As supplementary material to Health Education programs about synthetic drugs, the authors present a historical summary on LSD, stramonium and khat. "Tripis", Special K and other synthetic pills contain these substances and are being widely used by youths. The history of these main hallucinogenic active ingredients has a strong tie to the mythology of witchcraft and witches: a historically interesting time period bearing a large amount of religious intolerance. The objective of this review is to end the belief today's youth have that they are taking new substances which have no risks.

When people with dementia are perceived as witches. Consequences for patients and nurse education in South Africa.

Mkhonto, Flora; Hanssen, Ingrid

2018-01-01

To explore and describe the link between culture and dementia care with the focus on the influence of the belief in dementia as witchcraft and people with dementia as witches. In South Africa, especially in townships and rural areas, dementia is often perceived as connected to witchcraft rather than to disease. Persons labelled as witches-mostly older women-may be bullied, ostracised, beaten, stoned, burned, even killed. One strand of findings from a larger international study is presented with in-depth qualitative interviews of one close family member and seven nurses caring for patients with severe dementia in nursing homes in Tshwane in South Africa. A hermeneutic analytic approach was used. Two main themes are found, namely "Belief in witchcraft causing fear of persons with dementia" and "Need of knowledge and education." Fear of and violence towards people with dementia are based on the belief that they are witches. Some of the nurses had also held this belief until they started working with patients with dementia. There is a great need for education both among healthcare workers and the populace. The "witch" belief prevents seeking professional help. As nursing homes tend to be private and expensive, professional dementia care is virtually unattainable for the poor. Dementia needs a more prominent place in nursing curricula. Nurses as educators need to know the local culture and language to be accepted in the various communities. They need to visit families affected by dementia, give awareness talks in churches, schools and clinics and facilitate support groups for carers of people with dementia in the local language. Improved nurses' education in gerontology and geriatric care is needed. Trained specialist nurses may work as mediators and help eradicate the witchcraft beliefs connected to severe dementia. © 2017 John Wiley & Sons Ltd.

Full Text Available The paper provides a brief outline of the historical development, principles and implementation of improvisational theatre in both the theatrical and non-theatrical context in order to present the art of improvisation as a strategy in foreign and second language acquisition. Research shows that because of the adaptability of the improvisational game structure which allows for the applicability of improvisational techniques in different contexts and with subjects of various backgrounds, improvisational theatre can be incorporated in teaching an array of subjects and topics, including English as a foreign and second language. In order to demonstrate the possible application of the improvisational strategy in English language teaching, there is a detailed description of an interdisciplinary workshop The English Anatomy of a Witch, focusing on the oral tradition of storytelling and the fairy tale as the direct product of both storytelling and improvisational practices, which contains different aspects of improvisational techniques in the classroom setting. By discussing the figure of the witch, which is anthropologically and historically present in British and American culture, the workshop aims to achieve a number of goals and objectives pertaining to both foreign and second language acquisition, the re-evaluation of the literary tradition, as well as pedagogies that foster critical and divergent thinking.

The first high-statistics and high-resolution data set for the integrated recoil-ion energy spectrum following the β^+ decay of 35Ar has been collected with the WITCH retardation spectrometer located at CERN-ISOLDE. Over 25 million recoil-ion events were recorded on a large-area multichannel plate (MCP) detector with a time-stamp precision of 2ns and position resolution of 0.1mm due to the newly upgraded data acquisition based on the LPC Caen FASTER protocol. The number of recoil ions was measured for more than 15 different settings of the retardation potential, complemented by dedicated background and half-life measurements. Previously unidentified systematic effects, including an energy-dependent efficiency of the main MCP and a radiation-induced time-dependent background, have been identified and incorporated into the analysis. However, further understanding and treatment of the radiation-induced background requires additional dedicated measurements and remains the current limiting factor in extracting a beta-neutrino angular correlation coefficient for 35Ar decay using the WITCH spectrometer.

Brogaard, Berit; Vanni, Simo; Silvanto, Juha

2013-01-01

We studied the patient JP who has exceptional abilities to draw complex geometrical images by hand and a form of acquired synesthesia for mathematical formulas and objects, which he perceives as geometrical figures. JP sees all smooth curvatures as discrete lines, similarly regardless of scale. We carried out two preliminary investigations to establish the perceptual nature of synesthetic experience and to investigate the neural basis of this phenomenon. In a functional magnetic resonance imaging (fMRI) study, image-inducing formulas produced larger fMRI responses than non-image inducing formulas in the left temporal, parietal and frontal lobes. Thus our main finding is that the activation associated with his experience of complex geometrical images emerging from mathematical formulas is restricted to the left hemisphere.

There is general consensus that adults under age 65 with acquired brain injury residing in nursing homes is inappropriate, however there is a limited evidence base on the issue. Previous research has relied heavily on third-party informants and qualitative studies have been of questionable methodological quality, with no known study adopting a phenomenological approach. This study explored the lived experiences of young adults with brain injury residing in aged care facilities. Interpretative phenomenological analysis was employed to collect and analyze data from six semi-structured interviews with participants regarding their experiences of living in nursing homes. Two themes were identified, including "Corporeal prison of acquired brain injury: broken selves" and "Existential prison of the nursing home: stagnated lives". Results illustrated that young adults with acquired brain injury can experience aged care as an existential prison in which their lives feel at a standstill. This experience was characterized by feelings of not belonging in a terminal environment, confinement, disempowerment, emptiness and hope for greater autonomy through rehabilitation. It is hoped that this study will provide relevant professionals, services and policy-makers with insight into the challenges and needs of young adults with brain injury facing these circumstances. Implications for rehabilitation This study supports the contention that more home-like and age-appropriate residential rehabilitation services for young adults with acquired brain injury are needed. As development of alternative accommodation is a lengthy process, the study findings suggest that the interim implementation of rehabilitative care in nursing homes should be considered. Taken together with existing research, it is proposed that nursing home staff may require training to deliver evidence-based rehabilitative interventions to those with brain injury. The present findings add support to the call for systemic

Downthrown traps of the NW Witch Ground Graben, UK North Sea

Energy Technology Data Exchange (ETDEWEB)

Hindle, A.D. (Texaco Ltd., London (GB))

1989-10-01

The structures drilled to-date in the NW Witch Ground Graben area have been assigned to two broad categories: upthrown traps with four-way dip closure or tilted fault blocks, generally located on the flanks of the graben; and downthrown traps with closure against a major fault, located downthrown on the main graben border-fault systems. Many of these are in fact combination traps, having upthrown fault-seal and/or stratigraphic elements. A study of trap settings has shown: the success rate for encountering hydrocarbons in upthrown traps and downthrown traps is very similar; the common belief that the footwall seal is the most critical element of a downthrown trap is questionable; modern seismic data reveals that a high proportion of unsuccessful exploratory wells were not located on a closed structure; there is a lesser chance of the reservoir being absent, or there being no migration route to the trap, in downthrown compared with upthrown structures; carboniferous sediments can be a footwall seal for a downthrown trap in one location, and a reservoir for hydrocarbons in another; the structural evolution of the Graben has been ideal for the development of downthrown traps.

No auditory experience, no tinnitus: Lessons from subjects with congenital- and acquired single-sided deafness.

Science.gov (United States)

Recent studies have adopted the Bayesian brain model to explain the generation of tinnitus in subjects with auditory deafferentation. That is, as the human brain works in a Bayesian manner to reduce environmental uncertainty, missing auditory information due to hearing loss may cause auditory phantom percepts, i.e., tinnitus. This type of deafferentation-induced auditory phantom percept should be preceded by auditory experience because the fill-in phenomenon, namely tinnitus, is based upon auditory prediction and the resultant prediction error. For example, a recent animal study observed the absence of tinnitus in cats with congenital single-sided deafness (SSD; Eggermont and Kral, Hear Res 2016). However, no human studies have investigated the presence and characteristics of tinnitus in subjects with congenital SSD. Thus, the present study sought to reveal differences in the generation of tinnitus between subjects with congenital SSD and those with acquired SSD to evaluate the replicability of previous animal studies. This study enrolled 20 subjects with congenital SSD and 44 subjects with acquired SSD and examined the presence and characteristics of tinnitus in the groups. None of the 20 subjects with congenital SSD perceived tinnitus on the affected side, whereas 30 of 44 subjects with acquired SSD experienced tinnitus on the affected side. Additionally, there were significant positive correlations between tinnitus characteristics and the audiometric characteristics of the SSD. In accordance with the findings of the recent animal study, tinnitus was absent in subjects with congenital SSD, but relatively frequent in subjects with acquired SSD, which suggests that the development of tinnitus should be preceded by auditory experience. In other words, subjects with profound congenital peripheral deafferentation do not develop auditory phantom percepts because no auditory predictions are available from the Bayesian brain.

Recent experiments testing an opponent-process theory of acquired motivation.

Science.gov (United States)

Solomon, R L

1980-01-01

There are acquired motives of the addiction type which seem to be non-associative in nature. They all seem to involve affective phenomena caused by reinforcers, unconditioned stimuli or innate releasers. When such stimuli are repeatedly presented, at least three affective phenomena occur: (1) affective contrast effects, (2) affective habituation (tolerance), and (3) affective withdrawal syndromes. These phenomena can be precipitated either by pleasant or unpleasant events (positive or negative reinforcers). Whenever we see these three phenomena, we also see the development of an addictive cycle, a new motivational system. These phenomena are explained by an opponent-process theory of motivation which holds that there are affect control systems which oppose large departures from affective equilibrium. The control systems are strengthened by use and weakened by disuse. Current observations and experiments testing the theory are described for: (1) the growth of social attachment (imprinting) in ducklings; and (2) the growth of adjunctive behaviors. The findings so far support the theory.

DNA methylation is believed to play important roles in regulating gene expression in plant growth and development. Paulownia witches' broom (PaWB) infection has been reported to be related to gene expression changes in paulownia plantlets. To determine whether DNA methylation is associated with gene expression changes in response to phytoplasma, we investigated variations in genomic DNA sequence and methylation in PaWB plantlets treated with methyl methane sulfonate (MMS) using amplified fragment length polymorphism (AFLP) and methylation-sensitive amplification polymorphism (MSAP) techniques, respectively. The results indicated that PaWB seedings recovered a normal morphology after treatment with more than 15 mg·L(-1) MMS. PaWB infection did not cause changes of the paulownia DNA sequence at the AFLP level; However, DNA methylation levels and patterns were altered. Quantitative real-time PCR (qRT-PCR) showed that three of the methylated genes were up-regulated and three were down-regulated in the MMS-treated PaWB plantlets that had regained healthy morphology. These six genes might be involved in transcriptional regulation, plant defense, signal transduction and energy. The possible roles of these genes in PaWB are discussed. The results showed that changes of DNA methylation altered gene expression levels, and that MSAP might help identify genes related to PaWB.

The phylloplane is the first contact surface between Theobroma cacao and the fungus Moniliophthora perniciosa, which causes witches' broom disease (WBD). We evaluated the index of short glandular trichomes (SGT) in the cacao phylloplane and the effect of irrigation on the disease index of cacao genotypes with or without resistance to WBD, and identified proteins present in the phylloplane. The resistant genotype CCN51 and susceptible Catongo presented a mean index of 1,600 and 700 SGT cm -2 , respectively. The disease index in plants under drip irrigation was reduced by approximately 30% compared with plants under sprinkler irrigation prior to inoculation. Leaf water wash (LWW) of the cacao inhibited the germination of spores by up to 98%. Proteins from the LWW of CCN51 were analyzed by two-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis followed by tandem mass spectrometry. The gel showed 71 spots and identified a total of 42 proteins (28 from the plant and 14 from bacteria). Proteins related to defense and synthesis of defense metabolites and involved in nucleic acid metabolism were identified. The results support the hypothesis that the proteins and water-soluble compounds secreted to the cacao phylloplane participate in the defense against pathogens. They also suggest that SGT can contribute to the resistance of cacao.

Production of hydrolytic enzymes by Trichoderma isolates with antagonistic activity against Crinipellis perniciosa, the causal agent of witches' broom of cocoa

Full Text Available Two isolates of Trichoderma, which reduce the incidence of witches'broom disease caused in cocoa by Crinipellis perniciosa, were evaluated for their potential to produce hydrolases in liquid medium. Very low or no hydrolytic activity was produced in the absence of any substrate. The activities of chitinase, N-acetylglucosaminidase, beta-1,3-glucanase, total cellulase, endoglucanase, aryl- beta-glucosidase, beta-glucosidase, protease and amylase increased dramatically within 72-120 h of growth in the presence of specific substrates. Except for N-acetylglucosaminidase and beta-glucosidase Trichoderma harzianum isolate 1051 produced the largest amounts of hydrolases. The possible involvement of these enzymes in the antagonistic interaction between Trichoderma and C. perniciosa is discussed.

Leafhoppers (Hemiptera: Auchenorrhyncha: Cicadellidae) account for more than 80% of all “Auchenorrhynchous” vectors that transmit phytoplasmas. The leafhopper populations in two almond witches'-broom phytoplasma (AlmWB) infected sites: Tanboureet (south of Lebanon) and Bourj El Yahoudieh (north of Lebanon) were surveyed using yellow sticky traps. The survey revealed that the most abundant species was Asymmetrasca decedens, which represented 82.4% of all the leafhoppers sampled. Potential phytoplasma vectors in members of the subfamilies Aphrodinae, Deltocephalinae, and Megophthalminae were present in very low numbers including: Aphrodes makarovi, Cicadulina bipunctella, Euscelidius mundus, Fieberiella macchiae, Allygus theryi, Circulifer haematoceps, Neoaliturus transversalis, and Megophthalmus scabripennis. Allygus theryi (Horváth) (Deltocephalinae) was reported for the first time in Lebanon. Nested PCR analysis and sequencing showed that Asymmetrasca decedens, Empoasca decipiens, Fieberiella macchiae, Euscelidius mundus, Thamnottetix seclusis, Balclutha sp., Lylatina inexpectata, Allygus sp., and Annoplotettix danutae were nine potential carriers of AlmWB phytoplasma. Although the detection of phytoplasmas in an insect does not prove a definite vector relationship, the technique is useful in narrowing the search for potential vectors. The importance of this information for management of AlmWB is discussed. PMID:21864154

Increasing interest is being shown in obtaining accurate predictions concerning radiation fields produced by ion beams impinging on homogeneous plane targets, the effect of this process being exothermic nuclear reactions. Previous theoretical studies made by the authors have focused on radiation fields generated by homogeneous plane disk- or ring-shaped sources, based on a unified treatment of the radiation field distribution developed by Hubbell and co-workers. In the case of an equivalent homogeneous source anisotropically emitting in non dispersive media, the Legendre polynomial series expansion method for specific emissivity function can be successfully applied when conditions for the convergence of the approximating series are satisfied. We have developed an analytical expression for the radiation field distribution around a homogeneous disk-shaped target bombarded by Witch-type distributed (in transverse plane) ion beams whose elementary areas anisotropically emit following a cos-type law in non dispersive media. Results of this investigation can be extended to various experimental situations in which the assumption of an angular omni-directional as well as of a constant space distribution of nuclear reaction emissivity over the accelerator target surface or other kinds of axi-symmetric plane sources of radiation is no longer valid.

Full Text Available Paulownia witches' broom (PaWB caused by phytoplasma might result in devastating damage to the growth and wood production of Paulownia. To study the effect of phytoplasma on DNA sequence and to discover the genes related to PaWB occurrence, DNA polymorphisms and DNA methylation levels and patterns in PaWB seedlings, the ones treated with various concentration of methyl methane sulfonate (MMS and healthy seedlings were investigated with amplified fragment length polymorphism (AFLP and methylation-sensitive amplification polymorphism (MSAP. Our results indicated that PaWB seedlings recovered a normal morphology, similar to healthy seedlings, after treatment with more than 20 mg · L-1 MMS; Phytoplasma infection did not change the Paulownia genomic DNA sequence at AFLP level, but changed the global DNA methylation levels and patterns; Genes related to PaWB were discovered through MSAP and validated using quantitative real-time PCR (qRT-PCR. These results implied that changes of DNA methylation levels and patterns were closely related to the morphological changes of seedlings infected with phytoplasmas.

Witches' broom disease (WBD) of cacao differs from other typical hemibiotrophic plant diseases by its unusually long biotrophic phase. Plant carbon sources have been proposed to regulate WBD developmental transitions; however, nothing is known about their availability at the plant-fungus interface, the apoplastic fluid of cacao. Data are provided supporting a role for the dynamics of soluble carbon in the apoplastic fluid in prompting the end of the biotrophic phase of infection. Carbon depletion and the consequent fungal sensing of starvation were identified as key signalling factors at the apoplast. MpNEP2, a fungal effector of host necrosis, was found to be up-regulated in an autophagic-like response to carbon starvation in vitro. In addition, the in vivo artificial manipulation of carbon availability in the apoplastic fluid considerably modulated both its expression and plant necrosis rate. Strikingly, infected cacao tissues accumulated intracellular hexoses, and showed stunted photosynthesis and the up-regulation of senescence markers immediately prior to the transition to the necrotrophic phase. These opposite findings of carbon depletion and accumulation in different host cell compartments are discussed within the frame of WBD development. A model is suggested to explain phase transition as a synergic outcome of fungal-related factors released upon sensing of extracellular carbon starvation, and an early senescence of infected tissues probably triggered by intracellular sugar accumulation. © The Author 2014.

Full Text Available The TOMO-ETNA experiment was performed in the framework of the FP7 “MED-SUV” (MEDiterranean SUpersite Volcanoes in order to gain a detailed geological and structural model of the continental and oceanic crust concerning Etna and Aeolian Islands volcanoes (Sicily, Italy, by means of active and passive seismic exploration methodologies. Among all data collected, some 1410 km of marine multi-channel seismic (MCS reflection profiles were acquired in the Ionian and Tyrrhenian Seas during two of the three oceanographic cruises of the TOMO-ETNA experiment, in July and November 2014, with the aim of shading light to deep, intermediate and shallow stratigraphy and crustal structure of the two above mentioned areas. The MCS sections, targeted to deep exploration, were acquired during the oceanographic cruise on board the R/V “Sarmiento de Gamboa”, using an active seismic source of 16 air-guns, for a total volume of 4340 cu. in., and a 3000 m long, 240-channels digital streamer as receiving system. High-resolution seismic profiles were instead collected through the R/V “Aegaeo”, using two smaller air-guns (overall 270 cu. in. volume and a 96 channels, 300 m long digital streamer. This paper provides a detailed description of the acquisition parameters and main processing steps adopted for the MCS data. Some processed lines are shown and preliminarily interpreted, to highlight the overall good quality and the high potential of the MCS sections collected during the TOMO-ETNA experiment.

The causal agents of witches' broom and frosty pod rot of cacao (chocolate, Theobroma cacao) form a new lineage of Marasmiaceae.

Aime, M C; Phillips-Mora, W

2005-01-01

The two most devastating diseases of cacao (Theobroma cacao)--the source of chocolate--in tropical America are caused by the fungi Crinipellis perniciosa (witches' broom disease) and Moniliophthora roreri (frosty pod rot or moniliasis disease). Despite the agricultural, socio-economic and environmental impact of these fungi, most aspects of their life cycles are unknown, and the phylogenetic relationships of M. roreri have yet to be conclusively established. In this paper, extensive phylogenetic analyses of five nuclear gene regions (28S rDNA, 18S rDNA, ITS, RPB1, and EF1-alpha) confirm that C. perniciosa and M. roreri are sister taxa that belong in the Marasmiaceae (euagarics). Furthermore, these taxa form part of a separate and distinct lineage within the family. This lineage includes the biotrophic fungi Moniliophthora perniciosa comb. nov. and M. roreri, as well as one undescribed endophytic species. The sister genera to Moniliophthora are Marasmius, Crinipellis and Chaetocalathus, which consist mainly of saprotrophic litter fungi.

Full Text Available During the 18th century, Shakespeare’s Macbeth was a source of inspiration for many painters who tried to underscore the pictorial quality of the play, especially that of Act 1, scene 3. The paper compares the interpretations offered by Henry Fuseli and Francesco Zuccarelli who were both foreign artists belonging to the Royal Academy of London. Their paintings after Act 1, scene 3, of Macbeth offer a visual representation articulated around contrast and convergence: if Fuseli remains faithful to the pivotal emotional intent, seen as the “ergon” here, Zuccarelli almost ignores it, finding a greater interest in the landscape of the scene that fills most of his pictorial space. However, the two works fuse together within the etymology of the term “ergon”, that equates with “work” or “action”. They illustrate the idea of active witchcraft through natural phenomena controlled by the three witches.

The archive effect found footage and the audiovisual experience of history

Baron, Jaimie

2013-01-01

The Archive Effect: Found Footage and the Audiovisual Experience of History examines the problems of representation inherent in the appropriation of archival film and video footage for historical purposes. Baron analyses the way in which the meanings of archival documents are modified when they are placed in new texts and contexts, constructing the viewer's experience of and relationship to the past they portray. Rethinking the notion of the archival document in terms of its reception and the spectatorial experiences it generates, she explores the 'archive effect' as it is produced across the genres of documentary, mockumentary, experimental, and fiction films. This engaging work discusses how, for better or for worse, the archive effect is mobilized to create new histories, alternative histories, and misreadings of history. The book covers a multitude of contemporary cultural artefacts including fiction films like Zelig, Forrest Gump and JFK, mockumentaries such as The Blair Witch Project and Forgotten Silve...

Microbiological profiles were analysed and compared for intra-abdominal, urinary, respiratory and bloodstream infections according to place of acquisition: community-acquired, with a separate analysis of healthcare-associated, and hospital-acquired. Prospective cohort study performed at a university tertiary care hospital over 1 year. Inclusion criteria were meeting the Centers for Disease Control definition of intra-abdominal, urinary, respiratory and bloodstream infections. A total of 1035 patients were included in the study. More than 25% of intra-abdominal infections were polymicrobial; multi-drug resistant gram-negatives were 38% in community-acquired, 50% in healthcare-associated and 57% in hospital-acquired. E. coli was the most prevalent among urinary infections: 69% in community-acquired, 56% in healthcare-associated and 26% in hospital-acquired; ESBL producers' pathogens were 10% in healthcare-associated and 3% in community-acquired and hospital-acquired. In respiratory infections Streptococcus pneumoniae was the most prevalent in community-acquired (54%) and MRSA in healthcare-associated (24%) and hospital-acquired (24%). A significant association was found between MRSA respiratory infection and hospitalization in the previous year (adjusted OR = 6.3), previous instrumentation (adjusted OR = 4.3) and previous antibiotic therapy (adjusted OR = 5.7); no cases were documented among patients without risk factors. Hospital mortality rate was 10% in community-acquired, 14% in healthcare-associated and 19% in hospital-acquired infection. This study shows that healthcare-associated has a different microbiologic profile than those from community or hospital acquired for the four main focus of infection. Knowledge of this fact is important because the existing guidelines for community-acquired are not entirely applicable for this group of patients.

Recurrent and acquired fistulae are a serious complication of congenital esophageal atresia and tracheoesophageal fistula (TEF) repair and foreign body ingestion (FBI) (e.g., button battery). We report our experience with a minimally invasive approach to recurrent and acquired TEF. Medical records of patients referred for management of recurrent and acquired TEF between 2003 and 2015 were reviewed retrospectively. Patients underwent endoscopic procedures (de-epithelization of fistulous tract and fibrin tissue adhesive-Tisseel R ) under general anesthesia. Nine children (7 male, 2 female) with age range 3months to 3years (mean 1.5year) were managed. TEF closed spontaneously in four patients, whereas in 5 patients the TEF closed after combined endoscopic procedure. Three patients required repeat endoscopic procedures. Follow-up ranged between 7months to 10years (mean 4.2years). Active observation and repeat combined endoscopic procedures are safe alternatives to open surgical repair of acquired and recurrent TEF.

This paper is an analytical study of the spatial dependency of the d-T neutron energy in the vicinity of a homogeneous tritium-occluded plane target. Close to the target, and along the path of incidence of axially symmetric deuteron beams, the transverse density of accelerated deuterons is assumed to be governed by a law approximated by the 'Witch' function. In particular circumstances, the elementary neutron emission process in non-dispersive media can be considered to be omni-directional (due consideration being paid to collision kinetics, depending upon mass and kinetic energy of particles involved in the nuclear collision, nuclear reaction energy, etc.). Consequently, analytical expressions can be considerably simplified. By applying the classical kinetic energy and momentum conservation laws to nuclear processes, a theoretical description is obtained, taking into account the exoergic character of d-T fusion reaction. A number of expressions for energetic prediction of the fast neutron field are proposed. The associated relations, involving elementary functions, can be investigated using a desk-top computer. Computationally tractable tools are of importance in the study of diverse situations such as induced reactions and activation analysis using 14 MeV neutron generators, investigations in health-physics, radiation dose measurements, nuclear medicine, damage effects, and simulation studies

Witches' broom disease of lime (WBDL) is a serious phytoplasma disease of acid lime in Oman, the UAE and Iran. Despite efforts to study it, no systemic study attempted to characterize the relationship among the associated phytoplasma, ' Candidatus Phytoplasma aurantifolia', from the three countries. This study utilized sequences of the 16S rRNA, imp and secA genes to characterize 57 strains collected from Oman (38), the UAE (9) and Iran (10). Phylogenetic analysis based on the 16S rRNA gene showed that the 57 strains shared 98.5-100 % nucleotide similarity to each other and to strains of ' Ca . P. aurantifolia' available in GenBank. The level of genetic diversity was low based on the 16S rRNA (0-0.011), imp (0-0.002) and secA genes (0-0.015). The presence of low level of diversity among phytoplasma strains from Oman, the UAE and Iran can be explained by the movement of infected lime seedlings from one country to another through trading and exchange of infected plants. The study discusses implication of the findings on WBDL spread and management.

EDF decided in 2001 to implement immediate dismantling of its first generation nuclear plants. Seven years after this decision, the physical progress of the programme is 24% and is due to reach 50 % by 2013. This paper presents the experiences acquired in the fields of organization, project and programme management, purchasing strategies and waste management. Until now, the principal works involve Brennilis (Heavy water), ChoozA (PWR) and Creys Malville (fast breeder reactor). The detailed pre-project concerning the first of the six gas graphite reactors is complete and the call for bids process has been launched. The organization to manage projects, established at the De-construction and Environment Engineering Center (CIDEN), is effective and productive. Estimates of costs and expenses are coherent, which makes the forecasts put together to finance the programme secure. CIDEN has carried out significant engineering work over the last six years, making it possible to apply for the administrative authorizations which have now been obtained or are in the process of being obtained. Technical specifications are prepared at an optimized level of detail according to a contractual policy adapted to the complexity of the operations and the sharing of risk with manufacturers. The ChoozA contractualization process has been launched and the first dismantling work has begun in the nuclear auxiliary part. The main Brennilis contract will be completed in mid- 2008 and dismantling works will restart after renewal of the decree which was cancelled in mid-2007. Treatment of sodium from Creys Malville is about to begin, leading to elimination of the sodium risk by 2013. The very low activity waste (TFA) and low to medium activity waste (FA-MA) removal chains are operational. The intermediate activity/long lived (MA-VL) waste will be stored in a facility which will be brought into operational service in 2012. The graphite storage center is due to open between 2017 and 2019

Full text: Ceratoplatanin (CP) is a secreted protein of 12.4 kDa initially identified in culture filtrates of the disease ascomycete Ceratocystis fimbriata f. sp. platani, etiological agent of the canker stain disease. CP is also the founding member of the namesake protein family, which contains fungal-secreted proteins involved in various stages of the host-fungus interaction and may act as phytotoxins or elicitors of defense response. Besides the low molecular weight, CPs have a high percentage of hydrophobic residues and share two conserved intramolecular disulfide bonds. It has been suggested that CPs have important physiological functions, including interaction with cell wall or cell membrane and manipulation of the host's defense system. Furthermore, a recent work showed that the ceratoplatanin from C. fimbriata has some degree of affinity for the saccharide 4-N-acetylglucosamine. However, its precise molecular function remains elusive. Five putative CPs have been identified in Moniliophthora perniciosa a basidiomycete fungus responsible for great economic losses in cocoa industry in the form of Witches' broom disease (WBD) , four of which had their crystal structures resolved by our group. In this work we report biophysical and functional studies on these MpCPs aiming at understanding their role and importance during the WBD progression. (author)

Clinical characteristics, etiologies, evolution, and prognostic factors of community-acquired bacterial meningitis in elderly patients are not well known. To improve this knowledge, all episodes of community-acquired bacterial meningitis were prospectively recorded and cases occurring in patients >or=65 years old were selected. During the period 1977-2006, 675 episodes in adults (aged >or=18 yr) were recorded, with 185 (27%) in patients aged >or=65 years old; 76 were male and 109 were female, with a mean age of 73 +/- 6 years (range, 65-93 yr). Causative microorganisms were Streptococcus pneumoniae 74, Neisseria meningitidis 49, Listeria monocytogenes 17, other streptococcal 9, Escherichia coli 6, Haemophilus influenzae 4, Klebsiella pneumoniae and Staphylococcus aureus 2 each, Capnocytophaga canimorsus and Enterococcus faecalis 1 each, and unknown in 20. On admission 91% had had fever, 32% were in a coma (Glasgow Coma Scale or=65 yr), who showed a higher frequency of diabetes and malignancy as underlying disease; pneumonia, otitis, and pericranial fistula as predisposing factors; and S. pneumoniae and L. monocytogenes as etiology. There were also differences in clinical presentation, complications, sequelae, and mortality. Factors independently related with mortality were age, pneumonia as a predisposing factor, coma on admission, and heart failure and seizures after therapy. Dexamethasone therapy was a protective factor. In conclusion, bacterial meningitis in elderly patients is associated with greater diagnostic difficulties and neurologic severity and more complications, as well as with increased mortality. Antiseizure prophylaxis might be useful in these patients.

In horizontal acquisitions, the post-acquisition integration of the R&D function often damages the inventive labor force and results in lower innovative productivity of acquired inventors. In this paper we study post-acquisition integration in terms of R&D team reorganization-i.e., the creation...... of new teams with both inventors of the acquiring and acquired firms-and assess the impact of this integration action in the period that immediately follows the acquisition. Drawing on social identity and self-categorization theories, we argue that R&D team reorganization increases the acquired inventors...

Should surgical novices trade their retractors for joysticks? Videogame experience decreases the time needed to acquire surgical skills.

Shane, Matthew D; Pettitt, Barbara J; Morgenthal, Craig B; Smith, C Daniel

2008-05-01

Video game experience (VGE) has been identified as a possible predictive factor for surgical skill. We hypothesized that surgical novices with previous VGE would acquire new surgical skills faster than those without. Fourth-year medical students (M4) and first-year surgical residents (PG-1) completed a survey asking about standard demographic data and previous VGE. Gamers had high VGE, defined as more than 3 h per week of videogame playing. Nongamers had little or no VGE. Both groups trained to proficiency on two tasks (AcquirePlace and Traversal) of the MIST-VR simulator, with proficiency defined as meeting previously validated criteria on two consecutive trials. The number of trials required to achieve proficiency for each task was recorded. The 26 participants included 11 M4s and 15 PG-1s: 17 males (8 gamers/9 nongamers) and 9 females (3 gamers/6 nongamers), mean age 27.8 years. There were no differences in time to proficiency between the M4 and PG-1 residents, and there were no significant differences in the relative number of gamers per gender. All participants eventually met proficiency criteria. The 11 gamers reached proficiency more quickly than the 15 nongamers (median 0 trials versus 6 trials, p = 0.01). Gamers scored lower than nongamers on their initial attempts. Women overall took longer to reach proficiency than did men (median 10 trials versus 0 trials, p = 0.002). When stratified according to VGE, female nongamers took longer to reach proficiency than male nongamers (median 11 trials versus 1 trial, p = 0.006) but among gamers, there was no difference between females and males (median 0 trials versus 0.5 trials, NS). Previous VGE shortens time to achieve proficiency on two tasks on a validated surgical simulator. The possibility that VGE may ameliorate gender differences in length of time required to acquire surgical skills should be explored further.

Full Text Available The spectrum of strategic co-operations among container lines varies from loose-knitted slot charters, liner conferences, shipping alliances, joint services and consortia, through to mergers and acquisitions (M&As. However, these forms of strategic co-operations have not always been able to achieve the intended synergetic growth resulting from the integration of resources. The Resource Based View (RBV suggests that integrating intangible resources, which are valuable, rare, inimitable and non-substitutable (VRIN, can make a significant contribution to the performance of post strategic co-operations. This research paper investigates the contribution of intangible resources to the post acquisition success six global acquisitions among container lines. The nine senior managers attached to global container lines were the main participants of this study. Five of them represented acquired container lines, four represented acquirer container lines. The paper explains their personnel experience on the processes adopts to integrate intangible resources in acquisitions.

WAYS OF ACQUIRING FLYING PHOBIA.

Schindler, Bettina; Vriends, Noortje; Margraf, Jürgen; Stieglitz, Rolf-Dieter

2016-02-01

The few studies that have explored how flying phobia is acquired have produced contradictory results. We hypothesized that classical conditioning plays a role in acquiring flying phobia and investigated if vicarious (model) learning, informational learning through media, and experiencing stressful life events at the time of onset of phobia also play a role. Thirty patients with flying phobia and thirty healthy controls matched on age, sex, and education were interviewed with the Mini-DIPS, the short German version of the Anxiety Disorders Interview Schedule (DSM-IV diagnostic criteria) and the Fear-of-Flying History Interview. Fifty Percent of patients with flying phobia and 53% of healthy controls reported frightening events in the air. There was no significant difference between the two samples. Thus there were not more classical conditioning events for patients with flying phobia. There also was no significant difference between the two samples for vicarious (model) learning: 37% of flying phobia patients and 23% of healthy controls felt influenced by model learning. The influence of informational learning through media was significantly higher for the clinical sample (70%) than for the control group (37%). Patients with flying phobia experienced significantly more stressful life events in the period of their frightening flight experience (60%) than healthy controls (19%). Frightening experiences while flying are quite common, but not everybody develops a flying phobia. Stressful life events and other factors might enhance conditionability. Informational learning through negative media reports probably reinforces the development of flying phobia. Clinical implications are discussed. © 2015 Wiley Periodicals, Inc.

Acquired neuropathies represent most of the neuropathies encountered in clinical practice. Hundreds of causes have been identified even though up to 41% of patients are still classified as idiopathic (Rajabally and Shah in J Neurol 258:1431-1436, 1). Routine evaluation relies on comprehensive medical history taking, clinical examination, nerve conduction studies and laboratory tests. Other investigations such as nerve biopsy or nerve or muscle imaging are performed in specific settings. This review focuses on recent advances in acquired neuropathies.

The basidiomycete fungus Moniliophthora perniciosa is the causal agent of Witches' Broom Disease (WBD) in cacao (Theobroma cacao). It is a hemibiotrophic pathogen that colonizes the apoplast of cacao's meristematic tissues as a biotrophic pathogen, switching to a saprotrophic lifestyle during later stages of infection. M. perniciosa, together with the related species M. roreri, are pathogens of aerial parts of the plant, an uncommon characteristic in the order Agaricales. A genome survey (1.9x coverage) of M. perniciosa was analyzed to evaluate the overall gene content of this phytopathogen. Genes encoding proteins involved in retrotransposition, reactive oxygen species (ROS) resistance, drug efflux transport and cell wall degradation were identified. The great number of genes encoding cytochrome P450 monooxygenases (1.15% of gene models) indicates that M. perniciosa has a great potential for detoxification, production of toxins and hormones; which may confer a high adaptive ability to the fungus. We have also discovered new genes encoding putative secreted polypeptides rich in cysteine, as well as genes related to methylotrophy and plant hormone biosynthesis (gibberellin and auxin). Analysis of gene families indicated that M. perniciosa have similar amounts of carboxylesterases and repertoires of plant cell wall degrading enzymes as other hemibiotrophic fungi. In addition, an approach for normalization of gene family data using incomplete genome data was developed and applied in M. perniciosa genome survey. This genome survey gives an overview of the M. perniciosa genome, and reveals that a significant portion is involved in stress adaptation and plant necrosis, two necessary characteristics for a hemibiotrophic fungus to fulfill its infection cycle. Our analysis provides new evidence revealing potential adaptive traits that may play major roles in the mechanisms of pathogenicity in the M. perniciosa/cacao pathosystem.

Musgrave, J B; Houran, J

2000-04-01

The lore surrounding the mythical Witches' Sabbat and contemporary reports of UFO abductions share three main characteristics: the use of masks, the appearance of "Men in Black," and references to flight and abduction. We review these three commonalities with particular focus on the aspect of flight and abduction. We argue that narratives of the Witches' Sabbat and UFO abductions share the same basic structure, common symbolism, and serve the same psychological needs of providing a coherent explanation for anomalous (ambiguous) experiences while simultaneously giving the experient a sense of freedom, release, and escape from the self. This pattern of similarities suggests the possibility that UFO abductions are a modern version of tales of flight to the Sabbat.

Moniliophthora perniciosa is a phytopathogenic fungus responsible for witches' broom disease of cacao trees (Theobroma cacao L.). Understanding the molecular events during germination of the pathogen may enable the development of strategies for disease control in these economically important plants. In this study, we determined a comparative proteomic profile of M. perniciosa basidiospores during germination by two-dimensional SDS-PAGE and mass spectrometry. A total of 316 proteins were identified. Molecular changes during the development of the germinative tube were identified by a hierarchical clustering analysis based on the differential accumulation of proteins. Proteins associated with fungal filamentation, such as septin and kinesin, were detected only 4 h after germination (hag). A transcription factor related to biosynthesis of the secondary metabolite fumagillin, which can form hybrids with polyketides, was induced 2 hag, and polyketide synthase was observed 4 hag. The accumulation of ATP synthase, binding immunoglobulin protein (BiP), and catalase was validated by western blotting. In this study, we showed variations in protein expression during the early germination stages of fungus M. perniciosa. Proteins associated with fungal filamentation, and consequently with virulence, were detected in basidiospores 4 hag., for example, septin and kinesin. We discuss these results and propose a model of the germination of fungus M. perniciosa. This research can help elucidate the mechanisms underlying basic processes of host invasion and to develop strategies for control of the disease.

Characterization of a protease produced by a Trichoderma harzianum isolate which controls cocoa plant witches' broom disease

Full Text Available Abstract Background Several Trichoderma strains have been reported to be effective in controlling plant diseases, and the action of fungal hydrolytic enzymes has been considered as the main mechanism involved in the antagonistic process. However, although Trichoderma strains were found to impair development of Crinipellis perniciosa, the causal agent of cocoa plant witches' broom disease, no fungal strain is available for effective control of this disease. We have then undertaken a program of construction of hydrolytic enzyme-overproducing Trichoderma strains aiming improvement of the fungal antagonistic capacity. The protease of an indian Trichoderma isolate showing antagonistic activity against C. perniciosa was purified to homogeneity and characterized for its kinetic properties and action on the phytopathogen cell wall. Results A protease produced by the Trichoderma harzianum isolate 1051 was purified to homogeneity by precipitation with ammonium sulfate followed by hydrophobic chromatography. The molecular mass of this protease as determined by SDS-polyacrylamide gel electrophoresis was about 18.8 kDa. Its N-terminal amino acid sequence shares no homology with any other protease. The purified enzyme substantially affected the cell wall of the phytopathogen C. perniciosa. Western-blotting analysis showed that the enzyme was present in the culture supernatant 24 h after the Trichoderma started to grow in casein-containing liquid medium. Conclusions The capacity of the Trichoderma harzianum protease to hydrolyze the cell wall of C. perniciosa indicates that this enzyme may be actually involved in the antagonistic process between the two fungi. This fact strongly suggest that hydrolytic enzyme over-producing transgenic fungi may show superior biocontrol capacity.

To assess the perspectives of patients who acquired spectacles from an eye unit/vision center in Cambodia. A sample (n = 62) of patients was selected across 4 provinces: Prey Veng, Siem Reap, Battambang, and Takeo. The Patient Spectacle Satisfaction Survey covering demographic and semistructured questions regarding patient satisfaction, style, and costs incurred was used to collect data. Information was transcribed and translated into English and analyzed by thematic coding using NVivo. Although there were more women seeking eye health care treatment, there was no significant age difference. Patient satisfaction levels were high although the patients had to pay for transportation, registration, and the glasses themselves. A total of 60 patients (96.7%) stated they would recommend the refractive service center to others. Despite a high level of awareness of eye disease such as cataract, only 2 in 10 people could accurately identify cataract as a major cause of poor vision or blindness. Most of the people (52%) blamed bad vision or blindness on dust or other foreign objects getting into the eye, old age (31%), or poor hygiene (16%). Most people will pay eye care costs once barriers to seeking treatment have been broken via education and encouragement. Satisfaction of wearing spectacles was associated with improved vision; style, color, and fit of the spectacles; and protection from sunlight and dust. The proximity of and easy access to health facilities influenced patient desire to seek treatment.

Full text: Ceratoplatanin (CP) is a secreted protein of 12.4 kDa initially identified in culture filtrates of the disease ascomycete Ceratocystis fimbriata f. sp. platani, etiological agent of the canker stain disease. CP is also the founding member of the namesake protein family, which contains fungal-secreted proteins involved in various stages of the host-fungus interaction and may act as phytotoxins or elicitors of defense response. Besides the low molecular weight, CPs have a high percentage of hydrophobic residues and share two conserved intramolecular disulfide bonds. It has been suggested that CPs have important physiological functions, including interaction with cell wall or cell membrane and manipulation of the host's defense system. Furthermore, a recent work showed that the ceratoplatanin from C. fimbriata has some degree of affinity for the saccharide 4-N-acetylglucosamine. However, its precise molecular function remains elusive. Five putative CPs have been identified in Moniliophthora perniciosa a basidiomycete fungus responsible for great economic losses in cocoa industry in the form of Witches' broom disease (WBD) , four of which had their crystal structures resolved by our group. In this work we report biophysical and functional studies on these MpCPs aiming at understanding their role and importance during the WBD progression. (author)

2012-05-01

Full Text Available Acquired methemoglobinaemia is a relatively rare condition and, therefore infrequently encountered in acute medical practice. Suspicion of the condition may be triggered when the measured PaO2 is ‘out of keeping’ with the oxygen saturations that are discovered with pulse oximetry. We describe two separate cases of acquired methemoglobinaemia secondary to the recreational use of alkyl nitrites (’poppers’. The patients presented at separate times to two different teaching hospitals in London, UK. The similarity of these cases has led the authors to conclude that a raised awareness of this potentially fatal condition, and its association with a widely-available recreational drug, is necessary to ensure a correct and timely diagnosis.

The influence of space-charge on ion cyclotron resonances and magnetron eigenfrequency in a gas-filled Penning ion trap has been investigated. Off-line measurements with K39+ using the cooling trap of the WITCH retardation spectrometer-based setup at ISOLDE/CERN were performed. Experimental ion cyclotron resonances were compared with ab initio Coulomb simulations and found to be in agreement. As an important systematic effect of the WITCH experiment, the magnetron eigenfrequency of the ion cloud was studied under increasing space-charge conditions. Finally, the helium buffer gas pressure in the Penning trap was determined by comparing experimental cooling rates with simulations.

Barlev, Michael; Mermelstein, Spencer; German, Tamsin C

2017-04-01

This study tested the hypothesis that in the minds of adult religious adherents, acquired beliefs about the extraordinary characteristics of God coexist with, rather than replace, an initial representation of God formed by co-option of the evolved person concept. In three experiments, Christian religious adherents were asked to evaluate a series of statements for which core intuitions about persons and acquired Christian beliefs about God were consistent (i.e., true according to both [e.g., "God has beliefs that are true"] or false according to both [e.g., "All beliefs God has are false"]) or inconsistent (i.e., true on intuition but false theologically [e.g., "God has beliefs that are false"] or false on intuition but true theologically [e.g., "All beliefs God has are true"]). Participants were less accurate and slower to respond to inconsistent versus consistent statements, suggesting that the core intuitions both coexisted alongside and interfered with the acquired beliefs (Experiments 1 and 2). In Experiment 2 when responding under time pressure participants were disproportionately more likely to make errors on inconsistent versus consistent statements than when responding with no time pressure, suggesting that the resolution of interference requires cognitive resources the functioning of which decreases under cognitive load. In Experiment 3 a plausible alternative interpretation of these findings was ruled out by demonstrating that the response accuracy and time differences on consistent versus inconsistent statements occur for God-a supernatural religious entity-but not for a natural religious entity (a priest).

Acquiring Synaesthesia: Insights from Training Studies

Directory of Open Access Journals (Sweden)

Nicolas eRothen

2014-03-01

Full Text Available Synaesthesia denotes a condition of remarkable individual differences in experience characterized by specific additional experiences in response to normal sensory input. Synaesthesia seems to (i run in families which suggests a genetic component, (ii is associated with marked structural and functional neural differences, and (iii is usually reported to exist from early childhood. Hence, synaesthesia is generally regarded as a congenital phenomenon. However, most synaesthetic experiences are triggered by cultural artefacts (e.g., letters, musical sounds. Evidence exists to suggest that synaesthetic experiences are triggered by the conceptual representation of their inducer stimuli. Cases were identified for which the specific synaesthetic associations are related to prior experiences and large scale studies show that grapheme-colour associations in synaesthesia are not completely random. Hence, a learning component is inherently involved in the development of specific synaesthetic associations. Researchers have hypothesized that associative learning is the critical mechanism. Recently, it has become of scientific and public interest if synaesthetic experiences may be acquired by the means of associative training procedures and whether the gains of these trainings are associated with similar cognitive benefits as genuine synaesthetic experiences. In order to shed light on these issues and inform synaesthesia researchers and the general interested public alike, we provide a comprehensive literature review on developmental aspects of synaesthesia and specific training procedures in non-synaesthetes. Under the light of a clear working definition of synaesthesia, we come to the conclusion that synaesthesia can potentially be learned by the appropriate training.

When words fail us: insights into language processing from developmental and acquired disorders.

Science.gov (United States)

Bishop, Dorothy V M; Nation, Kate; Patterson, Karalyn

2014-01-01

Acquired disorders of language represent loss of previously acquired skills, usually with relatively specific impairments. In children with developmental disorders of language, we may also see selective impairment in some skills; but in this case, the acquisition of language or literacy is affected from the outset. Because systems for processing spoken and written language change as they develop, we should beware of drawing too close a parallel between developmental and acquired disorders. Nevertheless, comparisons between the two may yield new insights. A key feature of connectionist models simulating acquired disorders is the interaction of components of language processing with each other and with other cognitive domains. This kind of model might help make sense of patterns of comorbidity in developmental disorders. Meanwhile, the study of developmental disorders emphasizes learning and change in underlying representations, allowing us to study how heterogeneity in cognitive profile may relate not just to neurobiology but also to experience. Children with persistent language difficulties pose challenges both to our efforts at intervention and to theories of learning of written and spoken language. Future attention to learning in individuals with developmental and acquired disorders could be of both theoretical and applied value.

Origins and consequences of technology acquirement by independent-living seniors: towards an integrative model.

Living independently can be challenging for seniors. Technologies are expected to help older adults age in place, yet little empirical research is available on how seniors develop a need for technologies, how they acquire these technologies, and how these subsequently affect their lives. Aging is complex, dynamic and personal. But how does this translate to seniors' adoption and acceptance of technology? To better understand origins and consequences of technology acquirement by independent-living seniors, an explorative longitudinal qualitative field study was set up. Home visits were made to 33 community-dwelling seniors living in the Netherlands, on three occasions (2012-2014). Semi-structured interviews were conducted on the timeline of acquirements, and people and factors involved in acquirements. Additionally, participants were interviewed on experiences in using technologies since acquirement. Thematic analysis was employed to analyze interview transcripts, using a realist approach to better understand the contexts, mechanisms and outcomes of technology acquirements. Findings were accumulated in a new conceptual model: The Cycle of Technology Acquirement by Independent-Living Seniors (C-TAILS), which provides an integrative perspective on why and how technologies are acquired, and why these may or may not prove to be appropriate and effective, considering an independent-living senior's needs and circumstances at a given point in time. We found that externally driven and purely desire-driven acquirements led to a higher risk of suboptimal use and low levels of need satisfaction. Technology acquirement by independent-living seniors may be best characterized as a heterogeneous process with many different origins, pathways and consequences. Furthermore, technologies that are acquired in ways that are not congruent with seniors' personal needs and circumstances run a higher risk of proving to be ineffective or inappropriate. Yet, these needs and circumstances are

Nina Calero

2014-02-01

Full Text Available The body is the main communication tool in the child, gesture and posture of those around you let you understand their environment; from birth the child begins a process of self-recognition to be strengthened in different social spheres from personal experiences, as the emission of sounds with your body, body language and play a fundamental part of your child’s condition.For the child to move in the surrounding medium is what is the most important, as this experience allows the child not only to know his or her body, but also to communicate and form his or her own identity from the personal and social relationships. It is for this reason that the recognition of his body and his skills make fundamental part of this experience is called movement. From the movement of his body the child expresses, lives and acquires skills that enable him or her to understand their environment and so develop themselves physically, cognitively and socially using basic tools of their physical structure, the gesture and posture in different emotional manifestations.

Perceptions and Experiences about Self-Disclosure of HIV Status among Adolescents with Perinatal Acquired HIV in Poor-Resourced Communities in South Africa.

Madiba, Sphiwe; Mokgatle, Mathildah

2016-01-01

Background. There is limited research on the disclosure experiences of adolescents with perinatal acquired HIV (PAH). The study explores how adolescents with PAH experience living with HIV and examined their perceptions and experiences regarding disclosure and onward self-disclosure to friends and sexual partners. Methods. Thematic analysis was used to analyze in-depth interviews conducted with 37 adolescents. Findings. Adolescents received disclosure about their status at mean age of 12 years. They perceived disclosure as necessary and appreciated the truthful communication they received. Adolescents have learned to accept and live with HIV, and they desired to be healthy and normal like other people. After receiving disclosure, they found their treatment meaningful, and they adhered to medication. However, they also expressed a strong message that their HIV status was truly their secret and that self-disclosure to others will take the feeling of being normal away from them because they will be treated differently. Conclusion. Adolescents maintained secrecy in order to be accepted by their peers but also to protect themselves from stigma and isolation. Given that adolescents want to be informed of their HIV status but desire controlling self-disclosure of their HIV status, these should form the basis for development of disclosure interventions.

This article not only reviews the essential aspects of community-acquired pneumonia for daily clinical practice, but also highlights the controversial issues and provides the newest available information. Community-acquired pneumonia is considered in a broad sense, without excluding certain variants that, in recent years, a number of authors have managed to delineate, such as healthcare-associated pneumonia. The latter form is nothing more than the same disease that affects more frail patients, with a greater number of risk factors, both sharing an overall common approach.

Squire, L R; Cohen, N J; Zouzounis, J A

1984-01-01

Recent work with amnesic patients has revealed a preserved capacity for acquiring and retaining new skills despite otherwise profound anterograde impairment. In addition to their anterograde impairment, amnesic patients also have retrograde memory loss for some information acquired prior to the amnesic event. The present experiment addresses for the first time the question of whether preservation of memory for skills is also a feature memory impairment. To determine the susceptibility of a recently learned skill to retrograde amnesia, we taught patients to read mirror-reversed words before and during the early part of a prescribed course of electroconvulsive therapy (ECT) and then tested retention of the skill after the course of treatment had been completed. Patients prescribed bilateral or right unilateral ECT and depressed patients not receiving ECT acquired the mirror-reading skill at the same rate and then retained it at the same level. For the patients prescribed ECT, intact learning and retention of the skill occurred despite retrograde amnesia for the previous testing sessions and for the words that they had read previously.

Jennings, Mary Beth; Southall, Kenneth; Gagné, Jean-Pierre

2013-01-01

There is a paucity of knowledge about social identity-management by persons with hearing loss. The objective of the study was to gain an understanding from the perspective of the participants, the ways in which workers with acquired hearing loss manage their identity in the workplace. Twelve persons with acquired hearing loss, who were gainfully employed in a variety of settings and occupations in three Canadian cities, participated in audio-recorded semi-structured interviews. A secondary qualitative analysis was conducted on transcripts of interviews collected in a previous study on factors that influence disclosure of hearing loss in the workplace. A qualitative descriptive research paradigm was adopted and content analyses were used to extract pertinent information from verbatim transcripts. Participants described a range of identity-management strategies enacted in the workplace. Five recurrent themes emerged as important considerations in the Art of Identity Management in the workplace: 1. Managing the situation, 2. Having a buddy system, 3. Feeling comfortable, 4. Using personal resources, 5. It gets easier with time. Social identity-management is a complex process. Although persons with acquired hearing loss experience different challenges from other persons with invisible stigmas, similarities in the range of social identity-management strategies employed were evident in our findings. In addition, the social cognitive learning model of disclosure appears to be relevant to the experiences of our participants.

A programme on in-pile test which involve fuel burnup up to 60 MWd/kg and up to 12 fuel rods in the experimental rig is considered. Testing methods with reference to the MIR-M1 reactor are reported. Power ramping regime can be realized either by an increase of the total reactor capacity or by displacement of the nearest to the experimental cell control rods or by combination of these two ways. A total thermal capacity of the fuel rod cluster is determined by means of the thermal balance technique. The thermal capacity of each separate fuel rod can be estimated from the distribution of their relative activity within the accuracy range 5-10%. The important condition for this procedure is to keep the initial distribution of the fuel rod heating during power ramping. Means of instrumentation are described. They are standard detectors of loop facilities and transducers installed both in the irradiation rigs and fuel rods. Different ways of processing data on the fuel rod loss of integrity are reported. When the time of fuel rod loss of tightness is placed in correspondence with its capacity, processing can be made either on the maximum fuel rod heat load or on that at crack location. The information acquired in the experiments on the burnup values, heat rating distribution, kinetics of fission product gas emission, fuel rod elongation, fuel rod diameter changes, crack availability and fission products migration is used for the development and verification of calculation codes.

Fox, Christopher J; Iaria, Giuseppe; Duchaine, Bradley C; Barton, Jason J S

2013-01-01

While a network of cortical regions contribute to face processing, the lesions in acquired prosopagnosia are highly variable, and likely result in different combinations of spared and affected regions of this network. To assess the residual functional sensitivities of spared regions in prosopagnosia, we designed a rapid event-related functional magnetic resonance imaging (fMRI) experiment that included pairs of faces with same or different identities and same or different expressions. By measuring the release from adaptation to these facial changes we determined the residual sensitivity of face-selective regions-of-interest. We tested three patients with acquired prosopagnosia, and all three of these patients demonstrated residual sensitivity for facial identity changes in surviving fusiform and occipital face areas of either the right or left hemisphere, but not in the right posterior superior temporal sulcus. The patients also showed some residual capabilities for facial discrimination with normal performance on the Benton Facial Recognition Test, but impaired performance on more complex tasks of facial discrimination. We conclude that fMRI can demonstrate residual processing of facial identity in acquired prosopagnosia, that this adaptation can occur in the same structures that show similar processing in healthy subjects, and further, that this adaptation may be related to behavioral indices of face perception.

Acquiring information about neutrino parameters by detecting supernova neutrinos

Huang, Ming-Yang; Guo, Xin-Heng; Young, Bing-Lin

2010-08-01

We consider the supernova shock effects, the Mikheyev-Smirnov-Wolfenstein effects, the collective effects, and the Earth matter effects in the detection of type II supernova neutrinos on the Earth. It is found that the event number of supernova neutrinos depends on the neutrino mass hierarchy, the neutrino mixing angle θ13, and neutrino masses. Therefore, we propose possible methods to identify the mass hierarchy and acquire information about θ13 and neutrino masses by detecting supernova neutrinos. We apply these methods to some current neutrino experiments.

Seeing the sound after visual loss: functional MRI in acquired auditory-visual synesthesia.

Yong, Zixin; Hsieh, Po-Jang; Milea, Dan

2017-02-01

Acquired auditory-visual synesthesia (AVS) is a rare neurological sign, in which specific auditory stimulation triggers visual experience. In this study, we used event-related fMRI to explore the brain regions correlated with acquired monocular sound-induced phosphenes, which occurred 2 months after unilateral visual loss due to an ischemic optic neuropathy. During the fMRI session, 1-s pure tones at various pitches were presented to the patient, who was asked to report occurrence of sound-induced phosphenes by pressing one of the two buttons (yes/no). The brain activation during phosphene-experienced trials was contrasted with non-phosphene trials and compared to results obtained in one healthy control subject who underwent the same fMRI protocol. Our results suggest, for the first time, that acquired AVS occurring after visual impairment is associated with bilateral activation of primary and secondary visual cortex, possibly due to cross-wiring between auditory and visual sensory modalities.

Yeasts acquire resistance secondary to antifungal drug treatment by adaptive mutagenesis.

Directory of Open Access Journals (Sweden)

David Quinto-Alemany

Full Text Available Acquisition of resistance secondary to treatment both by microorganisms and by tumor cells is a major public health concern. Several species of bacteria acquire resistance to various antibiotics through stress-induced responses that have an adaptive mutagenesis effect. So far, adaptive mutagenesis in yeast has only been described when the stress is nutrient deprivation. Here, we hypothesized that adaptive mutagenesis in yeast (Saccharomyces cerevisiae and Candida albicans as model organisms would also take place in response to antifungal agents (5-fluorocytosine or flucytosine, 5-FC, and caspofungin, CSP, giving rise to resistance secondary to treatment with these agents. We have developed a clinically relevant model where both yeasts acquire resistance when exposed to these agents. Stressful lifestyle associated mutation (SLAM experiments show that the adaptive mutation frequencies are 20 (S. cerevisiae -5-FC, 600 (C. albicans -5-FC or 1000 (S. cerevisiae--CSP fold higher than the spontaneous mutation frequency, the experimental data for C. albicans -5-FC being in agreement with the clinical data of acquisition of resistance secondary to treatment. The spectrum of mutations in the S. cerevisiae -5-FC model differs between spontaneous and acquired, indicating that the molecular mechanisms that generate them are different. Remarkably, in the acquired mutations, an ectopic intrachromosomal recombination with an 87% homologous gene takes place with a high frequency. In conclusion, we present here a clinically relevant adaptive mutation model that fulfils the conditions reported previously.

Acquired Inhibitors: A Special Case of Bleeding in Older Adults

Directory of Open Access Journals (Sweden)

Richard G. Stefanacci

2012-01-01

Full Text Available This literature review is intended to familiarize physicians and healthcare providers of older adults with the potential causes of acute bleeding in older adults and to review diagnostic approaches that can produce prompt identification of acute bleeding and facilitate timely treatment. Adverse events from anticoagulant treatment and nonsteroidal anti-inflammatory drug (NSAID and aspirin use and abuse are among the most common causes of bleeding in older adults. Diagnoses infrequently considered—mild congenital hemophilia, acquired hemophilia, von Willebrand disease, and platelet dysfunction—can contribute to acute bleeding in older adults. The approach to management of bleeding varies. Management of acute bleeding in older adults can be challenging because these patients often have chronic comorbidity and have been prescribed long-term concomitant medications that can complicate diagnosis and treatment. Prompt recognition of acquired hemophilia, referral to an expert hematologist, and timely initiation of treatment could improve outcome in older patients who experience bleeding episodes resulting from this condition.

Acquired Codes of Meaning in Data Visualization and Infographics: Beyond Perceptual Primitives.

Science.gov (United States)

Byrne, Lydia; Angus, Daniel; Wiles, Janet

2016-01-01

While information visualization frameworks and heuristics have traditionally been reluctant to include acquired codes of meaning, designers are making use of them in a wide variety of ways. Acquired codes leverage a user's experience to understand the meaning of a visualization. They range from figurative visualizations which rely on the reader's recognition of shapes, to conventional arrangements of graphic elements which represent particular subjects. In this study, we used content analysis to codify acquired meaning in visualization. We applied the content analysis to a set of infographics and data visualizations which are exemplars of innovative and effective design. 88% of the infographics and 71% of data visualizations in the sample contain at least one use of figurative visualization. Conventions on the arrangement of graphics are also widespread in the sample. In particular, a comparison of representations of time and other quantitative data showed that conventions can be specific to a subject. These results suggest that there is a need for information visualization research to expand its scope beyond perceptual channels, to include social and culturally constructed meaning. Our paper demonstrates a viable method for identifying figurative techniques and graphic conventions and integrating them into heuristics for visualization design.

[Validation of knowledge acquired from experience: opportunity or threat for nurses working in operating theatres?].

Chauvat-Bouëdec, Cécile

2005-06-01

The law n 2002-73, dated 17 January 2002, of social modernisation, as it is called, reformed continuing professional training in France. It established a new system of professional certification, the validation of the knowledge acquired from experience (VAE in French). Since 2003, the Health Ministry has been studying a project to set up the VAE for health professions, among which, in particular, the profession of the state registered nurse working in operating theatres (IBODES in French). A state diploma sanctions the training enabling to practise this profession. In the future, the VAE will open a new access way to this diploma. Does this evolution constitute a threat for the profession, and a risk or an opportunity for individual people? The aim of this thesis is to characterise the impacts of the VAE on the IBODE profession and its current system of training. Two sociological and educational approaches are comforted by a field survey. A historical background of the IBODE profession develops the evolution of the caring practices, and presents the evolution of the training systems. A sociological approach enables to analyse the vocational focus of the IBODE on looking at functionalist theories. Therefore, the study enables to think that the VAE will have no consequences on the vocational focus of the IBODE. The VAE is then the object of an educational approach within the context of continuing professional training. The topics on which it could apply and the resistances it causes are studied. Some examples are taken within other Ministries. This study shows that the VAE involves an adaptation of training centres. The VAE constitutes a genuine opportunity for the IBODE profession. However, to manage its setting up in a delicate human context, the field professionals should be involved as early as possible in the reflection initiated by the Ministry.

Localization of Haemophilus ducreyi in naturally acquired chancroidal ulcers.

Science.gov (United States)

Bauer, Margaret E; Townsend, Carisa A; Ronald, Allan R; Spinola, Stanley M

2006-08-01

Haemophilus ducreyi causes the sexually transmitted genital ulcer disease chancroid. In human inoculation experiments, bacteria colocalize with neutrophils and macrophages but remain extracellular. The organism also colocalizes with collagen and fibrin but not with keratinocytes, fibroblasts, laminin, or fibronectin. These relationships are established by 48 h postinoculation and persist through the pustular stage of disease. To extend these observations to the ulcerative stage of disease, and to compare results in the human model with those of natural disease, we obtained biopsies from patients with naturally acquired chancroid. All ulcers were culture positive for H. ducreyi and histologically very similar to pustules from the human model. Staining with H. ducreyi-specific monoclonal antibodies demonstrated H. ducreyi within 5 biopsies. The organism was chiefly found within the granulocytic infiltrate of the ulcer. Dual staining for H. ducreyi and eukaryotic tissue components showed that H. ducreyi colocalized with neutrophils and fibrin at the ulcerative stage of disease. No bacteria were associated with keratinocytes, fibroblasts, or collagen. Overall, these findings are consistent with results from the human model. This is the first reported study to localize bacteria specifically identified as H. ducreyi within naturally acquired chancroid.

Influence and applicability of wire-mesh sensor to acquire two phase flow dynamics

International Nuclear Information System (INIS)

Kanai, Taizo; Furuya, Masahiro; Arai, Takahiro; Shirakawa, Kenetsu

2011-01-01

Wire-mesh sensors (WMS) are able to measure void distributions and velocity profile at high speed. Immersing the wire-mesh affects the structure of two-phase flow. Experiments were performed for single rising air bubble in a vertical pipe of i.d. 50 mm and 224 mm at water velocities ranging from 0.05 to 0.52 m/s and 0.42 to 0.83 m/s. Distortion of a relatively large bubble with the wire-mesh was small in the water velocity over 0.25 m/s and confirmed by cross-correlation analysis as well. Bubble rising velocity acquired by WMS is in good agreement with that estimated high-speed camera in the experimental range. WMS has applicability to acquire two phase flow dynamics in the water velocity over 0.25 m/s. (author)

2009-01-01

Acquired aplastic anaemia is one of the important causes of pancytopenia. This study was conducted to observe the mode of presentation of acquired aplastic anaemia and to find out its possible etiological factors. Methods: It is a hospital based descriptive study of 100 patients of acquired aplastic anaemia. Results: Out of 100 patients 60 were male and 40 female. Majority (44%) of the patients were between 12 - 20 years of age. Patient presented with variable symptoms majority (40%) with fever. Most of the patients had haemoglobin levels between 4 - 6 gm/dl. (53%). Seventy percent of the cases had no obvious cause, while in 30% some known causative factors were found. Chloramphenicol was found to be the most common causative drug. Mortality was 35%. Thirty patients were partially treated and 15 were lost to follow up. Twenty patients showed improvement with treatment. Conclusions: Acquired aplastic anaemia is common among males and more prevalent in younger age group. It is idiopathic in 70% cases while 30% had some cause. It has very high mortality. Doctors need to keep in mind this fatal condition in patients presenting with anaemia and should properly investigate before prescribing antibiotics and haematinics. (author)

“Machos y brujas en la Patagonia”. Trabajo, masculinidad y espacio de la reproducción

Hernán M. Palermo

2016-05-01

Full Text Available The title "Machos and Witches in Patagonia" illustrates the core debate of this article and attempts to problematize the processes emphasized by social class and gender relations. "Machos" refers to the social construction of the oil worker as imposed by the production system. Meanwhile, "witches” refers to the witch-hunts of the sixteenth, seventeenth and eighteenth centuries, and the practice in which women were confined to the domestic sphere and their reproductive role of the workforce. Therefore, we want to analyze the link between the production process of the oil workforce inside the production system and outside of their work experiences in Comodoro Rivadavia, Argentinian Patagonia. Given that masculinity and femininity are relational gender positions, we will discuss the role of men and women in the organization of work, as a whole.

Importance of pharmacokinetic studies in the management of acquired factor X deficiency.

2016-01-01

Up to 14% of individuals with systemic AL amyloidosis develop acquired factor X deficiency, which occurs due to adsorption of factor X onto amyloid fibrils. Although baseline factor X levels are not predictive of bleeding risk in these patients, serious hemorrhagic complications can occur, particularly during invasive procedures. Optimal management strategies to attenuate bleeding risk in these patients are unknown. We describe our experience in the management of acquired factor X deficiency, secondary to systemic AL amyloidosis, in a case series of three patients who received prothrombin complex concentrates (PCCs) for treatment and prevention of bleeding events. We performed a retrospective review extracting information on baseline demographics, laboratory data, pharmacokinetic (PK) studies, and clinically documented bleeding events. Our case series demonstrates that individuals with acquired factor X deficiency secondary to amyloidosis have variable laboratory and clinical responses to PCCs. This is likely due to distinct amyloid loads and fibril sequences, leading to different binding avidities for factor X. Our data emphasize the importance of performing PK testing prior to any invasive procedures to determine the dose and frequency interval to achieve adequate factor X levels for hemostasis, given the variable response between individuals. © 2015 John Wiley & Sons A/S.

2016-05-07

Myelofibrosis and acquired hemophilia A is a rare association. To the best of our knowledge only one case of myelofibrosis and acquired hemophilia A has been previously described. A 66-year-old Caucasian man diagnosed with myelofibrosis evolving in acute myeloid leukemia was referred to us for postoperative bleeding. Hemostatic studies showed prolonged activated partial thromboplastin time, decreased factor VIII coagulation, and a high factor VIII inhibitor titer; these findings led to a diagnosis of acquired hemophilia A for which he was treated with methylprednisolone and recombinant activated factor VII on admission. Due to a lack of response he was subsequently treated with rituximab combined with activated prothrombin complex concentrates. Furthermore, he received azacytidine to treat the underlying hematological malignancies. Immunosuppressive rituximab therapy resolved acquired hemophilia A with marked efficacy. Rapid and accurate diagnosis, effective hemostatic therapy, and timely treatment for underlying disease are important in the management of acquired hemophilia A secondary to hematological malignancy.

Emergency Assessment of Debris-Flow Hazards from Basins Burned by the 2007 Witch Fire, San Diego County, Southern California

Science.gov (United States)

Cannon, Susan H.; Gartner, Joseph E.; Michael, John A.; Bauer, Mark A.; Stitt, Susan C.; Knifong, Donna L.; McNamara, Bernard J.; Roque, Yvonne M.

2007-01-01

INTRODUCTION The objective of this report is to present a preliminary emergency assessment of the potential for debris-flow generation from basins burned by the Witch Fire in San Diego County, southern California in 2007. Debris flows are among the most hazardous geologic phenomena; debris flows that followed wildfires in southern California in 2003 killed 16 people and caused tens of millions of dollars of property damage. A short period of even moderate rainfall on a burned watershed can lead to debris flows. Rainfall that is normally absorbed into hillslope soils can run off almost instantly after vegetation has been removed by wildfire. This causes much greater and more rapid runoff than is normal from creeks and drainage areas. Highly erodible soils in a burn scar allow flood waters to entrain large amounts of ash, mud, boulders, and unburned vegetation. Within the burned area and downstream, the force of rushing water, soil, and rock can destroy culverts, bridges, roadways, and buildings, potentially causing injury or death. This emergency debris-flow hazard assessment is presented as relative ranking of the predicted median volume of debris flows that can issue from basin outlets in response to 2.25 inches (57.15 mm) of rainfall over a 3-hour period. Such a storm has a 10-year return period. The calculation of debris flow volume is based on a multiple-regression statistical model that describes the median volume of material that can be expected from a recently burned basin as a function of the area burned at high and moderate severity, the basin area with slopes greater than or equal to 30 percent, and triggering storm rainfall. Cannon and others (2007) describe the methods used to generate the hazard maps. Identification of potential debris-flow hazards from burned drainage basins is necessary to issue warnings for specific basins, to make effective mitigation decisions, and to help plan evacuation timing and routes.

Mulliez, Sylvie M N; Devreese, Katrien M J

2016-04-01

Isolated acquired factor VII (FVII) deficiency is a rare haemorrhagic disorder. We report what is currently known about the pathogenesis, clinical features, diagnosis, treatment and prognosis of acquired FVII deficiency. We performed a literature search and included all articles published between 1980 and August 2015. Acquired FVII deficiency has been reported in 42 patients. There are well-established clinical diseases associated with acquired FVII deficiency, most notably infections, malignancy and haematological stem cell transplantation. The exact pathogenesis of the diseases is still unknown, but different pathophysiological hypotheses have been suggested. The clinical manifestation of acquired FVII deficiency varies greatly in severity; asymptomatic course as well as severe life-threatening bleeding diathesis and fatal bleedings have been described.

Full Text Available Martin W Besser,1 Stephen G MacDonald2 1Department of Haematology, 2Department of Specialist Haemostasis, The Pathology Partnership, Addenbrooke’s Hospital, Cambridge, UK Abstract: Acquired hypofibrinogenemia is most frequently caused by hemodilution and consumption of clotting factors. The aggressive replacement of fibrinogen has become one of the core principles of modern management of massive hemorrhage. The best method for determining the patient’s fibrinogen level remains controversial, and particularly in acquired dysfibrinogenemia, could have major therapeutic implications depending on which quantification method is chosen. This review introduces the available laboratory and point-of-care methods and discusses the relative advantages and limitations. It also discusses current strategies for the correction of hypofibrinogenemia.

Full Text Available This paper proposes an approach for the detection of changes in multitemporal Very High Resolution (VHR optical images acquired by different multispectral sensors. The proposed approach, which is inspired by a recent framework developed to support the design of change-detection systems for single-sensor VHR remote sensing images, addresses and integrates in the general approach a strategy to effectively deal with multisensor information, i.e., to perform change detection between VHR images acquired by different multispectral sensors on two dates. This is achieved by the definition of procedures for the homogenization of radiometric, spectral and geometric image properties. These procedures map images into a common feature space where the information acquired by different multispectral sensors becomes comparable across time. Although the approach is general, here we optimize it for the detection of changes in vegetation and urban areas by employing features based on linear transformations (Tasseled Caps and Orthogonal Equations, which are shown to be effective for representing the multisensor information in a homogeneous physical way irrespectively of the considered sensor. Experiments on multitemporal images acquired by different VHR satellite systems (i.e., QuickBird, WorldView-2 and GeoEye-1 confirm the effectiveness of the proposed approach.

Connectionist neuropsychology: uncovering ultimate causes of acquired dyslexia.

Science.gov (United States)

Woollams, Anna M

2014-01-01

Acquired dyslexia offers a unique window on to the nature of the cognitive and neural architecture supporting skilled reading. This paper provides an integrative overview of recent empirical and computational work on acquired dyslexia within the context of the primary systems framework as implemented in connectionist neuropsychological models. This view proposes that damage to general visual, phonological or semantic processing abilities are the root causes of different forms of acquired dyslexia. Recent case-series behavioural evidence concerning pure alexia, phonological dyslexia and surface dyslexia that supports this perspective is presented. Lesion simulations of these findings within connectionist models of reading demonstrate the viability of this approach. The commitment of such models to learnt representations allows them to capture key aspects of performance in each type of acquired dyslexia, particularly the associated non-reading deficits, the role of relearning and the influence of individual differences in the premorbid state of the reading system. Identification of these factors not only advances our understanding of acquired dyslexia and the mechanisms of normal reading but they are also relevant to the complex interactions underpinning developmental reading disorders.

Bilaterally symmetrical vitiliginous macules were present on the ear and preauricular region. This case is reported because of its rarity, absence of any detectable malignancy and development of vitiligo, which to our knowledge has not been reported earlier.

[Chronical care of schizophrenia].

Lustygier, V

2010-09-01

Schizophrenia is a complex mental disease leading to many deficits that needs a broad range of therapeutic interventions. The recent data raises the importance of the cognitive revalidation even though other interventions are also necessary in the treatment. The asylums of the former century have experienced a slow and continuous process of patient's deinstitutionalization. The global knowledge of the disorder having progressed, new multidisciplinary and multidimensional models of managing are now proposed. The psychiatric rehabilitation is one of those models having as goal the global taking charge of the disease, from the managing of the symptoms to the return to a life with good quality. The great specificity of this rehabilitation work is that it's multidisciplinary and involves a strong collaboration between the medical and the psychosocial intervening party's around a common therapeutic project. This model brings up the notion of recovery witch is, not the cure but, the experience that a patient acquires as he accepts the situation and as he recovers the feeling of being able to get going again.

Influence of violent video gaming on determinants of the acquired capability for suicide.

Teismann, Tobias; Förtsch, Eva-Maria A D; Baumgart, Patrick; Het, Serkan; Michalak, Johannes

2014-01-30

The interpersonal theory of suicidal behavior proposes that fearlessness of death and physical pain insensitivity is a necessary requisite for self-inflicted lethal self-harm. Repeated experiences with painful and provocative events are supposed to cause an incremental increase in acquired capability. The present study examined whether playing a first-person shooter-game in contrast to a first-person racing game increases pain tolerance, a dimension of the acquired capability construct, and risk-taking behavior, a risk factor for developing acquired capability. N=81 male participants were randomly assigned to either play an action-shooter or a racing game before engaging in a game on risk-taking behavior and performing a cold pressor task (CPT). Participants exhibited higher pain tolerance after playing an action shooter game than after playing a racing game. Furthermore, playing an action shooter was generally associated with heightened risk-taking behavior. Group-differences were not attributable to the effects of the different types of games on self-reported mood and arousal. Overall these results indicate that action-shooter gaming alters pain tolerance and risk-taking behavior. Therefore, it may well be that long-term consumption of violent video games increases a person's capability to enact lethal self-harm. © 2013 Published by Elsevier Ireland Ltd.

To Converse with the Devil? Speech, Sexuality, and Witchcraft in Early Modern Scotland

Directory of Open Access Journals (Sweden)

Sierra Rose Dye

2012-10-01

Full Text Available In early modern Scotland, thousands of people were accused and tried for the crime of witchcraft, many of whom were women. This paper examines the particular qualities associated with witches in Scottish belief – specifically speech and sexuality – in order to better understand how and why the witch hunts occurred. This research suggests that the growing emphasis on the words of witches during this period was a reflection of a mounting concern over the power and control of speech in early modern society. In looking at witchcraft as a speech crime, it is possible to explain not only why accused witches were more frequently women, but also how the persecution of individuals – both male and female – functioned to ensure that local and state authorities maintained a monopoly on powerful speech.

EXPERIENCES WITH ACQUIRING HIGHLY REDUNDANT SPATIAL DATA TO SUPPORT DRIVERLESS VEHICLE TECHNOLOGIES

Directory of Open Access Journals (Sweden)

Z. Koppanyi

2018-05-01

Full Text Available As vehicle technology is moving towards higher autonomy, the demand for highly accurate geospatial data is rapidly increasing, as accurate maps have a huge potential of increasing safety. In particular, high definition 3D maps, including road topography and infrastructure, as well as city models along the transportation corridors represent the necessary support for driverless vehicles. In this effort, a vehicle equipped with high-, medium- and low-resolution active and passive cameras acquired data in a typical traffic environment, represented here by the OSU campus, where GPS/GNSS data are available along with other navigation sensor data streams. The data streams can be used for two purposes. First, high-definition 3D maps can be created by integrating all the sensory data, and Data Analytics/Big Data methods can be tested for automatic object space reconstruction. Second, the data streams can support algorithmic research for driverless vehicle technologies, including object avoidance, navigation/positioning, detecting pedestrians and bicyclists, etc. Crucial cross-performance analyses on map database resolution and accuracy with respect to sensor performance metrics to achieve economic solution for accurate driverless vehicle positioning can be derived. These, in turn, could provide essential information on optimizing the choice of geospatial map databases and sensors’ quality to support driverless vehicle technologies. The paper reviews the data acquisition and primary data processing challenges and performance results.

Speech and language therapists' views about AAC system acceptance by people with acquired communication disorders.

Science.gov (United States)

Pampoulou, Eliada

2018-04-18

Some adults with acquired communication disorders are faced with an inability to communicate coherently through verbal speech with their communication partners. Despite the fact that a variety of augmentative and alternative communication (AAC) aided systems is available to assist them in communicating, not all adults accept them. In Cyprus, there is scant research focusing on the factors that are linked to AAC system acceptance and abandonment. To address this gap, this research involves exploring the experiences of six speech and language therapists supporting adults with acquired communication disorders, who could benefit from the use of AAC systems. The main research question is: What are the factors that influence AAC system acceptance or abandonment? The method used for data collection, was semi-structured interviews and the transcripts were analyzed thematically. The findings show that a number of factors influence the acceptance of AAC systems. These include the time since onset and acceptance of disability, the person's attitude towards communication facilitators, and the perceptions about AAC systems. These findings indicate that the process of accepting an AAC system is multi-layered and these layers are interrelated. More research is warranted focusing directly on the experiences of people with acquired communication disorders and their communication partners. Implications for Rehabilitation The different myths about AAC systems need to be challenged such that awareness about their usefulness is raised. AAC specialists need to find ways to spread the message that AAC systems can actually support language, speech and communication through different dissemination avenues, such as articles in newspapers and talks through the media.

Recovering With Acquired Apraxia of Speech: The First 2 Years.

Science.gov (United States)

Haley, Katarina L; Shafer, Jennifer N; Harmon, Tyson G; Jacks, Adam

2016-12-01

This study was intended to document speech recovery for 1 person with acquired apraxia of speech quantitatively and on the basis of her lived experience. The second author sustained a traumatic brain injury that resulted in acquired apraxia of speech. Over a 2-year period, she documented her recovery through 22 video-recorded monologues. We analyzed these monologues using a combination of auditory perceptual, acoustic, and qualitative methods. Recovery was evident for all quantitative variables examined. For speech sound production, the recovery was most prominent during the first 3 months, but slower improvement was evident for many months. Measures of speaking rate, fluency, and prosody changed more gradually throughout the entire period. A qualitative analysis of topics addressed in the monologues was consistent with the quantitative speech recovery and indicated a subjective dynamic relationship between accuracy and rate, an observation that several factors made speech sound production variable, and a persisting need for cognitive effort while speaking. Speech features improved over an extended time, but the recovery trajectories differed, indicating dynamic reorganization of the underlying speech production system. The relationship among speech dimensions should be examined in other cases and in population samples. The combination of quantitative and qualitative analysis methods offers advantages for understanding clinically relevant aspects of recovery.

Bone, C; O'Reilly, M; Karim, K; Vostanis, P

2015-05-01

Recent initiatives have emphasized the ongoing need to include children in healthcare research, which is relevant to the development of both paediatric and mental healthcare services. Our aim was to contribute children and their parents' perceptions and experiences of Child and Adolescent Mental Health Services (CAMHS), with the objective of providing guidance for those wishing to improve inclusivity and empowerment. We performed a thematic analysis of interview data taken from 11 children (9 boys, 2 girls, aged 8-12) and their parents (12 mothers, 2 fathers), who had recently been referred to CAMHS for mental health and educational problems. Three core themes emerged from the data. Fear of the unknown refers to emotional apprehension due to uncertainty of what happens in CAMHS. However children also provided useful reassurances for future service users. Therapeutic engagement refers to the importance of being listened to and building up good relationships with professionals. Finally making services acceptable was discussed in terms of issues of accessibility, session tolerances and suggestions for the development of child-centred services. Children were able to provide potentially useful opinions of CAMHS. In a time of limited resources it is imperative that the voices of children and their parents are acknowledged in order to improve accessibility and experiences within CAMHS. © 2014 John Wiley & Sons Ltd.

2011-01-01

Full Text Available Abstract Introduction Little is known about splenic rupture in patients who develop systemic acquired A amyloidosis. This is the first report of a case of atraumatic splenic rupture in a patient with acquired A amyloidosis from chronic injection drug use. Case presentation A 58-year-old Caucasian man with a long history of injection drug use, hospitalized for infective endocarditis, experienced atraumatic splenic rupture and underwent splenectomy. Histopathological and microbiological analyses of the splenic tissue were consistent with systemic acquired A amyloidosis, most likely from injection drug use, that led to splenic rupture without any recognized trauma or evidence of bacterial embolization to the spleen. Conclusion In patients with chronic inflammatory conditions, including the use of injection drugs, who experience acute onset of left upper quadrant pain, the diagnosis of atraumatic splenic rupture must be considered.

Witches' broom disease (WBD) caused by the fungus Moniliophthora perniciosa is responsible for considerable economic losses for cacao producers. One of the ways to combat WBD is to plant resistant cultivars. Resistance may be governed by a few genetic factors, mainly found in wild germplasm. We developed a dense genetic linkage map with a length of 852.8 cM that contains 3,526 SNPs and is based on the MP01 mapping population, which counts 459 trees from a cross between the resistant 'TSH 1188' and the tolerant 'CCN 51' at the Mars Center for Cocoa Science in Barro Preto, Bahia, Brazil. Seven quantitative trait loci (QTL) that are associated with WBD were identified on five different chromosomes using a multi-trait QTL analysis for outbreeders. Phasing of the haplotypes at the major QTL region on chromosome IX on a diversity panel of genotypes clearly indicates that the major resistance locus comes from a well-known source of WBD resistance, the clone 'SCAVINA 6'. Various potential candidate genes identified within all QTL may be involved in different steps leading to disease resistance. Preliminary expression data indicate that at least three of these candidate genes may play a role during the first 12 h after infection, with clear differences between 'CCN 51' and 'TSH 1188'. We combined the information from a large mapping population with very distinct parents that segregate for WBD, a dense set of mapped markers, rigorous phenotyping capabilities and the availability of a sequenced genome to identify several genomic regions that are involved in WBD resistance. We also identified a novel source of resistance that most likely comes from the 'CCN 51' parent. Thanks to the large population size of the MP01 population, we were able to pick up QTL and markers with relatively small effects that can contribute to the creation and selection of more tolerant/resistant plant material.

Isolated acquired factor VII deficiency is a rare coagulopathy. It has been reported in 31 patients with malignancy, sepsis, postoperatively, aplastic anemia, and during bone marrow transplantation. We discuss, through a new case of acquired factor VII deficiency, the characteristics of this disease when it is associated with acute myeloid leukemia. Acquired factor VII deficiency in hematological diseases can be caused by intensive chemotherapy, infections, or hepatic dysfunction. The best treatment in developing countries remains corticosteroids associated with plasma exchange, frozen plasma, and antibiotics.

Limitations in methods for the rapid diagnosis of hospital-acquired infections often delay initiation of effective antimicrobial therapy. New diagnostic approaches offer potential clinical and cost-related improvements in the management of these infections. We developed a decision modeling framework to assess the potential cost-effectiveness of a rapid biomarker assay to identify hospital-acquired infection in high-risk patients earlier than standard diagnostic testing. The framework includes parameters representing rates of infection, rates of delayed appropriate therapy, and impact of delayed therapy on mortality, along with assumptions about diagnostic test characteristics and their impact on delayed therapy and length of stay. Parameter estimates were based on contemporary, published studies and supplemented with data from a four-site, observational, clinical study. Extensive sensitivity analyses were performed. The base-case analysis assumed 17.6% of ventilated patients and 11.2% of nonventilated patients develop hospital-acquired infection and that 28.7% of patients with hospital-acquired infection experience delays in appropriate antibiotic therapy with standard care. We assumed this percentage decreased by 50% (to 14.4%) among patients with true-positive results and increased by 50% (to 43.1%) among patients with false-negative results using a hypothetical biomarker assay. Cost of testing was set at $110/d. In the base-case analysis, among ventilated patients, daily diagnostic testing starting on admission reduced inpatient mortality from 12.3 to 11.9% and increased mean costs by $1,640 per patient, resulting in an incremental cost-effectiveness ratio of $21,389 per life-year saved. Among nonventilated patients, inpatient mortality decreased from 7.3 to 7.1% and costs increased by $1,381 with diagnostic testing. The resulting incremental cost-effectiveness ratio was $42,325 per life-year saved. Threshold analyses revealed the probabilities of developing

Extracorporeal membrane oxygenation is a rescue therapy used to support severe cardiorespiratory failure. Data on outcomes from severe community-acquired pneumonia in adults receiving rescue extracorporeal membrane oxygenation are mainly confined to single-center experiences or specific pathogens. We examined data from the Extracorporeal Life Support Organisation registry to identify risk factors for poor outcomes in adult patients with community-acquired pneumonia. Retrospective data analysis. Extracorporeal Life Support Organization Registry database. We collected deidentified data on adult patients (> 18 yr) receiving extracorporeal membrane oxygenation for community-acquired pneumonia between 2002 and 2012. Patients with incomplete data or brain death were excluded. The primary outcome measure was in-hospital mortality. Other measurements included demographic information, pre-extracorporeal membrane oxygenation mechanical ventilation and biochemical variables, inotrope requirements, extracorporeal membrane oxygenation mode, duration, and complications. Initial univariate analysis assessed potential associations between survival and various pre-extracorporeal membrane oxygenation and extracorporeal membrane oxygenation factors. Variables with p values of less than 0.1 were considered for logistic regression analysis to identify predictors of mortality. None. One thousand fifty-five patients, who satisfied inclusion criteria, were included in the final analysis. There was an increase in the number of patients cannulated per annum over the 10-year period studied. Univariate analysis identified pre-extracorporeal membrane oxygenation and extracorporeal membrane oxygenation variables associated with high mortality. Further multiple regression analysis identified certain pre-extracorporeal membrane oxygenation factors as predictors of mortality, including duration of mechanical ventilation prior to extracorporeal membrane oxygenation, lower arterial pressure, fungal

In response to changing internal and external situations, we always need to adapt our behavior based on previous experiences, particularly, acquired stimulus-outcome information. The orbitofrontal cortex (OFC), a prefrontal cortical region, is critical for this type of decision-making. The current understanding of the fundamental functions of the OFC has been reviewed by introducing, as an example, how the OFC contributes to the processing of uncertain rewards. Furthermore, the importance of revealing context and temporally specific causal roles of neural circuits including the OFC in decision-making, as well as the techniques to achieve the goal, have been discussed.

MRI of fetal acquired brain lesions

2006-01-01

Acquired fetal brain damage is suspected in cases of destruction of previously normally formed tissue, the primary cause of which is hypoxia. Fetal brain damage may occur as a consequence of acute or chronic maternal diseases, with acute diseases causing impairment of oxygen delivery to the fetal brain, and chronic diseases interfering with normal, placental development. Infections, metabolic diseases, feto-fetal transfusion syndrome, toxic agents, mechanical traumatic events, iatrogenic accidents, and space-occupying lesions may also qualify as pathologic conditions that initiate intrauterine brain damage. MR manifestations of acute fetal brain injury (such as hemorrhage or acute ischemic lesions) can easily be recognized, as they are hardly different from postnatal lesions. The availability of diffusion-weighted sequences enhances the sensitivity in recognizing acute ischemic lesions. Recent hemorrhages are usually readily depicted on T2 (*) sequences, where they display hypointense signals. Chronic fetal brain injury may be characterized by nonspecific changes that must be attributable to the presence of an acquired cerebral pathology. The workup in suspected acquired fetal brain injury also includes the assessment of extra-CNS organs that may be affected by an underlying pathology. Finally, the placenta, as the organ that mediates oxygen delivery from the maternal circulation to the fetus, must be examined on MR images

Infections, metabolic diseases, feto-fetal transfusion syndrome, toxic agents, mechanical traumatic events, iatrogenic accidents, and space-occupying lesions may also qualify as pathologic conditions that initiate intrauterine brain damage. MR manifestations of acute fetal brain injury (such as hemorrhage or acute ischemic lesions) can easily be recognized, as they are hardly different from postnatal lesions. The availability of diffusion-weighted sequences enhances the sensitivity in recognizing acute ischemic lesions. Recent hemorrhages are usually readily depicted on T2 (*) sequences, where they display hypointense signals. Chronic fetal brain injury may be characterized by nonspecific changes that must be attributable to the presence of an acquired cerebral pathology. The workup in suspected acquired fetal brain injury also includes the assessment of extra-CNS organs that may be affected by an underlying pathology. Finally, the placenta, as the organ that mediates oxygen delivery from the maternal circulation to the fetus, must be examined on MR images.

Languages exhibit sociolinguistic variation, such that adult native speakers condition the usage of linguistic variants on social context, gender, and ethnicity, among other cues. While the existence of this kind of socially conditioned variation is well-established, less is known about how it is acquired. Studies of naturalistic language use by children provide various examples where children's production of sociolinguistic variants appears to be conditioned on similar factors to adults' production, but it is difficult to determine whether this reflects knowledge of sociolinguistic conditioning or systematic differences in the input to children from different social groups. Furthermore, artificial language learning experiments have shown that children have a tendency to eliminate variation, a process which could potentially work against their acquisition of sociolinguistic variation. The current study used a semi-artificial language learning paradigm to investigate learning of the sociolinguistic cue of speaker identity in 6-year-olds and adults. Participants were trained and tested on an artificial language where nouns were obligatorily followed by one of two meaningless particles and were produced by one of two speakers (one male, one female). Particle usage was conditioned deterministically on speaker identity (Experiment 1), probabilistically (Experiment 2), or not at all (Experiment 3). Participants were given tests of production and comprehension. In Experiments 1 and 2, both children and adults successfully acquired the speaker identity cue, although the effect was stronger for adults and in Experiment 1. In addition, in all three experiments, there was evidence of regularization in participants' productions, although the type of regularization differed with age: children showed regularization by boosting the frequency of one particle at the expense of the other, while adults regularized by conditioning particle usage on lexical items.

Unlike congenital port wine stain (PWS), an acquired PWS is a rare vascular lesion that develops later in life. Although solar damage is associated with acquired PWS, there is no reported case of acquired PWS after sunburn in the literature. We report a case of a 54-year-old man diagnosed with acquired PWS possibly caused by repeated sunburn. We recommended laser treatment to our patient; however, the patient did not chose to receive any treatment. Our case demonstrates a possible rare occurrence of an acquired PWS after sunburn with larger lesions and more diffuse distribution. For this reason, our case differs from other acquired PWS cases. © 2016 The International Society of Dermatology.

In February 2007, sweet orange trees with characteristic symptoms of huanglongbing (HLB) were encountered in a region of São Paulo state (SPs) hitherto free of HLB. These trees tested negative for the three liberibacter species associated with HLB. A polymerase chain reaction (PCR) product from symptomatic fruit columella DNA amplifications with universal primers fD1/rP1 was cloned and sequenced. The corresponding agent was found to have highest 16S rDNA sequence identity (99%) with the pigeon pea witches'-broom phytoplasma of group 16Sr IX. Sequences of PCR products obtained with phytoplasma 16S rDNA primer pairs fU5/rU3, fU5/P7 confirm these results. With two primers D7f2/D7r2 designed based on the 16S rDNA sequence of the cloned DNA fragment, positive amplifications were obtained from more than one hundred samples including symptomatic fruits and blotchy mottle leaves. Samples positive for phytoplasmas were negative for liberibacters, except for four samples, which were positive for both the phytoplasma and 'Candidatus Liberibacter asiaticus'. The phytoplasma was detected by electron microscopy in the sieve tubes of midribs from symptomatic leaves. These results show that a phytoplasma of group IX is associated with citrus HLB symptoms in northern, central, and southern SPs. This phytoplasma has very probably been transmitted to citrus from an external source of inoculum, but the putative insect vector is not yet known.

Family members' needs and experiences of driving disruption over time following an acquired brain injury: an evolving issue.

Science.gov (United States)

Liang, Phyllis; Gustafsson, Louise; Liddle, Jacki; Fleming, Jennifer

2017-07-01

Family members often assume the role of driver for individuals who are not driving post-acquired brain injury (ABI). Given that return to driving can be unpredictable and uncertain, the impact of driving disruption on family members may vary at different stages post-injury. This study aims to understand the needs and experiences of family members over time during driving disruption following an ABI. A qualitative prospective longitudinal research design was used with semi-structured interviews at recruitment to study, 3 and 6 months later. Fourteen family members completed 41 interviews. The longitudinal data revealed four phases of driving disruption: (1) Wait and see, (2) Holding onto a quick fix, (3) No way out, and (4) Resolution and adjustment. The phases described a process of building tension and a need for support and resolution over time. Holding onto a quick fix is a pivotal phase whereby supports, such as engagement in realistic goal setting, are essential to facilitate family members' resolution of driving disruption issues. Family members who see no way out might not actively seek help and these points to a need for long-term and regular follow-ups. Future research can explore ways to support family members at these key times. Implications for rehabilitation Health professionals need to facilitate the process of fostering hope in family members to set realistic expectations of return to driving and the duration of driving disruption. It is necessary to follow-up with family members even years after ABI as the issue of driving disruption could escalate to be a crisis and family members might not actively seek help. Health professionals can consider both practical support for facilitating transport and emotional support when addressing the issue of driving disruption with family members.

Stobiecki, Marcin; Czarnobilska, Ewa; Obtułowicz, Krystyna

Acquired angioedema is a rare disease caused by a deficiency of C1 esterase inhibitor with recurrent swelling symptoms. It may occur in the course of lymphoproliferative disorders or autoimmune diseases. Symptoms resemble hereditary angioedema, and the only differentiating features is negative family history, late onset of symptoms and accompanying lymphoproliferative disorder. The aim of the study was to analyze the cases of acquired angioedema. The retrospective analysis of 341 patients from the registry of patients with C1 inhibitor deficiency. Results: We identified 4 patients among 119 with HAE (3.57%) diagnosed in this same period of time 2012-2016 who fulfilled the criteria of acquired edema. In two cases the primary reason of angioedema was lymphoproliferive disease, in two monoclonal gammapathy of unknown reason. We analyzed also the results of laboratory tests C4, C1 inhibitor, C1q. In all cases the face was dominated localization. After the treatment of primary lymphoproliferive disease, in two cases, we observed total remission of angioedema. Only one patient with gammapathy require treatment with C1 inhibitor during the attacks. In these case we observed both plasma deriver, and recombinant C1 inhibitor were effective.

Significance of anaerobes and oral bacteria in community-acquired pneumonia.

Directory of Open Access Journals (Sweden)

Kei Yamasaki

Full Text Available BACKGROUND: Molecular biological modalities with better detection rates have been applied to identify the bacteria causing infectious diseases. Approximately 10-48% of bacterial pathogens causing community-acquired pneumonia are not identified using conventional cultivation methods. This study evaluated the bacteriological causes of community-acquired pneumonia using a cultivation-independent clone library analysis of the 16S ribosomal RNA gene of bronchoalveolar lavage specimens, and compared the results with those of conventional cultivation methods. METHODS: Patients with community-acquired pneumonia were enrolled based on their clinical and radiological findings. Bronchoalveolar lavage specimens were collected from pulmonary pathological lesions using bronchoscopy and evaluated by both a culture-independent molecular method and conventional cultivation methods. For the culture-independent molecular method, approximately 600 base pairs of 16S ribosomal RNA genes were amplified using polymerase chain reaction with universal primers, followed by the construction of clone libraries. The nucleotide sequences of 96 clones randomly chosen for each specimen were determined, and bacterial homology was searched. Conventional cultivation methods, including anaerobic cultures, were also performed using the same specimens. RESULTS: In addition to known common pathogens of community-acquired pneumonia [Streptococcus pneumoniae (18.8%, Haemophilus influenzae (18.8%, Mycoplasma pneumoniae (17.2%], molecular analysis of specimens from 64 patients with community-acquired pneumonia showed relatively higher rates of anaerobes (15.6% and oral bacteria (15.6% than previous reports. CONCLUSION: Our findings suggest that anaerobes and oral bacteria are more frequently detected in patients with community-acquired pneumonia than previously believed. It is possible that these bacteria may play more important roles in community-acquired pneumonia.

Association between Mycobacterium tuberculosis complex phylogenetic lineage and acquired drug resistance.

Directory of Open Access Journals (Sweden)

Courtney M Yuen

Full Text Available BACKGROUND: Development of resistance to antituberculosis drugs during treatment (i.e., acquired resistance can lead to emergence of resistant strains and consequent poor clinical outcomes. However, it is unknown whether Mycobacterium tuberculosis complex species and lineage affects the likelihood of acquired resistance. METHODS: We analyzed data from the U.S. National Tuberculosis Surveillance System and National Tuberculosis Genotyping Service for tuberculosis cases during 2004-2011 with assigned species and lineage and both initial and final drug susceptibility test results. We determined univariate associations between species and lineage of Mycobacterium tuberculosis complex bacteria and acquired resistance to isoniazid, rifamycins, fluoroquinolones, and second-line injectables. We used Poisson regression with backward elimination to generate multivariable models for acquired resistance to isoniazid and rifamycins. RESULTS: M. bovis was independently associated with acquired resistance to isoniazid (adjusted prevalence ratio = 8.46, 95% CI 2.96-24.14 adjusting for HIV status, and with acquired resistance to rifamycins (adjusted prevalence ratio = 4.53, 95% CI 1.29-15.90 adjusting for homelessness, HIV status, initial resistance to isoniazid, site of disease, and administration of therapy. East Asian lineage was associated with acquired resistance to fluoroquinolones (prevalence ratio = 6.10, 95% CI 1.56-23.83. CONCLUSIONS: We found an association between mycobacterial species and lineage and acquired drug resistance using U.S. surveillance data. Prospective clinical studies are needed to determine the clinical significance of these findings, including whether rapid genotyping of isolates at the outset of treatment may benefit patient management.

We previously reported a simple prognostic indicator in community-acquired pneumonia (CAP: blood urea nitrogen to serum albumin (B/A ratio. This retrospective study investigated the prognostic value of severity indicators in NHAP versus CAP in elderly patients. Methods: Patients aged ≥65 years and hospitalized because of NHAP or CAP within the previous 3 years were enrolled. Demographics, coexisting illnesses, laboratory and microbiological findings, and severity scores (confusion, urea, respiratory rate, blood pressure, and age ≥65 [CURB-65] scale; age, dehydration, respiratory failure, orientation disturbance, and pressure [A-DROP] scale; and pneumonia severity index [PSI] were retrieved from medical records. The primary outcome was mortality within 28 days of admission. Results: In total, 138 NHAP and 307 CAP patients were enrolled. Mortality was higher in NHAP (18.1% than in CAP (4.6% (P<0.001. Patients with NHAP were older and had lower functional status and a higher rate of do-not-resuscitate orders, heart failure, and cerebrovascular diseases. The NHAP patients more frequently had typical bacterial pathogens. Using the receiver-operating characteristics curve for predicting mortality, the area under the curve in NHAP was 0.70 for the A-DROP scale, 0.69 for the CURB-65 scale, 0.67 for the PSI class, and 0.65 for the B/A ratio. The area under the curve in CAP was 0.73 for the A-DROP scale, 0.76 for the CURB-65 scale, 0.81 for the PSI class, and 0.83 for the B/A ratio. Conclusion: Patient mortality was greater in NHAP than in CAP. Patient characteristics, coexisting illnesses, and detected pathogens differed greatly between NHAP and CAP.

Influence of sensation seeking on response to alcohol versus placebo: implications for the acquired preparedness model.

Science.gov (United States)

Scott, Caitlin; Corbin, William R

2014-01-01

Previous research has identified several aspects of behavioral undercontrol that are associated with heavy drinking and problems. Further, research on the acquired preparedness model (Smith and Anderson, 2001) has identified biased learning as a potential mechanism of these effects. Traits like sensation seeking have been linked to stronger positive and weaker negative expectancies, which, in turn, contribute to increased risk for heavy drinking and problems. Although expectancies are thought to represent potentially biased expectations about drinking outcomes, they may also reflect individual differences in alcohol response. The present study examined the strength of associations between sensation seeking and both expectancies (response to placebo) and subjective response under alcohol. Using a between-subjects design, young adult social drinkers (N = 236) were randomly assigned to receive alcohol (target breath alcohol concentration of .08%) or placebo, after which they reported on subjective experiences of stimulation and sedation. Sensation seeking was significantly related to stimulant response, and the strength of this association did not differ by beverage condition (alcohol vs. placebo). The findings argue against a pharmacological explanation for results of prior studies of the acquired preparedness model and support a biased learning interpretation of relations between sensation seeking and positive expectancies. Results also extend the findings on the acquired preparedness model to an implicit measure of positive alcohol expectancies (subjective response to placebo). Future studies using additional measures of implicit expectancies (e.g., Implicit Association Test) would be helpful in determining the relative strength of implicit and explicit expectancies as mediators within the acquired preparedness model.

Innate-Type and Acquired-Type Allergy Regulated by IL-33

2014-01-01

Full Text Available We propose two types of allergic response: IgE-dependent and IgE-independent, and designate these as 'acquired-type allergy' and 'innate-type allergy', respectively. IL-33 stimulates both innate (basophils, mast cells, or group 2 innate lymphoid cells and acquired (Th2 cells allergy-related cells to induce and/or augment Th2 cytokine production, which leads to eosinophilic inflammation in vivo. Thus, IL-33 is an essential regulator for both 'innate-type allergy' and 'acquired-type allergy', and might be an attractive therapeutic target for allergic diseases.

Toward relating the subthalamic nucleus spiking activity to the local field potentials acquired intranuclearly

International Nuclear Information System (INIS)

Michmizos, K P; Nikita, K S; Sakas, D

2011-01-01

Studies on neurophysiological correlates of the functional magnetic resonance imaging (fMRI) signals reveal a strong relationship between the local field potential (LFP) acquired invasively and metabolic signal changes in fMRI experiments. Most of these studies failed to reveal an analogous relationship between metabolic signals and the spiking activity. That would allow for the prediction of the neural activity exclusively from the fMRI signals. However, the relationship between fMRI signals and spiking activity can be inferred indirectly provided that the LFPs can be used to predict the spiking activity of the area. Until now, only the LFP–spike relationship in cortical areas has been examined. Herein, we show that the spiking activity can be predicted by the LFPs acquired in a deep nucleus, namely the subthalamic nucleus (STN), using a nonlinear cascade model. The model can reproduce the spike patterns inside the motor area of the STN that represent information about the motor plans. Our findings expand the possibility of further recruiting non-invasive neuroimaging techniques to understand the activity of the STN and predict or even control movement

Four women (80 %) presented with heavy or intermittent vaginal bleeding after obstetric manipulation. One woman (20 %) was treated for an incidental AVM discovered on ultrasound after an uncomplicated cesarean section. Three women underwent one embolization procedure and two women required two procedures. Embolization material included NBCA in six procedures (80 %) and gelatin sponge in one procedure (20 %).ResultsEmbolization resulted in angiographic stasis of flow in all seven procedures. Four women (80 %) presented with vaginal bleeding which was improved after treatment. One woman returned 24 days after unilateral embolization with recurrent bleeding, which resolved after retreatment. One woman underwent two treatments for an asymptomatic lesion identified on ultrasound. There were no major complications. Three women (60 %) experienced mild postembolization pelvic pain that was controlled with non-steroidal anti-inflammatory drugs. Three women (60 %) had pregnancies and deliveries after embolization.ConclusionsTAE is a safe alternative to surgical therapy for acquired uterine AVMs with the potential to maintain fertility. Experience from this case series suggests that NBCA provides predictable and effective occlusion.

We find that acquired credit unions during the period 2008 (third quarter to 2014 (first quarter experienced negative return on assets for several quarters prior to their takeover. This was the result of a declining loan portfolio and increasing charge offs. In spite of decreasing lending activity, such credit unions continued to increase their deposits, i.e., adding to their cost base. Due to declining loans, their net interest margin as a proportion of deposits was also in decline. We argue that this is an indicator of poor management ability. Furthermore, our analysis finds that operating expenses were increasing over time, something that has been documented in previous literature also for smaller credit unions and is attributable to lack of economies of scale. The average asset size of the acquired credit unions in our sample is about $22 million just before acquisition. We attribute our findings to poor business strategy followed by such credit unions. We also conclude that signs of trouble are evident up to two years before merger on average and regulatory policy may have to become more proactive to manage the consolidation challenge faced by the credit union industry in general.

We report the history of a 38-year-old male native of Sri Lanka admitted to the emergency ward because of chest pain and shortness of breath. On physical and radiographic examination a bilateral predominantly right-sided pneumonia was found. The patient was admitted to the medical ICU and an antibiotic regimen with amoxicillin/clavulanic acid and erythromycin was initiated. Shortly afterwards septic shock developed. The patient was intubated and received high doses of catecholamines. He died 30 hours after admission to the hospital. Cultures from sputum, tracheal aspirate and blood grew Acinetobacter baumanni. Acinetobacter is an ubiquitous gram-negative rod with coccobacillary appearance in clinical specimens, that may appear gram-positive due to poor discoloration on Gram-stain. It is a well known causative agent of nosocomial infections, particularly in intensive care units. Community-acquired pneumonias, however, are quite rare. Sporadic cases have been reported from the US, Papua-New Guinea and Australia. Interestingly, these pneumonias are fulminant and have a high mortality. Chronic obstructive lung disease, diabetes, and tobacco and alcohol consumption appear to be predisposing factors. Due to the rapid course and poor prognosis, prompt diagnosis and adequate antibiotic treatment are indicated. Antibiotics use for community-acquired pneumonias, such as amoxicillin/clavulanic acid or macrolides, are not sufficient. Appropriate antibiotics for the initial treatment of suspected Acinetobacter infections include imipenem and carboxy- and ureidopenicillins combined with an aminoglycoside.

The evolution of witchcraft and the meaning of healing in colonial Andean society.

Science.gov (United States)

Silverblatt, I

1983-12-01

This paper explores the ways in which traditional beliefs of Andean peoples regarding health and sickness were transformed by the process of Spanish colonization. It also examines how the colonial context devolved new meanings and powers on native curers. The analysis of these transformations in Andean systems of meanings and role structures relating to healing depends on an examination of the European witchcraze of the 16th-17th centuries. The Spanish conquest of the Inca empire in the mid-1500's coincided with the European witch hunts; it is argued that the latter formed the cultural lens through which the Spanish evaluated native religion--the matrix through which Andean concepts of disease and health were expressed--as well as native curers. Andean religion was condemned as heresy and curers were condemned as witches. Traditional Andean cosmology was antithetical to 16th century European beliefs in the struggle between god and the devil, between loyal Christians and the Satan's followers. Consequently, European concepts of disease and health based on the power of witches, Satan's adherents, to cause harm and cure were alien to pre-Columbian Andean thought. Ironically European concepts of Satan and the supposed powers of witches began to graft themselves onto the world view of Andean peoples. The ensuing dialectic of ideas as well as the creation of new healers/witches forged during the imposition of colonial rule form the crux of this analysis.

Beyond Democratic Tolerance: Witch Killings in Timor-Leste

2015-01-01

Full Text Available Newly democratising states experience challenges in reconciling “traditional” or “customary” dispute resolution practices with newly established state-based legal systems based on the rule of law. For Timor-Leste, these tensions are pronounced in continuing debates concerning the killing or injuring of women accused of witchcraft. Defences of extrajudicial punishments tend to conflate democracy with local support and fail to deal with the key institutions of democratic systems, including the rule of law, political equality, and civil rights. In Timor-Leste’s case, where equality and social rights were incorporated into the Constitution as fundamental governmental obligations, localised extrajudicial punishments threaten internal and external state legitimacy and highlight the difficulties of ensuring the primacy of state-based institutions. Extrajudicial punishments challenge Timor-Leste’s capacity to consolidate new liberal democratic political institutions.

The initial antibiotic therapy of community-acquired pneumonia is carried out empirically. In the treatment of severe community-acquired pneumonia in children from 2 months to 5 years, the drug of choice is amoxicillin orally. Macrolides are the drugs of choice for children aged 5 to 16 years. In severe pneumonia, drugs of choice are amoxicillin clavulanate, 2nd–4th generation cephalosporins. In general, the duration of antibiotic therapy in the community-acquired pneumonia caused by typical bacteria is 7–10 days, by atypical bacteria — 10–14 days. In the real clinical practice, the errors associated with the choice of drug, route of administration, dosage, regimen of application, length of treatment are frequent during antibacterial therapy.

Full Text Available Objective. We present the case of a 73-year-old female, with no family or personal history of a bleeding disorder, who had a classic presentation for acquired hemophilia A. Factor VIII activity was low but detectable and a factor VIII inhibitor was undetectable. Methods. The patient’s plasma was comprehensively studied to determine the cause of the acquired coagulopathy. Using the Nijmegen modification of the Bethesda assay, no factor VIII autoantibody was measureable despite varying the incubation time from 1 to 3 hours. Results. The aPTT was prolonged at 46.8 seconds, which did not correct in the 4 : 1 mix but did with 1 : 1 mix. Using a one stage factor VIII activity assay, the FVIII activity was 16% and chromogenic FVIII activity was also 16%. The patient was treated with recombinant FVII and transfusion, significantly reducing bleeding. Long-term therapy was initiated with cyclophosphamide and prednisone with normalization of FVIII activity. Conclusions. Physicians can be presented with the challenging clinical picture of an acquired factor VIII inhibitor without a detectable inhibitor by the Bethesda assay. Standard therapy for an acquired hemophilia A should be considered.

Hand hygiene is important to prevent hospital-acquired infections. Patients' hand hygiene is just as important as hospital workers' hand hygiene. Hospital-acquired infection rates remain a concern across health centers. To improve patients' hand hygiene through the promotion and use of hand washing with soap and water, hand sanitizer, or both and improve patients' education to reduce hospital-acquired infections. In August 2013, patients in a cardiothoracic postsurgical step-down unit were provided with individual bottles of hand sanitizer. Nurses and nursing technicians provided hand hygiene education to each patient. Patients completed a 6-question survey before the intervention, at hospital discharge and 1, 2, and 3 months after the intervention. Hospital-acquired infection data were tracked monthly by infection prevention staff. Significant correlations were found between hand hygiene and rates of infection with vancomycin-resistant enterococci ( P = .003) and methicillin-resistant Staphylococcus aureus ( P = .01) after the intervention. After the implementation of hand hygiene interventions, rates of both infections declined significantly and patients reported more staff offering opportunities for and encouraging hand hygiene. This quality improvement project demonstrates that increased hand hygiene compliance by patients can influence infection rates in an adult cardiothoracic step-down unit. The decreased infection rates and increased compliance with hand hygiene among the patients may be attributed to the implementation of patient education and the increased accessibility and use of hand sanitizer. ©2017 American Association of Critical-Care Nurses.

Cefixime is an oral third generation cephalosporin, frequently used in respiratory tract infections (RTI) in the pediatric population. However, in some publications cefixime has demonstrated poor efficacy against staphylococci and streptococci. of this study was to evaluate the efficacy of cefixime in the treatment of community-acquired infections in a country where parenteral third generation cephalosporins have been used for a long time. The present study was designed to assess the clinical efficacy, bacteriological eradication rates and tolerability of cefixime in children with community-acquired upper RTI (URTI), lower RTI (LRTI) and uncomplicated urinary tract infections (UTI). The study was prospective, open, and included 89 patients, from 6 months to 28 years, of both sexes, with the diagnosis of community-acquired URTI, LRTI and UTI. The treatment with cefixime was successful in 30/30 (100%) patients suffering from acute otitis media (AOM), in 10/12 (83.3%) with acute sinusitis, in 12/12 patients (100%) with pneumonia, in 31/35 (88.57) with uncomplicated UTI. The antibiotic was well tolerated. In 10 days treatment we recorded one case (1.3%) with acute gastroenteritis and two cases (2.6%) of maculopapular rash. Side-effects were transient and disappeared after finishing therapy in all three of the cases. Community-acquired infections, such as AOM, LRTI and UTI, caused by susceptible pathogens, can be treated with cefixime, as a good choice for a successful clinical response.

This study aimed to describe the burden of community-acquired acute kidney injury (AKI) in China based on a nationwide survey about AKI. Cross-sectional and retrospective study. A national sample of 2,223,230 hospitalized adult patients from 44 academic/local hospitals in Mainland China was used. AKI was defined according to the 2012 KDIGO AKI creatinine criteria or an increase or decrease in serum creatinine level of 50% during the hospital stay. Community-acquired AKI was identified when a patient had AKI that could be defined at hospital admission. The rate, cause, recognition, and treatment of community-acquired AKI were stratified according to hospital type, latitude, and economic development of the regions in which the patients were admitted. All-cause in-hospital mortality and recovery of kidney function at hospital discharge. 4,136 patients with community-acquired AKI were identified during the 2 single-month snapshots (January 2013 and July 2013). Of these, 2,020 (48.8%) had cases related to decreased kidney perfusion; 1,111 (26.9%), to intrinsic kidney disease; and 499 (12.1%), to urinary tract obstruction. In the north versus the south, more patients were exposed to nephrotoxins or had urinary tract obstructions. 536 (13.0%) patients with community-acquired AKI had indications for renal replacement therapy (RRT), but only 347 (64.7%) of them received RRT. Rates of timely diagnosis and appropriate use of RRT were higher in regions with higher per capita gross domestic product. All-cause in-hospital mortality was 7.3% (295 of 4,068). Delayed AKI recognition and being located in northern China were independent risk factors for in-hospital mortality, and referral to nephrology providers was an independent protective factor. Possible misclassification of AKI and community-acquired AKI due to nonstandard definitions and missing data for serum creatinine. The features of community-acquired AKI varied substantially in different regions of China and were closely

Anthracyclines and Acquired Long QT Syndrome. A Case Report

Carlos Rodríguez Armada

2014-12-01

Full Text Available Acquired long QT syndrome results from secondary causes and can be caused by more than 100 non-antiarrhythmic drugs. Cardiac arrest due to Torsades de pointes induced by drugs causing prolonged QT syndrome is a rare but potentially fatal event, even in hospitals. The case of a 47-year-old patient diagnosed with non-Hodgkin lymphoma admitted to the hematology department of the Dr. Gustavo Aldereguía Lima University General Hospital in Cienfuegos is presented. The patient had been previously treated with anthracyclines and developed episodes of palpitations and syncope later. The treatment included monitoring the patient, avoiding other QT prolonging agents and administrating magnesium sulfate and potassium chloride with a proper maintenance of the fluid and acid-base balance. The presentation of this case aims at motivating interest in new reports on the subject and establishing a direct causal relationship through the evidence provided by new experiences.

Listeriosis is characterized by bacteremia or meningitis. We searched for listeriosis case series and outbreak investigations published in English by 2013, and assessed the strength of evidence for foodborne acquisition among patients who ate hospital food. We identified 30 reports from 13 countries. Among the case series, the median proportion of cases considered to be hospital-acquired was 25% (range, 9%-67%). The median number of outbreak-related illnesses considered to be hospital-acquired was 4.0 (range, 2-16). All patients were immunosuppressed in 18 of 24 (75%) reports with available data. Eight outbreak reports with strong evidence for foodborne acquisition in a hospital implicated sandwiches (3 reports), butter, precut celery, Camembert cheese, sausage, and tuna salad (1 report each). Foodborne acquisition of listeriosis among hospitalized patients is well documented internationally. The number of listeriosis cases could be reduced substantially by establishing hospital policies for safe food preparation for immunocompromised patients and by not serving them higher-risk foods.

On the base of the examination of 40 patients with acquired heart diseases and 5 people without heart diseases for control determined are the most charactreristic signs of the acquired heart disease of visual observation on RPP transit (albumin of human serum labelled by sup(99m)Tc) through the heart cavities and magistral vessels. It is shown that there is a close connection between central and intracardial hemodynamics which permjts to judge on the cardiac output on the base of mean circulation time (MCT). Radioisotopic angiocardiography permits to find redistribution of lung blood flow in patients with acquired heart diseases, which can serve as indirect index of long hypertension

Rehabilitation of discourse impairments after acquired brain injury

Directory of Open Access Journals (Sweden)

Gigiane Gindri

Full Text Available ABSTRACT Language impairments in patients with acquired brain injury can have a negative impact on social life as well as on other cognitive domains. Discourse impairments are among the most commonly reported communication deficits among patients with acquired brain damage. Despite advances in the development of diagnostic tools for detecting such impairments, few studies have investigated interventions to rehabilitate patients presenting with these conditions. Objective: The aim of this study was to present a systematic review of the methods used in the rehabilitation of discourse following acquired brain injury. Methods: The PubMed database was searched for articles using the following keywords: "rehabilitation", "neurological injury", "communication" and "discursive abilities". Results: A total of 162 abstracts were found, but only seven of these met criteria for inclusion in the review. Four studies involved samples of individuals with aphasia whereas three studies recruited samples of individuals with traumatic brain injury. Conclusion: All but one article found that patient performance improved following participation in a discourse rehabilitation program.

Sterno-costo-clavicular hyperostosis (SCCH) is the most common manifestation of a syndrome, consisting of increased bone metabolism, mostly new bone formation and heterotopic ossification of fibrous tissue, which we have characterised as the acquired hyperostosis syndrome. In part I we discuss the terminology, radiological appearances, scintigraphy, clinical and laboratory findings, bacteriology, histology, nosology, complications, treatment and differential diagnosis of SCCH. Chronic recurrent multifocal osteomyelitis (CRMO) is regarded as a phaenotype of SCCH, depending on the age. CRMO occurs in children, adolescents and young adults, SCCH predominantly in middleaged and elderly adults. (orig.) [de

Portosystemic shunts are enlarged vessels that form collateral pathological pathways between the splanchnic circulation and the systemic circulation. Although their causes are multifactorial, portosystemic shunts all have one mechanism in common - increased portal venous pressure, which diverts the blood flow from the gastrointestinal tract to the systemic circulation. Congenital and acquired collateral pathways have both been described in the literature. The aim of this pictorial essay was to discuss the distinct anatomic and imaging features of portosystemic shunts, as well as to provide a robust method of differentiating between acquired portosystemic shunts and similar pathologies, through the use of illustrations and schematic drawings. Imaging of portosystemic shunts provides subclinical markers of increased portal venous pressure. Therefore, radiologists play a crucial role in the identification of portosystemic shunts. Early detection of portosystemic shunts can allow ample time to perform endovascular shunt operations, which can relieve portal hypertension and prevent acute or chronic complications in at-risk patient populations.

Consequences of radioactive fallout - Experience acquired from the Chernobyl accident

International Nuclear Information System (INIS)

Lutzko Alexandre

1997-01-01

The paper presents considerations on the nature of protection measures which were taken following the Chernobyl accident. Six methods used in Belarus aiming at reducing the radionuclide concentration in soils are listed which resulted in a reduction by a factor of 1.5 to 2 of the contamination levels in different agricultural products after 1986. A table is given showing the continuous decrease between 1986 and 1991 in the amount of sold meat and milk on market having doses exceeding the admissible values. In 1994 an increase in the ratio of contaminated products is explained as being due to investment reduction and to augmentation of transfer coefficients produced by an extremely hot summer. In conclusion it is stressed that lifting and removing the superficial layers of contaminated soils proved to be an inefficient method of decontaminating vast areas. Certain lands will not be cultivated for long as no protective action can be conducted to get them returned to agriculture. If one forgives for an instant the natural decay it seems that never one can get rid of the radioactivity. An artificial reduction methods should be supported by an international experience in the field

Objective: To evaluate the quality of the portal images acquired by computed radiography (CR) system and conventional screen-film system, respectively. Methods: Imaging plates (IP) and X-ray films ora home-devised lead phantom with a leakage of 6.45% were acquired, and modulation transfer function (MTF) curves of the both images were measured using edge method. Portal images of 40 nasopharyngeal cancer patients were acquired by IP and screen-film system respectively. Two doctors with similar experience evaluated the damage degree of petrosal bone, the receiver operating characteristic (ROC) curve of CR images and general images were drawn according to two doctors evaluation results. Results: The identification frequency of CR system and screen-film system were 1.159 and 0.806 Lp/mm respectively. For doctor one, the area under ROC curve of CR images and general images were 0.802 and 0.742 respectively. For doctor two, the area under ROC curve of CR images and general images were 0.751 and 0.600 respectively. The MTF curve and ROC curve of CR are both better than those of screen-film system. Conclusion: The image quality of CR portal imaging is much better than that of screen-film system. The utility of CR in linear accelerator for portal imaging is promising in clinic. (authors)

Development of Data Acquisition Set-up for Steady-state Experiments

Srivastava, Amit K.; Gupta, Arnab D.; Sunil, S.; Khan, Ziauddin

2017-04-01

For short duration experiments, generally digitized data is transferred for processing and storage after the experiment whereas in case of steady-state experiment the data is acquired, processed, displayed and stored continuously in pipelined manner. This requires acquiring data through special techniques for storage and on-the-go viewing data to display the current data trends for various physical parameters. A small data acquisition set-up is developed for continuously acquiring signals from various physical parameters at different sampling rate for long duration experiment. This includes the hardware set-up for signal digitization, Field Programmable Gate Arrays (FPGA) based timing system for clock synchronization and event/trigger distribution, time slicing of data streams for storage of data chunks to enable viewing of data during acquisition and channel profile display through down sampling etc. In order to store a long data stream of indefinite/long time duration, the data stream is divided into data slices/chunks of user defined time duration. Data chunks avoid the problem of non-access of server data until the channel data file is closed at the end of the long duration experiment. A graphical user interface has been developed in Lab VIEW application development environment for configuring the data acquisition hardware and storing data chunks on local machine as well as at remote data server through Python for further data access. The data plotting and analysis utilities have been developed with Python software, which provides tools for further data processing. This paper describes the development and implementation of data acquisition for steady-state experiment.

Fast attainment of computer cursor control with noninvasively acquired brain signals

Bradberry, Trent J.; Gentili, Rodolphe J.; Contreras-Vidal, José L.

2011-06-01

Brain-computer interface (BCI) systems are allowing humans and non-human primates to drive prosthetic devices such as computer cursors and artificial arms with just their thoughts. Invasive BCI systems acquire neural signals with intracranial or subdural electrodes, while noninvasive BCI systems typically acquire neural signals with scalp electroencephalography (EEG). Some drawbacks of invasive BCI systems are the inherent risks of surgery and gradual degradation of signal integrity. A limitation of noninvasive BCI systems for two-dimensional control of a cursor, in particular those based on sensorimotor rhythms, is the lengthy training time required by users to achieve satisfactory performance. Here we describe a novel approach to continuously decoding imagined movements from EEG signals in a BCI experiment with reduced training time. We demonstrate that, using our noninvasive BCI system and observational learning, subjects were able to accomplish two-dimensional control of a cursor with performance levels comparable to those of invasive BCI systems. Compared to other studies of noninvasive BCI systems, training time was substantially reduced, requiring only a single session of decoder calibration (~20 min) and subject practice (~20 min). In addition, we used standardized low-resolution brain electromagnetic tomography to reveal that the neural sources that encoded observed cursor movement may implicate a human mirror neuron system. These findings offer the potential to continuously control complex devices such as robotic arms with one's mind without lengthy training or surgery.

Tuberculosis and the acquired immune deficiency syndrome in South Brazil. The authors studied the incidence of tuberculosis in South Brazilian patients with acquired immune deficiency syndrome from January 1985 to June 1988. During this period, tuberculosis occurred in 10.3% of acquired immune deficiency syndrome patients. The socioeconomic conditions and the incidence of disease in the population were not confirmed as a potential risk for tuberculosis infection. Chest radiographs revealed pulmonary infiltrates in six patients, hilar and/or mediastinal adenopathy in three, and pleural effusion in two. The two remaining patients had pulmonary consolidation associated with other features. None of these patients presented pulmonary cavitation or radiographic findings of typical reactivation of pulmonary tuberculosis. (author) [pt

Musicality: instinct or acquired skill?

Marcus, Gary F

2012-10-01

Is the human tendency toward musicality better thought of as the product of a specific, evolved instinct or an acquired skill? Developmental and evolutionary arguments are considered, along with issues of domain-specificity. The article also considers the question of why humans might be consistently and intensely drawn to music if musicality is not in fact the product of a specifically evolved instinct.

Value-based purchasing and hospital acquired conditions: are we seeing improvement?

Science.gov (United States)

Spaulding, Aaron; Zhao, Mei; Haley, D Rob

To determine if the Value-Based Purchasing Performance Scoring system correlates with hospital acquired condition quality indicators. This study utilizes the following secondary data sources: the American Hospital Association (AHA) annual survey and the Centers for Medicare and Medicaid (CMS) Value-Based Purchasing and Hospital Acquired Conditions databases. Zero-inflated negative binomial regression was used to examine the effect of CMS total performance score on counts of hospital acquired conditions. Hospital structure variables including size, ownership, teaching status, payer mix, case mix, and location were utilized as control variables. The secondary data sources were merged into a single database using Stata 10. Total performance scores, which are used to determine if hospitals should receive incentive money, do not correlate well with quality outcome in the form of hospital acquired conditions. Value-based purchasing does not appear to correlate with improved quality and patient safety as indicated by Hospital Acquired Condition (HAC) scores. This leads us to believe that either the total performance score does not measure what it should, or the quality outcome measurements do not reflect the quality of the total performance scores measure.

1985-01-01

From 1973 to 1983, 49 Florida residents were reported with confirmed Rocky Mountain spotted fever (RMSF), 25 of whom were considered to have had Florida-acquired disease. Although there was no history of tick exposure for six of these 25 persons, all had contact with dogs or outdoor activities during the incubation period. The tick vectors of RMSF are widely distributed throughout Florida. We conclude that RMSF, although rare in Florida, can be acquired in the state. PMID:4061716

The aim was to evaluate surgical techniques and their relationship to postoperative success rate and hearing outcomes in acquired atresia of the external auditory canal. In this article, 24 patients with acquired atresia of the external auditory canal were retrospectively evaluated regarding their canal status, hearing, and postoperative success. Acquired stenosis occurs more commonly in males with a male: female ratio of 2-3:1; it seems to be a disorder affecting young adults. Previous ear surgery (13 patients, 54.2%) and external ear trauma (11 patients, 45.8%) were the main etiological factors of acquired ear canal stenosis. Mastoidectomy (12/13) and traffic accidents (8/11) comprise the majority of these etiological factors. Endaural incision is performed in 79.2% and postauricular incision for 20.8% of cases during the operation. As types of surgical approach, transcanal (70.8%), transmastoid (20.8%), and combined (8.4%) approaches are chosen. The atretic plate is generally located at the bony-cartilaginous junction (37.5%) and in the cartilaginous canal (33.3%); the bony canal is involved in a few cases only. Preserved healthy canal skin, split- or full-thickness skin grafts, or pre- or postauricular skin flaps are used to line the ear canal, but preserved healthy canal skin is preferred. The results of surgery are generally satisfactory, and complications are few if surgical principles are followed.

2010-05-01

We report the case of a 13-year-old boy with bilateral distal femoral unicameral bone cysts (UBCs) associated with acquired generalized lipodystrophy. As opposed to congenital generalized lipodystrophy, cystic bone lesions in acquired generalized lipodystrophy are rare. After radiographic and histologic confirmation of the UBCs, we performed percutaneous intramedullary decompression, curettage, and grafting. UBCs can be an important manifestation of acquired generalized lipodystrophy. Cystic bone lesions appear to be less common in acquired generalized lipodystrophy than in congenital generalized lipodystrophy, and intramedullary adipose tissue loss may be a predisposing factor for the development of bone lesions in patients with acquired generalized lipodystrophy. When evaluating a patient with lipodystrophy, doctors should recognize the clinical course may include the development of UBCs.

2009-03-01

Community-acquired pneumonia (CAP) is a major cause of death in the elderly. The age-related increase in comorbid illnesses plays a part but the effect of aging on the immune response may be equally important. We aimed to evaluate patients with CAP for evidence of a muted response to infection in elderly patients admitted to hospital compared with a younger patient group.

Most individuals who have survived an acquired brain injury present consequences affecting the sensorimotor, cognitive, affective or behavioural components. These deficits affect the proper performance of daily living activities. The aim of this study is to identify functional differences between individuals with unilateral acquired brain injury using functional independence, capacity, and performance of daily activities. Descriptive cross-sectional design with a sample of 58 people, with right-sided injury (n=14 TBI; n=15 stroke) or left-sided injury (n = 14 TBI, n = 15 stroke), right handed, and with a mean age of 47 years and time since onset of 4 ± 3.65 years. The functional assessment/functional independence measure (FIM/FAM) and the International Classification of Functioning (ICF) were used for the study. The data showed significant differences (P<.000), and a large size effect (dr=0.78) in the cross-sectional estimates, and point to fewer restrictions for patients with a lesion on their right side. The major differences were in the variables 'speaking' and 'receiving spoken messages' (ICF variables), and 'Expression', 'Writing' and 'intelligible speech' (FIM/FAM variables). In the linear regression analysis, the results showed that only 4 FIM/FAM variables, taken together, predict 44% of the ICF variance, which measures the ability of the individual, and up to 52% of the ICF, which measures the individual's performance. Gait alone predicts a 28% of the variance. It seems that individuals with acquired brain injury in the left hemisphere display important differences regarding functional and communication variables. The motor aspects are an important prognostic factor in functional rehabilitation. Copyright © 2013 Sociedad Española de Neurología. Published by Elsevier España, S.L.U. All rights reserved.

Influence of Action-Effect Associations Acquired by Ideomotor Learning on Imitation

Science.gov (United States)

Bunlon, Frédérique; Marshall, Peter J.; Quandt, Lorna C.; Bouquet, Cedric A.

2015-01-01

According to the ideomotor theory, actions are represented in terms of their perceptual effects, offering a solution for the correspondence problem of imitation (how to translate the observed action into a corresponding motor output). This effect-based coding of action is assumed to be acquired through action-effect learning. Accordingly, performing an action leads to the integration of the perceptual codes of the action effects with the motor commands that brought them about. While ideomotor theory is invoked to account for imitation, the influence of action-effect learning on imitative behavior remains unexplored. In two experiments, imitative performance was measured in a reaction time task following a phase of action-effect acquisition. During action-effect acquisition, participants freely executed a finger movement (index or little finger lifting), and then observed a similar (compatible learning) or a different (incompatible learning) movement. In Experiment 1, finger movements of left and right hands were presented as action-effects during acquisition. In Experiment 2, only right-hand finger movements were presented during action-effect acquisition and in the imitation task the observed hands were oriented orthogonally to participants’ hands in order to avoid spatial congruency effects. Experiments 1 and 2 showed that imitative performance was improved after compatible learning, compared to incompatible learning. In Experiment 2, although action-effect learning involved perception of finger movements of right hand only, imitative capabilities of right- and left-hand finger movements were equally affected. These results indicate that an observed movement stimulus processed as the effect of an action can later prime execution of that action, confirming the ideomotor approach to imitation. We further discuss these findings in relation to previous studies of action-effect learning and in the framework of current ideomotor approaches to imitation. PMID:25793755

Acquired hemophilia A (AHA), which is caused by autoantibodies against coagulation factor VIII (FVIII) is a rare, life-threatening bleeding disorder, the incidence of which appears to be increasing in Japan as the population ages. However, the clinical characteristics, treatment, and outcomes of AHA remain difficult to establish due to the rarity of this disease. We retrospectively analyzed data from 25 patients (median age 73 years; range 24-92 years; male n = 15) diagnosed with AHA between 1999 and 2015 at Gunma University Hospital. We identified autoimmune diseases and malignancy as underlying conditions in four and three patients, respectively. Factor VIII activity was significantly decreased in all patients (median 2.0%; range <1.0-8.0) by FVIII inhibitor (median 47.0 BU/mL; range 2.0-1010). Among 71 bleeding events, subcutaneous or intramuscular hemorrhage was the most prevalent. Seventeen patients required bypassing agents. Twenty-two (91.7%) of 24 patients treated with immunosuppressive agents achieved complete response (CR) during a median of 57.5 days (range 19-714 days). Although three patients (12%) relapsed and seven (28%) died of infection, none of the deaths were related to bleeding. Although most of our patients achieved CR after immunosuppressive therapy, the rate of infection-related mortality was unsatisfactorily high.

Estimates of the lifetime probability of acquiring human papillomavirus (HPV) can help to quantify HPV incidence, illustrate how common HPV infection is, and highlight the importance of HPV vaccination. We developed a simple model, based primarily on the distribution of lifetime numbers of sex partners across the population and the per-partnership probability of acquiring HPV, to estimate the lifetime probability of acquiring HPV in the United States in the time frame before HPV vaccine availability. We estimated the average lifetime probability of acquiring HPV among those with at least 1 opposite sex partner to be 84.6% (range, 53.6%-95.0%) for women and 91.3% (range, 69.5%-97.7%) for men. Under base case assumptions, more than 80% of women and men acquire HPV by age 45 years. Our results are consistent with estimates in the existing literature suggesting a high lifetime probability of HPV acquisition and are supported by cohort studies showing high cumulative HPV incidence over a relatively short period, such as 3 to 5 years.

Differential Protein Expression in Congenital and Acquired Cholesteatomas.

Directory of Open Access Journals (Sweden)

Seung-Ho Shin

Full Text Available Congenital cholesteatomas are epithelial lesions that present as an epithelial pearl behind an intact eardrum. Congenital and acquired cholesteatomas progress quite differently from each other and progress patterns can provide clues about the unique origin and pathogenesis of the abnormality. However, the exact pathogenic mechanisms by which cholesteatomas develop remain unknown. In this study, key proteins that directly affect cholesteatoma pathogenesis are investigated with proteomics and immunohistochemistry. Congenital cholesteatoma matrices and retroauricular skin were harvested during surgery in 4 patients diagnosed with a congenital cholesteatoma. Tissue was also harvested from the retraction pocket in an additional 2 patients during middle ear surgery. We performed 2-dimensional (2D electrophoresis to detect and analyze spots that are expressed only in congenital cholesteatoma and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF/MS to separate proteins by molecular weight. Protein expression was confirmed by immunohistochemical staining. The image analysis of 2D electrophoresis showed that 4 congenital cholesteatoma samples had very similar protein expression patterns and that 127 spots were exclusively expressed in congenital cholesteatomas. Of these 127 spots, 10 major spots revealed the presence of titin, forkhead transcription activator homolog (FKH 5-3, plectin 1, keratin 10, and leucine zipper protein 5 by MALDI-TOF/MS analysis. Immunohistochemical staining showed that FKH 5-3 and titin were expressed in congenital cholesteatoma matrices, but not in acquired cholesteatomas. Our study shows that protein expression patterns are completely different in congenital cholesteatomas, acquired cholesteatomas, and skin. Moreover, non-epithelial proteins, including FKH 5-3 and titin, were unexpectedly expressed in congenital cholesteatoma tissue. Our data indicates that congenital cholesteatoma origins

Acquired Duodenal Obstruction in Children

Directory of Open Access Journals (Sweden)

Jen-Hung Chien

2008-10-01

Full Text Available Traumatic intramural hematoma of the duodenum is a rare cause of acquired duodenal obstruction in children, and a high degree of suspicion is therefore required to make an early and accurate diagnosis. We report a 6-year-old boy whose epigastrium was impacted by the handlebar of his bicycle during a traffic accident. The boy then experienced epigastralgia. Six days later, progressive bilious vomiting suggestive of gastrointestinal obstruction was noted. Imaging studies revealed a large hematoma extending from the fourth portion of the duodenum to the jejunum. Conservative methods of treatment failed to manage his condition. He underwent laparoscopic surgery to evacuate the hematoma. We also report a case of duodenal obstruction in a previously healthy 2-year-old girl who presented for the first time with acute symptoms of proximal intestinal obstruction. Contrast examinations showed apparent barium retention over the stomach and proximal duodenum. She underwent surgery due to persistent obstruction, and a mushroom-like foreign body was detected embedded in the orifice of the windsock duodenal web. After duodenoduodenostomy and removal of the bezoar, she had a smooth recovery and tolerated feeding well. We conclude that blunt abdominal trauma and incomplete duodenal obstruction, such as that caused by duodenal web, should be considered as possible causes of acquired proximal gastrointestinal obstruction in previously healthy children, despite their rarity.

[The AMY experiment

International Nuclear Information System (INIS)

1989-01-01

The AMY experiment is one of three major experiments at TRISTAN which is studying the states the matter produced in electron positron annihilations in the center of mass energy range of 50--65GeV. It provides information between the lower energy facilities such as PEP and PETRA and the new facilities SLC and LEP which are designed to operate in the region of the Z 0 mass near 90GeV. In the region of the AMY experiment, interaction cross sections are near their minimum of about 100pb, making it difficult to acquire large data samples during typical running cycles. This last year has seen an accumulation of about 10---12pb -1 of integrated luminosity in the energy range from 58 to 61.7GeV. Despite this limited data sample, the AMY experiment has been extremely active in attempting to extract the minimum amount of information from the data. Some of the most significant results are discussed in this paper. 9 refs

MEASUREMENT OF LARGE-SCALE SOLAR POWER PLANT BY USING IMAGES ACQUIRED BY NON-METRIC DIGITAL CAMERA ON BOARD UAV

R. Matsuoka

2012-07-01

Full Text Available This paper reports an experiment conducted in order to investigate the feasibility of the deformation measurement of a large-scale solar power plant on reclaimed land by using images acquired by a non-metric digital camera on board a micro unmanned aerial vehicle (UAV. It is required that a root mean squares of errors (RMSE in height measurement should be less than 26 mm that is 1/3 of the critical limit of deformation of 78 mm off the plane of a solar panel. Images utilized in the experiment have been obtained by an Olympus PEN E-P2 digital camera on board a Microdrones md4-1000 quadrocopter. The planned forward and side overlap ratios of vertical image acquisition have been 60 % and 60 % respectively. The planned flying height of the UAV has been 20 m above the ground level and the ground resolution of an image is approximately 5.0 mm by 5.0 mm. 8 control points around the experiment area are utilized for orientation. Measurement results are evaluated by the space coordinates of 220 check points which are corner points of 55 solar panels selected from 1768 solar panels in the experiment area. Two teams engage in the experiment. One carries out orientation and measurement by using 171 images following the procedure of conventional aerial photogrammetry, and the other executes those by using 126 images in the manner of close range photogrammetry. The former fails to satisfy the required accuracy, while the RMSE in height measurement by the latter is 8.7 mm that satisfies the required accuracy. From the experiment results, we conclude that the deformation measurement of a large-scale solar power plant on reclaimed land by using images acquired by a nonmetric digital camera on board a micro UAV would be feasible if points utilized in orientation and measurement have a sufficient number of bundles in good geometry and self-calibration in orientation is carried out.

Method to acquire regions of fruit, branch and leaf from image of red apple in orchard

Lv, Jidong; Xu, Liming

2017-07-01

This work proposed a method to acquire regions of fruit, branch and leaf from red apple image in orchard. To acquire fruit image, R-G image was extracted from the RGB image for corrosive working, hole filling, subregion removal, expansive working and opening operation in order. Finally, fruit image was acquired by threshold segmentation. To acquire leaf image, fruit image was subtracted from RGB image before extracting 2G-R-B image. Then, leaf image was acquired by subregion removal and threshold segmentation. To acquire branch image, dynamic threshold segmentation was conducted in the R-G image. Then, the segmented image was added to fruit image to acquire adding fruit image which was subtracted from RGB image with leaf image. Finally, branch image was acquired by opening operation, subregion removal and threshold segmentation after extracting the R-G image from the subtracting image. Compared with previous methods, more complete image of fruit, leaf and branch can be acquired from red apple image with this method.

Background: Hyponatremia is the most commonly encountered electrolyte disorder in children. In our country the epidemiology of hospital acquired hyponatremia has hardly ever been explored whereas the administration of hypotonic IV fluids is widely practiced here. Therefore we pioneered to conduct this study to determine the frequency of hospital acquired hyponatremia. Method: This was a cross sectional study carried out at Aga Khan University Hospital, Karachi in paediatric ward and ICU over a period of 12 months. All children (>1 month and <15 years of age) admitted in paediatric units and on maintenance IV fluids who had serum sodium level measured on admission were included in the study and followed to identify patients who had a drop in serum sodium during hospitalization. Informed consent was taken from parents and collected data was recorded on a proforma. Results: A total of 865 patients were enrolled in the study. Hyponatremia was recorded in 405 patients on admission (46.8 percentage) while hospital acquired hyponatremia was documented in 240. children (27.7 percentage). Out of these 142 (59.2 percentage) were male and 98 (40.8 percentage) were female. Mean age of children in hospital acquired hyponatremia group was 60.67 months. Severity of hospital acquired hyponatremia was recorded as mild in 191 (79.6 percentage), moderate in 35 (14.6 percentage) and severe in 14 (5.8) children. Major disease categories included gastrointestinal disorder (30.4 percentage), respiratory illness (12.5 percentage), oncological disease (16.3 percentage), cardiovascular disease (11.7 percentage), infectious disease (9.2 percentage) and neurological illness (8.3 percentage). Conclusion: Hospital acquired hyponatremia is frequently encountered in our hospitalized children with majority of them receiving hypotonic IV solutions. (author)

Full Text Available PURPOSE: Toxoplasmosis is the most common cause of posterior infectious uveitis worldwide. It is often impossible to determine its congenital or acquired nature. Interleukin-2 (IL-2 in peripheral blood has been described as a possible marker for acquired toxoplasmosis. The purpose of this study is to evaluate the histopathological characteristics of ocular toxoplasmosis cases using CD25 as a marker for the expression of interleukin-2. METHODS: Ten formalin-fixed, paraffin-embedded enucleated globes from ten immunocompetent patients with clinical diagnosis of toxoplasmosis were evaluated. Four patients had the acquired form of ocular toxoplasmosis (positive IgM while six were IgM negative and IgG positive for toxoplasmosis. Histopathological slides were reviewed for the extension of the retinal necrosis, number of toxo cysts, the granulomatous inflammatory reaction, the presence of T and B cells within the choroid and the IL-2 expression. Immunohistochemistry using monoclonal antibodies was performed to observe the expression of CD4, CD8, CD20, CD25, and CD68. RESULTS: The histopathological evaluation disclosed no differences between acquired and the other ocular toxoplasmosis cases regarding the characteristics studied. However, CD25 showed a higher expression of IL-2 on the 4 acquired cases of ocular toxoplasmosis compared to the remainders. CONCLUSIONS: To the best of our knowledge, this is the first report showing that the use of CD25 as a marker for interleukin-2 could differentiate acquired ocular toxoplasmosis.

Background and purpose: Cellular radioresistance is a major impediment to effective radiotherapy. Here, we demonstrated that long-term exposure to fractionated radiation conferred acquired radioresistance to tumor cells due to AKT-mediated enhanced aerobic glycolysis. Material and methods: Two human tumor cell lines with acquired radioresistance were established by long-term exposure to fractionated radiation with 0.5 Gy of X-rays. Glucose uptake was inhibited using 2-deoxy-D-glucose, a non-metabolizable glucose analog. Aerobic glycolysis was assessed by measuring lactate concentrations. Cells were then used for assays of ROS generation, survival, and cell death as assessed by annexin V staining. Results: Enhanced aerobic glycolysis was shown by increased glucose transporter Glut1 expression and a high lactate production rate in acquired radioresistant cells compared with parental cells. Inhibiting the AKT pathway using the AKT inhibitor API-2 abrogated these phenomena. Moreover, we found that inhibiting glycolysis with 2-deoxy-D-glucose suppressed acquired tumor cell radioresistance. Conclusions: Long-term fractionated radiation confers acquired radioresistance to tumor cells by AKT-mediated alterations in their glucose metabolic pathway. Thus, tumor cell metabolic pathway is an attractive target to eliminate radioresistant cells and improve radiotherapy efficacy

2006-08-01

Full Text Available Background: Community-acquired pneumonia could be a life-threatening condition especially in elderly patients. The factors influencing the outcome in elderly patients are thought to be different from those in young adults. We compared the clinical and paraclinical profiles in elderly and nonelderly patients with community-acquired pneumonias. Methods: In this cross-sectional study, seventy nine patients who were hospitalized with community acquired pneumonia over a period of one year were included. Patients' medical records were reviewed; and data related to comorbid conditions, signs and symptoms, laboratory and radiographic findings were gathered using a checklist. Results: The clinical features, laboratory parameters and complications from pneumonia were almost similar in 41 elderly (group I, age ≥65years and 38 young (group II, age<65years subjects. Delirium was seen more in elderly group (p=0.05. The average body temperature and pulse rate were significantly higher in nonelderly group. Sixty one percent of elderly patients and 21% of young patients have Po2 less than 60 (p=0.02. Smoking (29.1%, neurological disturbances (19%, congestive heart failure (15.2%, chronic obstructive pulmonary disease and diabetes mellitus (13.9% were associated comorbidities in both groups. In non elderly group, immune compromise and IV drug use were more common as underlying comorbid conditions. Two of three mortalities were due to elder patients. Conclusion: Community acquired pneumonia could have more serious clinical and abnormal laboratory features in the elderly than younger patients. Mortality rate may be higher in older patients. Comorbid conditions are frequently seen in both elderly and nonelderly patients with community acquired pneumonia, but IV drug use and immune compromise are more frequent in nonelderly patients.

The role of disability self-concept in adaptation to congenital or acquired disability.

Science.gov (United States)

Bogart, Kathleen R

2014-02-01

Current theories of adaptation to disability do not address differences in adaptation to congenital or acquired disability. Although people with congenital disabilities are generally assumed to be better adapted than people with acquired disabilities, few studies have tested this, and even fewer have attempted to explain the mechanisms behind these differences. This study tested the proposition that whether a disability is congenital or acquired plays an important role in the development of the disability self-concept (consisting of disability identity and disability self-efficacy), which in turn, affects satisfaction with life. It was predicted that disability self-concept would be better developed among people with congenital, compared with acquired disabilities, predicting greater satisfaction with life in those with acquired conditions. 226 participants with congenital and acquired mobility disabilities completed a cross-sectional online questionnaire measuring satisfaction with life, self-esteem, disability identity, disability self-efficacy, and demographic information. Self-esteem, disability identity, disability self-efficacy, and income were significant predictors of satisfaction with life. Congenital onset predicted higher satisfaction with life; disability identity and disability self-efficacy, but not self-esteem, partially mediated the relationship. Findings highlight the distinction between adaptation to congenital versus acquired disability and the importance of disability self-concept, which are underresearched constructs. Results suggest that rather than attempting to "normalize" individuals with disabilities, health care professionals should foster their disability self-concept. Possible ways to improve disability self-concept are discussed, such as involvement in the disability community and disability pride. PsycINFO Database Record (c) 2014 APA, all rights reserved.

2011-12-01

Chromosomal imbalances can result from numerical or structural anomalies. Numerical chromosomal abnormalities are often referred to as aneuploid conditions. This article focuses on the occurrence of constitutional and acquired autosomal aneuploidy in humans. Topics covered include frequency, mosaicism, phenotypic findings, and etiology. The article concludes with a consideration of anticipated advances that might allow for the development of screening tests and/or lead to improvements in our understanding and management of the role that aneuploidy plays in the aging process and acquisition of age-related and constitutional conditions.

Data acquisition system for steady state experiments at multi-sites

International Nuclear Information System (INIS)

Nakanishi, H.; Emoto, M.; Nagayama, Y.

2010-11-01

A high-performance data acquisition system (LABCOM system) has been developed for steady state fusion experiments in Large Helical Device (LHD). The most important characteristics of this system are the 110 MB/s high-speed real-time data acquisition capability and also the scalability on its performance by using unlimited number of data acquisition (DAQ) units. It can also acquire experimental data from multiple remote sites through the 1 Gbps fusion-dedicated virtual private network (SNET) in Japan. In LHD steady-state experiments, the DAQ cluster has established the world record of acquired data amount of 90 GB/shot which almost reaches the ITER data estimate. Since all the DAQ, storage, and data clients of LABCOM system are distributed on the local area network (LAN), remote experimental data can be also acquired simply by extending the LAN to the wide-area SNET. The speed lowering problem in long-distance TCP/IP data transfer has been improved by using an optimized congestion control and packet pacing method. Japan-France and Japan-US network bandwidth tests have revealed that this method actually utilize 90% of ideal throughput in both cases. Toward the fusion goal, a common data access platform is indispensable so that detailed physics data can be easily compared between multiple large and small experiments. The demonstrated bilateral collaboration scheme will be analogous to that of ITER and the supporting machines. (author)

Community-acquired pneumonia: 2012 history, mythology, and science.

Science.gov (United States)

Donowitz, Gerald R

2013-01-01

Pneumonia remains one of the major disease entities practicing physicians must manage. It is a leading cause of infection-related morbidity and mortality in all age groups, and a leading cause of death in those older than 65 years of age. Despite its frequency and importance, clinical questions have remained in the therapy of community-acquired pneumonia including when to start antibiotics, when to stop them, who to treat, and what agents to use. Answers to these questions have involved historical practice, mythology, and science-sometimes good science, and sometimes better science. How clinical decisions are made for patients with community-acquired pneumonia serves as an illustrative model for other problem areas of medicine and allows for insight as to how clinical decisions have been made and clinical practice established.

Acquired immunodeficiency syndrome associated with blood-product transfusions

Jett, J.R.; Kuritsky, J.N.; Katzmann, J.A.; Homburger, H.A.

1983-01-01

A 53-year-old white man had fever, malaise, and dyspnea on exertion. His chest roentgenogram was normal, but pulmonary function tests showed impaired diffusion capacity and a gallium scan showed marked uptake in the lungs. Results of an open-lung biopsy documented Pneumocystis carinii pneumonia. Immunologic test results were consistent with the acquired immunodeficiency syndrome. The patient denied having homosexual contact or using intravenous drugs. Twenty-nine months before the diagnosis of pneumocystis pneumonia was made, the patient had had 16 transfusions of whole blood, platelets, and fresh-frozen plasma during coronary artery bypass surgery at another medical center. This patient is not a member of any currently recognized high-risk group and is believed to have contracted the acquired immunodeficiency syndrome from blood and blood-product transfusions

Utilizing ZFS for the Storage of Acquired Data

2009-01-01

Every day, the amount of data that is acquired from plasma experiments grows dramatically. It has become difficult for systems administrators to keep up with the growing demand for hard drive storage space. In the past, project storage has been supplied using UNIX filesystem (ufs) partitions. In order to increase the size of the disks using this system, users were required to discontinue use of the disk, so the existing data could be transferred to a disk of larger capacity or begin use of a completely new and separate disk, thus creating a segmentation of data storage. With the application of ZFS pools, the data capacity woes are over. ZFS provides simple administration that eliminates the need to unmount to resize, or transfer data to a larger disk. With a storage limit of 16 Exabytes (1018), ZFS provides immense scalability. Utilizing ZFS as the new project disk file system, users and administrators can eliminate time wasted waiting for data to transfer from one hard drive to another, and also enables more efficient use of disk space, as system administrators need only allocate what is presently required. This paper will discuss the application and benefits of using ZFS as an alternative to traditional data access and storage in the fusion environment.

Genetic Determinism and the Innate-Acquired Distinction in Medicine

Science.gov (United States)

2009-01-01

This article illustrates in which sense genetic determinism is still part of the contemporary interactionist consensus in medicine. Three dimensions of this consensus are discussed: kinds of causes, a continuum of traits ranging from monogenetic diseases to car accidents, and different kinds of determination due to different norms of reaction. On this basis, this article explicates in which sense the interactionist consensus presupposes the innate–acquired distinction. After a descriptive Part 1, Part 2 reviews why the innate–acquired distinction is under attack in contemporary philosophy of biology. Three arguments are then presented to provide a limited and pragmatic defense of the distinction: an epistemic, a conceptual, and a historical argument. If interpreted in a certain manner, and if the pragmatic goals of prevention and treatment (ideally specifying what medicine and health care is all about) are taken into account, then the innate–acquired distinction can be a useful epistemic tool. It can help, first, to understand that genetic determination does not mean fatalism, and, second, to maintain a system of checks and balances in the continuing nature–nurture debates. PMID:20234831

2006-01-01

Mandatory reporting and disclosure of health care-acquired infections have resulted in controversy over the perceived notion that consumers will not understand how to interpret data and that such information may negatively influence utilization of hospitals. The objective was to determine consumers' attitudes about health care-acquired infections, hand hygiene practices, and patient empowerment. A telephone survey based on a random digit dialing sample of all households in the United States was conducted. Consumers were asked about choosing a hospital, hand hygiene practices, and health care-acquired infections. Some 94% of respondents rated environmental cleanliness as very important. Hospital infection rates would influence decision making for 93% of consumers. Four in 5 consumers said they would ask their health care worker to wash and sanitize his or her hands. Our findings strongly suggest that (1) consumers will use infection data in selecting and/or leaving a hospital system and (2) consumers are ready to be empowered with information to ensure a positive outcome.

2006-01-01

Full Text Available Background: Although prevalence of MRSA strains is reported to be increasing, there are no studies of their prevalence in community-acquired primary pyodermas in western India. Aims: This study aimed at determining the prevalence of MRSA infection in community-acquired primary pyodermas. Methods: Open, prospective survey carried out in a tertiary care hospital in Mumbai. Materials and Methods: Eighty-six patients with primary pyoderma, visiting the dermatology outpatient, were studied clinically and microbiologically. Sensitivity testing was done for vancomycin, sisomycin, gentamicin, framycetin, erythromycin, methicillin, cefazolin, cefuroxime, penicillin G and ciprofloxacin. Phage typing was done for MRSA positive strains. Results : The culture positivity rate was 83.7%. Staphylococcus aureus was isolated in all cases except two. Barring one, all strains of Staphylococcus were sensitive to methicillin. Conclusions: Methicillin resistance is uncommon in community-acquired primary pyodermas in Mumbai. Treatment with antibacterials active against MRSA is probably unwarranted for community-acquired primary pyodermas.

to characterize the seropositive elderly for the Human Immunodeficiency Virus and Acquired Immunodeficiency Syndrome (HIV/AIDS) in their socio-demographic aspects; to understand how the elderly take care of themselves from the diagnosis of HIV/AIDS. Qualitative, descriptive, exploratory research conducted at a Voluntary Counseling and Testing Center with 10 elderly people receiving treatment for HIV/AIDS. The data were analyzed according to the content analysis. Data show the elderly people's lack of knowledge about HIV/AIDS transmission, the experience of being elderly and having HIV/AIDS, caring for oneself and life after diagnosis of HIV/AIDS in their daily lives. Final considerations: The diagnosis of HIV/AIDS seropositivity in the elderly generates a blend of feelings and fears that lead to food changes, adherence to treatment and the renunciation of daily and social habits, manifested as ways of self-care.

Kaposi's sarcoma is frequently found in association with acquired immunodeficiency syndrome (AIDS). We report on radiotherapy for patients with AIDS-related Kaposi's sarcoma at Tokyo Metropolitan Komagome Hospital. Between April 1991 and May 1997, radiotherapy was given to 11 lesions in eight men with AIDS-related Kaposi's sarcoma to relieve their symptoms. The lesions involved the head and neck region, the legs, and the gastrointestinal tract. Radiotherapy was carried out with 4-MV photon through parallel opposed field or high energy electrons. Total doses ranged from 20 to 38 Gy, with a median of 30 Gy, delivered in 2- to 3-Gy fractions. Four patients were given other treatments prior to the radiotherapy. Acute reaction was evaluated according to the modified acute radiation morbidity scoring criteria of the Radiation Therapy Oncology Group (RTOG). Radiotherapy had relieved the symptoms in all patients at completion of this therapy. Lesions that involved the hard palate and vocal cords had completely disappeared. The lesions that received radiotherapy were controlled without symptoms until the patients died. Patients who had the head and neck region treated exhibited severe acute mucosal reaction (at a dose of 30 Gy, there was grade 2 morbidity by modified RTOG criteria, in two patients, and grade 3 in three patients) although the radiation therapy was completed for these patients. Radiotherapy promises a favorable outcome for symptom relief in AIDS-related Kaposi's sarcoma. (author)

Full Text Available http://dx.doi.org/10.5007/2175-8026.2015v68n2p115 This paper aims at tackling the question as to why Sula as a social nonconformist and sexual dissident ends up as an avatar of evil, a powerless victim of witch-hunt and eventually a scapegoat for the decline and misfortunes of her community. To facilitate this critical task, this paper shall irst apply Michel Foucault’s genealogy of “the body as the bearer of pleasure and desire” as laid out in Abnormal to illustrate that Christian folks in Sula’s community interpret Sula’s nonconformity as evil and treat her as a danger to their social order. Thus, this paper argues that the black folks’ ostracism of Sula betokens their mass hysteria and witch-hunt to exorcise their community of danger and evil. Moreover, this paper suggests that Sula is gendered and racialized as a black witch and symbolically executed. In conclusion, this paper contends that an identiication of body with lesh, a phallocentric gender ideology and race bias converge into the black folk’s association of Sula with a witch and a danger and their subsequent victimization of sula as a scapegoat for all the misfortunes of their community.

How Do Persons with Mild Acquired Cognitive Impairment Use Information and Communication Technology and E-Services? Results from a Swedish National Survey.

Mild acquired cognitive impairment is a term used to describe a sub-group of persons with mild cognitive impairment who are expected to reach a stable cognitive level over time. One tactic that can be considered for further developing treatment for this group is the use of information and communication technology and e-services. The purpose of this study was to investigate the current use of regular e-services and social media by this group as well as their user experiences. Data were collected through a self-administered survey and analyzed using quantitative methods. The questionnaire included questions regarding the participants' use of and experience with e-services. Categorization of e-services was based on and cross-validated with the International Classification of Functioning, Disability and Health (ICF). To estimate participants' degree and type of impairment, the Cognitive Failure Questionnaire (CFQ), measuring cognitive difficulties in performing everyday tasks, was added. In total, 282 persons with acquired brain injury participated in the survey. The participants' CFQ scores showed that they were suffering from mild to moderate cognitive impairments, most often acquired from traumatic brain injuries (40%). The majority (89%) used e-services in different categories whereof the most popular and essential ones were communication services (59%) and banking (39%) services. Participants with higher total CFQ scores (>58) used more e-services in most of the categories compared to participants with lower scores (services to be trustworthy and supportive in different contexts. The usage of electronic devices decreased by age with the exception of electronic tablets that were used by older participants approximately as frequently as by other age groups. Although persons with mild to moderate acquired brain injury used various e-services that are not customized for them, very few participants used self-care health services (apps) and readers (e-readers).

Starn, Emily S; Hampe, Holly; Cline, Thomas

Health care facility-acquired Clostridium difficile infections (HCFA-CDI) have increased over the last several decades despite facilities developing protocols for prescribing probiotics with antibiotics to prevent HCFA-CDI. The literature does not consistently support this. A retrospective medical record review evaluated the care effectiveness of this practice. Care effectiveness was not found; patients receiving probiotics with antibiotics were twice as likely to develop HCFA-CDI (P = .004). Except with glycopeptides, patients were 1.88 times less likely to experience HCFA-CDI (P = .05).

Acquired immunologic tolerance in chimeras and histocompatibility factors in cattle and their relationship to those in humans. Final report

International Nuclear Information System (INIS)

Stone, W.H.

1976-03-01

During the course of this project we have studied 35 pairs of chimeric cattle twins. It is now clear that fractionated doses of whole-body 60 Co irradiation can cause marked shifts in the proportions of the two erythrocyte populations that make up the chimeric mixture. However, it has not been possible to eliminate one of the two cell types and thus abrogate the acquired immunologic tolerance. The results of our extensive skin-grafting experiments are remarkable because they show that a chimeric twin may mount a sufficient immune response to reject its cotwin's skin while remaining completely tolerant to erythropoietic elements of its cotwin. In conjunction with these studies, we have acquired sufficient data to define a major histocompatibility locus in cattle using alloimmune anti-lymphocyte typing sera as well as the mixed lymphocyte culture technic. This project has also yielded a considerable number of new immunogenetic parameters for cattle, monkeys and birds. Such parameters are useful for basic and applied studies in immunology

Landmark memories are more robust when acquired at the nest site than en route: experiments in desert ants.

Foraging desert ants, Cataglyphis fortis, encounter different sequences of visual landmarks while navigating by path integration. This paper explores the question whether the storage of landmark information depends on the context in which the landmarks are learned during an ant's foraging journey. Two experimental set-ups were designed in which the ants experienced an artificial landmark panorama that was placed either around the nest entrance (nest marks) or along the vector route leading straight towards the feeder (route marks). The two training paradigms resulted in pronounced differences in the storage characteristics of the acquired landmark information: memory traces of nest marks were much more robust against extinction and/or suppression than those of route marks. In functional terms, this result is in accord with the observation that desert ants encounter new route marks during every foraging run but always pass the same landmarks when approaching the nest entrance.

1988-08-01

Sixty-two patients were treated by some combination of cryotherapy and surgery with an average follow-up of 3.3 years for one of the following diseases: focal or diffuse flat conjunctival primary acquired melanosis (PAM) with atypia but without a nodule of melanoma (10 cases); unifocal malignant melanoma with or without focal or diffuse PAM (30 cases); and multinodular/multicentric melanoma with and without PAM (22 cases). Of the ten patients who had PAM with atypia, invasive nodules of malignant melanoma did not develop. A second treatment was required to control the disease in four of the ten patients with extensive or diffuse lesions, and one has mild persistent disease. Of the 30 patients with unifocal nodules of malignant melanoma, 27 remained free of recurrence after one treatment, and 2 are asymptomatic after two treatments. One patient with a thick nodule at presentation required a parotidectomy and radical neck dissection for cervical metastases after recurrence in the conjunctival sac. In the group of 22 patients with multinodular malignant melanoma, only two did not have recurrent disease after one treatment. Of those who received multiple therapies, seven remained free of recurrence for at least 2 years after the last treatment; regional or distant metastases developed in nine; four required exenteration; and eight died. Conjunctival adjunctive cryotherapy avoids exenteration in extensive lesions of pure PAM and in unifocal melanoma, but even after multiple therapies, multinodular malignant melanoma had a 45% rate of metastasis. Metastasis was related to the presence of PAM sine pigmento in four patients (microscopically but not clinically detectable PAM); to the location of the nodules (9 of 10 patients who experienced metastases had forniceal, palpebral, and/or caruncular nodules); to the thickness or depth of invasion of the nodules (greater than 2 mm); and to the development of intralymphatic spread ("in-transit" local metastasis) within the

First, we explain why Genetic Algorithms (GAs), inspired by the Modern Synthesis, do not accurately model biological evolution, being rather an artificial version of artificial, rather than natural selection. Being focused on optimisation, we propose two improvements of GAs, with the aim to successfully generate adapted, desired behaviour. The first one concerns phylogenetic grounding of meaning, a way to avoid the Symbol Grounding Problem. We give a definition of Phylogenetically Acquired Re...

Severe Recurrent Achalasia Cardia Responding to Treatment of Severe Autoimmune Acquired Haemophilia

Directory of Open Access Journals (Sweden)

H. Al-Jafar

2012-09-01

Full Text Available Acquired haemophilia A and severe acquired achalasia are both very rare conditions with unknown aetiology. Haemophilia A is a haemorrhagic disease induced by deficiency or malfunction of coagulation factor VIII. Congenital haemophilia is an inherited disease transmitted by the mother through X-linked inheritance and primarily affects males. However, acquired haemophilia A is a serious, sudden-onset, autoimmune disease that affects either sex. In addition, achalasia is a disease of the oesophagus caused by abnormal function of the nerves and muscles. It causes swallowing difficulties due to the inability of the lower oesophageal sphincter to relax during swallowing, leading to dysphagia, regurgitation and chest pain. In this report, we describe the case of a patient with severe, newly diagnosed, acquired haemophilia A with long-standing, recurrent achalasia; the achalasia had recurred 3 times despite complete and proper surgical fixation. Acquired haemophilia A is treated with immunosuppressive therapy. High-dose steroid therapy was administered for 7 months, during which the patient responded well; moreover, the achalasia did not recur for more than 2 years. The response of the achalasia to immunosuppressive therapy suggests that achalasia may be an autoimmune disorder and that there may be an association between both diseases. The findings of the present case suggest that achalasia may favourably respond to steroid therapy as a first-line treatment prior to surgery.

A positive outcome of the modern welfare state is prolonged life expectancy. In Sweden, the expected life span has increased with approximatively 25 years during the 20th century [Statistics Sweden]. However, ageing is associated with an increased risk for acquiring cognitive and physical disabilities. This study is based on anonymized interviews with groups of older persons who experience cognitive problems and relatives. The interviewees were asked about everyday activities like shopping groceries, clothes or other necessities. The interviewees identified problems and described a series of strategies for coping. This paper uses fictionalized characters to present problems and coping strategies that the interviewees use to overcome cognitive challenges when shopping groceries. The strategies range from complete withdrawal, an increased dependency on proxies to the development of elaborate techniques to mask their problem and obtain assistance. Following the current trend in the design of the Swedish sales environment - large scale, abundance of goods and Maslowian strategies for making people stay longer (and spend more money) - accessibility in the built environment is often an absent friend.

Principles of Antibiotic Management of Community-Acquired Pneumonia.

Science.gov (United States)

Bender, Michael T; Niederman, Michael S

2016-12-01

Community-acquired pneumonia (CAP) encompasses a broad spectrum of disease severity and may require outpatient, inpatient, or intensive care management. Successful treatment hinges on expedient delivery of appropriate antibiotic therapy tailored to both the likely offending pathogens and the severity of disease. This review summarizes key principles in starting treatment and provides recommended empiric therapy regimens for each site of care. In addition, we discuss the antimicrobial and anti-inflammatory role macrolides play in CAP, as well as specific information for managing individual CAP pathogens such as community-acquired methicillin-resistant Staphylococcus aureus and drug-resistant Streptococcus pneumoniae . We also examine several novel antibiotics being developed for CAP and review the evidence guiding duration of therapy and current best practices for the transition of hospitalized patients from intravenous antibiotics to oral therapy.

Highlights: • CT with multiplanar reformations can accurately display the sigmoid platet dehiscence. • The prevalence of sigmoid plate dehiscence was no significant difference among different age groups. • The size of sigmoid plate bony defects were not statistically different among different age groups. • The sigmoid plate dehiscence is more commonly a congenital than an acquired condition. - Abstract: Background and purpose: The imaging features of sigmoid plate dehiscence-induced pulsatile tinnitus have been presented. The origin of the sigmoid plate dehiscence, however, remains unclear. Our aim was to assess the prevalence and extent of sigmoid plate dehiscence on computed tomography (CT) images in multiple age groups to determine whether this condition is more likely to be congenital or acquired. Materials and methods: We retrospectively reviewed contrast-enhanced CT images of sigmoid plates of temporal bones in 504 patients. Each temporal bone was characterized as normal or dehiscent. Patients were then subcategorized into four age groups, and the prevalence and extent of dehiscent sigmoid plates in each group were calculated and compared. Results: Overall, 80 patients had sigmoid plate dehiscence, nine of whom had it bilaterally. In successively older age groups, the prevalences of sigmoid plate dehiscence were 18.9%, 20.1%, 14.5%, and 12.7%, respectively. Respective average anteroposterior bony defect diameters were 3.7 ± 1.7, 3.0 ± 1.3, 3.1 ± 1.5, and 3.0 ± 1.1 mm. Respective average vertical bony defect diameters were 3.6 ± 2.3, 2.6 ± 1.2, 3.2 ± 1.5, and 3.0 ± 1.7 mm. The prevalence and extent of sigmoid plate dehiscence were not statistically different among the four age groups. Conclusions: The similar radiologic prevalence and extent of dehiscent sigmoid plates among the age groups suggest that the dehiscence is more commonly a congenital than an acquired condition.

To evaluate the current patient care practices that address the predisposing and precipitating factors contributing to the prevention of hospital-acquired delirium in the elderly. Prospective cohort (observational) study. Patients 65 years of age and older who were admitted to medical teaching units at the University of Alberta Hospital in Edmonton over a period of 7 months and who were at risk of delirium. Medical teaching units at the University of Alberta. Demographic data and information on predisposing factors for hospital-acquired delirium were obtained for all patients. Documented clinical practices that likely prevent common precipitants of delirium were also recorded. Of the 132 patients enrolled, 20 (15.2%) developed hospital-acquired delirium. At the time of admission several predisposing factors were not documented (eg, possible cognitive impairment 16 [12%], visual impairment 52 [39.4%], and functional status of activities of daily living 99 [75.0%]). Recorded precipitating factors included catheter use, screening for dehydration, and medications. Catheters were used in 35 (26.5%) patients, and fluid intake-and-output charting assessed dehydration in 57 (43.2%) patients. At the time of admission there was no documentation of hearing status in 69 (52.3%) patients and aspiration risk in 104 (78.8%) patients. After admission, reorientation measures were documented in only 16 (12.1%) patients. Although all patients had brief mental status evaluations performed once daily, this was not noted to occur twice daily (which would provide important information about fluctuation of mental status) and there was no formal attention span testing. In this study, hospital-acquired delirium was also associated with increased mortality (P < .004), increased length of stay (P < .007), and increased institutionalization (P < .027). Gaps were noted in patient care practices that might contribute to hospital-acquired delirium and also in measures to identify the development

Acquired heart conditions in adults with congenital heart disease: a growing problem.

Science.gov (United States)

Tutarel, Oktay

2014-09-01

The number of adults with congenital heart disease is increasing due to the great achievements in the field of paediatric cardiology, congenital heart surgery and intensive care medicine over the last decades. Mortality has shifted away from the infant and childhood period towards adulthood. As congenital heart disease patients get older, a high prevalence of cardiovascular risk factors is encountered similar to the general population. Consequently, the contribution of acquired morbidities, especially acquired heart conditions to patient outcome, is becoming increasingly important. Therefore, to continue the success story of the last decades in the treatment of congenital heart disease and to further improve the outcome of these patients, more attention has to be given to the prevention, detection and adequate therapy of acquired heart conditions. The aim of this review is to give an overview about acquired heart conditions that may be encountered in adults with congenital heart disease. Published by the BMJ Publishing Group Limited.

A narrative analysis of a speech pathologist's work with Indigenous Australians with acquired communication disorders.

Hersh, Deborah; Armstrong, Elizabeth; Bourke, Noni

2015-01-01

To explore in detail the narrative of a speech pathologist (SP) working with Indigenous Australian clients with acquired communication disorders following stroke or brain injury. There is some evidence that Indigenous clients do not find speech pathology rehabilitation to be culturally appropriate but, currently, there is very little published on the nature of this service or the experiences of SPs who provide this rehabilitation. This research uses both thematic and structural narrative analysis of data from a semi-structured, in-depth interview with a SP to examine the adaptations that she made to address the needs of her adult neurological caseload of (mainly) Indigenous Australians from both urban and remote regions. The thematic analysis resulted in a core theme of flexibility and four other sub-themes: awareness of cultural context, client focus/person-centredness, being practical and working ethically. The structural narrative analysis allowed insight into the nature of clinical reasoning in a context lacking predictability and where previous clinical certainties required adaptation. Individual, detailed narratives are useful in exposing the challenges and clinical reasoning behind culturally sensitive practice. Implications for Rehabilitation Speech pathologists (SPs) can learn from hearing the clinical stories of colleagues with experience of providing rehabilitation in culturally diverse contexts, as well as from ongoing training in culturally competent and safe practices. Such stories help bridge understanding from the general to the particular. SPs working with Indigenous Australians with acquired communication disorders post-stroke and brain injury may find it helpful to consider how the themes, drawn from an interview with the clinician in this study - flexibility, awareness of cultural context, person-centredness, being practical and working ethically - might apply to their practice. Narratives may be helpful in staff training and form an important

Peroxynitrite scavenging activity of herb extracts.

Peroxynitrite (ONOO(-)) is a cytotoxicant with strong oxidizing properties toward various cellular constituents, including sulphydryls, lipids, amino acids and nucleotides and can cause cell death, lipid peroxidation, carcinogenesis and aging. The aim of this study was to characterize ONOO(-) scavenging constituents from herbs. Twenty-eight herbs were screened for their ONOO(-) scavenging activities with the use of a fluorometric method. The potency of scavenging activity following the addition of authentic ONOO(-) was in the following order: witch hazel bark > rosemary > jasmine tea > sage > slippery elm > black walnut leaf > Queen Anne's lace > Linden flower. The extracts exhibited dose-dependent ONOO(-) scavenging activities. We found that witch hazel (Hamamelis virginiana L.) bark showed the strongest effect for scavenging ONOO(-) of the 28 herbs. Hamamelitannin, the major active component of witch hazel bark, was shown to have a strong ability to scavenge ONOO(-). It is suggested that hamamelitannin might be developed as an effective peroxynitrite scavenger for the prevention of ONOO(-) involved diseases. Copyright 2002 John Wiley & Sons, Ltd.

Severe Community-acquired Pneumonia Due to Legionella pneumophila Serogroup 6

Chung-Yu Chen

2006-01-01

Full Text Available Legionella pneumophila is a common cause of sporadic community-acquired pneumonia, but culture-proven legionellosis is rarely diagnosed. There is no laboratory test for Legionnaires' disease that can detect all patients with the disease. Culture is the standard diagnostic method and should be initiated as soon as possible in suspected cases. We describe a rare case of community-acquired pneumonia caused by L. pneumophila serogroup 6. A 77-year-old man was admitted to a tertiary care hospital because of high fever, productive cough, and progressive dyspnea. Chest radiography showed bilateral pneumonia, which led to respiratory failure necessitating mechanical ventilatory support. Despite antibiotic therapy, his condition continued to deteriorate and acute renal failure also developed. Urine was negative for L. pneumophila. Culture of the sputum yielded L. pneumophila serogroup 6, although there was no elevation of the serum antibody titer. Pneumonia resolved gradually and he was extubated after treatment with levofloxacin followed by erythromycin. L. pneumophila other than serogroup 1 should be included in the differential diagnosis of patients with suspected atypical community-acquired pneumonia.

The dynamics of naturally acquired immunity to Plasmodium falciparum infection.

Directory of Open Access Journals (Sweden)

Mykola Pinkevych

Full Text Available Severe malaria occurs predominantly in young children and immunity to clinical disease is associated with cumulative exposure in holoendemic settings. The relative contribution of immunity against various stages of the parasite life cycle that results in controlling infection and limiting disease is not well understood. Here we analyse the dynamics of Plasmodium falciparum malaria infection after treatment in a cohort of 197 healthy study participants of different ages in order to model naturally acquired immunity. We find that both delayed time-to-infection and reductions in asymptomatic parasitaemias in older age groups can be explained by immunity that reduces the growth of blood stage as opposed to liver stage parasites. We found that this mechanism would require at least two components - a rapidly acting strain-specific component, as well as a slowly acquired cross-reactive or general immunity to all strains. Analysis and modelling of malaria infection dynamics and naturally acquired immunity with age provides important insights into what mechanisms of immune control may be harnessed by malaria vaccine strategists.

The response of a recently acquired Canberra(trademark) Alpha Analyst 'Blue' system (Chamber Number's 173-208) used by the Hazards Control, Radiation Safety Section, WBC/Spectroscopy Team has been studied with respect to an existing Canberra system. The existing Canberra system consists of thirty Alpha Analyst dual chambers Model XXXX comprising a total of sixty detectors (Chambers Number's 101-124 and 137-172). The existing chambers were previously compared to an older system consisting of thirty-six Model 7401 alpha spectrometry chambers (Chamber Number's 1-36) Chambers 101-124 and 137-172 are DOELAP accredited. The older system was previously DOELAP accredited for the routine Alpha Spectroscopy program used in LLNL's in vitro bioassay program. The newly acquired Alpha Analyst system operates on a network with software that controls and performs analysis of the current Alpha Analyst system (Chamber Number's 101-124 and 137-172). This exact same software is used for the current system and the newly acquired system and is DOELAP accredited. This document compares results from the existing Alpha System with the newer Alpha Analyst system

It interferes with critical processes in the bacterial cell such as DNA replication, transcription, repair, and recombination by inhibiting bacterial topoisomerases. Levofloxacin has broad spectrum activity against several causative bacterial pathogens of community-acquired pneumonia (CAP. Oral levofloxacin is rapidly absorbed and is bioequivalent to the intravenous formulation such that patients can be conveniently transitioned between these formulations when moving from the inpatient to the outpatient setting. Furthermore, levofloxacin demonstrates excellent safety, and has good tissue penetration maintaining adequate concentrations at the site of infection. The efficacy and tolerability of levofloxacin 500 mg once daily for 10 days in patients with CAP are well established. Furthermore, a high-dose (750 mg and short-course (5 days of once-daily levofloxacin has been approved for use in the US in the treatment of CAP, acute bacterial sinusitis, acute pyelonephritis, and complicated urinary tract infections. The high-dose, short-course levofloxacin regimen maximizes its concentration-dependent antibacterial activity, decreases the potential for drug resistance, and has better patient compliance.Keywords: levofloxacin, community-acquired pneumonia, pharmacodynamics, resistance, pharmacokinetics, clinical use

Double-slit experiment in momentum space

Ivanov, I. P.; Seipt, D.; Surzhykov, A.; Fritzsche, S.

2016-08-01

Young's classic double-slit experiment demonstrates the reality of interference when waves and particles travel simultaneously along two different spatial paths. Here, we propose a double-slit experiment in momentum space, realized in the free-space elastic scattering of vortex electrons. We show that this process proceeds along two paths in momentum space, which are well localized and well separated from each other. For such vortex beams, the (plane-wave) amplitudes along the two paths acquire adjustable phase shifts and produce interference fringes in the final angular distribution. We argue that this experiment can be realized with the present-day technology. We show that it gives experimental access to the Coulomb phase, a quantity which plays an important role in all charged particle scattering but which usual scattering experiments are insensitive to.

Fear of acquired immunodeficiency syndrome and fear of other illness in suicide

DEFF Research Database (Denmark)

Aro, A R; Jallinoja, P T; Henriksson, M M

1994-01-01

Suicide victims with fear of acquired immunodeficiency syndrome (AIDS) or other somatic illness were compared for psychosocial and health-related characteristics, triggers and content of fear. Fear of AIDS cases (n = 28), 2% of the 1-year Finnish suicide population (n = 1397), were younger...... and fewer had serious somatic disease (32% vs 64%) compared with cases of fear of other somatic illness.

The impact of obesity on the outcome of pneumonia is uncertain. We retrospectively identified 266 hospitalized patients with proven pneumococcal or Haemophilus community-acquired pneumonia who had at least one body mass index (BMI, kg/m²) value documented in the 3 months before admission. Patients were classified as underweight (BMI values and BMI categories with the mortality at 30 days after admission for pneumonia was investigated. Increasing BMI values were associated with reduced 30-day mortality, even after adjustment for significant covariates (odds ratio 0.88, confidence interval 0.81-0.96; p<0.01). There was a significant trend towards lower mortality in the overweight and obese (non-parametric trend, p=0.02). Our data suggest that obesity may exert a protective effect against 30-day mortality from community-acquired bacterial pneumonia. Copyright © 2010 International Society for Infectious Diseases.

The sustained health-related quality-of-life of patients surviving community-acquired pneumonia has not been accurately quantified. The aim of the current study was to quantify differences in health-related quality-of-life of community-dwelling elderly with and without community-acquired pneumonia during a 12-month follow-up period. In a matched cohort study design, nested in a prospective randomized double-blind placebo-controlled trial on the efficacy of the 13-valent pneumococcal vaccine in community-dwelling persons of ≥65 years, health-related quality-of-life was assessed in 562 subjects hospitalized with suspected community-acquired pneumonia (i.e. diseased cohort) and 1145 unaffected persons (i.e. non-diseased cohort) matched to pneumonia cases on age, sex, and health status (EQ-5D-3L-index). Health-related quality-of-life was determined 1-2 weeks after hospital discharge/inclusion and 1, 6 and 12 months thereafter, using Euroqol EQ-5D-3L and Short Form-36 Health survey questionnaires. One-year quality-adjusted life years (QALY) were estimated for both diseased and non-diseased cohorts. Separate analyses were performed for pneumonia cases with and without radiologically confirmed community-acquired pneumonia. The one-year excess QALY loss attributed to community-acquired pneumonia was 0.13. Mortality in the post-discharge follow-up year was 8.4% in community-acquired pneumonia patients and 1.2% in non-diseased persons (p pneumonia patients, compared to non-diseased persons, but differences in health-related quality-of-life between radiologically confirmed and non-confirmed community-acquired pneumonia cases were not statistically significant. Community-acquired pneumonia was associated with a six-fold increased mortality and 16% lower quality-of-life in the post-discharge year among patients surviving hospitalization for community-acquired pneumonia, compared to non-diseased persons.

Stadler, Jacob A M; Andronikou, Savvas; Zar, Heather J

2017-10-01

Ultrasound (US) has been proposed as an alternative first-line imaging modality to diagnose community-acquired pneumonia in children. Lung US has the potential benefits over chest radiography of being radiation free, subject to fewer regulatory requirements, relatively lower cost and with immediate bedside availability of results. However, the uptake of lung US into clinical practice has been slow and it is not yet included in clinical guidelines for community-acquired pneumonia in children. The aim of this review is to give an overview of the equipment and techniques used to perform lung US in children with suspected pneumonia and the interpretation of relevant sonographic findings. We also summarise the current evidence of diagnostic accuracy and reliability of lung US compared to alternative imaging modalities in children and critically consider the strengths and limitations of lung US for use in children presenting with suspected community-acquired pneumonia.

Botulinum toxin in the management of sialorrhoea in acquired brain injury

Sialorrhoea as a consequence of severe acquired brain injury can significantly negatively impact on quality of life. Medications used in its management have many side effects which can cause problems in the severely disabled. Botulinum toxin is an effective treatment of sialorrhoea in a number of neurological conditions but may also have a role to play in the management of sialorrhoea following severe ABI. We report on 4 cases of sialorrhoea following acquired brain injury causing a variety of problems, whose parotid glands were injected with Botulinum toxin type A (Dysport) 50mu each, under ultrasound guidance. All cases had a clinically and statistically significant reduction in drooling as measured by the teacher drooling scale (p=0.005) and carers Visual Analogue Scale (p=0.012). There were no side effects reported. Botulinum toxin is an effective treatment for sialorrhoea associated with acquired brain injury.

This first comprehensive analysis of the global biogeography of marine protistan plankton with acquired phototrophy shows these mixotrophic organisms to be ubiquitous and abundant; however, their biogeography differs markedly between different functional groups. These mixotrophs, lacking a constitutive capacity for photosynthesis (i.e. non-constitutive mixotrophs, NCMs), acquire their phototrophic potential through either integration of prey-plastids or through endosymbiotic associations with photosynthetic microbes. Analysis of field data reveals that 40-60% of plankton traditionally labelled as (non-phototrophic) microzooplankton are actually NCMs, employing acquired phototrophy in addition to phagotrophy. Specialist NCMs acquire chloroplasts or endosymbionts from specific prey, while generalist NCMs obtain chloroplasts from a variety of prey. These contrasting functional types of NCMs exhibit distinct seasonal and spatial global distribution patterns. Mixotrophs reliant on 'stolen' chloroplasts, controlled by prey diversity and abundance, dominate in high-biomass areas. Mixotrophs harbouring intact symbionts are present in all waters and dominate particularly in oligotrophic open ocean systems. The contrasting temporal and spatial patterns of distribution of different mixotroph functional types across the oceanic provinces, as revealed in this study, challenges traditional interpretations of marine food web structures. Mixotrophs with acquired phototrophy (NCMs) warrant greater recognition in marine research. © 2017 The Author(s).

Hospital-acquired complications in a randomized controlled clinical trial of a geriatric consultation team.

Science.gov (United States)

Becker, P M; McVey, L J; Saltz, C C; Feussner, J R; Cohen, H J

1987-05-01

As part of a controlled clinical trial of a geriatric consultation team (GCT), we investigated whether a GCT could affect the incidence of hospital-acquired complications in elderly patients. One hundred eighty-five patients, aged 75 years and older, were randomized into an intervention (N = 92) and a control (N = 93) group. Members of the intervention group received a GCT consultation and were routinely followed up throughout their hospitalization. The incidence of hospital-acquired complications for the entire study population was 38%. The type and rate of hospital-acquired complications in the intervention and control groups were not significantly different. Functional status on admission and admission to the psychiatry service were predictive for the occurrence of a hospital-acquired complication. In a broadly selected population such as this, the intensity of care available through a GCT was unable to reduce the occurrence of hospital-acquired complications. However, since this is only one aspect of a GCT function, and others may be of great importance, such aspects, and more targeted populations, must be evaluated before final conclusions can be reached about GCT efficiency.

Mechanisms, Risk Factors, and Management of Acquired Long QT Syndrome: A Comprehensive Review

Directory of Open Access Journals (Sweden)

Eleftherios M. Kallergis

2012-01-01

Full Text Available Long QT syndrome is characterized by prolongation of the corrected QT (QTc interval on the surface electrocardiogram and is associated with precipitation of torsade de pointes (TdP, a polymorphic ventricular tachycardia that may cause sudden death. Acquired long QT syndrome describes pathologic excessive prolongation of the QT interval, upon exposure to an environmental stressor, with reversion back to normal following removal of the stressor. The most common environmental stressor in acquired long QT syndrome is drug therapy. Acquired long QT syndrome is an important issue for clinicians and a significant public health problem concerning the large number of drugs with this adverse effect with a potentially fatal outcome, the large number of patients exposed to these drugs, and our inability to predict the risk for a given individual. In this paper, we focus on mechanisms underlying QT prolongation, risk factors for torsades de pointes and describe the short- and long-term treatment of acquired long QT syndrome.

Acquired thrombotic thrombocytopenic purpura: new therapeutic options and their optimal use.

Science.gov (United States)

Cataland, S R; Wu, H M

2015-06-01

Advances in our understanding of the pathophysiology of both congenital and acquired thrombotic thrombocytopenic purpura (TTP) have led to both an increased understanding of the disease and novel approaches to therapy. The efficacy of rituximab in acquired TTP has led to consideration of rituximab as a prophylactic therapy to prevent relapse of TTP. Novel therapies that target the A1 domain of von Willebrand factor (VWF) to block the formation of microthrombotic disease have also entered clinical study and have demonstrated promise as potential therapeutic options. Additionally, a recombinant ADAMTS13 protease has been developed which may be an important therapeutic option for both congenital and acquired TTP. The development of these new therapeutic options for patients diagnosed with TTP has increased the importance of conducting prospective, randomized studies with these agents to both confirm their efficacy and more importantly understand their most appropriate role in the treatment of patients with TTP. © 2015 International Society on Thrombosis and Haemostasis.

Toward immunogenetic studies of amphibian chytridiomycosis: Linking innate and acquired immunity

Science.gov (United States)

Richmond, J.Q.; Savage, Anna E.; Zamudio, Kelly R.; Rosenblum, E.B.

2009-01-01

Recent declines in amphibian diversity and abundance have contributed significantly to the global loss of biodiversity. The fungal disease chytridiomycosis is widely considered to be a primary cause of these declines, yet the critical question of why amphibian species differ in susceptibility remains unanswered. Considerable evidence links environmental conditions and interspecific variability of the innate immune system to differential infection responses, but other sources of individual, population, or species-typical variation may also be important. In this article we review the preliminary evidence supporting a role for acquired immune defenses against chytridiomycosis, and advocate for targeted investigation of genes controlling acquired responses, as well as those that functionally bridge the innate and acquired immune systems. Immunogenetic data promise to answer key questions about chytridiomycosis susceptibility and host-pathogen coevolution, and will draw much needed attention to the importance of considering evolutionary processes in amphibian conservation management and practice. ?? 2009 by American Institute of Biological Sciences.

Clinical Predictors of Hospital-acquired Pneumonia Associated with Acute Ischemic

2015-06-01

Full Text Available Background: hospital-acquired pneumonia is a constant challenge given the current microbiological spectrum, antimicrobial resistance together with its high mortality, morbidity and hospital costs. Objective: to identify the clinical predictors of pneumonia associated with acute ischemic stroke. Methods: a prospective cohort study was conducted in 201 patients diagnosed with acute ischemic stroke consecutively admitted to the stroke unit of the General Carlos Manuel de Céspedes Teaching Hospital during the first seven days after the onset, from January 2012 through December 2013. The independent predictors of hospital-acquired pneumonia were obtained using multivariable logistic regression. Results: fifty six point seven percent were male. The mean age was 64.17 ± 14.33 years. Cases of hospital-acquired pneumonia associated with stroke accounted for 19, 9 %. Subjects who developed pneumonia were older (68.55 ± 13.51 vs. 63.08 ± 14.36 years, had a lower score in the Glasgow Coma Scale (8.00 ± 2.60 vs. 14.00 ± 2.82, and an increased number of leukocytes at admission (10.888 ± 3.487 vs. 9.233 ± 2.539 × 109/L. The following independent factors were identified: Glasgow Coma Scale ≤ 11 (OR: 26.099; 95 % CI 7.164-85.075, history of chronic obstructive pulmonary disease (OR: 8.896; 95 % CI 1.203-65.779, dysphagia (OR: 7.652; 95 % CI 2.369- 24.720, history of heart failure (OR: 4.583; 95 % CI 1.240- 16.932 and dysarthria/severe motor aphasia (OR: 4.222; 95 % CI 1.374- 12.975. Conclusions: the resulting logistic regression model is valid for predicting post-stroke pneumonia based on data routinely acquired.

2017-06-01

Neurological disorders in children highly affect the course of pneumonia, its outcome and the development of possible complications. The aim of the study was to reveal clinical and paraclinical features of community-acquired pneumonia in younger children with neurologic pathology infantile cerebral palsy. Under observation were 37 children with community-acquired pneumonia aged 1 to 3 years that suffered from spastic forms of infantile cerebral palsy. The comparison group consisted of 30 children with community-acquired pneumonia without any concomitant neurological pathology. The age of the children in the comparison and study groups was the same. The results of the study show that the presence of infantile cerebral palsy allow to relate the child to the risk group of respiratory pathology development. The course of community-acquired pneumonia in children affected by infantile cerebral palsy is characterized by rapid progression of symptoms and severity of the condition, and the clinical picture also has a number of characteristic features. Thus, cough, local physical data, classical laboratory signs of inflammation in the form of leukocytosis with neutrophil shift were noticed significantly less often in children with infantile cerebral palsy. The debut of the disease was often accompanied by bronchial obstruction, the inflammatory process was localized in the lower parts of the lungs and often matched the side of the neurologically affected part of the body. Children with cerebral palsy required a longer hospital-stay and a prolonged course of antibiotic therapy. Therefore, the risk of pneumonia in children with infantile cerebral palsy should be taken into account at the primary stage of medical care for the creation of preventive programs.

[Acquired drives. The cortical mechanism responsible to the emergence and development of social existence].

Science.gov (United States)

József, Knoll

2007-10-01

This paper is a brief interpretation of the theory (J. Knoll: The Brain and Its Self, Springer, 2005) the main message of which is that the appearance of the mammalian brain with the ability to acquire drives ensured the development of social life, and eventually led to the evolution of the human society. In the mammalian brain capable to acquire drives, untrained cortical neurons (Group 1) possess the potentiality to change their functional state in response to practice, training, or experience in three consecutive stages, namely, by getting involved in (a) an extinguishable conditioned reflex (ECR) (Group 2), (b) an inextinguishable conditioned reflex (ICR) (Group 3), or (c)an acquired drive (Group 4). The activity of the cortical neurons belonging to Group 3 and 4 is inseparable from conscious perception. In any moment of life self is the sum of those cortical neurons that have already changed their functional significance and belong to Group 3 or 4. Metaphorically, every human being is born with a telencephalon that resembles a book with over 100 billion empty pages (untrained, naive cortical neurons, Group 1), and with the capacity to inscribe as much as possible in this book throughout life. Whenever a drive is acquired, chains of ICRs are fixed, neurons responsible for emotions are also coupled to the integral whole, thus cognitive/volitional consciousness is necessarily inseparable from an affective state of consciousness. Cortical neurons belonging to Group 3 or 4 continuously synthesize their specific enhancer substance within their capacity. This means that even in the vigilant resting state (leisure), in the absence of a dominant drive, as well as in the non-vigilant resting state (sleeping), the cortical neurons representing the totality of the already fixed ICRs and acquired drives are permanently under the influence of their specific enhancer substance. Although the level of this permanent, undulating activation remains low, it is unpredictable as to

Rare acquired hemostatic disorders as a cause of prolonged bleeding – presentation of two case reports

Polona Novak

2011-10-01

Full Text Available BACKGROUNDPatient’s anamnesis is of primary importance in determining hemostatic disorders. Based on anamnestic data, a clinician may decide for further laboratory tests. We must consider an acquired bleeding disorder in a patient with unusual, unexpected and prolonged bleeding episodes. In this article we will describe two rare acquired hemostatic disordes.TWO CASE REPORTSOur first patient had prolonged bleeding after a pacemaker implantation. We diagnosed him with acquired von Willebrand syndrome. Further on, the patient required a planned surgical procedure. In our second case we describe a patient with unusual and excessive skin bruising and prolonged bleeding after teeth extractions. He was diagnosed with acquired hemophilia.CONCLUSIONIn the assessment of a patient with a potential acquired bleeding disorder we must first rule out the most common causes, such as iatrogenic ones. But, because of high morbidity and mortality rates, we must also be aware of some rare acquired bleeding disorders. In case of uncertainty, we should consult with a hematologist.

Label-acquired magnetorotation for biosensing: An asynchronous rotation assay

International Nuclear Information System (INIS)

Hecht, Ariel; Kinnunen, Paivo; McNaughton, Brandon; Kopelman, Raoul

2011-01-01

This paper presents a novel application of magnetic particles for biosensing, called label-acquired magnetorotation (LAM). This method is based on a combination of the traditional sandwich assay format with the asynchronous magnetic bead rotation (AMBR) method. In label-acquired magnetorotation, an analyte facilitates the binding of a magnetic label bead to a nonmagnetic solid phase sphere, forming a sandwich complex. The sandwich complex is then placed in a rotating magnetic field, where the rotational frequency of the sandwich complex is a function of the amount of analyte attached to the surface of the sphere. Here, we use streptavidin-coated beads and biotin-coated particles as analyte mimics, to be replaced by proteins and other biological targets in future work. We show this sensing method to have a dynamic range of two orders of magnitude.

Ahmad, M. K.; Asrar, A.

2014-01-01

Objective: To determine the percentage and frequency of Methicillin Resistant Staphylococcus aureus in community and hospital-acquired pyogenic skin and soft tissue infections. Methods: The descriptive cross-sectional study was conducted at the Dermatology Department of Combined Military Hospital, Abbottabad, from June 2009 to March 2010, and comprised 144 community-acquired and 54 hospital-acquired skin and soft tissue infections. Pus swabs from the infected lesions one from each individual were sent to laboratory for culture and sensitivity tests. Methicillin resistance was detected by 1 (mu) g oxacillin disk. Organisms were labelled methicillin-resistant once the inhibition zone for oxocillin was less than 10 mm. Data analysis was done by using SPSS 20. Results: Of the 198 patients in the study, 98(49.5%) were males and 100(50.5%) were females, with an overall mean age of 33.7+-14.8144 years. There were 144(72.72%) community-acquired infections and 54(27.27%) had hospital-acquired infections. Community-acquired Methicillin Resistant Staphylococcus aureus numbered 40(27.8%) and hospital-acquired ones numbered 26(48.1%). Conclusion: Prevalence of Methicillin Resistant Staphylococcus aureus in community and hospital-acquired pyogenic skin and soft tissue infections was high. (author)

How to acquire customers on the Web.

Science.gov (United States)

Hoffman, D L; Novak, T P

2000-01-01

Most retailers on the Web spend more to acquire customers than they will ever get back in revenue from them. Many think that sky-high spending on marketing is necessary to stake out their share of Internet space. But is it really? How do retailers know how much to pay? Consider CDnow, which has developed a multifaceted customer-acquisition strategy that reflects a clear understanding of the economics of an on-line business. At the heart of its strategy is affiliate marketing, a concept the company pioneered. Under its BuyWeb program, anyone can put a link to CDnow on his or her Web site, and if a customer uses that link to arrive at CDnow and make a purchase, the referring site owner gets a percentage of the sale. CDnow pays no money if no sale is made, which makes the marketing program completely efficient. But CDnow didn't stop there. Being a Web store, it had complete data on the number of visitors to its site and what they bought, which it used to work out the lifetime value of an average customer. CDnow used that figure to determine how much to wager on the expensive and risky world of traditional advertising to reach a wider audience that wasn't already on-line. CDnow's experience, still a work in progress, contradicts John Wanamaker's oft-quoted lament: "I know half the money I spend on advertising is wasted, but I can never find out which half." As the CDnow example demonstrates, there is a way to find out which half really works.

Homophily and the speed of social mobilization: the effect of acquired and ascribed traits.

Alstott, Jeff; Madnick, Stuart; Velu, Chander

2014-01-01

Large-scale mobilization of individuals across social networks is becoming increasingly prevalent in society. However, little is known about what affects the speed of social mobilization. Here we use a framed field experiment to identify and measure properties of individuals and their relationships that predict mobilization speed. We ran a global social mobilization contest and recorded personal traits of the participants and those they recruited. We studied the effects of ascribed traits (gender, age) and acquired traits (geography, and information source) on the speed of mobilization. We found that homophily, a preference for interacting with other individuals with similar traits, had a mixed role in social mobilization. Homophily was present for acquired traits, in which mobilization speed was faster when the recuiter and recruit had the same trait compared to different traits. In contrast, we did not find support for homophily for the ascribed traits. Instead, those traits had other, non-homophily effects: Females mobilized other females faster than males mobilized other males. Younger recruiters mobilized others faster, and older recruits mobilized slower. Recruits also mobilized faster when they first heard about the contest directly from the contest organization, and decreased in speed when hearing from less personal source types (e.g. family vs. media). These findings show that social mobilization includes dynamics that are unlike other, more passive forms of social activity propagation. These findings suggest relevant factors for engineering social mobilization tasks for increased speed.

Younger recruiters mobilized others faster, and older recruits mobilized slower. Recruits also mobilized faster when they first heard about the contest directly from the contest organization, and decreased in speed when hearing from less personal source types (e.g. family vs. media. These findings show that social mobilization includes dynamics that are unlike other, more passive forms of social activity propagation. These findings suggest relevant factors for engineering social mobilization tasks for increased speed.

Tacit knowledge of health-care experts is an important source of experiential know-how, yet due to various operational and technical reasons, such health-care knowledge is not entirely harnessed and put into professional practice. Emerging knowledge-management (KM) solutions suggest strategies to acquire the seemingly intractable and nonarticulated tacit knowledge of health-care experts. This paper presents a KM methodology, together with its computational implementation, to 1) acquire the tacit knowledge possessed by health-care experts; 2) represent the acquired tacit health-care knowledge in a computational formalism--i.e., clinical scenarios--that allows the reuse of stored knowledge to acquire tacit knowledge; and 3) crystallize the acquired tacit knowledge so that it is validated for health-care decision-support and medical education systems.

We assess the retention of robot-assisted surgical skills among urologic surgeons. The robot-assisted surgery skills of 20 urologic surgeons were assessed using a Mimic dV-Trainer program (Mimic Technologies, Inc., Seattle, WA) consisting of 6 tasks. These 20 surgeons had no previous experience either using the Mimic dV-Trainer or acting as the main surgeon in robot-assisted surgery. The surgeons completed the program 4 times in a row; after 1 year, they completed it again for a fifth time. Performance scores were recorded using the Mimic dV-Trainer's built-in algorithm. For all 6 tasks, there were significant improvements to the scores in the fourth trials compared with those in the first trials. The scores in the fifth trials did not significantly decline compared with those in the fourth trials. There was no significant difference between the fifth trial scores of surgeons with laparoscopic surgery skills/experience and those without. Our results indicate that fundamental robot-assisted surgical skills can be retained in the long-term after they are acquired.

Ways and intensity of trans-nationalization process of Western oil companies have dramatically changed over the last thirty years. After a decline from 1970 to 1984, a new era of investment extraversion from home base is developing. We discuss then the extent to witch this new era is a part of a larger process of firms globalization interacting witch political internationalization. The existence of a clear globalization trend is recognized inside the oil industry, but with a persisting specificity coming from the access conditions to the oil deposits. (author)

Life goals and social identity in people with severe acquired brain injury: an interpretative phenomenological analysis.

Martin, Rachelle; Levack, William M M; Sinnott, K Anne

2015-01-01

While there is a growing body of literature exploring life goals in rehabilitation, little research has been undertaken that includes the voice of the end-user. This study examined the views and experiences of people with severe acquired brain injury regarding the place of "life goals" in residential rehabilitation. Interpretative phenomenological analysis was used to collect and analyze data from five semi-structured interviews with participants in a residential rehabilitation setting. Three inter-related themes emerged from this study. Social connectedness (being 'part of things') emerged as a life goal of central importance for all participants (Theme 1). However, in order to achieve this sense of belonging, the participants needed to tentatively balance the opportunities arising within their environmental milieu (Theme 2) with the interpersonal factors relating to their unchanged, changed and changing self-identity (Theme 3). This study suggests that social identity and social connectedness ought to be primary foci of rehabilitation rather than matters only of secondary concern. Consideration needs to be given to both the environmental contexts and the intrapersonal strategies that support people who require residential rehabilitation services to achieve social connection, and thus their life goals, following a severe acquired brain injury. Implications for Rehabilitation There is a need to better support people with severe acquired brain injury (ABI) in terms of their social relationships and social identity during the delivery of person-centered rehabilitation services. Within the clinical setting there should be regular, in depth and open dialogue in which the individuals' values and preferences are discovered. A focus on the coherence between daily activities and the person's life goals is required for people with severe ABI. Clinicians need to consider how life goals for individual people change or are re-prioritized over the life span.

2016-10-01

This study explored speech-language pathologists' (SLPs) perspectives about factors that influence clinical management of Aboriginal and Torres Strait Islander adults with acquired communication disorders (e.g. aphasia, motor speech disorders). Using a qualitative phenomenological approach, seven SLPs working in North Queensland, Australia with experience working with this population participated in semi-structured in-depth interviews. Qualitative content analysis was used to identify categories and overarching themes within the data. Four categories, in relation to barriers and facilitators, were identified from participants' responses: (1) The Practice Context; (2) Working Together; (3) Client Factors; and (4) Speech-Language Pathologist Factors. Three overarching themes were also found to influence effective speech pathology services: (1) Aboriginal and Torres Strait Islander Cultural Practices; (2) Information and Communication; and (3) Time. This study identified many complex and inter-related factors which influenced SLPs' effective clinical management of this caseload. The findings suggest that SLPs should employ a flexible, holistic and collaborative approach in order to facilitate effective clinical management with Aboriginal and Torres Strait Islander people with acquired communication disorders.

Bo Zhao; Haldar, Justin P; Setsompop, Kawin; Wald, Lawrence L

2016-08-01

Magnetic resonance (MR) fingerprinting is an emerging quantitative MR imaging technique that simultaneously acquires multiple tissue parameters in an efficient experiment. In this work, we present an estimation-theoretic framework to evaluate and design MR fingerprinting experiments. More specifically, we derive the Cramér-Rao bound (CRB), a lower bound on the covariance of any unbiased estimator, to characterize parameter estimation for MR fingerprinting. We then formulate an optimal experiment design problem based on the CRB to choose a set of acquisition parameters (e.g., flip angles and/or repetition times) that maximizes the signal-to-noise ratio efficiency of the resulting experiment. The utility of the proposed approach is validated by numerical studies. Representative results demonstrate that the optimized experiments allow for substantial reduction in the length of an MR fingerprinting acquisition, and substantial improvement in parameter estimation performance.

Ketogenic diet therapies have proven efficacy for refractory epilepsy. There are many reports of their use in the genetic developmental and epileptic encephalopathies; however, little attention has been paid as to whether the diet is also effective in individuals with an acquired structural aetiology. We observed remarkable efficacy of the diet in two patients with hypoxic-ischaemic encephalopathy. We then analysed our cases with refractory structural epilepsies of acquired origin to characterize their response to the ketogenic diet. The classical ketogenic diet was implemented with dietary ratios of 3:1 to 4.4:1. Seizure frequency at 1 month, 3 months, 6 months, 1 year, and 2 years was ascertained. A responder was defined as greater than 50% seizure reduction compared to baseline. Seven of the nine patients were responders at 3 months. Somewhat surprisingly we found that the ketogenic diet was effective in patients with a developmental and epileptic encephalopathy due to an acquired structural aetiology. This cohort may not be routinely considered for the ketogenic diet because of their structural and acquired, rather than genetic, basis. The ketogenic diet should be considered early in the management of patients with acquired structural encephalopathies as it can improve seizure control with the potential to improve developmental outcome. The ketogenic diet was effective in children with epilepsy associated with an acquired structural aetiology. © 2018 Mac Keith Press.

Acquired hyperostosis syndrome. Pt. 2

In the second part of this publication, we describe some additional findings in cases of sternocostoclavicular hyperostosis (SCCH). These include focal hyperostosis of the spine, in the pelvis and in the extremities and psoriatric skin lesions and severe forms of acne (acne conglobata, acne fulminans). An analysis of our 13 patients and of the relevant literature indicates that the hyperostosis is due to increased bone metabolism and heterotopic ossification of fibrous tissue and that these are the pathogenic bases of the changes in the axial skeleton, the pelvis and the bones of the extremities. We have suggested a scheme which would categorise the syndrom into complete, incomplete and possibly acquired forms. (orig./GDG).

Community-acquired pneumonia

Poetter-Lang, S.; Herold, C.J.

2017-01-01

The diagnosis of community-acquired pneumonia (CAP) is often not possible based only on the clinical symptoms and biochemical parameters. For every patient with the suspicion of CAP, a chest radiograph in two planes should be carried out. Additionally, a risk stratification for the decision between outpatient therapy or hospitalization is recommended. Based on the evaluation of the different radiological patterns as well as their extent and distribution, a rough allocation to so-called pathogen groups as well as a differentiation between viral and bacterial infections are possible; however, because different pathogens cause different patterns an accurate correlation is not feasible by relying purely on imaging. The radiological findings serve as proof or exclusion of pneumonia and can also be used to evaluate the extent of the disease (e.g. monolobular, multilobular, unilateral or bilateral). In cases of prolonged disease, suspicion of complications (e.g. pleural effusion or empyema, necrotizing pneumonia or abscess) or comorbid conditions (e.g. underlying pulmonary or mediastinal diseases) computed tomography is an important diagnostic tool in addition to chest radiography. Ultrasound is often used to diagnose pleural processes (e.g. parapneumonic effusion or pleural empyema). (orig.) [de

Acquired hemophilia A is a rare bleeding disorder caused by autoantibodies to coagulation factor VIII (FVIII). In most cases, bleeding episodes are spontaneous and severe at presentation. The optimal hemostatic therapy is controversial. To determine the efficacy of hemostatic therapies for acute bleeds in people with acquired hemophilia A; and to compare different forms of therapy for these bleeds. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 4) and MEDLINE (Ovid) (1948 to 30 April 2014). We searched the conference proceedings of the: American Society of Hematology; European Hematology Association; International Society on Thrombosis and Haemostasis (ISTH); and the European Association for Haemophilia and Allied Disorders (EAHAD) (from 2000 to 30 April 2014). In addition to this we searched clinical trials registers. All randomised controlled trials and quasi-randomised trials of hemostatic therapies for people with acquired hemophilia A, with no restrictions on gender, age or ethnicity. No trials matching the selection criteria were eligible for inclusion. No trials matching the selection criteria were eligible for inclusion. No randomised clinical trials of hemostatic therapies for acquired hemophilia A were found. Thus, we are not able to draw any conclusions or make any recommendations on the optimal hemostatic therapies for acquired hemophilia A based on the highest quality of evidence. GIven that carrying out randomized controlled trials in this field is a complex task, the authors suggest that, while planning randomised controlled trials in which patients can be enrolled, clinicians treating the disease continue to base their choices on alternative, lower quality sources of evidence, which hopefully, in the future, will also be appraised and incorporated in a Cochrane Review.

Acquired hemophilia A (AHA) is a rare autoimmune disease caused by autoantibodies against coagulation factor VIII and characterized by spontaneous hemorrhage in patients with no previous family or personal history of bleeding. Although data on several AHA cohorts have been collected, limited information is available on the optimal management of AHA. The European Acquired Hemophilia Registry (EACH2) was established to generate a prospective, large-scale, pan-European database on demographics, diagnosis, underlying disorders, bleeding characteristics, treatment and outcome of AHA patients. Five hundred and one (266 male, 235 female) patients from 117 centers and 13 European countries were included in the registry between 2003 and 2008. In 467 cases, hemostasis investigations and AHA diagnosis were triggered by a bleeding event. At diagnosis, patients were a median of 73.9 years. AHA was idiopathic in 51.9%; malignancy or autoimmune diseases were associated with 11.8% and 11.6% of cases. Fifty-seven per cent of the non-pregnancy-related cases were male. Four hundred and seventy-four bleeding episodes were reported at presentation, and hemostatic therapy initiated in 70.5% of patients. Delayed diagnosis significantly impacted treatment initiation in 33.5%. Four hundred and seventy-seven patients underwent immunosuppression, and 72.6% achieved complete remission. Representing the largest collection of consecutive AHA cases to date, EACH2 facilitates the analysis of a variety of open questions in AHA. © 2012 International Society on Thrombosis and Haemostasis.

The credibility of prognostic indicators in nursing-home-acquired pneumonia (NHAP) is not clear. We previously reported a simple prognostic indicator in community-acquired pneumonia (CAP): blood urea nitrogen to serum albumin (B/A) ratio. This retrospective study investigated the prognostic value of severity indicators in NHAP versus CAP in elderly patients. Patients aged ≥65 years and hospitalized because of NHAP or CAP within the previous 3 years were enrolled. Demographics, coexisting illnesses, laboratory and microbiological findings, and severity scores (confusion, urea, respiratory rate, blood pressure, and age ≥65 [CURB-65] scale; age, dehydration, respiratory failure, orientation disturbance, and pressure [A-DROP] scale; and pneumonia severity index [PSI]) were retrieved from medical records. The primary outcome was mortality within 28 days of admission. In total, 138 NHAP and 307 CAP patients were enrolled. Mortality was higher in NHAP (18.1%) than in CAP (4.6%) (Pscale, 0.69 for the CURB-65 scale, 0.67 for the PSI class, and 0.65 for the B/A ratio. The area under the curve in CAP was 0.73 for the A-DROP scale, 0.76 for the CURB-65 scale, 0.81 for the PSI class, and 0.83 for the B/A ratio. Patient mortality was greater in NHAP than in CAP. Patient characteristics, coexisting illnesses, and detected pathogens differed greatly between NHAP and CAP. The existing severity indicators had less prognostic value for NHAP than for CAP.

The Interpersonal Psychological Theory of suicide proposes that the interaction between Thwarted Belongingness, Perceived Burdensomeness, and Acquired Capability for Suicide (ACS) predicts proximal risk of death by suicide. Instruments to assess all three constructs are available. However, research on the validity of one of them, the acquired capability for suicide scale (ACSS), has been limited, especially in terms of its clinical relevance. This study aimed to explore the utility of the different versions of the ACSS in clinical assessment. Three versions of the scale were investigated, the full 20-item version, a 7-item version and a single item version representing self-perceived capability for suicide. In a sample of patients recruited from a clinic specialising in the treatment of suicidality and in a community sample, all versions of the ACSS were found to show reasonable levels of reliability and to correlate as expected with reports of suicidal ideation, self-harm, and attempted suicide. The item assessing self-perceived acquired capacity for suicide showed highest correlations with all levels of suicidal behaviour. However, no version of the ACSS on its own showed a capacity to indicate suicide attempts in the combined sample. It is concluded that the versions of the scale have construct validity, but their clinical utility is limited. An assessment using a single item on self-perceived ACS outperforms the full and shortened versions of ACSS in clinical settings and can be recommended with caution for clinicians interested in assessing this characteristic.

Acquired hemophilia A (AHA) is a rare bleeding disorder characterized by autoantibodies directed against circulating coagulation factor (F) VIII. Typically, patients with no prior history of a bleeding disorder present with spontaneous bleeding and an isolated prolonged aPTT. AHA may, however, present without any bleeding symptoms, therefore an isolated prolonged aPTT should always be investigated further irrespective of the clinical findings. Control of acute bleeding is the first priority, and we recommend first-line therapy with bypassing agents such as recombinant activated FVII or activated prothrombin complex concentrate. Once the diagnosis has been achieved, immediate autoantibody eradication to reduce subsequent bleeding risk should be performed. We recommend initial treatment with corticosteroids or combination therapy with corticosteroids and cyclophosphamide and suggest second-line therapy with rituximab if first-line therapy fails or is contraindicated. In contrast to congenital hemophilia, no comparative studies exist to support treatment recommendations for patients with AHA, therefore treatment guidance must rely on the expertise and clinical experience of specialists in the field. The aim of this document is to provide a set of international practice guidelines based on our collective clinical experience in treating patients with AHA and contribute to improved care for this patient group.

Espinoza, J Luis; Kotecha, Ritesh; Nakao, Shinji

2017-01-01

Acquired bone marrow failure syndromes encompass a unique set of disorders characterized by a reduction in the effective production of mature cells by the bone marrow (BM). In the majority of cases, these syndromes are the result of the immune-mediated destruction of hematopoietic stem cells or their progenitors at various stages of differentiation. Microbial infection has also been associated with hematopoietic stem cell injury and may lead to associated transient or persistent BM failure, and recent evidence has highlighted the potential impact of commensal microbes and their metabolites on hematopoiesis. We summarize the interactions between microorganisms and the host immune system and emphasize how they may impact the development of acquired BM failure.

2008-04-15

4 dogs with acquired pulmonary artery stenosis (PAS) were examined for various clinical signs. One was a mixed-breed dog with congenital valvular PAS that subsequently developed peripheral PAS, one was a Golden Retriever with pulmonary valve fibrosarcoma, one was a Pembroke Welsh Corgi in which the left pulmonary artery had inadvertently been ligated during surgery for correction of patent ductus arteriosus, and one was a Boston Terrier with a heart-base mass compressing the pulmonary arteries. All 4 dogs were evaluated with 2-dimensional and Doppler echocardiography to characterize the nature and severity of the stenoses; other diagnostic tests were also performed. The mixed-breed dog with valvular and peripheral PAS was euthanized, surgical resection of the pulmonic valve mass was performed in the Golden Retriever, corrective surgery was performed on the Pembroke Welsh Corgi with left pulmonary artery ligation, and the Boston Terrier with the heart-base mass was managed medically. Acquired PAS in dogs may manifest as a clinically silent heart murmur, syncope, or right-sided heart failure. The diagnosis is made on the basis of imaging findings, particularly results of 2-dimensional and Doppler echocardiography. Treatment may include surgical, interventional, or medical modalities and is targeted at resolving the inciting cause.

Software for Acquiring Image Data for PIV

Wernet, Mark P.; Cheung, H. M.; Kressler, Brian

2003-01-01

PIV Acquisition (PIVACQ) is a computer program for acquisition of data for particle-image velocimetry (PIV). In the PIV system for which PIVACQ was developed, small particles entrained in a flow are illuminated with a sheet of light from a pulsed laser. The illuminated region is monitored by a charge-coupled-device camera that operates in conjunction with a data-acquisition system that includes a frame grabber and a counter-timer board, both installed in a single computer. The camera operates in "frame-straddle" mode where a pair of images can be obtained closely spaced in time (on the order of microseconds). The frame grabber acquires image data from the camera and stores the data in the computer memory. The counter/timer board triggers the camera and synchronizes the pulsing of the laser with acquisition of data from the camera. PIVPROC coordinates all of these functions and provides a graphical user interface, through which the user can control the PIV data-acquisition system. PIVACQ enables the user to acquire a sequence of single-exposure images, display the images, process the images, and then save the images to the computer hard drive. PIVACQ works in conjunction with the PIVPROC program which processes the images of particles into the velocity field in the illuminated plane.

2005-02-01

Patients with Dissociative Identity Disorder (DID) frequently report episodes of interidentity amnesia, that is amnesia for events experienced by other identities. The goal of the present experiment was to test the implicit transfer of trauma-related information between identities in DID. We hypothesized that whereas declarative information may transfer from one identity to another, the emotional connotation of the memory may be dissociated, especially in the case of negative, trauma-related emotional valence. An evaluative conditioning procedure was combined with an affective priming procedure, both performed by different identities. In the evaluative conditioning procedure, previously neutral stimuli come to refer to a negative or positive connotation. The affective priming procedure was used to test the transfer of this acquired valence to an identity reporting interidentity amnesia. Results indicated activation of stimulus valence in the affective priming task, that is transfer of emotional material between identities.

Full Text Available Aim of the study — to examine the effectiveness of sequential therapy of injectable and oral forms cephalosporins of II generation, cefuroxime sodium and cefprozil, in children with acute community-acquired pneumonia. We examined 53 child patients aged 6 months — 14 years with acute community-acquired pneumonia. Patients were divided into 2 groups: 1st group — 26 patients who treated with cefuroxime sodium intramuscularly, and 2nd — 27 patients who treated with cefuroxime sodium in first 3 days and then from the 4th day — with cefprozil suspension orally. Both groups of patients were comparable by forms and course of pneumonia. In the clinic to all patients were conducted conventional clinical and laboratory investigations. Complex therapy was not different in both groups. Efficacy of treatment was assessed in dynamics. When comparing the effectiveness of two antibiotic regimens (cefuroxime sodium parenterally and sequential regimen with replacement by cefprozil orally there were no differences in the dynamics of clinical course, laboratory and radiological data. Finding of the conducted investigations before treatment showed that majority of patients had clinical and radiological evidence of pneumonia: fever, cough, shortness of breath, tachycardia, physical and radiological changes in the lungs. Evaluation of treatment efficacy showed that by the end of treatment in both groups of patients there was a positive clinical and radiological dynamics of the disease, the body temperature returned to normal, symptoms of intoxication, physical changes in the lungs disappeared, focal and infiltrative changes disappeared completely. Thus, sequential therapy with cephalosporins of II generation, cefuroxime and cefprozil, in the treatment of acute community-acquired pneumonia in children is a quite effective and safe method with good tolerability and no side effects.

The properties of two highly radioresistant bacterial strains namely B. laterosporous and B. firmus isolated, three years ago, from the water shielding the industrial Co-60 source of NCRRT Egypt were studied. The results showed that the studied isolates had lost their resistance to gamma irradiation as compared with their properties acquired at the time of isolation. The sensitivity test of these isolates to some antibiotics and sulpha drugs was also investigated, and was compared with tests performed on the same species isolated from tap water. The pronounced resistance of these isolates to some antibiotics acquired three years ago, had been lost by storage except for the case of the drug chemotrim. The results indicated that the acquired resistivity to both gamma irradiation and antibiotics due to the chronic exposure to gamma radiation is not stable. It is concluded that the genes controlling both phenomena, in the studied strains, fall into broad categories and the case might be a repair mechanism in the DNA during successive reproduction.2 fig., 2 tab

Sepsis can be complicated by secondary infections. We explored the possibility that patients with sepsis developing a secondary infection while in the intensive care unit (ICU) display sustained inflammatory, vascular, and procoagulant responses. To compare systemic proinflammatory host responses in patients with sepsis who acquire a new infection with those who do not. Consecutive patients with sepsis with a length of ICU stay greater than 48 hours were prospectively analyzed for the development of ICU-acquired infections. Twenty host response biomarkers reflective of key pathways implicated in sepsis pathogenesis were measured during the first 4 days after ICU admission and at the day of an ICU-acquired infection or noninfectious complication. Of 1,237 admissions for sepsis (1,089 patients), 178 (14.4%) admissions were complicated by ICU-acquired infections (at Day 10 [6-13], median with interquartile range). Patients who developed a secondary infection showed higher disease severity scores and higher mortality up to 1 year than those who did not. Analyses of biomarkers in patients who later went on to develop secondary infections revealed a more dysregulated host response during the first 4 days after admission, as reflected by enhanced inflammation, stronger endothelial cell activation, a more disturbed vascular integrity, and evidence for enhanced coagulation activation. Host response reactions were similar at the time of ICU-acquired infectious or noninfectious complications. Patients with sepsis who developed an ICU-acquired infection showed a more dysregulated proinflammatory and vascular host response during the first 4 days of ICU admission than those who did not develop a secondary infection.

Cosmic ray runs acquired with ATLAS muon stations

CERN Multimedia

Cerutti, F.

Starting in the fall 2005 several cosmic ray runs have been acquired in the ATLAS pit with six muon stations. These were three large outer and three large middle chambers of the feet sector (sector 13) that have been readout in the ATLAS cavern. In the first data taking period the trigger was based on two large scintillators (~300x30 cm2) positioned in sector 13 just below the large chambers. In this first run the precision chambers (the Monitored Drift Tubes) were operated in a close to final configuration. Typical trigger rates with this setup were of the order of 1 Hz. Several data sets of 10k events were acquired with final electronics up to the muon ROD and analysed with ATHENA-based software. These data allowed the first checks of the functionality and efficiency of the MDT stations in the ATLAS pit and the first measurement of the FE electronics noise in the ATLAS environment. A few event were also collected in a combined run with the TILE barrel calorimeter. An event display of a cosmic ray a...

Bae, Sung-Heui

This integrative review synthesized evidence on the consequences of the Centers for Medicare & Medicaid Services (CMS) nonpayment policy on quality improvement initiatives and hospital-acquired conditions. Fourteen articles were included. This review presents strong evidence that the CMS policy has spurred quality improvement initiatives; however, the relationships between the CMS policy and hospital-acquired conditions are inconclusive. In future research, a comprehensive model of implementation of the CMS nonpayment policy would help us understand the effectiveness of this policy.

This paper is a new step in the search of minimum dynamic parameters of robots. In spite of planing exciting trajectories and using base parameters, some parameters remain not identifiable due to the perturbation effects. In this paper, we propose methods to reduce the set of base parameters in order to get an essential set of parameters. This new set defines a simplified identification model witch improves the noise immunity of the estimation process. It contributes also in reducing the computation burden of a simplified dynamic model. Different methods are proposed and are classified in two parts: methods, witch perform reduction and identification together, come from statistical field and methods, witch reduces the model before the identification thanks to a priori information, come from numerical field like the QR factorization. Statistical tools and QR reduction are shown to be efficient and adapted to determine the essential parameters. They can be applied to open-loop, or graph structured rigid robot, as well as flexible-link robot. Application for the PUMA 560 robot is given. (authors). 9 refs., 4 tabs

The Acquired Capability for Lethal Self Injury: Case Studies of Plath’s The Bell Jar and Eugenides’ The Virgin Suicides

2017-07-01

Full Text Available Interpersonal theory developed by Joiner (2005 is based on the assumption that people die by suicide because they can-acquired capability-and because they want to- desire of suicide.  Desire to die arises from two specific psychological states: perceived burdensomeness and thwarted belongingness.  The obtained ability of committing suicidal thoughts referred to the second segment of the approach consists of some specific factors, i.e., the person must be capable of doing some lethal activities courageously to put an end to the life; therefore, they present a fearless attitude towards death.  Another factor is endurance to face self-injuries pain acquired from the long painful experiences or probably stimulating and motivating situations.  In this paper, the researchers intended to present a Joinerian reading of Sylvia Plath’s only novel, the Bell Jar, and one of Jeffrey Eugenides’ prominent works, the Virgin Suicides.  In fact, this qualitative study would analyze the two selected novels (i.e., the Bell Jar and the Virgin Suicides by the use of the acquired capability for suicide to find out why one takes his/her life by his/her own hands.  Based on the findings, Loneliness, social isolation, and thwarted effectiveness can be the mental states that have inflicted an acute pain on the heroines, a pain that makes them ready to die by suicides.  Suicidal ideation and witnessing other’s suicidal behaviors, habituates the heroines to the concept of death and suicide.

Knowledge transfer process of Brazilian multinationals: comparing acquired subsidiaries to the greenfield ones

Natacha Bertoia Silva

2012-07-01

Full Text Available The main purpose of this study was to explore the knowledge transfer process between the subsidiaries and the headquarter of Brazilian multinationals, and to identify the most used mechanisms for transferring knowledge. This paper also aims to point out existing barriers in this process, comparing acquired subsidiaries to the greenfield ones. International studies have shown differences in the process of knowledge transfer due to the origin of foreign units (entry mode. We surveyed in 2006 and 2007 a sample of 66 Brazilian subsidiaries of multinationals with overseas activities. As a result, the knowledge transfer from the headquarter to the subsidiary has occurred through meetings with top executives and the reception of Brazilian executives in both types of units. The barriers to knowledge transfer are bland, being clearer in acquired subsidiaries. Cultural resistance is the most prominent. When we focus on the acquired units, the hierarchical structure is seen as a barrier, probably reflecting the centralized attitude by the headquarters. At the same time, the lack of incentives for sharing knowledge is more evident in greenfield units. Also, the syndrome of not invented here is a perceived barrier by acquired units.

The role of acquired immunity and periodontal disease progression.

Science.gov (United States)

Teng, Yen-Tung A

2003-01-01

Our understanding of the pathogenesis in human periodontal diseases is limited by the lack of specific and sensitive tools or models to study the complex microbial challenges and their interactions with the host's immune system. Recent advances in cellular and molecular biology research have demonstrated the importance of the acquired immune system not only in fighting the virulent periodontal pathogens but also in protecting the host from developing further devastating conditions in periodontal infections. The use of genetic knockout and immunodeficient mouse strains has shown that the acquired immune response-in particular, CD4+ T-cells-plays a pivotal role in controlling the ongoing infection, the immune/inflammatory responses, and the subsequent host's tissue destruction. In particular, studies of the pathogen-specific CD4+ T-cell-mediated immunity have clarified the roles of: (i) the relative diverse immune repertoire involved in periodontal pathogenesis, (ii) the contribution of pathogen-associated Th1-Th2 cytokine expressions in periodontal disease progression, and (iii) micro-organism-triggered periodontal CD4+ T-cell-mediated osteoclastogenic factor, 'RANK-L', which is linked to the induction of alveolar bone destruction in situ. The present review will focus on some recent advances in the acquired immune responses involving B-cells, CD8+ T-cells, and CD4+ T-cells in the context of periodontal disease progression. New approaches will further facilitate our understanding of their underlying molecular mechanisms that may lead to the development of new treatment modalities for periodontal diseases and their associated complications.

Shigellosis is a leading cause of enteric infections in the United States. We compared antimicrobial resistance in Shigella infections related to overseas travel (travel-associated) and in those acquired domestically by analyzing antimicrobial resistance patterns, geographic distributions, and pulsed-field gel electrophoresis (PFGE) patterns. We tested samples (n = 204) from a collection of isolates recovered from patients in Pennsylvania between 2006 and 2014. Isolates were grouped into travel- and non-travel-associated categories. Eighty-one (79.4%) of the Shigella isolates acquired during international travel were resistant to multiple antibiotics compared to 53 (52.1%) of the infections transmitted in domestic settings. A majority (79.4%) of isolates associated with international travel demonstrated resistance to aminoglycosides and tetracyclines, whereas 47 (46.1%) of the infections acquired domestically were resistant to tetracycline. Almost all isolates (92.2%) transmitted in domestic settings were resistant to aminoglycosides, and 5 isolates from adult male patients were resistant to azithromycin, a drug often used for empiric treatment of severe shigellosis. Twenty (19.6%) isolates associated with illnesses acquired during overseas travel in 4 countries were resistant to quinolones. One S. sonnei PFGE pattern was traced to a multidrug-resistant isolate acquired overseas that had caused a multistate outbreak of shigellosis, suggesting global dissemination of a drug-resistant species. Resistance to certain drugs-for example, tetracycline-increased in both overseas- and domestic-acquired infections during the study period. The prevalence of resistance to macrolides (azithromycin) and third-generation cephalosporins (ceftriaxone) was less than 1%; however, efforts to better monitor changes in drug resistance over time combined with increased antimicrobial stewardship are essential at the local, national, and global levels.

Purpose: To evaluate the independent prognostic impact of the chest radiograph for mortality from community-acquired pneumonia requiring hospitalization. Methods: Chest radiographs of 67 patients with hospital-treated community-acquired pneumonia were analyzed with regard to the prognostic implications of radiographic patterns, extent and density of infiltrates, and its evolution during treatment. Results: Non-survivors had a significantly higher extent of infiltrates (p=0.008), density of infiltrates (p=0.05), and radiographic spread during follow-up within 48-72 hours (p=0.0001). In multivariate analysis, persistent or progressive infiltrates were associated with a 47fold increase, and persistent or progressive density of infiltrates with an 18fold increase in risk of mortality. The presence of both parameters could correctly predict 96% of survivors and 90% of non-survivors. Conclusions: The chest radiograph is an independent predictor of the severity of pneumonia. Both persistent or progressive infiltrates and persistent or progressive density of infiltrates are independently associated with mortality from community-acquired pneumonia. (orig.) [de

Cytokines IL-2 and IL-8 both participate in immune regulation. However, the relationship between polymorphisms in these two cytokines and the risk of acquired aplastic anemia (acquired AA) has not been explored. We selected five SNPs including rs11575812, rs2069772 and rs2069762 of IL-2, rs2227306 and rs2227543 of IL-8. SNaPshot genotyping was used to test the genotypes of IL-2 and IL-8 polymorphisms in a population of 101 acquired AA patients and 165 healthy controls. The rs2069762 G allele appeared to be a protective mutation, but no significant differences were found in other four SNPs. We also found that rs2069762 had an impact on the transcriptional regulation. It could be assumed that the rs2069762 polymorphism might reduce the risk of acquired aplastic anemia, while the remaining four SNPs might not contribute to susceptibility to acquired AA in a Chinese population. © 2017 The Author(s)Published by S.

Community acquired-Clostridium difficile infection (CDI) has increased also in children in the last years. To determine the incidence of community-acquired CDI and to understand whether Clostridium difficile could be considered a symptom-triggering pathogen in infants. A five-year retrospective analysis (January 2007-December 2011) of faecal specimens from 124 children hospitalized in the Niguarda Ca' Granda Hospital for prolonged or muco-haemorrhagic diarrhoea was carried out. Stool samples were evaluated for common infective causes of diarrhoea and for Clostridium difficile toxins. Patients with and without CDI were compared for clinical characteristics and known risk factors for infection. Twenty-two children with CDI were identified in 5 years. An increased incidence of community-acquired CDI was observed, ranging from 0.75 per 1000 hospitalizations in 2007 to 9.8 per 1000 hospitalizations in 2011. Antimicrobial treatment was successful in all 19 children in whom it was administered; 8/22 CDI-positive children were younger than 2 years. No statistically significant differences in clinical presentation were observed between patients with and without CDI, nor in patients with and without risk factors for CDI. Our study shows that Clostridium difficile infection is increasing and suggests a possible pathogenic role in the first 2 years of life. Copyright © 2015 Editrice Gastroenterologica Italiana S.r.l.

Electrical Signaling, Photosynthesis and Systemic Acquired Acclimation

Full Text Available Electrical signaling in higher plants is required for the appropriate intracellular and intercellular communication, stress responses, growth and development. In this review, we have focus on recent findings regarding the electrical signaling, as a major regulator of the systemic acquired acclimation (SAA and the systemic acquired resistance (SAR. The electric signaling on its own cannot confer the required specificity of information to trigger SAA and SAR, therefore, we have also discussed a number of other mechanisms and signaling systems that can operate in combination with electric signaling. We have emphasized the interrelation between ionic mechanism of electrical activity and regulation of photosynthesis, which is intrinsic to a proper induction of SAA and SAR. In a special way, we have summarized the role of non-photochemical quenching and its regulator PsbS. Further, redox status of the cell, calcium and hydraulic waves, hormonal circuits and stomatal aperture regulation have been considered as components of the signaling. Finally, a model of light-dependent mechanisms of electrical signaling propagation has been presented together with the systemic regulation of light-responsive genes encoding both, ion channels and proteins involved in regulation of their activity. Due to space limitations, we have not addressed many other important aspects of hormonal and ROS signaling, which were presented in a number of recent excellent reviews.

Acquisition of instrumental defense response with pain reinforcement uncertainty (25% reinforcement) induced the development of acquired helplessness in 50% rats. Acquired helplessness is characterized by the absence of responses to conditioned (light) and unconditioned stimuli (pain), minor response of plasma corticosterone to learning, gas markers of circulatory cerebral hypoxia (Delta A/V pO2 carotid artery/jugular vein), low sensitivity to severe hypobaric conditions, and high resistance of Purkinje cells in the cerebellum. Piracetam improved learning and prevented the development of acquired helplessness. Local changes in cerebral blood flow and energy deficit in neurons responsible for emotional stress during acquired helplessness impair adaptive capacity, but reduce energy consumption and protect neuronal structures.

This is the first published case report en Colombia about pseudomona pseudomallei community acquired pneumonia. This uncommon pathogen is from the epidemiological standpoint a very important one and medical community should be aware to look after it in those patients where no other etiological pathogen is recovered. A brief summary about epidemiology is showed, emphasizing those regions where it can be found. Likewise, comments about the differential diagnosis are important since it should be considered in those patients where tuberculosis is suspected. This is particularly representative for countries with high tuberculosis rates. Furthermore, a microbiological review is shown, emphasizing on isolation techniques, descriptions about therapeutics and other regarding treatment issues according international standards. Finally; a description about the clinical picture, laboratory findings, treatment and evolution of the case reported are shown for discussion

In Rwanda, many people are still mentally affected by the consequences of the genocide and yet mental health care facilities are scarce. While available literature explains the prevalence and consequences of mental disorders, there is lack of knowledge from low-income countries on health care seeking behavior due to common mental disorders. Therefore, this study sought to explore health care professionals' acquired experiences of barriers and facilitators that people with common mental disorders face when seeking mental health care services in Rwanda. A qualitative approach was applied and data was collected from six focus group discussions (FGDs) conducted in October 2012, including a total of 43 health care professionals, men and women in different health professions. The FGDs were performed at health facilities at different care levels. Data was analyzed using manifest and latent content analysis. The emerging theme "A constant struggle to receive mental health care for mental disorders" embraced a number of barriers and few facilitators at individual, family, community and structural levels that people faced when seeking mental health care services. Identified barriers people needed to overcome were: Poverty and lack of family support, Fear of stigmatization, Poor community awareness of mental disorders, Societal beliefs in traditional healers and prayers, Scarce resources in mental health care and Gender imbalance in care seeking behavior. The few facilitators to receive mental health care were: Collaboration between authorities and organizations in mental health and having a Family with awareness of mental disorders and health insurance. From a public health perspective, this study revealed important findings of the numerous barriers and the few facilitating factors available to people seeking health for mental disorders. Having a supportive family with awareness of mental disorders who also were equipped with a health insurance was perceived as vital for

Posttraumatic growth following acquired brain injury: A systematic review and meta-analysis

Directory of Open Access Journals (Sweden)

Elaine Louise Kinsella

2015-08-01

Full Text Available The idea that acquired brain injury (ABI caused by stroke, haemorrhage, infection or traumatic insult to the brain can result in posttraumatic growth (PTG for individuals is increasingly attracting psychological attention. However PTG also attracts controversy as a result of ambiguous empirical findings. The extent that demographic variables, injury factors, subjective beliefs, and psychological health are associated with PTG following ABI is not clear. Consequently, this systematic review and meta-analysis explores the correlates of variables within these four broad areas and PTG. From a total of 744 published studies addressing PTG in people with ABI, eight studies met inclusion criteria for detailed examination. Meta-analysis of these studies indicated that growth was related to employment, longer education, subjective beliefs about change post-injury, relationship status, older age, longer time since injury, and lower levels of depression. Results from homogeneity analyses indicated significant inter-study heterogeneity across variables. There is general support for the idea that people with ABI can experience growth, and that various demographics, injury-related variables, subjective beliefs and psychological health are related to growth. The contribution of social integration and the forming of new identities post-ABI to the experience of PTG is explored. These meta-analytic findings are however constrained by methodological limitations prevalent in the literature. Clinical and research implications are discussed with specific reference to community and collective factors that enable PTG.

Anecdotally, it has been reported that individuals with acquired prosopagnosia compensate for their inability to recognize faces by using other person identity cues such as hair, gait or the voice. Are they therefore superior at the use of non-face cues, specifically voices, to person identity? Here, we empirically measure person and object identity recognition in a patient with acquired prosopagnosia and object agnosia. We quantify person identity (face and voice) and object identity (car and horn) recognition for visual, auditory, and bimodal (visual and auditory) stimuli. The patient is unable to recognize faces or cars, consistent with his prosopagnosia and object agnosia, respectively. He is perfectly able to recognize people's voices and car horns and bimodal stimuli. These data show a reverse shift in the typical weighting of visual over auditory information for audiovisual stimuli in a compromised visual recognition system. Moreover, the patient shows selectively superior voice recognition compared to the controls revealing that two different stimulus domains, persons and objects, may not be equally affected by sensory adaptation effects. This also implies that person and object identity recognition are processed in separate pathways. These data demonstrate that an individual with acquired prosopagnosia and object agnosia can compensate for the visual impairment and become quite skilled at using spared aspects of sensory processing. In the case of acquired prosopagnosia it is advantageous to develop a superior use of voices for person identity recognition in everyday life. Copyright © 2010 Elsevier Ltd. All rights reserved.

Full Text Available Background. Hypothermal extracorporeal circulation has been used in cardiosurgery over 50 years. However, recent trials have not shown its predominant effect on the protection of the brain, lung, and myocardium in patients during surgery. We have presumed that when normothermal extracorporeal circulation used in patients with acquired heart disease, its pathophysiological effect on the body is comparable with that of hypothermal extracorporeal circulation. Subjects and methods. One hundred and forty patients who were to undergo acquired heart disease correction were randomized into two equal groups: that using hypothermal or normothermal extracorporeal circulation. Perioperative troponin I and NT-proBNP concentrations, postoperative clinical course, and hospital morbidity and mortality rates were estimated. Results. There were no significant differences in the concentrations of troponin I and NT-proBNP at the study stages. In the normothermal extracorporeal circulation group patients with isolated aortic stenosis, the concentration of troponin I was higher than that in the hypothermal extracorporeal circulation group. Analyzing the postoperative course indicated that the duration of mechanical ventilation was significantly lower in the hypothermal extracorporeal circulation group than in the normothermal extracorporeal circulation group. There were no differences in hospital complications and mortality rates. Conclusion. Hypothermal versus normothermal extracorporeal circulation in the correction of acquired heart diseases has no predominant effect on tro-ponin I and NT-proBNP concentrations, postoperative clinical course, and hospital complications and mortality rates. Key words: extracorporeal circulation, hypothermia, acquired heart disease, troponin I, NT-proBNP.

Full Text Available Understanding language learning in later life can elucidate how linguistic experiences and age-specific cognitive skills can be leveraged for language acquisition, providing insight into how lifelong experiences configure our learning capacity. In this study, we examined to what extent acquisition and maintenance of a non-native language (English is scaffolded by cognitive skills and previous linguistic experiences in older adults; and to what extent these cognitive/linguistic factors predict older learners’ success in acquiring novel functional language. We recruited 53 participants who were native speakers of Mandarin, Spanish, Tagalog, and Somali, had continued to learn English as adults, and were currently exposed to majority-English contexts. To identify contributors to participants’ English skills, we administered a language history and self-reported proficiency interview, brief cognitive testing, and verbal fluency tasks in L1 and English. We found that digit span and orientation measures were cognitive predictors of English proficiency, while similarity of known languages to English, L1 skills, and English language exposure were linguistic predictors of English skills. To examine participants’ ability to maintain language knowledge and to learn new functional English, we also conducted a preliminary longitudinal service-based study in a subset of 19 participants using our Specific-Purpose English Communication System for Seniors (SPECSS curriculum. In this subset of SPECSS learners, we identified digit span and orientation, but not age, as cognitive predictors of short-term language maintenance. Further, better novel English learning as a result of our curriculum was observed in learners whose other known languages were less similar to English. Findings inform best practices in developing language curricula for older adults, and help generate new hypotheses on preparedness for language learning across the adult lifespan with a

Knollman-Porter, Kelly

2008-01-01

Apraxia of speech (AOS) is an acquired adult neurogenic communication disorder that often occurs following stroke. The purpose of this article is to review current research studies addressing the diagnostic and therapeutic management of AOS. Traditional definitions and characteristics are compared with current features that assist in the differential diagnosis of AOS. Prognostic indicators are reviewed in addition to how neuroplasticity may impact treatment in chronic AOS. Treatment techniques discussed include the articulatory kinematic approach (AKA), use of augmentative/alternative communication devices, intersystemic facilitation/reorganization, and constraint-induced therapy. Finally, the need to address functional communication through support groups, outside the therapeutic environment, is discussed.

How implicitly activated and explicitly acquired knowledge contribute to the effectiveness of retrieval cues.

Nelson, Douglas L; Fisher, Serena L; Akirmak, Umit

2007-12-01

The extralist cued recall task simulates everyday reminding because a memory is encoded on the fly and retrieved later by an unexpected cue. Target words are studied individually, and recall is cued by associatively related words having preexisting forward links to them. In Experiments 1 and 2, forward cue-to-target and backward target-to-cue strengths were varied over an extended range in order to determine how these two sources of strength are related and which source has a greater effect. Forward and backward strengths had additive effects on recall, with forward strength having a consistently larger effect. The PIER2 model accurately predicted these findings, but a plausible generation-recognition version of the model, called PIER.GR, could not. In Experiment 3, forward and backward strengths, level of processing, and study time were varied in order to determine how preexisting lexical knowledge is related to knowledge acquired during the study episode. The main finding indicates that preexisting knowledge and episodic knowledge have additive effects on extralist cued recall. PIER2 can explain these findings because it assumes that these sources of strength contribute independently to recall, whereas the eSAM model cannot explain the findings because it assumes that the sources of strength are multiplicatively related.

Experience and lessons learned in the assessment of safety justifications for experiments mounted in research reactors

International Nuclear Information System (INIS)

Cox, R.F.

1990-01-01

Some experiments in research reactors are arguably a risky undertaking due to their uncertain outcome. The justifications for such experiments require careful assessment to validate their undertaking. The public, the operators and the installation itself must be safeguarded. Assessment of the potential risk is an acquired skill but in doing so the route can be eased by learning from the lessons experience can teach. This paper, essentially for the usage of safety managers, sets out some of the issues relating to the assessment process gained from our experience over a few tens of years in the assessment of experiments. Many of the conclusions reached may appear all too obvious viewed in retrospect, but they were not necessarily clear at the time. Those organizations setting up assessment teams may find some of the conclusions of value such that their proposed management system can embrace methodologies for assessment that can avoid or lessen the impact of some of the pitfalls we have tried to identify. Failure to recognise some of these points may run the risk of delayed clearances, dilated timescales and cost overruns. It is in the hope of reducing all these penalties that we offer our experiences

Mesenchymal Stem Cell Benefits Observed in Bone Marrow Failure and Acquired Aplastic Anemia

Gonzaga, Vivian Fonseca; Lisboa, Gustavo Sabino; Frare, Eduardo Osório

2017-01-01

Acquired aplastic anemia (AA) is a type of bone marrow failure (BMF) syndrome characterized by partial or total bone marrow (BM) destruction resulting in peripheral blood (PB) pancytopenia, which is the reduction in the number of red blood cells (RBC) and white blood cells (WBC), as well as platelets (PLT). The first-line treatment option of AA is given by hematopoietic stem cell (HSCs) transplant and/or immunosuppressive (IS) drug administration. Some patients did not respond to the treatment and remain pancytopenic following IS drugs. The studies are in progress to test the efficacy of adoptive cellular therapies as mesenchymal stem cells (MSCs), which confer low immunogenicity and are reliable allogeneic transplants in refractory severe aplastic anemia (SAA) cases. Moreover, bone marrow stromal cells (BMSC) constitute an essential component of the hematopoietic niche, responsible for stimulating and enhancing the proliferation of HSCs by secreting regulatory molecules and cytokines, providing stimulus to natural BM microenvironment for hematopoiesis. This review summarizes scientific evidences of the hematopoiesis improvements after MSC transplant, observed in acquired AA/BMF animal models as well as in patients with acquired AA. Additionally, we discuss the direct and indirect contribution of MSCs to the pathogenesis of acquired AA. PMID:29333168

To investigate the possible association between acquired ectropion uveae and blunt trauma to the eye. We present 3 cases of acquired ectropion uveae that occurred after blunt trauma to the eye. There are no previously published data on possible association of these conditions. A retrospective review was conducted of patients with ectropion uveae and eye injury at University Eye Hospital over a 10-year period (2006-2016). We analyzed medical records and clinical findings. Three eyes of 3 male patients with ocular trauma and ectropion uveae, ages 71, 68, and 5 years, were reviewed. The period between the eye injury and the diagnosis of ectropion uveae ranged from 10 to 36 months. All 3 eyes developed clinical evidence of secondary glaucoma with moderately to severely elevated intraocular pressure (IOP) (ranging from 29 to 48 mm Hg). Surgical treatment (trabeculectomy) was needed in 2 cases in order to control secondary glaucoma and conservative treatment was sufficient in 1 case. Mean patient follow-up was 19.3 ± 4.6 months. Trauma can be considered as a cause of acquired ectropion uveae. Acquired ectropion uveae following eye trauma may be associated with significant increase in IOP. All patients in our series had secondary glaucoma and 2 of 3 required surgical treatment for IOP control.

Community acquired urinary tract infection: etiology and bacterial susceptibility

Dias Neto José Anastácio

2003-01-01

Full Text Available PURPOSE: Urinary tract infections (UTI are one of the most common infectious diseases diagnosed. UTI account for a large proportion of antibacterial drug consumption and have large socio-economic impacts. Since the majority of the treatments begins or is done completely empirically, the knowledge of the organisms, their epidemiological characteristics and their antibacterial susceptibility that may vary with time is mandatory. OBJECTIVE: The aim of this study was to report the prevalence of uropathogens and their antibiotic susceptibility of the community acquired UTI diagnosed in our institution and to provide a national data. METHODS: We analyzed retrospectively the results of urine cultures of 402 patients that had community acquired urinary tract infection in the year of 2003. RESULTS: The mean age of the patients in this study was 45.34 ± 23.56 (SD years. There were 242 (60.2% females and 160 (39.8% males. The most commonly isolated organism was Escherichia coli (58%. Klebsiella sp. (8.4% and Enterococcus sp.(7.9% were reported as the next most common organisms. Of all bacteria isolated from community acquired UTI, only 37% were sensitive to ampicillin, 51% to cefalothin and 52% to trimethoprim/sulfamethoxazole. The highest levels of susceptibility were to imipenem (96%, ceftriaxone (90%, amikacin (90%, gentamicin (88%, levofloxacin (86%, ciprofloxacin (73%, nitrofurantoin (77% and norfloxacin (75%. CONCLUSION: Gram-negative agents are the most common cause of UTI. Fluoroquinolones remains the choice among the orally administered antibiotics, followed by nitrofurantoin, second and third generation cephalosporins. For severe disease that require parenteral antibiotics the choice should be aminoglycosides, third generation cephalosporins, fluoroquinolones or imipenem, which were the most effective.

Data acquisition and experiment control system for high-data-rate experiments at the National Synchrotron Light Source

Alberi, J.L.; Stubblefield, F.W.

1981-11-01

A data acquisition and experiment control system for experiments at the Biology Small-Angle X-ray Scattering Station at the National Synchrotron Light Source has been developed based on a multiprocessor, functionally distributed architecture. The system controls an x-ray monochromator and spectrometer and acquires data from any one of three position-sensitive x-ray detectors. The average data rate from the position-sensitive detector is approx. 10 6 events/sec. Data is stored in a one megaword histogramming memory. The experiments at this Station require that x-ray diffraction patterns be correlated with timed stimuli at the sample. Therefore, depending on which detector is in use, up to 10 3 time-correlated diffraction patterns may be held in the system memory simultaneously. The operation of the system is functionally distributed over four processors communicating via a multiport memory

Operational experience acquired in radioactive waste compaction

The low-level radioactive waste scrapping facility in the KfK decontamination division was commissioned in 1983. Non-combustible residues and removed system components of low activity, but which are to be handled and disposed of as radioactive waste are in drums, casks or containers delivered to the facility. The waste usually undergoes pretreatment in a crusher, with the volume being definitively reduced at a pressure of 690 bar in the high-pressure compactor. In 1990, the overhead-crane was refurbished for remote control handling in the scrapping caisson. The parts to undergo scrapping are unpacked in the material lock, and then go into the scrapping caisson. It is possible to use here various mechanical and thermal methods to dismantle the respective parts. But most of the parts to undergo scrapping are such as that it is possible to directly pretreat them in the crusher. The obtained scrap is loaded into 180-liter drums. Most of the machinery in the caisson is manually operated. The operating crew enters the caisson in fully ventilated protective overalls. The drums filled with the scrap then go to the high-pressure compactor in the caisson. The compacts are temporarily stored, until recalled depending on their height and filled into drums such as that optimal drum filling is guaranteed

Kim, Yoonjung

2017-10-01

The aim of this study was to explore experiences of positive growth in long-term childhood cancer survivors, from their perspective. Fifteen long-term survivors of childhood cancer provided descriptions of their experiences. Data were collected through face-to-face interviews and the analysis was based on Giorgi's phenomenological research method. The analysis of positive growth experienced by long-term childhood cancer survivors revealed three themes: self-directed life, normalcy in life, and inner maturity. Long-term survivors defined positive growth as a successful transition to a self-satisfactory life based on motivation acquired through their cancer experience and on subjective goal-setting, as well as becoming cancer-free and living a normal life within society. They seemed to have acquired optimistic, flexible, active attitudes toward life while demonstrating profound gratefulness and consideration of people around them, as well as prudent approaches to health. The findings of this study verified that long-term survivors of childhood cancer have grown positively due to their negative past experience. We expect these findings to contribute to the development of programs that promote positive growth in long-term childhood cancer survivors. Copyright © 2017 Elsevier Ltd. All rights reserved.

Lappalainen, Jouni; Rosqvist, Juho

2015-04-01

This paper explores the ways students perceive the transfer of learned knowledge to new situations - often a surprisingly difficult prospect. The novel aspect compared to the traditional transfer studies is that the learning phase is not a part of the experiment itself. The intention was only to activate acquired knowledge relevant to the transfer target using a short primer immediately prior to the situation where the knowledge was to be applied. Eight volunteer students from either mathematics or computer science curricula were given a task of designing an adder circuit using logic gates: a new context in which to apply knowledge of binary arithmetic and Boolean algebra. The results of a phenomenographic classification of the views presented by the students in their post-experiment interviews are reported. The degree to which the students were conscious of the acquired knowledge they employed and how they applied it in a new context emerged as the differentiating factors.

Although pediatric patients are sometimes included in studies about visual problems in patients with acquired brain injury (ABI), few studies deal solely with children. Unlike studies dealing with adult patients, in which mechanisms of brain injury are divided into cerebral vascular accident (CVA) and traumatic brain injury (TBI), studies on pediatric patients deal almost exclusively with traumatic brain injury, specifically caused by accidents. Here we report on the vision problems of 4 pediatric patients, ages 3 to 18 years, who were examined in the ophthalmology/optometry clinic at a children's hospital. All patients had an internally caused brain injury and after the initial insult manifested problems in at least one of the following areas: acuity, binocularity, motility (tracking or saccades), accommodation, visual fields, and visual perceptual skills. Pediatric patients can suffer from a variety of oculo-visual problems after the onset of head injury. These patients may or may not be symptomatic and can benefit from optometric intervention.

Schock, Richard W.

1987-01-01

The purpose of the Solar Array Flight Dynamic Experiment (SAFDE) is to demonstrate the feasibility of on-orbit measurement and ground processing of large space structures' dynamic characteristics. Test definition or verification provides the dynamic characteristic accuracy required for control systems use. An illumination/measurement system was developed to fly on space shuttle flight STS-41D. The system was designed to dynamically evaluate a large solar array called the Solar Array Flight Experiment (SAFE) that had been scheduled for this flight. The SAFDE system consisted of a set of laser diode illuminators, retroreflective targets, an intelligent star tracker receiver and the associated equipment to power, condition, and record the results. In six tests on STS-41D, data was successfully acquired from 18 retroreflector targets and ground processed, post flight, to define the solar array's dynamic characteristic. The flight experiment proved the viability of on-orbit test definition of large space structures dynamic characteristics. Future large space structures controllability should be greatly enhanced by this capability.

Acquired immunologic tolerance in chimeras and histocompatibility factors in cattle and their relationship to those in humans. Final report. [Gamma radiation

Energy Technology Data Exchange (ETDEWEB)

Stone, W.H.

1976-03-01

During the course of this project we have studied 35 pairs of chimeric cattle twins. It is now clear that fractionated doses of whole-body /sup 60/Co irradiation can cause marked shifts in the proportions of the two erythrocyte populations that make up the chimeric mixture. However, it has not been possible to eliminate one of the two cell types and thus abrogate the acquired immunologic tolerance. The results of our extensive skin-grafting experiments are remarkable because they show that a chimeric twin may mount a sufficient immune response to reject its cotwin's skin while remaining completely tolerant to erythropoietic elements of its cotwin. In conjunction with these studies, we have acquired sufficient data to define a major histocompatibility locus in cattle using alloimmune anti-lymphocyte typing sera as well as the mixed lymphocyte culture technic. This project has also yielded a considerable number of new immunogenetic parameters for cattle, monkeys and birds. Such parameters are useful for basic and applied studies in immunology.

Details acquired from medical history and patients’ experience of empathy – two sides of the same coin

Science.gov (United States)

2013-01-01

Background History taking and empathetic communication are two important aspects in successful physician-patient interaction. Gathering important information from the patient’s medical history is needed for effective clinical decision making while empathy is relevant for patient satisfaction. We wanted to investigate whether medical students near graduation are able to combine both skills as required in daily medical practice. Methods Thirty near graduates from Hamburg Medical School participated in an assessment for clinical competences including a consultation hour with five standardized patients. Each patient interview was videotaped and standardized patients rated participants with the CARE questionnaire for consultation and relational empathy. All videotaped interviews were rated with a checklist based on the number of important medical aspects for each case. Data were analysed with the linear mixed model to correct for random effects. Regression analysis was performed to look for correlations between the number of questions asked by a participant and their respective empathy rating. Results Of the 123 aspects that could have been gathered in total, students only requested 56.4% (95% CI 53.5-59.3). While no difference between male and female participants was found, a significant difference (p sides of the coin of history taking. While both skills have to be acquired during medical school training with particular focus on their respective learning objectives, medical students need to be provided with additional learning and feedback opportunities where they can be observed exercising both skills combined as required in physicians’ daily practice.

Kaposi's sarcoma is frequently found in association with acquired immunodeficiency syndrome (AIDS). We report on radiotherapy for patients with AIDS-related Kaposi's sarcoma at Tokyo Metropolitan Komagome Hospital. Between April 1991 and May 1997, radiotherapy was given to 11 lesions in eight men with AIDS-related Kaposi's sarcoma to relieve their symptoms. The lesions involved the head and neck region, the legs, and the gastrointestinal tract. Radiotherapy was carried out with 4-MV photon through parallel opposed field or high energy electrons. Total doses ranged from 20 to 38 Gy, with a median of 30 Gy, delivered in 2- to 3-Gy fractions. Four patients were given other treatments prior to the radiotherapy. Acute reaction was evaluated according to the modified acute radiation morbidity scoring criteria of the Radiation Therapy Oncology Group (RTOG). Radiotherapy had relieved the symptoms in all patients at completion of this therapy. Lesions that involved the hard palate and vocal cords had completely disappeared. The lesions that received radiotherapy were controlled without symptoms until the patients died. Patients who had the head and neck region treated exhibited severe acute mucosal reaction (at a dose of 30 Gy, there was grade 2 morbidity by modified RTOG criteria, in two patients, and grade 3 in three patients) although the radiation therapy was completed for these patients. Radiotherapy promises a favorable outcome for symptom relief in AIDS-related Kaposi's sarcoma. (author)

Chlamydia trachomatis co-opts GBF1 and CERT to acquire host sphingomyelin for distinct roles during intracellular development.

Directory of Open Access Journals (Sweden)

Cherilyn A Elwell

2011-09-01

Full Text Available The strain designated Chlamydia trachomatis serovar that was used for experiments in this paper is Chlamydia muridarum, a species closely related to C. trachomatis (and formerly termed the Mouse Pneumonitis strain of C. trachomatis. [corrected]. The obligate intracellular pathogen Chlamydia trachomatis replicates within a membrane-bound inclusion that acquires host sphingomyelin (SM, a process that is essential for replication as well as inclusion biogenesis. Previous studies demonstrate that SM is acquired by a Brefeldin A (BFA-sensitive vesicular trafficking pathway, although paradoxically, this pathway is dispensable for bacterial replication. This finding suggests that other lipid transport mechanisms are involved in the acquisition of host SM. In this work, we interrogated the role of specific components of BFA-sensitive and BFA-insensitive lipid trafficking pathways to define their contribution in SM acquisition during infection. We found that C. trachomatis hijacks components of both vesicular and non-vesicular lipid trafficking pathways for SM acquisition but that the SM obtained from these separate pathways is being utilized by the pathogen in different ways. We show that C. trachomatis selectively co-opts only one of the three known BFA targets, GBF1, a regulator of Arf1-dependent vesicular trafficking within the early secretory pathway for vesicle-mediated SM acquisition. The Arf1/GBF1-dependent pathway of SM acquisition is essential for inclusion membrane growth and stability but is not required for bacterial replication. In contrast, we show that C. trachomatis co-opts CERT, a lipid transfer protein that is a key component in non-vesicular ER to trans-Golgi trafficking of ceramide (the precursor for SM, for C. trachomatis replication. We demonstrate that C. trachomatis recruits CERT, its ER binding partner, VAP-A, and SM synthases, SMS1 and SMS2, to the inclusion and propose that these proteins establish an on-site SM biosynthetic

Swine dysentery (SD) is an economically important disease for which antimicrobial treatment still occupies an important place to control outbreaks. However, acquired antimicrobial resistance is increasingly observed in Brachyspira hyodysenteriae. In this study, the Minimal Inhibitory Concentrations (MIC) of six antimicrobial compounds for 30 recent Belgian B. hyodysenteriae isolates were determined using a broth microdilution method. In addition, relevant regions of the 16S rRNA, 23S rRNA and the L3 protein encoding genes were sequenced to reveal mutations associated with acquired resistance. Finally, a phylogeny was reconstructed using minimal spanning tree analysis of multi locus sequence typing of the isolates. For lincomycin, doxycycline, tylosin and tylvalosin, at least 70% of the isolates did not belong to the wild-type population and were considered to have acquired resistance. For valnemulin and tiamulin, this was over 50%. In all isolates with acquired resistance to doxycycline, the G1058C mutation was present in their 16S rRNA gene. All isolates showing acquired resistance to lincomycin and both macrolides displayed the A2058T mutation in their 23S rRNA gene. Other mutations in this gene and the N148S mutation in the L3 protein were present in both wild-type isolates and isolates considered to have acquired resistance. Multi locus sequence analysis revealed a previously undescribed clonal complex, with 4 novel sequence types in which the majority of isolates showed acquired resistance to all tested antimicrobial products. In conclusion, acquired antimicrobial resistance is widespread among Belgian B. hyodysenteriae isolates. The emergence of multi-resistant clonal complexes can pose a threat to swine industry.

Jaqueline de Carvalho Rodrigues

Full Text Available OBJECTIVE: This study aimed to assess the strengths and difficulties in word and pseudoword writing in adults with left- and right-hemisphere strokes, and discuss the profiles of acquired dysgraphia in these individuals.METHODS: The profiles of six adults with acquired dysgraphia in left- or right-hemisphere strokes were investigated by comparing their performance on word and pseudoword writing tasks against that of neurologically healthy adults. A case series analysis was performed on the patients whose impairments on the task were indicative of acquired dysgraphia.RESULTS: Two patients were diagnosed with lexical dysgraphia (one with left hemisphere damage, and the other with right hemisphere damage, one with phonological dysgraphia, another patient with peripheral dysgraphia, one patient with mixed dysgraphia and the last with dysgraphia due to damage to the graphemic buffer. The latter patients all had left-hemisphere damage (LHD. The patterns of impairment observed in each patient were discussed based on the dual-route model of writing.CONCLUSION: The fact that most patients had LHD rather than right-hemisphere damage (RHD highlights the importance of the former structure for word processing. However, the fact that lexical dysgraphia was also diagnosed in a patient with RHD suggests that these individuals may develop writing impairments due to damage to the lexical route, leading to heavier reliance on phonological processing. Our results are of significant importance to the planning of writing interventions in neuropsychology.

Prevention of hospital-acquired hyponatraemia

for prevention of hospital-acquired hyponatraemia is an understanding of what determines plasma sodium concentration (P-[Na(+) ]) in the individual patient. P-[Na(+) ] is determined by balances of water and cations according to Edelman. This paper discusses the mechanisms influencing water and cation balances....... In the hospitalised patient, non-osmotic antidiuretic hormone secretion is frequent and results in a reduced renal electrolyte-free water clearance (EFWC). This condition puts the patient at risk of hyponatraemia upon infusion of fluids that are hypotonic such as 5% glucose, Darrow-glucose, NaKglucose and 0.45% Na......Cl in 5% glucose. It is suggested that individualised fluid therapy includes the following: Firstly, bolus therapy with Ringer-acetate/Ringer-lactate/0.9% NaCl in the hypovolaemic patient to minimise the risk of fluid under-/overload. Secondly, P-[Na(+) ] should be monitored together with the balances...

Acquired auditory-visual synesthesia: A window to early cross-modal sensory interactions

Pegah Afra

2009-01-01

Full Text Available Pegah Afra, Michael Funke, Fumisuke MatsuoDepartment of Neurology, University of Utah, Salt Lake City, UT, USAAbstract: Synesthesia is experienced when sensory stimulation of one sensory modality elicits an involuntary sensation in another sensory modality. Auditory-visual synesthesia occurs when auditory stimuli elicit visual sensations. It has developmental, induced and acquired varieties. The acquired variety has been reported in association with deafferentation of the visual system as well as temporal lobe pathology with intact visual pathways. The induced variety has been reported in experimental and post-surgical blindfolding, as well as intake of hallucinogenic or psychedelics. Although in humans there is no known anatomical pathway connecting auditory areas to primary and/or early visual association areas, there is imaging and neurophysiologic evidence to the presence of early cross modal interactions between the auditory and visual sensory pathways. Synesthesia may be a window of opportunity to study these cross modal interactions. Here we review the existing literature in the acquired and induced auditory-visual synesthesias and discuss the possible neural mechanisms.Keywords: synesthesia, auditory-visual, cross modal

Iterative reconstruction with attenuation compensation from cone-beam projections acquired via nonplanar orbits

International Nuclear Information System (INIS)

Zeng, G.L.; Weng, Y.; Gullberg, G.T.

1997-01-01

Single photon emission computed tomography (SPECT) imaging with cone-beam collimators provides improved sensitivity and spatial resolution for imaging small objects with large field-of-view detectors. It is known that Tuy's cone-beam data sufficiency condition must be met to obtain artifact-free reconstructions. Even though Tuy's condition was derived for an attenuation-free situation, the authors hypothesize that an artifact-free reconstruction can be obtained even if the cone-beam data are attenuated, provided the imaging orbit satisfies Tuy's condition and the exact attenuation map is known. In the authors' studies, emission data are acquired using nonplanar circle-and-line orbits to acquire cone-beam data for tomographic reconstructions. An extended iterative ML-EM (maximum likelihood-expectation maximization) reconstruction algorithm is derived and used to reconstruct projection data with either a pre-acquired or assumed attenuation map. Quantitative accuracy of the attenuation corrected emission reconstruction is significantly improved

In the second part of this publication, we describe some additional findings in cases of sternocostoclavicular hyperostosis (SCCH). These include focal hyperostosis of the spine, in the pelvis and in the extremities and psoriatric skin lesions and severe forms of acne (acne conglobata, acne fulminans). An analysis of our 13 patients and of the relevant literature indicates that the hyperostosis is due to increased bone metabolism and heterotopic ossification of fibrous tissue and that these are the pathogenic bases of the changes in the axial skeleton, the pelvis and the bones of the extremities. We have suggested a scheme which would categorise the syndrom into complete, incomplete and possibly acquired forms. (orig./GDG) [de

Introduction The International Society for Sexual Medicine (ISSM) Ad Hoc Committee for the Definition of Premature Ejaculation developed the first evidence-based definition for lifelong premature ejaculation (PE) in 2007 and concluded that there were insufficient published objective data at that time to develop a definition for acquired PE. Aim The aim of this article is to review and critique the current literature and develop a contemporary, evidence-based definition for acquired PE and/or a unified definition for both lifelong and acquired PE. Methods In April 2013, the ISSM convened a second Ad Hoc Committee for the Definition of Premature Ejaculation in Bangalore, India. The same evidence-based systematic approach to literature search, retrieval, and evaluation used by the original committee was adopted. Results The committee unanimously agreed that men with lifelong and acquired PE appear to share the dimensions of short ejaculatory latency, reduced or absent perceived ejaculatory control, and the presence of negative personal consequences. Men with acquired PE are older, have higher incidences of erectile dysfunction, comorbid disease, and cardiovascular risk factors, and have a longer intravaginal ejaculation latency time (IELT) as compared with men with lifelong PE. A self-estimated or stopwatch IELT of 3 minutes was identified as a valid IELT cut-off for diagnosing acquired PE. On this basis, the committee agreed on a unified definition of both acquired and lifelong PE as a male sexual dysfunction characterized by (i) ejaculation that always or nearly always occurs prior to or within about 1 minute of vaginal penetration from the first sexual experience (lifelong PE) or a clinically significant and bothersome reduction in latency time, often to about 3 minutes or less (acquired PE); (ii) the inability to delay ejaculation on all or nearly all vaginal penetrations; and (iii) negative personal consequences, such as distress, bother, frustration, and/or the

Full Text Available A merger can be defined as the economical and legal integration of two or more firms. On the other hand, an acquisiton is the transfer of all asssets and liabilities of the target firm to the acquiring firm. In the literature, merger and acquisition concepts can be used interchangeably. Firms tend to merge for the sake of creating snergy, competitive advantage, diversification, increasing firm value etc. Mergers and acquisitions are sometimes in favour of acquiring firms’ stock holders and sometimes target firms’ stock holders. Merger gains change, depending on the type of the merger and form of payment. In this study, mergers that occured through the permission of Capital Market Board have been used for the analyses. Of the mergers which have the permission, acquiring firms that are listed on Istanbul Stock Exchange have been considered and postacquisition buy and hold abnormal returns and cumulative abnormal returns have been calculated. It is concluded that postacquisition abnormal returns aren’t statistically significant. On the other hand, 1 month, 3 month, 6 month, 1 year and 2 year buy and hold abnormal returns and cumulative abnormal returns of the acquiring firms that use different payment methods are not statistically different from each other, on the basis of same return horizon. Two different methods of abnormal return calculation don’t make any difference in postacquisition abnormal returns, either.

Ways to engage the recipient in the media discourse, accompanying promotional activities for the film – understood in the category of marketing product – can be traced back to the example of two movies – The Blair Witch Project and The Dark Knight, which − due to an innovative approach to the subject of promotion and engage potential viewers – materialized as unusual in compared to traditional marketing, contributing to the spectacular box office success, acquiring new recipients, creating or expanding existing film fan clubs and to changes in film marketing, which today extends or reinterpreted these schemes of immersion.

Structural synaptic plasticity in the hippocampus induced by spatial experience and its implications in information processing.

Science.gov (United States)

Carasatorre, M; Ramírez-Amaya, V; Díaz Cintra, S

2016-10-01

Long-lasting memory formation requires that groups of neurons processing new information develop the ability to reproduce the patterns of neural activity acquired by experience. Changes in synaptic efficiency let neurons organise to form ensembles that repeat certain activity patterns again and again. Among other changes in synaptic plasticity, structural modifications tend to be long-lasting which suggests that they underlie long-term memory. There is a large body of evidence supporting that experience promotes changes in the synaptic structure, particularly in the hippocampus. Structural changes to the hippocampus may be functionally implicated in stabilising acquired memories and encoding new information. Copyright © 2012 Sociedad Española de Neurología.

Full Text Available Background: Patients with congenital and acquired hemiparesis incur long-term functional deficits, among which the loss of prehension that may impact their functional independence. Identifying, understanding and comparing the underlying mechanisms of prehension impairments represent an opportunity to better adapt neurorehabilitationObjective: The present review aims to provide a better understanding of precision grip deficits in congenital and acquired hemiparesis and to determine whether the severity and type of fine motor control impairments depend on whether or not the lesions are congenital or acquired in adulthood. Methods: Using combinations of the following key words: fingertip force, grip force, precision grip, cerebral palsy, stroke, pubmed and Scopus databases were used to search studies from 1984 to 2013. Results: Individuals with both congenital and acquired hemiparesis were able to some extent to use anticipatory motor control in precision grip tasks, even if this control was impaired in the paretic hand. In both congenital or acquired hemiparesis, the ability to plan efficient anticipatory motor control when the less-affected hand is used provides a possibility to remediate impairments in anticipatory motor control of the paretic hand. Conclusion: Surprisingly we observed very few differences between the results of studies in children with congenital hemiplegia and stroke patients. We suggest that the underlying specific strategies of neurorehabilitation developed for each one could benefit the other.

2017-01-01

Non-small-cell lung cancer patients with activating epidermal growth factor receptor (EGFR) mutations typically benefit from EGFR tyrosine kinase inhibitor treatment. However, virtually all patients succumb to acquired EGFR tyrosine kinase inhibitor resistance that occurs via diverse mechanisms....... The diversity and unpredictability of EGFR tyrosine kinase inhibitor resistance mechanisms presents a challenge for developing new treatments to overcome EGFR tyrosine kinase inhibitor resistance. Here, we show that Akt activation is a convergent feature of acquired EGFR tyrosine kinase inhibitor resistance......, across a spectrum of diverse, established upstream resistance mechanisms. Combined treatment with an EGFR tyrosine kinase inhibitor and Akt inhibitor causes apoptosis and synergistic growth inhibition in multiple EGFR tyrosine kinase inhibitor-resistant non-small-cell lung cancer models. Moreover...

New entrants to a market tend to be superior to incumbents in originating radical innovations. We provide a new explanation for this phenomenon, based on markets for technology. It applies in industries where successful entrepreneurial firms, or their technologies, are acquired by incumbents...... that then commercialize the innovation. To this end we analyze an innovation game between one incumbent and a large number of entrants. In the first stage, firms compete to develop innovations of high quality. They do so by choosing, at equal cost, the success probability of their R&D approach, where a lower probability...... the incumbent performs the least radical project. Entrants pick pairwise different projects; the bigger the number of entrants, the more radical the most radical project. Generally, entrants tend to choose more radical R&D approaches and generate the highest value innovation in case of success. We illustrate...
