    ABSTRACT Background: Mitochondrial liver disease (MLD), and in particular mitochondrial DNA (mtDNA) depletion syndrome (MDS) is an important cause of acute liver failure (ALF) in infancy. Early and accurate diagnosis is important because liver transplantation (LT) is often contraindicated. It is unclear which methods are the best to diagnose MLD in the setting of ALF. Objective: The aim of the study was to determine the incidence of MLD in children younger than 2 years with ALF and the utility of routine investigations to detect MLD. Methods: Thirty-nine consecutive infants with ALF were admitted to a single unit from 2009 to 2011. All were extensively investigated using an established protocol. Genes implicated in mitochondrial DNA depletion syndrome were sequenced in all cases and tissue mtDNA copy number measured where available. Results: Five infants (17%) had genetically proven MLD: DGUOK (n = 2), POLG (n = 2), and MPV17 (1). Four of these died, whereas 1 recovered. Two had normal muscle mtDNA copy number and 3 had normal muscle respiratory chain enzymes. An additional 8 children had low hepatic mtDNA copy number but pathogenic mutations were not detected. One of these developed fatal multisystemic disease after LT, whereas 5 who survived remain well without evidence of multisystemic disease up to 6 years later. Magnetic resonance spectroscopy did not distinguish between those with and without MLD. Conclusions: Low liver mtDNA copy number may be a secondary phenomenon in ALF. Screening for mtDNA maintenance gene mutations may be the most efficient way to confirm MLD in ALF in the first 2 years of life. PMID:27482763

  4. Clinical versus actuarial judgment.

    Professionals are frequently consulted to diagnose and predict human behavior; optimal treatment and planning often hinge on the consultant's judgmental accuracy. The consultant may rely on one of two contrasting approaches to decision-making--the clinical and actuarial methods. Research comparing these two approaches shows the actuarial method to be superior. Factors underlying the greater accuracy of actuarial methods, sources of resistance to the scientific findings, and the benefits of increased reliance on actuarial approaches are discussed.

    The developments in theory governing the calculation of mortality rates for use in survival measurements working through the initial basic concept of exposure to risk to the later introduction of stochastic elements are reviewed. I have indicated the way in which actuaries and statisticians who work closely with those in the fields of medicine and biology have, by the exchange of methodologic ideas, come to an identity of approach. Recent new actuarial work and likely future developments in actuarial interests are reviewed.

    Hospital executives often rely on actuaries (and their "black boxes") to determine self-insurance program liabilities and funding contributions. Typically, the hospital supplies the actuary with a myriad of statistics, and eventually the hospital receives a liability estimate and recommended funding level. The mysterious actuarial calculations that occur in between data reporting and receipt of the actuary's report are akin to a black box--a complicated device whose internal mechanism is hidden from or mysterious to the user.

    2007-05-01

    The probability of a type of failure that is not inevitable, but can be precluded by other events such as death, is given by the cumulative incidence function. In cardiac research articles, it has become known as the actual probability, in contrast to the actuarial methods of estimation, usually implemented by the Kaplan-Meier (KM) estimate. Unlike cumulative incidence, KM attempts to predict what the latent failure probability would be if death were eliminated. To do this, the KM method assumes that the risk of dying and the risk of failure are independent. But this assumption is not true for many cardiac applications in which the risks of failure and death are negatively correlated (ie, patients with a higher risk of dying have a lower risk of failure, and patients with a lower risk of death have a higher risk of failure, which is a condition called informative censoring). Recent editorials in two cardiac journals have promoted the use of the KM method (actuarial estimate) for competing risk events (specifically for heart valve performance) and criticized the use of the cumulative incidence (actual) estimates. This report has two aims: to explain the difference between these two estimates and to show why the KM is generally not appropriate. In the process we will rely on alternative representations of the KM estimator (using redistribution to the right and inverse probability weighting) to explain the difference between the two estimates and to show how it may be possible to adjust KM to overcome the informative censoring.

  20. Actuarial assessment of risk among sex offenders.

    PubMed

    Harris, Grant T; Rice, Marnie E

    2003-06-01

    The appraisal of risk among sex offenders has seen recent advances through the advent of actuarial assessments. Statistics derived from Relative Operating Characteristics (ROCs) permit the comparison of predictive accuracies achieved by different instruments even among samples that exhibit different base rates of recidivism. Such statistics cannot, however, solve problems introduced when items from actuarial tools are omitted, when reliability is low, or when there is high between-subject variability in the duration of the follow-up. We present empirical evidence suggesting that when comprehensive actuarial tools (VRAG and SORAG) are scored with high reliability, without missing items, and when samples of offenders have fixed and equal opportunity for recidivism, predictive accuracies are maximized near ROC areas of 0.90. Although the term "dynamic" has not been consistently defined, such accuracies leave little room for further improvement in long-term prediction by dynamic risk factors. We address the mistaken idea that long-term, static risk levels have little relevance for clinical intervention with sex offenders. We conclude that highly accurate prediction of violent criminal recidivism can be achieved by means of highly reliable and thorough scoring of comprehensive multi-item actuarial tools using historical items (at least until potent therapies are identified). The role of current moods, attitudes, insights, and physiological states in causing contemporaneous behavior notwithstanding, accurate prediction about which sex offenders will commit at least one subsequent violent offense can be accomplished using complete information about past conduct.

  3. Actuarial contributions to life table analysis.

    PubMed

    Lew, E A

    1985-05-01

    The correct principles for the construction of life tables and more particularly select life tables were developed by actuaries in England in the first half of the 19th century. Actuaries explored the phenomenon of selection not only between the insured and annuitants but also in the general population, distinguishing among initial temporary selection, antiselection, and class selection. The conclusion was reached early that no such thing as an unselected population exists. Group life insurance experience among the actively employed has been shown to provide a more appropriate standard of expected mortality than general population death rates in studies of medical impairments and occupational hazards at ages under 65 years. Mortality rates derived from the Cancer Prevention Study can serve as a useful standard of expected mortality when the objective is determination of excess mortality compared with ostensibly healthy persons at ages 65 years and older.

    This paper addresses the issue of the role of theory in the actual application of psychotherapeutic operations. Within the present framework, psychotherapeutic effectiveness is seen as an empirical, actuarial process which occurs in an interpersonal setting separate from theoretical considerations. The role of theory is discussed and a rationale for the coexistence of equally 'effective' contradictory theories is presented. Suggestions for future research in the area of behaviour change are made and an argument for the eventual development of a 'therapeutic cookbook' is presented.

  16. Classification accuracy of actuarial risk assessment instruments.

    PubMed

    Neller, Daniel J; Frederick, Richard I

    2013-01-01

    Users of commonly employed actuarial risk assessment instruments (ARAIs) hope to generate numerical probability statements about risk; however, ARAI manuals often do not explicitly report data that are essential for understanding the classification accuracy of the instruments. In addition, ARAI manuals often contain data that have the potential for misinterpretation. The authors of the present article address the accurate generation of probability statements. First, they illustrate how the reporting of numerical probability statements based on proportions rather than predictive values can mislead users of ARAIs. Next, they report essential test characteristics that, to date, have gone largely unreported in ARAI manuals. Then they discuss a graphing method that can enhance the practice of clinicians who communicate risk via numerical probability statements. After the authors review several strategies for selecting optimal cut-off scores, they show how the graphing method can be used to estimate positive predictive values for each cut-off score of commonly used ARAIs, across all possible base rates. They also show how the graphing method can be used to estimate base rates of violent recidivism in local samples.

  17. Youth Actuarial Risk Assessment Tool (Y-ARAT): The development of an actuarial risk assessment instrument for predicting general offense recidivism on the basis of police records.

    PubMed

    van der Put, Claudia E

    2014-06-01

    Estimating the risk for recidivism is important for many areas of the criminal justice system. In the present study, the Youth Actuarial Risk Assessment Tool (Y-ARAT) was developed for juvenile offenders based solely on police records, with the aim to estimate the risk of general recidivism among large groups of juvenile offenders by police officers without clinical expertise. On the basis of the Y-ARAT, juvenile offenders are classified into five risk groups based on (combinations of) 10 variables including different types of incidents in which the juvenile was a suspect, total number of incidents in which the juvenile was a suspect, total number of other incidents, total number of incidents in which co-occupants at the youth's address were suspects, gender, and age at first incident. The Y-ARAT was developed on a sample of 2,501 juvenile offenders and validated on another sample of 2,499 juvenile offenders, showing moderate predictive accuracy (area under the receiver-operating-characteristic curve = .73), with little variation between the construction and validation sample. The predictive accuracy of the Y-ARAT was considered sufficient to justify its use as a screening instrument for the police.

  18. Impact of actuarial assumptions on pension costs: A simulation analysis

    NASA Astrophysics Data System (ADS)

    Yusof, Shaira; Ibrahim, Rose Irnawaty

    2013-04-01

    This study investigates the sensitivity of pension costs to changes in the underlying assumptions of a hypothetical pension plan in order to gain a perspective on the relative importance of the various actuarial assumptions via a simulation analysis. Simulation analyses are used to examine the impact of actuarial assumptions on pension costs. There are two actuarial assumptions will be considered in this study which are mortality rates and interest rates. To calculate pension costs, Accrued Benefit Cost Method, constant amount (CA) modification, constant percentage of salary (CS) modification are used in the study. The mortality assumptions and the implied mortality experience of the plan can potentially have a significant impact on pension costs. While for interest rate assumptions, it is inversely related to the pension costs. Results of the study have important implications for analyst of pension costs.

  19. Actuarial risk assessment: commentary on Berlin et al.

    PubMed

    Hart, Stephen D

    2003-10-01

    F. S. Berlin, N. W. Galbreath, B. Geary, and G. McGlone (this issue) have raised some important questions regarding the use of acturial risk assessment instruments in sex offender civil commitment proceedings, also known as sexually violent predator or SVP proceedings. Their primary point is that interpreting the findings of existing actuarial risk assessment instruments is a tricky business because it is not certain whether the extent to which probability estimates derived from group data can be applied to individual cases. I agree completely with Berlin et al. on this point, but disagree with them concerning the extent to which probability estimates--and, therefore, actuarial instruments--are legally relevant in SVP proceedings. I outline some potential problems with respect to the legal admissibility of actuarial instruments, including their legal relevance.

  20. Sex offenders and actuarial risk assessments: ethical considerations.

    PubMed

    Campbell, Terence W

    2003-01-01

    When assessing the recidivism risk of previously convicted sex offenders, the relevant ethical standards and practice guidelines obligate psychologists to acknowledge numerous limits related to their data and conclusions. For the actuarial instruments used in these assessments, the highest rates of classification accuracy are associated with greater specificity compared with sensitivity. Selecting cut-off scores to maximize sensitivity results in an inordinate frequency of false positive classifications. Attempts at maximizing specificity create an undesirable frequency of false negative classifications.Unfortunately, adjusted actuarial assessment cannot remedy these problems created by the sensitivity-specificity tradeoff. As an unstandardized procedure, the accuracy of adjusted actuarial assessment is severely limited. Consequently, civil proceedings for previously convicted sexual offenders rely on assessments of very limited accuracy. Undertaking these assessments, therefore, may be inconsistent with relevant ethical standards and practice guidelines.

  18. Connecting clinical and actuarial prediction with rule-based methods.

    PubMed

    Fokkema, Marjolein; Smits, Niels; Kelderman, Henk; Penninx, Brenda W J H

    2015-06-01

    Meta-analyses comparing the accuracy of clinical versus actuarial prediction have shown actuarial methods to outperform clinical methods, on average. However, actuarial methods are still not widely used in clinical practice, and there has been a call for the development of actuarial prediction methods for clinical practice. We argue that rule-based methods may be more useful than the linear main effect models usually employed in prediction studies, from a data and decision analytic as well as a practical perspective. In addition, decision rules derived with rule-based methods can be represented as fast and frugal trees, which, unlike main effects models, can be used in a sequential fashion, reducing the number of cues that have to be evaluated before making a prediction. We illustrate the usability of rule-based methods by applying RuleFit, an algorithm for deriving decision rules for classification and regression problems, to a dataset on prediction of the course of depressive and anxiety disorders from Penninx et al. (2011). The RuleFit algorithm provided a model consisting of 2 simple decision rules, requiring evaluation of only 2 to 4 cues. Predictive accuracy of the 2-rule model was very similar to that of a logistic regression model incorporating 20 predictor variables, originally applied to the dataset. In addition, the 2-rule model required, on average, evaluation of only 3 cues. Therefore, the RuleFit algorithm appears to be a promising method for creating decision tools that are less time consuming and easier to apply in psychological practice, and with accuracy comparable to traditional actuarial methods.

    1989-09-05

    This paper gives details of a model for forecasting AIDS, developed for actuarial purposes, but used also for population projections. The model is only appropriate for homosexual transmission, but it is age-specific, and it allows variation in the transition intensities by age, duration in certain states and calendar year. The differential equations controlling transitions between states are defined, the method of numerical solution is outlined, and the parameters used in five different Bases of projection are given in detail. Numerical results for the population of England and Wales are shown.

    PubMed

    Sreenivasan, S; Kirkish, P; Garrick, T; Weinberger, L E; Phenix, A

    2000-01-01

    Risk assessment in the area of identification of violence has been dichotomized by several prominent researchers as the "clinical approach" versus the "actuarial method". The proponents of the actuarial approach argue for actuarially derived decisions to replace existing clinical practice. The actuarial method requires no clinical input, just a translation of the relevant material from the records to calculate the risk score. A risk appraisal approach based upon a sole actuarial method raises several questions: those of public safety, peer-accepted standards of practice, liability issues, and concordance with evidence-based medicine practice. We conclude that the sole actuarial approach fails to satisfy these critical issues.

  3. An actuarial approach to retrofit savings in buildings

    SciTech Connect

    Subbarao, Krishnappa; Etingov, Pavel V.; Reddy, T. A.

    2014-01-01

    An actuarial method has been developed for determining energy savings from retrofits from energy use data for a number of buildings. This method should be contrasted with the traditional method of using pre- and post-retrofit data on the same building. This method supports the U.S. Department of Energy Building Performance Database of real building performance data and related tools that enable engineering and financial practitioners to evaluate retrofits. The actuarial approach derives, from the database, probability density functions (PDFs) for energy savings from retrofits by creating peer groups for the user’s pre post buildings. From the energy use distribution of the two groups, the savings PDF is derived. This provides the basis for engineering analysis as well as financial risk analysis leading to investment decisions. Several technical issues are addressed: The savings PDF is obtained from the pre- and post-PDF through a convolution. Smoothing using kernel density estimation is applied to make the PDF more realistic. The low data density problem can be mitigated through a neighborhood methodology. Correlations between pre and post buildings are addressed to improve the savings PDF. Sample size effects are addressed through the Kolmogorov--Smirnov tests and quantile-quantile plots.

  11. Different actuarial risk measures produce different risk rankings for sexual offenders.

    PubMed

    Barbaree, Howard E; Langton, Calvin M; Peacock, Edward J

    2006-10-01

    Percentile ranks were computed for N=262 sex offenders using each of 5 actuarial risk instruments commonly used with adult sex offenders (RRASOR, Static-99, VRAG, SORAG, and MnSOST-R). Mean differences between percentile ranks obtained by different actuarial measures were found to vary inversely with the correlation between the actuarial scores. Following studies of factor analyses of actuarial items, we argue that the discrepancies among actuarial instruments can be substantially accounted for by the way in which the factor Antisocial Behavior and various factors reflecting sexual deviance are represented among the items contained in each instrument. In the discussion, we provide guidance to clinicians in resolving discrepancies between instruments and we discuss implications for future developments in sex offender risk assessment.

    2003-09-01

    Four actuarial instruments for the prediction of violent and sexual reoffending (the Violence Risk Appraisal Guide [VRAG], Sex Offender Risk Appraisal Guide [SORAG], Rapid Risk Assessment for Sex Offender Recidivism [RRASOR] and Static-99) were evaluated in 4 samples of sex offenders (N = 396). Although all 4 instruments predicted violent (including sexual) recidivism and recidivism known to be sexually motivated, areas under the receiver operating characteristic (ROC) were consistently higher for the VRAG and the SORAG. The instruments performed better when there were fewer missing items and follow-up time was fixed, with an ROC area up to .84 for the VRAG, for example, under such favorable conditions. Predictive accuracy was higher for child molesters than for rapists, especially for the Static-99 and the RRASOR. Consistent with past research, survival analyses revealed that those offenders high in both psychopathy and sexual deviance were an especially high-risk group.

    PubMed

    Steadman, H J; Silver, E; Monahan, J; Appelbaum, P S; Robbins, P C; Mulvey, E P; Grisso, T; Roth, L H; Banks, S

    2000-02-01

    Since the 1970s, a wide body of research has suggested that the accuracy of clinical risk assessments of violence might be increased if clinicians used actuarial tools. Despite considerable progress in recent years in the development of such tools for violence risk assessment, they remain primarily research instruments, largely ignored in daily clinical practice. We argue that because most existing actuarial tools are based on a main effects regression approach, they do not adequately reflect the contingent nature of the clinical assessment processes. To enhance the use of actuarial violence risk assessment tools, we propose a classification tree rather than a main effects regression approach. In addition, we suggest that by employing two decision thresholds for identifying high- and low-risk cases--instead of the standard single threshold--the use of actuarial tools to make dichotomous risk classification decisions may be further enhanced. These claims are supported with empirical data from the MacArthur Violence Risk Assessment Study.

  19. A Bayesian approach to the group versus individual prediction controversy in actuarial risk assessment.

    PubMed

    Scurich, Nicholas; John, Richard S

    2012-06-01

    Recent attempts to indict the use of actuarial risk assessment instruments have relied on confidence intervals to demonstrate that risk estimates derived at the group level do not necessarily apply to any specific individual within that group. This article contends that frequentist confidence intervals are inapposite to the current debate. Instead, Bayesian credible intervals are necessary-in principle-to accomplish what commentators are concerned about: describing the precision of an actuarial risk estimate. After illustrating both the calculation and interpretation of credible intervals, this article shows how such intervals can be used to characterize the precision of actuarial risk estimates. It then explores the legal implications of wide and overlapping intervals. Contrary to what detractors claim, the fact that risk estimate intervals overlap is not a germane to legal (logical) relevance, and therefore actuarial risk estimates cannot be per se "inadmissible" on this basis.

  1. Applying a forensic actuarial assessment (the Violence Risk Appraisal Guide) to nonforensic patients.

    PubMed

    Harris, Grant T; Rice, Marnie E; Camilleri, Joseph A

    2004-09-01

    The actuarial Violence Risk Appraisal Guide (VRAG) was developed for male offenders where it has shown excellent replicability in many new forensic samples using officially recorded outcomes. Clinicians also make decisions, however, about the risk of interpersonal violence posed by nonforensic psychiatric patients of both sexes. Could an actuarial risk assessment developed for male forensic populations be used for a broader clientele? We modified the VRAG to permit evaluation using data from the MacArthur Violence Risk Assessment Study that included nonforensic male and female patients and primarily self-reported violence. The modified VRAG yielded a large effect size in the prediction of dichotomous postdischarge severe violence over 20 and 50 weeks. Accuracy of VRAG predictions was unrelated to sex. The results provide evidence about the robustness of comprehensive actuarial risk assessments and the generality of the personal factors that underlie violent behavior.

  2. Monitoring Actuarial Present Values of Term Life Insurance By a Statistical Process Control Chart

    Tracking performance of life insurance or similar insurance policy using standard statistical process control chart is complex because of many factors. In this work, we present the difficulty in doing so. However, with some modifications of the SPC charting framework, the difficulty can be manageable to the actuaries. So, we propose monitoring a simpler but natural actuarial quantity that is typically found in recursion formulas of reserves, profit testing, as well as present values. We shared some simulation results for the monitoring process. Additionally, some advantages of doing so is discussed.

  5. Choosing the 'best' plan in a health insurance exchange: actuarial value tells only part of the story.

    PubMed

    2012-08-01

    In the health insurance exchanges that will come online in 2014, consumers will be able to compare health plans with respect to actuarial value, or the percentage of health care costs that a plan would pay for a standard population. This analysis illustrates the out-of-pocket costs that might result from plans with various plan designs and actuarial values. We find that average out-of-pocket expense declines as actuarial values rise, but two plans with similar actuarial values can produce very different outcomes for a given person. The overall affordability of a plan also will be influenced by age rating, income-related premium subsidies, and out-of-pocket subsidies. Actuarial value is a useful starting point for selecting a plan, but it does not pinpoint which plan will produce the best overall value for a particular person.

  9. The effect of framing actuarial risk probabilities on involuntary civil commitment decisions.

    PubMed

    Scurich, Nicholas; John, Richard S

    2011-04-01

    Despite a proliferation of actuarial risk assessment instruments, empirical research on the communication of violence risk is scant and there is virtually no research on the consumption of actuarial risk assessment. Using a 2 × 3 Latin Square factorial design, this experiment tested whether decision-makers are sensitive to varying levels of risk expressed probabilistically and whether the framing of actuarial risk probabilities is consequential for commitment decisions. Consistent with research on attribute framing, in which describing an attribute in terms of its complement leads to different conclusions, this experiment found that the way actuarial risk estimates are framed leads to disparate commitment decisions. For example, risk framed as 26% probability of violence generally led decision-makers to authorize commitment, whereas the same risk framed in the complement, a 74% probability of no violence, generally led decision-makers to release. This result was most pronounced for moderate risk levels. Implications for the risk communication format debate, forensic practice and research are discussed.

  10. From group data to useful probabilities: the relevance of actuarial risk assessment in individual instances.

    PubMed

    Mossman, Douglas

    2015-03-01

    Probability plays a ubiquitous role in decision-making through a process in which we use data from groups of past outcomes to make inferences about new situations. Yet in recent years, many forensic mental health professionals have become persuaded that overly wide confidence intervals render actuarial risk assessment instruments virtually useless in individual assessments. If this were true, the mathematical properties of probabilistic judgments would preclude forensic clinicians from applying group-based findings about risk to individuals. As a consequence, actuarially based risk estimates might be barred from use in legal proceedings. Using a fictional scenario, I seek to show how group data have an obvious application to individual decisions. I also explain how misunderstanding the aims of risk assessment has led to mistakes about how, when, and why group data apply to individual instances. Although actuarially based statements about individuals' risk have many pitfalls, confidence intervals pose no barrier to using actuarial tools derived from group data to improve decision-making about individual instances.

  11. Actuarial senescence in a long-lived orchid challenges our current understanding of ageing.

    2016-11-16

    The dominant evolutionary theory of actuarial senescence-an increase in death rate with advancing age-is based on the concept of a germ cell line that is separated from the somatic cells early in life. However, such a separation is not clear in all organisms. This has been suggested to explain the paucity of evidence for actuarial senescence in plants. We used a 32 year study of Dactylorhiza lapponica that replaces its organs each growing season, to test whether individuals of this tuberous orchid senesce. We performed a Bayesian survival trajectory analysis accounting for reproductive investment, for individuals under two types of land use, in two climatic regions. The mortality trajectory was best approximated by a Weibull model, showing clear actuarial senescence. Rates of senescence in this model declined with advancing age, but were slightly higher in mown plots and in the more benign climatic region. At older ages, senescence was evident only when accounting for a positive effect of reproductive investment on mortality. Our results demonstrate actuarial senescence as well as a survival-reproduction trade-off in plants, and indicate that environmental context may influence senescence rates. This knowledge is crucial for understanding the evolution of demographic senescence and for models of plant population dynamics.

However, there is a lack of direct comparisons of the predictive accuracy of clinical judgment and actuarial risk scales for sexual offenders. We followed up 121 male sex offenders (> or =18 years) subjected to pre-trial forensic psychiatric assessment in Denmark in 1978-1992 (mean post-detainment time = 16.4 years) to compare the predictive validity of unstructured clinical judgment of recidivism risk with that of the well-established Static-99 (Hanson and Thornton, Law and Human Behavior 24:119-136, 2000) and an extension of the Static-99, the Static-2002 (Hanson and Thornton, Notes on the development of Static-2002 (Rep. No. 2003-01), Public Safety and Emergency Preparedness Canada, Ottawa, Canada, 2003). The predictive accuracy of unguided judgment did not exceed chance for any sexual, severe sexual or any violent (sexual or non-sexual) reconviction (AUCs of the ROC curve = 0.52, 95%CI = 0.41-0.63; 0.50, 95%CI = 0.34-0.67; and 0.57, 95%CI = 0.40-0.73, respectively). In contrast, all three outcomes were predicted significantly better than chance by the Static-99 (AUC = 0.62, 95%CI = 0.52-0.72; 0.72, 95%CI = 0.59-0.84; and 0.71, 95%CI = 0.56-0.86) and the Static-2002 (AUC = 0.67, 95%CI = 0.57-0.77; 0.69, 95%CI = 0.56-0.83; and 0.70, 95%CI = 0.55-0.86). Static-99 outperformed clinical judgment for sexual recidivision (chi(2) = 5.11, df = 1, p < .05). The Static-2002 was significantly more accurate for the prediction of any sexual recidivism as compared to unguided clinical judgment but its advantage fell just short of statistical significance for severe sexual recidivism (chi(2) = 3.56, df = 1, p = 0.06). When tested for recidivism within 2 years, none of the three prediction methods yielded results significantly better than chance for any outcome. This direct trial of the unguided clinical method argues against its

    The Static-99, an actuarial rating method, is employed to conduct sexual violence risk assessment in legal contexts. The proponents of the Static-99 dismiss clinical judgment as not empirical. Two elements must be present to apply an actuarial risk model to a specific individual: sample representativeness and uniform measurement of outcome. This review demonstrates that both of these elements are lacking in the normative studies of the Static-99 and its revised version, the Static-99R. Studies conducted since the publication of the Static-99 have not replicated the original norms. Sexual recidivism rates for the same Static-99 score vary widely, from low to high, depending on the sample used. A hypothetical case example is presented to illustrate how the solitary application of the Static-99 or Static-99R recidivism rates to the exclusion of salient clinical factors for identifying sexual dangerousness can have serious consequences for public safety.

    In this paper we use a market-consistent approach to calculate present value of obligation of a companies' post-employment benefit in accordance with PSAK-24 (the Indonesian accounting standard). We set some actuarial assumption such as Indonesian TMI 2011 mortality tables for mortality assumptions, accumulated salary function for wages assumption, a scaled (to mortality) disability assumption and a pre-defined turnover rate for termination assumption. For economic assumption, we use binomial tree method with estimated discount rate as its average movement. In accordance with PSAK-24, the Projected Unit Credit method has been adapted to determine the present value of obligation (actuarial liability), so we use this method with a modification in its discount function.

    This study examines the predictive validity of the most commonly used risk assessment instruments for sexual offenders: Static-99, Rapid Risk Assessment for Sexual Offense Recidivism, Sex Offender Risk Appraisal Guide, Sexual Violence Risk-20, and Psychopathy Checklist-Revised in a prospective research design. Although risk assessment is part of a regime leading to various efforts to reduce risk by treatment and aftercare, all instruments show good predictive validity. However, depending on the instrument, recidivism category, and subgroup, the predictive accuracy varies markedly. Furthermore, the authors fail to demonstrate predictive validity for sexual violent reoffences-for the whole sample and for all subgroups. The results, nevertheless, support the utility and predictive validity of actuarial risk assessment complementary to treatment efforts to reduce risk. On the other hand, forensic practitioners have to be aware of the limitations of actuarial risk assessment methods, in particular as regards to variable predictive accuracy for different sexual offender subgroups and reoffence categories.

    Hospital-based partner assault clinics are a relatively recent addition to the community response to partner violence. In this study, 66% of 111 women attending hospital clinics for partner assault were physically injured and 43% reported death threats. Few concurrently used other services (shelters or police) and most relied on female friends and relatives for help. Many participants who currently lived with the perpetrator were contemplating leaving but only a third had made plans to do so. Participants faced an unusually high risk of future assault, according to both victim interview using the ODARA actuarial risk assessment and their own perceptions. Findings imply an important role for partner assault clinics and the feasibility of the victim service sector's using the same actuarial risk assessments as the criminal justice system.

    Extra-renal pelvis (ERpel) is a common ultrasonographic finding among neonates who have undergone recurrent ultrasound examinations for a better definition of prenatal renal pelvic dilatation. This study tries to determine whether or not ERpel has important prognostic implications. Seventy-nine neonates (17 female) were examined. All had a diagnosis of prenatal renal pelvis dilatation, which was shown by postnatal ultrasound to be ERpel. Sixty ERpel neonates were examined 1.5 months to 2.5 months after the ultrasound (US) diagnosis by both Tc-99m diethylene triamine penta-acetic acid (DPTA) dynamic renal scanning and (99m)Tc-pertechnetate direct cystography. Clinical assessment, urine cultures and renal ultrasound follow-up were maintained for 2 years. The proportion of urinary tract infections (UTIs) in patients with ERpel was compared with that of the total neonatal and infantile population with normal US scans in the region of our hospital. Associated minor congenital malformations were found in 12 of 79 neonates (15.2%). Four had a family history of ERpel. Among 60 neonates who underwent renal scanning, 36 (60%) were found to have urinary retention in the collecting system. Another nine (15%) had vesico-ureteral (VU) reflux, of which seven had urinary retention. Fifteen (25%) showed normal isotope imaging. Urinary tract infection was diagnosed in 16 ERpel neonates in whom only one exhibited VU reflux (grade 2). The incidence of neonatal UTI in the ERpel group was more than that of either neonatal or infantile UTI in those with normal US scans in the local population (20.2% vs 1.2% and 4.3%, respectively). Fifty-three infants completed a 2-year follow-up. Repeat renal ultrasonography indicated that one infant (1.8%) had developed bilateral hydronephrosis, 12 (22.6%) had unchanged findings, 18 (40%) showed an improvement (decrease of ERpel width or resolution in one side) and, in 22 (41.5%) infants, the condition had resolved.

    While CMS actuaries say the 2010 reform law will not slow the nation's healthcare spending in the coming decade, Mary Grealy, of the Healthcare Leadership Council, says the law "was basically a coverage bill. We just didn't get to the other half, which would be aimed at the cost-drivers in the system." She adds that the healthcare system will not control ongoing steep increases in spending until additional legislation reshapes the dominant public insurance plans.

    Abstract Background/aim Clinical risk models are commonly used to predict short‐term coronary artery bypass grafting (CABG) mortality but are less commonly used to predict long‐term mortality. The added value of long‐term mortality clinical risk models over traditional actuarial models has not been evaluated. To address this, the predictive performance of a long‐term clinical risk model was compared with that of an actuarial model to identify the clinical variable(s) most responsible for any differences observed. Methods Long‐term mortality for 1028 CABG patients was estimated using the Hannan New York State clinical risk model and an actuarial model (based on age, gender, and race/ethnicity). Vital status was assessed using the Social Security Death Index. Observed/expected (O/E) ratios were calculated, and the models' predictive performances were compared using a nested c‐index approach. Linear regression analyses identified the subgroup of risk factors driving the differences observed. Results Mortality rates were 3%, 9%, and 17% at one‐, three‐, and five years, respectively (median follow‐up: five years). The clinical risk model provided more accurate predictions. Greater divergence between model estimates occurred with increasing long‐term mortality risk, with baseline renal dysfunction identified as a particularly important driver of these differences. Conclusions Long‐term mortality clinical risk models provide enhanced predictive power compared to actuarial models. Using the Hannan risk model, a patient's long‐term mortality risk can be accurately assessed and subgroups of higher‐risk patients can be identified for enhanced follow‐up care. More research appears warranted to refine long‐term CABG clinical risk models. doi: 10.1111/jocs.12665 (J Card Surg 2016;31:23–30) PMID:26543019

    Many analyses of human populations have found that age-specific mortality rates increase faster across most of adulthood when overall mortality levels decline. This contradicts the relationship often expected from Williams' classic hypothesis about the effects of natural selection on the evolution of senescence. More likely, much of the within-species difference in actuarial aging is not due to variation in senescence, but to the strength of filters on the heterogeneity of frailty in older survivors. A challenge to this differential frailty hypothesis was recently posed by an analysis of life tables from historical European populations and traditional societies that reported variation in actuarial aging consistent with Williams' hypothesis after all. To investigate the challenge, we reconsidered those cases and aging measures. Here we show that the discrepancy depends on Ricklefs' aging rate measure, ω, which decreases as mortality levels drop because it is an index of mortality level itself, not the rate of increase in mortality with age. We also show unappreciated correspondence among the parameters of Gompertz-Makeham and Weibull survival models. Finally, we compare the relationships among mortality parameters of the traditional societies and the historical series, providing further suggestive evidence that differential heterogeneity has strong effects on actuarial aging.

  4. Valuing structured professional judgment: predictive validity, decision-making, and the clinical-actuarial conflict.

    PubMed

    2013-01-01

    Structured professional judgment (SPJ) has received considerable attention as an alternative to unstructured clinical judgment and actuarial assessment, and as a means of resolving their ongoing conflict. However, predictive validity studies have typically relied on receiver operating characteristic (ROC) analysis, the same technique commonly used to validate actuarial assessment tools. This paper presents SPJ as distinct from both unstructured clinical judgment and actuarial assessment. A key distinguishing feature of SPJ is the contribution of modifiable factors, either dynamic or protective, to summary risk ratings. With modifiable factors, the summary rating scheme serves as a prognostic model rather than a classification procedure. However, prognostic models require more extensive and thorough predictive validity testing than can be provided by ROC analysis. It is proposed that validation should include calibration and reclassification techniques, as well as additional measures of discrimination. Several techniques and measures are described and illustrated. The paper concludes by tracing the limitations of ROC analysis to its philosophical foundation and its origin as a statistical theory of decision-making. This foundation inhibits the performance of crucial tasks, such as determining the sufficiency of a risk assessment and examining the evidentiary value of statistical findings. The paper closes by noting a current effort to establish a viable and complementary relationship between SPJ and decision-making theory.

    An actuarial risk assessment instrument can be considered valid if independent investigations using novel samples can replicate the findings of the instrument's development study. In order for a study to qualify as a replication, it has to adhere to the methodological protocol of the development study with respect to key design characteristics, as well as ensuring that manual-recommended guidelines of test administration have been followed. A systematic search was conducted to identify predictive validity studies (N = 84) on three commonly used actuarial instruments: the Violence Risk Appraisal Guide (VRAG), the Sex Offender Risk Appraisal Guide (SORAG), and the Static-99. Sample (sex, age, criminal history) and design (follow-up, attrition, recidivism) characteristics, as well as markers of assessment integrity (scoring reliability, item omissions, prorating procedure), were extracted from 84 studies comprising 108 samples. None of the replications matched the development study of the instrument they were attempting to cross-validate with respect to key sample and design characteristics. Furthermore none of the replications strictly followed the manual-recommended guidelines for the instruments' administration. Additional replication studies that follow the methodological protocols outlined in actuarial instruments' development studies are needed before claims of generalizability can be made.

    Background By a wide margin, lung cancer is the most significant cause of cancer death in the United States and worldwide. The incidence of lung cancer increases with age, and Medicare beneficiaries are often at increased risk. Because of its demonstrated effectiveness in reducing mortality, lung cancer screening with low-dose computed tomography (LDCT) imaging will be covered without cost-sharing starting January 1, 2015, by nongrandfathered commercial plans. Medicare is considering coverage for lung cancer screening. Objective To estimate the cost and cost-effectiveness (ie, cost per life-year saved) of LDCT lung cancer screening of the Medicare population at high risk for lung cancer. Methods Medicare costs, enrollment, and demographics were used for this study; they were derived from the 2012 Centers for Medicare & Medicaid Services (CMS) beneficiary files and were forecast to 2014 based on CMS and US Census Bureau projections. Standard life and health actuarial techniques were used to calculate the cost and cost-effectiveness of lung cancer screening. The cost, incidence rates, mortality rates, and other parameters chosen by the authors were taken from actual Medicare data, and the modeled screenings are consistent with Medicare processes and procedures. Results Approximately 4.9 million high-risk Medicare beneficiaries would meet criteria for lung cancer screening in 2014. Without screening, Medicare patients newly diagnosed with lung cancer have an average life expectancy of approximately 3 years. Based on our analysis, the average annual cost of LDCT lung cancer screening in Medicare is estimated to be $241 per person screened. LDCT screening for lung cancer in Medicare beneficiaries aged 55 to 80 years with a history of ≥30 pack-years of smoking and who had smoked within 15 years is low cost, at approximately $1 per member per month. This assumes that 50% of these patients were screened. Such screening is also highly cost-effective, at <$19,000 per life

    Respiratory syncytial virus (RSV) is the most frequent agent of acute lower respiratory diseases and creates a significant burden of disease in children under 5 years all over the world. RSV causes severe lower respiratory tract infections (LRTI) that require hospitalization, especially in children ≤2 years. The aim of this study was to determine the incidence of RSV in children ≤2 years of age hospitalized for LRTI. Children ≤2 years of age hospitalized for one year for LRTI in the three largest hospitals of Bursa City Center, Turkey were evaluated. These three hospitals comprise 67.5% of all child beds in central Bursa, so this study allows us to evaluate the total disease burden and hospitalization incidence in central Bursa. Nasal swabs of the children were evaluated with RSV Respi- Strip (Coris Bioconcept Organization). A total of 671 children were hospitalized for LRTI, and 254 (37.9%) had at least one hospitalization that was positive for RSV. Of all patients with LRTI, 54.8% (368/671) were hospitalized for acute bronchiolitis, while 45.2% (303/671) were hospitalized for pneumonia. Of patients with acute bronchiolitis or pneumonia, 41% (151/368) and 34% (103/303) were RSV+, respectively. Of RSV+ hospitalized children, 59.5% (151/254) were diagnosed as acute bronchiolitis and 40.5% (103/254) as pneumonia. The annual incidences of hospitalization due to LRTI, acute bronchiolitis and pneumonia were 20.5/1000, 11.2/1000 and 9.3/1000, respectively, in children ≤2 years of age. The annual incidences of hospitalization due to RSV+ LRTI, acute bronchiolitis and pneumonia were found as 7.8/1000, 4.6/1000 and 3.2/1000, respectively, in children ≤2 years of age. More than one-third of all children hospitalized with LRTI (38.3%, n=257) were in the 0-3 months age group. Compared to other age groups, RSV positivity was highest in that age group for acute bronchiolitis (57%), pneumonia (39.5%) and also total children with LRTI (47.9%). RSV is a very important

    G.C. Williams's 1957 hypothesis famously argues that higher age-independent, or "extrinsic," mortality should select for faster rates of senescence. Long-lived species should therefore show relatively few deaths from extrinsic causes such as predation and starvation. Theoretical explorations and empirical tests of Williams's hypothesis have flourished in the past decade but it has not yet been tested empirically among humans. We test Williams's hypothesis using mortality data from subsistence populations and from historical cohorts from Sweden and England/Wales, and examine whether rates of actuarial aging declined over the past two centuries. We employ three aging measures: mortality rate doubling time (MRDT), Ricklefs's omega, and the slope of mortality hazard from ages 60-70, m'(60-70), and model mortality using both Weibull and Gompertz-Makeham hazard models. We find that (1) actuarial aging in subsistence societies is similar to that of early Europe, (2) actuarial senescence has slowed in later European cohorts, (3) reductions in extrinsic mortality associate with slower actuarial aging in longitudinal samples, and (4) men senesce more rapidly than women, especially in later cohorts. To interpret these results, we attempt to bridge population-based evolutionary analysis with individual-level proximate mechanisms.

    The assessment of the potential for sexual violence is one of three prongs that must be met to satisfy the requirements for civil confinement of dangerous sex offenders in the 21 U.S. jurisdictions that have these laws. In a recent issue of The Journal, Sreenivasan et al. argued that, because of a host of methodological problems, actuarial risk assessment methods in general and the Static-99 and its progeny in particular are insufficient for accurate assessment of risk for dangerous sex offenders. They propose using a combination of clinical judgment with actuarial science as a solution. This analysis and review of Sreenivasan et al. reveals and corrects flaws in the arguments they employed to support their position and shows how the combination of actuarial science with clinical judgment is more error prone than the actuarial approach only, and cannot be forensically defended in court. Recommendations on reporting Static-99R data in expert testimony are provided, taking into account the limitations of the instrument.

    Optimality theories of ageing predict that the balance between reproductive effort and somatic maintenance determines the rate of ageing. Laboratory studies find that increased reproductive effort shortens lifespan, but through increased short-term mortality rather than ageing. In contrast, high fecundity in early life is associated with accelerated senescence in free-living vertebrates, but these studies are non-experimental. We performed lifelong brood size manipulation in free-living jackdaws. Actuarial senescence--the increase in mortality rate with age--was threefold higher in birds rearing enlarged- compared to reduced broods, confirming a key prediction of the optimality theory of ageing. Our findings contrast with the results of single-year brood size manipulation studies carried out in many species, in which there was no overall discernible manipulation effect on mortality. We suggest that our and previous findings are in agreement with predictions based on the reliability theory of ageing and propose further tests of this proposition.

    Comparing the mortality characteristics of different cohorts is an essential process in the life insurance industry. Pseudodisease, lead-time bias, and length bias, which are critical to determining the value of cancer screening, have close analogues in life insurance company management, including the temporal impact of underwriting. Ratios of all-cause mortality rates for cancer cohorts relative to standard population mortality rates can provide insights into early stage and late stage mortality differences, differences by age, sex, race, and histology, and allow modeling of biases associated with early stage detection or screening protocols. The Surveillance, Epidemiology and End Results (SEER) data set has characteristics that allow efficient application of actuarial techniques. We show the mortality burden associated with treated early stage lung cancer and that identifying all lung cancers at early stage could reduce US lung cancer deaths by over 70,000 per year.

  19. Risk of violence by psychiatric patients: beyond the "actuarial versus clinical" assessment debate.

    PubMed

    Buchanan, Alec

    2008-02-01

    Recently adopted statistical approaches improve researchers' ability to describe what is, and what is not, possible in the prediction of violence by psychiatric patients. At the base rates of violence routinely encountered in outpatient settings, current assessment methods would require hospital admission of large numbers of patients who are potential offenders in order to prevent the actual offending of a few. Suggestions that substantially greater accuracy is possible for short-term predictions, for particular symptom clusters, and for particular offenses have yet to be tested and confirmed. Further research may improve this state of affairs, for instance, by concentrating on particular patient groups. There are reasons to suspect that any improvement will be limited. Clinical practice, however, is likely to continue to require the assessment of a patient's potential for acting violently. Future research should aid such assessments by clarifying the mechanisms by which risk factors correlate with violence and by establishing the clinical usefulness of actuarial scales.

    Principal components analysis was conducted on items contained in actuarial instruments used with adult sex offenders, including: the Rapid Assessment of Sex Offender Risk for Recidivism (RASORR), the Static-99, the Violence Risk Appraisal Guide (VRAG), the Sex Offender Risk Appraisal Guide (SORAG), and the Minnesota Sex Offender Screening Tool-Revised (MnSOST-R). In a data set that included child molesters and rapists (N = 311), six interpretable components were identified: Antisocial Behavior, Child Sexual Abuse, Persistence, Detached Predatory Behavior, Young and Single, and Male Victim(s). The RRASOR was highly correlated with Persistence, and the VRAG and SORAG were highly correlated with Antisocial Behavior. Antisocial Behavior was a significant predictor of violent recidivism, while Persistence and Child Sexual Abuse were significant predictors of sexual recidivism.

    For the practitioner, choosing diagnosis codes is a non-intuitive operation. Mistakes are frequent, causing severe consequences on healthcare performance evaluation and funding. French physicians have to assign a code to all their activities and are frequently prone to these errors. Given that most of the time and particularly for chronic diseases indexed information is already available, we propose a tool named AnterOcod, in order to support the medical coding task. It suggests the list of most relevant plausible codes, predicted from the patient's earlier hospital stays, according to a set of previously utilized diagnosis codes. Our method applies the estimation of code reappearance rates, based on an equivalent approach to actuarial survival curves. Around 33% of the expected correct diagnosis codes were retrieved in this manner, after evaluating 998 discharge abstracts, significantly improving the coding task.

    An actuarial tool, the Ontario Domestic Assault Risk Assessment (ODARA), predicts recidivism using only variables readily obtained by frontline police officers. Correctional settings permit more comprehensive assessments. In a subset of ODARA construction and cross-validation cases, 303 men with a police record for wife assault and a correctional system file, the VRAG, SARA, Danger Assessment, and DVSI also predicted recidivism, but the Hare Psychopathy Checklist (PCL-R) best improved prediction of recidivism, occurrence, frequency, severity, injury, and charges. In 346 new cases, ODARA and PCL-R independently predicted recidivism. An algorithm was derived for a combined instrument, the Domestic Violence Risk Appraisal Guide (DVRAG), and an experience table is presented (N=649). Results indicated the importance of antisociality in wife assault.

    One thousand five hundred ninety-eight patients who underwent cardiac valve replacement were reviewed. One hundred fifty-two patients (10 percent) required a second valve replacement. The indications for repeat valve replacement were prosthetic valve dysfunction in 53 patients (35 percent), development of a new valvular lesion in 46 patients (30 percent), simple closure of a perivalvular leak in 14 patients (9 percent), change of the valve poppet in 13 patients (8 percent), severe hemolysis or emboli in 21 patients (14 percent), and prosthetic valve endocarditis in 5 patients (3 percent). The mean preoperative New York Health Association functional class improved from 3 to 1.5 in the nonreoperated patients and from 2.9 to 1.8 in patients who underwent a second valve replacement. Similarly, the mean cardiac index improved from 2.5 to 2.9 and from 2.5 to 2.8 in nonreoperated and reoperated patients, respectively. The operative mortality rate was 14 percent in the nonreoperated patients and 16 percent at second operation in the reoperated patients. Using actuarial techniques, the risk of repeat valve replacement was 1 to 4 percent per year. Long-term survival was compared between groups. Using actuarial techniques, the estimated survival rates at 1, 5, and 10 years were 89 percent, 69 percent, and 52 percent, respectively in nonreoperated patients and 87 percent, 60 percent, and 37 percent in reoperated patients. This study has documented the excellent improvement in functional and hemodynamic state after second cardiac valve replacement. The operative mortality and long-term survival rates were similar to those of the nonreoperated patients. Patients having repeat cardiac valve replacement can expect good improvement in length and quality of life.

  4. Long-term actuarial survivorship analysis of an interspinous stabilization system.

    In 1986, an interspinous dynamic stabilization system (the prototype of the current Wallis implant) was designed to stiffen unstable operated degenerate lumbar segments with a hard interspinous blocker to limit extension and a tension band around the spinous processes to secure the implant and limit flexion. Restoring physiological mechanical conditions to the treated level(s) while preserving some intervertebral mobility was intended to treat low-back pain related to degenerative instability without increasing stress forces in the adjacent segments. The procedure was easily reversible. If low back pain persisted or recurred, the device was removed and stability was achieved using fusion. The intermediate-term results were promising, but the long-term safety and efficacy of this dynamic interspinous stabilization device has not been previously documented. We retrospectively reviewed the hospital files of all the patients (n = 241) who had this dynamic stabilization system implanted between 1987 and 1995, contacting as many as possible to determine the actuarial survivorship of the system. In this manner, 142 of the 241 patients (58.9%) were contacted by telephone. The endpoints used for the survivorship analysis were 'any subsequent lumbar operation' and 'implant removal'. At 14 years follow-up, values of actuarial survivorship with 95% confidence interval were 75.9 +/- 8.3 and 81.3 +/- 6.8% for the endpoints 'any subsequent lumbar operation' and 'implant removal', respectively. There was no difference in survivorship of multiple-level implants with respect to single-level devices. Although the conclusions of the present study must be tempered by the 41% attrition rate, these findings support the long-term safety of this system, and possibly long-term protective action against adjacent-level degeneration by motion preservation. Outcomes at least equivalent to those of fusion were observed without the primary drawbacks of fusion.

  5. Projections of health care expenditures as a share of the GDP: actuarial and macroeconomic approaches.

    STUDY QUESTION. Can the steady increases in health care expenditures as a share of GDP projected by widely cited actuarial models be rationalized by a macroeconomic model with sensible parameters and specification? DATA SOURCES. National Income and Product Accounts, and Social Security and Health Care Financing Administration are the data sources used in parameters estimates. STUDY DESIGN. Health care expenditures as a share of gross domestic product (GDP) are projected using two methodological approaches--actuarial and macroeconomic--and under various assumptions. The general equilibrium macroeconomic approach has the advantage of allowing an investigation of the causes of growth in the health care sector and its consequences for the overall economy. DATA COLLECTION METHODS. Simulations are used. PRINCIPAL FINDINGS. Both models unanimously project a continued increase in the ratio of health care expenditures to GDP. Under the most conservative assumptions, that is, robust economic growth, improved demographic trends, or a significant moderation in the rate of health care price inflation, the health care sector will consume more than a quarter of national output by 2065. Under other (perhaps more realistic) assumptions, including a continuation of current trends, both approaches predict that health care expenditures will comprise between a third and a half of national output. In the macroeconomic model, the increasing use of capital goods in the health care sector explains the observed rise in relative prices. Moreover, this "capital deepening" implies that a relatively modest fraction of the labor force is employed in health care and that the rest of the economy is increasingly starved for capital, resulting in a declining standard of living.

    In medicine real severe mishaps are rare. On the other hand critical incidents are frequent. Anonymous critical incident reporting systems allow us to learn from these mishaps. This learning process will make our daily clinical work safer Unfortunately, before these systems can be used efficiently our professional culture has to be changed. Everyone in medicine has to admit that errors do occur to see the need for an open discussion. If we really want to learn from errors, we cannot punish the individual, who reported his or her mistake. The interest is primarily in what has happened and why it has happened and not who has committed this mistake. The cause for critical incidents in medicine is in over 80% the human factor Poor communication, work under enormous stress, conflicts and hierarchies are the main cause. This has been known for many years, therefore have already 15 years ago high-tech industries, like e.g. aviation, started to invest in special courses on team training. Medicine is a typical profession were until now only the individual performance decided about the professional career Communication, conflict management, stress management, decision making, risk management, team and team resource management were subjects that have never been taught during our preor postgraduate education. These points are the most important ones for an optimal teamwork. A multimodular course designed together with Swissair (Human Aspect Development medical, HADmedical) helps to cover, as in aviation, the soft factor and behavioural education in medicine and to prepare professionals in health care to work as a real team.

    The incidence of native portal vein thrombosis (PVT) in liver transplant recipients has been reported to range from 2.1 to 13.8%. We have identified an inordinately high incidence of PVT in a consecutive series of U.S. veterans receiving liver transplants. Between October 1989 and February 1994, 88 consecutive U.S. veterans received 99 orthotopic liver transplants under primary Tacrolimus (Prograf, formerly FK506) based immunosuppression. A number of clinical features were examined in an effort to identify risk factors for PVT and outcome was compared to patients without PVT. Native PVT was present in 23/88 (26%) patients. All of these patients were male U.S. veterans with a mean age of 47 years. When compared to the 65 patients without PVT, we found no significant difference with respect to underlying liver disease, age, Childs-Pugh score (mean = 12), UNOS status as defined prior to April 1995 (95% UNOS 3 or 4), previous abdominal surgery, or liver volume. Median blood loss for patients with PVT (21 units of packed red blood cells) was greater than for those without PVT (14 units, P = 0.04). Portal thrombectomy was performed in 11 patients, 11 patients required mesoportal jump grafts, and 1 patient had an interposition graft. Standard veno-venous bypass was used in 10 patients with single bypass utilized for the remainder. Actuarial patient survival for all patients at 1, 2, and 4 years was 88, 85, and 79%, respectively. There was no significant difference in patients with or without PVT. Patients with PVT had poorer graft survival than patients without PVT (86% vs 65%, 1 year; 81% vs 65%, 2 years; 81% vs 61%, 4 years; P = 0.03); however, this was not related to technical problems with the portal venous inflow. PVT occurred in 26% of U.S. veterans undergoing liver transplantation. These patients had significantly higher operative blood loss and poorer graft survival.

  10. A mathematical proof and example that Bayes's Theorem is fundamental to actuarial estimates of sexual recidivism risk.

    PubMed

    Donaldson, Theodore; Wollert, Richard

    2008-06-01

    Expert witnesses in sexually violent predator (SVP) cases often rely on actuarial instruments to make risk determinations. Many questions surround their use, however. Bayes's Theorem holds much promise for addressing these questions. Some experts nonetheless claim that Bayesian analyses are inadmissible in SVP cases because they are not accepted by the relevant scientific community. This position is illogical because Bayes's Theorem is simply a probabilistic restatement of the way that frequency data are combined to arrive at whatever recidivism rates are paired with each test score in an actuarial table. This article presents a mathematical proof and example validating this assertion. The advantages and implications of a logic model that combines Bayes's Theorem and the null hypothesis are also discussed.

  11. Actuarial assessment of sex offender recidivism risk: a cross-validation of the RRASOR and the Static-99 in Sweden.

    2001-12-01

    We cross-validated two actuarial risk assessment tools, the RRASOR (R. K. Hanson, 1997) and the Static-99 (R. K. Hanson & D. Thornton, 1999), in a retrospective follow-up (mean follow-up time = 3.69 years) of all sex offenders released from Swedish prisons during 1993-1997 (N = 1,400, all men, age > or =18 years). File-based data were collected by a researcher blind to the outcome (registered criminal recidivism), and individual risk factors as well as complete instrument characteristics were explored. Both the RRASOR and the Static-99 showed similar and moderate predictive accuracy for sexual reconvictions whereas the Static-99 exhibited a significantly higher accuracy for the prediction of any violent recidivism as compared to the RRASOR. Although particularly the Static-99 proved moderately robust as an actuarial measure of recidivism risk among sexual offenders in Sweden, both procedures may need further evaluation, for example, with sex offender subpopulations differing ethnically or with respect to offense characteristics. The usefulness of actuarial methods for the assessment of sex offender recidivism risk is discussed in the context of current practice.

  12. A theoretical model of the evolution of actuarial senescence under environmental stress

    Free-living organisms are exposed to a wide range of stressors, all of which can disrupt components of stress-related and detoxification physiology. The subsequent accumulation of somatic damage is widely believed to play a major role in the evolution of senescence. Organisms have evolved sophisticated physiological regulatory mechanisms to maintain homeostasis in response to environmental perturbations, but these systems are likely to be constrained in their ability to optimise robustness to multiple stressors due to functional correlations among related traits. While evolutionary change can accelerate due to human ecological impacts, it remains to be understood how exposure to multiple environmental stressors could affect senescence rates and subsequently population dynamics and fitness. We used a theoretical evolutionary framework to quantify the potential consequences for the evolution of actuarial senescence in response to exposure to simultaneous physiological stressors – one versus multiple and additive versus synergistic – in a hypothetical population of avian “urban adapters”. In a model in which multiple stressors have additive effects on physiology, species may retain greater capacity to recover, or respond adaptively, to environmental challenges. However, in the presence of high synergy, physiological dysregulation suddenly occurs, leading to a rapid increase in age-dependent mortality and subsequent population collapse. Our results suggest that, if the synergistic model is correct, population crashes in environmentally-stressed species could happen quickly and with little warning, as physiological thresholds of stress resistance are overcome.

  13. Accuracy of actuarial procedures for assessment of sexual offender recidivism risk may vary across ethnicity.

    PubMed

    2004-04-01

    Little is known about whether the accuracy of tools for assessment of sexual offender recidivism risk holds across ethnic minority offenders. I investigated the predictive validity across ethnicity for the RRASOR and the Static-99 actuarial risk assessment procedures in a national cohort of all adult male sex offenders released from prison in Sweden 1993-1997. Subjects ordered out of Sweden upon release from prison were excluded and remaining subjects (N = 1303) divided into three subgroups based on citizenship. Eighty-three percent of the subjects were of Nordic ethnicity, and non-Nordic citizens were either of non-Nordic European (n = 49, hereafter called European) or African Asian descent (n = 128). The two tools were equally accurate among Nordic and European sexual offenders for the prediction of any sexual and any violent nonsexual recidivism. In contrast, neither measure could differentiate African Asian sexual or violent recidivists from nonrecidivists. Compared to European offenders, AfricanAsian offenders had more often sexually victimized a nonrelative or stranger, had higher Static-99 scores, were younger, more often single, and more often homeless. The results require replication, but suggest that the promising predictive validity seen with some risk assessment tools may not generalize across offender ethnicity or migration status. More speculatively, different risk factors or causal chains might be involved in the development or persistence of offending among minority or immigrant sexual abusers.

  14. The ethical implications of Paul Meehl's work on comparing clinical versus actuarial prediction methods.

    Dawes, Robyn M

    2005-10-01

    Paul E. Meehl's work comparing statistical versus actuarial prediction-and the large body of research that followed by others on the same topic-was mainly theoretical and empirical. Meehl also suggested that this work led to a "practical" conclusion, which was quite strong. The author argues that, in addition, it leads to an ethical conclusion, equally strong. Whether the scientific findings are combined with an overarching ethical principle that the best predictions possible should be made for clients, or whether these findings are framed as delineating what can be done for clients-and that clinicians ought not to attempt to do what they cannot-the conclusion is the same. Whenever statistical prediction rules (SPR's) are available for making a relevant prediction, they should be used in preference to intuition. Any modification of these rules should be systematic and subject to the same type of evaluation originally used to assess the SPR's themselves. It is even possible to develop near-optimal rules in new situations. Providing service that assumes that clinicians "can do better" simply based on self-confidence or plausibility in the absence of evidence that they can actually do so is simply unethical.

    Age at release has become an increasing focus of study with regard to evaluating risk in the sex offender population and has been repeatedly shown to be an important component of the risk assessment equation. This study constitutes an extension of a study of sex offender outcomes prepared for the Evaluation Branch, Correctional Service of Canada. The entire cohort of 2,401 male federally incarcerated sexual offenders who reached their warrant expiry date (WED) within 1997/1998, 1998/1999, and 1999/2000 fiscal years were reviewed for the study. Sexual and violent reconviction information was obtained from CPIC criminal records over an average of 12.0 years (SD = 1.7) follow-up. This study focused upon the cohort of sex offenders who were 50 years or older at time of release (N = 542). They were stratified according to risk using a brief actuarial scale (BARS) comprising six binary variables. For the most part, older offenders showed low base rates of sexual recidivism regardless of the risk band into which they fell. The exception was a small group of elderly offenders (n = 20) who fell into the highest risk band, and who showed high levels of sexual recidivism. The results of this combination of cross-sectional and longitudinal analyses of elderly sexual offenders may have important implications for offender management, particularly in light of the increasing numbers of offenders in Canada who fall into the over 50 age cohort.

    Carcinogenicity of ethyl tertiary-butyl ether (ETBE) was examined with inhalation exposure using F344/DuCrlCrlj rats. Groups of 50 male and 50 female rats, 6 week old at commencement, were exposed to ETBE at 0, 500, 1,500 or 5,000 ppm (v/v) in whole-body inhalation chambers for 6 h/day, 5 days/week for 104 weeks. A significant increase in the incidence of hepatocellular adenomas was indicated in males exposed at 5,000 ppm, but not in females at any concentration. In addition, significantly increased incidences of eosinophilic and basophilic cell foci were observed in male rats at 5,000 ppm. Regarding non-neoplastic lesions, rat-specific changes were observed in kidney, with an increase in the severity of chronic progressive nephropathy in both sexes at 5,000 ppm. Increased incidences of urothelial hyperplasia of the pelvis were observed at 1,500 ppm and above, and mineral deposition was apparent in the renal papilla at 5,000 ppm in males. There were no treatment-related histopathological changes observed in any other organs or tissues in either sex. The present 2-year inhalation study demonstrated hepatotumorigenicity of ETBE in male, but not in female rats.

    Purpose Type and incidence of adverse events and rate of discontinuations for 2 years of daily wear with silicone hydrogel contact lenses in Chinese children with myopia. Methods Two hundred forty children aged 7 to 14 years were enrolled in a prospective randomized clinical trial from November 2008 to April 2009. Children with myopia of up to −3.50 diopters (D) spherical equivalent with astigmatism less than or equal to −0.75 D were randomized to one commercial and three experimental lens designs of Lotrafilcon B silicone hydrogel lenses (four groups) used bilaterally on a daily wear, monthly replacement schedule. The main outcome measures were incidence per 100 patient-years (incidence, in percentage) of adverse events and rate of discontinuations. Results There were no events of microbial keratitis. Fifty-five adverse events (incidence, 14.2%) were seen. There were also 12 recurrent events. The type and incidence percentage were contact lens papillary conjunctivitis (16 events, 4.1%), superior epithelial arcuate lesions (SEALs, six events, 1.5%), corneal erosions (eight events, 2.1%), infiltrative keratitis (five events, 1.3%), asymptomatic infiltrative keratitis (seven events, 1.8%), and asymptomatic infiltrates (13 events, 3.42%). There were differences in the incidence of SEALs between groups (p = 0.023), with the incidence of SEALs being greater with one of the experimental designs. No event resulted in any vision loss. Seventy participants (29.2%) discontinued, with one-third (26 participants, 10.8%) occurring in the first month of lens wear. Discomfort and non–lens-related reasons such as safety concern and disinterest were frequently cited reasons for discontinuations. Conclusions Adverse events with daily wear of silicone hydrogels in children were mainly mechanical in nature, and significant infiltrative events were few. The large number of dropouts in the early days of lens wear and their reasons for discontinuation suggest that adaptation and

    Children with traumatic brain injury (TBI) are at risk of social impairment, but research is yet to document the trajectory of these skills post-injury and factors that may predict social problems. The study addressed these gaps in knowledge, reporting on findings from a prospective, longitudinal follow-up study which investigated social outcomes post injury and explored factors contributing to these outcomes at 2 years post-injury. The sample included 113 children, 74 with TBI and 39 typically developing (TD) controls. TBI participants were recruited on presentation to hospital. Parents rated pre-injury function at that time and all children underwent magnetic resonance imaging (MRI) scan. Participants were followed up at 2 years post-injury. Outcomes were social adjustment, social participation, social relationships, and social cognition. Predictors of social outcomes examined included brain lesion characteristics, child cognition (6 months post-TBI) and behavior and environmental factors (pre-injury and 2 years). Reduced social adjustment (p=.011) and social participation (p<.001) were evident in children with TBI compared to TD controls. Poor social adjustment was predicted by externalizing behaviour problems and younger age at injury. Reduced social participation was linked to internalizing behavior problems. Greater lesion volume, lower socioeconomic status and family burden contributed to poorer social relationships, while age at injury predicted social cognition. Within the TBI group, 23% of children exhibited social impairment: younger age at injury, greater pre-injury and current behavior problems and family dysfunction, poorer IQ, processing speed, and empathy were linked to impairment. Further follow-up is required to track social recovery and the influences of cognition, brain, and environment over time.

    A useful understanding of the relationship between age, actuarial scores, and sexual recidivism can be obtained by comparing the entries in equivalent cells from "age-stratified" actuarial tables. This article reports the compilation of the first multisample age-stratified table of sexual recidivism rates, referred to as the "multisample age-stratified table of sexual recidivism rates (MATS-1)," from recent research on Static-99 and another actuarial known as the Automated Sexual Recidivism Scale. The MATS-1 validates the "age invariance effect" that the risk of sexual recidivism declines with advancing age and shows that age-restricted tables underestimate risk for younger offenders and overestimate risk for older offenders. Based on data from more than 9,000 sex offenders, our conclusion is that evaluators should report recidivism estimates from age-stratified tables when they are assessing sexual recidivism risk, particularly when evaluating the aging sex offender.

    This report is a description of a developing phonological system as manifested in the productions of a prelingually deafened child approximately 2 years after fitting with a Nucleus 22-Channel Multi-Electrode Cochlear Implant. A probe list consisting of 23 proper nouns familiar to the child was used to elicit samples of her speech; stimulus materials consisted of photographs of those persons (friends and family members) whose names were included in the probe list. Analysis of the child's productions addressed the composition of the phonetic inventory of consonants and vowels and the presence of syllable structure and other phonotactic constraints. Results indicated a rich inventory of speech sound segments (among both consonants and vowels) and a lack of stringent constraints on syllable structure and consonants permitted in specified word positions. A further comparative analysis of correspondences with the ambient language showed a number of patterns that are also common in the speech of children with normal hearing. PMID:22091697

    This is a retrospective study of 55 children under the age of 2 years diagnosed with Langerhans cell histiocytosis (LCH). They were classified according to age and organ function and dysfunction following Lahey's criteria. The studied population was divided into four groups by age of diagnosis (0-6, 7-12, 13-18, and 19-24 months). Statistical analysis showed no significant difference in outcome between age groups, although the population under 6 months had a 81.3% fatality rate. The presence of organ dysfunction was a major cause of death in all age groups, being statistically significant in outcome (P > 0.005) compared with patients without organ dysfunction. The presence of thrombocytopenia and/or respiratory dysfunction was also highly associated with a fatal outcome. In the surviving population, no second malignancies have been reported. The late secondary effects of therapy include endocrine, orofacial, and osseous pathologies.

    Screening with portable echocardiography has uncovered a large burden of latent rheumatic heart disease (RHD) among asymptomatic children in endemic regions, the significance of which remains unclear. This study aimed to determine the 2-year outcomes for children with latent RHD diagnosed by echocardiographic screening. Children identified with latent RHD enrolled in a biannual follow-up program. Risk factors for disease persistence and progression were examined. Of 62 children, 51 (82 %) with latent RHD had a median follow-up period of 25 months. Of these 51 children, 17 (33.3 %) reported an interval sore throat or symptoms consistent with acute rheumatic fever (ARF). Of 43 children initially classified as having borderline RHD, 21 (49 %) remained stable, 18 (42 %) improved (to no RHD) and 4 (10 %) worsened to definite RHD. Of the 8 children initially classified as having definite RHD, 6 (75 %) remained stable, and 2 (25 %) improved to borderline RHD. Two children had confirmed episodes of recurrent ARF, one of which represented the sole case of clinical worsening. The risk factors for disease persistence or progression included younger age (p = 0.05), higher antistreptolysin O titers at diagnosis (p = 0.05), and more morphologic valve abnormalities (p = 0.01). After 2 years, most of the children had a benign course, with 91 % remaining stable or showing improvement. Education may improve recognition of streptococcal sore throat. Longer-term follow-up evaluation, however, is warranted to confirm disease progression and risk factor profile. This could help tailor screening protocols for those at highest risk.

    OBJECTIVE--To determine the incidence and prognosis of congenital aortic valve stenosis in the five Health Districts of Liverpool that make up the Merseyside area. DESIGN--The records of the Liverpool Congenital Malformations Registry and the Royal Liverpool Children's Hospital identified 239 patients (155 male, 84 female) born with aortic valve stenosis between 1960 and 1990. Patients were traced to assess the severity of stenosis at follow up. Information on the severity at presentation and all subsequent events was obtained. RESULTS--Congenital aortic valve stenosis occurred in 5.7% of patients with congenital heart disease born in the Merseyside area. The median age at presentation was 16 months (range 0-20 years). Stenosis was mild at presentation in 145 patients, moderate in 33, severe in one and critical in 21 and 39 had a bicuspid valve without stenosis. Additional cardiac lesions were significantly more common in children presenting under one year of age and in those with critical stenosis. The median duration of follow up was 9.2 years (range 1-28 years) and seven patients were lost to follow up. 81 operations were performed in 60 patients. The reoperation rate was 28.3% after a median duration of 8.7 years (range 2.5-18 years). 15% of patients who presented with mild stenosis subsequently required operation compared with 67% of those with moderate stenosis. There were no sudden unexpected deaths and no deaths after aortic valvotomy, except in those presenting with critical stenosis. Mortality was 16.7% but patients presenting with critical aortic stenosis had a much worse prognosis. Actuarial and hazard analysis showed that the survival and absence of serious events (aortic valve surgery or balloon dilatation, endocarditis, or death) were significantly better in patients who presented with mild aortic stenosis than in those who presented with moderate aortic stenosis. 75% of patients presenting with mild stenosis had not progressed to moderate stenosis

    The role of 2-year colleges (2YCs) in geoscience education is growing as the number of students enrolled in Earth and space science courses increases and as these institutions—which include community colleges and junior colleges—provide more students majoring in geoscience at public universities. In recognition of the increasing role of 2YCs in geoscience education, the National Association of Geoscience Teachers (NAGT) recently created a Geo2YC division for faculty, administrators, graduate students, and other geoscience professionals who share a professional interest in geoscience education at 2YCs. The mission of the new division, which is NAGT's first national division, is to serve as a forum for exchanging curricular ideas, concerns, and resources; establish a network of geoscience educators at 2YCs and other institutions with shared interests; sponsor NAGT 2YC activities and make recommendations to the NAGT Council in support of 2YC geoscience education; support and coordinate research on 2YC geoscience education; and advocate for 2YC geoscience education within NAGT and with other organizations.

    Atopic dermatitis (AD) is a common eczematous skin condition; as many as 10-17 percent of all children are affected, and 35-60 percent of affected patients manifest symptoms manifest during the first year of life. Treatment principles for AD in young children involve conservative measures such as avoidance of hot water and environmental irritants, combined with liberal use of emollients after bathing. Low potency topical corticosteroids (TCS) are the current standard of therapy for AD in young children, reserving mid- and high-potency TCS for severe disease. However, complications of long-term use of TCS include skin atrophy, stria formation, telangiectasia, hypopigmentation, secondary infections, steroid acne, allergic contact dermatitis, and miliaria. The pediatric population is also at increased risk for systemic absorption because of their high ratio of skin surface to body mass. Systemic absorption may result in hypothalamic-pituitary-adrenal axis suppression and ultimately growth retardation. Although most topical and systemic corticosteroids are not approved by the Food and Drug Administration for use in children less than 2 years of age, conservative treatment often fails in this age group and frequently patients are treated with TCS, antibiotics, and antihistamines.

    An actuarial assessment to predict male-to-female marital violence was constructed from a pool of potential predictors in a sample of 589 offenders identified in police records and followed up for an average of almost 5 years. Archival information in several domains (offender characteristics, domestic violence history, nondomestic criminal history, relationship characteristics, victim characteristics, index offense) and recidivism were subjected to setwise and stepwise logistic regression. The resulting 13-item scale, the Ontario Domestic Assault Risk Assessment (ODARA), showed a large effect size in predicting new assaults against legal or common-law wives or ex-wives (Cohen's d = 1.1, relative operating characteristic area =.77) and was associated with number and severity of new assaults and time until recidivism. Cross-validation and comparisons with other instruments are also reported.

    2005-02-01

    Approximately 10% of all hospital admissions are complicated by critical incidents in which harm is caused to the patient - this amounts to more than 850,000 incidents annually. Critical incident reporting (CIR) systems refer to the structured reporting, collation and analysis of such incidents. This article describes the attributes required for an effective CIR system. Example neonatal trigger events and a management pathway for handling a critical incident report are described. The benefits and limitations of CIR systems, reactive and prospective approaches to the analysis of actual or potential critical incidents and the assessment of risk are also reviewed. Individual human error is but one contributor in the majority of critical incidents. Recognition of this and the fostering of an organisational culture that views critical incident reports as an opportunity to learn and to improve future patient care is vital if CIR systems are to be effective.

    The SMOS (Soil Moisture and Ocean Salinity) satellite was successfully launched in November 2009. This ESA led mission for Earth Observation is dedicated to provide soil moisture over continental surface (with an accuracy goal of 0.04 m3/m3) and ocean salinity. These two geophysical features are important as they control the energy balance between the surface and the atmosphere. Their knowledge at a global scale is of interest for climatic and weather researches in particular in improving models forecasts. The purpose of this communication is to present the mission results after more than two years in orbit as well as some outstanding results already obtained. A special attention will be devoted to level 2 products. Modeling multi-angular brightness temperatures is not straightforward. The radiative model transfer model L-MEB (L-band Microwave Emission) is used over land while different models with different approaches as to the modeling of sea surface roughness are used over ocean surfaces. Over land the approach is based on semi-empirical relationships, adapted to different type of surface. The model computes a dielectric constant leading to surface emissivity. Surface features (roughness, vegetation) are also considered in the models. However, considering SMOS spatial resolution a wide area is seen by the instrument with strong heterogeneity. The L2 soil moisture retrieval scheme takes this into account. Brightness temperatures are computed for every classes composing a working area. A weighted function is applied for the incidence angle and the antenna beam. Once the brightness temperature is computed for the entire working area, the minimizing process starts. If no soil moisture is derived (not attempted or process failed) a dielectric constant is still derived from an simplified modeled (the cardioid model). SMOS data enabled very quickly to infer Sea surface salinity fields. As salinity retrieval is quite challenging, retrieving it enable to assess very

    Individual card records of all cows that began 1 or more lactations between the inclusive dates of Jan 1, 1976 and Dec 31, 1986 were obtained from a California dairy herd. Calving date, lactation number, physical examination date, conception date, and clinical findings pertinent to cystic ovarian disease (COD) were extracted from the records. Lactation-specific data were organized into cohorts by quarter and year in which lactation began, and the following estimates were calculated for each of the 44 cohorts: separate actuarial cumulative incidences for cows in their first lactation, cows in the second or later lactation, and all cows combined; separate proportions of the incident cases that were in their second or greater lactation and that had recurred from any previous lactation; proportions of the incident cases that had recurrence of COD 1 or more times, and recurrence 2 or more times during the lactation; and the mean number of days in lactation at diagnosis of the incident case. Time-series analysis and multiple-regression modeling procedures were used to characterize changes in the overall incidence rate over the study period and to describe the contribution of additional measures to the dynamics of the incidence rates. The quarterly actuarial cumulative incidences of COD increased concurrently with the increased incidence among cows in the second or later lactation. Neither the proportion of incident cases that were diseased during a previous lactation nor the proportion of cases that were in the second or later lactation contributed to the observed changes in the overall incidence rate.(ABSTRACT TRUNCATED AT 250 WORDS)

    In the juvenile justice system, much attention is paid to estimating the risk for recidivism among juvenile offenders. However, it is also important to estimate the risk for problematic child-rearing situations (care needs) in juvenile offenders, because these problems are not always related to recidivism. In the present study, an actuarial care needs assessment tool for juvenile offenders, the Youth Offender Care Needs Assessment Tool (YO-CNAT), was developed to predict the probability of (a) a future supervision order imposed by the child welfare agency, (b) a future entitlement to care indicated by the youth care agency, and (c) future incidents involving child abuse, domestic violence, and/or sexual norm trespassing behavior at the juvenile's address. The YO-CNAT has been developed for use by the police and is based solely on information available in police registration systems. It is designed to assist a police officer without clinical expertise in making a quick assessment of the risk for problematic child-rearing situations. The YO-CNAT was developed on a sample of 1,955 juvenile offenders and was validated on another sample of 2,045 juvenile offenders. The predictive validity (area under the receiver-operating-characteristic curve) scores ranged between .70 (for predicting future entitlement to care) and .75 (for predicting future worrisome incidents at the juvenile's address); therefore, the predictive accuracy of the test scores of the YO-CNAT was sufficient to justify its use as a screening instrument for the police in deciding to refer a juvenile offender to the youth care agency for further assessment into care needs.

    Compensating wage differentials are used to estimate marginal rates of substitution between income and both fatal and non-fatal occupational-injury risks in the Mexico City metropolitan area. Data are obtained by in-person survey of almost 600 workers and include workers' perceived risks of fatal and non-fatal occupational injury supplemented by actuarial-risk estimates from government statistics. Results using both actuarial- and perceived-risk estimates are reasonably consistent. Estimates of the value per statistical life are between 235,000 US dollars and 325,000 US dollars and estimates of the value per statistical non-fatal injury are between 3500 US dollars and 11,000 US dollars (2002 US dollars). These values are much smaller than corresponding estimates for higher-income countries but are compatible with the small number of prior estimates for lower-income countries.

    A 2-year, randomized, double-blind, placebo-controlled study in men with osteoporosis demonstrated that treatment with risedronate 35mg once a week significantly decreased bone turnover markers (BTMs) and increased bone mineral density (BMD). This study was extended to include a 2-year, open-label extension to continue to assess the safety and efficacy of risedronate in men with osteoporosis. In the open-label extension, all patients received risedronate 35mg once a week, and 1000mg elemental calcium and 400 to 500IU vitamin D daily for up to 2 years. The safety of risedronate was evaluated based on adverse events, laboratory data, vital signs, and physical examination results. BMD, BTMs, and the incidence of new vertebral fractures were also assessed. A total of 218 (of 284) patients enrolled in the open-label extension. Risedronate continued to produce significant increases in lumbar spine BMD from baseline (7.87%) in the group of patients who took it for 4 years. Risedronate produced significant increases in lumbar spine BMD from baseline (6.27%) in the former placebo group who took it for 2 years during the open-label extension. Few new vertebral and clinical fractures occurred during the study. There were no significant differences in BTMs between the two groups at months 36 and 48. Incidences of any upper GI adverse events during the extension were low and similar in the two groups; however, the percent of moderate to severe events were higher (8% versus 2%) in the group that received placebo prior to the extension. Safety results continued to show that risedronate was well-tolerated in men with osteoporosis. Patients who received risedronate 35mg once a week for 2years in the open-label extension study showed similar safety and efficacy results compared with those who received risedronate treatment in the first 2 double-blind years of the study. Patients who received risedronate for 4 years in total showed similar safety and efficacy to that observed in

    We have calculated the incidence of Menkes disease for Denmark, France, The Netherlands, the United Kingdom and West Germany, based on known Menkes patients born during the time period 1976-87. Considering live-born Menkes patients, the combined incidence for these five countries is 1 Menkes patient per 298,000 live-born babies. If the number of affected aborted fetuses are taken into account, the incidence is 1 Menkes per 254,000 live-born babies. This incidence, which is 2-4 times lower than earlier published incidence figures, places Menkes disease as an extremely rare disease. The mutation rate for Menkes disease is estimated to be 1.96 x 10(-6), based on the number of isolated Menkes cases born during the time period 1976-87 and the total number of newborn males during this time.

    There has been relatively little research on the degree to which measures of lifetime history of substance abuse add to the prediction of risk based on actuarial measures alone among sexual offenders. This issue is of relevance in that a history of substance abuse is related to relapse to substance using behavior. Furthermore, substance use has been found to be related to recidivism among sexual offenders. To investigate whether lifetime history of substance abuse adds to prediction over and above actuarial instruments alone, several measures of substance abuse were administered in conjunction with the Sex Offender Risk Appraisal Guide (SORAG). The SORAG was found to be the most accurate actuarial instrument for the prediction of serious recidivism (i.e., sexual or violent) among the sample included in the present investigation. Complete information, including follow-up data, were available for 250 offenders who attended the Regional Treatment Centre Sex Offender Treatment Program (RTCSOTP). The Michigan Alcohol Screening Test (MAST) and the Drug Abuse Screening Test (DAST) were used to assess lifetime history of substance abuse. The results of logistic regression procedures indicated that both the SORAG and the MAST independently added to the prediction of serious recidivism. The DAST did not add to prediction over the use of the SORAG alone. Implications for both the assessment and treatment of sexual offenders are discussed.

    An investigation and extension of the Risk Assessment Scale for Prison (RASP-Potosi), an actuarially derived scale for the assessment of prison violence, was undertaken through a retrospective review of the disciplinary records of the first 12 months of confinement of a cohort of inmates entering the Florida Department of Corrections in 2002 and remaining throughout 2003 (N=14,088). A near replication of the RASP-Potosi and additional analyses based on other weighted logistic regression models were performed on an inmate subsample for whom all information categories were available (n=13,341). Younger age and shorter sentences were associated with increased violent misconduct. Older age, drug conviction, and higher educational attainment were associated with reduced violent misconduct. Regardless of whether the original RASP-Potosi or its progeny were utilized, or the custody level of the inmate sample, the models were modestly successful in predicting prison violence, with the area under the curve (AUC) ranging from .645 to .707.

    We investigated the precision of individual risk estimates made using actuarial risk assessment instruments (ARAIs) by discussing some major conceptual issues and then illustrating them by analyzing new data. We used a standard multivariate statistical procedure, logistic regression, to create a new ARAI based on data from a follow-up study of 90 adult male sex offenders. We indexed predictive precision at the group level using confidence intervals for group mean probability estimates, and at the individual level using prediction intervals for individual probability estimates. Consistent with past research, ARAI scores were moderately and significantly predictive of failure in the aggregate, but group probability estimates had substantial margins of error and individual probability estimates had very large margins of error. We conclude that, without major advances in our understanding of the causes of violence, ARAIs cannot be used to estimate the specific probability or absolute likelihood of future violence with any reasonable degree of precision or certainty. The implications for conducting violence risk assessments in forensic mental health are discussed.

    For prevention purposes, it is important that police officers can estimate the risk for delinquency among juveniles who were involved in a criminal offense, but not in the role of a suspect. In the present study, the Youth Actuarial Risk Assessment Tool for First-Time Offending (Y-ARAT-FO) was developed based solely on police records with the aim to enable Dutch police officers to predict the risk for first-time offending. For the construction of this initial screening instrument, an Exhaustive Chi-squared Automatic Interaction Detector (Exhaustive CHAID) analysis was performed on a data set that was retrieved from the Dutch police system. The Y-ARAT-FO was developed on a sample of 1,368 juveniles and validated on a different sample of 886 juveniles showing moderate predictive accuracy in the validation sample (area under the receiver operating characteristic curve [AUC] = .728). The predictive accuracy of the Y-ARAT-FO was considered sufficient to justify its use as an initial screening instrument by the Dutch police.

  11. An actuarial analysis shows that offering lung cancer screening as an insurance benefit would save lives at relatively low cost.

    Lung cancer screening is not established as a public health practice, yet the results of a recent large randomized controlled trial showed that screening with low-dose spiral computed tomography reduces lung cancer mortality. Using actuarial models, this study estimated the costs and benefits of annual lung cancer screening offered as a commercial insurance benefit in the high-risk US population ages 50-64. Assuming current commercial reimbursement rates for treatment, we found that screening would cost about $1 per insured member per month in 2012 dollars. The cost per life-year saved would be below $19,000, an amount that compares favorably with screening for cervical, breast, and colorectal cancers. Our results suggest that commercial insurers should consider lung cancer screening of high-risk individuals to be high-value coverage and provide it as a benefit to people who are at least fifty years old and have a smoking history of thirty pack-years or more. We also believe that payers and patients should demand screening from high-quality, low-cost providers, thus helping set an example of efficient system innovation.

    2013-07-01

    The Risk Need Responsivity (RNR) principles (Andrews & Bonta, 2010) dictate that higher risk sex offenders should receive more intensive treatment. The present study investigates how clinically based treatment assignment relates to risk level in a sex offender sample from The Netherlands. Correlational analyses served to identify sources of mismatches: that is, variables differing significantly in their relation between treatment selection and risk level. Our study sample consisted of 194 convicted rapists and 214 convicted child molesters. All participants' criminal files were retrospectively coded in terms of the items of the STATIC-99R, PCL: SV, and SVR-20. A low to moderate correlation was observed between clinical treatment selection and actuarial risk levels. A substantial part of the sex offenders, especially child molesters, received overly intensive treatment and another substantial part, especially rapists, received treatment of lesser intensity than indicated by their risk levels. General violent and antisocial risk factors seemed to be underemphasized in the clinical evaluation of sex offenders, especially rapists. A negative attitude toward intervention was negatively associated with clinical treatment selection. It is concluded that clinical treatment selection leads to an insufficient match between risk level and treatment level and systematic use of validated structured risk assessment instruments is necessary to ensure optimal adherence to the risk principle.

    The aim of this study was to assess the effect of treatment with risedronate 5 mg daily relative to control in men with primary or secondary osteoporosis over 2 years. Osteoporosis is a common condition in men that can have serious clinical consequences. In an earlier interim report, we found that 1 year of risedronate therapy resulted in significant increases in bone mineral density (BMD) and a significant reduction in vertebral fractures compared to control in men with osteoporosis. We conducted an open-label, prospective, match-control trial on men with primary or secondary osteoporosis in a single center, outpatient setting. Men with primary or secondary osteoporosis, as defined by a baseline lumbar spine BMD T-score < or = -2.5 and a baseline femoral neck BMD T-score < or = 2.0, were eligible for this study. Patients who had been treated with bisphosphonates or fluoride within the last 12 months were excluded. A total of 316 men were randomized to risedronate (n = 158) or control (n = 158). Patients were stratified by the presence of prevalent vertebral fractures at baseline and case by case allocated to either daily treatment with risedronate 5 mg daily plus calcium (1,000 mg) and vitamin D (800 IU) or to a control group (daily alfacalcidol (1 microg) plus calcium (500 mg) for those with prevalent vertebral fractures; daily vitamin D (800 IU) plus calcium (1,200 mg) for those without previous vertebral fractures). Primary study end points were identified prior to study initiation as the incidence of new vertebral fractures and changes in BMD at the lumbar spine, femoral neck, and total hip. Other end points included incidence of nonvertebral fractures and change in body height and back pain. Compared to control, the incidence of new vertebral fractures was significantly reduced in the risedronate 5 mg daily group at 2 years [14/152 (9.2%) for risedronate vs. 35/148 (23.6%) for control (61% risk reduction; P = 0.0026)].

    The previous literature about comorbidity between eating disorders (ED) and other DSM-IV psychiatric disorders in adolescence has employed cross-sectional studies with clinical samples, where the comorbid disorders were diagnosed retrospectively. The present study aims to overcome these limitations by the analysis of comorbidity in a community population during 2-year follow-up. A semi-structured interview was applied to a teenager sample. Firstly, a cross-sectional and non-randomized study on psychiatric morbidity was conducted with 993 teenagers between the ages of 12 and 16 from five schools. Secondly, 326 students between 14 and 17 years old of one school were reassessed 2 years later in order to detect ED new cases and find associations with previous psychiatric disorders. The ED prevalence was 3.6%. Cross-sectional analysis revealed that 62.9% of individuals with an ED had comorbid disorders: anxiety disorders (51.4%), Attention Deficit Hyperactivity Disorder (31.4%), oppositional defiant disorder (11.4%), and obsessive compulsive disorder (8.6%). Prospective longitudinal analysis showed an ED incidence rate of 2.76% over the course of 2 years. 22.2% of new cases had received previous psychiatric diagnoses, of which all were anxiety disorders. Thus, ED exhibited a high comorbidity rate among adolescent populations and anxiety disorders were the most common comorbid diagnosis.

    1991-01-01

    Changes in the incidence of coelic disease was studied among children born in Göteborg, Sweden, between 1970 and 1988. A total of 188 patients with coeliac disease were found. Of these, 83% were less than 2 years old at the time of their first duodenal biopsy and 74% of them have so far been verified according to the criteria of the European Society for Gastroenterology and Nutrition (ESPGAN). The cumulative incidence at 2 years of age/1000 liveborn infants increased significantly from 0.31 in the first birth cohort to 2.93 in the last. This increase could only partly be explained by improvements in detection. Weight for age at diagnosis was generally considerably below the reference value, but was slightly less affected towards the end of the period. The increase in incidence of coeliac disease is the first reported since the middle 1970s and makes the disease one of the most common chronic diseases among Swedish children. PMID:2039251

    This study sought to examine the association between the parent-reported appetite of a child and the child's weight status after 2 years. The design was a 2-year prospective study. A total of 531 Korean children aged 11 to 12 years were followed up for change in weight status (persistent overweight, persistent nonoverweight, recently overweight, recently nonoverweight) between 2001 and 2003 after the measurement of their appetite (low, moderate, and high) using a questionnaire administered to their parents in 2001. Weight status of each child was determined based on the criteria of body mass index (BMI) recommended by the International Obesity Task Force reference. The statistical analyses performed were multiple logistic regression analysis with adjustment for parental factors (parents' weight and height, education level, and income) and the child's characteristics (baseline BMI, physical activity, and television viewing). Main outcome measures were child's mean BMI and weight status, and the proportions of overweight children at the baseline and at the end of the follow-up were greater among those children whose parents reported that they had high appetites (P<0.001). Compared with the children with a low appetite, the odds ratio for overweight at the end of follow-up was 3.7 (95% confidence interval 1.2 to 11.7) in children with a high appetite. Subgroup analysis of overweight children at baseline showed that the risk of being persistently overweight over the 2-year follow-up was 5.5 times (95% confidence interval 1.1 to 27.5) higher in children with a high appetite than in those with a low appetite. There was a strong association between the parent-reported appetite of a child and being overweight after 2 years. Identifying children with higher appetites and targeting them for lifestyle modification may provide an effective way of reducing the incidence of childhood overweight.

    Objective Estimate age-specific incidence of endometrial hyperplasia: simple, complex, and atypical, in order of increasing likelihood of progression to carcinoma. Study design Women ages 18–90 years with endometrial pathology specimens (1985–2003) at a large integrated health plan were identified using automated data. Incidence rates were obtained by dividing the number of cases by the estimated number of female health plan enrollees who retained a uterus. Results Endometrial hyperplasia peak incidence was: simple-142/100,000 woman-years, complex-213/100,000 woman-years, both in the early 50s; and atypical-56/100,000 woman-years in the early 60s. Age-adjusted incidence decreased over the study period, especially for atypical hyperplasia. Conclusions Endometrial hyperplasia incidence without and with atypia peaks in the early postmenopausal years and in the early 60s, respectively. Given that some cases of endometrial hyperplasia likely go undiagnosed, the figures provided should be viewed as minimum estimates of the true incidence. PMID:19393600

    A traditional view of incidents is that they are caused by shortcomings in human competence, attention, or attitude. It may be under the label of “loss of situational awareness,” procedure “violation,” or “poor” management. A different view is that human error is not the cause of failure, but a symptom of failure – trouble deeper inside the system. In this perspective, human error is not the conclusion, but rather the starting point of investigations. During an investigation, three types of information are gathered: physical, documentary, and human (recall/experience). Through the causal analysis process, apparent cause or apparent causes are identified as the most probable cause or causes of an incident or condition that management has the control to fix and for which effective recommendations for corrective actions can be generated. A causal analysis identifies relevant human performance factors. In the following presentation, the anatomy of a radiological incident is discussed, and one case study is presented. We analyzed the contributing factors that caused a radiological incident. When underlying conditions, decisions, actions, and inactions that contribute to the incident are identified. This includes weaknesses that may warrant improvements that tolerate error. Measures that reduce consequences or likelihood of recurrence are discussed.

    We estimated age-specific herpes zoster (HZ) incidence rates in the Kaiser Permanente Northwest Health Plan (KPNW) during 1997-2002 and tested for secular trends and differences between residents of two states with different varicella vaccine coverage rates. The cumulative proportions of 2-year-olds vaccinated increased from 35% in 1997 to 85% in 2002 in Oregon, and from 25% in 1997 to 82% in 2002 in Washington. Age-specific HZ incidence rates in KPNW during 1997-2002 were compared with published rates in the Harvard Community Health Plan (HCHP) during 1990-1992. The overall HZ incidence rate in KPNW during 1997-2002 (369/100,000 person-years) was slightly higher than HCHP's 1990-1992 rate when adjusted for age differences. For children 6-14 years old, KPNW's rates (182 for females, 123 for males) were more than three times HCHP's rates (54 for females, 39 for males). This increase appears to be associated with increased exposure of children to oral corticosteroids. The percentage of KPNW children exposed to oral corticosteroids increased from 2.2% in 1991 to 3.6% in 2002. Oregon residents had slightly higher steroid exposure rates during 1997-2002 than Washington residents. There were significant increases in HZ incidence rates in Oregon and Washington during 1997-2002 among children aged 10-17 years, associated with increased exposure to oral steroids. PMID:15816149

    Think about an asteroid smashing into the surface of the Moon and excavating a crater; or hitting Earth and scattering meteorite fragments over a strewn field. Imagine a fragment of cometary dust burning out in the Earth's atmosphere and producing a meteor. These bodies have paths that are inclined at some angle to the vertical. But what is the predominant value of this angle of incidence, i? How does the number of incident bodies vary as a function of angle i? And how do both these affect the prevalence of non- circular lunar craters and the ellipticity of meteorite strewn fields?

    were no serious adverse events (SAE), and the numbers of mild-to-moderate adverse events (AE) were not different between groups. Despite the higher initial fracture risk in the alfacalcidol group, 2-year treatment with this active D-hormone prodrug showed a higher therapeutic efficacy in terms of BMD, falls and fractures. One important advantage of alfacalcidol may be that it is effective even in patients with mild-to-moderate renal insufficiency.

    Leptospirosis is endemic in Southeast Asia, Central and South America, the Caribbean, and Oceania. Malaysia was categorized as a probable endemic country without any available data. Thus, this study was conducted to determine incidence, case fatality rate and mortality rate of leptospirosis. Leptospirosis is a notifiable disease in Malaysia since 2010 whereby probable or confirmed cases must be notified to relevant health district office. There were 3,665 and 4,457 probable and laboratory confirmed leptospirosis cases notified in 2012 and 2013, respectively. In the 2-year period, the most common age group of patients was 19 years old or less (23.3%) with male:female ratio of 2.61:1. Students consisted about 16.9% of patients, followed by agriculture-based or plantation workers (14.7%). Overall age-standardized incidence rate of leptospirosis in Malaysia for 2012 and 2013 was 29.02 per 100,000. Overall case fatality rate was 1.47% for 2-year period and overall age-standardized mortality rate was 0.45 per 100,000. Leptospirosis is an emerging public health concern in Malaysia and may pose a significant health impact and burden to the nation in the coming years if not well controlled.

  8. New model for predicting freeway incidents and incident delays

    SciTech Connect

    Sullivan, E.C.

    1997-08-01

    This paper presents a new model that predicts the number of freeway incidents and associated delays based on general freeway segment characteristics, traffic volumes, and incident management procedures. The model is intended to be used in planning capacity-enhancing freeway improvements and incident management programs. Estimates of incident frequencies, severity, durations, and delays are provided for seven standard incident types, each of which represents a significant fraction of total unplanned incidents and has severity and/or duration characteristics substantially different from the others. In addition to describing the incident prediction model, the paper addresses the need for a coordinated national strategy for collecting incident data, with particular attention to urban freeways. It concludes that the incident data systems that have evolved in several urban areas, often in connection with freeway service patrols and incident response team activities, already provide a valuable nationwide data resource for understanding incident patterns and their variations. However, better national coordination of locally collected incident data would be helpful for addressing issues beyond the scope of the local concerns for which virtually all current systems were originally designed. Specific areas for improvement include the definitions of incident types, descriptions of incident locations (relative to both the length and breadth of the highway), and data recording the critical times during incidents such as when detection, response, and clearing occur.

    Abstract Smoking is a serious global public health concern that has been related to many chronic diseases. However, the effect of smoking on eye disorders has been less studied. The aim of this cohort study was to assess the association between current tobacco smokers and the risk of developing glaucoma and furthermore to evaluate the relationship between passive or former smokers and glaucoma. In this prospective and dynamic cohort, 16,797 participants initially who were found not to have glaucoma were followed up for a median of 8.5 years. Validated data on lifestyle, including tobacco consumption, were assessed at baseline. Information about new diagnosis of glaucoma was collected by follow-up questionnaires every 2 years. The outcome was the incidence of self-reported glaucoma during the follow-up. A subsample was used to validate the glaucoma diagnosis. During the 8.5 years of follow-up, 184 new glaucoma cases were identified. Current smokers had a significantly higher risk of glaucoma compared to participants who had never smoked after controlling for potential confounders (Hazard ratio [HR] 1.88 [95% coefficient interval (CI): 1.26–2.81]; P = 0.002). A nonsignificant increased risk was found among former smokers (HR 1.27 [95% CI: 0.88–1.82]; P = 0.198). When we assessed the exposure as per the number of cigarette pack-years, a dose–response relationship between pack-years and the risk of glaucoma was found (HR for the 5th quintile versus the 1st quintile: 1.70 [95% IC: 1.10–2.64], P for trend, 0.009). However, no relationship was found between passive smokers and glaucoma. (HR 0.67 [95% CI: 0.37–1.21]; P = 0.189). Our results suggest a direct association between current smokers and the incidence of glaucoma. In particular, this association was related to the number of pack-years, which was not found in the case of former smokers nor in the case of passive smokers. PMID:28072720

    Constipation is one of the most prevalent conditions in primary care settings and increases the risk of cardiovascular disease, potentially through processes mediated by altered gut microbiota. However, little is known about the association of constipation with CKD. In a nationwide cohort of 3,504,732 United States veterans with an eGFR ≥60 ml/min per 1.73 m(2), we examined the association of constipation status and severity (absent, mild, or moderate/severe), defined using diagnostic codes and laxative use, with incident CKD, incident ESRD, and change in eGFR in Cox models (for time-to-event analyses) and multinomial logistic regression models (for change in eGFR). Among patients, the mean (SD) age was 60.0 (14.1) years old; 93.2% of patients were men, and 24.7% were diabetic. After multivariable adjustments, compared with patients without constipation, patients with constipation had higher incidence rates of CKD (hazard ratio, 1.13; 95% confidence interval [95% CI], 1.11 to 1.14) and ESRD (hazard ratio, 1.09; 95% CI, 1.01 to 1.18) and faster eGFR decline (multinomial odds ratios for eGFR slope <-10, -10 to <-5, and -5 to <-1 versus -1 to <0 ml/min per 1.73 m(2) per year, 1.17; 95% CI, 1.14 to 1.20; 1.07; 95% CI, 1.04 to 1.09; and 1.01; 95% CI, 1.00 to 1.03, respectively). More severe constipation associated with an incrementally higher risk for each renal outcome. In conclusion, constipation status and severity associate with higher risk of incident CKD and ESRD and with progressive eGFR decline, independent of known risk factors. Further studies should elucidate the underlying mechanisms.

    This article is an evaluation of established actuarial probation-parole tests in light of new data on violent and homicidal behavior. Probation-parole tests originally were developed by observing risks related with recidivism or return to court after release (i.e., the "danger" of releasing an individual) by following offenders in court records for up to 10 years. Commonly used probation-parole tests together comprise 82 distinct items related to characteristics of the offender: home, school, peers, job, family, individual-medical, community, and court contacts. The risks for violence and homicide found by Zagar, et al. were compared with prior meta-analyses of risks with the criterion of violent delinquency. Bootstrapped logistic regressions in Zagar and colleagues' new data yielded highly accurate predictions of violence, showing that improved methods and sampling can lead to still higher accuracy than had been achieved by established probation-parole tests. A general discussion of the usefulness of actuarial tests and answers to challenges of their validity for decision making are provided.

    A Grazing Incidence Beam Expander (GIBE) telescope is being designed and fabricated to be used as an equivalent end mirror in a long laser resonator cavity. The design requirements for this GIBE flow down from a generic Free Electron Laser (FEL) resonator. The nature of the FEL gain volume (a thin, pencil-like, on-axis region) dictates that the output beam be very small. Such a thin beam with the high power levels characteristic of FELs would have to travel perhaps hundreds of meters or more before expanding enough to allow reflection from cooled mirrors. A GIBE, on the other hand, would allow placing these optics closer to the gain region and thus reduces the cavity lengths substantially. Results are presented relating to optical and mechanical design, alignment sensitivity analysis, radius of curvature analysis, laser cavity stability analysis of a linear stable concentric laser cavity with a GIBE. Fabrication details of the GIBE are also given.

    As survival rates have risen for children with malignant primary brain tumors, so has the concern that many survivors have significant permanent cognitive deficits. Cranial irradiation (CRT) has been implicated as the major cause for cognitive dysfunction. To clarify the etiology, incidence, and severity of intellectual compromise in children with brain tumors after CRT, a prospective study was undertaken comparing the neuropsychological outcome in 18 consecutive children with malignant brain tumors treated with CRT to outcome in 14 children harboring brain tumors in similar sites in the nervous system who had not received CRT. Children with cortical or subcortical brain tumors were not eligible for study. Neuropsychological testing was performed after surgery prior to radiotherapy, after radiotherapy, and at 1- and 2-year intervals thereafter. Children who had received CRT had a mean full-scale intelligence quotient (FSIQ) of 105 at diagnosis which fell to 91 by Year 2. Similar declines were noted in their performance intelligence quotient (IQ) and verbal IQ. After CRT, patients demonstrated a statistically significant decline from baseline in FSIQ (p less than 0.02) and verbal IQ (p less than 0.04). Children who had not received CRT did not demonstrate a fall in any cognitive parameter over time. The decline between baseline testing and testing performed at Year 2 in patients who had CRT was inversely correlated with age (p less than 0.02), as younger children demonstrated the greatest loss of intelligence. Children less than 7 years of age at diagnosis had a mean decline in FSIQ of 25 points 2 years posttreatment. No other clinical parameter correlated with the overall IQ or decline in IQ. After CRT, children demonstrated a wide range of dysfunction including deficits in fine motor, visual-motor, and visual-spatial skills and memory difficulties.

    Perfluorooctanoate (PFO) is a perfluorinated carboxylate that is widely distributed in the environment. A 2-year chronic study was conducted in rats fed either 30 or 300 ppm of ammonium perfluorooctanoate (APFO). To investigate the possible relationship of APFO exposure to proliferative mammary lesions, a Pathology Working Group (PWG) review of the original slides was performed. The consensus reached by the PWG was that the incidence of mammary-gland neoplasms was not affected by chronic dietary administration of APFO. Therefore, feeding female rats up to 300 ppm of APFO resulted in no increase in proliferative lesions of the mammary tissue.

Results Among the 402 males and 450 females in the cohort, mean weight-for-age Z-score (WAZ) declined from -0.67 ± 1.01 at 1 year to -1.07 ± 0.87 at 2 years, while mean height-for-age Z-score (HAZ) declined from -1.88 ± 1.19 at 1 year to -2.37 ± 0.99 at 2 years. Using multiple linear regression modeling, number of children <5 years old, vomiting in the past week, fever in the past week, and WAZ at 1 year were significant predictors of WAZ at 2 years. Significant predictors of HAZ at 2 years included household size, number of children <5 years old, diarrhea in the past week, WAZ at 1 year, and HAZ at 1 year. Vomiting in the past week and WAZ at 1 year were significant predictors of weight-for-height z-score (WHZ) at 2 years. Conclusions Number of children <5 years old, symptoms such as vomiting or diarrhea in the previous week, and prior nutritional status were the most significant predictors of malnutrition in this cohort. Future research may focus on the application of models to develop predictive algorithms for mobile device technology, as well as the identification of other predictors of malnutrition that are not well characterized such as the interaction of environmental exposures with protein consumption and epigenetics.

    Despite seclusion being described as one of the most ethically- and legally-controversial management options available, it remains a widely-used clinical strategy for managing disruptive, aggressive, and violent behaviour. This study sought to determine how frequently seclusion was used, the common characteristics of those secluded and not secluded, and the degree to which the Level of Service Inventory - Revised: Screening Version (LSI-R: SV) could predict seclusion. The study was retrospective, covering the first 2 years of operation of a statewide forensic psychiatry hospital in Victoria, Australia. Data were collected from individual case files, electronic databases, and paper copies of records pertaining to violent incidents and episodes of seclusion. Eighty five (44%) of the 193 patients admitted during this period were secluded. Those secluded were significantly younger and had a more established psychiatric history. LSI-R: SV scores were significantly and positively associated with being secluded. A statistical model containing three LSI-R: SV items, along with age on admission and psychiatric history, achieved an area under the curve of 0.74. Seclusion is used on a regular basis in response to a range of different forms of aggressive behaviour of different severity. The LSI-R: SV demonstrated moderate-to-good accuracy in predicting seclusion and warrants further research using detailed prospective methodologies.

    2015-01-01

    Objective: To investigate the relation between baseline cerebral small vessel disease (SVD) and the risk of incident parkinsonism using different MRI and diffusion tensor imaging (DTI) measures. Methods: In the Radboud University Nijmegen Diffusion Tensor and Magnetic Resonance Cohort (RUN DMC) study, a prospective cohort study, 503 elderly participants with SVD and without parkinsonism were included in 2006. During follow-up (2011–2012), parkinsonism was diagnosed according to UK Brain Bank criteria. Cox regression analysis was used to investigate the association between baseline imaging measures and incident all-cause parkinsonism and vascular parkinsonism (VP). Tract-based spatial statistics analysis was used to identify differences in baseline DTI measures of white matter (WM) tracts between participants with VP and without parkinsonism. Results: Follow-up was available from 501 participants (mean age 65.6 years; mean follow-up duration 5.2 years). Parkinsonism developed in 20 participants; 15 were diagnosed with VP. The 5-year risk of (any) parkinsonism was increased for those with a high white matter hyperintensity (WMH) volume (hazard ratio [HR] 1.8 per SD increase, 95% confidence interval [CI] 1.3–2.4) and a high number of lacunes (HR 1.4 per number increase, 95% CI 1.1–1.8) at baseline. For VP, this risk was also increased by the presence of microbleeds (HR 5.7, 95% CI 1.9–16.8) and a low gray matter volume (HR 0.4 per SD increase, 95% CI 0.2–0.8). Lower fractional anisotropy values in bifrontal WM tracts involved in movement control were observed in participants with VP compared to participants without parkinsonism. Conclusions: SVD at baseline, especially a high WMH volume and a high number of lacunes, is associated with incident parkinsonism. Our findings favor a role of SVD in the etiology of parkinsonism.

    Objective. To evaluate the degree of axial elongation with soft radial refractive gradient (SRRG) contact lenses, orthokeratology (OK), and single vision (SV) spectacle lenses (control) during a period of 1 year before treatment and 2 years after treatment. Methods. This was a prospective, longitudinal, nonrandomized study. The study groups consisted of 30, 29, and 41 children, respectively. The axial length (AL) was measured during 2 years after recruitment and lens fitting. Results. The baseline refractive sphere was correlated significantly (Spearman's Rho (ρ) correlation = 0.542; P < 0.0001) with the amount of myopia progression before baseline. After 2 years, the mean myopia progression values for the SRRG, OK, and SV groups were −0.56 ± 0.51, −0.32 ± 0.53, and −0.98 ± 0.58 diopter, respectively. The results represent reductions in myopic progression of 43% and 67% for the SRRG and OK groups, respectively, compared to the SV group. The AL increased 27% and 38% less in the SRRG and OK groups, respectively compared with the SV group at the 2-year visit (P < 0.05). Axial elongation was not significantly different between SRRG and OK (P = 0.430). Conclusion. The SRRG lens significantly decreased AL elongation compared to the SV control group. The SRRG lens was similarly effective to OK in preventing myopia progression in myopic children and adolescent. PMID:26605331

    This longitudinal study examines to what extent different depressive and anxiety disorders and clinical characteristics are associated with subsequent weight change, while controlling for baseline weight, sociodemographics, health status, psychotropic medication use and (un)healthy lifestyle factors. Data are from a sample of 2447 respondents aged 18-65 years of the Netherlands Study of Depression and Anxiety (NESDA). Baseline depressive disorders and anxiety disorders were determined with the Composite International Diagnostic Interview (CIDI). Weight at baseline and after 2 years was measured and analyzed as continuous change score (mean change in weight 1kg) and in categories of significant weight loss (<1S.D. weight change equaling <4kg), weight maintenance and weight gain (>1S.D., >6kg). After full adjustment for covariates baseline comorbid anxiety and depressive disorder and baseline Major Depressive Disorder (MDD) were associated with significant 2-year weight gain. Both current and remitted MDD at baseline and a baseline dysthymia, but none of the anxiety disorders, were associated with significant weight loss. This longitudinal study confirms a U-curved link between depression and weight change over 2 years. Furthermore, a dose-response effect of depression severity on 2-year weight gain was found.

    2008-11-01

    This study aims to examine the usefulness of spontaneous upper limb movements (ULM) as an early marker for predicting neurodevelopmental outcome in infants with intrauterine-growth retardation (IUGR). The assessment of general movements (GMs) during the first 20 weeks is an accepted method for early detection of brain dysfunction. During this period, spontaneous upper limb movements were examined in 32 infants with IUGR and 32 appropriate-for-gestational-age-matched controls. ULM (arms, forearms and hands) were scored as optimal or suboptimal by sequential videotape recordings in the writhing (term-2 weeks: score 0-5); early fidgety (9-11 weeks: score 0-6); and late fidgety (14-16 weeks: score 0-6) periods, and correlated with neurodevelopmental score at 2 years of age. The mean ULM score was lower in the IUGR infants than the controls (p<0.05) and in the IUGR group was lower in the infants with abnormal outcome (p<0.05). Significant correlations were found between ULM and 2-year neurodevelopmental scores in the IUGR group. The ULM during late-fidgety period was most predictive for 2-year neurodevelopmental score. No difference was found in the mean ULM score between the pre-term and term IUGR infants. We conclude that ULM score can serve as an early predictor for neurodevelopmental outcome at 2 years of age in infants with IUGR.

  13. Coordination of Lip Muscle Activity by 2-Year-Old Children During Speech and Nonspeech Tasks

    2014-01-01

    This investigation was designed to quantify the coordinative organization of lip muscle activity of 2-year-old children during speech and nonspeech behaviors. Electromyographic (EMG) recordings of right upper and lower lip activity of seven 2-year-old children were obtained during productions of chewing, syllable repetition, lip protrusion, and speech (repeated two-word utterances) tasks. Task comparisons revealed that the coordinative organization of upper and lower lip activity is task specific; different coordinative strategies are employed for different tasks. Lip protrusion and syllable repetition tasks yielded strong coupling of upper and lower lip activity. Lip rounding (sentences containing the lip-rounding vowel /u/) and “nonlabial” speech tasks (sentences free of bilabials and lip-rounding vowels) resulted in low coupling of upper and lower lip activity. Moderate levels of coupling of upper and lower lip activity were evident for chewing and bilabial speech tasks (sentences loaded with bilabial plosion). This finding, that the coordinative elements of the perioral system of 2-year-olds are task specific, extends the results of previous studies of adults and children, where task-specific coordinative strategies were employed by the mandibular and perioral systems (Moore, 1993; Moore & Ruark, 1996; Moore, Smith, & Ringel, 1988; Wohlert & Goffman, 1994). The task-dependent coordination of the perioral system of 2-year-olds supports the notion that developing speech and earlier developing oromotor behaviors (i.e., sucking, chewing) are mediated by different control mechanisms.

    Human cortical folding is believed to correlate with cognitive functions. This likely correlation may have something to do with why abnormalities of cortical folding have been found in many neurodevelopmental disorders. However, little is known about how cortical gyrification, the cortical folding process, develops in the first 2 years of life, a period of dynamic and regionally heterogeneous cortex growth. In this article, we show how we developed a novel infant-specific method for mapping longitudinal development of local cortical gyrification in infants. By using this method, via 219 longitudinal 3T magnetic resonance imaging scans from 73 healthy infants, we systemically and quantitatively characterized for the first time the longitudinal cortical global gyrification index (GI) and local GI (LGI) development in the first 2 years of life. We found that the cortical GI had age-related and marked development, with 16.1% increase in the first year and 6.6% increase in the second year. We also found marked and regionally heterogeneous cortical LGI development in the first 2 years of life, with the high-growth regions located in the association cortex, whereas the low-growth regions located in sensorimotor, auditory, and visual cortices. Meanwhile, we also showed that LGI growth in most cortical regions was positively correlated with the brain volume growth, which is particularly significant in the prefrontal cortex in the first year. In addition, we observed gender differences in both cortical GIs and LGIs in the first 2 years, with the males having larger GIs than females at 2 years of age. This study provides valuable information on normal cortical folding development in infancy and early childhood.

    Hip arthroscopy in patients with osteoarthritis has been shown to have suboptimal outcomes. Elevated cytokine concentrations in hip synovial fluid have previously been shown to be associated with cartilage pathology. The purpose of this study was to determine whether a relationship exists between hip synovial fluid cytokine concentration and clinical outcomes at a minimum of 2 years following hip arthroscopy. Seventeen patients without radiographic evidence of osteoarthritis had synovial fluid aspirated at time of portal establishment during hip arthroscopy. Analytes included fibronectin–aggrecan complex as well as a multiplex cytokine array. Patients completed the modified Harris Hip Score, Western Ontario and McMaster Universities Arthritis Index and the International Hip Outcomes Tool pre-operatively and at a minimum of 2 years following surgery. Pre and post-operative scores were compared with a paired t-test, and the association between cytokine values and clinical outcome scores was performed with Pearson’s correlation coefficient with an alpha value of 0.05 set as significant. Sixteen of seventeen patients completed 2-year follow-up questionnaires (94%). There was a significant increase in pre-operative to post-operative score for each clinical outcome measure. No statistically significant correlation was seen between any of the intra-operative cytokine values and either the 2-year follow-up scores or the change from pre-operative to final follow-up outcome values. No statistically significant associations were seen between hip synovial fluid cytokine concentrations and 2-year follow-up clinical outcome assessment scores for those undergoing hip arthroscopy.

    Preterm infants are at greater risk of bronchopulmonary dysplasia, which is associated with neurodevelopmental impairment. These infants are also more likely to develop severe bronchiolitis, which can contribute to neurodevelopmental impairment. The aim of this study was to determine whether severe bronchiolitis in very preterm infants (born before 33 weeks of gestation) was associated with an increased risk of neurodevelopmental impairment at 2 years of age. We analyzed a population-based cohort of infants (the Loire Infant Follow-up Team cohort) born between 1 January 2003 and 31 December 2009. Severe bronchiolitis was defined as hospitalization due to bronchiolitis during the first year of life. Neurodevelopmental outcome was assessed at 2 years of corrected age. A total of 2,405 infants were included in this analysis and categorized based on neonatal respiratory status: 1,308 (54.4 %) received no respiratory assistance, 864(35.9 %) received oxygen for <28 days, and 167 (6.9 %) had mild and 66 (2.7) moderate or severe bronchopulmonary dysplasia. At 2 years, 502 children displayed non-optimal neurodevelopmental outcome (20.9 %). Moderate or severe bronchopulmonary dysplasia was significantly associated with non-optimal neurodevelopmental outcome at 2 years (adjusted odds ratios (OR) = 2.3 [95 % confidence interval (CI): 1.3-3.9], p = 0.003). In the first year, 318 infants acquired severe bronchiolitis (13.2 %), which was not associated with non-optimal neurodevelopmental outcome (adjusted OR = 1.0 [95 % CI: 0.8-1.4]; p = 0.88). In conclusion, respiratory status in the neonatal period was significantly associated with non-optimal neurodevelopmental outcome at 2 years, while severe bronchiolitis was not.

    This study aims to investigate salivary flow and biochemical constituents of menopausal-age women with the hypothesis that women using hormone therapy (HT) might present better saliva values than non-users. Two hundred HT users and 200 non-users were selected at random from a cohort study of 3,173 peri- and postmenopausal women and invited to a 2-year clinical follow-up study. Clinical examination with saliva sampling was made at baseline and 2 years later. Salivary total protein, albumin, and immunoglobulin (Ig) concentrations were analyzed. Final material included 106 consistent HT users and 55 non-users. Backward logistic regression analysis was made to determine the risk factors for higher or lower than medium salivary protein values. No difference was seen in salivary flow rate, total protein, and IgA values between baseline and follow-up measurements or between the groups. Albumin, IgG, and IgM concentrations were significantly lower in the 2-year samples of the HT group when compared with baseline. IgA and IgM values were higher in the non-HT 2-year samples when compared with the corresponding HT samples. The only significant explanatory factor for higher than median salivary albumin concentration was the number of teeth both at baseline and 2 years later. HT possibly improved epithelial integrity since the concentrations of serum components albumin, IgG, and IgM decreased during the follow-up. HT as such does not seem to affect saliva, although it may modify it. The clinical relevance of these results needs to be assessed in future studies.

    The aim of the present study was to assess the role of cardiovascular risk factors in the occurrence of cardiovascular events among 100 consecutive renal transplant recipients during the first 2 years after transplantation. The following parameters were analyzed: (1) demographic data (gender, age, dialysis duration, preexistent diabetes, and pretransplantation events) as well as (2) basal 1-year, and 2-year posttransplantation data for events, body mass index, arterial hypertension, number of drugs for hypertension control, use of ACE or ARA II inhibitors, treatment with lipid- lowering drugs, de novo diabetes, anemia, immunosuppression with cyclosporine versus tacrolimus, and homocysteine, folic acid, serum creatinine, uric acid, PTH-i, and cholesterol total, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, and triglyceride levels. At the end of the second posttransplantation year, 14 patients versus 86 who did not experience a new cardiovascular event. Patients in the event group had more events pretransplantation and during the first posttransplantation year than those in the non event group (57.1% vs 17.4%; P = .003 and 78.6% vs 2.3%; P = .000, respectively). Furthermore, the former cohort of patients were older, had greater ventricular hypertrophy and had higher triglyceride and serum creatinine concentrations during the 2 years after transplantation. A multiple logistic regression analysis confirmed the relationship between events within 1 year of transplantation and serum creatinine level at the end of 2 years as well as the development of cardiovascular disease within 2 years. In conclusion, our data suggest the need for aggressive intervention during the first year to prevent the development of new cardiovascular events. Renoprotective strategies may also contribute to reduce the cardiovascular risk of renal transplant recipients.

    Purpose: To retrospectively determine the incidence and patterns (in-field, marginal, or out-of-field) of locoregional gastric cancer recurrence in patients who received preoperative chemoradiotherapy and to determine the outcome in these patients. Methods and Materials: Between 1994 and 2004, 149 patients with gastric carcinoma were treated according to institutional protocols with preoperative chemoradiotherapy. Ultimately, 105 patients had an R0 resection. Of these 105 patients, 65 received preoperative chemotherapy followed by chemoradiotherapy and 40 received preoperative chemoradiotherapy. Most (96%) of these patients received 5-fluorouracil-based chemotherapy during radiotherapy, and the median radiation dose was 45 Gy. We retrospectively identified and classified the patterns of locoregional recurrence. Results: The 3-year actuarial incidence of locoregional recurrence was 13%, with locoregional disease recurring as any part of the failure pattern in 14 patients. Most (64%) of the evaluable locoregional recurrences were in-field. Of the 4 patients with a marginal recurrence, 2 had had inadequate coverage of the regional nodal volumes on their oblique fields. The pathologic complete response rate was 23%. A pathologic complete response was the only statistically significant predictor of locoregional control. Conclusion: Patients with gastric cancer who received preoperative chemoradiotherapy had low rates of locoregional recurrence. This strategy merits prospective multi-institutional and randomized evaluation.

    With the increased incidence of whiplash injury following the introduction of compulsory car seat belts, a large number of reports have dealt with the aftermath of this condition. Previous studies, however, focused on somatic symptoms on the one hand or considered only psychological or neuropsychological variables on the other hand, often in loosely defined or selected groups of patients. No study so far has analyzed the long-term outcome in a nonselected group of patients using a clear injury definition considering patient history; somatic, radiologic, and neuropsychological findings; and features of the injury mechanisms assessed soon after trauma and during follow-up. the present investigation was designed to assess these combined factors. According to a strict definition of whiplash injury, we assessed a consecutive nonselected sample of 117 patients with recent injury who had similar sociocultural and educational backgrounds. The patients had been in automobile crashes and were all equally covered by accident insurance according to the country-wide scheme. Initial examination was performed 7.2 +/- 4.2 days after trauma, and follow-up examinations 3, 6, 12, and 24 months later. At baseline, features of injury mechanism, subjective complaints, and different aspects of patient history were documented and cervical spine X rays performed. At all examinations patients underwent neurologic examination and cognitive and psychosocial factor assessment. At 2 years, patients were divided into symptomatic and asymptomatic groups and then compared with regard to the initial findings. In addition, symptomatic patients who were disabled at the 2-year follow-up examination and symptomatic patients not disabled (that is, they were able to work at the pretraumatic level) were compared regarding initial and 2-year findings. At 2 years, 18% of patients still had injury-related symptoms. With regard to baseline findings the following significant differences were found: Symptomatic

  1. Altitude Modulates Concussion Incidence

    Background: Recent research indicates that the volume and/or pressure of intracranial fluid, a physiology affected by one’s altitude (ie, elevation above sea level), may be associated with the likelihood and/or severity of a concussion. The objective was to employ an epidemiological field investigation to evaluate the relationship between altitude and concussion rate in high school sports. Hypothesis: Because of the physiologies that occur during acclimatization, including a decline in intracranial compliance (a “tighter fit”), increased altitude may be related to a reduction in concussion rates in high school athletes. Study Design: Cohort study; Level of evidence, 3. Methods: Data on concussions and athlete exposures (AEs) between 2005-2006 and 2011-2012 were obtained from a large national sample of high schools (National High School Sports-Related Injury Surveillance System [High School RIO]) and were used to calculate total, competition, and practice concussion rates for aggregated sports and for football only. Results: Altitude of participating schools ranged from 7 to 6903 ft (median, 600 ft), and a total of 5936 concussions occurred in 20,618,915 exposures (2.88 per 10,000 AEs). When concussion rates were dichotomized by altitude using the median, elevated altitude was associated with a reduction in concussion rates overall (rate ratio [RR], 1.31; P < .001), in competition (RR, 1.31; P < .001), and in practice (RR, 1.29; P < .001). Specifically, high school sports played at higher altitude demonstrated a 31% reduction (95% confidence interval [CI], 25%-38%) in the incidence of total reported concussions. Likewise, concussion rates at increased altitude were reduced 30% for overall exposures, 27% for competition exposures, and 28% for practice exposures in football players (P < .001). Conclusion: The results of this epidemiological investigation indicate increased physiological responses to altitude may be associated with a reduction in sports

    Objective Evaluate the longterm effects of a brief group cognitive-behavioral (CB) adolescent depression indicated prevention program through 2-year follow-up, relative to CB bibliotherapy and brochure control, when high school personnel recruited students and delivered the program. Method 378 adolescents (M age = 15.5, SD = 1.2; 68% female, 72% White) with elevated self-assessed depressive symptoms who were randomized to CB group, CB bibliotherapy, or educational brochure control were assessed at pre, post, 6-, 12-, 18-, and 24-month follow-up. Results By 2 years post-intervention, CB group participants showed significantly lower major depressive disorder (MDD) onset versus CB bibliotherapy (10% vs. 25%, respectively; HR = 2.48, p = .006), but the incidence difference relative to brochure controls (17%) was nonsignificant; MDD incidence for bibliotherapy and brochure controls did not differ. Although CB group participants showed lower depressive symptoms at post versus brochure controls, there were no effects for this outcome or for social adjustment or substance use over 2-year follow-up. Moderator analyses suggested that participants with higher baseline depressive symptoms showed greater longterm symptom reductions in the CB group intervention versus bibliotherapy. Conclusions The evidence that a brief CB group intervention delivered by real-world providers significantly reduced MDD onset versus CB bibliotherapy is potentially encouraging. However, the lack of MDD prevention effects relative to brochure control and lack of longterm symptom effects (though consistent with results from other depression prevention trials), suggest that the delivery of CB group should be refined to strengthen its effectiveness.

    This is the first case report describing a complete response to bicalutamide withdrawal that lasted for almost 2 years in a patient with metastatic prostate cancer. An 80-year-old man who had prostate-specific antigen (PSA) level elevation (168.1 ng/mL) visited our hospital in February 2010. Bone scintigraphy showed pelvic metastases. We started hormonal therapy with leuprorelin and bicalutamide. The PSA concentration decreased to <0.1 ng/mL but started increasing again and reached 1.64 ng/mL in October 2012, at which time bicalutamide administration was discontinued. The PSA concentration decreased again and has remained below the limit of sensitivity for almost 2 years.

    We longitudinally investigated parental language context and infants' language experiences in relation to Dominican American and Mexican American infants' vocabularies. Mothers provided information on parental language context, comprising measures of parents' language background (i.e., childhood language) and current language use during interviews at infants' birth. Infants' language experiences were measured at ages 14 months and 2 years through mothers' reports of mothers' and fathers' engagement in English and Spanish literacy activities with infants and mothers' English and Spanish utterances during videotaped mother-infant interactions. Infants' vocabulary development at 14 months and 2 years was examined using standardized vocabulary checklists in English and Spanish. Both parental language context and infants' language experiences predicted infants' vocabularies in each language at both ages. Furthermore, language experiences mediated associations between parental language context and infants' vocabularies. However, the specific mediation mechanisms varied by language.

    Cystic structures within the pericardial cavity are rare. They are divided into epicardial and pericardial variants. Pericardial and epicardial cysts rarely cause symptoms. This report describes a case of epicardial cyst with acute cardiac tamponade in a 2-year-old boy with no previous cardiac history who was transferred to our hospital because of hemodynamic instability. Emergency drainage of the pericardial effusion and complete excision of the cyst were performed through a median full sternotomy.

    Uric acid (UA) is reduced in multiple sclerosis (MS), and possibly relates to MS outcomes, with lower UA levels in subjects experiencing a relapse or presenting higher disability scores. The present retrospective longitudinal study evaluated UA variations in MS, in relation to clinical relapses, disability progression, and cognitive functions. We included 141 subjects with relapsing-remitting MS (RRMS) and performed expanded disability status scale (EDSS), symbol digit modalities test (SDMT) and UA evaluation at baseline visit and after 2-year follow-up. Paired t test showed significantly lower UA levels after 2-year follow-up than at baseline (3.987 ± 1.135 and 4.167 ± 1.207 mg/dL, respectively) (p = 0.001). The difference in UA levels between 2-year follow-up and baseline related to EDSS sustained progression (p < 0.001; OR = 0.099), and presented a trend for clinical relapses at logistic regression (p = 0.211; OR = 0.711) and for the time to relapse at Cox regression (p = 0.236; HR = 0.792). Analysis of variance showed reduced baseline UA levels in subjects with impaired SDMT at baseline (p = 0.045; adjusted R(2) = 0.473) and after 2-year follow-up (p = 0.034; adjusted R(2) = 0.470). This is the first study showing a progressive reduction of UA levels during the course of RRMS, suggesting a progressive decrease of antioxidant reserves, in relation to relapse risk, disability progression and cognitive function.

    A common complaint after inflatable penile prosthesis surgery is reduced penile length. We previously reported how using the Coloplast Titan inflatable penile prosthesis with aggressive new length measurement technique (NLMT) coupled with postoperative IPP rehabilitation of the implant for 1-year helped to improve patient satisfaction and erectile penile measurements. This is a 2 years follow-up of a prospective, three-center, study of 40 patients who underwent Titan prosthesis placement, with new length measurement technique for erectile dysfunction. Patient instructions were to inflate daily for 6 months and then inflate maximally for 1–2 h daily for 6–24 months. Fifteen penile measurements were taken before and immediately after surgery and at follow-up visits. Measurement changes were improved at 24 months as compared to immediately postoperative and at 12 months. 67.8% of subjects were satisfied with their length at 2 years, and 77% had perceived penile length that was longer (30.8%) or the same (46.2%) as prior to the surgery. 64.3% and 17.9% of subjects had increased and unchanged satisfaction, respectively, with penile length as compared to prior to penile implant surgery. All but one subject (96.5%) was satisfied with the overall function of his implant. This study suggests using the Coloplast Titan with aggressive cylinder sizing, and a postoperative penile rehabilitation inflation protocol can optimize patient satisfaction and erectile penile measurements at 2 years postimplant.

    The aim of this study was to determine whether a postnatal ultrasound (US) can detect infants with antenatal renal pelvis dilatation (ARPD) who run a minimal risk of renal damage 2 years after birth. The study cohort consisted of 14,000 pregnant women who consecutively underwent routine US examinations during the second trimester. Subsequent examinations were performed on the basis of obstetrical indications. In total, 106 foetuses were diagnosed with ARPD > or =5 mm. Two postnatal US were performed on the newborns: on postpartum days 5-7 and during the third week of life. The findings were considered to be normal when the renal pelvis diameter (RPD) was < or = 7 mm and when there was no calyceal or ureteric dilatation or signs of renal dysplasia or other anomalies. Voiding cystourethrography (VCUG) was done at 6-8 weeks after birth. When the children reached 2 years of age, renal status was evaluated with DMSA scintigraphy or, if not possible, US. In 53 of the 103 children available for evaluation, the postnatal US findings were normal; 49 of the 53 children were also given a DMSA, and the results were normal in all cases. An US scan (all normal) only was performed in three children because the families refused a DMSA. One family refused any form of examination at the 2-year follow-up. Based on our results, we conclude that postnatal US can detect infants who do not require follow-up assessments of renal development.

    Children born very preterm are at greater risk of ophthalmic morbidities, including strabismus, than children born at term. We evaluated perinatal factors associated with strabismus at age 2 years in a large population of infants delivered before 28 weeks’ gestation. A total of 996 infants in the multicenter ELGAN (Extremely Low Gestational Age Newborn) study who had a retinal exam in infancy and a developmental assessment at 2 years corrected age are included. Their mothers were interviewed about the pregnancy, and both mother and newborn charts were reviewed. Certified examiners administered the Bayley Scales of Infant Development-II and performed an examination of ocular alignment. Time-oriented logistic regression risk models were created to evaluate the associations of characteristics and exposures with the development of strabismus. Overall, 14% (n = 141) of the children had strabismus at 2 years, and 80% of strabismic children had esotropia. Characteristics associated with strabismus were birth before 26 weeks’ gestation, severe fetal growth restriction, and maternal history of aspirin ingestion. Associated postnatal factors included a SNAP-II (Score for Neonatal Acute Physiology) illness severity value ≥30, brain ventriculomegaly, type I retinopathy of prematurity, and ventilator-dependent severe bronchopulmonary dysplasia. Strabismus in very preterm populations is associated with a number of antenatal and postnatal antecedents as well as clinical and imaging correlates indicative of brain damage in these children. Routine ophthalmologic assessments in the early years can allow appropriate and timely interventions. PMID:26350726

    This work describes the potential usefulness of bioflavonoids for countering the deleterious effects of aging on male sexuality in 2-year-old rats. A flavone chrysin from Passiflora caerulea Linn. and a benzoflavone moiety (BZF) recently isolated from Passiflora incarnata Linn. were administered to 2-year-old male rats for a period of 30 days. After cessation of these treatments, there was a significant improvement in overall sexual functions in the rats given bioflavonoids, compared with control rats. The rats receiving chrysin (1 mg/kg) and BZF (10 mg/kg) exhibited increased libido when they were allowed to interact with nonestrous female rats. Additionally, both treated groups had increased sperm count, greater fertilization potential, and greater litter size when they were allowed to interact with proven proestrous female rats of a similar strain. BZF was more potent than chrysin as an antiaromatase agent and exhibited better effects on the sexual system of the 2-year-old male rats. Plant flavonoids have great potential for clinical and therapeutic applications against the physiological and biochemical effects of aging.

    Accelerated atherosclerosis is a major cause of mortality in SLE. Mycophenolate mofetil (MMF) has been shown to suppress growth factor-induced proliferation of vascular smooth muscle and endothelial cells in animal models. We hypothesized that MMF might modify the inflammatory component of atherosclerosis in SLE. We examined the effect of MMF on atherosclerosis as measured by changes in carotid intima-media thickness (IMT) or coronary artery calcium (CAC) over 2 years. CAC and carotid IMT were measured at baseline and 2 years later in a cohort of 187 patients with SLE. The cohort was 91% women, 59% Caucasian, and 35% African-American, with a mean age of 45 ± 11 years. Of these, 12.5% (n = 25) received MMF during follow-up. The daily dose ranged from 500 to 3,000 mg/day, and duration ranged from 84 days to the entire 2 years. We divided MMF users into three groups: low exposure (<1,500 mg average daily dose), high exposure (≥1,500 average daily dose), and any exposure of MMF (<1,500 or ≥1,500 average daily dose) for 2 years. The mean CAC increased in all four groups: no MMF: 1.17-1.28, low MMF: 1.02-1.13, high MMF: 1.44-1.61, and any MMF: 1.21-1.34 log-Agatston units. Compared to no MMF, there was no statistically different change between the three groups (p = 0.99, 0.87, and 0.91). Similarly, mean carotid IMT increased in all four groups: no MMF: 0.58-0.66, low MMF: 0.55-0.60, high MMF: 0.56-0.71, and any MMF: 0.56-0.66. We then adjusted for statin use, lupus nephritis, body mass index, systolic blood pressure, cholesterol, and age during the 2-year follow-up. The association between MMF exposure and change in CAC or carotid IMT was not statistically significant (p = 0.63 for CAC, and p = 0.085 for carotid IMT). There was no evidence that MMF slowed or decreased the progression of atherosclerosis as measured by carotid IMT or CAC. Because the number of patients taking MMF was only twenty-five, larger studies for longer time periods are needed to explore any

    Background The Kineflex lumbar disc is a mechanical, unconstrained, re-centering disc prosthesis developed in South Africa. The first implantation took place in October 2002. We present a single-center, prospective, longitudinal study of the first 100 patients treated with the Kineflex lumbar disc. Our objective was to evaluate the insertion technique, clinical outcomes, and patient satisfaction at 2 years postimplantation in 100 consecutive patients with 132 (68 single- and 32 2-level) Kineflex lumbar disc replacements. Methods We determined the exact central placement of all disc implants in the coronal and midsagittal planes. We measured clinical outcome with the Oswestry disability index (ODI), our own questionnaire, and the time needed to return to work. All patients received radiological and clinical follow-up assessments for 2 years after the index procedure. Results Forty-three patients were female. The mean age of the patients at operation was 44.9 years (range, 23–63 years). Postoperative hospitalization averaged 2.8 days (range, 2 to 8 days). All patients who were employed before surgery returned to work 31 ± 16.8 days after the operation. Fifty-six percent of operated disc levels had intervertebral disc heights of less than 5 mm. A 2-year clinical outcome was available for 98 of the 100 patients (58 excellent, 30 good, 7 fair, 3 poor). The ODI score improved from 47.8 ± 16.0 preoperatively to 14.2 ± 14.0 (P < .01) at 2 years. At 2 years, 95% of disc implants were radiologically in the ideal position. The insertion technique, with a released prosthetic mechanism for final placement, allowed ideal placement in the sagittal plane in 98% of discs. The radiographic placement accuracy achieved was equal in patients with preoperative intervertebral disc height below and above 5 mm. Conclusions Good short-term clinical results were achieved with the Kineflex disc in a heterogeneous patient group with a high number of patients with advanced disc

    The present study is an examination of sex offender treatment outcome in a large national cohort of Canadian Federally incarcerated sex offenders followed up an average of 11.7 years postrelease. A brief actuarial risk scale (BARS), which predicted sexual and violent recidivism, was created for the purposes of the present study to control for risk-related differences between treated and untreated offenders. In total, 732 offenders were identified as having completed (n = 625) or not attended (n = 107) a sex offender treatment program and for whom sufficient information was available to complete the scale. Controlling for risk and individual differences in follow-up time using Cox regression survival analyses and an 8-year fixed follow-up period, treated sex offenders demonstrated significantly lower rates of violent, but not sexual, recidivism. When the treated and untreated groups were stratified by risk level, significant differences were observed only among moderate or high risk offenders. Some significant group differences also emerged on indicators of recidivism severity, with treated offenders demonstrating slower times to sexual reoffense and lower scores on a quantified metric of sexual and violent recidivism severity after controlling for risk. Differences in recidivism base rates between treated and untreated offenders were also larger in magnitude for younger offenders (i.e., under age 50 at release), than for older offenders; however, interactions between age and treatment were not found. The findings are consistent with the risk principle and have possible implications regarding the dynamic nature of sexual violence risk.

    A performance capability assessment is presently conducted for short versus long grazing incidence telescope designs, in view of the observation that the field curvature and astigmatism that are the primary residual aberrations of a Wolter-type incidence telescope can be substantially reduced through mirror length reduction. A major advantage of the short element telescope is that, if sufficiently short, both the paraboloid and hyperboloid surfaces may be fabricated as a single piece; this significantly facilitates the task of alignment.

    Study Objectives: Following the 2009 pandemic, reports of an association between an AS03 adjuvanted H1N1 pandemic influenza vaccine and narcolepsy were published. Besides determining background incidence rates for narcolepsy in Germany this study aimed at investigating whether there was a change in incidence rates of narcolepsy between the pre-pandemic, pandemic, and the post-pandemic period on the population level. Design: Retrospective epidemiological study on the incidence of narcolepsy with additional capture-recapture analysis. Setting: German sleep centers. Patients or Participants: Eligible were patients with an initial diagnosis of narcolepsy (ICD10 Code G47.4) within the period from January 1, 2007 to December 31, 2011. Interventions: None; observational study. Measurements and Results: A total of 342 sleep centers were invited to participate in the study. Adequate and suitable data were provided by 233 sleep centers (68.1%). A total of 1,198 patients with an initial diagnosis of narcolepsy within the observed period were included, of whom 106 (8.8%) were children and adolescents under the age of 18 years and 1,092 (91.2%) were adults. In children and adolescents, the age-standardized adjusted incidence rate significantly increased from 0.14/100,000 person-years in the pre-pandemic period to 0.50/100,000 person-years in the post-pandemic period (incidence density ratio, IDR 3.57; 95% CI 1.94–7.00). In adults, no significant change was detectable. This increase started in spring 2009. Conclusions: For the years 2007–2011, valid estimates for the incidence of narcolepsy in Germany were provided. In individuals under 18, the incidence rates continuously increased from spring 2009. Citation: Oberle D, Drechsel-Bäuerle U, Schmidtmann I, Mayer G, Keller-Stanislawski B.

    The Analysis Function of the US-CERT Control Systems Security Center (CSSC) at the Idaho National Laboratory (INL) has prepared this report to document cyber security incidents for use by the CSSC. The description and analysis of incidents reported herein support three CSSC tasks: establishing a business case; increasing security awareness and private and corporate participation related to enhanced cyber security of control systems; and providing informational material to support model development and prioritize activities for CSSC. The stated mission of CSSC is to reduce vulnerability of critical infrastructure to cyber attack on control systems. As stated in the Incident Management Tool Requirements (August 2005) ''Vulnerability reduction is promoted by risk analysis that tracks actual risk, emphasizes high risk, determines risk reduction as a function of countermeasures, tracks increase of risk due to external influence, and measures success of the vulnerability reduction program''. Process control and Supervisory Control and Data Acquisition (SCADA) systems, with their reliance on proprietary networks and hardware, have long been considered immune to the network attacks that have wreaked so much havoc on corporate information systems. New research indicates this confidence is misplaced--the move to open standards such as Ethernet, Transmission Control Protocol/Internet Protocol, and Web technologies is allowing hackers to take advantage of the control industry's unawareness. Much of the available information about cyber incidents represents a characterization as opposed to an analysis of events. The lack of good analyses reflects an overall weakness in reporting requirements as well as the fact that to date there have been very few serious cyber attacks on control systems. Most companies prefer not to share cyber attack incident data because of potential financial repercussions. Uniform reporting requirements will do much to make this information available to

    Anterior cervical decompression for two or more cervical spondylotic levels can be performed using either multiple anterior cervical discectomies and fusion or anterior cervical corpectomy and fusion (ACCF). A variety of options for ACCF implants exist but to our knowledge, there is no clinical data for the use of tantalum trabecular metal implants (TTMI) for ACCF. A retrospective review was performed of prospectively collected data for ten patients undergoing ACCF with TTMI between 2011 and 2012. Radiological outcome was assessed by measuring the change in cervical (C) lordosis (fusion Cobb and C2-C7 Cobb), graft subsidence (anterior/posterior, determined by the subsidence of anterior/posterior body height of fused segments; cranial/caudal, determined by the cranial/caudal plate-to-disc distances) and rate of fusion using lateral cervical X-rays of patients at 0, 6, 12 and 24months post-operatively. The Neck Disability Index (NDI) assessed clinical outcome pre-operatively and at 6, 12 and 24months post-operatively. Cervical lordosis (Cobb angle of fused segment) was 5.2° (± 4.2°) at 0months and 6.0° (± 5.7°) at 24months post-operatively. Graft subsidence was observed to occur at 6months post-operatively and continued throughout follow-up. Anterior, posterior and caudal subsidence occurred more in the first 12months post-operatively than in the following 12months (p<0.05). Average pre-operative NDI was 45%. Average NDIs were 18%, 13% and 10% at 6, 12 and 24months post-operatively, respectively. ACCF patients treated with TTMI demonstrated stable cervical lordosis over 2years of follow-up and 100% fusion rates after 2years. Measures of subsidence appeared to decrease with time. Patients experienced improved clinical outcomes over the 2-year period.

    Background On March 11, 2011, a massive undersea earthquake and tsunami struck East Japan. Few studies have investigated the impact of exposure to a natural disaster on preschool children. We investigated the association of trauma experiences during the Great East Japan Earthquake on clinically significant behavior problems among preschool children 2 years after the earthquake. Method Participants were children who were exposed to the 2011 disaster at preschool age (affected area, n = 178; unaffected area, n = 82). Data were collected from September 2012 to June 2013 (around 2 years after the earthquake), thus participants were aged 5 to 8 years when assessed. Severe trauma exposures related to the earthquake (e.g., loss of family members) were assessed by interview, and trauma events in the physical environment related to the earthquake (e.g. housing damage), and other trauma exposure before the earthquake, were assessed by questionnaire. Behavior problems were assessed by caregivers using the Child Behavior Checklist (CBCL), which encompasses internalizing, externalizing, and total problems. Children who exceeded clinical cut-off of the CBCL were defined as having clinically significant behavior problems. Results Rates of internalizing, externalizing, and total problems in the affected area were 27.7%, 21.2%, and 25.9%, respectively. The rate ratio suggests that children who lost distant relatives or friends were 2.36 times more likely to have internalizing behavior problems (47.6% vs. 20.2%, 95% CI: 1.10–5.07). Other trauma experiences before the earthquake also showed significant positive association with internalizing, externalizing, and total behavior problems, which were not observed in the unaffected area. Conclusions One in four children still had behavior problems even 2 years after the Great East Japan Earthquake. Children who had other trauma experiences before the earthquake were more likely to have behavior problems. These data will be

    Numerous brain imaging studies indicate that the corpus callosum is smaller in older children and adults with autism spectrum disorder. However, there are no published studies examining the morphological development of this connective pathway in infants at-risk for the disorder. Magnetic resonance imaging data were collected from 270 infants at high familial risk for autism spectrum disorder and 108 low-risk controls at 6, 12 and 24 months of age, with 83% of infants contributing two or more data points. Fifty-seven children met criteria for ASD based on clinical-best estimate diagnosis at age 2 years. Corpora callosa were measured for area, length and thickness by automated segmentation. We found significantly increased corpus callosum area and thickness in children with autism spectrum disorder starting at 6 months of age. These differences were particularly robust in the anterior corpus callosum at the 6 and 12 month time points. Regression analysis indicated that radial diffusivity in this region, measured by diffusion tensor imaging, inversely predicted thickness. Measures of area and thickness in the first year of life were correlated with repetitive behaviours at age 2 years. In contrast to work from older children and adults, our findings suggest that the corpus callosum may be larger in infants who go on to develop autism spectrum disorder. This result was apparent with or without adjustment for total brain volume. Although we did not see a significant interaction between group and age, cross-sectional data indicated that area and thickness differences diminish by age 2 years. Regression data incorporating diffusion tensor imaging suggest that microstructural properties of callosal white matter, which includes myelination and axon composition, may explain group differences in morphology.

    Preterm infants in a neonatal intensive care unit (NICU) are exposed to multidrug-resistant bacteria previously adapted to the hospital environment. The aim of the present study was to characterize the bacterial antibiotic-resistant high-risk lineages colonizing preterm infants during their NICU stay and their persistence in faeces after 2 years. A total of 26 preterm neonates were recruited between October 2009 and June 2010 and provided 144 faecal samples. Milk samples (86 mother's milk, 35 human donor milk and 15 formula milk) were collected at the same time as faecal samples. An additional faecal sample was recovered in 16 infants at the age of 2 years. Samples were plated onto different selective media, and one colony per morphology was selected. Isolates were identified by 16S rDNA nucleotide sequence and MALDI-TOF. Antibiotic susceptibility (agar dilution), genetic diversity (RAPD, PFGE and MLST) and virulence factors (only in enterococcal and staphylococcal isolates) were determined by PCR. A high proportion of antibiotic-resistant high-risk clones was detected in both faecal and milk samples during the NICU admittance. Almost all infants were colonized by Enterococcus faecalis ST64 and Enterococcus faecium ST18 clones, while a wider genetic diversity was observed for the Gram-negative isolates. Multidrug-resistant high-risk clones were not recovered from the faecal samples of the 2-year-olds. In conclusion, the gut of preterm infants admitted to the NICU might be initially colonized by antibiotic-resistant and virulent high-risk lineages, which are later replaced by antibiotic-susceptible community ones.

    Biosphere 2's finite natural resources: atmosphere, plants, water, and soil, and its unique increased rate of nutrient cycling, mandated a design for the agriculture that emphasized sustainability and high productivity. The results of the initial 2-year test of the agriculture system showed that it could provide a diet that was both nutritionally adequate and pleasing to the palate of the eight-member crew from September 1991 to September 1993. The agriculture design was developed from 1985 to 1991 at the Space Biospheres research greenhouses with consulting from the Institute of Ecotechnics (London) from its experiments in New Mexico, Australia, and France and the Environmental Research Laboratory (University of Arizona). During the 2-year mission this research was continued with the close collaboration of outside scientific consultants, particularly in the area of soil management and integrated pest management. The 2000-m2 cropping area provided approximately 81% of the overall nutritional needs of the crew. Initial results showed light to be the main limiting factor and the additional electric light was added after the first 2-year mission to increase the productivity for future experiments. The diet was primarily vegetarian supplemented with daily amounts of milk, and weekly meals of meat and eggs from the system's domestic goats, pigs, and chickens. Nontoxic methods of pest and disease control were used. The main pest problems were broad mite and root knot nematode. Inedible plant material, domestic animal wastes, and human waste water were successfully processed for nutrient return to the soil. Eighty-six varieties of crops were grown in Biosphere 2. Major staple crops included rice, sweet potato, beets, banana, and papaya. The African pygmy goats were the most productive of the domestic animals producing on average 1.14 kg of milk per day. The diet averaged 2200 calories, 73 g of protein, and 32 g of fat per person per day over the 2 years. The crew had a 10

    Meningiomas are common lesions in adults but unusual in infancy and meningiomas located in the posterior cranial fossa are even more rare. Metaplastic changes of meningothelial meningiomas can lead to the rarely observed xanthomatous form. We describe the case of a posterior pyramid xanthomatous meningioma in a 2-year-old girl. After detailed neuroradiological evaluation, the histological diagnosis was confirmed with the aid of immunohistochemical evaluation. A critical case evaluation in the light of the more recent literature, the surgical strategy and technique, and an immunohistological hypothesis are reported.

    Objectives. Cardiovascular disease remains the major cause of death in SLE. We assessed the degree to which cardiovascular risk factors (CVRFs) and disease activity were associated with 2-year changes in measures of subclinical atherosclerosis. Methods. One hundred and eighty-seven SLE patients participating in a placebo-controlled trial of atorvastatin underwent multi-detector CT [for coronary artery calcium (CAC)] and carotid duplex [for carotid intima–media thickness (IMT) and carotid plaque] twice, 2 years apart. During the 2 years, patients were assessed every 3 months for CVRF. Both groups were combined for analysis, as atorvastatin did not differ from placebo in preventing progression of coronary calcium. We examined the correlation between these clinical measures and progression of CAC, IMT and plaque during the follow-up period. Results. In an analysis adjusting for age, gender and ethnicity, CAC progression was positively associated with total serum cholesterol measured over the 2-year period (P = 0.04) and smoking (P = 0.003). Carotid IMT progression was associated with systolic BP (P = 0.003), high-sensitivity CRP (hsCRP) (P = 0.013) and white blood cell (WBC) count (P = 0.029). Carotid plaque progression, defined as patients without carotid plaque at baseline with subsequent development of plaque at follow-up, was associated with systolic BP (P = 0.003), WBC count (P = 0.02), physician's global assessment (P = 0.05), blood lymphocyte count (P = 0.048), urine protein (P = 0.017) and duration of SLE (P = 0.019). Conclusion. Our data did not provide evidence of an association between measures of SLE disease activity (SLEDAI, anti-dsDNA, anti-phospholipid and treatment) and progression of subclinical atherosclerosis. Age and hypertension were associated with the progression of carotid IMT and plaque. Age, smoking and cholesterol were associated with progression of CAC. PMID:21875880

    Current information on the incidence and prevalence of bone metastases in women with breast cancer is scarce. This study examined the occurrence and predictors of bone metastases, as well as post-metastasis survival in a prospective cohort of Canadian women with breast cancer. We included women treated for early-stage (stage I, II, or III) breast cancer at the Henrietta Banting Breast Centre (HBBC) in Toronto, Canada between 1987 and 2000. Data were abstracted from medical records and pathology reports in the HBBC database; follow-up extended to end of data availability or August 31, 2015. Actuarial survival analyses provided cumulative incidence of bone metastases at 5, 10, and 15 years after breast cancer diagnosis. Kaplan-Meier curves describe breast cancer mortality. Regression models assessed patient, tumor, and treatment characteristics as predictors of bone metastases with all-cause mortality as a competing risk. Among 2097 women studied, the 5-, 10-, and 15-year probability of bone metastasis was 6.5, 10.3, and 11.3 % for the first recurrence, and 8.4, 12.5, and 13.6 % for any bone recurrence. At median follow-up (12.5 years), 13.2 % of patients had bone metastases. Median survival was 1.6 years following bone metastasis, and shorter if both bone and visceral metastases occurred. Advanced age and adjuvant treatment with tamoxifen were protective against bone metastasis. In this representative cohort of women diagnosed with early-stage breast cancer in Ontario, Canada, with long follow-up, the incidence of bone metastases was consistent with longitudinal studies from the United Kingdom, Denmark, and the US.

    The aim of this study was to estimate the incidence of anaphylaxis in the emergency department of a tertiary-care hospital, describe the clinical features and the management of the patients and determine those with mild manifestations. A retrospective study was conducted from 2005 to 2006 using anaphylaxis-related ICD-10 terms. Two different sets of criteria for the diagnosis of anaphylaxis were applied, first the criteria previously accepted by emergency practice, followed by the recent criteria set forth at the 2005 international meeting. Sixty-four patients fulfilled the previous criteria with an average incidence of 52.5 per 100,000 patients per year with a shift towards females in 2006. The most common presentations were cutaneous, followed by respiratory symptoms. Food allergy was the most common cause, especially prawn. After applying the recent criteria, 13 patients (20.4%) were excluded, which reduced the incidence to 42.2 per 100,000 patients per year. Long term follow up is suggested for the possible or mild cases that were re-categorized.

    Abstract The incidence trend of anaphylaxis in Asia is not well investigated. The aim of this study is to estimate the entire population-based incidence of anaphylaxis in Korea using a nationwide administrative database. Data over a 7-year period (2008–2014) was obtained from the Korean National Health Insurance (NHI) claims database which covers 97.9% of the entire Korean population. Using diagnosis codes from the International Classification of Diseases-10 for anaphylaxis (T78.0, T78.2, T80.5, and T88.6), we identified the annual number of patients who had visited any hospital with a primary diagnosis of anaphylaxis. Incidence rates were calculated using the population distribution data of all NHI beneficiaries. The incidence of anaphylaxis in Korea was 32.19 episodes per 100,000 person-years in 2014, which nearly doubled from 2008 (16.02 episodes per 100,000 person-years). The incidence of anaphylaxis increased continuously throughout these years regardless of gender and age groups (P for trend < 0.001). Female was significantly less predisposed than male (adjusted odds ratio [OR], 0.69; 95% confident interval [CI], 0.66–0.72; P < 0.001). The incidence was the lowest in 0 to 19 age group and the highest in 40 to 69 age group (adjusted OR, 2.41; 95% CI, 2.29–2.54; P < 0.001). In conclusion, we report the increasing time trend of anaphylaxis incidence rates using nationwide claims database for the first time in Asia. PMID:28151851

    ABO-incompatible intestinal transplantation has rarely been performed due to poor patient outcomes. Herein we present a case of successful ABO-incompatible intestinal transplantation with a 2-year follow-up. A 16-year-old female with a history of extensive bowel resection received an ABO-incompatible living donor bowel graft from her father (blood type AB graft into a type A recipient). Posttransplant immunosuppression consisted of an initial anti-CD20, plasmapheresis/intravenous immunoglobulin before transplantation, followed by an anti-thymocyte globulin (ATG) induction and splenectomy, and maintenance with tacrolimus and prednisone. Her postoperative course was remarkable for a single episode of rejection on day 14 which responded promptly to treatment with methyprednisolone and ATG. Three months after transplantation, the patient developed an abdominal abscess requiring open surgical drainage. No viral infections were encountered. Posttransplant anti-B antibody titers and anti-B7 donor-specific antibody levels remained low. At a 2-year follow-up, the patient showed a progressive weight gain of 5.0 kg. This case illustrates that ABO-incompatible living-related bowel transplantation is immunologically feasible and is associated with good outcomes for the recipient. The management of blood type antibodies and the use of adequate immunosuppression in the early period of the procedure may be the keys to the success of future cases.

    Earlier studies using voice-onset time (VOT) as the acoustic marker of contrastive voicing acquisition in English have differed widely in method and statistical procedures. Research in this area has shown three primary patterns of voicing acquisition for English stop consonants. One report indicates children demonstrate discrete voicing categories with adult-like VOT values as early as 2 years old. Other reports suggest a subperceptual distinction of the voicing contrast, followed by an exaggerated voicing contrast with evidence of more adult-like discrete categories by 3 years old. Still other reports suggest no distinction between the voicing categories until approximately 3 years. This work investigates voicing acquisition in three typically developing, English-speaking 2-year-old children. The subjects were recorded every 2 weeks for 4-6 months. Approximately 15-20 tokens were elicited for four target utterances containing initial /b p t d/. Frequency distribution, measures of central tendency, and skewness will be calculated for every recording session of each child. Discussion will focus on the development of contrastive VOT categories and their stability over time. These data will contribute to our understanding of laryngeal timing for English stop consonants in young children.

    Heat pipe performance data taken during the 8 1/2 years of flight of the OAO-C (Copernicus) spacecraft are presented. Three fixed conductance heat pipes (FCHP), each with different wicking concepts (axial groove, pedestal artery, and self-priming spiral artery), and one variable conductance heat pipe (VCHP) are onboard. Aluminum tubes (1/2 in. diameter) rolled into a 48 in. loop containing ultra high purity ammonia as the heat transfer fluid comprise all FCHP, whose purpose is to circumferentially isothermalize the central tube housing the telescope. The VCHP is a hot, non-wicked reservoir concept including a composite artery and methanol heat transfer fluid, and is used to maintain the temperature of the onboard processor. Flight thermal data analysis reveals that no degradation in performance occurred since launch and agrees well with pre-flight data; the onboard processor still shows an offset in control range of 4 F, and the pipes perform the same after 8 1/2 years in orbit.

    Purpose A large body of literature has indicated vowel space area expansion in infant-directed (ID) speech compared with adult-directed (AD) speech, which may promote language acquisition. The current study tested whether this expansion occurs in storybook speech read to infants at various points during their first 2 years of life. Method In 2 studies, mothers read a storybook containing target vowels in ID and AD speech conditions. Study 1 was longitudinal, with 11 mothers recorded when their infants were 3, 6, and 9 months old. Study 2 was cross-sectional, with 48 mothers recorded when their infants were 3, 9, 13, or 20 months old (n = 12 per group). The 1st and 2nd formants of vowels /i/, /ɑ/, and /u/ were measured, and vowel space area and dispersion were calculated. Results Across both studies, 1st and/or 2nd formant frequencies shifted systematically for /i/ and /u/ vowels in ID compared with AD speech. No difference in vowel space area or dispersion was found. Conclusions The results suggest that a variety of communication and situational factors may affect phonetic modifications in ID speech, but that vowel space characteristics in speech to infants stay consistent across the first 2 years of life.

    Objective To evaluate laparoscopic technical skill in surgical residents over a 2-year period. Design The laparoscopic technical skills of general surgical residents were evaluated using the MISTELS program. This provides an objective evaluation of laparoscopic skill, taking into account precision and speed. Setting Inanimate laparoscopic skills centre. Participants Ten general surgical residents (5 PGY1, 3 PGY2 and 2 PGY3 residents) who were required to complete 3 structured laparoscopic tasks. Outcome measures A composite score incorporating precision and timing was assigned to each task. The paired t-test was used to compare performance of each resident at the 2 levels of their residency training for each task. Linear regression analysis was used to correlate level of training and total score (sum of all tasks). Results Linear regression analysis demonstrated a highly significant correlation between level of training and total score (r = 0.82, p < 0.01). There was a significant increase in scores in the cutting and suturing task over the 2-year period (p < 0.01). Transferring skills did not improve significantly (p = 0.11). Conclusions Performance in the simulator improved over residency training and was correlated highly with postgraduate year. This simulator model is a valuable teaching tool for training and evaluation of basic laparoscopic tasks in laparoscopic surgery. PMID:10459330

    There has been some disquiet over the use of mercury containing restorative materials. The most commonly used alternative is composite resin but this has the potential disadvantage associated with wear and marginal leakage, which in turn, has proven to result in secondary caries and sensitivity. To overcome the shortcomings of a directly placed composite restoration, the glass-ionomer/composite open sandwich technique was introduced followed by the subsequent introduction of compomer systems. The aims of this study were to evaluate the wear and clinical performance of a control group of amalgam restorations compared with that of a group of posterior composite resin restorations fillings and a group of compomer/composite open sandwich restorations placed by a single general dental practitioner. The duration of the study was 2 years. One hundred and thirty three (71.4%) patients were successfully recalled and the wear and clinical performance of each restoration after 6, 12 and 24 months was measured, indirectly. There was no statistically significant difference recorded between the groups at 6 months or 1 year (p > 0.05). However, at the end of the 2-year study, there was a significantly lower rate of wear recorded for the control amalgam restorations compared with other two groups (p = 0.033). There was no statistically significant difference in wear recorded between the two groups of tooth-coloured restorations (p > 0.05). With regards to clinical performance of the restorations, occlusal and proximal contacts in each group of restoration remained satisfactory throughout the study.

  1. Breastfeeding and complementary feeding of children up to 2 years of age.

    Appropriate breastfeeding and complementary feeding practices are fundamental to children's nutrition, health, and survival during the first 2 years of life. The World Health Organization recommends exclusive breastfeeding until 6 months of age and continued breastfeeding for at least 2 years, along with the timely introduction of adequate amounts of complementary foods of suitable nutritional and microbiological quality. The amounts of energy and micronutrients required from complementary foods have been estimated as the difference between the total physiological requirements of these food components and the amounts transferred to the child in breast milk. Recommendations for the energy density of complementary foods and their frequency of feeding have also been proposed. Intakes of several micronutrients, including iron, zinc, calcium, selected B vitamins and (in some settings) vitamin A, remain problematic because commonly available, low-cost foods contain inadequate amounts of these nutrients to provide the shortfall in breast milk. Alternative strategies to provide these nutrients include adding animal source foods to the diet, providing fortified, processed complementary foods, administering micronutrient supplements, or offering some combination of these approaches. Advantages, disadvantages, and possible risks of these different strategies are discussed.

    OBJECT Alignment changes in the cervical spine that occur following surgical correction for thoracic deformity remain poorly understood. The purpose of this study was to evaluate such changes in a cohort of adults with thoracic deformity treated surgically. METHODS The authors conducted a multicenter retrospective analysis of consecutive patients with thoracic deformity. Inclusion criteria for this study were as follows: corrective osteotomy for thoracic deformity, upper-most instrumented vertebra (UIV) between T-1 and T-4, lower-most instrumented vertebra (LIV) at or above L-5 (LIV ≥ L-5) or at the ilium (LIV-ilium), and a minimum radiographic follow-up of 2 years. Sagittal radiographic parameters were assessed preoperatively as well as at 3 months and 2 years postoperatively, including the C-7 sagittal vertical axis (SVA), C2-7 cervical lordosis (CL), C2-7 SVA, T-1 slope (T1S), T1S minus CL (T1S-CL), T2-12 thoracic kyphosis (TK), apical TK, lumbar lordosis (LL), pelvic incidence (PI), PI-LL, pelvic tilt (PT), and sacral slope (SS). RESULTS Fifty-seven patients with a mean age of 49.1 ± 14.6 years met the study inclusion criteria. The preoperative prevalence of increased CL (CL > 15°) was 48.9%. Both 3-month and 2-year apical TK improved from baseline (p < 0.05, statistically significant). At the 2-year follow-up, only the C2-7 SVA increased significantly from baseline (p = 0.01), whereas LL decreased from baseline (p < 0.01). The prevalence of increased CL was 35.3% at 3 months and 47.8% at 2 years, which did not represent a significant change. Postoperative cervical alignment changes were not significantly different from preoperative values regardless of the LIV (LIV ≥ L-5 or LIV-ilium, p > 0.05 for both). In a subset of patients with a maximum TK ≥ 60° (35 patients) and 3-column osteotomy (38 patients), no significant postoperative cervical changes were seen. CONCLUSION Increased CL is common in adult spinal deformity patients with thoracic deformities

    Dystocia and assisted calving in primiparous heifers are persistent problems in beef herds, and incidence increases with increasing birth weight of calves. Plasma samples taken from 33 primiparous, 2-year-old, Angus heifers 2 days prior to parturition were analysed for oestrone sulphate concentration. Additional samples taken at 4, 6, 8 and 10 days prior to parturition were analysed for 17 of these heifers. At parturition, birth weight of the calf, post-partum live weight of the heifer, assistance at calving (n=6) and status of the calf (stillborn (n=4) vs. alive) were recorded. Maternal plasma oestrone sulphate concentration was stable from 10 to 4 days prior to parturition and increased between 4 and 2 days prior to parturition for non-assisted heifers. Maternal plasma oestrone sulphate concentration did not affect the probability of assistance at calving or stillbirth.

    The neonatal fate, and outcome at 2 years in a population of 96 premature babies born after no more than 28 weeks of amenorrhea is described. Mortality was directly influenced by the gestational age (< 26 WA = 52% vs. > or = 26 WA = 21.1%, p < 0.01) and the birth weight (< 1,000 g = 41.5% vs. > 1,000 g = 20%, p < 0.05). Two other factors with a harmful impact were identified: retarded growth (neonatal mortality doubled) and fetal multiplicity (increased fourfold). Investigation of the neonatal morbidity highlights the importance of respiratory, neurological and digestive problems. Assessment of the longer-term outcome has shown an 11.3 p. cent incidence of handicap. An estimation of the prognosis on the basis of gestational age is proposed.

    Liver cell transplantation into host organs like the spleen may possibly provide a temporary relief after extensive liver resection or severe liver disease or may enable treatment of an enzyme deficiency. With time, however, dedifferentiation or malignant transformation of the ectopically transplanted cells may be possible. Thus, in the present study syngenic fetal liver tissue suspensions were transplanted into the spleen of adult male rats and evaluated 2 years thereafter in comparison to orthotopic livers for histopathological changes and (as markers for preneoplastic transformation) for cytochrome P450 (P450) and glutathione S-transferase (GST) isoform expression. Because inducibility of P450 and GST isoforms may be changed in preneoplastic foci, prior to sacrifice animals were additionally treated either with beta-naphthoflavone, phenobarbital, dexamethasone, or the respective solvent. In the 2-year-old grafts more than 70% of the spleen mass was occupied by the transplant. The transplanted hepatocytes were arranged in cord-like structures. Also few bile ducts were present. Morphologically, no signs of malignancy were visible. With all rats, transplant recipients as well as controls, however, discrete nodular structures were seen in the livers. Due to age, both livers and transplants displayed only a low P450 2B1 and 3A2 and GST class alpha and mu isoform expression. No immunostaining for P450 1A1 was visible. At both sites, beta-naphthoflavone, phenobarbital, or dexamethasone treatment enhanced P450 1A1, P450 2B1 and 3A2, or P450 3A2 expression, respectively. No immunostaining for GST class pi isoforms was seen in the transplants. The livers of both transplant recipients and control rats, however, displayed GST pi-positive foci, corresponding to the nodular structures seen histomorphologically. Compared to the surrounding tissue, these foci also exhibited a more pronounced staining for GST class alpha and mu isoforms and a stronger inducibility of the P450 1A

    Background. In 2010, mass vaccination with a then-new meningococcal A polysaccharide–tetanus toxoid protein conjugate vaccine (PsA-TT, or MenAfriVac) was undertaken in 1- to 29-year-olds in Bamako, Mali. Whether vaccination with PsA-TT effectively boosts tetanus immunity in a population with heterogeneous baseline tetanus immunity is not known. We assessed the impact of PsA-TT on tetanus toxoid (TT) immunity by quantifying age- and sex-specific immunity prior to and 2 years after introduction. Methods. Using a household-based, age-stratified design, we randomly selected participants for a prevaccination serological survey in 2010 and a postvaccination survey in 2012. TT immunoglobulin G (IgG) antibodies were quantified and geometric mean concentrations (GMCs) pre- and postvaccination among all age groups targeted for vaccination were compared. The probability of TT IgG levels ≥0.1 IU/mL (indicating short-term protection) and ≥1.0 IU/mL (indicating long-term protection) by age and sex was determined using logistic regression models. Results. Analysis of 793 prevaccination and 800 postvaccination sera indicated that while GMCs were low pre–PsA-TT, significantly higher GMCs in all age–sex strata were observed 2 years after PsA-TT introduction. The percentage with short-term immunity increased from 57.1% to 88.4% (31.3-point increase; 95% confidence interval [CI], 26.6–36.0;, P < .0001) and with long-term immunity increased from 20.0% to 58.5% (38.5-point increase; 95% CI, 33.7–43.3; P < .0001) pre- and postvaccination. Conclusions. Significantly higher TT immunity was observed among vaccine-targeted age groups up to 2 years after Mali's PsA-TT mass vaccination campaign. Our results, combined with evidence from clinical trials, strongly suggest that conjugate vaccines containing TT such as PsA-TT should be considered bivalent vaccines because of their ability to boost tetanus immunity.

    BACKGROUND Racial disparities in allergic disease outcomes have been reported with African Americans suffering disproportionately compared to White individuals. OBJECTIVE Examine whether racial disparities are present as early as age 2 years in a racially diverse birth cohort in the Detroit metropolitan area. METHODS All children who were participants in a birth cohort study in the Detroit metropolitan area were invited for a standardized physician exam with skin prick testing and parental interview at age 2 years. Physicians made inquiries regarding wheezing and allergy symptoms and inspected for and graded any atopic dermatitis (AD). Skin testing was performed for Alternaria, cat, cockroach, dog, Dermatophagoides farinae (Der F), Short Ragweed, Timothy grass, egg, milk and peanut. Specific IgE was measured for these same allergens and total IgE was determined. RESULTS African American children (n=466) were more likely than White children (n=223) to have experienced any of the outcomes examined: at least 1 positive skin prick test from the panel of 10 allergens (21.7% versus 11.0%, p=0.001); at least one specific IgE ≥0.35 IU/mL (out of a panel of 10 allergens) (54.0% versus 42.9%, p=0.02); had AD (27.0% versus 13.5%, Chi-square p<0.001); and to ever have wheezed (44.9% versus 36.0%, p=0.03). African American children also tended to have higher total IgE (geometric means 23.4 IU/mL (95%CI 20.8, 27.6) versus 16.7 IU/mL (95%CI 13.6, 20.6 IU/mL), Wilcoxon Rank Sum p=0.004). With the exception of wheezing, the associations did not vary after adjusting for common social economic status variables (e.g.; household income), environmental variables (endotoxin; dog, cat and cockroach allergen in house dust) or variables that differed between the racial groups (e.g.; breastfeeding). After adjustment, the wheeze difference was ameliorated. CONCLUSIONS With disparities emerging as early as age 2 years, investigations into sources of the disparities should include the

    Objectives To assess 2-year durability of joint contracture correction following collagenase injections for Dupuytren's disease. Design Prospective cohort study. Setting Orthopaedic Department in Sweden. Participants Patients with palpable Dupuytren's cord and active extension deficit (AED) ≥30° in the metacarpophalangeal (MCP) and/or proximal interphalangeal (PIP) joint. A surgeon injected 0.80 mg collagenase into multiple cord parts and performed finger manipulation under local anaesthesia after 24–48 hours. A hand therapist measured joint contracture before and 5 weeks after injection in all treated patients. Of 57 consecutive patients (59 hands), 48 patients (50 hands) were examined by a hand therapist 24–35 months (mean 26) after injection. Five of the patients had received a second injection in the same finger within 6 months of the first injection. Outcome measures Primary outcome was proportion of treated joints with ≥20° worsening in AED from 5 weeks to 2 years. Results Between the 5-week and the 2-year measurements, AED had worsened by ≥20° in seven MCP and seven PIP joints (28% of the treated hands; all had received a single injection). Mean AED for the MCP joints was 54° before injection, 6° at 5 weeks and 9° at 2 years and for the PIP joints 30°, 13° and 16°, respectively. For joints with ≥10° contracture at baseline, mean (95 % CI) baseline to 2 years AED improvement was for MCP 49° (41–54) and for PIP 25° (17–32). No treatment-related adverse events were observed at the 2-year follow-up evaluation. Conclusions Two years after collagenase injections for Dupuytren's disease, improvement was maintained in 72% of the treated hands. Complete contracture correction was seen in more than 80% of the MCP but in less than half of the PIP joints. PMID:28298365

    Background The delta reverse shoulder replacement system was developed for the treatment of rotator cuff arthropathy so that the deltoid can substitute for the deficient rotator cuff. To evaluate the results of delta reverse shoulder replacement for functional improvement and complications in a consecutive series by a single surgeon over a period of six years with a minimum follow-up of 2 years. Methods The data were collected retrospectively from electronic theatre records. Over a period of 6 years (2006-2012), 46 cases that fulfilled the inclusion criteria were identified. There were 34 females and 12 males. The average age of patients was 76.2 years (range, 58 to 87 years). A single surgeon performed all procedures using the anterosuperior approach. The mean follow-up time was 49 months (range, 24 to 91 months). All cases had preoperative and postoperative Constant scores. We collected the data on indications, hospital stay, and change in the Constant score, complications, and reoperation rates. Results The main indication for surgery was rotator cuff arthropathy (52.2%), followed by massive rotator cuff tear (28.3%), osteoarthritis (8.7%), fractures (6.5%), and rheumatoid arthritis (4.3%). Also, 65.2% of the cases were referred by general practitioners, 26% of the cases were referred by other consultants, and 8.8% of the cases were already under the care of a shoulder surgeon. The average preoperative Constant score was 23.5 (range, 8 to 59). The average Constant score at the final follow-up was 56 (range, 22 to 83). On average, there was an improvement of 33 points in the Constant score. The improvement in the Constant score was significant (p < 0.001). We observed complications in four patients (8.6%). Three of four patients (6.5%) needed reoperation. The first complication was pulmonary embolism in the early postoperative period. The other complications included dissociation of the glenosphere from the metaglene, deltoid detachment, and stitch abscess

    Introduction. Noise as a common physical hazard may lead to noise-induced hearing loss, an irreversible but preventable disorder. Annual audiometric evaluations help detect changes in hearing status before clinically significant hearing loss develops. This study was designed to track hearing threshold changes during 2-year follow-up among tile and ceramic workers. Methods. This follow-up study was conducted on 555 workers (totally 1110 ears). Subjects were divided into four groups according to the level of noise exposure. Hearing threshold in conventional audiometric frequencies was measured and standard threshold shift was calculated for each ear. Results. Hearing threshold was increased during 2 years of follow-up. Increased hearing threshold was most frequently observed at 4000, 6000, and 3000 Hz. Standard threshold shift was observed in 13 (2.34%), 49 (8.83%), 22 (3.96%), and 63 (11.35%) subjects in the first and second years of follow-up in the right and left ears, respectively. Conclusions. This study has documented a high incidence of noise-induced hearing loss in tile and ceramic workers that would put stress on the importance of using hearing protection devices. PMID:24453922

    Primary cardiac tumours are rare in the paediatric age group. Bronchogenic cysts, although relatively rare, represent the most common cystic lesion of the mediastinum. Intracardiac bronchogenic cysts however, are extremely rare. The authors are unaware of any case previously reported in a Nigerian child and hence report the case of a 2-year-old boy for its rarity and interest. The boy was referred for evaluation of a cardiac murmur. Clinical, radiological and electrographic findings were suggestive of mild pulmonary stenosis or an atrial septal defect (ASD). 2-dimensional echocardiography however, revealed in addition to a small ASD, an intracardiac mass attached to the tricuspid valve. The mass was surgically removed and found on histology to be a bronchogenic cyst. Our experience highlights the importance of echocardiography in the evaluation of asymptomatic patients with cardiac murmurs, in whom a rare lesion might have otherwise been missed. PMID:22605814

    Chronic granulomatous disease (CGD) is a rare inherited immunodeficiency syndrome that results from abnormal nicotinamide adenine dinucleotide phosphate (NADPH) oxidase function. This defect leads to recurrent catalase-positive bacterial and fungal infections as well as associated granuloma formation. We review the case of a 2-year-old boy who presented with ascites and fever of an unknown origin as manifestations of CGD. Cultures were negative for infection throughout his course, and CGD was suspected after identification of granulomas on peritoneal biopsy. Genetic testing revealed a novel mutation in the CYBB gene underlying his condition. This paper highlights the importance of considering CGD in the differential diagnosis of fever of unknown origin and ascites in children.

Methods During Fall 2011 and Spring 2012, 441 students from 3 Minnesota community colleges enrolled in the Choosing Healthy Options in College Environments and Settings (CHOICES) Study and completed baseline assessments. Participants completed a baseline survey evaluating eating and activity patterns, sleep, and stress and measures of height, weight, waist circumference, and body fat. Results Participants were primarily female (68%), white (73%), with a mean age of 22.8 years and 66.2% reporting an annual income <$12,000. Almost half (47%) were overweight or obese. Young males appeared to engage the most in risky health behaviors and had higher levels of overweight or obesity, compared to young females.

    Analyses of elicited pantomime, primarily of English-speaking children, show that preschool-aged children are more likely to symbolically represent an object with gestures depicting an object's form rather than its function. In contrast, anecdotal reports of spontaneous gesture production in younger children suggest that children use multiple representational techniques. This study examined the spontaneous gestures of sixty-four 2-year-old Italian children and English-speaking Canadian children, primarily from middle-class Caucasian families. The Italian children produced twice as many gestures as Canadian children in a picture-naming task but produced a similar range of representational techniques. Two-year-olds were equally likely to produce gestures depicting function as form. These data suggest young children's communicative skills are supported by a symbolic capacity that reflects contextual communicative demands.

    The objective of this pharmacodynamic study was to longitudinally assess the activity of calcineurin during the first 2 years after lung transplantation. From March 2004 to October 2008, 107 patients were prospectively enrolled and their follow-up was performed until 2009. Calcineurin activity was measured in peripheral blood mononuclear cells. We report that calcineurin activity was linked to both acute and chronic rejection. An optimal activity for calcineurin with two thresholds was defined, and we found that the risk of rejection was higher when the enzyme activity was above the upper threshold of 102 pmol/mg/min or below the lower threshold of 12 pmol/mg/min. In addition, we report that the occurrence of malignancies and viral infections was significantly higher in patients displaying very low levels of calcineurin activity. Taken together, these findings suggest that the measurement of calcineurin activity may provide useful information for the management of the prevention therapy of patients receiving lung transplantation.

    The present article reports on a 2-year pilot study that evaluated the effectiveness of an intuitive eating program for patients in an eating disorder treatment center. Standardized measures of intuitive eating and eating disorder and psychological symptoms were administered. Psychotherapists and dietitians rated patients on the healthiness of their eating attitudes and behaviors. Preliminary findings indicated that patients can develop the skills of intuitive eating, and that the ability to eat intuitively is associated with positive treatment outcomes for each diagnostic category (i.e., anorexia nervosa, bulimia nervosa, and eating disorder not otherwise specified). We conclude by offering recommendations about how to implement intuitive eating training safely and effectively in inpatient and residential treatment programs.

    Drug development (DD) is a multidisciplinary process that spans the translational continuum, yet remains an understudied entity in medical schools and biomedical science institutes. In response to a growing interest and unmet need, we implemented a DD course series that details identification of viable molecular targets, clinical trial design, intellectual property, and marketing. Enrollment is open to faculty, postdoctoral trainees, and MD, PhD, and MS students. After 2 years, 37 students and 23 students completed the fall and spring courses, respectively. Pre/post-surveys demonstrated gained knowledge across course topics, with mean survey scores increased by 66% (p < 0.001) after each course. Lectures for each course were consistently rated highly, with a mean course rating of 4.1/5. Through this program, trainees will have a more innovative approach toward identification of therapeutic targets and modalities. Furthermore, they will learn to integrate technology and biomedical informatics to find creative solutions in the DD process.

    We compute the three-point temperature correlation function of the COBE Differential Microwave Radiometer (DMR) 2 year sky maps to search for evidence of non-Gaussian temperature fluctuations. We detect three-point correlations in our sky with a substantially higher signal-to-noise ratio than from the first-year data. However, the magnitude of the signal is consistent with the level of cosmic variance expected from Gaussian fluctuations, even when the low-order multipole moments, up to l = 9, are filtered from the data. These results do not strongly constrain most existing models of structure formation, but the absence of intrinsic three-point correlations on large angular scales is an important consistency test for such models.

    The 2-year test-retest reliability of the Psychopathy Checklist-Revised (PCL-R) was examined in 200 men and 25 women methadone patients. Stability of the PCL-R was generally good whether it was evaluated as a dichotomous or dimensional measure. Utilizing a diagnostic cutoff score of 25 or more the intraclass correlation coefficients (ICCs) were.48 for men and.67 for women. For the Total PCL-R score ICCs were.60 and.65 for men and women, respectively. Factor 1 was more reliably measured in women compared to men (.63 vs.43). For men, Factor 1 was significantly less reliable than Factor 2 or the Total score. For women, Factor 2 was significantly less reliable than the Total PCL-R score or Factor 1.

    AIM To analyze all windsurfing and kitesurfing (kiteboarding) injuries presented at our coastal hospital over a 2-year period. METHODS Twenty-five windsurfers (21 male; aged 31 ± 8 years) and 32 kitesurfers (23 male; aged 29 ± 11 years) presented at our hospital during the 2-year study period. Various injury data were recorded, including transport to hospital and treatment. After a median follow-up of 16 mo (range, 7-33 mo), 18 windsurfers (72%) and 26 kitesurfers (81%) completed questionnaires on the trauma mechanisms, the use of protective gear, time spent on windsurfing or kitesurfing, time to return to sports, additional injuries, and chronic disability. RESULTS Most patients sustained minor injuries but severe injuries also occurred, including vertebral and tibial plateau fractures. The lower extremities were affected the most, followed by the head and cervical spine, the upper extremities, and the trunk. The injury rates were 5.2 per 1000 h of windsurfing and 7.0 per 1000 h of kitesurfing (P = 0.005). The injury severity was the same between groups (P = 1.0). Less than 30% of the study population used protective gear. Kitesurfers had a higher number of injuries, and required transport by ambulance, inpatient hospital stay and operative treatment more often than windsurfers, but these differences were not statistically significant (P > 0.05). The median time to return to windsurfing and kitesurfing was 5 and 4 wk, respectively (P = 0.79). Approximately one-third of the patients in each group experienced chronic symptoms. CONCLUSION Kitesurfing results in a significantly higher injury rate than windsurfing in the same environmental conditions but the severity of the injuries does not differ. PMID:28032034

    Longitudinal studies of prospective predictors for pathological Internet use (PIU) in adolescents as well as its course are lacking. This three-wave longitudinal study was conducted within the framework of the European Union-funded project "Saving and Empowering Young Lives in Europe" over a 2-year period. The sample consisted of 1444 students at the baseline investigation (T0); 1202 students after 1 year (T1); and 515 students after 2 years (T2). Structured self-report questionnaires were administered at all three time points. PIU was assessed using the Young Diagnostic Questionnaire (YDQ). In addition, demographic (i.e., gender), social (i.e., parental involvement), psychological (i.e., emotional problems), and Internet use-related factors (i.e., online activities) were assessed as prospective predictors. The prevalence of PIU was 4.3 % at T0, 2.7 % at T1 and 3.1 % at T2. However, only 3 students (0.58 %) had persistent categorical PIU (YDQ score of ≥5) over the 2-year period. In univariate models, a variety of variables that have been previously identified in cross-sectional investigations predicted PIU at T2. However, multivariate regression demonstrated that only previous PIU symptoms and emotional problems were significant predictors of PIU 2 years later (adjusted R (2) 0.23). The stability of categorical PIU in adolescents over 2 years was lower than previously reported. However, current PIU symptoms were the best predictor of later PIU; emotional symptoms also predicted PIU over and above the influence of previous problematic Internet use. Both PIU symptoms and emotional problems may contribute to the vicious cycle that supports the perpetuation of PIU.

    The treatment of children with pervasive developmental disorders (PDD) has not been systematically assessed in French day-care units. In this prospective study, 11 children with a diagnosis of PDD were followed up for 2years in a day-care unit in the Marseille university hospital. The treatment they received is based on an initial assessment by the "Centre Ressources Autisme" (CRA PACA) and further included a continued observation of the child and an assessment of the child's abilities and needs. This treatment used various therapeutic approaches 10h weekly and also included parental counseling and coordinated work with schools. Treatment in our day-care unit can be categorized as eclectic, non-intensive therapy. It is based on methods such as TEACCH (Treatment and Education of Autistic and related Communication handicapped Children), Floor Time Play, speech and language therapy, developmental therapy, and psychotherapy. International studies on intensive behavioral therapies suggest that this treatment is superior to non-behavioral and/or non-intensive treatment. They suggest its efficiency is due both to the nature of the treatment (behavioral) and to its intensity (more than 25h a week). In this study, the CRA diagnosed children using the ADI and ADOS. The 11 children (mean age, 3years 5months) were tested twice, with the Vineland and CARS scales. The first assessment was on admission to the day hospital and the second was 2years later. The results showed developmental progress with a mean increase of 13.5 months at the Vineland Scale, and a decrease of the autism severity score on the CARS. The treatment presented here proves to be efficient; if compared to similar results in international studies, we obtained better results than their eclectic intensive or non-intensive treatment comparison group.

    Background Autologous serum skin test (ASST) and autologous plasma skin test (APST) are simple methods to diagnose autoimmune chronic urticaria. However, the association data of ASST or APST with disease severity and long-term outcome are still unclear. Objective The results of ASST and APST might be used to predict urticaria symptom severity and long-term outcomes among chronic spontaneous urticaria (CSU) patients. Methods We evaluated the prevalence of reactive ASST and APST in 128 CSU patients. The patients were characterized by 4 groups: negative, ASST positive, APST positive, and both ASST and APST positive. We observed remission rate among the CSU patients during 2 years. Results Forty-four of 128 CSU patients (34%) had negative autologous skin test. The CSU patients with positive ASST, positive APST, and both positive ASST and APST were 47 (37%), 6 (5%), and 31 (24%), respectively. No significant difference was found between the groups according to urticaria severity score (USS) and dermatology life quality index (DLQI). Mean wheal diameter of ASST showed positive correlation with DLQI. Also, mean wheal diameter of APST showed positive correlation with USS and DLQI. Both the positive ASST and APST groups had a high proportion of 4-fold dose of H1-antihistamine than the positive ASST (p = 0.03) and negative groups (p = 0.0009). The rate of remission over 2 years in the negative, positive ASST, positive APST, and both positive ASST and APST groups were 81.1%, 62.3%, 60%, and 46.1%, respectively. The urticaria remission rate in patients in the negative group was significantly higher compared with both positive ASST and APST groups (odds ratio, 5.0; 95% confidence interval, 1.61–15.44; p = 0.006). Conclusion ASST and APST results could predict remission rates among patients with CSU. Our results suggested investigating ASST and APST among CSU patients before starting treatment. PMID:27803883

    The aim of this study was to increase patients' adherence to the treatment of hypertension through the consultation training of nurses. Thirty-three nurses were included in the study. In the intervention group (IG), 19 nurses took part in a 3-day residential training course on the Stages of Change model, Motivational Interviewing and guidelines for cardiovascular prevention, and recruited 153 patients. Sixteen nurses in the control group (CG) recruited 59 patients. A decrease in systolic and diastolic blood pressure and total cholesterol was noticed in both groups over the 2 years. Heart rate (p = 0.027), body mass index (p = 0.019), weight (p = 0.0001), waist (p = 0.041), low-density lipoprotein-cholesterol (p = 0.0001), the waist-hip ratio (p = 0.024), and perceived stress (p = 0.001) decreased to any great extent only in the IG. After 2 years, 52.6% of the patients in the IG (p = 0.13) reached the target of ≤ 140/90 mmHg in blood pressure compared with 39.2% in the CG. For self-reported physical activity, there was a significant (p = 0.021) difference between the groups. The beneficial effects of the consultation training on patients' weight parameters, physical activity, perceived stress and the proportion of patients who achieved blood pressure control emphasize consultation training and the use of behavioural models in motivating patients to adhere to treatment.

    Emerging research highlights the role of self-regulation in the treatment of sexual offenders. Safe Offender Strategies (SOS) is a manualized sex offender treatment program that emphasizes the role of self-regulation and self-regulatory skills development in sex offender treatment, particularly for offenders with serious mental illness and intellectual/developmental disabilities. The current study involves 156 adult male sexual offenders in an inpatient psychiatric setting who received SOS treatment for a period ranging from 6 months to 1 year. Participants' baseline and treatment data were obtained from archival medical records describing 1 year pre-treatment and up to 2 years of treatment participation. Dependent variables included monthly count rates of verbal and physical aggression and contact and noncontact sexual offending, as well as sexual deviancy attitudes, self-regulatory ability, and cooperation with treatment and supervision, as measured by the Sex Offender Treatment Intervention and Progress Scale (SOTIPS). Data were examined via paired-samples t tests, regression, and multilevel modeling, examining the impact of overall percentage of SOS groups attended over time, comparing participants' baseline measures to data from 2 years of treatment. The impact of predicted risk was also evaluated. Significant treatment dose effects were identified for improvements in aggression, sexual offending, and indicators of treatment compliance and change. These findings suggest that the skills-based, self-regulation approach utilized in SOS may be effective in improving clients' aggressive and sexual behaviors, attitudes toward their offenses and treatment, and self-regulatory ability over time. Implications for further research and treatment generalizability are discussed.

    Objectives To assess pregnancies that could have been averted through improved access to contraceptive methods in the 2 years after delivery. Methods In this cohort study, we interviewed 403 postpartum women in a hospital in Austin, Texas who wanted to delay childbearing for at least 2 years. Follow-up interviews were completed at 3, 6, 9, 12, 18, and 24 months after delivery; retention at 24 months was 83%. At each interview, participants reported their pregnancy status and contraceptive method. At the 3- and 6-month interviews participants were also asked about their preferred contraceptive method 3 months in the future. We identified types of barriers among women unable to access their preferred method, and used Cox models to analyze the risk of pregnancy from 6 to 24 months after delivery. Results Among women interviewed 6 months postpartum (n=377), two thirds experienced a barrier to accessing their preferred method of contraception. By 24 months postpartum, 89 women had reported a pregnancy; 71 were unintended. Between 6 months postpartum and 24 months after delivery, 77 of 377 became pregnant (20.4%) with 56 (14.9%) lost to follow-up. Women who encountered a barrier obtaining their preferred method were more likely to become pregnant <24 months after delivery. They had a cumulative risk of pregnancy of 34% (95% CI: 0.25, 0.43) as compared to 12% (95% CI: 0.05, 0.18) for women with no barrier. All but three of the women reporting an unintended pregnancy had earlier expressed interest in using LARC or a permanent method. Conclusion In this study, most unintended pregnancies <24 months after delivery could have been prevented or postponed had women been able to access their desired long-acting and permanent methods.

    3,4-Methylenedioxymethamphetamine (MDMA) is associated with changes in neurocognitive performance. Recent studies in laboratory animals have provided additional support for the neurodegeneration hypothesis. However, results from animal research need to be applied to humans with caution. Moreover, several of the studies that examine MDMA users suffer from methodological shortcomings. Therefore, a prospective cohort study was designed in order to overcome these previous methodological shortcomings and to assess the relationship between the continuing use of MDMA and cognitive performance in incipient MDMA users. It was hypothesized that, depending on the amount of MDMA taken, the continued use of MDMA over a 2-year period would lead to further decreases in cognitive performance, especially in visual paired association learning tasks. Ninety-six subjects were assessed, at the second follow-up assessment: 31 of these were non-users, 55 moderate-users, and 10 heavy-users. Separate repeated measures analyses of variance were conducted for each cognitive domain, including attention and information processing speed, episodic memory, and executive functioning. Furthermore, possible confounders including age, general intelligence, cannabis use, alcohol use, use of other concomitant substances, recent medical treatment, participation in sports, level of nutrition, sleep patterns, and subjective well-being were assessed. The Repeated measures analysis of variance (rANOVA) revealed that a marginally significant change in immediate and delayed recall test performances of visual paired associates learning had taken place within the follow-up period of 2 years. No further deterioration in continuing MDMA-users was observed in the second follow-up period. No significant differences with the other neuropsychological tests were noted. It seems that MDMA use can impair visual paired associates learning in new users. However, the groups differed in their use of concomitant use of

    . Two patients in the monotherapy and none in the intensification group experienced viral breakthrough by Week 104. There were no reports of myopathy in either group. The mean changes in estimated glomerular filtration rate (eGFR), estimated using the Modification of Diet in Renal Disease (MDRD) formula, from baseline to Week 104 were +6.145 mL/min/1.73 m2 (p=0.0230) and +7.954 mL/min/1.73 m2 (p=0.0154) in the telbivudine monotherapy and tenofovir intensification groups, respectively. The incidence of serious AEs was four in the telbivudine monotherapy and two in the tenofovir intensification group. The main limitation of this study was limited sample size, which made the power of the observation low, and the absence of a comparative subgroup to assess the progression of patients with detectable HBV DNA without treatment intensification. Conclusions: Data from this 2-year roadmap study confirmed that telbivudine with add-on tenofovir was effective and well tolerated in patients with CHB. Telbivudine was associated with an improvement in eGFR from baseline in both the groups. PMID:27403192

    The carcinogenicity of ethyl tertiary-butyl ether (ETBE) was examined by oral administration using F344/DuCrlCrlj rats. Groups of 50 male and 50 female rats were given drinking water containing ETBE at doses of 0, 625, 2,500 or 10,000 ppm (w/w) for 104 weeks. No significant increase in the incidence of tumors was detected in any organ of either sex. Rat-specific non-neoplastic lesions were observed in the kidney: An increase in the severity of chronic progressive nephropathy was observed in the male and female 10,000 ppm groups, and increased incidences of urothelial hyperplasia of the pelvis and mineral deposition in the renal papilla were observed in the male 2,500 and 10,000 ppm groups. Besides these lesions, no treatment-related histopathological changes were observed in any organ or tissue in either sex. Thus, the present study demonstrated that a two year administration ETBE in the drinking water did not exert any carcinogenic effects in either male or female rats.

  17. Aberrations for Grazing Incidence Optics

    Saha, Timo T.

    2008-01-01

    Large number of grazing incidence telescope configurations have been designed and studied. Wolte1 telescopes are commonly used in astronomical applications. Wolter telescopes consist of a paraboloidal primary mirror and a hyperboloidal or an ellipsoidal secondary mirror. There are 8 possible combinations of Wolter telescopes. Out of these possible designs only type 1 and type 2 telescopes are widely used. Type 1 telescope is typically used for x-ray applications and type 2 telescopes are used for EUV applications. Wolter-Schwarzshild (WS) telescopes offer improved image quality over a small field of view. The WS designs are stigmatic and free of third order coma and, therefore, the PSF is significantly better over a small field of view. Typically the image is more symmetric about its centroid. As for the Wolter telescopes there are 8 possible combinations of WS telescopes. These designs have not been widely used because the surface equations are complex parametric equations complicating the analysis and typically the resolution requirements are too low to take full advantage of the WS designs. There are several other design options. Most notable are wide field x-ray telescope designs. Polynomial designs were originally suggested by Burrows4 and hyperboloid-hyperboloid designs for solar physics applications were designed by Harvey5. No general aberration theory exists for grazing incidence telescopes that would cover all the design options. Several authors have studied the aberrations of grazing incidence telescopes. A comprehensive theory of Wolter type 1 and 2 telescopes has been developed. Later this theory was expanded to include all possible combinations of grazing incidence and also normal incidence paraboloid-hyperboloid and paraboloid-ellipsoid telescopes. In this article the aberration theory of Wolter type telescopes is briefly reviewed.

    Experience makes a superior teacher. Sharing the details surrounding safety events is one of the best ways to help prevent their recurrence elsewhere. This approach requires an open, non-punitive environment to achieve broad benefits. The Hydrogen Incident Reporting Tool (www.h2incidents.org) is intended to facilitate the sharing of lessons learned and other relevant information gained from actual experiences using and working with hydrogen and hydrogen systems. Its intended audience includes those involved in virtually any aspect of hydrogen technology, systems and use, with an emphasis towards energy and transportation applications. The database contains records of safety events both publicly available and/or voluntarily submitted. Typical records contain a general description of the occurrence, contributing factors, equipment involved, and some detailing of consequences and changes that have been subsequently implemented to prevent recurrence of similar events in the future. The voluntary and confidential nature and other characteristics surrounding the database mean that any analysis of apparent trends in its contents cannot be considered statistically valid for a universal population. A large portion of reported incidents have occurred in a laboratory setting due to the typical background of the reporting projects, for example. Yet some interesting trends are becoming apparent even at this early stage of the database’s existence and general lessons can already be taken away from these experiences. This paper discusses the database and a few trends that have already become apparent for the reported incidents. Anticipated future uses of this information are also described. This paper is intended to encourage wider participation and usage of the incidents reporting database and to promote the safety benefits offered by its contents.

    Background Currently available treatments for Alzheimer’s disease (AD) can produce mild improvements in cognitive function, behavior, and activities of daily living in patients, but their influence on long-term survival is not well established. This study was designed to assess patient survival and drug efficacy following a 2-year galantamine treatment in patients with mild to moderately severe AD. Methods In this multicenter, double-blind study, patients were randomized 1:1 to receive galantamine or placebo. One primary end point was safety; mortality was assessed. An independent Data Safety Monitoring Board monitored mortality for the total deaths reaching prespecified numbers, using a time-to-event method and a Cox-regression model. The primary efficacy end point was cognitive change from baseline to month 24, as measured by the Mini-Mental State Examination (MMSE) score, analyzed using intent-to-treat analysis with the ‘last observation carried forward’ approach, in an analysis of covariance model. Results In all, 1,024 galantamine- and 1,021 placebo-treated patients received study drug, with mean age ~73 years, and mean (standard deviation [SD]) baseline MMSE score of 19 (4.08). A total of 32% of patients (661/2,045) completed the study, 27% (554/2,045) withdrew, and 41% (830/2,045) did not complete the study and were discontinued due to a Data Safety Monitoring Board-recommended early study termination. The mortality rate was significantly lower in the galantamine group versus placebo (hazard ratio [HR] =0.58; 95% confidence interval [CI]: 0.37; 0.89) (P=0.011). Cognitive impairment, based on the mean (SD) change in MMSE scores from baseline to month 24, significantly worsened in the placebo (−2.14 [4.34]) compared with the galantamine group (−1.41 [4.05]) (P<0.001). Functional impairment, based on mean (SD) change in the Disability Assessment in Dementia score (secondary end point), at month 24 significantly worsened in the placebo (−10.81 [18

    The incidence and contribution to total depression of the depressive symptoms of cognitive deficit and cognitive bias in prostate cancer (PCa) patients were compared from cohorts sampled during the first 2 years after diagnosis. Survey data were collected from 394 patients with PCa, including background information, treatments, and disease status, plus total scores of depression and scores for subscales of the depressive symptoms of cognitive bias and cognitive deficit via the Zung Self-Rating Depression Scale. The sample was divided into eight 3-monthly time-since-diagnosis cohorts and according to depression severity. Mean scores for the depressive symptoms of cognitive deficit were significantly higher than those for cognitive bias for the whole sample, but the contribution of cognitive bias to total depression was stronger than that for cognitive deficit. When divided according to overall depression severity, patients with clinically significant depression showed reversed patterns of association between the two subsets of cognitive symptoms of depression and total depression compared with those patients who reported less severe depression. Differences in the incidence and contribution of these two different aspects of the cognitive symptoms of depression for patients with more severe depression argue for consideration of them when assessing and diagnosing depression in patients with PCa. Treatment requirements are also different between the two types of cognitive symptoms of depression, and several suggestions for matching treatment to illness via a personalized medicine approach are discussed.

    There is a large geographical variability in prostate cancer incidence and mortality trends, mostly because of heterogeneity in control efforts across regions. We aimed to describe the time trends in prostate cancer incidence and mortality in Portugal, overall and by region, and to estimate the number of incident cases and deaths in 2020. The number of cases and incidence rates in 1998-2009 were collected from the Regional Cancer Registries. The number of deaths and mortality rates were obtained from the WHO mortality database (1988-2003 and 2007-2013) and Statistics Portugal (2004-2006; 1991-2013 by region). JoinPoint analyses were used to identify significant changes in trends in age-standardized incidence and mortality rates. Incidence and mortality predictions for 2020 were performed using Poisson regression models and population projections provided by Statistics Portugal. In Portugal, prostate cancer incidence has been increasing since 1998 (1.8%/year), with the exception of the North Region, with a decrease since 2006 (-3.2%/year). An overall mortality decline has been observed since 1997 (-2.2%/year), although there were two patterns of mortality variation at the regional level: one with an inflection point or significant variation in the rates and the other without significant variation. If these trends are maintained, ∼8600 incident cases and 1700 deaths may be expected to occur in Portugal in 2020. Despite the overall increasing incidence and decreasing mortality, there is a large heterogeneity across regions. Future studies should address regional differences in the trends of prostate specific antigen screening and in the effective management of prostate cancer.

    OBJECTIVE The purpose of this study was to assess prospectively the effects of midurethral sling surgery on sexual function and activity. STUDY DESIGN Sexual activity and function was assessed in 597 women with stress urinary incontinence who were enrolled in a randomized equivalence trial of retropubic compared with transobturator midurethral slings. Repeated measures analysis of variance was used to assess changes in Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire scores over a 2-year period. RESULTS Significant, similar improvements in sexual function were seen in both midurethral sling groups. Mean Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire scores increased from 32.8 at baseline to 37.6 at 6 months and 37.3 at 24 months (P < .0001). Dyspareunia, incontinence during sex, and fear of incontinence during sex each significantly improved after surgery. Preoperative urge incontinence was associated with abstinence after surgery (P = .02); postoperative urge incontinence negatively impacted sexual function (P = .047). CONCLUSION Midurethral sling surgery for stress urinary incontinence significantly improves sexual function, although coexistent urge incontinence has a negative impact. PMID:22840975

    An analogue of the periodogram method for unequally spaced data is presented with a view to resolving the frequency structure of the observations. The algorithm is explicitly based on the sequential least squares procedure. In particular, the key concept is that the with-in-plot spectral analysis can be augmented by the between-plot information to make inferences about common characteristics. It is also shown how the between-plot random variations can be incorporated into the multiple harmonic regression model. A detailed spectral analysis investigates the periodic fluctuations in four cardio-circulatory variables, measured by autorhythmometric observation by eight men at rest and extending over a time span of 2 years. The spectral curves show the existence of circadian and circaseptan rhythmicities. The amplitude modulation of the dian rhythm by circaseptan variation is assimilated with the rhythmicity of work during the week. The blood-pressure variables situate their maximum annual peak in the winter period. These quasi-periodic fluctuations appear to be related to the amount of physical activity performed in time by the subjects.

    Aims and method To evaluate whether involuntary out-patient commitment (OPC) in patients with severe mental disorder reduces their use of hospital services. This is a retrospective case-control study comparing a group of patients on OPC (n = 75) and a control group (n = 75) which was composed of patients whose sociodemographic variables and clinical characteristics were similar to those of the OPC group. Each control case is paired with an OPC case, so the control case must have an involuntary admission in the month that the index OPC case admission occurred. Emergency room visits, admissions and average length of hospital stay over a 2-year follow-up after the initiation of OPC were compared. Results No statistically significant evidence was found in the use of mental healthcare services between the two groups. Different reasons for admission found between the groups limit similarity when comparing the two. Clinical implications The findings cast doubt over the effectiveness of this legal measure to reduce emergency visits, the number of admissions and the length of stay in the hospital.

    The blood lead levels of a large number of US preschool children approach the value regarded as the upper limit of normal. To reduce the number of children whose levels increase into the range thought to be toxic, the antecedents and correlates of levels in the 0- to 25-micrograms/dL range must be identified. In a large longitudinal study of middle and upper-middle class children living in metropolitan Boston, we evaluated how well five sets of variables predicted children's blood lead levels at 2 years of age: environmental lead sources, mouthing activity, home environment/care giving, prior developmental status, and sociodemographic characteristics. A series of bivariate and multivariate analyses indicated that only environmental lead sources and, to a lesser extent, mouthing activity accounted for significant portions of the variance in blood lead levels. Environmental lead sources were not significantly related to the home environment/care-giving variables or to sociodemographic characteristics. The most promising approach for achieving community-wide reductions in children's blood lead levels is reduction in the amount of lead in the proximate environment.

    To determine the prevalence of Giardia genotypes in 12-24 month old dairy heifers, fecal specimens were collected from two farms each in Vermont, New York, Pennsylvania, Maryland, Virginia, North Carolina, and Florida. Specimens, cleaned of fecal debris and concentrated using CsCl density gradient centrifugation, were subjected to PCR and DNA sequence analysis. Prevalence of Giardia infection, ranged from 11% to 75% on 14 farms with an average prevalence of 36% (204 positive cattle out of 571 examined). DNA sequence analysis of the 16S rRNA gene revealed 91% of the 204 Giardia isolates were Assemblage E, and 9% were Assemblage A. The prevalence of these genotypes varied greatly from farm to farm, with four farms having exclusively Assemblage E Giardia. Overall, Assemblage E was present in 33% of all animals tested and Assemblage A was present in 3% of the animals. Thus, while many of the heifers were infected with a genotype that is not known to be infectious for humans, 1-2 year old heifers on 10 of 14 farms did harbor zoonotic Assemblage A Giardia. Therefore, heifers cannot be overlooked as a potential source of human infectious cysts in the environment, with some farms representing a much higher risk than others.

    A 1-year-old-female Yorkshire Terrier was referred to the Veterinary Teaching Hospital of the Autonomous University of Barcelona (VTH-UAB) (Spain) with a 6-month history of unilateral chronic proliferative conjunctivitis and intermittent vomiting and cough. Several medical and surgical treatment efforts to manage conjunctival lesions had resulted in no improvement of the clinical signs. Complete general and ophthalmic examinations revealed several proliferative 'wood-like' masses in the conjunctiva, oral cavity and an interscapular subcutaneous nodule. Conjunctival and buccal biopsies were performed as diagnostic procedures. A diagnosis of ligneous conjunctivitis was made on the basis of histopathology findings and clinical presentation. The only biochemical abnormalities found were severe proteinuria and low plasminogen activity in plasma. No other analytical abnormalities were observed. Topical treatment with heparin and anti-inflammatory and immunosuppressive drugs have controlled the ophthalmological clinical signs. To our knowledge, this is the first case report of a dog with plasminogen deficiency and ligneous conjunctivitis with a long survival period and 2-year follow-up.

    There is strong evidence of the positive role that youth engagement programs and policies play in creating resiliency and producing positive outcomes among youth populations, such as delaying or avoiding the onset of risk-taking behaviors. Research also suggests that achieving positive outcomes ideally includes influence from the individual, the family, the school, the community, and the field of public health (available in A Research Report and Recommendations for Ontario Public Health Association). The authors conducted a comprehensive evaluation of a 2-year pilot project designed to increase the application of engagement and resiliency theory, knowledge, and skills among public health professionals engaging students from Grades 6, 7, and 8 (11- to 14-year-olds). Qualitative methods assessed public health satisfaction with training, resources, and networking activities, whereas quantitative methods assessed changes in capacity with respect to youth engagement knowledge, awareness, confidence, and skills. The findings have helped shed light on public health professional needs concerning capacity and confidence to undertake youth engagement work. Key lessons learned about making youth engagement possible and effective for public health professionals are presented.

    Very little is known about cortical development in the first years of life, a time of rapid cognitive development and risk for neurodevelopmental disorders. We studied regional cortical and subcortical gray matter volume growth in a group of 72 children who underwent magnetic resonance scanning after birth and at ages 1 and 2 years using a novel longitudinal registration/parcellation approach. Overall, cortical gray matter volumes increased substantially (106%) in the first year of life and less so in the second year (18%). We found marked regional differences in developmental rates, with primary motor and sensory cortices growing slower in the first year of life with association cortices growing more rapidly. In the second year of life, primary sensory regions continued to grow more slowly, while frontal and parietal regions developed relatively more quickly. The hippocampus grew less than other subcortical structures such as the amygdala and thalamus in the first year of life. It is likely that these patterns of regional gray matter growth reflect maturation and development of underlying function, as they are consistent with cognitive and functional development in the first years of life.

    Posaconazole is a triazole antifungal agent used as adjuvant or salvage therapy for the treatment of zygomycosis, an invasive fungal infection associated with high mortality. Oral posaconazole absorption is highly variable. We describe the pharmacokinetics of oral posaconazole in a 2-year-old boy with rhino-cerebral-orbital zygomycosis. Seven days after induction therapy for acute lymphoblastic leukemia, he was brought to the emergency department because of left eyelid swelling and was admitted to the hospital. Zygomycosis was diagnosed 12 days later. After we conducted a literature search and consulted with antifungal drug experts, a triple-antifungal regimen consisting of liposomal amphotericin B, caspofungin, and posaconazole was started. Given the severity of the disease, we aimed for posaconazole plasma trough concentrations greater than 1.25 µg/ml; the dosage necessary to achieve this goal was posaconazole 200 mg 4 times/day. After a difficult 105-day stay in the hospital and stabilization of the fungal infection, the patient was discharged. Caspofungin was discontinued at time of discharge, but the patient continued to receive amphotericin B lipid complex 7.5 mg/kg/day intravenously and posaconazole 200 mg orally 4 times/day. This is one of the few case reports describing posaconazole pharmacokinetics in a child younger than 8 years. In patients with extensive zygomycosis, a triple-antifungal regimen, combined with therapeutic drug monitoring of posaconazole, may be helpful.

    The cosmic microwave background (CMB) is a unique probe of cosmological parameters and conditions. There is a connection between anisotropy in the CMB and the topology of the Universe. Adopting a universe with the topology of a 3-Torus, or a universe where only harmonics of the fundamental mode are allowed, and using 2-years of COBE/DMR data, we obtain constraints on the topology of the Universe. Previous work constrained the topology using the quadrupole component and the correlation function of the CMB. In this letter, we obtain more accurate results by using all multipole moments, avoiding approximations by computing their full covariance matrix. We obtain the best fit for a cubic toroidal universe of scale 7200h{sup -1} Mpc for n = 1. The data set a lower limit on the cell size of 4800h{sup -1} Mpc at 95% confidence and 6000h{sup -1} Mpc at 65% confidence. These results show that the most probable cell size would be around 1.2 times larger than the horizon scale, implying that the 3-Torus topology is no longer an interesting cosmological model.

    OBJECTIVES. We sought to evaluate the utility of partner notification for control of human immunodeficiency virus (HIV) infection and to identify subgroups in which it may be most effective. METHODS. All persons reported to be HIV-positive during a 2-year period were interviewed. Outcome measures included proportion of index patients cooperating; number of partners named, located, counseled, and tested; number of persons newly testing positive; and costs. RESULTS. Of 308 index patients, 244 (79%) cooperated. They named 890 partners; 499 (70%) of in-state partners were located. Of these, 154 (34%) had previously tested HIV-positive. Of 279 partners tested for the first time, 39 (14%) were HIV-positive. Injecting drug users were significantly more likely to cooperate than persons in other risk groups (93% vs 76%) and named more partners (median 4 vs 1). Women and persons choosing confidential testing were more likely to cooperate and named more partners. The estimated cost of the program was $62,500 per year. CONCLUSIONS. Partner notification identified a group with a high seroprevalence of HIV. It was not successful among populations that may be difficult to reach with other interventions. PMID:8214231

    Cognitive rehabilitation has shown beneficial effects on cognition in patients with schizophrenia, which may also help to improve negative symptoms due to overlapping pathophysiology between these two domains. To better understand the possible relationship between these areas, we conducted an exploratory analysis of the effects of Cognitive Enhancement Therapy (CET) on negative symptoms. Early course schizophrenia outpatients (n=58) were randomized to 2 years of CET or an Enriched Supportive Therapy (EST) control condition. Results revealed significant and medium-sized (d=0.61) differential improvements favoring CET in overall negative symptoms, particularly social withdrawal, affective flattening, and motor retardation. Neurocognitive improvement was associated with reduced negative symptoms in CET, but not EST patients. No relationships were observed between improvements in emotion processing aspects of social cognition, as measured by the Mayer-Salovey-Caruso Emotional Intelligence Test, and negative symptoms. CET represents an effective cognitive rehabilitation intervention for schizophrenia that may also have benefits to negative symptoms. Future studies specifically designed to examine negative symptoms during the course of cognitive rehabilitation are needed.

    We examined the ability of two 2-year-old children with limb deficiency to demonstrate grasp and release while using the cable-operated voluntary opening hook-hand and the externally powered single-site myoelectric Cookie Crusher system. The Cookie Crusher circuit is an electronic package that causes the prosthetic hand to open in response to muscle contraction and closes (as if crushing a cookie) when the muscle is relaxed. Both children were consistently good prosthetic wearers, beginning with their initial passive devices and progressing through their cable-operated hooks and hands. However, before they began to use the Cookie Crusher (Subject 1 at 25 months, Subject 2 at 30 months), neither had developed voluntary grasp or release in spite of 3 to 12 months' use of cable-operated voluntary opening prehensors. Both children developed a voluntary grasp and release for the first time within minutes of starting to use the Cookie Crusher. The more adept of the two children, a girl with a traumatic above-elbow amputation, showed prehensile function with the Cookie Crusher during play. The spontaneous use of the Cookie Crusher may be related to the predominance of associated reactions in young children. As children play bimanually, associated movements of the nondominant extremity often occur and, in the case of children with limb deficiencies fitted with Cookie Crusher prehensors, these associated reactions result in successful grasp and release. We will continue to follow the choice of effective control schemes in these children as they mature.

    Purpose The hypothesis of this study was that single-legged horizontal hop test ratios would correlate with IKDC, KOOS, and Marx activity level scores in patients 2 years after primary ACL reconstruction. Methods Individual patient-reported outcome tools and hop test ratios on 69 ACL reconstructed patients were compared using correlations and multivariable modeling. Correlations between specific questions on the IKDC and KOOS concerning the ability to jump and hop ratios were also performed. Results The triple-hop ratio was moderately but significantly correlated with the IKDC, KOOS Sports and Recreation subscale, and the KOOS Knee Related Quality of Life subscale, as well as with the specific questions related to jumping. Similar but weaker relationship patterns were found for the single-hop ratio and timed hop. No significant correlations were found for the Marx activity level or crossover-hop ratio. Multivariable modeling showed almost no significant additional contribution to predictability of the IKDC or KOOS subscores by gender, BMI, or the number of faults on either leg. Conclusions The triple-hop test is most significantly correlated with patient-reported outcome scores. Multivariable modeling indicates that less than a quarter of the variability in outcome scores can be explained by hop test results. This indicates that neither test can serve as a direct proxy for the other; however, assessment of patient physical function by either direct report using validated outcome tools or by the hop test will provide relatively comparable data.

    The prevalence of stunting remains high in low- and middle-income countries despite adoption of comprehensive nutrition interventions, particularly in low-income countries. In the present paper, we review current evidence on the acceptability and efficacy of small-quantity lipid-based nutrient supplements (SQ-LNS) on preventing stunting in children under 2 years, discuss the factors that affect their efficacy, highlight the implications of the current findings at pragmatic level and identify research priorities. Although the present paper is not a generic systematic review, we used a systematic approach to select relevant literature. The review showed that there is growing interest in the potential benefits of using SQ-LNS to prevent growth faltering. Acceptability studies showed that SQ-LNS are generally well accepted. However, results on the efficacy of SQ-LNS on improving linear growth or preventing growth faltering in infants and young children are still inconclusive. Factors that may affect efficacy include the duration of the trial, composition and dosage of SQ-LNS given, and baseline demographics and nutritional status of research participants. Future research should focus on controlled and long-term follow-up trials to obtain more conclusive results. In the long term, there will be need for studies to investigate how provision of SQ-LNS can be integrated with existing strategies to prevent stunting in low- and middle-income settings.

    Opsoclonus-myoclonus syndrome, also named Myoclonic Encephalopathy of Infants, Opsoclonus- Myoclonus Ataxia, Dancing Eyes - Dancing Feet Syndrome, Dancing Eyes Syndrome, Kinsbourne syndrome, is a rare, paraneoplastic or possibly post-viral chronic neurological disorder. The age of presentation ranges from 6 months to 3 years. In 50% of affected children the syndrome is associated with an underlying occult or clinically apparent neuroblastoma. In most patients the tumour is localized, small and well differentiated, with no NMYC gene copy number amplification. The syndrome may also occur after tumour resection or at relapse. The opsoclonus-myoclonus syndrome can occur in children without neuroblastoma, in such idiopathiccases, the onset of neurological symptoms is related to infection. It is assumed, that in idiopathic cases the syndrome could have developed in the course of neuroblastoma which had undergone a complete spontaneous regression. The most characteristic clinical features of opsoclonus-myoclonus syndrome are: opsoclonus, myoclonus, ataxia, irritability, mutism and sleep disturbances. The disease course is usually long-term with episodes of remission and relapses. Approximately 80% of children with opsoclonus-myoclonus syndrome suffer from mild to severe neurological handicaps, mainly cognitive impairment. The authors present a 2-year old boy with opsoclonus-myoclonus syndrome preceded by involution of prenatally documented retroperitoneal area tumour.

    Radian has used the Xerox 2-PHASE{trademark} Extraction technology at several facilities worldwide to remove VOCs and petroleum hydrocarbons from subsurface soils and groundwater. The use of high vacuum with 2-PHASE{trademark} causes greater forces to be applied to the subsurface than do other dual-phase methods. 2-PHASE{trademark} improves dewatering, increases vacuum and groundwater radii of influence, deepens vadose zone development, enhances vapor stripping of soil contamination, improves vaporflow, and expedites remediation timeframes. This paper describes the successful 2-year application of 2-PHASE{trademark} to, remediate soil and several groundwater contamination. Contamination occurred under a floor slab near a former solvent spray booth and several underground storage tanks. Contaminants were primarily chlorinated VOCs and mineral spirits ranging to 330 mg/kg in soil and 1,070 mg/L in groundwater. The 2-PHASE{trademark} system was installed in October 1993; business constraints necessitated the completion of remediation within two years. The system was modified and expanded to optimize the removal effectiveness and extend the area of influence. Subsurface soil data obtained 8 and 11 months into the remediation program were used with soil gas data to predict future soil concentrations. VOC concentrations in the soil and groundwater were reduced by over 95 percent, and remediation goals were met within 18 months following start of in situ 2-PHASE{trademark} remediation. The system has been decommissioned following agency and landowner approval.

    Following the changes in October 1990 in the payment system for children's dental treatment within the General Dental Service in the UK there has been widespread concern that repercussions would be felt in other branches of dentistry. The aim of this survey was to investigate the referral of children for specialist care to the Department of Child Dental Health in Newcastle upon Tyne after the changes in 1990, so that consultant clinics and the provision of advice and treatment could be targeted more effectively. Information was obtained from the patients' referral letters and from their hospital records between March 1991 and March 1993. There were 513 referrals (excluding those for orthodontic treatment, extractions under general anaesthesia and acute emergencies), the number more than doubling during the 2-year survey period. 83% of these patients lived within 15 miles of the hospital. 84% of these referrals were from general dental practitioners, and the greater proportion were from those who graduated within the previous 4 years. The most common reason for referral involved behaviour problems. Changes in the payment system that occurred in 1990 may have been a contributory factor in explaining these findings.

    We cross-correlate the COBE6 DMR 2 year sky maps with spatial templates from long-wavelength radio surveys and the far-infrared COBE DIRBE maps. We place an upper limit on the spectral index of synchrotron radiation βsynch < -2.9 between 408 MHz and 31.5 GHz. We obtain a statistically significant cross-correlation with the DIRBE maps, whose dependence on the DMR frequencies indicates a superposition of dust and free-free emission. The high-latitude dust emission (|b| > 30°) is well fitted by a single dust component with temperature T = 18+3-7 K and emissivity ν ∝ (υ/ν0)β with β = 1.9+3.0-0.5. The free-free emission is spatially correlated with the dust on angular scales larger than the 70 DMR beam, with rms variations 5.3±1.8 μK at 53 GHz and angular power spectrum p ∝ l-3. If this correlation persists to smaller angular scales, free-free emission should not be a significant contaminant to measurements of the cosmic microwave anisotropy at degree angular scales for frequencies above 20 GHz.

    1979-01-01

    This report presents the results of the first 2 years of a 4-year investigation of potential for artificial recharge and recharge methods that might be used to mitigate excessive aquifer depletion in Nebraska. A Quaternary sand-and-gravel aquifer near Aurora, Nebr., was recharged by injecting water through a well at a rate of approximately 730 gallons per minute for nearly 6 months. Total recharge was 530 acre-feet. Recharge was intermittent during the first 2 months, but was virtually continuous during the last 4 months. Buildup of the water level in the recharge well was 17 feet. The rate of buildup indicates that the well could have accepted water by gravity flow at more than 3,000 gallons per minute for at least 1 year. The cause of a continuing slow rise in water levels in the recharge well in contrast to nearly stable water levels in observation wells as close as 10 feet from the recharge well is as yet uncertain. The recharge water and the native ground water appeared to be chemically compatible. Infiltration rates from 24-foot-diameter surface impoundments ranged from 0.04 to 0.66 feet per day. The higher rates may have resulted in part from leakage down incompletely sealed holes that were drilled to install monitoring equipment. The investigation, including a report on the entire project, is scheduled for completion by 1980.

    The objective of this study was to evaluate the clinical wear behaviour of posterior, metal-free polymer crowns and to compare it with that of metal-ceramic crowns. After randomization, a total of 120 single crowns were set in posterior teeth. These 120 crowns were divided into three groups: 40 polymer crowns with a glass-fibre framework (group 1), 40 polymer crowns without framework stabilization (group 2) and 40 metal-ceramic crowns (control group). Wear was measured by use of gypsum replicas and a 3D laser scanner at baseline and after 2 years. Statistical analysis was performed by use of a mixed-effects regression model. The mean total wear of posterior single crowns was -19.0 mum (+/- 18.5 microm) in group 1, -24.3 microm (+/- 31.5 microm) in group 2 and -7.0 microm (+/- 8.8 microm) in the control group. Statistical analysis revealed the mean total wear of the polymer crowns in groups 1 (P < or = 0.01) and 2 (P < or = 0.01) was significantly greater than in the control group. No significant difference was detected between groups 1 and 2 (P = 0.58). Age, gender and opposing teeth had no significant effect on wear behaviour.

    The aim was to investigate injury risk factors in junior tennis players. Fifty-five players, 35 boys and 20 girls, answered a questionnaire about training habits, time of exposure, previous injuries and equipment factors. A battery of clinical tests and functional performance tests were also carried out. All tennis-related injuries that occurred during a 2-year period were identified and recorded. An injury was defined as an injury if it was impossible to participate in regular tennis training or playing matches during at least one occasion, a time loss injury. Potential injury risk factors were tested in a forward stepwise logistic regression model for injury. Thirty-nine players sustained totally 100 new and recurrent injuries. Injuries to the lower extremity were the most common ones (51%) followed by the upper extremity (24%) and the trunk (24%). Injured players performed more singles per week (P<0.0001) and played more tennis hours per year (P=0.016) than the uninjured players. Playing tennis more than 6 h/week was found to be a risk factor for back pain. A previous injury regardless of location was identified as an injury risk factor, and a previous injury to the back was a risk factor for back pain.

    Our objective was to conduct a process evaluation of the CHOICES (Choosing Healthy Options in College Environments and Settings) study, a large, randomized, controlled trial designed to prevent unhealthy weight gain in young adults (aged 18-35) attending 2-year community colleges in the USA. The 24-month intervention consisted of participation in an academic course and a social networking and support website. Among intervention participants, completion rates for most course activities were >80%, reflecting a high level of dose received. Course retention and participant satisfaction were also high. Engagement results, however, were mixed with less than half of participants in the online and hybrid sections of the course reporting that they interacted with course materials ≥3 h/week, but 50-75% reporting that they completed required lessons 'all/very thoroughly'. Engagement in the website activities was also mixed with more than half of intervention participants logging onto the website during the first month, but then declining to 25-40% during the following 23 months of the intervention. Intervention engagement is a challenge of online interventions and a challenge of working with the young adult age group in general. Additional research is needed to explore strategies to support engagement among this population, particularly for relatively long intervention durations.

    Objective To investigate the sex- and age-specific incidence of healthcare-register-recorded anorexia nervosa (AN) and other eating disorders (OED) in a complete birth cohort, and assess whether incidence varies by diagnostic period and (sub-) birth cohort. Method We used the actuarial method and Poisson models to examine the incidence of AN and OED from 1987–2009 (when individuals were 8–30 years) for a cohort of 2.3 million individuals (48.7% female) born from 1979–2001 in Sweden, identified using Swedish registers. Results For both sexes, incidences of AN and OED increased considerably for diagnostic periods after 2000, but differed little by birth cohort. In 2009, AN incidence in the peak age category was 205.9 cases/100,000 persons (95% CI: 178.2, 233.5) for females (14–15 years), versus 12.8 cases/100,000 (95% CI: 5.6, 20.1) for males (12–13 years). OED incidence in the peak age category was 372.1 cases/100,000 (95% CI: 336.4, 407.9) for females (16–17 years), versus 22.2 cases/100,000 (95% CI: 13.3, 31.1) for males (14–15 years). Discussion Our finding of an increase in healthcare register-recorded eating disorders for diagnostic periods after 2000 likely reflects improved detection and expanded register coverage in Sweden. The peak of eating disorder incidence in adolescence, which began unexpectedly early for AN in males, suggests the importance of vigilance for signs of AN in young boys and early primary prevention efforts. Waiting until later could miss critical windows for intervention that could prevent disorders from taking root. PMID:26769444

    Purpose. To assess the safety profile of ranibizumab 0.5 mg in patients with neovascular age-related macular degeneration (nAMD) in routine clinical practice. Methods. This 2-year, multicentre, observational study was conducted to capture real-world early practice and outcomes across Europe, shortly after European licensing of ranibizumab for nAMD. Being observational in nature, the study did not impose diagnostic/therapeutic interventions/visit schedule. Patients were to be treated as per the EU summary of product characteristics (SmPC) in effect during the study. Key outcome measures were incidence of selected adverse events (AEs), treatment exposure, bilateral treatment, compliance to the EU SmPC, and best-corrected visual acuity (BCVA) over 2 years. Results. 755 of 770 patients received treatment. Ranibizumab was generally well tolerated with low incidence of selected AEs (0%-1.9%). Patients received 6.2 (mean) injections and 133 patients received bilateral treatment over 2 years. Protocol deviation to treatment compliance was reported in majority of patients. The observed decline in mean BCVA (Month 12, +1.5; Month 24, -1.3 letters) may be associated with undertreatment as suggested by BCVA subgroup analysis. Conclusion. The EPICOHORT study conducted in routine clinical practice reinforces the well-established safety profile of ranibizumab in nAMD. In early European practice it appeared that the nAMD patients were undertreated.

    The replication of grazing incidence optics is reviewed. Electroform and epoxy replication are described and compared. It is concluded that for light weight and deep nesting, replication has a distinct advantage over direct production. The resolution of optics produced in this manner is however, limited to about 10 arc seconds; a typical value is 40 arc seconds. Epoxy replicated pieces tend to have better optical figures than electroformed optics, but the latter can be made thinner to make more deeply nested systems.

    Although aggression is part of daily life in psychiatric units for adolescents, empirical data on its prevalence are sparse. Only few studies have described prevalence of aggressive incidents in adolescent psychiatric wards, and data in forensic psychiatric care are even more limited. Available studies reported high prevalence rates of aggression, ranging from 0.4 to 2.4 incidents of aggression per day across (forensic) child and adolescent psychiatric units. Between 27 and 78 % of all admitted youth committed an aggressive act. In this study, we collected systematically registered data of all aggressive incidents from the first 2 years (2010-2012) on a newly established forensic adolescent psychiatric unit, which used a formal aggression management program embedded in the social competence model, which is based on early intervention in the 'chain of behavior' to prevent any further escalation. The inclusion of also minor aggressive incidents is unique in the literature and the clinical relevance is highlighted. A mean of one incident a day took place, with each adolescent involved in at least one incident. Notably, 1.7 aggressive incidents per month made seclusion of restraint use necessary. Based on the social competence theory, the aggression management model suggests intervening early in the cascade of aggression, in order to prevent further escalation and reduce the need for intrusive interventions. Evidence supported that aggression is a contextual event, as external factors clearly influence the incidence of aggression. Aggression management should be built on both relational and structural security.

    The AltiKa altimeter flying onboard the French/Indian SARAL satellite provides the first opportunity to examine Ka-band measurements of sea surface height, significant wave height and ocean surface wind speed. In this presentation we provide the results from our global calibration/validation analysis of the AltiKa measurements, with an emphasis on near real-time applications of interest to both EUMETSAT and NOAA. Traditional along-track SSHA, and single as well as dual-satellite crossover assessments of the AltiKa performance are be provided. Unique aspects of the AltiKa mission such as improved along-track resolution, reduced ionospheric path delay corrections, mission-specific wind speed and sea state bias corrections, and sensitivity to liquid moisture and rain are also explored. In February 2014, a major update to the ground processing was introduced. "Patch-2" improved the way wind speed was derived from altimeter backscatter, as suggested by Lillibridge et al. (1). The backscatter attenuation is now derived from the radiometer measurements via neural network algorithms, which also determine the wet tropospheric correction. We emphasize these improvements in our analysis. After 2 years in flight, SARAL/AltiKa is already providing a significant contribution to the constellation of operational radar altimetry missions, demonstrating the large benefits of high-rate Ka-band altimetry.

    Background and purpose Persistent postsurgical pain is a well-recognized problem after various types of surgery such as amputation and thoracotomy. The prevalence of persistent pain, and the extent to which it involves neuropathic pain, is highly dependent on the type of surgery. We investigated the prevalence of, characteristics of, and risk factors for persistent pain 1–2 years after shoulder replacement. Patients and methods A questionnaire was sent to patients who underwent primary shoulder replacement between April 2011 and April 2012, and whose data were recorded in the Danish Shoulder Arthroplasty Register. Patients who had undergone reoperation or bilateral replacements were excluded. Persistent pain was defined as constant or daily pain within the last month, which interfered much or very much with daily activities. Multivariate logistic regression was used to assess risk factors. Results 538 patients were available for analysis. The prevalence of persistent pain was 22% (CI: 18–25), and the prevalence of presumed neuropathic pain was 13% (CI: 10–16). Persistent pain was more frequent in fracture patients (29%) than in osteoarthritis patients (16%), while the prevalence of neuropathic pain was similar. Severe pain during the first postoperative week increased the risk of persistent pain. Risk also increased with hemiprosthesis (as compared to total prosthesis) in osteoarthritis patients, and with previous osteosynthesis and pain elsewhere in fracture patients. Interpretation Persistent pain after shoulder replacement is a daily burden for many patients. Further studies should address patient and prosthesis selection, postoperative pain management, and follow-up of these patients. PMID:25409254

    Objective To study the characteristics of a sample of suicide victims from the Athens Greater Area using the psychological autopsy method for the first time in Greece. Methods We studied all recorded cases of completed suicide for the 2-year time period November 2007-October 2009 collecting data from the victims' forensic records as well as from the completion of a psychological autopsy questionnaire. Results 335 persons were recorded as suicide victims. We contacted relatives of 256 victims interviewing those of 248 of them (96.9%). The differences regarding sex, marital and employment status between our sample and the general population were statistically significant (p<0.001). The male/female ratio was 3:1. Comparatively more victims were divorced, separated or single and a greater proportion were pensioners or unemployed. 26.0% of the victims had history of prior attempts (64.4% once, 20.3% twice and 15.3% more times). 42.6% were taking psychiatric medication-significantly more women than men according to blood tests; 14.2% had been hospitalized in a psychiatric clinic the year prior to their death. 84.8% have deceased at the place of suicide and 15.2% died in the hospital; 80.3% died indoors and 19.7% outdoors. Men died primarily by hanging or shooting by a firearm while women preferred jumping from height instead (p<0.001). As many as 48.8% had expressed their intention to die to their relatives; 26.6% left a suicide note. Conclusion Our study has shown that the psychological autopsy method is applicable and widely accepted yielding results comparable to the international literature. Specific parameters associated with suicide have been studied for the first time in Greece. PMID:25866522

    Four groups of 100 male and 100 female rats were exposed to ultrafine Kevlar fibrils at concentrations of 0, 2.5, 25, and 100 fibrils/cc for 6 hr/day, 5 days/week for 2 years. One group was exposed to 400 fibrils/cc for 1 year and allowed to recover for 1 year. At 2.5 fibrils/cc, the lungs had normal alveolar architecture with a few dust-laden macrophages (dust cell response) in the alveolar airspaces. At 25 fibrils/cc, the lungs showed a dust cell response, slight Type II pneumocyte hyperplasia, alveolar bronchiolarization, and a negligible amount of collagenized fibrosis in the alveolar duct region. At 100 fibrils/cc, the same pulmonary responses were seen as at 25 fibrils/cc. In addition, cystic keratinizing squamous cell carcinoma (CKSCC) was found in 4 female rats, but not in male rats. Female rats had more prominent foamy alveolar macrophages, cholesterol granulomas, and alveolar bronchiolarization. These pulmonary lesions were related to the development of CKSCC. The lung tumors were derived from metaplastic squamous cells in areas of alveolar bronchiolarization. At 400 fibrils/cc following 1 year of recovery, the lung dust content, average fiber length, and the pulmonary lesions were markedly reduced, but slight centriacinar emphysema and minimal collagenized fibrosis were found in the alveolar duct region. One male and 6 female rats developed CKSCC. The lung tumors were a unique type of experimentally induced tumors in the rats and have not been seen as spontaneous tumors in man or animals. Therefore, the relevance of this type of lung tumor to the human situation is minimal.

    The incidence of melanoma has been increasing steadily in many countries since 1960, but the underlying mechanism causing this increase remains elusive. The incidence of melanoma has been linked to the distance to frequency modulation (FM) broadcasting towers. In the current study, the authors sought to determine if there was also a related link on a larger scale for entire countries. Exposure-time-specific incidence was extracted from exposure and incidence data from 4 different countries, and this was compared with reported age-specific incidence of melanoma. Geographic differences in melanoma incidence were compared with the magnitude of this environmental stress. The exposure-time-specific incidence from all 4 countries became almost identical, and they were approximately equal to the reported age-specific incidence of melanoma. A correlation between melanoma incidence and the number of locally receivable FM transmitters was found. The authors concluded that melanoma is associated with exposure to FM broadcasting.

  16. Actuarial considerations on genetic testing.

    In the UK the majority of life insurers employ relatively liberal underwriting standards so that people can easily gain access to life assurance cover. Up to 95% of applicants are accepted at standard terms. If genetic testing becomes widespread then the buying habits of the public may change. Proportionately more people with a predisposition to major types of disease may take life assurance cover while people with no predisposition may take proportionately less. A model is used to show the possible effect. However, the time-scales are long and the mortality of assured people is steadily improving. The change in buying habits may result in the rate of improvement slowing down. In the whole population, the improvement in mortality is likely to continue and could improve faster if widespread genetic testing results in earlier diagnosis and treatment. Life insurers would not call for genetic tests and need not see the results of previous tests except for very large sums assured. In the UK, life insurers are unlikely to change their underwriting standards, and are extremely unlikely to bring in basic premium rating systems that give discounts on the premium or penalty points according to peoples genetic profile. The implications of widespread genetic testing on medical insurance and some health insurance covers may be more extreme. PMID:9304671

    Background: In the United States alone, millions of athletes participate in sports with potential for head injury each year. Although poorly understood, possible long-term neurological consequences of repetitive sports-related concussions have received increased recognition and attention in recent years. A better understanding of the risk factors for concussion remains a public health priority. Despite the attention focused on mild traumatic brain injury (mTBI) in football, gaps remain in the understanding of the optimal methodology to determine concussion incidence and position-specific risk factors. Purpose: To calculate the rates of concussion in professional football players using established and novel metrics on a group and position-specific basis. Study Design: Case-control study; Level of evidence, 3. Methods: Athletes from the 2012-2013 and 2013-2014 National Football League (NFL) seasons were included in this analysis of publicly available data. Concussion incidence rates were analyzed using established (athlete exposure [AE], game position [GP]) and novel (position play [PP]) metrics cumulatively, by game unit and position type (offensive skill players and linemen, defensive skill players and linemen), and by position. Results: In 480 games, there were 292 concussions, resulting in 0.61 concussions per game (95% CI, 0.54-0.68), 6.61 concussions per 1000 AEs (95% CI, 5.85-7.37), 1.38 concussions per 100 GPs (95% CI, 1.22-1.54), and 0.17 concussions per 1000 PPs (95% CI, 0.15-0.19). Depending on the method of calculation, the relative order of at-risk positions changed. In addition, using the PP metric, offensive skill players had a significantly greater rate of concussion than offensive linemen, defensive skill players, and defensive linemen (P < .05). Conclusion: For this study period, concussion incidence by position and unit varied depending on which metric was used. Compared with AE and GP, the PP metric found that the relative risk of concussion for

    Background Most published studies on injuries in the ballet dancer focus on the lower extremity. The rigors of this activity require special training and care. By understanding prevalence and injury pattern to the musculoskeletal system, targeted prevention and treatment for this population can be developed. Purpose To determine the incidence and prevalence of musculoskeletal injuries in ballet. Study Design Systematic review; Level of evidence, 4. Methods A systematic review registered with PROSPERO was performed using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Level 1 through 4 evidence studies reporting incidence of musculoskeletal injuries in male and female ballet dancers were included, with the numbers and types of injuries extracted from each. Injury rates were recorded and calculated based on professional status, sex, and nature of injury. Incidence was defined as number of injuries sustained over a specific time. Prevalence was defined as proportion of subjects with an injury at a given point in time. Results The studies analyzed reported injury incidence or prevalence in more than 1365 amateur and 900 professional dancers. The mean age was 16.2 years among amateur and 27.0 years among professional dancers. The incidence of injury among amateur dancers was 0.99 and 1.09 injuries per 1000 dance hours in males and females, respectively; 75% of injuries were overuse, with similar rates among males and females. In professional dancers, the incidence of injury was 1.06 and 1.46 injuries per 1000 dance hours in males and females, respectively, and 64% of female injuries were overuse, compared with 50% in males (P < .001). Only 3 studies provided prevalence data, including 62% prevalence of lumbosacral pain, 58% painful snapping hip, and 29% patellofemoral pain. Lower extremity injuries comprised 66% to 91% of all injuries, with the foot and ankle accounting for 14% to 57%. Conclusion The overall incidence of injury

    We had an opportunity to perform replantation of both legs on a 2-year-old girl, and our decision to perform replantation rather than amputation surgery was carefully made taking her age, degree of crushing injury, ischaemic time and level of the amputation into consideration. Painstakingly designed rehabilitation treatments were continuously performed on this girl from the early stage after the operation, and the treatments were comprised of four parts; that is, flexion and extension exercise for the ankle in order to prevent it from stiffness or contracture, functional electrical stimulation (FES) in order to prevent muscular atrophy on the lower extremities, muscle strengthening exercise for the lower extremities, and electrical stimulation to regenerate the damaged nerves and to prevent muscular atrophy from occurring. For an objective assessment of the postoperative conditions, total active motion angles of the ankle joint were measured, and also EMG and NCV were conducted at the end of the first month as well as at the end of the 6th month. Total active motion angles of the ankle joint were increased progressively as time went on, from 15 to 60 degrees on the right and from 10 to 45 degrees on the left. NCV did not show any sensation or response from motor nerves, or amplitude decreased considerably 1 month after the operation; however, at the end of the 6th month conditions improved a great deal with both amplitude and latency. And most muscles that did not show any signals on EMG or showed less than normal at the end of the first month after the operation eventually recovered at the end of the 6th month. The patient had no particular difficulties in walking after 6 months or rather she started running in small steps showing her legs functioning superbly. An infant with both of lower extremities amputated is quite a rare case. We believe that the replantation surgery was successful due to the fact that carefully selected preoperative factors were taken into

    The aim of this study was to evaluate the burden of hip fractures, which occurred in the French region of Picardie, in 1992, among 1103 women and 356 men, whether the fractures occurred at home or in a community (i.e., patients who depended on a collective service). The data are part of the PICAROS study, which was designed to assess prospectively the outcome of patients as judged by clinical, economical, and quality of life factors. Patients and/or proxies were questioned during the 2nd or 3rd week following the fracture, and again at 3, 6, 12, and 24 months after the fracture. The survey was conducted by home interview. Recruitment criteria were: 1) all patients with a hip fracture as defined by the International Classification of Disease (ICD); 2) 20 years of age and over; 3) admitted to one of the 34 surgical units from the region, public and private, and had an operation or not. Patients with metastatic or myelomatous fractures or fractures on prothesis device were not included. For the present analysis, patients under 50 years of age were excluded. Among people aged 50 years and over, 3% of the general population lived in a community; 32% of hip fractures were from a community. Patients in a community, aged 60-69, had 15 times more risk of having a hip fracture than subjects of the same age at home. The excess risk decreased with age and stabilized over 85 years of age at two to threefold. During the 24 month follow-up, 394 women and 173 men died. Among those surviving, 87% were interviewed at 2 years. We analysed seven classes of complications, according to the ICD: (1) pressure sores and blisters; (2) pulmonary infections; (3) urinary infections; (4) surgical complications; (5) orthopedic complications; (6) thrombosis and embolisms; and (7) secondary hip fractures. Patients coming from a community had a higher risk of mortality, pressure sores, surgical complications, and pulmonary and urinary infections. From an economical perspective, the

    Background By September 2015, a total of 29 states and Washington, D.C., were participating in Medicaid expansions under the Affordable Care Act. We examined whether Medicaid expansions were associated with changes in insurance coverage, health care use, and health among low-income adults. Methods We compared changes in outcomes during the 2 years after implementation of the Medicaid expansion (2014 and 2015) relative to the 4 years before expansion (2010 through 2013) in states with and without expansions, using data from the National Health Interview Survey. The sample consisted of 60,766 U.S. citizens who were 19 to 64 years of age and had incomes below 138% of the federal poverty level. Outcomes included insurance coverage, access to and use of medical care in the past 12 months, and health status as reported by the respondents. Results A total of 29 states and Washington, D.C., expanded Medicaid by September 1, 2015. In year 2 after implementation, uninsurance rates were reduced in expansion states relative to nonexpansion states (difference-in-differences estimate, -8.2 percentage points; P<0.001) and rates of Medicaid coverage were increased (difference-in-differences estimate, 15.6 percentage points; P<0.001). Expansions were not associated with significant changes in the likelihood of a doctor visit or overnight hospital stay or health status as reported by the respondent. However, as compared with nonexpansion states, expansion states had a decrease in reports of inability to afford needed follow-up care (difference-in-differences estimate, -3.4 percentage points; P=0.002) and in reports of worry about paying medical bills (difference-in-differences estimate, -7.9 percentage points; P=0.002) and an increase in reports of medical care being delayed because of wait times for appointments (difference-in-differences estimate, 2.6 percentage points; P=0.02). Conclusions Medicaid expansion was associated with increased insurance coverage and access to care

    Background We investigated the clinical results and early complications after lateral unicompartmental knee arthroplasty (UKA) using the Zimmer unicompartmental high-flex knee (ZUK) prosthesis with a minimum follow-up of 2 years. Methods Twenty-seven patients (30 cases) who underwent lateral UKA with the ZUK prosthesis between January 2011 and February 2014 were selected for this study. The mean age of the patients was 63.3 years at the time of surgery, and the mean followup was 3 years and 2 months (range, 24 to 48 months). A retrospective investigation method was used to evaluate the clinical and radiographic results with use of the Knee Society (KS) clinical rating system and plain radiography. Results The mean KS pain score was improved from 17.9 points (range, 10 to 30 points) preoperatively to 40.5 points (range, 30 to 45 points) at the final follow-up (p < 0.001). The mean KS knee score and function score significantly increased from 63.2 points (range, 48 to 70 points) and 68.6 points (range, 35 to 80 points), respectively, preoperatively to 86.0 points (range, 74 to 95 points) and 92.4 points (range, 60 to 100 points), respectively, at the final follow-up (p < 0.001). The mean range of motion of the knee was recovered from 127.1° (range, 110° to 135°) preoperatively to 131.6° (range, 120° to 135°) at the final follow-up. The mean tibiofemoral angle changed from 6.2° of valgus (range, 0.1° to 11.4° of valgus) preoperatively to 3.4°of valgus (range, 0.2° to 9.5° of valgus) at the final follow-up. The overall results classified based on the KS knee score were "excellent" in 21 cases and "good" in 8 cases. Revision total knee arthroplasty was required in one case because of consistent pain on the medial side of the knee after surgery. Conclusions The early clinical results of lateral UKA using the ZUK prosthesis were satisfactory for improvement of pain, knee score, function score, and recovery of knee motion. Therefore, the lateral UKA could be a

    Patients may find bronchoscopy without sedation unpleasant. There is some evidence that patient satisfaction correlates with amnesia for the procedure. For several years we have used doses of midazolam sufficient to put patients lightly asleep hoping to produce complete amnesia. We looked at practical aspects of this technique over a 2-year period. We studied 337 consecutive patients. They were 219 men and 118 women of mean age 63 +/- 12.4 (SD). Sixty-seven patients were aged 75 years or over and the eldest was 86. Sixty-three patients were already hospital inpatients but the remainder were seen as day cases. Midazolam was given by slow i.v. injection over several minutes until the patient was judged to be lightly asleep. Patients were given supplemental oxygen (3 l min-1) and monitored by ECG and pulse oximetry. A note was made of the time at which they awakened, defined as when nursing staff felt the patients were awake enough to have a cup of tea and toast. Patients were asked if they had any memory of the procedure both on awakening and when seen a few days later to discuss the results. The procedures were carried out in a well-staffed Day Case Unit with a recovery area. The mean dose of midazolam used was 10.8 mg (mean +/- SD = 0.16 +/- 0.095 mg kg-1). The midazolam was given over a median of 4 min (range 1-15 min). Patients took 59 +/- 45 min (mean +/- SD) to wake up. Twenty-eight patients were given flumazanil to reverse the sedation (11 for concern over bleeding following biopsies, three for desaturation during and three after procedure, four as they were frail, two as they were restless, two as they were hypotensive after procedure and three for miscellaneous reasons). Only nine patients could remember any part of the procedure. Incremental doses of midazolam given slowly until patients are lightly asleep almost invariably produce complete amnesia for bronchoscopy. This is a safe technique but patients need careful monitoring and may require reversal of

    Pregnancy weight gain may lead to long-term increases in maternal BMI for some women. The objective of this study was to examine maternal body weight change 1y-2y postpartum, and to compare classifications of 2y weight retention with and without accounting for 1y-2y weight gain. Early pregnancy body weight (EPW, first trimester) was measured or imputed, and follow-up measures obtained before delivery, 1 year postpartum (1y) and 2 years postpartum (2y) in an observational cohort study of women seeking prenatal care in several counties in upstate New York (n = 413). Baseline height was measured; demographic and behavioral data were obtained from questionnaires and medical records. Associations of 1y-2y weight change (kg) and 1y-2y weight gain (≥2.25 kg) with anthropometric, socioeconomic, and behavioral variables were evaluated using linear and logistic regressions. While mean ± SE 1y-2y weight change was 0.009 ± 4.6 kg, 1y-2y weight gain (≥2.25 kg) was common (n = 108, 26%). Odds of weight gain 1y-2y were higher for overweight (OR(adj) = 2.63, CI(95%) = 1.43-4.82) and obese (OR(adj) = 2.93, CI(95%) = 1.62-5.27) women than for women with BMI <25. Two year weight retention (2y-EPW ≥2.25 kg) was misclassified in 38% (n = 37) of women when 1y-2y weight gain was ignored. One year weight retention (1YWR) (1y-EPW) was negatively related to 1y-2y weight change (β(adj) ± SE = -0.28 ± 0.04, P < 0.001) and weight gain (≥2.25 kg) (OR(adj) = 0.91, CI(95%) = 0.87-0.95). Relations between 1y weight retention and 1y-2y weight change were attenuated for women with higher early pregnancy BMI. Weight change 1y-2y was predicted primarily by an inverse relation with 1y weight retention. The high frequency of weight gain has important implications for classification of postpartum weight retention.

    Longitudinal studies investigating vitamin B12 and folate status of mothers and their offspring will provide a better understanding of intergenerational nutrition. During pregnancy and 2 years (2y) after delivery, we measured plasma vitamin B12 and folate concentrations in 118 women [aged (mean ± s.d.) 22.9 ± 3.9y] who attended a rural (n = 68) or an urban (n = 50) antenatal clinic in Pune, India. Cord blood vitamin B12 and folate were measured, and when the child was 2y total homocysteine (tHcy) was also measured. Demographic and diet measurements were recorded using standard methods. Pregnancy plasma vitamin B12 concentration at 34 weeks was low [median (25th, 75th), 115 (95, 147) pm]; 75% had low status (<150 pm). Plasma folate was high (mean ± s.d., 33 ± 21 nm); one had a folate concentration <7 pm. Cord plasma vitamin B12 and folate concentrations were higher than and positively associated with maternal concentrations. In stepwise regression, higher child vitamin B12 at 2y was predicted (total R 2 15.7%) by pregnancy vitamin B12 (std β 0.201, R 2 7.7%), current consumption of cow's milk (std β 0.194, R 2 3.3%) and whether breast feeding was stopped before 2y (std β -0.234 R 2 7.2%). Child's 2y tHcy concentration was high (11.4 ± 3.6 μm) and predicted by lower pregnancy vitamin B12 (std β -0.206, R 2 4.1%), lack of vitamin supplementation (std β -0.256, R 2 5.6%) in pregnancy and whether currently breastfed (std β 0.268, R 2 8.4%). Low maternal vitamin B12 status in pregnancy and prolonged breast-feeding results in disturbed one-carbon metabolism in offspring at 2y. Supplementation of women of child-bearing age, particularly during pregnancy and lactation, may improve the homocysteine status of these children.

    The reported incidence of ARDS is highly variable (2.5%–19% of intensive care unit (ICU) patients) and varies depending on study patient population used. We undertook a 6-month, prospective study to determine the incidence and outcome of ARDS in a UK adult University Hospital ICU. 344 patients were admitted during the study period, of these 43 (12.5%) were determined to have ARDS. Patients with ARDS had increased mortality at 28 days and 2 years post-diagnosis, and there was under-recognition of ARDS in both medical records and death certificattion. Our findings have implications for critical care resource planning. PMID:27552782

    ♦ Background: The use of pH-neutral peritoneal dialysis (PD) fluids low in glucose degradation products (GDP) may better preserve the peritoneal membrane and have fewer systemic effects. The effects of conversion from conventional to neutral-pH, low-GDP PD fluids in prevalent patients are unclear. Few studies on the role of neutral-pH, low-GDP PD have studied residual renal function, ultrafiltration, peritonitis incidence and technique failure, transport characteristics, and local and systemic markers of inflammation in prevalent PD patients. ♦ Methods: In a multi-center open-label randomized clinical trial (RCT), we randomly assigned 40 of 78 stable continuous ambulatory PD (CAPD) and automated PD (APD) patients to treatment with bicarbonate/lactate, neutral-pH, low-GDP PD fluid (Physioneal; Baxter Healthcare Corporation, Deerfield, IL, USA) and compared them with 38 patients continuing their current standard lactate-buffered PD fluid (PDF) (Dianeal; Baxter Healthcare Corporation, Deerfield, IL, USA) during 2 years. Primary outcome was residual renal function (RRF) and ultrafiltration (UF) during peritoneal equilibration test (PET); peritonitis incidence was a secondary outcome. Furthermore, clinical parameters as well as several biomarkers in effluents and serum were measured. ♦ Results: During follow-up, RRF did not differ between the groups. In the Physioneal group ultrafiltration (UF) during PET remained more or less stable (-20 mL [confidence interval (CI):-163.5 - 123.5 mL]; p = 0.7 over 24 months), whereas it declined in the Dianeal group (-243 mL [CI: -376.6 to -109.4mL]; p < 0.0001 over 24 months), resulting in a difference of 233.7mL [95% CI 41.0 - 425.5 mL]; p = 0.017 between the groups at 24months. The peritonitis rate was lower in the Physioneal group: adjusted odds ratio (OR) 0.38 (0.15 - 0.97) p = 0.043. No differences were observed between the 2 groups in peritoneal adequacy or transport characteristics nor effluent markers of local

    The aim of the study was to analyze changes in functional adjustment from childhood to 2 years after the first episode of psychosis (FEP) in patients with early-onset schizophrenia spectrum disorders (SSD) and affective psychoses (AFP) and a good or intermediate level of premorbid adjustment. We followed 106 adolescents (aged 12-17 years) with FEP for 2 years after recruitment. Premorbid adjustment in childhood was assessed in 98 patients with the childhood subscale of the Cannon-Spoor Premorbid Adjustment Scale (c-PAS). Global functioning was assessed 2 years after the FEP with the Children's Global Assessment Scale (c-GAS) or the Global Assessment of Functioning scale (GAF), as appropriate. Functional deterioration was defined as a downward shift in the level of functional adjustment from childhood to 2 years after the FEP. In patients with good or intermediate premorbid adjustment, functional deterioration was observed in 28.2 % (26.5 % of the AFP group, 29.4 % of the SSD group). Longer duration of untreated psychosis (Beta = 0.01; P = 0.01) and higher symptom severity at the FEP, as measured with the Clinical Global Impression Scale (Beta = 1.12; P = 0.02), significantly predicted the presence of functional deterioration, accounting for 21.4 % of the variance. Irrespective of diagnosis (SSD or AFP), almost one-third of adolescents with FEP and good or intermediate premorbid adjustment showed functional deterioration from the premorbid period to 2 years after the FEP.

    OBJECT Regional cervical sagittal alignment (C2-7 sagittal vertical axis [SVA]) has been shown to correlate with health-related quality of life (HRQOL). The study objective was to examine the relationship between cervical and thoracolumbar alignment parameters with HRQOL among patients with operative and nonoperative adult thoracolumbar deformity. METHODS This is a multicenter prospective data collection of consecutive patients with adult thoracolumbar spinal deformity. Clinical measures of disability included the Oswestry Disability Index (ODI), Scoliosis Research Society-22 Patient Questionnaire (SRS-22), and 36-Item Short-Form Health Survey (SF-36). Cervical radiographic parameters were correlated with global sagittal parameters within the nonoperative and operative cohorts. A partial correlation analysis was performed controlling for C-7 SVA. The operative group was subanalyzed by the magnitude of global deformity (C-7 SVA ≥ 5 cm vs < 5 cm). RESULTS A total of 318 patients were included (186 operative and 132 nonoperative). The mean age was 55.4 ± 14.9 years. Operative patients had significantly worse baseline HRQOL and significantly larger C-7 SVA, pelvic tilt (PT), mismatch between pelvic incidence and lumbar lordosis (PI-LL), and C2-7 SVA. The operative patients with baseline C-7 SVA ≥ 5 cm had significantly larger C2-7 lordosis (CL), C2-7 SVA, C-7 SVA, PI-LL, and PT than patients with a normal C-7 SVA. For all patients, baseline C2-7 SVA and CL significantly correlated with baseline ODI, Physical Component Summary (PCS), SRS Activity domain, and SRS Appearance domain. Baseline C2-7 SVA also correlated with SRS Pain and SRS Total. For the operative patients with baseline C-7 SVA ≥ 5 cm, the 2-year C2-7 SVA significantly correlated with 2-year Mental Component Summary, SRS Mental, SRS Satisfaction, and decreases in ODI. Decreases in C2-7 SVA at 2 years significantly correlated with lower ODI at 2 years. Using partial correlations while controlling for

    The incidence of hypertension was determined among 10,173 patients of general practices in southwestern Ontario studied from 1978 to 1982. For both sexes the incidence of hypertension rose with increasing age. The incidence was higher among men than among women until age 50, after which it was similar for the two sexes. Obesity was positively associated with incidence for both sexes. In men this association diminished significantly with increasing age. The similar trend in women fell just short of statistical significance. In men but not women heavy alcohol consumption was positively related to the incidence of hypertension. However, the broad definition of this variable may have obscured a relation in women. Among men the effect of obesity on the incidence of hypertension was less for heavy drinkers than for light drinkers. Smoking was not related to the incidence of hypertension in either sex.

    Acquired hemophilia A is a severe bleeding disorder caused by an autoantibody to factor VIII. Previous reports have focused on referral center patients and it is unclear whether these findings are generally applicable. To improve understanding of the disease, a 2-year observational study was established to identify and characterize the presenting features and outcome of all patients with acquired hemophilia A in the United Kingdom. This allowed a consecutive cohort of patients, unbiased by referral or reporting practice, to be studied. A total of 172 patients with a median age of 78 years were identified, an incidence of 1.48/million/y. The cohort was significantly older than previously reported series, but bleeding manifestations and underlying diseases were similar. Bleeding was the cause of death in 9% of the cohort and remained a risk until the inhibitor had been eradicated. There was no difference in inhibitor eradication or mortality between patients treated with steroids alone and a combination of steroids and cytotoxic agents. Relapse of the inhibitor was observed in 20% of the patients who had attained first complete remission. The data provide the most complete description of acquired hemophilia A available and are applicable to patients presenting to all centers.

    The United States is in the midst of an unprecedented drug epidemic. Illicit use of prescription medicine, predominantly opioids, has become one of the nation's fastest-growing drug problems. We have conducted a retrospective review of prescription opioid fatalities in New York City (NYC) prior to the introduction of a 2013 law intended to curtail prescription drug abuse. Over the 2 years of our study, there were 1286 chemical intoxication fatalities in NYC. Of these, 547 (42.5%) were associated with prescription opioids (6.5/100,000 population). Methadone was most frequently encountered followed by oxycodone. Only 36.7% of decedents had a valid opioid prescription. Of non-opioid medications associated with the prescription opiate deaths, benzodiazepines were the most frequently encountered (68.4%), and alprazolam (35.1%) was most common. Though prescribers have no control over drug diversion they should be cognizant of the urgent public health concern regarding prescription opioid abuse and associated fatalities and attempt to identify doctor shoppers and limit prescription of these potent drugs to those with a legitimate need for pain control. They also need to be aware of the high incidence of fatalities due to combined opioid and benzodiazepine use/abuse and refrain from prescribing them in tandem.

    Cortical thickness (CT) is related to normal development and neurodevelopmental disorders. It remains largely unclear how the characteristic patterns of CT evolve in the first 2 years. In this paper, we systematically characterized for the first time the detailed vertex-wise patterns of spatial distribution, longitudinal development, and hemispheric asymmetries of CT at 0, 1, and 2 years of age, via surface-based analysis of 219 longitudinal magnetic resonance images from 73 infants. Despite the dynamic increase of CT in the first year and the little change of CT in the second year, we found that the overall spatial distribution of thin and thick cortices was largely present at birth, and evolved only modestly during the first 2 years. Specifically, the precentral gyrus, postcentral gyrus, occipital cortex, and superior parietal region had thin cortices, whereas the prefrontal, lateral temporal, insula, and inferior parietal regions had thick cortices. We revealed that in the first year thin cortices exhibited low growth rates of CT, whereas thick cortices exhibited high growth rates. We also found that gyri were thicker than sulci, and that the anterior bank of the central sulcus was thicker than the posterior bank. Moreover, we showed rightward hemispheric asymmetries of CT in the lateral temporal and posterior insula regions at birth, which shrank gradually in the first 2 years, and also leftward asymmetries in the medial prefrontal, paracentral, and anterior cingulate cortices, which expanded substantially during this period. This study provides the first comprehensive picture of early patterns and evolution of CT during infancy.

    The objective of this prospective clinical follow-up was to evaluate the 2-year clinical performance of a nanofilled resin composite in class II restorations. The restorations were made with and without intermediary layer of a nanofilled flowable resin composite studied in an intraindividual comparison. Each participant received at least two, as similar as possible, class II restorations of the nanofilled resin composite. One restoration of each pair (54) was chosen at random to be restored with an intermediary layer with flowable nanofilled resin composite. The other was restored without. The restorations were evaluated with slightly modified US Public Health Services criteria at baseline, 1, and 2 years. Ninety-two restorations, 46 pairs, were evaluated at 2 years. A prediction of the caries risk showed that 22 of the evaluated 48 patients were considered as high-risk patients. Two failures were observed, one in each group, resulting in a 2.2% failure rate. No statistical difference was seen between the restorations restored with and without layer of flowable resin composite. The nanofilled resin composite showed very good surface characteristics and color match, which did not change significantly during the follow-up period. The nanofilled resin composite showed a good clinical performance with a 2.2% failure rate after 2 years. No differences were observed between the restorations with and without the nanofilled flowable resin intermediary layer.

    Purpose: Sacral insufficiency (SI) fractures can occur as a late side effect of pelvic radiation therapy. Our goal was to determine the incidence, risk factors, and clinical course of SI fractures in patients treated with preoperative chemoradiation for rectal cancer. Materials and Methods: Between 1989 and 2004, 562 patients with non-metastatic rectal adenocarcinoma were treated with preoperative chemoradiation followed by mesorectal excision. The median radiotherapy dose was 45 Gy. The hospital records and radiology reports of these patients were reviewed to identify those with pelvic fractures. Radiology images of patients with pelvic fractures were then reviewed to identify those with SI fractures. Results: Among the 562 patients, 15 had SI fractures. The 3-year actuarial rate of SI fractures was 3.1%. The median time to SI fractures was 17 months (range, 2-34 months). The risk of SI fractures was significantly higher in women compared to men (5.8% vs. 1.6%, p = 0.014), and in whites compared with non-whites (4% vs. 0%, p = 0.037). On multivariate analysis, gender independently predicted for the risk of SI fractures (hazard ratio, 3.25; p = 0.031). Documentation about the presence or absence of pain was available for 13 patients; of these 7 (54%) had symptoms requiring pain medications. The median duration of pain was 22 months. No patient required hospitalization or invasive intervention for pain control. Conclusions: SI fractures were uncommon in patients treated with preoperative chemoradiation for rectal cancer. The risk of SI fractures was significantly higher in women. Most cases of SI fractures can be managed conservatively with pain medications.

    Purpose: To investigate the incidence and local control of internal mammary lymph node metastases (IMN+) in patients with clinical N2 or N3 locally advanced breast cancer. Methods and Materials: We retrospectively reviewed the records of 809 breast cancer patients diagnosed with advanced nodal disease (clinical N2-3) who received radiation treatment at our institution from January 2000 December 2006. Patients were considered IMN+ on the basis of imaging studies. Results: We identified 112 of 809 patients who presented with IMN+ disease (13.8%) detected on ultrasound, computed tomography (CT), positron emission tomography/CT (PET/CT), and/or magnetic resonance imaging (MRI) studies. All 112 patients with IMN+ disease received anthracycline and taxane-based chemotherapy. Neoadjuvant chemotherapy (NCT) resulted in a complete response (CR) on imaging studies of IMN disease in 72.1% of patients. Excluding 16 patients with progressive disease, 96 patients received adjuvant radiation to the breast or the chest wall and the regional lymphatics including the IMN chain with a median dose of 60 Gy if the internal mammary lymph nodes normalized after chemotherapy and 66 Gy if they did not. The median follow-up of surviving patients was 41 months (8-118 months). For the 96 patients able to complete curative therapy, the actuarial 5-year IMN control rate, locoregional control, overall survival, and disease-free survival were 89%, 80%, 76%, and 56%. Conclusion: Over ten percent of patients with advanced nodal disease will have IMN metastases on imaging studies. Multimodality therapy including IMN irradiation achieves excellent rates of control in the IMN region and a DFS of more than 50% after curative treatment.

    This report describes the findings and recommendations resulting from the Department of Homeland Security (DHS) Incident Management Simulation Workshop held by the DHS Advanced Scientific Computing Program in May 2004. This workshop brought senior representatives of the emergency response and incident-management communities together with modeling and simulation technologists from Department of Energy laboratories. The workshop provided an opportunity for incident responders to describe the nature and substance of the primary personnel roles in an incident response, to identify current and anticipated roles of modeling and simulation in support of incident response, and to begin a dialog between the incident response and simulation technology communities that will guide and inform planned modeling and simulation development for incident response. This report provides a summary of the discussions at the workshop as well as a summary of simulation capabilities that are relevant to incident-management training, and recommendations for the use of simulation in both incident management and in incident management training, based on the discussions at the workshop. In addition, the report discusses areas where further research and development will be required to support future needs in this area.

    Traffic congestion is a major operational problem on urban freeways. In the case of recurring congestion, travelers can plan their trips according to the expected occurrence and severity of recurring congestion. However, nonrecurring congestion cannot be managed without real-time prediction. Evaluating the efficiency of intelligent transportation systems (ITS) technologies in reducing incident effects requires developing models that can accurately predict incident duration along with the magnitude of nonrecurring congestion. This paper provides two statistical models for estimating incident delay and a model for predicting incident duration. The incident delay models showed that up to 85% of variation in incident delay can be explained by incident duration, number of lanes affected, number of vehicles involved, and traffic demand before the incident. The incident duration prediction model showed that 81% of variation in incident duration can be predicted by number of lanes affected, number of vehicles involved, truck involvement, time of day, police response time, and weather condition. These findings have implications for on-line applications within the context of advanced traveler information systems (ATIS).

    To ensure systems in hospitals improve to make patient care safer, learning must occur when things go wrong. Incident reporting is one of the commonest mechanisms used to learn from harm events and near misses. Only a relatively small number of incidents that occur are actually reported and different groups of staff have different rates of reporting. Nationally, junior doctors are low reporters of incidents, a finding supported by our local data. We set out to explore the culture and awareness around incident reporting among our junior doctors, and to improve the incident reporting rate within this important staff group. In order to achieve this we undertook a number of work programmes focused on junior doctors, including: assessment of their knowledge, confidence and understanding of incident reporting, education on how and why to report incidents with a focus on reporting on clinical themes during a specific time period, and evaluation of the experience of those doctors who reported incidents. Junior doctors were asked to focus on incident reporting during a one week period. Before and after this focussed week, they were invited to complete a questionnaire exploring their confidence about what an incident was and how to report. Prior to “Incident Reporting Week”, on average only two reports were submitted a month by junior doctors compared with an average of 15 per month following the education and awareness week. This project highlights the fact that using a focussed reporting period and/or specific clinical themes as an education tool can benefit a hospital by promoting awareness of incidents and by increasing incident reporting rates. This can only assist in improving hospital systems, and ultimately increase patient safety. PMID:26734264

    Atypical hemolytic uremic syndrome (aHUS) is a rare, possibly life-threatening disease characterized by platelet activation, hemolysis and thrombotic microangiopathy (TMA) leading to renal and other end-organ damage. We originally conducted two phase 2 studies (26 weeks and 1 year) evaluating eculizumab, a terminal complement inhibitor, in patients with progressing TMA (trial 1) and those with long duration of aHUS and chronic kidney disease (trial 2). The current analysis assessed outcomes after 2 years (median eculizumab exposure 100 and 114 weeks, respectively). At all scheduled time points, eculizumab inhibited terminal complement activity. In trial 1 with 17 patients, the platelet count was significantly improved from baseline, and hematologic normalization was achieved in 13 patients at week 26, and in 15 patients at both 1 and 2 years. The estimated glomerular filtration rate (eGFR) was significantly improved compared with baseline and year 1. In trial 2 with 20 patients, TMA event-free status was achieved by 16 patients at week 26, 17 patients at year 1, and 19 patients at year 2. Criteria for hematologic normalization were met by 18 patients at each time point. Improvement of 15 ml/min per 1.73 m(2) or more in eGFR was achieved by 1 patient at week 26, 3 patients at 1 year, and 8 patients at 2 years. The mean change in eGFR was not significant compared with baseline, week 26, or year 1. Eculizumab was well tolerated, with no new safety concerns or meningococcal infections. Thus, a 2-year analysis found that the earlier clinical benefits achieved by eculizumab treatment of aHUS were maintained at 2 years of follow-up.

  16. Fuzzy Logic for Incidence Geometry.

    PubMed

    Tserkovny, Alex

    The paper presents a mathematical framework for approximate geometric reasoning with extended objects in the context of Geography, in which all entities and their relationships are described by human language. These entities could be labelled by commonly used names of landmarks, water areas, and so forth. Unlike single points that are given in Cartesian coordinates, these geographic entities are extended in space and often loosely defined, but people easily perform spatial reasoning with extended geographic objects "as if they were points." Unfortunately, up to date, geographic information systems (GIS) miss the capability of geometric reasoning with extended objects. The aim of the paper is to present a mathematical apparatus for approximate geometric reasoning with extended objects that is usable in GIS. In the paper we discuss the fuzzy logic (Aliev and Tserkovny, 2011) as a reasoning system for geometry of extended objects, as well as a basis for fuzzification of the axioms of incidence geometry. The same fuzzy logic was used for fuzzification of Euclid's first postulate. Fuzzy equivalence relation "extended lines sameness" is introduced. For its approximation we also utilize a fuzzy conditional inference, which is based on proposed fuzzy "degree of indiscernibility" and "discernibility measure" of extended points.

    A 2-year randomized, controlled prospective study evaluated the clinical effectiveness of a one-step self-etch adhesive and a "gold-standard" three-step etch-and-rinse adhesive in non-carious Class-V lesions. The null hypothesis tested was that the one-step self-etch adhesive does perform clinically equally well as the three-step etch-and-rinse adhesive. A total of 161 lesions in 26 patients were restored with Clearfil AP-X (Kuraray). The restorations were bonded either with the "all-in-one" adhesive Clearfil S3 Bond (Kuraray) or with the three-step etch-and-rinse adhesive Optibond FL (Kerr). The restorations were evaluated at baseline and after 6 months, 1 and 2 years, regarding their retention, marginal adapation, marginal discoloration, caries occurrence, preservation of tooth vitality and post-operative sensivity. Retention loss, severe marginal defects and/or discoloration that needed intervention (repair or replacement) and the occurrence of caries were considered as clinical failures. The recall rate at 2 years was 93.8%. Only one Clearfil S3 Bond restoration was lost at the 2-year recall. All other restorations were clinically acceptable. The number of restorations with defect-free margins decreased severely during the 2-year study period (to 6.7% and 25.3% for Clearfil S3 Bond and Optibond FL, respectively). The Clearfil S3 Bond restorations presented significantly more small marginal defects at the enamel side than the Optibond FL restorations (Clearfil S3 Bond: 93.3%; Optibond FL: 73.3%; p = 0.000). Superficial marginal discoloration increased in both groups (to 53.3% and 36% for Clearfil S3 Bond and Optibond FL, respectively) and was also more pronounced in the Clearfil S3 Bond group (p = 0.007). After 2 years, the simplified one-step self-etch adhesive Clearfil S3 Bond and the three-step etch-and-rinse adhesive Optibond FL were clinically equally successful, even though both adhesives were characterized by progressive degradation in marginal

    Twelve cats were vaccinated at 8 and 11 weeks of age with a commercially available inactivated FeLV vaccine (Nobivac FeLV, Intervet/Schering-Plough Animal Health). Eleven cats served as age-matched, placebo-vaccinated controls. All cats were kept in isolation for 2 years after vaccination and were then challenged with virulent FeLV to evaluate vaccine efficacy and duration of immunity. Cats were monitored for 12 weeks after challenge for development of persistent viremia using a commercial FeLV p27 ELISA. Persistent viremia developed in all 11 (100%) of the control cats, whereas 10 of 12 (83%) vaccinated cats were fully protected from persistent viremia following challenge. The results demonstrate that the vaccine used in this study protects cats from persistent FeLV viremia for at least 2 years after vaccination.

    The impact of single dose mass drug administration of diethylcarbamazine (DEC), DEC with albendazole (ALB), and ivermectin (IVR) with albendazole, was examined on the human bancroftian filarial infections in village scale trials in south India, from a follow-up study after 2 years. The treatment arms administered with DEC alone and DEC+ALB demonstrated long-term benefits in reducing microfilaraemia significantly (P<0.05), while antigenaemia reduction was negligible. The arm with ALB+IVR did not show such reductions. Among the antigenaemic and microfilaraemic individuals, 87% became amicrofilaraemic in DEC+ALB arm, which were higher than that observed in the other 2 treatment arms. Among amicrofilaraemics (but Ag+), nearly 35% cleared of infection in DEC+ALB, while 26% and 6% in DEC alone and IVR+ALB arms, respectively. The drug combination DEC+ALB was observed to demonstrate a significant impact in reducing filarial infection even after 2 years post treatment.

    Young adults are at risk for weight gain in the transition to independent adulthood; 2-year college students are at greater risk and understudied relative to 4-year students. This project conducted formative research for a randomized controlled weight gain prevention trial among 2-year college students, to ensure appropriateness of content and delivery of a curriculum originally developed for 4-year college students. Data were collected from community college students, faculty, and staff from October 2009 to August 2011. Work included focus groups and key informant interviews, curriculum pilot testing, and social network and support website beta testing. Based on focus groups and interviews, program content, course delivery modes, and communication channels were adjusted to meet population interests and preferences. The course was delivered successfully in pilot testing, and the website was received well by beta testers. Formative work successfully guided program adaptations to address population needs.

    Studies have reported short-term and long-term (1-year) findings for laser skin resurfacing. Two of the most popular systems used for this procedure, the continuous-wave Sharplan 40C SilkTouch system and the pulsed Coherent 5000C UltraPulse system with a computer pattern generator, were previously compared for a range of follow-up times up to 1 year, using light microscopy and transmission electron microscopy. This study analyzed the 2-year morphological differences using scanning electron microscopy. Tissue samples were obtained from 10 patients (age range, 50 to 72 years; skin types II and III) who had undergone laser resurfacing 2 years previously. One half of the face of each patient had been treated with the continuous-wave system and the other half with the pulsed system. The samples were subjected to scanning electron microscopy. On the continuous-wave-treated side, significantly better dermal collagen organization was observed at 2 years, with plump-appearing fibers that were closely knit to form a compact structure. On the side treated with the pulsed system, the collagen fibers in the papillary dermis were more loosely arranged and appeared drier. In both the continuous-wave-treated and pulsed-treated areas, the epidermis appeared healthy and exhibited some signs of age-related deterioration, with slightly flatter plaques and somewhat more flaking keratin on the pulsed-treated side. Probably because of the greater degree of residual thermal damage associated with the continuous-wave system, at 2 years after treatment there was more prolific synthesis and better orientation of collagen fibers, which were maintained for longer times, compared with the pulsed-treated specimens.

    Abstract This study assessed the 2-year clinical outcomes of patients with diabetes mellitus (DM) after acute myocardial infarction (AMI) in a cohort of the DIAMOND (DIabetic Acute Myocardial infarctiON Disease) registry. Clinical outcomes were compared between 1088 diabetic AMI patients in the DIAMOND registry after stabilization of MI and 1088 nondiabetic AMI patients from the KORMI (Korean AMI) registry after 1 : 1 propensity score matching using traditional cardiovascular risk factors. Stabilized patients were defined as patients who did not have any clinical events within 1 month after AMI. Primary outcomes were the 2-year rate of major adverse cardiac events (MACEs), a composite of all-cause death, recurrent MI (re-MI), and target vessel revascularization (TVR). Matched comparisons revealed that diabetic patients exhibited significantly lower left ventricular ejection fraction (LVEF) and estimated glomerular filtration rate and smaller stent size. Diabetic patients exhibited significantly higher 2-year rates of MACE (8.0% vs 3.7%), all-cause death (3.9% vs 1.4%), re-MI (2.8% vs 1.2%), and TVR (3.5% vs 1.3%) than nondiabetic patients (all P < 0.01), and higher cumulative rates in Kaplan–Meier analyses of MACE, all-cause death, and TVR (all P < 0.05). A multivariate Cox regression analysis revealed that chronic kidney disease, LVEF < 35%, and long stent were independent predictors of MACE, and large stent diameter and the use of drug-eluting stents were protective factors against MACE. The 2-year MACE rate beyond 1 month after AMI was significantly higher in DM patients than non-DM patients, and this rate was associated with higher comorbidities, coronary lesions, and procedural characteristics in DM.

    Background. Despite improvements in drug-eluting stent (DES) technology, treatment strategies for long coronary artery lesions remain a controversial issue. The aim of our study was to evaluate the long-term clinical results after FFR guided PCI on long coronary lesions. Materials and methods. A total of 74 consecutive patients with significant (mean FFR 0.61 ± 0.11) coronary artery lesions ≥30 mm in length were included in the prospective study. All patients were treated with FFR guided PCI implanting newer generation Biolimus, Everolimus or Zotarolimus eluting stents. Clinical endpoints – target vessel revascularization (TVR) and major adverse cardiac events (MACE) – were recorded at 1 and 2 years. Results. 100% angiographic procedure success was achieved, the mean post procedural FFR was 0.88 ± 0.06. At 2-year follow-up, 6 (8.1%) patients had ischemia driven TVR, all within the first 12 months. There were no target vessel related acute coronary syndromes and definite stent thromboses in the study group. At 2 years, the total MACE rate was 29.7%. There was a trend towards a higher TVR rate in patients with overlapping DES vs single DES implanted (9.6 vs 4.5%, p = 0.6). On regression analysis, the total stent length had no influence on the TVR rate. Conclusions. At 2 years after stenting long coronary lesions with newer generation DES the TVR rate was 8.1%, which is acceptable in the high cardiovascular risk population with diffuse coronary artery disease. The total stent length did not affect the long-term clinical outcomes. PMID:28356786

    Psychiatric disorders such as psychosis are highly prevalent in adults with Prader-Willi syndrome (PWS). However, knowledge about the presence and progression of psychiatric disorders in children with PWS is very limited. Sixty-one children with PWS aged 7-17 years were tested using the Diagnostic Interview Schedule for Children (DISC) and Compulsive Behaviour Checklist (CBC), and 38/61 were retested after 2 years. Prevalence of psychiatric disorders and the association with age, gender, genetic subtype, and total IQ were assessed. In addition, occurrence and characteristics of compulsions were determined. Prior to the study, two boys were known with psychotic symptoms and treated with antipsychotics. At baseline, none scored positive for psychotic disorder. During the follow-up, only one boy with known psychotic symptoms required a dose adjustment of his antipsychotic medication. After 2 years, none of the children had a psychotic disorder according to the DISC. Oppositional defiant disorder (ODD) was the most common diagnosis and present in 20% of children with PWS, and this was not associated with age (β = -0.081, P = 0.546), gender (β = 0.013, P = 0.923), genetic subtype (β = -0.073, P = 0.584), or total IQ (β = -0.150, P = 0.267). The most common compulsions were hoarding and fixed hygiene sequences. In our large group of 61 children with PWS, the majority had no psychotic disorder and no progression was found during 2-year follow-up. ODD was present in 20% of children. No changes in the prevalence of psychiatric disorders were found during the 2-year follow-up study and genetic subtype was not related to psychosis, depression, or ODD.

    Vitamin deficiency after gastric bypass surgery is a known complication. The purpose of this study was to measure the incidence of vitamin deficiency after laparoscopic Roux-en-Y gastric bypass in a university hospital setting. All patients who underwent laparoscopic Roux-en-Y gastric bypass from January 2002 to December 2004 and completed a 1- and 2-year follow-up after surgery were selected. Of the total 493 patients, 318 (65%) had vitamin results at 1-year follow-up. Of the 366 eligible for the 2-year follow-up, 141 (39%) had vitamin results. Patients were further grouped based on gender, race, and Roux limb length, and incidence of vitamin deficiencies were studied. The incidence of vitamin A (retinol) deficiency was 11 per cent, vitamin C was 34.6 per cent, vitamin D25OH was 7 per cent, vitamin B1 was 18.3 per cent, vitamin B2 was 13.6 per cent, vitamin B6 was 17.6 per cent, and vitamin B12 was 3.6 per cent 12 months after surgery. There was no statistical difference in the incidence of vitamin deficiencies between 1 and 2 years. In univariate and multivariate logistic regression of 1- and 2-year follow up, black patients (vitamins A, D, and B1 for 1 year and B1 and B6 for 2 years) and women (vitamin C at 1 year) were more likely to have vitamin deficiencies. Vitamin deficiencies after laparoscopic Roux-en-Y gastric bypass are more common and involve more vitamins, even those that are water soluble, than previously appreciated. Black patients tend to have more deficiencies than other groups. The bariatric surgeon should be committed to the long-term follow-up and care of these patients. Further prospective and randomized studies are necessary to provide appropriate guidelines for supplementation.

Patients aged between 6 and 12 years and presenting at least two permanent molars in need of small class I restorations were selected. Thirty-four pairs of restorations were randomly placed by the same operator. Fifteen patients were treated under rubber dam and nineteen using cotton rolls isolation and saliva ejector. They were evaluated according to the modified USPHS criteria at baseline, 6 months, and 1 and 2 years by two independent evaluators. Results. All patients attended the two-year recall. For all measured variables, there was no significant difference between rubber dam and cotton after 2 years of restoration with Premise Flowable or Vertise Flow (p value > 0.05). The percentage of restorations scored alpha decreased significantly over time with Premise Flowable and Vertise Flow for marginal adaptation and surface texture as well as marginal discoloration while it did not vary significantly for color matching. After 2 years, Vertise Flow showed a similar behaviour to the Premise Flowable used with a self-adhesive resin system. PMID:28348594

    Hematopoietic cell transplantation (HCT) is a procedure that can significantly influence the socioeconomic wellbeing of patients, caregivers and their families. Among 30 allogeneic HCT recipients and their caregivers enrolled on a pilot study evaluating the feasibility of studying financial impact of HCT, 16 agreed to participate in the long-term phase, completed a baseline questionnaire and received phone interviews at 6, 12, 18 and 24 months post HCT. Analyses showed that by 2 years post HCT, 54% of patients who previously contributed to household earnings had not returned to work and 80% of patients/caregivers reported transplant as having moderate to great impact on household income. However, patients' levels of confidence in their abilities to meet household financial obligations increased from baseline to 2 years. A relatively large proportion of patients reported inability to pay for medical care through this time period. Case studies demonstrated that patients' individual perceptions of the financial impact of HCT varies considerably, regardless of actual income. We demonstrate the feasibility of conducting a study to evaluate the financial impact of allogeneic HCT through 2 years post transplantation. Some patients/caregivers continue to experience a significant long-term financial burden after this procedure. Our study lays the foundation for a larger evaluation of patient/caregiver financial burden associated with HCT.

    Background Immune thrombocytopenic purpura (ITP) is the most prevalent cause of thrombocytopenia in children. Despite the importance of ITP in children under 2-years old, only a few publications are available in the literature.ITP usually presents itself as isolated thrombocytopenia and mucocutaneous bleeding. Materials and Methods This study was conducted on 187 under 2-year-old children diagnosed with ITP and treated at Dr. Sheikh Hospital from 2004 to 2011.In this retrospective study, clinical symptoms, laboratory findings, history of viral infections, vaccination history, and treatment efficacy in children under 2-years old with ITP were investigated.Patients were followed for one year after being discharged from the hospital. Results The risk of the disease developing into chronic form was higher in older children (0.001). ITP in children under 3-months old was significantly associated with vaccination (p=0.007). There was no significant differences between male and female patients in regards to newly diagnosed ITP, persistent, and chronic disease status (p = 0.21). No significant difference in bleeding symptoms was observed between patients under 3-months old and 3 to 24-months old (p=0.18). Conclusion Infantile ITP respond favorably to treatment. The risk of the disease developing into chronic form is higher in 3-to-24-month-old children compared to under-three-month olds. PMID:27222699

    We evaluated 10 years of reported hazardous cargo incident information from the U.S. Air Force and Naval Safety Centers. In this first of two papers describing the hazardous cargo problems reported by the two services, we describe types of aircraft and types of hazardous cargo involved in incidents not causing aircraft mishaps. Normally, hazardous cargo must be manifested as such and no passengers are allowed on such flights. Unauthorized hazardous cargo was found on military aircraft carrying passengers. The most common problem was fuel spills or fumes. The most frequent cause of a hazardous cargo incident was improper manifest of same. Improvements are recommended for the incompatible or inconsistent hazardous cargo incident reporting systems, in order to improve prevention of hazardous cargo incidents.

  2. Semantic Theme Analysis of Pilot Incident Reports

    Pilots report accidents or incidents during take-off, on flight and landing to airline authorities and Federal aviation authority as well. The description of pilot reports for an incident contains technical terms related to Flight instruments and operations. Normal text mining approaches collect keywords from text documents and relate them among documents that are stored in database. Present approach will extract specific theme analysis of incident reports and semantically relate hierarchy of terms assigning weights of themes. Once the theme extraction has been performed for a given document, a unique key can be assigned to that document to cross linking the documents. Semantic linking will be used to categorize the documents based on specific rules that can help an end-user to analyze certain types of accidents. This presentation outlines the architecture of text mining for pilot incident reports for autonomous categorization of pilot incident reports using semantic theme analysis.

    Computer security is essential in maintaining quality in the computing environment. Computer security incidents, however, are becoming more sophisticated. The DOE Computer Incident Advisory Capability (CIAC) team was formed primarily to assist DOE sites in responding to computer security incidents. Among CIAC's other responsibilities are gathering and distributing information to DOE sites, providing training workshops, coordinating with other agencies, response teams, and vendors, creating guidelines for incident handling, and developing software tools. CIAC has already provided considerable assistance to DOE sites faced with virus infections and worm and hacker attacks, has issued over 40 information bulletins, and has developed and presented a workshop on incident handling. CIAC's experience in helping sites has produced several lessons learned, including the need to follow effective procedures to avoid virus infections in small systems and the need for sound password management and system administration in networked systems. CIAC's activity and scope will expand in the future. 4 refs.

    2006-01-01

    The incidence of hip fracture has been studied extensively, but there is still some doubt whether the age-specific incidence is increasing. The proportion of trochanteric fractures has varied and has also been said to be increasing. We studied data on 1,730 prospectively registered cases from 1998–2003 and computed age- and gender-specific incidence rates for intracapsular and trochanteric fractures. The incidence of hip fracture for women over 50 years was 1,263 and for men 452 per 100,000. The proportion of trochanteric fractures was 38% for women and 41% for men. There was no significant difference in the proportion of trochanteric fractures either between or within the genders, and the proportion did not exceed 50% in any age group. These findings confirm the high incidence of hip fracture in Norway but do not indicate any increase. The proportion of trochanteric fractures also seems to be stable. PMID:17033761

    The database of incident forms relating to anaesthesia services in an institutional risk management programme were reviewed for 2003-2005, the aim being to identify any recurring patterns. Incidents were prospectively categorised as relating to attitude/behaviour, communication breakdown, delay in service, or were related to care, cost, environment, equipment, security, administrative process, quality of service or miscellaneous. The total number of anaesthesia-related incidents reported during the period was 287, which related to 0.44% of the total number of anaesthetics administered during the time period. In all, 170 incidents were reported by the department, 96 by internal customers and 21 by external customers. Only 30% of the complaints came from the operating room. Thirty-four per cent of all incidents related to communication, behaviour and delay in service. A requirement to teach communication skills and stress handling formally in anaesthesia training programmes, and at the time of induction of staff into the department, has been identified.

    During 1975 and 1976, 2,544 canvasbacks (Aythya valisineria) from North Dakota, Wisconsin, Illinois, and Maryland were flouroscoped to determine the incidence of body shot. A significant increase from west to east was detected in the incidence of shot for immatures from the four states. The incidence of shot in immatures after the 1975-76 hunting season was 18 percent in Maryland and 20 percent in Illinois. In Wisconsin no difference in the incidence of shot could be detected between areas trapped or time periods when trapping was conducted. In Maryland a significant decrease in the incidence of body shot was detected in adults, but not immatures, between 1975 and 1976. shot was located throughout the body of canvasbacks. Frequency varied from one to nine shot per bird and averaged 2.0 for adults and 1.5 for immatures.

    Hormone replacement therapy (HRT) use declined sharply after mid-2002, when the Women's Health Initiative trial reported an association between breast cancer occurrence and HRT. Hypothesized mechanism behind this association is that HRT promotes growth of pre-existing small tumors, leading to earlier tumor detection. We evaluated the impact of the sudden decline in HRT use on age distribution of breast cancer in Geneva. We included all incident breast cancer cases recorded from 1975 to 2006 at the Geneva cancer registry. We calculated mean annual incidence rates per 100,000 for 2 year periods for three age groups and assessed temporal changes by joinpoint regression. We compared age-specific incidence curves for different periods, reflecting different prevalence rates of HRT use. After increasing constantly between 1986 and 2002 among women aged 50-69 years [annual percent change (APC): +4.4, P < 0.0001], rates declined sharply after 2003 (APC: -6.0; P = 0.0264). Age-specific breast cancer rates changed dramatically with changes in prevalence of HRT use. During low HRT prevalence, breast cancer incidence increased progressively with age, when HRT prevalence was reaching its maximum (1995-2002), higher rates were seen in 60- to 64-year-old women, with a concomitant decrease in risk among elderly. After the sudden decline in HRT use, the incidence peak diminished significantly and incidence increased again with age. Following the abrupt decline in HRT use in Geneva, breast cancer incidence rates among post-menopausal women decreased considerably with striking changes in age-specific incidence rates before, during and after the peak in HRT prevalence.

    The incidence rate of thyroid cancer has been rising rapidly in recent decades; however, its trend remains unclear. To investigate this, we analyzed the database of the Surveillance, Epidemiology and End Results (SEER) 13, 1992-2012 in the USA, particularly focusing on conventional papillary thyroid cancer (CPTC) and follicular variant of PTC (FVPTC). Of the 75,992 thyroid cancers, 61.3% were CPTC and 25.7% were FVPTC, and their incidence rates (IRs) were significantly increased from 1992 to 2012 (P all < 0.001), with CPTC being 2.4 times of FVPTC (P < 0.001) and the overall average annual percent change (AAPC) of incidence being 6.3% in the former and 5.3% in the latter. IRs were increased in all thyroid cancers, albeit most dramatically in PTC, in virtually all ethnic/demographic groups in recent two decades; however, the incidence trends varied among different thyroid cancers, particularly differentiable between CPTC and FVPTC. For example, Joinpoint analyses revealed that the APC of CPTC before 1996 was 1.5% (P > 0.05), which jumped to 6.8% (P < 0.05) after 1996, whereas the APC of FVPTC before 2000 was 6.6% (P < 0.05), which dropped to 4.8% (P < 0.05) after 2000. IRs and incidence trends of PTC were uneven among different ethnic/demographic groups, as exemplified by the lower IRs of both PTC variants in the Black females than in non-Hispanic White females but higher AAPCs of incidence in the former than in the latter. Interestingly, the data also suggest that the rise in the IRs of PTC is becoming plateaued in the most recent 2 years. These novel observations are helpful in understanding the incidence and incidence trends of thyroid cancer.

    Recent publications in both the scientific and the popular press have highlighted the risks to which patients expose themselves when entering a healthcare system. Patient safety issues are forcing us to, not only acknowledge that incidents do occur, but also actively develop the means for assessing and managing the risks of such incidents. To do this, we ideally need to know the probability of an incident's occurrence, the consequences or severity for the patient should it occur, and the basic causes of the incident. A structured approach to the description of failure modes is helpful in terms of communication, avoidance of ambiguity, and, ultimately, decision making for resource allocation. In this report, several classification schemes or taxonomies for use in risk assessment and management are discussed. In particular, a recently developed approach that reflects the activity domains through which the patient passes and that can be used as a basis for quantifying incident severity is described. The estimation of incident severity, which is based on the concept of the equivalent uniform dose, is presented in some detail. We conclude with a brief discussion on the use of a defined basic-causes table and how adding such a table to the reports of incidents can facilitate the allocation of resources.

    Cancer is the second cause of death in Argentina; nevertheless the distribution of the cancer incidence rates throughout the country is unknown. This study was conducted to describe cancer incidence patterns in Córdoba Province. Incidence data were supplied by the Government Córdoba Cancer Registry. Demographic information (age, sex, and place of residence) and diagnosis, certified by a pathologist, about all incident cases from June 2003 to May 2005 by type and 5-year age groups were obtained. Comparison of the incidence rate of cancer in various counties was performed by using standardized incidence rates (SIR) per 100,000 inhabitants using the world standard population. Estimated SIRs were used to build up incidence maps. Two indicators were created: sex ratio and site-specific ratio. Mixed Poisson models were fitted. Taken as a whole for all counties, SIR was 121.42 and 141.57 for men and women, respectively. The most common sites in men were prostate (13.62), lung (10.12), colon (7.53), and bladder (7.03); in women were breast (22.51) and colon (3.31). The highest and lowest rates were in urban and rural areas, respectively. Cancer registry has a pivotal role in cancer control. Such information is the primary resource of information not only for epidemiological research on cancer determinants but also for planning and evaluating health services for the policies of prevention, diagnosis and treatment of the disease.

    OBJECTIVE Although multiple reports have documented significant benefit from surgical treatment of adult spinal deformity (ASD), these procedures can have high complication rates. Previously reported complications rates associated with ASD surgery are limited by retrospective design, single-surgeon or single-center cohorts, lack of rigorous data on complications, and/or limited follow-up. Accurate definition of complications associated with ASD surgery is important and may serve as a resource for patient counseling and efforts to improve the safety of patient care. The authors conducted a study to prospectively assess the rates of complications associated with ASD surgery with a minimum 2-year follow-up based on a multicenter study design that incorporated standardized data-collection forms, on-site study coordinators, and regular auditing of data to help ensure complete and accurate reporting of complications. In addition, they report age stratification of complication rates and provide a general assessment of factors that may be associated with the occurrence of complications. METHODS As part of a prospective, multicenter ASD database, standardized forms were used to collect data on surgery-related complications. On-site coordinators and central auditing helped ensure complete capture of complication data. Inclusion criteria were age older than 18 years, ASD, and plan for operative treatment. Complications were classified as perioperative (within 6 weeks of surgery) or delayed (between 6 weeks after surgery and time of last follow-up), and as minor or major. The primary focus for analyses was on patients who reached a minimum follow-up of 2 years. RESULTS Of 346 patients who met the inclusion criteria, 291 (84%) had a minimum 2-year follow-up (mean 2.1 years); their mean age was 56.2 years. The vast majority (99%) had treatment including a posterior procedure, 25% had an anterior procedure, and 19% had a 3-column osteotomy. At least 1 revision was required in 82

    "Optimal lifestyle," comprising abstinence from smoking, adequate physical activity, eating 5 servings of fruits and vegetables each day, and consuming limited or no alcohol, is associated with low risk of chronic disease when unselected populations are observed for long periods of time. It is unclear whether these same associations are present when observation is limited to employed individuals followed for a brief period of time. The purpose of this investigation was to study the association between adherence to optimal lifestyle and the incidence of chronic conditions among employees over a 2-year period. Logistic regression was used to assess the association between employees' (N  = 6848) adherence to optimal lifestyle and the incidence of diabetes, heart disease, cancer, hypertension, high cholesterol, and back pain during a 2-year period. All data were self-reported. Adherence to any 3 components of the optimal lifestyle was associated with a significantly lower near-term incidence of diabetes (odds ratio [OR] =  0.56; 95% confidence interval [CI] = 0.31-0.97) and back pain (OR = 0.69; 95% CI = 0.53-0.92). Adherence to all 4 optimal lifestyle components was significantly associated with lower near-term incidence of back pain (OR = 0.44; 95% CI = 0.26-0.76). Physical activity was associated with significantly lower near-term incidence risk of heart disease (OR = 0.60; 95% CI = 0.38-0.95), high cholesterol (OR = 0.80; 95% CI = 0.66-0.99), and diabetes (OR = 0.51; 95% CI = 0.30-0.86). Adherence to optimal lifestyle, in particular adequate physical activity, is associated with lower near-term risk of developing several chronic conditions. Employers and payers should consider this fact when formulating policy or allocating resources for health care and health promotion.

    Recent work has shown the presence of anomalous dissolved organic matter (DOM), with high optical yields, in deep waters 15 months after the Deepwater Horizon (DWH) oil spill in the Gulf of Mexico (GOM). Here, we continue to use the fluorescence excitation-emission matrix (EEM) technique coupled with parallel factor analysis (PARAFAC) modeling, measurements of bulk organic carbon, dissolved inorganic carbon (DIC), oil indices, and other optical properties to examine the chemical evolution and transformation of oil components derived from the DWH in the water column of the GOM. Seawater samples were collected from the GOM during July 2012, 2 years after the oil spill. This study shows that, while dissolved organic carbon (DOC) values have decreased since just after the DWH spill, they remain higher at some stations than typical deep-water values for the GOM. Moreover, we continue to observe fluorescent DOM components in deep waters, similar to those of degraded oil observed in lab and field experiments, which suggest that oil-related fluorescence signatures, as part of the DOM pool, have persisted for 2 years in the deep waters. This supports the notion that some oil-derived chromophoric dissolved organic matter (CDOM) components could still be identified in deep waters after 2 years of degradation, which is further supported by the lower DIC and partial pressure of carbon dioxide (pCO2) associated with greater amounts of these oil-derived components in deep waters, assuming microbial activity on DOM in the current water masses is only the controlling factor of DIC and pCO2 concentrations.

    Conclusion This study indicates that IL-10 promoter polymorphism variants, smoking, and alcohol consumption increase the risk of recurrence and canceration in vocal leukoplakia. Objective This prospective, clinical trial was performed to evaluate the association of interleukin (IL)-10 promoter polymorphism variants and canceration and recurrence rates in vocal leukoplakia (a pre-cancerous laryngeal carcinoma lesion) over a 2-year period. Participants and method Sixty-one post-operative patients with vocal leukoplakia were enrolled in this prospective, observational study and genotyped for the IL-10 promoter gene (IL-10-1082 A/G, -819 T/C and -592 A/C) using pyrosequencing, and responded to a 2-year follow-up survey. Recurrence and canceration rates were used to evaluate the association between the genotype variants and the clinical outcome. Results There was an increased canceration rate in the variant genotype group compared to that in the normal genotype group in the 2-year follow-up period (18.4% vs 0%, p-value = 0.038). Compared with the non-smoker group, the smoker group had a higher recurrence rate of vocal leukoplakia (29.3% vs 5%, p-value =0.044). Likewise, the recurrence rate in the alcohol consumption group was also higher (30.6% vs 8%, p-value =0.034). The percentage of cancerization in the alcohol consumption group was significantly higher than that in the non-alcohol consumption group (19.4% vs 0%, p-value =0.035).

    Because of the shortage of agalsidase-β supply between 2009 and 2012, patients with Fabry disease either were treated with reduced doses or were switched to agalsidase-α. In this observational study, we assessed end organ damage and clinical symptoms with special focus on renal outcome after 2 years of dose-reduction and/or switch to agalsidase-α. A total of 89 adult patients with Fabry disease who had received agalsidase-β (1.0 mg/kg body wt) for >1 year were nonrandomly assigned to continue this treatment regimen (regular-dose group, n=24), to receive a reduced dose of 0.3-0.5 mg/kg and a subsequent switch to 0.2 mg/kg agalsidase-α (dose-reduction-switch group, n=28), or to directly switch to 0.2 mg/kg agalsidase-α (switch group, n=37) and were followed-up for 2 years. We assessed clinical events (death, myocardial infarction, severe arrhythmia, stroke, progression to ESRD), changes in cardiac and renal function, Fabry-related symptoms (pain, hypohidrosis, diarrhea), and disease severity scores. Determination of renal function by creatinine and cystatin C-based eGFR revealed decreasing eGFRs in the dose-reduction-switch group and the switch group. The Mainz Severity Score Index increased significantly in these two groups (P=0.02 and P<0.001, respectively), and higher frequencies of gastrointestinal pain occurred during follow-up. In conclusion, after 2 years of observation, all groups showed a stable clinical disease course with respect to serious clinical events. However, patients under agalsidase-β dose-reduction and switch or a direct switch to agalsidase-α showed a decline of renal function independent of the eGFR formula used.

    Purpose: This single-center randomized trial was designed to investigate whether intensity-modulated radiotherapy (IMRT) reduces late toxicity in patients with early-stage breast cancer. Methods and Materials: The standard tangential plans of 1,145 nonselected patients were analyzed. The patients with inhomogeneous plans were randomized to a simple method of forward-planned IMRT or standard radiotherapy (RT). The primary endpoint was serial photographic assessment of breast shrinkage. Results: At 2 years, no significant difference was found in the development of any photographically assessed breast shrinkage between the patients randomized to the interventional or control group (odds ratio, 1.51; 95% confidence interval, 0.83-1.58; p = .41). The patients in the control group were more likely to develop telangiectasia than those in the IMRT group (odds ratio, 1.68; 95% confidence interval 1.13-2.40; p = .009). Poor baseline surgical cosmesis resulted in poor overall cosmesis at 2 years after RT. In patients who had good surgical cosmesis, those randomized to IMRT were less likely to deteriorate to a moderate or poor overall cosmesis than those in the control group (odds ratio, 0.63; 95% confidence interval, 0.39-1.03, p = .061). Conclusions: IMRT can lead to a significant reduction in telangiectasia at comparatively early follow-up of only 2 years after RT completion. An important component of breast induration and shrinkage will actually result from the surgery and not from the RT. Surgical cosmesis is an important determinant of overall cosmesis and could partially mask the longer term benefits of IMRT at this early stage.

    AIM The aim of the study was to assess the influence of national and international warnings on the prescription rates of cough and cold medicines (CCMs) in the youngest children (<2 years) in the Netherlands and Italy. METHODS Analysis of outpatient electronic medical records of children <2 years in Italy and the Netherlands was carried out. Age and country specific prescription prevalence rates were calculated for the period 2005–08. Comparisons of prescription rates in 2005 (pre) and 2008 (post) warnings were done by means of a chi-square test. RESULTS The cohort consisted of 99 176 children <2 years of age. After international warnings, overall prescription rates for CCMs decreased slightly from 83 to 77/1000 person years (P = 0.05) in Italy and increased in the Netherlands from 74 to 92/1000 children per year. Despite the international warnings, prescription rates for nasal sympathomimetics and opium alkaloids increased in the Netherlands (P < 0.01). In Italy a significant decrease in the prescription rates of opium alkaloids and other cough suppressants (P < 0.01) was observed, and also a significant reduction in use of combinations of nasal sympathomimetics. CONCLUSION Despite the international safety warnings and negative benefit-risk profiles, prescription rates of cough and cold medicines remain substantial and were hardly affected by the warnings, especially in the Netherlands where no warning was issued. The hazards of use of these medicines in young children should be explicitly stipulated by the European Medicines Agency and all national agencies, in order to increase awareness amongst physicians and caretakers and reduce heterogeneity across the EU.

    To compare the levels of agreement and the survival rates of sealant retention for different sealing materials over a 2-year period assessed using the visual clinical examination and replica methods, sealant retention data were obtained by visual clinical examination and from replicas of the same sealed tooth at baseline and at 0.5-, 1- and 2-year evaluation points in 407 children and were compared for agreement using kappa coefficients. Survival curves of retained sealants on occlusal surfaces were created using modified categorisation (fully retained sealants and those having all pits and fissures partly covered with the sealant material versus completely lost sealants that included pit and fissure systems that had ≥1 pit re-exposed) according to the Kaplan–Meier method. The kappa coefficient for the agreement between both assessment methods over the three evaluation time points combined was 0.38 (95% confidence interval (CI): 0.35–0.41). More sealant retention was observed from replicas than through visual clinical examination. Cumulative survival curves at the three evaluation times were not statistically significantly higher when assessed from replicas (P=0.47). Using the replica method, more retained sealant material was observed than through visual clinical examination during the 2-year period. This finding did not result in a difference in the survival rates of sealants assessed by the two assessment methods. When replicas cast in die stone are used for assessing sealant retention, the level of reliability of the data is higher than that of data obtained through the commonly used visual clinical examination, particularly if such assessments are conducted over time.

    Aim: To assess clinical, visual, computerised corneal topographic, and subjective satisfaction with visual acuity, in a cohort of subjects 2 years after phacoemulsification surgery in a public hospital in New Zealand. Methods: Prospective study of a representative sample of 97 subjects (20%) randomly selected from 480 subjects in the original Auckland Cataract Study (ACS) cohort. The clinical assessment protocol was identical to the ACS and included an extensive questionnaire to enable direct comparisons to be made between the two groups. Results: The study population was predominantly female (66%) with a mean age of 76.3 (SD 9.9) years. New systemic and ocular disease affected 18.4% and 10.3% of subjects respectively, and 10.3% required referral to either a general practitioner (2.1%) or ophthalmologist (8.2%). Mean best spectacle corrected visual acuity (BSCVA) was 0.2 (0.2) logMAR units (6/9 Snellen equivalent), with mean spherical equivalent −0.37 (1.01) dioptres (D) and astigmatism −1.07 (0.70) D 2 years postoperatively, compared to mean BSCVA 0.1 (0.2) logMAR units (6/7.5 Snellen equivalent), spherical equivalent −0.59 (1.07) D, and astigmatism −1.14 (0.77) D 4 weeks after surgery. 94.9% of subjects retained a BSCVA of 6/12 or better, irrespective of pre-existing ocular disease. The overall posterior capsule opacification (PCO) rate was 20.4% and this was visually insignificant in all but 3.1% of eyes that had already undergone Nd:YAG posterior capsulotomy. Orbscan II elevation technology demonstrated corneal stability 2 years after uncomplicated phacoemulsification. Although corneal astigmatism was eliminated in approximately half of the subjects 1 month postoperatively, astigmatism showed a tendency to regress towards the preoperative level with local corneal thickening at the site of incision 2 years after cataract surgery. Of fellow eyes, 61.2% had undergone cataract surgery. Overall, 75.3% of subjects were moderately to very satisfied with their

    Traffic incidents are key contributors to non-recurrent congestion, potentially generating significant delay. Factors that influence the duration of incidents are important to understand so that effective mitigation strategies can be implemented. To identify and quantify the effects of influential factors, a methodology for studying total incident duration based on historical data from an 'integrated database' is proposed. Incident duration models are developed using a selected freeway segment in the Southeast Queensland, Australia network. The models include incident detection and recovery time as components of incident duration. A hazard-based duration modelling approach is applied to model incident duration as a function of a variety of factors that influence traffic incident duration. Parametric accelerated failure time survival models are developed to capture heterogeneity as a function of explanatory variables, with both fixed and random parameters specifications. The analysis reveals that factors affecting incident duration include incident characteristics (severity, type, injury, medical requirements, etc.), infrastructure characteristics (roadway shoulder availability), time of day, and traffic characteristics. The results indicate that event type durations are uniquely different, thus requiring different responses to effectively clear them. Furthermore, the results highlight the presence of unobserved incident duration heterogeneity as captured by the random parameter models, suggesting that additional factors need to be considered in future modelling efforts.

    This study explored how fourth-year nursing students (n = 10) from one urban baccalaureate nursing program perceived incidents potentially harmful to patients, as well as incident reporting. Individual interviews were conducted. Five scenarios were presented in the interviews, with each scenario portraying a situation that varied in terms of the severity of potential for patient harm and the clinical team members involved. Participants' responses were analyzed using a descriptive thematic approach. Of the 50 events (10 participants × 5 scenarios), participants identified 37 events as incidents. Three themes emerged regarding how participants identified an incident: scope of practice, professional roles, and harm to the patient. Regarding 48 of the 50 events, participants said they would report these incidents either informally or formally. Findings from this study suggest a need for nursing education regarding what constitutes an incident, as well as how and when to report incidents.

    Although there is a worldwide increase in maxillofacial trauma incidence; the pattern and etiology of these injuries varies from one country to another depending on socioeconomic, cultural, and environmental factors. This study aims to realize the epidemiological characteristics of maxillofacial fractures in our department. A retrospective cross-sectional study of all facial trauma patients admitted to our department during 2009 to 2012. Patients' data including gender, age, etiology of trauma, the pattern and demographic distribution of fractures of maxillofacial skeleton, and associated injuries were analyzed and compared with previously published data. The chi-square test was used with a p value of less than 0.05, which was considered statistically significant. There is a significant increase in maxillofacial fractures incidence in the past 2 years than former ones. There is a male predominance with highest incidence in the age group of 20 to 40 years. Road traffic accident is the most common etiological factor followed by violence. There is increase in mandibular fracture incidence compared with midface. The significant increased incidence of maxillofacial fracture due to motor car accidents and assaults in the past 2 years reflects a behavioral change within the community. PMID:25136412

    All radiation devices in use nowadays are subject to cause serious incidents and accidents, with potential risks in exposed population groups. These risks may have immediate or long term health implications. The detection of radioactive incidents is a procedure that should be systematized in economically developed societies. International organizations may provide support to other states in the event of a radioactive incident. Prevention, mitigation and treatment of the radiation effects are done by anticipating the moment of exposure and by establishing new efforts for investigation of radioprotective products. In this article we will analyze the causes of radiological incidents, the means to detect them, and the current preventive and therapeutic procedures available, with special emphasis on new biodosimetry methods for triage and investigational radioprotective drugs. Finally, we will explore the most efficient measures, for future prevention. PMID:24376973

    As the penetration of software into safety-critical systems progresses, accidents and incidents involving software will inevitably become more frequent. Identifying lessons from these occurrences and applying them to existing and future systems is essential if recurrences are to be prevented. Unfortunately, investigative agencies do not have the resources to fully investigate every incident under their jurisdictions and domains of expertise and thus must prioritize certain occurrences when allocating investigative resources. In the aviation community, most investigative agencies prioritize occurrences based on the severity of their associated losses, allocating more resources to accidents resulting in injury to passengers or extensive aircraft damage. We argue that this scheme is inappropriate because it undervalues incidents whose recurrence could have a high potential for loss while overvaluing fairly straightforward accidents involving accepted risks. We then suggest a new strategy for prioritizing occurrences based on the risk arising from incident recurrence.

    Objectives. We examined self-reported physical health during the first 2 years following the 2004 tsunami in Thailand. Methods. We assessed physical health with the revised Short Form Health Survey. We evaluated 6 types of tsunami exposure: personal injury, personal loss of home, personal loss of business, loss of family member, family member’s injury, and family’s loss of business. We examined the relationship between tsunami exposure and physical health with multivariate linear regression. Results. One year post-tsunami, we interviewed 1931 participants (97.2% response rate), and followed up with 1855 participants 2 years after the tsunami (96.1% follow-up rate). Participants with personal injury or loss of business reported poorer physical health than those unaffected (P < .001), and greater health impacts were found for women and older individuals. Conclusions. Exposure to the tsunami disaster adversely affected physical health, and its impact may last for longer than 1 year, which is the typical time when most public and private relief programs withdraw.

    AIM To determine outcomes using the Femoro-Patella Vialla (FPV) arthroplasty and if there is an ideal patient for this implant. METHODS A total of 41 FPV patellofemoral joint replacements were performed in 31 patients (22 females, 9 males, mean age 65 years). Mean follow-up was 3.2 years (minimum 2 years). Radiographs were reviewed preoperatively and postoperatively. We assessed whether gender, age, previous surgery, patella atla or trochlear dysplasia influenced patient satisfaction or patient functional outcome. RESULTS The median Oxford Knee Score was 40 and the median Melbourne Patellofemoral Score was 21 postoperatively. Seventy-six percent of patients were satisfied, 10% unsure and 14% dissatisfied postoperatively. There was no radiological progression of tibiofemoral joint arthritis, using the Ahlback grading, in any patient. One patient, who was diagnosed with rheumatoid arthritis postoperatively, underwent revision to total knee replacement. There were no intraoperative lateral releases and no implant failures. Gender, age, the presence of trochlear dysplasia, patella alta or bilateral surgery did not influence patient outcome. Previous surgery did not correlate with outcome. CONCLUSION In contrast to the current literature, the FPV shows promising early results. However, we cannot identify a subgroup of patients with superior outcomes. PMID:27622149

    Background. We present a rare case of bilateral moyamoya disease presenting as multiple strokes and neurological deficits, treated with the neurosurgical procedure, encephaloduroarteriosynangiosis (EDAS), in a 2-year-old male Pakistani minor. A positive outcome was achieved and the patient recovered fully. Case Summary. Our patient presented with a history of seizures and multiple episodes of hemiparesis (on and off weakness) at the age of 2 years. He had a delayed speech development and could not speak more than a few words. He had a slight slurring of speech too. He was diagnosed with bilateral moyamoya disease on Computed Tomography Angiography (CTA). Bilateral EDAS was done in the same year, after which his symptoms improved and patient had moderate functional recovery. Conclusion. A rare disease, moyamoya has been left unexplored in Pakistan; physicians and surgeons when dealing with cases in the pediatric population presenting with symptoms of stroke, signs of generalized weakness, and seizures should consider moyamoya disease as a possibility. Furthermore, this case demonstrates the effectiveness of EDAS procedure for the treatment of moyamoya disease. PMID:28101388

    AIMS—To determine if there is any association between the findings of visual assessment performed at the age of 5 months and neurodevelopmental outcome at the age of 2 years in children who have sustained hypoxic-ischaemic insults.
METHODS—Twenty nine term infants with hypoxic-ischaemic encephalopathy and/or brain lesions on neonatal magnetic resonance imaging (MRI) were prospectively evaluated. At 5 months of age all the infants had their visual function assessed using the Atkinson Battery of Child Development for Examining Functional Vision, which includes the assessments of optokinetic nystagmus (OKN), acuity, visual fields, fixation shift and phase and orientation reversal visual evoked potentials. At 2 years of age the children had a structured neurological evaluation and a Griffiths developmental assessment.
RESULTS—There was good correlation between the extent of the early detected visual impairment and both neuromotor and global development. Children with more than three out of five abnormal visual tests at 5 months of age tended to have abnormal neurological examination results and abnormal developmental quotients. Children with three or fewer abnormalities tended to have developmental quotients in the normal range; the level of their performance, however, was still related to the number of visual tests passed.
CONCLUSIONS—Individual visual tests can provide important prognostic information. While abnormal OKN and acuity were always associated with abnormal outcome, normal results on visual evoked potentials and fixation shift tended to be associated with normal outcome.

    To evaluate the 2-year post-operative outcomes of pediatric patients with chronic rhinosinusitis (CRS) treated with balloon catheter sinuplasty (BCS) and ethmoidectomy compared to functional endoscopic sinus surgery (FESS). Two-group, retrospective cohort study of 28 children with CRS was performed. Of these 28 participants, 15 were treated with traditional FESS (53.6 %) and 13 (46.4 %) underwent traditional ethmoidectomy with balloon sinuplasty. Pre-operative and 2-year postoperative total symptom scores and medications were compared. To examine the potential long-term differences in surgical outcomes and surgical procedure on symptom outcome, one-tailed Chi square analyses were employed. The mean age of the children examined was 9.3 (SD = SD = 4.1; range 3-18) and 61.9 % were male. Pre-operative symptomatology, medication and Lund Mackay scores were evaluated for both groups and no significant differences were identified. Overall, 73.3 % of children that underwent traditional FESS and 76.9 % of those who had BCS with ethmoidectomy reported significant long-term improvement in at least one of their pre-operative sinus complaints. Our data suggests that both BCS with ethmoidectomy and traditional FESS are effective treatment options for uncomplicated CRS and result in long-term alleviation of core sinus complaints, as well as decreased sinus related medication use. Larger prospective studies are needed to further evaluate these procedures.

    Background: Growth is one of the most important indices in child health. The best and most effective way to investigate child health is measuring the physical growth indices such as weight, height and head circumference. Among these measures, weight growth is the simplest and the most effective way to determine child growth status. Weight trend at a given age is the result of cumulative growth experience, whereas growth velocity represents what is happening at the time. Methods: This longitudinal study was conducted among 606 children repeatedly measured from birth until 2 years of age. We used linear mixed model to analyze repeated measures and to determine factors affecting the growth trajectory. LOWESS smooth curve was used to draw velocity curves. Results: Gender, child rank, birth status and feeding mode had a significant effect on weight trajectory. Boys had higher weight during the study. Infants with exclusive breast feeding had higher weight than other infants. Boys had higher growth velocity up to age 6 month. Breast fed infants had higher growth velocity up to 6 month, but thereafter the velocity was higher in other infants. Conclusions: Many of the studies have investigated child growth, but most of them used cross-sectional design. In this study, we used longitudinal method to determine effective factors on weight trend in children from birth until 2-year-old. The effects of perinatal factors on further growth should be considered for prevention of growth disorders and their late complications. PMID:24829720

    Background High-dose use of benzodiazepines (BZPs) reportedly causes adverse effects on cognitive function and quality of life in patients with schizophrenia. However, effects of BZPs on the clinical course of schizophrenia have not been clarified. This study was set out to investigate the association between BZPs and rehospitalization of patients with schizophrenia. Methods In this retrospective study, patients with schizophrenia who were discharged from Tokyo Medical University Hospital between January 2009 and February 2012 were eligible as subjects. One hundred and eight patients who continued treatment for >2 years after hospital discharge were included in this study. Clinical characteristics, doses of prescribed medication such as BZPs and antipsychotics, and Global Assessment of Functioning scores at discharge were investigated. The primary outcome was rehospitalization of patients for any reason. Results In a total of 108 subjects with schizophrenia, 44 subjects (40.7%) experienced rehospitalization during the 2-year study period. A multivariate analysis by the Cox proportional hazards model revealed that low educational history (hazard ratio =2.43, P=0.032), younger onset age of schizophrenia (hazard ratio =2.10, P=0.021), and higher diazepam-equivalent dose (hazard ratio =6.53, P=0.011) were significantly associated with the time to rehospitalization after hospital discharge. Conclusion The results of this study suggest that high-dose use of BZPs at discharge in patients with schizophrenia might be associated with a shorter time to rehospitalization. PMID:28008260

    We numerically analyze at near-grazing incidence various configurations containing elliptical, toroidal, and the recently proposed common-axis rotationally symmetric anamorphic (CARSA) elements to determine the type and importance of aberrations inherent in each. CARS pairs of elliptical mirrors are shown to have negligible focusing errors for typical synchrotron source dimensions, and therefore comprise useful building blocks from which to construct grazing-incidence optical systems. To minimize aberrations, cylindrical, spherical, or toroidal elements should be avoided.

    The Mars Pathfinder mission has three different solar arrays each of which sees changes in incidence angle during normal operation. When solar array angle of incidence effects was researched little published data was found. The small amount of-published data created a need to obtain and evaluate such data. The donation of the needed data, which was taken in the fall of 1994, was a major factor in the preparation of this paper.

    ASHMET computer program estimates amount of solar insolation incident on surfaces of several types of solar collectors, including fixed-position flat-plate, monthly-tilt-adjusted flat-plat, beam-tracting, and fixed-azimuthtracker. Basic methodology employed in ASHMET is to use ASHRAE relationships to obtain clear-day total daily insolation incident on collector surface of representative day of each month of year. ASHMET is interactive program and prompts user for all required data.

    Abstract Population-based studies of the incidence of tuberculosis in cancer patients according to the type of cancer are limited. We investigated the cancer-specific incidence of tuberculosis in a nationwide population-based cohort in a country with an intermediate burden of tuberculosis. We used mandatory National Health Insurance claims data to construct a cancer cohort of adults (aged 20–99 years) with newly diagnosed malignancies other than lung cancer, from January 2008 to December 2012. Patients who developed tuberculosis in this period were identified in the cancer cohort and the general population. Standardized incidence ratios (SIRs) of tuberculosis in the cancer cohort according to type of cancer and time after cancer diagnosis were calculated by comparing the observed incidence rates with those inferred from the age- and gender-specific incidence rates in the general population. A total of 855,382 cancer patients and 1589,876 person-years (py) were observed. A total of 5745 patients developed tuberculosis; the mean incidence rate was 361.3 per 100,000 py, and the SIR was 2.22 (95% confidence interval [CI], 2.17–2.27). The incidence rate was highest for hematologic malignancy and lowest for thyroid cancer. It was also highest as 650.1 per 100,000 py, with SIR of 3.70 (CI, 3.57–3.83) for the first 6 months after diagnosis of malignancy and then declined. However, it still remained higher than that of the general population after 24 months (SIR = 1.43, CI, 1.36–1.51). The incidence of tuberculosis increases after diagnosis in patients with malignancies. The risk of tuberculosis differs according to the type of cancer and remains elevated even 24 months after cancer diagnosis. Tuberculosis should be considered an important comorbidity in patients with malignancies. PMID:27661041

    2013-01-01

    Background Reservoirs created by damming rivers are often believed to increase malaria incidence risk and/or stretch the period of malaria transmission. In this paper, we report the effects of a mega hydropower dam on P. falciparum malaria incidence in Ethiopia. Methods A longitudinal cohort study was conducted over a period of 2 years to determine Plasmodium falciparum malaria incidence among children less than 10 years of age living near a mega hydropower dam in Ethiopia. A total of 2080 children from 16 villages located at different distances from a hydropower dam were followed up from 2008 to 2010 using active detection of cases based on weekly house to house visits. Of this cohort of children, 951 (48.09%) were females and 1059 (51.91%) were males, with a median age of 5 years. Malaria vectors were simultaneously surveyed in all the 16 study villages. Frailty models were used to explore associations between time-to-malaria and potential risk factors, whereas, mixed-effects Poisson regression models were used to assess the effect of different covariates on anopheline abundance. Results Overall, 548 (26.86%) children experienced at least one clinical malaria episode during the follow up period with mean incidence rate of 14.26 cases/1000 child-months at risk (95% CI: 12.16 - 16.36). P. falciparum malaria incidence showed no statistically significant association with distance from the dam reservoir (p = 0.32). However, P. falciparum incidence varied significantly between seasons (p < 0.01). The malaria vector, Anopheles arabiensis, was however more abundant in villages nearer to the dam reservoir. Conclusions P. falciparum malaria incidence dynamics were more influenced by seasonal drivers than by the dam reservoir itself. The findings could have implications in timing optimal malaria control interventions and in developing an early warning system in Ethiopia. PMID:23566411

    The aim of this article is to describe the incidence and types of safety reports logged in the radiology safety incident reporting system in our emergency radiology section over an 8-year period. Electronic incident reporting system of our institute was searched for the variables in emergency radiology. All reports from April 2006 to June 2014 were included and deindentified. The following event classifications were investigated in radiography, CT, and MRI modalities: diagnostic test orders, ID/documentation/consent, safety/security/conduct, service coordination, surgery/procedure, line/tube, fall, medication/IV safety, employee general incident, environment/equipment, adverse drug reaction, skin/tissue, and diagnosis/treatment. A total of 881,194 emergency radiology examinations were performed during the study period, 1717 (1717/881,194 = 0.19 %) of which resulted in safety reports. Reports were classified into 14 different categories, the most frequent of which were "diagnostic test orders" (481/1717 = 28 % total incident reports), "medication/IV safety" (302/1717 = 18 % total incident reports), and "service coordination" (204/1717 = 12 % total incident reports). X-ray had the highest report rate (873/1717 = 50 % total incident reports), followed by CT (604/1717 = 35 % total incident reports) and MRI (240/1717 = 14 % total incident reports). Forty-six percent of safety incidents (789/1717) caused no harm and did not reach the patient, 36 % (617/1717) caused no harm but reached the patient, 18 % (308/1717) caused temporary or minor harm/ damage, and less than 1 % caused permanent or major harm/ damage or death. Our study shows an overall safety incident report rate of 0.19 % in emergency radiology including radiography, CT, and MRI modalities. The most common safety incidents were diagnostic test orders, medication/IV safety, and service coordination.

    Background The purpose of this study was to identify incidence and survival patterns in conformational neurodegenerative disorders (CNDDs). Methods We identified 2563 reports on the incidence of eight conditions representing sporadic, acquired and genetic, protein-associated, i.e., conformational, NDD groups and age-related macular degeneration (AMD). We selected 245 papers for full-text examination and application of quality criteria. Additionally, data-collection was completed with detailed information from British, Swedish, and Spanish registries on Creutzfeldt-Jakob disease (CJD) forms, amyotrophic lateral sclerosis (ALS), and sporadic rapidly progressing neurodegenerative dementia (sRPNDd). For each condition, age-specific incidence curves, age-adjusted figures, and reported or calculated median survival were plotted and examined. Findings Based on 51 valid reported and seven new incidence data sets, nine out of eleven conditions shared specific features. Age-adjusted incidence per million person-years increased from ≤1.5 for sRPNDd, different CJD forms and Huntington's disease (HD), to 1589 and 2589 for AMD and Alzheimer's disease (AD) respectively. Age-specific profiles varied from (a) symmetrical, inverted V-shaped curves for low incidences to (b) those increasing with age for late-life sporadic CNDDs and for sRPNDd, with (c) a suggested, intermediate, non-symmetrical inverted V-shape for fronto-temporal dementia and Parkinson's disease. Frequently, peak age-specific incidences from 20–24 to ≥90 years increased with age at onset and survival. Distinct patterns were seen: for HD, with a low incidence, levelling off at middle age, and long median survival, 20 years; and for sRPNDd which displayed the lowest incidence, increasing with age, and a short median disease duration. Interpretation These results call for a unified population view of NDDs, with an age-at-onset-related pattern for acquired and sporadic CNDDs. The pattern linking age at onset to

    To evaluate influence of laparoscopic gastric banding (LGB) on quality of life (QOL) in patients with morbid obesity. Laparoscopic adjustable gastric banding is a popular bariatric operation in Europe. The objectives of surgical therapy in patients with morbid obesity are reduction of body weight, and a positive influence on the obesity-related comorbidity as well the concomitant psychologic and social restrictions of these patients. In a prospective clinical trial, development of the individual patient QOL was analyzed, after LGB in patients with morbid obesity. From October 1999 to January 2001, 152 patients [119 women, 33 men, mean age 38.4 y (range 24 to 62), mean body mass index 44.3 (range 38 to 63)] underwent evaluation for LGB according the following protocol: history of obesity; concise counseling of patients and relative on nonsurgical treatment alternatives, risk of surgery, psychologic testing, questionnaire for eating habits, necessity of lifestyle change after surgery; medical evaluation including endocrinologic and nutritionist work-up, upper GI endoscopy, evaluation of QOL using the Gastro Intestinal Quality of Life Index (GIQLI). Decision for surgery was a multidisciplinary consensus. This group was follow-up at least 2 years, focusing on weight loss and QOL. Mean operative time was 82 minutes; mean hospital stay was 2.3 days and the mean follow-up period was 34 months. The BMI dropped from 44.3 to 29.6 kg/m and all comorbid conditions improved markedly: diabetes melitus resolved in 71% of the patients, hypertension in 33%, and sleep apnea in 90%. However, 26 patients (17%) had late complications requiring reoperation. Preoperative global GIQLI score was 95 (range 56 to 140), significant different of the healthy volunteers score (120) (70 to 140) P < 0.001. Correlated with weight loss (percentage loss of overweight and BMI), the global score of the group increased to 100 at 3 months, 104 at 6, 111 at 1 year to reach 119 at 2 years which is no

    Abstract The objective of the present study was to evaluate the 2-year effectiveness of modified Shenzhuo formula in the treatment of overt proteinuria diabetic kidney disease (DKD). Patients diagnosed with type 2 DKD in the clinical research database of Prof Xiaolin Tong (>20,000 data points) with >1-year follow-up were screened for this study. Patients’ demographic data, chief complaint, present illness, past history, allergic history, personal history, family history, test results, tongue images, pulse information, and prescription information at 1, 1.5, and 2 years of follow-up were analyzed. EpiData3.1 was used to establish the electronic database of this research and SPSS v20.0 (SPSS Inc, Chicago, IL) was used for performing statistical analyses. The patients’ common main symptoms of overt proteinuria DKD were weak breath and fatigue, numbness of limbs, insomnia, blurred vision, nocturia, edema, low backache, constipation, itchy skin ulcer, and chills. The average 24-hour urinary protein of patients treated with modified Shenzhuo formula was statistically significantly lower than baseline values at 1, 1.5, and 2 years (0.66 g, 95% confidence interval [CI] [−0.95, −0.41]; 1.00 g, 95% CI [−1.67, 0.38]; 1.11 g, 95% CI [−1.79, −0.57]). There are no statistically significant differences between the glomerular filtration rate at the baseline and that after modified Shenzhuo formula intervention. Statistically significant reductions in serum triglyceride and glycosylated hemoglobin values and systolic blood pressure also were recorded. Other indexes, including serum creatinine, blood urea nitrogen, diastolic blood pressure, cholesterol, high-density lipoprotein, and low-density lipoproteins, did not differ between baseline and post-treatment time points. Modified Shenzhuo formula could reduce 24-hour urinary protein excretion in patients with DKD. The formula maybe had the potential advantages on glomerular filtration rate, creatinine reciprocal

    We previously observed 80.7% seropositivity and a significant interaction between gender and hepatitis A virus (HAV) vaccine type (Havrix vs. Epaxal) on the seropositivity approximately 11 months after single-dose HAV vaccinations in Korean young adults. Our objective was to evaluate seropositivity approximately 2 years after a single-dose HAV vaccination and the influence of demographic characteristics on seropositivity, including the interaction between gender and vaccine type. Seronegative medical school students were randomly vaccinated with Havrix or Epaxal. Based on a total serum anti-HAV antibody titer cutoff of 20 IU/mL, 338 participants (76.0%) of the 445 vaccinees were seropositive 20-25 months after a single-dose HAV vaccination. The seropositive rates were similar after vaccination with Havrix (77.0%) and Epaxal (74.9%). Univariate analysis indicated that female (p = 0.052) and less obese (p < 0.001) participants had a higher seropositive rate, whereas other characteristics such as age, alcohol use, smoking history, vaccine type, and follow-up duration were not associated with seropositivity. Multivariate analysis indicated that women (p = 0.026) and participants with moderate alcohol use (p < 0.001) showed significantly higher seropositive rates than men and participants with no or low alcohol use, respectively. The seropositive rates after vaccination with Havrix and Epaxal were 70.9% and 67.5% in men and 87.7% and 91.3% in women, respectively (p for interaction = 0.304). Compared with the seropositive rate approximately 11 months after vaccination, the seropositive rate decreased substantially only in men in the Havrix group (11.0% points), and consequently, the interaction between gender and vaccine type disappeared while seropositivity remained high (87.7% and 91.3% in Havrix and Epaxal groups, respectively) among women approximately 2 years after vaccination. Further studies are needed to assess whether the seropositive rate would be maintained in

    The interest in cervical total disc replacement (TDR) as an alternative to the so-far gold standard in the surgical treatment of degenerative disc disease (DDD), e.g anterior cervical discectomy and fusion (ACDF), is growing very rapidly. Many authors have established the fact that ACDF may result in progressive degeneration in adjacent segments. On the contrary, but still theoretically, preservation of motion with TDR at the surgically treated level may potentially reduce the occurrence of adjacent-level degeneration (ALD). The authors report the intermediate results of an undergoing multicentre prospective study of TDR with Mobi-C® prosthesis. The aim of the study was to assess the safety and efficacy of the device in the treatment of DDD and secondary to evaluate the radiological status of adjacent levels and the occurrence of ossifications, at 2-year follow-up (FU). 76 patients have performed their 2-year FU visit and have been analyzed clinically and radiologically. Clinical outcomes (NDI, VAS, SF-36) and ROM measurements were analyzed pre-operatively and at the different post-operative time-points. Complications and re-operations were also assessed. Occurrences of heterotopic ossifications (HOs) and of adjacent disc degeneration radiographic changes have been analyzed from 2-year FU X-rays. The mean NDI and VAS scores for arm and neck are reduced significantly at each post-operative time-point compared to pre-operative condition. Motion is preserved over the time at index levels (mean ROM = 9° at 2 years) and 85.5% of the segments are mobile at 2 years. HOs are responsible for the fusion of 6/76 levels at 2 years. However, presence of HO does not alter the clinical outcomes. The occurrence rate of radiological signs of ALD is very low at 2 years (9.1%). There has been no subsidence, no expulsion and no sub-luxation of the implant. Finally, after 2 years, 91% of the patients assume that they would undergo the procedure again. These intermediate

    The incidence of chronic thromboembolic pulmonary hypertension (CTEPH) after pulmonary embolism (PE) is relevant for management decisions but is currently unknown.We performed a meta-analysis of studies including consecutive PE patients followed for CTEPH. Study cohorts were predefined as "all comers", "survivors" or "survivors without major comorbidities". CTEPH incidences were calculated using random effects models.We selected 16 studies totalling 4047 PE patients who were mostly followed up for >2-years. In 1186 all comers (two studies), the pooled CTEPH incidence was 0.56% (95% CI 0.1-1.0). In 999 survivors (four studies) CTEPH incidence was 3.2% (95% CI 2.0-4.4). In 1775 survivors without major comorbidities (nine studies), CTEPH incidence was 2.8% (95% CI 1.5-4.1). Both recurrent venous thromboembolism and unprovoked PE were significantly associated with a higher risk of CTEPH, with odds ratios of 3.2 (95% CI 1.7-5.9) and 4.1 (95% CI 2.1-8.2) respectively. The pooled CTEPH incidence in 12 studies that did not use right heart catheterisation as the diagnostic standard was 6.3% (95% CI 4.1-8.4).The 0.56% incidence in the all-comer group probably provides the best reflection of the incidence of CTEPH after PE on the population level. The ∼3% incidences in the survivor categories may be more relevant for daily clinical practice. Studies that assessed CTEPH diagnosis by tests other than right heart catheterisation provide overestimated CTEPH incidences.

The patient's respiratory status ultimately declined and he developed respiratory failure. Imaging suggested pulmonary edema as well as a left-sided pneumonia. Echocardiogram showed pulmonary hypertension and airway exam via direct fiberoptic bronchoscopy revealed tracheomalacia and bronchomalacia. He developed acute respiratory distress syndrome (ARDS) and remained intubated for ten days. This case highlights the association between congenital upper body abnormalities with cranial nerve dysfunction and the development of POPE with delayed resolution of symptoms. Patients with upper body abnormalities as above are at great risk of postoperative complications and should therefore be managed in a tertiary-care facility. PMID:26942029

    We assessed the prospective association of risk factors for eating and body image disturbances after a 2-year follow-up in a community sample of Spanish adolescent girls. The participants included 128 Spanish girls aged 12-14, who took part in a 28-month prospective study. Aspects assessed were eating attitudes (Eating Attitudes Test), influence of the body shape model (questionnaire on influences of the aesthetic body shape model), extreme weight-control behaviors (Eating Disorder Examination-Questionnaire), body image (Body Image Questionnaire) and Body Mass Index (BMI). BMI, extreme weight-control behaviors and body image problems emerged as potential predictors of an increase in eating disturbances. An increased influence of the thinness model was significantly associated with reduced body satisfaction and body image problems. Preventive programs are needed to contribute reducing the impact of sociocultural influences with regard to thinness, the use of extreme weight-control behaviors and overweight in adolescents.

    Restricted, repetitive and stereotyped patterns of behavior, interests and activities [RRBs] are among the core symptoms of autism spectrum disorders (ASD). Previous studies have indicated that RRBs differentiate ASD from other developmental disorders and from typical development. This study examined the presentation of RRBs as reported on the Repetitive Behavior Scale-Revised, a caregiver report, in children with ASD [separated into autism and Pervasive Developmental Disorder-Not Otherwise Specified groups] compared with children with nonspectrum developmental delays or typical development. We examined the role of age, cognitive functioning, sex and social communication impairment as they relate to RRBs. The stability of RRBs in children with autism was also examined over the course of 2 years. Results of the study confirmed that the amount and type of RRBs differs by diagnosis. Age, cognitive functioning, sex and social-communication impairment were not significant correlates. Among children with autism, RRBs remained stable over time.

    High chairs are commonly used to feed children after 6 months. Related injuries are oftentime minor and rarely leading to death. We describe a case of a 2-year-old female child who used to jump alone on her high chair and also had the habit to fasten the straps by herself. Her mother found her hanging by the waist straps. A thorough investigation showed that she climbed her high chair and fastened the waist straps but not the crotch one. The girl slid down into the seat, trapping her neck in the waist straps and thus resulting in hanging. In here, we concluded that the victim's death was caused by asphyxia, itself, caused by accidental hanging. The present case is of a special interest because of the rare similar cases reported. This case suggests that a correct restraint use and a close supervision would have prevented such a fatal issue.

    Creation of computer monitoring systems (CMS) for operating rooms is one of the most important spheres of personal computer employment in anesthesiology. The authors developed a PC RS/AT-based CMS and effectively used it for more than 2 years. This system permits comprehensive monitoring in cardiosurgical operations by real time processing the values of arterial and central venous pressure, pressure in the pulmonary artery, bioelectrical activity of the brain, and two temperature values. Use of this CMS helped appreciably improve patients' safety during surgery. The possibility to assess brain function by computer monitoring the EEF simultaneously with central hemodynamics and body temperature permit the anesthesiologist to objectively assess the depth of anesthesia and to diagnose cerebral hypoxia. Automated anesthesiological chart issued by the CMS after surgery reliably reflects the patient's status and the measures taken by the anesthesiologist.

    Few studies have analysed factors that predict the ultimate clinical diagnosis in first-episode psychosis (FEP), and none has included cognitive factors. Eighty-six FEP patients and 34 healthy controls were recruited and followed up for two years. Positive and negative symptoms, depression, mania, duration of untreated psychosis (DUP), premorbid functioning, functional outcome and neurocognition were assessed over 2 years. Logistic regression models revealed that Wisconsin Card Sorting Test correctly distinguished the patients ultimately diagnosed with schizophrenia (87%) from those with bipolar disorder (80%) and those with other psychoses (85%), for an overall correct-diagnosis rate of 84.4%. The prediction was stable despite the inclusion of clinical and affective symptoms, DUP, clinical impression, and functional outcome scores. Results highlight the importance of reconsidering neurocognition as a diagnostic criterion for psychosis and schizophrenia.

    Parents commonly label objects on television and for some programs, verbal labels are also provided directly via voice-over. The present study investigated whether toddlers' imitation performance from television would be facilitated if verbal labels were presented on television via voice-over or if they were presented by parents who were co-viewing with their toddlers. Sixty-one 2-year olds were randomly assigned to one of four experimental groups (voice-over video, parent video, parent video no label, parent live) or to a baseline control condition. Toddlers were tested with novel objects after a 24h delay. Although, all experimental groups imitated significantly more target actions than the baseline control group, imitation was facilitated by novel labels regardless of whether those labels were provided by parents or by voice-over on television. These findings have important implications for toddler learning from television.

    Young children are at risk of iron deficiency and subsequent anaemia, resulting in long-term consequences for cognitive, motor and behavioural development. This study aimed to describe the iron intakes, status and determinants of status in 2-year-old children. Data were collected prospectively in the mother-child Cork BASELINE Birth Cohort Study from 15 weeks' gestation throughout early childhood. At the 24-month assessment, serum ferritin, haemoglobin and mean corpuscular volume were measured, and food/nutrient intake data were collected using a 2-day weighed food diary. Iron status was assessed in 729 children (median [IQR] age: 2.1 [2.1, 2.2] years) and 468 completed a food diary. From the food diary, mean (SD) iron intakes were 6.8 (2.6) mg/day and 30% had intakes < UK Estimated Average Requirement (5.3 mg/day). Using WHO definitions, iron deficiency was observed in 4.6% (n = 31) and iron deficiency anaemia in five children (1.0%). Following an iron series workup, five more children were diagnosed with iron deficiency anaemia. Twenty-one per cent had ferritin concentrations <15 µg/L. Inadequate iron intakes (OR [95% CI]: 1.94 [1.09, 3.48]) and unmodified cows' milk intakes ≥ 400 mL/day (1.95 [1.07, 3.56]) increased the risk of low iron status. Iron-fortified formula consumption was associated with decreased risk (0.21 [0.11, 0.41] P < 0.05). In this, the largest study in toddlers in Europe, a lower prevalence of low iron status was observed than in previous reports. Compliance with dietary recommendations to limit cows' milk intakes in young children and consumption of iron-fortified products appears to have contributed to improved iron status at two years.

    In the interpretation of dietary trends, it is important to consider the potential effect of modifications in the dietary assessment method. Therefore, our objective was to explore the comparability of data obtained at two time points by a semi-quantitative FFQ (SFFQ) which has had slight modifications over time. In the national dietary surveys among Norwegian 2-year-olds, diet was assessed by an SFFQ which underwent modifications between the 1999 survey and the 2007 survey. In the present study, fifty-nine families with a 2-year-old child participated by completing both the SFFQ in a crossover design within a month's time. With regard to the reported intake of energy and nutrients, the largest significant differences observed between the two questionnaires were for carbohydrates and added sugar. According to intake of food groups, significant differences were observed for five out of sixteen food groups. Spearman's correlation coefficients for energy, nutrients and food groups ranged from 0.43 (Ca) to 0.85 (soft drinks). Most Bland-Altman plots indicated broad limits of agreement. The differences between the two questionnaires can be explained by changes in the questionnaires, changes in the food composition databases used and random variation. Comparing differences between the questionnaires by maternal educational level, number of children and type of day care revealed minor differences. In conclusion, this study showed that at the group level there was reasonable comparability between the two questionnaires, except for carbohydrates, added sugar and some food groups. Moreover, there were moderate to high correlations for energy, nutrients and food groups.

    Objective To examine the extent to which weight gain and weight status in the first 2 years of life relate to the risk of neurodevelopmental impairment in extremely preterm infants. Study Design In a cohort of 1070 infants born between 23 and 27 weeks’ gestation, we examined weight gain from 7-28 days of life (in quartiles) and weight z-score at 12 and 24 months corrected age (in categories: <−2; ≥−2, <−1; ≥1, <1; ≥1) in relation to these adverse neurodevelopmental outcomes: Bayley-II mental development index <55, Bayley-II psychomotor development index <55, cerebral palsy, Gross Motor Function Classification System (GMFCS) ≥1 (cannot walk without assistance), microcephaly. We adjusted for confounders in logistic regression, stratified by sex, and performed separate analyses including the entire sample, and excluding children unable to walk without assistance (motor impairment). Results Weight gain in the lowest quartile from 7-28 days was not associated with higher risk of adverse outcomes. Children with a 12-month weight z-score <−2 were at increased risk for all adverse outcomes in girls, and for microcephaly and GMFCS ≥1 in boys. However, excluding children with motor impairment attenuated all associations except that of weight z-score <−2 with microcephaly in girls. Similarly, most associations of low weight z-score at 24 months with adverse outcomes were attenuated with exclusion of children with motor impairment. Conclusion Excluding children who have gross motor impairment appears to eliminate the association of low weight status with neurodevelopmental impairments at 2 years in extremely preterm infants.

    Anxious youth are at heightened risk for subsequent development of depression; however, little is known regarding which anxious youth are at the highest prospective risk. Biased attentional patterns (e.g., vigilance and avoidance of negative cues) are implicated as key mechanisms in both anxiety and depression. Aberrant attentional patterns may disrupt opportunities to effectively engage with, and learn from, threatening aspects of the environment during development and/or treatment, compounding risk over time. Sixty-seven anxious youth (age 9–14; 36 female) completed a dot-probe task to assess baseline attentional patterns provoked by fearful-neutral face pairs. The time course of attentional patterns both during and after threat was assessed via eyetracking and pupilometry. Self-reported depressive and anxiety symptoms were assessed two years after the conclusion of a larger psychotherapy treatment trial. Eyetracking patterns indicative of threat avoidance predicted greater 2-year depression scores, over and above baseline and post-treatment symptoms. Sustained, post-threat pupillary avoidance (reflecting preferential neural engagement with the neutral relative to the previously threatening location) predicted additional variance in depression scores, suggesting sustained avoidance in the wake of threat further exacerbated risk. Identical eyetracking and pupil indices were not predictive of anxiety at 2 years. These biobehavioral markers imply that avoidant attentional processing in the context of anxiety may be a gateway to depression across a key maturational window. Excessive avoidance of threat could interfere with acquisition of adaptive emotion regulation skills during development, culminating in the broad behavioral deactivation that typifies depression. Prevention efforts explicitly targeting avoidant attentional patterns may be warranted. PMID:26595463

    Background: A study was undertaken to evaluate exacerbations and their impact on the health related quality of life (HRQL) of patients with chronic obstructive pulmonary disease (COPD). Methods: A 2 year follow up study was performed in 336 patients with COPD of mean (SD) age 66 (8.2) years and mean (SD) forced expiratory volume in 1 second (FEV1) 33 (8)% predicted. Spirometric tests, questions regarding exacerbations of COPD, and HRQL measurements (St George's Respiratory Questionnaire (SGRQ) and SF-12 Health Survey) were conducted at 6 month intervals. Results: A total of 1015 exacerbations were recorded, and 103 (30.7%) patients required at least one hospital admission during the study. After adjustment for baseline characteristics and season of assessment, frequent exacerbations had a negative effect on HRQL in patients with moderate COPD (FEV1 35–50% predicted); the change in SGRQ total score of moderate patients with ⩾3 exacerbations was almost two points per year greater (worse) than those with <3 exacerbations during the follow up (p = 0.042). For patients with severe COPD (FEV1 <35% predicted) exacerbations had no effect on HRQL. The change in SGRQ total score of patients admitted to hospital was almost 2 points per year greater (worse) than patients not admitted, but this effect failed to show statistical significance in any severity group. There was a significant and independent seasonal effect on HRQL since SGRQ total scores were, on average, 3 points better in measurements performed in spring/summer than in those measured in the winter (p<0.001). Conclusions: Frequent exacerbations significantly impair HRQL of patients with moderate COPD. A significant and independent effect of seasonality was also observed. PMID:15115864

    Quality control is very important in relation to invasive and lengthy treatments, such as integrated orthodontic and surgical correction of dentofacial deformities. The aim of this cross-sectional study was to compare self-reported somatosensory disturbances and quantitative sensory testing (QST) findings between two groups of patients and a healthy control group (n = 24); one group (n = 21) scheduled for bimaxillary orthognathic surgery (BOS) (pre-op) and one group (n = 24) examined 1(1/2) years after BOS (post-op). Self-reported data on pain and somatosensory disturbances were collected, and QST was performed at six trigeminal and one extratrigeminal site. Sensitivity to brush stroke, tactile stimuli, pinprick, two-point-discrimination threshold (2P-DT), pinch pain threshold (PiPT) and pressure pain threshold (PPT) was evaluated. Results were analysed with anovas, Spearman's Correlation, and chi square tests. Eight per cent of post-op patients reported intra-oral, 46% extra-oral, and 46% no somatosensory disturbances. Sensitivity to brush stroke, pinprick and 2P-DT was significantly increased at all examination sites in the post-op patients compared with healthy controls (P < 0.002). Tactile thresholds and PPT did not differ between groups (P > 0.071). Pinch pain threshold were decreased in pre-op patients compared with controls (P < 0.040). Self-reported somatosensory disturbances were not correlated with QST findings. In conclusion; 1(1/2) years after BOS, a large proportion of patients reported somatosensory disturbances and was hypersensitive to mechanical stimuli when compared with pre-op patients and healthy controls. Pre-op patients showed minor somatosensory changes. In addition to patients serving as their own control in prospective studies, a healthy control group and extratrigeminal control sites should be included in future studies.

    Are there differences in patterns of practice between actively practising physicians who have been certified after a 2-year family practice residency and matched physicians without certification who have completed the standard 1-year internship? With the use of billing files prepared by the British Columbia Medical Association a group of 65 family practice certificants in active practice in British Columbia was compared with a control group of 130 internship trainees matched by year and school of graduation, category of billing (i.e., solo or group) and region. A wide range of practice features was assessed for the fiscal years 1984-85, 1985-86 and 1986-87. No differences were detected between the groups in 1986-87 for the following practice variables: number of patients (1888 and 1842 respectively), number of personal services billed for (7265 and 7173), number of personal services per patient (3.9), amount of funding for personal services ($140,192 and $140,100) and amount per patient for personal services ($77 and $79). Age-adjusted costs for male and female patients were similar in the two groups. Of six services thought to be influenced by type of training, only maternity care generated a significantly higher number of billings in the study group (341 v. 249). These results suggest that there is no demonstrable effect of training on patterns of practice. However, the question of the effect of training on quality of care and whether the 2-year residency may have a longer effect on practice patterns should be the focus of future research.

    Objective This study aims to validate a Food Frequency Questionnaire (FFQ), specifically designed to retrospectively estimate dietary intake and supplement consumption during the first two years of life in children from resource poor households in semi-rural Mexico. Methods The FFQ querying about diet during the first 2 years of life was administered to mothers of children (N=84), who participated in a prospective study 3 to 5 years earlier, in which complementary feeding practice questionnaires and 24-hour recall (24hrR) were collected at several time points during the first 2 years of life to evaluate dietary and vitamin supplement intake. The resulting FFQ data were compared to intake data collected during the original study using Spearman correlations, deattenuated correlations and Wilcoxon signed-rank tests. Results Total energy intake, as estimated by the retrospective and original instruments, did not differ in the second year (Yr2); correlations between the measures were significant (r=0.40, p<0.001). The 24hrR and FFQ-Yr2 were significantly correlated for dietary intake of vitamins B6, B12 (p<0.001) and folate (p<0.01); however, after including vitamin supplement intake, the two dietary instruments were correlated only for vitamins A and B12 (p<0.05). Conclusions The FFQ provides a reasonable estimate of a child’s dietary intake of energy and key micronutrients during the second year of life, and permits accurate ranking of intake 3 to 5 years after birth.

    Acrylamide is an industrial chemical used to manufacture polymers, and is produced in foods during cooking at high heat. Hemoglobin adducts provide a long-lived dosimeter for acrylamide and glycidamide. This study determined acrylamide and glycidamide hemoglobin adducts (AAVal and GAVal) during a lifetime carcinogenesis bioassay. Exposure to acrylamide in drinking water began in utero in pregnant rats on gestation day 6. Dams were administered acrylamide until weaning, and male and female F1 rats were exposed for a further 104 weeks. Acrylamide concentration in drinking water was adjusted to provide a constant dose of 0.5, 1.5, and 3 mg/kg/day. Blood was collected from animals euthanized at 2, 60, 90, and 120 days and 53, 79, and 104 weeks after weaning. Low levels of AAVal and GAVal at postnatal day 24 suggested that little exposure to acrylamide occurred by placental or lactational transfer, and extensive metabolism to glycidamide occurred with a GAVal:AAVal ratio of 4. Adduct levels varied somewhat from 60 days to 2 years, with a GAVal:AAVal ratio of approximately 1. Adduct formation/day estimated at each timepoint at 3 mg/kg/day for AAVal was 1293 ± 220 and 1096 ± 338 fmol/mg/day for male and female rats, respectively. Adduct formation per day estimated at each timepoint at 3 mg/kg/day for GAVal was 827 ± 78 fmol/mg/day for male rats, and 982 ± 222 fmol/mg/day for female rats. The study has provided estimates of linearity for dose response, and variability in internal dose throughout an entire 2-year bioassay, including the early phases of pregnancy and lactation.

    Linear growth from birth to 2 years of children enrolled in the World Health Organization Multicentre Growth Reference Study was similar despite substantial parental height differences among the six study sites. Within-site variability in child length attributable to parental height was estimated by repeated measures analysis of variance using generalized linear models. This approach was also used to examine relationships among selected traits (e.g. breastfeeding duration and child morbidity) and linear growth between 6 and 24 months of age. Differences in intergenerational adult heights were evaluated within sites by comparing mid-parental heights (average of the mother's and father's heights) to the children's predicted adult height. Mid-parental height consistently accounted for greater proportions of observed variability in attained child length than did either paternal or maternal height alone. The proportion of variability explained by mid-parental height ranged from 11% in Ghana to 21% in India. The average proportion of between-child variability accounted for by mid-parental height was 16% and the analogous within-child estimate was 6%. In the Norwegian and US samples, no significant differences were observed between mid-parental and children's predicted adult heights. For the other sites, predicted adult heights exceeded mid-parental heights by 6.2-7.8 cm. To the extent that adult height is predicted by height at age 2 years, these results support the expectation that significant community-wide advances in stature are attainable within one generation when care and nutrition approximate international recommendations, notwithstanding adverse conditions likely experienced by the previous generation.

    Background The physical work demands of construction work can be reduced using ergonomic measures. The aim of this study was to evaluate the use of ergonomic measures related to musculoskeletal disorders (MSDs) among construction workers. Methods A questionnaire was sent at baseline and 2 years later to 1,130 construction workers. We established (1) the proportion of workers reporting an increase in their use of ergonomic measures, (2) the proportion of workers reporting a decrease in MSDs, (3) the relative risk for an increase in the use of ergonomic measures and a decrease in MSDs, and (4) workers' knowledge and opinions about the use of ergonomic measures. Results At follow-up, response rate was 63% (713/1,130). The proportion of workers using ergonomic measures for vertical transport increased (34%, 144/419, p < 0.01); for measures regarding horizontal transport and the positioning of materials, no change was reported. The proportion of workers reporting shoulder complaints decreased (28%, 176/638, p = 0.02). A relationship between the use of ergonomic measures and MSDs was not found; 83% (581/704) of the workers indicated having sufficient knowledge about ergonomic measures. Lightening the physical load was reported to be the main reason for using them. Conclusion Only the use of ergonomic measures for vertical transport increased over a 2-year period. No relationship between the use of ergonomic measures and MSDs was found. Strategies aimed at improving the availability of ergonomic equipment complemented with individualized advice and training in using them might be the required next steps to increase the use of ergonomic measures.

    In August 2014 the ROSETTA spacecraft rendezvoused with comet 67P/Churyumov-Gerasimenko and escorted it for more than 2 years along its orbit around the Sun from 4 AU preperihelion to 4 AU postperihelion. During this time the COSIMA instrument (COmetary Secondary Ion Mass Analyser) onboard ROSETTA collected more than 25,000 dust particles in the vicinity of the comet nucleus. All these particles were collected on a number of specially designed metal target plates which were regularly imaged with a microscope (14 µm pixel/pixel resolution, 14mm x 14mm FOV) enabling the analysis of their individual morphologies, certain physical properties, e.g. tensile strength, albedo, as well as the overall flux and size distribution of the dust entering the COSIMA instrument. The images were also used to choose which of the particles shall go through compositional measurements with the time-of-flight mass spectrometer (sometimes repeated at a later time). All these investigations were done over 2 years. This allows to study the compositional and morphological differences of the particles collected at the various sections of the pre- and postperihelion orbit, the evolution of the morphology of the particles on the target plate with time, and the search for spatial heterogeneity of the composition within a particle by taking mass spectra at different locations on the same particle. An overview will be given on the available data and the results obtained so far in view to the analysis of dust composition and morphology, as well as dust flux and size distribution along the orbit.

    The aim of this study was to analyse the predictive power of several clinical baseline parameters and the de-/remineralisation properties of in vivo etched sites measured with quantitative light-induced fluorescence (QLF) for subsequent 2-year caries increment. At baseline, in 44 children (8.23 ± 1.5 years) two areas (diameter 2 mm) of the buccal surface of a primary posterior tooth were etched with 36% phosphoric acid gel for 1 and 4 min, respectively. The etched sites were analysed immediately after etching (ΔQ1) and 24 h (ΔQ2) later by QLF. Additionally, caries status (deft/DMFT and initial caries), approximal plaque, bleeding on probing, and the patient's current use of fluorides were recorded. In the 2-year follow-up, 29 children were re-assessed. After clinical examination, the caries increment was calculated (ΔDMFT) and correlated with the baseline clinical variables and the QLF readings. Results showed a significant positive correlation between ΔQ(1 min) and the ΔDMFT (r = 0.44, p = 0.02). The ΔDMFT was significantly correlated with the baseline deft (r = 0.56, p = 0.002), cavitated active caries lesions (r = 0.52, p = 0.003), and filled teeth (r = 0.53, p = 0.003). In a regression analysis the use of fluoridated salt (SC = -0.10) and fluoride gel (SC = -0.14) were negatively associated with ΔDMFT. In conclusion, these findings suggest that the demineralisation properties of the etched sites and the outcome of the 24-hour measurements with QLF are significantly associated with caries increment. Previous caries experience strongly correlated with caries increment in this group of children.

    47,XXX syndrome is among the most common sex chromosomal disorders; however, apart from screening surveys, epidemiological data are limited. We report data on 136 women diagnosed with 47,XXX or a compatible karyotype in Denmark during 1963-2008. We identified an incidence of 10.7 per 100,000 liveborn girls, which was lower than expected and was stable during the study period. Age at diagnosis ranged from 0 to 73 years, with a diagnostic delay of 18.2 years or more in half the 47,XXX persons. We compared persons with 47,XXX with an age-matched cohort of the female background population (born same year and month), identified in Statistics Denmark (n = 13,400). Mortality was significantly increased in total with a hazard ratio of 2.5 (1.6-3.9), corresponding to a difference in median survival of 7.7 years. When we divided causes of death into 19 chapters according to the International Classification of Diseases, a generally increased mortality was identified in all informative chapters. Furthermore, we identified significantly increased mortality in cardiovascular diseases, in the chapter concerning chromosomal and congenital defects, and in the chapter of unspecified diseases. Better delineation of the clinical phenotype of 47,XXX is needed; available information does not readily explain the increased mortality.

    Protestant missionaries (n = 360) serving in sub-Saharan Africa between 1967-1984 were studied to determine the risk of hepatitis A virus (HAV) and hepatitis B virus (HBV) infection. Personnel were serologically screened for antibody to both the hepatitis A virus (anti-HAV) and the surface antigen to the hepatitis B virus (anti-HBs) prior to departure, periodically during service abroad, and upon completion of their African tour. Rates of seroconversion were used as measures of the incidence of infection. Prior to service, 16% of the staff had anti-HAV and 3% had anti-HBs; post-service rates were 42% and 26%, respectively. Over 90% of the staff with greater than 20 years of service were seropositive for anti-HAV. For both viruses, the infection rate was highest during the first 1-2 years of service, when 28% of those susceptible to HAV and 11% of those susceptible to HBV became infected. Over the next decade, the median annual attack rate was 5.4% for HAV and 4.2% for HBV. Differences in the missionary HBV infection rate among the various African nations served tended to reflect differences in the magnitude of chronic HBV carriage among indigenous population groups. We conclude that missionaries to sub-Saharan Africa are at enhanced risk of both HAV and HBV infection, and that all should receive passive immunization with immune globulin and active immunization with hepatitis B vaccine.

    Knowledge of the incidence of spontaneous congenital abnormalities is critical for the accurate interpretation of findings in teratogenicity studies in any species. In this paper, results of the examination of 1739 neonatal Göttingen Minipigs are presented. Over the 2-year period under consideration, the incidence of external and visceral malformations was less than 0.2 and 0.1%, respectively. The most common external malformations were syndactyly, limb hyperflexion, domed head and scoliosis. The most common internal malformations were undescended testes, ventricular septal defect, diaphragmatic hernia and atrial septal defects. Pentadactyly and variation in the aortic arch's bifurcation (absent truncus bicaroticus) were the most common variations. These data will help support the use of the Göttingen Minipig as a non-rodent species in embryofetal development studies where concerns persist about the availability of background data.
