The palatable, energy-dense foods that characterize modern environments can promote unhealthy eating habits, along with humans' predispositions to accept sweet tastes and reject those that are sour or bitter. Yet food preferences are malleable, and examining food preference learning during early life can highlight ways to promote acceptance of healthier foods. This narrative review describes research from the past 10 years focused on food preference learning from the prenatal period through early childhood (ages 2-5 years). Exposure to a variety of healthy foods from the start, including during the prenatal period, early milk-feeding and the introduction to complementary foods and beverages, can support subsequent acceptance of those foods. Yet development is plastic, and healthier food preferences can still be promoted after infancy. In early childhood, research supports starting with the simplest strategies, such as repeated exposure and modelling, reserving other strategies for use when needed to motivate the initial tasting necessary for repeated exposure effects to begin. This review can help caregivers and practitioners to promote the development of healthy food preferences early in life. Specific implementation recommendations, the role of individual differences and next steps for research in this area are also discussed. © 2017 World Obesity Federation.

Electro-thermal modelling of polymer lithium batteries for starting period and pulse power

NASA Astrophysics Data System (ADS)

Baudry, P.; Neri, M.; Gueguen, M.; Lonchampt, G.

Since power capabilities of solid polymer lithium batteries can only be delivered above 60 °C, the thermal management in electric-vehicle applications has to be carefully considered. Electro-thermal modelling of a thermally insulated 200 kg battery was performed, and electrochemical data were obtained from laboratory cell impedance measurements at 20 and 80 °C. Starting at 20 °C as initial working temperature, the battery reaches 40 °C after 150 s of discharge in a 0.5 Ω resistance. At 40 °C, the useful peak power is 20 kW. The energy expense for heating the battery from 20 to 40 °C is 1.4 kWh, corresponding to 6% of the energy available in the battery. After a stand-by period of 24 h, the temperature decreases from 80 to 50 °C, allowing efficient starting conditions.

It is well established that warming leads to longer growing seasons in seasonally cold ecosystems. Whether this goes along with an increase in the net ecosystem carbon dioxide (CO 2 ) uptake is much more controversial. We studied the effects of warming on the start of the carbon uptake period (CUP) of three mountain grasslands situated along an elevational gradient in the Alps. To this end we used a simple empirical model of the net ecosystem CO 2 exchange, calibrated and forced with multi-year empirical data from each site. We show that reductions in the quantity and duration of daylight associated with earlier snowmelts were responsible for diminishing returns, in terms of carbon gain, from longer growing seasons caused by reductions in daytime photosynthetic uptake and increases in nighttime losses of CO 2 . This effect was less pronounced at high, compared to low, elevations, where the start of the CUP occurred closer to the summer solstice when changes in day length and incident radiation are minimal.

Objectives To estimate mortality rates and prognostic factors in HIV-positive patients who started combination antiretroviral therapy between 1996–1999 and survived for more than ten years. Methods We used data from 18 European and North American HIV cohort studies contributing to the Antiretroviral Therapy Cohort Collaboration. We followed up patients from ten years after start of combination antiretroviral therapy. We estimated overall and cause-specific mortality rate ratios for age, sex, transmission through injection drug use, AIDS, CD4 count and HIV-1 RNA. Results During 50,593 person years 656/13,011 (5%) patients died. Older age, male sex, injecting drug use transmission, AIDS, and low CD4 count and detectable viral replication ten years after starting combination antiretroviral therapy were associated with higher subsequent mortality. CD4 count at ART start did not predict mortality in models adjusted for patient characteristics ten years after start of antiretroviral therapy. The most frequent causes of death (among 340 classified) were non-AIDS cancer, AIDS, cardiovascular, and liver-related disease. Older age was strongly associated with cardiovascular mortality, injecting drug use transmission with non-AIDS infection and liver-related mortality, and low CD4 and detectable viral replication ten years after starting antiretroviral therapy with AIDS mortality. Five-year mortality risk was <5% in 60% of all patients, and in 30% of those aged over 60 years. Conclusions Viral replication, lower CD4 count, prior AIDS, and transmission via injecting drug use continue to predict higher all-cause and AIDS-related mortality in patients treated with combination antiretroviral therapy for over a decade. Deaths from AIDS and non-AIDS infection are less frequent than deaths from other non-AIDS causes. PMID:27525413

Assessment of emissions and removal of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) at start-up periods in a hazardous waste incinerator.

A study was conducted to observe the changes in polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/F) levels and congener profiles in the flue gas of a hazardous waste incinerator during two start-up periods. Flue gas samplings were performed simultaneously through Air Pollution Control Devices (APCDs) (including boiler outlet, electrostatic precipitator (ESP) outlet, wet scrubbers (WS) outlet, and activated carbon (AC) filter outlet) in different combustion temperatures during a planned cold (long) start-up and an unplanned warm (short) start-up. The results showed that PCDD/F concentrations could be elevated during the start-up periods up to levels 3-4 times higher than those observed in the normal operation. Especially lower combustion temperatures in the short start-ups may cause high PCDD/F concentrations in the raw flue gas. Assessment of combustion temperatures and Furans/Dioxins values indicated that surface-catalyzed de novo synthesis was the dominant pathway in the formation of PCDD/Fs in the combustion units. PCDD/F removal efficiencies of Air Pollution Control Devices suggested that formation by de novo synthesis existed in ESP also when in operation, leading to increase of gaseous phase PCDD/Fs in ESP Particle-bound PCDD/Fs were removed mainly by ESP and WS, while gaseous phase PCDD/Fs were removed by WS, and more efficiently by AC filter. This paper evaluates PCDD/F emissions and removal performances of APCDs (ESP, wet scrubbers, and activated carbon) during two start-up periods in an incinerator. The main implications are the following: (1) start-up periods increase PCDD/F emissions up to 2-3 times in the incinerator; (2) low combustion temperatures in start-ups cause high PCDD/F emissions in raw gas; (3) formation of PCDD/Fs by de novo synthesis occurs in ESP; (4) AC is efficient in removing gaseous PCDD/Fs, but may increase particle-bound ones; and (5) scrubbers remove both gaseous and particle-bound PCDD/Fs efficiently.

SOP 98-5 brings uniformity to reporting start-up costs.

Luecke, R W; Meeting, D T

1999-08-01

The American Institute of Certified Public Accountants (AICPA) issued Statement of Position (SOP) No. 98-5, Reporting on the Costs of Start-Up Activities, in April 1998 to provide organizations with guidance on how to report start-up and organization costs. Because some companies were expensing start-up costs while other companies were capitalizing start-up costs with a variety of periods over which to amortize costs, it was difficult to compare companies' financial statements. SOP No. 98-5 will bring uniformity to the treatment of start-up and organization costs by dictating that these costs be expensed as incurred. AICPA's Accounting Standards Executive Committee adopted an intentionally broad definition of start-up costs to capture the vast majority of costs associated with starting up an organization. SOP No. 98-5 takes effect for financial statements for fiscal years beginning after December 15, 1998, but can be applied earlier for fiscal years for which financial statements have not been issued.

Drug dependency may develop during long-term benzodiazepine use, indicated, for example, by dose escalation. The first benzodiazepine chosen may affect the risk of dose escalation. To detect possible differences in benzodiazepine use between new users of diazepam and oxazepam over time. This 5-year prescription database study included 19 747 new benzodiazepine users, inhabitants of Norway, aged 30-60 years, with first redemption for diazepam or oxazepam. Individuals starting on diazepam versus oxazepam were analysed by logistic regression with sex, age, other drug redemptions, prescriber's specialty, household income, education level, type of work, and vocational rehabilitation support as background variables. Time to reach a daily average intake of ≥1 defined daily doses (DDD) over a 3-month period was analysed using a Cox proportional hazard regression model. New users of oxazepam had a higher risk for dose escalation compared with new users of diazepam. This was true even when accounting for differences in sociodemographic status and previous drug use (hazard ratio [HR] 1.33, 95% confidence interval = 1.17 to 1.51). Most doctors prescribed, according to recommendations, oxazepam to individuals they may have regarded as prone to and at risk of dependency. However, these individuals were at higher risk for dose escalation even when accounting for differences in sociodemographic status and previous drug use. Differences between the two user groups could be explained by different preferences for starting drug, DDD for oxazepam being possibly too low, and some unaccounted differences in illness. © British Journal of General Practice 2016.

This study aimed to investigate biofilm properties evolution coupled with different ages during the start-up period in a moving bed biofilm reactor system. Physicochemical characteristics including adhesion force, extracellular polymeric substances (EPS), morphology as well as volatile solid and microbial community were studied. Results showed that the formation and development of biofilms exhibited four stages, including (I) initial attachment and young biofilm formation, (II) biofilms accumulation, (III) biofilm sloughing and updating, and (IV) biofilm maturation. During the whole start-up period, adhesion force was positively and significantly correlated with the contents of EPS, especially the content of polysaccharide. In addition, increased adhesion force and EPS were beneficial for biofilm retention. Gram-negative bacteria mainly including Sphaerotilus, Zoogloea and Haliscomenobacter were predominant in the initial stage. Actinobacteria was beneficial to resist sloughing. Furthermore, filamentous bacteria were dominant in maturation biofilm. Copyright © 2015 Elsevier Ltd. All rights reserved.

In a large unselected population of normal spontaneous pregnancies, to estimate the biologic variation of the interval from the first day of the last menstrual period to start of pregnancy, and the biologic variation of gestational length to delivery; and to estimate the random error of routine ultrasound assessment of gestational age in mid-second trimester. Cohort study of 11,238 singleton pregnancies, with spontaneous onset of labour and reliable last menstrual period. The day of delivery was predicted with two independent methods: According to the rule of Nägele and based on ultrasound examination in gestational weeks 17-19. For both methods, the mean difference between observed and predicted day of delivery was calculated. The variances of the differences were combined to estimate the variances of the two partitions of pregnancy. The biologic variation of the time from last menstrual period to pregnancy start was estimated to 7.0 days (standard deviation), and the standard deviation of the time to spontaneous delivery was estimated to 12.4 days. The estimate of the standard deviation of the random error of ultrasound assessed foetal age was 5.2 days. Even when the last menstrual period is reliable, the biologic variation of the time from last menstrual period to the real start of pregnancy is substantial, and must be taken into account. Reliable information about the first day of the last menstrual period is not equivalent with reliable information about the start of pregnancy.

We searched for quasi-periodicities on year-like timescales in the light curves of six blazars in the optical—near-infrared bands and we made a comparison with the high energy emission. We obtained optical/NIR light curves from Rapid Eye Mounting photometry plus archival Small and Moderate Aperture Research Telescope System data and we accessed the Fermi light curves for the γ-ray data. The periodograms often show strong peaks in the optical and γ-ray bands, which in some cases may be inter-related. The significance of the revealed peaks is then discussed, taking into account that the noise is frequency dependent. Quasi-periodicities on a year-likemore » timescale appear to occur often in blazars. No straightforward model describing these possible periodicities is yet available, but some plausible interpretations for the physical mechanisms causing periodic variabilities of these sources are examined.« less

The New International Sunspot Numbers (NISNs) have been successfully compiled and can be downloaded from the World Data Center-Sunspot index and Long-term Solar Observations, Royal Observatory of Belgium, Brussels. The periods in these NISNs have been studied by using the Lomb-Scargle periodogram. The results show that the international sunspot numbers have a lot of periods. Of the various periods, the most outstanding period around 11 year is 10.108 year after removing the 10.862 year signal from the time series of sunspot numbers, while the periods of 11.988 year, 7.990 year, 9.612 year, 5.445 year, 8.915 year, 5.792 year are also found with the period of 5.445 year being stronger than those of 5.792 year and 8.915 year. However, the period of 5.445 year is still much weaker than the period of 10.862 year. It is evident that the periods around 11 year and 5.5 year in the revised international sunspot numbers obtained by using the Lomb-Scargle periodogram method is somewhat different from the ones in previous studies.

After April of 2010, we have not obtained any enough budget for new instruments. Therefore, we have not been able to install new Flare Monitoring Telescopes (FMT) in new countries, such as Algeria. On the other hand, however, we have continued international academic exchange through scientific and educational collaboration with mainly Peru, such as data-analysis training, holding scientific workshops etc. Additionally, in this year, King Saudi University of Saudi Arabia and CRAAG of Algeria have planned to build a new FMT in their university by their own budget. Therefore, we have started some collaboration in the field of technical advices of instruments and scientific themes etc. Moreover, Pakistan Space and Upper Atmosphere Research Commission (SUPARCO) also offered us participation in the CHAIN-project. We would like to continue to consider the possibility of academic collaboration with such new positive developing nations, too.

In pregnant smoking cessation trial participants, to estimate (1) among women abstinent at the end of pregnancy, the proportion who re-start smoking at time-points afterwards (primary analysis) and (2) among all trial participants, the proportion smoking at the end of pregnancy and at selected time-points during the postpartum period (secondary analysis). Trials identified from two Cochrane reviews plus searches of Medline and EMBASE. Twenty-seven trials were included. The included trials were randomized or quasi-randomized trials of within-pregnancy cessation interventions given to smokers who reported abstinence both at end of pregnancy and at one or more defined time-points after birth. Outcomes were validated biochemically and self-reported continuous abstinence from smoking and 7-day point prevalence abstinence. The primary random-effects meta-analysis used longitudinal data to estimate mean pooled proportions of re-starting smoking; a secondary analysis used cross-sectional data to estimate the mean proportions smoking at different postpartum time-points. Subgroup analyses were performed on biochemically validated abstinence. The pooled mean proportion re-starting at 6 months postpartum was 43% [95% confidence interval (CI) = 16-72%, I(2)  = 96.7%] (11 trials, 571 abstinent women). The pooled mean proportion smoking at the end of pregnancy was 87% (95% CI = 84-90%, I(2)  = 93.2%) and 94% (95% CI = 92-96%, I(2)  = 88%) at 6 months postpartum (23 trials, 9262 trial participants). Findings were similar when using biochemically validated abstinence. In clinical trials of smoking cessation interventions during pregnancy only 13% are abstinent at term. Of these, 43% re-start by 6 months postpartum. © 2016 The Authors. Addiction published by John Wiley & Sons Ltd on behalf of Society for the Study of Addiction.

Bipolar femoral head arthroplasty in osteoarthritis. A prospective study with a minimum 5-year follow-up period.

Pandit, R

1996-08-01

Primary bipolar femoral head arthroplasties performed on 100 osteoarthritic hips were studied to a minimum of 5 years after surgery. All arthroplasties were performed on physically active patients. At a mean follow-up period of 5.5 years, The Hospital for Special Surgery hip scores were good to excellent in 96 hips. Transient startup soreness constituted the most frequent complaint, occurring in 34 hips. Three hips had more persistent pain localized to the acetabulum, necessitating revision to fixed sockets, which alleviated the symptoms. Four additional hips, in heavy, active men, developed polyethylene fatigue fracture and component disassembly. Acetabular migration of more than 5 mm developed in one hip. Motion, as determined radiologically, occurred primarily at the inner bearing. There were no dislocations or infections in the series. The Bateman bipolar prosthesis provides generally good results in osteoarthritic hips. The shorter operating time and the case of revision are special advantages of bipolar devices. Start-up soreness and stiffness is a shortcoming in approximately one third of cases. Component disassembly in heavy, active men is a problem and the bipolar arthroplasty should be avoided in these patients. Start-up soreness was a significant problem in particular.

Intraosseous hemangiomas in the jaws are rare lesions and may lead to several complications. The authors present a case of a 12-year-old girl with a radiolucent periapical lesion between tooth 35 and 36 where nocturnal exsanguinating bleeding started to occur from periodontal sulcus during orthodontic treatment. Diagnosis of an intraosseous hemangioma in the mandible was based on positive needle aspiration for blood, computed tomography and arteriography. At first the family chose to only follow-up the lesion but episodes of nocturnal hemorrhage were becoming more frequent and a treatment was requested. Embolization and dental extraction were performed in order to treat the lesion. After a follow-up period of 17 years no more cases of hemorrhage occurred and lesion regressed.

Critical periods and amblyopia.

PubMed

Daw, N W

1998-04-01

During the past 20 years, basic science has shown that there are different critical periods for different visual functions during the development of the visual system. Visual functions processed at higher anatomical levels within the system have a later critical period than functions processed at lower levels. This general principle suggests that treatments for amblyopia should be followed in a logical sequence, with treatment for each visual function to be started before its critical period is over. However, critical periods for some visual functions, such as stereopsis, are not yet fully determined, and the optimal treatment is, therefore, unknown. This article summarizes the current extent of our knowledge and points to the gaps that need to be filled.

Ansari, Arya; Purtell, Kelly; Gershoff, Elizabeth

2015-01-01

The federal Head Start program, designed to improve the school readiness of children from low-income families, often serves 3- and 4-year-old children in the same classrooms. Given the developmental differences between 3 and 4 year olds, it is unknown if educating them together in the same classrooms benefits one, both, or neither. Using data from the Family and Child Experiences Survey 2009 cohort, this study leveraged a peer effects framework to examine the associations between mixed-age classrooms and the school readiness of a nationally representative sample of newly enrolled 3- (n= 1,644) and 4-year-old (n= 1,185) Head Start children. Results revealed that 4-year-old children displayed fewer gains in academic skills during the preschool year when they were enrolled in classrooms with a greater number of 3 year olds; effect sizes corresponded to four-to-five months of academic development. In contrast, classroom age composition was not consistently associated with 3-year-old's school readiness. PMID:26566635

Background Health systems with limited resources may have the greatest impact on suicide if their prevention efforts target the highest-risk treatment groups during the highest-risk periods. To date, few health systems have carefully segmented their depression treatment populations by level of risk and prioritized prevention efforts on this basis. Methods We conducted a retrospective cohort study of 887,859 VA patients receiving depression treatment between 4/1/1999 and 9/30/2004. We calculated suicide rates for five sequential 12-week periods following treatment events that health systems could readily identify: psychiatric hospitalizations, new antidepressant starts (>6 months without fills), “other” antidepressant starts, and dose changes. Using piecewise exponential models, we examined whether rates differed across time-periods. We also examined whether suicide rates differed by age-group in these periods. Results Over all time periods, the suicide rate was 114/100,000 person-years (95% CI; 108,120). In the first 12-week periods, suicide rates were: 568/100,000 p-y (95% CI; 493,651) following psychiatric hospitalizations; 210/100,000 p-y (95% CI; 187, 236) following new antidepressant starts; 193/100,000 p-y (95% CI; 167, 222) following other starts; and 154/100,000 p-y (95% CI; 133, 177) following dose changes. Suicide rates remained above the base rate for 48 weeks following hospital discharge and 12 weeks following antidepressant events. Adults aged 61–80 years were at highest risk in the first 12-weeks periods Conclusions To have the greatest impact on suicide, health systems should prioritize prevention efforts following psychiatric hospitalizations. If resources allow, closer monitoring may also be warranted in the first 12 weeks following antidepressant starts, across all age-groups. PMID:18945495

Mannheimia haemolytica isolated from feedlot cattle were tested for tulathromycin resistance. Cattle were sampled over a 3-year period, starting 12 months after approval of tulathromycin for prevention and treatment of bovine respiratory disease. Nasopharyngeal samples from approximately 5,814 cattle were collected when cattle entered feedlots (N = 4) and again from the same cattle after ≥60 days on feed. The antimicrobial use history for each animal was recorded. Mannheimia haemolytica was isolated from 796 (13.7%) entry samples and 1,038 (20.6%) ≥ 60 days samples. Of the cattle positive for M. haemolytica, 18.5, 2.9, and 2.4% were administered therapeutic concentrations of tulathromycin, tilmicosin, or tylosin tartrate, respectively. In addition, 13.2% were administered subtherapeutic concentrations of tylosin phosphate in feed. In years one and two, no tulathromycin-resistant M. haemolytica were detected, whereas five isolates (0.4%) were resistant in year three. These resistant isolates were collected from three cattle originating from a single pen, were all serotype 1, and were genetically related (≥89% similarity) according to pulsed-field gel electrophoreses patterns. The five tulathromycin-resistant isolates were multi-drug resistant also exhibiting resistance to oxytetracycline, tilmicosin, ampicillin, or penicillin. The macrolide resistance genes erm(42), erm(A), erm(B), erm(F), erm(X) and msr(E)-mph(E), were not detected in the tulathromycin-resistant M. haemolytica. This study showed that tulathromycin resistance in M. haemolytica from a general population of feedlot cattle in western Canada was low and did not change over a 3-year period after tulathromycin was approved for use in cattle.

In this poster we applied the moving window approach (see Poster I of this collection) to analyze trends of autumn and its corresponding months (September, October, November) temperature mean values of maximum (Tmax) and minimum (Tmin) in Spanish mainland to detect the effects of length period and starting year. Monthly series belong to Monthly Temperature dataset of Spanish mainland (MOTEDAS). Database contains in its grid format of 5236 pixels of monthly series (10x10 km). The threshold used in spatial analyses considers 20% of land under significant trend (p<0.05). The most striking results are as follow: • Seasonal trend analyses of Autumn Tmax show no significance at any temporal Windows. Trends of Tmin are significant in more than 20% of land until 1974-2010. The area affected in Tmin progressively increase from SE to NW. • Monthly trend analyses not detect any significance in Tmax, while in Tmin, particularly in October, an extended area is detected in temporal windows in between 1951-2010 to 1978-2010, but clearly concentrated in the starting years of initial 70´s. Spatial pattern of areas affected significantly seems to be from SE to NW for October, and South-North in September. To conclude autumn trend analyses of Tmax and Tmin in Spanish mainland only detect significant trend in Tmin, mostly located in the 70´s and extending from SE to central areas of study area.

We investigated the epidemiology of total Achilles tendon ruptures and complication rates after operative and nonoperative treatments over a 33-year period in Oulu, Finland. Patients with Achilles tendon ruptures from 1979 to 2011 in Oulu were identified from hospital patient records. Demographic data, treatment method, and complications were collected retrospectively from medical records. Overall and sex- and age-specific incidence rates were calculated with 95% confidence intervals (CIs). The overall incidence per 100,000 person-years increased from 2.1 (95% CI 0.3-7.7) in 1979 to 21.5 (95% CI 14.6-30.6) in 2011. The incidence increased in all age groups. The mean annual increase in incidence was 2.4% (95% CI 1.3-4.7) higher for non-sports-related ruptures than for sports-related ruptures (P = 0.036). The incidence of sports-related ruptures increased during the second 11-year period whereas the incidence of non-sports-related ruptures increased steadily over the entire study period. Infection was four times more common after operative treatment compared with nonoperative treatment, re-rupture rates were similar. The incidence of Achilles tendon ruptures increased in all age groups over a 33-year period. Increases were mainly due to sports-related injuries in the second 11-year period and non-sports-related injuries in the last 11-year period. © 2014 John Wiley & Sons A/S.

It is of interest to understand how insulin therapy currently evolves in clinical practice, in the years after starting insulin in people with type 2 diabetes. We aimed to describe this evolution prospectively over 4 years, to assist health care planning. People who had started any insulin were identified from 12 countries on three continents. Baseline, then yearly follow-up, data were extracted from clinical records over 4 years. Of the 2999 eligible people, 2272 were followed over 4 years. When starting insulin, mean (SD) duration of diabetes was 10.6 (7.8) years, HbA1c 9.5 (2.0)% (80 [22]mmol/mol) and BMI 29.3 (6.3)kg/m(2). Initial insulin therapy was basal 52%, premix 23%, mealtime+basal 14%, mealtime 8% and other 3%; at 4 years, 30%, 25%, 33%, 2% and 5%, respectively, with 5% not on insulin. Insulin dose was 20.2U/day at the start and 45.8U/day at year 4. There were 1258 people (55%) on their original regimen at 4 years, and this percentage differed according to baseline insulin regimen. HbA1c change was -2.0 (2.2)% (-22 [24]mmol/mol) and was similar by final insulin regimen. Hypoglycaemia prevalence was <20% in years 1-4. Body weight change was mostly in year 1, and was very variable, mean +2.7 (7.5)kg at year 4. Different insulin regimens were started in people with differing characteristics, and they evolved differently; insulin dose, hypoglycaemia and body weight change were diverse and largely independent of regimen.

On-time starts for the first case of the day are critical to maintaining efficiency in operating rooms (ORs). We studied whether a resident-led initiative to ensure on-time site marking and documentation of surgical consent could lead to improved first-case start time. In a resident-led initiative at a large 600-bed academic hospital with 25 ORs, we aimed to complete site marking and surgical consents half an hour before the scheduled start time for all first-case neurosurgical patients. We monitored the occurrence of delayed first starts and the length of delay during our initiative, and compared these cases to neurosurgical cases 3 months before the implementation of the initiative and to first-start nonneurosurgical cases. In the year of the initiative, both site marking and surgical consents were completed 30 minutes before the case start in 97% of neurosurgical cases. The average delay across all first-case starts was reduced to 7.17 minutes (N = 1271), compared with 9.67 minutes before the intervention (N = 345). During the study period, non-neurosurgical cases were delayed on average 10.3 minutes (N = 3592). There was a significant difference in latencies between the study period and the period before the initiative (p < 0.001), and also between neurosurgical cases and nonneurosurgical cases (p < 0.001). There was no reduction in delay times seen on the non-neurosurgical services in the study period when compared to the case 3 months before. Considering its effect across 1271 cases, this initiative over 1 year resulted in a total reduction of 52 hours and 57 minutes in delays. Through a resident-led quality improvement program, neurosurgical trainees successfully reduced delays in first-case starts on a surgical service. Engaging physician trainees in quality improvement and enhancing OR efficiency can be successfully achieved and can have a significant clinical and financial effect.

The Interplanetary Monitoring Platform 8 (IMP-8) and Voyager 2 spacecraft have recently detected a very strong modulation in the solar wind speed with an approximately 1.3 year period. Combined with evidence from long-term auroral and magnetometer studies, this suggests that fundamental changes in the Sun occur on a roughly 1.3 year time scale.

To assess the prevalence of the main causes of morbi-mortality in the antiphospholipid syndrome (APS) during a 10-year-follow-up period and to compare the frequency of early manifestations with those that appeared later. In 1999, we started an observational study of 1000 APS patients from 13 European countries. All had medical histories documented when entered into the study and were followed prospectively during the ensuing 10 years. 53.1% of the patients had primary APS, 36.2% had APS associated with systemic lupus erythematosus and 10.7% APS associated with other diseases. Thrombotic events appeared in 166 (16.6%) patients during the first 5-year period and in 115 (14.4%) during the second 5-year period. The most common events were strokes, transient ischaemic attacks, deep vein thromboses and pulmonary embolism. 127 (15.5%) women became pregnant (188 pregnancies) and 72.9% of pregnancies succeeded in having one or more live births. The most common obstetric complication was early pregnancy loss (16.5% of the pregnancies). Intrauterine growth restriction (26.3% of the total live births) and prematurity (48.2%) were the most frequent fetal morbidities. 93 (9.3%) patients died and the most frequent causes of death were severe thrombosis (36.5%) and infections (26.9%). Nine (0.9%) cases of catastrophic APS occurred and 5 (55.6%) of them died. The survival probability at 10 years was 90.7%. Patients with APS still develop significant morbidity and mortality despite current treatment. It is imperative to increase the efforts in determining optimal prognostic markers and therapeutic measures to prevent these complications. Published by the BMJ Publishing Group Limited.

is well established that warming leads to longer growing seasons in seasonally cold ecosystems. Whether this goes along with an increase in the net ecosystem carbon dioxide (CO2) uptake is much more controversial. We studied the effects of warming on the start of the carbon uptake period (CUP) of three mountain grasslands situated along an elevational gradient in the Alps. To this end, we used a simple empirical model of the net ecosystem CO2 exchange, calibrated, and forced with multiyear empirical data from each site. We show that reductions in the quantity and duration of daylight associated with earlier snowmelts were responsible for diminishing returns, in terms of carbon gain, from longer growing seasons caused by reductions in daytime photosynthetic uptake and increases in nighttime losses of CO2. This effect was less pronounced at high, compared to low, elevations, where the start of the CUP occurred closer to the summer solstice when changes in day length and incident radiation are minimal.

The temporal and spatial structure of 332 404 daily fire-start records from the western United States for the period 1986 through 1996 is illustrated using several complimentary visualisation techniques. We supplement maps and time series plots with Hovmo??ller diagrams that reduce the spatial dimensionality of the daily data in order to reveal the underlying space?time structure. The mapped distributions of all lightning- and human-started fires during the 11-year interval show similar first-order patterns that reflect the broad-scale distribution of vegetation across the West and the annual cycle of climate. Lightning-started fires are concentrated in the summer half-year and occur in widespread outbreaks that last a few days and reflect coherent weather-related controls. In contrast, fires started by humans occur throughout the year and tend to be concentrated in regions surrounding large-population centres or intensive-agricultural areas. Although the primary controls of human-started fires are their location relative to burnable fuel and the level of human activity, spatially coherent, weather-related variations in their incidence can also be noted. ??

Evapotranspiration response to multi-year dry periods in the semi-arid western United States

NASA Astrophysics Data System (ADS)

Rungee, J. P., II; Bales, R. C.

2017-12-01

Analysis of measured evapotranspiration shows multi-year regolith water storage can support evapotranspiration for years into a multi-year dry period. Measurements at 25 flux-tower sites in the semi-arid western United States, distributed across five primary land-cover types, show both resilience and vulnerability to multi-year dry periods. Average evapotranspiration ranged from about 700+200 mm per water year (October-September) in evergreen needleleaf forests to 350+150 mm per water year in grasslands and open shrublands. On average, in California's Mediterranean climate almost half of the water-year evapotranspiration is supported by seasonal and/or multi-year regolith water storage, compared to a characteristic 20 to 30 percent value of energy-limited and inland sites. Below 35oN latitude, water-year evapotranspiration exceeded estimated precipitation in over half of the years on record. For non-energy-limited sites, water-year evapotranspiration increased with precipitation up to a maximum water-year evapotranspiration value of about 900, 750, 600, 425 and 300 mm per water year for evergreen needleleaf forests, mixed forests, woody savannas, grasslands and open shrublands, respectively. There were 15 multi-year dry periods on record that exhibited either an attenuation in evapotranspiration, defined as an annual value below 80% of the wet-year average, or withdrawal from multi-year storage. A multi-year dry period was defined as three or more consecutive water years in which all water-year precipitation values and the mean period value were in the lower 50 and 35 percent of the historical record, respectively. For sites exhibiting evapotranspiration attenuation, resistance to multi-year dry periods ranged from 9 to 49 months, drafting as much as 444 mm of regolith storage. At some mountain sites regolith storage provided up to 678 mm, almost the equivalent of the average water-year evapotranspiration for these sites, over the extent of the multi-year dry

To determine the annual incidence of visual impairment in a Japanese population during a 10-year period. We examined the physical disability certificates issued yearly between 2004 and 2013 in Mie prefecture, Japan. During this period 2468 visually impaired people were registered under the newly defined Act on Welfare of the Physically Disabled Persons' criteria. The age, sex distribution, and causes of visual impairment were determined from the certificates. The major causes of visual impairment during the ten-year period were glaucoma (23.3%), diabetic retinopathy (17.3%), retinitis pigmentosa (12.2%), macular degeneration (9.0%), chorioretinal degeneration or high myopia (7.4%), optic atrophy (5.8%), stroke or brain tumor (5.4%) and cataracts (3.7%). The incidence of glaucoma was significantly higher throughout the period (2004-2013), and that of diabetic retinopathy was lower between 2007 and 2013. The incidence of retinitis pigmentosa did not change significantly during the 10-year period. The incidence of macular degeneration tended to increase between 2004 and 2007, but it decreased significantly between 2007 and 2013. The results indicate that in Japan, the rates of the major causes of visual impairment altered in the most recent 10-year period reflecting the recent changes in the social background and advances in ocular and systemic treatment.

in major urban areas in the San Joaquin Valley (SJV) and South Coast Air Basin (SoCAB). These changes lead to a predicted decrease in PM2.5 mass concentrations of ~0.3-0.7 μg m-3 in the southern portion of the SJV and ~0.3-1.1 μg m-3 along coastal regions of California including the heavily populated San Francisco Bay Area and the SoCAB surrounding Los Angeles. Annual average PM2.5 concentrations were predicted to increase at certain locations within the SJV and the Sacramento Valley (SV) due to the effects of climate change, but a corresponding analysis of the annual variability showed that these predictions are not statistically significant (i.e. the choice of a different 7-year period could produce a different outcome for these regions). Overall, virtually no region in California outside of coastal + central Los Angeles, and a small region around the port of Oakland in the San Francisco Bay Area experienced a statistically significant change in annual average PM2.5 concentrations due to the effects of climate change in the present~study. The present study employs the highest spatial resolution (8 km) and the longest analysis windows (7 years) of any climate-air quality analysis conducted for California to date, but the results still have some degree of uncertainty. Most significantly, GCM calculations have inherent uncertainty that is not fully represented in the current study since a single GCM was used as the starting point for all calculations. The PCM results used in the current study predicted greater wintertime increases in air temperature over the Pacific Ocean than over land, further motivating comparison to other GCM results. Ensembles of GCM results are usually employed to build confidence in climate calculations. The current results provide a first data-point for the climate-air quality analysis that simultaneously employ the fine spatial resolution and long time scales needed to capture the behavior of climate-PM2.5 interactions in California.

German medical faculties currently have severe financial problems. There is the conflict between financing teaching medical students, inpatient and outpatient costs and supporting basic and applied research. Young postdocs can apply for a grant to start research projects to establish techniques on publishing data as a basis for applying for grants from the German Research Foundation or foundations with a critical review system. Successful applicants from the years 1998-2011 were asked to answer a questionnaire. The annual number of applications ranged from 28 to 96 per year. Within the first period of our analysis ranging from 1998 to 2004, a mean number of 69.5 % ± 14.0 % of submitted grant applications were approved annually in comparison to an average approval of 30.9 % ± 11 % in the years 2006-2001. In total 353 projects were funded with a mean amount of money for a project of approximately 18,640 EUR. The mean amount of external grant money following the start-up period was 7.2 times the money initially spent. That is an excellent return of investment. There were no differences between applicants from the department of surgery or department of internal medicine. In the meantime, 56 % of men and 42 % of women have achieved the academic degree university lecturer (privatdozent). Furthermore, 71 % of the participants evaluated this start-up research as supportive for their postdoctoral qualification (habilitation). The program for initial investment for young postdocs by internal start-up grants is overall successful.

Start-up capabilities of photovoltaic module for the International Space Station

Hajela, G.; Hague, L.

1997-12-31

The International Space Station (ISS) uses four photovoltaic modules (PVMs) to supply electric power for the US On-Orbit Segment (USOS). The ISS is assembled on orbit over a period of about 5 years and over 40 stages. PVMs are launched and integrated with the ISS at different times during the ISS assembly. During early stages, the electric power is provided by the integrated truss segment (ITS) P6; subsequently, ITS P4, S4, and S6 are launched. PVMs are launched into space in the National Space Transportation System (NSTS) cargo bay. Each PVM consists of two independent power channels. The NSTS docksmore » with the ISS, the PVM is removed from the cargo bay and installed on the ISS. At this stage the PVM is in stowed configuration and its batteries are in fully discharged state. The start-up consists of initialization and checkout of all hardware, deployment of SAW and photovoltaic radiator (PVR), thermal conditioning batteries, and charging batteries; not necessarily in the same order for all PVMs. PVMs are designed to be capable of on-orbit start-up, within a specified time period, when external power is applied to a specified electrical interface. This paper describes the essential steps required for PVM start-up and how these operations are performed for various PVMs. The integrated operations scenarios (IOS) prepared by the NASA, Johnson Space Center, details specific procedures and timelines for start-up of each PVM. The paper describes how dormant batteries are brought to their normal operating temperature range and then charged to 100% state of charge (SOC). Total time required to complete start-up is computed and compared to the IOS timelines.

One hundred years of return period: Strengths and limitations

One hundred years from its original definition by Fuller, the probabilistic concept of return period is widely used in hydrology as well as in other disciplines of geosciences to give an indication on critical event rareness. This concept gains its popularity, especially in engineering practice for design and risk assessment, due to its ease of use and understanding; however, return period relies on some basic assumptions that should be satisfied for a correct application of this statistical tool. Indeed, conventional frequency analysis in hydrology is performed by assuming as necessary conditions that extreme events arise from a stationary distribution and are independent of one another. The main objective of this paper is to investigate the properties of return period when the independence condition is omitted; hence, we explore how the different definitions of return period available in literature affect results of frequency analysis for processes correlated in time. We demonstrate that, for stationary processes, the independence condition is not necessary in order to apply the classical equation of return period (i.e., the inverse of exceedance probability). On the other hand, we show that the time-correlation structure of hydrological processes modifies the shape of the distribution function of which the return period represents the first moment. This implies that, in the context of time-dependent processes, the return period might not represent an exhaustive measure of the probability of failure, and that its blind application could lead to misleading results. To overcome this problem, we introduce the concept of Equivalent Return Period, which controls the probability of failure still preserving the virtue of effectively communicating the event rareness.

Changes in vegetative growing seasons are dominant indicators of the dynamic response of ecosystems to climate change. Therefore, knowledge of growing seasons over the past decades is essential to predict ecosystem changes. In this study, the long-term changes in the growing seasons of temperate vegetation over the Northern Hemisphere were examined by analyzing satellite-measured normalized difference vegetation index and reanalysis temperature during 1982 2008. Results showed that the length of the growing season (LOS) increased over the analysis period; however, the role of changes at the start of the growing season (SOS) and at the end of the growing season (EOS) differed depending on the time period. On a hemispheric scale, SOS advanced by 5.2 days in the early period (1982-1999) but advanced by only 0.2 days in the later period (2000-2008). EOS was delayed by 4.3 days in the early period, and it was further delayed by another 2.3 days in the later period. The difference between SOS and EOS in the later period was due to less warming during the preseason (January-April) before SOS compared with the magnitude of warming in the preseason (June September) before EOS. At a regional scale, delayed EOS in later periods was shown. In North America, EOS was delayed by 8.1 days in the early period and delayed by another 1.3 days in the later period. In Europe, the delayed EOS by 8.2 days was more significant than the advanced SOS by 3.2 days in the later period. However, in East Asia, the overall increase in LOS during the early period was weakened in the later period. Admitting regional heterogeneity, changes in hemispheric features suggest that the longer-lasting vegetation growth in recent decades can be attributed to extended leaf senescence in autumn rather than earlier spring leaf-out.

The possible effect of radiofrequency exposure from mobile phones on tumor risk has been studied since the late 1990s. Yet, empirical information about recall of the start of mobile phone use among adult cases and controls has never been reported. Limited knowledge about recall errors hampers interpretations of the epidemiological evidence. We used network operator data to validate the self-reported start year of mobile phone use in a case-control study of mobile phone use and acoustic neuroma risk. The answers of 96 (29%) cases and 111 (22%) controls could be included in the validation. The larger proportion of cases reflects a more complete and detailed reporting of subscription history. Misclassification was substantial, with large random errors, small systematic errors, and no significant differences between cases and controls. The average difference between self-reported and operator start year was -0.62 (95% confidence interval: -1.42, 0.17) years for cases and -0.71 (-1.50, 0.07) years for controls, standard deviations were 3.92 and 4.17 years, respectively. Agreement between self-reported and operator-recorded data categorized into short, intermediate and long-term use was moderate (kappa statistic: 0.42). Should an association exist, dilution of risk estimates and distortion of exposure-response patterns for time since first mobile phone use could result from the large random errors in self-reported start year. Retrospective collection of operator data likely leads to a selection of "good reporters", with a higher proportion of cases. Thus, differential recall cannot be entirely excluded.

Solar wind variations in the 60-100 year period range: A review

NASA Technical Reports Server (NTRS)

Feynman, J.

1983-01-01

The evidence for and against the reality of a solar wind variation in the period range of 60-100 years is reexamined. Six data sets are reviewed; sunspot numbers, geomagnetic variations, two auroral data sets and two (14)C data sets. These data are proxies for several different aspects of the solar wind and the presence or absence of 60-100 year cyclic behavior in a particular data set does not necessarily imply the presence or absence of this variation in other sets. It was concluded that two different analyses of proxy data for a particular characteristic of the heliospheric solar wind yielded conflicting results. This conflict can be resolved only by future research. It is also definitely confirmed that proxy data for the solar wind in the ecliptic at 1 A.U. undergo a periodic variation with a period of approximately 87 years. The average amplitude and phase of this variation as seen in eleven cycles of proxy data are presented.

To evaluate the impact of the nature of the support material on its colonization by a methanogenic consortium, four substrata made of different materials: polyvinyl chloride, 2 polyethylene and polypropylene were tested during the start-up of lab-scale fixed-film reactors. The reactor performances were evaluated and compared together with the analysis of the biofilms. Biofilm growth was quantified and the structure of bacterial and archaeal communities were characterized by molecular fingerprinting profiles (capillary electrophoresis-single strand conformation polymorphism). The composition of the inoculum was shown to have a major impact on the bacterial composition of the biofilm, whatever the nature of the support material or the organic loading rate applied to the reactors during the start-up period. In contrast, the biofilm archaeal populations were independent of the inoculum used but highly dependent on the support material. Supports favouring Archaea colonization, the limiting factor in the overall process, should be preferred. PMID:24612643

Relationship Between Vertical Jump Height and Swimming Start Performance Before and After an Altitude Training Camp.

This study aimed (a) to analyze the development in the squat jump height and swimming start performance after an altitude training camp, (b) to correlate the jump height and swimming start performance before and after the altitude training period, and (c) to correlate the percent change in the squat jump height with the percent change in swimming start performance. Fifteen elite male swimmers from the Spanish Junior National Team (17.1 ± 0.8 years) were tested before and after a 17-day training camp at moderate altitude. The height reached in the squat jump exercise with additional loads of 0, 25, 50, 75, and 100% of swimmers' pretest body weight and swimming start performance (time to 5, 10, and 15 m) were the dependent variables analyzed. Significant increases in the jump height (p ≤ 0.05; effect size [ES]: 0.35-0.48) and swimming start performance (p < 0.01; ES: 0.48-0.52) after the training period were observed. The start time had similar correlations with the jump height before training (r = -0.56 to -0.77) and after training (r = -0.50 to -0.71). The change in the squat jump height was inversely correlated with the change in the start time at 5 m (r = -0.47), 10 m (r = -0.73), and 15 m (r = -0.62). These results suggest that altitude training can be suitable to enhance explosive performance. The correlations obtained between the squat jump height and start time in the raw and change scores confirm the relevance of having high levels of lower-body muscular power to optimize swimming start performance.

Decomposing vertebrate cadavers release large, localized inputs of nutrients. These temporally limited resource patches affect nutrient cycling and soil organisms. The impact of decomposing cadavers on soil chemistry is relevant to soil biology, as a natural disturbance, and forensic science, to estimate the postmortem interval. However, cadaver impacts on soils are rarely studied, making it difficult to identify common patterns. We investigated the effects of decomposing pig cadavers (Sus scrofa domesticus) on soil chemistry (pH, ammonium, nitrate, nitrogen, phosphorous, potassium and carbon) over a one-year period in a spruce-dominant forest. Four treatments were applied, each with five replicates: two treatments including pig cadavers (placed on the ground and hung one metre above ground) and two controls (bare soil and bags filled with soil placed on the ground i.e. "fake pig" treatment). In the first two months (15-59 days after the start of the experiment), cadavers caused significant increases of ammonium, nitrogen, phosphorous and potassium (p<0.05) whereas nitrate significantly increased towards the end of the study (263-367 days; p<0.05). Soil pH increased significantly at first and then decreased significantly at the end of the experiment. After one year, some markers returned to basal levels (i.e. not significantly different from control plots), whereas others were still significantly different. Based on these response patterns and in comparison with previous studies, we define three categories of chemical markers that may have the potential to date the time since death: early peak markers (EPM), late peak markers (LPM) and late decrease markers (LDM). The marker categories will enhance our understanding of soil processes and can be highly useful when changes in soil chemistry are related to changes in the composition of soil organism communities. For actual casework further studies and more data are necessary to refine the marker categories along a

Starting Block Performance in Sprinters: A Statistical Method for Identifying Discriminative Parameters of the Performance and an Analysis of the Effect of Providing Feedback over a 6-Week Period

2005-01-01

The purpose of this study was twofold: (a) to examine if kinetic and kinematic parameters of the sprint start could differentiate elite from sub-elite sprinters and, (b) to investigate whether providing feedback (FB) about selected parameters could improve starting block performance of intermediate sprinters over a 6-week training period. Twelve male sprinters, assigned to an elite or a sub-elite group, participated in Experiment 1. Eight intermediate sprinters participated in Experiment 2. All athletes were required to perform three sprint starts at maximum intensity followed by a 10-m run. To detect differences between elite and sub-elite groups, comparisons were made using t-tests for independent samples. Parameters reaching a significant group difference were retained for the linear discriminant analysis (LDA). The LDA yielded four discriminative kinetic parameters. Feedback about these selected parameters was given to sprinters in Experiment 2. For this experiment, data acquisition was divided into three periods. The first six sessions were without specific FB, whereas the following six sessions were enriched by kinetic FB. Finally, athletes underwent a retention session (without FB) 4 weeks after the twelfth session. Even though differences were found in the time to front peak force, the time to rear peak force, and the front peak force in the retention session, the results of the present study showed that providing FB about selected kinetic parameters differentiating elite from sub-elite sprinters did not improve the starting block performance of intermediate sprinters. Key Points The linear discriminative analysis allows the identification of starting block parameters differentiating elite from sub-elite athletes. 6-week of feedback does not alter starting block performance in training context. The present results failed to confirm previous studies since feedback did not improve targeted kinetic parameters of the complex motor task in real-world context

2016-08-01

We present an analysis of 43 years (1972 to 2015) of spectroscopic observations of the Seyfert 1 galaxy NGC 5548. This includes 12 years of new unpublished observations (2003 to 2015). We compiled about 1600 Hβ spectra and analyzed the long-term spectral variations of the 5100 Å continuum and the Hβ line. Our analysis is based on standard procedures, including the Lomb-Scargle method, which is known to be rather limited to such heterogeneous data sets, and a new method developed specifically for this project that is more robust and reveals a ˜5700 day periodicity in the continuum light curve, the Hβ light curve, and the radial velocity curve of the red wing of the Hβ line. The data are consistent with orbital motion inside the broad emission line region of the source. We discuss several possible mechanisms that can explain this periodicity, including orbiting dusty and dust-free clouds, a binary black hole system, tidal disruption events, and the effect of an orbiting star periodically passing through an accretion disk.

Intermittent cholestatic liver disease may indicate an inherited deficiency of bile salt transport proteins. Episodes of cholestasis may start during pregnancy or during use of oral contraceptives or other medication. We describe the case of a 22-year-old mother with increasing jaundice and severe pruritus two weeks after starting hormonal contraception. A few months before she was suffering from intrahepatic cholestasis of pregnancy (ICP). Liver biopsy showed bland cholestasis with canalicular bile plugs. Treatment with ursodeoxycholic acid was not effective. Finally, rifampicin induced a complete remission of the cholestasis. Genetic testing showed a heterozygous mutation in the ABCB11 gene encoding the bile salt export pump (BSEP). Rifampicin activates nuclear receptors and may induce alternative pathways for the excretion of bile salts in patients with ABCB11 deficiency. © Georg Thieme Verlag KG Stuttgart · New York.

To compare one-year outcomes of women started on antiretroviral therapy (ART) during pregnancy in the pre-Option B+ era to those in the Option B+ era. A retrospective chart review was performed at three sites in Malawi. Women were included in the 'pre-Option B+' cohort if they started ART during pregnancy for a CD4 count < 350 cells/mm 3 or WHO 3/4 condition and in the 'Option B+' cohort if they started ART during pregnancy regardless of CD4 count or clinical stage. One-year outcomes were compared using Fisher's exact and ANOVA F-tests. A higher proportion of women in the pre-Option B+ cohort started ART at WHO stage 3/4 (11.9% versus 1.1%, P < 0.001), switched ART regimens (5.9% versus 0%, P = 0.002), or died in the first year after starting treatment (3.9% versus .5%, P = 0.05). While more women in the Option B+ cohort had poor adherence or defaulted, these differences were not significant. At our study sites, the transition to Option B+ has been associated with ART initiation in women with less advanced HIV infection, improved medication tolerability, and lower mortality. Further research is needed to better understand outcomes of Option B+.

Early Head Start, a federal program begun in 1995 for low-income pregnant women and families with infants and toddlers, was evaluated through a randomized trial of 3,001 families in 17 programs. Interviews with primary caregivers, child assessments, and observations of parent-child interactions were completed when children were 3 years old. Caregivers were diverse in race-ethnicity, language, and other characteristics. Regression-adjusted impact analyses showed that 3-year-old program children performed better than did control children in cognitive and language development, displayed higher emotional engagement of the parent and sustained attention with play objects, and were lower in aggressive behavior. Compared with controls, Early Head Start parents were more emotionally supportive, provided more language and learning stimulation, read to their children more, and spanked less. The strongest and most numerous impacts were for programs that offered a mix of home-visiting and center-based services and that fully implemented the performance standards early.

The effect of length and starting year on trend analyses of temperatures in Spanish mainland (1951-2010). Seasonal analysis: Winter (II)

In this poster we applied the moving window approach (see Poster I of this collection) to analyze trends of winter and its corresponding months (December, January, February) temperature mean values of maximum (Tmax) and minimum (Tmin) in Spanish mainland to detect the effects of length period and starting year. Monthly series belong to Monthly Temperature dataset of Spanish mainland (MOTEDAS). Database contains in its grid format of 5236 pixels of monthly series (10x10 km). The threshold used in spatial analyses considers 20% of land under significant trend (p<0.05). The most striking results are as follow: • Seasonal trend analyses of Tmax shows that global trend 1951-2010 was positive and significant mostly in central-western areas; from 1970 to 2010 there is less than 20% of land with significant trend. In the case of Tmin no relevant significant period is detected. • Monthly Tmax analyses show that December significant trend changed from positive (>20%) in between 1955-2010 until 1962-2010, to negative from 1976-2010. Meanwhile January does not show relevant period with significant trend; finally Tmax in February shows different periods with positive significant trend (>20% of land) 1951-2010 to 1954-2010 and 1962-2010 to 1968-2010. No significant trend is detected after this data. • Monthly Tmin trend analyses show that except exceptional period, no months present any significant trend. As conclusions, we have detected that for winter and winter-months, Tmax trends are not significant from 1970 across Spanish mainland. In the case of Tmin we conclude that no significant trend have been occurred in any temporal windows analyzed. Results differ from what traditionally has been assumed that the increase of the average annual temperature was due to the increase of trends in the winter season. And these analyses also show that seasonal trend values could hide monthly behavior. So extreme caution should be taken into account when seasonal values are offered.

Previous studies have shown that it is possible to detect macroscopic patterns of cultural change over periods of centuries by analyzing large textual time series, specifically digitized books. This method promises to empower scholars with a quantitative and data-driven tool to study culture and society, but its power has been limited by the use of data from books and simple analytics based essentially on word counts. This study addresses these problems by assembling a vast corpus of regional newspapers from the United Kingdom, incorporating very fine-grained geographical and temporal information that is not available for books. The corpus spans 150 years and is formed by millions of articles, representing 14% of all British regional outlets of the period. Simple content analysis of this corpus allowed us to detect specific events, like wars, epidemics, coronations, or conclaves, with high accuracy, whereas the use of more refined techniques from artificial intelligence enabled us to move beyond counting words by detecting references to named entities. These techniques allowed us to observe both a systematic underrepresentation and a steady increase of women in the news during the 20th century and the change of geographic focus for various concepts. We also estimate the dates when electricity overtook steam and trains overtook horses as a means of transportation, both around the year 1900, along with observing other cultural transitions. We believe that these data-driven approaches can complement the traditional method of close reading in detecting trends of continuity and change in historical corpora.

TOO SICK TO START: ENTREPRENEUR'S HEALTH AND BUSINESS ENTRY IN TOWNSHIPS AROUND DURBAN, SOUTH AFRICA.

Chao, Li-Wei; Szrek, Helena; Pereira, Nuno Sousa; Pauly, Mark V

2010-01-01

Unlike large firms with management teams, small businesses are usually run by one key person, the owner-entrepreneur, who bears almost all of the risks and makes almost all of the decisions related to the business. Because the owner-entrepreneur also embodies most of the firm-specific knowledge capital, health of the owner-entrepreneur is an important factor in the production process. Following a cohort of respondents in townships around Durban, South Africa, over a three-year period, we examined the relationship between an individual's physical health and the decision to start a business. Our results suggest that respondents who were recent business entrants were in better health than respondents who did not start new businesses. Moreover, respondents without a business at the beginning of the study who later opened businesses during the three-year study interval were significantly more likely to have better baseline health than those respondents who never started a new business. Hence, good health among entrepreneurs seems to be an important prerequisite to small business entry.

Design study of an advanced gas generator. [which can be ignited during start-up period of turbine engines

NASA Technical Reports Server (NTRS)

Kim, S.; Trinh, H. P.

1993-01-01

A gas generator which can be ignited reliably during the initial start-up period and offers fairly uniform gas temperature at the exit was studied numerically. Various sizes and shapes of the mixing enhancement devices and their positions were examined to evaluate the uniformity of the exit gas temperature and the change of internal pressure drop incurred by introducing the mixing enhancement devices. By introducing a turbulence ring and a splash plate with an appropriate size and position, it was possible to obtain fairly uniform gas temperature distributions and a maximum gas temperature that is within the design limit temperature of 1600 R at the generator exit. However, with the geometry studied, the pressure drop across the generator was great, approximately 1150 psi, to satisfy the assigned design limit temperature. If the design limit temperature is increased to 1650 R, the pressure drop across the generator could be lowered by as much as 350 psi.

This study investigates the performance of an anaerobic baffled reactor (ABR) during the start-up period of raw young landfill leachate treatment at two chemical oxygen demand (COD) to SO4(2-) ratios of 20 and 4. The reactor was operated at ambient temperature and low organic loading rates (0.52, 0.76 and 1.05 kg COD/m3 per day). During the study, sulfate-reducing bacteria (SRB) activity increased at the lower ratio of COD/SO4(2-) producing higher levels of sulfide and alkalinity. The dissolved sulfide concentration reached an inhibitory level above 250 mg/L, which caused a sharp reduction in the total COD removal efficiency from 77-80% to 32%. Total volatile fatty acid (TVFA) production proceeded at a constant level despite increased organic loading. As the effluent total and organic COD concentrations increased, the inhibitory effect of the inborn sulfide was correlated to the limitation experienced in the hydrolysis/acidogenesis stages, and thus VFA production and organic matter removal.

Objective To compare one-year outcomes of women started on antiretroviral therapy (ART) during pregnancy in the pre-Option B+ era to those in the Option B+ era. Methods A retrospective chart review was performed at three sites in Malawi. Women were included in the ‘pre-Option B+’ cohort if they started ART during pregnancy for a CD4 count < 350 cells/mm3 or WHO 3/4 condition and in the ‘Option B+’ cohort if they started ART during pregnancy regardless of CD4 count or clinical stage. One-year outcomes were compared using Fisher's exact and ANOVA F-tests. Results A higher proportion of women in the pre-Option B+ cohort started ART at WHO stage 3/4 (11.9% versus 1.1%, P < 0.001), switched ART regimens (5.9% versus 0%, P = 0.002), or died in the first year after starting treatment (3.9% versus .5%, P = 0.05). While more women in the Option B+ cohort had poor adherence or defaulted, these differences were not significant. Conclusions At our study sites, the transition to Option B+ has been associated with ART initiation in women with less advanced HIV infection, improved medication tolerability, and lower mortality. Further research is needed to better understand outcomes of Option B+. PMID:25774326

Spurious One-Month and One-Year Periods in Visual Observations of Variable Stars

NASA Astrophysics Data System (ADS)

Percy, J. R.

2015-12-01

Visual observations of variable stars, when time-series analyzed with some algorithms such as DC-DFT in vstar, show spurious periods at or close to one synodic month (29.5306 days), and also at about a year, with an amplitude of typically a few hundredths of a magnitude. The one-year periods have been attributed to the Ceraski effect, which was believed to be a physiological effect of the visual observing process. This paper reports on time-series analysis, using DC-DFT in vstar, of visual observations (and in some cases, V observations) of a large number of stars in the AAVSO International Database, initially to investigate the one-month periods. The results suggest that both the one-month and one-year periods are actually due to aliasing of the stars' very low-frequency variations, though they do not rule out very low-amplitude signals (typically 0.01 to 0.02 magnitude) which may be due to a different process, such as a physiological one. Most or all of these aliasing effects may be avoided by using a different algorithm, which takes explicit account of the window function of the data, and/or by being fully aware of the possible presence of and aliasing by very low-frequency variations.

To review the changes in permanent pacemaker implantation indications, pacing modes and patients' demographics over a 20-year period. We retrospectively retrieved data on patients who underwent first implantation of the pacemaker between 1-1-1991 and 31-12-2010. One thousand and nine (1,009) patients underwent a first pacemaker implantation during that period; 535 were men (53%), their mean age was 74.6±19.5 years; the highest rate of implanted pacemaker was in patients ranging in age from 70-79 years, however there was an increasing number of patients aged over 80 years. The median survival time after initial pacemaker implantation was 8 years. Syncope was the most common symptom (62.5%) and atrioventricular block was the most common electrocardiographic indication (56.4%) leading to pacemaker implantation. There was increased utilization of dual chamber and rate responsive pacemakers over the years. There was no difference regarding mode selection between genders. Pacemaker implantation rates have increased over a 20-year period. Dual chamber replaced most of the single ventricular chamber pacemaker and rate responsive pacemakers became the norm. The data of a small volume center are similar to those reported in pacemaker surveys of high volume pacemaker implantation centers. They confirm adherence to the published guidelines for pacing.

Start-up period investigation of pilot-scale submerged membrane electro-bioreactor (SMEBR) treating raw municipal wastewater.

2014-02-01

Submerged membrane electro-bioreactor (SMEBR) is a new hybrid technology for wastewater treatment employing electrical field and microfiltration in a nutrient-removing activated sludge process. A pilot SMEBR system was located at the wastewater treatment plant in the City of l'Assomption (Quebec, Canada) with the objective of investigating the start-up period performance under variable organic loadings and environmental conditions with respect to effluent quality, membrane fouling, and sludge properties. The pilot SMEBR facility was fed with the raw de-gritted municipal wastewater. At steady state operation, the removal efficiencies of ammonia (as NH3(+)-N), phosphorus (as PO4(3-)-P), and COD were 99%, 99%, and 92%, respectively. No substantial increase in the monitored transmembrane pressure as 0.02kPad(-1) was reported. The time necessary to filter 100mL of the sludge sample has decreased by 78% after treatment whilst the sludge volume index averaged 119mLg(-1). Energy requirements were in the range of 1.1-1.6kWhm(-3) of wastewater. It was concluded that the SMEBR is a very competitive technology when compared to conventional membrane systems as it can enhance treatment performance to an appreciable extent, remove phosphorus and reduce fouling.

2013-01-01

One year after participating in the REDI (Research-based, Developmentally-Informed) intervention or “usual practice” Head Start, the learning and behavioral outcomes of 356 children (17% Hispanic, 25% African American, 54% girls; mean age 4.59 years at initial assessment) were assessed. In addition, their 202 kindergarten classrooms were evaluated on quality of teacher-student interactions, emphasis on reading instruction, and school-level student achievement. Hierarchical linear analyses revealed that the REDI intervention promoted kindergarten phonemic decoding skills, learning engagement, and competent social problem-solving skills, and reduced aggressive-disruptive behavior. Intervention effects on social competence and inattention were moderated by kindergarten context, with effects strongest when children entered schools with low student achievement. Implications are discussed for developmental models of school readiness and early educational programs. PMID:23647355

TOO SICK TO START: ENTREPRENEUR’S HEALTH AND BUSINESS ENTRY IN TOWNSHIPS AROUND DURBAN, SOUTH AFRICA

Unlike large firms with management teams, small businesses are usually run by one key person, the owner-entrepreneur, who bears almost all of the risks and makes almost all of the decisions related to the business. Because the owner-entrepreneur also embodies most of the firm-specific knowledge capital, health of the owner-entrepreneur is an important factor in the production process. Following a cohort of respondents in townships around Durban, South Africa, over a three-year period, we examined the relationship between an individual’s physical health and the decision to start a business. Our results suggest that respondents who were recent business entrants were in better health than respondents who did not start new businesses. Moreover, respondents without a business at the beginning of the study who later opened businesses during the three-year study interval were significantly more likely to have better baseline health than those respondents who never started a new business. Hence, good health among entrepreneurs seems to be an important prerequisite to small business entry. PMID:21603114

This study evaluated the influence of an altitude training (AT) camp on swimming start time and loaded squat jump performance. To accomplish this goal, 13 international swimmers (8 women, 5 men) were allocated to both the control (Sea Level Training, SLT) and experimental conditions (AT, 2320 m above sea level) that were separated by a one year period. All tests (15 m freestyle swimming start and loaded squat jumps with additional loads of 25%, 50%, 75%, and 100% of swimmers’ body weight) were performed before and after a concurrent 3-week strength and endurance training program prescribed by the national coach. Following the SLT camp, significant impairments in swimming start times to 10 (+3.1%) and 15 m (+4.0%) were observed (P < 0.05), whereas no significant changes for the same distances were detected following the AT camp (-0.89%; P > 0.05). Trivial changes in peak velocity were obtained during the loaded squat jump after both training periods (effect sizes: < 0.20). Based on these results we can conclude that a traditional training high—living high strategy concurrent training of 3 weeks does not adversely affect swimming start time and loaded squat jump performance in high level swimmers, but further studies are necessary to assess the effectiveness of power-oriented resistance training in the development of explosive actions.

Over 60% of all patients with dura mater graft-associated Creutzfeldt-Jakob disease (dCJD) have been diagnosed in Japan. The incubation period has ranged from 1 to 30 years and the age at onset from 15 to 80 years. Here, we report a 77-year-old male Japanese autopsied dCJD case with the longest incubation period so far in Japan. He received a cadaveric dural graft at the right cranial convexity following a craniotomy for meningioma at the age of 46. At 30 years post-dural graft placement, disorientation was observed as an initial symptom of dCJD. He rapidly began to present with inconsistent speech, cognitive impairment and tremor of the left upper extremity. Occasional myoclonic jerks were predominantly observed on the left side. Brain MRI presented hyperintense signals on diffusion-weighted and T2-weighted images, at the right cerebral cortex. The most hyperintense lesion was located at the right parietal lobe, where the dura mater graft had been transplanted. Single-photon emission CT scan showed markedly decreased cerebral blood flow at the right parietal lobe. EEG revealed diffuse and slow activities with periodic sharp-wave complex discharges seen in the right parietal, temporal and occipital lobes. He died of pneumonia 9 months after onset. Brain pathology revealed non-plaque-type dCJD. Laterality of neuropathological changes, including spongiform change, neuronal loss, gliosis or PrP deposits, was not evident. Western blot analysis showed type 1 PrP CJD . Alzheimer-type pathology and PSP-like pathology were also observed. © 2016 Japanese Society of Neuropathology.

Following the example of many Western countries, where a "minimum volume rule" policy has been adopted as a quality parameter for complex surgical procedures, the Italian National Transplant Centre set the minimum number of kidney transplantation procedures/y at 30/center. The number of procedures performed in a single center over a large period may be treated as a time series to evaluate trends, seasonal cycles, and nonsystematic fluctuations. Between January 1, 1983, and December 31, 2007, we performed 1376 procedures in adult or pediatric recipients from living or cadaveric donors. The greatest numbers of cases/y were performed in 1998 (n = 86) followed by 2004 (n = 82), 1996 (n = 75), and 2003 (n = 73). A time series analysis performed using R Statistical Software (Foundation for Statistical Computing, Vienna, Austria), a free software environment for statistical computing and graphics, showed a whole incremental trend after exponential smoothing as well as after seasonal decomposition. However, starting from 2005, we observed a decreased trend in the series. The number of kidney transplants expected to be performed for 2008 by using the Holt-Winters exponential smoothing applied to the period 1983 to 2007 suggested 58 procedures, while in that year there were 52. The time series approach may be helpful to establish a minimum volume/y at a single-center level. Copyright (c) 2010 Elsevier Inc. All rights reserved.

2016-01-01

Introduction: Acta Informatica Medica is official journal of the Academy for Medical Sciences of Bosnia and Herzegovina (from 2014 Acta Inform Med is published bimonthly). Aim: To evaluate journal “Acta Informatica Medica” in 2015 and compare findings to previous years. Material and methods: The study has retrospective and descriptive character, and included the period 2008-2015 (included 36 issues of journal). Results: A total of 83 (average 13,8 articles per journal) articles were published in Acta Informatica Medica during 2015. Analyzing the type of articles, original articles are present in majority during 2015 (68,6%) (by analyzing last eight years, 310 (67,3%) were original). During 2015, 27,7% of articles were related to the applied of Health informatics in field of clinical medicine, 63,8% preclinical medicine and 8,5% to public health. Collaboration rate in 2015 was 0,84. Most often the time required for decision on acceptance of article in 2015 is between 50 and 60 days. Articles came from 16 countries. According to scimagojr.com for 2014, Acta Informatica Medica has SCImago Journal Rank 0,166, while Cites / Doc. (2 years) parameter (widely used as impact index) is 0,70. According to GoogleScholar, h5 index is 11 and h5 median is 19. We analyzed the Acta Informatica Medica by “Publish or Perish” software - H index was 14, g index was 19 and e-index was 10.39. Conclusion: Year after year the highest number of original articles are published. Although the period of revision of articles is acceptable, the period up to two months is certainly not long, the goal is to reduce this period. Although the magazine in mentioned field found its place, although it is indexed in numerous bases, including: PubMed, PubMed Central, SCOPUS, EMBASE, EBSCO, etc. The main goal for next year is that the magazine becomes part of the Web of Science. Imperative is further internationalization of the magazine. PMID:27147796

The economic and ecological costs of wildfire in the United States have risen substantially in recent decades. Although climate change has likely enabled a portion of the increase in wildfire activity, the direct role of people in increasing wildfire activity has been largely overlooked. We evaluate over 1.5 million government records of wildfires that had to be extinguished or managed by state or federal agencies from 1992 to 2012, and examined geographic and seasonal extents of human-ignited wildfires relative to lightning-ignited wildfires. Humans have vastly expanded the spatial and seasonal "fire niche" in the coterminous United States, accounting for 84% of all wildfires and 44% of total area burned. During the 21-y time period, the human-caused fire season was three times longer than the lightning-caused fire season and added an average of 40,000 wildfires per year across the United States. Human-started wildfires disproportionally occurred where fuel moisture was higher than lightning-started fires, thereby helping expand the geographic and seasonal niche of wildfire. Human-started wildfires were dominant (>80% of ignitions) in over 5.1 million km 2 , the vast majority of the United States, whereas lightning-started fires were dominant in only 0.7 million km 2 , primarily in sparsely populated areas of the mountainous western United States. Ignitions caused by human activities are a substantial driver of overall fire risk to ecosystems and economies. Actions to raise awareness and increase management in regions prone to human-started wildfires should be a focus of United States policy to reduce fire risk and associated hazards.

Wind Magnetic Clouds for the Period 2013 - 2015: Model Fitting, Types, Associated Shock Waves, and Comparisons to Other Periods

We give the results of parameter fitting of the magnetic clouds (MCs) observed by the Wind spacecraft for the three-year period 2013 to the end of 2015 (called the "Present" period) using the MC model of Lepping, Jones, and Burlaga ( J. Geophys. Res. 95, 11957, 1990). The Present period is almost coincident with the solar maximum of the sunspot number, which has a broad peak starting in about 2012 and extending to almost 2015. There were 49 MCs identified in the Present period. The modeling gives MC quantities such as size, axial attitude, field handedness, axial magnetic-field strength, center time, and closest-approach vector. Derived quantities are also estimated, such as axial magnetic flux, axial current density, and total axial current. Quality estimates are assigned representing excellent, fair/good, and poor. We provide error estimates on the specific fit parameters for the individual MCs, where the poor cases are excluded. Model-fitting results that are based on the Present period are compared to the results of the full Wind mission from 1995 to the end of 2015 (Long-term period), and compared to the results of two other recent studies that encompassed the periods 2007 - 2009 and 2010 - 2012, inclusive. We see that during the Present period, the MCs are, on average, slightly slower, slightly weaker in axial magnetic field (by 8.7%), and larger in diameter (by 6.5%) than those in the Long-term period. However, in most respects, the MCs in the Present period are significantly closer in characteristics to those of the Long-term period than to those of the two recent three-year periods. However, the rate of occurrence of MCs for the Long-term period is 10.3 year^{-1}, whereas this rate for the Present period is 16.3 year^{-1}, similar to that of the period 2010 - 2012. Hence, the MC occurrence rate has increased appreciably in the last six years. MC Type (N-S, S-N, All N, All S, etc.) is assigned to each MC; there is an inordinately large percentage of All S

On-board generation of a highly volatile starting fuel to reduce automobile cold-start emissions.

PubMed

Ashford, Marcus D; Matthews, Ronald D

2006-09-15

The on-board distillation system (OBDS) was developed to extract, from gasoline, a high-volatility fuel for exclusive use during the starting and warm-up periods. The use of OBDS distillate fuel results in much improved mixture preparation, allowing combinations of air/fuel ratio and ignition timing that are not possible with gasoline, even with a fully warm engine. The volatility of the distillate is a function of the parent fuel volatility; however, the variability in distillate quality can be diminished via manipulation of the OBDS operating conditions. Thus, it is possible to develop aggressive starting calibrations that are relatively immune to variations in pump gasoline volatility. The key benefits provided bythe OBDS fuel relative to standard gasoline were found to be (1) improved mixture preparation allowing a 70% reduction of cranking fuel requirements, elimination of air-fuel mixture enrichment during the warm-up period, and significant extension of warm-up ignition timing retard; (2) a 57% decrease in catalyst light-off time, (3) emissions reductions over the FTP drive cycle of 81% for regulated hydrocarbons (NMOG); (4) emissions index (NMOG) approaching that of SULEV/PZEV vehicles; and (5) an apparent 1% increase in fuel economy over the FTP drive cycle.

Background Recent studies in multiple sclerosis (MS) showed longer survival times from clinical onset than older hospital-based series. However estimated median time ranges widely, from 24 to 45 years, which makes huge difference for patients as this neurological disease mainly starts around age 20 to 40. Precise and up-to-date reference data about mortality in MS are crucial for patients and neurologists, but unavailable yet in France. Objectives Estimate survival in MS patients and compare mortality with that of the French general population. Methods We conducted a multicenter observational study involving clinical longitudinal data from 30,413 eligible patients, linked to the national deaths register. Inclusion criteria were definite MS diagnosis and clinical onset prior to January, 1st 2009 in order to get a minimum of 1-year disease duration. Results After removing between-center duplicates and applying inclusion criteria, the final population comprised 27,603 MS patients (F/M sex ratio 2.5, mean age at onset 33.0 years, 85.5% relapsing onset). During the follow-up period (mean 15.2 +/- 10.3 years), 1569 deaths (5.7%) were identified; half related to MS. Death rates were significantly higher in men, patients with later clinical onset, and in progressive MS. Overall excess mortality compared with the general population was moderate (Standardized Mortality Ratio 1.48, 95% confidence interval [1.41-1.55]), but increased considerably after 20 years of disease (2.20 [2.10-2.31]). Conclusions This study revealed a moderate decrease in life expectancy in MS patients, and showed that the risk of dying is strongly correlated to disease duration and disability, highlighting the need for early actions that can slow disability progression.

This report describes the third major evaluation of the Program, encompassing program years 2009 to 2011. In this report, this period of time is referred to as the ARRA Period. This is a special period of time for the Program because the American Recovery and Reinvestment Act (ARRA) of 2009 has allocated $5 billion of funding for the Program. In normal program years, WAP s annual appropriation is in the range of $200-250 million, supporting the weatherization of approximately 100,000 homes. With the addition of ARRA funding during these program years, the expectation is that weatherization activity will exceed 300,000more » homes per year. In addition to saving energy and reducing low-income energy bills, expanded WAP funding is expected to stimulate the economy by providing new jobs in the weatherization field and allowing low-income households to spend more money on goods and services by spending less on energy.« less

2001-06-01

Consistent evidence indicates that low socio-economic status (SES) acts as an important stressor and vulnerability factor for children's school learning. However, specific mechanism(s) of this process are still not well understood. This study was a follow-up of the classroom learning behaviour and perceived achievement of low and middle income children after two years at school, who had previously been rated soon after starting school. It examined whether teachers' ratings displayed predictive stability over that period, and whether significant differences evident at age 5 in SES and gender were still operative at age 7. Two samples, of low income (N = 85) and middle income (N = 63) children, were rated following school entry (mean age 5 years 3 months) and rated again after two years at school. The children were rated at both points by their regular classroom teachers using the Learning Behaviours Scale (Stott et al., 1998) with subscales of Distractible, Apprehensive and Uncooperative, together with ratings of academic achievement and their personal perception of each child. SES was found to be a very limited predictor for the learning behaviour subscale ratings and for teachers' personal perceptions at both ages 5 and 7. SES did significantly predict expected Academic Achievement at age 5, but this effect disappeared completely by age 7. Conversely, within the two defined groups, Low Income boys were found to display significantly poorer learning behaviours at age 5, especially in terms of distractible behaviour, compared with Middle Income boys and with girls generally. This pattern was maintained over the next two years of their schooling. The effect of SES was thus demonstrated more powerfully in between-group differences than by means of regression. The findings emphasised the persistence of teachers' initial negative impressions about distractible 'hard to manage' boys from low SES families. The outcomes of this study suggest that low SES boys commenced

Abstract Background Clinical epidemiology data for young adults on renal replacement therapy (RRT) are lacking. While mostly transplanted, they have an increased risk of graft loss during young adulthood. Methods We combined the UK Renal Registry paediatric and adult databases to describe patient characteristics, transplantation and survival for young adults. We grouped patients 11–30 years of age starting RRT from 1999 to 2008 by age band and examined their course during 5 years of follow-up. Results The cohort (n = 3370) was 58% male, 79% white and 29% had glomerulonephritis. Half (52%) started RRT on haemodialysis (HD). Most (78%) were transplanted (18% pre-emptive, 61% as second modality); 11% were not listed for transplant. Transplant timing varied by age group. The deceased:living donor kidney transplant ratio was 2:1 for 11–<16 year olds and 1:1 otherwise. Median deceased donor transplant waiting times ranged from 6 months if <16 years of age to 17 months if ≥21 years. Overall 8% died, with being on dialysis and not transplant listed versus transplanted {hazard ratio [HR] 16.6 [95% confidence interval (CI) 10.8–25.4], P < 0.0001} and diabetes versus glomerulonephritis [HR 4.03 (95% CI 2.71–6.01), P < 0.0001] increasing mortality risk. Conclusions This study highlights the frequent use of HD and the importance of transplant listing and diabetes for young adults. More than half the young adults in our cohort started renal replacement therapy on HD. One in 10 young adults were not listed for transplant by 5 years and were ∼20 times more likely to die than those who were transplanted. Diabetes as a primary renal disease was common among young adults and associated with increased mortality. Overall, almost 1 in 10 young adults had died by 5 years from the start of RRT.

While many studies have shown the benefits of later school starts, including better student attendance, higher test scores, and improved sleep duration, few have used starting times later than 9:00 a.m. Here we report on the implementation and impact of a 10 a.m. school start time for 13 to 16-year-old students. A 4-year observational study using a before-after-before (A-B-A) design was carried out in an English state-funded high school. School start times were changed from 8:50 a.m. in study year 0, to 10 a.m. in years 1-2, and then back to 8:50 a.m. in year 3. Measures of student health (absence due to illness) and academic performance (national examination results) were used for all students. Implementing a 10 a.m. start saw a decrease in student illness after 2 years of over 50% ( p < 0.0005 and effect size: Cohen's d = 1.07), and reverting to an 8:50 a.m. start reversed this improvement, leading to an increase of 30% in student illness ( p < 0.0005 and Cohen's d = 0.47). The 10:00 a.m. start was associated with a 12% increase in the value-added number of students making good academic progress (in standard national examinations) that was significant (<0.0005) and equivalent to 20% of the national benchmark. These results show that changing to a 10:00 a.m. high school start time can greatly reduce illness and improve academic performance. Implementing school start times later than 8:30 a.m., which may address the circadian delay in adolescents' sleep rhythms more effectively for evening chronotypes, appears to have few costs and substantial benefits.

Venture capitalists pour $1 billion a year into health care--and that investment may be the most overlooked indicator of new business opportunities. Signs show that companies focused on consolidation and cost-cutting are off the A list for risk capital. Instead, venture capitalists are targeting start-ups that save money on the front lines by truly managing care.

Immunisation is an important part of childcare practice. It is one of the most beneficial and cost effective measures for the prevention of diseases. From the previous retrospective studies, it was evident that smallpox has been completely eradicated throughout now-a-days with the wholehearted and sincere efforts of healthcare providers by applying efficient and safe vaccine against smallpox, same is true also to polio which is now close to worldwide eradication and measles and rubella are no longer endemic in certain parts of the world. Not only has that with the introduction of safer and more efficient newer vaccines, the incidence of most other vaccine preventable disease of childhood also reduced considerably. The aim of the present study is to estimate the incidence and clinical presentation of adverse events following immunisation with universal and newer vaccines for a period of seven years using prospective active surveillance. Children under the age of 7 years were taken for universal and newer scheduled vaccinations given in the Serampore IMA Child Clinic under the supervision of the clinicians maintaining strictly the guidelines of Expanded Programme of Immunisation (Government of India). This study of adverse events following immunisation in the Serampore IMA Child Clinic confirms that the adverse events such as fever (0.37%), pain and swelling at the site of injection (0.32%0, urticarial rash (0.02%), anaphylactic shock (0.003%) are negligible. There were only two reports of anaphylaxis following preschool and infant schedule vaccines, including measles, mumps and rubella (MMR), Haemophilus influenzae type B vaccines and typhoid vaccines in approximately 52,000 infants received over a period of 7 years starting from 1st April, 2005 to 31st March, 2012 and there were no deaths or longterm effects reported during the post follow-up period in the Serampore IMA Child Clinic.

To determine whether temporal changes occurred in the pediatric vs adult inflammatory bowel disease (IBD), both in terms of number and type of yearly published articles. We aimed to evaluate all PubMed-registered articles related to the field of IBD from January 1, 1993 and until December 31, 2011. We searched for articles using the key words "inflammatory bowel disease" or "Crohn's disease" or "ulcerative colitis" or "undetermined colitis", using the age filters of "child" or "adult". We repeated the search according to the total number per year of articles per type of article, for each year of the specified period. We studied randomized controlled trials, clinical trials, case reports, meta-analyses, letters to the editor, reviews, systematic reviews, practice guidelines, and editorials. We identified 44645 articles over the 19 year-period. There were 8687 pediatric-tagged articles vs 19750 adult-tagged articles. Thus 16208 articles were unaccounted and not assigned a "pediatric" or "adult" tag by PubMed. There was an approximately 3-fold significant increase in all articles recorded both in pediatric and adult articles. This significant increase was true for nearly every category of article but the number of clinical trials, meta-analysis, and randomized controlled trials increased proportionally more than the number of "lower quality" articles such as editorials or letters to the editor. Very few guidelines were published every year. There is a yearly linear increase in publications related to IBD. Relatively, there are more and more clinical trials and higher quality articles.

The economic and ecological costs of wildfire in the United States have risen substantially in recent decades. Although climate change has likely enabled a portion of the increase in wildfire activity, the direct role of people in increasing wildfire activity has been largely overlooked. We evaluate over 1.5 million government records of wildfires that had to be extinguished or managed by state or federal agencies from 1992 to 2012, and examined geographic and seasonal extents of human-ignited wildfires relative to lightning-ignited wildfires. Humans have vastly expanded the spatial and seasonal “fire niche” in the coterminous United States, accounting for 84% of all wildfires and 44% of total area burned. During the 21-y time period, the human-caused fire season was three times longer than the lightning-caused fire season and added an average of 40,000 wildfires per year across the United States. Human-started wildfires disproportionally occurred where fuel moisture was higher than lightning-started fires, thereby helping expand the geographic and seasonal niche of wildfire. Human-started wildfires were dominant (>80% of ignitions) in over 5.1 million km2, the vast majority of the United States, whereas lightning-started fires were dominant in only 0.7 million km2, primarily in sparsely populated areas of the mountainous western United States. Ignitions caused by human activities are a substantial driver of overall fire risk to ecosystems and economies. Actions to raise awareness and increase management in regions prone to human-started wildfires should be a focus of United States policy to reduce fire risk and associated hazards. PMID:28242690

The lag which occurs between the start of NASA-sponsored research and the development of new technology is addressed. A possible common gestation period is examined. The lags vary from one to zero years. The observed lag as it relates to patent applications is shorter than the lag as it relates to invention disclosures. The sequential hypothesis testing showed that invention disclosures correlated better to the measures of research effort used then did patent applications.

Although adolescents generally get less than the recommended 9 hours of sleep per night, research and effort to delay school start times have generally focused on high schools. This study assesses the relation between school start times and sleep in middle school students while accounting for potentially confounding demographic variables. Seventh and eighth grade students attending 8 late starting schools (∼8:00 am, n = 630) and 3 early starting schools (∼7:23 am, n = 343) from a diverse suburban school district completed online surveys about their sleep behaviors. Doubly robust inverse probability of treatment weighted regression estimates of the effects of later school start time on student bedtimes, sleep duration, and daytime sleepiness were generated. Attending a school starting 37 minutes later was associated with an average of 17 additional minutes of sleep per weeknight, despite an average bedtime 15 minutes later. Students attending late starting schools were less sleepy than their counterparts in early starting schools, and more likely to be wide awake. Later school start times were significantly associated with improved sleep outcomes for early adolescents, providing support for the movement to delay school start times for middle schools. © 2018, American School Health Association.

Data from the Head Start Impact Study (N=3,185, age = 3–4 years) were used to determine whether one year of Head Start differentially benefited children from homes with high, middle, and low levels of parental preacademic stimulation on three academic outcome domains – early math, early literacy, and receptive vocabulary. Results from residualized growth models showed positive impacts of random assignment to Head Start on all three outcomes, and positive associations between parental preacademic stimulation and academic performance. Two moderated effects were also found. Head Start boosted early math skills the most for children receiving low parental preacademic stimulation. Effects of Head Start on early literacy skills were largest for children receiving moderate levels of parental preacademic stimulation. Implications for Head Start are discussed. PMID:24597729

Healthy Start is a 3-year demonstration and education research project designed to evaluate the effectiveness of a multidimensional cardiovascular (CV) risk reduction intervention in preschool centers over a 3-year period of time. Two primary interventions are employed. The first is the preschool food service intervention program designed to reduce the total fat in preschool meals and snacks to less than 30% of calories and reduce the saturated fat to less than 10% of calories. The second major intervention is a comprehensive preschool health education curriculum, focused heavily on nutrition. Effectiveness of the intervention will be determined through evaluation of changes in dietary intake of preschool children at school meals and snacks, especially with respect to intake of total and saturated fat. Evaluation of the education component will include assessment of program implementation by teachers, assessment of changes in nutrition knowledge by preschool children, and assessment of changes in home meals that children consume (total and saturated fat content). Blood cholesterol will be evaluated semiannually to evaluate changes that may be due to modification of dietary intake. Growth and body fatness will also be assessed. While substantial efforts have targeted CV risk reduction and health education for elementary school children, similar efforts aimed at preschool children have been lacking. The rationale for beginning CV risk reduction programs for preschool children is based upon the premise that risk factors for heart disease are prevalent by 3 years of age and tend to track over time, most commonly hypercholesterolemia and obesity, both related to nutrition. Since the behavioral antecedents for nutritional risk factors begin to be established very early in life, it is important to develop and evaluate new educational initiatives such as Healthy Start, aimed at the primary prevention of cardiovascular risk factors in preschool children.

Trends in U.S., Past-Year Marijuana Use from 1985–2009; An Age-Period-Cohort Analysis

PubMed Central

Miech, Richard; Koester, Stephen

2014-01-01

Background We present a formal age-period-cohort analysis to examine if the recent increase in past-year marijuana use among the young is specific to the younger generation or if, instead, it is part of a general increase present across cohorts of all ages. This is the first age-period-cohort analysis of past-year marijuana use that includes adult trends from 2001–09. Methods Data come from the National Survey on Drug Use and Health, a series of annual, nationally-representative, cross-sectional surveys of the U.S. civilian, non-institutionalized population. The analysis focuses on the 25 year time span from 1985–2009 and uses the recently developed ‘intrinsic estimator’ algorithm to estimate independent effects of age, period, and cohort. Results The recent increase in past-year marijuana use is not unique to the youngest birth cohorts. An independent, positive influence of cohort membership on past-year marijuana use, net of historical period and age effects, is smaller for today’s youngest cohorts than it was for the cohorts that came immediately before, and, in fact, is at its lowest level in three decades. The recent increase in marijuana use among the young is more consistent with a historical period effect that has acted across all cohorts. Period and cohort trends differ substantially for Hispanics. Conclusions The major forces that drive trends in past-year marijuana use are moving away from cohort-specific factors and toward broad-based influences that affect cohorts of all ages. Strategic public health and policy efforts aimed at countering the recent increase in past-year marijuana use should do the same. PMID:22361212

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

Seyam, Mohammed; Othman, Faridah

2015-07-01

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

Flight Period of Mountain Pine Beetle (Coleoptera: Curculionidae) in its Recently Expanded Range.

PubMed

Bleiker, K P; Van Hezewijk, B H

2016-12-01

The ability to predict key phenological events, such as the timing of flight periods, is useful for the monitoring and management of insect pests. We used empirical data to describe the flight period of mountain pine beetle, Dendroctonus ponderosae Hopkins, in its recently expanded range east of the Rocky Mountains in Canada and developed a degree-day model based on the number of trapped beetles. Data were collected over four degrees of latitude and six years. The main flight period, when the middle 70% of the total number of beetles were caught, started during the second or third week of July, lasted 26 d, and peaked within 2 wk of starting. The best model accounted for 89% of the variation in the data. Mountain pine beetle's flight tended to start later and be more contracted at higher latitudes. The synchrony of mountain pine beetle's flight period in the expanded range appears to be comparable to the limited reports from the historic range, although it may start earlier. This suggests that conditions in the new range are suitable for a coordinated dispersal flight, which is critical for the beetle's strategy of overwhelming tree defenses by attacking en masse. Forest managers can use the model to support operational decisions, e.g., when to impose hauling restrictions to reduce the risk of spread through the transport of infested material, or the time frame for control programs. Understanding the flight period may also improve our ability to assess the response of mountain pine beetle to novel and changing climates in the future. © The Authors 2016.

2005-12-01

The START Collaboratory is a three-year, NSF-funded project to create a Web-based national astronomy research collaboratory for high school students that will bring authentic scientific research to classrooms across the country. The project brings together the resources and experience of Hands-On Universe at the University of California at Berkeley, the Sloan Digital Sky Survey / National Virtual Observatory at Johns Hopkins University and the Northwestern University Collaboratory Project. START Collaboratory documents enable students to create, share and discuss Web-based astronomy research notebooks and research reports. These documents include seamless access to gigabytes of searchable data from the SDSS and the NVO. The START Collaboratory also supports observation requests to a "Telescope Request Broker" that automatically coordinates access to telescopes around the world, and a Web Visualization Tool for visualization and measurement of FITS files from professional observatories or user observations. The project has developed a set of research scenarios that use real astronomical problems to introduce students to the resources and tools available through the START Collaboratory. These scenarios also introduce a model for network-based collaboration that engages students, teachers and professional scientists. Great attention has been paid to ensuring that the research scenarios result in accurate and authentic research products that are of real interest to working astronomers. With the START Collaboratory, students will study science by doing science, generating useful scientific results just as professional astronomers do. As the third and last year of the project finalizes integrating tools and resources, an NSF-funded two-year CI-TEAM project with the Adler Planetarium will begin to create a professional development program for high school teachers interested in learning how to use the START Collaboratory to engage their students in astrophysical research

Periodic Analysis Between Solar Variability and the Earth's Temperature From Centuries to Ten Thousand Years

NASA Astrophysics Data System (ADS)

Zhao, X.; Feng, X. S.

2014-12-01

The global warming is one of the hottest topics for both scientists and the public at present. Strong evidences have shown that the global warming is related to the man-made increasing greenhouse gas levels. Besides the artificial factors, natural forces also contribute to the Earth's climate change. Among them, solar activity is an important ingredient of the natural driving forces of the Earth's climate. In this study, two data sets are adopted to investigate the periodicities of both solar activity and the variation of the Earth temperature as well as their correlations based on the wavelet analysis and cross correlation method. The first one is a directly measured data set covering centuries, while the second one is the reconstructed data during the past 11,000 years. The obtained results demonstrate that solar activity and the Earth's temperature have significant resonance cycles, and the Earth's temperature has periodic variations similar to those of solar activity. For centuries, these common periodicities include the 22-year cycle and the 50-year cycle. While for 11,000 years, they are the 200-year, 500-year, 1000-year, and 2000-year cycles. Correlation analysis reveals that the correlations between solar variability and the Earth's temperature are statistically significant. The correlation coefficient (C.C.) between the 11-year running averaged Total Solar Irradiance (TSI) and the ocean temperature is 0.88 during the past 133 years of global warming. While for 11,000 years, the C.C. between the 500-year running averages of sunspot number (SSN) and the Earth temperature (r=0.51, p=1%) is stronger than that between the temperature and the atmospheric CO2 concentration (r=0.35, p=10%). All these support that solar activity should have non-ignorable effects on the Earth's climate change, especially before the modern industrial time.

Quinn, Robert R.; Garg, Amit X.; Kim, S. Joseph; Wald, Ron; Paterson, J. Michael

2012-01-01

Summary Background and objectives Guidelines promote early fistula creation to avoid central venous catheter use. This practice may lead to fistula creations in patients who never receive dialysis. The objective of this study was to estimate the risk of fistula nonuse with long-term follow-up. Design, setting, participants, & measurements Administrative health data identified 1929 predialysis adults who had their first fistula creation between April of 2002 and March of 2006. Patients were followed for a minimum of 2 years or until they began dialysis, received a kidney transplant, or died. Results The median follow-up times in patients who started dialysis, died without receiving dialysis, and remained in predialysis were 6.1, 11.5, and 38.7 months, respectively. Eighty-one percent of patients initiated dialysis; 9% of patients died without receiving dialysis, and 10% of patients remained predialysis. Forty percent of patients had their first fistula creation 3–12 months before initiating dialysis (the recommended window). Thirty percent were created within 90 days of starting dialysis; 30% were created more than 1 year before starting dialysis, and 10% were created more than 2 years before starting dialysis. Older patients, females, and patients with less comorbidity were not as likely to initiate dialysis after incident fistula creation. Conclusions Most patients who underwent fistula creation before starting dialysis eventually received dialysis with extended follow-up, but the risk was significantly modified by age, sex, and comorbidity. Many patients had fistula creations earlier or later than recommended. PMID:22344512

On High and Low Starting Frequencies of Type II Radio Bursts

We have studied the characteristics of type II radio burst during the period May 1996 to March 2015, for the solar cycle 23 and 24, observed by WIND/WAVES radio instrument. A total of 642 events were recorded by the instrument during the study period. We have divided the events with two starting frequency range (high > 1 MHz; low ≤ 1MHz) as type II1 (i.e., 1-16 MHz) radio burst and type II2 (i.e., 20 KHz - 1020 KHz) radio burst which constitute the DH and km type II radio burst observed by WIND spacecraft, and determined their time and frequency characteristics. The mean drift rate of type II1 and type II2 radio bursts is 29.76 × 10-4 MHz/s and 0.17 × 10-4 MHz/s respectively, which shows that type II1 with high start frequency hase larger drift rate than the type II2 with low starting frequencies. We have also reported that the start frequency and the drift rate of type II1 are in good correlation, with a linear correlation coefficient of 0.58.

Realizing a desired family size: when should couples start?

Until what age can couples wait to start a family without compromising their chances of realizing the desired number of children? The latest female age at which a couple should start trying to become pregnant strongly depends on the importance attached to achieving a desired family size and on whether or not IVF is an acceptable option in case no natural pregnancy occurs. It is well established that the treatment-independent and treatment-dependent chances of pregnancy decline with female age. However, research on the effect of age has focused on the chance of a first pregnancy and not on realizing more than one child. An established computer simulation model of fertility, updated with recent IVF success rates, was used to simulate a cohort of 10 000 couples in order to assess the chances of realizing a one-, two- or three-child family, for different female ages at which the couple starts trying to conceive. The model uses treatment-independent pregnancy chances and pregnancy chances after IVF/ICSI. In order to focus the discussion, we single out three levels of importance that couples could attach to realizing a desired family size: (i) Very important (equated with aiming for at least a 90% success chance). (ii) Important but not at all costs (equated with a 75% success chance) (iii) Good to have children, but a life without children is also fine (equated with a 50% success chance). In order to have a chance of at least 90% to realize a one-child family, couples should start trying to conceive when the female partner is 35 years of age or younger, in case IVF is an acceptable option. For two children, the latest starting age is 31 years, and for three children 28 years. Without IVF, couples should start no later than age 32 years for a one-child family, at 27 years for a two-child family, and at 23 years for three children. When couples accept 75% or lower chances of family completion, they can start 4-11 years later. The results appeared to be robust for

Observations of surface ozone, O3, have been made at the Mace Head Atmospheric Research Station on the North Atlantic Ocean coastline of Ireland over a 30-year period from April 1987 through to April 2017. Using meteorological analyses and a sophisticated Lagrangian dispersion model, the hourly observations have been sorted by air mass histories to separate out the observations for northern hemisphere mid-latitude baseline air masses. Monthly average baseline levels showed a pronounced seasonal cycle with spring maxima and summer minima. Baseline levels have shown an increase during the 1980s and 1990s which has been stronger in the winter and spring and weaker in the summer. The rate of this increase has slowed to the extent that baseline levels have been relatively constant through the 2000s and started to decline in 2010s. The unsorted O3 data has shown different long-term trends from the baseline data because of the influence of European regional NOx and VOC emissions which have reduced wintertime O3 levels below the baseline levels and enhanced summertime O3 levels above them. Episodic peak O3 levels have declined steadily during the study period but 50 ppb 1 h exceedances are likely to continue for the foreseeable future.

Background: Little is known about burden of chronic myeloid leukemia (CML) in India. There is a recent interest to observe incidence and mortality because of advent of new diagnostic and treatment policies for CML. Materials and Methods: We extracted data from the oldest population-based cancer registry of Mumbai for 30 years period from 1976−2005 to observe incidence and mortality rates of CML. We classified the data into four age groups 0–14, 15–29, 30–54 and 55–74 to observe incidence rates in the respective age groups. Results: The age specific rates were highest for the age group of 55–74 years. No significant change in trends of CML was observed for 30 years period. However, there was a significant reduction in incidence rate for recent 15-years period (Estimated average annual percentage change=-3.9). No significant reduction in mortality rate was observed till 2005. Conclusion: The study demonstrates that age-specific rates for CML are highest in age group of 55-74 years, although they are lower compared to western populations. Significant reduction in incidence of CML in recent periods might be because of reduced misclassification of leukemias. The data of CML has to be observed for another decade to witness reduction in mortality because of changes in treatment management. PMID:22174498

Aim To identify factors associated with documented symptomatic and severe hypoglycaemia over 4 years in people with type 2 diabetes starting insulin therapy. Materials and methods CREDIT, a prospective international observational study, collected data over 4 years on people starting any insulin in 314 centres; 2729 and 2271 people had hypoglycaemia data during the last 6 months of years 1 and 4, respectively. Multivariable logistic regression was used to select the characteristics associated with documented symptomatic hypoglycaemia, and the model was tested against severe hypoglycaemia. Results The proportions of participants reporting ≥1 non‐severe event were 18.5% and 16.6% in years 1 and 4; the corresponding proportions of those achieving a glycated haemoglobin (HbA1c) concentration <7.0% (<53 mmol/mol) were 24.6% and 18.3%, and 16.5% and 16.2% of those who did not. For severe hypoglycaemia, the proportions were 3.0% and 4.6% of people reaching target vs 1.5% and 1.1% of those not reaching target. Multivariable analysis showed that, for documented symptomatic hypoglycaemia at both years 1 and 4, baseline lower body mass index and more physical activity were predictors, and lower HbA1c was an explanatory variable in the respective year. Models for documented symptomatic hypoglycaemia predicted severe hypoglycaemia. Insulin regimen was a univariate explanatory variable, and was not retained in the multivariable analysis. Conclusions Hypoglycaemia occurred at significant rates, but was stable over 4 years despite increased insulin doses. The association with insulin regimen and with oral agent use declined over that time. Associated predictors and explanatory variables for documented symptomatic hypoglycaemia conformed to clinical impressions and could be extended to severe hypoglycaemia. Better achieved HbA1c was associated with a higher risk of hypoglycaemia. PMID:29205734

Trends in National Emergency Medicine Conference Didactic Lectures Over a 6-Year Period.

PubMed

Gottlieb, Michael; Riddell, Jeff; Njie, Abdoulie

2017-01-01

National conference didactic lectures have traditionally featured hour-long lecture-based presentations. However, there is evidence that longer lectures can lead to both decreased attention and retention of information. The authors sought to identify trends in lecture duration, lecture types, and number of speakers at four national emergency medicine (EM) conferences over a 6-year period. The authors performed a retrospective analysis of the length, number of speakers, and format of didactic lectures at four different national EM conferences over 6 years. The authors abstracted data from the national academic assemblies for the four largest not-for-profit EM organizations in the United States: American Academy of Emergency Medicine, American College of Emergency Physicians, Council of Emergency Medicine Residency Directors, and Society for Academic Emergency Medicine. There was a significant yearly decrease in the mean lecture lengths for three of the four conferences. There was an increase in the percentage of rapid fire sessions over the preceding 2 years with a corresponding decrease in the percentage of general educational sessions. There was no significant difference in the mean number of speakers per lecture. An analysis of 4210 didactic lecture sessions from the annual meetings of four national EM organizations over a 6-year period showed significant decreases in mean lecture length. These findings can help to guide EM continuing medical education conference planning and research.

Conflict of interest: none declared. Introduction COPD (chronic obstructive pulmonary disease) is characterized by airflow limitation that is not fully reversible. OBJECTIVE: to show the changes of pulmonary function in COPD during the 4 -year evolution of illness. Material and Methods The research was done on patients suffering from COPD treated at the Clinic “Podhrastovi” during 2006 and 2007. The tested parameters were examined from the date of receiving patient with COPD to hospital treatment in 2006 and 2007 and then followed prospectively until 2010 or 2011 (the follow-up period was 4 years). There were total 199 treated patients who were chosen at random and regularly attended the control examinations. The study was conducted on adult patients of both sexes, different age group. In each patient the duration of illness was recorded so is sex, age, data of smoking habits, information about the regularity of taking bronchodilator therapy during remissions of disease, about the treatment of disease exacerbations, results of pulmonary functional tests as follows: FVC (forced vital capacity), FEV1 (forced expiratory volume in one second) and bronchodilator reversibility testing. All these parameters were measured at the beginning and at the end of each hospital treatment on the apparatuses of Clinic “Podhrastovi”. We took in elaboration those data obtained in the beginning of the first hospitalization and at the end of the last hospitalization or at the last control in outpatient department when patient was in stable state. Patients were divided into three groups according to the number of exacerbations per year. Results airflow limitation in COPD is progressive; both FVC and FEV1 shows the statistically significant decrease during follow-up period of 4 years (p values / for both parameters/ =0.05) . But in patients regularly treated in phases of remission and exacerbations of illness the course of illness is slower. The fall of FVC and FEV1 is

Adolescents who do not get enough sleep are more likely to be overweight; not engage in daily physical activity; suffer from depressive symptoms; engage in unhealthy risk behaviors such as drinking, smoking tobacco, and using illicit drugs; and perform poorly in school. However, insufficient sleep is common among high school students, with less than one third of U.S. high school students sleeping at least 8 hours on school nights. In a policy statement published in 2014, the American Academy of Pediatrics (AAP) urged middle and high schools to modify start times as a means to enable students to get adequate sleep and improve their health, safety, academic performance, and quality of life. AAP recommended that "middle and high schools should aim for a starting time of no earlier than 8:30 a.m.". To assess state-specific distributions of public middle and high school start times and establish a pre-recommendation baseline, CDC and the U.S. Department of Education analyzed data from the 2011-12 Schools and Staffing Survey (SASS). Among an estimated 39,700 public middle, high, and combined schools* in the United States, the average start time was 8:03 a.m. Overall, only 17.7% of these public schools started school at 8:30 a.m. or later. The percentage of schools with 8:30 a.m. or later start times varied greatly by state, ranging from 0% in Hawaii, Mississippi, and Wyoming to more than three quarters of schools in Alaska (76.8%) and North Dakota (78.5%). A school system start time policy of 8:30 a.m. or later provides teenage students the opportunity to achieve the 8.5-9.5 hours of sleep recommended by AAP and the 8-10 hours recommended by the National Sleep Foundation.

Neuropsychiatric symptoms are nearly universal in dementia, yet little is known about their longitudinal course in the community. To estimate point and 5-year period prevalence of neuropsychiatric symptoms in an incident sample of 408 dementia participants from the Cache County Study. The Neuropsychiatric Inventory assessed symptoms at baseline and at 1.5 years, 3.0 years, 4.1 years, and 5.3 years. Point prevalence, period prevalence and mean symptom severity at each time point were estimated. Point prevalence for delusions was 18% at baseline and 34-38% during the last three visits; hallucinations, 10% at baseline and 19-24% subsequently; agitation/aggression fluctuated between 13% and 24%; depression 29% at baseline and 41-47% subsequently; apathy increased from 20% at baseline to 51% at 5.3 years; elation never rose above 1%; anxiety 14% at baseline and 24-32% subsequently; disinhibition fluctuated between 2% and 15%; irritability between 17% and 27%; aberrant motor behavior gradually increased from 7% at baseline to 29% at 5.3 years. Point prevalence for any symptom was 56% at baseline and 76-87% subsequently. Five-year period prevalence was greatest for depression (77%), apathy (71%), and anxiety (62%); lowest for elation (6%), and disinhibition (31%). Ninety-seven percent experienced at least one symptom. Symptom severity was consistently highest for apathy. Participants were most likely to develop depression, apathy, or anxiety, and least likely to develop elation or disinhibition. Give converging evidence that syndromal definitions may more accurately capture neuropsychiatric co-morbidity in dementia, future efforts to validate such syndromes are warranted.

Context Pelvic region pressure sores often develop following spinal cord injury. Surgery is often necessary for long standing, large-sized pressure sores not responding to conservative treatment. Authors analyze their results of a 10-year period, and identify factors contributing to the reduction of the recurrence rate. Methods A total of 119 pressure sores were operated on 98 patients in two institutions during a 10-year period (1 January 2003 to 31 December 2012). The encountered perioperative complications are summarized, and the recurrence rate is analyzed with a patient follow-up questionnaire. Results We experienced 15 perioperative complications (12.6%). All complications were fully resolved by conservative treatment. Fifty-eight returned patient replies were processed. The average follow-up time after surgery was 5.2 years. The recurrence rate was 5.47%. Conclusion The strict adherence to surgical indications, full patient compliance, specialized pre- and post-operative patient care, our routinely used preferred surgical method, all contribute to a low post-operative complication rate, long-term flap survival, and an extended recurrence free period.

Background: Common adverse effects of atypical antipsychotic treatments for schizophrenia are weight gain and lipid metabolism abnormality. We aimed to identify the signs of metabolic problems with continuous atypical antipsychotic treatment for schizophrenia over a 2-year period. Methods: The participants were 68 schizophrenic patients (29 males, 39 females; ages 53.4 ± 13.5 years old). Changes in carbohydrate metabolism and changes in physical characteristics were studied over a 2-year period. In addition, functional single nucleotide polymorphisms in the transcriptional regulatory region of the resistin gene were examined. Results: We found no changes in the mental state of the participants over a 2-year period. Patients did show a significant decrease in total cholesterol and hemoglobin A1c levels, although physical changes such as body mass index and abdominal girth, were not observed. The amount of resistin may not be associated with mental states and physical parameters. Conclusions: We could not find physical factors related to metabolic changes of antipsychotics in this 2-year study. However, several psychological factors, such as health-related thoughts and behaviors, should be studied in the future. PMID:26557983

Climate change and its impact on birch pollen quantities and the start of the pollen season an example from Switzerland for the period 1969-2006

As published by the Intergovernmental Panel on Climate Change (IPCC) global warming is a reality and its impact is huge like the increase of extreme weather events, glacier recession, sea level rise and also effects on human health. Among them allergies to airborne pollen might increase or change in pattern due to the invasion of new allergic plants or due to different behavior of plants like earlier flowering. In this study we used the longest Swiss airborne pollen data set to examine the influence of the temperature increase on the time of flowering. In the case of Basel, where pollen data for 38 years are available, it was shown that due to a temperature increase the start of flowering in the case of birch occurred about 15 days earlier. Apart from a shift of the start of the flowering there is also a trend towards higher annual birch pollen quantities and an increase of the highest daily mean pollen concentrations. Due to global warming and because symptoms may appear earlier in the year people suffering from a pollen allergy might face a new unaccustomed situation.

Possible Rivaroxaban Failure during the Postpartum Period.

PubMed

Rudd, Kelly M; Winans, Amanda R McFee; Panneerselvam, Narmadha

2015-11-01

Rivaroxaban, a factor Xa inhibitor, is a direct-acting oral anticoagulant (DOAC) indicated for the treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE), and for reducing the risk of DVT and PE recurrence. To our knowledge, no data are presently available to guide DOAC dosing in the postpartum period when pharmacokinetic and pharmacodynamic changes induced by pregnancy have an impact on drug clearance and increase hypercoagulability for a period of 6-8 weeks after delivery. We describe the case of a 35-year-old postpartum woman who presented to the emergency department with a diagnosis of a new multiple segmental PE 5 days after starting rivaroxaban therapy for a diagnosis of DVT. No precipitating cause, including noncompliance, was identified as a source of thrombosis embolization or extension. The patient was admitted, a heparin infusion was started for the management of PE, and rivaroxaban was discontinued. She was transitioned to enoxaparin 1 mg/kg (90 mg) subcutaneously every 12 hours the next day, bridged to warfarin, and discharged home on the overlapping regimen with close follow-up by the pharmacist-managed outpatient Anticoagulation Management Service. To our knowledge, this is the first case report of potential failure associated with rivaroxaban therapy in the postpartum period, possibly due to pharmacokinetic alterations seen in the postpartum period contributing to decreased drug exposure, yielding reduced anticoagulant efficacy. Clinicians should carefully weigh the risks and benefits of DOAC therapy in postpartum patients or other special populations requiring anticoagulation therapy. This report also highlights the need for further research identifying the impact of pharmacokinetic changes induced by special populations and the need to develop monitoring assays for such clinical situations. © 2015 Pharmacotherapy Publications, Inc.

We aimed to determine the effects of age, period, and birth cohort on cervical cancer mortality rate trends in Japanese women, by age-period-cohort (APC) analysis. Additionally, we analyzed projected mortality rates. We obtained data on the number of cervical cancer deaths in Japanese women from 1975-2011 from the national vital statistics and census population data. A cohort table of mortality rate data was analyzed on the basis of a Bayesian APC model. We also projected the mortality rates for the 2012-2031 period. The period effect was relatively limited, compared with the age and cohort effects. The age effect increased suddenly from 25-29 to 45-49 years of age and gently increased thereafter. An analysis of the cohort effect on mortality rate trends revealed a steep decreasing slope for birth cohorts born from 1908-1940 and a subsequent sudden increase after 1945. The mortality rate projections indicated increasing trends from 40 to 74 years of age until the year 2031. The age effect increased from 25-29 years of age. This could be attributable to the high human papilloma virus (HPV) infection risk and the low cervical cancer screening rate. The cohort effect changed from decreasing to increasing after the early 1940s. This might be attributable to the spread of cervical cancer screening and treatment before 1940 and the high HPV infection risk and reduced cervical cancer screening rate after 1945. The projected mortality rate indicated an increasing trend until the year 2031.

The strange case of Mr. H. Starting dialysis at 90 years of age: clinical choices impact on ethical decisions.

PubMed

Piccoli, Giorgina Barbara; Sofronie, Andreea Corina; Coindre, Jean-Philippe

2017-11-09

Starting dialysis at an advanced age is a clinical challenge and an ethical dilemma. The advantages of starting dialysis at "extreme" ages are questionable as high dialysis-related morbidity induces a reflection on the cost- benefit ratio of this demanding and expensive treatment in a person that has a short life expectancy. Where clinical advantages are doubtful, ethical analysis can help us reach decisions and find adapted solutions. Mr. H is a ninety-year-old patient with end-stage kidney disease that is no longer manageable with conservative care, in spite of optimal nutritional management, good blood pressure control and strict clinical and metabolic evaluations; dialysis is the next step, but its morbidity is challenging. The case is analysed according to principlism (beneficence, non-maleficence, justice and respect for autonomy). In the setting of care, dialysis is available without restriction; therefore the principle of justice only partially applied, in the absence of restraints on health-care expenditure. The final decision on whether or not to start dialysis rested with Mr. H (respect for autonomy). However, his choice depended on the balance between beneficence and non-maleficence. The advantages of dialysis in restoring metabolic equilibrium were clear, and the expected negative effects of dialysis were therefore decisive. Mr. H has a contraindication to peritoneal dialysis (severe arthritis impairing self-performance) and felt performing it with nursing help would be intrusive. Post dialysis fatigue, poor tolerance, hypotension and intrusiveness in daily life of haemodialysis patients are closely linked to the classic thrice-weekly, four-hour schedule. A personalized incremental dialysis approach, starting with one session per week, adapting the timing to the patient's daily life, can limit side effects and "dialysis shock". An individualized approach to complex decisions such as dialysis start can alter the delicate benefit/side-effect balance

We also assessed the extent of knowledge of the Spanish health legislation on tobacco (Ley 28/2005) and its effect on smoking. We administered a questionnaire to representative samples of students from the 1st year of their Psychology course to the 5th year, on four occasions. In the academic year 1996-1997 (N = 835), 34% of the sample claimed to be daily smokers; in 1999-2000 (N = 842), the figure was 35.2%; in 2003-2004 (N = 835) it was 31.9%; and in 2006-2007 (N = 688), it was 22.8%. Moreover, in the last assessment, 97.1% of the sample reported being aware of the legislation (Ley 28/2005) and 41.9% of the smokers claimed that it had some degree of influence on their smoking. It can be stated that, although overall current prevalence of smoking is similar to that of 10 years ago, a significant change is observed in the profile of smokers. This change is expressed in lower levels of nicotine dependence and a decrease in the percentage of daily smokers, together with an increase in occasional smokers.

The present study aimed to (1) determine the long-term effectiveness of Home-Start, a preventive parenting program, and (2) test the hypothesis that changes in maternal sense of competence mediate the program’s effects. Participants were 124 mothers (n = 66 intervention, n = 58 comparison). Four assessments took place during a 1-year period. Latent growth modeling showed that Home-Start enhanced growth in maternal sense of competence and supportive parenting, and led to a decrease in the use of inept discipline. Results of mediational and cross-lagged analyses were consistent with the hypothesized model: Participation in Home-Start was related to the changes in maternal sense of competence, which in turn predicted changes in parenting. The results affirm the importance of directly targeting parental sense of competence in the context of prevention work with parents. PMID:20101464

Objective: To analyze and compare the changes in physical fitness according to the nutritional status and gender of schoolchildren during a period of 30 years (1980-2010). Methods: Four cross-sectional evaluations were performed every 10 years in a period of 30 years from 1978 to 1980 (baseline), 1988-1990 (10 years), 1998-2000 (20 years) and 2008-2010 (30 years). The sample consisted of 1291 schoolchildren (188 in baseline, 307 in 10 years; 375 in 20 years; 421 in 30 years) of 10 and 11 years old. The variables assessed were: body weight (kg), height (cm), upper limb strength (ULS; kg), lower limb strength (LLS; cm), agility (seconds) and velocity (seconds). Schoolchildren were classified as normal weight and overweight according to World Health Organization reference of body mass index for age and gender. Comparisons among periods applied ANOVA followed by Bonferroni test, with a significance level set at of p<0.01. Variation between baseline and 30 years was assessed by the percentage delta. Seven different percentile values were presented for each variable. Results: In eutrophic boys and girls, mean values of ULS (−16.7%; −3.2%), agility (−1.5%; −1.6%) decreased significantly after 30 years (p<0.001). In the overweight boys and girls, only the average ULS (−15.5%; −12.5%) decreased significantly over time (p<0.001). After 30 years, the ULS percentile changed in boys. Conclusions: The decline in physical fitness was greater in schoolchildren with normal weight than in those with overweight. PMID:26298653

Aim MULTIPRAC was designed to provide insights into the use and outcomes associated with prehospital initiation of antiplatelet therapy with either prasugrel or clopidogrel in the context of primary percutaneous coronary intervention. After a previous report on efficacy and safety outcomes during hospitalization, we report here the 1-year follow-up data, including cardiovascular (CV) mortality. Methods and results MULTIPRAC is a multinational, prospective registry of patients with ST-elevation myocardial infarction (STEMI) from 25 hospitals in nine countries, all of which had an established practice of prehospital start of dual antiplatelet therapy in place. The key outcome was CV death at 1 year. Among 2,036 patients followed-up through 1 year, 49 died (2.4%), 10 during the initial hospitalization and 39 within 1 year after hospital discharge. The primary analysis was based on the P2Y12-inhibitor, used from prehospital loading dose through hospital discharge. Prasugrel (n=824) was more commonly used than clopidogrel (n=425). The observed 1-year rates for CV death were 0.5% with prasugrel and 2.6% with clopidogrel. After adjustment for differences in baseline characteristics, treatment with prasugrel was associated with a significantly lower risk of CV death than treatment with clopidogrel (odds ratio 0.248; 95% confidence interval 0.06–0.89). Conclusion In STEMI patients from routine practice undergoing primary angioplasty, who were able to start oral antiplatelet therapy prehospital, treatment with prasugrel as compared to clopidogrel was associated with a lower risk of CV death at 1-year follow-up.

There is scant information available regarding the distribution of periodontal bacterial species in children and adolescents over an extended period. The purpose of this study was to compare bacterial profiles in the same individuals over a period of 7 years. Twenty-six children and adolescents from whom dental plaque and saliva specimens were obtained during both the first (1999-2000) and second (2006-2007) periods, were analyzed. Bacterial DNA was extracted from each specimen and the presence of 10 periodontal bacterial species was determined using a PCR method, with a focus on the red complex species of Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia. Subjects with red complex species in saliva specimens obtained during the second collection possessed a significantly higher number of total bacterial species than those without. The detection rate of the red complex species in the second collection period samples was significantly greater in subjects who had two or more species detected in samples taken during the first collection compared with the other subjects. Subjects possessing red complex species may be at possible risk for infection with a high number of periodontal bacterial species during adolescent and younger adult years.

Timing and duration of autumn leaf development in Sweden, a 4-year citizen science study

Phenology monitoring has traditionally focused on the start of phenological phases and the start of the growing season, especially when it comes to species-specific observations on the ground. The patterns of and the mechanisms behind the end of particular phases and the growing season itself are less studied and poorly understood. With a changing climate, the need to understand and predict effects on the length as well as on the end of phenological phases increase in importance, e.g. in relation to estimations of carbon budgets and validation of remote sensing data. Furthermore, different species may be affected in different ways by changing conditions. In this 4-year-study, tens of thousands of pupils in ages from 6 to 19 years old were involved in observing autumn leaf development of common deciduous tree species. Their observations were made near schools all over Sweden (55-68°N). Observations were made weekly between late August and early November and followed an image-based observation protocol, classifying autumn leaf development into five levels, from a summer-green (level 0) to a 100% autumn-colored (level 4) canopy. As expected, there was a general (negative) correlation between latitude and the start of leaf senescence (level 2; 1/3 autumn-colored canopy), but the correlation differed largely among years and between species. There was a week correlation between latitude and duration of the leaf senescence period, defined as the period between 1/3 (level 2) and 100% (level 4) of autumn-colored canopy. A delayed onset of the leaf senescence affected the duration of the leaf senescence period more strongly; One (1) day later start was correlated with a 5-day shorter period. Different species had different length of their senescence period, with oak (mainly Quercus robur) and birches (Betula pendula and B. pubescence) having on average a 50% longer period than trembling aspen (Populus tremula) and Norway maple (Acer platanoides).

Time-related changes and comparisons for mid-upper arm circumference (MUAC), triceps skinfold thickness (TSF), arm fat area (AFA) are lacking for Turkish children and adolescents. To determine the arm anthropometry indices (MUAC, TSF, AFA) in children and adolescents and to also assess the changes in these indices over a 3-year time period. The data of the Anthropometry of Turkish Children Aged 0-6 Years (ATCA-06) study and the Second Study of Determination of the Anthropometric Measurements of Turkish Children and Adolescents (DAMTCA-II) were used to calculate the arm anthropometry percentiles in a total group of 6982 children and adolescents aged 28 days to 17 years. The 3rd-97th percentiles were computed by the LMS method. In girls, 50th percentile MUAC values linearly increased with age. In boys, 50th percentile TSF values linearly increased until 10 years of age and decreased after age 11 years, while in girls, TSF values increased linearly with age. 50th percentile values for AFA showed a linear increase in both genders with age. Significant differences were found between the 5th, 50th and 95th percentile values for MUAC and AFA obtained in the two studies (DAMTCA-II and DAMTCA-I) in both boys and girls. The prominent finding was the significant and alarming increase in arm anthropometry indices in both genders within as short period of time as three years.

OBJECTIVES: To examine the variation of symptoms from the neck, shoulders, and back over a three year period among female nursing personnel and the relation between job strain and musculoskeletal symptoms. METHODS: At a county hospital the female nursing personnel answered a questionnaire at baseline and then once a year over a period of three years. There were 565, 553, 562, and 419 subjects who answered the questionnaire at the first, second, third, and fourth survey, respectively. Of the study group, 285 nursing personnel answered the questionnaire on four occasions. Ongoing symptoms of the neck, shoulders, and back were assessed by means of a 10 point (0-9) scale with the verbal end points "no symptoms" and "very intense symptoms." Cases were defined as nursing personnel reporting ongoing symptoms, score > 6, from at least one of the body regions. For assessments of job strain, a Swedish version of Karasek and Theorell's model was used. RESULTS: Of the 285 subjects, 13% were defined as cases at all four assessments, and 46% varied between cases and not cases during the study period. In the repeated cross sectional surveys the estimated rate ratio (RR) for being a case was between 1.1 and 1.5 when comparing the group with job strain and the group without job strain. For the combination of job strain and perceived high physical exertion the estimated RR was between 1.5 and 2.1. When the potential risk factors were assessed one, two, or three years before the assessment of symptoms the estimated RR for becoming a case was between 1.4 and 2.2 when comparing the group with job strain and the group without job strain. CONCLUSION: Almost half of the healthcare workers varied between being a case and not, over a three year period. The analysis indicated that job strain is a risk factor for musculoskeletal symptoms and that the risk is higher when it is combined with perceived high physical exertion. PMID:9423583

A number of insulin regimens are used in type 2 diabetes. This analysis aims to better understand the evolution of insulin therapy in different regions of Europe. Data from people starting any insulin were collected in eastern Europe (EEur: Croatia, Russia, Ukraine), northern Europe (NEur: Finland, Germany, UK) and southern Europe (SEur: France, Italy, Portugal, Spain). Retrospective data on starting insulin and prospective follow-up data were extracted from clinical records. At 4years, 1699 (76.0%) of 2236 eligible people had data. EEur participants were mostly female, younger and had shorter diabetes duration on starting insulin, yet had highest baseline HbA1c and more micro-/macrovascular disease. A majority (60%-64%) in all regions started on basal insulin alone, declining to 30%-38% at 4years, with most switching to basal+mealtime insulin regimen (24%-40%). Higher baseline (28%) and 4-year use (34%) of premix insulin was observed in NEur. Change in HbA1c (SD) ranged from -1.2 (2.1)% (-13 [23]mmol/mol) in NEur to -2.4 (2.0)% (-26 [22]mmol/mol) in EEur. Weight change ranged from +1.9 (8.3) kg in NEur to +3.2 (7.0) kg in SEur. Overall documented hypoglycemia ranged from 0.3 (1.3) to 1.3 (4.4) events/person/6-months (NEur vs. EEur, respectively) and was stable with time. Severe hypoglycemia rates remained low. When starting insulin, HbA1c and prevalence of complications were higher in EEur. Regional differences exist in choice of insulin regimens in Europe. However, people starting insulin improved and sustained their glycemic control regardless of regional differences or insulin regimens used. Copyright © 2017 The Authors. Published by Elsevier B.V.

2018-02-08

The National Health Service was estimated to be in £2.45 billion deficit in 2015 to 2016. Trauma theatre utilization and efficiency has never been so important as it is estimated to cost £15/minute. Structured questionnaires were given to 23 members of staff at our Trust who are actively involved in the organization or delivery of orthopaedic trauma lists at least once per week. This was used to identify key factors that may improve theatre efficiency. Following focus group evaluation, the location of the preoperative theatre meeting was changed, with all staff involved being required to attend this. Our primary outcome measure was mean theatre start time (time of arrival in the anaesthetic room) during the 1 month immediately preceding the change and the month following the change. Theatre start time was improved on average 24 minutes (1 month premeeting and postmeeting change). This equates to a saving of £360 per day, or £131 040 per year. Changing the trauma meeting location to a venue adjacent to the trauma theatre can improve theatre start times, theatre efficiency, and therefore result in significant cost savings.

Surianarayanan, S.; Suribabu, C. R.; Ramakrishnan, K.

2017-07-01

The dry period agriculture is inevitable both for the farmers for their earning, and for the soil for its fertility by crop-rotation. In tropical countries like INDIA, dry period agriculture becomes difficult because of less (or) no rain fall. Hence a simple water balancing model for irrigation scheduling, using the measure “Volumetric Reliability” is prepared in this paper, with the storage and inflow of a reservoir both for the dry and wet periods. The case-study is done for a reservoir in INDIA with thirty one years of hydrological data(from 1982 to 2012). The objective of this paper is to prepare a simple water balance model taking 10 days periods of demand and supply for ID crop(Irrigated Dry crop, ground nut) with usage of volumetric reliability concept for the periods of deficiency and adoption of less water requirement crops to reduce the water-stress during critical periods of crop growth, and finally arrive at a feasible allocation schedule for the success of agriculture and the yield throughout the year both for wet and dry crops with the available storage on the start of irrigation for a particular year. The reservoir is divided for storages such as full, deficient and critical storages. The starting storage for the dry period from January is used after adequate allocation for wet crops, the quantity for riparian rights and for drinking water, for the sustainability. By the water-balancing, the time-series for thirty one years, it is found that for twenty two years the demand for the ID crops is satisfied with the storage in the reservoir, and in the remaining years of deficient inflows, for three years (1986,1996,2004)the demand is managed by using the safe reliability factor for demand which can nullify the deficit in demand for the whole supply period. But it is genuine to assure that the reduction in the amount of water for each 10 days periods should not exceed the survival limit of the crop. Necessary soil-moisture must be ensured in the crop

Rapid starting methanol reactor system

DOEpatents

Chludzinski, Paul J.; Dantowitz, Philip; McElroy, James F.

1984-01-01

The invention relates to a methanol-to-hydrogen cracking reactor for use with a fuel cell vehicular power plant. The system is particularly designed for rapid start-up of the catalytic methanol cracking reactor after an extended shut-down period, i.e., after the vehicular fuel cell power plant has been inoperative overnight. Rapid system start-up is accomplished by a combination of direct and indirect heating of the cracking catalyst. Initially, liquid methanol is burned with a stoichiometric or slightly lean air mixture in the combustion chamber of the reactor assembly. The hot combustion gas travels down a flue gas chamber in heat exchange relationship with the catalytic cracking chamber transferring heat across the catalyst chamber wall to heat the catalyst indirectly. The combustion gas is then diverted back through the catalyst bed to heat the catalyst pellets directly. When the cracking reactor temperature reaches operating temperature, methanol combustion is stopped and a hot gas valve is switched to route the flue gas overboard, with methanol being fed directly to the catalytic cracking reactor. Thereafter, the burner operates on excess hydrogen from the fuel cells.

A study of start-up characteristics of a potassium heat pipe from the frozen state

NASA Technical Reports Server (NTRS)

Jang, Jong Hoon

1992-01-01

The start up characteristics of a potassium heat pipe were studied both analytically and experimentally. Using the radiation heat transfer mode the heat pipe was tested in a vacuum chamber. The transition temperature calculated for potassium was then compared with the experimental results of the heat pipe with various heat inputs. These results show that the heat pipe was inactive until it reached the transition temperature. In addition, during the start up period, the evaporator experienced dry-out with a heat input smaller than the capillary limit calculated at the steady state. However, when the working fluid at the condensor was completely melted, the evaporation was rewetted without external aid. The start up period was significantly reduced with a large heat input.

Abdominal injuries in a major Scandinavian trauma center – performance assessment over an 8 year period

PubMed Central

2014-01-01

Introduction Damage control surgery and damage control resuscitation have reduced mortality in patients with severe abdominal injuries. The shift towards non-operative management in haemodynamically stable patients suffering blunt abdominal trauma has further contributed to the improved results. However, in many countries, low volume of trauma cases and limited exposure to trauma laparotomies constitute a threat to trauma competence. The aim of this study was to evaluate the institutional patient volume and performance for patients with abdominal injuries over an eight-year period. Methods Data from 955 consecutive trauma patients admitted in Oslo University Hospital Ulleval with abdominal injuries during the eight-year period 2002-2009 were retrospectively explored. A separate analysis was performed on all trauma patients undergoing laparotomy during the same period, whether abdominal injuries were identified or not. Variable life-adjusted display (VLAD) was used in order to describe risk-adjusted survival trends throughout the period and the patients admitted before (Period 1) and after (Period 2) the institution of a formal Trauma Service (2005) were compared. Results There was a steady increase in admitted patients with abdominal injuries, while the number of patients undergoing laparotomy was constant exposing the surgical trauma team leaders to an average of 8 trauma laparotomies per year. No increase in missed injuries or failures of non-operative management was detected. Unadjusted mortality rates decreased from period 1 to period 2 for all patients with abdominal injuries as well as for the patients undergoing laparotomy. However, this apparent decrease was not confirmed as significant in TRISS-based analysis of risk-adjusted mortality. VLAD demonstrated a steady performance throughout the study period. Conclusion Even in a high volume trauma center the exposure to abdominal injuries and trauma laparotomies is limited. Due to increasing NOM, an increasing

Congenital heart disease is a major cause of infant mortality in developed countries. In Spain, there are no publications at national level on mortality due to congenital heart disease. The aim of this study is to analyse mortality in infants with congenital heart disease, lethality of different types of congenital heart disease, and their variation over a ten-year period. A retrospective observational study was performed to evaluate mortality rate of children under one year old with congenital heart disease, using the minimum basic data set, from 2003 to 2012. Mortality rate and relative risk of mortality were estimated by Poisson regression. There were 2,970 (4.58%) infant deaths in a population of 64,831 patients with congenital heart disease, with 73.8% of deaths occurring during first week of life. Infant mortality rate in patients with congenital heart disease was 6.23 per 10,000 live births, and remained constant during the ten-year period of the study, representing 18% of total infant mortality rate in Spain. The congenital heart diseases with highest mortality rates were hypoplastic left heart syndrome (41.4%), interruption of aortic arch (20%), and total anomalous pulmonary drainage (16.8%). Atrial septal defect (1%) and pulmonary stenosis (1.1%) showed the lowest mortality rate. Congenital heart disease was a major cause of infant mortality with no variations during the study period. The proportion of infants who died in our study was similar to other similar countries. In spite of current medical advances, some forms of congenital heart disease show very high mortality rates.

Robin, Jessica; Dubayah, Ralph; Sparrow, Elena; Levine, Elissa

2008-03-01

This work evaluates whether continuity between Advanced Very High Resolution Radiometer (AVHRR) and Moderate Resolution Imaging Spectroradiometer (MODIS) normalized difference vegetation index (NDVI) is achievable for monitoring phenological changes in Alaska. This work also evaluates whether NDVI can detect changes in start of the growing season (SOS) in this region. Six quadratic regression models with NDVI as a function of accumulated growing degree days (AGDD) were developed from 2001 through 2004 AVHRR and MODIS NDVI data sets for urban, mixed, and forested land covers. Model parameters determined NDVI values for start of the observational period as well as peak and length of the growing season. NDVI values for start of the growing season were determined from the model equations and field observations of SOS made by GLOBE students and researchers at University of Alaska Fairbanks. AGDD was computed from daily air temperature. AVHRR and MODIS models were significantly different from one another with differences in the start of the observational season as well as start, peak, and length of the growing season. Furthermore, AGDD for SOS was significantly lower during the 1990s than the 1980s. NDVI values at SOS did not detect this change. There are limitations with using NDVI to monitor phenological changes in these regions because of snow, the large extent of conifers, and clouds, which restrict the composite period. In addition, differing processing and spectral characteristics restrict continuity between AVHRR and MODIS NDVI data sets.

Objective. To investigate the relationship between binge eating behavior and weight loss maintenance over a two-year period in adults. Design. Secondary data analysis using the Keep It Off study, a randomized trial evaluating an intervention to promote weight loss maintenance. Participants. 419 men and women (ages: 20 to 70 y; BMI: 20–44 kg/m2) who had intentionally lost ≥10% of their weight during the previous year. Measurements. Body weight was measured and binge eating behavior over the past 6 months was reported at baseline, 12 months and 24 months. Height was measured at baseline. Results. Prevalence of binge eating at baseline was 19.4% (n = 76). Prevalence of binge eating at any time point was 30.1% (n = 126). Although rate of weight regain did not differ significantly between those who did or did not report binge eating at baseline, binge eating behavior across the study period (additive value of presence or absence at each time point) was significantly associated with different rates of weight regain. Conclusion. Tailoring weight loss maintenance interventions to address binge eating behavior is warranted given the prevalence and the different rates of weight regain experienced by those reporting this behavior.

Bagchi, Samik; Biswas, Rima; Nandy, Tapas

2010-09-01

Development of an Anammox (anaerobic ammonium oxidation) process using non-acclimatized sludge requires a long start-up period owing to the very slow growth rate of Anammox bacteria. This article addresses the issue of achieving a shorter start-up period for Anammox activity in a well-mixed continuously stirred tank reactor (CSTR) using non-acclimatized anaerobic sludge. Proper selection of enrichment conditions and low stirring speed of 30 +/- 5 rpm resulted in a shorter start-up period (82 days). Activity tests revealed the microbial community structure of Anammox micro-granules. Ammonia-oxidizing bacteria (AOB) were found on the surface and on the outer most layers of granules while nitrite-oxidizing bacteria (NOB) and Anammox bacteria were present inside. Fine-tuning of influent NO2(-)/NH4+ ratio allowed Anammox activity to be maintained when mixed microbial populations were present. The maximum nitrogen removal rate achieved in the system was 0.216 kg N/(m(3) day) with a maximum specific nitrogen removal rate of 0.434 g N/(g VSS day). During the study period, Anammox activity was not inhibited by pH changes and free ammonia toxicity.

Cognitive changes in people with temporal lobe epilepsy over a 13-year period.

PubMed

Mameniškienė, Rūta; Rimšienė, Justė; Puronaitė, Roma

2016-10-01

The aims of our study were to evaluate cognitive decline in people with temporal lobe epilepsy over a period of 13years and to determine what clinical and treatment characteristics may have been associated with these. Thirty-three individuals with temporal lobe epilepsy underwent the same neuropsychological assessment of verbal and nonverbal memory, attention, and executive functions using the same cognitive test battery as one used 13years ago. Long-term verbal and nonverbal memory was tested four weeks later. Results were compared with those carried out 13years earlier. There was no significant change in verbal and verbal-logical memory tests; however, nonverbal memory worsened significantly. Long-term verbal memory declined for 21.9% of participants, long-term verbal-logical memory for 34.4%, and long-term nonverbal memory for 56.3%. Worsening of working verbal and verbal-logical memory was associated with longer epilepsy duration and lower levels of patients' education; worsening of verbal delayed recall and long-term verbal-logical memory was associated with higher seizure frequency. Decline in long-term nonverbal memory had significant association with a longer duration of epilepsy. The worsening of reaction and attention inversely correlated with the symptoms of depression. Over a 13-year period, cognitive functions did not change significantly. Good seizure control and reduced symptoms of depression in this sample of people with temporal lobe epilepsy were associated with better cognitive functioning. The predictors of change of cognitive functions could be complex and require further study. Copyright © 2016 Elsevier Inc. All rights reserved.

Insufficient sleep is a serious problem in adolescents and school start time is thought to be a key contributor. This study provided the first comprehensive assessment of school start times across Canada and examined whether school start times were associated with sleep duration and tiredness among adolescents. We collected information on school start times from 362 schools that participated in the 2013/2014 Health Behaviour in School-aged Children study. We calculated sleep duration from weekday bedtime and wake time reported by 29 635 students (aged 10-18 years). We classified weekday sleep as sufficient if it met national recommendations, and used data on self-reported tiredness at school in the morning. Random-effects regression models estimated the association of school start time with sleep duration, sleep sufficiency and tiredness. On average, schools started at 08:43 hours. Students slept an average of 8:36 h on weekdays and 69% met sleep duration recommendations, but 60% reported feeling tired in the morning. Every 10-min delay in school start time corresponded with 3.2 [95% confidence interval (CI): 2.0, 4.5] additional minutes of sleep, a 1.6% (95% CI: 0.5, 2.8) greater probability of sufficient sleep and a 2.1% (95% CI: 1.0, 3.2) smaller probability of feeling tired at school in the morning. Students from schools that started later slept longer, were more likely to meet sleep recommendations and were less likely to report feeling tired in the morning. The study adds weight to the mounting evidence that delaying school start time benefits adolescent sleep. © 2016 European Sleep Research Society.

Van Leuven, Susan; Allen, Harriet; Slavin, Kate

This report covers the results of the western pond turtle head-starting and reintroduction project for the period of October 2003-September 2004. Wild hatchling western pond turtles from the Columbia River Gorge were reared at the Woodland Park and Oregon Zoos in 2003 and 2004 as part of the recovery effort for this Washington State endangered species. The objective of the program is to reduce losses to introduced predators like bullfrogs and largemouth bass by raising the hatchlings to a size where they are too large to be eaten by most of these predators. Sixty-nine turtles were over-wintered at the Woodlandmore » Park Zoo and 69 at the Oregon Zoo. Of these, 136 head-started juvenile turtles were released at three sites in the Columbia Gorge in 2004. Two were held back to attain more growth in captivity. Thirty-four were released at the Klickitat ponds, 19 at the Klickitat lake, 21 at the Skamania site, and 62 at Pierce National Wildlife Refuge (NWR). This brought the total number of head-start turtles released since 1991 to 246 for the Klickitat ponds, 114 for the Klickitat lake, 167 for the Skamania pond complex, and 250 at Pierce NWR. In 2004, 32 females from the two Columbia Gorge populations were equipped with transmitters and monitored for nesting activity. Twenty-one of the females nested and produced 85 hatchlings. The hatchlings were collected in September and October and transported to the Woodland Park and Oregon zoos for rearing in the head-start program. Data collection for a four-year telemetry study of survival and habitat use by juvenile western pond turtles at Pierce NWR concluded in 2004. Radio transmitters on study animals were replaced as needed until all replacements were in service; afterward, the turtles were monitored until their transmitters failed. The corps of study turtles ranged from 39 in August 2003 to 2 turtles at the end of August 2004. These turtles showed the same seasonal pattern of movements between summer water and upland

Background Cardiovascular diseases are the leading cause of death in Brazil. The better understanding of the spatial and temporal distribution of mortality from cardiovascular diseases in the Brazilian elderly population is essential to support more appropriate health actions for each region of the country. Objective To describe and to compare geospatially the rates of mortality from cardiovascular disease in elderly individuals living in Brazil by gender in two 5-year periods: 1996 to 2000 and 2006 to 2010. Methods This is an ecological study, for which rates of mortality were obtained from DATASUS and the population rates from the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística). An average mortality rate for cardiovascular disease in elderly by gender was calculated for each period. The spatial autocorrelation was evaluated by TerraView 4.2.0 through global Moran index and the formation of clusters by the index of local Moran-LISA. Results There was an increase, in the second 5-year period, in the mortality rates in the Northeast and North regions, parallel to a decrease in the South, South-East and Midwest regions. Moreover, there was the formation of clusters with high mortality rates in the second period in Roraima among females, and in Ceará, Pernambuco and Roraima among males. Conclusion The increase in mortality rates in the North and Northeast regions is probably related to the changing profile of mortality and improvement in the quality of information, a result of the increase in surveillance and health care measures in these regions.

Hydrologic drought of water year 2011 compared to four major drought periods of the 20th century in Oklahoma

USGS Publications Warehouse

Shivers, Molly J.; Andrews, William J.

2013-01-01

Water year 2011 (October 1, 2010, through September 30, 2011) was a year of hydrologic drought (based on streamflow) in Oklahoma and the second-driest year to date (based on precipitation) since 1925. Drought conditions worsened substantially in the summer, with the highest monthly average temperature record for all States being broken by Oklahoma in July (89.1 degrees Fahrenheit), June being the second hottest and August being the hottest on record for those months for the State since 1895. Drought conditions continued into the fall, with all of the State continuing to be in severe to exceptional drought through the end of September. In addition to effects on streamflow and reservoirs, the 2011 drought increased damage from wildfires, led to declarations of states of emergency, water-use restrictions, and outdoor burning bans; caused at least $2 billion of losses in the agricultural sector and higher prices for food and other agricultural products; caused losses of tourism and wildlife; reduced hydropower generation; and lowered groundwater levels in State aquifers. The U.S. Geological Survey, in cooperation with the Oklahoma Water Resources Board, conducted an investigation to compare the severity of the 2011 drought with four previous major hydrologic drought periods during the 20th century – water years 1929–41, 1952–56, 1961–72, and 1976–81. The period of water years 1925–2011 was selected as the period of record because few continuous record streamflow-gaging stations existed before 1925, and gaps in time existed where no streamflow-gaging stations were operated before 1925. In water year 2011, statewide annual precipitation was the 2d lowest, statewide annual streamflow was 16th lowest, and statewide annual runoff was 42d lowest of those 87 years of record. Annual area-averaged precipitation totals by the nine National Weather Service climate divisions from water year 2011 were compared to those during four previous major hydrologic drought

1983-08-01

Hydrazine levels in formulations of hydralazine, isoniazid, and phenelzine have been measured over a 2-year period under ambient conditions and under temperature and humidity stress. Hydralazine tablets are stable under ambient conditions, but the hydrazine level in an injectable formulation increased from 4.5 to 10 micrograms/ml over a 23-month period. Isoniazid tablets are also stable, but hydrazine levels in an elixir and a pyridoxine combination product doubled to 44 micrograms/ml and 19 micrograms/tablet, respectively. Levels in phenelzine tablets appeared to remain constant at approximately 60 micrograms/tablet, with considerable tablet-to-tablet variation.

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

Objectives We reproduced a frequently cited study that was published in the British Medical Journal (BMJ) in 1981 assessing the extent of ‘snow-and-ice’ fractures during the winter period. Setting This study aims to provide an insight into how things have changed within the same emergency department (ED) by comparing the findings of the BMJ paper published 33 years ago with the present date. Participants As per the original study, all patients presenting to the ED with a radiological evidence of fracture during three different 4-day periods were included. The three 4-day periods included 4 days of snow-and-ice conditions and two control 4-day periods when snow and ice was not present; the first was 4 days within the same year, with a similar amount of sunshine hours, and the second was 4 days 1 calendar year later. Primary and secondary outcome measures To identify the frequency, distribution and pattern of fractures sustained in snow-and-ice conditions compared to control conditions as well as comparisons with the index study 33 years ago. Results A total of 293 patients with fractures were identified. Overall, there was a 2.20 (CI 1.7 to 3.0, p <0.01) increase in risk of fracture during snow-and-ice periods compared to control conditions. There was an increase (p <0.01) of fractures of the arm, forearm and wrist (RR 3.2 (CI 1.4 to 7.6) and 2.9 (CI 1.5 to 5.4) respectively). Conclusions While the relative risk was not of the magnitude 33 years ago, the overall number of patients presenting with a fracture during snow-and-ice conditions remains more than double compared to control conditions. This highlights the need for improved understanding of the impact of increased fracture burden on hospitals and more effective preventative measures. PMID:27630066

Beginning school is an important milestone for children. Children's readiness for school involves cognitive, physical, and emotional development. Certain school programs allow children to start first grade after 66 months of age, together with 72 month-old children. In order to estimate school readiness, we screened children before starting first grade and compared their school performance according to their age and socio-demographic characteristics. Marmara School Readiness, Denver II developmental screening, and language assessment tests were applied. Language delays were more frequent and school readiness test scores were lower in the younger group compared to older children. However, school achievement did not differ between the two age groups. Preschool education, parental income and education affected performance in most tests. Preschool screening seems effective in detecting children with lower than average developmental skills, and the school system may provide a practical opportunity for providing support to those children.

Spontaneous bacterial peritonitis is a serious complication in cirrhotic patients, and changes in the microbiological characteristics reported in the last years are impacting the choice of antibiotic used for treatment. The aim of the present study is to evaluate the changes in the epidemiology and bacterial resistance of the germs causing spontaneous bacterial peritonitis over three different periods over 17 years. All cirrhotic patients with spontaneous bacterial peritonitis and positive culture of ascites fluid were retrospectively studied in a reference Hospital in Southern Brazil. Three periods were ramdomly evaluated: 1997-1998, 2002-2003 and 2014-2015. The most frequent infecting organisms and the sensitivity in vitro to antibiotics were registered. In the first period (1997-1998) there were 33 cases, the most common were: E. coli in 13 (36.11%), Staphylococcus coagulase-negative in 6 (16.66%), K. pneumoniae in 5 (13.88%), S. aureus in 4 (11.11%) and S. faecalis in 3 (8.33%). In the second period (2002-2003), there were 43 cases, the most frequent were: Staphylococus coagulase-negative in 16 (35.55%), S. aureus in 8 (17.77%), E. coli in 7 (15.55%) and K. pneumoniae in 3 (6.66%). In the third period (2014-2015) there were 58 cases (seven with two bacteria), the most frequent were: E. coli in 15 (23.1%), S. viridans in 12 (18.5%), K. pneumoniae in 10 (15.4%) and E. faecium 5 (7.7%). No one was using antibiotic prophylaxis. Considering all staphylococci, the prevalence increased to rates of the order of 50% in the second period, with a reduction in the third period evaluated. Likewise, the prevalence of resistant E. coli increased, reaching 14%. There was a modification of the bacterial population causing spontaneous bacterial peritonitis, with high frequency of gram-positive organisms, as well as an increase in the resistance to the traditionally recommended antibiotics. This study suggests a probable imminent inclusion of a drug against gram

This research report presents findings on 'start in life' from a qualitative study of 90-year-olds from the Lothian Birth Cohort 1921. The study aimed to contextualise the LBC1921 cohort in time and place, describe cohort members' experiences of family and schooling and stimulate further inquiry into the relationships between 'start in life' and risk and resilience factors relating to longevity and healthy ageing. Scottish education and family life in the early 1930s are briefly described. Life review questionnaire: A qualitative Life Review Questionnaire was developed, requiring free-text handwritten responses. Its 'Start in Life' section focused on schooling and family support. Wave 4 of the Lothian Birth Cohort 1921 involved testing 129 members near to their 90(th) birthday. They reside largely in Edinburgh and its environs. The Life Review Questionnaire was administered to 126 participants, 54 % women. Qualitative analysis: Thematic analysis was the qualitative technique used to categorise, code and extract meaning from questionnaire text. Narratives were extracted from the data to present illustrative stories. Narratives of start in life gave contextual description. Thematic analysis showed LBC1921 members enjoying their schooling, highlighting teachers, academic achievement, school activities and school friendships. Personal qualities, family circumstances and aspects of schooling sometimes hindered educational performance. Family life was recalled mostly with warmth and parents were often portrayed as valuing education and supporting learning and development. Family adversity from poverty, parental illness and parental death was often mitigated by support from parents (or the remaining parent). Overall, most cohort members believed that they had got off to a good 'start in life'. This qualitative investigation of 'start in life' adds context and richness to quantitative investigations of the sizeable LBC1921 cohort, stimulating fresh insights and hypotheses

Baker, Jason K.; Smith, Leann E.; Greenberg, Jan S.; Seltzer, Marsha Mailick; Taylor, Julie Lounds

2010-01-01

In a previous study from our laboratory, high levels of maternal criticism predicted increased behavior problems in adolescents and adults with autism spectrum disorders (ASD) over an 18-month period (Greenberg, Seltzer, Hong, & Orsmond, 2006). The current investigation followed these families over a period of seven years to examine the longitudinal course of criticism and behavior problems, to assess the association between their trajectories, and to determine the degree to which change in each of these factors predicted levels of criticism and behavior problems at the end of the study period. A sample of 118 mothers co-residing with their adolescents and adults with ASD provided open-ended narratives about their children and reported on the children's behavior problems at four waves. Maternal criticism was derived from expressed emotion ratings of the narratives. Criticism exhibited low but significant stability over the seven year period and behavior problems exhibited high stability. Using latent growth curve modeling, (a) criticism was found to have increased over time, but only for the group of families in which the sons or daughters transitioned from high school services during the study period, (b) individual changes in criticism and behavior problems were positively correlated over the seven-year period, and (c) changes in criticism predicted levels of behavior problems at the conclusion of the study. Changes in behavior problems were not predictive of end levels of criticism. Implications for intervention and prevention efforts are discussed. PMID:21319925

This work uses data from the 1976-77 Mexican Fertility Survey, the 1982 National Demographic Survey, and the 1987 National Fertility and Health Survey to analyze fertility and contraceptive behavior among Mexican women in the 2 5-year periods from 1976-82 and 1982-87. The proportion of fertile-aged women in union using a method increased from 41.6% in 1976-77 to 58.8% in 1982 and 61.4% in 1989. The most significant gains in use of the more effective methods as in contraceptive prevalence occurred in the 1st 5-year period. The proportion of women sterilized increased from 3.73% in 1977 to 16.6% in 1982 and 21.7% in 1987, equivalent to increases over the 2 5-year periods of 345.7% and 30.7%. Female sterilization was the only method whose use increased constantly over the period. Use of the IUD was almost unchanged between 1977-82, while use of oral contraceptives and injectables both declined from 1982 to 1987 after increasing over the preceding 5 years. Contraceptive usage increased intensely in all subgroups of women studied between 1976-82, but in the 2nd period from 1982 to 1987 contraceptive usage declined significantly in some subgroups. Contraceptive prevalence among women in urban and metropolitan areas increased systematically after 1977. Rural women increased their use from 22.5% in 1977 to 48.6% in 1982. 5 years later the proportion of rural users had declined to 45.3% although it was still well above the level of 1976-77. The most significant increase in contraceptive usage among illiterate women and those with primary educations occurred from 1976 to 1982. In 1987 women with primary and higher levels of education demonstrated increases in contraceptive usage compared with 1982, but contraceptive usage among illiterate women declined from 40.8% in 1982 to 28.9% in 1987. Data from the 3 surveys demonstrate low but increasing rates of use among women 15-19 years old, who may be in the process of developing a new fertility pattern characterized by longer

This study aimed to investigate the degree of research outcome in medical science subjects in Pakistan during the period 1996-2012. In this study, the research papers published in various global science journals during the period 1996-2012 were accessed. We recorded the total number of research documents having an affiliation with a Pakistan. The main source for information was Institute of Scientific Information (ISI) Web of Science, Thomson Reuters and SCI-mago/Scopus. In global science, Pakistan contributed 58133 research papers in all science and social sciences both in ISI and non ISI indexed journals. However, in medical sciences the total number of research papers from Pakistan are 25604, citable documents 23874, citations 128061, mean citations per documents 6.45 and mean Hirsch index is 35.33. In Pakistan, the upward trend of articles published in global medical science was from the period 1996-2008. However, from 2008 the trend is markedly declined. Pakistan significantly improved its international ranking positions in research during the period 2000-2008. However, the upward trend of research papers published in global medical science could not be retained and from the year 2008 the trend started declining. This trend of research papers further declined in year 2012 compared to year 2011. It is suggested that, Pakistan must take strategic steps to enhance the research culture and increase the research and development expenditure in the country.

To establish whether sleep, health, mood, behavior, and academics improved after a 45-minute delay in high school start time, and whether changes persisted longitudinally. We collected data from school records and student self-report across a number of domains at baseline (May 2012) and at two follow-up time points (November 2012 and May 2013), at a public high school in upstate New York. Students enrolled during academic years (AY) 2011-2012 and 2012-2013 completed the Pittsburgh Sleep Quality Index; the DASS-21; the "Owl-Lark" Scale; the Daytime Sleepiness Index; and a brief self-report of health. Reports from school records regarding attendance, tardiness, disciplinary violations, and academic performance were collected for AY 2010-2011 through 2013-2014. Students delayed but did not extend their sleep period; we found lasting improvements in tardiness and disciplinary violations after the start-time delay, but no changes to other variables. At the first follow-up, students reported 20 minutes longer sleep, driven by later rise times and stable bed times. At the second follow-up, students maintained later rise times but delayed bedtimes, returning total sleep to baseline levels. A delay in rise time, paralleling the delay in the start time that occurred, resulted in less tardiness and decreased disciplinary incidents, but larger improvements to sleep patterns may be necessary to affect health, attendance, sleepiness, and academic performance. Later start times improved tardiness and disciplinary issues at this school district. A delay in start time may be a necessary but not sufficient means to increase sleep time and may depend on preexisting individual differences.

To compare work-loss in RA patients starting their first biologic with high vs moderate disease activity. We identified all RA patients aged 20-63 years in the Swedish Biologics Register who started their first biologic 2007-09 with high disease activity (DAS28 >5.1; n = 868) or moderate disease activity (DAS28 3.2-5.1; n = 854). Work days lost, defined as sick leave and disability pension days from the Swedish Social Insurance Agency, were assessed over 5 years after first bio-start. We estimated between-group mean differences adjusted for age, sex, calendar year, education level, disease duration, comorbidities and work-loss the month before bio-start. During 5 years after anti-TNF start, mean monthly work days lost declined from 16.0 to 9.2 (42%; P < 0.001) in patients with high disease activity at baseline and from 12.0 to 7.2 (40%; P < 0.001) in patients with moderate disease activity, with no between-group difference (adjusted mean difference 0.81; 95% CI - 0.44, 2.05). Accumulated 5-year work-loss was, however, higher in the high activity group (724 vs 548 days; adjusted mean difference 70; 95% CI 20, 120), but after stratification on baseline disability pension status, no differences in accumulated work-loss were detected. Substantial work-loss was seen in both patients with high and patients with moderate disease activity at anti-TNF start, with a 5-year decline in mean monthly work days lost by ∼40% in both groups and no between-group difference. Accumulated work-loss over 5 years was higher in the high-activity group, which may be explained by differences in baseline disability pension status. © The Author 2015.

Regional demographics of spinal cord injuries (SCIs) are fundamental to identifying and implementing appropriate preventive measures. The current study was conducted as a longitudinal analysis of all patients with SCIs admitted to the Hyogo Rehabilitation Center over a 19-year period. The sex and age of the patient, time and nature of injury (i.e., cause, level, and extent), and period from injury to admission were evaluated retrospectively. Pertinent tests, including Poisson regression analysis, and the Cochran-Armitage, Kruskal-Wallis, and chi-square tests, were applied to assess demographic variables, with statistical significance set at p < 0.05. Between 1995 and 2013, a total of 632 patients with SCIs (predominantly male and largely < 60 years old) were admitted to our center for rehabilitation. Although the male: female ratio remained unchanged throughout the study period, the ratio of older adults increased over time. In assessing the cause of injury, the majority of the patients involved in road traffic accidents were aged ≤ 44 years, whereas patients aged ≥ 45 years accounted for the majority of low-distance falls and disease-related SCIs, the proportions of which gradually increased. Complete paralysis and paraplegia primarily occurred in patients aged ≤ 44 years, whereas the majority of incomplete injuries and tetraplegia were limited to those aged ≥ 45 years. The patient age at the time of SCI and the nature of the injury sustained were interrelated. Age-specific strategies thus offered the best means of preventing/reducing the incidence of SCIs in Hyogo prefecture.

Coastal sandy ecosystems are increasingly being threatened by human pressure, causing loss of biodiversity, habitat degradation and landscape modifications. However, there are still very few detailed studies focussing on compositional changes in coastal dune plant communities over time. In this work, we investigated how coastal dune European Union (EU) habitats (from pioneer annual beach communities to Mediterranean scrubs on the landward fixed dunes) have changed during the last 20 years. Using phytosociological relevés conducted in 1989–90 and in 2010–12, we investigated changes in floristic composition over time. We then compared plant cover and the proportion of ruderal, alien and habitat diagnostic species (‘focal species’) in the two periods. Finally, we used Ellenberg indicator values to define the ‘preferences’ of the plant species for temperature and moisture. We found that only fore dune habitats showed significant differences in species cover between the two time periods, with higher plant cover in the more recent relevés and a significant increase in thermophilic species. Although previous studies have demonstrated consistent habitat loss in this area, we observed that all coastal dune plant communities remain well represented, after a 20-year period. However, fore dunes have been experiencing significant compositional changes. Although we cannot confirm whether the observed changes are strictly related to climatic changes, to human pressure or to both, we hypothesize that a moderate increment in average yearly temperature may have promoted the increase in plant cover and the spread of thermophilic species. Thus, even though human activities are major driving forces of change in coastal dune vegetation, at the community scale climatic factors may also play important roles. Our study draws on re-visitation studies which appear to constitute a powerful tool for the assessment of the conservation status of EU habitats. PMID:25750408

Patients initiating warfarin therapy generally experience a dose-titration period of weeks to months, during which time they are at higher risk of both thromboembolic and bleeding events. Accurate prediction of prolonged dose titration could help clinicians determine which patients might be better treated by alternative anticoagulants that, while more costly, do not require dose titration. A prediction model was derived in a prospective cohort of patients starting warfarin (n = 390), using Cox regression, and validated in an external cohort (n = 663) from a later time period. Prolonged dose titration was defined as a dose-titration period >12 weeks. Predictor variables were selected using a modified best subsets algorithm, using leave-one-out cross-validation to reduce overfitting. The final model had five variables: warfarin indication, insurance status, number of doctor's visits in the previous year, smoking status, and heart failure. The area under the ROC curve (AUC) in the derivation cohort was 0.66 (95%CI 0.60, 0.74) using leave-one-out cross-validation, but only 0.59 (95%CI 0.54, 0.64) in the external validation cohort, and varied across clinics. Including genetic factors in the model did not improve the area under the ROC curve (0.59; 95%CI 0.54, 0.65). Relative utility curves indicated that the model was unlikely to provide a clinically meaningful benefit compared with no prediction. Our results suggest that prolonged dose titration cannot be accurately predicted in warfarin patients using traditional clinical, social, and genetic predictors, and that accurate prediction will need to accommodate heterogeneities across clinical sites and over time.

To explore mortality of French professional male firefighters. Standardized mortality ratios (SMR) were calculated for 10,829 professional male firefighters employed in 1979 and compared with the French male population between 1979-2008. Firefighters were identified from 89 French administrative departments (93% of population). One thousand six hundred forty two deaths were identified, representing significantly lower all-cause mortality than in the general population (SMR = 0.81; 95%CI: 0.77-0.85). SMR increased with age and was not different from 1 for firefighters >70 years. No significant excess of mortality was observed for any specific cause, but a greater number of deaths than expected were found for various digestive neoplasms (rectum/anus, pancreas, buccal-pharynx, stomach, liver, and larynx). We observed lower all and leading-cause mortality likely due to the healthy worker effect in this cohort, with diseases of the respiratory system considerably lower (SMR = 0.57). Non-significant excesses for digestive neoplasms are notable, but should not be over-interpreted at this stage. © 2015 Wiley Periodicals, Inc.

Phieffer, Laura; Hefner, Jennifer L; Rahmanian, Armin; Swartz, Jason; Ellison, Christopher E; Harter, Ronald; Lumbley, Joshua; Moffatt-Bruce, Susan D

Operating rooms (ORs) are costly to run, and multiple factors influence efficiency. The first case on-time start (FCOS) of an OR is viewed as a harbinger of efficiency for the daily schedule. Across 26 ORs of a large, academic medical center, only 49% of cases started on time in October 2011. The Perioperative Services Department engaged an interdisciplinary Operating Room Committee to apply Six Sigma tools to this problem. The steps of this project included (1) problem mapping, (2) process improvements to preoperative readiness, (3) informatics support improvements, and (4) continuous measurement and feedback. By June 2013, there was a peak of 92% first case on-time starts across service lines, decreasing to 78% through 2014, still significantly above the preintervention level of 49% (p = .000). Delay minutes also significantly decreased through the study period (p = .000). Across 2013, the most common delay owners were the patient, the surgeon, the facility, and the anesthesia department. Continuous and sustained improvement of first case on-time starts is attributed to tracking the FCOS metric, establishing embedded process improvement resources and creating transparency of data. This article highlights success factors and barriers to program success and sustainability.

2015-01-01

The goals of the present study were to investigate whether young children attending Head Start (N=292; Mage=4.3 years) selected peers based on their preschool competency and whether children’s levels of preschool competency were influenced by their peers’ levels of preschool competency. Children’s peer interaction partners were intensively observed several times a week over one academic year. Social network analyses revealed that children selected peer interaction partners with similar levels of preschool competency and were influenced over time by their partners’ levels of preschool competency. These effects held even after controlling for several child (e.g., sex and language) and family factors (e.g., financial strain and parent education). Implications for promoting preschool competency among Head Start children are discussed. PMID:26479545

Michoacán is one of the states with the highest occurrence of earthquakes in Mexico and it is a limit of convergence triggered by the subduction of Cocos plate over the North American plate, located in the zone of the Pacific Ocean of our country, in addition to the existence of active faults inside of the state like the Morelia-Acambay Fault System (MAFS).It is important to make a combination of seismic, paleosismological and geological studies to have good planning and development of urban complexes to mitigate disasters if destructive earthquakes appear. With statistical seismology it is possible to characterize the degree of seismic activity as well as to estimate the recurrence periods for earthquakes. For this work, seismicity catalog of Michoacán was compiled and homogenized in time and magnitude. This information was obtained from world and national agencies (SSN, CMT, etc), some data published by Mendoza and Martínez-López (2016) and starting from the seismic catalog homogenized by F. R. Zúñiga (Personal communication). From the analysis of the different focal mechanisms reported in the literature and geological studies, the seismic regionalization of the state of Michoacán complemented the one presented by Vázquez-Rosas (2012) and the recurrence periods for earthquakes within the four different seismotectonic regions. In addition, stable periods were determined for the b value of the Gutenberg-Richter (1944) using the Maximum Curvature and EMR (Entire Magnitude Range Method, 2005) techniques, which allowed us to determine recurrence periods: years for earthquakes upper to 7.5 for the subduction zone (A zone) with EMR technique and years with MAXC technique for the same years for earthquakes upper to 5 for B1 zone with EMR technique and years with MAXC technique; years for earthquakes upper to 7.0 for B2 zone with EMR technique and years with MAXC technique; and the last one, the Morelia-Acambay Fault Sistem zone (C zone) years for earthquakes

Study Objectives: To establish whether sleep, health, mood, behavior, and academics improved after a 45-minute delay in high school start time, and whether changes persisted longitudinally. Methods: We collected data from school records and student self-report across a number of domains at baseline (May 2012) and at two follow-up time points (November 2012 and May 2013), at a public high school in upstate New York. Students enrolled during academic years (AY) 2011–2012 and 2012–2013 completed the Pittsburgh Sleep Quality Index; the DASS-21; the “Owl-Lark” Scale; the Daytime Sleepiness Index; and a brief self-report of health. Reports from school records regarding attendance, tardiness, disciplinary violations, and academic performance were collected for AY 2010–2011 through 2013–2014. Results: Students delayed but did not extend their sleep period; we found lasting improvements in tardiness and disciplinary violations after the start-time delay, but no changes to other variables. At the first follow-up, students reported 20 minutes longer sleep, driven by later rise times and stable bed times. At the second follow-up, students maintained later rise times but delayed bedtimes, returning total sleep to baseline levels. A delay in rise time, paralleling the delay in the start time that occurred, resulted in less tardiness and decreased disciplinary incidents, but larger improvements to sleep patterns may be necessary to affect health, attendance, sleepiness, and academic performance. Conclusions: Later start times improved tardiness and disciplinary issues at this school district. A delay in start time may be a necessary but not sufficient means to increase sleep time and may depend on preexisting individual differences.

Improving on-time surgical starts: the impact of implementing pre-OR timeouts and performance pay.

PubMed

Martin, Luke; Langell, John

2017-11-01

Operating room (OR) time is expensive. Underutilized OR time negatively impacts efficiency and is an unnecessary cost for hospitals. The purpose of this study was to evaluate the impact of a pre-OR timeout and performance pay incentive on the frequency of on-time, first surgical starts. At a single Veterans Affairs Medical Center, we implemented a pre-OR timeout in the form of a safety-briefing checklist and a modest performance pay incentive for on-time starts (>90% compliance) for attending surgeons. Data were collected on all first-start cases beginning before implementation in 2008 and continued through 2015. Each year, an average of 960 first starts occurred across nine surgical divisions. Before implementation of either the timeout or pay incentive, only 15% of cases started on time, and by 2015, greater than 72% were on time (P < 0.001). Over the study period, there were significant improvements in on-time starts (P = 0.01), of delays <15 min (P = 0.01), and of delays 16 to 30 min (P = 0.04). The trends for delays of 31 to 60 min or >60 min were not significant (P = 0.31; P = 0.81). Assuming a loss of 7 min per case for delays <15 min and 20 min per case for delays of 16 to 30 min, the total OR time saved from implementing these measures was 37,556 min. At an estimated cost of $20/min, gross savings from this project were $751,120. Implementation of a pre-OR timeout and performance pay for on-time starts significantly improves OR utilization and reduces unnecessary costs. Published by Elsevier Inc.

Oceanic crustal carbon cycle drives 26-million-year atmospheric carbon dioxide periodicities.

Müller, R Dietmar; Dutkiewicz, Adriana

2018-02-01

Atmospheric carbon dioxide (CO 2 ) data for the last 420 million years (My) show long-term fluctuations related to supercontinent cycles as well as shorter cycles at 26 to 32 My whose origin is unknown. Periodicities of 26 to 30 My occur in diverse geological phenomena including mass extinctions, flood basalt volcanism, ocean anoxic events, deposition of massive evaporites, sequence boundaries, and orogenic events and have previously been linked to an extraterrestrial mechanism. The vast oceanic crustal carbon reservoir is an alternative potential driving force of climate fluctuations at these time scales, with hydrothermal crustal carbon uptake occurring mostly in young crust with a strong dependence on ocean bottom water temperature. We combine a global plate model and oceanic paleo-age grids with estimates of paleo-ocean bottom water temperatures to track the evolution of the oceanic crustal carbon reservoir over the past 230 My. We show that seafloor spreading rates as well as the storage, subduction, and emission of oceanic crustal and mantle CO 2 fluctuate with a period of 26 My. A connection with seafloor spreading rates and equivalent cycles in subduction zone rollback suggests that these periodicities are driven by the dynamics of subduction zone migration. The oceanic crust-mantle carbon cycle is thus a previously overlooked mechanism that connects plate tectonic pulsing with fluctuations in atmospheric carbon and surface environments.

2007-04-01

The PCDD/F concentrations and removal efficiencies achieved with air pollution control devices (APCDs) during different operating periods (start-up, normal operation, and shut-down) at an existing municipal waste incinerator (MWI) in Taiwan are evaluated via stack sampling and analysis. The MWI investigated is equipped with electrostatic precipitators (EP), wet scrubbers (WS), and selective catalytic reduction system (SCR) as APCDs. The sampling results indicate that the PCDD/F concentrations at the EP inlet during start-up period were 15 times higher than that measured during normal operation period. The PCDD/F concentration observed at shut-down period was close to that measured at normal operation period. The CO concentration was between 400 and 1000 ppm during start-up period, which was about 50 times higher compared with the normal operation. Hence, combustion condition significantly affected the PCDD/F formation concentration during the waste incineration process. In addition, the distributions of the PCDD/F congeners were similar at different operating periods. During the normal operation and shut-down periods, the EP decreases the PCDD/F concentration (based on TEQ) by 18.4-48.6%, while the removal efficiency of PCDD/Fs achieved with SCR system reaches 99.3-99.6%. Nevertheless, the PCDD/F removal efficiency achieved with SCR was only 42% during the 19-h start-up period due to the low SCR operating temperature (195 degrees C).

Objectives To demonstrate that urine cytology screening can provide relevant epidemiological data for earlier detection of urothelial cancer caused by occupational exposure. Design Prospective cohort study. Setting Industries using urothelial carcinogens in France. Urine samples were collected on site, after a work week and were analysed at the University Hospital of Clermont-Ferrand, France. Participants Participants were workers exposed to urothelial carcinogens. Women and current smokers at time of study recruitment were exclusion criteria. Outcomes Urine cells atypia were ranged into three classes: negative/normal, atypical/suspicious/dysplasia or positive/malignant. Results We included 2020 workers over a period of 20 years from 1993 to 2013: 606 worked in rubber manufacturing, 692 from metal processing, 245 in chemical industry and 477 in roadwork and building industry. Workers had a mean exposure of 15.2±10.4 years before their first urine cytology screening. There was a mean of 3.4±4.3 urine cytology screenings per worker between 1993 and 2013. 6478 cytology were normal, 462 suspicious and 13 malignant. Suspicious and malignant cytology occurred in 4.8% of workers exposed for 1–10 years, 6.2% for 11–20 years of exposure, 7.6% for 21–30 years and 8.6% for >30 years (p<0.001). Using exposure for 1–10 years as reference, the adjusted OR of receiving a suspicious or malignant diagnosis increased with duration of exposure: OR=1.50 (95% CI 1.10 to 2.05, p=0.01) for 21–30 years and OR=1.78 (95% CI 1.23 to 2.56, p=0.002) for >30 years of exposure. Using metal processing as reference, the risk of pathological urine cytology results increased for rubber manufacturing (OR=1.32, 95% CI 1.05 to 1.65, p=0.02), with a trend for roadwork and building industry (OR=1.39, 95% CI 0.98 to 1.97, p=0.07) and for chemical industry (OR=1.34, 95% CI 0.94 to 1.93, p=0.11). Conclusions Urine cytology is a useful tool in occupational medicine. We promote new

This study reports on an independent evaluation of Start Strong: Building Healthy Teen Relationships, a multicomponent initiative targeting 11- to 14-year-olds. "Start Strong" was designed to focus on the developmental needs of middle school students and to enhance skills and attitudes consistent with promotion of healthy relationships and reduction of teen dating violence (TDV). The quasi-experimental evaluation design included data collection from four Start Strong schools and four comparison schools. Student surveys were collected at four waves of data at the beginning and the end of grades 7 and 8. Multilevel models used repeated observations nested within students who were, in turn, nested within schools to determine whether participation in Start Strong enhanced healthy skills and relationships and decreased TDV-related attitudes and behaviors. Short-term effects from waves 1 to 2 were statistically significant for increased parent-child communication and boy/girlfriend relationship satisfaction and support and decreased gender stereotypes and attitudes supporting TDV. Findings for acceptance of TDV and gender stereotypes persisted longitudinally. Results are promising and illustrate that a multicomponent, community-based initiative reduced risk factors predictive of TDV. Start Strong is innovative in its focus on early adolescence, which is a critical period in the transition to dating. The results inform future intervention efforts and underscore the need for further study of middle school students. Copyright © 2015 Society for Adolescent Health and Medicine.

Why to start with eMeteorNews?

Roggemans, Paul

2016-01-01

Amateur meteor workers have always been interested to exchange information and experience. In the past this was only possible via personal contacts by letter or by specialized journals. With internet a much faster medium became available and plenty of websites, mailing lists, Facebook groups, etc., have been created in order to communicate about meteors. Today there is a wealth of meteor data circulating on internet, but the information is very scattered and not directly available to everyone. The authors have been considering how to organize an easy access to the many different meteor related publications. The best solution for the current needs of amateur meteor observers proved to be a dedicated website combined with a PDF journal, both being free available without any subscription fee or registration requirement. The authors decided to start with this project and in March 2016 the website meteornews.org has been created. A first issue of eMeteorNews has been prepared in May 2016. The year 2016 will be a test period for this project. The mission statement of this project is: “Minimizing overhead and editorial constraints to assure a swift exchange of information dedicated to all fields of active amateur meteor work.”

Periodic alternating nystagmus (PAN) is a form of horizontal jerk nystagmus characterized by periodic reversals in direction. We report a case who exhibited transient PAN induced by caloric stimulation. The patient was a 75-year-old male. He had experienced floating sensation in January 2010. Eight months later, he was referred to our university hospital. Gaze nystagmus and positional tests revealed no nystagmus. Only weak right-beating horizontal nystagmus was observed during left Dix-Hallpike maneuver. Electronystagmography showed normal saccadic and smooth pursuit eye movements. The optokinetic nystagmus pattern test was also bilaterally normal. However, during the caloric stimulation to the right ear, at 166 s from the start of irrigation, the direction of nystagmus alternated from leftward to rightward, and thereafter this reversal of direction repeated 15 times. Magnetic resonance imaging showed no significant lesion except for chronic ischemia in the brain. The patient probably had some kind of latent lesion of impaired velocity storage and exhibited transient PAN induced by caloric stimulation. Caloric stimulation is useful and simple examination to disclose latent eye movement disorders of which velocity storage mechanism is impaired. Copyright © 2013 Elsevier Ireland Ltd.

Cool-down and frozen start-up behavior of a grooved water heat pipe

NASA Technical Reports Server (NTRS)

Jang, Jong Hoon

1990-01-01

A grooved water heat pipe was tested to study its characteristics during the cool-down and start-up periods. The water heat pipe was cooled down from the ambient temperature to below the freezing temperature of water. During the cool-down, isothermal conditions were maintained at the evaporator and adiabatic sections until the working fluid was frozen. When water was frozen along the entire heat pipe, the heat pipe was rendered inactive. The start-up of the heat pipe from this state was studied under several different operating conditions. The results show the existence of large temperature gradients between the evaporator and the condenser, and the moving of the melting front of the working fluid along the heat pipe. Successful start-up was achieved for some test cases using partial gravity assist. The start-up behavior depended largely on the operating conditions.

Evolution of periodicity in periodical cicadas.

Periodical cicadas (Magicicada spp.) in the USA are famous for their unique prime-numbered life cycles of 13 and 17 years and their nearly perfectly synchronized mass emergences. Because almost all known species of cicada are non-periodical, periodicity is assumed to be a derived state. A leading hypothesis for the evolution of periodicity in Magicicada implicates the decline in average temperature during glacial periods. During the evolution of periodicity, the determinant of maturation in ancestral cicadas is hypothesized to have switched from size dependence to time (period) dependence. The selection for the prime-numbered cycles should have taken place only after the fixation of periodicity. Here, we build an individual-based model of cicadas under conditions of climatic cooling to explore the fixation of periodicity. In our model, under cold environments, extremely long juvenile stages lead to extremely low adult densities, limiting mating opportunities and favouring the evolution of synchronized emergence. Our results indicate that these changes, which were triggered by glacial cooling, could have led to the fixation of periodicity in the non-periodical ancestors.

To determine whether dietary intakes of children enrolled in Head Start programs differ from those of children not attending preschool or children in non-Head Start programs. Using data from the 1999-2004 National Health and Nutrition Examination Survey, low-income, 3- to 5-year-old children were categorized into one of four preschool groups: Head Start (n=184), non-Head Start (n=189), past preschool (n=193), and no preschool (n=384). Total nutrient intakes were calculated using 24-hour parental recalls. Mean macronutrient and micronutrient intakes were compared across groups and the percentage of children not meeting Recommended Dietary Allowances (RDAs) were calculated. Multivariate logistic regression was used to evaluate the relationship between preschool group and likelihood of not meeting dietary guidelines. Many children did not meet the RDA for folate (20.5%), vitamin A (39.7%), vitamin E (79.7%), calcium (40.2%), iron (28.8%), and potassium (90.8%). Compared with the other preschool groups, Head Start children had lower mean protein, saturated fat, riboflavin, calcium, and phosphorous intakes. The greatest differences in intake were observed between Head Start participants and no-preschool children. Multivariate analyses demonstrated an association between Head Start and inadequate intake of protein, thiamin, riboflavin, niacin, calcium, and selenium. Compared with other low-income children, those in Head Start programs appear to be at greater risk for not meeting the RDA for several key vitamins and minerals. These differences in diet quality may present an opportunity for Head Start programs to enhance nutrition in this student population. Copyright © 2011 American Dietetic Association.

To study the publication productivity of Spanish emergency physicians in the 5-year period from 2010 through 2014 and compare it with the previous period (2005-2009). Articles authored by emergency physicians affiliated with institutions in Spain were selected from the Science Citation Index-Expanded; conference presentations were excluded. We collected data for year of publication, author information, journal, the journal's impact factor (IF), type of article, cites received, and area of research. We searched at 2010-2014 period, and these data were compared with historic data from the 2005-2009 period. A total of 1433 articles were published in 2010-2014; 52.4% were original research articles (56% more than in 2005-2009, P=.01). The mean journal IF associated with the publications was slightly higher in 2010-2014 (2.587 vs 2.483 for 2005-2009). The median was slightly lower (2.295 vs 3.085 in the earlier period), but the 90th percentile was higher (4.036 vs 3.085, P=0.01), reflecting an increase in the number of publications in journals with high IFs. Most articles continue to be published in Castilian Spanish (67.8%), although the percentage of articles published in English increased significantly, from 25.2% in the previous period to 32.1% in 2010-2014; P=.001). Scientific publications in emergency medicine come mainly from specialists working in hospital emergency departments (89%). Authors affiliated with a university are in the minority, although their percentage increased significantly from 10.9% in the previous period to 16.2% in the recent one (P=.001). Collaboration increased in the recent period in all categories: between hospitals in the same Spanish autonomous community (from 24.7% to 36%), in different communities (from 10.9% to 19%), or in different countries (from 2.3% to 8.4%) (P=.001, all comparisons). The most productive research areas were cardiovascular conditions (accounting for 13.1% of the publications), infectious diseases (13

SP-100 system thaw and start-up strategies

NASA Astrophysics Data System (ADS)

Kirpich, A.; Choe, H.

The authors review several strategies that have been considered during calendar year 1990 for SP-100 system start-up and thaw, and provide results of screening analyses. Screening studies have identified three concepts which are capable of thawing the SP-100 system: (1) a heat pipe approach in which reactor-heated heat pipes are routed to equipment enclosed within a thaw cavity; (2) a bleed-tube approach in which perforated tubes routed through ducting and components achieve thaw progressively as the result of successively thawing bleed-holes; and (3) a NaK traceline approach in which reactor-heated NaK is routed along ducting and components and achieves lithium thaw by both radiative and conductive coupling methods. Key issues have been identified in connection with pump start-up, reactor and power converter transient behavior, and hydraulic circuit stability. Pump start-up stability is accomplished by a linked-pump hydraulic arrangement.

2013-09-01

This open-label extension (SP716; NCT00599196) of a 6-month, double-blind, randomized study (SP513) investigated the safety and tolerability of rotigotine transdermal system over up to ~6 years in patients with Parkinson's disease (PD; early-stage PD at double-blind enrollment). Eligible patients completing the 6-month study received optimal dose open-label rotigotine (≤ 16 mg/24 h) for up to ~6 years. Adjunctive levodopa was permitted. Primary outcomes included adverse events (AEs) and extent of rotigotine exposure. Analysis of adjunctive levodopa use, dyskinesias [unified Parkinson's disease rating scale (UPDRS) IV], and efficacy (UPDRS II + III total score) were also assessed. Of 381 patients enrolled in the open-label extension, 52 % were still in the study at time of closure; 24 % withdrew because of AEs and 6 % because of lack of efficacy. Patients received rotigotine for a median duration of 1,564.5 days (~4 years, 3 months; range 5-2, 145 days). 69 % of patients started supplemental levodopa; median time to levodopa was 485 days (~1 year, 4 months). Most common AEs (% per patient-year) were somnolence (18 %), application site reactions (12 %), nausea (9 %), peripheral edema (7 %), and fall (7 %). AEs indicative of impulsive-compulsive behavior were recorded in 25 (7 %) patients. Dyskinesias were experienced by 65 (17 %) patients; the majority [47 of 65 (72 %)] reported first dyskinesia after starting levodopa. Mean UPDRS II + III total scores remained below double-blind baseline for 4 years (assessment of all patients). In conclusion, rotigotine was generally well tolerated for up to ~6 years in patients with early-stage PD. The AEs reported were in line with previous studies of rotigotine transdermal system, with typical dopaminergic side effects and application site reactions seen.

ANITA™ Mox is a new one-stage deammonification Moving-Bed Biofilm Reactor (MBBR) developed for partial nitrification to nitrite and autotrophic N-removal from N-rich effluents. This deammonification process offers many advantages such as dramatically reduced oxygen requirements, no chemical oxygen demand requirement, lower sludge production, no pre-treatment or requirement of chemicals and thereby being an energy and cost efficient nitrogen removal process. An innovative seeding strategy, the 'BioFarm concept', has been developed in order to decrease the start-up time of new ANITA Mox installations. New ANITA Mox installations are started with typically 3-15% of the added carriers being from the 'BioFarm', with already established anammox biofilm, the rest being new carriers. The first ANITA Mox plant, started up in 2010 at Sjölunda wastewater treatment plant (WWTP) in Malmö, Sweden, proved this seeding concept, reaching an ammonium removal rate of 1.2 kgN/m³ d and approximately 90% ammonia removal within 4 months from start-up. This first ANITA Mox plant is also the BioFarm used for forthcoming installations. Typical features of this first installation were low energy consumption, 1.5 kW/NH4-N-removed, low N₂O emissions, <1% of the reduced nitrogen and a very stable and robust process towards variations in loads and process conditions. The second ANITA Mox plant, started up at Sundets WWTP in Växjö, Sweden, reached full capacity with more than 90% ammonia removal within 2 months from start-up. By applying a nitrogen loading strategy to the reactor that matches the capacity of the seeding carriers, more than 80% nitrogen removal could be obtained throughout the start-up period.

Burden of herpes zoster requiring hospitalization in Spain during a seven-year period (1998–2004)

PubMed Central

2009-01-01

Background A thorough epidemiological surveillance and a good understanding of the burden of diseases associated to VZV are crucial to asses any potential impact of a prevention strategy. A population-based retrospective epidemiological study to estimate the burden of herpes zoster requiring hospitalization in Spain was conducted. Methods This study was conducted by using data from the national surveillance system for hospital data, Conjunto Mínimo Básico de Datos (CMBD). Records of all patients admitted to hospital with a diagnosis of herpes zoster (ICD-9-MC codes 053.0–053.9) during a 7-year period (1998–2004) were selected. Results A total of 23,584 hospitalizations with a primary or secondary diagnosis of herpes zoster in patients ≥ 30 years of age were identified during the study period. Annually there were 13.4 hospitalizations for herpes zoster per 100,000 population in patients ≥ 30 years of age. The rate increases with age reaching a maximum in persons ≥ 80 years of age (54.3 admissions per 100,000 population >80 years of age). The mean cost of a hospitalization for herpes zoster in adult patients was 3,720 €. The estimated annual cost of hospitalizations for herpes zoster in patients ≥ 30 years of age in Spain was 12,731,954 €. Conclusion Herpes zoster imposes an important burden of hospitalizations and result in large cost expenses to the Spanish National Health System, especially in population older than 50 years of age PMID:19422687

Tree-ring studies from tropical to subtropical regions are rarer than that from extratropical regions, which greatly limit our understanding of some critical climate change issues. Based on the tree-ring-width chronology of samples collected from the Dabie Mountains, we reconstructed the April-June mean temperature for this region with an explained variance of 46.8%. Five cold (1861-1869, 1889-1899, 1913-1920, 1936-1942 and 1952-1990) and three warm (1870-1888, 1922-1934 and 2000-2005) periods were identified in the reconstruction. The reconstruction not only agreed well with the instrumental records in and around the study area, but also showed good resemblance to previous temperature reconstructions from nearby regions, indicating its spatial and temporal representativeness of the temperature variation in the central part of eastern China. Although no secular warming trend was found, the warming trend since 1970 was unambiguous in the Dabie Mountains (0.064 °C/year). Further temperature comparison indicated that the start time of the recent warming in eastern China was regional different. It delayed gradually from north to south, starting at least around 1940 AD in the north part, around 1970 AD in the central part and around 1980s in the south part. This work enriches the high-resolution temperature reconstructions in eastern China. We expect that climate warming in the future would promote the radial growth of alpine Pinus taiwanensis in the subtropical areas of China, therefore promote the carbon capture and carbon storage in the Pinus taiwanensis forest. It also helps to clarify the regional characteristic of recent warming in eastern China.

Airborne grass (Poaceae) pollen in southern Spain. Results of a 10-year study (1987-96).

This work reports an exhaustive study of the aerobiology of the Gramineae in Seville, Spain, which is typical of coastal Mediterranean areas. Sampling was done with a Cour trap installed on the roof terrace of the School of Pharmacy, Seville, from 1987 to 1996, both inclusive. The climatic pattern of that period was characterized by two exceptionally wet years (1989 and 1996), between which were 5 consecutive years of drought (1990-5). This typically Mediterranean climate affects grass aerobiology. The annual amounts of total grass pollen are low, never exceeding 2500 grains/m3. The start, length, and intensity of the pollen season are significantly correlated with preseasonal meteorologic factors (precipitation and temperature), but intraseasonal meteorologic conditions have no effect on the three variables. The relationships are stated by three equations that, while further years of observations are anticipated, can be considered models to forecast the characteristics of the pollen season: the starting date depends on the mean temperatures of January and February, and the length and intensity of the season depend on the rainfall between the beginning of January and the starting date of the season. For the study period, the weekly concentrations (pollen curves) throughout the year showed no typical pattern of variation over the years, so that it was impossible to make mid- and long-term forecasts of the variation in weekly concentration. The most noteworthy aspects of grass pollen curves are a long pollen season, which starts in February or March and lasts until September or October; peaks of higher concentration (> 100 grains/m3) in May and June, associated with increases in temperature and absence of precipitation; and other peaks in the summer months that may be as high as the spring peaks.

More than 7 million athletes participate in high school sports annually, with both the benefits of physical activity and risks of injury. Although catastrophic cervical spine injuries have been studied, limited data are available that characterize less-severe cervical spine injuries in high school athletes. To describe and compare cervical spine injury rates and patterns among U.S. high school athletes across 24 sports over a 10-year period. Descriptive epidemiology study. National sample of high schools participating in the High School Reporting Information Online injury surveillance system. Athletes from participating schools injured in a school sanctioned practice, competition, or performance during the 2005-2006 through 2014-2015 academic years. Cervical spine injury data captured by the High School Reporting Information Online system during the 10-year study period were examined. Cervical spine injury was defined as any injury to the cervical spinal cord, bones, nerves, or supporting structures of the cervical spine including muscles, ligaments, and tendons. Cervical spine injury rates, diagnoses, mechanisms, and severities. During the study period, 1080 cervical spine injuries were reported during 35,581,036 athlete exposures for an injury rate of 3.04 per 100,000 athlete exposures. Injury rates were highest in football (10.10), wrestling (7.42), and girls' gymnastics (4.95). Muscle injuries were most common (63.1%), followed by nerve injuries (20.5%). A larger proportion of football injuries were nerve injuries compared with all other sports (injury proportion ratio 3.31; confidence interval 2.33-4.72), whereas in boys' ice hockey fractures represented a greater proportion of injuries compared with all other sports (injury proportion ratio 7.64; confidence interval 2.10-27.83). Overall, the most common mechanisms of injury were contact with another player (70.7%) and contact with playing surface (16.1%). Cervical spine injury rates and patterns vary by sport

Regular airtightness tests were performed on 24 new houses, over periods of up to three years, to evaluate their air barrier systems and to search for evidence, air barrier degradation. Ten of the houses were constructed with polyethylene air barriers while the remaining 14 used an early version of the Airtight Drywall Approach (ADA). The 24 project houses were architecturally similar and of approximately equal size and general layout; stucco was the predominate exterior wall finish. All were exposed to similar terrain shielding. The study found that the airtightness of the polyethylene air barrier houses remained stable over their respectivemore » monitoring periods. Although two of the ten houses demonstrated possible, albeit slight, evidence of airtightness degradation, the magnitude of these changes was small and judged not to be of practical significance. With respect to the critical issue of air barrier degradation, no evidence could be found to indicate polyethylene is unsuited for use as an air barrier material in residential construction. For example, all but one of the polyethylene houses met the airtightness requirements of the Canadian R-2000 Standard for energy efficient housing at the end of their monitoring periods. The study found that the airtightness of the 14 ADA houses also remained stable over their monitoring periods. Although six of the 14 houses displayed possible, but slight, evidence of airtightness degradation, the magnitude of the changes was small and not of practical significance. It was concluded that no evidence could be found to indicate that the ADA system is unsuited for use in residential construction. All 14 ADA houses met the airtightness requirements of the R-2000 Program at the end of their respective monitoring periods.« less

Purpose: This study tested the hypothesis that volunteering in environmental organizations in midlife is associated with greater physical activity and improved mental and physical health over a 20-year period.  Design and Methods: The study used data from two waves (1974 and 1994) of the Alameda County Study, a longitudinal study of health and mortality that has followed a cohort of 6,928 adults since 1965. Using logistic and multiple regression models, we examined the prospective association between environmental and other volunteerism and three outcomes (physical activity, self-reported health, and depression), with 1974 volunteerism predicting 1994 outcomes, controlling for a number of relevant covariates.  Results: Midlife environmental volunteering was significantly associated with physical activity, self-reported health, and depressive symptoms.  Implications: This population-based study offers the first epidemiological evidence for a significant positive relationship between environmental volunteering and health and well-being outcomes. Further research, including intervention studies, is needed to confirm and shed additional light on these initial findings. PMID:20172902

Impacts of climate change on rise and fall of human civilization in the history could provide lessons for understanding how impacts of climatic change and human response interacted. However, such a study is highly restricted by lacking in high-resolution series concerning long-term social-economic processes. China is a country that has great potential for providing long-term socio-economic series in high-resolution because it has abundant related historical records as long as thousands of years in the Chinese historical literatures. In this paper, A methodology named Semantic Differential for quantifying historical literal descriptions to grade numbers is developed. Using the methodology, 10-year resolution graded series of social-economic system change of China, including harvest of agriculture, economy, social rise and fall, are reconstructed during the past 2000 years. To compare the periodic changes of climate, harvest, economy, social rise and fall in China during the past 2000 years, it is found that : (1) There are similar periods on multiple time scales among all the series. (2) On the centurial scale, the better economic and social phases generally occurred in the better harvest phases when generally had a warm climate. (3) In the warm phases, both economic and social status were recovered faster and flourished longer than that in the cold phases. (4) The direct impact of climatic change on food security could be enlarged or diminished when it transmitted from harvest I to other social-economic subsystems because of feedbacks of the system.

ABSTRACT Introduction: COPD (Chronic Obstructive Pulmonary Disease) is characterized by airflow limitation that is not fully reversible and that can lead to respiratory failure. Objective: to show the changes of arterial blood gases in COPD during the 4 -year evolution of illness. Material and Methods: The research was done on patients suffering from COPD treated at the Clinic “Podhrastovi” during 2006 and 2007 year. The tested parameters were examined from the date of receiving patient with COPD to hospital treatment in 2006 and 2007 and then followed prospectively until 2010 or 2011 year (the follow-up period was 4 years). There were total 199 treated patients who were chosen at random and regularly attended the control examinations. The study was conducted on adult patients of both sexes, different age group. In each patient the duration of illness was recorded so is sex, age, data of smoking habits, information about the regularity of taking bronchodilator therapy during remissions of disease, about the treatment of disease exacerbations, results of blood gases analysis as follows : pH value, PaO2 (partial pressure of oxygen in arterial blood), PaCO2 (partial pressure of carbon dioxide in arterial blood). All these parameters were measured at the beginning and at the end of each hospital treatment. We took in elaboration data obtained in the beginning of the first hospitalization and at the end of the last hospitalization or at the last control in outpatient department when patient was in stable state. Patients were divided into three groups according to the number of exacerbations per year. Results: there is the statistically significant decrease of PaO2 (p<0.01) and pH, (p<0.05) and an increase of PaCO2 (p<0.01) during follow-up period. But in patients regularly treated in phases of remission and exacerbations of illness the course of illness is slower. The decrease of pH and PaO2 and increase of PaCO2 is statistically significantly smaller in those

2016-06-14

The aim of this study was to analyse the mechanics of rotation and the temporal, angular and kinematics variables during the aerial phase for the kick-start with respect to the grab start. Nine elite swimmers (70.0 ± 7.7 kg; 178 ± 9.4 cm; 24.5 ± 5.3 years; 824 ± 119 FINA points scoring) performed the starts on the OMEGA OSB11 starting block followed by 5 m gliding at maximum velocity. Nineteen comparisons of kinematics variables across start technique were performed with critical alpha adjusted using a Holm's correction to maintain an experiment-wise type I error rate of p <0.05. The differences were statistically evaluated by T-test and Wilcoxon test. Significant advantages for the kick-start were observed in all temporal variables (except in the flight time) and in the vertical take-off velocity. Similarities in the centre of mass angular momentum at take-off (120.89 ± 17.66, 126.61 ± 13.51 s(-1).10(-3), p-value <0.294; kick-start and grab start) caused that KS did not increase the temporal advantages obtained on the block at 5 m distance. Two different rotational movements were found for both techniques. A displacement of the rear leg and front leg on the block and during the flight respectively permits a higher lower limbs position relative to the trunk at hands entry for kick-start. However, larger rotational movement of the trunk characterized grab start. It was concluded that shorter block times and rotational displacements of the lower limbs on the block and flight phase are the key of the best performance for kick-start at 5 m distance.

Nonradial and radial period changes of the δ Scuti star 4 CVn. II. Systematic behavior over 40 years

NASA Astrophysics Data System (ADS)

Breger, M.; Montgomery, M. H.; Lenz, P.; Pamyatnykh, A. A.

2017-03-01

Aims: Radial and nonradial pulsators on and near the main sequence show period and amplitude changes that are too large to be the product of stellar evolution. The multiperiodic δ Sct stars are well suited to study this, as the period changes of different modes excited in the same star can be compared. This requires a very large amount of photometric data covering years and decades as well as mode identifications. Methods: We have examined over 800 nights of high-precision photometry of the multiperiodic pulsator 4 CVn obtained from 1966 through 2012. Because most of the data were obtained in adjacent observing seasons, it is possible to derive very accurate period values for a number of the excited pulsation modes and to study their systematic changes from 1974 to 2012. Results: Most pulsation modes show systematic significant period and amplitude changes on a timescale of decades. For the well-studied modes, around 1986 a general reversal of the directions of both the positive and negative period changes occurred. Furthermore, the period changes between the different modes are strongly correlated, although they differ in size and sign. For the modes with known values of the spherical degree and azimuthal order, we find a correlation between the direction of the period changes and the identified azimuthal order, m. The associated amplitude changes generally have similar timescales of years or decades, but show little systematic or correlated behavior from mode to mode. Conclusions: A natural explanation for the opposite behavior of the prograde and retrograde modes is that their period changes are driven by a changing rotation profile. The changes in the rotation profile could in turn be driven by processes, perhaps the pulsations themselves, that redistribute angular momentum within the star. In general, different modes have different rotation kernels, so this will produce period shifts of varying magnitude for different modes.

We report on the baseline prevalence and severity of dental caries of children enrolled in the New Hampshire Head Start program during the 2007-2008 school year. We selected a random cluster sample of 607 children aged 3-5 years attending 27 Head Start centers across the state. Four volunteer dentists provided oral examinations and determined the presence of untreated dental caries, caries experience, and treatment urgency. Overall, 40 percent of the participating children had experienced dental caries, and 31 percent had at least one untreated decayed tooth. Approximately 22 percent of the children had evidence of maxillary anterior caries, 23 percent were in need of dental care, and < 1 percent needed urgent care. The prevalence of dental caries is comparable with that reported by Head Start programs elsewhere. The prevalence of caries affecting maxillary anterior teeth is higher. Further studies should examine state-specific barriers to dental care among this population.

Abstract Patients presenting late in the course of kidney disease who require urgent initiation of dialysis have traditionally received temporary vascular catheters followed by hemodialysis. Recent changes in Medicare payment policy for dialysis in the USA incentivized the use of peritoneal dialysis (PD). Consequently, the use of more expeditious PD for late-presenting patients (urgent-start PD) has received new attention. Urgent-start PD has been shown to be safe and effective, and offers a mechanism for increasing PD utilization. However, there has been no assessment of the dialysis-related costs over the first 90 days of care. The objective of this study was to characterize the costs associated with urgent-start PD, urgent-start hemodialysis (HD), or a dual approach (urgent-start HD followed by urgent-start PD) over the first 90 days of treatment from a provider perspective. A survey of practitioners from 5 clinics known to use urgent-start PD was conducted to provide inputs for a cost model representing typical patients. Model inputs were obtained from the survey, literature review, and available cost data. Sensitivity analyses were also conducted. The estimated per patient cost over the first 90 days for urgent-start PD was $16,398. Dialysis access represented 15% of total costs, dialysis services 48%, and initial hospitalization 37%. For urgent-start HD, total per patient costs were $19,352, and dialysis access accounted for 27%, dialysis services 42%, and initial hospitalization 31%. The estimated cost for dual patients was $19,400. Urgent-start PD may offer a cost saving approach for the initiation of dialysis in eligible patients requiring an urgent-start to dialysis.

A new approach to the study of work ability is an individually oriented approach. This approach increases our understanding of how work ability develops over time among individuals with a different level of work ability. To increase knowledge about individuals' work ability trajectories by studying hospital nurses' development of work ability over a 2 year period and factors associated with these trajectories. We used a data set of a prospective cohort study of hospital nurses, which was surveyed for 2 years by means of three questionnaires on work characteristics, health and work ability. The outcome variable was the general work ability trajectory over the course of 2 years (favourable/unfavourable). The predictors were the individual, physical and mental work ability and health characteristics at baseline. A multivariate backwards stepwise logistic regression analysis was used. Of 572 nurses in the cohort, nearly one-third (31%, 179/572) showed an unfavourable general work ability trajectory. Low physical work ability (odds ratio (OR) 1.82; 95% confidence interval (95% CI) 1.12-2.95) and high level of fatigue (OR 1.52; 95% CI 0.97-2.40) at baseline were predictors for the unfavourable course of self-reported general work ability. A substantial proportion of this cohort of hospital nurses experienced a reduction in work ability over the course of 2 years. Baseline physical work ability and level of fatigue were related to this. The next step is to address these factors when counselling nurses and evaluate the effect of interventions aimed at improving physical work ability and reducing fatigue. © The Author 2015.

Ulcerative colitis (UC) is a chronic disease with a heterogeneous clinical evolution. The prevalence and incidence of UC vary widely and depend on multiple factors including ethnicity and geographic location. To determine the frequency of new cases of UC and their clinical characteristics in a large cohort from a referral hospital in Mexico City. Patients with confirmed diagnosis of UC were included during a period between January 1987 and December 2006. Demographic and clinical data were collected from medical records. A total of 848 new cases of UC were diagnosed during a 20-year period. All the patients had endoscopic and histologic confirmation. The mean of annual new UC cases increased from 28.8 in the first period (1987 to 1996) to 76.1 in the second period (1997 to 2006) (P<0.00008). The incidence of new cases increased 2.6-fold comparing both periods of time. This study consisted of 467 females and 382 males, with a mean age at diagnosis of 31.3+/-12.3 years. The clinical manifestations were pancolitis (59.1%), and extraintestinal manifestations (41.5%). Most of the patients, 762 (89.8%) were taking sulfasalazine or 5-aminosalicylic acid, 282 (33.3%) used oral or systemic steroids, 237 (28%) were taking azathioprine. The frequency of new UC cases has increased significantly in the last 10 years in Mexico, largely due to the unique genetic make-up and the environmental factors (infectious diseases including parasites) not found in other countries.

To explore the variation in ovarian cancer survival in Denmark in the period 1978-2002 in relation to time since diagnosis, age at diagnosis, period of diagnosis, stage and histology. Register-based cohort study. Denmark in the period 1978-2002. Using the nationwide Danish Cancer Registry, we included a total of 13,035 women diagnosed with invasive ovarian cancer in Denmark in the period 1978-2002. Excess mortality risk analyses of five-year relative survival of ovarian cancer patients diagnosed in the period 1978-2002 with follow-up through 2006 were made based on data from the NORDCAN database. Five-year relative survival, excess mortality rate (ER) and relative excess mortality risk (RER) after an ovarian cancer diagnosis. The relative survival of Danish ovarian cancer patients slightly increased in the period 1978-2002. The ERs were highest in the first year following diagnosis, in particular in the first three months, and among older patients, even for localized and regional tumors. The pattern remained the same when stratified by histological subgroup. Older age at diagnosis, earlier period of diagnosis, more advanced stage at diagnosis and being diagnosed with undifferentiated carcinoma predicted poorer survival among Danish ovarian cancer patients diagnosed in the period 1978-2002. The survival of Danish ovarian cancer patients has slightly increased from 1978 through 2002. Despite this, the mortality rate of ovarian cancer in Denmark is still higher than in the other Nordic countries. Explanations for these differences are still to be identified.

To determine the effect of the Early Start Denver Model (ESDM) for treatment of young children with autism on health care service use and costs. We used data from a randomized trial that tested the efficacy of the ESDM, which is based on developmental and applied behavioral analytic principles and delivered by trained therapists and parents, for 2 years. Parents were interviewed about their children's service use every 6 months from the onset of the intervention to follow-up (age 6 years). The sample for this study consisted of 39 children with autism who participated in the original randomized trial at age 18 to 30 months, and were also assessed at age 6 years. Of this sample, 21 children were in the ESDM group, and 18 children were in the community care (COM) group. Reported services were categorized and costed by applying unit hourly costs. Annualized service use and costs during the intervention and post intervention for the two study arms were compared. During the intervention, children who received the ESDM had average annualized total health-related costs that were higher by about $14,000 than those of children who received community-based treatment. The higher cost of ESDM was partially offset during the intervention period because children in the ESDM group used less applied behavior analysis (ABA)/early intensive behavioral intervention (EIBI) and speech therapy services than children in the comparison group. In the postintervention period, compared with children who had earlier received treatment as usual in community settings, children in the ESDM group used less ABA/EIBI, occupational/physical therapy, and speech therapy services, resulting in significant cost savings in the amount of about $19,000 per year per child. Costs associated with ESDM treatment were fully offset within a few years after the intervention because of reductions in other service use and associated costs.

The epidemiology of classical Hodgkin lymphoma varies significantly in populations with different socioeconomic conditions. Among other changes, improvement in such conditions leads to a reduction in the association with EBV infection and predominance of the nodular sclerosis subtype. This study provides an overview of the epidemiology of 817 cases of classical Hodgkin lymphoma diagnosed in five reference hospitals of the State of Sao Paulo, Brazil, over 54 years (1954-2008). The cases were distributed in 3 periods (1954-1979; 1980-1999; and 2000-2008). EBV-positive cases decreased from 87% to 46%. In children and adolescents (<15 years) and in young adults (15-45 years), EBV-positive cases decreased respectively from 96% to 64%, and from 85% to 32%. The percentage of male patients declined from 80% to 58%. In older patients (>45 years), the decrease in EBV infection was not significant. Nodular Sclerosis was the most common subtype in all periods. These results support the hypothesis that, in the Brazilian State of Sao Paulo, classical Hodgkin lymphoma has changed and now shows characteristics consistent with Pattern III observed in populations that experienced a similar socioeconomic transition.

To demonstrate that urine cytology screening can provide relevant epidemiological data for earlier detection of urothelial cancer caused by occupational exposure. Prospective cohort study. Industries using urothelial carcinogens in France. Urine samples were collected on site, after a work week and were analysed at the University Hospital of Clermont-Ferrand, France. Participants were workers exposed to urothelial carcinogens. Women and current smokers at time of study recruitment were exclusion criteria. Urine cells atypia were ranged into three classes: negative/normal, atypical/suspicious/dysplasia or positive/malignant. We included 2020 workers over a period of 20 years from 1993 to 2013: 606 worked in rubber manufacturing, 692 from metal processing, 245 in chemical industry and 477 in roadwork and building industry. Workers had a mean exposure of 15.2±10.4 years before their first urine cytology screening. There was a mean of 3.4±4.3 urine cytology screenings per worker between 1993 and 2013. 6478 cytology were normal, 462 suspicious and 13 malignant. Suspicious and malignant cytology occurred in 4.8% of workers exposed for 1-10 years, 6.2% for 11-20 years of exposure, 7.6% for 21-30 years and 8.6% for >30 years (p<0.001). Using exposure for 1-10 years as reference, the adjusted OR of receiving a suspicious or malignant diagnosis increased with duration of exposure: OR=1.50 (95% CI 1.10 to 2.05, p=0.01) for 21-30 years and OR=1.78 (95% CI 1.23 to 2.56, p=0.002) for >30 years of exposure. Using metal processing as reference, the risk of pathological urine cytology results increased for rubber manufacturing (OR=1.32, 95% CI 1.05 to 1.65, p=0.02), with a trend for roadwork and building industry (OR=1.39, 95% CI 0.98 to 1.97, p=0.07) and for chemical industry (OR=1.34, 95% CI 0.94 to 1.93, p=0.11). Urine cytology is a useful tool in occupational medicine. We promote new guidelines with an early screening of urothelial cancer by cytology, starting with

The purpose was to compare male and female police students exercise and physical performances at the beginning and the end of a 3-year police education. Two hundred thirty-five subjects answered the survey about exercise and 85 subjects (58 men: age = 23.7 ± 2.8 years, body mass = 82.1 ± 7.8 kg, height = 1.83 ± 0.06 m; 27 women: age = 24.9 ± 3.1 years, body mass = 66 ± 8.5 kg, height = 1.70 ± 0.09 m) participated in the 4 physical exercises (bench press, pull-ups, standing long jump, and 3,000-m run). It was found that the priority of maximum strength training increased (p < 0.001), whereas the priority of endurance and sprint training decreased during the 3-year period, with no differences between gender (p ≥ 0.28). The performances in the strength-related physical tests, bench press, and pull-ups also increased in the same period. These changes were the same for both genders. Findings showed a discrepancy between what is reported as necessary physical skills in police work and what actually is trained during the police education. This discrepancy was caused by the large focus upon maximal strength in the physical examination program in the police education.

Infrared Spectroscopy of Symbiotic Stars. II. Orbits for Five S-Type Systems with Two-Year Periods

2000-12-01

Infrared radial velocities have been used to determine orbital elements for the cool giants of five well-known symbiotic systems, Z And, AG Dra, V443 Her, AX Per, and FG Ser, all of which have orbital periods near the two-year mean period for S-type symbiotics. The new orbits are in general agreement with previous orbits derived from optical velocities. From the combined optical and infrared velocities, improved orbital elements for the five systems have been determined. Each of the orbital periods has been determined solely from the radial-velocity data. The orbits are circular and have quite small mass functions of 0.001-0.03 Msolar. The infrared velocities of AG Dra do not show the large orbital velocity residuals found for its optical radial velocities.

The Early Start Denver Model (ESDM) is an intervention program recommended for pre-schoolers with autism ages 12-48 months. The rationale for this recommendation is the potential for intervention to affect developmental trajectories during early sensitive periods. We investigated outcomes of 32 children aged 18-48 months and 28 children aged 48-62 months receiving the ESDM for one year (approximately 20 h per week). Younger children achieved superior verbal DQ gains compared to their older counterparts. There were no group differences with respect to non-verbal DQ and adaptive behavior (with both age-groups undergoing significant change), or ASD severity (with neither age-group showing improvements on the ADOS). The association between verbal DQ gains and age at intake was moderated by baseline verbal level.

Studying the start of the Maunder Minimum to understand the current situation

2016-04-01

To investigate whether we now enter a Maunder-like grand minimum, we have to compare the current situation with the time around the start of the Maunder minimum. Sunspot observations in the 1610s are of particular importance and relevance, because they are shortly before the start of the Maunder Grand Minimum. While the Maunder Minimum it is usually dated from 1645 to 1715, Vaquero & Trigo (2015) argue that what they call the "Extended Maunder Minimum" would have started in 1618 during or around a Schwabe cycle minimum around that time. We have therefore studied the sunspot record of that time in detail. Hoyt & Schatten (1998) compiled for all known telescopic observers a list of their observations; recent solar activity studies for the past four centuries are based on their compilation. In addition to 12 observers listed by Hoyt & Schatten (1998) for the 1610s, we list six more observers with datable spot observations. Furthermore, while Hoyt & Schatten (1998) argue that Simon Marius would have observed from mid 1617 to the end of 1618 almost every day, but would have never seen a spot, we can show with the original reports by Marius that he observed from Aug 1611 to spring 1619 with a lot of sunspot detections. Similar, while Hoyt & Schatten (1998) argue that Giovanni Riccioli would have observed on almost every day in 1618, but would have never seen a spot, he did not report any own observations at all that year, but quoted Argoli for that there were no spots during the periods with comets in 1618. The data base by Hoyt & Schatten (1998) has several more errors in the 1610s, as we show also for the observations by Harriot, Scheiner, Malapert, Saxonius, and Tarde. We also compare drawings from Jungius with the observations by Harriot, Galilei, and Marius. In contrast to what is specified in Hoyt & Schatten (1998), after Harriot, the two Fabricius (father and son), Scheiner and Cysat, Marius and Schmidnerus are among the earliest datable telescopic sunspot

Case Study: Body Composition Periodization in an Olympic-Level Female Middle-Distance Runner Over a 9-Year Career.

Stellingwerff, Trent

2018-05-25

This case study features an Olympic-level female middle-distance runner implementing a science-based approach to body composition periodization. Data are emerging to suggest that it is not sustainable from a health and/or performance perspective to be at peak body composition year-round, so body composition needs to be strategically periodized. Anthropometric (n = 44), hematological, other health measures, and 1,500-m race performances (n = 83) were periodically assessed throughout a 9-year career. General preparation phase (September to April) featured the athlete at ∼2-4% over ideal competition phase body weight (BW) and body fat (%), with optimal energy availability being prioritized. The competition body composition optimization phase (May to August) included creating an individualized time frame and caloric deficit with various feedback metrics (BW, performance, and hunger) to guide the process. There were significant seasonal fluctuations in anthropometric outcomes between phases (47.3 ± 0.8 vs. 48.3 ± 0.9 kg BW; 53.6 ± 7.8 vs. 61.6 ± 9.7 mm International Society for the Advancement of Kinanthropometry sum of 8 [So8] skinfolds; p < .01), and a significant correlation of decreasing So8 during the peak competition period over her career (r = -.838; p = .018). The range of body composition during the competition period was 46.0-48.0 kg BW and a So8 range was 42.0-55.9 mm. There were also significant positive correlations between slower 1,500-m race times and increasing So8 (r = .437; p < .01), estimated fat mass (r = .445; p < .01), and BW (r = .511; p < .0001). The athlete only had two career injuries. This case study demonstrates a body composition periodization approach that allowed for targeted peak yearly performances, which improved throughout her career, while maximizing training adaptation and long-term athlete health through optimal energy availability.

Salinas Solé, Celia; Peña Angulo, Dhais; Gonzalez Hidalgo, Jose Carlos; Brunetti, Michele

2017-04-01

In this poster we applied the moving window approach (see Poster I of this collection) to analyze trends of summer and its corresponding months (June, July, August) temperature mean values of maximum (Tmax) and minimum (Tmin) in Spanish mainland to detect the effects of length period and starting year. Monthly series belong to Monthly Temperature dataset of Spanish mainland (MOTEDAS). Database contains in its grid format of 5236 pixels of monthly series (10x10 km). The threshold used in spatial analyses considers 20% of land under significant trend (p<0.05). The most striking results are as follow: • Tmax and Tmin seasonal trends affected mostly all the Spanish mainland, while the area affected decrease from 1983-2010 (Tmax) and 1987-2010 (Tmin). In both cases the areas affected significantly in recent decades are restricted to Eastern-coastland areas. • Monthly analyses show highly differences between Tmax and Tmin. Only June Tmax show significant trend in extended areas, and in fact from 70´s they are restricted to eastern coastland. Meanwhile both July and August Tmax trend affect particularly that area until mid 70´s. • Monthly trend analyses of Tmin show different patterns both in temporal windows and spatial distribution. Significant trend in June dominates practically all windows, while in July and August they predominate in south and eastern-Mediterranean coastland. No significant trend has been observed from middle of the 80´s (< 20% of area). In conclusion, summer trend analyses of Tmax and Tmin and their spatial distribution show clearly highly differences. In Tmax seasonal trend seems to be dominated by June Tmax behavior, while in Tmin the contribution of July and August must be considered particularly in southern and eastern-Mediterranean coastland. The most recent decades in Tmax and Tmin do not show significance, except in June Tmin.

Return period estimates for European windstorm clusters: a multi-model perspective

NASA Astrophysics Data System (ADS)

Renggli, Dominik; Zimmerli, Peter

2017-04-01

Clusters of storms over Europe can lead to very large aggregated losses. Realistic return period estimates for such cluster are therefore of vital interest to the (re)insurance industry. Such return period estimates are usually derived from historical storm activity statistics of the last 30 to 40 years. However, climate models provide an alternative source, potentially representing thousands of simulated storm seasons. In this study, we made use of decadal hindcast data from eight different climate models in the CMIP5 archive. We used an objective tracking algorithm to identify individual windstorms in the climate model data. The algorithm also computes a (population density weighted) Storm Severity Index (SSI) for each of the identified storms (both on a continental and more regional basis). We derived return period estimates for the cluster seasons 1990, 1999, 2013/2014 and 1884 in the following way: For each climate model, we extracted two different exceedance frequency curves. The first describes the exceedance frequency (or the return period as the inverse of it) of a given SSI level due to an individual storm occurrence. The second describes the exceedance frequency of the seasonally aggregated SSI level (i.e. the sum of the SSI values of all storms in a given season). Starting from appropriate return period assumptions for each individual storm of a historical cluster (e.g. Anatol, Lothar and Martin in 1999) and using the first curve, we extracted the SSI levels at the corresponding return periods. Summing these SSI values results in the seasonally aggregated SSI value. Combining this with the second (aggregated) exceedance frequency curve results in return period estimate of the historical cluster season. Since we do this for each model separately, we obtain eight different return period estimates for each historical cluster. In this way, we obtained the following return period estimates: 50 to 80 years for the 1990 season, 20 to 45 years for the 1999

The decomposition products of pulse-periodic discharge atmospheric pressure plasma in apokamp, diffuse and corona modes were determined by optical and chemical methods. It is shown that apokamp discharge formation starts at a critical value of dissipation power in a discharge channel. Simultaneously, due to the thermochemical reactions, plasma starts to efficiently produce nitrogen oxides.

We describe the progression of cognitive decline and identify the predictive values of cognitive tests in three groups of REM sleep behavior disorder (RBD) patients classified at their last follow-up as having Parkinson's disease (PD), dementia with Lewy bodies (DLB), or still-idiopathic. Patients (n = 109) underwent polysomnographic, neurological, and neuropsychological assessments. We used linear mixed-model analyses to compare the progression of cognitive test performance between the three groups over a 3-year prodromal period, and performed linear regressions for a 6-year prodromal period. We compared the proportions of patients with clinically impaired performance (z scores < -1.5). DLB patients were pair-matched according to age, sex, and education to healthy controls (2:1 ratio), and receiver operating characteristic curves were performed to identify the psychometric properties of cognitive tests to predict dementia. At follow-up, 38 patients (35%) developed a neurodegenerative disorder: 20 had PD and 18 DLB. Cognitive performance changes over time were strongly associated with later development of dementia. Clear deficits in attention and executive functions were observed 6 years before diagnosis. Verbal episodic learning and memory deficits started later, deviating from normal approximately 5 to 6 years and becoming clinically impaired at 1 to 2 years before diagnosis. Visuospatial abilities progressed variably, with inconsistent prodromal latencies. The Trail Making Test (part B), Verbal Fluency (semantic), and Rey Auditory-Verbal Learning Test (total, immediate, and delayed recalls) were the best predictors for dementia (area under the curve = 0.90-0.97). Prodromal DLB is detectible up to 6 years before onset. For clinical utility, the Trail Making Test (part B) best detects early prodromal dementia stages, whereas Verbal Fluency (semantic) and verbal episodic learning tests are best for monitoring changes over time.

Climate change is one of the most important environmental challenges in the world and forest as a dynamic phenomenon is influenced by environmental changes. The Hyrcanian forests is a unique natural heritage of global importance and we need monitoring this region. The objective of this study was to detect start and end of season trends in Hyrcanian forests of Iran based on biweekly GIMMS (Global Inventory Modeling and Mapping Studies) NDVI3g in the period 1981-2012. In order to find response of vegetation activity to local temperature variations, we used air temperature provided from I.R. Iran Meteorological Organization (IRIMO). At the first step in order to remove the existing gap from the original time series, the iterative Interpolation for Data Reconstruction (IDR) model was applied to GIMMS and temperature dataset. Then we applied significant Mann Kendall test to determine significant trend for each pixel of GIMMS and temperature datasets over the Hyrcanian forests. The results demonstrated that start and end of season (SOS & EOS respectively) derived from GIMMS3g NDVI time series increased by -0.16 and +0.41 days per year respectively. The trends derived from temperature time series indicated increasing trend in the whole of this region. Results of this study showed that global warming and its effect on growth and photosynthetic activity can increased the vegetation activity in our study area. Otherwise extension of the growing season, including an earlier start of the growing season, later autumn and higher rate of production increased NDVI value during the study period.

Propolis has been used as a natural health product mainly due to the presence of polyphenols, flavonoids, phenolic aldehydes, amino acids, vitamins and others bioactive constituents. To this natural substance are attributed different biological and pharmacological properties which are influenced by its chemical composition and organoleptic properties. The aim of this work was to evaluate the physicochemical properties and parameters of green propolis collected during a period of six years (2008-2013) in the state of Minas Gerais, located at the southeastern region of Brazil. The methodology were in accordance with Brazilian legislation on the identity and quality standards of propolis. The evaluated parameters of hydroalcoholic from green propolis were total flavonoids, antioxidant activity - DPPH method, oxidation index, wax content, humidity and insoluble impurities. Propolis samples collected in different seasons during the years 2008 to 2013 presented mean values of total flavonoids (3.4 ± 0.11 mg/g), antioxidant activity DPPH (4.76 ± 0.16 μg/mL), oxidation index (3, 4 ± 0.33 seconds) and wax (15.14 ± 0.78% m/m), which are in accordance with Brazilian legislation. Green propolis did not show abrupt seasonal changes during the six years of investigation, and may be considered as an adequate functional ingredient.

Although HIV disease stage at ART initiation critically determines ART outcomes, few reports have longitudinally monitored this within Asia. Using prospectively collected data from a large ART program at Sihanouk Hospital Center of Hope in Cambodia, we report on the change in patient characteristics and outcomes over a ten-year period. We conducted a retrospective analysis including all adults (≥ 18 years old) starting ART from March 2003-March 2013 in a non-governmental hospital in Phnom Penh, Cambodia. The cumulative incidence of death, lost to follow-up (LTFU), attrition (death or LTFU) and first line treatment failure were calculated using Kaplan-Meier methods. Independent risk factors for these outcomes were determined using Cox regression modeling. Over the ten-year period, 3581 patients initiated ART with a median follow-up time of 4.8 years (IQR 2.8-7.2). The median age was 35 years (IQR 30-41), 54% were female. The median CD4 count at ART initiation increased from 22 cells/μL (IQR 4-129) in 2003 to 218 (IQR 57-302) in 2013. Over the 10 year period, a total of 282 (7.9%) individuals died and 433 (12.1%) were defined LTFU. Program attrition (died or LTFU) was 11.1% (95% CI: 10.1%- 12.4%) at one year, 16.3% (95% CI: 15.1%-17.6%) at three years, 19.8% (95% CI: 18.5%-21.2%) at five years and 23.3% (95% CI: 21.6-25.1) at ten years. Male sex and low baseline body mass index (BMI) were associated with increased attrition. Factors independently associated with mortality included a low baseline CD4 count, older age, male sex, low baseline BMI and hepatitis B co-infection. Individuals aged above 40 years old had an increased risk of mortality but were less likely to LTFU. There were a total of 137 individuals with first line ART failure starting second line treatment. The probability of first line failure was estimated at 2.8% (95% CI: 2.3%-3.4%) at 3 years, 4.6% (95% CI: 3.9%-5.5%) at 5 years and 7.8% (95% CI 4.8%-12.5%) at ten years of ART. The probability was

Global Snow-Cover Evolution from Twenty Years of Satellite Passive Microwave Data

Starting in 1979 with the SMMR (Scanning Multichannel Microwave Radiometer) instrument onboard the satellite NIMBUS-7 and continuing since 1987 with the SSMI (Special Sensor Microwave Imager) instrument on board the DMSP (Defence Meteorological Satellite Program) series, more then twenty years of satellite passive microwave data are now available. This dataset has been processed to analyse the evolution of the global snow cover. This work is part of the AICSEX project from the 5th Framework Programme of the European Community. The spatio-temporal evolution of the satellite-derived yearly snow maximum extent and the timing of the spring snow melt were estimated and analysed over the Northern Hemisphere. Significant differences between the evolution of the yearly maximum snow extent in Eurasia and in North America were found. A positive correlation between the maximum yearly snow cover extent and the ENSO index was obtained. High interannual spatio-temporal variability characterises the timing of snow melt in the spring. Twenty-year trends in the timing of spring snow melt have been computed and compared with spring air temperature trends for the same period and the same area. In most parts of Eurasia and in the central and western parts of North America the tendency has been for earlier snow melt. In northeastern Canada, a large area of positive trends, where snow melt timing starts later than in the early 1980s, corresponds to a region of positive trends of spring air temperature observed over the same period.

The board of the Dutch Paediatric Association requested a survey of the scientific research performed in all academic and non-academic paediatric hospitals, authorized to train medical doctors in paediatrics in the Netherlands. Contributions to the international and the Dutch scientific literature, in the form of regular publications, chapters in books, contributions to proceedings and Ph.D. theses were counted over two 5-year periods, i.e. 1981-1985 and 1986-1990. The quality of publications in the international journals was assessed using the average impact factor of the journals over the 10-year period. The number of publications in the international literature doubled during the observation period 1986-1990 compared to the period 1981-1985. Nevertheless, the quality of the publications remained the same. Metabolism, oncology/haematology, immunology/infectious diseases and cardiology are the subspecializations in which scientific research takes place in four or more academic paediatric hospitals. In total, 84 Ph.D. theses were produced in which a paediatrician was either the project leader (mostly a professor in paediatrics) or the investigator-in-charge. Insight into structure and major research efforts of paediatric hospitals in other countries of Europe may lead to exchange of views and, maybe, profitable co-operation.

Obesity is currently considered to be the most frequent metabolic disease worldwide, not only in developed but also in developing countries. The aim of this work was to describe the development of health status in soldiers of the Armed Forces of the Czech Republic (ACR) and to emphasizethe markers of non-communicable diseases. Our study describes the anthropometric and biochemical parameters of a large group of Czech Army professional soldiers. Data were obtained over a period of 11 years. During the monitored period, from 1999 to 2009, military physicians carried out on the average 6,360 examinations on professional soldiers per year and monitored their health and nutritional status with the aim of preventing the risk factors of non-communicable diseases. These examinations are compulsory for all professional soldiers at the age of 25, 30, 33, and 36 years. From the age of 39, these examinations are carried out every year till the end of their career. Besides taking personal histories and carrying out standard physical examinations, blood was taken for biochemical examination. The following anthropometric parameters were monitored: body constitution using body mass index (BMI) and waist circumference. Our study describes only part of the data concerning anthropometric and biochemical parameters of professional soldiers which were obtained over a period of 11 years. Average BMI values in men were in the overweight range (26.5-27 kg/m2). Average values of waist circumference, however, ranged from 91.9 cm to 93.4 cm. Between the first and the last year of monitoring a statistically significant decrease in these values ranging from 93.4 ± 9.8 cm to 92.7 ± 9.5 cm (p < 0.001) was observed. All monitored anthropometric parameters in female professional soldiers were within normal limits. During the monitored period the proportion of overweight men gradually increased from 52% to 57.1% (p < 0.001). There were no statistically significant changes in the prevalence of

Pakistan/USAID to start CSM project.

PubMed

1984-01-01

Pakistan, with the assistance of funds for the US Agency for International Development (USAID), is about to start its novel approach to contraceptive social marketing (CSM). This new effort suggests a marked policy shift on the part of the Pakistan government toward intensifying its family planning activities. The program will be government-operated and supported by AID over the next 5 years with $20 million, more than double the cost of similar CSM projects elswhere. Distribution of a condom on a pilot project basis is expected to begin by December 1984. Sales of a low-dose oral contraceptive (OC) could begin in test market areas by mid-1985, with national launching of both products tentatively scheduled for January 1986. The Pakistan/USAID agreement represents the 1st time since the formation of India's Nirodh project in the late 1960s that a CSM program is being established without the involvement of either an international social marketing contractor or a country's family planning association. The Pakistan CSM program will be managed by a policy board composed of representatives from the government's Ministries of Planning, Health and Education; a resident advisor from USAID; and a local company responsible for product marketing and distribution. The approach has received a skeptical response among international social marketing experts about the program's chances for success. Their doubts extend to 2 other aspects of the proposed design: an official of the Ministry of Planning's Population and Welfare Division expects the CSM program to generate sufficient revenues to cover all operating costs following the 5-year subsidy period, while also providing attractive profit margins for the marketing/distribution company; and the government prohibits mass media advertising of contraceptives. According to AID, the issue of mass media contraceptive advertising has not yet been resolved, and a national survey will be conducted to determine what communication needs are

We construct a visual light curve of the symbiotic star MWC covering the last 87 years of its history. The data were assembled from the literature and from the AAVSO data bank. Most of the periodic components of the system brightness variation can be accounted for by the operation of three basic clocks of the periods P1 = 19,000 days, P2 = 1943 days, and P3 = 722 days. These periods can plausibly, and consistently with the observations, be attributed to three physical mechanisms in the system: the working of a solar-like magnetic dynamo cycle in the outer layers ofmore » the giant star of the system, the binary orbit cycle, and the sidereal rotation cycle of the giant star. MWC 560 is the seventh symbiotic star with historical light curves that reveal similar basic characteristics of the systems. The light curves of all these stars are well interpreted on the basis of the current understanding of the physical processes that are the major sources of the optical luminosity of these symbiotic systems.« less

To investigate parental knowledge about adolescent sleep needs, and other beliefs that may inform their support for or objection to later school start times. In 2014, we conducted a cross-sectional, Internet-based survey of a nationally representative sample of parents as part of the C.S. Mott Children's Hospital National Poll on Children's Health. Parents with teens aged 13-17 years reported their children's sleep patterns and school schedules, and whether the parents supported later school start times (8:30 am or later). Responses associated with parental support of later school start times were examined with logistic regression analysis. Overall, 88% of parents reported school start times before 8:30 am, and served as the analysis sample (n = 554). In this group, 51% expressed support for later school start times. Support was associated with current school start times before 7:30 am (odds ratio [OR] = 3.1 [95% confidence interval (CI) 1.2, 8.4]); parental opinion that their teen's current school start time was "too early" (OR = 3.8 [1.8, 7.8]); and agreement with American Academy of Pediatrics recommendations about school start times (OR = 4.7 [2.2, 10.1]). Support also was associated with anticipation of improved school performance (OR = 3.0 [1.5, 5.9]) or increased sleep duration (OR = 4.0 [1.8, 8.9]) with later school start times. Conversely, parents who anticipated too little time for after-school activities (OR = 0.5 [0.3, 0.9]) and need for different transportation plans (OR = 0.5 [0.2, 0.9]) were often less supportive. Parental education about healthy sleep needs and anticipated health benefits may increase their support for later school start times. Educational efforts should also publicize the positive experiences of communities that have made this transition, with regard to limited adverse effect on after-school activity schedules and transportation. © 2017 American Academy of Sleep Medicine

With the onset of adolescence, teenagers require 9.2 hr of sleep and experience a delay in the timing of sleep. In the "real world" with early school start times, however, they report less sleep, striking differences between their school-weekend sleep schedules, and significant daytime sleepiness. Prior studies demonstrated that high schoolers with later school starts do not further delay bedtime but obtain more sleep due to later wake times. This study examined sleep-wake patterns of young adolescents attending urban, public middle schools with early (7:15 a.m.) versus late (8:37 a.m.) start times. Students (N = 205) were assessed at 2 time periods. Students at the late-starting school reported waking up over 1 hr later on school mornings and obtaining 50 min more sleep each night, less sleepiness, and fewer tardies than students at the early school. All students reported similar school-night bedtime, sleep hygiene practices, and weekend sleep schedules.

Overweight and obesity are prevalent among young women and are greater among minority and low-income women. The postpartum period is critical in women's weight trajectories as many women do not lose their pregnancy weight, and others lose some and then plateau or experience weight gain. Excess weight puts women at greater risk of chronic disease and thus weight loss in the postpartum period may be key to the long-term health of young women. This paper describes the design and methods of a randomized clinical trial of Fresh Start, an innovative narrative-based group intervention aimed at promoting postpartum weight loss among low-income, diverse women. Study participants were recruited from the five sites of the Women, Infants and Children (WIC) program in central Massachusetts. Participants were English-speaking, age ≥ 18 years, 6 weeks to 6 months postpartum, with a body mass index (BMI) ≥ 27 kg/m(2). The Fresh Start postpartum weight loss intervention, adapted from the Diabetes Prevention Program (DPP) in collaboration with WIC staff and clients, consisted of an 8-week group-based curriculum followed by nine monthly telephone calls. It included a narrative component (i.e., storytelling), group discussions, print materials and access to exercise facilities. The study is a two-arm randomized controlled trial. The control condition included print materials and access to exercise facilities. In-person assessments were conducted at baseline and at 6 and 12 months following the eight-week intervention phase. The Fresh Start intervention translated key elements of an evidence-based weight loss protocol into a format that is hypothesized to be relevant, acceptable and effective for the target audience of low-SES postpartum women. This novel intervention was developed in collaboration with WIC to be sustainable within the context of its clinics, which reach approximately 9 million individuals per year across the U.S. via 10,000 clinics. clinicaltrials

Pulmonary arterial hypertension (PAH) is characterized by increased pulmonary vascular resistance, right ventricular dysfunction and death. Despite scientific advances, is still associated with high morbidity and mortality. The aim is to describe the clinical approach and determine the prognostic factors of patients with PAH treated in a national reference center over 30 years. Three hundred and seventy nine consecutive patients with PAH (January 1984 to December 2014) were studied. Were divided into 3 periods of time: before 2004, 2004-2009 and 2010-2014. Prognostic factors (multivariate analysis) were analyzed for clinical deterioration. Median age was 44 years (68.6% women), functional class III-IV: 72%. An increase was observed in more complex etiologies in the last period of time: Pulmonary venooclusive disease and portopulmonary hypertension. Upfront combination therapy significantly increased (5% before 2004 vs 27% after 2010; P < .05). Multivariate analysis showed prognostic significance in age, sex, etiology and combined clinical variables as they are independent predictors of clinical deterioration (P < .05). Survival free from death or transplantation for the 1st, 3rd and 5th year was 92.2%, 80.6% and 68.5% respectively. The median survival was 9 years (95% confidence interval, 7.532-11.959) CONCLUSIONS: The PAH is a heterogeneous and complex disease, the median survival free from death or transplantation in our series is 9 years after diagnosis. The structure of a multidisciplinary unit PAH must adapt quickly to changes that occur over time incorporating new diagnostic and therapeutic techniques.

Background Glyphosate is a herbicide that is liable to be used in the extensive cultivation of glyphosate-tolerant cultivars. The potential accumulation of the relative effect of glyphosate on the rhizobacterial communities of glyphosate-tolerant maize has been monitored over a period of three years. Methodology/Principal Findings The composition of rhizobacterial communities is known to vary with soil texture, hence, the analyses have been performed in two agricultural fields with a different soil texture. The accumulative effects of glyphosate have been monitored by means of high throughput DNA pyrosequencing of the bacterial DNA coding for the 16S rRNA hypervariable V6 region from rhizobacterial communities. The relative composition of the rhizobacterial communities does vary in each field over the three-year period. The overall distribution of the bacterial phyla seems to change from one year to the next similarly in the untreated and glyphosate-treated soils in both fields. The two methods used to estimate bacterial diversity offered consistent results and are equally suitable for diversity assessment. Conclusions/Significance The glyphosate treatment during the three-year period of seasonal cultivation in two different fields did not seem to significantly change the maize rhizobacterial communities when compared to those of the untreated soil. This may be particularly relevant with respect to a potential authorisation to cultivate glyphosate-tolerant maize in the European Union. PMID:22096595

Dissemination of periodic mammography and patterns of use, by birth cohort, in Catalonia (Spain)

Background In Catalonia (Spain) breast cancer mortality has declined since the beginning of the 1990s. The dissemination of early detection by mammography and the introduction of adjuvant treatments are among the possible causes of this decrease, and both were almost coincident in time. Thus, understanding how these procedures were incorporated into use in the general population and in women diagnosed with breast cancer is very important for assessing their contribution to the reduction in breast cancer mortality. In this work we have modeled the dissemination of periodic mammography and described repeat mammography behavior in Catalonia from 1975 to 2006. Methods Cross-sectional data from three Catalan Health Surveys for the calendar years 1994, 2002 and 2006 was used. The dissemination of mammography by birth cohort was modeled using a mixed effects model and repeat mammography behavior was described by age and survey year. Results For women born from 1938 to 1952, mammography clearly had a period effect, meaning that they started to have periodic mammograms at the same calendar years but at different ages. The age at which approximately 50% of the women were receiving periodic mammograms went from 57.8 years of age for women born in 1938–1942 to 37.3 years of age for women born in 1963–1967. Women in all age groups experienced an increase in periodic mammography use over time, although women in the 50–69 age group have experienced the highest increase. Currently, the target population of the Catalan Breast Cancer Screening Program, 50–69 years of age, is the group that self-reports the highest utilization of periodic mammograms, followed by the 40–49 age group. A higher proportion of women of all age groups have annual mammograms rather than biennial or irregular ones. Conclusion Mammography in Catalonia became more widely implemented during the 1990s. We estimated when cohorts initiated periodic mammograms and how frequently women are receiving them

This study was designed to determine the susceptibility of clinical isolates of multidrug-resistant (MDR) and non-MDR Mycobacterium tuberculosis to sulfamethoxazole, trimethoprim and trimethoprim/sulfamethoxazole over a 12 year period in Taiwan. We examined a total of 117 clinical isolates of M. tuberculosis collected from Southern Taiwan, 116 from 1995 to 2006 and an extensively drug-resistant (XDR) isolate in 2009. These included 28 isolates susceptible to all four first-line agents, 52 MDR isolates and 36 isolates with a mixed combination of drug resistance patterns other than MDR and 1 XDR isolate. Sulfamethoxazole inhibited 80% growth of all 117 isolates regardless of their susceptibility to the first-line agents at an MIC(90) of 9.5 mg/L. The concentration required to inhibit 99% growth was 38 mg/L. There were no significant changes in the MIC(50) or MIC(90) of sulfamethoxazole over a 12 year period. All 117 isolates were resistant to trimethoprim at >8 mg/L. The combination of trimethoprim/sulfamethoxazole at a ratio of 1:19 had no additive or synergistic effects. Sulfamethoxazole inhibited the growth of clinical isolates of M. tuberculosis at achievable concentrations in plasma after oral administration. Susceptibility to sulfamethoxazole remained constant over a 12 year period. Trimethoprim was inactive against M. tuberculosis and trimethoprim/sulfamethoxazole provided no additional activity. Although the current and prior studies demonstrate that sulfamethoxazole is active against M. tuberculosis the search needs to continue for more active, lipid-soluble sulphonamides that are better absorbed into tissues and have improved therapeutic efficacy.

To determine the characteristics and trends of medical emergencies during school activities by analyzing information provided by fire departments. During a 5-year period from January 2009 to December 2013, all nine fire departments in Fukui Prefecture handled 850 emergencies at schools. We investigated the 850 cases with the age range of 0-63 years. It was found that 21.5% of ambulance dispatches to schools were on weekends and there were more dispatches for non-faculty members of all age groups on weekends than on weekdays. The percentage of weekend dispatches was particularly high for students aged ≥19 years. Emergency calls for junior high school students and younger students accounted for the majority of weekday calls. There were a total of 524 ambulance dispatches for the three categories "sprains, contusions, dislocations, and fractures" ( n = 245), "seizures, epilepsy, and syncope" ( n = 171), and "cuts, bruises, lacerations, trauma, amputations, and burns" ( n = 108), with dispatches for these three categories accounting for 61.6% of all dispatches. Almost all dispatches for "heat stroke and dehydration" were during school hours and were concentrated between the months of July and September. Heat stroke was most common among high school students and most often occurred during the summer/fall season and on weekends. Heat stroke was the fourth most frequent condition that required an ambulance dispatch after the above three conditions. Heat stroke is predictable, indicating that it is necessary to prevent heat stroke during high school club activities.

Rational prescribing in older people is a priority for health care organizations. The STOPP/START screening tool has been developed to identify potentially inappropriate prescribing (PIP) in individuals. In a primary care setting, STOPP/START can estimate PIP prevalence and related factors at population level. The aim of this study is to measure the prevalence rates of PPI in elderly population using clinical and prescription claim databases. Cross-sectional population study. Primary Care, Lleida Health Region, Spain. 45.408 patients 70 years old and over, attended in the primary health care centers at least once the last year. 43 STOPP and 12 START criteria are applied to their 2012 clinical and prescription records. Logistic regression models are adjusted to determine PIP association with several factors. 45,408 patients are included. The mean age is 79.7 years, 58% being female. The overall prevalence of PPI is 58.1%. According to STOPP, the most common drugs identified are benzodiazepines, non-steroidal anti-inflammatory drugs and proton pump inhibitors; according to START, osteoporosis treatments, antiplatelet agents, statins, metformin and beta blockers. PIP increases with age and polypharmacy and it is higher in long-term care facilities residents and patients receiving home health care. In our Health Region, at least 50% of the population aged 70 or older has one or more PIP, according to STOPP/START criteria. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

The Health Post of Corte de Pedra is located in a region endemic for American tegumentary leishmaniasis (ATL) in the Brazilian state of Bahia, and it treats 500–1,300 patients annually. To describe temporal changes in the epidemiology of ATL, we reviewed a random sample of 10% of patient charts (N = 1,209) from 1988 to 2008. There was a twofold increase in the number of cases over the 20-year period, with fluctuations in 10-year cycles. Patients were most frequently male, between the ages of 10 and 30 years, and engaged in agricultural labor; 4.3% of patients had mucosal disease, and 2.4% of patients had disseminated disease. Over the study period, the number of disseminated cases increased threefold, the proportion of cases in younger patients and agricultural workers decreased, and the proportion of patients residing in coastal areas increased. ATL is on the rise in Bahia, with a 10-year periodicity and evolving changes in epidemiology and manifestations of disease. PMID:22403312

Success of Urgent-Start Peritoneal Dialysis in a Large Canadian Renal Program

♦ Background: Many patients start renal replacement therapy urgently on in-center hemodialysis via a central venous catheter, which is considered suboptimal. An alternative approach to manage these patients is to start them on peritoneal dialysis (PD). In this report, we describe the first reported Canadian experience with an urgent-start PD program. Additionally we reviewed the literature in this area. ♦ Methods: In this prospective observational study, we report on our experience in a single academic center. This program started in July 2010. We included patients who initiated PD urgently, that is within 2 weeks of catheter insertion. We followed all incident PD patients until October 2013 for mechanical and infectious complications. Peritoneal dialysis catheters were inserted either percutaneously or laparoscopically and dialysis was initiated in either an inpatient or outpatient setting. ♦ Results: Thirty patients were started on urgent PD during our study period. Follow-up ranged from 28 to 1,050 days. Twenty insertions (66.7 %) were done percutaneously and 10 (33.3%) were laparoscopic. Dialysis was initiated within 2 weeks (range: 0 – 13 days, median = 6 days). Twenty-four patients (80%) started PD in an outpatient setting and 6 patients (20%) required immediate inpatient PD start. Three patients (10%) developed a minor peri-catheter leak during the first week of training that was managed conservatively. There were no episodes of peritonitis or exit-site/tunnel infection during the first 4 weeks post-insertion. Four patients (13.3 %) from the percutaneous insertion group and 2 patients (6.7%) from laparoscopic insertions developed catheter dysfunction due to migration, which was managed by repositioning, without need for catheter replacement or modality switch. ♦ Conclusions: Our results are consistent with other studies in this area and demonstrate that urgent-start PD is an acceptable and safe alternative to hemodialysis in patients who need to

Prior studies have confirmed that commercial airline pilots experience circadian phase shifts and short sleep duration following travel with layovers in different time zones. Few studies have examined the impact of early and late starts on the sleep and circadian phase of airline pilots who return to their domicile after each duty period. We recruited 44 pilots (4 female) from a short-haul commercial airline to participate in a study examining sleep and circadian phase over four duty schedules (baseline, early starts, mid-day starts, late starts). Each duty schedule was five days long, separated by three rest days. Participants completed the rosters in the same order. Sleep outcomes were estimated using wrist-borne actigraphy (Actiware Software, Respironics, Bend, OR) and daily sleep diaries. Thirteen participants volunteered to collect urine samples for the assessment of 6-sulfatoxymelatonin (aMT6s). Urine samples were collected in four-hourly bins during the day and eight-hourly bins during sleep episodes, for 24 hours immediately following each experimental duty schedule. The aMT6s results were fit to a cosine in order to obtain the acrophase to estimate circadian phase. Univariate statistics were calculated for acrophase changes, schedule start times and sleep times. All statistical analyses were computed using SAS software (Cary, IN).

Fragrances are widely encountered in our daily environment and are known to be a common cause of allergic contact dermatitis. We have reviewed our patch test data from 1980 to 1996 to establish whether the pattern of fragrance allergy has changed with time. During this period, 25,545 patients (10,450 male, 15,005 female) were patch tested with the European standard series. The mean annual frequency of positive reactions to the fragrance mix was 8.5% in females (range 6.1-10.9) and 6.7% in males (range 5.1-12.9). Females were 1.3 times more likely to be allergic to fragrance (P < 0.001, 95% confidence interval, CI 1.17-1.41). Males with fragrance allergy were older than females by 5.6 years (mean age 48.2 vs. 42.6 years; P < 0.001, 95% CI 3.9-7.3). The incidence of a concomitant positive patch test to balsam of Peru in fragrance-sensitive patients showed wide variation, suggesting that it is not a reliable marker of fragrance allergy. There was a positive correlation between the isomers isoeugenol and eugenol. Oak moss remained the most common overall allergen throughout the study, positive in 38.3% of females and 35.6% of males who were tested to the constituents of the fragrance mix. During the period of the study the incidence of positive tests to oak moss increased by 5% yearly (P = 0.001, 95% CI 2.2-8.7). The frequency of allergic reactions to eugenol and geraniol remained relatively constant. Isoeugenol and alpha-amyl cinnamic aldehyde sensitivity increased and hydroxycitronellal showed a slow decline. There was a striking reduction in the frequency of sensitivity to cinnamic aldehyde (by 18% yearly; P < 0.001, 95% CI 14.3-21.0) and cinnamic alcohol (by 9% yearly; P < 0.001, 95% CI 5.2-12.9); these are now uncommon fragrance allergens. These data show temporal trends which may reflect the frequency of population exposure to individual fragrances.

The number of scientific papers is a conventional metric for the measurement of a country's research performance in a particular area. To evaluate the trend in Iranian publications of dental research results in peer-reviewed international scientific journals over the period 1999-2009, using national and international databases, and to compare the results with other countries. The search process was performed by two independent persons in PubMed and Iranian Medline (IranMedex). Data extraction included the year of publication, total number of dental papers in each year, total number of Iranian dental papers in each year and number of papers with a high level of evidence; these were compared with those in other Asian countries. The total number of dental articles indexed in PubMed during the studied period was 207,689, with 671 being written by researchers who stated their affiliation as Iran. Although the proportion of Iranian dental articles to all published dental articles was 0.01% in 1990, this increased to 1.4% in 2009. Of all clinical trials indexed in PubMed from 1990 to 2009, only 0.62% had an author from Iran. The collaboration rate of authors ranged between 1 and 10. Turkey and Iran had a larger number of dental research publications compared with other Asian countries assessed in this study. During the last two decades, there has been a considerable increase in the number of dental papers by Iranian researchers indexed in the PubMed database. © 2012 FDI World Dental Federation.

[Factors related to the slowdown in the reduction of the tuberculosis incidence rate in Osaka City--structure of the high incidence rate of tuberculosis in Osaka City analyzed by administrative-ward group, five-year period and age group].

The tuberculosis incidence rate in Osaka City is the highest in Japan. We analyzed the incidence rate in Osaka City in five-year period from 1978 to 1997, namely, 1978-1982 (period I), 1983-1987 (period II), 1988-1992 (period III), and 1993-1997 (period IV). Until the first half of 1980, the tuberculosis incidence rate in Osaka City had been dropping every year, but the rate of decline has been slowed substantially or even stopped since 1983. The incidence rate ratio of Osaka City compared with the national rate was 2.0 to 2.3 from 1970 to 1975, but it has been increasing from 1983 and is now higher than 3. We divided 24 wards of Osaka City into five groups based on selected employment indicators of population 15 years of age and over of 1995 National Census. Group A consists of two wards characterized by extremely high unemployment rate, Group B of four wards by high unemployment rate and high rate of manufacturing workers, Group C of six wards by high rate of non-manufacturing workers (tertiary industry workers), Group D of five wards by high rate of manufacturing workers, and Group E of seven wards by residential areas. The incidence rate of Group A had been declining during periods I and II but started to rise after period III. The rates of Group B and C had been declining from period I to II but the decline slowed down substantially even for every age class in periods III and IV. The incidence rates of Groups D and E have been falling. The incidence rate of the 50-69 year-old age group has been increasing substantially. The proportion of newly registered patients in Group A to all patients of Osaka City increased from 25.2% in period I to 32.7% in period IV. The number of newly registered patients of the 40-69 age class in Group A accounted for 45.1% of that in Osaka City in period IV. The slowdown in the reduction of the tuberculosis incidence rate has occurred not in all, but in only a few wards and it is a typical phenomenon of the middle-aged in those

Traumatic episodes experienced during the genocide period in Rwanda influence life circumstances in young men and women 17 years later

PubMed Central

2013-01-01

Background During Rwanda’s genocide period in 1994, about 800,000 people were killed. People were murdered, raped and seriously injured. This retrospective study investigated prevalence and frequency of traumatic episodes and associated psychosocial effects in young adults in Rwanda over the lifetime, during the genocide period and in the past three years. Methods This is a cross-sectional population-based study conducted among men and women, aged 20 to 35 years, residing in the Southern province of Rwanda. The study population, randomly selected in a multi stage procedure, included 477 females and 440 males. Data collection was performed through individual interviewing with a structured questionnaire during the period December 2011- January 2012. The Harvard Trauma Questionnaire was used to assess traumatic episodes. All data was sex-disaggregated. Differences between groups were measured by chi square and Fischer’s exact test. Associations with socio-demographic and psychosocial factors were estimated by use of odds ratios with 95% confidence intervals in bi- and multivariate analyses. Results The participants in this study were 3 to 18 years of age in 1994, the year of the genocide. Our sample size was 917 participants, 440 men and 477 women. Women were to a higher extent exposed to traumatic episodes than men during their lifetime, 83.6% (n = 399) and 73.4% (n = 323), respectively. During the genocide period, 37.5% of the men/boys and 35.4% of the women/girls reported such episodes while in the past three years (2009-2011) 25.0% of the men and 23.1% of the women did. Women were more exposed to episodes related to physical and sexual violence, while men were exposed to imprisonment, kidnapping and mass killings. Victims of such violence during the genocide period were 17 years later less educated although married (men OR 1.47; 0.98-2.19; women OR 1.54; 1.03-2.30), without children (men OR 1.59; 1.08-2.36; women OR 1.86; 1.11-3.08) and living under extremely

Solenoid-free plasma start-up in spherical tokamaks

NASA Astrophysics Data System (ADS)

Raman, R.; Shevchenko, V. F.

2014-10-01

The central solenoid is an intrinsic part of all present-day tokamaks and most spherical tokamaks. The spherical torus (ST) confinement concept is projected to operate at high toroidal beta and at a high fraction of the non-inductive bootstrap current as required for an efficient reactor system. The use of a conventional solenoid in a ST-based fusion nuclear facility is generally believed to not be a possibility. Solenoid-free plasma start-up is therefore an area of extensive worldwide research activity. Solenoid-free plasma start-up is also relevant to steady-state tokamak operation, as the central transformer coil of a conventional aspect ratio tokamak reactor would be located in a high radiation environment but would be needed only during the initial discharge initiation and current ramp-up phases. Solenoid-free operation also provides greater flexibility in the selection of the aspect ratio and simplifies the reactor design. Plasma start-up methods based on induction from external poloidal field coils, helicity injection and radio frequency current drive have all made substantial progress towards meeting this important need for the ST. Some of these systems will now undergo the final stages of test in a new generation of large STs, which are scheduled to begin operations during the next two years. This paper reviews research to date on methods for inducing the initial start-up current in STs without reliance on the conventional central solenoid.

This study presents evidence pertinent to current debates about the lasting impacts of early childhood educational interventions and, specifically, Head Start. A group of students who were first studied to examine the immediate impacts of the Tulsa, Oklahoma, Community Action Project (CAP) Head Start program were followed-up in middle school, primarily as 8th graders. Using ordinary least squares and logistic regressions with a rich set of controls and propensity score weighting models to account for differential selection into Head Start, we compared students who had attended the CAP Head Start program and enrolled in the Tulsa Public Schools (TPS) as kindergarteners with children who also attended TPS kindergarten but had attended neither CAP Head Start nor the TPS pre-K program as 4-year-olds. CAP Head Start produced significant positive effects on achievement test scores in math and on both grade retention and chronic absenteeism for middle-school students as a whole; positive effects for girls on grade retention and chronic absenteeism; for white students on math test scores; for Hispanic students on math test scores and chronic absenteeism, and for students eligible for free lunches on math test scores, grade retention, and chronic absenteeism. We conclude that the Tulsa CAP Head Start program produced significant and consequential effects into the middle school years. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Folate depletion is associated with an increased risk of colorectal carcinogenesis. A temporal association between folic acid fortification of enriched cereal grains and an increase in the incidence of colorectal cancer in the USA and Canada has, however, been recently reported. To compare the rates of hospital discharges owing to colon cancer in Chile before and after the start of the mandatory flour fortification program with 220 microg of synthetic folic acid/100 g of wheat flour. Cancer and cardiovascular hospital discharge rates were compared using rate ratios between two study periods, 1992-1996, before folic acid fortification and 2001-2004, after the flour fortification with folic acid was established in the country. Standard errors of the log rate ratio to derive confidence intervals, and to test the null hypothesis of no difference, were calculated. The highest rate ratio between the two periods was for colon cancer in the group aged 45-64 years (rate ratio: 2.6, confidence interval: 99% 2.93-2.58) and in the 65-79 years (rate ratio: 2.9, confidence interval: 99% 3.25-2.86). Our data provide new evidence that a folate fortification program could be associated with an additional risk of colon cancer.

Parenting Gains in Head Start as a Function of Initial Parenting Skill

Ansari, Arya; Purtell, Kelly; Gershoff, Elizabeth T.

2016-01-01

Using data from the Head Start Impact Study (n = 3,696), this article examines whether one year of Head Start differentially benefited parents as a function of their initial parenting behaviors. Four outcomes are examined, namely parents’ rates of engaging in cognitive stimulation, reading to their child, and spanking, as well as their depressive symptoms. In general, most parents demonstrated improvements in their reading practices and cognitive stimulation, regardless of their parenting behaviors at baseline. However, depressive symptoms and spanking behavior showed improvements only among parents who began the Head Start program with the most depressive symptoms and the most frequent spanking, respectively. These findings suggest that treatment-induced changes in parenting can vary by parents’ incoming attributes and that heterogeneity of effects should be considered. Implications for Head Start and other parenting interventions are discussed. PMID:27818529

Different starter systems for jet engines are discussed: electric, cartridge, iso-propyl-nitrate, air, gas turbine, and hydraulic. The fuel system, ignition system, air flow control system, and actual starting mechanism of an air starter motor system are considered. The variation of engine parameters throughout a typical starting sequence are described, with reference to examples for an RB211-535 engine. Physical constraints on engine starting are considered: rotating stall, light up, the window between hang and stall, hang, compressor stall, and the effects of ambient conditions. The following are also discussed: contractual and airworthiness requirements; windmilling; inflight relighting; afterburning light up; combustion stability; and broken shafts. Graphics illustrating the above are presented.

2012-01-01

The study objectives are to describe child care type and quality experienced by developmentally at-risk children, examine quality differences between Head Start and non-Head Start settings, and identify factors associated with receiving higher-quality child care. Data are analyzed from the Early Childhood Longitudinal Survey, Birth Cohort, a prospective study of a nationally representative sample of US children born in 2001. The sample consisted of 7,500 children who were assessed at 48 months of age. The outcome of interest is child care quality, measured by the Early Childhood Environmental Rating Scale (center care) and the Family Day Care Rating Scale (family day care). Results of descriptive and multivariate regression analyses are presented. Less than one-third of poor children were in Head Start. Child care quality was higher in Head Start centers than other centers, particularly among poor children (4.75 vs. 4.28, p < 0.001), Hispanics (4.90 vs. 4.45, p < 0.001), and whites (4.89 vs. 4.51, p < 0.001). African Americans experienced the lowest quality care in both Head Start and non-Head Start centers. Quality disadvantage was associated with Head Start family care settings, especially for low birthweight children (2.04 in Head Start vs. 3.58 in non-Head Start, p < 0.001). Lower family day care quality was associated with less maternal education and African American and Hispanic ethnicity. Center-based Head Start provides higher quality child care for at-risk children, and expansion of these services will likely facilitate school readiness in these populations. Quality disadvantages in Head Start family day care settings are worrisome and warrant investigation. PMID:22392601

Studies of the association between indoor allergen exposure and the development of allergic diseases have often measured allergen exposure at one point in time. We investigated the variability of house dust mite (Der p 1, Der f 1) and cat (Fel d 1) allergen in Dutch homes over a period of 8 years. Data were obtained in the Dutch PIAMA birth cohort study. Dust from the child's mattress, the parents' mattress and the living room floor was collected at four points in time, when the child was 3 months, 4, 6 and 8 years old. Dust samples were analysed for Der p 1, Der f 1 and Fel d 1 by sandwich enzyme immuno assay. Mite allergen concentrations for the child's mattress, the parents' mattress and the living room floor were moderately correlated between time-points. Agreement was better for cat allergen. For Der p 1 and Der f 1 on the child's mattress, the within-home variance was close to or smaller than the between-home variance in most cases. For Fel d 1, the within-home variance was almost always smaller than the between-home variance. Results were similar for allergen levels expressed per gram of dust and allergen levels expressed per square metre of the sampled surface. Variance ratios were smaller when samples were taken at shorter time intervals than at longer time intervals. Over a period of 4 years, mite and cat allergens measured in house dust are sufficiently stable to use single measurements with confidence in epidemiological studies. The within-home variance was larger when samples were taken 8 years apart so that over such long periods, repetition of sampling is recommended.

The incidence of end-stage renal failure is high and it is responsible for the increase of the rate of morbidity and mortality rates among our patients. The objective is to study patient characteristics before starting hemodialysis and to evaluate factors influencing their short and long term survival. This is a prospective study of 127 patients starting hemodialysis between June and December 2001. On May 31, 2005, their survival was analyzed according to different parameters. Patients were 77 males and 50 females. Their mean age was 51.4 +/- 16.1 years (15 to 78 years). Diabetes was observed in 33.9% of cases. Only 70.9% of patients were covered by a social service. Chronic renal failure was diagnosed at the end stage in 34.6% of cases. Before starting hemodialysis, only 4 patients were vaccinated against B hepatitis and arteriovenous fistula were not made in any patients. Pericarditis was observed in 9.4% of patients. Albuminemia was < 35 g/l in 60.5% of patients. First hemodialysis session was programmed in 53.5% of patients and realized urgently in 46.3% of patients. Patients were hemodialysed 4, 8 and 12 hours per week respectively in 16.5%, 15.8% and 67.7% of cases. On May 31, 2005, 35.4% of patients died. Their actuarial survivals at 3 months, 1 year and 4 years were respectively at 87.5%, 79.5% and 64.4%. Acturial survival was bad in patients with pericarditis, diabetes, hemodialysed less than 12 hours/week and when the first hemodialysis session was started urgently. The diagnosis of renal failure was frequently made at end-stage. There are no preparations before starting hemodialysis. We have to reinforce prevention programmes and increase the number of nephrologists and nephrology departments.

In recent years, deep trunk muscle training has been adopted in various sports, including swimming. This is performed both in everyday training and as part of the warm-up routine before competitive races. It is suggested that trunk stabilization exercises are effective in preventing injury, and aid in improving performance. However, conclusive evidence of the same is yet to be obtained. The time of start phase of swimming is a factor that can significantly influence competition performance in a swimming race. If trunk stabilization exercises can provide instantaneous trunk stability, it is expected that they will lead to performance improvements in the start phase of swimming. The purpose of this study was to investigate the immediate effect of trunk stabilization exercises on the start phase in swimming. Intervention study. Nine elite male swimmers (mean age 20.2 ± 1.0 years; height 174.4 ± 3.5 cm; weight 68.9 ± 4.1 kg) performed the swimming start movement. The measurement variables studied included flying distance, and the time and velocity of subjects at hands' entry and on reaching five meters. Measurements were taken in trials immediately before and after the trunk stabilization exercises. A comparison between pre- and post-exercise measurements was assessed. The time to reach five meters (T 5m ) decreased significantly after trunk stabilization exercises, by 0.019 s (p = 0.02). Velocity at entry (V entry ) did not demonstrate significant change, while velocity at five meters (V 5m ) increased significantly after the exercises (p = 0.023). In addition, the speed reduction rate calculated from V entry and V 5m significantly decreased by 5.17% after the intervention (p = 0.036). Trunk stabilization exercises may help reduce the time from start to five meters in the start phase in swimming. The results support the hypothesis that these exercises may improve swimming performance. Level 3b.

We sought to examine the association between job tenure and lost-time claim rates over a 10-year period in Ontario, Canada. Data were obtained from workers' compensation records and labour force survey data from 1999 to 2008. Claim rates were calculated for gender, age, industry, occupation, year and job tenure group. A multivariate analysis and examination of effect modification were performed. Differences in injury event and source of injury were also examined by job tenure. Lost-time claim rates were significantly higher for workers with shorter job tenure, regardless of other factors. Claim rates for new workers differed by gender, age and industry, but remained relatively constant at an elevated rate over the observed time period. This study is the first to examine lost-time claim rates by job tenure over a time period during which overall claim rates generally declined. Claim rates did not show a convergence by job tenure. Findings highlight that new workers are still at elevated risk, and suggest the need for improved training, reducing exposures among new workers, promoting permanent employment, and monitoring work injury trends and risk factors.

Including Short Period Constraints In the Construction of Full Waveform Tomographic Models

Thanks to the introduction of the Spectral Element Method (SEM) in seismology, which allows accurate computation of the seismic wavefield in complex media, the resolution of regional and global tomographic models has improved in recent years. However, due to computational costs, only long period waveforms are considered, and only long wavelength structure can be constrained. Thus, the resulting 3D models are smooth, and only represent a small volumetric perturbation around a smooth reference model that does not include upper-mantle discontinuities (e.g. MLD, LAB). Extending the computations to shorter periods, necessary for the resolution of smaller scale features, is computationally challenging. In order to overcome these limitations and to account for layered structure in the upper mantle in our full waveform tomography, we include information provided by short period seismic observables (receiver functions and surface wave dispersion), sensitive to sharp boundaries and anisotropic structure respectively. In a first step, receiver functions and dispersion curves are used to generate a number of 1D radially anisotropic shear velocity profiles using a trans-dimensional Markov-chain Monte Carlo (MCMC) algorithm. These 1D profiles include both isotropic and anisotropic discontinuities in the upper mantle (above 300 km depth) beneath selected stationsand are then used to build a 3D starting model for the full waveform tomographic inversion. This model is built after 1) interpolation between the available 1D profiles, and 2) homogeneization of the layered 1D models to obtain an equivalent smooth 3D starting model in the period range of interest for waveform inversion. The waveforms used in the inversion are collected for paths contained in the region of study and filtered at periods longer than 40s. We use the spectral element code "RegSEM" (Cupillard et al., 2012) for forward computations and a quasi-Newton inversion approach in which kernels are computed using normal

Hydrologic Drought of Water Year 2006 Compared with Four Major Drought Periods of the 20th Century in Oklahoma

Tortorelli, Robert L.

2008-01-01

Water Year 2006 (October 1, 2005, to September 30, 2006) was a year of extreme hydrologic drought and the driest year in the recent 2002-2006 drought in Oklahoma. The severity of this recent drought can be evaluated by comparing it with four previous major hydrologic droughts, water years 1929-41, 1952-56, 1961-72, and 1976-81. The U.S. Geological Survey, in cooperation with the Oklahoma Water Resources Board, completed an investigation to summarize the Water Year 2006 hydrologic drought and compare it to the four previous major hydrologic droughts in the 20th century. The period of water years 1925-2006 was selected as the period of record because before 1925 few continuous record streamflow-gaging sites existed and gaps existed where no streamflow-gaging sites were operated. Statewide annual precipitation in Water Year 2006 was second driest and statewide annual runoff in Water Year 2006 was sixth driest in the 82 years of record. Annual area-averaged precipitation totals by the nine National Weather Service Climate Divisions from Water Year 2006 are compared to those during four previous major hydrologic droughts to show how rainfall deficits in Oklahoma varied by region. Only two of the nine climate divisions, Climate Division 1 Panhandle and Climate Division 4 West Central, had minor rainfall deficits, while the rest of the climate divisions had severe rainfall deficits in Water Year 2006 ranging from only 65 to 73 percent of normal annual precipitation. Regional streamflow patterns for Water Year 2006 indicate that Oklahoma was part of the regionwide below-normal streamflow conditions for Arkansas-White-Red River Basin, the sixth driest since 1930. The percentage of long-term stations in Oklahoma (with at least 30 years of record) having below-normal streamflow reached 80 to 85 percent for some days in August and November 2006. Twelve long-term streamflow-gaging sites with periods of record ranging from 62 to 78 years were selected to show how streamflow

This study examined whether Head Start, the nation’s main two-generation program for low-income families, benefits children in part through positive changes in parents’ use of spanking and reading to children. Data were drawn from the 3-year-old cohort of the national evaluation of the Head Start program known as the Head Start Impact Study (N = 2,063). Results indicated that Head Start had small indirect effects on children’s spelling ability at age 4 and their aggression at age 4 through an increase in parents’ reading to their children. Taken together, the results suggest that parents plays a role in sustaining positive benefits of the Head Start program for children’s behavior and literacy skills, one that could be enhanced with a greater emphasis on parent involvement and education.

Laval R, Enrique

2009-04-01

Scarlet fever is endemic in Chile, with relatively low morbidity and periodic exacerbations every 4 or 5 years, which can become epidemics. From 1921 to 1927, the number of patients hospitalized in the country fluctuated from 15 to 65 per year, until an epidemic involving nearly 3.000 patients started at the end of 1928 and continued during all 1929. 978 patients died, 537 (52.5%) were from Santiago. Public Health authorities confronted this emergency with prevention, prophylaxis, isolation and treatment measures and 558 beds were disposed for patient hospitalization. Vaccination trials were undertaken and specific treatment with antitoxins was used in patients with toxic clinical cases, having satisfactory results. Convalescent patients were controlled in order to stop the spread of the infection. After approximately 3 years, this disease returned to its regular endemicity.

The aims of the present study are to analyse the association between marital status at age 24, 29, 34, and 39 years and subsequent mortality in a cohort of men born in 1953 (sensitive period); to study the impact of number of years married, number of years divorced/widowed, and number of marital break-ups on mortality (cumulative effect), and to examine whether these effects were independent of marital status at age 39 (proximity effect). Prospective birth cohort study with follow-up of mortality from 1992 to 2002. Participants were 10891 men born within the metropolitan area of Copenhagen, Denmark. Marital status in 1992 as well as start and termination of all previous marital status events from 1968 to 1992 were retrieved from the Danish Civil Registration System. Were hazard ratios (HR) for all-cause mortality from age 40 to 49 years. We found a strong protective effect of being married compared with never being married or divorced/widowed at every age. The association increased in strength with increasing age. Number of years divorced was associated with increased mortality risk in a dose-dependent manner at age 34 and 39 years. One or more marital break-ups was associated with higher mortality, whereas increasing number of years married was associated with lower mortality. Inclusion of current marital status attenuated the strength of the associations but most of them remained statistically significant. Marital status and cumulated marital periods, especially cumulated periods divorced/widowed are strong independent predictors of mortality among younger males.

School start times and teenage driver motor vehicle crashes.

Shifting school start times to 8:30 am or later has been found to improve academic performance and reduce behavior problems. Limited research suggests this may also reduce adolescent driver motor vehicle crashes. A change in the school start time from 7:30 am to 8:45 am for all public high schools in one North Carolina county presented the opportunity to address this question with greater methodologic rigor. We conducted ARIMA interrupted time-series analyses to examine motor vehicle crash rates of high school age drivers in the intervention county and 3 similar comparison counties with comparable urban-rural population distribution. To focus on crashes most likely to be affected, we limited analysis to crashes involving 16- & 17-year-old drivers occurring on days when school was in session. In the intervention county, there was a 14% downward shift in the time-series following the 75 min delay in school start times (p = .076). There was no change approaching statistical significance in any of the other three counties. Further analysis indicated marked, statistically significant shifts in hourly crash rates in the intervention county, reflecting effects of the change in school start time on young driver exposure. Crashes from 7 to 7:59 am decreased sharply (-25%, p = .008), but increased similarly from 8 to 8:59 am (21%, p = .004). Crashes from 2 to 2:59 pm declined dramatically (-48%, p = .000), then increased to a lesser degree from 3 to 3:59 pm (32%, p = .024) and non-significantly from 4 to 4:59 (19%, p = .102). There was no meaningful change in early morning or nighttime crashes, when drowsiness-induced crashes might have been expected to be most common. The small decrease in crashes among high school age drivers following the shift in school start time is consistent with the findings of other studies of teen driver crashes and school start times. All these studies, including the present one, have limitations, but the similar

To evaluate a new prenatal education program evaluation tool, the UpStart Parent Survey - Prenatal, in terms of: (a) reliability and validity; (b) sensitivity to change over time; (c) whether results differed for mothers versus fathers; and (d) whether results differed when using an electronic tablet-computer versus a paper survey. Psychometric study. Participants were 277 expectant mothers (n = 161) and fathers (n = 106) enrolled in Childbirth Essentials, a 6-week prenatal education program. The UpStart Parent Survey - Prenatal is a retrospective pretest/posttest survey with three scales: Parenting Knowledge, Parenting Experience, and Program Satisfaction, and three open-ended questions. The UpStart Parent Survey - Prenatal is sensitive to change and demonstrated significant positive differences in parenting knowledge and parenting experience. There was no difference in results whether the survey was completed by mothers or fathers. Results were similar whether paper or electronic formats were used. The survey was easy to complete. The UpStart Parent Survey - Prenatal holds promise as a reliable and valid evaluation tool to capture outcomes of brief prenatal education programs that target the general population of expectant parents. © 2016 Wiley Periodicals, Inc.

Rodrigues, Dulcilea Ferraz; Goulart, Eugênio Marcos Andrade

2016-01-01

The number of studies on patch-test results in children and adolescents has gradually increased in recent years, thus stimulating reviews. This paper is a systematic review of a 15-year period devoted to studying the issue. Variations pertaining to the number and age groups of tested children and/or adolescents, the number of subjects with atopy/atopic dermatitis history, the quantity, type and concentrations of the tested substances, the test technique and type of data regarding clinical relevance, must all be considered in evaluating these studies, as they make it harder to formulate conclusions. The most common allergens in children were nickel, thimerosal, cobalt, fragrance, lanolin and neomycin. In adolescents, they were nickel, thimerosal, cobalt, fragrance, potassium dichromate, and Myroxylon pereirae. Knowledge of this matter aids health professionals in planning preventive programs aimed at improving children's quality of life and ensuring that their future prospects are not undermined.

The aim of our study was to investigate the changes in drug usage and financial expenditure according to legal changes in Croatia during the period 2001 - 2008, especially considering pricing policy. The data on outpatient drug usage during the studied period was obtained from the Croatian National Health Insurance (CNHI). CNHI maintains a database on drugs prescribed by primary health care physicians and dispensed by pharmacies. The data was calculated and presented in defined daily doses (DDD) per inhabitant per year for antibiotics and in DDD/1,000 inhabitants/day for other drugs. The data is also presented in Euro/DDD and the financial expenditures are presented in Euros. During the investigated period drug usage increased 81.33%, while financial expenditure increased 77.23%. While total DDD/1,000 increased ~ 10% every year, financial expenditure increased 10 - 20% annually until 2006, but since then there have been no significant changes. Pricing policy changes could influence drug financial expenditure considerably in the short-term, but it is also important to apply a combination of measures for drug expenditure control. Numerous interventions from authorities from different countries all over the world, prove that there is still no so called "gold standard" which could restrain growing usage and expenditure of drugs. Clinical pharmacologists and clinical pharmacists should be included in these processes.

The role of domain-specific practice, handedness, and starting age in chess.

PubMed

Gobet, Fernand; Campitelli, Guillermo

2007-01-01

The respective roles of the environment and innate talent have been a recurrent question for research into expertise. The authors investigated markers of talent, environment, and critical period for the acquisition of expert performance in chess. Argentinian chess players (N = 104), ranging from weak amateurs to grandmasters, completed a questionnaire measuring variables including individual and group practice, starting age, and handedness. The study reaffirms the importance of practice for reaching high levels of performance, but it also indicates a large variability: The slower player needed 8 times as much practice to reach master level than the faster player. Additional results show a correlation between skill and starting age and indicate that players are more likely to be mixed-handed than individuals in the general population; however, there was no correlation between handedness and skill within the sample of chess players. Together, these results suggest that practice is a necessary but not sufficient condition for the acquisition of expertise, that some additional factors may differentiate chessplayers and nonchessplayers, and that starting age of practice is important.

Background Dengue is a major global public health problem with increasing incidence and geographic spread. The epidemiology is complex with long inter-epidemic intervals and endemic with seasonal fluctuations. This study was initiated to investigate dengue transmission dynamics in Binh Thuan province, southern Vietnam. Methodology Wavelet analyses were performed on time series of monthly notified dengue cases from January 1994 to June 2009 (i) to detect and quantify dengue periodicity, (ii) to describe synchrony patterns in both time and space, (iii) to investigate the spatio-temporal waves and (iv) to associate the relationship between dengue incidence and El Niño-Southern Oscillation (ENSO) indices in Binh Thuan province, southern Vietnam. Principal Findings We demonstrate a continuous annual mode of oscillation and a multi-annual cycle of around 2–3-years was solely observed from 1996–2001. Synchrony in time and between districts was detected for both the annual and 2–3-year cycle. Phase differences used to describe the spatio-temporal patterns suggested that the seasonal wave of infection was either synchronous among all districts or moving away from Phan Thiet district. The 2–3-year periodic wave was moving towards, rather than away from Phan Thiet district. A strong non-stationary association between ENSO indices and climate variables with dengue incidence in the 2–3-year periodic band was found. Conclusions A multi-annual mode of oscillation was observed and these 2–3-year waves of infection probably started outside Binh Thuan province. Associations with climatic variables were observed with dengue incidence. Here, we have provided insight in dengue population transmission dynamics over the past 14.5 years. Further studies on an extensive time series dataset are needed to test the hypothesis that epidemics emanate from larger cities in southern Vietnam. PMID:20644621

J Strength Cond Res 31(1): 24-29, 2017-The purpose of the current study was to characterize the in-game heart rate (HR) responses of baseball pitching. In-game HR was recorded from 16 professional baseball starting pitchers (mean ± SD, age = 22.1 ± 1.3 years; height = 187.9 ± 4.4 cm; weight = 90.5 ± 9.5 kg) for a total of 682 innings (home = 381, away = 301). All analyzed HR data were then normalized to each pitcher's age-predicted maximal HR (%HRmax). The group mean ± SD in-game %HRmax among all pitchers was 84.8 ± 3.9%, suggesting that baseball pitching is predominantly an anaerobic task. A split-plot mixed-model repeated measures analysis of variance identified a significant interaction effect between inning and game location (p = 0.042). Follow-up simple effects indicated that the in-game %HRmax was significantly different across innings, but only during home starts (p < 0.001). Specifically, pairwise analyses indicated that the in-game %HRmax during home starts were significantly (p ≤ 0.05) higher in the first and second innings than in all other innings. In addition, follow-up simple effects indicated that the in-game %HRmax was significantly (p = 0.017) higher during home starts than away starts in the first inning (87.3 ± 3.6% vs. 85.8 vs. 3.8%, respectively). Thus, it is possible that inning-dependent psychological factors may have contributed to the observed changes in in-game physiological intensity across innings and that these factors are specific to game location. Consequently, strength and conditioning practitioners should prescribe high-intensity exercises when developing conditioning programs for professional baseball starting pitchers.

The aim of this study was to investigate the stability of associations between social factors, as assessed by maternal occupation and education, and poor birth condition (an Apgar score of below 7 at 1 and 5 minutes) over a 30-year period in Sweden. The dataset was based on infants born in Sweden between 1973 and 2002. Poor birth condition was defined as an Apgar score below 7 at 1 and 5 minutes. Logistic regression was used to investigate the association of between socioeconomic status and poor birth condition. In the adjusted model, mothers in non-manual occupations (OR 0.91 (0.88, 0.95)) or with higher educational status (OR 0.88 (0.84, 0.93)) were less likely to have an infant born in poor condition than the reference group. Limiting the analysis to the last decade showed less evidence for an association (OR 0.94 (0.86, 1.02) and OR 0.94 (0.82, 1.09), respectively). While maternity, delivery and child healthcare are free of charge in Sweden, poor birth condition was more common among infants of mothers in manual occupations or low levels of education. However, this association appeared to attenuate over the calendar period studied.

Does Head Start differentially benefit children with risks targeted by the program’s service model?☆

Data from the Head Start Impact Study (N = 3540) were used to test for differential benefits of Head Start after one program year and after kindergarten on pre-academic and behavior outcomes for children at risk in the domains targeted by the program’s comprehensive services. Although random assignment to Head Start produced positive treatment main effects on children’s pre-academic skills and behavior problems, residualized growth models showed that random assignment to Head Start did not differentially benefit the pre-academic skills of children with risk factors targeted by the Head Start service model. The models showed detrimental impacts of Head Start for maternal-reported behavior problems of high-risk children, but slightly more positive impacts for teacher-reported behavior. Policy implications for Head Start are discussed. PMID:26379369

The mean age of starting hemodialysis (HD) in patients with end-stage renal failure is gradually increasing in Japan. It is not uncommon for HD to be commenced in bedridden elderly patients who cannot give informed consent, because of brain damage. However, we have not been able to provide useful advice to their families because there was no relevant information available about the prognosis of bedridden patients on HD. Therefore, we examined the prognosis of bedridden HD patients. Two hundred and nineteen patients who received HD were enrolled. These subjects were divided into five groups; (aged <50, 50-59, 60-69, 70-79, and >or=80 years at the commencement of HD), and we compared the overall prognosis between bedridden and nonbedridden patients, as well as that for each age group. There were 76 bedridden patients among the 219 HD patients, and the main cause of their bedridden state before starting HD was cerebrovascular disease. The 50% survival time after the start of HD was 120 months for the nonbedridden patients versus 56 months for bedridden patients. However, the mean (+/-SD) age of the bedridden patients was higher than that of nonbedridden patients (70 +/- 13 versus 64 +/- 14 years). In patients under age 50 years at the start of dialysis, the survival rate was lower in the bedridden than in the nonbedridden patients, but there were no differences between survival rates for bedridden and nonbedridden patients in the other four age groups. The prognosis of HD patients is poor compared with the general life expectancy of the Japanese population, but whether these patients are bedridden or not has little influence on their survival.

Owing to the encouraging data on fellowship training in robotic pyeloplasty and the documented benefits of robotic pyeloplasty, the aim of this study was to test the feasibility of starting up pediatric urological robotic surgery in a center with a limited case volume. The operative parameters and clinical outcome of the first 25 robotic pyeloplasties performed were compared to data on open and laparoscopic procedures from the previous 5 year period. The fellow was the only console surgeon. An experienced non-robotic pediatric urologist was supervising at the patient site. The learning curve was in accordance with previously published data on fellows. The median operating time in robotic surgery was 182 min and was significantly shorter than in laparoscopic surgery (median 250 min) and the postoperative inpatient length of stay was significantly shorter after robotic surgery (median 1 day) than after both laparoscopic (median 2 days) and open surgery (median 3.5 days). For robotic cases, postoperative renography showed either stable or increased function of the hydronephrotic kidney. The only complication was in one case with ureteral orifice edema after JJ-stent removal, requiring nephrostomy for 6 weeks. The benefits of overall shorter postoperative hospital stay after robotic pyeloplasty and faster operating time compared to the laparoscopic procedure are clearly in accordance with data from the recent literature. The fast learning curve for robotic pyeloplasty will allow pediatric urology fellowship programs to be integrated in the start-up phase of a pediatric robotic program even though the case material is limited. Operative success rates were in accordance with the gold standard of open surgery.

Reminiscence of my Sixty-five year Voyage in Astronomy

I returned to China from the United Kingdom in 1953, then worked in Purple Mountain Observatory. It was the early days of new China. The elder generation of astronomers was undertaking an effort of “repairing broken and filling defect” during those post-war years, and started planning and laying the foundation of modern astronomy. Under their leadership, I started a journey of astronomy whose main task was construction. The journey has been full of twists and turns. As a result of the “Great Leap Forward” in 1958 and the 1966 launch of the decade-long “Cultural Revolution” period, the situation of construction in astronomy was similar to that in other sciences, suffering bad effects. Not until the “Reform and Opening up” period after those events was construction able to continue, and various disciplines and international connections began to open. A “passage” had gradually developed. In this new circumstance, I kept pursuing the pioneers to explore a forward direction. Looking back today, this journey has been three periods of a four generation relay. This article is divided into three sections that describe my research work in these times that I recall: (1) Looking back at the beginning of the return and tracing the footprints of the founders. (2) Recalling my radio astronomy tour. (3) Retrospection and expectation of LAMOST.

The epidemiology and clinical association of enterovirus (EV) and parechovirus (HPeV) infections, as well as the type-distribution-according-to-age, were determined during a 4-year study period in Spain. During 2010-2013, a total of 21,832 clinical samples were screened for EV and the detection frequency was 6.5% (1,430). Of the total EV-negative samples, only 1,873 samples from 2011 to 2013 were available for HPeV testing. HPeV was detected in 42 (2%) of them. Positive samples were genotyped using PCR and sequencing. EV infections occurred in all age groups of patients: neonates (17%), children 28 days to 2 years (29%), children 2-14 years (40%), and adults (14%). Thirty-four different EV types were identified. HPeV infections were detected exclusively in infants <8 m (70% neonates, P < 0.05). All but one HPeV were HPeV-3. Differences in type frequency detection were found according to age and clinical manifestation. Coxsackievirus (CV)-B4 (61%), CV-B5 (83%), and HPeV-3 (64%) were more frequent in neonates than in older patients (P < 0.05). Echovirus (E)-3 (60%), E-18 (47%), E-25 (62%), CV-A6 (61%), CV-A16 (72%), and EV-71 (75%) were mainly detected in children 28 days to 2 years (P < 0.05), whereas, E-6 (79%), E-20 (88%), and E-30 (85%) were predominant in children >2 years and adults (P < 0.05). Clinically, meningitis was associated with EV (P < 0.01) whereas, encephalitis was more frequent in HPeV-infected patients. CV-B types were associated with myocarditis (90%; P < 0.05) and EV species A with hand-foot-mouth-disease/atypical exanthema (88%; P < 0.05). J. Med.

To analyze the development of recurrent pain in 3 body locations in children and adolescents (baseline age, 9 to 14 years) in a 4-year period. In a large population-based longitudinal epidemiological study data was collected through annual postal questionnaires (longitudinal, n = 2025). Descriptive statistics and generalized estimating equations were used. Girls were more likely to report recurrent pain, demonstrated a steeper development during the 4-year period, and reported multiple pain more often than boys. Younger children reported less recurrent pain, but displayed a steeper trend of increasing prevalence rates as they grew older. Older children illustrated a more stable development of recurrent pain and reported multiple pain more often. Disability experienced because of recurrent pain was related strongest to pain intensity. Stable patterns of pain were related to higher intensity and disability reports. The children experienced headache as the most disabling of the 3 pains. The results show that boys and girls report recurrent pain in different patterns in the years. To identify risk factors, analysis should be performed separately for boys and girls. Furthermore, it is recommended to include children before the age of 9 years in a prevention study. Copyright © 2011 Mosby, Inc. All rights reserved.

Hypertension and left ventricular hypertrophy (LVH) are commonly associated in patients with CRF starting RDT. We report a case of eccentric LVH with marked dilatation and subsequent mitral incompetence of +3/4 that disappeared after three months of standard hemodialysis. Mrs SN, 62 years old, starting HD, had an echocardiography because of dyspnoea; the echo showed: dilated left atrium (78 ml/m2), moderately dilated left ventricle with normal systolic function (TDV 81 ml/m2, EF 66%), an increased ventricular mass (120 gr/m2) and a high grade mitral incompetence +3/4. After three months standard RDT and a dry weight only 2 kg less, the patients was normotensive without therapy, a cardiac angiogram with a hemodynamic study was performed as a pre-transplant workout: a normal left ventricle was found with normal systolic function (TDV 66, TSV 17, GS 49, EF 75%), and a perfectly competent mitral valve (reflux disappeared). The coronary angiography did not reveal critical stenosis. A new echocardiography confinned the data of the hemodynamic study: hypertensive cardiomiopathy with normal systolic function. After one year the patient has been transplanted, with a good renal function and the cardiac echo unchanged. Relieving uremic toxicity ameliorated the cardiac performance in this particular patient.
