    Full Text Available Background: Physical exercise is a strategy to control hypertension and attenuate pressure overload-induced cardiac remodeling. The influence of exercise on cardiac remodeling during uncontrolled hypertension is not established. We evaluated the effects of a long-term low intensity aerobic exercise protocol on heart failure (HF development and cardiac remodeling in aging spontaneously hypertensive rats (SHR. Methods: Sixteen month old SHR (n=50 and normotensive Wistar-Kyoto (WKY, n=35 rats were divided into sedentary (SED and exercised (EX groups. Rats exercised in treadmill at 12 m/min, 30 min/day, 5 days/week, for four months. The frequency of HF features was evaluated at euthanasia. Statistical analyses: ANOVA and Tukey or Mann-Whitney, and Goodman test. Results: Despite slightly higher systolic blood pressure, SHR-EX had better functional capacity and lower HF frequency than SHR-SED. Echocardiography and tissue Doppler imaging showed no differences between SHR groups. In SHR-EX, however, left ventricular (LV systolic diameter, larger in SHR-SED than WKY-SED, and endocardial fractional shortening, lower in SHR-SED than WKY-SED, had values between those in WKY-EX and SHR-SED not differing from either group. Myocardial function, assessed in LV papillary muscles, showed improvement in SHR-EX over SHR-SED and WKY-EX. LV myocardial collagen fraction and type I and III collagen gene expression were increased in SHR groups. Myocardial hydroxyproline concentration was lower in SHR-EX than SHR-SED. Lysyl oxidase gene expression was higher in SHR-SED than WKY-SED. Conclusion: Exercise improves functional capacity and reduces decompensated HF in aging SHR independent of elevated arterial pressure. Improvement in functional status is combined with attenuation of LV and myocardial dysfunction and fibrosis.

    Due to large and increasing numbers of cancer survivors, long-term cancer-related health issues have become a major focus of attention. This study examined the relation between a high-intensity physical rehabilitation program and return-to-work in cancer survivors who had received chemotherapy. The intervention group, consisting of 72 cancer survivors from one hospital (8 men and 64 women, mean age 49 years), followed an 18-weeks rehabilitation program including strength and interval training, and home-based activities. An age-matched control group, consisting of 38 cancer survivors (9 men and 29 women), was recruited from two other hospitals. They received only standard medical care. All subjects were evaluated during a telephone interview on employment issues, conducted at ±3 years after diagnosis. The main outcomes were change in working hours per week and time until return-to-work. Patients in the intervention group showed significant less reduction in working hours per week [-5.0 h/week vs. -10.8 h/week (P = .03)]. Multivariate analyses showed that the training intervention, the age of patients, and the number of working hours pre-diagnosis could explain the improvement in long-term participation at work. Time until (partial) return-to-work was 11.5 weeks for the intervention group versus 13.2 weeks for the control group (P = .40). On long-term follow-up, 78% of the participants from the intervention group versus 66% from the control group had returned to work on the pre-diagnosis level of working hours (P = .18). Rehabilitation using high-intensity physical training is useful for working patients to minimize the decreased ability to work resulting from cancer and its treatment.

    The present study examined the neural correlates of long-term intense romantic love using functional magnetic resonance imaging (fMRI). Ten women and 7 men married an average of 21.4 years underwent fMRI while viewing facial images of their partner. Control images included a highly familiar acquaintance; a close, long-term friend; and a low-familiar person. Effects specific to the intensely loved, long-term partner were found in: (i) areas of the dopamine-rich reward and basal ganglia system, such as the ventral tegmental area (VTA) and dorsal striatum, consistent with results from early-stage romantic love studies; and (ii) several regions implicated in maternal attachment, such as the globus pallidus (GP), substantia nigra, Raphe nucleus, thalamus, insular cortex, anterior cingulate and posterior cingulate. Correlations of neural activity in regions of interest with widely used questionnaires showed: (i) VTA and caudate responses correlated with romantic love scores and inclusion of other in the self; (ii) GP responses correlated with friendship-based love scores; (iii) hypothalamus and posterior hippocampus responses correlated with sexual frequency; and (iv) caudate, septum/fornix, posterior cingulate and posterior hippocampus responses correlated with obsession. Overall, results suggest that for some individuals the reward-value associated with a long-term partner may be sustained, similar to new love, but also involves brain systems implicated in attachment and pair-bonding.

    Energy intensity of the economy is often modeled as being determined by the combined effect of a fixed price elasticity of demand, and an exogenously specified, fixed technical change parameter denoted as the autonomous energy efficiency improvement (AEEI). Typically, the AEEI rate is set to 0.5-1.5% improvement per annum. Here, we study historic aggregate energy intensity trends for the US from 1954 to 1994. We show that the historic trends are inconsistent with an autonomous model of improved energy efficiency-especially when the model is used to inform policies that impact energy prices. As an alternative we propose a model of price-induced efficiency, π, in which aggregate energy intensity trends respond to changes in energy prices beyond price elasticity of demand ε. Our exercise reveals that the aggregate price elasticity of energy demand of the US economy has declined by roughly 15% over the past four decades. But beyond this decline, bringing our simulations and historical data into close correspondence requires π to change sign before and after 1974. Before 1974, after accounting for price elasticity of demand, the economy was growing less energy efficient. After 1974, after accounting for the price elasticity of demand, the economy was growing more energy efficient. Furthermore, since 1984, the rate of energy efficiency gain has been declining. When projections of long-term energy use are compared, those with a price-induced energy efficiency formulation generate significantly more price sensitive energy use and emissions trajectories. When in the business as usual scenario energy prices are expected to be rising, climate policies involve lower shadow carbon prices with π than with AEEI formulations. In scenarios where energy prices are relatively flat, energy intensity rises leading to CO 2 emissions far higher than standard business as usual projections utilizing AEEI assumptions

  9. Reconstructing the long-term cosmic ray intensity: linear relations do not work

    Full Text Available It was recently suggested (Lockwood, 2001 that the cosmic ray intensity in the neutron monitor energy range is linearly related to the coronal source flux, and can be reconstructed for the last 130 years using the long-term coronal flux estimated earlier. Moreover, Lockwood (2001 reconstructed the coronal flux for the last 500 years using a similar linear relation between the flux and the concentration of cosmogenic 10 Be isotopes in polar ice. Here we show that the applied linear relations are oversimplified and lead to unphysical results on long time scales. In particular, the cosmic ray intensity reconstructed by Lockwood (2001 for the last 130 years has a steep trend which is considerably larger than the trend estimated from observations during the last 65 years. Accordingly, the reconstructed cosmic ray intensity reaches or even exceeds the local interstellar cosmic ray flux around 1900. We argue that these unphysical results obtained when using linear relations are due to the oversimplified approach which does not take into account the complex and essentially nonlinear nature of long-term cosmic ray modulation in the heliosphere. We also compare the long-term cosmic ray intensity based on a linear treatment with the reconstruction based on a recent physical model which predicts a considerably lower cosmic ray intensity around 1900.Key words.

    At the present time we know only one possibility to reconstruct the Cosmic Ray intensity in the past. This possibility is connected with the measurements of radiocarbon abundance in the dendrochronologically dated wood samples. As the experiments carried out with the help of spacecrafts, balloons and ground apparatus show the Galactic Cosmic Ray flux essentially varies on a short time scales. The variations are caused by different astrophysical and geophysical phenomena. 14 C isotope allows us to investigate these reasons on a more long time interval in comparison with direct observational possibilities

    Sexuality and sexual needs in older adults remains a neglected area of clinical intervention, particularly so in long-term care settings. Because older adults in medical rehabilitation and long-term care beds present with significant frailties, and often significant neurocognitive disorders, it makes it difficult for occupational therapists and other staff to evaluate the capacity of an older adult resident to participate in sexual relationships. The current paper reviews the current literature on sexuality and aging, examines some of the clinical practices and guidelines regarding sexual expression in long-term care, and presents two case examples. A semistructured interview and decision tree is presented to assist therapists in making careful and informed decisions and thereby balancing the needs for protection with the needs for autonomy.

    Moderate exercise promotes learning and memory. Most studies mainly focused on memory exercise effects of in the ageing and patients. There is lack of quantitative research about effect of regular exercise intensity on different memory types in normal subjects. Present study investigated the effects of different intensities of treadmill exercise on working memory and long-term memory. Fifty female Wistar rats were trained by T-maze delayed spatial alternation (DSA) task with 3 delays (10s, 60s and 300s). Then they got a 30min treadmill exercise for 30days in 4 intensities (control, 0m/min; lower, 15m/min; middle, 20m/min, and higher, 30m/min). Then animals were tested in DSA, passive avoidance and Morris water maze tasks. 1. Exercise increased the neuronal density of hippocampal subregions (CA1, CA3 and dentate gyrus) vs. naïve/control. 2. In DSA task, all groups have similar baseline, lower intensity improved 10s delay accuracy vs. baseline/control; middle and higher intensities improved 300s delay accuracy vs. baseline/control. 3. In water maze learning, all groups successfully found the platform, but middle intensity improved platform field crossing times vs. control in test phase. Present results suggested that treadmill exercise can improve long-term spatial memory and working memory; lower intensity benefits to short-term delayed working memory, and middle or higher intensity benefits to long-term delayed working memory. There was an inverted U dose-effect relationship between exercise intensity and memory performance, but exercise -working memory effect was impacted by delay duration. Copyright © 2016 Elsevier Inc.

    Cross-sectional. To describe participation in leisure time physical activity (LTPA) (amount, intensity and type) among older adults with long-term spinal cord injury (SCI), and to investigate the associations with sociodemographics, injury characteristics and secondary health conditions (SHCs). Home settings in southern Sweden. Data from the Swedish Aging with Spinal Cord Injury Study (SASCIS). The physical activity recall assessment for people with SCI was used to assess LTPA among 84 men and 35 women (mean age 63.5 years, mean time since injury 24 years, injury levels C1-L5, American Spinal Injury Association Impairment Scale A-D). Associations were analyzed statistically using hierarchical multivariable regression. Twenty-nine percent reported no LTPA, whereas 53% performed moderate-to-heavy intensity LTPA. The mean minutes per day of total LTPA was 34.7 (±41.5, median 15, range 0-171.7) and of moderate-to-heavy LTPA 22.5 (±35.1, median 5.0, range 0-140.0). The most frequently performed activities were walking and wheeling. Sociodemographics, injury characteristics and SHCs (bowel-related and bladder-related problems, spasticity and pain) explained 10.6% and 13.4%, respectively, of the variance in total and moderate-to-heavy LTPA. Age and wheelchair use were significantly, negatively associated with total LTPA. Women, wheelchair users and employed participants performed significantly less moderate-to-heavy LTPA than men, those using walking devices/no mobility device and unemployed participants. Many older adults with long-term SCI do not reach the amount or intensity of LTPA needed to achieve fitness benefits. Research is needed on how to increase LTPA and to identify modifiable factors that could enhance their participation.

    The long-term continuous cropping experiment at IRRI is cultivated with three rice crops in a year, making it the world's most intensively cropped long-term rice experiment. The availability of comprehensive rice production records, compiled weather data, and tested crop models provides a means to evaluate long-term trends in measured and potential yields and yield gaps in this rice production system. Yield trends were assessed using the highest yielding cultivar in each cropping season from 1979 to 2005. Potential yield of the highest yielding cultivar in each season was determined using three rice models (ORYZA, TERM, and CERES) run with the actual transplanting and harvest dates for the cultivar. The yield gap was determined from the difference between the simulated potential grain yield and the measured grain yield. Measured and potential yields and the yield gap varied across seasons and years. Measured yields were higher in the dry season than in the early and late wet seasons. The yield gap tended to be higher in the wet season than in the dry season. Climatic parameters, particularly solar radiation, influenced the performance of rice cultivars. The relatively larger yield gaps in the late wet season than in the dry season were associated with increased spikelet sterility. The cumulative measured yield for the three annual rice crop was near 80 percent of the annual yield potential in years with best practices for fertilizer N and crop management. The long term trends suggest that effective timing and rates of N fertilization and effective control of diseases were critical in achieving 80 percent of the annual yield potential

    The aim of this study was to explore the relationship between leisure-time physical inactivity and long-term sickness absence in a representative sample of individuals aged 16-54 years, within the labour market and in good health. It was hypothesised that physically inactive individuals have a higher risk of long-term sickness absence and longer duration of sickness absence. The study population was identified from the National Health and Morbidity Survey, 2010. Weekly data on long-term sickness absence were obtained from the National Register on Social Transfer Payments (the DREAM registry). The association of incidence and duration of long-term sickness absence with physical inactivity was explored using logistic and Poisson regression. Data were fitted to models with levels of physical activity, demographic, social and lifestyle characteristics as independent variables. A combined hurdle model was used to estimate the difference in mean number of absence weeks. Logistic regression showed that physically inactive individuals had a 27% higher incidence of long-term sickness absence compared with physically active individuals. The Poisson regression showed that long-term sickness absence was only slightly shorter (1 week less) for moderately active individuals compared with inactive individuals. The hurdle model estimated longer absence periods for inactive individuals (additional 2.5 weeks) in comparison with moderately and highly active individuals. The study showed that physically inactive individuals have a higher incidence of long-term absence and that physically inactive individuals have longer periods with sickness absence than moderately and highly active individuals. When adjustments for social and health behaviour were included, the estimated associations became statistically insignificant.

    Full Text Available Abstract Background Reduced vocal intensity is a core impairment of hypokinetic dysarthria in Parkinson’s disease (PD. Speech treatments have been developed to rehabilitate the vocal subsystems underlying this impairment. Intensive treatment programs requiring high-intensity voice and speech exercises with clinician-guided prompting and feedback have been established as effective for improving vocal function. Less is known, however, regarding long-term outcomes of clinical benefit in speakers with PD who receive these treatments. Methods A retrospective cohort design was utilized. Data from 78 patient files across a three year period were analyzed. All patients received a structured, intensive program of voice therapy focusing on speaking intent and loudness. The dependent variable for all analyses was vocal intensity in decibels (dBSPL. Vocal intensity during sustained vowel production, reading, and novel conversational speech was compared at pre-treatment, post-treatment, six month follow-up, and twelve month follow-up periods. Results Statistically significant increases in vocal intensity were found at post-treatment, 6 months, and 12 month follow-up periods with intensity gains ranging from 5 to 17 dB depending on speaking condition and measurement period. Significant treatment effects were found in all three speaking conditions. Effect sizes for all outcome measures were large, suggesting a strong degree of practical significance. Conclusions Significant increases in vocal intensity measured at 6 and 12 moth follow-up periods suggested that the sample of patients maintained treatment benefit for up to a year. These findings are supported by outcome studies reporting treatment outcomes within a few months post-treatment, in addition to prior studies that have reported long-term outcome results. The positive treatment outcomes experienced by the PD cohort in this study are consistent with treatment responses subsequent to other treatment

    A 20-year-old male patient was admitted in our department 14 h after paraquat poisoning at the dose of about 50 mL. The patient underwent intensive hemoperfusion for 2 h (3 times a day) for 9 consecutive days and received continuous renal replacement therapy (CRRT) in the mode of continuous veno-venous hemofiltration (CVVH) for 10 consecutive days in addition to routine medications. The biochemical indexes were monitored during the therapy. After the treatment, paraquat concentrations in the blood and urine were decreased, and the patient's urine volume (UV) increased, serum creatinine (Cr) level decreased, and the oxygenation index became normal. Dynamic CT scan showed no obvious pulmonary fibrosis. The patient was followed up for 6 months after discharge and no complaint of discomforts was reported. This case suggests that early intensive hemoperfusion and long-term CVVH may help improve the prognosis after paraquat poisoning.

    Despite positive associations between chronic physical activity and memory; we have little understanding of how best to incorporate physical activity during the day to facilitate the consolidation of information into memory, nor even how time spent physically active during the day relates to memory processes. The purpose of this investigation was to examine the relation between physical activity during the day and long-term memory. Ninety-two young adults learned a list of paired-associate items and were tested on the items after a 12-hour interval during which heart rate was recorded continuously. Although the percentage of time spent active during the day was unrelated to memory, two critical physical activity periods were identified as relating to the maintenance of long-term memory. Engaging in physical activity during the period 1 to 2-hours following the encoding of information was observed to be detrimental to the maintenance of information in long-term memory. In contrast, physical activity during the period 1-hour prior to memory retrieval was associated with superior memory performance, likely due to enhanced retrieval processing. These findings provide initial evidence to suggest that long-term memory may be enhanced by more carefully attending to the relative timing of physical activity incorporated during the day.

    Cannabis intoxication adversely affects health, yet persistent effects following short-term abstinence in long-term cannabis users are unclear. This matched-subjects, cross-sectional study compared health outcomes of long-term cannabis and long-term tobacco-only users, relative to population norms. Nineteen long-term (mean 32.3years of use, mean age 55.7years), abstinent (mean 15h) cannabis users and 16 long-term tobacco users (mean 37.1years of use, mean age 52.9years), matched for age, educational attainment, and lifetime tobacco consumption, were compared on measures of learning and memory, response inhibition, information-processing, sustained attention, executive control, and mental and physical health. Cannabis users exhibited poorer overall learning and delayed recall and greater interference and forgetting than tobacco users, and exhibited poorer recall than norms. Inhibition and executive control were similar between groups, but cannabis users had slower reaction times during information processing and sustained attention tasks. Cannabis users had superior health satisfaction and psychological, somatic, and general health than tobacco users and had similar mental and physical health to norms whilst tobacco users had greater stress, role limitations from emotional problems, and poorer health satisfaction. Long-term cannabis users may exhibit deficits in some cognitive domains despite short-term abstinence and may therefore benefit from interventions to improve cognitive performance. Tobacco alone may contribute to adverse mental and physical health outcomes, which requires appropriate control in future studies. Copyright © 2017 Elsevier Ltd. All rights reserved.

    We report the detection of changes in the long-term intensity variations in two X-ray binaries, Cyg X-2 and LMC X-3. In this work, we have used the long-term light curves obtained with the All-Sky Monitors (ASMs) of the Rossi X-Ray Timing Explorer (RXTE), Ginga, Ariel 5, and Vela 5B and the scanning modulation collimator of HEAO 1. It is found that in the light curves of both the sources, obtained with these instruments at various times over the last 30 years, more than one periodic or quasi-periodic component is always present. The multiple prominent peaks in the periodograms have frequencies unrelated to each other. In Cyg X-2, RXTE-ASM data show strong peaks at 40.4 and 68.8 days, and Ginga-ASM data show strong peaks at 53.7 and 61.3 days. Multiple peaks are also observed in LMC X-3. The various strong peaks in the periodograms of LMC X-3 appear at 104, 169, and 216 days (observed with RXTE-ASM) and 105, 214, and 328 days (observed with Ginga-ASM). The present results, when compared with the earlier observations of periodicities in these two systems, demonstrate the absence of any stable long period. The 78 day periodicity detected earlier in Cyg X-2 was probably due to the short time base in the RXTE data that were used, and the periodicity of 198 days in LMC X-3 was due to a relatively short duration of observation with HEAO 1.

    2010-01-01

    Purpose: To investigate long-term swallowing function in oropharyngeal cancer patients treated with intensity-modulated radiotherapy (IMRT), and to identify novel dose-limiting criteria predictive for dysphagia. Methods and Materials: Thirty-one patients with Stage IV oropharyngeal squamous carcinoma enrolled on a Phase II trial were prospectively evaluated by modified barium swallow studies at baseline, and 6, 12, and 24 months post-IMRT treatment. Candidate dysphagia-associated organs at risk were retrospectively contoured into original treatment plans. Twenty-one (68%) cases were base of tongue and 10 (32%) were tonsil. Stage distribution was T1 (12 patients), T2 (10), T3 (4), T4 (2), and TX (3), and N2 (24), N3 (5), and NX (2). Median age was 52.8 years (range, 42-78 years). Thirteen patients (42%) received concurrent chemotherapy during IMRT. Thirteen (42%) were former smokers. Mean dose to glottic larynx for the cohort was limited to 18 Gy (range, 6-39 Gy) by matching IMRT to conventional low-neck fields. Results: Dose-volume constraints (V30 < 65% and V35 < 35% for anterior oral cavity and V55 < 80% and V65 < 30% for high superior pharyngeal constrictors) predictive for objective swallowing dysfunction were identified by univariate and multivariate analyses. Aspiration and feeding tube dependence were observed in only 1 patient at 24 months. Conclusions: In the context of glottic laryngeal shielding, we describe candidate oral cavity and superior pharyngeal constrictor organs at risk and dose-volume constraints associated with preserved long-term swallowing function; these constraints are currently undergoing prospective validation. Strict protection of the glottic larynx via beam-split IMRT techniques promises to make chronic aspiration an uncommon outcome.

    Understanding the spatiotemporal change trend of global crop growth and multiple cropping system under climate change scenarios is a critical requirement for supporting the food security issue that maintains the function of human society. Many studies have predicted the effects of climate changes on crop production using a combination of filed studies and models, but there has been limited evidence relating decadal-scale climate change to global crop growth and the spatiotemporal distribution of multiple cropping system. Using long-term satellite-derived Normalized Difference Vegetation Index (NDVI) and observed climate data from 1982 to 2012, we investigated the crop growth trend, spatiotemporal pattern trend of agricultural cropping intensity, and their potential correlations with respect to the climate change drivers at a global scale. Results show that 82.97 % of global cropland maximum NDVI witnesses an increased trend while 17.03 % of that shows a decreased trend over the past three decades. The spatial distribution of multiple cropping system is observed to expand from lower latitude to higher latitude, and the increased cropping intensity is also witnessed globally. In terms of regional major crop zones, results show that all nine selected zones have an obvious upward trend of crop maximum NDVI (p impact on the crop growth trend.

    The impact of long-term training on systemic and mucosal immunity was assessed prospectively in a cohort of elite swimmers over a 7-month training season in preparation for national championships. The results indicated significant suppression (P training at an intensive level. There was also a trend towards lower IgG2 subclass levels in serum in athletes compared with controls (P = 0.07). There were no significant changes in numbers or percentages of B or T cell subsets, but there was a significant fall in natural killer (NK) cell numbers and percentages in athletes over the training season (P training sessions there was a significant decrease in salivary IgA levels for athletes compared with controls (P = 0.002). In athletes there was a downward trend in salivary IgA levels over the 7-month training period in both the pre-exercise (P = 0.06) and post-exercise samples (P = 0.04). There were no significant trends in salivary IgG levels over the study period in either athletes or controls. The only significant change in salivary IgM levels was an increase in detection rate in the pre-competition phase in athletes (P = 0.03). The study suggests that training of elite athletes at an intensive level over both short- and long-time frames suppresses both systemic and mucosal immunity. Protracted immune suppression linked with prolonged training may determine susceptibility to infection, particularly at times of major competitions.

    2010-02-01

    To report the long-term outcome of deceased donor kidney transplantation in children with emphasis on the use of an intensive initial immunosuppression protocol using R-ATG as antibody induction. Between January 1991 and December 1997, 82 deceased donor kidney transplantations were performed in 75 pediatric recipients. Mean recipient age at transplantation was 12.9 yr and the mean follow-up period was 12.6 yr. All patients received quadruple immunosuppression with steroid, cyclosporine, azathioprine, and antibody induction using R-ATG-Fresenius. Actual one, five, and 10 yr patient survival rates were 99%, 97%, and 94%, respectively; only one patient (1.2%) developed PTLD. Actual one, five, and 10 yr overall graft survival rates were 84%, 71%, and 50%, respectively; there were five cases (6%) of graft thrombosis and the actual immunological graft survival rates were 91%, 78%, and 63% at one, five, and 10 yr, respectively. The use of an intensive initial immunosuppression protocol with R-ATG as antibody induction is safe and effective in pediatric recipients of deceased donor kidneys with excellent immunological graft survival without an increase in PTLD or other neoplasms over a minimum 10-yr follow up.

    2012-12-01

    The central purpose of pulmonary rehabilitation is to reduce morbidity by improving functional capacity through exercise. It is still unknown if improvements in functional capacity are maintained in the long-term and if this leads to increased physical activity levels as measured by a free-living activity monitor. The hypothesis of this study was that pulmonary rehabilitation would lead to a sustained increase in standard outcome measures and in daily physical activity.

    To assess aspirations for physical health over 18 months. To examine whether maintained importance of aspirations for physical health mediated and/or moderated the effect of an intensive intervention on long-term tobacco abstinence. Participants were randomly assigned to an intervention based on self-determination theory or to community care, and provided data at baseline and at 18 and 30 months post-randomization. Aspirations for physical health were better maintained over 18 months among participants in the intervention (mean change=.05), relative to community care (mean change=-.13), t=2.66, p<.01. Maintained importance of aspirations for physical health partially mediated the treatment condition effects on seven-day point prevalence tobacco abstinence (z'=1.68, p<.01) and the longest number of days not smoking (z'=2.16, p<.01), and interacted with treatment condition to facilitate the longest number of days not smoking (beta=.08, p<.05). Maintained importance of aspirations for physical health facilitated tobacco abstinence. Smokers may benefit from discussing aspirations for physical health within autonomy-supportive interventions. Patients may benefit from discussing aspirations during counseling about therapeutic lifestyle change and medication use.

  18. Threshold of musculoskeletal pain intensity for increased risk of long-term sickness absence among female healthcare workers in eldercare.

    Directory of Open Access Journals (Sweden)

    Lars L Andersen

    Full Text Available PURPOSE: Musculoskeletal disorders increase the risk for absenteeism and work disability. However, the threshold when musculoskeletal pain intensity significantly increases the risk of sickness absence among different occupations is unknown. This study estimates the risk for long-term sickness absence (LTSA from different pain intensities in the low back, neck/shoulder and knees among female healthcare workers in eldercare. METHODS: Prospective cohort study among 8,732 Danish female healthcare workers responding to a questionnaire in 2004-2005, and subsequently followed for one year in a national register of social transfer payments (DREAM. Using Cox regression hazard ratio (HR analysis we modeled risk estimates of pain intensities on a scale from 0-9 (reference 0, where 0 is no pain and 9 is worst imaginable pain in the low back, neck/shoulders and knees during the last three months for onset of LTSA (receiving sickness absence compensation for at least eight consecutive weeks during one-year follow-up. RESULTS: During follow-up, the 12-month prevalence of LTSA was 6.3%. With adjustment for age, BMI, smoking and leisure physical activity, the thresholds of pain intensities significantly increasing risk of LTSA for the low back (HR 1.44 [95%CI 1.07-1.93], neck/shoulders (HR 1.47 [95%CI 1.10-1.96] and knees (HR 1.43 [95%CI 1.06-1.93] were 5, 4 and 3 (scale 0-9, respectively, referencing pain intensity of 0. CONCLUSION: The threshold of pain intensity significantly increasing the risk for LTSA among female healthcare workers varies across body regions, with knee pain having the lowest threshold. This knowledge may be used in the prevention of LTSA among health care workers.

    Full Text Available Previous studies have shown that athletic training or other physical activity causes structural and functional adaptations in the heart, but less is known how long-term physical activity affects heart when genetic liability and childhood environment are taken into account. The aim of this study was to investigate the effects of long-term physical activity vs. inactivity on cardiac structure and function in twin pairs discordant for physical activity for 32 years. Twelve same-sex twin pairs (five monozygotic and seven dizygotic, 50-67 years were studied as a part of the TWINACTIVE study. Discordance in physical activity was initially determined in 1975 and it remained significant throughout the follow-up. At the end of the follow-up in 2007, resting echocardiographic and electrocardiographic measurements were performed. During the follow-up period, the active co-twins were on average 8.2 (SD 4.0 MET hours/day more active than their inactive co-twins (p < 0.001. At the end of the follow-up, resting heart rate was lower in the active than inactive co-twins [59 (SD 5 vs. 68 (SD 10 bpm, p=0.03]. The heart rate-corrected QT interval was similar between the co-twins. Also, there was a tendency for left ventricular mass per body weight to be greater and T wave amplitude in lead II to be higher in the active co-twins (18% and 15%, respectively, p=0.08 for both. Similar trends were found for both monozygotic and dizygotic twin pairs. In conclusion, the main adaptation to long- term physical activity is lowered resting heart rate, even after partially or fully controlling for genetic liability and childhood environment

    OBJECTIVE: To evaluate prospectively the influence of habitual physical activity on body weight of men and women and to develop a model that defines the role of physical activity on longitudinal weight change. DESIGN AND SETTING: Occupational cohort study conducted for a mean of 5.5 y. SUBJECTS: A total of 496 (341 male and 155 female) NASA/Johnson Space Center employees who completed the 3 month education component of the employee health-related fitness program and remained involved for a minimum of 2 y. MEASUREMENTS: Body weights were measured at baseline (T1) and follow-up (T2), and habitual physical activity was obtained from the mean of multiple ratings of the 11-point (0-10) NASA Activity Scale (NAS) recorded quarterly between T1 and T2. Other measures included age, gender, VO(2 max) obtained from maximal treadmill testing, body mass index (BMI), and body fat percentage. RESULTS: Multiple regression demonstrated that mean NAS, T1 weight, aging and gender all influence long-term T2 weight. T1 age was significant for the men only. Independently, each increase in mean NAS significantly (Pmen (b=-0.91 kg; 95% CI:-1.4 to-0.42 kg) and women (b=-2.14 kg; 95% CI:-2.93 to-1.35 kg). Mean NAS had a greater effect on T2 weight as T1 weight increased, and the relationship was dose-dependent. CONCLUSIONS: Habitual physical activity is a significant source of long-term weight change. The use of self-reported activity level is helpful in predicting long-term weight changes and may be used by health care professionals when counseling patients about the value of physical activity for weight control.

    To examine the long-term effects of the Integrated Nutrition and Physical Activity Program (INPAP), a school-based nutrition education program. Quasi-experimental design comparing intervention and comparison cohorts at 3-6 years after delivery of the INPAP intervention on nutrition- and physical activity-related outcomes. This study was conducted in 1 school district in a low-income rural county of ∼15,000 residents in south-central Colorado. In second grade, intervention and comparison cohorts included 173 (fall 2000) and 190 (fall 1999) students, respectively. Approximately 60% of these students completed assessments in eighth grade. INPAP is an experiential school-based nutrition education program, grounded in social cognitive theory and Piaget's cognitive development theory and adapted for use in a rural setting. Nutrition and physical activity knowledge, self-efficacy, attitudes and behaviors, body mass index. Wilcoxon signed rank test, chi-square test for proportions, and t test for means. Long-term effects were observed in nutrition-related knowledge and attitudes but not self-efficacy or behavior change. The effects that did occur were attenuated over time. This study found that INPAP implemented in elementary school had limited lasting effects by the end of middle school, a time when students have increased autonomy to make food choices.

    Many men diagnosed with prostate cancer (PC) will experience physical and psychosocial late effects of treatment. Their interest/preferences for receiving information about addressing common sequelae is not well understood. We examined long-term PC survivors' level of interest, whether this differed based upon symptomatology, and their preferred coping information source. N=615 PC survivors (3-8 years post-diagnosis) completed a survey on physical and psychological health and their information interests and preferences related to late effects of cancer treatment. Over half of PC survivors reported interest in information about late effects of treatment or sexual health, while approximately a quarter were interested in emotional health information. Survivors preferred to receive information about late effects of treatment from their oncologists, sexual health information from their primary care providers (PCP), oncologist, or written/online resources, and emotional health information from their PCP. Information needs were more commonly reported among men with poorer domain-specific health functioning. Long-term PC survivors report significant interest in receiving information about their physical, sexual, and emotional health. Medical providers caring for these men should inquire about survivors' information needs and future intervention efforts should consider who delivers the information, dependent upon the type of dysfunction reported.

    A physically active lifestyle and a relatively high level of cardiorespiratory fitness are important for longevity and long-term health. No population-based study has prospectively assessed the association of physical activity levels with long-term peak oxygen uptake (VO(2peak)). 1843 individuals (906 women and 937 men) who were between 18 and 66 yr at baseline and were free from known lung or heart diseases at both baseline (1984-1986) and follow-up (2006-2008) were included in the study. Self-reported physical activity was recorded at both occasions, and VO(2peak) was measured at follow-up. The association of physical activity levels and VO(2peak) was adjusted for age, level of education, smoking status, and weight change from baseline to follow-up, using ANCOVA statistics. The level of physical activity at baseline was strongly associated with VO(2peak) at follow-up 23 yr later in both men and women (Ptrends active at baseline had higher (3.3 and 4.6 mL·kg(-1)·min(-1)) VO(2peak) at follow-up. Women who were inactive at baseline but highly active at follow-up had 3.7 mL·kg(-1)·min(-1) higher VO(2peak) compared with women who were inactive both at baseline and at follow-up. The corresponding comparison in men showed a difference of 5.2 mL·kg(-1)·min(-1) (95% confidence interval = 3.1-7.3) in VO(2peak). Physical activity level at baseline was positively associated with directly measured cardiorespiratory fitness (VO(2peak)) 23 yr later. People who changed from low to high activity during the observation period had substantially higher V˙O(2peak) at follow-up compared with people whose activity remained low.

  7. Natural physical and biological processes compromise the long-term performance of compacted soil caps

    Compacted soil barriers are components of essentially all caps placed on closed waste disposal sites. The intended functions of soil barriers in waste facility caps include restricting infiltration of water and release of gases and vapors, either independently or in combination with synthetic membrane barriers, and protecting other manmade or natural barrier components. Review of the performance of installed soil barriers and of natural processes affecting their performance indicates that compacted soil caps may function effectively for relatively short periods (years to decades), but natural physical and biological processes can be expected to cause them to fail in the long term (decades to centuries). This paper addresses natural physical and biological processes that compromise the performance of compacted soil caps and suggests measures that may reduce the adverse consequences of these natural failure mechanisms

    Effects of physical activity on bone properties, when controlled for genetic effects, are not fully understood. We aimed to study the association between long-term leisure time physical activity (LTPA) and bone properties using twin pairs known to be discordant for leisure time physical activity for at least 30 yr. Volumetric BMD and geometric properties were measured at the tibia shaft and distal end using pQCT in 16 middle-aged (50-74 yr) same-sex twin pairs (seven monozygotic [MZ] and nine dizygotic [DZ] pairs) selected from a population-based cohort. Paired differences between active and inactive co-twins were studied. Active members of MZ twin pairs had larger cortical bone cross-sectional area (intrapair difference: 8%, p = 0.006), thicker cortex (12%, p = 0.003), and greater moment of inertia (I(max), 20%, p = 0.024) at the tibia shaft than their inactive co-twins. At the distal tibia, trabecular BMD (12%, p = 0.050) and compressive strength index (18%, p = 0.038) were also higher in physically active MZ pair members than their inactive co-twins. The trends were similar, but less consistently so, in DZ pairs as in MZ pairs. Our genetically controlled study design shows that LTPA during adulthood strengthens bones in a site-specific manner, that is, the long bone shaft has a thicker cortex, and thus higher bending strength, whereas the distal bone has higher trabecular density and compressive strength. These results suggest that LTPA has a potential causal role in decreasing the long-term risk of osteoporosis and thus preventing osteoporotic fractures.

    Longer survival for children with sarcoma has led to the recognition of chronic health conditions related to prior therapy. We sought to study the association of sarcoma therapy with the development of scoliosis. We reviewed patient demographics, treatment exposures, and functional outcomes for patients surviving >10 years after treatment for sarcoma between 1964 and 2002 at our institution. The diagnosis of scoliosis was determined by imaging. Functional performance and standardized questionnaires were completed in a long-term follow-up clinic. We identified 367 patients, with median age at follow-up of 33.1 years. Scoliosis was identified in 100 (27.2%) patients. Chest radiation (relative risk (RR), 1.88 (95% confidence interval (CI), 1.21-2.92), p sarcoma are at risk of developing scoliosis when treatment regimens include chest radiation or rib resection. Identification of these risk factors may allow for early intervention designed to prevent adverse long-term outcomes. Cancer survivors at risk of developing scoliosis may benefit from monitoring of pulmonary status and early physical therapy.

    In the southwestern US, the summertime North American Monsoon (NAM) provides about 60% of the region's annual precipitation. Recent research using high-resolution atmospheric model simulations and retrospective predictions has shown that since the 1950's, and more specifically in the last few decades, the mean daily precipitation in the southwestern U.S. during the NAM has followed a decreasing trend. Furthermore, days with more extreme precipitation have intensified. The current work focuses the impact of these long-term changes on the observed small-scale spatial variability of intense precipitation. Since limited long-term high-resolution observational data exist to support such climatological-induced spatial changes in precipitation frequency and intensity, the current work utilizes observations from the USDA-ARS Walnut Gulch Experimental Watershed (WGEW) in southeastern Arizona. Within this 150 km^2 catchment over 90 rain gauges have been installed since the 1950s, measuring at sub-hourly resolution. We have applied geospatial analyses and the kriging interpolation technique to identify long-term changes in the spatial and temporal correlation and anisotropy of intense precipitation. The observed results will be compared with the previously model simulated results, as well as related to large-scale variations in climate patterns, such as the El Niño Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO).

    The objectives were twofold: (a) examine long-term treatment effects in youth receiving 1-session treatment (OST) or educational support (EST) for a specific phobia (SP) and (b) examine the differential predictive and moderation effects of attention-deficit/hyperactivity disorder (ADHD) symptoms on immediate and long-term outcomes following the interventions. Eighty-three children (ages 6-15, 47% female, 89% White) with a SP were randomly assigned to receive OST or EST. Follow up assessments occurred at 1 week, 6 months, 1 year, and 4 years. Hierarchical linear growth modeling (HLGM) was used to explore the association of parent-reported ADHD symptoms, the 2 treatment conditions (i.e., OST vs. EST), and the trajectory of change in the severity of the SP from pretreatment to the 4-year follow-up. Age, conduct problems and learning problems were controlled for in all analyses. A greater immediate reduction in severity rating of the SP was observed in the OST compared to EST, whereas the trajectory of long-term outcomes was similar across conditions over time. Higher levels of ADHD symptoms predicted poor immediate and long-term treatment outcomes across treatment conditions. ADHD symptoms, however, did not moderate the relationship between treatment condition and immediate or long-term treatment outcomes. The results of the study need to be interpreted in light of several study limitations. However, if confirmed, the findings suggest that anxious youth with comorbid ADHD symptoms are less likely to benefit from brief, intensive psychotherapy and may require either longer, standard CBT treatment or adjunctive pharmacotherapy.

    Long-term physical ageing of chalcogenide glasses, which occurs over tens of years, is much less understood than the short-term ageing. With Se-rich underconstrained As 30 Se 70 glass as a model composition (consisting of Se n chains with n≤3 on average), a microscopic model is developed for this phenomenon by combining information from differential scanning calorimetry, extended x-ray absorption fine structure, Raman, and 77 Se solid state nuclear magnetic resonance spectroscopies. The accompanying changes in the electronic structure of these glasses are investigated by x-ray photoelectron spectroscopy. The data suggest ageing from cooperative relaxation, presumably involving bond switching or reconfiguration of As-Se-Se-As fragments

    A long-term follow-up study has been conducted on the physical and intellectual development of 1026 children exposed in utero to diagnostic x-rays and of 1191 non-exposed controls in Beijing, Shanghai and Changchun. The fetal absorbed doses ranged from 11.75 to 42.70 mGy. The results showed that there was no significant difference between the two groups in body height, weight and head circumference compared by standard deviations of individual measured parameters from local normal means. The mean score of an intelligence test in the exposed group was slightly lower than that in the control group with a statistically significant difference. However, the residual radiation effects on IQ were no longer significant on the Hotelling T 2 -test and Student's t-test when confounding factors were identified and taken into account by backward stepwise regression analyses.

  18. Stimulus Intensity-dependent Modulations of Hippocampal Long-term Potentiation by Basolateral Amygdala Priming

    Full Text Available There is growing realization that the relationship between memory and stress/emotionality is complicated, and may include both memory enhancing and memory impairing aspects. It has been suggested that the underlying mechanisms involve amygdalar modulation of hippocampal synaptic plasticity, such as long-term potentiation (LTP. We recently reported that while in CA1 basolateral amygdala (BLA priming impaired theta stimulation induced LTP, it enhanced LTP in the dentate gyrus (DG. However, emotional and stressfull experiences were found to activate synaptic plasticity within the BLA, rasing the possibility that BLA modulation of other brain regions may be altered as well, as it may depend on the way the BLA is activated or is responding. In previous studies BLA priming stimulation was relatively weak (1V, 50 µs pulse duration. In the present study we assessed the effects of two stronger levels of BLA priming stimulation (1V or 2V, 100 µs pulse duration on LTP induction in hippocampal DG and CA1, in anesthetized rats. Results show that 1V-BLA priming stimulation enhanced but 2V-BLA priming stimulation impaired DG LTP; however, both levels of BLA priming stimulation impaired CA1 LTP, suggesting that modulation of hippocampal synaptic plasticity by amygdala is dependent on the degree of amygdala activation. These findings suggest that plasticity induced within the amygdala, by stressful experiences induces a form of metaplasticity that would alter the way the amygdala may modulate memory-related processes in other brain areas, such as the hippocampus.

    To overcome self-control difficulties, people can commit to their health goals by voluntarily accepting deadlines with consequences. In a commitment lottery, the winners are drawn from all participants, but can only claim their prize if they also attained their gym-attendance goals. In a 52-week, three-arm trial across six company gyms, we tested if commitment lotteries with behavioral economic underpinnings would promote physical activity among overweight adults. In previous work, we presented an effective 26-week intervention. In the present paper we analyzed maintenance of goal attainment at 52-week follow-up and the development of weight over time. We compared weight and goal attainment (gym attendance ≥ 2 per week) between three arms that-in the intervention period- consisted of (I) weekly short-term lotteries for 13 weeks; (II) the same short-term lotteries in combination with an additional long-term lottery after 26 weeks; and (III) a control arm without lottery-deadlines. After a successful 26-week intervention, goal attainment declined between weeks 27 and 52 in the long-term lottery arm, but remained higher than in the control group. Goal attainment did not differ between the short-term lottery arm and control arm. Weight declined slightly in all arms in the first 13 weeks of the trial and remained stable from there on. Commitment lotteries can support regular gym attendance up to 52 weeks, but more research is needed to achieve higher levels of maintenance and weight loss.

    To assess whether randomization to 10 years of lifestyle intervention to induce and maintain weight loss improves cognitive function. Randomized controlled clinical trial. Data obtained as part of the Action for Health in Diabetes (Look AHEAD) trial (NCT00017953) and Look AHEAD Continuation study (U01 DK057136-15). Overweight and obese individuals with type 2 diabetes mellitus aged 45 to 76 (N = 3,751). Intensive lifestyle intervention (ILI) for weight loss through reduced caloric intake and increased physical activity compared with a control condition of diabetes support and education (DSE). Certified examiners who were masked to intervention assignment administered a standard battery of cognitive function tests (Modified Mini-Mental State Examination, Rey Auditory Verbal Learning Test, Digit Symbol Coding, Trail-Making Test, Modified Stroop Color-Word Test) to participants 10 to 13 years after enrollment. Assignment to lifestyle intervention was not associated with significantly different overall (P = .10) or domain-specific (all P > .10) cognitive function than assignment to diabetes support and education. Results were fairly consistent across prespecified groups, but there was some evidence of trends for differential intervention effects showing modest harm in ILI in participants with greater body mass index and in individuals with a history of cardiovascular disease. Cognitive function was not associated with changes in weight or fitness (all P > .05). A long-term behavioral weight loss intervention for overweight and obese adults with diabetes mellitus was not associated with cognitive benefit.

    Patients admitted to the intensive care unit (ICU) with acute respiratory failure (ARF) due to COPD have high mortality and morbidity. Acidosis has several harmful effects on hemodynamics and metabolism, and the current knowledge regarding the relationship between respiratory acidosis severity on the short- and long-term survival of COPD patients is limited. We hypothesized that COPD patients with severe acidosis would have a poorer short- and long-term prognosis compared with COPD patients with mild-to-moderate acidosis. This retrospective observational cohort study was conducted in a level III respiratory ICU of a tertiary teaching hospital for chest diseases between December 1, 2013, and December 30, 2014. Subject characteristics, comorbidities, ICU parameters, duration of mechanical ventilation, length of ICU stay, ICU mortality, use of domiciliary noninvasive mechanical ventilation (NIMV) and long-term oxygen therapy (LTOT), and short- and long-term mortality were recorded. Patients were grouped according to their arterial blood gas (ABG) values during ICU admission: severe acidotic (pH≤7.20) and mild-to-moderate acidotic (pH 7.21-7.35). These groups were compared with the recorded data. The mortality predictors were analyzed by logistic regression test in the ICU and the Cox regression test for long-term mortality predictors. During the study period, a total of 312 COPD patients admitted to the ICU with ARF, 69 (72.5% male) in the severe acidosis group and 243 (79% male) in the mild-to-moderate acidosis group, were enrolled. Group demographics, comorbidities, duration of mechanical ventilation, and length of ICU stay were similar in the two groups. The severe acidosis group had a significantly higher rate of NIMV failure (60.7% vs 40%) in the ICU. Mild-to-moderate acidotic COPD patients using LTOT had longer survival after ICU discharge than those without LTOT. On the other hand, severely acidotic COPD patients without LTOT showed shorter survival than

    To assess the reliability of physicians' prognoses for intensive care unit (ICU) survivors with respect to long-term survival and health related quality of life (HRQoL). We performed an observational cohort-study in a single mixed tertiary ICU in The Netherlands. ICU survivors with a length of stay >48h were included. At ICU discharge, one-year prognosis was estimated by physicians using the four-option Sabadell score to record their expectations. The outcome of interest was poor outcome, which was defined as dying within one-year follow-up, or surviving with an EuroQoL5D-3L index <0.4. Among 1399 ICU survivors, 1068 (76%) subjects were expected to have a good outcome; 243 (18%) a poor long-term prognosis; 43 (3%) a poor short-term prognosis, and 45 (3%) to die in hospital (i.e. Sabadell score levels). Poor outcome was observed in 38%, 55%, 86%, and 100% of these groups respectively (concomitant c-index: 0.61). The expected prognosis did not match observed outcome in 365 (36%) patients. This was almost exclusively (99%) due to overoptimism. Physician experience did not affect results. Prognoses estimated by physicians incorrectly predicted long-term survival and HRQoL in one-third of ICU survivors. Moreover, inaccurate prognoses were generally the result of overoptimistic expectations of outcome. Copyright © 2017 Elsevier Inc. All rights reserved.

    Carbon (C) occluded in phytolith (PhytOC) is highly stable at millennium scale and its accumulation in soils can help increase long-term C sequestration. Here, we report that soil PhytOC storage significantly increased with increasing duration under intensive management (mulching and fertilization) in Lei bamboo (Phyllostachys praecox) plantations. The PhytOC storage in 0-40 cm soil layer in bamboo plantations increased by 217 Mg C ha-1, 20 years after being converted from paddy fields. The PhytOC accumulated at 79 kg C ha-1 yr-1, a rate far exceeding the global mean long-term soil C accumulation rate of 24 kg C ha-1 yr-1 reported in the literature. Approximately 86% of the increased PhytOC came from the large amount of mulch applied. Our data clearly demonstrate the decadal scale management effect on PhytOC accumulation, suggesting that heavy mulching is a potential method for increasing long-term organic C storage in soils for mitigating global climate change.

    Long-term field experiments performed in experimental farms are important research tools to assess the soil physical quality (SPQ) given that relatively stable conditions can be expected in these soils. However, different SPQ indicators may sometimes provide redundant or conflicting results, making difficult an SPQ evaluation (Castellini et al., 2014). As a consequence, it is necessary to apply appropriate statistical procedures to obtain a minimum set of key indicators. The study was carried out at the Experimental Farm of CREA-SCA (Foggia) in two long-term field experiments performed on durum wheat. The first long-term experiment is aiming at evaluating the effects of two residue management systems (burning, B or soil incorporation of crop residues, I) while the second at comparing the effect of tillage (conventional tillage, CT) and sod-seeding (direct drilling, DD). In order to take into account both optimal and non-optimal soil conditions, five SPQ indicators were monitored at 5-6 sampling dates during the crop season (i.e., between November and June): soil bulk density (BD), macroporosity (PMAC), air capacity (AC), plant available water capacity (PAWC) and relative field capacity (RFC). Two additional data sets, collected on DD plot in different cropping seasons and in Sicilian soils differing for texture, depth and land use (N=140), were also used with the aim to check the correlation among indicators. Impact of soil management was assessed by comparing SPQ evaluated under different management systems with optimal reference values reported in literature. Two techniques of multivariate analysis (principal component analysis, PCA and stepwise discriminant analysis, SDA) were applied to select the most suitable indicator to facilitate the judgment on SPQ. Regardless of the considered management system, sampling date or auxiliary data set, correlation matrices always showed significant negative relationships between RFC and AC. Decreasing RFC at increasing AC is

    Full Text Available Introduction: Dementia syndromes are an increasing medical and social problem in today’s world. Preservation of the best possible quality of life in dementia patients relies on prolonging their independence in daily life for as long as possible. Dementia patients require increasing support as the disease progresses and will ultimately become dependent on the help of others. Aim of the research: To assess the level of mental and physical performance and nutritional status in patients with dementia syndromes in long-term residential care. Material and methods : The study group comprised 62 patients with dementia syndromes resident in a Medical and Nursing Care Facility in Pustków. Selected aspects of quality of life were investigated with the Barthel scale, GDS scale according to Reissberg, Abbreviated Mental Test Score (AMTS and Mini-Nutritional Assessment (MNA scale. Results: In our study men performed better than women on the Barthel scale, 58% of all patients were rated moderately severe on that scale, 36% were severe and 7% were mild. Assessment of the current severity of dementia on the GDS scale showed that 28% of the patients had very severe dementia, 27% had mild deficits, 27% had moderate deficits, 11% had moderately severe dementia and 6% had borderline dementia. In a mental state assessment according to the AMTS scale, men scored higher than women. This difference indicates less memory deficit and better psychological and physical status among men. With regard to nutritional status, our study revealed a risk of malnutrition in 65% of the patient and actual malnutrition in 7%. Conclusions : The Barthel scale, rating the performance of dementia patients with regard to activities of daily life, classified more than half of the patients as „moderately severe”. Women had lower mean scores than men in the Barthel scale, AMTS scale and GDS scale, indicating that dementia is more prevalent among women than among men. The findings of the

  7. Long-term trends in direct and indirect household energy intensities: a factor in dematerialisation?

    International Nuclear Information System (INIS)

    Vringer, K.; Blok, K.

    2000-01-01

    Dematerialisation is assumed to contribute significantly to the alleviation of environmental problems. One of the possible causes of dematerialisation is a change in the consumption patterns of households. The aim of this article is to analyse changes in consumption patterns of Dutch households in the period between 1948 to 1996 in order to discover whether these changes have influenced the energy intensity of society. Due to the rise in consumption, the total household energy requirement per capita grew on average by 2.4 per cent per year over a period of 48 years (this figure ignores efficiency changes in the supplying sectors). In the same period the total energy intensity of households fluctuated but on average changed from 5.6 to 6.3 MJ/NLG, an increase of 0.25 per cent per year. If we exclude the direct energy consumption we find a slight decline in the indirect energy intensity, namely from 3.8 to 3.6 MJ/NLG ( - 0.14 per cent per year). No significant trends to a lower energy intensity are found and there is no indication of dematerialisation of the consumption patterns. If governments pursue a policy of sustainable development they have to take into account the fact that dematerialisation of the consumption pattern does not seem to be an autonomous process.

    Background Control of soil-transmitted helminth (STH) infections relies on the periodic and long-term administration of anthelmintic drugs to high-risk groups, particularly school-age children living in endemic areas. There is limited data on the effectiveness of long-term periodic anthelmintic treatment on the prevalence of STHs, particularly from operational programmes. The current study investigated the impact of 15 to 17 years of treatment with the broad-spectrum anthelmintic ivermectin, used for the control of onchocerciasis, on STH prevalence and intensity in school-age and pre-school children. Methods and Findings A cross-sectional study was conducted in communities that had received annual or twice-annual ivermectin treatments and geographically adjacent communities that had not received treatment in two districts of Esmeraldas Province in Ecuador. Stool samples were collected from school-age children and examined for STH infection using the Kato-Katz and formol-ether concentration methods. Samples were collected also from pre-school children and examined by the formol-ether concentration method. Data on risk factors for STH infection were collected by parental questionnaire. We sampled a total of 3,705 school-age children (6–16 years) from 31 treated and 27 non-treated communities, and 1,701 pre-school children aged 0–5 years from 18 treated and 18 non-treated communities. Among school-age children, ivermectin treatment had significant effects on the prevalence (adjusted OR =  0.06, 95% CI 0.03–0.14) and intensity of Trichuris trichiura infection (adjusted RR = 0.28, 95% CI 0.11–0.70), but appeared to have no impact on Ascaris lumbricoides or hookworm infection. Reduced prevalence and intensities of T. trichiura infection were observed among children not eligible to receive ivermectina, providing some evidence of reduced transmission of T. trichiura infection in communities receiving mass ivermectin treatments.

    Long-term intensive gymnastic training can induce brain structural and functional reorganization. Previous studies have identified structural and functional network differences between world class gymnasts (WCGs) and non-athletes at the whole-brain level. However, it is still unclear how interactions within and between functional networks are affected by long-term intensive gymnastic training. We examined both intra- and inter-network functional connectivity of gymnasts relative to non-athletes using resting-state fMRI (R-fMRI). R-fMRI data were acquired from 13 WCGs and 14 non-athlete controls. Group-independent component analysis (ICA) was adopted to decompose the R-fMRI data into spatial independent components and associated time courses. An automatic component identification method was used to identify components of interest associated with resting-state networks (RSNs). We identified nine RSNs, the basal ganglia network (BG), sensorimotor network (SMN), cerebellum (CB), anterior and posterior default mode networks (aDMN/pDMN), left and right fronto-parietal networks (lFPN/rFPN), primary visual network (PVN), and extrastriate visual network (EVN). Statistical analyses revealed that the intra-network functional connectivity was significantly decreased within the BG, aDMN, lFPN, and rFPN, but increased within the EVN in the WCGs compared to the controls. In addition, the WCGs showed uniformly decreased inter-network functional connectivity between SMN and BG, CB, and PVN, BG and PVN, and pDMN and rFPN compared to the controls. We interpret this generally weaker intra- and inter-network functional connectivity in WCGs during the resting state as a result of greater efficiency in the WCGs' brain associated with long-term motor skill training.

    Autobiographical memories can be recalled from either a field (first-person) or an observer (third-person) perspective. Previous studies have reported that field-to-observer perspective change reduced the emotional intensity of recalled events. In the present study, we examined whether this effect has a long duration by employing follow-up measurements. The participants were asked to recall the same events repeatedly across three sessions (S1, S2, and S3): S2 was conducted about three days after S1, and S3 was conducted about four weeks after S2. The results showed a reduction in the emotional intensity of the recalled events when the perspective was changed from field to observer at S2. More importantly, this reduction in emotional intensity persisted until S3. These effects were not observed under observer-to-field perspective change at S2. These results suggest that observer perspective taking can cause plastic change in the autobiographical memory system.

    We describe dynamical processes in continuous media with a long-term memory. Our consideration is based on a stochastic subordination idea and concerns two physical examples in detail. First we study a temporal evolution of the species concentration in a trapping reaction in which a diffusing reactant is surrounded by a sea of randomly moving traps. The analysis uses the random-variable formalism of anomalous diffusive processes. We find that the empirical trapping-reaction law, according to which the reactant concentration decreases in time as a product of an exponential and a stretched exponential function, can be explained by a two-time scale subordination of random processes. Another example is connected with a state equation for continuous media with memory. If the pressure and the density of a medium are subordinated in two different random processes, then the ordinary state equation becomes fractional with two-time scales. This allows one to arrive at the Bagley-Torvik type of state equation

    Exposure to loud sounds has become increasingly common. The most common consequences of loud sound exposure are deafness and tinnitus, but emotional and cognitive problems are also associated with loud sound exposure. Loud sounds can activate the hipothalamic-pituitary-adrenal axis resulting in the secretion of corticosterone, which affects hippocampal synaptic plasticity. Previously we have shown that long-term exposure to short episodes of high intensity sound inhibited hippocampal long-term potentiation (LTP) without affecting spatial learning and memory. Here we aimed to study the impact of short term loud sound exposure on hippocampal synaptic plasticity and function. We found that a single minute of 110 dB sound inhibits hippocampal Schaffer-CA1 LTP for 24 hours. This effect did not occur with an 80-dB sound exposure, was not correlated with corticosterone secretion and was also observed in the perforant-dentate gyrus synapse. We found that despite the deficit in the LTP these animals presented normal spatial learning and memory and fear conditioning. We conclude that a single episode of high-intensity sound impairs hippocampal LTP, without impairing memory and learning. Our results show that the hippocampus is very responsive to loud sounds which can have a potential, but not yet identified, impact on its function.

    To investigate the impact of a multicomponent exercise program on anthropometry, physical function, and physical activity on older adults living in long-term nursing homes (LTNH), we conducted a randomized controlled trial involving 112 participants aged 84.9 ± 6.9 years. Participants were randomly assigned to an intervention (IG) or control group (CG). The IG participated in a 3-month multicomponent exercise intervention focused on strength, balance, stretching exercises, and walking recommendations. Subjects in the CG participated in routine activities. Analyses of outcome parameters were performed in the entire sample and in two subgroups, classified according to participants' physical function score at baseline. The group-by-time interaction, favoring the IG, was significant for the entire sample and for the participants in the low physical function subgroup for the following parameters: waist circumference, 30-s chair-stand, arm-curl, 8-ft timed up-and-go, SPPB score, gait speed, and Berg scale (p < .05). In participants with higher physical function at baseline, significant group-by-time interaction was observed in the SPPB score and Berg scale (p < .05). When differences were analyzed within groups, the IG maintained or improved in all assessed parameters, while participants in the CG showed a marked decline. Our study showed that a multicomponent exercise program is effective for older people living in LTNH. This is especially relevant in those with lower physical function scores. The lower efficacy of the program in participants with better function might be due to the insufficient exercise demands of our intervention for more fit residents. Future studies should analyze the effects of programs with higher intensities in older people with intermediate to high physical function. Copyright © 2018 Elsevier Inc. All rights reserved.

    Cleaning and disinfecting fomites can effectively remove/kill pathogens on surfaces, but studies have shown that more than one-half the time, surfaces are not adequately cleaned or are recontaminated within minutes. This study evaluated a product designed to create a long-lasting surface coating that provides continuous disinfecting action. This study was performed in an intensive care unit (ICU) in a major hospital. Various sites within the ICU were cultured before treatment and then at 1, 2, 4, 8, and 15 weeks after application of an antimicrobial coating. Samples were cultured for total bacteria, as well as Clostridium difficile, methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococcus, and carbapenemase-resistant Enterobacteriaceae. The average bacterial count on all treated surfaces was reduced by >99% (2 logs) for at least 8 weeks after treatment. Overall, average levels of bacteria never returned to those observed before treatment even after 15 weeks. Antibiotic-resistant bacteria were found on 25% of the sites tested before treatment, but were isolated at only 1 site during the 15 weeks after treatment. The product assessed in this study was found to have persisted over 15 weeks in reducing the total number of bacteria and antibiotic resistant bacteria on surfaces within an ICU.

    This paper presents the first standardized physical environmental assessment tool titled Dining Environment Audit Protocol (DEAP) specifically designed for dining spaces in care homes and reports the results of its psychometric properties. Items rated include: adequacy of lighting, glare, personal control, clutter, staff supervision support, restraint use, and seating arrangement option for social interaction. Two scales summarize the prior items and rate the overall homelikeness and functionality of the space. Ten dining rooms in three long-term care homes were selected for assessment. Data were collected over 11 days across 5 weeks. Two trained assessors completed DEAP independently on the same day. Interrater-reliability was completed for lighting, glare, space, homelike aspects, seating arrangements and the two summary scales, homelikeness and functionality of the space. For categorical measures, measure responses were dichotomized at logical points and Cohen's Kappa and concordance on ratings were determined. The two overall rating scales on homelikeness and functionality of space were found to be reliable intraclass correlation coefficient (ICC) (~0.7). The mean rating for homelikeness for Assessor 1 was 3.5 (SD 1.35) and for functionality of the room was 5.3. (SD 0.82; median 5.5). The findings indicate that the tool's interrater-reliability scores are promising. The high concordance on the overall scores for homelikeness and functionality is indicative of the strength of the individual items in generating a reliable global assessment score on these two important aspects of the dining space. © The Author 2017.

    Decision regret (DR) may occur when a patient believes their outcome would have been better if they had decided differently about their management. Although some studies investigate DR after treatment for localised prostate cancer, none report DR in patients undergoing surgery and post-prostatectomy radiotherapy. We evaluated DR in this group of patients overall, and for specific components of therapy. We surveyed 83 patients, with minimum 5 years follow-up, treated with radical prostatectomy (RP) and post-prostatectomy image-guided intensity-modulated radiotherapy (IG-IMRT) to 64-66 Gy following www.EviQ.org.au protocols. A validated questionnaire identified DR if men either indicated that they would have been better off had they chosen another treatment, or they wished they could change their mind about treatment. There was an 85.5% response rate, with median follow-up post-IMRT 78 months. Adjuvant IG-IMRT was used in 28% of patients, salvage in 72% and ADT in 48%. A total of 70% of patients remained disease-free. Overall, 16.9% of patients expressed DR for treatment, with fourfold more regret for the RP component of treatment compared to radiotherapy (16.9% vs 4.2%, P = 0.01). DR for androgen deprivation was 14.3%. Patients were regretful of surgery due to toxicity, not being adequately informed about radiotherapy as an alternative, positive margins and surgery costs (83%, 33%, 25% and 8% of regretful patients respectively). Toxicity caused DR in the three radiotherapy-regretful and four ADT-regretful patients. Patients were twice as regretful overall, and of surgery, for salvage vs adjuvant approaches (both 19.6% vs 10.0%). Decision regret after RP and post-prostatectomy IG-IMRT is uncommon, although patients regret RP more than post-operative IG-IMRT. This should reassure urologists referring patients for post-prostatectomy IG-IMRT, particularly in the immediate adjuvant setting. Other implications include appropriate patient selection for RP (and

    To assess the prospective associations between self-reported physical capacity and risk of long-term sickness absence among female health care workers. Female health care workers answered a questionnaire about physical capacity and were followed in a national register of sickness absence lasting for two or more consecutive weeks during 1-year follow-up. Using Cox regression hazard ratio analyses adjusted for age, smoking, body mass index, physical workload, job seniority, psychosocial work conditions, and previous sickness absence, we modeled risk estimates for sickness absence from low and medium physical capacity. Low and medium aerobic fitness, low muscle strength, low flexibility, and low overall physical capacity significantly increased the risk for sickness absence with 20% to 34% compared with health care workers with high capacity. Low physical capacity increases the risk of long-term sickness absence among female health care workers.

    Full Text Available Abstract Background Modern methods in intensive care medicine often enable the survival of older critically ill patients. The short-term outcomes for patients treated in intensive care units (ICUs, such as survival to hospital discharge, are well documented. However, relatively little is known about subsequent long-term outcomes. Pain, anxiety and agitation are important stress factors for many critically ill patients. There are very few studies concerned with pain, anxiety and agitation and the consequences in older critically ill patients. The overall aim of this study is to identify how an ICU stay influences an older person's experiences later in life. More specific, this study has the following objectives: (1 to explore the relationship between pain, anxiety and agitation during ICU stays and experiences of the same symptoms in later life; and (2 to explore the associations between pain, anxiety and agitation experienced during ICU stays and their effect on subsequent health-related quality of life, use of the health care system (readmissions, doctor visits, rehabilitation, medication use, living situation, and survival after discharge and at 6 and 12 months of follow-up. Methods/Design A prospective, longitudinal study will be used for this study. A total of 150 older critically ill patients in the ICU will participate (ICU group. Pain, anxiety, agitation, morbidity, mortality, use of the health care system, and health-related quality of life will be measured at 3 intervals after a baseline assessment. Baseline measurements will be taken 48 hours after ICU admission and one week thereafter. Follow-up measurements will take place 6 months and 12 months after discharge from the ICU. To be able to interpret trends in scores on outcome variables in the ICU group, a comparison group of 150 participants, matched by age and gender, recruited from the Swiss population, will be interviewed at the same intervals as the ICU group.

    To evaluate any change in self-reported level of physical activity in patients receiving a general physical exercise programme in addition to disease-specific physiotherapy treatment. Pre-post-intervention study. Outpatient physiotherapy clinics. One hundred and ninety patients with long-term musculoskeletal conditions attending outpatient physiotherapy were recruited from seven physiotherapy clinics. Physiotherapy including disease-specific modalities and a general individually tailored exercise programme. Patients were evaluated at baseline and at the end of the programme. International Physical Activity Questionnaire short form (IPAQ-sf) and COOP WONCA functional assessment charts. Forty-two patients were excluded from the analysis because they did not complete the IPAQ-sf correctly or dropped out during the treatment period. There was a significant increase in the number of metabolic equivalent task (MET)-min/week for vigorous and moderate-intensity activities, walking and total physical activity. The number of exercise sessions per week increased from 1.8 [standard deviation (SD) 0.9] to 2.2 (SD 1.2) (P=0.001). The proportion of patients with a low level of physical activity decreased by 12%, and the proportion of the participants who did not/could not exercise decreased from 26% to 8%. The COOP WONCA charts showed significant improvements in the physical fitness, feelings, daily activities and social activities items. A significant increase was found in the number of MET-min/week for all activity levels. Therefore, a general physical exercise programme initiated by a physiotherapist led to a positive change in level of physical activity. Copyright © 2014 Chartered Society of Physiotherapy.

  6. The relationship between energy intensity and income levels: Forecasting long term energy demand in Asian emerging countries

    International Nuclear Information System (INIS)

    Galli, R.; Univ. della Svizzera Italiana, Lugano

    1998-01-01

    This paper analyzes long-term trends in energy intensity for ten Asian emerging countries to test for a non-monotonic relationship between energy intensity and income in the author's sample. Energy demand functions are estimated during 1973--1990 using a quadratic function of log income. The long-run coefficient on squared income is found to be negative and significant, indicating a change in trend of energy intensity. The estimates are then used to evaluate a medium-term forecast of energy demand in the Asian countries, using both a log-linear and a quadratic model. It is found that in medium to high income countries the quadratic model performs better than the log-linear, with an average error of 9% against 43% in 1995. For the region as a whole, the quadratic model appears more adequate with a forecast error of 16% against 28% in 1995. These results are consistent with a process of dematerialization, which occurs as a result of a reduction of resource use per unit of GDP once an economy passes some threshold level of GDP per capita

    This paper is a summary of the observations of the cosmic X-ray sky performed by the MIT 1-40-keV X-ray detectors on OSO 7 between October 1971 and May 1973. Specifically, mean intensities or upper limits of all third Uhuru or OSO 7 cataloged sources (185 sources) in the 3-10-keV range are computed. For those sources for which a statistically significant (greater than 20) intensity was found in the 3-10-keV band (138 sources), further intensity determinations were made in the 1-15-keV, 1-6-keV, and 15-40-keV energy bands. Graphs and other simple techniques are provided to aid the user in converting the observed counting rates to convenient units and in determining spectral parameters. Long-term light curves (counting rates in one or more energy bands as a function of time) are plotted for 86 of the brighter sources.

    Full Text Available Abstract Background The objective of this retrospective study is to investigate laryngeal preservation and long-term treatment results in hypopharyngeal carcinoma treated with intensity-modulated radiotherapy (IMRT combined with chemotherapy. Methods Twenty-seven patients with hypopharyngeal carcinoma (stage II-IV were enrolled and underwent concurrent chemoradiotherapy. The chemotherapy regimens were monthly cisplatin and 5-fluorouracil for six patients and weekly cisplatin for 19 patients. All patients were treated with IMRT with simultaneous integrated boost technique. Acute and late toxicities were recorded based on CTCAE 3.0 (Common Terminology Criteria for Adverse Events. Results The median follow-up time for survivors was 53.0 months (range 36-82 months. The initial complete response rate was 85.2%, with a laryngeal preservation rate of 63.0%. The 5-year functional laryngeal, local-regional control, disease-free and overall survival rates were 59.7%, 63.3%, 51.0% and 34.8%, respectively. The most common greater than or equal to grade 3 acute and late effects were dysphagia (63.0%, 17 of 27 patients and laryngeal stricture (18.5%, 5 of 27 patients, respectively. Patients belonging to the high risk group showed significantly higher risk of tracheostomy compared to the low risk group (p = 0.014. Conclusions After long-term follow-up, our results confirmed that patients with hypopharyngeal carcinoma treated with IMRT concurrent with platinum-based chemotherapy attain high functional laryngeal and local-regional control survival rates. However, the late effect of laryngeal stricture remains a problem, particularly for high risk group patients.

    High-intensity sound can induce seizures in susceptible animals. After repeated acoustic stimuli changes in behavioural seizure repertoire and epileptic EEG activity might be seen in recruited limbic and forebrain structures, a phenomenon known as audiogenic kindling. It is postulated that audiogenic kindling can produce synaptic plasticity events leading to the spread of epileptogenic activity to the limbic system. In order to test this hypothesis, we investigated if long-term potentiation (LTP) of hippocampal Schaffer-CA1 synapses and spatial navigation memory are altered by a repeated high-intensity sound stimulation (HISS) protocol, consisting of one-minute 120 dB broadband noise applied twice a day for 10 days, in normal Wistar rats and in audiogenic seizure-prone rats (Wistar Audiogenic Rats - WARs). After HISS all WARs exhibited midbrain seizures and 50% of these animals developed limbic recruitment, while only 26% of Wistar rats presented midbrain seizures and none of them had limbic recruitment. In naïve animals, LTP in hippocampal CA1 neurons was induced by 50- or 100-Hz high-frequency stimulation of Schaffer fibres in slices from both Wistar and WAR animals similarly. Surprisingly, HISS suppressed LTP in CA1 neurons in slices from Wistar rats that did not present any seizure, and inhibited LTP in slices from Wistar rats with only midbrain seizures. However HISS had no effect on LTP in CA1 neurons from slices of WARs. Interestingly HISS did not alter spatial navigation and memory in both strains. These findings show that repeated high-intensity sound stimulation prevent LTP of Schaffer-CA1 synapses from Wistar rats, without affecting spatial memory. This effect was not seen in hippocampi from audiogenic seizure-prone WARs. In WARs the link between auditory stimulation and hippocampal LTP seems to be disrupted which could be relevant for the susceptibility to seizures in this strain. Copyright © 2015 IBRO.

    Full Text Available Abstract Background Previous studies have demonstrated positive effects of short-term, intensive weight-loss programs in obese children. Objectives We evaluated the long-term effects of a non-intensive weight management program on the BMI, glycemic measures and lipid profiles of obese youth. Methods Retrospective chart review of 61 obese children followed at our Weight Management Center. During visits, dietary changes and regular physical activity were recommended. Anthropometric and laboratory parameters were evaluated. Results At the initial visit, the mean age was 11.1 ± 2.6 years. The follow-up period was 47.3 ± 11.1 months; the number of outpatient visits per year (OV/yr was 2.9 ± 0.9. At the end of the follow-up, the whole group exhibited decreased BMI z-score and LDL-cholesterol when compared to the initial visit. In the subset of subjects in whom OGTT was performed, 2-hour glucose and peak insulin were decreased. Compared to children with ≤ 2 OV/year, those with > 2 OV/year (3.19 ± 0.7 exhibited a significant decrease in their BMI z-score, LDL-cholesterol, 2-hour glucose, and peak insulin. Conclusions Our study suggests that a periodical (~ 3 OV/yr evaluation in a non-intensive, long-term weight management program may significantly improve the degree of obesity and cardiovascular risk factors in childhood.

    Physical activity has been effective in enhancing quality of life (QOL) of older adults over relatively short periods of time. However, little is known about the long-term effects of physical activity and even less about the possible mediators of this relationship. We examined the mediating effects of psychological variables on the relationship between physical activity and global QOL (satisfaction with life) in older adults over a 4-year period. Participants (N = 174, M age = 66.7 years) completed a battery of psychosocial measures at 1 and 5 years following enrollment in a 6-month randomized controlled exercise trial. Panel analysis conducted within a covariance modeling framework indicated that physical activity was related to self-efficacy, physical self-esteem, and positive affect at 1 year, and in turn, greater levels of self-efficacy and positive affect were associated with higher levels of QOL. Analyses indicated that changes in physical activity over the 4-year period were related to increases in physical self-esteem and positive affect, but only positive affect directly influenced improvements in QOL. The findings lend support to the position that physical activity effects on QOL are in part mediated by intermediate psychological outcomes and that physical activity can have long-term effects on well-being.

    Communication in the intensive care unit (ICU) is an important component of quality ICU care. In this report, we evaluate the long-term effects of a quality improvement (QI) initiative, based on the VALUE communication strategy, designed to improve communication with family members of critically ill patients. We implemented a multifaceted intervention to improve communication in the ICU and measured processes of care. Quality improvement components included posted VALUE placards, templated progress note inclusive of communication documentation, and a daily rounding checklist prompt. We evaluated care for all patients cared for by the intensivists during three separate 3 week periods, pre, post, and 3 years following the initial intervention. Care delivery was assessed in 38 patients and their families in the pre-intervention sample, 27 in the post-intervention period, and 41 in follow-up. Process measures of communication showed improvement across the evaluation periods, for example, daily updates increased from pre 62% to post 76% to current 84% of opportunities. Our evaluation of this quality improvement project suggests persistence and continued improvements in the delivery of measured aspects of ICU family communication. Maintenance with point-of-care-tools may account for some of the persistence and continued improvements. Copyright © 2014 Elsevier Inc. All rights reserved.

  19. Long-term dynamics of tropical walking sticks in response to multiple large-scale and intense disturbances.

    Understanding the effects of disturbance and secondary succession on spatio-temporal patterns in the abundance of species is stymied by a lack of long-term demographic data, especially in response to infrequent and high intensity disturbances, such as hurricanes. Moreover, resistance and resilience to hurricane-induced disturbance may be mediated by legacies of previous land use, although such interactive effects are poorly understood, especially in tropical environments. We address these central issues in disturbance ecology by analyzing an extensive dataset, spanning the impacts of Hurricanes Hugo and Georges, on the abundance of a Neotropical walking stick, Lamponius portoricensis, in tabonuco rainforest of Puerto Rico during the wet and dry seasons from 1991 to 2007. By synthesizing data from two proximate sites in tabonuco forest, we show that resistance to Hurricane Hugo (97% reduction in abundance) was much less than resistance to Hurricane Georges (21% reduction in abundance). Based on a powerful statistical approach (generalized linear mixed-effects models with Poisson error terms), we documented that the temporal trajectories of abundance during secondary succession (i.e., patterns of resilience) differed between hurricanes and among historical land use categories, but that the effects of hurricanes and land use histories were independent of each other. These complex results likely arise because of differences in the intensities of the two hurricanes with respect to microclimatic effects (temperature and moisture) in the forest understory, as well as to time-lags in the response of L. portoricensis to changes in the abundance and distribution of preferred food plants (Piper) in post-hurricane environments.

    The broader purpose of this study was to examine the temporal effects of high-intensity exercise on learning, short-term and long-term retrospective memory and prospective memory. Among a sample of 88 young adult participants, 22 were randomized into one of four different groups: exercise before learning, control group, exercise during learning, and exercise after learning. The retrospective assessments (learning, short-term and long-term memory) were assessed using the Rey Auditory Verbal Learning Test. Long-term memory including a 20-min and 24-hr follow-up assessment. Prospective memory was assessed using a time-based procedure by having participants contact (via phone) the researchers at a follow-up time period. The exercise stimulus included a 15-min bout of progressive maximal exertion treadmill exercise. High-intensity exercise prior to memory encoding (vs. exercise during memory encoding or consolidation) was effective in enhancing long-term memory (for both 20-min and 24-h follow-up assessments). We did not observe a differential temporal effect of high-intensity exercise on short-term memory (immediate post-memory encoding), learning or prospective memory. The timing of high-intensity exercise may play an important role in facilitating long-term memory. © 2017 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

However, existing studies showed that physical restraint not only has inadequate effect of protection but also has negative effects on residents. To analyzes the impact of educational program on the physical restraint use in long-term care facilities. A systematic review with meta-analysis and meta-regression. Eight databases, including Cochrane Library, ProQuest, PubMed, EMBASE, EBSCO, Web of Science, Ovid Medline and Physiotherapy Evidence Database (PEDro), were searched up to January 2017. Eligible studies were classified by intervention and accessed for quality using the Quality Assessment Tool for quantitative studies. Sixteen research articles were eligible in the final review; 10 randomize control trail studies were included in the analysis. The meta-analysis revealed that the use of physical restraint was significantly less often in the experimental (education) group (OR = 0.55, 95% CI: 0.39 to 0.78, p education would have decreased the effect of the restraint educational program (β: 0.08, p = 0.002); instead, the longer education period and more times of education would have a stronger effect of reducing the use of physical restraint (β: -0.07, p educational program had an effect on the reduced use of physical restraint. The results of meta-regression suggest that long-term care facilities should provide a continuous education program of physical restraint for caregivers. Copyright © 2017.

    In this study, we explore directly exposed terrorism survivors' mental health and health status, healthcare utilization, alcohol and tobacco use, and posttraumatic growth 18½ years postdisaster. Telephone surveys compared terrorism survivors and nonexposed community control subjects, using Hopkins Symptom Checklist, Breslau's PTSD screen, Posttraumatic Growth Inventory, and Health Status Questionnaire 12. Statistical analyses included multivariable logistic regression and linear modeling. Survivors, more than 80% injured, reported more anxiety and depression symptoms than did control subjects, with survivors' anxiety and depression associated with heavy drinking (≥5 drinks) and worse mental health and social functioning. While survivors had continued posttraumatic stress disorder symptoms (32 [23.2%] met probable posttraumatic stress disorder threshold), they also reported posttraumatic growth. Survivors had more care from physical, speech, respiratory, and occupational therapists. In this unprecedented long-term assessment, survivors' psychiatric symptoms, alcohol use, and ancillary health service utilization suggest unmet mental health and health needs. Extended recovery efforts might benefit from maximizing positive growth and coping.

    Differential scanning calorimetry (DSC) measurements were performed to investigate the effects of long-term physical aging on kinetic parameters of the pharmaceutical drug (Flutab). Kinetics parameters such as activation energy (E) and fragility parameter (m) of the glass transition for aged and rejuvenated glasses were determined using different kinetic models. Evidence of variation of E with temperature is presented. It is shown in this work that natural storage of the drug introduced significant physical aging as indicated by changes in the glass transition temperature, activation energy and fragility parameter.

    Despite the benefits of physical activity, residents living in long-term care (LTC) are relatively sedentary. Designing successful physical activity and restorative care programs requires a good understanding of implementation barriers. A database search (2002-2013) yielded seven studies (nine articles) that met our inclusion criteria. We also reviewed 31 randomized controlled trials (RCTs) to determine if the authors explicitly discussed the barriers encountered while implementing their interventions. Eleven RCTs (13 articles) included a discussion of the barriers. Hence, a total of 18 studies (22 articles) were included in this review. Barriers occurred at resident (e.g., health status), environmental (e.g., lack of space for physical activity), and organizational (e.g., staffing and funding constraints) levels. These barriers intersect to adversely affect the physical activity of older people living in LTC. Future studies targeting physical activity interventions for residents living in LTC are needed to address these multiple levels of influence.

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.

    To assess the catch-up growth of long-term physically neglected and emotionally abused preschool male children who have entered foster residential care and remained 1 year after initial placement. Longitudinal study over a 7-year period (1994-2001). So that a child was eligible for the study, three selection criteria were included: (1) aged between 24 and 48 months at the time of entry into residential facility, (2) having suffered both long-term (more than 6 months) physically neglected and emotionally abused, and (3) having stayed in foster care for 1 year after initial placement. Weight, height, and head circumference were established upon entry and re-assessed 1 year after initial placement, calculating the annual growth velocity. Results were compared with normal regional longitudinal standards of reference (Z score). Student's t test was used to assess statistically significant differences. During the study period, 87 children aged between 24 and 48 months (54 male/33 female) were admitted to residential facility after having suffered both long-term physical neglect and emotional abuse. Nevertheless, only 20 children (23% of the total admissions) met the third selection criteria (having remained 1 year after initial placement). Of these children, all were males and at placement they were between the ages of 30 and 42 months, with an average age of 36 months (1.9 SD). At placement, the analyzed parameters were below the normal standards, showing a statistically significant difference for height (Z score = -1.29; p = .008) and weight (Z score = -.75; p = .038). The annual growth velocity for all parameters was above the normal standards showing a statistically significant difference for height (Z score = +1.43; p = .009). One year after initial placement, the significant differences for height (Z score = -.68; p = .102) and weight (Z score = -.31; p = .435) with respect to the normal standards disappeared, though still remained below, showing a significant

    Previous studies have demonstrated that high-intensity interval training (HIT) is superior to moderate-continuous exercise in general and in cardiovascular diseases. Recently, we also found HIT safe and efficient after heart transplantation (HTx). This study reports the 5-year long-term effects. Forty-one HTx patients who had completed the previous 12-month randomized controlled trial, comparing HIT intervention with usual care, were eligible. In particular, we measured VO 2peak , muscular capacity, intravascular ultrasound, and questionnaires measuring physical and mental health. The baseline mean±SD values were as follows: age; 49.1±16.5 years, men; 68%, time since HTx: 4.1±2.2 years. Within the HIT group, initial VO 2peak increased significantly from 27.7±5.7 to 31.2±5.3 mL/kg/min. However, during the next 4 years, VO 2peak decreased to 26.0±6.2 mL/kg/min. The control group showed slightly decreasing VO 2peak values during the entire 5-year period. The HIT group reported significantly less anxiety symptoms, but there were no long-term differences in VO 2peak , muscular capacity, or cardiac allograft vasculopathy between the groups. The similar VO 2peak values correspond to our findings of similar everyday activity. Our findings suggest that intermittent periods of HIT may be necessary to maintain the initial benefits gained from the intervention. However, HIT probably reduces the burden of anxiety, which is a frequent health issue following HTx. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    A taskforce, under the auspices of The International Association of Gerontology and Geriatrics-Global Aging Research Network (IAGG-GARN) and the IAGG European Region Clinical Section, composed of experts from the fields of exercise science and geriatrics, met in Toulouse, in December 2015, with the aim of establishing recommendations of physical activity and exercise for older adults living in long-term care facilities (LTCFs). Due to the high heterogeneity in terms of functional ability and cognitive function that characterizes older adults living in LTCFs, taskforce members established 2 sets of recommendations: recommendations for reducing sedentary behaviors for all LTCF residents and recommendations for defining specific, evidence-based guidelines for exercise training for subgroups of LTCF residents. To promote a successful implementation of recommendations, taskforce experts highlighted the importance of promoting residents' motivation and pleasure, the key factors that can be increased when taking into account residents' desires, preferences, beliefs, and attitudes toward physical activity and exercise. The importance of organizational factors related to LTCFs and health care systems were recognized by the experts. In conclusion, this taskforce report proposes standards for the elaboration of strategies to increase physical activity as well as to prescribe exercise programs for older adults living in LTCFs. This report should be used as a guide for professionals working in LTCF settings. Copyright © 2016 AMDA – The Society for Post-Acute and Long-Term Care Medicine. Published by Elsevier Inc.

    Full Text Available Introduction. This paper reports results of an investigation into the needs of persons with disabilities wanting to participate in the use of virtual communities. The aim was to investigate 'how virtual communities for persons with long-term, severe physical disabilities can best be facilitated'? Method. A Grounded Theory approach was adopted to inform the investigation. In- depth interviews were conducted with twelve persons with paraplegia, quadriplegia or other severe, long-term physical or mobility disabilities and six health care professionals, service providers, information personnel and policy advisers who were involved in their well-being. Analysis. Rich explanations were derived about the information and communication technology (ICT usage and the technologies' contributions towards restoration of sense of control over their lives. Results. The primary outcome of the investigation is a theory regarding the character of virtual communities for the disabled. The theory is represented as a Virtual Community Model. The model identifies: the need for 'a sense of control' as the foundation element of virtual communities for the disabled; the key domains in which disabled people participate in virtual communities; and the barriers and enablers to their participation. Conclusion. The model provides a framework which can be used by interest groups and other organizations to facilitate the development of virtual communities for persons with severe physical disabilities. The six key types of community need to be represented in such virtual communities if a full 'sense of control' is to be achieved by disabled persons.

    Purpose: Reports of intensity-modulated radiotherapy (IMRT) for early-stage nasopharyngeal carcinoma (NPC) have been limited. The present study evaluated the long-term survival outcomes and toxicity of early-stage NPC patients treated with IMRT alone. Methods and Materials: Between February 2001 and January 2008, 198 early-stage (T1-T2bN0-N1M0) NPC patients had undergone IMRT alone. The data from these patients were retrospectively analyzed. The patients were treated to 68 Gy at 2.27 Gy/fraction prescribed to the planning target volume of the primary nasopharygeal gross tumor volume. The Radiation Therapy Oncology Group scoring system was used to assess the toxicity. Results: At a median follow-up of 50.9 months (range, 12-104), the 5-year estimated disease-specific survival, local recurrence-free survival, and distant metastasis-free survival rate was 97.3%, 97.7%, and 97.8%, respectively. The 5-year local recurrence-free survival rate was 100% for those with Stage T1 and T2a and 94.2% for those with Stage T2b lesions (p = 0.252). The 5-year distant metastasis-free survival rate for Stage T1N0, T2N0, T1N1, and T2N1 patients was 100%, 98.8%, 100%, and 93.8%, respectively (p = .073). All local recurrence occurred in patients with T2b lesions. Five patients developed distant metastasis. Of these 5 patients, 4 had had Stage T2bN1 disease and 1 had had Stage T2bN0 disease with retropharyngeal lymph node involvement. The most common acute toxicities were mainly Grade 1 or 2. At 24 months after IMRT, no Grade 3 or 4 xerostomia had developed, and 62 (96.9%) of 64 evaluated patients were free of trismus; only 2 patients (3.1%) had Grade 1 trismus. Radiation encephalopathy and cranial nerve injury were not observed. Conclusions: IMRT alone for Stage T1N0, T2N0, T1N1, and T2N1 yielded satisfactory survival outcomes with acceptable toxicity, and no differences were found in survival outcomes among these four subgroups. Patients with Stage T2b lesions might have relatively

The meta-analysis revealed that the use of physical restraint was significantly less often in the experimental (education group (OR = 0.55, 95% CI: 0.39 to 0.78, p < 0.001 compared to the control group. Meta-regression revealed the period of post education would have decreased the effect of the restraint educational program (β: 0.08, p = 0.002; instead, the longer education period and more times of education would have a stronger effect of reducing the use of physical restraint (β: −0.07, p < 0.001; β: −0.04, p = 0.056. The educational program had an effect on the reduced use of physical restraint. The results of meta-regression suggest that long-term care facilities should provide a continuous education program of physical restraint for caregivers.

    To identify explanatory factors for the association between depression at 3 months after stroke and physical disability at 3 years. Data from the South London Stroke Register (1998-2013) were used. Patients (n = 3,612) were assessed at stroke onset. Follow-up at 3 months included assessment for depression with the Hospital Anxiety and Depression scale (scores ≥ 7 = depression), physical disability (Barthel index) cognitive function, smoking habit, selective serotonin reuptake inhibitors (SSRIs) use, perception of recovery and social support. Physical disability was reassessed at 3 years. The associations between depression at 3 months and physical disability at 3 years were estimated with multinomial regression adjusting for age, gender, ethnicity, stroke severity and possible explanatory factors for the association (introduced in the models first individually and then sequentially): pre-stroke medical history and physical disability, cognitive function, smoking, SSRIs, perception of recovery and social support at 3 months. One thousand three hundred and seven survivors were assessed at 3 months, of which 418 (32.0%) had depression. Survivors with depression had a higher physical disability rate at 3 years. These associations remained significant after adjustment for individual explanatory factors but were not significant after adjustment for combined explanatory factors. Physical disability at 3 months was a relevant explanatory factor for this association. SSRIs were associated with severe, relative risk: 6.62 (2.92-15.02) P disability, relative risk: 3.45 (1.58-7.52) P = 0.002, at 3 years. The association between depression and physical disability appears to be multifactorial. The use of SSRIs after stroke requires further research. © The Author 2015.

    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.

    Individual barriers to weight loss and physical activity goals in the Diabetes Prevention Program, a randomized trial with 3.2 years average treatment duration, have not been previously reported. Evaluating barriers and the lifestyle coaching approaches used to improve adherence in a large, diverse participant cohort can inform dissemination efforts. Lifestyle coaches documented barriers and approaches after each session (mean session attendance = 50.3 ± 21.8). Subjects were 1076 intensive lifestyle participants (mean age = 50.6 years; mean BMI = 33.9 kg/m²; 68% female, 48% non-Caucasian). Barriers and approaches used to improve adherence were ranked by the percentage of the cohort for whom they applied. Barrier groupings were also analyzed in relation to baseline demographic characteristics. Top weight loss barriers reported were problems with self-monitoring (58%); social cues (58%); holidays (54%); low activity (48%); and internal cues (thought/mood) (44%). Top activity barriers were holidays (51%); time management (50%); internal cues (30%); illness (29%), and motivation (26%). The percentage of the cohort having any type of barrier increased over the long-term intervention period. A majority of the weight loss barriers were significantly associated with younger age, greater obesity, and non-Caucasian race/ethnicity (p-values vary). Physical activity barriers, particularly thought and mood cues, social cues and time management, physical injury or illness and access/weather, were most significantly associated with being female and obese (p  90% long term) and regularly reviewed self-monitoring skills. More costly approaches were used infrequently during the first 16 sessions (≤10%) but increased over 3.2 years. Behavioral problem solving approaches have short and long term dissemination potential for many kinds of participant barriers. Given minimal resources, increased attention to training lifestyle coaches in the consistent use of these

    The relationship between poor health and unemployment is well established. Health promotion among unemployed persons may improve their health. The aims of this study were to investigate characteristics of non-participants and drop-outs in a multidisciplinary health promotion programme for long-term unemployed persons with health complaints, to evaluate changes in physical health among participants, and to investigate determinants of improvement in physical health. A longitudinal, non-controlled design was used. The programme consisted of two weekly exercise sessions and one weekly cognitive session during 12 weeks. The main outcome measures were body mass index, blood pressure, cardiorespiratory fitness, abdominal muscle strength, and low back and hamstring flexibility. Potential determinants of change in physical health were demographic variables, psychological variables (self-esteem, mastery, and kinesiophobia), and self-perceived health. The initial response was 73% and 252 persons had complete data collection at baseline. In total, 36 subjects were lost during follow-up. Participants were predominantly low educated, long-term unemployed, and in poor health. Participation in the programme was not influenced by demographic and psychological factors or by self-reported health. Drop-outs were younger and had a lower body mass index at baseline than subjects who completed the programme. At post-test, participants' cardiorespiratory fitness, abdominal muscle strength, and flexibility had increased by 6.8%-51.0%, whereas diastolic and systolic blood pressures had decreased by 2.2%-2.5%. The effect sizes ranges from 0.17-0.68. Participants with the poorest physical health benefited most from the programme and gender differences in improvement were observed. Physical health of unemployed persons with health complaints improved after participation in this health promotion programme, but not sufficiently, considering their poor physical health at baseline.

    Full Text Available This study investigated whether physical activity levels and other outcomes were maintained at 1-year from completion of a 2-year telerehabilitation intervention in COPD. During the post-intervention year, nine patients with COPD (FEV1 % of pred. 42.4±19.8%; age 58.1±6 years were encouraged to exercise on a treadmill at home and monitor daily symptoms and training sessions on a webpage as during the intervention. Participants were not provided supervision or motivational support. Physical activity levels decreased from 3,806 steps/day to 2,817 steps/day (p= 0.039. There was a decline in time spent on light physical activity (p=0.009, but not on moderate-to-vigorous activity (p=0.053. Adherence to registration of symptoms and training sessions decreased significantly. Other outcomes including health status, quality of life, anxiety and depression, self-efficacy, and healthcare utilization did not change significantly. In conclusion, provision of equipment for self-management and unsupervised home exercise might not be enough to maintain physical activity levels.

    The objective of this study was to analyze the effect of supplementation with creatine and glutamine on physical fitness of military police officers. Therefore, an experimental double blind study was developed, with the final sample composed by 32 men randomly distributed into three groups: a group supplemented with creatine (n=10), glutamine (n=10) and a placebo group (n=12) and evaluated in three distinct moments, in an interval of three months (T1, T2 and T3). The physical training had a weekly frequency of 5 sessions × 90 min, including strength exercises, local muscular resistance, flexibility and both aerobic and anaerobic capacity. After analyzing the effect of time, group and interaction (group × time) for measures that indicated the physical capabilities of the subjects, a significant effect of time for the entire variable was identified (p0,05). In face of the results it was concluded that supplementation with creatine and glutamine showed no ergogenic effect on physical performance in military police officers.

    Further research is needed to improve the evidence regarding determinants of physical activity (PA) as a crucial step to plan higher effective intervention strategies. The goal of the present study is to identify socio-demographic and clinical characteristics of primary care (PHC) insufficiently active patients that are associated with longitudinal changes in the level of physical activity. Longitudinal analysis of baseline socio-demographic and clinical predictors of physical activity change in insufficiently active PHC patients who participated in a PA-promoting multi-centre randomized clinical trial conducted from October 2003 through March 2006. The primary outcome measure was the self-reported physical activity assessed with the 7-day Physical Activity Recall (PAR), at baseline, 6, 12 and 24 months. Baseline covariates included sex, age, social class, anthropometric measures and other cardiovascular risk factors or associated diseases (Diabetes, HTA, tobacco use, etc.), and stage of readiness to change PA. Generalized linear mixed models were used to estimate longitudinal association of studied variables on PA change over the three follow-up measurements. A total of 3691 patients (85% of the 4317 recruited in the trial) with at least one follow-up measurement were included in the longitudinal analysis. At baseline, analysed patients (mean age: 50.6 years; 64.6% women) devoted 34.7 minutes and 2.36 metabolic equivalent hours per week (MET.h/week) to moderate and vigorous physical activity. Older age, male gender, higher social class, lower BMI, diagnosis of diabetes or hypertension, and measurement season were significant predictors of PA longitudinal change. The effect of baseline readiness to change on PA dose was modified by time, showing a positive gradient in favour of those with more readiness to change that increases significantly at 12 and 24 months (p-value interaction < .0001). Identified baseline characteristics such as readiness to change and

    Cross-sectional and retrospective studies have highlighted the long-term negative effects of maternal depression on offspring physical, social, and emotional development, but longitudinal research is needed to clarify the pathways by which maternal depression during pregnancy and early childhood affects offspring outcomes. The current study tested one developmental pathway by which maternal depression during pregnancy might negatively impact offspring mental health in young adulthood, via poor physical health in early childhood. The sample consisted of 815 Australian youth and their mothers who were followed for 20 years. Mothers reported on their own depressive symptoms during pregnancy and offspring early childhood. Youth completed interviews about health-related stress and social functioning at age 20 years, and completed a questionnaire about their own depressive symptoms 2 to 5 years later. Path analysis indicated that prenatal maternal depressive symptoms predicted worse physical health during early childhood for offspring, and this effect was partially explained by ongoing maternal depression in early childhood. Offspring poor physical health during childhood predicted increased health-related stress and poor social functioning at age 20. Finally, increased health-related stress and poor social functioning predicted increased levels of depressive symptoms later in young adulthood. Maternal depression had a significant total indirect effect on youth depression via early childhood health and its psychosocial consequences. Poor physical health in early childhood and its effects on young adults' social functioning and levels of health related stress is one important pathway by which maternal depression has long-term consequences for offspring mental health.

    To evaluate the relationship between long-term maintenance of moderate to vigorous physical activity (MVPA) and clinical outcomes in fibromyalgia (FM). Patients with FM (n = 170) received individualized exercise prescriptions and completed baseline and followup physical activity assessments using the Community Health Activities Model Program for Seniors questionnaire at weeks 12, 24, and 36. The primary outcome was the change in the Fibromyalgia Impact Questionnaire-Physical Impairment (FIQ-PI) score. The secondary outcomes included improvements in overall well-being (FIQ total score), pain severity ratings, and depression. Using a threshold increase in MVPA of ≥10 metabolic equivalent hours/week above usual activities, 27 subjects (15.9%) increased and sustained (SUS-PA), 68 (40%) increased but then declined (UNSUS-PA), and 75 (44.1%) did not achieve (LO-PA) this benchmark. Compared to LO-PA subjects, both SUS-PA and UNSUS-PA subjects reported greater improvement in FIQ-PI (P physical function and overall well-being in patients with FM. Although sustained physical activity was not associated with greater clinical benefit compared with unsustained physical activity, these findings also suggest that performing greater volumes of physical activity is not associated with worsening pain in FM. Future research is needed to determine the relationship between sustained MVPA participation and subsequent improvement in patient outcomes. Copyright © 2013 by the American College of Rheumatology.

    2018-02-01

    No longitudinal epidemiological research has reported associations between physical frailty and performance in specific cognitive domains. Our aim was to investigate whether such associations existed in the absence of accompanying neurodegenerative disorders such as mild cognitive impairment (MCI) and dementia. We addressed this issue in a population-based sample of 896 adults aged 70 years and older over 4 waves of data covering a 12-year period. Physical frailty was assessed and a cognitive battery included measures of processing speed, verbal fluency, face and word recognition, episodic memory and simple and choice reaction time (RT). Latent growth models showed frailty was associated with poorer baseline performance in processing speed, verbal fluency, simple and choice RT, and choice intraindividual RT variability. However, no significant effects of frailty on slopes of cognition were observed, suggesting that frailty was not associated with cognitive decline. Importantly, when the models took possible dementia into account, significant effects were retained suggesting that differences were not associated with dementia-related neurodegenerative disorders. The findings suggest that frailty-related cognitive deficits may exist independently of mechanisms underpinning neurodegenerative disorders such as MCI and dementia. If confirmed, this finding suggests a new avenue for preventative and therapeutic interventions in clinical and public health contexts for older adults. © The Author(s) 2018.

    2011-01-01

    The results of six months of continuous measurement of the indoor radon concentration levels in the building where the Physics Institute 3 MV Pelletron particle accelerator is located are presented. This study has three major objectives: a) to know the actual values of the levels of indoor radon in this installation, where personnel spend many hours and sometimes days; b) assess the radiological risk from radon inhalation for personnel working permanently in the laboratory, as well as incidental users; and c) establish, if necessary, time limits for continuous permanence on the location for indoor radon exposure. Passive nuclear track detectors and dynamic systems were employed, covering six months (August, 2009 to January, 2010). For the calculation of internal dose the Radon Individual Dose Calculator was used. The results indicate that the indoor radon levels are below the US EPA recommended levels (400 Bq/m 3 ) in workplaces. The measurements help to establish levels for workplaces in Mexico. (Author)

    Biosynthetic hydrogels can meet the drawbacks caused by natural and synthetic ones for biomedical applications. In the current article we present a novel biosynthetic alginate-poly(propylene fumarate) copolymer based chemically crosslinked hydrogel scaffolds for cardiac tissue engineering applications. Partially crosslinked PA hydrogel and fully cross linked PA-A hydrogel scaffolds were prepared. The influence of chemical and physical (morphology and architecture of hydrogel) characteristics on the long term cellular response was studied. Both these hydrogels were cytocompatible and showed no genotoxicity upon contact with fibroblast cells. Both PA and PA-A were able to resist deleterious effects of reactive oxygen species and sustain the viability of L929 cells. The hydrogel incubated oxidative stress induced cells were capable of maintaining the intra cellular reduced glutathione (GSH) expression to the normal level confirmed their protective effect. Relatively the PA hydrogel was found to be unstable in the cell culture medium. The PA-A hydrogel was able to withstand appreciable cyclic stretching. The cyclic stretching introduced complex macro and microarchitectural features with interconnected pores and more structured bound water which would provide long-term viability of around 250% after the 24th day of culture. All these qualities make PA-A hydrogel form a potent candidate for cardiac tissue engineering. © 2013 Wiley Periodicals, Inc.

    Sex, age, body mass index (BMI), perceived health and health behavior are correlates known to affect physical activity and sedentary time. However, studies have often been cross-sectional, and less is known about long-term correlates. Thus, the aims were to investigate 1) the associations between a set of characteristics (demographic, biological, psychological, and behavioral) and objectively measured physical activity and sedentary time at 13-year follow-up, and 2) the association between changes in these characteristics over time and physical activity and sedentary time. Baseline characteristics were collected in 40-year-olds in 1996, and follow-up data on objectively measured physical activity and sedentary time were obtained in 2009 (n = 240). Data were analyzed by multiple linear regressions. Self-reported physical activity (P physical activity (MVPA) whereas BMI (P = .034) and increased BMI (P = .014) were negatively associated with MVPA at follow-up. Women spent less time being sedentary than men (P = .019). Education (P < .001) was positively associated and improved perceived health (P = .010) was negatively associated with sedentary time at follow-up. MVPA and sedentary time at follow-up were associated with behavioral, biological and demographic correlates. However, the nature of our analyses prevents us from inferring causality.

    Findings on weight training and waist circumference (WC) change are controversial. This study examined prospectively whether weight training, moderate to vigorous aerobic activity (MVAA), and replacement of one activity for another were associated with favorable changes in WC and body weight (BW). Physical activity, WC, and BW were reported in 1996 and 2008 in a cohort of 10,500 healthy U.S. men in the Health Professionals Follow-up Study. Multiple linear regression models (partition/substitution) to assess these associations were used. After adjusting for potential confounders, a significant inverse dose-response relationship between weight training and WC change (P-trend weight training (-0.67 cm, 95% CI -0.93, -0.41) than for MVAA (-0.33 cm, 95% CI -0.40, -0.27), other activities (-0.16 cm, 95% CI -0.28, -0.03), or TV watching (0.08 cm, 95% CI 0.05, 0.12). Substituting 20 min/day of weight training for any other discretionary activity had the strongest inverse association with WC change. MVAA had the strongest inverse association with BW change (-0.23 kg, 95% CI -0.29, -0.17). Among various activities, weight training had the strongest association with less WC increase. Studies on frequency/volume of weight training and WC change are warranted. © 2014 The Obesity Society.

    Many different types of data were collected during SAFOD Phases 1 and 2 (2004-2005) as part of the National Science Foundation's EarthScope program as well as from the SAFOD Pilot Hole, drilled in 2002 and funded by the International Continental Drilling Program (ICDP). Both SAFOD and the SAFOD Pilot Hole are being conducted as a close collaboration between NSF, the U.S. Geological Survey and the ICDP. SAFOD data products include cuttings, core and fluid samples; borehole geophysical measurements; and strain, tilt, and seismic recordings from the multilevel SAFOD borehole monitoring instruments. As with all elements of EarthScope, these data (and samples) are openly available to members of the scientific and educational communities. This paper presents the acquisition, storage and distribution plan for SAFOD data products. Washed and unwashed drill cuttings and mud samples were collected during Phases 1 and 2, along with three spot cores at depths of 1.5, 2.5, and 3.1 km. A total of 52 side-wall cores were also collected in the open-hole interval between 2.5 and 3.1 km depth. The primary coring effort will occur during Phase 3 (2007), when we will continuously core up to four, 250-m-long multilaterals directly within and adjacent to the San Andreas Fault Zone. Drill cuttings, core, and fluid samples from all three Phases of SAFOD drilling are being curated under carefully controlled conditions at the Integrated Ocean Drilling Program (IODP) Gulf Coast Repository in College Station, Texas. Photos of all physical samples and a downloadable sample request form are available on the ICDP website (http://www.icdp-online.de/sites/sanandreas/index/index.html). A suite of downhole geophysical measurements was conducted during the first two Phases of SAFOD drilling, as well as during drilling of the SAFOD Pilot Hole. These data include density, resistivity, porosity, seismic and borehole image logs and are also available via the ICDP website. The SAFOD monitoring program

    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.

    To report long-term progression-free survival (PFS) and late-toxicity outcomes in pediatric craniopharyngioma patients treated with IMRT. Twenty-four children were treated with IMRT to a median dose of 50.4Gy (range, 49.8-54Gy). The clinical target volume (CTV) was the gross tumor volume (GTV) with a 1cm margin. The planning target volume (PTV) was the CTV with a 3-5mm margin. Median follow-up was 107.3months. The 5- and 10-year PFS rates were 65.8% and 60.7%. The 5- and 10-year cystic PFS rates were 70.2% and 65.2% while the 5- and 10-year solid PFS were the same at 90.7%. Endocrinopathy was seen in 42% at initial diagnosis and in 74% after surgical intervention, prior to IMRT. Hypothalamic dysfunction and visual deficits were associated with increasing PTV and number of surgical interventions. IMRT is a viable treatment option for pediatric craniopharyngioma. Despite the use of IMRT, majority of the craniopharyngioma patients experienced long-term toxicity, many of which present prior to radiotherapy. Limitations of retrospective analyses on small patient cohort elicit the need for a prospective multi-institutional study to determine the absolute benefit of IMRT in pediatric craniopharyngioma.

    Physical activity may be associated with decreasing endometrial cancer risk; it remains unclear whether the association is modified by body size. Among 93 888 eligible California Teachers Study participants, 976 were diagnosed with incident endometrial cancer between 1995-1996 and 2007. Cox proportional hazards regression methods were used to estimate relative risks (RRs) and 95% confidence intervals (CIs) for endometrial cancer associated with long-term (high school through age 54 years) and baseline (3 years prior to joining the cohort) strenuous and moderate recreational physical activity, overall and by body size. Increased baseline strenuous recreational physical activity was associated with decreased endometrial cancer risk (Ptrend=0.006) with approximately 25% lower risk among women exercising >3 h per week per year than among those exercising activity was associated with lower risk among overweight/obese women. Increasing physical activity, particularly strenuous activity, may be a lifestyle change that overweight and obese women can implement to reduce their endometrial cancer risk.

    Medical developments have allowed the management of patients aged over 70 years with severe abdominal pathologies requiring intensive care unit (ICU) admission. These patients require enhanced life support and present a high ICU mortality. We investigated the outcome and quality of life (QOL) of elderly patients 2 years after their ICU stay for abdominal pathologies. Patients aged 70 years or over with abdominal pathologies, admitted to our ICU over a period of 2 years, were included. Two years following their ICU stay, a letter informed the patients about the present study. Consent to participate was obtained by telephone. QOL was assessed by the Euro-QOL and Short Form-36 questionnaires. Other patient-centered outcomes were evaluated. Overall, 2780 patients were admitted to the ICU during the study period; 141 (5%) patients were eligible; 112 of the 141 (79%) survived their ICU stay, 95 (67%) survived their hospital stay and 52 (37%) were alive 2 years after their ICU stay; 36 of the 52 survivors (69%) answered the questionnaire. Their QOL 2 years after their ICU stay was decreased in comparison with an age-matched population. Eighty-one per cent of patients lived at home and 57% were totally independent. They perceived their ICU stay as positive and 75% stated that they would agree to go through intensive care again. Factors associated with 2-year survival were the absence of co-morbidity, absence of malignancy and a lower Simplified Acute Physiology II score on ICU admission. A high mortality rate and a decrease in QOL were observed in elderly patients with severe abdominal pathologies. Nonetheless, these patients were able to adapt well to their physical disabilities.

    Background/Context A period of non-surgical management is advocated prior to surgical treatment for most patients with lumbar spinal stenosis. Currently, little evidence is available to define optimal non-surgical management. Physical therapy is often used, however its use and effectiveness relative to other non-surgical strategies has not been adequately explored. Purpose Describe the utilization of physical therapy and other non-surgical interventions by patients with lumbar spinal stenosis and examine the relationship between physical therapy and long-term prognosis. Study Design Secondary analysis of the Spine Patient Outcomes Research Trial (SPORT) combining data from randomized and observational studies. Setting 13 spine clinics in 11 states in the United States. Patient Sample Patients with lumbar spinal stenosis receiving non-surgical management including those who did or did not receive physical therapy within 6 weeks of enrollment. Outcome Measures Primary outcome measures included cross-over to surgery, the bodily pain and physical function scales changes from the Survey Short Form 36 (SF-36), and the modified Oswestry Disability Index. Secondary outcome measures were patient satisfaction and the Sciatica Bothersomeness Index. Methods Baseline characteristics and rates of cross-over to surgery were compared between patients who did or did not receive physical therapy. Baseline factors predictive of receiving physical therapy were examined with logistic regression. Mixed effects models were used to compare outcomes between groups at 3 and 6 months, and 1 year after enrollment adjusted for baseline severity and patient characteristics. Results Physical therapy was used in the first 6 weeks by 90 of 244 patients (37%) and was predicted by the absence of radiating pain and being single instead of married. Physical therapy was associated with a reduced likelihood of cross-over to surgery after 1 year (21% vs 33%, p=0.045), and greater reductions on the SF-36

    To compare memories from the intensive care unit (ICU) and short- and long-term psychological morbidity in patients after sedation with intravenous midazolam or inhaled isoflurane. Prospective long-term follow-up after randomized controlled trial. General ICU at Karolinska University Hospital, Solna, Stockholm. Forty patients in need of sedation during ventilator treatment. Patients were randomized to receive isoflurane or midazolam for goal-directed sedation until extubation or for a maximum of 96 hrs. For short-term follow-up, doctors', nurses', and physiotherapists' notes from the 4 days following exposure to the study drugs were reviewed for words indicating adequate or pathologic cognitive and psychological recovery. For long-term follow-up, all 6-month survivors received questionnaires including the ICU Memory Tool (ICU-MT), Hospital Anxiety and Depression Scale (HADS), Impact of Event Scale (IES), and Well-Being Index. Additionally, several screening questions for previous posttraumatic stress symptoms were included. In the short term follow-up, no significant differences were found between groups. In the long-term follow-up, a trend toward fewer hallucinations/delusions after isoflurane sedation than after midazolam (two of ten isoflurane patients vs. five of seven midazolam patients) was found (p = .06). None of the five solely isoflurane-sedated patients reported hallucinations/delusions from the ICU. There was no difference in groups in long-term psychological morbidity as measured with HADS and IES. Memories of negative feelings in the ICU (ICU-MT) were associated with high HADS and IES scores (Fisher's exact test, p = .02 and p = .01, respectively). Sedation of ICU patients with isoflurane may result in fewer delusional memories or hallucinations from the ICU compared with more commonly used intravenous sedation. Memories of negative feelings from the ICU were associated with symptoms of depression or anxiety or symptoms indicating posttraumatic stress

    Methane (CH4) oxidation is the only known biological sink process for mitigating atmospheric and terrestrial emissions of CH4, a major greenhouse gas. Methane oxidation in an alluvial soil planted to rice (Oryza sativa L.) under long-term application of organic (compost with a C/N ratio of 21.71), and mineral fertilizers was measured in a field-cum-laboratory incubation study. Oxidation rates were quantified in terms of decrease in the concentration of CH4 in the headspace of incubation vessels and expressed as half-life (t(1)2) values. Methane oxidation rates significantly differed among the treatments and growth stages of the rice crop. Methane oxidation rates were high at the maximum tillering and maturity stages, whereas they were low at grain-filling stage. Methane oxidation was low (t(1)2) = 15.76 d) when provided with low concentration of CH4. On the contrary, high concentration of CH4 resulted in faster oxidation (t(1)2) = 6.67 d), suggesting the predominance of "low affinity oxidation" in rice fields. Methane oxidation was stimulated following the application of mineral fertilizers or compost implicating nutrient limitation as one of the factors affecting the process. Combined application of compost and mineral fertilizer, however, inhibited CH4 oxidation probably due to N immobilization by the added compost. The positive effect of mineral fertilizer on CH4 oxidation rate was evident only at high CH4 concentration (t(1)2 = 4.80 d), while at low CH4 concentration their was considerable suppression (t(1) = 17.60 d). Further research may reveal that long-term application of fertilizers, organic or inorganic, may not inhibit CH4 oxidation.

    Over the past decades, life-styles changing have led to exacerbated food and caloric intake and a reduction in energy expenditure. Obesity, main outcome of these changes, increases the risk for developing type 2 diabetes, cardiovascular disease and metabolic syndrome, the leading cause of death in adult and middle age population. Body weight and energy homeostasis are maintained via complex interactions between orexigenic and anorexigenic neuropeptides that take place predominantly in the hypothalamus. Overeating may disrupt the mechanisms of feeding control, by decreasing the expression of proopiomelanocortin (POMC) and α-melanocyte stimulating hormone (α-MSH) and increasing orexigenic neuropeptide Y (NPY) and agouti-related peptide (AgRP), which leads to a disturbance in appetite control and energy balance. Studies have shown that regular physical exercise might decrease body-weight, food intake and improve the metabolic profile, however until the currently there is no consensus about its effects on the expression of orexigenic/anorexigenic neuropeptides expression. Therefore, we propose that the type and length of physical exercise affect POMC/αMSH and NPY/AgRP systems differently and plays an important role in feeding behavior. Moreover, based on the present reports, we hypothesize that increased POMC/αMSH overcome NPY/AgRP expression decreasing food intake in long term physical exercise and that results in amelioration of several conditions related to overweight and obesity.

    ᅟ: Chronic inactivity and weight regain are serious health concerns following bariatric surgery. Neighborhood walkability is associated with higher physical activity and lower obesity rates in normal weight populations. Explore the influence of neighborhood walkability on physical activity and sedentarism among long-term post-bariatric surgery patients. Fifty-eight adults aged 50.5 ± 9.1 years, with a BMI of 34.6 ± 9.7 kg/m 2 having undergone surgery 9.8 ± 3.15 years earlier participated in this study. Participants were asked to wear an ActivPAL™ tri-axial accelerometer attached to their mid-thigh for 7-consecutive days, 24 hours/day. The sample was separated into those that live in Car-Dependent (n = 23), Somewhat Walkable (n = 14), Very Walkable (n = 16), and Walker's Paradise (n = 5) neighborhoods as defined using Walk Score®. ANCOVA was performed comparing Walk Score® categories on steps and sedentary time controlling for age and sex. Neighborhood walkability did not influence either daily steps (F (3, 54) = 0.921, p = 0.437) or sedentary time (F (3, 54) = 0.465, p = 0.708), Car-Dependent (6359 ± 2712 steps, 9.54 ± 2.46 hrs), Somewhat Walkable (6563 ± 2989 steps, 9.07 ± 2.70 hrs), Very Walkable (5261 ± 2255 steps, 9.97 ± 2.06 hrs), and Walker's Paradise (6901 ± 1877 steps, 10.14 ± 0.815 hrs). Walkability does not appear to affect sedentary time or physical activity long-term post-surgery. As the built-environment does not seem to influence activity, sedentarism, or obesity as it does with a normal weight population, work needs to be done to tailor physical activity programming after bariatric surgery.

    Purpose: To evaluate long-term health-related quality of life (HRQOL) in 2 prospective studies of chemo–intensity modulated radiation therapy (chemo-IMRT) for oropharyngeal cancer (OPC). Methods and Materials: Of 93 patients with stage III/IV OPC treated on prospective studies of swallowing and salivary organ-sparing chemo-IMRT, 69 were eligible for long-term HRQOL assessment. Three validated patient-reported instruments, the Head and Neck QOL (HNQOL) questionnaire, the University of Washington quality of life (UWQOL) questionnaire, and the Xerostomia Questionnaire (XQ), previously administered from baseline through 2 years in the parent studies, were readministered at long-term follow-up, along with the Short-Form 36. Long-term changes in HRQOL from before treatment and 2 years were evaluated. Results: Forty patients (58%) with a median follow-up of 6.5 years participated, 39 of whom (97.5%) had confirmed human papillomavirus–positive OPC. Long term, no clinically significant worsening was detected in mean HRQOL scores compared with 2 years, with stable or improved HRQOL from before treatment in nearly all domains. “Moderate” or greater severity problems were uncommon, reported by 5% of patients for eating, 5% for swallowing, and 2.5% and 5% by HNQOL and UWQOL summary scores, respectively. Freedom from percutaneous endoscopic gastrostomy tube dependence and stricture dilation beyond 2 years was 97.5% and 95%, respectively. Eleven percent and 14% of patients reported “moderate” or “severe” long-term worsening in HNQOL Pain and Overall Bother domains, respectively, which were associated with mean dose to the cervical esophagus, larynx, and pharyngeal constrictors. Conclusions: At more than 6 years' median follow-up, OPC patients treated with swallowing and salivary organ-sparing chemo-IMRT reported stable or improved HRQOL in nearly all domains compared with both before treatment and 2-year follow-up. New late toxicity after 2 years was

    In specialized pain clinics there is an increasing number of patients with severe chronic noncancer pain (CNCP) despite long-term opioid medication. Few clinical studies show short-term pain relief after opioid withdrawal (OW). We have evaluated the relation between pain intensity after OW and long-term opioid nonuse. One hundred two consecutive patients with severe CNCP despite opioid medication (mean treatment duration, 43 mo) reported pain intensity (numerical rating scale, 0 to 10), Pain Disability Index, mood (CES-D), and quality of life (Short Form 36) before, shortly, and 12 to 24 months after inpatient OW. Total opioid withdrawal (n = 78) or significant dose reduction (DR; n = 24, mean reduction, 82%) was performed after individual decision. Opioid intake 12 to 24 months later, respectively dose increase ≥ 100% (DR group), was considered relapse. T tests, multivariable analysis of variance, logistic regression. After OW current pain intensity significantly decreased on an average by 41% (6.4 ± 2.4 vs. 3.8 ± 2.5), maximal and average pain by 18% and 24%, respectively. Twelve to 24 months later 42 patients (41%) relapsed (31 of the total opioid withdrawal group, 6 of the DR group, 5 lost). Patients without later relapse showed significantly lower pain scores than the later relapsed patients already shortly after OW (5.0 ± 2.2 vs. 5.9 ± 2.1) and 12 to 24 months later (5.5 ± 2.4 vs. 6.5 ± 2.0). There was a significant relation between relapse probability and pain intensity immediately after OW. In many patients with severe CNCP, despite opioid medication, sustainable pain relief can be achieved if OW is included in the rehabilitation program. Consequently, we recommend OW for opioid-resistant CNCP before any opioid escalation. Lower pain intensity shortly after OW may predict the long-term opioid nonuse probability.

    Information regarding factors that hinder or stimulate older adults in long-term care facilities (LTCF) for being physically active is available in the literature, but much less is known regarding perceived motivators and barriers among physiotherapists (PTs) to organize physical activity (PA) in LTCF. The main purpose of this study was to examine factors influencing PTs to organize PA in LTCF for older adults. A secondary goal was to examine the PTs' knowledge about and their barriers at the PA guidelines for older adults of the World Health Organization (WHO). A mixed qualitative and quantitative study was carried out using semistructured interviews (n = 24) followed by an online survey (n = 254). As a frame the social-ecological model (McLeroy) was used, distinguishing factors at the intrapersonal, interpersonal, and community level. In the qualitative component the PTs reported 41 motivators and 35 barriers for organizing PA in LTCF. The survey revealed that although the majority of the respondents (71%) are convinced of the usefulness of PA in LTCF, 84% are not familiar with the WHO-guidelines. Seventy-five percent of the respondents believe that the WHO-guidelines are not feasible for LTCF-residents. The strongest motivators on the intrapersonal level were maintaining the independence of the residents (98%), reducing the risk of falling (98%), and improving the physical (93%) and psychological (90%) wellbeing of LTCF-residents. The social interaction among LTCF-residents (91%) during PA was the strongest motivator on the interpersonal level. Motivators on the community level are the belief that PA is the basis of their physiotherapeutic work (89%) and that offering varied activities avoids PA becoming monotonous (71%).

    It is known from previous research that physical exercise prevents long-term memory deficits induced by maternal deprivation in rats. But we could not assume similar effects of physical exercise on short-term memory, as short- and long-term memories are known to result from some different memory consolidation processes. Here we demonstrated that, in addition to long-term memory deficit, the short-term memory deficit resultant from maternal deprivation in object recognition and aversive memory tasks is also prevented by physical exercise. Additionally, one of the mechanisms by which the physical exercise influences the memory processes involves its effects attenuating the oxidative damage in the maternal deprived rats' hippocampus and prefrontal cortex.

    The appropriate management of radioactive waste arising from the nuclear fuel cycle is considered to be a key issue in the development of future, more sustainable nuclear energy systems. In this context, the partitioning and transmutation of actinides could play an important role through the achievement of very significant reductions in the actinide content and radiotoxicity of the high-level waste requiring geological disposal. The current paper reports on the results of a detailed physics study carried out to compare the pros and cons of alternative strategies for closure of the nuclear fuel cycle. Different long-term 'steady-state' scenarios have been considered, involving the deployment, to varying degrees, of light water reactors (LWRs) and advanced fast-spectrum systems. The same nuclear data and calculation methods have been used throughout, so that a consistent and reliable comparison of the relative performance of the three basic fuel cycle options (once-through, plutonium recycle, and recycling of all actinides) has been made possible. In addition, with transmutation having been considered employing both critical and accelerator-driven fast-spectrum systems, the study has provided an evaluation of the advantages and disadvantages of these two different advanced system types

  3. Men still value physical attractiveness in a long-term mate more than women: rejoinder to Eastwick, Neff, Finkel, Luchies, and Hunt (2014).

    Sexual selection theory and parental investment theory suggest that partner physical attractiveness should more strongly affect men's relationship outcomes than women's relationship outcomes. Nevertheless, the contextual nature of this prediction makes serious methodological demands on studies designed to evaluate it. Given these theories suggest that men value observable aspects of partner attractiveness more than women do only in the context of long-term and reproductively viable relationships, they require that studies testing this sex difference involve (a) participants in long-term relationships, (b) women of child-bearing age, and (c) measures of physical attractiveness that assess observable aspects of appearance. In our original article (Meltzer, McNulty, Jackson, & Karney, 2014), we applied 7 methodological standards that allowed us to meet these 3 criteria and demonstrated that partner physical attractiveness is more strongly associated with men's long-term relationship satisfaction than women's long-term relationship satisfaction. Eastwick, Neff, Finkel, Luchies, and Hunt (2014), in contrast, described an unfocused meta-analysis, a refocused meta-analysis, and new data that all failed to meet these criteria and, not surprisingly, failed to demonstrate such a sex difference. We continue to believe that men value physical attractiveness more than women do, that such preferences have implications for their evaluations of long-term relationships, and that studies properly calibrated to detect such differences will do so.

  6. Short and long term ionizing radiation effects on charge-coupled devices in radiation environment of high-intensity heavy ion accelerators

    Radiation effects on semiconductor devices is a topical issue for high-intensity accelerator projects. In particular it concerns Charge-Coupled Device (CCD) cameras, which are widely used for beam profile monitoring and surveillance in high radiation environment. One should have a clear idea of short and long term radiation effects on such devices. To study these effects, a CCD camera was placed in positions less than half meter away from beam loss point. Primary heavy ion beam of 0.95GeV/n Uranium was dumped into a thick aluminium target creating high fluences of secondary particles (e.g., gammas, neutrons, protons). Effects of these particles on CCD camera were scored with LabView based acquisition software. Monte Carlo calculations with FLUKA code were performed to obtain fluence distributions for different particles and make relevant comparisons. Long term total ionising dose effects are represented by dark current increase, which was scored throughout experiment. Instant radiation effects are represented by creation of charge in CCD cells by ionising particles. Relation of this charge to beam intensity was obtained for different camera positions and fluences within 5 orders of magnitude ranges. With high intensities this charge is so high that it may dramatically influence data obtained from CCD camera used in high radiation environment. The linearity of described above relation confirms linear response of CCD to ionizing radiation. It gives an opportunity to find a new application to CCD cameras as beam loss monitors (BLM).

    Full Text Available Abstract Background Recruiting and retaining health professions remains a high priority for health system planners. Different employment sectors may vary in their appeal to providers. We used the concepts of inflow and stickiness to assess the relative attractiveness of sectors for physical therapists (PTs in Ontario, Canada. Inflow was defined as the percentage of PTs working in a sector who were not there the previous year. Stickiness was defined as the transition probability that a physical therapist will remain in a given employment sector year-to-year. Methods A longitudinal dataset of registered PTs in Ontario (1999-2007 was created, and primary employment sector was categorized as ‘hospital’, ‘community’, ‘long term care’ (LTC or ‘other.’ Inflow and stickiness values were then calculated for each sector, and trends were analyzed. Results There were 5003 PTs in 1999, which grew to 6064 by 2007, representing a 21.2% absolute growth. Inflow grew across all sectors, but the LTC sector had the highest inflow of 32.0%. PTs practicing in hospitals had the highest stickiness, with 87.4% of those who worked in this sector remaining year-to-year. The community and other employment sectors had stickiness values of 78.2% and 86.8% respectively, while the LTC sector had the lowest stickiness of 73.4%. Conclusion Among all employment sectors, LTC had highest inflow but lowest stickiness. Given expected increases in demand for services, understanding provider transitional probabilities and employment preferences may provide a useful policy and planning tool in developing a sustainable health human resource base across all employment sectors.

    From 1899 to 2002, sandy Luvisol in the Paris region has been intensively irrigated with raw wastewater, resulting in major soil pollution by metallic trace elements (MTE). To identify the soil phases implicated in retaining these metals, sequential extractions were performed on a solum irrigated with untreated wastewater and another reference solum. The endogenous and exogenous fractions of MTE in the contaminated soil were discriminated using correlations between MTE and major elements defined from unpolluted soils of the area. In the contaminated soil no exogenous lead and chromium are present below the surface horizon, whereas exogenous zinc and copper are found down to the base of the solum. The endogenous MTE are mainly found in the residual fraction. Exogenous MTE appear to be associated with organic matter in the surface horizon, and exogenous zinc seems to be readsorbed on iron and manganese oxyhydroxides in the underlying horizons. - After 100 years of intensive irrigation with wastewater, no exogenous Pb and Cr are found in the subsoil, while exogenous Zn and Cu are found down to the base of the solum, mostly readsorbed

    To identify the direct and indirect effects of nutritional status, physical function, and cognitive function on activities of daily living in Japanese older adults requiring long-term care. In total, 179 participants aged ≥ 65 years who were eligible for long-term care insurance (mean age 85.5 ± 7.8 years) were recruited for this study. Nutritional status (Mini Nutritional Assessment, Short Form) and physical function (Short Physical Performance Battery) were examined. Activities of daily living, cognitive function and frailty were assessed using the Barthel Index, Mini-Mental State Examination and Clinical Frailty Scale, respectively. Path analysis was used to determine relationships between these factors and the activities of daily living. For Japanese older adults requiring long-term care, pathways were modeled for nutritional status, physical function and the activities of daily living. The total effect of nutritional status was 0.516 (Pphysical function on the activities of daily living was 0.458 (Pphysical function in aged Japanese people requiring long-term care. These findings suggest that maintaining good nutritional status and nutritional support might delay physical function decline, and prolong the activities of daily living. © 2013 Japan Geriatrics Society.

    Children in a German region took part in regular toothbrushing with fluoride gel during their time in primary school after having received a preventive program in kindergarten. The study aimed at determining the dental health of the students as a function of prevention in kindergarten and at school while taking into account their socioeconomic status and other confounders. The subjects were in six groups: groups 1 and 2, intensive prevention in kindergarten with and without fluoride gel at school; groups 3 and 4, basic prevention in kindergarten with and without fluoride gel at school; groups 5 and 6, no organized prevention in kindergarten with and without fluoride gel at school. Two dental examinations were performed for assessing caries experience and calculating caries increment from second grade (7-year-olds) to fourth grade (9-year-olds). A standardized questionnaire was used to record independent variables. To compare caries scores and preventive measures of various subgroups, non-parametric tests and a binary logistic regression analysis were performed. A significant difference was found in the mean decayed, missing, and filled tooth/teeth (DMFT) depending on socioeconomic status (no prevention in kindergarten, fluoride gel at school in children with low SES: DMFT = 0.47 vs. DMFT = 0.18 in children with high SES; p = 0.023). Class-specific differences were no longer visible among children who had taken part in an intensive preventive program combining daily supervised toothbrushing in kindergarten and application of fluoride gel in school. Early prevention, focusing on professionally supported training of toothbrushing in kindergarten and at school, has a positive effect on dental health and is able to reduce class-specific differences in caries distribution. Early training of toothbrushing and fissure sealing of first permanent molars are the most important factors for the dental health of primary school children.

    The aim of this study was to study the impact of a combined long-term lifestyle and high-intensity interval training intervention on body composition, cardiometabolic risk, and exercise tolerance in overweight and obese subjects. Sixty-two overweight and obese subjects (53.3 ± 9.7 yrs; mean body mass index, 35.8 ± 5 kg/m(2)) were retrospectively identified at their entry into a 9-mo program consisting of individualized nutritional counselling, optimized high-intensity interval exercise, and resistance training two to three times a week. Anthropometric measurements, cardiometabolic risk factors, and exercise tolerance were measured at baseline and program completion. Adherence rate was 97%, and no adverse events occurred with high-intensity interval exercise training. Exercise training was associated with a weekly energy expenditure of 1582 ± 284 kcal. Clinically and statistically significant improvements were observed for body mass (-5.3 ± 5.2 kg), body mass index (-1.9 ± 1.9 kg/m(2)), waist circumference (-5.8 ± 5.4 cm), and maximal exercise capacity (+1.26 ± 0.84 metabolic equivalents) (P high-density lipoprotein ratio were also significantly improved (P body mass and waist circumference loss were baseline body mass index and resting metabolic rate; those for body mass index decrease were baseline waist circumference and triglyceride/high-density lipoprotein cholesterol ratio. A long-term lifestyle intervention with optimized high-intensity interval exercise improves body composition, cardiometabolic risk, and exercise tolerance in obese subjects. This intervention seems safe, efficient, and well tolerated and could improve adherence to exercise training in this population.

    NG is an architect who suffered a left occipital-parietal hemorrhage cerebral vascular accident (CVA) in 2000, resulting in aphasia of Wernicke and conduction types. He was characterized with fluent paraphasic speech, decreased repetition, and impaired object naming. Comprehension was relatively preserved but reading and writing were severely compromised, as well as his auditory working memory. Despite a grim prognosis he underwent intensive aphasia therapy, lasting from 2001 to 2010, at the Center for Cognitive Rehabilitation of the Brain Injured at the Feuerstein Institute. The tailored-made interventions, applied in NG's therapy, were based upon the implementation of the principles of the Structural Mediated Learning Experience (MLE) and the Feuerstein Instrumental Enrichment (FIE) Program, to optimize his rehabilitation. As a result NG improved in most of his impaired linguistic capacities, attested by the results of neuropsychological and linguistic assessments performed throughout the years. More importantly, he was able to manage again his daily functions at a high level, and to resume his occupational role as an architect, a role which he holds to this day.

    Human beings are constantly exposed to many kinds of environmental agents which affect their health and lifespan. Galactic cosmic rays (GCRs) are the main source of ionizing radiation in the lower troposphere, in which secondary products can penetrate the ground and underground layers. GCRs affect the physical-chemical properties of the terrestrial atmosphere, as well as the biosphere. GCRs are modulated by solar activity and latitudinal geomagnetic field distribution. In our ecological/populational retrospective study, we analyzed the correlation between the annual flux of local secondary GCR-induced ionization (CRII) and mortality rates in the city of Sao Paulo, Brazil, between 1951-2012. The multivariate linear regression analyses adjusted by demographic and weather parameters showed that CRII are significantly correlated with total mortality, infectious disease mortality, maternal mortality, and perinatal mortality rates (p < 0.001). The underlying mechanisms are still unclear. Further cross-sectional and experimental cohort studies are necessary to understand the biophysical mechanisms of the association found here.

    Quantitatively ascertaining and analyzing long-term responses of crop yield and nitrate leaching on varying irrigation and fertilization treatments are focal points for guaranteeing crop yield and reducing nitrogen loss. The calibrated agricultural-hydrological RZWQM2 model was used to explore the long-term (2003-2013) transport processes of water and nitrogen and the nitrate leaching amount into groundwater in summer maize and winter wheat rotation field in typical intensive plant area in the North China Plain, Daxing district of Beijing. Simulation results showed that application rates of irrigation and nitrogen fertilizer have couple effects on crop yields and nitrogen leaching of root zone. When both the irrigation and fertilizer for summer maize and winter wheat were 400mm and 400kgNha -1 , respectively, nitrate leaching into groundwater accounted for 47.9% of application amount of nitrogen fertilizer. When application amount of irrigation is 200mm and fertilization is 200kgNha -1 , NUPE (nitrogen uptake efficiency), NUE (nitrogen use efficiency), NPFP (nitrogen partial factor productivity), and W pi (irrigation water productive efficiency) were in general higher than that under other irrigation and fertilization condition (irrigation from 104-400mm, fertilizer 104-400kgNha -1 ). Irrigation bigger than 200mm could shorten the response time of nitrate leaching in deeper soil layer in different irrigation treatment. Copyright © 2017 Elsevier B.V. All rights reserved.

    Trauma centers successfully save lives of severely injured patients who would have formerly died. However, survivors often have multiple complications and morbidities associated with prolonged intensive care unit (ICU) stays. Because the reintegration of patients into the society to lead an active and a productive life is the ultimate goal of trauma center care, we questioned whether our "success" may condemn these patients to a fate worse than death? Charts on all patients > or =18 years with ICU stay > or =10 days, discharged alive between June 1, 2002, and May 31, 2005, were reviewed. Patients with complete spinal cord injuries were excluded. Demographics, Injury Severity Score (ISS), presence of severe traumatic brain injury (TBI; Head Abbreviated Injury Scale [AIS] score = 4 or 5), presence of extremity fractures, need for operative procedures, ventilator days, complications, and discharge disposition were collected. Glasgow Outcome Scale score was calculated on discharge. Patients were contacted by phone to determine general health, work status, and using this data, Glasgow Outcome Scale score and a modified Functional Independence Measure (FIM) score were calculated. Two hundred and forty-one patients met inclusion criteria. Thirty-three patients died postdischarge from the hospital and 39 were known to be alive from the electronic medical records but were unable to be contacted. Sixty-nine patients could not be tracked down and were ultimately considered as lost to follow-up. The remaining 100 patients who were successfully contacted participated in the study. Eighty-one percent were men with a mean age of 42 years, mean and median ISS of 28. Severe TBI was present in 50 (50%) patients. Mean and median follow-up was 3.3 years from discharge. At the time of follow-up, 92 (92%) patients were living at home, 5 in nursing homes, and 3 in assisted living, a shelter, or halfway house. FIM scores ranged from 6 to 12 with 55% reached a maximal FIM score of 12. One

    Objectives This audit aims to evaluate the effectiveness of delivering an equivalent primary care service to a long-term forensic psychiatric inpatient population, using the UK primary care national Quality and Outcomes Framework (QOF).Method The audit compares the targets met by the general practitioner with special interest (GPwSI) service, using local and national QOF benchmarks (2005-2006), and determines the prevalence of chronic disease in a long-term inpatient forensic psychiatry population.Results The audit results show that the UK national QOF is a useful tool for assessment and evaluation of physical healthcare needs in a non-community based population. It shows an increased prevalence of all QOF-assessed long-term physical conditions when compared to the local East London population and national UK population, confirming previously reported elevated levels of physical healthcare need in psychiatric populations.Conclusions This audit shows that the UK General Practice QOF can be used as a standardised instrument for commissioning and monitoring the delivery of physical health services to in-patient psychiatric populations, and for the evaluation of the effectiveness of clinical interventions in long-term physical conditions. The audit also demonstrates the effectiveness of using a GPwSI in healthcare delivery in non-community based settings. We suggest that the findings may be generalisable to other long-term inpatient psychiatric and prison populations in order to further the objective of delivering an equivalent primary care service to all populations.The QOF is a set of national primary care audit standards and is freely available on the British Medical Association website or the UK Department of Health website. We suggest that primary care workers in health economies who have not yet developed their own national primary care standards can access and adapt these standards in order to improve the clinical standards of care given to the primary care

    Within the long-term pedagogical research ongoing since the school year 2008/2009 to 2015/2016 at the secondary vocational school in Bohumín was through of Entrance test of physics, which included curriculum of the sixth to ninth year of elementary school, regularly finding out, in which parts of Entrance test - Unit conversions, International System of Units, Properties of matter, Mechanics, Thermodynamics, Electricity and Magnetism, Optics, Atoms and Universe - pupils of the 1st years of secondary vocational school, technical and non-technical, reach a higher number of correct answers, in which dominates the wrong answers and which parts of the test pupils are better left out completely. It turned out that the results of these tests are very informative not only for theoretical and practical teaching, but also technical and other science subjects. The results of the Entrance tests are also a valuable source of information for continuous innovation Workbook of Physics - Mechanics for the 1st year of secondary vocational schools [1] - whose the first version began during the school year 2007/2008 and which was tested within pre-research in school years 2008/2009, 2009/2010 and within research in school year 2010/2011. On the basis of feedbacks getting from research the Workbook is regularly expanded, innovated and updated. The Workbook consists of parts dedicated to physical concepts, physical tasks, proposals to physical experiments, pupils comments from viewed video projection and documentary films, examples from the world of science and technology, examples from practice and real life, physical terminology in English, quizzes, competitions, interesting things and links related to discussed curriculum. The Workbook is divided into thematic sections, chapters and subchapters similar as physics textbooks for pupils of the 1st years of Secondary Schools in the Czech Republic. In the Workbook there are included tasks on fill in the words, polynomial tasks with

    The purpose of the study was to investigate the effects of short and long term High-Intensity Interval Training (HIIT) on anaerobic and aerobic performance, creatinine, uric acid, urea, creatine kinase, lactate dehydrogenase, catalase, superoxide dismutase, testosterone, corticosterone, and glycogen concentration (liver, soleus, and gastrocnemius). The Wistar rats were separated in two groups: HIIT and sedentary/control (CT). The lactate minimum (LM) was used to evaluate the aerobic and anaerobic performance (AP) (baseline, 6, and 12 weeks). The lactate peak determination consisted of two swim bouts at 13% of body weight (bw): (1) 30 s of effort; (2) 30 s of passive recovery; (3) exercise until exhaustion (AP). Tethered loads equivalent to 3.5, 4.0, 4.5, 5.0, 5.5, and 6.5% bw were performed in incremental phase. The aerobic capacity in HIIT group increased after 12 weeks (5.2 ± 0.2% bw) in relation to baseline (4.4 ± 0.2% bw), but not after 6 weeks (4.5 ± 0.3% bw). The exhaustion time in HIIT group showed higher values than CT after 6 (HIIT = 58 ± 5 s; CT = 40 ± 7 s) and 12 weeks (HIIT = 62 ± 7 s; CT = 49 ± 3 s). Glycogen (mg/100 mg) increased in gastrocnemius for HIIT group after 6 weeks (0.757 ± 0.076) and 12 weeks (1.014 ± 0.157) in comparison to baseline (0.358 ± 0.024). In soleus, the HIIT increased glycogen after 6 weeks (0.738 ± 0.057) and 12 weeks (0.709 ± 0.085) in comparison to baseline (0.417 ± 0.035). The glycogen in liver increased after HIIT 12 weeks (4.079 ± 0.319) in relation to baseline (2.400 ± 0.416). The corticosterone (ng/mL) in HIIT increased after 6 weeks (529.0 ± 30.5) and reduced after 12 weeks (153.6 ± 14.5) in comparison to baseline (370.0 ± 18.3). In conclusion, long term HIIT enhanced the aerobic capacity, but short term was not enough to cause aerobic adaptations. The anaerobic performance increased in HIIT short and long term compared with CT, without differences between HIIT short and long term. Furthermore, the

    The use of isotope tracers as a tool for assessing aquifer responses to intensive exploitation is demonstrated and used to attain a better understanding of the sustainability of intensively exploited aquifers in the North China Plain. Eleven well sites were selected that have long-term (years 1985-2014) analysis data of isotopic tracers. The stable isotopes δ18O and δ2H and hydrochemistry were used to understand the hydrodynamic responses of the aquifer system, including unconfined and confined aquifers, to groundwater abstraction. The time series data of 14C activity were also used to assess groundwater age, thereby contributing to an understanding of groundwater sustainability and aquifer depletion. Enrichment of the heavy oxygen isotope (18O) and elevated concentrations of chloride, sulfate, and nitrate were found in groundwater abstracted from the unconfined aquifer, which suggests that intensive exploitation might induce the potential for aquifer contamination. The time series data of 14C activity showed an increase of groundwater age with exploitation of the confined parts of the aquifer system, which indicates that a larger fraction of old water has been exploited over time, and that the groundwater from the deep aquifer has been mined. The current water demand exceeds the sustainable production capabilities of the aquifer system in the North China Plain. Some measures must be taken to ensure major cuts in groundwater withdrawals from the aquifers after a long period of depletion.

    Full Text Available Abstract Background The objective of the present study was to evaluate the short- and long-term intervention and mediation effects of a 3-month individualized need-supportive physical activity (PA counseling intervention on employees’ PA and sedentary behavior. Methods Insufficiently active employees (n = 300; mean age 42 ± 9 years; 78% female were recruited from a large pharmaceutical company in Flanders, Belgium. A quasi-experimental design was used in which the intervention group (N = 246 was recruited separately from the reference group (N = 54. Intervention group participants received a 3-month behavioral support intervention, which consisted of two one-hour face-to-face counseling sessions and three follow-up counseling contacts by e-mail or telephone at weeks three, six and nine. PA counseling, delivered by qualified PA counselors, aimed to satisfy participants’ basic psychological needs for autonomy, competence, and relatedness. Reference group participants did not receive individualized PA counseling. Outcome measures included objectively assessed and self-reported PA and sedentary time and psychological need satisfaction. Assessments were held at baseline, immediately after the intervention (short-term and 6 months post-intervention (long-term. Mixed model analyses and bootstrapping analyses were used to determine intervention and mediation effects, respectively. Results The intervention group increased weekday daily steps both in the short- and long-term, while the reference group showed reductions in daily step count (ES = .65 and ES = .48 in the short- and long-term, respectively. In the short-term, weekday moderate-to-vigorous PA increased more pronouncedly in the intervention group compared to the reference group (ES = .34. Moreover, the intervention group demonstrated reductions in self-reported sitting time during weekends both in the short- and long-term, whereas the reference group reported

    Patients with acute coronary syndromes (ACS) display diffuse coronary atheroma instability and heightened risk of early and late recurrent coronary events. We compared the long-term antiatherosclerotic efficacy of high-intensity statins in patients with ACS when compared with stable disease. Study of Coronary Atheroma by Intravascular Ultrasound: Effect of Rosuvastatin Versus Atorvastatin (SATURN) used serial intravascular ultrasound measures of coronary atheroma volume in patients treated with rosuvastatin 40 mg or atorvastatin 80 mg for 24 months. The overall effect of high-intensity statins on the change in coronary percent atheroma volume and major adverse cardiovascular events (death/nonfatal myocardial infarction/coronary revascularization) were evaluated in this post hoc analysis. When compared with non-ACS patients (n=678), patients with ACS (n=361) were younger, actively smoking, and have had a previous myocardial infarction (all P<0.001). At baseline, patients with ACS exhibited lower high-density lipoprotein cholesterol (43.5±11 versus 45.8±11 mg/dL; P=0.002), a higher apolipoprotein B: apolipoprotein A-1 ratio (0.90±0.24 versus 0.83±0.24; P<0.001) and greater percent atheroma volume (37.3±8.5% versus 35.9±8.1%; P=0.01) when compared with non-ACS patients. Despite similar achieved levels of lipid and inflammatory markers after high-intensity statin therapy, patients with ACS demonstrated greater percent atheroma volume regression than non-ACS patients (-1.46±0.14 versus -0.89±0.13; P=0.003). After propensity-weighted multivariable adjustment, baseline percent atheroma volume (P<0.001) and an ACS clinical presentation (P=0.02) independently associated with plaque regression. The 24-month major adverse cardiovascular events-free survival was similar between patients with ACS and non-ACS (90.6 versus 92.9%; P=0.25). Long-term high-intensity statin therapy caused greater plaque regression and comparable major adverse cardiovascular events rates in

  2. Long-Term Mild, rather than Intense, Exercise Enhances Adult Hippocampal Neurogenesis and Greatly Changes the Transcriptomic Profile of the Hippocampus.

    Full Text Available Our six-week treadmill running training (forced exercise model has revealed that mild exercise (ME with an intensity below the lactate threshold (LT is sufficient to enhance spatial memory, while intense exercise (IE above the LT negates such benefits. To help understand the unrevealed neuronal and signaling/molecular mechanisms of the intensity-dependent cognitive change, in this rat model, we here investigated plasma corticosterone concentration as a marker of stress, adult hippocampal neurogenesis (AHN as a potential contributor to this ME-induced spatial memory, and comprehensively delineated the hippocampal transcriptomic profile using a whole-genome DNA microarray analysis approach through comparison with IE. Results showed that only IE had the higher corticosterone concentration than control, and that the less intense exercise (ME is better suited to improve AHN, especially in regards to the survival and maturation of newborn neurons. DNA microarray analysis using a 4 × 44 K Agilent chip revealed that ME regulated more genes than did IE (ME: 604 genes, IE: 415 genes, and only 41 genes were modified with both exercise intensities. The identified molecular components did not comprise well-known factors related to exercise-induced AHN, such as brain-derived neurotrophic factor. Rather, network analysis of the data using Ingenuity Pathway Analysis algorithms revealed that the ME-influenced genes were principally related to lipid metabolism, protein synthesis and inflammatory response, which are recognized as associated with AHN. In contrast, IE-influenced genes linked to excessive inflammatory immune response, which is a negative regulator of hippocampal neuroadaptation, were identified. Collectively, these results in a treadmill running model demonstrate that long-term ME, but not of IE, with minimizing running stress, has beneficial effects on increasing AHN, and provides an ME-specific gene inventory containing some potential regulators

    Dose-escalated (DE) radiotherapy in the setting of localized prostate cancer has been shown to improve biochemical disease-free survival (bDFS) in several studies. In the same group of patients, androgen deprivation therapy (ADT) has been shown to confer a survival benefit when combined with radiotherapy doses of up to 70 Gy; however, there is currently little long-term data on patients who have received high-dose intensity-modulated radiotherapy (IMRT) with ADT. We report the long-term outcomes in a large cohort of patients treated with the combination of DE image-guided IMRT (IG-IMRT) and ADT. Patients with localized prostate cancer were identified from a centralized database across an integrated cancer center. All patients received DE IG-IMRT, combined with ADT, and had a minimum follow up of 12 months post-radiotherapy. All relapse and toxicity data were collected prospectively. Actuarial bDFS, metastasis-free survival, prostate cancer-specific survival, and multivariate analyses were calculated using the SPSS v20.0 statistical package. Seven hundred and eighty-two eligible patients were identified with a median follow up of 46 months. Overall, 4.3% of patients relapsed, 2.0% developed distant metastases, and 0.6% died from metastatic prostate cancer. At 5-years, bDFS was 88%, metastasis-free survival was 95%, and prostate cancer-specific survival was 98%. Five-year grade 2 genitourinary and gastrointestinal toxicity was 2.1% and 3.4%, respectively. No grade 3 or 4 late toxicities were reported. Pretreatment prostate specific antigen (P=0.001) and Gleason score (P=0.03) were significant in predicting biochemical failure on multivariate analysis. There is a high probability of tumor control with DE IG-IMRT combined with androgen deprivation, and this is a technique with a low probability of significant late toxicity. Our long term results corroborate the safety and efficacy of treating with IG-IMRT to high doses and compares favorably with published series for

    There is a lack of data on quality of life in long-term survivors of nasopharyngeal carcinoma (NPC) who have been treated with intensity-modulated radiation therapy (IMRT). We characterized long-term disease-specific and cognitive QoL in NPC survivors after IMRT. We conducted a cross-sectional study of surviving patients diagnosed and treated for NPC at our center with curative-intent IMRT, with or without chemotherapy. Patients who were deceased, still undergoing treatment, with known recurrent disease, or treated with RT modality other than IMRT were excluded. QoL was measured by FACT-NP and FACT-Cog. Between May and November 2013, 44 patients completed cognitive (FACT-Cog), general (FACT-G), and NPC-specific (NPCS) QoL assessments. Patients were categorized into 4 cohorts based on duration since IMRT (≤2.5, >2.5–6, >6–10, and >10–16 years). There was no significant difference in age (p = 0.20) or stage ((I/II vs III/IV: p = 0.78) among the cohorts. The 4 cohorts differed overall for all QoL measures (ANOVA: p < 0.02 for each), due to improved scores >2.5–6 years post-IMRT compared with ≤2.5 years post-IMRT (post hoc tests: p ≤ 0.04 for each). No differences were observed between >2.5–6 and >6–10 years post-IMRT, but lower mean FACT-Cog and NPCS scores were observed for >10 years compared to >2.5–6 years post-IMRT (post hoc: p < 0.05 for each). All QoL measures were low during the initial recovery period (≤2.5 years) and were higher by 6 years post-IMRT. At >10 years post-IMRT, lower scores were observed in the domains of NPC-specific and cognitive QoL. Survivors of NPC, even if treated with IMRT, are at risk for detriment in domain-specific QoL measures at very long-term follow-up

    To determine long-term adherence to a 5 day antibiotic course guideline for treating intensive care unit (ICU)-acquired Gram-negative bacteria (GNB) infections. Descriptive analysis of patient-level data on all GNB-active antibiotics prescribed from day 3 and all GNB identified in clinical samples in 5350 patients admitted to a 30 bed general ICU between 2002 and 2009. Four thousand five hundred and eleven of 5350 (84%) patients were treated with one or more antibiotics active against GNB commenced from day 3. Gentamicin was the most frequently prescribed antibiotic (92.2 days of therapy/1000 patient-days). Only 6% of courses spanned >6 days of therapy and 89% of antibiotic therapy days were with a single antibiotic active against GNB. There was no significant difference between gentamicin and meropenem in the number of first courses in which a resistant GNB was identified in blood cultures [11/1177 (0.9%) versus 5/351 (1.4%); P = 0.43] or respiratory tract specimens [59/951 (6.2%) versus 17/246 (6.9%); P = 0.68] at the time of starting therapy. This study demonstrates long-term adherence to a 5 day course antibiotic guideline for treatment of ICU-associated GNB infections. This guideline is a potential antibiotic-sparing alternative to currently recommended dual empirical courses extending to ≥7 days. © The Author 2014.

    Our aim was to determine long-term survival and quality of life of patients admitted to a surgical intensive care unit (ICU) because of sepsis or trauma. This was an observational study conducted in an 11-bed, closed surgical ICU at a 860-bed teaching general hospital over a 1-year period (January 2003 to December 2003). Patients were divided into two groups according to admission diagnoses: group 1 included patients with sepsis; and group 2 included patients with trauma (polytrauma, multiple trauma, head injury, or spinal injury). Quality of life was assessed after 2 years following ICU admission using the EuroQol 5D questionnaire. A total of 164 patients (98 trauma patients and 66 patients with sepsis) were included in the study. Trauma patients were younger than patients with sepsis (53 +/- 21 years versus 64 +/- 13 years; P Trauma patients stayed longer on the general ward (35 +/- 44 days versus 17 +/- 24 days; P trauma group (surgical ICU survival: 60% versus 74%; in-hospital survival: 42% versus 62%; post-hospital survival: 78% versus 92%; cumulative 2-year survival: 33% versus 57%; P quality of life in all five dimensions of the EuroQol 5D between groups: 60% of patients had signs of depression, almost 60% had problems in usual activities and 56% had pain. Patients with sepsis treated in a surgical ICU have higher short-term and long-term mortality than do trauma patients. However, quality of life is reduced to the same level in both groups.

    To investigate the insulin requirement profiles during short-term intensive continuous subcutaneous insulin infusion (CSII) in patients with newly diagnosed type 2 diabetes and its relationship with long-term glycemic remission. CSII was applied in 104 patients with newly diagnosed type 2 diabetes. Daily insulin doses were titrated and recorded to achieve and maintain euglycemia for 2 weeks. Measurements of blood glucose, lipid profiles as well as intravenous glucose tolerance tests were performed before and after the therapy. Afterwards, patients were followed up for 1 year. Total daily insulin dose (TDD) was 56.6±16.1IU at the first day when euglycemia was achieved (TDD-1). Thereafter, TDD progressively decreased at a rate of 1.4±1.0IU/day to 36.2±16.5IU at the end of the therapy. TDD-1 could be estimated with body weight, FPG, triglyceride and waist circumference in a multiple linear regression model. Decrement of TDD after euglycemia was achieved (ΔTDD) was associated with reduction of HOMA-IR (r=0.27, P=0.008) but not with improvement in β cell function. Patients in the lower tertile of ΔTDD had a significantly higher risk of hyperglycemia relapse than those in the upper tertile within 1 year (HR 3.4, 95%CI [1.4, 8.4], P=0.008). There is a steady decline of TDD after euglycemia is achieved in patients with newly diagnosed type 2 diabetes treated with CSII, and ΔTDD is associated with a better long-term glycemic outcome.

    Purpose: To compare the long-term quality of life among patients treated with and without intensity-modulated radiotherapy (IMRT) for head-and-neck cancer. Methods and Materials: University of Washington Quality of Life instrument scores were reviewed for 155 patients previously treated with radiation therapy for locally advanced head-and-neck cancer. All patients were disease free and had at least 2 years of follow-up. Eighty-four patients (54%) were treated with IMRT. The remaining 71 patients (46%) were treated with three-dimensional conformal radiotherapy (3D CRT) by use of initial opposed lateral fields matched to a low anterior neck field. Results: The mean global quality of life scores were 67.5 and 80.1 for the IMRT patients at 1 and 2 years, respectively, compared with 55.4 and 57.0 for the 3D CRT patients, respectively (p < 0.001). At 1 year after the completion of radiation therapy, the proportion of patients who rated their global quality of life as “very good” or “outstanding” was 51% and 41% among patients treated by IMRT and 3DCRT, respectively (p = 0.11). At 2 years, the corresponding percentages increased to 73% and 49%, respectively (p < 0.001). On multivariate analysis accounting for sex, age, radiation intent (definitive vs. postoperative), radiation dose, T stage, primary site, use of concurrent chemotherapy, and neck dissection, the use of IMRT was the only variable independently associated with improved quality of life (p = 0.01). Conclusion: The early quality of life improvements associated with IMRT not only are maintained but apparently become more magnified over time. These data provide powerful evidence attesting to the long-term benefits of IMRT for head-and-neck cancer.

    Djemaa, A.

    2009-01-01

    Among the energy users in France and Europe, some industrial sectors are very important and should have a key role when assessing the final energy demand patterns in the future. The aim of our work is to apply a prospective model for the long range analysis of energy/technology choices in the industrial sector, focussing on the energy-intensive sectors. The modelling tool applied in this study is the TIMES model (family of best known MARKAL model). It is an economic linear programming model generator for local, national or multi regional energy systems, which provides a technology-rich basis for estimating energy dynamics over a long term, multi period time. We illustrate our work with nine energy-intensive industrial sectors: paper, steel, glass, cement, lime, tiles, brick, ceramics and plaster. It includes a detailed description of the processes involved in the production of industrial products, providing typical energy uses in each process step. In our analysis, we identified for each industry, several commercially available state-of-the-art technologies, characterized and chosen by the Model on the basis of cost effectiveness. Furthermore, we calculated potential energy savings, carbon dioxide emissions' reduction and we estimated the energy impact of a technological rupture. This work indicates that there still exists a significant potential for energy savings and carbon dioxide emissions' reduction in all industries. (author)

    The objective of this study was to investigate the effects of a low-intensity wheelchair training on propulsion technique in inactive people with long-term spinal cord injury. Participants in this multicenter nonblinded randomized controlled trial were inactive manual wheelchair users with spinal cord injury for at least 10 yrs (N = 29), allocated to exercise (n = 14) or no exercise. The 16-wk training consisted of wheelchair treadmill propulsion at 30%-40% heart rate reserve or equivalent in rate of perceived exertion, twice a week, 30 mins per session. Propulsion technique was assessed at baseline as well as after 8, 16, and 42 wks during two submaximal treadmill-exercise blocks using a measurement wheel attached to a participant's own wheelchair. Changes over time between the groups were analyzed using Mann-Whitney U tests on difference scores (P propulsion technique were not found in this group. Perhaps, substantial effects require a higher intensity or frequency. Investigating whether more effective and feasible interventions exist might help reduce the population's risk of upper-body joint damage during daily wheelchair propulsion.

    2017-02-01

    Long-term hospitalizations in psychiatry raise the question of desocialisation of the patients and the inherent costs. Individual indicators were extracted from a medical administrative database containing full-time psychiatric hospitalizations for the period 2011-2013 of people over 16 years old living in the French region of Nord-Pas-de-Calais. We calculated the proportion of people who had experienced a hospitalization with a duration of 292 days or more during the study period. A bivariate analysis was conducted, then ecological data (level of health-care offer, the deprivation index and the size of the municipalities of residence) were included into a multilevel regression model in order to identify the factors significantly related to variability of long-term hospitalization rates. Among hospitalized individuals in psychiatry, 2.6% had had at least one hospitalization of 292 days or more during the observation period; the number of days in long-term hospitalization represented 22.5% of the total of days of full-time hospitalization in psychiatry. The bivariate analysis revealed that seniority in the psychiatric system was strongly correlated with long hospitalization rates. In the multivariate analysis, the individual indicators the most related to an increased risk of long-term hospitalization were: total lack of autonomy (OR=9.0; 95% CI: 6.7-12.2; P<001); diagnoses of psychological development disorders (OR=9.7; CI95%: 4.5-20.6; P<.001); mental retardation (OR=4.5; CI95%: 2.5-8.2; P<.001): schizophrenia (OR=3.0; CI95%: 1.7-5.2; P<.001); compulsory hospitalization (OR=1.7; CI95%: 1.4-2.1; P<.001); having experienced therapeutic isolation (OR=1.8; CI95%: 1.5-2.1; P<.001). Variations of long-term hospitalization rates depending on the type of establishment were very high, but the density of hospital beds or intensity of ambulatory activity services were not significantly linked to long-term hospitalization. The inhabitants of small urban units had

    Full Text Available Abstract Background The age-related deterioration of physiological capacities such as muscle strength and balance is associated with increased dependence. Understanding the contribution of physical fitness components to functional performance facilitates the development of adequate exercise interventions aiming at preservation of function and independence of older people. The aim of the study was to investigate the relationship between physical fitness components and functional performance in older people living in long-term care facilities. Methods Design cross-sectional study Subjects 226 persons living in long-term care facilities (mean age: 81.6 ± 5.6. Outcome measures Physical fitness and functional performance were measured by performance-based tests. Results Knee and elbow extension strength were significantly higher in men (difference = 44.5 and 50.0 N, respectively, whereas women were more flexible (difference sit & reach test = 7.2 cm. Functional performance was not significantly different between the genders. In men, motor coordination (eye-hand coordination and measures of strength were the main contributors to functional performance, whereas in women flexibility (sit and reach test and motor coordination (tandem stance and eye-hand coordination played a major role. Conclusion The results of this study show that besides muscle strength, fitness components such as coordination and flexibility are associated with functional performance of older people living in long-term care facilities. This suggests that men and women living in long-term care facilities, differ considerably concerning the fitness factors contributing to functional performance. Women and men may, therefore, need exercise programs emphasizing different fitness aspects in order to improve functional performance.

    Increasing physical activity in patients with severe mental illness is believed to have positive effects on physical health, psychiatric symptoms and as well quality of life. Till now, little is known about the relationship between physical activity and quality of life in long-term hospitalized patients with severe mental illness and knowledge of the determinants of behavioural change is lacking. The purpose of this study was to elucidate the relationship between objectively measured physical activity and quality of life, and explore modifiable psychological determinants of change in physical activity in long-term hospitalized patients with severe mental illness. In 184 inpatients, physical activity was measured using an accelerometer (ActiGraph GTX+). Quality of life was assessed by EuroQol-5D and WHOQol-Bref. Attitude and perceived self-efficacy towards physical activity were collected using the Physical Activity Enjoyment Scale and the Multidimensional Self Efficacy Questionnaire, respectively. Patient and disease characteristics were derived retrospectively from electronic patient records. Associations and potential predictors were analysed using hierarchical regression. Physical activity was positively related with and a predictor of all quality of life outcomes except on the environmental domain, independent of patient and disease characteristics. However, non-linear relationships showed that most improvement in quality of life lies in the change from sedentary to light activity. Attitude and self-efficacy were not related to physical activity. Physical activity is positively associated with quality of life, especially for patients in the lower spectrum of physical activity. An association between attitude and self-efficacy and physical activity was absent. Therefore, results suggest the need of alternative, more integrated and (peer-)supported interventions to structurally improve physical activity in this inpatient population. Slight changes from sedentary

    To compare psychological recovery of patients receiving structured nurse-led follow-up and patients receiving usual care after intensive care discharge. Quasi-experimental study. Single centre, university hospital, mixed intensive care patient population. Symptoms of post-traumatic stress disorder, anxiety and depression measured three and four times over 12 months after intensive care discharge. Disturbing memories of the intensive care stay and psychological reactions (that one's life was in danger, threat to physical integrity, intense fear, helplessness, horror) three months after intensive care. A mixed effect model tested differences between the groups over time and regression model predicted post-traumatic stress at three months. The experimental group had significantly more symptoms of post-traumatic stress and anxiety than the control group over the 12 months. Patients from both groups had severe symptoms of post-traumatic stress. Patients with post-traumatic stress at three months had disturbing memories and psychological reactions. The structured nurse-led follow-up did not improve patients' measured outcomes of psychological recovery after intensive care. Patients with severe symptoms of post-traumatic stress are of concern. Emphasis needs to be placed on disturbing memories of the intensive care stay and psychological reactions when constructing intensive care nurse-led follow-up. Copyright © 2017 Elsevier Ltd.

    The optimal time to initiate renal replacement therapy (RRT) in intensive care unit (ICU) patients with acute kidney injury (AKI) is unclear. We examined the impact of early RRT on long-term mortality, risk of chronic kidney disease (CKD), and end-stage renal disease (ESRD). This cohort study included all adult patients treated with continuous RRT in the ICU at Aarhus University Hospital, Skejby, Denmark (2005-2015). Data were obtained from a clinical information system and population-based registries. Early treatment was defined as RRT initiation at AKI stage 2 or below, and late treatment was defined as RRT initiation at AKI stage 3. Inverse probability of treatment (IPT) weights were computed from propensity scores. The IPT-weighted cumulative risk of CKD (estimated glomerular filtration rate regression. The mortality, CKD, and ESRD analyses included 1213, 303, and 617 patients, respectively. The 90-day mortality in the early RRT group was 53.6% compared with 46.0% in the late RRT group (HR 1.24, 95% CI 1.03-1.48). The 90-day to 5-year mortality was 37.7% and 41.5% in the early and late RRT groups, respectively (HR 0.95, 95% CI 0.70-1.29). The 5-year risk of CKD was 35.9% in the early RRT group and 44.9% in the late RRT group (HR 0.74, 95% CI 0.46-1.18). The 5-year risk of ESRD was 13.3% in the early RRT group and 16.7% in the late RRT group (HR 0.79, 95% CI 0.47-1.32). Early initiation was associated with increased 90-day mortality. In patients surviving to day 90, early initiation was not associated with a major impact on long-term mortality or risk of CKD and ESRD. Despite potential residual confounding due to the observational design, our findings do not support that early RRT initiation is superior to late initiation.

    Purpose: This report describes the long-term outcomes of a prospective trial of intensity modulated radiation therapy (IMRT), integrating a {sup 111}In capromab pendetide (ProstaScint) scan-directed simultaneous integrated boost (SIB) for localized prostate cancer. Methods and Materials: Seventy-one patients with T1N0M0 to T4N0M0 prostate cancer were enrolled, and their ProstaScint and pelvic computed tomography scans were coregistered for treatment planning. The entire prostate received 75.6 Gy in 42 fractions with IMRT, whereas regions of increased uptake on ProstaScint scans received 82 Gy as an SIB. Patients with intermediate- and high-risk disease also received 6 months and 12 months of adjuvant hormonal therapy, respectively. Results: The study enrolled 31 low-, 30 intermediate-, and 10 high-risk patients. The median follow-up was 120 months (range, 24-150 months). The 10-year biochemical control rates were 85% for the entire cohort and 84%, 84%, and 90% for patients with low-, intermediate-, and high-risk disease, respectively. The 10-year survival rate of the entire cohort was 69%. Pretreatment prostate-specific antigen level >10 ng/mL and boost volume of >10% of the prostate volume were significantly associated with poorer biochemical control and survival. The outcomes were compared with those of a cohort of 302 patients treated similarly but without the SIB and followed up for a median of 91 months (range, 6-138 months). The 5- and 10-year biochemical control rates were 86% and 61%, respectively, in patients without the SIB compared with 94% and 85%, respectively, in patients in this trial who received the SIB (P=.02). The cohort that received an SIB did not have increased toxicity. Conclusions: The described IMRT strategy, integrating multiple imaging modalities to administer 75.6 Gy to the entire prostate with a boost dose of 82 Gy, was feasible. The addition of the SIB was associated with greater biochemical control but not toxicity. Modern

    Making a decision upon the right choice of a material appropriate to a given application should be based on taking into account several parameters as follows: cost, standards, regulations, safety, recycling, chemical properties, supplying, transformation, forming, assembly, mechanical and physical properties as well as the behaviour in practical conditions. Data taken from a private communication (J.H.Davidson) are reproduced presenting the life time range of materials from a couple of minutes to half a million hours corresponding to applications from missile technology up to high-temperature nuclear reactors or steam turbines. In the case of deep storage of nuclear waste the time required is completely different from these values since we have to ensure the integrity of the storage system for several thousand years. The vitrified nuclear wastes should be stored in metallic canisters made of iron and carbon steels, stainless steels, copper and copper alloys, nickel alloys or titanium alloys. Some of these materials are passivating metals, i.e. they develop a thin protective film, 2 or 3 nm thick - the so-called passive films. These films prevent general corrosion of the metal in a large range of chemical condition of the environment. In some specific condition, localized corrosion such as the phenomenon of pitting, occurs. Consequently, it is absolutely necessary to determine these chemical condition and their stability in time to understand the behavior of a given material. In other words the corrosion system is constituted by the complex material/surface/medium. For high level nuclear wastes the main features for resolving problem are concerned with: geological disposal; deep storage in clay; waste metallic canister; backfill mixture (clay-gypsum) or concrete; long term behavior; data needed for modelling and for predicting; choice of appropriate solution among several metallic candidates. The analysis of the complex material/surface/medium is of great importance

In the same group of patients, androgen deprivation therapy (ADT has been shown to confer a survival benefit when combined with radiotherapy doses of up to 70 Gy; however, there is currently little long-term data on patients who have received high-dose intensity-modulated radiotherapy (IMRT with ADT. We report the long-term outcomes in a large cohort of patients treated with the combination of DE image-guided IMRT (IG-IMRT and ADT. Methods and materials: Patients with localized prostate cancer were identified from a centralized database across an integrated cancer center. All patients received DE IG-IMRT, combined with ADT, and had a minimum follow up of 12 months post-radiotherapy. All relapse and toxicity data were collected prospectively. Actuarial bDFS, metastasis-free survival, prostate cancer-specific survival, and multivariate analyses were calculated using the SPSS v20.0 statistical package. Results: Seven hundred and eighty-two eligible patients were identified with a median follow up of 46 months. Overall, 4.3% of patients relapsed, 2.0% developed distant metastases, and 0.6% died from metastatic prostate cancer. At 5-years, bDFS was 88%, metastasis-free survival was 95%, and prostate cancer-specific survival was 98%. Five-year grade 2 genitourinary and gastrointestinal toxicity was 2

    Objective The Nagasaki Kunchi Festival is one of the most famous festivals in Nagasaki. The bearers the floats that are used in this festival undergo long-term training for the performance. However, there have not been any studies on the effects of this training on the health of the float bearers. Methods Thirty-four men ranging in age from 20 to 49 years (mean age: 35.77.6 years) were included in the study. We examined the following parameters before and after the training: body weight (BW), body mass index (BMI), body fat percentage, muscle volume, systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse rate (PR), pulse pressure (PP), bearing power, arterial pressure volume index (API), and arterial velocity pulse index (AVI). Results For all participants, the BW, BMI, body fat percentage, and PR were significantly decreased, and the muscle volume and bearing power were significantly increased after the training; however, there were no significant changes in the SBP, DBP, PP, API, or AVI. In the participants with hypertension, in addition to decreases in BW, BMI, body fat percentage, PR, and PP, the SBP, DBP, and API were significantly decreased after the training. Conclusion Training for bearing a float during Nagasaki Kunchi effectively improved the body structure of all participants and reduced the BP and API in participants with hypertension.

AC was modified by three methods: 1)pyrolysis with iron ethylenediaminetetraacetic acid (AC-Fe), 2)heat treatment (AC-heat), and 3)mixing with carbon black (AC-CB). The maximum power densities after one month with these AC cathodes were 35% higher with AC-Fe (1410±50mW m-2) and AC-heat (1400±20mW m-2), and 16% higher with AC-CB (1210±30mW m-2) than for plain AC (1040±20mW m-2), versus 1270±50mW m-2 for a Pt control. After 16months, the Pt cathodes produced only 250±10mW m-2. However, the AC-heat and AC-CB cathodes still produced 960-970mW m-2, whereas plain AC produced 860±60mW m-2. The performance of the AC cathodes was restored to >85% of the initial maximum power densities by cleaning with a weak acid solution. Based on cost considerations among the AC materials, AC-CB appears to be the best choice for long-term performance.

    Full Text Available Objectives: To assess the presence of depressive symptoms among older adults with long-term spinal cord injury and investigate the association with sociodemographic and injury characteristics; and to determine how potentially modifiable factors, i.e. secondary health conditions, sense of coherence, coping strategies and leisure-time physical activity, are associated with depressive symptoms. Design: Cross-sectional study. Subjects: A total of 122 individuals (70% men, injury levels C1–L5, American Spinal Injury Association Impairment Scale A–D, mean age 63 years, mean time since injury 24 years. Methods: Data from the Swedish Aging with Spinal Cord Injury Study, collected using the Geriatric Depression Scale-15, the 13-item Sense of Coherence Scale, the Spinal Cord Lesion-related Coping Strategies Questionnaire and the Physical Activity Recall Assessment for people with Spinal Cord Injury. Associations were analysed using multivariable linear regression. Results: A total of 29% reported clinically relevant depressive symptoms and 5% reported probable depression. Sense of coherence, the coping strategy Acceptance, neuropathic pain and leisure-time physical activity explained 53% of the variance in depressive symptoms. Conclusion: Older adults with long-term spinal cord injury report a low presence of probable depression. Mental health may be supported through rehabilitation that strengthens the ability to understand and confront life stressors, promotes acceptance of the injury, provides pain management and encourages participation in leisure-time physical activity.

    This study aimed to identify children's long-term placement trajectories following early child welfare involvement and the association of these trajectories with subsequent physical and behavioral well-being. Participants were 330 children who entered out-of-home care following a substantiated report of child abuse or neglect during infancy/early childhood and their caregivers. Participants were interviewed at child ages 4 and 12 years to assess children's physical and behavioral well-being and every 2 years in between to determine child placements. Latent Class Analyses identified four stable placement trajectories (i.e., adopted [32%], kinship care [15%], stable reunified [27%], and stable foster care [9%]), and two unstable trajectories (i.e., disrupted reunified [12%] and unstable foster care [5%]). Logistic regressions revealed that children in the unstable trajectories had significantly poorer physical and behavioral well-being than children in stable trajectories. Maltreated children placed in out-of-home care are at risk for long-term placement instability and poorer physical and behavioral well-being. © The Author 2015.

    Long-term safety of radioactive waste disposal facilities relies on the longevity of natural or engineered barriers designed to minimize the migration of contaminants from the facility into the environment. Especially near surface disposal facilities, such as planned by ONDRAF/NIRAS for the Dessel site in Belgium, long-term safety relies almost exclusively on the containment ability of the engineered barriers (EB) with concrete being the most important EB material used. Concrete is preferred over other materials mainly due to its favourable chemical properties resulting in a high chemical retention capacity, and owing to its good hydraulic isolation properties. However, due to the long time frames typically involved in safety assessment, the chemical, physical and mechanical properties of concrete evolve in time. The alterations in concrete mineralogy also cause changes in pH and sorption behaviour for many radionuclides during chemical degradation processes. Application of dynamic sorption of concrete requires an adequate knowledge of long-term concrete degradation processes, knowledge of the effect of changing mineralogy to sorption of radionuclides and knowledge of large-scale system behaviour over time. Moreover, when applied to safety assessment models, special attention is required to assure robustness and transparency of the implementation. The discussion in this paper focuses on the sorption properties of concrete; selection of data, rescaling issues and on the hypotheses used to build a robust and yet transparent dynamic model for large-scale concrete structures for assessing the long-term performance. In this paper we summarize the steps required for the appropriate use of sorption values for large-scale cementitious components accounting for long-term concrete degradation in safety assessment studies. Four steps were recognized through the safety assessment in the framework of the license application for the near-surface disposal facility in Dessel

    This qualitative study evaluated the effect of dining room physical environmental changes on staff practices and residents' mealtime experiences in two units of a long-term care facility in Edmonton, Canada. Focus groups with staff (n = 12) and individual interviews with unit managers (n = 2) were conducted. We also developed and used the Dining Environment Assessment Protocol (DEAP) to conduct a systematic physical environmental evaluation of the dining rooms. Four themes emerged on the key influences of the renovations: (a) supporting independence and autonomy, (b) creating familiarity and enjoyment, (c) providing a place for social experience, and (d) challenges in supporting change. Feedback from the staff and managers provided evidence on the importance of physical environmental features, as well as the integral nature of the role of the physical environment and organizational support to provide person-centered care for residents. © The Author(s) 2015.

    To examine the effect of happiness and life satisfaction on health. Longitudinal data from waves 1 and 3, conducted in 2001 and 2004, respectively, of the Household Income and Labour Dynamics in Australia survey. Australia. A total of 9981 respondents aged 18 years and older. Outcomes were self-reported health; the absence of long-term, limiting health conditions; and physical health. Happiness was assessed with the following question: "During the past 4 weeks, have you been a happy person"? Life satisfaction was determined with the following question: "All things considered, how satisfied are you with your life"? We used multiple regression analysis to estimate odds ratios (ORs), beta coefficients (beta), and 95% confidence intervals (CIs) for the associations between baseline happiness or life satisfaction and health at wave 3. Baseline happiness and life satisfaction both were positively associated at wave 3 with excellent, very good, or good health (OR = 1.50, CI = 1.33-1.70, p < .0001; and OR = 1.62, CI = 1.27-2.08, p < .0001, respectively); with the absence of long-term, limiting health conditions (OR = 1.53, CI = 1.35-1.75, p < .0001; and OR = 1.51, CI = 1.25-1.82, p < .0001, respectively); and with higher physical health levels (beta = .99, CI = .60-1.39, p < .0001; and beta = .99, CI = .20-1.78, p < .0145, respectively). This study showed that happier people and those who were more satisfied with their lives at baseline reported better health (self-rated health; absence of limiting, long-term conditions; and physical health) at the 2-year follow-up when adjusted for baseline health and other relevant covariates.

    Introduction The long-term risk of smoking in diabetic patients with stable ischemic heart disease (SIHD) is unknown. We sought to analyze the impact of smoking on outcomes of diabetic patients with SIHD when other cardiovascular risk factors are being aggressively treated. Methods The Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial randomized 2368 diabetics with SIHD to intensive medical therapy (IMT) with prompt revascularization or IMT alone. Smoking status was obtained at baseline, 6 months, and 1, 2, 3, 4 and 5 years. The primary endpoint of interest was all-cause mortality. Results Of 2360 patients, 33.1% of patients never smoked, 54.4% were former smokers, and 12.5% were current smokers. The rate of all-cause mortality was greater for current (2.5 deaths/100 patient-years) and former smokers (3.1 deaths/100 patient-years) than never smokers (2.1 deaths/100 patient-years) (P = 0.007). Cardiac death, cardiovascular death, fatal or nonfatal myocardial infarction, and fatal or nonfatal stroke were not increased in current or former smokers compared with never smokers. Compared with never smokers, current smokers experienced a 49% increased hazard of death (Hazard Ratio (HR) 1.49, 95% Confidence Interval (CI): 0.97-2.29, P = 0.07) whereas former smokers had a 37% increased hazard of death (HR 1.37, 95% CI: 1.04-2.79, P = 0.02) when considering smoking status as a time-dependent variable and adjusting for factors that differed by smoking status. Conclusions Current and former smoking are associated with increased all-cause mortality in diabetics with SIHD but not with increased cardiovascular morbidity or mortality.

    Purpose: In 2007, we published our initial experience in treating inoperable non-small-cell lung cancer (NSCLC) with intensity-modulated radiation therapy (IMRT). The current report is an update of that experience with long-term follow-up. Methods and Materials: Patients in this retrospective review were 165 patients who began definitive radiotherapy, with or without chemotherapy, for newly diagnosed, pathologically confirmed NSCLC to a dose of {>=}60 Gy from 2005 to 2006. Early and late toxicities assessed included treatment-related pneumonitis (TRP), pulmonary fibrosis, esophagitis, and esophageal stricture, scored mainly according to the Common Terminology Criteria for Adverse Events 3.0. Other variables monitored were radiation-associated dermatitis and changes in body weight and Karnofsky performance status. The Kaplan-Meier method was used to compute survival and freedom from radiation-related acute and late toxicities as a function of time. Results: Most patients (89%) had Stage III to IV disease. The median radiation dose was 66 Gy given in 33 fractions (range, 60-76 Gy, 1.8-2.3 Gy per fraction). Median overall survival time was 1.8 years; the 2-year and 3-year overall survival rates were 46% and 30%. Rates of Grade {>=}3 maximum TRP (TRP{sub max}) were 11% at 6 months and 14% at 12 months. At 18 months, 86% of patients had developed Grade {>=}1 maximum pulmonary fibrosis (pulmonary fibrosis{sub max}) and 7% Grade {>=}2 pulmonary fibrosis{sub max}. The median times to maximum esophagitis (esophagitis{sub max}) were 3 weeks (range, 1-13 weeks) for Grade 2 and 6 weeks (range, 3-13 weeks) for Grade 3. A higher percentage of patients who experienced Grade 3 esophagitis{sub max} later developed Grade 2 to 3 esophageal stricture. Conclusions: In our experience, using IMRT to treat NSCLC leads to low rates of pulmonary and esophageal toxicity, and favorable clinical outcomes in terms of survival.

    This study aimed to investigate if the impact of both recent and long-term physical activity on age-related cognitive decline would be modified by sex. One-hundred thirty-five men (N = 67) and women (N = 68) aged 18 to 80 years completed the Modifiable Activity Questionnaire and the Historical Leisure Activity Questionnaire. A composite score of cognitive functions was computed from five experimental tasks. Hierarchical regression analyses performed to test the moderating effect of recent physical activity on age-cognition relationship had not revealed significant result regardless of sex. Conversely, past long-term physical activity was found to slow down the age-related cognitive decline among women (β = 0.22, p = .03), but not men. The findings support a lifecourse approach in identifying determinants of cognitive aging and the importance of taking into account the moderating role of sex. This article presented potential explanations for these moderators and future avenues to explore.

    Full Text Available Background: Monitored physical activities in patients with adolescent idiopathic scoliosis (AIS have been shown to improve physical performance, endurance and cardiopulmonary function and may be assessed by the 6-min walk test (6MWT. We aimed to evaluate the long-term results of the 6MWT after a rehabilitation protocol employed before surgical correction for AIS. Methods: This prospective randomized clinical trial studied the impact of a 4-month pre-operative physical rehabilitation protocol on post-operative cardiopulmonary function and physical endurance, by using the 6MWT, in patients with AIS submitted to surgical correction, comparing them to matched controls without physical rehabilitation. Studied variables were heart and respiratory rate, systolic and diastolic blood pressure, peripheral blood oxygen saturation, Borg score, and distance walked. Patients were assessed at baseline, after 4 months of rehabilitation, and 3, 6 and 12 months post-operatively. Results: A total of 50 patients with AIS were included in the study and allocated blindly, by simple randomization, into either one of the two groups, with 25 patients each: study group (pre-operative physical rehabilitation and control group. The physical rehabilitation protocol promoted significant progressive improvement in heart and respiratory rate, peripheral blood oxygen saturation, distance walked, and level of effort assessed by the Borg scale after surgery. Conclusions: Post-surgical recovery, evaluated by 6MWT, was significantly better in patients who underwent a 4-month pre-operative physical rehabilitation protocol.

    Soil compaction is a major problem of soils on dumped mining substrates in Lusatia, Germany. Deep ripping and cultivation of deep rooting plant species are considered to be effective ways of agricultural recultivation. Six years after experiment start, we studied the effect of initial deep soil loosening (i.e. down to 65 cm) on root systems of rye (Secale cereale) and alfalfa (Medicago sativa) and on soil physical parameters. We conducted a soil monolith sampling for each treatment (deep loosened and unloosened) and for each plant species (in three replicates, respectively) to determine root diameter, length density and dry mass as well as soil bulk density. Further soil physical analysis comprised water retention, hydraulic conductivity and texture in three depths. The results showed different reactions of the root systems of rye and alfalfa six years after deep ripping. In the loosened soil the root biomass of the rye was lower in depths of 20-40 cm and the root biomass of alfalfa was also decreased in depths of 20-50 cm together with a lower root diameter for both plant species. Moreover, total and fine root length density was higher for alfalfa and vice versa for rye. The soil physical parameters such as bulk density showed fewer differences, despite a higher bulk density in 30-40cm for the deep loosened rye plot which indicates a more pronounced plough pan.

    Purpose: We report a Phase II trial assessing the acute and late toxicities of intensity-modulated radiation therapy (IMRT), long-term androgen suppression (LTAS), and bevacizumab in patients with high-risk localized prostate cancer. Methods and Materials: We treated 18 patients with LTAS with bicalutamide and goserelin in combination with bevacizumab and IMRT. Bevacizumab (10 mg/kg every 2 weeks) was administered for the first 16 weeks, and 15 mg/kg was then given every 3 weeks for 12 additional weeks, with an IMRT dose of 77.9 Gy to the prostate, 64.6 Gy to the seminal vesicles, and 57 Gy to the pelvic lymph nodes. Patients were eligible if they had clinical stage T2b to T4, a Gleason sum score of 8 to 10, or a prostate- specific antigen level of 20ng/mL or greater. The primary endpoint of the study was evaluation of acute and late toxicities. Results: The median age was 69 years, with a median pretreatment prostate-specific antigen level of 12.5 ng/mL and Gleason score of 8. The pretreatment clinical stage was T1c in 4 patients, T2 in 11, and T3 in 3. All patients completed IMRT with median follow-up of 34 months (range, 28-40 months) The most common Grade 2 or higher toxicities were hypertension (61% of patients with Grade 2 and 11% with Grade 3), proteinuria (28% with Grade 2 and 6% with Grade 3), and leucopenia (28% with Grade 2). No Grade 4 or higher acute toxicities were reported. Late toxicities included proctitis (6% of patients with Grade 2 and 11% with Grade 3), rectal bleeding (6% with Grade 2 and 11% with Grade 3), hematuria (6% with Grade 2), proteinuria (17% with Grade 2), hyponatremia (6% with Grade 3), cystitis (6% with Grade 3), and urinary retention (6% with Grade 2 and 11% with Grade 3). Grade 4 prostatitis occurred in 1 patient (6%). Conclusions: Bevacizumab does not appear to exacerbate the acute effects of IMRT. Late toxicities may have been worsened with this regimen. Further investigations of bevacizumab with LTAS and IMRT should be

    Purpose: To assess the efficacy of individual sentinel node (SN)-guided pelvic intensity modulated radiation therapy (IMRT) by determining nodal clearance rate [(n expected nodal involvement − n observed regional recurrences)/n expected nodal involvement] in comparison with surgically staged patients. Methods and Materials: Data on 475 high-risk prostate cancer patients were examined. Sixty-one consecutive patients received pelvic SN-based IMRT (5 × 1.8 Gy/wk to 50.4 Gy [pelvic nodes + individual SN] and an integrated boost with 5 × 2.0 Gy/wk to 70.0 Gy to prostate + [base of] seminal vesicles) and neo-/adjuvant long-term androgen deprivation therapy; 414 patients after SN–pelvic lymph node dissection were used to calculate the expected nodal involvement rate for the radiation therapy sample. Biochemical control and overall survival were estimated for the SN-IMRT patients using the Kaplan-Meier method. The expected frequency of nodal involvement in the radiation therapy group was estimated by imputing frequencies of node-positive patients in the surgical sample to the pattern of Gleason, prostate-specific antigen, and T category in the radiation therapy sample. Results: After a median follow-up of 61 months, 5-year OS after SN-guided IMRT reached 84.4%. Biochemical control according to the Phoenix definition was 73.8%. The nodal clearance rate of SN-IMRT reached 94%. Retrospective follow-up evaluation is the main limitation. Conclusions: Radiation treatment of pelvic nodes individualized by inclusion of SNs is an effective regional treatment modality in high-risk prostate cancer patients. The pattern of relapse indicates that the SN-based target volume concept correctly covers individual pelvic nodes. Thus, this SN-based approach justifies further evaluation, including current dose-escalation strategies to the prostate in a larger prospective series.

    It is important to understand the impact of texture and organic carbon (OC) on soil structure development. Only few studies investigated this for silt-dominated soils. In this study, soil physical properties were determined on samples from a controlled experiment (Static Fertilization Experiment...... hydraulic conductivity. The management resulted in a distinct gradient in OC. A bulk density gradient developed from differences in amount of clay not complexed with OC. This gradient in bulk density mainly affected content of pores larger than 3 [mu]m. The air-connected porosity measured by a pycnometer...

    Mean arterial pressure (MAP) is surprisingly similar across different species of mammals, and it is, in general, not known which factors determine the arterial pressure level. Mammals often have a pronounced capacity for sustained physical performance. This capacity depends on the vasculature...... having a flow reserve that comes into play as tissue metabolism increases. We hypothesize that microvascular properties allowing for a large vascular flow reserve is linked to the level of the arterial pressure.To study the interaction between network properties and network inlet pressure, we developed...

'NHV' is a rehabilitation services program comprised of non-governmental organizations (NGOs (N, local health departments (H, and professional rehabilitation volunteers (V which aims to improve long-term physical functioning in survivors of the 2008 Sichuan earthquake. We aimed to evaluate the effectiveness of the NHV program. METHODS/FINDINGS: 510 of 591 enrolled earthquake survivors participated in this longitudinal quasi-experimental study (86.3%. The early intervention group (NHV-E consisted of 298 survivors who received institutional-based rehabilitation (IBR followed by community-based rehabilitation (CBR; the late intervention group (NHV-L was comprised of 101 survivors who began rehabilitation one year later. The control group of 111 earthquake survivors did not receive IBR/CBR. Physical functioning was assessed using the Barthel Index (BI. Data were analyzed with a mixed-effects Tobit regression model. Physical functioning was significantly increased in the NHV-E and NHV-L groups at follow-up but not in the control group after adjustment for gender, age, type of injury, and time to measurement. We found significant effects of both NHV (11.14, 95% CI 9.0-13.3 and sponaneaous recovery (5.03; 95% CI 1.73-8.34.

    2016-01-01

    Purpose: To determine if the flipped class format has an effect on examination results for a radiologic technologist (RT) program and discuss benefits from creating video resources. Methods: From 2001–2015, students had taken both a radiological physics and quality control (QC) class as a part of their didactic training. In 2005/2006, the creation of videos of didactic lectures and QC test demonstrations allowed for a flip where content was studied at home while exercises and reviews were done in-class. Final examinations were retrospectively reviewed from this timeframe. 12 multiple choice physics questions (MCP) and 5 short answer QC questions (SAQC) were common to pre and post flip exams. The RT program’s ARRT exam scores were also obtained and compared to national averages. Results: In total, 36 lecture videos and 65 quality control videos were created for the flipped content. Data was ∼2.4GB and distributed to students via USB or CD media. For MCP questions, scores improved by 7.9% with the flipped format and significance (Student’s t-test, p<0.05) was found for 3 of the 12 questions. SAQC questions showed improvement by 14.6% and significance was found for 2 of the 5 questions. Student enrollment increased from ∼14 (2001–2004) to ∼23 students (2005–15). Content was continuously added post-flip due to the efficiency of delivery. The QC class in 2003 covered 45 test setups in-class while 65 were covered with video segments in 2014. Flipped materials are currently being repurposed. In 2015, this video content was restructured into an ARRT exam review guide and in 2016, the content was reorganized for fluoroscopy training for physicians. Conclusion: We believe that flipped classes can improve efficiency of content delivery and improve student performance even with an increase in class size. This format allows for flexibility in learning as well as re-use in multiple applications.

    There have been just a few studies examining the influence of detraining on obese boys. They conclude that any gains regress to the untrained control values during the detraining period. The objective of the present study was thus to evaluate the effects of detraining (6 months) on metabolic syndrome after two types of intervention (both 31 months), one of an exercise program alone and the other of a diet-plus-exercise program, in obese boys. The participants were 18 sedentary boys (8- 11 years old) with a body mass index equal or greater than the 97th percentile for the age and sex (male) of the subject, without any dysfunction or metabolic problem. The participants were divided into two groups - the E group (physical exercise program) and the E+D group (physical exercise program plus a low calorie diet). Metabolic parameters were evaluated (TC, HDL, LDL, TG, glucose, insulin, Systolic Blood Pressure, and Diastolic Blood Pressure), allowing the metabolic syndrome index to be calculated. Changes were observed in LDL-C (effect sizes = -3.19 and -2.28) and in the LDL-C/HDL-C ratio (effect sizes = -3.02 and -1.16) in the E and E+D groups, respectively. The prevalence of metabolic syndrome and obesity was completely removed only in the E group (100% norisk and non-obese subjects - exercise program (with or without diet) seems not to negatively affect the cardiovascular profile, suggesting that the program provides benefits and fosters healthy habits that can be maintained over time, preventing the development of metabolic syndrome.

    To examine whether chronic physical aggression (CPA) in adulthood can be epigenetically programmed early in life due to exposure to early-life adversity. Literature search of public databases such as PubMed/MEDLINE and Scopus. Children/adolescents susceptible for CPA and exposed to early-life abuse fail to efficiently cope with stress that in turn results in the development of CPA later in life. This phenomenon was observed in humans and animal models of aggression. The susceptibility to aggression is a complex trait that is regulated by the interaction between environmental and genetic factors. Epigenetic mechanisms mediate this interaction. Subjects exposed to stress early in life exhibited long-term epigenetic programming that can influence their behaviour in adulthood. This programming affects expression of many genes not only in the brain but also in other systems such as neuroendocrine and immune. The propensity to adult CPA behaviour in subjects experienced to early-life adversity is mediated by epigenetic programming that involves long-term systemic epigenetic alterations in a whole genome.

  5. Three-Dimensional Physical and Optical Characteristics of Aerosols over Central China from Long-Term CALIPSO and HYSPLIT Data

    Full Text Available Aerosols greatly influence global and regional atmospheric systems, and human life. However, a comprehensive understanding of the source regions and three-dimensional (3D characteristics of aerosol transport over central China is yet to be achieved. Thus, we investigate the 3D macroscopic, optical, physical, and transport properties of the aerosols over central China based on the March 2007 to February 2016 data obtained from the Cloud–Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO mission and the hybrid single-particle Lagrangian integrated trajectory (HYSPLIT model. Our results showed that approximately 60% of the aerosols distributed over central China originated from local areas, whereas non-locally produced aerosols constituted approximately 40%. Anthropogenic aerosols constituted the majority of the aerosol pollutants (69% that mainly distributed less than 2.0 km above mean sea level. Natural aerosols, which are mainly composed of dust, accounted for 31% of the total aerosols, and usually existed at an altitude higher than that of anthropogenic aerosols. Aerosol particles distributed in the near surface were smaller and more spherical than those distributed above 2.0 km. Aerosol optical depth (AOD and the particulate depolarization ratio displayed decreasing trends, with a total decrease of 0.11 and 0.016 from March 2007 to February 2016, respectively. These phenomena indicate that during the study period, the extinction properties of aerosols decreased, and the degree of sphericity in aerosol particles increased. Moreover, the annual anthropogenic and natural AOD demonstrated decreasing trends, with a total decrease of 0.07 and 0.04, respectively. This study may benefit the evaluation of the effects of the 3D properties of aerosols on regional climates.

    Our main objective in the current study was to evaluate the long-term effectiveness (12 months from baseline) of I Move (a web-based computer tailored physical activity intervention, based on self-determination theory and motivational interviewing). To this end, we compared I Move to a web-based computer tailored physical activity intervention based on traditional health behavior theories (Active Plus), and to a no-intervention control group. As a secondary objective, the present study aimed to identify participant characteristics that moderate the long term effects of I Move and Active Plus. A randomized controlled trial was conducted, comparing three research conditions: 1) the I Move condition, participants in this condition received I Move; 2) the Active Plus condition, participants in this condition received Active Plus; 3) the control condition; participants in this condition received no intervention and were placed on a waiting list. Main outcome measures were weekly minutes of moderate to vigorous physical activity and weekly days with minimal 30 min of physical activity. All measurements were taken by web-based questionnaires via the study website. Intervention effects were analyzed using multilevel linear regression analyses. At 12 months from baseline, I Move was found to be effective in increasing weekly minutes of moderate to vigorous physical activity (ES = .13), while Active Plus was not. In contrast, Active Plus was found to be effective in increasing weekly days with ≥ 30 min PA at 12 months (ES = .11), while I Move was not. No moderators of the effects of I Move were found. The results suggest that web-based computer tailored physical activity interventions might best include elements based on both self-determination theory/motivational interviewing and traditional health behavioral theories. To be more precise, it is arguable that the focus of the theoretical foundations, used in new web-based PA interventions should depend on the

  7. Who Becomes a Physics Major? A Long-term Longitudinal Study Examining the Roles of Pre-college Beliefs about Physics and Learning Physics, Interest, and Academic Achievement

    In this paper, we examine the correlation between students' beliefs upon entering college and their likelihood of continuing on to become a physics major. Since 2004, we have collected CLASS survey and self-reported level-of-interest responses from students in the first-term, introductory calculus-based physics course (N>2500). Here, we conduct a retrospective analysis of students' incoming CLASS scores and level of interest, comparing those students who go on to become physics majors with those who do not. We find the incoming CLASS scores and reported interest of these future physics majors to be substantially higher than the class average, indicating that these students enter their first college course already having quite expert-like beliefs. The comparative differences are much smaller for grades, SAT score, and university predicted-GPA.

    Forest fires can affect many soil properties and this fact is deeply connected with fire severity, intensity, soil type and many others factors. Aggregate stability (AS) indicates the soil structure resilience in response to external mechanical forces. AS is one of the factors that strongly affect on soil erodibility and infiltration. This property can be used as an indicator of the state of the soil structure and physical stability. The aim of this study is to analyze the soil AS of a determined area that suffered a wildfire in 1994 and compare them with a control area with the same characteristics. The study area is located in the Cadiretes Massif, in the northernmost zone of the Catalan Coastal Ranges, northeast Spain, at an altitude of around 190 - 250 m.a.m.s.l. The Cadiretes Massif is predominantly granite, although soils developed over Paleozoic metamorphic rocks such as schist and slates can also be found. In some areas metamorphic features underlie this relief. The massif is covered by dense Mediterranean vegetation, e.g. Quercus suber, Arbutus unedo, Erica arborea, and in some places Pinus pinaster plantations are found. This area receives about 700 - 800 mm of annual rainfall, with a fairly marked seasonal variability. The maximum is registered in autumn. Summer temperatures often surpass 25°C, while in winter temperatures are generally mild. The predominant soil type in Cadiretes is classified as a Lithic Xerept, with a 15 cm deep sandy-loam A horizon. In the control forest area, this horizon is protected by a 3 cm deep O horizon of moder humus. Three areas with different burnt intensity were identified in 1994 and they are the same plots that were chosen to sample in 2012. The 4 plots (Low intensity, Medium Intensity, High Intensity and Control) had the same orientation (S) and slope (5%). The TDI (Ten Drop Impact) test, that simulates rainfall impact on aggregates, was used to measure AS in the laboratory. Twenty samples were collected per plot. Ten

    Negative effects of restraint use have been well-documented. However, the prevalence of restraints use has been high in long-term care facilities in Hong Kong compared with other countries and this goes against the basic principles of ethical and compassionate care for older people. The present study aimed to review the change in the prevalence of physical and chemical restraint use in long-term care facilities (LTCFs) over a period of 11 years in Hong Kong and to identify the major factors associated with their use. This is an observational study with data obtained from the Hong Kong Longitudinal Study on LTCF Residents between 2005 and 2015. Trained assessors (nurses, social workers, and therapists) used the Minimum Data Set Resident Assessment Instrument to collect the data from 10 residential LTCFs. Physical restraint was defined as the use of any of the following: full bedside rails on all open sides of bed, other types of bedside rails used, trunk restraint, limb restraint, or the use of chair to prevent rising during the past 7 days. Chemical restraint was defined as the use of any of the following medications: antipsychotic, antianxiety, or hypnotic agents during past 7 days, excluding elder residents with a diagnosis of psychiatric illness. Annual prevalence of restraint use over 11 years and factors that were associated with the use of physical and chemical restraints. We analyzed the data for 2896 older people (978 male individuals, mean age = 83.3 years). Between 2005 and 2015, the prevalence of restraint use was as follows: physical restraint use increased from 52.7% to 70.2%; chemical restraint use increased from 15.9% to 21.78%; and either physical or chemical restraint use increased from 57.9% to 75.7%. Physical restraint use was independently associated with older age, impaired activities of daily living or cognitive function, bowel and bladder incontinence, dementia, and negative mood. Chemical restraint use was independently associated

    Aging is associated with compromised executive control functions. Several lines of evidence point to beneficial effects of physical activity on cognition which indicate that regular physical activity may counteract the age-related decline of some executive functions. Here, we investigate the effects of lifelong physical activity (about 50 years) on interference processing in two matched groups of 20 physically high active and 20 low active healthy older men using event-related potentials (ERPs). In a low interference block of the Stroop task, participants had to indicate the meaning of color-words, while color was either compatible or incompatible with the meaning. In the high interference block, participants were asked to respond according to the ink color of the word and to ignore its meaning. Physically active seniors showed faster reaction times, lower individual variability in reaction times, and higher accuracy compared to low active seniors, particularly in the high interference block. This result was confirmed in the classic paper-and-pencil version of the Stroop task showing higher interference score in the low active than high active individuals. ERPs revealed a shorter latency of the P2 and generally more negative amplitudes of the fronto-central N2 and N450 components in the high active group compared to the low active group. The amount of interference was negatively correlated with objectively measured fitness and self-reported physical activity. The positive effect of physical fitness on interference processing in the behavioral data was related to N2 and N450 amplitudes. Taken together, this suggests that seniors reporting long-term physical activity may exhibit generally enhanced activity in the frontal cortex which enables more efficient interference resolution in the Stroop task.

    The objective of this study was to systematically review the effectiveness of different types of regular leisure-time physical activities and pooled the effect sizes of those activities on long-term glycemic control in people with type 2 diabetes compared with routine care. This review included randomized controlled trials from 1960 to May 2014. A total of 10 Chinese and English databases were searched, following selection and critical appraisal, 18 randomized controlled trials with 915 participants were included. The standardized mean difference was reported as the summary statistic for the overall effect size in a random effects model. The results indicated yoga was the most effective in lowering glycated haemoglobin A1c (HbA1c) levels. Meta-analysis also revealed that the decrease in HbA1c levels of the subjects who took part in regular leisure-time physical activities was 0.60% more than that of control group participants. A higher frequency of regular leisure-time physical activities was found to be more effective in reducing HbA1c levels. The results of this review provide evidence of the benefits associated with regular leisure-time physical activities compared with routine care for lowering HbA1c levels in people with type 2 diabetes.

    Jatropha curcas L. is an important biofuel plant with excellent tolerance of barren environments. However, studies on the regulatory mechanisms that operate in this plant in response to nitrogen (N) shortage are scarce. In this study, genome-wide transcriptional profiles of the roots and leaves of 8-week old physic nut seedlings were analyzed after 2 and 16 days of N starvation. Enrichment results showed that genes associated with N metabolism, processing and regulation of RNA, and transport predominated among those showing alterations in expression. Genes encoding transporter families underwent major changes in expression in both roots and leaves; in particular, those with roles in ammonia, amino acid and peptide transport were generally up-regulated after long-term starvation, while AQUAPORIN genes, whose products function in osmoregulation, were down-regulated. We also found that ASPARA-GINASE B1 and SARCOSINE OXIDASE genes were up-regulated in roots and leaves after 2 and 16 d N starvation. Genes associated with ubiquitination-mediated protein degradation were significantly up-regulated. In addition, genes in the JA biosynthesis pathway were strongly activated while expression of those in GA signaling was inhibited in leaves. We showed that four major classes of genes, those with roles in N uptake, N reutilization, C/N ratio balance, and cell structure and synthesis, were particularly influenced by long-term N limitation. Our discoveries may offer clues to the molecular mechanisms that regulate N reallocation and reutilization so as to maintain or increase plant performance even under adverse environmental conditions.

    The purpose of this qualitative study was to explore how physical and social environments influence spouses' opportunities to maintain relationships when visiting a partner with dementia living in long-term care. Interviews with 15 spouses whose partners lived in long-term care facilities for persons with dementia, observations of physical environments and participant observations were conducted. The results showed how finding a place for spouses to connect in the long-term care facility was important in maintaining relationships. Access to individual rooms was an important feature that enabled connections throughout the phases of dementia, whereas common areas appeared more difficult to use because small spaces limited private interactions. Health personnel were important in sustaining spouses' abilities to maintain their relationships in long-term care facilities for persons with dementia. © The Author(s) 2016.

    Full Text Available BACKGROUND: The pathophysiological mechanisms underlining constipation are incompletely understood, but prolonged bed rest is commonly considered a relevant determinant. AIMS: Our primary aim was to study the effect of long-term physical inactivity on determining a new onset of constipation. Secondary aim were the evaluation of changes in stool frequency, bowel function and symptoms induced by this prolonged physical inactivity. METHODS: Ten healthy men underwent a 7-day run-in followed by 35-day study of experimentally-controlled bed rest. The study was sponsored by the Italian Space Agency. The onset of constipation was evaluated according to Rome III criteria for functional constipation. Abdominal bloating, flatulence, pain and urgency were assessed by a 100mm Visual Analog Scales and bowel function by adjectival scales (Bristol Stool Form Scale, ease of passage of stool and sense of incomplete evacuation. Daily measurements of bowel movements was summarized on a weekly score. Pre and post bed rest Quality of Life (SF-36, general health (Goldberg's General Health and depression mood (Zung scale questionnaires were administered. RESULTS: New onset of functional constipation fulfilling Rome III criteria was found in 60% (6/10 of participants (p=0.03. The score of flatulence significantly increased whilst the stool frequency significantly decreased during the week-by-week comparisons period (repeated-measures ANOVA, p=0.02 and p=0.001, respectively. Stool consistency and bowel symptoms were not influenced by prolonged physical inactivity. In addition, no significant changes were observed in general health, in mood state and in quality of life at the end of bed rest. CONCLUSIONS: Our results provide evidence that prolonged physical inactivity is relevant etiology in functional constipation in healthy individuals. The common clinical suggestion of early mobilization in bedridden patients is supported as well.

    Growing cacao (Theobroma cacao L.) in an agroforestry system generates a productive use of the land, preserves the best conditions for physical, chemical and biological properties of tropical soils, and plays an important role in improving cacao production and fertility of degraded tropical soils. The aim of this study was to evaluate the impact of two long term agroforestry systems of cacao management on soil physical and chemical properties in an area originally inhabited by 30 years old native secondary forest (SF). The two agroforestry systems adapted were: improved natural agroforestry system (INAS) where trees without economic value were selectively removed to provide 50% shade and improved traditional agroforestry system (ITAS) where all native trees were cut and burnt in the location. For evaluation of the changes of soil physical and chemical properties with time due to the imposed cacao management systems, plots of 10 cacao genotypes (ICS95, UF613, CCN51, ICT1112, ICT1026, ICT2162, ICT2171, ICT2142, H35, U30) and one plot with a spontaneous hybrid were selected. Soil samples were taken at 0-20, 20-40 and 40-60 cm depths before the installation of the management systems (2004), and then followed at two years intervals. Bulk density, porosity, field capacity and wilting point varied significantly during the years of assessment in the different soil depths and under the systems assessed. Soil pH, CEC, exchangeable Mg and sum of the bases were higher in the INAS than the ITAS. In both systems, SOM, Ext. P, K and Fe, exch. K, Mg and Al+H decreased with years of cultivation; these changes were more evident in the 0-20 cm soil depth. Overall improvement of SOM and soil nutrient status was much higher in the ITAS than INAS. The levels of physical and chemical properties of soil under cacao genotypes showed a marked difference in both systems.

    A sedentary lifestyle and increased consumption of energy dense food have become more common in many parts of the world. The aim of this study was to study long term effects on body composition after a four week intervention with fast food based hyper-alimentation and limited physical activity in young normal weight subjects. Eighteen subjects, mean age 26 (6.6) years, increased their energy intake with in average 70% and physical activity were not to exceed 5000 steps/day. Body composition was measured by Dual energy x-ray (DXA) at baseline, after the intervention and after 12 months. A matched control group was also included. ANOVA and Student's paired and unpaired t-test were used. During the intervention body weight increased with 6.4 (2.8) kg and DXA measurements showed increases of both fat free mass and fat mass. Six months after the intervention the subjects had lost most of the weight gain, - 4.7 (3.1) kg. Twelve months after the intervention body weight had increased with 1.5 (2.4) kg compared to baseline (p = 0.018). DXA measurements at 12 months showed unchanged fat free mass compared to baseline but higher fat mass, + 1.4 (1.9) kg (p = 0.01). After 2.5 years the increase of body weight was 3.1 (4.0) kg (p = 0.01) while there was no change in controls compared to baseline, + 0.1(2.5) kg (p = 0.88). One year after a short term intervention with increased fast food based hyper-alimentation there was an increase of fat mass but unchanged fat free mass. As the change of fat mass was larger than expected from prospective epidemiological studies and as there was no increase of body weight in controls it raises the issue whether there is a long-term effect to increase fat mass of a short period of hyper-alimentation.

    Full Text Available BACKGROUND: Child sexual abuse is considered a modifiable risk factor for mental disorders across the life course. However the long-term consequences of other forms of child maltreatment have not yet been systematically examined. The aim of this study was to summarise the evidence relating to the possible relationship between child physical abuse, emotional abuse, and neglect, and subsequent mental and physical health outcomes. METHODS AND FINDINGS: A systematic review was conducted using the Medline, EMBASE, and PsycINFO electronic databases up to 26 June 2012. Published cohort, cross-sectional, and case-control studies that examined non-sexual child maltreatment as a risk factor for loss of health were included. All meta-analyses were based on quality-effects models. Out of 285 articles assessed for eligibility, 124 studies satisfied the pre-determined inclusion criteria for meta-analysis. Statistically significant associations were observed between physical abuse, emotional abuse, and neglect and depressive disorders (physical abuse [odds ratio (OR = 1.54; 95% CI 1.16-2.04], emotional abuse [OR = 3.06; 95% CI 2.43-3.85], and neglect [OR = 2.11; 95% CI 1.61-2.77]; drug use (physical abuse [OR = 1.92; 95% CI 1.67-2.20], emotional abuse [OR = 1.41; 95% CI 1.11-1.79], and neglect [OR = 1.36; 95% CI 1.21-1.54]; suicide attempts (physical abuse [OR = 3.40; 95% CI 2.17-5.32], emotional abuse [OR = 3.37; 95% CI 2.44-4.67], and neglect [OR = 1.95; 95% CI 1.13-3.37]; and sexually transmitted infections and risky sexual behaviour (physical abuse [OR = 1.78; 95% CI 1.50-2.10], emotional abuse [OR = 1.75; 95% CI 1.49-2.04], and neglect [OR = 1.57; 95% CI 1.39-1.78]. Evidence for causality was assessed using Bradford Hill criteria. While suggestive evidence exists for a relationship between maltreatment and chronic diseases and lifestyle risk factors, more research is required to confirm these relationships.

    The prevalence of physical chronic or long-term conditions in adolescents aged 10-24 years is rising. Mobile phone and tablet mobile technologies featuring software program apps are widely used by these adolescents and their healthy peers for social networking or gaming. Apps are also used in health care to support personal condition management and they have considerable potential in this context. There is a growing body of literature on app use in health contexts, thereby making a systematic review of their effectiveness very timely. To systematically review the literature on the effectiveness of mobile apps designed to support adolescents' management of their physical chronic or long-term conditions. We conducted a review of the English-language literature published since 2003 in five relevant bibliographical databases using key search terms. Two independent reviewers screened titles and abstracts using data extraction and quality assessment tools. The search returned 1120 hits. Of the 19 eligible full-text papers, four met our review criteria, reporting one pilot randomized controlled trial and three pretest/post-test studies. Samples ranged from 4 to 18 participants, with a combined sample of 46 participants. The apps reported were targeted at type 1 diabetes, asthma, and cancer. Two papers provided data for calculating effect size. Heterogeneity in terms of study design, reported outcomes, follow-up times, participants' ages, and health conditions prevented meta-analyses. There was variation in whether adolescents received guidance in using the app or were solely responsible for navigating the app. Three studies reported some level of patient involvement in app design, development, and/or evaluation. Health professional involvement in the modelling stages of apps was reported in all studies, although it was not always clear whether specific clinical (as opposed to academic) expertise in working with adolescents was represented. The dearth of studies and the

    Lifestyle recommendations for cancer survivors are warranted to improve survival. In this study, we aimed to examine the association of total physical activity, different types of physical activity, hours of sleeping at day and night, and hours spent watching television (TV) with all-cause mortality in long-term colorectal cancer (CRC) survivors. We assessed physical activity in 1376 CRC survivors (44% women; median age, 69 years) at median 6 years after CRC diagnosis using a validated questionnaire. Multivariable-adjusted Cox regression models were used to estimate hazard ratios (HRs) for all-cause mortality according to categories of physical activities, sleep duration, and TV watching. During a median follow-up time of 7 years, 200 participants had died. Higher total physical activity was significantly associated with lower all-cause mortality (HR: 0.53; 95% CI: 0.36-0.80, 4th vs. 1st quartile). Specifically, sports, walking, and gardening showed a significant inverse association with all-cause mortality (HR: 0.34; 95% CI: 0.20-0.59, HR: 0.65; 95% CI: 0.43-1.00, and HR: 0.62; 95% CI: 0.42-0.91, respectively for highest versus lowest category). Individuals with ≥2 h of sleep during the day had a significantly increased risk of all-cause mortality compared to individuals with no sleep at day (HR: 2.22; 95% CI: 1.43-3.44). TV viewing of ≥4 h per day displayed a significant 45% (95% CI: 1.02-2.06) higher risk of dying compared to ≤2 h per day of watching TV. Physical activity was inversely related to all-cause mortality; specific activity types might be primarily responsible for this association. More hours of sleep during the day and a higher amount of TV viewing were each associated with higher all-cause mortality. Based on available evidence, it is reasonable to recommend CRC survivors to engage in regular physical activity.

    Although physical activity modulates the hypothalamic-pituitary-ovarian axis, the few studies that have investigated whether physical activity is associated with age at natural menopause have yielded mixed results. We set out to determine whether physical activity is associated with the timing of natural menopause in a large cohort of California women overall and by smoking history. We investigated the association between long-term physical activity (h/wk/y) and age at natural menopause among 97,945 women in the California Teachers Study. Multivariable Cox proportional hazards regression methods were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). The impact of cigarette smoking (never smoker, former light smoker, former heavy smoker, current light smoker, and current heavy smoker) as an effect modifier was evaluated. In a multivariable model adjusted for body mass index at age 18 years, age at menarche, race/ethnicity, and age at first full-term pregnancy, increased physical activity was statistically significantly associated with older age at natural menopause (P(trend) = 0.005). Higher body mass index at age 18 years (P(trend) = 0.0003) and older age at menarche (P(trend) = 0.0003) were also associated with older age at natural menopause. Hispanic ethnicity (vs non-Hispanic whites; HR, 1.17; 95% CI, 1.09-1.26), current smokers (vs never smokers; HR, 1.68; 95% CI, 1.60-1.75 for current light smokers; HR, 1.38; 95% CI, 1.33-1.44 for current heavy smokers), and older age at first full-term pregnancy (HR(≥29, 2+ full-term pregnancies) vs HR(menopause. Upon stratification by smoking history, increased physical activity was statistically significantly associated with older age at natural menopause among heavy smokers only (HR(highest quartile) vs HR(lowest quartile), 0.88; 95% CI, 0.81-0.97; P(trend) = 0.02 for former heavy smokers; HR(highest quartile) vs HR(lowest quartile), 0.89; 95% CI, 0.80-0.99; P(trend) = 0.04 for current heavy

    Subiculum is an important structure of the hippocampal formation and plays an imperative role in spatial learning and memory functions. We have demonstrated earlier the cognitive impairment following bilateral ventral subicular lesion (VSL) in rats. We found that short term exposure to enriched environment (EE) did not help to reverse the spatial memory deficits in water maze task suggesting the need for an appropriate enriched paradigm towards the recovery of spatial memory. In the present study, the efficacy of long term exposure of VSL rats to combination paradigm of environmental enrichment (EE), physical exercise and 18 C.W. diet (Combination Therapy - CT) in reversing the spatial memory deficits in Morris water maze task has been studied. Ibotenate lesioning of ventral subiculum produced significant impairment of performance in the Morris water maze and reduced the hippocampal neurogenesis in rats. Post lesion exposure to C.T. restored the hippocampal neurogenesis and improved the spatial memory functions in VSL rats. Our study supports the hypothesis that the combination paradigm is critical towards the development of an enhanced behavioral and cognitive experience especially in conditions of CNS insults and the associated cognitive dysfunctions.

    Full Text Available Introduction: Several sports demand an early start into long-term athlete development (LTAD because peak performances are achieved at a relatively young age (e.g., gymnastics. However, the challenging combination of high training volumes and academic demands may impede youth athletes' cognitive and academic performances. Thus, the aims of this study were to examine the effects of a 1-year sport-specific training and/or physical education on physical fitness, body composition, cognitive and academic performances in youth athletes and their non-athletic peers.Methods: Overall, 45 prepubertal fourth graders from a German elite sport school were enrolled in this study. Participating children were either youth athletes from an elite sports class (n = 20, age 9.5 ± 0.5 years or age-matched peers from a regular class (n = 25, age 9.6 ± 0.6 years. Over the 1-year intervention period, the elite sports class conducted physical education and sport-specific training (i.e., gymnastics, swimming, soccer, bicycle motocross [BMX] during school time while the regular class attended physical education only. Of note, BMX is a specialized form of cycling that is performed on motocross tracks and affords high technical skills. Before and after intervention, tests were performed for the assessment of physical fitness (speed [20-m sprint], agility [star agility run], muscle power [standing long jump], flexibility [stand-and-reach], endurance [6-min-run], balance [single-leg stance], body composition (e.g., muscle mass, cognitive (d2-test and academic performance (reading [ELFE 1–6], writing [HSP 4–5], calculating [DEMAT 4]. In addition, grades in German, English, Mathematics, and physical education were documented.Results: At baseline, youth athletes showed better physical fitness performances (p < 0.05; d = 0.70–2.16, less relative body fat mass, more relative skeletal muscle mass (p < 0.01; d = 1.62–1.84, and similar cognitive and academic achievements

    The U.S. Department of Energy's Energy Information Administration (EIA), and its predecessor organizations, has published projections of U.S. energy production, consumption, distribution and prices annually for over 30 years. A natural issue to raise in evaluating the projections is an assessment of their accuracy compared to eventual outcomes. A related issue is the determination of the sources of 'error' in the projections that are due to differences between the actual versus realized values of the associated assumptions. One way to do this would be to run the computer-based model from which the projections are derived at the time the projected values are realized, using actual rather than assumed values for model assumptions; and, compare these results to the original projections. For long term forecasts, this approach would require that the model's software and hardware configuration be archived and available for many years, possibly decades, into the future. Such archival creates many practical problems; and, in general, it is not being done. This paper reports on an alternative approach for evaluating the projections. In the alternative approach, the model is run many times for cases in which important assumptions are changed individually and in combinations. A database is assembled from the solutions and a regression analysis is conducted for each important projected variable with the associated assumptions chosen as exogenous variables. When actual data are eventually available, the regression results are then used to estimate the sources of the differences in the projections of the endogenous variables compared to their eventual outcomes. The results presented here are for residential and commercial sector natural gas and electricity consumption. (author)

  12. Long term wet spent nuclear fuel storage

    1987-04-01

    The meeting showed that there is continuing confidence in the use of wet storage for spent nuclear fuel and that long-term wet storage of fuel clad in zirconium alloys can be readily achieved. The importance of maintaining good water chemistry has been identified. The long-term wet storage behaviour of sensitized stainless steel clad fuel involves, as yet, some uncertainties. However, great reliance will be placed on long-term wet storage of spent fuel into the future. The following topics were treated to some extent: Oxidation of the external surface of fuel clad, rod consolidation, radiation protection, optimum methods of treating spent fuel storage water, physical radiation effects, and the behaviour of spent fuel assemblies of long-term wet storage conditions. A number of papers on national experience are included

    Full text: The radiation protection problem is mainly important with its relation with potential radioactivity threat to society and environment. Therefore, development of nuclear science in Uzbekistan since foundation of the Institute of Nuclear Physic (INP) is directly related to radiation protection of the personnel, population and environment. One of the major tasks highlighted in this report, importance of complex approach to the radiation protection and security, is worth of mentioning. Development of such an approach allows creation of a concept to predict the radiation situation and transition to radiation monitoring around the research nuclear centre. The aim of this complex approach to the solution of the radiation protection task is to find the methods for making predictions and managing the radiation situation around the nuclear centre. Complex approach to this research implies integration of theoretical and experimental activities. Theoretical studies involve primarily radiation prediction models. Experimental works are, on one hand, the data to approve the theoretical models, the obtained empirical parameters, and, on the other hand, information on the radiation situation for its forecasting. Lack of reliable information on the radioactivity level creates various rumours and is the major reason for radiophobia. The aim of this report is to present realistic information on the radioactivity level at the INP AS RU site and at the surrounding area, which is based on long-term measurements provided by the radiation protection department. In this work the following results of the research are presented: -total beta and gamma-activity of herbs and soil; - specific activity of waters (waste, underground, and surface); - activity of the air aerosols; - activity of the atmospheric precipitations; - background at the site of the INP, at the sanitary-protection area and observation area.

    2014-01-01

    Infrastructure projects, given their long life, require long term financing. The main sources of long term financings are insurance and pension funds who seek long term investments with low credit risk. However, in India household financial savings are mainly invested in bank deposits. Insurance and pension funds account for only a small percentage of household financial savings. In addition most infrastructure projects do not qualify for investment by insurance and pension funds because of t...

    To determine whether the benefit on cardiovascular risk factors (CVRF) persists 5 years after an intensive intervention in lifestyle (LS) that lasted 2 years, in patients with hyperfibrinogenaemia and moderate or high cardiovascular risk. multicentre prospective observational study. 13 Primary Care Centres in Barcelona and Baix Llobregat. A total of 300 patients who completed the EFAP study (146 intervention group, 154 control group). The EFAP study, conducted on patients with normal cholesterol and elevated fibrinogen showed that lifestyle interventions are effective in reducing CVRF. After the EFAP study, the 2 groups followed the usual controls, and re-assessed after 5 years. Age, gender, cardiovascular diseases (CVD) (diabetes, dyslipidaemia, hypertension, obesity), laboratory parameters (fibrinogen, glucose, full blood count, cholesterol, triglycerides), blood pressure, weight, height, body mass index (BMI), tobacco and alcohol use, REGICOR. At 5 years, the intervention group had a lower abdominal circumference (98 and 101cm, respectively, P=.043), a lower weight (76.30 and 75.04kg, respectively, P<.001), and BMI (29.5 and 30.97kg/m 2 , P=.018). Fibrinogen level was lower in the intervention group (330.33 and 320.27 mg/dl respectively, P < .001), and REGICOR risk was also lower in the intervention group (5.65 and 5.59 respectively, P < .06). The benefit of an intensive intervention in LS for 2 years to reduce CVRF persists at 5 years, but decreases its intensity over time. It is recommended to repeat the interventions periodically to maintain the beneficial effect on LS. Copyright © 2017. Publicado por Elsevier España, S.L.U.

However, the potential clinical effects and toxicities are still controversial.Methods: Here, 107 patients with biopsy-proven locally advanced NPC between March 2004 and January 2011 were enrolled in the retrospective study. Among them, 54 patients received IMRT-SIB, and 53 patients received IMRT-CF. Subsequently, overall survival (OS, 5-year progression-free survival (PFS, 5-year locoregional recurrence-free survival (LRFS, and relevant toxicities were analyzed.Results: In the present study, all patients completed the treatment, and the overall median follow-up time was 80 months (range: 8–126 months. The 5-year OS analysis revealed no significant difference between the IMRT-SIB and IMRT-CF groups (80.9% vs 80.5%, P=0.568. In addition, there were also no significant between-group differences in 5-year PFS (73.3% vs 74.4%, P=0.773 and 5-year LRFS (88.1% vs 90.8%, P=0.903. Notably, the dose to critical organs (spinal cord, brainstem, and parotid gland in patients treated by IMRT-CF was significantly lower than that in patients treated by IMRT-SIB (all P<0.05.Conclusion: Both IMRT-SIB and IMRT-CF techniques are effective in treating locally advanced NPC, with similar OS, PFS, and LRFS. However, IMRT-CF has more advantages than IMRT-SIB in protecting spinal cord, brainstem, and parotid gland from acute and late toxicities, such as xerostomia. Further prospective study is warranted to confirm our findings.Keywords: intensity

    Monitoring of artificial radionuclides in fishery products started in late 1950's and has over half a century history in Japan. Fisheries Agency (FA), Fisheries Research Agency (FRA) and prefectural organizations have been conducting the monitoring. The intensive monitoring of radioactive material in fishery products started in the late of March 2011 immediately after the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident for the coastal area faced to the Pacific Ocean in the eastern area of Japan and for the offshore area. The purpose of this monitoring is to avoid the distribution of fishery products containing radioactive cesium in concentration over the Japanese standard limit (Cs-134+Cs-137: 100 Bq/kg). Japanese monitoring data are opened to public on the FA's and FRA's web page. In this study, we resume the results of intensive monitoring started in 2011 and show the temporal change of concentration of radioactive cesium in fishery product. In Fukushima Prefecture, the ratio of samples exceeding the Japanese standard limit shows a steadily decreasing trend from 53% at Mar.- Jun. 2011 to below 3% at Jul. - Sep. 2013. In other prefectures, the ratio was 6.5% at Mar.- Jun. 2011 and fell gradually, and it has been below to 1% at Jul. - Sep. 2013. In presentation, we show the results of monitoring conducted in the coastal area and deeper water around Japan from long gamma ray measurements with ashed samples by high purified germanium gamma spectrometry.

    Long-term physical activity may affect risk of cognitive impairment but few studies have examined later life cognition in relation to intensity of life-long physical activity. We examined the associations between the intensity of long-term recreational physical activity and neuropsychological functioning in 90 healthy postmenopausal women on tests found to be useful in the early identification of dementia. Information was collected about their participation in strenuous and moderate activities between high school and menopause. Summary measures of long-term strenuous and moderate activity were constructed for each participant. All analyses were adjusted for relevant covariates. The six linear regression analyses showed significant positive associations between moderate activity and Wechsler Adult Intelligence Scale Revised (WAIS-R), Digit Span backward, WAIS-R Digit Symbol, and Trail Making Test Part B. Significant negative relationships were found between strenuous activity and Rey Auditory Verbal Learning Test delayed verbal recall, Complex Figure Test delayed visual memory, WAIS-R Digit Span backward, category fluency, and WAIS-R Digit Symbol. The associations found in the present study suggest that while moderate activity may be protective, long-term strenuous activity before menopause may lower cognitive performance later in life. These results support further investigation of the effects of life-long exercise intensity on cognition in later life.

  6. Long term radiotoxicity

    2001-01-01

    A major issue to secure the development of nuclear energy in future is the radioactive waste minimization, both inside the fuel cycle and in a deep geological storage. The aim of this paper is to establish the physical principles which provide an inherent minimization of the radioactive wastes. A new concept is introduced to characterize the radiotoxicity associated to various nuclei families in equilibrium state. The analysis shows the potential of evolutionary nuclear systems, mostly based on known technologies and the potential of more futuristic systems, like accelerator-driven systems and Th-fuel cycle. Several groups of the toxicity sources are object of the studies: Actinides as a part of the nuclear fuel which is remaining unusable after irradiation in nuclear power plants; long-lived fission products as the inevitable result of nuclear energy production; Lanthanides as an important part of fission products which separation from Actinides is technologically difficult because of similar chemical properties

    Full Text Available Background: The International Classification of Functioning, Disability and Health (ICF is recognised as the common language in disability research. However, personal factors in the ICF are not explicitly coded because of cultural differences that influence physical activity (PA participation. The ICF suggests using fitness as a personal factor, as well as other psychological assets. Intentions may serve as such psychological assets and studies on the antecedents to intentions which prompts PA behaviours is lacking in adolescent long term illness or disability (LTID populations. Objective: The purpose of this study was to report how ICF personal factors can influence participation in PA. Perceived fitness (FIT, global self-esteem (GSE, and PA intentions (INT are hypothesised to positively predict PA behaviours among adolescents with LTID after controlling for age. Methods: The data from Finnish 13 and 15 years old adolescents from the self-reported Health Behaviour in School-aged Children study from 2002 and 2010 were pooled. Those with LTID as stated by a medical doctor were included (N = 1,059. Serial mediation with ordinary least squares path analysis was used. Boys and girls were separately analysed, FIT was the independent variable, GSE and INT as mediators, and age controlled moderate-to-vigorous PA (MVPA the dependent variable. Bias-corrected bootstrap confidence intervals were used to test for significance of the direct and indirect paths. Results: FIT was positively related to GSE and INT for boys and girls. Furthermore, INT were positively related to MVPA for boys and girls. These relationships were statistically significant. Therefore, INT can be seen to mediate the relationship between FIT and MVPA after controlling for age. GSE also acted as a statistically significant mediator for boys, between FIT and INT. Therefore serial mediation was presented with boy's MVPA, whereas in the girl's model, only INT mediated FIT and MVPA

    Objective: To compare the long-term efficacy between two radiochemotherapy regimens for locally advanced nasopharyngeal carcinoma (NPC): intensity-modulated radiotherapy with concurrent chemotherapy (CCRT) versus neoadjuvant chemotherapy (NACT) followed by CCRT. Methods: A retrospective analysis was performed on the clinical data of 278 patients with locally advanced NPC who were admitted to our hospital from 2001 to 2008. Of the 278 patients, 133 received CCRT, and 145 received NACT followed by CCRT (NACT + CCRT). Results: The follow-up rate was 96.6%. The 5-year overall survival (OS),distant metastasis-free survival (DMFS), recurrence-free survival (RFS), and progression-free survival (PFS) were 78.1%, 78.0%, 90.6%, and 72.0%, respectively. There were no significant differences between the CCRT group and NACT + CCRT group in 5-year OS (79.9% vs. 76.4%, P=0.443), DMFS (77.1% vs. 78.9%, P=0.972), RFS (91.6% vs. 89.8%, P=0.475), and PFS (71.6% vs. 72.2%, P=0.731). Subgroup analysis showed that compared with CCRT, NACT + CCRT did not significantly improve 5-year RFS in T 3-4 N 0-1 patients (90.7% vs. 86.9%, P=0.376) and did not significantly improve 5-year DMFS in patients with advanced N-stage disease (57.6% vs. 69.7%, P=0.275). There were significantly higher numbers of individuals with neutropenia,decrease in hemoglobin, and upper gastrointestinal reactions in patients treated with NACT + CCRT than in those treated with CCRT (100 vs. 52, P=0.000; 64 vs. 35, P=0.010; 90 vs. 63, P=0.044). Conclusions: Compared with CCRT,NACT + CCRT does not significantly improve the prognosis in patients with locally advanced NPC and leads to significant increases in grade ≥ 3 toxicities (neutropenia, decrease in hemoglobin, and upper gastrointestinal reactions). The role of NACT in the treatment of locally advanced NPC needs further study. (authors)

    Purpose: To determine the potential association between genitourinary (GU) toxicity and planning dose–volume parameters for GU pelvic structures after high-dose intensity modulated radiation therapy in localized prostate cancer patients. Methods and Materials: A total of 268 patients who underwent intensity modulated radiation therapy to a prescribed dose of 86.4 Gy in 48 fractions during June 2004-December 2008 were evaluated with the International Prostate Symptom Score (IPSS) questionnaire. Dose–volume histograms of the whole bladder, bladder wall, urethra, and bladder trigone were analyzed. The primary endpoint for GU toxicity was an IPSS sum increase ≥10 points over baseline. Univariate and multivariate analyses were done by the Kaplan-Meier method and Cox proportional hazard models, respectively. Results: Median follow-up was 5 years (range, 3-7.7 years). Thirty-nine patients experienced an IPSS sum increase ≥10 during follow-up; 84% remained event free at 5 years. After univariate analysis, lower baseline IPSS sum (P=.006), the V90 of the trigone (P=.006), and the maximal dose to the trigone (P=.003) were significantly associated with an IPSS sum increase ≥10. After multivariate analysis, lower baseline IPSS sum (P=.009) and increased maximal dose to the trigone (P=.005) remained significantly associated. Seventy-two patients had both a lower baseline IPSS sum and a higher maximal dose to the trigone and were defined as high risk, and 68 patients had both a higher baseline IPSS sum and a lower maximal dose to the trigone and were defined as low risk for development of an IPSS sum increase ≥10. Twenty-one of 72 high-risk patients (29%) and 5 of 68 low-risk patients (7%) experienced an IPSS sum increase ≥10 (P=.001; odds ratio 5.19). Conclusions: The application of hot spots to the bladder trigone was significantly associated with relevant changes in IPSS during follow-up. Reduction of radiation dose to the lower bladder and specifically the

    To investigate the long-term (2-15 years) functional outcome of children and young adults who received an early intensive neurorehabilitation programme (EINP) after a prolonged period of unconsciousness due to severe brain injury; to differentiate between traumatic brain injury (TBI) and non-traumatic brain injury (nTBI); and to compare the results on two different outcome scales: the Disability Rating Scale (DRS) and the Glasgow Outcome Scale Extended (GOSE). One hundred and forty-five patients, who were admitted to EINP between December 1987 and January 2001. The Post-Acute Level of Consciousness scale (PALOC-s), the DRS, including categorized scores (DRScat), and the GOSE. The long-term functional level of 90 patients could be determined, of whom 25 were deceased. The mean DRS-score of the surviving patients was 6.8 (SD = 6.6); the mean score on the GOSE was 4.5 (SD = 1.7). There was a significant difference in the outcome amongst traumatic and non-traumatic patients (t88 = 4.21; p GOSE was high (Spearman rho = 0.85; p GOSE (Spearman rho = 0.81; p GOSE. Especially item 7 of the DRS, measuring functional independence, showed considerable variance in discriminating between different outcome levels. More patients with TBI than expected reached a (semi-) independent level of functioning, indicating a possible effect of EINP. Patients suffering from nTBI did not demonstrate these outcome levels. Only a few patients stayed in a vegetative state for more than a couple of years. In this cohort of severe brain-injured young people, the DRS offered the best investigative possibilities for long-term level of functioning.

    Lung function decline is a well-recognized complication following allogeneic SCT (allo-SCT). Reduced-intensity conditioning (RIC) and in vivo T-cell depletion by administration of antithymocyte globulin (ATG) may have a protective role in the occurrence of late pulmonary complications. This retrospective study reported the evolution of lung function parameters within the first 2 years after allo-SCT in a population receiving the same RIC regimen that included fludarabine and i.v. BU in combination with low-dose ATG. The median follow-up was 35.2 months. With a median age of 59 years at the time of transplant, at 2 years, the cumulative incidences of non-relapse mortality was as low as 9.7%. The cumulative incidence of relapse was 33%. At 2 years, the cumulative incidences of extensive chronic GVHD (cGVHD) and of pulmonary cGVHD were 23.1% and 1.9%, respectively. The cumulative incidences of airflow obstruction and restrictive pattern were 3.8% and 9.6%, respectively. Moreover, forced expiratory volume (FEV1), forced vital capacity (FVC) and FEV1/FVC ratio remained stable from baseline up to 2 years post transplantation (P=0.26, P=0.27 and P=0.07, respectively). These results correspond favorably with the results obtained with other RIC regimens not incorporating ATG, and suggest that ATG may have a protective pulmonary role after allo-SCT.

    Full Text Available Parkinson’s disease (PD is a neurodegenerative disease in which gait and balance disturbances are relevant symptoms that respond poorly to pharmacological treatment. The aim of this study was to investigate whether a 4-week inpatient multidisciplinary intensive rehabilitation treatment (MIRT is effective in improving balance and gait and whether improvements persist at a one-year followup. We studied 20 PD inpatients (stage 3 Hoehn-Yahr who underwent a MIRT. Outcome measures were UPDRS items for balance (30, falls (13, and walk (29, Berg Balance Scale, six-minute walking test, Timed Up and Go Test, and Comfortable-Fast gait speeds. Patients were evaluated at admission, at the end of the 4-week treatment, and at a 1-year followup. Pharmacological therapy was unchanged during MIRT and follow-up. All outcome measures improved significantly at the end of treatment. At 1-year follow-up control, UPDRS walk and Comfortable-Fast gait speeds still maintained better values with respect to admission (P=0.009, P=0.03, and P=0.02, resp., while the remaining scales did not differ significantly. Our results demonstrate that the MIRT was effective in improving balance and gait and that the improvement in gait performances was partially maintained also after 1 year.

    The aim of the study was to evaluate the efficacy of tattoo removal treatments using the 1064-nm Q-switched (QS) Nd:YAG laser. Today, QS lasers appear to be the most common, effective, and safest methods to treat unwanted markings. A total of 64 patients with 75 unwanted tattoos were enrolled in the study. Tattoo clearance was evaluated according to the color intensity - concentration of pigment: group I (34) - black; group II (41) - gray. Consideration included methods of tattooing and tattoo techniques. In group I, after the first treatment session the median of clearance was 30% (10-50%), while in group II, the median was 50% (40-70%). After the second treatment session, median in group I increased to 40% (30-50%). Median of group II increased to 70% (50-80%). The highest number of treatment in group I was 7. After that, the median grew to 75%, while the highest amount of treatment in group II was 5 and a median of 90% was achieved. Effects were dependent upon the amount of ink deposited in the tissue. Old amateur tattoos and tattoos containing small quantities of ink (technique: shading and lines) demonstrated the quickest and the most efficacious results. Tattoos with large quantities of ink, obtained by filling, required the greatest number of treatment sessions. The final outcome in tattoo clearing can only be assessed following treatment completion, which may in some cases take 2-3 years. Presumably, in some cases, complete clearance is impossible. © 2015 Wiley Periodicals, Inc.

    The purpose of this study is to compare the treatment outcome of different radiation doses of elective neck irradiation (ENI) in nasopharyngeal carcinoma (NPC) patients treated with intensity-modulated radiotherapy (IMRT).In total, 504 patients with nondisseminated NPC who underwent magnetic resonance imaging before radical IMRT between 2000 and 2008 were retrospectively reviewed. The patients were classified into 2 groups based on the ENI dose: low ENI when the ENI dose was 46 Gy (n = 446) and high ENI when the ENI doses were 50 to 60 Gy (n = 58). All the patients in both the groups received a median dose of 72 Gy to the gross tumor and involved nodes. The fraction size was 2 Gy per fraction. Matching was performed between low ENI and high ENI in a 2:1 ratio, and the matching criteria were N-stage, T-stage, treatment modality, pathology classification, sex, and age.The median follow-up for all patients was 63.5 months. In all patients, the 5-year progression-free survival (PFS), local control (LC), regional control (RC), distant metastasis-free survival (DMFS), overall survival (OS), and cancer-specific survival (CSS) for low ENI and high ENI patients were 69.0% and 63.2% (P = 0.331), 89.0% and 83.9% (P = 0.235), 90.1% and 85.2% (P = 0.246), 86.8% and 76.6% (P = 0.056), 77.5% and 80.8% (P = 0.926), and 84.4% and 82.5% (P = 0.237), respectively. In the matched-pair analysis, the 5-year PFS, LC, RC, DMFS, OS, and CSS for matched low ENI and high ENI patients were 74.1% and 63.2% (P = 0.134), 92.0% and 83.9% (P = 0.152), 90.1% and 85.2% (P = 0.356), 86.2% and 76.6% (P = 0.125), 87.0% and 80.8% (P = 0.102), and 88.6% and 82.5% (P = 0.080), respectively. In the multivariable analysis for all patients, the ENI group was not a significant factor for PFS, LC, RC, DMFS, OS, and CSS.A low ENI dose of 46 Gy in 23 fractions is feasible in NPC patients treated with IMRT, and this concept should be validated in the

    Purpose: Although 3-dimensional conformal radiotherapy (3D-CRT) is the worldwide standard for the treatment of esophageal cancer, intensity modulated radiotherapy (IMRT) improves dose conformality and reduces the radiation exposure to normal tissues. We hypothesized that the dosimetric advantages of IMRT should translate to substantive benefits in clinical outcomes compared with 3D-CRT. Methods and Materials: An analysis was performed of 676 nonrandomized patients (3D-CRT, n=413; IMRT, n=263) with stage Ib-IVa (American Joint Committee on Cancer 2002) esophageal cancers treated with chemoradiotherapy at a single institution from 1998-2008. An inverse probability of treatment weighting and inclusion of propensity score (treatment probability) as a covariate were used to compare overall survival time, interval to local failure, and interval to distant metastasis, while accounting for the effects of other clinically relevant covariates. The propensity scores were estimated using logistic regression analysis. Results: A fitted multivariate inverse probability weighted-adjusted Cox model showed that the overall survival time was significantly associated with several well-known prognostic factors, along with the treatment modality (IMRT vs 3D-CRT, hazard ratio 0.72, P<.001). Compared with IMRT, 3D-CRT patients had a significantly greater risk of dying (72.6% vs 52.9%, inverse probability of treatment weighting, log-rank test, P<.0001) and of locoregional recurrence (P=.0038). No difference was seen in cancer-specific mortality (Gray's test, P=.86) or distant metastasis (P=.99) between the 2 groups. An increased cumulative incidence of cardiac death was seen in the 3D-CRT group (P=.049), but most deaths were undocumented (5-year estimate, 11.7% in 3D-CRT vs 5.4% in IMRT group, Gray's test, P=.0029). Conclusions: Overall survival, locoregional control, and noncancer-related death were significantly better after IMRT than after 3D-CRT. Although these results need

    This thesis is a study of the effect of high intensity lasers on atoms, free electrons and the generation of X-rays from solid density plasmas. The laser produced 50 milli Joule 180 femto sec pulses at 5 Hz. This translates to a maximum intensity of 5 x 10 18 W/cm 2 . At such high fields the AC stark shifts of atoms placed at the focus is much greater than the ionization energy. The characteristics of multiphoton ionization of atoms in intense laser fields was studied by angle resolved photoelectron spectroscopy. Free electrons placed in high intensity laser fields lead to harmonic generation. This phenomenon of Nonlinear Compton Scattering was theoretically investigated. Also, when these high intensity pulses are focused on solids a hot plasma is created. This plasma is a bright source of a short X-ray pulse. The pulse-width of X-rays from these solid density plasmas was measured by time-resolved X-ray spectroscopy

    To investigate the relationship between emotional status, cold-dry environment and long-term immune responses to the stressors, and the potential pathological mechanisms between causative factors of abnormal Savda syndrome (ASS) and the susceptibility to disease; thus to clarify the ASS, and secondly to identify the optimal ASS animal model for further studies on traditional Uighur therapeutical formulations. Sixty mice were randomly and equally divided into 4 groups: control and 3 stress groups. The cold-dry environment was applied by keeping the mice in a climatic chamber. The emotional stress was induced by the application of the repeated electric foot-shocks in the electric foot-shock apparatus. The mice of the combined stress group underwent the repeated electric foot-shock treatment before being housed in the climatic chamber. The experimental routine was repeated for 21 days. In order to look into endocrine and immune stress responses, ELISA was used to determine the serum levels of the hormones corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH), Beta-endorphin (β-END) and corticosterone (CORT), of the cytokines interleukin 2 (IL-2), interleukin 6 (IL-6), interferon-gamma (INF-γ) and tumor necrosis factor-alpha (TNF-α), and of the immunoglobulins immunoglobulin A (IgA), immunoglobulin M (IgM) and immunoglobulin G (IgG). Lymphocyte subsets were analyzed in duplicate in order to determine differences in the T cell ratio. In the cold-dry environment group, the serum levels of CRH, ACTH and CORT were significantly higher than those of the control group, whereas serum β-END was not found significantly different. In both the repeated electric foot-shock group as well as in the combined stress group the serum levels of CRH, ACTH, β-END and CORT were significantly higher. Compared to the control animals, the serum concentration of INF-γ was significantly lower in all three different stress groups. The serum level of IL-2 was decreased in

    Evaluates landslide hazards in the Turow brown coal mine in the area of a safety pillar of the Neisse river. Physical and mechanical properties of the following types of rocks from the pillar were investigated under laboratory conditions: cohesive Quaternary strata, clay layers adjacent to the coal seams and separating the seams, weathered and disintegrated granite, basalt and tuff (detritus). Rock samples were tested under conditions of tri-axial stresses, with natural water pore pressure, samples with a natural structure without artificial consolidation. The tests showed intensive fluctuations of rock properties. Nonhomogeneity of the samples and structural disturbances were determined. The tests showed the existence of landslide hazards in the Neisse river area. Recommendations for further investigations are made. 3 refs.

    IMPORTANCE A growing proportion of US smokers now smoke fewer than 10 cigarettes per day (CPD), and that proportion will likely rise in the future. The health effects of smoking only a few CPD over one’s lifetime are less understood than are the effects of heavier smoking, although many smokers believe that their level is modest. OBJECTIVE To evaluate the associations of long-term smoking of fewer than 1 or 1 to 10 CPD (low intensity) with all-cause and cause-specific mortality compared with never smoking cigarettes. DESIGN, SETTING, AND PARTICIPANTS Prospective cohort study of 290 215 adults in the National Institutes of Health–AARP (formerly known as the American Association of Retired Persons) Diet and Health Study who were aged 59 to 82 years in calendar years 2004–2005 (baseline). Data were gathered with a questionnaire assessing lifetime cigarette smoking history. Hazard ratios (HRs) and 95% CIs were determined for all-cause mortality and cause-specific mortality through the end of 2011. Hazard ratios and 95% CIs were estimated using Cox proportional hazards regression models using age as the underlying time metric and adjusted for sex, race/ethnicity, educational level, physical activity, and alcohol intake. Data analysis was conducted from December 15, 2015, to September 30, 2016. EXPOSURES Current and historical smoking intensity during 9 previous age periods (from smoked fewer than 1 or 1 to 10 CPD at baseline reported smoking substantially higher numbers of CPD earlier in their lives. Nevertheless, 159 (9.1%) and 1493 (22.5%) of these individuals reported consistently smoking fewer than 1 or 1 to 10 CPD in each age period that they smoked, respectively. Relative to never smokers, consistent smokers of fewer than 1 CPD (HR, 1.64; 95% CI, 1.07–2.51) and 1 to 10 CPD (HR, 1.87; 95% CI, 1.64–2.13) had a higher all-cause mortality risk. Associations were similar in women and men for all-cause mortality and were observed across a range of smoking

    Among the diverse applications of spintronics, security for internet-of-things (IoT) devices is one of the most important. A physically unclonable function (PUF) with a spin device (spin transfer torque magnetoresistive random access memory, STT-MRAM) is presented. Oxide tunnel barrier breakdown is used to realize long-term stability for PUFs. A secure PUF has been confirmed by evaluating the Hamming distance of a 32-bit STT-MRAM-PUF fabricated using 65 nm CMOS technology.

    This systematic review aims to report the effectiveness of interventions based on exercise and/or physical environment for reducing falls in cognitively impaired older adults living in long-term care facilities. In July 2014, a literature search was conducted using main databases and specialised sources. Randomised controlled trials assessing the effectiveness of fall prevention interventions, which used exercise or physical environment among elderly people with cognitive impairment living in long-term care facilities, were selected. Two independent reviewers checked the eligibility of the studies, and evaluated their methodological quality. If it was adequate, data were gathered. Fourteen studies with 3,539 participants using exercise and/or physical environment by a single or combined approach were included. The data gathered from studies that used both interventions showed a significant reduction in fall rate. Further research is needed to demonstrate the effectiveness of those interventions for preventing falls in the elderly with cognitive impairment living in long-term care establishments.

    Injuries can counter the beneficial effects of sports participation at a young age if a child or adolescent is unable to continue to participate because of residual effects of injury. This paper reviews current knowledge in the field of long-term health outcomes of youth sports injuries to evaluate the evidence regarding children dropping out of sport due to injury, physeal injuries and growth disturbance, studies of injuries affecting the spine and knee of young and former athletes and surgical outcome of anterior cruciate ligament (ACL) reconstruction in children. Studies of dropping out of sport due to injury are limited primarily to gymnasts and implicate such injuries as ACL rupture and osteochondritis dissecans of the elbow joint in the early retirement of young athletes. Although most physeal injuries resolve with treatment and rest, there is evidence of disturbed physeal growth as a result of injury. Radiological findings implicate the effects of intense physical loading and injury in the development of spinal pathology and back pain during the growth of youth athletes; however, long-term effects are unclear. Follow-up studies of young athletes and adults indicate a high risk of osteoarthritis after meniscus or ACL injury. Prospective cohort studies with a follow-up into adulthood are needed to clarify the long-term health outcomes of youth sports injuries. Important to this research is meticulous documentation of injuries on injury report forms that include age-appropriate designations of the type of injury and accurate determination of exposure-based injury rates.

    There is growing evidence that exercise induced experience dependent plasticity may foster structural and functional recovery following brain injury. We examined the efficacy of exercise training for neural and cognitive recovery in long-term pediatric brain tumor survivors treated with radiation. We conducted a controlled clinical trial with crossover of exercise training (vs. no training) in a volunteer sample of 28 children treated with cranial radiation for brain tumors (mean age = 11.5 yrs.; mean time since diagnosis = 5.7 yrs). The endpoints were anatomical T1 MRI data and multiple behavioral outcomes presenting a broader analysis of structural MRI data across the entire brain. This included an analysis of changes in cortical thickness and brain volume using automated, user unbiased approaches. A series of general linear mixed effects models evaluating the effects of exercise training on cortical thickness were performed in a voxel and vertex-wise manner, as well as for specific regions of interest. In exploratory analyses, we evaluated the relationship between changes in cortical thickness after exercise with multiple behavioral outcomes, as well as the relation of these measures at baseline. Exercise was associated with increases in cortical thickness within the right pre and postcentral gyri. Other notable areas of increased thickness related to training were present in the left pre and postcentral gyri, left temporal pole, left superior temporal gyrus, and left parahippocampal gyrus. Further, we observed that compared to a separate cohort of healthy children, participants displayed multiple areas with a significantly thinner cortex prior to training and fewer differences following training, indicating amelioration of anatomical deficits. Partial least squares analysis (PLS) revealed specific patterns of relations between cortical thickness and various behavioral outcomes both after training and at baseline. Overall, our results indicate that

The endpoints were anatomical T1 MRI data and multiple behavioral outcomes presenting a broader analysis of structural MRI data across the entire brain. This included an analysis of changes in cortical thickness and brain volume using automated, user unbiased approaches. A series of general linear mixed effects models evaluating the effects of exercise training on cortical thickness were performed in a voxel and vertex-wise manner, as well as for specific regions of interest. In exploratory analyses, we evaluated the relationship between changes in cortical thickness after exercise with multiple behavioral outcomes, as well as the relation of these measures at baseline.Exercise was associated with increases in cortical thickness within the right pre and postcentral gyri. Other notable areas of increased thickness related to training were present in the left pre and postcentral gyri, left temporal pole, left superior temporal gyrus, and left parahippocampal gyrus. Further, we observed that compared to a separate cohort of healthy children, participants displayed multiple areas with a significantly thinner cortex prior to training and fewer differences following training, indicating amelioration of anatomical deficits. Partial least squares analysis (PLS revealed specific patterns of relations between cortical thickness and various behavioral outcomes both after training and at baseline.Overall, our results

    Dementia is a progressive neurological disorder that causes a high degree of dependency. This dependency has been defined as an increased need for assistance due to deterioration in cognition and physical functioning, and changes in behavior. Highly dependent people with dementia are more likely to be institutionalized. To investigate the association between specific categories of physical dependency and the presence of neuropsychiatric symptoms in people with dementia admitted to a long-term care institution. A prospective observational cohort study. Home care and long-term care institutions in eight European countries. People with dementia living at home but at risk of institutionalization and recently institutionalized people with dementia. Baseline and 3-month follow-up interviews were performed between November, 2010 and April, 2012. The sample consisted of 116 recently institutionalized dementia sufferers and 949 people with dementia still living at home. Physical dependency was measured using the Katz Activity of Daily Living index, and neuropsychiatric symptoms were assessed through The Neuropsychiatric Inventory. Specific categories of dependency were analyzed by performing a logistic regression analysis. This followed examination of baseline characteristics to define the degree of physical dependency, as factors associated with institutionalization, and evaluation of the same characteristics at 3-month follow-up to detect changes in the degree of physical dependency and neuropsychiatric symptoms associated with recent admission to a long-term care institution. Toileting, dressing and continence dependency was higher in institutionalized people than in those receiving home-care. Delusion, hallucination, agitation, anxiety, apathy, motor-disturbances, night-time behavior and eating disorders were also worse in the institutionalized. Logistic regression analysis showed that independent factors significantly associated with being recently institutionalized

    Oral health is often overlooked in institutional elder care but may have an impact on general health and ability to communicate. We aimed to determine the factor associated with chewing and swallowing problems among long-term care residents in Taiwan. Staff nurses trained to evaluate oral health assessed 781 residents using relevant sections of the Minimum Data Set 2.1 for nursing homes (Chinese version), including the Cognitive Performance Scale, Index of Social Engagement, and Activities of Daily Living Scale. Individuals with chewing and swallowing problems (n = 345) tended to be women (odds ratio [OR] = 1.51, P = .019) in smaller facilities (OR = 4.18, P broken, loose, or carious teeth (OR = 1.74, P = .042); and with more frequently inflamed gums (OR = 2.72, P = .025) than residents without chewing and swallowing problems (n = 436). Residents' chewing and swallowing problems were significantly associated with parenteral/enteral intake, oral health status, nutritional status, concomitant disease and infection, cognitive function, and social engagement.

  12. Nuclear Energy, Long Term Requirements

    2006-01-01

    There are serious warnings about depletion of oil and gas and even more serious warnings about dangers of climate change caused by emission of carbon dioxide. Should developed countries be called to replace CO2 emitting energy sources as soon as possible, and the time available may not be longer then few decades, can nuclear energy answer the call and what are the requirements? Assuming optimistic contribution of renewable energy sources, can nuclear energy expand to several times present level in order to replace large part of fossil fuels use? Paper considers intermediate and long-term requirements. Future of nuclear power depends on satisfactory answers on several questions. First group of questions are those important for near and intermediate future. They deal with economics and safety of nuclear power stations in the first place. On the same time scale a generally accepted concept for radioactive waste disposal is also required. All these issues are in the focus of present research and development. Safer and more economical reactors are targets of international efforts in Generation IV and INPRO projects, but aiming further ahead these innovative projects are also addressing issues such as waste reduction and proliferation resistance. However, even assuming successful technical development of these projects, and there is no reason to doubt it, long term and large-scale nuclear power use is thereby not yet secured. If nuclear power is to play an essential role in the long-term future energy production and in reduction of CO2 emission, than several additional questions must be replied. These questions will deal with long-term nuclear fuel sufficiency, with necessary contribution of nuclear power in sectors of transport and industrial processes and with nuclear proliferation safety. This last issue is more political then technical, thus sometimes neglected by nuclear engineers, yet it will have essential role for the long-term prospects of nuclear power. The

    Strength and balance training (SBT) has remarkable health benefits, but little is known regarding exercise adherence in older adults. We examined the adherence to strength and balance training and determinants of adherence among ≥75 year old adults. 182 community-dwelling individuals (aged 75-98 years, 71% female) began group-based SBT as part of a population-based Geriatric Multidisciplinary Strategy for the Good Care of the Elderly study. Training was offered once a week for 2.3 years. Adherence was defined as the proportion of attended sessions relative to offered sessions. Participants were classified based on their adherence level into low (≤33.3%), moderate (33.4-66.5%) and high (≥66.6%) adherers. The mean length of training was 19 ± 9 months, and 68% continued participation for at least two years. The mean training adherence was 55 ± 29% for all participants and 18%, 53% and 82% for low, moderate and high adherers, respectively. High adherence was predicted by female sex; younger age; better cognition; independence in Instrumental Activities of Daily Living; higher knee extension strength; faster walking speed; and better performance on the Berg Balance Scale and Timed Up and Go tests. Poorer self-perceived health and the use of a walking aid were related to low adherence. Long-term continuation of training is possible for older community-dwelling adults, although poorer health and functional limitations affect training adherence. Our findings have implications for tailoring interventions and support for older adults to optimize their exercise adherence. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Lavie, J.M.

    1984-01-01

    In France, waste management, a sensitive issue in term of public opinion, is developing quickly, and due to twenty years of experience, is now reaching maturity. With the launching of the French nuclear programme, the use of radioactive sources in radiotherapy and industry, waste management has become an industrial activity. Waste management is an integrated system dealing with the wastes from their production to the long term disposal, including their identification, sortage, treatment, packaging, collection and transport. This system aims at guaranteing the protection of present and future populations with an available technology. In regard to their long term management, and the design of disposals, radioactive wastes are divided in three categories. This classification takes into account the different radioisotopes contained, their half life and their total activity. Presently short-lived wastes are stored in the shallowland disposal of the ''Centre de la Manche''. Set up within the French Atomic Energy Commission (CEA), the National Agency for waste management (ANDRA) is responsible within the framework of legislative and regulatory provisions for long term waste management in France [fr

    Simon, Steven L.; Bouville, Andre

    2016-01-01

    This paper revisits and reiterates the needs, purposes and requirements of bio-dosimetric assays for long-term dose and health risk assessments. While the most crucial need for bio-dosimetric assays is to guide medical response for radiation accidents, the value of such techniques for improving our understanding of radiation health risk by supporting epidemiological (long-term health risk) studies is significant. As new cohorts of exposed persons are identified and new health risk studies are undertaken with the hopes that studying the exposed will result in a deeper understanding of radiation risk, the value of reliable dose reconstruction is underscored. The ultimate application of biodosimetry in long-term health risk studies would be to completely replace model-based dose reconstruction-a complex suite of methods for retrospectively estimating dose that is commonly fraught with large uncertainties due to the absence of important exposure-related information, as well as imperfect models. While biodosimetry could potentially supplant model-based doses, there are numerous limitations of presently available techniques that constrain their widespread application in health risk research, including limited ability to assess doses received far in the past, high cost, great inter-individual variability, invasiveness, higher than preferred detection limits and the inability to assess internal dose (for the most part). These limitations prevent the extensive application of biodosimetry to large cohorts and should be considered a challenge to researchers to develop new and more flexible techniques that meet the demands of long-term health risk research. Events in recent years, e.g. the Fukushima reactor accident and the increased threat of nuclear terrorism, underscore that any event that results in significant radiation exposures of a group of people will also produce a much larger population, exposed at lower levels, but that likewise needs (or demands) an exposure

    Opioid addiction is associated with excess mortality, morbidities, and other adverse conditions. Guided by a life-course framework, we review the literature on the long-term course of opioid addiction in terms of use trajectories, transitions, and turning points, as well as other factors that facilitate recovery from addiction. Most long-term follow-up studies are based on heroin addicts recruited from treatment settings (mostly methadone maintenance treatment), many of whom are referred by the criminal justice system. Cumulative evidence indicates that opioid addiction is a chronic disorder with frequent relapses. Longer treatment retention is associated with a greater likelihood of abstinence, whereas incarceration is negatively related to subsequent abstinence. Over the long term, the mortality rate of opioid addicts (overdose being the most common cause) is about 6 to 20 times greater than that of the general population; among those who remain alive, the prevalence of stable abstinence from opioid use is low (less than 30% after 10-30 years of observation), and many continue to use alcohol and other drugs after ceasing to use opioids. Histories of sexual or physical abuse and comorbid mental disorders are associated with the persistence of opioid use, whereas family and social support, as well as employment, facilitates recovery. Maintaining opioid abstinence for at least five years substantially increases the likelihood of future stable abstinence. Recent advances in pharmacological treatment options (buprenorphine and naltrexone) include depot formulations offering longer duration of medication; their impact on the long-term course of opioid addiction remains to be assessed.

    Objective To clarify the impact of hearing aids on mental health, social engagement, cognitive function, and physical health outcomes in older adults with hearing impairment. Design We assessed hearing handicap (Hearing Handicap Inventory for the Elderly; HHIE-S), cognition (Mini Mental State Exam, Trail Making, Auditory Verbal Learning, Digit-Symbol Substitution, Verbal Fluency, incidence of cognitive impairment), physical health (SF-12 physical component, basic and instrumental activities of daily living, mortality), social engagement (hours per week spent in solitary activities) and mental health (SF-12 mental component) at baseline, 5 years prior to baseline, and 5 and 11 years after baseline. Study sample Community-dwelling older adults with hearing impairment (N=666) from the Epidemiology of Hearing Loss Study cohort. Results There were no significant differences between hearing aid users and non-users in cognitive, social engagement or mental health outcomes at any time point. Aided HHIE-S was significantly better than unaided HHIE-S. At 11 years hearing aid users had significantly better SF-12 physical health scores (46.2 versus 41.2; p=0.03). There was no difference in incidence of cognitive impairment or mortality. Conclusion There was no evidence that hearing aids promote cognitive function, mental health, or social engagement. Hearing aids may reduce hearing handicap and promote better physical health. PMID:26140300

    To examine the effect that physical activity delivered via two different versions of the Green Prescription (a primary care physical activity scripting program) had on depressive symptomatology and general mental health functioning over a 12-month period in non-depressed, low-active, community-dwelling older adults. Two hundred and twenty-five participants from the Healthy Steps study took part in the present study. Healthy Steps participants were randomized to receive either the standard time-based or a modified pedometer-based Green Prescription. Depression, mental health functioning and physical activity were measured at baseline, post-intervention (3 months post-baseline) and at the 9-month follow-up period. At post-intervention, a positive association was found between increases in leisure-time physical activity and total walking physical activity and a decrease in depressive symptomatology (within the non-depressed range of the GDS-15) and an increase in perceived mental health functioning, regardless of intervention allocation. These improvements were also evident at the follow-up period for participants in both intervention allocation groups. Our findings suggest that the standard time-based Green Prescription and a modified pedometer-based Green Prescription are both effective in maintaining and improving mental health in non-depressed, previously low-active older adults.

    To honor Tom Waters's work on emerging occupational health issues, we review the literature on physical along with chemical exposures and their impact on functional outcomes. Many occupations present the opportunity for exposure to multiple hazardous exposures, including both physical and chemical factors. However, little is known about how these different factors affect functional ability and injury. The goal of this review is to examine the relationships between these exposures, impairment of the neuromuscular and musculoskeletal systems, functional outcomes, and health problems with a focus on acute injury. Literature was identified using online databases, including PubMed, Ovid Medline, and Google Scholar. References from included articles were searched for additional relevant articles. This review documented the limited existing literature that discussed cognitive impairment and functional disorders via neurotoxicity for physical exposures (heat and repetitive loading) and chemical exposures (pesticides, volatile organic compounds [VOCs], and heavy metals). This review supports that workers are exposed to physical and chemical exposures that are associated with negative health effects, including functional impairment and injury. Innovation in exposure assessment with respect to quantifying the joint exposure to these different exposures is especially needed for developing risk assessment models and, ultimately, preventive measures. Along with physical exposures, chemical exposures need to be considered, alone and in combination, in assessing functional ability and occupationally related injuries. © 2016, Human Factors and Ergonomics Society.

    This study aimed to evaluate the physical frailty status of vulnerable older adults as classified in the Japanese LTCI system and to compare this with Fried's definition. A total of 444 older adults were classified based on the LTCI system as independent, vulnerable, or dependent, and 400 of these participants also fit Fried's criteria for not frail, pre-frail or frail. We evaluated their physical function with a 12 item physical function test. We derived a physical function score (PFS) from these 12 items and a principal component analysis was used to make comparisons. The receiver operating characteristic (ROC) curve analysis was performed to identify the sensitivity and specificity of the PFS cut-off points to distinguish the dependent category from the other categories. We found significant differences and a hierarchical order for the PFSs among the three groups of the LTCI system (the independent, 0.41 ± 0.54; the vulnerable, -0.40 ± 0.76; and the dependent, -1.49 ± 0.73) and of Fried's definition (not frail, 0.50 ± 0.51; pre frail, -0.11 ± 0.63; and frail, -1.25 ± 0.98). The optimal cut-off value (OCV) was -0.593. This study showed that the range of physical function of people considered frail category (pre-frail, vulnerable, and frail) is wide and overlapping. That is, the physical function of vulnerable older adults is worse than the pre-frail, but better than the frail. To better recognize older adults in need of greater support, the vulnerable should also receive assessment of their frailty status according to Fried's definition.

    We investigated the association of physical activity with survival for 601 Hispanic women and 682 non-Hispanic white women who participated in the population-based breast cancer case-control New Mexico Women's Health Study. We identified 240 deaths among cases diagnosed with a first primary invasive breast cancer between 1992 and 1994, and 88 deaths among controls. Follow-up extended through 2012 for cases and 2008 for controls. Multivariable hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards regression. Higher levels of total physical activity were inversely associated with all-cause mortality among Hispanic cases (Quartile (Q)4: HR = 0.55, 95% CI 0.31-0.99). A non-significant trend was observed for recreational activity in Hispanic cases also (Q4: HR = 0.50, 95% CI 0.23-1.09, p for trend = 0.08). No significant associations were noted for non-Hispanic white cases or for controls. The results suggest that increasing physical activity may be protective against mortality in Hispanic women with breast cancer, despite reporting lower levels of recreational activity than non-Hispanic white women or Hispanic controls. Public health programs in Hispanic communities should promote physical activity in women as a means of decreasing breast cancer risk and improving survival.

    Since stressful situations are considered risk factors for the development of depression and there are few studies evaluating prevention therapies for this disease, in the present study we evaluated the effect of previous physical exercise in animals subjected to chronic variable stress (CVS), an animal model of depression, on behavior tasks. We also investigated some parameters of oxidative stress and Na + , K + -ATPase activity, immunocontent and gene expression of alpha subunits in amygdala and hippocampus of rats. Young male rats were randomized into four study groups (control, exercised, stressed, exercised+stressed). The animals were subjected to controlled exercise treadmill for 20min,three times a week, for two months prior to submission to the CVS (40days). Results show that CVS impaired performance in inhibitory avoidance at 24h and 7days after training session. CVS induced oxidative stress, increasing reactive species, lipoperoxidation and protein damage, and decreasing the activity of antioxidant enzymes. The activity of Na + , K + -ATPase was decreased, but the immunocontents and gene expression of catalytic subunits were not altered. The previous physical exercise was able to improve performance in inhibitory avoidance at 24h after training; additionally, exercise prevented oxidative damage, but was unable to reverse completely the changes observed on the enzymatic activities. Our findings suggest that physical exercise during the developmental period may protect against aversive memory impairment and brain oxidative damage caused by chronic stress exposure later in life.

This study investigates a worksite health promotion programme with individually tailored advice in physical activity and nutrition and individual counselling to increase compliance with lifestyle recommendations and sustainability of a healthy lifestyle. Methods/Design The study is a pragmatic cluster randomised controlled trial with the worksite as the unit of randomisation. All workers will receive a standard worksite health promotion program. Additionally, the intervention group will receive access to an individual Health Portal consisting of four critical features: a computer-tailored advice, a monitoring function, a personal coach, and opportunities to contact professionals at request. Participants are employees working for companies in the Netherlands, being literate enough to read and understand simple Internet-based messages in the Dutch language. A questionnaire to assess primary outcomes (compliance with national recommendations on physical activity and on fruit and vegetable intake will take place at baseline and after 12 and 24 months. This questionnaire also assesses secondary outcomes including fat intake, self-efficacy and self-perceived barriers on physical activity and fruit and vegetable intake. Other secondary outcomes, including a cardiovascular risk profile and physical fitness, will be measured at baseline and after 24 months. Apart from the effect evaluation, a process evaluation will be carried out to gain insight into participation and adherence to the worksite health promotion programme.

    Alpine ski racing is known to be a sport with a high risk of injuries. Because most studies have focused mainly on top-level athletes and on traumatic injuries, limited research exists about injury risk factors among youth ski racers. The aim of this study was to determine the intrinsic risk factors (anthropometrics, biological maturity, physical fitness, racing technique) for injury among youth alpine ski racers. Study participants were 81 youth ski racers attending a ski boarding school (50 males, 31 females; 9–14 years). A prospective longitudinal cohort design was used to monitor sports-related risk factors over two seasons and traumatic (TI) and overuse injuries (OI). At the beginning of the study, anthropometric characteristics (body height, body weight, sitting height, body mass index); biological maturity [status age at peak height velocity (APHV)]; physical performance parameters related to jump coordination, maximal leg and core strength, explosive and reactive strength, balance and endurance; and ski racing technique were assessed. Z score transformations normalized the age groups. Multivariate binary logistic regression (dependent variable: injury yes/no) and multivariate linear regression analyses (dependent variable: injury severity in total days of absence from training) were calculated. T-tests and multivariate analyses of variance were used to reveal differences between injured and non-injured athletes and between injury severity groups. The level of significance was set to p jump contact time; and higher drop jump reactive strength index were at a lower injury risk or more vulnerable for fewer days of absence from training. However, significant differences between injured and non-injured athletes were only observed with respect to the drop jump reactive strength index. Regular documentation of anthropometric characteristics, biological maturity and physical fitness parameters is crucial to help to prevent injury in youth ski racing. The present

    Full Text Available Balanced and integrated use of organic and inorganic fertilizers may enhance the accumulation of soil organic matter and improves soil physical properties. A field experiment having randomized complete block design with four replications was conducted for 36 years at Punjab Agricultural University (PAU, Ludhiana, India to assess the effects of inorganic fertilizers and farmyard manure (FYM on soil organic carbon (SOC, soil physical properties and crop yields in a maize (Zea mays–wheat (Triticum aestivum rotation. Soil fertility management treatments included were non-treated control, 100% N, 50% NPK, 100% NP, 100% NPK, 150% NPK, 100% NPK + Zn, 100% NPK + W, 100% NPK (-S and 100% NPK + FYM. Soil pH, bulk density (BD, electrical conductivity (EC, cation exchange capacity, aggregate mean weight diameter (MWD and infiltration were measured 36 years after the initiation of experiment. Cumulative infiltration, infiltration rate and aggregate MWD were greater with integrated use of FYM along with 100% NPK compared to non-treated control. No significant differences were obtained among fertilizer treatments for BD and EC. The SOC pool was the lowest in control at 7.3 Mg ha−1 and increased to 11.6 Mg ha−1 with 100%NPK+FYM. Improved soil physical conditions and increase in SOC resulted in higher maize and wheat yields. Infiltration rate, aggregate MWD and crop yields were positively correlated with SOC. Continuous cropping and integrated use of organic and inorganic fertilizers increased soil C sequestration and crop yields. Balanced application of NPK fertilizers with FYM was best option for higher crop yields in maize–wheat rotation.

    Periodontal disease is a chronic infectious disease. Individuals with end-stage kidney disease (ESKD) experience impaired quality of life (QoL) and low oral health. This is the first comprehensive study which aimed to explore the link between periodontal disease and quality of life, assessed with the Short Form 36-Item Health Survey in hemodialysis patients. In total, 101 patients (57 females) with ESKD were recruited from two Romanian dialysis centers. Periodontal disease assessment included the measurement of periodontal disease index, with its three components: the gingival and periodontal index (GP), the bacterial plaque index (PI) and the calculus index (CI). For assessing QoL, we used the Short Form 36-Item Health Survey (SF-36), with its two components: physical component (PCS) and mental component (MCS). The mean age was 52.5 ± 14.3 years. The dialysis vintage was 6.7 ± 5.6 years. According to periodontal status, the mean value of GP was 4.0 ± 1.3, mean PI was 1.8 ± 0.9, and mean CI was 1.3 ± 0.7. Regarding the QoL, the means for PCS and MCS were 38.0 ± 17.3 and 45.0 ± 16.3, respectively. In univariate analysis, the physical and mental components of QoL were significantly associated with the gingival and periodontal index, the bacterial plaque index and the calculus index. In the multivariable linear regression, only the gingival and periodontal index remained significantly associated with physical component (β = -3.26, p = 0.04, 95% CI -6.39 to -0.13) and mental component (β = -5.57, p = 0.001, 95% CI -8.74 to -2.41) of QoL. Our study shows a high prevalence and severity of periodontal disease. The gingival and periodontal index was associated with low QoL, both on physical and on mental components.

    The Stroop colour word test (SCWT) has been widely used to assess changes in cognitive performance such as processing speed, selective attention and the degree of automaticity. Moreover, the SCWT has proven to be a valuable tool to assess neuronal plasticity that is coupled to improvement in performance in clinical populations. In a previous study, we showed impaired cognitive processing during SCWT along with reduced task-related activations in patients with fibromyalgia. In this study, we used SCWT and functional magnetic resonance imagingFMRI to investigate the effects of a 15-week physical exercise intervention on cognitive performance, task-related cortical activation and distraction-induced analgesia (DIA) in patients with fibromyalgia and healthy controls. The exercise intervention yielded reduced fibromyalgia symptoms, improved cognitive processing and increased task-related activation of amygdala, but no effect on DIA. Our results suggest beneficial effects of physical exercise on cognitive functioning in FM. © 2017 The Authors.

    500 and 69 male former elite athletes and 319 male controls completed a health questionnaire in 1985 and in 1995. Register data on the subjects were also collected. Subjects were aged 65 years or less and had no history of hypertension in 1985, and they had been healthy at the age of 20 years. The athletes were grouped into endurance and mixed sports (n = 386), and power sports (n = 183). The cumulative 10-year incidence of hypertension up to 1995 was significantly lower in the endurance and mixed sports group (23.6 %) compared to the power sports group (33.3 %) or the control group (32.0 %). The difference between the endurance and mixed sports group and the two other groups was still significant after adjustment for age, but not after further adjustment for body mass index, alcohol consumption, and later physical activity. However, the trend of reduced risk remained. In conclusion, a history of being an elite athlete in endurance or mixed sports predicts a lower risk of hypertension in working age men, while a history of being an elite athlete in power sports appears to confer no benefit. Later physical activity was also associated with lower risk.

    Full Text Available Americans over age 65 constitute a larger percentage of the population each year: from 14% in 2010 (40 million elderly to possibly 20% in 2030 (70 million elderly. In 2015, an estimated 66 million people provided care to the ill, disabled, and elderly in the United States. In 2000, according to the Centers for Disease Control and Prevention (CDC, 15 million Americans used some form of long-term care: adult day care, home health, nursing home, or hospice. In all, 13% of people over 85 years old, compared with 1% of those ages 65 to 74, live in nursing homes in the United States. Transitions of care, among these various levels of care, are common: Nursing home to hospital transfer, one of the best-studied transitions, occurs in more than 25% of nursing home residents per year. This article follows one patient through several levels of care.

    The purpose of this study was to compare the effects of 16-week group exercise program on the physical function (ie, strength, flexibility, and balance) and mental health (ie, self-esteem and depression) of older elderlyl women (>or=75 years old) compared with younger elderly women (Self-esteem (using Rosenberg's Self-esteem Questionnaire) and depressive symptoms (using Yesavage's Geriatric Depression Scale) were assessed. Two-way analysis of variance was used to examine the differences between the 2 age groups. The intervention program was effective in improving body strength, flexibility, static balance, and self-esteem, regardless of age. Furthermore, older elders receiving the intervention program demonstrated greater improvement in self-esteem than younger elders did, although there were intervention effects in both age groups. Elderly women can realize benefits from a group exercise program that can improve their functional ability and self-esteem, both important to cardiovascular health.

    In March 2001, the world's largest depictions of standing Buddha figures located in Bamiyan (Afghanistan) were destroyed during a campaign of the Taliban leadership against all non-Muslim heritage in the country. Bamiyan and its archaeological remains have been nominated a World Heritage also to commemorate the events of destruction the site has experienced over the centuries. More than fifteen years after the Giant Buddha figures turned into dust, the UNESCO Safeguarding campaign for the preservation of the Bamiyan World Heritage property has made considerable progress. Upon continued request by the local population and the national government, the international community is asked to contribute proposals for the future presentation of the physical remains including the options of reassembling the original fragments. The achievements and backlashes of the UNESCO campaign are discussed and a proposal is given, how virtual technology can contribute to the ongoing discussion regarding the future of the site. At a time when deliberate raids during military conflicts against heritage places have become commonplace, the Bamiyan case has become emblematic and is considered now a key turning point in the heritage community on the question, which roles reconstruction can have especially in the aftermath of conflict situations. It is argued that immersive virtual reality technologies offer the chance to investigate how values attributed to cultural heritage are produced and experienced among different stakeholder groups.

    Full Text Available Androgen replacement therapy (ART efficacy on late-onset hypogonadism (LOH has been widely investigated in Western countries; however, it remains controversial whether ART can improve health and prolong active lifestyles. We prospectively assessed long-term ART effects on the physical and mental statuses of aging men with LOH in Japan. The primary endpoint was health-related quality of life assessed by questionnaires. Secondary endpoints included glycemic control, lipid parameters, blood pressure, waist circumference, body composition, muscular strength, International Prostate Symptom Scores (IPSS, International Index of Erectile Function-5 (IIEF-5 scores, and serum prostate-specific antigen levels. Of the 1637 eligible volunteers, 334 patients > 40 years with LOH were randomly assigned to either the ART (n = 169 or control groups (n = 165. Fifty-two weeks after the initial treatment, ART significantly affected the role physical subdomain of the short form-36 health survey (SF-36 scale (P = 0.0318.

    A futuristic evaluation of mankind's potential long term future in space is presented. Progress in space will not be inhibited by shortages of the Earth's physical resources, since long term economic growth will be focused on ways to constrain industrial productivity by changing social values, management styles, or government competence. Future technological progress is likely to accelerate with an emphasis on international cooperation, making possible such large joint projects as lunar colonies or space stations on Mars. The long term future in space looks exceedingly bright even in relatively pessimistic scenarios. The principal driving forces will be technological progress, commercial and public-oriented satellites, space industrialization, space travel, and eventually space colonization.

    Although physical activity has been shown to contribute to long-term disease control and health in breast cancer survivors, a majority of breast cancer survivors do not meet physical activity guidelines. Past research has focused on promoting physical activity components for short-term breast cancer survivor benefits, but insufficient attention has been devoted to long-term outcomes and sustained exercise adherence. We are assessing a health coach intervention (iMOVE) that uses mobile technology to increase and sustain physical activity maintenance in initially inactive breast cancer survivors. This pilot randomized controlled trial (RCT) is an initial step in evaluating the iMOVE intervention and will inform development of a full-scale pragmatic RCT. We will enroll 107 physically inactive breast cancer survivors and randomly assign them to intervention or control groups at the University Health Network, a tertiary cancer care center in Toronto, Canada. Participants will be women (age 18 to 74 years) stratified by age (55 years and older/younger than 55 years) and adjuvant hormone therapy (AHT) exposure (AHT vs no AHT) following breast cancer treatment with no metastases or recurrence who report less than 60 minutes of preplanned physical activity per week. Both intervention and control groups receive the 12-week physical activity program with weekly group sessions and an individualized, progressive, home-based exercise program. The intervention group will additionally receive (1) 10 telephone-based health coaching sessions, (2) smartphone with data plan, if needed, (3) supportive health tracking software (Connected Wellness, NexJ Health Inc), and (4) a wearable step-counting device linked to a smartphone program.

    Full Text Available In this study, properties of limestone cement concrete containing different replacement levels of limestone powder were examined. It includes 0%, 5%, 10%, 15%, 20% and 25% of limestone powder as a partial replacement of cement. Silica fume was added incorporated with limestone powder in some mixes to enhance the concrete properties. Compressive strength, splitting tensile strength and modulus of elasticity were determined. Also, durability of limestone cement concrete with different C3A contents was examined. The weight loss, length change and cube compressive strength loss were measured for concrete attacked by 5% sodium sulfate using an accelerated test up to 525 days age. The corrosion resistance was measured through accelerated corrosion test using first crack time, cracking width and steel reinforcement weight loss. Consequently, for short and long term, the use of limestone up to 10% had not a significant reduction in concrete properties. It is not recommended to use blended limestone cement in case of sulfate attack. The use of limestone cement containing up to 25% limestone has insignificant effect on corrosion resistance before cracking.

    While the United States Supreme Court's Jackson v. Indiana decision and most state statutes mandate determinations of incompetent defendants' restoration probabilities, courts and forensic clinicians continue to lack empirical evidence to guide these determinations and do not yet have a consensus regarding whether and under what circumstances incompetent defendants are restorable. The evidence base concerning the restoration likelihood of those defendants who fail initial restoration efforts is even further diminished and has largely gone unstudied. In this study, we examined the disposition of a cohort of defendants who underwent long-term competence restoration efforts (greater than six months) and identified factors related to whether these defendants were able to attain restoration and adjudicative success. Approximately two-thirds (n = 52) of the 81 individuals undergoing extended restoration efforts were eventually deemed restored to competence. Lengths of hospitalization until successful restoration are presented with implications for the reasonable length of time that restoration efforts should persist. Older individuals were less likely to be restored and successfully adjudicated, and individuals with more severe charges and greater factual legal understanding were more likely to be restored and adjudicated. The significance of these findings for courts and forensic clinicians is discussed.

  17. Uranium ... long-term confidence

    1983-01-01

    Half way through 1983 the outlook for the world's uranium producers was far from bright if one takes a short term view. The readily accessible facts present a gloomy picture. The spot prices of uranium over the past few years decreased from a high of $42-$43/lb to a low of $17 in 1982. It now hovers between $23 and $24. the contract prices negotiated between producers and consumers are not so accessible but they do not reflect the spot price. The reasons why contractual uranium prices do not follow the usual dictates of supply and demand are related to the position in which uranium and associated power industries find themselves. There is public reaction with strong emotional overtones as well as much reduced expectations about the electric power needs of the world. Furthermore the supply of uranium is not guaranteed despite present over production. However the people in the industry, taking the medium- and long-term view, are not despondent

  18. Long-term corrosion studies

    1998-01-01

    The scope of this activity is to assess the long-term corrosion properties of metallic materials under consideration for fabricating waste package containers. Three classes of metals are to be assessed: corrosion resistant, intermediate corrosion resistant, and corrosion allowance. Corrosion properties to be evaluated are general, pitting and crevice corrosion, stress-corrosion cracking, and galvanic corrosion. The performance of these materials will be investigated under conditions that are considered relevant to the potential emplacement site. Testing in four aqueous solutions, and vapor phases above them, and at two temperatures are planned for this activity. (The environmental conditions, test metals, and matrix are described in detail in Section 3.0.) The purpose and objective of this activity is to obtain the kinetic and mechanistic information on degradation of metallic alloys currently being considered for waste package containers. This information will be used to provide assistance to (1) waste package design (metal barrier selection) (E-20-90 to E-20-92), (2) waste package performance assessment activities (SIP-PA-2), (3) model development (E-20-75 to E-20-89). and (4) repository license application

    There is limited information about long-term prognosis of ischemic stroke in young adults. Giving the potentially negative impact in physical, social, and emotional aspects of an ischemic stroke in young people, providing early accurate long-term prognostic information is very important in this clinical setting. Moreover, detection of factors associated with bad outcomes (death, recurrence, moderate-to-severe disability) help physicians in optimizing secondary prevention strategies. The prese...

    1999-01-01

    The quantum field theory in the presence of classical background electromagnetic field is reviewed giving a pedagogical introduction to the Feynman-Furry method of describing non-perturbative interactions with very strong electromagnetic fields. A particular emphasis is given to the case of the plane-wave electromagnetic field for which the charged particles' wave functions and propagators are presented. Some general features of quantum processes proceeding in the intense electromagnetic background are argued. The possibilities of searching new physics through the investigations of quantum phenomena induced by a strong electromagnetic environment are also discussed

    To determine the short- and long-term effectiveness of the application of Clinical Pilates in addition to physical therapy versus a physical therapy treatment alone in a population of postmenopausal women with chronic low back pain (CLBP). A single-blind randomized controlled trial with repeated measures and a follow-up period. One hundred and one patients were randomly allocated to a Pilates + physical therapy (PPT) group or to a physical therapy (PT) only group for six weeks. Pain and disability were measured by visual analog scale (VAS) and the Oswestry disability index respectively preintervention, after 6 weeks of treatment and after 1-year follow-up. There were significant differences between groups in pain and disability after 6 weeks of treatment, with better results in the PPT group with an effect size of d = 3.14 and d = 2.33 for pain and disability. After 1-year follow-up, only PPT group showed better results compared with baseline with an effect size of d = 2.49 and d = 4.98 for pain and disability. The results suggest that using Clinical Pilates in addition to physical therapy provides improved results on pain management and functional status for postmenopausal woman with CLBP and that its benefits still linger after one year. Chronic Low Back Pain could benefit from the Pilates practice in postmenopausal women. Improvement in pain and disability derived from CLBP seem to be maintained over time due to Pilates practice. Pilates constitutes a safe tool to be applied in older population with CLBP due to its ability to be adapted to every performance and physical level.

    This is an open randomized controlled trial. The objective of this study was to investigate the effects of a 16-week hybrid cycle versus handcycle exercise program on fitness and physical activity in inactive people with long-term spinal cord injury (SCI). The study was conducted in two rehabilitation centers with a specialized SCI unit. Twenty individuals (SCI⩾8 years) were randomly assigned to a hybrid cycle (voluntary arm exercise combined with functional electrical stimulation (FES)-induced leg exercise) or a handcycle group. During 16 weeks, both groups trained twice a week for 30 min at 65-75% heart rate reserve. Outcome measures obtained before, during and after the program were fitness (peak power output, peak oxygen consumption), submaximal VO2 and heart rate (HR), resting HR, wheelchair skill performance time score) and physical activity (distance travelled in wheelchair and Physical Activity Scale for Individuals with Physical Disabilities (PASIPD) score). Changes were examined using a two-factor mixed-measures analysis of variance. For all fitness parameters, except for submaximal VO2, no interaction effects were found. The hybrid cycle group showed a decrease in VO2 over time in contrast to the handcycle group (P=0.045). An overall reduction in HRrest (5±2 b.p.m.; P=0.03) and overall increase in PASIPD score (6.5±2.1; P=0.002) were found after 16 weeks of training. No overall training effects were found for the other fitness and activity outcome measures. In the current study, hybrid cycling and handcycling showed similar effects on fitness and physical activity, indicating that there seem to be no additional benefits of the FES-induced leg exercise over handcycle training alone.

    This document summarizes the work done in our three-year LDRD project titled 'Physics of Intense, High Energy Radiation Effects.' This LDRD is focused on electrical effects of ionizing radiation at high dose-rates. One major thrust throughout the project has been the radiation-induced conductivity (RIC) produced by the ionizing radiation. Another important consideration has been the electrical effect of dose-enhanced radiation. This transient effect can produce an electromagnetic pulse (EMP). The unifying theme of the project has been the dielectric function. This quantity contains much of the physics covered in this project. For example, the work on transient electrical effects in radiation-induced conductivity (RIC) has been a key focus for the work on the EMP effects. This physics in contained in the dielectric function, which can also be expressed as a conductivity. The transient defects created during a radiation event are also contained, in principle. The energy loss lead the hot electrons and holes is given by the stopping power of ionizing radiation. This information is given by the inverse dielectric function. Finally, the short time atomistic phenomena caused by ionizing radiation can also be considered to be contained within the dielectric function. During the LDRD, meetings about the work were held every week. These discussions involved theorists, experimentalists and engineers. These discussions branched out into the work done in other projects. For example, the work on EMP effects had influence on another project focused on such phenomena in gases. Furthermore, the physics of radiation detectors and radiation dosimeters was often discussed, and these discussions had impact on related projects. Some LDRD-related documents are now stored on a sharepoint site (https://sharepoint.sandia.gov/sites/LDRD-REMS/default.aspx).

    Type 1 diabetes (T1D) in children and young people is increasing worldwide with a particular increase in children under the age of 5 years. Fewer than one in six children and young people achieve glycosylated fraction of haemoglobin (HbA1c) values in the range identified as providing best future outcomes. There is an urgent need for clinic-based pragmatic, feasible and effective interventions that improve both glycaemic control and quality of life (QoL). The intervention offers both structured education, to ensure young people know what they need to know, and a delivery model designed to motivate self-management. To assess the feasibility of providing a clinic-based structured educational group programme incorporating psychological approaches to improve long-term glycaemic control, QoL and psychosocial functioning in a diverse range of young people. The study was a pragmatic, cluster randomised control trial with integral process and economic evaluation. Twenty-eight paediatric diabetes services across London, south-east England and the Midlands. Minimised by clinic size, age (paediatric or adolescent) and specialisation (district general hospital clinic or teaching hospital/tertiary clinic). Half of the sites were randomised to the intervention arm and half to the control arm. Allocation was concealed until after clinics had consented and the first participant was recruited. Where possible, families were blind to allocation until recruitment finished. Forty-three health-care practitioners (14 teams) were trained in the intervention. The study recruited 362 children aged 8-16 years, diagnosed with T1D for > 12 months, with a mean 12-month HbA1c level of ≥ 8.5%. Two 1-day workshops taught intervention delivery. A detailed manual and resources were provided. The intervention consists of four group education sessions led by a paediatric diabetes specialist nurse with another team member. The primary outcome was glycaemic control, assessed at the individual level

    This study examined long-term follow-up effects of participation in the HomeStyles RCT, using Social Cognitive Theory constructs, on physical activity cognitions, home environment, and lifestyle behavioral practices of families with preschool children (ages 2 to 5 years). Parents were systematically randomized to experimental or attention control group at baseline. Those completing all surveys that comprised of valid, reliable measures were the analytic sample (n = 61 experimental, n = 63 control; mean age 32.8 ± 5.9SD years). Repeated measures ANCOVA, controlling for prognostic variables (e.g., parent sex) revealed that variables assessing modeling of physical activity for children increased significantly (P ≤ .01) in both groups with no significant time by group effects. Paired t-tests indicated the experimental group's self-efficacy for keeping children's weight healthy and performing health promoting behaviors increased significantly over time whereas the control group did not but with no significant time by group effects. Self-regulation paired t-test findings indicated that total screentime the experimental group allowed children decreased significantly over time with no significant time by group effect. The value parents placed on physical activity for children increased over time in both groups with a significant time effect. The experimental group over time had significantly greater increases in the availability of physical activity space and supports inside the home than the control group. Improvements noted have the potential to help protect children and parents from excess weight gain, yet findings indicate considerable opportunity for continued improvement as well as elucidation of factors affecting concomitant changes in both study groups.

    charges and fees levied from the waste producers. Altogether, financial resources for decommissioning are needed for the following steps: the post-operational phase in which the facility is prepared for dismantling after its final shut-down, dismantling of the radioactive part of the facility, management, storage and disposal of the radioactive waste, restoration of the site, licensing and regulatory supervision of all these steps. Additional means are necessary for the management, storage and disposal of the spent fuel. The way in which the availability of financial resources is secured differs between public owned installations and installations of the private power utilities. In Germany, past practices has resulted in singular contaminated sites of limited extent, mainly during the first half of the 20. century. Those contaminated sites have been or are being cleaned up and redeveloped. In large areas of Saxony and Thuringia, the geological formations permitted the surface and underground mining of Uranium ore. Facilities of the former Soviet-German WISMUT Ltd. where ore was mined and processed from 1946 until the early 1990's can be found at numerous sites. In the course of the re-unification of Germany, the soviet shares of the WISMUT were taken over by the Federal Republic of Germany and the closure of the WISMUT facilities was initiated. In that phase the extent of the damages to the environment and of the necessary remediation work became clear. All mining and milling sites are now closed and are under decommissioning. A comprehensive remediation concept covers all WISMUT sites. Heaps and mill-tailing ponds are transferred into a long-term stable condition. The area of the facilities to be remediated amounts to more than 30 km 2 . Heaps cover a total area of ca. 15,5 km 2 , tailing ponds in which the tailings resulting from the Uranium production are stored as sludges cover 6,3 km 2 ). In total, the remediation issues are very complex and without precedent. The

    Full Text Available Myeloid blast crisis of chronic myeloid leukemia (CML-MBC is rarely seen at presentation and has a poor prognosis. There is no standard therapy for CML-MBC. It is often difficult to distinguish CML-MBC from acute myeloid leukemia expressing the Philadelphia chromosome (Ph+ AML. We present a case in which CML-MBC was seen at the initial presentation in a 75-year-old male. He was treated with conventional AML-directed chemotherapy followed by imatinib mesylate monotherapy, which failed to induce response. However, he achieved long-term complete molecular response after combination therapy involving dasatinib, a second-generation tyrosine kinase inhibitor, and conventional chemotherapy.

    In this paper we describe the services that are offered by CERN for Long Term preservation of High Energy Physics (HEP) data, with the Large Hadron Collider (LHC) as a key use case. Data preservation is a strategic goal for European High Energy Physics (HEP), as well as for the HEP community worldwide and we position our work in this global content. Specifically, we target the preservation of the scientific data, together with the software, documentation and computing environment needed to process, (re-)analyse or otherwise (re-)use the data. The target data volumes range from hundreds of petabytes (PB – 10^15 bytes) to hundreds of exabytes (EB – 10^18 bytes) for a target duration of several decades. The Use Cases driving data preservation are presented together with metrics that allow us to measure how close we are to meeting our goals, including the possibility for formal certification for at least part of this work. Almost all of the services that we describe are fully generic – the exception being A...

    Full Text Available INTRODUCTION: Neuroparacoccidioidomycosis (NPCM is a term used to describe the invasion of the central nervous system by the pathogenic fungus Paracoccidioides brasiliensis. NPCM has been described sporadically in some case reports and small case series, with little or no focus on treatment outcome and long-term follow-up. METHODS: All patients with NPCM from January 1991 to December 2006 were analyzed and were followed until December 2009. RESULTS: Fourteen (3.8% cases of NPCM were identified out of 367 patients with paracoccidioidomycosis (PCM. A combination of oral fluconazole and sulfamethoxazole/trimethoprim (SMZ/TMP was the regimen of choice, with no documented death due to Paracoccidioides brasiliensis infection. Residual neurological deficits were observed in 8 patients. Residual calcification was a common finding in neuroimaging follow-up. CONCLUSIONS: All the patients in this study responded positively to the association of oral fluconazole and sulfamethoxazole/trimethoprim, a regimen that should be considered a treatment option in cases of NPCM. Neurological sequela was a relatively common finding. For proper management of these patients, anticonvulsant treatment and physical therapy support were also needed.

  16. Long-term psychosocial consequences of surgical congenital malformations.

    2017-10-01

    Surgical congenital malformations often represent years of treatment, large number of hospital stays, treatment procedures, and long-term functional sequels affecting patients' psychosocial functioning. Both functional defects and psychosocial difficulties that occur commonly in childhood may pass through adolescence on to adulthood. This overview presents reports published over the past 3 decades to elucidate the long-term psychosocial consequences of surgical congenital malformations. Literature searches conducted on PubMed database revealed that less than 1% of all the records of surgical congenital malformations described long-term psychosocial consequences, but with diverse findings. This inconsistency may be due to methodological differences or deficiencies; especially in study design, patient sampling, and methods. Most of the studies revealed that the functional deficits may have great impact on patients' mental health, psychosocial functioning, and QoL; both short- and long-term negative consequences. Factors other than functional problems, e.g., repeated anesthesia, multiple hospitalization, traumatic treatment procedures, and parental dysfunctioning, may also predict long-term mental health and psychosocial functioning. Through multidisciplinary approach, pediatric surgeons should also be aware of deficits in emotional and psychosocial functioning. To achieve overall optimal psychosocial functioning, the challenge is to find a compromise between physically optimal treatment procedures and procedures that are not psychologically detrimental.

    2002-09-01

    Many of the United States’ hazardous and radioactively contaminated waste sites will not be sufficiently remediated to allow unrestricted land use because funding and technology limitations preclude cleanup to pristine conditions. This means that after cleanup is completed, the Department of Energy will have long-term stewardship responsibilities to monitor and safeguard more than 100 sites that still contain residual contamination. Long-term stewardship encompasses all physical and institutional controls, institutions, information, and other mechanisms required to protect human health and the environment from the hazards remaining. The Department of Energy Long-Term Stewardship National Program is in the early stages of development, so considerable planning is still required to identify all the specific roles and responsibilities, policies, and activities needed over the next few years to support the program’s mission. The Idaho National Engineering and Environmental Laboratory was tasked with leading the development of Science and Technology within the Long-Term Stewardship National Program. As part of that role, a task was undertaken to identify the existing science and technology related requirements, identify gaps and conflicts that exist, and make recommendations to the Department of Energy for future requirements related to science and technology requirements for long-term stewardship. This work is summarized in this document.

    While long-term monitoring and stewardship means many things to many people, DOE has defined it as The physical controls, institutions, information, and other mechanisms needed to ensure protection of people and the environment at sites where DOE has completed or plans to complete cleanup (e.g., landfill closures, remedial actions, and facility stabilization). Across the United States, there are thousands of contaminated sites with multiple contaminants released from multiple sources where contaminants have transported and commingled. The U.S. government and U.S. industry are responsible for most of the contamination and are landowners of many of these contaminated properties. These sites must be surveyed periodically for various criteria including structural deterioration, water intrusion, integrity of storage containers, atmospheric conditions, and hazardous substance release. The surveys, however, are intrusive, time-consuming, and expensive and expose survey personnel to radioactive contamination. In long-term monitoring, there's a need for an automated system that will gather and report data from sensors without costly human labor. In most cases, a SCADA (Supervisory Control and Data Acquisition) unit is used to collect and report data from a remote location. A SCADA unit consists of an embedded computer with data acquisition capabilities. The unit can be configured with various sensors placed in different areas of the site to be monitored. A system of this type is static, i.e., the sensors, once placed, cannot be moved to other locations within the site. For those applications where the number of sampling locations would require too many sensors, or where exact location of future problems is unknown, a mobile sensing platform is an ideal solution. In many facilities that undergo regular inspections, the number of video cameras and air monitors required to eliminate the need for human inspections is very large and far too costly.

    Studies investigating long-term health conditions in patients with craniopharyngioma are limited by short follow-up durations and generally do not compare long-term health effects according to initial craniopharyngioma treatment approach. In addition, studies comparing long-term health conditions between patients with childhood- and adult-onset craniopharyngioma report conflicting results. The objective of this study was to analyse a full spectrum of long-term health effects in patients with craniopharyngioma according to initial treatment approach and age group at craniopharyngioma presentation. Cross-sectional study based on retrospective data. We studied a single-centre cohort of 128 patients with craniopharyngioma treated from 1980 onwards (63 patients with childhood-onset disease). Median follow-up since craniopharyngioma presentation was 13 years (interquartile range: 5-23 years). Initial craniopharyngioma treatment approaches included gross total resection ( n  = 25), subtotal resection without radiotherapy ( n  = 44), subtotal resection with radiotherapy ( n  = 25), cyst aspiration without radiotherapy ( n  = 8), and 90 Yttrium brachytherapy ( n  = 21). Pituitary hormone deficiencies (98%), visual disturbances (75%) and obesity (56%) were the most common long-term health conditions observed. Different initial craniopharyngioma treatment approaches resulted in similar long-term health effects. Patients with childhood-onset craniopharyngioma experienced significantly more growth hormone deficiency, diabetes insipidus, panhypopituitarism, morbid obesity, epilepsy and psychiatric conditions compared with patients with adult-onset disease. Recurrence-/progression-free survival was significantly lower after initial craniopharyngioma treatment with cyst aspiration compared with other therapeutic approaches. Survival was similar between patients with childhood- and adult-onset craniopharyngioma. Long-term health conditions were comparable after

  9. Assessing the market for long-term care services.

    Rice, J A; Taylor, S

    1984-02-01

    Traditionally, long-term care services have been used by a diverse marketplace. The chronically ill, developmentally disabled, mentally ill and aging population has looked to long-term care support services as a means of physical and emotional support. Much of the time these services were housed together for the sake of efficiency. The enormous burden these services are creating on the economy, and the growing aging population, have forced the recognition that long-term care service delivery systems must change. Alternate programming for long-term care services that reach out into the community and into individual homes is becoming an attractive approach to meeting the growing demands of the marketplace. Home health, specialized housing and creative funding mechanisms such as HMOs, are examples of initiatives undertaken by healthcare organizations that view diversification as a vehicle for survival. Market research techniques that have been used in other industries are being adapted to the healthcare industry to ensure the proper mix of services that are demanded by older, more knowledgeable consumers. The programs of the future will be market driven, with the ability of the individual to pay for such services playing a significant role. The healthcare provider of today is in a position to serve the community in new ways. By becoming an integral link in the long-term care system and by developing new programs, the organization can serve as a catalyst for change. It is up to the governing bodies and managers of these facilities to become visionaries and to accept responsibility for assessing the market for long-term care services and to guide their organization into the future.

    Full Text Available Long-term prisoner belongs to a particular category of people who are imprisoned in prisons. On the one hand in this group are often heavily demoralized people who committed the most serious crimes, on the other hand it is a group of prisoners, who should be well thought out and programmed the impact of rehabilitation. The situation of man trapped for years poses in a complicated situation not only the prisoners, but also the entire prison staff. They have to take care of the fact that the prison isolation did not cause the state in which convicts form itself in learned helplessness and lack of skills for self-planning and decision-making. In addition, planning the rehabilitation impact of long-term prisoners should not be forgotten that these prisoners in the short or the long term will return to the libertarian environment therefore, should prevent any negative effects of long-term imprisonment. This article presents the main issues related to the execution of imprisonment against long-term prisoners. It is an attempt to systematize the knowledge of this category of people living in prison isolation.

  12. The long-term nuclear explosives predicament

    International Nuclear Information System (INIS)

    Swahn, J.

    1992-01-01

    A scenario is described, where the production of new military fissile materials is halted and where civil nuclear power is phased out in a 'no-new orders' case. It is found that approximately 1100 tonnes of weapons-grade uranium, 233 tonnes of weapons-grade plutonium and 3795 tonnes of reactor-grade plutonium have to be finally disposed of as nuclear waste. This material could be used for the construction of over 1 million nuclear explosives. Reactor-grade plutonium is found to be easier to extract from spent nuclear fuel with time and some physical characteristics important for the construction of nuclear explosives are improved. Alternative methods for disposal of the fissile material that will avoid the long-term nuclear explosives predicament are examined. Among these methods are dilution, denaturing or transmutation of the fissile material and options for practicably irrecoverable disposal in deep boreholes, on the sea-bed, and in space. It is found that the deep boreholes method for disposal should be the primary alternative to be examined further. This method can be combined with an effort to 'forget' where the material was put. Included in the thesis is also an evaluation of the possibilities of controlling the limited civil nuclear activities in a post-nuclear world. Some surveillance technologies for a post-nuclear world are described, including satellite surveillance. In a review part of the thesis, methods for the production of fissile material for nuclear explosives are described, the technological basis for the construction of nuclear weapons is examined, including use of reactor-grade plutonium for such purposes; also plans for the disposal of spent fuel from civil nuclear power reactors and for the handling of the fissile material from dismantled warheads is described. The Swedish plan for the handling and disposal of spent nuclear fuel is described in detail. (490 refs., 66 figs., 27 tabs.)

    Full Text Available The number of long-term survivors is increasing in the western countries due to remarkable improvements in the treatment of childhood cancer. The long-term complications of childhood cancer survivors in these countries were brought to light by the childhood cancer survivor studies. In Korea, the 5-year survival rate of childhood cancer patients is approaching 70%; therefore, it is extremely important to undertake similar long-term follow-up studies and comprehensive long-term care for our population. On the basis of the experiences of childhood cancer survivorship care of the western countries and the current Korean status of childhood cancer survivors, long-term follow-up study and long-term care systems need to be established in Korea in the near future. This system might contribute to the improvement of the quality of life of childhood cancer survivors through effective intervention strategies.

  14. Does management intensity in inter rows effect soil physical properties in Austrian and Romanian vineyards?

    Successful viticulture is mainly influenced by soil and climate. The availability of water during the growing season highly influences wine quality and quantity. To protect soil from being eroded most of the winegrowers keep the inter row zones of the vineyards green. Greening also helps to provide water-stress to the grapes for harvesting high quality wines. However, these greening strategies concerning the intensity of inter row management differ from farm to farm and are mainly based on personal experience of the winegrowers. However to what extent different inter row management practices affect soil physical properties are not clearly understood yet. To measure possible effects of inter row management in vineyards on soil physical parameters we selected paired vineyards with different inter row management in Austria and Romania. In total more than 7000 soil analysis were conducted for saturated and unsaturated hydraulic conductivity, soil water retention, water stable aggregates, total organic carbon, cation exchange capacity, potassium, phosphorous, soil texture, bulk density and water infiltration. The comparison between high intensity management with at least one soil disturbance per year, medium intensity with one soil disturbance every second inter row per year and low intensity management with no soil disturbance since at least 5 years indicates that investigated soil physical properties did not improve for the upper soil layer (3-8cm). This is in contrast to general perceptions of improved soil physical properties due to low intensity of inter row management, i.e. permanent vegetated inter rows. This may be attributed to long term and high frequency mechanical stress by agricultural machinery in inter rows.

    Full Text Available The extent to which exchange rates of four major currencies against the Greek Drachma exhibit long-term dependence is investigated using a R/S analysis testing framework. We show that both classic R/S analysis and the modified R/S statistic if enhanced by bootstrapping techniques can be proven very reliable tools to this end. Our findings support persistence and long-term dependence with non-periodic cycles for the Deutsche Mark and the French Franc series. In addition a noisy chaos explanation is favored over fractional Brownian motion. On the contrary, the US Dollar and British Pound were found to exhibit a much more random behavior and lack of any long-term structure.

    1995-01-01

    In a planning system intended to be governed primarily by policies in statutory plans a reasonable horizon for long term planning is 10 years or longer. Because of statutory requirements, developers have no option but to pay due regard to, and take a full part in, long term planning. The paper examines the type of policies which have emerged in the last few years to cater for wind energy development. It canvasses the merits of different types of policies. Finally, it discusses the policy framework which may emerge to cater for development outside NFFO. (Author)

    Long-term characteristics of the nuclear emulsion so called 'OPERA film' used in the neutrino oscillation experiment, OPERA, has been studied for 8 years since its production or refreshing after it. In the results, it turned out to be excellent in sensitivity, amount of random noise, and refreshing characteristics. The retention capacity of latent image of tracks was also studied. The result will open the way to the recycling of 7,000,000 emulsion films which will remain not developed after 5 years of OPERA's run, and other long-term experiments with emulsion.

    As new nuclear fuel reprocessing plants go on stream, the collection of fission product 85 Kr will be required to avoid potential local release problems and long-term atmospheric buildup. Storage of the collected 85 Kr for a period of at least 100 years will be necessary to allow approximately 99.9 percent decay before it is released. A program designed to develop and evaluate proposed methods for long-term storage of 85 Kr is discussed, and the results of a preliminary evaluation of three methods, high pressure steel cylinders, zeolite encapsulation, and clathrate inclusion are presented.

    Herrera-Gomez, A.; Spicer, W.E.

    1993-08-01

    A new high-intensity, short-time electron source is now being used at the Stanford Linear Accelerator Center (SLAC). Using a GaAs negative affinity semiconductor in the construction of the cathode, it is possible to fulfill operation requirements such as peak currents of tens of amperes, peak widths of the order of nanoseconds, hundreds of hours of operation stability, and electron spin polarization. The cathode is illuminated with high intensity laser pulses, and photoemitted electrons constitute the yield. Because of the high currents, some nonlinear effects are present. Very noticeable is the so-called Charge Limit (CL) effect, which consists of a limit on the total charge in each pulse-that is, the total bunch charge stops increasing as the light pulse total energy increases. In this paper, we explain the mechanism of the CL and how it is caused by the photovoltaic effect. Our treatment is based on the Three-Step model of photoemission. We relate the CL to the characteristics of the surface and bulk of the semiconductor, such as doping, band bending, surface vacuum level, and density of surface states. We also discuss possible ways to prevent the Char's Level effect

    Directory of Open Access Journals (Sweden)

    Christian Schultheis

    Full Text Available Channelrhodopsin-2 (ChR2 is widely used for rapid photodepolarization of neurons, yet, as it requires high-intensity blue light for activation, it is not suited for long-term in vivo applications, e.g. for manipulations of behavior, or photoactivation of neurons during development. We used "slow" ChR2 variants with mutations in the C128 residue, that exhibit delayed off-kinetics and increased light sensitivity in Caenorhabditis elegans. Following a 1 s light pulse, we could photodepolarize neurons and muscles for minutes (and with repeated brief stimulation, up to days with low-intensity light. Photoactivation of ChR2(C128S in command interneurons elicited long-lasting alterations in locomotion. Finally, we could optically induce profound changes in animal development: Long-term photoactivation of ASJ neurons, which regulate larval growth, bypassed the constitutive entry into the "dauer" larval state in daf-11 mutants. These lack a guanylyl cyclase, which possibly renders ASJ neurons hyperpolarized. Furthermore, photostimulated ASJ neurons could acutely trigger dauer-exit. Thus, slow ChR2s can be employed to long-term photoactivate behavior and to trigger alternative animal development.

    2012-07-01

    The objective of this article is to examine the association of teen motherhood and long-term physical and mental health outcomes. The physical and mental health components (PCS and MCS) of the SF-12 Healthy Survey in the NLSY79 health module were used to assess long-term health outcomes of women who experienced teenage motherhood. Various familial, demographic, and environmental characteristics were indentified and controlled for that may have predicted teen motherhood and long-term health outcomes. The two comparison groups for teen mothers were women who experienced teen-pregnancy only and women who were engaged in unprotected sexual activity as a teenage but did not experience pregnancy. Multivariate ordinary least squares regression was used for analysis. The average PCS and MCS for teen mothers was 49.91 and 50.89, respectively. Teen mothers exhibited poorer physical health later in life compared to all women as well as the comparison groups. When controlling for age, teen mothers had significantly lower PCS and MCS scores compared to all other women. Furthermore, when controlling for familial, demographic, and environmental characteristics, teen mothers exhibited significantly lower PCS and MCS scores. When comparing teen mothers to the two comparison groups, PCS was not statistically different although MCS was significantly lower in the teen-pregnancy group. Teen motherhood does lead to poorer physical health outcomes later in life. On the other hand, poorer mental health outcomes in later life may be attributed to the unmeasured factors leading to a teen pregnancy and not teen motherhood itself. Additional research needs to be conducted on the long-term consequences of teen motherhood.

However, many people report that they have successfully managed weight loss maintenance in the long term. Several factors have been associated with better weight loss maintenance in long-term observational and randomized studies. A few pertain to the behavioral area (eg, high levels of physical activity, eating a low-calorie, low-fat diet; frequent self-monitoring of weight, a few to the cognitive component (eg, reduced disinhibition, satisfaction with results achieved, confidence in being able to lose weight without professional help, and a few to personality traits (eg, low novelty seeking and patient–therapist interaction. Trials based on the most recent protocols of lifestyle modification, with a prolonged extended treatment after the weight loss phase, have also shown promising long-term weight loss results. These data should stimulate the adoption of a lifestyle modification-based approach for the management of obesity, featuring a nonphysician lifestyle counselor (also called “lifestyle trainer” or “healthy lifestyle practitioner” as a pivotal component of the multidisciplinary team. The obesity physicians maintain a primary role in engaging patients, in team coordination and supervision, in managing the complications associated with obesity and, in selected cases, in the decision for drug treatment or bariatric surgery, as possible more intensive, add-on interventions to lifestyle treatment.

    Paul, Fiona; Rattray, Janice

    2008-05-01

    This paper is a report of a literature review undertaken to identify the short- and long-term impact of critical illness on relatives. Patients in intensive care can experience physical and psychological consequences, and their relatives may also experience such effects. Although it is recognized that relatives have specific needs, it is not clear whether these needs are always met and whether further support is required, particularly after intensive care. The following databases were searched for the period 1950-2007: Medline, British Nursing Index and Archive, EMBASE, CINAHL, PsycINFO and EMB Reviews--Cochrane Central Register of Clinical Trials. Search terms focused on adult relatives of critically ill adult patients during and after intensive care. Recurrent topics were categorized to structure the review, i.e. 'relatives needs', 'meeting relatives' needs', 'interventions', 'satisfaction', 'psychological outcomes' and 'coping'. Studies have mainly identified relatives' immediate needs using the Critical Care Family Needs Inventory. There are few studies of interventions to meet relatives' needs and the short- and long-term effects of critical illness on relatives. Despite widespread use of the Critical Care Family Needs Inventory, factors such as local or cultural differences may influence relatives' needs. Relatives may also have unidentified needs, and these needs should be explored. Limited research has been carried out into interventions to meet relatives' needs and the effects of critical illness on their well-being, yet some relatives may experience negative psychological consequences far beyond the acute phase of the illness.

    The purpose of this report is to establish the content and structural validity of the Long-term Industrial Energy Forecasting (LIEF) model, and to provide estimates for the model`s parameters. The model is intended to provide decision makers with a relatively simple, yet credible tool to forecast the impacts of policies which affect long-term energy demand in the manufacturing sector. Particular strengths of this model are its relative simplicity which facilitates both ease of use and understanding of results, and the inclusion of relevant causal relationships which provide useful policy handles. The modeling approach of LIEF is intermediate between top-down econometric modeling and bottom-up technology models. It relies on the following simple concept, that trends in aggregate energy demand are dependent upon the factors: (1) trends in total production; (2) sectoral or structural shift, that is, changes in the mix of industrial output from energy-intensive to energy non-intensive sectors; and (3) changes in real energy intensity due to technical change and energy-price effects as measured by the amount of energy used per unit of manufacturing output (KBtu per constant $ of output). The manufacturing sector is first disaggregated according to their historic output growth rates, energy intensities and recycling opportunities. Exogenous, macroeconomic forecasts of individual subsector growth rates and energy prices can then be combined with endogenous forecasts of real energy intensity trends to yield forecasts of overall energy demand. 75 refs.

    Radioactive wastes can be disposed of in deep salt formations. Rock salt is a suitable geologic medium because of its unique characteristics. Open boreholes, shafts and drifts are created to provide physical access to the repository. Long-term seals must be emplaced in those potential pathways to prevent radioactive release to the biosphere. The sealing materials must be mechanically and, most important, geochemically stable within the host rock. Salt bricks made of compressed salt-powder are understood to be the first choice long-term sealing material. Seals built from salt bricks will be ductile. The permeability of the salt bricks is assumed to be in the order of 2*10 -15 m 2 . Large sealing systems are built by combining the individual bricks with mortar. Raw materials for mortar are fine-grained halite powder and ground saliferous clay. The permeability of the mortar decreases with its salt content to approx. 2*10 -14 m 2 . Moistened saliferous clay may show temporary swelling. Sealing experiments will be carried out in the Asse salt mine. Long-term seals will be built into holes of 1 m diameter. The contact and merging of the brick-wall with the surrounding rock salt will be investigated in long-term tests. Within the in situ sealing program a number of geophysical methods are applied. Acoustic emission measurements are used to study the effects of high pressure gas injection and a geoelectrical observation program is aiming to estimate the permeability in and around the long-term seal. High frequency electromagnetic methods contribute to the knowledge of the petrophysical rock properties. 11 refs., 12 figs

    This study tested the effectiveness of a multifaceted, cognitive-behavioral therapy (CBT) program for antisocial children--the SNAP Under 12 Outreach Project (ORP)--in relation to age, sex and indices of treatment intensity. Study participants were 80 clinic-referred children (59 boys and 21 girls) aged 6-11 years assigned to one of the following groups: control (CG; n = 14) who did not receive the ORP, matched (MG; n = 50) who received the ORP, and experimental (EG; n = 16) who received an enhanced version of the ORP. Results indicated significant pre-post changes for the EG and MG for Child Behavior Checklist (CBCL)-measured delinquency and aggression, but no improvement for the CG. Positive relationships between the number of individual ORP components (e.g. number of children's CBT sessions) received and CBCL change scores were also found. Statistical associations tended to be larger for girls and older children (i.e. 10-11 years old) who may have been more cognitively advanced. Also, the number of children's CBT sessions predicted later convictions, even after controlling for prior CBCL delinquency scores. Findings from this study support the effectiveness of the ORP, but also highlight the need to take into account client characteristics when offering clinical treatment.

    The relative merits of reduced intensity hematopoietic stem cell transplantation (RIST) for chronic myeloid leukemia (CML) in the first chronic phase (CP) in imatinib era have not been evaluated. The study was designed to compare the outcomes of combination therapy of RIST plus imatinib (RIST + IM) vs. imatinib (IM) alone for young patients with early CP (ECP) and late CP (LCP). Of the patients, 130 were non-randomly assigned to treatment with IM alone (n = 88) or RIST + IM (n = 42). The 10-year overall survival (OS) and event-free survival (EFS) were comparable between RIST + IM and IM groups. LCP, high Sokal score, and no complete cytogenetic response at 3 months were adverse prognostic factors for survival, but only the time from diagnosis to IM was an independent predictor after multivariate analysis. For ECP, IM was similar to RIST + IM, with 10-year EFS rates of 77.2 vs. 81.6% (p = 0.876) and OS rates of 93.8 vs. 87.9% (p = 0.102), respectively. For LCP, both treatments resulted in similar survival, but more patients in the imatinib group experienced events (10-year EFS 40.8 vs. 66.7%, p = 0.047). The patients with higher EBMT risk scores had an inferior survival than those with lower scores (69.2 vs. 92.9%, p = 0.04). We concluded that RIST + IM was comparable to IM in terms of OS and EFS. However, RIST + IM was more affordable than IM alone in a 10-year scale. Thus, RIST + IM could be considered as an alternative treatment option, especially when the patients have low EBMT risk scores and demand a definite cure for CML.

  6. Applied Physics Education: PER focused on Physics-Intensive Careers

    Physics education research is moving beyond classroom learning to study the application of physics education within STEM jobs and PhD-level research. Workforce-related PER is vital to supporting physics departments as they educate students for a diverse range of careers. Results from an on-going study involving interviews with entry-level employees, academic researchers, and supervisors in STEM jobs describe the ways that mathematics, physics, and communication are needed for workplace success. Math and physics are often used for solving ill-structured problems that involve data analysis, computational modeling, or hands-on work. Communication and collaboration are utilized in leadership, sales, and as way to transfer information capital throughout the organization through documentation, emails, memos, and face-to-face discussions. While managers and advisors think a physics degree typically establishes technical competency, communication skills are vetted through interviews and developed on the job. Significant learning continues after graduation, showing the importance of cultivating self-directed learning habits and the critical role of employers as educators of specialized technical abilities through on-the-job training.

    The author firstly gives a summary overview of the knowledge base acquired since the first breeder reactors became operational in the 1950s. "Neutronics", thermal phenomena, reactor core cooling, various coolants used and envisioned for this function, fuel fabrication from separated materials, main equipment (pumps, valves, taps, waste cock, safety circuits, heat exchange units, etc.) have now attained maturity, sufficient to implement sodium cooling circuits. Notwithstanding, the use of metallic sodium still raises certain severe questions in terms of safe handling (i.e. inflammability) and other important security considerations. The structural components, both inside the reactor core and outside (i.e. heat exchange devices) are undergoing in-depth research so as to last longer. The fuel cycle, notably the refabrication of fuel elements and fertile elements, the case of transuranic elements, etc., call for studies into radiation induced phenomena, chemistry separation, separate or otherwise treatments for materials that have different radioactive, physical, thermodynamical, chemical and biological properties. The concerns that surround the definitive disposal of certain radioactive wastes could be qualitatively improved with respect to the pressurized water reactors (PWRs) in service today. Lastly, the author notes that breeder reactors eliminate the need for an isotope separation facility, and this constitutes a significant contribution to contain nuclear proliferation. Among the priorities for a fully operational system (power station - the fuel cycle - operation-maintenance - the spent fuel pool and its cooling system-emergency cooling system-emergency electric power-transportation movements-equipment handling - final disposal of radioactive matter, independent safety barriers), the author includes materials (fabrication of targets, an irradiation and inspection instrument), the chemistry of all sorting processes, equipment "refabrication" or rehabilitation

    The association of sub-optimal selenium status with increased risk factors for some cancers has been reported in two recent epidemiological studies. In both studies the same threshold in selenium status was observed, below which, cancer incidence increased. To assess the use of nails as a biologic monitor to measure the long-term selenium status, an eight-year longitudinal study was undertaken with a group of 11 adult subjects, 5 women and 6 men. Selenium has been measured by instrumental neutron activation analysis. Differences between fingernails and toenails with be discussed. In addition, the results will be discussed in the context of the long-term stability of the nail monitor to measure selenium status during those periods when selenium determinants are static; and the changes that occur as a result of selenium supplementation.

    Long-term care facility environments and the vulnerability of their residents provide a setting conducive to the rapid spread of influenza virus and other respiratory pathogens. Infections may be introduced by staff, visitors or new or transferred residents, and outbreaks of influenza in such settings can have devastating consequences for individuals, as well as placing extra strain on health services. As the population ages over the coming decades, increased provision of such facilities seems likely. The need for robust infection prevention and control practices will therefore remain of paramount importance if the impact of outbreaks is to be minimised. In this review, we discuss the nature of the problem of influenza in long-term care facilities, and approaches to preventive and control measures, including vaccination of residents and staff, and the use of antiviral drugs for treatment and prophylaxis, based on currently available evidence. © 2017 The Authors.

    in Denmark. Industrial foundations are independent legal entities without owners or members typically with the dual objective of preserving the company and using excess profits for charity. We use a unique Danish data set to examine the governance of foundation-owned companies. We show that they are long......-term in several respects. Foundations hold on to their shares for longer. Foundation-owned companies replace managers less frequently. They have more conservative capital structures with less leverage. Their companies survive longer. Their business decisions appear to be more long term. This paper supports...... the hypothesis that time horizons are influenced by ownership structures and particularly that industrial foundations promote longtermism. Policymakers which are interested in promoting longtermism should allow and perhaps even encourage the creation of industrial foundations. More generally they should consider...

    When addressing the role of fusion energy in the 21. century, the evaluation of possible future structures in the electricity market and the energy sector as a whole, can be a useful tool. Because fusion energy still needs demonstration, commercialized fusion energy is not likely to be a reality within the next few decades. Therefore long-term scenarios are needed describing the energy markets, which fusion energy eventually will be part of. This report performs an analysis of two of the most detailed existing long-term scenarios describing possible futures of the energy system. The aim is to clarify the frames in which the future development of the global energy demand, as well as the structure of the energy system can be expected to develop towards the year 2100.

    1981-01-01

    It is pointed out that sources of long-term damage from radiation are two-fold. People who have been exposed to doses of radiation from initial early fallout but have recovered from the acute effects may still suffer long-term damage from their exposure. Those who have not been exposed to early fallout may be exposed to delayed fallout, the hazards from which are almost exclusively from ingesting strontium, caesium and carbon isotopes present in food; the damage caused is relatively unimportant compared with that caused by the brief doses from initial radiation and early fallout. A brief discussion is presented of the distribution of delayed long-lived isotope fallout, and an outline is sketched of late biological effects, such as malignant disease, cataracts, retarded development, infertility and genetic effects.

    We employ the Bayesian framework to define a cointegration measure aimed to represent long term relationships between time series. For visualization of these relationships we introduce a dissimilarity matrix and a map based on the sorting points into neighborhoods (SPIN) technique, which has been previously used to analyze large data sets from DNA arrays. We exemplify the technique in three data sets: US interest rates (USIR), monthly inflation rates and gross domestic product (GDP) growth rates.

    Background With the recent emergence of conjugated bile acids as signaling molecules in cancer, a murine model of obstructive jaundice by cholestasis with long-term survival is in need. Here, we investigated the characteristics of 3 murine models of obstructive jaundice. Methods C57BL/6J mice were used for total ligation of the common bile duct (tCL), partial common bile duct ligation (pCL), and ligation of left and median hepatic bile duct with gallbladder removal (LMHL) models. Survival was assessed by Kaplan-Meier method. Fibrotic change was determined by Masson-Trichrome staining and Collagen expression. Results 70% (7/10) of tCL mice died by Day 7, whereas majority 67% (10/15) of pCL mice survived with loss of jaundice. 19% (3/16) of LMHL mice died; however, jaundice continued beyond Day 14, with survival of more than a month. Compensatory enlargement of the right lobe was observed in both pCL and LMHL models. The pCL model demonstrated acute inflammation due to obstructive jaundice 3 days after ligation but jaundice rapidly decreased by Day 7. The LHML group developed portal hypertension as well as severe fibrosis by Day 14 in addition to prolonged jaundice. Conclusion The standard tCL model is too unstable with high mortality for long-term studies. pCL may be an appropriate model for acute inflammation with obstructive jaundice but long term survivors are no longer jaundiced. The LHML model was identified to be the most feasible model to study the effect of long-term obstructive jaundice. PMID:27916350

    IRSN presents its statement regarding long-term storage facilities; in France, the regulatory documents do not define the long term duration. The storage facility lifetime can only be appreciated according to the needs and materials stored therein. However, the magnitude of the long-term can be estimated at a few hundred years compared to a few decades for current storage. Usually, in France, construction of storage facilities is driven from the necessity various necessities, linked to the management of radioactive material (eg spent fuel) and to the management of radioactive waste. Because of the variety of 'stored materials and objects' (fission product solutions, plutonium oxide powders, activated solids, drums containing technological waste, spent fuel...), a great number of storage facility design solutions have been developed (surface, subsurface areas, dry or wet conditions...) in the World. After describing the main functions of a storage facility, IRSN displays the safety principles and the associated design principles. The specific design principles applied to particular storage (dry or wet spent fuel storage, depleted uranium or reprocessed uranium storage, plutonium storage, waste containing tritium storage, HLW and ILLW storage...) are also presented. Finally, the concerns due to the long-term duration storage and related safety assessment are developed. After discussing these issues, IRSN displays its statement. The authorization procedures governing the facility lifetime are similar to those of any basic nuclear installation, the continuation of the facility operation remaining subject to periodic safety reviews (in France, every 10 years). The applicant safety cases have to show, that the safety requirements are always met; this requires, at minimum, to take into account at the design stage, comfortable design margins. (author)

In a dynamic relationship, the agent's shirking not only reduces current performance but also increases the agent's information rent due to the persistent belief manipulation effect. We characterize the optimal contract using the dynamic programming technique in which information rent is the unique state variable. In the optimal contract, the optimal effort is front-loaded and decr...

    Long-term investors face a common problem-how to maintain the purchasing power of their assets over time and achieve a level of real returns consistent with their investment objectives. While inflation-linked bonds and derivatives have been developed to hedge the effects of inflation, their limited supply and liquidity lead many investors to continue to rely on the indirect hedging properties of traditional asset classes. In this paper, we assess these properties over different time horizons,...

    2004-12-01

    A comprehensive program of lifestyle modification induces loss of approximately 10% of initial weight in 16 to 26 weeks, as revealed by a review of recent randomized controlled trials, including the Diabetes Prevention Program. Long-term weight control is facilitated by continued patient-therapist contact, whether provided in person or by telephone, mail, or e-mail. High levels of physical activity and the consumption of low-calorie, portion-controlled meals, including liquid meal replacements, can also help maintain weight loss. Additional studies are needed of the effects of macronutrient content (e.g., low-fat vs. low-carbohydrate diets) on long-term changes in weight and health. Research also is needed on effective methods of providing comprehensive weight loss control to the millions of Americans who need it.

    We assessed the intrapersonal, interpersonal, and organizational factors that predicted job satisfaction among long-term care employees. Baseline data were used to describe characteristics that influence job satisfaction. Using a forced linear regression model, while controlling for age and job title, we assessed if higher physical activity levels, fewer symptoms of depression, stress, and/or anxiety (ie, decreased mood), less back pain, stronger social support, and reports of low work demands were associated with higher job satisfaction. Mood (β = -0.412, P = 0.003) explained 17% of the variance in job satisfaction. This information can be used to guide facility wide programs and interventions aimed at increasing job satisfaction among all long-term care staff.

    Full Text Available The long-term observation of active geological processes is a major research goal in an increasing number of scientific drilling projects. An extended monitoring phase within a potentially hostile environment (e.g., temperature, pressure, salinity requires new long-lasting and robust instrumentation currently unavailable from either industry or academia. Extended exposure of instrument packages to extreme conditions will typically cause seals to weaken and fail,electronic parts to break under permanent load, and sensors to degrade or develop strong drift. In the framework of scientific exploration, there are currently several major research projects targeting fault zone drilling and in situ measurements to monitor physical and chemical conditions before, during, and after seismic events. Planning has now begun for tool development, testing, and continuous long-term monitoring for the San Andreas Fault Zone Observatory at Depth, SAFOD (Parkfi eld, Calif., U.S.A.; See article on page 32..

    Hybrid systems (source-driven subcritical reactors), are investigated at CEA, mainly from a conceptual point of view, in order to assess their potential to transmute radioactive wastes (mainly long-lived fission products, LLFP) and their potential to insure a minimal long-term radiological risk related both to the fuel inventory inside the system and to the full fuel cycle (mass flows, reprocessing transport, waste disposal). The physics of these systems has been explored and work is in progress both in the field of basic data and INC code validation, in the frame of international collaborations and in the field of conceptual design studies. The most interesting feature of subcritical source-driven system is related to the possibility to obtain an {open_quotes}excess{close_quotes} of neutrons per fission, which can be used to reduce the long-term radiological risk. A specific example will be discussed here.

    2008-12-01

    Long-term forestry, watershed, and ecological research sites have become critical, productive nodes for environmental science research and in some cases for work in the social sciences and humanities. The Forest Service's century-old Experimental Forests and Ranges and the National Science Foundation's 28- year-old Long-Term Ecological Research program have been remarkably productive in both basic and applied sciences, including characterization of acid rain and old-growth ecosystems and development of forest, watershed, and range management systems for commercial and other land use objectives. A review of recent developments suggests steps to enhance the function of collections of long-term research sites as interactive science networks. The programs at these sites have evolved greatly, especially over the past few decades, as the questions addressed, disciplines engaged, and degree of science integration have grown. This is well displayed by small, experimental watershed studies, which first were used for applied hydrology studies then more fundamental biogeochemical studies and now examination of complex ecosystem processes; all capitalizing on the legacy of intensive studies and environmental monitoring spanning decades. In very modest ways these collections of initially independent sites have functioned increasingly as integrated research networks addressing inter-site questions by using common experimental designs, being part of a single experiment, and examining long-term data in a common analytical framework. The network aspects include data sharing via publicly-accessible data-harvester systems for climate and streamflow data. The layering of one research or environmental monitoring network upon another facilitates synergies. Changing climate and atmospheric chemistry highlight a need to use these networks as continental-scale observatory systems for assessing the impacts of environmental change on ecological services.

    Anthropogenic disturbance of natural vegetation profoundly alters the lateral and vertical fluxes of soil nutrients and particles at the land surface. Human-induced acceleration of soil erosion can thereby result in an imbalance between physical erosion, soil production and chemical weathering. The (de-)coupling between physical erosion and chemical weathering in ecosystems with strong anthropogenic disturbances is not yet fully understood, as earlier studies mostly focused on natural ecosystems. In this study, we explore the chemical weathering intensity for four study sites located in the Internal Zone of the Spanish Betic Cordillera. Most of the sites belong to the Nevado-Filabres complex, but are characterized by different rates of long-term exhumation, 10Be catchment-wide denudation and hill slope morphology. Denudation rates are generally low, but show large variation between the three sites (from 23 to 246 mm kyr-1). The magnitude of denudation rates is consistent with longer-term uplift rates derived from marine deposits, fission-track measurements and vertical fault slip rates. Two to three soil profiles were sampled per study site at exposed ridge tops. All soils overly fractured mica schist, and are very thin (< 60cm). In each soil profile, we sampled 5 depth slices, rock fragments and the (weathered) bedrock. In total, 38 soil and 20 rock samples were analyzed for their chemical composition. The chemical weathering intensity is constrained by the Chemical Depletion Fraction that is based on a chemical mass balance approach using Zr as an immobile element. Chemical weathering accounts for 5 to 35% of the total mass lost due to denudation. We observe systematically higher chemical weathering intensities (CDFs) in sites with lower denudation rates (and vice versa), suggesting that weathering is supply-limited. Our measurements of soil elemental losses from 10 soil profiles suggest that the observed variation in chemical weathering is strongly associated

    Intense antimicrobial use in long term care facilities promotes the emergence and persistence of antimicrobial resistant organisms and leads to adverse effects such as C. difficile colitis. Guidelines recommend development of antimicrobial stewardship programs for these facilities to promote optimal antimicrobial use. However, the effectiveness of these programs or the contribution of any specific program component is not known. For this review, publications describing evaluation of antimicrobial stewardship programs for long term care facilities were identified through a systematic literature search. Interventions included education, guidelines development, feedback to practitioners, and infectious disease consultation. The studies reviewed varied in types of facilities, interventions used, implementation, and evaluation. Comprehensive programs addressing all infections were reported to have improved antimicrobial use for at least some outcomes. Targeted programs for treatment of pneumonia were minimally effective, and only for indicators of uncertain relevance for stewardship. Programs focusing on specific aspects of treatment of urinary infection - limiting treatment of asymptomatic bacteriuria or prophylaxis of urinary infection - were reported to be effective. There were no reports of cost-effectiveness, and the sustainability of most of the programs is unclear. There is a need for further evaluation to characterize effective antimicrobial stewardship for long term care facilities.

    Low back pain remains a costly quality-of-life-related health problem. Microdiscectomy is often the surgical procedure of choice for a symptomatic, single-level, lumbar disc herniation in younger and middle-aged adults. The question of whether a post-microdiscectomy exercise program enhances function, quality of life, and disability status has not been systematically explored. Thus, the overall purpose of this study is to assess immediate and long-term outcomes of an exercise program, developed at University of Southern California (USC), targeting the trunk and lower extremities (USC Spine Exercise Program) for persons who have undergone a single-level microdiscectomy for the first time. One hundred individuals between the ages of 18 and 60 who consent to undergo lumbar microdiscectomy will be recruited to participate in this study. Subjects will be randomly assigned to one of two groups: 1) one session of back care education, or 2) a back care education session followed by the 12-week USC Spine Exercise Program. The outcome examiners (evaluators), as well as the data managers, will be blinded to group allocation. Education will consist of a one-hour "one-on-one" session with the intervention therapist, guided by an educational booklet specifically designed for post-microdiscectomy care. This session will occur four to six weeks after surgery. The USC Spine Exercise Program consists of two parts: back extensor strength and endurance, and mat and upright therapeutic exercises. This exercise program is goal-oriented, performance-based, and periodized. It will begin two to three days after the education session, and will occur three times a week for 12 weeks. Primary outcome measures include the Oswestry Disability Questionnaire, Roland-Morris Disability Questionnaire, SF-36 quality of life assessment, Subjective Quality of Life Scale, 50-foot Walk, Repeated Sit-to-Stand, and a modified Sorensen test. The outcome measures in the study will be assessed before and after

    To identify the main issues of importance when living with long-term conditions to refine a conceptual framework for informing the item development of a patient-reported outcome measure for long-term conditions. Semi-structured qualitative interviews (n=48) were conducted with people living with at least one long-term condition. Participants were recruited through primary care. The interviews were transcribed verbatim and analyzed by thematic analysis. The analysis served to refine the conceptual framework, based on reviews of the literature and stakeholder consultations, for developing candidate items for a new measure for long-term conditions. Three main organizing concepts were identified: impact of long-term conditions, experience of services and support, and self-care. The findings helped to refine a conceptual framework, leading to the development of 23 items that represent issues of importance in long-term conditions. The 23 candidate items formed the first draft of the measure, currently named the Long-Term Conditions Questionnaire. The aim of this study was to refine the conceptual framework and develop items for a patient-reported outcome measure for
