Patients with an acute basilar artery occlusion (BAO) have a high risk of long-lasting disability and death. Only limited data are available on functional outcome in elderly patients with BAO. Using data from the Basilar Artery International Cooperation Study, we aimed to determine outcomes in patients ≥75 years. Primary outcome measure was poor functional outcome (modified Rankin scale score 4-6). Secondary outcomes were death, insufficient vessel recanalization (defined as thrombolysis in myocardial infarction score 0-1) and symptomatic intracranial hemorrhage (SICH). Patients were divided into four age-groups, based on quartiles: 18-54, 55-64, 65-74, and ≥75 years. Outcomes were compared between patients ≥75 years and patients aged 18-54 years. Risk ratios with corresponding 95 % confidence intervals (CI) were calculated and Poisson regression analyses were performed to calculate adjusted risk ratios (aRR). We included 619 patients [18-54 years n = 153 (25 %), 55-64 years n = 133 (21 %), 65-74 years n = 171 (28 %), and ≥75 years n = 162 (26 %)]. Compared with patients aged 18-54 years, patients ≥75 years were at increased risk of poor functional outcome [aRR 1.33 (1.14-1.55)] and death [aRR 2.47 (1.75-3.51)]. Nevertheless, 35/162 (22 %, 95 % CI 15-28 %) of patients ≥75 years had good functional outcome. No significant differences between age groups were observed for recanalization rate and incidence of SICH. Although patients ≥75 years with BAO have an increased risk of poor outcome compared with younger patients, a substantial group of patients ≥75 years survives with a good functional outcome.

Objective: To determine the optimal contrast protocols for 64-slice spiral CT coronary angiography in order to reduce the volume of contrast injection. Methods: One hundred fifty patients scheduled to undergo 64-slice spiral CT coronary angiography were prospectively randomized into the following five groups with different injection protocols: group 1: uniphasic injection without a flush; group 2: biphasic injection with a flush; group 3, group 4 and group 5 : triphasic injection with a diluted contrast material with 3:7, 5:5, 7:3 contrast/saline ratio respectively. Attenuation was measured in the right atrium, right ventricle, left atrium, left ventricle, ascending aorta, right coronary artery and left coronary artery and analyzed with single factor variance test (ANOVA). The quality of the coronary artery images was evaluated and compared using person Chi-Square. Results: The total contrast material volume were (67.0±5.3) ml, (59.9±4.9) ml, (62.9±3.2) ml, (69.2±5.7) ml and (70.9±4.6) ml in five groups respectively (F=27.43, P 2 =18.81, P 2 =31.44, P<0.01). The artifacts in the superior vena cava in group 1 was the most, and in group 2 was the least. The mean enhancement values of right and left coronary arteries in group 2 were significantly greater than those in other groups (F=2.47 and 4.10, P<0.05). The visualization of both left ventricle and right ventricle cavities was the best in group 3. Conclusion: Biphasic injection and triphasic injection are better than uniphasic injection for 64-slice spiral CT coronary angiography and triphasic injection is better than biphasic injection for the visualization of both left ventricle and right ventricle cavities.

The only mutations that reduced the ability of the beta-subunit to suppress calmodulin phosphorylation activity, though being compatible with normal reconstitution of CK2 holoenzyme, were those affecting Asp55, Glu57...... are conversely ineffective. The latent "calmodulin kinase" activity of CK2 can also be specifically unmasked by a peptide (alpha[66-86]) reproducing a basic insert of the catalytic subunit. This effect is reversed by equimolar addition of a peptide (beta[55-71]) including the 55-64 acidic stretch of the beta......-subunit. Comparable polylysine stimulation was observed with the holoenzymes reconstituted with either beta wt or the beta mutants capable of assembling with the alpha-subunit, with the notable exception of those bearing Ala substitutions for acidic residues at positions 55, 57, and 59-61. These were nearly...

Full Text Available Background. The incidence of dementia is growing due to the aging of the population. Active search for the population at risk is necessary. Short cognitive screening tests are one of the most suitable ways of doing that. The most often used test of this kind is Mini Mental State Examination (MMSE. Its distinctive features are simplicity and shortness. Kratek preizkus spoznavnih sposobnosti (KPSS – Slovenian version of MMSE has been used in Slovenia since 1984, although there were no normative values for Slovenian population, which restricted its applicability and use in clinical practice. The aim of the present paper was to obtain the normative values for KPSS for different age and educational groups in population of adults older than 55 years. Our hypothesis was that test results would be significantly dependent on age and education which will justify the extensive nature of the study.Methods. Some parts of the test were modified based on clinical experience in last years. The modified KPSS was used for testing at general practices in Ljubljana, Maribor and Novo mesto. The research comprised of KPSS testing in 154 volunteers, mean age 65.1 (ranged from 55 to 87 years. None of them had a diagnosis of dementia or other active psychiatric or neurologic ilness.Results. We found that KPSS results are not influenced by gender. The volunteers were aranged in four age groups at five years intervals. Statistically significant differences (p < 0.0002 for the mean results among different age groups were found. The volunteers were further divided in groups according to the level of education and the differences in mean results among the educational groups were statistically significant (p < 0.0000. Normative values for the age and education groups were obtained.Conclusions. The main result of our study are KPSS normative values for different age and education groups of Slovenians. The mean results on KPSS are significantlly dependent on age and education

Coltman, C.A. Jr.; Dixon, D.O.

1982-01-01

Thirty-two second malignancies (21 acute leukemias and 11 solid tumors) were identified among 659 patients with all stages of Hodgkin's disease treated by members of the Southwest Oncology Group. There were no leukemias and one solid tumor among 95 patients treated with radiotherapy alone. The actuarial risk of developing acute leukemia at 7 years was 6.2% for chemotherapy alone, 6.4% for combined modality, and 7.7% for salvage chemotherapy. The incidence of acute leukemia was higher (P . 0.002) among those whose treatment began at greater than or equal to 40 years of age. The actuarial risk of leukemia in that group was 20.7% at 7 years. These data are compatible with the hypothesis that chemotherapy alone, combined modality, and salvage chemotherapy have an equivalent oncogenic potential and that patients greater than or equal to 40 years of age have an enhanced susceptibility to these oncogenic stimuli

Full Text Available ABSTRACT Objective To ascertain whether modifiable physical performance–based measurements predicted 5.5-year mortality in a riparian elderly cohort in the Amazon rainforest region. Methods A longitudinal study evaluating the impact of functional determinants on 5.5-year mortality in a riparian elderly cohort from Maués City in the state of Amazonas, Brazil, was performed. The study was a follow-up of a previous observational investigation that evaluated various fitness tests in 630 Amazonian riparian elderly (291 males and 339 females aged 72.3 ± 8.0 (60–99 years old. The cohort was selected for its adverse environmental conditions, which increased the risk of falls yet required maintenance of good physical condition for carrying out relatively rigorous daily activities, and restricted access to specialized health services. Official death records were obtained from the Maués Municipal Health Department. Results A total of 80 study participants (12.7% died over the 5.5-year study period. Kaplan-Meier regression analysis showed significant association between Timed Up and Go (TUG test scores ≥ 14 seconds and mortality risk, independent of sex, age, and other health variables. Conclusions The study results suggest that the TUG test can be used as an indicator for initiating therapeutic and preventive actions, including conducting exercises or physical activities adapted to the health and functional conditions of the elderly, by identifying elderly people with a higher relative risk of mortality.

In 2015, an estimated 18.4 million U.S. adults had current asthma, and 3,396 adult asthma deaths were reported (1). An estimated 11%-21% of asthma deaths might be attributable to occupational exposures (2). To describe asthma mortality among persons aged 15-64 years,* CDC analyzed multiple cause-of-death data † for 1999-2016 and industry and occupation information collected from 26 states § for the years 1999, 2003, 2004, and 2007-2012. Proportionate mortality ratios (PMRs) ¶ for asthma among persons aged 15-64 years were calculated. During 1999-2016, a total of 14,296 (42.9%) asthma deaths occurred among males and 19,011 (57.1%) occurred among females. Based on an estimate that 11%-21% of asthma deaths might be related to occupational exposures, during this 18-year period, 1,573-3,002 asthma deaths in males and 2,091-3,992 deaths in females might have resulted from occupational exposures. Some of these deaths might have been averted by instituting measures to prevent potential workplace exposures. The annual age-adjusted asthma death rate** per 1 million persons aged 15-64 years declined from 13.59 in 1999 to 9.34 in 2016 (pindustries and occupations underscores the importance of optimal asthma management and identification and prevention of potential workplace exposures.

Acephate is a commercial organophosphate pesticide formerly used in households and now used primarily for agriculture. Poisoning symptoms include salivation, lacrimation, urination, defecation, gastrointestinal illness, and emesis. In addition to these classic symptoms, neurodegeneration can result from increased and continued exposure of organophosphates. This 55-year-old woman presented with organophosphate-induced delayed neuropathy in the form of quadriplegia due to the commonly used pesticide acephate. She was exposed to this pesticide through multiple sprayings in her work office with underrecognized poisoning symptoms. She presented to her primary care physician with neuropathic pain and paralysis in her arm following the sprayings and eventual complete paralysis. The patient lived for 2 years following her toxic exposure and quadriplegia. A complete autopsy after her death confirmed a transverse myelitis in her spinal cord. We conclude that in susceptible individuals, acephate in excessive amounts can produce severe delayed neurotoxicity as demonstrated in animal studies.

The 2010 Global Burden of Disease estimates show that 57% of all TB deaths globally occurred among adults older than 50 years of age. Few studies document the TB burden among older adults in Southern Africa. We focused on adults older than 55 years to assess the relative TB burden and associated demographic factors. A cross sectional nationally representative TB prevalence survey conducted of Zambian residents aged 15 years and above from 66 clusters across all the 10 provinces of Zambia. Evaluation included testing for TB as well as an in-depth questionnaire. We compared survey data for those aged 55 and older to those aged 15-54 years. Survey results were also compared with 2013 routinely collected programmatic notification data to generate future hypotheses regarding active and passive case finding. Among older adults with TB, 30/ 54 (55.6%) were male, 3/27 (11.1%) were HIV infected and 35/54 (64.8%) lived in rural areas. TB prevalence was higher in those aged ≥55 (0.7%) than in the 15-54 age group (0.5%). Males had higher rates of TB across both age groups with 0.7% (15-54) and 1.0% (≥55) compared with females 0.4% (15-54) and 0.6% (≥55). In rural areas, the prevalence of TB was significantly higher among older than younger adults (0.7% vs 0.3%), while the HIV infection rate was among TB patients was lower (11.1% vs 30.8%). The prevalence survey detected TB in 54/7484 (0.7%) of older adults compared to 3619/723,000 (0.5%) reported in 2013 programmatic data. High TB rates among older adults in TB endemic areas justify consideration of active TB case finding and prevention strategies.

Full Text Available The scientific research of this paper focuses on the involvement of the school age group 16-18 years old in sports betting games impacted by beliefs on luck and social groups. For the collection of data literature is utilized, questionnaires are distributed and also focus groups were conducted. The assumptions of the assignment are: a The involvement of school age group 16-18 years in sports betting games are manners learned from their comrades, b The school age group 16-18 years old attribute to fate the participation in sports betting games. Over 64% of responses manifest that they have learned the rules from their companions. The revelations and questionnaire responses argue that over 45% of students in their classes play sports bets, and 34% think that the phenomena of sports betting depends on luck. The major part of this age group do not practice and believe in fortunate rituals or activities. The acquired data reflect that the extent of involvement of this age group is in substantial dimensions. We suggest that the decision-making bodies and service providers should develop strategies in order to reduce the phenomenon.

The use of e-mail-based telemedicine has been demonstrated as an effective and low-cost way of delivering healthcare to patients in remote areas who have limited access to medical services. We established a novel teleorthopedic service for a catchment area encompassing 972,000 km 2 using a commercial off-the-shelf e-mail application. Before the implementation of this program, patients with acute orthopedic injuries were required to travel by air up to 1,900 km for evaluation by an orthopedic surgeon. In the present study, we examined the patient demographics and consultation characteristics and calculated the cost savings associated with patient travel for this teleorthopedic service. We retrospectively reviewed 1,000 consecutive e-mail-based consults and radiographic images received for new patients with acute orthopedic injuries from January 2008 to June 2013. Seventy-nine consults were excluded due to incomplete documentation, leaving 921 available for analysis. The service records were examined to identify patient demographics, orthopedic diagnosis, the percentage of patients managed locally, and the medical indications for patients requiring transfer. As the travel costs for patients requiring transport to the university hospital center are borne by governmental health agencies, the savings accrued from treating patients in their home communities were also calculated. For the 921 consultations, the mean age of patients was 27 years (range, 3 months-88 years), with 40.7% of all patients being younger than 18 years. The most common diagnoses were ankle fractures (15.2%), clavicle fractures (11.2%), distal radius fractures (11.2%), and fractures of the foot (10.2%). One hundred ninety patients (20.6%) required transfer, whereas 731 patients (79.4%) were treated in their home communities. Of the patients who were transferred, 123 (64.7%) required surgery, 55 (28.9%) required clinical evaluation by an orthopedic surgeon, and 12 (6.4%) required CT or MRI. Cost

Since many years, the SL/BT group has developed specific G-64 hardware modules for the control of the fast pulsed magnets. Up to now, the integration of these modules into the accelerator control system has been done using a MIL1553 fieldbus in command/response mode connected to a LynxOS front-end. In 1996 and 1998, recommendations for the use of industrial fieldbuses and programmable logic controllers were issued at CERN. In order to integrate the existing G-64 hardware into this environment based on industrial components, an interface between the G-64 bus and the PROFIBUS-DP fieldbus has been developed. This interface is based on a modular and open hardware architecture with on one side an off-the-shelf industrial, fieldbus independent, interface and on the other side a FPGA (Field Programmable Gate Array). Required functionality has been implemented within the FPGA with VHDL (Very high-speed integrated circuit Hardware Description Language).

A random representative sample of 870 women aged 25–64 years from one of the Novosibirsk districts was surveyed within the third screening of the WHO «MONICA-psychosocial» (MOPSY program in 1994. The response rate was 72.5%. Hs was studied using the MOPSY test (the subscale «Hostility». Awareness and attitude towards health and preventive measures were assessed using the awareness and attitude towards health test. Chi-square test (χ2 was used to assess the statistical significance of differences between the groups.Results. The prevalence of high Hs was 43.9%. Women with high Hs rated negatively their health more frequently, complained of health complaints more often, and had poor awareness of preventive methods, much smoking, and inadequate physical activity. High Hs was associated with personal anxiety, major depression, high vital exhaustion, low social support, high family and job stresses.Conclusion. The prevalence of obvious Hs in a female population aged 25–64 years is high and it is associated with poor self-rated health, insufficient health care, and a large number of negative psychosocial factors.

Chih-Wei Chen

Full Text Available BACKGROUND: Statins reduce cardiovascular risks but increase the risk of new-onset diabetes (NOD. The aim of this study is to determine what effect, if any, statins have on the risk of NOD events in a population-based case-control study. An evaluation of the relationship between age and statin-exposure on NOD risks was further examined in a female Asian population. METHOD: In a nationwide case-controlled study, the authors assessed 1065 female NOD patients and 10650 controls with matching ages, genders and physician visit dates. The impact of statin-exposure on NOD was examined through multiple logistic regression models. Subgroup analysis for exploring the risk of NOD and statin-exposure in different age groups was performed. RESULTS: Statin-exposure was statistically significantly associated with increased new-onset diabetes risks using multivariate analysis. Interaction effect between age and statin-exposure on NOD risk was noted. For atorvastatin, the risk of cDDDs>60 was highest among the 55-64 year-olds (adjusted odds ratio [OR], 8.0; 95% confidence interval [CI], 2.57-24.90. For rosuvastatin, the risk of cDDDs>60 was highest among the 40-54 year-olds (adjusted OR, 14.8; 95% CI, 2.27-96.15. For simvastatin, the risk of cDDDs>60 was highest among the 55-64 year-olds (adjusted OR, 15.8; 95% CI, 5.77-43.26. For pravastatin, the risk of cDDDs>60 was highest among the 55-64 year-olds (adjusted OR, 14.0; 95% CI, 1.56-125.18. CONCLUSIONS: This population-based study found that statin use is associated with an increased risk of NOD in women. The risk of statin-related NOD was more evident for women aged 40-64 years compared to women aged 65 or more, and was cumulative-dose dependent. The use of statins should always be determined by weighing the clinical benefits and potential risks for NOD, and the patients should be continuously monitored for adverse effects.

Testicular torsion is predominantly a disease of adolescence, but age itself should not be an exclusion criterion for the diagnosis. A lack of suspicion for testicular torsion in older patients may result in a missed or delayed diagnosis which jeopardizes the chance of testicular salvage. In this article, we report a case of testicular torsion in a 55-year-old Chinese man.

To determine the impact of workplace stress on the hazard ratio (HR) of myocardial infarction (M) and stroke in an open female population aged 25-64 years in Russia/Siberia (Novosibirsk) for 16 years. A random representative sample of 25-64-year-old women (n=870) residing in a Novosibirsk district was surveyed within the framework of the WHO psychological> program. Workplace stress was investigated using the Karasek scale; an attitude towards work and health prophylactic examinations was studied applying the Health Awareness and Attitude questionnaire of the WHO psychological> program. For 16 years (1994 to 2010), a cohort of all new cases of MI and stroke was examined employing the WHO program and all possible medical records. The Cox regression model was used to determine HR for MI and stroke in the open female population aged 25-64 years for 16 years. The prevalence of high-level stress in the open female population aged 25-64 years was 31.6%. The high level of job stress was associated with a high responsibility, impossibility to have a rest at the end of a working day, frequent professional dissatisfaction, and a reduced work capacity. During 16 years, the women having high-level job stress showed a 3.22- and 1.96-fold increases in the HR of MI (p<0.05) and stroke (p<0.05), respectively. The incidence of MI and stroke was higher in married women expressing job stress as managers or manual laborers and having high and low educational attainment. The prevalence of high-level workplace stress was substantial in the open population of 25-64-year-old women in Russia/Siberia (Novosibirsk). The stress-related HR of Ml and stroke was 3-2 times higher than in those without high-level stress. The HR of MI and stroke is affected by a social gradient.

Full Text Available Abstract Background More people will probably continue working into old age in the future due to the increased size of aging populations in many countries. We therefore need to know more about older workers’ health in relation to their work situation and retirement. This study is a part of a theoretical development of older workers’ situations. Older workers’ situations are theoretically themed in nine areas by the authors of this study. The aims of the study were to investigate the relationship between: i diagnosed disease and factors in older workers’ situations, theoretically themed in nine areas; ii self-rated health and factors in older workers’ situations, theoretically themed in nine areas; iii diagnosed disease and self-rated health; and iv the relationships between these health measures and retirement. Methods A questionnaire-based cross-sectional study, using logistic regression, with 1,756 health care personnel aged 55–64 years. The questionnaire used gave an overview of most different areas in the older workers’ situations. Result There was a difference in the participants’ frequency of objectively specified diagnosed disease and their subjectively experienced self-rated health. A bad self-rated health was related higher to early retirement than diagnosed diseases. In the multivariate model, having ‘Diagnosed disease’ was not significantly related to whether older workers thought they could not work beyond 65 years of age. A bad ‘Self-rated health’ was also more highly related to whether older workers thought they could not work beyond 65 years, than if the respondents stated that a ‘Diagnosed disease is a hindrance in my daily work’ in the multivariate model. Conclusion This study showed an important difference between older workers’ own experiences and the effect of their self-rated health and their diagnosed diseases. Subjective self-rated health seems to be more important to people’s retirement

One hundred fifty 45-55-year-old men were divided into three groups: those with healthy backs, recurrent low back pain (LBP), and chronic LBP. These groups were studied with respect to anthropometry, spinal canal width, spinal sagittal configuration and flexibility, and the flexibility of the hamstrings musculature with straight leg raising (SLR). There were no differences between the groups with respect to anthropometry. The group with healthy backs had significantly greater lordosis and sagittal flexibility than the other groups. The width of the spinal canal was correlated to body height. The SLR test showed significantly higher values in the group with healthy backs and in the recurrent pain group than in the chronic pain group. The possible role of restoring normal range of motion to minimize the risk of LBP recurrence is discussed.

With the aim of assessment of 10 year risk of myocardial infarction (MI) development in men in dependence on stress at work place and in the family in a framework of the WHO program "MONICA-PSYCHOSOCIAL" we examined random representative sample of men (n=657) aged 25-64 years inhabitants of one of districts in Novosibirsk. During 10 years (1994-2004) we registered all cases of MI. For assessment of relative risk of MI development we used COX proportional regression model. Among men with first MI 47.4% had high level of stress in the family and 57.9% were subjected to stress at work place. Five and 10 year risk of MI in men with high test levels of stress at home and work place was 2-5 times greater than in those without. Among men subjected to stress in the family MI risk was the highest at age 55-64 years, while permanent stressful situations at work place were more common in age group 45-54 years. Among men with high levels of stress in the family and at work place higher rate of MI development was observed in widowers, divorced men with incomplete high or elementary education, heavy or moderate manual labor workers, and pensioners. The results indicate that critical life events as well as chronic stressful influences increase risk of MI among men aged 25-64 years. The group of greatest risk - middle and old age persons who are less protected against social, political and economical disbalance in the society.

Medical demography and the practice of medicine will be influenced by the personal plans of GPs and their decisions to stop practicing in the coming years. This study aims to understand the events that could potentially worsen the medical demography in terms of shortages of GPs for primary care in the short term. 455 GPs (all aged over 55 years) practicing in three districts of western France were selected to participate in this prospective study. 258 valid and complete questionnaires (56%) were received. With the use of a special programme, SPSS version 1.5, an overall comprehensive analysis and one by geographical sub-regional groups were performed. When queried about their plans or wishes for their practice between the present time and their age of 65, of the responding physicians, 27% wanted to continue working under the same conditions, 10% were undecided, and 63% wanted to stop or adjust their professional activity before age 65. The main reasons and factors motivating these plans were their current time constraints, the workload related to administrative tasks and the continuity of care; moreover, GPs noted the demands and expectations of patients, professional burnout and difficulties in obtaining a healthy work-life balance as factors contributing to these plans. Physicians who wanted to stop practicing (30%) were the least satisfied with their work and seem to have anticipated this plan of action given that they reduced their number of hours in the office and on-call. Those who wish to adapt their work time (33%) are for the most part satisfied even if they work more, but 70% want to reduce their work hours. The impact of these projects is a potentially heavy one, especially since two of the counties concerned have a low medical density and high rate of practicing physicians. Government measures currently proposed do not seem to respond to the evolution of private practice expected by GPs over 55 years.

Reliable production of copper-64 ({sup 64}Cu) was achieved by irradiating enriched nickel-64 ({sup 64}Ni, >94.8%) in an IBA 18/9 cyclotron. Nickel-64 (19.1 {+-} 3.0 mg) was electroplated onto an Au disc (125{mu}m Multiplication-Sign 15mm). Targets were irradiated with 11.7 MeV protons for 2 hours at 40{mu}A. Copper isotopes ({sup 60,61,62,64}Cu) were separated from target nickel and cobalt isotopes ({sup 55,57,61}Co) using a single ion exchange column, eluted with varying concentration of low HCl alcohol solutions. The {sup 64}Ni target material was recovered and reused. The {sup 64}Cu production rate was 1.46{+-}0.3MBq/{mu}A.hr/mg{sup 64}Ni(n = 10) (with a maximum of 2.6GBq of {sup 64}Cu isolated after 2hr irradiation at 40uA. Radionuclidic purity of the {sup 64}Cu was 98.7 {+-} 1.6 % at end of separation. Cu content was < 6mg/L (n = 21).

Pollack, Daniel

2018-01-01

A 55-year-old man with poliomyelitis presented with a plantarflexed foot and painful ulceration of the sub-first metatarsophalangeal joint present for many years. A two-stage procedure was performed to bring the foot to 90°, perpendicular to the leg, and resolve the ulceration. The first stage corrected only soft-tissue components. It involved using a hydrosurgery system to debride and prepare the ulcer, a unilobed rotational skin plasty to close the ulcer, and a tendo Achillis lengthening to decrease forefoot pressure. The second stage corrected the osseous deformity with a dorsiflexory wedge osteotomy of the first metatarsal. The ulceration has remained closed since the procedures, with complete resolution of pain.

The aim of this study was to examine measurement equivalence of the newly developed Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55) across age, sex, and time in a representative sample of children with newly diagnosed epilepsy. Data come from 373 children enrolled in the Health-related Quality of Life in Children with Epilepsy Study (HERQULES), a multisite prospective cohort study. Measurement equivalence was examined using a multiple-group confirmatory factor analysis framework, whereby increasingly stringent parameter constraints are imposed on the model. Comparison groups were stratified based on age (4-7 years vs. 8-12 years), sex (male vs. female), and time (measurement of health-related quality of life at diagnosis vs. 24 months later). The QOLCE-55 demonstrated measurement equivalence at the level of strict invariance for each model tested--age: χ(2) (3,123) = 4,097.3, p QOLCE-55 are perceived similarly among groups stratified by age, sex, and time and provide further evidence supporting the validity of the scale in children with epilepsy. Health professionals and researchers should be confident that group comparisons made using the QOLCE-55 are unbiased and that any group differences detected are meaningful; that is, not related to differences in the interpretation of items by informants. Future research replicating these findings is encouraged. Wiley Periodicals, Inc. © 2016 International League Against Epilepsy.

Data from National Health and Nutrition Examination Survey for 1999-2012 were used to evaluate factors that affect observed levels of blood cadmium (BCd) and urine cadmium (UCd) among former and current smokers aged 20-64 and ≥65 years. Adjusted levels (AGM) for BCd and UCd were higher among females as compared to males. The order of AGM for BCd by race/ethnicity for 20-64 years old was non-Hispanic white (NHW) non-Hispanic black (NHB) and NHW > NHB for ≥65 years old. The order of AGMs for UCd for 20-64-year-old current smokers was NHW > NHB and NHW > NHB for former smokers. For 20-64-year-old current smokers, exposure to environmental tobacco smoke at home was associated with higher levels of BCd. Levels of both UCd and BCd increased with age, but the rate of increase was as much as seven times higher among ≥65 years old than 20-64 years old. For current smokers, the number of cigarettes smoked inside home was positively associated with the levels of BCd. For current smokers aged 20-64 years, the number of cigarettes smoked inside home was positively associated with the levels of UCd (p smoked every day on the days they were smoked was also positively associated with the levels of UCd (p smokers, levels of both UCd and BCd were positively associated (p smoked per day at the time of quitting smoking and negatively associated with the time since smoking was quitted (p < 0.01).

To study the presence of personality disorder in cases of deliberate self harm (DSH) in young (15-24 years) and elderly (45-74 years) and compare. Deliberate self harm cases admitted in Medical and surgical departments and cases attending psychiatry department of R.G. Kar Medical College, Kolkata were studied. For diagnosis of personality disorder ICD 10 International Personality Disorder Examination (IPDE) questionnaire was used. Percentage of elderly patients having personality disorder (64%) was higher compared to young DSH patients (58.5%). In young group, most common disorder was emotionally unstable personality disorder (28.6%) and in elderly group most common was anankastic type of personality disorder (36%). Schizoid, dissocial, histrionic, and anxious-avoidant personality disorders were found in small percentages of cases. Among DSH patients, the most common personality disorder found in young age was Emotionally unstable (Impulsive and Borderline) personality disorder, but most common personality disorder found in elderly patients was Anankastic personality disorder.

The lifetime erythemal UV exposures received by selected population groups in south-east Queensland from birth up to an age of 55 years have been quantitatively estimated. A representative sample of teachers and other school workers received (64±22)x10 5 J m -2 to the neck compared with (4.1±1.4)x10 5 Jm -2 to the upper leg. A sample of indoor workers (bank officers, solicitors and psychologists) received approximately 2% less and a sample of outdoor workers (carpenters, tilers, electricians and labourers) received approximately 10% more to the neck than the school workers. These differences in erythemal UV exposures may influence the risk of non-melanoma skin cancer. (author)

2016-12-01

Full Text Available DNS64 and NAT64 are IPv6 transition technologies enabling IPv6 only clients to communicate with IPv4 only servers. Mtd64-ng is a novel DNS64 implementation, being a successor of MTD64. In this paper, the performance of mtd64-ng is compared with that of MTD64 and BIND. The details of the measurements are fully disclosed. It is found that under heavy load conditions mtd64-ng can answer six times as many “AAAA” record requests per second than BIND. Mtd64-ng fixed two issues of MTD64 and also outperformed its predecessor by answering 46% more “AAAA” record requests per second under heavy load conditions.

Full Text Available Abstract Background Sexual difficulties (SD are common among men of all ages and can have considerable impact on quality of life and indications for future health. SD are associated with mental and physical wellbeing and with relationship satisfaction, yet they are rarely discussed with medical professionals who are often ill equipped to assess and manage them. This paper provides an updated overview on the status of SD in Australian men from 18 to 55 years of age and will form a baseline comparison for future analyses of SD based on Ten to Men data. Methods We used data from Ten to Men, the Australian Longitudinal Study on Male Health. SD was measured using eight items capturing specific sexual difficulties. We examined associations of a range of health and lifestyle factors (smoking, alcohol consumption, illicit drug use, obesity and new sexual partners, self-rated health status, disability, pain medication, diagnosed physical and mental health conditions with each SD using logistic regression. The sample included 12,636 adult males who had previously been sexually active. Analysis was stratified by age (18–34 years versus 35–55 years. Results This paper shows that experiencing SD is relatively common among Australian men – overall half the sample (54 %; 95 % CI: 0.53–0.55 experienced at least one SD for more than 3 months over the past 12 months. While more common in older men aged 45 to 55 years, almost half the 18 to 24 year old men (48 % also reported at least one SD highlighting that SD affects men of all ages. We found that SDs were associated with both lifestyle and health factors, although the strongest associations were observed for health factors in both age groups, in particular poor self-rated health, having a disability and at least one mental health condition. Lifestyle factors associated with SDs in men of all ages included smoking, harmful alcohol consumption and drug use in the past 12 months. Obesity was

2017-06-01

Full Text Available Objective: The aim of this study is to investigate if neutrophil CD64 expression in febrile neutropenia patients could be used as an early indicator of bacteremia. Materials and Methods: All consecutive patients older than 18 years of age who had developed febrile neutropenia episodes due to hematological malignancies were included in the study. Those patients who had significant growth in their blood cultures constituted the case group, while those who had febrile neutropenia without any growth in their cultures and who did not have any documented infections formed the control group. Blood culture bottles were incubated in the Bact ALERT 3D system (bioMerieux, France, identification and susceptibility testing were performed using an automated broth microdilution method (VITEK 2, bioMerieux, and CD64 expression analysis was performed by the flow cytometry method. C-reactive protein (CRP was measured by turbidimetric methods (Biosystems, Spain and erythrocyte sedimentation rate (ESR was measured by the Wintrobe method. Results: In total, we prospectively evaluated 31 febrile episodes. The case group consisted of 17 patients while the control group included 14 patients. CD64 was found on neutrophils of the case group patients with a mean count of 8006 molecules/cell and of control group with a mean count of 2786 molecules/cell. CD64 levels of the case group were significantly higher than those of the control group (p=0.005. In the differentiation of the case group from the control group, a 2500 cut-off value for CD64 had significant [AUC=0.792 (0.619-0.965] predictive value (p=0.001. In the prediction of patients with a 2500 cut-off value for CD64, sensitivity was 94.1%, positive predictive value was 76.2%, specificity was 64.3%, and negative predictive value was 90.0%. CRP levels and ESR values did not differ significantly between the groups (p=0.005. Conclusion: Neutrophil CD64 expression could be a good predictor as an immune parameter with

The validation of a French-language version of the Aging Perceptions Questionnaire (APQ) and its extension to a population aged 55 and over

AbstractBackgroundSeveral studies have shown the influence of the perceptions of aging on the cognitive functioning and the mental and physical health of older people. These relationships have not to date been studied in France where validated instruments are lacking. The primary objective of this study was to validate a French-language version of the Aging Perceptions Questionnaire (APQ) in the French general population aged 65 and over. The secondary objective was to study the stability of the dimensions of this instrument among participants aged 55 to 64.MethodsThe study was proposed to the cohort of the Observatoire Régional du Vieillissement (OPREVI) (observatory of aging), located in a small town in Poitou-Charentes (western France). An anonymous questionnaire including the APQ was sent by mail to inhabitants aged 55 and over. The original English language APQ was described with adults aged 65 and older. It has 32 items distributed on 7 dimensions: timeline chronic and cyclical, positive and negative consequences, positive and negative control and emotional representations.Results656 adults participated in this survey (286 men, 370 women). Among those aged 65 and over (n = 394), the seven-factor structure estimated by confirmatory factor analysis was coherent with original findings. Internal consistency as evaluated by Cronbach alpha, was between 0.83 for consequences negative and 0.52 for control negative. Several dimensions were strongly correlated. Among participants aged 55 to 64 (n = 262), the same factorial model yielded an acceptable fit. Multi-group confirmatory factor analysis concluded to approximate factorial invariance between the two age groups with a null delta in comparative fit index.ConclusionThis study among French people aged 65 and over, added further evidence of the multidimensional structure of the French version of the APQ which is superimposed to the dimensions of the original Irish version. The same factorial structure

Full Text Available Background. Recent studies showed that depression was an independent predictor of mortality from cardio-vascular disease in healthy women. Objective. To explore the effect of depression (D on relative risk (RR of myocardial infarction (MI and stroke for 16 years (1995–2010 in the female population aged 25–64 years from Novosibirsk, Russia. Materials and methods. Under the third screening of the WHO “MONICA-psychosocial” (MOPSY programme, a cohort of women aged 25–64 years (N=560 was surveyed. Women were followed for 16 years for the incidence of MI and stroke (1995–2010. D was measured at the baseline examination by means of test “MOPSY”. Participants having stroke, MI, arterial hypertension, coronary artery diseases and diabetes in their medical history at the baseline were excluded from this analysis. Results. The prevalence of D in women aged 25–64 years was 55.2%. With the growth of D levels, positive self-rated health reduced and almost 100% of those women have complaints about their health, but considered the care of their health insufficient. Women with major D significantly extended negative behavioural habits: smoking and unsuccessful attempts to give up, low physical activity, and less likely to follow a diet (healthy food. Major D associated with high job strain and family stress. Relative risk (RR of MI development in women with D during 16 years of study was higher in 2.53 cases (p<0.05 and risk of stroke was higher in 4.63 cases (p<0.05. Conclusions. The prevalence of D in women aged 25–64 years was >50%. Women with D had a 2.53-fold risk of MI and 4.63-fold risk of stroke during the 16 years of follow-up.

Maternal-infant relationship quality and risk of obesity at age 5.5 years in a national US cohort

Science.gov (United States)

2014-01-01

Background Poor quality relationships between mothers and toddlers have been associated with higher risk for childhood obesity, but few prospective studies of obesity have assessed maternal-child relationship quality in infancy. In addition it is not known whether the increased risk is associated with the mother’s or the child’s contribution to the relationship quality. Methods We analyzed data (n = 5650) from the Early Childhood Longitudinal Study, Birth Cohort, a national study of U.S. children born in 2001 and followed until they entered kindergarten. At 9 months of age, the Nursing Child Assessment Teaching Scale (NCATS) was used to assess the quality of observed playtime interactions between mothers and infants, yielding separate scores for maternal and infant behaviors. Obesity (BMI ≥95th percentile) at age 5.5 years was based on measured weight and height. Results The prevalence (95% confidence interval) of obesity at 5.5 years of age was higher among children in the lowest quartile of maternal NCATS score (20.2% [95% CI: 17.2%, 23.2%]) than in the highest quartile (13.9% [11.3%, 16.5%]), but maternal NCATS score was not significantly associated with obesity after adjustment for race/ethnicity, maternal education and household income. The prevalence of obesity at 5.5 years of age was similar among children in the lowest quartile of infant NCATS score (17.4% [14.4%, 20.3%]) and in the highest quartile (17.6% 14.4%, 20.8%]), and was not changed with covariate adjustment. Conclusions Maternal-infant relationship quality, assessed by direct observation at 9 months of age in a national sample, was not associated with an increased risk of obesity at age 5.5 years after controlling for sociodemographic characteristics.

Full Text Available Abstract Background Symptom prevalence is generally believed to increase with age. The aim of this study was to evaluate the age specific prevalence of 30 general symptoms among Swedish middle-aged women. Methods A cross-sectional postal questionnaire study in seven Swedish counties in a random sample of 4,200 women 35–64 years old, with 2,991 responders. Thirty general symptoms included in the Complaint Score subscale of the Gothenburg Quality of Life Instrument were used. Results Four groups of age specific prevalence patterns were identified after adjustment for the influence of educational level, perceived health and mood, body mass index, smoking habits, use of hormone replacement therapy, and use of other symptom relieving therapy. Only five symptoms (insomnia, leg pain, joint pain, eye problems and impaired hearing increased significantly with age. Eleven symptoms (general fatigue, headache, irritability, melancholy, backache, exhaustion, feels cold, cries easily, abdominal pain, dizziness, and nausea decreased significantly with age. Two symptoms (sweating and impaired concentration had a biphasic course with a significant increase followed by a significant decrease. The remaining twelve symptoms (difficulty in relaxing, restlessness, overweight, coughing, breathlessness, diarrhoea, chest pain, constipation, nervousness, poor appetite, weight loss, and difficulty in urinating had stable prevalence with age. Conclusion Symptoms did not necessarily increase with age instead symptoms related to stress-tension-depression decreased.

Full Text Available Introduction: Adult individuals in Indonesia showed changes in diet and lack of physical activity, therefore increasing the risk of hypercholesterolemia and obesity. One of nutritional therapy for hypercholesterolemia is rice bran oil, which contains active substances that works synergistically in controlling lipid profile. The substances are gamma-orzanol, phytosterols, and vitamin E isomers (tocotrienol and tocopherol. Methods: A clinical trial was conducted for 4 weeks in City Hall of Jakarta on 20 males, age 19–55 years old, with mild-moderate hypercholesterolemia, to assess lipid profile improvement of the supplementation of rice bran oil 45 ml/days compared to 15 ml/days without changing eating patterns. Results: After 4 weeks of intervention, there was significant difference in total cholesterol level between both groups (p = 0.049. In the group that received 45 ml/days of rice bran oil, total cholesterol level decreased 14%, and in the group of 15 ml/days total cholesterol level decreased 7.8%. The reduction of LDL and triglycerides and the increase of HDL were not significantly different between both groups (p >0,05. There was no significant changes of body weight in both groups. Conclusion: This study showed that consumption of  45 ml/days rice bran oil led to better improvements in lipid profiles compare to 15 ml/days. It has been demonstrated that gamma oryzanol and plant sterols in rice bran oil have the capability to remove cholesterol from bile salt micelles, thus decreasing cholesterol absorption in intestine.

The aim of this article is to describe the potential with respect to volunteer work among 55 to 70-year-old persons along with a two-dimensional typology (actual volunteer work and intention of volunteering or expanding actual volunteer work) and to identify the influencing factors. Based on the dataset from the transitions and old age potential (TOP) study, a total of 4421 men and women born between 1942 and 1958 were included. A multinomial regression model showed the predictors for group affiliation along with an engagement-related typology (internal, utilized and external volunteer potential as well as definite non-volunteers). More than a half of the persons in the study sample could be classified as internal or external volunteer potential. Volunteers and potential volunteers revealed more similarities regarding resources and social factors than potential volunteers and definite non-volunteers. Potential volunteers were more active in other informal fields of activity (e.g. nursing or child care) than definite non-volunteers. With respect to volunteer work, definite non-volunteers showed various social disadvantages (in particular with respect to education and health) compared to (potential) volunteers. Other informal activities did not seem to be in major conflict with volunteer activities, e.g. nursing or child care, as long as they were carried out with moderate or low intensity.

Routine influenza vaccination is currently recommended in several countries for people aged more than 60 or 65 years or with high risk of complications. A lower age threshold of 50 years has been recommended in the United States since 1999. To help policymakers consider whether such a policy should be adopted more widely, we conducted an economic evaluation of lowering the age limit for routine influenza vaccination to 50 years in Brazil, France, Germany, and Italy. The probabilistic model was designed to compare in a single season the costs and clinical outcomes associated with two alternative vaccination policies for persons aged 50 to 64 years: reimbursement only for people at high risk of complications (current policy), and reimbursement for all individuals in this age group (proposed policy). Two perspectives were considered: third-party payer (TPP) and societal. Model inputs were obtained primarily from the published literature and validated through expert opinion. The historical distribution of annual influenza-like illness (ILI) incidence was used to simulate the uncertain incidence in any given season. We estimated gains in unadjusted and quality-adjusted life expectancy, and the cost per quality-adjusted life-year (QALY) gained. Deterministic and probabilistic sensitivity analyses were conducted. Comparing the proposed to the current policy, the estimated mean costs per QALY gained were R$4,100, EURO 13,200, EURO 31,400 and EURO 15,700 for Brazil, France, Germany, and Italy, respectively, from a TPP perspective. From the societal perspective, the age-based policy is predicted to yield net cost savings in Germany and Italy, whereas the cost per QALY decreased to R$2800 for Brazil and EURO 8000 for France. The results were particularly sensitive to the ILI incidence rate, vaccine uptake, influenza fatality rate, and the costs of administering vaccination. Assuming a cost-effectiveness threshold ratio of EURO 50,000 per QALY gained, the probabilities of the

Stroke is a leading cause of long-term disability and the fifth leading cause of death in Israel. Knowledge of stroke warning signs has been linked to early seeking of medical help. Little is known about knowledge of stroke warning signs in Israeli Jewish adults. Stroke knowledge was examined among Jewish Israeli adults. Using a structured questionnaire, registered nurses interviewed a convenience sample of the respondents, 18 years or older, with no stroke history. Stroke knowledge and demographics were examined by 3 age groups (64 years) in men and women. In total, 1137 Jewish Israelis were interviewed, 457 (40.2%) men and 680 women (59.8%); 493 (43.4%) were younger than 45 years, 541 (47.6%) were aged 45 to 64 years, and 102 (9%) were older than 64 years; 1 (0.1%) did not report age. On average, each interview lasted for 25 to 30 minutes. Participants younger than 45 years showed the lowest knowledge of stroke cause. Women younger than 45 years were less likely to identify at least 2 stroke warning signs. Participants younger than 45 years were less likely to identify at least 2 risk factors, compared with participants aged 45 to 64 years and older than 64 years. Women younger than 45 years were less likely to identify at least 2 stroke prevention strategies. Participants younger than 45 years showed the lowest levels of stroke knowledge. The highest stroke knowledge was found in the 45 to 64 years age group. Stroke knowledge among different age groups was similar in both genders. Educational campaigns aimed at increasing knowledge of stroke among the general population and targeting the younger population are recommended.

Statin use is associated with a variety of overtly related muscle symptoms including muscle pain, myalgia, creatine kinase elevations without pain with myolysis and myositis (rhabdomyolysis), a potentially fatal side effect that led to the withdrawal of cerivastatin in 2001. Unintended drug response phenotypes have an impact on patient compliance and sometimes patient health and the assessment of risk on an individual basis could enhance therapeutic benefit. We therefore investigated whether common single nucleotide polymorphisms were associated with the expression of broadly grouped atorvastatin-induced muscle events in a case-control study (n=263 samples, n=388 SNPs). Of a number of associations identified in a discovery sample (51 atorvastatin-induced muscle and 55 normal) only those corresponding to the CYP2D6*4 allele were significantly associated in the sample (24 atorvastatin-induced muscle and 133 normal) (Discovery P=0.004, odds ratio=3.6; Validation P=0.036, odds ratio=2.7; total P=0.001, odds ratio=2.5). The frequency of the CYP2D6*4 allele was about 50% in atorvastatin-induced muscle patients but only 28% in controls, similar to that of other patient types (28.5%). The association was independent of various demographic variables and not explained by gross demographic, clinical or population-structure differences among cases and controls. Surprisingly, the CYP2D6*4 allele appeared similarly distributed among controls and patients expressing simvastatin-induced muscle events (n=169, frequency in case participants=49.2%, P=0.067, odds ratio=1.7). Our results suggest that the CYP2D6*4 allele is associated with broadly related muscle events caused by at least two structurally dissimilar HMG-CoA reductase inhibitors, and as such, may have implications for a better understanding of this statin-wide phenomena.

Prediabetes is an independent risk factor for cardiovascular disease. However, data on the long term adverse clinical outcomes of prediabetic patients undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) are scarce. The study population comprised 674 consecutive non-diabetic patients who underwent elective PCI between April 2007 and November 2010. Prediabetes was defined as hemoglobin A1c (HbA1c) of 5.7% to 6.4%. Two-year cumulative clinical outcomes of prediabetic patients (HbA1c of 5.7% to 6.4%, n=242) were compared with those of a normoglycemic group (prediabetes group. There was no significant difference between the two groups in coronary angiographic parameters, except for a higher incidence of diffuse long lesion in the prediabetes group. For prediabetic patients, trends toward higher incidences of binary restenosis (15.6% vs. 9.8 %, p=0.066) and late loss (0.71±0.70 mm vs. 0.59±0.62 mm, p=0.076) were noted. During the 24 months of follow up, the incidence of mortality in prediabetic patients was higher than that in normoglycemic patients (5.5% vs. 1.5%, p=0.007). In our study, a higher death rate and a trend toward a higher incidence of restenosis in patients with prediabetes up to 2 years, compared to those in normoglycemic patients, undergoing elective PCI with contemporary DESs. © Copyright: Yonsei University College of Medicine 2018.

Full Text Available Introduction: Ischemic heart disease and cerebrovascular disease are two of the major health problems at present, dyslipidemia is one of the major vascular risk factors modifiable. Since 2009 the Ministry of Health of Uruguay to care promoted the participation of "Medical Reference", especially in the 45 to 64 years. This care is a goal to achieve by the IAMC in Uruguay, which results in a payment to the institutions achieve compliance. It is in our interest to know the prevalence of dyslipidemia in this age group and association with other vascular risk factors. A study in 2009 found a prevalence CUDAM of dyslipidemia reported 25% in this age range. Objectives: 1 Determine the prevalence of dyslipidemia among users 45 to 64 of CUDAM assisted by their referring physician. 2 To determine the percentage of patients who know their dyslipidemia and the degree of compliance with medical therapy. 3 To evaluate the association with other vascular risk factors defined. Methods: 454 patients between 45 and 64 years attended between 01/07 and 31/12/10 by the referring doctor with lipid profile. We conducted a telephone survey to find the presence of dyslipidaemia, treatment, compliance and associated vascular risk factors. Results: 454 patients with lipid profiles, mean cholesterol levels of 211 mg / dl. 25% and 18.9% of patients have LDL levels of cholesterol and triglycerides respectively the reference value. 56% reported having dyslipidemia for interrogation, of which 26% had normal levels of LDL and triglycerides. Discussion: In these patients, the prevalence of dyslipidemia and vascular risk factors consistent with the literature further analyzed. The need to be controlled by your referring doctor raised the level of detection and dyslipidemic patients' knowledge of CUDAM.

For severely obese patients, bariatric surgery has been recommended as an effective therapy. The Bariataric Surgery and Education (BaSE) study aimed to assess the efficacy of a videoconferencing-based psychoeducational group intervention in patients after bariatric surgery. The BaSE study is a randomized, controlled multicenter clinical trial involving 117 patients undergoing bariatric surgery (mean preoperative body mass index [BMI] 49.9 kg/m(2), SD 6.4). Patients were enrolled between May 2009 and November 2012 and were randomly assigned to receive either conventional postsurgical visits or, in addition, a videoconferencing-based 1-year group program. Primary outcome measures were weight in kilograms, health-related quality of life (HRQOL), and general self-efficacy (GSE). Secondary outcome measures were depression symptoms and eating behavior. 94% of the patients completed the study. Mean weight loss for all patients was 45.9 kg (SD 16.4) 1 year after surgery (mean excess weight loss [EWL] 63%). Intention-to-treat analyses revealed no differences in weight loss, EWL, HRQOL, or self-efficacy between study groups at 1 year after surgery. However, patients with clinically significant depression symptoms (CSD) at baseline assigned to the intervention group (n = 29) had a significantly better HRQOL (P = .03), lower depression scores (P = .02), and a trend for a better EWL (.06) 1 year after surgery compared with the control group (n = 20). We could not prove the efficacy of the group program for the whole study sample. However, results indicate that the intervention is effective for the important subgroup of patients with CSD.

The incidence of osteoporosis increases with age and is most frequently observed in postmenopausal women. The objective of the present population-based cohort study was to assess the influence of Ca intake from dairy sources on hip bone mineral density and hip fracture incidence in a group of Polish women over 55 years of age. The main outcome measures included: bone mineral density, the number of previous fractures and the reported Ca intake from dairy sources, assessed by a diet questionnaire. The RAC-OST-POL Study was conducted in the District of Raciborz in the south of Poland. The study was carried out in a group of 625 women, randomly recruited from the general population of women aged >55 years. Median Ca intake from dairy products was lower in the group of women with femoral neck T-score ≤-2·5 than in the group with T-score >-2·5 (275 v. 383 mg/d; P = 0·0019). For total hip score, the difference was close to borderline significance (P = 0·0698). Median Ca intake from dairy products was lower in the group of women with previous fractures than in those without fracture history (336 v. 395 mg/d; P = 0·0254). The main dairy source of Ca in the analysed group included milk drinks, rennet cheese and milk. Higher dairy Ca intake is recommended, since a number of the women analysed were unable to satisfy their Ca requirement exclusively from their diet.

Cancerogenesis Risks between 64 and 320 Row Detector CT for Coronary CTA Screening

Full Text Available Objectives: This study compares cancerogenesis risks posed by the 64 row detector and the 320 row detector computed tomography scanners used during coronary computed tomography angiography (CCTA following decennial screening guidelines. Material and Methods: Data of the radiation absorbed after CCTA by lung, thyroid, and female breast in patients between 50 and 70 years of age obtained from prior published literature for the 64 row CT scanner were compared with data from our study using 320 row detector CT scanner. Data from the 64 row and the 320 row detector CT scanners was used to determine lifetime attributable risks (LAR of cancer based on the biological effects of ionizing radiation (BEIR VII report. Results: The relative reduction of LAR (% for 50-, 60-, and 70-year-old patients undergoing scanning with the 320 row detector CT scanner was 30% lower for lung, and more than 50% lower for female breast when compared with results from 64 row detector CT scanner. The use of 320 row detector CT would result in a combined cumulative cancer incidence of less than 1/500 for breast in women and less than 1/1000 for lung in men; By comparison, this is much lower than other more common risk factors: 16-fold for lung cancer in persistent smokers, 2-fold for breast cancer with a first degree family member history of breast cancer, and 10-fold for thyroid cancer with a family member with thyroid cancer. Decennial screening would benefit at least 355,000 patients from sudden cardiac death each year, 94% of whom have significant coronary artery disease, with at least one stenosis >75%. LAR for thyroid cancer was negligible for both scanners. Conclusion: Lung and female breast LAR reductions with 320 row detector compared with 64 row detector CT are substantial, and the benefits would outweigh increased cancer risks with decennial screening in the age group of 50-70 years.

Work life expectancy (WLE) expresses the expected time a person will remain in the labor market until he or she retires. This paper compares a life table approach to estimating WLE to an approach based on multi-state proportional hazards models. The two methods are used to estimate WLE in Danish members and non-members of an early retirement pensioning (ERP) scheme according to levels of health. In 2008, data on self-rated health (SRH) was collected from 5212 employees 55-65 years of age. Data on previous and subsequent long-term sickness absence, unemployment, returning to work, and disability pension was collected from national registers. WLE was estimated from multi-state life tables and through multi-state models. Results from the multi-state model approach agreed with the life table approach but provided narrower confidence intervals for small groups. The shortest WLE was seen for employees with poor SRH and ERP membership while the longest WLE was seen for those with good SRH and no ERP membership. Employees aged 55-56 years with poor SRH but no ERP membership had shorter WLE than employees with good SRH and ERP membership. Relative WLE reversed for the two groups after age 57. At age 55, employees with poor SRH could be expected to spend approximately 12 months on long-term sick leave and 9-10 months unemployed before they retired - regardless of ERP membership. ERP members with poor SRH could be expected to spend 4.6 years working, while non-members could be expected to spend 7.1 years working. WLE estimated through multi-state models provided an effective way to summarize complex data on labor market affiliation. WLE differed noticeably between members and non-members of the ERP scheme. It has been hypothesized that while ERP membership would prompt some employees to retire earlier than they would have done otherwise, this effect would be partly offset by reduced time spent on long-term sick leave or unemployment. Our data showed no indication of

2015-01-01

Allogeneic hematopoietic transplantation is increasingly used in patients aged 55 years or more with AML. The question of whether outcomes can be improved with an allele-level 8/8 HLA-matched unrelated donor (MUD) rather than an older HLA-matched sibling (MSD, more than 55 years) is still...... unanswered. We thus analyzed outcomes in 714 patients aged 55 years and older with AML in first CR (CR1) who received PBSCs after a reduced-intensity conditioning hematopoietic cell transplant from a MUD (n=310) or a MSD (n=404) in a recent period (2005-2010). The 3-year cumulative incidences (CIs) of non......-relapse mortality were 17% and 23% with MSD and MUD, respectively (P=0.17). The 3-year CIs of relapse were 37% and 30%, respectively (P=0.12), resulting in a 3-year CI of leukemia-free survival of 46% and 47%, respectively (P=0.51). The 3-year overall survival was 49% with both MSD and MUD. In conclusion, HLA...

"HIDROROUTE 55" Saving water is a recurrent topic for students in Spain because the Mediterranean zone suffers periodically severe droughts. Any student knows it and is able to repeat some basic advices like "take showers instead of baths, or "close the tap when brushing your teeth..." But maybe this is a quite superficial awareness about shortage and saving water. Where does the home flowing water come from? How can we be sure that this water is clean and safe to drink? And, tomorrow or next week, will be there water in our tap? Perhaps working in these questions is a good way to understand how difficult is to get water to our homes. In order to deepen in the question we are preparing a teaching unit titled "Hydro route 55: from the Earth to la Maurina trough the water" on 1rst ESO level students (12 years old) of the secondary public school "Institut les Aymerigues" in Terrassa (Barcelona). Students' tasks will be to search information about the way water gets to their homes, including water cycle, treatment and saving water... This unit belongs to an integrated project with all areas involved (history, mathematics, technology, languages and music) that aims to approach students to different aspects of their zone in Terrassa (La Maurina) and it will be implemented at the end of the second term, just some weeks before the Vienna's meeting. School and teaching team: Institut les Aymerigues is a new school that this year has only 1rst ESO students (12 years old). Teaching staff is engaged in developing an integrated and based on competences curriculum. In this context we integrate English and Science content in a unified teaching schedule of six hours per week for the students. One English teacher and two Science teachers are involved in it. In addition we have three student teachers from "Master of Secondary Teachers Training" that are in charge of preparing the Hydroroute 55 activities with the titular teachers. We illustrate students' tasks such as the

Health literacy is of increasing importance in public health research. It is a necessary pre-condition for the involvement in decisions about health and health care and related to health outcomes. Knowledge about limited health literacy in different age groups is crucial to better target public health interventions for subgroups of the population. However, little is known about health literacy in Germany. The study therefore assesses the prevalence of limited health literacy and associated factors among different age groups. The Health Literacy Survey Germany is a cross-sectional study with 2,000 participants aged 15 years or older in private households. Perceived health literacy was assessed via computer-assisted personal interviews using the HLS-EU-Q-47 questionnaire. Descriptive analyses, chi-square tests and odds ratios were performed stratified for different age groups. The population affected by limited perceived health literacy increases by age. Of the respondents aged 15-29 years, 47.3 % had limited perceived health literacy and 47.2 % of those aged 30-45 years, whereas 55.2 % of the respondents aged 46-64 years and 66.4 % aged 65 years and older showed limited perceived health literacy. In all age groups, limited perceived health literacy was associated with limited functional health literacy, low social status, and a high frequency of doctor visits. The results suggest a need to further investigate perceived health literacy in all phases of the life-course. Particular attention should be devoted to persons with lower social status, limited functional health literacy and/or a high number of doctor visits in all age groups.

Full Text Available Objectives: Falling down is one of the most common problems that involve old people. It may affect the physical, emotional and social aspects of individual’s health and may cause economical and social problems for individuals and society. Methods & Materials: In a cross sectional study, 750 old people with ages of 55 or more, living in the city of Shiraz (409 female, 341 male, mean ages 67.32 year with a convenience sampling method took part in this study. A questionnaire was designed to gather the information about the history of falling down on past year, its complications and the possible associated factors. Chi square and Mann_ Witeny test and logistic regression method was used to analyze the study data. Results: the prevalence of falling down was 33.6%. 20.4% of people had single falling down and 13.2% of them had recurrent falling down. There were significant correlations between falling down and age (P=0.016, sex (P<0.001, diabetes (P=0.008, vertigo (P<0.0001. However no significant correlation was found between falling down with arthritis, heart disease, nervous system disease, rheumatologic disease, hypertension and use of cane and glass. There were significant correlation between recurrent falling down and sex (P=0.021, vertigo (P<0.0001 and osteoporosis (P=0.024. Also, use of cane (P=0.023 and arthritis (P=0.048 were associated with falling down with injury. Conclusion: According to results of this study, one third of old people over 55 year living in the community experienced falling down within one year. Diabetes and vertigo increased the risk of falling down in elderly population. Planning for controlling these risk factors can reduce the rate of falling down and its associated problems and complications.

To quantify the poverty status and level of disadvantage experienced by Australians aged 45-64 years who have left the labour force due to diabetes in 2010. A purpose-built microsimulation model, Health&WealthMOD2030, was used to estimate the poverty status and level of disadvantage of those aged 45-64 years who prematurely retire from the workforce due to diabetes. A multiple regression model was used to identify significant differences in rates of income poverty and the degree of disadvantage between those out of the labour force due to diabetes and those employed full- or part-time with no diabetes. 63.9% of people aged 45-64 years who were out of the labour force due to diabetes were in poverty in 2010. The odds of being in poverty for those with no diabetes and employed full-time (OR of being in poverty 0.02 95%CI: 0.01-0.04) or part-time (OR of being in poverty 0.10 95%CI: 0.05-0.23) are significantly lower than those for persons not in the labour force due to diabetes. Amongst those with diabetes, those who were able to stay in either full- or part-time employment were as much as 97% less likely to be in poverty than those who had to retire early because of the condition. Sensitivity analysis was used to assess impacts of different poverty line thresholds and key socioeconomic predictors of poverty. This study has shown that having diabetes and not being in the labour force because of this condition significantly increases the chances of living in poverty. Intervening to prevent or delay the onset of diabetes is likely to improve their living standards.

Practical Evaluation of Stateful NAT64/DNS64 Translation

Directory of Open Access Journals (Sweden)

SKOBERNE, N.

2011-08-01

Full Text Available It is often suggested that the approach to IPv6 transition is dual-stack deployment; however, it is not feasible in certain environments. As Network Address Translation -- Protocol Translation (NAT-PT has been deprecated, stateful NAT64 and DNS64 RFCs have been published, supporting only IPv6-to-IPv4 translation scenario. Now the question of usability in the real world arises. In this paper, we systematically test a number of widely used application-layer network protocols to find out how well they traverse Ecdysis, the first open source stateful NAT64 and DNS64 implementation. We practically evaluated 18 popular protocols, among them HTTP, RDP, MSNP, and IMAP, and discuss the shortcomings of such translations that might not be apparent at first sight.

[Old and offline? : Findings on the use of the Internet by people aged 65 years and older in Switzerland].

The supply of information and communication is becoming continuously more focused on the Internet. While the age groups up to 64 years have shown a vast increase in the use of the Internet since 1997, intensive use of the Internet by age groups above 64 years lags behind and this is not only the case in Switzerland. Against this background and an interest in finding out more about Internet (non)use of older people, two representative surveys were conducted in Switzerland, one in 2009 and another one in 2014. The data used were acquired throughout Switzerland via a standardized telephone survey. The random sample (2014) consisted of 1037 people aged between 65 and 100 years old. Although the digital divide between the age groups has lessened over the past years, only 55.7 % of the elderly people interviewed were using the Internet in the autumn of 2014. Internet usage differs greatly between age groups. Resources such as education, income and health positively impact actual use of the Internet. Additionally, recommendations from a person's social environment, as well as an affinity for technology and a personal benefit assessment have a positive impact on Internet usage. In particular, security concerns and difficulties of use were mentioned as predominant reasons for the non-use of the Internet. Some of the people questioned felt excluded from society because they did not use the Internet. Internet usage among elderly people depends on individual and social resources, as well as on general attitude towards technology and personal benefit expectations. The exclusion of today's elderly "offliners" should be avoided, even if the digital divide will decrease in the future.

Describe the factors which can be associated with cognitive impairment in institutionalized and non-institutionalized elderly. Cross-sectional study of 200 people aged over 64 in Huelva (Spain) in 2014. Of these, 100 people were institutionalized in a residential facility and 100 were not. Cognitive impairment was assessed using the Mini-Mental State Examination (MMSE-35), basic activities of daily living by Barthel index, general health through the Goldberg GHQ-28 and social, clinical and behavioural variables were contemplated in the study. The association of cognitive impairment with all the variables was analysed using Chi-square test. Finally, a multivariate analysis was performed using logistic regression to identify possible joint influence of variables to study on the cognitive impairment. The prevalence of cognitive impairment in those institutionalized was 47%, higher than that of non-institutionalized group which was only 8% (p<.001). The dependence for basic activities for daily living and learning activities were the only variables in both groups which were associated with the cognitive impairment. Institutionalization (OR=5.368), age (OR=1.066) and dependence for basic activities (OR=5.036) were negatively associated with CI, while learning activities (OR=.227) were associated in a positive way. Conducting learning activities and the promotion of personal autonomy can delay cognitive impairment in older people. It is important to include cognitive stimulation programs aimed at the old population, especially in residential institutions. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

Worklife expectancy in a cohort of Danish employees aged 55–65 years - comparing a multi-state Cox proportional hazard approach with conventional multi-state life tables

Full Text Available Abstract Background Work life expectancy (WLE expresses the expected time a person will remain in the labor market until he or she retires. This paper compares a life table approach to estimating WLE to an approach based on multi-state proportional hazards models. The two methods are used to estimate WLE in Danish members and non-members of an early retirement pensioning (ERP scheme according to levels of health. Methods In 2008, data on self-rated health (SRH was collected from 5212 employees 55–65 years of age. Data on previous and subsequent long-term sickness absence, unemployment, returning to work, and disability pension was collected from national registers. WLE was estimated from multi-state life tables and through multi-state models. Results Results from the multi-state model approach agreed with the life table approach but provided narrower confidence intervals for small groups. The shortest WLE was seen for employees with poor SRH and ERP membership while the longest WLE was seen for those with good SRH and no ERP membership. Employees aged 55–56 years with poor SRH but no ERP membership had shorter WLE than employees with good SRH and ERP membership. Relative WLE reversed for the two groups after age 57. At age 55, employees with poor SRH could be expected to spend approximately 12 months on long-term sick leave and 9–10 months unemployed before they retired – regardless of ERP membership. ERP members with poor SRH could be expected to spend 4.6 years working, while non-members could be expected to spend 7.1 years working. Conclusion WLE estimated through multi-state models provided an effective way to summarize complex data on labor market affiliation. WLE differed noticeably between members and non-members of the ERP scheme. It has been hypothesized that while ERP membership would prompt some employees to retire earlier than they would have done otherwise, this effect would be partly offset by reduced time spent on

To describe the pattern of dental services provided to 64-65-year-old Danes who are regular users of dental care over a 5-year period, to analyse whether this pattern is associated with socio-demographic and/or socioeconomic factors, and if different uses of dental services are related to dental status and caries experience. Finally, to discuss the future planning of dental services aimed at the increasing population of elderly citizens. [Correction made on 21 March 2014, after first online publication: The sentence 'Data on elderly's dental service are scarce, although increased use is seen and more teeth are present in this age group.' was removed.] A cross-sectional study of all aged 64-65 (n = 37 234) who received a dental examination in 2009 was conducted. Clinical data comprised dental services received under the National Health Insurance reimbursement scheme, dental status and DMFT. Geographical, socio-demographic and socioeconomic data derived from public registers. Almost all received restorations, while periodontal treatment was received by dental services was dominated by periodontal services. Periodontal services were most prevalent in the capital and the most affluent areas. Relatively more extractions were related to low income and persons in least affluent areas. Total number of services was highest among women, persons with ≥20 teeth, persons living in the capital, and where the ratio user per dentist was low. For future planning of dental care for elderly, dental status, geographical and social area-based factors and to some degree gender, income, and education must be taken into consideration as all these factors seem to influence the future demand for dental services. © 2014 John Wiley & Sons A/S and The Gerodontology Association.

Full Text Available PURPOSE: To evaluate prospectively the results obtained in 55 patients undergoing laparoscopic pyeloplasty through transperitoneal access. MATERIALS AND METHODS: From January 2005 to July 2009, fifty-five patients between 13 and 64 years old, were treated for ureteropelvic junction (UPJ stenosis via a transperitoneal laparoscopy. All patients had clinical symptoms of high urinary obstruction and hydronephrosis confirmed by imaging methods. Anderson-Hynes dismembered pyeloplasty was performed in 51 patients and Fenger technique in the other 4 cases. Patients were clinically and imaging evaluated in the postoperative period at 3 and 6 months and then followed-up annually. RESULTS: The operative time ranged from 95 to 270 min. The mean hospital stay was 2 days. The average blood loss was 170 mL. The time to return to normal activities ranged from 10 to 28 days. Anomalous vessels were identified in 27 patients, intrinsic stenosis in 23 patients and 5 patients had high implantation of the ureter. Laparoscopic pyelolithotomy was successfully performed in 6 patients with associated renal stones. That series monitoring ranged from 1 to 55 months. One patient had longer urinary fistula (11 days, 3 patients had portal infection and 6 patients had prolonged ileus. There was one conversion due to technical difficulties. From the later postoperative complications, 2 patients had re-stenosis, one determined by Anderson-Hynes technique and the other by Fenger technique. The success rate was 95.65%. CONCLUSIONS: Laparoscopic pyeloplasty has functional results comparable to conventional open technique. It offers less morbidity, with aesthetic and post-operative convalescence benefits and lower complication rates.

2010-12-01

Management of CML has changed markedly since the introduction of tyrosine kinase inhibitors (TKIs). However stem cell transplantation (SCT) remains a valid therapeutic modality especially in developing countries due to its relatively lower cost. We aim to compare between imatinib mesylate and SCT as regard outcome in CML in the pediatric age group. Forty-eight patients with newly diagnosed CML in the chronic phase, aged 3 to 18 years were enrolled in this prospective study. Patients without a matched donor (Group I; N=30) were assigned to receive imatinib mesylate at a dose of 340mg÷m2÷day, while patients with a fully matched related donor (Group II; N=18), were offered SCT. Response (hematologic, cytogenetic and molecular), side effects and survival were analyzed. Complete hematologic response was obtained in 97% of the patients in group I and 94% in group II. Major cytogenetic response (CyR) was obtained in 80% of patients in group I and 100% in group II. Complete CyR was 57% in group I and 64% in group II. Major molecular response (MMR) was 36% in group I and 50% in group II with no significant difference between both groups. Six years overall survival (OS) was 87% in the 1st group and 61% in the 2nd group (pSCT group (55% had GVHD and 78% had infection). Imatinib mesylate has a superior OS and EFS than SCT in children. It is generally safe and well tolerated. Imatinib mesylate should be the 1st line treatment of pediatric patients with CML in the chronic phase. CML- Imatinib- SCT- Pediatrics.

Objective Approximately 70% of all US suicides are among working-age adults. This study was to determine whether and how 12-month suicidal ideation and suicide attempt were associated with specific occupations among currently employed adults aged 18–64 in the U.S. Methods Data were from 184,300 currently employed adults who participated in the 2008–2013 National Surveys on Drug Use and Health (NSDUH). NSDUH provides nationally representative data on suicidal ideation and suicide attempt. Descriptive analyses and multivariable logistic regressions were conducted. Results Among currently employed adults aged 18–64 in the U.S., 3.5% had suicidal ideation in the past 12 months (3.1% had suicidal ideation only, and 0.4% had suicidal ideation and attempted suicide). Compared with adults in farming, fishing, and forestry occupations (model adjusted prevalence (MAP) = 1.6%), adults in the following occupations were 3.0–3.6 times more likely to have suicidal ideation in the past year (model adjusted relative risks (MARRs) = 3.0–3.6): lawyers, judges, and legal support workers (MAP = 4.8%), social scientists and related workers (MAP = 5.4%), and media and communication workers (MAP = 5.8%). Conclusions Among employed adults aged 18–64 in the U.S., the 12-month prevalence of suicidal ideation varies by occupations. Adults in occupations that are at elevated risk for suicidal ideation may warrant focused suicide prevention. PMID:26995251

Davie, Gabrielle; Lilley, Rebbecca

2018-04-27

The study aims to quantify the impact of injury on the financial well-being of older workers. The hypothesis was that injured older workers have substantially reduced income from work following injury, but that New Zealand's (NZ) universal injury compensation scheme mitigates the difference for total income. An e-cohort of 617 722 workers aged 45-64 years old was created using de-identified linked administrative data in NZ's Integrated Data Infrastructure. Person-level data from numerous government agencies were used to compare 21 639 with an injury-related entitlement claim in 2009 with the remaining 596 133. Event date was the date of injury, or for the comparison group, a randomly selected date in 2009. Geometric mean ratios (GMRs) were used to compare income from work and total income from all taxable sources between those injured and the comparison group. Adjusted GMRs estimated income differences up to 36 months following the event date. Differences in total income increased over time. In the third year, those injured received 6.7% less (adjusted GMR 0.933 (95% CI 0.925 to 0.941)) than the comparison group, equivalent to an average loss of $NZ2628. Restricting to income from work, those injured received 29.2% less than the comparison group at 3 years (adjusted GMR 0.708 (95% CI 0.686 to 0.730)). For both men and women, those injured at 45-49 years consistently had the greatest relative income loss compared with those aged 50-54, 55-59 or 60-64 years. Although the substantial impacts of injury on income were mainly mitigated by public income transfers, relative losses in income in those aged 45-64 years increased in the 3 years following injury. Policies focused on adequate compensation and reducing the time away from employment could reduce these financial impacts in older workers. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Mihats, Daniela; Moche, Wolfgang; Prean, Michael; Rauscher-Gabernig, Elke

2015-05-01

The dietary exposure to the sum of the six indicator PCBs (Σ6 PCBs; PCB 28, 52, 101, 138, 153, and 180) across different Austrian population groups was assessed in this study by combining data on occurrence from food of the Austrian market (n=157) analysed during 2006-2011 with national food consumption data. The most contaminated food group was meat, poultry, game and offal with average levels of ndl-PCBs of 5.20 ng g(-1) fat. In fish and fish products and eggs, mean concentrations of 3.89 ng g(-1) fresh weight (fw) and 4.00 ng g(-1) fat, respectively, were found. In milk and dairy products average concentrations ranged from 3.07 to 4.44 ng g(-1) fat. The mean dietary intake of Σ6 PCBs was estimated to be 3.37 ng kg(-1) bw d(-1) for children (6-15 years old), 3.19 ng kg(-1) bw d(-1) for women (19-65 years) and 2.64 ng kg(-1) bw d(-1) for men (19-65 years). In all three population groups, milk and dairy products was the major contributing food group to the total dietary intake (50-55%) followed by fish and fish products (23-27%).

Highlights: • MWA appears to be a more effective treatment for larger tumors compared with RFA. • Intraoperative MWA outperformed percutaneous MWA. • Complications related to MWA of liver tumors were minor and self limited. - Abstract: Purpose: To retrospectively evaluate the safety and efficacy of microwave ablation (MWA) as treatment for single, focal hepatic malignancies. Materials and Methods: Institutional review board approval was obtained for this HIPAA-compliant study. From December 2003 to May 2012, 64 patients were treated with MWA for a single hepatic lesion, in 64 sessions. Hepatocellular carcinoma (HCC) was treated in 25 patients (geometric mean tumor size, 3.33-cm; 95% CI, 2.65–4.18-cm; range, 1.0–12.0-cm), metastatic colorectal cancer (CRC) was treated in 27 patients (geometric mean tumor size, 2.7-cm; 95% CI, 2.20–3.40-cm; range, 0.8–6.0-cm), and other histological-types were treated in 12 patients (geometric mean tumor size, 3.79-cm; 95% CI, 2.72–5.26-cm; range, 1.7–8.0-cm). Kaplan–Meier (K–M) method was used to analyze time event data. Chi-square and correlation evaluated the relationship between tumor size and treatment parameters. Results: Technical success rate was 95.3% (61/64). Treatment parameters were tailored to tumor size; as size increased more antennae were used (p < 0.001), treatment with multiple activations increased (p < 0.028), and treatment time increased (p < 0.001). There was no statistically significant relationship between time to recurrence and tumor size, number of activations, number of antennae, and treatment time. At one-year, K–M analysis predicted a likelihood of local recurrence of 39.8% in HCC patients, 45.7% in CRC metastases patients, and 70.8% in patients with other metastases. Median cancer specific survivals for patients were 38.3 months for HCC patients, 36.3 months for CRC metastases, and 13.9 months for other histological-types. Complications occurred in 23.4% (15/64) of sessions

Copper-64 Dichloride as Theranostic Agent for Glioblastoma Multiforme: A Preclinical Study

Full Text Available Glioblastoma multiforme (GBM is the most common primary malignant brain tumor in adults with a median survival time less than one year. To date, there are only a limited number of effective agents available for GBM therapy and this does not seem to add much survival advantage over the conventional approach based on surgery and radiotherapy. Therefore, the development of novel therapeutic approaches to GBM is essential and those based on radionuclide therapy could be of significant clinical impact. Experimental evidence has clearly demonstrated that cancer cells have a particularly high fractional content of copper inside the nucleus compared to normal cells. This behavior can be conveniently exploited both for diagnosis and for delivering therapeutic payloads (theranostic of the radionuclide copper-64 into the nucleus of cancerous cells by intravenous administration of its simplest chemical form as dichloride salt [64Cu]CuCl2. To evaluate the potential theranostic role of [64Cu]CuCl2 in GBM, the present work reports results from a preclinical study carried out in a xenografted GBM tumor mouse model. Biodistribution data of this new agent were collected using a small-animal PET tomograph. Subsequently, groups of tumor implanted nude mice were treated with [64Cu]CuCl2 to simulate single- and multiple-dose therapy protocols, and results were analyzed to estimate therapeutic efficacy.

To examine the validity of proxy-based NEO-Five Factor Inventory ratings for 18- to 64-year-old Chinese who attempted suicide. In all, 71 suicide attempters and their proxy-informants were recruited. Data based on structured interviews with the proxy respondents were compared with data obtained from interviews of the subjects themselves. For the 71 subject-proxy pairs, the overall correlations were fair to moderate (r = 0.30-0.45; p data that correlated less strongly with subjects' self-reports. Spousal ratings and self-reports correlated significantly in all domains, except extraversion (r = 0.42-0.63; p proxy-based data on NEO-Five Factor Inventory in research of suicidal behaviour in this age-group.

Full Text Available Objective: A growing interest in cellular targets of nutritional minerals and biochemical mechanisms has attracted the attentions of researchers towards their role in formation of obesity. However, there is no study investigating the effects of nutritional element levels of drinking water on body composition of the elderly. Therefore, we aimed to examine the effects of nutritional element levels in drinking water on body composition of women aged 55-70. Methods: The study population consisted of 80 participants in total, and was divided into three groups as overweight, obese and control women aged between 55-70. The bioelectric impedance device was used for measurements of body composition of the participants. Iron (Fe, copper (Cu, cobalt (Co, zinc (Zn, manganese (Mn and selenium (Se levels of drinking water were measured via plasma mass spectrometry coupled inductively. Results: It was found that Se mineral content in drinking water correlated with the body mass index of the individuals living in Batman, Turkey. Moreover, it was found that Fe, Cu, Co, Zn, Mn and Se levels of drinking water significantly correlated with the abdominal adiposity of women of 55-70. Conclusion: It may be suggested that the obesity risk may be higher in women who are between 55-70 and consume drinking water with high levels of Fe, Cu, Co, Zn, Mn and especially Se.

To confirm the immunogenicity and tolerance of the inactivated, fractionated, and purified influenza vaccine, in a Mexican adult population aged 55 and older, medically served at a Petróleos Mexicanos Hospital (Pemex, Mexican Oil Company). The study was conducted between November and December, 2000, among ninety adult subjects aged 55 years and older who were seen at the Hospital Central Sur Pemex. The primary endpoints regarding immunogenicity were the percentage of individuals with protective antibodies targeting hemagglutinins higher than or equal to 1:40, and the percentage of subjects who seroconverted as measured by a four-fold increase in protective antibody production. Secondary endpoints included the frequency of local and systemic reactions to the vaccine. An additional criterion that was evaluated included antigen-antibody affinity assays to measure the polyclonal antibody response to the vaccine and the specific generation of high-affinity antibodies to viral proteins, before and after vaccination. The antibody protection rate was 95.6% against the HINI strain, 98.9% against the H3N2 strain, and a 100% against the B/Yamanashi strain. Seroconversion to the HINI strain was elicited in 74.4% of subjects, to the H3N2 strain in 88.9%, and to the B/Yamanashi strain in 82.2%. Eighteen (20%) subjects developed local reactions; 17 (18.8%) developed a systemic reaction post vaccination at day 5 and nine subjects (10%) at day 28. Local reactions consisted of pain in 10 (11.1%) subjects, redness in 8 (8.8%), and induration in 6 (6.6%). General malaise, headache, and fever were identified in 10, 8.8, and 0% of subjects, respectively, at day 5, and in 4.4, 6.6, and 0%, respectively, at day 28. Influenza vaccine was highly immunogenic in a healthy Mexican adult population aged 55 years and older. The generation of high-affinity antibodies to the virus after vaccination was also demonstrated. Local and systemic adverse reactions to the vaccine identified in our study

Solar-cycle period-amplitude relation as evidence of hysteresis of the solar-cycle nonlinear magnetic oscillation and the long-term (55 year) cyclic modulation

International Nuclear Information System (INIS)

Yoshimura, H.

1979-01-01

A new dynamical model of the solar cycle has predicted that the cycle should have a hysteretic nature: the behavior of each 11 year cycle should depend on previous cycles. In the light of this new understanding of the dynamical mechanism of the solar cycle, Waldmeier's (hypothetical) law was examined as a yet unexplained characteristic of the cycle by studying the observed sunspot frequency curve. Contrary to this hypothetical law, however, it was found that sunspot cycle curves did not form a single-parameter family characterized by the maximum amplitude of the cycle. The evolutionary trajectories in period-amplitude phase space verified the hysteretic nature of the observed cycle and revealed long-term (55 year instead of the previously claimed 80 year) periodic modulations, called here 55 year grand cycles. Each 55 year grand cycle forms a loop in the phase space, and the characteristics of each 11 year cycle depend on its position in the ascending or descending phase of the grand cycle. This new law was analyzed by the nonlinear multiple-period dynamo oscillation model which has predicted the hysteretic nature. The era from cycle 11 to cycle 15 turned out to be an anomalous one characterized by alternating amplitudes for odd and even cycles. Cycles 16--20 seem to constitute one grand cycle. If this is true, cycle 21 would be the beginning of another grand maximum and the model predicts that its duration would be short

The aim of this study was to determine the clinical characteristics and sonographic features of lymphadenopathy (LAP) and to evaluate the treatment modalities and treatment outcomes in children with tularemia. Demographic characteristics, ultrasonographic and physical examination findings, and treatment outcomes in 55 tularemia patients (24 male and 31 female) with a mean age of 10.8 ± 4.0 years were analyzed retrospectively. Lymph node necrosis was classified in three stages based on ultrasound findings-stage 1, cortical microabscesses; stage 2, cortical and medullar abscesses; stage 3, total necrosis of the lymph node. In total, 50 (90%) of the patients had oropharyngeal, four (8%) had glandular, and one (2%) had oculoglandular tularemia. The most common symptoms were sore throat (67%) and fever (64%). LAP was the most frequently (100%) observed sign. Abscess formation was noted in 36 (65%) patients, of which seven (19%) were sonographically classified as stage 1, 20 (55%) as stage 2, and nine (26%) as stage 3. There was a statistically significant correlation between delayed treatment and stage of abscess formation in lymph nodes (p0.05). In all, nine (16%) of the patients did not respond to medical treatment, and surgical intervention was required. Tularemia should be considered in the differential diagnosis of children presenting with unexplained fever, sore throat, and cervical LAP in endemic areas. Sonographic findings may be useful in the evaluation and staging of this infection.

This analysis deals with the ecologic relationships of dietary fatty acids, food groups and the Mediterranean Adequacy Index (MAI, derived from 15 food groups) with 50-year all-cause mortality rates in 16 cohorts of the Seven Countries Study. A dietary survey was conducted at baseline in cohorts subsamples including chemical analysis of food samples representing average consumptions. Ecologic correlations of dietary variables were computed across cohorts with 50-year all-cause mortality rates, where 97% of men had died. There was a 12-year average age at death population difference between extreme cohorts. In the 1960s the average population intake of saturated (S) and trans (T) fatty acids and hard fats was high in the northern European cohorts while monounsaturated (M), polyunsaturated (P) fatty acids and vegetable oils were high in the Mediterranean areas and total fat was low in Japan. The 50-year all-cause mortality rates correlated (r= -0.51 to -0.64) ecologically inversely with the ratios M/S, (M + P)/(S + T) and vegetable foods and the ratio hard fats/vegetable oils. Adjustment for high socio-economic status strengthened (r= -0.62 to -0.77) these associations including MAI diet score. The protective fatty acids and vegetable oils are indicators of the low risk traditional Mediterranean style diets. KEY MESSAGES We aimed at studying the ecologic relationships of dietary fatty acids, food groups and the Mediterranean Adequacy Index (MAI, derived from 15 food groups) with 50-year all-cause mortality rates in the Seven Countries Study. The 50-year all-cause mortality rates correlated (r = -0.51 to -0.64) ecologically inversely with the ratios M/S [monounsaturated (M) + polyunsaturated (P)]/[saturated (S) + trans (T)] fatty acids and vegetable foods and the ratio hard fats/vegetable oils. After adjustment for high socio-economic status, associations with the ratios strengthened (r = -0.62 to -0.77) including also the MAI diet score

Previous studies on stroke recurrence in younger adults often contain small sample size which makes it difficult to study trends in stroke recurrence over a long period of time. The aim of the present study was to investigate temporal trends in the risk of recurrence in younger patients with a first ischemic stroke. All men and women aged 18-54 years who had survived at least 28 days after a first ischemic stroke from 1987 to 2006 were identified in the Swedish Inpatient Register. The patients were stratified into four 5-year periods according to their admission period and were followed up for a total of four years after the index event with regard to recurrent ischemic stroke. A Cox regression model was used to analyze the risk of recurrent ischemic stroke. Of the 17,149 ischemic stroke patients who were identified, 2432 (14.2%) had a recurrent ischemic stroke event within four years. From the first to the last periods (1987-1991 versus 2002-2006), the four-year risk of recurrent ischemic stroke decreased by 55% (hazard ratio 0.45, 95% confidence interval 0.39-0.53) in men and 59% (hazard ratio 0.41, 95% confidence interval, 0.33-0.50) in women. The cumulative four-year risk was 11.8% (95% CI 10.55-13.25) in men and 9.8% (95% CI 8.40-11.46) in women during the last five-year period (2002-2006). The risk of recurrence among younger ischemic stroke patients has decreased over the past 20 years. Despite these improvements, younger patients are still at a high risk for recurrent ischemic stroke. © 2016 World Stroke Organization.

INTRODUCTION: The current study aims to study people's access to oral and dental health-care services and their satisfaction with the services provided to them. MATERIALS AND METHODS: A descriptive study with multi-stage sampling was conducted on 1360 people aged 16–64 years residing in Isfahan city, Iran. The required data were collected by a questionnaire which comprised of three main parts: demographic characteristics, patients’ access to oral and dental health-care services and its barriers and participants’ satisfaction with access to services. Data were analyzed by SPSS statistical software. RESULTS: The results showed 40% of participants reported an average level for oral health, and 82% of them did not have any problems regarding access to dental care facilities. The main causes of their dissatisfaction were high cost of services (60%) and insufficient health insurance coverage (40%). About 73% reported that they had to spend 30 min or less to access to a dental health-care facility. In addition, 50% of participants were satisfied with the provided services. The main reported reasons for referring to dentists were oral and dental problems (69%) and regular check-ups (15%). There was no significant relationship between participants’ gender, education level, insurance coverage, and access to dental health-care centers (P > 0.05). CONCLUSION: Most participants were satisfied with access to dental healthcare, but they were dissatisfied with the costs and inadequate insurance coverage. About half of the participants were satisfied with the services provided to them, and the highest level of satisfaction was reported for easy access to health-care centers. PMID:29693027

Fibromyalgia (FM) has been understudied in the elderly population, a group with particular vulnerabilities to pain, reduced mobility, and sleep disruption. To characterize FM symptoms and treatments in a cohort of older subjects examined over time to determine the extent to which current, community-based treatment for older FM patients is in accord with published guidelines, and effective in reducing symptoms. A longitudinal, observational study of 51 subjects with FM (range 55-95 years) and 81 control subjects (58-95 years) performed at Banner Sun Health Research Institute in Sun City, AZ, USA. Serial history and examination data were obtained over a 6-year period. FM data included medical history, medications, physical examination, tender point examination, neuropsychological testing, sleep and pain ratings, the Physical Function Subscale of the Fibromyalgia Impact Questionnaire, and other standardized scales to evaluate depression and other psychiatric symptoms, and cognitive and functional impairment. Pain and stiffness that interfered with physical activity, sleep, and mood were reported by 80 % or more of subjects. Over time, pain involved an increasing number of body areas. Over half of subjects were treated with NSAIDs, one-quarter with opioids, and one-quarter with estrogen. Few were treated with dual-acting antidepressants or pregabalin. In this cohort of elders with suboptimally treated FM, substantial persistence of symptoms was seen over time. In general, recommended treatments were either not used or not tolerated. Age-appropriate treatments as well as education of primary care providers are needed to improve treatment of FM in the older population.

The incidence of acute myocardial infarction (AMI) in men exceeds that in women. The extent of this sex disparity varies widely between countries. Variations may also exist between ethnic minority groups and the majority population, but scientific evidence is lacking. A nationwide register-based cohort study was conducted (n = 7,601,785) between 1997 and 2007. Cox Proportional Hazard Models were used to estimate sex disparities in AMI incidence within the Dutch majority population and within ethnic minority groups, stratified by age (30-54, 55-64, ≥65 years). AMI incidence was higher in men than in women in all groups under study. Compared with the majority population (hazard ratio (HR): 2.23; 95% confidence interval (95% CI): 2.21-2.25), sex disparities were similar among minorities originating from the immediate surrounding countries (Belgium, Germany), whereas they were greater in most other minority groups. Most pronounced results were found among minorities from Morocco (HR: 3.48; 95% CI: 2.48-4.88), South Asia (HR: 3.92; 95% CI: 2.45-6.26) and Turkey (HR: 3.98; 95% CI: 3.51-4.51). Sex disparity differences were predominantly evident in those below 55 years of age, and were mainly provoked by a higher AMI incidence in ethnic minority men compared with men belonging to the Dutch majority population. Sex disparities in AMI incidence clearly varied between ethnic minorities and the Dutch majority population. Health prevention strategies may first target at a reduction of AMI incidence in young ethnic minority men, especially those originating from Turkey and South Asia. Furthermore, an increase in AMI incidence in their female counterparts should be prevented. © The European Society of Cardiology 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Full Text Available In the current phase of the IPv6 transition, it is a typical situation that IPv6 only clients should be enabled to communicate with IPv4 only servers. The DNS64+NAT64 tool suite is an excellent solution to this problem. Although several free software DNS64 implementations exist, we point out that there is room for further high performance and computation efficient multithreaded DNS64 implementations. MTD64 was designed to be able to utilize several CPU cores. Whereas MTD64 outperformed BIND more than five times, two critical issues (memory leaking and potential vulnerability to DoS attacks were identified. Therefore MTD64 was redesigned under a new name: mtd64-ng (not capitalized. This paper is about the design, implementation and initial performance estimation of mtd64-ng. The usage of object oriented decomposition and the RAII (Resource Acquisition Is Initialization idiom ensures that raw, sensitive resources (e.g. memory, sockets are always released and it greatly simplifies exception handling. Using the new features of the C++11 standard enabled us to write more efficient and better readable code. The performance of mtd64-ng is compared to that of BIND and MTD64 and it is found that mtd64-ng outperforms even its predecessor, MTD64.

According to the 2013 analysis of the Institute of Health Metrics, high body mass index values are the most important risk factor for disease in Spain. Consequently, we describe the prevalence of total obesity and abdominal obesity in the Spanish adult population (25-64 years) for 2014-2015. The sample was taken from the ENPE study, a cross-sectional study with a representative sample of the noninstitutionalized population (n = 6800) carried out between May 2014 and May 2015. This analysis refers to the population between age 25 and 64 years (n = 3966). The anthropometric measurements were performed by trained observers at participants' homes according to standard international protocols. Body mass index ≥ 25 was defined as overweight and ≥ 30 as obesity. Abdominal obesity was classified as waist > 102 cm in men and > 88 cm in women. The estimated prevalence of overweight in the Spanish adult population (25-64 years) was 39.3% 95% confidence interval [95%CI], 35.7%-42.9%). The prevalence of general obesity was 21.6% (95%CI, 19.0%-24.2%) and, more specifically, was 22.8% (95%CI, 20.6%-25.0%) among men and 20.5% (95%CI, 18.5%-22.5%) among women, and rose with age. The prevalence of abdominal obesity was estimated at 33.4% (95%CI, 31.1%-35.7%) and was higher among women (43.3%; 95%CI, 41.1%-45.8%) than among men (23.3%; 95%CI, 20.9%-25.5%), and also rose with age. The prevalence of general obesity and abdominal obesity in Spain is high, although the distribution differs according to autonomous community. A comparison with earlier data reveals a considerable increase in overweight, indicating the need for routine monitoring and comprehensive initiatives.

Lost PLYs, lost income, extra welfare payments, lost taxation revenue, lost GDP. 18 100 people are out of the labour force due to diabetes in 2015, increasing to 21 400 in 2030 (18% increase). National costs consisted of a loss of $A467 million in annual income in 2015, increasing to $A807 million in 2030 (73% increase). For the government, extra annual welfare payments increased from $A311 million in 2015 to $A350 million in 2030 (13% increase); and lost annual taxation revenue increased from $A102 million in 2015 to $A166 million in 2030 (63% increase). A loss of $A2.1 billion in GDP was projected for 2015, increasing to $A2.9 billion in 2030 attributable to diabetes through its impact on PLYs. Individuals incur significant costs of diabetes through lost PLYs and lost income in addition to disease burden through human suffering and healthcare costs. The government incurs extra welfare payments, lost taxation revenue and lost GDP, along with direct healthcare costs. Published by the BMJ

Most government employees have access to retiree health coverage, which provides them with group health coverage even if they retire before Medicare eligibility. We study the impact of retiree health coverage on the labor supply of public sector workers between the ages of 55 and 64. We find that retiree health coverage raises the probability of stopping full time work by 4.3 percentage points (around 38 percent) over two years among public sector workers aged 55-59, and by 6.7 percentage points (around 26 percent) over two years among public sector workers aged 60-64. In the younger age group, retiree health insurance mostly seems to facilitate transitions to part-time work rather than full retirement. However, in the older age group, it increases the probability of stopping work entirely by 4.3 percentage points (around 22 percent). Copyright © 2014 Elsevier B.V. All rights reserved.

The UERRA project is a 4-year project (2014-2017) financed by the European Union under its 7th Framework Programme SPACE. One of its main objectives is to provide a 50-year reanalysis dataset of surface essential climate variables (ECV) at 5.5km grid at European scale, together with, as much as possible, uncertainty estimates. One of the ECV is the precipitation and this variable is of essential interest in weather forecasting, climate study and to "drive" hydrological model for water management, or agrometeorology. After a brief description of the method used for the precipitation analysis (Soci et al. 2016)during this project, the preliminary results will be presented. The estimation of uncertainties will be also discussed associated with the problem of the evolution of the observation density network and its impact on the long term series. Additional information about the UERRA project can be found at http://www.uerra.eu The research leading to these results has received funding from the European Union, Seventh Framework Programme (FP7-SPACE-2013-1) under grant agreement no 607193.

During the last 10 years, the Geograns Program within the NAUGRAN initiative of the University of Valencia is using trekking as a way to teach in the field Earth Science. This paper review the contribution of this program and show the results and future challenges. The life expectancy is growing all over the world. This is a clear trend in the Western societies where after two generations there is a large group of inhabitants that have a new life after retirement. The universities must understand that this new group of citizens need services that will allow them to know better the society. This is why the University of Valencia developed in the end of the 90's a program to teach to students older than 55. The program that allows to those students to attend lectures at the University is called NAUGRAN. This is a program for more than one thousand students that cover the needs of a group that is having more and more population over the age of 55, and with a life expectancy that surpass the 81 years in Spain. Teaching History, Arts, Sciences or Literature can be easily due for those 55-old students. However, teaching geosciences is being very difficult, as the students must visit the field and the laboratory. Within the GEOGRANS project, and during the last six years, Physical Geography was taught to students older than 55 in independent lecture rooms and field and laboratory classes. The main strategy was to show them the concepts and the ideas of the Physical Geography in the field. The excursions allow to shown the main features of the landscape (rivers, mountains, rocks…) and the impacts of the humankind on the changes of the nature to the students. The program is now 6 years old and it is being very successful with more than 200 hundreds participants and with excursion every two weeks. This paper will show the importance of teaching to students that arrive to the university after retirement. And that trekking is a successful strategy as the students realise

Full Text Available Abstract Background Members of the Baculoviridae encode two types of proteins that mediate virus:cell membrane fusion and penetration into the host cell. Alignments of primary amino acid sequences indicate that baculovirus fusion proteins of group I nucleopolyhedroviruses (NPV form the GP64 superfamily. The structure of these viral penetrenes has not been determined. The GP64 superfamily includes the glycoprotein (GP encoded by members of the Thogotovirus genus of the Orthomyxoviridae. The entry proteins of other baculoviruses, group II NPV and granuloviruses, are class I penetrenes. Results Class III penetrenes encoded by members of the Rhabdoviridae and Herpesviridae have an internal fusion domain comprised of beta sheets, other beta sheet domains, an extended alpha helical domain, a membrane proximal stem domain and a carboxyl terminal anchor. Similar sequences and structural/functional motifs that characterize class III penetrenes are located collinearly in GP64 of group I baculoviruses and related glycoproteins encoded by thogotoviruses. Structural models based on a prototypic class III penetrene, vesicular stomatitis virus glycoprotein (VSV G, were established for Thogoto virus (THOV GP and Autographa california multiple NPV (AcMNPV GP64 demonstrating feasible cysteine linkages. Glycosylation sites in THOV GP and AcMNPV GP64 appear in similar model locations to the two glycosylation sites of VSV G. Conclusion These results suggest that proteins in the GP64 superfamily are class III penetrenes.

Schmidt, Caroline; Bergström, Göran

2017-07-01

Cardiovascular (CV) disease (CVD) is a leading cause of morbidity and mortality worldwide. Most CV events are caused by atherosclerosis. Diabetes and impaired glucose tolerance are associated with greater carotid intima-media thickness (IMT) and increased risk for CVD. The present study examined if common carotid artery IMT (CCAIMT) is predictive of CVD irrespective of glucose tolerance category and glycated hemoglobin (HbA1c) in a sample of 639 women with different glucose tolerance categories. During 7-year follow-up, 30 events in the cardiac and 32 events in the cerebral territory were documented. Unadjusted Cox hazard models showed that CCAIMT, glucose tolerance category, and HbA1c were associated with increased risk. An adjusted and extended model, including CCAIMT, glucose tolerance category, and HbA1c, showed that CCAIMT was still associated with events with an almost unchanged hazard ratio. In conclusion, this study suggests that CCAIMT is predictive of major CV events during 7-year follow-up, irrespective of glucose tolerance category, HbA1c, and other established risk factors in a cohort of 64-year-old women.

The life expectancy growth is a general trend for the world population, which translates into an increase of people older than 55 years in Western societies. This entails to the rise of health problems as well as large investments in healthcare. In general, we are spectators Y tambe voldria saber si ens pots fer una asse of how a large group of citizens have a new life after retirement. The XXI century societies are facing the problem of the need of a healthy population, even after retirement. There is a need in developing new strategies to allow those citizens to improve their knowledge of the environmental changes. The research in Soil Science and related disciplines is the strategy we are using on the Geograns program to inform the students (older than 55) about the changes the Earth and the Soil System are suffering. And this should be done in a healthy and active teaching environment. The NAUGRAN program is being developed by the University of Valencia for more than 10 years and shows the advances on education for senior students. Within this program, Geograns is bringing the environmentalist ideas to the students. This is a difficult task as those students were born in a society were nature was created to be exploited and not to be conserved (e.g. Green Revolution, agricultural transformations of the 60's in Spain). This is the reason why the University of Valencia developed at the end of the 90's a program to teach students older than 55. This paper shows the advances on new strategies developed during 2013 with a group of these senior students. The main strategy was to take the students to visit the nature and to explain the functioning of the Earth and Soil System. Those visits were organized with the collaboration of scientist, environmentalist, farmers and technicians; and the guiding thread was trekking. This mix showed our students different views and sides of the same phenomena (e.g. tillage operations, soil erosion problems, water quantity and

Fish otoliths are calcium carbonate biominerals that are involved in hearing and balance sensing. An organic matrix plays a crucial role in their formation. Otolith matrix macromolecule-64 (OMM-64) is a highly acidic, calcium-binding protein (CBP) found in rainbow trout otoliths. It is a component of high-molecular-weight aggregates, which influence the size, shape and polymorph of calcium carbonate in vitro. In this study, a protocol for the efficient expression and purification of OMM-64 was developed. For the first time, the complete structural characteristics of OMM-64 were described. Various biophysical methods were combined to show that OMM-64 occurs as an intrinsically disordered monomer. Under denaturing conditions (pH, temperature) OMM-64 exhibits folding propensity. It was determined that OMM-64 binds approximately 61 calcium ions with millimolar affinity. The folding-unfolding experiments showed that calcium ions induced the collapse of OMM-64. The effect of other counter ions present in trout endolymph on OMM-64 conformational changes was studied. The significance of disordered properties of OMM-64 and the possible function of this protein is discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

Early pubertal timing is known to put women at greater risk for adverse physiological and psychological health outcomes. Of the factors that influence girls' pubertal timing, stress experienced during childhood has been found to advance age at menarche (AAM). However, it is not known if stress experienced by mothers during or in the months before conception can be similarly associated with earlier pubertal timing. Prenatal maternal stress (PNMS) is associated with metabolic changes, such as increased childhood adiposity and risk of obesity, that have been associated with earlier menarchal age. Using a prospective longitudinal design, the present study tested whether PNMS induced by a natural disaster is either directly associated with earlier AAM, or whether there is an indirect association mediated through increased girls' body mass index (BMI) during childhood. A total of 31 girls, whose mothers were exposed to the Quebec's January 1998 ice storm during pregnancy were followed from 6 months to 5 1/2 to 5.5 years of age. Mother's stress was measured within 6 months of the storm. BMI was measured at 5.5 years, and AAM was assessed through teen's self-report at 13.5 and 15.5 years of age. Results revealed that greater BMI at 5.5 years mediated the effect of PNMS on decreasing AAM [B=-0.059, 95% confidence intervals (-0.18, -0.0035)]. The present study is the first to demonstrate that maternal experience of stressful conditions during pregnancy reduces AAM in the offspring through its effects on childhood BMI. Future research should consider the impact of AAM on other measures of reproductive ability.

Citation analysis helps to identify the research trends within a research field and helps to identify the most frequently occurring parameters. The aim of this study was to identify the 100 most-cited articles in the field of dental, oral, and maxillofacial traumatology over the past 64 years. A comprehensive list of the most-cited articles in dental, oral, and maxillofacial trauma was compiled using 'All Databases' section of the ISI Web of Knowledge. Related articles were considered to be those articles in which part or all of the experiment or study was related to dental and/or oral and maxillofacial trauma. In case reports, if a part of a treatment plan was related to the topic, that article was considered to be relevant. The characteristics analyzed included number of citations, authors, journals, institution, country of origin, publication year, article type, study material, and topic. The number of citations for each article ranged from 69 to 229. The journal Dental Traumatology was the most represented, followed by the journal Oral and Maxillofacial Surgery. Of the 100 articles, 83% were original articles, 15% were review articles, and 2% were case report/case series. Therapy and prognosis-related topics were the most common topics. Most articles came from institutions in the United States, followed by the Scandinavian countries. University Hospital of Copenhagen was the source of the highest number (34) of the most-cited articles; the same author wrote or co-wrote 22 of the 100 most-cited articles. The list of most-cited articles in the field of dental, oral, and maxillofacial traumatology gives a good scientometric picture of trauma research in the world. A large number of the most-cited articles are mainly from the field of dental traumatology and originate from a few research teams. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Prediction of cancer incidence in Tyrol/Austria for year of diagnosis 2020.

Oberaigner, Willi; Geiger-Gritsch, Sabine

2014-10-01

Prediction of the number of incident cancer cases is very relevant for health planning purposes and allocation of resources. The shift towards elder age groups in central European populations in the next decades is likely to contribute to an increase in cancer incidence for many cancer sites. In Tyrol, cancer incidence data have been registered on a high level of completeness for more than 20 years. We therefore aimed to compute well-founded predictions of cancer incidence for Tyrol for the year 2020 for all frequent cancer sites and for all cancer sites combined. After defining a prediction base range for every cancer site, we extrapolated the age-specific time trends in the prediction base range following a linear model for increasing and a log-linear model for decreasing time trends. The extrapolated time trends were evaluated for the year 2020 applying population figures supplied by Statistics Austria. Compared with the number of annual incident cases for the year 2009 for all cancer sites combined except non-melanoma skin cancer, we predicted an increase of 235 (15 %) and 362 (21 %) for females and males, respectively. For both sexes, more than 90 % of the increase is attributable to the shift toward older age groups in the next decade. The biggest increase in absolute numbers is seen for females in breast cancer (92, 21 %), lung cancer (64, 52 %), colorectal cancer (40, 24 %), melanoma (38, 30 %) and the haematopoietic system (37, 35 %) and for males in prostate cancer (105, 25 %), colorectal cancer (91, 45 %), the haematopoietic system (71, 55 %), bladder cancer (69, 100 %) and melanoma (64, 52 %). The increase in the number of incident cancer cases of 15 % in females and 21 % in males in the next decade is very relevant for planning purposes. However, external factors cause uncertainty in the prediction of some cancer sites (mainly prostate cancer and colorectal cancer) and the prediction intervals are still broad. Therefore

This paper compares the results of mammographic screening in women aged 65 years and older to those of women aged 50--64 years, to define risk factors and prior use of mammography in these women, and to determine whether mammographic abnormalities are managed differently in the two age groups. Historical data, mammographic findings, and biopsy results were analyzed for all women over 50 years of age screened during 1988 (2,862 patients) at a university hospital-based outpatient center and mobile van, excluding those referred by oncologists. The following factors were determined for patients screened at the outpatient center and the mobile van, with both groups divided according to patient age (50--64 vs ≥ 65 years): presence of risk factors, previous biopsy, exogenous hormones, percentage of black patients, previous mammography, biopsy rate, cancer detection rate, positive nodes, and presence of tumors smaller than 1 cm or ductal carcinoma in-situ

Full Text Available Care in dialysis is often associated with significant morbidity and mortality during the first year. Knowledge of its magnitude and causes could improve the prognosis of these patients. The aim of this study was to evaluate the survival and morbidity during the first year of dialysis for patients who initiated their dialysis between January 1, 2009 and December 31, 2009 and to study their possible correlation with baseline status at the beginning of treatment. A multi-center retrospective study was conducted in 11 dialysis centers. Clinical data at the beginning of dialysis and during the following year were collected. Mortality and morbidity risk factors were assessed by comparing different groups. Statistical analysis was performed with SPSS version 11. This study involved 134 patients, 79 men and 55 women, of whom 132 were on hemodialysis and two patients were on peritoneal dialysis. The mean age at initiation of treatment was 54.37 ± 18.09 years. Initial causes of nephropathy were dominated by diabetes (44.02% and hypertension (11.19%. Among these patients, 39.55% had never received prior nephrological follow-up and 64.92% had started renal replacement therapy on an emergency basis. The initial clinical state was dominated by the presence of hypertension (50.74%, diabetes (44.02%, coronary insufficiency (13.43% and heart failure (7.46%. Only 26.86% of the incident patients showed no comorbidity. During the first year of follow-up, 37.31% of the patients experienced at least one episode of comorbidity. Hospitalization was necessary in about half of these cases (17.91% of all patients. The overall mortality rate was 14.17%. One patient received a kidney transplant. The mortality rate in the first year of dialysis was lower in our study than in other series. Regular nephrological follow-up of these patients before they reach end-stage could have a significant influence on survival in dialysis.

Full Text Available Newborn chicks are susceptible to Salmonella enterica serovar Enteritidis (SE. The objective of this study was to evaluate the effect of Lactobacillus probiotic isolated from chicken feces on heterophil phagocytosis in broiler chicks. A total of 150 newborn broiler chicks were divided into 5 groups (30 chicks per group as follows: group 1 (normal control, given feed and water only, group 2 (positive control given feed, water and SE infection, group 3 (L61 treated given feed, water, SE infection followed by Lactobacillus salivarius L61 treatment, group 4 (L55 treated given feed, water, SE infection followed by L. salivarius L55 treatment, and group 5 given feed, water, SE infection followed by L. salivarius L61 + L55 combination treatment. After SE infection, L. salivarius treatment lasted for 7 days. The results showed that L. salivarius L61 and L. salivarius L55 treatment, either alone or combination of both, increased the survival rate after SE infection, and upregulated heterophil phagocytosis and phagocytic index (PI. Conversely, chick groups treated with Lactobacillus showed lower SE recovery rate from cecal tonsils than that of the positive control group. The PI values of the chicken group with SE infection, followed by the combination of L. salivarius L61 and L. salivarius L55 were the highest as compared to either positive control or normal control group. Two Lactobacillus strains supplementation group showed significantly (p<0.05 higher PI value at 48 h than 24 h after treatment.

Complement-mediated erythrocyte destruction can cause both intravascular and extravascular haemolysis. Complement regulatory proteins protect cells from such effects of the complement system. We aimed to perform quantitative analysis of membrane-bound complement regulators, CD55 (decay accelerating factor – DAF), CD35 (complement receptor type 1 – CR1), and CD59 (membrane attack complex inhibitory factor – MACIF) on peripheral red blood cells by flow cytometry. Material and methods The present study was carried out on 47 β-thalassemia major (β-TM) patients, 20 β-thalassaemia intermedia (β-TI) patients, and 17 healthy volunteers as control subjects. Results CD55 levels of β-TM patients (58.64 ±17.06%) were significantly decreased compared to β-TI patients (83.34 ±13.82%) and healthy controls (88.57 ±11.69%) (p < 0.01). CD59 levels of β-TM patients were not significantly different than β-TI patients and controls, but CD35 levels were significantly lower in the β-TM patients (3.56 ±4.87%) and β-TI patients (12.48 ±9.19%) than in the control group (39.98 ±15.01%) (p < 0.01). Conclusions Low levels of CD55 and CD35 in thalassaemia major patients indicates a role for them in the aetiopathogenesis of haemolysis in this disease, and also this defect in a complement system may be responsible for the chronic complications seen in these patients.

Performance Analysis of MTD64, our Tiny Multi-Threaded DNS64 Server Implementation: Proof of Concept

Directory of Open Access Journals (Sweden)

Gábor Lencse

2016-07-01

In this paper, the performance of MTD64 is measured and compared to that of the industry standard BIND in order to check the correctness of the design concepts of MTD64, especially of the one that we use a new thread for each request. For the performance measurements, our earlier proposed dns64perf program is enhanced as dns64perf2, which one is also documented in this paper. We found that MTD64 seriously outperformed BIND and hence our design principles may be useful for the design of a high performance production class DNS64 server. As an additional test, we have also examined the effect of dynamic CPU frequency scaling to the performance of the implementations.

Type 2 diabetes mellitus (T2DM) is the most common form of diabetes. Risk factors for its development include older age, obesity, family history of diabetes, history of gestational diabetes, impaired glucose metabolism, physical inactivity, and race/ethnicity. The purpose of this study was to characterize T2DM burden, from a patient perspective, with respect to age and race/ethnicity. Adults aged ≥18 years with T2DM from a large, Internet-based, nationwide survey were retrospectively analyzed. Demographic and clinical characteristics (glycemic control, body mass index [BMI], comorbidities, and diabetes-related complications), hypoglycemic episodes, and medication adherence were used to assess diabetes burden. Degree of burden was compared across age (18-64, 65-74, and ≥75 years) and racial/ethnic (white, African American, Hispanic, Asian, and American Indian) groups. An apparent association was found between glycemic control and medication adherence. Hispanics had the lowest percentage of participants with a hemoglobin A1c (HbA1c) level groups. Conversely, American Indians and whites had the best glycemic control, HbA1c knowledge, and medication adherence. The 18- to 64-year age group had the poorest glycemic control (28.8%), the most with unknown HbA1c levels (46.3%), and the poorest medication adherence of the age groups. Mean BMIs were high (>30 mg/kg(2)) for all racial/ethnic groups other than the Asian group (28.9 mg/kg(2)). Approximately 71% of Asians were obese or overweight compared with ≥90% in the other racial/ethnic groups. Mean BMIs decreased with increasing age group (34.5, 32.6, and 29.8 kg/m(2) for the age groups of 18-64, 65-74, and ≥75 years, respectively). Regarding diabetes-related comorbidities, the Asian group had the lowest percentages of those with hypertension (39.1%) and hypercholesterolemia (46.6%). The Asian group had the lowest mean Charlson Comorbidity Index (CCI) score (score of 1.4); the American Indian group had the highest

Jumping mechanography uses maximal countermovement jumps to test obtain such as jump power (JPow). Recently, it has been shown to be a safe method for assessing muscle function in older adults; however, little is known about the relationships between JPow, muscle strength, and sarcopenia status. The purpose of this study was to examine jump performance, muscle strength, and sarcopenia status in older adults. This was a cross-sectional study that included men (n = 27) and women (n = 33) (55-75 years) recruited from the general community. Participants completed health status and physical activity questionnaires. Body composition, including appendicular skeletal muscle mass (ASM), bone free lean body mass, and relative skeletal muscle mass index, were assessed by total body dual-energy x-ray absorptiometry scans. The criteria for sarcopenia were relative skeletal muscle mass index values less than 7.26 kg/m2 for men and less than 5.45 kg/m2 for women. Three vertical jumps on a jump mat were performed to assess JPow, jump velocity (JVel), and jump height (JHt). Muscle strength was measured by 1RM testing for leg press (LP) and right and left hip abduction isotonic resistance exercises. Sarcopenia was found in 20% (12/60) of the participants. Jump power was significantly lower (P = .001) in the sarcopenia group than in the normal group, 651.1 (41.7) W versus 851.0 (27.4) W, respectively. Jump power and JHt were significantly (P mass. Significant (P muscle strength (LP, right and left hip abduction). The jump test protocol was conducted safely with no injuries or balance issues. Our finding of lower JPow in sarcopenic individuals adds new information to the existing literature on age-related declines in muscle power. Community-dwelling individuals classified as sarcopenic had significantly lower JPow but not muscle strength compared with their counterparts with normal amounts of muscle mass. Jump test variables were positively correlated with lean tissue and lower body

The aim of our study was to evaluate the value of coronal image reconstructions of HRCT with using 64 MDCT scans for the assessment of bronchiectasis. Chest CT scans (0.6-mm collimation, table speed of 14 mm/sec and a rotation time of 0.5 sec) that employed 64 MDCT images (Somatom Sensation 64, Siemens) without contrast media were performed in 56 patients (21 males and 35 females, mean age: 55 years) who displayed hemoptysis. The images were reconstructed with a 1 mm slice thickness in the axial (10 mm apart) and coronal (10 mm apart) planes with using a high frequency algorithm, and they were sent to PACS monitors. The axial images were assessed with and without the coronal images by two radiologists at two separate occasions. The presence of bronchiectasis was decided upon by consensus diagnosis of the two radiologists. The detection rates of bronchiectasis were compared between the readings with using the axial images alone and the readings with using both the axial and coronal images. The detection rate of bronchiectasis was significantly higher with using both the axial and coronal images than with using with axial images alone (82.1%, 46/56 patients Vs 64.3%, 36/56 patients, respectively, ρ = 0.001). The detection rates for all the lobes, except for the superior division of the left upper lobe, were significantly improved with using both the axial and coronal images (RUL; ρ = 0.013, RML; ρ = 0.002, RLL; 0.024, Lt lingular segment; ρ = 0.004, LLL; ρ = 0.018). The coronal images of HRCT with using 64 MDCT improved the detection rate of bronchiectasis in the patients with hemoptysis when they were used in conjunction with the standard axial images. We suggest that HRCT with the coronal images should be obtained for the patients with hemoptysis, despite that the simple chest radiographs are often normal or they have non-specific findings

Shoreline change has been an increasing concern for low-lying and vulnerable coastal zones worldwide, especially in estuarine delta regions, which generally have significant economic development, large human settlements and infrastructures. Thus, long time-series shoreline change data are useful for understanding how shorelines respond to natural and anthropogenic activities, as well as for providing greater insights into coastal protection and sustainable development in the future. For the first time, this study analyzes 55 years of spatiotemporal shoreline changes in Shanghai, China, by integrating the historical Declassified Intelligence Satellite Photography (DISP) and Landsat time series data at five-year intervals from 1960 to 2015. Twelve shorelines were interpreted from DISP and Landsat images. The spatiotemporal changes in the shorelines were explored at five-year intervals within the study period for the Shanghai mainland and islands. The results indicate that shorelines in Shanghai accreted significantly over the last 55 years, but different accretion patterns were observed in Chongming Dongtan. The rate of shoreline change varied in different areas, and the most noticeable expansions were Chongming Beitan, Chongming Dongtan, Hengsha Dongtan, and Nanhuizui. The length of the entire shoreline increased by 25.7% from 472.6 km in 1960 to 594.2 km in 2015. Due to the shoreline changes, the Shanghai area expanded by 1,192.5 km2 by 2015, which was an increase of 19.9% relative to its 1960 area. The Digital Shoreline Analysis System (DSAS) was used to compute rate-of-change statistics. Between 1960 and 2015, 10.6% of the total transects exceeded 3 km of Net Shoreline Movement (NSM), with a maximum value of approximately 20 km at eastern Hengsha Island. The average Weighted Linear Regression Rate (WLR) of the Shanghai shoreline was 52.2 m/yr from 1960 to 2015; there was 94.1% accretion, 3.1% erosion, and 2.8% with no significant change. In addition, the driving

A recent Korea National Health and Nutrition Survey indicated inadequate riboflavin intake in Koreans, but there is limited research regarding riboflavin status in South Korea. The purpose of this study was to determine riboflavin intake and status of Korean adults. Three consecutive 24-h food recalls were collected from 412 (145 men and 267 women) healthy adults, aged 20-64 years, living in South Korea and urine samples were collected from 149 subjects of all subjects. The dietary and total (dietary plus supplemental) riboflavin intake was 1.33 ± 0.34 and 2.87 ± 6.29 mg/day, respectively. Approximately 28% of the subjects consumed total riboflavin less than the Estimated Average Requirement. Urinary riboflavin excretion was 205.1 ± 190.1 μg/g creatinine. Total riboflavin intake was significantly positively correlated to the urinary riboflavin excretion. (r = 0.17171, p = 0.0363). About 11% of the Korean adults had urinary riboflavin riboflavin deficiency and 21% had low status of riboflavin (27 μg/g creatinine ≤ urinary riboflavin riboflavin status. In some adults in Korea, consumption of riboflavin-rich food sources should be encouraged.

To analyze the association between the Trp64Arg polymorphism of the ADRB3 gene, maximal fat oxidation rates and the lipid profile levels in non-obese adolescents. 72 schoolchildren, of both genders, aged between 11 and 17 years, participated in the study. The anthropometric and body composition variables, in addition to total cholesterol, HDL-c, LDL-c, triglycerides, insulin, and basal glycemia, were evaluated. The sample was divided into two groups according to the presence or absence of the polymorphism: non-carriers of the Arg64 allele, i.e., homozygous (Trp64Trp: n=54), and carriers of the Arg64 allele (Trp64Arg+Arg64Arg: n=18), in which the frequency of the Arg64 allele was 15.2%. The maximal oxygen uptake and peak of oxygen uptake during exercise were obtained through the symptom-limited, submaximal treadmill test. Maximal fat oxidation was determined according to the ventilatory ratio proposed in Lusk's table. Adolescents carrying the less frequent allele (Trp64Arg and Arg64Arg) had higher LDL-c levels (p=0.031) and lower maximal fat oxidation rates (p=0.038) when compared with non-carriers (Trp64Trp). Although the physiological processes related to lipolysis and lipid metabolism are complex, the presence of the Arg 64 allele was associated with lower rates of FATMAX during aerobic exercise, as well as with higher levels of LDL-c in adolescents.

A randomized, controlled fall-prevention study including 199 patients operated on for femoral neck fracture reduced inpatient falls and injuries. No statistically significant effects of the intervention program could be detected after discharge. It seems that fall-prevention must be part of everyday life in fall-prone old people. This study evaluates whether a postoperative multidisciplinary, multifactorial fall-prevention program performed by a geriatric team that reduced inpatient falls and injuries had any continuing effect after discharge. The intervention consisted of staff education, systematic assessment and treatment of fall risk factors and vitamin D and calcium supplementation. The randomized, controlled trial with a one-year follow-up at Umeå University Hospital, Sweden, included 199 patients operated on for femoral neck fracture, aged > or = 70 years. After one year 44 participants had fallen 138 times in the intervention group compared with 55 participants and 191 falls in the control group. The crude postoperative fall incidence was 4.16/1,000 days in the intervention group vs. 6.43/1,000 days in the control group. The incidence rate ratio was 0.64 (95% CI: 0.40-1.02, p = 0.063). Seven new fractures occurred in the intervention group and 11 in the control group. A team applying comprehensive geriatric assessment and rehabilitation, including prevention and treatment of fall-risk factors, reduced inpatient falls and injuries, but no statistically significant effects of the program could be detected after discharge. It seems that fall-prevention must be part of everyday life in fall-prone elderly.

Evaluation of di-amino phenol substituted EDTA for use in radiolabelling proteins with 64Cu

Schmidt, P.F.; Smith, S.V.; DiBartolo, N.M.

1996-01-01

This study involves a high yielding synthesis of a novel di-amino-phenol substituted EDTA (DAHA-EDTA) ligand and its radiolabelling chemistry with 64 Cu produced at the National Medical Cyclotron (NMC). High activity levels (up to 59.2 GBq EOB) of 64 Cu is co-produced during the production of 67 Ga from enriched 68 Zn. Waste eluent from the NMC 67 Ga production was evaporated to dryness and found to contain by products such as 57 Ni, 57 Co, 64 Cu, 67 Cu and 55 Co. A new method involving low acid concentration aqueous/organic mixtures with an anion exchange (AG 1-X8, BioRad) have been used to isolate the carrier-free 64 Cu. The specific activity of the 64 Cu (5 x 10 14 Bq/g) was found to be higher than that produce by Australian radioisotopes (ARI). The synthesis of the ligand involves the refluxing of EDTA anhydride in the presence of 4-nitro-2-amino-phenol in acetonitrile to produce the di-nitro derivative (DNHA- EDTA) in > 95% yield. The DNHA-EDTA is then reduced in the presence of activated palladium charcoal with sodium borohydride under an inert atmosphere at room temperature. The reaction mixture was acidified and the catalyst removed to obtain the final product, DAHA-EDTA. Labelling of proteins (B72.3, DD-3B6/22 and streptavidin) has been achieved with the DAHA-EDTA ligand. The reaction mixture is left to incubate for 1 h at 37 deg C and radiolabelled protein is then isolated using size exclusion chromatography

Ten-year trends in coronary calcification in individuals without clinical cardiovascular disease in the multi-ethnic study of atherosclerosis.

Full Text Available Coronary heart disease (CHD incidence has declined significantly in the US, as have levels of major coronary risk factors, including LDL-cholesterol, hypertension and smoking, but whether trends in subclinical atherosclerosis mirror these trends is not known.To describe recent secular trends in subclinical atherosclerosis as measured by serial evaluations of coronary artery calcification (CAC prevalence in a population over 10 years, we measured CAC using computed tomography (CT and CHD risk factors in five serial cross-sectional samples of men and women from four race/ethnic groups, aged 55-84 and without clinical cardiovascular disease, who were members of Multi-Ethnic Study of Atherosclerosis (MESA cohort from 2000 to 2012. Sample sizes ranged from 1062 to 4837. After adjusting for age, gender, and CT scanner, the prevalence of CAC increased across exams among African Americans, whose prevalence of CAC was 52.4% in 2000-02, 50.4% in 2003-04, 60.0% is 2005-06, 57.4% in 2007-08, and 61.3% in 2010-12 (p for trend <0.001. The trend was strongest among African Americans aged 55-64 [prevalence ratio for 2010-12 vs. 2000-02, 1.59 (95% confidence interval 1.06, 2.39; p = 0.005 for trend across exams]. There were no consistent trends in any other ethnic group. Risk factors generally improved in the cohort, and adjustment for risk factors did not change trends in CAC prevalence.There was a significant secular trend towards increased prevalence of CAC over 10 years among African Americans and no change in three other ethnic groups. Trends did not reflect concurrent general improvement in risk factors. The trend towards a higher prevalence of CAC in African Americans suggests that CHD risk in this population is not improving relative to other groups.

Pneumonia is associated with considerable mortality. However, the information on age-specific prognostic factors for death from pneumonia is limited. Patients hospitalised with a diagnosis of pneumonia through the emergency department were stratified into three age groups: 18-64 years; 65-84 years; and ≥ 85 years. Multivariate logistic regression and receiver operating characteristic (ROC) curve analyses were conducted to evaluate prognostic factors for mortality and the performance of pneumonia severity scoring tools for mortality prediction. There were 1,902 patients (18-64 years: 614 [32.3%]; 65-84 years: 944 [49.6%]; ≥ 85 years: 344 [18.1%]) enrolled. Mortality rates increased with age (18-64 years: 7.3%; 65-84 years: 16.1%; ≥ 85 years: 29.7%; p aged 18-64 years. Male gender, malignancy, congestive heart failure and eight other parameters reflecting acute disease severity were associated with mortality among patients aged 65-84 years. For patients aged ≥ 85 years, altered mental status, tachycardia, blood urea nitrogen, hypoxaemia, arterial pH and pleural effusion were significantly predictive of mortality. Pneumonia Severity Index (PSI) was more sensitive than CURB-65 (Confusion, Uraemia, Respiratory rate ≥ 30 per minute, low Blood pressure, age 65 years or older) for mortality prediction across all age groups. The predictive effect of prognostic factors for mortality varied among patients with pneumonia from the different age groups. PSI performed significantly better than CURB-65 for mortality prediction, but its discriminative power decreased with advancing age.

Among perinatally infected children, the effects of certain alleles of the CCR5 and CCR2 genes on the rate of disease progression remain unclear. We addressed the effects of CCR5-delta32 and CCR2-64I in an international meta-analysis. Genotype data were contributed from 10 studies with 1317 HIV-1-infected children (7263 person-years of follow-up). Time-to-event analyses were performed stratified by study and racial group. Endpoints included progression to clinical AIDS, death, and death after the diagnosis of clinical AIDS. The time-dependence of the genetic effects was specifically investigated. There was large heterogeneity in the observed rates of disease progression between different cohorts. For progression to clinical AIDS, both CCR5-delta32 and CCR2-64I showed overall non-significant trends for protection [hazard ratios 0.84, 95% confidence interval (CI) 0.58-1.23; and 0.87, 95% CI 0.67-1.14, respectively]. However, analyses of survival showed statistically significant time-dependence. No deaths occurred among CCR5-delta32 carriers in the first 3 years of life, whereas there was no protective effect (hazard ratio 0.95; 95% CI 0.43-2.10) in later years (P=0.01 for the time-dependent model). For CCR2-64I, the hazard ratio for death was 0.69 (95% CI 0.39-1.21) in the first 6 years of life and 2.56 (95% CI 1.26-5.20) in subsequent years (P<0.01 for the time-dependent model). CCR5-delta32 and CCR2-64I offered no clear protection after clinical AIDS had developed. The CCR5-delta32 and CCR2-64I alleles are associated with a decreased risk of death among perinatally infected children, but only for the first years of life.

A population-based controlled study to determine whether adult (55-74 years) neurological disease deaths are continuing to rise and are there significant differences between America and the twenty developed countries 1989-91 and 2012-14. Total Neurological Deaths (TND) rates contrasted against control Cancer and Circulatory Disease Deaths (CDD) extrapolated from WHO data. Confidence intervals compare USA and the other countries over the period. The Over-75's TND and population increases are examined as a context for the 55-74 outcomes. Male neurological deaths rose >10% in eleven countries, the other countries average rose 20% the USA 43% over the period. Female neurological deaths rose >10% in ten counties, averaging 14%, the USA up 68%. USA male and female neurological deaths increased significantly more than twelve and seventeen countries, respectively. USA over-75s population increased by 49%, other countries 56%. Other countries TND up 187% the USA rose fourfold. Male and female cancer and CDD fell in every country averaging 26% and 21%, respectively, and 64% and 67% for CDD. Male neurological rates rose significantly more than Cancer and CCD in every country; Female neurological deaths rose significantly more than cancer in 17 countries and every country for CDD. There was no significant correlation between increases in neurological deaths and decreases in control mortalities. There are substantial increases in neurological deaths in most countries, significantly so in America. Rises in the 55-74 and over-75's rates are not primarily due to demographic changes and are a matter of concern warranting further investigation. © 2017 John Wiley & Sons A/S.

Primary care providers in safety-net settings often do not have time to discuss advance care planning (ACP). Group visits (GV) may be an efficient means to provide ACP education. To assess the feasibility and impact of a video-based website to facilitate GVs to engage diverse adults in ACP. Feasibility pilot among patients who were ≥55 years of age from two primary care clinics in a Northern California safety-net setting. Participants attended two 90-minute GVs and viewed the five steps of the movie version of the PREPARE website ( www.prepareforyourcare.org ) concerning surrogates, values, and discussing wishes in video format. Two clinician facilitators were available to encourage participation. We assessed pre-to-post ACP knowledge, whether participants designated a surrogate or completed an advance directive (AD), and acceptability of GVs and PREPARE materials. We conducted two GVs with 22 participants. Mean age was 64 years (±7), 55% were women, 73% nonwhite, and 55% had limited literacy. Knowledge improved about surrogate designation (46% correct pre vs. 85% post, p = 0.01) and discussing decisions with others (59% vs. 90%, p = 0.01). Surrogate designation increased (48% vs. 85%, p = 0.01) and there was a trend toward AD completion (9% vs. 24%, p = 0.21). Participants rated the GVs and PREPARE materials a mean of 8 (±3.1) on a 10-point acceptability scale. Using the PREPARE movie to facilitate ACP GVs for diverse adults in safety net, primary care settings is feasible and shows potential for increasing ACP engagement.

There is paucity of studies examining suicide rates in narrow five-year age-bands after the age of 60 years. This study examined suicide rates in eight five-year age-bands between the age of 60 and 99 years because this will allow more precise comparison between the young old (60-79 years) and the oldest old (80+ years) age groups. Data on the number of suicides (International Classification of Diseases - ICD-10 codes, X60-84) in each of the eight five-year age-bands between the age-bands 60-64 years and 95-99 years in both gender for as many years as possible from 2000 were ascertained from three sources: colleagues with access to national data, national statisics office websites and email contact with the national statistics offices. The population size for the corresponding years and age-bands was estimated for each country using data provided by the United Nations website. In men, suicide rates continued to increase for each of the seven five-year age-bands from 60-64 years to 90-94 years age-band, and then declined slightly for the 95-99 year age-band. In women, suicide rates continued to increase for each of the six five-year age-bands from 60-64 years to 85-89 years age-bands, and then declined slightly for the 90-94 years and 95-99 years age-bands. The overall global suicide rates for each of the eight five-year age-bands are sufficiently large for them to constitute a public health concern. This is especially important given the ongoing rise in the elderly population size and the paucity of data on risk and protective factors for suicide in the five-year age-bands after the age of 60 years.

Objectives: To investigate the diagnostic accuracy of 64-slice multidetector computed tomography (64-CT) for detection of in-stent restenosis (ISR) in an unselected, consecutive patient population. Background: Detection of in-stent restenosis by cardiac CT would be a major advance for the evaluation of patients suspected of having ISR. However, the diagnostic accuracy of current generation 64-CT in this context is not fully established. Methods: We conducted a prospective study on patients with stable angina or acute coronary syndrome with no prior history of coronary artery disease. Six months after percutaneous coronary intervention (PCI) with stent placement they underwent a 64-CT scan (Toshiba Multi-Slice Aquilion 64) and consequently a repeat coronary angiography for comparison. Cardiac CT data sets were analyzed for the presence of in-stent restenosis by two independent expert readers blinded to the coronary angiographic data. Results: Ninety-three patients with a total of 140 stents were evaluated. Males comprised 82% of the study group and the mean age was 63 {+-} 10 years. The mean time from PCI to the repeat coronary angiography was 208 {+-} 37 days and the mean time from 64-CT to repeat coronary angiography was 3.7 {+-} 4.9 days. The restenosis rate according to coronary angiography was 26%. Stent diameter, strut thickness, heart rate and body mass index (BMI) significantly affected image quality. The sensitivity, specificity, positive and negative predictive values of 64-CT for detection of in-stent restenosis were 27%, 95%, 67% and 78%, respectively. Conclusions: Current generation, 64-slice CT, remains limited in its ability to accurately detect in-stent restenosis.

One hundred and fifty-three patients with inoperable non-small cell lung cancer (NSCLC) treated with radiotherapy alone have been retrospectively analysed. Normalized Total Dose (NTD) as defined by Macejewski, TN-stage (AJC-system) and histology have been examined with respect to 5-year disease-free survival (DFS) and the patterns of failure so as to identify subgroups of patients that routinely should be treated with radical intent. The 5-year DFS for T1, 2-N0, 1 and T3-N0, 1 staged patients was 30% (7/23) and 25% (4/16) respectively when the tumor NTD (a/b=10 Gy) was 56-64 Gy vs. 12% (5/41) and 0% (0/10) when the NTD was 48-55 Gy. This difference was statistically significant for the squamous cell histology group. The higher doses significantly altered the patterns of death in N0, 1 staged squamous cell carcinoma and adenocarcinoma patients. Forty-five percent (22/55) and 41% (12/29) of squamous cell adenocarcinoma patients respectively, died from local relapse without evidence of distant metastases when NTD less than 55 Gy were given vs. 21% (9/42) and 13% (2/15) when the NTD delivered was 56-64 Gy (p<0.05). Although for N2, 3 staged patients or patients with direct extension of the tumor into the mediastinum death from local relapse occurred in 38% (10/26) of the high NTD treated patients vs. 51% (19/37) of the low-dose treated ones, the difference was not statistically significant. It is concluded that NSCLC patients should not a priori be considered as non-radiocurable. At least 30% of the patients with early local stages can be long-term disease-free survivors with readiation NTD up to 60 Gy and better results are to be expected with higher doses. Advanced T-stage without mediastinal involvement should be treated with radical intent since a high NTD could give cure rates of over 25%. The disappointing results for patients with mediastinal disease could perhaps be attributed to the low NTD delivered. For patients with good performance status

The Hamamatsu UV-light enhanced 64-channel SiPM array of the newest generation (S13361-3050AS-08) has been examined for the purpose of being used for the Silicon Elementary Cell Add-on (SiECA) of the EUSO-SPB balloon experiment. At a room temperature of 19 . 5 °C, the average measured breakdown voltage of the array is (51 . 65 ± 0 . 11) V, the average gain is measured to (2 . 10 ± 0 . 07) ṡ 106 and the average photon detection efficiency results to (44 . 58 ± 1 . 80) % at a wavelength of (423 ± 8) nm and a bias voltage of 55 . 2V. The average dark-count rate is (0 . 69 ± 0 . 12) MHz, equivalent to a dark count rate per SiPM area of (57 ± 12) kHz /mm2, and the crosstalk probability is measured to (3 . 96 ± 0 . 64) %. These results confirm the information given by the manufacturer. Measurements performed with the newly installed Single Photon Calibration Stand at KIT (SPOCK) show the improved sensitivity to photons with wavelengths lower than 400 nm compared to the SiPM array S12642-0808PA-50, which was also investigated for comparison. Additional measurements confirm the strong temperature dependence of the SiPM characteristics as given in the data sheet. All the characterized parameters appear to be sufficiently uniform to build up a focal surface of SiPM arrays fulfilling the requirements for a telescope detecting photons in the UV range.

Full Text Available The conventional asphalt road has almost been considered fail to serve the transportation needs. It is indicated by the occurrence of premature damage which is caused by vehicle load and climate. Starbit E-55, the polymer modified bitumen, is formulated to meet the requirement of transport development. Considering those needs, it is important to investigate the feasibility level of that modified bitumen as alternate asphalt instead of the conventional one. This research began with the measurement of the properties of hard layered AC-WC Starbit E-55, then comparing the result to 60/70 penetration of Pertamina asphalt. The next step is then, to determine the converted value so as to be close to that of Pertamina (60/70 penetration. This step is conducted by applying durability and ITS tests on the mixture. Result of the tests showed that hard layered AC-WC Starbit E-55 has better characteristic at 5.7% optimum level asphalt and 6.4% of Pertamina asphalt (60/70 penetration. Starbit E-55 converted level within hard-layered ACWC is 5.6%. The performance test result on immersion with variance of 1, 3, 5, 7 and 14 days shows that durability value of Starbit E-55 AC-WC has better performance. During the process, Starbit E-55 required 15.38% higher energy consumption.

Full Text Available The objective of this study is to analyze gender differences in HIV-related practices in the Brazilian population. A national survey was carried out in 2008 with a sample size of 8,000 individuals aged 15-64 years old. The sampling was stratified by macro geographical region and urban/rural areas. Logistic regression models were used to investigate the main predictors of consistent condom use. The results showed that women have less sexy, start sexual life later than men, have fewer casual sexual partners, but use condom less frequently than men. On the other hand, the coverage of HIV testing is significantly greater among women. Significant differences by gender were seen in all HIV-related risky practices. The greater vulnerability was always associated with women, with exception of HIV testing. The low proportion of condom use in infidelity situations was a problem for box sexes and deserves special consideration when developing prevention strategies.

Kawasaki disease (KD) is a systemic vasculitis that mainly affects coronary arteries in children, and requires regular follow-up from the time of diagnosis. To evaluate the feasibility of 64-slice CT angiography (CTA) for follow-up of patients with KD using previously performed invasive catheter coronary angiography (CCA) as reference standard. The study group comprised 12 patients (age 17.6 {+-} 2.9 years, mean{+-}SD) with a diagnosis of KD and a previously performed CCA (interval, 32.6 {+-} 13.5 months) who underwent 64-slice cardiac CTA. The quality of the images for establishing the presence of coronary abnormalities was determined by two observers. The CTA findings were compared with those from the prior CCA. Adequate image quality was obtained in all patients. Mean effective dose for CTA was 6.56 {+-} 0.95 mSv. CTA allowed accurate identification, characterization and measurement of all coronary aneurysms (n = 32), stenoses (n = 3) and occlusions (n = 9) previously demonstrated by CCA. One patient with disease progression went on to have percutaneous coronary intervention. Coronary lesions were reliably evaluated by 64-slice CTA in the follow-up of compliant patients with KD, reducing the need for repeated diagnostic invasive CCA. Hence, in an adequately selected patient population, the role of CCA could be limited almost only to therapeutic procedures. (orig.)

Full Text Available Abstract Background: One of the common and important health problems is failure to thrive in childhood. The purpose of this study was to determine the effect of education on preventive behaviors of failure to thrive in mothers with children based on health belief model. Materials and Methods: This study is an interventional one in which 100 mothers with children one to five years involved (samples divided into two case and control groups, each of 50 sampling was done by a simple random method. For collecting information, a researcher-made questionnaire based on the health belief model and performance check list were used. Then, case group was trained for one month. 3 months after training, data were gathered and analyzed by Spss20 software. In addition to descriptive statistics, tests such as Chi-square, paired t-test and independent T-test were used. Results: The mean age of case and control was 29.98±5.51 and 25.35±5.30 years old, respectively. The average age of children was 23.31 ± 13.14 and 27.55 ± 14.01months, respectively. Before the intervention, no significant difference was seen between groups. The average score in case group before intervention was as: knowledge(31.87±14.24, perceived susceptibility(64.23±5.86, perceived severity(64.41±9.34, perceived benefits(61.75±6.79, perceived barriers(67.91±8.14, self-efficacy(68.00±7.87, cues to action(44.53±6.82 and action(70.00±9.77. However, after the intervention, significant differences between groups in all variables were obserred. Conclusion: According to the results, education based on health belief model is recommended for promoting preventive behaviors of failure to thrive.

2013-01-01

Objective: To determine the frequency of Pap smear testing among women and to evaluate their level of knowledge about the test and other relevant factors. Methods: The study comprised women who presented to the Gynaecology and Obstetrics Polyclinic of Sakarya Training and Research Hospital, Turkey, between April 1 and 30, 2012. The questionnaire was developed in line with the objectives of the study. They were filled by the participants who were supervised during the process. Women who had had at least one Pap smear test in life were considered to have taken a Pap smear test , and those who had heard of the test were accepted as women who k new of the Pap smear test . Data was analysed using SPSS 15.0. Chi-square test was used for analyses, and statistical significance was set at p<0.05. Results: The age of 601 subjects ranged between 15 and 64 years, with a mean of 31.09+-10.49 years. Of the total, 115 (19.1%) had taken a Pap smear test before and 293 (48.8%) knew of the test. The proportion of the women who had had a Pap smear test was higher among those who were over 30 years of age (n=73; 63.47%), had post-high school educational degrees (n=68; 59.13%), had moderate familial income status (n=74; 64.34%), were married (n=109; 94.78%), had first sexual experience after 25 years of age(n=42; 36.52%), and were not using a contraceptive method (n=97; 84.34%) (p<0.05 for each). Besides, more women with previous knowledge of the test had taken the test (p<0.05). Conclusion: The subjects did not have sufficient information on Pap smear and the frequency of having a test was low. Raising awareness would prove beneficial. (author)

ST segment depression and the T wave abnormalities (myocardial ischemia occurred more often in women than in men (6.9% vs 5.1%, respectively; p<0.001, with a significant increase of these changes in women after 60 years old. The prevalence of ECG abnormalities increases with age. Significant rise of ECG-changes prevalence was found in men at the age of 55-59 years (pathological QQS, myocardial ischemia, left ventricular hypertrophy; and in women – at 60-64 years (myocardial ischemia, atrial fibrillation, conduction abnormalities. Almost two-fold increase in the incidence of arrhythmias and conduction abnormalities was found in men and women aged 60-64 years, regardless of employment status.Conclusion. Given the poor prognosis of ischemic ECG abnormalities, even their low prevalence indicates to unfavorable epidemiological situation among people around retirement age (55-64. These results emphasize the need for practitioners to careful attention to the ECG-abnormalities with poor prognosis in patients pre-retirement and retirement age. They may also be useful for practical public health as a

Newborn chicks are susceptible to Salmonella enterica serovar Enteritidis (SE). The objective of this study was to evaluate the effect of Lactobacillus probiotic isolated from chicken feces on heterophil phagocytosis in broiler chicks. A total of 150 newborn broiler chicks were divided into 5 groups (30 chicks per group) as follows: group 1 (normal control), given feed and water only, group 2 (positive control) given feed, water and SE infection, group 3 (L61 treated) given feed, water, SE infection followed by Lactobacillus salivarius L61 treatment, group 4 (L55 treated) given feed, water, SE infection followed by L. salivarius L55 treatment, and group 5 given feed, water, SE infection followed by L. salivarius L61 + L55 combination treatment. After SE infection, L. salivarius treatment lasted for 7 days. The results showed that L. salivarius L61 and L. salivarius L55 treatment, either alone or combination of both, increased the survival rate after SE infection, and upregulated heterophil phagocytosis and phagocytic index (PI). Conversely, chick groups treated with Lactobacillus showed lower SE recovery rate from cecal tonsils than that of the positive control group. The PI values of the chicken group with SE infection, followed by the combination of L. salivarius L61 and L. salivarius L55 were the highest as compared to either positive control or normal control group. Two Lactobacillus strains supplementation group showed significantly (p<0.05) higher PI value at 48 h than 24 h after treatment.

Background and purpose - The treatment of patients between 55 and 70 years with displaced intracapsular femoral neck fracture remains controversial. We compared internal fixation (IF), bipolar hemiarthroplasty (HA) and total hip arthroplasty (THA) in terms of mortality, reoperations and patient-reported outcome by using data from the Norwegian Hip Fracture Register. Patients and methods - We included 2,713 patients treated between 2005 and 2012. 1,111 patients were treated with IF, 1,030 with HA and 572 patients with THA. Major reoperations (defined as re-osteosynthesis, secondary arthroplasty, exchange, or removal of prosthesis components and Girdlestone procedure), patient-reported outcome measures (satisfaction, pain, and health-related quality of life (EQ5D) after 4 and 12 months), 1-year mortality, and change in treatment methods over the study period were investigated. Results - Major reoperations occurred in 27% after IF, 3.8% after HA and 2.8% after THA. 549 patients (20% of total study population) answered both questionnaires. Compared with IF, patients treated with THA were more satisfied after 4 and 12 months, reported less pain after 4 months and 12 months, had a higher EQ5D-index score after 4 months and 12 months, and EQ-VAS score after 4 months. Compared with IF, patients treated with HA were more satisfied and reported less pain after 4 months. EQ5D-index and EQ-VAS were similar. Patients treated with HA had higher 1-year mortality and had more comorbidities than both the THA and IF group. All these differences were statistically and clinically significant. Interpretation - This study showed high reoperation rate after IF and better patient-reported outcome after both THA and HA with medium follow-up. Patients selected for HA represented a frailer group than patients treated with THA or IF.

A missence mutation Trp64Arg in the beta3-adrenergic receptor gene is associated with obesity, insulin resistance, a lower metabolic rate and the earlier onset of NIDDM but the published results are controversial. We investigated the effect of this mutation on insulin resistance (euglycemic hyperinsulinemic clamp), on fat mass and fat distribution (anthropometry, bioimpedance, CT) and resting metabolic rate (indirect calorimetry), lipid spectrum and other metabolic disturbances in Czech juveniles recruited from juvenile hypertensives (H, n = 68) and controls (C, n = 81). The frequency of this mutation (determined by digestion of 210 bp PCR product with MvaI) was double in H than in C (14.7%, vs. 7.4%) and the carriers of Arg64 allele had sig. higher fasting glucose (H: p = 0.002. C: p = 0.025). Four Trp64/Arg64 and six Trp64/Trp64 men (age 23 +/- 4.2, vs. 22.5 +/- 1.9 y, BMI 26 +/- 5.5, vs. 22.9 +/- 5.1 kg/m2) took part in a detailed pilot study. But no signif. differences (Horn's method) in fasting glucose (4.6 +/- 0.6, vs. 4.9 +/- 0.4 mmol/l), in parameters of insulin resistance (M-value150-180 min. 9.1 +/- 1.1, vs. 8.9 +/- 1.5 mg glucose/kg.min(-1)), resting metabolic rate/lean body mass (RMR/kg LBM: 78.6 +/- 4.6, vs. 85.6 +/- 23.2 kJ/kg), lipid spectrum and other screened parameters were found. The lowest resting metabolic rate (RMR/kg LBM 55.4; 62.6 kJ/kg) was found in brothers (both C, Trp64/Trp64) who highly differ in body constitution (BMI 19.0 resp. 32.4 kg/m2). We suppose that in this case the energy metabolism is probably determined by other genetic loci and does not correlate with body fat mass. Our pilot study does not confirm the influence of Trp64Arg mutation in heterozygous carriers on insulin resistance, energy metabolism and lipid spectrum.

LM1-64: a Newly Reported Lmc-Pn with WR Nucleus

Pena, M.; Olguin, L.; Ruiz, M. T.; Torres-Peimbert, S.

1993-05-01

The object LM1-64 was reported by Lindsay & Mullan (1963, Irish Astron. J., 5, 51) as a probable PN in the LMC. Optical and UV spectra taken by us confirm that suggestion. LM1-64 is a high excitation planetary nebulae which shows evidence of having a WC central star. Broad stellar emission at lambda 4650 is detected in the optical spectrum obtained with the CTIO 4m telescope, in 1989. A UV spectrum in the range from 1200 Angstroms to 2000 Angstroms was obtained with IUE in 1990. We have measured all the emission line fluxes available and determined values for the physical conditions and chemical abundances of the nebular ionized gas. The derived values are T(OIII) = 14000K, log He/H = 11.05, log C/H = 9.48, log O/H = 8.55 and log Ne/H = 7.94. LM1-64 shows a large C enhancement in the envelope as result of the central star activity, while He, O and Ne are comparable to the average values reported for the LMC-PNe (Monk, Barlow & Clegg, 1988, MNRAS, 234, 583). We have estimated the He II Zanstra temperature of the central star to be ~ 80,000 K. This temperature is much higher than the values reported for the known LMC-PNe with WR nucleus that Monk et al. have classified as W4 to W8. The only other high temperature WR nucleus in a LMC-PN is N66 which recently showed evidence of undergoing a WR episode (Torres-Peimbert, Ruiz, Peimbert & Pe\\ na, 1993, IAU Symp. 155, eds. A. Acker & R. Weinberger, in press).

2014-01-01

A recent Korea National Health and Nutrition Survey indicated inadequate riboflavin intake in Koreans, but there is limited research regarding riboflavin status in South Korea. The purpose of this study was to determine riboflavin intake and status of Korean adults. Three consecutive 24-h food recalls were collected from 412 (145 men and 267 women) healthy adults, aged 20–64 years, living in South Korea and urine samples were collected from 149 subjects of all subjects. The dietary and total (dietary plus supplemental) riboflavin intake was 1.33 ± 0.34 and 2.87 ± 6.29 mg/day, respectively. Approximately 28% of the subjects consumed total riboflavin less than the Estimated Average Requirement. Urinary riboflavin excretion was 205.1 ± 190.1 μg/g creatinine. Total riboflavin intake was significantly positively correlated to the urinary riboflavin excretion. (r = 0.17171, p = 0.0363). About 11% of the Korean adults had urinary riboflavin riboflavin deficiency and 21% had low status of riboflavin (27 μg/g creatinine ≤ urinary riboflavin riboflavin status. In some adults in Korea, consumption of riboflavin-rich food sources should be encouraged. PMID:25558909

To assess the diagnostic value of ultrasound compared to CT in evaluating acute abdominal pain of different causes in children 10 years of age and under, hospital records and imaging files of 4052 patients under age of 10 who had imaging for abdominal pain were reviewed. One-hundred-thirty-two patients (3 %), (74 males/58 females) who underwent ultrasound and CT within 24 h were divided by age: group I, ages 0-48 months (25 patients); group II, 49-84 months (53 patients); and group III, 85-120 months (54 patients). Diagnoses at ultrasound, CT, and discharge were compared. Cases of a change in diagnosis following CT and impact of the changed diagnosis on patient management were assessed. Non-diagnostic ultrasound or a diagnostic conundrum was present in a small percentage (3 %) of our patients. In the group of patients imaged with two modalities, CT changed the diagnosis in 73/132 patients (55.3 %). Patient management changed in 63/132 patients (47.7 %). CT changed the diagnosis in 46/64 patients with surgical conditions (71.8 %, p diagnostic or equivocal US in a small percentage of patients is probably sufficient to justify the additional radiation burden.

To observe the short and long-term efficacy of quick repositioning maneuver for posterior semicircular canal benign paroxysmal positional vertigo (PC-BPPV) in different age groups. The clinical data of 113 adult patients with single PC-BPPV who underwent quick repositioning maneuver from July 2009 to February 2015 were retrospectively analyzed. The quick repositioning maneuver was to roll the patient from involved side to healthy side in the coronal plane for 180° as quickly as possible. The patients were divided into 3 groups according to different ages: young group (age group (45 ≤ age group (≥ 60 years). The short and long term outcomes of the three groups were observed. The left ear was involved in 58 cases (51.3%) and the right ear in 55 cases (48.7%). The short term improvement rates of the young, middle-age and the old groups were 92.5%, 93.6% and 92.3% respectively, and the long term improvement rate was 90.0%, 85.1% and 73.1% respectively. There was no significant difference among the three groups in short and long term outcomes (P > 0.05). The recurrence rate of the three groups was 5.0%, 6.4% and 15.4% respectively, also no significant difference (P > 0.05). The quick repositioning maneuver along the coronal plane for PC-BPPV has a definite effect for every age groups. The method is simple, rapid and easy to master, and the patients are tolerated the maneuver well without evident side effect.

The purpose of this study was to analyze the prevalence, demographic patterns and management of odontogenic infections in patients undergoing treatment in an outpatient dental emergency service of a university hospital. In a retrospective study of the year 2012, all patients suffering from odontogenic infections were included. Demographic data, diagnosis and the conducted treatment were analyzed. Odontogenic infections were defined as pulpitis, apical and marginal periodontitis, abscesses and pericoronitis. A total of 2,058 out of 4,209 emergency patients suffered from odontogenic infections. The majority (45.0%) had an apical periodontitis, 20.8% abscesses, 17.3% a marginal periodontitis, 16.3% a pulpitis and 5.8% a pericoronitis. Mean age was 37.5 ± 17.0 years standard deviation (SD) (1.2-96.4). Most patients were 20 to 29 years (24.6%), followed by the age group of 30 to 39 year old patients (21.0%). Males were affected more frequently (55.5%) than females (45.5%). Most of the patients (64.5%) of the patients received a dental or surgical treatment. Antibiotics were prescribed in 31.7% of cases. Amoxicillin was the most common prescribed antibiotic (54.5%). Odontogenic infections represent one of the main reasons for consulting the emergency service. Due to the high number of cases and the severe complications, dentists have to be familiar with the surgical management of odontogenic infections as well as the appropriate use of antibiotics. Nearly half of all patients who sought, treatment in the emergency service had an odontogenic infectious disease. This should be considered for the organization and planning of the service.

Multislice computed tomography (MSCT) for the noninvasive detection of coronary artery stenoses is a promising candidate for widespread clinical application because of its non-invasive nature and high sensitivity and negative predictive value as found in several previous studies using 16 to 64 simultaneous detector rows. A multi-centre study of CT coronary angiography using 16 simultaneous detector rows has shown that 16-slice CT is limited by a high number of nondiagnostic cases and a high false-positive rate. A recent meta-analysis indicated a significant interaction between the size of the study sample and the diagnostic odds ratios suggestive of small study bias, highlighting the importance of evaluating MSCT using 64 simultaneous detector rows in a multi-centre approach with a larger sample size. In this manuscript we detail the objectives and methods of the prospective ''CORE-64'' trial (''Coronary Evaluation Using Multidetector Spiral Computed Tomography Angiography using 64 Detectors''). This multi-centre trial was unique in that it assessed the diagnostic performance of 64-slice CT coronary angiography in nine centres worldwide in comparison to conventional coronary angiography. In conclusion, the multi-centre, multi-institutional and multi-continental trial CORE-64 has great potential to ultimately assess the per-patient diagnostic performance of coronary CT angiography using 64 simultaneous detector rows.

To evaluate whether late-career unemployment is associated with increased all-cause mortality, functional disability, and depression among older adults in Taiwan. In this long-term prospective cohort study, data were retrieved from the Taiwan Longitudinal Study on Aging. This study was conducted from 1996 to 2007. The complete data from 716 men and 327 women aged 50-64 years were retrieved. Participants were categorized as normally employed or unemployed depending on their employment status in 1996. The cumulative number of unemployment after age 50 was also calculated. Logistic regression analysis was used to examine the effect of the association between late-career unemployment and cumulative number of late-career unemployment on all-cause mortality, functional disability, and depression in 2007. The average age of the participants in 1996 was 56.3 years [interquartile range (IQR)=7.0]. A total of 871 participants were in the normally employed group, and 172 participants were in the unemployed group. After adjustment of gender, age, level of education, income, self-rated health and major comorbidities, late-career unemployment was associated with increased all-cause mortality [Odds ratio (OR)=2.79; 95% confidence interval (CI)=1.74-4.47] and functional disability [OR=2.33; 95% CI=1.54-3.55]. The cumulative number of late-career unemployment was also associated with increased all-cause mortality [OR=1.91; 95% CI=1.35-2.70] and functional disability [OR=2.35; 95% CI=1.55-3.55]. Late-career unemployment and cumulative number of late-career unemployment are associated with increased all-cause mortality and functional disability. Older adults should be encouraged to maintain normal employment during the later stage of their career before retirement. Employers should routinely examine the fitness for work of older employees to prevent future unemployment. Copyright © 2016. Published by Elsevier Ireland Ltd.

Cu-64-pyruvaldehyde-bis-(N4-methylthiosemicarbazide) or Cu-64-PTSM as tracer for brain positron emission tomography

Synthesis of pyruvaldehyde-bis-(N 4 -methylthiosemicarbazide) (PTSM), used for medical investigation and diagnosis, has been carried out in our Radiopharmaceutical Division in C.A.E. (Ezeiza Atomic Center). PTSM has been obtained introducing modifications to a previous synthesis published by H.G. Petering. (M.P. 236-238 degrees C). TLC, HPLC and IR spectrum controls have been performed. Cu-64 can be obtained by the Cu-63(n,α) and Zn-64(n,p) reactions. This last reaction has been chosen for the production in the RA-3 reactor since it leads to Cu-64 of high specific activity. Two different assays have been performed to obtain the chelate PTSM-Cu-64. The first one has been obtained by buffering the Cu-64 to pH 3-4; adding the PTSM solution to ethanol. The second assay has been carried out by buffering the Cu-64 solution with sodium acetate 3M and adding 100 μl of PTSM solution. Biodistribution studies have been carried out on NIH and rats showing a brain uptake of 4%, 30 minutes after injection. Thus, PTSM-Cu-64 proves a good brain diagnosis agent. (author). 1 ref

While many studies show a correlation between chronological age and physiological indicators, the nature of this correlation is not fully understood. To perform a comprehensive analysis of the correlation between chronological age and age-related physiological indicators. Physiological aging scores were deduced using principal component analysis from a large dataset of 1,227 variables measured in a cohort of 4,796 human subjects, and the correlation between the physiological aging scores and chronological age was assessed. Physiological age does not progress linearly or exponentially with chronological age: a more rapid physiological change is observed around the age of 55 years, followed by a mild decline until around the age of 70 years. These findings provide evidence that the progression of physiological age is not linear with that of chronological age, and that periods of mild change in physiological age are separated by periods of more rapid aging. © 2015 S.

Full Text Available Objective. To study the prevalence of social support (SS and its influence on the relative risk (RR of myocardial infarction (MI and stroke in the female population aged 25–64 in Russia. Materials and methods. Under the third screening of the WHO “MONICA-psychosocial” programme, a random representative sample of women aged 25–64 (n=870 were surveyed in Novosibirsk. SS was measured according to the methods of the Berkman–Sym test [indices of close contacts (ICC and index of social network (SNI]. From 1995 to 2010, women were followed for 16 years to observe the incidence of MI and stroke. Results. The prevalence of low levels of ICC and SNI in women aged 25–64 was 57.1 and 77.7%, respectively. Low levels of ICC and SNI were associated with poor self-rated health and awareness about their health, adverse behavioural habits, high job strain and family stress. Rates of MI and stroke development were higher in married women with low ICC and SNI who were being in class “hard manual work”. Over a 16-year study period, the RR of MI in women with low ICC compared to those with high ICC was 4.9 times higher, and the risk of stroke was 4.1 times higher. Low level of SNI increased MI risk in 2.9 times, risk of stroke in 2.7 times. Conclusions. Majority of women aged 25–64 years in Russia have low social support which is associated with poor self-rated health, low awareness about the health that increases the risk of MI and stroke in 2.7–4.9 times in groups of “married” and “hard physical work”.

Gender differences in play behavior and physical aggression have been consistently reported. Theoretical perspectives concerning evolutionary, social, and social-cognitive mechanisms suggest that male-typical play behavior during childhood increases subsequent physical aggression. The evidence supporting these connections is limited, however. The present study investigated the association between gender-typed play behavior in early childhood and physical aggression in early adolescence using a sample drawn from a longitudinal, population study, the Avon Longitudinal Study of Parents and Children. Based on gender-typed play behavior as measured by the Pre-School Activities Inventory at age 3.5 years, samples of masculine (64 boys, 60 girls), feminine (80 boys, 66 girls), and randomly selected control children (55 boys, 67 girls) were recruited at age 13 years and administered the Reinisch Aggression Inventory. After controlling for a range of sociodemographic variables, maternal characteristics, and behavioral problems, including hyperactivity and conduct problems at age 3.5, significant group differences in physical aggression at age 13 were found among children classified as masculine, control, and feminine at age 3.5. Masculine children exhibited significantly more physical aggression than control children or feminine children, and control children exhibited significantly more physical aggression than feminine children. The association between gender-typed play behavior and physical aggression was not moderated by sex. These results suggest that the degree of childhood gender-typed play behavior independently predicts the degree of physical aggression at adolescence in boys and in girls.

The aim of this retrospective study was to evaluate endometriosis in adolescent and young girls and further to review the menstrual, reproductive characteristics, and risk factors. We reviewed the medical records of adolescent and young girls with endometriosis from 2 different countries. Data were collected and analyzed from charts of 900 patients with endometriosis. Fifty-five female adolescents aged between 13 and 21 years (mean age 18.3 years) participated in our series. This study was conducted in the Obstetric and Gynecology Department of Venizeleio General Hospital of Crete and involved all patients diagnosed with endometriosis between 1996 and 2016. Statistical methods included χ 2 and Mann-Whitney U test. Of 900 patients with endometriosis we found 55 female adolescents (6.1%). The mean age was 18.3 ± 2.3 years, significantly younger compared with the advanced endometriosis patients (32.7 ± 7.2; P endometriosis group. The factors associated with an increased risk for young women include age at menarche, dysmenorrhea, history of asthma, and a positive family history of endometriosis. Additionally, we report on 16 of 55 (32%) adolescent women with endometriosis and congenital malformations (P endometriosis in adolescent and young women and risk factors including early menarche, early onset of dysmenorrhea, history of asthma, previous surgical procedures, obstructive genital anomalies, and family history of endometriosis.

Low-temperature Fourier transform infrared (FTIR) and UV difference spectroscopies combined with selective tyrosine nitration and tyrosine isotopic labeling have been used to investigate the participation of tyrosines-26 and -64 in the bacteriorhodopsin (bR) photocycle. Nitration of Tyr-26 has no detectable effect on the FTIR or UV difference spectra of the BR 570 → K 630 or BR 570 → M 412 transitions. In contrast, nitration of Tyr-64 causes changes in both the FTIR and UV spectra of these transitions. However, this nitration does not alter tyrosine peaks in the FTIR difference spectra which have previously been associated with the protonation of a tyrosinate by K 630 and the deprotonation of a tyrosine by M 412 . Instead, Tyr-64 nitration appears to affect other tyrosine peaks. These results and changes in UV difference spectra upon Tyr-64 nitration are consistent with the deprotonation of Tyr-64 by M 412 as concluded previously. Effects on chromophore vibrations caused by Tyr-64 nitration are unaltered upon reducing the nitrotyrosine to aminotyrosine with sodium dithionite. Finally, nitro-Tyr-64 causes a shift in the frequency of a positive peak at 1739 cm -1 in the BR 570 → M 412 FTIR difference spectrum which reflects the protonation of a carboxyl-containing residue. The shift does not occur for samples containing amino-Tyr-64. These data suggest that Tyr-64 may interact with this carboxyl group

This chapter on wildlife underpasses on U.S. Highway 64 in North Carolina is from a book on highways, wildlife, and habitat connectivity. U.S. 64 is an important route in North Carolina connecting major population centers and highways that underwent a major upgrade from a two-lane rural road to a major highway. New routes were proposed for a large portion of the project (28 miles) to improve driver safety and increase speed limits to 70 miles per hour (from the previously posted 55 mph). The authors review the geographical, historical, political, and social setting; the roadway and environmental issues; the rationale for the project; critical factors; outcomes of the project; and lessons learned. The area of the project supports high wildlife densities, including American black bears, white-tailed deer, red wolves, and bobcats. Critical factors to be incorporated into wildlife mitigation measures: driver safety, underpass construction costs, and permitting by the U.S. Fish and Wildlife Service and the U.S. Army Corps of Engineers. The U.S. 64 underpasses, completed in 2005, were the first in North Carolina designed specifically for wildlife and according to specifications provided by the North Carolina Wildlife Resources Commission (NCWRC). The authors describe the underpass specifications recommended based on this project, including size, control of public access, fencing, gates, and maintenance (notably vegetation management). The authors conclude that one of the most beneficial outcomes of this project was the fact that, since the completion of the U.S. 64 underpasses, the North Carolina Department of Transportation (NCDOT) routinely considers wildlife passageways for road projects in the state.

The short-lived (12.7 h half-life) {sup 64}Cu radioisotope is both a {beta} {sup +} and a {beta} {sup -} emitter. This property makes {sup 64}Cu a promising candidate for novel medical applications, since it can be used simultaneously for therapeutic application of radiolabelled biomolecules and for diagnosis with PET. Following previous work on {sup 64}Cu production by deuteron irradiation of natural zinc, we report here the production of this radioisotope by deuteron irradiation of enriched {sup 64}Zn. In addition, yields of other radioisotopes such as {sup 61}Cu, {sup 67}Cu, {sup 65}Zn, {sup 69m}Zn, {sup 66}Ga and {sup 67}Ga, which were co-produced in this process, were also measured. The evaporation code ALICE-91 and the transport code SRIM 2003 were used to determine the excitation functions and the stopping power, respectively. All the nuclear reactions yielding the above-mentioned radioisotopes were taken into account in the calculations both for the natural and enriched Zn targets. The experimental and calculated yields were shown to be in reasonable agreement. The work was carried out at the Scanditronix MC-40 Cyclotron of the Institute for Health and Consumer Protection of the Joint Research Centre of the European Commission (Ispra site, Italy). The irradiations were carried out with 19.5 MeV deuterons, the maximum deuteron energy obtainable with the MC-40 cyclotron.

Ready a Commodore 64 retrospective

CERN Document Server

Dillon, Roberto

2015-01-01

How did the Commodore 64 conquer the hearts of millions and become a platform people still actively develop for even today? What made it so special? This book will appeal to both those who like tinkering with old technology as a hobby and nostalgic readers who simply want to enjoy a trip down memory lane. It discusses in a concise but rigorous format the different areas of home gaming and personal computing where the C64 managed to innovate and push forward existing boundaries. Starting from Jack Tramiel's vision of designing computers "for the masses, not the classes," the book introduces the 6510, VIC-II and SID chips that made the C64 unique. It briefly discusses its Basic programming language and then proceeds to illustrate not only many of the games that are still so fondly remembered but also the first generation of game engines that made game development more approachable − among other topics that are often neglected but are necessary to provide a comprehensive overview of how far reaching the C64 in...

In-111 ((111)In)-labeled octreotide has been clinically used for imaging somatostatin receptor-positive tumors, and radiolabeled octreotide analogs for positron emission tomography (PET) have been developed. Cu-64 ((64)Cu; half-life, 12.7 h) is an attractive radionuclide for PET imaging and is produced with high specific activity using a small biomedical cyclotron. The aim of this study is to produce and fundamentally examine a (64)Cu-labeled octreotide analog, (64)Cu-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid-D: -Phe(1)-Tyr(3)-octreotide ((64)Cu-DOTA-TOC). (64)Cu produced using a biomedical cyclotron was reacted with DOTA-TOC for 30 min at 45 degrees C. The stability of (64)Cu-DOTA-TOC was evaluated in vitro (incubated with serum) and in vivo (blood collected after administration) by HPLC analysis. Biodistribution studies were performed in normal mice by administration of mixed solution of (64)Cu-DOTA-TOC and (111)In-DOTA-TOC and somatostatin receptor-positive U87MG tumor-bearing mice by administration of (64)Cu-DOTA-TOC or (64)Cu-1,4,8,11-tetraazacyclotetradecane-1,4,8,11-tetraacetic acid-octreotide ((64)Cu-TETA-OC). The tumor was imaged using (64)Cu-DOTA-TOC, (64)Cu-TETA-OC, and FDG with an animal PET scanner. (64)Cu-DOTA-TOC can be produced in amounts sufficient for clinical study with high radiochemical yield. (64)Cu-DOTA-TOC was stable in vitro, but time-dependent transchelation to protein was observed after injection into mice. In biodistribution studies, the radioactivity of (64)Cu was higher than that of (111)In in all organs except kidney. In tumor-bearing mice, (64)Cu-DOTA-TOC showed a high accumulation in the tumor, and the tumor-to-blood ratio reached as high as 8.81 +/- 1.17 at 6 h after administration. (64)Cu-DOTA-TOC showed significantly higher accumulation in the tumor than (64)Cu-TETA-OC. (64)Cu-DOTA-TOC PET showed a very clear image of the tumor, which was comparable to that of (18)F-FDG PET and very similar to that of (64)Cu

Due to the feature of high hydrolysis, tannase is widely used in food, beverage, brewing and other fields. However, high cost in producing natural tannase makes it difficult to apply tannase to industry in a large-scale. Microbial expression systems can be used for preparing numerous amount of enzyme at low cost, so in this paper Aspergillus niger N5-5 was expressed using E. coli system. Specific primers were designed based on the Aspergillus niger N5-5 sequence N3 (GenBank, No.: KP677552), and tannase gene tan was promoted to carry 6 His tag and enzyme cutting site which contains NdeI/HindIII using PCR amplification. Then, tannase gene tan was connected to expression vector by NdeI/HindIII enzyme cutting. In this way, recombinant expression vector tan -pET43.1a was formed. Then, the expression vector pET43.1a by NdeI/HindIII enzyme cutting was transformed into E. coli BL21 (DE3) to induce expression of Aspergillus niger N5-5. When the induced fungi were disrupted by the ultrasonic wave, the crude enzyme was extracted and purified by using the IMAC, and then the activity of the crude enzyme and pure enzyme was determined. According to the results of determination of the tannase activity, the tannase activity of the crude enzyme was greatly improved after the crude enzyme was purified, and the specific activity of the pure enzyme was about 8 times of that of the crude enzyme. The results of SDS-PAGE of the pure enzyme showed that the molecular mass of the pure enzyme was about 65 kDa/64-65 kDa, which was consistent with the expected result (64.2 kDa), It can be concluded that the crude enzyme solution was purified successfully. The results of pure enzyme's protein identification by Western Blotting showed that clear protein bands pro -3 were observed. Molecular mass of clear protein bands pro-3 was about 65 kDa, which was in line with the expected results (64.2 kDa). It can be seen that the aforementioned expression protein could be specifically combined

This proposal seeks support to increase our production of the radionuclides yttrium-86 and zirconium-89 while continuing to produce copper-64. We have the advantage that we already ship out copper-64 to some 20-25 institutions per week (over 60 different institutions total including 4 Canadian sites) and thus our group already has significant experience with producing, purifying and shipping radioactive materials. A significant portion of the funds requested supported the purchase of a new hotcell for the production of zirconium-89 and yttrium-86.

Full Text Available Our purpose is to study the effect of different component ratio of Astragalus Total Saponins (ATS and Verbena Total Glycosides (VTG on the cerebral infarction area and the serum biochemical indicators in the focal cerebral ischemia-reperfusion rat model. Compared with the model group, different component ratio of ATS and VTG could significantly improve the neurological deficit scores to the focal cerebral ischemia-reperfusion rat model, and the group of 7:3, 6:4, 5:5 got the best results; it could reduce the mortality of rat model to a certain extent, and the group of 5:5 group got the best results; it can significantly reduce the cerebral infarction area, and the group of 7:3, 5:5, 4:6 got the best results; it could significantly reduce the content of TNF-α, and the group of 8:2, 6:4 got the best results; it could significantly reduce the content of NO, and the group of 7:3, 5:5 got the best results; it could significantly increase the content of SOD, and the group of 6:4, 5:5 got the best results. This indicates that different component ratio of ATS and VTG may protect the damage of focal cerebral ischemia-reperfusion rat model to a certain extent, which are compared using the comprehensive weight method and the ratio of 5:5 was proved to be the optimal active ratio.

Socioeconomic status and self-reported asthma in Indigenous and non-Indigenous Australian adults aged 18-64 years: analysis of national survey data

Cunningham Joan

2010-08-01

Full Text Available Abstract Background Asthma is more common among Indigenous than non-Indigenous Australian adults, but little is known about socioeconomic patterning of asthma within the Indigenous population, or whether it is similar to the non-Indigenous population. Methods I analysed weighted data on self-reported current diagnosed asthma and a range of socio-economic and demographic measures for 5,417 Indigenous and 15,432 non-Indigenous adults aged 18-64 years from two nationally representative surveys conducted in parallel by the Australian Bureau of Statistics in 2004-05. Results Current asthma prevalence was higher for Indigenous than non-Indigenous people in every age group. After adjusting for age and sex, main language and place of residence were significantly associated with asthma prevalence in both populations. Traditional SES variables such as education, income and employment status were significantly associated with asthma in the non-Indigenous but not the Indigenous population. For example, age-and sex-adjusted relative odds of asthma among those who did not complete Year 10 (versus those who did was 1.2 (95% confidence interval (CI 1.0-1.5 in the non-Indigenous population versus 1.0 (95% CI 0.8-1.3 in the Indigenous population. Conclusions The socioeconomic patterning of asthma among Indigenous Australians is much less pronounced than for other chronic diseases such as diabetes and kidney disease, and contrasts with asthma patterns in the non-Indigenous population. This may be due in part to the episodic nature of asthma, and the well-known challenges in diagnosing it, especially among people with limited health literacy and/or limited access to health care, both of which are more likely in the Indigenous population. It may also reflect the importance of exposures occurring across the socioeconomic spectrum among Indigenous Australians, such as racism, and discrimination, marginalization and dispossession, chronic stress and exposure to

Ji Young Choi

2014-12-01

Full Text Available A recent Korea National Health and Nutrition Survey indicated inadequate riboflavin intake in Koreans, but there is limited research regarding riboflavin status in South Korea. The purpose of this study was to determine riboflavin intake and status of Korean adults. Three consecutive 24-h food recalls were collected from 412 (145 men and 267 women healthy adults, aged 20–64 years, living in South Korea and urine samples were collected from 149 subjects of all subjects. The dietary and total (dietary plus supplemental riboflavin intake was 1.33 ± 0.34 and 2.87 ± 6.29 mg/day, respectively. Approximately 28% of the subjects consumed total riboflavin less than the Estimated Average Requirement. Urinary riboflavin excretion was 205.1 ± 190.1 μg/g creatinine. Total riboflavin intake was significantly positively correlated to the urinary riboflavin excretion. (r = 0.17171, p = 0.0363. About 11% of the Korean adults had urinary riboflavin <27 μg/g creatinine indicating a riboflavin deficiency and 21% had low status of riboflavin (27 μg/g creatinine ≤ urinary riboflavin < 80 μg/g creatinine. Thus, one-third of Korean adults in this study had inadequate riboflavin status. In some adults in Korea, consumption of riboflavin-rich food sources should be encouraged.

Distribution of copper-64 in control mice and in mice bearing ascitic Krebs tumor cells

International Nuclear Information System (INIS)

Apelgot, S.; Coppey, J.; Grisvard, J.; Guille, E.; Sissoeeff, I.

1981-01-01

Three to 20 hr after an i.p. injection of 64 Cu (half-life, 12.8 hr) into mice bearing Krebs ascites cells, a high amount of the radioisotope was recovered in the ascites cells themselves. In the control group, the radioisotope was mainly present in the liver. Similar amounts of 64 Cu were recovered in regenerating as well as in normal liver, whereas in the liver of mice bearing ascites cells, this amount was lower by 40 to 50% regardless of the ascitic volume. Thus, the copper metabolism seems to be disturbed at the hepatic level in mice bearing ascites cells. The distribution of 64 Cu was 'analyzed in DNA, RNA, and proteins from cellular lysates fractionated by CsCl gradient. There was a uniform pattern of distribution in the macromolecules from ascites cells, while 64 Cu' was preferentially associated with the protein fraction from liver. Further experiments indicated that, in vivo, 64 Cu was bound to the DNA of ascites cells

Decreased expression or function of UCP3 (uncoupling protein 3) could reduce energy expenditure and increase the storage of energy as fat. Some studies have pointed to a role of UCP3 in the regulation of whole body energy homeostasis, diet induced obesity, and regulation of lipids as metabolic substrates. The C/C genotype of a polymorphism in the UCP3 promoter (-55C-->T) is associated with an increased expression of UCP3 mRNA in muscle. The aim of our study was to investigate the influence of -55CT polymorphism of UCP3 gene on adipocytokines response and weight loss secondary to a hypocaloric diet in obese patients. A population of 107 obese (body mass index >30) nondiabetic outpatients was analyzed in a prospective way. Before and after three months of a hypocaloric diet, an indirect calorimetry, tetrapolar electrical bioimpedance, blood pressure, a serial assessment of nutritional intake with 3-day written food records, and biochemical analysis were performed. The lifestyle modification program consisted of a hypocaloric diet (1520 kcal, 52% of carbohydrates, 25% of lipids and 23% of proteins). The exercise program consisted of aerobic exercise for at least 3 times per week (60 minutes each). The mean age was 49.5+/-34.5 years and the mean BMI 34.5+/-4.8, with 27 males (25.3%) and 80 females (74.7%). Ninety patients (25 males/65 females) (83.6%) had the genotype 55CC (wild group) and 17 patients (2 male/15 females) (16.4%) 55CT (mutant group). The percentage of responders (weight loss) was similar in both groups (wild group: 84.7% vs. mutant group: 81.8%). BMI, weight, fat mass, systolic blood pressure, LDL cholesterol, waist circumference, and waist-to-hip ratio decreased in the wild group and RMR and VO (2) were increased. In the mutant group, BMI and weight decreased. Leptin and IL-6 levels have a significant decrease in the wild group (9.6%: p<0.05) and (30.5%: p<0.05), respectively. Patients with -55CC genotype have a significant decrease in leptin

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

The electrically silent Kv6.4 subunit confers hyperpolarized gating charge movement in Kv2.1/Kv6.4 heterotetrameric channels.

Directory of Open Access Journals (Sweden)

Elke Bocksteins

Full Text Available The voltage-gated K(+ (Kv channel subunit Kv6.4 does not form functional homotetrameric channels but co-assembles with Kv2.1 to form functional Kv2.1/Kv6.4 heterotetrameric channels. Compared to Kv2.1 homotetramers, Kv6.4 exerts a ~40 mV hyperpolarizing shift in the voltage-dependence of Kv2.1/Kv6.4 channel inactivation, without a significant effect on activation gating. However, the underlying mechanism of this Kv6.4-induced modulation of Kv2.1 channel inactivation, and whether the Kv6.4 subunit participates in the voltage-dependent gating of heterotetrameric channels is not well understood. Here we report distinct gating charge movement of Kv2.1/Kv6.4 heterotetrameric channels, compared to Kv2.1 homotetramers, as revealed by gating current recordings from mammalian cells expressing these channels. The gating charge movement of Kv2.1/Kv6.4 heterotetrameric channels displayed an extra component around the physiological K(+ equilibrium potential, characterized by a second sigmoidal relationship of the voltage-dependence of gating charge movement. This distinct gating charge displacement reflects movement of the Kv6.4 voltage-sensing domain and has a voltage-dependency that matches the hyperpolarizing shift in Kv2.1/Kv6.4 channel inactivation. These results provide a mechanistic basis for the modulation of Kv2.1 channel inactivation gating kinetics by silent Kv6.4 subunits.

Genetically modified crops that express insecticidal Bacillus thuringiensis (Bt) proteins have become a primary approach for control of lepidopteran (moth) and coleopteran (beetle) pests that feed by chewing the plants. However, the sap-sucking insects (Hemiptera) are not particularly susceptible to Bt toxins. In this study, we describe two Cry toxins (Cry64Ba and Cry64Ca) from Bt strain 1012 that showed toxicity against two important hemipteran rice pests, Laodelphax striatellus and Sogatella furcifera Both of these proteins contain an ETX/MTX2 domain and share common sequence features with the β-pore-forming toxins. Coexpression of cry64Ba and cry64Ca genes in the acrystalliferous Bt strain HD73 - resulted in high insecticidal activity against both hemipteran pests. No toxicity was observed on other pests such as Ostrinia furnacalis , Plutella xylostella , or Colaphellus bowringi Also, no hemolytic activity or toxicity against cancer cells was detected. Binding assays showed specific binding of the Cry64Ba/Cry64Ca toxin complex to brush border membrane vesicles isolated from L. striatellus Cry64Ba and Cry64Ca are Bt Cry toxins highly effective against hemipteran pests and could provide a novel strategy for the environmentally friendly biological control of rice planthoppers in transgenic plants. IMPORTANCE In Asia, rice is an important staple food, whose production is threatened by rice planthoppers. To date, no effective Bacillus thuringiensis (Bt) protein has been shown to have activity against rice planthoppers. We cloned two Bt toxin genes from Bt strain 1012 that showed toxicity against small brown planthoppers ( Laodelphax striatellus ) and white-backed planthoppers ( Sogatella furcifera ). To our knowledge, the proteins encoded by the cry64Ba and cry64Ca genes are the most efficient insecticidal Bt Cry proteins with activity against hemipteran insects reported so far. Cry64Ba and Cry64Ca showed no toxicity against some lepidopteran or coleopteran pests

As a preliminary study for production technology of 64 Cu based on nuclear reaction of 64 Ni (p,n) 64 Cu, the nickel targets were prepared by electroplating method using acidic solution of nickel chloride - boric acid and basic solution of nickel sulphate - nickel chloride mixtures on a silver-surfaced target holder. The simulated solution of Ni(II) - Cu(II) matrix was considered as the solution of post-proton-irradiated nickel containing radioactive copper. In the presented work the irradiation of nickel target was omitted, while the radioactive copper was obtained from neutron irradiation of CuO target. The separation of radioactive copper was based on anion exchange column chromatography in which the radiocopper was conditioned to form CuCl 4 2- anion complex, while the nickel was kept as Ni 2+ cation. It was found that the electroplating deposit from the acidic solution was better than that form the basic solution. By conditioning the matrix solution in 6 M HCl, the radioactive copper was indicated in the forms of Cu 2+ and CuCl 4 2- while the nickel was in the form of Ni 2+ . In the condition of 9 M HCl, the radioactive copper was in the form of CuCl 4 2- , while the nickel was found as both Ni 2+ and CuCl 4 2- . The best condition of separation was in 8 M HCl in which the radioactive copper was in the form of CuCl 4 2- , while the nickel was in the form of Ni 2+ . The retained CuCl 4 2- was then changed back into Cu 2+ cation and eluted out from the column by using 0.05 M HCl. The γ-spectrometric analysis showed a single strong peak at 511 keV in accordance to γ-annihilation peak coming from positron decay of 64 Cu, and a very weak peak at 1346 keV related to γ-ray from internal energy transition of 64 Cu.

A high performance 32 X 32 peak detector array is introduced. This detector consists of a 32 X 32 array of thresholding photo-transistor cells, manufactured with a standard MOSIS digital 2-micron CMOS process. A built-in thresholding function that is able to perform 1024 thresholding operations in parallel strongly distinguishes this chip from available CCD detectors. This high speed detector offers responses from one to 10 milliseconds that is much higher than the commercially available CCD detectors operating at a TV frame rate. The parallel multiple peaks thresholding detection capability makes it particularly suitable for optical correlator and optoelectronically implemented neural networks. The principle of operation, circuit design and the performance characteristics are described. Experimental demonstration of correlation peak detection is also provided. Recently, we have also designed and built an advanced version of a 64 X 64 thresholding photodetector array chip. Experimental investigation of using this chip for pattern recognition is ongoing.

Purpose MA.17R was a Canadian Cancer Trials Group-led phase III randomized controlled trial comparing letrozole to placebo after 5 years of aromatase inhibitor as adjuvant therapy for hormone receptor-positive breast cancer. Quality of life (QOL) was a secondary outcome measure of the study, and here, we report the results of these analyses. Methods QOL was measured using the Short Form-36 (SF-36; two summary scores and eight domains) and menopause-specific QOL (MENQOL; four symptom domains) at baseline and every 12 months up to 60 months. QOL assessment was mandatory for Canadian Cancer Trials Group centers but optional for centers in other groups. Mean change scores from baseline were calculated. Results One thousand nine hundred eighteen women were randomly assigned, and 1,428 women completed the baseline QOL assessment. Compliance with QOL measures was > 85%. Baseline summary scores for the SF-36 physical component summary (47.5 for letrozole and 47.9 for placebo) and mental component summary (55.5 for letrozole and 54.8 for placebo) were close to the population norms of 50. No differences were seen between groups in mean change scores for the SF-36 physical and mental component summaries and the other eight QOL domains except for the role-physical subscale. No difference was found in any of the four domains of the MENQOL Conclusion No clinically significant differences were seen in overall QOL measured by the SF-36 summary measures and MENQOL between the letrozole and placebo groups. The data indicate that continuation of aromatase inhibitor therapy after 5 years of prior treatment in the trial population was not associated with a deterioration of overall QOL.

ERC-55, encoded from RCN2, is localized in the ER and belongs to the CREC protein family. ERC-55 is involved in various diseases and abnormal cell behavior, however, the function is not well defined and it has controversially been reported to interact with a cytosolic protein, the vitamin D receptor. We have used a number of proteomic techniques to further our functional understanding of ERC-55. By affinity purification, we observed interaction with a large variety of proteins, including those secreted and localized outside of the secretory pathway, in the cytosol and also in various organelles. We confirm the existence of several ERC-55 splicing variants including ERC-55-C localized in the cytosol in association with the cytoskeleton. Localization was verified by immunoelectron microscopy and sub-cellular fractionation. Interaction of lactoferrin, S100P, calcyclin (S100A6), peroxiredoxin-6, kininogen and lysozyme with ERC-55 was further studied in vitro by SPR experiments. Interaction of S100P requires [Ca(2+)] of approximately 10(-7) M or greater, while calcyclin interaction requires [Ca(2+)] of >10(-5) M. Interaction with peroxiredoxin-6 is independent of Ca(2+). Co-localization of lactoferrin, S100P and calcyclin with ERC-55 in the perinuclear area was analyzed by fluorescence confocal microscopy. The functional variety of the interacting proteins indicates a broad spectrum of ERC-55 activities such as immunity, redox homeostasis, cell cycle regulation and coagulation.

Introduction To determine the prevalence of sexual dysfunction in pre and postmenopausal women. Material and methods A cross-sectional, descriptive, comparative study was done in climacteric women from 40 to 59 years of age. Female sexual function was evaluated with the female sexual function index (FSFI) on the day of consultation. The comparison between pre and postmenopausal women and between those with or without sexual dysfunction was done with Mann Whitney U test, χ2, and Spearman’s correlation analysis was done. Results One hundred and ten women were studied, 55 were premenopausal (group 1) and 55 postmenopausal (group 2). The median of age in group 1 was 46 (40-58) years and in group 2 it was 53 (45-60) years. Premenopausal women had higher education level than postmenopausal women (p < 0.023). From those sexually active, 62.1% had sexual dysfunction. No statistically significant difference was found in education level, religion and marital status between women with or without sexual dysfunction. No difference in sexual dysfunction was found between premenopausal (62.1%) and postmenopausal (62.5%) women, but greater sexual dysfunction was found starting from 50 years age. Age negatively correlated with FSFI score (ρ = –0.324, p < 0.001). Conclusion In postmenopausal women, those older had a greater impairment in sexual function.

Objective: To study the correlation of low-dose 64-row multi-detector computed tomography (MDCT) with echocardiography and cardiac catheterization angiography (CCA) in the assessment of pulmonary arterial anatomy in children with cyanotic congenital heart disease (CCHD). Materials and methods: This prospective study included 105 children (74 males, 31 females) with CCHD, in the age group of 2 months to 20 years, who underwent 64-row MDCT examination (low-dose CT protocol), echocardiography and CCA for the assessment of pulmonary arteries, including visualization, presence of confluence, stenosis and collaterals. Statistical analysis was performed using the non-parametric statistical analysis test to evaluate the concordance or discordance between echocardiography, MDCT and CCA. Results: 64-row MDCT detected significantly more main and branch pulmonary arteries, patent pulmonary confluences, and more cases of pulmonary artery stenosis. CCA detected more major aorto-pulmonary collaterals than MDCT, whereas echocardiography failed to identify these major aorto-pulmonary collaterals. The effective CT radiation dose to patients less than 2 years of age was in the range of 0.7–2.5 mSv, where as the dose in patients more than 2 years of age ranged from that of 2.1 to 4.2 mSv, which is much less than the radiation dose reported in cardiac catheterization angiography. Conclusion: In cases where cardiac MRI cannot be performed, or is not sufficiently informative, low-dose 64-row MDCT correlates well with CCA and can provide adequate information about pulmonary arterial anatomy in children with cyanotic congenital heart disease, and can replace invasive cardiac catheterization angiography with markedly reduced radiation dosage to the patient.

Full Text Available Introduction: Humanism is cultivated through reflection and self-awareness. We aimed to employ fourth-year medical students, recognized for their humanism, to facilitate reflective sessions for second-year medical students with the intention of positively influencing reflective process toward humanistic development. Methods/Analysis: A total of 186 students were randomly assigned to one of three comparison arms: eight groups of eight students (64 students were facilitated by a fourth-year student who was a Gold Humanism Honor Society member (GHHS; eight groups (64 students by a volunteer non-GHHS student; and seven groups (58 students were non-facilitated. Before sessions, second-year students set learning goals concerning interactions with patients; fourth-year students received training materials on facilitation. Groups met twice during their 10 clinical site visits. At the last session, students completed a reflective assignment on their goal progress. Comparative mixed method analyses were conducted among the three comparison arms on reflection (reflective score on in-session assignment and session satisfaction (survey in addition to a thematic analysis of responses on the in-session assignment. Results: We found significant differences among all three comparison arms on students’ reflective scores (p=0.0003 and satisfaction (p=0.0001. T-tests comparing GHHS- and non-GHHS-facilitated groups showed significantly higher mean reflective scores for GHHS-facilitated groups (p=0.033; there were no differences on session satisfaction. Thematic analysis of students’ reflections showed attempts at self-examination, but lacked depth in addressing emotions. There was a common focus on achieving comfort and confidence in clinical skills performance. Discussion/Conclusions: Near peers, recognized for their humanism, demonstrated significant influence in deepening medical students’ reflections surrounding patient interactions or humanistic

Objective: To assess the feasibility of using an automatic tube current modulation (ATCM) method to obtain consistent image quality with reduced radiation dose for young children undergoing chest scans with a set of 64-slice spiral CT. Methods: Fifty young children underwent chest scans on a GE 64-slice VCT with automatic tube current modulation. The noise index (NI) for this study group was set to 8 or 9 based on the proposed reference for pediatric chest imaging in our hospital. We compared image quality and radiation dose for the study group with the age-matched control group of 50 young children acquired with standard protocol of fixed-mAs (120 and 150 mAs for under 1 and above 1 year old, respectively). The volume CT dose index(CTDIvol) values were recorded for both groups. Two experienced pediatric radiologists assessed image quality on a 5-point scale with 5 being the best. Scores greater than or equal to 3 were considered clinically acceptable. The degree of interobserver concordance was determined by Kappa statistics. Results: The average objective image noise and CTDIvol for control group was (4.78±0.58) and (6.68±0.62) mGy, respectively. For the study group the mean value of objective mAs was (41.6±11.6) (20-79 mAs) with mean CTDIvol of (2.34±0.71) mGy, and the use of ATCM produced mean noise of (7.84±0.66). The average CTDIvol with the use of NI of 8-9 was about 65% lower than that with the fixed mAs setting. The mean image quality score for the study group and control group was (3.46±0.40) and (4.65±0.46) respectively. All studies had acceptable image quality, and there was good inter-observer agreement in diagnostic acceptability (Kappa=0.474 and 0.536). Conclusion: The automatic tube current modulation method could be used to obtain consistent image quality for young children undergoing 64-slice MSCT chest scans. With proper noise level setting (NI=8 or 9), one may obtain clinically acceptable images with much reduced radiation dose. (authors)

Full Text Available Abstract Background Indigenous Australians are known to be at greater risk of morbidity and mortality from mental health related conditions, but most available data relate to the use of mental health services, and little is known about other aspects of social and emotional wellbeing. Using the first available nationally representative data, we examined the prevalence and patterning of psychological distress among Indigenous Australian adults and compared these with corresponding data from the non-Indigenous population. Methods The analysis used weighted data on psychological distress, as measured by a modified Kessler Psychological Distress score (K5, and a range of socio-demographic measures for 5,417 Indigenous and 15,432 non-Indigenous adults aged 18-64 years from two nationally representative surveys. Very high psychological distress (VHPD was defined as a K5 score ≥ 15 (possible range = 5-25. Results Indigenous adults were about three times more likely than non-Indigenous adults to be classified with VHPD: 14.5% (95% confidence interval (CI 12.9-16.0% versus 5.5% (95% CI 5.0-5.9%. After adjusting for age, most socio-demographic variables were significantly associated with VHPD in both populations, although the relative odds were generally larger among non-Indigenous people. Indigenous people in remote areas had a lower prevalence of VHPD than their non-remote counterparts, and only marital status, main language, and food insecurity were significantly associated with VHPD in remote areas. Conclusions Higher absolute levels of VHPD combined with smaller socio-demographic gradients in the Indigenous population suggest the importance of risk factors such as interpersonal racism, marginalization and dispossession, chronic stress and exposure to violence that are experienced by Indigenous Australians with common and/or cross-cutting effects across the socioeconomic spectrum. The lower prevalence of VHPD and lack of association with many socio

The present study was carried out among school children of Kathmandu valley to determine the prevalence of dental caries in two age groups. Methods: The study was conducted from December 2007 to May 2008. The age of the school children of the study was divided into two group: 5 - 6 years and 12 - 13 years. A stratifi ed cluster sampling with proportional allocation was used while grouping the subjects. The dental status examination was done with the help of trained dentists. Decayed, missed and fi lled teeth index and decayed, missed and fi lled surfaces index (dmft for primary dentition and DMFT for permanent dentition were used as the standard tools for the determination of prevalence. Results: A total of 638 students (325 of age group 12 - 13 years and 313 of age group 5 - 6 years from 30 different schools of the Kathmandu valley were included in the study. The caries status was found higher in the age group of 5 - 6 years than in the 12 - 13 years and it was found to be statistically signifi cant (p < 0.001. The dmfs and caries percentage of the age group 5 - 6 years and the DMFS and caries percent of the 12 - 13 years was found to be 3.79, 69 % and 1.6, 53.23 % respectively. The dmft/dmfs value was found to be signifi cant according to the districts in the 5 - 6 years age group whereas the DMFS was found statistically signifi cant among the sexes of the 12 - 13 years age group. Conclusions: The caries percentage was found to be above the recommended level of the World Health Organization. However, the DMFS and DMFT values were within the WHO level.

Purpose: The optimal management of breast cancer in elderly women is not well established. Therefore, the present study was undertaken to evaluate the outcome of breast cancer in elderly women treated with breast-conserving surgery and definitive breast irradiation. Methods and Materials: An analysis was performed of 558 women age ≥ 50 years treated with breast-conserving surgery and definitive breast irradiation for Stages I-II invasive carcinoma of the breast. Of the 558 total women, there were 173 elderly women age ≥ 65 years and a comparison group of 385 women age 50-64 years. Treatment for all women included complete gross excision of the primary tumor, pathologic axillary lymph node staging, and definitive breast irradiation. Adjuvant systemic chemotherapy was used in 18% (102 out of 558) of the overall group. Adjuvant tamoxifen was used in 17% (94 out of 558) of the overall group. The median follow-up after treatment was 6.2 years (mean = 6.4 years; range 0.1-15.4 years). Results: Elderly patients age ≥ 65 years and patients age 50-64 years were both found to have tumors with adverse prognostic features, including clinical T2 lesions (43 vs. 34%, respectively; p = 0.055), estrogen receptor negativity (9 vs. 16%, respectively; p = 0.13), and progesterone receptor negativity (17 vs. 21%, respectively; p = 0.50). Pathologic axillary lymph node staging showed that 24% of the elderly women were node positive, including 8% with four or more positive nodes, which was not different from women age 50-64 years (p = 0.23). There was no difference between the two age groups for the rate of deaths from breast cancer at 10 years (13 vs. 13%, respectively; p = 0.71). However, there was a significant difference between the two age groups for the rate of deaths from intercurrent disease at 10 years (11 vs. 2%, respectively; p = 0.0006). There were no differences between the two age groups for the 10-year rates of overall survival (77 vs. 85%, respectively; p = 0

Varenicline is approved as an aid to smoking cessation in adults aged > or =18 years. The goal of this study was to characterize the multiple-dose pharmacokinetics, safety, and tolerability of varenicline in adolescent smokers. This multicenter, randomized, double-blind, placebo-controlled, parallel-group study enrolled healthy 12- to 16-year-old smokers (> or =3 cigarettes daily) into high-body-weight (>55 kg) and low-body-weight (daily. The apparent renal clearance (CL/F) and volume of distribution (V/F) of varenicline and the effect of body weight on these parameters were estimated using nonlinear mixed-effects modeling. The high-body-weight group consisted of 35 subjects (65.7% male; 77.1% white; mean age, 15.2 years). The low-body-weight group consisted of 37 subjects (37.8% male; 48.6% white; mean age, 14.3 years). The pharmacokinetic parameters of varenicline were dose proportional over the dose range from 0.5 to 2 mg/d. The CL/F for a 70-kg adolescent was 10.4 L/h, comparable to that in a 70-kg adult. The estimated varenicline V/F was decreased in individuals of small body size, thus predicting a varenicline C(max) approximately 30% greater in low-body-weight subjects than in high-body-weight subjects. In high-body-weight subjects, steady-state varenicline exposure, as represented by the AUC(0-24), was 197.0 ng . h/mL for varenicline 1 mg BID and 95.7 ng . h/mL for varenicline 0.5 mg BID, consistent with values reported previously in adult smokers at the equivalent doses. In low-body-weight subjects, varenicline exposure was 126.3 ng . h/mL for varenicline 0.5 mg BID and 60.1 ng . h/mL for varenicline 0.5 mg once daily, values at the lower end of the range observed previously in adults at doses of 1 mg BID and 0.5 mg BID, respectively. Among high-body-weight subjects, adverse events (AEs) were reported by 57.1% of subjects in both the high- and low-dose varenicline groups and by 14.3% of subjects in the placebo group; among low-body-weight subjects, AEs

Workers approaching retirement may be particularly vulnerable to economic downturns. This study assesses whether exposure to economic downturns around retirement age leads to poorer cognitive function in later life. Longitudinal data for 13,577 individuals in the Health and Retirement Study were linked to unemployment rates in state of residence. Random- and fixed-effect models were used to examine whether downturns at 55-64 years of age were associated with cognitive functioning levels and decline at ≥65 years, measured by the Wechsler Adult Intelligence Scale-Revised. Longer exposure to downturns at 55-64 years of age was associated with lower levels of cognitive function at ≥65 years. Compared to individuals experiencing only up to 1 year in a downturn at 55-64 years of age, individuals experiencing two downturns at these ages had 0.09 point (95% Confidence Interval [CI, -0.17, -0.02]) lower cognitive functioning scores at ≥65 years (3 years: b = -0.17, 95%CI [-0.29, -0.06]; 4 years: b = -0.14, 95%CI [-0.25, -0.02]; ≥5 years: b = -0.22, 95%CI [-0.38, -0.06]). Downturns at 55-64 years of age were not associated with rates of cognitive decline. Exposure to downturns around retirement is associated with a long-lasting decline in cognitive function in later life. Policies mitigating the impact of downturns on older workers may help to maintain cognitive function in later life.

Purpose: To compare the contribution of 64 channel multidetector row computed tomography angiography (64MDCT-angiography) with digital subtraction angiography (DSA) in the detection of intracranial aneurysms. Methods and materials: Twenty-nine patients (10 males and 19 females, age: 40-84 years; average: 61.9 years) with clinical and imaging findings strongly suggesting the presence of subaracnoid hemorrhage underwent 64MDCT-angiography and DSA with a short interval between the two examinations (less than 12 h-5 days). CT parameters were: 64 mm x 0.5 mm collimation, pitch-0.828 and helical pitch-53. DSA were performed with standard technique (four vessel catheterization) and multiple projections. Axial CT scans as well as maximum intensity projection, volume rendering and multiplanar reformations and angiographic views were independently reviewed by four readers (two for 64MDCT-angiography and two for DSA). Consensus was reached for discordant cases. DSA was considered as the standard of reference. Results: In 29 patients, 28 aneurysms were found (14 patients had 1 aneurysm, 4 patients had 2 aneurysms and 2 patients had 3 aneurysms; in 9 patients no aneurysm were found). 64MDCT-angiography detected 26/28 aneurysms. No false-positive sites were recognized. The sensitivity, specificity, positive and negative predictive values and diagnostic accuracy were, respectively, 92.8, 100, 100, 99.4 and 99.5%. Conclusions: 64MDCT-angiography is helpful in detecting intracranial aneurysms with results similar to those of DSA but with less discomfort and risks for the patients and can be considered for the first line imaging technique. Conventional angiography is still needed in doubtful cases or negative MDCT-angiography associated with a strong clinical suspect

Sixty-two patients with primary carcinoma of the female urethra were treated with a combined radiation therapy (high-dose intracavitary vaginal radium and external beam). Treatment was strictly individualized, but an administered tumor dose of 5500-7000 rad (55-70 Gy) was always attempted. Forty-two patients (67.7%) had tumors of the anterior urethra, and in 20 women (32.3%) the posterior urethra was involved. In 19 patients (30.6%) the clinical diagnosis of lymph node involvement was made. The overall 5-year-survival rate was 64.5%. Patients with anterior urethral carcinoma had a higher 5-year-survival rate (71.4%) than patients with posterior carcinoma (50.0%). The favorable results underline the substantial role of radiation therapy for this malignancy.

OBJECTIVE Recommendations for the surgical treatment of isolated lumbar spinal stenosis (LSS) (i.e., in the absence of concomitant scoliosis or spondylolisthesis) are unclear. The aims of this study were to investigate trends in the surgical treatment of isolated LSS in US adults and determine implications for outcomes. METHODS The authors analyzed inpatient and outpatient claims from the Truven Health Analytics MarketScan Commercial Claims and Encounters Database for 20,279 patients aged 40-64 years who underwent surgery for LSS between 2010 and 2014. Only patients with continuous 12-month insurance coverage after surgery were included. The rates of decompression with arthrodesis versus decompression only and of simple (1- or 2-level, single-approach) versus complex (> 2-level or combined-approach) arthrodesis were analyzed by year and geographic region. These trends were further analyzed with respect to complications, length of hospital stay, payments made to the hospital, and patient discharge status. Statistical significance was set at p < 0.05. RESULTS The proportion of patients who underwent decompression with arthrodesis compared with decompression only increased significantly and linearly from 2010 to 2014 (OR 1.08; 95% CI 1.06-1.10). Arthrodesis was more likely to be complex rather than simple with each subsequent year (OR 1.4; 95% CI 1.33-1.49). This trend was accompanied by an increased likelihood of postoperative complications (OR 1.11; 95% CI 1.02-1.21), higher costs (payments increased by a mean of US$1633 per year; 95% CI 1327-1939), and greater likelihood of being discharged to a skilled nursing facility as opposed to home (OR 1.11; 95% CI 1.03-1.20). The South and Midwest regions of the US had the highest proportions of patients undergoing arthrodesis (48% and 42%, respectively). The mean length of hospital stay did not change significantly (p = 0.324). CONCLUSIONS From 2010 to 2014, the proportion of adults undergoing decompression with

Objective: To determine the optimal contrast injection protocol for 64-MDCT coronary angiography. Materials and methods: One hundred and fifty consecutive patients scheduled to undergo retrospectively electrocardiographically gated 64-MDCT. Each 30 patients were assigned to use a different contrast protocol: group 1: uniphasic protocol (contrast injection without saline flush); group 2: biphasic protocol (contrast injection with saline flush); group 3A, 3B and 3C: triphasic protocol (contrast media + different saline diluted contrast media + saline flush). Image quality scores and artifacts were compared and evaluated on both transaxial and three-dimensional coronary artery images among each contrast protocol. Results: Among the triphasic protocol groups, group 3A (30%:70% contrast media-saline mixture was used in second phase) used the least contrast media and had the least frequency of streak artifacts, but there were no significant differences in coronary artery attenuation, image quality, visualization right and left heart structures. Among the uniphasic protocol group (group 1), biphasic protocol group (group 2) and triphasic protocol subgroup (group 3A), there were no significant differences in image quality scores of coronary artery (P = 0.18); uniphasic protocol group had the highest frequency of streak artifacts (20 cases) (P < 0.05) and had the most amount contrast media (67.0 ± 5.3 ml); biphasic protocol group had the least amount of contrast media (59.9 ± 4.9 ml) (P < 0.05) and had the highest attenuation of left main coronary artery and right coronary artery (P < 0.01), but had the least amount of clear visualization right heart structure (6 cases); triphasic protocol group (group 3A) had the most amount of clear visualization right heart structures (29 cases) were the most among the three groups (P < 0.05). Conclusion: Biphasic protocol are superior to the traditional uniphasic protocols for using the least total contrast media, having the least

Full Text Available Significant upregulation of the integrin αvβ6 has been described as a prognostic indicator in several cancers, making it an attractive target for tumor imaging. This study compares variants of a PEGylated αvβ6-targeting peptide, bearing either an [>18F]fluorobenzoyl prosthetic group ([18F]FBA-PEG-A20FMDV2 or different [64Cu]copper chelators (DOTA-PEG-A20FMDV2, CB-TE2A-PEG-A20FMDV2. The compounds were evaluated in vitro by enzyme-linked immunosorbent assay (against the integrin αvβ6 and the closely related integrin αvβ6 and by cell labeling (αvβ6-positive DX3puroβ6/αvβ6-negative DX3puro and in vivo using micro-positron emission tomography in a mouse model bearing paired DX3puroβ6/Dx3puro xenografts. In vitro, all three compounds showed excellent αvβ6-specific binding (50% inhibitory concentration [IC50](αvβ6 = 3 to g nmol/L; IC50(αvβ3 > 10 (μmol/L. In vivo, they displayed comparable, preferential uptake for the αvβ6-expressmg xenograft over the αvβ6-negative control (> 4:1 ratio at 4 hours postinjection. Whereas [64Cu]Cu-DOTA-PEG-A20FMDV2 resulted in increased levels of radioactivity in the liver, [64Cu]Cu-CB-TE2A-PEG-A20FMDV2 did not. Significantly, both 64Cu-labeled tracers showed unexpectedly high and persistent levels of radioactivity in the kidneys (> 40% injected dose/g at 4 and 12 hours postinjection. The findings underscore the potential influence of the prosthetic group on targeted in vivo imaging of clinically relevant markers such as αvβ6. Despite identical targeting peptide moiety and largely equal in vitro behavior, both 64Cu-labeled tracers displayed inferior pharmacokinetics, making them in their present form less suitable candidates than the 18F-labeled tracer for in vivo imaging of αvβ6

Activity report of the Neutrino Research Group. Year 2006

International Nuclear Information System (INIS)

2007-01-01

For the last two decades, neutrino physics has been producing major discoveries including neutrino oscillations. These results gave clear confirmation that active neutrinos oscillate and therefore have mass with three different mass states. This is a very important result showing that the Minimal Standard Model is incomplete and requires an extension which is not yet known. The neutrino research field is very broad and active, at the frontier of today's particle physics. The Neutrino Research Group (GDR) was created in January 2005 with the aim of gathering CEA and CNRS research teams working on Neutrino Physics on experimental or theoretical level. This document is the 2006 activity report of the research group, two years after its creation. It presents the results of the 5 working groups: 1 - Determination of neutrino parameters; 2 - Physics beyond the standard model; 3 - Neutrinos in the universe; 4 - Accelerators, detection means, R and D and valorisation; 5 - Common tools to all working groups. The proposed neutrino physics road-map and the actual and future short-, medium- and long-term projects are presented in appendixes. The Neutrino research group organization, the Memphys specific mission group, the research group participating laboratories and teams, as well as the Memphys project are presented too

Purpose MA.17R was a Canadian Cancer Trials Group–led phase III randomized controlled trial comparing letrozole to placebo after 5 years of aromatase inhibitor as adjuvant therapy for hormone receptor–positive breast cancer. Quality of life (QOL) was a secondary outcome measure of the study, and here, we report the results of these analyses. Methods QOL was measured using the Short Form-36 (SF-36; two summary scores and eight domains) and menopause-specific QOL (MENQOL; four symptom domains) at baseline and every 12 months up to 60 months. QOL assessment was mandatory for Canadian Cancer Trials Group centers but optional for centers in other groups. Mean change scores from baseline were calculated. Results One thousand nine hundred eighteen women were randomly assigned, and 1,428 women completed the baseline QOL assessment. Compliance with QOL measures was > 85%. Baseline summary scores for the SF-36 physical component summary (47.5 for letrozole and 47.9 for placebo) and mental component summary (55.5 for letrozole and 54.8 for placebo) were close to the population norms of 50. No differences were seen between groups in mean change scores for the SF-36 physical and mental component summaries and the other eight QOL domains except for the role-physical subscale. No difference was found in any of the four domains of the MENQOL Conclusion No clinically significant differences were seen in overall QOL measured by the SF-36 summary measures and MENQOL between the letrozole and placebo groups. The data indicate that continuation of aromatase inhibitor therapy after 5 years of prior treatment in the trial population was not associated with a deterioration of overall QOL. PMID:29328860

Type 2 diabetes can often be prevented by lifestyle modification; however, successful lifestyle intervention programmes are labour intensive. Mobile phone messaging is an inexpensive alternative way to deliver educational and motivational advice about lifestyle modification. We aimed to assess whether mobile phone messaging that encouraged lifestyle change could reduce incident type 2 diabetes in Indian Asian men with impaired glucose tolerance. We did a prospective, parallel-group, randomised controlled trial between Aug 10, 2009, and Nov 30, 2012, at ten sites in southeast India. Working Indian men (aged 35-55 years) with impaired glucose tolerance were randomly assigned (1:1) with a computer-generated randomisation sequence to a mobile phone messaging intervention or standard care (control group). Participants in the intervention group received frequent mobile phone messages compared with controls who received standard lifestyle modification advice at baseline only. Field staff and participants were, by necessity, not masked to study group assignment, but allocation was concealed from laboratory personnel as well as principal and co-investigators. The primary outcome was incidence of type 2 diabetes, analysed by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00819455. We assessed 8741 participants for eligibility. 537 patients were randomly assigned to either the mobile phone messaging intervention (n=271) or standard care (n=266). The cumulative incidence of type 2 diabetes was lower in those who received mobile phone messages than in controls: 50 (18%) participants in the intervention group developed type 2 diabetes compared with 73 (27%) in the control group (hazard ratio 0·64, 95% CI 0·45-0·92; p=0·015). The number needed to treat to prevent one case of type 2 diabetes was 11 (95% CI 6-55). One patient in the control group died suddenly at the end of the first year. We recorded no other serious adverse events. Mobile

This study aimed to elucidate the relationships between erectile dysfunction (ED) and depression or anxiety. Subjects were 1,419 Japanese men aged 40-64 years. ED was assessed by the International Index of Erectile Function 5 (IIEF-5) score (Japanese version), and depression and anxiety symptoms were assessed by the Hospital Anxiety and Depression Scale (HADS). In this study ED cases were defined as those whose IIEF-5 value was less than 12, and a score of 8 or higher was used to classify a subject as suffering from depression or anxiety, respectively. The prevalence odds ratio (OR) of ED was calculated with confidence interval (CI) estimated by the Woolf's method by five age groups (40-44, 45-49, 50-54, 55-59, 60-64 years). To control for age, body mass index, smoking, and alcohol drinking factors, we conducted the multivariate logistic regression analysis for calculating adjusted ORs and 99% CIs. ED was significantly associated with depression in age groups 45-49 (OR 3.42, 99% CI 1.51-7.76) and 50-54 years (OR 2.43, 99% CI 1.11-5.35). After using multivariate analysis, adjusted OR also showed statistical significance. (OR 2.02, 99% CI 1.32-3.08). ED was significantly associated with anxiety in the 50-55-year-old age group (OR 2.48, 99% CI 1.12-5.47). After using multivariate analysis, adjusted OR also showed statistical significance (OR 1.77, 99% CI 1.15-2.72). The concomitant depression and anxiety group (A+D+) had significantly higher prevalence of ED than the control group (A-D-) in both the 45-49 and 50-54 age groups. (P < 0.01) ED associated significantly with depression and anxiety status only in late 40s to early 50s (45-55 years) in male Japanese. Furthermore, comorbidities of depression and anxiety strengthen this association. Our results might be useful in furthering understanding of ED etiology and determining a target population for prevention in ED subjects.

Installation of MCNP on 64-bit parallel computers

1995-01-01

The Monte Carlo radiation transport code MCNP has been successfully ported to two 64-bit workstations, the SGI and DEC Alpha. We found the biggest problem for installation on these machines to be Fortran and C mismatches in argument passing. Correction of these mismatches enabled, for the first time, dynamic memory allocation on 64-bit workstations. Although the 64-bit hardware is faster because 8-bytes are processed at a time rather than 4-bytes, we found no speed advantage in true 64-bit coding versus implicit double precision when porting an existing code to the 64-bit workstation architecture. We did find that PVM multiasking is very successful and represents a significant performance enhancement for scientific workstations

Separation of copper-64 from copper phthalocyanine

International Nuclear Information System (INIS)

Battaglin, R.I.M.

1979-01-01

The separation of copper-64 from irradiated copper phthalocyanine by Szilard-Chalmers effect is studied. Two methods of separation are used: one of them is based on the dissolution of the irradiated dry compound in concentrated sulfuric acid following its precipitation in water. In the other one the compound is irradiated with water in paste form following treatment with water and hydrochloric acid. The influence of the crystal form of the copper phthalocyanine on the separation yield of copper-64 is shown. Preliminary tests using the ionic exchange technique for purification and changing of copper-64 sulfate to chloride form are carried out. The specific activity using the spectrophotometric technique, after the determination of the copper concentration in solution of copper-64, is calculated. (Author) [pt

Liposomes are nanoparticles used in drug delivery that distribute over several days in humans and larger animals. Radiolabeling with long-lived positron emission tomography (PET) radionuclides, such as manganese-52 ( 52 Mn, T½=5.6days), allow the imaging of this biodistribution. We report optimized protocols for radiolabeling liposomes with 52 Mn, through both remote-loading and surface labeling. For comparison, liposomes were also remote-loaded and surface labeled with copper-64 ( 64 Cu, T½=12.7h) through conventional means. The chelator DOTA was used in all cases. The in vivo stability of radiometal chelates is widely debated but studies that mimic a realistic in vivo setting are lacking. Therefore, we employed these four radiolabeled liposome types as platforms to demonstrate a new concept for such in vivo evaluation, here of the chelates 52 Mn-DOTA and 64 Cu-DOTA. This was done by comparing "shielded" remote-loaded with "exposed" surface labeled variants in a CT26 tumor-bearing mouse model. Remote loading (90min at 55°C) and surface labeling (55°C for 2h) of 52 Mn gave excellent radiolabeling efficiencies of 97-100% and 98-100% respectively, and the liposome biodistribution was imaged by PET for up to 8days. Liposomes with surface-conjugated 52 Mn-DOTA exhibited a significantly shorter plasma half-life (T ½ =14.4h) when compared to the remote-loaded counterpart (T ½ =21.3h), whereas surface-conjugated 64 Cu-DOTA cleared only slightly faster and non-significantly, when compared to remote-loaded (17.2±2.9h versus 20.3±1.2h). From our data, we conclude the successful remote-loading of liposomes with 52 Mn, and furthermore that 52 Mn-DOTA may be unstable in vivo whereas 64 Cu-DOTA appears suitable for quantitative imaging.

Copper-64 is an attractive radionuclide for PET imaging and is frequently used in clinical applications. The aim of this study was to perform a side-by-side comparison of the in vitro and in vivo performance of 64Cu-NODAGA-JR11 (NODAGA = 1,4,7-triazacyclononane,1-glutaric acid,4,7-acetic acid, JR11 = p-Cl-Phe-cyclo(D-Cys-Aph(Hor)-D-Aph(cbm)-Lys-Thr-Cys)D-Tyr-NH2), a somatostatin receptor 2 antagonist, with the clinically used sst2 agonist 64Cu-DOTA-TATE ((TATE = D-Phe-cyclo(Cys-Tyr-D-Trp-Lys-Thr-Cys)Thr). In vitro studies demonstrated Kd values of 5.7±0.95 nM (Bmax = 4.1±0.18 nM) for the antagonist 64/natCu-NODAGA-JR11 and 20.1±4.4. nM (Bmax = 0.48±0.18 nM) for the agonist 64/natCu-DOTA-TATE. Cell uptake studies showed the expected differences between agonists and antagonists. Whereas 64Cu-DOTA-TATE (the agonist) showed very effective internalization in the cell culture assay (with 50% internalized at 4 hours post-peptide addition under the given experimental conditions), 64Cu-NODAGA-JR11 (the antagonist) showed little internalization but strong receptor-mediated uptake at the cell membrane. Biodistribution studies of 64Cu-NODAGA-JR11 showed rapid blood clearance and tumor uptake with increasing tumor-to-relevant organ ratios within the first 4 hours and in some cases, 24 hours, respectively. The tumor washout was slow or non-existent in the first 4 hours, whereas the kidney washout was very efficient, leading to high and increasing tumor-to-kidney ratios over time. Specificity of tumor uptake was proven by co-injection of high excess of non-radiolabeled peptide, which led to >80% tumor blocking. 64Cu-DOTA-TATE showed less favorable pharmacokinetics, with the exception of lower kidney uptake. Blood clearance was distinctly slower and persistent higher blood values were found at 24 hours. Uptake in the liver and lung was relatively high and also persistent. The tumor uptake was specific and similar to that of 64Cu-NODAGA-JR11 at 1 h, but release from the tumor

Forced differentiation of CFU-S by iron-55 erythrocytocide

International Nuclear Information System (INIS)

Reincke, U.; Brookoff, D.; Burlington, H.; Cronkite, E.P.; Mount Sinai School of Medicine, New York

1979-01-01

Cascades of Auger electrons are emitted in the decay of 55 Fe and absorbed in tissue within a 1μm radius. Cytocidal amounts of 55 Fe can therefore eliminate erythroid precursors with minimal damage to adjacent cells. A single intravenous injection leads to continued erythrocytocide in mice because the isotope is reutilized and has a 2.7 year half-life. The cytocide evokes an early compensatory response from morphologically unrecognizable precursors which differentiate into pronormoblasts. These early events leave the granuloid series undisturbed but they are accompanied by a precipitous fall in pluripotent stem cell (CFU-S) numbers in bone marrow, spleen, and blood. The pretreatment levels of CFU-S are not restored. Gradual decline of CFU-S is associated with intermittently increased turnover rates and reduced settings of cell production, yet the capacity for quick restoration of blood loss is unimpaired. The precipitous initial stem cell decrease is not caused by irradiation damage, as shown in a separate experimental series that used the frozen-storage cytocide technique. Only over several weeks could 55 Fe radiation accumulate to lethal levels in nondividing stem cells. This irradiation is attributed to incorporation of small amounts of 55 Fe into CFU-S, from where it is slowly cleared. The stem cell loss immediately following 55 Fe injection is in our interpretation caused by rapid differentiation along the erythroid pathway in a response that involves all progenitor populations. Data are consistent with the hypothesis of limited cell renewal capacity which thereby gains further support. (orig.) [de

Full Text Available Purpose: The goal of this material was to be an example of the complications that can occur in cases of zygoma fractures and to draw the attention of the clinicians to the need of accurate diagnose and early treatment of the associated with zygoma fractures traumas. Materials and methods: Medical records of 276 patients with different traumas in face and neck area treated in our department ware reviewed. Of those 64 suffered from zygoma fractures and they ware classified according to age, sex, cause of trauma, presence or absence of associated trauma, etc.Results: As other studies also show, we determined that the most common cause of injury was assault and road accidents, fallowed by sport, industrial, etc. Males between 20 and 40 years old ware the biggest group of patients, often after alcohol consumption.Associated traumas occurred more frequently in cases of motor vehicle accident than in other cases and ware presented by closed head trauma, ophthalmologic problems, extremities fractures, etc.Conclusion: Delayed treatment of zygoma injuries is feasible and yields in good results when the severity of trauma needs it, but early repair of such injuries prevent late complications and should be preferred when possible.

The purpose of this retrospective study was to describe the magnetic resonance imaging (MRI) features of Poly Implant Prothèse (PIP) hydrogel implants in a group of 64 patients and to assess the incidence of rupture, compared to other clinical trials. In this double-center study, we retrospectively reviewed the data sets of 64 consecutive patients (mean age, 43±9 years, age range, 27-65 years), who underwent breast MRI examinations, between January 2008 and October 2013, with suspected implant rupture on the basis of clinical assessment or after conventional imaging examination (either mammography or ultrasound). All patients had undergone breast operation with bilateral textured cohesive gel PIP implant insertion for aesthetic reasons. The mean time after operation was 8 years (range, 6-14 years). No patients reported history of direct trauma to their implants. At the time of clinical examination, 41 patients were asymptomatic, 16 complained of breast tenderness and 7 had clinical evidence of rupture. Normal findings were observed in 15 patients. In 26 patients there were signs of mild collapse, with associated not significant peri-capsular fluid collections and no evidence of implant rupture; in 23 patients there was suggestion of implant rupture, according to breast MRI leading to an indication for surgery. In particular, 14 patients showed intra-capsular rupture, with associated evidence of the linguine sign in all cases; the keyhole sign and the droplet signs were observed in 6 cases. In 9 patients there was evidence of extra-capsular rupture, with presence of axillary collections (siliconomas) in 7 cases and peri-prosthetic and mediastinal cavity siliconomas, in 5 cases. The results of this double center retrospective study, confirm the higher incidence (36%) of prosthesis rupture observed with the PIP implants, compared to other breast implants.

Full Text Available OBJETIVO: avaliar os resultados perinatais em gestantes com mais de 35 anos e verificar diferenças nos grupos entre 35 e 39 anos e acima de 40 anos. MÉTODOS: entre janeiro de 2000 e julho de 2003, realizou-se estudo retrospectivo por análise de fichas obstétricas de 3093 gestantes, excluindo-se 933 gestantes. As pacientes foram divididas em 3 grupos: 18 a 29 anos (grupo controle, 30 a 39 anos e mais de 40 anos. A coleta de dados foi realizada por meio de formulário padronizado e os dados foram transferidos para uma planilha eletrônica (Excel - Microsoft Office 2000. Para a análise estatística, foram utilizados o teste do chi2 e o teste de Fisher, sendo considerado risco a (alfa menor ou igual a 5% e intervalo de confiança de 95%. RESULTADOS: a via de parto mais utilizada para essas pacientes foi a cesárea, tanto no grupo de 35 a 39 anos (438/792; 55,3%, quanto nas gestantes com mais de 40 anos (153/236; 64,8%. A taxa de prematuridade (39/236; 16,5%, o baixo peso ao nascer (37/236; 15,7% e a restrição de crescimento fetal (38/236; 16,1% foram mais altas entre as gestantes tardias, com mais de 40 anos, com diferença significante em relação aos demais grupos.

Methods: Participation and performance trends in athletes by age group in the Badwater (217 km and Spartathlon (246 km races were compared from 2000 to 2012. Results: The number of female and male finishers increased in both races across years (P 0.05. In Spartathlon, the age of the annual five fastest finishers was unchanged at 39.7 ± 2.4 years for men and 44.6 ± 3.2 years for women (P > 0.05. In Badwater, running speed increased in men from 7.9 ± 0.7 km/hour to 8.7 ± 0.6 km/hour (r2 = 0.51, P 0.05. In Badwater, the number of men in age groups 30–34 years (r2 = 0.37, P = 0.03 and 40–44 years (r2 = 0.75, P < 0.01 increased. In Spartathlon, the number of men increased in the age group 40–44 years (r2 = 0.33, P = 0.04. Men in age groups 30–34 (r2 = 0.64, P < 0.01, 35–39 (r2 = 0.33, P = 0.04, 40–44 (r2 = 0.34, P = 0.04, and 55–59 years (r2 = 0.40, P = 0.02 improved running speed in Badwater. In Spartathlon, no change in running speed was observed. Conclusion: The fastest finishers in ultramarathons more than 200 km in distance were 40–45 years old and have to be classified as “master runners” by definition. In contrast to reports of marathoners and ultramarathoners competing in races of 161 km in distance, the increase in participation and the improvement in performance by age group were less pronounced in ultramarathoners competing in races of more than 200 km.

Porting of $\\mu$CernVM to AArch64

CERN Document Server

Scheffler, Felix

2016-01-01

$\\mu$CernVM is a virtual appliance that contains a stripped-down Linux OS connecting to a CernVM-Filesystem (CVMFS) repository that resides on a dedicated web server. In contrast to “usual” VMs, anything that is needed from this repository is only downloaded on demand, aggressively cached and eventually released again. Currently, $\\mu$CernVM is only distributed for x86-64. Recently, ARM (market leader in mobile computing) has started to enter the server market, which is still dominated by x86-64 infrastructure. However, in terms of performance/watt, AArch64 (latest ARM 64bit architecture) is a promising alternative. Facing millions of jobs to compute every day, it is thus desirable to have an HEP virtualisation solution for AArch64. In this project, $\\mu$CernVM was successfully ported to AArch64. Native and virtualised runtime performance was evaluated using ROOT6 and CMS benchmarks. It was found that VM performance is inferior to host performance across all tests. Respective numbers greatly vary between...

Healthy time use in the encore years: do work, resources, relations, and gender matter?

2015-03-01

Social engagement is theorized to promote health, with ages 55 to 75-what some call "encore" adulthood-potentially being a time for ongoing engagement or social isolation. We use the American Time Use Survey (N = 11,952) and a life course perspective to examine associations between paid work, resources, relations, and healthy time use for men and women in the first (55-64) and second (65-74) halves of the encore years. Work limits sufficient sleep (full-time working men) and television watching (all workers) but also time spent in physical activity (full-time workers). College-educated and healthy encore adults-across age and gender divides-are more likely to exercise and watch less television. Marriage and caregiving encourage socializing and limit television watching, despite differential effects on physical activity and sleep. These findings fit well with a gendered life course perspective suggesting socially patterned (by work, resources, relationships, gender, age) health behaviors. © American Sociological Association 2015.

The U.S. Food and Drug Administration has required postapproval studies of silicone breast implants to evaluate the incidence of rare adverse events over 10 years after implantation. The Breast Implant Follow-Up Study is a large 10-year study (>1000 U.S. sites) evaluating long-term safety following primary augmentation, revision-augmentation, primary reconstruction, or revision-reconstruction with Natrelle round silicone breast implants compared with national norms and outcomes with saline implants. Targeted adverse events in subjects followed for 5 to 8 years included connective tissue diseases, neurologic diseases, cancer, and suicide. The safety population comprised 55,279 women (primary augmentation, n = 42,873; revision-augmentation, n = 6837; primary reconstruction, n = 4828; and revision-reconstruction, n = 741). No targeted adverse events occurred at significantly greater rates in silicone implant groups versus national norms across all indications. The standardized incidence rate (observed/national norm) for all indications combined was 1.4 for cervical/vulvar cancer, 0.8 for brain cancer, 0.3 for multiple sclerosis, and 0.1 for lupus/lupus-like syndrome. Silicone implants did not significantly increase the risk for any targeted adverse events compared with saline implants. The risk of death was similar with silicone versus saline implants across all indications. The suicide rate (10.6 events per 100,000 person-years) was not significantly higher than the national norm. No implant-related deaths occurred. Results from 5 to 8 years of follow-up for a large number of subjects confirmed the safety of Natrelle round silicone implants, with no increased risk of systemic disease or suicide versus national norms or saline implants.

64 Cu-diacetyl-bis(N 4 -methylthiosemicarbazone) ( 64 Cu-ATSM) is a promising radiotherapy agent for the treatment of hypoxic tumors. In an attempt to elucidate the radiobiological basis of 64 Cu-ATSM radiotherapy, we have investigated the cellular response patterns in vitro cell line models. Cells were incubated with 64 Cu-ATSM, and the dose-response curves were obtained by performing a clonogenic survival assay. Radiation-induced damage in DNA was evaluated using the alkali comet assay and apoptotic cells were detected using Annexin V-FITC and propidium iodide staining methods. Washout rate and subcellular distribution of 64 Cu in cells were investigated to further assess the effectiveness of 64 Cu-ATSM therapy on a molecular basis. A direct comparison of subcellular localization of Cu-ATSM was made with the flow tracer analog Cu-pyruvladehyde-bis(N 4 -methylthiosemicarbazone). In this study, 64 Cu-ATSM was shown to reduce the clonogenic survival rate of tumor cells in a dose-dependent manner. Under hypoxic conditions, cells took up 64 Cu-ATSM and radioactive 64 Cu was highly accumulated in the cells. In the 64 Cu-ATSM-treated cells, DNA damage by the radiation emitted from 64 Cu was detected, and inhibition of cell proliferation and induction of apoptosis was observed at 24 and 36 h after the treatment. The typical features of postmitotic apoptosis induced by radiation were observed following 64 Cu-ATSM treatment. The majority of the 64 Cu taken up into the cells remained in the postmitochondrial supernatant (the cellular residue after removal of the nuclei and mitochondria), which indicates that the β - particle emitted from 64 Cu may be as effective as the Auger electrons in 64 Cu-ATSM therapy. These data allow us to postulate that 64 Cu-ATSM will be able to attack the hypoxic tumor cells directly, as well as potentially affecting the peripheral nonhypoxic regions indirectly by the β - particle decay of 64 Cu

Activity report of the Neutrino Research Group. Year 2010

International Nuclear Information System (INIS)

2011-01-01

For the last two decades, neutrino physics has been producing major discoveries including neutrino oscillations. These results gave clear confirmation that active neutrinos oscillate and therefore have mass with three different mass states. This is a very important result showing that the Minimal Standard Model is incomplete and requires an extension which is not yet known. The neutrino research field is very broad and active, at the frontier of today's particle physics. The Neutrino Research Group (GDR) was created in January 2005 with the aim of gathering CEA and CNRS research teams working on Neutrino Physics on experimental or theoretical level. This document is the 2010 activity report of the research group, six years after its creation. It presents the results of the 5 working groups: 1 - Determination of neutrino parameters; 2 - Physics beyond the standard model; 3 - Neutrinos in the universe; 4 - Accelerators, detection means, R and D and valorisation; 5 - Common tools to all working groups. The proposed neutrino physics road-map and the actual and future short-, medium- and long-term projects are presented in appendixes

The article presents evaluation of medical demographic and economic losses of population of the Krasnoyarskii kraii conditioned by mortality of lung cancer in 2010-2014 using DALY technology. In the Krasnoyarskii kraii, during 2010-2014 64,712 individuals died because of lung cancer. The mortality of male population surpasses corresponding indices of mortality of females up to 3.9 times. In the region, the standardized indicator mortality of lung cancer among males annually surpasses the same indicator among females at maximum up to 8.1 times. The DALY maximal absolute losses of among males were registered in 2010 and 2013 and fell on age group of 55-59 years and among females on the age group of 60-64 years in 2014. The maximal (up to 5.2 times) difference in values of DALY indicator was established in 2010 between male and female population. the maximal gap in in DALY indices between male and female population was established in the age of 55-59 years. Almost half of DALY losses among males was established in 2013 and among females in 2014. The total losses of gross regional product in the region because of mortality conditioned by lung cancer made up to 29.8 billions of rubles in 2010-2014.

Determinants of locomotor disability in people aged 55 years and over: The Rotterdam study

International Nuclear Information System (INIS)

Odding, Else; Valkenburg, Hans A.; Stam, Hendrik J.; Hofman, Albert

2001-01-01

Locomotor disability, as defined by difficulties in activities of daily living related to lower limb function, can be the consequence of diseases and impairments of the cardiovascular, pulmonary, nervous, sensory and musculoskeletal system. We estimated the associations between specific diseases and impairments and locomotor disability, and the proportion of disability attributable to each condition, controlling for age and comorbidity. The Rotterdam Study is a prospective follow-up study among people aged 55 years and over in the general population. Locomotor disability in 1219 men and 1856 women was assessed with the Stanford Health Assessment Questionnaire. Diseases and impairments were radiological osteoarthritis, pain of the hips and knees, morning stiffness, fractures, hypertension, vascular disease, ischemic heart disease, stroke, heart failure, chronic obstructive pulmonary disease (COPD), depression, Parkinson's disease, osteoporosis, diabetes mellitus, overweight, and low vision. Adjusted odds ratios, etiologic and attributable fractions were calculated for locomotor disability. The occurrence of locomotor disability can partly be ascribed to joint pain, COPD, morning stiffness, diabetes and heart failure in both men and women. In addition in women osteoarthritis, osteoporosis, low vision, fractures, stroke and Parkinson's disease are significant etiologic fractions. In men with morning stiffness, joint pain, heart failure, diabetes mellitus, and COPD a significant proportion of their disability is attributable to this impairment. In women this was the case for Parkinson's disease, morning stiffness, low vision, heart failure, joint pain, diabetes, radiological osteoarthritis, stroke, COPD, osteoporosis, and fractures of the lower limbs, in that order. We conclude that locomotor complaints, heart failure, COPD and diabetes mellitus contribute considerably to locomotor disability in non-institutionalized elderly people

Psychiatric service use has increased in Sweden and in other developed countries, particularly among young people. Possible explanations include lower threshold for help-seeking among young people, but evidence is scarce. We analysed the 2002, 2006 and 2010 Stockholm public health surveys for changes in the mean level of psychological distress among adult users of psychiatric in- and outpatient services in four age groups: 18-24, 25-44, 45-64 and ≥65 years. Psychological distress was measured via the 12-item General Health Questionnaire (GHQ-12), using the Likert scoring method 0-1-2-3. In- and out-patient psychiatric service use within 6 months from the surveys was obtained from registers. The mean level of distress among young adults 18-24 years who utilize psychiatric services decreased between 2002 (mean GHQ-12 score, 95% confidence interval 20.5, 18.1-23.0) and 2010 (16.2, 14.6-17.7), while it remained fairly stable in older age groups. Results were similar in sex-stratified analyses, although the decrease was statistically significant only among young women 18-24 years. At the end of the follow-up, the level of distress among patients was similar for all age-groups. There were no differences between age groups in the level of distress when seeking care at the end of the follow-up period, supporting that there is no age-specific over- or under-consumption of psychiatric care in later years. However, the lowered threshold for help-seeking among young adults over time might have contributed to increases in psychiatric service use in the young age group. Public health policy and service delivery planning should consider the needs of the widening group of young users of psychiatric services.

Full Text Available Octreotide analogues DOTA-TOC and DOTA-TATE were labeled with 64Cu. The influences of the ratio of peptide mass to 64Cu activity, pH value, temperature and reaction time on labeling yield were investigated. The optimum labeling was determined. In vitro stability tests in saline and 10% bovine serum had been carried out. Biodistribution of the two radiolabelled compounds in normal mice and Micro PET imaging in nude mice bearing U87MG tumor had been evaluated. The results showed that the labeling yields of 64Cu-DOTA-TOC and 64Cu-DOTA-TATE were higher than 95%. Two kinds of octreotide analogues labeled with 64Cu were quite stable in saline and decomposed slowly in 10% bovine serum at 37 ℃. Biodistribution results in normal mice showed that two 64Cu labelled tracers had similar profiles. Both of the compounds washed out from the blood quickly. High uptake of radioactivity in liver and kidneys indicated the tracers were excreted via both hepatobiliary system and renal system. At the same time, compared to 64Cu-DOTA-TOC, higher radioactivity accumulation of 64Cu-DOTA-TATE in liver and kidneys was observed. Micro PET images of U87MG tumor-bearing nude mice with 64Cu-DOTA-TOC and 64Cu-DOTA-TATE showed the tumors very clearly. The radioactivity uptake of 64Cu-DOTA-TATE in tumor was higher than that of 64Cu-DOTA-TOC. This work has paved the way for further preclinical and clinical application of 64Cu-DOTA-TOC and 64Cu-DOTA-TATE as PET tumor imaging agents.

Heart rate is one of the most important factors for optimal visualization of cardiac CT. We investigated the relation between heart rate and visibility of the coronary arteries with 64-detector row multislice spiral computed tomography (MSCT). Three simulated coronary artery stenosis models (3, 4, and 5 mm) were attached to a moving heart phantom and scanned using 64-detector row MSCT. The heart rate of the phantom was varied between 60 and 150 beats per minutes (bpm). The visibility of simulated coronary arteries was assessed in comparison between cardiac half reconstruction (CHR) and multi-sector reconstruction (MSR). Then contrast-enhanced 64-detector row MSCT was performed in 16 patients under 3 years of age with congenital heart disease and Kawasaki disease without heart rate control. The visibility of coronary artery segments was graded on a three-point scale. The simulated coronary artery patency was detected in the moving phantom at maximum heart rate (150 bpm) with MSR. Minimum lumen diameter was 0.75 mm. Electrocardiogram (ECG)-gated cardiac CT was performed in 9 patients, and non-ECG-gated cardiac CT was performed in 7 patients. The origin and proximal course of coronary arteries in all 9 patients with ECG-gated acquisition were visually evaluated. 64-detector row MSCT with ECG-gated acquisition is able to visualize the origin and proximal course of coronary arteries in infants under 3 years of age.

The goal of this study was to characterize the relationship between tumor uptake of 64 Cu-DOTA-trastuzumab as measured by PET/CT and standard, immunohistochemistry (IHC)-based, histopathologic classification of human epidermal growth factor receptor 2 (HER2) status in women with metastatic breast cancer (MBC). Methods: Women with biopsy-confirmed MBC and not given trastuzumab for 2 mo or more underwent complete staging, including 18 F-FDG PET/CT. Patients were classified as HER2-positive (HER2+) or -negative (HER2-) based on fluorescence in situ hybridization (FISH)-supplemented immunohistochemistry of biopsied tumor tissue. Eighteen patients underwent 64 Cu-DOTA-trastuzumab injection, preceded in 16 cases by trastuzumab infusion (45 mg). PET/CT was performed 21-25 (day 1) and 47-49 (day 2) h after 64 Cu-DOTA-trastuzumab injection. Radiolabel uptake in prominent lesions was measured as SUV max Average intrapatient SUV max ( pt ) was compared between HER2+ and HER2- patients. Results: Eleven women were HER2+ (8 immunohistochemistry 3+; 3 immunohistochemistry 2+/FISH amplified), whereas 7 were HER2- (3 immunohistochemistry 2+/FISH nonamplified; 4 immunohistochemistry 1+). Median pt for day 1 and day 2 was 6.6 and 6.8 g/mL for HER 2+ and 3.7 and 4.3 g/mL for HER2- patients ( P pt overlapped between the 2 groups, and interpatient variability was greater for HER2+ than HER2- disease ( P DOTA-trastuzumab in MBC is strongly associated with patient HER2 status and is indicative of binding to HER2. The variability within and among HER2+ patients, as well as the overlap between the HER2+ and HER2- groups, suggests a role for 64 Cu-DOTA-trastuzumab PET/CT in optimizing treatments that include trastuzumab. © 2018 by the Society of Nuclear Medicine and Molecular Imaging.

2016-09-01

Full Text Available Interactions between dietary patterns and 2 β-adrenergic receptor (ADRβ gene polymorphisms (ADRβ2 Gln27Glu and ADRβ3 Trp64Arg were examined with regard to the effects on serum triglyceride levels. The cross-sectional study comprised 1720 men and women (aged 35–69 years enrolled in the Japan Multi-Institutional Collaborative Cohort (J-MICC Study. Genotyping was conducted using a multiplex polymerase chain reaction-based invader assay. We used 46 items from a validated short food frequency questionnaire and examined major dietary patterns by factor analysis. We identified four dietary patterns: healthy, Western, seafood and bread patterns. There was no significant association between any dietary pattern and serum triglyceride levels. After a separate genotype-based analysis, significant interactions between ADRβ3 Trp64Arg genotype and the bread pattern (p for interaction = 0.01 were associated with serum triglyceride levels; specifically, after adjusting for confounding factors, Arg allele carriers with the bread pattern had lower serum triglycerides (p for trend = 0.01. However, the Trp/Trp homozygous subjects with the bread pattern showed no association with serum triglycerides (p for trend = 0.55. Interactions between other dietary patterns and ADRβ polymorphisms were not significant for serum triglyceride levels. Our findings suggest that ADRβ3 polymorphism modifies the effects of the bread pattern on triglyceride levels.

Stone, Juliet; Evandrou, Maria; Falkingham, Jane; Vlachantoni, Athina

2015-09-01

Previous research has highlighted the importance of accumulated life-course labour market status and the balancing of multiple roles for understanding inequalities in health in later life. This may be particularly important for women, who are increasingly required to balance work and family life in liberal welfare contexts, such as in Britain. This study analyses retrospective life history data for 2160 women aged 64+ years (born 1909-1943) from the English Longitudinal Study of Ageing, collected in 2006-2007 as part of an ongoing panel study. Optimal matching and cluster analyses are used to produce a taxonomy of women's life-course economic activity trajectories based on their experiences between ages 16 and 64 years. This classification is then used in logistic regression analysis to investigate associations with self-rated health in later life. A set of five trajectories emerge as the dominant patterns of women's economic activity over the life course for those cohorts of English women born prior to 1943: (1) full-time workers; (2) family carers; (3) full-time returners; (4) part-time returners; (5) atypical/inactive. Regression analyses show that women who experience defined periods of full-time work both before and after focusing on family life appear to have the most favourable later life health outcomes. The findings are discussed with reference to the accumulation of social and economic resources over the life course and the balancing of multiple roles in work and family domains. In conclusion, the development of policies that facilitate women, if they wish, to successfully combine paid employment with family life could have a positive impact on their health in later life.

Study of ultraviolet light-induced DNA damage and repair: the role of the (6-4) photoproduct

International Nuclear Information System (INIS)

Franklin, W.A.

1985-01-01

Ultraviolet light induces lethal, mutagenic, and carcinogenic effects to cells. These effects are a result of the induction of photoproducts in the cellular DNA. One class of photoproducts was found as alkaline labile lesions in DNA, and it was proposed that such lesions were precursor products to the 6,4'-[pyrimidin-2'-one]-pyrimidine class of photoproducts that have been previously shown to occur in UV light-irradiated DNA. Using a series of dinucleotide compounds, the precursor compounds were isolated, and were demonstrated to be alkaline labile. These products were named the UV light-induced pyrimidine-pyrimidone (6-4) photoproducts, and their chemistry of formation in dinucleotides and DNA was studied. The formation of these photoproducts under conditions of chemical photosensitization was also measured. The most abundant of the (6-4) photoproducts is the thymine-cytosine (6-4) product, and the molecular structure of this compounds was determined by the use of infrared spectroscopy, proton NMR, and mass spectroscopy. The (6-4) products have been recently shown to be the major UV light-induced premutagenic lesions in E. coli. In E. coli, the repair of the (6-4) products is under the control of the uvrABC excision pathway. The rate of removal of (6-4) products was measured in a series of human cells lines. The rate of removal of (6-4) products from the DNA of a xeroderma pigmentosum complementation group A cell line was nearly that of the normal cells, yet these cells are unable to excise cyclobutane pyrimidine dimers. These results suggest that the removal of cyclobutane pyrimidine dimers and (6-4) products may be controlled by separate enzymatic pathways

A look at the density functional theory zoo with the advanced GMTKN55 database for general main group thermochemistry, kinetics and noncovalent interactions.

We present the GMTKN55 benchmark database for general main group thermochemistry, kinetics and noncovalent interactions. Compared to its popular predecessor GMTKN30 [Goerigk and Grimme J. Chem. Theory Comput., 2011, 7, 291], it allows assessment across a larger variety of chemical problems-with 13 new benchmark sets being presented for the first time-and it also provides reference values of significantly higher quality for most sets. GMTKN55 comprises 1505 relative energies based on 2462 single-point calculations and it is accessible to the user community via a dedicated website. Herein, we demonstrate the importance of better reference values, and we re-emphasise the need for London-dispersion corrections in density functional theory (DFT) treatments of thermochemical problems, including Minnesota methods. We assessed 217 variations of dispersion-corrected and -uncorrected density functional approximations, and carried out a detailed analysis of 83 of them to identify robust and reliable approaches. Double-hybrid functionals are the most reliable approaches for thermochemistry and noncovalent interactions, and they should be used whenever technically feasible. These are, in particular, DSD-BLYP-D3(BJ), DSD-PBEP86-D3(BJ), and B2GPPLYP-D3(BJ). The best hybrids are ωB97X-V, M052X-D3(0), and ωB97X-D3, but we also recommend PW6B95-D3(BJ) as the best conventional global hybrid. At the meta-generalised-gradient (meta-GGA) level, the SCAN-D3(BJ) method can be recommended. Other meta-GGAs are outperformed by the GGA functionals revPBE-D3(BJ), B97-D3(BJ), and OLYP-D3(BJ). We note that many popular methods, such as B3LYP, are not part of our recommendations. In fact, with our results we hope to inspire a change in the user community's perception of common DFT methods. We also encourage method developers to use GMTKN55 for cross-validation studies of new methodologies.

Purpose To examine the association of health-related quality of life (HRQoL) with severity of visual impairment among people aged 40–64 years. Methods We used cross-sectional data from the 2006–2010 Behavioral Risk Factor Surveillance System to examine six measures of HRQoL: self-reported health, physically unhealthy days, mentally unhealthy days, activity limitation days, life satisfaction, and disability. Visual impairment was categorized as no, a little, or moderate/severe. We examined the association between visual impairment and HRQoL using logistic regression accounting for the survey’s complex design. Results Overall, 23.0% of the participants reported a little difficult seeing, while 16.8% reported moderate/severe difficulty seeing. People aged 40–64 years with moderate/severe visual impairment had more frequent (≥14) physically unhealthy days, mentally unhealthy days, and activity limitation days in the last 30 days, as well as greater life dissatisfaction, greater disability, and poorer health compared to people reporting no or a little visual impairment. After controlling for covariates (age, sex, marital status, race/ethnicity, education, income, state, year, health insurance, heart disease, stroke, heart attack, body mass index, leisure-time activity, smoking, and medical care costs), and compared to people with no visual impairment, those with moderate/severe visual impairment were more likely to have fair/poor health (odds ratio, OR, 2.01, 95% confidence interval, CI, 1.82–2.23), life dissatisfaction (OR 2.06, 95% CI 1.80–2.35), disability (OR 1.95, 95% CI 1.80–2.13), and frequent physically unhealthy days (OR 1.69, 95% CI 1.52–1.88), mentally unhealthy days (OR 1.84, 95% CI 1.66–2.05), and activity limitation days (OR 1.94, 95% CI 1.71–2.20; all p visual impairment among people aged 40–64 years.

The objective of our study was to compare the diagnostic accuracy of IV contrast-enhanced 64-MDCT with and without the use of oral contrast material in diagnosing appendicitis in patients with abdominal pain. We conducted a randomized trial of a convenience sample of adult patients presenting to an urban academic emergency department with acute nontraumatic abdominal pain and clinical suspicion of appendicitis, diverticulitis, or small-bowel obstruction. Patients were enrolled between 8 am and 11 pm when research assistants were present. Consenting subjects were randomized into one of two groups: Group 1 subjects underwent 64-MDCT performed with oral and IV contrast media and group 2 subjects underwent 64-MDCT performed solely with IV contrast material. Three expert radiologists independently reviewed the CT examinations, evaluating for the presence of appendicitis. Each radiologist interpreted 202 examinations, ensuring that each examination was interpreted by two radiologists. Individual reader performance and a combined interpretation performance of the two readers assigned to each case were calculated. In cases of disagreement, the third reader was asked to deliver a tiebreaker interpretation to be used to calculate the combined reader performance. Final outcome was based on operative, clinical, and follow-up data. We compared radiologic diagnoses with clinical outcomes to calculate the diagnostic accuracy of CT in both groups. Of the 303 patients enrolled, 151 patients (50%) were randomized to group 1 and the remaining 152 (50%) were randomized to group 2. The combined reader performance for the diagnosis of appendicitis in group 1 was a sensitivity of 100% (95% CI, 76.8-100%) and specificity of 97.1% (95% CI, 92.7-99.2%). The performance in group 2 was a sensitivity of 100% (73.5-100%) and specificity of 97.1% (92.9-99.2%). Patients presenting with nontraumatic abdominal pain imaged using 64-MDCT with isotropic reformations had similar characteristics for the

2015-08-01

Full Text Available In this work, the Liquid Impingement Erosion (LIE performances of deep-rolling (DR treated and non-treated Ti64 were investigated. Various erosion stages, from the incubation to the terminal erosion stages, could be observed. A full factorial design of experiments was used to study the effect of DR process parameters (Feed Rate, Spindle Velocity, Number of Passes, Pressure on the residual stress distribution, microhardness and surface roughness of the treated Ti64 specimens. The DR-treated Ti64 specimens exhibited improved surface microhardness, surface roughness, and large magnitude of compressive residual stresses, which were attributed to the amount of cold work induced by the DR process. Although DR improved the mechanical properties of the Ti64, the results showed that the treatment has little or no effect on the LIE performance of Ti64 but different damage modes were observed in these two cases. Evolution of the erosion stages was described based on water-hammer pressure, stress waves, radial wall jetting, and hydraulic penetration modes. The initial erosion stages were mainly influenced by water-hammer pressure and stress waves, whereas the intermediate erosion stages were influenced by the combination of the four modes together. The final erosion stages contain the four modes, however the erosion was greatly driven by the radial jetting and hydraulic penetration modes, where more material was removed. The failure mechanism of the final stages of the LIE test of both DR-treated and non-treated Ti64 was characterized as fatigue fracture. However, a brittle fracture behavior was observed in the initial and intermediate erosion stages of the DR-treated Ti64, whereas a ductile fracture behavior was observed in the non-treated Ti64. This was concluded from the micrographs of the LIE damage through different erosion stages.

Optimized preparation and preliminary evaluation of [64Cu]-DOTA-trastuzumab for targeting ErbB2/Neu expression

International Nuclear Information System (INIS)

Behrooz Alirezapour; Mohammad Javad Rasaee

2013-01-01

Breast cancer radioimmunoscintigraphy targeting HER2/neu expression is a growing field of work in nuclear medicine research. Trastuzumab is a monoclonal antibody that binds with high affinity to HER2/neu, which is over expressed on breast and other tumors. Developing new tracers for the detection of this cancer is of great interest. In this study, trastuzumab was successively labeled with [ 64 Cu]CuCl 2 after conjugation with DOTA-NHS-ester. The conjugate was purified by molecular filtration, the average number of DOTA conjugated per mAb was calculated and total concentration was determined by spectrophotometric method. DOTA-trastuzumab was labeled with 64 Cu produced by 68 Zn(p,αn) 64 Cu nuclear reaction (30 MeV protons at 180 μA). Radiochemical purity, integrity of protein after radiolabeling and immunoreactivity of radiolabeled mAb trastuzumab with HER2/neu antigen and SkBr3 cell line were performed by RIA. In vitro stability of radiolabeled mAb in human serum was determined by thin layer chromatography. In vitro internalization studies were performed with the SkBr3 cell line and the tissue biodistribution of the 64 Cu-DOTA-trastuzumab was evaluated in wild-type rat (90 ± 5.5 μCi, 2, 6, 12, 24 h p.i.). The radioimmunoconjugate was prepared with a radiochemical purity of higher than 96 ± 0.5 % (ITLC) and specific activity as high as 5.3 μCi/μg. The average number of chelators per antibody for the conjugate used in this study was 5.8/1. The sample was showed to have similar patterns of migration in the gel electrophoresis. The 64 Cu-DOTA-trastuzumab showed high immunoreactivity towards HER2/neu antigen and SkBr3 cell line. In vitro stability of the labeled product was found to be more than 94 % in PBS and 82 ± 0.5 % in human serum over 48 h. In vitro internalization studies of the 64 Cu-DOTA-trastuzumab showed that up to 11.5 % of the radioimmunoconjugate internalized after 10 h.

High doses of 55 Fe induced cytocide in maturing erythroid cells, due to the short-range deposition of decay energy. Organ damage at the time of death was evaluated in a group of 45 female mice of the C 57 BL/6 J strain given a single i.v. injection of 2,800 μCi, 1,400 μCi or 700 μCi of 55 FeCl 3 when 10 to 14 weeks old. A corresponding amount of cold iron was given to control animals by the same route. Radioiron-treated mice died spontaneously, or were killed when moribund. Mice given 2,800 μCi died after a median survival time of 27 days with severe depletion of hemopoietic cells in bone marrow and spleen, marked atrophy of lymphoid tissues and mild liver damage. After 1,400 μCi or 700 μCi, the median survival time was 117 and 439, respectively. In contrast, median survival was 847 days in control animals allowed to survive. In the two lower 55 Fe-dose groups, there was a dose-dependent pancytopenia. Atrophy of lymphoid tissues was moderate, and signs of liver damage slight. The degree of organ hemosiderosis in experimental and control animals was slight to moderate. Organ damage associated with deposition of cold iron was not apparent in tissue sections. Morphological signs of damage to non-hemopoietic organs such as the liver were not conspicuous. Direct radiation damage, primarily to the erythroid series, and competition for stem cells between the heavily depleted erythroid and the other hemopoietic cell lines must be considered among the possible factors leading to pancytopenia. Out of 14 55 Fe-treated mice who survived longer than 300 days developed tumors of hemopoietic and lymphoid tissues, or osteosarcomas. (orig./MG) [de

The present case report describes a 6-year old subfertile pony mare, which became pregnant after the eleventh artificial insemination. The examination of the ovaries and the uterus did not reveal any abnormal clinical findings and the mare showed a regular oestrous cycle. Based on cytogenetic and molecular genetic analyses it became possible to elucidate the observed subfertility. The mosaic karyotype of the mare consisted of 63,X (20%) and 64,XX (80%) cells. A PCR analysis failed to amplify sequences from the equine SRY gene. The observed classic 63,X/64,XX mosaicism is a plausible explanation for the subfertility of the mare.

Ou, Phalla; Marini, Davide; Celermajer, David S.; Agnoletti, Gabriella; Vouhe, Pascal; Sidi, Daniel; Bonnet, Damien; Brunelle, Francis

2009-01-01

Background: Management of congenital pulmonary vein stenosis is a diagnostic challenge. Echocardiography may be insufficient and thus cardiac catheterization remains the reference standard in this setting. The aim of the study was to investigate the accuracy of cardiac-non-gated CT using 64-slice technology in detecting congenital pulmonary vein stenosis in children. Materials and methods: CT examinations were consecutively performed from May 2005 to December 2006 in 13 children aged 1.5-12 months (median 5 months) for suspected congenital pulmonary vein stenosis. Cardiac-non-gated CT acquisitions were performed after the peripheral injection of contrast agent. Pulmonary veins were evaluated for their pattern of connectivity from the lung to the left atrium and for the presence of stenosis. CT findings of pulmonary vein stenosis were compared with combined findings available from echocardiography, catheterization and surgery. Results: Pulmonary veins from the right lung (n = 29) and left lung (n = 26) were evaluated as separate structures (N = 55). Of the 55 structures, 32 had surgical and/or catheterization data and 45 had echocardiography for comparison. CT visualized 100% (55/55) of the investigated structures, while echocardiography visualized 82% (45/55). In the 13 subjects CT identified 10 stenotic pulmonary veins. CT confirmed the echocardiography suspicion of pulmonary vein stenosis in 100% (7/7) and established a new diagnosis in 3 other patients. CT agreed with surgery/catheterization in 100% (10/10) of the available comparisons. Conclusion: Cardiac-non-gated CT assessed the pulmonary veins more completely than echocardiography and should be considered as a viable alternative for invasive pulmonary venography for detecting pulmonary vein stenosis in children.

Objective In this study we aimed to assess the image quality and degree of vascular enhancement using low-concentration contrast media (LCCM) (300 mg I ml–1) and high-concentration contrast media (HCCM) (370 mg I ml–1) on 64-slice multidetector row CT (MDCT) abdominal CT angiography (CTA). In addition, we aimed to study the feasibility of using HCCM with a reduced total iodine dose. Methods CTA of the abdomen on a 64-slice MDCT was performed on 15 anaesthetised pigs. Study pigs were divided into three groups of five each based on the iodine concentration and dose received: Group A (LCCM; 300 mg I ml–1), Group B (HCCM; 370 mg I ml–1) and Group C HCCM with 20% less iodine dose. The total iodine injected was kept constant (600 mg kg–1) in Groups A and B. Qualitative and quantitative analyses were performed to study and compare each group for image quality, visibility of the branch order of the superior mesenteric artery (SMA), artefacts, degree of enhancement in the aorta and main stem arteries and uniformity of enhancement in the aorta. Groups were compared using the analysis of variance test. Results The image quality of 64-slice MDCT angiography was excellent with a mean score of 4.63 and confident visualisation of the third to fifth order branches of the SMA in all groups. Group B demonstrated superior vascular enhancement, as compared with Groups A and C (p≤0.05). Uniform aortic enhancement was achieved with the use of LCCM and HCCM with 20% less iodine dose. Conclusion 64-slice MDCT angiography of the abdomen was of excellent quality. HCCM improves contrast enhancement and overall CTA image quality and allows the iodine dose to be reduced. PMID:21081582

On the Sizes of the North Atlantic Basin Tropical Cyclones Based on 34- and 64-kt Wind Radii Data, 2004-2013

At end of the 2012 hurricane season the National Hurricane Center retired the original HURDAT dataset and replaced it with the newer version HURDAT2, which reformatted the original data and included additional information, in particular, estimates of the 34-, 50, and 64-kt wind radii for the interval 2004-2013. During the brief 10-year interval, some 164 tropical cyclones are noted to have formed in the North Atlantic basin, with 77 becoming hurricanes. Hurricane Sandy (2012) stands out as being the largest individual storm that occurred in the North Atlantic basin during the 2004 -2013 timeframe, both in terms of its 34- and 64-kt wind radii and wind areas, having maximum 34- and 64-kt wind radii, maximum wind areas, and average wind areas each more than 2 standard deviations larger than the corresponding means. In terms of the largest yearly total 34-kt wind area (i.e., the sum of all individual storm 34-kt wind areas during the year), the year 2010 stands out as being the largest (about 423 × 10(exp 6) nmi(exp 2)), compared to the mean of about 174 × 10(exp 6) nmi(exp 2)), surpassing the year 2005 (353 x 10(exp 6) nmi(exp 2)) that had the largest number of individual storms (28). However, in terms of the largest yearly total 64-kt wind area, the year 2005 was the largest (about 9 × 10(exp 6) nmi(exp 2)), compared to the mean of about 3 × 106 nmi(exp 2)). Interesting is that the ratio of total 64-kt wind area to total 34-kt wind area has decreased over time, from 0.034 in 2004 to 0.008 in 2013.

{sup 64}Cu (T{sub 1/2} = 12.7 h, 37.1% {beta}{sup -}, {beta}{sup +} 17.9%) is a suitable radioisotope for use in positron emission tomography, due to its physical properties, which make it ideal for therapy ({beta}{sup -}) and for use in diagnosis ({beta}{sup +}), e.g. of hypoxic tumors. Its production is possible in biomedical cyclotrons (with protons' energy 11-18 MeV). We used for its preparation a nuclear reaction {sup 64}Ni(p,n) because it has a large cross section also at the energies of small biomedical cyclotrons. A disadvantage of this reaction is the high price of the target material, eliminated by developing a very simple way of {sup 64}Ni recycling. Ion exchange chromatography (adsorbent Bio-Rad AG1-X8) was used for separation of {sup 64}Cu from target material. Separation was carried out on the separation module developed by us. Yield of {sup 64}Cu for 100 mg {sup 64}Ni (99.09%) on the gold target was 104 MBq /{mu}Ah. To measure the product activity and for determination of radioisotope contamination there were used: a ionization chamber (Curiementor), gamma-spectrometry (HPGe detector) and liquid scintillation spectrometry (TDCR method).

We aimed to analyze preoperative and intraoperative clinical characteristics of chronic perforated otitis media by patient age. We analyzed 137 tympanoplasties for chronic perforated otitis media in 133 patients. Exclusion criteria were ear adhesions, cholesteatoma, and a history of tympanoplasty. Patients were divided into a younger group (aged 15-39 years), a middle group (40-64 years), and an elderly group (≥65 years). We compared tympanoplasty technique (using Wullstein classification), mastoid air-cell area measured by temporal bone computed tomography, preoperative aeration of the temporal bone, mean preoperative hearing (at 500 Hz, 1000 Hz, and 2000 Hz), and patch effect calculated by the pre- and post-patch air-bone gap at frequencies of 250 Hz and 500 Hz among the three age groups. Although type I tympanoplasty was performed most frequently in all age groups, it was performed significantly less often in the elderly group (pgroup (page groups (pgroups. The mean patch effect was significantly better in the younger group than in middle or elderly groups (p<0.05). The less pneumatized mastoid and ossicular diseases in elderly patients with chronic perforated otitis media suggest that they had longer lasting and more severe childhood middle ear pathologies than did younger patients.

Bae, Eun-Jung; Kim, Yun-Hee

2017-06-01

This study aimed to investigate factors affecting sarcopenia in different age groups among Korean adults aged 20 years or older. In this secondary analysis, data were collected from records for 17,968, participants who participated in the Korea National Health and Nutrition Examination Survey during 2008-2011. Data were analyzed using multiple logistic regression to determine the associated factors of sarcopenia by age groups. The prevalence of sarcopenia increased significantly with age. Physical activity, blood pressure, waist circumference, triglycerides, vitamin D level were found to be factors significantly associated with sarcopenia in all age groups. Total energy intake was found to be a factor that is significantly associated with sarcopenia among the adults aged 20-39 years. Fasting glucose, suicidal ideation, perceived health status, mobility problem, pain/discomfort, total energy intake were found to be factors associated with sarcopenia in the adults aged 40-64 years. Sex, residential area, smoking, drinking, fasting glucose, osteoarthritis, fall experience, usual activity problem, protein intake were factors associated with sarcopenia in the adults over 65 years of age. The findings show that sarcopenia in adults and the associated factors were different by age groups. Thus, these factors should be considered in the development of intervention programs for the care and prevention of sarcopenia, and such programs should be modified according to different age groups.

High-fructose corn syrup-55 (HFCS-55) has been suggested to be more lipogenic than sucrose, which increases the risk for nonalcoholic fatty liver disease (NAFLD) and dyslipidemia. The study objectives were to determine the effects of drinking different sugar-sweetened solutions on hepatic gene expression in relation to liver fatty acid composition and risk of NAFLD. Female rats were randomly assigned (n=7 rats/group) to drink water or water sweetened with 13% (w/v) HFCS-55, sucrose or fructose for 8 weeks. Rats drinking HFCS-55 solution had the highest (P=.03) hepatic total lipid and triglyceride content and histological evidence of fat infiltration. Rats drinking HFCS-55 solution had the highest hepatic de novo lipogenesis indicated by the up-regulation of stearoyl-CoA desaturase-1 and the highest (Ptriglyceride-rich lipoprotein from the liver was increased as shown by up-regulation of gene expression of microsomal triglyceride transfer protein in rats drinking sucrose, but not HFCS-55 solution. The observed lipogenic effects were attributed to the slightly higher fructose content of HFCS-55 solution in the absence of differences in macronutrient and total caloric intake between rats drinking HFCS-55 and sucrose solution. Results from gene expression and fatty acid composition analysis showed that, in a hypercaloric state, some types of sugars are more detrimental to the liver. Based on these preclinical study results, excess consumption of caloric sweetened beverage, particularly HFCS-sweetened beverages, should be limited. Published by Elsevier Inc.

Usefulness of Desirable Lifestyle Factors to Attenuate the Risk of Heart Failure Among Offspring whose Parents had Myocardial Infarction before Age 55 Years

Science.gov (United States)

Khawaja, Owais; Kotler, Gregory; Gaziano, John Michael; Djoussé, Luc

2012-01-01

Heart failure (HF) is one of the leading causes of hospitalization and death in United States and throughout Europe. While a higher risk of HF with antecedent myocardial infarction (MI) has been reported in offspring whose parents had MI before age 55, it is unclear whether adherence to healthful behaviors could mitigate that risk. The aim of the current study was therefore to prospectively examine if adherence to healthy weight, regular exercise, moderate alcohol consumption, and abstinence from smoking can attenuate such increased HF risk. The information on parental history of MI and lifestyle factors was collected using questionnaires. Subjects adhering to at least three healthy lifestyle factors were classified as having good vs. poor lifestyle score. Incident HF was assessed via yearly follow-up questionnaires and validated in a subsample. During an average follow up of 21.7 (6.5) years, 1,323 new HF cases (6.6%) of which 190 (14.4%) were preceded by MI occurred. Compared to subjects with good lifestyle score and no parental history of premature MI, multivariable adjusted hazard ratios (95% CI) for incident HF with antecedent MI was 3.21 (1.74–5.91) for people with good lifestyle score and parental history of premature MI; 1.52 (1.12–2.07) for individuals with poor lifestyle score and no parental history of premature MI; and 4.60 (2.55–8.30) for people with poor lifestyle score and parental history of premature MI. In conclusion, our data suggest that even in people at higher risk of HF due to genetic predisposition, adherence to healthful lifestyle factors may attenuate such an elevated HF risk. PMID:22516528

BACKGROUND: The aim of this study was to estimate the cost effectiveness of screening for abdominal aortic aneurysm (AAA). MATERIAL AND METHODS: All 12,639 men born in the years 1921-1933 (aged 64-73) living in Viborg County, Denmark, were randomly allocated either to receive an invitation...... to abdominal ultrasound scanning for AAA or to be controls. Costs for screening and surveillance were assessed prospectively. Diagnosis Related Group (DRG) costs from 1999 were used concerning admissions with uncomplicated and complicated operations. Admissions for AAA surgery were retrospectively classified...... group (P = 0.003). The costs were estimated to be Euro 11.23 per scan. The costs per life-year saved were Euro 9057 (Euro 5872-20,063) after 5 years, and were expected to decrease to Euro 2708 (Euro 1758-6031) after 10 years and to Euro 1825 (Euro 1185-4063) after 15 years. CONCLUSION: Screening of 64...

Risk groups for yellow fever vaccine-associated viscerotropic disease (YEL-AVD).

Science.gov (United States)

Seligman, Stephen J

2014-10-07

Although previously considered as the safest of the live virus vaccines, reports published since 2001 indicate that live yellow fever virus vaccine can cause a severe, often fatal, multisystemic illness, yellow fever vaccine-associated viscerotropic disease (YEL-AVD), that resembles the disease it was designed to prevent. This review was prompted by the availability of a listing of the cumulative cases of YEL-AVD, insights from a statistical method for analyzing risk factors and re-evaluation of previously published data. The purpose of this review is to identify and analyze risk groups based on gender, age, outcome and predisposing illnesses. Using a passive surveillance system in the US, the incidence was reported as 0.3 to 0.4 cases per 100,000. However, other estimates range from 0 to 12 per 100,000. Identified and potential risk groups for YEL-AVD include elderly males, women between the ages of 19 and 34, people with a variety of autoimmune diseases, individuals who have been thymectomized because of thymoma, and infants and children ≤11 years old. All but the last group are supported by statistical analysis. The confirmed risk groups account for 77% (49/64) of known cases and 76% (32/42) of the deaths. The overall case fatality rate is 66% (42/64) with a rate of 80% (12/15) in young women, in contrast to 50% (13/26) in men ≥56 years old. Recognition of YEL-AVD raises the possibility that similar reactions to live chimeric flavivirus vaccines that contain a yellow fever virus vaccine backbone could occur in susceptible individuals. Delineation of risk groups focuses the search for genetic mutations resulting in immune defects associated with a given risk group. Lastly, identification of risk groups encourages concentration on measures to decrease both the incidence and the severity of YEL-AVD. Copyright © 2014 Elsevier Ltd. All rights reserved.

55Co level properties

Lodin, G.; Nilsson, L.; Erlandsson, B.; Lyttkens, J.

1975-01-01

The decay pf low-lying levels in 55 Co has been studied by means of the 54 Fe(d,nγ) 55 Co reaction. Neutron energies were determined by time-of-flight techniques using a pulsed incident beam and a large liquid scintillator. Gamma rays in coincidence with neutrons were detected by a Ge(Li)spectrometer, Three levels at 4720.8+-0.6, 4747.1+-0.6 and 5172.4+-0.6 keV were strongly populated. The 4720 and 5172 keV levels have earlier been identified as the isobaric analogues of the 55 Fe ground state and first excited state. On the basis of a comparison of the present results with previous particle-transfer reaction studies it is suggested that the ground state analogue is split into the 4720 and 4747 keV levels. A study of excitation functions of 54 Fe(d,n)transitions at incident deuteron energies between 5.0 and 6.0 MeV show that the spectroscopic strengths obtained from (d,n) experiments in this mass region at these energies depend strongly on the incident energy.

MLN64 induces mitochondrial dysfunction associated with increased mitochondrial cholesterol content

Directory of Open Access Journals (Sweden)

Elisa Balboa

2017-08-01

Full Text Available MLN64 is a late endosomal cholesterol-binding membrane protein that has been implicated in cholesterol transport from endosomal membranes to the plasma membrane and/or mitochondria, in toxin-induced resistance, and in mitochondrial dysfunction. Down-regulation of MLN64 in Niemann-Pick C1 deficient cells decreased mitochondrial cholesterol content, suggesting that MLN64 functions independently of NPC1. However, the role of MLN64 in the maintenance of endosomal cholesterol flow and intracellular cholesterol homeostasis remains unclear. We have previously described that hepatic MLN64 overexpression increases liver cholesterol content and induces liver damage. Here, we studied the function of MLN64 in normal and NPC1-deficient cells and we evaluated whether MLN64 overexpressing cells exhibit alterations in mitochondrial function. We used recombinant-adenovirus-mediated MLN64 gene transfer to overexpress MLN64 in mouse liver and hepatic cells; and RNA interference to down-regulate MLN64 in NPC1-deficient cells. In MLN64-overexpressing cells, we found increased mitochondrial cholesterol content and decreased glutathione (GSH levels and ATPase activity. Furthermore, we found decreased mitochondrial membrane potential and mitochondrial fragmentation and increased mitochondrial superoxide levels in MLN64-overexpressing cells and in NPC1-deficient cells. Consequently, MLN64 expression was increased in NPC1-deficient cells and reduction of its expression restore mitochondrial membrane potential and mitochondrial superoxide levels. Our findings suggest that MLN64 overexpression induces an increase in mitochondrial cholesterol content and consequently a decrease in mitochondrial GSH content leading to mitochondrial dysfunction. In addition, we demonstrate that MLN64 expression is increased in NPC cells and plays a key role in cholesterol transport into the mitochondria.

Earlier scales on mindful eating do not measure mindful eating independent from emotional or external eating, or mindful eating in common situations. The objective was to develop a new instrument to measure the attention element of mindful eating, the Mindful Eating Behavior Scale (MEBS), and to compute the internal structure, reliabilities, and convergent validity of this scale. A cross-sectional ancillary study within the Longitudinal Aging Study Amsterdam was conducted between fall 2014 and spring 2015. Participants were 1,227 Dutch adults aged 55 years and older from the Longitudinal Aging Study Amsterdam. A selection of 20 items from existing instruments was used to design an initial version of the MEBS. The internal structure of the MEBS was evaluated using an exploratory structural equation modeling approach on half of the sample and confirmatory factor analysis on the whole sample to develop the final version of the scale. The measurement invariance of the scores was tested with respect to sex, age, and body mass index. Reliabilities of subscales were determined with Cronbach's α. To test convergent validity, the scores of the new scale were correlated with theoretically relevant variables. Two items were deleted because of low item loadings and one item because of high correlated uniqueness. The final confirmatory factor analysis model with 17 items and four domains (Focused Eating, Hunger and Satiety Cues, Eating with Awareness, and Eating without Distraction) showed good fit (comparative fit index=0.97, Tucker-Lewis index=0.96, and root mean square error of approximation=0.04). Measurement invariance was found for sex, age, and body mass index. Cronbach's α values were medium to high (.70 to .89). Most correlations were in the expected directions, which indicated good preliminary convergent validity. The MEBS was successfully developed consisting of 17 items and four domains. Because of low interfactor correlations, a total score combining the four

Diabetes education through group classes leads to better care and outcomes than individual counselling in adults: a population-based cohort study.

Self-management education, supported by multidisciplinary health care teams, is essential for optimal diabetes management. We sought to determine whether acute diabetes complications or quality of care differed for patients in routine clinical care when their self-management education was delivered through group diabetes education classes versus individual counselling. With the use of population-level administrative and primary data, all diabetic patients in Ontario who attended a self-management education program in 2006 were identified and grouped according to whether they attended group classes (n=12,234), individual counselling (n=55,761) or a mixture of both (n=9,829). Acute complications and quality of care in the following year were compared among groups. Compared with those attending individual counselling, patients who attended group classes were less likely to have emergency department visits for hypo/hyperglycemia (odds ratio 0.54, 95% confidence interval [CI]: 0.42-0.68), hypo/hyperglycemia hospitalizations (OR 0.49, CI: 0.32-0.75) or foot ulcers/cellulitis (OR 0.64, CI: 0.50-0.81). They were more likely to have adequate HbA1c testing (OR 1.10, CI: 1.05-1.15) and lipid testing (OR 1.25, CI: 1.19-1.32), and were more likely to receive statins (OR 1.22, CI: 1.07-1.39). Group self-management education was associated with fewer acute complications and some improvements in processes of care. Group sessions can offer care to more patients with reduced human resource requirements. With increased pressure to find efficiencies in health care delivery, group diabetes education may provide an opportunity to deliver less resource-intensive care that simultaneously improves patient care.

Modifications to the application of pressure to a quarter of the circumference of panel rings (tests 54 and 55)

Energy Technology Data Exchange (ETDEWEB)

Van Duyse, H [INIEX

1978-01-01

Tests 54 and 55 were carried out on rings made up of the usual type of panel. Test 54 involved panels manufactured at Zolder and Test 55 involved those manufactured at Beringen. Both types of ring are 20 cm thick, 64 cm wide and have an internal diameter of 4.20 m. The tests involved application of pressure to one quarter of the circumference, the remainder of the ring being subject to restraint against the steel testing frame. Timber chocks were inserted between the ring and the frame. The reinforcements tested were those used with the normal type of panel. An account of deformation of the ring, cracking of the panels, and deformation of the concrete is given. Tables and figures summarizing the results achieved are included. Maximum load prior to breaking was 292 t in the case of the Zolder ring and 293 t in the case of the Beringen ring; initial cracking occurred at 35 and 30 t, respectively. (In French and in Dutch)

The rat L5/6 facet joint is multisegmentally innervated from the L1 to L6 dorsal root ganglia (DRG). Tumor necrosis factor (TNF) is a known mediator of inflammation. It has been reported that satellite cells are activated, produce TNF and surround DRG neurons innervating L5/6 facet joints after facet injury. In the current study, changes in TNF receptor (p55) expression in DRG neurons innervating the L5/6 facet joint following facet joint injury were investigated in rats using a retrograde neurotransport method followed by immunohistochemistry. Twenty rats were used for this study. Two crystals of Fluorogold (FG; neurotracer) were applied into the L5/6 facet joint. Seven days after surgery, the dorsal portion of the capsule was cut in the injured group (injured group n = 10). No injury was performed in the non-injured group (n = 10). Fourteen days after the first application of FG, bilateral DRGs from T13 to L6 levels were resected and sectioned. They were subsequently processed for p55 immunohistochemistry. The number of FG labeled neurons and number of FG labeled p55-immunoreactive (IR) neurons were counted. FG labeled DRG neurons innervating the L5/6 facet joint were distributed from ipsilateral L1 to L6 levels. Of FG labeled neurons, the ratio of DRG neurons immunoreactive for p55 in the injured group (50%) was significantly higher than that in the non-injured group (13%). The ratio of p55-IR neurons of FG labeled DRG neurons was significantly higher in total L1 and L2 DRGs than that in total L3, 4, 5 and 6 DRGs in the injured group (L1 and 2 DRG, 67%; L3, 4, 5 and 6 DRG, 37%, percentages of the total number of p55-IR neurons at L1 and L2 level or L3-6 level/the total number of FG-labeled neurons at L1 and L2 level or L3-6 level). These data suggest that up-regulation of p55 in DRG neurons may be involved in the sensory transmission from facet joint injury. Regulation of p55 in DRG neurons innervating the facet joint was different between upper DRG innervated

INFLUENCE OF AGE ON SWALLOWS OF A HIGHLY VISCOUS LIQUID BOLUS

Directory of Open Access Journals (Sweden)

Weslania Viviane NASCIMENTO

2015-03-01

Full Text Available Background Swallow function has a decline with aging, mainly in those over 80 years old. In the population over 69 years, about 11% of subjects reported symptoms indicative of significant dysphagia. Objectives Our objective was to evaluate the hypothesis that older asymptomatic subjects before 80 years old have compensations to sustain a safe and efficient swallow, at least with swallows of liquid bolus. Methods We performed videofluoroscopic evaluation of swallows in 55 normal volunteers, a younger group with 33 subjects (16 men and 17 women aged 19 to 55 years, mean 35.5±9.8 years, and an older group with 22 subjects (15 men and 7 women aged 56 to 77 years, mean 64.8±6.8 years. The subjects swallowed in duplicate 5 mL and 10 mL of liquid barium with a pH of 7.9, density of 1.82 g/cm3, and viscosity of 895 cp. Results The mean duration of pharyngeal transit, pharyngeal clearance, upper esophageal sphincter opening, hyoid movement and oral-pharyngeal transit were longer in the younger group compared with the older group. The relation between pharyngeal clearance duration and hyoid movement duration was similar in younger and older subjects, for 5 mL and 10 mL bolus volumes. Conclusions On average, a highly viscous liquid bolus crosses the pharynx faster in older subjects (56-77 years old than in younger subjects (19-55 years old, which suggested an adaptation to the aging process to maintain a safe swallow.

Extending R packages to support 64-bit compiled code: An illustration with spam64 and GIMMS NDVI3g data

Science.gov (United States)

Gerber, Florian; Mösinger, Kaspar; Furrer, Reinhard

2017-07-01

Software packages for spatial data often implement a hybrid approach of interpreted and compiled programming languages. The compiled parts are usually written in C, C++, or Fortran, and are efficient in terms of computational speed and memory usage. Conversely, the interpreted part serves as a convenient user-interface and calls the compiled code for computationally demanding operations. The price paid for the user friendliness of the interpreted component is-besides performance-the limited access to low level and optimized code. An example of such a restriction is the 64-bit vector support of the widely used statistical language R. On the R side, users do not need to change existing code and may not even notice the extension. On the other hand, interfacing 64-bit compiled code efficiently is challenging. Since many R packages for spatial data could benefit from 64-bit vectors, we investigate strategies to efficiently pass 64-bit vectors to compiled languages. More precisely, we show how to simply extend existing R packages using the foreign function interface to seamlessly support 64-bit vectors. This extension is shown with the sparse matrix algebra R package spam. The new capabilities are illustrated with an example of GIMMS NDVI3g data featuring a parametric modeling approach for a non-stationary covariance matrix.

Test Program for the Performance Analysis of DNS64 Servers

Directory of Open Access Journals (Sweden)

Gábor Lencse

2015-09-01

Full Text Available In our earlier research papers, bash shell scripts using the host Linux command were applied for testing the performance and stability of different DNS64 server imple­mentations. Because of their inefficiency, a small multi-threaded C/C++ program (named dns64perf was written which can directly send DNS AAAA record queries. After the introduction to the essential theoretical background about the structure of DNS messages and TCP/IP socket interface programming, the design decisions and implementation details of our DNS64 performance test program are disclosed. The efficiency of dns64perf is compared to that of the old method using bash shell scripts. The result is convincing: dns64perf can send at least 95 times more DNS AAAA record queries per second. The source code of dns64perf is published under the GNU GPLv3 license to support the work of other researchers in the field of testing the performance of DNS64 servers.

Expression of CD64 on Circulating Neutrophils Favoring Systemic Inflammatory Status in Erythema Nodosum Leprosum.

Directory of Open Access Journals (Sweden)

Veronica Schmitz

2016-08-01

Full Text Available Erythema Nodosum Leprosum (ENL is an immune reaction in leprosy that aggravates the patient´s clinical condition. ENL presents systemic symptoms of an acute infectious syndrome with high leukocytosis and intense malaise clinically similar to sepsis. The treatment of ENL patients requires immunosuppression and thus needs to be early and efficient to prevent both disabilities and permanent nerve damage. Some patients experience multiple episodes of ENL and prolonged use of immunosuppressive drugs may lead to serious adverse effects. Thalidomide treatment is extremely effective at ameliorating ENL symptoms. Several mechanisms have been proposed to explain the efficacy of thalidomide in ENL, including the inhibition of TNF production. Given its teratogenicity, thalidomide is prohibitive for women of childbearing age. A rational search for molecular targets during ENL episodes is essential to better understand the disease mechanisms involved, which may also lead to the discovery of new drugs and diagnostic tests. Previous studies have demonstrated that IFN-γ and GM-CSF, involved in the induction of CD64 expression, increase during ENL. The aim of the present study was to investigate CD64 expression during ENL and whether thalidomide treatment modulated its expression. Leprosy patients were allocated to one of five groups: (1 Lepromatous leprosy, (2 Borderline leprosy, (3 Reversal reaction, (4 ENL, and (5 ENL 7 days after thalidomide treatment. The present study demonstrated that CD64 mRNA and protein were expressed in ENL lesions and that thalidomide treatment reduced CD64 expression and neutrophil infiltrates-a hallmark of ENL. We also showed that ENL blood neutrophils exclusively expressed CD64 on the cell surface and that thalidomide diminished overall expression. Patient classification based on clinical symptoms found that severe ENL presented high levels of neutrophil CD64. Collectively, these data revealed that ENL neutrophils express CD64

Despite modern CT systems and expert evaluators, the diagnostic performance of coronary CT angiography is limited by overestimation of vessel stenosis which reduces the positive predictive value (PPV) of the test. The aim of this study was to evaluate the performance of combined cardiac PET/64-detector CT angiography. Included in this retrospective study were 33 consecutive patients (5 women, 28 men; mean age 61.6 years, range 47-87 years, mean BMI 27.3±5.2 kg/m 2 ) with clinically suspected flow-limiting coronary artery disease who underwent combined cardiac PET/64-detector CT angiography and invasive angiography. Combined PET/CT images were reported by an experienced dual-accredited radiologist/nuclear physician. An experienced cardiac CT radiologist re-read the CT images without PET. Stenotic disease was defined as >50% vessel narrowing. Invasive coronary angiography was used as a reference standard. Local ethics committee approval and patient consent were obtained. CT angiography (without PET data) was concordant with invasive angiography in 31/33 patients and at a patient level, the sensitivity in detecting significant coronary artery lesions was 100%, the specificity was 82%, the PPV was 92% and the negative predictive value (NPV) was 100%. Using combined PET/CT angiography the findings were concordant with invasive angiography in 32/33 patients and at a patient level, the sensitivity was 96%, the specificity was 100%, the PPV was 100% and the NPV was 91%. The use of integrated cardiac PET/64-detector CT angiography is feasible and appears to improve some aspects of the diagnostic performance of 64-detector coronary artery angiography in detecting coronary artery disease.

Revascularization of damaged limbs/digits is technically feasible, but indications for surgical replantation remain controversial. The authors analyzed the survival rate of upper limb amputations and the associated factors in different age groups. They grouped 371 limb/digit amputees (average age, 44 years; range, 2-85 years) treated in their hospital during the past 10 years into three groups based on age (young, ≤ 15 years, n  = 12; adult, 16-64 years, n  = 302; elderly, ≥ 65 years, n  = 57) and analyzed their injury type (extent of injury and stump status), operation method, presence of medical complications (Charlson comorbidity index), and survival rate. There were 168 replantations, and the overall replantation survival rate was 93%. The Charlson comorbidity index of the replantation patients was 0 in 124 cases; 1 in 32; 2 in 9; and 3 in 3, but it did not show any significant difference in survival rate after replantation. Eight elderly patients (14%) did not opt for replantation. Younger patients tended to undergo replantation, but they had lower success rates due to their severe injury status. The results of this study show that the survival rate of replantation in elderly patients is equal to that in adults. Stump evaluation is important for survival, but the presence of medical complications is not associated with the overall survival rate.

The Lions Eye Bank of South Australia was established six years ago and has collected corneas from 790 donors. The consent rate is currently 82% of requests made. Two-thirds of donors have been male, with mean donor age/year varying from 54 to 64 years (range two to 93 years). Cardiovascular and respiratory diseases, trauma and haemorrhage account for 80% of all donor deaths. Mean death to enucleation time is five hours. Corneas assessed as being of excellent or very good quality are released preferentially from the bank; those with central endothelial cell counts of less than 1500 cells/mm2 are discarded. Fewer than 1% of donors have returned a positive result for HIV or hepatitis B. Of the 1580 corneas collected by the bank, 863 (55%) have been used for transplantation with a primary non-function rate of 0.46%. The evolving policies, logistics of operation and methodologies employed by the bank are described in detail.

ATLAS software stack on ARM64

CERN Document Server

Smith, Joshua Wyatt; The ATLAS collaboration

2016-01-01

The ATLAS experiment explores new hardware and software platforms that, in the future, may be more suited to its data intensive workloads. One such alternative hardware platform is the ARM architecture, which is designed to be extremely power efficient and is found in most smartphones and tablets. CERN openlab recently installed a small cluster of ARM 64-bit evaluation prototype servers. Each server is based on a single-socket ARM 64-bit system on a chip, with 32 Cortex-A57 cores. In total, each server has 128 GB RAM connected with four fast memory channels. This paper reports on the port of the ATLAS software stack onto these new prototype ARM64 servers. This included building the "external" packages that the ATLAS software relies on. Patches were needed to introduce this new architecture into the build as well as patches that correct for platform specific code that caused failures on non-x86 architectures. These patches were applied such that porting to further platforms will need no or only very little adj...

The NA64 experiment, known as P348 before official approval, was proposed to the CERN SPSC on January 2014 with main goal the search for the following decay modes A′ → invisible A′ → e−e+ (1) In March 2016 P348 was granted approval by the CERN Research Board and received the title NA64. Since having been promoted, the experiment has been conducting the searches the searches for the processes mentioned above at the CERN SPS. NA64 is a fixed target experiment which utilizes the active beam dump. The detection of rare processes is based on the missing energy techniques. Such techniques are used for particles whose interaction with the detector is very small, so that they escape the detection and carry away some energy. A significant missing energy in the experiment means that such particles are produced. The method of the search for the A′ → invisible decay is as follows. If the A′ exists it could be produced via the kinetic mixing with bremsstrahlung photons in the reaction of high-energy elec...

Development of esophageal squamous cell carcinoma (ESCC) involves alterations in multiple genes with corresponding proteins. Recent studies have demonstrated that centrosomal protein 55 (CEP55) shares certain features with oncogenes, and CEP55 overexpression is associated with the development and progression of malignant tumors. The present study aimed to analyze, for the first time, whether CEP55 expression is related to clinicopothalogic features in the esophageal squamous cell carcinoma (ESCC), as well as patient survival. A total of 110 patients with mid-thoracic ESCC who suffered from Ivor-Lewis were enrolled. The CEP55 expression profile of these patients in tumour tissues and corresponding healthy esophageal mucosa (CHEM) was detected by immunohistochemistry and semi-quantitative reverse transcription-polymerase chain reaction analyses. Correlations between CEP55 expression and clinicopathological factors were analyzed using χ 2 test. The log-rank test was employed to calculate survival rate. A Cox regression multivariate analysis was performed to determine independent prognostic factors. The results demonstrated that CEP55 expression in ESCC was significantly higher than that of CHEM (POverexpression of CEP55 was significantly associated with differentiation degree (P=0.022), T stage (P=0.019), lymph node metastasis (P=0.033), clinicopathological staging (P=0.002) and tumor recurrence (P=0.021) in locally advanced ESCC patients. In addition, CEP55 overexpression was significantly associated with reduced overall survival of patients after surgery (P=0.012). The 5-year survival rate of patients without CEP55 overexpression was significantly higher than that of patients with CEP55 overexpression (P=0.012). Therefore, these findings suggest that CEP55 overexpression correlates with poor prognosis in locally advanced ESCC patients.

The hypoxia PET tracer (64)Cu-diacetyl-bis(N(4)-methylthiosemicarbazonate) ((64)Cu-ATSM) has shown promising results in clinical studies. However, concerns have been raised with regard to the possible effect of copper metabolism and free copper on tumor uptake and thereby the robustness of (64)Cu-ATSM as a hypoxia marker. In this study, accumulation and distribution of (64)Cu-ATSM and (64)CuCl2 in tumor tissue were compared with partial pressure of oxygen (pO2) probe measurements. One-hour dynamic PET scans were performed on nude mice bearing subcutaneous human head and neck tumors (FaDu) and human colorectal tumors (HT29) after administration of either (64)Cu-ATSM or (64)CuCl2. Subsequently, tracks were generated and track markers were positioned in tumors to allow for registration of their exact location on the high-resolution CT scan. After completion of the CT scan, pO2 probe measurements were performed along each track. PET and CT images were coregistered and ROIs drawn on the basis of the location of track markers and pO2 probe measurement depth. A linear mixed model for repeated measures was applied for the comparison of PET tracer uptake to corresponding pO2 values. Comparable uptake of (64)Cu-ATSM and (64)CuCl2 was found in the kidney, muscle, and liver of all animals, but (64)CuCl2 showed a higher uptake 10-60 min after injection in both tumor models. Significant differences were also found for both tumor-to-muscle and tumor-to-liver ratios. The intratumoral distribution of (64)Cu-ATSM, but not (64)CuCl2, showed a significant negative relationship with pO2 measurements in FaDu tumors. However, this relationship was not found in HT29 tumors. (64)Cu-ATSM and (64)CuCl2 displayed different uptake in tumors. In human head and neck xenografts, (64)Cu-ATSM but not (64)CuCl2 reflected pO2 measurements, indicating that (64)Cu-ATSM is a hypoxia-specific marker in this tumor type. However, data from colorectal cancer xenografts indicated that (64)Cu-ATSM may not be

Full Text Available Introduction: A disproportionate number of individuals with human immunodeficiency virus (HIV have mental health and substance-use disorders (MHSUDs, and MHSUDs are significantly associated with their emergency department (ED visits. With an increasing share of older adults among HIV patients, this study investigated the associations of MHSUDs with ED outcomes of HIV patients in four age groups: 21-34, 35-49, 50-64, and 65+ years. Methods: We used the 2012 Nationwide Emergency Department Sample (NEDS dataset (unweighted n=23,244,819 ED events by patients aged 21+, including 115,656 visits by patients with HIV. Multinomial and binary logistic regression analyses, with “treat-and-release” as the base outcome, were used to examine associations between ED outcomes and MHSUDs among visits that included a HIV diagnosis in each age group. Results: Mood and “other” mental disorders had small effects on ED-to-hospital admissions, as opposed to treat-and-release, in age groups younger than 65+ years, while suicide attempts had medium effects (RRR=3.56, CI [2.69-4.70]; RRR=4.44, CI [3.72-5.30]; and RRR=5.64, CI [4.38- 7.26] in the 21-34, 35-49, and 50-64 age groups, respectively. Cognitive disorders had mediumto-large effects on hospital admissions in all age groups and large effects on death in the 35-49 (RRR=7.29, CI [3.90-13.62] and 50-64 (RRR=5.38, CI [3.39-8.55] age groups. Alcohol use disorders (AUDs had small effects on hospital admission in all age groups (RRR=2.35, 95% CI [1.92-2.87]; RRR=2.15, 95% CI [1.95-2.37]; RRR=1.92, 95% CI [1.73-2.12]; and OR=1.93, 95% CI [1.20-3.10] in the 21-34, 35-49, 50-64, and 65+ age groups, respectively. Drug use disorders (DUDs had small-to-medium effects on hospital admission (RRR=4.40, 95% CI [3.87-5.0]; RRR=4.07, 95% CI [3.77-4.40]; RRR=4.17, 95% CI [3.83-4.55]; and OR=2.53, 95% CI [2.70- 3.78] in the 21-34, 35-49, 50-64, and 65+ age groups, respectively. AUDs and DUDs were also significantly related to

Age is integrated in most risk stratification systems for well-differentiated thyroid cancer (WDTC). The most appropriate age threshold for stage grouping of WDTC is debatable. The objective of this study was to evaluate the best age threshold for stage grouping by comparing multivariable models designed to evaluate the independent impact of various prognostic factors, including age based stage grouping, on the disease specific survival (DSS) of our population-based cohort. Data from population-based thyroid cancer cohort of 2125 consecutive WDTC, diagnosed during 1970-2010, with a median follow-up of 11.5 years, was used to calculate DSS using the Kaplan Meier method. Multivariable analysis with Cox proportional hazard model was used to assess independent impact of different prognostic factors on DSS. The Akaike information criterion (AIC), a measure of statistical model fit, was used to identify the most appropriate age threshold model. Delta AIC, Akaike weight, and evidence ratios were calculated to compare the relative strength of different models. The mean age of the patients was 47.3 years. DSS of the cohort was 95.6% and 92.8% at 10 and 20 years respectively. A threshold of 55 years, with the lowest AIC, was identified as the best model. Akaike weight indicated an 85% chance that this age threshold is the best among the compared models, and is 16.8 times more likely to be the best model as compared to a threshold of 45 years. The age threshold of 55 years was found to be the best for TNM stage grouping. Copyright © 2015 Elsevier Ltd. All rights reserved.

Blood viscosity is elevated in hypertensive subjects, but the association of viscosity with arterial blood pressure in the general population, and the influence of social, lifestyle and disease characteristics on this association, are not established. In the Edinburgh Artery Study, 1592 men and women aged 55-74 years selected randomly from the general population attended a university clinic. A fasting blood sample was taken for the measurement of blood viscosity and its major determinants (haematocrit, plasma viscosity and fibrinogen). Systolic pressure was related univariately to blood viscosity (P viscosity (P index. Diastolic pressure was related univariately to blood viscosity (P viscosity (P viscosity and systolic pressure was confined to males. Blood viscosity was associated equally with systolic and diastolic pressures in males, and remained independently related on multivariate analysis adjusting for age, sex, body mass index, social class, smoking, alcohol intake, exercise, angina, HDL and non-HDL cholesterol, diabetes mellitus, plasma viscosity, fibrinogen, and haematocrit.

Conclusion: IL women are more fit than institutionalized DC elderly women. The multimodal training was effective in improving all FF components related to daily living activities, in all age groups

Pituitary stalk interruption syndrome in Chinese people: clinical characteristic analysis of 55 cases.

Directory of Open Access Journals (Sweden)

Qinghua Guo

Full Text Available OBJECTIVE: Pituitary stalk interruption syndrome (PSIS is characterized by the absence of pituitary stalk, pituitary hypoplasia, and ectopic posterior pituitary. Due to the rarity of PSIS, clinical data are limited, especially in Chinese people. Herein, we analyzed the clinical characteristics of patients diagnosed with PSIS from our center over 10 years. PATIENTS AND METHODS: We retrospectively analyzed the clinical manifestations and laboratory and MRI findings in 55 patients with PSIS. RESULTS: Of the 55 patients with PSIS, 48 (87.3% were male. The average age was 19.7±6.7 years and there was no familial case. A history of breech delivery was documented in 40 of 45 patients (88.9% and 19 of 55 patients (34.5% had a history of dystocia. Short stature was found in 47 of 55 patients (85.5% and bone age delayed 7.26±5.37 years. Secondary sex characteristics were poor or undeveloped in most patients. The prevalence of deficiencies in growth hormone, gonadotropins, corticotropin, and thyrotropin were 100%, 95.8%, 81.8%, 76.3%, respectively. Hyperprolactinemia was found in 36.4% of patients. Three or more pituitary hormone deficiencies were found in 92.7% of the patients. All patients had normal posterior pituitary function and absent pituitary stalk on imaging. The average height of anterior pituitary was 28 mm, documented anterior pituitary hypoplasia. Midline abnormalities were presented in 9.1% of patients. CONCLUSIONS: The clinical features of our Chinese PSIS patients seem to be different from other reported patients in regarding to the higher degree of hypopituitarism and lower prevalence of midline defects. In addition, our patients were older at the time of case detection and the bone age was markedly delayed. We also had no cases of familial PSIS.

The radiation exposure of four different 64-slice MDCT-colonography (CTC) protocols was evaluated using an Alderson-Rando phantom. Protocols using 30 mAs (collimation 20 x 1.2mm), 50 mAs (collimation 20 x 1.2 and 64 x 0.6mm) and 80 mAs (20 x 1.2 mm) representing screening low-dose, routine, narrow collimation and oncologic staging setups were measured with an Alderson-Rando phantom (Alderson Research Laboratories Inc.). Scans were performed on a 64-row MDCT (SOMATOM Sensation 64, Siemens) simulating the prone and supine positions with a constant voltage of 120 kV. Dose values (male/female) were 2.5/2.9, 3.8/4.2, 4.2/4.5 and 5.7/6.4 mSv for 30, 50 (20 x 1.2 and 64 x 0.6 mm) and 80 mAs, respectively. Measurements showed an elevated dose for females (11.5% mean; compared to males). Use of narrow collimation combined with 50 mAs resulted in a small increase of dose exposure of 10.5 (male) and 7.1% (female). Gonad doses ranged from 0.9 to 2.6 mSv (male) and from 1.5 to 3.5 mSv (female). In all protocols, the stomach wall, lower colon, urinary bladder and liver were slightly more highly exposed (all <2.3 mSv) than the other organs, and the breast dose was <0.3 mSv in every setup. Values of radiation exposure in 64- and 16-slice CTC differ only marginally when using the narrow collimation. In 64-slice CTC, the use of narrow (64 x 0.6 mm) collimation shows slightly elevated dose values compared to wider (20 x 1.2 mm) collimation. (orig.)

Dose values (male/female) were 2.5/2.9, 3.8/4.2, 4.2/4.5 and 5.7/6.4 mSv for 30, 50 (20 x 1.2 and 64 x 0.6 mm) and 80 mAs, respectively. Measurements showed an elevated dose for females (11.5% mean; compared to males). Use of narrow collimation combined with 50 mAs resulted in a small increase of dose exposure of 10.5 (male) and 7.1% (female). Gonad doses ranged from 0.9 to 2.6 mSv (male) and from 1.5 to 3.5 mSv (female). In all protocols, the stomach wall, lower colon, urinary bladder and liver were slightly more highly exposed (all <2.3 mSv) than the other organs, and the breast dose was <0.3 mSv in every setup. Values of radiation exposure in 64- and 16-slice CTC differ only marginally when using the narrow collimation. In 64-slice CTC, the use of narrow (64 x 0.6 mm) collimation shows slightly elevated dose values compared to wider (20 x 1.2 mm) collimation. (orig.)

To provide an update on trends in asthma mortality in Brazil for two age groups: 0-4 years and 5-34 years. Data on mortality from asthma, as defined in the International Classification of Diseases, were obtained for the 1980-2014 period from the Mortality Database maintained by the Information Technology Department of the Brazilian Unified Health Care System. To analyze time trends in standardized asthma mortality rates, we conducted an ecological time-series study, using regression models for the 0- to 4-year and 5- to 34-year age groups. There was a linear trend toward a decrease in asthma mortality in both age groups, whereas there was a third-order polynomial fit in the general population. Although asthma mortality showed a consistent, linear decrease in individuals ≤ 34 years of age, the rate of decline was greater in the 0- to 4-year age group. The 5- to 34-year group also showed a linear decline in mortality, and the rate of that decline increased after the year 2004, when treatment with inhaled corticosteroids became more widely available. The linear decrease in asthma mortality found in both age groups contrasts with the nonlinear trend observed in the general population of Brazil. The introduction of inhaled corticosteroid use through public policies to control asthma coincided with a significant decrease in asthma mortality rates in both subsets of individuals over 5 years of age. The causes of this decline in asthma-related mortality in younger age groups continue to constitute a matter of debate.
