fertility, and provide poor care for their children, thus contributing to the intergenerational transmission of poverty.

    Generalized aggressive periodontitis (GAgP) is a distinct type of periodontal disease associated with considerably more rapid periodontal tissue destruction than chronic periodontitis. This study presents the 5-year follow-up of a patient with GAgP. A 29-year-old man reported experiencing increasing gingival recession. He was treated using cause-related therapy, provisional splints, and flap surgery combined with allograft grafting and was followed up for 5 years. This case study shows that elimination of infectious microorganisms and meticulous long-term maintenance provide an effective treatment modality for aggressive periodontitis cases. This treatment modality can restore the masticatory function and provide the GAgP patient with improved quality of life. PMID:25909527

    2010-08-01

    In the 5-year WMAP data analysis, a new parametrization form for dark energy equation-of-state was used, and it has been shown that the equation-of-state, w(z), crosses the cosmological-constant boundary w = -1. Based on this observation, in this paper, we investigate the reconstruction of quintom dark energy model. As a single-real-scalarfield model of dark energy, the generalized ghost condensate model provides us with a successful mechanism for realizing the quintom-like behavior. Therefore, we reconstruct this scalar-field quintom dark energy model from the WMAP 5-year observational results. As a comparison, we also discuss the quintom reconstruction based on other specific dark energy ansatzs, such as the CPL parametrization and the holographic dark energy scenarios.

    2016-07-01

    The purpose of this case report is to present a rare finding of synovial sarcoma in a 5-year-old child. Most soft-tissue masses of the foot are too often presumed to be small and benign; therefore, compared with soft-tissue sarcomas, they are difficult to clinically differentiate and treat. A 5-year-old girl presented with a painful lesion that was diagnosed as synovial sarcoma after an excisional biopsy was performed. This was an unexpected finding of synovial sarcoma involving the tibialis posterior tendon of her right foot. The patient presented with an 8-month history of tenderness and an antalgic gait. We would like to encourage that all soft-tissue tumors of the foot be preoperatively evaluated with the aid of diagnostic imaging so that a well-planned biopsy assessment can be performed, with adequate margins excised.

    The World Health Organization recommends that before lymphatic filariasis elimination in an area can be confirmed, an additional survey should be performed at least 5 years after stopping mass drug administration. The current study aimed to determine the status of lymphatic filariasis 5 years after cessation ofthe mass drug administration in 3 sentinel Egyptian villages in Menoufiya Governorate. The rapid immunochromatographic card test (ICT) and a new commercial antibody detection kit (CELISA®) were used. All 1321 primary-school children aged 6-7 years old were ICT negative but 27 children were antibody positive. All households surveyed in one village with the highest antibody prevalence were ICT negative, indicating an absence of lymphatic filariasis. The CELISA antibody kit needs more standardization and development to be useful under field conditions. We conclude that lymphatic filariasis is no longer a public health problem in these villages and other villages with similar epidemiological conditions. PMID:24952286

    The purpose of the study was to determine whether mothers’ adversities experienced during early pregnancy are associated with offspring’s autonomic nervous system (ANS) reactivity trajectories from 6 months to 5 years of age. This cohort study of primarily Latino families included maternal interviews at 13–14 weeks gestation about their experience of a range of adversities: father’s absence, general social support, poverty level, and household density. ANS measures of heart rate, respiratory sinus arrhythmia (parasympathetic nervous system) and preejection period (sympathetic nervous system) were collected during resting and challenging conditions on children at 6 months and 1, 3.5 and 5 years of age. Reactivity measures were calculated as the mean of the responses to challenging conditions minus a resting condition. Fixed effects models were conducted for the 212 children with two or more timepoints of ANS measures. Interactions between maternal prenatal adversity levels and child age at time of ANS protocol were included in the models, allowing the calculation of separate trajectories or slopes for each level of adversity. Results showed no significant relations between mothers’ prenatal socioeconomic or social support adversity and offspring’s parasympathetic nervous system trajectories, but there was a statistically significant relationship between social support adversity and offspring’s heart rate trajectories (p<.05) and a borderline significant relationship between socioeconomic adversity and offspring’s sympathetic nervous system trajectories (p = .05). Children whose mothers experienced one, not two, social support adversity had the smallest increases in heart rate reactivity compared to children whose mothers experienced no adversity. The children whose mothers experienced no social support and no socioeconomic adversity had the largest increases in heart rate and preejection period respectively from 6 months to 5 years showing the

    Objectives To determine if odor identification ability is associated with the 5-year incidence of cognitive impairment in a large population of older adults with normal cognition at baseline and if olfactory impairment contributes to the prediction of cognitive decline in a population. Design Population-based longitudinal study. Setting Beaver Dam, WI. Participants 1920 participants in the Epidemiology of Hearing Loss Study (mean age = 66.9 years). Measurements Olfaction was measured by the San Diego Odor Identification Test (SDOIT). Incident cognitive impairment was defined as a Mini-Mental State Exam Score (MMSE) < 24 or reported diagnosis of dementia or Alzheimer’s disease (AD) at the follow-up among people with MMSE ≥ 24 and no diagnosis of dementia or AD at baseline. Results There was a significant association between olfactory impairment at baseline and the 5-year incidence of cognitive impairment (Odds Ratio (O.R.) = 6.62, 95% Confidence Interval (C.I.) = 4.36, 10.05). The association remained significant after adjusting for possible confounders (O.R. = 3.72, 95% C.I. = 2.31, 5.99). The Positive Predictive Value of the SDOIT was 15.9%, the Negative Predictive Value was 97.2% and the sensitivity and specificity were 55.1% and 84.4%, respectively, for the 5-year incidence of cognitive impairment. Conclusion Olfactory impairment at baseline was strongly associated with the 5-year incidence of cognitive impairment as measured by the MMSE. Odor identification testing may be useful in high risk settings, but not in the general population, to identify patients at risk for cognitive decline. PMID:18662205

    Acrodynia is a reaction that occurs in children who have been exposed to mercury. Mercury toxicity has systemic manifestations as well as cutaneous manifestations, which can appear similar to those found in a number of other diseases. We present a case of acrodynia caused by mercury exposure in a previously healthy 5-year-old girl who developed hypertension, palmoplantar pruritus, and a papulovesicular eruption. PMID:27136627

  17. Equatorial Annual Oscillation with QBO-driven 5-year Modulation in NCEP Data

    An analysis is presented of the zonal wind and temperature variations supplied by the National Center for Environmental Prediction (NCEP), which have been assimilated in the Reanalysis and the Climate Prediction Center (CCP) data sets. The derived zonal-mean variations are employed. Stimulated by modeling studies, the data are separated into the hemispherically symmetric and anti-symmetric components, and spectral analysis is applied to study the annual 12-month oscillation and Quasi-biennial Oscillation (QBO). For data samples that cover as much as 40 years, the results reveal a pronounced 5-year modulation of the symmetric AO in the lower stratosphere, which is confined to equatorial latitudes. This modulation is also inferred for the temperature variations but extends to high latitudes, qualitatively consistent with published model results. A comparison between different data samples indicates that the signature of the 5-year oscillation is larger when the QBO of 30 months is more pronounced. Thus there is circumstantial evidence that this periodicity of the QBO is involved in generating the oscillation. The spectral analysis shows that there is a weak anti-symmetric 5-year oscillation in the zonal winds, which could interact with the large antisymmetric A0 to produce the modulation of the symmetric AO as was shown in earlier modeling studies. According to these studies, the 30-month QBO tends to be synchronized by the equatorial Semi-annual Oscillation (SAO), and this would explain why the inferred 5-year modulation is observed to persist and is phase locked over several cycles.

    Slow slip events (SSEs) in Cascadia occur at ~30-50 km depth, every 10-19 months, and typically involve slip of a few cm, producing surface displacements on the order of a few mm up to ~1cm. Are there smaller SSE signals that are currently not recognized geodetically? What is the spatial, temporal and size distribution of SSEs, and how are SSE related to tremor? We address these questions with a catalogue of all detectable SSEs spanning the last 6.5 years using a new methodology based on Vertical Derivatives of Horizontal Stress (VDoHS) rates obtained from cGPS times series. VDoHS rates, calculated by solving the force balance equations at the Earth's surface, represent the most inclusive and spatially compact surface expressions of subsurface deformation sources: VDoHS rate vectors are tightly localized above the sources and point in the direction of push or pull. We compare our results with those from the Network Inversion Filter (NIF) for selected events. We identify and characterize a spectrum of SSEs, including events with moment release at least two orders of magnitudes smaller than has been previously identified with GPS data. We catalogue events timing, interface slip distribution and moment release, and compare our results with existing tremor catalogues. VDoHS rates also reveal the boundaries between the locked and unlocked portions of the megathrust, and we can track how this varies throughout the SSE cycle. Above the locked interface, the pull of the subducted plate generates shear tractions in the overlying plate in the direction of subduction, while above the creeping section shear tractions are in the opposite direction, which is reflected in the VDoHS rates. We show that sections of the Cascadia megathrust unlock prior to some SSEs and lock thereafter, with the locked zone propagating downdip and eastward after the SSEs over weeks to months. The catalogue and movies of events will be available at http://www.ig.utexas.edu/people/staff/lada/SSEs.

    Background Human rotaviruses are the most important agents for severe dehydrating diarrhea in children below 5 years old. Rotaviruses (RV) is a serious public health problem in developing and developed countries. Objectives The aim of this study was to determine the prevalence of rotavirus infection and their genotypes in children younger than 5 years of age with acute diarrhea in Ahvaz, Iran. Materials and Methods For this study, 200 stool samples from children below 5 years of age with acute diarrhea were collected between October 2011 and March 2012. Initially all stool samples were tested for rotavirus antigen by ELISA, and positive samples were confirmed by RT-PCR targeting the VP6 rotavirus gene. Determination of rotavirus genotypes was carried out by performing RT-PCR for G and P types. Altogether, 15 samples were sequenced. Results Out of 200 stool samples, 100 (50%) had rotavirus antigen detected by ELISA and 73 (36.5%) were found positive by RT-PCR. Of the rotavirus strains identified, only 63 (86.3%) were positive for both VP7 and VP4 while 10 (13.7%) strains were found nontypeable. Rotavirus infection accounts for 36.5% of gastroenteritis cases in samples from symptomatic children. The most prevalent rotavirus genotypes were G1P [8] (80%) followed by G2P [4] (20%). Conclusions Our results suggest that group A rotavirus is a major pathogene of acute diarrhea in Ahvaz city. The genotypes circulating are similar with those of other countries. PMID:27307959

    Cryopreservation of ovarian tissue is one way of preserving fertility in young women with a malignant disease or other disorders that require gonadotoxic treatment. The purpose of the study was to explore how many women remained interested in continued cryostorage of their ovarian tissue beyond an initial 5-year period. Between 1999 and 2006, a total of 201 girls and young women had one ovary cryopreserved for fertility preservation in Denmark. One hundred of these met our inclusion criteria, which included a follow-up period of at least 5 years, and were mailed a questionnaire. The response rate was 95%. Sixteen of the patients (17%) stated that they wanted disposal of their tissue; the main reason was completion of family (63%). The mean age of those requesting disposal was 36.6 years, whereas those still wanting their tissue stored were significantly younger, with a mean age of 33.0 years (P < 0.008). In conclusion, most women with ovarian tissue cryobanked requested continued cryostorage after an initial period of at least 5 years. The main reason for requesting disposal was successful completion of a family. PMID:25129692

    Study Objectives: This study involves a replication and extension of a previous one reported by Hurwitz et al (1991) on the treatment of certain parasomnias with hypnosis. Methods: Thirty-six patients (17 females), mean age 32.7 years (range 6–71). Four were children aged 6 to 16. All had chronic, “functionally autonomous” (self-sustaining) parasomnias. All underwent 1 or 2 hypnotherapy sessions and were then followed by questionnaire for 5 years. Results: Of the 36 patients, 45.4% were symptom-free or at least much improved at the 1-month follow-up, 42.2% at the 18-month follow-up, and 40.5% at the 5-year follow-up. Conclusions: One or 2 sessions of hypnotherapy might be an efficient first-line therapy for patients with certain types of parasomnias. Citation: Hauri PJ; Silber MH; Boeve BF.

    Post-traumatic endocrine dysfunction is a complication of traumatic brain injury (TBI). However, there is lack of long-term follow-up and large sample size studies. This study included patients suffering from TBI registered in the Health Insurance Database. Endocrine disorders were identified using the ICD codes: 244 (acquired hypothyroidism), 253 (pituitary dysfunction), 255 (disorders of the adrenal glands), 258 (polyglandular dysfunction), and 259 (other endocrine disorders) with at least three outpatient visits within 1 year or one admission diagnosis. Overall, 156,945 insured subjects were included in the final analysis. The 1- and 5-year incidence rates of post-traumatic endocrinopathies were 0.4% and 2%, respectively. The risks of developing a common endocrinopathy (p < 0.001) or pituitary dysfunction (P < 0.001) were significantly higher in patients with a TBI history. Patients with a skull bone fracture had a higher risk of developing pituitary dysfunction at the 1-year follow up (p value < 0.001). At the 5-year follow up, the association between intracranial hemorrhage and pituitary dysfunction (p value: 0.002) was significant. The risk of developing endocrine dysfunction after TBI increased during the entire 5-year follow-up period. Skull bone fracture and intracranial hemorrhage may be associated with short and long-term post-traumatic pituitary dysfunction, respectively. PMID:27608606

    Anemia in children under 5 years of age, defined by the World Health Organization as a hemoglobin concentration < 11 g/dL, is a global public health problem. According to the 2006 Demographic Health Survey, the prevalence of anemia among children under five in Uganda was 72% in 2006. The 2009 Uganda Malaria Indicator Survey was conducted in late 2009 and revealed that over 60% of children less than 5 years of age were anemic and that over half of children tested positive for malaria via a rapid diagnostic test. Children with concomitant malaria infection, and in households without any type of mosquito net were more likely to be anemic, confirming that children under 5 years, are vulnerable to both the threat of malaria and anemia and the beneficial effect of malaria prevention tools. However, prevention and treatment of other factors associated with the etiology of anemia (e.g., iron deficiency) are likely necessary to combat the toll of anemia in Uganda. PMID:26055748

    Treatments for immune thrombocytopenic purpura (ITP) providing durable platelet responses without continued dosing are limited. Whereas complete responses (CRs) to B-cell depletion in ITP usually last for 1 year in adults, partial responses (PRs) are less durable. Comparable data do not exist for children and 5-year outcomes are unavailable. Patients with ITP treated with rituximab who achieved CRs and PRs (platelets > 150 × 109/L or 50-150 × 109/L, respectively) were selected to be assessed for duration of their response; 72 adults whose response lasted at least 1 year and 66 children with response of any duration were included. Patients had baseline platelet counts < 30 × 109/L; 95% had ITP of > 6 months in duration. Adults and children each had initial overall response rates of 57% and similar 5-year estimates of persisting response (21% and 26%, respectively). Children did not relapse after 2 years from initial treatment whereas adults did. Initial CR and prolonged B-cell depletion predicted sustained responses whereas prior splenectomy, age, sex, and duration of ITP did not. No novel or substantial long-term clinical toxicity was observed. In summary, 21% to 26% of adults and children with chronic ITP treated with standard-dose rituximab maintained a treatment-free response for at least 5 years without major toxicity. These results can inform clinical decision-making. PMID:22566601

    Children are not small adults. The differences between children of different age groups and adults are not merely due to body weight, but also due to physiological and biochemical differences resulting in different rates of drug metabolism or renal clearance. Glucuronidation is an important pathway of drug metabolism. Therefore, the objective of this study is to evaluate the predictive performance of several allometric exponents in children of ≤5 years for the total clearance of drugs which are mainly metabolized by glucuronidation. Four exponents (0.75, 1.0, 1.2, or 1.4) on the body weights and an allometric model developed from adults were evaluated. The four exponents and the allometric model were examined to determine the suitability of the method(s) to predict the clearances of drugs which are glucuronidated in children ≤5 years of age. Based on the analysis of ten drugs, it was noted that the combination of two allometric exponents 1.2 (for children ≤3 months) and 1.0 (for children ≥3 months ≤5 years) can be used to predict mean clearances of drugs which are mainly metabolized by glucuronidation. The suggested approach may be used to estimate a first-in-pediatric dose to initiate a pediatric clinical trial. PMID:24519316

    We reviewed evidence on total wrist replacement from the last 5 years. Eight articles met a minimum set standard. The results of 405 prostheses were available, including seven different manufacturers. The mean follow up was 2.3-7.3 years with an average age of 52-63. Rheumatoid arthritis was the indication in 42% of patients. Motec demonstrated the best post-operative DASH scores. Only Maestro achieved a defined functional range of motion post-operatively. Universal 2 displayed the highest survival rates (100% at 3-5 years), while Elos had the lowest (57% at 5 years). Biaxial had the highest complication rates (68.7%), while Remotion had the lowest (11%). Wrist arthroplasty preserves some range of motion. Functional scores improved and were maintained over the mid- to long-term. Complication rates were higher than wrist fusion, with reports of radiological loosening and osteolysis.

    Prospective studies and intervention evaluations that examine change over time assume that measurement tools measure the same construct at each occasion. In the area of parent-child feeding practices, longitudinal measurement properties of the questionnaires used are rarely verified. To ascertain that measured change in feeding practices reflects true change rather than change in the assessment, structure, or conceptualisation of the constructs over time, this study examined longitudinal measurement invariance of the Feeding Practices and Structure Questionnaire (FPSQ) subscales (9 constructs; 40 items) across 3 time points. Mothers participating in the NOURISH trial reported their feeding practices when children were aged 2, 3.7, and 5 years (N = 404). Confirmatory Factor Analysis (CFA) within a structural equation modelling framework was used. Comparisons of initial cross-sectional models followed by longitudinal modelling of subscales, resulted in the removal of 12 items, including two redundant or poorly performing subscales. The resulting 28-item FPSQ-28 comprised 7 multi-item subscales: Reward for Behaviour, Reward for Eating, Persuasive Feeding, Overt Restriction, Covert Restriction, Structured Meal Setting and Structured Meal Timing. All subscales showed good fit over 3 time points and each displayed at least partial scalar (thresholds equal) longitudinal measurement invariance. We recommend the use of a separate single item indicator to assess the family meal setting. This is the first study to examine longitudinal measurement invariance in a feeding practices questionnaire. Invariance was established, indicating that the subscales of the shortened FPSQ-28 can be used with mothers to validly assess change in 7 feeding constructs in samples of children aged 2-5 years of age.

    Sexual dysfunction is common after surgery for prostate cancer. The aetiology of changes in sexual potency after radical prostatectomy is probably multifactorial, including neurogenic, vascular and psychosexual factors. A prospective study was designed to investigate haemodynamic and psychosexual changes before and after radical retropubic prostatectomy (RRP) for organ-confined prostate cancer. Penile haemodynamic evaluation and an assessment of sexual excitement were performed preoperatively and 3 months after RRP by colour Doppler ultrasonography (CDU) with visual erotic stimulation combined with a single intracavernous injection of a mixture of papaverine/phentolamine. Questionnaires on sexual function [International Index of Erectile Function (IIEF)], general health and quality of life were sent to the patients preoperative, 3 months and 5 years after operation. Forty-eight men participated in the study. Mean age was 62.6 years (range 55-69). CDU did not show any significant reduction in mean peak systolic flow velocity and mean resistance index. From the men who preoperatively had normal arterial inflow 18% developed arteriogenic insufficiency. Some form of veno-occlusive insufficiency and low resistance indices were already present in the majority of normal potent men preoperatively. Surgical technique did not influence penile arterial blood flow after the operation. Three months and 5 years postoperatively, there was a highly significant reduction in erectile function, intercourse satisfaction, overall satisfaction, orgasmic function and sexual desire. However, with respect to the outcome at 3 months there was a significant improvement of orgasmic function 5 years after operation, especially after a bilateral nerve sparing procedure. Erections sufficient for vaginal penetration (questions 3 and 4 of the IIEF, score >or=8) improved from 2% to 11% 3 months and 5 years after RRP respectively. Total IIEF score was significantly better after a bilateral nerve

  12. Resveratrol Fails to Extend Life Span in the Mosquito Anopheles stephensi.

    Resveratrol, a plant polyphenol present in grape skins, has been theorized to account for the "French Paradox" by explaining how red wine may decrease the health risks associated with unhealthy diets. Resveratrol has been reported to extend life span in several different species. Other studies, however, have failed to find a resveratrol-induced life span effect. A recent meta-study analyzing previously published survival data concluded that, although resveratrol reliably and reproducibly extends life span in some species, its life span effects show diminished reliability in other organisms. The data are mixed, and it remains unclear how evolutionarily conserved resveratrol's effects on life span are. To gain further insight into this controversy, we studied the effects of various concentrations (200 μM, 100 μM, 50 μM, or 0 μM) of orally fed resveratrol on the life span of the mosquito Anopheles stephensi, an important vector of human malaria, under two different feeding treatments--sugar-fed only or sugar-fed with intermittent blood meals. Each treatment was repeated three times and both survivorship and mortality rates were analyzed for each replicate. For the majority of experiments, resveratrol failed to mediate a statistically significant effect on life span. Although there was one instance where resveratrol significantly increased life span, there were five other instances where resveratrol significantly decreased life span. We conclude from these data that, under normal conditions, resveratrol does not extend life span in A. stephensi. PMID:25848933

    Objectives: We previously reported clinical improvement and pain relief following arthroscopic management of glenohumeral osteoarthritis (GHOA) at 2 years. The purpose of this study was to determine 5 year survivorship for the comprehensive arthroscopic management (CAM) procedure for the treatment of GHOA. Methods: This study had prior IRB approval. The CAM procedure was performed on a consecutive series of 42 young patients (44 shoulders) with GHOA who otherwise met criteria for shoulder arthroplasty but instead opted for joint preservation. The procedure included glenohumeral chondroplasty, capsular release, and synovectomy, humeral osteoplasty, axillary nerve neurolysis, subacromial decompression, loose body removal, microfracture and biceps tenodesis. Only patients who were a minimum of 5 years out from surgery were included in the study. Patients completed a subjective questionnaire, and further surgical intervention of the index shoulder was noted for survivorship analysis. Failure was defined as progression to TSA. Kaplan Meier survivorship analysis was performed. Results: Forty-two patients (with 44 shoulders) underwent a CAM procedure between 1/2006-12/2009 and were included. All patients were self-described recreational athletes. Seven patients were former collegiate or professional athletes. Mean follow-up was 5.9 years (range, 5 years to 8.1 years). Mean age at surgery was 52 (range 27- 68) years old in 13 women and 29 men. Eleven shoulders (26%) failed and progressed to TSA at a mean of 2.9 years (1.0-5.4 years). Shoulder status (progression to TSA or not) at minimum 5 years (range 5.3 - 9.4 years) was known for 95% (42/44). One patient progressed to another surgery for stiffness at a mean of 5.6 months and another patient underwent a revision CAM procedure at 7.9 years. From this cohort, Kaplan Meier survivorship was 92% at 1 year, 85.7% at 3 years, and 75.3% survivorship at 5 years. Conclusion: The long term durability of arthroscopic management for

    Since 2009, the Large Hadron Collider (LHC) is in operation at CERN. The LHC superconducting magnets distributed over eight sectors of 3.3-km long are cooled at 1.9 K in pressurized superfluid helium. The nominal operating temperature of 1.9 K is produced by eight 1.8-K refrigeration units based on centrifugal cold compressors (3 or 4 stages depending to the vendor) combined with warm volumetric screw compressors with sub-atmospheric suction. After about 5 years of continuous operation, we will present the results concerning the availability for the final user of these refrigeration units and the impact of the design choice on the recovery time after a system trip. We will also present the individual results for each rotating machinery in terms of failure origin and of Mean Time between Failure (MTBF), as well as the consolidations and upgrades applied to these refrigeration units.

  15. Examining implicit metacognition in 3.5-year-old children: an eye-tracking and pupillometric study

    2013-01-01

    The current study examined early signs of implicit metacognitive monitoring in 3.5-year-old children. During a learning phase children had to learn paired associates. In the test phase, children performed a recognition task and choose the correct associate for a given target among four possible answers. Subsequently, children's explicit confidence judgments (CJs) and their fixation time allocation at the confidence scale were assessed. Analyses showed that explicit CJs did not differ for remembered compared to non-remembered items. In contrast, children's fixation patterns on the confidence scale were affected by the correctness of their memory, as children looked longer to high confidence ratings when they correctly remembered the associated item. Moreover, analyses of pupil size revealed pupil dilations for correctly remembered, but not incorrectly remembered items. The results converge with recent behavioral findings that reported evidence for implicit metacognitive memory monitoring processes in 3.5-year-old children. The study suggests that implicit metacognitive abilities might precede the development of explicit metacognitive knowledge. PMID:23526709

    A longitudinal cohort study of 100 people with traumatic spinal cord injury (SCI) was performed to determine the prevalence and severity of different types of pain (musculoskeletal, visceral, neuropathic at-level, neuropathic below-level) at 5 years following SCI. Prospective data on the characteristics of pain up to 6 months following injury had been collected previously and allowed comparisons between the presence of pain at different time points. In addition, we sought to determine the relationship between the presence of pain and physical factors related to the injury such as level of lesion, completeness and clinical SCI syndrome. We also obtained information regarding mood, global self-rated health and the impact of pain on function. Of the 100 subjects in the original cohort, 73 were available for follow up. When all types of pain were included, 59 of the 73 subjects (81%) reported the presence of pain. Musculoskeletal pain was the most common type of pain experienced and was present in 43 subjects (59%), at-level neuropathic pain was present in 30 subjects (41%), below-level neuropathic pain was present in 25 subjects (34%) and visceral pain was present in four subjects (5%). Overall, 58% reported their pain as severe or excruciating and those with visceral pain were most likely to rate their pain in these categories. There was no relationship between the presence of pain overall and level or completeness of lesion, or type of injury. However, tetraplegics were more likely to report below-level neuropathic pain. This study prospectively demonstrates the differing time courses of different types of pain over the first 5 years following SCI. There was a strong correlation between the presence of both types of neuropathic pain at 5 years and earlier time points but both visceral pain and musculoskeletal pain demonstrated a poor correlation between time points. Chronic visceral pain occurs in a small percentage of patients and does not correlate with the

    Osteoarthrosis is a disease that affects the temporomandibular joint (TMJ). This case report chronicles the diagnosis and treatment of a patient for whom this pathological condition was accompanied by a rupture of the articular disc. The patient presented with loud sounds in the left TMJ and an irregular mandibular occlusal plane due to condylar intrusion in the glenoid fossa on the ipsilateral side. A noninvasive treatment was selected. A 4-month follow-up revealed remission of the articular sounds, and tissue regeneration was noted. These improvements remained visible at 5-year follow-up.

    We performed a cross-sectional, community-based survey, supplemented by interviews with community leaders in Chiapas, Mexico, to examine the prevalence and predictors of child malnutrition in regions affected by the Zapatista conflict. The prevalence rates of stunting, wasting, and underweight were 54.1%, 2.9%, and 20.3%, respectively, in 2666 children aged younger than 5 years. Stunting was associated with indigenous ethnicity, poverty, region of residence, and intracommunity division. The results indicate that malnutrition is a serious public health problem in the studied regions. PMID:17194868

    Infantile fibrosarcoma of head and neck is rare and the presence of this tumor in ethmoid sinus is even more uncommon. To the best of our knowledge, <5 cases have been reported in the last 20 years in the English literature, so far, only one of which has been infantile type in a 15 months old girl. In this case report, we will explain our experience with a rare case of infantile fibrosarcoma originating from ethmoid sinus in a 5-year-old boy who presented with dyspnea and epistaxis. After biopsy, it was diagnosed as fibrosarcoma of sinus origin. PMID:26604519

    Objective To describe important sequelae occurring among a cohort of children aged 5 years who had had meningitis during the first year of life and who had been identified by a prospective national study of meningitis in infancy in England and Wales between 1985 and 1987. Design Follow up questionnaires asking about the children's health and development were sent to general practitioners and parents of the children and to parents of matched controls. The organism that caused the infection and age at infection were also recorded. Setting England and Wales. Participants General practitioners and parents of children who had had meningitis before the age of 1 year and of matched controls. Main outcome measures The prevalence of health and developmental problems and overall disability among children who had had meningitis compared with controls. Results Altogether, 1584 of 1717 (92.2%) children who had had meningitis and 1391 of 1485 (93.6%) controls were successfully followed up. Among children who survived to age 5 years 247 of 1584 (15.6%) had a disability; there was a 10-fold increase in the risk of severe or moderate disability at 5 years of age among children who had had meningitis (relative risk 10.3, 95% confidence interval 6.7 to 16.0, P<0.001). There was considerable variation in the rates of severe or moderate disability in children infected with different organisms. Conclusion The long term consequences of having meningitis during the first year of life are significant: 32 of 1717 (1.8%) children died within five years. Not only did almost a fifth of children with meningitis have a permanent, severe or moderately severe disability, but subtle deficits were also more prevalent. What is already known on this topicMeningitis in infancy is associated with important long term consequencesThere is considerable variation in outcome depending on which organism caused the infectionWhat this study addsThis follow up study of 1717 children who had meningitis in infancy

    Anesthesia-related central anticholinergic syndrome (CAS) is most commonly associated with administration of atropine or scopolamine, whereas glycopyrrolate is an extremely rare cause of CAS. Here, we report a case of CAS in a 5-year-old boy admitted to the intensive care unit. Immediately after the administration of glycopyrrolate, he became agitated and developed apnea, hypertension, tachycardia, and anuria. Although the present case describes a rare cause of CAS, it is an important reminder of an iatrogenic condition that is presumably underdiagnosed in the operating theater as well as the intensive care unit.

    Renal leiomyomas are exceptionally rare benign tumours of the kidney. Although the renal leiomyomas usually do not metastasize, the differential diagnosis between renal leiomyomas and malign lesions (leiomyosarcoma or renal cell carcinoma) cannot be done by radiological examinations, but is possible by histological examination. Surgery is the preferred treatment. After surgery, the prognosis is excellent without recurrence. Although uterine leiomyomas can be multicentric, renal leiomyomas have been single lesions. We report an incidentally detected case of bilateral renal leiomyoma in a 50-year-old woman with a 5-year follow-up. We also review the literature and discuss clinical, radiological and histological features of renal leiomyomas. PMID:26664510

    Meckel's diverticulum is understood to be the commonest congenital malformation within the gastrointestinal tract with a prevalence of 2%, as found on autopsy studies. Although many cases are asymptomatic, complications can occur including haemorrhage, diverticulitis, chronic ulceration and intestinal obstruction. Intussusception is also a complication, but extremely rare. We present a rare case of Meckel's diverticulum causing intussusception, which was surgically resolved, in a 5-year-old girl. Our aim through this case report is to generate greater awareness of this complication and to provide some potential guidance towards its treatment. PMID:25540213

A special installation was employed in the tests utilizing a half-span airfoil mounted vertically above a reflection plane. The airfoil has a constant chord center section and rounded tips and is tapered in thickness from 18 percent c at the root to 9 percent c at the tip. The aerodynamic characteristics, given by the usual dimension less coefficients, are presented graphically as functions of flap span and angle of attack as well as by semispan load diagrams. The results indicate, in general, that only a relatively small increase in the normal-force coefficient is to be expected by extending the flap span of an airfoil-flap combination, similar to the one tested, beyond 70 percent of the wing span.

    We study budget constrained optimal network upgrading problems. Such problems aim at finding optimal strategies for improving a network under some cost measure subject to certain budget constraints. A general problem in this setting is the following. We are given an edge weighted graph G = (V, E) where nodes represent processors and edges represent bidirectional communication links. The processor at a node v {element_of} V can be upgraded at a cost of c(v). Such an upgrade reduces the delay of each link emanating from v. The goal is to find a minimum cost set of nodes to be upgraded so that the resulting network has the best performance with respect to some measure. We consider the problem under two measures, namely, the weight of a minimum spanning tree and the bottleneck weight of a minimum bottleneck spanning tree. We present approximation and hardness results for the problem. Our results are tight to within constant factors. We also show that these approximation algorithms can be used to construct good approximation algorithms for the dual versions of the problems where there is a budget constraint on the upgrading cost and the objectives are minimum weight spanning tree and minimum bottleneck weight spanning tree respectively.

    1. Clonal populations face a trade-off between sexual recruitment and vegetative growth and, once established, may undergo continuous declines in genotypic diversity if their sexual recruits make poor competitors. The geological history of delta formation in the Lower Mississippi River Valley was used to age eight 5. alterniflora marshes for use in a space-for-time substitution ranging over 1500 years, in order to determine the long-term effects of clonal growth on genotypic diversity in natural populations. 2. We also predicted that highly heterozygous clones are competitively superior, leading to an increase in the overall level of genetic diversity as a marsh ages and/or to an increasingly positive relationship between clone size and individual heterozygosity, and that the clumping of ramets within clones will occur over increasingly large distances as populations age, while the clumping of genetically related clones will become less pronounced as intraclonal competition begins to obscure the initial effects of localized seedling recruitment. 3. Using molecular markers to differentiate clones, we documented a decline in clonal richness at the rate of approximately 1% 100 years -1 that was accompanied for the first 300-500 years by an increase in the distance over which clumping of ramets within genets occurred. Older populations, in the 500-1500-year range, showed evidence of clone fragmentation. 4. The spatial clustering of kin was observed for only two marshes, and exhibited no clear relationship with marsh age. 5. Whereas the overall level of genetic diversity was consistent among marshes and showed no clear relationship with marsh age, the relationship between heterozygosity and individual clone size became increasingly pronounced within older marshes. 6. Our results suggest that under natural conditions S. alterniflora marshes will rarely reach ages sufficient for the loss of all clonal diversity, or for the effects of inbreeding and drift to pose a

    This study evaluated the incidence, serotype distribution, and antimicrobial susceptibility of invasive pneumococcal disease (IPD) in Saudi Arabian children. This multicenter, prospective, clinical surveillance study included children under 5years of age, residents of one of the seven study health areas, who were brought to a study hospital with suspicion of IPD. Bacterial isolates from sterile site samples, collected less than 24h after hospital visit/admission, were identified, serotyped, and tested for antibiotic susceptibility. Between June 2007 and January 2009, 631 episodes of suspected IPD were recorded, and 623 were included in the analysis. One child (0.2%) had previously received one dose of a pneumococcal vaccine. Forty-seven episodes were positive for Streptococcus pneumoniae and three for Haemophilus influenzae. The incidence of confirmed IPD cases was estimated to be 2.5-21.6 per 100,000 children (<5years). Among the 46 S. pneumoniae isolates serotyped and tested for antibiotic susceptibility, the most common serotypes were 5 and 23F (20% each), 6B (17%), and 1 and 14 (11% each). Sixty-three percent of isolates were multidrug-resistant. Vaccination of Saudi Arabian children with expanded-coverage conjugate pneumococcal vaccines containing serotypes 1 and 5 could have a substantial impact to prevent IPD in this population.

    The clinical periodontal status of 44 insulin-dependent diabetic children and adolescents and 20 healthy control subjects was compared for a period of approximately 5 years. Fasting blood glucose, fructosamine, and glycosylated hemoglobin (HbA1) values were determined at baseline and 5 years later. The differences in the clinical and laboratory parameters were compared during the study period. The differences between the two groups were also evaluated. The only statistically significant difference observed in the diabetic group was clinical attachment loss (CAL). The CAL was statistically significantly higher in the diabetic group compared to the controls, and a statistically significantly higher in the diabetic group compared to the controls, and a statistically significant positive correlation was observed between the duration of diabetes and CAL. Fructosamine was also correlated with the gingival index in the diabetic group while there was no correlation in the controls. It may be concluded that diabetes modifies the clinical status of the periodontal tissues and increases clinical attachment loss. PMID:9058330

    Purpose To determine the rate and risk factors of diabetic retinopathy (DR) onset and regression in Chinese type 2 diabetes mellitus patients. Methods This is a 5-year community-based prospective study. The demographic information, systemic examination results and ophthalmological test results of each participant were collected. The study outcomes were DR incidence, defined as the onset of DR in at least one eye, and DR regression, defined as full regression from existing DR to no retinopathy without invasive treatments. The associations between each potential risk factor and the outcomes were studied. Results In total, 778 participants were enrolled. There were 322 patients without DR at baseline, of which 151 participants developed DR during follow-up (DR incidence rate = 46.89%). Baseline hyperglycemia and high blood pressure were two independent risk factors associated with DR incidence. Among the 456 participants with existing DR at entry, 110 fully recovered after 5 years (DR regression rate = 24.12%). Low baseline glucose and low serum triglyceride were two independent factors associated with DR regression. Conclusions DR incidence occurred more frequently in patients with hyperglycemia and high blood pressure. DR regression occurred mostly in patients with lower glucose and lower serum triglyceride levels among Chinese type 2 diabetes patients. PMID:25402474

    Objectives. To evaluate scholarship, as represented by peer-reviewed journal articles, among US pharmacy practice faculty members; contribute evidence that may better inform benchmarking by academic pharmacy practice departments; and examine factors that may be related to publication rates. Methods. Journal articles published by all pharmacy practice faculty members between January 1, 2006, and December 31, 2010, were identified. College and school publication rates were compared based on public vs. private status, being part of a health science campus, having a graduate program, and having doctor of pharmacy (PharmD) faculty members funded by the National Institutes of Health (NIH). Results. Pharmacy practice faculty members published 6,101 articles during the 5-year study period, and a pharmacy practice faculty member was the primary author on 2,698 of the articles. Pharmacy practice faculty members published an average of 0.51 articles per year. Pharmacy colleges and schools affiliated with health science campuses, at public institutions, with NIH-funded PharmD faculty members, and with graduate programs had significantly higher total publication rates compared with those that did not have these characteristics (p<0.006). Conclusion. Pharmacy practice faculty members contributed nearly 6,000 unique publications over the 5-year period studied. However, this reflects a rate of less than 1 publication per faculty member per year, suggesting that a limited number of faculty members produced the majority of publications. PMID:23049099

    OBJECTIVE To analyze vaccination coverage and factors associated with a complete immunization scheme in children < 5 years old. METHODS This cross-sectional household census survey evaluated 1,209 children < 5 years old living in Bom Jesus, Angola, in 2010. Data were obtained from interviews, questionnaires, child immunization histories, and maternal health histories. The statistical analysis used generalized linear models, in which the dependent variable followed a binary distribution (vaccinated, unvaccinated) and the association function was logarithmic and had the children’s individual, familial, and socioeconomic factors as independent variables. RESULTS Vaccination coverage was 37.0%, higher in children < 1 year (55.0%) and heterogeneous across neighborhoods; 52.0% of children of both sexes had no immunization records. The prevalence rate of vaccination significantly varied according to child age, mother’s level of education, family size, ownership of household appliances, and destination of domestic waste. CONCLUSIONS Vulnerable groups with vaccination coverage below recommended levels continue to be present. Some factors indicate inequalities that represent barriers to full immunization, indicating the need to implement more equitable policies. The knowledge of these factors contributes to planning immunization promotion measures that focus on the most vulnerable groups. PMID:26039393

    The study assessed the 5-year follow-up outcome and possible prognostic factors of migraine subtypes with onset in childhood or adolescence. A total of 343 patients meeting the International Classification of Headache Disorders (ICHD)-II criteria for migraine without aura (MO), migraine with aura (MA), or both MO+MA (ie, 1.1, 1.2) were contacted by phone and underwent structured follow-up headache interviews. Of the original sample patients, 22.7% were headache-free at follow-up, 14.1% had a transformed headache diagnosis (tension-type headache: 8.2%, chronic daily headache: 5.8%), and 63.3% still had migraine fulfilling the criteria for ICHD-II 1.1. or 1.2, but those who were still migraineurs at follow-up were older at baseline (respectively 12.93, 9.99, and 11.02 years for MO, MA and MO+MA, P = .0005). The probability of having the same migraine subtype diagnosis at baseline and at 5-year follow-up was 55.2%, 95.1%, and 31.1% for ICHD-II 1.1, 1.2, and both 1.1 and 1.2, respectively. PMID:27071466

    Summary Many children younger than 5 years in developing countries are exposed to multiple risks, including poverty, malnutrition, poor health, and unstimulating home environments, which detrimentally affect their cognitive, motor, and social-emotional development. There are few national statistics on the development of young children in developing countries. We therefore identified two factors with available worldwide data—the prevalence of early childhood stunting and the number of people living in absolute poverty—to use as indicators of poor development. We show that both indicators are closely associated with poor cognitive and educational performance in children and use them to estimate that over 200 million children under 5 years are not fulfilling their developmental potential. Most of these children live in south Asia and sub-Saharan Africa. These disadvantaged children are likely to do poorly in school and subsequently have low incomes, high fertility, and provide poor care for their children, thus contributing to the intergenerational transmission of poverty.

    The term mixed emotions refers to the presence of two opposite-valence emotions toward a single target. Identifying when children begin to report experiencing and understanding mixed emotions is critical in identifying how skills such as adaptive functioning, coping strategies, environmental understanding, and socioemotional competence emerge. Prior research has shown that children as young as 5 years old can understand and experience mixed emotion, but perhaps appropriately sensitive methodologies can reveal these abilities in younger children. The present study evaluated 57 children between 3 and 5 years old for mixed emotion experience and understanding using an animated video clip in which a character experiences a mixed emotional episode. Ordinal logistic regression was utilized to examine the relation of gender, attention, and understanding of content to experience and understanding of mixed emotion. While only 12% of children reported experiencing mixed emotion while watching the clip, 49% of children-some as young as 3 years old-were able to recognize the mixed emotional experience of the character. Thus, mixed emotion understanding emerges earlier than previously identified and the expression of understanding may develop independently of the ability to report mixed emotion experience. These findings are discussed in relation to cognitive and developmental considerations. PMID:25695201

    The aim of this 5-year longitudinal cohort study was to assess the prevalence, severity, and trends in caries increment and impact of the School Dental Incremental Care Programme (SDICP). Data were gathered from school dental records as part of the SDICP. A sample of 1830 children were included and checked for caries experience annually using World Health Organization criteria. In total, 95.4% of the children were caries free in 2004, and caries experience declined to 70.5% in 2009 with an average of 4.9% annually. At baseline, the mean DMFT (confidence interval [CI]) was 0.06 (0.05-0.08) and increased to 0.58 (0.53-0.63) in 2009. Children with active caries were 4.4% in 2004, and figures rose to 9.6% in 2009. The FT component increased most rapidly during these 5 years from 0.2% to 25.1%. Overall caries prevalence and increment was low in this study. Proportions of FT component were higher as compared with DT component with low rate of extractions during the latter years of the study. PMID:22218936

    The incidence of fatal injuries in children has been reported to be highest among children aged 1 to 4 years. Major causes of head injury include road traffic accidents, falls, and intentional or inflicted injury (such as nonaccidental injury syndrome). This study reviewed the profile of children (under 5 years of age) who had been admitted to a large urban medicolegal mortuary (in Pretoria, the capital city of South Africa), after having suffered fatal head injuries. This study was conducted over a 5-year period (from January 2004 through December 2008), and a total of 107 cases were identified for inclusion. These cases constituted nearly a fifth of admissions in this age group. The male-to-female ratio was 56%:44%, and the peak age of injury was less than 1 year. Most head injuries were sustained in road traffic accidents (70%) followed by falls (10%) and other types of blunt force injuries (9%). Only 1 case of nonaccidental injury syndrome (child abuse) was found. The great majority of deaths were deemed to have been accidental in nature (91%) with 6 (6%) homicides. Urgent review pertaining to the use of child restraint devices and the safety of pedestrians is required, and the institution of childhood injury registers could aid in reducing childhood fatalities in South Africa.

    In adults and older children, evidence consistent with relative separation between selective and sustained attention, superimposed upon generally positive inter-test correlations, has been reported. Here we examine whether this pattern is detectable in 5-year-old children from the healthy population. A new test battery (TEA-ChJ) was adapted from measures previously used with adults and older children and administered to 172 5-year-olds. Test-retest reliability was assessed in 60 children. Ninety-eight percent of the children managed to complete all measures. Discrimination of visual and auditory stimuli were good. In a factor analysis, the two TEA-ChJ selective attention tasks (one visual, one auditory) loaded onto a common factor and diverged from the two sustained attention tasks (one auditory, one motor), which shared a common loading on the second factor. This pattern, which suggests that the tests are indeed sensitive to underlying attentional capacities, was supported by the relationships between the TEA-ChJ factors and Test of Everyday Attention for Children subtests in the older children in the sample. It is possible to gain convincing performance-based estimates of attention at the age of 5 with the results reflecting a similar factor structure to that obtained in older children and adults. The results are discussed in light of contemporary models of attention function. Given the potential advantages of early intervention for attention difficulties, the findings are of clinical as well as theoretical interest. PMID:24376591

    Purpose: Conformal and intensity modulated radiation therapies have the potential to preserve cognitive outcomes in children with ependymoma; however, functional behavior remains uninvestigated. This longitudinal investigation prospectively examined intelligence quotient (IQ) and adaptive functioning during the first 5 years after irradiation in children diagnosed with ependymoma. Methods and Materials: The study cohort consisted of 123 children with intracranial ependymoma. Mean age at irradiation was 4.60 years (95% confidence interval [CI], 3.85-5.35). Serial neurocognitive evaluations, including an age-appropriate IQ measure and the Vineland Adaptive Behavior Scales (VABS), were completed before irradiation, 6 months after treatment, and annually for 5 years. A total of 579 neurocognitive evaluations were included in these analyses. Results: Baseline IQ and VABS were below normative means (P<.05), although within the average range. Linear mixed models revealed stable IQ and VABS across the follow-up period, except for the VABS Communication Index, which declined significantly (P=.015). Annual change in IQ (-.04 points) did not correlate with annual change in VABS (-.90 to +.44 points). Clinical factors associated with poorer baseline performance (P<.05) included preirradiation chemotherapy, cerebrospinal fluid shunt placement, number and extent of surgical resections, and younger age at treatment. No clinical factors significantly affected the rate of change in scores. Conclusions: Conformal and intensity modulated radiation therapies provided relative sparing of functional outcomes including IQ and adaptive behaviors, even in very young children. Communication skills remained vulnerable and should be the target of preventive and rehabilitative interventions.

    Background: This study evaluated the efficacy of percutaneous nucleoplasty using coblation technique for the treatment of chronic nonspecific low back pain (LBP), after 5 years of follow-up. Methods: From September 2004 to November 2006, 172 patients underwent percutaneous nucleoplasty for chronic LBP in our department. Forty-one of these patients were followed up for a mean period of 67 months. Nucleoplasty was performed at L3/4 in 1 patient; L4/5 in 25 patients; L5/S1 in 2 patients; L3/4 and L4/5 in 2 patients; L4/5 and L5/S1 in 7 patients; and L3/4, L4/5, and L5/S1 in 4 patients. Patients were assessed preoperatively and at 1 week, 1 year, 3 years, and 5 years postoperatively. Pain was graded using a 10-cm Visual Analogue Scale (VAS) and the percentage reduction in pain score was calculated at each postoperative time point. The Oswestry Disability Index (ODI) was used to assess disability-related to lumbar spine degeneration, and patient satisfaction was assessed using the modified MacNab criteria. Results: There were significant differences among the preoperative, 1-week postoperative, and 3-year postoperative VAS and ODI scores, but not between the 3- and 5-year postoperative scores. There were no significant differences in age, sex, or preoperative symptoms between patients with effective and ineffective treatment, but there were significant differences in the number of levels treated, Pfirrmann grade of intervertebral disc degeneration, and provocative discography findings between these two groups. Excellent or good patient satisfaction was achieved in 87.9% of patients after 1 week, 72.4% after 1 year, 67.7% after 3 years, and 63.4% at the last follow-up. Conclusions: Although previously published short- and medium-term outcomes after percutaneous nucleoplasty appeared to be satisfactory, our long-term follow-up results show a significant decline in patient satisfaction over time. Percutaneous nucleoplasty is a safe and simple technique, with therapeutic

  14. A Delayed and Rather Unusual Presentation of a Bladder Injury after Pelvic Trauma: 5 Years after a Road Traffic Accident

    2014-01-01

    Associated injuries frequently occur in patients who sustain fractures of the pelvis. Specifically, high-energy trauma resulting in pelvic fractures places the bladder and urethra at risk for injury, often resulting in significant complications. Timely identification and management of genitourinary injuries minimize associated morbidity. Prompt injury identification depends upon a systematic evaluation with careful consideration of the mechanism of injury. Physical examination is pertinent as well as analysis of the urine and appropriate diagnostic imaging. Despite such increased vigilance genitourinary injuries get missed and delayed presentations in the order of a few weeks have been well documented. To our knowledge, this is the first report of its kind in the literature showing such a particularly delayed (5 years) and rather unusual presentation of a bladder injury after pelvic trauma.

    Hurler syndrome is a rare autosomal recessive disorder of mucopolysaccharide metabolism. It results from a deficiency in lysosomal enzymes responsible for the breakdown of glycosaminoglycans. Affected individuals may show progressive physical and mental deterioration as glycosaminoglycans are deposited in the organs of the body. Bone marrow transplantation (BMT) is effective in improving some of the clinical manifestations of Hurler syndrome. Death is caused by cardiorespiratory failure and usually occurs before the second decade of life. In this case report, the course of dental development was followed over 5 years, from the primary dentition into the permanent dentition, of a child who was successfully treated with a bone marrow transplant in infancy. The timing of bone marrow therapy has significant and variable effect on the stages of tooth development with implications for the long-term maintenance of the dentition. PMID:20051069

    Objectives The aims of this study are to answer the following questions (1) How does the pain intensity of lumbar and cervical disc surgery patients change within a postoperative time frame of 5 years? (2) Which sociodemographic, medical, work-related, and psychological factors are associated with postoperative pain in lumbar and cervical disc surgery patients? Methods The baseline survey (T0; n = 534) was conducted 3.6 days (SD 2.48) post-surgery in the form of face-to-face interviews. The follow-up interviews were conducted 3 months (T1; n = 486 patients), 9 months (T2; n = 457), 15 months (T3; n = 438), and 5 years (T4; n = 404) post-surgery. Pain intensity was measured on a numeric rating-scale (NRS 0–100). Estimated changes to and influences on postoperative pain by random effects were accounted by regression models. Results Average pain decreased continuously over time in patients with lumbar herniated disc (Wald Chi² = 25.97, p<0.001). In patients with cervical herniated disc a reduction of pain was observed, albeit not significant (Chi² = 7.02, p = 0.135). Two predictors were associated with postoperative pain in lumbar and cervical disc surgery patients: the subjective prognosis of gainful employment (p<0.001) and depression (p<0.001). Conclusion In the majority of disc surgery patients, a long-term reduction of pain was observed. Cervical surgery patients seemed to benefit less from surgery than the lumbar surgery patients. A negative subjective prognosis of gainful employment and stronger depressive symptoms were associated with postoperative pain. The findings may promote multimodal rehabilitation concepts including psychological and work-related support. PMID:27243810

    Abstract Background: As previously reported, the magnetic sphincter augmentation device (MSAD) preserves gastric anatomy and results in less severe side effects than traditional antireflux surgery. The final 5-year results of a pilot study are reported here. Patients and Methods: A prospective, multicenter study evaluated safety and efficacy of the MSAD for 5 years. Prior to MSAD placement, patients had abnormal esophageal acid and symptoms poorly controlled by proton pump inhibitors (PPIs). Patients served as their own control, which allowed comparison between baseline and postoperative measurements to determine individual treatment effect. At 5 years, gastroesophageal reflux disease (GERD)-Health Related Quality of Life (HRQL) questionnaire score, esophageal pH, PPI use, and complications were evaluated. Results: Between February 2007 and October 2008, 44 patients (26 males) had an MSAD implanted by laparoscopy, and 33 patients were followed up at 5 years. Mean total percentage of time with pH <4 was 11.9% at baseline and 4.6% at 5 years (P < .001), with 85% of patients achieving pH normalization or at least a 50% reduction. Mean total GERD-HRQL score improved significantly from 25.7 to 2.9 (P < .001) when comparing baseline and 5 years, and 93.9% of patients had at least a 50% reduction in total score compared with baseline. Complete discontinuation of PPIs was achieved by 87.8% of patients. No complications occurred in the long term, including no device erosions or migrations at any point. Conclusions: Based on long-term reduction in esophageal acid, symptom improvement, and no late complications, this study shows the relative safety and efficacy of magnetic sphincter augmentation for GERD.

    Total knee arthroplasties (TKAs) are reliable procedures for treating end-stage knee osteoarthritis with excellent long-term outcomes. The purpose of this study was to longitudinally evaluate temporal trends of Knee Society Scores (KSS) after TKA and to identify potential demographic and comorbid factors that affect these outcomes. This prospective study evaluated 281 patients (108 men and 173 women) with a mean age of 66 years (range, 39-80 years) who underwent primary TKA (minimum follow-up 5 years). During each follow-up visit, KS objective, function, and total scores were evaluated. The effects of different demographics and comorbidities on outcomes were further analyzed using multivariate regression analysis. Following TKA, peak mean KSS were observed at 1-year follow-up (mean, 92 points), after which there was no significant difference in scores at 5 years compared with 1-year follow-up (mean, 92 points). KS function scores were observed to be unchanged from preoperative levels (mean, 53 points) and at 6 weeks (mean, 56 points). These were significantly higher at 3 months (mean, 78 points) and reached a maximum mean peak at 1 year (mean, 85 points). KS objective scores increased earlier than function scores. The demographic variables and comorbidities that demonstrated a significantly negative impact in KS function scores were increased age, female gender, higher body mass index, and several medical comorbidities including immunological and neurological disease, and neoplasm. Race was the only variable that significantly decreased the KS objective scores. KSS after TKA follow temporal trends with scores initially unchanged from preoperative levels for the objective component, but the scores increased for the functional component. All components demonstrated higher levels compared with preoperative scores by 3 months and peaked at 1-year follow-up. At 5-year follow-up, all mean KSS were unchanged relative to peak scores seen at 1 year. Various patient

    In this paper, we report on a 5-year-old girl who developed a renal stone while following the ketogenic diet to treat refractory seizure disorder. Three months after initiating the ketogenic diet, she developed severe abdominal pain and vomiting. The spot urine calcium-to-creatinine (Ca/Cr) ratio and 24-hour urine evaluation showed hypercalciuria. Computed tomography (CT) imaging revealed a stone in the right ureteropelvic junction, resulting in hydronephrosis of the right kidney. The renal stone disappeared 5 days after conservative treatment; the patien's microscopic hematuria resolved concurrently. In light of this case report, we recommend regularly monitoring the urine Ca/Cr ratio with ultrasonography for further development of renal stones in patients following the ketogenic diet. If these patients exhibit evidence of symptomatic hypercalciuria or cyristalluria, liberalization of fluid restriction and urine alkalization using oral potassium citrate should be considered.

    Over the past 5 years numerous reports have confirmed and replicated the specific brain cooling and thermal window predictions derived from the thermoregulatory theory of yawning, and no study has found evidence contrary to these findings. Here we review the comparative research supporting this model of yawning among homeotherms, while highlighting a recent report showing how the expression of contagious yawning in humans is altered by seasonal climate variation. The fact that yawning is constrained to a thermal window of ambient temperature provides unique and compelling support in favor of this theory. Heretofore, no existing alternative hypothesis of yawning can explain these results, which have important implications for understanding the potential functional role of this behavior, both physiologically and socially, in humans and other animals. In discussion we stress the broader applications of this work in clinical settings, and counter the various criticisms of this theory. PMID:23293583

    1999-01-01

    The Mir Cooperative Solar Array (MCSA) was developed jointly by the United States and Russia to produce 6 kW of power for the Russian space station Mir. Four, multi-orbit test sequences were executed between June 1996 and December 1998 to measure MCSA electrical performance. A dedicated Fortran computer code was developed to analyze the detailed thermal-electrical performance of the MCSA. The computational performance results compared very favorably with the measured flight data in most cases. Minor performance degradation was detected in one current generating section of the MCSA. Yet overall, the flight data indicated the MCSA was meeting and exceeding performance expectations. There was no precipitous performance loss due to contamination or other causes after 2.5 years of operation. In this paper, we review the MCSA flight electrical performance tests, data and computational modeling and discuss findings from data comparisons with the computational results.

    In this paper we present our 5-year-experience with a large-scale mentoring program for undergraduate medical students at the Ludwig Maximilians-Universität Munich (LMU). We implemented a two-tiered program with a peer-mentoring concept for preclinical students and a 1:1-mentoring concept for clinical students aided by a fully automated online-based matching algorithm. Approximately 20-30% of each student cohort participates in our voluntary mentoring program. Defining ideal program evaluation strategies, recruiting mentors from beyond the academic environment and accounting for the mentoring network reality remain challenging. We conclude that a two-tiered program is well accepted by students and faculty. In addition the online-based matching seems to be effective for large-scale mentoring programs. PMID:25699108

    Metachromatic leukodystrophy is a rare disorder of myelin metabolism. This degenerative disorder results from the accumulation of cerebroside sulfatide within the myelin sheath of central and peripheral nervous system, due to deficiency of aryl sulfatase A enzyme. We report a 5-year-old male child, who presented with regression of milestones, recurrent seizures and spasticity from second year of life. Initially neurodegenerative disorder was considered and the case was investigated with neuroimaging and enzyme levels. Computed tomography (CT) of the brain showed hypodensities in the corpus callosum and bilateral periventricular and deep cerebral white matter suggestive of neurodegenerative disorder. Subsequently, magnetic resonance imaging (MRI) of the brain was done, which showed symmetrical hyperintensities in the periventricular white matter with classical sparing of subcortical "U" fibers. The β-galactosidase enzyme activity was normal; however, the activity of aryl sulfatase A enzyme was undetectable, confirming the diagnosis of late infantile variant of metachromatic leukodystrophy.

    In 1987, the University of Sherbrooke's school of medicine implemented a student-centred, problem-based learning (PBL) curriculum. The experience of the first 5 years is reviewed; program goals, the schedule of learning activities, the instructional format and assessment of student learning are described. The new program is more demanding of teachers and requires better faculty training in pedagogy. No new financial resources have been available. The preclinical reform has led to revision of the clerkship, where sessions on clinical reasoning are now based on the PBL philosophy. Student reactions to the program are reported. The Sherbrooke experience has demonstrated that it is both possible and feasible to shift from a traditional to a problem-based curriculum. PMID:8477383

    NASA's Chandra X-Ray Observatory (CXO) was launched July 22, 1999 aboard the Space Shuttle Columbia, STS-93 mission. This image was produced by combining a dozen CXO observations made of a 130 light-year region in the center of the Milky Way over the last 5 years. The colors represent low (red), medium (green) and high (blue) energy x-rays. Thanks to Chandra's unique resolving power, astronomers have now been able to identify thousands of point-like x-ray sources due to neutron stars, black holes, white dwarfs, foreground stars, and background galaxies. What remains is a diffuse x-ray glow extending from the upper left to the lower right, along the direction of the disk of the galaxy.

    233 patients (53 men and 180 women) at the age of 60 years and older were treated in day gerontopsychiatric out-patient clinic for 5 years. 60-69 year old patients prevailed (146 individuals). Nearly all mental diseases characteristic for the old age were found in such patients; majority of patients suffered from schizophrenia (31.3%) and affective pathology (25.8%). Vascular form of dementia prevailed among the patients with dementia while atrophic degenerative dementia was rarely observed (2 patients). Syndromological distribution revealed that the main groups were formed by patients with depressions (41.6%) as well as individuals with neurosis- and psychopathic-like conditions (37.3%). Mental disorders with paranoid syndromes were observed in 8.6% of the patients. It is shown that day gerontopsychiatric out-patient clinic had some preferences in comparison with usual mental hospitals and psychoneurological out-patient clinic. PMID:9157762

    This case report demonstrates the full-mouth rehabilitation of a 45-year-old male patient with severe deep-bite by increasing vertical dimension. The technique of anterior maxillary osteotomy performed in the present situation has been found to be effective, requiring anterior and inferior repositioning of the anterior maxilla to provide an esthetic and functional implant supported fixed prosthesis. Four months after surgery, the fixation system was removed, and 6 dental implants were placed. The anterior and inferior movements of the segment allowed for natural tooth anatomy and size in the definitive implant supported partial fixed prosthesis. A satisfactory functional and esthetic result was obtained after 5 years of follow-up. PMID:27403066

    Central venous catheters provide an easy access for intravenous medications. Having a central line in place will relieve a child from the discomfort and danger of multiple regular intravenous lines for chemotherapy. The use of indwelling central venous catheters has become commonplace in the management of children undergoing oncological treatment. There are two types of central lines commonly used. There are Broviac catheters and Port-A-Cath (PAC) catheters. In the last 5 years we inserted 194 catheters in 175 children. We inserted 121 Broviac catheters and 73 PAC catheters. During the follow up of 39382 catheter days 44 complications were observed. In Broviac group the median follow up was 155 days and in PAC group was 230 days. We observed differences in the incidence between two devices. In Broviac group infections were more frequent and in PAC group other complications were more frequent than infections. PMID:18982750

    Twenty patients with unresectable hepatocellular carcinoma (HCC) were followed up to 5 years after transarterial radiotherapy with 90Y-resin particles. Diagnostic radioembolizations of 99mTc-macroaggregates facilitated scintigraphic assessment of activity distribution, dose evaluation and final procedural verification. The overall survival rates were 56, 38 and 14% (after 1, 2 and 3 years, resp.). Patients with unifocal HCC and a single feeding artery (n = 7) even presented 83, 67 and 40% (2 alive after 2.75 and 4 years). With multiple arteries (n = 7), the longest survival was 26 months. Patients with multifocal HCC survived up to 33 months after selective radioembolization. Quality of life was improved in all. Survival was positively correlated with absorbed dose but residual/recurrent tumour occurred even after > or = 300 Gy. Post-treatment symptoms were minimal (35 applications), pulmonary shunt rates were correctly predicted and pulmonary complications avoided. PMID:7997379

    The relevant documents of apoplectic urinary incontinence treated with acupuncture-moxibustion in recent 5 years have been collated and analyzed in aspect of current situation of acupuncture-moxibustion treatment, acupoint selection, manipulation and problems. The result indicates that the main therapy for this disease is acupuncture-moxibustion combined with electroacupuncture or other methods, and the acupuncture-moxibustion therapy is superior to the medicine. The clinical research has made considerable progress and the great importance has been attached to the research method. The main problems are low credibility of total quality, inconsistent curative course, incomplete case of illness, missing of quality control, disordered standards of clinical diagnosis and curative effect evaluation, varied observation index and phatic discussion of mechanism. It is suggested to carry on scientific research, enhance research lever, expand mind, innovate ideas, and establish uniformed standards of diagnosis and curative effect evaluation and observation index.

    This retrospective audit reviewed all ectopic pregnancies over a 5-year period in a district general hospital setting. Of 215 ectopic pregnancies identified, notes were available for 208 (97%). 202 cases were determined to have been diagnosed and managed as ectopic pregnancies. Six cases were excluded as they were pregnancies of unknown location managed as such. The proportion of patients managed non-surgically has increased following the introduction of our consultant-led early pregnancy assessment unit from 25% prior to 31% currently. The success rates have improved in both those managed expectantly (50%-73%) and those with methotrexate (75%-90%). There has been a corresponding drop in those managed surgically from 75% to 69%, and a reduction in negative laparoscopies from 13% to 6%. Provided recommended criteria and follow-up are adhered to, non-surgical management has been shown to have comparative safety to traditional surgical management with acceptable efficacy and patient acceptability.

    We describe the case of a 5-year-old girl whose abdominal pain and distension were caused by Wilms tumor of the kidney. Because of the bilateral nature of her disease, she was spared biopsy or initial nephrectomy as part of her treatment course. Rather, she was treated presumptively for Wilms tumor based primarily on radiologic findings. Neoadjuvant chemotherapy consisting of vincristine, dactinomycin and doxorubicin was given to facilitate nephron-sparing surgery for tumor resection. Her initial chemotherapeutic course was complicated by tumor lysis syndrome manifested by elevated serum uric acid and was treated effectively with hyperhydration and alkalization of intravenous fluids. The patient's disease responded well to chemotherapy, and she underwent successful tumor excision after 12 weeks of chemotherapy. The resected tumor was identified as anaplastic Wilms tumor, illustrating that pathologic identification of Wilms tumor is possible even after multiple cycles of neoadjuvant chemotherapy and marked tumor shrinkage.

    The US Department of Energy's (DOE) Resource Assessment Program produces scientific descriptions and assessments of the nation's renewable energy resources, such as solar energy. Information about the resources --- for example, how solar energy varies with location and climate --- is required to develop energy conversion technologies, design and site systems, and forecast the systems' performance. With information about resource availability and renewable energy system performance, DOE can assess the potential for renewable energy to contribute to the nation's energy supply as part of the long-term national energy strategy. This 5-year plan for fiscal years (FY) 1991 through 1995 gives the strategy to produce solar radiation resource characterizations and assessments under the DOE project at SERI. It is consistent with the mini-multiyear plan for resource assessment prepared by DOE in 1989 and incorporates the comments received at a project overview held in April 1990 at DOE Headquarters. 7 figs.

    A 5-year longitudinal study investigated the interrelationships among children's experiences of depressive symptoms, negative life events, explanatory style, and helplessness behaviors in social and achievement situations. The results revealed that early in childhood, negative events, but not explanatory style, predicted depressive symptoms; later in childhood, a pessimistic explanatory style emerged as a significant predictor of depressive symptoms, alone and in conjunction with negative events. When children suffered periods of depression, their explanatory styles not only deteriorated but remained pessimistic even after their depression subsided, presumably putting them at risk for future episodes of depression. Some children seem repeatedly prone to depressive symptoms over periods of at least 2 years. Depressed children consistently showed helpless behaviors in social and achievement settings.

    The Tokyo Dental College Oral Cancer Center was established on April 1st, 2006 at our Ichikawa General Hospital for the purpose of providing multimodal treatment for oral cancer. This report summarizes the Center's activities over the last 5 years. The total number of oral cancer patients treated was 360 (April 2006 to March 2011), with 205 primary cases. We investigated the following treatment-related items: 1) site, 2) age, 3) sex, 4) pathological examination, 5) staging, 6) systemic disorder, 7) double cancer, 8) treatment, and 9) prognosis. Out of 205 patients, 60% were men and 40% were women. Men in their 60s and women in their 80s were seen the most. The most common site was the tongue, at 42%, followed by the mandibular gingiva, maxillary gingiva, oral floor, and buccal mucosa. Squamous cell carcinomas were seen most frequently, at 94% (15% were stage I, 33% stage II, 15% stage III, and 34% stage IV). The most common treatment method was surgical treatment, at 83%. The 5-year survival rate at all stages was 85.4%. At the Oral Cancer Center, oral surgeons take the initiative in establishing treatment in cooperation with other departments and branches. Since the establishment of the Ambulatory Center for Maxillary Prosthetics in October 2011, 26 patients have undergone treatment. Related departments and branches work in teams, enabling comprehensive treatment, from the preoperative state to postoperative functional recovery. We wish to use these strengths to improve oral cancer treatment in Japan and will continue to work toward providing the best possible care for our patients. PMID:24521553

    Aim (1) To investigate the recurrence of periocular basal cell carcinoma (BCC) reported as completely excised on histology. (2) To identify risks associated with recurrence. (3) To recommend a rational follow-up protocol. Methods This is a cohort study by case note review of consecutive patients undergoing excision of periocular BCC between 2000 and 2006 at University Hospitals of Leicester. All lesions were excised with 3 mm clinical margin and the defect reconstructed only after the excision margin was declared clear. Results A total of 413 episodes of surgical excision were recorded for 270 patients over the 7-year period of 2000–2006. All of them have 5 years follow-up. Mean age 73.7 (±12.5). In all, 67% were nodular BCC and 45.4% located in the lower eyelid. The main outcome measure was the recurrence rate. None of the patients with primary nodular BCC suffered recurrence. The recurrence rate for primary morphoeaform BCC following complete excision is 3.8%. In total, 8.1% of patients had several lesions simultaneously whereas 7.8% patients had BCC in multiple locations subsequently (metachronous). Three patients who had previously recurrent BCC (rBCC) treated elsewhere or not using this method had orbital/lacrimal drainage system involvement requiring exenteration. Conclusion We recommend that patients with a single, completely excised primary solid or nodular BCC can be discharged after one 6-monthly review, although they should be instructed to monitor for the development of further lesions. The incidence of recurrence for primary morphoeaform BCC is 3.8% and for rBCC is 3.6% over 5 years and these patients should stay under review for this period. PMID:23154501

    Children are at risk for developing posttraumatic stress disorder (PTSD) due to experiencing or living in a disaster area. The factors that increase the likelihood of a child developing PTSD need further clarification. We studied the factors associated with PTSD among children who experienced the tsunami in Sumatra, Indonesia. We conducted a cross sectional study in 2 subdistricts of Sumatra 5 years after experiencing a tsunami. Children aged 7-13 years were enrolled using stratified cluster sampling. A tsunami-modified version of The PsySTART Rapid Triage System was used to question children about their tsunami-specific traumatic experiences. Trauma symptoms were evaluated using the Trauma Symptom Checklist For Children (TSCC). The diagnosis of PTSD was made using the Child PTSD Symptom Scale (CPSS) and DSM-IV criteria. The data were analyzed with chi-square tests and multivariate logistic regression analysis with 95% confidence intervals (CI). A total of 262 children were enrolled in this study. The prevalence of PTSD in these children was 20.6%. On multivariate analysis, having experienced a delay in evacuation (PR = 4.5; 95% CI: 2.794-13.80; p < 0.001) and being unable to escape (PR = 13.07; 95% CI: 5.884-64; p < 0.001) were significantly associated with PTSD 5 years after the tsunami. Children who experienced a traumatic event in which they were unable to escape or when there is a delay in evacuation are at risk of developing PTSD and need appropriate treatment. PMID:26863863

    We used data from a Scandinavian prospective multicenter study to investigate if smoking in pregnancy may have an adverse effect on the child's mental and motor abilities. Eligible for enrolment were para I and 2 women with a singleton pregnancy, who resided in one of the study areas and could be registered before the 20th gestational week. Women were classified as 'smokers' or 'non-smokers' at study start. At 13 months, 376 children (124 children of smokers) were evaluated with the Bayley Scales of Infant Development. At this age, children of smokers and non-smokers performed equally well. At 5 years, 369 children (132 children of smokers) were tested with the Wechsler Preschool and Primary Scales of Intelligence Revised (WPPSI-R), and 362 children with the Peabody Developmental Motor Scales (PDMS). Children of smokers had an increased risk of getting a WPPSI-R score below the median value of the population (OR = 2.1, 95% CI: 1.2-3.3), but the risk was reduced when we adjusted for maternal education (OR = 1.6, 95% CI: 0.9-3.7). Children of smokers had an increased risk of getting a test score below the median population value on the subscale 'balance' from PDMS (OR = 1.8, 95% CI: 1.2-2.8). Thus, we found that smoking in pregnancy was associated with a small, but demonstrable adverse effect on the child's balance at 5 years, whereas the negative effect on cognitive function did not reach statistical significance, when we adjusted for the mother's level of education.

    Background Foreign bodies (FBs) in the upper gastrointestinal tract are produced chiefly by accidental swallowing but rarely produce symptoms. Removal of FBs is not an infrequent challenge for upper gastrointestinal endoscopy. The aim of this study is to elicit our experience in a 5-year period in dealing with FBs in the upper gastrointestinal tract using upper endoscopy. Methods This retrospective study was conducted at Zagazig University Hospitals, Egypt, over a 5-year period. We reviewed all patients’ files with full notations on age, sex, type of FB and its anatomical location, treatments, and outcomes (complications, success rates, and mortalities). Patients with incomplete files and those with FBs not identified at the endoscopic examination were excluded. Results A total of 45 patients were identified. Their ages ranged from 6 months to 102 years. Slight male predominance was noticed (53.3%). The most frequent presentation was a history of FB ingestion without any associated manifestations (44.4%). Coins were the most commonly encountered FBs (14/45). Esophagus was the most common site of trapping (27/45). The overall success rate was 95.6% (43/45). Upper endoscopy successfully resolved the problem by either FB removal (41/43) or dislodgment of the impacted fleshy meat to the stomach (2/43). Two cases were referred for surgical removal. The rate of complications was 6.7%. Furthermore, no mortalities due to FB ingestion or removal had been reported throughout the study. Conclusion Our experience with FB removal emphasizes its importance and ease when performed by experienced hands, at well-equipped endoscopy units, and under conscious sedation in most cases, with high success rates and minor complications.

    Background In 2004, Afghanistan pioneered a balanced scorecard (BSC) performance system to manage the delivery of primary health care services. This study examines the trends of 29 key performance indicators over a 5-year period between 2004 and 2008. Methods and Findings Independent evaluations of performance in six domains were conducted annually through 5,500 patient observations and exit interviews and 1,500 provider interviews in >600 facilities selected by stratified random sampling in each province. Generalized estimating equation (GEE) models were used to assess trends in BSC parameters. There was a progressive improvement in the national median scores scaled from 0–100 between 2004 and 2008 in all six domains: patient and community satisfaction of services (65.3–84.5, p<0.0001); provider satisfaction (65.4–79.2, p<0.01); capacity for service provision (47.4–76.4, p<0.0001); quality of services (40.5–67.4, p<0.0001); and overall vision for pro-poor and pro-female health services (52.0–52.6). The financial domain also showed improvement until 2007 (84.4–95.7, p<0.01), after which user fees were eliminated. By 2008, all provinces achieved the upper benchmark of national median set in 2004. Conclusions The BSC has been successfully employed to assess and improve health service capacity and service delivery using performance benchmarking during the 5-year period. However, scorecard reconfigurations are needed to integrate effectiveness and efficiency measures and accommodate changes in health systems policy and strategy architecture to ensure its continued relevance and effectiveness as a comprehensive health system performance measure. The process of BSC design and implementation can serve as a valuable prototype for health policy planners managing performance in similar health care contexts.

    Anaemia in children is a public health concern in Mexico; Federal food assistance programmes are being implemented to prevent it. We undertook this research to investigate the indirect association between food assistance programmes (FAP) and anaemia through dietary and socio-economic conditions of beneficiary children. A structural equation model (SEM) was constructed to assess associations among FAP, dietary and socio-economic conditions, as well as anaemia. A cross-sectional comparative study was conducted based on a sample of 1214 households with children <5 years old, beneficiaries of two FAP: Prospera and rescue from malnutrition with amaranth (RMA) and a comparison group in San Luis Potosí, Mexico. The SEM and a decomposition effect analysis revealed the existence of a significant indirect association of FAP on the prevalence of anaemia via dietary and socio-economic conditions in children under 5 years old. The Prospera assistance programme showed a significant indirect positive association with the prevalence of anaemia (standard coefficient=0·027, P<0·031), and the RMA programme showed a significant indirect negative association with the prevalence of anaemia (standard coefficient=-0·029, P=0·047). There was a direct association between FAP and dietary and socio-economic conditions. FAP could indirectly modify the prevalence of anaemia in young children with a direct improvement on dietary and socio-economic conditions. The unexpected finding of the association between RMA, dietary and socio-economic conditions and the prevalence of anaemia reflects differences in the focus of the programmes. PMID:27545977

    In Japan, problem-based learning (PBL) is a relatively new method of educating medical students that is reforming the face of medical education throughout the world, including Asia. It shifts from teacher-centered learning strategies (for example, lectures in large auditoriums) to student-centered, self-directed learning methods (for example, active discussions and problem-solving by students in small groups under the guidance of faculty tutors). Upon a recommendation by the Japan Model Core Curriculum, Saga Medical School introduced a PBL curriculum 5 years ago. A full PBL curriculum was adopted from the McMaster model through Hawaii. A description of how PBL was implemented into the 3rd and 4th year (Phase III curriculum) is given. The overall result has been good. Students who experienced PBL had increased scores on the National Medical License Exam, and Saga increased its ranking from 56th to 19th of the 80 medical schools in Japan. A key step was introduction of the educational scaffolding in PBL Step 0. Students were allowed to see page one of the PBL case, containing the chief complaint, on the weekend before meeting in small groups. Despite a perceived overall benefit to student learning, symptoms of superficial discussions by students have been observed recently. How this may be caused by poor case design is discussed. Other problems, including "silent tutors" and increased faculty workload, are discussed. It is concluded that after 5 years, Saga's implementation of a PBL curriculum has been successful. However, many additional issues, including motivation of students and preparation for PBL in the first 2 years, must still be resolved in the future. This is the first description of the positive and negative outcomes associated with the reform of medical education and the introduction of PBL to a traditional medical school curriculum in Japan.

    Purpose To determine whether stereopsis of infants treated for monocular cataracts varies with the type of optical correction used. Design Randomized prospective clinical trial Methods The Infant Aphakia Treatment Study randomized 114 patients with unilateral cataracts at age 1 to 7 months to either primary intraocular lens (IOL) or contact lens correction. At 4.5 years of age a masked examiner assessed stereopsis on these patients using three different tests: 1) Frisby; 2) Randot Preschool; and 3) Titmus fly. Results Twenty-eight patients (25%) had a positive response to at least one of the stereopsis tests. There was no statistically significant difference in stereopsis between the two treatment groups. Frisby (contact lens, 6 (11%); IOL, 7 (13%); p=0.99), Randot (contact lens, 3 (6%); IOL, 1 (2%); p=0.62) or Titmus: (contact lens, 8 (15%); IOL, 13 (23%); p=0.34). The median age at surgery for patients with stereopsis was younger than for those without stereopsis (1.2 versus 2.4 months; p=0.002). The median visual acuity for patients with stereopsis was better than for those without stereopsis (20/40 vs. 20/252; p=0.0003). Conclusion The type of optical correction did not influence stereopsis outcomes. However, two other factors did: age at surgery and visual acuity in the treated eye at age 4.5 years. Early surgery for unilateral congenital cataract and the presence of visual acuity better than or equal to 20/40 appear to be more important than the type of initial optical correction used for the development of stereopsis.

    Background: Since Tehran University of Medical Sciences (TUMS) has the oldest and highest number of research centers among all Iranian medical universities, this study was conducted to evaluate scientific output of research centers affiliated to Tehran University of Medical Sciences (TUMS) using scientometric indices and the affecting factors. Moreover, a number of scientometric indicators were introduced. Methods: This cross-sectional study was performed to evaluate a 5-year scientific performance of research centers of TUMS. Data were collected through questionnaires, annual evaluation reports of the Ministry of Health, and also from Scopus database. We used appropriate measures of central tendency and variation for descriptive analyses. Moreover, uni-and multi-variable linear regression were used to evaluate the effect of independent factors on the scientific output of the centers. Results: The medians of the numbers of papers and books during a 5-year period were 150.5 and 2.5 respectively. The median of the "articles per researcher" was 19.1. Based on multiple linear regression, younger age centers (p=0.001), having a separate budget line (p=0.016), and number of research personnel (p<0.001) had a direct significant correlation with the number of articles while real properties had a reverse significant correlation with it (p=0.004). Conclusion: The results can help policy makers and research managers to allocate sufficient resources to improve current situation of the centers. Newly adopted and effective scientometric indices are is suggested to be used to evaluate scientific outputs and functions of these centers. PMID:26157724

    Background: INDUS knee implant has been designed as per the anatomical morphology of the Indian population and has shown good clinical outcome in short term studies. The purpose of the present study was to report the midterm survivorship and clinical outcome of this implant. Materials and Methods: Two hundred and twenty three primary total knee arthroplasties in 209 consecutive patients using the INDUS knee prosthesis were prospectively enrolled. There were 145 females (155 knees) and 64 males (68 knees) with a mean age of 69.95 years (range 42–86 years). Annual followup with clinical and radiological examination was conducted, and a survivorship analysis was done using the Kaplan–Meier analysis. Results: Mean followup was 5.8 years (range 5–6.5 years). Eleven patients died while eight were lost to followup and a total of 204 knees were available for followup. The mean knee flexion improved from preoperative 110.4° ± 11.24° (range 60°–130°) to 128.17° ± 8.32° (range 100°–140°) at the final followup. The mean knee score improved from 40.1 ± 10.7 to 90.3 ± 5.34 while the function score improved from 44.35 ± 12.9 to 89.58 ± 7.43. Two patient developed infection and required revision. The Kaplan–Meier analysis reported a survivorship of 98.6% (confidence interval 95.7–99.6%) at the end for 5 years for INDUS knee prosthesis. Conclusion: INDUS knee prosthesis has excellent survivorship with a good clinical outcome and low failure rate. PMID:27053801

    One of the unsolved problems in the characterization of the optimal entanglement witnesses is the existence of optimal witnesses acting on bipartite Hilbert spaces H{sub m,n}=C{sup m} x C{sup n} such that the product vectors obeying =0 do not span H{sub m,n}. So far, the only known examples of such witnesses were found among indecomposable witnesses, one of them being the witness corresponding to the Choi map. However, it remains an open question whether decomposable witnesses exist without the property of spanning. Here we answer this question affirmatively, providing systematic examples of such witnesses. Then, we generalize some of the recently obtained results on the characterization of 2 x n optimal decomposable witnesses [R. Augusiak et al., J. Phys. A 44, 212001 (2011)] to finite-dimensional Hilbert spaces H{sub m,n} with m,n{>=}3.

    Dietary restriction (DR) without malnutrition is associated with longevity in various organisms. However, it has also been shown that reduced calorie intake is often ineffective in extending life span. Selecting optimal dietary regimens for DR studies is complicated, as the same regimen may lead to different outcomes depending on genotype and environmental factors. Recent studies suggested that interventions such as moderate protein restriction with or without adequate nutrition (e.g., particular amino acids or carbohydrates) may have additional beneficial effects mediated by certain metabolic and hormonal factors implicated in the biology of aging, regardless of total calorie intake. In particular, it was shown that restriction of a single amino acid, methionine, can mimic the effects of DR and extend life span in various model organisms. We discuss the beneficial effects of a methionine-restricted diet, the molecular pathways involved, and the use of this regimen in longevity interventions. PMID:26663138

  12. The Cost of Uncertain Life Span*

    2012-01-01

    A considerable amount of uncertainty surrounds the length of human life. The standard deviation in adult life span is about 15 years in the U.S., and theory and evidence suggest it is costly. I calibrate a utility-theoretic model of preferences over length of life and show that one fewer year in standard deviation is worth about half a mean life year. Differences in the standard deviation exacerbate cross-sectional differences in life expectancy between the U.S. and other industrialized countries, between rich and poor countries, and among poor countries. Accounting for the cost of life-span variance also appears to amplify recently discovered patterns of convergence in world average human well-being. This is partly for methodological reasons and partly because unconditional variance in human length of life, primarily the component due to infant mortality, has exhibited even more convergence than life expectancy.

    Guttmann, Anthony J.; Rogers, Mathew D.

    2012-12-01

    We define the notion of a spanning tree generating function (STGF) ∑anzn, which gives the spanning tree constant when evaluated at z = 1, and gives the lattice Green function (LGF) when differentiated. By making use of known results for logarithmic Mahler measures of certain Laurent polynomials, and proving new results, we express the STGFs as hypergeometric functions for all regular two and three dimensional lattices (and one higher-dimensional lattice). This gives closed form expressions for the spanning tree constants for all such lattices, which were previously largely unknown in all but one three-dimensional case. We show for all lattices that these can also be represented as Dirichlet L-series. Making the connection between STGFs and LGFs produces integral identities and hypergeometric connections, some of which appear to be new. This article is part of ‘Lattice models and integrability’, a special issue of Journal of Physics A: Mathematical and Theoretical in honour of F Y Wu's 80th birthday.

    The sovereign debt crisis in the euro area has not yet been solved and recent developments in Spain and Italy have further deteriorated the situation. In this paper we develop a new approach to analyze the ongoing Eurozone crisis. Firstly, we use Maximum Spanning Trees to analyze the topological properties of government bond rates’ dynamics. Secondly, we combine the information given by both Maximum and Minimum Spanning Trees to obtain a measure of market dissimilarity or disintegration. Thirdly, we extend this measure to include a convenient distance not limited to the interval [0, 2]. Our empirical results show that Maximum Spanning Tree gives an adequate description of the separation of the euro area into two distinct groups: those countries strongly affected by the crisis and those that have remained resilient during this period. The measures of market dissimilarity also reveal a persistent separation of these two groups and, according to our second measure, this separation strongly increased during the period July 2009-March 2012.

  3. Digit Span is (mostly) related linearly to general intelligence: Every extra bit of span counts.

    PubMed

    Gignac, Gilles E; Weiss, Lawrence G

    2015-12-01

    Historically, Digit Span has been regarded as a relatively poor indicator of general intellectual functioning (g). In fact, Wechsler (1958) contended that beyond an average level of Digit Span performance, there was little benefit to possessing a greater memory span. Although Wechsler's position does not appear to have ever been tested empirically, it does appear to have become clinical lore. Consequently, the purpose of this investigation was to test Wechsler's contention on the Wechsler Adult Intelligence Scale-Fourth Edition normative sample (N = 1,800; ages: 16 - 69). Based on linear and nonlinear contrast analyses of means, as well as linear and nonlinear bifactor model analyses, all 3 Digit Span indicators (LDSF, LDSB, and LDSS) were found to exhibit primarily linear associations with FSIQ/g. Thus, the commonly held position that Digit Span performance beyond an average level is not indicative of greater intellectual functioning was not supported. The results are discussed in light of the increasing evidence across multiple domains that memory span plays an important role in intellectual functioning. PMID:25774642

    Blood transfusion and iron chelation currently represent a supportive therapy to manage anemia, vasculopathy and vaso-occlusion crises in Sickle-Cell-Disease. Here we describe the first 5-year long-term randomized clinical trial comparing Deferiprone versus Deferoxamine in patients with Sickle-Cell-Disease. The results of this study show that Deferiprone has the same effectiveness as Deferoxamine in decreasing body iron burden, measured as repeated measurements of serum ferritin concentrations on the same patient over 5-years and analyzed according to the linear mixed-effects model (LMM) (p=0.822). Both chelators are able to decrease, significantly, serum ferritin concentrations, during 5-years, without any effect on safety (p=0.005). Moreover, although the basal serum ferritin levels were higher in transfused compared with non-transfused group (p=0.031), the changes over time in serum ferritin levels were not statistically significantly different between transfused and non-transfused cohort of patients (p=0.389). Kaplan-Meier curve, during 5-years of study, suggests that Deferiprone does not alter survival in comparison with Deferoxamine (p=0.38). In conclusion, long-term iron chelation therapy with Deferiprone was associated with efficacy and safety similar to that of Deferoxamine. Therefore, in patients with Sickle-Cell-Disease, Deferiprone may represent an effective long-term treatment option. PMID:24814618

    The paper describes the numerical program, PIPESIN, that simulates the behavior of a pipeline placed on an erodible seabed. PIPEline Seabed INteraction from installation until a stable pipeline seabed configuration has occurred is simulated in the time domain including all important physical processes. The program is the result of the joint research project, ``Free Span Development and Self-lowering of Offshore Pipelines`` sponsored by EU and a group of companies and carried out by the Danish Hydraulic Institute and Delft Hydraulics. The basic modules of PIPESIN are described. The description of the scouring processes has been based on and verified through physical model tests carried out as part of the research project. The program simulates a section of the pipeline (typically 500 m) in the time domain, the main input being time series of the waves and current. The main results include predictions of the onset of free spans, their length distribution, their variation in time, and the lowering of the pipeline as function of time.

Sixty-two 5-year-old nursery schoolchildren participated in this study on the relation between the viscosity of saliva and flow rate and glucose retention. Each child was instructed to rinse his/her mouth with a glucose solution (0.5 M, 5 ml) and then to spit out. Three minutes after rinsing, glucose retention was determined. Resting saliva was collected by a natural outflow method, then the flow rate was determined. A rotational viscometer was used to determine the viscosity. Glucose retention and flow rate were correlated at the left maxillary primary molars, and glucose retention and viscosity were correlated at the maxillary central primary incisors. It was concluded that glucose retention after glucose mouth rinsing was site-specific, and that glucose retention and the index of decayed, missing and filled primary teeth (dmft) were slightly correlated with the salivary viscosity and flow rate.

    Reported are estimates of the prevalence in developing countries of physiologically significant vitamin A deficiency and the number of attributable deaths. The WHO classification of countries by the severity and extent of xerophthalmia was used to categorize developing countries by likely risk of subclinical vitamin A deficiency. Using vital statistics compiled by UNICEF, we derived population figures and mortality rates for under-5-year-olds. The findings of vitamin A supplementation trials were applied to populations at-risk of endemic vitamin A deficiency to estimate the potential impact of improved vitamin A nutriture in reducing mortality during preschool years. Worldwide, over 124 million children are estimated to be vitamin A deficient. Improved vitamin A nutriture would be expected to prevent approximately 1-2 million deaths annually among children aged 1-4 years. An additional 0.25-0.5 million deaths may be averted if improved vitamin A nutriture can be achieved during the latter half of infancy. Improved vitamin A nutriture alone could prevent 1.3-2.5 million of the nearly 8 million late infancy and preschool-age child deaths that occur each year in the highest-risk developing countries.

    Pulse wave velocity is a reliable marker of arterial compliance. Stiffness of large and elastic arteries leads to a faster propagation of pulse wave. The aim of this study was to evaluate changes in arterial distensibility using antihypertensive drugs. This treatment focused on the inhibition of the renin-angiotensin-aldosterone system and the changes produced in blood pressure. Measurements were taken at baseline and throughout 60 months in 66 previously untreated hypertensive patients (22 men and 44 women, aged 54 +/- 9.5 years, range 38-73 years at baseline). All patients received either angiotensin-converting enzyme inhibitors or, in case of adverse effects, angiotensin receptor blockers. To control blood pressure, diuretics, calcium channel blocking agents, or beta blockers were added when appropriate. Statistical analysis was performed by means of ANOVA with alpha = 0.05. Systolic and diastolic blood pressure decreased during the first year without significant changes thereafter. There were no significant changes in pulse pressure. Pulse wave velocity showed a continuous and significant decrease throughout the follow-up period, but its reduction since the third year was more evident than the decrease in systolic and diastolic blood pressure (p < 0.0001 for both). This observation could be related to changes in arterial remodeling probably due to angiotensin-converting enzyme inhibition or renin angiotensin system blockade. Further investigations are needed to establish this relationship. PMID:16896271

    In typically developing children, drawing development occurs in stages from uncontrolled strokes to complex drawing. In this study, we examined drawing development in children with neurodevelopmental delay (NDD). In order to do so, we observed the influence of age, intraventricular hemorrhage (IVH) and gender on the development of drawing skills. The sample consisted of 52 children with NDD, aged 2 years and 6 months to 5 years. All children were hospitalized for multidisciplinary team monitoring and developmental support. The evaluation of drawing development was administered by giving each child a blank A4 paper and the instruction to draw anything they wanted. All of the drawings were scored satisfactory or unsatisfactory. Descriptive statistics was employed on all relevant data to show results in frequencies and percentages. In order to determine differences between groups, the χ2-test was administered. The results showed greatest difference in drawing in children aged from 3 years to 3 years and 11 months. Children with lower IVH had better drawing scores than children with higher IVH levels. According to gender dissimilarities, a difference was found showing girls to have better drawing skills than boys. All study results pointed to the importance of early rehabilitation and continuous structured work with children with NDD. PMID:26415307

    Children (405), initially of average age 11.5 years, recorded all food and drinks consumed for three consecutive days (with an interview on the fourth day) on five separate occasions over a 2-year period. Food tables (Paul & Southgate, 1978) enabled nutrient intakes to be calculated. The data collected were found to be of high reliability (Hackett et al. 1983). The mean energy intakes showed broad agreement with other recent British dietary surveys but were well below those recorded in the prewar study by Widdowson (1947) and the FAO/WHO (1973) recommended levels. They were slightly below the current Department of Health and Social Security (DHSS; 1979) recommended intakes. Over the 2-year period, the energy intake of the boys increased by 13% compared with an increase of only 7% in the girls. The iron and vitamin A intakes of all groups of children were low compared with current recommendations (DHSS, 1979). This seems to be a result of falling energy intake. Mean calcium intakes were also only marginally in excess of the recommended intake, and those of most of the girls would fall below the recommendation if the proposal to end the fortification of flour (DHSS, 1981) is implemented.

    Some studies, so far limited in number, suggest the existence of procedural metacognition in young children, that is, the practical capacity to monitor and control one’s own cognitive activity in a given task. The link between procedural metacognition and false belief understanding is currently under theoretical discussion. If data with primates seem to indicate that procedural metacognition and false belief understanding are not related, no study in developmental psychology has investigated this relation in young children. The present paper aims, first, to supplement the findings concerning young children’s abilities to monitor and control their uncertainty (procedural metacognition) and, second, to explore the relation between procedural metacognition and false belief understanding. To examine this, 82 3- to 5-year-old children were presented with an opt-out task and with 3 false belief tasks. Results show that children can rely on procedural metacognition to evaluate their perceptual access to information, and that success in false belief tasks does not seem related to success in the task we used to evaluate procedural metacognition. These results are coherent with a procedural view of metacognition, and are discussed in the light of recent data from primatology and developmental psychology. PMID:26517260

    We constrain the primordial non-Gaussianity parameter of the local model f{sub NL} using the skewness power spectrum associated with the two-to-one cumulant correlator of cosmic microwave background temperature anisotropies. This bispectrum-related power spectrum was constructed after weighting the temperature map with the appropriate window functions to form an estimator that probes the multipolar dependence of the underlying bispectrum associated with the primordial non-Gaussianity. We also estimate a separate skewness power spectrum sensitive more strongly to unresolved point sources. When compared to previous attempts at measuring the primordial non-Gaussianity with WMAP data, our estimators have the main advantage that we do not collapse information to a single number. When model fitting the two-to-one skewness power spectrum, we make use of bispectra generated by the primordial non-Gaussianity, radio point sources, and lensing-secondary correlation. We analyze Q, V, and W-band WMAP 5-year data using the KQ75 mask out to l{sub max}=600. Using V and W-band data and marginalizing over model parameters related to point sources and lensing-secondary bispectrum, our overall and preferred constraint on f{sub NL} is 11.0{+-}23.7 at the 68% confidence level (-36.4

    Between 1989 and 1993, 255 tumor biopsies representing 4 tumor histologies (melanoma, breast cancer, colon cancer and renal cell cancer) were received by the Surgery Branch of the National Cancer Institute. Tumor-infiltrating lymphocytes (TIL) were grown from single-cell suspensions of tumor biopsies over the course of 30-45 days. The TIL were grown in medium containing IL-2. To obtain numbers suitable for therapy (>10(11)), TIL were expanded using a large-scale system of cell culture and harvesting. While the largest number of biopsies was obtained from melanoma patients, TIL were successfully grown from 160 of 255 tumor biopsies representing all 4 histologies. Under the culture conditions employed, several characteristics of TIL expansion were observed. The cell surface phenotype of TIL which grew out from the tumor biopsies was generally a mix of CD3+/CD4+ or CD3+/CD8+ lymphocytes. Only TIL from melanoma biopsies were found to be consistently cytolytic and, in many cases, lysed autologous tumor cells preferentially. Interestingly, TIL derived from extra-nodal sites of metastatic melanoma biopsies (subcutaneous, lung, bowel; 36 of 67, 54%) were more likely to have these cytolytic characteristics than TIL derived from tumor-involved lymph node biopsies (7 of 39, 18%). The present study summarizes 5 years of laboratory effort and validates the technologies developed for the large-scale growth and harvesting of TIL. In addition, it summarizes the laboratory effort supporting previously published clinical reports on TIL from our group. PMID:8621219

    The situation of waste management in Tehran was a typical example of it in developing countries. The amount of municipal solid waste has been increasing and the city has depended on landfill for municipal solid waste management. However, in recent years, various measures have been taken by the city, such as collecting recyclables at the source and increasing the capacity of waste-processing facilities. As a result, significant changes in the waste stream are starting to occur. This study investigated the nature of, and reasons for, the marked changes in the waste stream from 2008 to 2012 by analysing the municipal solid waste statistics published by the Tehran Waste Management Organization in 2013 and survey data on the physical composition of the municipal solid waste. The following trends were identified: Although the generation of municipal solid waste increased by 10% during the 5-year period, the amount of waste directly disposed of to landfill halved and resource recovery almost doubled. An increase in the capacity of a waste-processing facility contributed significantly to these changes. The biodegradable fraction going to landfill was estimated by using the quantity and the composition of each input to the landfill. The estimated result in 2012 decreased to 49% of its value in 2008.

    One hundred and seventy-three underwent proximal gastric vagotomy for duodenal ulceration over a 6-year period. One hundred and fifteen of these have been followed up for 1-5 years. The operative mortality was nil and the result was satisfactory in 91 per cent. The incidence of side effects was small, notably that of dumping being 2.4 per cent and of diarrhoea, 3.6 per cent. Incidence of postoperative heartburn was reduced from 13 per cent to 4 per cent by the introduction of hepatic interposition. The incidence of recurrent ulceration was 5.1 per cent after an average interval of 2 years and that of new gastric ulceration 2.6 per cent after an average of 4 years. There were no recurrent ulcers in those who had peroperative Burge tests, although secretory studies showed no difference between those tested and those not tested. Most recurrences occurred in the earliest cases operated on before Burge testing was introduced and when only 2 cm of the lower oesophagus were exposed. PMID:420970

    The primary purpose of this study was to examine the dimensionality and reliability of letter writing skills in preschool children with the aim of determining whether a sequence existed in how children learn to write the letters of the alphabet. Additionally, we examined gender differences in the development of letter writing skills. 471 children aged 3 to 5 years old completed a letter writing task. Results from factor analyses indicated that letter writing represented a unidimensional skill. Similar to research findings that the development of letter-names and letter-sound knowledge varies in acquisition, our findings indicate that the ability to write some letters is acquired earlier than the ability to write other letters. Although there appears to be an approximate sequence for the easiest and most difficult letters, there appears to be a less clear sequence for letters in the middle stages of development. Overall, girls had higher letter writing scores compared to boys. Gender differences regarding difficulty writing specific letters was less conclusive; however, results indicated that when controlling for ability level, girls had a higher probability of writing a letter correctly than boys. Implications of these findings for the assessment and instruction of letter writing are discussed. PMID:26346443

    The definition and derivation of a 5-year, 0.125deg, 3-hourly atmospheric forcing dataset for the South America continent is described which is appropriate for use in a Land Data Assimilation System and which, because of the limited surface observational networks available in this region, uses remotely sensed data merged with surface observations as the basis for the precipitation and downward shortwave radiation fields. The quality of this data set is evaluated against available surface observations. There are regional difference in the biases for all variables in the dataset, with biases in precipitation of the order 0-1 mm/day and RMSE of 5-15 mm/day, biases in surface solar radiation of the order 10 W/sq m and RMSE of 20 W/sq m, positive biases in temperature typically between 0 and 4 K, depending on region, and positive biases in specific humidity around 2-3 g/Kg in tropical regions and negative biases around 1-2 g/Kg further south.

    Objective: To evaluate the results of photorefractive keratectomy (PRK) with mitomycin C in myopia correction after five years. Methods: This is a cross sectional study which included 145 eyes of 74 patients in 18 to 51 years age group that were undergoing Photorefractive keratectomy with mitomycin C using Allegretto Wave Eye-Q 400-Hz excimer laser platform in Markazi Eye Center, Tehran, Iran. All the surgical procedures were performed by the same surgeon. After five years follow-up evaluation including BCVA, UCVA, Refractive error measurement and external eye examination was performed. Results: The mean diopter of spherical equivalent before surgery was -3.40±1.73. The following findings were obtained after 5 years follow up visit: The mean spherical equivalent value: -0.08±0.40, the mean: Log MARUCVA: 0.02±0.07, the mean Log MAR BCVA: 0.00±0.04. Conclusion: PRK is an effective, safe and predictable method used to correct myopia. The wave front-optimized algorithm of the Allegretto Wave Eye-Q 400-Hz excimer laser platform demonstrated good refractive and visual results. Presence of variables such as gender, age and astigmatism before operation have no significant impact on the result of this operation. PMID:27022380

    Currently, chromatography (GC but more commonly HPLC) is the analytical method of choice for several hormones, either because the immunoassays suffer from extensive crossreactivity or because chromatography permits simultaneous measurements of hormones. However, sometimes the conventional detection systems with HPLC methods do not meet desired specificity. With the increase of robust and affordable LC-MS/MS systems, the next step forward in specificity was taken. LC-MS/MS is rapidly being incorporated in the endocrine laboratories. To be useful in the clinical diagnostic practice, it is of utmost importance that methods are both analytically and clinically vaidated, as until now, the majority of applications of LC-MS/MS in the clinical laboratories are 'home-made' methods, therefore special case must be taken. This review aims to focus on Clinical and Laboratory Standards Institute or comparable validated LC-MS/MS methods for targeted hormone analysis used for diagnostic purposes in human samples, published in the last 5 years.

    Bachelor of Midwifery programs in the state of Victoria, Australia commenced in 2002 through an affiliation of three universities in Melbourne named the 'Werna Naloo Bachelor of Midwifery consortium'. The approach allowed for collaborative synergies in program delivery through offering online 'consortium' units each semester in addition to on-campus content at each university. It is now 5 years since the first cohort of students commenced the course. During those years, members of the consortium have experienced a range of challenges and tensions. This paper provides a reflection by the course coordinators from two remaining members of the consortium, Australian Catholic University and Monash University. It explores issues confronted, regulation and registration, educational and clinical practice issues. In addition, the authors discuss course outcomes in terms of employment of graduates and their integration into the workforce, career development pathways and demand for the course. The authors conclude that the consortium has been successful and course outcomes positive with graduates successful in securing employment. Overall, the future for the Bachelor of Midwifery at both universities appears positive. PMID:17499037

    There is a growing international consensus that African health systems need to improve, but no agreement on how to accomplish this. From the perspective of modern quality improvement (QI), a central issue for low performance in these health systems is the relative neglect of health-care processes. Both health system leaders and international donors have focused their efforts elsewhere, producing noteworthy health gains. But these gains are at risk if health systems do not develop the capacity to study and improve care processes. Substantial experience with QI in Africa shows impressive potential for broad-based process improvement. But this experience also highlights the need for modifying these growing programs to incorporate a more rigorous learning component to address challenges that have emerged recently. The addition of a region-wide knowledge management program could increase the efficiency of each country's QI program by learning from the experiences of other programs. With a coordinated donor initiative, it is reasonable to project that within 5 years, evidence-based improvement will become a norm in health services, and African health systems will approach the model of a learning organization.

    The NASA Langley Research Center has sponsored research to develop generic repair techniques and processes for advanced graphite/epoxy (Gr/Ep) composites applicable to secondary structures for commercial transport aircraft. The long-term durability of such repairs is being addressed in a 10-year outdoor exposure program at the Langley Research Center. Details of the program and results of residual strength tests after 5 years of outdoor exposure are presented. Four repair methods are being evaluated. These include: (1) externally bolted aluminum-plus adhesive; (2) precured, bonded external Gr/Ep; (3) cure-in-place external Gr/Ep; and (4) cure-in-place flush Gr/Ep. Repaired specimens as well as undamaged and damaged unrepaired controls are being exposed outdoors for 1, 3, 5, 7, and 10 years. The residual tensile strength of stressed, unstressed, and fatigue specimens from each group is reported and compared with the tensile strength of baseline specimens which received no outdoor exposure. Identification of the commercial products and companies is used to describe adequately the test materials. The identification of these commercial products does not constitute endorsement, expressed or implied, of such products by the National Aeronautics and Space Administration.

    Executive function (EF) refers to a set of higher order cognitive processes that control and modulate cognition under continuously changing and multiple task demands. EF plays a central role in early childhood, is associated and predictive of important cognitive achievements and has been recognized as a significant aspect of school readiness. This study examines the efficacy of a group based intervention for 5-year-old children that focuses on basic components of EF (working memory, inhibitory control, cognitive flexibility). The intervention included 12 sessions, lasted 1 month and used low-cost materials. Seventy-five children took part in the study. The results indicate that the children who attended the intervention outperformed controls in simple and more complex EF tasks. Specifically, these children exhibited increased abilities to delay gratification, to control on-going responses, to process and update information, and to manage high cognitive conflict. These results suggest the possibility that this intervention, which may be easily implemented in educational services, can promote EF during preschool period before the entrance in primary school.

    Care practices and risk factors for diarrhea among impoverished communities across Mesoamerica are unknown. Using Salud Mesoamérica Initiative baseline data, collected 2011-2013, we assessed the prevalence of diarrhea, adherence to evidence-based treatment guidelines, and potential diarrhea correlates in poor and indigenous communities across Mesoamerica. This study surveyed 14,500 children under 5 years of age in poor areas of El Salvador, Guatemala, Mexico (Chiapas State), Nicaragua, and Panama. We compared diarrhea prevalence and treatment modalities using χ(2) tests and used multivariable Poisson regression models to calculate adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) for potential correlates of diarrhea. The 2-week point prevalence of diarrhea was 13% overall, with significant differences between countries (P < 0.05). Approximately one-third of diarrheal children were given oral rehydration solution and less than 3% were given zinc. Approximately 18% were given much less to drink than usual or nothing to drink at all. Antimotility medication was given to 17% of diarrheal children, while antibiotics were inappropriately given to 36%. In a multivariable regression model, compared with children 0-5 months, those 6-23 months had a 49% increased risk for diarrhea (aRR = 1.49, 95% CI = 1.15, 1.95). Our results call for programs to examine and remedy low adherence to evidence-based treatment guidelines. PMID:26787152

    We present a case of caustic ingestion by a 1.5-year-old boy. The caustic agent was drain opener which is a strong alkaline substance. Children in Iran and many other countries are still exposed to not "child proof" (child resistant packaging) toxic substance containers. Ingestion of caustic agents may lead to necrosis, perforation, and strictures. Substances that are ingested more frequently are liquid alkali material which causes severe, deep liquefaction necrosis. Common signs and symptoms of caustic agents are vomiting, drooling, refusal to drink, oral burns, stridor, hematemesis, dyspnea, dysphagia and abdominal pain. Even if no oropharyngeal lesion is seen, a significant esophageal injury which can lead to perforation and stricture cannot be ruled out. If abdominal pain or rigidity, substernal, chest or back pain exists, visceral perforation should be considered. The first thing to be checked is airway assessment. A lot of patients should be admitted to intensive care unit, and endoscopic evaluation, surgical intervention, long-term hospitalization, and worsening quality of life or among the complications. Preventive measures especially at the country level and approving proper legislation for obligating the related industries to produce child proof containers for house hold toxic products are the urgent measures to be followed by all of us.

    Nearly 95% of global burn deaths and disabilities are estimated to occur in low and middle income countries of the world. Burns are extremely common and are a major public health problem in a developing country like India. The purpose of this study was to record and evaluate the causes and the magnitude of the fatal burns retrospectively. An analysis of autopsy records revealed 2225 (10.7%) cases of burns among the total autopsies done over 5 years period (1st January 2008-27th November 2012) in the mortuary of Forensic Medicine & Toxicology, K.G.M.U., Lucknow. The majority of deaths (88.8%) occurred between 10 and 49 years of age group with a preponderance of females (87.5%). The flame burns were seen in 60.1% of the victims. The majority of burn incidents were suicidal (38.6%) in nature followed by accidental (37.3%) and homicidal (24.1%) deaths. The percentages of burns with a total body surface area (TBSA) over 50% were observed in most of the cases (82.5%). In most of the cases deaths occurred within a week (82%) and most of the victims died from septicaemia and pneumonia (43.7%) followed by neurogenic shock (28.5%). The results of this study provide the necessary information to implement programmes for health education relating to prevention of burns focusing on the domestic setting. PMID:23663899

    This study presents 5-year follow-up data on NG, a woman with adult onset myotonic dystrophy and progressive cognitive decline who was first described by Wilson et al. The extent of the cognitive impairment is atypical of symptom-onset in adulthood and of paternal inheritance, both of which apply to this case. Together, the present and earlier studies report the results of regular neuropsychological assessments over a 16-year period. Severe impairment in executive functioning, episodic and semantic memory were apparent early in the history, while visuospatial skills and working memory were only mildly impaired after 16 years of follow-up. There was also a progressive dyslexia, initially characterized by the regularization errors typical of surface dyslexia, but subsequently dominated by visual/phonological reading errors. This pattern of impairment is not typical of myotonic dystrophy but resembles semantic dementia. Whilst the deficits may be attributable wholly to myotonic dystrophy pathology, the co-existence of a form of semantic dementia is also possible. It is noted that the aggregation of tau protein is a neuropathological feature common to both diseases. PMID:16286337

    The effect of biochar application on soil friability and aggregate stability of loamy soil was studied at Brawijaya University field experimental station, Jatikerto, Malang, Indonesia. The soil has been planted with cassava for 4 years continuously and 1 year planted with maiz. The biochar applied was made from cassava stem and farm yard manure. It was found that biochar application, either made from cassava stem or farm yard manure improved soil qualities. Soil applied with biochar was more friable compared to that of the no biochar soil, although biochar application did not influence Atterberg limits. It seems that the higher friability of biochar applied soil was associated with the higher soil organic matter. It was found that until 5 years application, the biochar treated soil had a higher soil organic matter content. Soil applied with biochar possessed a better soil aggregate stability, both dry and wet stability. This was shown by the higher aggregate mean weight diameter (MWD) of biochar applied soil. The cassava biochar applied soil had MWD of 2.22 mm (dry stability) and 1.56 mm (wet stability), whereas the control soil had MWD of 1.45 mm (dry stability) and 1.25 (wet stability). There was a significant positive correlation between soil friability and dry aggregate stability. The biochar applied soils also had higher soil permeability.

    Fewer men than women with severe obesity undergo bariatric surgery for weight loss, and knowledge about men's situation after surgery, beyond medical status, is lacking. Our aim was to explore men's experiences with life after bariatric surgery from a long-term perspective. We conducted in-depth interviews with 13 men, aged 28–60 years, between 5 and 7 years after surgery. The analysis was inspired by Giorgi's phenomenological method. We found that agency was pivotal for how the men understood themselves and their lives after surgery. Weight loss meant regaining opportunities for living and acting in unrestricted and independent daily lives, yet surgery remained a radical treatment with complex consequences. Turning to surgery had involved conceptualizing their own body size as illness, which the men had resisted doing for years. After surgery, the rapid and major weight loss and the feelings of being exhausted, weak, and helpless were intertwined. The profound intensity of the weight loss process took the men by surprise. Embodying weight loss and change involved an inevitable renegotiating of experiences connected to the large body. Having bariatric surgery was a long-term process that seemed unfinished 5 years after surgery. Restrictions and insecurity connected to health and illness persist, despite successful weight loss and embodied change. Bariatric surgery initiated a complex and long-lasting life-changing process, involving both increased capacity for agency and illness-like experiences. PMID:26066518

    Although ganglion cysts of the anterior cruciate ligament have been described in the literature, they are a relatively rare phenomenon. Cyst formation after anterior cruciate ligament reconstruction is even less frequent, with only a few reported cases. The proposed etiology of these cysts has been attributed to a number of causes, including the use of bioabsorbable screws, Gore-Tex (W. L. Gore and Associates, Flagstaff, AZ) grafts, extra-articular fluid extravasation secondary to direct tibial tunnel communication, allografts with or without ethylene oxide sterilization, and the use of nonabsorbable suture. We report an unusual case of a recurrent pretibial ganglion cyst that initially formed more than 5 years after an anterior cruciate ligament reconstruction and recurred 2 years after resection of the mass. We believe the initial surgical resection was unsuccessful probably because the foreign body irritant was not identified. Only after resection of the entire stalk of the cyst and removal of all of the inciting suture material that was found near the entrance of the tibial tunnel were we able to definitively eradicate the ganglion cyst.

    Kolagani, Rajeswari

    It is a well-established fact that the scientific knowledge and skills acquired in the process of obtaining a degree in physics meet the needs of a variety of positions in multiple science and technology sectors. However, in addition to scientific competence, challenging careers often call for skills in advanced communication, leadership and team functions. The professional science master's degree, which has been nick-named as the `Science MBA', aims at providing science graduates an edge both in terms of employability and earning levels by imparting such skills. Our Professional Science Master's Program in Applied Physics is designed to develop these `plus' skills through multiple avenues. In addition to advanced courses in Applied Physics, the curriculum includes graduate courses in project management, business and technical writing, together with research and internship components. I will discuss our experience and lessons learned over the 5 years since the inception of the program in 2010.

    This work aimed to prospectively record all primary central nervous system tumor (PCNST) cases in France, for which histological diagnosis is available. The objectives were to (i) create a national registry and a network to perform epidemiological studies; (ii) implement clinical and basic research protocols; and (iii) harmonize the health care of patients affected by PCNST. For 5 years, 25 756 cases of newly diagnosed and histologically confirmed PCNST have been recorded. Histological diagnoses included glioma (48.9%), all other neuroepithelial tumors (5%), meningioma (28.8%), nerve sheath tumors (8.4%), lymphoma (3.2%) and others (5.7%). Cryopreservation was reported for 6018 PCNST specimens. Tumor resections (R) were performed in 78% cases, while biopsies accounted for 22%. Median age (MA), sex, percentage R and number of cryopreserved tumors were detailed for each histology; for example, out of 6053 glioblastomas (MA 63 years, male 59.4%, R 62%, 1611 were cryopreserved), and out of 37 atypical teratoid/rhabdoid tumors (MA 2 years, male 56.8%, R 94%, 17 were cryopreserved). This database or databank dedicated to PCNST cases contains detailed data on clinical, histological and other characteristics, such as the inclusion of data on cryopreserved specimens that are not available in other European registries. Therefore, this is a valuable resource that can be used for planning future epidemiological and clinical research. PMID:21554472

    This issue of the Archives of Physical Medicine and Rehabilitation is dedicated to current research findings of the Model Spinal Cord Injury Systems (MSCIS) program. The MSCIS grants were established by the Rehabilitation Services Administration in the 1970s. Now administered by the National Institute on Disability and Rehabilitation Research within the Office of Special Education and Rehabilitation Services in the US Department of Education, the program has included 27 spinal cord injury centers in the United States over the years. In the current 5-year grant cycle (2000-2005), there are 16 designated regional MSCIS centers. In addition to establishing a comprehensive system of care, the grantees contribute patient data to the National Spinal Cord Injury Database (which now contains data on 30,532 subjects with follow-up of up to 30 y). In addition, the MSCIS grants enable the conduct of site-specific and collaborative research projects. To highlight the research findings of the program, the MSCIS have produced a special dissemination effort during each of the previous 5 grant cycles, with this issue of the Archives representing the latest of these endeavors. This article provides a brief history of the MSCIS program and highlights the important findings of the 17 original research articles contained in this issue. PMID:15520967

    Diabetic mastopathy is a recently described collection of radiographical and histological features found in dense fibrous masses of the breast in long standing Type I diabetes. We describe the first case of bilateral disease with the alternate progression and regression of the disease over a 5 year period. A 45-year-old woman has been affected of insulin dependent diabetes mellitus (IDDM) for 21 years. She developed palpable mass retromamillar of the right side, indistinguishable radiographically from cancer. The histology showed a diabetic mastopathy (DMP) with B-lymphocytic ductitis and lobulitis, a discrete monocellular vasculitis and a keloid-like fibrosis. After 22 months she developed a suspicious palpable mass contralateral on the left side. The FNAB presented an identical morphology on histology. Additionally 10 months later there were no palpable masses of both mammae. Mammographically no suspect alterations were observed. One year later the clinical and mammographical examination showed similar findings, mentioned before. The pathogenesis is still obscure and includes the hypothesis of extracellular accumulation, secondary to prolonged hyperglycemia in IDDM, production of alternated non-enzymatic glycosylated end products with neoantigen formation, B cell predominant inflammation with autoimmune response against neoantigens and cytokine release secondary to the autoimmune response.

    Executive function (EF) refers to a set of higher order cognitive processes that control and modulate cognition under continuously changing and multiple task demands. EF plays a central role in early childhood, is associated and predictive of important cognitive achievements and has been recognized as a significant aspect of school readiness. This study examines the efficacy of a group based intervention for 5-year-old children that focuses on basic components of EF (working memory, inhibitory control, cognitive flexibility). The intervention included 12 sessions, lasted 1 month and used low-cost materials. Seventy-five children took part in the study. The results indicate that the children who attended the intervention outperformed controls in simple and more complex EF tasks. Specifically, these children exhibited increased abilities to delay gratification, to control on-going responses, to process and update information, and to manage high cognitive conflict. These results suggest the possibility that this intervention, which may be easily implemented in educational services, can promote EF during preschool period before the entrance in primary school.

    Veliger larvae of the NE Pacific snail Fusitriton oregonensis were reared in culture for 4.5 to 4.6 years from hatching to metamorphosis and through postlarval growth to reproduction. Larval shells grew in length from 0.20 to 3.9 mm. Late veligers grew slowly, but shell sizes increased even in the 4th and 5th years. Widths of larval shells at late stages equaled or exceeded those of the protoconchs of two juveniles from the field. Cultured larvae did not metamorphose until presented with subtidal rocks and associated biota. There was no indication of larval senescence: the first 2 years of postmetamorphic shell growth were slightly faster, and time from metamorphosis to first reproduction (3.3 years) was slightly less than for an individual that had developed to metamorphic competence in the plankton. A 4.5-year larval phase exceeds previous estimates for teleplanic larval durations and greatly exceeds estimates of the time for transport across oceans. This extraordinarily long larval period may exceed the usual duration in nature but shows that larval periods can be much longer than previously suspected without complete stasis in growth and with little if any loss of viability.

    The aims of this prospective school cohort study were to describe the epidemiology of diagnosed back pain in childhood, classified as either nontraumatic or traumatic back injury, and to estimate the association with physical activity in different settings. Over 2.5 years, 1240 children aged 6-12 years were surveyed weekly using mobile text messages to ask about the presence or absence of back pain. Pain was clinically diagnosed and injuries were classified using the International Classification of Diseases version 10. Physical activity data were obtained from text messages and accelerometers. Of the 315 back injuries diagnosed, 186 injuries were nontraumatic and 129 were traumatic. The incidence rate ratio was 1.5 for a nontraumatic back injury compared with a traumatic injury. The overall estimated back injury incidence rate was 0.20 per 1000 physical activity units (95% confidence interval 0.18-0.23). The back injury incidence rates were higher for sports when exposure per 1000 physical activity units was taken into consideration and especially children horse-riding had a 40 times higher risk of sustaining a traumatic back injury compared to the risk during non-organized leisure time physical activity. However, the reasonably low injury incidence rates support the recommendations of children continuously being physically active. PMID:26130046

    OBJECTIVE: To reconstruct and analyse mortality trends in children younger than 5 years in sub-Saharan Africa between 1950 and 2000. METHODS: We selected 66 Demographic and Health Surveys and World Fertility Surveys from 32 African countries for analysis. Death rates were calculated by yearly periods for each survey. When several surveys were available for the same country, overlapping years were combined. Country-specific time series were analysed to identify periods of monotonic trends, whether declining, steady or increasing. We tested changes in trends using a linear logistic model. FINDINGS: A quarter of the countries studied had monotonic declining mortality trends: i.e. a smooth health transition. Another quarter had long-term declines with some minor rises over short periods of time. Eight countries had periods of major increases in mortality due to political or economic crises, and in seven countries mortality stopped declining for several years. In eight other countries mortality has risen in recent years as a result of paediatric AIDS. Reconstructed levels and trends were compared with other estimates made by international organizations, usually based on indirect methods. CONCLUSION: Overall, major progress in child survival was achieved in sub-Saharan Africa during the second half of the twentieth century. However, transition has occurred more slowly than expected, with an average decline of 1.8% per year. Additionally, transition was chaotic in many countries. The main causes of mortality increase were political instability, serious economic downturns, and emerging diseases. PMID:16799731

    There is a strong need for non-invasive detection of human atherosclerotic lesions. One of the radioisotopic approaches using Indium-111-HIG has been shown to accumulate in oxidized LDL-rich foam cells and inflammatory vascular lesions. Earlier human studies in 200 patients, 100 with peripheral vascular disease and 100 with carotid artery disease comparing In-111-HIG scintigraphy with sonographic data revealed a high sensitivity (70%-77%) but a very low specificity (33%-41%). At this time we concluded the approach "not promising" for human studies. However, clinical follow-up over 5 years now shows that those patients with positive In-111-HIG scintigraphy exhibited a significantly higher vascular morbidity (P<0,01) and mortality (P<0,01), especially in the immediate follow-up period. Retrospective analysis discovered higher CRP and isoprostane (8-epi-prostaglandin (PG) F2α) levels in HIG-positive patients at the time of scintigraphy. These findings indicate that In-111-HIG reflecting vascular lesions with a high inflammatory component, probably more prone to rupture, may identify a population at high vascular risk rather than a lesion at risk. The clinical impact of this finding should be assessed in prospective studies. PMID:26665225

    The Student Response System is a commercially available electronic communication system applicable to many teaching and testing situations. At rather short intervals during a programmed course, the instructor projects on a screen multiple-choice questions that the student should have learned to answer during one or two previous teaching steps. Correct and incorrect responses are indicated on a panel on the desk of the instructor. If students fail to give the correct answer, the teaching step is repeated. Recurrent incorrect answers indicate that explanations had been inappropriate or that test slides were poorly designed. Thus, the system allows the instructor to monitor his own performance. Students are kept alert and attention spans are prolonged; communication is increased and personal embarrassment is minimized. Only the instructor has access to the individual student's response. Most learning takes place in the classroom rather than during subsequent private study. This system is quite versatile and offers potential uses hitherto untested in medical education at all levels.

    The aim of our study was to test the hypothesis that two systems are involved in verbal working memory; one is specifically dedicated to the maintenance of phonological representations through verbal rehearsal while the other would maintain multimodal representations through attentional refreshing. This theoretical framework predicts that phonologically related phenomena such as the phonological similarity effect (PSE) should occur when the domain-specific system is involved in maintenance, but should disappear when concurrent articulation hinders its use. Impeding maintenance in the domain-general system by a concurrent attentional demand should impair recall performance without affecting PSE. In three experiments, we manipulated the concurrent articulation and the attentional demand induced by the processing component of complex span tasks in which participants had to maintain lists of either similar or dissimilar words. Confirming our predictions, PSE affected recall performance in complex span tasks. Although both the attentional demand and the articulatory requirement of the concurrent task impaired recall, only the induction of an articulatory suppression during maintenance made the PSE disappear. These results suggest a duality in the systems devoted to verbal maintenance in the short term, constraining models of working memory. PMID:23419012

    Aging is characterized by widespread degenerative changes in tissue morphology and function and an increase in the incidence of human diseases such as cancer, stroke, and Alzheimer disease. Findings from recent genetic studies suggest that molecular mechanisms that influence life span are evolutionarily conserved, and interventions that extend the life span of model organisms such as worms and flies are likely to have similar effects on vertebrates such as humans. However, little progress has been made in identifying drugs that delay aging. We identified 3 pharmacologic compounds, ethosuximide, trimethadione, and 3,3-diethyl-2-pyrrolidinone, that extend lifespan and delay age-related degenerative changes in the nematode worm Caenorhabditis elegans. All 3 compounds are anticonvulsants that modulate neural activity in vertebrates, and ethosuximide and trimethadione are used to treat absence seizures in humans. We discuss existing evidence that these drugs might also delay vertebrate aging and suggest experiments that could test this hypothesis. Genetic and cell ablation studies conducted with model organisms have demonstrated connections between the nervous system and aging. Our studies provide additional support for the hypothesis that neural activity plays a role in lifespan determination, since ethosuximide and trimethadione regulated neuromuscular activity in nematodes. Our findings suggest that the lifespan extending activity of these compounds is related to the anticonvulsant activity, implicating neural activity in the regulation of aging. We also discuss models that explain how the nervous system influences lifespan. PMID:16606760

    The burden of late-effects for young onset brain tumor (BT) survivors needs more careful evaluation. Our aim was to assess the need for endocrinological and neurological medication among this specific group. We identified 5-year survivors diagnosed at the age of 0-24 years between 1988 and 2004 from the Finnish Cancer Registry (N = 602). Data on endocrinological and neurological drug purchases were collected from the Social Insurance Institution of Finland. Five years after diagnosis the most commonly purchased drugs had been: antiepileptics (44.8 %), systemic hydrocortisone (18.3 %), female sex hormones (17.6 %), thyroid hormones (11.2 %), and growth hormone (10.0 %). The survivors showed an increased hazard ratio (HR) for a need for new types of drugs still 5 years after diagnosis. Thyroid hormones (HR 10.6, 95 % CI 5.1-21.4), estrogens (HR 8.0, 95 % CI 2.1-25.7), and antiepileptics (HR 6.3, 95 % CI 3.4-11.2) were bought with high frequencies. Irradiation increased the hazard for drug-purchases other than antiepileptics. Cumulative incidence of purchases of estrogens or androgens increased still 15 years after diagnosis. The cumulative incidence of purchasing thyroid hormones and antiepileptics showed continuous increase for the youngest group, whereas survivors diagnosed at 15-24 years of age reached stable level before 15 years from diagnosis. The need for new medication continued more than a decade after BT diagnosis. Especially the need for new thyroid or sex hormone medication among childhood BT survivors may emerge long after diagnosis. PMID:27115743

    Objectives To investigate the association between the trends of CT utilisation in an emergency department (ED) and changes in clinical imaging practice and patients' disposition. Setting A hospital-based retrospective observational study of a public 1520-bed referral medical centre in Taiwan. Participants Adult ED visits (aged ≥18 years) during 2009–2013, with or without receiving CT, were enrolled as the study participants. Main outcome measures For all enrolled ED visits, we retrospectively analysed: (1) demographic characteristics, (2) triage categories, (3) whether CT was performed and the type of CT scan, (4) further ED disposition, (5) ED cost and (6) ED length of stay. Results In all, 269 239 adult ED visits (148 613 male patients and 120 626 female patients) were collected during the 5-year study period, comprising 38 609 CT scans. CT utilisation increased from 11.10% in 2009 to 17.70% in 2013 (trend test, p<0.001). Four in 5 types of CT scan (head, chest, abdomen and miscellaneous) were increasingly utilised during the study period. Also, CT was increasingly ordered annually in all age groups. Although ED CT utilisation rates increased markedly, the annual ED visits did not actually increase. Moreover, the subsequent admission rate, after receiving ED CT, declined (59.9% in 2009 to 48.2% in 2013). Conclusions ED CT utilisation rates increased significantly during 2009–2013. Emergency physicians may be using CT for non-emergent studies in the ED. Further investigation is needed to determine whether increasing CT utilisation is efficient and cost-effective. PMID:27279477

    Prolongation of ventricular repolarization, which is represented by QTc prolongation on the standard ECG can be considered as increased risk for fatal arrhythmia. However, in pacemaker dependency (with ventricular pacing from the right apex) Ventricular Pacemaker causes abnormal steps of ventricular activation and therefore widens QRS complex and alters ventricular repolarization. It is still questionable whether QTc prolongation in right ventricular-paced patients is associated with increased risk of fatal arrhythmia or other cardiac complications. The other important question is whether the pacemaker dependent patient with long QTc interval may safely receive medications with known potential to prolong ventricular repolarization. The aim of the study was to determine whether QTc prolongation in VP (ventricular pacemaker) patients is associated with increased risk of fatal arrhythmia or other cardiac complications and whether these patients can safely receive medications with known potential to prolong ventricular repolarization. The study is based on retrospective analysis of the QTc interval prior and after pacemaker insertion; dynamic changes of QTc interval and possible influence of the medications, with known potential to prolong ventricular repolarization. Study population consisted 76 patients with narrow native QRS complexes and QTcF/QTcB <500 ms for both male and female patients. QTc prolongation in VP patients most likely does not represent true repolarization abnormalities and is not associated with risk of fatal arrhythmia. While analysis of group receiving medications with known potency of QTc increase we found no additional tendency of QTc increase. Based on our data receiving the medications with known potency of QTc prolongation in VP patients should be considered as safe approach. Long-term follow up data (5 years) assessed retrospectively shows that in patients with widened QRS after VP are at increased risk of development of HF and HF

    BACKGROUND: Acetaminophen is a drug widely used in children because of its safety and efficacy. Although the risk of its toxicity is lower in children such reactions occur in pediatric patients from intentional overdoses and less frequently attributable to unintended inappropriate dosing. The aim of reporting this case is to attract the attention to the risk of the acetaminophen toxicity when administered in high doses. CASE PRESENTATION: We report here a 5 year old girl who developed fulminate liver failure with renal impairment and acute pancreatitis, as a result of acetaminophen toxicity caused from unintentional repeated supratherapeutic ingestion, with a total administered dose of 4800 mg in three consecutive days, 1600 mg/day, approximately 90 mg/kg/day. The blood level of acetaminophen after 10 hours of the last administered dose was 32 mg/l. The patient presented with high fever, jaundice, lethargic, agitating with abdominal pain accompanied by encephalopathy. The liver function test revealed with high level of alanine aminotransferase 5794 UI/l and aspartate aminotransferase 6000 UI/l. Early initiation of oral N-acetylcysteine (NAC) after biochemical evidence of liver toxicity was beneficial with rapid improvement of liver enzymes, hepatic function and encephalopathy. During the course of the illness the child developed acute pancreatitis with hyperamylasemia 255 UI/L and hyperlypasemia 514 UI/L. Patient totally recovered within 29 days. CONCLUSION: Healthcare providers should considered probable acetaminophen toxicity in any child who has received the drug and presented with liver failure. When there is a high index of suspicion of acetaminophen toxicity NAC should be initiated and continued until there are no signs of hepatic dysfunction.

    Since 2008, the World Health Organization (WHO) has coordinated the Global Rotavirus Surveillance Network, a network of sentinel surveillance hospitals and laboratories that report to ministries of health (MoHs) and WHO clinical features and rotavirus testing data for children aged <5 years hospitalized with acute gastroenteritis. In 2013, WHO conducted a strategic review to assess surveillance network performance, provide recommendations for strengthening the network, and assess the network's utility as a platform for other vaccine-preventable disease surveillance. The strategic review team determined that during 2011 and 2012, a total of 79 sites in 37 countries met reporting and testing inclusion criteria for data analysis. Of the 37 countries with sites meeting inclusion criteria, 13 (35%) had introduced rotavirus vaccine nationwide. All 79 sites included in the analysis were meeting 2008 network objectives of documenting presence of disease and describing disease epidemiology, and all countries were using the rotavirus surveillance data for vaccine introduction decisions, disease burden estimates, and advocacy; countries were in the process of assessing the use of this surveillance platform for other vaccine-preventable diseases. However, the review also indicated that the network would benefit from enhanced management, standardized data formats, linkage of clinical data with laboratory data, and additional resources to support network functions. In November 2013, WHO's Strategic Advisory Group of Experts on Immunization (SAGE) endorsed the findings and recommendations made by the review team and noted potential opportunities for using the network as a platform for other vaccine-preventable disease surveillance. WHO will work to implement the recommendations to improve the network's functions and to provide higher quality surveillance data for use in decisions related to vaccine introduction and vaccination program sustainability.

    Previously, a small study showed that 14f was the predominant subtype of Treponema pallidum in Shanghai, China. The result was quite different from the genotype distribution in other areas of China. This study aimed to identify the strain types of Treponema pallidum in samples collected over a 5-year period in Shanghai. From 2007 to 2011, genital swabs were collected from patients with syphilis from the Shanghai Skin Disease Hospital. Positive specimens were typed by the enhanced typing method by adding a tp0548 gene to the existing arp and tpr genotype system. In total, 304 of the 372 enrolled patients yielded fully typeable DNA. Ten arp types (4, 6, 8, 9, 11, 12, 13, 14, 15, and 19), 3 tpr types (a, d, and o), and 5 tp0548 types (a, c, f, g, and i) were identified. In total, 12 subtypes were identified with a combination of the arp and tpr genes. Subtype 14d was found in 270 samples (88.8%). When the combination included the tp0548 gene, the 12 CDC subtypes identified were divided into 14 strain types. The predominant type was 14d/f (88.8%), followed by 15d/f (3.6%), 13d/f (1.3%), and 19d/c (1.3%). Two of the 44 14d/f-infected patients and both of the 19d/c-infected patients who underwent a lumbar puncture were diagnosed with neurosyphilis. This study showed that the predominant type in Shanghai was 14d/f. While this is in keeping with data from other areas in China, it is different from an earlier report showing that 14f is the most common genotype in Shanghai. Further studies are needed to better understand the association between strain types and neurosyphilis. PMID:22972832

    Background Collaborations for global surgery face many challenges to achieve fair and safe patient care and to build sustainable capacity. The 2004 terrorist attack on a school in Beslan in North Ossetia in the Russian North Caucasus left many victims with complex otologic barotrauma. In response, we implemented a global surgery partnership between the Vladikavkaz Children's Hospital, international surgical teams, the North Ossetian Health Ministry, and civil society organizations. This study's aim was to describe the implementation and 5-year results of capacity building for complex surgery in a postconflict, mid-income setting. Design We conducted an observational study at the Children's Hospital in Vladikavkaz in the autonomous Republic of North Ossetia-Alania, part of the Russian Federation. We assessed the outcomes of 15 initial patients who received otologic surgeries for complex barotrauma resulting from the Beslan terrorism attack and for other indications, and report the incidence of intra- and postoperative complications. Results Patients were treated for trauma related to terrorism (53%) and for indications not related to violence (47%). None of the patients developed peri- or postoperative complications. Three patients (two victims of terrorism) who underwent repair of tympanic perforations presented with re-perforations. Four junior and senior surgeons were trained on-site and in Germany to perform and teach similar procedures autonomously. Conclusions In mid-income, postconflict settings, complex surgery can be safely implemented and achieve patient outcomes comparable to global standards. Capacity building can build on existing resources, such as operation room management, nursing, and anesthesia services. In postconflict environments, substantial surgical burden is not directly attributable to conflict-related injury and disease, but to health systems weakened by conflicts.

    Outcomes of the first 60 noncemented Omnifit-HA total hip arthroplasties in 56 patients were studied prospectively for 2 to 5 years. The femoral prosthesis had a proximal third circumferential hydroxyapatite coated surface treatment. The acetabular component was a hemispheric modular, porous, nonhydroxyapatite press fit cup, supplemented with screw fixation. One cup was revised for recurrent dislocation, with no femoral revisions. The mean Harris hip score was 54 (range, 20-76) before surgery and 96 (range, 83-100) at final followup, with all patients having an excellent or good outcome. Mild thigh pain occurred in 6% of hips. Subsidence occurred in 9% of hips (range, 1-2.8 mm); in all cases, subsidence was nonprogressive after 1 year. Stable bone ingrowth fixation was evident at the hydroxyapatite coated portion in 100%. A sclerotic reactive line adjacent to the nonhydroxyapatite portion of the stem occurred in 81% but was not adjacent to the hydroxyapatite coated portion of any stem. Endosteal condensation occurred in 90% and correlated with a higher Harris hip score (mean score, 96 with, 91 without). Endosteal lysis adjacent to or distal to the hydroxyapatite coating did not occur. Lytic lesions at the calcar occurred in 19% and correlated with a greater linear acetabular polyethylene wear rate (mean, 0.30 mm/year with lytic lesions, 0.17 mm/year without). This noncemented stem with proximal third hydroxyapatite coating showed excellent short term clinical and radiographic outcome. Absence of distal endosteal lysis, along with correlation of calcar erosion to polyethylene wear, suggests that early circumferential bony ingrowth afforded by hydroxyapatite coating prevents distal endosteal access to polyethylene debris at short term followup.

    Background The sole focus of models of insight on bio-medical perspectives to the complete exclusion of local, non-medical and cultural constructs mandates review. This study attempted to investigate the impact of insight, psychopathology, explanatory models of illness on outcome of first episode schizophrenia. Method Patients diagnosed to have DSM IV schizophrenia (n = 131) were assessed prospectively for insight, psychopathology, explanatory models of illness at baseline, 6, 12 and 60 months using standard instruments. Multiple linear and logistic regression and generalized estimating equations (GEE) were employed to assess predictors of outcome. Results We could follow up 95 (72.5%) patients. Sixty-five of these patients (68.4%) achieved remission. There was a negative relationship between psychosis rating and insight scores. Urban residence, fluctuating course of the initial illness, and improvement in global functioning at 6 months and lower psychosis rating at 12 months were significantly related to remission at 5 years. Insight scores, number of non-medical explanatory models and individual explanatory models held during the later course of the illness were significantly associated with outcome. Analysis of longitudinal data using GEE showed that women, rural residence, insight scores and number of non-medical explanatory models of illness held were significantly associated with BPRS scores during the study period. Conclusions Insight, the disease model and the number of non-medical model positively correlated with improvement in psychosis arguing for a complex interaction between the culture, context and illness variables. These finding argue that insight and explanatory models are secondary to psychopathology, course and outcome of the illness. The awareness of mental illness is a narrative act in which people make personal sense of the many challenges they face. The course and outcome of the illness, cultural context, acceptable cultural explanations

    Introduction: There is a gradual increasing trend in childhood cancers in India and pediatric palliative care in India is an emerging specialty. Prescribing pain and symptom control drugs in children with cancer requires knowledge of palliative care formulary, dosing schedules, and prescription guidelines. This study is a retrospective audit of prescribing practices of a specialist palliative care service situated in a tertiary cancer center. Methods: A total of 1135 medication records of children receiving specialist pediatric palliative care services were audited for 5 years (2010–2014) to evaluate prescribing practices in children with advanced cancer. Results: A total of 51 types of drugs were prescribed with an average of 4.2 drugs per prescription. 66.9% of the prescriptions had paracetamol, and 33.9% of the prescriptions had morphine. Most common nonsteroidal anti-inflammatory drugs prescribed was ibuprofen (23.9%), and more than 50% of the prescriptions had aperients. The most commonly prescribed aperient was a combination of liquid paraffin and sodium-picosulfate. Dexamethasone was prescribed in 51.9% of patients and in most cases this was part of oral chemotherapy regimen. Generic names in prescription were used only in 33% of cases, and adverse effects of the drugs were documented in only 9% of cases. In 25% of cases, noncompliance to the WHO prescription guidelines was seen, and patient compliance to prescription was seen in 40% of cases. Conclusions: Audit of the prescribing practices in specialist pediatric palliative care service shows that knowledge of pediatric palliative care formulary, rational drug use, dosing, and prescribing guidelines is essential for symptom control in children with advanced life-limiting illness. Noncompliance to WHO prescribing guidelines in one fourth of cases and using nongeneric names in two-thirds of prescription indicates poor prescribing practices and warrants prescriber education.

    To empower governments to formulate rational policies without pressure from any group, and to increase the use of evidence-based decision-making to adapt global recommendations on immunization to their local context, the WHO has recommended on multiple occasions that countries should establish National Immunization Technical Advisory Groups (NITAGs). The World Health Assembly (WHA) reinforced those recommendations in 2012 when Member States endorsed the Decade of Vaccines Global Vaccine Action Plan (GVAP). NITAGs are multidisciplinary groups of national experts responsible for providing independent, evidence-informed advice to health authorities on all policy-related issues for all vaccines across all populations. In 2012, according to the WHO-UNICEF Joint Reporting Form, among 57 countries eligible for immunization program financial support from the GAVI Alliance, only 9 reported having a functional NITAG. Since 2008, the Supporting Independent Immunization and Vaccine Advisory Committees (SIVAC) Initiative (at the Agence de Médecine Préventive or AMP) in close collaboration with the WHO and other partners has been working to accelerate and systematize the establishment of NITAGs in low- and middle-income countries. In addition to providing direct support to countries to establish advisory groups, the initiative also supports existing NITAGs to strengthen their capacity in the use of evidence-based processes for decision-making aligned with international standards. After 5 years of implementation and based on lessons learned, we recommend that future efforts should target both expanding new NITAGs and strengthening existing NITAGs in individual countries, along three strategic lines: (i) reinforce NITAG institutional integration to promote sustainability and credibility, (ii) build technical capacity within NITAG secretariats and evaluate NITAG performance, and (iii) increase networking and regional collaborations. These should be done through the development

    Background Uremic pruritus is a common and intractable symptom in patients on chronic hemodialysis, but factors associated with the severity of pruritus remain unclear. This study aimed to explore the associations of metabolic factors and dialysis adequacy with the aggravation of pruritus. Methods We conducted a 5-year prospective cohort study on patients with maintenance hemodialysis. A visual analogue scale (VAS) was used to assess the intensity of pruritus. Patient demographic and clinical characteristics, laboratory parameters, dialysis adequacy (assessed by Kt/V), and pruritus intensity were recorded at baseline and follow-up. Change score analysis of the difference score of VAS between baseline and follow-up was performed using multiple linear regression models. The optimal threshold of Kt/V, which is associated with the aggravation of uremic pruritus, was determined by generalized additive models and receiver operating characteristic analysis. Results A total of 111 patients completed the study. Linear regression analysis showed that lower Kt/V and use of low-flux dialyzer were significantly associated with the aggravation of pruritus after adjusting for the baseline pruritus intensity and a variety of confounding factors. The optimal threshold value of Kt/V for pruritus was 1.5 suggested by both generalized additive models and receiver operating characteristic analysis. Conclusions Hemodialysis with the target of Kt/V ≥1.5 and use of high-flux dialyzer may reduce the intensity of pruritus in patients on chronic hemodialysis. Further clinical trials are required to determine the optimal dialysis dose and regimen for uremic pruritus. PMID:23940749

    Purpose Currently, insufficient data exist to evaluate the relationship between angiographic late loss (LL) and long-term clinical outcome after drug-eluting stent (DES) implantation. In this study, we hypothesized that angiographic LL between 0.3 and 0.6 mm correlate with favorable long-term clinical outcomes. Materials and Methods Patients were enrolled in the present study if they had undergone both DES implantation in single coronary vessel and a subsequent follow-up angiogram (n=634). These individuals were then subdivided into three groups based on their relative angiographic LL: group I (angiographic LL <0.3 mm, n=378), group II (angiographic LL between 0.3 and 0.6 mm, n=124), and group III (angiographic LL >0.6 mm, n=134). During a 5-year follow-up period, all subjects were tracked for critical events, defined as any cause of death or myocardial infarction, which were then compared among the three groups. Results Mean follow-up duration was 63.0±10.0 months. Critical events occurred in 25 subjects in group I (6.6%), 5 in group II (4.0%), and 17 in group III (12.7%), (p=0.020; group I vs. group II, p=0.293; group II vs. group III, p=0.013). In a subsequent multivariate logistic regression analysis, chronic renal failure [odds ratio (OR)=3.29, 95% confidence interval (CI): 1.48-7.31, p=0.003] and long lesion length, defined as lesion length >28 mm (OR=1.88, 95% CI: 1.02-3.46, p=0.042) were independent predictors of long-term critical events. Conclusion This retrospective analysis fails to demonstrate that post-DES implantation angiographic LL between 0.3 and 0.6 mm is protective against future critical events. PMID:23225797

    Background Common diseases, particularly dementia, entail large social costs, previously well described for the U.S. population. Less is known about end-of-life costs of specific diseases and the associated financial risk for individual households. Objective To examine social costs and financial risks faced by Medicare beneficiaries five years before death. Design Retrospective cohort. Setting Health and Retirement Study. Participants Medicare fee-for-service beneficiaries, aged 70 years or older, who died 2005-2010 (N = 1702), stratified into four cohorts: individuals with high probability of dementia, or with either heart disease, cancer, or other causes of death. Measurements Total social costs and its components: Medicare, Medicaid, private insurance, out-of-pocket, and informal care, measured over the last 5 years of life; and out-of-pocket spending as a proportion of household wealth. Results Average total cost per decedent for dementia ($287,038) was significantly greater than for those who died of heart disease ($175,136), cancer ($173,383), or other causes ($197,286), p<0.001. While Medicare expenditures were similar across groups, average out-of-pocket spending for dementia patients ($61,522) was 81% higher than for non-dementia patients ($34,068); a similar pattern held for informal care. Out-of-pocket spending for the dementia group (median, $36,919) represented 32% of wealth measured five years before death, compared to 11% for non-dementia decedents (p<0.001). This proportion was greater for Blacks (84%), those with less than high school education (48%), and unmarried/widowed women (58%). Limitations Imputed Medicaid, private insurance and informal care costs Conclusions Healthcare expenditures among those with dementia were substantially larger than for other diseases, with much of those expenses uninsured, thus placing a large financial burden on families. These burdens are particularly pronounced among demographic groups least prepared for

    2010-01-01

    Objective To determine whether endothelial cell loss 5 years after successful corneal transplantation is related to the age of the donor. Design Multicenter, prospective, double-masked clinical trial. Participants Three hundred forty-seven subjects participating in the Cornea Donor Study who had not experienced graft failure 5 years after corneal transplantation for a moderate-risk condition (principally Fuchs’ dystrophy or pseudophakic corneal edema). Testing Specular microscopic images of donor corneas obtained before surgery and postoperatively at 6 months, 12 months, and then annually through 5 years were submitted to a central reading center to measure endothelial cell density (ECD). Main Outcome Measure Endothelial cell density at 5 years. Results At 5 years, there was a substantial decrease in ECD from baseline for all donor ages. Subjects who received a cornea from a donor 12 to 65 years old experienced a median cell loss of 69% in the study eye, resulting in a 5-year median ECD of 824 cells/mm2 (interquartile range, 613–1342), whereas subjects who received a cornea from a donor 66 to 75 years old experienced a cell loss of 75%, resulting in a median 5-year ECD of 654 cells/mm2 (interquartile range, 538–986) (P [adjusted for baseline ECD] = 0.04). Statistically, there was a weak negative association between ECD and donor age analyzed as a continuous variable (r [adjusted for baseline ECD] = −0.19; 95% confidence interval, −0.29 to −0.08). Conclusions Endothelial cell loss is substantial in the 5 years after corneal transplantation. There is a slight association between cell loss and donor age. This finding emphasizes the importance of longer-term follow-up of this cohort to determine if this relationship affects graft survival. PMID:18387408

    Adults' expertise in face recognition has been attributed to norm-based coding. Moreover, adults possess separable norms for a variety of face categories (e.g., race, sex, age) that appear to enhance recognition by reducing redundancy in the information shared by faces and ensuring that only relevant dimensions are used to encode faces from a given category. Although 5-year-old children process own-race faces using norm-based coding, little is known about the organization and refinement of their face space. The current study investigated whether 5-year-olds rely on category-specific norms and whether experience facilitates the development of dissociable face prototypes. In Experiment 1, we examined whether Chinese 5-year-olds show race-contingent opposing aftereffects and the extent to which aftereffects transfer across face race among Caucasian and Chinese 5-year-olds. Both participant races showed partial transfer of aftereffects across face race; however, there was no evidence for race-contingent opposing aftereffects. To examine whether experience facilitates the development of category-specific prototypes, we investigated whether race-contingent aftereffects are present among Caucasian 5-year-olds with abundant exposure to Chinese faces (Experiment 2) and then tested separate groups of 5-year-olds with two other categories with which they have considerable experience: sex (male/female faces) and age (adult/child faces) (Experiment 3). Across all three categories, 5-year-olds showed no category-contingent opposing aftereffects. These results demonstrate that 5 years of age is a stage characterized by minimal separation in the norms and associated coding dimensions used for faces from different categories and suggest that refinement of the mechanisms that underlie expert face processing occurs throughout childhood.

    AIM: To determine predictors of long term survival after resection of hilar cholangiocarcinoma (HC) by comparing patients surviving > 5 years with those who survived < 5 years. METHODS: This is a retrospective study of patients with pathologically proven HC who underwent surgical resection at the Gastroenterology Surgical Center, Mansoura University, Egypt between January 2002 and April 2013. All data of the patients were collected from the medical records. Patients were divided into two groups according to their survival: Patients surviving less than 5 years and those who survived > 5 years. RESULTS: There were 34 (14%) long term survivors (5 year survivors) among the 243 patients. Five-year survivors were younger at diagnosis than those surviving less than 5 years (mean age, 50.47 ± 4.45 vs 54.59 ± 4.98, P = 0.001). Gender, clinical presentation, preoperative drainage, preoperative serum bilirubin, albumin and serum glutamic-pyruvic transaminase were similar between the two groups. The level of CA 19-9 was significantly higher in patients surviving < 5 years (395.71 ± 31.43 vs 254.06 ± 42.19, P = 0.0001). Univariate analysis demonstrated nine variables to be significantly associated with survival > 5 year, including young age (P = 0.001), serum CA19-9 (P = 0.0001), non-cirrhotic liver (P = 0.02), major hepatic resection (P = 0.001), caudate lobe resection (P = 0.006), well differentiated tumour (P = 0.03), lymph node status (0.008), R0 resection margin (P = 0.0001) and early postoperative liver cell failure (P = 0.02). CONCLUSION: Liver status, resection of caudate lobe, lymph node status, R0 resection and CA19-9 were demonstrated to be independent risk factors for long term survival. PMID:27358676

    Adverse effects of long-term usage of triclosan-containing toothpaste in humans are currently unknown. We assessed the effect of long-term use of 0.3% triclosan-toothpaste on serious adverse events (SAEs) in patients with cardiovascular disease (CVD). 438 patients with a history of stable CVD were entered into the 5-year longitudinal Cardiovascular and Periodontal Study at Prince Charles Hospital, Brisbane, Australia and randomised into test (triclosan) or placebo groups. There were no significant differences in demographics or clinical features between the groups. Patients were examined at baseline, and annually for 5-years. SAEs were classified according to the System Organ Classes defined by MedDRA (Medical Dictionary for Regulatory Activities). Results were analysed using chi square and Kaplan Meier analysis. Overall, 232 patients (123 in the triclosan group; 109 in the placebo group) experienced 569 SAEs (288 in the triclosan group and 281 in the placebo group). There was no significant difference between the groups in numbers of patients experiencing SAEs (p=0.35) or specific cardiovascular SAEs (p=0.82), nor in time to the first SAE or first cardiovascular SAE, irrespective of gender, age or BMI after adjusting for multiple comparisons (p>0.05). The adjusted odds of experiencing an SAE were estimated to increase by 2.7% for each year of age (p=0.02) and the adjusted odds of experiencing a cardiovascular SAE were estimated to increase by 5.1% for each unit increase in BMI (p=0.02). Most cardiovascular events were related to unstable angina or myocardial infarcts, 21 were associated with arrhythmia and 41 were vascular events such as aortic aneurysm and cerebrovascular accident. Within the limitations of the present study the data suggest that the use of triclosan-toothpaste may not be associated with any increase in SAEs in this CVD population. The long-term impact of triclosan on hormone-related disease, such as cancer, in humans remains to be determined

    Purpose: To determine the prevalence of valvular abnormalities after radiation therapy involving the heart region and/or treatment with anthracyclines and to identify associated risk factors in a large cohort of 5-year childhood cancer survivors (CCS). Methods and Materials: The study cohort consisted of all 626 eligible 5-year CCS diagnosed with childhood cancer in the Emma Children's Hospital/Academic Medical Center between 1966 and 1996 and treated with radiation therapy involving the heart region and/or anthracyclines. We determined the presence of valvular abnormalities according to echocardiograms. Physical radiation dose was converted into the equivalent dose in 2-Gy fractions (EQD{sub 2}). Using multivariable logistic regression analyses, we examined the associations between cancer treatment and valvular abnormalities. Results: We identified 225 mainly mild echocardiographic valvular abnormalities in 169 of 545 CCS (31%) with a cardiac assessment (median follow-up time, 14.9 years [range, 5.1-36.8 years]; median attained age 22.0 years [range, 7.0-49.7 years]). Twenty-four CCS (4.4%) had 31 moderate or higher-graded abnormalities. Most common abnormalities were tricuspid valve disorders (n=119; 21.8%) and mitral valve disorders (n=73; 13.4%). The risk of valvular abnormalities was associated with increasing radiation dose (using EQD{sub 2}) involving the heart region (odds ratio 1.33 per 10 Gy) and the presence of congenital heart disease (odds ratio 3.43). We found no statistically significant evidence that anthracyclines increase the risk. Conclusions: Almost one-third of CCS treated with potentially cardiotoxic therapy had 1 or more asymptomatic, mostly mild valvular abnormalities after a median follow-up of nearly 15 years. The most important risk factors are higher EQD{sub 2} to the heart region and congenital heart disease. Studies with longer follow-up are necessary to investigate the clinical course of asymptomatic valvular abnormalities in

    AIM: To compare outcomes between single and dual en bloc (EB) kidney transplants (KT) from small pediatric donors. METHODS: Monocentric nonprospective review of KTs from pediatric donors ≤ 5 years of age. Dual EB KT was defined as keeping both donor kidneys attached to the inferior vena cava and aorta, which were then used as venous and arterial conduits for the subsequent transplant into a single recipient. Donor age was less useful than either donor weight or kidney size in decision-making for kidney utilization as kidneys from donors < 8 kg or kidneys < 6 cm in length were not transplanted. Post-transplant management strategies were standardized in all patients. RESULTS: From 2002-2015, 59 KTs were performed including 34 dual EB and 25 single KTs. Mean age of donors (17 mo vs 38 mo, P < 0.001), mean weight (11.0 kg vs 17.4 kg, P = 0.046) and male donors (50% vs 84%, P = 0.01) were lower in the dual EB compared to the single KT group, respectively. Mean cold ischemia time (21 h), kidney donor profile index (KDPI; 73% vs 62%) and levels of serum creatinine (SCr, 0.37 mg/dL vs 0.49 mg/dL, all P = NS) were comparable in the dual EB and single KT groups, respectively. Actuarial graft and patient survival rates at 5-years follow-up were comparable. There was one case of thrombosis resulting in graft loss in each group. Delayed graft function incidence (12% dual EB vs 20% single KT, P = NS) was slightly lower in dual EB KT recipients. Initial duration of hospital stay (mean 5.4 d vs 5.6 d) and the one-year incidences of acute rejection (6% vs 16%), operative complications (3% vs 4%), and major infection were comparable in the dual EB and single KT groups, respectively (all P = NS). Mean 12 mo SCr and abbreviated MDRD levels were 1.17 mg/dL vs 1.35 mg/dL and 72.5 mL/min per 1.73 m2 vs 60.5 mL/min per 1.73 m2 (both P = NS) in the dual EB and single KT groups, respectively.

    This report examines long-term and short-term benefits of achieving abstinence from opioids in a sample of opioid addicts who were reevaluated 2.5 years following seeking treatment. Extensive assessment of drug use history and drug-associated problems had been obtained when the subjects applied for treatment. At follow-up evaluations, detailed information was obtained on intervening course of drug use, treatment, legal problems, psychological problems, social functioning, occupational functioning, and medical status. The results were as follows: (1) Achieving abstinence from illicit opioids was associated with concurrent improvement in other aspects of functioning including reduction of criminal activity, improved medical status, improved social functioning, and reduced abuse of other psychoactive substances. However, many of these improvements were reversed immediately if relapse to opioid use occurred. (2) Achieving abstinence was associated with being in drug treatment, especially treatment in a methadone maintenance program. (3) Achievement of abstinence was not successfully predicted by client characteristics measured at entrance into treatment. (4) Long-range benefits of abstinence were detectable in social functioning even for those who had relapsed at the time of follow-up reevaluation. PMID:3687888

    Grass pollen is an important risk factor for allergic rhinitis and asthma in Australia and is the most prevalent pollen component of the aerospora of Brisbane, accounting for 71.6% of the annual airborne pollen load. A 5-year (June 1994-May 1999) monitoring program shows the grass pollen season to occur during the summer and autumn months (December-April), however the timing of onset and intensity of the season vary from year to year. During the pollen season, Poaceae counts exceeding 30 grains m-3 were recorded on 244 days and coincided with maximum temperatures of 28.1 +/- 2.0 °C. In this study, statistical associations between atmospheric grass pollen loads and several weather parameters, including maximum temperature, minimum temperature and precipitation, were investigated. Spearman's correlation analysis demonstrated that daily grass pollen counts were positively associated (P < 0.0001) with maximum and minimum temperature during each sampling year. Precipitation, although considered a less important daily factor (P < 0.05), was observed to remove pollen grains from the atmosphere during significant periods of rainfall. This study provides the first insight into the influence of meteorological variables, in particular temperature, on atmospheric Poaceae pollen counts in Brisbane. An awareness of these associations is critical for the prevention and management of allergy and asthma for atopic individuals within this region.

    We estimate cosmic microwave background (CMB) polarization and temperature power spectra using Wilkinson Microwave Anisotropy Probe (WMAP) 5 year foreground contaminated maps. The power spectrum is estimated by using a model-independent method, which does not utilize directly the diffuse foreground templates nor the detector noise model. The method essentially consists of two steps: (1) removal of diffuse foregrounds contamination by making linear combination of individual maps in harmonic space and (2) cross-correlation of foreground cleaned maps to minimize detector noise bias. For the temperature power spectrum we also estimate and subtract residual unresolved point source contamination in the cross-power spectrum using the point source model provided by the WMAP science team. Our TT, TE, and EE power spectra are in good agreement with the published results of the WMAP science team. We perform detailed numerical simulations to test for bias in our procedure. We find that the bias is small in almost all cases. A negative bias at low l in TT power spectrum has been pointed out in an earlier publication. We find that the bias-corrected quadrupole power (l(l + 1)C{sub l} /2{pi}) is 532 {mu}K{sup 2}, approximately 2.5 times the estimate (213.4 {mu}K{sup 2}) made by the WMAP team.

    This report is based on twenty-eight (26%) of 107 patients included in a protocol for prospective evaluation of elective peritoneo-venous shunting for intractable ascites in cirrhosis. These patients had no other procedures and survived more than 5 years after the operation. All patients were free of ascites except one in whom it was mild. One patient refused follow-up. Shunt patency was assessed in 23 patients. In 14 patients (60.9%), the shunt was obstructed and the superior vena cava was occluded in 5 of them. In 9 patients (39.1%), the shunt was still functioning. No clinical or biological parameters differentiated these two groups of patients. Of the 24 patients who were alcoholics, 2 abstained completely and 20 significantly reduced their drinking habits. In 25 patients, the Pugh's score improved and was A at the time of the study. Seven patients (25.9%) developed a malignant tumor of the oro-pharynx or digestive tract, all other patients were alive and in good health. This study suggests that patients with intractable ascites treated by a peritoneo-venous shunt may survive for a long period. In patients abstaining from heavy drinking, it may function as a therapeutic bridge permitting spontaneous improvement of liver function. The risk of supervening neoplasms suggests that a continuous follow-up of these patients is warranted. PMID:2487384

  10. Halfway between receiving and giving: a relational analysis of doctorate-prepared nurse-scholars' first 5 years after graduation.

    2005-01-01

    The longitudinal, phenomenological study described in this article is unique in exploring doctorally prepared nurses' lives during their first 5 years after graduation. Despite individual differences, there was a definite pattern in the way the 16 female participants internalized a doctoral identity. During the first year, the women asked themselves, "How big do I want my world to be?" In the second year, they were overwhelmed by trying to prove themselves because they equated doctoral identity with conducting research and scholarship. During the third year, they prioritized gradually focusing and determining the direction of their professional endeavors. In the fourth year, they "spent a lot of time creating my piece of the world." By the fifth year, they valued their accomplishments, "This is my world and I am proud of it." In between receiving and giving, most participants developed a network of colleagues who mentored them as scholars. Given that relationship and scholarly identity are linked in the nursing literature, this relational feminist analysis suggests the need for doctoral nurse educators and students to replace the single mentor-mentee model with a collegial one that allows them to mentor one another as scholars during and after doctoral studies.

    Although trauma-associated mortality has fallen in recent decades, and medical care has continued to improve in many fields, the quality of life after experiencing polytrauma has attracted little attention in the literature. This group of patients suffer from persisting physical disabilities. Moreover, they experience long-term social, emotional, and psychological effects that limit/lower considerably their quality of life.We analyzed retrospective data on 147 polytraumatized patients by administering written questionnaires and conducting face-to-face interviews 6 ± 0.8 years after the trauma in consideration of the following validated scores: Glasgow Outcome Scale, European Quality of Life Score, Short Form-36, Trauma Outcome Profile, and Beck Depressions Inventory II.Our analysis of these results reveals that polytraumatized patients suffer from persistent pain and functional disabilities after >5 years. We also observed changes in their socioeconomic situation, as well as psychological after-effects.The rehabilitation of this particular group of patients should not only address their physical disabilities. The psychological after-effects of trauma must be acknowledged and addressed for an even longer period of time. PMID:27175646

    Purpose: We updated our previous report of a phase 2 trial using proton beam radiation therapy to deliver partial breast irradiation (PBI) in patients with early stage breast cancer. Methods and Materials: Eligible subjects had invasive nonlobular carcinoma with a maximal dimension of 3 cm. Patients underwent partial mastectomy with negative margins; axillary lymph nodes were negative on sampling. Subjects received postoperative proton beam radiation therapy to the surgical bed. The dose delivered was 40 Gy in 10 fractions, once daily over 2 weeks. Multiple fields were treated daily, and skin-sparing techniques were used. Following treatment, patients were evaluated with clinical assessments and annual mammograms to monitor toxicity, tumor recurrence, and cosmesis. Results: One hundred subjects were enrolled and treated. All patients completed the assigned treatment and were available for post-treatment analysis. The median follow-up was 60 months. Patients had a mean age of 63 years; 90% had ductal histology; the average tumor size was 1.3 cm. Actuarial data at 5 years included ipsilateral breast tumor recurrence-free survival of 97% (95% confidence interval: 100%-93%); disease-free survival of 94%; and overall survival of 95%. There were no cases of grade 3 or higher acute skin reactions, and late skin reactions included 7 cases of grade 1 telangiectasia. Patient- and physician-reported cosmesis was good to excellent in 90% of responses, was not changed from baseline measurements, and was well maintained throughout the entire 5-year follow-up period. Conclusions: Proton beam radiation therapy for PBI produced excellent ipsilateral breast recurrence-free survival with minimal toxicity. The treatment proved to be adaptable to all breast sizes and lumpectomy cavity configurations. Cosmetic results appear to be excellent and unchanged from baseline out to 5 years following treatment. Cosmetic results may be improved over those reported with photon

    Objectives Hairdressers are exposed to chemicals at the workplace which are known to cause respiratory symptoms and asthma. This study aimed to examine changes in self-reported respiratory symptoms over 5 years, as well as to examine the lung function decline and determine whether it is within the expected range, to assess the dropout rate and reasons for leaving the profession, and to examine the associations between occupational factors and lung function changes at follow-up. Design Prospective study. Setting Female hairdressing salons in Hebron city, Palestine. Participants 170 female hairdressers who participated in a baseline survey in 2008 were followed up in 2013. A total of 161 participants participated in 2013. Outcome measures Change in reported respiratory symptoms and change in lung function over follow-up. Dropout from the profession and reasons for it. Differences between current and former hairdressers in respiratory symptoms and lung function at follow-up. Ambient air ammonia levels in 13 salons. Results Current hairdressers reported more respiratory symptoms in 2013 compared with baseline. Former hairdressers reported fewer symptoms at follow-up. At follow-up, current hairdressers showed a significant decrease in forced vital capacity of 35 mL/year (95% CI 26 to 44 mL/year) and of 31 mL/year (95% CI 25 to 36 mL/year) for forced expiratory volume in 1 s (FEV1). 28 (16%) of the hairdressers quit the job during the 5-year follow-up, 8 (28%) because of health problems. Hairdressers who had been working for 4 years or more at baseline showed a stronger decline in FEV1 compared with those who worked less than 4 years (difference 13, 95% CI 1 to 25). Conclusions Current hairdressers developed more respiratory symptoms and larger lung function decline than former hairdressers during follow-up. Few hairdressers left their profession because of respiratory health problems. Working for more years is associated with lung function decline among
