[Epidemics and diseases during the Independence period in Mexico].

Viesca-Treviño, Carlos

2010-01-01

The epidemics and endemic diseases in Mexico were not a problem before the Independence period. Hunger was less than in the past. The 1806 Influenza epidemics had been forgotten. Measles was considered a benign illness. In 1810, there was an increase in the number of cases of black vomit in Veracruz. Sixty percent of 541 hospitalized patients die of the disease. In 1812, an outbreak of yellow fever spread from Veracruz to Jalapa accompanying the movement of troops and killing over 300 soldiers of the Castilla's Battalion. The appearance of petechial fever, maybe typhus marketed in 1813 the onset of the most important epidemics. The preceding was the indirect effect of war: diseases of prisons and military quarters which became overwhelming in times where the movements of troops and of important groups of populations along with crowing, loss homes, hunger and bad hygiene habits. There was also Influenza or "pestilent cold." Measures of detection and quarantine were taken. "Naranjate" mixed with tartaric cremor was used against fever. Fumigation with nitric acid and burners, where they incinerated gun powder were among the health protection policies. It is noteworthy the advance and relief provided by the introduction of smallpox vaccine, the only preventive mean useful against smallpox which was a breakthrough in public health.

Women spacefarers sixty different paths to space

CERN Document Server

Cavallaro, Umberto

2017-01-01

This book tells the fascinating stories of the valiant women who broke down barriers to join the space program. Beginning with the orbital flight of USSR cosmonaut Valentina Tereshkova in 1963, they became players in the greatest adventure of our time. The author contextualizes their accomplishments in light of the political and cultural climate, from the Cold War in the background to the changing status of women in society at large, during the Seventies. The book includes the biographies of, and in some cases interviews with, the sixty women who flew in space in the first half century of space history. It reports their achievements and some little known details. The result is a gallery of pioneering women who reached for the stars: women who, with exceptional skill, hard work, and dedication, reached impressive careers as accomplished pilots, researchers, and engineers; many are now in high level managerial positions both at NASA or in public and private organizations, and all left a legacy of strength.

Full Text Available The aim of this study was to investigate the influence of energy status of cows, estimated by body condition score, on the incidence and the degree of hepatic lipidosis during the early stage of lactation. Cows were divided into four groups: dry, early puerperal, early lactation and late lactation period. Each group consisted of 60 cows. Body condition was scored by the method established in Elaco Animal Health Buletin Al 8478. According to this method, body condition score is represented numerically from 1 to 5 points. Liver samples for pathohistological analyses were taken by biopsy from early lactation cows (60. day of lactation. Fat content in hepatocytes was determined morphometrically and results were compared with criteria based on total lipid and triglyceride content in liver tissue. On farm A, average body condition scores were in a range from 3.31, at sixty days of lactation, to 3.86 points in the dry period. Nevertheless, the range was wider on farm B, and was from 2.18 points at sixty days of lactation to 4.15 points at the dry period. Besides, differences in average body condition scores were higher than 1 point, and in some cases (between late lactation or dry period to sixty days of lactation were almost 2 points. The incidence and the degree of hepatic lipidosis strongly differ between the two examined farms. On farm A the incidence of hepatic lipidosis was 18.33 percent, while on farm B that percent was much higher (43.32. A significant difference was established in the degree of hepatic lipidosis between those two farms. On farm A diffuse hepatic lipidosis was determined in 5.0 percent of cows, while on farm B that percent was 18.33. According to these results, most of the cows on farm B had uncontrolled lipomobilisation and severe fatty liver during the early lactation period, probably due to the obesity of these cows in late lactation and the dry period.

Determination of percent calcium carbonate in calcium chromate

The precision, accuracy and reliability of the macro-combustion method is superior to the Knorr alkalimetric method, and it is faster. It also significantly reduces the calcium chromate waste accrual problem. The macro-combustion method has been adopted as the official method for determination of percent calcium carbonate in thermal battery grade anhydrous calcium chromate and percent calcium carbonate in quicklime used in the production of calcium chromate. The apparatus and procedure can be used to measure the percent carbonate in inorganic materials other than calcium chromate. With simple modifications in the basic apparatus and procedure, the percent carbon and hydrogen can be measured in many organic material, including polymers and polymeric formulations. 5 figures, 5 tables

Travel, Politics and the Limits of Liminality During Australia’s Sixties

Directory of Open Access Journals (Sweden)

Jon Piccini

2012-10-01

Full Text Available Victor Turner describes the individual experience of travel as ‘liminal’. Opening new vistas of possibility, it upturns ordinary social conventions and codes, constructing in their place new communities of hope and change. Such utopian moments of encounter are, however, just that—moments that are fleeting and generally inconsequential. This paper seeks to understand and critique Turner’s ideas of liminality, pilgrimage and communitas within the context of Australian social movements in the ‘long’ and ‘global’ 1960s. Though often ignored or marginalised in local and international scholarship, Australia had a much more complex and interesting experience of this period than the paucity of scholarly work would indicate. In fact, a variety of activists in areas ranging from Indigenous rights to the peace and workers movements pushed the boundaries of political discourse during a period marked by stultifying social and cultural climates. Through a focus on three travel narratives—those of Brisbane radical Brian Laver and young Communist Party of Australia (CPA members to Czechoslovakia and Bulgaria during 1968, Sydney Trotskyite Denis Freney to Algeria in the early 1960s and five Indigenous activists to a Black Power conference in Atlanta, Georgia in 1970—this paper will highlight the importance of global connections to Australian social movements. The notion of liminality will initially be critiqued through a focus on pre-histories to travel: the ideas, rumours and local problems that can be glossed over in work heralding the power of the moment. Such moments of encounter were, however, still transformative for these activists, with their variety of experiences facilitating what Turner called communitas, spontaneous affinities and solidarities across borders of race, culture and understanding. The pilgrims’ return concludes this discussion, with their ‘translation’ of global ideas into new, local contexts giving them the

Abelha, Fernando José; Botelho, Miguela; Fernandes, Vera; Barros, Henrique

2010-01-01

Cardiovascular complications in the postoperative period are associated with high mortality and morbidity. Few studies have assessed the degree of dependence in these patients and their perception of health. The objective of this study was to assess the mortality and the quality of life in patients who developed major cardiac events (MCE) in the postoperative period. Retrospective study carried out in a Surgical Intensive Care Unit (SICU), between March 2006 and March 2008. The patients were assessed regarding the occurrence of CE. Six months after the hospital discharge, the Short-Form-36 (SF-36) questionnaire was filled out and dependence was assessed in relation to activities of daily living (ADL). The comparisons between independent groups of patients were carried out using Student's t test. The comparison between each variable and the occurrence of CE was carried out by logistic regression and included all patients. Of the 1,280 patients that met the inclusion criteria, 26 (2%) developed MCE. The univariate analysis identified as independent determinants for the development of major cardiac events: ASA physical status, hypertension, ischemic heart disease, congestive heart disease and score of the Revised Cardiac Risk Index (RCRI). The six-month mortality after the SICU discharge was 35%. Of the 17 surviving patients, 13 completed the questionnaires. Thirty-one percent of them reported that their general health was better on the day they answered the questionnaire, when compared to 12 months before. Sixty-nine percent of the patients were dependent in instrumental ADL e 15% in personal ADL. The development of MCE has a significant impact on the duration of hospital stay and mortality rates. Six months after the discharge from the SICU, more than 50% of the patients were dependent in at least one instrumental ADL. Copyright 2010 Elsevier Editora Ltda. All rights reserved.

Cultural change in Argentina during the sixties. An analysis of the daily newspaper La Nación

Directory of Open Access Journals (Sweden)

Belén Agostini

2015-06-01

Full Text Available In this paper we present a study of the process of cultural and social change developed in Argentina during the sixties, focusing on the appeal that authoritarianism might have had on society. Our hypothesis is that among middle classes, such appeal could have been lower than suggested in other research. From the analysis of “Columnas de la juventud” (youth columns, published by the daily newspaper La Nación –since 1965 to 1973-, we suggest that certain cultural transformations promoted by young people, were produced in a relatively short period of time –ten years-. During that interval, the representations that La Nación offered of such transformations turned from annoyance to fascination. This fact suggests that the acceptance of change in the standards of behaviour was very extended. The idea of an authoritarian society does not enable us to understand this process.

1976-01-01

Light curves of the 104 s periodicity in the transient X-ray source in Taurus (A0535+26) are presented for six energy intervals in the range 1-35 keV for the period 1975 May 30-June 2. The pulse structure ranges from an apparently simple modulation at higher energies to a very complex pattern at lower energies. No Doppler shift is observed in the 104 s pulse period during the three days of observations. This places severe constraints upon possible binary orbital motion. Upper limits on the power at other periodicities are approximately-less-than10 percent for 2 ms-2s and approximately-less-than2 percent for 2 s-2000 s

Unravelling the Mystery of the Atomic Nucleus A Sixty Year Journey 1896 — 1956

CERN Document Server

Fernandez, Bernard

2013-01-01

Unravelling the Mystery of the Atomic Nucleus tells the story of how, in the span of barely sixty years, we made a transition from the belief that matter was composed of indivisible atoms, to the discovery that in the heart of each atom lies a nucleus which is ten thousand times smaller than the atom, which nonetheless carries almost all its mass, and the transformations of which involve energies that could never be reached by chemical reactions. It was not a smooth transition. The nature of nuclei, their properties, the physical laws which govern their behaviour, and the possibility of controlling to some extent their transformations, were discovered in discontinuous steps, following paths which occasionally led to errors which in turn were corrected by further experimental discoveries. The story begins in 1896 when radioactivity was unexpectedly discovered and continues up to the nineteen-sixties. The authors describe the spectacular progress made by physics during that time, which not only revealed a new f...

2000-01-01

Purpose: To examine changes in the reference segment luminal diameter after coronary angioplasty.Methods: Sixty-one patients with stable angina pectoris or old myocardial infarction were examined. Coronary angiograms were recorded before coronary angioplasty (pre-angioplasty) and immediately after (post-angioplasty), as well as 3 months after. Artery diameters were measured on cine-film using quantitative coronary angiographic analysis.Results: The diameters of the proximal segment not involved in the balloon inflation and segments in the other artery did not change significantly after angioplasty, but the reference segment diameter significantly decreased (4.7%). More than 10% luminal reduction was observed in seven patients (11%) and more than 5% reduction was observed in 25 patients (41%). More than 5% underestimation of the stenosis was observed in 22 patients (36%) when the post-angioplasty reference diameter was used as the reference diameter, compared with when the pre-angioplasty measurement was used and more than 10% underestimation was observed in five patients (8%).Conclusion: This study indicated that evaluation by percent diameter stenosis, with the reference diameter from immediately after angioplasty, overestimates the dilative effects of coronary angioplasty, and that it is thus better to evaluate the efficacy of angioplasty using the absolute diameter in addition to percent luminal stenosis

Thirty or sixty percent milk replacer reduction for calves: effects on alfalfa hay intake and digestibility, digestive kinetics and ruminal fermentation.

Science.gov (United States)

Broesder, J T; Judkins, M B; Krysl, L J; Gunter, S A; Barton, R K

1990-09-01

Twelve artificially reared, male Holstein calves, ruminally cannulated at 53 d of age, were used in a split-plot design to study the effects of no milk replacer reduction (CON), or reduction by 30% (30R) or 60% (60R) of this value on alfalfa hay intake and digestibility, ruminal fermentation and digestive kinetics. Milk replacer reduction began at 53 d of age and continued until 135 d of age, after which no milk replacer was fed. All calves had ad libitum access to long-stemmed alfalfa hay from birth. Five collection periods were conducted at average calf ages of 72, 87, 108, 129 and 151 d. Reducing the amount of milk replacer fed resulted in a linear increase (P less than .05) in forage OM intake; however, total OM intake (forage + milk) was not different (P greater than .10) among milk reduction groups. Size of particles in feces exhibited quadratic effects in response to milk replacer reduction (P less than .05) but only in the small (less than 150 microns) size groupings. Ruminal pH and ammonia and individual VFA concentrations (except isobutyrate) were not altered by milk reduction (P greater than .10) but increased (P less than .01) with calf age. Milk replacer reduction had a quadratic effect (P less than .05) on fluid outflow rate from the rumen, increasing as milk replacer was reduced. Other fluid and particulate kinetic data, as well as NDF digestion rate and DM digestion showed no effects (P greater than .10) from milk replacer reduction but changed with calf age. Milk replacer reduction increased forage intake but had minimal effects on digestive variables evaluated, suggesting that intake of milk replacer by calves can be reduced by up to 60% without disturbing forage fermentation and passage.

Evolutionary dynamics of incubation periods.

Science.gov (United States)

Ottino-Loffler, Bertrand; Scott, Jacob G; Strogatz, Steven H

2017-12-21

The incubation period for typhoid, polio, measles, leukemia and many other diseases follows a right-skewed, approximately lognormal distribution. Although this pattern was discovered more than sixty years ago, it remains an open question to explain its ubiquity. Here, we propose an explanation based on evolutionary dynamics on graphs. For simple models of a mutant or pathogen invading a network-structured population of healthy cells, we show that skewed distributions of incubation periods emerge for a wide range of assumptions about invader fitness, competition dynamics, and network structure. The skewness stems from stochastic mechanisms associated with two classic problems in probability theory: the coupon collector and the random walk. Unlike previous explanations that rely crucially on heterogeneity, our results hold even for homogeneous populations. Thus, we predict that two equally healthy individuals subjected to equal doses of equally pathogenic agents may, by chance alone, show remarkably different time courses of disease.

Three Hundred Sixty Degree Feedback systems, while popular in business, have been less commonly implemented in local public health agencies. At the same time, they are effective methods of improving employee morale, work performance, organizational culture, and attainment of desired organizational outcomes. These systems can be purchased "off-the-shelf," or custom applications can be developed for a better fit with unique organizational needs. We describe the City of Milwaukee Health Department's successful experience customizing and implementing a 360-degree feedback system in the context of its ongoing total quality improvement efforts.

Carotid bifurcation calcium and correlation with percent stenosis of the internal carotid artery on CT angiography

International Nuclear Information System (INIS)

McKinney, Alexander M.; Casey, Sean O.; Teksam, Mehmet; Truwit, Charles L.; Kieffer, Stephen; Lucato, Leandro T.; Smith, Maurice

2005-01-01

The aim of this paper was to determine the correlation between calcium burden (expressed as a volume) and extent of stenosis of the origin of the internal carotid artery (ICA) by CT angiography (CTA). Previous studies have shown that calcification in the coronary arteries correlates with significant vessel stenosis, and severe calcification (measured by CT) in the carotid siphon correlates with significant (greater than 50% stenosis) as determined angiographically. Sixty-one patients (age range 50-85 years) underwent CT of the neck with intravenous administration of iodinated contrast for a variety of conditions. Images were obtained with a helical multidetector array CT scanner and reviewed on a three-dimensional workstation. A single observer manipulated window and level to segment calcified plaque from vascular enhancement in order to quantify vascular calcium volume (cc) in the region of the bifurcation of the common carotid artery/ICA origin, and to measure the extent of ICA stenosis near the origin. A total of 117 common carotid artery bifurcations were reviewed. A ''significant'' stenosis was defined arbitrarily as >40% (to detect lesions before they become hemodynamically significant) of luminal diameter on CTA using NASCET-like criteria. All ''significant'' stenoses (21 out of 117 carotid bifurcations) had measurable calcium. We found a relatively strong correlation between percent stenosis and the calcium volume (Pearson's r= 0.65, P<0.0001). We also found that there was an even stronger correlation between the square root of the calcium volume and the percent stenosis as measured by CTA (r= 0.77, P<0.0001). Calcium volumes of 0.01, 0.03, 0.06, 0.09 and 0.12 cc were used as thresholds to evaluate for a ''significant'' stenosis. A receiver operating characteristic (ROC) curve demonstrated that thresholds of 0.06 cc (sensitivity 88%, specificity 87%) and 0.03 cc (sensitivity 94%, specificity 76%) generated the best combinations of sensitivity and

1995-09-10

The psychosomatic care of patients after surgical treatment must comprise the analysis of quality of life with colostomy. Five different parameters were assessed of 100 colostomy patients. Sixty-one percent of our patients had skin irritation problems. Twenty-eight patients applied regular irrigation. Seventy-two percent of these had daily motions, 20% had bidaily, the remaining 8% had irregular bowel movements. Seventeen percent of the nonirrigating patients observed very irritating fecal discharge around the stoma. Embarrassing noises concomittant with bowel movements were observed by 42% and 45% struggled with bad odors. Irrigating patients had hardly any of these problems. For 65% of the patients the idea of having a colostoma meant the greatest psychological burden before the operation. The stress situation culminated in the immediate postoperative period in 10%. Forty percent of those asked were seriously worried about the reaction of their social environment. In 65% a significant decrease of social relations could be observed. Sixteen percent reported an increased social activity after colostomy had been performed. Sixty percent admitted considering the option of suicide at least once. Thirty-five percent revealed to have any kind of sexual problems after colostomy. Eight of our 100 colostomy patients experienced serious adverse reactions from their family members. In eighty percent of the cases family members showed great sympathy although they acted naively. The quality of life of colostomy patients may be best taken care of by qualified stomatherapists, out-patient proctology departments and the ileo-colostomy movement (ILCO).

A molybdenum liner sleeve and support components isolate the fueled iridium clad from the T-111 strength member. This strength member serves as the pressure vessel and fulfills the impact and hydrostatic strength requirements. The shell is manufactured from Hastelloy S which prevents the internal components from being oxidized. Conventional drawing operations were used to simplify processing and utilize existing equipment. The deep drawing reqirements for the molybdenum, T-111, and Hastelloy S were developed from past heat source hardware fabrication experiences. This resulted in multiple step drawing processes with intermediate heat treatments between forming steps. The molybdenum processing included warm forming operations. This paper describes the fabrication of these components and the multiple draw tooling developed to produce hardware to the desired specifications. copyright 1995 American Institute of Physics

Lustgarten, MS, Price, LL, Phillips, EM, Kirn, DR, Mills, J, and Fielding, RA. Serum predictors of percent lean mass in young adults. J Strength Cond Res 30(8): 2194-2201, 2016-Elevated lean (skeletal muscle) mass is associated with increased muscle strength and anaerobic exercise performance, whereas low levels of lean mass are associated with insulin resistance and sarcopenia. Therefore, studies aimed at obtaining an improved understanding of mechanisms related to the quantity of lean mass are of interest. Percent lean mass (total lean mass/body weight × 100) in 77 young subjects (18-35 years) was measured with dual-energy x-ray absorptiometry. Twenty analytes and 296 metabolites were evaluated with the use of the standard chemistry screen and mass spectrometry-based metabolomic profiling, respectively. Sex-adjusted multivariable linear regression was used to determine serum analytes and metabolites significantly (p ≤ 0.05 and q ≤ 0.30) associated with the percent lean mass. Two enzymes (alkaline phosphatase and serum glutamate oxaloacetate aminotransferase) and 29 metabolites were found to be significantly associated with the percent lean mass, including metabolites related to microbial metabolism, uremia, inflammation, oxidative stress, branched-chain amino acid metabolism, insulin sensitivity, glycerolipid metabolism, and xenobiotics. Use of sex-adjusted stepwise regression to obtain a final covariate predictor model identified the combination of 5 analytes and metabolites as overall predictors of the percent lean mass (model R = 82.5%). Collectively, these data suggest that a complex interplay of various metabolic processes underlies the maintenance of lean mass in young healthy adults.

Wake up call: Sixty ways to combat WMD

International Nuclear Information System (INIS)

Waengborg, M.

2006-01-01

Chaired by former IAEA Director General Hans Blix, the Weapons of Mass Destruction Commission attempts to tackle the seeming paradox that the key category of weapons of mass destruction-the roughly 27,000 nuclear weapons-in the hands of the established major powers are generally regarded as a legitimate source of military strength and political prestige and largely a stabilizing force, while in the hands of others are seen as an existential threat to the international community. The 14-member Weapons of Mass Destruction Commission advances the opposite perspective. Contrary to the currently fashionable rhetoric about rogue States, it takes the view that weapons of mass destruction are inherently dangerous, irrespective of whose hands they are in. Echoing the 1996 Report of the Canberra Commission on the Elimination of Nuclear Weapons, the WMDC affirms that 'so long as any State has such weapons-especially nuclear arms-others will want them. So long as any such weapons remain in any State's arsenal, there is a risk that they will one day be used, by design or accident. Any such use would be catastrophic'. This is the basic credo of the independent Weapons of Mass Destruction Commission. A recent report, issued by the WMD Commission, outlines sixty proposals on how the world could be freed of nuclear, biological and chemical weapons

Future galaxy surveys require one percent precision in the theoretical knowledge of the power spectrum over a large range including very nonlinear scales. While this level of accuracy is easily obtained in the linear regime with perturbation theory, it represents a serious challenge for small scales where numerical simulations are required. In this paper we quantify the precision of present-day N -body methods, identifying main potential error sources from the set-up of initial conditions to the measurement of the final power spectrum. We directly compare three widely used N -body codes, Ramses, Pkdgrav3, and Gadget3 which represent three main discretisation techniques: the particle-mesh method, the tree method, and a hybrid combination of the two. For standard run parameters, the codes agree to within one percent at k ≤1 h Mpc −1 and to within three percent at k ≤10 h Mpc −1 . We also consider the bispectrum and show that the reduced bispectra agree at the sub-percent level for k ≤ 2 h Mpc −1 . In a second step, we quantify potential errors due to initial conditions, box size, and resolution using an extended suite of simulations performed with our fastest code Pkdgrav3. We demonstrate that the simulation box size should not be smaller than L =0.5 h −1 Gpc to avoid systematic finite-volume effects (while much larger boxes are required to beat down the statistical sample variance). Furthermore, a maximum particle mass of M p =10 9 h −1 M ⊙ is required to conservatively obtain one percent precision of the matter power spectrum. As a consequence, numerical simulations covering large survey volumes of upcoming missions such as DES, LSST, and Euclid will need more than a trillion particles to reproduce clustering properties at the targeted accuracy.

Full Text Available Data on the activity pattern, proportion of time spent lying and the length of active and lying periods in winter are presented from a 3 year study on the Porcupine caribou herd. Animals were most active at sunrise and sunset resulting in from one (late fall, early and mid winter to two (early fall and late winter to three (spring intervening lying periods. Mean active/lying cycle length decreased from late fall (298 mm to early winter (238 min, increased to a peak in mid winter (340 min then declined in late winter (305 min and again in spring (240 min. Mean length of the lying period increased throughout the 3 winter months from 56 min m early winter to 114 min in mid winter and 153 min in late winter. The percent of the day animals spent lying decreased from fall to early winter, increased throughout the winter and declined in spring. This pattern was related, in part, to day length and was used to compare percent lying among herds. The relationship is suggested to be a means of comparing quality of winter ranges.

How I Love My 80 Percenters

Maturo, Anthony J.

2002-01-01

Don't ever take your support staff for granted. By support staff, I mean the people in personnel, logistics, and finance; the ones who can make things happen with a phone call or a signature, or by the same token frustrate you to no end by their inaction; these are people you must depend on. I've spent a lot of time thinking about how to cultivate relationships with my support staff that work to the advantage of both of us. The most important thing that have learned working with people, any people--and I will tell you how I learned this in a minute--is there are some folks you just can't motivate, so forget it, don't try; others you certainly can with a little psychology and some effort; and the best of the bunch, what I call the 80 percenters, you don't need to motivate because they're already on the team and performing beautifully. The ones you can't change are rocks. Face up to it, and just kick them out of your way. I have a reputation with the people who don't want to perform or be part of the team. They don't come near me. If someone's a rock, I pick up on it right away, and I will walk around him or her to find someone better. The ones who can be motivated I take time to nurture. I consider them my projects. A lot of times these wannabes are people who want to help but don't know how. Listen, you can work with them. Lots of people in organizations have the mindset that all that matters are the regulations. God forbid if you ever work outside those regulations. They've got one foot on that regulation and they're holding it tight like a baby holds a blanket. What you're looking for is that first sign that their minds are opening. Usually you hear it in their vocabulary. What used to sound like "We can't do that ... the regulations won't allow it ... we have never done this before," well, suddenly that changes to "We have options ... let's take a look at the options ... let me research this and get back to you." The 80 percenters you want to nurture too, but

On the basis of percent depth dose calculation, the application of - dosimetry in radiotherapy has an important role to play in reducing the chance of tumor recurrence. The aim of this study is to introduce a new formula for calculating the central axis percent depth doses of Cobalt-60 beam. Materials and Methods: In the present study, based on the British Journal of Radiology table, nine new formulas are developed and evaluated for depths of 0.5 - 30 cm and fields of (4*4) - (45*45) cm 2 . To evaluate the agreement between the formulas and the table, the average of the absolute differences between the values was used and the formula with the least average was selected as the best fitted formula. The Microsoft Excel 2000 and the Data fit 8.0 soft wares were used to perform the calculations. Results: The results of this study indicated that one amongst the nine formulas gave a better agreement with the percent depth doses listed in the table of British Journal of Radiology . The new formula has two parts in terms of log (A/P). The first part as a linear function with the depth in the range of 0.5 to 5 cm and the other one as a second order polynomial with the depth in the range of 6 to 30 cm. The average of - the differences between the tabulated and the calculated data using the formula (Δ) is equal to 0.3 152. Discussion and Conclusion: Therefore, the calculated percent depth dose data based on this formula has a better agreement with the published data for Cobalt-60 source. This formula could be used to calculate the percent depth dose for the depths and the field sizes not listed in the British Journal of Radiology table

The Egyptian garlic plants, showed higher percent of weight loss at 17 or 27 days from curing compared to those of Chinese plants. The curing period of 17 days seemed satisfactory for the Egyptian cultivar, whereas, 27 days seemed to be enough for the Chinese garlic. No significant differences were observed between common and shaded curing methods in weight loss per cent. The Chinese garlic contained higher dry matter percentage than those of the Egyptian cultivar. Shaded cured plants of the two cultivars contained higher dry matter percent than those subjected to the common curing methods. Irradiation of garlic bulbs, shaded curing method and sack packaging decreased, in general the weight loss during storage in comparison with other treatments

Leaching of cadmium, chromium, copper, lead, and zinc from two slag dumps with different environmental exposure periods under dynamic acidic condition.

Over the past few decades, zinc smelting activities in Guizhou, China have produced numerous slag dumps, which are often dispersed on roadsides and hill slopes throughout the region. During periods of acid rain, these exposed slags release heavy metals into surface water bodies. A column leaching study was designed to test the potential release of the heavy metals cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), and zinc (Zn) under simulated acid rain events. Two slags with varying environmental exposure periods were packed in columns and subjected to leaching solutions of pH 3.5, 5.5, or DI H2O at intervals of 1, 7, 14, 28, 56d. Pulse concentrations of Cd in leachate were found above 5μg/L, Cr, Pb, and Zn >10μg/L, whereas, Cu reached 10μg/L. After five leaching events, the leachability (percentage of cumulative heavy metal leached after five leaching events as in its respective total concentration in slags) of Cd was 0.05 percent and 0.035 percent from the old and young slag, respectively. Cr (0.035 percent and 0.05 percent) was greater than Cu (0.002 percent and 0.005 percent) and Zn (0.006 percent and 0.003 percent), while the lowest leachability was observed for Pb (0.0005 percent and 0.0002 percent) from the old and young slags, respectively. Reaction rates (release amount of heavy metals in certain period of leaching) of heavy metals in the leachates demonstrated the sequence of Zn>Cr>Cd, Cu>Pb. Leaching release of heavy metals was jointly affected by the pH of leaching solution and mineral composition of slags (including chemical forms of Cd, Cr, Cu, Pb, and Zn). Environmental exposure period of slags, resulting in the alteration of minerals, could affect the release process of heavy metals in leaching as well. Copyright © 2014 Elsevier Inc.

Full Text Available School meals were introduced in the Brazilian political agenda by a group of scholars known as nutrition scientists' in the 1940s. In 1955, the Campanha de Merenda Escolar, the first official school food program, was stablished, and sixty years after its inception, school food in Brazil stands as a decentralised public policy, providing services to students enrolled in public schools, which involve the Brazilian federal government, twentyseven federative units, and their 5,570 municipalities. Throughout its history, school food has gone through many stages that reflect the social transformations in Brazil: from a campaign to implement school food focused on the problem of malnutrition and the ways to solve it, to the creation of a universal public policy relying on social participation and interface between other modern, democratic, and sustainable policies, establishing a strategy for promoting food and nutrition security, development, and social protection. In this article, the School Food Program is analyzed from the perspective of four basic structures that support it as public policy: the formal structure, consisting of legal milestones that regulated the program; substantive structure, referring to the public and private social actors involved; material structure, regarding the way in which Brazil sponsors the program; and finally, the symbolic structure, consisting of knowledge, values, interests, and rules that legitimatize the policy.

To assess whether maternal HIV-positive status negatively affects family construction and the child's psychological environment. Could this be responsible for behavioral problems observed in children infected with or affected by HIV? Interviews were conducted with 60 HIV+ mothers and their infants during the perinatal period, within 3 months of delivery, collected at the time of a pediatric outpatient visit within a PMTCT program. Half of the 60 mothers did not live with the infant's father, 56% of multiparous mothers were separated from their previous children. Sixty-five percent of the fathers were informed of the mother's HIV-positive status, although 90% of fathers who lived with the mothers were informed. During pregnancy, 80% of mothers reported psychological stress; after delivery, 72% of mothers suffered from not being allowed to breastfeed their infants, 43.5% expressed a fear of transmitting the infection to the child, and 40% avoided contacts with the infant. The impact of the mother's psychological stress and anxiety related to the risk of HIV transmission through breastfeeding and casual contacts were already noticeable in the first mother-child interrelations. Although the risk of MTC transmission in now very small, psychological troubles related to maternal HIV status may negatively affect the children's well-being and behavior, psychological support should be provided for mothers and children as part of comprehensive services.

latin American literary testimony: historical foreshadowing of gender in the revolutionary discourse of the sixties

Victoria García

2015-06-01

Full Text Available The foundation of testimonio in Latin American literary field, initiated at the end of the ‘60, makes part of the institutionalization of the Cuban revolution, process where its projection to the rest of Latin America constitued a central problem. This paper studies political preconditions of testimonio. In particular, it analizes certain aspects of Cuban revolutionary discourse that anticipate features eventually developed by the literary genre, in the ways the relation between literature and politics is represented, and in the subjects of discourse that are proposed as embodiments of such relation. The paper introduces the question of Cuban revolution, as regards the exemplary status it acquired in Latin America during the sixties. Then, it examines the literary positioning represented by testimonio, as the corollary of a reflexive reconsideration operated by some Latin American writers and critics, concerning their historical role. Finally, it considers three representative documents of Cuban revolution and its continental projection: History will absolve me, by Fidel Castro, and Reminiscences of the Cuban revolutionary war and Bolivian diary, by Ernesto Guevara. We show the textual configuration of a revolutionary subject whose legitimity emerges not only from a political experience which testimony enunciates, but also from particular ways of living and representing literature in the context of a revolutionary practice. In the end of the sixties, the continental literary field would reaffirm such features as its discourse legitimating criteria, during the institutionalization of testimonio as its privileged genre.

Relationship between breast sound speed and mammographic percent density

Despite some shortcomings, mammography is currently the standard of care for breast cancer screening and diagnosis. However, breast ultrasound tomography is a rapidly developing imaging modality that has the potential to overcome the drawbacks of mammography. It is known that women with high breast densities have a greater risk of developing breast cancer. Measuring breast density is accomplished through the use of mammographic percent density, defined as the ratio of fibroglandular to total breast area. Using an ultrasound tomography (UST) prototype, we created sound speed images of the patient's breast, motivated by the fact that sound speed in a tissue is proportional to the density of the tissue. The purpose of this work is to compare the acoustic performance of the UST system with the measurement of mammographic percent density. A cohort of 251 patients was studied using both imaging modalities and the results suggest that the volume averaged breast sound speed is significantly related to mammographic percent density. The Spearman correlation coefficient was found to be 0.73 for the 175 film mammograms and 0.69 for the 76 digital mammograms obtained. Since sound speed measurements do not require ionizing radiation or physical compression, they have the potential to form the basis of a safe, more accurate surrogate marker of breast density.

Fernández González, P.; Landajo, M.; Presno, M.J.

This paper analyzes the evolution of real energy efficiency in the European Union and the attribution across countries of its percent change. Relying on a multiplicative energy intensity approach that is implemented through the Sato-Vartia Logarithmic Mean Divisia Index method, we decompose the change in aggregate energy intensity in 20 European countries for the period from 1995 to 2010. A comparative analysis of real energy intensity indices is also carried out. In addition, a new tool to monitor changes in real energy intensity in greater detail is applied. The attribution analysis of IDA (Index Decomposition Analysis) as proposed by Choi and Ang (Choi KH, Ang BW. Attribution of changes in Divisia real energy intensity index – an extension to index decomposition analysis. Energy Economics 2012;34:171–6) is used in order to assess the contribution of each individual sector to the percent change in real energy intensity. Results indicate that the European countries, particularly the former communist ones, made a remarkable effort to improve energy efficiency. Our analysis also suggests some strategies –including promotion and adaptation to more efficient techniques, innovation, improved use of technologies, R and D, and substitution for higher quality energies-, which are of particular interest to the industry sector -including construction- in ex-communist EU members, and to the industry and transport plus hotels and restaurants sectors in Western countries. - Highlights: • We apply a single and multi-period attribution analysis approach [1]. • Technical change, improved use of tech and quality energies, keys to AEI drop. • Real energy intensity shows valuable progress in former communist European members. • The biggest attribution of percent change in real energy intensity was to Industry. • Western EU: Services and Agriculture poor contributors to real energy intensity drop

The Sexual Revolution in the Sixties: A Critical Reflection on its Patriarchal Drift

2015-12-01

Full Text Available The paper undertakes a critical review from a feminist standpoint of the so called Sexual Revolution in the sixties. In first place, the contributions of significant authors such as Kate Millet and Sulamith Firestone are reconstructed. These two authors already highlighted the patriarchal and capitalist bias of the new sexual normative and stated that a 'halfway' liberation could mean women's bodies being treated even more as objects and commodities. Secondly, this article describes the hard struggle for redefining sexuality that took place after the 80's. The constitution of an anti-pornography and anti-prostitution front and its defeat by the new neoliberal view of sexuality; and it finally claims for the return to a critical approach regarding some of the present consequences of the patriarchal drift of the sexual revolution.

Adolescents with psychiatric conditions may be at risk for xerostomia. In this preliminary study, we estimated xerostomia prevalence in adolescents ages 9 to 17 years from an inpatient psychiatric clinic (N = 25) and examined whether: (1) gender and age were associated with xerostomia and (2) xerostomia was associated with self-reported cavities. We used a modified 11-item Xerostomia Index to identify xerostomia (no/yes) and asked if adolescents ever had or currently have cavities (no/yes). The mean age was 14 years (SD = 2.3) and 72% were male. Sixty percent reported xerostomia (SD = 50). There were no significant associations between xerostomia and gender (p = 0.99) or age (p = 0.66), or between xerostomia and past (p = 0.26) or current cavities (p = 0.11). Larger proportions of adolescents with xerostomia reported previous and current cavities. Sixty percent of adolescents from an inpatient psychiatric clinic reported having xerostomia, which may lead to increased caries risk over time. Additional research should examine the prevalence and consequences of xerostomia in high-risk adolescents. © 2015 Special Care Dentistry Association and Wiley Periodicals, Inc.

Clinical study on magnetic resonance imaging of lacunar infarcts and cerebrovascular high-risk group

Energy Technology Data Exchange (ETDEWEB)

Hironaka, Masatoshi (Hiroshima Univ. (Japan). School of Medicine)

1990-04-01

Magnetic resonance imaging (MRI) study was performed in 32 patients with recent lacunar stroke. T2-weighted images showed ischemic lesions more clearly than T1-weighted images. Sixty-six percent of 32 patients had periventricular lesions. Eighty-four percent had subcortical white matter lesions. Sixty-nine percent had lesions in basal ganglia. Twenty-eight percent had lesions in brainstem. Periventricular lesions were revealed symmetrically. On the other hand, lesions in other areas were not detected symmetrically. Severe periventricular lesions on MRI were similar to those of Binswanger's disease. Patients with severe periventricular lesions had often hypertension. Moreover, two of them had dementia. Twenty-three patients with transient ischemic attack had less remarkable lesions than patients with lacunar stroke. Thirty-seven patients with a history of cerebrovascular risk factors (hypertension, diabetes mellitus) had severer lesions compared with normal controls. Sixty-one percent of controls, who had no cerebrovascular symptoms and signs, had MRI lesions. These results suggest that MRI is useful for detection of cerebral ischemic lesions with no associated clinical symptoms or signs. (author).

Ailioaie, C.; Ailioaie, Laura

2000-06-01

Bronchial asthma is a common disease in both the pediatric and adult populations, characterized by wide variations over short periods of time in resistance to airflow in intrapulmonary airways. A primary goal in the use of low- level laser therapy (LLLT) was the safe, effective and rapid palliation of symptoms owing to tracheal or bronchial obstruction. We have investigated the effects of LLLT comparatively with other modality trials in children's asthma. In the study were included 98 patients aged 10-18 years diagnosed with moderate or severe asthma, in attack- free period. The patients were divided into 3 groups. Group 1 received only laser therapy using extra meridian acupuncture points and scanning technique. Group 2 was treated only with inhaled Serevent 2 X 25 micrometers , two times daily, 3 months. Group 3 was tread with Theophylline retard in dosage of 15-mg/kg/12 h, 3 months. At the end of treatment we remarked a noticeable improvement of the clinical, functional and immunological characteristics at 83 percent of patients in group 1, comparatively with only 70 percent (group 2) and 53 percent (group 3). The LLLT had a very good action on bronchial patency , displayed an immunocorrecting action and is recommended in attack-free periods at children.

Full Text Available Abstract Background This study aimed to examine the associations between psychiatric diagnoses, trauma and suicidiality in psychiatric patients at intake. Methods During two months, all consecutive patients (n = 139 in a psychiatric hospital in Western Norway were interviewed (response rate 72%. Results Ninety-one percent had been exposed to at least one trauma; 69 percent had been repeatedly exposed to trauma for longer periods of time. Only 7% acquired a PTSD diagnosis. The comorbidity of PTSD and other psychiatric diagnoses were 78%. A number of diagnoses were associated with specific traumas. Sixty-seven percent of the patients reported suicidal thoughts in the month prior to intake; thirty-one percent had attempted suicide in the preceding week. Suicidal ideation, self-harming behaviour, and suicide attempts were associated with specific traumas. Conclusion Traumatised patients appear to be under- or misdiagnosed which could have an impact on the efficiency of treatment.

Barber, A. D.; Harms, G. A.

2009-01-01

The first approach-to-critical experiment in the Seven Percent Critical Experiment series was recently completed at Sandia. This experiment is part of the Seven Percent Critical Experiment which will provide new critical and reactor physics benchmarks for fuel enrichments greater than five weight percent. The inverse multiplication method was used to determine the state of the system during the course of the experiment. Using the inverse multiplication method, it was determined that the critical experiment went slightly supercritical with 1148 fuel elements in the fuel array. The experiment is described and the results of the experiment are presented. (authors)

Valeri, C.R.; Pivacek, L.E.; Ouellet, R.; Gray, A.

1984-01-01

Studies were done to compare three methods to determine the 100 percent survival value from which to estimate the 24-hour posttransfusion survival of preserved red cells. The following methods using small aliquots of 51 Cr-labeled autologous preserved red cells were evaluated: First, the 125 I-albumin method, which is an indirect measurement of the recipient's red cell volume derived from the plasma volume measured using 125 I-labeled albumin and the total body hematocrit. Second, the body surface area method (BSA) in which the recipient's red cell volume is derived from a body surface area nomogram. Third, an extrapolation method, which extrapolates to zero time the radioactivity associated with the red cells in the recipient's circulation from 10 to 20 or 15 to 30 minutes after transfusion. The three methods gave similar results in all studies in which less than 20 percent of the transfused red cells were nonviable (24-hour posttransfusion survival values of between 80-100%), but not when more than 20 percent of the red cells were nonviable. When 21 to 35 percent of the transfused red cells were nonviable (24-hour posttransfusion survivals of 65 to 79%), values with the 125 I-albumin method and the body surface area method were about 5 percent lower (p less than 0.001) than values with the extrapolation method. When greater than 35 percent of the red cells were nonviable (24-hour posttransfusion survival values of less than 65%), values with the 125 I-albumin method and the body surface area method were about 10 percent lower (p less than 0.001) than those obtained by the extrapolation method

Awake craniotomy is currently a useful surgical approach to help identify and preserve functional areas during cortical and subcortical tumor resections. Methodologies have evolved over time to maximize patient safety and minimize morbidity using this technique. The goal of this study is to analyze a single surgeon's experience and the evolving methodology of awake language and sensorimotor mapping for glioma surgery. The authors retrospectively studied patients undergoing awake brain tumor surgery between 1986 and 2014. Operations for the initial 248 patients (1986-1997) were completed at the University of Washington, and the subsequent surgeries in 611 patients (1997-2014) were completed at the University of California, San Francisco. Perioperative risk factors and complications were assessed using the latter 611 cases. The median patient age was 42 years (range 13-84 years). Sixty percent of patients had Karnofsky Performance Status (KPS) scores of 90-100, and 40% had KPS scores less than 80. Fifty-five percent of patients underwent surgery for high-grade gliomas, 42% for low-grade gliomas, 1% for metastatic lesions, and 2% for other lesions (cortical dysplasia, encephalitis, necrosis, abscess, and hemangioma). The majority of patients were in American Society of Anesthesiologists (ASA) Class 1 or 2 (mild systemic disease); however, patients with severe systemic disease were not excluded from awake brain tumor surgery and represented 15% of study participants. Laryngeal mask airway was used in 8 patients (1%) and was most commonly used for large vascular tumors with more than 2 cm of mass effect. The most common sedation regimen was propofol plus remifentanil (54%); however, 42% of patients required an adjustment to the initial sedation regimen before skin incision due to patient intolerance. Mannitol was used in 54% of cases. Twelve percent of patients were active smokers at the time of surgery, which did not impact completion of the intraoperative mapping

Percent mammographic density adjusted for age and body mass index (BMI) is one of the strongest risk factors for breast cancer and has a heritable component that remains largely unidentified. We performed a three-stage genome-wide association study (GWAS) of percent mammographic density to identify novel genetic loci associated with this trait. In stage 1, we combined three GWASs of percent density comprised of 1241 women from studies at the Mayo Clinic and identified the top 48 loci (99 single nucleotide polymorphisms). We attempted replication of these loci in 7018 women from seven additional studies (stage 2). The meta-analysis of stage 1 and 2 data identified a novel locus, rs1265507 on 12q24, associated with percent density, adjusting for age and BMI (P = 4.43 × 10(-8)). We refined the 12q24 locus with 459 additional variants (stage 3) in a combined analysis of all three stages (n = 10 377) and confirmed that rs1265507 has the strongest association in the 12q24 region (P = 1.03 × 10(-8)). Rs1265507 is located between the genes TBX5 and TBX3, which are members of the phylogenetically conserved T-box gene family and encode transcription factors involved in developmental regulation. Understanding the mechanism underlying this association will provide insight into the genetics of breast tissue composition.

Status report on potential future nuclear energy cycles in the period 1982-2020

International Nuclear Information System (INIS)

1982-11-01

The demand for electrical power and the availability of fuel to supply it is the driving force behind any change in the electrical supply technology. A survey of a number of recent world wide electrical power growth projections indicates a growth rate of between 2 percent and 4 percent within the period of 1980 to 2020. In some countries, such as France and Japan, without large domestic supplies of conventional fuels, there is a significant effort to extend supplies of uranium using advanced fuel cycles and breeder reactors. In North America, and in particular the United States, there would appear to be adequate supplies of conventional fuel for the projected growth for the period of the study. Development of advanced fuel cycles in this case will be driven by economic considerations rather than strategic ones. A review of the current status of fusion test facilities is included in the report, but the consensus of opinion of the literature surveyed would indicate that no commercial scale generating plant will be operational within the study period

A very rare spinal cord tumor primary spinal oligodendroglioma: A review of sixty cases in the literature

Directory of Open Access Journals (Sweden)

Full Text Available Literature review. In this study, we evaluated a case of primary spinal oligodendroglioma (PSO with a rare localization between L3 and S2, and also examined sixty cases in the literature in terms of demographic characteristics, clinical, radiological, and histopathological characteristics, and treatment planning. A case of PSO has been presented, and the relevant literature between 1931 and 2016 was reviewed. A total of 57 papers regarding PSO were found and utilized in this review. The main treatment options include radical surgical excision with neuromonitoring, followed by radiotherapy. Despite these treatment protocols, the relapse rate is high, and treatment does not significantly prolong survival. Oligodendrogliomas are rare among the primary spinal cord tumors. Oligodendrogliomas are predominantly found in the cervical spinal cord, thoracic spinal cord, or junctions during childhood and adulthood. Extension to the sacral region, inferior to the Conus, is very rare. Furthermore, of the sixty cases in the literature, the case we present here is the first to be reported in this particular age group. These localizations usually occur in the pediatric age group and after relapses. While for a limited number of cases the oligodendroglioma initiates in the thoracic region and reaches as far as L2, we encountered a case of an oligodendroglioma within the range of L3 to S2. Clinical findings are observed in accordance with location, and magnetic resonance imaging is the gold standard for diagnosis.

PURPOSE To characterize the diagnostic properties of serial percent-free prostate-specific antigen (PSA) in relation to PSA in a multi-ethnic, multi-racial cohort of healthy men. MATERIALS AND METHODS 6,982 percent-free PSA and PSA measures were obtained from participants in a 12 year+ Texas screening study comprising 1625 men who never underwent biopsy, 497 who underwent one or more biopsies negative for prostate cancer, and 61 diagnosed with prostate cancer. Area underneath the receiver-operating-characteristic-curve (AUC) for percent-free PSA, and the proportion of patients with fluctuating values across multiple visits were determined according to two thresholds (under 15% versus 25%) were evaluated. The proportion of cancer cases where percent-free PSA indicated a positive test before PSA > 4 ng/mL did and the number of negative biopsies that would have been spared by percent-free PSA testing negative were computed. RESULTS Percent-free PSA fluctuated around its threshold of PSA tested positive earlier than PSA in 71.4% (34.2%) of cancer cases, and among men with multiple negative biopsies and a PSA > 4 ng/mL, percent-free PSA would have tested negative in 31.6% (65.8%) instances. CONCLUSIONS Percent-free PSA should accompany PSA testing in order to potentially spare unnecessary biopsies or detect cancer earlier. When near the threshold, both tests should be repeated due to commonly observed fluctuation. PMID:26979652

Sixty Days Remaining, Forty Years of CERN, Two Brothers, One Exclusive Interview

CERN Multimedia

2001-01-01

Twins Marcel and Daniel Genolin while sharing memories of their CERN experiences, point out just how much smaller the Meyrin site once was. In a place such as CERN where the physical sciences are in many ways the essence of our daily lives and where technological advancement is an everyday occurrence, it is easy to lose track of the days, months, and even years. But last week twin brothers, Daniel and Marcel Genolin, hired in the early sixties and getting ready to end their eventful forty year CERN experiences, made it clear that the winds of time bluster past us whether we are aware or not. 'CERN was very small when we started' says Marcel, who has worked in transport during his entire time here. A lot has changed. 'When I got here there were no phones in peoples' houses' he recalls,'when there were problems in the control room with the PS (Proton Synchrotron) they used to get a megaphone and tell us {the transport service} to go and get the necessary physicists from their homes in the area. We had to lo...

Study of extraterrestrial disposal of radioactive wastes. Part 3: Preliminary feasibility screening study of space disposal of the actinide radioactive wastes with 1 percent and 0.1 percent fission product contamination

Science.gov (United States)

Hyland, R. E.; Wohl, M. L.; Finnegan, P. M.

1973-01-01

A preliminary study was conducted of the feasibility of space disposal of the actinide class of radioactive waste material. This waste was assumed to contain 1 and 0.1 percent residual fission products, since it may not be feasible to completely separate the actinides. The actinides are a small fraction of the total waste but they remain radioactive much longer than the other wastes and must be isolated from human encounter for tens of thousands of years. Results indicate that space disposal is promising but more study is required, particularly in the area of safety. The minimum cost of space transportation would increase the consumer electric utility bill by the order of 1 percent for earth escape and 3 percent for solar escape. The waste package in this phase of the study was designed for normal operating conditions only; the design of next phase of the study will include provisions for accident safety. The number of shuttle launches per year required to dispose of all U.S. generated actinide waste with 0.1 percent residual fission products varies between 3 and 15 in 1985 and between 25 and 110 by 2000. The lower values assume earth escape (solar orbit) and the higher values are for escape from the solar system.

Accumulation and mobility of cesium in roots of tulip popular seedlings

International Nuclear Information System (INIS)

Cox, T.L.

1975-01-01

Tulip poplar, Liriodendron tulipifera L., seedlings were stem-well tagged with cesium, periodically harvested, and separated into root and shoot compartments to determine seasonal cesium distributions in different root-diameter classes and to delineate element pathways to forest soils. The cesium concentration (μCi/g) in roots less than 0.1 cm in diameter averaged 1.5 and 3.0 times greater than in roots in the 0.5- to 0.1-cm- and 1.0- to 0.5-cm-diameter classes, respectively. Roots contained 24 percent of the seedling pool of cesium in 1 week and about 40 percent in 7 weeks after inoculation. Sixty-five percent of the seedling content was in the root system 8 months after tagging. On an annual basis, roots of the less than 0.5-cm-diameter classes contained an average of 36 percent of the seedling pool (root and shoot) and 72 percent of the root pool of cesium. This is important because small roots constituted a considerable portion of the annual turnover in these root systems. Soil content of cesium (3.37 μCi) at the termination of the study and analysis of treatment effects (aboveground inputs to soil allowed or not allowed) indicated that root processes contributed twice as much cesium to the soil during the study period as the combined aboveground processes contributed

Childcare issue and family care issue are critical factors for women doctors to make a career as a neurologist in Japan. To know the actual business conditions of Japanese neurologists an online questioner survey was conducted. Answers were obtained from 737 members of Japanese Society of Neurology and 21 neurological medical facilities. Most of the answers were form members at three major metropolitan areas such as Tokyo, Osaka and Nagoya. Nobody from some prefectures was replied any answer. Almost sixty percent woman doctors had to change their working style from full time to part time at their child raising period and had difficulty with returning to full time job. Some neurologists have answered they used paid vacation to care their families and they felt they could not keep it for a longer period. At 70 percent of medical facilities sick child day care center were not operated. Opinions form members extremely varied from "In the first place woman doctors are unnecessary"to "With the help of the partner I have survived my child raising period".

Hernandez, Lisa

2014-01-01

Welcome to The Amazing 7-Day, Super-Simple, Scripted Guide to Teaching or Learning Percents. I have attempted to do just what the title says: make learning percents super simple. I have also attempted to make it fun and even ear-catching. The reason for this is not that I am a frustrated stand-up comic, but because in my fourteen years of teaching the subject, I have come to realize that my jokes, even the bad ones, have a crazy way of sticking in my students' heads. And should I use a joke (even a bad one) repetitively, the associations become embedded in their brains, many times to their cha

MFT homogeneity study at TNX: Final report on the low weight percent solids concentration

International Nuclear Information System (INIS)

Jenkins, W.J.

1993-01-01

A statistical design and analysis of both elemental analyses and weight percent solids analyses data was utilized to evaluate the MFT homogeneity at low heel levels and low agitator speed at both high and low solids feed concentrations. The homogeneity was also evaluated at both low and high agitator speed at the 6000+ gallons static level. The dynamic level portion of the test simulated feeding the Melter from the MFT to evaluate the uniformity of the solids slurry composition (Frit-PHA-Sludge) entering the melter from the MFT. This final report provides the results and conclusions from the second half of the study, the low weight percent solids concentration portion, as well as a comparison with the results from the first half of the study, the high weight percent solids portion

2006-01-01

We carried out a questionnaire survey to determine the actual situation of radiation safety management measures in all medical institutions in Japan that had nuclear medicine facilities. The questionnaire consisted of questions concerning the evaluation of shielding capacity; radiation measurement; periodic checks of installations, equipment, and protection instruments; and the calibration of radiation survey meters. The analysis was undertaken according to region, type of establishment, and number of beds. The overall response rate was 60 percent. For the evaluation of shielding capacity, the outsourcing rate was 53 percent of the total. For the radiation measurements of ''leakage radiation dose and radioactive contamination'' and contamination of radioactive substances in the air'', the outsourcing rates were 28 percent and 35 percent of the total, respectively (p<0.001, according to region and establishment). For the periodic check of radiation protection instruments, the implementation rate was 98 percent, and the outsourcing rate was 32 percent for radiation survey meters and 47 percent for lead aprons. The non-implemented rate for calibration of radiation survey meters was 25 percent of the total (p<0.001, according to region and establishment). The outsourcing rate for calibration of radiation survey meters accounted for 87 percent of the total, and of these medical institutions, 72 percent undertook annual calibration. The implementation rate for patient exposure measurement was 20 percent of the total (p<0.001, according to number of beds), and of these medical institutions 46 percent recorded measurement outcome.

To analyze the characteristics of hepatotoxicity due to ticlopidine. We describe all the case of hepatotoxicity attributed to ticlopidine and reported to the Register of drug associated hepatopathies. We also obtained data from MEDLINE and the Spanish Medical Index regarding cases reported during the period 1982 2001. We reported twelve cases of hepatopathy related to the use of ticlopidine. These made up 5% of all the cases notified to the Register. Eighty three percent of the patients were male, and of an average age of 68 years. Sixty six percent required hospital admission. The latent period varied between 2 and 13 weeks. The liver lesion was of cholestatic type in 75% of the cases, hepatocellular in 16.6% and mixed in 8.3%. Twenty five percent of the patients had received sub therapeutic doses. Ticlopidine is often related to hepatotoxicity. This seems to be due to an idiosyncratic mechanism and is mainly cholestatic. The use of lower dosage than that recommended means that the desired therapeutic effect is not attained but does not protect against the development of hepatotoxicity. Doctors who use this drug should be aware of this so as to establish the true risk benefit relation.

The proliferation of post-modern religiosity in the late sixties: the case of ’The Process Church of the Final Judgement’: from psychoanalysis as therapy to psychoanalysis as theology

Marco Toti

2008-01-01

Full Text Available The sixties may be considered as a true turning point in the history of the West. It may be correctly stated that the counterculture ‘revolution’, which has characterized Western civilization since the sixties, gave rise to further acceleration of what has been called ‘post-modernity’, the most important character of which is the revaluation of the ‘religious’ and the detachment of the category of ‘sacred’—the divinity being generally considered as ‘impersonal’ and in terms of ‘energy’—from traditional religions.

Results. The number of CT examinations doubled over the study period. While increases in numbers of recorded examinations were seen across all age groups, the greatest increases were in the older patients, most notably those aged 15–19 years of age. Sixty percent of CT examinations were of the head, with the percentages varying with calendar year and patient age. Conclusions. In contrast to previous data from the North of England, the doubling of CT use was not accompanied by an increase in numbers of multiple examinations to the same individual.

Full Text Available Background: Transbronchial lung biopsy (TBLB is an attractive alternative to open lung biopsy as an initial diagnostic procedure for patients with diffuse parenchymal disease or localized densities beyond direct endoscopic vision. TBLB can be carried out safely without fluoroscopy in patients with diffuse lung disease. Since in our bronchoscopic department fluoroscopy is not available, we planned to evaluate the blind (without fluoroscopic guide TBLB being performed in our department to determine the success rate in obtaining lung tissue, the sensitivity of the procedure and the risk of complications. Materials and Methods: Sixty-Four TBLB were done in our department during a 6 month period (March-September 1999. Results: Lung tissue wasn’t detected in two (3.1 percent samples. Pathological results were helpful in 46 (71.9 percent cases. No evidence of hemoptysis was found after the procedure. Three (4.68 percent cases of pneumothorax was detected. Only one of them required chest tube (1.51 percent. Conclusion: We concluded that blind TBLB was successful in our department with rates of complications comparable to other approved centers.

Collectively agreed reductions of working hours phased out in Europe in the 1990s. During the last two decades, working time became more flexible and heterogeneous. Working hours of full-time employees in the EU hardly changed. The strong increase in part-time work was the outstanding phenomenon. Today, one third of female employees and almost ten percent of male employees work part-time. In a period of slow growth, productivity gains will be squeezed by subdued investment and low capacity ut...

2012-01-01

Full Text Available Natural environment, social and physiological factors have impacts on rhyme, identical rhyme and rhythm. The influences of these factors on music of poetry of Khaghani and Masih have been analyzed. First, the rhythm of poems which were selected from two different periods is extracted and classified according to the point of view of scientists of metrics and rhyme. Based on the opinion of sociologist literature rhyme and meter of the poems analyzed. The result shows that more than fifty percent of Khaghani’s poems with the shirt rhyme and more than sixty percent of Masih’s poems with the moderate rhythms hefty have composed, which shows the impact of social factors on rhythms of poems. The effect of social factors on music of poetry is more than physiological effects. This study by research of Masih’s poems in two different social spaces was found that usage of long and short rhythms fifty twelve percent increased by changing the environment.

Current versus ideal skin tones and tanning behaviors in Caucasian college women.

Science.gov (United States)

Hemrich, Ashley; Pawlow, Laura; Pomerantz, Andrew; Segrist, Dan

2014-01-01

To explore tanning behaviors and whether a discrepancy between current and ideal skin tones exists. The sample included 78 Caucasian women from a mid-sized midwestern university. Data were collected in spring 2012 via a paper questionnaire. Sixty-two percent of the sample regularly engaged in salon tanning at least once per week, with an average frequency of 2.5 visits per week. Thirteen percent endorsed regularly tanning 4 or more times per week, and 26% reported visiting a tanning bed more than once in a 24-hour period. Ninety-four percent wished their current skin tone was darker, and ideal tone was significantly darker than current tone. The data suggest that the young Caucasian women in this sample tend to be dissatisfied with their current skin tone to an extent that leads the majority of them to engage in risky, potentially cancer-causing behavior by either salon tanning or considering tanning in the future as time and finances become available.

In this study, we aimed to evaluate some laboratory and clinical factors in the prediction of latency period for pregnant patients complicated with preterm premature rupture of the membranes. Sixty-five pregnant patients between 24 and 34 weeks of gestation, who were admitted to University of Çukurova School of Medicine Hospital with the diagnosis of preterm premature rupture of the membranes (PPROM) between January 01, 2013 and December 31, 2013, were included in this study. Serum CRP, procalcitonin, sedimentation rate, leukocyte count and cervical length (measured with transvaginal ultrasound) of patients were analyzed for the correlation with the latency period. None of the parameters were found to be correlated with the latency period. However, patients with cervical length of premature rupture of the membranes is thought to be either an infection-based disease or a disease increasing the risk of infectious complications, major infection markers are not found to be helpful criteria for the prediction of latency period. Patients with a cervical length of <25 mm can be expected to deliver earlier and, therefore, can be referred to a tertiary center earlier.

Mathany, Timothy M.

2017-03-09

The Priority Basin Project (PBP) of the Groundwater Ambient Monitoring and Assessment (GAMA) program was developed in response to the Groundwater Quality Monitoring Act of 2001 and is being conducted by the U.S. Geological Survey in cooperation with the California State Water Resources Control Board. From 2004 through 2012, the GAMA-PBP collected samples and assessed the quality of groundwater resources that supply public drinking water in 35 study units across the State. Selected sites in each study unit were sampled again approximately 3 years after initial sampling as part of an assessment of temporal trends in water quality by the GAMA-PBP. Twelve of the study units, initially sampled during 2006–11 (initial sampling period) and sampled a second time during 2008–13 (trend sampling period) to assess temporal trends, are the subject of this report.The initial sampling was designed to provide a spatially unbiased assessment of the quality of untreated groundwater used for public water supplies in the 12 study units. In these study units, 550 sampling sites were selected by using a spatially distributed, randomized, grid-based method to provide spatially unbiased representation of the areas assessed (grid sites, also called “status sites”). After the initial sampling period, 76 of the previously sampled status sites (approximately 10 percent in each study unit) were randomly selected for trend sampling (“trend sites”). The 12 study units sampled both during the initial sampling and during the trend sampling period were distributed among 6 hydrogeologic provinces: Coastal (Northern and Southern), Transverse Ranges and Selected Peninsular Ranges, Klamath, Modoc Plateau and Cascades, and Sierra Nevada Hydrogeologic Provinces. For the purposes of this trend report, the six hydrogeologic provinces were grouped into two hydrogeologic regions based on location: Coastal and Mountain.The groundwater samples were analyzed for a number of synthetic organic

Full Text Available Background: The causative agent spectrum and resistance patterns of urinary tract infections in children are affected by many factors. Aims: To demonstrate antibiotic resistance in urinary tract infections and changing ratio in antibiotic resistance by years. Study Design: Retrospective cross-sectional study. Methods: We analysed antibiotic resistance patterns of isolated Gram (- bacteria during the years 2011-2014 (study period 2 in children with urinary tract infections. We compared these findings with data collected in the same centre in 2001-2003 (study period 1. Results: Four hundred and sixty-five uncomplicated community-acquired Gram (- urinary tract infections were analysed from 2001-2003 and 400 from 2011-2014. Sixty-one percent of patients were female (1.5 girls : 1 boy. The mean age of children included in the study was 3 years and 9 months. Escherichia coli was the predominant bacteria isolated during both periods of the study (60% in study period 1 and 73% in study period 2. Bacteria other than E. coli demonstrated a higher level of resistance to all of the antimicrobials except trimethoprim-sulfamethoxazole than E. coli bacteria during the years 2011-2014. In our study, we found increasing resistance trends of urinary pathogens for cefixime (from 1% to 15%, p0.05. Conclusion: In childhood urinary tract infections, antibiotic resistance should be evaluated periodically and empiric antimicrobial therapy should be decided according to antibiotic sensitivity results

This report discusses the report discusses whether the MICE absorbers can be characterized to ±0.3 percent, so that one predict absorber ionization cooling within the absorber. This report shows that most solid absorbers can be characterized to much better than ±0.3 percent. The two issues that dominate the characterization of the liquid cryogen absorbers are the dimensions of the liquid in the vessel and the density of the cryogenic liquid. The thickness of the window also plays a role. This report will show that a liquid hydrogen absorber can be characterized to better than ±0.3 percent, but a liquid helium absorber cannot be characterized to better and ±1 percent

The state of cancer survivorship programming in Commission on Cancer-accredited hospitals in Georgia.

Science.gov (United States)

Kirsch, Logan J; Patterson, Angela; Lipscomb, Joseph

2015-03-01

In Georgia, there are more than 356,000 cancer survivors. Although many encounter challenges as a result of treatment, there is limited data on the availability of survivorship programming. This paper highlights findings from two surveys assessing survivorship care in Commission on Cancer (CoC)-accredited hospitals in Georgia. In 2010, 38 CoC-accredited hospitals were approached to complete a 36-item survey exploring knowledge of national standards and use of survivorship care plans (SCPs), treatment summaries (TSs), and psychosocial assessment tools. In 2012, 37 CoC-accredited hospitals were asked to complete a similar 21-item survey. Seventy-nine percent (n = 30) of cancer centers completed the 2010 survey. Sixty percent (n = 18) reported having a cancer survivorship program in place or in development. Forty-three percent (n = 13) provided survivors with a SCP and 40% (n = 12) a TS. Sixty percent (n = 18) reported either never or rarely using a psychosocial assessment tool. Sixty-two percent (n = 23) completed the 2012 survey. Ninety-six percent (n = 22) were aware of the new CoC guideline 3.3. Thirty-nine percent (n = 9) provided a SCP and/or TS. Eighty-seven percent (n = 20) stated they were very confident or somewhat confident their organization could implement a SCP and/or TS by 2015. The data indicated the importance of collaboration and shared responsibility for survivorship care. Broad implementation of SCPs and TSs can help address the late and long-term effects of treatment. Increasing knowledge on survivorship care is imperative as the Georgia oncology community engages oncologists and primary care providers to achieve higher quality of life for all survivors.

TEM investigation of irradiated U-7 weight percent Mo dispersion fuel

International Nuclear Information System (INIS)

Van den Berghe, S.

2009-01-01

In the FUTURE experiment, fuel plates containing U-7 weight percent Mo atomized powder were irradiated in the BR2 reactor. At a burn-up of approximately 33 percent 235 U (6.5 percent FIMA or 1.41 10 21 fissions/cm 3 meat), the fuel plates showed an important deformation and the irradiation was stopped. The plates were submitted to detailed PIE at the Laboratory for High and Medium level Activity. The results of these examinations were reported in the scientific report of last year and published in open literature. Since then, the microstructural aspects of the FUTURE fuel were studied in more detail using transmission electron microscopy (TEM), in an attempt to understand the nature of the interaction phase and the fission gas behavior in the atomized U(Mo) fuel. The FUTURE experiment is regarded as the definitive proof that the classical atomized U(Mo) dispersion fuel is not stable under irradiation, at least in the conditions required for normal operation of plate-type fuel. The main cause for the instability was identified to be the irradiation behavior of the U(Mo)-Al interaction phase which is formed between the U(Mo) particles and the pure aluminum matrix during irradiation. It is assumed to become amorphous under irradiation and as such cannot retain the fission gas in stable bubbles. As a consequence, gas filled voids are generated between the interaction layer and the matrix, resulting in fuel plate pillowing and failure. The objective of the TEM investigation was the confirmation of this assumption of the amorphisation of the interaction phase. A deeper understanding of the actual nature of this layer and the fission gas behaviour in these fuels in general can allow a more oriented search for a solution to the fuel failures

Malaria causes around 863,000 deaths per year, mostly of them in children under 5 years old. We have reviewed the epidemiological data of malaria cases in a pediatric department in a Hospital in the Community of Madrid, in the period 1996-2011. In the period reviewed, 103 cases of malaria were diagnosed in children under 14 years old. Sixty percent were males and the average age was 4.5 years. In most cases, the infection arose during a visit to relatives in the country of origin. The vast majority did not have malaria prophylaxis. Twenty-five percent of the cases were diagnosed as complicated malaria, the main criteria being hyperparasitemia, of which 80% of the patients did not present any other complications A high level of suspicion must be maintained in any patient who comes from a malaria endemic area. The key factor responsible for the infection was the lack of chemoprophylaxis. Copyright © 2013 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

Chow, C.K.; Liner, Y.; Rigby, G.L.

1984-08-01

The kinetics of the α → β phase change in Zr-2.5 percent Nb pressure-tube material at constant temperature have been studied. The volume-fraction change of the β phase due to diffusion in an infinite α-phase matrix was considered, and a mathematical model with a numerical solution was developed to predict the transient spherical growth of the β-phase region. This model has been applied to Zr-2.5 wt percent Nb, and the calculated results compared to experiment

To quantify and describe trampoline-related injuries in children attending an urban pediatric emergency department. Retrospective cohort study of consecutive patients attending a children's emergency department with trampoline-related injuries over a 3-month period (May-July 2005). One hundred and sixty-eight children were treated for trampoline-related injuries during the period reviewed. Sixty-three percent were girls. Their age ranged between 4 months and 16 years (mean, 10.4 years [SD, 3 years and 10 months]). Lower limb injuries (51%) were more common overall. The most common injuries were to the ankle (31%), followed by foot (9.2%), and neck (8.4%). Sprain or soft tissue injuries (68%) were the most common type of injury, followed by fracture (12.2%). The most common mechanism of injury was inversion of the ankle on a trampoline (18.4%). Trampoline-related injuries represented 2.5% of morbidity from accidental trauma in children presenting to emergency department in our study. The rate and severity of injury has become a significant public health concern. It appears that current preventative strategies are inadequate in making children's carers aware of the potential risks of trampoline use, particularly when used recreationally.

Development and Cross-Validation of Equation for Estimating Percent Body Fat of Korean Adults According to Body Mass Index

Directory of Open Access Journals (Sweden)

Hoyong Sung

2017-06-01

Full Text Available Background : Using BMI as an independent variable is the easiest way to estimate percent body fat. Thus far, few studies have investigated the development and cross-validation of an equation for estimating the percent body fat of Korean adults according to the BMI. The goals of this study were the development and cross-validation of an equation for estimating the percent fat of representative Korean adults using the BMI. Methods : Samples were obtained from the Korea National Health and Nutrition Examination Survey between 2008 and 2011. The samples from 2008-2009 and 2010-2011 were labeled as the validation group (n=10,624 and the cross-validation group (n=8,291, respectively. The percent fat was measured using dual-energy X-ray absorptiometry, and the body mass index, gender, and age were included as independent variables to estimate the measured percent fat. The coefficient of determination (R², standard error of estimation (SEE, and total error (TE were calculated to examine the accuracy of the developed equation. Results : The cross-validated R² was 0.731 for Model 1 and 0.735 for Model 2. The SEE was 3.978 for Model 1 and 3.951 for Model 2. The equations developed in this study are more accurate for estimating percent fat of the cross-validation group than those previously published by other researchers. Conclusion : The newly developed equations are comparatively accurate for the estimation of the percent fat of Korean adults.

Anesthetists come in contact with more than two-third of hospital patients. Timely referral to anesthetists is vital in perioperative and remote site settings. Delayed referrals, improper referrals, and referrals at inappropriate levels can result in inadequate preparation, perioperative complications, and poor outcome. The self administered paper survey to delegates attending anesthesia conferences. Questions were asked on how high-risk, emergency surgical cases remote site and critical care patients were referred to anesthetists and presence of rapid response teams. The response rate was 43.8%. Sixty percent (55.3-64.8, P - 0.001) reported high-risk elective cases were referred after admission. Sixty-eight percent (63.42-72.45, P - 0.001) opined preoperative resting echocardiographs were useful. Six percent (4.16-8.98, P - 0.001) reported emergency room referral before arrival of the patient. Twenty-five percent (20.92-29.42, P - 0.001) indicated high-risk obstetric cases were referred immediately after admission. Consultants practiced preoperative stabilization more commonly than residents (32% vs. 22%) ( P - 0.004). For emergency surgery, resident referrals occurred after surgery time was fixed (40% vs. 28%) ( P - 0.012). Residents dealt with more cases without full investigations in obstetrics (28% vs. 15) ( P = 0.002). Remote site patients were commonly referred to residents after sedation attempts (32% vs. 20%) ( P = 0.036). Only 34.8 said hosptals where tbey practiced had dedicated cardiac arrest team in place. Anesthetic departments must periodically assess whether subgroups of patients are being referred in line with current guidelines. Cancellations, critical incidents and complications arising out of referral delays, and improper referrals must be recorded as referral incidents and a separate referral incident registry must be maintained in each department. Regular referral audits must be encouraged.

Describe current dental sedation practice for under 19-year-olds in the UK and compare it with the recommendations of NICE guidance 112. Members of the Society for the Advancement of Anaesthesia in Dentistry and members of the Dental Sedation Teachers Group were invited to participate in an online survey. Two hundred and sixty-six dentists and doctors completed the survey. Eighty-two percent were operator and sedationist (operator-sedationist). Ninety-five percent provided written information and 94% obtained written consent. Eighty-four percent kept a written or electronic sedation record. Eighty-six percent complied with life support training expectations. Eighty-six percent had immediate access to resuscitation equipment. Sixty-seven percent of sedationists reported that treatment could not be completed under sedation for sedation was unsuccessful, 61% said they would schedule general anaesthesia and 54.5% would schedule advanced sedation care. Forty-nine percent believed that a dentist was an appropriate person to provide advanced sedation for 12-18 years. Only 24% thought a dentist should provide advanced sedation for childrensedation was thought to be primary care by 33% and secondary care by 68%. We found good agreement between the current practice of sedation and the recommendations of the NICE guidance 112.

Austrian Business Cycle Theory: Are 100 Percent Reserves Sufficient to Prevent a Business Cycle?

Directory of Open Access Journals (Sweden)

Philipp Bagus

2010-02-01

Full Text Available Authors in the Austrian tradition have made the credit expansion of a fractional reserve banking system as the prime cause of business cycles. Authors such as Selgin (1988 and White (1999 have argued that a solution to this problem would be a free banking system. They maintain that the competition between banks would limit the credit expansion effectively. Other authors such as Rothbard (1991 and Huerta de Soto (2006 have gone further and advocated a 100 percent reserve banking system ruling out credit expansion altogether. In this article it is argued that a 100 percent reserve system can still bring about business cycles through excessive maturity mismatching between deposits and loans.

The purpose of this study was to investigate the effect of combined linear and nonlinear periodic training on physical fitness and competition times in finswimmers. The linear resistance training model (6 days/week) and nonlinear underwater training (4 days/week) were applied to 12 finswimmers (age, 16.08± 1.44 yr; career, 3.78± 1.90 yr) for 12 weeks. Body composition measures included weight, body mass index (BMI), percent fat, and fat-free mass. Physical fitness measures included trunk flexion forward, trunk extension backward, sargent jump, 1-repetition-maximum (1 RM) squat, 1 RM dead lift, knee extension, knee flexion, trunk extension, trunk flexion, and competition times. Body composition and physical fitness were improved after the 12-week periodic training program. Weight, BMI, and percent fat were significantly decreased, and trunk flexion forward, trunk extension backward, sargent jump, 1 RM squat, 1 RM dead lift, and knee extension (right) were significantly increased. The 50- and 100-m times significantly decreased in all 12 athletes. After 12 weeks of training, all finswimmers who participated in this study improved their times in a public competition. These data indicate that combined linear and nonlinear periodic training enhanced the physical fitness and competition times in finswimmers.

O'Sullivan, S S

2012-02-03

OBJECTIVE: The purpose of this work was to assess the opinion of general practitioners (GPs) regarding the diagnosis of psychogenic nonepileptic seizures (PNES) and the role they feel they should play in the management of the disorder. METHODS: Patients with PNES were identified from hospital records. Seizure and patient characteristics were recorded. Their GPs were surveyed regarding their understanding of the diagnosis and ongoing management of PNES. RESULTS: Twenty-three patients were identified over a 3-year period as having been diagnosed with PNES. Sixty-five percent of GPs agreed with the diagnosis, and when asked to grade their understanding of the diagnosis (poor = 1, excellent = 10), the mean score was 5.7 (+\\/-SD 2.3). Thirty-five percent of GPs felt psychological input was of benefit to their patients. Fifty-two percent of GPs felt comfortable following up these patients, either with or without neurology outpatient services. CONCLUSIONS: PNES remains a difficult disease to manage. There is a high level of uncertainty regarding the optimum management of PNES among primary care physicians, for which further education is needed.

Full Text Available Percent of latewood of Boguchany and Suzun Scots pine climatypes has been studied in two provenance trials (place of origin and trial place. For Boguchany climatype the place of origin is south taiga of Central Siberia (Krasnoyarsk Krai, the place of trial is forest-steppe zone of Western Siberia (Novosibirsk Oblast and vice versa for Suzun climatype – forest-steppe zone of Western Siberia is the place of origin, south taiga is the place of trial. Comparison of annual average values of latewood percent of Boguchany climatype in south taiga and forest-steppe revealed the same numbers – 19 %. Annual variability of this trait in south taiga is distinctly lower and equal to 17 %, in forest-steppe – 35 %. Average annual values of latewood percent of Suzun climatype in the place of origin and trial place are close (20 and 21 %. Variability of this trait for Suzun climatype is higher than for Boguchany and equal to 23 % in south taiga and 42 % in forest-steppe. Climatic conditions in southern taiga in Central Siberia in comparison with forest-steppe in Western Siberia make differences between climatypes stronger. Differences between climatypes are expressed in different age of maximal increments of diameter, different tree ring width and latewood percent values and in different latewood reaction to weather conditions.

Patients may require microvascular free tissue transfer (MFTT) following re-irradiation for recurrent cancer or radiation complications. The objective of this study was to describe the indications for and outcomes of free flaps performed in twice-radiated patients. A retrospective chart review identified the indications for and outcomes of 36 free flaps performed on 29 twice-irradiated patients. The free flap success rate was 92%. The most common indications requiring MFTT were cancer recurrence and osteoradionecrosis. Sixty-one percent experienced postoperative complications, most commonly wound infection (33%). Twenty-five percent of the procedures required return to the operating room due to postoperative complication. MFTT can be successfully performed in the twice-irradiated patient population with a success rate comparable to singly-radiated patients. Despite a high success rate, there is also a high rate of surgical site complications, especially infection. © 2017 Wiley Periodicals, Inc.

To determine the incidence of surgical site infection in knee prosthesis surgical procedure for a follow-up period of one year in twelve hospitals in Madrid region. A prospective study was carried out from January to December 2009 using a national surveillance system called Indicadores Clínicos de Mejora Continua de Calidad. Primary and revision knee joint replacements in patients operated on in the previous year were included. Criteria used to define surgical site infection and patient risk index categories were those established by the Centers for Disease Control and Prevention and National Nosocomial Infections Surveillance. The incidence rates were worked out crude and adjusted by hazard ratio. 2,088 knee prosthesis procedures were analyzed. The overall incidence of surgical site infection was 2.1%. Sixty-five percent of the infections were organ/space. Sixty percent of the infections were identified in the early postoperative period. Of all surgical site infections, 41.9% were microbiologically confirmed. Antibiotic prophylaxis was implemented correctly in 63.3% of the cases. The most important cause of inappropriate prophylaxis was an unsuitable duration in 85.7% of the cases. The presurgical preparation was carried out correctly in 50.3% of surgical operations. The incidence of knee arthroplasty infection was twice as high as in the National Healthcare Safety Network and similar to national rates. In this study, the incidence of infection was within the range of infection rates in other published European studies. Surveillance and control strategies of health care for associated infections allow us to assess trends and the impact of preventive measures. Copyright © 2011 SECOT. Published by Elsevier Espana.

Yu, Xinyang; Lu, Changhe

2014-01-01

This study investigated percent impervious surface area (PISA) extracted by a four-endmember normalized spectral mixture analysis (NSMA) method and evaluated the reliability of PISA as an indicator of land surface temperature (LST). Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) images for Yantai city, eastern China obtained from USGS were used as the main data source. The results demonstrated that four-endmember NSMA method performed better than the typical three-endmember one, and there was a strong linear relationship between LST and PISA for the two images, which suggest percent impervious surface area provides an alternative parameter for analyzing LST quantitatively in urban areas

Numerical computing of elastic homogenized coefficients for periodic fibrous tissue

Directory of Open Access Journals (Sweden)

Roman S.

2009-06-01

Full Text Available The homogenization theory in linear elasticity is applied to a periodic array of cylindrical inclusions in rectangular pattern extending to infinity in the inclusions axial direction, such that the deformation of tissue along this last direction is negligible. In the plane of deformation, the homogenization scheme is based on the average strain energy whereas in the third direction it is based on the average normal stress along this direction. Namely, these average quantities have to be the same on a Repeating Unit Cell (RUC of heterogeneous and homogenized media when using a special form of boundary conditions forming by a periodic part and an affine part of displacement. It exists an infinity of RUCs generating the considered array. The computing procedure is tested with different choices of RUC to control that the results of the homogenization process are independent of the kind of RUC we employ. Then, the dependence of the homogenized coefficients on the microstructure can be studied. For instance, a special anisotropy and the role of the inclusion volume are investigated. In the second part of this work, mechanical traction tests are simulated. We consider two kinds of loading, applying a density of force or imposing a displacement. We test five samples of periodic array containing one, four, sixteen, sixty-four and one hundred of RUCs. The evolution of mean stresses, strains and energy with the numbers of inclusions is studied. Evolutions depend on the kind of loading, but not their limits, which could be predicted by simulating traction test of the homogenized medium.

Post Civil War African American History: Brief Periods of Triumph, and Then Despair.

Graff, Gilda

2016-01-01

During Reconstruction, which is often called the most progressive period in American history, African Americans made great strides. By 1868 African American men constituted a majority of registered voters in South Carolina and Mississippi, and by 1870 eighty-five percent of Mississippi's black jurors could read and write. However, Reconstruction was followed by approximately one hundred years of Jim Crow laws, lynching, disenfranchisement, sharecropping, unequal educational resources, terrorism, racial caricatures, and convict leasing. The Civil Rights Revolution finally ended that period of despair, but the era of mass incarceration can be understood as a reaction to the Civil Rights Movement. This article attempts to understand the persistence of racism in the United States from slavery's end until the present.

Disrupting the Continuities Among Residential Schools, the Sixties Scoop, and Child Welfare: An Analysis of Colonial and Neocolonial Discourses

Holly A. McKenzie

2016-04-01

Full Text Available In Canada, it is estimated that 3 times as many Indigenous children are currently in the care of the state compared to when the residential schools’ populations were at their peak. It is imperative that action be taken. This article explores the continuities among residential schools, the Sixties Scoop, and child welfare in Canada today. In particular, we examine how colonial and neocolonial discourses operate through and justify these policies and practices. We propose nine policy recommendations, which aim to transform child welfare and support Indigenous families to care for their children. Although transformative policy change is unlikely within this neocolonial and neoliberal climate, the recent change in federal leadership has made it more possible to move these policy recommendations forward.

Evaluation of the influence of percent labeling of 99mTc-MIBI on nuclear medicine procedures in Recife, Pernambuco State, Brazil

Pereira, Jucilene Maria

2003-08-01

The aim of this work was to evaluate the influence of percent labeling of the radiopharmaceutical 99m Tc-MIBI on the procedures adopted by the nuclear medicine clinics in Recife, Pernambuco State, Brazil, and their possible interference with image quality in myocardial perfusion examinations. This work was performed at two nuclear medicine services in Recife that use pharmaceuticals provided by two different manufacturers: Cardiolite, provided by Dupont and Cardiosyd, provided by SYDMA. The pH, percent labeling and stability of samples of 99m Tc-MIBI and the percent uptake in heart and liver of a number of patients were evaluated. The results showed that the pH values measured in all samples of both radiopharmaceuticals were within the limits recommended. In 48% of the Cardiolite samples, the percent labeling was less than 90%, which is the minimum recommended limit. On the other hand, 87,5% of the Cardiosyd samples measured values above 98%. Both radiopharmaceuticals had good labeling stability, even in samples with low percent labeling efficiencies. In spite of the higher percent labeling of Cardiosyd its heart uptake is similar to that observed with the Cardiolite, even when the percent labeling is lower than 90%. On the other hand, the image quality, according to physicians, evaluation was poorer for Cardiosyd images, due to high noise and poor sharpness. (author)

2017-01-01

Multilevel posterior spine fusion is associated with significant intraoperative blood loss. Tranexamic acid is an antifibrinolytic agent that reduces intraoperative blood loss. The goal of this study was to compare the percent of total blood volume lost during posterior spinal fusion (PSF) with or without tranexamic acid in patients with adolescent idiopathic scoliosis (AIS). Thirty-six AIS patients underwent PSF in 2011-2014; the last half (n=18) received intraoperative tranexamic acid. We retrieved relevant demographic, hematologic, intraoperative and outcomes information from medical records. The primary outcome was the percent of total blood volume lost, calculated from estimates of intraoperative blood loss (numerator) and estimated total blood volume per patient (denominator, via Nadler's equations). Unadjusted outcomes were compared using standard statistical tests. Tranexamic acid and no-tranexamic acid groups were similar (all p>0.05) in mean age (16.1 vs. 15.2 years), sex (89% vs. 83% female), body mass index (22.2 vs. 20.2 kg/m2), preoperative hemoglobin (13.9 vs. 13.9 g/dl), mean spinal levels fused (10.5 vs. 9.6), osteotomies (1.6 vs. 0.9) and operative duration (6.1 hours, both). The percent of total blood volume lost (TBVL) was significantly lower in the tranexamic acid-treated vs. no-tranexamic acid group (median 8.23% vs. 14.30%, p = 0.032); percent TBVL per level fused was significantly lower with tranexamic acid than without it (1.1% vs. 1.8%, p=0.048). Estimated blood loss (milliliters) was similar across groups. Tranexamic acid significantly reduced the percentage of total blood volume lost versus no tranexamic acid in AIS patients who underwent PSF using a standardized blood loss measure.Level of Evidence: 3. Institutional Review Board status: This medical record chart review (minimal risk) study was approved by the University of Minnesota Institutional Review Board.

Facial hypoesthesia is one of the most troublesome complaints in the management of facial bone fractures. However, there is a lack of literature on facial sensory recovery after facial trauma. The purpose of this study was to evaluate the facial sensory recovery period for facial bone fractures using Neurometer. Sixty-three patients who underwent open reduction of zygomatic and blowout fractures between December 2013 and July 2015 were included in the study. The facial sensory status of the patients was repeatedly examined preoperatively and postoperatively by Neurometer current perception threshold (CPT) until the results were normalized. Among the 63 subjects, 30 patients had normal Neurometer results preoperatively and postoperatively. According to fracture types, 17 patients with blowout fracture had a median recovery period of 0.25 months. Twelve patients with zygomatic fracture had a median recovery period of 1.00 month. Four patients with both fracture types had a median recovery period of 0.625 months. The median recovery period of all 33 patients was 0.25 months. There was no statistically significant difference in the sensory recovery period between types and subgroups of zygomatic and blowout fractures. In addition, there was no statistically significant difference in the sensory recovery period according to Neurometer results and the patients' own subjective reports. Neurometer CPT is effective for evaluating and comparing preoperative and postoperative facial sensory status and evaluating the sensory recovery period in facial bone fracture patients.

Colon injury has been associated with a high risk of septic complications and mortality. We prospectively studied the pattern, management, outcome, and prognostic factors in patients who sustained penetrating colon injuries. Sixty patients who presented to our hospital with penetrating colon injuries over a ten-year period (1992 to 2001) were studied. Colon wounds were caused by gunshots in 55 (91.7 percent) patients and knife stabs in 5 (8.3 percent). There was a delay of more than 12 hours before laparotomy in 30 (50 percent) patients. Moderate or major fecal contamination of the peritoneal cavity occurred in 58 (96.7 percent) patients. The average penetrating abdominal trauma index score was 25.9 and 20 (33.3 percent) patients sustained Flint Grade 3 colon injury. Associated intra-abdominal injuries occurred in the small bowel (73.3 percent), liver (25 percent), stomach (23.3 percent), and mesentery (16.7 percent). Right colon wounds (35) were managed by primary repair in 24 (68.6 percent) patients and proximal diverting colostomy in 11 (31.4 percent), whereas left colon wounds (25) were managed by diverting colostomy in 22 (88.0 percent) patients and primary repair in 3 (12.0 percent) patients. Common complications included wound infection (56.7 percent), septicemia (31.7 percent), and enterocutaneous fistula (16.7 percent). The overall mortality rate was 33.3 percent and colon injury-related mortality was 21.7 percent. Presence of destructive colon injury was associated with a greater than fourfold increased incidence of death. Other significant risk factors included shock on admission, major fecal contamination, duration of operation more than four hours, penetrating abdominal trauma index score >25, and more than two postoperative complications. There was no difference in outcome between patients who had primary repair and those undergoing diverting colostomy. Colostomy closure-related morbidity was 21 percent and mortality was 5.3 percent.

Sixty years of the International Journal of Biometeorology.

Science.gov (United States)

Sheridan, Scott C; Allen, Michael J

2017-09-01

The International Journal of Biometeorology (IJB) has continuously evolved since its first publications in 1957. In this paper, we examine these changes using a database that includes all manuscript titles and author information. A brief history considers the development of the journal and shifts over time. With an interdisciplinary focus, publications draw on a wide array of subdisciplines. Using content analysis, we evaluate the themes found within IJB. Some research themes have maintained prominence throughout the journal's history, while other themes have waxed or waned over time. Similarly, the most influential manuscripts throughout the past 60 years reveal that human biometeorological papers, particularly regarding thermal comfort, have been influential throughout the journal's history, with other themes, including phenology and animal biometeorology, more concentrated in specific periods. Dominated by North America and Europe in the early years, publication authorship has shifted over the last decade to be more globally representative. Recent inclusion of special issues devoted to regional biometeorological issues, as well as to Students and New Professionals, offer insight into the future direction of the IJB.

Evaluation of environmental qualification period for Conax electrical penetration assemblies. Final report

International Nuclear Information System (INIS)

Doroshuk, B.; Hager, M.; Brown, R.

1995-05-01

This report evaluates the environmental qualification period of Conax electrical penetration assemblies (EPAs) for extension from forty (40) years to sixty (60) years. The evaluation was performed based on a review of Conax EPAs supplied to Baltimore Gas ampersand Electric's (BGE) Calvert Cliffs Nuclear Power Plant Units 1 and 2. The report has been prepared so that it may be of use to any utility involved in the extension of the environmental qualification period for Conax EPAs installed in their plant(s). The report includes a section on the strategy which was developed for the effort to extend the qualified lives of the Conax EPAs. A review of documentation and plant conditions specific to BGE is included in the report to demonstrate the methodology. The documentation included qualification testing performed by Conax of the materials of construction of the EPA models. The plant conditions reviewed included both normal and accident environments, both of which are specific to Calvert Cliffs Nuclear Power Plant Units 1 and 2. This report can be used as a guide in the evaluation of similar installations of Conax electrical penetration assemblies in other nuclear power plants by applying the methodologies used herein in conjunction with the plant specific test reports, materials, and conditions

Scheers, Tineke; Philippaerts, Renaat; Lefevre, Johan

2013-12-01

This study examined the independent and joint associations of overall, intensity-specific and domain-specific physical activity and sedentary behavior with bioelectrical impedance-determined percent body fat. Physical activity was measured in 442 Flemish adults (41.4 ± 9.8 years) using the SenseWear Armband and an electronic diary. Two-way analyses of covariance investigated the interaction of physical activity and sedentary behavior with percent body fat. Multiple linear regression analyses, adjusted for potential confounders, examined the associations of intensity-specific and domain-specific physical activity and sedentary behavior with percent body fat. Results showed a significant main effect for physical activity in both genders and for sedentary behavior in women, but no interaction effects. Light activity was positively (β = 0.41 for men and 0.43 for women) and moderate (β = -0.64 and -0.41), vigorous (β = -0.21 and -0.24) and moderate-to-vigorous physical activity (MVPA) inversely associated with percent body fat, independent of sedentary time. Regarding domain-specific physical activity, significant associations were present for occupation, leisure time and household chores, irrespective of sedentary time. The positive associations between body fat and total and domain-specific sedentary behavior diminished after MVPA was controlled for. MVPA during leisure time, occupation and household chores may be essential to prevent fat gain. Copyright © 2013 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Attitudes toward Palliative Care and End of Life Issues: A Prospective Survey in Patients with Metastatic Cancer

LENUS (Irish Health Repository)

Docherty, C

2016-05-01

Palliative care (PC) positively impacts patient outcomes, decreases hospital admissions and improves quality of life. Despite evidence, PC resources are reported as under-utilised. Few studies have explored patient attitudes towards PC. This study evaluated patient attitudes towards PC. It was a prospective study conducted in oncology outpatient clinics. A 26-item questionnaire was distributed to those with metastatic cancer (N = 44). Sixty percent believed PC can make people ‘feel better’, 63.4% believed PC is offered when nothing more can be done. Most were unsure or disagreed that opioids are addictive. Eighty percent reported symptom control is more important than prolonging life. Sixty-one percent strongly agreed or agreed that ‘losing hope makes people die sooner’. Although PC was deemed beneficial, a significant relationship exists between familiarity with PC and thinking it’s offered when ‘nothing more can be done’. Lack of knowledge about opioids, preference for symptom control over life prolonging measures and the importance of hope were also emphasised.

Haroon, Muhammad; Yasin, Faiza; Eckel, Rachael; Walker, Frank

2010-10-01

Our objective was to document the pattern of mobile phone usage by medical staff in a hospital setting, and to explore any perceived benefits (such as improved communications) associated with mobile phones. This cross-sectional survey was conducted in Waterford Regional Hospital, Ireland, where bleep is the official system of communication. All non-consultant hospital doctors, of medical disciplines only, were asked to participate. The questionnaire was designed to explore the pattern and different aspects of mobile phone usage. At the time of study, there were sixty medical junior doctors, and the response rate was 100 percent. All participants used mobile phones while at work, and also for hospital-related work. For 98.3 percent the mobile phone was their main mode of communication while in the hospital. Sixty-two percent (n = 37) made 6-10 calls daily purely for work-related business, and this comprised of ≥ 80 percent of their daily usage of mobile phones. For 98 percent of participants, most phone calls were work-related. Regarding reasons for using mobile phones, all reported that using mobile phone is quicker for communication. Mobile phone usage is very common among the medical personnel, and this is regarded as a more efficient means of communication for mobile staff than the hospital paging system.

Is There a Role for Oncotype Dx Testing in Invasive Lobular Carcinoma?

2015-01-01

Oncotype Dx Breast Cancer Assay is a 21-gene assay used in estrogen receptor (ER)-positive breast cancer to predict benefit from chemotherapy (CT). Tumors are placed into one of three risk categories based on their recurrence score (RS). This paper explores the impact of tumor histopathologic features and Oncotype Dx RS on the treatment plan for invasive lobular carcinoma (ILC). Invasive lobular carcinoma cases submitted for Oncotype Dx testing were identified from a clinical data base. The histopathologic and immunohistochemical features and RS subcategory of each tumor, and treatment regimen and medical oncologic assessments of each patient were reviewed. A total of 135 cases of ILC had RS testing, which represented 15% of all ILC diagnosed at the institution over the time period. 80% of ILC was of the classical subtype and all tumors were ER positive and human epidermal growth factor receptor 2 (HER-2) negative by immunohistochemistry. Sixty three percent of cases were low risk (LR), 35.5% were intermediate risk (IR) and 1.5% were high risk (HR). Both HR cases were pleomorphic ILC. Sixty eight percent of classical ILC had a LR score, while 70% of pleomorphic ILC had an IR score. Patients in the IR category were significantly more likely to undergo CT than patients in the LR category (54% versus 18%; p < 0.0001). In the LR category, those undergoing CT were significantly younger and more likely to have positive lymph nodes (p < 0.05). Qualitative analysis of medical oncologic assessments showed that RS played a role in decision-making on CT in 74% of cases overall. At our institution, Oncotype Dx RS currently plays a role in the management of a proportion of ILC and impacts on treatment decisions. © 2015 Wiley Periodicals, Inc.

Distinguishing pannus and thrombus in patients with prosthetic valve dysfunction is essential for the selection of proper treatment. We have investigated the utility of 64-slice multidetector computed tomography (MDCT) in distinguishing between pannus and thrombus, the latter amenable to thrombolysis. Sixty-two (23 men, mean age 44±14 years) patients with suspected mechanical prosthetic valve dysfunction assessed by transesophageal echocardiography were included in this prospective observational trial. Subsequently, MDCT was performed before any treatment was started. Periprosthetic masses were detected by MDCT in 46 patients, and their attenuation values were measured as Hounsfield Units (HU). Patients underwent thrombolysis unless contraindicated, and those with a contraindication or failed thrombolysis underwent surgery. A mass which was completely lysed or surgically detected as a clot was classified as thrombus, whereas a mass which was surgically detected as tissue overgrowth was classified as pannus. A definitive diagnosis could be achieved in 37 patients with 39 MDCT masses (22 thrombus and 17 pannus). The mean attenuation value of 22 thrombotic masses was significantly lower than that in 17 pannus (87±59 versus 322±122; Ppannus from thrombus. Complete lysis was more common for masses with HUpannus overgrowth, whereas a lower value is associated with thrombus formation. A higher attenuation (HU>90) is associated with reduced lysis rates. © 2015 American Heart Association, Inc.

Demura, Shinichi; Yamaji, Shunsuke; Kitabayashi, Tamotsu

2006-08-01

There is a large residual volume (RV) error when assessing percent body fat by means of hydrostatic weighing. It has generally been measured before hydrostatic weighing. However, an individual's maximal exhalations on land and in the water may not be identical. The aims of this study were to compare residual volumes and vital capacities on land and when immersed to the neck in water, and to examine the influence of the measurement error on percent body fat. The participants were 20 healthy Japanese males and 20 healthy Japanese females. To assess the influence of the RV error on percent body fat in both conditions and to evaluate the cross-validity of the prediction equation, another 20 males and 20 females were measured using hydrostatic weighing. Residual volume was measured on land and in the water using a nitrogen wash-out technique based on an open-circuit approach. In water, residual volume was measured with the participant sitting on a chair while the whole body, except the head, was submerged . The trial-to-trial reliabilities of residual volume in both conditions were very good (intraclass correlation coefficient > 0.98). Although residual volume measured under the two conditions did not agree completely, they showed a high correlation (males: 0.880; females: 0.853; P body fat computed using residual volume measured in both conditions was very good for both sexes (males: r = 0.902; females: r = 0.869, P body fat: -3.4 to 2.2% for males; -6.3 to 4.4% for females). We conclude that if these errors are of no importance, residual volume measured on land can be used when assessing body composition.

The causative agent spectrum and resistance patterns of urinary tract infections in children are affected by many factors. To demonstrate antibiotic resistance in urinary tract infections and changing ratio in antibiotic resistance by years. Retrospective cross-sectional study. We analysed antibiotic resistance patterns of isolated Gram (-) bacteria during the years 2011-2014 (study period 2) in children with urinary tract infections. We compared these findings with data collected in the same centre in 2001-2003 (study period 1). Four hundred and sixty-five uncomplicated community-acquired Gram (-) urinary tract infections were analysed from 2001-2003 and 400 from 2011-2014. Sixty-one percent of patients were female (1.5 girls : 1 boy). The mean age of children included in the study was 3 years and 9 months. Escherichia coli was the predominant bacteria isolated during both periods of the study (60% in study period 1 and 73% in study period 2). Bacteria other than E. coli demonstrated a higher level of resistance to all of the antimicrobials except trimethoprim-sulfamethoxazole than E. coli bacteria during the years 2011-2014. In our study, we found increasing resistance trends of urinary pathogens for cefixime (from 1% to 15%, pUrinary pathogens showed a decreasing trend for nitrofurantoin (from 17% to 7%, p=0.0001). No significant trends were detected for ampicillin (from 69% to 71%), amoxicillin-clavulanate (from 44% to 43%), cefazolin (from 39% to 32%), trimethoprim-sulfamethoxazole (from 32% to 31%), cefuroxime (from 21% to 18%) and ceftriaxone (from 10% to 14%) between the two periods (p>0.05). In childhood urinary tract infections, antibiotic resistance should be evaluated periodically and empiric antimicrobial therapy should be decided according to antibiotic sensitivity results.

Wunsch, Kathrin; Kasten, Nadine; Fuchs, Reinhard

2017-01-01

The stress-buffering hypothesis postulates that physical activity and exercise can buffer the negative effects of (academic) stress on health. It still remains an open question whether students, who regularly engage in physical activity and exercise within their academic examination period, can successfully diminish these negative effects. Sixty-four subjects participated in this study and completed a total of five surveys, with T1 at the end of the semester break (baseline) and T2-T5 being presented every Friday in the last 4 weeks of the semester (examination period). They were asked to answer questions about their activity level, sleep quality, well-being and affect. Hierarchical linear models showed significant dependencies on time for all dependent measures. The expansion of the model for exercise also showed significant main effects of this predictor on well-being and positive affect (PA) and negative affect. Moreover, significant interactions with time for sleep quality and PA were found. Results suggest that physical activity and exercise in the academic examination period may be able to buffer the negative effects of stress on health-related outcomes. Therefore, activity levels should be maintained in times of high stress to prevent negative effects on sleep, well-being and affect in students.

Induced prismatic effects due to poorly fitting spectacle frames

toms were reported by 50% of subjects experiencing base-out, 0% base-in and 47% vertical induced prismatic effects.  However, no correlation existed between those subjects experiencing induced prism and symptoms reported.  Prism adaptation may account for some participants being asymptomatic.  Sixty three percent of subjects were not aware of the importance of properly fitted spectacle frames.  Proper optical dispensing with associated patient education is necessary to achieve optimal optical benefits of spectacles and careful attention should be given to this aspect by practitioners.  It is recommended that patients return periodically to their optometrists to have the frame alignment assessed and the fit modified if necessary.

Although regular participation in physical activity (PA) has health benefits across the life span, the proportion of people doing sufficient activity for these benefits decreases with age. The aim of this study was to identify motivating factors and context preferences for PA in people in their sixties, and to examine gender differences in these factors. Data were used from people aged 60-67 years who responded to a mail survey in Brisbane, Australia, in 2009. Respondents indicated their agreement/disagreement with seven PA motivators and 14 PA context preferences. Data were analyzed using multi-level multinomial logistic regression, adjusted for sociodemographic and health variables, and PA level. Of the 1845 respondents, 59% was female. Based on self-reported PA, one in three respondents (35%) did not meet the PA guidelines of at least 150 min of moderate intensity PA per week. The three leading motivating factors for both women and men were to prevent health problems, to feel good and to lose weight. Women were more likely than men to be motivated by improving appearance (OR 2.93, 95%CI 2.07-4.15), spending time with others (1.76, 1.31-2.37), meeting friends (1.76, 1.31-2.36) or losing weight (1.74, 1.12-2.71). The three leading context preferences for both women and men were for activities close to home, at low cost and that could be done alone. Women were more likely than men to prefer activities that are with people of the same sex (OR 4.67, 95%CI 3.14-6.94), supervised (2.79, 1.94-4.02), with people the same age (2.00, 1.43-2.78) and at a fixed time (1.42, 1.06-1.91). Women were less likely than men to prefer activities that are competitive (OR 0.32, 95%CI 0.22-0.46), are vigorous (0.33, 0.24-0.47), require skill and practice (0.40, 0.29-0.55) and done outdoors (0.51, 0.30-0.86). Although there was overlap in motivating factors and context preferences for PA in women and men aged 60-67 years, there were also marked gender differences. These results

  The long-term patient satisfaction and safety of nightguard vital bleaching (NGVB) requires further evaluation.   The purpose of this study was to evaluate patients' satisfaction and identify side effects of NGVB up to 17 years post-treatment.   Thirty-one participants who had completed previous NGVB studies using 10% carbamide peroxide were contacted at least 10 years post-treatment (range 10-17 years, average 12.3 years). Participants reported shade satisfaction (very satisfied [VS], partially satisfied [PS], or not satisfied [NS]) as well as potential complications. Participants had teeth # 6 to 11 examined for tooth vitality, gingival inflammation (Löe's Gingival Index [GI]), and radiographically for external cervical resorption (ECR).   All of the participants had successful lightening of their teeth. Sixty-one percent (19) had not retreated their teeth. Of those who had not retreated their teeth and who responded to the question of whitening satisfaction, 31% (4/13) were VS, 54% (7/13) were PS, and 15% (2/13) were NS with their current shade. Of those who had retreated their teeth, all were VS or PS. Ninety-one percent of the examined teeth had GI = 0 (normal), 7% had GI = 1 (mild inflammation), and 2% had GI = 2 (moderate inflammation). Sixty-nine percent of teeth tested responded to a cold stimulus. Radiographs did not detect ECR or apical lesions. No participant reported having a gingival biopsy post-treatment, and 87% would whiten again.   Patient satisfaction with NGVB may last as long as 12.3 years in average (range 10-17 years) post-treatment. GI and ECR findings were considered within the normal expectations for the sample studied, suggesting minimal clinical post-NGVB side effects up to 17 years. Nightguard vital bleaching provides patient satisfaction with minimal side effects up to 17 years post-treatment. © 2011 Wiley Periodicals, Inc.

Ito, Hiromu; Kakishima, Satoshi; Uehara, Takashi; Morita, Satoru; Koyama, Takuya; Sota, Teiji; Cooley, John R; Yoshimura, Jin

2015-09-14

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

To characterise Haemophilus influenzae type b (Hib) invasive disease in the era of Hib vaccination, in children of the greater Auckland region of New Zealand. Identification of sterile site culture positive Hib via the Auckland hospital laboratories databases and national laboratory surveillance database in the time period; 1995 to 2009. There were a total of 26 cases in the Auckland Region. Over the 15-year period, the annual incidence of invasive Hib disease was 0.61 per 100,000 (95% CI: 0.4-0.9) for children aged under 15 years and 1.65 per 100,000 (95% CI: 1.1-2.5) for children aged under 5 years. Ninety-two percent were under 5 years and 54% were under 1 year. Sixty percent of the children were of Maori and Pacific ethnicity. The predominant diagnosis was meningitis, accounting for 15 cases (60%). There were no fatalities. Forty-eight percent of affected children were completely unimmunised with the Hib vaccine which has been fully funded on the National Immunisation Schedule since 1994. Since the introduction of the Hib vaccine, the disease rates have greatly reduced in the Auckland region. Although ethnic disparities have improved amongst the cases that occur, immunisation rates in cases are low and infants remain most at risk. Current emphasis on intensifying immunisation programmes to achieve higher vaccination rates and timeliness of delivery will help in efforts to achieve elimination of the disease in New Zealand.

The preferred treatment of hyperthyroidism remains controversial. Most of this data is derived from large, university-based medical centers. We report here our experience with treatment of hyperthyroidism in a community setting. This involves 144 patients with hyperthyroidism who were seen over a 10 year period at Michigan State University Clinical Center and were treated in the community hospitals and private physicians' offices, and by community surgeons. Follow-up data were available on 119 of these patients; 105 of them were hyperthyroid because of Graves' disease and multinodular goiter. Patients were encouraged to make their own decisions regarding choice of therapy, as independently as possible. Sixty-five percent of these patients were treated by 131I, 18% by antithyroid drugs, and 17% by surgery. The mean follow-up period was 2.5 years (range 2 months to 19 years). Hyperthyroidism was controlled in 84% of the patients treated by 131I and 83% of the patients treated by surgery. Forty percent of the patients treated by 131I and 33% treated by surgery became hypothyroid. Fifty percent of the patients achieved remission when treated by antithyroid drugs alone. Our results indicate that when patients are encouraged to make their own decisions regarding the treatment of hyperthyroidism, their choices are similar to those of the thyroidologists. Secondly, the results obtained with different modalities of treatment for hyperthyroidism in a community setting are similar to those obtained in university medical centers

Sillup, George P; Klimberg, Ronald K

2011-01-01

The objective of this study was to examine the relative efficacy of two different methodologies for auditing self-funded medical claim expenses: 100-percent-of-claims auditing versus random-sampling auditing. Multiple data sets of claim errors or 'exceptions' from two Fortune-100 corporations were analysed and compared to 100 simulated audits of 300- and 400-claim random samples. Random-sample simulations failed to identify a significant number and amount of the errors that ranged from $200,000 to $750,000. These results suggest that health plan expenses of corporations could be significantly reduced if they audited 100% of claims and embraced a zero-defect approach.

This study evaluated in vitro the influence of an eugenol-based sealer (EndoFill) on the retention of stainless steel prefabricated posts cemented with zinc phosphate and resin-based (Panavia F) cements after different periods of root canal obturation, using the pull-out test. Sixty upper canines were decoronated and the roots were embedded in resin blocks. The specimens were distributed into 3 groups, according to the period elapsed between canal obturation and post cementation: Group I - immediately; Group II - 72 h and Group III - 4 months. The groups were subdivided according to the type of cement used for post cementation: A - zinc phosphate and B - Panavia F. Following the experimental periods, specimens were subjected to pullout test in an Instron machine with application of tensile force at a crosshead speed of 0.5 mm/min until post dislodgement. The maximum forces required for post removal were recorded (kN) and means were subjected to statistical analysis by 2-way ANOVA and Tukey-Kramer test (alpha=0.001) There were statistically significant differences (pcemented with zinc phosphate cement (0.2112 kN) and Panavia F (0.0501 kN). However, no statistically significant differences (p>0.05) were found between the three post cementation periods, regardless of the cement. It was concluded that the eugenol-based sealer influenced the tensile strength of the posts cemented with the resin cement, but had no influence on the time waited between root canal obturation and post space preparation/post cementation.

2007-01-01

Full Text Available Abstract Background The relationship between BMI and leptin has been studied extensively in the past, but previous reports in postmenopausal women have not been conducted under carefully controlled dietary conditions of weight maintenance using precise measures of body fat distribution. The aim of the present study was to examine the association between serum leptin concentration and adiposity as estimated by BMI and dual energy x-ray absorptiometry (DEXA measures (percent body fat, central and peripheral fat, and lean mass in postmenopausal women. Methods This study was conducted as a cross-sectional analysis within the control segment of a randomized, crossover trial in which postmenopausal women (n = 51 consumed 0 (control, 15 (one drink, and 30 (two drinks g alcohol (ethanol/d for 8 weeks as part of a controlled diet. BMIs were determined and DEXA scans were administered to the women during the 0 g alcohol treatment, and a blood sample was collected at baseline and week 8 of each study period for leptin analysis. Results and discussion In multivariate analysis, women who were overweight (BMI > 25 to ≤ 30 kg/m2 had a 2-fold increase, and obese women (BMI > 30 kg/m2 had more than a 3-fold increase in serum leptin concentrations compared to normal weight (BMI ≤25 kg/m2 women. When the models for the different measures of adiposity were assessed by multiple R2, models which included percent body fat explained the highest proportion (approximately 80% of the serum leptin variance. Conclusion Under carefully controlled dietary conditions, we confirm that higher levels of adiposity were associated with higher concentrations of serum leptin. It appears that percent body fat in postmenopausal women may be the best adiposity-related predictor of serum leptin.

Energy Technology Data Exchange (ETDEWEB)

Okazaki, Michiharu; Ogata, Katsumi; Inoue, Shouhei (Miyazaki Medical Coll., Kiyotake (Japan))

1989-01-01

A review was made on 412 cases of postirradiation skin malignancies reported in Japan up to March 1988. The ratio of male to female was 2:1. Histologically, squamous cell carcinoma occupied 60% of all cases. The incidence of sarcoma has recently been increased. Sixty percent of all skin malignancies resulted from irradiation for benign diseases. Radiotherapy has recently become the treatment of choice for malignancy. The incidence of malignancy resulting from occupational exposure has remained unchanged. The latency period before the development of radiation-induced malignancy varied in the following order with cause or primary disease: occupation>benign tumors>malignant tumors; and it varied with histology in the following order: basal cell epithelioma>squamous cell carcinoma>sarcoma. Malignant tumors treated with large doses of high energy photon beams were likely to develop sarcomas in a relatively short latency period of time. (N.K.).

OBJECTIVES: Our objective was to document the pattern of mobile phone usage by medical staff in a hospital setting, and to explore any perceived benefits (such as improved communications) associated with mobile phones. METHODS: This cross-sectional survey was conducted in Waterford Regional Hospital, Ireland, where bleep is the official system of communication. All non-consultant hospital doctors, of medical disciplines only, were asked to participate. The questionnaire was designed to explore the pattern and different aspects of mobile phone usage. RESULTS: At the time of study, there were sixty medical junior doctors, and the response rate was 100 percent. All participants used mobile phones while at work, and also for hospital-related work. For 98.3 percent the mobile phone was their main mode of communication while in the hospital. Sixty-two percent (n = 37) made 6-10 calls daily purely for work-related business, and this comprised of >\\/= 80 percent of their daily usage of mobile phones. For 98 percent of participants, most phone calls were work-related. Regarding reasons for using mobile phones, all reported that using mobile phone is quicker for communication.Conclusions: Mobile phone usage is very common among the medical personnel, and this is regarded as a more efficient means of communication for mobile staff than the hospital paging system.

[Purpose] The purpose of this study was to investigate factors influencing the period from surgery to discharge in patients with femoral trochanteric fractures. [Subjects and Methods] Sixty patients with femoral trochanteric fractures were investigated retrospectively. Based on the mean period from surgery to discharge (85.6 ± 26.6 days), the patients were divided into two groups: an under-85-day group (range, 29–78 days) and an over-85-day group (87–128 days). Age, gender, fracture type, presence of lesser trochanteric displacement, discharge destination, and walking ability were investigated. The relationship between these factors and the period from surgery to discharge was analyzed with logistic regression analysis. [Results] Age and lesser trochanteric displacement were significantly higher in the over-85-day group, and walking ability before fracture and at discharge were significantly lower in the over-85-day group. Logistic regression analysis showed that lesser trochanteric displacement and age were predictors of the length from surgery to discharge. Lesser trochanteric displacement were observed in 87.5% of these. Immediate displacement after surgery occurred in 57.8% of lesser trochanteric fractures, while 26.3% displaced 1 to 3 weeks after surgery. [Conclusion] This study revealed that lesser trochanteric displacement, higher age, and lower walking ability before fracture and at discharge were associated with longer hospitalizations in patients with femoral trochanteric fractures. Lesser trochanteric displacement were observed in 87.5% of lesser trochanteric fractures. These displacements occurred within 3 weeks after surgery in 84.1% of cases. PMID:29200639

Full Text Available Abstract Background Although regular participation in physical activity (PA has health benefits across the life span, the proportion of people doing sufficient activity for these benefits decreases with age. The aim of this study was to identify motivating factors and context preferences for PA in people in their sixties, and to examine gender differences in these factors. Methods Data were used from people aged 60–67 years who responded to a mail survey in Brisbane, Australia, in 2009. Respondents indicated their agreement/disagreement with seven PA motivators and 14 PA context preferences. Data were analyzed using multi-level multinomial logistic regression, adjusted for sociodemographic and health variables, and PA level. Results Of the 1845 respondents, 59% was female. Based on self-reported PA, one in three respondents (35% did not meet the PA guidelines of at least 150 min of moderate intensity PA per week. The three leading motivating factors for both women and men were to prevent health problems, to feel good and to lose weight. Women were more likely than men to be motivated by improving appearance (OR 2.93, 95%CI 2.07–4.15, spending time with others (1.76, 1.31–2.37, meeting friends (1.76, 1.31–2.36 or losing weight (1.74, 1.12–2.71. The three leading context preferences for both women and men were for activities close to home, at low cost and that could be done alone. Women were more likely than men to prefer activities that are with people of the same sex (OR 4.67, 95%CI 3.14–6.94, supervised (2.79, 1.94–4.02, with people the same age (2.00, 1.43–2.78 and at a fixed time (1.42, 1.06–1.91. Women were less likely than men to prefer activities that are competitive (OR 0.32, 95%CI 0.22–0.46, are vigorous (0.33, 0.24–0.47, require skill and practice (0.40, 0.29–0.55 and done outdoors (0.51, 0.30–0.86. Conclusion Although there was overlap in motivating factors and context preferences for PA in women and men

The polychaetous annelid Neanthes acuminata complex has a widespread distribution, with the California population referred to as N. arenaceodentata. The reproductive pattern in this complex is unique, in that the female reproduces once and then dies, whereas the male can reproduce up to nine times. The male incubates the embryos until the larvae leave the male’s tube 21–28 days later and commences feeding. Reproductive success and protein expression patterns were measured over the nine reproductive periods. The percent success of the male in producing juveniles increased during the first three reproductive periods and then decreased, but the number of juveniles produced was similar through all nine periods. iTRAQ based quantitative proteomics were used to analyze the dynamics of protein expression patterns. The expression patterns of several proteins were found to be altered. The abundant expression of muscular and contractile proteins may have affected body weight and reproductive success. Sperm have never been observed; fertilization occurs within the parent’s tube. Proteins associated with sperm maturation and fertilization were identified, including ATPase, clathrin, peroxiredoxins and enolase, which may provide clues to the molecular mechanisms enabling males to reproduce multiple times.

The purpose of this study was to determine the effectiveness of a baking soda/hydrogen peroxide dentifrice, Mentadent, and a 0.12 percent chlorhexidine gluconate mouthrinse, Peridex, in reducing gingival bleeding. Forty subjects were divided into three groups; the baking soda group, the chlorhexidine group and the control group. All groups received oral hygiene instruction and brushed and flossed three times per day. Bleeding point scores were evaluated at baseline and at five weeks. The baking soda/hydrogen peroxide group used the supplied dentifrice as their sole toothpaste. The 0.12 percent chlorhexidine group used the mouthrinse twice per day. The control group performed oral hygiene as instructed. At five weeks, the 0.12 percent chlorhexidine mouthrinse significantly reduced gingival bleeding. The dentifrice and control groups revealed no statistically significant reductions. The results indicate that the 0.12 percent chlorhexidine mouthrinse is useful in improving oral health, whereas the baking soda/hydrogen peroxide dentifrice offered no advantages to conventional oral hygiene.

periods to show how precipitation deficits in Oklahoma varied by region. The nine climate divisions in Oklahoma had precipitation in water year 2011 ranging from 43 to 76 percent of normal annual precipitation, with the Northeast Climate Division having the closest to normal precipitation and the Southwest Climate Division having the greatest percentage of annual deficit. Based on precipitation amounts, water year 2011 ranked as the second driest of the 1925–2011 period, being exceeded only in one year of the 1952 to 1956 drought period. Regional streamflow patterns for water year 2011 indicate that streamflow in the Arkansas-White-Red water resources region, which includes all of Oklahoma, was relatively large, being only the 26th lowest since 1930, primarily because of normal or above-normal streamflow in the northern part of the region. Twelve long-term streamflow-gaging stations with periods of record ranging from 67 to 83 years were selected to show how streamflow deficits varied by region in Oklahoma. Statewide, streamflow in water year 2011 was greater than streamflows measured in years during the drought periods of 1929–41, 1952–56, 1961–72, and 1976–81. The hydrologic drought worsened going from the northeast toward the southwest in Oklahoma, ranging from 140 percent (above normal streamflow) in the northeast, to 13 percent of normal streamflow in southwestern Oklahoma. The relatively low streamflow in 2011 resulted in 83.3 percent of the statewide conservation storage being available at the end of the water year in major reservoirs, similar to conservation storage in the preceding severe drought year of 2006. The ranking of streamflow as the 16th smallest for the 1925–2011 period, despite precipitation being ranked the 2d smallest, may have been caused, in part, by the relatively large streamflow in northeastern Oklahoma during water year 2011.

Geographic variation in avian incubation periods and parental influences on embryonic temperature.

Theory predicts shorter embryonic periods in species with greater embryo mortality risk and smaller body size. Field studies of 80 passerine species on three continents yielded data that largely conflicted with theory; incubation (embryonic) periods were longer rather than shorter in smaller species, and egg (embryo) mortality risk explained some variation within regions, but did not explain larger differences in incubation periods among geographic regions. Incubation behavior of parents seems to explain these discrepancies. Bird embryos are effectively ectothermic and depend on warmth provided by parents sitting on the eggs to attain proper temperatures for development. Parents of smaller species, plus tropical and southern hemisphere species, commonly exhibited lower nest attentiveness (percent of time spent on the nest incubating) than larger and northern hemisphere species. Lower nest attentiveness produced cooler minimum and average embryonic temperatures that were correlated with longer incubation periods independent of nest predation risk or body size. We experimentally tested this correlation by swapping eggs of species with cool incubation temperatures with eggs of species with warm incubation temperatures and similar egg mass. Incubation periods changed (shortened or lengthened) as expected and verified the importance of egg temperature on development rate. Slower development resulting from cooler temperatures may simply be a cost imposed on embryos by parents and may not enhance offspring quality. At the same time, incubation periods of transferred eggs did not match host species and reflect intrinsic differences among species that may result from nest predation and other selection pressures. Thus, geographic variation in embryonic development may reflect more complex interactions than previously recognized.

Percent relative cumulative frequency analysis in indirect calorimetry: application to studies of transgenic mice.

Science.gov (United States)

Riachi, Marc; Himms-Hagen, Jean; Harper, Mary-Ellen

2004-12-01

Indirect calorimetry is commonly used in research and clinical settings to assess characteristics of energy expenditure. Respiration chambers in indirect calorimetry allow measurements over long periods of time (e.g., hours to days) and thus the collection of large sets of data. Current methods of data analysis usually involve the extraction of only a selected small proportion of data, most commonly the data that reflects resting metabolic rate. Here, we describe a simple quantitative approach for the analysis of large data sets that is capable of detecting small differences in energy metabolism. We refer to it as the percent relative cumulative frequency (PRCF) approach and have applied it to the study of uncoupling protein-1 (UCP1) deficient and control mice. The approach involves sorting data in ascending order, calculating their cumulative frequency, and expressing the frequencies in the form of percentile curves. Results demonstrate the sensitivity of the PRCF approach for analyses of oxygen consumption (.VO2) as well as respiratory exchange ratio data. Statistical comparisons of PRCF curves are based on the 50th percentile values and curve slopes (H values). The application of the PRCF approach revealed that energy expenditure in UCP1-deficient mice housed and studied at room temperature (24 degrees C) is on average 10% lower (p lower environmental temperature, there were no differences in .VO2 between groups. The latter is likely due to augmented shivering thermogenesis in UCP1-deficient mice compared with controls. With the increased availability of murine models of metabolic disease, indirect calorimetry is increasingly used, and the PRCF approach provides a novel and powerful means for data analysis.

Full Text Available Background. ACC-HRS Guidelines for Cardiac Resynchronization Therapy ICD implantation (CRT-D do not include patients with advanced nonambulatory NYHA class-four CHF due to an expectation of limited survival. There is little data available from these large multicenter randomized studies to support or refute this claim. Purpose. We evaluated the outcomes of patients with advanced nonambulatory NYHA class-four CHF who received CRT-D devices as an attempt to improve the clinical status and promote hospital discharge. Methods. Sixteen (of our six hundred and seventy CRT-D patients were classified as advanced nonambulatory NYHA Class four inotrope/vasodilator/diuretic-dependent patients. These patients were analyzed retrospectively for weaning success to oral medications, hospital discharge, hemodynamic stability, and survival over eighteen months. Results. Thirteen of sixteen patients were discharged to home within two weeks of implantation.

Interstitial lung disease is common in patients with sickle cell anemia (SCA). Fibrocytes are circulating cells implicated in the pathogenesis of pulmonary fibrosis and airway remodeling in asthma. In this study, we tested the hypotheses that fibrocyte levels are: (1) increased in children with SCA compared to healthy controls, and (2) associated with pulmonary disease. Cross-sectional cohort study of children with SCA who participated in the Sleep Asthma Cohort Study. Fibrocyte levels were obtained from 45 children with SCA and 24 controls. Mean age of SCA cases was 14 years and 53% were female. In children with SCA, levels of circulating fibrocytes were greater than controls (P < 0.01). The fibrocytes expressed a hierarchy of chemokine receptors, with CXCR4 expressed on the majority of cells and CCR2 and CCR7 expressed on a smaller subset. Almost half of fibrocytes demonstrated α-smooth muscle actin activation. Increased fibrocyte levels were associated with a higher reticulocyte count (P = 0.03) and older age (P = 0.048) in children with SCA. However, children with increased levels of fibrocytes were not more likely to have asthma or lower percent predicted forced expiratory volume in 1 sec/forced vital capacity (FEV1 /FVC) or FEV1 than those with lower fibrocyte levels. Higher levels of fibrocytes in children with SCA compared to controls may be due to hemolysis. Longitudinal studies may be able to better assess the relationship between fibrocyte level and pulmonary dysfunction. © 2015 Wiley Periodicals, Inc.

The use of rigorous scientific methods has contributed towards developing scientific articles of excellent methodological quality. This has made it possible to promote their citation and increase the impact factor. Brazilian periodicals have had to adapt to certain quality standards demanded by these indexing organizations, such as the content and the number of original articles published in each issue. This study aimed to evaluate the methodological adequacy of two Brazilian periodicals within the field of cardiology that are indexed in several databases and freely accessible through the Scientific Electronic Library Online (SciELO), and which are now indexed by the Web of Science (Institute for Scientific Information, ISI). Descriptive study at Brazilian Cochrane Center. All the published articles were evaluated according to merit assessment (content) and form assessment (performance). Ninety-six percent of the articles analyzed presented study designs that were adequate for answering the objectives. These two Brazilian periodicals within the field of cardiology published methodologically adequate articles, since they followed the quality standards. Thus, these periodicals can be considered both for consultation and as vehicles for publishing future articles. For further analyses, it is essential to apply other indicators of scientific activity such as bibliometrics, which evaluates quantitative aspects of the production, dissemination and use of information, and scientometrics, which is also concerned with the development of science policies, within which it is often superimposed on bibliometrics.

In order to investigate the tumor affinity radioisotopes, chromium (51Cr), molybdenum (99Mo), tungsten (181W), selenium (75Se) and tellurium (127mTe)--the elements of group VI in the periodic table--were examined, using the rats which were subcutaneously transplanted with Yoshida sarcoma. Seven preprarations, sodium chromate (Na251CrO4), chromium chloride (51CrCl3), normal ammonium molybdate ((NH4)299MoO7), sodium tungstate (Na2181WO4), sodium selenate (Na275SeO4), sodium selenite (Na275SeO3) and tellurous acid (H2127mTeO3) were injected intravenously to each group of tumor bearing rats. These rats were sacrificed at various periods after injection of each preparation: 3 hours, 24 hours and 48 hours in all preparations. The radioactivities of the tumor, blood, muscle, liver, kidney and spleen were measured by a well-type scintillation counter, and retention values (in every tissue including the tumor) were calculated in percent of administered dose per g-tissue weight. All of seven preparations did not have any affinity for malignant tumor. Na251CrO4 and H2127mTeO3 had some affinity for the kidneys, and Na275SeO3 had some affinity for the liver. Na2181WO4 and (NH4)299MoO4 disappeared very rapidly from the blood and soft tissue, and about seventy-five percent of radioactivity was excreted in urine within first 3 hours.

White, R.I. Jr.; Rizer, D.M.; Shuman, K.; White, E.J.; Adams, P.; Doyle, K.; Kinnison, M.

1987-01-01

During a 5-year period (1982-1987), 376 patients were admitted to an interventional radiology service where they were managed by the senior physician and interventional radiology fellows. Sixty-eight percent of patients were admitted for angioplasty and 32% for elective embolotherapy/diagnostic angiography. A one-half-day, twice weekly interventional radiology clinic and employment of a physician's assistant who performed preadmission history and physicals and wrote orders accounted, in part, for a decrease in hospital stay length from 3.74 days (1982-1983) to 2.41 days (1986-1987). The authors conclude that use of the clinic and the physician's assistant streamlines patient flow and the admitting process and is partially responsible for a decreased length of stay for patients admitted to an interventional radiology service

We have annually held an open experiment of PIXE analysis since 1996 to get people's understanding on nuclear technology and radiation science. Up to the present, more than 270 participants joined and enjoyed the open experiments. This year, we demonstrated performance of a submilli-PIXE camera and had sixty-nine participants in the open experiment of PIXE. Elemental spatial distribution images gave deep impression to the participants. Half of the participants were high school students since the open experiment of PIXE was held during the period of open campus of Tohoku University. About ten percents of the participants were junior high school students. Our open experiment of PIXE was very effective to arouse public interest in radiation science and nuclear technology.

 Running speed during training and percent body fat predict race time in recreational male marathoners

Directory of Open Access Journals (Sweden)

Barandun U

2012-07-01

Full Text Available  Background: Recent studies have shown that personal best marathon time is a strong predictor of race time in male ultramarathoners. We aimed to determine variables predictive of marathon race time in recreational male marathoners by using the same characteristics of anthropometry and training as used for ultramarathoners.Methods: Anthropometric and training characteristics of 126 recreational male marathoners were bivariately and multivariately related to marathon race times.Results: After multivariate regression, running speed of the training units (β=-0.52, P<0.0001 and percent body fat (β=0.27, P <0.0001 were the two variables most strongly correlated with marathon race times. Marathon race time for recreational male runners may be estimated to some extent by using the following equation (r2 = 0.44: race time (minutes = 326.3 + 2.394 × (percent body fat, % – 12.06 × (speed in training, km/hours. Running speed during training sessions correlated with prerace percent body fat (r=0.33, P=0.0002. The model including anthropometric and training variables explained 44% of the variance of marathon race times, whereas running speed during training sessions alone explained 40%. Thus, training speed was more predictive of marathon performance times than anthropometric characteristics.Conclusion: The present results suggest that low body fat and running speed during training close to race pace (about 11 km/hour are two key factors for a fast marathon race time in recreational male marathoner runners.Keywords: body fat, skinfold thickness, anthropometry, endurance, athlete

Outlook for Global Nuclear Power: Energy, Electricity and Nuclear Power Estimates for the Period up to 2050

International Nuclear Information System (INIS)

Gritsevskyi, A.

2016-01-01

Nuclear power's global expansion is projected to continue in the coming decades - albeit at a slowing pace - amid challenges including low fossil fuel prices, a sluggish world economy and the legacy of Japan's Fukushima Daiichi accident. Each year, the IAEA publishes projections of the world's nuclear power generating capacity in Energy, Electricity and Nuclear Power Estimates for the Period up to 2050, now in its 35th edition.The latest projections point to slower growth in nuclear power, in keeping with the trend since the 2011 Fukushima Daiichi accident. The world's nuclear power generating capacity is projected to expand by 2.4 percent by 2030, according to the low projections, compared with 7.7 percent estimated in 2014. In the high case, generating capacity is estimated to grow by 68 percent by 2030, versus 88 percent forecast last year. Uncertainty related to energy policy, license renewals, shutdowns and future constructions accounts for the wide range.The estimates also factor in the likely future retirement of many of the world's 438 nuclear reactors currently in operation, more than half of which are over 30 years old. Despite the need to replace scores of retiring reactors, nuclear power is still set to maintain - and possibly increase - its role in the world's low-carbon energy mix. It's important to understand that these projections, while carefully derived, are not predictions.The estimates should be viewed as very general growth trends, whose validity must be constantly subjected to critical review.(author).

Geographic variation in avian incubation periods and parental influences on embryonic temperature

Martin, T.E.; Auer, S.K.; Bassar, R.D.; Niklison, Alina M.; Lloyd, P.

Theory predicts shorter embryonic periods in species with greater embryo mortality risk and smaller body size. Field studies of 80 passerine species on three continents yielded data that largely conflicted with theory; incubation (embryonic) periods were longer rather than shorter in smaller species, and egg (embryo) mortality risk explained some variation within regions, but did not explain larger differences in incubation periods among geographic regions. Incubation behavior of parents seems to explain these discrepancies. Bird embryos are effectively ectothermic and depend on warmth provided by parents sitting on the eggs to attain proper temperatures for development. Parents of smaller species, plus tropical and southern hemisphere species, commonly exhibited lower nest attentiveness (percent of time spent on the nest incubating) than larger and northern hemisphere species. Lower nest attentiveness produced cooler minimum and average embryonic temperatures that were correlated with longer incubation periods independent of nest predation risk or body size. We experimentally tested this correlation by swapping eggs of species with cool incubation temperatures with eggs of species with warm incubation temperatures and similar egg mass. Incubation periods changed (shortened or lengthened) as expected and verified the importance of egg temperature on development rate. Slower development resulting from cooler temperatures may simply be a cost imposed on embryos by parents and may not enhance offspring quality. At the same time, incubation periods of transferred eggs did not match host species and reflect intrinsic differences among species that may result from nest predation and other selection pressures. Thus, geographic variation in embryonic development may reflect more complex interactions than previously recognized. ?? 2007 The Author(s).

Effect of the fluid core on changes in the length of day due to long period tides

Science.gov (United States)

Wahr, J. M.; Smith, M. L.; Sasao, T.

1981-01-01

The long period luni-solar tidal potential is known to cause periodic changes in the earth's rotation rate. It is found that the effect of a dissipationless fluid outer core is to reduce the amplitudes of these tidal perturbations by about 11 percent. When the fluid core effect is added to Agnew and Farrell's (1978) estimate of the effect of an equilibrium ocean, the result is in accord with observation. The effects of dissipative processes within the fluid core are also examined. Out-of-phase perturbations are found which could be as large as about 10 ms at 18.6 yr. It is concluded, however, that the poorly understood decade fluctuations in the earth's rotation rate will prohibit observation of this effect.

To observe the effects differences for polycystic ovary syndrome (PCOS) between periodic therapy of acupuncture and diane-35 and to explore its mechanism. Sixty patients were randomly assigned into an acupuncture group and a western medication group, 30 cases in each one, 29 patients finally included with one case dropping out respectively. In the acupuncture group, periodic therapy was mainly used at bilateral Sanyinjiao (SP 6), Dahe (KI 12), Guilai (ST 29), Guanyuan (CV 4), Zhongji (CV 3), with different acupoints in the postmenstrual, intermenstrual, premenstrual periods, once every other day, 3 times a week. EA (2 Hz/100 Hz) was used at bilateral Dahe (KI 12) and Guilai (ST 29). If treatment, FSH increased and LH, LH/FSH, T decreased in the two groups (all P medication group were better than those in the acupuncture group (both P medication group, diane-35 was prescribed orally for 21 days as a course, with 7 days at interval, one tablet a day. All the treatment was started on the fifth day of the menstrual circle, for continuously 3 months. The indexes were observed before and after treatment, including the menstrual circle, acne score, body mass index (BMI), serum follicle stimulating hormone (FSH), luteinizing hormone (LH), LH/FSH and testosterone (T). The effects of the two groups were compared. The total effective rate was 75.9% (22/29) in the acupuncture group, which was not significantly different from 79.3% (23/29) in the western medication group ( P >0.05). The menstrual cycles were shorter after treatment in the two groups (both P 0.05). After treatment,FSH increased and LH,LH/FSH,T decreased in the two groups (all P medication group were better than those in the acupuncture group (both P <0.05). Conclusion Periodic therapy of acupuncture is probably one of the effective methods for PCOS,which can improve patients' clinical symptoms,sex hormone level,and menstrual cycle.

We examined patients' experiences of patient safety and participation in promoting safe care during their most recent care period. A survey of patients (N = 175) revealed that treatment, medication, and device safety were mostly experienced as very good or excellent, but responses varied by age and experience. Patients ages 66-75 were most critical of treatment and medication safety. Device safety was rated the worst aspect of safety. Twenty percent of respondents had experienced errors at some time during their care. Patients who had experienced errors and those who were treated at inpatient wards versus a day surgery unit were most critical towards patient participation. Open and transparent error management involving patients is needed to promote treatment, medication, and especially device safety. © 2014 Wiley Periodicals, Inc.

This study characterizes the epidemiology of nonfatal pediatric firework-related injuries in the United States among children and adolescents by analyzing data from the National Electronic Injury Surveillance System from 1990 through 2014. During this 25-year period, an estimated 136 991 (95% CI = 113 574-160 408) children firework-related injuries. The annual injury rate decreased significantly by 30.4% during this period. Most of those injured were male (75.7%), mean patient age was 10.6 years, and 7.6% required hospital admission. The hands (30.0%) were the most commonly injured body region, followed by head and neck (22.2%), and eyes (21.5%). Sixty percent of injuries were burns. Injuries were most commonly associated with firecrackers (26.2%), aerial devices (16.3%), and sparklers (14.3%). Consumer fireworks pose a serious injury risk to pediatric users and bystanders, and families should be encouraged to attend public firework displays rather than use consumer fireworks.

Managerial ownership and corporate performance in Slovenian post-privatisation period

Marko Simoneti

2004-12-01

Full Text Available The Slovenian post-privatisation period has been characterised by a decline in the ownership by non-managerial owners (employees and state-controlled funds. On the other hand, domestic and foreign non-financial firms, Privatisation Investment Funds and managers have been increasing their holdings. The latter, namely the growing managerial ownership, is likely to feature in future ownership dynamics in Slovenia. In fact, in 2002 the desired (optimal ownership stakes estimated by Slovenian managers were 10.8 percentage points higher than their actual stakes. The aim of our paper is to describe the main trends in the ownership of Slovenian corporations in the post-privatisation period and to provide an answer to the basic economic question: what is the influence of the ongoing consolidation of managerial ownership on the performance of Slovenian firms. The empirical analysis testing this relationship is based on a panel of 182 Slovenian firms in the 1995-99 period and does not provide relevant evidence of any positive effects of the increasing managerial control on Slovenian firms’ performance. If any, a positive incentive effect is only observed in those firms whose managers’ holdings exceed 10-percent, only with regards to firms’ financial performance (but not total factor productivity and only in firms that are not listed on the capital market. Further, the negative effect of the current gap between the desired and actual managerial ownership seems to exceed any positive incentive effect arising out of managerial ownership

Full Text Available Kathrin Wunsch, Nadine Kasten, Reinhard Fuchs Department of Sport Science, Sport Psychology Unit, Albert-Ludwigs University Freiburg, Freiburg im Breisgau, Germany Abstract: The stress-buffering hypothesis postulates that physical activity and exercise can buffer the negative effects of (academic stress on health. It still remains an open question whether students, who regularly engage in physical activity and exercise within their academic examination period, can successfully diminish these negative effects. Sixty-four subjects participated in this study and completed a total of five surveys, with T1 at the end of the semester break (baseline and T2–T5 being presented every Friday in the last 4 weeks of the semester (examination period. They were asked to answer questions about their activity level, sleep quality, well-being and affect. Hierarchical linear models showed significant dependencies on time for all dependent measures. The expansion of the model for exercise also showed significant main effects of this predictor on well-being and positive affect (PA and negative affect. Moreover, significant interactions with time for sleep quality and PA were found. Results suggest that physical activity and exercise in the academic examination period may be able to buffer the negative effects of stress on health-related outcomes. Therefore, activity levels should be maintained in times of high stress to prevent negative effects on sleep, well-being and affect in students.

De Muer, D.; De Backer, H.; Zawodny, J. M.; Veiga, R. E.

1990-01-01

The ozone profiles obtained from 24 balloon soundings at Uccle (50 deg 48 min N, 4 deg 21 min E) made with electrochemical ozonesondes were used as correlative data for SAGE II ozone profiles retrieved within a distance of at most 600 km from Uccle. The agreement between the two data sets is in general quite good, especially for profiles nearly coincident in time and space, and during periods of little dynamic activity over the area considered. The percent difference between the ozone column density of the mean balloon and SAGE profile is 4.4 percent (-3.3) percent in the altitude region between 10 and 26 km. From a statistical analysis it appears that there is a small but meaningful difference between the mean profiles at the level of the ozone maximum and around the 30-km level. An error analysis of both data sets give similar results, leading to the conclusion that these differences are instrumentally induced. However, differences between the mean profiles in the lower stratosphere are probably real and due to the high ozone variability in time and space in that altitude region.

What Is the Best Way to Measure Surgical Quality? Comparing the American College of Surgeons National Surgical Quality Improvement Program versus Traditional Morbidity and Mortality Conferences.

Morbidity and mortality conferences have played a traditional role in tracking complications. Recently, the American College of Surgeons National Surgical Quality Improvement Program Pediatrics (ACS NSQIP-P) has gained popularity as a risk-adjusted means of addressing quality assurance. The purpose of this article is to report an analysis of the two methodologies used within pediatric plastic surgery to determine the best way to manage quality. ACS NSQIP-P and morbidity and mortality data were extracted for 2012 and 2013 at a quaternary care institution. Overall complication rates were compared statistically, segregated by type and severity, followed by a subset comparison of ACS NSQIP-P-eligible cases only. Concordance and discordance rates between the two methodologies were determined. One thousand two hundred sixty-one operations were performed in the study period. Only 51.4 percent of cases were ACS NSQIP-P eligible. The overall complication rates of ACS NSQIP-P (6.62 percent) and morbidity and mortality conferences (6.11 percent) were similar (p = 0.662). Comparing for only ACS NSQIP-P-eligible cases also yielded a similar rate (6.62 percent versus 5.71 percent; p = 0.503). Although different complications are tracked, the concordance rate for morbidity and mortality and ACS NSQIP-P was 35.1 percent and 32.5 percent, respectively. The ACS NSQIP-P database is able to accurately track complication rates similarly to morbidity and mortality conferences, although it samples only half of all procedures. Although both systems offer value, limitations exist, such as differences in definitions and purpose. Because of the rigor of the ACS NSQIP-P, we recommend that it be expanded to include currently excluded cases and an extension of the study interval.

From the combined 2010 and 2013 National Health Interview Surveys, we estimated US national age-standardized prevalence of adults with active epilepsy who reported that a nervous system/sensory organ condition caused a limitation (e.g., walking; memory; or physical, mental, or emotional problems) and, separately, that epilepsy interfered with their activities (e.g., working, schooling, or socializing) during the 30days preceding the survey. Sixty-one percent of adults who took antiseizure medication and had recent seizures and 51% of those who took medication and had no seizures reported having limitations caused by a nervous system/sensory organ condition. Sixty-two percent of adults who took antiseizure medication and had recent seizures and 20% of those who took medication and had no seizures reported that epilepsy or its treatment interfered with their recent activities. Forty-one percent of those who did not take medication and had recent seizures also reported that epilepsy interfered with their activities. To reduce activity limitations in people with epilepsy, health and social service providers can ensure that adequate policies and practices that promote access to high quality care and social participation are in effect in organizations and communities.

A simple and accurate spectrophotometric method for the determination of arbutin (glycosylated hydroquinone) is described. It is based on the oxidation of arbutin by periodate in presence of iodate. Excess periodate causes liberation of iodine at pH 8.0. The unreacted periodate is determined by measurement of the liberated iodine spectrophotometrically in the wavelength range (300-500 nm). A calibration curve was constructed for more accurate results and the correlation coefficient of linear regression analysis was -0.9778. The precision of this method was better than 6.17% R.S.D. ( n = 3). Regression analysis of Bear-Lambert plot shows good correlation in the concentration range 25-125 ug/ml. The identification limit was determined to be 25 ug/ml a detailed study of the reaction conditions was carried out, including effect of changing pH, time, temperature and volume of periodate. Analyzing pure and authentic samples containing arbutin tested the validity of the proposed method which has an average percent recovery of 100.86%. An alternative method is also proposed which involves a complexation reaction between arbutin and ferric chloride solution. The produced complex which is yellowish-green in color was determined spectophotometrically.

WHO reported more than 3 million people die from COPD in 2012 and are expected to rank third after cardiovascular and cancer diseases in the future. Recent studies reported the prevalence of depression in COPD patients was higher than in control group. So, it’s important for clinicians to understand the relationship of depression symptoms with clinical aspects of COPD. For determining the association of depression symptoms with lung function and BODE index in patients with stable COPD, a cross-sectional study was in 98 stable COPD outpatients from January to June 2017. Data were analyzed using Independent t-test, Mann-Whitney test, and Spearman’s rank correlation. COPD patients with depression had higher mMRC scores, and lower FEV1 percent predicted, and then 6-Minutes Walk Test compared to those without depression. There was a moderate strength of correlation (r=-0.43) between depression symptoms and FEV1 percent predicted, and strong correlation (r=0.614) between depression symptoms and BODE index. It indicates that BODE index is more accurate to describe symptoms of depression in COPD patients.

Orientation of public and physicians to the complementary and alternative medicine (CAM) is one of the most prominent symbols of structural changes in the health service system. The aim of his study was a determination of knowledge, attitude, and practice of general practitioners in complementary and alternative medicine. This cross- sectional study was conducted in Qazvin, Iran in 2013. A self-administered questionnaire was used for collecting data including four information parts: population information, physicians' attitude and knowledge, methods of getting information and their function. A total of 228 physicians in Qazvin comprised the population of study according to the deputy of treatment's report of Qazvin University of Medical Sciences. A total of 150 physicians were selected randomly, and SPSS Statistical program was used to enter questionnaires' data. Results were analyzed as descriptive statistics and statistical analysis. Sixty percent of all responders were male. About sixty (59.4) percent of participating practitioners had worked less than 10 years.96.4 percent had a positive attitude towards complementary and alternative medicine. Knowledge of practitioners about traditional medicine in 11 percent was good, 36.3% and 52.7% had average and little information, respectively. 17.9% of practitioners offered their patients complementary and alternative medicine for treatment. Although there was little knowledge among practitioners about traditional medicine and complementary approaches, a significant percentage of them had attitude higher than the lower limit.

Aim: To determine current practice and perceptions of the adequacy of training and support received for the reporting of skeletal surveys in suspected physical child abuse. Materials and methods: A list of telephone numbers of UK hospitals with a radiology department was obtained from Royal College of Radiologists. One hundred hospitals were then randomly selected for inclusion in the survey. An 18-item questionnaire was successfully administered to consultant radiologists from 84 departments. Results: Sixty-one percent of departments had a named radiologist to report their skeletal surveys, 16% assigned surveys to a random radiologist, and 23% referred them elsewhere. Only 52% of departments had a dedicated paediatric radiologist, thus in a significant proportion of departments (25%) initial reports on skeletal surveys for physical abuse were provided by non-paediatric radiologists. Fifteen percent did not have ready access to a paediatric radiology opinion. Sixty-one percent thought that the service could be improved. Expert evidence was provided by 5% of respondents. Seventy-three percent would never consider providing expert evidence, even if given adequate radiology and/or legal training. Conclusion: The survey shows significant dissatisfaction amongst consultant radiologists with the current service, confirms a low number of paediatric radiologists taking on this work, and suggests the potential to increase numbers of radiology child abuse experts by 27% if given improved training and support. Appropriate service and education strategies should be implemented.

A series of photocatalysts TiO 2 /CFA were prepared using coal fly ash (CFA), waste discharged from coal-fired power plant, as substrate, and then these photocatalysts were characterized by scanning electron microscope, X-ray diffraction analysis, nitrogen adsorption test and ultraviolet-visible absorption analysis. The effects of loading percent of TiO 2 on the photocatalytic activity and re-use property of TiO 2 /CFA were evaluated by the photocatalytic decoloration and mineralization of methyl orange solution. The results show that the pore volume and the specific surface area of the TiO 2 /CFA both increased with the increase in the loading percent of TiO 2 , which improved the photocatalytic activity of TiO 2 /CFA. However, when the loading percent of TiO 2 was too high (up to 54.51%), superfluous TiO 2 was easy to break away from CFA in the course of water treatment, which was disadvantaged to the recycling property of TiO 2 /CFA. In this study, the optimal loading percent of TiO 2 was 49.97%, and the efficiencies of photocatalytic decoloration and mineralization could be maintained above 99% and 90%, respectively, when the photocatalyst was used repeatedly, without any decline, even at the sixth cycle.

Recent studies have shown that personal best marathon time is a strong predictor of race time in male ultramarathoners. We aimed to determine variables predictive of marathon race time in recreational male marathoners by using the same characteristics of anthropometry and training as used for ultramarathoners. Anthropometric and training characteristics of 126 recreational male marathoners were bivariately and multivariately related to marathon race times. After multivariate regression, running speed of the training units (β = -0.52, P marathon race times. Marathon race time for recreational male runners may be estimated to some extent by using the following equation (r (2) = 0.44): race time ( minutes) = 326.3 + 2.394 × (percent body fat, %) - 12.06 × (speed in training, km/hours). Running speed during training sessions correlated with prerace percent body fat (r = 0.33, P = 0.0002). The model including anthropometric and training variables explained 44% of the variance of marathon race times, whereas running speed during training sessions alone explained 40%. Thus, training speed was more predictive of marathon performance times than anthropometric characteristics. The present results suggest that low body fat and running speed during training close to race pace (about 11 km/hour) are two key factors for a fast marathon race time in recreational male marathoner runners.

Despite tobacco control and health promotion efforts, the incidence rates of mouth cancer are increasing across most regions in India. Analysing the influence of age, time period and birth cohort on these secular trends can point towards underlying factors and help identify high-risk populations for improved cancer control programmes. We evaluated secular changes in mouth cancer incidence among men and women aged 25-74 years in Mumbai between 1995 and 2009 by calculating age-specific and age-standardized incidence rates (ASR). We estimated the age-adjusted linear trend for annual percent change (EAPC) using the drift parameter, and conducted an age-period-cohort (APC) analysis to quantify recent time trends and to evaluate the significance of birth cohort and calendar period effects. Over the 15-year period, age-standardized incidence rates of mouth cancer in men in Mumbai increased by 2.7% annually (95% CI:1.9 to 3.4), pMumbai cancer registry indicate a significant linear increase of mouth cancer incidence from 1995 to 2009 in men, which was driven by younger men aged 25-49 years, and a non-significant upward trend in similarly aged younger women. Health promotion efforts should more effectively target younger cohorts. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

Full Text Available "The diverse papers that were presented at the 1996 Mogollon Conference reveal the geographic, intellectual, and temporal scope of contemporary Mogollon archaeology, and almost nothing of the historical controversy surrounding the Mogollon culture concept" (Whittlesey 1999:vii. With these words, Stephanie M. Whittlesey makes it clear in the preface that Sixty Years of Mogollon Archaeology: Papers From the Ninth Mogollon Conference, Silver City, New Mexico, 1996 (SRl Press 2000 contains few papers on the history of Mogollon archaeology. It might therefore be more appropri­ately titled "Current Research in Mogollon Archaeology."

Percent wall thickness evaluated by Gd-DTPA enhanced cine MRI as an indicator of local parietal movement in hypertrophic cardiomyopathy

International Nuclear Information System (INIS)

Hirano, Masaharu

1998-01-01

Hypertrophic cardiomyopathy (HCM) is a cardiac disease, the basic pathology of which consists of a decrease in left ventricular dilation compliance due to uneven hypertrophy of the left ventricular wall. Magnetic resonance imaging (MRI) is useful in monitoring uneven parietal hypertrophy and kinetics in HCM patients. The present study was undertaken in 47 HCM patients who showed asymmetrical septal hypertrophy to determine if percent thickness can be an indicator of left ventricular local movement using cine MRI. Longest and shortest axis images were acquired by the ECG synchronization method using a 1.5 T MR imager. Cardiac function was analyzed based on longest axis cine images, and telediastolic and telesystolic parietal thickness were measured based on shorter axis cine images at the papillary muscle level. Parietal movement index and percent thickness were used as indicators of local parietal movement. The correlation between these indicators and parietal thickness was evaluated. The percent thickness changed at an earlier stage of hypertrophy than the parietal movement index, thus it is thought to be useful in detecting left ventricular parietal movement disorders at an early stage of HCM.

Possible Periodic Orbit Control Maneuvers for an eLISA Mission

Science.gov (United States)

Bender, Peter L.; Welter, Gary L.

2012-01-01

This paper investigates the possible application of periodic orbit control maneuvers for so-called evolved-LISA (eLISA) missions, i.e., missions for which the constellation arm lengths and mean distance from the Earth are substantially reduced. We find that for missions with arm lengths of 106 km and Earth-trailing distance ranging from approx. 12deg to 20deg over the science lifetime, the occasional use of the spacecraft micro-Newton thrusters for constellation configuration maintenance should be able to essentially eliminate constellation distortion caused by Earth-induced tidal forces at a cost to science time of only a few percent. With interior angle variation kept to approx. +/-0:1deg, the required changes in the angles between the laser beam pointing directions for the two arms from any spacecraft could be kept quite small. This would considerably simplify the apparatus necessary for changing the transmitted beam directions.

To understand perceptions of faculty and students about attendance policies in baccalaureate nursing programs. Classroom attendance is an issue of debate across academic disciplines. A mixed-methods study was conducted using qualitative data from a stratified random sample of 65 accredited baccalaureate nursing programs; 591 students and 91 faculty from 19 schools responded. Sixty-two percent of faculty thought students who missed class exhibited unprofessional behavior; 69 percent believed students who missed class were less successful in the clinical setting. Students (57 percent) and faculty (66 percent) believed there should be an attendance policy. Twenty-nine students reported needing a break in workload (16.8 percent) or did not find class time valuable (11.8 percent). Variability exists in student and faculty beliefs regarding attendance policies. Understanding these viewpoints and utilizing creative teaching approaches will facilitate learning and create an environment of teamwork and mutual respect.

Procedures are described for extruding the U--0.75 wt percent Ti alloy in the high alpha region (600 to 640 0 C) , and in the upper gamma region (900 to 1000 0 C). The casting of sound extrusion billets has importance in the production of sound extrusions, and procedures are given for casting sound billets up to 1,100 kilograms . Also important in producing sound extrusions is the use of glass lubricants. Reduction ratios of greater than 50 to 1 were achieved on reasonably sized billets. Extrusion constants of 48,000 pounds per square inch (psi) [296 megapascals (MPa)] for alpha phase (630 0 C) and 8,000 psi (56 MPa) for gamma phase (950 0 C) were achieved. Gamma-phase extrusion has preference over alpha-phase extrusion in that larger billets can be used and temperature control is not as critical. However alpha-phase extrusion offers better surface finish, less die wear, and fewer oxidation problems. Billets up to 14 inches in diameter have been successfully gamma-extruded and plans exist for extruding billets up to 20 inches (508 millimetres) in diameter. (U.S.)

Joy, JM, Lowery, RP, Oliveira de Souza, E, and Wilson, JM. Elastic bands as a component of periodized resistance training. J Strength Cond Res 30(8): 2100-2106, 2016-Variable resistance training (VRT) has recently become a component of strength and conditioning programs. Prior research has demonstrated increases in power and/or strength using low loads of variable resistance. However, no study has examined using high loads of variable resistance as a part of a periodized training protocol to examine VRT within the context of a periodized training program and to examine a greater load of variable resistance than has been examined in prior research. Fourteen National Collegiate Athletic Association division II male basketball players were recruited for this study. Athletes were divided equally into either a variable resistance or control group. The variable resistance group added 30% of their 1 repetition maximum (1RM) as band tension to their prescribed weight 1 session per week. Rate of power development (RPD), peak power, strength, body composition, and vertical jump height were measured pretreatment and posttreatment. No baseline differences were observed between groups for any measurement of strength, power, or body composition. A significant group by time interaction was observed for RPD, in which RPD was greater in VRT posttraining than in the control group. Significant time effects were observed for all other variables including squat 1RM, bench press 1RM, deadlift 1RM, clean 3RM, vertical jump, and lean mass. Although there were no significant group ×-time interactions, the VRT group's percent changes and effect sizes indicate a larger treatment effect in the squat and bench press 1RM values and the vertical jump performed on the force plate and vertec. These results suggest that when using variable resistance as a component of a periodized training program, power and strength can be enhanced. Therefore, athletes who add variable resistance to 1 training

Charged with transforming geriatric emergency care by applying palliative care principles, a process improvement team at New York City's Mount Sinai Medical Center developed the GEDI WISE (Geriatric Emergency Department Innovations in Care through Workforce, Informatics, and Structural Enhancements) model. The model introduced workforce enhancements for emergency department (ED) and adjunct staff, including role redefinition, retraining, and education in palliative care principles. Existing ED triage nurses screened patients ages sixty-five and older to identify those at high risk of ED revisit and hospital readmission. Once fully trained, these nurses screened all but 6 percent of ED visitors meeting the screening criteria. Newly hired ED nurse practitioners identified high-risk patients suitable for and desiring palliative and hospice care, then expedited referrals. Between January 2011 and May 2013 the percentage of geriatric ED admissions to the intensive care unit fell significantly, from 2.3 percent to 0.9 percent, generating an estimated savings of more than $3 million to Medicare. The decline in these admissions cannot be confidently attributed to the GEDI WISE program because other geriatric care innovations were implemented during the study period. GEDI WISE programs are now running at Mount Sinai and two partner sites, and their potential to affect the quality and value of geriatric emergency care continues to be examined.

To estimate the prevalence and to describe the clinical characteristics of gestational diabetes mellitus (GDM) in pregnant women receiving health care services at the Puerto Rico University Hospital from 1997 to 1998. The study design was cross-sectional. All medical records available of pregnant women diagnosed with GDM were retrospectively reviewed. Descriptive statistics such as frequency distributions and summary measures (mean and standard deviation) were used. Annual and 18-month period prevalences of GDM were calculated. Fisher's exact test was used to compare proportions. A total of 78 medical records were available during the 18-month study period (June 1997 to December 1998). The estimated prevalence of GDM was 2% for the total study period (18-month) as well as for the year 1998. The highest proportion (52.3%) of GDM cases was found in the 30 years or less age group. Forty-eight percent had a body mass index (BMI) > or = 30 m/kg2 (obese) before pregnancy; however, the weight gained during the last pregnancy was higher than 15 pounds (57%). Sixty-four percent of the cases had a family history of diabetes, meanwhile, 34.7% reported a history of GDM during previous pregnancies. During the first prenatal visit, 80.5% reflected glucose levels higher than 110 mg/ml. Preeclampsia (6.4%) and macrosomia (14%) were the most frequent complications for the mother and the fetus, respectively. More epidemiological studies about GMD in Puerto Rico need to be performed to better describe the prevalence of the condition in the island.

Causes of prolonged jaundice in infancy: 3-year experience in a tertiary paediatric centre.

2016-01-29

Although prolonged jaundice (PJ) commonly occurs in infancy, there is not yet agreement as to the appropriate extent of investigations, particularly in otherwise well children. Significant pathologies may present with PJ in this age group and need to be considered. The aim of this retrospective study was to ascertain the causes of PJ in infants referred to a single tertiary paediatric centre. Infants referred with PJ over a 3-year period were identified. Clinical documentation, electronic notes and results of investigations performed prior to and after referral were reviewed. One hundred and sixty-seven infants with PJ were seen. Fifty-eight percent were over 28 days of age. Four patients had conjugated hyperbilirubinaemia. Eighteen percent of patients were found to have a specific medical diagnosis causing or contributing to PJ, almost half of whom had normal clinical examination. The single most common pathological cause for PJ was hypothyroidism found in six patients. This study demonstrates that normal clinical examination and exclusion of conjugated hyperbilirubinaemia are insufficient to exclude pathological causes of PJ. Overall, these children were referred late. Guidelines, in conjunction with education initiatives, are required to optimise the management of prolonged jaundice in infancy.

We report a reanalysis of a near-pristine absorption system, located at a redshift {z}abs}=2.52564 toward the quasar Q1243+307, based on the combination of archival and new data obtained with the HIRES echelle spectrograph on the Keck telescope. This absorption system, which has an oxygen abundance [O/H] = ‑2.769 ± 0.028 (≃1/600 of the solar abundance), is among the lowest metallicity systems currently known where a precise measurement of the deuterium abundance is afforded. Our detailed analysis of this system concludes, on the basis of eight D I absorption lines, that the deuterium abundance of this gas cloud is {log}}10({{D}}/{{H}})=-4.622+/- 0.015, which is in very good agreement with the results previously reported by Kirkman et al., but with an improvement on the precision of this single measurement by a factor of ∼3.5. Combining this new estimate with our previous sample of six high precision and homogeneously analyzed D/H measurements, we deduce that the primordial deuterium abundance is {log}}10{({{D}}/{{H}})}{{P}}=-4.5974+/- 0.0052 or, expressed as a linear quantity, {10}5{({{D}}/{{H}})}{{P}}=2.527+/- 0.030; this value corresponds to a one percent determination of the primordial deuterium abundance. Combining our result with a big bang nucleosynthesis (BBN) calculation that uses the latest nuclear physics input, we find that the baryon density derived from BBN agrees to within 2σ of the latest results from the Planck cosmic microwave background data. Based on observations collected at the W.M.

We assessed clinical and early electrophysiological characteristics, in particular Generalized Periodic Epileptiform Discharges (GPEDs) patterns, of consecutive patients during a 1-year period, hospitalized in the Intensive Care Unit (ICU) after resuscitation following cardiac arrest (CA). Consecutive patients resuscitated from cardiac arrest (CA) with first EEG recordings within 48hours were included. Clinical data were collected from hospital records, in particular therapeutic hypothermia. Electroencephalograms (EEGs) were re-analyzed retrospectively. Sixty-two patients were included. Forty-two patients (68%) were treated with therapeutic hypothermia according to international guidelines. Global mortality was 74% but not significantly different between patients who benefited from therapeutic hypothermia compared to those who did not. All the patients who did not have an initial background activity (36/62; 58%) died. By contrast, initial background activity was present in 26/62 (42%) and among these patients, 16/26 (61%) survived. Electroencephalography demonstrated GPEDs patterns in 5 patients, all treated by therapeutic hypothermia and antiepileptic drugs. One of these survived and showed persistent background activity with responsiveness to benzodiazepine intravenous injection. Patients presenting suppressed background activity, even when treated by hypothermia, have a high probability of poor outcome. Thorough analysis of EEG patterns might help to identify patients with a better chance of survival. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Within the frame work of lumbal myelography, 158 patients were entired in a double-blind study in order to test a dimeric contrast medium (iotrolan) against a monomeric one (iopamidol), both of them non-ionic. A three-step scheme was applied to evaluate the X-ray pictures with respect ot contrast quality. Particular attention was paid to the visibility of details, i.e. the nerve root and its course, as well as to its how well it could be distinguished in the nerve root sheath. On the basis of a high level of significance (P<0.05), comparison of the two contrast media showed no difference in contrast quality. Sixty-nine percent of the examinations using iotrolan resulted in excellent contrast quality, whereas the corresponding very good results using iopamidol lay at 76%. Twenty-nine percent of the patients examined with iotrolan and 27% of those examined with iopamidol showed side effects. Headache occurred most frequently, followed by nausea, dizziness and neck pain. Sixty percent of the patients suffering from postmyelographic reactions reported delayed headache, which occurred most often with iotrolan rather than iopamidol. As for manifestation of other postmyelographic side effects, there were no significant differences (P<0.05, Fischer's test) between the two groups of contrast media. (orig.).

FINANCIAL PROBLEMS OF BOTTOM 40 PERCENT BUMIPUTERA IN MALAYSIA: A POSSIBLE SOLUTION THROUGH WAQF-BASED CROWDFUNDING

Directory of Open Access Journals (Sweden)

Abidullah ABID

2017-02-01

Full Text Available Low savings by the bottom 40 percent Bumiputera triggered low wealth accumulation and greater wealth inequality. The issue behind the low savings is the increase in food prices, taxes, and interest rates for the borrowers. In response to these problems, the Malaysian government provides cash transfer BRIM as one of redistributive measures. However, it is still not enough as many of the bottom 40 percent are neglected to avail the facility. In such circumstances, the role of community-based cash and credit transfer schemes such as cash waqf can be more fruitful. However due to inefficiency of the awqaf institutions regarding financial management, the system cannot contribute effectively. Therefore, the main aim of the paper is to provide an efficient mechanism which can ensure effectiveness in terms of transparency, collection and distribution of cash endowments and its benefits. Hence, by means of library research, we have proposed a conceptual framework. It is suggested that collection and distribution of cash waqf through crowdfunding platform would solve both transparency, collection and distribution issues. This study would provide a ground for those researchers and practitioners who are working on finding the right approach to implement waqf in more efficient way.

Microscope work can be strenuous both to the visual system and the musculoskeletal system. Lack of awareness or indifference towards health issues may result in microscope users becoming victim to many occupational hazards. Our objective was to understand the occupational problems associated with regular use of microscope, awareness regarding the hazards, attitude and practice of microscope users towards the problems and preventive strategies. a questionnaire based survey done on 50 professionals and technicians who used microscope regularly in pathology, microbiology, hematology and cytology laboratories. Sixty two percent of subjects declared that they were suffering from musculoskeletal problems, most common locations being neck and back. Maximum prevalence of musculoskeletal problems was noted in those using microscope for 11-15 years and for more than 30 h/week. Sixty two percent of subjects were aware of workplace ergonomics. Fifty six percent of microscope users took regular short breaks for stretching exercises and 58% took visual breaks every 15-30 min in between microscope use sessions. As many as 94% subjects reported some form of visual problem. Fourty four percent of microscope users felt stressed with long working hours on microscope. The most common occupational concerns of microscope users were musculoskeletal problems of neck and back regions, eye fatigue, aggravation of ametropia, headache, stress due to long working hours and anxiety during or after microscope use. There is an immediate need for increasing awareness about the various occupational hazards and their irreversible effects to prevent them.

Female football is becoming an increasingly popular women's team sports discipline around the world. The Women's Football Committee in Polish Football Association (WFC_PFA) has developed a long-term strategic plan to popularize the discipline across the country and enhance girls' participation. On one hand, it is postulated to increase the number of female footballers, and on the other hand it is crucial to decrease the number of girls quitting football prematurely. To find the reasons for sports career termination among female football players. cross-sectional with retrospective information about reasons of career termination. On-line questionnaire was filled out by on-line access. Ninety-three former female footballers. factors leading to career termination. Participants completed the on-line questionnaire. The analysis was performed referring to two groups: "injury group" - in which the injury was the main reason for quitting football, and "other group" - in which the female player stopped playing football due to all other factors. Thirty percent of former Polish female football players terminated their career due to a long-term treatment for an injury. Over 27 percent (27.7%) females had ended their careers because they were not able to reconcile sports with work/studying. Over 10 percent (10.8%) of former football players reported that becoming a wife and/or mother was the reason for career termination. Losing motivation and interest in sport was reported by 9.2%(n=6) of present study participants who decided to terminate the career due to non-injury reasons. The results clearly show that more effort is needed to support female football players, especially after an injury, so that they do not quit the sport voluntarily.

Safe nuclear power

Nearly 22 percent of the electricity generated in the United States already comes from nuclear power plants, but no new plants have been ordered since 1978. This paper reports that the problems that stand in the way of further development have to do with complexity and perceived risk. Licensing, construction management, and waste disposal are complex matters, and the possibility of accident has alienated a significant portion of the public. But a national poll conducted by Bruskin/Goldring at the beginning of February shows that opposition to nuclear energy is softening. Sixty percent of the American people support (strongly or moderately) the use of nuclear power, and 18 percent moderately oppose it. Only 15 percent remain obstinately opposed. Perhaps they are not aware of recent advances in reactor technology

Full Text Available Summary Objective: a resistance of hospital-acquired bacteria to multiple antibiotics is a major concern worldwide. The objective of this study was to investigate multidrugresistant (MDR bacteria, clinical specimens, origin of specimen and trends, and correlate these with bacterial sensitivity and consumption of antimicrobials. Methods: 9,416 bacteria of nosocomial origin were evaluated in a tertiary hospital, from 1999 to 2008. MDR was defined for Gram-negative bacteria (GNB as resistance to two or more classes/groups of antibiotics. Results: GNB MDR increased by 3.7 times over the study period (p<0.001. Acinetobacter baumannii was the most prevalent (36.2%. Over the study period, there were significant 4.8-fold and 14.6-fold increases for A. baumannii and K. pneumoniae (p<0.001, respectively. Sixty-seven percent of isolates of MDR GNB were isolated in intensive care units. The resistance of A. baumannii to carbapenems increased from 7.4 to 57.5% during the study period and concomitant with an increased consumption. Conclusion: that decade showed prevalence of GNB and a gradual increase in MDR GNB. There was an increase in carbapenem resistance of 50.1% during the study.

Immigrants in the one percent: The national origin of top wealth owners.

Science.gov (United States)

Keister, Lisa A; Aronson, Brian

2017-01-01

Economic inequality in the United States is extreme, but little is known about the national origin of affluent households. Households in the top one percent by total wealth own vastly disproportionate quantities of household assets and have correspondingly high levels of economic, social, and political influence. The overrepresentation of white natives (i.e., those born in the U.S.) among high-wealth households is well-documented, but changing migration dynamics suggest that a growing portion of top households may be immigrants. Because no single survey dataset contains top wealth holders and data about country of origin, this paper uses two publicly-available data sets: the Survey of Consumer Finances (SCF) and the Survey of Income and Program Participation (SIPP). Multiple imputation is used to impute country of birth from the SIPP into the SCF. Descriptive statistics are used to demonstrate reliability of the method, to estimate the prevalence of immigrants among top wealth holders, and to document patterns of asset ownership among affluent immigrants. Significant numbers of top wealth holders who are usually classified as white natives may be immigrants. Many top wealth holders appear to be European and Canadian immigrants, and increasing numbers of top wealth holders are likely from Asia and Latin America as well. Results suggest that of those in the top one percent of wealth holders, approximately 3% are European and Canadian immigrants, .5% are from Mexico or Cuban, and 1.7% are from Asia (especially Hong Kong, Taiwan, Mainland China, and India). Ownership of key assets varies considerably across affluent immigrant groups. Although the percentage of top wealth holders who are immigrants is relatively small, these percentages represent large numbers of households with considerable resources and corresponding social and political influence. Evidence that the propensity to allocate wealth to real and financial assets varies across immigrant groups suggests that

Estimation of the volume and percent uptake of the liver and spleen by SPECT

Yamagata, Atushi

1988-01-01

The volume and percent uptake of the liver and spleen were estimated with single photon emission computed tomography (SPECT) using 99m Tc-phytate. Clinical usefulness of these parameters was evaluated by comparison with other liver function tests in 87 patients including 25 normal controls, 24 liver cirrhosis and 16 other chronic liver diseases. SPECT images were obtained by Maxi Camera 400T. Cut-off level for reconstruction of images and relationship between counts and activity (mCi) were obtained from phantom studies. Volumes estimated using SPECT and computed tomography were compared in 16 patients. Results obtained were as follows. 1) Optimal cut-off level for measurement of volumes for the liver was 37 % and for the spleen was 42 %. 2) Correlation between organ volumes estimated with CT and SPECT was good (r = 0.92 for the liver and r = 0.96 for the spleen), although volumes measured with SPECT were larger than those with CT. 3) Significant differences of percent uptake were observed between normal controls and liver cirrhosis. 4) Better correlation between spleen volumes and uptake was recognized in cases without liver cirrhosis than in cases with liver cirrhosis. The spleen uptake in liver cirrhosis was higher than those in others in comparison with the volume. 5) The liver/spleen ratio of 99m Tc-phytae uptake could most clearly differentiate liver cirrhosis from others. 6) Negative correlation was observed between liver volume or uptake and ICG (R 15 ). Estimation of volume and uptake of the liver and spleen could be a useful procedure to assess liver function, probably related with effective hepatic blood flow in liver cirrhosis. (author)

Questionnaires were sent to 270 patients who had undergone abdominoperineal resection and sigmoid colostomy at the Mayo Clinic, Rochester, Minn, during the ten years from 1972 to 1982; 223 patients returned their questionnaires with evaluable data. Sixty percent of the patients were continent with irrigation, and 22% were incontinent with irrigation. Eighteen percent had discontinued irrigation for various reasons. The proportion continent was higher in women, younger patients, and previously constipated patients. A poorly constructed colostomy may cause acute angle, parastoma hernia, stomal prolapse, or stenosis and thus be the cause of failure of irrigation.

The aim of this study was to determine the efficacy and safety of dialectical behavior therapy plus olanzapine compared with dialectical behavior therapy plus placebo in patients with borderline personality disorder. Sixty patients with borderline personality disorder were included in a 12-week, double-blind, placebo-controlled study. All patients received dialectical behavior therapy and were randomly assigned to receive either olanzapine or placebo following a 1-month baseline period. Seventy percent of the patients completed the 4-month trial. Combined treatment showed an overall improvement in most symptoms studied in both groups. Olanzapine was associated with a statistically significant improvement over placebo in depression, anxiety, and impulsivity/aggressive behavior. The mean dose of olanzapine was 8.83 mg/day. A combined psychotherapeutic plus pharmacological approach appears to lower dropout rates and constitutes an effective treatment for borderline personality disorder.

Full Text Available In order to determine the best indirect selection criteria for genetic improvement of biological nitrogen fixation, sixty four common bean genotypes were cultivated in two randomized complete block design. Genotypes were inoculated with bacteria Rhizobium legominosarum biovar Phaseoli isolate L-109 only in one of the experiments. The second experiment was considered as check for the first. Correlation analysis showed positive and highly significant correlation of majority of the traits with percent of nitrogen fixation. Step-wise regression designated that traits percent of total nitrogen of shoot, number of nodule per plant and biological yield accounted for 92.3 percent of variation exist in percent of nitrogen fixation. Path analysis indicated that these traits have direct and positive effect on percent of nitrogen fixation. Hence, these traits are promising indirect selection criteria for genetic improvement of nitrogen fixation capability in common bean genotypes especially in early generations.

Circadian rhythm phase shifts and endogenous free-running circadian period differ between African-Americans and European-Americans.

2015-02-11

Successful adaptation to modern civilization requires the internal circadian clock to make large phase shifts in response to circumstances (e.g., jet travel and shift work) that were not encountered during most of our evolution. We found that the magnitude and direction of the circadian clock's phase shift after the light/dark and sleep/wake/meal schedule was phase-advanced (made earlier) by 9 hours differed in European-Americans compared to African-Americans. European-Americans had larger phase shifts, but were more likely to phase-delay after the 9-hour advance (to phase shift in the wrong direction). The magnitude and direction of the phase shift was related to the free-running circadian period, and European-Americans had a longer circadian period than African-Americans. Circadian period was related to the percent Sub-Saharan African and European ancestry from DNA samples. We speculate that a short circadian period was advantageous during our evolution in Africa and lengthened with northern migrations out of Africa. The differences in circadian rhythms remaining today are relevant for understanding and treating the modern circadian-rhythm-based disorders which are due to a misalignment between the internal circadian rhythms and the times for sleep, work, school and meals.

Chaos to periodicity and periodicity to chaos by periodic perturbations in the Belousov-Zhabotinsky reaction

2004-01-01

A three-variable model of the Belousov-Zhabotinsky reaction system subject to external sinusoidal perturbations is investigated by means of frequency spectrum analysis. In the period-1 window of the model, the transitions from periodicity to chaos are observed; in the chaotic window, the transitions from chaos to periodicity are found. The former might be understood by the circle map of two coupled oscillators, and the latter is partly explained by the resonance between the main frequency of the chaos and the frequency of the external periodic perturbations

Evaluating the relationship between biomass, percent groundcover and remote sensing indices across six winter cover crop fields in Maryland, United States

Science.gov (United States)

Prabhakara, Kusuma; Hively, W. Dean; McCarty, Gregory W.

2015-07-01

Winter cover crops are an essential part of managing nutrient and sediment losses from agricultural lands. Cover crops lessen sedimentation by reducing erosion, and the accumulation of nitrogen in aboveground biomass results in reduced nutrient runoff. Winter cover crops are planted in the fall and are usually terminated in early spring, making them susceptible to senescence, frost burn, and leaf yellowing due to wintertime conditions. This study sought to determine to what extent remote sensing indices are capable of accurately estimating the percent groundcover and biomass of winter cover crops, and to analyze under what critical ranges these relationships are strong and under which conditions they break down. Cover crop growth on six fields planted to barley, rye, ryegrass, triticale or wheat was measured over the 2012-2013 winter growing season. Data collection included spectral reflectance measurements, aboveground biomass, and percent groundcover. Ten vegetation indices were evaluated using surface reflectance data from a 16-band CROPSCAN sensor. Restricting analysis to sampling dates before the onset of prolonged freezing temperatures and leaf yellowing resulted in increased estimation accuracy. There was a strong relationship between the normalized difference vegetation index (NDVI) and percent groundcover (r2 = 0.93) suggesting that date restrictions effectively eliminate yellowing vegetation from analysis. The triangular vegetation index (TVI) was most accurate in estimating high ranges of biomass (r2 = 0.86), while NDVI did not experience a clustering of values in the low and medium biomass ranges but saturated in the higher range (>1500 kg/ha). The results of this study show that accounting for index saturation, senescence, and frost burn on leaves can greatly increase the accuracy of estimates of percent groundcover and biomass for winter cover crops.

Few studies have assessed the role of cross-sex hormones on psychological outcomes during the period of hormonal therapy preceding sex reassignment surgery in transsexuals. The objective of this study was to assess the relationship between hormonal therapy, self-esteem, depression, quality of life (QoL), and global functioning. This study incorporated a cross-sectional design. The inclusion criteria were diagnosis of gender identity disorder (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision) and inclusion in a standardized sex reassignment procedure. The outcome measures were self-esteem (Social Self-Esteem Inventory), mood (Beck Depression Inventory), QoL (Subjective Quality of Life Analysis), and global functioning (Global Assessment of Functioning). Sixty-seven consecutive individuals agreed to participate. Seventy-three percent received hormonal therapy. Hormonal therapy was an independent factor in greater self-esteem, less severe depression symptoms, and greater "psychological-like" dimensions of QoL. These findings should provide pertinent information for health care providers who consider this period as a crucial part of the global sex reassignment procedure.

Effects of dynamic long-period ocean tides on changes in earth's rotation rate

Science.gov (United States)

Nam, Young; Dickman, S. R.

1990-01-01

As a generalization of the zonal response coefficient first introduced by Agnew and Farrell (1978), the zonal response function kappa of the solid earth-ocean system is defined as the ratio, in the frequency domain, of the tidal change in earth's rotation rate to the tide-generating potential. Amplitudes and phases of kappa for the monthly, fortnightly, and nine-day lunar tides are estimated from 2 1/2 years of VLBI UT1 observations, corrected for atmospheric angular momentum effects using NMC wind and pressure series. Using the dynamic ocean tide model of Dickman (1988, 1989), amplitudes and phases of kappa for an elastic earth-ocean system are predicted. The predictions confirm earlier results which found that dynamic effects of the longer-period ocean tides reduce the amplitude of kappa by about 1 percent.

Rest period duration of the coronary arteries: Implications for magnetic resonance coronary angiography

International Nuclear Information System (INIS)

Shechter, Guy; Resar, Jon R.; McVeigh, Elliot R.

2005-01-01

Magnetic resonance (MR) and computed tomography coronary imaging is susceptible to artifacts caused by motion of the heart. The presence of rest periods during the cardiac and respiratory cycles suggests that images free of motion artifacts could be acquired. In this paper, we studied the rest period (RP) duration of the coronary arteries during a cardiac contraction and a tidal respiratory cycle. We also studied whether three MR motion correction methods could be used to increase the respiratory RP duration. Free breathing x-ray coronary angiograms were acquired in ten patients. The three-dimensional (3D) structure of the coronary arteries was reconstructed from a biplane acquisition using stereo reconstruction methods. The 3D motion of the arterial model was then recovered using an automatic motion tracking algorithm. The motion field was then decomposed into separate cardiac and respiratory components using a cardiac respiratory parametric model. For the proximal-to-middle segments of the right coronary artery (RCA), a cardiac RP (<1 mm 3D displacement) of 76±34 ms was measured at end systole (ES), and 65±42 ms in mid-diastole (MD). The cardiac RP was 80±25 ms at ES and 112±42 ms at MD for the proximal 5 cm of the left coronary tree. At end expiration, the respiratory RP (in percent of the respiratory period) was 26±8% for the RCA and 27±17% for the left coronary tree. Left coronary respiratory RP (<0.5 mm 3D displacement) increased with translation (32% of the respiratory period), rigid body (51%), and affine (79%) motion correction. The RCA respiratory RP using translational (27%) and rigid body (33%) motion correction were not statistically different from each other. Measurements of the cardiac and respiratory rest periods will improve our understanding of the temporal and spatial resolution constraints for coronary imaging

Rationale: Although emphysema on computed tomography (CT) is associated with increased morbidity and mortality in patients with and without spirometrically defined chronic obstructive pulmonary disease, no available medications target emphysema outside of alpha-1 antitrypsin deficiency. Transforming growth factor-β and endothelial dysfunction are implicated in emphysema pathogenesis, and angiotensin II receptor blockers (ARBs) inhibit transforming growth factor-β, improve endothelial function, and restore airspace architecture in murine models. Evidence in humans is, however, lacking. Objectives: To determine whether angiotensin-converting enzyme (ACE) inhibitor and ARB dose is associated with slowed progression of percent emphysema by CT. Methods: The Multi-Ethnic Study of Atherosclerosis researchers recruited participants ages 45–84 years from the general population from 2000 to 2002. Medication use was assessed by medication inventory. Percent emphysema was defined as the percentage of lung regions less than −950 Hounsfield units on CTs. Mixed-effects regression models were used to adjust for confounders. Results: Among 4,472 participants, 12% used an ACE inhibitor and 6% used an ARB at baseline. The median percent emphysema was 3.0% at baseline, and the rate of progression was 0.64 percentage points over a median of 9.3 years. Higher doses of ACE or ARB were independently associated with a slower change in percent emphysema (P = 0.03). Over 10 years, in contrast to a predicted mean increase in percent emphysema of 0.66 percentage points in those who did not take ARBs or ACE inhibitors, the predicted mean increase in participants who used maximum doses of ARBs or ACE inhibitors was 0.06 percentage points (P = 0.01). The findings were of greatest magnitude among former smokers (P emphysema. There was no evidence that ACE inhibitor or ARB dose was associated with decline in lung function. Conclusions: In a large population-based study, ACE

Increasing development and increasing water withdrawals for public, industrial, and agricultural water supply threaten to reduce streamflows in the Shenandoah River basin in Virginia. Water managers need more information to balance human water-supply needs with the daily streamflows necessary for maintaining the aquatic ecosystems. To meet the need for comprehensive information on hydrology, water supply, and instream-flow requirements of the Shenandoah River basin, the U.S. Geological Survey and the Northern Shenandoah Valley Regional Commission conducted a cooperative investigation of habitat availability during low-flow periods on the North Fork Shenandoah River. Historic streamflow data and empirical data on physical habitat, river hydraulics, fish community structure, and recreation were used to develop a physical habitat simulation model. Hydraulic measurements were made during low, medium, and high flows in six reaches at a total of 36 transects that included riffles, runs, and pools, and that had a variety of substrates and cover types. Habitat suitability criteria for fish were developed from detailed fish-community sampling and microhabitat observations. Fish were grouped into four guilds of species and life stages with similar habitat requirements. Simulated habitat was considered in the context of seasonal flow regimes to show the availability of flows that sustain suitable habitat during months when precipitation and streamflow are scarce. The North Fork Shenandoah River basin was divided into three management sections for analysis purposes: the upper section, middle section, and lower section. The months of July, August, and September were chosen to represent a low-flow period in the basin with low mean monthly flows, low precipitation, high temperatures, and high water withdrawals. Exceedance flows calculated from the combined data from these three months describe low-flow periods on the North Fork Shenandoah River. Long-term records from three

2006-03-01

The purpose was to compare long-term involvement (LTI) vs short-term involvement (STI) of patients in a Lipid Education Service (LES) and to assess the effects of life-style changes. Patients were referred for LTI and STI by their physicians. Three-hundred eighty-one consecutive patients, 287 LTI and 94 STI, were analyzed. The lipids in LTI patients were all significantly improved. Sixty-six percent of all LDL values were at goal as were 77% of HDL and 62% of triglyceride (NCEP-II criteria). Sixty-two percent of LDL values in coronary artery disease patients were at goal contrasted to a reported range of 9.6%-71%. Life-style changes made significant differences in the percentage of patients at lipid goals. In postprogram follow-up there were significant differences between LTI and STI patients. The LTI patients did much better in improving lipid levels at postprogram follow-up than did STI patients. These results demonstrate the importance of making life-style changes as well as the importance of intensive efforts in achieving meaningful and lasting change.

Video laparoscopic bariatric surgery is the preferred surgical technique for treating morbid obesity. However, pneumoperitoneum can pose risks to the kidneys by causing a decrease in renal blood flow. Furthermore, as in other surgical procedures, laparoscopic bariatric surgery triggers an acute inflammatory response. Neutrophil gelatinase-associated lipocalin is an early and accurate biomarker of renal injury, as well as of the inflammatory response. Anesthetic drugs could offer some protection for the kidneys and could attenuate the acute inflammatory response from surgical trauma. The objective of this study was to compare the effects of two types of anesthetics, propofol and sevoflurane, on the serum levels of neutrophil gelatinase-associated lipocalin during the perioperative period in laparoscopic bariatric surgery. Sixty-four patients scheduled for laparoscopic bariatric surgery were randomized into two anesthesia groups and were administered either total intravenous anesthesia (propofol) or inhalation anesthesia (sevoflurane). In the perioperative period, blood samples were collected at three time points (before anesthesia, 6 hours after pneumoperitoneum and 24 hours after pneumoperitoneum) and urine output was measured for 24 hours. Acute kidney injuries were evaluated by examining both the clinical and laboratory parameters during the postoperative period. The differences between the groups were compared using non-parametric tests. ReBEC (http://www.ensaiosclinicos.gov.br/rg/recruiting/): RBR-8wt2fy None of the patients developed an acute kidney injury during the study and no significant differences were found between the serum neutrophil gelatinase-associated lipocalin levels of the groups during the perioperative period. The choice of anesthetic drug, either propofol or sevoflurane, did not affect the serum levels of neutrophil gelatinase-associated lipocalin during the perioperative period in laparoscopic bariatric surgery.

Between 1950 and 1983, radiation-induced proctitis was diagnosed proctoscopically in 720 patients at the Mayo Clinic. Sixty-two patients with severe colorectal symptoms were treated surgically. The interval from cessation of radiotherapy to onset of symptoms ranged from 3 weeks to 24 months (mean 33 months). The 62 patients underwent a total of 143 operations with 8 operative deaths (13 percent), and 40 patients (65 percent) had 61 complications. The morbidity rate was lower after colostomy alone (44 percent in 27 patients) than after more aggressive operations (80 percent in 35 patients). Transverse loop colostomy and descending colostomy were safer than sigmoid colostomy. The dissection adhesions, opening of tissue planes, and careless manipulation of intestine may result in necrosis and perforation of the intestine, bladder, or vaginal wall; these were the main causes of fecal and other internal fistulas in our study

2016-01-01

Detailed acoustic measurements of the noise from the leading-edge Krueger flap of a 5.75 percent Hybrid Wing Body (HWB) aircraft model were recently acquired with a traversing phased microphone array in the AEDC NFAC (Arnold Engineering Development Complex, National Full Scale Aerodynamics Complex) 40- by 80-Foot Wind Tunnel at NASA Ames Research Center. The spatial resolution of the array was sufficient to distinguish between individual support brackets over the full-scale frequency range of 100 to 2875 Hertz. For conditions representative of landing and take-off configuration, the noise from the brackets dominated other sources near the leading edge. Inclusion of flight-like brackets for select conditions highlights the importance of including the correct number of leading-edge high-lift device brackets with sufficient scale and fidelity. These measurements will support the development of new predictive models.

To explore opinions of undergraduate medical students regarding learning outcomes of the instructional strategy of Problem Based Learning (PBL). In addition their views were sought about the role of tutors and qualities of effective tutors. This was a cross-sectional, questionnaire based study which was conducted in two colleges of Medicine, Central region, Saudi Arabia during the period of 1st of April to 30(th) June 2012. One hundred seventy four undergraduate medical students participated in this study. Seventy percent of participants have indicated that PBL strategy contributed to the development of their knowledge, presentation skills, team work abilities, and accepting criticism from other colleagues. Regarding the tutors' role in PBL tutorials, majority of the participants (75%) indicated that this role is essential, nevertheless, only 58% of students indicated that this role is clear and well identified. Sixty three percent of participants preferred a member role in the PBL tutorials and 80 percent of participants preferred both content and process expert tutors in the PBL tutorials. Significant statistical difference was noted between the views of students and their schools, gender, and study phase. Majority of the participants believed that PBL had a positive impact on the development of their cognitive, personal and teamwork skills. The view of the students in this study and the available evidence suggest that tutor should have both qualities; content and process expertise, in order to have the best outcomes from the PBL tutorials.

Garima Jain

2014-08-01

Full Text Available Objectives: Microscope work can be strenuous both to the visual system and the musculoskeletal system. Lack of awareness or indifference towards health issues may result in microscope users becoming victim to many occupational hazards. Our objective was to understand the occupational problems associated with regular use of microscope, awareness regarding the hazards, attitude and practice of microscope users towards the problems and preventive strategies. Material and Methods: A questionnaire based survey done on 50 professionals and technicians who used microscope regularly in pathology, microbiology, hematology and cytology laboratories. Results: Sixty two percent of subjects declared that they were suffering from musculoskeletal problems, most common locations being neck and back. Maximum prevalence of musculoskeletal problems was noted in those using microscope for 11–15 years and for more than 30 h/week. Sixty two percent of subjects were aware of workplace ergonomics. Fifty six percent of microscope users took regular short breaks for stretching exercises and 58% took visual breaks every 15–30 min in between microscope use sessions. As many as 94% subjects reported some form of visual problem. Fourty four percent of microscope users felt stressed with long working hours on microscope. Conclusions: The most common occupational concerns of microscope users were musculoskeletal problems of neck and back regions, eye fatigue, aggravation of ametropia, headache, stress due to long working hours and anxiety during or after microscope use. There is an immediate need for increasing awareness about the various occupational hazards and their irreversible effects to prevent them.

Cannabis agriculture is a multi-billion dollar industry in the United States that is changing rapidly with policy liberalization. Anecdotal observations fuel speculation about associated environmental impacts, and there is an urgent need for systematic empirical research. An example from Humboldt County California, a principal cannabis-producing region, involved digitizing 4428 grow sites in 60 watersheds with Google Earth imagery. Grows were clustered, suggesting disproportionate impacts in ecologically important locales. Sixty-eight percent of grows were >500 m from developed roads, suggesting risk of landscape fragmentation. Twenty-two percent were on steep slopes, suggesting risk of erosion, sedimentation, and landslides. Five percent were cannabis agriculture documented in our study demands that it be regulated and researched on par with conventional agriculture.

Fortney, Jennifer T.; Halperin, Edward C.; Hertz, Caryn M.; Schulman, Scott R.

1999-01-01

Background: For very young patients, anesthesia is often required for radiotherapy. This results in multiple exposures to anesthetic agents over a short period of time. We report a consecutive series of children anesthetized for external beam radiation therapy (EBRT). Methods: Five hundred twelve children ≤ 16 years old received EBRT from January 1983 to February 1996. Patient demographics, diagnosis, anesthesia techniques, monitoring, airway management, complications, and outcome were recorded for the patients requiring anesthesia. Results: One hundred twenty-three of the 512 children (24%) required 141 courses of EBRT with anesthesia. Anesthetized patients ranged in age from 20 days to 11 years (mean 2.6 ± 1.8 ). The frequency of a child receiving EBRT and requiring anesthesia by age cohort was: ≤ 1 year (96%), 1-2 years (93%), 2-3 years (80%), 3-4 years (51%), 4-5 years (36%), 5-6 years (13%), 6-7 years (11%), and 7-16 years (0.7%). Diagnoses included: primary CNS tumor (28%), retinoblastoma (27%), neuroblastoma (20%), acute leukemia (9%), rhabdomyosarcoma (6%), and Wilms' tumor (4%). Sixty-three percent of the patients had been exposed to chemotherapy prior to EBRT. The mean number of anesthesia sessions per patient was 22 ± 16. Seventy-eight percent of the treatment courses were once daily and 22% were twice daily. Anesthesia techniques included: short-acting barbiturate induction + inhalation maintenance (21%), inhalation only (20%), ketamine (19%), propofol only (12%), propofol induction + inhalation maintenance (7%), ketamine induction + inhalation maintenance (6%), ketamine or short-acting barbiturate induction + inhalation maintenance (6%). Monitoring techniques included: EKG (95%), O 2 saturation (93%), fraction of inspired O 2 (57%), and end-tidal CO 2 (55%). Sixty-four percent of patients had central venous access. Eleven of the 74 children with a central line developed sepsis (15%): 6 of the 11 were anesthetized with propofol (55%), 4 with a

We evaluate the frequency and accuracy of health care workers verifying patient identity before performing common tasks. The study included prospective, simulated patient scenarios with an eye-tracking device that showed where the health care workers looked. Simulations involved nurses administering an intravenous medication, technicians labeling a blood specimen, and clerks applying an identity band. Participants were asked to perform their assigned task on 3 simulated patients, and the third patient had a different date of birth and medical record number than the identity information on the artifact label specific to the health care workers' task. Health care workers were unaware that the focus of the study was patient identity. Sixty-one emergency health care workers participated--28 nurses, 16 technicians, and 17 emergency service associates--in 183 patient scenarios. Sixty-one percent of health care workers (37/61) caught the identity error (61% nurses, 94% technicians, 29% emergency service associates). Thirty-nine percent of health care workers (24/61) performed their assigned task on the wrong patient (39% nurses, 6% technicians, 71% emergency service associates). Eye-tracking data were available for 73% of the patient scenarios (133/183). Seventy-four percent of health care workers (74/100) failed to match the patient to the identity band (87% nurses, 49% technicians). Twenty-seven percent of health care workers (36/133) failed to match the artifact to the patient or the identity band before performing their task (33% nurses, 9% technicians, 33% emergency service associates). Fifteen percent (5/33) of health care workers who completed the steps to verify patient identity on the patient with the identification error still failed to recognize the error. Wide variation exists among health care workers verifying patient identity before performing everyday tasks. Education, process changes, and technology are needed to improve the frequency and accuracy of

Remission of severe restless legs syndrome and periodic limb movements in sleep after bilateral excision of multiple foot neuromas: a case report

Directory of Open Access Journals (Sweden)

Lettau Ludwig A

2010-09-01

Full Text Available Abstract Introduction Restless legs syndrome is a sensorimotor neurological disorder characterized by an urge to move the legs in response to uncomfortable leg sensations. While asleep, 70 to 90 percent of patients with restless legs syndrome have periodic limb movements in sleep. Frequent periodic limb movements in sleep and related brain arousals as documented by polysomnography are associated with poorer quality of sleep and daytime fatigue. Restless legs syndrome in middle age is sometimes associated with neuropathic foot dysesthesias. The causes of restless legs syndrome and periodic limb movements in sleep are unknown, but the sensorimotor symptoms are hypothesized to originate in the central nervous system. We have previously determined that bilateral forefoot digital nerve impingement masses (neuromas may be a cause of both neuropathic foot dysesthesias and the leg restlessness of restless legs syndrome. To the best of our knowledge, this case is the first report of bilateral foot neuromas as a cause of periodic limb movements in sleep. Case presentation A 42-year-old Caucasian woman with severe restless legs syndrome and periodic limb movements in sleep and bilateral neuropathic foot dysesthesias was diagnosed as having neuromas in the second, third, and fourth metatarsal head interspaces of both feet. The third interspace neuromas represented regrowth (or 'stump' neuromas that had developed since bilateral third interspace neuroma excision five years earlier. Because intensive conservative treatments including repeated neuroma injections and various restless legs syndrome medications had failed, radical surgery was recommended. All six neuromas were excised. Leg restlessness, foot dysesthesias and subjective sleep quality improved immediately. Assessment after 18 days showed an 84 to 100 percent reduction of visual analog scale scores for specific dysesthesias and marked reductions of pre-operative scores of the Pittsburgh sleep

Federally qualified health centers provide care to medically underserved populations, the same individuals often underrepresented in the electoral process. These centers are unique venues to access patients for voter registration services. We undertook a clinician-led, nonpartisan voter registration drive within 2 university-affiliated federally qualified health centers in the Bronx, New York. Patients were approached by voter registration volunteers in clinic waiting areas during a 12-week period. Volunteers directly engaged with 304 patients. Of the 128 patients who were eligible and not currently registered, 114 (89%) registered to vote through this project. This number corresponded to 38% of all patients engaged. Sixty-five percent of new registrants were aged younger than 40 years. This project was successful in registering clinic patients to vote. Clinics are not only health centers, but also powerful vehicles for bringing a voice to civically disenfranchised communities. © 2014 Annals of Family Medicine, Inc.

The simulation of the CI (cochlear implant) signal presents a degraded representation of each musical instrument, which makes recognition difficult. To examine the efficiency and effectiveness of three types of training on recognition of musical instruments as presented through simulations of the sounds transmitted through a CI. Participants were randomly assigned to one of three training conditions: repeated exposure, feedback, and direct instruction. Sixty-six adults with normal hearing. Each participant completed three training sessions per week, over a five-week time period, in which they listened to the CI simulations of eight different musical instruments. Analyses on percent of instruments identified correctly showed statistically significant differences between recognition accuracy of the three training conditions (p different types of training are differentially effective with regard to improving recognition of musical instruments presented through a degraded signal, which has practical implications for the auditory rehabilitation of persons who use cochlear implants.

Gaughan, John B.; Lees, Angela M.; Sejian, Veerasamy

2017-10-01

Animal biometeorology (insects excluded) has been part of the International Journal of Biometeorology since its inception in 1958. Over the first 60 years of the journal, 480 animal biometeorology papers were published. Thus, approximately 14% of published papers dealt with animals. Over the first 60 years, data from more than 50 animal species was presented, with the lead authors coming from 48 countries. The two most common species used in animal papers between 1957 and 2016 were cattle (109 papers: 22.7% of all animal papers) and rats (96 papers: 20.0% of all animal papers). Although cattle and rats dominated, the species in the most cited paper (240 citations) was chickens, followed by bird migration (155 citations), and general livestock (118 citations). Overall, five papers exceeded 100 citations, and a further two exceeded 200 citations. In the last decade, 126 animal papers were published (26% of all animal papers). Many of these papers had a focus on livestock production in developing countries especially Brazil.

Sixty Years of Casting Research

Campbell, John

2015-11-01

The 60 years of solidification research since the publication of Chalmer's constitutional undercooling in 1953 has been a dramatic advance of understanding which has and continues to be an inspiration. In contrast, 60 years of casting research has seen mixed fortunes. One of its success stories relates to improvements in inoculation of gray irons, and another to the discovery of spheroidal graphite iron, although both of these can be classified as metallurgical rather than casting advances. It is suggested that true casting advances have dated from the author's lab in 1992 when a critical surface turbulence condition was defined for the first time. These last 20 years have seen the surface entrainment issues of castings developed to a sufficient sophistication to revolutionize the performance of light alloy and steel foundries. However, there is still a long way to go, with large sections of the steel and Ni-base casting industries still in denial that casting defects are important or even exist. The result has been that special ingots are still cast poorly, and shaped casting operations have suffered massive losses. For secondary melted and cast materials, electro-slag remelting has the potential to be much superior to expensive vacuum arc remelting, which has cost our aerospace and defense industries dearly over the years. This failure to address and upgrade our processing of liquid metals is a serious concern, since the principle entrainment defect, the bifilm, is seen as the principle initiator of cracks in metals; in general, bifilms are the Griffith cracks that initiate failures by cracking. A new generation of crack resistant metals and engineering structures can now be envisaged.

Cancellation of surgery close to scheduled time causes a waste of healthcare resources. The current study analyzes surgery cancellations occurring after the patient has been prepared for the operating room, in order to see whether improvements in the surgery planning process may reduce the number of cancellations. In a retrospective chart review of operating room surgery cancellations during the period from 2006 to 2011, cancellations were divided into the following categories: inadequate NPO; medical; surgical; system; airway; incomplete evaluation. The relative use of these reasons in relation to patient age and surgical department was then evaluated. Forty-one percent of cancellations were for other than medical reasons. Among these, 17.7% were due to incomplete evaluation, and 8.2% were due to family issues. Sixty seven percent of cancelled cases eventually received surgery. The relative use of individual reasons for cancellation varied with patient age and surgical department. The difference between cancellations before and after anesthesia was dependent on the causes of cancellation, but not age, sex, ASA status, or follow-up procedures required. Almost half of the cancellations were not due to medical reasons, and these cancellations could be reduced by better administrative and surgical planning and better communication with the patient and/or his family.

Somatosensory loss following stroke is common, with negative consequences for functional outcome. However, existing studies typically do not include quantitative measures of discriminative sensibility. The aim of this study was to quantify the proportion of stroke patients presenting with discriminative sensory loss of the hand in the post-acute rehabilitation phase. Prospective cohort study of stroke survivors presenting for rehabilitation. Fifty-one consecutive patients admitted to a metropolitan rehabilitation centre over a continuous 12-month period who met selection criteria. Quantitative measures of touch discrimination and limb position sense, with high re-test reliability, good discriminative test properties and objective criteria of abnormality, were employed. Both upper limbs were tested, in counterbalanced order. Impaired touch discrimination was identified in the hand contralateral to the lesion in 47% of patients, and in the ipsilesional hand in 16%. Forty-nine percent showed impaired limb position sense in the contralesional limb and 20% in the ipsilesional limb. Sixty-seven percent demonstrated impairment of at least one modality in the contralesional limb. Ipsilesional impairment was less severe. Discriminative sensory impairment was quantified in the contralesional hand in approximately half of stroke patients presenting for rehabilitation. A clinically significant number also experienced impairment in the ipsilesional "unaffected" hand.

The number of Iranian immigrants in Canada has been increasing since 1979. This study is the result of a review of 111 charts of Iranian patients who were referred for psychiatric treatment between 1985 and 1988. Ninety-eight percent of them arrived in Canada after the Iranian revolution, which started in 1979, and the Iran-Iraq war of 1980. Ten percent were experiencing trauma as a result of their involvement with the revolutionary government or the war. The symptoms were in accordance with the DSM-III-R criteria for post-traumatic stress disorder. Sixty percent met the criteria for adjustment disorder with depressed or anxious mood. Six percent had been subjected to physical and psychological torture and confinement. This is the first study that looks at the prevalence of psychiatric illness among Iranians and illustrates the effect of migration and displacement in the integrity of the psychic life of this population.

They included 46 patients of type III baldness, 23 patients of type III (vertex baldness, and 31 patients of type IV baldness. It needed 3 sittings in type III as well as type III (vertex patients, whereas type IV patients needed 4 sittings for cosmetically acceptable results. Sixty percent patients of type III (including type III vertex showed excellent results; whereas 24 percent patients showed good response. Thirty-four percent patients of type IV got excellent cosmetic appearance; whereas, good results could be obtained in 17 percent patients. The reasons for poor results in certain patients were poor density of hair at donor sites and poor growth of hair in some of the transplanted plugs.

Full Text Available The aim of this work was to evaluate the effects of storage period and treatement with hot water at 50ºC or scarification on dormancy break down on Passiflora mucronata seeds. The storage periods were 0, 1, 4 and 12 months. The seeds were sown onto Germitest paper roll and incubated in a germination chamber under 20ºC/8h-30ºC/16h alternate temperature, at 16-h photoperiod (fluorescent light at 32 mol m-2 s-1 irradiance. The percent germination was evaluated, and the seeds germinated on moistened Germitest paper rolls in distilled water at a ratio of two and a half times the paper weight. The seeds were transferred to a germination chamber with alternating temperatures of 20-30º C and photoperiod of 16 h until the end of the experiment at 31 days. The experiment was analyzed as completely randomized designed with four replications, in which each plot was constituted by 50 seeds. The storage periods had significant effect on the variable studied, where the higher germination was obtained at freshly harvested seeds. At the first month of evaluation the germination decreased. After 4 and 12 months of storage, no germination was detected. The treatment with hot water at 50º or scarification favored the germination of the Passiflora seeds stored by one and four months, however even with the stimulus of the treatments, the values of final germination were low. The treatments were not efficient to stimulate the seed germination stored by 12 months.

Bounded and Periodic Solutions of Semilinear Impulsive Periodic System on Banach Spaces

2008-01-01

Full Text Available Abstract A class of semilinear impulsive periodic system on Banach spaces is considered. First, we introduce the -periodic PC-mild solution of semilinear impulsive periodic system. By virtue of Gronwall lemma with impulse, the estimate on the PC-mild solutions is derived. The continuity and compactness of the new constructed Poincaré operator determined by impulsive evolution operator corresponding to homogenous linear impulsive periodic system are shown. This allows us to apply Horn's fixed-point theorem to prove the existence of -periodic PC-mild solutions when PC-mild solutions are ultimate bounded. This extends the study on periodic solutions of periodic system without impulse to periodic system with impulse on general Banach spaces. At last, an example is given for demonstration.

Anaphylaxis is a severe, life-threatening situation. However, little is known about real-life anaphylactic management in children, especially in kindergarten and school settings, where a large number of anaphylaxes take place. Parents, school teachers and child-care providers of 86 primary schools and kindergartens in the city of Dresden, Germany, received questionnaires to report their experience with anaphylaxis in children. The main foci of interest were symptoms, allergens, sites of occurrence, acute treatment and emergency sets. Out of 6352 returned questionnaires, 87 cases of anaphylaxis were identified. Prevalence was calculated at 1.5%. Average age of the patients was 7 years, 58% were boys. The majority of reactions occurred at home (67%/58 children). Fourty seven percent (41 children) had recurrent episodes of anaphylaxis. Eighty two percent (71 children) showed cutaneous symptoms, 40% (35 children) respiratory symptoms, 29% (25 children) gastrointestinal symptoms, and 3.4% (3 children) cardiovascular symptoms. Fourty seven percent were classified as mild reactions. Foods were the most common cause (60%/52 cases). Out of these 52, tree-nuts (23%/12 cases) and peanuts (16%/8 cases) were the most frequent triggers. Sixty percent (52 cases) of reactions were treated by a physician, 35% (30 cases) were treated by non-medical professionals only. Fifty one percent (44 children) received antihistamines, 37% (32 children) corticosteroids, 1% (1 child) intramuscular adrenaline. Sixty one percent of children (53 cases) received an emergency kit. Content were corticosteroids (70%/37 cases) and antihistamines (62%/33 cases). Adrenaline auto-injectors were prescribed to 26% (14 cases). Concerning school and kindergarten-staff, 13% of the child-care providers had no knowledge about the emergency kit's content, compared to 34% of teachers. This study might support the impression of severe under-treatment of anaphylactic children in the use of adrenaline and prescription

Over the past few decades, the geographical distribution of emissions of substances that alter the atmospheric energy balance has changed due to economic growth and air pollution regulations. Here, we show the resulting changes to aerosol and ozone abundances and their radiative forcing using recently updated emission data for the period 1990-2015, as simulated by seven global atmospheric composition models. The models broadly reproduce large-scale changes in surface aerosol and ozone based on observations (e.g. 1 to 3 percent per year in aerosols over the USA and Europe). The global mean radiative forcing due to ozone and aerosol changes over the 1990-2015 period increased by 0.17 plus or minus 0.08 watts per square meter, with approximately one-third due to ozone. This increase is more strongly positive than that reported in IPCC AR5 (Intergovernmental Panel on Climate Change Fifth Assessment Report). The main reasons for the increased positive radiative forcing of aerosols over this period are the substantial reduction of global mean SO2 emissions, which is stronger in the new emission inventory compared to that used in the IPCC analysis, and higher black carbon emissions.

Entropy method of measuring and evaluating periodicity of quasi-periodic trajectories

Ni, Yanshuo; Turitsyn, Konstantin; Baoyin, Hexi; Junfeng, Li

2018-06-01

This paper presents a method for measuring the periodicity of quasi-periodic trajectories by applying discrete Fourier transform (DFT) to the trajectories and analyzing the frequency domain within the concept of entropy. Having introduced the concept of entropy, analytical derivation and numerical results indicate that entropies increase as a logarithmic function of time. Periodic trajectories typically have higher entropies, and trajectories with higher entropies mean the periodicities of the motions are stronger. Theoretical differences between two trajectories expressed as summations of trigonometric functions are also derived analytically. Trajectories in the Henon-Heiles system and the circular restricted three-body problem (CRTBP) are analyzed with the indicator entropy and compared with orthogonal fast Lyapunov indicator (OFLI). The results show that entropy is a better tool for discriminating periodicity in quasiperiodic trajectories than OFLI and can detect periodicity while excluding the spirals that are judged as periodic cases by OFLI. Finally, trajectories in the vicinity of 243 Ida and 6489 Golevka are considered as examples, and the numerical results verify these conclusions. Some trajectories near asteroids look irregular, but their higher entropy values as analyzed by this method serve as evidence of frequency regularity in three directions. Moreover, these results indicate that applying DFT to the trajectories in the vicinity of irregular small bodies and calculating their entropy in the frequency domain provides a useful quantitative analysis method for evaluating orderliness in the periodicity of quasi-periodic trajectories within a given time interval.

Thallium myocardial scintigraphy (TMS) is used for diagnosis of viability in infarcted myocardium before coronary revascularization. Underestimation of viability by TMS has been reported by many investigators. To evaluate viability precisely, thallium re-injection method or 24 hour delayed imaging is performed. However, these techniques are not convenient and are difficult to perform in clinical practice. Percent T1-uptake method was developed for predicting myocardial viability. To evaluate usefulness of this method, TMS was performed before and after PTCA in 23 patients with myocardial infarction. Left ventricle was divided into 3 layers, then each layer was divided into 4 segments (12 segments in total). Forth three segments showed recovery of perfusion on TMS after PTCA. Viability in infarcted myocardium is predicted by 1) redistribution (RD), 2) %T1-uptake≥45% on the image immediately after exercise (TE), and 3) %T1-uptake≥45% on delayed image (TD). Sensitivity was RD: 60%, TE: 90% and TD: 95% (p<0.001 vs. RD). Specificity was RD: 74%, TE: 68%, and TD: 60% (NS). Predictive accuracy (PA) was RD: 69%, TE: 77%, TD: 73% (NS). Compared with RD, %T1-uptake, either TE or TD, increased sensitivity with slightly improved PA, but decreased specificity slightly. Therefore %T1-uptake would be a sensitive and useful predictor to find patients who are most likely to benefit from re-vascularization. (author)

Chamov Aleksey Nikolaevich

2016-04-01

Full Text Available In the article the author considers a problem of an optimal way of borrowing during the pre-crisis period (deciding between ruble and foreign currency borrowings. It is obvious that during the period of stable economic growth, when currency pair rate (for example, ruble - USA dollar doesn't change significntly, the lower interest rate of foreign currency loans makes them a cheaper way of borrowing. But during a crisis an abrupt growth of currency pair rate can make foreign currency loan a more expensive way of borrowing (as compared to ruble loan. The author suggests a scenario-based method of decision making about an optimal way of borrowing during a pre-crisis period, which affords to calculate a threshold meaning of currency pair rate, after which a foreign currency loan becomes more expensive. Application of the method is illustrated on the example of a situation in a telecommunication sector in Russian Federation during currency crisis of 2014. A detailed analysis if the situation in the sector in the last pre-crisis year (2013 is provided. Structures of debt burdens of the leading companies (Vimpelcom, MTS and Megafon are considered. Percent shares of currency loans, shares of borrowing types and according interest rates are provided. In the conclusion of the article some specific aspects of application of suggested method and potential ways of its improvement are considered.

Commuting periodic operators and the periodic Wigner function

International Nuclear Information System (INIS)

Zak, J

2004-01-01

Commuting periodic operators (CPO) depending on the coordinate x-hat and the momentum p-hat operators are defined. The CPO are functions of the two basic commuting operators exp(i x-hat 2π/a) and exp(i/h p-hat a), with a being an arbitrary constant. A periodic Wigner function (PWF) w(x, p) is defined and it is shown that it is applicable in a normal expectation value calculation to the CPO, as done in the original Wigner paper. Moreover, this PWF is non-negative everywhere, and it can therefore be interpreted as an actual probability distribution. The PWF w(x, p) is shown to be given as an expectation value of the periodic Dirac delta function in the phase plane. (letter to the editor)

Full Text Available Using the forward period analysis (FPA, we obtain the period of a Morse oscillator and mathematical pendulum system, with the accuracy of 100 significant digits. From these results, the long-term [0, 1060] (time unit solutions, ranging from the Planck time to the age of the universe, are computed reliably and quickly with a parallel multiple-precision Taylor series (PMT scheme. The application of FPA to periodic systems can greatly reduce the computation time of long-term reliable simulations. This scheme provides an efficient way to generate reference solutions, against which long-term simulations using other schemes can be tested.

This study evaluated the prevalence of posttraumatic stress disorder (PTSD) and the severity of PTSD symptoms in survivors, rescuers and witnesses of terrorist attacks on Khyber bazaar, Qissa Khawani bazaar, and All Saints Church in Peshawar city area. Cross-sectional survey is carried out on a sample of one hundred survivors, rescuers and witness of terrorist attacks using structured interviews to assess the severity of posttraumatic stress, five months after the attacks. The study period extended from January 24, 2014 to March 24, 2014 which constitutes a total of period of 8 weeks. PTSD symptoms are measured using Posttraumatic Symptom Scale Interview (PSSI) and conferred to a diagnosis of PTSD at 5 months. Additionally, the severity of PTSD symptoms were determined using PSSI scores, severity ranged from 0-51. Of the one hundred survey respondents, 88% were males and 12% were females. Forty percent (40%) had attained 10 years of education, matriculation, but irrespective of the gender or educational status, all had some degree of PTSD. Sixty-six (66%) percent respondents are diagnosed as having moderate PTSD while 11% of the sample suffered from severe PTSD level. Age, gender, occupation and education level did not have any correlation with PTSD development. The contemporary findings indicate that any person who has witnessed or survived catastrophes of terrorist activities like bomb blast or being exposed to suicide attacks is at risk for developing PTSD, and there is necessity to deliver specialized post-disaster mental health facilities to the people having substantial levels of PTSD after calamities of such great intensity.

This study aimed to explore women's interest in web-based treatments for postpartum anxiety and determine the feasibility of reaching women with postpartum anxiety online. Anxiety in the postpartum period is common and often untreated. One innovative approach of offering treatment during this period is through web-based self-help. Assessing women's interest in new treatments, such as a web-based self-help, is an important step prior to development efforts. A cross-sectional online survey was created and promoted for 4 months via unpaid social media posts (Facebook and Twitter). To be eligible, women had to be over the age of 18, live in England, fluent in English, be within 12 months postpartum and self-report at least mild levels of anxiety. A sample of 114 eligible women were recruited. The majority were Caucasian, well-educated, middle-class women. Seventy percent reported moderate or severe anxiety. Sixty-one percent of women expressed interest in web-based postpartum anxiety treatments. Women preferred treatment in a smartphone/tablet application format, presented in brief modules and supported by a therapist via email or chat/instant messaging. Based on the stated preferences of participating women it is recommended that postpartum anxiety web-based treatments include different forms of therapist support and use a flexibly accessible smartphone/tablet application format with content split into short sections. The findings also suggest that unpaid social media can be feasible in reaching women with postpartum anxiety, but additional efforts are needed to reach a more diverse population.

The index of body mass related to stature, (body mass index, BMI, kgm(-2) ), is widely used as a proxy for percent body fat (%BF) in cross-sectional and longitudinal investigations. BMI does not distinguish between lean and fat mass and in children, the cross-sectional relationship between %BF and BMI changes with age and sex. While BMI increases linearly with age from age 8 to 12 years in both boys and girls, %BF plateaus off between 10 and 12 years. Repeated measures in children show a systematic decrease in %BF for any given BMI from age 8 to 10 to 12 years. Because changes in BMI misrepresent changes in %BF, its use as a proxy of %BF should be avoided in longitudinal studies in this age group. Body mass index (BMI, kgm(-2) ) is commonly used as an indicator of pediatric adiposity, but with its inability to distinguish changes in lean and fat mass, its use in longitudinal studies of children requires careful consideration. To investigate the suitability of BMI as a surrogate of percent body fat (%BF) in pediatric longitudinal investigations. In this longitudinal study, healthy Australian children (256 girls and 278 boys) were measured at ages 8.0 (standard deviation 0.3), 10.0 and 12.0 years for height, weight and percent body fat (%BF) by dual-energy X-ray absorptiometry. The patterns of change in the means of %BF and BMI were different (P < 0.001). While mean BMI increased linearly from 8 to 12 years of age, %BF did not change between 10 and 12 years. Relationships between %BF and BMI in boys and girls were curvilinear and varied with age (P < 0.001) and gender (P < 0.001); any given BMI corresponding with a lower %BF as a child became older. Considering the divergence of temporal patterns of %BF and BMI between 10 and 12 years of age, employment of BMI as a proxy for %BF in absolute or age and sex standardized forms in pediatric longitudinal investigations is problematical. © 2013 The Authors.

Elimination of mercury in health care facilities.

Science.gov (United States)

2000-03-01

Mercury is a persistent, bioaccumulative toxin that has been linked to numerous health effects in humans and wildlife. It is a potent neurotoxin that may also harm the brain, kidneys, and lungs. Unborn children and young infants are at particular risk for brain damage from mercury exposure. Hospitals' use of mercury in chemical solutions, thermometers, blood pressure gauges, batteries, and fluorescent lamps makes these facilities large contributors to the overall emission of mercury into the environment. Most hospitals recognize the dangers of mercury. In a recent survey, four out of five hospitals stated that they have policies in place to eliminate the use of mercury-containing products. Sixty-two percent of them require vendors to disclose the presence of mercury in chemicals that the hospitals purchase. Only 12 percent distribute mercury-containing thermometers to new parents. Ninety-two percent teach their employees about the health and environmental effects of mercury, and 46 percent teach all employees how to clean up mercury spills. However, the same study showed that many hospitals have not implemented their policies. Forty-two percent were not aware whether they still purchased items containing mercury. In addition, 49 percent still purchase mercury thermometers, 44 percent purchase mercury gastrointestinal diagnostic equipment, and 64 percent still purchase mercury lab thermometers.

To investigate the knowledge and attitudes of Thai dental practitioners regarding patients with HIV, a cross-sectional study using self-administered questionnaires was conducted. The questionnaires requested demographic information and included questions evaluating the knowledge and attitude of dental practitioners towards HIV. The results were analyzed using Scheffe method for multiple comparisons at the 95 percent confidence level. Out of 1,200 questionnaires sent, 446 questionnaires were returned (response rate 37.2 percent). The subjects included final (sixth)-year dental students (11.9 percent), general dentists (29.1 percent), specialist dentists (15.5 percent), dental hygienists (30.5 percent), and dental assistants (13 percent). More than 80 percent of the dental practitioners correctly answered the questions testing their basic knowledge of HIV such as routes of transmission and common opportunistic infections. However, knowledge about HIV pathogenesis, complications, and advances in HIV management was lacking. Dental hygienists and dental assistants had statistically significant lower scores in knowledge about HIV than other groups. Sixty-seven percent of dental practitioners said they feel worried when treating patients with HIV, and 20.4 percent said they would deny treatment for patients with HIV if possible. While knowledge about HIV may be adequate among dental practitioners in Thailand, greater effort should be put into emphasizing positive attitudes towards patients with HIV.

Colorectal cancer (CRC) is the second most common cause of cancer death in developed countries among men (after lung cancer) and the third most common among women. This study thus examines the long-term trends of CRC mortality in Taiwan. CRC cases were collective between patients aged 30 years or older and younger than 85 years from the Taiwan death registries during 1971-2010. Standard descriptive techniques such as age-standardized mortality rates (ASMR), aural percent change, and age-period-cohort analyses were used. The increase of percentage change by each age group in men was higher than in women. The ASMR of CRC increased 2-fold for men and almost 1.5-fold for women during the periods 1971-1975 and 2006-2010. For age-period-cohort analysis, the estimated mortality rate increased steadily with age in both sexes, and plateaued at 175.29 per 100,000 people for men and 128.14 per 100,000 for women in the 80- to 84-year-old group. Period effects were weak in both sexes. Cohort effects were strong. Between 30 and 59 years of age, the sex ratio showed that the female CRC mortality rate was higher than that of their male counterparts. Conversely, the mortality risk of CRC in men was higher than that in women when they were between 60 and 84 years old. The current findings showed a consistent increase in mortality from CRC over the years. Changes in the patient sex ratio indicated an important etiological role of sex hormones, especially in women aged 60 years or younger.

Hayes, Valérie Y; Schnider, Cristina M; Veys, Jane

2003-06-01

This was a multi-site, 128-subject, bilateral crossover study to evaluate subjective comfort and slit-lamp findings with 1-day disposable contact lenses in a population of allergy sufferers during periods when allergen levels were elevated. The study involved 1-month of single-use daily wear with a 1-day disposable test lens (1. DAY ACUVUE Brand Contact Lenses, Johnson & Johnson Vision Care) and 1-month of daily wear with subjects' habitual lenses replaced to their usual replacement schedule. Pollen and mould counts were obtained for each site 1 week prior to the study and twice weekly throughout the study period. Subjective comfort and slit-lamp findings were recorded at baseline and after 1-month's wear of each modality. Sixty-seven percent of subjects agreed that the 1-day disposable lenses provided improved comfort when compared to the lenses they wore prior to the study, compared with 18% agreeing that the new pair of habitual lenses provided improved comfort. The 1-day disposable lenses showed greater improvement in slit-lamp findings from baseline than new habitual lenses. The use of 1-day disposable lenses is an effective strategy for managing allergy-suffering contact lens wearers.

Full Text Available A study on the phlebotomine sand fly fauna in Belo Horizonte city, state of Minas Gerais, Brazil, was carried out. From April 2001 to March 2003, monthly systematic collections were performed in three houses from each of the nine regions of the city, using CDC light traps for four consecutive days. The traps were set into the houses and in peridomestic areas totaling 54 traps. A number of 3871 sand fly specimens of the genera Lutzomyia and Brumptomyia were collected. Sixty eight percent of the specimens were L. longipalpis and 16% L. whitmani, insect vectors of visceral and American cutaneous leishmaniasis, respectively. Environmental factors such as temperature, humidity, and frequency of precipitation suggest that the number of insects increases after rainy periods. During the same period mentioned above, seasonal captures were carried out in parks and green areas of Belo Horizonte, using Shannon trap. A total of 579 phlebotomine sand flies were collected from which 398 (68.7% were females with the predominance of L. whitmani and L. monticola. Those specimens were used for natural infection examination, by polymerase chain reaction. No Leishmania DNA was present in any of the specimens tested.

Classical trajectories are calculated for two Hamiltonian systems with ring shaped potentials. Both systems are super-integrable, but not maximally super-integrable, having four globally defined single-valued integrals of motion each. All finite trajectories are quasi-periodical; they become truly periodical if a commensurability condition is imposed on an angular momentum component

1976-01-01

Because of the physical and radiobiologic differences between 125 I and 131 I, a trial using 125 I to treat hyperthyroidism was undertaken in the hope of controlling hyperthyroidism without causing subsequent hypothyroidism. Three hundred fifty-five patients with diffuse toxic goitres were treated and have been under review for an average of 49.4 months: 63.4 percent are euthyroid, 33.5 percent are hypothyroid, and 3.1 percent remain hyperthyroid. Different groups of patients received a wide range of doses of 125 I (4.0 to 56.0 mCi), and the lowest incidence of hypothyroidism (23 percent) was in the group that received between 6.0 and 10.5 mCi. Sixty-three percent of the patients whose initial dose was greater than 20.0 mCi are hypothyroid. Persistent hyperthyroidism was common in patients who received small doses. Because of the high incidence of posttreatment hypothyroidism in this series and because 131 I has stood the test of time, we believe that 131 I is the radionuclide of choice for the routine treatment of hyperthyroidism

Privately-funded addiction treatment programs were surveyed to increase understanding of assessment and current treatment options for patients with co-occurring substance use and eating disorders. Data were collected from face-to-face interviews with program administrators of a nationally representative sample of 345 private addiction treatment programs. Although the majority of programs reported screening for eating disorders, programs varied in screening instruments used. Sixty-seven percent reported admitting cases of low severity. Twenty-one percent of programs attempt to treat eating disorders. These results highlight the need for education of addiction treatment professionals in assessment, referral and treatment of eating disorders. PMID:21477048

A Patterns of Care Study examined the records of patients with thoracic esophageal cancer treated with radiotherapy and surgery in 1995 through 1997. Thirty-one percent of patients received preoperative radiotherapy; 61% of these received chemotherapy. Sixty six percent of patients received postoperative radiotherapy. Significant variables for overall survival in multivariate analysis include presence of macroscopic residual tumors (risk ratio=2.66), sex female (0.49), photon energy higher than 4 MV (0.50), Karnofsky performance status greater than 70 (0.55) and the use of chemotherapy (1.64). The value of preoperative concurrent chemotherapy and radiotherapy should be tested in a randomized trial. (author)

Computerized physician order entry is a required feature for hospitals seeking to demonstrate meaningful use of electronic medical record systems and qualify for federal financial incentives. A national sample of sixty-two hospitals voluntarily used a simulation tool designed to assess how well safety decision support worked when applied to medication orders in computerized order entry. The simulation detected only 53 percent of the medication orders that would have resulted in fatalities and 10-82 percent of the test orders that would have caused serious adverse drug events. It is important to ascertain whether actual implementations of computerized physician order entry are achieving goals such as improved patient safety.

To investigate the responses of the dental student body in the first three years of outreach education (2010-13) at the University of Portsmouth Dental Academy in the areas of integrated team work and use of a current NHS contact. Use of a questionnaire to allow both quantitative and qualitative data to be obtained, administered to the three cohorts of students at the end of their longitudinal attendance at the Academy in their final year of education at King's College London Dental Institute. Data were obtained from 227 students which represented a 95% return rate. Sixty-four percent of students strongly agreed with both statements: 'I am confident with working with a dental nurse' and 'I now understand properly the scope of practice of dental hygiene-therapists'. Sixty-seven percent strongly agreed with the statement 'I have had useful experience of working in NHS primary care during the final year'. Eighty percent either strongly agreed or agreed with the statement 'My experience of real Units of Dental Activity and Key Performance Indicators has encouraged me to positively consider NHS high street dentistry as a career option'. Within the limitations of this study the dental students reported having gained useful experience of working in integrated team care dentistry. They expressed strong support for the education that is being delivered in an outreach environment and, most importantly, the student body was looking forward to entering general dental practice in the UK.

The objectives of this study are to assess: (a) the prevalence of vitamin D deficiency among new patients attending rheumatology outpatient departments, (b) the age profile of these low vitamin D patients and (c) whether any diagnostic category had a particularly high number of vitamin D-deficient patients. All new patients seen consecutively in general rheumatology clinics between January to June 2007 inclusive were eligible to partake in this study, and 231 out of 264 consented to do so. Parathyroid hormone, 25-hydroxyvitamin D, creatinine, calcium, phosphate, albumin and alkaline phosphatase levels were measured. We defined vitamin D deficiency as <\\/=53 nmol\\/l and severe deficiency as <\\/=25 nmol\\/l. Overall, 70% of 231 patients had vitamin D deficiency, and 26% had severe deficiency. Sixty-five percent of patients aged >\\/=65 and 78% of patients aged <\\/=30 years had low vitamin D levels. Vitamin D deficiency in each diagnostic category was as follows: (a) inflammatory joint diseases\\/connective tissue diseases (IJD\\/CTD), 69%; (b) soft tissue rheumatism, 77%; (c) osteoarthritis, 62%; (d) non-specific musculoskeletal back pain, 75% and (e) osteoporosis, 71%. Seasonal variation of vitamin D levels was noted in all diagnostic groups apart from IJD\\/CTD group, where the degree of vitamin D deficiency persisted from late winter to peak summer. Very high prevalence of vitamin D deficiency was noted in all diagnostic categories (p = 0.006), and it was independent of age (p = 0.297). The results suggest vitamin D deficiency as a possible modifiable risk factor in different rheumatologic conditions, and its role in IJD\\/CTD warrants further attention.

Full Text Available Abstract Background From the viewpoint of human physiological adaptability, we previously investigated seasonal variation in the amount of unabsorbed dietary carbohydrates from the intestine after breakfast in Japanese, Polish and Thai participants. In this investigation we found that there were significant seasonal variations in the amount of unabsorbed dietary carbohydrates in Japanese and Polish participants, while we could not find significant seasonal variation in Thai participants. These facts prompted us to examine seasonal variations in the respiratory quotient after an overnight fast (an indicator of the ratio of carbohydrate and fat oxidized after the last meal with female university students living in Osaka (Japan, Poznan (Poland and Chiang Mai (Thailand. Methods We enrolled 30, 33 and 32 paid participants in Japan, Poland and Thailand, respectively, and measurements were taken over the course of one full year. Fasting respiratory quotient was measured with the participants in their postabsorptive state (after 12 hours or more fasting before respiratory quotient measurement. Respiratory quotient measurements were carried out by means of indirect calorimetry using the mixing chamber method. The percent body fat was measured using an electric bioelectrical impedance analysis scale. Food intake of the participants in Osaka and Poznan were carried out by the Food Frequency Questionnaire method. Results There were different seasonal variations in the fasting respiratory quotient values in the three different populations; with a significant seasonal variation in the fasting respiratory quotient values in Japanese participants, while those in Polish and Thai participants were non-significant. We found that there were significant seasonal changes in the percent body fat in the three populations but we could not find any significant correlation between the fasting respiratory quotient values and the percent body fat. Conclusions There were

The purpose of this study was to define patterns of injury and treatment for condylar and subcondylar fractures and evaluate short-term outcomes in the pediatric population. A retrospective chart review was performed on pediatric patients with mandibular condylar fractures who presented between 1990 and 2010. Computed tomographic imaging was reviewed for all patients to assess fracture characteristics. Mandibular fractures were codified using the Strasbourg Osteosynthesis Research Group and Lindahl classification methods. Sixty-four patients with 92 condylar fractures were identified. Of these patients, 29 had isolated condylar fracture and 35 had a condylar fracture associated with an additional mandibular arch fracture. The most common fracture patterns were diacapitular fracture in the Strasbourg Osteosynthesis Research Group system (n = 46) and vertical condylar head fracture in the Lindahl system (n = 14). Condylar fracture with additional mandibular arch fractures were treated with maxillomandibular fixation more often than patients with condylar fracture [n = 40 (74.1 percent) versus n = 14 (25.9 percent); p = 0.004]. No condylar fracture was treated in an open fashion. Forty-three patients returned for follow-up. The median follow-up period was 81 days (interquartile range, 35 to 294 days). Ten patients had complications (23.3 percent). The most common complication was malocclusion (n = 5). Nine of 10 patients with complications had condylar fracture with an additional mandibular arch fracture. Closed treatment of condylar fractures yields satisfactory results in pediatric patients. Pediatric patients with condylar fractures combined with additional arch fractures experience a higher rate of unfavorable outcomes.

Tattooing is a very popular form of body modification among young people. However, this kind of procedure entails the risk of various health complications. The objective of the study was to evaluate the students' knowledge about contraindications, complications, and health risks that skin tattooing may cause. Additionally, the purpose of the study was to assess how the profile of education (medical vs nonmedical) impacts on the knowledge of the respondents. We surveyed a group of 1199 people, of which 326 (27%) had tattoos. The base of the study is an anonymously filled, author's online survey consisting of 25 questions. Eighty six percent of the students from the Medical University of Gdańsk indicated the risk of HCV virus infection during tattooing, while only 34% of students from other Tricity universities were aware of this danger. Sixty seven percent of people with tattoos felt that having them does not affect any diagnostic and therapeutic procedures. Most of respondents mentioned the tattoo artist (79%) and the Internet (73%) as a source of information before having a tattoo, while only 5% and 8% respondents asked a doctor or read medical literature about it. Fourty nine percent of respondents reported that before the procedure, tattooist failed to ask them about their health condition and medications. Knowledge of students about safety, contraindications, and complications associated with the performance of tattooing is insufficient. As a result, a need for a better education on the topic for both people who are getting tattoos and tattooists appears evident. © 2017 Wiley Periodicals, Inc.

2017-02-01

Idiopathic clubfoot is one of the most common and oldest congenital foot anomalies. There are controversies regarding its optimum management protocol and methodologies to be employed for its functional outcome evaluation. This paper attempts to propose a simple, reasonable and easily reproducible technique of podography for clinical and functional evaluation of clubfoot treated by the popular Ponseti technique. To compare the Foot Bimalleolar (FBM) angle method (podography) and radiography with respect to management of idiopathic clubfoot by Ponseti's Technique and its functional evaluation. Sixty feet of 48 patients with idiopathic clubfoot deformity were assessed in terms of FBM by podography (foot print on paper and FBM angle drawing) and radiologically; before starting treatment, after 6 weeks and at 6 monthly intervals with a maximum follow up period of 4.8 years (Range 1.2 to 4.8 years). Mean age at start of treatment was 1.5 years (2 months to 2.5 years). Functional evaluation was done by Magone's scoring system. After treatment, 92 percent patients had good correction (FBM greater than 70 degrees) which correlated well with post treatment Magone's score of greater than 80 (good to excellent) in nearly 85 percent of cases. Radiologically, talocalcaneal angles in both the views improved in only 60 percent of cases. Radiological criteria show inconsistent correlation with functional outcome for feet treated by Ponseti's Technique. Podography (FBM angle analysis) is a very simple, objective, cost effective, radiation free, easily reproducible and highly reliable clinical criterion for the assessment of deformity correction in club foot by Ponseti's Technique with an excellent correlation with functional outcome.

Upper oesophago-gastro-duodenoscopies (UGI endoscopies) were performed on adult patients who attended Saudi Aramco Health Centre at Al Hasa, Saudi Arabia, between June 1986 and December 1993, with complaint of upper abdominal pain. During this period, three hundred and fifteen (315) patients were examined. Sixty one percent were females and the rest males. Peptic ulcer disease including gastritis was the most common diagnosis made. Helicobacter pylori-like organisms were documented historically in biopsy samples in 113 of 178 (63%) patients. Nearly all were associated with gastritis; no organisms were reported in normal histology specimens. This confirms the association of this organism with gastritis. Gastric cancer suspected radiologically were not confirmed endoscopically or histologically. It is important to endoscope and biopsy for histology suspected gastric cancer and ulcer; a negative result may save the patient from unnecessary surgery, ideally all normal looking gastric mucosa should be biopsied so that histological gastritis is not missed.

1996-09-01

To study the natural history and retinal findings associated with the intraretinal and subretinal fibrovascular tissues that develop in the late phases of bilateral juxtafoveal telangiectasis. The records of 10 patients (11 eyes) with bilateral juxtafoveal telangiectasis who developed these fibrovascular tissues were examined. Throughout the follow-up period (average 44 months), only 2 eyes (18%) lost 2 or more lines of vision; the final visual acuities were similar for the eyes both with and without fibrovascular tissues. Sixty-four percent of fibrovascular tissues showed little to no growth. Eyes with fibrovascular tissue commonly had retinal pigment epithelial hyperplasia (72%), draining retinal venules (82%), and retinal vascular distortion (64%). Fibrovascular tissues of bilateral juxtafoveal telangiectasis have little proliferative potential and minimal effects on visual acuity. Nevertheless, these fibrovascular tissues do remodel over time, leading to retinal vascular distortion. Given these benign findings, the role of laser photocoagulation treatment of these tissues is questionable.

This study assessed exposure to carbon monoxide from gas and wood heater emissions in a sample of 64 households in peri-urban residential areas in Ciudad Juárez, Chihuahua, México. Indoor and outdoor carbon monoxide concentrations and temperatures were monitored for a continuous period of 1 week at 1 and 6-min intervals, respectively. The moving average carbon monoxide concentrations were compared to the World Health Organization (WHO) standards for carbon monoxide. Sixty-seven percent of households with gas heaters and 60% of households with wood heaters exceeded a health-based standard at some point during the monitoring. The difference between indoor and outdoor temperatures was modestly correlated with average carbon monoxide exposure (r=0.35, p-value h standard of 9ppm (odds ratio=5.1, p-value=0.031). These results highlight the need for further efforts to identify and mitigate potentially hazardous carbon monoxide exposures, particularly in moderate-income countries with cooler climates.

We hypothesized that a routine one-stage exchange for treatment of chronically infected total hip replacement (THR) will lead to (1) a higher rate of infection recurrence and (2) a poorer hip outcome than the published rates after two-stage exchange. Sixty-five cases have been treated consecutively with one-stage exchange. All patients have been followed for a period of three to six years or until death or infection recurrence. The five-year rate for infection recurrence was 16%. The five-year survival rate for recurrence of the index infection was 8%. Forty-two percent of the hips had a good or excellent PMA score, and 46% a good or excellent OH score. Routine one-stage exchange was not associated with a higher recurrence rate and a poorer hip function than previously published series of two-stage exchange. Therefore, there is little support to choose two-stage exchange as the routine treatment for management of chronically infected THR.

Sixty-Seven Years of Land-Use Change in Southern Costa Rica.

Full Text Available Habitat loss and fragmentation of forests are among the biggest threats to biodiversity and associated ecosystem services in tropical landscapes. We use the vicinity of the Las Cruces Biological Station in southern Costa Rica as a regional case study to document seven decades of land-use change in one of the most intensively studied sites in the Neotropics. Though the premontane wet forest was largely intact in 1947, a wave of immigration in 1952 initiated rapid changes over a short period. Overall forest cover was reduced during each time interval analyzed (1947-1960, 1960-1980, 1980-1997, 1997-2014, although the vast majority of forest loss (>90% occurred during the first two time intervals (1947-1960, 1960-1980 with an annual deforestation rate of 2.14% and 3.86%, respectively. The rate dropped to 100 km of linear strips of vegetation within a 3 km radius of the station, which may facilitate landscape-level movement for some species. Despite the extent of forest loss, a substantial number of regional landscape-level studies over the past two decades have demonstrated the persistence of many groups of organisms such as birds and mammals. Nonetheless, the continued decline in the quantity and quality of remaining habitat (~30% of remaining forest is secondary, as well as the threat of an extinction debt (or time lag in species loss, may result in the extirpation of additional species if more proactive conservation measures are not taken to reverse current trends-a pattern that reflects many other tropical regions the world over.

Most important etiologic factors in the development of genital prolapse

Directory of Open Access Journals (Sweden)

Mladenović-Segedi Ljiljana

2010-01-01

Full Text Available Introduction The incidence of genital prolapse depends on numerous factors. The contribution of race, gender and genetic factors is significant. However, additional factors of initiation, promotion and decomposition are necessary if a person with the genetic predisposition to genital prolapse begins to suffer from it. At least 50% of parous women are believed to suffer from genital prolapse of various degrees. Moreover, the prevalence of genital prolapse increases with age. The prevalence of genital prolapse is expected to be even higher in the future due to the extension of the lifespan of women worldwide. Objective The aim of this study was to determine the most common etiologic factors in the development of genital prolapse in the population of Serbia. Methods The study was conducted as prospective and included 50 women who underwent surgical treatment due to the problems caused by genital prolapse. Results Mean age of the women was 58.74 years. Twenty percent of the women had the menstrual cycle, while 80% were in menopause. Mean menopause period was 8.88 years. None of the women used hormone replacement therapy. Mean BMI was 27.395 kg/m2. Twenty-eight percent of the women were of normal weight, while 72% of the women were obese (42% were obese and 30% were severely obese. Ninety-eight percent of the women were parous, and mean parity was 2.08. Mean birth weight of neonates was 3682.77 g. Sixty-four percent of the women did physical labour and lifted heavy objects. Conclusion Vaginal childbirth is one of the most important initiating factors. The most significant promoting factor is obesity and heavy labour. Ageing and entering menopause are the most important factors of decomposition as well as the occurrence of clinical manifestations of the pelvic floor dysfunction. .

PERIOD ESTIMATION FOR SPARSELY SAMPLED QUASI-PERIODIC LIGHT CURVES APPLIED TO MIRAS

We develop a nonlinear semi-parametric Gaussian process model to estimate periods of Miras with sparsely sampled light curves. The model uses a sinusoidal basis for the periodic variation and a Gaussian process for the stochastic changes. We use maximum likelihood to estimate the period and the parameters of the Gaussian process, while integrating out the effects of other nuisance parameters in the model with respect to a suitable prior distribution obtained from earlier studies. Since the likelihood is highly multimodal for period, we implement a hybrid method that applies the quasi-Newton algorithm for Gaussian process parameters and search the period/frequency parameter space over a dense grid. A large-scale, high-fidelity simulation is conducted to mimic the sampling quality of Mira light curves obtained by the M33 Synoptic Stellar Survey. The simulated data set is publicly available and can serve as a testbed for future evaluation of different period estimation methods. The semi-parametric model outperforms an existing algorithm on this simulated test data set as measured by period recovery rate and quality of the resulting period–luminosity relations.

Science.gov (United States)

1990-01-01

It is NASA's intent to provide small disadvantaged businesses, including women-owned, historically black colleges and universities and minority education institutions the maximum practicable opportunity to receive a fair proportion of NASA prime and subcontracted awards. Annually, NASA will establish socioeconomic procurement goals including small disadvantaged business goals, with a target of reaching the eight percent level by the end of FY 1994. The NASA Associate Administrators, who are responsible for the programs at the various NASA Centers, will be held accountable for full implementation of the socioeconomic procurement plans. Various aspects of this plan, including its history, are discussed.

2012-01-01

Full Text Available On the sixth day of the tenth month of the eleventh year of the twenty first century, sixty six years after the first confiscation of property after the Second World War, a new law on general restitution of property came to light in Serbia. This play with numbers and words, as the article itself, aims at drawing the attention of legal scholars to the problems surrounding restitution in Serbia within the limits set by the law. Our intention was to point out to the incompleteness and shallowness of the Law by offering a systematic analysis, supported by arguments, of legislation on which the Law on Restitution rests and to propose suggestions that would help overcome difficulties in interpreting certain provisions of the Law, ultimately stating what the law ought to be (de lege ferenda.

salmon. Most fish spent several days in the dam forebay; median forebay residence times were 4.4 d for juvenile steelhead and 5.7 d for juvenile coho salmon. A new radio transmitter model was used during the study period. The transmitter had low detection probabilities on underwater antennas located within the collection system, which prevented us from reporting performance metrics (discovery efficiency, entrance efficiency, retention efficiency) that are traditionally used to evaluate fish collection systems. Most tagged steelhead (98 percent) and coho salmon (84 percent) were detected near the weir box or collection flume entrances during the study period; 39 percent of tagged steelhead and 55 percent of tagged coho salmon were detected at both entrances. Sixty-three percent of the tagged steelhead that were detected at both entrances were first detected at the weir box, compared to 52 percent of the coho salmon. Twelve steelhead and 15 coho salmon detected inside the weir box eventually left the device and were collected in collection flumes or passed the dam. Overall, collection rates were relatively high during the study period. Sixty-five percent of the steelhead and 80 percent of the coho salmon were collected during the study, and most of the remaining fish passed the dam and entered the tailrace (24 percent of steelhead; 13 percent of coho salmon). The remaining 11 percent of steelhead and 7 percent of coho salmon did not pass the dam while their transmitters were operating. We were able to confirm collection of tagged fish at the fish facility using three approaches: (1) detection of radio transmitters in study fish; (2) detection of PIT-tags in study fish; (3) observation of study fish by staff at the fish facility. Data from all three methods were used to develop a multistate mark-recapture model that estimated detection probabilities for the various monitoring methods. These estimates then were used to describe the percent of tagged fish that were collected

The aim of this study was to evaluate spiral multidetector computed tomography (MDCT) angiography using 64-slice technique in the detection of functionally relevant coronary artery stenoses (CAS). Thirty-eight patients (62±11 years, 28 men) with stable angina (26 with suspected and 12 with known coronary artery disease) were investigated using 64-slice MDCT angiography and gated myocardial perfusion SPECT (gated SPECT); a subgroup of 30 patients had additional invasive coronary angiography (ICA). Stenoses with luminal narrowing of ≥50% were defined as ''significant'' in MDCT angiography and ICA. MDCT angiography was compared with gated SPECT and the combination of gated SPECT plus ICA with respect to the detection of functionally relevant CAS. The sensitivity, specificity and negative and positive predictive values of MDCT angiography in detecting reversible perfusion defects on gated SPECT were 63%, 80%, 94% and 32%, respectively, in vessel-based analysis and 71%, 62%, 72% and 60%, respectively, in patient-based analysis. If only reversible perfusion defects on gated SPECT with CAS ≥50% on ICA were considered, the sensitivity, specificity and negative and positive predictive values were, respectively, 85%, 79%, 98% and 33% for vessel-based analysis and 85%, 59%, 83% and 61% for patient-based analysis. Sixty-four slice MDCT angiography failed to predict the functional relevance of CAS, but had a high negative predictive value in the exclusion of functionally relevant CAS in symptomatic patients.

The purpose of this investigation was to examine the drivers of patient retention at dental school clinics from a services marketing perspective. An analysis of patient characteristics at Virginia Commonwealth University School of Dentistry, screened between August 2010 and July 2011 (N=3604), was performed using descriptive statistics, cross-tabulations, and a binary logistic regression. The main findings were that 42 percent of patients in the study were retained and that no response to communication efforts (36 percent) and financial problems (28 percent) constituted the most common reasons for non-retention. Older age, having insurance, and living within a sixty-mile radius were significant drivers of retention (pskills to better service them, and consequently increasing retention. This will lead to providing a continuum of care and student education and to ensuring the sustainability and quality of the school's educational programs.

On complex periodic motions and bifurcations in a periodically forced, damped, hardening Duffing oscillator

International Nuclear Information System (INIS)

Guo, Yu; Luo, Albert C.J.

2015-01-01

In this paper, analytically predicted are complex periodic motions in the periodically forced, damped, hardening Duffing oscillator through discrete implicit maps of the corresponding differential equations. Bifurcation trees of periodic motions to chaos in such a hardening Duffing oscillator are obtained. The stability and bifurcation analysis of periodic motion in the bifurcation trees is carried out by eigenvalue analysis. The solutions of all discrete nodes of periodic motions are computed by the mapping structures of discrete implicit mapping. The frequency-amplitude characteristics of periodic motions are computed that are based on the discrete Fourier series. Thus, the bifurcation trees of periodic motions are also presented through frequency-amplitude curves. Finally, based on the analytical predictions, the initial conditions of periodic motions are selected, and numerical simulations of periodic motions are carried out for comparison of numerical and analytical predictions. The harmonic amplitude spectrums are also given for the approximate analytical expressions of periodic motions, which can also be used for comparison with experimental measurement. This study will give a better understanding of complex periodic motions in the hardening Duffing oscillator.

Full Text Available Abstract Background Early diagnosis of idiopathic scoliosis allows for observation and timely initiation of brace treatment in order to halt progression. School scoliosis screening programs were abolished in Norway in 1994 for lack of evidence that the programs improved outcome and for the costs involved. The consequences of this decision are discussed. Objectives To describe the detection, patient characteristics, referral patterns and treatment of idiopathic scoliosis at a scoliosis clinic during the period 2003–2011, when there was no screening and to compare treatment modalities to the period 1976–1988 when screening was performed. Methods Patient demographics, age at detection, family history, clinical and radiological charts of consecutive patients referred for scoliosis evaluation during the period 2003–2011, were prospectively registered. Patients were recruited from a catchment area of about 500000 teenagers. Maturity was estimated according to Risser sign and menarcheal status. Severity of pain was recorded by a verbal 5-point scale from no pain to pain at all times. Physical and neurological examinations were conducted. The detector and patient characteristics were recorded. Referral patterns of orthopedic surgeons at local hospitals and other health care providers were recorded. Patient data was obtained by spine surgeons. Treatment modalities in the current period were compared to the period 1976–1988. Results We registered 752 patients with late onset juvenile and adolescent idiopathic scoliosis from 2003–2011. There were 644 (86% girls and 108 (14% boys. Mean age at detection was 14.6 (7–19 years. Sixty percent had Risser sign ≥ 3, whilst 74% were post menarche with a mean age at menarche of 13.2 years. Thirty-one percent had a family history of scoliosis. The mean major curve at first consultation at our clinic was 38° (10°-95°. About 40% had a major curve >40°. Seventy-one percent were detected by patients

Full Text Available Background: Studies assessing the prevalence of oral lesions in children and adolescents, particularly in gingiva are scarce in the literature. The aim of the study was to describe the distribution of gingival proliferative lesions based on clinical and histopathological diagnoses in children and adolescents. Materials and Methods: A review of clinical charts of children and adolescents aged between 0 and 18 years old, admitted to the Oral Medicine Outpatient Unit, of Universidade Federal do Paraná, for 15 years (1994–2009 was performed. Results: Six hundred and sixty-nine out of 5,129 patients treated during this period were aged between 0 and 18 years old, and 45 of these had gingival lesions. The largest number of lesions was observed between 11 and 16 years old. The majority of the patients were referred by Curitiba's public health system. Pyogenic granuloma was the most frequent lesion (19 = 42.2%, followed by peripheral giant cell lesion (11 = 24.4%, gingival fibromatosis (10 = 22.2%, and peripheral ossifying fibroma (5 = 11.1%. Conclusion: Gingival proliferative lesions can show similar clinical characteristics. Appropriate clinical and histopathological diagnoses are necessary to guide the healthcare professional to establish the adequate treatment and to estimate the risk of recurrence.

Theoretical growth rates, periods, and pulsation constants for long-period variables

Theoretical values of the growth rate, period, and pulsation constant for the first three radial pulsation modes in red giants (Population II and galactic disk) and supergiants have been derived in the linear, nonadiabatic approximation. The effects of altering the surface boundary conditions, the effective temperature (or mixing length), and the opacity in the outer layers have been explored. In the standard models, the Q-value for the first overtone can be much larger (Q 1 1 roughly-equal0.04); in addition, the Q-value for the fundamental mode is reduced from previous values, as is the period ratio P 0 /P 1 . The growth rate for the fundamental mode is found to increase with luminosity on the giant branch while the growth rate for the first overtone decreases. Dynamical instabilities found in previous adiabatic models of extreme red giants do not occur when nonadiabatic effects are included in the models. In some massive, luminous models, period ratios P 0 /P 1 approx.7 occur when P 0 approx.2000--5000 days; it is suggested that the massive galactic supergiants and carbon stars which have secondary periods Papprox.2000--7000 days and primary periods Papprox.300--700 days are first-overtone pulsators in which the long secondary periods are due to excitation of the fundamental mode. Some other consequences of the present results are briefly discussed, with particular emphasis on the mode of pulsation of the Mira variables.

The patterns of the ridges of the skin of the fingers and palms were determined in sixty men with complex regional pain syndrome (type I) as a measure of disease prevention. The study included 25 dermatoglyphic traits: number of epidermal ridges on all ten fingers; their sum for five and ten fingers; four traits on both palms, i.e. between a-b, b-c and c-d triradii; atd angles: and their bilateral sum. The data obtained were compared with those recorded in a control group of 200 pairs of imprints of phenotipycally healthy male adults from the Zagreb area. Statistically significant difference from control values were found in 12 dermatoglyphic variables, including an increased sum of ridges on nine fingers (except for left second finger pad), and total sum for five and ten fingers. These findings suggested the polygenic system responsible for development of dermatoglyphics to be identical with some polygenic loci for the onset of algodystrophy syndrome, which might prove useful in disease prevention (e.g., taking fingerprints following a trauma and before rehabilitation), and to facilitate identification of risk groups, and thus the treatment for this longterm and yet obscure syndrome.

Designing an effective hand rotation for plastic surgery residents is difficult. The authors address this limitation by elucidating the critical components of the hand curriculum during plastic surgery residency. Hand questions on the Plastic Surgery In-Service Training Exam for six consecutive years (2008 to 2013) were characterized by presence of imaging, vignette setting, question taxonomy, answer domain, anatomy, and topic. Answer references were quantified by source and year of publication. Two hundred sixty-six questions were related to hand surgery (22.7 percent of all questions; 44.3 per year) and 61 were accompanied by an image (22.9 percent). Vignettes tended to be clinic- (50.0 percent) and emergency room-based (35.3 percent) (p < 0.001). Questions required decision-making (60.5 percent) over interpretation (25.9 percent) and recall skills (13.5 percent) (p < 0.001). Answers focused on interventions (57.5 percent) over anatomy/pathology (25.2 percent) and diagnoses (17.3 percent) (p < 0.001). Nearly half of the questions focused on the digits. The highest yield topics were trauma (35.3 percent), reconstruction (24.4 percent), and aesthetic and functional problems (14.2 percent). The Journal of Hand Surgery (American volume) (20.5 percent) and Plastic and Reconstructive Surgery (18.0 percent) were the most-cited journals, and the median publication lag was 7 years. Green's Operative Hand Surgery was the most-referenced textbook (41.8 percent). These results will enable trainees to study hand surgery topics with greater efficiency. Faculty can use these results to ensure that tested topics are covered during residency training. Thus, a benchmark is established to improve didactic, clinical, and operative experiences in hand surgery.

Low-dose combined oral contraceptives (COCs) can interfere with bone mass acquisition during adolescence. This study aimed to evaluate bone mineral density (BMD) and bone mineral content (BMC) in female adolescents taking a standard low-dose COC (ethinylestradiol 20 μg/desogestrel 150 μg) over a 1-year period and to compare their data with those of healthy adolescents from the same age group not taking COCs. This was a non-randomized parallel-control study with a 1-year follow-up. Sixty-seven adolescents aged from 12 to 19 years, divided into COC users (n = 41) taking 20 μg ethinylestradiol/150 μg desogestrel and COC non-user controls (n = 26), were evaluated by bone densitometry examinations at baseline and after 12 months. Comparisons between the groups at the study onset were performed using the Mann-Whitney test with the significance level fixed at 5% or p variations in the median percentages for bone mass variables. The COC users presented with low bone mass acquisition in the lumbar spine, and had BMD and BMC median variations of 2.07% and +1.57%, respectively, between the measurements at baseline and 12 months. The control group had median variations of +12.16% and +16.84% for BMD and BMC, respectively, over the same period. The total body BMD and BMC showed similar evolutions during the study in both groups. Statistical significance (p variation between COC users and non-users. Use of a low-dose COC (ethinylestradiol 20 μg/desogestrel 150 μg) was associated with lower bone mass acquisition in adolescents during the study period. Registry Number, RBR-5h9b3c.

Embi, Peter J; Desai, Sima; Cooney, Thomas G

2003-01-01

The Internet has become essential to the residency application process. In recent years, applicants and residency programs have used the Internet-based tools of the National Residency Matching Program (NRMP, the Match) and the Electronic Residency Application Service (ERAS) to process and manage application and Match information. In addition, many residency programs have moved their recruitment information from printed brochures to Web sites. Despite this change, little is known about how applicants use residency program Web sites and what constitutes optimal residency Web site content, information that is critical to developing and maintaining such sites. To study the use and perceived utility of Web-based residency program information by surveying applicants to an internal medicine program. Our sample population was the applicants to the Oregon Health & Science University Internal Medicine Residency Program who were invited for an interview. We solicited participation using the group e-mail feature available through the Electronic Residency Application Service Post-Office application. To minimize the possibility for biased responses, the study was confined to the period between submission of National Residency Matching Program rank-order lists and release of Match results. Applicants could respond using an anonymous Web-based form or by reply to the e-mail solicitation. We tabulated responses, calculated percentages for each, and performed a qualitative analysis of comments. Of the 431 potential participants, 218 responded (51%) during the study period. Ninety-nine percent reported comfort browsing the Web; 52% accessed the Web primarily from home. Sixty-nine percent learned about residency Web sites primarily from residency-specific directories while 19% relied on general directories. Eighty percent found these sites helpful when deciding where to apply, 69% when deciding where to interview, and 36% when deciding how to rank order programs for the Match. Forty

Minimum period and the gap in periods of Cataclysmic binaries

International Nuclear Information System (INIS)

Paczynski, B.; Sienkiewicz, R.

1983-01-01

The 81 minute cutoff to the orbital periods of hydrogen-rich cataclysmic binaries is consistent with evolution of those systems being dominated by angular momentum losses due to gravitational radiation. Unfortunately, many uncertainties, mainly poorly known atmospheric opacities below 2000 K, make is physically impossible to verify the quadrupole formula for gravitational radiation by using the observed cutoff at 81 minutes. The upper boundary of the gap in orbital periods observed at about 3 hours is almost certainly due to enhanced angular momentum losses from cataclysmic binaries which have longer periods. The physical mechanism of those losses is not identified, but a possible importance of stellar winds is pointed out. The lower boundary of the gap may be explained with the oldest cataclysmic binaries, whose periods evolved past the minimum at 81 minutes and reached the value of 2 hours within about 12 x 10 9 years after the binary had formed. Those binaries should have secondary components of only 0.02 solar masses, and their periods could be used to estimate ages of the oldest cataclysmic stars, and presumably the age of Galaxy. An alternative explanation for the gap requires that binaries should be detached while crossing the gap. A possible mechanism for this phenomenon is discussed. It requires the secondary components to be about 0.2 solar masses in the binaries just below the gap

Three hundred and four patients with squamous cell carcinomas of the oral cavity were treated at the Finsen Institute in cooperation with the ENT-surgical departments between 1978 and 1982. The primary treatment consisted of radiotherapy alone in 74%, surgery alone in 4%, and a combination of radiotherapy and surgery in 15% of the patients. 2% received other treatment (cryotherapy), 5% did not complete the planned radiotherapy, and 1% were not treated at all. Of 203 patients with tumour remnant or first recurrence, 45% were operated, 2% received radiotherapy, and 2% combined treatment. This treatment strategy made 38% of the patients free of disease in the follow-up period (3 1/2 to 8 years) or until the patients died from other causes. Fifty-nine percent of the patients died from their oral carcinomas. Tumour size (T), lymph node status (N), and tumour stage were as expected important prognostic factors. (orig.).

Super periodic potential

Hasan, Mohammd; Mandal, Bhabani Prasad

2018-04-01

In this paper we introduce the concept of super periodic potential (SPP) of arbitrary order n, n ∈I+, in one dimension. General theory of wave propagation through SPP of order n is presented and the reflection and transmission coefficients are derived in their closed analytical form by transfer matrix formulation. We present scattering features of super periodic rectangular potential and super periodic delta potential as special cases of SPP. It is found that the symmetric self-similarity is the special case of super periodicity. Thus by identifying a symmetric fractal potential as special cases of SPP, one can obtain the tunnelling amplitude for a particle from such fractal potential. By using the formalism of SPP we obtain the close form expression of tunnelling amplitude of a particle for general Cantor and Smith-Volterra-Cantor potentials.

Growing evidence suggests increased HIV incidence in the Middle East and North Africa among "key populations." To date, epidemiological data have not accurately included and measured HIV prevalence and risk among trans feminine individuals in the region. Through the lens of the Gender Affirmation Framework, we assessed demographic correlates of risk behaviour and the prevalence of HIV among trans feminine individuals in Lebanon. Long-chain referral sampling was used to recruit 53 participants for completion of a behavioural survey and optional free rapid HIV tests. Data were collected using interviewer-administered questionnaires. A multivariable logistic regression model was used to identify demographic determinants of HIV risk behaviour. Fifty-seven percent of participants reported condomless receptive anal intercourse (CRAI) with male partner(s) in the last three months, 40% of whom reported not knowing the HIV status of the partner(s). Of the participants tested for HIV as part of the study or via self-report, four (10%) were HIV positive; 13 declined HIV testing. Forty percent of the sample had no prior history of HIV testing. A history of trauma such as sexual abuse/assault was reported by almost half of the participants (49%). Sixty-eight percent reported experiencing physical violence and 32% police arrest, because of gender identity or presentation. A staggering 98% reported having experienced gender identity or gender presentation-related discrimination. Sixty-six percent of the sample reported current sex work; sex work was correlated with CRAI but was not significant in multivariate analysis. In regression analysis, "openness"/"outness" about transgender identity at work or school was significantly associated with CRAI. Surprisingly, a history of sexual abuse/assault was negatively correlated with CRAI, suggesting the need for further inquiry. The results of this study provide implications for how to address sexual health among trans feminine

Appropriate use of administrative data enables the assessment of care quality at the population level. Our objective was to develop/validate methods for assessing quality of breast cancer diagnostic care using administrative data, specifically by identifying relevant medical tests to estimate the percentage screen/symptom-detected cancers and time to diagnosis. Two databases were created for all women diagnosed with a first-ever breast cancer in years 2007-2010 in Alberta, Canada, with dates of medical tests received in years 2006-2010. One purchased database had test results and was used to determine the 'true' first relevant test of a cancer diagnosis. The other free administrative database had test types but no test results. Receiver operating characteristic curves and concordance rates were used to assess estimates of percent screen/symptom-detected breast cancers; Log-rank test was used to assess time to diagnosis obtained from the two databases. Using a look-back period of 4-6 months from cancer diagnosis to identify relevant tests resulted in over 94% concordance, sensitivity and specificity for classifying patients into screen/symptom-detected group; good agreement between the distributions of time to diagnosis was also achieved. Our findings support the use of administrative data to accurately identify relevant tests for assessing the quality of breast cancer diagnostic care. © 2014 John Wiley & Sons Ltd.

Full Text Available We investigate the effect of constant and periodic harvesting on the Beverton-Holt model in a periodically fluctuating environment. We show that in a periodically fluctuating environment, periodic harvesting gives a better maximum sustainable yield compared to constant harvesting. However, if one can also fix the environment, then constant harvesting in a constant environment can be a better option, especially for sufficiently large initial populations. Also, we investigate the combinatorial structure of the periodic sequence of carrying capacities and its effect on the maximum sustainable yield. Finally, we leave some questions worth further investigations.

A feasibility study was conducted for the implementation of the optimum model project in the fiber dyeing and processing industry in Thailand. This paper describes the results of fiscal 1999. Seventy percent of about 400 companies are those heavily consuming energy, while small-scale businesses having a production capacity of less than one million yards/month take the sixty percent of the industry. Their energy conserving measures are behind. Measures against ground subsidence and drainage cost these companies greatly. Trade competition with China and others is being intensified. Although designated under the Energy Saving Promotion Act, the plants are not enjoying the privilege. Needed for the energy saving measures are grasp of the current situation such as energy consumption status, thorough operation management, improvement of energy efficiency in the present production facilities, renewal/additional installation of production equipment, and implementation of developmental energy saving measures. As energy conservation measures are deemed adaptable to the industry if the investment recovery period is two years or less, diagnostic analysis was made on six plants, with diffusion of the result examined. The total energy consumption of the industry was estimated to be reducible by 35% through high-recovery-rate measures such as improvement of boilers, recovery of exhaust heat, control of energy consumption rate, and introduction of dyeing machines having low liquor ratio.

To clinically assess neurogenic dysphagia, and to correlate its presence with demographic features, different stroke risk factors, anatomical arterial territorial stroke types, and pathological stroke types. Seventy-two stroke inpatients were studied between July 2007 and February 2008, at the Departments of Medicine and Neurology at Al-Yarmouk Teaching Hospital, Baghdad, and Rizgary Teaching Hospital, Erbil, Iraq. All patients were assessed using the Mann Assessment of Swallowing Ability score (MASA), Modified Rankin Scale, and the Stroke Risk Scorecard. All patients were reassessed after one month. There were 40 males and 32 females. Sixty-eight patients had ischemic stroke, and 4 had primary intracerebral hemorrhage (ICH). According to the MASA score, 55% of anterior circulation stroke (ACS) cases were associated with dysphasia, and 91% of lateral medullary syndrome cases were associated with dysphagia. Fifty-six percent of ACS dysphagic cases improved within the first month. Forty percent of dysphagic patients died in the one month follow up period, and in most, death was caused by aspiration pneumonia. We observed no significant differences regarding demographic features of dysphagia. Dysphagia can be an indicator of the severity of stroke causing higher mortality and morbidity in affected patients. It was not related to the stroke risk factors and the type of stroke. It is essential from a prognostic point of view to assess swallowing, and to treat its complications early.

Full Text Available Abstract Background Psychosocial support services are an important component of modern cancer treatment. A major challenge for all psychosocial services is the achievement of equity of use. Previous studies in the UK have found that women of higher socio-economic status with breast cancer were over-represented amongst those accessing support services. People with other cancer diagnoses, those from socio-economically deprived areas, and men, were under-represented. Findings The Oncology Health Service, Kingston Upon Hull, UK, delivers fully integrated psychosocial support and interventions. To assess equity of access in this service, a cross-sectional study of all patients with cancer accessing the service during a 5 day period was carried out. One hundred and forty-five patients attended. Forty four percent were male, and the types of cancer were broadly in the proportions expected on the basis of population prevalence (breast cancer 22%, colorectal cancer 21%, lung cancer 16%. Sixty six percent came from the three most deprived quintiles of the Townsend deprivation Index. Conclusions The fully integrated Oncology Health Service in Hull is accessed by a more diverse range of patients than previously reported for other services, and is an example of a model of service by which socially equitable use of psychosocial support in the National Health Service might be achieved.

Rotator cuff tears are a common clinical problem that can result in pain and disability. Previous studies in a rat model showed enhanced tendon to bone healing with postoperative immobilization. The objective of this study was to determine the effect of postimmobilization activity level on insertion site properties and joint mechanics in a rat model. Our hypothesis was that exercise following a short period of immobilization will cause detrimental changes in insertion site properties compared to cage activity following the same period of immobilization, but that passive shoulder mechanics will not be affected. We detached and repaired the supraspinatus tendon of 22 Sprague-Dawley rats, and the injured shoulder was immobilized postoperatively for 2 weeks. Following immobilization, rats were prescribed cage activity or exercise for 12 weeks. Passive shoulder mechanics were determined, and following euthanasia, tendon cross-sectional area and mechanical properties were measured. Exercise following immobilization resulted in significant decreases compared to cage activity in range of motion, tendon stiffness, modulus, percent relaxation, and several parameters from both a structurally based elastic model and a quasi-linear viscoelastic model. Therefore, we conclude that after a short period of immobilization, increased activity is detrimental to both tendon mechanical properties and shoulder joint mechanics, presumably due to increased scar production.

People who stop consuming caffeine may have symptoms, but the incidence and severity of caffeine withdrawal are not known. This study was performed to determine the effects in the general population of ending one's dietary intake of caffeine. We studied 62 normal adults whose intake of caffeine was low to moderate (mean amount, 235 mg--the equivalent of 2.5 cups of coffee--per day). They completed questionnaires about symptoms and tests of their mood and performance when consuming their normal diets (base-line period) and at the end of each of two two-day periods during which they consumed caffeine-free diets and under double-blind conditions received capsules containing placebo (placebo period) or caffeine (caffeine period) in amounts equal to their daily caffeine consumption. More subjects had abnormally high Beck Depression Inventory scores (11 percent), high scores on the trait scale of the State-Trait Anxiety Inventory (8 percent), low vigor scores (11 percent) and high fatigue scores (8 percent) on the Profile of Mood States, and moderate or severe headache (52 percent) during the placebo period than during either the base-line period (2, 0, 0, 0, and 2 percent, respectively; P less than 0.05) or the caffeine period (3, 2, 2, 0, and 6 percent; P less than 0.05). More subjects reported unauthorized use of medications during the placebo period (13 percent) than during the caffeine period (2 percent, P = 0.017). Performance of a tapping task was slower during the placebo period than during the base-line and caffeine periods (P less than 0.01). Persons who consume low or moderate amounts of caffeine may have a withdrawal syndrome after their daily consumption of caffeine ceases.

Full Text Available We show that any mean-periodic function f can be represented in terms of exponential-polynomial solutions of the same convolution equation f satisfies, i.e., u∗f=0(μ∈E′(ℝn. This extends to n-variables the work of L. Schwartz on mean-periodicity and also extends L. Ehrenpreis' work on partial differential equations with constant coefficients to arbitrary convolutors. We also answer a number of open questions about mean-periodic functions of one variable. The basic ingredient is our work on interpolation by entire functions in one and several complex variables.

The purpose of this study was to examine the sensitivity and peak force prediction capability of the interpolated twitch technique (ITT) performed during submaximal and maximal voluntary contractions (MVCs) in subjects with the ability to maximally activate their plantar flexors. Twelve subjects performed two MVCs and nine submaximal contractions with the ITT method to calculate percent voluntary inactivation (%VI). Additionally, two MVCs were performed without the ITT. Polynomial models (linear, quadratic and cubic) were applied to the 10–90% VI and 40–90% VI versus force relationships to predict force. Peak force from the ITT MVC was 6.7% less than peak force from the MVC without the ITT. Fifty-eight percent of the 10–90% VI versus force relationships were best fit with nonlinear models; however, all 40–90% VI versus force relationships were best fit with linear models. Regardless of the polynomial model or the contraction intensities used to predict force, all models underestimated the actual force from 22% to 28%. There was low sensitivity of the ITT method at high contraction intensities and the predicted force from polynomial models significantly underestimated the actual force. Caution is warranted when interpreting the % VI at high contraction intensities and predicted peak force from submaximal contractions

Background: The P hiladelphia Negative Classic Myeloproliferative Neoplasms include polycythaemia vera (PV), essential thrombocythaemia (ET) and idiopathic myelofibrosis (IMF). These three disorders share several clinical and laboratory features including JAK2 V617F mutation. Our objectives were to determine the clinico-pathological profile and outcomes of Pakistani patients with polycythaemia vera (PV), essential thrombocythaemia (ET) and idiopathic myelofibrosis (IMF) in order to have an insight regarding behaviour of these conditions. Methods: A retrospective analysis of all the cases of PV, ET and IMF diagnosed at our institute from January 1995 to December 2013 was performed. Age, gender, clinical presentation, laboratory investigations, treatment provided and duration of follow-up were included for analysis. Appropriate statistics were utilized for calculation of data. Results: A total of 58 patients were diagnosed as PV, ET or IMF during the study period. Male to female ratio was 1.1:1. Forty five percent (n=27) patients came to medical attention due to abnormal laboratory results, 3 had cerebrovascular events, 3 had pruritus, and 1 patient each with gangrene and Budd-Chiari syndrome. Haemorrhage was not seen in any patient. Sixty percent (n=35) patients were treated with phlebotomy, hydroxyurea and aspirin alone or in combination. None of the patients transformed to myelofibrosis (MF) or myelodysplasia (MDS) during the mean (±SD) follow-up period of 57.2±50 months. One patient with ET transformed to acute myeloid leukaemia 9 years after the diagnosis. Conclusions: This study demonstrated a relatively more benign form of PV, ET and IMF with lesser frequency of symptoms, good response to treatment and less likelihood of transformation to MF, MDS or AML.

AIM: To assess the practice of Egyptian physicians in screening patients for hepatocellular carcinoma(HCC). METHODS: The study included 154 physicians from all over Egypt caring for patients at risk for HCC. The study was based on a questionnaire with 20 items. Each questionnaire consisted of two parts:(1) personal information regarding the physician(name, age, specialty and type of health care setting); and(2) professional experience in the care of patients at risk for HCC development(screening, knowledge about the cause and natural course of liver diseases and HCC risk). RESULTS: Sixty-eight percent of doctors with an MD degree, 48% of doctors with a master degree or a diploma and 40% of doctors with a Bachelor of Medicine, Bachelor of Surgery certificate considered the hepatitis C virus(HCV) genotype as risk factor for HCC development(P < 0.05). Ninety percent of physicians specialized in tropical medicine, internal medicine or gastroenterology and 67% of physicians in other specialties advise patients to undergo screening for HCV and hepatitis B virus infection as well as liver cirrhosis(P < 0.05). Eighty-six percent of doctors in University Hospitals and 69% of Ministry of Health(MOH) doctors consider HCV infection as the leading cause of HCC in Egypt(P < 0.05). Seventy-two percent of doctors with an MD degree, 55% of doctors with a master degree or a diploma, 56% of doctors with an MBBCH certificate, 74% of doctors in University Hospitals and 46% of MOH hospital doctors consider abdominal ultrasonography as the most important investigation in HCC screening(P < 0.05). Sixty-five percent of physicians in tropical medicine, internal medicine or gastroenterology and 37% of physicians in other specialties recommend as HCC screening interval of 3 mo(P < 0.05). Seventy-one percent of doctors with an MD degree, 50% of doctors with a master degree or diploma and 60% of doctors with an MBBCH certificate follow the same recommendation.CONCLUSION: In Egypt, physicians

Comparision of alternatively certified and traditionally certified Missouri high school science teachers' perceptions of self-efficacy during the induction period

Science.gov (United States)

Gaither, Linda

Sixty percent of America's teachers choose traditional baccalaureate programs while the remaining choose one of several alternative pathways. While certification/training is certainly important to preparing effective teachers, other research indicates that teacher efficacy serves as the foundation of teacher behaviors and classroom practice. The purpose of this study ( N = 94 induction high school science teachers) was to determine the relationships between certification pathway and opportunities to observe modeling; between years of experience and personal teaching efficacy; and teachers' perceptions of what characteristics/ experiences best explain personal teaching efficacy. The Teacher Sense of Efficacy Scale was used in an on-line survey for Phase 1 (n = 91), to measure teacher self-efficacy. In Phase 2, a basic qualitative study was conducted using telephone interviews ( n = 2) and a focus group (n = 4) along with a series of short essay questions from the online survey (n = 91). The findings indicate a significant relationship (p = 0.01) between years of teaching and overall personal teaching-efficacy, student engagement, and instructional strategies; a relationship between opportunities to see modeling and certification pathway, where traditionally certified teachers had significantly more opportunities (p = 0.000); and a relationship between classroom management and opportunities to see modeling (p = 0.005). Qualitative analyses confirmed that traditionally-prepared teachers saw a range of "modeling" and model teachers; respondents related such opportunities to more effective teaching, especially in the realm of classroom management. As more teachers choose alternative certification, it is imperative that adequate opportunities to observe teaching strategies are modeled during the certification process and once teachers enter the classroom; they must have intrinsic and extrinsic support to be successful.

Exercise levels often decline following cancer diagnosis despite growing evidence of its benefits. Treatment side effects, older age, lack of confidence and opportunity to exercise with others in similar circumstances influence this. Our study explored the experiences of people attending a cancer-specific community-based exercise programme (CU Fitter™). A survey distributed to those attending the programme gathered demographic/clinical information, self-reported exercise levels, information provision and barriers to/benefits of exercise. Sixty surveys were evaluable from 65/100 returned (62% female, 68% > 60 years, 66% breast/prostate cancer). Most (68%) were receiving treatment. Sixty-eight percent attended classes once or twice weekly. Fifty-five percent received exercise advice after diagnosis, usually from their hospital doctor/nurse. More (73%) had read about exercising, but less used the Internet to source information (32%). Self-reported exercise levels were higher currently than before diagnosis (p = 0.05). Forty-eight percent said their primary barrier to exercising was the physical impact of cancer/treatment. Improving fitness/health (40%) and social support (16%) were the most important gains from the programme. Many (67%) had made other lifestyle changes and intented to keep (50%) or increase (30%) exercising. This community-based cancer-specific exercise approach engaged people with cancer and showed physical, psychological, and social benefits. Community-grown exercise initiatives bring cancer survivors together creating their own supportive environment. Combining this with instructors familiar with the population and providing an open-ended service may prove particularly motivating and beneficial. Further work is required to provide evidence for this.

Full Text Available Objectives: The primary objective of the study is to identify the barriers to providing Introductory Pharmacy Practice Experiences (IPPEs in the hospital setting. Methods: Potential barriers to IPPEs were identified via literature review and interviews with current IPPE preceptors from various institutions. Based on this information, an electronic survey was developed and distributed to IPPE preceptors in order to assess student, preceptor, logistical and college or school of pharmacy related barriers that potentially exist for providing IPPE in the hospital setting. Results: Sixty-eight of the 287 eligible survey respondents (24% completed the electronic survey. Seventy-six percent of respondents agreed or strongly agreed that available time was a barrier to precepting IPPE students even though a majority of respondents reported spending a third or more of their day with an IPPE student when on rotation. Seventy-three percent of respondents disagreed or strongly disagreed that all preceptors have consistent performance expectations for students, while just 46% agreed or strongly agreed that they had adequate training to precept IPPEs. Sixty-five percent of respondents agreed that IPPE students have the ability to be a participant in patient care and 70% of preceptors believe that IPPE students should be involved in patient care. Conclusions: Conducting IPPEs in the institutional setting comes with challenges. Based on the results of this study, experiential directors and colleges/schools of pharmacy could make a positive impact on the quality and consistency of IPPEs by setting student expectations and training preceptors on appropriate and consistent expectations for students.   Type: Original Research

Xylazine Exposures Reported to Texas Poison Centers.

Forrester, Mathias B

2016-10-01

Xylazine is a sedative, analgesic, anesthetic, and central muscle relaxant approved for animals but not humans. Although xylazine is an emerging drug of abuse, there are limited data on potentially adverse exposures to the drug. The intent of this study was to describe potentially adverse xylazine exposures reported to a large poison center system. All xylazine exposures reported to Texas poison centers between 2000 and 2014 were included. The distribution of cases by select variables was determined. Of 76 total cases, 93% of the patients were ≥20 years of age, and 54% were male. Fifty-one percent of the exposures occurred by injection, 28% by ingestion, 16% were dermal, 14% were ocular, and 3% by inhalation. Sixty-four percent of the exposures were unintentional, 32% were intentional, and 1% each was related to malicious use and adverse reaction. Sixty-seven percent of the patients were already at or en route to a health care facility when the poison center was contacted, 21% were managed on-site, and 9% were referred to a health care facility. The most common clinical effects were drowsiness or lethargy (47%), bradycardia (20%), hypotension (11%), hypertension (9%), puncture or wound (8%), and slurred speech (8%). Xylazine exposures tended to involve patients who were adult males, exposures were typically unintentional; and most often occurred by injection. Most of the patients were already at or en route to a health care facility when a poison center was contacted. The most frequently reported adverse effects were cardiovascular or neurologic in nature. Copyright © 2016 Elsevier Inc. All rights reserved.

The aim of the 25 by 25 goal is to reduce mortality from premature non-communicable diseases by 25% before 2025. Studies have evaluated the 25 by 25 goal in many countries, but not in Taiwan. The aim of this study was to estimate the 25 by 25 goal for premature mortality from cardiovascular diseases in Taiwan. We applied the age-period-cohort model to project the incidence of premature death from cardiovascular disease from 2015 to 2024 and used the population attributable fraction to estimate the contributions of targeted risk factors. The probability of death was used to estimate the percent change. The percent change in business-as-usual trend during 2010-2024 was only a 6% (range 1.7-10.7%) lower risk of premature mortality from cardiovascular disease among men. The greatest reduction in the risk of mortality occurred with a 30% reduction in the prevalence of smoking; however, there was only a 14.5% (10.6-18.3%) decrease in percent change and in the corresponding number of men (3706: range 3543-3868) who were prevented from dying. More than a 25% reduction in the percent change of premature cardiovascular disease mortality among women was achieved without control of any risk factor. To reach a 25% reduction in men before 2025, there needs to be a 70% reduction in the prevalence of smoking to reduce mortality by 26.2% (22.9-29.3%). Cigarette smoking is the primary target in the prevention of cardiovascular disease. Through the stringent control of smoking, the goal of a 25% reduction in premature mortality from cardiovascular disease may be achieved before 2025 in Taiwan.

The National Water-Quality Assessment (NAWQA) Program of the U.S. Geological Survey (USGS) began implementing Source Water-Quality Assessments (SWQAs) in 2002 that focus on characterizing the quality of source water and finished water of aquifers and major rivers used by some of the larger community water systems in the United States. As used for SWQA studies, source water is the raw (ambient) water collected at the supply well prior to water treatment (for ground water) or the raw (ambient) water collected from the river near the intake (for surface water). Finished water is the water that is treated, which typically involves, in part, the addition of chlorine or other disinfection chemicals to remove pathogens, and is ready to be delivered to consumers. Finished water is collected before the water enters the distribution system. This report describes the study design and percent recoveries of anthropogenic organic compounds (AOCs) with and without the addition of ascorbic acid to preserve water samples containing free chlorine. The percent recoveries were determined by using analytical results from a laboratory study conducted in 2004 by the USGS's National Water Quality Laboratory (NWQL) and from data collected during 2004-06 for a field study currently (2008) being conducted by the USGS's NAWQA Program. The laboratory study was designed to determine if preserving samples with ascorbic acid (quenching samples) adversely affects analytical performance under controlled conditions. During the laboratory study, eight samples of reagent water were spiked for each of five analytical schedules evaluated. Percent recoveries from these samples were then compared in two ways: (1) four quenched reagent spiked samples analyzed on day 0 were compared with four quenched reagent spiked samples analyzed on day 7 or 14, and (2) the combined eight quenched reagent spiked samples analyzed on day 0, 7, or 14 were compared with eight laboratory reagent spikes (LRSs).

The aim of this study was to evaluate the effect of daily consumption and/or application of argan oil on skin hydration in postmenopausal women. Sixty postmenopausal women consumed butter during the stabilization period and were randomly divided into two groups for the intervention period: the treatment group absorbed alimentary argan oil (n = 30) and the control group olive oil (n = 30). Both groups applied cosmetic argan oil in the left volar forearm during a sixty days' period. Evaluation of skin hydration, i.e. transepidermal water loss (TEWL) and water content of the epidermis (WCE) on both volar forearms of the two groups, were performed during three visits at D0, D30 and after sixty days (D60) of oils treatment. The consumption of argan oil has led to a significant decrease in TEWL (p = 0.023) and a significant increase in WCE (p = 0.001). The application of argan oil has led to a significant decrease in TEWL (p = 0.01) and a significant increase in WCE (p skin hydration by restoring the barrier function and maintaining the water-holding capacity.

Sixty-Seven Years of Land-Use Change in Southern Costa Rica.

Habitat loss and fragmentation of forests are among the biggest threats to biodiversity and associated ecosystem services in tropical landscapes. We use the vicinity of the Las Cruces Biological Station in southern Costa Rica as a regional case study to document seven decades of land-use change in one of the most intensively studied sites in the Neotropics. Though the premontane wet forest was largely intact in 1947, a wave of immigration in 1952 initiated rapid changes over a short period. Overall forest cover was reduced during each time interval analyzed (1947-1960, 1960-1980, 1980-1997, 1997-2014), although the vast majority of forest loss (>90%) occurred during the first two time intervals (1947-1960, 1960-1980) with an annual deforestation rate of 2.14% and 3.86%, respectively. The rate dropped to forest recovery in fallow areas more recently, but overall forest cover has continued to decline. Approximately 27.9% of the study area is forested currently. Concomitantly, the region shifted from a single contiguous forest to a series of progressively smaller forest fragments with each successive survey. A strong reduction in the amount of core habitat was paralleled by an increased proportion of edge habitat, due to the irregular shape of many forest fragments. Structural connectivity, however, remains high, with an expansive network of >100 km of linear strips of vegetation within a 3 km radius of the station, which may facilitate landscape-level movement for some species. Despite the extent of forest loss, a substantial number of regional landscape-level studies over the past two decades have demonstrated the persistence of many groups of organisms such as birds and mammals. Nonetheless, the continued decline in the quantity and quality of remaining habitat (~30% of remaining forest is secondary), as well as the threat of an extinction debt (or time lag in species loss), may result in the extirpation of additional species if more proactive conservation measures

Triple antithrombotic therapy increases the risk of bleeding events in patients undergoing percutaneous coronary intervention. However, it remains unclear whether good control of percent time in therapeutic range is associated with reduced occurrence of bleeding complications in patients undergoing triple antithrombotic therapy. This study included 2648 patients (70 ± 11 years; 2037 men) who underwent percutaneous coronary intervention with stent in the Ibaraki Cardiovascular Assessment Study registry and received dual antiplatelet therapy with or without warfarin. Clinical end points were defined as the occurrence of major bleeding complications (MBC), major adverse cardiac and cerebrovascular event, and all-cause death. Among these 2648 patients, 182 (7%) patients received warfarin. After a median follow-up period of 25 months (interquartile range, 15-35 months), MBC had occurred in 48 (2%) patients, major adverse cardiac and cerebrovascular event in 484 (18%) patients, and all-cause death in 206 (8%) patients. Multivariable Cox regression analysis revealed that triple antithrombotic therapy was the independent predictor for the occurrence of MBC (hazard ratio, 7.25; 95% confidence interval, 3.05-17.21; Prange value did not differ between the patients with and without MBC occurrence (83% [interquartile range, 50%-90%] versus 75% [interquartile range, 58%-87%]; P=0.7). However, the mean international normalized ratio of prothrombin time at the time of MBC occurrence was 3.3 ± 2.1. Triple antithrombotic therapy did not have a predictive value for the occurrence of all-cause death (P=0.1) and stroke (P=0.2). Triple antithrombotic therapy predisposes patients to an increased risk of MBC regardless of the time in therapeutic range.
