    Full Text Available The aim of this study was to present the epidemiological, clinical and microbiological data, as well as the management and the outcome of 13 patients with documented Pasteurella multocida infections, diagnosed in the University hospital of Crete, Greece, between 1993 and 2004. Most patients (62% were >70 years of age. Respiratory tract infections were most commonly encountered (61.5%, followed by soft-tissue infections (30.8% and septicemia (7.7 %. Underlying diseases included malignancies, bullous pemphigoid, mitral valve stenosis, coronary disease, chronic obstructive pulmonary disease and intracranial hemorrhage. Antibiotic sensitivity testing showed that all P. multocida isolates were susceptible to beta-lactams, quinolones, chloramphenicol, tetracycline and trimethoprim/sulfamethoxazole. Antibiotics were administered to all 13 patients and a clinical response was observed in 77% of them. The overall mortality rate was 23% (3/13 but only 15.4% (2/13 died from the infection. Although rare, P. multocida infections should be suspected in patients reporting animal exposure, particularly in those with chronic underlying diseases.

    The nutritional status of under-five-year-old children is a sensitive indicator of a country's health status as well as economic condition. The objectives of this study were to analyse trends in the nutritional status in Bangladeshi children over the period 1996-2007 and to examine the associations between nutritional and socioeconomic status variables. Bangladesh Demographic Health Surveys (BDHS) were the source of data, and a total of 16,278 children were examined. The Z-scores of the children were analysed as continuous as well as categorical variables (stunted, underweight and wasted). The socioeconomic status variables used were region, urban-rural residence, education and occupation of the parents, house type and household possession score. A series of General Linear Model and Sequential Linear and Binary Logistic Regression analyses were done to assess the relationship between demographic and socioeconomic variables and nutritional status. The trends of Z-scores were analysed by survey, as well as by child birth cohort. Region, house type, educational level of parents and household possession score showed significant associations with all three Z-scores of children after removing the effects of age, period of DHS and other explanatory variables in the model. No significant sex difference was observed between any of the Z-scores. There were improvements in mean WAZ and HAZ between 1996 and 2007 but deterioration in mean WHZ over this period. The obesity rate was below 2% in 2007, although the absolute numbers of obese children had nearly doubled in this 12-year period. Children from poorer households showed greater improvement than their better-off counterparts. The study reveals that over the years there has been substantial improvement in nutritional status of under-five children in Bangladesh and the main gains have been amongst the lower socioeconomic groups; it is also evident that malnutrition in Bangladesh is a multidimensional problem, like poverty

    The Brazzaville cancer registry was created in 1996 with the support of the International Agency Research against Cancer (IARC) which is located in Lyon, France. The Brazzaville cancer registry is a registry which is based on population which records new cancer cases occurring in Brazzaville by using Canreg 4.0 Software. Its aim is to supply useful information to fight against cancer to physicians and to decision makers. We conducted this study whose target was to determine the incidence of cancer in Brazzaville during twelve years, from January 1st, 1998 to December 31, 2009. During that period 6,048 new cancer cases were recorded: 3,377 women (55.8%), 2,384 men (39.4%), and 287 children (4.8%) from 0 to 14 years old with an annual average of 504 cases. Middle age to the patient's diagnosis was 49.5 years in female sex and 505.5 years old for male sex. The incidence rate of cancers in Brazzaville was 39.8 or 100.000 inhabitants per year and by sex we observed 49 to female sex and 35.2 for male sex. The first cancers localizations observed to women were in order of frequency: breast, cervix uterine, liver ovaries, hematopoietic system, to men : liver, prostate, hematopoietic system, colon and stomach; to children : retina, kidney, hematopoietic system, liver and bones. These rates are the basis to know the burden of cancer among all pathologies of Brazzaville and the achievement of a national cancer control program.

    Pelvic organ prolapse is a common morbidity among Bangladeshi women. Both patient and surgeon prefer vaginal hysterectomy for the treatment of this condition and occasionally they choose Fothergill's operation. Uterine suspension is suitable for the young women to preserve the uterus. This observational study was carried out in three teaching hospitals and two other non government hospitals for the period of 12 years among 280 patients with 1st, 2nd and 3rd degree uterine prolapse. Follow up done at 6th week , 6th month, 1st year, 5th year, 10th year and 12th year for recurrence of prolapse, dragging pain and dyspareunia. Among 280 patients >60% patients were of 26-30 years age group. In last follow up at 12th year 2(0.71%) women complained feeling of some descend of uterus, 1(0.36%) complained dragging pain in abdomen and I (0.36%) complained dyspareunia. All patients expressed satisfaction which indicates psychological well being. Uterine sling is an effective procedure to save uterus in young women to improve their quality of life.

    Full Text Available Perhaps no innovation in history has affected marketing management as pervasively as has the advent of e-commerce. This revolutionary new channel has required businesses to acquire an entirely new set of skills and approaches to promotion, pricing, and distribution. The necessity for e-commerce website operators to more deeply understand consumer behavior when engaged in e-commerce has become a central and crucial factor in website success or failure. As predicted nearly 20 years ago, travel bookings have moved almost entirely to the World Wide Web (WWW. For the past 12 years, data have been collected concerning traveler’s preferences, concerns, and perceptions of airline websites in particular. This research reviews and comments on the evolution of those sites and consumer perceptions of efficiency, ease of use, and usefulness. The results of this study are intended to guide airlines in their pursuit of customer satisfaction and increased profits.

    Mexico is the second country in Latin America with regard to Nanoscience and Nanotechnology Research and Development, according to various indicators. Nanoscience and Nanotechnologies are viewed as strategic areas in government policy since 2001. In the last few decades, important policy changes in Science and Technology (S&T) have been implemented with an aim to integrate the business sector with government scientific research. This article reviews information from the Web of Science relevant to articles on nanoscience and nanotechnology stretching back 12 years, and explains the changes in S&T policy. The information uncovered leads to three conclusions: the participation of the business sector is negligible; there is a significant concentration of scientific production among a very few institutions; and the country is essentially divided geographically, with scientific production concentrated in the center and north of the country.

  10. Twelve years of cooperation in the field of radiation protection

    SSI has pursued an international cooperation program since 1992 within the field of radiation protection and emergency preparedness for radiation accidents with the three Baltic countries as main beneficiaries. As the Baltic countries are members of the EU since May 2004, this bilateral support will now be phased out and replaced with other forms of cooperation. During the years passed, a large number of activities have been launched with a total budget of some 14 million ECU. The Baltic radiation protection authorities have played a big role in the cooperation and Baltic ministries, universities, nuclear technology installations and other industries using radiation have also been engaged in the projects. SKI, SKB, Studsvik and the Swedish nuclear power plants should be mentioned as major cooperation partners on the Swedish side. During autumn 2004 when such a large coordinated work program was coming to an end, SSI decided to hold a seminar with the purpose to follow up experiences from the work and discuss coming forms of cooperation. The seminar took place on the 18 of November 2004 and gathered some 80 participants, 29 of which from the Baltic countries. It was opened by Lars-Erik Holm, the SSI Director General, and the three Baltic countries then presented their views and impressions from the passed years of cooperation. The seminar was concluded with a panel discussion on 'How to proceed from today's situation'. The result was that SSI invited to a new coordination meeting during autumn 2005 to follow up and discuss coordination of radiation protection around the Baltic Sea together with the other Nordic radiation protection authorities.

    Human milk is a rich source of bioactive proteins that support the early growth and development of the newborn. Although the major components of the protein fraction in human milk have been studied, the expression and relative abundance of minor components have received limited attention. We examined the expression of low-abundance proteins in the whey fraction of human milk and their dynamic changes over a twelve-month lactation period. The low-abundance proteins were enriched by ProteoMiner beads, and protein identification was performed by liquid chromatography tandem mass spectrometry. One hundred and fifteen proteins were identified, thirty-eight of which have not been previously reported in human colostrum or milk. We also for the first time described differences in protein patterns among the low-abundance proteins during lactation. These results enhance our knowledge about the complexity of the human milk proteome, which constitutes part of the advantages to the breast-fed infant.

  12. Twelve-year cyclic surging episode at Donjek Glacier in Yukon, Canada

    Surge-type glaciers exhibit several-fold to orders-of-magnitude speed-up during the short active phase, resulting in km-scale terminus advance. Although there are many surge-type glaciers near the border of Alaska and the Yukon, the generation mechanisms remain uncertain because of limited and few continuous observations. To better understand the surge dynamics and predict the next event, it is essential to examine the entire surge cycles. Here we use Landsat optical imageries to reveal the long-term evolutions, and report three surging episodes at Donjek Glacier in Yukon, Canada. Using the Landsat images, we found three surging events in 1989, 2001, and 2013. In the 2001 event, the surface speed significantly increased by up to 4.5 m/d; during the quiescent phases it was ~0.5 m/d at the terminus. While the duration of active phase is about 4~5 and 2~3 year in the 2001 and 2013 events, the period in the 1989 event is unclear because of the lack of high temporal resolution data. Remarkably, the surging area is limited to the ~20-km section from the terminus instead of the entire glacier. Moreover, we examined the terminus area changes from 1975 to 2014. Although the area has been secularly decreasing probably due to the tread of global warming, it has also revealed four significant fluctuations during the nearly forty years. Comparing the speed and the area changes, the three speed-up events correspond to the terminus area fluctuations with a few time lags. It turns out that the surge event has been quite regularly repeating every twelve years. Although the behavior is rather similar to that in Svalbard glaciers in terms of maximum speed and unclear initiation season, the recurrence interval is much shorter than other nearby surges. Considering that the surge events seem to have initiated around significantly narrower area than upstream, the strong valley constriction may control the regularity as well as the twelve-year recurrence time.

    2016-01-01

    Full Text Available China has been experiencing severe air pollution and previous studies have mostly focused on megacities and a few hot spot regions. Hefei, the provincial capital city of Anhui province, has a population of near 5 million in its metropolitan area, but its air quality has not been reported in literature. In this study, daily PM10 and visibility data in 2001–2012 were analyzed to investigate the air quality status as well as the twelve-year pollution trends in Hefei. The results reveal that Hefei has been suffering high PM10 pollution and low visibility during the study period. The annual average PM10 concentrations are 2~3 times of the Chinese Ambient Air Quality Standard. PM10 shows fluctuating variation in 2001–2007 and has a slightly decreasing trend after 2008. The annual average visibility range is generally lower than 7 km and shows a worsening trend from 2001 to 2006 followed by an improving trend from 2007 to 2012. Wind speed, precipitation, and relative humidity have negative effects on PM10 concentrations in Hefei, while temperature could positively or negatively affect PM10. The results provide a general understanding of the status and long-term trends of PM10 pollution and visibility in a typical second-tier city in China.

    PFAPA is a periodic fever syndrome characterized by: fever, aphthous stomatitis, pharyngitis and cervical adenitis. It is one of the autoinflammatory syndromes, but yet of unknown etiology. Our aim is to report our experience, describe clinical manifestations, laboratory findings, relapses occurrence and response to treatment. We present 12 PFAPA patients. Median age at onset: 1.15 years, mean duration of febrile episodes: 4 days, and relapses at regular intervals. All children received prednisone (1-2 mg/kg/dose) one to two doses, 9 patients responded immediately after the first dose and all experienced a lower periodicity of attacks. PFAPA is the most frequent periodic fever syndrome. To our knowledge, there are no other local series of PFAPA patients published. Recognizing this syndrome will prevent from ordering unnecessary studies and will favor family coping.

    Global surface temperature change is one of the most important aspects in global climate change research. In this study, in order to overcome shortcomings of traditional observation methods in meteorology, a new method is proposed to calculate global mean surface temperature based on remote sensing data. We found that (1) the global mean surface temperature was close to 14.35 °C from 2001 to 2012, and the warmest and coldest surface temperatures of the global in the recent twelve years occurred in 2005 and 2008, respectively; (2) the warmest and coldest surface temperatures on the global land surface occurred in 2005 and 2001, respectively, and on the global ocean surface in 2010 and 2008, respectively; and (3) in recent twelve years, although most regions (especially the Southern Hemisphere) are warming, global warming is yet controversial because it is cooling in the central and eastern regions of Pacific Ocean, northern regions of the Atlantic Ocean, northern regions of China, Mongolia, southern regions of Russia, western regions of Canada and America, the eastern and northern regions of Australia, and the southern tip of Africa. The analysis of daily and seasonal temperature change indicates that the temperature change is mainly caused by the variation of orbit of celestial body. A big data model based on orbit position and gravitational-magmatic change of celestial body with the solar or the galactic system should be built and taken into account for climate and ecosystems change at a large spatial-temporal scale.

    Full Text Available The aim of the study was to explore the patterns of dental health services access in children under twelve years of age in Peru. Data from 25,285 children under 12 years who participated in the Demographic and Family Health Survey of 2014 were reviewed. An exploratory spatial analysis was performed to project the proportions of children with access to dental health services, according to national regions, type of health service and urban or rural place of residence. The results show that of the total sample, 26.7% had access to dental health services in the last six months, 39.6% belonged to the age group 0-4 years, 40.6% lived in the Andean region and 58.3% lived in urban areas. The regions of Huancavelica, Apurimac, Ayacucho, Lima and Pasco had the highest percentages of access nationwide. In conclusion, there is low access to dental health services in the population under 12 years of age in Peru. The spatial distribution of access to dental health services allows regions to be identified and grouped according to similar access patterns, in order to better focus public health actions.

    The evolution of knowledge and technology in recent decades has brought profound changes in science policy, not only in the countries but also in the supranational organizations. It has been necessary, therefore, to adapt the scientific institutions to new models in order to achieve a greater and better communication between them and the political counterparts responsible for defining the general framework of relations between science and society. The Federationon of Scientific Societies of Spain (COSCE, Confederación de Sociedades Científicas de España) was founded in October 2003 to respond to the urgent need to interact with the political institutions and foster a better orientation in the process of making decisions about the science policy. Currently COSCE consists of over 70 Spanish scientific societies and more than 40,000 scientists. During its twelve years of active life, COSCE has developed an intense work of awareness of the real situation of science in Spain by launching several initiatives (some of which have joined other organizations) or by joining initiatives proposed from other groups related to science both at the Spanish level and at the European and non-European scenarios.

    2007-08-01

    Full Text Available Background: People vary greatly in their response to painful stimuli, from those with a low pain threshold to those with indifference to pain. However, insensitivity to pain is a rare disorder, characterized by the lack of usual subjective and objective responses to noxious stimuli. Patients who have congenital indifference to pain sustain painless injuries beginning in infancy, but have sensory responses that are otherwise normal on examination. Perception of passive movement, joint position, and vibration is normal in these patients, as are tactile thresholds and light touch perception. Case report: A twelve-year-old boy was admitted to the hospital for a painless deformity, degeneration in both knees and a neglected femoral neck fracture that was inappropriately painless. Further examination revealed normal sensory responses, perception of passive movement, joint position, vibration tactile thresholds and light touch perception. Spinal cord and brain MRI were normal as was the electromyography and nerve conduction velocity (EMG/NCV examination. There was no positive family history for this disorder. Conclusion: The deficits present in the different pain insensitivity syndromes provide insight into the complex anatomical and physiological nature of pain perception. Reports on pain asymbolia, in which pain is perceived but does not cause suffering, and related cortical conditions illustrate that there can be losses that independently involve either the sensory-discriminative component or the affective-motivational component of pain perception, thus highlighting their different anatomical localization. The paucity of experience with this entity and the resultant diagnostic problems, the severity of the associated disabling arthropathy and underscore the importance of this case report of indifference to pain.

  4. Twelve-year trail of clues leads to impact crater from the K-T boundary

    Energy Technology Data Exchange (ETDEWEB)

    Levi, B.G.

    1992-12-01

    In 1980, scientists at the University of California, Berkeley proposed that a massive comet or asteroid might have struck the earth about 65 million years ago, changing the earth's climate so drastically that dinosaurs and other creatures could no longer survive. This article describes the evidence for the elusive crater required to support this theory. The structure in question is 180 km in diameter and is submeged beneath the Yucatan peninsula and centered on the Mexican village of Chicxulub. Material drilled from this crater has been linked chemically and geologically to pellets found in Northeast Mexico and Haiti. The link between this ejecta material and the crater was confirmed by a report that the Chicxulub melt rock and pellets are coeval, all having ages consistent with 65 million years. This puts the possible impact at the K-T boundary -- the dividing line between the Cretaceous period of the dinosaurs and the Tertiary period of the mammals. 13 refs.

    Full Text Available Abstract Background Despite the growing availability of clinical practice guidelines since the early 1990's, little is known about how guideline development and dissemination may have changed over time in Canada. This study compares Canadian guideline development, dissemination, and evaluation in two six year periods from 1994–1999 and 2000–2005. Methods Survey of guideline developers who submitted their clinical practice guidelines to the Canadian Medical Association Infobase (a Canadian guideline repository between 1994 and 2005. Survey items included information about the developers, aspects of guideline development, and dissemination and evaluation activities. Results Surveys were sent to the developers of 2341 guidelines in the CMA Infobase over the 12 year period, 1664 surveys were returned (response rate 71%. Of these, 730 unique guidelines were released from 1994–1999, and 630 were released from 2000–2005. Compared to the earlier period, more recent guidelines were being produced in English only. There has been little change in the type of organizations developing guidelines with most developed by provincial and national organizations. In the recent period, developers were more likely to report using computerized search strategies (94% versus 88%, publishing the search strategy (42% versus 34%, reaching consensus using open discussion (95% versus 78%, and evaluating effectiveness of the dissemination strategies (12% versus 6% and the impact of the CPGs on health outcomes (24% versus 5%. Recent guidelines were less likely to be based on literature reviews (94% versus 99.6% and were disseminated using fewer strategies (mean 4.78 versus 4.12. Conclusion Given that guideline development processes have improved in some areas over the past 12 years yet not in others, ongoing monitoring of guideline quality is required. Guidelines produced more recently in Canada are less likely to be based on a review of the evidence and only about

    This study presents the results in 66 patients undergoing surgery for concomitant supracoronary vascular interposition and valve replacement carried out at the Department of Cardiac Surgery of the University of Munich, West-Germany, over a period of 12 years (from July 1, 1973 to June 30, 1985) using a technique similar to that described by Wheat. Forty-seven percent of the cases were true aneurysms and 20% chronic dissections. Thirty-three percent of patients had acute dissections. Early mortality was 16% in the total patient population, 9% in the group having true aneurysm and 32% in the group having acute dissection. No early death was observed in association with chronic dissections. The actuarial one-year survival rate in patients with true aneurysm or chronic dissection was 83.6%, and 54.1% in patients with acute dissection. The corresponding 4-year survival rates were 76.4% and 54.1%, respectively. The average improvement according to the New York Heart Association classification was 1.5 grades. These results confirm that the operative approach to ascending aortic aneurysms is superior to medical treatment, with the operative method involving vascular graft without concomitant aortic valve replacement as well as the method described by Wheat having both proved successful.

    Full Text Available BACKGROUND: Despite the small contribution of LA in the Science Citation Index (SCI, a growing contribution by LA research to international literature has been observed in recent years. STUDY DESIGN: Systematic review. PURPOSE: To evaluate the scientific contribution of Latin American (LA Spine Surgeons in the last decade. METHODS: A literature search of publications by LA spinal surgeons on topics concerning the spine or spinal cord was performed using an online database; Pubmed.gov. The results were limited to articles published from January 2000 to December 2011. The quality of the publication was evaluated with the journal impact factor (IF, Oxford classification and number of citations. RESULTS: This study comprised 320 articles published in the Medline database by LA spine surgeons from 2000 to 2011. In recent years, there has been an increase in the number of publications by LA spine surgeons. It was observed that 38.4% of LA papers were published in LA journals. 46.6% of the articles were published in journals with an IF lower than 1, and there was no statistically significant difference in the number of articles published in journals with a higher IF during the period. Linear-by-linear association analysis demonstrated an improvement in the level of evidence provided by LA articles published in recent years. CONCLUSIONS: This study showed a growth in the number of publications in last 12 years by LA spinal surgeons. It is necessary to discuss a way to increase quantity and quality of scientific publications, mainly through a better education in research.

    Understanding stream carbon export dynamics is needed to accurately predict how the carbon balance of peatland catchments will respond to climatic and environmental change. We used a 12 year record (2003-2014) of continuous streamflow and manual spot measurements of total organic carbon (TOC), dissolved inorganic carbon (DIC), methane (CH4), and organic carbon quality (carbon-specific ultraviolet absorbance at 254 nm per dissolved organic carbon) to assess interannual and seasonal variability in stream carbon export for a peatland catchment (70% mire and 30% forest cover) in northern Sweden. Mean annual total carbon export for the 12 year period was 12.2 gCm-2 yr-1, but individual years ranged between 6 and 18 gCm-2 yr-1. TOC, which was primarily composed of dissolved organic carbon (>99%), was the dominant form of carbon being exported, comprising 63% to 79% of total annual exports, and DIC contributed between 19% and 33%. CH4 made up less than 5% of total export. When compared to previously published annual net ecosystem exchange (NEE) for the studied peatland system, stream carbon export typically accounted for 12 to 50% of NEE for most years. However, in 2006 stream carbon export accounted for 63 to 90% (estimated uncertainty range) of NEE due to a dry summer which suppressed NEE, followed by a wet autumn that resulted in considerable stream export. Runoff exerted a primary control on stream carbon export from this catchment; however, our findings suggest that seasonal variations in biologic and hydrologic processes responsible for production and transport of carbon within the peatland were secondary influences on stream carbon export. Consideration of these seasonal dynamics is needed when predicting stream carbon export response to environmental change.

  9. Twelve thousand years of dust: the Holocene global dust cycle constrained by natural archives

    Full Text Available Mineral dust plays an important role in the climate system by interacting with radiation, clouds, and biogeochemical cycles. In addition, natural archives show that the dust cycle experienced variability in the past in response to global and local climate change. The compilation of the DIRTMAP paleodust datasets in the last two decades provided a target for paleoclimate models that include the dust cycle, following a time slice approach. We propose an innovative framework to organize a paleodust dataset that moves on from the positive experience of DIRTMAP and takes into account new scientific challenges, by providing a concise and accessible dataset of temporally resolved records of dust mass accumulation rates and particle grain-size distributions. We consider data from ice cores, marine sediments, loess/paleosol sequences, lake sediments, and peat bogs for this compilation, with a temporal focus on the Holocene period. This global compilation allows investigation of the potential, uncertainties and confidence level of dust mass accumulation rates reconstructions, and highlights the importance of dust particle size information for accurate and quantitative reconstructions of the dust cycle. After applying criteria that help to establish that the data considered represent changes in dust deposition, 43 paleodust records have been identified, with the highest density of dust deposition data occurring in the North Atlantic region. Although the temporal evolution of dust in the North Atlantic appears consistent across several cores and suggest that minimum dust fluxes are likely observed during the Early to mid-Holocene period (6000–8000 years ago, the magnitude of dust fluxes in these observations is not fully consistent, suggesting that more work needs to be done to synthesize datasets for the Holocene. Based on the data compilation, we used the Community Earth System Model to estimate the mass balance and variability of the global dust cycle

    2005-01-01

    The Brazilian External Quality Assessment Program in Immunohematology (BEQAPI) was introduced with the objective of evaluating the quality of diagnosis in immunohematology. From 1992 to 2003, proficiency tests for ABO grouping, Rh (D, C, c, E, e), K phenotyping, direct antiglobulin testing (DAT), antibody screening (AS), and antibody identification (AI) were performed. A total of 41 evaluations were carried out in 223 institutions. Over the period of 12 years, the program included 8,014 ABO typing, 8,000 RhD typing, 5,193 Rh typing (C, c, E, e), 5,101 K phenotyping, 7,939 AS, 4,533 AI, and 7,912 DATs. Erroneous responses were classified as clerical, technical, or undetermined. A substantial proportion of erroneous responses due to clerical errors occurred in ABO typing (76/76 errors), RhD typing (34/58 errors), and Rh phenotyping (50/73 errors). Technical errors occurred predominantly for weak D (91/95 errors), AS (252/301 errors), and AI (321/335 errors). Based on these results, since 1996, participants have received "Questions and Case Studies" in Immunohematology as an incentive for training and education. The results of the present study show an improvement in the performance of participants in the course of the program. We found that a well-organized external proficiency program can contribute to the improvement of quality of testing in Immunohematology.

    The Crew Earth Observations (CEO) payload was one of the initial experiments aboard the International Space Station, and has been continuously collecting data about the Earth since Expedition 1. The design of the experiment is simple: using state-of-the-art camera equipment, astronauts collect imagery of the Earth's surface over defined regions of scientific interest and also document dynamic events such as storms systems, floods, wild fires and volcanic eruptions. To date, CEO has provided roughly 600,000 images of Earth, capturing views of features and processes on land, the oceans, and the atmosphere. CEO data are less rigorously constrained than other remote sensing data, but the volume of data, and the unique attributes of the imagery provide a rich and understandable view of the Earth that is difficult to achieve from the classic remote sensing platforms. In addition, the length-of-record of the imagery dataset, especially when combined with astronaut photography from other NASA and Russian missions starting in the early 1960s, provides a valuable record of changes on the surface of the Earth over 50 years. This time period coincides with the rapid growth of human settlements and human infrastructure.

    Introduction The objective of this study was to analyze the content and volume of literature that has been written on cultural competency in emergency medicine (EM) since its educational imperative was first described by the Institute of Medicine in 2002. Methods We conducted a comprehensive literature search through the PubMed portal in January 2015 to identify all articles and reviews that addressed cultural competency in EM. Articles were included in the review if cultural competency was described or if its impact on healthcare disparities or curriculum development was described. Two reviewers independently investigated all relevant articles. These articles were then summarized. Results Of the 73 abstracts identified in the initial search, only 10 met criteria for inclusion. A common theme found among these 10 articles is that cultural competency in EM is essential to reducing healthcare disparities and improving patient care. These articles were consistent in their support for cross-cultural educational advancements in the EM curriculum. Conclusion Despite the documented importance of cultural competency education in medicine, there appears to be only 10 articles over the past 12 years regarding its development and implementation in EM. This comprehensive literature review underscores the relative dearth of publications related to cultural competency in EM. The limited number of articles found is striking when compared to the growth of EM research over the same time period and can serve as a stimulus for further research in this significant area of EM education.

    We analyzed the characteristics associated with the growth in weight of Japanese triplets from birth to 12 years of age. The study included 376 mothers and their 1,128 triplet children, who were born between 1978 and 2006. Data were collected through a mailed questionnaire sent to the mothers asking for information recorded in medical records. For these births, data on triplets' weight growth, gestational age, sex, parity, maternal age at delivery, maternal height, and maternal body mass index were obtained from records in the Maternal and Child Health Handbooks and records in the school where children receive health check-ups. The weight deficit of the triplets compared to the general population of Japan remained between 10% and 17% until 12 years of age. Moreover, at 12 years of age, the differences of weight between the general population and triplets were approximately -4.75 kg for boys and -6.00 kg for girls. Very low birth weight had the strongest contribution to body weight until 8 years of age. After 8 years of age, maternal body mass index was a significant factor affecting the weight of triplets until 12 years of age.

We report the case of a 61-year-old woman presenting with bowel obstruction, related to metastasis of a primary breast cancer she had 12 years earlier (a triple-negative invasive ductal carcinoma treated with surgery and chemotherapy. Bowel obstruction was caused by a 20-centimeter tumor in the jejunum, involving also the transverse colon. The patient underwent en bloc resection of tumor with jejunum and transverse bowel segment and received adjuvant chemotherapy with carboplatin and paclitaxel. Twenty months later, she was alive without disease recurrence.

    recordings and landslides occurred) and to use them to define more robust relationships between rainfalls and landslide triggering, with the final aim to increase the forecasting effectiveness of the warning system. The updated rainfall and landslide database were used to periodically perform a quantitative validation and to analyze the errors affecting the system forecasts. The errors characterization was used to implement a continuous process of updating and modification of SIGMA, that included: - Main model upgrades (generalization from a pilot test site to the whole Emilia Romagna region; calibration against well documented landslide events to define specific σ levels for each territorial units; definition of different alert levels according to the number of expected - Ordinary updates (periodically, the new landslide and rainfall data were used to re-calibrate the thresholds, taking into account a more robust sample). - Model tuning (set up of the optimal version of the decisional algorithm, including different definitions of "long" and "short" periods; selection of the optimal reference rain gauge for each Territorial Unit; modification of the boundaries of some territorial - Additional features (definition of a module that takes into account the effect of snow melt and snow accumulation; coupling with a landslide susceptibility model to improve the spatial accuracy of the model). - Various performance tests (including the comparison with alternate versions of SIGMA or with thresholds based on rainfall intensity and duration). This process has led to an evolution of the warning system and to a documented improvement of its forecasting effectiveness. Landslide forecasting at regional scale is a very complex task, but as time passes by and with the systematic gathering of new substantial data and the continuous progresses of research, uncertainties can be progressively reduced and a warning system can be set that increases its performances and reliability with time.

  1. Twelve years of global observation of formaldehyde in the troposphere using GOME and SCIAMACHY sensors

    Directory of Open Access Journals (Sweden)

    I. De Smedt

    2008-04-01

    Full Text Available This work presents global tropospheric formaldehyde columns retrieved from near-UV radiance measurements performed by the GOME instrument onboard ERS-2 since 1995, and by SCIAMACHY, in operation on ENVISAT since the end of 2002. A special effort has been made to ensure the coherence and quality of the CH2O dataset covering the period 1996–2007. Optimised DOAS settings are proposed in order to reduce the impact of two important sources of error in the derivation of slant columns, namely, the polarisation anomaly affecting the SCIAMACHY spectra around 350 nm, and a major absorption band of the O4 collision complex centred near 360 nm. The air mass factors are determined from scattering weights generated using radiative transfer calculation taking into account the cloud fraction, the cloud height and the ground albedo. Vertical profile shapes of CH2O are provided by the global CTM IMAGES based on an up-to-date representation of emissions, atmospheric transport and photochemistry. A comprehensive error analysis is presented. This includes errors on the slant columns retrieval and errors on the air mass factors which are mainly due to uncertainties in the a priori profile and in the cloud properties. The major features of the retrieved formaldehyde column distribution are discussed and compared with previous CH2O datasets over the major emission regions.

    Since 1999, the NASA/JPL Solar System Educators Program (SSEP) has been the model of a successful master teacher volunteer program. Integrating nationwide volunteers in this professional development program helped optimize agency funding set aside for education. Through the efforts of these volunteers, teachers across the country became familiarized with NASA's STEM (Science, Technology, Engineering and Mathematics) educational materials, schools added these products to their curriculum and students benefitted. The years since 1999 have brought about many changes. There have been advancements in technology that allow more opportunities for telecon and web based learning methods. Along with those advancements have also come significant challenges. With NASA budgets for education shrinking, this already frugal program has become more spartan. Teachers face their own hardships with school budget cuts, limited classroom time and little support for professional development. In order for SSEP to remain viable in the face of these challenges, the program management, mission funders and volunteers themselves are working together to find ways of maintaining the quality that made the program a success and at the same time incorporate new, cost-effective methods of delivery. The group will also seek new partnerships to provide enhancements that will aid educators in advancing their careers at the same time as they receive professional development. By working together and utilizing the talent and experience of these master teachers, the Solar System Educators Program can enjoy a revitalization that will meet the needs of today's educators at the same time as renewing the enthusiasm of the volunteers.

    We discuss the origin of the optical variations in the Narrow line Seyfert 1 galaxy NGC 4051 and present the results of a cross-correlation study using X-ray and optical light curves spanning more than 12 years. The emission is highly variable in all wavebands, and the amplitude of the optical variations is found to be smaller than that of the X-rays, even after correcting for the contaminating host galaxy flux falling inside the photometric aperture. The optical power spectrum is best described by an unbroken power law model with slope $\\alpha=1.4^{+0.6}_{-0.2}$ and displays lower variability power than the 2-10 keV X-rays on all time-scales probed. We find the light curves to be significantly correlated at an optical delay of $1.2^{+1.0}_{-0.3}$ days behind the X-rays. This time-scale is consistent with the light travel time to the optical emitting region of the accretion disc, suggesting that the optical variations are driven by X-ray reprocessing. We show, however, that a model whereby the optical variati...

    Severe acute respiratory syndrome-coronavirus (SARS-CoV) and SARS-like coronavirus are a potential threat to global health. However, reviews of the long-term effects of clinical treatments in SARS patients are lacking. Here a total of 25 recovered SARS patients were recruited 12 years after infection. Clinical questionnaire responses and examination findings indicated that the patients had experienced various diseases, including lung susceptibility to infections, tumors, cardiovascular disorders, and abnormal glucose metabolism. As compared to healthy controls, metabolomic analyses identified significant differences in the serum metabolomes of SARS survivors. The most significant metabolic disruptions were the comprehensive increase of phosphatidylinositol and lysophospha tidylinositol levels in recovered SARS patients, which coincided with the effect of methylprednisolone administration investigated further in the steroid treated non-SARS patients with severe pneumonia. These results suggested that high-dose pulses of methylprednisolone might cause long-term systemic damage associated with serum metabolic alterations. The present study provided information for an improved understanding of coronavirus-associated pathologies, which might permit further optimization of clinical treatments.

    On 20 August 2015, a workshop was held in Barrow, Alaska, which presented the highlights of 12 years of research connecting local indigenous knowledge of landscape processes with scientific research on arctic lakes, tundra changes, and permafrost stability. Seventy-six Iñupiat elders, hunters, and other knowledge-holders from the North Slope villages of Barrow, Atqasuk, Wainwright, Nuiqsut, and Anaktuvuk Pass were interviewed, and over 75 hours of videotaped interviews were produced. The interviews provided information and observations on landforms, lakes, erosion, permafrost degradation and thermokarst, changes in the environment and in animal behavior, human modification of lakes, tundra damage from 4-wheel off-road vehicles, tundra trail expansion, and other phenomena. Community concerns regarding the impact of environmental change on food procurement, animal migration, human travel routes, and the future of subsistence practices were also prominent themes. Following an interview, each videotaped session was logged. Each time an elder pointed to a location on a map and explained a landscape event/observation or told a story, the time-stamp in the video was recorded. Each logged event consisted of a code and a short account of the observation. From these reference sheets, a Geographic Information System (GIS) dataset was created. A logged account for each videotape, with geographic coordinates, event code, and event description is available for each videotape. The goal of the workshop was to report on our findings, thank the community for their support, and collaboratively develop plans for archiving and disseminating this data. A complete video library and searchable, printed and digital issues of the logging dataset for archiving in the communities were also produced. Discussions with administrative personnel at the Tuzzy Library in Barrow and the Inupiat Heritage Center have enabled us to set standards and develop a timeline for turning over the library of

    From the start of the airborne laser surveys in late 2002 until the present, the elevation record for the Amundsen Coast of Antarctica from small-footprint elevation measurements now spans more than a dozen years: Laser-altimetry measurements on tracks spaced tens of km apart are available from ATM, LVIS, and ICESat; Worldview stereophotogrammetry (SP) gives high-resolution snapshots of surface topography for selected parts of the coast, and CRYOSAT gives high-temporal-resolution, spatially dense radar measurements, at modestly lower precision than the other sensors. We present synoptic estimates of elevation change based on judicious combinations of these data. Two sets of techniques yield complementary results: Combining laser-derived elevations with SP DEMs gives an elevation-change map covering most outlets with near-annual resolution between 2003 and the present, while combining Cryosat data with SP DEMs gives a database of radar elevations with improved ambiguity resolution that we process to estimate surface elevation changes between mid 2010 and the present. Firn and accumulation models help reduce the effects of accumulation variability on the derived elevation rates, allowing estimates of steady-atmosphere ("dynamic") mass-change rates. These data reveal variable but increasing mass loss from Thwaites and Haynes glaciers, continuing mass loss from the glaciers draining into the Dotson and Crosson ice shelves, and significant losses on Alison ice stream and Ferrigno glacier on the Bellingshausen coast. There is also evidence for a recent hiatus in strong elevation change in parts of the grounding zone of Pine Island glacier, after nearly a decade of accelerating losses there. We discuss these findings in the context of measured surface speed changes and model estimates of ocean temperature variations.

    2012-01-01

    Full Text Available Cosmogenic isotopes have frequently been employed as proxies of ancient cosmic ray fluxes. On the basis of periodicities of the 10Be time series (using data from both the South and North Poles and the 14C time series (with data from Intercal-98, we offer evidence of the existence of cosmic ray fluctuations with a periodicity of around 30 years. Results were obtained by using the wavelet transformation spectral technique, signal reconstruction by autoregressive spectral analysis (ARMA, and the Lomb-Scargle periodogram method. This 30-year periodicity seems to be significant in nature because several solar and climatic indexes exhibit the same modulation, which may indicate that the 30-year frequency of cosmic rays is probably a modulator agent for terrestrial phenomena, reflecting the control source, namely, solar activity.

    2013-11-01

    The objective of this study was to describe the oral phase of swallowing in individuals with dental malocclusion and to generate data that would contribute to the rehabilitation of those patients. The study was based on the evaluation of the swallowing system through videofluoroscopy on thirty-four children of both genders, aged eight to twelve years old who present with Angle Class II and III dental malocclusions. Thirteen children of similar age and gender presenting normal dental occlusion formed the control group. The results indicated that the oral phase of swallowing is different between individuals with normal occlusion and malocclusion. Dental occlusion types Angle Class II and III did not present a swallowing pattern, independently of the amount of liquid ingested. The swallowing appeared effective in the oral phase of individuals with dental malocclusion, even though adaptations were identified. The outcome, in the absence of a single pattern and the efficiency of the adapted swallowing demonstrates, first a need for additional research investigating orofacial myofunctional treatment for patients with malocclusion and second how such analyses should focus on contributing positively to the rehabilitation of these patients.

    In 2001, an international surveillance initiative was established, utilising a validated larval development inhibition assay to track the susceptibility of cat flea isolates to imidacloprid. In 2009, an Australian node was incorporated into the programme, joining laboratories in the United States and Europe. Field isolates of Ctenocephalides felis eggs were submitted to participating laboratories and, where egg quantity and quality was sufficient, were placed in the imidacloprid discriminating dose bioassay for evaluation. Between 2002 and 2012, a total of 2,307 cat flea isolates were received across all sites; 1,685 submissions (73 %) were suitable for placement into the bioassay. In the Northern Hemisphere, isolate submission rate was influenced by season, with highest numbers submitted between June and October. In Australia, pets with flea infestations could be sourced year-round, and submission rate was largely influenced by programme factors and not climate. A total of 1,367 valid assays were performed between 2002 and 2012 (assay validity data was not recorded in 2001); adult flea emergence 5 % or greater at 3 ppm imidacloprid was observed in 38 of these assays (2.8 %). For these isolates that reached the threshold for further investigation, re-conduct of the assay using either a repeat challenge dose of 3 ppm of imidacloprid or a dose response probit analysis confirmed their susceptibility to imidacloprid. From 2009 to 2012, the Australian node performed valid assays on 97 field isolates from a total of 136 submissions, with no adult emergence observed at the 3-ppm imidacloprid discriminating dose. In addition to reviewing the data generated by this twelve-year initiative, this paper discusses lessons learned from the coordination and evolution of a complex project across geographically dispersed laboratories on three continents.

    To present a case report describing the long-term behaviour of periapical cemento-osseous dysplasia by observing the radiographic changes that took place over a period of 12 years. A review of the pertinent literature is also presented. A healthy 26-year-old white female was referred to the Wilford Hall USAF Medical Center Endodontic Department for evaluation of an asymptomatic radiolucency at the apex of the right mandibular lateral incisor. Following a clinical evaluation that included pulp testing, a diagnosis of periapical cemento-osseous dysplasia (PCOD) was made. No treatment was rendered but follow-up visits were recommended. The patient was subsequently re-evaluated 8 times over a period of 12 years. During that time the lesion changed in appearance, displaying the various phases of PCOD. At the same time, lesions affecting the three adjoining incisors appeared and behaved in a similar manner. At the 12-year recall, the right lateral and both central incisors revealed no evidence of PCOD and an almost normal trabecular pattern of bone could be seen. Misdiagnosis and unnecessary treatment of PCOD may be avoided with careful pulp testing and knowledge of its most common locations of occurrence, radiographic appearances (phases) and benign behaviour. © 2014 International Endodontic Journal.

    Invasive animals can facilitate the success of invasive plant populations through disturbance. We examined the relationship between the repeated foraging disturbance of an invasive animal and the population maintenance of an invasive plant in a coastal dune ecosystem. We hypothesized that feral wild hog (Sus scrofa) populations repeatedly utilized tubers of the clonal perennial, yellow nutsedge (Cyperus esculentus) as a food source and evaluated whether hog activity promoted the long-term maintenance of yellow nutsedge populations on St. Catherine's Island, Georgia, United States. Using generalized linear mixed models, we tested the effect of wild hog disturbance on permanent sites for yellow nutsedge culm density, tuber density, and percent cover of native plant species over a 12-year period. We found that disturbance plots had a higher number of culms and tubers and a lower percentage of native live plant cover than undisturbed control plots. Wild hogs redisturbed the disturbed plots approximately every 5 years. Our research provides demographic evidence that repeated foraging disturbances by an invasive animal promote the long-term population maintenance of an invasive clonal plant. Opportunistic facultative interactions such as we demonstrate in this study are likely to become more commonplace as greater numbers of introduced species are integrated into ecological communities around the world.

    Knowledge of succession rates and pathways is crucial for devising restoration strategies for highly disturbed ecosystems such as surface-mined land. As these processes have often only been described in qualitative terms, we used Markov models to quantify transitions between successional stages. However, Markov models are often considered not attractive for some reasons, such as model assumptions (e.g., stationarity in space and time, or the high expenditure of time required to estimate successional transitions in the field). Here we present a solution for converting multivariate ecological time series into transition matrices and demonstrate the applicability of this approach for a data set that resulted from monitoring the succession of sandy dry grassland in a post-mining landscape. We analyzed five transition matrices, four one-step matrices referring to specific periods of transition (1995-1998, 1998-2001, 2001-2004, 2004-2007), and one matrix for the whole study period (stationary model, 1995-2007). Finally, the stationary model was enhanced to a partly time-variable model. Applying the stationary and the time-variable models, we started a prediction well outside our calibration period, beginning with 100% bare soil in 1974 as the known start of the succession, and generated the coverage of 12 predefined vegetation types in three-year intervals. Transitions among vegetation types changed significantly in space and over time. While the probability of colonization was almost constant over time, the replacement rate tended to increase, indicating that the speed of succession accelerated with time or fluctuations became stronger. The predictions of both models agreed surprisingly well with the vegetation data observed more than two decades later. This shows that our dry grassland succession in a post-mining landscape can be adequately described by comparably simple types of Markov models, although some model assumptions have not been fulfilled and within

    Within the framework of the DRAGON program, a relative long term surveillance, 12 years, of the Poyang and Dongting lakes, considered as key elements of the Yangtze watershed in terms of water resource, flood redaction and for biodiversity maintain has been realized. This was done combing altimetry, in situ measurements, SAR and optical MR and HR time series with a high revisiting frequency of 10 days. A first major output corresponds, particularly within the context of lost of Envisat and Sentinels’ data availability expected in 2014,corresponds to the potential’sanalysis of a large range of MR and HR optical and SAR data for water bodies monitoring in term of quality, potential and accuracy. Over the years, changes in the type of data used are very indicative of a share of the resource available, and also of technological improvement over the years. It can be noticed since 2008, that, the part of HR optical data, Beijing1, DEIMOS, HJ1 A-B has increased significantly. In regards to the two years gap in term of data resource before the availability of the first Sentinel data, some recommendations can be given to insure the monitoring of large water bodies. Thematically specking, major outputs is the characterization of the important inter annual, and intra annual variations in term of water height and water extent of both lakes, variations that are linked with rainfall variations at sub basins and Yangtze basin scales. This 12 years period is marked by general non linear tendencies of water resources decreasing even if two major flood events occurred in 2002 and 2010. Drought tendency and drought intensity has been precised. During winter 2011-2012, EO data analysis allowed given the real size of the water surface extent as 720 km2 when Medias were speaking about 200 km2; the driest winter for the latest decade being the 2003-2004 as shown by the time series comparison. These analysis also highlight the very fast change from extreme stage to another as in June

  17. Twelve Years of Spectroscopic Monitoring in the Galactic Center: The Closest Look at S-stars near the Black Hole

    We study the young S-stars within a distance of 0.04 pc from the supermassive black hole in the center of our Galaxy. Given how inhospitable the region is for star formation, their presence is more puzzling the younger we estimate their ages. In this study, we analyze the result of 12 years of high-resolution spectroscopy within the central arcsecond of the Galactic Center (GC). By co-adding between 55 and 105 hr of spectra we have obtained high signal-to-noise H- and K-band spectra of eight stars orbiting the central supermassive black hole. Using deep H-band spectra, we show that these stars must be high surface gravity (dwarf) stars. We compare these deep spectra to detailed model atmospheres and stellar evolution models to infer the stellar parameters. Our analysis reveals an effective temperature of 21,000–28,500 K, a rotational velocity of 60–170 km s‑1, and a surface gravity of 4.1–4.2. These parameters imply a spectral type of B0–B3V for these stars. The inferred masses lie within 8–14 {M}ȯ . We derive an age of {6.6}-4.7+3.4 Myr for the star S2, which is compatible with the age of the clockwise-rotating young stellar disk in the GC. We estimate the ages of all other studied S-stars to be less than 15 Myr, which is compatible with the age of S2 within the uncertainties. The relatively low ages for these S-stars favor a scenario in which the stars formed in a local disk rather than a field binary-disruption scenario that occurred over a longer period of time.

    Full Text Available Since the introduction of monitoring levels of immunosuppressive medications in our service in July 2000, 1088 kidney transplant patients were received for therapeutic drug monitoring and regular follow-up. The aim of this study was to retrospectively analyze the data on these renal graft patients in Algeria and correlate with our 12 years′ experience with calcineurin inhibitor (CNI measurements. In addition, during this period, we also examined other bioche-mical parameters. The analysis was focused on the difference of effect of cyclosporin A (CsA; 623 patients and Tacrolimus (Tac; 465 patients on lipid and glucose metabolism and their side-effects, if any, on the renal function. The mean age at the time of transplantation was 36.1 years. A great majority of the transplanted kidneys had been taken from living related donors (88.6%. Three-quarters of all grafts were transplanted in our country (79.5%. Dyslipidemia and renal dysfunction were the most common adverse effects of CsA and Tac exposure, with a frequency of 21.4% and 10.3%, respectively. Both the CNIs had a similar effect on the lipid levels. The highest incidence occurred at 3-12 months after renal graft. Tac seemed to have more side-effects on glycemia, causing the onset of diabetes mellitus more than two-fold than CsA (6.9% vs. 3.1%. A significant difference was observed during 12-24 months after transplantation. However, Tac was associated with the most favorable effects on renal function estimated with the Modification of Diet in Renal Disease (MDRD formula.

    2015-02-01

    Full Text Available INTRODUCTION: Perinatal death rate is declining in developed and developing countries and so are perinatal autopsies. In the present days due to wider availability and awareness of prenatal scanning more and more congenital malformations are picked up in e arlier weeks of gestation. This helps in counselling of the couple which usually leads to an informed decision on medical termination of pregnancy. Autopsy performed on such fetuses , yields additional information in many cases. AIMS: The study was carried out to determine how well the prenatal ultrasound findings correlate with autopsy findings and also to determine the cause of death where ultrasound was not performed in patients who had spontaneous intrauterine death and abortion. MATERIALS AND METHODS: T his was a prospective study carried out over a period of two years in the department of pathology at Kamineni Academy of Medical Sciences and Research Centre , Hyderabad , from January 2013 to December 2014. A total of 23 fetal autopsies were performed of wh ich one was a twin pregnancy. Brief maternal history , prenatal ultrasound scans , relevant biochemical markers and genetic studies wherever done , were noted. RESULTS : There were 14 male (60.86% and 8 female (34.78% fetuses , and in one case (4.34% gender could not be identified. Nineteen cases (82.60 % were less than 28 weeks of gestation. Medical termination of pregnancy was done in 13 cases (56.52 % whereas , 10 patients (43.47 % had spontaneous intrauterine death of the fetus. Ultrasound scanning was done in 15 cases (65.21 %. In 13 cases (86.66 % the ultrasound and autopsy findings were correlating whereas in two cases (13.33 % there were findings on imaging study which could not be identified on autopsy. Ultrasound was not done in 8 cases (34.78 % out of which 5 cases (62.5 % showed findings on autopsy which could have led to the fetal demise. Twelve cases (52.17 % were referral cases which had come from other hospitals

    2016-09-01

    Composite resin and amalgam restorations are indicated for the restoration of posterior teeth. With increased esthetic demands, long-term clinical studies are required to evaluate the restorative success and reasons for failure of these materials. The purpose of this retrospective study was to determine the survival and reasons for failure of directly placed 2-surface composite resin restorations and directly placed 2-surface amalgam restorations on premolars placed by Canadian dental students. Using The University of Manitoba's dental management software and paper charts, all 2-surface composite resin and 2-surface amalgam restorations placed on premolars between January 1, 2002, and May 30, 2014, were included. Short-term failure (within 2 years), long-term failure, and reasons for failure were collected. A Kaplan-Meier survival estimate with an associated P value comparing composite resin to amalgam restoration curves was performed using SPSS statistical software. Over 12 years, 1695 composite resin and 1125 amalgam 2-surface premolar restorations were placed. Of these restorations, 134 composite resins (7.9%) and 66 amalgams (5.9%) failed. Short-term failures (2 years or less) consisted of 57 composite resin (4%) and 23 amalgam (2.3%) restorations. Long-term failures (greater than 2 years) consisted of 77 composite resin (4.5%) and 43 amalgam (3.8%) restorations. After 12 years of service, the survival probability of composite resin restorations was 86% and that of amalgam restorations 91.5%. The differences in composite resin and amalgam survival curves were also found to be statistically significant (P=.009 for Log-rank test). The main reasons for failure were recurrent caries and fracture of the tooth being restored. Within the limitations of this study, both composite resin and amalgam restorations had acceptable success rates and similar failure modes. Recurrent caries was still the most common reason for failure. Copyright © 2016 Editorial Council for

    2016-08-01

    The issue of the proper goals of science education and science teacher education have been a focus of the science education and philosophy of science communities in recent years. More particularly, the issue of whether belief/acceptance of evolution and/or understanding are the appropriate goals for evolution educators and the issue of the precise nature of the distinctions among the terms knowledge, understanding, belief, and acceptance have received increasing attention in the 12 years since we first published our views on these subjects. During that time, our own views about these issues have evolved, and this article presents a reconsideration of both these distinctions and the propriety of these goals. In particular, the present paper continues our discussion of the nature of belief as it relates to science education, and more specifically to evolution education. We extend that work to consider the import of the distinction between belief and acceptance.

    The aim of the study was to analyse the effects of smoking, in particular to show its causal role in the development of airflow obstruction, and to look at changes in smoking habits. The study was conducted among 556 men, aged 30 to 54 in 1960, surveyed twice, in 1960 and 1972. The hypothesis of tobacco as a causal factor of airflow obstruction is strengthened, following this study, by three results: 1) FEV1 slope was related to tobacco consumption, even after adjustement for FEV1 level (42 ml/yrs for non-smokers, 51 ml/yrs for heavy smokers); 2) FEV1 loss with age increased with the amount of tobacco consumption: one pack a day smoked for 25 years was equivalent to an aging of 5 years; 3) FEV1 loss decelerated if the subject gave up smoking, thus preventing any further risk. What appeared to be a spontaneous regulation in smoking habits was observed. The men who stopped smoking were those with low respiratory status. In this population, men who were ex-smokers in 1960 and maintained this status until 1972 had a FEV1 slope similar to that of the non-smokers.

    Full Text Available Purpose. The study aims to compare the long-term outcome of conjunctival autograft (CAU and mitomycin C (MMC in double-head pterygium surgery. Methods. This is a follow-up study of a comparative interventional trial. Thirty-nine eyes of the 36 patients with double-head pterygium excision in the original study 12 years ago were recruited for clinical assessment. Seven out of the 36 patients were lost. In the original study, each eye with double-head pterygium was randomized to have pterygium excision with CAU on one “head” (temporal or nasal and MMC on the other “head.” All patients were invited for clinical assessment for conjunctival bed status and the presence of pterygium recurrence in the current study. Results. There was no significant difference between the size, morphology, and type of pterygium among the two treatment groups. The recurrence rate of CAU group and MMC group 12 years after excision was 6.3% and 28.1%, respectively (P=0.020. Among eyes without recurrence, the conjunctival bed was graded higher in the MMC group than the CAU group (P=0.024. Conclusion. The use of conjunctival autograft has a significantly lower long-term recurrence rate than mitomycin C in double-head pterygium surgery.

    The aim of this study was to analyze the safety, treatment characteristics and survival outcomes of Yttrium-90 (Y90) radioembolization for unresectable colorectal carcinoma (CRC) liver metastases refractory to standard of care therapy. A total of 214 patients with CRC metastases were treated with Y90 radioembolization over 12 years. Toxicity was assessed using National Cancer Institute common terminology criteria. Overall survival was analyzed from date of diagnosis of primary cancer, hepatic metastases and from the first Y90. Uni/multivariate analyses were performed. Substratification by era of chemotherapeutics was performed. Most patients were male (60 %) and <65 years old (61 %). Of them, 98 % had been exposed to chemotherapy. Grade 3 lymphocyte, bilirubin, albumin, ALP and AST toxicities were observed in 39 %, 11 %, 10 %, 8 % and 4 % of patients, respectively. Grade 4 lymphocyte and ALP toxicities were observed in 5 % and 3 % of patients, respectively. Median overall survival was 43.0, 34.6, and 10.6 months from date of diagnosis of primary cancer, hepatic metastases and first Y90, respectively. Survival was significantly longer in patients: (1) who received ≤2 cytotoxic drugs (n = 104) than those who received 3 (n = 110) (15.2 vs. 7.5 months, p = 0.0001); and (2) who received no biologic agents (n = 52) compared with those that did (n = 162) (18.6 vs. 9.4 months, p = 0.0001). Multivariate analyses identified ≤2 cytotoxic agents, no exposure to biologics, ECOG 0, tumor burden <25 %, lack of extrahepatic disease and albumin >3 g/dL as independent predictors of survival. In this largest metastatic CRC series published to date, Y90 radioembolization was found to be safe; survival varied by prior therapy. Further studies are required to further refine the role of Y90 in metastatic CRC. (orig.)

  12. Twelve years' experience with direct-to-consumer advertising of prescription drugs in Canada: a cautionary tale.

    Directory of Open Access Journals (Sweden)

    Barbara Mintzes

    Full Text Available BACKGROUND: Direct-to-consumer advertising (DTCA of prescription drugs is illegal in Canada as a health protection measure, but is permitted in the United States. However, in 2000, Canadian policy was changed to allow 'reminder' advertising of prescription drugs. This is a form of advertising that states the brand name without health claims. 'Reminder' advertising is prohibited in the US for drugs that have 'black box' warnings of serious risks. This study examines spending on DTCA in Canada from 1995 to 2006, 12 years spanning this policy shift. We ask how annual per capita spending compares to that in the US, and whether drugs with Canadian or US regulatory safety warnings are advertised to the Canadian public in reminder advertising. METHODOLOGY/PRINCIPAL FINDINGS: Prescription drug advertising spending data were extracted from a data set on health sector spending in Canada obtained from a market research company, TNS Media Inc. Spending was adjusted for inflation and compared with US spending. Inflation-adjusted spending on branded DTCA in Canada grew from under CAD$2 million per year before 1999 to over $22 million in 2006. The major growth was in broadcast advertising, accounting for 83% of spending in 2006. US annual per capita spending was on average 24 times Canadian levels. Celebrex (celecoxib, which has a US black box and was subject to three safety advisories in Canada, was the most heavily advertised drug on Canadian television in 2005 and 2006. Of 8 brands with >$500,000 spending, which together accounted for 59% of branded DTCA in all media, 6 were subject to Canadian safety advisories, and 4 had US black box warnings. CONCLUSIONS/SIGNIFICANCE: Branded 'reminder' advertising has grown rapidly in Canada since 2000, mainly due to a growth in television advertising. Although DTCA spending per capita is much lower in Canada than in the US, there is no evidence of safer content or product choice; many heavily-advertised drugs in Canada

The objective of the present study was to evaluate the seroprevalence of hepatitis A virus antibodies in the Israeli population before and after the introduction of the program. A cross-sectional serosurvey using the National Serum Bank was conducted on 1883 and 2027 serum samples collected before and after introduction of the vaccine, respectively. Serologic tests for the presence of hepatitis A IgG antibodies were performed using an automated enzyme-linked fluorescent assay. The age-adjusted seroprevalence rates of hepatitis A virus antibodies before implementation of hepatitis A vaccination program were 47.1% [95% confidence interval (CI): 44.7%-49.5%] among Jews and 82.8% (95% CI: 79.6%-85.9%) among Arabs, increasing 12 years after to 67.4% (95% CI: 64.7%-70.0%) and 88.2% (95% CI: 86.1%-90.2%), respectively. The seropositivity rate among Jews and Arabs increased significantly among the cohorts included in the program. However, among Jews, a significant increase in seropositivity was also detected among age groups not included in the vaccination program. The decrease in the incidence of hepatitis A in Israel is a consequence of high vaccine uptake, persistent seropositivity rates after vaccination and the considerable number of people vaccinated beyond the program.

    The study investigated the extent to which approaches to work, workplace climate, stress, burnout and satisfaction with medicine as a career in doctors aged about thirty are predicted by measures of learning style and personality measured five to twelve years earlier when the doctors were applicants to medical school or were medical students. Prospective study of a large cohort of doctors. The participants were first studied when they applied to any of five UK medical schools in 1990. Postal questionnaires were sent to all doctors with a traceable address on the current or a previous Medical Register. The current questionnaire included measures of Approaches to Work, Workplace Climate, stress (General Health Questionnaire), burnout (Maslach Burnout Inventory), and satisfaction with medicine as a career and personality (Big Five). Previous questionnaires had included measures of learning style (Study Process Questionnaire) and personality. Doctors' approaches to work were predicted by study habits and learning styles, both at application to medical school and in the final year. How doctors perceive their workplace climate and workload is predicted both by approaches to work and by measures of stress, burnout and satisfaction with medicine. These characteristics are partially predicted by trait measures of personality taken five years earlier. Stress, burnout and satisfaction also correlate with trait measures of personality taken five years earlier. Differences in approach to work and perceived workplace climate seem mainly to reflect stable, long-term individual differences in doctors themselves, reflected in measures of personality and learning style.

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

  1. A 15-year epileptogenic period after perinatal brain injury.

    Science.gov (United States)

    Pisani, F; Pavlidis, E; Facini, C; La Morgia, C; Fusco, C; Cantalupo, G

    Seizures are a frequent acute neurological event in the neonatal period. Up to 12 to 18% of all seizures in newborns are due to perinatal stroke and up to 39% of affected children can then develop epilepsy in childhood. We report the case of a young patient who presented stroke-related seizures in the neonatal period and then developed focal symptomatic epilepsy at 15 years of age, and in whom the epileptic focus was found to co-localize with the site of his ischemic brain lesion. Such a prolonged silent period before onset of remote symptomatic epilepsy has not previously been reported. This case suggests that newborns with seizures due to a neonatal stroke are at higher risk of epilepsy and that the epileptogenic process in these subjects can last longer than a decade.

    Full Text Available Abstract Background Training of neuromuscular control has become increasingly important and plays a major role in rehabilitation of subjects with an injury to the anterior cruciate ligament (ACL. Little is known, however, of the influence of this training on knee stiffness during loading. Increased knee stiffness occurs as a loading strategy of ACL-injured subjects and is associated with increased joint contact forces. Increased or altered joint loads contribute to the development of osteoarthritis. The aim of the study was to determine if knee stiffness, defined by changes in knee kinetics and kinematics of gait, step activity and cross-over hop could be reduced through a knee-specific 12-week training programme. Methods A 3-dimensional motion analysis system (VICON and a force plate (AMTI were used to calculate knee kinetics and kinematics before and after 12 weeks of knee-specific training in 12 males recruited from a cohort with ACL injury 16 years earlier. Twelve uninjured males matched for age, sex, BMI and activity level served as a reference group. Self-reported patient-relevant data were obtained by the KOOS questionnaire. Results There were no significant changes in knee stiffness during gait and step activity after training. For the cross-over hop, increased peak knee flexion during landing (from 44 to 48 degrees, p = 0.031 and increased internal knee extensor moment (1.28 to 1.55 Nm/kg, p = 0.017 were seen after training, indicating reduced knee stiffness. The KOOS sport and recreation score improved from 70 to 77 (p = 0.005 and was significantly correlated with the changes in knee flexion during landing for the cross-over hop (r = 0.6, p = 0.039. Conclusion Knee-specific training improved lower extremity kinetics and kinematics, indicating reduced knee stiffness during demanding hop activity. Self-reported sport and recreational function correlated positively with the biomechanical changes supporting a clinical importance of the

    We examined prevalence of high-level aminoglycoside resistance (HLAR) in Enterococcus faecalis and Enterococcus faecium causing invasive infection in the Minami Ibaraki Area. Ten strains of both species each, recovered from the blood or the cerebrospinal fluid between 2003 and 2014, were randomly selected every year. High-level resistance to gentamicin (HLR-GM) and streptomycin (HLR-SM) was detected in 34% (41 of 120 strains) and 18% (21) of E. faecalis and 9% (11) and 39% (48) of E. faecium, respectively. In comparisons of the proportions among three four-year periods, HLR-SM among E. faecium was significantly lower in the 2011-2014 period. All strains with HLR-GM were positive for the aac(6')-Ie-aph(2″)-Ia gene. The ant(6')-Ia gene was detected in all with HLR-SM except for one E. faecalis strain. The present study showed that prevalence of HLR-GM among E. faecalis and E. faecium causing invasive infection in this area was nearly equivalent to that described in previous studies in Japan and that proportions of strains with HLAR did not vary during the study period except for that of HLR-SM among E. faecium.

    Proximity data were collected in a captive breeding group of gorillas (Gorilla gorilla gorilla) at the San Diego Wild Animal Park (currently called the San Diego Zoo Safari Park) twice a year (spring and fall periods) for over 12 years, by using a convenient method in which individuals less than 5 m from each animal in the group were recorded by scan sampling, approximately once per hour. Immature females from infancy to young adulthood maintained relatively frequent proximity to both their mothers and the silverback male and spent little time alone (no animals within 10 m), with relatively large individual differences. On the other hand, immature males decreased the time spent near their mothers and the silverback male and increased the time spent alone with increasing age. Therefore, sex differences in proximity to mothers and the silverback male became apparent after late juvenility. Some adult females maintained increased frequency of proximity to the silverback male than that by other females over the 12-year period, indicating the presence of long-term, stable proximity relationships between the silverback male and the adult females. Such long-term, stable proximity relationships were also observed among adult females. Some association patterns reported in wild gorillas, such as frequent proximity between adult females with dependent offspring and the silverback male and close relationships between related females, were not observed in the present study. The idiosyncratic or individual factors influencing some association patterns were easily reflected in captive situations.

    Full Text Available We report a case of rabies viral encephalitis in a 48-year-old male with an unusually long incubation period, historically suspected to be more than 20 years. The case was referred for histological diagnosis following alleged medical negligence to the forensic department. The histology and immunocytochemical demonstration of rabies viral antigen established the diagnosis unequivocally. The case manifested initially with hydrophobia and aggressive behavior, although he suddenly went to the bathroom and drank a small amount of water. History of dog bite 25 years back was elicited retrospectively following clinical suspicion. There was no subsequent history to suggest nonbite exposure to a rabid dog to consider recent event causing the disease, although this cannot be totally excluded.

    Using the data on sunspot groups compiled during 1879-1975, we determined variations in the differential rotation coefficients and during the solar cycle. The variation in the equatorial rotation rate is found to be significant only in the odd numbered cycles, with an amplitude ∼ 0.01 rads-1. There exists a good anticorrelation between the variations of the differential rotation rate derived from the odd and even numbered cycles, suggesting existence of a `22-year' periodicity in . The amplitude of the variation of is ∼ 0.05 rad s-1.

    Environmental exposure to volatile organic compounds (VOCs) in ambient air is one of a number of concerns that the First Nation Community of Fort McKay, Alberta has related to development of Canada's oil sands. An in-depth investigation of trends in ambient air VOC levels in Fort McKay was undertaken to better understand the role and possible significance of emissions from Alberta's oil sands development. A non-parametric trend detection method was used to investigate trends in emissions and ambient VOC concentrations over a 12-year (2001-2012) period. Relationships between ambient VOC concentrations and production indicators of oil sands operations around Fort McKay were also examined. A weak upward trend (significant at 90% confidence level) was found for ambient concentrations of total VOCs based on sixteen detected species with an annual increase of 0.64μg/m(3) (7.2%) per year (7.7μg/m(3) increase per decade). Indicators of production (i.e., annual bitumen production and mined oil sands quantities) were correlated with ambient total VOC concentrations. Only one of 29 VOC species evaluated (1-butene) showed a statistically significant upward trend (p=0.05). Observed geometric (arithmetic) mean and maximum ambient concentrations of selected VOCs of public health concern for most recent three years of the study period (2010-2012) were below chronic and acute health risk screening criteria of the U.S. Agency for Toxic Substances and Disease Registry and U.S. Environmental Protection Agency. Thirty-two VOCs are recommended for tracking in future air quality investigations in the community to better understand whether changes are occurring over time in relation to oil sands development activities and to inform policy makers about whether or not these changes warrant additional attention.

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

    Full Text Available We use time-series analyses to characterize the effects of recent climate variability upon the local physical conditions at 11 study sites along the northern-central coast of Chile (29-34°S. Environmental indices show that the 1° Bakun upwelling index in this coastal region has fluctuated in time, starting from a stable period around the 1980's, peaking during the mid 90s, decreasing during the next ten years and increasing at a steep rate since 2010. Upwelling intensity decreased with increasing latitude, showing also a negative correlation with climate patterns (El Niño3 sea surface temperature-SST anomalies and the Multivariate El Niño Index. We hypothesize that the impacts of climate variability on upwelling events seem to be spatially heterogeneous along the region. Non-sheltered locations and, particularly, sites on prominent headlands show an immediate (lag = 0 and negative correlation between local SST, upwelling events and wind stress. We suggest that near-shore thermal conditions are closely coupled to large-scale forcing of upwelling variability and that this influence is modulated through local topographic factors.

    Negligence claims in the UK NHS has increased over the last 30 years. The aim of this present study was determine the number of claims and the cost of litigation in Bariatric Surgery and compare it to similar other specialties. Data was received from NHS Litigation Authority (NHSLA) in response to Freedom of Information data request. There was a total of 7 claims, of which 4 were successful. The total pay out sum was £210,000 in 10 years. This is a very low amount compared to other surgical specialties. This low level of litigation probably indicates that the current bariatric surgical services in the NHS are delivering safe care with good patient satisfaction. This needs to be carefully considered prior to changing the payment tariffs for bariatric surgery. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd. All rights reserved.

The peak torque of the pectoralis major is significantly decreased after conservational treatment of a total rupture. We suppose that surgical intervention is better choice.Methods We retrospectively evaluated 12 patients who were diagnosed with distal pectoralis major muscle rupture and underwent operation in our institute from 1993 to 2007. All patients were male with a mean age of 32 (19-54) years. In 4 patients, tendon reconstruction was accomplished by fixing the tendon to the humerus using sutures passed through predrilled humeral bone tunnels. In 8 patients, tendon reconstruction was accomplished by directly suturing the muscle to the tendon. All patients followed an accelerated rehabilitation protocol. Treatment results were evaluated according to the following criteria: (1) visual analogue pain scale, (2) isokinetic strength measurements, (3) range of motion of shoulder joint, (4) cosmetic result, and (5) postoperative sports activity performance. In this study, we aimed to describe our surgical technique of reconstruction of the rupture of pectoralis major muscle and to summarize the clinical results of the operative treatment.Results At the final follow-up examination (6.5 years postoperatively), only nine patients were available for evaluation. Three of them had excellent results, and five had good results, while one had poor results. Eight of the patients were able to return to their preinjury level of sporting activity. In summary, 89% of the patients achieved excellent or good results. Conclusion Surgical treatment by anatomic tendon repair and accelerated rehabilitation can make recovery of strength and function of the pectoralis major muscle.

    Full Text Available Background. Eye injuries constitute a leading problem in eye surgery worldwide, as well as at our department. Their treatment is very complex, and requires a wide surgical knowledge and surgical skills supported by the material and the equipment. Aim. To analyze the results of vitreoretinal surgery on 647 patients with severe penetrating eye injuries in the period from 1991 to 1998. Methods. The study included a retrospective analysis of the treatment of 647 injuries, out of which 500 were penetrating, and 147 were severe contusion injuries. Attention was payed to the penetrating injuries with intraocular foreign body (IOFB, to the number of the performed pars plana vitrectomies (VPP, to the number of the extirpated foreign bodies, as well as to the number of the conventional retinal ablation surgeries. Also significant proved the consequences of contusion injuries, and the method of their complete surgical management - the surgery combined with the implantation of intraocular lens, as well as their functional results. Results. Inside the said period, 558 VPPs were performed, 60 conventional retinal ablation surgeries, and 29 combined anterior/posterior segment surgeries. VPP was applied in 286 (51.3% of the cases with penetrating injuries with IOFB, and in 58 (10.4% of the cases with contusion injuries. VPP in one eye was applied in 464 (83% of the cases, in both eyes in 65 (11.8% of the cases, and in a single eye in 29 (5.2% of the cases. Following VPP, silicone oil tamponade was done in 352 (63% of the cases, air tamponade in 123 (22% of the cases, and Ringer-BSS tamponade in 83 (15% of the cases. Laser photocoagulation (LFC was performed in 484 (87% of the cases, cryocoagulation in 45 (8%, while neither of them was done in 29 (5% of the cases. In all of the cases of the conventional retinal ablation (n = 60, a placement of a serclage was applied and exocryocoagulation was performed, while in the 52 cases a placement of a scleral flap was

    A large-scale assessment of polycyclic aromatic hydrocarbons (PAHs) from the 1991 Gulf War oil spill was performed for 2002-2003 sediment samples (n = 1679) collected from habitats along the shoreline of Saudi Arabia. Benthic sediment toxicity was characterized using the Equilibrium Partitioning Sediment Benchmark Toxic Unit approach for 43 PAHs (ESBTU{sub FCV,43}). Samples were assigned to risk categories according to ESBTU{sub FCV,43} values: no-risk (<=1), low (>1-<=2), low-medium (>2-<=3), medium (>3-<=5) and high-risk (>5). Sixty seven percent of samples had ESBTU{sub FCV,43} > 1 indicating potential adverse ecological effects. Sediments from the 0-30 cm layer from tidal flats, and the >30-<60 cm layer from heavily oiled halophytes and mangroves had high frequency of high-risk samples. No-risk samples were characterized by chrysene enrichment and depletion of lighter molecular weight PAHs, while high-risk samples showed little oil weathering and PAH patterns similar to 1993 samples. North of Safaniya sediments were not likely to pose adverse ecological effects contrary to sediments south of Tanaqib. Landscape and geomorphology has played a role on the distribution and persistence in sediments of oil from the Gulf War. - Risk Assessment of PAHs in shoreline sediments 12 years after the Gulf War oil spill.

    Full Text Available Background: Iodine deficiency disorder (IDD creates major public health problems in India, including Gujarat. The Bharuch district is a known iodine deficiency endemic area. This study was conducted to estimate the prevalence of goiter in primary school children; to determine the median urinary iodine concentration; to assess the level of iodine in salt samples at the household and retail shop levels; and to study the profile of salt sold at retail shops. Methods: This study was carried out by using the 30-cluster survey method in the primary schools of the rural areas in Bharuch district. A total of 70 students, including five boys and five girls from the first to seventh classes, who were present in class on the day of the visit were selected randomly for goiter examination from each village. Urine samples were collected from one boy and one girl from each class in each cluster. From each community, a maximum of two boys and two girls from each standard in the same age group were examined and also salt samples were tested from their households. From each village, one retail shop was visited and the salt purchased from those shops was immediately tested for iodine with spot kits. Results: We found a goiter prevalence of 23.2% (grade 1 - 17.4% and grade 2 - 5.8%. As the age increased, the goiter prevalence decreased except in nine-year-olds. The median urinary iodine excretion level was 110 μg/L. An Iodine level > 15 ppm was found in 93% of the salt samples tested at the household level. Conclusion: The present study showed moderate goiter prevalence in primary school children in the Bharuch district of Gujarat and an inadequate iodine content of salt at some household levels.

    Background Awareness of cardiovascular disease (CVD) risk has been linked to taking preventive action in women. The purpose of this study was to assess contemporary awareness of CVD risk and barriers to prevention in a nationally representative sample of women and to evaluate trends since 1997 from similar triennial surveys. Methods and Results A standardized survey about awareness of CVD risk was completed in 2009 by 1142 women ≥25 years of age, contacted through random digit dialing oversampled for racial/ethnic minorities, and by 1158 women contacted online. There was a significant increase in the proportion of women aware that CVD is the leading cause of death since 1997 (P for trend=<0.0001). Awareness among telephone participants was greater in 2009 compared with 1997 (54% versus 30%, P<0.0001) but not different from 2006 (57%). In multivariate analysis, African American and Hispanic women were significantly less aware than white women, although the gap has narrowed since 1997. Only 53% of women said they would call 9-1-1 if they thought they were having symptoms of a heart attack. The majority of women cited therapies to prevent CVD that are not evidence-based. Common barriers to prevention were family/caretaking responsibilities (51%) and confusion in the media (42%). Community-level changes women thought would be helpful were access to healthy foods (91%), public recreation facilities (80%), and nutrition information in restaurants (79%). Conclusions Awareness of CVD as the leading cause of death among women has nearly doubled since 1997 but is stabilizing and continues to lag in racial/ethnic minorities. Numerous misperceptions and barriers to prevention persist and women strongly favored environmental approaches to facilitate preventive action. PMID:20147489

    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.

    Periodical organisms, such as bamboos and periodical cicadas, are very famous for their synchronous reproduction. In bamboos and other periodical plants, the synchronicity of mass-flowering and withering has been often reported indicating these species are monocarpic (semelparous) species. Therefore, synchronicity and periodicity are often suspected to be fairly tightly coupled traits in these periodical plants. We investigate the periodicity and synchronicity of Strobilanthes flexicaulis, and a closely related species S. tashiroi on Okinawa Island, Japan. The genus Strobilanthes is known for several periodical species. Based on 32-year observational data, we confirmed that S. flexicaulis is 6-year periodical mass-flowering monocarpic plant. All the flowering plants had died after flowering. In contrast, we found that S. tashiroi is a polycarpic perennial with no mass-flowering from three-year individual tracking. We also surveyed six local populations of S. flexicaulis and found variation in the synchronicity from four highly synchronized populations (>98% of plants flowering in the mass year) to two less synchronized one with 11-47% of plants flowering before and after the mass year. This result might imply that synchrony may be selected for when periodicity is established in monocarpic species. We found the selective advantages for mass-flowering in pollinator activities and predator satiation. The current results suggest that the periodical S. flexicaulis might have evolved periodicity from a non-periodical close relative. The current report should become a key finding for understanding the evolution of periodical plants.

    High-risk alcohol consumption among university students is well documented. Several types of intervention have proved to be effective in reducing alcohol consumption. This study examines the 2-year outcome of 2 different alcohol intervention programs at university halls of residence. Ninety-eight university halls of residence (with 556 students) were cluster randomized to 2 different intervention groups: a brief skills training program (BSTP) with interactive lectures and discussions, a twelve-step-influenced (TSI) program with didactic lectures by therapists trained in the 12-step approach, and a control group. All students completing the baseline assessment received personalized feedback by mail. Students responded to mailed follow-up questionnaires after 1, 2, and 3 years, including alcohol use disorders identification test (AUDIT; years 2 and 3), short index of problems (SIP), and estimated blood alcohol concentration (eBAC). All groups significantly reduced their AUDIT scores from baseline to the second year follow-up, with no significant differences between the groups. Seventy-seven percent of the students belonged to a population with high-risk consumption, using the AUDIT cut-off scores of 8 and 4 for men and women, respectively. Students with high-risk alcohol consumption showed significant differences in AUDIT score reduction in favor of the BSTP compared with controls, and had a tendency to show better results than the TSI intervention (p=0.06). Similar trends could be seen using SIP and eBAC. The TSI did not differ significantly from the control group within the group of students with high-risk alcohol consumption. This study suggests that a BSTP is effective as an intervention in students with high-risk alcohol consumption.

    OBJECTIVE Hepatic angiosarcoma (HAS), a lethal disease, is the most common sarcoma arising in the liver. Little information about the epidemiology, etiology, diagnosis and management of HAS has been reported. Increased familiarity with this disease will facilitate correct diagnosis and help to improve management of this condition in the future.The objective of this study was to describe cases of hepatic angiosarcoma and to discuss the etiologic, diagnostic, therapeutic features and prognosis of this tumor. This report not only serves to give more evidence of the relationship between hepatic angiosarcoma and carcinogenic exposure, but also demonstrates the key points in different methods of diagnosis and the optimal treatment of hepatic angiosarcoma.METHODS Twelve cases of hepatic angiosareoma were analyzed retrospectively, representing the different character in clinical presentations and laboratory computed tomographical scans; pathological data and treatment are described. Clinical and biologic follow-up was carried out for two years after surgical treatment.RESULTS There were nine men and three women varying in ages from 57 to 71 years with an average of 64.3 years. Ten patientshad a history of exposure to vinyl chloride or thorotrast. Mild or moderate abdominal pain and bloating, abdominal mass and fever were the common clinical presentations. Tumors were visualized by ultrasonography and CT scans in all patients. Biochemical profiles yielded variable results and proved to be of little value in detection or diagnosis. Surgical resection was feasible for each patient who was treated as follows: two wedge resections, six segementectomies and four bisegmentectomies. Five patients received Neoadjuvant chemotherapy postoperatively. The survival rate of those cases was poor. The maximum survival time was fourteen months. The mean survival time for this chemotherapeutic group was 11 months. The difference between the survival time of those treated with an operation

    Sex differences in declarative memory and visuospatial ability are robust in cross-sectional studies. The present longitudinal study examined whether sex differences in cognition were present over a 10-year period, and whether age modified the magnitude of sex differences. Tests assessing episodic and semantic memory, and visuospatial ability were administered to 625 nondemented adults (initially aged 35-80 years), participating in the population-based Betula study at two follow-up occasions. There was stability of sex differences across five age groups and over a 10-year period. Women performed at a higher level than men on episodic recall, face and verbal recognition, and semantic fluency, whereas men performed better than women on a task-assessing, visuospatial ability. Sex differences in cognitive functions are stable over a 10-year period and from 35 to 90 years of age.

  3. Geodetic Constraints on Mantle Q at Periods from a Fortnight to 18.6 Years

    Seismic observations have provided numerous constraints on the earth's spherically-averaged mantle anelasticity at periods of tens of minutes and shorter. Meanwhile, post-glacial rebound and other geodynamic studies provide information at periods of a few thousand years and longer. However, constraints at intermediate periods are scarce. Such constraints could be useful in trying to connect the seismic anelastic models with the longer-period visco-elastic behavior. Here we will describe constraints on anelasticity in this intermediate range of periods as obtained from earth tide and earth rotation observations. We discuss results from: (1) VLBI observations of the monthly and fortnightly tidal variations in rotation rate; (2) satellite laser ranging observations of the 18.6-year tidal variations in the earth's gravitational field; and (3) astrometric and geodetic observations of the 14-month Chandler Wobble period and damping. We find that these observations are consistent with a nearly frequency-independent mantle Q stretching from seismic periods all the way out to the 14-month Chandler Wobble period; but that Q appears to decrease significantly between 14-months and 18.6-years.

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

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

    The aim of this study was to determine the prevalence of oral malignant melanoma along with age range and site of presentation over an 11-year period in Iran. The files of Tehran Cancer Institute served as a source of material for this study. Files were systematically searched for all malignant melanomas and oral malignant melanomas during an 11-year period. Prepared slides and demographic data from the biopsy files were reviewed. Statistical analysis was performed with the use of SPSS. Of the 38,993 cases accessed during the 11-year period, 569 were identified as malignant melanomas, while 41 cases among this group had malignant oral melanomas comprising 0.1% of the total cases and 7.2% of all the malignant melanoma lesions. The palate was the most common location for oral malignant melanoma. Thus, all melanocytic lesions in the palate should be viewed with caution, and biopsy is recommended to rule out melanoma.

    Full Text Available The purpose of the present study was to describe the prevalence, incidence and geographic variation of glaucoma in Denmark in the period from 1996 to 2011. Moreover, the aim was to identify the treatment patterns of glaucoma within the studied period.All Danish citizens were included throughout the study period. The National Prescription Registry was used to identify all claimed prescriptions for glaucoma medication.A total of 116,592 incident glaucoma patients were identified. Average age at onset was 66 years (range: 0-105 years, 55% were women. The prevalence of glaucoma increased from 0.79% to 1.72% during the investigated period. In 2011 glaucoma affected 3.76% of the population above 50 years and 10% in patients above 80 years. The age-specific incidence rate of glaucoma seemed to be constant and the increasing prevalence was primarily attributed to an aging population. We found the highest prevalence of glaucoma in the capital region of Denmark. Within the studied period the use of prostaglandin analogs and combination drugs increased, whereas the use of β-blockers, carbon anhydrase inhibitors and parasympathomimetic drugs decreased (p<0.001. Finally, the use of α2-adrenergic agonists remained unchanged. A total of 75% of the patients were treated with two or more glaucoma medications.Over all, the present study is the first to assess the frequency and the development of glaucoma in Denmark over a 15-year period. We find that glaucoma affects a little less than 2% of the total population and increases with age to reach a prevalence of more than 10% amongst people above 80 years. Generally, the present study is the largest nation-wide study ever made and must be a close-to-real-life-picture of the utilization of glaucoma medication on a national scale. Our findings confirm other recent estimations on an increasing burden of glaucoma globally.

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

    2012-04-01

    Periods characterized with the high ozone concentrations are usually associated with very high air temperature and antycyclonic conditions or meridional circulation. A 15-year (1997 - 2011) maximum daily temperature records from GSOD NOAA archive was analyzed for 20 stations in Central Europe. For each year the number of days with the maximum temperature exceeding 25oC and 30oC was calculated. For years with a positive anomaly of the number of the hot days the data were analyzed to identify exact dates and the duration of such events. This allows classification of the high temperature period as "heat waves" (periods with maximum temperature exceeding 30oC lasting at least 3 consecutive days) and hot weather periods (periods with maximum temperature exceeding 25oC and high daily average temperature). These two types of high temperature are usually associated with different air masses inflow - subtropical from the south or transformed polar from westerly directions. This indicates also the differences in contribution of transboundary transport of ozone and its precursors. For selected high temperature episodes the ozone pollution was assessed based on AirBase (1997-2009) and national database (2010-2011). The analysis covered the 8-hour running average and daily maximum concentration of ozone near the surface. Also, the contribution to the SOMO35 index during selected episodes will be calculated as a diagnostic for adverse health effects. Since the two analyzed types of hot weather periods have different origin in terms of synoptic scale situation, an attempt will be made to answer whether there are differences in the intensity of ozone episodes during selected hot weather periods. The outcome from the study will be useful for the interpretation of modelling results for air quality in future climate.

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

    This paper proposes the use of two-factor models (age-period and age-cohort models) to estimate age, period, and cohort effects on pulmonary function by using the data collected in a 24-year longitudinal study in the Netherlands from 1965 to 1990. The analysis included 18,363 pulmonary function measurements on 6,148 subjects aged 20-54 years at the initial visit. The subjects were grouped into four birth cohorts (before 1923, 1923-1934, 1935-1946, and after 1946) and four survey periods (1965-1972, 1973-1978, 1979-1984, and 1985-1990). In the age-cohort model, the decrement in forced expiratory volume in 1 second (FEV1) associated with a yearly increase in age was 28.3 +/- 3.7 ml/year for a man 176 cm tall and 16.0 +/- 1.9 ml/year for a woman 163 cm tall. The estimated acceleration of decline with aging was significant for both men (beta = -0.212; standard error = 0.079 ml) and women (beta = -0.346; standard error = 0.058 ml). Compared with that of the cohort born before 1923, the average level of FEV1 was estimated to increase by 156, 277, and 379 ml, respectively, for the three younger cohorts in men (p = 0.01) and by 133, 213, and 328 ml for the three younger cohorts in women (p linear age effect on FEV1 was 36.2 +/- 4.2 ml/year for a man and 30.5 +/- 2.3 ml/year for a woman. The age quadratic term was significant for women, but not for men. Average FEV1 was estimated to be increased by 141, 169, and 250 ml, respectively, for the periods 1973-1978, 1979-1984, and 1985-1990 in men and by 131, 138, and 219 ml in women. These period effects were significant for both men and women. In summary, this study applied the two-factor models to estimate cross-sectional and longitudinal effects of aging on FEV1 and demonstrated significant period and cohort effects, which could be attributed in part to changes in air pollutants, respiratory infections, vaccinations, types of cigarettes, diet, and lifestyles over time.

    Sea level movements with quasi-periodicity of 430,000 years are identified in the marine sedimentary units of the Eastern Gulf Coastal Plain of Mississippi, Alabama and Georgia which represent a 5.8 million year record of strandline displacement during Paleocene time. Principal component analysis of the benthic foraminiferal fauna yielded six assemblages which when combined with two other qualitatively derived assemblages provided paleoecologic information which clearly reflects the influence of paleocirculation and paleoclimatic regime of the Eastern Gulf Coastal Plain. The presence of the planktonic foraminiferal taxa Subbotina trinidadensis and Planorotalites pseudomenardii as well as paleolatitudes ranging from 15{degree} N (for the Campeche Shelf) to 25{degree} N (for the Coastal Plain) emphasizes a paleoclimatic regime which is dominantly tropical. A paleoceanographic model was derived which suggests that normal marine waters were brought into the Gulf of Mexico by two major currents. Strandline displacements are related to transgressive and regressive sea level movements in an ice free Paleocene world. The well delineated 430,000 year quasi-periodic cycle observed in the sea level curve is identified as being astronomical in character. These results support the view that changes in the Earth's orbit may trigger changes in the geometry of the Earth's surface in a way which causes sea level to oscillate with a quasi-periodicity of 430,000 years.

    Full Text Available Background: Proper knowledge of the patterns of sexually transmitted diseases (STDs in different geographical regions is necessary for evolving proper strategies for control of these diseases. Aims: To study the pattern of STDs and to analyze the changes during a ten-year period from 1990 among patients attending Medical College Hospital, Kottayam Methods: Case records of 686 patients with STDs who attended the outpatient wing of the Department of Dermatology and Venereology were studied. Results: There were 504 males and 182 females in the total of 686 patients. Marital contact alone was reported by 123 (67.6% female patients. Genital ulcer diseases (GUDs accounted for the maximum number of STDs, with 504 cases (73.5%, followed by condyloma acuminatum (17.5% and gonorrhea (10.1%. Forty-three patients had multiple infections. The total number of patients during the first year of study was 129, while it was 41 during the last year. Bacterial STDs showed a striking reduction in numbers. The decline was less marked in the case of viral STDs. Conclusion: The majority of patients had genital ulcer diseases. Spouses were the most common source of infection for female patients. There was a marked decline in the number of patients with various STDs during the ten-year period. The decline was more evident in the bacterial STDs resulting in an apparent increase of the viral STDs towards the end of the period of study.

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

In 1979-82 it was 2.17 per 1,000 livebirths, 1.23 for children born at term and 0.94 for preterms, which means that the rising trend since the beginning of the 1970s persisted. The most pronounced rise, from 0.18 per 1,000 livebirths in the period 1967-70 to 0.67 in 1979-82 was found in the subgroup of preterms with spastic/ataxic diplegia. The severity of motor disability and the relative frequency of mental retardation, infantile hydrocephalus and epilepsy among preterm CP children successively increased over the same period of time. The livebirth prevalence of CP in term infants increased slightly but non-significantly during the period 1967-82. The birthweight-specific prevalence of CP per 1,000 newborns surviving the first week of life increased in all birthweight groups during the period 1967-82, significantly for birthweights below 1,500 g and over 2,500 g. The rising prevalence of CP was concomitant with a parallel fall in perinatal mortality, especially in very preterm infants. In the 1980s, severely multi-handicapped, very preterm children, only exceptionally seen among CP children born in the 1960s and 1970s, has become a matter of concern.

    Rural development has long been the focus of China’s central and local governments. Since the late 2000 s, rural areas have presented new transformation features and development trends. To stimulate rural transformation and development in the 13 th Five-Year Plan period, this paper reviews major ideas on rural development in related disciplines. This study also summarizes main rural transformation features, including the aging population, hollow villages, changes in the allocation of land resource, semi-urbanization, and regional differences in rural development. Finally, it also provides suggestions for planning tactics in the 13 th Five-Year Plan period, such as making differentiated rural development strategies, exploring new methods to stimulate rural stock land planning and use, and enforcing relevant policy and management reforms.

    Full Text Available Intruduction: Hysterectomy is one of major surgeries. Pregnancy, delivery and postpartum period make the operation even more difficult as it is forced and complicated by various pathological conditions that develop over that time. Objective: The purpose of study was to analyze the frequency of hysterectomy, indications to undertake it and complications associated with the removal of the uterus in pregnancy and during perinatal and postpartum period. The study analyzed the cases of hysterectomies in perinatal and postpartum period performed over the 17-year clinical material from the Department of Gynaecology and Obstetrics, SZOZ, Lipsko in the years 1985–2001. Material and methods : The material for analysis were medical records of 15 women who developed complications in pregnancy, perinatal and postpartum period, which were absolute indication to perform hysterectomy. The following parameters were analyzed: patient’s age, number of deliveries, the way pregnancies were terminated, the way present pregnancy was terminated, complications, indications to Caesarean section and perinatal and postpartum hysterectomy, type of hysterectomy performed, other associated procedures and complications. Results : In total 15 hysterectomies were performed in the period of study which accounts for 0.10% all deliveries. The material revealed the following causes for hysterectomy: placental pathologies (46.7%, inflammatory conditions of internal sex organs (20.0%, uterine atonia after delivery (13.3%, injuries of sex organs (13.3%. Elective hysterectomy in that period was performed in one patient (6.7%. The risk factors predisposing to complications resulting in hysterectomy were history of Caesarean sections in 10 patients (66.7% and multiple spontaneous deliveries. Complications associated with hysterectomy which enforced additional operations were noted in two cases (13.3%. Total hysterectomy was performed in 8 patients (53.3% including hysterectomy with

    Frequent use (FU) of hospital services impacts on patients and health service expenditure. Studies examining FU in emergency departments and inpatient settings have found heterogeneity and the need to differentiate between potentially preventable FU and that associated with ongoing management of complex conditions. Psychosocial factors have often been reported as underpinning or exacerbating the phenomena. Most FU studies have been limited by time, to a single study site, or restricted to specific diagnoses or patient groups. This study provides a comprehensive description of adult patient characteristics, conditions and risk factors associated with FU, based on admissions to the five public hospitals in the Northern Territory (NT) of Australia over a nine year period. The study population is distinctive comprising both Aboriginal and non-Aboriginal patients. Data on all inpatient episodes in NT public hospitals between 2005 and 2013 was analysed to identify patients with any FU (four or more episodes within any 12-month period) and measure FU duration (number of FU years) and intensity (mean number of episodes per FU year). Pregnancy, alcohol-related and mental health condition flags were assigned to patients with any episode with relevant diagnoses during the study period. Multivariate analysis was used to assess factors associated with any FU, FU duration and FU intensity, separately for Aboriginal and non-Aboriginal patients. Of people with any inpatient episodes during the study period, 13.6% were frequent users (Aboriginal 22%, non-Aboriginal 10%) accounting for 46.6% of all episodes. 73% of frequent users had only one FU year. Any FU and increased FU duration were more common among individuals who were: Aboriginal; older; female; and those with a pregnancy, alcohol or mental health flag. Having two or more alcohol-related episodes in the nine-year period was strongly associated with any FU for both Aboriginal (odds ratio 8.9, 95% CI. 8.20-9.66) and non

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

    OBJECTIVE To analyze the incidence rate and trend of thyroid cancer in Tianjin over a recent 20-year period.METHODS A method of descriptive epidemiology was used to study the occurrence of thyroid cancer.RESULTS During 1981~2001, the average incidence rate of thyroid cancer was 1.770 per 100,000 with a male to female incidence ratio of 1:2.74, the occurrence being higher in females than in males. Thyroid cancer incidence increased gradually with time over the 20 years in both males and females, especially the incidence peaked in females of 35~50 years of age.CONCLUSION The rapid increase in the incidence rate of thyroid cancer, especially in females, suggests that further research on the risk factors and preventive efforts related to high-risk women should be conducted.

    Severe floods triggered by intense precipitation are among the most destructive natural hazards in Alpine environments, frequently causing large financial and societal damage. Potential enhanced flood occurrence due to global climate change would thus increase threat to settlements, infrastructure, and human lives in the affected regions. Yet, projections of intense precipitation exhibit major uncertainties and robust reconstructions of Alpine floods are limited to the instrumental and historical period. Here we present a 2500-year long flood reconstruction for the European Alps, based on dated sedimentary flood deposits from ten lakes in Switzerland. We show that periods with high flood frequency coincide with cool summer temperatures. This wet-cold synchronism suggests enhanced flood occurrence to be triggered by latitudinal shifts of Atlantic and Mediterranean storm tracks. This paleoclimatic perspective reveals natural analogues for varying climate conditions, and thus can contribute to a better understanding and improved projections of weather extremes under climate change.

    Full Text Available The objective of this study was to evaluate the quality of raw milk in different production systems and its variation throughout the year. The data were collected from 943 dairy farms in the South, Central-West and Central regions of the state of Minas Gerais, and in Vale do Paraíba, in the state of São Paulo, Brazil. The data were collected in the period from January 2009 to September 2011, in a total of 18,206 samples. The properties were divided into confinement, semi-confinement and extensive production systems. The evaluated factors were somatic cell count (SCC, total bacterial count (TBC and protein and fat contents. There was no effect of production system on the contents of protein, fat and SCC. Total bacterial count, however, was affected by production. Seasonal variations were found for SCC, TBC, protein and fat; the highest protein values were found from March to June; the highest fat contents were obtained from May to August; and TBC and SCC, from December to March. The production system does not interfere with the percentage of fat and protein and SCC of the milk. However, confinement systems present a better TBC content. Both month and year are factors that interfere with TBC, SCC, protein and milk fat, and the best patterns are found in the coldest periods of the year.

  3. Resistance studies of erythromycin and rifampin for Rhodococcus equi over a 10-year period

    Full Text Available Abstract This study sought to determine whether an increase in resistance of Rhodococcus equi to the antibiotics rifampin and erythromycin occurred over a 10-year period. This was carried out by the use of E test strips for rifampin and erythromycin to determine the MIC (minimum inhibitory concentration values of Rhodococcus equi to this combination of antibiotics. The findings of this study indicated that there was an increase in resistance of Rhodococcus equi to rifampin and erythromycin over the 10-year period. The MIC for rifampin increased from 0.081 μg/ml in 1996 to 0.187 μg/ml in 2006 and from 0.258 μg/ml for erythromycin during the years prior to 2000 to 0.583 μg/ml in 2006. This finding suggests that there may be a problem in the treatment of Rhodococcus equi infections in foals in the future, particularly as the number of drugs available for treatment of Rhodococcus equi infection is limited because of the intracellular capabilities of this bacterium. Antibiotics used in its treatment have to be able to penetrate the polysaccharide cell wall of Rhodococcus equi as well as the alveolar macrophages in which the bacterium is capable of surviving.

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

    Cholangiocarcinomas (CCAs) are tumors with a poor prognosis and a lower quality of life (QoL). The aim of this study was to evaluate the survival rate and quality of life in CCA patients. We prospectively enrolled 133 patients diagnosed with CCA in the 3rd Medical Clinic, Cluj Napoca, over a 4-year period (2005-2009). The QoL was evaluated by means of a QoL questionnaire (EORTC QLQ-C30). The mean age of the patients was 65 +/- 10.6 years: 55% were males. 71% of the patients had hilar tumor (Klatskin), 23% distal and 6% intrahepatic CCA (IH). Only 11.3% of the patients were eligible to receive curative treatment. The 1-year overall survival was 22.3 +/- 4.4% and the 2-year survival was 3.4 +/- 2.1%. The patients receiving metallic stents had better survival than those receiving plastic stents (40.4% vs 12.5% at 1 year, 9.1% vs 5.0% at 2 years, respectively). The 1-year survival was significantly improved for patients who underwent surgery plus adjuvant chemotherapy. The post-therapy QoL demonstrated a less improvement in Klatskin tumor patients than in patients with other types of tumors. Endoscopic palliative therapy allowed a faster community reintegration, but with variable evolution. The highest 2-year survival rate was 5.5%. Slightly longer survival was recorded when chemotherapy was added and also after endoscopic placement of metallic stents. Endoscopic biliary decompression improved the QoL faster than surgery.

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

    The purpose of this study was to analyze the evolution of smoking among Psychology students at the University of Santiago de Compostela (Spain) over a ten-year period (1986-2006). We also assessed the extent of knowledge of the Spanish health legislation on tobacco (Ley 28/2005) and its effect on smoking. We administered a questionnaire to representative samples of students from the 1st year of their Psychology course to the 5th year, on four occasions. In the academic year 1996-1997 (N = 835), 34% of the sample claimed to be daily smokers; in 1999-2000 (N = 842), the figure was 35.2%; in 2003-2004 (N = 835) it was 31.9%; and in 2006-2007 (N = 688), it was 22.8%. Moreover, in the last assessment, 97.1% of the sample reported being aware of the legislation (Ley 28/2005) and 41.9% of the smokers claimed that it had some degree of influence on their smoking. It can be stated that, although overall current prevalence of smoking is similar to that of 10 years ago, a significant change is observed in the profile of smokers. This change is expressed in lower levels of nicotine dependence and a decrease in the percentage of daily smokers, together with an increase in occasional smokers.

    A 22-year-old male with recurrent periods of coughing and nasal discharge was unable to work and cooperate. A bronchoscopy revealed high amounts of leucocytes and no eosinofils, acute inflammation and > 105/ml Streptococcus pneumoniae susceptible to penicillin. The symptoms relapsed after penicillin and at the age of 24 the patient was CT-scanned which revealed bilateral sinusitis, mastoiditis and bronchiectasis. Treatment with azithromycin and a weight loss programme (from 156 kg) improved the health of the patient, who was an orangutan. This highlights the benefit of cooperation between medical doctors and veterinarians.

    This manuscript reports the treatment trends in a pediatric dentistry clinic from 1980 to 1992 and discusses their implication in clinical teaching. Analysis of the records of the senior year pediatric dentistry students indicated: no significant change with time in the patients/student ratio, the number of preformed crowns, pulpotomies, and pulpectomies by student or by patient; a significant decrease in the number of one-surface and > or = 2-surface restorations by student and by patient; a significant increase in the number of pit-and-fissure sealants and preventive resin restorations by student and by patient. During the thirteen-year period, the students performed an average of 7.3 one-surface; 12.9 > or = 2-surface restorations; 5.5 preformed crowns; 6.4 pit-and-fissure sealants; 2.4 pulpotomies. There was a significant increase with time in the number of students who performed pit-and-fissure sealants.

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

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

    Mannheimia haemolytica isolated from feedlot cattle were tested for tulathromycin resistance. Cattle were sampled over a 3-year period, starting 12 months after approval of tulathromycin for prevention and treatment of bovine respiratory disease. Nasopharyngeal samples from approximately 5,814 cattle were collected when cattle entered feedlots (N = 4) and again from the same cattle after ≥60 days on feed. The antimicrobial use history for each animal was recorded. Mannheimia haemolytica was isolated from 796 (13.7%) entry samples and 1,038 (20.6%) ≥ 60 days samples. Of the cattle positive for M. haemolytica, 18.5, 2.9, and 2.4% were administered therapeutic concentrations of tulathromycin, tilmicosin, or tylosin tartrate, respectively. In addition, 13.2% were administered subtherapeutic concentrations of tylosin phosphate in feed. In years one and two, no tulathromycin-resistant M. haemolytica were detected, whereas five isolates (0.4%) were resistant in year three.

    We have constructed a visual light curve of the symbiotic star MWC covering the last 87 years of its history. The data were assembled from the literature and from the AAVSO data bank. Most of the periodic components of the system brightness variation can be accounted for by the operation of 3 basic clocks of the periods P1=19000 d, P2=1943 d and P3=722 d. These periods can plausibly, and consistently with the observations, be attributed to 3 physical mechanisms in the system. They are, respectively, the working of a solar-like magnetic dynamo cycle in the outer layers of the giant star of the system, the binary orbit cycle and the sidereal rotation cycle of the giant star. MWC 560 is the 7th symbiotic star with historical light curves that reveal similar basic characteristics of the systems. The light curves of all these stars are well interpreted on the basis of current understanding of the physical processes that are the major sources of the optical luminosity of these symbiotic systems.

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

    Traumatic brain injury is a leading cause of death and disability in childhood. A retrospective study of all paediatric head injuries admitted to the neurosurgical unit for the West of Scotland over a 10-year period was performed to assess the impact of the National Institute for Health and Clinical Excellence head injury guidelines on the admission rate and to determine the associated risk factors, causes, severity and outcomes of these injuries. There were 564 admissions between 1998 and 2007. The median age at presentation was nine years and two months. There was no change in the admission rate, injury mechanism or severity of head injury admitted over the period studied. A relationship was observed between the Scottish Index of Multiple Deprivation Score and the incidence of head injury (P = 0.05). Alcohol was reported as a causative factor in only a small number of cases, and moderate to severe head injuries were more commonly identified as a result of road traffic accidents.

    PurposeEndonasal dacryocystorhinostomy (END-DCR) is a relatively novel approach that has recently been shown in some studies to provide similar success rates to the more traditional external approach for the treatment of nasolacrimal duct obstruction (NLDO). However, a range of success rates using this approach are reported within the literature and the majority of oculoplastic surgeons are still favouring the external approach. The purpose of this study was to review the anatomical and subjective success rates of END-DCRs performed over a 7-year period.Patients and methodsWe provide a review of the success rates of 288 END-DCRs for the treatment of acquired NLDO performed over a 7-year period by a single oculoplastic surgeon in Sydney, Australia. We describe the operative technique used and define anatomical success as demonstrated patency of the nasolacrimal drainage system at 10 weeks postoperatively while subjective success is defined as complete resolution or significant improvement of symptoms as reported by patients at the same time point.ResultsIn our study, we were able to demonstrate that out of 288 END-DCRs, an average anatomical success rate of 89.6% and an average subjective success rate of 81.3% were achievable.ConclusionsWe conclude that the success rates using our endonasal approach remain similar to those obtained using the external approach, as reported within the literature, and may be considered as a primary treatment option for acquired NLDO.

    Aims and objective: In the present study, an attempt was made to assess the level of skeletal maturation and period of accelerated growth in 70 boys and 70 girls between the ages (8+ and (14+ years using CVMS index. Materials and methods: Lateral cephalogram of 140 individuals were selected, i.e. 70 girls and 70 boys, each of age group from 8+ to 14+ years. It is observed that CVMS index used is highly significant for this purpose. It is observed that this index is highly effective for this purpose. Conclusion: Females′ vertebrae mature earlier than males at each stage. The maturation rate is not constant between the various stages and period of accelerated growth is experienced at different ages and levels in males and females. Need arises to confirm that early maturation in females is not because of their smaller sized vertebra. Further, the time duration recorded between the two subsequent stages is different not because the changes required to be done by nature is different. Longitudinal growth studies of the jaws proper are desired to be conducted for this purpose.

    @@ Power industry is an important infrastructure for national economic and social development. In the 10th Five-Year Plan period, power institutional reform in China has gained important progress, the basic realization of separation between government and enterprises, as well as between power plants and power grids, the formation of competitive situation in power generation field and power enterprises' vitality have been strengthened;along with power tariff reform incessantly deepening, regional power market initiating and power legal construction further strengthening, the construction of power regulatory system achieving progression. In the course of pushing forward power institutional reform, power safety operation, power personnel's stability and rapid growth of power industry have been ensured,which forcefully supported national economic and social development. However, power institutional reform has achieved but an intermediate result, the mission of reform has not yet completed and some new conditions and problems have arisen. In the 11th Five-Year period, we shall firmly grasp the favorable opportunity of power supply alleviation,insist on proceeding from China's reality, assimilate foreign successful experience, consolidate reform achievement and promote power industry's sustained and healthy development,then people's high quality and inexpensive power service can be ensured.

    Tumors of the digestive system are considered to be a public health problem because of their elevated mortality rate. In Mexico, gastric cancer and colon cancer rank fourth and fifth, respectively, following tracheal, bronchial, and lung cancer, and there has been an increase in their frequency in the last few years. However, there are no specific studies that have evaluated their epidemiologic behavior in Veracruz. To determine the frequency of digestive system cancer in five health institutions in the city of Veracruz and to describe its epidemiologic behavior over a five-year period. Annual statistics from the following hospitals were reviewed: the Instituto Mexicano del Seguro Social, the Secretaría de Salud, the Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado, Petróleos Mexicanos, and the Secretaría de la Defensa Nacional within the time frame of January 2005 to December 2009. Diagnoses based on histopathology were recorded, along with patient age and sex. A total of 1803 cases of digestive tract cancers were detected: 52% were men and 48% were women. A yearly increase in the number of cases was observed with colon cancer being in first place, followed by stomach cancer and rectal cancer. The increase in digestive system cancer cases over the last five years in Veracruz underlines the need to evaluate the implementation of screening programs for the at-risk population and to study the different etiologic factors involved in its manifestation.

Ophthalmological examination revealed a solid mass in the left conjunctival semilunar fold. An excitional biopsy was peformed, revealing an amyloid deposition. The patient was referred to the Internal Medicine Department for systemic study. All studies were negative for systemic amyloidosis. Throughout ten years of follow-up study, the patient has shown neither conjunctival recurrence nor any evidence of systemic amylodosis. Despite the fact that several authors have described ocular amyloidosis as an ophthalmologic manifestation of systemic amyloidosis, conjunctival location of amyloidosis is a very rare condition. Amyloid characterization in ocular structures should not be considered a final diagnosis since involvement of systemic underlying diseases must be ruled out. We report a case of localized conjunctival amyloidosis with a ten-year follow-up period that excluded ocular or systemic diseases.Keywords: conjuctival amyloidosis, ocular amyloidosis, hyaline protein

    Premarital sex increases the risk of unintended pregnancy and sexually transmitted infections including HIV if unprotected and contraception is not used. Thus, the objective of this study was to assess premarital sex in the last twelve months and its predictors among regular undergraduate students of Wollega University. A cross-sectional survey using pretested, structured questionnaire was conducted on a total of 704 regular undergraduate students of Wollega University from February to March, 2014. We used multistage sampling technique to recruit study participants. Binary and multivariable logistic regressions were performed using SPSS version 20 to assess predictors of premarital sex. Statistical significance was determined through a 95% confidence level. Wollega University youths who had premarital sex in the last twelve months were 28.4%; 55.5% of them did not use condom during last sex while 31.3% engaged in multiple sex. Being male [Adjusted Odds Ratio (AOR)(95% Confidence Interval(CI))=2.7(1.58-4.75)], age 20-24 years [AOR(95%CI)=2.8(1.13-7.20)], training on how to use condom [AOR(95%CI)=1.7(1.17-2.46)], being tested for HIV [AOR(95%CI)=2.3(1.48-3.53)], using social media frequently [AOR(95%CI)=1.8(1.14-2.88)], having comprehensive knowledge of HIV [AOR(95% CI)=1.5(1.01-2.10)], alcohol use [AOR (95%CI)=2.2(1.31-3.56)] were associated with increased odds of premarital sex in the last twelve months. Nearly one-third of regular undergraduate students of the university were engaged in premarital sex in the last twelve months. Being male, using social media frequently and alcohol use were associated with increased odds of premarital sex in the stated period. Thus, higher institutions have to deliver abstinence messages alongside information about self-protection.

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

  8. Periodic 18.6-year and cyclic 11-year induced drought and flood in northeastern China and some global implications

    Currie, Robert Guinn; Fairbridge, Rhodes W.

    The general patterns of climatic evolution in China during the Holocene are reviewed, and following the postglacial eustatic rise of sea-level and the institution of the East Asian Monsoon, the systems and principal fluctuations are found to be concordant with those operating elsewhere in the globe. China's unique wealth of written history provides an abundance of proxy data on the climatic record and that record now furnishes a basis for analysing both long-term and short-term fluctuations, as well as sunspot behavior, that together provide an insight into extraterrestrial forcing. Recent Chinese work suggests a solar forcing, but our own studies suggest rather that a lunar tidal component, reinforced at times by the solar element may prove more important. Analysis of a drought-flood index for Peking (Beijing) in northeastern China since A.D. 1470 supports evidence (Hameed et al., 1983) for both periodic lunar nodal 18.6-year and solar cyclic 11-year induced drought-flood in the region. The nodal term exhibits bistable phasing with respect to epochs of tidal maxima (for our century epochs occurred at 1917.5, 1936.1, 1954.7 and 1973.3), a phenomenon previously found in drought-flood proxy data for South America (Currie, 1983), India (Currie, 1984a), North America (Currie, 1984d), and Africa (Hameed and Currie, 1985; Currie and Hameed, 1985). Solar cycle epochs of drought-flood are tabulated for the past two centuries, and compared with those from North America and Africa.

  9. Explaining the 11-year periodicity in Neptune's atmosphere with Voyager 2 data

    2017-04-01

    Long-duration observations of Neptune's brightness at two visible wavelengths, made since the 1970s by Lockwood and co-workers [e.g. 1], give a disk-averaged estimate of variations in the planet's clouds and atmospheric aerosol. Brightness variations have previously been associated with the 11-year solar cycle [1], through two solar-modulated mechanisms, firstly, ultraviolet-related colour changes [2], or galactic cosmic ray (GCR)-related nucleation effects on atmospheric particle formation. Over 40 years of brightness data (1972-2014) are used here to show, with physically realistic modelling, that ultraviolet and GCR are likely to be modulating Neptune's atmosphere in combination rather than as alternatives. Existence of the cosmic ray mechanism is further supported by the response of Neptune's atmosphere to an intermittent 1.5- to 1.9-year periodicity during the mid-1980s. This occurred in GCR and, critically for its use in mechanism discrimination, not the solar ultraviolet. This periodicity was detected both at Earth, and in GCR measured by Voyager 2, which was close to Neptune at that time. The similar coincident variability in Neptune's brightness suggests nucleation onto GCR ions. Both GCR and ultraviolet particle modulation mechanisms are expected to occur more rapidly than the subsequent atmospheric transport processes.[2] [1] Lockwood, G. W. & Thompson, D. T.

    Royal Perth Hospital (RPH) has become Western Australia's only designated adult major trauma facility since a previous study of vascular trauma was conducted in 2001 at the same facility. The aim of this study is to identify changes in vascular trauma patterns over the two study periods and compare these changes with international literature. All individuals presenting to RPH between January 2000 and December 2010 with vascular injury were identified from a prospective trauma database for this descriptive study. Injuries were classified using the Abbreviated Injury Score (AIS). The incidence of vascular trauma as a percentage of total trauma increased over the two study periods. The current 10-year study included 45 164 patients on the trauma database, of which 1205 patients (2.6%) sustained 1335 vascular injuries, an increase from 1% in the previous 5-year study at the same facility. Males aged 20-29 years were more frequently injured. Blunt trauma occurred more frequently than penetrating. The extremities, particularly the upper limbs were most commonly injured. The most common causes of injury for each region were as follows; motorbike crash (MBC), motor vehicle crash (MVC) and stabbing (neck, thorax and abdomen), MBC and MVC (lower limb) and piercing injuries (upper limb). Injury Severity Score (ISS) and mortality 43% (32 of 75) were highest for thoracic injuries, particularly thoracic aorta injury. Mortality rate has decreased. Vascular injuries in Western Australia are increasing. MVC are the most common cause of life threatening injury. Road safety interventions targeting young males are likely to reduce trauma. © 2013 Royal Australasian College of Surgeons.

    Full Text Available Abstract Background Recent reports have documented a leveling-off of survival rates in preterm infants through the 1990's. The objective of this study was to determine temporal changes in illness severity in very low birth weight (VLBW infants in relationship to the outcomes of death and/or severe IVH. Methods Cohort study of 1414 VLBW infants cared for in a single level III neonatal intensive care unit in Delaware from 1993–2002. Infants were divided into consecutive 3-year cohorts. Illness severity was measured by two objective methods: the Score for Neonatal Acute Physiology (SNAP, based on data from the 1st day of life, and total thyroxine (T4, measured on the 5th day of life. Death before hospital discharge and severe intraventricular hemorrhage (IVH were investigated in the study sample in relation to illness severity. The fetal death rate was also investigated. Statistical analyses included both univariate and multivariate analysis. Results Illness severity, as measured by SNAP and T4, increased steadily over the 9-year study period with an associated increase in severe IVH and the combined outcome of death and/or severe IVH. During the final 3 years of the study, the observed increase in illness severity accounted for 86% (95% CI 57–116% of the variability in the increase in death and/or severe IVH. The fetal death rate dropped from 7.8/1000 (1993–1996 to 5.3/1000 (1999–2002, p = .01 over the course of the study. Conclusion These data demonstrate a progressive increase in illness in VLBW infants over time, associated with an increase in death and/or severe IVH. We speculate that the observed decrease in fetal death, and the increase in neonatal illness, mortality and/or severe IVH over time represent a shift of severely compromised patients that now survive the fetal time period and are presented for care in the neonatal unit.

    The aim of this study was to evaluate the results of postoperative radiotherapy in a case of perihilar cholagiocarcinoma by analyzing overall survival rate, patterns of failure, prognostic factors for overall survival, and toxicity. Between January 1998 and March 2008, 38 patients with perihilar cholangiocarcinoma underwent a surgical resection and adjuvant radiotherapy. The median patient age was 59 years (range, 28 to 72 years), which included 23 men and 15 women. The extent of surgery was complete resection in 9 patients, microscopically positive margins in 25 patients, and a subtotal resection in 4 patients. The tumor bed and regional lymphatics initially received 45 Gy or 50 Gy, but was subsequently boosted to a total dose of 59.4 Gy or 60 Gy in incompletely resected patients. The median radiotherapy dose was 59.4 Gy. Concurrent chemotherapy was administered in 30 patients. The median follow-up period was 14 months (range, 6 to 45 months). The 3-year overall survival and 3-year progression free survival rates were 30% and 8%, respectively. The median survival time was 28 months. A multivariate analysis showed that differentiation was the only significant factor for overall survival. The 3-year overall survival was 34% in R0 patients and 20% in R1 patients. No statistically significant differences in survival were found between the 2 groups (p=0.3067). The first site of failure was local in 18 patients (47%). No patient experienced grade 3 or higher acute toxicity and duodenal bleeding developed in 2 patients. Our results suggest that adjuvant RT might be a significant factor in patients with a positive margin following a radical resection. However, there was still a high locoregional recurrence rate following surgery and postoperative radiotherapy. Further study is necessary to enhance the effect of the adjuvant radiotherapy.

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

    2011-01-01

    The paper introduces a new approach to estimating the T-year return-period wave height (TRPW),i.e.the wave height expected to occur in T-year,from two sets of observed extreme data and on the basis of the maximum entropy principle.The main points of the approach are as follows.1) A maximum entropy probability density function (PDF) for the extreme wave height H is derived from a Euler equation subject to some necessary and rational constraints.2) The parameters in the function are expressed in terms of the mth moment of H.3) This PDF is convenient to theoretical and practical applications as it is simple and its four parameters are easy to be determined from observed extreme data.An example is given for estimating the TRPW in 50 and 100 years by the present approach and by some currently used methods using observed data at two hydrographic stations.The comparison of the estimated results shows that the present approach is quite similar to the Pearson-Ⅲ and Gumbel methods.

    2016-12-01

    It is shown that "active longitudes" for the sunspots of old and new cycles manifest themselves approximately in the same longitudinal intervals and remain for several 11-year cycles. To be more accurate, they vanish in some cycles but then appear again at the same longitudinal intervals in the other cycles. The entire period is characterized by a total of four active longitudes. The old-cycle sunspots observed at low equatorial latitudes in the Northern and Southern Hemispheres are characterized by a shift by ≈180°, which indicates antipodality of the active longitudes in the Northern and Southern Hemispheres. In the case of highlatitude sunspots (new-cycle sunspots), the best correlation is observed for the shift of ≈90°. There is supposedly a dependence of the rotation speed of active longitudes on the secular cycle.

    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.).

    Full Text Available Background: Learning involves acquiring new knowledge and skills, and changing our ways of thinking, acting, and feeling. Learning in relation to living with diabetes is a lifelong process where there is limited knowledge of how it is experienced and established over time. It was considered important to explore how learning was developed over time for persons living with diabetes. Aim: The aim of the study was to identify patterns in learning when living with diabetes, from recently being diagnosed, and over a 3-year period. Materials and methods: A longitudinal qualitative descriptive design was used. Thirteen participants, with both type I and type II diabetes, were interviewed at three different occasions during a 3-year period. Qualitative content analysis was used in different steps in order to distinguish patterns. Findings: Five main patterns of learning were identified. Two of the patterns (I and II were characterized by gradually becoming comfortable living with diabetes, whereas for one pattern (IV living with diabetes became gradually more difficult. For pattern V living with diabetes was making only a limited impact on life, whereas for Pattern III there was a constant management of obstacles related to illness. The different patterns in the present study showed common and different ways of learning and using different learning strategies at different timespans. Conclusion: The present study showed that duration of illness is not of importance for how far a person has come in his own learning process. A person-centered care is needed to meet the different and changing needs of persons living with diabetes in relation to learning to live with a lifelong illness.

    Temporal increases in the incidence of herpes zoster (HZ) have been reported but studies have examined short study periods, and the cause of the increase remains unknown. We examined the long-term trend of HZ. A population-based cohort study was conducted in Olmsted County, Minnesota, using data from 1945-1960 and 1980-2007. Medical records review of possible cases was performed to confirm incident cases of HZ, the patient's immune status, and prescribing of antivirals for HZ. We examined the relative change in the temporal trend in the incidence rates before and after the introduction of the varicella vaccination program. Of the 8017 patients with HZ, 58.7% were females and 6.6% were immunocompromised. The age- and sex-adjusted incidence rate of HZ increased from 0.76 per 1000 person-years (PY) (95% confidence interval [CI], .63-.89) in 1945-1949 to 3.15 per 1000 PY (95% CI, 3.04-3.26) in 2000-2007. The rate of increase across the time period was 2.5% per year after adjusting for age and sex (adjusted incidence rate ratio, 1.025 [95% CI, 1.023-1.026]; P 4-fold over the last 6 decades. This increase is unlikely to be due to the introduction of varicella vaccination, antiviral therapy, or change in the prevalence of immunocompromised individuals. © The Author 2016.

    Purpose: To show the follow-up of a case of vitelliform mac-ular dystrophy with morphological and visual functional tests over an 8-year period. Methods:.Retrospective review of medical records..The mor-phological examination included color photography,.fluores-cein angiography, and ocular coherence tomography (OCT). The visual functional tests included visual acuity, electro-ocu-logram (EOG) and multifocal electroretinography (mfERG). The patient was observed for 8 years, from 2003 to 2011. Results:.During the follow-up,.the improvement of sensory retinal detachment and reduction of yellow-white deposit were observed with color photography and fluorescein angiography. OCT revealed a decrease in sensory retinal detachment and subretinal hyper-reflective deposits; both of these morphologi-cal changes were correspondent. Visual acuity was maintained throughout the follow-up..The Arden ratio of EOG was de-creased. The amplitudes of mfERG were decreased but slightly increased during the follow-up. Conclusion:.The retinal morphological changes and visual function slightly improved in this case of vitelliform macu-lopathy. The prognosis is good. (Eye Science 2014; 29:165-169)

    Full Text Available Background: Encephalocele is the protrusion of the cranial contents beyond the normal confines of the skull through a defect in the calvarium and is far less common than spinal dysraphism. The exact worldwide frequency is not known. Aims and Objectives: To determine the epidemiological features, patterns of encephalocele, and its postsurgical results. Materials and Methods: The study was carried from year July 2012 to June 2015. Patients with encephalocele were evaluated for epidemiological characteristics, clinical features, imaging characteristics, and surgical results. Results: 20 encephaloceles patients were treated during the study period. Out of these 12 (60% were male and 8 (40% female. Age range was 1 day to 6 years. The most common type of encephalocele was occipital 12 (60%, occipito-cervical 4 (20%, parietal 2 (10%, fronto-nasal 1 (5%, and fronto-naso-ethmoidal 1 (5%. One patient had a double encephalocele (one atretic and other was occipital with dermal sinus tract and limited dermal myeloschisis. Other associations: Chiari 3 malformation (2, meningomyeloceles (4, and syrinx (4. Three patients presented with rupture two of whom succumbed to meningitis and shock. Seventeen patients treated surgically did well with no immediate surgical mortality (except a case of Chiari 3 malformation who succumbed 6 months postsurgery to unrelated causes. Shunt was performed in 4 cases. Conclusion: The most common type of encephalocele is occipital in our set up. Early surgical management of encephalocele is not only for cosmetic reasons but also to prevent tethering, rupture, and future neurological deficits.

    Full Text Available Background and Objectives: Hemoglobinopathies are autosomal recessive inherited diseases more commonly seen in Mediterranean countries. Hereditary blood diseases including B-thalassemia and sickle cell anemia are important health problems. In our study we aimed to analyze the results of the premarital hemoglobinopathy screening test for a 6 years period in Hatay region. Material and Methods: The study sample comprised the couples attending to the Mother and Child Health Care Center in Hatay for premarital hemoglobinopathy screening from 2004 to 2009. Hemoglobin chain analyses of 87.830 couples were evaluated. RESULTS: 175.660 people were screened at total. The prevalence of beta thalassemia trait, sickle cell anemia trait, sickle cell anemia, beta thalassemia major, beta-thalassemia intermedia, alpha-thalassemia, alpha-thalassemia trait was found as 13.921 (7,9%, 6.074 (3,4%, 631 (0.35%, 132 (0.07%, 118 (0.06%, 9 (0.005%, 150 (0.08% respectively. 72 newborns with beta-thalassemia were diagnosed as a result of the marriage of the carrier couples in 6 years. Conclusions: Hatay is a high risk region for beta-thalassemia and sickle cell anemia trait. In countries with high prevalence of hemoglobinopathies, a premarital screening program and counseling is needed to decrease the prevalence.

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

    Environmental and bio-ecological changes, some administrative and political mistakes, and global warming seriously affect the behaviors of ticks in Turkey and globally. The global public sensitivity toward tick infestations has increased along with increases in tick-borne diseases (TBDs). Recently, the World Health Organization (WHO) developed a new political concept, "One Health," for specific struggle strategies against tick infestations and TBDs. To highlight the importance of the issue, the WHO had declared the year 2015 for vector-borne diseases and adopted the slogan "small bites big threat". In global struggle strategies, the epidemiological aspects and dynamics of increasing tick populations and their effects on the incidence of the TBDs mainly with zoonotic characteristics have been specifically targeted. In Turkey, during the last century, approximately 47 tick species, including eight soft and 39 hard tick species in three and six genera belonging to Argasidae and Ixodidae, respectively, had already been reported. In this article, the recorded tick species, regional infestations, and medical and veterinary importance in Turkey were chronologically reviewed based on a 100-year period between 1916 and 2016.

    Full Text Available Aim. To study the evolution of impaired fasting glucose (IFG, considering glucose and HbA1c levels and risk factors associated, in a period of 6 years. Methods. We studied 94 subjects with impaired fasting glucose (IFG that were diagnosed in 2005 and followed up to 2012. Glucose and HbA1c levels were determined. A descriptive analysis of contingence charts was performed in order to study the evolution in the development of type-2 diabetes mellitus (T2DM. Results. Twenty-eight of ninety-four subjects became T2DM; 51/94 remained with IFG; and 20/94 presented normal fasting glucose. From the 28 diabetic subjects, 9 had already developed diabetes and were under treatment with oral hypoglycemic agents; 5 were diagnosed with plasma glucose < 126 mg/dL, but with HbA1c over 6.5%. In those who developed diabetes, 15/28 had a family history of T2DM in first relative degree. Also, diabetic subjects had a BMI significantly higher than nodiabetics (t test: P < 0.01. The individuals that in 2005 had the highest BMI are those who currently have diabetes. Conclusion. The IFG constitutes a condition of high risk of developing T2DM in a few years, especially over 110 mg/dL and in obesity patients.

    Following the changes in October 1990 in the payment system for children's dental treatment within the General Dental Service in the UK there has been widespread concern that repercussions would be felt in other branches of dentistry. The aim of this survey was to investigate the referral of children for specialist care to the Department of Child Dental Health in Newcastle upon Tyne after the changes in 1990, so that consultant clinics and the provision of advice and treatment could be targeted more effectively. Information was obtained from the patients' referral letters and from their hospital records between March 1991 and March 1993. There were 513 referrals (excluding those for orthodontic treatment, extractions under general anaesthesia and acute emergencies), the number more than doubling during the 2-year survey period. 83% of these patients lived within 15 miles of the hospital. 84% of these referrals were from general dental practitioners, and the greater proportion were from those who graduated within the previous 4 years. The most common reason for referral involved behaviour problems. Changes in the payment system that occurred in 1990 may have been a contributory factor in explaining these findings.

    2012-06-01

    We examined reports of sexual orientation identity stability and change over a 10-year period drawing on data from the National Survey of Midlife Development in the United States (MIDUS I and II) and tested for three patterns: (1) heterosexual stability, (2) female sexual fluidity, and (3) bisexual fluidity. Fifty-four percent of the 2,560 participants were female and the average age was approximately 47 years. At Wave 1, 2,494 (97.42%) reported a heterosexual identity, 32 (1.25%) a homosexual identity, and 34 (1.33%) a bisexual identity and somewhat more than 2% reported a different sexual orientation identity at Wave 2. Although some support for each hypothesis was found, initial sexual orientation identity interacted with gender to predict a more complex pattern. For the sample as a whole, heterosexuality was the most stable identity. For women, bisexuality and homosexuality were equally unstable and significantly less stable than heterosexuality, suggesting that sexual orientation identity fluidity is a pattern that applies more to sexual minority women than heterosexual women. For men, heterosexuality and homosexuality were both relatively stable compared to bisexuality, which stood out as a particularly unstable identity. This pattern of results was consistent with previous findings and helps to address methodological limitations of earlier research by showing the characteristics of a population-based sample of heterosexual, homosexual, and bisexual identified men and women over time.

    The largest series examining the cytological diagnosis of coccidioidomycosis was reported more than 20 years ago and only considered fine needle aspiration (FNA) specimens from pulmonary nodules. Since then, there has been a substantial increase in the incidence of the disease in endemic regions. The aims of this study were to examine the spectrum of Coccidioides in all cytologic specimens and detail their diagnostic and clinical features. The prevalence of infection is also examined against temperature and precipitation data. The Department of Pathology database was retrospectively searched for cases diagnosed as coccidioidomycosis. Climate report was obtained from National Weather Service Forecast Office. Statistical analysis was carried out using JMP version 11.2.0. The presence of Coccidiodes was microscopically diverse with immature spherules, variably sized spherules, endosporulating spherules, empty spherules, and ruptured spherules being observed. Bronchoalveolar lavages demonstrated the greatest number of different forms of Coccidioides and were associated with acute inflammatory response. Granulomas were rare and mostly seen in lymph nodes and extra pulmonary sites. A necrotic background with paucity of inflammation was frequently seen in lung FNA. Immune competent patients outnumbered immunocompromised patients, illustrating the importance of considering the diagnosis in all patients. The reported association between rainfall and peak prevalence was not observed in our study. Coccidioides has diverse cytological appearance and varied host response depending on the site and type of preparation examined. In endemic areas, the disease should be considered in all patients, independent of immune status, and throughout the year. © 2016 Wiley Periodicals, Inc.

    The star HO 161387 first caught our eyes when we were reading an article on ~ Aurigae stars by K. O. Wright in Vistas in Astronomy No. 12. This was some 8 or 9 years ago. Aurigae stars are eclipsing binaries formed by a cool supergiant K star and a very much smaller and holter mainsequence (more or less normal) B star. Out of eclipse the B star dominates the blue spectral region, but a pure K-type spectrum is found in eclipse. The drastic spectral changes lor HO 161387 can be seen in Fig 1c and 1d. Periods for these binaries are in the range of 2 to 10 years. The general benefit 01 ~ Aurigae star studies is the possibility of direct determination 01 physical parameters of the components such as masses and radii. In practice, what one does observe is the change in radial velocity of the stars as they orbit around their common centre 01 gravity and the change in magnitude as the light from the B star is eclipsed by the K supergiant. There is also the possibility of studying the structure of the atmosphere of a K supergiant manifested by spectral changes occurring as the point light of the B star shines through the outer parts of the K star c1ose to the total eclipse. Besides Aurigae itsell only the stars 31 and 32 Cygni have been studied in greater detail.

    Human African trypanosomiasis (HAT), also referred to as "sleeping sickness", is caused by the parasite Trypanosoma brucei. Diagnosing imported HAT outside endemic areas is difficult and diagnosis is often delayed. We report a case of imported human African trypanosomiasis caused by Trypanosoma brucei gambiense with an unusually long incubation period of at least 7 years. A 33 year old male African patient, a former resident of Cameroon, presented with a 4-month history of progressive personality changes. A few weeks before presentation the patient had first been admitted to a psychiatric ward and received antidepressant treatment, until a lumbar puncture showed pleocytosis and then antibiotic treatment for suspected neuroborreliosis was initiated. The patient continued to deteriorate during antibiotic treatment and became increasingly lethargic. Under antiparasitic and anti-inflammatory treatment, the condition of the patient gradually improved over the following months and he recovered completely after 24 months of follow-up. This well-documented case illustrates typical difficulties in establishing the correct diagnosis outside endemic areas and provides an overview of typical clinical, neuropathological and neuroimaging findings in T. b. gambiense trypanosomiasis, guiding the clinician in establishing the correct diagnosis in this rare disease.

    Aim. To study the evolution of impaired fasting glucose (IFG), considering glucose and HbA1c levels and risk factors associated, in a period of 6 years. Methods. We studied 94 subjects with impaired fasting glucose (IFG) that were diagnosed in 2005 and followed up to 2012. Glucose and HbA1c levels were determined. A descriptive analysis of contingence charts was performed in order to study the evolution in the development of type-2 diabetes mellitus (T2DM). Results. Twenty-eight of ninety-four subjects became T2DM; 51/94 remained with IFG; and 20/94 presented normal fasting glucose. From the 28 diabetic subjects, 9 had already developed diabetes and were under treatment with oral hypoglycemic agents; 5 were diagnosed with plasma glucose < 126 mg/dL, but with HbA1c over 6.5%. In those who developed diabetes, 15/28 had a family history of T2DM in first relative degree. Also, diabetic subjects had a BMI significantly higher than nodiabetics (t test: P < 0.01). The individuals that in 2005 had the highest BMI are those who currently have diabetes. Conclusion. The IFG constitutes a condition of high risk of developing T2DM in a few years, especially over 110 mg/dL and in obesity patients. PMID:25215305

    This study investigates the sources of fine particulate matter (aerodynamic diameter ≤2.5 μm; PM(2.5)) composition for the Baltimore, Maryland, metropolitan area, covering a 6-year period (2008-2013). Data obtained from the U.S. Environmental Protection Agency (EPA) Air Quality System (AQS) were used for the identification of eight chemical speciation clusters (factors), which, as a percentage of the average concentration, were identified as secondary sulfate (31.9%), secondary nitrate (14.3%), gasoline (17.4%), diesel (10.1%), soil (4.0%), biomass burning (11%), marine aerosol (4.1%), and industrial processing (7.2%). The results show predominant influence from vehicle emissions transiting major highways I-695 and I-95 located in the vicinity of the sampling site. Strong influence on PM2.5 mass from biomass burning was found in the first 2 years (2008-2009) due to particulate matter remnants from forest fire events in North Carolina and a strong contribution in 2013 that was due mainly to wood burning during winter. Sulfate, nitrate, soil, and marine aerosol fractions registered very low variability over the 6-year period analyzed. In addition, this study shows a significant reduction in particulate matter from industrial origins after a major industrial source in Baltimore shut down. The results obtained from Baltimore were compared with those from the Beltsville, Maryland, sampling station located 25 miles south of Baltimore for 2011 and 2012, where good agreement was found for most of the factors. This paper presents the first long-term aerosol speciation analysis in a Mid-Atlantic United States metropolitan area, which is essential for the air quality management agencies in order to revise regulations and reduce human exposure to adverse air quality conditions. The results suggest that although a declining trend in the overall PM2.5 was observed, no significant tendency was observed in the identified sources besides exceptional events such as the impact of

    Land Surface Phenology (LSP) is the most direct representation of intra-annual dynamics of vegetated land surfaces as observed from satellite observations. As such, LSP plays a key role in understanding the terrestrial carbon budget, as well as the response of terrestrial ecosystems to environmental change. Various studies have highlighted significant increases in vegetation activity over time (i.e. greening) over Europe in recent decades (e.g. Stöckli and Vidale, 2004), associated both with climatic changes and with large-scale human interventions including land-use change (de Jong et al., 2013). In this study, we characterize LSP changes in Europe's eco-regions for the last 30 years. We used the latest version of the 8-km Global Inventory Modeling and Mapping Studies (GIMMS) Normalized Difference Vegetation Index dataset (third generation, or NDVI-3g) to retrieve LSP metrics for Europe for the last three decades (1982-2011). Each year of NDVI data was processed using the Harmonic Analysis of Time Series (HANTS) algorithm, producing smooth NDVI annual profiles on a pixel-by-pixel basis. In order to derive LSP metrics for each year, namely Start, End and Length of Growing Season, we selected the Midpoint-pixel local threshold method, based on the White et al. (2009) inter-comparison. A landscape-based stratification, using the European Landscape Classification (LANMAP) (Mücher et al., 2010) allowed us to examine LSP characteristics and trends for the different European eco-regions. We demonstrate significant shifts in LSP metrics over the study period, with a general lengthening of the growing season in Europe of approximately 0.4 days year-1. LSP trends varied significantly between eco-regions, and we discuss potential reasons for these spatially diverse trends. de Jong, R., et al.

    Full Text Available Abstract Objectives to evaluate mother-to-child transmission (MTCT rates and related factors in HIV-infected pregnant women from a tertiary hospital between 2000 and 2009. Subjects and method cohort of 452 HIV-infected pregnant women and their newborns. Data was collected from recorded files and undiagnosed children were enrolled for investigation. Statistical analysis: qui-square test, Fisher exact test, Student t test, Mann-Whitney test, ANOVA, risk ratio and confidence intervals. Results MTCT occurred in 3.74%. The study population displayed a mean age of 27 years; 86.5% were found to have acquired HIV through sexual contact; 55% were aware of the diagnosis prior to the pregnancy; 62% were not using HAART. Mean CD4 cell-count was 474 cells/ml and 70.3% had undetectable viral loads in the third trimester. HAART included nevirapine in 35% of cases and protease inhibitors in 55%; Zidovudine monotherapy was used in 7.3%. Mean gestational age at delivery was 37.2 weeks and in 92% by caesarian section; 97.2% received intravenous zidovudine. Use of AZT to newborn occurred in 100% of them. Factors identified as associated to MTCT were: low CD4 cell counts, elevated viral loads, maternal AIDS, shorter periods receiving HAART, other conditions (anemia, IUGR (intra uterine growth restriction, oligohydramnium, coinfecctions (CMV and toxoplasmosis and the occurrence of labor. Use of HAART for longer periods, caesarian and oral zidovudine for the newborns were associated with a decreased risk. Poor adhesion to treatment was present in 13 of the 15 cases of transmission; in 7, coinfecctions were diagnosed (CMV and toxoplasmosis. Conclusion Use of HAART and caesarian delivery are protective factors for mother-to-child transmission of HIV. Maternal coinfecctions and other conditions were risk factors for MTCT.

    To identify the types of studies of nursing taxonomies and priority research themes presented at AENTDE conferences between 1996 and 2012. Four hundred oral communications and posters and 27 lectures presented at the AENTDE meetings were reviewed by means of a descriptive analysis of the types of studies conducted and a content analysis of priority research themes. The most commonly presented studies were descriptions of the implementation of nursing taxonomies, which accounted for 27.4% of the total over the 16-year period. However, their prevalence fell from 31.8% in 1996 to 9.1% in 2012. Basic research studies accounted for 17.4% of studies overall but were the most frequent in 2012, when their proportion had risen to 37.5%. The prevalence of basic research studies increased notably over the 16-year period. Content validity studies rose in number, while face validity studies fell. Studies of the practical implementation of taxonomies also declined.

    Full Text Available Candidemia is an important emerging nosocomial infection in patients with risk factors. Candida species from nonsterile sites can give insight into the characteristics of strains that may cause invasive disease. The aim of this study was to evaluate antifungal susceptibility of Candida blood and fecal isolates in Novi Sad, Vojvodina. During a 3-year period (2008 to 2010, 424 isolates of Candida spp. were collected, 30 bloodstream isolates and 394 strains from fecal samples. In vitro susceptibility of these isolates to five antifungal agents was established using commercial ATB FUNGUS 3 (Bio-Mérieux. Predominant species was Candida albicans (6 isolates from blood and 269 from feces. Resistance to one or more antifungal agents was less common in Candida albicans (3.63% than in other species (24.83%. Resistance to itraconazole was the most commonly found in both groups of isolates, 9.64% strains from feces and 20% from blood samples. Twelve isolates were multiply resistant, usually to fluconazole, itraconazole, and voriconazole. Resistance to amphotericine B was extremely rare. Although resistance to antimycotics of Candida spp. is rare at present, continued surveillance of antifungal susceptibility is necessary in order to monitor trends, and to choose the right empiric therapy.

To determine the presence of CVRFs and their changes in different health care professionals over a period of 20 years. All students of medicine, nursing, nutrition, odontology, and pharmacy departments of Federal University of Goiás who agreed to participate in this study were evaluated when they started their degree courses and 20 years afterward. Questionnaires on CVRFs [systemic arterial hypertension (SAH), diabetes mellitus, dyslipidemia, and family history of early CVD, smoking, alcohol consumption, and sedentarism] were administered. Cholesterol levels, blood sugar levels, blood pressure, weight, height, and body mass index were determined. The Kolmogorov-Smirnov test was used to evaluate distribution, the chi-square test was used to compare different courses and sexes, and the McNemar test was used for comparing CVRFs. The significance level was set at a p value of < 0.05. The first stage of the study included 281 individuals (91% of all the students), of which 62.9% were women; the mean age was 19.7 years. In the second stage, 215 subjects were reassessed (76% of the initial sample), of which 59.07% were women; the mean age was 39.8 years. The sample mostly consisted of medical students (with a predominance of men), followed by nursing, nutrition, and pharmacy students, with a predominance of women (p < 0.05). Excessive weight gain, SAH, and dyslipidemia were observed among physicians and dentists (p < 0.05). Excessive weight gain and SAH and a reduction in sedentarism (p < 0.05) were observed among pharmacists. Among nurses there was an increase in excessive weight and alcohol consumption (p < 0.05). Finally, nutritionists showed an increase in dyslipidemia (p < 0.05). In general, there was an unfavorable progression of CVRFs in the

    Full Text Available The effect of global climate change on the annual average concentration of fine particulate matter (PM2.5 in California was studied using a climate-air quality modeling system composed of global through regional models. Output from the NCAR/DOE Parallel Climate Model (PCM generated under the "business as usual" global emissions scenario was downscaled using the Weather Research and Forecasting (WRF model followed by air quality simulations using the UCD/CIT airshed model. The system represents major atmospheric processes acting on gas and particle phase species including meteorological effects on emissions, advection, dispersion, chemical reaction rates, gas-particle conversion, and dry/wet deposition. The air quality simulations were carried out for the entire state of California with a resolution of 8-km for the years 2000–2006 (present climate with present emissions and 2047–2053 (future climate with present emissions. Each of these 7-year analysis periods was analyzed using a total of 1008 simulated days to span a climatologically relevant time period with a practical computational burden. The 7-year windows were chosen to properly account for annual variability with the added benefit that the air quality predictions under the present climate could be compared to actual measurements. The climate-air quality modeling system successfully predicted the spatial pattern of present climate PM2.5 concentrations in California but the absolute magnitude of the annual average PM2.5 concentrations were under-predicted by ~4–39% in the major air basins. The majority of this under-prediction was caused by excess ventilation predicted by PCM-WRF that should be present to the same degree in the current and future time periods so that the net bias introduced into the comparison is minimized.

    The study evaluated the changes in the prevalence of Helicobacter pylori strains with primary resistance to antibiotics during the last 10 years in Lithuania. H. pylori susceptibilities to antibiotics were tested in 89 patients in 1998, in 81 patients in 2001 and in 90 patients in 2007/2008. Susceptibility to metronidazole, clarithromycin, amoxicillin and tetracycline was tested using E-test or agar dilution method. Susceptibility to ciprofloxacin was only tested in 2007/2008. Data about utilization of all authorized and available on market macrolides and clindamycin in Lithuania during 2003-2007 were evaluated using WHO ATC/DDD methodology. A total of 260 H. pylori strains cultured from untreated adult patients were investigated. Primary resistance rates (1998, 2001 and 2007/2008) for metronidazole were 24.7%, 33.3%, and 35.6%, for clarithromycin 1.1%, 3.7%, and 3.3% and for tetracycline 0%, 2.5% and 0% respectively. No cases of amoxicillin resistance have been detected. The resistance rate for ciprofloxacin was 5.6% in 2007/2008. Data of total macrolides and clarithromycin utilization in Lithuania revealed that despite an increase of consumption of these drugs in Lithuania during 2003-2007 in 1.5 times, the total macrolide consumption remains one of the lowest in Europe. We have not observed any significant changes in the susceptibility of H. pylori to the most widely used antibiotics during the recent 10-year period. The low resistance rate to clarithromycin might be related to the policy to avoid use of macrolides as first-line treatment for pulmonary and other infections.

    Full Text Available Persistent pulmonary hypertension of the newborn (PPHN is a condition in which the pulmonary vessels fail to dilate at birth. It can be the consequence of a wide array of diseases, such as pneumonia, congenital diaphragmatic hernia, meconium aspiration syndrome and hyaline membrane disease. It has an incidence of 1-2 per 1,000 newborns and it can have pulmonary, neurologic and developmental consequences. We conducted a retrospective study with the aim of analyzing the causes, morbidities and comorbidities, management and mortality of PPHN in newborns hospitalized in our neonatal intensive care unit (NICU and to evaluate respiratory, neurologic and developmental morbidity at 2 years of age. A total of 77 children, born between 1996 and 2012, were studied. Twenty-six (33.8% deceased. The mortality, as well as the need for resuscitation, inhaled nitric oxide (iNO, diuretics, and vasopressor support, was higher in patients with the severe form of PPHN. The need for vasopressor support was the only factor associated with a higher mortality. We found a reduction of 17.8% in mortality rates after the introduction of iNO, sildenafil and extracorporeal membrane oxygenation (ECMO. Congenital diaphragmatic hernia was the most common cause of PPHN. Pneumonia was more frequent before 2003. There was no significant difference in the morbidity and mortality between the two time periods (before and after 2003. On the follow-up of 37 of the remaining 51 patients, we did not find differences in the morbidity of patients comparing those with the severe vs. non-severe forms of the condition.An evaluation over the years of admitted newborns with PPHN in our NICU is mandatory to confirm a relationship between the new treatment strategies and the better outcome of the patients.

    Halitosis or bad breath is a taboo subject that is a widespread problem in the general population. Causes of bad breath can be multifactorial and long time sufferers can be marred from deep psychological stress. Because nine out of ten cases have an oral cause, the initial inquiry should be with a dentist. In a retrospective study from February 2003 to February 2010, the halitosis clinic at the University of Basel analyzed data from 465 patient medical histories. Study objectives evaluated the causes of halitosis, gender distribution and treatment success. All patients reported to have suffered from bad breath. However, 82.7% were actually diagnosed as having halitosis. Within this group, 96.2% showed an oral etiology and 3.8% showed an extra-oral cause. Women suffered significantly more from psychogenic halitosis. Success rates of 92.6% subjectively and 94.5% objectively reflect the treatment success of the diagnostic and therapeutic concepts presented at the University of Basel halitosis clinic over a seven year period.

    This study was taken up with the aim to investigate the pattern of supraclavicular lymphadenopathy among patients presenting to our tertiary care institution, evaluate the diagnostic efficacy of fine needle aspiration cytology (FNAC), and analyze the diagnostic pitfalls. A total of 215 patients were subjected to FNAC of supraclavicular lymph nodes over a three-year period (August 2006 to July 2009). Since in 18 patients as either the aspirate was inadequate or the opinion was equivocal, we analyzed the remaining 197 cases. Malignant pathology accounted for 79.7% (157/197) of the cases. These were mostly cases of metastatic squamous cell carcinoma (79/197, 40.1%), adenocarcinoma (47/197, 23.9%), small cell carcinoma (12/197, 6.1%) and lymphoma (10/197, 5%). There were 28 (14.2%) cases of tuberculosis. Out of these 197 patients, 92 patients were biopsied. The opinion based on FNAC was erroneous in 6 cases but corroborated with the final histopathology findings in the remaining 86 cases. FNAC is an excellent first line of investigation; and when used with a proper combination of experience and diligence, it can greatly reduce the number of errors.

    Full Text Available Advertising that has become an indispensable element of today’s conditions has also become a frequently used tool of goods and services the companies utilized. With the advances in technology, the number of companies that commercialises their goods has been steadily increasing day by day. That fact that advertising has become such a significant sector of the industry; has provided this sector with the opportunity to contact a lot of people all at the same time. That is why; advertising is special among the marketing and the media tools. The Tanin newspaper discussed in this article began to be broadcast towards the end of the Ottoman Empire. The newspaper that began to be published in the late Ottoman and the early Turkish Republic eras came to the fore as a political organ rather than the advertisements of the publication. The number of Tanin newspaper published during the years 1908-1909 were examined in this article. The newspaper had published many advertisements and covered many brands in the issues that were published during this period,The newspaper that encountered various obstacles during its life of publication bears importance by being, established by the Committee of Union and Progress members as well

    Full Text Available The aim of the study is to present the results of a 3-year clinico-epidemiological investigation of caustic injury in adults. The study includes 43 patients with acute corrosive ingestion, hospitalized in the Toxicology Clinic, University Hospital “N. I. Pirogov”, Sofia, Bulgaria, for the period 01.01. 2010-31.12.2012. The methods used include: clinical observation and examination, clinical laboratory, imaging, and psychiatric methods and tests. 43 patients between the ages of 22 and 82 with acute corrosive ingestions have been observed. Eleven were male (25.6% and 32 female (74.4%. All ingestions were intentional. Alkaline agents were used by all of the patients. The severity of poisonings varied from moderate to extremely severe. Different complications were seen in 82% of the cases - severe bleeding, perforation, fistula or/and stricture formation. Two of the patients have undergone surgical intervention - coloesophagoplastic - and have recovered completely. The motivation in different age groups was also studied. Psychiatric comorbidity occurred in patients as depressive and schizoaffective disorder, as well as existential crises. Acute corrosive ingestions by alkaline agents cause severe pathology. The severity and complex character of the injuries require good coordination between different medical specialists.

    Among the immediate transfusion reactions caused by the utilization of blood products, those suggesting immuno-allergic mechanisms posed problems for frequency, gravity, laboratory diagnosis and safety. We report here the Lille Hospital's experience over a four-year period concerning these manifestations after platelet concentrate transfusion. Eight hundred and fifty-two immediate transfusion reactions have been declared, of which 230 were allergic, which appeared in 181 patients (27%). Among the most frequent clinical signs, rash was often described (158 cases: 68.7%); less frequent were respiratory problems such as dyspnea (34 cases: 14.8%) and hypotensive reactions (18 cases: 7.8%). Seven patients presented severe reactions (3%). Twenty percent of them presented multiple allergic reactions and in 43.2%, the recurrence was more serious than the initial problem in spite of preventive medication; the use of washed blood components was necessary. The age of platelet concentrates does not appear to play a part in provoking these events (67% of platelet concentrates had been collected within four days). These allergic transfusion reactions posed problems for those who prescribe medication, because they are frequent, sometimes serious, can recur and at present, the proposed medication prevention is not always efficient.

  17. 1,500 Year Periodicity in Central Texas Moisture Source Variability Reconstructed from Speleothems

    Delineating the climate processes governing precipitation variability in drought-prone Texas is critical for predicting and mitigating climate change effects, and requires the reconstruction of past climate beyond the instrumental record. Presently, there are few high-resolution Holocene climate records for this region, which limits the assessment of precipitation variability during a relatively stable climatic interval that comprises the closest analogue to the modern climate state. To address this, we present speleothem growth rate and δ18O records from two central Texas caves that span the mid to late Holocene, and assess hypotheses about the climate processes that can account for similarity in the timing and periodicity of variability with other regional and global records. A key finding is the independent variation of speleothem growth rate and δ18O values, suggesting the decoupling of moisture amount and source. This decoupling likely occurs because i) the often direct relation between speleothem growth rate and moisture availability is complicated by changes in the overlying ecosystem that affect subsurface CO2 production, and ii) speleothem δ18O variations reflect changes in moisture source (i.e., proportion of Pacific- vs. Gulf of Mexico-derived moisture) that appear not to be linked to moisture amount. Furthermore, we document a 1,500-year periodicity in δ18O values that is consistent with variability in the percent of hematite-stained grains in North Atlantic sediments, North Pacific SSTs, and El Nino events preserved in an Ecuadorian lake. Previous modeling experiments and analysis of observational data delineate the coupled atmospheric-ocean processes that can account for the coincidence of such variability in climate archives across the northern hemisphere. Reduction of the thermohaline circulation results in North Atlantic cooling, which translates to cooler North Pacific SSTs. The resulting reduction of the meridional SST gradient in the Pacific

    Danish battlefield surgery in the period between the birth of Christ and the year 500 AD is exemplified by a reinterpretation of artefacts found in the sacrificial bogs at Thorsbjerg, Nydam, Ejsbøl, Illerup Adal, Vimose and Kragehul, reinterpreted in the light of classic European and Egyptian archaeological finds and ethno-archaeological parallels against the background of the author's years of experience as a practicing specialist in gynaecology and obstetrics. No surgical instruments from the Iron Age have previously been construed or identified as such in Denmark or Schleswig-Holstein. The purpose of this paper is to examine the possible finding and identificiation of surgical instruments - or what could be construed as a battlefield surgeons instruments - among artefacts deposited in the above-mentioned sacrificial bogs in the Iron Age. In this paper, the term 'surgical instrument' is defined as an instrument used in teh practice of medicine. Material for the study was collected in a review of illustrations in published works about these bog finds, localising these artefacts and examining them at the museums at which they were located. Also examined was museum storage of artefacts that had been excavated in the above-mentioned bogs. In an effort to reinterpret the function of the artefacts, they were compared with known surgical instruments found in the geographical areas controlled by the Greeks and later the Romans and with pictures of artefacts and a few written sources form the same area. They were also compared with ethnographic parallels. The material upon which the paper is based consists of a total of 67 artefacts, each identified as being from one of the above-mentioned bogs. Of these 67 artefacts, 40 can be indentifed and reinterpreted as being surgical instruments and 27 are toilet sets, i.e. tweezers for personal use or sets consisting of tweezers connected by a metal ring to either an ear pick or a nail cutter. Analysis of the artefacts revealed

  2. Targets and Patented Drugs for Chemotherapy of Chagas Disease in the Last 15 Years-Period.

    The American trypanosomiasis, Chagas disease, is a parasitic infection typically spread by triatomine vectors affecting millions of people all over Latin America. Existing chemotherapy is centered on the nitroaromatic compounds benznidazole and nifurtimox that provide unsatisfactory results and substantial side effects. So, the finding and exploration of novel ways to challenge this neglected disease is a main priority. The biologic and biochemical progress in the scientific knowledge of Trypanosoma cruzi in the period comprising last 15-years has increased the identification of multiple targets for Chagas´ disease chemotherapy. In the middle of the best encouraging targets for trypanocidal drugs, ergosterol biosynthesis pathway and cruzipain, a key cysteine protease (CP) of T. cruzi, have been pointed out. Unfortunately, recent clinical trials investigating the administration of pozoconazole and ravuconazole to chronic indeterminate Chagas disease patients revealed their inferiority compared to the standard drug Benznidazole. In view of the information gained in the preceding years, a reasonable approach for the fast development of novel anti-T. cruzi chemotherapy would be focused on K777, the cysteine proteinase inhibitor (CPI) near to enter to clinical trials, and founded on the clinical evaluation of combination of known drugs with existing trypanocidal agents to obtain more efficiency and less secondary effects. Top series of xanthine have been recently identified as clinical candidate for Chagas disease. In addition, trypanothione biosynthesis, thiol-dependant redox and polyamine metabolism, the glycolytic, glyconeogenic, pentose phosphate, lipidic and polyisoprenoid biosynthetic pathways, and the enzymes from biosynthetic glycoconjugates pathways have been studied. Several specific enzymes from these particular biosynthetic pathways such as hypoxanthine-guaninephosphoribosyl- transferase and farnesyl-pyrophosphate synthase, among others, have also been

    The use of email can facilitate communication between the different levels of an organisation. Our primary care physicians have had an email service in the dedicated headache clinic (DHC) since November 2009, and our aim is therefore to analyse the use of email over that five-year period. Data concerning the emails sent up until October 2014 were collected prospectively. The questions were classified as need for referral to the DHC (group 1), progress made by the cases seen in the DHC (group 2), training in headaches (group 3) or the treatment of the headaches suffered by primary care physicians themselves as patients (group 4). A total of 274 email messages were analysed. Monthly consultations have increased (from 1.5 per month during the first year to 7.5 per month during the fifth). Findings showed that 10.2% of the email messages came from rural health centres and 89.8% were sent from urban health centres. Replies were sent within 2 ± 2.8 days (range: 0-24 days). Altogether 130 consultations were classified as belonging to group 1 (47.4%), in which referral through the normal channel was recommended in 60 cases (46.2%), via the preferential channel in 47 (36.2%) and non-referral was suggested in 23 cases (17.6%). Group 2 included 125 emails (45.7%) and in 80 cases there was no need to make a new appointment or to bring forward the existing one (64%). Thirteen visits (4.7%) were classified into group 3 and six (2.2%) in group 4. Our primary care physicians are using the email of the DHC on an increasingly more frequent basis. Its use makes it possible to detect patients whose appointment -whether the first or a follow-up- needs to be brought forward, as well as allowing issues to be solved without the need for referral. It is effective for the treatment of physicians who themselves have headaches and as a tool for continuing education.

    The Dothideomycetes are one of the largest and most diverse groups of fungi. Many are plant pathogens and pose a serious threat to agricultural crops grown for biofuel, food or feed. Most Dothideomycetes have only a single host and related Dothideomycete species can have very diverse host plants. Twelve Dothideomycete genomes have currently been sequenced by the Joint Genome Institute and other sequencing centers. They can be accessed via Mycocosm which has tools for comparative analysis

  5. The evolutionary and genetic origins of consciousness in the Cambrian Period over 500 million years ago

    Vertebrates evolved in the Cambrian Period before 520 million years ago, but we do not know when or how consciousness arose in the history of the vertebrate brain. Here we propose multiple levels of isomorphic or somatotopic neural representations as an objective marker for sensory consciousness. All extant vertebrates have these, so we deduce that consciousness extends back to the group's origin. The first conscious sense may have been vision. Then vision, coupled with additional sensory systems derived from ectodermal placodes and neural crest, transformed primitive reflexive systems into image forming brains that map and perceive the external world and the body's interior. We posit that the minimum requirement for sensory consciousness and qualia is a brain including a forebrain (but not necessarily a developed cerebral cortex/pallium), midbrain, and hindbrain. This brain must also have (1) hierarchical systems of intercommunicating, isomorphically organized, processing nuclei that extensively integrate the different senses into representations that emerge in upper levels of the neural hierarchy; and (2) a widespread reticular formation that integrates the sensory inputs and contributes to attention, awareness, and neural synchronization. We propose a two-step evolutionary history, in which the optic tectum was the original center of multi-sensory conscious perception (as in fish and amphibians: step 1), followed by a gradual shift of this center to the dorsal pallium or its cerebral cortex (in mammals, reptiles, birds: step 2). We address objections to the hypothesis and call for more studies of fish and amphibians. In our view, the lamprey has all the neural requisites and is likely the simplest extant vertebrate with sensory consciousness and qualia. Genes that pattern the proposed elements of consciousness (isomorphism, neural crest, placodes) have been identified in all vertebrates. Thus, consciousness is in the genes, some of which are already known. PMID

    Full Text Available Background: Schizophrenia has been identified as one of the most disabling condition known to mankind. Until recently there was no published literature on disability certification seeking behavior of patients diagnosed with schizophrenia. The current study aimed at understanding the profile of patients diagnosed with schizophrenia seeking disability certification for a tertiary level multispecialty hospital in India. Materials a nd Methods: The study was carried out at the Psychiatry department for a tertiary care hospital in India. The evaluation of the subjects was carried out in the presence of a primary care giver. First, the diagnosis was established using International Statistical Classification of Diseases and Related Health Conditions (ICD-10. Subsequently, the disability was assessed using Indian Disability Evaluation Assessment Scale (IDEAS. Data were analyzed using SPSS (Statistical Package for Social Sciences software version 17. Results: A total of 169 subjects seeking disability certification over the study period of 5 years were diagnosed with schizophrenia. Out of 169 subjects 132 (78.1% were male and 37 (21.9% were female. There was a statistically significant difference in the marital status of the male and female study subjects. Family history of psychiatric illness was positive in 9.8% of male subjects and 10.8% of female subjects. There was no significant difference between male and female subjects for the duration of illness and duration of being on treatment. Male and female subjects did not differ significantly on the IDEAS global score, personal care, interpersonal interaction, and understanding and communication domains of IDEAS. The two groups differed significantly on the work domain. Conclusions: Majority of patients with schizophrenia seeking disability certificate continue to be male. However, male and female subjects tend to differ very little on various socio-demographic and illness related variables. The levels

    Radiation fog samples have been collected at a rural site in Central Pennsylvania from 2007 through 2015 in order to document chemical composition, assess concentration changes over time, and to provide insight into emission sources that influence the region. The collection of samples over multiple years makes this one of the few long duration radiation fog studies that have been completed. During the course of the campaign, 146 samples were obtained and analyzed for pH, major inorganic ions, low molecular weight organic acids, total organic carbon (TOC) and total nitrogen (TN). Ammonium (median concentration = 209 μN), sulfate (69 μN), calcium (51 μN), and nitrate (31 μN) were the most abundant inorganic ions, although these were present at much lower concentrations than for radiation fog studies conducted in other locations. Organic acids, of which formate (20 μM) and acetate (21 μM) were the most abundant, were closer in magnitude to measurements made during previous studies. Organic acids accounted for 15% of TOC, which had a median concentration of 6.6 mgC l-1. The median concentration of TN was 3.6 mgN l-1, 18% of which was determined to be organic nitrogen. Statistically significant decreasing trends from 2007 to 2015 were noted for sulfate, ammonium, chloride, and nitrate. For the same period, an increase in pH was observed. Seasonal trends were identified for a number of species as well. The partitioning of ammonia between the gas and aqueous phases was also investigated and found to deviate significantly from equilibrium.

    The prevalence of child maltreatment in the Netherlands was in 2005 first systematically examined in the Netherlands' Prevalence study on Maltreatment of children and youth (NPM-2005), using sentinel reports and substantiated CPS cases, and in the Pupils on Abuse study (PoA-2005), using high school students' self-report. In this second National Prevalence study on Maltreatment (NPM-2010), we used the same three methods to examine the prevalence of child maltreatment in 2010, enabling a cross-time comparison of the prevalence of child maltreatment in the Netherlands. First, 1,127 professionals from various occupational branches (sentinels) reported each child for whom they suspected child maltreatment during a period of three months. Second, we included 22,661 substantiated cases reported in 2010 to the Dutch Child Protective Services. Third, 1,920 high school students aged 12-17 years filled out a questionnaire on their experiences of maltreatment in 2010. The overall prevalence of child maltreatment in the Netherlands in 2010 was 33.8 per 1,000 children based on the combined sentinel and CPS reports and 99.4 per 1,000 adolescents based on self-report. Major risk factors for child maltreatment were parental low education, immigrant status, unemployment, and single parenthood. We found a large increase in CPS-reports, whereas prevalence rates based on sentinel and self-report did not change between 2005 and 2010. Based on these findings a likely conclusion is that the actual number of maltreated children has not increased from 2005 to 2010, but that professionals have become more aware of child maltreatment, and more likely to report cases to CPS.

    Full Text Available Abstract Background Head lice infestation is an infection of the scalp and skin which causes blood loss, discomfort, and social and psychological distress with the possibility of secondary bacterial infections occurring at scratch sites. In Pakistan, although some small scale studies have been conducted to investigate prevalence of head lice in school children and the general population, no population based estimates have been reported. The National Health Survey of Pakistan (NHSP 1990 - 94 was a nationally representative health examination survey of the Pakistani population. The NHSP is the first population based household survey to collect data on the prevalence of head lice in adult women in Pakistan. In this paper we use data from the NHSP to present an epidemiological profile of personal hygiene practices and head lice infestation among women aged 12 years or older in three provinces of Pakistan; Balochistan, Sindh and North West Frontier Province (NWFP. Results Overall about 7% women aged 12 years and older suffered from head lice infestation. Multivariable logistic regression analysis identified factors independently associated with presence of head lice. Age less than 16 years and crowding at home were associated with higher infestation-rates. The impact of household socio-economic status on infestation rates among women was different in urban and rural settings; urban women with low socio-economic status were more vulnerable than similar women in rural settings. Bathing infrequently in summer was associated with higher prevalence rates only in Sindh, possibly due to the fact that among the three provinces Sindh has a hotter and more humid summer. Conclusions The results of our analysis of NHSP indicate high levels of head lice infestation among girls and women in the three Provinces. The epidemiological profile of hygienic practices of women indicated that NWFP and Balochistan as compared to Sindh, and rural as compared to urban areas

    We analyzed Sardinian registry data to assess time trends in incidence rates (IRs) of type 1 diabetes during the period 1989-2009 (2,371 case subjects 0-14 years of age). Poisson regression models were used to estimate the effects of sex, age, period of diagnosis, and birth cohorts. IR was 44.8 cases/100,000 person-years (95% CI 43.1-46.7). The annual increase was 2.12% (1.45-2.80; test for linear trend, P 1). For boys, the increasing trend was evident up to 5 years of age and for girls up to 8 years of age. Compared with the 1989-1994 birth cohort, the relative risk increased from 0.78 (0.61-1.10) in 1974-1979 to 1.62 (1.18-2.23) in 2004-2009. The increase over period was less striking, with a tendency to regress in more recent years. The best-fitting model for boys included age and a linear time trend, and for girls age and nonlinear effects of calendar period and birth cohort. In conclusion, incidence increased over time, and the increase tended to level off in more recent years by calendar period but not by birth cohort, with some evidence of a stronger increase among girls than boys. Should the increase be attributable to the effects of some perinatal environmental factor, this would mean that such a factor has started affecting females before males.

    DISCOVERY: A periodicity of 500 years has been discovered in the political history of ancient Egypt and documented by means of inferential statistics. Periods of chaos and waning of central power (some of them called "intermediate periods") recurred every 500 years. Input for the computation is the mean duration of ruling dynasties calculated per each half century. Fisher's periodogram analysis and Halberg's cosinor regression have been used. A highly significant (p system of man by raising the levels of androgens periodically. EXPLANATION HYPOTHESES: Sun impacts global weather on Earth, but there is no known significant periodicity of 500 years in solar activity. The Wheeler weather cycle almost fits the cycle of Egyptian political history. But his cold-dry periods seem to lag behind the periods of social destabilization and hence can not cause them. An alternative view (based on idealistic rather than materialistic presuppositions) is, that periodic long-term shifts of archetypes take place within the collective unconscious of mankind independently of external environment.

    We analyzed Sardinian registry data to assess time trends in incidence rates (IRs) of type 1 diabetes during the period 1989–2009 (2,371 case subjects 0–14 years of age). Poisson regression models were used to estimate the effects of sex, age, period of diagnosis, and birth cohorts. IR was 44.8 cases/100,000 person-years (95% CI 43.1–46.7). The annual increase was 2.12% (1.45–2.80; test for linear trend, P < 0.001). For boys, the increasing trend was evident up to 5 years of age and for girls...

  17. A simple stochastic model with environmental transmission explains multi-year periodicity in outbreaks of avian flu.

    Full Text Available Avian influenza virus reveals persistent and recurrent outbreaks in North American wild waterfowl, and exhibits major outbreaks at 2-8 years intervals in duck populations. The standard susceptible-infected- recovered (SIR framework, which includes seasonal migration and reproduction, but lacks environmental transmission, is unable to reproduce the multi-periodic patterns of avian influenza epidemics. In this paper, we argue that a fully stochastic theory based on environmental transmission provides a simple, plausible explanation for the phenomenon of multi-year periodic outbreaks of avian flu. Our theory predicts complex fluctuations with a dominant period of 2 to 8 years which essentially depends on the intensity of environmental transmission. A wavelet analysis of the observed data supports this prediction. Furthermore, using master equations and van Kampen system-size expansion techniques, we provide an analytical expression for the spectrum of stochastic fluctuations, revealing how the outbreak period varies with the environmental transmission.

    Full Text Available Introduction. Chronic kidney disease (CKD is a significant cause of morbidity and mortality in paediatric population. Objective. The aim of the study was analysis of aetiology, staging and associated complications of CKD at the time of diagnosis. Methods. Data of 97 patients (56 boys of average age 7.8±5.8 years, referred for the first time to the Institute for Mother and Child Healthcare „Dr Vukan Čupić”, Belgrade in the period 1998- 2009, due to CKD, stage 2-5, were analysed. In each patient illness history was obtained, and physical examination, laboratory, X-ray and other investigations were performed according to the indications. CKD was classified according to the glomerular filtration rate into four grades: 2 - mild (60-90 ml/min/1.73 m2; 3 - moderate (30-60 ml/min/1.73 m2; 4 - advanced (15-30 ml/ min/1.73 m2; and 5 - terminal (<15 ml/min/1.73 m2. Results. The most frequent causes of CKD were congenital anomalies of the kidney and urinary tract (43.3%, followed by glomerular diseases (17.5%, hereditary kidney diseases (16.5%, metabolic diseases (7.2% and other causes (15.5%. Mild CKD was found in 29.8%, moderate in 28.9%, advanced in 22.7%, and terminal in 18.6% children. Among patients with CKD stage 4 and 5, 75% of patients presented with acute renal failure, while 25% had earlier detected CKD (stage 1, but were not under regular follow-up. Associated complications included metabolic acidosis (63%, anaemia (60%, hypertension (42.3%, short stature (25.8%, renal osteodystrophy (13.4% and cardiovascular diseases (7.2%. Conclusion. Congenital anomalies of the kidney and urinary tract are the leading cause of CKD in paediatric population. A significant proportion (41.3% of patients had advanced and terminal CKD. In most patients CKD was diagnosed late and with associated complications.

    Variability in reporting and classification methods in previous published data of the final dispositions in the rehabilitation of wild raptors makes use of this data limited in trying to audit the quality of the rehabilitation process. Crude as well as stratified disposition rates are needed if quality auditing of the rehabilitation process is to be adequately performed. Final dispositions of 6221 hospitalized wild raptors admitted at a wildlife rehabilitation centre (WRC) of Catalonia during 1995-2007 were analyzed. These dispositions were calculated as the euthanasia (Er), unassisted mortality (Mr), release (Rr) and captivity rates (Cr)., time to death (Td) for dead and euthanized raptors, and length of stay for released (Tr) raptors was estimated. Stratified analyses by main causes of admission and clinical signs were performed. THE DISPOSITION FOR THE TOTAL POPULATION WERE: Er = 30.6%, Mr = 19.1%, Rr = 47.2%, and Cr = 3%. By main causes of admission, Er was higher in the trauma category (34.2%), whereas Mr was found similar between trauma (37.4%) and non-trauma categories (34.8%). The highest Rr was observed for the orphaned group (77.9%). Furthermore, Cr was low in all the categories (rehabilitation should include the crude and stratified rates (Er, Mr, Rr, and Cr), by causes and clinical presentation, as well as Td and Tr, to allow meaningful auditing of the rehabilitation process quality.

  4. Periodic Impact Cratering and Extinction Events Over the Last 260 Million Years

    2015-01-01

    The claims of periodicity in impact cratering and biological extinction events are controversial. Anewly revised record of dated impact craters has been analyzed for periodicity, and compared with the record of extinctions over the past 260 Myr. A digital circular spectral analysis of 37 crater ages (ranging in age from 15 to 254 Myr ago) yielded evidence for a significant 25.8 +/- 0.6 Myr cycle. Using the same method, we found a significant 27.0 +/- 0.7 Myr cycle in the dates of the eight recognized marine extinction events over the same period. The cycles detected in impacts and extinctions have a similar phase. The impact crater dataset shows 11 apparent peaks in the last 260 Myr, at least 5 of which correlate closely with significant extinction peaks. These results suggest that the hypothesis of periodic impacts and extinction events is still viable.

    Periodic paralysis in the setting of hypokalemia can be the result of several underlying conditions, requiring systematic evaluation. Thyrotoxic periodic paralysis (TPP), a curable cause of hypokalemic periodic paralysis, can often be the first manifestation of thyrotoxicosis. Because the signs and symptoms of thyrotoxicosis can be subtle and clouded by the clinical distress of the patient, the diagnosis of the underlying metabolic disorder can be overlooked. The authors report a case of TPP in a young Chinese man in whom the diagnosis of thyrotoxicosis was initially missed. This case illustrates the lack of awareness of TPP among many physicians, delay in the diagnosis of TPP and the importance of performing thyroid function testing in all cases of periodic paralysis.

  9. Approximate analytic method for high-apogee twelve-hour orbits of artificial Earth's satellites

    2016-09-01

    We propose an approach to the study of the evolution of high-apogee twelve-hour orbits of artificial Earth's satellites. We describe parameters of the motion model used for the artificial Earth's satellite such that the principal gravitational perturbations of the Moon and Sun, nonsphericity of the Earth, and perturbations from the light pressure force are approximately taken into account. To solve the system of averaged equations describing the evolution of the orbit parameters of an artificial satellite, we use both numeric and analytic methods. To select initial parameters of the twelve-hour orbit, we assume that the path of the satellite along the surface of the Earth is stable. Results obtained by the analytic method and by the numerical integration of the evolving system are compared. For intervals of several years, we obtain estimates of oscillation periods and amplitudes for orbital elements. To verify the results and estimate the precision of the method, we use the numerical integration of rigorous (not averaged) equations of motion of the artificial satellite: they take into account forces acting on the satellite substantially more completely and precisely. The described method can be applied not only to the investigation of orbit evolutions of artificial satellites of the Earth; it can be applied to the investigation of the orbit evolution for other planets of the Solar system provided that the corresponding research problem will arise in the future and the considered special class of resonance orbits of satellites will be used for that purpose.

    Ocular trauma is one of the most common causes of unilateral morbidity and blindness in the world today. Frequency of penetrating ocular injuries and endophthalmitis after injuries caused by explosive weapons during the war in former Yugoslavia in the period 1991-1999 as well as eye injuries in the period 2000-2004 was examined. During 1991-1999, 647 patients with eye injuries were hospitalized at Eye Clinic, MMA, out of whom 500 cases with penetrating eye injuries. In 2000-2004 period, 601 patients with eye injuries were treated, out of whom 297 had penetrating eye injuries (including patients from Montenegro and Republica Srpska). All patients underwent thorough ophthalmological examination, antibiotic treatment and VPP or other required surgical interventions. All 500 patients from the first period had severe penetrating eye injuries. Intrabulbar foreign bodies (IFB) were detected in 286 cases, while 214 cases with penetrating eye injuries had no intrabulbar foreign bodies. Almost all patients had multiple head and body injuries as well. Endophthalmitis was observed in 29 eyes (5.2%) upon admission to hospital. In the second observed period (2000-2004), 196 (66%) out of 297 penetrating eye injuries had IOFB, and 101 (34%) was without IOFB. Endophthalmitis was observed in 34 eyes (8.4%). War eye injuries are a special group of injuries. Relatively low percent of posttraumatic endophthalmitis is definitely worth attention, especially in comparison with peacetime eye penetrating injuries.

    2007-05-01

    This paper outlines twelve tips for undertaking peer observation of teaching in medical education, using the peer review model and the experiences of the authors. An accurate understanding of teaching effectiveness is required by individuals, medical schools, and universities to evaluate the learning environment and to substantiate academic and institutional performance. Peer Observation of Teaching is one tool that provides rich, qualitative evidence for teachers, quite different from closed-ended student evaluations. When Peer Observation of Teaching is incorporated into university practice and culture, and is conducted in a mutually respectful and supportive way, it has the potential to facilitate reflective change and growth for teachers.

  13. Withdrawal of corticosteroids in inflammatory bowel disease patients after dependency periods ranging from 2 to 45 years: a proposed method.

    Murphy, S J

    2012-02-01

    BACKGROUND: Even in the biologic era, corticosteroid dependency in IBD patients is common and causes a lot of morbidity, but methods of withdrawal are not well described. AIM: To assess the effectiveness of a corticosteroid withdrawal method. METHODS: Twelve patients (10 men, 2 women; 6 ulcerative colitis, 6 Crohn\\'s disease), median age 53.5 years (range 29-75) were included. IBD patients with quiescent disease refractory to conventional weaning were transitioned to oral dexamethasone, educated about symptoms of the corticosteroid withdrawal syndrome (CWS) and weaned under the supervision of an endocrinologist. When patients failed to wean despite a slow weaning pace and their IBD remaining quiescent, low dose synthetic ACTH stimulation testing was performed to assess for adrenal insufficiency. Multivariate analysis was performed to assess predictors of a slow wean. RESULTS: Median durations for disease and corticosteroid dependency were 21 (range 3-45) and 14 (range 2-45) years respectively. Ten patients (83%) were successfully weaned after a median follow-up from final wean of 38 months (range 5-73). Disease flares occurred in two patients, CWS in five and ACTH testing was performed in 10. Multivariate analysis showed that longer duration of corticosteroid use appeared to be associated with a slower wean (P = 0.056). CONCLUSIONS: Corticosteroid withdrawal using this protocol had a high success rate and durable effect and was effective in patients with long-standing (up to 45 years) dependency. As symptoms of CWS mimic symptoms of IBD disease flares, gastroenterologists may have difficulty distinguishing them, which may be a contributory factor to the frequency of corticosteroid dependency in IBD patients.

  16. Stress and memory in humans: twelve years of progress?

    Science.gov (United States)

    Wolf, Oliver T

    2009-10-13

    Stress leads to an enhanced activity of the hypothalamus-pituitary adrenal (HPA) axis resulting in an increased release of glucocorticoids from the adrenal cortex. These hormones influence target systems in the periphery as well as in the brain. The present review paper describes the impact of the human stress hormone cortisol on episodic long-term memory. Starting out with our early observation that stress as well as cortisol treatment impaired declarative memory, experiments by the author are described, which result in an enhanced understanding of how cortisol influences memory. The main conclusions are that stress or cortisol treatment temporarily blocks memory retrieval. The effect is stronger for emotional arousing material independent of its valence. In addition cortisol only influences memory when a certain amount of testing induced arousal occurs. A functional magnetic resonance imaging (fMRI) study suggests that the neuronal correlate of the cortisol induced retrieval blockade is a reduced activity of the hippocampus. In contrast to the effects on retrieval cortisol enhances memory consolidation. Again this effect is often stronger for emotionally arousing material and sometimes occurs at the cost of memory for neutral material. A fMRI study revealed that higher cortisol levels were associated with a stronger amygdala response to emotional stimuli. Thus stimulatory effects of cortisol on this structure might underlie the cortisol induced enhancement of emotional memory consolidation. The findings presented are in line with models derived from experiments in rodents and are of relevance for our understanding of stress associated psychiatric disorders.

    Paenibacillus larvae is the causative agent of American Foulbrood (AFB), a deleterious disease that affects honeybees. In Uruguay it was first reported in 1999. In 2001 the bacterium was spread all over the country, and its prevalence in honey was estimated in 51%. Two P. larvae genotypes were found; ERIC I - BOX A, worldwide distributed and ERIC I - BOX C, exclusively detected in Argentina until then. In the present manuscript we analyzed the evolution of AFB outbreaks from 1999 to 2009, presented a new nation-wide survey carried out during 2011 when a prevalence of 2% was found and discuss national strategies for prevention of the disease. Since Uruguay is a small country where almost all beekeepers are registered, Uruguayan experience can be useful to be applied in other countries.

    The effects of smoking habits, socio-occupational factors and respiratory symptoms in the development of airflow obstruction have been studied in a working population of 575 men aged 30-54 in 1960 and surveyed in 1960 and 1972. On average, FEV1 decreased by 47 ml/annum. Apart from FEV1 level, which reflects loss since the beginning of adult life, three factors were independently related to FEV1 slope: tobacco consumption, occupational exposure and social class. The decrease of FEV1 with smoking was dose related and decelerated among those who stopped smoking. This follow-up study ruled against phlegm as a causal factor of early stage airflow obstruction, although its role is not excluded at later stages.

    To analyze the types of articles and authorship characteristics of three orthodontic journals--American Journal of Orthodontics and Dentofacial Orthopedics (AJODO), The Angle Orthodontist (AO), and European Journal of Orthodontics (EJO)--published between 2008 and 2012 and to assess the differences in content within this period and an earlier period of 1998 to 2002. Each journal's content was accessed through the web edition. From each article, the following parameters were recorded: article type, number of authors, number of affiliations, source of article (referring to the first author's affiliation), and geographic origin. Descriptive statistics were performed and selected parameters were analyzed with the Pearson chi-square or Fisher exact test for independence at the .05 level of significance. Review of differences between the two periods showed that the number of publications was almost double. The percentages of multi-authored articles increased. Fewer studies derived from the United States/Canada and European Union countries. Increases for articles from non-European Union countries, Asia, and other countries were found. Characteristics of the second period showed that the EJO and AO published more research articles, whereas the AJODO regularly published case reports and other articles. Approximately 75% of all studies derived from orthodontic departments. The publications from 1998-2002 and 2008-2012 were significantly different both in terms of numbers and characteristics. Within 2008-2012 there were notable differences between the three journals concerning the type and origin of the publications.

    The critical period for language acquisition is often explored in the context of second language acquisition. We focus on a crucially different notion of critical period for language, with a crucially different time scale: that of a critical period for first language acquisition. We approach this question by examining the language outcomes of children who missed their critical period for acquiring a first language: children who did not receive the required language input because they grew in isolation or due to hearing impairment and children whose brain has not developed normally because of thiamine deficiency. We find that the acquisition of syntax in a first language has a critical period that ends during the first year of life, and children who missed this window of opportunity later show severe syntactic impairments.

    In a previous study, high levels of maternal criticism predicted increased behavior problems in adolescents and adults with autism spectrum disorders (ASD) over an 18-month period (Greenberg, Seltzer, Hong, & Orsmond, 2006). The current investigation followed these families over a period of 7 years to examine the longitudinal course of criticism and behavior problems, to assess the association between their trajectories, and to determine the degree to which change in each of these factors predicted levels of criticism and behavior problems at the end of the study period. A sample of 118 mothers coresiding with their adolescent and adult children with ASD provided open-ended narratives about their children and reported on the children's behavior problems at 4 waves. Maternal criticism was derived from expressed emotion ratings of the narratives. Criticism exhibited low but significant stability over the 7-year period, and behavior problems exhibited high stability. Through latent growth curve modeling, (a) criticism was found to have increased over time, but only for the group of families in which the sons or daughters transitioned from high school services during the study period; (b) individual changes in criticism and behavior problems were positively correlated over the 7-year period; and (c) changes in criticism predicted levels of behavior problems at the conclusion of the study. Changes in behavior problems were not predictive of end levels of criticism. Implications for intervention and prevention efforts are discussed.

    In a previous study from our laboratory, high levels of maternal criticism predicted increased behavior problems in adolescents and adults with autism spectrum disorders (ASD) over an 18-month period (Greenberg, Seltzer, Hong, & Orsmond, 2006). The current investigation followed these families over a period of seven years to examine the longitudinal course of criticism and behavior problems, to assess the association between their trajectories, and to determine the degree to which change in each of these factors predicted levels of criticism and behavior problems at the end of the study period. A sample of 118 mothers co-residing with their adolescents and adults with ASD provided open-ended narratives about their children and reported on the children's behavior problems at four waves. Maternal criticism was derived from expressed emotion ratings of the narratives. Criticism exhibited low but significant stability over the seven year period and behavior problems exhibited high stability. Using latent growth curve modeling, (a) criticism was found to have increased over time, but only for the group of families in which the sons or daughters transitioned from high school services during the study period, (b) individual changes in criticism and behavior problems were positively correlated over the seven-year period, and (c) changes in criticism predicted levels of behavior problems at the conclusion of the study.

    Characteristic feature of PFAPA syndrome is periodic episodes of fever recurring in 21-28 days in infants and young children. Fever is accompanied by aphtosus stomatitis, pharyngitis and cervical adenopathy. Diagnosis of this syndrome are based on typical clinical manifestations, because there are no characteristic changes in laboratory findings. The reason of this syndrome is unknown. We described a case of 4 years old girl with typical manifestations of this syndrome. We excluded others reasons of periodic fever. PFAPA syndrome passed after 2 years of duration after adenothomy.

  10. KIC 2831097 - A 2-year orbital-period RR Lyrae binary candidate

    2016-01-01

    We report the discovery of a new Kepler first-overtone RR Lyrae pulsator, KIC 2831097. The pulsation shows large, 0.1 d amplitude, systematic phase variations that can be interpreted as light travel-time effect caused by orbital motion in a binary system, superimposed on a linear pulsation-period decrease. The assumed eccentric (e=0.47) orbit with the period of approximately 2 yr is the shortest among the non-eclipsing RR Lyrae binary candidates. The binary model gives a lowest estimate for the mass of the companion of 8.4 M_Sun, that places it among black hole candidates. Beside the first-overtone pulsation, numerous additional non-radial pulsation frequencies were also identified. We detected an ~47-d Blazhko-like irregular light-curve modulation.

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

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

    2017-03-01

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

    Continuous spectral EEG activity monitoring has been used in adults as a monitor of brain activity during anesthesia. It has not been used in infants. We studied 22 infants less than 7 months old undergoing minor surgery. Halothane alone or minimal Halothane anesthesia associated with caudal epidural anesthesia were used. Life-Scan analysis, in spite of wide individual variations, allowed us to detect infraclinical hypoxia episodes, it provided informations about operative confort, depth of anesthesia and added in the post-operative period an objective criteria to clinical evaluation of pain. A wide use of such a monitoring is warranted in infants.

  3. Combining ability of twelve maize populations

    2002-01-01

    Full Text Available Genetic progress depends on germplasm quality and breeding methods. Twelve maize populations and their crosses were evaluated to estimate combining ability and potential to be included as source populations in breeding programs. Plant height, point of insertion of the first ear, number of ears per plant, number of grains per ear, root and stalk lodging and grain yield were studied in two locations in Brazil, during the 1997/98 season. Genotype sum of squares was divided into general (GCA and specific (SCA combining ability. Results indicated the existence of genetic divergence for all traits analyzed, where additive effects were predominant. The high heterosis levels observed, mainly in Xanxerê, suggested the environmental influence on the manifestation of this genetic phenomenon. Populations revealed potential to be used in breeding programs; however, those more intensively submitted to selection could provide larger genetic progress, showing the importance of population improvement for the increment of the heterosis in maize.

    Anemia during pregnancy is associated with adverse outcomes including maternal and perinatal mortality. However, health education and other public health strategies seeking to reduce its prevalence have usually met with only limited success. The study reported here surveyed anemia of pregnancy on the island of Montserrat in 1980, 1985, and 1990. This involved examination of clinic and hospital records for over 90% of all women giving birth on Montserrat in 1980 and 1985, as well as 80% of those giving birth in 1990. This examination showed a dramatic reduction in the prevalence of anemia at the time of the first prenatal visit (a drop from 82% of the study women in 1980 to 23% in 1985 and 19% in 1990) and also a marked drop at three days postpartum (from 91% in 1980 to 41% in 1985 and 39% in 1990). Logistic regression analyses indicated that after controlling for three possible confounding factors (maternal age, parity, and weeks of gestation at first prenatal visit) the difference between the risk of developing anemia during pregnancy in 1980 as compared to 1985 or 1990 was still highly significant. The reasons for the observed drop in anemia's prevalence during the survey period are not entirely clear, partly because of the retrospective nature of the study. However, better nutrition resulting from improvement in the standard of living on Montserrat during the survey period could have been important, as could changes in health education and food supplementation activities.

  5. Length of Growing Period over Africa: Variability and Trends from 30 Years of NDVI Time Series

    Full Text Available The spatial distribution of crops and farming systems in Africa is determined by the duration of the period during which crop and livestock water requirements are met. The length of growing period (LGP is normally assessed from weather station data—scarce in large parts of Africa—or coarse-resolution rainfall estimates derived from weather satellites. In this study, we analyzed LGP and its variability based on the 1981–2011 GIMMS NDVI3g dataset. We applied a variable threshold method in combination with a searching algorithm to determine start- and end-of-season. We obtained reliable LGP estimates for arid, semi-arid and sub-humid climates that are consistent in space and time. This approach effectively mapped bimodality for clearly separated wet seasons in the Horn of Africa. Due to cloud contamination, the identified bimodality along the Guinea coast was judged to be less certain. High LGP variability is dominant in arid and semi-arid areas, and is indicative of crop failure risk. Significant negative trends in LGP were found for the northern part of the Sahel, for parts of Tanzania and northern Mozambique, and for the short rains of eastern Kenya. Positive trends occurred across western Africa, in southern Africa, and in eastern Kenya for the long rains. Our LGP analysis provides useful information for the mapping of farming systems, and to study the effects of climate variability and other drivers of change on vegetation and crop suitability.

  12. The twelve theses: a call to a new reformation

    Full Text Available With every discovery emerging from the world of science over the last 500 years concerning the origins of the universe and of life itself, the traditional explanations offered by the Christian Church appeared to be more and more dated and irrelevant.  Christian leaders, unable to embrace the knowledge revolution seemed to believe  that the only way to save Christianity was not to disturb the old patterns either by listening to, much less by entertaining the new knowledge. I tried to articulate this challenge in a book entitled: Why Christianity Must Change or Die, published in 1998.  In that book I examined in detail the issues that I was convinced Christianity must address. Shortly after that book was published I reduced its content to twelve theses, which I attached in Luther-like fashion to the great doors on the Chapel of Mansfield College at Oxford University in the United Kingdom. I then mailed copies of those Twelve Theses to every acknowledged Christian leader of the world. It was an attempt to call them into a debate on the real issues that I was certain the Christian Church now faced.  I framed my twelve theses in the boldest, most provocative language possible, designed primarily to elicit response and debate. I welcome responses from Christians everywhere.  I claim no expertise or certainty in developing answers, but I am quite confident that I do understand the problems we are facing as Christians who are seeking to relate to the 21st century.

    Objective : To describe the epidemiology of orofacial clefts in the east of Ireland. Design and Setting : A descriptive epidemiologic study on 851 cases of orofacial cleft identified over a 25-year period from 1984 to 2008 from more than 500,000 births. Results : There were 438 (51.5%) cases of cleft lip with or without cleft palate and 413 (48.5%) cases of cleft palate. The total birth prevalence was 16.0 per 10,000 births for all orofacial clefts, 8.2 for cleft lip with or without cleft palate, and 7.8 for cleft palate. Of all cases, 63.7% (542/851) occurred as isolated anomalies, 21.5% (183/851) were associated with multiple anomalies, and 14.8% (126/851) were associated with a syndrome or chromosomal anomaly. A significantly increasing trend over the 25-year period was observed for cleft lip with or without cleft palate associated with syndromes or chromosomal anomalies among mothers younger than 35 years but not in those older than 35 years. Conclusion : A slightly higher rate of orofacial clefts was observed in the east of Ireland than was observed in European and multinational studies during the study period, and there were higher rates of cleft palate. The rising trend in the proportion of mothers aged 35 years or older in Ireland is not contributing significantly to orofacial clefts associated with chromosomal syndromes.

  14. Changes in strength over a 2-year period in professional rugby union players.

    The purpose of this study was to assess the magnitude of upper and lower body strength changes in highly trained professional rugby union players after 2 years of training. An additional purpose was to examine if the changes in strength were influenced by the starting strength level, lean mass index (LMI), or chronological age. This longitudinal investigation tracked maximal strength and body composition over 3 consecutive years in 20 professional rugby union athletes. Maximal strength in the bench press and back squat and body composition was assessed during preseason resistance training sessions each year. The athletes completed a very rigorous training program throughout the duration of this study consisting of numerous resistance, conditioning and skills training sessions every week. The primary findings of this study were as follows: (a) Maximal upper and lower body strength was increased by 6.5-11.5% after 2 years of training (p = 0.000-0.002 for bench press; p = 0.277-0.165 for squat); (b) magnitude of the improvement was negatively associated with initial strength level (r = -0.569 to -0.712, p ≤ 0.05); (c) magnitude of improvement in lower body maximal strength was positively related to the change in LMI (an indicator of hypertrophy; r = 0.692-0.880, p ≤ 0.05); and (d) magnitude of improvement was not associated with the age of professional rugby union athletes (r = -0.068 to -0.345). It appears particularly important for training programs to be designed for continued muscle hypertrophy in highly trained athletes. Even in professional rugby union athletes, this must be achieved in the face of high volumes of aerobic and skills training if strength is to be increased.

    Thoracic sympathectomy is considered the most effective method to treat palmar hyperhidrosis. We developed a novel approach for thoracic sympathectomy in patients with palmar hyperhidrosis through the umbilicus, using an ultrathin gastroscope. The aim of this study was to evaluate the continuing efficacy and patient satisfaction of this innovative surgery. All procedures were performed under general anesthesia and the patients were intubated with a dual-lumen endotracheal tube. After a 5-mm umbilical incision, the muscular parts of the diaphragmatic dome were incised with a needle-knife and the nasal gastroscope was advanced into the thoracic cavity. The sympathetic chain was identified at the desired thoracic level and ablated with hot biopsy forceps. All patients were followed up for at least 1 year after the procedure through clinic visits or telephone/e-mail interviews. From April 2010 to August 2011, a total of 35 patients underwent a transumbilical thoracic sympathectomy. Fifty-seven percent were male patients, with a mean age of 21.2 years (range, 16-33 years). The success rate after 12 months was 97.1% (34 of 35) for isolated palmar hyperhidrosis and 72.2% (13 of 18) for axillary hyperhidrosis. Compensatory sweating was reported in 28.6% of patients at the 1-year follow-up evaluation. There was no mortality, no diaphragmatic hernia, and no Horner syndrome was observed. Quality of life related to hyperhidrosis improved substantially in 27 (77.1%) patients, and improved in 4 (11.4%) patients at 12 months after surgery. A total of 94.3% of patients were satisfied with the excellent cosmetic results of the surgical incision. Transumbilical thoracic sympathectomy is an efficacious alternative to the conventional approach. This technique avoided the chronic pain and chest wall paresthesia associated with the chest incision. In addition, this novel procedure afforded maximum cosmetic benefits.

    2010-01-01

    The purposes of this study were to describe (1) the types of exercise participation of adolescents with cerebral palsy; (2) the weekly duration of stretching, strengthening, and cardiovascular exercise; (3) how the level of activity compares with national health guidelines; and (4) the change in participation over 4 years. Participants included 126 males and 104 females (mean age = 14.7 years, SD = 1.7 years) who reported physical activities in the previous week. Analyses included frequency counts and proportions, stacked bar graphs, and 2-way analyses of variance of exercise participation by Gross Motor Function Classification System (GMFCS) and sex. A significant main effect of GMFCS level was detected for light and moderate exercise. A significant interaction of GMFCS level and sex was found for stretching; females stretched more. An average of 9.4% and 11.4% of our sample participated in weekly levels of moderate and vigorous exercise, respectively. Pediatric physical therapists should promote increased exercise participation rates among youths with cerebral palsy.

    Full Text Available Cystic lesions of the jaws are common pathologic entity. Aim: The analysis of a case series of cystic lesions of the jaws. Material and Method: Retrospective study of the cases of cystic lesions, which were managed in our department during the years 2010 - 2012 was conducted. The following inclusion criteria of a case in the study were defined: maximum diameter of the lesion at least 2cm, surgical treatment of the lesion under general anesthesia and postoperative follow-up of the patient for at least one year. Results: 56 cases were analyzed. Average age of the patients was 48.2 years and the average maximum diameter of the lesions was 3.86cm. Almost all cases were managed by enucleation (49/56– 87.5%. Decompression was implemented in 5 cases (8.9%. In all cases, except for one where recurrence was observed, the result was cure of the lesion. The use of bone graft was correlated in statistically significant degree with seemingly quicker bone regeneration, but also with an increased risk of immediate postoperative wound dehiscence. Conclusions: Enucleation as well as decompression were proven to be good methods, as their use provided satisfactory results in all cases. The results of bone allograft application were controversial and therefore its use must be studied more thoroughly.

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

    Ozone is one of the most harmful pollutants in the troposphere. High ozone concentrations can damage plants, animals and humans. The damaging effects depend on the magnitude of a critical level of a special parameter, the cumulative ozone exposure. This is why cumulative ozone exposures must be carefully studied. It is important to determine the relationships between relevant emissions (NOx emissions, human-made VOC emissions, and/or a combination of NOx emissions and human-made VOC emissions) and cumulative ozone exposures. All these issues are discussed in this paper. Meteorological data from seven consecutive years, from 1989 to 1995, have been used in the experiments with different scenarios for varying the emissions (the NOx emissions, the human-made VOC emissions, as well as both the NOx emissions and the human-made VOC emissions). The particular air pollution model used in this study is the Danish Eulerian Model. Several hundred runs with different input data (meteorological data and/or emission data) have been performed. Advanced visualization techniques are used to interpret the large amount of digital data collected in these runs and to show clearly different trends and relationships that are normally hidden behind millions and millions of numbers. The model results were compared with measurements taken at more than 80 stations located in different European countries. The experiments indicate that it is sufficient to carry out computations over 5 consecutive years in order to eliminate the influence of extreme meteorological conditions (very warm or very cold summer months) on the cumulative ozone exposures, while this effect is clearly seen if less than 5 years are used in the experiments. It is shown that the relationship between the emissions (NOx and/or human-made VOC emissions) and the cumulative ozone exposures is in general nonlinear. Finally, it is illustrated that the critical values for ozone exposures are exceeded in most of Europe (in many

    A survey of all patients in whom liver biopsy showed epithelioid granulomas was undertaken at two major teaching hospitals in Glasgow for the period 1970-1979. Seventy-seven patients with hepatic granulomas were studied retrospectively. In 53 cases (69 per cent) a clear-cut clinical diagnosis was established, which included sarcoidosis (eight cases), tuberculosis (eight), extrahepatic biliary obstruction (seven), primary liver diseases (11), neoplasm (six), bacterial infection (five) and miscellaneous (eight). In 24 patients (31 percent) no cause was found. Seventeen patients from this idiopathic group were studied prospectively and single examples of the following conditions were subsequently diagnosed; pulmonary tuberculosis, primary biliary cirrhosis, ulcerative colitis, adenocarcinoma of rectum, primary hepatocellular carcinoma, alpha-one antitrypsin deficiency and pulmonary fibrosis, sarcoidosis, pulmonary fibrosis alone, gallstones, rheumatic heart disease, unexplained hepatosplenomegaly and one death from mesenteric artery thrombosis. Only six cases remained truly idiopathic. Three of these patients recovered and in two liver biopsy became normal. The other three have persistent granulomas associated with continuing illness.

    Full Text Available Football is currently the most popular sport in the world. The competitive nature of the sport makes it prone to injuries with the estimated frequency being 10 to 35 per 1000 playing hours (Dvorak and Junge, 2000. The aim of this study was to identify the injury patterns and rehabilitation periods with specific injuries in a premiership football club. Player injuries were retrospectively analysed from a local database (Microsoft Access 2000 at the Blackburn Rovers Football Club, UK from December 1998 to March 2004. The club physiotherapist and physician recorded details of all injuries sustained during both training and matches during that period. Clear distinctions were made between acute and overuse injuries and rehabilitation times for each injury were noted (Arnason et al., 2004. Data was analysed using SPSS (Chicago, Illinois, USA. Differences between the groups were assessed using the independent samples t-test. P values of < 0.05 were considered statistically significant. There were 483 injuries in 91 players. Of these 133 injuries occurred as a result of overuse and 350 as a result of direct trauma. 440 injuries were treated conservatively while 43 were treated operatively. Table 1 shows the range and number of injuries, which occurred during this period along with the average rehabilitation time for each injury. Injuries grouped as "Other" in table 1 accounted for less than 1% of all injuries and could not always be directly attributed to football even though this appeared to be the precipitating factor in all cases. There was no statistical difference between rehabilitation times for acute injuries (18 days, standard deviation 30 as compared to overuse injuries (20 days, standard deviation 39 (p = 0.640. The mean rehabilitation time however for injuries treated conservatively (15 days , standard deviation 24 as compared to injuries treated surgically (61 days, standard deviation 67 was found to be statistically significant (p = 0

    2010-09-01

    Full Text Available Aim: A statistical analysis of the epidemiology of head and neck soft tissues conditions was carried out. Material and Method: The patients with head and neck infections who received treatment at Ist Oral and Maxillofacial Surgery Clinics of Cluj-Napoca between January 2000 and December 2009 inclusively were included in this study. Results: 1008 patients accomplished the inclusion criteria. The starting point of the head and neck inflammatory conditions was represented mainly by dental-periodontal lesions (79.66%. Most of the infections were localized at the level of a single cavity (81.85%; when more than one cavity was affected the patients were had also systemic conditions. When septic metastases spread the most affected side was the mediastinal structures. All patients included in this study received surgical treatment, most frequently two surgical interventions being necessary (50.20%. The post-surgical evolution was favorable for 1005 patients with an average of hospitalization period of 6.11 days, the hospitalization stay being also influenced by the presence or absence of the systemic immunodepression. Conclusion: The present research identified that the inflammatory conditions of the head and neck have as major starting point the dental-periodontal inflammatory conditions. The surgical treatment is the best choice for curing these affections.

    Full Text Available Introduction: Eye injuries represent one of the biggest problems in eye surgery all around the world, including our country. Treatment of eye injuries demands highly skilled personnel and adequate technical equipment. Objective: To show a total number of eye injuries, including the surgical methods used for their treatment. Methods: In our study, retrospective analysis of all performed surgical methods used in treatment of hospitalized patients in our Clinic during 2000-2004 was carried out. A special attention was paid to pars plana vitrectomy, together with combined anterior-posterior segment procedures. Results: During 2000-2004, a total of 347 pars plana vitrectomy, and 27 traumatic retinal detachments (conventional methods were performed. In addition, 314 patients with contusion trauma of the eyes were treated. Out of 297 patients with penetrant eye injuries, 196 (66% had intraocular foreign bodies (IOFB, and 101 (34% were without IOFB. A total number of endophthalmitis was 34 (8.73%. The number of combined anterior-posterior segment operations during this period was 227. Conclusion: Vitreoretinal operations are the most prevailing in treatment of serious eye injuries. Pars plana vitrectomy is also the most common method of surgical treatment of eye injuries.

    Full Text Available The objective of this study was to evaluate performance and daytime ingestive behavior of 84 Nellore young bulls in the post-weaning phase kept on Brachiaria brizantha cv. Marandu pastures during the dry season. Treatments were protein mineral supplementation (1 g/kg body weight and protein+energy mineral supplementation (3 g/kg body weight. The experimental area comprised 12 paddocks in a total area of 27.36 ha, divided in two blocks of six paddocks each, having three replications per treatment in each block, with 42 animals/treatment. The data were subjected to variance analysis with repeated measures over time via procedure PROCMIXED of SAS (Statistical Analysis System, version 9.0 and means were compared by the Tukey test at 5% probability. The initial average weight of animals was 204.8 kg; final weights were 260.9 and 276.9 kg for animals that received protein and protein+energy supplement, respectively. The forage availability, sward height and stocking rate values did not differ with supplementation, but they showed difference between the experimental periods. The average time spent grazing during daylight of animals fed protein+energy supplement was shorter as compared with those which consumed protein supplement. Animals kept under the same pasture conditions during the dry season show better performance when they receive protein+energy supplement than protein supplement.

    Based on the samples of 113,468 publications on environmental assessment (EA) from the past 20 years, we used a bibliometric analysis to study the literature in terms of trends of growth, subject categories and journals, international collaboration, geographic distribution of publications, and scientific research issues. By applying thresholds to network centralities, a core group of countries can be distinguished as part of the international collaboration network. A frequently used keywords analysis found that the priority in assessment would gradually change from project environmental impact assessment (EIA) to strategic environmental assessment (SEA). Decision-theoretic approaches (i.e., environmental indicator selection, life cycle assessment, etc.), along with new technologies and methods (i.e., the geographic information system and modeling) have been widely applied in the EA research field over the past 20 years. Hot spots such as “biodiversity” and “climate change” have been emphasized in current EA research, a trend that will likely continue in the future. The h-index has been used to evaluate the research quality among countries all over the world, while the improvement of developing countries' EA systems is becoming a popular research topic. Our study reveals patterns in scientific outputs and academic collaborations and serves as an alternative and innovative way of revealing global research trends in the EA research field.

    Cannabis contains a unique class of compounds known as the cannabinoids. Pharmacologically, the principal psychoactive constituent is Δ(9)-tetrahydrocannabinol (THC). The amount of THC in conjunction with selected additional cannabinoid compounds (cannabidiol/CBD, cannabinol/CBN), determines the strength or potency of the cannabis product. Recently, reports have speculated over the change in the quality of cannabis products, from nearly a decade, specifically concerning the increase in cannabinoid content. This article exploits the analytical data of cannabis samples analyzed in the five French forensic police laboratories over 25 years. The increase potency of both herbal and resin cannabis in France is proved through the monitoring of THC content. For cannabis resin, it has slowly risen from 1992 to 2009, before a considerable increase in the last four years (mean THC content in mid-2016 is 23% compared to 10% in 2009). For herbal cannabis, it has known three main stages of growth (mean THC content is 13% in 2015 and mid-2016 compared to 7% in 2009 and 2% in 1995). The calculation of THC/CBD ratios in both herbal and resin samples confirms the recent change in chemotypes in favor of high potency categories. Finally, the CBN/THC ratios in marijuana samples were measured in order to evaluate the freshness of French seized hemp.

    The study investigated the clinical performance of 387 space maintainers fitted in 358 patients aged from 3 to 9 years in the Department of Pediatric Dentistry at the Faculty of Dentistry-University of Jordan from 1996 to 2000. Failure occurred in 119 appliances (30.7%), of which 49.6% were due to solder breakage, 32.8% from cement loss, 11% from soft tissue lesions, 4.2% from eruption interference, and 2.5% were completely lost. By using the Kaplan-Meier method, the estimated median survival time for space maintainers was 18 months. Lingual arches had the lowest median survival time of 14 months. Bands and loops, Nance appliances, and removable partial dentures had similar probability of survival. Fixed bilateral mandibular appliances recorded lower survival time than fixed bilateral maxillary appliances. Gender, age, type of dentition, fixed vs. removable, year of placement of the appliance and number of space maintainers fitted simultaneously in the same patient had no significant effect on survival of the appliances.

    BACKGROUND: Ectopic pancreas is defined as pancreatic tissue found outside its usual anatomical position, with no ductal or vascular communication with the native pancreas. We describe a case of ectopic pancreas of the small bowel and mesentery causing recurrent episodes of pancreatitis, initially suspected on computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP), and confirmed on histological review of the resection. METHODS: A 67-year-old woman presented with clinical symptoms and biochemical evidence of pancreatitis. She had similar episodes over the past 30 years with unrevealing investi-gations, and was concluded to have idiopathic pancreatitis. She underwent CT and MRCP, with findings suggestive of ectopic pancreas, a diagnosis confirmed on histology of the resection. RESULTS: MRCP identified a mass in the proximal small bowel mesentery isointense to the native pancreas, with a small duct draining into a proximal jejunal loop. The resected specimen consisted of normal parenchyma with lobulated acinar tissue with scattered islets of Langerhans, an occasional ductular structure, and admixed areas of adipose tissue. The patient remained asymptomatic with normal biochemistry six months post-operatively. CONCLUSION: In an individual with abdominal pain, elevated serum amylase/lipase, but imaging findings of a normal native pancreas, ectopic pancreatitis should be considered, and can be evaluated by CT and MRCP.

    We described the case of a patient with recurrent episodes of isolated diplopia over the last 30 years. On her last event, neurological examination revealed not only a right third and sixth cranial nerves involvement, but also a right peripheral facial palsy and a motor weakness on the left ulnar territory. Electrophysiological nerves motor conduction study revealed a conduction block on the left ulnar nerve and a less severe on the right ulnar nerve. Asymmetrical upper limb sensorimotor weakness combined with conduction block and cranial nerves palsy led to a diagnosis of Lewis and Sumner syndrome (LSS). This case is unusual by the presentation of the disease and is, to our knowledge the longer natural disease course of LSS reported. Moreover, it suggests that the recurrent diplopia variant may represent a separate entity with a good prognosis even in absence of invasive treatment.

    Full Text Available The primary aim of this paper is to provide a rationale for the necessity of intervening with a physical activity intervention in the preschool years and why the daycare environment is amenable to such intervention. We also review the prevalence of physical activity, sedentary behaviour and obesity in the preschool population and the impact that these lifestyle behaviours and conditions have on the health of preschool aged children, as secondary objectives. Moreover we discuss implications for intervention and research using a “lessons learned” model based on our research team’s experience of conducting a randomized controlled trial aimed at increasing physical activity, reducing sedentary behaviour and improving motor skill development and body composition in preschoolers. Lastly, we make conclusions based on the literature and highlight issues and directions that need to be addressed in future research in order to maximize health promotion and chronic disease prevention in the pediatric population.

    Full Text Available A knowledge gap exists in the role of restaurant type on the prediction of attaining the highest grade possible from the local health inspection agency. This study identified disparities using logistic regression between the issuance of a Grade A and restaurant type and location. This study tested the eight most inspected types of restaurants within the City of New York and calculated the odds ratios of their receiving the highest inspection grade by the New York City Department of Health and Mental Hygiene. A fitted equation has been proposed for the prediction of receiving the highest inspection grade based upon the citywide results of these eight restaurant types from calendar years 2011 and 2012. The results suggest that certain styles of restaurants have lower odds of receiving the highest grade in comparison to American-style restaurants.

    There's a fact, that Hungary has held the first places in suicidal statstics. The authors studied toxicological cases between 1989 and 1998 at the 1st Department of Medicine of the Medical and Health Science Centre, at the University of Debrecen, paying special attention to suicidal poisoning cases. 2% of the patient turnover accounted for acute poisoning cases, the number of which increased during the 10 years in question. 70% of the cases were of suicidal intentions, 20% were unintentional, these poisonings were not committed on purpose, while the proportion of iatrogenic intoxication cases was 10%. Amongst the failed suicide cases there was a higher proportion of women, whereas a higher percentage of men accounted for "successful" suicide cases. When examining auto-intoxication cases it turned out that the medicine most frequently used was meprobamate, besides benzodiazepines. Mortality rate was highest in the glutethimide intoxication cases. Most poisonings with suicidal intentions took place in the 2nd quarter of the year. Most completed suicides were committed on Wednesdays and Thursdays. 81% of the iatrogenic intoxication cases happened to be with digitalis and coumarin overdose. Nearly 50% of the cases turned out to be combined intoxications. 40% of the men took alcoholic drinks during the auto-intoxications. In the case of 135 patients extracorporeal detoxification therapy was applied, which consisted mostly of hemoperfusion. Three quarters of the patients needed psychiatric care and every fourth patient was admitted to the Department of Psychiatry. 6.9% of the poisonings were fatal. The growing number of toxicological cases--amongst these suicidal poisonings--compels us to pay more attention to the setting up of interdisciplinary based prevention as well as running effective toxicological centres. All physicians have a responsibility to recommend psychiatric care for people suffering from mental problems or depression and for the unsuccessful or potential

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

    A fungal ball consists of a dense conglomerate of fungal hyphae growing at the surface of the sinus mucosa without tissue infiltration. The maxillary sinus is by far the most commonly involved paranasal sinus cavity followed by the sphenoid sinus. The present study is a retrospective study of 25 consecutive cases treated during the last 10 years in the two hospitals be- longing to the Catholic University of Louvain (CHU Mont-Godinne and UCL Saint Luc). We report the symptomatology, the imaging and discuss the different surgical managements. We conclude that the clinician must have a high index of suspicion when dealing with a unilateral rhinosinusitis persisting despite a maximal and well conducted medical treatment. This is particularly so in elderly women when associated with facial pain and post nasal drip, particularly when the computed tomography shows an unilateral opacity of the sphenoid sinus with or without a sclerosis or an erosion of the bony walls, a polyp in the sphenoethmoidal recess or a hyperdensity mimicking a foreign body. An endonasal endoscopic sphenoidotomy is the treatment of choice in most cases, allowing good ventilation of the sinus and radical removal of all the fungal concretion. A biopsy of the sinus mucosa adjacent to fungal elements is of upmost important to confirm the non- invasiveness of the fungi within the tissue. Antifungal medication is not required in uncomplicated forms. All host factors producing some degree of immunosuppression must be corrected when present and must alert the clinician to rule out any forms of invasive disease.

    Full Text Available Objectives: The aim of this study was to evaluate the results of the patients who underwent cervical cerclage placement and the contribution of this intervention to the maintenance of pregnancy.Methods: Data of 29 patients who underwent cervical cerclage placement due to cervical insufficiency in Ataturk University Medical Faculty Obstetrics and Gynecology Department Between January 2002 and April 2007 were retrospectively analyzed.The patient’s age, gestational week, history of abortion, history of previous cervical cerclage, preoperative measurement of cervical length, types of cerclage and delivery weeks were recorded and analysed.Results: The patient’s ages were between 24 and 43 years. Weeks of gestation were between 12 weeks 2 days and 26 weeks and 1 day. Nineteen patient’s cervical lengths were less than 20 mm by transvaginal ultrasonography. Eight of patients had funneling sign by transvaginal ultrasonography. Sixteen patients treated with prophylactic cervical cerclage, thirteen women treated with therapeutical cerclage. The cervical lengths of twenty one patients were over 20 mm after the procedure. Five patients reached term.Conclusion: The patient who has risk for cervical insufficiency should be followed with serial ultrasound examination and cervical cerclage should be performed when needed. The prophylactic cerclaje process is still best choice for patients with the history of two or more painless 2nd trimester or early 3rd trimester abortion that typical for cervical incompetence.

Rejection after the first submission is likely, and when this occurs authors should (9) get it back out the door quickly, but first (10) take seriously all reviewer and editor suggestions. Finally, when the invitation comes to revise and resubmit, authors should (11) respond carefully to every reviewer suggestion, even if they disagree, and (12) get input from others as they revise. The author also shares detailed suggestions on the creation of effective tables and figures, and on how to respond to reviewer critiques.

  20. Antifouling activity of twelve demosponges from Brazil

    Directory of Open Access Journals (Sweden)

    SM. Ribeiro

    Full Text Available Benthic marine organisms are constantly exposed to fouling, which is harmful to most host species. Thus, the production of secondary metabolites containing antifouling properties is an important ecological advantage for sessile organisms and may also provide leading compounds for the development of antifouling paints. High antifouling potential of sponges has been demonstrated in the Indian and Pacific oceans and in the Caribbean and Mediterranean seas. Brazilian sponges remain understudied concerning antifouling activities. Only two scientific articles reported this activity in sponges of Brazil. The objective of this study was to test crude extracts of twelve species of sponges from Brazil against the attachment of the mussel Perna perna through laboratorial assays, and highlight promising species for future studies. The species Petromica citrina, Amphimedon viridis, Desmapsamma anchorata, Chondrosia sp., Polymastia janeirensis, Tedania ignis, Aplysina fulva, Mycale angulosa, Hymeniacidon heliophila, Dysidea etheria, Tethya rubra, and Tethya maza were frozen and freeze-dried before extraction with acetone or dichloromethane. The crude extract of four species significantly inhibited the attachment of byssus: Tethya rubra (p = 0.0009, Tethya maza (p = 0.0039, Petromica citrina (p = 0.0277, and Hymeniacidon heliophila (p = 0.00003. These species, specially, should be the target of future studies to detail the substances involved in the ability antifouling well as to define its amplitude of action.

  1. Twelve Elastic Constants of Betula platyphylla Suk.

    Wood elastic constants are needed to describe the elastic behaviors of wood and be taken as an important design parameter for wood-based composite materials and structural materials. This paper clarified the relationships between compliance coefficients and engineering elastic constants combined with orthotropic properties of wood, and twelve elastic constants of Betula platyphylla Suk. were measured by electrical strain gauges. Spreading the adhesive quantity cannot be excessive or too little when the strain flakes were glued. If excessive, the glue layer was too thick which would influence the strain flakes' performance, and if too little, glues plastered were not firm, which could not accurately transmit the strain. Wood as an orthotropic material, its modulus of elasticity and poisson's ratios are related by two formulas:μij /Ei =μji /Ej and μij 0.95) between the reciprocal of elastic modulus MOE-1 and the square of the ratio of depth to length (h/l)2, which indicate that shear modulus values measured were reliable by three point bending experiment.

    There have been changes in the national policy regarding population growth in Malaysia from 1982. This report studies the changes in contraceptive practice among the three racial groups in this country, i.e. Malays, Chinese and Indians, over a 5-year period with an interval of 10 years. This is a retrospective study based on the attendance at the same family planning clinic in an urban setting. The striking change noted is the change in the racial composition of contraceptive usage in the two study periods with a shift from the Chinese being predominant in 1975-1979 to Malays in 1985-1989. There was no change among the numbers of Indians using contraception. The results also reveal a significant trend of change for users of the pill and those undergoing sterilization. There were no significant changes in IUD, condom and injectable usage. The study demonstrates how national policies, level of education and rural urban migration can significantly alter contraceptive practice.

    New optical and radio data on the BL Lacertae object AO 0235+16 have been collected in the last four years by a wide international collaboration, which confirm the intense activity of this source. The optical data also include the results of the Whole Earth Blazar Telescope (WEBT) first-light campaign organized in November 1997. The optical spectrum is observed to basically steepen when the source gets fainter. We have investigated the existence of typical variability time scales and of possible correlations between the optical and radio emissions by means of visual inspection, Discrete Correlation Function analysis, and Discrete Fourier Transform technique. The major radio outbursts are found to repeat quasi-regularly with a periodicity of about 5.7 years; this period is also in agreement with the occurrence of some of the major optical outbursts, but not all of them.

    2010-06-01

    Full Text Available Abstract Background Transgenic trees currently are being produced by Agrobacterium-mediated transformation and biolistics. The future use of transformed trees on a commercial basis depends upon thorough evaluation of the potential environmental and public health risk of the modified plants, transgene stability over a prolonged period of time and the effect of the gene on tree and fruit characteristics. We studied the stability of expression and the effect on resistance to the fire blight disease of the lytic protein gene, attacin E, in the apple cultivar 'Galaxy' grown in the field for 12 years. Results Using Southern and western blot analysis, we compared transgene copy number and observed stability of expression of this gene in the leaves and fruit in several transformed lines during a 12 year period. No silenced transgenic plant was detected. Also the expression of this gene resulted in an increase in resistance to fire blight throughout 12 years of orchard trial and did not affect fruit shape, size, acidity, firmness, weight or sugar level, tree morphology, leaf shape or flower morphology or color compared to the control. Conclusion Overall, these results suggest that transgene expression in perennial species, such as fruit trees, remains stable in time and space, over extended periods and in different organs. This report shows that it is possible to improve a desirable trait in apple, such as the resistance to a pathogen, through genetic engineering, without adverse alteration of fruit characteristics and tree shape.

    Abstract The aim of the study was to disclose a realistic estimate of primary open-angle glaucoma treatment, follow-up costs, and patients’ monthly glaucoma-economic burden in an ophthalmology hospital in Mexico City. Prospective survey of 462 primary open-angle glaucoma patients from 2007 to 2012 was carried out. Costs from visits, glaucoma follow-up studies, laser, and glaucoma surgical procedures were obtained from hospital pricings. Education, employment, and monthly income were interrogated. Total cost was divided into hypotensive treatment cost, nonpharmacologic treatment cost (laser and surgeries), and follow-up studies and consults. Average wholesale price for drugs analyzed was obtained from IMS Health data; monthly cost was calculated using: Monthly cost  = ([average wholesale price/number of drops per eye dropper] × number of daily applications) × 30 days. Patients were classified according to their glaucoma severity, and data were analyzed based on monthly income (average annual exchange rate: 12.85 Mexican pesos = 1 USD). The mean age was 70 ± 10 years, women = 81%, elementary school = 39%, and unemployed = 53%. Low-income group = 266 patients (57%), 146 with mild glaucoma; moderate-income group = 176 patients (38%), 81 with mild glaucoma; high-income group = 20 patients (4.3%), 10 with mild glaucoma. Patients’ monthly average economic burden in glaucoma treatment: low-income patients = 61.5%, moderate-income patients = 19.5%, and high-income patients = 7.9%. Glaucoma-economic burden is substantial not only for health systems, but for the family and the patient. Therefore, screening plans for earlier diagnosis, and health policies that lessen the cost of disease management and increase adherence to treatment, and reduce the prevalence of blindness attributed to glaucoma are essential. These would improve quality of life, reduce personal and national expenditure, and help increase national

    Purpose:In Iran,the most common cause of injuries and the second leading cause of deaths are traffic accidents,and those problems impose a substantial financial burden on the society.This study aims to determine traffic accident mortality trends and their epidemiologic characteristics in the Kermanshah province,west of Iran.Methods:In a cross sectional study,road traffic fatality data from 2004 to 2013 were analyzed to determine the epidemiological pattern of traffic accident mortality.Trend assessment was performed to ascertain the decreasing or increasing status.Chi-square and one-way analysis of variance (ANOVA) tests,as well as Poisson regression were used to determine the significance of the data in time.Data were analyzed using Excel and statistical package of SPSS version 19.Results:Out of 5110 people that died in traffic accidents,4024 (78.7%) were males.The state of accidents indicated that 404 (43.8%) female pedestrians died as a result of car crashes,and 1330 (41.4%) males died because of car collisions.1554 (31.9%) deaths happened to pedestrians and 1556 (32.1%) to vehicle drivers,and the rest belonged to vehicle passengers.Head trauma was the cause of death for as much as 3400 (69.9%) cases.Fatal crashes in which pedestrians were involved mostly occurred between the hours 13:00 to 15:00,while the time for vehicle drivers was between 16:00 to 18:00.2882 people (59.1%) died before reaching to health care facilities.Traffic crash mortality trend for pedestrians follows a linear pattern with a gentle downward slope,but the trend shows various swings when it comes to vehicle drivers.Conclusion:The number of traffic crash deaths from 2004 to 2013 indicates a decreasing trend in two groups of road users:vehicle drivers and car occupants.This can be due to some interventions such as modification of traffic rules and enhancement of police control which has been implemented in recent years.Moreover,more attention should be paid to promote the

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

    The purpose of this study is to determine the profile of the demand for paediatric neurology care in a Spanish tertiary hospital over the past 20 years. We studied epidemiological data, reasons for consultation, diagnoses and complementary tests from all patients examined by our Paediatric Neurology Unit in its 20 years of service (from May 1990 to March 2010). We also reviewed data from patients whose first visit took place within the last five years (2005-2010) and compared them to data obtained from a prior study carried out in this Unit from 1990 to 1995. To compare the first 5 years (group 1) with the last 5 years (group 2), we calculated confidence intervals, P<.05, for the frequency distribution (%) in each category. Main reasons for consultation and principal diagnoses for the 12726 patients evaluated in the 20-year period, as well as results from group 1 (2046 patients) and group 2 (4488 patients) corresponding to first and the last 5 years of activity respectively, are presented with their confidence intervals in a series of tables. Variations in the reasons for consultation, diagnoses and complementary tests over time reflect changes determined by medical, scientific and social progress, and organisational changes specific to each hospital. This explains the difficulty of comparing different patient series studied consecutively, which are even more pronounced between different hospitals. Copyright © 2012 Sociedad Española de Neurología.

    Dyslexia is a common learning difficulty. As a result of SS' own experiences as a medical student with dyslexia, we have been researching and teaching on this topic for the past two years. Here, we present twelve tips for teaching medical students with dyslexia. These are gathered from our personal experiences and research, discussions with other educators, and wider literature on the topic. This article aims to shed some light on dyslexia, and also to make practical suggestions. Teaching students with dyslexia should not be a daunting experience. Small changes to existing methods, at minor effort, can make a difference - for example, adding pastel colors to slide backgrounds or avoiding Serif fonts. These tips can help educators gain more insight into dyslexia and incorporate small, beneficial adaptations into their teaching.

    BACKGROUND: Antimicrobial resistance is a concern that is challenging the ability to treat common infections. Surveillance of antimicrobial use in pediatric acute care institutions is complicated because the common metric unit, the defined daily dose, is problematic for this population. OBJECTIVE: During a four-year period in which no specific antimicrobial stewardship initiatives were conducted, pediatric antimicrobial use was quantified using days of therapy (DOT) per 100 patient days (PD) (DOT/100 PD) at the Alberta Children’s Hospital (Calgary, Alberta) for benchmarking purposes. METHODS: Drug use data for systemic antimicrobials administered on wards at the Alberta Children’s Hospital were collected from electronic medication administration records. DOT were calculated and rates were determined using 100 PD as the denominator. Changes over the surveillance period and subgroup proportions were represented graphically and assessed using linear regression. RESULTS: Total antimicrobial use decreased from 93.6 DOT/100 PD to 75.7 DOT/100 PD (19.1%) over the 2010/2011 through to the 2013/2014 fiscal years. During this period, a 20.0% increase in PD and an essentially stable absolute count of DOT (2.9% decrease) were observed. Overall, antimicrobial use was highest in the pediatric intensive care and oncology units. DISCUSSION: The exact changes in prescribing patterns that led to the observed reduction in DOT/100 PD with associated increased PD are unclear, but may be a topic for future investigations. CONCLUSION: Antimicrobial use data from a Canadian acute care pediatric hospital reported in DOT/100 PD were compiled for a four-year time period. These data may be useful for benchmarking purposes.

    The results of kidney transplantation have improved significantly in the last decade with patient and graft survival rates that range from 92% to 95%. We analyzed the clinical results in the last 100 consecutive patients with a follow-up of 6-42 months at our institution. We also made a general evaluation of the patients before surgery as candidates for transplantation and divided them into 3 groups (good, moderate, and poor). We had 8 living donors and 92 cadaveric kidney transplantation cases. Principal cause of donor death was cerebrovascular disease accounting for 64%. Mean age of recipients was 55.1 ± 12.9 years with a total of 65 males. Currently there are 96 functioning allografts. During this 3-year period, 2 patients suffered graft loss and 2 patients died with a functioning allograft. We studied whether there were statistically significant differences in renal function (Modification of Diet in Renal Disease Study Equation [MDRD]) at 12 months and at last visit with respect to the evaluation of recipient as candidate for renal transplantation. Our observations suggest great improvement of early results of renal transplantation in recent years, including complex cases. In this 3-year period we had a patient survival rate of 98% and a graft survival rate of 96% of cases. Further dedicated prospective studies that aim to evaluate or to propose possible recipient-related predictors for kidney transplantation outcomes in different populations are needed.

    Objective To examine long-term prognosis of a zero coronary artery calcium (CAC) score among asymptomatic individuals and its associated warranty period. Background Emerging evidence supports CAC=0 as a favorable cardiovascular short-to-intermediate term prognostic factor. Methods 9715 individuals undergoing CAC imaging were stratified by age, Framingham risk score (FRS) and Adult Treatment Panel III (NCEP ATP III) categories and followed for a mean of 14.6 (12.9–16.8) years. Cox regression, area under the receiver operating characteristic curve (AUC) and net reclassification information (NRI) were used to assess all-cause mortality, discrimination and reclassification of CAC=0 compared with FRS and NCEP ATP III, respectively. A warranty period was pre-defined as <1% annual mortality rate. Vascular age was estimated by linear regression. Results Among 4864 individuals with baseline CAC=0 (mean age 52.1±10.8 years; 57.9% male), 229 deaths occurred. The warranty period of CAC=0 was almost 15 years for individuals at low and intermediate risk with no significant differences regarding age and gender. CAC=0 was associated with a vascular age of 1, 10, 20, and 30 years below chronologic age for individuals between 50–59, 60–69, 70–79, and ≥80 years, respectively. CAC score was the strongest predictor of death (HR 2.67, 95% CI 2.29–3.11) that enabled discrimination and consistent reclassification beyond FRS (AUC 0.71 vs. 0.64, p<0.001) and NCEP ATP III (AUC 0.72 vs. 0.64, p<0.001). Conclusions CAC=0 confers a 15-year warranty period against mortality among individuals at low-to-intermediate risk, which is unaffected by age or gender. Furthermore, in individuals considered at high-risk by clinical risk scores the presence of CAC=0 confers better survival than in individuals at low-to-intermediate risk but with any CAC.

    Background: The development in size and type of lumbar disc herniation (LDH) over time is not fully understood. Furthermore, the relationship between MRI defined LDH and clinical symptoms may not always confer with each other. This may be due to the lack of knowledge about the natural history...... of morphological changes in the related structures. In order to better understand the relationships, we investigated the following objectives. 1) the changes of LDH size through quantitative measures from MRI images taken at three time points over an eight-year period, 2) the cross-sectional associations between...... sizes of LDH and area of dural sac as well as disc height, and 3) LDH as a predictor of changes in dural sac areas and disc height after four and eight years. Methods: The study sample was assembled using a population-based cohort study of 41 year olds called “Backs on Funen Cohort”. All individuals who...

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

    Full Text Available Knowledge of the warm and cold season onset is important for the living conditions and the occupational activities of the inhabitants of a given area, and especially for agriculture and tourism. This paper presents a way to estimate the onset/end of the cold and warm period of the year, based on the sinusoidal annual variation of the Sea Surface Temperature. The method was applied on data from 8 stations of the Hellenic Navy Hydrographic Service, covering the period from 1965-1995. The results showed that the warm period starts sometime between April 28th and May 21st while it ends between October 27th and November 19th in accordance with the findings of other studies. Characteristic of the nature of the parameter used is the very low variance per station – 15 days at maximum. The average date of warm period onset is statistically the same for the largest part of the Aegean, with only one differentiation, that between Kavala and the southern stations ( Thira and Heraklion.

    The forensic autopsy is often regarded as the final medical diagnosis and expert scientific opinion in matters of death investigation, usually in the legal setting, and sometimes in the clinical setting as well. There are however limitations to what the autopsy can answer, and sometimes the circumstances surrounding a death, despite our best efforts, are simply unable to be determined. Approximately 5% of cases reportedly remain unknown after a complete autopsy. With this in mind, we sought to examine the frequency of deaths in which both the cause and manner are unknown after complete forensic examination and autopsy. Data from 452 undetermined deaths over a 5-year period were analyzed; sudden unexpected infant deaths and decomposed or skeletonized remains were excluded, as well as those with a known cause but undetermined manner of death. After exclusion of these deaths, our analysis revealed that only 0.015% of cases during this period were truly undetermined in both cause and manner of death.

    2014-01-01

    Full Text Available The phenomenon of wildfires became a global environmental problem which demands estimations of their CO2 emissions. Wildfires have deteriorated the air quality increasingly. Using available information on documented wildfires and a data set of satellite detected hot spots, total yearly emissions of CO2 in Mexico were estimated for the period 1999–2010. A map of the main vegetation groups was used to calculate total areas for every vegetation type. The yearly number of hot spots per vegetation type was calculated. Estimates of emitted CO2 in a wildfire were then accomplished by considering parameters such as: forest fuel load, vegetation type, burning efficiency, and mean burned area. The number of wildfires and total affected areas showed an annual variability. The yearly mean of affected area by a single wildfire varied between 0.2 and 0.3 km2. The total affected area during the period 1999 to 2010 was 86800 km2 which corresponds to 4.3% of the Mexican territory. Total CO2 emissions were approximately 112 Tg. The most affected vegetation types were forest and rainforest.

    Full Text Available Background/Aim. Obesity is currently considered to be the most frequent metabolic disease worldwide, not only in developed but also in developing countries. The aim of this work was to describe the development of health status in soldiers of the Armed Forces of the Czech Republic (ACR and to emphasize the markers of non-communicable diseases. Our study describes the anthropometric and biochemical parameters of a large group of Czech Army professional soldiers. Data were obtained over a period of 11 years. Methods. During the monitored period, from 1999 to 2009, military physicians carried out on the average 6,360 examinations on professional soldiers per year and monitored their health and nutritional status with the aim of preventing the risk factors of non-communicable diseases. These examinations are compulsory for all professional soldiers at the age of 25, 30, 33, and 36 years. From the age of 39, these examinations are carried out every year till the end of their career. Besides taking personal histories and carrying out standard physical examinations, blood was taken for biochemical examination. The following anthropometric parameters were monitored: body constitution using body mass index (BMI and waist circumference. Our study describes only part of the data concerning anthropometric and biochemical parameters of professional soldiers which were obtained over a period of 11 years. Results. Average BMI values in men were in the overweight range (26.5-27 kg/m2. Average values of waist circumference, however, ranged from 91.9 cm to 93.4 cm.

    OBJECTIVE To provide evidence for breast cancer prevention and control through epidemiological analysis of the incidence, mortality and survival rate of female breast cancer patients in Beijing.METHODS The female registration data in the Beijing urban area from 1982 to 2001 were retrospectively reviewed. The incidence, mortality and survival rate of female breast cancer patients were analyzed using routine and life-table statistical methods.RESULTS During the period of 1982 to 2001, there was a trend of an average annual increase of female breast cancer incidence of 4.6% in urban Beijing, and of 4.9% in the world-population standardized incidence.The epidemiological features of urban Beijing female breast cancer showed:(1)The incidence distribution of different age groups from 25 to 80 years elevated with two peaks at ages of 45~ and 70~ years; (2)There was an elevation in each age group over the last 20 years; (3)The incidence rate at ages of 35 to 64 reached 95.3/105, causing breast cancer to become the number one cancer in females. The changes in the survival rate showed the following: the 5-year observed survival rate (OSR)increased from 62.0% in 1982~1983 to 68.7% in 1987~1988, and the relative-survival rate (RSR) increased from 66.3% to 74.2%. The 10-year OSR and RSR in 1987~1988 were 60.3% and 65.1%, and at 15 years 57.5% and 61.3%, respectively. The mortality rate of breast cancer patients fluctuated from 8 to 10 per 105 population over the 20 years of study.CONCLUSION There is a trend of an annual increase in female breast cancer in Beijing. The 5-year survival is being improved gradually while the mortality remains stable. The results demonstrate that the principles of "early prevention, diagnosis and treatment" for breast cancer are effective in Beijing.

    The rate of alcohol-related emergency department (ED) presentations in young people has increased dramatically in recent decades. Injuries are the most common type of youth alcohol-related ED presentation, yet little is known about these injuries in young people. This paper describes the characteristics of alcohol-related ED injury presentations in young people over a 13-year period and determines if they differ by gender and/or age group (adolescents: 12-17 years; young adults: 18-24 years). The Queensland Injury Surveillance Unit (QISU) database collects injury surveillance data at triage in participating EDs throughout Queensland, Australia. A total of 4667 cases of alcohol-related injuries in young people (aged 12-24 years) were identified in the QISU database between January 1999 and December 2011, using an injury surveillance code and nursing triage text-based search strategy. Overall, young people accounted for 38% of all QISU alcohol-related ED injury presentations in patients aged 12 years or over. The majority of young adults presented with injuries due to violence and falls, whereas adolescents presented due to self-harm or intoxication without other injury. Males presented with injuries due to violence, whereas females presented with alcohol-related self-harm and intoxication. There is a need for more effective ways of identifying the degree of alcohol involvement in injuries among young people presenting to EDs. © 2014 Australasian Professional Society on Alcohol and other Drugs.

    An association between the dietary intake of polyphenols and human health has been shown in many epidemiological studies. Since beverages are rich sources of polyphenols, we aimed to evaluate the polyphenol intake from beverages in Japanese individuals with a focus on differences according to year, age, gender and season. More than 10,000 Japanese male and female subjects aged 1-99 y old participated in this survey every year from 1996 to 2013, and their beverage consumption and amount of polyphenol intake were calculated. Polyphenol intake from beverages in Japan showed no tendency to increase or decrease over the 18-y period, and the major sources of polyphenols in Japanese daily life were coffee and green tea. Polyphenol intake was larger in participants with higher age up to 59 y old in both male and female subjects. There was a slight difference in polyphenol intake by gender, with adult males consuming more polyphenols than adult females. Polyphenols were consumed slightly more in the winter than the summer, although the seasonal difference in polyphenol intake was not large. Our results suggest that polyphenol intake from beverages is influenced by age rather than gender or season in Japan, and may not have changed over time, at least over the 18-y period beginning in 1996 in Japan.

    Full Text Available Purpose: To explore changes in self-reported use of antacids over a 9-year period in a general population adjusted for changes in dyspeptic complaints. Methods: Data is based on two health surveys carried out in the same population in Norway in 1987-88 and 1996-97. 15,523 individuals, who responded to the questions concerning drug use in either the first survey and/or in the second survey, were included in the analyses. Generalized estimating equation (GEE was chosen for the multivariate analyses. Results: From 1987-88 to 1996-97 the proportion of antacid users in this region increased among men from 11.2% to 12.7% (40-49 years and from 11.9% to 13.4% (50-59 years, while the proportion of women using antacids decreased. The proportion of antacid users increased with age in both genders. In the same period, the frequency of self-reported dyspeptic complaints such as heartburn decreased. GEE analyses showed an overall increasing trend in antacid use over the 9 years (OR=2.0, 95% CI=1.8, 2.3 adjusted for self-reported heartburn and age. The effect of heartburn on antacid use is very strong (OR=14.6, 95% CI=12.9-16.7. The gender effect indicates that women are less likely to use antacids than men (OR=0.86, 95% CI= 0.77-0.95. Antacid use increased among those with dyspeptic complaints and also among those reporting no dyspeptic symptoms. Conclusion: The prevalence of antacid users in 1996-97 was higher than in 1987-88 adjusted for age, gender and heartburn. The proportion of antacid users increased among those with dyspeptic complaints and also among those reporting no dyspeptic symptoms.

    Outbreaks of gram-negative bacteria such as Pseudomonas aeruginosa in neonatal intensive care units (NICU) can be life-threatening to pre-term infants, which are highly susceptible to serious infections with bacteria. Forty-two ventilated neonates in the NICU of the University Children's Hospital of Tuebingen were found to be colonized (n = 40) or infected (n = 2) with P. aeruginosa within a sampling period of one year. To investigate the colonization patterns and identify potential outbreak sources, epidemiological investigations, environmental surveillance and typing by serotyping and pulsed-field gel electrophoresis of the recovered isolates were performed. The investigation demonstrated a genetically related cluster of P. aeruginosa isolates during the surveillance period in 39 neonates and a second cluster at the end of the period in two neonates. A third strain representing a genetically distinct group was found in only one patient. Environmental investigations demonstrated the presence of P. aeruginosa in the ventilation equipment of 22 patients: binasal prongs (n = 22), water reservoir (n = 9), and heater (n = 1). In one case, P. aeruginosa was found in breast milk. Other environmental investigations revealed no P. aeruginosa. Although no evidence for a unique source was found, a series of intervention steps were initiated by the NICU personnel, medical microbiologists and infection control experts. The intervention steps included reinforced training of health care staff and a change from chemical to thermal disinfection of binasal prongs. Implementation of these measurements successfully stopped the recurrent occurrence of P. aeruginosa colonization.

    Bidecadal variations are investigated in the Bering Sea, especially in the southeastern basin adjacent to the Aleutian passes, where vertical mixing may be strong because of the diurnal tide. Those variations found in this region are synchronized with the 18.6 year period nodal tidal cycle, and the temporal patterns are similar to ones around the northwestern subarctic Pacific near the Kuril Straits reported by a previous study. Salinity and density in the upper layer are high in the periods when the diurnal tide is strong. In the intermediate layer, layer thickness is large, and isopycnal potential temperature and apparent oxygen utilization are low in the same periods. It is shown that these variations are consistent with the patterns expected from the nodal modulation of vertical mixing, and a simple two-dimensional model, assuming a balance between anomalous vertical mixing and advection of anomaly by the mean current, succeeds to some extent in explaining the variations of the upper layer salinity and isopycnal temperature and apparent oxygen utilization in the intermediate layer.

    Full Text Available Background: Primary Thyroid Lymphoma (PTL is uncommon, accounting for only 5% of thyroid neoplasms and less than 2.5 to 7% of extranodal lymphomas. The study aims to analyze the histopathological findings and to correlate it with clinical features. Methods: This study includes cases of PTL received in the department of pathology in a tertiary care center, Kerala, south India over a period of 5 years. Patient details and follow up data were obtained by communication with treating doctors and reviewing the hospital records. All cases had a minimum follow up of 6 months. Results: 15 cases of PTL were diagnosed over the five year period. In total 72 cases of extranodal lymphomas were diagnosed, thus forming 20.83% of extra nodal lymphomas. Lymphocytic thyroiditis was present in 93.3%. Most of the cases were Extranodal Marginal Zone B Cell Lymphoma (EMZBCL and Diffuse Large B Cell Lymphoma (DLBCL. Conclusion: It is important to consider the diagnosis of primary thyroid lymphoma in patients presenting with an enlarging neck mass especially with the history of Hashimoto's thyroiditis. Random microscopic foci of DLBCL or small areas of MZBL could be overlooked examination or missed with limited sampling. The distinction between MZBL and DLBCL in the thyroid is clinically significant. [Int J Res Med Sci 2015; 3(3.000: 579-582

    Objective. There is a paucity of research on substance use disorders (SUDs) in the elderly psychiatric population. This study examines SUDs in a geriatric psychiatry inpatient service over a 10-year period. Methods. Data from 1788 elderly psychiatric inpatients from a ten-year period was collected. Variables collected included psychiatric diagnoses, SUD, number of psychiatric admissions, and length of stay. Those with and without a SUD were compared using Chi-Square or Student's t-test as appropriate using SPSS. Results. 11.7% (N = 210) of patients had a SUD, and the most common substance was alcohol at 73.3% (N = 154) or 8.6% of all admissions. Other SUDs were sedative-hypnotics (11%), opiate (2.9%), cannabis (1%), tobacco (1.4%), and unspecified SUD (38.6%). SUD patients were significantly younger, divorced, male, and less frequently readmitted and had shorter lengths of stay. The most common comorbid diagnoses were major depression (26.1%), bipolar disorder (10.5%), and dementia (17.1%). Conclusions. Over 10% of psychogeriatric admissions were associated with a SUD, with alcohol being the most common. Considering the difficulties in diagnosing SUD in this population and the retrospective study design, the true prevalence in elderly psychiatric inpatients is likely higher. This study adds to sparse literature on SUD in elderly psychiatric patients. PMID:27840765

    Since the large amplitude 2007 outburst which heated its accreting, pulsating white dwarf, the dwarf nova system GW Librae has been cooling to its quiescent temperature. Our Hubble Space Telescope ultraviolet spectra combined with ground-based optical coverage during the 3rd and 4th year after outburst show that the fluxes and temperatures are still higher than quiescence (T=19,700K and 17,300K vs 16,000K pre-outburst for a log g=8.7 and d=100 pc). The K{wd} of 7.6+/-0.8 km/s determined from the CI1463 absorption line, as well as the gravitational redshift implies a white dwarf mass of 0.79+/-0.08 Msun. The widths of the UV lines imply a white dwarf rotation velocity vsin i of 40 km/s and a spin period of 209 s (for an inclination of 11 deg and a white dwarf radius of 7x10^{8} cm). Light curves produced from the UV spectra in both years show a prominent multiplet near 290 s, with higher amplitude in the UV compared to the optical, and increased amplitude in 2011 vs 2010. As the presence of this set of periods...

    The objective was to analyse the contribution of the provision at no cost to users of the 20 µg/day levonorgestrel-releasing intrauterine system (LNG-IUS) towards disability-adjusted life years (DALY) averted over a 9-year period. We analysed data from 15 030 new users of the LNG-IUS who had the device inserted at 26 Brazilian teaching hospitals between January 2007 and December 2015. The devices came from the International Contraceptive Access Foundation (ICA), a not-for-profit foundation that donates the devices to developing countries for use by low-income women who desire long-term contraception and who freely choose to use this device. Estimation of the DALY averted included live births averted, maternal morbidity and mortality, child mortality and unsafe abortions averted. A total of 15 030 women chose the LNG-IUS as a contraceptive method during the study period. Over the 9 years of evaluation, the estimated cumulative contribution of the Brazilian program in terms of DALY averted consisted of 486 live births, 14 cases of combined maternal mortality and morbidity, 143 cases of child mortality and 410 unsafe abortions. Provision of the LNG-IUS at no cost to low-income Brazilian women reduced unwanted pregnancies and probably averted maternal mortality and morbidity, child mortality and unsafe abortions. Family planning programs, policymakers and stakeholders based in low-resource settings could take advantage of the information that the provision of this contraceptive at no cost, or at affordable cost to a publicly-insured population, is an effective policy to help promote women's health. © Faculty of Sexual and Reproductive Healthcare of the Royal College of Obstetricians and Gynaecologists (unless otherwise stated in the text of the article) 2017.

    Full Text Available The aim of this study was to conduct three-year monitoring of bone mineralization (BMC and bone mineral density (BMD of adolescent girls engaged in swimming at the time of attaining the peak bone mass and of their counterparts leading a rather sedentary life, considering the intakes of calcium, phosphorus and protein, as well as the proportions among those nutrients. Two groups of girls aged 11–13 years were studied 3 times at yearly intervals: untrained controls (n = 20 and those engaged in competitive swimming (n = 20. Bone density was determined by dual-energy X-ray absorptiometry (DXA in the lumbar spine (L2 – L4. Nutrient intakes (energy, protein, calcium, phosphorus were assessed from 24-h recalls. The group of swimmers had significantly lower BMI values than the control group. No systematic, significant between-group differences were found in nutrient intake or in bone mineralization variables. Calcium intake was below the recommended norm in all subjects but mean values of bone mineralization variables (BMC, BMD steadily increased in both groups. The BMD z-scores proved negative throughout the three-year period of early adolescence in both groups of girls and that decrease was significant in swimmers. This could have been due to insufficient calcium intake as well as to inadequate calcium-to-phosphate and protein-to-calcium ratios and, when continued, might result in a decreased bone mass in adulthood.

    Herein we present the results of lobectomies performed with minimally invasive approach (video-assisted thoracic surgery - VATS) at our department during a period of five years. Between 1 January 2011 and 31 December 2015, 197 lobectomies (malignant lesions: 176 cases, benign lesions: 21 cases) were performed by three thoracic surgeons and one resident. Demographical data are as follows: 119 female/78 male, mean age: 62.4 years (range: 41-82 years). In 2011 three VATS lobectomies were performed, equaling 2.2 % of all lobectomies in that year. During the upcomig years the number of VATS lobectomies were as follows: 2012: 7 (7.3%), 2013: 13 (12%), 2014: 59 (34.5%) and 2015: 119 (68.5%). In 153 cases multiportal (78%) and in 44 cases uniportal (22%) anterior approach was performed. The resected lobes showed the following distribution: right upper: 85, mid lobe: 5, right lower: 28, left upper: 44, left lower: 34, upper bilobectomy: 1. In two cases sleeve lobectomy was performed. In 8 cases (4%) conversion to thoracotomy was needed and among the 46 uniportal procedures, 5 cases needed to be expanded into biportal approach (11%). During the study period, no intraoperative, or perioperative mortality occured. Mean operative time was 123 minutes (range: 60-135 minutes) and mean time of chest drainage was 4.3 days (range: 1-27 days). Air leakage lasting more than 7 days was present in 11.7%. Reoperation was needed in 4 cases (2%), in two cases due to bleeding, and in two cases because of expansive difficulties due to extended subcutaneous emphysema. Among the 176 VATS lobectomies performed due to malignant lesions, 169 lung cancers and 7 metastases were removed. The distribution according to the stage and histology of lung cancers was as follows: IA: 100 cases, IB: 28 cases, IIA: 17 cases, IIB: 3 cases, IIIA: 16 cases, IIIB: 1 case, and IV: 4 cases; adenocarcinoma: 128 cases, squamous cell carcinoma: 26 cases, large cell carcinoma: 3 cases, small cell lung cancer: 1 case

    Conclusion This study indicates that IL-10 promoter polymorphism variants, smoking, and alcohol consumption increase the risk of recurrence and canceration in vocal leukoplakia. Objective This prospective, clinical trial was performed to evaluate the association of interleukin (IL)-10 promoter polymorphism variants and canceration and recurrence rates in vocal leukoplakia (a pre-cancerous laryngeal carcinoma lesion) over a 2-year period. Participants and method Sixty-one post-operative patients with vocal leukoplakia were enrolled in this prospective, observational study and genotyped for the IL-10 promoter gene (IL-10-1082 A/G, -819 T/C and -592 A/C) using pyrosequencing, and responded to a 2-year follow-up survey. Recurrence and canceration rates were used to evaluate the association between the genotype variants and the clinical outcome. Results There was an increased canceration rate in the variant genotype group compared to that in the normal genotype group in the 2-year follow-up period (18.4% vs 0%, p-value = 0.038). Compared with the non-smoker group, the smoker group had a higher recurrence rate of vocal leukoplakia (29.3% vs 5%, p-value =0.044). Likewise, the recurrence rate in the alcohol consumption group was also higher (30.6% vs 8%, p-value =0.034). The percentage of cancerization in the alcohol consumption group was significantly higher than that in the non-alcohol consumption group (19.4% vs 0%, p-value =0.035).

    Full Text Available Background: Adverse Cutaneous Drug Reactions (ACDRs account for 3% of all hospitalizations. The spectrum of drug reactions can be varied from mild to life threatening forms. Since the diagnosis of ACDR is purely clinical, early and prompt identification and withdrawal of drug (s is life saving for the patient. Aim and Objectives: To study the epidemiological and common clinical patterns and drugs causing ACDRs in tertiary care hospital of Goa Medical College, Goa over a 6 year period. Material and Methods:This was a retrospective study conducted over a period of 6 years. The medical records were analyzed for demographic profiles, morphology of drug eruptions, common groups of drugs involved, presence of co-morbid factors, systemic and mucosal involvement, common haematological abnormalities encountered, time interval between drug intake and onset of rash and mortality. Results: Our study population had 256 patients and the age group of 21-40 years was commonly affected. Maculopapular rash followed by angioedema were the commonest morphology of drug rash patterns encountered in our study. The time interval between consumption of drugs and onset of ACDR varied with interval of 1-7 days being the commonest group in having 158 (61.7% patients. Antibiotics followed by anticonvulsants and antiretrovirals were the commonest groups of drugs causing ACDR. We found that significant proportion of our patients had haematological, renal and hepatic system involvement. Conclusion: Early identification and withdrawal of the culprit drug remains the cornerstone in prevention of mortalities in ACDRs. A prior knowledge about the reaction patterns and common offending drugs in the population by the treating physician cannot be overemphasized.

    Full Text Available Abstract Background Bacterial meningitis remains a source of substantial morbidity and mortality in childhood. During the last decades gradual changes have been observed in the epidemiology of bacterial meningitis, related to the introduction of new polysaccharide and conjugate vaccines. The study presents an overview of the epidemiological patterns of acute bacterial meningitis in a tertiary children 's hospital during a 32-year period, using information from a disease registry. Moreover, it discusses the contribution of communicable disease registries in the study of acute infectious diseases. Methods In the early 1970s a Meningitis Registry (MR was created for patients admitted with meningitis in Aghia Sofia Children's Hospital in Athens. The MR includes demographic, clinical and laboratory data as well as treatment, complications and outcome of the patients. In 2000 a database was created and the collected data were entered, analyzed and presented in three chronological periods: A (1974–1984, B (1985–1994 and C (1995–2005. Results Of the 2,477 cases of bacterial meningitis registered in total, 1,146 cases (46.3% were classified as "probable" and 1,331 (53.7% as "confirmed" bacterial meningitis. The estimated mean annual Incidence Rate (IR was 16.9/100,000 for bacterial meningitis, 8.9/100,000 for Neisseria meningitidis, 1.3/100,000 for Streptococcus pneumoniae, 2.5/100,000 for Haemophilus influenzae type b (Hib before vaccination and 0.4/100,000 for Hib after vaccination. Neisseria meningitis constituted the leading cause of childhood bacterial meningitis for all periods and in all age groups. Hib was the second most common cause of bacterial meningitis before the introduction of Hib conjugate vaccine, in periods A and B. The incidence of bacterial meningitis due to Streptococcus pneumoniae was stable. The long-term epidemiological pattern of Neisseria meningitidis appears in cycles of approximately 10 years, confirmed by a significant

    The impact of the 18.6 year period modulation of the localized strong tidal mixing on the annual mean sea surface temperature (SST) in the open North Pacific Ocean is analyzed in a numerical experiment using an ocean general circulation model. Oscillatory SST anomalies induced in this model move eastward along the boundary between the subarctic and the subtropical gyres from the western boundary to the central Pacific in about 10 years, with a speed slower than that of the surface currents. Anomalous currents in the upper 300 m play an important role in inducing SST anomalies. These anomalous currents are coupled to subsurface density anomalies and could be related to eastward moving, low-mode (second or higher), baroclinic long Rossby waves. These results suggest that the 18.6 year modulation of localized strong tidal mixing can influence large-scale SST and/or heat flux, and thus climate, as a result of remote impacts associated with changes in the mid-depth density structure, induced locally where mixing is strong, that move horizontally into the open ocean.

    Full Text Available PURPOSE: To identify the frequency and causes of uveitis leading to visual impairment in patients referred to the Low Vision Service - Department of Ophthalmology - UNIFESP, over a twenty years period. METHODS: In a retrospective study, medical records of 5,461 patients were reviewed. Data from the first clinical evaluation at the Low Vision Service were collected, patient's age, gender and cause of visual impairment were analyzed. Patients with uveitis had their chart reviewed for anatomical classification and clinical diagnosis. RESULTS: The mean age of the patients referred to the Low Vision Service was 42.86 years and the mean age of patients with uveitis diagnosis was 25.51 years. Retinal disorders were the most common cause of visual impairment (N=2,835 patients; 51.9% followed by uveitis (862 patients, 15.7%. Uveitis was posterior in 792 patients (91.9% of uveitis and toxoplasmosis was the most common diagnosis (765 patients, 88.7%. CONCLUSIONS: In our study, uveitis represents the second cause of visual impairment in patients referred for visual rehabilitation and toxoplasmic retinochoroiditis was the most common clinical diagnosis. It affects a young working age population with a relevant social and economic impact, but the early diagnosis and treatment can improve the quality of life of these patients.

  12. Evaluation of the eight-year period of compulsory measles vaccination in the Czech Socialist Republic (CSR).

    The object of the study is the evaluation of a more than 8-year period of compulsory vaccination against measles in the CSR. So far, a total of 1,850,000 children have been vaccinated. A pronounced decrease has been achieved in morbidity while mortality and lethality reached zero values as early as in 1973. Changes occur in the epidemiological characteristic of measles manifested primarily by the shift of the age distribution of notified cases into older age groups, by continuous prolongation of interepidemic intervals and by gradual disappearances of typical seasonal incidence. Regular immunological surveys have become the most efficient tools in epidemiological surveillance of this infection and in monitoring the vaccination programme. The results of immunological surveys indeed led to the introduction in 1975 of so-called second vaccination compulsory for children starting the first year of school attendance. Up to the present, a total of 24,000 cases of measles have been recorded in children vaccinated earlier, i.e., 1.5% of the total of vaccinated children. It can be expected that measles as a mass disease will be eliminated from the territory of the CSR in the next few years.

Participants aged 2–45 years (n = 126 were randomised at a single centre in the Philippines to receive TDV vaccinations at months 0, 3–4, and 12 (TDV–TDV–TDV group or licensed typhoid vaccination (TyVi at month 0 and TDV at months 3–4 and 12 (TyVi–TDV–TDV group. Dengue antibodies were measured annually (plaque reduction neutralisation test. Participants with suspected dengue underwent laboratory testing. No safety concerns were reported throughout the study. Six dengue cases were virologically confirmed, but assessed as non-severe dengue disease. Geometric mean titres throughout the follow-up period remained 2- to 4-fold higher than at baseline for all serotypes, ages and study groups. Approximately 10% of participants annually were exposed to wild-type dengue, which contributed to persistently higher titres compared with non-infected participants. In conclusion, TDV appears to have good safety and persistence of antibodies over five years.

    Purpose High intensity interval training (HIIT) has been proposed as a time-efficient format of exercise to reduce the chronic disease burden associated with sedentary behaviour. Changes in oxygen utilisation at the local tissue level during an acute session of HIIT could be the primary stimulus for the health benefits associated with this format of exercise. The recovery periods of HIIT effect the physiological responses that occur during the session. It was hypothesised that in sedentary individuals, local and systemic oxygen utilisation would be higher during HIIT interspersed with active recovery periods, when compared to passive recovery periods. Methods Twelve sedentary males (mean ± SD; age 23 ± 3 yr) completed three conditions on a cycle ergometer: 1) HIIT with passive recovery periods between four bouts (HIITPASS) 2) HIIT with active recovery periods between four bouts (HIITACT) 3) HIITACT with four HIIT bouts replaced with passive periods (REC). Deoxygenated haemoglobin (HHb) in the vastus lateralis (VL) and gastrocnemius (GN) muscles and the pre-frontal cortex (FH), oxygen consumption (VO2), power output and heart rate (HR) were measured continuously during the three conditions. Results There was a significant increase in HHb at VL during bouts 2 (p = 0.017), 3 (p = 0.035) and 4 (p = 0.035) in HIITACT, compared to HIITPASS. Mean power output was significantly lower in HIITACT, compared to HIITPASS (p < 0.001). There was a significant main effect for site in both HIITPASS (p = 0.029) and HIITACT (p = 0.005). There were no significant differences in VO2 and HR between HIITPASS and HIITACT. Conclusions The increase in HHb at VL and the lower mean power output during HIITACT could indicate that a higher level of deoxygenation contributes to decreased mechanical power in sedentary participants. The significant differences in HHb between sites indicates the specificity of oxygen utilisation. PMID:27677081

    Papillary squamous cell carcinoma (PSCC) is a distinct histological subtype of oral squamous cell carcinoma (SCC), described in both dogs and man. In dogs, PSCC has long been considered a malignant oral tumour of very young animals, but it has recently been reported to occur in adult dogs as well. The aim of this study was to describe the major clinicopathological characteristics of canine oral PSCC (COPSCC). Twelve dogs diagnosed with COPSCC were included in this retrospective study (1990-2012). The majority (75%) of the dogs were >6 years of age (median age 9 years). All tumours were derived from the gingiva of dentate jaws, with 66.7% affecting the rostral aspects of the jaws. The gross appearance of the lesions varied, with one having an intraosseous component only. The majority (91.7%) of the tumours were advanced lesions (T2 and T3), but no local or distant metastases were noted. Microscopically, two patterns were seen: (1) invasion of bone forming a cup-shaped indentation in the bone or a deeply cavitating cyst within the bone (cavitating pattern), (2) histologically malignant growth, but lack of apparent bone invasion (non-cavitating pattern). The microscopical appearance corresponded to imaging findings in a majority of cases, with cavitating forms presenting with a cyst-like pattern of bone loss or an expansile mass on imaging and non-cavitating forms showing an infiltrative pattern of bone destruction on imaging. These features suggest two distinct biological behaviours of COPSCC.

    We describe 3 outbreaks of brucellosis investigated by our Occupational Health Service in a 1-year period. Two of these outbreaks, with 2 cases each, occurred in 2 cheese factories and the third outbreak, also with 2 cases, occurred in a cattle laboratory belonging to the local government. In both cheese factories, numerous opportunities for the workers to become infected were found. The greatest risk was considered to be the area for unloading milk, while failure to use personal protection equipment by workers, deficiencies in the laboratories, and the lack of effective separation between areas were also potential risk factors. In the cattle laboratory, we found at least 13 major risk factors that could allow brucellosis transmission. In Spain, there is a substantial risk of Brucella infection in laboratories or dairy factories and current preventive measures are ineffective.

    Using a nationally representative sample of 5,150 Dutch students who have been followed over a 6-year period, the presence of the Matthew effect was investigated for general language skills. The analyses do not reveal unmistakable evidence for the supposition that the rich get richer and the poor poorer. On the contrary, in schools with low starting levels students make more progress than in schools with higher starting levels. On the other hand, the analyses do show a widening gap between students with well educated and poorly educated parents. The gap between delayed and accelerated students was found to increase as well, but the initial disadvantage of boys was found to disappear.

    A linear accelerator (linac) takes a leading role in radiation therapy. A linac consists of complicated main parts and systems and it is required that highly accurate operational procedures should be maintained. Operational failure occurs for various reasons. In this report, the failure occurrences of one linac over a ten year period were recorded and analyzed. The subject model was a MEVATRON77 DX67 (Siemens, Inc). The failure rate for each system, the form classification of the contents of failure, the operation situation at the time of failure, and the average performance life of the main parts were totaled. Moreover, the relation between the number of therapies that patients received (operating efficiency) and the failure rate within that number and the relation between environment (temperature and humidity) and the failure rate attributed to other systems were analyzed. In this report, irradiation interruption was also included with situations where treatment was unable to begin in total for the number o...

    Acute respiratory viral infections are a major cause of morbidity during early childhood in developing countries. Human rhinoviruses are the most frequent cause of upper respiratory tract infections in humans, which can range in severity from asymptomatic to clinically severe disease. In this study we collected 4170 nasopharyngeal swabs from patients hospitalised with influenza-like illness in two Cambodian provincial hospitals between 2007 and 2010. Samples were screened for 18 respiratory viruses using 5 multiplex PCRs. A total of 11.2% of samples tested positive for human rhinoviruses (HRV). VP4/2 and VP1 regions were amplified and sequenced to study the distribution of rhinoviruses genotypes and species in Cambodia during this three-year period. Five novel genotypes, 2 species A, 2 species B and 1 species C were identified based on VP1 sequences. Co-infections with other viruses were demonstrated. Copyright © 2015 Elsevier B.V.

    Mycobacterial interspersed repetitive-unit-variable-number tandem repeat typing alone was used to investigate the genetic lineages among 361 Mycobacterium tuberculosis strains circulating in Ireland over a two-year period, 2010 and 2011. The majority of isolates, 63% (229\\/361), belonged to lineage 4 (Euro-American), while lineages 1 (Indo-Oceanic), 2 (East-Asian) and 3 (East-African–Indian) represented 12% of isolates each (42\\/361, 45\\/361, and 45\\/361, respectively). Sub-lineages Beijing (lineage 2), East-African–Indian (lineage 1) and Delhi\\/central-Asian (lineage 3) predominated among foreign-born cases, while a higher proportion of Euro-American lineages were identified among cases born in Ireland. Eighteen molecular clusters involving 63 tuberculosis (TB) cases were identified across four sub-lineages of lineage 4. While the mean cluster size was 3.5 TB cases, the largest cluster (involving 12 Irish-born cases) was identified in the Latin American–Mediterranean sub-lineage. Clustering of isolates was higher among Irish-born TB cases (47 of 63 clustered cases), whereas only one cluster (3\\/63) involved solely foreign-born individuals. Four multidrug-resistant cases identified during this period represented lineages 2 and 4. This study provides the first insight into the structure of the M. tuberculosis population in Ireland.

    Full Text Available Diarrhea is the most common gastrointestinal symptom in HIV-infected patients. The incidence and severity of diarrhea increase with progression of the immune defi ciency. In the literature, 30-60% of the patients with diarrhea among HIV-infected individuals remain without specified etiological agent. The aim of this article is to present the incidence of enterocolitis among hospitalized HIV-infected patients over a 3-year period and the degree of etiological clarifi cation of the cause. The results of our analyses showed that 63% of the hospitalized HIV-infected patients for this period were with enterocolitis. Only in 30% of these patients etiological agent was isolated. The reasons for this are mainly financial constraints and, therefore, virological investigations and further endoscopic and histopathological examination of the patients with negative for bacteria and parasites stool samples, were not performed. In the cases with isolated pathogen, an etiological treatment was carried out in parallel with highly active antiretroviral therapy, while in unsubstantiated cases an empirical treatment was carried out. Advanced immune defi ciency was associated with more severe course and worse prognosis of the enterocolitis. The treatment with highly active antiretroviral therapy, which leads to improvement of the immune status of the patients, is essential for the output of enterocolitis in HIV-infected patients.

    Badland landscapes are known to be the main sediment sources in the upper Llobregat basin and particularly in the small Vallcebre research basins (Eastern Pyrenees). The dynamics of these badlands is dominated by physical weathering during winter and by water erosion during intense rainstorms in summer. Nevertheless, as these landscapes represent a small fraction of the basin area, their role as runoff source is only relevant when the basin is dry, but it becomes less important during major rainfall events under wet conditions. Thus, there is a temporal uncoupling between runoff and sediment supply that results in events with a large variety of sediment concentration - discharge relationships at the gauging stations, as well as sediment deposition and erosion phases in the stream channels. The main aim of this work is to analyse the relevance and renewal times of the sediment stored in the stream channels in the Ca l'Isard sub-basin (1.32 km2). Information on stream discharge and suspended sediment loads was taken from a 15-year record at the gauging station, whereas badland erosion for the same period was simulated using the soil erosion model KINEROS2. The model was calibrated and validated using 3-year sediment yield data obtained using containers provided with slot divisors in a 1,240 m2 elementary badland catchment. Other qualitative observations were also used for validation. The results demonstrated that there was a low correlation between badland erosion volumes and stream sediment loads at the event scale; the first were well correlated with rainfall intensities whereas the latter were better correlated with total event precipitations and stream discharges. Badland erosion was simulated as null for some events with large stream sediment loads because de model did not simulate any runoff on the hillslopes. Stream sediment transport was more compulsive than badland erosion, as 90% of the sediment exported from the basin was produced by only 21% of the events

    The Swedish Nuclear Fuel and Waste Management Co (SKB) is currently investigating the Forsmark and Oskarshamn areas for possible localisation of a repository for spent nuclear fuel. Important components of the investigations are characterizations of the land surface ecosystems in the areas with respect to hydrological and biological processes, and their implications for the fate of radionuclide contaminants entering the biosphere from a shallow groundwater contamination. In this study, we simulate water balance and carbon turnover processes in forest ecosystems representative for the Forsmark and Oskarshamn areas for a 100-year period using the ecosystem process model CoupModel. The CoupModel describes the fluxes of water and matter in a one-dimensional soil-vegetation-atmosphere system, forced by time series of meteorological variables. The model has previously been parameterized for many of the vegetation systems that can be found in the Forsmark and Oskarshamn areas: spruce/pine forests, willow, grassland and different agricultural crops. This report presents a platform for further use of models like CoupModel for investigations of radionuclide turnover in the Forsmark and Oskarshamn area based on SKB data, including a data set of meteorological forcing variables for Forsmark 1970-2004, suitable for simulations of a 100-year period representing the present day climate, a hydrological parameterization of the CoupModel for simulations of the forest ecosystems in the Forsmark and Oskarshamn areas, and simulated carbon budgets and process descriptions for Forsmark that correspond to a possible steady state of the soil storage of the forest ecosystem.

    Background Human metapneumovirus (hMPV) was discovered by scientists in the Netherlands as a novel respiratory virus in 2001 and had been found in children with acute respiratory tract infections (ARTI) in China. The objective of this study was to determine the importance of hMPV infection in children in Beijing and the genotypes of the circulating virus by the surveillance during a four-consecutive-year period.Methods Clinical specimens collected from children with ARTI from January 2006 to December 2009 were tested for hMPV by RT-PCR using primers targeting the matrix (M) gene, followed by genotyping of hMPV directly from positive samples by diplex PCR with primers for glycoprotein (G) genes. Sequence analysis was used for genotyping of those un-typable samples. Common respiratory viruses in these clinical specimens were tested by virus isolation and antigen detection, in addition to hMPV detection.Results Of 4730 tested specimens, 191 (4.0%) were positive for hMPV and 62.8% of 191 were identified as genotype A. The positive rate of hMPV from hospitalized patients was higher than that from outpatients each year. Most of hMPV positive children were under five years old. The peak of hMPV activity mostly occurred in late spring and overlapped with or followed that of respiratory syncytial virus (RSV) and followed by parainfluenza virus 3. Of hMPV infected cases,68.6% were lower respiratory tract infection, among which 79.4% were hospitalized, and upper respiratory tract infection was diagnosed for 31.4% of hMPV infected children. The 9.4% of hMPV positive samples were found to co-exist with other respiratory viruses.Conclusions hMPV was an important pathogen for ARTI in pediatric patients, especially those under five years old.Both genotypes A and B circulated simultaneously in Beijing.

    Patients with a first episode of psychosis (FEP) display a broad range of metabolic risk factors related to the development of diverse medical comorbidities. Initial stages of these disorders are essential in understanding the increased vulnerability of developing cardiometabolic disturbances, associated with a reduced life expectancy. This study aimed to evaluate the metabolic profile of a cohort of patients with a FEP and its evolution during a two year follow-up, as well as the factors that influence the changes in their metabolic status. 16 participating centers from the PEPs Project recruited 335 subjects with a FEP and 253 matched healthy controls, aged 9-35years. We investigated a set of anthropometric measures, vital signs and laboratory data obtained from each participant over two years in a prospective, naturalistic study. From the beginning of the study the FEP group showed differences in the metabolic profile compared to the control group, together with a progressive worsening in the major part of the analyzed variables during the follow-up period, with higher rates of obesity and metabolic syndrome. Certain risk factors were related to determinate clinical variables such as male gender, the presence of affective symptoms or an early onset or to treatment variables such as the use of antipsychotic polypharmacy, antidepressants or mood stabilizers. Our results highlight the extremely high risk of patients at early phases of schizophrenia and other psychotic disorders of developing cardiovascular comorbidity and the fast worsening of the metabolic profile during the first two years.

    Full Text Available Changes in population abundance of submerged Sphagnum denticulatum Brid. were studied in an acidic and oligotrophic lake in NW Poland over three years. Individuals were counted in a moss carpet at a depth of 2.5 m on 4 experimental plots, 1 × 1 m each, every 30 days for 36 months using the SCUBA method. PAR intensity was seasonally variable (in winter higher than in summer. Changes in water pH, conductivity, HCO3- concentration, hydration and sediment pH were statistically insignificant (p > 0.05. In the summer of the second study year the moss carpet disappeared almost completely due to a massive bloom of filamentous green algae. Periods of growth, regression and regeneration were observed in the population. The stabilisation of population size took 24 months and followed the pattern: slight fluctuations, then rapid growth and repetition of slight fluctuations. The first stage lasted nine, the second four and the third nine months. These stages took place irrespective of seasons, temperature or PAR intensity. Each rapid increase in abundance lasted about 30 days, at PAR intensity >20% and water temperature ranging from 11 to 16oC (in winter, spring or autumn. The regression stage brought about by the algal bloom started in the second year (in summer and lasted six months (until the end of January in the third year. The population regeneration began in winter (in February, water temperature 3.0oC, PAR about 20%, ice cover 0.15 m and finished with the end of spring. The population of S. denticulatum shows a repetitive pattern of abundance variations, which is seriously disturbed in summer, especially after a warm spring, by a massive bloom of filamentous green algae.

    Full Text Available Norio Yasui-Furukori, Kazuhiko Nakamura Department of Neuropsychiatry, Graduate School of Medicine, Hirosaki University, Hirosaki, Japan Abstract: Mood symptoms in bipolar disorders are significantly related to psychosocial events, and the personalized identification of symptom triggers is important. Ecological momentary assessments have been used in paper-and-pencil form to explore emotional reactivity to daily life stress in patients with bipolar disorder. However, there are few data on long-term recurrence prevention effects using ecological momentary assessments. Subjects were three outpatients with bipolar disorder who had a history of at least one admission. They recorded self-monitoring daily mood charts using a 5-point Likert scale. Paper-and-pencil mood charts included mood, motivation, thinking speed, and impulsivity. Additionally, they recorded waking time, bedtime, and medication compliance. Fewer manic or depressive episodes including admissions occurred after self-monitoring daily mood charts compared to patients’ admissions in the past 3 years. This study suggests that self-monitoring daily mood in addition to mood stabilizing medication has some effect on recurrence prevention in follow-up periods of at least 5 years. Further studies with rigorous designs and large sample sizes are needed. Keywords: bipolar disorders, recurrence, self-monitoring, ecological momentary assessments

Ecological momentary assessments have been used in paper-and-pencil form to explore emotional reactivity to daily life stress in patients with bipolar disorder. However, there are few data on long-term recurrence prevention effects using ecological momentary assessments. Subjects were three outpatients with bipolar disorder who had a history of at least one admission. They recorded self-monitoring daily mood charts using a 5-point Likert scale. Paper-and-pencil mood charts included mood, motivation, thinking speed, and impulsivity. Additionally, they recorded waking time, bedtime, and medication compliance. Fewer manic or depressive episodes including admissions occurred after self-monitoring daily mood charts compared to patients’ admissions in the past 3 years. This study suggests that self-monitoring daily mood in addition to mood stabilizing medication has some effect on recurrence prevention in follow-up periods of at least 5 years. Further studies with rigorous designs and large sample sizes are needed. PMID:28331323

    This retrospective study aimed to assess the occurrence of dental avulsions in patients with facial trauma over a 9-year period. Data was collected from records of patients attended to at the Division of Oral and Maxillofacial Surgery at Piracicaba Dental School-State University of Campinas, Piracicaba (SP), Brazil. Two hundred three patients with 387 avulsed teeth were evaluated, the central incisors being the most common teeth involved (42 % of permanent and 61 % of primary teeth). Thirty-four percent of the cases occurred on weekends, mainly on Saturdays (20 %) and the distribution in relation to the time of year was similar with slight peaks in January. The most prevalent associated dentoalveolar injury was lateral luxation (26 %) and 19 % of the patients presented with an associated facial fracture. The most common sign presented was laceration (23 %), and the main symptoms found were pain (58 %). Associated general trauma was present in 139 patients (68 %), and the most prevalent was the upper limb (41 %). Special emphasis should be given not only to diagnosis and treatment of dental avulsion but for prevention, too. An understanding of the etiology, severity, and distribution of associated traumatic injuries can help for future studies and for an effective prevention of these injuries.

    Over the last few years, incidental thyroid microcarcinoma (TMC) has become a frequent disease and its incidence in some reports is considerable. The discovery of new cases depends on the progress of the diagnostics (US scan, fine needle biopsy and cytology, CT, MRI), on the extended indications to thyroidectomy for benign disease and on the attention in pathologic examination of the specimen. The clinical evolution of this disease is not well known: in spite of a high incidence reported in some autoptic series, suggesting that this tumour could have a good prognosis, some authors report an overall incidence of up to 11% of local recurrence, metastasis and mortality. For these reasons the treatment of TMC is still controversial today. Aim of this study was to estimate the incidence and the clinico-pathological findings of TMC over a one year period of total thyroidectomies for diffuse benign thyroid diseases, and to evaluate, on the basis of the frequency of incidental microcarcinoma, if the surgical procedure of complete removal of the gland should be adopted in any case. In this series no patient had pre-operative diagnosis or tentative diagnosis of carcinoma and the incidence of TMC at the final histologic examination was 27.4%. Total thyroidectomy confirmed to be the treatment of choice for diffuse benign diseases and appeared necessary to obtain both, diagnosis and treatment of incidental TMC.

    Objectives Our aim was to provide nationwide age-standardised rates (ASR) on the usage of endovascular coiling and neurosurgical clipping for unruptured intracranial aneurysm (UIA) treatment in Germany. Setting Nationwide observational study using the Diagnosis-Related-Groups (DRG) statistics for the years 2005–2009 (overall 83 million hospitalisations). Participants From 2005 to 2009, overall 39 155 hospitalisations with a diagnosis of UIA occurred in Germany. Primary outcome measures Age-specific and age-standardised hospitalisation rates for UIA with the midyear population of Germany in 2007 as the standard. Results Of the 10 221 hospitalisations with UIA during the observation period, 6098 (59.7%) and 4123 (40.3%) included coiling and clipping, respectively. Overall hospitalisation rates for UIA increased by 39.5% (95% CI 24.7% to 56.0%) and 50.4% (95% CI 39.6% to 62.1%) among men and women, respectively. In 2005, the ASR per 100 000 person years for coiling was 0.7 (95% CI 0.62 to 0.78) for men and 1.7 (95% CI 1.58 to 1.82) for women. In 2009, the ASR was 1.0 (95% CI 0.90 to 1.10) and 2.4 (95% CI 2.24 to 2.56), respectively. Similarly, the ASR for clipping in 2005 amounted to 0.6 (95% CI 0.52 to 0.68) for men and 1.1 (95% CI 1.00 to 1.20) for women. These rates increased in 2009 to 0.8 (95% CI 0.72 to 0.88) and 1.7 (95% CI 1.58 to 1.82), respectively. We observed a marked geographical variation of ASR for coiling and less pronounced for clipping. For the federal state of Saarland, the ASR for coiling was 5.64 (95% CI 4.76 to 6.52) compared with 0.68 (95% CI 0.48 to 0.88; per 100 000 person years) in Saxony-Anhalt, whereas, ASR for clipping were highest in Rhineland-Palatinate (2.48, 95% CI 2.17 to 4.75) and lowest in Saxony-Anhalt (0.52, 95% CI 0.34 to 0.70). Conclusions To the best of our knowledge, we presented the first representative, nationwide analysis of the clinical management of UIA in Germany. The ASR increased markedly and showed

    This report examines the commercialization and use of R and D results funded by DOE's Office of Buildings and Community Systems (OBCS), an office that is dedicated to improving the energy efficiency of the nation's buildings. Three goals guided the research described in this report: to improve understanding of the factors that hinder or facilitate the transfer of OBCS R and D results, to determine which technology transfer strategies are most effective and under what circumstances each is appropriate, and to document the market penetration and energy savings achieved by successfully-commercialized innovations that have received OBCS support. Twelve successfully-commercialized innovations are discussed here. The methodology employed involved a review of the literature, interviews with innovation program managers and industry personnel, and data collection from secondary sources. Six generic technology transfer strategies are also described. Of these, contracting R and D to industrial partners is found to be the most commonly used strategy in our case studies. The market penetration achieved to date by the innovations studied ranges from less than 1% to 100%. For the three innovations with the highest predicted levels of energy savings (i.e., the flame retention head oil burner, low-E windows, and solid-state ballasts), combined cumulative savings by the year 2000 are likely to approach 2 quads. To date the energy savings for these three innovations have been about 0.2 quads. Our case studies illustrate the important role federal agencies can play in commercializing new technologies.

    Despite their clinical relevance, few studies have addressed the epidemiology of methicillin-susceptible S. aureus (MSSA). In particular, it is not clear how MSSA population structure has evolved over time and how it might have been shaped by the emergence of MRSA in the community (CA-MRSA). In the present study we have evaluated the MSSA population structure over time, its geographical distribution and relatedness with MRSA in Portugal. A total of 465 MSSA from infection and colonization, collected over a 19-year period (1992-2011) in the northern, central and southern regions of Portugal were analyzed. Isolates were characterized by spa typing and multilocus-sequence typing (MLST). Isolates with predominant spa types were characterized by pulsed-field gel electrophoresis (PFGE). Isolates relatedness was analyzed by eBURST and BURP. The 172 spa types found among the 465 MSSA were grouped into 18 spa-CC (clonal complexes). Ten clonal types were more prevalent (40 %): one major clone (ST30-t012) was present in the entire study period and all over the country and the other nine were intermittently detected over time (ST5-t002, ST8-t008, ST15-t084, ST34-t166, ST72-t148, ST1-t127, ST7-t091, ST398-t571 and ST34-t136). Interestingly, three MSSA clonal types observed only after 1996 were closely related with CA-MRSA epidemic strains (ST8-t008, ST72-t148 and ST1-t127) found currently in Portugal. The MSSA population in Portugal is genetically diverse; however, some dominant clonal types have been established and widely disseminated for almost two decades. We identified MSSA isolates that were related with emergent CA-MRSA clones found in Portugal.

    Study design Hospital-based retrospective review. Objective To describe the epidemiological characteristics and trends of traumatic spinal cord injury in Tianjin, China. Setting Tianjin Medical University General Hospital. Methods Medical records of 239 patients with traumatic spinal cord injury admitted to a general hospital from 1998 to 2009 were reviewed. Variables included gender, age, marital status, occupation, etiology, time of injury, level, and severity of injury. Epidemiological characteristics of different countries were compared. Results Over this period, the mean age of patients with traumatic spinal cord injury was 45.4 ± 14.1 years, and the male/female ratio was 4.6:1. In all, 86.2% were married. The leading cause was fall (52.3%), followed by motor vehicle collision (36.4%). The most common injury site was the cervical spinal cord, accounting for 82.0%. Incomplete tetraplegia made up for 59.4%, followed by complete tetraplegia (22.6%). Eight patients died after operation, six of whom died from respiratory complications. Conclusion The results of this study are in accordance with that of most other developing countries; falls and motor vehicle collisions were the two leading causes, but the mean age was older. Percentage of the aged with traumatic spinal cord injury was increasing. The low-falls group tended to expand over this period. All these data indicated that the preventive programs should focus on the traffic accidents and falls, and more attention should be paid to the aged for the vulnerability to low fall. PMID:21903012

  1. Global validation of the wave model WAM over a one-year period using geosat wave height data

    The high quality of wave fields simulated by the third-generation wave model WAM has already been demonstrated in various validation studies using in situ measurements as well as data from satellites as reference. However, owing to limitations of the reference data sets, the previous studies concentrated on relatively small regions or short time periods only, for which adequate measurements were available. In this paper the first global verification of the WAM model over a full 1-year period is presented. The significant wave heights hindcast for 1988 by the WAM model as implemented at the European Centre for Medium Range Weather Forecasts are compared with measurements obtained by the Geosat radar altimeter. The wave heights from WAM and Geosat show good agreement in general. However, significant regional and seasonal differences are found. The hindcast wave heights are underestimated by about 20% in large parts of the southern hemisphere and the tropical region during May-September. For the rest of the time, the agreement with Geosat data is fairly good. Together with the fact that also the rms variability of wave heights in the tropical region is clearly underestimated by WAM, this can possibly be attributed to simplifications like the neglect of atmospheric stratification effects when converting wind speeds to the wind stress fields driving WAM. Furthermore, the intercomparison indicates that low wave heights below [approx]1.5 m are generally overestimated by WAM. As it is planned to use altimeter wave heights for updating wave models in future data assimilation systems, it is quite important to have efficient quality control criteria for these data. The difference between the Geosat and WAM wave heights shows a clear dependence on the additional parameters in some cases, which must be related to quality problems of the Geosat data. Some new criteria for the rejection of incorrect Geosat data points are obtained. 16 refs., 6 figs.

    The incidence of acute kidney injury (AKI) in pregnancy is declining in developing countries but still remains a major cause of maternal and fetal morbidity and mortality. The aim of the study was to analyze the changing trends in pregnancy related AKI (PR-AKI) over a period of thirty-three years. Clinical characteristics of PR-AKI with respect to incidence, etiology and fetal and maternal outcomes were compared in three study periods, namely 1982-1991,1992-2002 and 2003-2014. The incidence of PR-AKI decreased to 10.4% in 1992-2002, from 15.2% in 1982-1991, with declining trend continuing in 2003-2014 (4.68%).Postabortal AKI decreased to 1.49% in 2003-2014 from 9.4% in 1982-1991of total AKI cases. The AKI related to puerperal sepsis increased to 1.56% of all AKI cases in 2003-2014 from 1.4% in 1982-1991. Preeclampsia/eclampsia associated AKI decreased from 3.5% of total AKI cases in 1982-1991 to 0.54% in 2003-2014. Pregnancy associated - thrombotic microangiopathy and acute fatty liver of pregnancy were uncommon causes of AKI. Hyperemesis gravidarum associated AKI was not observed in our study. Incidence of renal cortical necrosis (RCN) decreased to 1.4% in 2003-2014 from 17% in 1982-1991.Maternal mortality reduced to 5.79% from initial high value 20% in 1982-1991. The progression of PR-AKI to ESRD decreased to1.4% in 2003-2014 from 6.15% in 1982-1991. The incidence of PR-AKI has decreased over last three decades, mainly due to decrease in incidence of postabortal AKI. Puerperal sepsis and obstetric hemorrhage were the major causes of PR-AKI followed by preeclampsia in late pregnancy. Maternal mortality and incidence and severity of RCN have significantly decreased in PR-AKI. The progression to CKD and ESRD has decreased in women with AKI in pregnancy in recent decade. However, the perinatal mortality did not change throughout study period.

    Full Text Available Background: Foreign bodies in the upper digestive tube are rarely the cause of an urgent condition in gastroenterology. They usually enter the digestive tube during nutrition or by mistake. However, certain groups of the population such as convicts or psychiatric patients tend to swallow them intentionally. The authors aim was to assess the percentage of patients in which urgent endoscopic investigation revealed true foreign bodies in the upper digestive tube, to evaluate the success of endoscopic procedures and the resolution of eventual complications.Patients and methods: The study includes patients in which urgent endoscopic investigations of the upper digestive tract were performed in a 10-year period (1 January 1994 to 31 December 2003.Results: Altogether 6416 patients were investigated, mean age 59.3 years, SD ± 17.2 years, range 1–106 years, 2452 females and 3964 males. In 51 patients, 0.8% of all subjects, foreign bodies were detected in the esophagus or stomach. In these patients a total of 65 endoscopic investigations were performed, in 94% the foreign bodies were removed endoscopically (48/51 patients, in three cases the endoscopic procedures were not successful. Among the foreign bodies removed were various metal or plastic objects: coins, keys, screws, hooks, batteries, razor blades, needles, parts of kitchen, toilet or writing utensils, lighters, buttons, toys, a toothbrush as well as impacted pieces of bone. In the patients with successful endoscopic removal of the objects, no significant complications were noted. In 3 patients (3/48, 6.3% only mild hemorrhages from the region of the esophagogastric junction were observed.Conclusions: The technological development of endoscopic instruments made it possible to carry out different therapeutic procedures. The method has proved successful in removing foreign bodies from the upper digestive tube. Various factors affect the success of the procedure, the more important being adequate

    Full Text Available BACKGROUND: There are few large published studies of HIV controllers with long-term undetectable viral load (VL. We describe the characteristics and outcomes of 81 French HIV controllers. METHODS AND RESULTS: HIV controllers were defined as asymptomatic, antiretroviral-naïve persons infected ≥10 years previously, with HIV-RNA 90% of plasma samples. All available CD4 and VL values were collected at enrolment. Mixed-effect linear models were used to analyze CD4 cell count slopes since diagnosis. HIV controllers represented 0.31% of all patients managed in French hospitals. Patients infected through intravenous drug use were overrepresented (31% and homosexual men were underrepresented (26% of men relative to the ANRS SEROCO cohort of subjects diagnosed during the same period. HIV controllers whose VL values were always below the detection limit of the assays were compared with those who had rare "blips" (50% of VL values above the detection limit. Estimated CD4 cell counts at HIV diagnosis were similar in the three groups. CD4 cell counts remained stable after HIV diagnosis in the "no blip" group, while they fell significantly in the two other groups (-0.26√CD4 and -0.28√CD4/mm(3/year in the rare and frequent blip groups, respectively. No clinical, immunological or virological progression was observed in the no blip group, while 3 immunological and/or virological events and 4 cancers were observed in the blip subgroups. CONCLUSIONS: Viral blips in HIV controllers are associated with a significant decline in CD4 T cells and may be associated with an increased risk of pathological events, possibly owing to chronic inflammation/immune activation.

    To document the changes in BMI and the prevalence of overweight and obesity in young women living in poverty in a semi-urban community in Mexico. Women who had previously participated in a longitudinal research study (1997-2000) were re-assessed in 2005. Anthropometric measurements were obtained using standard procedures, and socio-demographic questionnaires were administered. Total and annual rate of change in BMI and change in the prevalence of overweight and obesity (BMI > or = 25.0 and > or =30.0) were estimated. Mean age in 2005 was 30.0 +/- 5.7 years (n = 683) and time between recruitment and follow-up was 6.4 +/- 1.0 years. Mean change in BMI was +3.6 +/- 2.7 (range -8.2 to +14.6). In 2005, 500 (73.2%) women were overweight, up from 263 (38.5%) in the original assessment. The prevalence of obesity tripled over the follow-up period (from 9.8% to 30.3%). The mean annual rate of change in BMI was +0.6 (+/-0.4). After adjustment for age and parity at baseline, an annual rate of change of BMI above the sample median (>0.5) was associated with lower levels of formal education. The annual increase in the prevalence of overweight and obesity in this sample is double that which was reported at a national level in Mexico. An understanding of the determinants of this rapid increase among the women living in poverty in Mexico is urgently needed.

    Full Text Available Introduction: Most of the studies conducted in Iranian medical schools are carried out as student's theses on which a lot of time and energy is spent. The purpose of the present study was to determine the characteristics of medical student's theses at Kermanshah University of Medical Sciences during a five year period (2004-2008.Methods: In this descriptive, cross-sectional study a checklist consisting of 21 questions was designed. The data were gathered from all medical student's theses during 2004-2008 (n=189 using a consensus method of data collection. Data were analyzed by descriptive statistics using SPSS software.Results: In terms of type, most of the theses were descriptive cross-sectional (33.3%, descriptive (29.1%, and descriptive-analytical (18.5%. The highest number of theses belonged to clinical psychiatry (18.5% and obstetrics and gynecology (17.5% departments. Other departments, especially basic science departments had the lowest number of theses because clinical teachers constituted 86.2% of the supervisors. The duration of the thesis completion was between 2 and 24 months. Using hospital records and inpatients files were the methods mostly used for data collection and as data sources. Furthermore, we could not find an appropriate assessment and scoring system of theses in place.Conclusion: Medical student's theses lacked appropriate quality therefore this issue should be seriously taken into consideration by educational managers.

    Despite seclusion being described as one of the most ethically- and legally-controversial management options available, it remains a widely-used clinical strategy for managing disruptive, aggressive, and violent behaviour. This study sought to determine how frequently seclusion was used, the common characteristics of those secluded and not secluded, and the degree to which the Level of Service Inventory - Revised: Screening Version (LSI-R: SV) could predict seclusion. The study was retrospective, covering the first 2 years of operation of a statewide forensic psychiatry hospital in Victoria, Australia. Data were collected from individual case files, electronic databases, and paper copies of records pertaining to violent incidents and episodes of seclusion. Eighty five (44%) of the 193 patients admitted during this period were secluded. Those secluded were significantly younger and had a more established psychiatric history. LSI-R: SV scores were significantly and positively associated with being secluded. A statistical model containing three LSI-R: SV items, along with age on admission and psychiatric history, achieved an area under the curve of 0.74. Seclusion is used on a regular basis in response to a range of different forms of aggressive behaviour of different severity. The LSI-R: SV demonstrated moderate-to-good accuracy in predicting seclusion and warrants further research using detailed prospective methodologies.

    Full Text Available Active commuting (AC to school represents a great opportunity to incorporate walking or cycling into adolescents’ everyday routine. The objective of the study was to describe changes in AC in Czech adolescents across a 10-year period in different built environments. Data from the 2001 and 2011 Czech Census of Population and Housing were used to examine the mode of transportation taken to school in 6236 adolescents. Changes in AC over time were analyzed for low and high walkable areas separately in two Czech regional cities, Olomouc and Hradec Králové. Between 2001 and 2011, the proportion of adolescents actively commuting to school decreased by 47%, from an absolute rate of 49.1% to 26%. The proportion of active commuters fell in low walkable areas by 61% and in high walkable areas by 39%. The results indicated that adolescents in 2011 were 2.7 times less (OR = 0.365, p < 0.001 likely to actively commute than in 2001. The AC behavior in Czech adolescents has a negative tendency to replicate travel-to-school patterns in adolescents previously described in more developed countries. The findings might serve as a recommendation for municipal policy.

    This study aimed at describing the profiles of Brazilian and international studies published in orthodontic journals. The sample comprised 635 articles selected from two scientific journals, i.e., Dental Press Journal of Orthodontics and American Journal of Orthodontics and Dentofacial Orthopedics, which were analyzed at three different intervals over a 10-year period (1999 - 2004 - 2009). Articles were described in terms of knowledge domain, study design, and country of origin (or state of origin for Brazilian papers). The most frequent study designs adopted in international studies were cohort (23.9%) and cross-sectional (21.7%) designs. Among Brazilian papers, cross-sectional studies (28.9%) and literature reviews (24.6%) showed greater frequency. The topics most often investigated in international articles were dental materials (17%) and treatment devices (12.4%), with the latter topic being addressed by 16% of the Brazilian publications, followed by malocclusion, with 12.6%. In all cases, the most frequent countries of origin coincided with the countries of origin of each journal. The majority of the studies analyzed featured a low level of scientific evidence. Moreover, the findings showed that journals tend to publish studies produced in their own country of origin, and that there are marked discrepancies in the number of papers published by different Brazilian states.

    OmegaWhite is a wide-field, high cadence, synoptic survey targeting fields in the southern Galactic plane, with the aim of discovering short period variable stars. Our strategy is to take a series of 39 s exposures in the g band of a 1 square degree of sky lasting 2 h using the OmegaCAM wide field imager on the VLT Survey Telescope (VST). We give an overview of the initial 4 years of data which covers 134 square degrees and includes 12.3 million light curves. As the fields overlap with the VLT Survey Telescope Halpha Photometric Survey of the Galactic plane and Bulge (VPHAS+), we currently have $ugriH\\alpha$ photometry for ~1/3 of our fields. We find that a significant fraction of the light curves have been affected by the diffraction spikes of bright stars sweeping across stars within a few dozen of pixels over the two hour observing time interval due to the alt-az nature of the VST. We select candidate variable stars using a variety of variability statistics, followed by a manual verification stage. We pres...

    There is a need to investigate the impact of different coping strategies on quality of life (QOL) of people with multiple sclerosis (MS), in order to better inform intervention programs for this population. This study evaluated the relationship between QOL and coping over a 2 year period among people with MS. Participants were 382 people with MS (144 male, 238 females) and 291 people without a neurological or other chronic illness from the general population (101 males, 190 females). People with MS experienced lower QOL than the control group in the domains of global QOL, independence, social and spiritual QOL scales, as well as the problem solving and social/emotional support coping scales. Interestingly, people with MS experienced higher psychological QOL than the general population, and higher detachment and focusing on the positive coping. Over time, people with MS demonstrated increases in their global QOL as well as in their social/emotional support coping. Women demonstrated higher levels than men of global QOL and Social/emotional support coping. The results of these findings have implications for information and intervention programs for people with MS.

    Active commuting (AC) to school represents a great opportunity to incorporate walking or cycling into adolescents' everyday routine. The objective of the study was to describe changes in AC in Czech adolescents across a 10-year period in different built environments. Data from the 2001 and 2011 Czech Census of Population and Housing were used to examine the mode of transportation taken to school in 6236 adolescents. Changes in AC over time were analyzed for low and high walkable areas separately in two Czech regional cities, Olomouc and Hradec Králové. Between 2001 and 2011, the proportion of adolescents actively commuting to school decreased by 47%, from an absolute rate of 49.1% to 26%. The proportion of active commuters fell in low walkable areas by 61% and in high walkable areas by 39%. The results indicated that adolescents in 2011 were 2.7 times less (OR = 0.365, p < 0.001) likely to actively commute than in 2001. The AC behavior in Czech adolescents has a negative tendency to replicate travel-to-school patterns in adolescents previously described in more developed countries. The findings might serve as a recommendation for municipal policy.

    Figueiredo, P, Marques, EA, and Lepers, R. Changes in contributions of swimming, cycling, and running performances on overall triathlon performance over a 26-year period. J Strength Cond Res 30(9): 2406-2415, 2016-This study examined the changes in the individual contribution of each discipline to the overall performance of Olympic and Ironman distance triathlons among men and women. Between 1989 and 2014, overall performances and their component disciplines (swimming, cycling and running) were analyzed from the top 50 overall male and female finishers. Regression analyses determined that for the Olympic distance, the split times in swimming and running decreased over the years (r = 0.25-0.43, p ≤ 0.05), whereas the cycling split and total time remained unchanged (p > 0.05), for both sexes. For the Ironman distance, the cycling and running splits and the total time decreased (r = 0.19-0.88, p ≤ 0.05), whereas swimming time remained stable, for both men and women. The average contribution of the swimming stage (∼18%) was smaller than the cycling and running stages (p ≤ 0.05), for both distances and both sexes. Running (∼47%) and then cycling (∼36%) had the greatest contribution to overall performance for the Olympic distance (∼47%), whereas for the Ironman distance, cycling and running presented similar contributions (∼40%, p > 0.05). Across the years, in the Olympic distance, swimming contribution significantly decreased for women and men (r = 0.51 and 0.68, p < 0.001, respectively), whereas running increased for men (r = 0.33, p = 0.014). In the Ironman distance, swimming and cycling contributions changed in an undulating fashion, being inverse between the two segments, for both sexes (p < 0.01), whereas running contribution decreased for men only (r = 0.61, p = 0.001). These findings highlight that strategies to improve running performance should be the main focus on the preparation to compete in the Olympic distance; whereas, in the Ironman, both

    In southern Arkansas, l3-year periodical cicadas (Magicicada spp.) were expected to emerge in late April and early May of 1998. Presence of a superabundant food source, such as periodical cicadas, may attract greater numbers of birds and more species of birds than is usually present in a particular area. Three even-aged loblolly pine (Pinus...

    Full Text Available The scientific and public awareness of hazardous photosynthetic prokaryotes (cyanobacteria/cyanoprokaryotes and especially the contamination of drinking-water reservoirs with cyanotoxins is world-wide increasing. Recently much more attention has been paid to the events and results of mass proliferation of these toxic organisms even in South-East European countries in spite of the fact that, as a rule, they are not controlled by national legislation.The present paper presents a summary of results of such studies carried out in summer-autumn periods of the last 15 years (2000-2015 in Bulgarian water bodies differing by location, morphometry and trophic status, incl. drinking water reservoirs, recreational lakes and sites of nature conservation importance. A multivariate analysis allowed to outline the distribution patterns and environmental drivers of the planktonic cyanoprokaryote assemblages in relation with the available data on the water bodies, highlighting species composition and abundance of the main taxa, including potentially toxic species. Samples analysis by HPLC-DAD and/or LC/MS, ELISA and in vitro cytotoxicity tests allowed detection of microcystins, nodularins and saxitoxins. Toxin concentration ranged between 0.1 and 26.5 µg L-1 in water samples and between 10.9 and 1070 µg g-1 (d.w. in concentrated (net samples. Despite the fact that microcystins were not found in all studied water bodies and that the recorded levels were still lower in comparison with some other European countries, the fact that cyanotoxins were detected in 16 water bodies (incl. 3 drinking water reservoirs could serve as an alert for the need of recognition of cyanotoxins as a new health risk factor in the country. Therefore, permanent monitoring with identification of toxins in water bodies at risk and activities for limitation and control of toxic blooms are urgently needed, in combination with increase of the attention to the effects of cyanotoxins on both

    Full Text Available Pyometra is the accumulation of pus in the uterine cavity, thus streaching its walls and thinning and enlarging the uterus. This change is characteristic of the senium period of life, when the uterus is atrophie with a stenotic cervical canal. It most frequently occurs as a result of secondary infection of the cancerogenic tissue of the uterus and additional stenosation and clogging up of cervical canal by a malignant process. Apart from carcinomas of the body and uterus cervix, pyometra less often can occur in other illnesses such as senile endometritis and senile colpitis. As pyometra most frequently occurs in uterine carcinomas, in detection of this state, we must think of malignancy and direct our examination to this direction. In this paper we present a patient in whom pyometra developed because she carried an intrauterine device for forty years that resulted in chronic endometritis. The main symptoms for which the patient was admited to hospital were abdominal pain and intensive suppurative vaginal excretion a month after removal of intrauterine device. The diagnosis of pyometra was made by gynaecological and ultrasound examinations, and also on the basis of gynecological and ultrasound examinations one month after chronic endometritis was confirmed. On the basis of this finding we suspected that chronic endometritis was caused by this state. By cytological, PAP and histopathological examinations of samples obtained by explorative curettage and biopsy of the uterine cervix, malignant changes were eliminated a possible cause. By laboratory analysis and bacteriological examination of the uterine cavity and vaginal excretion, inflammatory changes of the uterine mocous membrane were confirmed as a cause of the pyometra. This conditions was due to carrying the intrauterine device for more decades. The therapy consisted of dilatation of the cervical canal and evacuation of accumulated suppurative contents and irrigation of uterine cavity with 3

    Methicillin-resistant Staphylococcus aureus (MRSA) is a leading cause of infectious disease morbidity and mortality. Previous studies have confirmed the presence of S. aureus, including MRSA, on raw meat products. We investigated the prevalence and molecular epidemiology of S. aureus and MRSA in commercially-distributed antibiotic-free and conventional raw meat products (n = 3290) purchased in 8 Iowa retail stores weekly for a period of one year. Isolates were characterized using spa typing, and PCR was used to detect the presence of the Panton-Valentine leukocidin (PVL) and mecA genes. Quantitation of S. aureus on meat products was carried out one week per month. The prevalence of S. aureus on meat samples was 27.8% (913/3290). Compared to antibiotic-free meat samples, higher prevalence of both MRSA and methicillin-susceptible S. aureus (MSSA) were found in conventional meat samples. Among the S. aureus isolates, 18 were PVL-positive (1.9%) and 41 (4.5%) carried mecA. Phenotypic oxacillin resistance was observed for 17.1% (41/239) of the isolates tested, while 23% (55/239) were multi-drug resistant. A total of 132 spa types were detected from 913 contaminated meat samples. Overall, t002 was the most common spa type identified (137; 15.0%). The number of colony-forming units (CFU) per 10 g meat ranged from 2 to 517 (median: 8 CFU per 10 g of meat; mean: 28) with the highest bacterial load observed on turkey samples. These data reinforce the need to consider meat products as potential vehicles of S. aureus transmission from farm into human households, and the potential need for public health intervention programs pre and post-slaughter in meat processing facilities.

    To investigate the species distribution within the Acinetobacter calcoaceticus-Acinetobacter baumannii complex and the molecular epidemiology of A. baumannii and Acinetobacter nosocomialis, 376 Acinetobacter isolates were collected prospectively from hospitalized patients at 15 medical centres in Germany during three surveillance studies conducted over a 5-year period. Species identification was performed by molecular methods. Imipenem minimum inhibitory concentrations (MIC) were determined by broth microdilution. The prevalence of the most common carbapenemase-encoding genes was investigated by oxacillinase (OXA) -multiplex polymerase chain reaction (PCR). The molecular epidemiology was investigated by repetitive sequence-based PCR (rep-PCR; DiversiLab™). Acinetobacter pittii was the most prevalent Acinetobacter species (n = 193), followed by A. baumannii (n = 140), A. calcoaceticus (n = 10) and A. nosocomialis (n = 8). The majority of A. baumannii was represented by sporadic isolates (n = 70, 50%) that showed unique rep-PCR patterns, 25 isolates (18%) clustered with one or two other isolates, and only 45 isolates (32%) belonged to one of the previously described international clonal lineages. The most prevalent clonal lineage was international clone (IC) 2 (n = 34) and IC 1 (n = 6). According to CLSI, 25 A. baumannii isolates were non-susceptible to imipenem (MIC ≥ 8 mg/L), all of which produced an OXA-58-like or OXA-23-like carbapenemase. The rate of imipenem susceptibility among A. baumannii isolates decreased from 96% in 2005 to 76% in 2009. All other Acinetobacter isolates were susceptible to imipenem. The population structure of carbapenem-susceptible A. baumannii in Germany is highly diverse. Imipenem non-susceptibility was strongly associated with the clonal lineages IC 2 and IC 1. These data underscore the high clonality of carbapenem-resistant A. baumannii isolates.

    Bovine leukaemia virus (BLV) is associated with enzootic bovine leukosis (EBL). BLV causes malignant lymphoma and lymphosarcoma; however, most BLV infections remain clinically silent in an aleukaemic state. EBL is a notifiable disease, and official control measures include screening or monitoring, precautions at borders, control of movement inside the country, and stamping out. The objective of this study was to evaluate EBL eradication and surveillance measures in Italy from 2005 to 2012. One-hundred twenty-three outbreaks were recorded (1 January 2006 to 31 December 2012) in the National Veterinary Information System (SIMAN) on 7 November 2013. Of these, 101 had occurred in southern Italy. An outbreak usually lasted for a few days, but sometimes lasted for weeks. Some areas were subjected to normal eradication measures, whereas others were subjected to additional eradication measures as a consequence of persisting EBL outbreaks. During the study period, we noted an overall annual decrease from 0.21% in 2005 to 0.08% in 2012 in the herd prevalence rate, from 0.06% in 2005 to 0.04% in 2012 in the herd incidence rate, and from 0.027% in 2005 to 0.015% in 2012 in the animal prevalence rate. Regions officially recognised as EBL-free areas were found to have their own surveillance plans. Differences in their surveillance plans include the type of sample (serum, milk, or both), age at which the animals must be tested (12 or 24 months), and test frequency of herds (annually or every 2, 3, 4, 5, or 6 years). The eradication programme for EBL is difficult to implement in some Italian areas because of several factors such as incomplete herd registry, geographical location and socio-economic conditions of the region.

    Polypharmacy and hyperpolypharmacy are proxy indicators for inappropriate medicine use. Inappropriate medicine use in older people leads to adverse clinical outcomes. The objectives of this study were to investigate the prevalence and trends of polypharmacy and hyperpolypharmacy in older people in New Zealand from 2005 to 2013, analyzing the pharmaceutical collections maintained by the Ministry of Health. A repeated cross-sectional analysis of population-level dispensing data was conducted from January 1, 2005 to December 31, 2013. Polypharmacy and hyperpolypharmacy in individuals were defined as the use of 5-9 medicines and ≥10 medicines, respectively, dispensed concurrently for a period of ≥90 days. Differences in polypharmacy and hyperpolypharmacy between 2005 and 2013 were examined. A multinomial regression model was used to predict sociodemographic characteristics associated with polypharmacy and hyperpolypharmacy. Polypharmacy and hyperpolypharmacy were found to be higher in 2013 compared to 2005 (polypharmacy: 29.5 vs. 23.4%, ppolypharmacy and hyperpolypharmacy was higher in females, in those aged 80-84 years, in the Māori population (for polypharmacy) and the Middle Eastern, Latin American, or African population (for hyperpolypharmacy), in people living in the Southern-district health board, and in individuals with increasing deprivation. The population of New Zealand is aging and the number of older people with multiple chronic conditions is increasing. The proportion of older people exposed to polypharmacy and hyperpolypharmacy has increased in 2013 compared to 2005. Our study provides important information to alert health policy makers, researchers, and clinicians about the dire need to reduce the medication burden in older New Zealanders. © 2014 S.

  2. The twelve dimensional super (2+2)-brane

    We discuss supersymmetry in twelve dimensions and present a covariant supersymmetric action for a brane with worldsheet signature (2,2), called a super (2+2)-brane, propagating in the osp(64,12) superspace. This superspace is explicitly constructed, and is trivial in the sense that the spinorial part is a trivial bundle over spacetime, unlike the twisted superspace of usual Poincare supersymmetry. For consistency, it is necessary to take a projection of the superspace. This is the same as the projection required for worldvolume supersymmetry. Upon compactification of this superspace, a torsion is naturally introduced and we produce the membrane and type IIB string actions in 11 and 10 dimensional Minkowski spacetimes. In addition, the compactification of the twelve dimensional supersymmetry algebra produces the correct algebras for these theories, including central charges. These considerations thus give the type IIB string and M-theory a single twelve dimensional origin.

    This report examines the commercialization and use of R and D results funded by DOE's Office of Buildings and Community Systems (OBCS), an office that is dedicated to improving the energy efficiency of the nation's buildings. Three goals guided the research described in this report: to improve understanding of the factors that hinder or facilitate the transfer of OBCS R and D results, to determine which technology transfer strategies are most effective and under what circumstances each is appropriate, and to document the market penetration and energy savings achieved by successfully-commercialized innovations that have received OBCS support. Twelve successfully-commercialized innovations are discussed here. The methodology employed involved a review of the literature, interviews with innovation program managers and industry personnel, and data collection from secondary sources. Six generic technology transfer strategies are also described. Of these, contracting R and D to industrial partners is found to be the most commonly used strategy in our case studies. The market penetration achieved to date by the innovations studied ranges from less than 1% to 100%. For the three innovations with the highest predicted levels of energy savings (i.e., the flame retention head oil burner, low-E windows, and solid-state ballasts), combined cumulative savings by the year 2000 are likely to approach 2 quads. To date the energy savings for these three innovations have been about 0.2 quads. Our case studies illustrate the important role federal agencies can play in commercializing new technologies. 27 refs., 21 figs., 4 tabs.

    Recovery is a new way of life for many patients; a life without substances to alter their moods but with a major change improving the physical, psychological, and emotional stability with improved overall health outcomes. The Twelve Steps of the Alcoholics Anonymous (AA) are the foundation of the AA, describing both the necessary actions and the spiritual basis for the recovery program of the AA. The Twelve Steps of the AA provide a structure for which a patient with alcoholism may turn for an answer to their problem of alcohol use, abuse, or dependence. Copyright © 2011 Elsevier Inc.

    Continuing the project described by Kato et al. (2009, arXiv:0905.1757), we collected times of superhump maxima for 102 SU UMa-type dwarf novae observed mainly during the 2014-2015 season and characterized these objects. Our project has greatly improved the statistics of the distribution of orbital periods, which is a good approximation of the distribution of cataclysmic variables at the terminal evolutionary stage, and confirmed the presence of a period minimum at a period of 0.053 d and a period spike just above this period. The number density monotonically decreased toward the longer period and there was no strong indication of a period gap. We detected possible negative superhumps in Z Cha. It is possible that normal outbursts are also suppressed by the presence of a disk tilt in this system. There was no indication of enhanced orbital humps just preceding the superoutburst, and this result favors the thermal-tidal disk instability as the origin of superoutbursts. We detected superhumps in three AM CVn-ty...

    As an extension of the project in Kato et al. (2009, arXiv:0905.1757), we collected times of superhump maxima for 61 SU UMa-type dwarf novae mainly observed during the 2009-2010 season. The newly obtained data confirmed the basic findings reported in Kato et al. (2009): the presence of stages A-C, as well as the predominance of positive period derivatives during stage B in systems with superhump periods shorter than 0.07 d. There was a systematic difference in period derivatives for systems with superhump periods longer than 0.075 d between this study and Kato et al. (2009). We suggest that this difference is possibly caused by the relative lack of frequently outbursting SU UMa-type dwarf novae in this period regime in the present study. We recorded a strong beat phenomenon during the 2009 superoutburst of IY UMa. The close correlation between the beat period and superhump period suggests that the changing angular velocity of the apsidal motion of the elliptical disk is responsible for the variation of superh...

    2016-08-01

    Continuing the project described by Kato et al. (2009, PASJ, 61, S395), we collected times of superhump maxima for 128 SU UMa-type dwarf novae observed mainly during the 2015-2016 season and characterized these objects. The data have improved the distribution of orbital periods, the relation between the orbital period and the variation of superhumps, and the relation between period variations and the rebrightening type in WZ Sge-type objects. Coupled with new measurements of mass ratios using growing stages of superhumps, we now have a clearer and statistically greatly improved evolutionary path near the terminal stage of evolution of cataclysmic variables. Three objects (V452 Cas, KK Tel, and ASASSN-15cl) appear to have slowly growing superhumps, which is proposed to reflect the slow growth of the 3 : 1 resonance near the stability border. ASASSN-15sl, ASASSN-15ux, SDSS J074859.55+312512.6, and CRTS J200331.3-284941 are newly identified eclipsing SU UMa-type (or WZ Sge-type) dwarf novae. ASASSN-15cy has a short (˜0.050 d) superhump period and appears to belong to EI Psc-type objects with compact secondaries having an evolved core. ASASSN-15gn, ASASSN-15hn, ASASSN-15kh, and ASASSN-16bu are candidate period bouncers with superhump periods longer than 0.06 d. We have newly obtained superhump periods for 79 objects and 13 orbital periods, including periods from early superhumps. In order that future observations will be more astrophysically beneficial and rewarding to observers, we propose guidelines on how to organize observations of various superoutbursts.

    The Iberian Peninsula (IP), located in a transition area between temperate and subtropical latitudes, has marked temporal and spatial variability of precipitation between its various climatic zones. Therefore, the peninsula is particularly sensitive to climate change owing to frequent periods of precipitation deficit together with societal dependence on water. In this study, we address meteorological droughts of the peninsula between 1901 and 2010, using the Global Precipitation Climatology Center database. First, we carried out a statistical classification of the peninsula according to annual precipitation cycle. The spatiotemporal variability of droughts was evaluated using the Standardized Precipitation Index (SPI) by determining the evolution of areas affected by severe and extreme drought. Subsequently, we calculated the overall trend of precipitation and anomalies to investigate whether an observed drought increase is attributable to a decrease of precipitation or an increase of precipitation extremes. Finally, we examined periodicities of precipitation anomalies via wavelet analysis, relating these to large-scale modes such as the North Atlantic Oscillation (NAO). The results show an increase in the area affected by severe and extreme drought, particularly on Atlantic-facing slopes. The mainland areas have longer and more intense periods of drought, with an average SPI of - 0.52 and 4-month duration. Over the 110 years analyzed, we observed weak trends of annual precipitation in the extreme northwest and southern IP. However, in the last decades of the series, long periods of strong negative anomalies are seen, interspersed with years of strong positive anomalies, suggesting an increase in precipitation pattern extremes. Finally, the relationship between the NAO index and precipitation anomalies on the Atlantic seaboard is highlighted. Thus, in both series we found a 5-6-year periodicity in their first years, with a diminishing cycle period reaching a

    Agriculture in the hummocky ground moraine landscape of NE-Germany is characterized by an increase in energy crop cultivation, like maize or sorghum. Both enhance lateral C fluxes by erosion and induce feedbacks on C dynamics of agroecosystems as a result of reduced wintertime plant cover and vigorous crop growth during summer. However, the actual impact of these phenomena on the CO2-sink/-source function of agricultural landscapes, is still not clear. Therefore, the interdisciplinary project "CarboZALF" was established in Dedelow/Prenzlau (NE-Germany) in 2009. Within the field experiment CarboZALF-D, CO2 fluxes for the soil-plant systems were monitored, covering typical landscape relevant soil states in respect to erosion and deposition, like Calcic Cutanic Luvisol and Endogleyic Colluvic Regosol. Automated chamber systems, each consisting of four transparent chambers (2.5 m height, basal area 2.25 m2), were placed along gradients at both measurement sites. Monitored CO2 fluxes were gap-filled on a high-temporal resolution by modelling ecosystem respiration (Reco), gross primary productivity (GPP) and net ecosystem exchange (NEE) based on parallel and continuous measurements of the CO2 exchange, soil and air temperatures as well as photosynthetic active radiation (PAR). Gap-filling was e.g. needed in case of chamber malfunctions and abrupt disturbances by farming practice. The monitored crop rotation was corn-winter wheat (2 a), sorghum-winter triticale and alfalfa (1.5 a). In our presentation we would like to show insights from a 4 years observation period, with prounounced differences between the eroded and the colluvial soil: The Endogleyic Colluvic Regosol showed higher flux rates for Reco, GPP and NEE compared to the Calcic Cutanic Luvisol. Site-specific NEE and C-balances were positively related to soil C-stocks as well as biomass production, and generated a minor C-sink in case of the Calcic Cutanic Luvisol and a highly variable C-source in case of the

    Soil erosion still remains a persistent issue in the world, and this in spite of the efforts to ameliorate soil management systems taken into account the point of view of environmental protection against soil losses. In South Brazil water erosion is mainly associated to rainfall events with a great volume and high intensity, which are more or less evenly distributed all over the year. Nowadays, direct drilling is the most widely soil management system used for the main crops of the region. However, some crops still are grown on conventionally tilled soils, which means mainly ploughing and harrowing and less frequently chisel ploughing. In Lages-Santa Catarina State, Brazil, a plot experiment under natural rain was started in 1992 on an Inceptisol with the aim of quantifying soil and water losses. Treatments included bare and vegetated plots. The crop succession was: oats (Avena strigosa), soybean (Glycine max), vetch (Vicia sativa), maize (Zea mays), fodder radish (Raphanus sativus) and beans (Phaseolus vulgaris). Soil tillage systems investigated in this study were: i) conventional tillage (CT), ii) reduced tillage (MT), iii) no tillage (NT) under crop rotation and iv) conventional tillage on bare soil (BS). Treatments CT and BS involved ploughing plus twice harrowing, whereas MT involved chisel ploughing plus harrowing. Rainfall erosivity from January 1 1992 to December 31 2009 was calculated. Soil losses from the BS treatment along the 17 year study period were higher than 1200 Mg ha-1. Crop cover significantly reduced erosion, so that under some crops soil losses in the CT treatment were 80% lower than in the BS treatment. In turn soil losses in the MT treatment, where tillage was performed by chiselling and harrowing, were on average about 50% lower than in the CT treatment. No tillage was the most efficient soil management system in reducing soil erosion, so that soil losses in the NT treatment were about 98% lower than in the BS treatment. The three

    Water tables are dropping by approximately one meter annually throughout the North China Plain mainly due to water withdrawals for irrigating winter wheat year after year. In order to examine whether the drawdown can be reduced we calculate the net water use for an 11 year field experiment from 2003 to 2013 where six irrigated crops (winter wheat, summer maize, cotton, peanuts, sweet potato, ryegrass) were grown in different crop rotations in the North China Plain. As part of this experiment moisture contents were measured each at 20 cm intervals in the top 1.8 m. Recharge and net water use were calculated based on these moisture measurement. Results showed that winter wheat and ryegrass had the least recharge with an average of 27 mm/year and 39 mm/year, respectively; cotton had the most recharge with an average of 211 mm/year) followed by peanuts with 118 mm/year, sweet potato with 76 mm/year, and summer maize with 44 mm/year. Recharge depended on the amount of irrigation water pumped from the aquifer and was therefore a poor indicator of future groundwater decline. Instead net water use (recharge minus irrigation) was found to be a good indicator for the decline of the water table. The smallest amount of net (ground water) used was cotton with an average of 14 mm/year, followed by peanut with 32 mm/year, summer maize with 71 mm/year, sweet potato with 74 mm/year. Winter wheat and ryegrass had the greatest net water use with the average of 198 mm/year and 111 mm/year, respectively. Our calculations showed that any single crop would use less water than the prevalent winter wheat summer maize rotation. This growing one crop instead of two will reduce the decline of groundwater and in some rain rich years increase the ground water level, but will result in less income for the farmers.

    OmegaWhite is a wide-field, high cadence, synoptic survey targeting fields in the southern Galactic plane, with the aim of discovering short period variable stars. Our strategy is to take a series of 39 s exposures in the g band of a 1 deg2 of sky lasting 2 h using the OmegaCAM wide field imager on the VLT Survey Telescope (VST). We give an overview of the initial 4 yr of data which covers 134 deg2 and includes 12.3 million light curves. As the fields overlap with the VLT Survey Telescope Hα Photometric Survey of the Galactic plane and Bulge (VPHAS+), we currently have ugriHα photometry for ˜1/3 of our fields. We find that a significant fraction of the light curves have been affected by the diffraction spikes of bright stars sweeping across stars within a few dozen of pixels over the two hour observing time interval due to the alt-az nature of the VST. We select candidate variable stars using a variety of variability statistics, followed by a manual verification stage. We present samples of several classes of short period variables, including: an ultra compact binary, a DQ white dwarf, a compact object with evidence of a 100 min rotation period, three CVs, one eclipsing binary with an 85 min period, a symbiotic binary which shows evidence of a 31 min photometric period, and a large sample of candidate δ Sct type stars including one with a 9.3 min period. Our overall goal is to cover 400 deg2, and this study indicates we will find many more interesting short period variable stars as a result.

    This paper examines trends in the nursing labour market in Canada over a period of dramatic fluctuations in hospital expenditures. We add to previous analysis that covered the period 1991-1996 and use Census data from 2001 to examine the relationship between hospital expenditure and nurse labour force participation. We find that shifts in labour force participation over the period 1991-2001 had a significant impact on the nursing supply in Canada. Individuals who were trained in nursing but were working outside the profession in 1996 because of budgetary reductions and layoffs in hospitals had largely been reabsorbed back into nursing jobs by 2001. Our analysis provides further empirical evidence that the labour force participation among individuals trained in nursing is driven to a large extent by demand-side factors.

    To analyze the clinical features and course of Kawasaki disease in central Tunisia. We studied retrospectively 14 cases of children with Kawasaki disease collected in tunisian center during three years (2000-2002). The study is about 11 boys and 3 girls (sex - ratio: 3.6/1) aged from 6 months to 8 years (mean age : 4 years). Twelve patients had at least 5 diagnostic criteria of the illness, the two others had an incomplete form. We noted cardiac complications in seven patients treated belatedly, beyond 10 days of progression, because of atypical clinical presentations. All patients had all a middle caliber coronary aneurysm that was complicated by a thrombus in three cases, associated with pericarditis and minimal mitral insufficiency in a case and with a cardiac rhythm disturbance (block of branch) in another case. Besides the cardiac complications, several other visceral manifestation could be noted: joint symptoms in five cases, GI tract symptomes in three cases, neuro-meningeal in two cases and urinary trad symptomes in two other cases. Specific treatment (aspirin with antiinflammatory dose and intravenous immune globulin (IVIG)) has been instituted in all patients. The course was favorable for 12 patients with fast regression of clinical manifestation and progressive normalisation of biologic values. Two patients did not respond to the initial IVIG treatment, and had to recense received an additional course of IGIV but without clinical nor biological improvement. These two patients were treated with corticosteroids. Cardiac lesions disappeared completely in all patients even for those with thrombosis and in patients with IVIG-resistant Kawasaki disease. Only one patient had kept neurologic sequellae: aphasia, bevavioral problemes and partial epilepsy. Kawasaki disease is not rare in our region. Incomplete or atypical presentations are frequent and are a source of diagnostic delay. Coronary aneurysm due to the delay of treatment often regresses even in patients

    Continuing the project described by Kato et al. (2009a, arXiv:0905.1757), we collected times of superhump maxima for SU UMa-type dwarf novae mainly observed during the 2012-2013 season. We found three objects (V444 Peg, CSS J203937 and MASTER J212624) having strongly positive period derivatives despite the long orbital period (Porb). By using the period of growing stage (stage A) superhumps, we obtained mass ratios for six objects. We characterized nine new WZ Sge-type dwarf novae. We made a pilot survey of the decline rate of slowly fading part of SU UMa-type and WZ Sge-type outbursts. The decline time scale was found to generally follow the expected Porb^(1/4) dependence and WZ Sge-type outbursts also generally follow this trend. There are some objects which show slower decline rates, and we consider these objects good candidates for period bouncers. We also studied unusual behavior in some objects, including BK Lyn which made a transition from an ER UMa-type state to the novalike (standstill) state in 2013...

    Kumar, Syam [Malabar Cancer Centre, Thalassery, Kannur, Kerala (India); George, Anu [Dr NGP Arts and Science College, Coimbatore, Tamil Nadu (India)

    2014-06-15

    Purpose: To evaluate the 2D array for radiation response for a period of 2 years. Methods: 45 VMAT plans already treated and quality assured before 2 years, 1.5 years and 1 year were selected for the study. Quality assurances of the plans were done using 2D array combined with Octavius phantom. Verification plans were recalculated without changing any parameters in Eclipse 10.0 TPS using the AAA algorithm. Response of 2D array to the plans treated before 2 years, 1.5 years and 1 year where evaluated. The results were analyzed using the Gamma analysis method with the standard gamma passing criteria of 3mm distance to agreement (DTA) and 3% dose difference (DD). Results: All the plans evaluated passed the gamma analysis with a percentage greater than 95, except for three cases. Higher gamma passing criteria where observed for all the analyzed plans, when analysis done before 2 years, 1.5 years and 1 year. The standard deviation of ± 1.38, ± 1.40,± 0.97 where observed between the plans when verification plans did before 2 years, 1.5 years and 1 year respectively. Same set of plans shows a standard deviation of ± 0.70, ± 1.36, and ± 1.18, when analysis done recently. A significance difference in response of the array when analysis done recently for the verification plans treated and quality assured before 2 years.This indicates a slightly reduced response of 2D array towards radiation response as the array gets older. Conclusion: It is found that 2D array shows a reduced response against radiation detection over a period of years. An onsite calibration of the instrument is recommended before the measurements. A dose correction factor can be applied if necessary to the results if the radiation response and efficiency of the array is very poor.

    Since wetland construction projects are becoming more commonplace, meaningful follow-up studies are needed to evaluate how these systems change over time. To that end, the objective of our study was to examine the temporal changes in plant community composition and water chemistry in two constructed wetlands. We investigated two wetland sites that were constructed in 2003 in northern Otsego County, NY, a county that is largely dominated by agriculture. Site 1 was previously an active cow pasture and site 2 was previously a wet meadow surrounded by agricultural fields. No active plant introduction was made during the construction; however, both sites were located in areas with many remnant wetlands and were connected to through-flowing streams. In 2004 (Year 1) and 2010 (Year 7), the plant community composition and nitrogen retention were assessed. We found that both sites experienced site-wide declines in plant species richness, including the loss of upland and facultative upland species and the unanticipated loss of facultative wetland and some obligate species. We propose that high water levels, which, at their maximum depth were >1.5 m deeper than in Year 1, maintained by landowners in the years after the initial survey, may have been responsible for the unexpected loss of wetland species. We also found that site 1 exhibited considerable nitrogen retention in both Year 1 and Year 7; however, N concentrations were low at site 2 in both years.

    Continuing the project described in Kato et al. (2009, PASJ, 61, S395), we collected times of superhump maxima for SU UMa-type dwarf novae mainly observed during the 2012-2013 season. We found three objects (V444 Peg, CSS J203937, and MASTER J212624) having strongly positive period derivatives despite the long orbital period (Porb). By using the period of growing stage (stage A) superhumps, we obtained mass ratios for six objects. We characterized nine new WZ Sge-type dwarf novae. We made a pilot survey of the decline rate in the slowly fading parts of SU UMa-type and WZ Sge-type outbursts. The decline time scale was found to generally follow an expected P_orb^{1/4} dependence, and WZ Sge-type outbursts also generally follow this trend. There are some objects which show slower decline rates, and we consider these objects good candidates for period bouncers. We also studied unusual behavior in some objects, including BK Lyn which made a transition from an ER UMa-type state to a novalike (standstill) state in 2013, and unusually frequent occurrences of superoutbursts in NY Ser and CR Boo. We applied the least absolute shrinkage and selection operator (Lasso) power spectral analysis, which has been proven to be very effective in analyzing the Kepler data, to the ground-based photometry of BK Lyn, and detected a dramatic disappearance of the signal of negative superhumps in 2013. We suggested that the mass-transfer rates did not strongly vary between the ER UMa-type state and novalike state in BK Lyn, and this transition was less likely caused by a systematic variation of the mass-transfer rate.

    Objective To forecast the burden of symptomatic knee osteoarthritis (OA) in the elderly US population over a 10-year horizon. Design Using a computer simulation model of the natural history and management of knee OA combined with population-based data from the 2008 US Census we projected the 10-year burden of knee OA among persons 60–64 years of age. Knee OA incidence and progression rates were derived from national cohorts and calibrated to published literature. Results Using national data we estimated that 13% of 14,338,292 adults 60–64 years old have prevalent symptomatic, radiographic knee OA. Among persons surviving the next decade, 20% will have symptomatic advanced (Kellgren-Lawrence [K-L] grade 3) or end-stage (K-L 4) knee OA. Prevalence of advanced knee OA will range from 10% among non-obese to 35% among obese persons. Our estimates show that a more sensitive imaging tool, such as magnetic resonance imaging (MRI), may increase the number OA cases diagnosed by up to 94% assuming that 50% of all ‘pre-radiographic knee OA’ (K-L 1) has some evidence of cartilage degeneration seen on MRI. Conclusions Projecting new and advanced cases of knee OA among persons aged 60–64 years over the next decade creates a benchmark that can be used to evaluate population-based benefits of future disease-modifying OA drugs that are currently undergoing testing at various stages.

    Continuing the project described by Kato et al. (2009, arXiv:0905.1757), we collected times of superhump maxima for 128 SU UMa-type dwarf novae observed mainly during the 2015-2016 season and characterized these objects. The data have improved the distribution of orbital periods, the relation between the orbital period and the variation of superhumps, the relation between period variations and the rebrightening type in WZ Sge-type objects. Coupled with new measurements of mass ratios using growing stages of superhumps, we now have a clearer and statistically greatly improved evolutionary path near the terminal stage of evolution of cataclysmic variables. Three objects (V452 Cas, KK Tel, ASASSN-15cl) appear to have slowly growing superhumps, which is proposed to reflect the slow growth of the 3:1 resonance near the stability border. ASASSN-15sl, ASASSN-15ux, SDSS J074859.55+312512.6 and CRTS J200331.3-284941 are newly identified eclipsing SU UMa-type (or WZ Sge-type) dwarf novae. ASASSN-15cy has a short (~0.05...

    Full Text Available Candida species are an important cause of bloodstream infections (BSI. To evaluate the epidemiological, clinical and microbiological aspects of two cohorts {1994-1999 [period 1 (P1 ]; 2000-2004 [period 2 (P2 ]} of candidaemic patients, we performed a retrospective analysis from a laboratory-based survey. A total of 388 candidaemias were identified, with an incidence of 0.20/1,000 patient-days and a significant increase in P2 vs. P1 (0.25 vs. 0.15, p = 0.04. Cancer and prior antibiotic use were frequent and Candida albicans was the most prevalent species found (42.4%. Resistance to fluconazole was found in 2.47% of the strains. No differences were observed in the species distribution of Candida during the study periods. In the P2 cohort, there were higher prevalence of elderly individuals, cardiac, pulmonary and liver diseases, renal failure, central venous catheters and antibiotic therapy. In P1, there were higher prevalence of neurological diseases and chemotherapy. The crude mortality was 55.4%. In conclusion, our incidence rates remained high. Furthermore, the distribution pattern of Candida species and the fluconazole resistance profile remained unchanged. Moreover, we found a clear trend of higher prevalence of candidaemia among the elderly and among patients with comorbidities. Finally, it is necessary to discuss strategies for the prevention and control of Candida BSI in Brazil.

    Continuing the project described by Kato et al. (2009, PASJ 61, S395, arXiv:0905.1757), we collected times of superhump maxima for 51 SU UMa-type dwarf novae mainly observed during the 2010-2011 season. Although most of the new data for systems with short superhump periods basically confirmed the findings by Kato et al. (2009) and Kato et al. (2010, PASJ 62, 1525, arXiv:1009.5444), the long-period system GX Cas showed an exceptionally large positive period derivative. An analysis of public Kepler data of V344 Lyr and V1504 Cyg yielded less striking stage transitions. In V344 Lyr, there was prominent secondary component growing during the late stage of superoutbursts, and the component persisted at least for two more cycles of successive normal outbursts. We also investigated the superoutbursts of two conspicuous eclipsing objects: HT Cas and the WZ Sge-type object SDSS J080434.20+510349.2. Strong beat phenomena were detected in both objects, and late-stage superhumps in the latter object had an almost constan...

    Full Text Available The objective of the study was the estimation of decade variation of water content in layers with thickness of 0–10, 0–20, 0–40 and 0–60 cm of a bare light brown soil in the summer half-year (May–October in the 10-year period of 2003–2012 against the background of agro-meteorological conditions. The study was based on results of measurement of the moisture of a bare soil with the use of the TDR method, sums of atmospheric precipitations and ground water levels, conducted in the area of the Agro- and Hydrometeorology Observatory of the Wrocław University of Environmental and Life Sciences, situated in Wrocław-Swojec. The analyses revealed slight variation of mean decade values of water content in the bare soil in the summer half-year during the ten-year period under analysis. Irrespective of the thickness of the soil layer, precipitation in the 10-year period of 2003–2012 had a highly significant effect on the water content in the 2nd decade of July. In the case of soil layers with thickness down to 0–20 cm a statistically significant relation between soil water content and ground water levels was noted for the 3rd decade of May, July, and in the 3rd decade of September. In the layer with thickness of 0–60 cm the relations were statistically significant almost throughout the summer half-year, with the exception of the 1st and 2nd decades of May. Analysis of trends of mean water content of the bare soil over the 10-year period of 2003–2012 indicated their statistically significant increase in the case of most of the decades of the summer half-year only in soil layers with thickness of 0–10 and 0–20 cm.

  6. Use of age-period-cohort models to estimate effects of vehicle age, year of crash and year of vehicle manufacture on driver injury and fatality rates in single vehicle crashes in New South Wales, 2003-2010.

    Anderson, R W G; Searson, D J

    2015-02-01

    A novel application of age-period-cohort methods are used to explain changes in vehicle based crash rates in New South Wales, Australia over the period 2003-2010. Models are developed using vehicle age, crash period and vehicle cohort to explain changes in the rate of single vehicle driver fatalities and injuries in vehicles less than 13 years of age. Large declines in risk are associated with vehicle cohorts built after about 1996. The decline in risk appears to have accelerated to 12 percent per vehicle cohort year for cohorts since 2004. Within each cohort, the risk of crashing appears to be a minimum at two years of age and increases as the vehicle ages beyond this. Period effects (i.e., other road safety measures) between 2003 and 2010 appear to have contributed to declines of up to about two percent per annum to the driver-fatality single vehicle crash rate, and possibly only negligible improvements to the driver-injury single vehicle crash rate. Vehicle improvements appear to have been responsible for a decline in per-vehicle crash risk of at least three percent per calendar year for both severity levels over the same period. Given the decline in risk associated with more recent vehicle cohorts and the dynamics of fleet turnover, continued declines in per-vehicle crash risk over coming years are almost certain.

    The results showed that during the period from 1993 to 2013 on sociological subjects were protected by 82 theses. The most studied problems of military organization management processes are found in the military organization, its social structure. Less studied the economic aspects of the military organization. The study of the dynamics of military sociological research has shown that the problems of the social structure of the military organization in the long term remain valid. The economic aspects of the military organization only become relevant. It’s a natural tendency, which reflects the influence of both objective and subjective factors at the present stage of reforming the military organization.

    Ovarian pathology, although rare in children, must be included in the differential diagnosis of all girls who present with abdominal pain, an abdominal mass, or precocious puberty. To improve clinical appreciation of these lesions, the authors reviewed the presentation, evaluation, and outcome of all patients with ovarian pathology surgically treated at their institution since 1985. One hundred two girls (aged 9.8 +/- 5.5 years; range, 2 days to 20 years) underwent 106 separate ovarian operations (43 salpingo-oophorectomies, 21 oophorectomies, 33 ovarian cystectomies, and 9 ovarian biopsies). Of those presenting with acute abdominal pain (n = 59), 25 (42%) had ovarian torsion (14 associated with a mature teratoma), and only 1 (2%) had a malignant tumor. In contrast, of those presenting with an abdominal mass (n = 23), 6 (26%) had malignancies. There was no age difference between those with benign disease (9.9 +/- 5.6 years; n = 96) and those with malignant tumors (8.6 +/- 3.9 years, n = 10). Nine children had 10 operations for presumed malignant tumors (3 dysgerminomas, 2 immature teratomas with foci of yolk sac tumor, 2 juvenile granulosa cell tumors, 1 yolk sac tumor, and 1 Sertoli-Leydig cell tumor). These patients all had unilateral salpingo-oophorectomy, 4 had chemotherapy, and all are now disease free at 8.4 +/- 4.1 years follow-up. Ovarian pathology remains a rare indication for surgery in girls less than 20 years of age. Because most of these lesions are benign, ovarian-preserving operations should be performed whenever feasible. Copyright 2001 by W.B. Saunders Company.

    Time-series of Pacific Decadal Oscillation (PDO) reconstructed from tree-rings in Western North America is found to have a statistically significant periodicity of 18.6-year period lunar nodal tidal cycle; negative (positive) PDO tends to occur in the period of strong (weak) diurnal tide. In the 3rd and 5th (10th, 11th and 13rd) year after the maximum diurnal tide, mean-PDO takes significant negative (positive) value, suggesting that the Aleutian Low is weak (strong), western-central North Pacific in 30-50°N is warm (cool) and equator-eastern rim of the Pacific is cool (warm). This contributes to climate predictability with a time-table from the astronomical tidal cycle.

    Weekly samples of total suspended particles in air (TSP) were taken in south-east Beijing for a two-year period continuously from August 2005 to August 2007. Mass concentrations varied between 76 and 1028 microg m(-3) with an average concentration of 370 microg m(-3) for the whole period. The chemical composition and the mass concentration of aerosols in combination with meteorological data are reflecting specific influences of distinct aerosol sources on the pollution of Beijing's atmosphere. Lead (Pb), titanium (Ti), zinc (Zn) and copper (Cu) concentrations were chosen as indicator elements for different sources. Their amounts considerably varied over the course of the year. Element ratios, such as Pb/Ti, supported the distinction between periods of predominant geogenic or anthropogenic caused pollution. However, the interactions between aerosols from different sources are numerous and aerosol pollution still is a big and complex challenge for the sustainable development of Beijing.
