Doubly stochastic radial basis function methods

NASA Astrophysics Data System (ADS)

Yang, Fenglian; Yan, Liang; Ling, Leevan

2018-06-01

We propose a doubly stochastic radial basis function (DSRBF) method for function recoveries. Instead of a constant, we treat the RBF shape parameters as stochastic variables whose distribution were determined by a stochastic leave-one-out cross validation (LOOCV) estimation. A careful operation count is provided in order to determine the ranges of all the parameters in our methods. The overhead cost for setting up the proposed DSRBF method is O (n2) for function recovery problems with n basis. Numerical experiments confirm that the proposed method not only outperforms constant shape parameter formulation (in terms of accuracy with comparable computational cost) but also the optimal LOOCV formulation (in terms of both accuracy and computational cost).

2016-01-01

Prospective controlled evidence supporting the efficacy of long-term exercise to prevent physical decline and reduce falls in old age is lacking. The present study aimed to assess the effects of long-term music-based multitask exercise (i.e., Jaques-Dalcroze eurhythmics) on physical function and fall risk in older adults. A 3-year follow-up extension of a 1-year randomized controlled trial (NCT01107288) was conducted in Geneva (Switzerland), in which 134 community-dwellers aged ≥65 years at increased risk of falls received a 6-month music-based multitask exercise program. Four years following original trial enrolment, 52 subjects (baseline mean ± SD age, 75 ± 8 years) who (i) have maintained exercise program participation through the 4-year follow-up visit (“long-term intervention group”, n = 23) or (ii) have discontinued participation following original trial completion (“control group”, n = 29) were studied. They were reassessed in a blind fashion, using the same procedures as at baseline. At 4 years, linear mixed-effects models showed significant gait (gait speed, P = 0.006) and balance (one-legged stance time, P = 0.015) improvements in the long-term intervention group, compared with the control group. Also, long-term intervention subjects did better on Timed Up & Go, Five-Times-Sit-to-Stand and handgrip strength tests, than controls (P < 0.05, for all comparisons). Furthermore, the exercise program reduced the risk of falling (relative risk, 0.69; 95 % confidence interval, 0.5–0.9; P = 0.008). These findings suggest that long-term maintenance of a music-based multitask exercise program is a promising strategy to prevent age-related physical decline in older adults. They also highlight the efficacy of sustained long-term adherence to exercise for falls prevention. PMID:25148876

To determine if cantilever transforaminal lumbar interbody fusion (C-TLIF) using the crescent-shaped titanium interbody spacer (IBS) favors acquisition of segmental and lumbar lordosis even for degenerative spondylolisthesis (DS) on a long-term basis. We analyzed 23 consecutive patients who underwent C-TLIF with pedicle screw instrumentations fixed with compression for a single-level DS. Measurements on the lateral radiographs taken preoperatively, 2 weeks postoperatively and at final follow-up included disc angle (DA), segmental angle (SA), lumbar lordosis (LL), disc height (%DH) and slip rate (%slip). There was a good functional recovery with 100 % fusion rate at the mean follow-up of 62 months. Segmental lordosis (DA and SA) and %DH initially increased, but subsequently decreased with the subsidence of the interbody spacer, resulting in a significant increase (p = 0.046) only in SA from 13.2° ± 5.5° preoperatively to 14.7° ± 6.4° at the final follow-up. Changes of LL and %slip were more consistent without correction loss finally showing an increase of LL by 3.6° (p = 0.005) and a slip reduction by 6.7 % (p < 0.001). Despite the inherent limitation of placing the IBS against the anterior endplate of the upper vertebra in the presence of DS, the C-TLIF helped significantly restore segmental as well as lumbar lordosis on a long-term basis, which would be of benefit in preventing hypolordosis-induced back pain and the adjacent level disc disease.

Long-Term Use of Benzodiazepines and Nonbenzodiazepine Hypnotics, 1999-2014.

Kaufmann, Christopher N; Spira, Adam P; Depp, Colin A; Mojtabai, Ramin

2018-02-01

Clinical guidelines suggest that benzodiazepines (BZDs) and non-BZD hypnotics (NBHs) be used on a short-term basis. The authors examined trends in long-term BZD and NBH use from 1999 to 2014. Data included 82,091 respondents in the 1999-2014 waves of the National Health and Nutrition Examination Survey (NHANES). NHANES recorded medications used in the past 30 days on the basis of prescription bottles, and participants reported use duration. BZD and NBH use were categorized as short, medium, and long term, and time trends in use were assessed. BZD and NBH use increased from 1999 to 2014, driven by increases in medium- and long-term use, even after adjustment for age and race-ethnicity. In most years, only a fifth of current BZD or NBH users reported short-term use. Long-term BZD and NBH use has grown independent of U.S. demographic shifts. Monitoring of use is needed to prevent adverse outcomes.

There are doubts about the age limit for lung donors and the ideal donor has traditionally been considered to be one younger than 55 years. The objective of this study was to compare the outcomes in lung transplantation between organs from donors older and younger than 60 years. We performed a retrospective observational study comparing the group of patients receiving organs from donors 60 years or older (Group A) or younger than 60 years (Group B) between January 2007 and December 2011. Postoperative evolution and mortality rates, short-term and mid-term postoperative complications, and global survival rate were evaluated. We analysed a total of 230 lung transplants, of which 53 (23%) involved lungs from donors 60 years of age or older (Group A), and 177 (77%) were from donors younger than 60 years (Group B). Three (5.7%) patients from Group A and 14 patients (7.9%) from Group B died within 30 days (P = 0.58). The percentage of patients free from chronic lung allograft dysfunction at 1-3 years was 95.5, 74.3 and 69.3% for Group A, and 94.5, 84.8 and 73.3% for Group B, respectively (P = 0.47). There were no statistically significant differences between Groups A and B in terms of survival at 3 years, (69.4 vs 68.8%; P = 0.28). Our results support the idea that lungs from donors aged 60-70 years can be used safely for lung transplantation with comparable results to lungs from younger donors in terms of postoperative mortality and mid-term survival. © The Author 2014.

Wild Chimpanzees Exchange Meat for Sex on a Long-Term Basis

PubMed Central

Gomes, Cristina M.; Boesch, Christophe

2009-01-01

Humans and chimpanzees are unusual among primates in that they frequently perform group hunts of mammalian prey and share meat with conspecifics. Especially interesting are cases in which males give meat to unrelated females. The meat-for-sex hypothesis aims at explaining these cases by proposing that males and females exchange meat for sex, which would result in males increasing their mating success and females increasing their caloric intake without suffering the energetic costs and potential risk of injury related to hunting. Although chimpanzees have been shown to share meat extensively with females, there has not been much direct evidence in this species to support the meat-for-sex hypothesis. Here we show that female wild chimpanzees copulate more frequently with those males who, over a period of 22 months, share meat with them. We excluded other alternative hypotheses to exchanging meat for sex, by statistically controlling for rank of the male, age, rank and gregariousness of the female, association patterns of each male-female dyad and meat begging frequency of each female. Although males were more likely to share meat with estrous than anestrous females given their proportional representation in hunting parties, the relationship between mating success and sharing meat remained significant after excluding from the analysis sharing episodes with estrous females. These results strongly suggest that wild chimpanzees exchange meat for sex, and do so on a long-term basis. Similar studies on humans will determine if the direct nutritional benefits that women receive from hunters in foraging societies could also be driving the relationship between reproductive success and good hunting skills.

2018-03-06

The laparoscopic sleeve gastrectomy is now the most common bariatric operation in the United States and has become an established procedure in the armamentarium of the bariatric surgeon. However, this has happened without the strong support of long-term outcomes data, namely the rate of revision and durability of the weight loss. Newly published data from around the world are starting to show alarming trends in these 2 areas. This paper will examine the published and presented data with at least a 7-year follow-up. This is a meta-analysis on published data with at least 7 years of follow-up from the laparoscopic sleeve gastrectomy. Online published articles. We performed a meta-analysis of publications with at least 7 years of follow-up with the keywords "laparoscopic, bariatric, sleeve gastrectomy, sleeve, long-term, long, term, results, follow-up, follow up, conversion, 7 years, 8 years, 9 years, 10 years, 11 years." We queried the PubMed, MEDLINE, and ClinicalKey search engines, which included abstracts as well. The I 2 statistic was used to determine the heterogeneity across the studies. In presence of heterogeneity, a random effect model using the Dersimonian and Laird method was used to estimate the pooled estimates. The results were summarized using effect size along with a 95% confidence interval (CI). Meta-regression was also used to assess the effect of body mass index and follow-up years on the incidence of recidivism at ≥7 years. Nine cohort studies met the inclusion criteria, with a total of 2280 patients included initially. Only 652 patients had completed ≥7 years of follow-up. At ≥7 years, the long-term weight recidivism rate was estimated to be 27.8% (I 2 = .60%; 95% CI: 22.8%-32.7%) with a range of 14% to 37%. The overall revision rate was estimated to be 19.9% (I 2 = 93.8%; 95% CI: 11.3%-28.5%). This was broken down into 13.1% (I 2 = 93.8%; 95% CI: 5.6%-20.6%) due to weight regain (5 studies) and 2.9% (I 2 = 60.8%; 95% CI: 1%-4.9%) due to

The polynomial form of the scattering equations is an H -basis

We prove that the polynomial form of the scattering equations is a Macaulay H -basis. We demonstrate that this H -basis facilitates integrand reduction and global residue computations in a way very similar to using a Gröbner basis, but circumvents the heavy computation of the latter. As an example, we apply the H -basis to prove the conjecture that the dual basis of the polynomial scattering equations must contain one constant term.

This is the first study to evaluate the long-term effectiveness of a school-based prevention program in Germany. The aim is to determine the long-term effects of the primary prevention program PriMa (Primary prevention of anorexia nervosa in preadolescent girls) on disordered eating and body self-esteem from childhood to young adulthood. PriMa was conducted and successfully evaluated in a quasi-experimental pre-post design with a control group from 2007 to 2008 consisting of 11-13year old girls (N=1508) from Thuringian schools in Germany. Seven to eight years after the intervention, the same cohort (mean age 19.8years) was invited to complete an online survey. Disordered eating (EAT-26), body self-esteem (FBeK) and BMI were assessed via self-report. The response rate at seven-to-eight-year follow-up was very low (7%). Data of N=100 girls were analyzed. Concerning changes in disordered eating, results revealed no significant long-term effect of PriMa seven to eight years after the intervention. During this time, disordered eating remained stable without a significant increase or decrease. Regarding changes in body self-esteem, group courses differed significantly from each other. The results revealed a significant main effect of group, indicating significant differences in changes of body self-esteem between the intervention and the control group. Following the analysis of these changes of body self-esteem over time, it was found that the intervention group revealed an increase of body self-esteem after program participation and remained stable over time. By contrast, the control group revealed a decrease of body self-esteem over time. Long-term intervention effects of PriMa could be found for body self-esteem but not for disordered eating. The findings suggest that PriMa prevented a decrease of body self-esteem from childhood to young adulthood. For a broader dissemination it is necessary to implement prevention programs consistently in school settings. In order to

Background Selective dorsal rhizotomy (SDR) is a well accepted neurosurgical procedure performed for the relief of spasticity interfering with motor function in children with spastic cerebral palsy (CP). The goal is to improve function, but long-term outcome studies are rare. The aims of this study were to evaluate long-term functional outcomes, safety and side effects during five postoperative years in all children with diplegia undergoing SDR combined with physiotherapy. Methods This study group consisted of 35 children, consecutively operated, with spastic diplegia, of which 26 were Gross Motor Function Classification System (GMFCS) levels III–V. Mean age was 4.5 years (range 2.5–6.6). They were all assessed by the same multidisciplinary team at pre- and at 6, 12, 18 months, 3 and 5 years postoperatively. Clinical and demographic data, complications and number of rootlets cut were prospectively registered. Deep tendon reflexes and muscle tone were examined, the latter graded with the modified Ashworth scale. Passive range of motion (PROM) was measured with a goniometer. Motor function was classified according to the GMFCS and measured with the Gross Motor Function Measure (GMFM-88) and derived into GMFM-66. Parent's opinions about the children's performance of skills and activities and the amount of caregiver assistance were measured with Pediatric Evaluation Disability Inventory (PEDI). Results The mean proportion of rootlets cut in S2-L2 was 40%. Muscle tone was immediately reduced in adductors, hamstrings and dorsiflexors (p < 0.001) with no recurrence of spasticity over the 5 years. For GMFCS-subgroups I–II, III and IV–V significant improvements during the five years were seen in PROM for hip abduction, popliteal angle and ankle dorsiflexion (p = 0.001), capacity of gross motor function (GMFM) (p = 0.001), performance of functional skills and independence in self-care and mobility (PEDI) (p = 0.001). Conclusion SDR is a safe and effective method for

Prognostic markers of primary progressive multiple sclerosis evolution are needed. We investigated the added value of magnetic resonance imaging measures of brain and cervical cord damage in predicting long-term clinical worsening of primary progressive multiple sclerosis compared to simple clinical assessment. In 54 patients, conventional and diffusion tensor brain scans and cervical cord T1-weighted scans were acquired at baseline and after 15 months. Clinical evaluation was performed after 5 and 15 years in 49 patients. Lesion load, brain and cord atrophy, mean diffusivity and fractional anisotropy values from the brain normal-appearing white matter and grey matter were obtained. Using linear regression models, we screened the clinical and imaging variables as independent predictors of 15-year disability change (measured on the expanded disability status scale). At 15 years, 90% of the patients had disability progression. Integrating clinical and imaging variables at 15 months predicted disability changes at 15 years better than clinical factors at 5 years (R2 = 61% versus R2 = 57%). The model predicted long-term disability change with a precision within one point in 38 of 49 patients (77.6%). Integration of clinical and imaging measures allows identification of primary progressive multiple sclerosis patients at risk of long-term disease progression 4 years earlier than when using clinical assessment alone. © The Author (2017).

We study abilities of data-driven stochastic models constructed by nonlinear dynamical decomposition of spatially distributed data to quantitative (short-term) forecast of climate characteristics. We compare two data processing techniques: (i) widely used empirical orthogonal function approach, and (ii) nonlinear dynamical modes (NDMs) framework [1,2]. We also make comparison of two kinds of the prognostic models: (i) traditional autoregression (linear) model and (ii) model in the form of random ("stochastic") nonlinear dynamical system [3]. We apply all combinations of the above-mentioned data mining techniques and kinds of models to short-term forecasts of climate indices based on sea surface temperature (SST) data. We use NOAA_ERSST_V4 dataset (monthly SST with space resolution 20 × 20) covering the tropical belt and starting from the year 1960. We demonstrate that NDM-based nonlinear model shows better prediction skill versus EOF-based linear and nonlinear models. Finally we discuss capability of NDM-based nonlinear model for long-term (decadal) prediction of climate variability. [1] D. Mukhin, A. Gavrilov, E.

20 year long term air quality trends in Israel

NASA Astrophysics Data System (ADS)

Luria, M.

2017-12-01

The Israeli air monitoring network was established in the mid 1990's with dozens of measuring sites near most populated areas. During these past 20 years the Israel economy has increased significantly. The population grew by 30%, energy consumption and power generation by more than 40% and the number of motor vehicles increased by nearly 50%. Most of the fossil energy is consumed by the electric power industry that has changed immensely during this period. Until the early 2000's the vast majority of the electricity was generated from coal and heavy oil. However, during the last ten years natural gas has gradually becomes the major source for power generation and for most of the heavy industry. In the present study we examined the impact of these economic trends on the major criteria air pollution parameters; O3, NOx, SO2 and PM10. The analyses was based on the long term trend of median value (50th percentile) and the 90th percentile. The results revealed that SO2 levels throughout the country decreased to very low levels, with the 90th percentile near the detection limit. The levels of PM10, that are relatively high compare with other global regions, did not show any trend during the 20 year period. This is consistent with the fact that most particulate matter results from long range transport of dust from the surrounding deserts. The long term trend of NOx indicates a gradual and steady increase at most measuring sites, which is consistent with the increase of fossil fuel consumption. The increase in NOx levels is most likely the cause for the significant increase in O3 levels found at most sites in a few of them to levels that are considered as an environmental hazard.

Although adjustment disorder is frequently reported in clinical settings, scientific evidence is scarce regarding its impact on sickness absence and the variables associated with sickness absence duration. To report sickness absence duration and to identify predictors of long-term sickness absence in patients with adjustment disorder. This observational, prospective study included subjects with non-work-related sickness absence (>15 days) after a diagnosis of adjustment disorder. A stepwise logistic regression analysis was conducted to identify the best predictors of long-term sickness absence (≥ 6 months). There were 1182 subjects in the final analysis. The median duration of sickness absence due to adjustment disorder was 91 days. Twenty-two per cent of the subjects reported long-term sickness absence. After multivariate analysis, comorbidity (OR = 2.23, 95% CI 1.43-3.49), age (25-34 years old versus <25 years old: OR = 2.78, 95% CI 1.27-6.07; 35-44 years old versus <25 years old: OR = 3.70, 95% CI 1.71-7.99; 45-54 years old versus <25 years old: OR = 3.58, 95% CI 1.60-8.02; ≥ 55 years old versus <25 years old: OR = 6.35, 95% CI 2.64-15.31) and occupational level (blue collar versus white collar: OR = 1.52, 95% CI 1.10-2.09) remained significantly associated with long-term sickness absence. Comorbidity was the strongest predictor. It is possible to predict long-term sickness absence due to adjustment disorder on the basis of demographic, work-related and clinical information available during the basic assessment of the patient.

Interferometry is one of the central organizing principles of optics. Key to interferometry is the concept of optical delay, which facilitates spectral analysis in terms of time-harmonics. In contrast, when analyzing a beam in a Hilbert space spanned by spatial modes – a critical task for spatial-mode multiplexing and quantum communication – basis-specific principles are invoked that are altogether distinct from that of ‘delay’. Here, we extend the traditional concept of temporal delay to the spatial domain, thereby enabling the analysis of a beam in an arbitrary spatial-mode basis – exemplified using Hermite-Gaussian and radial Laguerre-Gaussian modes. Such generalized delays correspond to optical implementations of fractional transforms; for example, the fractional Hankel transform is the generalized delay associated with the space of Laguerre-Gaussian modes, and an interferometer incorporating such a ‘delay’ obtains modal weights in the associated Hilbert space. By implementing an inherently stable, reconfigurable spatial-light-modulator-based polarization-interferometer, we have constructed a ‘Hilbert-space analyzer’ capable of projecting optical beams onto any modal basis.

A new procedure for the optimization of the exponents, αj, of Gaussian basis functions, Ylm(ϑ,φ)rle-αjr2, is proposed and evaluated. The direct optimization of the exponents is hindered by the very strong coupling between these nonlinear variational parameters. However, expansion of the logarithms of the exponents in the orthonormal Legendre polynomials, Pk, of the index, j: ln αj=∑k=0kmaxAkPk((2j-2)/(Nprim-1)-1), yields a new set of well-conditioned parameters, Ak, and a complete sequence of well-conditioned exponent optimizations proceeding from the even-tempered basis set (kmax=1) to a fully optimized basis set (kmax=Nprim-1). The error relative to the exact numerical self-consistent field limit for a six-term expansion is consistently no more than 25% larger than the error for the completely optimized basis set. Thus, there is no need to optimize more than six well-conditioned variational parameters, even for the largest sets of Gaussian primitives.

Neurobiological Basis of Insight in Schizophrenia: A Systematic Review.

PubMed

Xavier, Rose Mary; Vorderstrasse, Allison

2016-01-01

Insight in schizophrenia is defined as awareness into illness, symptoms, and need for treatment and has long been associated with cognition, other psychopathological symptoms, and several adverse clinical and functional outcomes. However, the biological basis of insight is not clearly understood. The aim of this systematic review was to critically evaluate and summarize advances in the study of the biological basis of insight in schizophrenia and to identify gaps in this knowledge. A literature search of PubMed, CINAHL, PsycINFO, and EMBASE databases was conducted using search terms to identify articles relevant to the biology of insight in schizophrenia published in the last 6 years. Articles that focused on etiology of insight in schizophrenia and those that examined the neurobiology of insight in schizophrenia or psychoses were chosen for analysis. Articles on insight in conditions other than schizophrenia or psychoses and which did not investigate the neurobiological underpinnings of insight were excluded from the review. Twenty-six articles met the inclusion criteria for this review. Of the 26 articles, 3 focused on cellular abnormalities and 23 were neuroimaging studies. Preliminary data identify the prefrontal cortex, cingulate cortex, and regions of the temporal and parietal lobe (precuneus, inferior parietal lobule) and hippocampus as the neural correlates of insight. A growing body of literature attests to the neurobiological basis of insight in schizophrenia. Current evidence supports the neurobiological basis of insight in schizophrenia and identifies specific neural correlates for insight types and its dimensions. Further studies that examine the precise biological mechanisms of insight are needed to apply this knowledge to effective clinical intervention development.

Administration of oxandrolone, a nonaromatizable testosterone analog, to children for 12 months following severe burn injury has been shown to improve height, increase bone mineral content (BMC), reduce cardiac work, and augment muscle strength. Surprisingly, the increase in BMC persists well beyond the period of oxandrolone administration. This study was undertaken to determine if administration of oxandrolone for 2 years yields greater effects on long-term BMC and bone mineral density (BMD). Patients between 0 and 18 years of age with ≥30% of total body surface area burned were consented to an IRB-approved protocol and randomized to receive either placebo (n = 84) or 0.1 mg/kg oxandrolone orally twice daily for 24 months (n = 35). Patients were followed prospectively from the time of admission until 5 years postburn in a single-center, intent-to-treat setting. Height, weight, BMC, and BMD were recorded annually through 5 years postinjury. The long-term administration of oxandrolone for 16 ± 1 months postburn (range, 12.1-25.2 months) significantly increased whole-body (WB) BMC (p < 0.02) and lumbar spine (LS) BMC (p < 0.05); these effects were significantly pronounced for a longer time in patients who were in growth spurt years (7-18 years). When adjusted for height, sex, and age, LS BMD was found to significantly increase with long-term oxandrolone administration (p < 0.0009). Fewer patients receiving oxandrolone exhibited LS BMD z scores below -2.0 as compared with controls, indicating a significantly reduced risk for future fracture with oxandrolone administration. Long-term oxandrolone patients had significantly greater height velocity than controls throughout the first 2-year postburn (p < 0.05). No adverse side effects were attributed to the long-term administration of oxandrolone. A comparison of the current patients receiving long-term oxandrolone to previously described patients receiving 12 months of oxandrolone revealed that long-term oxandrolone

Short- and mid-term data on Roux-en-Y gastric bypass (RYGB) indicate sustained weight loss and improvement in co-morbidities. Few long-term studies exist, some of which are outdated, based on open procedures or different techniques. To investigate long-term weight loss, co-morbidity remission, nutritional status, and complication rates among patients undergoing RYGB. An academic, university hospital in the United States. Between October 2000 and January 2004, patients who underwent RYGB≥10 years before study onset were eligible for chart review, office visits, and telephone interviews. Revisional surgery was an endpoint, ceasing eligibility for study follow-up. Outcomes included weight loss measures and rates of co-morbidity remission, complications, and nutritional deficiencies. RYGB was performed in 328 patients with a mean preoperative body mass index of 47.5 kg/m(2). Of 294 eligible patients, 134 (46%) were contacted for follow-up at ≥ 10 years (10+Year follow-up). Mean percentage excess weight loss (%EWL) was 58.9% at 10+Year. Higher %EWL was achieved by non-super-obese versus super-obese (61.3% versus 52.9%, P = .034). Blood pressure, lipid panel, and hemoglobin A1c improved significantly. At 10 years, remission of co-morbidities was 46% for hypertension and hyperlipidemia and 58% for diabetes mellitus. Thirty patients (9%) had revisional surgery for weight regain. Sixty-four patients (19.5%) had long-term complications requiring surgery. All-cause mortality was 2.7%. Nutritional deficiencies were seen in 87% of patients. Weight loss after RYGB appears to be significant and sustainable, especially in the non-super-obese. Co-morbidities are improved, with a substantial number in remission a decade later. Nutritional deficiencies are almost universal. Copyright © 2016 American Society for Bariatric Surgery.

Aribit, F; Charissoux, J L; Arnaud, J P

2002-05-01

We studied the efficacy of papaine for treatment of herniated discs at a mean 10-year follow-up and compared results with other series and other treatments. From an initial group of 160 patients, 96 patients, 53 men and 43 women, mean age 39 years, were selected for evaluation. These patients had 46 L4L5 herniations and 50 L5S1 herniations. All 96 patients were operated in the same department and received the same dose of papaine under the same anesthesia conditions. All patients were followed regularly to 3 months postoperatively then were reviewed 3 to 17 years after surgery. Inquiries were made about return to work, pain, and activity. Physical examination and x-rays were obtained for all patients. There were no neurological complications in our series. Seventeen patients required a second procedure for sciatic pain. Most of the patients continued their normal occupational and social activities after papaine treatment, but many of them had chronic lumbar pain. Our results were comparable with series reporting a similar long follow-up. Surgery is more efficient than papaine but long-term results are equivalent. Chemopapaine treatment provided good long-term results in our patients, similar to surgery. Chemonucleolysis may be employed as first line treatment for young patients with non-excluded disc herniation with sciatic pain.

Solutions to Kuessner's integral equation in unsteady flow using local basis functions

1975-01-01

The computational procedure and numerical results are presented for a new method to solve Kuessner's integral equation in the case of subsonic compressible flow about harmonically oscillating planar surfaces with controls. Kuessner's equation is a linear transformation from pressure to normalwash. The unknown pressure is expanded in terms of prescribed basis functions and the unknown basis function coefficients are determined in the usual manner by satisfying the given normalwash distribution either collocationally or in the complex least squares sense. The present method of solution differs from previous ones in that the basis functions are defined in a continuous fashion over a relatively small portion of the aerodynamic surface and are zero elsewhere. This method, termed the local basis function method, combines the smoothness and accuracy of distribution methods with the simplicity and versatility of panel methods. Predictions by the local basis function method for unsteady flow are shown to be in excellent agreement with other methods. Also, potential improvements to the present method and extensions to more general classes of solutions are discussed.

To determine the outcome of chronic kidney disease (CKD) patients presenting for dialysis on the basis of referral to nephrologist. Observational study. Nephrology Department of King Edward Medical University/Mayo Hospital, Lahore, from January 2014 to January 2016. All patients who were presented in nephrology outpatients department and with the indication of dialysis were included in study. Patients who refused dialysis, and with acute kidney failure were excluded from the study. Proforma was designed for demographics, vital signs, volume status, and laboratory data (hemoglobin, urea, creatinine, albumin, bicarbonate etc.) of all the patients. On the basis of referral, patients were divided into two groups, i.e. early referral and late referral. Early referrals were those patients who were referred to a nephrologist more than three months before dialysis initiation. Late referrals were those patients who were referred to a nephrologist less than three months before dialysis initiation. Patients were followed up at one, three, six, and 12 months for outcome, i.e. still on dialysis or died. One hundred and seventy-six patients were enrolled in the study, and 141 were followed up to one year. Seventy- two (51.1%) patients were male, 69 (48.9%) were female and most (n=69, 48.9%) were in the middle age group. Major causes of end-stage renal disease (ESRD) were hypertension 70 (49.6%) and diabetes mellitus 66 (46.8%). Seventy-six (53.9%) patients were in fluid overload and acidotic (n=123, 87.2%). Twenty-seven (19.1%) patients were referred early and 114 (80.9%) were referred late. Overall mortality was 78 (55.3%) at one year. Factors affecting mortality were financial status and metabolic acidosis, but not referral. Temporary access for hemodialysis has 1.38 times more risk for mortality than the patients with permanent access. There is no difference on the outcome of dialysis patients on the basis referral to nephrologist. Factors affecting overall mortality in both

Principles of complementary medicine in terms of a suggested scientific basis.

PubMed

Popp, Fritz-Albert

2008-05-01

In order to create a scientific basis of complementary medicine it is certainly necessary to add a more non-local approach to the molecular substance of orthodox "life-sciences". It should be able to explain strange phenomena like healing by homeopathy or acupuncture. A possible frame concerns oscillatory electromagnetic interactions as regulatory and - in case of disease--deregulatory impulses of the organisms. These couplings are found, for instance, in biological rhythms, external rhythmical influences (sun exposure, atmospheric disturbances), and vibrations of the body over a huge range of frequencies. One basic example is biophotons and "delayed luminescence".

Five year follow-up after a first booster vaccination against tick-borne encephalitis following different primary vaccination schedules demonstrates long-term antibody persistence and safety.

PubMed

Beran, Jiří; Xie, Fang; Zent, Olaf

2014-07-23

Long-term vaccination programs are recommended for individuals living in regions endemic for tick-borne encephalitis (TBE). Current recommendations suggest a first booster vaccine be administered 3 years after a conventional regimen or 12-18 months after a rapid regimen. However, the research supporting subsequent booster intervals is limited. The aim of this study was thus to evaluate the long-term persistence of TBE antibodies in adults and adolescents after a first booster dose with Encepur(®). A total of 323 subjects aged 15 years and over, who had received one of four different primary TBE vaccination series in a parent study, participated in this follow-up Phase IV trial. Immunogenicity and safety were assessed for up to five years after a first booster dose, which was administered three years after completion of the primary series. One subset of subjects was excluded from the booster vaccination since they had already received their booster prior to enrollment. For comparison, immune responses were still recorded for these subjects on Day 0 and on an annual basis until Year 5, but safety information was not collected. Following a booster vaccination, high antibody titers were recorded in all groups throughout the study. Neutralization test (NT) titers of ≥ 10 were noted in at least 94% of subjects at every time point post-booster (on Day 21 and through Years 1-5). These results demonstrated that a first booster vaccination following any primary immunization schedule results in high and long-lasting (>5 years) immune responses. These data lend support to the current belief that subsequent TBE booster intervals could be extended from the current recommendation. NCT00387634. Copyright © 2014 Elsevier Ltd.

Policy Design of Multi-Year Crop Insurance Contracts with Partial Payments

PubMed Central

Chen, Ying-Erh; Goodwin, Barry K.

2015-01-01

Current crop insurance is designed to mitigate monetary fluctuations resulting from yield losses for a specific year. However, yield realization tendency can vary from year to year and may depend on the correlation of yield realizations across years. When the current single-year Yield Protection (YP) and Area Risk Protection Insurance (ARPI) contracts are extended to multiple periods, actuarially fair premium rate is expected to decrease as poor yield realizations in a year can be offset by another year’s better yield realizations. In this study, we first use simulations to demonstrate how significant premium savings are possible when coverage is based on the sum of yields across years rather than on a year-by-year basis. We then describe the design of a multi-year framework of crop insurance and model the insurance using a copula approach. Insurance terms are extended to more than a year and the premium, liability, and indemnity are determined by a multi-year term. Moreover, partial payment is provided at the end of each term to offset the possibility of significant loss in a single term. County-level data obtained from the U.S. Department of Agriculture are used to demonstrate the implementations of the proposed multi-year crop insurance. The proposed multi-year plan would benefit farmers by offering insurance guarantees across years for significantly lower costs. PMID:26695074

Quasi Sturmian basis for the two-electon continuum

NASA Astrophysics Data System (ADS)

Zaytsev, A. S.; Ancarani, L. U.; Zaytsev, S. A.

2016-02-01

A new type of basis functions is proposed to describe a two-electron continuum which arises as a final state in electron-impact ionization and double photoionization of atomic systems. We name these functions, which are calculated in terms of the recently introduced quasi Sturmian functions, Convoluted Quasi Sturmian functions (CQS); by construction, they look asymptotically like a six-dimensional spherical wave. The driven equation describing an ( e, 3 e) process on helium in the framework of the Temkin-Poet model is solved numerically in the entire space (rather than in a finite region of space) using expansions on CQS basis functions. We show that quite rapid convergence of the solution expansion can be achieved by multiplying the basis functions by the logarithmic phase factor corresponding to the Coulomb electron-electron interaction.

This study aimed to determine if beneficial effects of individualized feedback of fracture risk on osteoporosis preventive behaviors and bone mineral density observed in a 2-year trial were sustained long-term. This was a 10-year follow-up of a 2-year RCT in 470 premenopausal women aged 25-44 years, who were randomized to one of two educational interventions (the Osteoporosis Prevention and Self-Management Course [OPSMC] or an osteoporosis information leaflet) and received tailored feedback of their relative risk of fracture in later life (high versus normal risk groups). Bone mineral density of lumbar spine and femoral neck were measured by dual-energy X-ray absorptiometry. Physical activity, dietary calcium intake, calcium and vitamin D supplements, and smoking status were measured by questionnaires. From 2 to 12 years, the high-risk group had a smaller decrease in femoral neck bone mineral density (β=0.023, 95% CI=0.005, 0.041 g/cm 2 ) but similar lumbar spine bone mineral density change as the normal-risk group. They were more likely to use calcium (relative risk=1.66, 95% CI=1.22, 2.24) and vitamin D supplements (1.99, 95% CI=1.27, 3.11). The OPSMC had no effects on bone mineral density change. Both high-risk (versus normal-risk) and the OPSMC groups (versus leaflet) had a more favorable pattern of smoking behavior change (relative risk=1.85, 95% CI=0.70, 4.89 and relative risk=2.27, 95% CI=0.86, 6.01 for smoking cessation; relative risk=0.33, 95% CI=0.13, 0.80 and relative risk=0.28, 95% CI=0.10, 0.79 for commenced or persistent smoking). Feedback of high fracture risk to younger women was associated with long-term improvements in osteoporosis preventive behaviors and attenuated femoral neck bone mineral density loss. Therefore, this could be considered as a strategy to prevent osteoporosis. Australian New Zealand Clinical Trials Registry (ANZCTR) NCT00273260.

Health and re-employment in a two year follow up of long term unemployed.

PubMed

Claussen, B; Bjørndal, A; Hjort, P F

1993-02-01

The aim was to examine re-employment and changes in health during a two year follow up of a representative sample of long term unemployed. This was a cross sectional study and a two year follow up. Health was measured by psychometric testing, Hopkins symptom checklist, General health questionnaire, and medical examination. Health related selection to continuous unemployment and recovery by re-employment was estimated by logistic regression with covariances deduced from the labour market theories of human capital and segmented labour market. Four municipalities in Greenland, southern Norway. Participants were a random sample of 17 to 63 year old people registered as unemployed for more than 12 weeks. In the cross sectional study, the prevalence of depression, anxiety, and somatic illness was from four to 10 times higher than in a control group of employed people. In the follow up study, there was considerable health related selection to re-employment. A psychiatric diagnosis was associated with a 70% reduction in chances of obtaining a job. Normal performance on psychometric testing showed a two to three times increased chance of re-employment. Recovery of health following re-employment was less than expected from previous studies. Health related selection to long term unemployment seems to explain a substantial part of the excess mental morbidity among unemployed people. An increased proportion of the long term unemployed will be vocationally handicapped as years pass, putting a heavy burden on social services.

Although long-term results of sleeve gastrectomy (LSG) remain scarce in the literature, its popularity as a stand-alone procedure has accounted for a global increase in LSG performance. In this retrospective study, the authors present 5 to 8-year follow-up results in terms of weight loss, failure/revision rate, and comorbidity resolution from a single center. A prospectively maintained database was reviewed for patients who underwent LSG between 2007 and 2010. Data analysis on weight loss, comorbid conditions, revision surgery, and mortality was conducted. Median percentage excess BMI loss (%EBMIL) was 59.0, and 53.9 %, and median percentage total weight loss (%TWL) was 25.1, and 22.9 % at 5 and 8 years, respectively. Revision to gastric bypass due to insufficient weight loss or gastroesophageal reflux disease (GERD) was performed in 42 patients (15.2 %). Resolution of comorbid condition was achieved in 91 % of patients with obstructive sleep apnea syndrome (OSAS), 68 % of patients with type 2 diabetes (T2DM), 53 % of patients with hypertension, and 25 % of patients with dyslipedemia. Loss to follow-up rate was 45 % at 5 years, 28 % at 6 years, 23 % at 7 years, and 13 % at 8 years. This study adds to the currently available data confirming the LSG to be a safe and effective procedure at long term. Data from high-volume studies are needed to establish the definite role of the LSG in the spectrum of bariatric procedures.

Omalizumab has demonstrated therapeutic benefits both in controlled clinical trials and real-life studies. However, research concerning the long-term effects and tolerability of omalizumab is needed. The main objective of this study was to evaluate the effectiveness and tolerability of treatment with omalizumab for up to 5 years. A multicenter, retrospective, chart-based study was carried out to compare documented exacerbations, hospitalizations, systemic steroid requirement, FEV1, and asthma control test (ACT) results during 1 year prior to omalizumab treatment versus at 1, 3, and 5 years of treatment. Adverse events and reasons for discontinuation were also recorded at each time point. Four hundred and sixty-five patients were enrolled in the study. Outcome variables had improved after the 1st year and were sustained after the 3rd and 5th years of treatment with omalizumab. Omalizumab treatment reduced the asthma exacerbation rate by 71.3% (p < 0.001) at 1 year, 64.3% (p < 0.001) at 3 years, and 54.8% (p = 0.002) at 5 years. The hospitalization rate also decreased; by the 5th year of the treatment no patients were hospitalized. ACT results had also improved significantly: 12 (p < 0.001) at 1 year, 12 (p < 0.001) at 3 years, and 12 (p = 0.002) at 5 years. Overall, 12.7% of patients reported adverse events (most of these were mild-to-moderate) and the overall dropout rate was 9.0%. Omalizumab had a significant effect on asthma outcomes and this effect was maintained over 5 years. The drug was found to be generally safe and treatment compliance was good. © 2018 S.

This study aimed to analyze long-term survival and functional outcomes after truncus arteriosus repair in a single institution with more than 40 years of follow-up. Medical records were analyzed retrospectively in 52 patients who underwent the Rastelli procedure for truncus arteriosus repair between 1974 and 2002. Thirty-five patients survived the initial repair. The median age at the initial operation was 2.8 months (range, 0.1-123 months) and the body weight was 3.9 kg (range, 1.6 to 15.0 kg). The median age at follow-up was 23.6 years (range, 12.4 to 44.5 years). The median follow-up duration was 23.4 years (range, 12.3 to 40.7 years). The actuarial survival rate was 97% at 10 years and 93% at both 20 years and 40 years after the initial operation. At follow-up, most patients were in New York Heart Association (NYHA) functional classes I (73%) and II (24%). Thirty-six percent of patients had full-time jobs, 40% were students, and 21% were unemployed. Most patients (97%) had undergone conduit reoperations. Freedom from reoperation for right ventricular (RV) outflow and pulmonary artery (PA) stenosis was 59% at 5 years, 28% at 10 years, and 3% at 20 years after the initial operation. Freedom from catheter interventions for RV outflow and PA stenosis was 59% at 5 years, 47% at 10 years, and 38% at 20 years after the initial operation. Freedom from truncal valve replacement was 88% at 5 years, 85% at 10 years, and 70% at 20 years after the initial operation. In this single-center retrospective study, with long-term follow-up after repair of truncus arteriosus, long-term survival and functional outcomes were acceptable, despite the requirement for reoperation and multiple catheter interventions for RV outflow and PA stenosis in almost all patients, and the frequent requirement for late truncal valve operations. © 2016 The Authors.

There is almost no data describing the long-term functional outcome of patients after penetrating cardiac injury. A retrospective study at a Level I trauma center from 2000 to 2009. Sixty-three patients had penetrating cardiac injuries from 28 stabbings and 35 gunshots. Men comprised 89% (56) of the patients. Overall, there were 21 survivors (33%) and 42 died in the emergency room or perioperative period. The mean age did not significantly differ between survivors (36 years ± 12 years) compared with those who died (30 years ± 11 years; p=0.07). There was an increased chance of survival after being stabbed compared with being shot (17 patients vs. 4 patients; odds ratio=12; p=0.002). Thirteen (62%) had injuries to the right ventricle only. Three patients died during follow-up: one from lung cancer and two other patients died from myocardial infarctions, one 9 years later at the age of 45 years and the other 8 years later at the age of 55 years. The survivors had functional follow-up evaluations from 2 months to 114 months (median, 71; interquartile range, 34-92 months) and echocardiographic follow-up from 2 months to 107 months (median, 64; interquartile range, 31-84 months) after their injuries. Functionally, all patients were in NYHA class 1 status, except one patient in class II who was 54 years old and had a mild exertional limitation. The previously injured area could only be identified by echocardiogram in one patient who had a patch repair of a ventricular septal defect (VSD). The mean ejection fraction improved over time from a mean of 51% ± 8% in the immediate postoperative period to 60% ± 9% after a mean follow-up of 59 months (p=0.01). After surgery, 43% of patients had a mild to moderate pericardial effusion; however, the long-term follow-up studies showed that all these had resolved. Wall motion abnormalities occurred in 33% of patients in the immediate postoperative period and, again, all these resolved during long-term follow-up. Patients who

This longitudinal study examined the contribution of infants' temperament, mother's attachment style, and perceived grandmother's support following delivery, to the psychological mental health and marital adaptation of first time and non-first time Israeli mothers of pre-term (n = 70) and full-term (n = 78) twins, a year later. We collected data for the current study over 2 years (2003-2004). The findings suggested that the extent of mothers' personal and familial stress and their internal resource of attachment style played a crucial role in their mental health and marital adaptation. The external resource of grandmother's support contributed directly to the mothers' marital adaptation, whereas it contributed to their mental health only when infant's temperament was perceived to be difficult. Interestingly, the association between stress and adaptation was stronger among mothers of full-term twins than mothers of pre-term twins. Theoretical and clinical implications are discussed.

STUDY OBJECTIVE--The aim was to examine re-employment and changes in health during a two year follow up of a representative sample of long term unemployed. DESIGN--This was a cross sectional study and a two year follow up. Health was measured by psychometric testing, Hopkins symptom checklist, General health questionnaire, and medical examination. Health related selection to continuous unemployment and recovery by re-employment was estimated by logistic regression with covariances deduced from the labour market theories of human capital and segmented labour market. SETTING--Four municipalities in Greenland, southern Norway. SUBJECTS--Participants were a random sample of 17 to 63 year old people registered as unemployed for more than 12 weeks. MAIN RESULTS--In the cross sectional study, the prevalence of depression, anxiety, and somatic illness was from four to 10 times higher than in a control group of employed people. In the follow up study, there was considerable health related selection to re-employment. A psychiatric diagnosis was associated with a 70% reduction in chances of obtaining a job. Normal performance on psychometric testing showed a two to three times increased chance of re-employment. Recovery of health following re-employment was less than expected from previous studies. CONCLUSIONS--Health related selection to long term unemployment seems to explain a substantial part of the excess mental morbidity among unemployed people. An increased proportion of the long term unemployed will be vocationally handicapped as years pass, putting a heavy burden on social services. Images PMID:8436885

Long-term predictions using natural analogues

One of the unique and scientifically most challenging aspects of nuclear waste isolation is the extrapolation of short-term laboratory data (hours to years) to the long time periods (10{sup 3}-10{sup 5} years) required by regulatory agencies for performance assessment. The direct validation of these extrapolations is not possible, but methods must be developed to demonstrate compliance with government regulations and to satisfy the lay public that there is a demonstrable and reasonable basis for accepting the long-term extrapolations. Natural systems (e.g., {open_quotes}natural analogues{close_quotes}) provide perhaps the only means of partial {open_quotes}validation,{close_quotes} as well as data that may be used directlymore » in the models that are used in the extrapolation. Natural systems provide data on very large spatial (nm to km) and temporal (10{sup 3}-10{sup 8} years) scales and in highly complex terranes in which unknown synergisms may affect radionuclide migration. This paper reviews the application (and most importantly, the limitations) of data from natural analogue systems to the {open_quotes}validation{close_quotes} of performance assessments.« less

Long-term (10 year) trends in the chemistry of urban streams

Weekly sampling of eight streams in the Baltimore metropolitan area has been carried out since 1998 as part of the NSF funded Baltimore urban Long-Term Ecological Research (BES LTER) project. The BES watersheds include 100% forested and agricultural catchments and developed watersheds ranging from very low-density (<1% impervious surface) suburban watersheds serviced by septic systems to more dense (> 40% impervious surface) urban watersheds. Stream discharge is continuously monitored at these sites by the U.S. Geological Survey (USGS). Stream samples are collected weekly regardless of flow conditions (no bias towards storm versus baseflow) and analyzed for nitrate, total nitrogen (N), phosphate, total phosphorus (P), chloride and sulfate. Ten-year analysis of the BES long-term study sites reveals several interesting spatial and temporal patterns. For N, the highest concentrations were found in the agricultural and suburban watersheds, followed by the urban sites, and finally by the forested site. Organic N was most important as a proportion of total N in the urban and forested sites. Spatial patterns in P were more complex, with urban, suburban and agricultural sites having the highest values. Over the ten year record, many sites showed significant changes in N concentrations, but few sites showed consistent patterns in P. The patterns in N were quite variable however, with some sites showing striking increases, while others showed striking decreases. Most (7 of 8) sites showed a decrease in the proportion of organic N, the trend was significant at 4 of the sites. There were few trends in the proportion of organic P. Discharge was a significant driver of variation in N and P export at some (mostly smaller watersheds) sites, for some solutes, but was not an overwhelmingly important driver of temporal variation. Key factors driving long-term patterns include climate variation and efforts to improve urban stream water quality by municipal authorities.

To assess associations between white matter properties and pre-reading skills (phonological awareness and receptive and expressive language) in children born preterm and at term at the onset of reading acquisition. Six-year-old children born preterm (n=36; gestational age 22-32wks) and at term (n=43) underwent diffusion magnetic resonance imaging and behavioural assessments. Tracts were selected a priori based on findings from a study of 6-year-old children born at term: the left-hemisphere arcuate fasciculus and superior longitudinal fasciculus, and right-hemisphere uncinate fasciculus. Using linear regression, we assessed associations between fractional anisotropy of tracts and phonological awareness and receptive and expressive language scores. We investigated whether associations were moderated by prematurity. Fractional anisotropy of the left-hemisphere arcuate fasciculus contributed unique variance to phonological awareness across birth groups. The association between fractional anisotropy of the right-hemisphere uncinate fasciculus and receptive and expressive language was significantly moderated by prematurity. A left-hemisphere tract was associated with phonological awareness in both birth groups. A right-hemisphere tract was associated with language only in the term group, suggesting that expressive and receptive language is mediated by different white matter pathways in 6-year-old children born preterm. These findings provide novel insights into similarities and differences of the neurobiology of pre-reading skills between children born preterm and at term at reading onset. White matter properties and pre-reading abilities were associated in children born preterm at the onset of reading. The neurobiology of phonological awareness was similar in children born preterm versus children born at term at 6 years. The neurobiology of language was different in children born preterm versus children born at term at 6 years. © 2018 Mac Keith Press.

The number of hip fractures is rising as life expectancy increases. As such, the number of centenarians sustaining these fractures is also increasing. The purpose of this study was to determine whether patients who are ≥100 years old and sustain a hip fracture fare worse in the hospital than those who are younger. Using a large database, the New York Statewide Planning and Research Cooperative System (SPARCS), we identified patients who were ≥65 years old and had been treated for a hip fracture over a 12-year period. Data on demographics, comorbidities, and treatment were collected. Three cohorts were established: patients who were 65 to 80 years old, 81 to 99 years old, and ≥100 years old (centenarians). Outcome measures included hospital length of stay, estimated total costs, and in-hospital mortality rates. A total of 168,087 patients with a hip fracture were identified, and 1,150 (0.7%) of them had sustained the fracture when they were ≥100 years old. Centenarians incurred costs and had lengths of stay that were similar to those of younger patients. Despite the similarities, centenarians were found to have a significantly higher in-hospital mortality rate than the younger populations (7.4% compared with 4.4% for those 81 to 99 years old and 2.6% for those 65 to 80 years old; p < 0.01). Male sex and an increasing number of medical comorbidities were found to predict in-hospital mortality for centenarians sustaining extracapsular hip fractures. No significant predictors of in-hospital mortality were identified for centenarians who sustained femoral neck fractures. An increased time to surgery did not influence the odds of in-hospital mortality. Centenarians had increased in-hospital mortality, but the remaining short-term outcomes were comparable with those for the younger cohorts with similar fracture patterns. For this extremely elderly population, time to surgery does not appear to affect short-term mortality rates, suggesting a potential benefit to

The term subluxation has come to have different meanings for different health care professions in the United States for over the past century. This controversy has resulted in some contention both internal and external to the chiropractic profession. Some current factions within the chiropractic profession hold the term subluxation to be synonymous with the identity of chiropractic itself; however, this term was not solely used by chiropractic during its formative years. The purpose of this article is to look at uses of the term by various professions (osteopathy, medicine, and chiropractic) at the turn of the century, a time in which the chiropractic profession was developing.

Creating Long Term Income Streams for the 100 Year Starship Study Initiative

NASA Astrophysics Data System (ADS)

Sylvester, A. J.

Development and execution of long term research projects are very dependent on a consistent application of funding to maximize the potential for success. The business structure for the 100 Year Starship Study project should allow for multiple income streams to cover the expenses of the research objectives. The following examples illustrate the range of potential avenues: 1) affiliation with a charitable foundation for creating a donation program to fund a long term endowment for research, 2) application for grants to fund initial research projects and establish the core expertise of the research entity, 3) development of intellectual property which can then be licensed for additional revenue, 4) creation of spinout companies with equity positions retained by the lab for funding the endowment, and 5) funded research which is dual use for the technology goals of the interstellar flight research objectives. With the establishment of a diversified stream of funding options, then the endowment can be funded at a level to permit dedicated research on the interstellar flight topics. This paper will focus on the strategy of creating spinout companies to create income streams which would fund the endowment of the 100 Year Starship Study effort. This technique is widely used by universities seeking to commercially develop and market technologies developed by university researchers. An approach will be outlined for applying this technique to potentially marketable technologies generated as a part of the 100 Year Starship Study effort.

Hailstorms are natural phenomena of local or regional significance causing great material damage in present time, similarly as it was in the past. In Moravia (eastern part of the Czech Republic), systematic meteorological observations started generally in the latter half of the 19th century. Therefore, it is necessary to search for other sources of information in order to create long-term series of hailstorms. Documentary evidence is used in this study to extend the hailstorm information before the period of systematic observations and to complement existing systematic data. It allowed to compile a long-term series of summer half-year hailstorms in South Moravia using various types of documentary evidence (out of them taxation records, family archives, chronicles and newspapers are the most important) and systematic meteorological observations in the station network. Although available hailstorm data cover the 1435-2015 period, incomplete documentary evidence allows reasonable analysis of fluctuations in hailstorm frequency only since the 18th century (the frequency of hailstorms increases with the number of surviving documents). The long-term series compiled from documentary data and systematic meteorological observations is used to identify periods of lower and higher hailstorm frequency. The best temporal coverage of summer half-year hailstorm days in South Moravia starts in 1925 with a general decreasing trend of -0.05 days per 10 years up to 2015, more evident after 1961 (-1.4 days per 10 years). Existing data may also be used for the study of spatial hailstorm variability which is demonstrated on four particularly damaging hailstorms (on 20 June 1848, 1 July 1902, 10 July 1902 and 19 July 1903). Finally, uncertainties in the hailstorm chronology are discussed and differences related to various aspects of hailstorms detected from documentary and meteorological data in three 40 year periods are analysed. Despite some bias in hailstorm data, South

Advanced Test Reactor Safety Basis Upgrade Lessons Learned Relative to Design Basis Verification and Safety Basis Management

DOE Office of Scientific and Technical Information (OSTI.GOV)

G. L. Sharp; R. T. McCracken

The Advanced Test Reactor (ATR) is a pressurized light-water reactor with a design thermal power of 250 MW. The principal function of the ATR is to provide a high neutron flux for testing reactor fuels and other materials. The reactor also provides other irradiation services such as radioisotope production. The ATR and its support facilities are located at the Test Reactor Area of the Idaho National Engineering and Environmental Laboratory (INEEL). An audit conducted by the Department of Energy's Office of Independent Oversight and Performance Assurance (DOE OA) raised concerns that design conditions at the ATR were not adequately analyzedmore » in the safety analysis and that legacy design basis management practices had the potential to further impact safe operation of the facility.1 The concerns identified by the audit team, and issues raised during additional reviews performed by ATR safety analysts, were evaluated through the unreviewed safety question process resulting in shutdown of the ATR for more than three months while these concerns were resolved. Past management of the ATR safety basis, relative to facility design basis management and change control, led to concerns that discrepancies in the safety basis may have developed. Although not required by DOE orders or regulations, not performing design basis verification in conjunction with development of the 10 CFR 830 Subpart B upgraded safety basis allowed these potential weaknesses to be carried forward. Configuration management and a clear definition of the existing facility design basis have a direct relation to developing and maintaining a high quality safety basis which properly identifies and mitigates all hazards and postulated accident conditions. These relations and the impact of past safety basis management practices have been reviewed in order to identify lessons learned from the safety basis upgrade process and appropriate actions to resolve possible concerns with respect to the current ATR

100-Year flood–it's all about chance

USGS Publications Warehouse

Holmes, Robert R.; Dinicola, Karen

2010-01-01

In the 1960's, the United States government decided to use the 1-percent annual exceedance probability (AEP) flood as the basis for the National Flood Insurance Program. The 1-percent AEP flood was thought to be a fair balance between protecting the public and overly stringent regulation. Because the 1-percent AEP flood has a 1 in 100 chance of being equaled or exceeded in any 1 year, and it has an average recurrence interval of 100 years, it often is referred to as the '100-year flood'. The term '100-year flood' is part of the national lexicon, but is often a source of confusion by those not familiar with flood science and statistics. This poster is an attempt to explain the concept, probabilistic nature, and inherent uncertainties of the '100-year flood' to the layman.

The Mind and Brain of Short-Term Memory

2014-01-01

The past 10 years have brought near-revolutionary changes in psychological theories about short-term memory, with similarly great advances in the neurosciences. Here, we critically examine the major psychological theories (the “mind”) of short-term memory and how they relate to evidence about underlying brain mechanisms. We focus on three features that must be addressed by any satisfactory theory of short-term memory. First, we examine the evidence for the architecture of short-term memory, with special attention to questions of capacity and how—or whether—short-term memory can be separated from long-term memory. Second, we ask how the components of that architecture enact processes of encoding, maintenance, and retrieval. Third, we describe the debate over the reason about forgetting from short-term memory, whether interference or decay is the cause. We close with a conceptual model tracing the representation of a single item through a short-term memory task, describing the biological mechanisms that might support psychological processes on a moment-by-moment basis as an item is encoded, maintained over a delay with some forgetting, and ultimately retrieved.

Children born at term with low birth weight (LBW) are regarded growth restricted and are at particular risk of adverse health outcomes requiring a high degree of parental participation in the day-to-day care. This study examined whether their increased risk of special health care needs compared to other children may influence mothers' opportunities for participation in the labor market at different times after delivery. Data from 32,938 participants in the population-based Norwegian Mother and Child Cohort Study with singleton children born at term in 2004-2006 were linked to national registers in order to investigate the mothers' employment status when their children were 1-3 years in 2007 and 4-6 years in 2010. Children weighing less than two standard deviations below the gender-specific mean were defined as LBW children. Although not significantly different from mothers of children in the normal weight range, mothers of LBW children had the overall highest level of non-employment when the children were 1-3 years. At child age 4-6 years on the other hand, LBW was associated with an increased risk of non-employment (RR 1.39: 95 % CI 1.11-1.75) also after adjustment for factors associated with employment in general. In accordance with employment trends in the general population, our findings show that while mothers of normal birth weight children re-enter the labor market as their children grow older, mothers of LBW children born at term participate to a lesser extent in paid employment and remain at levels similar to those of mothers with younger children.

Long-term variation analysis of a tropical river's annual streamflow regime over a 50-year period

NASA Astrophysics Data System (ADS)

Seyam, Mohammed; Othman, Faridah

2015-07-01

Studying the long-term changes of streamflow is an important tool for enhancing water resource and river system planning, design, and management. The aim of this work is to identify the long-term variations in annual streamflow regime over a 50-year period from 1961 to 2010 in the Selangor River, which is one of the main tropical rivers in Malaysia. Initially, the data underwent preliminary independence, normality, and homogeneity testing using the Pearson correlation coefficient and Shapiro-Wilk and Pettitt's tests, respectively. The work includes a study and analysis of the changes through nine variables describing the annual streamflow and variations in the yearly duration of high and low streamflows. The analyses were conducted via two time scales: yearly and sub-periodic. The sub-periods were obtained by segmenting the 50 years into seven sub-periods by two techniques, namely the change-point test and direct method. Even though analysis revealed nearly negligible changes in mean annual flow over the study period, the maximum annual flow generally increased while the minimum annual flow significantly decreased with respect to time. It was also observed that the variables describing the dispersion in streamflow continually increased with respect to time. An obvious increase was detected in the yearly duration of danger level of streamflow, a slight increase was noted in the yearly duration of warning and alert levels, and a slight decrease in the yearly duration of low streamflow was found. The perceived changes validate the existence of long-term changes in annual streamflow regime, which increase the probability of floods and droughts occurring in future. In light of the results, attention should be drawn to developing water resource management and flood protection plans in order to avert the harmful effects potentially resulting from the expected changes in annual streamflow regime.

The structure of Leibniz superalgebras admitting a multiplicative basis

2016-12-01

In the literature, most of the descriptions of different classes of Leibniz superalgebras (L =L0bar ⊕L1bar , [ ṡ , ṡ ]) have been made by giving the multiplication table on the elements of a graded basis B ={vk } k ∈ K of L, in such a way that for any i , j ∈ K we have [vi ,vj ] =λi,j [vj ,vi ] ∈ Fvk for some k ∈ K, where F denotes the base field and λi,j ∈ F. In order to give a unifying viewpoint of all these classes of algebras we introduce the category of Leibniz superalgebras admitting a multiplicative basis and study its structure. We show that if a Leibniz superalgebra L =L0bar ⊕L1bar admits a multiplicative basis then it is the direct sum L =⨁αIα with any Iα =I α , 0 bar ⊕I α , 1 bar being a well described ideal of L admitting a multiplicative basis inherited from B. Also the B-simplicity of L is characterized in terms of J-connections.

Long-term studies of dopamine agonists.

PubMed

Hubble, Jean P

2002-02-26

Dopamine agonists have long been used as adjunctive therapy for the treatment of Parkinson's disease (PD). In more recent years these drugs have also been proved safe and effective as initial therapy in lieu of levodopa in the treatment of PD. Long-term levodopa therapy is associated with motor complications, including fluctuating response patterns and dyskinesia. By initially introducing a dopamine agonist as symptomatic drug therapy, it may be possible to postpone the use of levodopa and delay or prevent the development of motor complications. Recently, four clinical trials have explored this hypothesis by comparing the long-term response and side effects of levodopa with dopamine agonist therapy. The drugs studied have included ropinirole, pramipexole, cabergoline, and pergolide. In each of these projects, the occurrence of motor complications, such as wearing off and dyskinesia, was significantly less in the subjects assigned to initiation of therapy with a dopamine agonist. The addition of levodopa could be postponed by many months or even several years. Therefore, these long-term studies of dopamine agonists support the initiation of a dopamine agonist instead of levodopa in an effort to postpone levodopa-related motor complications. This therapeutic approach may be particularly appropriate in PD patients with a long treatment horizon on the basis of age and general good health. The extension phase of the long-term study comparing pramipexole with levodopa is ongoing, and follow-up information may help to establish the value of this treatment strategy.

2011-01-01

Proceeding from long-term data on the numbers of eggs of cod in ichthyoplankton, the total annual production of cod eggs at four main spawning grounds of the Baltic Sea was calculated. It was shown that the long-term fluctuations of cod egg production were positively related to the dynamics of the volume of waters coming to the Baltic Sea in years of the North Sea advections. It is suggested that this dependence was determined by a set of adaptations providing the extension of cod reproduction upon the improvement of the environment.

This study aimed at understanding the biochemical basis of internal browning disorders (IBDs) in 'Rocha' pear. For this purpose, the effects of storage under normal controlled atmosphere (CA) (3 kPa of O2 + 0.5 kPa of CO2) and IBD-inducing CA (1 kPa of O2 + 10 kPa of CO2) on the antioxidant and fermentative metabolisms and polyphenol oxidase (PPO) activity and phenolics concentration were studied. The higher IBD incidence in high CO2-stored fruits was positively correlated with fermentative metabolites and negatively with ascorbate and H2O2 concentrations, and it was linked to PPO activation. These results indicate that both the antioxidant and fermentative metabolisms are involved in the occurrence of IBD in 'Rocha' pear. From the integration of the biochemical and enzymatic data, a schematic model illustrating the effects of high CO2 and low O2 in 'Rocha' pears during long-term storage was constructed.

The Evidential Basis of Decision Making in Plant Disease Management.

PubMed

Hughes, Gareth

2017-08-04

The evidential basis for disease management decision making is provided by data relating to risk factors. The decision process involves an assessment of the evidence leading to taking (or refraining from) action on the basis of a prediction. The primary objective of the decision process is to identify-at the time the decision is made-the control action that provides the best predicted end-of-season outcome, calculated in terms of revenue or another appropriate metric. Data relating to disease risk factors may take a variety of forms (e.g., continuous, discrete, categorical) on measurement scales in a variety of units. Log 10 -likelihood ratios provide a principled basis for the accumulation of evidence based on such data and allow predictions to be made via Bayesian updating of prior probabilities.

We compared the ability of laparoscopic antireflux surgery (LARS) and esomeprazole to control esophageal acid exposure, over a 5-year period, in patients with chronic gastroesophageal reflux disease (GERD). We also studied whether intraesophageal and intragastric pH parameters off and on therapy were associated with long-term outcomes. We analyzed data from a prospective, randomized, open-label trial comparing the efficacy and safety of LARS vs esomeprazole (20 or 40 mg/d) over 5 years in patients with chronic GERD. Ambulatory intraesophageal and intragastric 24-hour pH monitoring data were compared between groups before LARS or the start of esomeprazole treatment, and 6 months and 5 years afterward. A secondary aim was to evaluate the association between baseline and 6-month pH parameters and esomeprazole dose escalation, reappearance of GERD symptoms, and treatment failure over 5 years in patients receiving LARS or esomeprazole. In the LARS group (n = 116), the median 24-hour esophageal acid exposure was 8.6% at baseline and 0.7% after 6 months and 5 years (P < .001 vs baseline). In the esomeprazole group (n = 151), the median 24-hour esophageal acid exposure was 8.8% at baseline, 2.1% after 6 months, and 1.9% after 5 years (P < .001, therapy vs baseline, and LARS vs esomeprazole). Gastric acidity was stable in both groups. Patients who required a dose increase to 40 mg/d had more severe supine reflux at baseline, and decreased esophageal acid exposure (P < .02) and gastric acidity after dose escalation. Esophageal and intragastric pH parameters, off and on therapy, did not predict long-term symptom breakthrough. In a prospective study of patients with chronic GERD, esophageal acid reflux was reduced greatly by LARS or esomeprazole therapy. However, patients receiving LARS had significantly greater reductions in 24-hour esophageal acid exposure after 6 months and 5 years. Esophageal and gastric pH, off and on therapy, did not predict long-term outcomes of

Matrix basis for plane and modal waves in a Timoshenko beam

2016-01-01

Plane waves and modal waves of the Timoshenko beam model are characterized in closed form by introducing robust matrix basis that behave according to the nature of frequency and wave or modal numbers. These new characterizations are given in terms of a finite number of coupling matrices and closed form generating scalar functions. Through Liouville’s technique, these latter are well behaved at critical or static situations. Eigenanalysis is formulated for exponential and modal waves. Modal waves are superposition of four plane waves, but there are plane waves that cannot be modal waves. Reflected and transmitted waves at an interface point are formulated in matrix terms, regardless of having a conservative or a dissipative situation. The matrix representation of modal waves is used in a crack problem for determining the reflected and transmitted matrices. Their euclidean norms are seen to be dominated by certain components at low and high frequencies. The matrix basis technique is also used with a non-local Timoshenko model and with the wave interaction with a boundary. The matrix basis allows to characterize reflected and transmitted waves in spectral and non-spectral form. PMID:28018668

The zygoma implant has been an effective option in the short-term management of the atrophic edentulous maxilla. To report on long-term outcomes in the rehabilitation of the atrophic maxilla using zygomatic (ZI) and regular implants (RI). 22 consecutive zygomatic patients in a maintenance program were included. Cumulative survival rate (CSR) of ZI, RI, prostheses, and complications were recorded during, at least, 10 years of loading. Implant mobility was tested using Periotest(®). Sinus health was radiographically and clinically assessed according to Lund-Mackay (L-M) score and Lanza and Kennedy survey, respectively. A satisfaction questionnaire and anatomical measurements were also performed. Patients received 22 prostheses, anchored on 172 implants. Forty-one were ZI. Three RI failed (10 years CSR = 97.71%). Two ZI were partly removed due to perimplant infection (10 years CSR = 95.12%). All patients maintained functional prostheses. One patient fractured framework twice. Loosening or fracturing screws happened in 11 patients. Seven patients fractured occlusal material. Four ZI abutments in two patients were disconnected because of uncomfortable prostheses. Alveolar height at the ZI head level on the right and left sides was 2.64 mm and 2.25 mm, respectively. Mean distance of ZI head center to ridge center, on the right and left sides was 4.54 mm and 5.67 mm, respectively. Mean Periotest values (PTv) of ZI were -4.375 PTv and -4.941 PTv before prostheses placement and after 10 years, respectively. Six patients experienced sinusitis 14-127 months postoperatively. 54.55% of the L-M scores did not present opacification (L-M = 0) in any sinus. Osteomeatal obstruction happened in eight patients (two bilateral). Two (9.09%) were diagnosed with sinusitis. Eighty-four percent reported satisfaction levels above 80%. 31.81% reported maximum satisfaction score (100%). The long-term rehabilitation of the severely atrophic maxillae using ZI is a predictable procedure. © 2012

Automated radial basis function neural network based image classification system for diabetic retinopathy detection in retinal images

NASA Astrophysics Data System (ADS)

Anitha, J.; Vijila, C. Kezi Selva; Hemanth, D. Jude

2010-02-01

Diabetic retinopathy (DR) is a chronic eye disease for which early detection is highly essential to avoid any fatal results. Image processing of retinal images emerge as a feasible tool for this early diagnosis. Digital image processing techniques involve image classification which is a significant technique to detect the abnormality in the eye. Various automated classification systems have been developed in the recent years but most of them lack high classification accuracy. Artificial neural networks are the widely preferred artificial intelligence technique since it yields superior results in terms of classification accuracy. In this work, Radial Basis function (RBF) neural network based bi-level classification system is proposed to differentiate abnormal DR Images and normal retinal images. The results are analyzed in terms of classification accuracy, sensitivity and specificity. A comparative analysis is performed with the results of the probabilistic classifier namely Bayesian classifier to show the superior nature of neural classifier. Experimental results show promising results for the neural classifier in terms of the performance measures.

Using a pruned, nondirect product basis in conjunction with the multi-configuration time-dependent Hartree (MCTDH) method

DOE Office of Scientific and Technical Information (OSTI.GOV)

Wodraszka, Robert, E-mail: Robert.Wodraszka@chem.queensu.ca; Carrington, Tucker, E-mail: Tucker.Carrington@queensu.ca

In this paper, we propose a pruned, nondirect product multi-configuration time dependent Hartree (MCTDH) method for solving the Schrödinger equation. MCTDH uses optimized 1D basis functions, called single particle functions, but the size of the standard direct product MCTDH basis scales exponentially with D, the number of coordinates. We compare the pruned approach to standard MCTDH calculations for basis sizes small enough that the latter are possible and demonstrate that pruning the basis reduces the CPU cost of computing vibrational energy levels of acetonitrile (D = 12) by more than two orders of magnitude. Using the pruned method, it ismore » possible to do calculations with larger bases, for which the cost of standard MCTDH calculations is prohibitive. Pruning the basis complicates the evaluation of matrix-vector products. In this paper, they are done term by term for a sum-of-products Hamiltonian. When no attempt is made to exploit the fact that matrices representing some of the factors of a term are identity matrices, one needs only to carefully constrain indices. In this paper, we develop new ideas that make it possible to further reduce the CPU time by exploiting identity matrices.« less

In a longitudinal cohort (prevention group, n=213, comparison group, n=163) of 10-year prospective follow-up we addressed efficacy of 5-year-long multifactor preventive intervention, conducted in a sample of population of 12 year old boys. Preventive intervention was carried out both at populational level and among persons with risk factors of development of cardiovascular diseases with the use of group, individual, and partly family approaches, and was directed at rationalization of nutrition, elevation of physical activity and prevention of harmful habits. During first 3 years of prevention we succeeded to achieve stable statistically significant lowering of mean levels of total cholesterol, low density lipoprotein cholesterol, triglycerides, and atherogeneity index, as well as to affect fatty component of body mass (skinfold thickness). Long term effect of 5-year long preventive intervention manifested as significantly lower level of systolic blood pressure, lower prevalence of low levels of high density lipoprotein cholesterol, smaller increment of low density lipoprotein cholesterol and index of atherogeneity in the prevention group. These results evidence that prevention of main factors of risk of development of cardiovascular diseases (obesity, arterial hypertension, disorders of lipid composition of the blood, and low physical activity) in child and adolescent age in the period of active growth and development is feasible, effective, safe and is able to lead to decrease of levels of these factors in adults, but should last uninterruptedly until formation of stable habits of healthy life style.

Long-term care: long-term care insurance--2005. End of Year Issue Brief.

As the "Baby Boom" generation approaches retirement, state and federal lawmakers are struggling to ensure that the nation's long-term care system will provide adequate services for the growing number of senior citizens. A 2003 Administration on Aging report predicted that the elderly population will double by 2030. Accordingly, policymakers must prepare for the impending squeeze on public health and Medicaid resources. Many consumers are exploring private long-term care insurance options as a means of preparing for the cost of eldercare. Yet, a lack of market uniformity has rendered the long-term care insurance industry somewhat difficult for consumers to decipher. In addition, senior care insurance is often costly, particularly for those over age 50.

Background The aim of this analysis is to describe the long-term changes in CD4 cell counts beyond 5 years of combination antiretroviral therapy (cART). If natural ageing leads to a long-term decline in the immune system via low-grade chronic immune activation/inflammation, then one might expect to see a greater or earlier decline in CD4 counts in older HIV-positive patients with increasing duration of cART. Methods Retrospective and prospective data were examined from long-term virologically stable HIV-positive adults from the Australian HIV Observational Database. We estimated mean CD4 cell counts changes following the completion of 5 years of cART using linear mixed models. Results A total of 37,916 CD4 measurements were observed for 892 patients over a combined total of 9,753 patient years. Older patients (>50 years) at cART initiation had estimated mean(95% confidence interval) change in CD4 counts by Year-5 CD4 count strata (<500, 501–750 and >750 cells/μL) of 14(7 to 21), 3(−5 to 11) and −6(−17 to 4) cells/μL/year. Of the CD4 cell count rates of change estimated, none were indicative of long-term declines in CD4 cell counts. Conclusions Our results suggest that duration of cART and increasing age does not result in decreasing mean changes in CD4 cell counts for long-term virologically suppressed patients. Indicating that level of immune recovery achieved during the first 5 years of treatment are sustained through long-term cART. PMID:23036045

Results of the first research of this kind on the 23-year long-term outcome in children born during the war in Vukovar are presented. This retrospective clinical study surveyed the potential 23-year long-term consequences and morbidity of children born between May 1, 1991 and November 19, 1991, during the siege and occupation of Vukovar. Data were obtained from women having delivered their babies in that period and from delivery protocols of the Department of Gynecology and Obstetrics, Vukovar County Hospital. According to the survey and the data collected, there were 9 (3.98%) preterm deliveries, 60 (81%) of the total of 77 subjects were breastfed, 14 (19%) were not breastfed, while three babies died in the postpartum period. However, the breastfeeding period was evidently shorter, as only 10 women breastfed for a period longer than 6 months, while the mean length of the breastfeeding period was 9.9 weeks, i.e. 2.5 months. Allergy-related illnesses and proneness to infections in childhood and preschool age were found in 27.3% and 16.9% of children, respectively, while two children developed diabetes type 1. One child had atopic diathesis, two started speaking after the age of two, one child started walking late (after 20 months) and started speaking after the age of two, one child had loud sound phobia, and one used to overreact and express anger in inconvenient situations, all of them being of female gender and born prematurely. Cognitive and attention disorders and stress reactions were found in 6.5% of the children. Regular elementary school education was completed by 74 (96%) children, while three (3.8%) children experienced failure at school due bad behavior, i.e. delinquency. At the age of 23, 34 (46%) children had developed bad habits, i.e. 33 of them smoked, 2 were addicted to alcohol, whereas one was addicted to both smoking and alcohol. Forty (54%) subjects did not use any harmful substances. Psychiatric disorders related to anxiety, depression or other

It is unclear whether long-term seizure outcomes in children are similar to those in adult epilepsy surgery patients. To determine 5-year outcomes and antiepilepsy drug (AED) use in pediatric epilepsy surgery patients from a single institution. The cohort consisted of children younger than 18 years of age whose 5-year outcome data would have been available by 2010. Comparisons were made between patients with and without 5-year data (n = 338), patients with 5-year data for seizure outcome (n = 257), and seizure-free patients on and off AEDs (n = 137). Five-year data were available from 76% of patients. More seizure-free patients with focal resections for hippocampal sclerosis and tumors lacked 5-year data compared with other cases. Of those with 5-year data, 53% were continuously seizure free, 18% had late seizure recurrence, 3% became seizure free after initial failure, and 25% were never seizure free. Patients were more likely to be continuously seizure free if their surgery was performed during the period 2001 to 2005 (68%) compared with surgery performed from 1996 to 2000 (61%), 1991 to 1995 (36%), and 1986 to 1990 (46%). More patients had 1 or fewer seizures per month in the late seizure recurrence (47%) compared with the not seizure-free group (20%). Four late deaths occurred in the not seizure-free group compared with 1 in the seizure-free group. Of patients who were continuously seizure free, 55% were not taking AEDs, and more cortical dysplasia patients (74%) had stopped taking AEDs compared with hemimegalencephaly patients (18%). In children, 5-year outcomes improved over 20 years of clinical experience. Our results are similar to those of adult epilepsy surgery patients despite mostly extratemporal and hemispheric operations for diverse developmental etiologies.

Cognitive and Guided Mastery Therapies for Panic Disorder with Agoraphobia: 18-Year Long-Term Outcome and Predictors of Long-Term Change.

2016-01-01

In this study, we wished to compare the long-term outcome of (medication-free) panic disorder with agoraphobia patients randomized to cognitive or guided mastery therapy. Thirty-one (67.4%) of 46 patients who had completed treatment were followed up about 18 years after end of treatment. In the combined sample and using intent-to-follow-up analyses, there were large within-group effect sizes of -1.79 and -1.63 on the primary interview-based and self-report outcome measures of avoidance of situations when alone, and 56.5% no longer had a panic disorder and/or agoraphobia diagnosis. No outcome differences between the two treatments emerged. Guided mastery was associated with greater beneficial changes in catastrophic beliefs and self-efficacy. For two of five outcome measures, more reduction in panic-related beliefs about physical and mental catastrophes from pre- to post-treatment predicted lower level of anxiety from post-treatment to 18-year follow-up when the effect of treatment changes in (a) self-efficacy and (b) anxiety was controlled. However, for one of the outcome measures, this effect attenuated with time. Copyright © 2014 John Wiley & Sons, Ltd. The results suggest that the very-long-term outcome of both cognitive therapy and guided mastery therapy for agoraphobia is positive. The results support the role of catastrophic beliefs as mediator of change. The pattern of results suggests that learning processes other than catastrophic beliefs may be important for long-term outcome as well. Copyright © 2014 John Wiley & Sons, Ltd.

Long-term results of transluminal angioplasty (TLA) of the prevertebral subclavian artery (PVSA) are not well known. The aim of this work was to present a retrospective analysis of a consecutive series of 81 TLAs of the PVSA, with a mean follow-up of approximately 7 years (82 months). From January 1984 to May 2007, 81 TLAs of PVSA were consecutively performed in 72 patients (64% men; median age = 56.7 years) to treat 71 tight stenoses and 10 occlusions. In 58 cases, TLA was carried out under local anesthesia (71.6%), 65 times by femoral approach, and 16 times by humeral approach. A percutaneous approach was used 72 times (89%). A stent was placed in 18 cases (22.2%). Immediate technical success rate was 93%. One transient monoplegia was noticed after TLA and four puncture complications were observed, which occurred significantly more frequently with percutaneous humeral approach (p = 0.024). A recurrent stenosis occurred 28 times (34.6%) and was symptomatic in three cases. With a mean 82-month follow-up (3-299 months), primary patency at 10 years was 85.2% and primary assisted patency was 92.6%. No restenosis occurred after the 25th month of the follow-up. No restenosis factor was statistically predictive. TLA of the PVSA is a mildly invasive and efficient treatment. Early restenoses are frequent but remain accessible to a new TLA with stable long-term results. Copyright © 2011 Annals of Vascular Surgery Inc. Published by Elsevier Inc. All rights reserved.

To compare school performance at age 5 years in children born at full term (39-41 weeks gestation) with those born at early term (37-38 weeks gestation), late preterm (34-36 weeks gestation), moderately preterm (32-33 weeks gestation) and very preterm (<32 weeks gestation). Population-based cohort (UK Millennium Cohort Study). Seven thousand six hundred and fifty children born in 2000-2001 and attending school in England in 2006. School performance was measured using the foundation stage profile (FSP), a statutory assessment by teachers at the end of the child's first school year. The FSP comprises 13 assessment scales (scored from 1 to 9). Children who achieve an average of 6 points per scale and at least 6 in certain scales are classified as 'reaching a good level of overall achievement'. Fifty-one per cent of full term children had not reached a good level of overall achievement; this proportion increased with prematurity (55% in early term, 59% in late preterm, 63% in moderately preterm and 66% in very preterm children). Compared with full term children, an elevated risk remained after adjustment, even in early term (adjusted RR 1.05, 95% 1.00 to 1.11) and late preterm children (adjusted RR 1.12, 95% CI 1.04 to 1.22). Similar effects were noted for 'not working securely' in mathematical development, physical development and creative development. The effects of late preterm and early term birth were small in comparison with other risk factors. Late preterm and early term birth are associated with an increased risk of poorer educational achievement at age 5 years.

The purpose of this study was to investigate the potential long-term association of motor skill proficiency at 6 years of age and self-reported physical activity (PA) at age 26. Direct motor performance data were collected in 1991 with a follow-up study occurring in 1996, and then indirect questionnaires (self-report) administered in 2001 and 2011. In 2011, 17 participants who were identified as either having high motor proficiency (HMP) or low motor proficiency (LMP) in 1991 completed a series of 4 questionnaires. Analyses were conducted to determine whether there were differences between groups for motor skill proficiency, PA, or sedentary behavior, and whether these outcomes were related across ages. Motor skill proficiency at age 6 was related to self-reported proficiency at age 16 (r = .77, p = .006), and self-reported proficiency between 16 and 26 years (r = .85, p = .001). Motor skill proficiency at age 6 was positively associated with leisure time PA at age 26 in females and participants in the HMP group. The results may provide preliminary evidence about the importance of how early motor skill proficiency relates to long-term PA. More research with larger sample sizes is needed to investigate the importance of motor skills over time.

Evaluation of the mathematical and economic basis for conversion processes in the LEAP energy-economy model

NASA Astrophysics Data System (ADS)

Oblow, E. M.

1982-10-01

An evaluation was made of the mathematical and economic basis for conversion processes in the Long-term Energy Analysis Program (LEAP) energy economy model. Conversion processes are the main modeling subunit in LEAP used to represent energy conversion industries and are supposedly based on the classical economic theory of the firm. Questions about uniqueness and existence of LEAP solutions and their relation to classical equilibrium economic theory prompted the study. An analysis of classical theory and LEAP model equations was made to determine their exact relationship. The conclusions drawn from this analysis were that LEAP theory is not consistent with the classical theory of the firm. Specifically, the capacity factor formalism used by LEAP does not support a classical interpretation in terms of a technological production function for energy conversion processes. The economic implications of this inconsistency are suboptimal process operation and short term negative profits in years where plant operation should be terminated. A new capacity factor formalism, which retains the behavioral features of the original model, is proposed to resolve these discrepancies.

2015-07-01

We prospectively examined evidence for the sustained effects of early intervention based on a follow-up study of 39 children with ASD who began participation in a randomized clinical trial testing the effectiveness of the Early Start Denver Model (ESDM) at age 18 to 30 months. The intervention, conducted at a high level of intensity in-home for 2 years, showed evidence of efficacy immediately posttreatment. This group of children was assessed at age 6 years, 2 years after the intervention ended, across multiple domains of functioning by clinicians naive to previous intervention group status. The ESDM group, on average, maintained gains made in early intervention during the 2-year follow-up period in overall intellectual ability, adaptive behavior, symptom severity, and challenging behavior. No group differences in core autism symptoms were found immediately posttreatment; however, 2 years later, the ESDM group demonstrated improved core autism symptoms and adaptive behavior as compared with the community-intervention-as-usual (COM) group. The 2 groups were not significantly different in terms of intellectual functioning at age 6 years. Both groups received equivalent intervention hours during the original study, but the ESDM group received fewer hours during the follow-up period. These results provide evidence that gains from early intensive intervention are maintained 2 years later. Notably, core autism symptoms improved in the ESDM group over the follow-up period relative to the COM group. This improvement occurred at the same time that the ESDM group received significantly fewer services.

Margin of Safety Definition and Examples Used in Safety Basis Documents and the USQ Process

DOE Office of Scientific and Technical Information (OSTI.GOV)

Beaulieu, R. A.

The Nuclear Safety Management final rule, 10 CFR 830, provides an undefined term, margin of safety (MOS). Safe harbors listed in 10 CFR 830, Table 2, such as DOE-STD-3009 use but do not define the term. This lack of definition has created the need for the definition. This paper provides a definition of MOS and documents examples of MOS as applied in a U.S. Department of Energy (DOE) approved safety basis for an existing nuclear facility. If we understand what MOS looks like regarding Technical Safety Requirements (TSR) parameters, then it helps us compare against other parameters that do notmore » involve a MOS. This paper also documents parameters that are not MOS. These criteria could be used to determine if an MOS exists in safety basis documents. This paper helps DOE, including the National Nuclear Security Administration (NNSA) and its contractors responsible for the safety basis improve safety basis documents and the unreviewed safety question (USQ) process with respect to MOS.« less

Literature has evidenced behavioral and socio-emotional problems in preterm children, as well as long-term difficulties to establish and maintain social relationships in preterm population. Several studies have shown relations between behavior and social reasoning abilities in typically developing children and adults. The present study aimed to investigate the social understanding and social reasoning abilities in preterm children aged between 5 and 7years in comparison to their full-term peers. A social resolution task (SRT) was used to assess abilities to judge, identify and reason about others' behavior in relation to conventional and moral rules knowledge. 102 preterm children and 88 full-term children were included in the study. Compared with their full-term peers, preterm children exhibited difficulties to understand and reason about inappropriate social behavior, particularly for situations related to the transgression of conventional rules. They used more irrelevant information and exhibited less social awareness when reasoning about the transgression of social rules. The only significant predictor for global SRT and social reasoning scores was the mental processing composite of the K-ABC, but the part of the variance of the SRT that could be explained by the general cognitive abilities was relatively small. Preterm children demonstrated poorer social knowledge and social reasoning abilities compared with full-term children at early school age. Improving such abilities may reduce behavioral difficulties and peer relationship problems often described in the preterm population. These findings emphasize the need to early identify children at risk for impaired social development. Copyright © 2016. Published by Elsevier Ireland Ltd.

TEC prediction models for 24 hours ahead have been developed from JOG2 GPS TEC data during 2016. Eleven month of TEC data were used as a training model of the radial basis function neural network (RBFNN) and 1 month of last data (December 2016) is used for the RBFNN model testing. The RBFNN inputs are the previous 24 hour TEC data and the minimum of Dst index during the previous 24 hours. Outputs of the model are 24 ahead TEC prediction. Comparison of model prediction show that the RBFNN model is able to predict the next 24 hours TEC is more accurate than the TEC GIM model.

Long Term Sequelae of Pediatric Craniopharyngioma – Literature Review and 20 Years of Experience

Cohen, Michal; Guger, Sharon; Hamilton, Jill

2011-01-01

Craniopharyngioma are rare histologically benign brain tumors that develop in the pituitary–hypothalamic area. They may invade nearby anatomical structures causing significant rates of neurological, neurocognitive, and endocrinological complications including remarkable hypothalamic damage. Information regarding long term implications of the tumors and treatment in the pediatric population is accumulating, and treatment goals appear to be changing accordingly. In this review we aim to present data regarding long term complications of craniopharyngioma in children and adolescents and our experience from a large tertiary center. Hypothalamic dysfunction was noted to be the most significant complication, adversely affecting quality of life in survivors. Obesity, fatigue, and sleep disorders are the most notable manifestations of this dysfunction, and treatment is extremely difficult. Changes in management in recent years show a potential for improved long term outcomes; we found a trend toward less aggressive surgical management and increasing use of adjuvant treatment, accompanied by a decrease in complication rates.

Data regarding costs of prostate cancer treatment are scarce. This study investigates how initial treatment choice affects short-term and long-term costs. This retrospective, longitudinal cohort study followed prostate-cancer cases diagnosed in 2000 for 5 years using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Men age≥66 years, in Medicare fee for service, diagnosed with clinically localized prostate cancer in 2000 while residing in a SEER region, were matched to noncancer controls using age, sex, race, region, comorbidity, and survival. On the basis of treatment received during the first 9 months postdiagnosis, patients were assigned to watchful waiting, radiation, hormonal therapy, hormonal+radiation, and surgery (may have received other treatments). Incremental costs for prostate cancer were the difference in costs for prostate cancer cases versus matched controls. Costs were divided into initial treatment (months -1 to 12), long-term (each 12 months thereafter), and total (months -1 to 60). Sensitivity analyses excluded the last 12 months of life. A total of 13,769 prostate-cancer cases were matched to 13,769 noncancer controls. Watchful waiting had the lowest initial treatment ($4270) and 5-year total costs ($9130). Initial treatment costs were highest for hormonal+radiation ($17,474) and surgery ($15,197). At $26,896, 5-year total costs were highest for hormonal therapy only followed by hormonal+radiation ($25,097) and surgery ($19,214). After excluding the last 12 months of life, total costs were highest for hormonal+radiation ($23,488) and hormonal therapy ($23,199). Patterns of costs vary widely based on initial treatment. These data can inform patients and clinicians considering treatment options and policy makers interested in patterns of costs. Copyright © 2010 American Cancer Society.

Examine the incremental impact of absenteeism and short-term disability associated with colorectal cancer (CRC). Absenteeism and short-term disability data were used for a case-control analysis of a healthy cohort (controls) compared with CRC patients (cases). Cases were matched to controls on the basis of age, sex, and region of residence. Multivariate regression models examined the costs of absenteeism and short-term disability, controlling for patient characteristics, prior medical costs, and patient general health. Compared with controls, CRC patients experience significantly higher short-term disability costs (mean, $45,716 vs $7367 [P < 0.0001]; median, $35,827 vs $7365 [P < 0.0001]), as well as significantly higher absenteeism costs (mean, $8841 vs $4596 [P < 0.0001]; median, $9971 vs $4795 [P < 0.0001]) in the 1 year after diagnosis of CRC. Colorectal cancer is associated with significant work-related productivity loss costs in the first year after diagnosis.

Ageing and long-term CD4 cell count trends in HIV-positive patients with 5 years or more combination antiretroviral therapy experience.

The aim of this study was to describe the long-term changes in CD4 cell counts beyond 5 years of combination antiretroviral therapy (cART). If natural ageing leads to a long-term decline in the immune system via low-grade chronic immune activation/inflammation, then one might expect to see a greater or earlier decline in CD4 counts in older HIV-positive patients with increasing duration of cART. Retrospective and prospective data were examined from long-term virologically stable HIV-positive adults from the Australian HIV Observational Database. We estimated mean CD4 cell count changes following the completion of 5 years of cART using linear mixed models. A total of 37 916 CD4 measurements were observed for 892 patients over a combined total of 9753 patient-years. Older patients (> 50 years old) at cART initiation had estimated mean (95% confidence interval) changes in CD4 counts by year-5 CD4 count strata (< 500, 500-750 and > 750 cells/μL) of 14 (7 to 21), 3 (-5 to 11) and -6 (-17 to 4) cells/μL/year. Of the CD4 cell count rates of change estimated, none were indicative of long-term declines in CD4 cell counts. Our results suggest that duration of cART and increasing age do not result in decreasing mean changes in CD4 cell counts for long-term virologically suppressed patients, indicating that the level of immune recovery achieved during the first 5 years of treatment is sustained through long-term cART. © 2012 British HIV Association.

A large proportion of the oldest old and centenarians live in long-term care facilities. Although there may be distinct care patterns in centenarians compared with other cohorts of oldest old, the exact development concerning prevalence, length of stay, and factors that are associated with long-term care status in the last years before death is unknown. Longitudinal analyses of health insurance data across 6 years before death. In all, 1398 institutionalized and noninstitutionalized oldest old [deceased at 80-89 (octogenarians), 90-99 (nonagenarians), or over 100 years of age (centenarians)] from Germany were included. Long-term care status and transition from home care into long-term care over 6 years (34,740 person-quarters). Dementia, musculoskeletal diseases, multimorbidity, hospital admission, gender, and age at death were derived from administrative data and analyzed using binary generalized estimating equations. Although the initial level of long-term care (6 years before death) was higher among centenarians (65.1% vs 53.6% in nonagenarians; 36.2% in octogenarians), the rate of increase was stronger in the younger cohorts. Distinguishing between long-term care escapers, delayers, and survivors, the proportion of those who escaped, delayed, or survived the entire 6 years of observation in long-term care was 33.4%/40.4%/26.2% in centenarians, 45.0%/45.1%/9.9% in nonagenarians, and 62.7%/33.7%/3.6% in octogenarians. Age, hospital admissions, and dementia were positively associated with being in long-term care, whereas musculoskeletal disorders were negatively associated with long-term care. The association with dementia was significantly weaker in centenarians. For centenarians, although they are more often in long-term care, the transition rate to long-term care progressed more slowly than the rates of the younger comparison cohorts of oldest old. The high proportion of long stays of centenarians in long-term care facilities require different concepts of

Life expectancy has increased for newly diagnosed HIV patients since the inception of combination antiretroviral treatment (cART), but there remains a need to better understand the characteristics of long-term survival in HIV-positive patients. We examined long-term survival in HIV-positive patients receiving cART in the Australian HIV Observational Database (AHOD), to describe changes in mortality compared to the general population and to develop longer-term survival models. Data were examined from 2,675 HIV-positive participants in AHOD who started cART. Standardised mortality ratios (SMR) were calculated by age, sex and calendar year across prognostic characteristics using Australian Bureau of Statistics national data as reference. SMRs were examined by years of duration of cART by CD4 and similarly by viral load. Survival was analysed using Cox-proportional hazards and parametric survival models. The overall SMR for all-cause mortality was 3.5 (95% CI: 3.0-4.0). SMRs by CD4 count were 8.6 (95% CI: 7.2-10.2) for CD4<350 cells/µl; 2.1 (95% CI: 1.5-2.9) for CD4 = 350-499 cells/µl; and 1.5 (95% CI: 1.1-2.0) for CD4≥500 cells/µl. SMRs for patients with CD4 counts <350 cells/µL were much higher than for patients with higher CD4 counts across all durations of cART. SMRs for patients with viral loads greater than 400 copies/ml were much higher across all durations of cART. Multivariate models demonstrated improved survival associated with increased recent CD4, reduced recent viral load, younger patients, absence of HBVsAg-positive ever, year of HIV diagnosis and incidence of ADI. Parametric models showed a fairly constant mortality risk by year of cART up to 15 years of treatment. Observed mortality remained fairly constant by duration of cART and was modelled accurately by accepted prognostic factors. These rates did not vary much by duration of treatment. Changes in mortality with age were similar to those in the Australian general population.

The Cellular Basis of a Corollary Discharge

Poulet, James F. A.; Hedwig, Berthold

How do animals discriminate self-generated from external stimuli during behavior and prevent desensitization of their sensory pathways? A fundamental concept in neuroscience states that neural signals, termed corollary discharges or efference copies, are forwarded from motor to sensory areas. Neurons mediating these signals have proved difficult to identify. We show that a single, multisegmental interneuron is responsible for the pre- and postsynaptic inhibition of auditory neurons in singing crickets (Gryllus bimaculatus). Therefore, this neuron represents a corollary discharge interneuron that provides a neuronal basis for the central control of sensory responses.

Medical and scientific assessments as the basis for prioritization and resource allocation for new drug treatment - experiences from five years of systematic workIn this study, the process for introduction of new drug treatment in Region Västra Götaland (second largest region in Sweden encompassing 1.6 million inhabitants, 17% of all inhabitants in Sweden) is described. A working group, consisting of persons with relevant expertise and declared conflicts of interest, contributes with medical and scientific assessments as the basis for prioritization and resource allocation. In 2011-2015, 111 new drug treatments were nominated by healthcare representatives, 84 fulfilled the criteria for assessments by the working group, and 57 (68%) were deemed to have high/medium high priority to receive introduction financing according to the severity of disease, the benefit/risk balance, and the level of evidence. When analyzing subsequent costs for new drug treatments for which data could be obtained and specifically evaluated, the results indicate that the process can contribute to rational use of medicines.

Within the scope of the two major international projects of long-term reanalysis for the 20th century coordinated by NOAA (Compo et al. 2011) and ECMWF (Hersbach et al. 2013) the IDL Institute from the University of Lisbon has digitized a large number of long-term stations records from Portugal and former Portuguese Colonies (Stickler et al. 2014). Recently we have finished the digitization of all precipitation values from Ponta Delgada (capital of the Azores archipelago) obtaining an uninterrupted precipitation monthly time series since 1864 and additionally an almost complete corresponding daily precipitation series, with the exception of some years (1864/1872; 1878/1879; 1888/1905; 1931; 1936 and 1938) for which only monthly values are available. Here, we present an annually, seasonally and daily resolution study of the rainfall regime in Ponta Delgada for the last 150 years and the North Atlantic Oscillation (NAO) influence over this precipitation regime. The distribution of precipitation presents an evident seasonal pattern, with a strong difference between the 'rainy season' (November/March) and the 'dry season' (June/August) with very little rainfall. April/May and September/October correspond to the transitional seasons. The mean annual rainfall in Ponta Delgada is approximately 910 mm and is accumulated (on average) in about 120 rainy days. The precipitation regime in Azores archipelago reveals large inter-annual and intra-annual variability and both have increased considerably in the last decades. The entire studied period (1865-2012) shows an increase in the rainfall conditions between a drier earlier period (1865-1938) and a wetter recent period (1939-2012). At daily resolution, we have used an approach based on different characteristics of rain spells (consecutive days with rainfall accumulation) that has been proved to be satisfactory for the analysis of the different parameters related to the rainfall regime (Kutiel and Trigo, 2014).

A receding chin associated with an orthognathic mandible is a common situation and surgical changes in chin position are often required to improve the overall harmony of the face. Genioplasty is one such procedure. Stability of hard and soft tissue changes following genioplasty on a long term basis needs to be assessed. Studies on the stability of hard and soft tissue changes following genioplasty on a short term basis have revealed it as a procedure with good stability. This study is done to assess the stability of hard and soft tissue changes following genioplasty on a long term basis. Pre-surgical, postsurgical and long term post-surgical cephalograms of 15 cases treated by vertical reduction augmentation genioplasty were obtained. Paired t-test was used to compare the changes between pre-surgical, postsurgical and long term postsurgical cephalograms. Findings of this study demonstrated that genioplasty is a stable procedure. After long term follow-up period, there was a relapse of 1.5 mm at the pogonion accounting for 24% of the surgical advancement. This is attributed to the remodeling that occurs at the surgical site, but not the instability due to the surgical procedure. With the present study, it can be concluded that vertical reduction and advancement genioplasty can be considered as an adjunctive procedure that produces predictable results and the bony and soft tissue stability were generally very good.

Chronic anal fissure is a frequent and disabling disease, often affecting young adults. Botulinum toxin and lateral internal sphincterotomy are the main therapeutic options for refractory cases. Botulinum toxin is minimally invasive and safer compared with surgery, which carries a difficult post-operative recovery and fecal incontinence risk. The long-term efficacy of Botulinum toxin is not well known. The aim of this study was to evaluate the long-term efficacy and safety of Botulinum toxin in the treatment of chronic anal fissure. This was a retrospective study at a single center, including patients treated with Botulinum toxin from 2005 to 2010, followed over at least a period of 5 years. All patients were treated with injection of 25U of Botulinum toxin in the intersphincteric groove. The response was registered as complete, partial, refractory and relapse. Botulinum toxin was administered to 126 patients, 69.8% ( n  = 88) were followed over a period of 5 years. After 3 months, 46.6% ( n  = 41) had complete response, 23.9% ( n  = 21) had partial response and 29.5% ( n  = 26) were refractory. Relapse was observed in 1.2% ( n  = 1) at 6 months, 11.4% ( n  = 10) at 1 year, 2.3% ( n  = 2) at 3 years; no relapse at 5 years. The overall success rate was 64.8% at 5 years of follow-up. Botulinum toxin was well tolerated by all patients and there were no complications. The use of Botulinum toxin to treat patients with chronic anal fissure was safe and effective in long-term follow-up.

Studies are needed to evaluate long-term performance of immediately loaded implants with moderately rough surface. This retrospective study evaluated long-term survival and periimplant soft and hard tissue conditions in patients treated with TiUnite implants. Forty-one consecutive patients (mean age, 52.6 years) received 205 Brånemark System Mk III TiUnite implants (145 maxillary, 60 mandibular). The indication was single tooth (n = 7 implants), partial (n = 94), or full arches (n = 104). One hundred thirteen implants were immediately loaded. Cumulative survival rate (CSR) of implants was assessed. Long-term marginal bone remodeling, probing pocket depth (PPD), and periimplant mucosa conditions were assessed. Follow-up averaged 8.8 years (range, 6.6-10.6 years). Eight implants in 5 patients failed. CSR was 96.1% (implant basis) and 87.8% (patient basis) up to 10 years. At the longest follow-up, bone loss averaged 0.43 ± 1.15 mm (n = 173), PPD averaged 3.64 ± 0.74 mm, and periimplant mucosa was healthy in 74.6% of cases. Furthermore, 50.3% and 35.5% of implants scored negative for plaque and bleeding, respectively. No significant difference in CSR and hard and soft tissue conditions was found in the long term between immediately and delayed loaded implants. Implants with TiUnite surface demonstrated excellent long-term survival, marginal bone response, and soft tissue conditions, despite a nonoptimal level of oral hygiene.

Background The short-term quality of life (QoL) in cervical dystonia (CD) after treating with abobotulinum toxin A (Abo-BTX A) and neubotulinum toxin A (Neu-BTX A) have been studied in Thai CD patients. However; the long-term study has not been published. Objective The aim of the present study was to determine long-term improvement of the health-related quality of life (HRQoL) after eight injections of Abo-BTX A over 2 years in CD patients. Patients and methods A 2-year prospective study on the QoL of CD patients, as measured by HRQoL, before and after receiving eight injections of Abo-BTX A at 3-month intervals over a 2-year treatment period was performed. The disease-specific HRQoL was assessed before and after the treatment by using the Cervical Dystonia Impact Profile-58 (CDIP-58) questionnaire. The general HRQoL was assessed by using the Medical Outcomes 36-Item Short Form Health Survey (SF-36), while depressive disorder screening was assessed by using the Center of Epidemiologic Studies-Depression (CES-D) questionnaire. The SF-36 and CES-D questionnaire were administered before treatment and every 3 months before the next injection for a 2-year period. Results A total of 20 CD patients were enrolled from January 2013 to December 2015. CDIP-58 showed a significant improvement after long-term injections of Abo-BTX A in all domains (P < 0.001). However, only vitality domain of SF-36, which assessed general HRQoL, showed a significant improvement after long-term injections (P = 0.037). There was no prevalence of depressive disorder in all patients (CES-D score <20) in this study. Conclusion The Abo-BTX A injections at 3-month intervals over a 2-year period improved the CDIP-58 scores, which assess disease-specific HRQoL, as well as an increased vitality domain of general HRQoL. No patient suffered from depression in this study. PMID:29731634

This study examined whether measures of short-term memory, working memory, and executive functioning in preschool children predict later proficiency in academic achievement at 7 years of age (third year of primary school). Children were tested in preschool (M age = 4 years, 6 months) on a battery of cognitive measures, and mathematics and reading outcomes (from standardized, norm-referenced school-based assessments) were taken on entry to primary school, and at the end of the first and third year of primary school. Growth curve analyses examined predictors of math and reading achievement across the duration of the study and revealed that better digit span and executive function skills provided children with an immediate head start in math and reading that they maintained throughout the first three years of primary school. Visual-spatial short-term memory span was found to be a predictor specifically of math ability. Correlational and regression analyses revealed that visual short-term and working memory were found to specifically predict math achievement at each time point, while executive function skills predicted learning in general rather than learning in one specific domain. The implications of the findings are discussed in relation to further understanding the role of cognitive skills in different mathematical tasks, and in relation to the impact of limited cognitive skills in the classroom environment.

MIS TKA has been shown to offer a reduced in-patient stay, but no clinical difference at two years. Whilst there may be a benefit from earlier discharge, we need to ensure that there are no detrimental effects in the medium and long-term following MIS-TKA. To report the mid-term result from a prospective randomised controlled trial (RCT) comparing MIS-TKA with standard approach for TKA. Using knee score questionnaires, we collected patient reported outcome measures (PROMs) regarding pain and function. Sixty-six patients (from an eligible cohort of 83 patients) completed the mid-term postal follow-up. There was no significant difference between groups for change in score from pre-operative to final follow-up in all three PROMs. Mean MIS and standard group improvement was: AKSS 53 and 51 (p=0.7644), OKS 15 and 16 (p=0.2341) or WOMAC 15 and 15 (p=0.9900) respectively. Both groups showed improvement in pain and function with no significant difference between groups. There was no difference between groups for revision due to malalignment at a mean six year follow-up. In addition to the early benefits regarding hospital stay and complications, we have found that at a mean of six years there was no increase in malalignment, pain or function with MIS techniques.

The demand for accurate and computationally affordable sensitivity and uncertainty techniques is constantly on the rise and has become especially pressing in the nuclear field with the shift to Best Estimate Plus Uncertainty methodologies in the licensing of nuclear installations. Besides traditional, already well developed methods – such as first order perturbation theory or Monte Carlo sampling – Polynomial Chaos Expansion (PCE) has been given a growing emphasis in recent years due to its simple application and good performance. This paper presents new developments of the research done at TU Delft on such Polynomial Chaos (PC) techniques. Our work ismore » focused on the Non-Intrusive Spectral Projection (NISP) approach and adaptive methods for building the PCE of responses of interest. Recent efforts resulted in a new adaptive sparse grid algorithm designed for estimating the PC coefficients. The algorithm is based on Gerstner's procedure for calculating multi-dimensional integrals but proves to be computationally significantly cheaper, while at the same it retains a similar accuracy as the original method. More importantly the issue of basis adaptivity has been investigated and two techniques have been implemented for constructing the sparse PCE of quantities of interest. Not using the traditional full PC basis set leads to further reduction in computational time since the high order grids necessary for accurately estimating the near zero expansion coefficients of polynomial basis vectors not needed in the PCE can be excluded from the calculation. Moreover the sparse PC representation of the response is easier to handle when used for sensitivity analysis or uncertainty propagation due to the smaller number of basis vectors. The developed grid and basis adaptive methods have been implemented in Matlab as the Fully Adaptive Non-Intrusive Spectral Projection (FANISP) algorithm and were tested on four analytical problems. These show consistent good

Infants born prematurely are at risk for neurodevelopmental complications. Early growth is associated with improved later cognition. The relationship of early proportionality and body composition with later cognition is not well established. To assess differences in fat-free mass and adiposity (fat mass, percent body fat) changes in preterm and full-term infants through preschool age and examine associations with early childhood cognition. This is a prospective, observational study in an appropriate for gestational age cohort of 71 patients (20 preterm and 51 full-term) from infancy through preschool age. Anthropometric and body composition measurements via air displacement plethysmography were obtained during infancy at term and 3-4 months (preterm corrected ages), and at 4 years. Cognitive testing occurred at 4 years. Associations of body composition changes between visits with cognitive function were tested using linear regression. In the preterm group, higher term to 4-month corrected age percent body fat gains were associated with lower working memory performance (p = 0.01), and higher 4-month corrected age to 4-year fat-free mass gains were associated with higher full-scale IQ (p = 0.03) and speed of processing performance (p ≤ 0.02). In the full-term group, higher 4-month to 4-year fat mass gains were associated with lower full-scale IQ (p = 0.03). Body composition gains during different time periods are associated with varying areas of cognitive function. These findings may inform interventions aimed at optimal growth. © 2018 S.

Few data are available about obesity surgery in adolescent patients. To assess long-term outcomes after laparoscopic Roux-en-Y gastric bypass (LRYGB) in patients <18 years. University Hospital, Europe. A retrospective study of prospectively collected data of patients <18 years (childhood group; ChG) (n = 28) treated by LRYGB of which 19 were available for follow-up between 2.4 and 10.2 years (mean 7.2 years). This group of patients was matched with an adult control group (AdG) of randomly chosen patients with similar characteristics who underwent LRYGB during the same period. The extensive survey included a telephonic questionnaire. 19 (12 females) of the 28 patients (67.9%) were available for follow-up. Preoperatively, 3 had type 2 diabetes mellitus (T2DM), 1 arterial hypertension, 5 dyslipidemia and 1 sleep apnea. In the ChG, average BMI after 7 years dropped from 38.9 kg/m2 preoperatively to 27.5 kg/m2. In the AdG, average BMI decreased from 39.4 to 27.1 kg/m2 in the same time period (nonsignificant between groups). One patient in the ChG needed a reoperation (internal hernia) versus 3 patients in the AdG (1 leak, 2 obstructions). All patients resolved their initial comorbidities. Two of 12 female patients in the ChG became pregnant 6 and 8 years after surgery, respectively, despite seemingly adequate oral contraception. Compliance with postoperative guidelines was good in 16/19 patients in ChG and in 14/18 patients in the AdG. Overall degree of satisfaction was high: 8.2/10 (SD 1.2, range 6-10) in the ChG and 8.9/10 (SD 1.7, range 5-10) in the AdG. LRYGB seems to be safe, provide good weight loss, and cure comorbidities in an adolescent population. Satisfaction degree is high. Inadvertent pregnancy despite conventional contraception is a possible issue. © 2016 S. Karger GmbH, Freiburg.

In an earlier study, we found that cognitive-behavioral therapy (CBT) delivered by general practitioners (GPs) for fatigue among employees on sick leave was not effective after 12 months. In this study we aim to assess the long-term efficacy of CBT by GPs for fatigue. It was hypothesized that the intervention could prevent deterioration as well as relapse of fatigue complaints and relapse into absenteeism in the long term. Patients who participated in the original randomized controlled trial were followed up 4 years later. Fatigue and absenteeism were the main outcomes. Fatigue and absenteeism were high in the intervention and control groups at the 4-year follow-up. There was no significant difference between the intervention group and the control group on fatigue and absenteeism. The intervention group however tended toward less-favorable outcomes as compared with the control group. Like that of chronic fatigue syndrome, the prognosis of less-advanced fatigue is rather poor. CBT delivered by GPs is not effective in the long term.

Objective We prospectively examine evidence for the sustained effects of early intervention based on a follow-up study of 39 children with ASD who began participation in a randomized clinical trial testing the effectiveness of the Early Start Denver Model (ESDM) at age 18–30 months. The intervention, conducted at a high level of intensity in-home for 2 years, showed evidence of efficacy immediately posttreatment. Method This group of children was assessed at age 6, two years after the intervention ended, across multiple domains of functioning by clinicians naïve to previous intervention group status. Results The ESDM group, on average, maintained gains made in early intervention during the 2-year follow-up period in overall intellectual ability, adaptive behavior, symptom severity, and challenging behavior. No group differences in core autism symptoms were found immediately posttreatment; however, two years later, the ESDM group demonstrated improved core autism symptoms and adaptive behavior as compared with the community-intervention-as-usual (COM) group. The two groups were not significantly different in terms of intellectual functioning at age 6. The two groups received equivalent intervention hours during the original study, but the ESDM group received fewer hours during the follow-up period. Conclusion These results provide evidence that gains from early intensive intervention are maintained 2 years later. Notably, core autism symptoms improved in the ESDM group over the follow-up period relative to the COM group. This improvement occurred at the same time the ESDM group received significantly fewer services. This is the first study to examine the role of early ESDM behavioral intervention initiated below 30 months of age in altering the longer term developmental course of autism. PMID:26088663

We report the variation of the binding energy of the Formic Acid Dimer with the size of the basis set at the Coupled Cluster with iterative Singles, Doubles and perturbatively connected Triple replacements [CCSD(T)] level of theory, estimate the Complete Basis Set (CBS) limit, and examine the validity of the Basis Set Superposition Error (BSSE)-correction for this quantity that was previously challenged by Kalescky, Kraka, and Cremer (KKC) [J. Chem. Phys. 140, 084315 (2014)]. Our results indicate that the BSSE correction, including terms that account for the substantial geometry change of the monomers due to the formation of two strong hydrogen bonds in the dimer, is indeed valid for obtaining accurate estimates for the binding energy of this system as it exhibits the expected decrease with increasing basis set size. We attribute the discrepancy between our current results and those of KKC to their use of a valence basis set in conjunction with the correlation of all electrons (i.e., including the 1s of C and O). We further show that the use of a core-valence set in conjunction with all electron correlation converges faster to the CBS limit as the BSSE correction is less than half than the valence electron/valence basis set case. The uncorrected and BSSE-corrected binding energies were found to produce the same (within 0.1 kcal/mol) CBS limits. We obtain CCSD(T)/CBS best estimates for De = - 16.1 ± 0.1 kcal/mol and for D0 = - 14.3 ± 0.1 kcal/mol, the later in excellent agreement with the experimental value of -14.22 ± 0.12 kcal/mol.

The present commercial market supports many nonsteroidal endocardial pacing leads of differing construction. In order to compare the performance of these configurations, we studied the long-term pacing properties of three representative lead types by randomized clinical trial in 99 patients undergoing a first elective VVI implant. Thirty-one patients received sintered platinum leads, 36 activated pyrolytic carbon leads, and 32 vitreous carbon leads. All received generators capable of noninvasive threshold testing. Acute sensing parameters were R wave amplitude and ST segment elevation measured from the endocardial electrogram. Noninvasive voltage thresholds were measured at implantation, 2 days, 1, 3, and 6 months, and yearly thereafter for 5 years. There were no significant differences between leads in pacing or sensing capabilities at implantation. All three demonstrated similar increases in thresholds, peaking at 1 month, then falling to a plateau by 6 months and did not vary significantly thereafter. There were no significant differences in thresholds between leads during 5 years of follow-up. The lowest mean threshold at 5 years was 0.93 V at 0.5 ms. This study suggests that: (1) although these lead types all perform well, none offers any particular clinical advantage over another; (2) the degree of early threshold peaking precludes immediate postimplant output reduction, but later thresholds are sufficiently low to enable reductions in pacing output; (3) safe low energy pacing requires greater attention to the lead-generator combinations; (4) data obtained at subsequent annual follow-up provided no additional useful clinical information to that obtained at 1 year; and (5) in the absence of other differences, cost can be the deciding factor in lead selection.

Background: A receding chin associated with an orthognathic mandible is a common situation and surgical changes in chin position are often required to improve the overall harmony of the face. Genioplasty is one such procedure. Stability of hard and soft tissue changes following genioplasty on a long term basis needs to be assessed. Studies on the stability of hard and soft tissue changes following genioplasty on a short term basis have revealed it as a procedure with good stability. This study is done to assess the stability of hard and soft tissue changes following genioplasty on a long term basis. Materials and Methods: Pre-surgical, postsurgical and long term post-surgical cephalograms of 15 cases treated by vertical reduction augmentation genioplasty were obtained. Paired t-test was used to compare the changes between pre-surgical, postsurgical and long term postsurgical cephalograms. Results: Findings of this study demonstrated that genioplasty is a stable procedure. After long term follow-up period, there was a relapse of 1.5 mm at the pogonion accounting for 24% of the surgical advancement. This is attributed to the remodeling that occurs at the surgical site, but not the instability due to the surgical procedure. Conclusion: With the present study, it can be concluded that vertical reduction and advancement genioplasty can be considered as an adjunctive procedure that produces predictable results and the bony and soft tissue stability were generally very good.

Studies have shown that moderate alcohol use confers protection against some of the dominant predictors of long-term care placement, including diminished cognitive functioning, physical disability, and injury. But little is known about the association between alcohol use and the likelihood of placement in long-term care facilities. A nationally representative sample of 5,404 community-dwelling Canadians ages 50 years and older at baseline (1994/95) was obtained from the longitudinal National Population Health Survey. Alcohol use categories were developed based on the quantity and frequency of use in the 12 months before the interview. Cox proportional hazards models were used to estimate the association between alcohol use at baseline and subsequent placement in long-term care facilities after adjusting for covariates measured at baseline. During the 14-year follow-up period, 14% of lifetime abstainers, 10% of former drinkers, 7% of infrequent drinkers, 4% of moderate drinkers, and 3% of heavy drinkers were placed in long-term care facilities. Furthermore, the multivariate analysis revealed that abstainers, former drinkers, and infrequent drinkers were more than twice as likely to be placed in long-term care as moderate drinkers. Moderate drinking was protective against placement in long-term care facilities even after adjusting for an array of well-known confounders. The strong protective effect of moderate alcohol use on long-term care entry is likely due to a complex mix of physical, cognitive and psychosocial health factors. PMID:24169370

Auxiliary basis expansions for large-scale electronic structure calculations

2005-01-01

One way to reduce the computational cost of electronic structure calculations is to use auxiliary basis expansions to approximate four-center integrals in terms of two- and three-center integrals, usually by using the variationally optimum Coulomb metric to determine the expansion coefficients. However, the long-range decay behavior of the auxiliary basis expansion coefficients has not been characterized. We find that this decay can be surprisingly slow. Numerical experiments on linear alkanes and a toy model both show that the decay can be as slow as 1/r in the distance between the auxiliary function and the fitted charge distribution. The Coulomb metric fitting equations also involve divergent matrix elements for extended systems treated with periodic boundary conditions. An attenuated Coulomb metric that is short-range can eliminate these oddities without substantially degrading calculated relative energies. The sparsity of the fit coefficients is assessed on simple hydrocarbon molecules and shows quite early onset of linear growth in the number of significant coefficients with system size using the attenuated Coulomb metric. Hence it is possible to design linear scaling auxiliary basis methods without additional approximations to treat large systems. PMID:15845767

On the Usage of Locally Dense Basis Sets in the Calculation of NMR Indirect Nuclear Spin-Spin Coupling Constants

NASA Astrophysics Data System (ADS)

Sanchez, Marina; Provasi, Patricio F.; Aucar, Gustavo A.; Sauer, Stephan P. A.

Locally dense basis sets (basis set for each atom belonging to our studied model compounds depends on its location with respect to the coupled fluorine atoms and on the cis/trans or synperiplanar/antiperiplanar conformation of the molecule. Carbon atoms in the bonding path connecting the coupled fluorine atoms have to be described with better basis sets than the carbon atoms outside this path. For the hydrogen atoms directly connected to the coupling pathway in molecules with trans or antiperiplanar conformations and for all hydrogen atoms not directly connected to the coupling pathway one can employ a minimal basis set with only one s-function. Employing these type of LDBSs we can reduce the number of necessary basis functions by about 30% without losing more than about 1 Hz in accuracy. The analysis of the four contributions to the vicinal fluorine-fluorine coupling constants shows that the non-contact orbital paramagnetic term is the most important contribution followed by the also non-contact spin-dipolar term. The Fermi contact term is the largest contribution only in the synperiplanar conformations of 1,2-difluoroethane and -propane.

Framing effects: behavioral dynamics and neural basis.

PubMed

Zheng, Hongming; Wang, X T; Zhu, Liqi

2010-09-01

This study examined the neural basis of framing effects using life-death decision problems framed either positively in terms of lives saved or negatively in terms of lives lost in large group and small group contexts. Using functional MRI we found differential brain activations to the verbal and social cues embedded in the choice problems. In large group contexts, framing effects were significant where participants were more risk seeking under the negative (loss) framing than under the positive (gain) framing. This behavioral difference in risk preference was mainly regulated by the activation in the right inferior frontal gyrus, including the homologue of the Broca's area. In contrast, framing effects diminished in small group contexts while the insula and parietal lobe in the right hemisphere were distinctively activated, suggesting an important role of emotion in switching choice preference from an indecisive mode to a more consistent risk-taking inclination, governed by a kith-and-kin decision rationality.

Long-term Therapeutic Workplace effects were evaluated in heroin- and cocaine-dependent, unemployed, treatment-resistant young mothers. Participants were paid to work or to train in the Therapeutic Workplace but had to provide drug-free urine samples to gain daily access. Participants (N = 40) were randomly assigned to a Therapeutic Workplace or usual care control group. Therapeutic Workplace participants could work for 3 years. Relative to controls, Therapeutic Workplace participants increased cocaine (28% vs. 54% negative; p = .04) and opiate (37% vs. 60% negative; p = .05) abstinence on the basis of monthly urine samples collected until 3 years after intake. The Therapeutic Workplace can be an effective long-term treatment of cocaine and heroin addiction in poor and chronically unemployed young mothers.

Risks and probabilities of breast cancer: short-term versus lifetime probabilities.

PubMed Central

Bryant, H E; Brasher, P M

1994-01-01

OBJECTIVE: To calculate age-specific short-term and lifetime probabilities of breast cancer among a cohort of Canadian women. DESIGN: Double decrement life table. SETTING: Alberta. SUBJECTS: Women with first invasive breast cancers registered with the Alberta Cancer Registry between 1985 and 1987. MAIN OUTCOME MEASURES: Lifetime probability of breast cancer from birth and for women at various ages; short-term (up to 10 years) probability of breast cancer for women at various ages. RESULTS: The lifetime probability of breast cancer is 10.17% at birth and peaks at 10.34% at age 25 years, after which it decreases owing to a decline in the number of years over which breast cancer risk will be experienced. However, the probability of manifesting breast cancer in the next year increases steadily from the age of 30 onward, reaching 0.36% at 85 years. The probability of manifesting the disease within the next 10 years peaks at 2.97% at age 70 and decreases thereafter, again owing to declining probabilities of surviving the interval. CONCLUSIONS: Given that the incidence of breast cancer among Albertan women during the study period was similar to the national average, we conclude that currently more than 1 in 10 women in Canada can expect to have breast cancer at some point during their life. However, risk varies considerably over a woman's lifetime, with most risk concentrated after age 49. On the basis of the shorter-term age-specific risks that we present, the clinician can put breast cancer risk into perspective for younger women and heighten awareness among women aged 50 years or more.

The potential for tendinous tissues to adapt to functional overload, especially after several years of exposure to heavy-resistance training, is largely unexplored. This study compared the morphological and mechanical characteristics of the patellar tendon and knee extensor tendon-aponeurosis complex between young men exposed to long-term (4 years; n = 16), short-term (12 weeks; n = 15) and no (untrained controls; n = 39) functional overload in the form of heavy-resistance training. Patellar tendon cross-sectional area, vastus lateralis aponeurosis area and quadriceps femoris volume, plus patellar tendon stiffness and Young's modulus, and tendon-aponeurosis complex stiffness, were quantified with MRI, dynamometry and ultrasonography. As expected, long-term trained had greater muscle strength and volume (+58% and +56% vs untrained, both P < .001), as well as a greater aponeurosis area (+17% vs untrained, P < .01), but tendon cross-sectional area (mean and regional) was not different between groups. Only long-term trained had reduced patellar tendon elongation/strain over the whole force/stress range, whilst both short-term and long-term overload groups had similarly greater stiffness/Young's modulus at high force/stress (short-term +25/22%, and long-term +17/23% vs untrained; all P < .05). Tendon-aponeurosis complex stiffness was not different between groups (ANOVA, P = .149). Despite large differences in muscle strength and size, years of resistance training did not induce tendon hypertrophy. Both short-term and long-term overload demonstrated similar increases in high-force mechanical and material stiffness, but reduced elongation/strain over the whole force/stress range occurred only after years of overload, indicating a force/strain specific time-course to these adaptations. © 2017 Scandinavian Physiological Society.

This study aimed to assess the long-term outcomes of radiotherapy in patients with localized gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Twenty-seven patients with Stage I gastric MALT lymphoma were treated with radiotherapy from 1999 to 2010. The median age was 65 years (range: 31-84). Fifteen patients were Helicobacter pylori-negative. Thirteen patients were treated with definitive radiotherapy alone. The other 14 patients who had refractory or residual disease following a prior treatment received salvage radiotherapy. The median dose of the radiotherapy was 30 Gy in 20 fractions (range: 30-39.5 Gy). The median follow-up period was 121 months (range: 8-176 months). The 5- and 10-year overall survival rates for all patients were 92% and 87%, respectively. No patients died from MALT lymphoma. Three patients died of other diseases at 8, 33 and 74 months after radiotherapy (myocardial infarction, pneumonia and hepatocellular carcinoma, respectively). No cases of local recurrence were observed during the follow-up period. There were no serious late gastric, liver or kidney complications during a median follow-up period of over 10 years. Two patients remain alive with distant metastases: a lung metastasis and an abdominal lymph node metastasis at 104 months and 21 months after radiotherapy, respectively. Excellent long-term local control was observed in patients with localized gastric MALT lymphoma after radiotherapy. However, lifelong follow-up should be conducted to detect cases of late recurrence, especially distant metastases. © Oxford University Press 2017.

Physical activity is mandatory if patients are to remain healthy and independent after stroke. Maintenance of motor function, tone, grip strength, balance, mobility, gait, independence in personal and instrumental activities of daily living, health-related quality-of-life and an active lifestyle 4 years post-stroke. A prospective randomized controlled trial. Four years post-stroke, 37 of the 75 participating persons were eligible for follow-up; 19 (54.3%) from the intensive exercise group and 18 (45%) from the regular exercise group. Both groups were performing equally well with no significant differences in total scores on the BI (p = 0.3), MAS (p = 0.4), BBS (p = 0.1), TUG (p = 0.08), 6MWT (p = 0.1), bilateral grip strength (affected hand, p = 0.8; non-affected hand, p = 0.9) nor in the items of NHP (p > 0.005). Independence in performing the IADL was 40%, while 60% had help from relatives or community-based services. This longitudinal study shows that persons with stroke in two groups with different exercise regimes during the first year after stroke did not differ in long-term outcomes. Both groups maintained function and had a relatively active life style 4 years after the acute incident. The results underline the importance of follow-up testing and encouragement to exercise, to motivate and sustain physical activity patterns, to maintain physical function, not only in the acute but also in the chronic phase of stroke.

Short and long-term career plans of final year dental students in the United Arab Emirates

Background New dental schools have been established to train dentists in many parts of the world. This study examines the future dental workforce from the first dental school in the United Arab Emirates [UAE]; the aim of this study was to explore the short and long-term career aspirations of the final year dental students in the UAE in relation to their demography. Method Final year dental students of the Ajman University’s College of Dentistry (n=87) were invited to participate in a self-completion questionnaire survey. Descriptive analysis, chi-square tests, and binary logistic regression analysis were carried out on career aspirations using SPSS v20. Results Eighty-two percent of students (n=71) responded, the majority of whom were female (65%; n=46). Ethnicity was reported as: ‘other Arab’ (61%; n=43), ‘Emirati’ (17%, n=12), and ‘Other’ (21%, n=15). In the short-term, 41% (n=29) expressed a desire to work in government training centres, with Emirati students significantly more likely to do so (p=0.002). ‘Financial stability’ (80%; n=57) and ‘gaining professional experience’ (76%; n=54) emerged as the most important influences on their short-term career plans. The vast majority of students wished to specialise in dentistry (92%; n=65) in the longer term; logistic regression analysis revealed that the odds of specialising in the most popular specialties of Orthodontics and Oral and Maxillofacial Surgery were less for the ‘Other’ ethnic group when compared with ‘Emirati’ students (0.26; 95% CI 0.068-0.989; p=0.04). Almost three-quarters of the students overall (72%; n=51) intended to work full-time. ‘High income/financial security’ (97%; n=69), ‘standard of living’ (97%; n=69), ‘work/life balance’ (94%; n=67), and ‘professional fulfilment’ (87%; n=62) were reported by the students as the most influential items affecting their long-term professional career choices.

Research into the motivation and expectations of the emerging workforce and their short-term expectations has already been reported with a view to informing professional and policy decisions. The objective of this component of the research programme was to examine the long-term goals and perceived influences on final year dental students' professional careers. Univariate analysis of a self completed questionnaire survey of all final year dental students from King's College London, comprising questions on demography, long-term career goals and influences, proposed commitment to dentistry, commitment to healthcare systems and the influences thereon. Statistical analysis included Chi Squared tests for linear association. Ninety per cent of students responded to this survey (n = 126), the majority of whom were aged 23 years (59%), female (58%) and Asian (70%). Long-term career goals were fairly evenly split between 'dentist with a special interest' (27%), 'primary dental care practitioner' (26%) and 'specialist' (25%), with 19% not certain. Only 60% of total respondents anticipated working full-time in the long-term (79% males cf 52% females; p = 0.00). The vast majority of respondents (> or =80%) identified 'work-life balance', 'financial stability' and 'professional development' as 'important' or 'very important' influences on the number of future sessions. Females were significantly more likely to rate childcare commitments as an important influence on their future working capacity compared with males (p = 0.00). A wide range of factors were considered important or very important in making the NHS attractive, led by support for professional development (88%) and feeling valued by patients (88%), as well as funding, time with patients, rewards for prevention and practical issues such as dental materials and premises. Females were significantly more likely than males to be attracted to work within the NHS by 'childcare support' (p = 0.02), 'retraining facilities after

Ulnar collateral ligament reconstruction (UCLR) has afforded baseball players with excellent results; however, previous studies have described only short-term outcomes. To evaluate long-term outcomes after UCLR in baseball players. Case series; Level of evidence, 4. All UCLRs performed on competitive baseball players with a minimum 10-year follow-up were identified. Surgical data were collected prospectively and patients were surveyed by telephone follow-up, during which scoring systems were used to assess baseball career and post-baseball career outcomes. Of 313 patients, 256 (82%) were contacted at an average of 12.6 years; 83% of these baseball players (90% pitchers) were able to return to the same or higher level of competition in less than 1 year, but results varied according to preoperative level of play. Baseball career longevity was 3.6 years in general and 2.9 years at the same or higher level of play, but major and minor league players returned for longer than did collegiate and high school players after surgery (P < .001). Baseball retirement typically occurred for reasons other than elbow problems (86%). Many players had shoulder problems (34%) or surgery (25%) during their baseball career, and these occurrences most often resulted in retirement attributable to shoulder problems (P < .001). For post-baseball career outcomes, 92% of patients were able to throw without pain, and 98% were still able to participate in throwing at least on a recreational level. The 10-year minimum follow-up scores (mean ± standard deviation) for the Disabilities of the Arm, Shoulder and Hand (DASH), DASH work module, and DASH sports module were 0.80 ± 4.43, 1.10 ± 6.90, and 2.88 ± 11.91, respectively. Overall, 93% of patients were satisfied, with few reports of persistent elbow pain (3%) or limitation of function (5%). Long-term follow-up of UCLRs in baseball players indicates that most patients were satisfied, with few reports of persistent elbow pain or limitation of

Transcatheter aortic valve implantation/replacement (TAVI/TAVR) is becoming more frequently used to treat aortic stenosis (AS), with increasing push for the procedure in lower risk patients. Numerous randomized controlled trials have demonstrated that TAVI offers a suitable alternative to the current gold standard of surgical aortic valve replacement (SAVR) in terms of short-term outcomes. The present review evaluates long-term outcomes following TAVI procedures. Literature search using three electronic databases was performed up to June 2017. Studies which included 20 or more patients undergoing TAVI procedures, either as a stand-alone or concomitant procedure and with a follow-up of at least 5 years, were included in the present review. Literature search and data extraction were performed by two independent researchers. Digitized survival data were extracted from Kaplan-Meier curves in order to re-create the original patient data using an iterative algorithm and subsequently aggregated for analysis. Thirty-one studies were included in the present analysis, with a total of 13,857 patients. Two studies were national registries, eight were multi-institutional collaborations and the remainder were institutional series. Overall, 45.7% of patients were male, with mean age of 81.5±7.0 years. Where reported, the mean Logistic EuroSCORE (LES) was 22.1±13.7 and the mean Society of Thoracic Surgeons (STS) score was 9.2±6.6. The pooled analysis found 30-day mortality, cerebrovascular accidents, acute kidney injury (AKI) and requirement for permanent pacemaker (PPM) implantation to be 8.4%, 2.8%, 14.4%, and 13.4%, respectively. Aggregated survival at 1-, 2-, 3-, 5- and 7-year were 83%, 75%, 65%, 48% and 28%, respectively. The present systematic review identified acceptable long-term survival results for TAVI procedures in an elderly population. Extended follow-up is required to assess long-term outcomes following TAVI, particularly before its application is extended into

The TRMM rainfall products are inter-compared among themselves and to the 23 year, monthly, globally complete precipitation analysis of the World Climate Research Program's (WCRP/ GEWEX) Global Precipitation Climatology Project (GPCP). Ways in which the TRMM-based estimates can be used to improve the long-term data set are described. These include improvement of the passive microwave algorithm that is applied to the 15 year SSM/I record and calibration or adjustment of the current GPCP fields utilizing the 4-5 year overlap of TRMM and GPCP. A comparison of the GPCP monthly surface precipitation fields and the TRMM-based multi-satellite analyses indicates that the two are similar, but have significant differences that relate to the different input data sets. Although on a zonal average basis over the ocean the two analyses are similar in the deep Tropics, there are subtle differences between the eastern and western Pacific Ocean in the relative magnitudes. In mid-latitudes the GPCP has somewhat larger mean precipitation than TRMM. Statistical comparisons of TRMM and GPCP monthly fields are carried out in terms of histogram matching for both ocean and land regions and for small areas to diagnose differences. These comparisons form the basis for a TRMM calibration of the GPCP fields using matched histograms over regional areas as a function of season. Although final application of this procedure will likely await the Version 6 of the TRMM products, tests using Version 5 are shown that provide a TRMM-calibrated GPCP version that will produce an improved climatology and a more accurate month-to-month precipitation analysis for the last 20 years.

Long-term effects of a factory closure: unemployment and disability during ten years' follow-up.

Westin, S; Schlesselman, J J; Korper, M

1989-01-01

The consequences of a factory closure on future employment, disability and death were investigated in a 10-year prospective follow-up study in a general practice setting. The study population consisted of 85 persons who lost their jobs when a brisling sardine factory close to Bergen in Norway was shut down in 1975. The employees of a nearby "sister factory" within the same company were chosen as a control population, consisting of 87 persons. After the factory closure, the annual employment rate of the study group showed a steady rise to a maximum level of 44% within 6 years, but even after 10 years never matched the employment rate of the controls. The cumulative rates of disability pension, granted for medical conditions only, was more than three times higher in the study group than among controls from the second through the fourth year of follow-up. This excess of disabilities then stayed relatively constant at approximately 17 per 100 persons from 5 to 10 years after the shut-down. Given present days' unemployment, the results of this investigation point to the importance of acknowledging a long-term effect of job-loss on health and social readjustment.

The objective of this study was to investigate predictors of long-term recovery from eating disorders 22 years after entry into a longitudinal study. One hundred and seventy-six of the 228 surviving participants (77.2%) were re-interviewed 20-25 years after study entry using the Longitudinal Interval Follow-up Evaluation to assess ED recovery. The sample consisted of 100 women diagnosed with anorexia nervosa (AN) and 76 with bulimia nervosa (BN) at study entry. A comorbid diagnosis of major depression at the start of the study strongly predicted having a diagnosis of AN-Restricting type at the 22-year assessment. A higher body mass index (BMI) at study intake decreased the odds of being diagnosed with AN-Binge Purge type, relative to being recovered, 22 years later. The only predictor that increased the likelihood of having a diagnosis of BN at the 22-year assessment was the length of time during the study when the diagnostic criteria for BN were met. Together, these results indicate that the presence and persistence of binge eating and purging behaviors were poor prognostic indicators and that comorbidity with depression is particularly pernicious in AN. Treatment providers might pay particular attention to these issues in an effort to positively influence recovery over the long-term. Copyright © 2017 Elsevier Ltd. All rights reserved.

The Edwards Lifesciences Prima Plus stentless valve (ELSV) is a bioprosthesis manufactured from a porcine aortic root. The study aim was to evaluate late clinical outcomes after aortic valve replacement (AVR) with ELSV implanted as a miniroot in patients with aortic valve disease. Between 1993 and 2004, 318 patients (232 males, 86 females; mean age 69 +/- 9 years; range: 37-83 years) underwent AVR with the ELSV. Preoperatively, 102 patients (32%), 162 (51%) and 54 (17%) were in NYHA classes I/II, III and IV, respectively. Aortic stenosis, aortic regurgitation and combined lesions were present in 124 patients (39%), 114 (36%) and 41 (13%), respectively. Twenty patients (6%) were referred for an acute aortic dissection, 20 (6%) for an aortic root aneurysm, and 139 (44%) had an associated aneurysmal dilatation of the ascending aorta. The ascending aorta was replaced in 159 patients (50%); aortic arch replacement was required in 10 (3%). Coronary artery bypass graft was performed in 86 patients (27%). The follow up was based on clinical data. Operative mortality was 5% (n = 17). There were 49 late deaths (5.2%/pt-yr). Valve-related mortality occurred in 10 patients (1%/pt-yr). Actuarial survival at five and 10 years was 78% and 33%, respectively. Actuarial freedom from valve reoperation and structural valve deterioration at 10 years were 100% and 64%. Actuarial freedom from embolic events and endocarditis at 10 years were 84% and 81%, respectively. The ELSV, when implanted as a miniroot, provided good early and long-term results in terms of survival and freedom from major complications.

Jones MP, Bartrop RW, Forcier L, Penny R. The long-term impact of bereavement upon spouse health: a 10-year follow-up. This study is the first to examine the effect of bereavement of a first-degree family member on subsequent morbidity over a 10-year follow-up period. A sample of bereaved subjects (n = 72) were compared with a control group (n = 80) recruited in the same period with respect to morbidity experience during follow-up. Morbidity events were ascertained from the subject themselves, their health care providers and these sources were also compared. Bereavement was associated with an elevated total burden of illness as well as with mental health and circulatory system categories diagnosed according to the International Classification of Diseases - Clinically Modified (ICD-9) classification system. The elevation ranged from approximately 20% for any illness to 60-100% among circulatory system disorders. Although in an earlier study there was a downregulation of T-cell function in the bereaved during the first 8 weeks, there was no evidence that the bereavement was associated with increased morbidity in the respiratory or immune system ICD-9 categories long-term. Past epidemiological research has indicated that bereavement of a close family member is associated with adverse health consequences of a generalised morbidity. Our study suggests an increase in mental health and circulatory system effects in particular. Further research is required to determine whether other systems are also affected by bereavement.

An implementation of the QMR method based on coupled two-term recurrences

NASA Technical Reports Server (NTRS)

Freund, Roland W.; Nachtigal, Noeel M.

1992-01-01

The authors have proposed a new Krylov subspace iteration, the quasi-minimal residual algorithm (QMR), for solving non-Hermitian linear systems. In the original implementation of the QMR method, the Lanczos process with look-ahead is used to generate basis vectors for the underlying Krylov subspaces. In the Lanczos algorithm, these basis vectors are computed by means of three-term recurrences. It has been observed that, in finite precision arithmetic, vector iterations based on three-term recursions are usually less robust than mathematically equivalent coupled two-term vector recurrences. This paper presents a look-ahead algorithm that constructs the Lanczos basis vectors by means of coupled two-term recursions. Implementation details are given, and the look-ahead strategy is described. A new implementation of the QMR method, based on this coupled two-term algorithm, is described. A simplified version of the QMR algorithm without look-ahead is also presented, and the special case of QMR for complex symmetric linear systems is considered. Results of numerical experiments comparing the original and the new implementations of the QMR method are reported.

A wavelet basis selection procedure is presented for wavelet regression. Both the basis and the threshold are selected using cross-validation. The method includes the capability of incorporating prior knowledge on the smoothness (or shape of the basis functions) into the basis selection procedure. The results of the method are demonstrated on sampled functions widely used in the wavelet regression literature. The results of the method are contrasted with other published methods.

In neuroscience, population coding theory demonstrates that neural assemblies can achieve fault-tolerant information processing. Mapped to nanoelectronics, this strategy could allow for reliable computing with scaled-down, noisy, imperfect devices. Doing so requires that the population components form a set of basis functions in terms of their response functions to inputs, offering a physical substrate for computing. Such a population can be implemented with CMOS technology, but the corresponding circuits have high area or energy requirements. Here, we show that nanoscale magnetic tunnel junctions can instead be assembled to meet these requirements. We demonstrate experimentally that a population of nine junctions can implement a basis set of functions, providing the data to achieve, for example, the generation of cursive letters. We design hybrid magnetic-CMOS systems based on interlinked populations of junctions and show that they can learn to realize non-linear variability-resilient transformations with a low imprint area and low power.

We report on the long-term outcomes of the distal urethral polypropylene sling for stress urinary incontinence in a patient cohort that was closely followed and whose outcomes were reported at 1 and 5 years after surgery. We performed a prospective study of all consecutive patients who underwent a distal urethral polypropylene sling procedure between November 1999 and April 2000. The 1 and 5-year outcomes for this particular patient cohort were previously reported. At the minimum 11-year followup, outcome was determined by patient self-assessment including validated questionnaires. A total of 69 patients were followed prospectively and followup was obtained for 30. Of those lost to followup 10 were deceased and 5 were cognitively impaired. Mean patient age at followup was 73 years (range 40 to 97). More than 11 years after surgery 48% of patients reported no stress urinary incontinence symptoms and 63% were never bothered by stress urinary incontinence. Patients reported a mean overall symptom improvement of 64% compared to 81% at 5 years. Overall 82% of patients met the criteria for treatment success by symptom scores and 80% met the criteria by bother scores. The distal urethral polypropylene sling procedure has excellent long-term durability in the treatment of stress urinary incontinence, in addition to low morbidity and low cost as previously described. Eleven years after the procedure the majority of patients report symptom improvement. Nevertheless, many older patients are unable to participate in followup. When choosing an anti-incontinence procedure, durability should be considered in light of patient age given that the theoretical advantages of long-term durability are limited by cognitive decline and mortality.

2013-09-01

Blonanserin is a relatively new atypical antipsychotic drug, and has been used in Korea and Japan for 1 and 3 years, respectively. Therefore, the clinical characteristics of blonanserin remain unclear. In this study, to clarify the features of blonanserin, we performed prospective and long-term comparative investigations of patients treated with blonanserin. We followed 10 psychiatric patients who were switched to blonanserin from other antipsychotics for 1 year (schizophrenia: 8; mental retardation: 2). In the light of quality of life, we focused on adverse effects of patients during the follow-up. In the long-term follow-up, (i) hyperprolactinemia is more frequently in risperidone than in blonanserin; however, it is more often in blonanserin than in olanzapine; and (ii) weight gain is more common in olanzapine than in blonanserin. We switched to blonanserin from other antipsychotic drugs within the same case, and then followed the case for 1 year. We consider that long-term observations within the same case lead to obvious comparisons among drugs. On the basis of our findings, we conclude that blonanserin may be useful for the maintenance treatment of schizophrenia without inducing hyperprolactinemia and weight gain.

Methods Univariate analysis of a self completed questionnaire survey of all final year dental students from King's College London, comprising questions on demography, long-term career goals and influences, proposed commitment to dentistry, commitment to healthcare systems and the influences thereon. Statistical analysis included Chi Squared tests for linear association. Results Ninety per cent of students responded to this survey (n = 126), the majority of whom were aged 23 years (59%), female (58%) and Asian (70%). Long-term career goals were fairly evenly split between 'dentist with a special interest' (27%), 'primary dental care practitioner' (26%) and 'specialist' (25%), with 19% not certain. Only 60% of total respondents anticipated working full-time in the long-term (79% males cf 52% females; p = 0.00). The vast majority of respondents (≥80%) identified 'work-life balance', 'financial stability' and 'professional development' as 'important' or 'very important' influences on the number of future sessions. Females were significantly more likely to rate childcare commitments as an important influence on their future working capacity compared with males (p = 0.00). A wide range of factors were considered important or very important in making the NHS attractive, led by support for professional development (88%) and feeling valued by patients (88%), as well as funding, time with patients, rewards for prevention and practical issues such as dental materials and premises. Females were significantly more likely than males to be attracted to work within the NHS by 'childcare support' (p = 0

Philosophers of science have emphasized the need for primitive terms, or "givens," in the construction of theory for any discipline. While there are inherent dangers regarding the use of primitive terms, they can have great value in serving as the basis for minimum terms, which are primitive terms unique to a discipline.

This report provides a further analysis of the year 4 weight losses in the Look AHEAD (Action for Health in Diabetes) study and identifies factors associated with long-term success. A total of 5,145 overweight/obese men and women with type 2 diabetes were randomly assigned to an intensive lifestyle intervention (ILI) or a usual care group, referred to as Diabetes Support and Education (DSE). ILI participants were provided approximately weekly group or individual treatment in year 1; continued but less frequent contact was provided in years 2-4. DSE participants received three group educational sessions in all years. As reported previously, at year 4, ILI participants lost an average of 4.7% of initial weight, compared with 1.1% for DSE (P < 0.0001). More ILI than DSE participants lost ≥ 5% (46% vs. 25%, P < 0.0001) and ≥ 10% (23% vs. 10%, P < 0.0001) of initial weight. Within the ILI, achievement of both the 5% and 10% categorical weight losses at year 4 was strongly related to meeting these goals at year 1. A total of 887 participants in ILI lost ≥ 10% at year 1, of whom 374 (42.2%) achieved this loss at year 4. Participants who maintained the loss, compared with those who did not, attended more treatment sessions and reported more favorable physical activity and food intake at year 4. These results provide critical evidence that a comprehensive lifestyle intervention can induce clinically significant weight loss (i.e., ≥ 5%) in overweight/obese participants with type 2 diabetes and maintain this loss in more than 45% of patients at 4 years.

Tobiska, Sandra; Krastl, Gabriel

2018-05-17

This case report presents long-term results following horizontal root fracture of both maxillary central incisors in a 19-year-old woman with aggressive periodontitis. Due to extensive marginal bone loss and the close proximity of the fracture lines to the bottoms of the periodontal pockets, the prognosis of both teeth was uncertain at the time of the accident. Nevertheless, a conservative treatment strategy consisting of splinting and nonsurgical periodontal therapy was initiated. Follow-up at 12 years after the start of treatment revealed a stable situation from clinical and radiologic perspectives. Permanent fixation to the adjacent teeth and regular supportive periodontal care were the basis for a favorable long-term prognosis.

Abstract Transthyretin hereditary amyloid polyneuropathy, also traditionally known as transthyretin familial amyloid polyneuropathy (ATTR-FAP), is a rare, relentless, fatal hereditary disorder. Tafamidis, an oral, non-NSAID, highly specific transthyretin stabilizer, demonstrated safety and efficacy in slowing neuropathy progression in early-stage ATTRV30M-FAP in a 1.5-year, randomized, double-blind, placebo-controlled trial, and 1-year open-label extension study, with a second long-term open-label extension study ongoing. Subgroup analysis of the effectiveness of tafamidis in the pivotal study and its open-label extensions revealed a relatively cohesive cohort of patients with mild neuropathy (i.e. Neuropathy Impairment Score for Lower Limbs [NIS-LL] ≤ 10) at the start of active treatment. Early treatment with tafamidis for up to 5.5 years (≥1 dose of tafamidis meglumine 20 mg once daily during the original trial or after switching from placebo in its extension) resulted in sustained delay in neurologic progression and long-term preservation of nutritional status in this cohort. Mean (95% CI) changes from baseline in NIS-LL and mBMI were 5.3 (1.6, 9.1) points and −7.8 (−44.3, 28.8) kg/m2 × g/L at 5.5 years, respectively. No new safety issues or side effects were identified. These data represent the longest prospective evaluation of tafamidis to date, confirm a favorable safety profile, and underscore the long-term benefits of early intervention with tafamidis. Trial Registration: ClincalTrials.gov Identifier: NCT00409175, NCT00791492, and NCT00925002. PMID:27494299

Intravenous thrombolysis with alteplase is one of the few approved treatments for acute ischemic stroke; nevertheless, little is known about its long-term effects on survival and recovery because clinical trials follow-up times are limited. Patients registered between January 2005 and December 2015, to the population-based South London Stroke Register of first-ever strokes. Propensity score was used to match thrombolyzed and control cases to a 1:2 ratio by demographical and clinical covariates. The primary outcome was survival up to 10 years using Kaplan-Meier estimates, Cox proportional hazards, and restricted mean survival time. Secondary outcomes included stroke recurrence and functional status (Barthel Index and Frenchay Activities Index scores) at 5 years. From 2052 ischemic strokes, 246 treated patients were matched to 492 controls. Median follow-up time 5.45 years (interquartile range, 4.56). Survival was higher in the treatment group (median, 5.72 years) compared with control group (4.98 years, stratified log-rank test <0.001). The number needed to treat to prevent 1 death at 5 years was 12 and 20 at 10 years. After Cox regression analysis, thrombolysis reduced risk of mortality by 37% (hazard ratio, 0.63; 95% confidence interval [CI], 0.48-0.82) at 10 years; however, after introducing a multiplicative interaction term into the model, mortality risk reduction was 42% (hazard ratio, 0.58; 95% CI, 0.40-0.82) at 10 years for those arriving within 3 hours to the hospital. On average, in a 10-year period, treated patients lived 1 year longer than controls. At 5 years, thrombolysis was associated with independence (Barthel Index≥90; odds ratio, 3.76; 95% CI, 1.22-13.34) and increased odds of a higher Frenchay Activities Index (proportional odds ratio, 2.37; 95% CI, 1.16-4.91). There was no difference in stroke recurrence. Thrombolysis with intravenous alteplase is associated with improved long-term survival and functional status after ischemic stroke. © 2018

The neutrino–neutrino interaction effects in supernovae: The point of view from the ‘matter’ basis

Galais, Sebastien; Kneller, James; Volpe, Cristina

2012-01-19

We consider the Hamiltonian for neutrino oscillations in matter in the case of arbitrary potentials including off-diagonal complex terms. We derive the expressions for the corresponding Hamiltonian in the basis of the instantaneous eigenstates in matter, in terms of quantities one can derive from the flavor-basis Hamiltonian and its derivative, for an arbitrary number of neutrino flavors. We make our expressions explicit for the two-neutrino flavor case and apply our results to the neutrino propagation in core-collapse supernovae where the Hamiltonian includes both coupling to matter and to neutrinos. We show that the neutrino flavor evolution depends on the mixingmore » matrix derivatives involving not only the derivative of the matter mixing angles but also of the phases. In particular, we point out the important role of the phase derivatives, that appear due to the neutrino-neutrino interaction, and show how it can cause an oscillating degeneracy between the diagonal elements of the Hamiltonian in the basis of the eigenstates in matter. Lastly, our results also reveal that the end of the synchronization regime is due to a rapid increase of the phase derivative and identify the condition to be fulfilled for the onset of bipolar oscillations involving both the off-diagonal neutrino-neutrino interaction contributions and the vacuum terms.« less

Background: Plantar fasciitis (PF) affects 7% to 10% of the population. The long-term prognosis is unknown. Purpose: Our study had 4 aims: (1) to assess the long-term prognosis of PF, (2) to evaluate whether baseline characteristics (sex, body mass index, age, smoking status, physical work, exercise-induced symptoms, bilateral heel pain, fascia thickness, and presence of a heel spur) could predict long-term outcomes, (3) to assess the long-term ultrasound (US) development in the fascia, and (4) to assess whether US-guided corticosteroid injections induce atrophy of the heel fat pad. Study Design: Cohort study; Level of evidence, 3. Methods: From 2001 to 2011 (baseline), 269 patients were diagnosed with PF based on symptoms and US. At follow-up (2016), all patients were invited to an interview regarding their medical history and for clinical and US re-examinations. Kaplan-Meier survival estimates were used to estimate the long-term prognosis, and a multiple Cox regression analysis was used for the prediction model. Results: In all, 174 patients (91 women, 83 men) participated in the study. All were interviewed, and 137 underwent a US examination. The mean follow-up was 9.7 years from the onset of symptoms and 8.9 years from baseline. At follow-up, 54% of patients were asymptomatic (mean duration of symptoms, 725 days), and 46% still had symptoms. The risk of having PF was 80.5% after 1 year, 50.0% after 5 years, 45.6% after 10 years, and 44.0% after 15 years from the onset of symptoms. The risk was significantly greater for women (P < .01) and patients with bilateral pain (P < .01). Fascia thickness decreased significantly in both the asymptomatic and symptomatic groups (P < .01) from 6.9 mm and 6.7 mm, respectively, to 4.3 mm in both groups. Fascia thickness (P = .49) and presence of a heel spur (P = .88) at baseline had no impact on prognosis. At follow-up, fascia thickness and echogenicity had normalized in only 24% of the asymptomatic group. The mean fat pad

Our aim was to assess the long-term outcome for minor forefoot amputations. A retrospective study of 126 patients who had such amputations between 1999 and 2004 was performed. Patients were divided into 2 groups, diabetic (group A: 79 patients) and nondiabetic (group B: 47 patients). Angiograms were requested in 45 patients in group A compared with 31 patients in group B (P = ·77). In group A, 11 patients underwent further ipsilateral amputations compared with 30 patients in group B (P = ·02.). The 2 groups were equally likely to have vascular reconstruction (35% vs 37%). The overall 5-year mortality was 27%, with 58% of deaths occurring within the first year. This study shows that foot amputees have high mortality and reintervention rates. Adequate utilization of vascular services, extra vigilance in the prevention of complications, and risk factor modifications are required to improve postoperative outcomes.

Long-term (5 years), high daily dosage of dietary agmatine--evidence of safety: a case report.

PubMed

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

Towards an epistemological basis for andragogy in midwifery education.

Ho, E

In designing the curriculum for pre and post registration midwifery courses, the author has utilised an andragogical model. This term refers to the art and science of teaching adults (Knowles 1978). The ideas that Knowles (1978) put forward about andragogy while not new, have been implemented in adult education and are certainly relevant to the modern practice of midwifery education. The aim of this paper is to examine the two extreme philosophical views about the nature of man and to provide an epistemological basis for andragogy in midwifery education.

The purpose of this study was to investigate the long-term effectiveness of a spine care education programme conducted in 9- to 11-year-old schoolchildren. The study sample included 96 intervention subjects and 98 controls (9- to 11-year-olds at baseline). Intervention consisted of a 6-week school-based back education programme (predominantly biomechanically oriented) and was implemented by a physical therapist. Self-reported outcomes on back care knowledge, spinal care behaviour, self-efficacy towards favourable back care behaviour, prevalence of back and neck pain during the week and fear-avoidance beliefs were evaluated by the use of questionnaires. Post-tests were performed within 1 week after programme completion, after 1 year and after 8 years. Whereas the educational back care programme resulted in increased back care knowledge up to adulthood (P < 0.001), intervention did not change spinal care behaviour or self-efficacy. Pain prevalence figures increased less in the experimental group compared to the controls over the 8-year time span, yet statistical significance was not reached. Dropout analysis revealed spinal pain prevalence rates to be different in both groups throughout the study, including at baseline. Back education at young age did not reinforce fear-avoidance beliefs up to adulthood. Predominantly biomechanical oriented back education in elementary schoolchildren is effective in improving the cognitive aspect of back care up to adulthood, yet not in changing actual behaviour or self-efficacy. The current study does not provide evidence that educational back care programmes have any impact on spinal pain in adulthood. The true long-term impact of school-based spinal health interventions on clinically relevant outcome measures merits further attention.

Background. Neonatal hyperbilirubinemia (HB) may cause severe neurological damage, but serious consequences are effectively controlled by phototherapy and blood exchange transfusion. HB is still a serious health problem in economically compromised parts of the world. The long term outcome has been regarded favorable based on epidemiological data, but has not been confirmed in prospective follow-up studies extending to adulthood. Methods. We studied the long term consequences of HB in a prospective birth cohort of 128 HB cases and 82 controls. The cases are part of a neonatal at-risk cohort (n = 1196) that has been followed up to 30 years of age. HB cases were newborns ≥ 2500 g birth weight and ≥ 37 weeks of gestation who had bilirubin concentrations > 340 µmol/l or required blood exchange transfusion. Subjects with HB were divided into subgroups based on the presence (affected HB) or absence (unaffected HB) of diagnosed neurobehavioral disorders in childhood, and compared with healthy controls. Subjects were seen at discharge, 5, 9 and 16 years of life and parent's and teacher's assessments were recorded. At 30 years they filled a questionnaire about academic and occupational achievement, life satisfaction, somatic and psychiatric symptoms including a ADHD self-rating score. Cognitive functioning was tested using ITPA, WISC, and reading and writing tests at 9 years of life. Results. Compared to controls, the odds for a child with HB having neurobehavioral symptoms at 9 years was elevated (OR = 4.68). Forty-five per cent of the HB group were affected by cognitive abnormalities in childhood and continued to experience problems in adulthood. This was apparent in academic achievement (p < 0.0001) and the ability to complete secondary (p < 0.0001) and tertiary (p < 0.004) education. Also, the subgroup of affected HB reported persisting cognitive complaints e.g., problems with reading, writing and mathematics. Childhood symptoms of hyperactivity/impulsivity (p < 0

Single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) is a modification of Roux-en-Y duodenal switch (RYDS). Long-term data on this operation is lacking in the literature. We reviewed our mid-term data of this RYDS modification. To analyze the outcomes with SADI-S at 4 years. Data from patients who underwent a primary SADI-S procedure performed by three surgeons at a single institution from June 2013 through February 2018 were retrospectively reviewed. All revision bariatric surgeries were excluded. Regression analyses were performed for all follow-up weight loss data. There were 437 patients in our database. The pre-operative mean body mass index (BMI) was 49.8 ± 8.8 kg/m 2 . The 30-day complication rate was 7.7%. The 30-day readmission, reoperation, and mortality rates were 1.8, 1.3, and 0.2%, respectively. The long-term complication rate was 10.9%. Seventy-nine patients were 4 years post SADI-S surgery and follow-up was possible for 44 patients (55.7%). At 4 years, patients had an average change in BMI of 18.1 ± 6 units with an excess weight loss (EWL) of 85.7 ± 27.3%. At 4 years, 97.6% patients were able to maintain HbA1c < 6% with or without the use of diabetic medication. There was a statistically significant difference between most of the pre-operative and post-operative nutritional data. SADI-S is a safe and effective procedure in both short- and mid-term data points. Diabetes resolution and weight loss appear similar to traditional RYDS and better than RYGB.

The limiting factor in organ transplantation is the availability of organs. Ongoing work to improve donation rates both at the public and the organizational level in donating hospitals is essential. We also think that encouragement of live donation is important, and the possibility of ABO incompatible transplantation has increased the number of LD transplantations. The one-year graft survival rate is excellent and focus has shifted towards achieving long-term results to reduce the attrition rate. There is also an increasing interest in studying and working to reduce comorbidities on a long-term basis and thus, improve survival rates and recipient quality of life.

In 2005, the Long-Term Career Outcome Study (LTCOS) was established by the Dean, F. Edward Hébert School of Medicine, Uniformed Services University of the Health Sciences (USU). The original charge to the LTCOS team was to establish an electronic database of current and past students at USU. Since its inception, however, the LTCOS team has broadened its mission and started collecting and analyzing data on a continuous basis for the purposes of program evaluation and, in some cases, research. The purpose of this commentary is to review the history of the LTCOS, including details about USU, a brief review of prior LTCOS work, and progress made since our last essay on LTCOS efforts. This commentary also provides an introduction to the special issue, which is arranged as a series of articles that span the medical education continuum (i.e., before, during, and after medical school). The relative balance of articles in each phase of training represents the LTCOS team's efforts to address the entire continuum of medical education.

Alcohol disorders and re-employment in a 5-year follow-up of long-term unemployed.

Claussen, B

1999-01-01

To establish whether the high prevalence of alcohol abuse among unemployed people is explained by alcohol abuse causing unemployment, or vice versa. A 5-year postal follow-up survey of a community sample of unemployed from Grenland, southern Norway. Two hundred and twenty-eight unemployed people, registered for more than 12 weeks, aged 16 to 63 years. Response rate 74%. The Alcohol Use Disorder Identification Test (AUDIT) and DSM-III diagnoses of alcohol disorders in medical examinations. At the 5-year follow up, 23% of those still unemployed and 12% of those re-employed scored higher than the AUDIT cut-point of 10. Re-employment reduced the chance of scoring positive on the AUDIT to 34% of the chance for those still unemployed. Significant selection to long-term unemployment according to AUDIT score was not demonstrated. None of the 7% who had a DSM-III diagnosis of an alcohol disorder had a job 5 years later, however, suggesting that alcohol-related selection to unemployment does occur. The high prevalence of harmful drinking among Norwegian unemployed is explained mainly by unemployment causing alcohol abuse rather than vice versa. Reducing unemployment should contribute to reduced alcohol problems in Norway.

Little is known about the genetic basis of convergent traits that originate repeatedly over broad taxonomic scales. The myogenic electric organ has evolved six times in fishes to produce electric fields used in communication, navigation, predation, or defense. We have examined the genomic basis of the convergent anatomical and physiological origins of these organs by assembling the genome of the electric eel (Electrophorus electricus) and sequencing electric organ and skeletal muscle transcriptomes from three lineages that have independently evolved electric organs. Our results indicate that, despite millions of years of evolution and large differences in the morphology of electric organ cells, independent lineages have leveraged similar transcription factors and developmental and cellular pathways in the evolution of electric organs.

While the effects of growth from birth to expected term on the subsequent development of preterm children has attracted plentiful attention, less is known about the effects of post-term growth. We aimed to delineate distinct patterns of post-term growth and to determine their association with the cognitive development of preterm children. Data from a prospective population-based cohort of 3,850 surviving infants born at less than 35 weeks of gestational age were used. Growth was assessed as the Body Mass Index (BMI) Z-scores at 3, 9, 18, 24, 36, 48, and 60 months. Cognitive development at five years of age was evaluated by the Global School Adaptation score (GSA). Latent class analysis was implemented to identify distinct growth patterns and logistic regressions based on propensity matching were used to evaluate the relationship between identified growth trajectories and cognitive development. Four patterns of post-term growth were identified: a normal group with a Z-score consistently around zero during childhood (n = 2,469; 64%); a group with an early rapid rise in the BMI Z-score, but only up to 2 years of age (n = 195; 5%); a group with a slow yet steady rise in the BMI Z-score during childhood (n = 510; 13%); and a group with a negative Z-score growth until 3 years of age (n = 676; 18%). The group with a slow yet steady rise in the BMI Z-score was significantly associated with low GSA scores. Our findings indicate heterogeneous post-term growth of preterm children, with potential for association with their cognitive development.

Evaluation of Chemistry-Climate Model Results using Long-Term Satellite and Ground-Based Data

NASA Technical Reports Server (NTRS)

Stolarski, Richard S.

2005-01-01

Chemistry-climate models attempt to bring together our best knowledge of the key processes that govern the composition of the atmosphere and its response to changes in forcing. We test these models on a process by process basis by comparing model results to data from many sources. A more difficult task is testing the model response to changes. One way to do this is to use the natural and anthropogenic experiments that have been done on the atmosphere and are continuing to be done. These include the volcanic eruptions of El Chichon and Pinatubo, the solar cycle, and the injection of chlorine and bromine from CFCs and methyl bromide. The test of the model's response to these experiments is their ability to produce the long-term variations in ozone and the trace gases that affect ozone. We now have more than 25 years of satellite ozone data. We have more than 15 years of satellite and ground-based data of HC1, HN03, and many other gases. I will discuss the testing of models using long-term satellite data sets, long-term measurements from the Network for Detection of Stratospheric Change (NDSC) , long-term ground-based measurements of ozone.

Long-term weather predictability: Ural case study

The accuracy of the state-of-the-art long-term meteorological forecast (at the seasonal level) is still low. Here it is presented approach (RAMES method) realizing different forecasting methodology. It provides prediction horizon of up to 19-22 years under equal probabilities of determination of parameters in every analyzed period [1]. Basic statements of the method are the following. 1. Long-term forecast on the basis of numerical modeling of the global meteorological process is principally impossible. Extension of long-term prediction horizon could be obtained only by the revealing and using a periodicity of meteorological situations at one point of observation. 2. Conventional calendar is unsuitable for generalization of meteorological data and revealing of cyclicity of meteorological processes. RAMES method uses natural time intervals: one day, synodic month and one year. It was developed a set of special calendars using these natural periods and the Metonic cycle. 3. Long-term time series of meteorological data is not a uniform universal set, it is a sequence of 28 universal sets appropriately superseding each other in time. The specifics of the method are: 1. Usage of the original research toolkit consisting of - a set of calendars based on the Metonic cycle; - a set of charts (coordinate systems) for the construction of sequence diagrams (of daily variability of a meteorological parameter during the analyzed year; of daily variability of a meteorological parameter using long-term dynamical time series of periods-analogues; of monthly and yearly variability of accumulated value of meteorological parameter). 2. Identification and usage of new virtual meteorological objects having several degrees of generalization appropriately located in the used coordinate systems. 3. All calculations are integrated into the single technological scheme providing comparison and mutual verification of calculation results. During the prolonged testing in the Ural region, it was

OBJECTIVE: To document long-term results associated with an coordinated plan of care for acutely burned hands in children. SUMMARY AND BACKGROUND DATA: Optimal hand function is a crucial component of a high-quality survival after burn injury. This can be achieved only with a coordinated approach to the injuries. Long-term outcomes associated with such a plan of care have not been previously reported. METHODS: Over a 10-year period, 495 children with 698 acutely burned hands were managed at a regional pediatric burn facility; 219 children with 395 injured hands were followed in the authors' outpatient clinic for at least 1 year and an average of >5 years. The authors' approach to the acutely burned hand emphasizes ranging and splinting throughout the hospital stay, prompt sheet autograft wound closure as soon as practical, and the selective use of axial pin fixation and flaps. Long-term follow-up, hand therapy, and reconstructive surgery are emphasized. RESULTS: Normal functional results were seen in 97% of second-degree and 85% of third-degree injuries; in children with burns involving underlying tendon and bone, 70% could perform activities of daily living and 20% had normal function. Reconstructive hand surgery was required in 4.4% of second-degree burns, 32% of third-degree burns, and 65% of those with injuries involving underlying bone and tendon. CONCLUSIONS: When managed in a coordinated long-term program, the large majority of children with serious hand burns can be expected to have excellent functional results. Images Figure 1. Figure 2.

A difficult birth at term (DBAT) may manifest as fetal acidosis and low Apgar scores and is often referred to as "perinatal asphyxia," especially when infants show signs of neonatal encephalopathy (NE). In contrast to DBAT resulting in moderate-to-severe NE, which is associated with neurodevelopmental disorders, little is known about the prognosis of less severe forms of DBAT, with or without NE. The purpose of this study was to evaluate the International Classification of Functioning, Disability and Health, Children & Youth Version activity "mobility" and other neurodevelopmental sequelae in infants with DBAT at age 6 years. The index cohort (n=62; 35 boys, 27 girls) consisted of consecutive term infants with DBAT based on clinical criteria in a Dutch nonacademic hospital from 1999 to 2005. Neonatal encephalopathy was assessed according to the Sarnat grading system and excluded infants with severe NE. The matched reference cohort (n=81; 49 boys, 32 girls) consisted of healthy term infants. The primary outcome at 6 years was limited mobility (Movement Assessment Battery for Children score ≤15th percentile). Secondary outcomes included learning and behavioral problems and the presence of minor neurological dysfunction. Three children developed cerebral palsy and were excluded from analyses. Children with DBAT more often had limited mobility than children without DBAT (risk ratio [RR]=2.44; 95% confidence interval [95% CI]=1.16, 5.14). The risk of limited mobility rose with increasing severity of NE (mild NE: RR=3.38; 95% CI=1.40, 8.16; moderate NE: RR=4.00; 95% CI=1.54, 10.40), and manual abilities especially were affected (RR=4.12; 95% CI=1.40, 12.14). Learning problems, need for physical therapy, and complex minor neurological dysfunction were more common in children with DBAT than in children without DBAT. Term infants who develop mild or moderate NE following DBAT are at increased risk for limited mobility at age 6 years. Routine monitoring of neuromotor

The scientific basis for patient blood management.

Patient blood management is an increasingly used term to describe an evidence-based, multidisciplinary approach to optimising the care of patients who might need transfusion. It encompasses measures to avoid transfusion such as anaemia management without transfusion, cell salvage and the use of anti-fibrinolytic drugs to reduce bleeding as well as restrictive transfusion. It ensures that patients receive the optimal treatment, and that avoidable, inappropriate use of blood and blood components is reduced. This paper provides an overview of the scientific basis for patient blood management with a focus on the increasing evidence for restrictive rather than liberal transfusion practice and the use of electronic blood ordering and decision support to facilitate its implementation.

This study evaluated the long-term effects of a Therapeutic Workplace social business on drug abstinence and employment. Pregnant and postpartum women (N=40) enrolled in methadone treatment were randomly assigned to a Therapeutic Workplace or Usual Care Control group. Therapeutic Workplace participants could work weekdays in training and then as employees of a social business, but were required to provide drug-free urine samples to work and maintain maximum pay. Three-year outcomes were reported previously. This paper reports 4- to 8- year outcomes. During year 4 when the business was open, Therapeutic Workplace participants provided significantly more cocaine- and opiate-negative urine samples than controls; reported more days employed, higher employment income, and less money spent on drugs. During the 3 years after the business closed, Therapeutic Workplace participants only reported higher income than controls. A Therapeutic Workplace social business can maintain long-term abstinence and employment, but additional intervention may be required to sustain effects. PMID:25124257

2008-01-01

The highly prevalent psychiatric disorders dysthymia and panic disorder have often a chronic or recurrent course with superimposed major depression. The prominent comorbidity between these diagnoses constitutes a confounding factor in the study of long-term outcome. We performed a 9-year follow-up of 38 patients with "pure" diagnoses, i.e. without comorbid dysthymia and panic disorder, selected from two 2-year naturalistic treatment studies with psychotherapy and antidepressant medication. The aims of the present study were to investigate 1) the stability of change, and 2) the impact of comorbid personality disorders (PDs) on long-term outcome. Patients were reassessed with SCID-I and SCID-II interviews, SCL-90/BSI and a detailed, modified life-charting interview, investigating course and treatment over time. About 50% of patients showed substantial improvement, of whom about half were in remission. Comorbid PD was a negative prognostic factor independently of Axis I diagnosis. Although patients with panic disorder had a lower frequency of comorbid PD, later onset, shorter duration of illness and better outcome after the original studies, there was no difference in the long-term outcome. The less stable outcome among panic patients suggests that standard treatments are not resulting in enduring remission. In order to achieve remission, it is necessary to 1) address comorbid PDs, 2) perform careful assessments of all comorbid diagnoses, and 3) build routines for the follow-up and augmentation of treatments.

Global Burden of Leptospirosis: Estimated in Terms of Disability Adjusted Life Years

Background Leptospirosis, a spirochaetal zoonosis, occurs in diverse epidemiological settings and affects vulnerable populations, such as rural subsistence farmers and urban slum dwellers. Although leptospirosis can cause life-threatening disease, there is no global burden of disease estimate in terms of Disability Adjusted Life Years (DALYs) available. Methodology/Principal Findings We utilised the results of a parallel publication that reported global estimates of morbidity and mortality due to leptospirosis. We estimated Years of Life Lost (YLLs) from age and gender stratified mortality rates. Years of Life with Disability (YLDs) were developed from a simple disease model indicating likely sequelae. DALYs were estimated from the sum of YLLs and YLDs. The study suggested that globally approximately 2·90 million DALYs are lost per annum (UIs 1·25–4·54 million) from the approximately annual 1·03 million cases reported previously. Males are predominantly affected with an estimated 2·33 million DALYs (UIs 0·98–3·69) or approximately 80% of the total burden. For comparison, this is over 70% of the global burden of cholera estimated by GBD 2010. Tropical regions of South and South-east Asia, Western Pacific, Central and South America, and Africa had the highest estimated leptospirosis disease burden. Conclusions/Significance Leptospirosis imparts a significant health burden worldwide, which approach or exceed those encountered for a number of other zoonotic and neglected tropical diseases. The study findings indicate that highest burden estimates occur in resource-poor tropical countries, which include regions of Africa where the burden of leptospirosis has been under-appreciated and possibly misallocated to other febrile illnesses such as malaria.

A New Dimension to Relative Age Effects: Constant Year Effects in German Youth Handball

Schorer, Jörg; Wattie, Nick; Baker, Joseph R.

2013-01-01

In this manuscript we argue for a broader use of the term ‘relative age effect’ due to the influence of varying development policies on the development of sport expertise. Two studies are presented on basis of data from Schorer, et al. [1]. The first showed clear ‘constant year effects’ in the German handball talent development system. A shift in year groupings for the female athletes resulted in a clear shift of birth year patterns. In the second study we investigated whether the constant year effect in the national talent development system carried over to professional handball. No patterns were observable. Together both studies show that a differentiation of varying effects that often happen simultaneously is necessary to understand the secondary mechanisms behind the development of sport expertise.

The aim of this study was to evaluate the long-term dental implant survival rates of Straumann dental implants in a university hospital environment over 12 to 23 years. A total of 388 Straumann dental implants with titanium-sprayed surfaces (TPS) were inserted in 92 patients between 1988 and 1999 in the Department of Oral and Maxillofacial Surgery of the University Hospital Schleswig-Holstein in Kiel, and they were reevaluated with standardized clinical and radiological exams. Kaplan-Meier analyses were performed for individual factors. Cox proportional hazard regression analysis was used to detect the factors influencing long-term implant failure. The long-term implant survival rate was 88.03% after an observation time of 12.2 to 23.5 years. Cox regression revealed statistically significant influences of the International Team for Implantology (ITI) implantation type (p = .00354) and tobacco smoking (p = .01264) on implant failure. A proportion 82.8% of the patients with implant losses had a medical history of periodontitis. Peri-implantitis was diagnosed in 9.7% of the remaining implants in the long-term survey. This study emphasized the long-term rehabilitation capabilities of Straumann dental implants in complex cases. The survival rates after several years constitute important information for patients, as well as for clinicians, in deciding about different concepts of tooth replacement. Patient-related and technical factors - determined before implant placement - could help to predict the risk of implant loss. © 2015 Wiley Periodicals, Inc.

Long-term microparticle flux variability indicated by comparison of Interplanetary Dust Experiment (IDE) timed impacts for LDEF's first year in orbit with impact data for the entire 5.77-year orbital lifetime

The electronic sensors of the Interplanetary Dust Experiment (IDE) recorded precise impact times and approximate directions for submicron to approximately 100 micron size particles on all six primary sides of the spacecraft for the first 346 days of the LDEF orbital mission. Previously-reported analyses of the timed impact data have established their spatio-temporal features, including the demonstration that a preponderance of the particles in this regime are orbital debris and that a large fraction of the debris particles are encountered in megameter-size clouds. Short-term fluxes within such clouds can rise several orders of magnitude above the long-term average. These unexpectedly large short-term variations in debris flux raise the question of how representative an indication of the multi-year average flux is given by the nearly one year of timed data. One of the goals of the IDE was to conduct an optical survey of impact sites on detectors that remained active during the entire LDEF mission, to obtain full-mission fluxes. We present here the comparisons and contrasts among the new IDE optical survey impact data, the IDE first-year timed impact data, and impact data from other LDEF micrometeoroid and debris experiments. The following observations are reported: (1) the 5.77 year long-term integrated microparticle impact fluxes recorded by IDE detectors matched the integrated impact fluxes measured by other LDEF investigators for the same period; (2) IDE integrated microparticle impact fluxes varied by factors from 0.5 to 8.3 for LDEF days 1-346, 347-2106 and 1-2106 (5.77 years) on rows 3 (trailing edge, or West), 6 (South side), 12 (North side), and the Earth and Space ends; and (3) IDE integrated microparticle impact fluxes varied less than 3 percent for LDEF days 1-346, 347-2106 and 1-2106 (5.77 years) on row 9 (leading edge, or East). These results give further evidence of the accuracy and internal consistency of the recorded IDE impact data. This leads to

The objective of this study was to evaluate the mid-term migration pattern of a femoral short stem. Implant migration of 73 femoral short-stems was assessed by Ein-Bild-Roentgen-Analysis Femoral-Component-Analysis (EBRA-FCA) 5 years after surgery. Migration pattern of the whole group was analysed and compared to the migration pattern of implants "at risk" with a subsidence of more than 1.5 mm 2 years postoperative. Mean axial subsidence was 1.1 mm (-5.0 mm to 1.5 mm) after 60 months. There was a statistical significant axial migration until 2 years postoperative with settling thereafter. 2 years after surgery 18 of 73 Implants were classified "at risk." Nevertheless, all stems showed secondary stabilisation in the following period with no implant failure neither in the group of implants with early stabilisation nor the group with extensive early onset migration. In summary, even in the group of stems with more pronounced early subsidence, delayed settling occurred in all cases. The determination of a threshold of critical early femoral short stem subsidence is necessary because of the differing migration pattern described in this study with delayed settling of the Fitmore stem 2 years postoperatively compared to early settling within the first postoperative year described for conventional stems.

Testicular cancer has become the paradigm of adult-onset cancer survivorship, due to the young age at diagnosis and 10-year relative survival of 95%. This clinical review presents the current status of various treatment-related complications experienced by long-term testicular cancer survivors (TCS) free of disease for 5 or more years after primary treatment. Cardiovascular disease and second malignant neoplasms represent the most common potentially life-threatening late effects. Other long-term adverse outcomes include neuro- and ototoxicity, pulmonary complications, nephrotoxicity, hypogonadism, infertility, and avascular necrosis. Future research efforts should focus on delineation of the genetic underpinning of these long-term toxicities to understand their biologic basis and etiopathogenetic pathways, with the goal of developing targeted prevention and intervention strategies to optimize risk-based care and minimize chronic morbidities. In the interim, health care providers should advise TCS to adhere to national guidelines for the management of cardiovascular disease risk factors, as well as to adopt behaviors consistent with a healthy lifestyle, including smoking cessation, a balanced diet, and a moderate to vigorous intensity exercise program. TCS should also follow national guidelines for cancer screening as currently applied to the general population. PMID:29670654

Adjective semantics, world knowledge and visual context: comprehension of size terms by 2- to 7-year-old Dutch-speaking children.

PubMed

Tribushinina, Elena

2013-06-01

The interpretation of size terms involves constructing contextually-relevant reference points by combining visual cues with knowledge of typical object sizes. This study aims to establish at what age children learn to integrate these two sources of information in the interpretation process and tests comprehension of the Dutch adjectives groot 'big' and klein 'small' by 2- to 7-year-old children. The results demonstrate that there is a gradual increase in the ability to inhibit visual cues and to use world knowledge for interpreting size terms. 2- and 3-year-old children only used the extremes of the perceptual range as reference points. From age four onwards children, like adults, used a cut-off point in the mid-zone of a series. From age five on, children were able to integrate world knowledge and perceptual context. Although 7-year-olds could make subtle distinctions between sizes of various object classes, their performance on incongruent items was not yet adult-like.

Radical pelvic exenteration can be undertaken for locally invasive or recurrent disease in both colorectal and gynaecological malignancies. In the UK this procedure is usually undertaken by the respective surgical specialties who have undergone divergent surgical training. This study describes and compares outcomes between colorectal and gynae-oncological teams following pelvic exenteration for primary and recurrent gynaecological and colorectal cancers in a single-centre multi-disciplinary team. A retrospective review of consecutive pelvic exenteration patients undertaken over a nine-year period in a tertiary referral centre. Analyses comparing short- and long-term morbidity and mortality outcomes were undertaken by chi-square test for categorical variables and Mann-Whitney U for continuous variables. Cumulative survival rates were calculated according to the Kaplan-Meier method and factors associated with recurrence and survival determined using a Cox regression model. Thirty-four exenterations were undertaken; fourteen colorectal and twenty gynae-oncological. Morbidity was seen in 50% of colorectal and 75% of gynae-oncological patients. Recurrence was seen earlier and with greater frequency in the gynaeoncology group (44.4% and median time 11 months) than the colorectal group (21.4%, median time 41 months; p > 0.05). Survival in the gynae-oncology group was also lower than the colorectal group at 1-year (69.6% vs. 92.9%) and 5-years (58.0% vs. 92.9%; p = 0.115). The majority of gynae-oncological mortality occurred within 3-years of surgery, whilst the majority of mortality in the colorectal group was after 5-years. Long-term patient outcome measures, including disease recurrence and 5-year survival, for colorectal exenteration appear better than for gynaeoncology patients, however, no statistical significant difference exists between short-term outcome measures between specialties. This is likely to be caused by different baseline pathologies and disease

Background: In coupled-channels models the poles of the scattering S matrix are located on different Riemann sheets. Physical observables are affected mainly by poles closest to the physical region but sometimes shadow poles have considerable effect too. Purpose: The purpose of this paper is to show that in coupled-channels problems all poles of the S matrix can be located by an expansion in terms of a properly constructed complex-energy basis. Method: The Berggren basis is used for expanding the coupled-channels solutions. Results: The locations of the poles of the S matrix for the Cox potential, constructed for coupled-channels problems, were numerically calculated and compared with the exact ones. In a nuclear physics application the Jπ=3 /2+ resonant poles of 5He were calculated in a phenomenological two-channel model. The properties of both the normal and shadow resonances agree with previous findings. Conclusions: We have shown that, with an appropriately chosen Berggren basis, all poles of the S matrix including the shadow poles can be determined. We have found that the shadow pole of 5He migrates between Riemann sheets if the coupling strength is varied.

We report short and long-term results with the dedicated Synthes(®) titanium plates system, introduced 5 years ago, for chest wall stabilization and reconstruction. We retrospectively analyzed (January 2010 to December 2014) 27 consecutive patients (22 males, 5 females; range 16-83 years, median age 60 years), treated with this system: primary [3] and secondary [8] chest wall tumor; flail chest [5]; multiple ribs fractures [5]; sternal dehiscence-diastasis [3]; sternal fracture [1]; sternoclavicular joint dislocation [1]; Poland syndrome [1]. Short-term results were evaluated as: operating time, post-operative morbidity, mortality, hospital stay; long-term results as: survival, plates-related morbidity, spirometric values, chest pain [measured with Verbal Rating Scale (VRS) and SF12 standard V1 questionnaire]. Each patient received from 1 to 10 (median 2) titanium plates/splints; median operating time was 150 min (range: 115-430 min). Post-operative course: 15 patients (55.6%) uneventful, 10 (37%) minor complications, 2 (7.4%) major complications; no post-operative mortality. Median post-operative hospital stay was 13 days (range: 5-129 days). At a median follow-up of 20 months (range: 1-59 months), 21 patients (78%) were alive, 6 (22%) died. Three patients presented long-term plates-related morbidity: plates rupture [2], pin plate dislodgment [1]; two required a second surgical look. One-year from surgery median spirometric values were: FVC 3.31 L (90%), FEV1 2.46 L (78%), DLCO 20.9 mL/mmHg/min (76%). On 21 alive patients, 7 (33.3%) reported no pain (VRS score 0), 10 (47.6%) mild (score 2), 4 (19.1%) moderate (score 4), no-one severe (score >4); 15 (71.5%) reported none or mild, 6 (28.5%) moderate pain influencing quality of life. An optimal chest wall stabilization and reconstruction was achieved with the Synthes(®) titanium plates system, with minimal morbidity, no post-operative mortality, acceptable operating time and post-operative hospital stay.

The paper investigates bounds failure in calculations using Gaussian basis sets for the solution of the one-electron Dirac equation for the 2p1/2 state of Hg(79+). It is shown that bounds failure indicates inadequacies in the basis set, both in terms of the exponent range and the number of functions. It is also shown that overrepresentation of the small component space may lead to unphysical results. It is concluded that it is important to use matched large and small component basis sets with an adequate size and exponent range.

To describe the long-term effects of infertility on life and partnership satisfaction. Longitudinal cohort study. A university outpatient andrology and gynecology infertility clinic. 275 men and 272 women treated for infertility between August 2000 and December 2001. None. The Life Satisfaction Questionnaire (FLZ), the Partnership Questionnaire (PFB), and sociodemographic items at baseline (T1) and 5 years later (T2). Compared with a representative sample, our male and female participants had higher Finance and Partnership scores and lower Health scores on the FLZ at T1. They also had markedly higher PFB scores, with the exception of Conflict Behavior. After 5 years (T2), 101 men and 113 women rated the Partnership and Sexuality FLZ subscales as well as all the PFB subscales statistically significantly lower than at baseline. Only the women rated the Self-esteem FLZ subscale lower than at baseline (T1). Participants who became parents had lower Leisure and Partnership FLZ subscale scores, and fathers had lower Finance FLZ subscale scores. Satisfaction declined over 5 years for both men and women, but only in the partnership-related domains. Women were more affected than men. The success of infertility treatment had only a minor influence on a couple's future satisfaction. Copyright © 2011. Published by Elsevier Inc.

Medium-term outcomes and complications after total replacement of the temporomandibular joint. Prospective outcome analysis after 3 and 5 years.

In this prospective analysis, we assess the medium-term benefits, efficacy, and safety of the TMJ Concepts joint replacement system in the United Kingdom. Outcome measures of pain, maximum mouth opening, and diet were recorded preoperatively and at intervals up to 3 and 5 years. All patients who had replacement temporomandibular joints (TMJ) within a 6-year period were included. A total of 58 patients (84 joints) were followed up for 3 years (mean age 47, range 19-72) and 26 (42 joints) for 5 years (mean age 46, range 27-70). The female to male ratio was 52:6 at 3 years and 23:3 at 5 years. The most common diagnosis was degenerative disease, and the mean number of previous TMJ procedures was 2.4 (range 0-14). There were significant improvements in pain scores (7.4 reduced to 0.6 at 3 years and 0.8 at 5 years), maximum mouth opening (21.0-35.5mm at 3 years and 23.8-33.7mm at 5 years), and dietary scores (4.1-9.7 at 3 years and 3.7-9.6 at 5 years). Revision operations were required in 2 patients (not included in the outcome data) for biofilm infection of the prosthesis secondary to local infection in the head and neck. One patient had weakness of the temporal branch of the facial nerve that needed correction. TMJ replacement is an effective form of management for an irreparably damaged joint, particularly in cases of ankylosis. It lessens pain and improves function with minimal long-term morbidity.

Spatial scaling is a critical issue in ecology, but how anthropogenic activities like fertilization affect spatial scaling is poorly understood, especially for microbial communities. Here, we determined the effects of long-term fertilization on the spatial scaling of microbial functional diversity and its relationships to plant diversity in the 150-year-old Park Grass Experiment, the oldest continuous grassland experiment in the world. Nested samples were taken from plots with contrasting inorganic fertilization regimes, and community DNAs were analyzed using the GeoChip-based functional gene array. The slopes of microbial gene-area relationships (GARs) and plant species-area relationships (SARs) were estimated in a plot receivingmore » nitrogen (N), phosphorus (P), and potassium (K) and a control plot without fertilization. Our results indicated that long-term inorganic fertilization significantly increased both microbial GARs and plant SARs. Microbial spatial turnover rates (i.e., z values) were less than 0.1 and were significantly higher in the fertilized plot (0.0583) than in the control plot (0.0449) (P < 0.0001). The z values also varied significantly with different functional genes involved in carbon (C), N, P, and sulfur (S) cycling and with various phylogenetic groups (archaea, bacteria, and fungi). Similarly, the plant SARs increased significantly (P < 0.0001), from 0.225 in the control plot to 0.419 in the fertilized plot. Soil fertilization, plant diversity, and spatial distance had roughly equal contributions in shaping the microbial functional community structure, while soil geochemical variables contributed less. These results indicated that long-term agricultural practice could alter the spatial scaling of microbial biodiversity.

Heavy snoring and the obstructive sleep apnea syndrome are associated with increased morbidity and mortality in patients with cardiovascular disease. The effect of uvulopalatopharyngoplasty on mortality has been questioned. To investigate long-term survival after palatal surgery. An observational retrospective case-control study with a 5- to 9-year follow-up. A university medical center. Four hundred consecutive heavy snorers (median age, 47 years), 256 of whom had obstructive sleep apnea syndrome. The mean +/- SD body mass index (calculated as weight in kilograms divided by the square of height in meters) of all included patients was 27.1+/-4.2. Comparison was made with 744 control patients (median age, 43 years) who underwent nasal surgery during the same period and a matched general control population. Uvulopalatopharyngoplasty or laser uvulopalatoplasty between 1986 and 1990. Mortality and causes of death up to 9 years after surgery. High blood pressure at the time of surgery and subsequent death due to cardiovascular disease were 3 times more frequent in the patients with obstructive sleep apnea syndrome than in both control groups (P<.01), but the overall long-term mortality was not increased either in snorers or in persons with sleep apnea. The cumulative survival rate was more than 96% for the 400 patients, the 744 controls, and the matched general population. No increased mortality was seen following palatal surgery in this long-term follow-up of 400 consecutive, on average, nonobese snorers, 256 of whom had obstructive sleep apnea syndrome. This might indicate a positive survival effect of surgery.

Calculating vibrational spectra with sum of product basis functions without storing full-dimensional vectors or matrices.

PubMed

Leclerc, Arnaud; Carrington, Tucker

2014-05-07

We propose an iterative method for computing vibrational spectra that significantly reduces the memory cost of calculations. It uses a direct product primitive basis, but does not require storing vectors with as many components as there are product basis functions. Wavefunctions are represented in a basis each of whose functions is a sum of products (SOP) and the factorizable structure of the Hamiltonian is exploited. If the factors of the SOP basis functions are properly chosen, wavefunctions are linear combinations of a small number of SOP basis functions. The SOP basis functions are generated using a shifted block power method. The factors are refined with a rank reduction algorithm to cap the number of terms in a SOP basis function. The ideas are tested on a 20-D model Hamiltonian and a realistic CH3CN (12 dimensional) potential. For the 20-D problem, to use a standard direct product iterative approach one would need to store vectors with about 10(20) components and would hence require about 8 × 10(11) GB. With the approach of this paper only 1 GB of memory is necessary. Results for CH3CN agree well with those of a previous calculation on the same potential.

To investigate the long-term effectiveness of a school-based intervention to improve physical activity and diet in children. Cluster-randomised controlled trial. 60 primary schools in the southwest of England. Primary school children who were aged 8-9 years at recruitment, 9-10 years during the intervention and 10-11 years at the long-term follow-up assessment. Teacher training, provision of lesson and child-parent interactive homework plans and teaching materials. Primary outcomes were accelerometer-assessed minutes of moderate to vigorous physical activity (MVPA) per day, accelerometer-assessed minutes of sedentary behaviour per day and reported daily consumption of servings of fruit and vegetables. 60 schools with 2221 eligible children were recruited. As in the previously published assessment immediately after the end of the intervention, none of the three primary outcomes differed between children in schools allocated to the intervention, compared with those in control schools at the end of the long-term follow-up (1 year after the end of the intervention). Differences in secondary outcomes were consistent with those at the immediate follow-up, with no evidence that these had diminished over time. Comparing intervention with control schools, the difference in mean child-reported screen viewing at the weekend was -16.03 min (95% CI -32.82 to 0.73), for servings of snacks per day, the difference was -0.11 (95% CI -0.39 to 0.06), in servings of high-energy drinks per day -0.20 (95% CI -0.39 to -0.01) and in servings of high-fat foods per day -0.12 (95% CI -0.39 to 0.00). None of these reached our predefined level of statistical significance, especially after accounting for multiple testing. School-based curriculum interventions alone are unlikely to have a major public health impact on children's diet and physical activity. ISRCTN50133740, Post-results.

To investigate the relation between head growth at different periods and IQ at 8 years, and to identify factors associated with more rapid head growth. Two parallel cohorts of term low birthweight (LBW) and appropriate birthweight (ABW) infants were enrolled at birth in northeast Brazil. Anthropometric measurements were made at birth, 2 months, 6 months, 12 months, 24 months, and 8 years. Cognition was assessed at 8 years (n=164) with the Wechsler Intelligence Scale for Children. Multivariable analysis with a two-stage residual model was used to relate head growth between successive time points with IQ. Mean birthweight was 2.35kg (SD 0.15) in the LBW group (33 males, 50 females), and 3.21kg (SD 0.15) in the ABW group (28 males, 53 females). Mean gestational age was 38.8 weeks (SD 1.4) and 40.0 weeks (SD 1.3) respectively. In the LBW group, head growth from birth to 2 months and from 2 to 6 months, conditional on previous size, were significant independent predictors of IQ at 8 years. Conditional head growth from 6 months to 8 years and head size at birth were unrelated to IQ. In the ABW group there was no significant relation between conditional head growth and IQ for any period. Determinants of more rapid head growth from birth to 6 months in LBW infants were maternal height and rate of infant weight gain. Head growth from birth to 6 months in term LBW infants is more important than prenatal or later postnatal head growth in predicting IQ at 8 years.

Purpose To report on the long-term results of a randomized trial comparing a standard dose (400 mg/d) versus a higher dose (800 mg/d) of imatinib in patients with metastatic or locally advanced GI stromal tumors (GISTs). Patients and Methods Eligible patients with advanced CD117-positive GIST from 56 institutions in 13 countries were randomly assigned to receive either imatinib 400 mg or 800 mg daily. Patients on the 400-mg arm were allowed to cross over to 800 mg upon progression. Results Between February 2001 and February 2002, 946 patients were accrued. Median age was 60 years (range, 18 to 91 years). Median follow-up time was 10.9 years. Median progression-free survival times were 1.7 and 2.0 years in the 400- and 800-mg arms, respectively (hazard ratio, 0.91; P = .18), and median overall survival time was 3.9 years in both treatment arms. The estimated 10-year progression-free survival rates were 9.5% and 9.2% for the 400- and 800-mg arms, respectively, and the estimated 10-year overall survival rates were 19.4% and 21.5%, respectively. At multivariable analysis, age (< 60 years), performance status (0 v ≥ 1), size of the largest lesion (smaller), and KIT mutation (exon 11) were significant prognostic factors for the probability of surviving beyond 10 years. Conclusion This trial was carried out on a worldwide intergroup basis, at the beginning of the learning curve of the use of imatinib, in a large population of patients with advanced GIST. With a long follow-up, 6% of patients are long-term progression free and 13% are survivors. Among clinical prognostic factors, only performance status, KIT mutation, and size of largest lesion predicted long-term outcome, likely pointing to a lower burden of disease. Genomic and/or immune profiling could help understand long-term survivorship. Addressing secondary resistance remains a therapeutic challenge.

Missions in space within the next two decades will be of longer duration than those carried out up to the present time, and the effects of such long-term flights on biological organisms are unknown. Results of biological experiments that have been performed to date cannot be extrapolated to results in future flights because of the unknown influence of adaptation over a long period of time. Prior experiments with Axolotl, fishes, and vertebrates by our research team (in part with sounding rockets) showed that these specimens did not appear to be suitable for long-term missions on which minimization of expense, technique, and energy is required. Subsequent investigations have shown the suitability of the leech (Hirudo medicinalis), which consumes blood of mammals up to ten times its own weight (1 g) and can live more than 2 years without further food supply. Emphasis in the experiments with Hirudo medicinalis is placed on metabolic rhythm and motility. Resorption and diffusion in tissue, development, and growth under long-term effects of cosmic proton radiation and zero-gravity are other focal points. The constancy of cellular life in the mature animals is a point in favor of these specimens. We have also taken into account the synergistic effects of the space environment on the problems just mentioned. The life-support system constructed for the leech has been tested successfully in four sounding rocket flights and, on that basis, has been prepared for a long-term mission. Long-term investigations out of the terrestrial biosphere will provide us with information concerning the degree of adaptation of certain physiological and biochemical functions and as to what extent biological readjustment or repair processes can occur under the specific stress conditions of space flight.

Long-term effectiveness of mailed nicotine replacement therapy: study protocol of a randomized controlled trial 5-year follow-up.

Our group recently completed a randomized controlled trial, evaluating the efficacy of providing 5 weeks of free nicotine replacement therapy (NRT; in the form of the nicotine patch) by expedited postal mail without behavioral assistance to regular adult smokers interested in receiving it. The findings revealed that mailed provision of nicotine patches resulted in more than a doubling of quit rates at a six-month follow-up compared to a no intervention control group. While this trial provided evidence for the effectiveness of mailed nicotine patches in promoting cessation, the findings speak only to the short term effectiveness of this approach. As relapse to smoking is known to occur beyond the 6 month period, it is important to evaluate whether the net benefit of NRT in naturalistic settings can be maintained long-term. The present study aims to perform a 5-year follow-up survey of participants in the original trial to evaluate the long-term effectiveness of mailed NRT. Trained interviewers will contact participants in the randomized controlled trial 5 years post-enrollment. A total of 924 participants will be eligible to be contacted. Interviewers will first assess participants' smoking status and their level of nicotine dependence. Participants reporting not currently smoking will be asked whether they have smoked tobacco, even a puff, in the last 30 days (primary outcome measure: 30-day point prevalence abstinence), past 6 months (secondary outcome measure: prolonged 6-month abstinence), and since the 8-week follow-up survey (secondary outcome measure: > 4 year continuous abstinence). Interviewers will be blind to experimental condition at the time the primary outcome measure will be assessed. It is hypothesized that participants who received nicotine patches at baseline will display significantly higher quit rates at the 5-year follow-up as compared to participants who did not receive nicotine patches at baseline. If the study finds that the mailed

Little is known about the expected treatment outcomes of patients with co-occurring schizophrenic and substance use disorders. This paper reports 3-year outcomes for 152 patients with schizophrenia or schizoaffective disorder and substance use disorders, all of whom received integrated dual disorders treatments in the New Hampshire Dual Diagnosis Study. Outcomes are defined as positive coping behaviors identified by consumers as indicators of recovery. Participants improved steadily in terms of controlling symptoms of schizophrenia, actively attaining remissions from substance abuse, increasing competitive employment, increasing social contacts with non-substance abusers, and improving life satisfaction. Though successful in reducing hospitalization and homelessness, they did not increase time in independent living situations. Outcomes were only weakly interrelated, suggesting that recovery is a multidimensional concept. Neither psychotic diagnosis (schizophrenia vs. schizoaffective disorder) nor substance abuse diagnosis (alcohol vs. other drug disorder vs. both) was related to outcomes. However, these patients with co-occurring schizophrenic and substance use disorders did significantly less well than patients with co-occurring bipolar and substance use disorders in terms of hospitalization, independent living, and quality of life. Overall, the findings provide a hopeful long-term perspective for dual diagnosis patients.

To date, there is a lack of long-term safety and efficacy data for iron chelation therapy in transfusion-dependent patients with sickle cell disease (SCD). To evaluate the long-term safety and efficacy of deferasirox (a once-daily oral iron chelator), patients with SCD completing a 1-year, Phase II, randomized, deferoxamine (DFO)-controlled study entered a 4-year extension, continuing to receive deferasirox, or switching from DFO to deferasirox. Average actual deferasirox dose was 19·4 ± 6·3 mg/kg per d. Of 185 patients who received at least one deferasirox dose, 33·5% completed the 5-year study. The most common reasons for discontinuation were withdrawal of consent (23·8%), lost to follow-up (9·2%) and adverse events (AEs) (7·6%). Investigator-assessed drug-related AEs were predominantly gastrointestinal [including nausea (14·6%), diarrhoea (10·8%)], mild-to-moderate and transient in nature. Creatinine clearance remained within the normal range throughout the study. Despite conservative initial dosing, serum ferritin levels in patients with ≥ 4 years deferasirox exposure significantly decreased by -591 μg/l (95% confidence intervals, -1411, -280 μg/l; P = 0·027; n = 67). Long-term deferasirox treatment for up to 5 years had a clinically acceptable safety profile, including maintenance of normal renal function, in patients with SCD. Iron burden was substantially reduced with appropriate dosing in patients treated for at least 4 years. © 2011 Blackwell Publishing Ltd.

Short-term Outcomes following Concussion in the NFL: An 11-year Retrospective Study of Player Release Rate and Financial Loss

PubMed Central

Ramkumar, Prem; Navarro, Sergio Michael

2017-01-01

Objectives: The primary goal of this study was to assess the short-term outcomes among National Football League (NFL) players following concussion in terms of: (1) DNP protocol activation, (2) release rate at one and three years, and (3) mean salary reduction. A secondary goal of the study was to stratify the post-concussive release rate by franchise and player position. Methods: NFL player transaction records and publicly available weekly injury reports from August 2005 to January 2016 for NFL players were analyzed. All players immediately sustaining recorded concussions were evaluated for a change to inactive or do-not-play (DNP) status. The one-year and three-year release rate following concussion was defined as any player transitioning to inactivation, retirement, free agency, or any failure to return for a successive season on the same team’s active roster after one or three years from the initial concussion. Student’s t-test was used to compare release rates between non-concussed and concussed players at one and three years. Mean salary reduction per year following concussion was calculated using publicly available player contracts. Additionally, franchise-level and position-based analyses of the release rate were performed. Results: Of the total 5,451 NFL players retrospectively analyzed over the 11-year period, 373 sustained publicly reported concussions resulting in DNP protocol activation. The release rate of the post-concussive versus non-concussive player was 26% vs. 20% at 1 year (p<0.01) and 31% vs. 19% at 3 years (p<0.01). After analyzing individual player contracts, the mean year-over-year change in contract value for concussed players after DNP protocol activation was an overall salary reduction of $760,000/year ± $2,380,000. Figure 1 depicts the tendency of each NFL franchise to release an athlete following concussion within one and three years.

There is limited knowledge of the long-term medical consequences for children injured in car crashes. Thus, in the event of injury, the aim of the study was to specify patterns and risks of injuries resulting in permanent medical impairment of children (0-12 years) for different body regions and injury severity levels, according to Abbreviated Injury Scale (AIS). The aim was also to compare the impairment outcome with adults. Data were obtained from the Folksam insurance company, including reported car crashes from 1998 to 2010 with at least one injured child 0-12 years of age. In all, 2619 injured children with 3704 reported medical diagnoses were identified. All injuries were classified according to the AIS 2005 revision. If the child had not recovered within 1 year postinjury an assessment of permanent medical impairment (PMI) was made by one or several medical specialists. In all, 55 children sustained 59 injuries resulting in PMI of which 75 percent were at AIS 1 or AIS 2. The head and cervical spine were the body regions sustaining the most injuries resulting in PMI. Sixty-eight percent of all injuries resulting in PMI were AIS 1 injuries to the cervical spine, with the majority occurring in frontal or rear impacts. Given an injury to the cervical spine, the risk of injuries resulting in PMI was 3 percent, and older children (≥6 years) had a significantly higher risk (3% versus 1%) than younger children. The head was the second most commonly injured body region with injuries resulting in PMI (12/59), which were predominantly AIS 2+. In addition, mild traumatic brain injuries at AIS 1 were found to lead to PMI. Whereas for children the injuries leading to PMI were primarily limited to the head and cervical spine, adults sustained injuries that led to PMI from a more diverse distribution of body regions. The pattern of injuries resulting in permanent medical impairment is different for children and adults; therefore, safety priorities for children need to be

Interstitial lung disease (ILD) is highly prevalent in patients with mixed connective tissue disease (MCTD). However, little is known about the long-term progression of ILD in MCTD. The aims of this study were to describe pulmonary function test (PFT) and high-resolution computed tomography (HRCT) results in long-term MCTD patients, to measure changes in PFT and HRCT results over a 10-year period, and to ascertain correlations in functional and imaging data. In this retrospective cohort study, comparison between baseline and follow-up PFT and HRCT data was performed for 39 unselected consecutive MCTD patients. At baseline, 51% of the patients had abnormal PFTs. Forced vital capacity (FVC) was slightly reduced at baseline (77% of predicted), but remained stable after 10 years. A relative decrease of 15% in the diffusion capacity for carbon monoxide (DLCO) was detected (from 84% to 71% of predicted, p<0.001). The median lower lobes ILD-HRCT score progressed from 7.5% at baseline to 11.2% at follow-up (p=0.02), and findings of traction bronchiolectasis and honeycombing increased (p<0.05). A moderate negative correlation was observed between functional parameters and quantification of image findings. Functional and radiologic alterations suggestive of ILD in long-term MCTD patients are prevalent, mild, and progressed slightly over time. The most sensitive parameters for detecting subtle progression of ILD in MCTD patients are trends in DLCO, quantification of lower-lobes disease by HRCT (lower-lobes %ILD-HRCT score), and qualitative analysis of HRCT imaging.

Ontogeny of memory: An update on 40 years of work on infantile amnesia.

Madsen, Heather Bronwyn; Kim, Jee Hyun

Given the profound influence that early life experiences can have upon psychosocial functioning later in life, it is intriguing that most adults fail to recall autobiographical events from their early childhood years. Infantile amnesia is the term used to describe this phenomenon of accelerated forgetting during infancy, and it is not unique to humans. Over the years, information garnered from animal studies has provided clues as to the neurobiological basis of infantile amnesia. The purpose of this review is to provide a neurobiological update on what we now know about infantile amnesia since the publication of Campbell and Spear's seminal review on the topic more than 40 years ago. We present evidence that infantile amnesia is unlikely to be explained by a unitary theory, with the protracted development of multiple brain regions and neurotransmitter systems important for learning and memory likely to be involved. The recent discovery that exposure to early life stress can alleviate infantile amnesia offers a potential explanation as to how early adversity can so profoundly affect mental health in adulthood, and understanding the neurobiological basis for this early transition may lead to the development of effective therapeutic interventions.

2014-12-01

We propose a dynamical model that represents a process of deductive inference. We discuss the stability of logic dynamics and a neural basis for the dynamics. We propose a new concept of descriptive stability, thereby enabling a structure of stable descriptions of mathematical models concerning dynamic phenomena to be clarified. The present theory is based on the wider and deeper thoughts of John S. Nicolis. In particular, it is based on our joint paper on the chaos theory of human short-term memories with a magic number of seven plus or minus two.

To compare the short and long term results of different techniques of compression sclerotherapy. In the past 10 years the authors treated 1622 pts due to chronic venous insufficiency. There were 3 groups of patients: 1) Pts treated by Sigg's technique using Aethoxysclerol, 2) Pts treated by Fegan's technique with Fibrovein, and 3) Pts treated by Fegan's procedure, but using a combination of both sclerosants. In all cases, the techniques of empty vein, bubble air, uninterrupted 6-week compression and forced mobilisation were used. In the group of pats. treated by Sigg's procedure, the average cure rate was 67.47% after 6 months, 60.3% after 5 years of follow-up. In Fegan's group this rate was 83.6% after 6 months and 78.54% after 5 year assessment. Statistically, significant differences were found only by the disappearance of varices and reduction of pain in favour of Fegan's technique. In the group of pts treated by Fegan's (Aethoxysclerol + Fibrovein) this rate after 5 years was 86%. The only statistically significant difference was found by the disappearance of varices in favour of Fegan's technique using a combination of 2 detergent sclerosants. Sclerotherapy is effective when properly executed in any length of vein no matter how dilated it has become. The recurrences are attributed more to inadequate technique than to the shortcoming of the procedure. Sclerotherapy is miniinvasive, with few complications, and can be repeated on out-patient basis.

This study examined profiles of nonresidential father engagement (i.e., support to the adolescent, contact frequency, remarriage, relocation, and interparental conflict) with their adolescent children (N = 156) 6 to 8 years following divorce and the prospective relation between these profiles and the psychosocial functioning of their offspring, 9 years later. Parental divorce occurred during late childhood to early adolescence; indicators of nonresidential father engagement were assessed during adolescence, and mental health problems and academic achievement of offspring were assessed 9 years later in young adulthood. Three profiles of father engagement were identified in our sample of mainly White, non-Hispanic divorced fathers: Moderate Involvement/Low Conflict, Low Involvement/Moderate Conflict, and High Involvement/High Conflict. Profiles differentially predicted offspring outcomes 9 years later when they were young adults, controlling for quality of the mother-adolescent relationship, mother's remarriage, mother's income, and gender, age, and offspring mental health problems in adolescence. Offspring of fathers characterized as Moderate Involvement/Low Conflict had the highest academic achievement and the lowest number of externalizing problems 9 years later compared to offspring whose fathers had profiles indicating either the highest or lowest levels of involvement but higher levels of conflict. Results indicate that greater paternal psychosocial support and more frequent father-adolescent contact do not outweigh the negative impact of interparental conflict on youth outcomes in the long term. Implications of findings for policy and intervention are discussed.

Long-term record of Barents Sea Ice Sheet advance to the shelf edge from a 140,000 year record

The full-glacial extent and deglacial behaviour of marine-based ice sheets, such as the Barents Sea Ice Sheet, is well documented since the Last Glacial Maximum about 20,000 years ago. However, reworking of older sea-floor sediments and landforms during repeated Quaternary advances across the shelf typically obscures their longer-term behaviour, which hampers our understanding. Here, we provide the first detailed long-term record of Barents Sea Ice Sheet advances, using the timing of debris-flows on the Bear Island Trough-Mouth Fan. Ice advanced to the shelf edge during four distinct periods over the last 140,000 years. By far the largest sediment volumes were delivered during the oldest advance more than 128,000 years ago. Later advances occurred from 68,000 to 60,000, 39,400 to 36,000 and 26,000 to 20,900 years before present. The debris-flows indicate that the dynamics of the Saalian and the Weichselian Barents Sea Ice Sheet were very different. The repeated ice advance and retreat cycles during the Weichselian were shorter lived than those seen in the Saalian. Sediment composition shows the configuration of the ice sheet was also different between the two glacial periods, implying that the ice feeding the Bear Island Ice stream came predominantly from Scandinavia during the Saalian, whilst it drained more ice from east of Svalbard during the Weichselian.

Long-term particle flux variability indicated by comparison of Interplanetary Dust Experiment (IDE) timed impacts for LDEF's first year in orbit with impact data for the entire 5.75-year orbital lifetime

The electronic sensors of the Interplanetary Dust Experiment (IDE) recorded precise impact times and approximate directions for submicron to approximately 100-micron size particles on all six primary sides of the spacecraft for the first 346 days of the Long Duration Exposure Facility (LDEF) orbital mission. Previously-reported analyses of the timed impact data have established their spatio-temporal features, including the demonstration that a preponderance of the particles in this regime are orbital debris and that a large fraction of the debris particles are encountered as megameter-size clouds, some of which persist for long times. Short-term fluxes within such clouds can rise several orders of magnitude above the long-term average. These finding are consistent with the results of the first catastrophic hypervelocity laboratory impacts on a real satellite, recently reported in the press. Analysis continues on the geometric and evolutionary characteristics of these clouds, as well as on the isolation and characterization of the natural micrometeoroid component in the IDE data, but the unexpectedly large short-term variations in debris flux raises the question of how representative an indication of the multi-year average flux is given by the nearly one year of timed data. It has, therefore, always been one of the goals of IDE to conduct an optical survey of the craters on the IDE detectors, to obtain full-mission fluxes for comparisons with the timed data. This work is underway, and the results presently in hand are significant. Optical scanning of the ram and wake (East and West) panels is complete, and it is clear that the first year was in some respects not representative of the subsequent years. The 5.75-year average flux on East panel was 90 percent of the value predicted by the average flux recorded during the first year, while it was only 34 percent on West panel. This suggests that western hemisphere spacecraft launches are a major contributor to the long-term

Sparse data are available on long-term patient mortality following bariatric surgery as compared to the general population. The purpose of this study was to assess long-term mortality rates and identify risk factors for all-cause mortality following bariatric surgery. New York State (NYS) Planning and Research Cooperative System (SPARCS) longitudinal administrative data were used to identify 7,862 adult patients who underwent a primary laparoscopic bariatric surgery from 1999 to 2005. The Social Security Death Index database identified >30-day mortalities. Risk factors for mortality were screened using a univariate Cox proportional hazard (PH) model and analyzed using a multiple PH model. Based on age, gender, and race/ethnicity, actuarial projections for NYS mortality rates obtained from Centers of Disease Control were compared to the actual post-bariatric surgery mortality rates observed. The mean bariatric mortality rate was 2.5 % with 8-14 years of follow-up. Mean time to death ranged from 4 to 6 year and did not differ by operation (p = 0.073). From 1999 to 2010, the actuarial mortality rate predicted for the general NYS population was 2.1 % versus the observed 1.5 % for the bariatric surgery population (p = 0.005). Extrapolating to 2013, demonstrated the actuarial mortality predictions at 3.1 % versus the bariatric surgery patients' observed morality rate of 2.5 % (p = 0.01). Risk factors associated with an earlier time to death included: age, male gender, Medicare/Medicaid insurance, congestive heart failure, rheumatoid arthritis, pulmonary circulation disorders, and diabetes. No procedure-specific or perioperative complication impact for time-to-death was found. Long-term mortality rate of patients undergoing bariatric surgery significantly improves as compared to the general population regardless of bariatric operation performed. Additionally, perioperative complications do not increase long-term mortality risk. This study did identify specific patient

Introduction Scabies is a major public health problem in the Pacific and is associated with an increased risk of bacterial skin infections, glomerulonephritis and rheumatic fever. Mass drug administration with ivermectin is a promising strategy for the control of scabies. Mass treatment with ivermectin followed by active case finding was conducted in five communities in the Solomon Islands between 1997 and 2000 and resulted in a significant reduction in the prevalence of both scabies and bacterial skin infections. Methods We conducted a prospective follow-up study of the communities where the original scabies control programme had been undertaken. All residents underwent a standardised examination for the detection of scabies and impetigo. Results Three hundred and thirty eight residents were examined, representing 69% of the total population of the five communities. Only 1 case of scabies was found, in an adult who had recently returned from the mainland. The prevalence of active impetigo was 8.8% overall and 12.4% in children aged 12 years or less. Discussion We found an extremely low prevalence of scabies 15 years after the cessation of a scabies control programme. The prevalence of impetigo had also declined further since the end of the control programme. Our results suggest that a combination of mass treatment with ivermectin and intensive active case finding may result in long term control of scabies. Larger scale studies and integration with other neglected tropical disease control programmes should be priorities for scabies control efforts. PMID:26624616

Excessive accumulation of reactive oxygen species (ROS) and chronic activation of mechanistic target of rapamycin (mTOR) complex 1 (mTORC1) are well-characterized promoters of aging and age-associated degenerative pathologies. Sestrins, a family of highly conserved stress-inducible proteins, are important negative regulators of both ROS and mTORC1 signaling pathways; however, the mechanistic basis of how Sestrins suppress these pathways remains elusive. In the past couple of years, breakthrough discoveries about Sestrin signaling and its molecular nature have markedly increased our biochemical understanding of Sestrin function. These discoveries have also uncovered new potential therapeutic strategies that may eventually enable us to attenuate agingmore » and age-associated diseases.« less

Short-term load forecasting of power system

NASA Astrophysics Data System (ADS)

Xu, Xiaobin

2017-05-01

In order to ensure the scientific nature of optimization about power system, it is necessary to improve the load forecasting accuracy. Power system load forecasting is based on accurate statistical data and survey data, starting from the history and current situation of electricity consumption, with a scientific method to predict the future development trend of power load and change the law of science. Short-term load forecasting is the basis of power system operation and analysis, which is of great significance to unit combination, economic dispatch and safety check. Therefore, the load forecasting of the power system is explained in detail in this paper. First, we use the data from 2012 to 2014 to establish the partial least squares model to regression analysis the relationship between daily maximum load, daily minimum load, daily average load and each meteorological factor, and select the highest peak by observing the regression coefficient histogram Day maximum temperature, daily minimum temperature and daily average temperature as the meteorological factors to improve the accuracy of load forecasting indicators. Secondly, in the case of uncertain climate impact, we use the time series model to predict the load data for 2015, respectively, the 2009-2014 load data were sorted out, through the previous six years of the data to forecast the data for this time in 2015. The criterion for the accuracy of the prediction is the average of the standard deviations for the prediction results and average load for the previous six years. Finally, considering the climate effect, we use the BP neural network model to predict the data in 2015, and optimize the forecast results on the basis of the time series model.

Flood effects on an Alaskan stream restoration project: the value of long-term monitoring

USGS Publications Warehouse

Densmore, Roseann V.; Karle, Kenneth F.

2009-01-01

On a nationwide basis, few stream restoration projects have long-term programs in place to monitor the effects of floods on channel and floodplain configuration and floodplain vegetation, but long-term and event-based monitoring is required to measure the effects of these stochastic events and to use the knowledge for adaptive management and the design of future projects. This paper describes a long-term monitoring effort (15 years) on a stream restoration project in Glen Creek in Denali National Park and Preserve in Alaska. The stream channel and floodplain of Glen Creek had been severely degraded over a period of 80 years by placer mining for gold, which left many reaches with unstable and incised streambeds without functioning vegetated floodplains. The objectives of the original project, initiated in 1991, were to develop and test methods for the hydraulic design of channel and floodplain morphology and for floodplain stabilization and riparian habitat recovery, and to conduct research and monitoring to provide information for future projects in similar degraded watersheds. Monitoring methods included surveyed stream cross-sections, vegetation plots, and aerial, ground, and satellite photos. In this paper we address the immediate and outlying effects of a 25-year flood on the stream and floodplain geometry and riparian vegetation. The long-term monitoring revealed that significant channel widening occurred following the flood, likely caused by excessive upstream sediment loading and the fairly slow development of floodplain vegetation in this climate. Our results illustrated design flaws, particularly in regard to identification and analysis of sediment sources and the dominant processes of channel adjustment.

On the Use of a Mixed Gaussian/Finite-Element Basis Set for the Calculation of Rydberg States

Configuration-interaction studies are reported for the Rydberg states of the helium atom using mixed Gaussian/finite-element (GTO/FE) one particle basis sets. Standard Gaussian valence basis sets are employed, like those, used extensively in quantum chemistry calculations. It is shown that the term values for high-lying Rydberg states of the helium atom can be obtained accurately (within 1 cm -1), even for a small GTO set, by augmenting the n-particle space with configurations, where orthonormalized interpolation polynomials are singly occupied.

More than 10 years of outcomes for sleeve gastrectomy (LSG) have not yet been documented. Analysis of>11 years of outcomes of isolated LSG in terms of progression of weight, patient satisfaction, and evolution of co-morbidities and gastroesophageal reflux disease (GERD) treatment. Two European private hospitals. Chart review and personal interview in consecutive patients who underwent primary isolated LSG (2001-2003). Of the 110 consecutive patients, complete follow-up data was available in 65 (59.1%). Mean follow-up was 11.7±.4 years. Two patients had died of non-procedure-related causes. Twenty (31.7%) patients required 21 reoperations: 14 conversions (10 duodenal switch (DS), 4 Roux-en-Y gastric bypass (RYGB), and 3 resleeve procedures) for weight issues and 2 conversions (RYGB), and 2 hiatoplasties for gastroesophageal reflux disease (GERD). For the 47 (74.6%) individuals who thus kept the simple sleeve construction, percentage of excess body mass index loss (%EBMIL) at 11+years was 62.5%, versus 81.7% (P = .015) for the 16 patients who underwent conversion to another construction. Mean %EBMIL for the entire cohort was 67.4%. At 11+years postoperatively, 30 patients versus 28 preoperatively required treatment for co-morbidities. None of the 7 patients preoperatively suffering from GERD were cured by the LSG procedure. Nine additional patients developed de novo GERD. Overall satisfaction rate was 8 (interquartile range 2) on a scale of 0-10. Isolated LSG provides a long-term %EBMIL of 62.5%. Conversion to another construction, required in 25% of the cases, provides a %EBMIL of 81.7% (P = .015). Patient satisfaction score remains good despite unfavorable GERD outcomes.

This study tested the effect of a short-term coordination program focused on improving the agility of school children ages 7 to 8 years. Healthy Japanese children were placed in an experimental group of 26 children (10 girls, 16 boys) and a control group of 20 children (9 girls, 11 boys). The experimental group participated in 10 coordination program sessions during recesses; each session was performed 1 to 3 times per week, for 26 days. No differences were observed between the groups in repeated side-step scores prior to the program, although an interaction was observed after the completion of the treatment. The short-term coordination program was effective in increasing the agility of elementary school children aged 7 to 8 years.

2014-01-01

Background & Objectives : We report 17 years outcome of subsequent pregnancies of women with severe Mitral Stenosis (MS) who underwent Mitral Balloon Valvuloplasty (MBV) during pregnancy and the follow up of the children born of such pregnancies. Methods: Twenty three pregnant patients suffering from severe MS (NYHA-New York Heart Association class III/IV) who underwent MBV by Inoue balloon catheter technique during second trimester were enrolled. The study was performed between January 1992 and December 2008 at King Faisal Specialist Hospital & Research Centre, Riyadh, Saudi Arabia, during which time, details about the obstetric outcome and childhood development were recorded. Mean follow up period was 10± 5.5 years (range 1-17 years). Results: MBV was successful in all patients with improvement in their NYHA class to I/II. All patients were followed until term and had uneventful course after MBV. Twenty two (95.6%) patients delivered 23 babies including a twin birth. These children exhibited normal growth and development according to their age. Nineteen patients had further pregnancies and gave birth to 38 live & healthy babies with one still birth and no unfavorable maternal outcome. Of these, 97.4% were singleton pregnancies while 2.6% were twin pregnancies. Spontaneous abortions were recorded in 21.5% and there was one still birth (2.5%) and one ectopic pregnancy (2.5%). Conclusion : Mitral Balloon Valvuloplasty is a safe and useful procedure during pregnancy, with no short or long term adverse affects on the mothers and their obstetric future. The children born of subsequent pregnancies exhibited normal physical and mental development. PMID:24639837

To assess the long term complications of JJ stent, the management of complications and the role of endoscopic approach to manage these complications. Nineteen patients with indwelling JJ stent for a duration of more than 6 months were included in this study. Patients were assessed with X-ray KUB, USG KUB, blood urea, creatinine and DTPA renogram. Data were analyzed by Microsoft excel 2007. Out of 19 patients 12 (63.16%) were male and 7 (36.84%) were female. The mean age was 39.78 ± 13.69 years., Mean duration for which the stent was in situ was 29.56 months. The most common complication was broken stent, in 11 cases (57.89%). Other complications were migration in 5 (26.32%), encrustation in 2 (10.52%) and 1 case of (5.26%) stone formation. Eighteen cases were managed by endoscopic approaches. A total of 22 procedures were performed to treat the complications. Eleven cases were managed by a single procedure and 8 patients required multiple procedures. All were managed successfully with no death reported. Post-operative complications were seen in eight cases (42.11%). JJ stent related long-term complications are not uncommon and are usually seen after 6 months of indwelling time. Endourological procedure should be the initial approach with a high success rate. Coordinated use multimodality and technology helps in management of difficult cases. Open surgery is rarely required. Prevention of the complication by judicious use and early removal is the cornerstone.

the aim of this study was to document the choice between prosthesis and bioprosthesis in cases of valvular replacement during the seventh decade of life. a retrospective and cooperative study linking eleven cardiac surgical teams and five medical cardiology teams combined 497 subjects born between 1915 and 1925 (average age 64.4 years) who underwent aortic (313 cases) or mitral (184 cases) valvular replacement with mechanical prosthesis (259 cases) or bioprosthesis (238 cases). Information was collected at each centre during the year 2000 on the long term evolution (going back 15 years), in particular on the mortality, non-fatal complications linked to the valve, cardiac complications and extra-cardiac events. These results were subjected to statistical analysis. the operative mortality of this group was 4.8%. The 15 year survival was 46% for the aortic mechanical prostheses, 32% for the aortic bioprostheses (p=0.04). 34% for the mitral bioprostheses and 33% for the mitral mechanical prostheses. Events linked to the valve were more frequent for the mitral valvulopathies than for the aortic valves (49% vs 26%, p<0.001). The absence of events linked to the valve at 15 years was 69% for the aortic mechanical prostheses and 68% for the aortic bioprostheses. This was the case in only 57% of mitral mechanical prostheses and 36% of the mitral bioprostheses (p=0.11). Thromboembolic accidents were three times more frequent in the mitrals than in the aortics (11.5 vs 3.8%, p=0.002). Haemorrhage was four times more frequent for the mechanical prostheses than for the bioprostheses (7.7 vs 2%, p=0.01). The risk of degeneration for the aortic bioprostheses was 20% at 15 years, three times less so after 65 years of age (p=0.03). At 48% it was much higher in the mitral valves at 15 years with no significant difference before and after 65 years of age (p=0.3). the current life expectancy of subjects in their seventh decade is important.

Depressive disorders belong to the most frequent diseases worldwide showing a lifetime prevalence of up to 20%. Moreover they are one of the leading causes for the amount of years lived with disability. Increasing knowledge about the pathological mechanisms underlying depressive syndromes is obtained by using modern neurobiological research-techniques. Thereby some older theories that have been the basis of emotion-research for decades--like the monoamine hypothesis--have been strengthened. In addition new aspects of the pathological processes underlying depressive disturbances have been unraveled. In this review established models and recent findings will be discussed, to bridge various research-fields, ranging from genetics, epigenetics and morphological changes to the functional consequences of depression. Finally therapeutic implications that could be derived from these results will be presented, showing up putative possibilities for diagnosis and treatment of depressive syndromes.

Non-selective beta-blockers are the mainstay of medical therapy for portal hypertension in liver cirrhosis. Inhibitors of phosphodiesterase-5 (PDE-5-inhibitors) reduce portal pressure in the acute setting by > 10% which may suggest a long-term beneficial effect. Currently, there is no available data on long-term treatment of portal hypertension with PDE-5-inhibitors. This case of a patient with liver cirrhosis secondary to autoimmune liver disease with episodes of bleeding from esophageal varices is the first documented case in which a treatment with a PDE-5-inhibitor for eight years was monitored. In the acute setting, the PDE-5-inhibitor Vardenafil lowered portal pressure by 13%. The portal blood flow increased by 28% based on Doppler sonography and by 16% using MRI technique. As maintenance medication the PDE-5-inhibitor Tadalafil was used for eight consecutive years with comparable effects on portal pressure and portal blood flow. There were no recurrence of bleeding and no formation of new varices. Influencing the NO-pathway by the use of PDE-5 inhibitors may have long-term beneficial effects in compensated cirrhosis.

Chemical space networks (CSNs) have been introduced as a coordinate-free representation of chemical space. In CSNs, nodes represent compounds and edges pairwise similarity relationships. These network representations are mostly used to navigate sections of biologically relevant chemical space. Different types of CSNs have been designed on the basis of alternative similarity measures including continuous numerical similarity values or substructure-based similarity criteria. CSNs can be characterized and compared on the basis of statistical concepts from network science. Herein, a new CSN design is introduced that is based upon asymmetric similarity assessment using the Tversky coefficient and termed TV-CSN. Compared to other CSNs, TV-CSNs have unique features. While CSNs typically contain separate compound communities and exhibit small world character, many TV-CSNs are also scale-free in nature and contain hubs, i.e., extensively connected central compounds. Compared to other CSNs, these hubs are a characteristic of TV-CSN topology. Hub-containing compound communities are of particular interest for the exploration of structure-activity relationships.

Diabetes is a complex metabolic disease that exposes patients to the deleterious effects of hyperglycemia on various organs. Achievement of normoglycemia with exogenous insulin treatment requires the use of high doses of hormone, which increases the risk of life-threatening hypoglycemic episodes. We developed a gene therapy approach to control diabetic hyperglycemia based on co-expression of the insulin and glucokinase genes in skeletal muscle. Previous studies proved the feasibility of gene delivery to large diabetic animals with adeno-associated viral (AAV) vectors. Here, we report the long-term (∼8 years) follow-up after a single administration of therapeutic vectors to diabetic dogs. Successful, multi-year control of glycemia was achieved without the need of supplementation with exogenous insulin. Metabolic correction was demonstrated through normalization of serum levels of fructosamine, triglycerides, and cholesterol and remarkable improvement in the response to an oral glucose challenge. The persistence of vector genomes and therapeutic transgene expression years after vector delivery was documented in multiple samples from treated muscles, which showed normal morphology. Thus, this study demonstrates the long-term efficacy and safety of insulin and glucokinase gene transfer in large animals and especially the ability of the system to respond to the changes in metabolic needs as animals grow older.

Job strain has been implicated in a range of employee health outcomes including psychiatric health. Much of the literature is drawn from studies that utilise cross-sectional designs, whilst the long-term follow-up of participants is limited. We examine the short and long-term risks of job strain for depression and wellbeing over a 12-year period. In particular, we utilise measures of wellbeing to emphasise the importance of discriminating between indices of subjective and psychological wellbeing that complement measures of mental health. Participants (n = 2530) were aged between 40 and 44 years at baseline and were drawn from the Personality and Total Health (PATH) Through Life Project. Participants were observed once every 4 years for 12 years. A high strain job was associated with an increased risk of reporting sub-syndromal [RRR = 1.66 (95 % CI 1.23; 2.25), p < 0.001], minor [RRR = 1.92 (95 % CI 1.19; 3.10), p < 0.001] and major depression [RRR = 2.19 (95 % CI 1.30; 3.67), p < 0.001], but strain was not a long-term risk for depression 4 years later. In contrast, strain was a risk for both cross-sectional and longitudinal wellbeing outcomes. Moving into a high strain job was a risk for developing depression [RRR = 1.81 (95 % CI 1.26; 2.59), p < 0.001], but the cumulative exposure to a high strain job was not associated with poorer outcomes in adjusted models. Overall, our results emphasise the importance of current job strain, and the risk of moving into a high strain job, on adverse mental health and wellbeing outcomes. Effects were not consistent between indices of mental health, subjective or psychological wellbeing, supporting the need to dedifferentiate between wellbeing and mental health.

To date, there is a lack of long-term safety and efficacy data for iron chelation therapy in transfusion-dependent patients with sickle cell disease (SCD). To evaluate the long-term safety and efficacy of deferasirox (a once-daily oral iron chelator), patients with SCD completing a 1-year, Phase II, randomized, deferoxamine (DFO)-controlled study entered a 4-year extension, continuing to receive deferasirox, or switching from DFO to deferasirox. Average actual deferasirox dose was 19·4 ± 6·3 mg/kg per d. Of 185 patients who received at least one deferasirox dose, 33·5% completed the 5-year study. The most common reasons for discontinuation were withdrawal of consent (23·8%), lost to follow-up (9·2%) and adverse events (AEs) (7·6%). Investigator-assessed drug-related AEs were predominantly gastrointestinal [including nausea (14·6%), diarrhoea (10·8%)], mild-to-moderate and transient in nature. Creatinine clearance remained within the normal range throughout the study. Despite conservative initial dosing, serum ferritin levels in patients with ≥4 years deferasirox exposure significantly decreased by −591 μg/l (95% confidence intervals, −1411, −280 μg/l; P=0·027; n=67). Long-term deferasirox treatment for up to 5 years had a clinically acceptable safety profile, including maintenance of normal renal function, in patients with SCD. Iron burden was substantially reduced with appropriate dosing in patients treated for at least 4 years. PMID:21592110

The information supplied by this 30-year solid waste forecast has been compiled as a source document to the Waste Management Environmental Impact Statement (WMEIS). The WMEIS will help to select a sitewide strategic approach to managing present and future Savannah River Site (SRS) waste generated from ongoing operations, environmental restoration (ER) activities, transition from nuclear production to other missions, and decontamination and decommissioning (D&D) programs. The EIS will support project-level decisions on the operation of specific treatment, storage, and disposal facilities within the near term (10 years or less). In addition, the EIS will provide a baseline for analysis ofmore » future waste management activities and a basis for the evaluation of the specific waste management alternatives. This 30-year solid waste forecast will be used as the initial basis for the EIS decision-making process. The Site generates and manages many types and categories of waste. With a few exceptions, waste types are divided into two broad groups-high-level waste and solid waste. High-level waste consists primarily of liquid radioactive waste, which is addressed in a separate forecast and is not discussed further in this document. The waste types discussed in this solid waste forecast are sanitary waste, hazardous waste, low-level mixed waste, low-level radioactive waste, and transuranic waste. As activities at SRS change from primarily production to primarily decontamination and decommissioning and environmental restoration, the volume of each waste s being managed will change significantly. This report acknowledges the changes in Site Missions when developing the 30-year solid waste forecast.« less

Effective empirical corrections for basis set superposition error in the def2-SVPD basis: gCP and DFT-C

NASA Astrophysics Data System (ADS)

Witte, Jonathon; Neaton, Jeffrey B.; Head-Gordon, Martin

2017-06-01

With the aim of mitigating the basis set error in density functional theory (DFT) calculations employing local basis sets, we herein develop two empirical corrections for basis set superposition error (BSSE) in the def2-SVPD basis, a basis which—when stripped of BSSE—is capable of providing near-complete-basis DFT results for non-covalent interactions. Specifically, we adapt the existing pairwise geometrical counterpoise (gCP) approach to the def2-SVPD basis, and we develop a beyond-pairwise approach, DFT-C, which we parameterize across a small set of intermolecular interactions. Both gCP and DFT-C are evaluated against the traditional Boys-Bernardi counterpoise correction across a set of 3402 non-covalent binding energies and isomerization energies. We find that the DFT-C method represents a significant improvement over gCP, particularly for non-covalently-interacting molecular clusters. Moreover, DFT-C is transferable among density functionals and can be combined with existing functionals—such as B97M-V—to recover large-basis results at a fraction of the cost.

Diabetes mellitus is the most common comorbidity in cystic fibrosis (CF). Recently, more attention has been paid to early glucose metabolism derangements (GMDs). The subject of this report is a female patient, affected by CF since 3 months of age. She presented with intermittent diabetes during early childhood. At the age of 10 years, oral glucose tolerance test (OGTT) was performed and showed glucose intolerance (IGT) status; glargine insulin therapy was started. At the age of 13 years, CF-related diabetes with fasting hyperglycemia occurred, so rapid insulin at meals was added. During the following year, clinical and nutritional status improved. Stable clinical conditions were observed in the following 3 years. This is the first case of very long-term follow-up concerning a CF patient with GMDs. Our case confirms the importance of paying attention to early GMDs in very young CF patients and seems to suggest that earlier therapy could ameliorate CF natural history.

This study explored whether extremely preterm (EPT) children had different sleep characteristics in childhood than children born at term and how neurodevelopmental disabilities (NDD) affected sleep in children born EPT. A Norwegian national cohort of 231 children born EPT from 1999 to 2000 and separate study data on 556 children born at term in 2001 were compared. Parental questionnaires mapped the children's current sleep habits at 11 years of age, namely the prevalence of sleep problems throughout childhood until this age and five categories of sleep problems. In addition, the EPT children were clinically assessed at five years of age. The EPT children had different sleep habits than the controls, for example they went to bed earlier. EPT children had a higher prevalence of sleep problems than the controls throughout childhood (26% versus 14%, p < 0.001) and this was also higher for the 93 EPT children with no NDD (20%) than for the controls (14%) and increased with increasing NDD to 67% (p = 0.015) for the six children with severe NDD. EPT children had different sleep habits to term-born controls at 11 years of age, including those with no NDD. The prevalence of sleep problems increased with increasing NDD. ©2017 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

The Complex Genetic Basis of Congenital Heart Defects

2017-01-01

Twenty years ago, chromosomal abnormalities were the only identifiable genetic causes of a small fraction of congenital heart defects (CHD). Today, a de novo or inherited genetic abnormality can be identified as pathogenic in one-third of cases. We refer to them here as monogenic causes, insofar as the genetic abnormality has a readily detectable, large effect. What explains the other two-thirds? This review considers a complex genetic basis. That is, a combination of genetic mutations or variants that individually may have little or no detectable effect contribute to the pathogenesis of a heart defect. Genes in the embryo that act directly in cardiac developmental pathways have received the most attention, but genes in the mother that establish the gestational milieu via pathways related to metabolism and aging also have an effect. A growing body of evidence highlights the pathogenic significance of genetic interactions in the embryo and maternal effects that have a genetic basis. The investigation of CHD as guided by a complex genetic model could help estimate risk more precisely and logically lead to a means of prevention. PMID:28381817

To evaluate the safety of saxagliptin ± metformin over 4 years in patients with Type 2 diabetes mellitus. Drug-naive (n = 401; study 11) or metformin-treated (n = 743; study 14) adults with HbA(1c) of 53-86 mmol/mol (7.0-10%) were enrolled in two randomized, placebo-controlled, double-blind trials of saxagliptin 2.5, 5 or 10 mg/day. Patients rescued during or completing 24 weeks of treatment could continue in a 42-month long-term blinded phase, for which the primary goal was assessment of safety and tolerability. Between-group efficacy was not evaluated in the long-term phase of study 11. Time to rescue or discontinuation because of inadequate glycaemic control, change from baseline in HbA(1c) and percentages of patients achieving HbA(1c) < 53 mmol/mol (< 7.0%) were assessed in study 14. No new safety findings were noted during the long-term phase. Most adverse events were mild or moderate, with slightly greater frequency of upper respiratory infections with saxagliptin. Hypoglycaemic event rates were similar with saxagliptin and placebo. In study 14, time to rescue or discontinuation because of inadequate glycaemic control was longer with saxagliptin plus metformin than for placebo plus metformin. From baseline to week 154, HbA(1c) decreased with saxagliptin but increased with placebo. Saxagliptin monotherapy or add-on to metformin is generally safe and well tolerated, with no increased risk of hypoglycaemia, for up to 4 years. © 2013 The Authors.

To examine the associations between Prechtl's General Movements Assessment (GMA), conducted from birth to term-equivalent age, and neurodevelopmental outcomes at 12 months corrected age, in infants born very preterm. One hundred and thirty-seven infants born before 30 weeks' gestation had serial GMA (categorized as 'normal' or 'abnormal') before term and at term-equivalent age. At 12 months corrected age, neurodevelopment was assessed using the Alberta Infant Motor Scale (AIMS); Neurological, Sensory, Motor, Developmental Assessment (NSMDA); and Touwen Infant Neurological Examination (TINE). The relationships between GMA at four time points and 12-month neurodevelopmental assessments were examined using regression models. Abnormal GMA at all time points were associated with worse continuous scores on the AIMS, NSMDA, and TINE (p<0.05). Abnormal GMA before term and at term-equivalent age were associated with increased odds of mild-severe dysfunction on the NSMDA (odds ratio [OR] 4.26, 95% confidence interval [CI] 1.55-11.71, p<0.01; and OR 4.16, 95% CI 1.55-11.17, p<0.01 respectively) and abnormal GMA before term with increased odds of suboptimal-abnormal motor function on the TINE (OR 2.75, 95% CI 1.10-6.85, p=0.03). Abnormal GMA before term and at term-equivalent age were associated with worse neurodevelopment at 12 months corrected age in children born very preterm. Abnormal general movements before term predict developmental deficits at 1 year in infants born very preterm. General Movements Assessment before term identifies at-risk infants born very preterm. © 2017 Mac Keith Press.

2014-01-01

Background/Objectives Short-term studies have suggested beneficial effects of a Palaeolithic-type diet (PD) on body weight and metabolic balance. We now report long-term effects in obese postmenopausal women of a PD on anthropometric measurements and metabolic balance, in comparison with a diet according to the Nordic Nutrition Recommendations (NNR). Subjects/Methods Seventy obese postmenopausal women (mean age 60 years, body mass index 33 kg/m2) were assigned to an ad libitum PD or NNR diet in a 2-year randomized controlled trial. The primary outcome was change in fat mass as measured by dual energy X-ray absorptiometry. Results Both groups significantly decreased total fat mass at 6 months (−6.5 and −2.6 kg) and 24 months (−4.6 and −2.9 kg), with a more pronounced fat loss in the PD group at 6 months (P<0.001), but not at 24 months (P=0.095). Waist circumference and sagittal diameter also decreased in both groups, with a more pronounced decrease in the PD group at 6 months (−11.1 vs. −5.8 cm, P=0.001 and −3.7 vs. −2.0 cm, P<0.001, respectively). Triglyceride levels decreased significantly more at 6 and 24 months in the PD group versus the NNR group (P<0.001 and P=0.004). Nitrogen excretion did not differ between groups. Conclusions A PD has greater beneficial effects versus an NNR diet regarding fat mass, abdominal obesity and triglyceride levels in obese postmenopausal women; effects not fully sustained for anthropometric measurements at 24 months. Adherence to protein intake was poor in the PD group. The long-term consequences of these changes remain to be studied. PMID:24473459

Disease modifying therapies (DMTs) reduce the frequency of relapses and accumulation of disability in multiple sclerosis (MS). Long-term persistence with treatment is important to optimize treatment benefit. This long-term, cohort study was conducted at the Calgary MS Clinic. All consenting adults with relapsing-remitting MS who started either glatiramer acetate (GA) or interferon-β 1a/1b (IFN-β) between January 1st, 1996 and July 1st, 2011 were included. Follow-up continued to February 1st, 2014. Time-to-discontinuation of the initial and subsequently-prescribed DMTs (switches) was analysed using Kaplan-Meier survival analyses. Group differences were compared using log-rank tests and multivariable Cox regression models. Analysis included 1471 participants; 906 were initially prescribed GA and 565 were initially prescribed IFN-β. Follow-up information was available for 87%; 29 (2%) were lost to follow-up and 160 (11%) moved from Southern Alberta while still using DMT. Median time-to-discontinuation of all injectable DMTs was 11.1 years. Participants with greater disability at treatment initiation, those who started treatment before age 30, and those who started between 2006 and 2011 were more likely to discontinue use of all injectable DMTs. Median time-to-discontinuation of the initial DMT was 8.6 years. Those initially prescribed GA remained on treatment longer. Of 610 participants who discontinued injectable DMT, 331 (54%) started an oral DMT, or a second-line DMT, or resumed injectable DMT after 90 days. Persistence with injectable DMTs was high in this long-term population-based study. Most participants who discontinued injectable DMT did not remain untreated. Further research is required to understand treatment outcomes and outcomes after stopping DMT. PMID:25867095

The lung allocation score restructured the distribution of scarce donor lungs for transplantation. The algorithm ranks waiting list patients according to medical urgency and expected benefit after transplantation. The purpose of this study was to evaluate the impact of the lung allocation score on short-term outcomes after lung transplantation. A multicenter retrospective cohort study was performed with data from 5 academic medical centers. Results of patients undergoing transplantation on the basis of the lung allocation score (May 4, 2005 to May 3, 2006) were compared with those of patients receiving transplants the preceding year before the lung allocation score was implemented (May 4, 2004, to May 3, 2005). The study reports on 341 patients (170 before the lung allocation score and 171 after). Waiting time decreased from 680.9 +/- 528.3 days to 445.6 +/- 516.9 days (P < .001). Recipient diagnoses changed with an increase in idiopathic pulmonary fibrosis and a decrease in emphysema and cystic fibrosis (P = .002). Postoperatively, primary graft dysfunction increased from 14.1% (24/170) to 22.9% (39/171) (P = .04) and intensive care unit length of stay increased from 5.7 +/- 6.7 days to 7.8 +/- 9.6 days (P = .04). Hospital mortality and 1-year survival were the same between groups (5.3% vs 5.3% and 90% vs 89%, respectively; P > .6) This multicenter retrospective review of short-term outcomes supports the fact that the lung allocation score is achieving its objectives. The lung allocation score reduced waiting time and altered the distribution of lung diseases for which transplantation was done on the basis of medical necessity. After transplantation, recipients have significantly higher rates of primary graft dysfunction and intensive care unit lengths of stay. However, hospital mortality and 1-year survival have not been adversely affected.

The functional basis of adaptive evolution in chemostats.

PubMed

Gresham, David; Hong, Jungeui

2015-01-01

Two of the central problems in biology are determining the molecular basis of adaptive evolution and understanding how cells regulate their growth. The chemostat is a device for culturing cells that provides great utility in tackling both of these problems: it enables precise control of the selective pressure under which organisms evolve and it facilitates experimental control of cell growth rate. The aim of this review is to synthesize results from studies of the functional basis of adaptive evolution in long-term chemostat selections using Escherichia coli and Saccharomyces cerevisiae. We describe the principle of the chemostat, provide a summary of studies of experimental evolution in chemostats, and use these studies to assess our current understanding of selection in the chemostat. Functional studies of adaptive evolution in chemostats provide a unique means of interrogating the genetic networks that control cell growth, which complements functional genomic approaches and quantitative trait loci (QTL) mapping in natural populations. An integrated approach to the study of adaptive evolution that accounts for both molecular function and evolutionary processes is critical to advancing our understanding of evolution. By renewing efforts to integrate these two research programs, experimental evolution in chemostats is ideally suited to extending the functional synthesis to the study of genetic networks. © FEMS 2015.

Whole-coal versus ash basis in coal geochemistry: a mathematical approach to consistent interpretations

USGS Publications Warehouse

Geboy, Nicholas J.; Engle, Mark A.; Hower, James C.

2013-01-01

Several standard methods require coal to be ashed prior to geochemical analysis. Researchers, however, are commonly interested in the compositional nature of the whole-coal, not its ash. Coal geochemical data for any given sample can, therefore, be reported in the ash basis on which it is analyzed or the whole-coal basis to which the ash basis data are back calculated. Basic univariate (mean, variance, distribution, etc.) and bivariate (correlation coefficients, etc.) measures of the same suite of samples can be very different depending which reporting basis the researcher uses. These differences are not real, but an artifact resulting from the compositional nature of most geochemical data. The technical term for this artifact is subcompositional incoherence. Since compositional data are forced to a constant sum, such as 100% or 1,000,000 ppm, they possess curvilinear properties which make the Euclidean principles on which most statistical tests rely inappropriate, leading to erroneous results. Applying the isometric logratio (ilr) transformation to compositional data allows them to be represented in Euclidean space and evaluated using traditional tests without fear of producing mathematically inconsistent results. When applied to coal geochemical data, the issues related to differences between the two reporting bases are resolved as demonstrated in this paper using major oxide and trace metal data from the Pennsylvanian-age Pond Creek coal of eastern Kentucky, USA. Following ilr transformation, univariate statistics, such as mean and variance, still differ between the ash basis and whole-coal basis, but in predictable and calculated manners. Further, the stability between two different components, a bivariate measure, is identical, regardless of the reporting basis. The application of ilr transformations addresses both the erroneous results of Euclidean-based measurements on compositional data as well as the inconsistencies observed on coal geochemical data

2015-01-01

Objectives: To assess the long term complications of JJ stent, the management of complications and the role of endoscopic approach to manage these complications. Materials and Methods: Nineteen patients with indwelling JJ stent for a duration of more than 6 months were included in this study. Patients were assessed with X-ray KUB, USG KUB, blood urea, creatinine and DTPA renogram. Data were analyzed by Microsoft excel 2007. Results: Out of 19 patients 12 (63.16%) were male and 7 (36.84%) were female. The mean age was 39.78 ± 13.69 years., Mean duration for which the stent was in situ was 29.56 months. The most common complication was broken stent, in 11 cases (57.89%). Other complications were migration in 5 (26.32%), encrustation in 2 (10.52%) and 1 case of (5.26%) stone formation. Eighteen cases were managed by endoscopic approaches. A total of 22 procedures were performed to treat the complications. Eleven cases were managed by a single procedure and 8 patients required multiple procedures. All were managed successfully with no death reported. Post-operative complications were seen in eight cases (42.11%). Conclusions: JJ stent related long-term complications are not uncommon and are usually seen after 6 months of indwelling time. Endourological procedure should be the initial approach with a high success rate. Coordinated use multimodality and technology helps in management of difficult cases. Open surgery is rarely required. Prevention of the complication by judicious use and early removal is the cornerstone. PMID:25657542

The Edwards Duromedics valve (Baxter Healthcare Corp., Edwards Division, Santa Ana, Calif.) was designed with a self-irrigating hinge mechanism to reduce thromboembolic complications. After good initial clinical results, distribution was suspended in 1988 after reports of valve fracture after 20,000 valves had been implanted. The manufacturer conducted extensive studies to improve the Edwards Duromedics and reintroduced a modified version, which is available as Edwards Tekna. The purpose of the study was the evaluation of long-term results of the original Edwards Duromedics that might be important for the current version, the Edwards Tekna valve. A prospective clinical 10-year follow-up was performed of 508 patients who underwent valve replacement with the Edwards Duromedics valve in the aortic (n = 268), mitral (n = 183), and aortic and mitral (n = 56) position. The perioperative mortality rate was 6.9%; follow-up was 98% complete, comprising 3648 patient-years for a mean follow-up of 86 months (range: 33 to 144 months). The actuarial freedom from complications at the 10-year follow-up and the incidence rate (percent per patient-year) were as follows: late mortality rate, 69.2% +/- 2.4% (3.5% per patient-year); thromboembolism, 90.7% +/- 1.6% (0.96% per patient-year); anticoagulation-related hemorrhage, 87.7% +/- 1.7% (1.34% per patient-year); prosthetic valve endocarditis, 96.7% +/- 0.09% (0.38% per patient-year); valve-related mortality rate, 89.3% +/- 1.6% (1.21% per patient-year); valve failure, 86.2% +/- 1.85% (1.54% per patient-year); and valve-related morbidity and mortality rate, 71.1% +/- 2.3% (3.2% per patient-year). Three leaflet escapes were observed (one lethal, two successful reoperations; 99.1% +/- 0.05% freedom, 0.08% per patient-year). All patients functionally improved (86% in New York Heart Association classes I and II), and incidence of anemia was insignificant. These results confirm that the Edwards Duromedics valve shows excellent performance

This study examined profiles of non-residential father engagement (i.e., support to the adolescent, contact frequency, remarriage, relocation, and interparental conflict) with their adolescent children (N = 156) six to eight years following divorce and the prospective relation between these profiles and the psychosocial functioning of their offspring, nine years later. Parental divorce occurred during late childhood to early adolescence; indicators of non-residential father engagement were assessed during adolescence, and mental health problems and academic achievement of offspring were assessed nine years later in young adulthood. Three profiles of father engagement were identified in our sample of mainly White, non-Hispanic divorced fathers: Moderate Involvement/Low Conflict, Low Involvement/Moderate Conflict, and High Involvement/High Conflict. Profiles differentially predicted offspring outcomes nine years later when they were young adults, controlling for quality of the mother-adolescent relationship, mother’s remarriage, mother’s income, and gender, age and offspring mental health problems in adolescence. Offspring of fathers characterized as Moderate Involvement/Low Conflict had the highest academic achievement and the lowest number of externalizing problems nine years later compared to offspring whose fathers had profiles indicating either the highest or lowest levels of involvement but higher levels of conflict. Results indicate that greater paternal psychosocial support and more frequent father-adolescent contact do not outweigh the negative impact of interparental conflict on youth outcomes in the long-term. Implications of findings for policy and intervention are discussed. PMID:24484456

Retrospective review. To assess the long-term outcomes of anterior spinal fusion (ASF) for treating thoracic adolescent idiopathic scoliosis (AIS). Although ASF is reported to provide good coronal and sagittal correction of the main thoracic (MT) AIS curves, the long-term outcomes of ASF is unknown. A consecutive series of 25 patients with Lenke 1 MT AIS were included. Outcome measures comprised radiographical measurements, pulmonary function, and Scoliosis Research Society outcome instrument (SRS-30) scores (preoperative SRS-30 scores were not documented). Postoperative surgical revisions and complications were recorded. Twenty-five patients were followed-up for 12 to 18 years (average, 15.2 yr). The average MT Cobb angle correction rate and the correction loss at the final follow-up were 56.7% and 9.2°, respectively. The average preoperative instrumented level of kyphosis was 8.3°, which significantly improved to 18.6° (P = 0.0003) at the final follow-up. The average percent-predicted forced vital capacity and forced expiratory volume in 1 second were significantly decreased during long-term follow-up measurements (73% and 69%; P = 0.0004 and 0.0016, respectively). However, no patient had complaints related to pulmonary function. The average total SRS-30 score was 4.0. Implant breakage was not observed. All patients, except 1 who required revision surgery, demonstrated solid fusion. Late instrumentation-related bronchial problems were observed in 1 patient who required implant removal and bronchial tube repair, 13 years after the initial surgery. Overall radiographical findings and patient outcome measures of ASF for Lenke 1 MT AIS were satisfactory at an average follow-up of 15 years. ASF provides significant sagittal correction of the main thoracic curve with long-term maintenance of sagittal profiles. Percent-predicted values of forced vital capacity and forced expiratory volume in 1 second were decreased in this cohort; however, no patient had complaints

Glacier foreland colonisation: distinguishing between short-term and long-term effects of climate change.

PubMed

Kaufmann, Rüdiger

2002-02-01

By comparing short-term (6 years) observations with long-term (>100 years) community changes reconstructed from the chronosequence along a glacier foreland, I show that the colonisation of recently deglaciated terrain by invertebrates may constitute a process reacting sensitively to temperature fluctuations. Early colonising stages (<30 years old) currently develop faster, and intermediate successional stages (30-50 years old) slower, than would be indicated by the long-term chronosequence pattern. These differences between the chronosequence approach and direct observation can be explained by a simple model relating the rate of community evolution to the temperature record. It would mean that an increase of 0.6°C in summer temperatures approximately doubled the speed of initial colonisation, whereas later successional stages were less sensitive to climate change. The present situation appears to result from unusually warm summers around 1950 and a warm period accelerating glacier retreat since 1980. In contrast to the long-term trend, all except the youngest communities have suffered a loss in diversity in recent years.

To predict the long-term survival results of clinical trials earlier than using actuarial methods and to assess the factors predictive of long-term cure in patients with limited-stage small-cell lung cancer. Between 1981 and 1998, 1417 new cases of small-cell lung cancer were diagnosed in Saskatchewan, Canada, of which 244 were limited stage and treated with curative intent. They were followed to the end of February 2002. A parametric lognormal statistical model was retrospectively validated to determine whether long-term survival rates could be estimated several years earlier than is possible using the standard life-table actuarial method. The survival time of the uncured group followed a lognormal distribution. Four 2-year periods of diagnosis were combined, and patients were followed as a cohort for an additional 2 years. The estimated 10-year cause-specific survival rate was 13% by the lognormal model. The Kaplan-Meier calculation for 10-year cause-specific survival rate was 15% +/- 3%. The data also showed that the absence of mediastinal lymphadenopathy and higher chest radiotherapy dose were significant prognostic factors on multivariate analysis (p < 0.05). Among the 163 patients given prophylactic cranial irradiation, a higher biologically effective dose to the brain did not improve survival or decrease the incidence of brain metastases. The lognormal model has been validated for the estimation of survival in patients with limited-stage small-cell lung cancer. A higher biologically effective dose to the brain did not improve survival or decrease the incidence of brain metastases.

Basis set construction for molecular electronic structure theory: natural orbital and Gauss-Slater basis for smooth pseudopotentials.

PubMed

Petruzielo, F R; Toulouse, Julien; Umrigar, C J

2011-02-14

A simple yet general method for constructing basis sets for molecular electronic structure calculations is presented. These basis sets consist of atomic natural orbitals from a multiconfigurational self-consistent field calculation supplemented with primitive functions, chosen such that the asymptotics are appropriate for the potential of the system. Primitives are optimized for the homonuclear diatomic molecule to produce a balanced basis set. Two general features that facilitate this basis construction are demonstrated. First, weak coupling exists between the optimal exponents of primitives with different angular momenta. Second, the optimal primitive exponents for a chosen system depend weakly on the particular level of theory employed for optimization. The explicit case considered here is a basis set appropriate for the Burkatzki-Filippi-Dolg pseudopotentials. Since these pseudopotentials are finite at nuclei and have a Coulomb tail, the recently proposed Gauss-Slater functions are the appropriate primitives. Double- and triple-zeta bases are developed for elements hydrogen through argon. These new bases offer significant gains over the corresponding Burkatzki-Filippi-Dolg bases at various levels of theory. Using a Gaussian expansion of the basis functions, these bases can be employed in any electronic structure method. Quantum Monte Carlo provides an added benefit: expansions are unnecessary since the integrals are evaluated numerically.

Short-term outcome studies of antipsychotic dose-reduction/discontinuation strategies in patients with remitted first-episode psychosis (FEP) showed higher relapse rates but no other disadvantages compared with maintenance treatment; however, long-term effects on recovery have not been studied before. To compare rates of recovery in patients with remitted FEP after 7 years of follow-up of a dose reduction/discontinuation (DR) vs maintenance treatment (MT) trial. Seven-year follow-up of a 2-year open randomized clinical trial comparing MT and DR. One hundred twenty-eight patients participating in the original trial were recruited from 257 patients with FEP referred from October 2001 to December 2002 to 7 mental health care services in a 3.2 million-population catchment area. Of these, 111 patients refused to participate and 18 patients did not experience remission. PARTICIPANTS After 7 years, 103 patients (80.5%) of 128 patients who were included in the original trial were located and consented to follow-up assessment. After 6 months of remission, patients were randomly assigned to DR strategy or MT for 18 months. After the trial, treatment was at the discretion of the clinician. Primary outcome was rate of recovery, defined as meeting the criteria of symptomatic and functional remission. Determinants of recovery were examined using logistic regression analysis; the treatment strategy (MT or DR) was controlled for baseline parameters. The DR patients experienced twice the recovery rate of the MT patients (40.4% vs 17.6%). Logistic regression showed an odds ratio of 3.49 (P = .01). Better DR recovery rates were related to higher functional remission rates in the DR group but were not related to symptomatic remission rates. Dose reduction/discontinuation of antipsychotics during the early stages of remitted FEP shows superior long-term recovery rates compared with the rates achieved with MT. To our knowledge, this is the first study showing long-term gains of an early

Accurate analysis of meteorological and pyranometric data for long-term analysis is the basis of decision-making for banks and investors, regarding solar energy conversion systems. This has led to the development of methodologies for the generation of Typical Meteorological Years (TMY) datasets. The most used method for solar energy conversion systems was proposed in 1978 by the Sandia Laboratory (Hall et al., 1978) considering a specific weighted combination of different meteorological variables with notably global, diffuse horizontal and direct normal irradiances, air temperature, wind speed, relative humidity. In 2012, a new approach was proposed in the framework of the European project FP7 ENDORSE. It introduced the concept of "driver" that is defined by the user as an explicit function of the pyranometric and meteorological relevant variables to improve the representativeness of the TMY datasets with respect the specific solar energy conversion system of interest. The present study aims at comparing and benchmarking different TMY datasets considering a specific Concentrated-PV (CPV) system as the solar energy conversion system of interest. Using long-term (15+ years) time-series of high quality meteorological and pyranometric ground measurements, three types of TMY datasets generated by the following methods: the Sandia method, a simplified driver with DNI as the only representative variable and a more sophisticated driver. The latter takes into account the sensitivities of the CPV system with respect to the spectral distribution of the solar irradiance and wind speed. Different TMY datasets from the three methods have been generated considering different numbers of years in the historical dataset, ranging from 5 to 15 years. The comparisons and benchmarking of these TMY datasets are conducted considering the long-term time series of simulated CPV electric production as a reference. The results of this benchmarking clearly show that the Sandia method is not

Taxane-induced neuropathy is a frequent complication, in particular in women with breast cancer. The incidence can be variable and ranges from 11 to 87%, depending on the taxane used and identified risk factors, such as cumulative dose, additional neurotoxic chemotherapy agents and previous nerve fragility. However, little is known about long-term outcome and interference with daily life activities. The objective of this study was to assess clinical and electrophysiological neurological evaluation (ENMG) in a cohort of patients, 1-13 years (median 3 years) after the end of the last cure. Sixty-nine women were enrolled in the lymphology unit of Cognacq-Jay's Hospital. They were 58 ± 9 years old (mean age ± SD) and had been treated by docetexel (n = 56), paclitaxel (n = 10) or both (n = 3), 1-13 years before. Sensory neuropathy occurred in 64% and totally disappeared within months for only 14% after cessation of treatment. However, if symptoms were still present at the time of examination, they were considered as minor by almost all patients, with no interference with daily life activities (grade 2 CTCAE v.3.0). ENMG was accepted by 14 patients; it was normal in 7, and showed sensory axonal neuropathy in 5 and sensory-motor neuropathy in 2. The incidence of taxane-induced neuropathy is high, more frequent with paclitaxel than docetaxel, and is characterized by minor or moderate axonal sensory polyneuropathy. When persistent, it is extremely well tolerated by the patient. When clinical motor signs occur, the patient should be referred to a neurologist.

AIM To examine the long-term effects induced by treatment with the function regulator (FR-2) appliance 7 years post-treatment compared with untreated class II subjects. SUBJECTS AND METHODS The FR-2 sample was collected prospectively and comprised 17 subjects (10 boys and 7 girls, mean age 10.8 years) who were treated with the FR-2 appliance for 1.7 years and re-evaluated 7.1 years after treatment. The step-by-step mandibular advancement was performed gradually (increments up to 3–4 mm), until a ‘super class I’ molar relationship was obtained. The control group consisted of 17 class II subjects (9 boys and 8 girls, mean age 11.3 years) with class II malocclusion, excessive overjet, and class II molar relationship, matched to the treated group as to ages at all times, gender distribution, and stages of skeletal maturity (evaluated by the cervical vertebral maturation method). The lateral cephalograms were analysed at T1 (initial), T2 (final), and T3 (7.1 years post-treatment). The compatibility between the groups and the comparisons of their changes at T1–T2, T2–T3, and T1–T3 intervals were examined by independent sample t-tests (P < 0.05). RESULTS FR-2 treatment provided a significant improvement in the maxillomandibular relationship due to an increase in mandibular length compared with controls, which remained stable over time. Also overjet, overbite, and molar relationship corrections demonstrated stability. Among dentoalveolar changes, only the increased mesial movement of the mandibular molars in the FR-2 group demonstrated stability. CONCLUSIONS Correction of class II malocclusion remained stable 7 years after FR-2 treatment mainly due to the stability of the skeletal changes. PMID:23736378

We studied the effect of long-term alglucerase/imiglucerase (Ceredase®/Cerezyme®, Genzyme, a Sanofi company, Cambridge, MA, USA) treatment on hematological, visceral, and bone manifestations of Gaucher disease type 1 (GD1). The International Collaborative Gaucher Group (ICGG) Gaucher Registry identified GD1 patients treated with alglucerase/imiglucerase who had dose and clinical data at first infusion and after 10 years of follow-up. Data for hemoglobin, platelet count, organ volumes, bone pain, and bone crisis were analyzed. Tests of the null hypothesis (no change from first infusion to 10 years) were performed using t tests for within-patient absolute change in continuous measurements and McNemar/chi-square tests for change in distributions using categorical values. An alpha level of 0.05 designated statistical significance. As of October 2011, 557 nonsplenectomized and 200 splenectomized patients met the inclusion criteria. The majority of GD1 patients had at least one N370S allele. Compared with nonsplenectomized patients at first infusion, splenectomized patients had lower percentages of anemia (26.0 % vs. 42.8 %) and thrombocytopenia (14.2 % vs. 76.3 %), similar percentages of moderate or severe hepatomegaly (81.2 % vs. 80.0 %), and higher percentages of bone pain (88.9 % vs. 52.4 %) and bone crises (38.3 % vs. 16.0 %). After 10 years, both groups showed significant (p < 0.05) improvements in mean hemoglobin levels, platelet count, liver, and spleen (nonsplenectomized) volumes, and bone crises. Initial dosing in both groups ranged from <15 U/kg to ≤90 U/kg every 2 weeks. After 10 years, the majority was receiving 15 to ≤45 U/kg every 2 weeks. Ten years of imiglucerase treatment results in sustainable improvements in all GD1 parameters.

Neural basis of bilingual language control.

Calabria, Marco; Costa, Albert; Green, David W; Abutalebi, Jubin

Acquiring and speaking a second language increases demand on the processes of language control for bilingual as compared to monolingual speakers. Language control for bilingual speakers involves the ability to keep the two languages separated to avoid interference and to select one language or the other in a given conversational context. This ability is what we refer with the term "bilingual language control" (BLC). It is now well established that the architecture of this complex system of language control encompasses brain networks involving cortical and subcortical structures, each responsible for different cognitive processes such as goal maintenance, conflict monitoring, interference suppression, and selective response inhibition. Furthermore, advances have been made in determining the overlap between the BLC and the nonlinguistic executive control networks, under the hypothesis that the BLC processes are just an instantiation of a more domain-general control system. Here, we review the current knowledge about the neural basis of these control systems. Results from brain imaging studies of healthy adults and on the performance of bilingual individuals with brain damage are discussed. © 2018 New York Academy of Sciences.

Comparison of localized basis and plane-wave basis for density-functional calculations of organic molecules on metals

Localized pseudoatomic orbitals (PAOs) are mainly optimized and tested for the strong chemical bonds within molecules and solids with their proven accuracy and efficiency, but are prone to significant basis set superposition error (BSSE) for weakly interacting systems. Here we test the accuracy of PAO basis in comparison with the BSSE-free plane-wave basis for the physisorption of pentacene molecule on Au (001) by calculating the binding energy, adsorption height, and energy level alignment. We show that both the large cutoff radius for localized PAOs and the counter-poise correction for BSSE are necessary to obtain well-converged physical properties. Thereby obtained results are as accurate as the plane-wave basis results. The comparison with experiment is given as well.

To examine the accommodative amplitude and convergence in 10-year-old prematurely born children previously screened for retinopathy of prematurity (ROP) and to compare with full-term controls of the same age. Two-hundred and thirteen prematurely born and 217 children born at term were included. Accommodative amplitude and near-point convergence were assessed, together with best-corrected visual acuity (VA). A questionnaire was answered regarding possible problems at school. Binocular accommodation (P = 0.03) and convergence (P = 0.003) were significantly poorer in prematurely born children. Accommodation was correlated to neurological findings in the preterm group, but not to the degree of prematurity or stage of ROP. Regarding convergence there were no correlations to neurology, stage of ROP, or degree of prematurity. For neither accommodation nor convergence were any correlations with distance and near VA found. Preterm children had a higher prevalence of school problems, and there was an association with poor accommodation. Prematurely born children had poorer accommodation and convergence than full-term children, but no association with near VA was found. The reduction of accommodative amplitude and convergence was small and was probably of little clinical significance. However, it may have additional effects on other ophthalmological problems and school problems in the preterm group.

This review surveys the literature on the search for the genetic basis of hypertension during the 10 months since November 2003. The goals set forth by this search are defined and the highlights of the work accomplished are provided. The search for the genetic basis of hypertension is ongoing, generating an abundance of new data. These data consist of a large number of candidate genes, association of previously known and novel candidate genes with various facets of hypertension, detection of new quantitative trait loci and identification of genes that mediate susceptibility to hypertension. The renin-zangiotensin-aldosterone system continues to dominate the interest of investigators. Other gene systems are also emerging but a single-gene system cannot be singled out beyond the renin-angiotensin-aldosterone system and the data are mostly sporadic and do not reflect a guided or coordinated effort to resolve unanswered issues. The notion that hypertension is polygenic is reinforced, yet few data are provided as to the actual number of genes involved, gene-gene interaction or gene-environment interaction. Advanced biotechnological tools involving transcriptomics and proteomics are underused. Research on the genetic basis of hypertension has generated over the past year a large number of candidate genes and tied them to various aspects of hypertension. How these genes fit into the complex pathophysiological network that induces hypertension remains unclear. The task of putting together these genes into a cohesive framework still lies ahead, but promises to enlighten us as to the true nature of hypertension, the pathogenic mechanisms involved and improved therapeutic and preventive measures.

Background: Increased risks of cardiac morbidity and mortality among childhood cancer survivors have been described previously. However, little is known about the very long-term risks of cardiac mortality and whether the risk has decreased among those more recently diagnosed. We investigated the risk of long-term cardiac mortality among survivors within the recently extended British Childhood Cancer Survivor Study. Methods: The British Childhood Cancer Survivor Study is a population-based cohort of 34 489 five-year survivors of childhood cancer diagnosed from 1940 to 2006 and followed up until February 28, 2014, and is the largest cohort to date to assess late cardiac mortality. Standardized mortality ratios and absolute excess risks were used to quantify cardiac mortality excess risk. Multivariable Poisson regression models were used to evaluate the simultaneous effect of risk factors. Likelihood ratio tests were used to test for heterogeneity and trends. Results: Overall, 181 cardiac deaths were observed, which was 3.4 times that expected. Survivors were 2.5 times and 5.9 times more at risk of ischemic heart disease and cardiomyopathy/heart failure death, respectively, than expected. Among those >60 years of age, subsequent primary neoplasms, cardiac disease, and other circulatory conditions accounted for 31%, 22%, and 15% of all excess deaths, respectively, providing clear focus for preventive interventions. The risk of both overall cardiac and cardiomyopathy/heart failure mortality was greatest among those diagnosed from 1980 to 1989. Specifically, for cardiomyopathy/heart failure deaths, survivors diagnosed from 1980 to 1989 had 28.9 times the excess number of deaths observed for survivors diagnosed either before 1970 or from 1990 on. Conclusions: Excess cardiac mortality among 5-year survivors of childhood cancer remains increased beyond 50 years of age and has clear messages in terms of prevention strategies. However, the fact that the risk was greatest in

We sought to determine the long-term outcome of high-risk patients who underwent transcatheter aortic valve replacement (TAVR) with first-generation devices with a focus on the identification of predictors for mortality and valve durability. Consecutive patients in our prospective single-centre registry undergoing TAVR with first-generation devices (n=214 CoreValve; n=86 SAPIEN) between 06/2007 and 07/2009 were retrospectively analysed (n=300, mean age 81.43±6.55 years, mean STS score 6.5±4.5%). Kaplan-Meier estimates of survival and the Cox proportional hazards model were used to identify independent predictors of all-cause-mortality. At 1, 5, and 7 years, estimated survival rates were 76.0%, 40.2%, and 23.2%, respectively. Age-adjusted baseline predictors of mortality included atrial fibrillation, impaired kidney function, peripheral artery disease, and mitral regurgitation (≥moderate). Baseline risk-adjusted procedure-related predictors for all-cause mortality included acute kidney injury, neurological events, major vascular complications, and major/life-threatening bleeding. At both five and six years, 78.2% of surviving patients were in NYHA Class I or II. PVL was ≤mild in the majority of patients at discharge and throughout follow-up. At seven years, the overall crude cumulative incidence of structural valve deterioration according to the 2017 EAPCI/ESC/EACTS definition was 14.9% (CoreValve 11.8% vs. SAPIEN 22.6%; p=0.01). Seven years after TAVR, 23.2% of high-risk patients were still alive. Independent predictors of all-cause mortality included both patient- and procedure-related factors. With a cumulative incidence of 14.9% at seven years, there is some suggestion that SVD post TAVR may become increasingly relevant during longer-term follow-up.

Port-wine stain (PWS) is still a challenging condition for clinician to treat, because in the majority of cases, the stains are not lifted fully by treatment with laser therapy. Photodynamic therapy (PDT) was considered recently as a promising alternative treatment for PWS. We report here long-term follow-up measures 18 years on PWS lesion treated with PDT and the histological data of residual PWS. Copyright © 2014 Elsevier B.V. All rights reserved.

Due to demographic changes in average life expectancy the age of patients undergoing cardiac surgery is increasing as well. We have reviewed the short- and long-term outcome in patients over 80 years of age after aortic valve replacement with or without concomitant coronary grafting. From 1.1.1995 until 31.12.1999, 126 patients (93 women, 33 men between 80 and 89 years, 82.8 +/- 2.4) underwent aortic valve replacement. 64 patients (group A) received isolated valve replacement, 62 (group B) underwent myocardial revascularization as well. The 30-day hospital mortality rate was 6.3% for group A and 14.5% for group B. The follow-up time ranged between 3 and 63 months (32 +/- 16). None of the patients had to be reoperated for prosthetic valve dysfunction or endocarditis. Bleeding complications due to anticoagulation therapy were observed by one patient from group A 3 years after the operation. Of the 15 deaths during the follow-up period seven (47%) were cardiac in nature and two (13%) related to stroke. Acturial survival rates for group A were 89%, 85% and 77% at 1, 2 and 3 years, and for group B 76%, 72% and 70%. Permanent nursing care was not required 1 year after the operation by 100% of patients in group A (2 years: 98%, 3 years 95%) and by 100% of patients in group B (2 years: 93%, 3 years: 90%). At an interval of 1 year after the operation 96% of patients in group A had not been hospitalized as a result of cardiac disorders (2 years: 96%, 3 years: 94%). The rates for group B were 88%, 81% and 75%. Compared with younger age groups, aortic valve replacement in patients 80 years of age and older is associated with a distinctly increased mortality and morbidity. However, our data suggest that considering the poor prognosis of conservative therapy of symptomatic aortic valve disease, functional status as well as life expectancy in this age group seem to be positively influenced by aortic valve replacement.

San Francisco Bay (SFB), USA, is highly enriched in nitrogen and phosphorus, but has been resistant to the classic symptoms of eutrophication associated with over-production of phytoplankton. Observations in recent years suggest that this resistance may be weakening, shown by: significant increases of chlorophyll-a (chl-a) and decreases of dissolved oxygen (DO), common occurrences of phytoplankton taxa that can form Harmful Algal Blooms (HAB), and algal toxins in water and mussels reaching levels of concern. As a result, managers now ask: what levels of chl-a in SFB constitute tipping points of phytoplankton biomass beyond which water quality will become degraded, requiring significant nutrient reductions to avoid impairments? We analyzed data for DO, phytoplankton species composition, chl-a, and algal toxins to derive quantitative relationships between three indicators (HAB abundance, toxin concentrations, DO) and chl-a. Quantile regressions relating HAB abundance and DO to chl-a were significant, indicating SFB is at increased risk of adverse HAB and low DO levels if chl-a continues to increase. Conditional probability analysis (CPA) showed chl-a of 13 mg m-3 as a "protective" threshold below which probabilities for exceeding alert levels for HAB abundance and toxins were reduced. This threshold was similar to chl-a of 13-16 mg m-3 that would meet a SFB-wide 80% saturation Water Quality Criterion (WQC) for DO. Higher "at risk" chl-a thresholds from 25 to 40 mg m-3 corresponded to 0.5 probability of exceeding alert levels for HAB abundance, and for DO below a WQC of 5.0 mg L-1 designated for lower South Bay (LSB) and South Bay (SB). We submit these thresholds as a basis to assess eutrophication status of SFB and to inform nutrient management actions. This approach is transferrable to other estuaries to derive chl-a thresholds protective against eutrophication.

Evaluating the long-term hydrology of an evapotranspiration-capillary barrier with a 1000 year design life

2016-06-01

A surface barrier is a commonly used technology for isolation of subsurface contaminants. Surface barriers for isolating radioactive waste are expected to perform for centuries to millennia, yet there are very few data for field-scale surface barriers for periods approaching a decade or longer. The Prototype Hanford Barrier (PHB) with a design life of 1000 years was constructed over an existing radioactive waste site in 1994 to demonstrate its long-term performance. The primary element of the PHB is an evapotranspiration-capillary (ETC) barrier in which precipitation water is stored in a fine-textured soil layer and later released to the atmosphere via evapotranspiration. To address the barrier performance under extreme conditions, this study included an enhanced precipitation stress test from 1995 to 1997 to determine barrier response to extreme precipitation events. During this period a 1000 year 24 h return rainstorm was simulated in March every year. The loss of vegetation on barrier hydrology was tested with a controlled fire test in 2008. The 19 year monitoring record shows that the store-and-release mechanism worked as well as or better than the design criterion. Average drainage from the ETC barrier amounted to an average of 0.005 mm yr-1, which is well below the design criterion of 0.5 mm yr-1. After a simulated wildfire, the naturally reestablished vegetation and increased evaporation combined to release the stored water and summer precipitation to the atmosphere such that drainage did not occur in the 5 years subsequent to the fire.

Long-Term Exposure to High Altitude Affects Conflict Control in the Conflict-Resolving Stage

2015-01-01

The neurocognitive basis of the effect of long-term high altitude exposure on conflict control is unclear. Event related potentials (ERPs) were recorded in a flanker task to investigate the influence of high altitude on conflict control in the high-altitude group (who had lived at high altitude for three years but were born at low altitude) and the low-altitude group (living in low altitude only). Although altitude effect was not significant at the behavioral level, ERPs showed cognitive conflict modulation. The interaction between group and trial type was significant: P3 amplitude was greater in the low-altitude group than in the high-altitude group in the incongruent trial. This result suggests that long-term exposure to high altitude affects conflict control in the conflict-resolving stage, and that attentional resources are decreased to resist the conflict control in the high-altitude group.

To identify the types of early cranial ultrasound changes that were significant predictors of adverse outcome during the first year of life in asphyxiated term infants. This was a prospective cohort study. Shortly after birth, cranial ultrasonography was carried out via the anterior fontanelles of 70 normal control infants and 104 asphyxiated infants with a history of fetal distress and Apgar scores of less than 6 at 1 and 5 min of life, or requiring endotracheal intubation and manual intermittent positive pressure ventilation for at least 5 min after birth. Neurodevelopmental assessment was carried out on the survivors at 1 year of age. Abnormal cranial ultrasound changes were detected in a significantly higher proportion (79.8%, or n = 83) of asphyxiated infants than controls (39.5%, or n = 30) (P < 0.0001). However, logistic regression analysis showed that only three factors were significantly associated with adverse outcome at 1 year of life among the asphyxiated infants. These were: (i) decreasing birthweight (for every additional gram of increase in birthweight, adjusted odds ratio (OR) = 0.999, 95% confidence interval (CI) 0.998, 1.000; P = 0.047); (ii) a history of receiving ventilatory support during the neonatal period (adjusted OR = 8.3; 95%CI 2.4, 28.9; P = 0.0009); and (iii) hypoxic-ischaemic encephalopathy stage 2 or 3 (adjusted OR = 5.8; 95%CI 1.8, 18.6; P = 0.003). None of the early cranial ultrasound changes was a significant predictor. Early cranial ultrasound findings, although common in asphyxiated infants, were not significant predictors of adverse outcome during the first year of life in asphyxiated term infants.

Bone mineral density in girls with functional hypothalamic amenorrhea subjected to estroprogestagen treatment--a 4-year prospective study.

2011-11-01

The aim of this study was to evaluate the effects of 4-year estroprogestagen therapy (EP) on the bone mineral density (BMD) of 16- to 17-year-old girls with functional hypothalamic amenorrhea (FHA, n = 78). Baseline values of hormonal parameters, bone fraction of alkaline phosphatase (BALP), and cross-linked n-telopeptide of type I collagen (Ntx) were taken along with BMD measurements. Follow-up measurements of laboratory parameters were performed after 6 months of EP treatment. BMD was measured on a yearly basis. Six-month treatment resulted in a marked increase in estradiol levels and a significant decrease in BALP and Ntx. The relative increase in BMD was highest after the second year of treatment. Based on the dynamics of BMD changes during the first year of treatment, we identified a subgroup with no or insignificant reactions to the treatment. It was characterized by significantly higher baseline BMD and markedly lower baseline Ntx compared to the patients who responded to 1-year therapy well or extremely well. Further follow-up proved, however, that this subgroup did not differ significantly in terms of the long-term prognosis for BMD normalization. In conclusion, this study showed that EP therapy is effective in the treatment of BMD disorders associated with FHA.

Long-term benefit of liposuction in patients with lipoedema: a follow-up study after an average of 4 and 8 years.

Long-term results following liposuction in patients with lipoedema are available only for an average period of 4 years. To find out whether the improvement of complaints persists for a further 4 years. In a single-centre study, 85 patients with lipoedema had already been examined after 4 years. A mail questionnaire - often in combination with clinical controls - was repeated after another 4 years (8 years after liposuction). Compared with the results after 4 years, the improvement in spontaneous pain, sensitivity to pressure, oedema, bruising and restriction of movement persisted. The same held true for patient self-assessment of cosmetic appearance, quality of life and overall impairment. Eight years after surgery, the reduction in the amount of conservative treatment (combined decongestive therapy, compression garments) was similar to that observed 4 years earlier. These results demonstrate for the first time the long-lasting positive effects of liposuction in patients with lipoedema. © 2015 British Association of Dermatologists.

Little is known about the genetic basis of convergent traits that originate repeatedly over broad taxonomic scales. The myogenic electric organ has evolved six times in fishes to produce electric fields used in communication, navigation, predation, or defense. We have examined the genomic basis of the convergent anatomical and physiological origins of these organs by assembling the genome of the electric eel (Electrophorus electricus) and sequencing electric organ and skeletal muscle transcriptomes from three lineages that have independently evolved electric organs. Our results indicate that, despite millions of years of evolution and large differences in the morphology of electric organ cells, independent lineages have leveraged similar transcription factors and developmental and cellular pathways in the evolution of electric organs.

The function of verbal short-term memory is supported not only by the phonological loop, but also by semantic resources that may operate on both short and long time scales. Elucidation of the neural underpinnings of these mechanisms requires effective behavioral manipulations that can selectively engage them. We developed a novel cued sentence recall paradigm to assess the effects of two factors on sentence recall accuracy at short-term and long-term stages. Participants initially repeated auditory sentences immediately following a 14-s retention period. After this task was complete, long-term memory for each sentence was probed by a two-word recall cue. The sentences were either concrete (high imageability) or abstract (low imageability), and the initial 14-s retention period was filled with either an undemanding finger-tapping task or a more engaging articulatory suppression task (Exp. 1, counting backward by threes; Exp. 2, repeating a four-syllable nonword). Recall was always better for the concrete sentences. Articulatory suppression reduced accuracy in short-term recall, especially for abstract sentences, but the sentences initially recalled following articulatory suppression were retained better at the subsequent cued-recall test, suggesting that the engagement of semantic mechanisms for short-term retention promoted encoding of the sentence meaning into long-term memory. These results provide a basis for using sentence imageability and subsequent memory performance as probes of semantic engagement in short-term memory for sentences.

Background Treatment decisions for older patients with type 2 diabetes mellitus must balance glycemic control and adverse event risk. The objective of this study was to evaluate the long-term safety and tolerability of saxagliptin 5 mg as add-on therapy to common antihyperglycemic drugs in patients aged ≥65 years and <65 years. Methods Pooled adverse event data from three placebo-controlled trials of 76–206 weeks’ duration in older (≥65 years) and younger (<65 years) patients receiving saxagliptin 5 mg or matching placebo added to metformin, glyburide, or a thiazolidinedione were analyzed. Measurements were calculated from day of first dose to specified event or last dose and included time at risk for adverse events, treatment-related adverse events, serious adverse events, adverse events leading to discontinuation, and events of special interest. Weighted incidence rates (number of events/total time) and incidence rate ratios (saxagliptin/placebo) with 95% confidence intervals were calculated (Mantel-Haenszel test). Results A total of 205 older (mean age 69 years; saxagliptin, n=99; placebo, n=106) and 1,055 younger (mean age 52 years; saxagliptin, n=531; placebo, n=524) patients were assessed. Regardless of age category, the adverse event incidence rates were generally similar between treatments, with confidence intervals for incidence rate ratios bridging 1. Treatment-related adverse events occurred in 36 older patients receiving saxagliptin versus 32 receiving placebo (incidence rate 34.1 versus 27.1 per 100 person-years) and in 150 younger patients in both treatment groups (incidence rate 24.0 versus 27.8 per 100 person-years). With saxagliptin versus placebo, serious adverse events occurred in eight versus 14 older (incidence rate 5.7 versus 9.9 per 100 person-years) and 49 versus 44 younger patients (incidence rate 6.5 versus 6.6 per 100 person-years). There were two deaths (one patient ≥65 years) with saxagliptin and six (none aged ≥65 years

Altered brain volumes and associations between volumes and developmental outcomes have been reported in prematurely born children. To assess which regional brain volumes are different in very low birth weight (VLBW) children without neurodevelopmental impairments ([NDI] cerebral palsy, hearing loss, blindness and significantly delayed cognitive performance) compared with VLBW children with NDI, and to evaluate the association between regional brain volumes at term-equivalent age and cognitive development and neurological performance at a corrected age of 2 years. The study group consisted of a regional cohort of 164 VLBW children, divided into one group of children without NDI (n = 148) and one group of children with NDI (n = 16). Brain (MRI) was performed at term-equivalent age, from which brain volumes were manually analysed. Cognitive development was assessed with the Bayley Scales of Infant Development II (BSID-II), and neurological performance with the Hammersmith Infant Neurological Examination at the corrected age of 2 years. The volumes of total brain tissue, cerebrum, frontal lobes, basal ganglia and thalami, and cerebellum were significantly smaller, and the volume of the ventricles significantly larger, in the children with NDI than in those without NDI. Even in children without NDI, a smaller cerebellar volume was significantly correlated with poor neurological performance at 2 years of corrected age. Volumetric analysis at brain MRI can provide an additional parameter for early prediction of outcome in VLBW children.

Chances of short-term cooling trends over Canada for the next decades

2014-05-01

As climate services continue to develop in Quebec, Canada, an increasing number of requests are made for providing information relevant for the near term. As a response, one approach has been to consider short-term cooling trends as a basis for climate products. This project comprises different aspects: technical steps, knowledge transfer, and societal use. Each step does represent a different challenge. The technical part, i.e. producing probabilistic distributions of short-term temperature trends, involves relatively complex scenario construction methods including bias-related post-processing, and access to wide simulation and observation databases. Calculations are performed on 60 CMIP5-based scenarios on a grid covering Canada during the period 2006-2035, and for 5, 10, 15, 20 and 25-year trend durations. Knowledge transfer implies overcoming misinterpretation, given that probabilistic projections based on simulation ensembles are not perfectly related to real-Earth possible outcomes. Finally, societal use of this information remains the biggest challenge. On the one hand, users clearly state their interest in near-term relevant information, and intuitively it seems clear that short-term cooling trends embedded within the long-term warming path should be considered in adaptation plans, for avoiding over-adaptation. On the other hand, the exact way of incorporating such information within a decision-making process has proven not to be obvious. Irrespective of that, the study and communication of short-term cooling chances is necessary for preventing decision-makers to infer from the eventual occurrence of such a trend that global warming isn't happening. The presentation will discuss the three aspects aforementioned.

Leadership in workplace health promotion projects: 1- and 2-year effects on long-term work attendance.

Despite the acknowledged role of leadership in the psychosocial work environment, few studies focus on how leadership qualities and strategies may act as key processes of importance to positive effects of workplace health promotion (WHP). The aim of this study was to increase knowledge about how leadership qualities and strategies in WHP projects influence employees' long-term work attendance. The 1- and 2-year effect of leadership on the prevalence of long-term work attendance among municipal human service workers (n = 3 275) was analysed using 3-year register-based data on sick leave, questionnaires and a qualitative categorization of each unit. Increased leadership qualities, especially where leaders used rewards, recognition and respect, were associated with higher prevalence of work attendance at follow-up [PR 1.42 (1.20-1.69)]. Leaders' strategies and views on work-related health had a significant impact on increased work attendance in projects that had goals clearly focusing on changeable factors [1.36 (1.11-1.67)], in multi-focused projects [1.60 (1.24-2.04)] and in projects aimed to increase employees' awareness of their health. Workplace health promotion strategies with a single focus on strengthening individual, professional or organizational resources were negatively associated with work attendance. A higher proportion of employee work attendance was also seen in units whose leaders viewed the organization or the society (rather than individual workers) as responsible for the high rate of sick leave. Leadership, WHP strategies and leaders' attitudes towards employee work-related health have importance for implementation processes, as well as affecting employee work attendance. In this study, multi-focused WHP interventions had the largest effect on work attendance.

A Unified Development of Basis Reduction Methods for Rotor Blade Analysis

NASA Technical Reports Server (NTRS)

Ruzicka, Gene C.; Hodges, Dewey H.; Rutkowski, Michael (Technical Monitor)

2001-01-01

The axial foreshortening effect plays a key role in rotor blade dynamics, but approximating it accurately in reduced basis models has long posed a difficult problem for analysts. Recently, though, several methods have been shown to be effective in obtaining accurate,reduced basis models for rotor blades. These methods are the axial elongation method,the mixed finite element method, and the nonlinear normal mode method. The main objective of this paper is to demonstrate the close relationships among these methods, which are seemingly disparate at first glance. First, the difficulties inherent in obtaining reduced basis models of rotor blades are illustrated by examining the modal reduction accuracy of several blade analysis formulations. It is shown that classical, displacement-based finite elements are ill-suited for rotor blade analysis because they can't accurately represent the axial strain in modal space, and that this problem may be solved by employing the axial force as a variable in the analysis. It is shown that the mixed finite element method is a convenient means for accomplishing this, and the derivation of a mixed finite element for rotor blade analysis is outlined. A shortcoming of the mixed finite element method is that is that it increases the number of variables in the analysis. It is demonstrated that this problem may be rectified by solving for the axial displacements in terms of the axial forces and the bending displacements. Effectively, this procedure constitutes a generalization of the widely used axial elongation method to blades of arbitrary topology. The procedure is developed first for a single element, and then extended to an arbitrary assemblage of elements of arbitrary type. Finally, it is shown that the generalized axial elongation method is essentially an approximate solution for an invariant manifold that can be used as the basis for a nonlinear normal mode.

Mitral valve repair is considered the gold standard in surgery of degenerative mitral valve insufficiency (MVI), but the long-term results (>20 years) are unknown. We reviewed the first 162 consecutive patients who underwent mitral valve repair between 1970 and 1984 for MVI due to nonrheumatic disease. The cause of MVI was degenerative in 146 patients (90%) and bacterial endocarditis in 16 patients (10%). MVI was isolated or, in 18 cases, associated with tricuspid insufficiency. The mean age of the 162 patients (104 men and 58 women) was 56+/-10 years (age range 22 to 77 years). New York Heart Association functional class was I, II, III, and IV in 2%, 39%, 52%, and 7% of patients, respectively. The mean cardiothoracic ratio was 0.58+/-0.07 (0.4 to 0.8), and 72 (45%) patients had atrial fibrillation. Valve analysis showed that the main mechanism of MVI was type II Carpentier's functional classification in 152 patients. The leaflet prolapse involved the posterior leaflet in 93 patients, the anterior leaflet in 28 patients, and both leaflets in 31 patients. Surgical technique included a Carpentier's ring annuloplasty in all cases, a valve resection in 126 patients, and shortening or transposition of chordae in 49 patients. During the first postoperative month, there were 3 deaths (1.9%) and 3 reoperations (2 valve replacements and 1 repeat repair [1.9%]). Six patients were lost to follow-up. The remaining 151 patients with mitral valve repair were followed during a median of 17 years (range 1 to 29 years; 2273 patient-years). The 20-year Kaplan-Meier survival rate was 48% (95% CI 40% to 57%), which is similar to the survival rate for a normal population with the same age structure. The 20-year rates were 19.3% (95% CI 11% to 27%) for cardiac death and 26% (95% CI 17% to 35%) for cardiac morbidity/mortality (including death from a cardiac cause, stroke, and reoperation). During the 20 years of follow-up, 7 patients were underwent surgery at 3, 7, 7, 8, 8, 10, or 12

To evaluate the prognostic effect of changes in physical function at different intervals over the prior year on subsequent outcomes after accounting for present function. Prospective longitudinal study. Greater New Haven, Connecticut, from March 1998 to January 2006. Community-living persons aged 71 and older who completed an 18-month comprehensive assessment (N=658). Disability in 13 activities of daily living, instrumental activities of daily living, and mobility activities was assessed at the 18-month comprehensive assessment and at 12, 6, and 3 months before 18 months. Time to death and long-term nursing home admission, defined as 3 months and longer, were ascertained for up to 5 years after 18 months. In the bivariate models, disability at 18 months and change in disability between 18 months and each of the 3 prior time-points (12, 6, 3 months) were significantly associated with time to death. The risk of death, for example, increased by 24% for each 1-point increase in 18-month disability score (on a scale from 0 to 13) and by 22% for each 1-point change in disability score between 18 months and prior 12 months (on a scale from -13 to 13). In a set of multivariable models with and without covariates, the associations were maintained for 18-month disability but not for change in disability between 18 months and each of the 3 prior time-points. The results were comparable for time to long-term nursing home admission except that 2 of the associations were not statistically significant. When evaluating risk of adverse outcomes, such as death and long-term nursing home admission, an assessment of change in physical function at different intervals over the prior year, although a strong bivariate predictor, did not provide useful prognostic information beyond that available from current level of function. © 2018, Copyright the Authors Journal compilation © 2018, The American Geriatrics Society.

Local technicians in long-term research projects: evaluation of 25 years experience in an active tropical research station.

Most field ecology is conceived and financed by scientists from urban areas but is actually carried out in rural areas. Field staff can either be imported from urban areas or recruited from local residents. We evaluated the advantages and disadvantages of involving rural residents as local technicians over a 25- year period at active field research site in Costa Rica. We defined "local technicians" as local residents with no university education who acquired significant experience in field data collection, data management and/or laboratory work. We analyzed the experiences of incorporating these technicians into field research in developing countries from the points of view of scientist and of the local technicians themselves. Primary data were written responses from to a standardized survey of 19 senior scientists and Ph.D. students,and results from standardized personal interviews with 22 local technicians. Researchers highlighted the advantages of highly-skilled technicians with minimal staff turnover, as well as the technicians' knowledge of local ecological conditions. Local technicians considered the primary advantages of their jobs to be opportunities for continuing education training in science as well as cultural enrichment through interactions with people of different cultures. The main challenges identified by researchers were the lack of long-term funding for projects and extended training required for local technicians. Local technicians can be of great benefit to research projects by providing high-quality data collection at reasonable costs with low staff turnover. Over the last 25 years the research model at the field station we studied has evolved to the point that most long-term projects now depend heavily on local technicians. This model of involving local technicians in long-term research has multiple benefits for the researchers, the technicians and the local community, and could be adapted to a variety of settings in rural areas of developing

Comparison of different eigensolvers for calculating vibrational spectra using low-rank, sum-of-product basis functions

NASA Astrophysics Data System (ADS)

Leclerc, Arnaud; Thomas, Phillip S.; Carrington, Tucker

2017-08-01

Vibrational spectra and wavefunctions of polyatomic molecules can be calculated at low memory cost using low-rank sum-of-product (SOP) decompositions to represent basis functions generated using an iterative eigensolver. Using a SOP tensor format does not determine the iterative eigensolver. The choice of the interative eigensolver is limited by the need to restrict the rank of the SOP basis functions at every stage of the calculation. We have adapted, implemented and compared different reduced-rank algorithms based on standard iterative methods (block-Davidson algorithm, Chebyshev iteration) to calculate vibrational energy levels and wavefunctions of the 12-dimensional acetonitrile molecule. The effect of using low-rank SOP basis functions on the different methods is analysed and the numerical results are compared with those obtained with the reduced rank block power method. Relative merits of the different algorithms are presented, showing that the advantage of using a more sophisticated method, although mitigated by the use of reduced-rank SOP functions, is noticeable in terms of CPU time.

The cellular and molecular basis of long-term memory in vertebrates remains poorly understood. Knowledge regarding long-term memory has been impeded by the enormous complexity of the vertebrate brain, particularly the mammalian brain, as well as by the relative complexity of the behavioral alterations examined in most studies of long-term memory in vertebrates. Here, we demonstrate a long-term form of nonassociative learning—specifically, long-term habituation (LTH)—of a simple reflexive escape response, the C-start, in zebrafish larvae. The C-start is triggered by the activation of one of a pair of giant neurons in the zebrafish’s hindbrain, the Mauthner cells. We show that LTH of the C-start requires the activity of NMDA receptors and involves macromolecular synthesis. We further show that the long-term habituated reflex can by rapidly dishabituated by a brief tactile stimulus. Our results set the stage for rigorous, mechanistic investigations of the long-term memory for habituation of a reflexive behavioral response, one that is mediated by a relatively simple, neurobiologically tractable, neural circuit. Moreover, the demonstration of NMDAR and transcriptionally dependent LTH in a translucent vertebrate organism should facilitate the use of optical recording, and optogenetic manipulation, of neuronal activity to elucidate the cellular basis of a long-term vertebrate memory.

Near-Term Actions to Address Long-Term Climate Risk

NASA Astrophysics Data System (ADS)

Lempert, R. J.

2014-12-01

Addressing climate change requires effective long-term policy making, which occurs when reflecting on potential events decades or more in the future causes policy makers to choose near-term actions different than those they would otherwise pursue. Contrary to some expectations, policy makers do sometimes make such long-term decisions, but not as commonly and successfully as climate change may require. In recent years however, the new capabilities of analytic decision support tools, combined with improved understanding of cognitive and organizational behaviors, has significantly improved the methods available for organizations to manage longer-term climate risks. In particular, these tools allow decision makers to understand what near-term actions consistently contribute to achieving both short- and long-term societal goals, even in the face of deep uncertainty regarding the long-term future. This talk will describe applications of these approaches for infrastructure, water, and flood risk management planning, as well as studies of how near-term choices about policy architectures can affect long-term greenhouse gas emission reduction pathways.

Sparse-grid, reduced-basis Bayesian inversion: Nonaffine-parametric nonlinear equations

We extend the reduced basis (RB) accelerated Bayesian inversion methods for affine-parametric, linear operator equations which are considered in [16,17] to non-affine, nonlinear parametric operator equations. We generalize the analysis of sparsity of parametric forward solution maps in [20] and of Bayesian inversion in [48,49] to the fully discrete setting, including Petrov–Galerkin high-fidelity (“HiFi”) discretization of the forward maps. We develop adaptive, stochastic collocation based reduction methods for the efficient computation of reduced bases on the parametric solution manifold. The nonaffinity and nonlinearity with respect to (w.r.t.) the distributed, uncertain parameters and the unknown solution is collocated; specifically, by themore » so-called Empirical Interpolation Method (EIM). For the corresponding Bayesian inversion problems, computational efficiency is enhanced in two ways: first, expectations w.r.t. the posterior are computed by adaptive quadratures with dimension-independent convergence rates proposed in [49]; the present work generalizes [49] to account for the impact of the PG discretization in the forward maps on the convergence rates of the Quantities of Interest (QoI for short). Second, we propose to perform the Bayesian estimation only w.r.t. a parsimonious, RB approximation of the posterior density. Based on the approximation results in [49], the infinite-dimensional parametric, deterministic forward map and operator admit N-term RB and EIM approximations which converge at rates which depend only on the sparsity of the parametric forward map. In several numerical experiments, the proposed algorithms exhibit dimension-independent convergence rates which equal, at least, the currently known rate estimates for N-term approximation. We propose to accelerate Bayesian estimation by first offline construction of reduced basis surrogates of the Bayesian posterior density. The parsimonious surrogates can then be employed for online

Psychopathy: clinical features, developmental basis and therapeutic challenges.

Psychopathy is a personality disorder characterized by deficits in personality and behaviour. Personality deficits are marked by interpersonal and affective facets, including pathological lying, grandiose sense of self-worth, lack of remorse and callousness. Behavioural deficits are defined by lifestyle and antisocial deficits, including impulsivity, parasitic lifestyle and poor behavioural controls. The objective of this review is to provide clinicians with (i) an appreciation of the clinical features of psychopathy, (ii) an understanding of the structural and functional derangements and the genetic and environmental factors which serve as the basis for the development of psychopathy and (iii) a summary of published reports of pharmacological approaches to the management of this disorder. A literature search of MEDLINE/PubMed (1966-present) was conducted using the MeSH search terms psychopathy and antisocial personality disorder alone and in combination with the subheading drug therapy. Additional databases included Web of Science (1945-present) and International Pharmaceutical Abstracts (1970-present) using the text words psychopath and antisocial personality were searched. A search of Amazon books using the search terms psychopathy and sociopathy was also performed. Bibliographies of relevant articles were searched for additional citations. All data sources in English were considered for inclusion. For background information, broad subject headings were searched for review articles first. Human and animal drug therapy articles were evaluated giving preference to those papers using a controlled trial methodology. Psychopathy is a personality disorder characterized by a lack of conscience, pathologic lying, manipulative behaviour and often superficial charm. The incidence of psychopathy in the general population is generally considered to be 0·6-4% with a higher proportion of males to females.

Enucleation is increasingly used for pancreatic solid pseudopapillary neoplasm (SPN) to preserve function of the pancreas. The data was limited due to rarity of this low-grade neoplasm. We sought to describe the indications, operative technique, short and long-term outcomes after enucleation with largest series of enucleated SPNs. Data collected retrospectively from 110 patients with SPN who underwent pancreatectomy between 2009 and 2016 in our institution were reviewed. Thirty-one patients underwent enucleation were identified for analysis, and compared with the 70 patients underwent conventional pancreatic resection. Of the 31 patients, 27 (87.1%) were women, and the mean age was 29.8 years (range, 11-49 years). Enucleated SPNs were mostly located in the head/uncinate process of the pancreas (38.7%). Overall morbidity was 25.8%, mainly due to POPF (19.4%), and severe morbidity was only 6.5% with no death. Compared with conventional pancreatic resection, enucleation had a shorter duration of surgery (P < 0.001), less blood loss (P < 0.001), lower rate of exocrine insufficiency (P = 0.033) and comparable morbidity (P = 1), with no increased risk of tumor recurrence (P = 1). The rate of endocrine insufficiency after enucleation seemed lower (Nil vs. 4.5%, P = 0.55). Enucleation of SPN of the pancreas appears to be feasible and safe for preserving exocrine and endocrine function of the gland. Enucleation with negative surgical margin seems adequate with no increased risk of tumor recurrence. Enucleation could be seriously considered as an alternative to conventional resection for this frequently young population. Copyright © 2018. Published by Elsevier Ltd.

Fatigue in prostate cancer patients treated with external beam radiotherapy: a prospective 5-year long-term patient-reported evaluation.

PubMed

Fransson, Per

2010-01-01

Limited information is available regarding the long-term effect of external beam radiotherapy (EBRT) on fatigue in individuals with prostate cancer (PC). Men with PC treated with EBRT from January 1992 to June 2003 were enrolled in a prospective study. The QLQ-C30 questionnaire was used to evaluate pre-treatment fatigue and up to 5 years post-treatment. 407 men with 5-year assessments were analyzed. Fatigue increased between pre-treatment (mean: 15.5; CI: 13.6-17.4) and 5-years post-treatment (mean: 22.8; CI: 20.5-25.1; P<0.001). Pre-treatment fatigue was absent in 206/407 (59%) patients and 5-year post-treatment was reported by 264/407 (66%). Sixteen of 407 patients (4%) reported severe fatigue after 5 years. Physical-, emotional-, cognitive function, and dyspnea were the factors that correlated most to higher level of fatigue 5-year post-treatment. Fatigue is a common symptom among patients with PC. A large percentage of patients reported pre-treatment fatigue. Fatigue increased over time, with the highest level seen at the end of EBRT. Severe fatigue was reported by 4% 5-year post-treatment. More work is needed in order to identify which patients are most susceptible to developing fatigue especially during radiotherapy.

Toward a Neural Basis for Social Behavior

Nearly 25 years ago, the shared interests of psychologists and biologists in understanding the neural basis of social behavior led to the inception of social neuroscience. In the past decade, this field has exploded, in large part due to the infusion of studies that use fMRI. At the same time, tensions have arisen about how to prioritize a diverse range of questions and about the authority of neurobiological data in answering them. The field is now poised to tackle some of the most interesting and important questions about human and animal behavior but at the same time faces uncertainty about how to achieve focus in its research and cohesion among the scientists who tackle it. The next 25 years offer the opportunity to alleviate some of these growing pains, as well as the challenge of answering large questions that encompass the nature and bounds of diverse social interactions (in humans, including interactions through the internet); how to characterize, and treat, social dysfunction in psychiatric illness; and how to compare social cognition in humans with that in other animals.

In 2012, we witnessed a resurgence of West Nile virus (WNV) in the United States, with the largest outbreak of human cases reported since 2003. WNV is now endemic and will continue to produce epidemics over time, therefore defining the long-term consequences of WNV infection is critical. Over a period of eight years, we prospectively followed a cohort of 157 WNV-infected subjects in the Houston metropolitan area to observe recovery over time and define the long-term clinical outcomes. We used survival analysis techniques to determine percentage of recovery over time and the effects of demographic and co-morbid conditions on recovery. We found that 40% of study participants continued to experience symptoms related to their WNV infection up to 8 years later. Having a clinical presentation of encephalitis and being over age 50 were significantly associated with prolonged or poor recovery over time. Since the health and economic impact as a result of prolonged recovery, continued morbidity, and related disability is likely substantial in those infected with WNV, future research should be aimed at developing effective vaccines to prevent illness and novel therapeutics to minimize morbidity, mortality, and long-term complications from infection.

This study was designed to determine whether long-term (2 years) brain exposure to mobile telephone radiofrequency (RF) fields produces any astrocytic activation as these glia react to a wide range of neural perturbations by astrogliosis. Using a purpose-designed exposure system at 900 MHz, mice were given a single, far-field whole body exposure at a specific absorption rate of 4 W/kg on five successive days per week for 104 weeks. Control mice were sham-exposed or freely mobile in a cage to control any stress caused by immobilization in the exposure module. Brains were perfusion-fixed with 4% paraformaldehyde and three coronal levels immunostained for glial fibrillary acidic protein (GFAP). These brain slices were then examined by light microscopy and the amount of this immunomarker quantified using a color deconvolution method. There was no change in astrocytic GFAP immunostaining in brains after long-term exposure to mobile telephony microwaves compared to control (sham-exposed or freely moving caged mice). It was concluded that long-term (2 years) exposure of murine brains to mobile telephone RF fields did not produce any astrocytic reaction (astrogliosis) detectable by GFAP immunostaining. © 2015 Wiley Periodicals, Inc.

We propose a convenient orthogonal basis of the Hilbert space for the quantum spin chain associated with the A2(2) algebra (or the Izergin-Korepin model). It is shown that compared with the original basis the monodromy-matrix elements acting on this basis take relatively simple forms, which is quite similar as that for the quantum spin chain associated with An algebra in the so-called F-basis. As an application of our general results, we present the explicit recursive expressions of the Bethe states in this basis for the Izergin-Korepin model.

Bariatric surgery for morbid obesity results in massive weight loss and improvement of health and quality of life. A downside of the major weight loss is the excess of overstretched skin, which may influence the patient's quality of life by causing functional and aesthetic problems. The purpose of the current study was to evaluate the patient's quality of life long-term after body contouring following bariatric surgery. Quality of life was measured with the Obesity Psychosocial State Questionnaire in 33 post-bariatric surgery patients 7.2 years (range, 3.2 to 13.3 years) after body contouring surgery. Data were compared with previous assessments 4.1 years (range, 0.7 to 9.2 years) after body contouring surgery of the quality of life at that time and before body contouring surgery. Compared with appraisals of quality of life before body contouring surgery, a significant, mostly moderate to large, sustained improvement of quality of life was observed in post-bariatric surgery patients 7.2 years after body contouring surgery in six of the seven psychosocial domains. A small deterioration occurred between 4.1- and 7.2-year follow-up on two of the seven domains except for the domain efficacy toward eating, which showed a significant improvement. At 7-year follow-up, 18 patients (55 percent) were satisfied with the result of body contouring surgery. This study indicates a sustained quality-of-life improvement in post-bariatric surgery patients after body contouring surgery. This suggests the importance of including reconstructive surgery as a component in the multidisciplinary approach in the surgical treatment of morbid obesity. Therapeutic, IV.

Mitral valve replacement using a bioprosthesis remains controversial in young patients because data on long-term outcomes are missing. This study evaluated the long-term results of the PERIMOUNT pericardial mitral bioprosthesis in patients aged 65 years or younger. From 1984 to 2010, 148 Carpentier-Edwards PERIMOUNT mitral bioprostheses were implanted in 148 patients aged 65 years or younger. Baseline clinical, perioperative and follow-up data were recorded prospectively. Structural valve deterioration (SVD) was defined by strict echocardiographic assessment. The mean follow-up period was 8.6 ± 5.5 years, for a total of 1269 valve-years. Operative mortality rate was 2.0%. Fifty-one late deaths occurred (linearized rate 4.0% per valve-year). Actuarial survival rates averaged 70 ± 4%, 53 ± 6% and 31 ± 7% after 10, 15 and 20 years of follow-up, respectively. Actuarial freedom from SVD at 10, 15 and 20 years was 78 ± 5%, 47 ± 7% and 19 ± 7%, respectively. Reoperation was associated with no operative mortality. Actuarial freedom from reoperation due to SVD at 10, 15 and 20 years was 82 ± 4%, 50 ± 6% and 25 ± 8%, respectively. Competing risk analysis demonstrated an actual risk of explantation secondary to SVD at 20 years of 44 ± 5%. Expected valve durability was 14.2 years for this age group. In the selected patients aged 65 years or younger undergoing mitral valve replacement with a pericardial bioprosthesis, the expected valve durability was 14.2 years. Reoperation for SVD was associated with a low risk of mortality. © The Author(s) 2018. Published by Oxford University Press on behalf of the European Association for Cardio-Thoracic Surgery.

We assessed brain metabolite levels by magnetic resonance spectroscopy (MRS) in 1-year-old infants born small at term, as compared with infants born appropriate for gestational age (AGA), and their association with neurodevelopment at 2 years of age. A total of 40 infants born small (birthweight <10th centile for gestational age) and 30 AGA infants underwent brain MRS at age 1 year on a 3-T scanner. Small-born infants were subclassified as late intrauterine growth restriction or as small for gestational age, based on the presence or absence of prenatal Doppler and birthweight predictors of an adverse perinatal outcome, respectively. Single-voxel proton magnetic resonance spectroscopy ((1)H-MRS) data were acquired from the frontal lobe at short echo time. Neurodevelopment was evaluated at 2 years of age using the Bayley Scales of Infant and Toddler Development, Third Edition, assessing cognitive, language, motor, social-emotional, and adaptive behavior scales. As compared with AGA controls, infants born small showed significantly higher levels of glutamate and total N-acetylaspartate (NAAt) to creatine (Cr) ratio at age 1 year, and lower Bayley Scales of Infant and Toddler Development, Third Edition scores at 2 years. The subgroup with late intrauterine growth restriction further showed lower estimated glutathione levels at age 1 year. Significant correlations were observed for estimated glutathione levels with adaptive scores, and for myo-inositol with language scores. Significant associations were also noticed for NAA/Cr with cognitive scores, and for glutamate/Cr with motor scores. Infants born small show brain metabolite differences at 1 year of age, which are correlated with later neurodevelopment. These results support further research on MRS to develop imaging biomarkers of abnormal neurodevelopment. Copyright © 2015 Elsevier Inc. All rights reserved.

Dimensioning the Term Carbenoid.

The current use of the term carbenoid is discussed, particularly in the context of carbene transfer reactions from diazo compounds, in which intermediates of type L n M=CR 1 R 2 , or one of its resonance forms, are tagged which such a name. We discuss this issue, on the basis of the data evidencing the metal-carbene nature of those intermediates, as well as the existence of carbenoids of type (N 2 )(M)CR 1 R 2 en route to the formation to L n M=CR 1 R 2' from diazo reagents. We propose the exclusive use of the carbenoid term to species of type (X)(M)CR 1 R 2 with a tetrasubstituted carbon center that upon loss of X afford an effective carbene transfer process. © 2017 Wiley-VCH Verlag GmbH & Co.

Remnant dimension is considered one of the crucial elements determining the success of sleeve gastrectomy (SG), and dilation of the gastric fundus is often believed to be the main cause of failure. The main outcome of this study is to find correlations between remnant morphology in the immediate post-operative stage, its dilation in years, and the long-term results. The second purpose aims to correlate preoperative eating disorders, taste alteration, hunger perception, and early satiety with post-SG results. Remnant morphology was evaluated, in the immediate post-operative stage and over the years (≥2 years), through X-ray of the oesophagus-stomach-duodenum calculating the surface in anteroposterior (AP) and right anterior oblique projection (RAO). Presurgery diagnosis of eating disorders and their evaluation through "Eating Disorder Inventory-3" (EDI3) during follow-up were performed. Change in taste perception, sense of appetite, and early satiety were evaluated. Patients were divided into two groups: "failed SGs (EWL<50%) and "efficient SGs" (EWL >50%). There were a total of 50 patients (37 F, 13 M), with mean age 52 years, preoperative weight 131 ± 21.8 kg, and BMI 47.4 ± 6.8 kg/m 2 . Post-operative remnant mean dimensions overlapped between the two groups. On a long-term basis, an increase of 57.2 and 48.4% was documented in the AP and RAO areas respectively. In "failed" SGs, dilation was significantly superior to "efficient" SGs (AP area 70.2 vs 46.1%; RAO area 59.3 vs 39%; body width 102% vs 41.7%). Preoperative eating disorders were more present in efficient SGs than in failed SGs with the exception of sweet eating. There were no significant changes to taste perception during follow-up. Fifty-two percent of efficient SGs vs 26% of failed SGs reported a persistent lack of sense of hunger; similarly, 92.5 vs 78% declared the persistence of a sense of early satiety. The two groups did not statistically differ as far as all the variables of the EDI3

Quality of life and physical activity in long-term (≥5 years post-diagnosis) colorectal cancer survivors - systematic review.

Due to the increasing number of long-term (≥5 years post diagnosis) colorectal cancer survivors, long-term quality of life of these patients is highly relevant. Several studies have reported a positive association between physical activity and quality of life in colorectal cancer survivors, however, so far no systematic review has been published which focuses on long-term colorectal cancer survivors. A systematic review was conducted using the databases PubMed, Web of Science, PsychINFO, and CINAHL. Studies which investigated associations between physical activity and quality of life in long-term colorectal cancer survivors were included. Ten articles based on seven studies were identified. Long-term colorectal cancer survivors who were physically active reported better quality of life than long-term survivors who were not physically active. Both, moderate to vigorous physical activity and lower levels like light physical activity were associated with higher quality of life. Most studies assessed the association between physical activity and quality of life cross-sectionally but one prospective study which measured physical activity and quality of life at three different points in time also found associations between physical activity and quality of life. The association between physical activity and quality of life seemed to be stronger among women than among men. The findings of this systematic review support an association between physical activity and quality of life in long-term colorectal cancer survivors. However, the evidence is limited as most studies were based on cross-sectional and observational design.

Unraveling the neural basis of insect navigation.

PubMed

Heinze, Stanley

2017-12-01

One of the defining features of animals is their ability to navigate their environment. Using behavioral experiments this topic has been under intense investigation for nearly a century. In insects, this work has largely focused on the remarkable homing abilities of ants and bees. More recently, the neural basis of navigation shifted into the focus of attention. Starting with revealing the neurons that process the sensory signals used for navigation, in particular polarized skylight, migratory locusts became the key species for delineating navigation-relevant regions of the insect brain. Over the last years, this work was used as a basis for research in the fruit fly Drosophila and extraordinary progress has been made in illuminating the neural underpinnings of navigational processes. With increasingly detailed understanding of navigation circuits, we can begin to ask whether there is a fundamentally shared concept underlying all navigation behavior across insects. This review highlights recent advances and puts them into the context of the behavioral work on ants and bees, as well as the circuits involved in polarized-light processing. A region of the insect brain called the central complex emerges as the common substrate for guiding navigation and its highly organized neuroarchitecture provides a framework for future investigations potentially suited to explain all insect navigation behavior at the level of identified neurons.

Edifoligide, an E2F transcription factor decoy, does not prevent vein graft failure or adverse clinical outcomes at 1 year in patients undergoing coronary artery bypass grafting (CABG). We compared the 5-year clinical outcomes of patients in PREVENT IV treated with edifoligide and placebo to identify predictors of long-term clinical outcomes. A total of 3,014 patients undergoing CABG with at least 2 planned vein grafts were enrolled. Kaplan-Meier curves were generated to compare the long-term effects of edifoligide and placebo. A Cox proportional hazards model was constructed to identify factors associated with 5-year post-CABG outcomes. The main outcome measures were death, myocardial infarction (MI), repeat revascularization, and rehospitalization through 5 years. Five-year follow-up was complete in 2,865 patients (95.1%). At 5 years, patients randomized to edifoligide and placebo had similar rates of death (11.7% and 10.7%, respectively), MI (2.3% and 3.2%), revascularization (14.1% and 13.9%), and rehospitalization (61.6% and 62.5%). The composite outcome of death, MI, or revascularization occurred at similar frequency in patients assigned to edifoligide and placebo (26.3% and 25.5%, respectively; hazard ratio 1.03 [95% CI 0.89-1.18], P = .721). Factors associated with death, MI, or revascularization at 5 years included peripheral and/or cerebrovascular disease, time on cardiopulmonary bypass, lung disease, diabetes mellitus, and congestive heart failure. Up to a quarter of patients undergoing CABG will have a major cardiac event or repeat revascularization procedure within 5 years of surgery. Edifoligide does not affect outcomes after CABG; however, common identifiable baseline and procedural risk factors are associated with long-term outcomes after CABG. Copyright © 2012 Mosby, Inc.

Optimization of selected molecular orbitals in group basis sets.

PubMed

Ferenczy, György G; Adams, William H

2009-04-07

We derive a local basis equation which may be used to determine the orbitals of a group of electrons in a system when the orbitals of that group are represented by a group basis set, i.e., not the basis set one would normally use but a subset suited to a specific electronic group. The group orbitals determined by the local basis equation minimize the energy of a system when a group basis set is used and the orbitals of other groups are frozen. In contrast, under the constraint of a group basis set, the group orbitals satisfying the Huzinaga equation do not minimize the energy. In a test of the local basis equation on HCl, the group basis set included only 12 of the 21 functions in a basis set one might ordinarily use, but the calculated active orbital energies were within 0.001 hartree of the values obtained by solving the Hartree-Fock-Roothaan (HFR) equation using all 21 basis functions. The total energy found was just 0.003 hartree higher than the HFR value. The errors with the group basis set approximation to the Huzinaga equation were larger by over two orders of magnitude. Similar results were obtained for PCl(3) with the group basis approximation. Retaining more basis functions allows an even higher accuracy as shown by the perfect reproduction of the HFR energy of HCl with 16 out of 21 basis functions in the valence basis set. When the core basis set was also truncated then no additional error was introduced in the calculations performed for HCl with various basis sets. The same calculations with fixed core orbitals taken from isolated heavy atoms added a small error of about 10(-4) hartree. This offers a practical way to calculate wave functions with predetermined fixed core and reduced base valence orbitals at reduced computational costs. The local basis equation can also be used to combine the above approximations with the assignment of local basis sets to groups of localized valence molecular orbitals and to derive a priori localized orbitals.

An in-situ 13CO2 pulse-labeling experiment was carried out in a temperate heathland (8 oC MAT, 610 mm MAP) to study the impact on short-term carbon (C) allocation as affected by elevated CO2 concentration (+120 ppm), prolonged summer droughts (ca. -43 mm) and warming (+1 oC). The study was carried out six years after the climate treatments were initiated and took place in the early growing season in May in vegetation dominated by grasses, mainly Deschampsia flexuosa. Newly assimilated C (13C from the pulse-label) was traced into vegetation, soil and soil microorganisms and belowground respiration 1, 2 and 8 days after pulse-labeling. The importance of the microbial community in C utilization was investigated using 13C enrichment patterns in different microbial functional groups on the basis of phospholipid fatty acid (PLFA) profiles. Climate treatments did not affect microorganism abundance in soil or rhizosphere fractions in terms of total PLFA-C concentration. Elevated CO2 significantly reduced the abundance of gram-negative bacteria (17:0cy), but did not affect the abundance of decomposers (fungi and actinomycetes) in rhizosphere fractions. Drought favored the bacterial community in rhizosphere fractions whereas warming reduced the abundance of gram-negative bacteria (19:0cy) and changed the actinomycetes community (10Me16:0, 10Me18:0). Fastest and highest utilization of recently assimilated C was observed in rhizosphere associated gram-negative bacteria followed by gram-positive bacteria. The utilization of recently assimilated C by the microbial community was faster under elevated CO2 conditions compared to ambient. The 13C assimilation by green plant tissue and translocation to roots was significantly reduced by the extended summer drought. Under elevated CO2 conditions we observed an increased amount of 13C in the litter fraction. The assimilation of 13C by vegetation was not changed when the climate factors were applied in combination. The total amount of

Background: SUPPORT tools consist of 18 articles addressing the health policy-makers so that they can learn how to make evidence-informed health policies. These tools have been particularly recommended for developing countries. The present study tries to explain the process of evidence utilization for developing policy documents in the Iranian Ministry of Health and Medical Education (MoHME) and to compare the findings with those of SUPPORT tools. Methods: A qualitative research was conducted, using the framework analysis approach. Participants consisted of senior managers and technicians in MoHME. Purposeful sampling was done, with a maximum variety, for the selection of research participants: individuals having at least 5 years of experience in preparing evidence-based policy documents. Face-to-face interviews were conducted for data collection. As a guideline for the interviews, ‘the Utilization of Evidence in Policy-Making Organizations’ procedure was used. The data were analyzed through the analysis of the framework method using MAXQDA 10 software. Results: The participants acquired the research evidence in a topic-based form, and they were less likely to search on the basis of the evidence pyramid. To assess the quality of evidence, they did not use standard critical tools; to adapt the evidence and interventions with the local setting, they did not use the ideas and experiences of all stakeholders, and in preparing the evidence-based policy documents, they did not take into consideration the window of opportunity, did not refrain from using highly technical terms, did not write user-friendly summaries, and did not present alternative policy options. In order to develop health policies, however, they used the following innovations: attention to the financial burden of policy issues on the agenda, sensitivity analysis of the preferred policy option on the basis of technical, sociopolitical, and economic feasibility, advocacy from other scholars, using the

Patients with Parkinson disease (PD) commonly experience motor fluctuations and dyskinesias in response to oral dopaminergic medications. Affected patients may benefit from device-assisted therapy, such as medication infusion or deep brain stimulation surgery. This is the first Australian study of the long-term adherence to apomorphine infusion (AI) in patients with PD. To assess the adherence to AI in patients with PD in a single centre over a 10-year period and to find the reasons for discontinuation in patients who discontinued AI. This is an observational study of patients with PD treated with AI between 2004 and 2014. Outcome measures included changes in motor function and quality of life following AI, change in dose of other dopaminergic medications following AI, duration of infusion, adverse effects, reasons for cessation of AI and subsequent treatment after cessation. Mean duration of AI was 21.65 months. No patient achieved apomorphine monotherapy, and the mean reduction in the levodopa-equivalent dose of other dopaminergic medications after AI was 22.7%. The benefit of AI on motor function and quality of life was rated as 'much improved' or 'better' in 83% of patients. The most common reasons for discontinuation of AI were adverse effects and inadequate motor benefit. Most patients who discontinued AI were subsequently treated with another device-assisted therapy. AI is an effective therapy for severe motor response complications in PD, especially in the short and medium term. However, many patients cannot be maintained on AI in the longer term. © 2017 Royal Australasian College of Physicians.

2016-12-01

Acute kidney injury (AKI) is a common complication of medical and surgical interventions in hospitalized patients and associates with high mortality. Our aim was to examine renal recovery and long-term survival and time trends in AKI survival. Changes in serum creatinine (SCr) were used to define AKI in patients at Landspitali University Hospital in Iceland from 1993 to 2013. Renal recovery was defined as SCr < 1.5× baseline. Out of 25 274 individuals who had their highest measured SCr during hospitalization and an available baseline SCr, 10,419 (41%) had AKI during hospitalization (H-AKI), 19%, 11% and 12% with Stage 1, 2 and 3, respectively. The incidence of H-AKI increased from 18.6 (95% CI, 14.7-22.5) to 29.9 (95% CI, 26.7-33.1) per 1000 admissions/year over the study period. Survival after H-AKI was 61% at 90-days and 51% at one year. Comparing H-AKI patients to propensity score matched individuals the hazard ratio for death was 1.49 (1.36-1.62), 2.17 (1.95-2.41) and 2.95 (2.65-3.29) for Stage 1, 2 and 3, respectively. One-year survival of H-AKI patients improved from 47% in 1993-1997 to 57% in 2008-2013 and the adjusted hazard ratio for mortality improved, compared to the first 5-year period, 0.85 (0.81-0.89), 0.67 (0.64-0.71), and 0.57 (0.53-0.60) for each subsequent 5-year interval. Recovery of renal function was achieved in 88%, 58% and 44% of patients in Stages 1, 2 and 3, respectively, improving with time. Acute kidney injury is an independent predictor of long-term mortality in hospitalized patients but there has been a marked improvement in survival and renal recovery over the past two decades. © 2015 Asian Pacific Society of Nephrology.

Polyatomic molecular Dirac-Hartree-Fock calculations with Gaussian basis sets

NASA Technical Reports Server (NTRS)

Dyall, Kenneth G.; Faegri, Knut, Jr.; Taylor, Peter R.

1990-01-01

Numerical methods have been used successfully in atomic Dirac-Hartree-Fock (DHF) calculations for many years. Some DHF calculations using numerical methods have been done on diatomic molecules, but while these serve a useful purpose for calibration, the computational effort in extending this approach to polyatomic molecules is prohibitive. An alternative more in line with traditional quantum chemistry is to use an analytical basis set expansion of the wave function. This approach fell into disrepute in the early 1980's due to problems with variational collapse and intruder states, but has recently been put on firm theoretical foundations. In particular, the problems of variational collapse are well understood, and prescriptions for avoiding the most serious failures have been developed. Consequently, it is now possible to develop reliable molecular programs using basis set methods. This paper describes such a program and reports results of test calculations to demonstrate the convergence and stability of the method.

To assess the differential effect of personal and work-related psychosocial, physical and organizational determinants by gender on time to return-to-work (RTW) following long-term disability. Data come from a larger study conducted in the province of Quebec, Canada. A cohort of 455 adults on long-term disability due to work-related musculoskeletal disorders at the back/neck/upper limb was followed for 5 years through structured interviews and administrative databases. Left-truncated Cox regression modeling stratified by gender was used to assess time to a first partial or full RTW of at least 3 days. Survival curves of time to RTW were similar between men and women on long-term disability (log-rank test p value = 0.920) but many personal and occupational factors influencing RTW differed by gender. Women's risk factors included older age (HR = 0.734--in 10 years unit), poor to very poor perceived economic status (HR = 0.625), working ≥40 h/week and having dependents (HR = 0.508) and awareness of workplace-based occupational health and safety program (HR = 0.598); higher gross annual income (in $10,000 s) was a facilitator (HR = 1.225). In men, being over 55 years old (HR = 0.458), poor perceived economic status (HR = 0.653), working ≥40 h/week and high perceived physical workload (HR = 0.720) and higher job insecurity (HR = 0.825) negatively influenced time to RTW. For both men and women, probabilities of not returning to work varied widely according to workers' specific profile of personal and occupational factors (high or low risk profile). Results confirm the importance of gender-sensitive strategies to investigate RTW determinants from a gender perspective.

Chronic low-grade inflammation has been recognised as a key underlying mechanism for several chronic diseases, including cancer and CVD. Nutrition represents a host of key modifiable factors that influence chronic inflammation. Dietary inflammatory scores were developed to assess the inflammatory potential of the diet and have been associated with inflammatory biomarkers in cross-sectional and short-term longitudinal studies. The objective of this study was to investigate the relationship between the dietary inflammatory index (DII), the alternate dietary inflammatory index (ADII) and long-term C-reactive protein (CRP). We also tested age as an effect modifier of this relationship. Participants were selected in the Supplémentation en Vitamines et Minéraux Antioxydants study, which included subjects aged 45-60 years old for men and 35-60 years old for women in 1994. Participants with ≥3 24-h dietary records at baseline and a CRP measurement at the 12-year follow-up evaluation were included in the present study (n 1980). The relationships between the DII and ADII and elevated CRP (>3 mg/l) were investigated using logistic multivariable regression. All analyses were stratified by age (cut-off at median age=50 years old). The overall associations between DII and ADII and long-term CRP were not statistically significant (P trend across tertiles=0·16 for DII and 0·10 for ADII). A quantitative interaction was found between ADII score and age (P=0·16 for ADII, 0·36 for DII). In stratified analyses the ADII was significantly prospectively associated with CRP only in younger participants: OR tertile 3 v. tertile 1: 1·79 (95 % CI 1·04, 3·07). Pro-inflammatory diets may have long-term effect on CRP only in younger subjects.

Long-term increases in young-of-the-year growth of Arctic cisco Coregonus autumnalis and environmental influences

USGS Publications Warehouse

von Biela, Vanessa R.; Zimmerman, Christian E.; Moulton, L. L.

2011-01-01

Arctic cisco Coregonus autumnalis young-of-year (YOY) growth was used as a proxy to examine the long-term response of a high-latitude fish population to changing climate from 1978 to 2004. YOY growth increased over time (r2 = 0·29) and was correlated with monthly averages of the Arctic oscillation index, air temperature, east wind speed, sea-ice concentration and river discharge with and without time lags. Overall, the most prevalent correlates to YOY growth were sea-ice concentration lagged 1 year (significant correlations in 7 months; r2 = 0·14-0·31) and Mackenzie River discharge lagged 2 years (significant correlations in 8 months; r2 = 0·13-0·50). The results suggest that decreased sea-ice concentrations and increased river discharge fuel primary production and that life cycles of prey species linking increased primary production to fish growth are responsible for the time lag. Oceanographic studies also suggest that sea ice concentration and fluvial inputs from the Mackenzie River are key factors influencing productivity in the Beaufort Sea. Future research should assess the possible mechanism relating sea ice concentration and river discharge to productivity at upper trophic levels.

The length of gestation in Carthusian broodmares was calculated on the basis of 339 spontaneous full-term deliveries taking place in the 8-year period 1998-2005 from 158 broodmares and 29 stallions in a major farm of Spanish horses of Carthusian strain in southern Spain. Ultrasonography was used to determine follicular dehiscence, 1st day of pregnancy and to confirm conception in mares. Mean GL was 332.4 +/- 12.1 days, and a normal interval of 297-358 days was established for this breed. GL records were grouped on the basis of foal sex (colts or fillies), mating month (between November and January; February and April; May and July), age of the mare (4 to 7 years; 8 to 12 years; 13 to 17 years), breeding year, stallion and parity (primiparous vs. multiparous). GLs were 12.9 days shorter in mares mated between May and July than those mated between November and January and 15.3 days in mares mated between February and April (p < 0.001). Mares aged between 8-12 years had 5.3 days shorter GLs than those aged between 13-17 years (p < 0.05). Pregnancy was significantly 5.7 days longer when the mare gave birth to colts than fillies (p < 0.05). GL was 14.5 days longer in primiparous than in multiparous mares ( p < 0.001). No statistical differences in GL were found between the studied years. This study shows the influence of certain stallion on GL.

Psycho-neural Identity as the Basis for Empirical Research and Theorization in Psychology: An Interview with Mario A. Bunge

NASA Astrophysics Data System (ADS)

2012-10-01

Mario Bunge is one of the most prolific philosophers of our time. Over the past sixty years he has written extensively about semantics, ontology, epistemology, philosophy of science and ethics. Bunge has been interested in the philosophical and methodological implications of modern psychology and more specifically in the philosophies of the relation between the neural and psychological realms. According to Bunge, functionalism, the philosophical stand of current psychology, has limited explanatory power in that neural processes are not explicitly acknowledged as components or factors of psychological phenomena. In Matter and Mind (2010), Bunge has elaborated in great detail the philosophies of the mind-brain dilemma and the basis of the psychoneural identity hypothesis, which suggests that all psychological processes can be analysed in terms of neural and physical phenomena. This article is the result of a long interview with Dr. Bunge on psychoneural identity and brain-behaviour relations.

The aims of this Argentinian study were to describe and analyse the outcomes of a continuous interdisciplinary follow-up programme of patients with gastroschisis. This was a prospective, longitudinal study of babies with gastroschisis admitted from 1 November 2003 to 31 October 2014, and this paper presents results at one, three and six years of age. Matched-pairs analyses were carried out when they were one and six. We enrolled 62 babies and assessed 52 at one year of age, 34 at three years and 17 at six years. This showed that 63% had mental health problems and 5% had recurrent wheezing. Normal outcomes at one, three and six years were growth (80%, 85% and 80%), neurology-psychomotor development index (64%, 50% and 82%), audiology (100%, 76% and 76%), vision (98%, 94% and 89%) and language (55%, 62% and 65%). The rehospitalisation rates were 30%, 0.3% and zero, and the surgical re-intervention rates were 9%, 0.3% and 12%. Matched-pairs analysis showed no significant differences between outcomes at the ages of one and six. Babies born with gastroschisis were at risk for long-term morbidity and impairments, according to follow-up assessments at the ages of one, three and six years. ©2016 Foundation Acta Paediatrica.

Gut-directed hypnotherapy is considered to be an effective treatment in irritable bowel syndrome (IBS) but few studies report the long-term effects. This retrospective study aims to evaluate the long-term perceived efficacy of gut-directed hypnotherapy given outside highly specialized hypnotherapy centers. 208 patients, who all had received gut-directed hypnotherapy, were retrospectively evaluated. The Subjective Assessment Questionnaire (SAQ) was used to measure changes in IBS symptoms, and patients were classified as responders and non-responders. Patients were also asked to report changes in health-care seeking, use of drugs for IBS symptoms, use of alternative non-pharmacological treatments, and if they still actively used hypnotherapy. Immediately after hypnotherapy, 103 of 208 patients (49%) were responders and 75 of these (73%) had improved further at the follow-up 2-7 years after hypnotherapy (mean 4 years). A majority of the responders still used hypnotherapy on a regular basis at follow-up (73%), and the responders reported a greater reduction in health-care seeking than non-responders. A total of 87% of all patients reported that they considered gut-directed hypnotherapy to be worthwhile, and this differed between responders and non-responders (100% vs. 74%; p < 0.0001). This long-term follow-up study indicates that gut-directed hypnotherapy in refractory IBS is an effective treatment option with long-lasting effects, also when given outside highly specialized hypnotherapy centers. Apart from the clinical benefits, the reduction in health-care utilization has the potential to reduce the health-care costs.

Reducing Production Basis Risk through Rainfall Intensity Frequency (RIF) Indexes: Global Sensitivity Analysis' Implication on Policy Design

NASA Astrophysics Data System (ADS)

Muneepeerakul, Chitsomanus; Huffaker, Ray; Munoz-Carpena, Rafael

2016-04-01

The weather index insurance promises financial resilience to farmers struck by harsh weather conditions with swift compensation at affordable premium thanks to its minimal adverse selection and moral hazard. Despite these advantages, the very nature of indexing causes the presence of "production basis risk" that the selected weather indexes and their thresholds do not correspond to actual damages. To reduce basis risk without additional data collection cost, we propose the use of rain intensity and frequency as indexes as it could offer better protection at the lower premium by avoiding basis risk-strike trade-off inherent in the total rainfall index. We present empirical evidences and modeling results that even under the similar cumulative rainfall and temperature environment, yield can significantly differ especially for drought sensitive crops. We further show that deriving the trigger level and payoff function from regression between historical yield and total rainfall data may pose significant basis risk owing to their non-unique relationship in the insured range of rainfall. Lastly, we discuss the design of index insurance in terms of contract specifications based on the results from global sensitivity analysis.

Term Cancellations in Computing Floating-Point Gröbner Bases

Sasaki, Tateaki; Kako, Fujio

We discuss the term cancellation which makes the floating-point Gröbner basis computation unstable, and show that error accumulation is never negligible in our previous method. Then, we present a new method, which removes accumulated errors as far as possible by reducing matrices constructed from coefficient vectors by the Gaussian elimination. The method manifests amounts of term cancellations caused by the existence of approximate linearly dependent relations among input polynomials.

Evaluation of an 18-year CMAQ simulation: Seasonal variations and long-term temporal changes in sulfate and nitrate

This paper compares spatial and seasonal variations and temporal trends in modeled and measured concentrations of sulfur and nitrogen compounds in wet and dry deposition over an 18-year period (1988-2005) over a portion of the northeastern United States. Substantial emissions reduction programs occurred over this time period, including Title IV of the Clean Air Act Amendments of 1990 which primarily resulted in large decreases in sulfur dioxide (SO 2) emissions by 1995, and nitrogen oxide (NO x) trading programs which resulted in large decreases in warm season NO x emissions by 2004. Additionally, NO x emissions from mobile sources declined more gradually over this period. The results presented here illustrate the use of both operational and dynamic model evaluation and suggest that the modeling system largely captures the seasonal and long-term changes in sulfur compounds. The modeling system generally captures the long-term trends in nitrogen compounds, but does not reproduce the average seasonal variation or spatial patterns in nitrate.

Long-term use of cellular phones and brain tumours: increased risk associated with use for > or =10 years.

To evaluate brain tumour risk among long-term users of cellular telephones. Two cohort studies and 16 case-control studies on this topic were identified. Data were scrutinised for use of mobile phone for > or =10 years and ipsilateral exposure if presented. The cohort study was of limited value due to methodological shortcomings in the study. Of the 16 case-control studies, 11 gave results for > or =10 years' use or latency period. Most of these results were based on low numbers. An association with acoustic neuroma was found in four studies in the group with at least 10 years' use of a mobile phone. No risk was found in one study, but the tumour size was significantly larger among users. Six studies gave results for malignant brain tumours in that latency group. All gave increased odd ratios (OR), especially for ipsilateral exposure. In a meta-analysis, ipsilateral cell phone use for acoustic neuroma was OR = 2.4 (95% CI 1.1 to 5.3) and OR = 2.0, (1.2 to 3.4) for glioma using a tumour latency period of > or =10 years. Results from present studies on use of mobile phones for > or =10 years give a consistent pattern of increased risk for acoustic neuroma and glioma. The risk is highest for ipsilateral exposure.

Rainfall Intensity and Frequency Explain Production Basis Risk in Cumulative Rain Index Insurance

2017-12-01

With minimal moral hazard and adverse selection, weather index insurance promises financial resilience to farmers struck by harsh weather conditions through swift compensation at affordable premium. Despite these advantages, the very nature of indexing gives rise to production basis risk as the selected weather indexes do not sufficiently correspond to actual damages. To address this problem, we develop a stochastic yield model, built upon a stochastic soil moisture model driven by marked Poisson rainfall. Our analysis shows that even under similar temperature and rainfall amount yields can differ significantly; this was empirically supported by a 2-year field experiment in which rain-fed maize was grown under very similar total rainfall. Here, the year with more intense, less-frequent rainfall produces a better yield—a rare counter evidence to most climate change projections. Through a stochastic yield model, we demonstrate the crucial roles of rainfall intensity and frequency in determining the yield. Importantly, the model allows us to compute rainfall pattern-related basis risk inherent in cumulative rain index insurance. The model results and a case study herein clearly show that total rainfall is a poor indicator of yield, imposing unnecessary production basis risk on farmers and false-positive payouts on insurers. Incorporating rainfall intensity and frequency in the design of rain index insurance can offer farmers better protection, while maintaining the attractive features of the weather index insurance and thus fulfilling its promise of financial resilience.

Scoliotic curves do not necessarily stop progressing at skeletal maturity. The factors that influence curve behavior following bracing are not fully determined. Our objectives were to evaluate the loss of the scoliotic curve correction in a cohort of patients treated with bracing during adolescence and to compare the outcomes of 18 versus 23 h of bracing at a mean of 25 years post brace removal. Seventy-seven patients, who were successfully treated for Adolescent Idiopathic Scoliosis with Βoston brace, were re-evaluated 25 years after the end of their treatment. Patients were further divided in 2 matched groups; those wearing the brace for 23 h and those not wearing the brace at school-time, limiting the application of the brace to 18 h. The mean scoliotic curve was compared between groups before, during, just after bracing and 25 years post bracing. Validated in patients' native language forms of Short Form 36 and Oswestry Disability Index questionnaires were used to compare the quality of life between groups 25 years post bracing. The mean age of the cohort was 40.4 (±3.2) years. They underwent long term follow up at a mean of 25.16 (±2.69) years after brace removal. The mean cohort scoliotic curve increased by 3.9 (±6.69) at 25 years since brace removal. There was however no significant difference in the mean Cobb angle of the cohort between pre brace and long term follow up period (p = 0.307). The 18 and 23 h application groups were comparable according to demographics and several bracing and scoliotic curve parameters. There was no significant difference in the mean curve magnitude between 18 and 23 h application groups at brace removal (p = 0.512) and at 25 years follow-up (p = 0.878). There was also no significant difference in the mean score of Quality of Life questionnaires between groups at long term follow up. Scoliotic curves do not necessarily stop progressing after bracing.
