    Full Text Available CONTEXTO: Experiências de quase morte (EQM são experiências vívidas, realísticas, que frequentemente promovem mudanças profundas na vida de pessoas que estiveram fisiológica ou psicologicamente próximas da morte. As EQM por vezes ocorrem durante uma parada cardíaca, na ausência de atividade cerebral detectável. OBJETIVO: Revisar os estudos prospectivos de EQM induzidas por paradas cardíacas e examinar as implicações desses estudos para o conceito de mente não local. MÉTODO: PubMed foi a principal base de dados utilizada para esta revisão. Os termos-chave da busca incluíram "parada cardíaca", "experiências de quase morte", "fisiologia da experiência de quase morte" e "experiências fora do corpo verídicas". RESULTADOS: Vários estudos prospectivos mostram incidência média de 10% a 20% de EQM induzidas por paradas cardíacas, independentemente de aspectos sociodemográficos, sexo, religião ou quaisquer parâmetros médicos, fisiológicos ou farmacológicos consistentes. Pessoas que passaram por EQM são mais propensas a mudanças de vida positivas que podem durar muitos anos após a experiência do que aquelas que não a tiveram. CONCLUSÕES: As teorias fisicalistas da mente não são capazes de explicar como pessoas que tiveram EQM podem vivenciar - enquanto seus corações estão parados e sua atividade cerebral aparentemente ausente - pensamentos vívidos e complexos e adquirir informações verídicas a respeito de objetos ou eventos distantes de seus corpos. As EQM em paradas cardíacas sugerem que a mente é não local, isto é, não é gerada pelo cérebro e não está confinada a ele ou ao corpo.

    Full Text Available One of the variables that influence motor learning is the learner’s previous experience, which may provide perceptual and motor elements to be transferred to a novel motor skill. For swimming skills, several motor experiences may prove effective. Purpose. The aim was to analyse the influence of previous experience in playing in water, swimming lessons, and music or dance lessons on learning the breaststroke kick. Methods. The study involved 39 Physical Education students possessing basic swimming skills, but not the breaststroke, who performed 400 acquisition trials followed by 50 retention and 50 transfer trials, during which stroke index as well as rhythmic and spatial configuration indices were mapped, and answered a yes/no questionnaire regarding previous experience. Data were analysed by ANOVA (p = 0.05 and the effect size (Cohen’s d ≥0.8 indicating large effect size. Results. The whole sample improved their stroke index and spatial configuration index, but not their rhythmic configuration index. Although differences between groups were not significant, two types of experience showed large practical effects on learning: childhood water playing experience only showed major practically relevant positive effects, and no experience in any of the three fields hampered the learning process. Conclusions. The results point towards diverse impact of previous experience regarding rhythmic activities, swimming lessons, and especially with playing in water during childhood, on learning the breaststroke kick.

    Reports of poor nursing care have focused attention on values based selection of candidates onto nursing programmes. Values based selection lacks clarity and valid measures. Previous caring experience might lead to better care. Emotional intelligence (EI) might be associated with performance, is conceptualised and measurable. To examine the impact of 1) previous caring experience, 2) emotional intelligence 3) social connection scores on performance and retention in a cohort of first year nursing and midwifery students in Scotland. A longitudinal, quasi experimental design. Adult and mental health nursing, and midwifery programmes in a Scottish University. Adult, mental health and midwifery students (n=598) completed the Trait Emotional Intelligence Questionnaire-short form and Schutte's Emotional Intelligence Scale on entry to their programmes at a Scottish University, alongside demographic and previous caring experience data. Social connection was calculated from a subset of questions identified within the TEIQue-SF in a prior factor and Rasch analysis. Student performance was calculated as the mean mark across the year. Withdrawal data were gathered. 598 students completed baseline measures. 315 students declared previous caring experience, 277 not. An independent-samples t-test identified that those without previous caring experience scored higher on performance (57.33±11.38) than those with previous caring experience (54.87±11.19), a statistically significant difference of 2.47 (95% CI, 0.54 to 4.38), t(533)=2.52, p=.012. Emotional intelligence scores were not associated with performance. Social connection scores for those withdrawing (mean rank=249) and those remaining (mean rank=304.75) were statistically significantly different, U=15,300, z=-2.61, p$_amp_$lt;0.009. Previous caring experience led to worse performance in this cohort. Emotional intelligence was not a useful indicator of performance. Lower scores on the social connection factor were associated

    Full Text Available Abstract Background Foraging behaviour is an essential ecological process linking different trophic levels. A central assumption of foraging theory is that food selection maximises the fitness of the consumer. It remains unknown, however, whether animals use innate or learned behaviour to discriminate food rewards. While many studies demonstrated that previous experience is a strong determinant of complex food choices such as diet mixing, the response to simple nutritional stimuli, such as sugar concentrations, is often believed to be innate. Results Here we show that previous experience determines the ability to track changes in sugar composition in same-aged individuals of a short-lived migratory songbird, the garden warbler (Sylvia borin. Although birds received identical foods for seven months prior to the experiment, wild-caught birds achieved higher sugar intake rates than hand-raised birds when confronted with alternative, differently coloured, novel food types. Hand-raised and wild birds did not differ in their initial colour selection or overall food intake, but wild birds were quicker to adjust food choice to varying sugar intake. Conclusion Over a period of at least seven months, broader previous experience translates into a higher plasticity of food choice leading to higher nutrient intake. Our results thus highlight the need to address previous long-term experience in foraging experiments. Furthermore, they show that hand-raised animals are often poor surrogates for testing the foraging behaviour of wild animals.

    Lecture content and practical laboratory classes are ideally complementary. However, the types of experiments that have led to our detailed understanding of sensory neuroscience are often not amenable to classroom experimentation as they require expensive equipment, time-consuming surgeries, specialized experimental techniques, and the use of animals. While sometimes feasible in small group teaching, these experiments are not suitable for large cohorts of students. Previous attempts to expose students to sensory neuroscience experiments include: the use of electrophysiology preparations in invertebrates, data-driven simulations that do not replicate the experience of conducting an experiment, or simply observing an experiment in a research laboratory. We developed an online simulation of a visual neuroscience experiment in which extracellular recordings are made from a motion sensitive neuron. Students have control over stimulation parameters (direction and contrast) and can see and hear the action potential responses to stimuli as they are presented. The simulation provides an intuitive way for students to gain insight into neurophysiology, including experimental design, data collection and data analysis. Our simulation allows large cohorts of students to cost-effectively "experience" the results of animal research without ethical concerns, to be exposed to realistic data variability, and to develop their understanding of how sensory neuroscience experiments are conducted.

    Objectives To determine whether students' previous pharmacy-related work experience was associated with their pharmacy school performance (academic and clinical). Methods The following measures of student academic performance were examined: pharmacy grade point average (GPA), scores on cumulative high-stakes examinations, and advanced pharmacy practice experience (APPE) grades. The quantity and type of pharmacy-related work experience each student performed prior to matriculation was solicited through a student survey instrument. Survey responses were correlated with academic measures, and demographic-based stratified analyses were conducted. Results No significant difference in academic or clinical performance between those students with prior pharmacy experience and those without was identified. Subanalyses by work setting, position type, and substantial pharmacy work experience did not reveal any association with student performance. A relationship was found, however, between age and work experience, ie, older students tended to have more work experience than younger students. Conclusions Prior pharmacy work experience did not affect students' overall academic or clinical performance in pharmacy school. The lack of significant findings may have been due to the inherent practice limitations of nonpharmacist positions, changes in pharmacy education, and the limitations of survey responses.

    Making a blood donation, especially for first-time donors, can be a stressful experience. These feelings of stress may inhibit donors from returning. This paper applies stress theory to this particular problem. The effects of a stress management intervention (the provision of music) and previous donor experience were examined in relation to pre- and post-donation mood, environmental appraisals and coping behaviour. Results indicated that the provision of music had detrimental effects on environmental appraisals for those who have donated up to two times previously, but beneficial effects for those who had donated three times before. These effects were, to an extent, moderated by coping processes but not perceived control. It is recommended that the provision of music is not used as a stress management technique in the context of blood donation.

    Establishing the architecture of gene regulatory networks (GRNs) relies on chromatin immunoprecipitation followed by massively parallel sequencing (ChIP-Seq) methods that provide genome-wide transcription factor binding sites (TFBSs). ChIP-Seq furnishes millions of short reads that, after alignment, describe the genome-wide binding sites of a particular TF. However, in all organisms investigated an average of 40% of reads fail to align to the corresponding genome, with some datasets having as much as 80% of reads failing to align. We describe here the provenance of previously unaligned reads in ChIP-Seq experiments from animals and plants. We show that a substantial portion corresponds to sequences of bacterial and metazoan origin, irrespective of the ChIP-Seq chromatin source. Unforeseen was the finding that 30%–40% of unaligned reads were actually alignable. To validate these observations, we investigated the characteristics of the previously unaligned reads corresponding to TAL1, a human TF involved in lineage specification of hemopoietic cells. We show that, while unmapped ChIP-Seq read datasets contain foreign DNA sequences, additional TFBSs can be identified from the previously unaligned ChIP-Seq reads. Our results indicate that the re-evaluation of previously unaligned reads from ChIP-Seq experiments will significantly contribute to TF target identification and determination of emerging properties of GRNs.

    Situational Judgement Tests (SJTs) are increasingly implemented in medical school admissions. In this paper, we investigate the effects of vocational interests, previous academic experience, gender and age on SJT performance. The SJT was part of the selection process for the Bachelor's degree programme in Medicine at University of Groningen, the Netherlands. All applicants for the academic year 2015-2016 were included and had to choose between learning communities Global Health (n = 126), Sustainable Care (n = 149), Intramural Care (n = 225), or Molecular Medicine (n = 116). This choice was used as a proxy for vocational interest. In addition, all graduate-entry applicants for academic year 2015-2016 (n = 213) were included to examine the effect of previous academic experience on performance. We used MANCOVA analyses with Bonferroni post hoc multiple comparisons tests for applicant performance on a six-scenario SJT. The MANCOVA analyses showed that for all scenarios, the independent variables were significantly related to performance (Pillai's Trace: 0.02-0.47, p performance on three scenarios (p performance on two scenarios (p performance, as was previous academic experience. Gender and age were related to performance on SJT scenarios in different settings. Especially the first effect might be helpful in selecting appropriate candidates for areas of health care in which more professionals are needed.

    2016-01-01

    In this paper, 11 narratives about former experiences in learning of mathematics written by nursing students are thematically analyzed. Most students had a positive relationship with the subject in primary school, when they found mathematics fun and were able to master the subject. For some, a change occurred in the transition to lower secondary school. The reasons for this change was found in the subject (increased difficulty), the teachers (movement of teachers, numerous substitute teachers), the class environment and size (many pupils, noise), and the student him- or herself (silent and anonymous pupil). This change was also found in the transition from lower to higher secondary school. By contrast, some students had experienced changes that were positive, and their mathematics teacher was a significant factor in this positive change. The paper emphasizes the importance of previous experiences in learning mathematics to nursing students when learning about drug calculation. Copyright © 2015. Published by Elsevier Ltd.

  19. Differences between previously married and never married 'gay' men: family background, childhood experiences and current attitudes.

    2004-01-01

    Despite a large body of literature on the development of sexual orientation, little is known about why some gay men have been (or remain) married to a woman. In the current study, a self-selected sample of 43 never married gay men ('never married') and 26 gay men who were married to a woman ('previously married') completed a self-report questionnaire. Hypotheses were based on five possible explanations for gay men's marriages: (a) differences in sexual orientation (i.e., bisexuality); (b) internalized homophobia; (c) religious intolerance; (d) confusion created because of childhood/adolescent sexual experiences; and/or (e) poor psychological adjustment. Previously married described their families' religious beliefs as more fundamentalist than never married. No differences were found between married' and never married' ratings of their sexual orientation and identity, and levels of homophobia and self-depreciation. Family adaptability and family cohesion and the degree to which respondents reported having experienced child maltreatment did not distinguish between previously married and never married. The results highlight how little is understood of the reasons why gay men marry, and the need to develop an adequate theoretical model.

    Understanding the proximate and ultimate sources of human cooperation is a fundamental issue in all behavioural sciences. In this paper, we review the experimental evidence on how people solve cooperation problems. Existing studies show without doubt that direct and indirect reciprocity are important determinants of successful cooperation. We also discuss the insights from a large literature on the role of peer punishment in sustaining cooperation. The experiments demonstrate that many people are 'strong reciprocators' who are willing to cooperate and punish others even if there are no gains from future cooperation or any other reputational gains. We document this in new one-shot experiments, which we conducted in four cities in Russia and Switzerland. Our cross-cultural approach allows us furthermore to investigate how the cultural background influences strong reciprocity. Our results show that culture has a strong influence on positive and in especially strong negative reciprocity. In particular, we find large cross-cultural differences in 'antisocial punishment' of pro-social cooperators. Further cross-cultural research and experiments involving different socio-demographic groups document that the antisocial punishment is much more widespread than previously assumed. Understanding antisocial punishment is an important task for future research because antisocial punishment is a strong inhibitor of cooperation.

  1. The relationship of previous training and experience of journal peer reviewers to subsequent review quality.

    Full Text Available BACKGROUND: Peer review is considered crucial to the selection and publication of quality science, but very little is known about the previous experiences and training that might identify high-quality peer reviewers. The reviewer selection processes of most journals, and thus the qualifications of their reviewers, are ill defined. More objective selection of peer reviewers might improve the journal peer review process and thus the quality of published science. METHODS AND FINDINGS: 306 experienced reviewers (71% of all those associated with a specialty journal completed a survey of past training and experiences postulated to improve peer review skills. Reviewers performed 2,856 reviews of 1,484 separate manuscripts during a four-year study period, all prospectively rated on a standardized quality scale by editors. Multivariable analysis revealed that most variables, including academic rank, formal training in critical appraisal or statistics, or status as principal investigator of a grant, failed to predict performance of higher-quality reviews. The only significant predictors of quality were working in a university-operated hospital versus other teaching environment and relative youth (under ten years of experience after finishing training. Being on an editorial board and doing formal grant (study section review were each predictors for only one of our two comparisons. However, the predictive power of all variables was weak. CONCLUSIONS: Our study confirms that there are no easily identifiable types of formal training or experience that predict reviewer performance. Skill in scientific peer review may be as ill defined and hard to impart as is "common sense." Without a better understanding of those skills, it seems unlikely journals and editors will be successful in systematically improving their selection of reviewers. This inability to predict performance makes it imperative that all but the smallest journals implement routine review ratings

    Full Text Available Background and Purpose: Bringing several opportunities for more effective and efficient IT governance and service exploitation, cloud computing is expected to impact the European and global economies significantly. Market data show that despite many advantages and promised benefits the adoption of cloud computing is not as fast and widespread as foreseen. This situation shows the need for further exploration of the potentials of cloud computing and its implementation on the market. The purpose of this research was to identify individual business model factors with the highest impact on cloud computing adoption. In addition, the aim was to identify the differences in opinion regarding the importance of business model factors on cloud computing adoption according to companies’ previous experiences with cloud computing services.

    Despite theoretical associations, there is a lack of empirical studies on the axiological basis of sexual liberalism-conservatism. Two studies demonstrated important associations between these constructs for young adults. In Study 1, participants were 353 undergraduate students with a mean age of 20.13 (SD = 1.84), who completed the Sexual Liberalism-Conservatism Scale and the Basic Values Survey. In Study 2, participants were 269 undergraduate students, with a mean age of 20.3 (SD = 1.82), who completed a social desirability scale in addition to Study 1 instruments. Results showed how values can predict sexual liberalism-conservatism after controlling for social desirability. Attitudes towards one's own sexual behavior were more conservative whereas attitudes towards other's sexual behavior were more liberal. Gender was not a significant predictor of sexual attitudes whereas previous sexual experience showed a significant association to this construct. In general, results corroborated previous findings, showing that participants with a tendency to present socially desirable answers also tended to present themselves as sexually conservative.

    A central function of the brain is to track the dynamic statistical regularities in the environment—such as what predicts what over time. How does this statistical learning process alter sensory and attentional processes? Drawing upon animal conditioning and predictive coding, we developed a learning procedure that revealed two distinct components through which prior learning-experience controls attention. During learning, a visual search task was used in which the target randomly appeared at one of several locations but always inside an encloser of a particular color—the learned color served to direct attention to the target location. During test, the color no longer predicted the target location. When the same search task was used in the subsequent test, we found that the learned color continued to attract attention despite the behavior being counterproductive for the task and despite the presence of a completely predictive cue. However, when tested with a flanker task that had minimal location uncertainty—the target was at the fixation surrounded by a distractor—participants were better at ignoring distractors in the learned color than other colors. Evidently, previously predictive cues capture attention in the same search task but can be better suppressed in a flanker task. These results demonstrate opposing components—capture and inhibition—in experience-driven attention, with their manifestations crucially dependent on task context. We conclude that associative learning enhances context-sensitive top-down modulation while reduces bottom-up sensory drive and facilitates suppression, supporting a learning-based predictive coding account.

    The aim of this study was to examine the effect of an enrichment programme in motor, technical and tactical basketball skills, when accounting for the age of youth sport specialisation. Seventy-six college students (age: M = 20.4, SD = 1.9) were allocated according to three different paths: (i) non-structured (n = 14), (ii) early specialisation (n = 34), and (iii) late specialisation (n = 28), according to information previously provided by the participants about the quantity and type of sporting activities performed throughout their sporting careers. Then, the participants of each path were randomly distributed across control and experimental groups. Variables under study included agility, technical skills circuit, as well as tactical actions performed in a 4-on-4 full-court basketball game. The results indicated improvements in the early and late specialisation paths namely in the experimental training groups. However, the late specialisation path revealed larger benefits, in contrast with the non-structured path, which showed less sensitivity to the enrichment programme, mostly sustained in physical literacy and differential learning. Higher improvements were observed in agility, and also in reducing the number of unsuccessful actions performed during the game. Overall, this study provided evidence of how early sports experiences affect basketball skill acquisition and contribute to adapt to new contexts with motor and technical-tactical challenges. In addition, a path supported by late specialisation might present several advantages in sport performance achievement.

    2015-01-01

    It has long been standard practice in radiation oncology to report internally when a patient’s treatment has not gone as planned and to report events to regulatory agencies when legally required. Most potential errors are caught early and never affect the patient. Quality assurance steps routinely prevent errors from reaching the patient, and these “near misses” are much more frequent than treatment errors. A growing number of radiation oncology facilities have implemented incident learning systems to report and analyze both errors and near misses. Using the term “incident learning” instead of “event reporting” emphasizes the need to use these experiences to change the practice and make future errors less likely and promote an educational, non-punitive environment. There are challenges in making such a system practical and effective. Speakers from institutions of different sizes and practice environments will share their experiences on how to make such a system work and what benefits their clinics have accrued. Questions that will be addressed include: How to create a system that is easy for front line staff to access How to motivate staff to report How to promote the system as positive and educational and not punitive or demeaning How to organize the team for reviewing and responding to reports How to prioritize which reports to discuss in depth How not to dismiss the rest How to identify underlying causes How to design corrective actions and implement change How to develop useful statistics and analysis tools How to coordinate a departmental system with a larger risk management system How to do this without a dedicated quality manager Some speakers’ experience is with in-house systems and some will share experience with the AAPM/ASTRO national Radiation Oncology Incident Learning System (RO-ILS). Reports intended to be of value nationally need to be comprehensible to outsiders; examples of useful reports will be shown. There will be ample time set

    Full Text Available ABSTRACT OBJECTIVE To estimate differential associations between the exposure to violence in the family of origin and victimization and perpetration of intimate partner violence in pregnancy. METHODS A nested case-control study was carried out within a cohort study with 1,120 pregnant women aged 18–49 years old, who were registered in the Family Health Strategy of the city of Recife, State of Pernambuco, Brazil, between 2005 and 2006. The cases were the 233 women who reported intimate partner violence in pregnancy and the controls were the 499 women who did not report it. Partner violence in pregnancy and previous experiences of violence committed by parents or other family members were assessed with a standardized questionnaire. Multivariate logistic regression analyses were modeled to identify differential associations between the exposure to violence in the family of origin and victimization and perpetration of intimate partner violence in pregnancy. RESULTS Having seen the mother suffer intimate partner violence was associated with physical violence in childhood (OR = 2.62; 95%CI 1.89–3.63 and in adolescence (OR = 1.47; 95%CI 1.01–2.13, sexual violence in childhood (OR = 3.28; 95%CI 1.68–6.38 and intimate partner violence during pregnancy (OR = 1.47; 95% CI 1.01 – 2.12. The intimate partner violence during pregnancy was frequent in women who reported more episodes of physical violence in childhood (OR = 2.08; 95%CI 1.43–3.02 and adolescence (OR = 1.63; 95%CI 1.07–2.47, who suffered sexual violence in childhood (OR = 3.92; 95%CI 1.86–8.27, and who perpetrated violence against the partner (OR = 8.67; 95%CI 4.57–16.45.

    To estimate differential associations between the exposure to violence in the family of origin and victimization and perpetration of intimate partner violence in pregnancy. A nested case-control study was carried out within a cohort study with 1,120 pregnant women aged 18-49 years old, who were registered in the Family Health Strategy of the city of Recife, State of Pernambuco, Brazil, between 2005 and 2006. The cases were the 233 women who reported intimate partner violence in pregnancy and the controls were the 499 women who did not report it. Partner violence in pregnancy and previous experiences of violence committed by parents or other family members were assessed with a standardized questionnaire. Multivariate logistic regression analyses were modeled to identify differential associations between the exposure to violence in the family of origin and victimization and perpetration of intimate partner violence in pregnancy. Having seen the mother suffer intimate partner violence was associated with physical violence in childhood (OR = 2.62; 95%CI 1.89-3.63) and in adolescence (OR = 1.47; 95%CI 1.01-2.13), sexual violence in childhood (OR = 3.28; 95%CI 1.68-6.38) and intimate partner violence during pregnancy (OR = 1.47; 95% CI 1.01 - 2.12). The intimate partner violence during pregnancy was frequent in women who reported more episodes of physical violence in childhood (OR = 2.08; 95%CI 1.43-3.02) and adolescence (OR = 1.63; 95%CI 1.07-2.47), who suffered sexual violence in childhood (OR = 3.92; 95%CI 1.86-8.27), and who perpetrated violence against the partner (OR = 8.67; 95%CI 4.57-16.45). Experiences of violence committed by parents or other family members emerge as strong risk factors for intimate partner violence in pregnancy. Identifying and understanding protective and risk factors for the emergence of intimate partner violence in pregnancy and its maintenance may help policymakers and health service managers to develop intervention strategies.

    Full Text Available PURPOSE: To evaluate the influence of the urologist's experience on the surgical results and complications of transurethral resection of the prostate (TURP. PATIENTS AND METHODS: Sixty-seven patients undergoing transurethral resection of the prostate without the use of a video camera were randomly allocated into three groups according to the urologist's experience: a urologist having done 25 transurethral resections of the prostate (Group I - 24 patients; a urologist having done 50 transurethral resections of the prostate (Group II - 24 patients; a senior urologist with vast transurethral resection of the prostate experience (Group III - 19 patients. The following were recorded: the weight of resected tissue, the duration of the resection procedure, the volume of irrigation used, the amount of irrigation absorbed and the hemoglobin and sodium levels in the serum during the procedure. RESULTS: There were no differences between the groups in the amount of irrigation fluid used per operation, the amount of irrigation fluid absorbed or hematocrit and hemoglobin variation during the procedure. The weight of resected tissue per minute was approximately four times higher in group III than in groups I and II. The mean absorbed irrigation fluid was similar between the groups, with no statistical difference between them (p=0.24. Four patients (6% presented with TUR syndrome, without a significant difference between the groups. CONCLUSION: The senior urologist was capable of resecting four times more tissue per time unit than the more inexperienced surgeons. Therefore, a surgeon's experience may be important to reduce the risk of secondary TURP due to recurring adenomas or adenomas that were incompletely resected. However, the incidence of complications was the same between the three groups.

    Cardiopulmonary resuscitation (CPR) is relatively novel branch of medical science, however first descriptions of mouth-to-mouth ventilation are to be found in the Bible and literature is full of descriptions of different resuscitation methods - from flagellation and ventilation with bellows through hanging the victims upside down and compressing the chest in order to stimulate ventilation to rectal fumigation with tobacco smoke. The modern history of CPR starts with Kouwenhoven et al. who in 1960 published a paper regarding heart massage through chest compressions. Shortly after that in 1961Peter Safar presented a paradigm promoting opening the airway, performing rescue breaths and chest compressions. First CPR guidelines were published in 1966. Since that time guidelines were modified and improved numerously by two leading world expert organizations ERC (European Resuscitation Council) and AHA (American Heart Association) and published in a new version every 5 years. Currently 2010 guidelines should be obliged. In this paper authors made an attempt to present history of development of resuscitation techniques and methods and assess the influence of previous lifesaving methods on nowadays technologies, equipment and guidelines which allow to help those women and men whose life is in danger due to sudden cardiac arrest. © 2015 MEDPRESS.

    Metastatic colorectal cancer (mCRC) is mainly a disease of elderly, however, geriatric population is underrepresented in clinical trials. Patient registries represent a tool to assess and follow treatment outcomes in this patient population. The aim of the study was with the help of the patients’ register to determine the safety and efficacy of bevacizumab plus chemotherapy in elderly patients who had previously untreated metastatic colorectal cancer. The registry of patients with mCRC was designed to prospectively evaluate the safety and efficacy of bevacizumab-containing chemotherapy as well as selection of patients in routine clinical practice. Patient baseline clinical characteristics, pre-specified bevacizumab-related adverse events, and efficacy data were collected, evaluated and compared according to the age categories. Between January 2008 and December 2010, 210 patients with mCRC (median age 63, male 61.4%) started bevacizumab-containing therapy in the 1 st line setting. Majority of the 210 patients received irinotecan-based chemotherapy (68%) as 1 st line treatment and 105 patients (50%) received bevacizumab maintenance therapy. Elderly (≥ 70 years) patients presented 22.9% of all patients and they had worse performance status (PS 1/2, 62.4%) than patients in < 70 years group (PS 1/2, 35.8%). Difference in disease control rate was mainly due to inability to assess response in elderly group (64.6% in elderly and 77.8% in < 70 years group, p = 0.066). The median progression free survival was 10.2 (95% CI, 6.7–16.2) and 11.3 (95% CI, 10.2–12.6) months in elderly and < 70 years group, respectively (p = 0.58). The median overall survival was 18.5 (95% CI, 12.4–28.9) and 27.4 (95% CI, 22.7–31.9) months for elderly and < 70 years group, respectively (p = 0.03). Three-year survival rate was 26% and 37.6% in elderly vs. < 70 years group (p = 0.03). Overall rates of bevacizumab-related adverse events were similar in both groups: proteinuria 21

    To examine the relationship between baseline emotional intelligence and prior caring experience with completion of pre-registration nurse and midwifery education. Selection and retention of nursing students is a global challenge. Emotional intelligence is well-conceptualized, measurable and an intuitive prerequisite to nursing values and so might be a useful selection criterion. Previous caring experience may also be associated with successful completion of nurse training. Prospective longitudinal study. Self-report trait and ability emotional intelligence scores were obtained from 876 student nurses from two Scottish Universities before they began training in 2013. Data on previous caring experience were recorded. Relationships between these metrics and successful completion of the course were calculated in SPSS version 23. Nurses completing their programme scored significantly higher on trait emotional intelligence than those that did not complete their programme. Nurses completing their programme also scored significantly higher on social connection scores than those that did not. There was no relationship between "ability" emotional intelligence and completion. Previous caring experience was not statistically significantly related to completion. Students with higher baseline trait emotional intelligence scores were statistically more likely to complete training than those with lower scores. This relationship also held using "Social connection" scores. At best, previous caring experience made no difference to students' chances of completing training. Caution is urged when interpreting these results because the headline findings mask considerable heterogeneity. Neither previous caring experience or global emotional intelligence measures should be used in isolation to recruit nurses. © 2017 The Authors.

    Changing lifestyle is challenging and difficult. The Norwegian Directorate of Health recommends that all municipalities establish Healthy Life Centres targeted to people with lifestyle issues. Little is known about the background, experiences and reflections of participants. More information is needed about participants to shape effective lifestyle interventions with lasting effect. This study explores how participants in a lifestyle intervention programme describe previous life experiences in relation to changing lifestyle. Semi-structured qualitative in-depth interviews were performed with 23 participants (16 women and 7 men) aged 18 - 70 years. The data were analysed using systematic text condensation searching for issues describing participants' responses, and looking for the essence, aiming to share the basis of life-world experiences as valid knowledge. Participants identified two main themes: being stuck in old habits, and being burdened with emotional baggage from their previous negative experiences. Participants expressed a wish to change their lifestyles, but were unable to act in accordance with the health knowledge they possessed. Previous experiences with lifestyle change kept them from initiating attempts without professional assistance. Participants also described being burdened by an emotional baggage with problems from childhood and/or with family, work and social life issues. Respondents said that they felt that emotional baggage was an important explanation for why they were stuck in old habits and that conversely, being stuck in old habits added load to their already emotional baggage and made it heavier. Behavioural change can be hard to perform as psychological distress from life baggage can influence the ability to change. The study participants' experience of being stuck in old habits and having substantial emotional baggage raises questions as to whether or not Healthy Life Centres are able to help participants who need to make a lifestyle

    We determine the relationship between premature loss of primary teeth and oral hygiene, consumption of soft drinks, dental care and previous caries experience. This study focused on 833 Mexican schoolchildren aged 6-7. We performed an oral examination to determine caries experience and the simplified oral hygiene index. The dependent variable was the prevalence of at least one missing tooth (or indicated for extraction) of the primary dentition; this variable was coded as 0 = no loss of teeth and 1 = at least one lost primary tooth. The prevalence of at least one missing tooth was 24.7% (n = 206) (95% CI = 21.8-27.7). The variables that were associated with the prevalence of tooth loss (p oral hygiene (OR = 3.24), a lower frequency of brushing (OR = 1.60), an increased consumption of soda (OR = 1.89) and use of dental care (curative: OR = 2.83, preventive: OR = 1.93). This study suggests that the premature loss of teeth in the primary dentition is associated with oral hygiene, consumption of soft drinks, dental care and previous caries experience in Mexican schoolchildren. These data provide relevant information for the design of preventive dentistry programs.

    Although it is the only curative treatment for polycystic liver disease (PLD), orthotopic liver transplantation (OLT) has been reserved for severely symptomatic, malnourished, or refractory patients who are not candidates for palliative disease-directed interventions (DDI). Data on the effect of previous DDIs on post-transplant morbidity and mortality are scarce. We analyzed the outcomes after OLT for PLD recipients, and determined the effects of previous palliative surgical intervention on post-transplantation morbidity and mortality. We performed a retrospective analysis of factors affecting perioperative outcomes after OLT for PLD between 1992 and 2013, including comparisons of recipients with previous major open DDIs (Open DDI, n = 12) with recipients with minimally invasive or no previous DDIs (minimal DDI, n = 16). Over the 20-year period, 28 recipients underwent OLT for PLD, with overall 30-day, 1-, and 5-year graft and patient survivals of 96%, 89%, 75%, and 96%, 93%, 79%, respectively. Compared with the minimal DDI group, open DDI recipients accounted for all 5 deaths, had inferior 90-day and 1- and 5-year survivals (83%, 83%, and 48% vs 100%, 100%, 100%; p = 0.009), and greater intraoperative (42% vs 0%; p = 0.003), total (58% vs 19%; p = 0.031), and Clavien grade IV or greater (50% vs 6%; p = 0.007) postoperative complications, more unplanned reoperations (50% vs 13%; p = 0.003), and longer total hospital (27 days vs 17 days; p = 0.035) and ICU (10 days vs 4 days; p = 0.045) stays. In one of the largest single-institution experiences of OLT for PLD, we report excellent long-term graft and patient survival. Previous open DDIs are associated with increased risks of perioperative morbidity and mortality. Improved identification of PLD patients bound for OLT may mitigate perioperative complications and potentially improve post-transplantation outcomes. Copyright © 2014 American College of Surgeons.

  11. Does Previous Experience of Floods Stimulate the Adoption of Coping Strategies? Evidence from Cross Sectional Surveys in Nigeria and Tanzania

    Full Text Available In sub-Saharan Africa, hydro-meteorological related disasters, such as floods, account for the majority of the total number of natural disasters. Over the past century, floods have affected 38 million people, claimed several lives and caused substantial economic losses in the region. The goal of this paper is to examine how personality disposition, social network, and socio-demographic factors mitigate the complex relationship between stressful life experiences of floods and ocean surges and the adoption of coping strategies among coastal communities in Nigeria and Tanzania. Generalized linear models (GLM were fitted to cross-sectional survey data on 1003 and 1253 individuals in three contiguous coastal areas in Nigeria and Tanzania, respectively. Marked differences in the type of coping strategies were observed across the two countries. In Tanzania, the zero-order relationships between adoption of coping strategies and age, employment and income disappeared at the multivariate level. Only experience of floods in the past year and social network resources were significant predictors of participants’ adoption of coping strategies, unlike in Nigeria, where a plethora of factors such as experience of ocean surges in the past one year, personality disposition, age, education, experience of flood in the past one year, ethnicity, income, housing quality and employment status were still statistically significant at the multivariate level. Our findings suggest that influence of previous experience on adoption of coping strategies is spatially ubiquitous. Consequently, context-specific policies aimed at encouraging the adoption of flood-related coping strategies in vulnerable locations should be designed based on local needs and orientation.

  12. The Impact of Previous Action on Bargaining—An Experiment on the Emergence of Preferences for Fairness Norms

    Directory of Open Access Journals (Sweden)

    Thomas Neumann

    2017-08-01

    Full Text Available The communication of participants to identify an acceptable bargaining outcome in the Nash bargaining game is all about fairness norms. Participants introduce fairness norms which yield a better outcome for themselves in order to convince the other participant of their bargaining proposal. Typically, these fairness norms are in line with theoretical predictions, which support a wide variety of different but fair outcomes the participants can choose from. In this experiment, we play two treatments of the Nash bargaining game: in one treatment, the participants play a dictator game prior to bargaining, and in the other treatment they do not. We find that participants who have not played the dictator game intensively discuss the outcome of the game and come to solutions closer to the equal split of the pie the longer they chat. This effect vanishes as soon as the participants have previous experience from a dictator game: instead of chatting, they establish the fairness norm introduced in the dictator game. Remarkably, if the dictator is unfair in the dictator game, he also gets a higher share of the pie in the Nash bargaining game.

    Full Text Available L'articolo riflette sulle relazioni tra comunicazione, violenza e gioco, nel tentativo di rintracciare tra loro convergenze, affinità e contrasti. Le nostre relazioni, infatti, ci immettono inerzialmente in dilemmi e paradossi di così alta complessità da rendere spesso inadeguati gli strumenti 'logici' ed 'analitici': dal che può derivare un senso di impotenza, rabbia, paralisi, ma anche un desiderio potente di controllo e di soluzione degli eventi. Entrambe queste strade ci conducono dentro le false alternative della violenza. La cultura del gioco, invece, ci propone (attraverso le sue pratiche, ma anche negli scritti teorici di Freud, Winnicott, Bateson, qui riassunti e rivisitati una modalità più creativa e nonviolenta, più prossima ad un' ecologia della mente e ad un'estetica delle emozioni.

    Cuando publiqué mi trabajo titulado “Inteligencia Artificial y Neurología” en la Revista MEDICINA en cuatro ejemplares Nos. 14, 15, 16, 17, Años 1986-1987, expuse exhaustivamente la contribución científica contemporánea de las Neuro-ciencias y experimenté la ingenua ilusión (frecuente ocurrencia en el ser humano de participar, así fuese muy lejanamente, en el optimismo de los científicos japoneses quienes ofrecían obtener en el decurso de pocos años inteligencia artificial equiparable con la inteligencia humana. Infortunadamente no sucedió así, no podía ser así, lo que nunca quiere decir que de mi parte se ignoren o se desconozcan los sensacionales logros que esos mismos científicos han venido consiguiendo.

    Ahora me encuentro entusiasmado en el desarrollo de otro tema de características similares, lo cual me induce a comentarlo así sea someramente en su trayectoria.

    Se trata de la teoría computacional de la mente, interesantísimo rubro expuesto prolijamente por Steven Pinker del Instituto Tecnológico de Massachussets en el libro del cual es autor, “best seller” de 660 páginas titulado “How the Mind Works”, publicado el año pasado con 800 referencias de bibliografía.

    Su cuidadosa lectura con mis múltiples fieles transcripciones a más de mi información personal mediante Internet, constituyen el bagage intelectual y el soporte científico que me han impulsado a escribir este somero comentario sobre tan trascendente tema, con destino a MEDICINA.

    La Teoría Computacional de la Mente tiene su origen en las ideas geniales del matemático norteamericano Alan Turing quien demostró que una máquina binaria podía ser programada para realizar cualquier tarea algorítmica, lo cual fue complementado en el mismo año de 1937 por Claude Shannon del MIT con la noción de integración de circuitos en los rieles eléctricos que integran el sistema binario de almacenamiento de informaci

  18. Influence of Previous Crop on Durum Wheat Yield and Yield Stability in a Long-term Experiment

    Full Text Available Long-term experiments are leading indicators of sustainability and serve as an early warning system to detect problems that may compromise future productivity. So the stability of yield is an important parameter to be considered when judging the value of a cropping system relative to others. In a long-term rotation experiment set up in 1972 the influence of different crop sequences on the yields and on yield stability of durum wheat (Triticum durum Desf. was studied. The complete field experiment is a split-split plot in a randomized complete block design with two replications; the whole experiment considers three crop sequences: 1 three-year crop rotation: sugar-beet, wheat + catch crop, wheat; 2 one-year crop rotation: wheat + catch crop; 3 wheat continuous crop; the split treatments are two different crop residue managements; the split-split plot treatments are 18 different fertilization formulas. Each phase of every crop rotation occurred every year. In this paper only one crop residue management and only one fertilization treatment have been analized. Wheat crops in different rotations are coded as follows: F1: wheat after sugar-beet in three-year crop rotation; F2: wheat after wheat in three-year crop rotation; Fc+i: wheat in wheat + catch crop rotation; Fc: continuous wheat. The following two variables were analysed: grain yield and hectolitre weight. Repeated measures analyses of variance and stability analyses have been perfomed for the two variables. The stability analysis was conducted using: three variance methods, namely the coefficient of variability of Francis and Kannenberg, the ecovalence index of Wricke and the stability variance index of Shukla; the regression method of Eberhart and Russell; a method, proposed by Piepho, that computes the probability of one system outperforming another system. It has turned out that each of the stability methods used has enriched of information the simple variance analysis. The Piepho

    Before licensing, ipilimumab was first made available to previously treated advanced melanoma patients through an expanded access programme (EAP) across Europe. We interrogated data from UK EAP patients to inform future clinical practice. Clinicians registered in the UK EAP provided anonymized patient data using a prespecified variable fields datasheet. Data collected were baseline patient characteristics, treatment delivered, toxicity, response, progression-free survival and overall survival (OS). Data were received for 193 previously treated metastatic melanoma patients, whose primary sites were cutaneous (82%), uveal (8%), mucosal (2%), acral (3%) or unknown (5%). At baseline, 88% of patients had a performance status (PS) of 0-1 and 20% had brain metastases. Of the patients, 53% received all four planned cycles of ipilimumab; the most common reason for stopping early was disease progression, including death from melanoma. Toxicity was recorded for 171 patients, 30% of whom experienced an adverse event of grade 3 or higher, the most common being diarrhoea (13%) and fatigue (9%). At a median follow-up of 23 months, the median progression-free survival and OS were 2.8 and 6.1 months, respectively; the 1-year and 2-year OS rates were 31 and 14.8%, respectively. The 2-year OS was significantly lower for patients with poorer PS (P<0.0001), low albumin concentrations (P<0.0001), the presence of brain metastases (P=0.007) and lactate dehydrogenase levels more than two times the upper limit of normal (P<0.0001) at baseline. These baseline characteristics are negative predictors of benefit from ipilimumab and should be taken into consideration before prescription.

    Physical activity performed at moderate intensity is associated with reduced risk of mortality, cardiovascular disease, hypertension, and some types of cancers. However, vigorous physical activity during participation in college athletics may increase the risk of injury, which might limit future physical activity levels. To evaluate differences in current physical fitness levels between former Division I athletes and noncollegiate athletes. Cross-sectional study. Level 3. The sample was recruited from a large midwestern university alumni database and consisted of 2 cohorts: (1) former Division I athletes (n = 100; mean age, 53.1 ± 7.4 years) and (2) nonathletes who were active in college (n = 100; age, 51.4 ± 7.3 years). Individuals answered a demographics questionnaire and completed a physical fitness assessment consisting of 7 measures: percent body fat, 1-mile walk, sit-to-stand test, push-up, half sit-up test, sit and reach test, and back scratch test. Performance was significantly worse for former Division I athletes compared with nonathletes for percent body fat (mean difference, 7.58%; F (1, 198) = 59.91; P sit-to-stand test (mean difference, 4.3 repetitions; F (1, 198) = 6.59; P = 0.01), and push-up test (mean difference, 8.9 repetitions; F (1, 198) = 7.35; P = 0.01). Former Division I athletes may be limited because of previous injury, inhibiting their ability to stay active later in life. It is imperative that clinicians, coaches, and strength and conditioning specialists understand the possible future repercussions from competing at the Division I level.

    Full Text Available Background & aim:  High-risk pregnancies increase the risk of Intensive Care Unit (ICU and Neonatal Intensive Care Unit (NICU admission in mothers and their newborns. In this study, we aimed to identify the association between the recurrence of high-risk pregnancy and mothers’ previous experience of having an infant admitted to NICU. Methods:We performed a cohort, retrospective study to compare subsequent pregnancy outcomes among 232 control subjects and 200 female cases with a previous experience of having a newborn requiring NICU admission due to intrauterine growth retardation, preeclampsia, preterm birth, premature rupture of membranes, and asphyxia. The information about the prevalence of subsequent high-risk pregnancies was gathered via phone calls. Results: As the results indicated, heparin, progesterone, and aspirin were more frequently administered in the case group during subsequent pregnancies, compared to the control group (P

    Patients express high anxiety preoperatively, because of fears related to anesthesia and its implications. The purpose of this survey was to gain insight into these fears and to study whether they are affected by patients' sex, age, education, or previous experience of anesthesia. Questionnaires with fixed questions were distributed to consenting, consecutive surgical patients before the pre-anesthetic visit. The questionnaires included patients' demographics and questions related to their fears about anesthesia. Four-hundred questionnaires were collected and analyzed. Eighty-one percent of patients experience preoperative anxiety. The main sources of their anxiety were fear of postoperative pain (84 %), of not waking up after surgery (64.8 %), of being nauseous or vomiting (60.2 %), and of drains and needles (59.5 %). Patients are less concerned about being paralyzed because of anesthesia (33.5 %) or of revealing personal issues (18.8 %). Gender seems to affect patients fears, with women being more afraid (85.3 vs. 75.6 % of men, p = 0.014). The effects of patients' age, level of education, and previous experience of anesthesia are minor, except for individual questions. Sixty-three percent of our patients (mostly women 67.4 vs. 57.4 % of men, p = 0.039) talk about these fears with their relatives, although a vast majority of 95.5 % would prefer to talk with the anesthesiologist and be reassured by him. All patients, mostly women, express fears about anesthesia; this fear leads to preoperative anxiety. Slight differences are observed for some individual questions among patients of different sex, education level, and previous experience of anesthesia.

    Breastfeeding confers important health benefits to both infants and their mothers, but rates are low in the United Kingdom and other developed countries despite widespread promotion. This study examined the relationships between personal and vicarious experience of infant feeding, self-efficacy, the theory of planned behaviour variables of attitudes and subjective norm, and the likelihood of breastfeeding at 6-8 weeks post-natally. A prospective questionnaire study of both first-time mothers (n = 77) and experienced breastfeeders (n = 72) recruited at an antenatal clinic in South East England. Participants completed a questionnaire at 32 weeks pregnant assessing personal and vicarious experience of infant feeding (breastfeeding, formula-feeding, and maternal grandmother's experience of breastfeeding), perceived control, self-efficacy, intentions, attitudes (to breastfeeding and formula-feeding), and subjective norm. Infant feeding behaviour was recorded at 6-8 weeks post-natally. Multiple linear regression modelled the influence of vicarious experience on attitudes, subjective norm, and self-efficacy (but not perceived control) and modelled the influence of attitude, subjective norm, self-efficacy, and past experience on intentions to breastfeed. Logistic regression modelled the likelihood of breastfeeding at 6-8 weeks. Previous experience (particularly personal experience of breastfeeding) explained a significant amount of variance in attitudes, subjective norm, and self-efficacy. Intentions to breastfeed were predicted by subjective norm and attitude to formula-feeding and, in experienced mothers, self-efficacy. Breastfeeding at 6 weeks was predicted by intentions and vicarious experience of formula-feeding. Vicarious experience, particularly of formula-feeding, has been shown to influence the behaviour of first-time and experienced mothers both directly and indirectly via attitudes and subjective norm.

    Full Text Available CONTEXTO: O avanço no entendimento da mente e sua relação com o cérebro tem sido prejudicado por equívocos filosóficos e metodológicos. OBJETIVO: Discutir brevemente e propor diretrizes epistemológicas e metodológicas para uma frutífera investigação da relação mente-cérebro. RESULTADOS: A relação mente-corpo ainda é um problema em aberto, não havendo evidências conclusivas de que a mente seja apenas um produto da atividade cerebral. Na exploração da mente, deve-se evitar a aceitação ou rejeição prematura de teorias, buscando não apenas evidências confirmatórias, mas também as falseadoras de uma teoria. Deve-se ampliar e diversificar a base empírica, buscando especialmente experiências humanas não usuais, tais como as chamadas experiências anômalas ou espirituais. A observação de fenômenos anômalos que não se encaixavam nos paradigmas estabelecidos foi essencial em revoluções científicas prévias. Tanto dados quantitativos quanto qualitativos devem ser valorizados. Para explicar a mente e suas múltiplas manifestações, é essencial haver abertura e rigor para criar, desenvolver e testar alternativas teóricas. Candidatos a paradigma de base tanto materialista quanto não materialista devem ter oportunidade de ser apresentados, aprimorados e testados. CONCLUSÃO: A ampliação e a diversificação da base empírica aliada a uma postura epistemológica e metodológica mais adequada são essenciais para o avanço da compreensão da relação mente-cérebro.

This paper evaluates how research efforts have applied LCA and RA together for NM, particularly reflecting on previous experiences with applying these methods to chemicals. Through a literature review and a separate analysis of research focused on applying LCA and RA together for NM, it appears that current research efforts have taken into account some key “lessons learned” from previous experience with chemicals while many key challenges remain for practically applying these methods to NM. We identified two main approaches for using these methods together for NM: “LC-based RA” (traditional RA applied in a life-cycle perspective) and “RA-complemented LCA” (conventional LCA supplemented by RA in specific life-cycle steps). Hence, the latter is the only identified approach which genuinely combines LC- and RA-based methods for NM-risk research efforts to date as the former is rather a continuation of normal RA according to standard assessment procedures (e.g., REACH). Both these approaches along with recommendations for using LCA and RA together for NM are similar to those made previously for chemicals, and thus, there does not appear to be much progress made specific for NM. We have identified one issue in particular that may be specific for NM when applying LCA and RA at this time: the need to establish proper dose metrics within both methods.

    To remedy the relative neglect of the contribution of Sabina Spielrein to psychoanalysis this article details her early life, psychiatric hospitalization, analysis by Jung, love affair with him, extracts from her diary, correspondence with Jung and Freud, and published writing. Together this material highlights Spielrein's pioneering insights regarding the involvement of what Bion subsequently called "at-one-ment" in (a) the transformations effected by the transference-countertransference of patient and analyst in analysis, (b) art, (c) symbolism as universalizing inspiration or defence, (d) the death instinct, (e) the subconscious as semiotic mediator between what is conscious and unconscious, and (f) children's early language acquisition.

    Full Text Available Resumo Tendo em vista as interfaces entre teoria da mente e linguagem e os benefícios da leitura mediada para o desenvolvimento sociocognitivo infantil, apresenta-se a vertente qualitativa de um estudo mais amplo sobre teoria da mente, que, de forma complementar, investigou as experiências vivenciadas por pré-escolares em relação à atividade leitora no contexto familiar e escolar. Participaram da pesquisa 178 crianças e 17 docentes de escolas públicas e privadas de educação infantil. As crianças responderam a um questionário que buscou avaliar o contexto familiar das atividades diárias de leitura; já as professoras foram entrevistadas para avaliar as concepções e práticas sobre as atividades leitoras em sala de aula, sendo os relatos submetidos à análise de conteúdo. Os resultados indicam que os contextos de leitura tanto familiar quanto escolar são potencialmente favoráveis ao desenvolvimento sociocognitivo e tendem a contribuir para o aprimoramento da compreensão infantil dos estados mentais.

    Full Text Available Estimates of the prevalence and causes of visual impairment in South Africa are reviewed against the existing services and limitations in the country. The magnitude1 of visual impair-ment  and  the  projected  increase  worldwide over the coming decades have been recognized as having potentially far-reaching social, eco-nomic and quality of life implications for not only the affected individuals but also for their families and communities. Two-thirds or more of all blindness is avoidable, in that the causes are  preventable  or  treatable.2,  3  Early  detec-tion, prevention and management programs are needed to reduce the impact of visual impair-ment. Approximately 80% of the South African population is indigent, relying on public hospi-tals and clinics and the remaining 20% of the population has access to private health care.4 As the majority of eye care professionals are in private practice, access to eye care services are available to only a minority of the population. This paper reviews the current services in South Africa and the challenges that lie ahead.

    Full Text Available Hasta ahora, el acceso a otras mentes presuponía las expresiones y narraciones de los individuos. En la actualidad, se han desarrollado varios métodos que pueden medir los estados cerebrales relevantes para valorar las facultades mentales sin que se manifieste en 1ª persona habla o comportamiento externo alguno. La resonancia magnética funcional y el condicionamiento de huella se emplean fuera del ámbito clínico para acceder a la conciencia subjetiva; se utilizan clínicamente para identificar patrones de actividad en el cerebro que sugieran la presencia de conciencia en personas que sufren trastornos graves de conciencia y métodos para comunicarse cerebralmente con pacientes con incapacidad motora para comunicarse. En este capítulo, examinamos las posibilidades y los límites del acceso a otras mentes mediante interfaces cerebro-máquina. Exponemos que estas técnicas auguran importantes avances médicos y abren nuevas perspectivas de comunicación y para entender la conciencia, sin embargo, también plantean preocupaciones éticas, en especial el uso incorrecto como consecuencia de las expectativas creadas y las malas interpretaciones.

En estos últimos 100 años, se ha generado gran parte del cuerpo de conocimientos que sustenta nuestra visión general del sistema nervioso. Numerosas características bioquímicas, fisiológicas, farmacológicas y estructurales del cerebro han sido descritas, primero en invertebrados y luego en vertebrados. En los últimos años, esfuerzos importantes han sido destinados también a definir las bases de las funciones de percepción, emoción, memoria, atención y cognición. Por último, tanto los métodos experimentales como la observación de individuos (a menudo pacientes con lesiones definidas nos han permitido asociar ciertas funciones a regiones neuroanatómicas específicas.

    This study aimed to evaluate rates of success and perinatal complications of labour induction using an intracervical Foley catheter among women with a previous Caesarean delivery at a tertiary centre in Oman. This retrospective cohort study included 68 pregnant women with a history of a previous Caesarean section who were admitted for induction via Foley catheter between January 2011 and December 2013 to the Sultan Qaboos University Hospital, Muscat, Oman. Patient data were collected from electronic and delivery ward records. Most women were 25-35 years old (76.5%) and 20 women had had one previous vaginal delivery (29.4%). The most common indication for induction of labour was intrauterine growth restriction with oligohydramnios (27.9%). Most women delivered after 40 gestational weeks (48.5%) and there were no neonatal admissions or complications. The majority experienced no complications during the induction period (85.3%), although a few had vaginal bleeding (5.9%), intrapartum fever (4.4%), rupture of the membranes (2.9%) and cord prolapse shortly after insertion of the Foley catheter (1.5%). However, no cases of uterine rupture or scar dehiscence were noted. Overall, the success rate of vaginal birth after a previous Caesarean delivery was 69.1%, with the remaining patients undergoing an emergency Caesarean section (30.9%). The use of a Foley catheter in the induction of labour in women with a previous Caesarean delivery appears a safe option with a good success rate and few maternal and fetal complications.

    2015-07-01

    Full Text Available Este artículo se centra en una inquietud fundamental: pensar la filosofía musical en Clément Rosset. Para comprender las premisas fundamentales que guían al autor, debemos tener en cuenta su lectura de Schopenhauer, Nietzsche y Jankélévitch, ya que es con estos filósofos-músicos que Rosset elabora su comprensión de la música. Por ello, si es posible reconocer una línea de pensamiento que ligue la filosofía y la música desde el siglo XIX, es necesario a la vez preguntarnos si con Rosset existe una verdadera modificación, o si su escritura se dedica a repetir únicamente los enunciados ya planteados por Nietzsche y Jankélévitch. Este debate es pertinente, ya que Rosset es considerado en Francia como el heredero de una nueva filosofía musical, sin embargo su aporte no aparece muy claro, lo cual nos hace pensar que es la única alternativa que queda frente a la escasez filosófica que sufre el ambiente intelectual parisino. Queremos ver, por tanto, si las reflexiones de Rosset llevan la filosofía musical hacia nuevos territorios o si estamos frente a un silencio que se impone por la incapacidad de filosofar.

    Atrial fibrillation is the main reason for oral anticoagulation in our community. New oral anticoagulants (NOACs) overcome the disadvantages of vitamin K antagonists (VKAs), although there are scarce data on its use in our community. The aim of our study was to assess the use of NOACs and anticoagulation control using VKA as measured by the time within the therapeutic range (TTR) in an actual clinical scenario. A retrospective cohort analysis was conducted of 816 patients admitted to cardiology over a period of 3 years, with a diagnosis of atrial fibrillation and anticoagulant treatment at discharge. We assessed the percentage of patients prescribed NOACs and the TTR with VKA. We compared safety and efficacy events during the 15-month follow-up among the patients prescribed NOAC, those prescribed VKA with a good TTR and those with a poor TTR. The percentage of patients prescribed NOAC was 7.6%. Serial INR measurements found that 71.3% of patients had a poor TTR. Although the groups were not comparable, a higher incidence of the combined event was observed in those treated with VKA and a poor TTR compared with those prescribed NOAC (p=.01). For patients with a previous hospitalization in cardiology in a tertiary hospital and a diagnosis of atrial fibrillation, the rate of NOAC prescription is low, and the TTR with VKA was poor.

    Full Text Available An investigation of factors that facilitate the utilization of research evidence among faculty, staff, and volunteers in the 4-H Youth Development Program is presented in this paper. Participants (N= 368; 86 4-H faculty, 153 staff, and 129 volunteers represented 35 states; structural equation modeling was utilized in the analyses. Results of the path analysis explained 56% of variance in research utilization and 28% in research utilization self-efficacy. Among the factors impacting research utilization, self-efficacy played the most important role. In turn, self-efficacy for research utilization was positively influenced by participants’ learning goal orientation, frequency of 4-H training during the last 12 months, education in research-related areas, and investigative career interests. In addition, 4-H staff who were exposed to research at higher levels reported higher research utilization self-efficacy. The findings reinforce the importance of fostering research utilization self-efficacy among 4-H faculty, staff, and volunteers. Among the suggestions presented are regular 4-H training opportunities and on-going exposure to program evaluation and program improvement experiences.

  14. Influence of previous experience on the preference, food utilization and performance of Ascia monuste orseis wild larvae (Godart) (Lepidoptera: Pieridae) for three different hosts.

    The exhaustion of food resources which occurs during the ontogenetic growth of Ascia monuste orseis (Godart) results in the dispersion of older larvae to nearby plants in order to complete their development, which might expose these animals to the nutritional variation of the hosts found. This study aimed to verify whether the food ingested in the beginning of the development influences the larvae host preference and whether the shift to a new host can affect the digestion and performance of A. monuste orseis, using two natural hosts: kale (Brassica oleracea var. acephala) and rocket (Eruca sativa), or kale and cabbage (B. oleracea var. capitata). Larvae were reared throughout their larval development on a single host or on two different hosts. When a host change was tested, larvae were reared for four instars on a host, and offered the other host plant in the fifth instar. Development time, percentage of pupation and emergence, pupal weight, fecundity and digestive indices were evaluated. The change in feeding preference for kale and for rocket in the fourth instar, when those were the original hosts, respectively, shows that prior experience plays a major role in food preference of immature A. monuste orseis. The shift can be beneficial for larval development, depending on the order of the hosts; in general, larvae fed on kale at the end of the development showed better performance. Our results presented strong evidence of a considerable phenotypic plasticity in A. monuste orseis for host preferences.

  15. Operações sociais da mente = Social operations of mind

    Directory of Open Access Journals (Sweden)

    Leclerc, André

    2010-01-01

    Full Text Available Thomas Reid introduziu a noção de operação social da mente na teoria da mente e da linguagem. Seu amigo James Gregory desenvolveu essa noção no contexto da Gramática Universal clássica, particularmente na teoria geral dos modos verbais. A gramática filosófica clássica, antes de Reid e Gregory, pressupõe inter alia que a mente é “autocontida” (self-contained; em outras palavras, que os conteúdos e as operações mentais independem do ambiente natural e social. Algumas dessas operações têm uma estrutura em modus/ dictum que corresponde, grosso modo, à distinção atual entre modo psicológico e conteúdo mental conceitual, análoga à distinção entre força ilocucionária e conteúdo proposicional e que se reflete parcialmente no sistema de modos verbais nas línguas naturais. A famosa Gramática de Port-Royal já indicava uma limitação importante desse modelo de mente autocontida: “On ne se commande pas proprement à soimême”, escrevem Arnauld & Lancelot (“Não se ordena propriamente a si mesmo”. Defenderei que Reid percebeu que o individualismo não permite capturar os aspectos sociais da linguagem e, por isso, viu a necessidade de apresentar uma concepção de mente diferente, antiindividualista. A noção de operação social da mente é a peça fundamental da reforma empreendida por Reid em filosofia da mente. Ademais, ele e Gregory defenderam que as linguagens se formaram particularmente para expressar esses aspectos sociais da linguagem e da mente

    Except for dementia and depression, little is known about common mental disorders in elderly people. To estimate current, 12-month and lifetime prevalence rates of mental disorders in different European and associated countries using a standardised diagnostic interview adapted to measure the cognitive needs of elderly people. The MentDis_ICF65+ study is based on an age-stratified, random sample of 3142 older men and women (65-84 years) living in selected catchment community areas of participating countries. One in two individuals had experienced a mental disorder in their lifetime, one in three within the past year and nearly one in four currently had a mental disorder. The most prevalent disorders were anxiety disorders, followed by affective and substance-related disorders. Compared with previous studies we found substantially higher prevalence rates for most mental disorders. These findings underscore the need for improving diagnostic assessments adapted to the cognitive capacity of elderly people. There is a need to raise awareness of psychosocial problems in elderly people and to deliver high-quality mental health services to these individuals. © The Royal College of Psychiatrists 2017.

    Full Text Available Following the abdominal surgery, extensive adhesions often occur and they can cause difficulties during laparoscopic operations. However, previous laparotomy is not considered to be a contraindication for laparoscopy. The aim of this study is to present that an insertion of Veres needle in the region of umbilicus is a safe method for creating a pneumoperitoneum for laparoscopic operations after previous laparotomy. In the last three years, we have performed 144 laparoscopic operations in patients that previously underwent one or two laparotomies. Pathology of digestive system, genital organs, Cesarean Section or abdominal war injuries were the most common causes of previouslaparotomy. During those operations or during entering into abdominal cavity we have not experienced any complications, while in 7 patients we performed conversion to laparotomy following the diagnostic laparoscopy. In all patients an insertion of Veres needle and trocar insertion in the umbilical region was performed, namely a technique of closed laparoscopy. Not even in one patient adhesions in the region of umbilicus were found, and no abdominal organs were injured.

    2014-09-01

    Full Text Available El cognitivismo, enfoque predominante en psicología y ciencias cognitivas en general, constituye un paradigma de comprensión de la mente que, en apariencia, resulta compatible con los postulados materialistas de la ciencia. De esta forma, pareciera que este enfoque fuese el primer intento plenamente científico, concebido para investigar y desarrollar explicaciones acerca de la mente. Sin embargo, examinados algunos elementos centrales del cognitivismo, puede apreciarse que, en su interior, esta perspectiva contiene una maniobra reduccionista que deja fuera algunos componentes centrales de la psique, continuando, de alguna forma, la histórica tradición cartesiana de negación de la mente como fenómeno físico y natural. En este trabajo, se revisan los postulados centrales del cognitivismo, los cuales son analizados a la luz del dualismo de sustancias de René Descartes, para develar cuánto de esta perspectiva filosófica sigue presente en las nuevas ciencias de la mente, restringiendo nuestra comprensión de los procesos cognitivos.

    Aging is accompanied by a decline in several aspects of the cognitive function, having negative personal and socioeconomic impacts. Dietary supplements could be beneficial for preventing age-related cognitive decline. In this context, we examined whether the nutritional supplement Mente Activa® has beneficial effects on aging-related cognitive deficits without inducing side effects. Mente Activa® was administered to old rats (n= 30 treated rats and n= 30 control rats) during 5 months, and the Morris water maze was used to test the learning capacities of the animals. The first assessment was conducted before the nutritional intervention (age of 18-19 months), to determine the baseline of the performance of animals on this test, and the second assessment was performed at the end of the treatment (23-24 moths). In order to examine possible secondary effects of this nutritional supplement, plasma, heart anatomy and liver parameters were evaluated. Our data indicate that supplemented rats showed less escape latency, distance swum, higher use of spatial search strategies, and crossed the former platform location with higher frequency than control rats. These effects were specific of the treatment, indicating that this nutritional supplement has a beneficial effect on spatial memory. On the other hand, the regular intake of Mente Activa® did not induce any negative effects in plasma parameters and heart size. Aged rats under a sustained dietary intake of the nutritional supplement Mente Activa® displayed improved learning and memory abilities compared to the non-treated rats. These results suggest the therapeutic potential and safety of use of Mente Activa® for age-related cognitive deficits, particularly, in the onset of the first cognitive dysfunction symptoms.

    Full Text Available CONTEXTO: Mediunidade, uma experiência humana disseminada pelas diversas sociedades ao longo da história, pode ser definida como uma experiência em que um indivíduo (chamado de médium alega estar em comunicação com, ou sob influência de, uma personalidade falecida ou outro ser não material. Desde o século 19 há uma substancial mas negligenciada tradição de investigações científicas sobre mediunidade e suas implicações para a natureza da mente. OBJETIVO: Discutir a importância histórica e atual da mediunidade para o problema mente-cérebro, focando em estudos que investigam as origens e as fontes das comunicações mediúnicas. MÉTODOS: O artigo inicia-se com uma breve discussão filosófica sobre o que seria evidência para identidade pessoal e sua persistência além do cérebro, então apresenta e analisa as evidências proporcionadas por estudos em mediunidade, incluindo uma análise mais detalhada de dois médiuns muito produtivos: Leonora Piper e Chico Xavier. RESULTADOS: Estudos bem controlados, antigos e recentes, sugerem que médiuns podem exibir habilidades e conhecimentos compatíveis com personalidades falecidas e improváveis de terem sido obtidos por meios ordinários. CONCLUSÕES: O uso de métodos de pesquisa contemporâneos em experiências mediúnicas pode proporcionar a necessária ampliação e diversificação da base empírica para o avanço de nosso entendimento do problema mente-cérebro.

Destaca la necesidad de superar el conflicto histórico entre vitalismo y mecanicismo y de construir un concepto que incorpore la dimensión psíquica como prolongamiento de lo orgánico en lo humano. Busca realizar una articulación entre cuestiones abiertas en la biología y en la física y presenta las ideas de Roger Penrose sobre la relación entre física y mente. Indaga sobre la posibilidad de la física del siglo XX inscribirse en la biología del siglo XXI. Defiende que, para poder concretar este desafío, es imperioso considerar el límite humano para conocer al universo. En base a esta discusión, reafirma que la dimensión psíquica humana puede haber evolucionado a partir de una capacidad biológica anterior de realizar elecciones para preservar la vida.The objective of the article is to broach the problem of body mind duality through the discussion of the concept of normativity of life

    Full Text Available Este artigo pretende analisar a discussão humeana sobre a crença nos corpos, apresentada na seção Do ceticismo quanto aos sentidos, do Tratado da Natureza Humana, e na seção Da Filosofia Acadêmica ou Cética, das Investigações acerca do Entendimento Humano. Em especial, ele procura mostrar que a inteligibilidade da existência externa funda-se em uma atividade da mente, por meio da atuação da imaginação, e pressupõe uma resignificação dos conceitos de mente e de percepção. Para tanto, parte da exposição de alguns pressupostos da questão, tais como a tradução da existência externa nas noções de continuidade e distinção, a separação entre sistema vulgar e filosófico e o significado da rejeição dos sentidos e da razão como possíveis causas da crença no mundo.

    Full Text Available El objetivo de este artículo es revisar algunos aspectos relacionados con el desarrollo de la memoria, particularmente, de los recuerdos autobiográficos y, a partir de ello, evaluar la relación que se ha planteado entre estos últimos y el desarrollo de la teoría de la mente (ToM y la autoconciencia. Para tal fin, se hace una revisión sobre el desarrollo de la memoria y la ToM para, a partir de ello, establecer un vínculo con el surgimiento de la autoconciencia, específicamente la conciencia autonoética propuesta por Tulving. Así, se logra establecer que gracias a la conciencia autonoética, cuando un individuo tiene un recuerdo autobiográfico, realmente está viajando mentalmente al pasado; es decir, está re-experimentando algo que sucedió anteriormente, y que, gracias a la ToM, este es un proceso de re-experimentar y no de imaginar o desear. The objective of this article is to revise some aspects related to memory development, specifically, auto-biographic remembrances and, from this, to evaluate la relation between the latter and the development of mind theory and self-conscience. With this purpose, a revision on memory development and mind theory was carried out in order to establish a link with the appearance of self-conscience, mainly auto-non-ethic conscience, proposed by Tulving. In this way, it has been established that thanks to non-ethic conscience, when an individual has an autobiographic remembrance, he is really mentally traveling to the past; e.g., he is re-experimenting something that happened before and that thanks to mind theory, this is a process of re-experimenting but a process for imagining or wishing.

    2016-04-01

    Full Text Available Research in neuroscience and psychology of learning suggests the existence of inborn “number sense”, localized in specialized brain structures that deal with interpreting the world in terms of numbers. However in the common sense of young people and adults are still strong beliefs that mathematics is something of abstract, difficult and far away from everyday life. How is it possible to build numeracy in children using these innate capacities and fostering the development of the right attitudes towards the mathematical knowledge? The article describes the possible impact on educational practices of the research about the number sense and the role of executive functions in mathematical reasoning. It presents the basic principles of a collection of computer games freely available online (PotenziaMente 2.0 designed specifically to develop lexical, semantic and syntactic aspects of numeracy and increasing the use of executive functions in typical mathematical problem solving for primary school. PotenziaMente 2.0. Costruire la numeracy nella scuola primaria attraverso il gioco computerizzatoLa ricerca in neuroscienze ed in psicologia dell’apprendimento suggerisce già da tempo l’esistenza di un “senso del numero” innato, localizzato in strutture cerebrali specializzate che si occupano di interpretare il mondo in termini numerici. Eppure nel senso comune di giovani e adulti permangono credenze che vedono la matematica come un qualcosa di astratto, difficile e lontano dalla vita quotidiana. Come è possibile costruire la numeracy nei bambini sfruttando queste capacità innate e favorendo lo sviluppo dei giusti atteggiamenti verso il sapere matematico? L’articolo descrive le possibili ricadute educative della ricerca sul senso del numero e sul ruolo delle funzioni esecutive nel ragionamento matematico. Partendo da queste risultanze, presenta poi i principi alla base di una collezione di giochi computerizzati liberamente fruibili online

    2009-01-01

    Full Text Available La teoría de la mente refiere a la habilidad para predecir y explicar el comportamiento de los demás, haciendo referencia a sus estados mentales internos, y es considerada como un aspecto fundamental del desarrollo cognitivo durante los años preescolares. Por otra parte, la capacidad de memoria de trabajo es un sistema que permite mantener en mente un determinado número de representaciones de manera simultánea, y también constituye una habilidad central para el desarrollo cognitivo de la población preescolar. En esta investigación se analizan las relaciones entre el desarrollo de la teoría de la mente y la capacidad de memoria de trabajo en 60 niños y niñas preescolares de entre 5 y 7 años, enfatizando posibles diferencias asociadas con el sexo de los participantes. Para la evaluación de la teoría de la mente se utilizaron 6 pruebas de falsa-creencia, mientras la capacidad de memoria de trabajo fue evaluada por medio de 2 tareas de señalamiento autoordenado. Los resultados revelan diferencias entre los sexos en el desarrollo de la teoría de la mente, y descartan la asociación entre esa misma habilidad y la capacidad de memoria de trabajo. Estos hallazgos se discuten en el contexto del debate actual respecto al de sarrollo de la teoría de la mente y las diferencias entre los sexos en el desarrollo cognitivo.

    Full Text Available OBJETIVO: O transtorno afetivo bipolar está associado ao comprometimento funcional persistente. Apesar de muitas pesquisas demonstrarem que bipolares podem apresentar déficits cognitivos, um número menor de trabalhos avaliou o papel de prejuízos no processamento cognitivo social, a Teoria da Mente (relacionado à capacidade de inferir estados mentais, no aparecimento de sintomas e complicações sociais em bipolares. O objetivo deste trabalho é o de revisar sistemática e criticamente a literatura sobre possíveis alterações do processamento Teoria da Mente no transtorno afetivo bipolar. MÉTODO: Foi realizada uma busca na base de dados Medline por trabalhos publicados em língua inglesa, alemã, espanhola ou portuguesa nos últimos 20 anos, utilizando a frase de busca "Bipolar Disorder"[Mesh] AND "Theory of Mind". Foram procurados por estudos clínicos envolvendo indivíduos bipolares e que empregaram uma ou mais tarefas cognitivas desenvolvidas para a avaliação de habilidades Teoria da Mente. Foram excluídos os relatos de caso e cartas ao editor. A busca inicial resultou em cinco artigos, sendo selecionados quatro. Outros quatro foram também selecionados a partir da leitura dos artigos acima. DISCUSSÃO: Os artigos selecionados avaliaram populações de bipolares adultos e pediátricos, incluindo indivíduos eutímicos, maníacos e deprimidos. A maioria dos trabalhos avaliados sugere que existam prejuízos no processamento Teoria da Mente em portadores de transtorno afetivo bipolar e que estes podem estar por trás dos sintomas e dos déficits funcionais do transtorno afetivo bipolar. CONCLUSÃO: Pesquisas futuras a respeito do tema em questão poderão esclarecer muito acerca do papel das alterações sociocognitivas no surgimento dos sintomas do transtorno afetivo bipolar, bem como ajudar no desenvolvimento de estratégias preventivas e terapêuticas do mesmo.OBJECTIVE: Bipolar disorder is associated to persistent functional

En primera instancia se realiza una descripción de los conceptos de representaciones mentales (Johnson-Laird 1983, 1987, 1990, Norman, 1983 y la metáfora del cerebro como computador (Tulving, 1937, 1950. Posteriormente, se ahonda en el concepto de teoría de la mente tomando como referencia los estudios iniciales de Premack y Woodruff (1978, Rivière (1987, 1991a, 1991b. Se describe la relación entre teoría de la mente y autismo, partiendo de los estudios de Karner (1943. Wing (1981. Desde la teoría-teoría, existen varias teorías psicológicas que tratan de explicar el fenómeno del autismo: la de la Ceguera Mental (Barón-Cohen, Leslie y Frith, 1985, la del Debilitamiento de la Coherencia Central Frith (2003, y la de la Disfunción Ejecutiva (Russel, 2000 y Ozonoff, 2000. Otra de las teorías es la Hobson (1995, quien plantea que los déficits cognitivos y sociales en el autismo son de naturaleza afectiva. Finalmente, es importante destacar que las habilidades deficientes en el autismo son destrezas muy complejas, que dependen no sólo de procesos de planificación y ejecución y de inferencias mentalistas, sino de una coordinación de muchas funciones que actúan simultáneamente.

    Directory of Open Access Journals (Sweden)

    Ángel Pazos-López

    2014-12-01

    Full Text Available El presente artículo es una revisión crítica de las relaciones entre la Historia del Arte y el campo de la Psicología, acotándose el territorio que se ha denominado "Psicología del Arte", dedicado al estudio del arte como producto de la mente humana desde la visión del creador, el receptor y el objeto artístico. El estudio de las ideas que están detrás de las producciones artísticas, o de la sociedad que las descifra y conserva, ha pasado por distintas etapas de desarrollo desde finales del siglo XIX implicando ateóricos del arte, críticos e historiadores, así como a psicoanalistas y psicólogos que han escrito sobre las relaciones entre el arte, la mente y la cultura. Las aportaciones iniciales vinculadas al psicoanálisis de Freud, Jung y Lacan disputaron las primeras posturas filiales y críticas a un campo que se abría. Posteriormente, los escritos de Kris y las teorías de la Psicología del Estilo y de la escuela de la Gestalt serán claves en el devenir de la disciplina. La gran aportación de Vygotsky a la definición de la Psicología del Arte y sus límites, o los estudios de Gombrich dedicados a la psicología de la representación visual fueron la continuación natural de los planteamientos anteriores, así como los trabajos de Gardner o Vigouroux en las últimas décadas. Este recorrido histórico muestra que la Psicología del Arte es una disciplina que ha estado presente transversalmente en muchas corrientes psicológicas, en permanente actualidad, y que necesita una continuidad al hilo de las últimas corrientes de la Psicología.

    Directory of Open Access Journals (Sweden)

    Angela Donato Oliva

    Full Text Available O conhecimento científico da mente humana tem avançado desde a fundação da Psicologia. Aspectos biológicos e culturais, psicológicos e neurológicos, emocionais e racionais foram privilegiados separadamente em diferentes épocas e perspectivas - a visão de mente foi por vezes focalizada e por vezes relegada à caixa preta da ciência psicológica. Contemporaneamente, assiste-se a buscas de integração entre mente e comportamento humanos. A mente é vista como objeto da ciência e produto da seleção natural na evolução da espécie do Homo sapiens sapiens. Este trabalho visa apresentar uma breve história das principais transformações na concepção da mente, e de modelos evolucionistas de mente que contemplem a razão, a emoção e as ações humanas. Busca-se integrar e discutir as evidências das pesquisas de diversas disciplinas (Antropologia, Etologia, Primatologia, Psicologia, etc oferecendo uma compreensão evolucionista da mente humana, de sua filogênese e ontogênese. Comportamentos cooperativos e competitivos serão discutidos a partir dessas perspectivas.

A pesar deque muchas veces intentamos idear cosas nuevas, nuestrocerebro se rehúsa a darnos la formula mágica y esto por dosrazones fundamentales: la vida diaria no nos exige gran nivelde creatividad pues casi todo está dado para facilitarnos laexistencia y la segunda razón es que los moldes tradicionales,en los cuales fuimos formados, han creado en nosotroslimitantes mentales que inhiben nuestro pensamiento.

  5. Occupare spazi, liberare luoghi della mente e della cittadinanza: esperienze di riappropriazione a Roma

    Directory of Open Access Journals (Sweden)

    Irene Ranaldi

    2014-11-01

    Full Text Available Negli ultimi anni l’utilizzo degli spazi pubblici e abitativi è diventato una delle sfide più significative per le amministrazioni locali che si trovano a dover mediare tra gli interessi di soggetti pubblici e privati, associazioni e residenti per migliorare la qualità dei luoghi di vita urbani. Amministratori locali, urbanisti e organizzatori di comunità sono alcuni degli attori di queste nuove forme di cambiamento urbano che emergono dal basso, grazie ad un confronto costante con le esigenze del territorio che spinge ad una rimodulazione di spazi e strutture pubbliche ridando così nuova vita ad interi pezzi di città, spesso abbandonati o dismessi o in annosa attesa di recupero. Esperienze di questo tipo di ri-appropriazione, sia esso con la pratica dell’occupazione o dell’esito di un processo di progettazione partecipata tra cittadini e istituzioni, si susseguono sempre più spesso in Europa e negli Stati Uniti. Come può definirsi uno spazio pubblico? Può essere definito come ogni luogo di proprietà pubblica o di uso pubblico accessibile e fruibile a tutti gratuitamente e senza scopi di lucro. Gli spazi pubblici rappresentano i luoghi della vita collettiva delle comunità e un elemento decisivo per il benessere individuale e sociale in quanto dotati di specifiche caratteristiche spaziali, storiche, ambientali, sociali ed economiche. Lo spazio è una condizione perché le modalità spaziali di esperienza in qualche modo indirizzano il configurarsi delle forme sociali, ma assume un significato sociologico in quanto simbolo della relazione sociale. Riappropriarsi in qualche modo di questo simbolo, declinandone gli esiti in forme differenti di partecipazione, può significare liberare luoghi della mente e dell’espressività.

    Full Text Available Raziskovalno vprašanje (RV: Ali obstajajo statistično značilne povezave med dejavniki planiranja, organiziranja, vodenja in kontroliranja in finančno dodano vrednostjo gradbenih projektov. Namen: Namen raziskave je bil opraviti empirično raziskavo o vplivu dejavnikov menedžment projektov na finančno dodano vrednost v izbranih slovenskih gradbenih podjetjih ter podati predloge za izboljšanje stanja. Metoda: V kvantitativni raziskavi je sodelovalo 77 anketirancev iz slovenskih gradbenih podjetij, med katerimi je bila večina menedžerjev projektov. Rezultati: Na podlagi raziskave je razvidno, da imajo natančneje planirani gradbeni projekti statistično značilen vpliv na finančno dodano vrednost projektov, pri čemer imata največji vpliv ustrezno planiranje in preverjanje ciljev ter obvladovanje sprememb na projektu. Organizacija: Izidi raziskave bodo lahko v praktično pomoč vsem tistim, ki se ukvarjajo s področjem gradbenih projektov in njihovo uspešnostjo.

  7. Máquinas e mentes: interpretando a metáfora

    Directory of Open Access Journals (Sweden)

    2008-04-01

    O artigo tem por objetivo testar a hipótese de Moura (2007 de que as metáforas possuem uma estrutura léxico-conceptual e de que há sistematicidade na interpretação metafórica, ou seja, há uma regularidade interpretativa conforme a classe verbal (ou nominal dos veículos das metáforas. Para chegar ao objetivo, selecionamos alguns verbos de atitude proposicional e procuramos na web exemplos do uso desses verbos em relação a máquinas. Os verbos escolhidos como veículos das metáforas foram: pensar, raciocinar, surtar, pirar, enlouquecer, inventar, criar, decidir, saber, acreditar, entender, aceitar, querer, achar; e os tópicos selecionados: computador, celular, aparelho, televisão, microondas, avião, carro, piloto automático, termostato, aparelho e máquinas. A coleta resultou em 51 exemplos que constituem metáforas ontológicas de personificação e, por causa da relação estreita desse tipo de metáfora com a discussão sobre Inteligência Artificial, foi feita uma breve seção sobre este assunto. A partir dos dados coletados, a análise foi efetuada objetivando parafrasear e buscar relações paradigmáticas e sintagmáticas relativas às metáforas selecionadas. Após a discussão dos resultados, a hipótese pôde ser confirmada e, através da análise, é possível mostrar que há regularidade na interpretação de metáforas cujos tópicos são máquinas e os veículos são verbos de atitude proposicional. Foi averiguado que, quando verbos de atitude proposicional são aplicados metaforicamente a máquinas, visa-se basicamente o funcionamento dos equipamentos e a manipulação de símbolos pelas máquinas, mas não atitudes conscientes ou estados da “mente” das máquinas, o que mostra a limitação da analogia metafórica entre máquinas e mentes.

    Full Text Available The European Space Agency project Satellite Monitoring of Ash and Sulphur Dioxide for the mitigation of Avi­ ation Hazards, was introduced after the eruption of the Icelandic volcano Eyjafjallajökull in the spring of 2010 to facilitate the development of an optimal End­to­End System for Volcanic Ash Plume Monitoring and Predic­ tion. The Eyjafjallajökull plume drifted towards Europe and caused major disruptions of European air traffic for several weeks affecting the everyday life of millions of people. The limitations in volcanic plume monitoring and prediction capabilities gave birth to this observational system which is based on comprehensive satellite­derived ash plume and sulphur dioxide [SO2] level estimates, as well as a widespread validation using supplementary satellite, aircraft and ground­based measurements. Inter­comparison of the volcanic total SO2 column and plume height observed by GOME­2/Metop­A and IASI/Metop­A are shown before, during and after the Eyjaf­ jallajökull 2010 eruptions as well as for the 2011 Grímsvötn eruption. Co­located ground­based Brewer Spectro­ photometer data extracted from the World Ozone and Ultraviolet Radiation Data Centre for de Bilt, the Nether­ lands, are also compared to the different satellite estimates. Promising agreement is found for the two different types of instrument for the SO2 columns with linear regression coefficients ranging around from 0.64 when comparing the different instruments and 0.85 when comparing the two different IASI algorithms. The agree­ ment for the plume height is lower, possibly due to the major differences between the height retrieval part of the GOME2 and IASI algorithms. The comparisons with the Brewer ground­based station in de Bilt, The Nether­ lands show good qualitative agreement for the peak of the event however stronger eruptive signals are required for a longer quantitative comparison.

    Full Text Available BACKGROUND: Theory of mind (ToM is the ability to attribute mental states to other individuals. Its cerebral organization is not enough established, even though the literature suggests the relevant role of the frontal lobes. OBEJECTIVE: To evaluate frontal lobe patients and controls in ToM tests. METHOD:We studied 20 patients with lesions limited to the frontal lobes (as shown by CT or MRI, and 10 normal control subjects by means of ToM tests (recognizing himself in mirrors, false belief, first and second order ToM tasks, as well as tests of other cognitive functions (counter-proofs. RESULTS: Patients and controls performed similarly in ToM tests. There was significant difference between frontal subgroups (left, right, bifrontal in the double-bluff task (second order ToM (p=0.021, without relation to verbal fluency (p=0.302 or delayed recall ability (p=0.159. The only two patients with deficits in ToM tasks had impairment of social behavior. CONCLUSION: Frontal lesions do not necessarily implicate in ToM deficits, which may occur when such lesions are associated to disturbance of social behavior.CONTEXTO: Teoria da mente (TM é a capacidade de atribuir estados mentais aos outros.

    2014-01-01

    For the 20(th) century since the Depression, we find a strong correlation between a 'literary misery index' derived from English language books and a moving average of the previous decade of the annual U.S. economic misery index, which is the sum of inflation and unemployment rates. We find a peak in the goodness of fit at 11 years for the moving average. The fit between the two misery indices holds when using different techniques to measure the literary misery index, and this fit is significantly better than other possible correlations with different emotion indices. To check the robustness of the results, we also analysed books written in German language and obtained very similar correlations with the German economic misery index. The results suggest that millions of books published every year average the authors' shared economic experiences over the past decade.

    RÉSUMÉ OBJECTIF Déterminer si les recommandations véhiculées par les professionnels de la santé sur l’importance de l’acide folique encouragent les femmes susceptibles de procréer de prendre les suppléments d’acide folique. CONCEPTION Enquête. CONTEXTE Centre de santé et de services sociaux, Institut universitaire de gériatrie de Sherbrooke, à Sherbrooke, Qué. PARTICIPANTS 323 femmes francophones âgées entre 18 et 45 ans. PRINCIPALES MESURES DES RÉSULTATS La consommation de suppléments de vitamines et de minéraux au cours de la dernière année. Des analyses statistiques descriptives et bivariées et une modélisation par régression logistique ont été effectuées pour déterminer si l’association observée entre la recommandation d’un professionnel de la santé et la consommation de vitamines et de minéraux persistait après avoir tenu compte de l’effet des variables de contrôle (consultation de documentation, connaissances, sources d’information, perception, âge, scolarité, revenu, état matrimonial, intention de devenir enceinte). RÉSULTATS Environ 41% des femmes rapportent que leur médecin leur avait recommandé de consommer un supplément de vitamines et de minéraux. Après avoir ajusté toutes les variables dans le modèle, il est apparu que le fait de se faire recommander par un professionnel de la santé de prendre un supplément de vitamines et de minéraux était significativement associé à la consommation de vitamines et de minéraux par les femmes susceptibles de devenir enceintes. CONCLUSION Les professionnels peuvent améliorer la santé de la population par une pratique clinique préventive. Nous soulignons l’importance de soutenir ces derniers dans leurs efforts d’intégrer puis d’appliquer des connaissances scientifiques dans leur pratique. PMID:18077754

    Full Text Available O objetivo deste artigo é mostrar que a questão referente aos dois princípios metafísicos constitutivos da antropologia cristã, o corpo/matéria e a alma/espírito, e a forma de conceber a relação entre eles encontra-se presentes no subsolo das novas antropologias materialistas, mas com um novo verniz através da relação entre a mente e o cérebro. Para a antropologia cristã, a existência do binômio corpo-alma é uma questão resolvida. As discussões se concentram na forma de conceber a relação entre ambos os princípios. Analogamente, para algumas antropologias materialistas atuais, a existência da mente e do cérebro é uma questão fechada. Os confrontos encontram-se na forma de conceber as relações entre a mente e o cérebro: há uma identificação ou distinção entres ambas as realidades? A mente seria uma qualidade emergente do cérebro?   ABSTRACT: The purpose of this article is to show that the question concerning the two constituent metaphysical principles of Christian anthropology, body/matter and soul/spirit, and the way of conceiving the relationship between them is presente in the basement of the new materialist anthropologies, but with a new varnish through the relationship between mind and brain. For Christian anthropology, the existence of the binomial soul/body is a settled issue. The discussions focus on how to design the relationship between the two principles. Similarly, for some current materialistic anthropologies, the existence of the mind and the brain is a closed question. The clashes are the way of conceiving the relationship between mind and brain: Is there an identification or a distinction between the two realities? Would be the mind an emergent quality of the brain?

En él se da a conocer el problema de la mente-cerebro-conducta desde la ciencia y la filosofía, con el fin de describir explicar y analizar de forma crítica algunas de las principales posturas teóricas que se han elaborado y que tienen que ver con el desarrollo de la ciencia en particular la física y la filosofía actual. Igualmente, en este artículo se presenta la relación entre el funcionamiento de la mente y el cerebro con la física cuántica, no sin antes presentar algunas de las más representativas teorías sobre la mente como: el dualismo, el funcionalismo y de la complejidad a fin de contextualizar la relación antes mencionada mentecerebro- conducta. Por otro lado, el análisis que se hace sobre el comportamiento del mundo subatómico desde la teoría cuántica y en el que va implícito una postura indeterminista nos lleva a plantear problemas acerca de la mente, el cerebro, la conducta y, particularmente, el comportamiento ético, (el problema del libre albedrío. En dicho análisis surgen interrogantes que dan lugar a la reflexión como, por ejemplo: ¿si se tomara el modelo de la física cuántica se podría llegar a considerar que el cerebro está constituido de mínimas incertidumbres, que serían el resultado de fluctuaciones cuánticas?, ¿esas irregularidades podrían traducirse en comportamientos atípicos, creativos y originales en los individuos?

    To gain awareness on natural hazards social and educational initiatives are required, aimed at promoting a civil protection culture able to guide towards conscious and correct behavior. People, well-informed about risks in their territory, are safer citizens. In this perspective, it is important that the learning environments, such as schools and universities, play a key role on promoting dialogue and interactions among institutions, becoming a useful resource for the local community. In this framework, the present work describes an experimental project, called SicuraMente, started 2 years ago, about safety and civil protection culture coordinated by LARES Italia, a national civil protection association. This ongoing project, that involves high school and university students, is a training course that teaches skills and grants its participants specific toolset to increase the civic awareness and personal knowledge on actions to take in specific emergency situations. SicuraMente is a multi-hazard project, concerning several natural phenomena such as earthquake, flood, landslide, fire and extreme meteorological events. Each topic is discussed with a global approach starting from the scientific knowledge of the phenomenon, with a final discussion on the best practices about disaster prevention and preparedness. Additionally, in order to encourage the interest of students, 4 contexts are taken in example (home, school, city, society) with special case study sessions of each, with open discussion and debate. The project's activities are conducted on two levels: peer education lessons with "learning by doing" approach (e.g. simulation-based learning) under the coordination of LARES volunteers, and a further training stage at home in e-learning environment (www.sicuramentelab.it). In the first year of the project, 669 students from 9 schools of Regione Umbria (Central Italy) were involved. Thanks to the fundamental support of the volunteers of LARES association, 543

    . Las evidencias presentadas demuestran que los juegos de simulacro se constituyen como setting para la flexibilización del pensamiento y también para el surgimiento de competencias importantes para el desarrollo de una teoría de la mente.This article examines the relationship between some basic operations of the development of a theory of mind, as an interactional tool, and abilities that base the make-believe play. Theory of mind is understood as a conjunct of abilities that equips a child to comprehend, make references, and also consider own and other's mental states, differentiating them and socially operating through this comprehension. Make-believe play is understood, in this study, as a setting of playful action in which a child operates in an imaginary dominion, that it is neither limited to the concrete reality nor equivalent to it. Based in some assumptions, previously approached by many authors, about the relationship between the development of sociocognitive abilities and the acquisition a theory of mind, the observation and analysis of a communicative interaction between a 3.9-year-old child and his mother is discussed. Through some evidences, it is demonstrated that make-believe games constitute a setting that promotes flexibility of thinking and the appearance of some abilities meanly important to the development of a theory of mind.

Les objectifs de notre étude étaient de déterminer le niveau de fardeau et de la dépression chez les aidants familiaux de sujets déments, et d'identifier les facteurs associés à un niveau de fardeau élevé. Méthodes Il s'agissait d'une enquête auprès de 65 aidants tunisiens. Les niveaux de fardeau et de la dépression ont été évalués par, respectivement, l'inventaire de Zarit et l’échelle de Beck. Résultats Le taux des aidants qui avaient un niveau de fardeau élevé était de 52,3 %. Une dépression modérée ou sévère a été relevée chez 46,2 %. Un niveau de fardeau élevé était corrélé, du côté de l'aidant, avec le niveau socio-économique moyen à élevé, la cohabitation avec le patient, le fait d’être son conjoint, la réduction des activités quotidiennes et la sévérité de la dépression, et, du côté du dément, avec l'agressivité. Conclusion Les facteurs corrélés à un niveau de fardeau élevé orientent vers les cibles d'intervention et sont susceptibles d’être améliorés par la prise en charge, ce qui contribuerait à alléger la détresse des aidants.

    Full Text Available Abstract The Theory of Mind is one of the most important contributions neuroscience has made to the study of social behavior in both human and nonhuman primates. This study establishes important hypotheses about the deficiencies in social interaction experienced by patients with different disorders such as autism, schizophrenia and stroke among others. In addition, this theory established a line of development in social interaction in healthy subjects which is important because it will create training programs with better levels of effectiveness. In this article, we review retrospective and prospective research advances of the Theory of Mind in neuroscience, as well as tools for evaluation and neuroanatomical and neuropsychological aspects of the theory. Resumen La Teoría de la Mente constituye uno de los aportes más importantes que se ha hecho desde la Neurociencia al estudio de la conducta social, tanto en primates humanos como no humanos. Su estudio ha permitido establecer importantes hipótesis sobre las deficiencias en la interacción social que presentan pacientes con diferentes trastornos como el autismo, la esquizofrenia, accidentes cerebro-vasculares, entre otros; pero, además, esta teoría ha permitido establecer una línea de desarrollo en la interacción social en sujetos sanos, lo cual es importante porque permitirá crear programas de entrenamiento con mejores grados de eficacia. En este artículo, se hace una revisión retrospectiva y prospectiva de los avances de investigación de la Teoría de la Mente en las Neurociencias, así como de las herramientas para su evaluación y de los aspectos neuroanatómicos y neuropsicológicos de la misma.

    Full Text Available Um constructo nascido da psicologia cognitiva e que se refere à capacidade de atribuir estados mentais para si mesmo e para os outros, denominado Teoria da Mente, tem sido exportado para outros campos do saber e tem sido mais recentemente incorporado pela psicologia médica com a pretensão de explicar determinadas alterações de comportamento que constituem o cerne de distúrbios como o Autismo Infantil, Esquizofrenia e Psicoses afins. Esta incorporação trouxe a necessidade de desenhar metodologias que possam mensurar e definir a Teoria da Mente em termos neurobiológicos. Nos objetivamos a descrever os mecanismos pelos quais a Teoria da Mente tem contribuído para o esclarecimento de alguns fenômenos mentais, bem como arrolar as dificuldades metodológicas associadas a tal empreedimento. Antes disto, uma revisão geral da Teoria da Mente é proporcionada enfocando os aspectos mais relevantes do constructo. Existem poucos trabalhos nesta área no Brasil, razão pela qual justificamos a reflexão conduzida.

    To determine the frequency of tests done in the year before elective surgery that might substitute for preoperative screening tests and to determine the frequency of test results that change from a normal value to a value likely to alter perioperative management. Retrospective cohort analysis of computerized laboratory data (complete blood count, sodium, potassium, and creatinine levels, prothrombin time, and partial thromboplastin time). Urban tertiary care Veterans Affairs Hospital. Consecutive sample of 1109 patients who had elective surgery in 1988. At admission, 7549 preoperative tests were done, 47% of which duplicated tests performed in the previous year. Of 3096 previous results that were normal as defined by hospital reference range and done closest to the time of but before admission (median interval, 2 months), 13 (0.4%; 95% CI, 0.2% to 0.7%), repeat values were outside a range considered acceptable for surgery. Most of the abnormalities were predictable from the patient's history, and most were not noted in the medical record. Of 461 previous tests that were abnormal, 78 (17%; CI, 13% to 20%) repeat values at admission were outside a range considered acceptable for surgery (P less than 0.001, frequency of clinically important abnormalities of patients with normal previous results with those with abnormal previous results). Physicians evaluating patients preoperatively could safely substitute the previous test results analyzed in this study for preoperative screening tests if the previous tests are normal and no obvious indication for retesting is present.

    Background and purpose - Patients with osteoporosis who present with an acute onset of back pain often have multiple fractures on plain radiographs. Differentiation of an acute osteoporotic vertebral fracture (AOVF) from previous fractures is difficult. The aim of this study was to investigate the incidence of concomitant AOVFs and previous OVFs in patients with symptomatic AOVFs, and to identify risk factors for concomitant AOVFs. Patients and methods - This was a prospective epidemiological study based on the Registry of Pathological Osteoporotic Vertebral Fractures (REPAPORA) with 1,005 patients and 2,874 osteoporotic vertebral fractures, which has been running since February 1, 2006. Concomitant fractures are defined as at least 2 acute short-tau inversion recovery (STIR-) positive vertebral fractures that happen concomitantly. A previous fracture is a STIR-negative fracture at the time of initial diagnostics. Logistic regression was used to examine the influence of various variables on the incidence of concomitant fractures. Results - More than 99% of osteoporotic vertebral fractures occurred in the thoracic and lumbar spine. The incidence of concomitant fractures at the time of first patient contact was 26% and that of previous fractures was 60%. The odds ratio (OR) for concomitant fractures decreased with a higher number of previous fractures (OR =0.86; p = 0.03) and higher dual-energy X-ray absorptiometry T-score (OR =0.72; p = 0.003). Interpretation - Concomitant and previous osteoporotic vertebral fractures are common. Risk factors for concomitant fractures are a low T-score and a low number of previous vertebral fractures in cases of osteoporotic vertebral fracture. An MRI scan of the the complete thoracic and lumbar spine with STIR sequence reduces the risk of under-diagnosis and under-treatment.

    The complexity of giving psychiatrically disabled persons access to work is well known. The percentage of persons thus defined who are on the provincial unemployment lists is constantly increasing. The 'Lavoro Liberamente" ('I work freely') project is aimed not only at enabling a number of psychiatric patients to gain access to work but to do so by experimenting with a network methodology that includes the various agencies that can contribute to a successful outcome. The project was developed in various stages--psychiatric services and company awareness campaigns and task-definition, candidate selection, skills assessment, and work placement--all aimed at finding and maintaining employment. After a thorough preparatory phase, 19 psychiatrically disabled persons were placed in 14 companies. When the apprenticeship was concluded, 13 of them were hired. Considering the short time-frame--about one year between candidates being selected and finally recruited--the ratio between the number of disabled people recruited and those placed was satisfactory. This result should be interpreted positively because, even taking into account some of the most sensitive issues that surfaced and were analysed, it shows that access of the psychiatrically disadvantaged to work is possible if all involved people work synergistically, each according to their responsibilities and knowledge, and on condition that a recognised management of each individual project exists. Within such a network synergism, it is even possible to identify some tasks that are the responsibility of the Occupational Health Physician, therefore further contributing to the overall success of placements.

En esta investigación, se hace un análisis del taoísmo, tradición de la antigua civilización China y sus conexiones con la reflexión occidental sobre la energía, la mente humana y la naturaleza. En el pensamiento taoísta, hay una visión de unidad indisoluble entre hombre y naturaleza. El hombre mismo hace parte de la unidad del cosmos: él mismo es naturaleza. Desde esta perspectiva, se analizan algunos de los aportes que esta milenaria tradición hace a la investigación actual sobre ciencia y espiritualidad y a la comprensión de nuevos discursos que se constituyen en temas fronterizos entre la fe y la ciencia contemporánea.

    The paper presents the open boundary modelling method using transformation. This method may be summarized by the use of mappings which link the real open domain with an image closed domain. This image domain is then meshed by classical finite element. The best method to take the transformation into account is to consider that the elements of the image domain allow to define finite elements and shape functions on the real domain. This new set of finite elements, called the mapped infinite elements, are able to simulate infinite domain. The paper also presents results obtained using this method. They show the value of the method as well as its limits. L'article présente la méthode de modélisation éléments finis de l'infini à l'aide de transformations. Cette méthode peut se résumer par l'utilisation de transformations reliant le domaine ouvert à un domaine fermé image, qui est alors maillé en éléments finis classiques. L'application locale de la transformation sur les éléments du domaine image permet de définir de nouveaux éléments. Ces nouveaux éléments, appelés éléments finis transformés, peuvent s'étendre jusqu'à l'infini et sont donc capables de prendre en compte les domaines à frontières ouvertes. L'article présente aussi les demiers résultats obtenus à l'aide de cette méthode. Les grandeurs calculées aux moments de l'exploitation sont les grandeurs les plus difficiles qu'ils soient, puisqu'il s'agit de grandeurs locales (champ-potentiel) dans le domaine extérieur étant entendu que les autres grandeurs (grandeurs globales comme les forces ou l'énergie, ou grandeurs locales dans le domaine intérieur) sont bonnes. Ces résultats montrent la valeur (ce qui signifie aussi les limites) de la méthode proposée.

    The incidence of cesarean section has been rising in the past 50 years. With the increased number of cesarean sections, the number of pregnancies with the previous cesarean section rises as well. The aim of this study was to establish the influence of the previous cesarean section on the development of placental complications: placenta previa, placental abruption and placenta accreta, as well as to determine the influence of the number of previous cesarean sections on the complication development. The research was conducted at the Clinic of Gynecology and Obstetrics in Nis covering 10-year-period (from 1995 to 2005) with 32358 deliveries, 1280 deliveries after a previous cesarean section, 131 cases of placenta previa and 118 cases of placental abruption. The experimental groups was presented by the cases of placenta previa or placental abruption with prior cesarean section in obstetrics history, opposite to the control group having the same conditions but without a cesarean section in medical history. The incidence of placenta previa in the control group was 0.33%, opposite to the 1.86% incidence after one cesarean section (pcesarean sections and as high as 14.28% after three cesarean sections in obstetric history. Placental abruption was recorded as placental complication in 0.33% pregnancies in the control group, while its incidence was 1.02% after one cesarean section (pcesarean sections. The difference in the incidence of intrapartal hysterectomy between the group with prior cesarean section (0.86%) and without it (0.006%) shows a high statistical significance (pcesarean section is an important risk factor for the development of placental complications.

    Full Text Available Introduction The rate of operative birth by Caesarean section is constantly rising. In Kazakhstan, it reaches 27 per cent. Research data confirm that the percentage of successful vaginal births after previous Caesarean section is 50–70 per cent. How safe the induction of vaginal birth after Caesarean (VBAC remains unclear. Methodology The studied techniques of labour induction were amniotomy of the foetal bladder with the vulsellum ramus, intravaginal administration of E1 prostaglandin (Misoprostol, and intravenous infusion of Oxytocin-Richter. The assessment of rediness of parturient canals was conducted by Bishop’s score; the labour course was assessed by a partogram. The effectiveness of labour induction techniques was assessed by the number of administered doses, the time of onset of regular labour, the course of labour and the postpartum period and the presence of complications, and the course of the early neonatal period, which implied the assessment of the child’s condition, described in the newborn development record. The foetus was assessed by medical ultrasound and antenatal and intranatal cardiotocography (CTG. Obtained results were analysed with SAS statistical processing software. Results The overall percentage of successful births with intravaginal administration of Misoprostol was 93 per cent (83 of cases. This percentage was higher than in the amniotomy group (relative risk (RR 11.7 and was similar to the oxytocin group (RR 0.83. Amniotomy was effective in 54 per cent (39 of cases, when it induced regular labour. Intravenous oxytocin infusion was effective in 94 per cent (89 of cases. This percentage was higher than that with amniotomy (RR 12.5. Conclusions The success of vaginal delivery after previous Caesarean section can be achieved in almost 70 per cent of cases. At that, labour induction does not decrease this indicator and remains within population boundaries.

    Resurgence refers to the recurrence of an extinguished target behavior following subsequent suspension of alternative reinforcement. Delivery of reinforcers during extinction of alternative behavior has been shown to mitigate resurgence. The present experiment aimed to determine whether delivering stimuli associated with reinforcers during resurgence testing similarly mitigates resurgence. Three groups of rats pressed target levers for food according to variable-interval 15-s schedules during Phase 1. In Phase 2, lever pressing was extinguished, and an alternative nose-poke response produced alternative reinforcement according to a variable-interval 15-s schedule. Food reinforcement was always associated with illumination of the food aperture and an audible click from the pellet dispenser during Phases 1 and 2. Phase 3 treatments differed between groups. For one group, nose poking continued to produce food and food-correlated stimuli. Both of these consequences were suspended for a second group. Finally, nose poking produced food-correlated stimuli but not food for a third group. Target-lever pressing resurged in the group that received no consequences and in the group that received only food-correlated stimuli for nose poking. Resurgence, however, was smaller for the group that received food-correlated stimuli than for the group that received no consequences for nose poking. Target-lever pressing did not increase between phases in the group that continued to receive food and associated stimuli. Thus, delivery of stimuli associated with food reinforcement after suspension of food reduced but did not eliminate resurgence of extinguished lever pressing. These findings contribute to potential methodologies for preventing relapse of extinguished problem behavior in clinical settings. © 2017 Society for the Experimental Analysis of Behavior.

    1999-08-01

    To examine the healthcare utilization and costs of previously uninsured rural children. Four years of claims data from a school-based health insurance program located in the Mississippi Delta. All children who were not Medicaid-eligible or were uninsured, were eligible for limited benefits under the program. The 1987 National Medical Expenditure Survey (NMES) was used to compare utilization of services. The study represents a natural experiment in the provision of insurance benefits to a previously uninsured population. Premiums for the claims cost were set with little or no information on expected use of services. Claims from the insurer were used to form a panel data set. Mixed model logistic and linear regressions were estimated to determine the response to insurance for several categories of health services. The use of services increased over time and approached the level of utilization in the NMES. Conditional medical expenditures also increased over time. Actuarial estimates of claims cost greatly exceeded actual claims cost. The provision of a limited medical, dental, and optical benefit package cost approximately $20-$24 per member per month in claims paid. An important uncertainty in providing health insurance to previously uninsured populations is whether a pent-up demand exists for health services. Evidence of a pent-up demand for medical services was not supported in this study of rural school-age children. States considering partnerships with private insurers to implement the State Children's Health Insurance Program could lower premium costs by assembling basic data on previously uninsured children.

Both are fundamental heuristic tools, being the first, the modular theory of mind, which enables us to understand important aspects of human cognition such as language, memory, learning (cognitive sciences. The second, the ornamental mind theory, explains certain apparent wasteful behaviors. The fundamental presuppositions of both metaphors are distinct: whilst the modular model is a product of cognitive sciences, the ornamental model is the yield of the sexual selection principle. Basically, as heuristic tools, the modular theory demonstrates the mind as a computation, as a product of selection (natural selection which processes information; on its turn, the ornamental mind theory proposes an awkward idea, which Amotz Zahavi called the handicap principle (sexual selection.

    Sentinel lymph node (SLN) biopsy is the standard of care for axillary staging in breast cancer, but many clinical scenarios questioning the validity of SLN biopsy remain. Here we describe our experience with reoperative-SLN (re-SLN) biopsy after previous mastectomy. Review of the SLN database from September 1996 to December 2007 yielded 20 procedures done in the setting of previous mastectomy. SLN biopsy was performed using radioisotope with or without blue dye injection superior to the mastectomy incision, in the skin flap in all patients. In 17 of 20 patients (85%), re-SLN biopsy was performed for local or regional recurrence after mastectomy. Re-SLN biopsy was successful in 13 of 20 patients (65%) after previous mastectomy. Of the 13 patients, 2 had positive re-SLN, and completion axillary dissection was performed, with 1 having additional positive nodes. In the 11 patients with negative re-SLN, 2 patients underwent completion axillary dissection demonstrating additional negative nodes. One patient with a negative re-SLN experienced chest wall recurrence combined with axillary recurrence 11 months after re-SLN biopsy. All others remained free of local or axillary recurrence. Re-SLN biopsy was unsuccessful in 7 of 20 patients (35%). In three of seven patients, axillary dissection was performed, yielding positive nodes in two of the three. The remaining four of seven patients all had previous modified radical mastectomy, so underwent no additional axillary surgery. In this small series, re-SLN was successful after previous mastectomy, and this procedure may play some role when axillary staging is warranted after mastectomy.

    Full Text Available Background: Whereas the effects of various socio-demographic determinants on a woman's risk of having an abortion are relatively well-documented, less attention has been given to the effect of previous abortions and births. Objective: To study the effect of previous abortions and births on Danish women's risk of an abortion, in addition to a number of demographic and personal characteristics. Data and methods: From the Fertility of Women and Couples Dataset we obtained data on the number of live births and induced abortions by year (1981-2001, age (16-39, county of residence and marital status. Logistic regression analysis was used to estimate the influence of the explanatory variables on the probability of having an abortion in a relevant year. Main findings and conclusion: A woman's risk of having an abortion increases with the number of previous births and previous abortions. Some interactions were was found in the way a woman's risk of abortion varies with calendar year, age and parity. The risk of an abortion for women with no children decreases while the risk of an abortion for women with children increases over time. Furthermore, the risk of an abortion decreases with age, but relatively more so for women with children compared to childless women. Trends for teenagers are discussed in a separate section.

O objetivo do presente estudo foi investigar se a aquisição de uma teoria da mente está associada à habilidade de compartilhar emoções e à motivação pró-social nos anos pré-escolares. Trinta e sete crianças com idade entre 4 e 6 anos participaram de tarefas de teoria da mente e de uma tarefa de empatia e motivação pró-social criada para este estudo. Os resultados não indicaram uma correlação significativa entre o desempenho nas tarefas de teoria da mente e o grau de empatia das crianças. A motivação pró-social, por outro lado, foi significativamente associada à teoria da mente. Os resultados sugerem que uma compreensão mais sofisticada dos estados mentais subjacentes às ações humanas não seja pré-requisito para uma resposta emocional empática, mas possa influenciar positivamente o comportamento pró-social.Hay discordancia entre investigadores del campo de desarrollo socio-cognitivo cuanto a los factores relacionados al desarrollo de la empatía y de la motivación para actuar de manera prosocial.

    Congruency effects in distracter interference tasks are often smaller after incongruent trials than after congruent trials. However, the sources of such congruency sequence effects (CSEs) are controversial. The conflict monitoring model of cognitive control links CSEs to the detection and resolution of response conflict. In contrast, competing theories attribute CSEs to attentional or affective processes that vary with previous-trial congruency (incongruent vs. congruent). The present study s...

    Full Text Available O objetivo deste estudo foi investigar a relação entre teoria da mente e julgamento moral (com base na intenção e com base no motivo em uma amostra de crianças brasileiras de idade pré-escolar. Vinte e quatro crianças de 4 e 5 anos foram avaliadas por tarefas de teoria da mente e de julgamento moral. Embora a correlação entre os desempenhos nos dois tipos de tarefa não tenha se mostrado significativa, alguns efeitos importantes foram encontrados: os participantes tiveram mais facilidade para julgar os comportamentos propositais do que os acidentais; e as crianças de 5 anos tiveram um desempenho melhor do que as de 4 anos na tarefa de julgamento moral com base no motivo. Esses resultados sugerem que um julgamento moral mais sofisticado está associado a uma capacidade de diferenciar ações intencionais e não intencionais, bem como de identificar os motivos subjacentes à ação humana.

    Full Text Available A relação fisioterapeuta-paciente é usualmente caracterizada por momentos de tensão, originados da co-existência de seus diferentes mundos subjetivos, constituídos por concepções e valores diversos, incluindo-se aqueles atinentes à relação corpo-mente. Neste artigo, abordamos, através de relato de pesquisa com delineamento de estudo de caso, algumas das questões relacionadas às tensões intersubjetivas nesse contexto. Apresentaremos resultados da análise do diálogo entre uma fisioterapeuta e sua paciente que evidenciam suas perspectivas conflitantes quanto à relação corpo-mente, com desdobramentos específicos para o processo terapêutico assim como para aspectos gerais da vida cotidiana e profissional das participantes da relação. A análise do diálogo também evidenciou que a busca pela solução dos conflitos gerou, em alguns momentos, novas perspectivas na abordagem das participantes quanto aos temas dos diálogos e à própria relação fisioterapeuta- paciente. Pensamos que a reflexão e discussão desses aspectos nos campos da interdisciplinaridade entre Psicologia e fisioterapia podem gerar novas perspectivas de abordagem das relações envolvidas nesses contextos de atuação profissional.

    This study describes the study approach and field procedures of the MentDis_ICF65+ study, which aims to assess the prevalence of mental disorders in older adults. An age-appropriate version of the Composite International Diagnostic Interview (CIDI65+) was developed and tested with regard to its feasibility and psychometric properties in a pre-test and pilot phase. In the cross-sectional survey an age-stratified, random sample of older adults (65-84 years) living in selected catchment areas of five European countries and Israel was recruited. N = 3142 participants (mean age 73.7 years, 50.7% female) took part in face-to-face interviews. The mean response rate was 20% and varied significantly between centres, age and gender groups. Sociodemographic differences between the study centres appeared for the place of birth, number of grandchildren, close significants, retirement and self-rated financial situation. The comparison of the MentDis_ICF65+ sample with the catchment area and country population of the study centres revealed significant differences, although most of these were numerically small. The study will generate new information on the prevalence of common mental disorders among older adults across Europe using an age-appropriate, standardized diagnostic instrument and a harmonized approach to sampling. Generalizability of the findings and a potentially limited representativeness are discussed.

    Full Text Available Diversos estudos em psicologia, antropologia e sociologia desenvolveram a concepção na qual a mente é vista como algo que "se estende além da pele". O presente trabalho apresenta, no âmbito do ensino de física quântica, uma investigação sobre a distribuição social da mente a partir da análise de uma atividade desenvolvida com um grupo de graduandos em Física, mediada por um interferômetro virtual de Mach-Zehnder. Nossa análise mostrou que, nos debates mais polêmicos, a construção de significados na atividade surgiu por meio de um processo complexo de interanimação de vozes, no qual é impossível determinar quem solucionou o problema, assinalando um ou outro indivíduo isoladamente isto é, foi o grupo, enquanto "sistema", que desempenhou tal função no plano intermental.

    1997-01-01

    Economic evaluations and recent experience show that the deepwater Gulf of Mexico (GOM) is much more profitable than previously thought. Four factors contributing to the changed viewpoint are: First, deepwater reservoirs have proved to have excellent productive capacity, distribution, and continuity when compared to correlative-age shelf deltaic sands. Second, improved technologies and lower perceived risks have lowered the cost of floating production systems (FPSs). Third, projects now get on-line quicker. Fourth, a collection of other important factors are: Reduced geologic risk and associated high success rates for deepwater GOM wells due primarily to improved seismic imaging and processing tools (3D, AVO, etc.); absence of any political risk in the deepwater GOM (common overseas, and very significant in some international areas); and positive impact of deepwater federal royalty relief. This article uses hypothetical reserve distributions and price forecasts to illustrate indicative economics of deepwater prospects. Economics of Shell Oil Co.'s three deepwater projects are also discussed

    Full Text Available Este artigo é uma apresentação dos fundamentos da teoria modular desenvolvida por Jerry A. Fodor e uma reflexão sobre seus principais desafios. A noção de modularidade da mente de Fodor, por um lado, procura superar as insuficiências metodológicas e epistemológicas do associacionismo e do localizacionismo a respeito das explicações da estrutura e do funcionamento mental; por outro lado, é uma oposição à postura culturalista de Vygotsky, para o qual as funções superiores da mente, como a cognição, são produtos artificiais, culturais. A psicologia cognitiva de Chomsky converteu esse produto "artificial" em "natural", postulando a existência de módulos inatos para desempenhar funções cognitivas específicos. Com base nessa ideia de Chomsky, Fodor procura explicar a mente como um conjunto de módulos. No entanto, sua principal contribuição para as ciências cognitivas é a apresentação da arquitetura mental em dois níveis e a afirmação da existência de módulos centrais responsáveis pelas atividades cognitivas superiores, como criatividade, reflexão ou imaginação.The aim of this paper is to present the basic elements regarding the modular theory developed by Jerry A. Fodor and some considerations about its main challenges. Fodor's notion of mind modularity, on the one hand, aims at overcoming the methodological and epistemological gaps of associationism and localizationism concerning the explanations of the structure and functioning of the mind; on the other hand, Fodor's notion stands as an opposition to Vygotsky's culturalist posture, since for the latter the higher functions of the mind, such as cognition, are artificial and cultural products. Chomsky's cognitive psychology has converted this "artificial" product into a "natural" one, postulating the existence of innate modules to perform specific cognitive functions. Based on Chomsky's idea, Fodor describes the mind as a group of modules. However, his main

    Full Text Available El concepto "psicosomático" trae consigo una pesada carga semántica que tiene sus raíces en el dualismo filosófico, acentuado en la propuesta cartesiana, que ha permeado la racionalidad moderna y con ella la concepción de la enfermedad, tanto en el campo de la medicina como de la psicología. En esta revisión teórica se expone una breve discusión en torno al concepto "psicosomático", esbozando las principales perspectivas en el abordaje de la relación mente-cuerpo. Se concluye como necesaria la revisión de las posiciones dualistas y la incorporación de una nueva mirada de las nociones de salud y enfermedad, a partir de la cual el concepto psicosomático se hace redundante.

    Full Text Available La teoría de la mente estudia la habilidad para predecir las conductas del ser humano y para inferir sus estados mentales que permitan un conocimiento anticipado del otro. Las últimas investigaciones han mostrado que este concepto tiene una alta aplicabilidad en lo relacionado con la interacción social. Por otro lado, el enfoque sociohistórico propuesto por Vigotsky, plantea que los procesos psicológicos superiores son generados por la vida en comunidad y por la cultura. Debido a aplicabilidad de la teoría de la mente en la interacción social, es fácil mostrar la relación que hay entre ambas perspectivas y su potencial para la educación. El presente artículo de reflexión presenta argumentos desde los cuales se puede vislumbrar la incursión de las neurociencias en la formación socioafectiva en la escuela. AbstractThe theory of mind studies the ability to predict the behavior of human beings and to infer their mental states and allow advance knowledge of the other. The recent research has shown that this concept has a high applicability in relation to social interaction. On the other hand, socio-historical approach proposed by Vygotsky suggests that higher mental processes are generated by community life and culture. Because applicability of the theory of mind in social interaction, it is easy to show the relationship between the two perspectives and their potential for education. This reflection article presents arguments from which it can glimpse the incursion of the socio-affective neuroscience training in school.

    Danilo Saretta Verissimo

    2009-06-01

    Full Text Available Neste artigo, apresentamos as críticas de Henri Bergson e de Maurice Merleau-Ponty aos enfoques materialistas do problema corpo-mente. Tais enfoques são intrinsecamente ligados às ambições científicas, inauguradas com a modernidade, de totalizar os fenômenos que nos circundam e de unificar a diversidade do mundo através de um único padrão explicativo. Bergson, em uma espécie de fenomenologia do ato perceptivo, buscou suplantar as teses materialistas da relação entre mente e cérebro. Atendo-se ao paralelismo psicofisiológico, mostrou que a percepção atende às necessidades do ser vivo. Além disso, abordou a relação entre memória e cérebro, combatendo a ideia de que as recordações possuam uma tal natureza que permita que elas sejam armazenadas na massa cerebral. Já Merleau-Ponty, n’A Estrutura do Comportamento, após realizar a crítica das concepções clássicas do funcionamento nervoso e depois de se apropriar dos resultados de pesquisas que apresentam o cérebro enquanto entidade coordenadora da estrutura do comportamento, apresenta uma visão do funcionamento nervoso apoiada no primado do mundo percebido a partir da noção de forma. Discutimos, ainda, as heranças filosóficas legadas por Bergson a Merleau-Ponty e algumas críticas deste à obra do seu antecessor.

    The aim of this study was to characterize the treatment response and serious adverse events of ledipasvir plus sofosbuvir therapies in Japanese patients infected with hepatitis C virus (HCV) genotype 1 (GT1). This retrospective study analyzed 240 Japanese HCV GT1 patients treated for 12 weeks with 90 mg of ledipasvir plus 400 mg of sofosbuvir daily. Sustained virological response at 12 weeks post-treatment (SVR12) was achieved in 236 of 240 (98.3%) patients. Among treatment-naïve patients, SVR12 was achieved in 136 of 138 (98.6%) patients, and among treatment-experienced patients, SVR12 was achieved in 100 of 102 (98.0%) patients. In patients previously treated with peginterferon plus ribavirin with various HCV NS3/4A inhibitors, 100% SVR rates (25/25) were achieved. Two relapsers had HCV NS5A resistance-associated variants (RAVs), but no HCV NS5B-S282 was observed after they relapsed. We experienced two patients with cardiac events during treatment. In conclusion, combination of ledipasvir plus sofosbuvir for 12 weeks is a potential therapy for HCV GT1 patients. Caution is needed for HCV NS5A RAVs, which were selected by HCV NS5A inhibitors and cardiac adverse events.

  16. La iluminación agustiniana como explicación de los contenidos de la mente: Agustín en Casicíaco

    Full Text Available Se examina en este trabajo la teoría agustiniana de la iluminación del período de Casicíaco. Lo temprano de su manifestación revela su carácter más filosófico que teológico. Proteo es figura de la verdad que se resiste a darse a conocer, pero que mediante la auctoritas (Cristo y la ratio puede ser hallada, como se muestra en Contra Académicos. De este modo, en Soliloquios, la ratio se presenta como mediadora entre el alma y Dios. Se utiliza aquí la oración como método de introspección e investigación filosófica. Se concluye que la iluminación abarca tanto la verdad objetiva como al receptor de esa verdad, la mente; y que esa misma mente en que las verdades eternas son reconocidas debe ser inmortal, como aquellas lo son: así, la senda que conduce al conocimiento de Dios, pasa por el conocimiento de nosotros mismosAugustine's Theory of Illumination from the Cassisiacum period is examined in this work. The early appearance of the theory reveals its character as of a more philosophical than theological kind. Proteus is a figure of the truth resisting discovery, but which can be found through auctoritas (Christ and ratio as it is shown in Contra Académicos. Thus ratio shows itself in Soliloquia as mediating between the soul and God. Prayer as a method of introspection and philosophical research is used. The author concludes that illumination includes as much the objective truth as the receiver of that truth-the mind; and that this same mind, in which the eternal truths are recognized, must be immortal, as they themselves are. In this way, the path which leads to the knowledge of God passes through the knowledge of our very selves

    Full Text Available Au Brésil comme au Maroc, le secteur agricole est marqué par des différences extrêmes en termes de taille d’exploitation, ainsi que de niveaux d’équipement, de capitalisation et de techniques. L’article présente la politique brésilienne d’appui à l’agriculture familiale, et quelques éléments de comparaison avec les choix faits au Maroc. Les politiques agricoles brésiliennes proposent depuis une vingtaine d’années un appui spécifique aux exploitations familiales, avec notamment la constitution d’un ministère spécifique. De nombreux dispositifs d’appui à l’agriculture familiale ont été mis en place, dont notamment des crédits à taux préférentiel et des programmes d’achat de denrées agricoles pour les institutions publiques (écoles, hôpitaux, etc.. Dans les zones rurales particulièrement fragiles, des dispositifs permettent une coordination entre l’ensemble des politiques publiques concernant ces zones. Enfin, la conception et la mise en oeuvre de ces politiques publiques se font avec une forte implication des syndicats agricoles. Les politiques publiques brésiliennes et marocaines reconnaissent la dualité du monde agricole, mais cette dualité est définie par zone au Maroc, tandis qu’elle est fondée sur des caractéristiques explicites des exploitations au Brésil. Dans les deux pays, le coeur des politiques publiques d’appui aux exploitations familiales porte sur l’aide à l’investissement. Au-delà de ce coeur commun, les politiques brésiliennes ont plus spécifiquement développé des approches au niveau des territoires locaux et associent plus fortement qu’au Maroc les organisations professionnelles agricoles représentant l’agriculture familiale dans la conception de l’action publique. La comparaison des politiques agricoles au Maroc et au Brésil sur quelques éléments permet de souligner la forte étendue des choix qu’il est possible de considérer, pour définir des

    Low rates of maternal healthcare service utilization, including facility delivery, may impede progress in the prevention of mother-to-child transmission of HIV (PMTCT) and in reducing maternal and infant mortality. The MoMent (Mother Mentor) study investigated the impact of structured peer support on early infant diagnosis presentation and postpartum maternal retention in PMTCT care in rural Nigeria. This paper describes baseline characteristics and correlates of facility delivery among MoMent study participants. HIV-positive pregnant women were recruited at 20 rural Primary Healthcare Centers matched by antenatal care clinic volume, client HIV prevalence, and PMTCT service staffing. Baseline and delivery data were collected by participant interviews and medical record abstraction. Multivariate logistic regression with generalized estimating equation analysis was used to evaluate for correlates of facility delivery including exposure to structured (closely supervised Mentor Mother, intervention) vs unstructured (routine, control) peer support. Of 497 women enrolled, 352 (71%) were between 21 and 30 years old, 319 (64%) were Christian, 245 (49%) had received secondary or higher education, 402 (81%) were multigravidae and 299 (60%) newly HIV-diagnosed. Delivery data was available for 445 (90%) participants, and 276 (62%) of these women delivered at a health facility. Facility delivery did not differ by type of peer support; however, it was positively associated with secondary or greater education (aOR 1.9, CI 1.1-3.2) and Christian affiliation (OR 1.4, CI 1.0-2.0) and negatively associated with primigravidity (OR 0.5; 0.3-0.9) and new HIV diagnosis (OR 0.6, CI 0.4-0.9). Primary-level or lesser-educated HIV-infected pregnant women and those newly-diagnosed and primigravid should be prioritized for interventions to improve facility delivery rates and ultimately, healthy outcomes. Incremental gains in facility delivery from structured peer support appear limited

    2014-06-17

    A system that applies attribute and topology based change detection to networks of objects that were detected on previous scans of a structure, roadway, or area of interest. The attributes capture properties or characteristics of the previously detected objects, such as location, time of detection, size, elongation, orientation, etc. The topology of the network of previously detected objects is maintained in a constellation database that stores attributes of previously detected objects and implicitly captures the geometrical structure of the network. A change detection system detects change by comparing the attributes and topology of new objects detected on the latest scan to the constellation database of previously detected objects.

    Objective: To investigate the value of MRI as imaging technique for lumbosacral spinal nerves before artificial somatic-central nervous system-autonomic reflex pathway establish ment. Methods: Conventional MRI and T 2 W CISS 3D were performed in 10 patients with neurogenic bladder planned for the operation of artificial somatic-central nervous system-autonomic reflex pathway. The Three-dimensional data were then constructed into composite images using a standard multiple planar reformation (MPR). Results: Five patients showed tethered spinal cord syndrome, whose spinal cord nerves were circuitous distributed and had abnormity number when penetrated the dura. Of these 5 patients, one patient was accompanied by spinal cord vas malformation. Four patients had vertebral fracture and spinal injury, and the other one patients demonstrated tumor in vertebral canal on MRI examinations. The spinal cord nerves in these 5 patients floated down river and had normal number of spinal cord nerves. Conclusion: Conventional MRI and T 2 W CISS 3D MRI were essential for the pre-operative planning of artificial somatic-central nervous system-autonomic reflex pathway, especially in patients with tethered spinal cord syndrome. Spinal cord nerves distribute and anterior and posterior roots array can be clearly showed by MPR. (authors)

    HIV continues to be a major concern among MSM, yet Black MSM have not been enrolled in HIV research studies in proportionate numbers to White MSM. We developed an HIV prevention research brand strategy for MSM. Questionnaires and focus groups were conducted with 54 participants. Descriptive statistics and chi-square analyses were performed and qualitative data were transcribed and content analyzed to identify common themes. Formative research results indicated that younger Black MSM (18-29 years) were less likely to think about joining prevention studies compared to older (≥30 years) Black MSM ( x 2 = 5.92, P = 0.015). Qualitative and quantitative results indicate four prominent themes related to brand development: (1) communication sources (message deliverer), (2) message (impact of public health messaging on perceptions of HIV research), (3) intended audience (underlying issues that influence personal relevance of HIV research), and (4) communication channels (reaching intended audiences). The findings highlight the importance of behavioral communication translational research to effectively engage hard-to-reach populations. Despite reservations, MSM in our formative study expressed a need for active involvement and greater education to facilitate their engagement in HIV prevention research. Thus, the brand concept of "InvolveMENt" emerged.

    Full Text Available Nas últimas duas décadas a utilização do termo vulnerabilidade foi expandida para diferentes campos de conhecimento e de intervenção. Neste artigo analisamos o uso da noção de vulnerabilidade no âmbito do sistema socioeducativo como um componente das relações de poder entre instituições de execução de medidas socioeducativas e jovens atendidos. Baseado em pesquisa etnográfica realizada na Região Metropolitana de São Paulo em 2009, 2010 e 2011, com a participação de 14 adolescentes em cumprimento de medidas socioeducativas, o texto analisa o conflito entre o relatório psicológico de um jovem e sua própria interpretação ao falar sobre os mesmos aspectos de sua vida. Discute também como o jovem, intrincado diferentemente por códigos distintos, enseja em sua própria existência conflitos simbólicos que têm escapado às práticas do sistema socioeducativo. O encontro da ideia de vulnerabilidade no relatório psicológico com a perspectiva da mente como atributo de um jovem configura-se um campo de disputas simbólicas entre visões da capacidade de autorregulação do indivíduo.

    The true prevalence of allergic contact dermatitis (ACD) in children remains unknown. Our aim was to compare the results of patch tests in children with suspected ACD between two different periods of time and identify possible changes in emerging allergens. We compared contact allergens, gender, age distribution, and personal history of atopic dermatitis (AD), in correlation with the positivity of patch tests, between two equal periods of time (232 children tested during 1980-1993, period A, and 255 children during 1994-2007, period B) in the same region and in the same institution. Patch test positivity was 47.8% in period A, and 60% in period B (p = 0.083). The most common allergens in period A were: nickel sulfate (16.3%), cobalt chloride (8.6%), fragrance mix (7.3%), potassium dichromate (4.3%), and thimerosal only (1.7%). In period B, the allergen distribution was as follows: nickel sulfate (21.56%), thimerosal (18.03%), cobalt chloride (12.9%), potassium dichromate (9.4%), and fragrance mix (4.7%). Girls were more likely to have a positive patch test compared with boys, with reactions in 53% of girls and 39% of boys in period A (p = 0.003), and 61% of girls and 58% of boys in period B (p = 0.691). Twenty-nine per cent of patients with positive results had a personal history of AD in period A and 44% in period B (p = 0.015). Differences in the positivity of allergens between different time periods reflect changes in habits, of allergens exposure or preventive measures.

    The development of leadership and project management skills is increasingly important to the evolution of translational science and team-based endeavors. Team science is dependent upon individuals at various stages in their careers, inclusive of postdocs. Data from case histories, as well as from interviews with current and former postdocs, and those supervising postdocs, indicate six essential tasks required of project managers in multidisciplinary translational teams, along with eight skill-related themes critical to their success. To optimize the opportunities available and to ensure sequential development of team project management skills, a life cycle model for the development of translational team skills is proposed, ranging from graduate trainees, postdocs, assistant professors, and finally to mature scientists. Specific goals, challenges and project management roles and tasks are recommended for each stage for the life cycle. PMID:25621288

  9. How Clark's nutcrackers (Nucifraga columbiana) weigh geometric cues depends on their previous experience.

    Reichert, James F; Kelly, Debbie M

    2015-07-01

    Following passive disorientation, Clark's nutcrackers (Nucifraga columbiana) learned to search for a hidden food reward located in one corner of a rectangular-shaped enclosure that contained either identical or distinct features in each corner. Identical features allowed for explicit learning of geometric cues, whereas distinct features allowed for both explicit learning of featural cues and incidental learning of geometric cues. Birds that only learned about geometry incidentally (group Distinct) weighed features greater than geometry when the two cues were placed in conflict. However, birds that received explicit training with geometry, in addition to feature training (groups Distinct-Identical and Identical-Distinct), weighed geometry heavier relative to features. Cue preference by the birds also depended on the order in which learning was experienced; if explicit training with geometry followed that of features (group Distinct-Identical), then both geometry and features were weighed equally, but if explicit training with geometry training preceded that of features (group Identical-Distinct), the birds weighed geometry greater than features. Results suggest both a heightened sensitivity to geometric cues by Clark's nutcrackers relative to other species of birds and an increased sensitivity to any spatial cue (either features or geometry) that has proven both stable and reliable.

    The main purpose of this study was to investigate the relationship between interrogative suggestibility and previous convictions among 108 defendants in criminal trials, using a path analysis technique. It was hypothesized that previous convictions, which may provide defendants with interrogative experiences, would correlate negatively with 'shift' as measured by the Gudjonsson Suggestibility Scale (Gudjonsson, 1984a), after intelligence and memory had been controlled for. The hypothesis was partially confirmed and the theoretical and practical implications of the findings are discussed.

    The most common surgical approach in case of local tumor recurrence after quadrantectomy and radiotherapy is salvage mastectomy. Breast reconstruction is the subsequent phase of the treatment and the plastic surgeon has to operate on previously irradiated and manipulated tissues. The medical literature highlights that breast reconstruction with tissue expanders is not a pursuable option, considering previous radiotherapy a contraindication. The purpose of this retrospective study is to evaluate the influence of previous radiotherapy on 2-stage breast reconstruction (tissue expander/implant). Only patients with analogous timing of radiation therapy and the same demolitive and reconstructive procedures were recruited. The results of this study prove that, after salvage mastectomy in previously irradiated patients, implant reconstruction is still possible. Further comparative studies are, of course, advisable to draw any conclusion on the possibility to perform implant reconstruction in previously irradiated patients.

  20. No discrimination against previous mates in a sexually cannibalistic spider

    2005-09-01

    In several animal species, females discriminate against previous mates in subsequent mating decisions, increasing the potential for multiple paternity. In spiders, female choice may take the form of selective sexual cannibalism, which has been shown to bias paternity in favor of particular males. If cannibalistic attacks function to restrict a male's paternity, females may have little interest to remate with males having survived such an attack. We therefore studied the possibility of female discrimination against previous mates in sexually cannibalistic Argiope bruennichi, where females almost always attack their mate at the onset of copulation. We compared mating latency and copulation duration of males having experienced a previous copulation either with the same or with a different female, but found no evidence for discrimination against previous mates. However, males copulated significantly shorter when inserting into a used, compared to a previously unused, genital pore of the female.

    Female sterilization is one of the most common contraceptive methods. A small number of women, however, opt for reversal of sterilization procedures after they experience regret. Procedures can be performed by laparotomy or laparoscopy, with or without robotic assistance. Another commonly utilized alternative is IVF. The choice between surgery and IVF is often influenced by reimbursement politics for that particular geographic location. We evaluated the fertility outcomes of different surgical methods available for the reversal of female sterilization, compared these to IVF and assessed the prognostic factors for success. Two search strategies were employed. Firstly, we searched for randomized and non-randomized clinical studies presenting fertility outcomes of sterilization reversal up to July 2016. Data on the following outcomes were collected: pregnancy rate, ectopic pregnancy rate, cost of the procedure and operative time. Eligible study designs included prospective or retrospective studies, randomized controlled trials, cohort studies, case-control studies and case series. No age restriction was applied. Exclusion criteria were patients suffering from tubal infertility from any other reason (e.g. infection, endometriosis and adhesions from previous surgery) and studies including sterilization reversal procedures were then evaluated: female age, BMI and duration and method of sterilization. Secondly, we searched for randomized and non-randomized clinical studies that compared reversal of sterilization to IVF and evaluated them for pregnancy outcomes and cost effectiveness. We included 37 studies that investigated a total of 10 689 women. No randomized controlled trials were found. Most studies were retrospective cohort studies of a moderate quality. The pooled pregnancy rate after sterilization reversal was 42-69%, with heterogeneity seen from the different methods utilized. The reported ectopic pregnancy rate was 4-8%. The only prognostic factor affecting the

    Full Text Available Au Maroc, les subventions accordées par l’Etat constituent une forte incitation pour que les agriculteurs installent l’irrigation localisée. Cependant le rythme de reconversion est faible dans les périmètres de petite et moyenne hydraulique. Bien que la pertinence d’une reconversion collective des exploitations dans ces périmètres soit souvent reconnue, les superficies converties restent limitées. Malgré quelques tentatives dans le cadre d’expériences pilotes, il n’y a pas de démarche stabilisée d’accompagnement par les institutions de développement d’une telle reconversion collective. Le présent article propose des éléments pour une démarche d’accompagnement à la maturation des projets collectifs à l’irrigation localisée. Cette démarche a été conçue à partir de l’analyse a posteriori de plusieurs expériences de reconversion collective à l’irrigation localisée au Maroc. Cette démarche s’appuie sur l’utilisation d’une grille qui permet de diagnostiquer l’état initial de maturation du projet, mais aussi de suivre l’évolution de cette maturation. L’évaluation de ce niveau de maturation se fait suivant une liste de facteurs qualifiés d’essentiels, d’accélération et de stabilisation. Sont aussi proposés quelques principes et étapes qui pourraient structurer un accompagnement de ces projets.

    Dans la présente étude, nous nous sommes intéressés à la recherche des meilleures conditions de synthèse du composé Bi0,5Sb1,5Te3, présentant des propriétés thermoélectriques optimales à température ambiante pour un composé de type p. Une étude voltampérométrique a donc été menée pour les binaires engageant ces trois éléments, c’est-à-dire Bi-Te et Sb-Te, ainsi que pour le ternaire Bi-Sb-Te. Les ions BiIII+, SbIII+ et TeIV+ ont été mis en solution dans l’électrolyte acide perchlorique HClO4 1M acide tartrique C4H6O6 0,1M, avec une concentration maximale en tellure de l’ordre de 10-2M. Les rapports envisagés entre les ions, choisis en fonction d’études antérieures, sont les suivants : Bi/Te=1 et Sb/Te=1 pour les binaires, et (Bi+Sb)/Te=1 et Sb/Bi=3 pour le ternaire. Des dépôts ont été réalisés à différents potentiels, de manière à identifier les pics obtenus sur les voltampérogrammes. Ces dépôts ont été caractérisés par diffraction des rayons X, et leur stoechiométrie a été obtenue par microsonde de Castaing.

    Full Text Available Practical use of management in sports goes back to the classical period, when gladiator fights accompanied by large number of spectators, were held. During 11th century The Olimpic games were opened with a magnificent ceremonies and included a lot of competition observed by a large crowd. Such large manifestations required: organised catering, promoters and numerous staff responsible for equipment and organisation of the whole event. Beside numerous definitions used in theory and practice, e.i. administration in sports, administration of athletes etc., the term ''management in sports'' is the only one that gives the global view of social reality and its full and the most precise explanation. It includes all activities and services in connection with: sport premises, equipment, location of event, hotels, trade of sport gear, physical culture, recreation and profesional sports.

  8. Prácticas rituales y desapego del mundo: una exploración etnográfica sobre los modos en que los grupos Sai Baba controlan la mente

    Rodolfo Puglisi

    2014-12-01

    Full Text Available Este artículo comienza examinando la concepción que los grupos Sai Baba tienen sobre la mente, argumentando a continuación que sus performances rituales constituyen “tecnologías del yo”, en términos foucaultianos, diseñadas para aquietar la movilidad mental y adquirir una actitud subjetiva consistente en “dejar que las cosas pasen”. Posteriormente, se explica que los devotos se esfuerzan por aplicar esta actitud a la vida cotidiana en tanto lo “mundano” es considerado un producto ilusorio de la mente que nos desvía del camino espiritual. En este punto trataremos el clásico tema weberiano de la “actitud ante el mundo” y cómo éste se manifiesta entre los grupos Sai, especialmente en lo que respecta al desapego y el ascetismo. Finalmente, se concluye que las performances rituales y el desapego de lo mundano son las facetas sagrada y profana, respectivamente, de una estrategia general para “matar” la mente puesta en juego por los devotos Sai.

    To determine the maternal and perinatal outcomes at term in women with one previous cesarean delivery and with no history of vaginal birth. This is a case-control study conducted at King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia, between January 1, 1999 and December 31, 2002. One hundred sixty-two women with one previous cesarean delivery and with no previous vaginal birth were compared with 324 control women. The cesarean section rate was higher in the study group 40 (24.7%) versus 23 (7.1%) in the control group and was statistically significant (phistory of vaginal delivery are considered less favorable, the vaginal birth after cesarean section success rate may be even lower if the indication for previous primary cesarean delivery was failure to progress, and may be associated with increased risk of uterine rupture. Further study is required to confirm our findings.

A retrospective analysis of 3 283 cases of gynecological diseases by laparoscopic operation patients in Peking University First Hospital from 2007 January to 2012 December, among them, 719 (21.90%) patients with previous abdominopelvic surgery history (study Group), 2 564 (78.10%)patients have no history of abdominopelvic surgery (control group). Study group 719 patients, previous operation times: one time in 525 cases, 194 cases were multiple; previous operation: 185 cases of gynecological surgery, 305 cases of obstetric surgery, 108 cases of general surgery, and 121 complex surgery (include at least two kinds of surgery); previous operative approach: 650 cases laparotomy and 69 cases laparoscopy. Compared two groups of patients with abdominopelvic adhesion and the gynecologic laparoscopic operation situation, analyzed the influence of previous abdominopelvic surgery on abdominopelvic adhesion on and gynecological laparoscopic operation. The incidence of abdominopelvic adhesion in the patients with previous abdominopelvic surgery was 51.2% (368/719), which was significantly higher than that of 8.2% (211/2 564)in patients without previous abdominopelvic surgery (P surgery (23.1%, 166/719) was significantly higher than that in the control group (3.3% , 85/2 564;P laparotomy was 0.6% (4/719) significantly more than the control groups (0.1%, 2/2 564; P = 0.023). Compared with other groups, patients with gynecological or complex surgery or multiple operation history presented more severe abdominopelvic adhesion both in the score and degree (P laparotomy showed no statistical difference between the two groups (P > 0.05). The laparoscopic operation could be carried out successfully and safely in patients with a history of various abdominopelvic operations, but the conversion rate increases, for patients with a history of multiple operation because of pelvic adhesion

    2011-01-01

    Secondary recurrent miscarriage (RM) is defined as three or more consecutive pregnancy losses after delivery of a viable infant. Previous reports suggest that a firstborn male child is associated with less favourable subsequent reproductive potential, possibly due to maternal immunisation against male-specific minor histocompatibility antigens. In a retrospective cohort study of 85 cases of secondary RM we aimed to determine if secondary RM was associated with (i) gender of previous child, maternal age, or duration of miscarriage history, and (ii) increased risk of pregnancy complications. Fifty-three women (62.0%; 53\\/85) gave birth to a male child prior to RM compared to 32 (38.0%; 32\\/85) who gave birth to a female child (p=0.002). The majority (91.7%; 78\\/85) had uncomplicated, term deliveries and normal birth weight neonates, with one quarter of the women previously delivered by Caesarean section. All had routine RM investigations and 19.0% (16\\/85) had an abnormal result. Fifty-seven women conceived again and 33.3% (19\\/57) miscarried, but there was no significant difference in failure rates between those with a previous male or female child (13\\/32 vs. 6\\/25, p=0.2). When patients with abnormal results were excluded, or when women with only one previous child were considered, there was still no difference in these rates. A previous male birth may be associated with an increased risk of secondary RM but numbers preclude concluding whether this increases recurrence risk. The suggested association with previous male birth provides a basis for further investigations at a molecular level.

    Cases of renal tubular dysfunction have been reported in patients with hepatitis B and in patients with human immunodeficiency virus who are undergoing tenofovir treatment. However, little is known about the impact on tubular function in patients with chronic hepatitis B (CHB) under long-term use of entecavir (ETV) and tenofovir disoproxil fumarate (TDF). We evaluated markers of renal tubular function and bone turnover in patients with CHB treated with ETV or TDF. A multicenter, cross-sectional study was performed on markers of renal tubular function and bone turnover in hepatitis B virus-monoinfected patients on long-term treatment with Entecavir or Tenofovir (the MENTE study). The analyzed parameters were: retinol-binding protein/creatinine, neutrophil gelatinase-associated lipocalin/creatinine, excretion of phosphates, uric acid excretion, glomerular filtrate, protein/creatinine, albumin/creatinine, serum creatinine, phosphate, CTX, P1NP, vitamin D, and parathormone. A total of 280 patients (ETV: 89, TDF: 69, control: 122) were included in this study. The TDF group was associated with altered levels of retinol-binding protein (RBP)/creatinine (TDF 25% vs. 7% ETV and control; P<0.001). Protein/creatinine, uric acid excretion, P1NP1, and parathormone were higher in the TDF group. The proportion of patients with serum phosphate <2.5 mg/dL was higher in both the ETV and the TDF groups compared with the control. The multivariate analysis showed that the use of TDF was independently associated with a higher risk of altered excretion of RBP/creatinine (4.4; interquartile range: 1.4 to 14; P=0.013). We found an independent association between TDF use and altered RBP excretion. This finding indicates subclinical tubular damage. Because tubular dysfunction can precede the decline of renal function, close monitoring of RBP levels in patients with CHB on nucleos(t)ide analog treatment must be performed for early detection of TDF-related renal toxicity. In this study, these

  19. Artificios del Intelecto: escenarios poshumanos, autopoiesis de la máquina y mentes incorporadas en nuevos paradigmas de inteligencia artificial

    Directory of Open Access Journals (Sweden)

    Alfredo Enrique Rivas

    2013-12-01

    Full Text Available Inicialmente este ensayo establece una base de discusión filosófica sobre la emergencia de la corriente poshumanista utilizando como punto de enfoque el trabajo de Giorgio Agamben y Donna Haraway. Se intenta igualmente observar la constitución de la metáfora mente/computadora, y su importancia y pertinencia en el desarrollo de la psicología copgnoscitiva. La discusión remite a la constitución de un imaginario de inteligencia artificial que utiliza como punto primordial la antropomorfización del procesamiento de información. Se examina la propuesta de Humberto Maturana y Francisco Varela, donde se intenta repensar el estudio de la vida como un proceso continuo de autoorganización. Este modelo ha surgido como una redirección del paradigma de organización biológica, con unas intenciones mucho más inclusivas en términos teóricos de lo que pudiesen ser miradas ortodoxas de la biología. Se intenta retomar el vínculo entre el modelo de autoorganización biológica y su tangencia con la metáfora humano-máquina, constituida bajo la figura del cyborg. Finalmente, se revisan las elaboraciones pertinentes de Jean Baudrillard sobre la cultura del simulacro, y a la idea de un hábitat dominado por procesos de simulación, tal y como se destaca en las publicaciones de Sherry Turkle. Aunque el actual paradigma de estudio y diseño del IA reclame un distanciamiento del paradigma antropomórfico, la ruptura no ha sido total, y por esta razón es necesario observar la forma en que la cultura del simulacro remite a unas instancias de la contemporaneidad que permiten nociones del poshumano, más adecuadas para el diseño de tecnología de alta simulación.

    2014-07-01

    Research has reported that a strong risk factor for traumatic injury is having a previous injury (i.e., recidivism). To date, the only study examining the relationship between recidivism and homicide reported strong associations, but was limited by possible selection bias. The current matched case-control study utilized coroner's data from 2004 to 2008. Subjects were linked to trauma registry data to determine whether the person had a previous traumatic injury. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for the association between homicide and recidivism. Homicide risk was increased for those having a previous traumatic injury (OR 1.81, 95% CI 1.09-2.99) or a previous intentional injury (OR 2.53, 95% CI 1.24-5.17). These results suggest an association between homicide and injury recidivism, and that trauma centers may be an effective setting for screening individuals for secondary prevention efforts of homicide through violence prevention programs. © 2014 American Academy of Forensic Sciences.

    Wolfram syndrome (WFS) is a rare autosomal recessive disease with non-autoimmune childhood onset insulin dependent diabetes and optic atrophy. WFS type 2 (WFS2) differs from WFS type 1 (WFS1) with upper intestinal ulcers, bleeding tendency and the lack ofdiabetes insipidus. Li-fespan is short due to related comorbidities. Only a few familieshave been reported with this syndrome with the CISD2 mutation. Here we report two siblings with a clinical diagnosis of WFS2, previously misdiagnosed with type 1 diabetes mellitus and diabetic retinopathy-related blindness. We report possible additional clinical and laboratory findings that have not been pre-viously reported, such as asymptomatic hypoparathyroidism, osteomalacia, growth hormone (GH) deficiency and hepatomegaly. Even though not a requirement for the diagnosis of WFS2 currently, our case series confirm hypogonadotropic hypogonadism to be also a feature of this syndrome, as reported before. © Polish Society for Pediatric Endocrinology and Diabetology.

    The objective of this study was to evaluate the rates of previously undiagnosed rheumatic diseases during the first trimester of pregnancy and their impact on the pregnancy outcome. Pregnant women in their first trimester were screened using a two-step approach using a self-administered 10-item questionnaire and subsequent testing for rheumatic autoantibodies (antinuclear antibody, anti-double-stranded DNA, anti-extractable nuclear antigen, anticardiolipin antibodies, anti-β2-glycoprotein I antibodies and lupus anticoagulant) and evaluation by a rheumatologist. Overall, the complications of pregnancy evaluated included fetal loss, pre-eclampsia, gestational diabetes, fetal growth restriction, delivery at less than 34 weeks, neonatal resuscitation and admission to the neonatal intensive care unit. Out of the 2458 women screened, the authors identified 62 (2.5%) women with previously undiagnosed undifferentiated connective tissue disease (UCTD) and 24 (0.98%) women with previously undiagnosed definite systemic rheumatic disease. The prevalences were seven (0.28%) for systemic lupus erythematosus and Sjogren's syndrome, six (0.24%) for rheumatoid arthritis, three (0.12%) for antiphospholipid syndrome and one (0.04%) for systemic sclerosis. In multiple exact logistic regression, after adjustment for potential confounders, the OR of overall complications of pregnancy were 2.81 (95% CI 1.29 to 6.18) in women with UCTD and 4.57 (95% CI 1.57 to 13.57) in those with definite diseases, respectively, compared with asymptomatic controls. In our population approximately 2.5% and 1% of first trimester pregnant women had a previously undiagnosed UCTD and definite systemic rheumatic disease, respectively. These conditions were associated with significant negative effects on the outcome of pregnancy.

    This study builds on previous work by Kendall, Leonard, and McKenzie, which investigated event sequence variability for 12 paired events during swallowing by healthy volunteers. They identified four event pairs that always occurred in a stereotyped order and a most common occurring overall order of events during swallowing. In the current study, we investigated overall event sequencing and the same four paired events in a sample of swallows by healthy young (under 45 years old) volunteers. Data were collected during a 16-swallow lateral videofluoroscopy protocol, which included manipulations of bolus volume, barium density, bolus viscosity, and swallow cueing. Our results agreed with previous findings that variable event sequencing is found in healthy swallowing, and, in regard to obligatory sequencing of two paired events, movement of the arytenoids toward the base of the epiglottis begins prior to upper esophageal sphincter (UES) opening and maximum hyolaryngeal approximation occurs after UES opening. However, our data failed to replicate the previous findings that there is obligatory sequencing of maximum pharyngeal constriction after maximal UES distension and the UES opens before bolus arrival at the UES. The most common observed overall event sequence reported by Kendall et al. was observed in only 4/293 swallows in our dataset. Manipulations of bolus volume, bolus viscosity, barium concentration, swallow cueing, and swallow repetitions could not completely account for the differences observed between the two studies.

    Background and Objectives: The aim of this study is to evaluate the prevalence of intraabdominal adhesions to the umbilicus following gynecologic laparoscopy through an umbilical incision. Methods: A retrospective review was performed of all gynecologic laparoscopic procedures in a private practice setting to identify patients with a repeat laparoscopy who had a history of a previous laparoscopy through an umbilical incision. Patients with a history of other surgeries were excluded. All repeat laparoscopies used a left upper quadrant entry technique where the abdominal cavity was surveyed for adhesions. We also reviewed adverse events attributable to the left upper quadrant entry approach. Results: We identified 151 patients who underwent a second laparoscopy and had a previous umbilical scar. Thirty-two of the 151 (21.2%) patients with a history of a laparoscopy had evidence of adhesions to the umbilical undersurface. No adverse events or injuries were attributed to the left upper quadrant entry technique. Conclusions: Adhesions to the umbilical undersurface occur in 21.2% of patients who have undergone a prior laparoscopy through an umbilical incision. For this reason, we recommend an alternate location for entry in patients with an umbilical scar from a previous laparoscopy. PMID:17651555

    In this study we use the maximum overlap discrete packet transform (MODWPT) to investigate residual effects on wheat biomass of fertigation treatments applied to a previous crop. The wheat crop covered nine subplots from a previous experiment on melon response to fertigation. Each subplot had previously received a different level of applied nitrogen. Many factors affect wheat biomass, causing it to vary at different spatial frequencies. We hypothesize that these will include residual effects from fertilizer application (at relatively low spatial frequencies) and the local influence of individual plants from the previous melon crop (at high frequency). To test this hypothesis we use the MODWPT to identify the dominant spatial frequencies of wheat biomass variation, and analyse the relationship to both the previous fertilizer application and the location of individual melon plants in the previous crop. The MODWPT is particularly appropriate for this because it allows us first to identify the key spatial frequencies in the wheat biomass objectively and to analyse them, and their relationship to hypothesized driving factors without any assumptions of uniformity (stationarity) of wheat-biomass variation. The results showed that the applied nitrogen dominated the wheat biomass response, and that there was a noticeable component of wheat-biomass variation at the spatial frequency that corresponds to the melon cropping. We expected wheat biomass to be negatively correlated with the position of melons in the previous crop, due to uptake of the applied nitrogen. The MODWPT, which allows us to detect changes in correlation between variables at different frequencies, showed that such a relationship was found across part of the experiment but not uniformly.

    Full Text Available BACKGROUND: Theory of mind (ToM is a field of social cognition that deals with the individual’s cognitive ability to interpret or infer the mental states of others based on previous knowledge. Recently, research has shown that this ability is compromised in patients with some psychopathologies, e.g., schizophrenia and autistic disorder. Investigators have also shown that deficits in ToM have impacts on social functioning and, consequently, on quality of life. Even though ToM studies have recently grown in number, some problems still remain (e.g., the difficulty of standardized tools to assess ToM in different languages. OBJECTIVES: To describe the translation and adaptation into Brazilian Portuguese of two of the most important and widely used ToM tasks, namely, the Theory of Mind Stories and the Hinting Task. METHOD: The process included the following steps: 1 translation; 2 production of a single translated version and review by specialists; 3 back-translation into English; 4 review by an English-speaking specialist; 5 adaptation of marked corrections; and 6 pilot application in a group representative of the target population (people with schizophrenia. RESULTS: A final translated version was obtained for each of the tasks. Both instruments were well understood by participants and can now be used in the Brazilian experimental setting. CONCLUSION: The availability of two major ToM tasks in Brazilian Portuguese facilitates the conduction of research on the topic in Brazil. In the future, this could help design clinical interventions aimed at people with social and cognitive difficulties.INTRODUÇÃO: A teoria da mente (theory of mind, ToM é um domínio da cognição social que se refere à habilidade cognitiva de interpretar ou inferir estados mentais de outras pessoas através de conhecimentos prévios.

    A design-optimization method for hydraulic machinery is proposed. Optimal designs are obtained using the appropriate CFD evaluation software driven by an evolutionary algorithm which is also assisted by artificial neural networks used as surrogate evaluation models or metamodels. As shown in a previous IAHR paper by the same authors, such an optimization method substantially reduces the CPU cost, since the metamodels can discard numerous non-promising candidate solutions generated during the evolution, at almost negligible CPU cost, without evaluating them by means of the costly CFD tool. The present paper extends the optimization method of the previous paper by making it capable to accommodate and exploit pieces of useful information archived during previous relevant successful designs. So, instead of parameterizing the geometry of the hydraulic machine components, which inevitably leads to many design variables, enough to slow down the design procedure, in the proposed method all new designs are expressed as weighted combinations of the archived ones. The archived designs act as the design space bases. The role of the optimization algorithms is to find the set (or sets, for more than one objectives, where the Pareto front of non-dominated solutions is sought) of weight values, corresponding to the hydraulic machine configuration(s) with optimal performance. Since the number of weights is much less that the number of design variables of the conventional shape parameterization, the design space dimension reduces and the CPU cost of the metamodel-assisted evolutionary algorithm is much lower. The design of a Francis runner is used to demonstrate the capabilities of the proposed method.

    Protothecosis is an uncommon condition resulting from infection by achlorophyllous algae of the Prototheca species. Immunocompromised individuals are generally most susceptible to protothecal infection and tend to develop severe and disseminated disease. However, the association between protothecosis and HIV-induced immunosuppression is not clear, with only a handful of cases having been described to date. Here we report a case of cutaneous protothecosis in a Chinese man with previously undiagnosed HIV infection that responded well to oral itraconazole. © 2014 The Australasian College of Dermatologists.

    Members of the genus Vibrio include many pathogens of humans and marine animals that share genetic information via horizontal gene transfer. Hence, the Vibrio pan-genome carries the potential to establish new pathogenic strains by sharing virulence determinants, many of which have yet to be characterized. Here, we investigated the virulence properties of Vibrio proteolyticus, a Gram-negative marine bacterium previously identified as part of the Vibrio consortium isolated from diseased corals. We found that V. proteolyticus causes actin cytoskeleton rearrangements followed by cell lysis in HeLa cells in a contact-independent manner. In search of the responsible virulence factor involved, we determined the V. proteolyticus secretome. This proteomics approach revealed various putative virulence factors, including active type VI secretion systems and effectors with virulence toxin domains; however, these type VI secretion systems were not responsible for the observed cytotoxic effects. Further examination of the V. proteolyticus secretome led us to hypothesize and subsequently demonstrate that a secreted hemolysin, belonging to a previously uncharacterized clan of the leukocidin superfamily, was the toxin responsible for the V. proteolyticus-mediated cytotoxicity in both HeLa cells and macrophages. Clearly, there remains an armory of yet-to-be-discovered virulence factors in the Vibrio pan-genome that will undoubtedly provide a wealth of knowledge on how a pathogen can manipulate host cells. The pan-genome of the genus Vibrio is a potential reservoir of unidentified toxins that can provide insight into how members of this genus have successfully risen as emerging pathogens worldwide. We focused on Vibrio proteolyticus, a marine bacterium that was previously implicated in virulence toward marine animals, and characterized its interaction with eukaryotic cells. We found that this bacterium causes actin cytoskeleton rearrangements and leads to cell death. Using a

    Full Text Available Heart Transplantation (HTx to date remains the most effective and radical method of treatment of patients with end-stage heart failure. The defi cit of donor hearts is forcing to resort increasingly to the use of different longterm mechanical circulatory support systems, including as a «bridge» to the follow-up HTx. According to the ISHLT Registry the number of recipients underwent cardiopulmonary bypass surgery increased from 40% in the period from 2004 to 2008 to 49.6% for the period from 2009 to 2015. HTx performed in repeated patients, on the one hand, involves considerable technical diffi culties and high risks; on the other hand, there is often no alternative medical intervention to HTx, and if not dictated by absolute contradictions the denial of the surgery is equivalent to 100% mortality. This review summarizes the results of a number of published studies aimed at understanding the immediate and late results of HTx in patients, previously underwent open heart surgery. The effect of resternotomy during HTx and that of the specifi c features associated with its implementation in recipients previously operated on open heart, and its effects on the immediate and long-term survival were considered in this review. Results of studies analyzing the risk factors for perioperative complications in repeated recipients were also demonstrated. Separately, HTx risks after implantation of prolonged mechanical circulatory support systems were examined. The literature does not allow to clearly defi ning the impact factor of earlier performed open heart surgery on the course of perioperative period and on the prognosis of survival in recipients who underwent HTx. On the other hand, subject to the regular fl ow of HTx and the perioperative period the risks in this clinical situation are justifi ed as a long-term prognosis of recipients previously conducted open heart surgery and are comparable to those of patients who underwent primary HTx.

    (1) Linear regression was used to relate snow accumulation during single and consecutive winters with white-tailed deer (Odocoileus virginianus) fawn:doe ratios, mosse (Alces alces) twinning rates and calf:cow ratios, and annual changes in deer and moose populations. Significant relationships were found between snow accumulation during individual winters and these dependent variables during the following year. However, the strongest relationships were between the dependent variables and the sums of the snow accumulations over the previous three winters. The percentage of the variability explained was 36 to 51. (2) Significant relationships were also found between winter vulnerability of moose calves and the sum of the snow accumulations in the current, and up to seven previous, winters, with about 49% of the variability explained. (3) No relationship was found between wolf numbers and the above dependent variables. (4) These relationships imply that winter influences on maternal nutrition can accumulate for several years and that this cumulative effect strongly determines fecundity and/or calf and fawn survivability. Although wolf (Canis lupus L.) predation is the main direct mortality agent on fawns and calves, wolf density itself appears to be secondary to winter weather in influencing the deer and moose populations.

    Full Text Available ABSTRACT: Introduction & Objective: Chemical gas weapons especially nitrogen mustard which was used in Iraq-Iran war against Iranian troops have several harmful effects on skin. Some other chemical agents also can cause acne form lesions on skin. The purpose of this study was to compare the incidence of acneform in previously chemically damaged soldiers and non chemically damaged persons. Materials & Methods: In this descriptive and analytical study, 180 chemically damaged soldiers, who have been referred to dermatology clinic between 2000 – 2004, and forty non-chemically damaged people, were chosen randomly and examined for acneform lesions. SPSS software was used for statistic analysis of the data. Results: The mean age of the experimental group was 37.5 ± 5.2 and that of the control group was 38.7 ± 5.9 years. The mean percentage of chemical damage in cases was 31 percent and the time after the chemical damage was 15.2 ± 1.1 years. Ninety seven cases (53.9 percent of the subjects and 19 people (47.5 percent of the control group had some degree of acne. No significant correlation was found in incidence, degree of lesions, site of lesions and age of subjects between two groups. No significant correlation was noted between percentage of chemical damage and incidence and degree of lesions in case group. Conclusion: Incidence of acneform lesions among previously chemically injured peoples was not higher than the normal cases.

    Full Text Available An unaware event referred to as kidnapping makes the estimation result of localization incorrect. In a previous unknown environment, incorrect localization result causes incorrect mapping result in Simultaneous Localization and Mapping (SLAM by kidnapping. In this situation, the explored area and unexplored area are divided to make the kidnapping recovery difficult. To provide sufficient information on kidnapping, a framework to judge whether kidnapping has occurred and to identify the type of kidnapping with filter-based SLAM is proposed. The framework is called double kidnapping detection and recognition (DKDR by performing two checks before and after the “update” process with different metrics in real time. To explain one of the principles of DKDR, we describe a property of filter-based SLAM that corrects the mapping result of the environment using the current observations after the “update” process. Two classical filter-based SLAM algorithms, Extend Kalman Filter (EKF SLAM and Particle Filter (PF SLAM, are modified to show that DKDR can be simply and widely applied in existing filter-based SLAM algorithms. Furthermore, a technique to determine the adapted thresholds of metrics in real time without previous data is presented. Both simulated and experimental results demonstrate the validity and accuracy of the proposed method.

    The aim of this study was to examine the results of vaginal delivery in patients with a past history of cesarean section. The type of delivery, interventions during delivery, and the prognoses of the mothers and babies were examined in 145 women with a history of cesarean section over the 10-year period from January 2000 to December 2009. A scheduled cesarean section was performed in 27 cases. Vaginal delivery was recommended in 118 cases and the success rate was 94.9% (112/118). Uterine rupture was observed in one patient who experienced a natural rupture at home and whose previous cesarean section was an inverse T incision. No cases required a blood transfusion or hysterectomy. The prognoses of both mothers and babies were good and the vaginal delivery success rate was 94.9%. Uterine rupture was observed in one case. Vaginal delivery with previous cesarean section should be considered in cases with expectation and informed consent. © 2011 The Authors.

    A total of 529 homeless adults in Los Angeles County were surveyed to determine the relationship between their previous use of mental health services and their physical health status, utilization of medical services, personal habits affecting health, experience of injury and victimization, and perceived needs. Homeless adults with a previous psychiatric hospitalization were more likely to have experienced serious physical symptoms during the previous month than those who had used only outpatient mental health services or who had never used mental health services. They reported more reasons for not obtaining needed medical care, were more likely to obtained food from garbage cans, and had the least adequate personal hygiene. However, they did not differ from the other groups on most measures of nutrition, social relations, and financial status. The most frequently expressed needs of the homeless were for improved social relations, employment, shelter, and money.

    1996-06-01

    The process of clerking routine pre-operative admissions involves the house officer taking a full medical history and performing a full physical examination. The diagnostic yield is thought to be low, and the educational value to the house officer is also small. This study addresses the question as to whether routine physical examination is always indicated. One hundred and nine children admitted for routine Otolaryngology procedures were prospectively studied to identify the importance of examination in the pre-operative assessment of patients. The results showed that 51 per cent of the children admitted had risk factors. The medical history was sufficient to identify these risk factors in all patients with the exception of one cardiac condition. This study concludes that a suitable alternative to the current process of clerking such as a standardized nurse history could be safely and efficiently undertaken. Eliminating the tiny percentage of previously unrecognized disease would be a prerequisite for such a change.

    Establishment of a percutaneous endoscopic jejunostomy via direct jejunal puncture was accomplished in a 45-year-old woman five years after a partial esophagectomy with cervical esophagogastrostomy for adenocarcinoma of the esophagus. The patient had recurrence of the cancer at the anastomotic site with subsequent inability to eat, necessitating a feeding tube for prolonged enteral nutrition. Although percutaneous puncture of the jejunum has been previously described, it has been limited to patients who had undergone partial or complete gastrectomies with Bilroth II anastomoses. This case report of direct endoscopic jejunal tube placement in a patient after esophagectomy further establishes this procedure as a viable alternative to surgically placed feeding tubes in patients with altered gastric anatomy.

    The incidence of breast cancer is increasing each year. Concomitantly, cosmetic breast augmentation has become the second most often performed cosmetic surgical procedure. As the augmented patient population ages, an increasing number of breast cancer cases among previously augmented women can be anticipated. The surgical treatment of these patients is controversial, with several questions remaining unanswered. Is breast conservation therapy feasible in this patient population and can these patients retain their implants? A retrospective review of all breast cancer patients with a history of previous augmentation mammaplasty who were treated at the Revlon/UCLA Breast Center between 1991 and 2001 was performed. During the study period, 58 patients were treated. Thirty patients (52 percent) were treated with a modified radical mastectomy with implant removal. Twenty-eight patients (48 percent) underwent breast conservation therapy, which consisted of lumpectomy, axillary lymph node dissection, and radiotherapy. Twenty-two of the patients who underwent breast conservation therapy initially retained their implants. Eleven of those 22 patients (50 percent) ultimately required completion mastectomies with implant removal because of implant complications (two patients), local recurrences (five patients), or the inability to obtain negative margins (four patients). Nine additional patients experienced complications resulting from their implants, including contracture, erosion, pain, and rupture. The data illustrate that breast conservation therapy with maintenance of the implant is not ideal for the majority of augmented patients. Breast conservation therapy with explantation and mastopexy might be appropriate for rare patients with large volumes of native breast tissue. Mastectomy with immediate reconstruction might be a more suitable choice for these patients.

    The objective was to compare contraceptive method selection in women undergoing their first pregnancy termination versus women undergoing repeat pregnancy termination in an urban abortion clinic. We hypothesized that women undergoing repeat abortions will select highly effective contraceptives (intrauterine device, subdermal implant, tubal ligation) more often than patients undergoing their first abortion. We conducted a retrospective analysis of all women undergoing first-trimester surgical abortion at John H. Stroger, Jr., Hospital of Cook County from October 1, 2009, to October 31, 2011. We compared contraceptive method selection in the postabortion period after receipt of contraceptive counseling for 7466 women, stratifying women by history of no prior abortion versus one or more abortions. Of the 7466 women, 48.6% (3625) had no history of previous abortion. After controlling for age, race and number of living children, women with a history of abortion were more likely to select a highly effective method [odds ratio (OR) 1.19, 95% confidence interval (CI) 1.06-1.33]. Most significantly, having living children was the strongest predictor of a highly effective method with an OR of 3.17 (95% CI 2.69-3.75). In women having a first-trimester abortion, the factors most predictive of selecting a highly effective method for postabortion contraception include history of previous abortion and having living children. The latter holds true independent of abortion history. This paper is unique in its ability to demonstrate the high interest in highly effective contraceptive selection in high-risk, low-income women with prior abortion history. Efforts to integrate provision of highly effective methods of contraception for postabortion care are essential for the reduction of future unintended pregnancies. Copyright © 2015 Elsevier Inc.

    Fingermarks are a source of human identification both through the ridge patterns and DNA profiling. Typing nuclear STR DNA markers from previously enhanced fingermarks provides an alternative method of utilising the limited fingermark deposit that can be left behind during a criminal act. Dusting with fingerprint powders is a standard method used in classical fingermark enhancement and can affect DNA data. The ability to generate informative DNA profiles from powdered fingerprints using direct PCR swabs was investigated. Direct PCR was used as the opportunity to generate usable DNA profiles after performing any of the standard DNA extraction processes is minimal. Omitting the extraction step will, for many samples, be the key to success if there is limited sample DNA. DNA profiles were generated by direct PCR from 160 fingermarks after treatment with one of the following dactyloscopic fingerprint powders: white hadonite; silver aluminium; HiFi Volcano silk black; or black magnetic fingerprint powder. This was achieved by a combination of an optimised double-swabbing technique and swab media, omission of the extraction step to minimise loss of critical low-template DNA, and additional AmpliTaq Gold ® DNA polymerase to boost the PCR. Ninety eight out of 160 samples (61%) were considered 'up-loadable' to the Australian National Criminal Investigation DNA Database (NCIDD). The method described required a minimum of working steps, equipment and reagents, and was completed within 4h. Direct PCR allows the generation of DNA profiles from enhanced prints without the need to increase PCR cycle numbers beyond manufacturer's recommendations. Particular emphasis was placed on preventing contamination by applying strict protocols and avoiding the use of previously used fingerprint brushes. Based on this extensive survey, the data provided indicate minimal effects of any of these four powders on the chance of obtaining DNA profiles from enhanced fingermarks. Copyright © 2017

    Rationale: Previous respiratory diseases have been associated with increased risk of lung cancer. Respiratory conditions often co-occur and few studies have investigated multiple conditions simultaneously. Objectives: Investigate lung cancer risk associated with chronic bronchitis, emphysema, tuberculosis, pneumonia, and asthma. Methods: The SYNERGY project pooled information on previous respiratory diseases from 12,739 case subjects and 14,945 control subjects from 7 case–control studies conducted in Europe and Canada. Multivariate logistic regression models were used to investigate the relationship between individual diseases adjusting for co-occurring conditions, and patterns of respiratory disease diagnoses and lung cancer. Analyses were stratified by sex, and adjusted for age, center, ever-employed in a high-risk occupation, education, smoking status, cigarette pack-years, and time since quitting smoking. Measurements and Main Results: Chronic bronchitis and emphysema were positively associated with lung cancer, after accounting for other respiratory diseases and smoking (e.g., in men: odds ratio [OR], 1.33; 95% confidence interval [CI], 1.20–1.48 and OR, 1.50; 95% CI, 1.21–1.87, respectively). A positive relationship was observed between lung cancer and pneumonia diagnosed 2 years or less before lung cancer (OR, 3.31; 95% CI, 2.33–4.70 for men), but not longer. Co-occurrence of chronic bronchitis and emphysema and/or pneumonia had a stronger positive association with lung cancer than chronic bronchitis “only.” Asthma had an inverse association with lung cancer, the association being stronger with an asthma diagnosis 5 years or more before lung cancer compared with shorter. Conclusions: Findings from this large international case–control consortium indicate that after accounting for co-occurring respiratory diseases, chronic bronchitis and emphysema continue to have a positive association with lung cancer.

    Full Text Available We conducted two experiments to test whether individuals' strategy choices in a numerosity judgement task are affected by the strategy that was used on the previous trials. Both experiments demonstrated that a previously used strategy indeed influences individuals' strategy choices. Individuals were more inclined to reuse the strategy that they had used on the previous trials. However, this study also demonstrated that this influence is limited to those items that do not have a strong association with a specific strategy. Possible underlying mechanisms for the observed effect are discussed.

    Full Text Available A noção de “concepção” ocupa um lugar central na teoria do conhecimento perceptual de Thomas Reid, embora “concepção” possa ser estudada por si como uma fonte de conhecimento. Neste estudo, procura-se expor sistematicamente os vários contextos em que Reid aborda a fonte de conhecimento e o tipo de operação mental chamada “concepção”. O objetivo é compreender um aspecto específico do desempenho da “concepção” na teoria reidiana da percepção, a saber, uma relação direta, não mediada por ideias, entre o sujeito cognoscente e o mundo exterior. Entender a operação de conceber, intrínseca à e constituinte da percepção, é um meio eficaz de compreender a natureza e o conteúdo do conhecimento perceptual. Nesse passo, considerações sobre a relação mente e mundo exterior, isto é, mente e mundo material precisam ser feitas

    In four experiments we assessed whether visual working memory (VWM) maintains a record of previously processed visual information, allowing old information to be inhibited, and new information to be prioritized. Specifically, we evaluated whether VWM contributes to the inhibition (i.e., visual marking) of previewed distractors in a preview search. We evaluated this proposal by testing three predictions. First, Experiments 1 and 2 demonstrate that preview inhibition is more effective when the number of previewed distractors is below VWM capacity than above; an effect that can only be observed at small preview set sizes (Experiment 2A) and when observers are allowed to move their eyes freely (Experiment 2B). Second, Experiment 3 shows that, when quantified as the number of inhibited distractors, the magnitude of the preview effect is stable across different search difficulties. Third, Experiment 4 demonstrates that individual differences in preview inhibition are correlated with individual differences in VWM capacity. These findings provide converging evidence that VWM supports the inhibition of previewed distractors. More generally, these findings demonstrate how VWM contributes to the efficiency of human visual information processing--VWM prioritizes new information by inhibiting old information from being reselected for attention.

Vychází z předpokladu, že vzdělávání žáků s mentálním postižením by mělo probíhat za podmínek, které v nich evokují libé pocity. A k těmto podmínkám patří i barevnost. Jsou prezentovány výsledky šetření preference barev probandy s lehkým a středně těžkým mentálním postižením. Výsledky naznačují, že probandi s lehkým mentálním postižením mají tendenci citlivě vnímat barvy, a to i v abstraktní podobě. Preferují modrou, případně zelenou a červenou barvu a hůře přijímají černou a fialovou. Preference oblíbené barvy je u probandů s těžším mentálním postižením více variabilní než u probandů s lehkým mentálním postižením. The following article attempts to utilize general knowledge of colours in the sphere of physical culture and applies it to physical education in special schools. It is based on the precondition that education of mentally-handicapped pupils should proceed under conditions evoking pleasurable feelings in them. And such conditions also include colours. The article presents the results of an examination of colour preference in probands with slight to moderate mental handicaps. The results show that probands with a slight mental handicap tend to be sensitive in relation to colours, even in their abstract form. They prefer blue, respectively green and red, and they have difficulties with perception of black and violet. The favourite colour preference in probands with a more serious mental handicap is more variable than in probands with a slight mental handicap.

    Full Text Available Discute-se o problema da relação entre mente e corpo na teoria de Piaget. A relação entre mente e corpo é explicada por Piaget em termos de um paralelismo entre a psique e os processos físicos. Por um lado, o corpo é uma parte integral do mundo de objetos materiais e, como tal, obedece às regras da causalidade. Por outro lado, a mente é uma unidade formal e, como tal, obedece à lei da necessidade formal que é a implicação. Qual a relação entre eles? Todas as formas de conhecimento originam-se da ação sensório-motora. Ações são primeiro somente rítmicas e depois reguladoras. Regulações dão origem a diferentes formas de comportamento de regras e consciência de normas. Essa consciência requer uma distinção entre fatos e normas, causas e significados, assim como a distinção entre corpo e mente. No entanto, os dois pólos desses pares são sempre complementares um em relação ao outro. O princípio de equilibração regula o isomorfismo potencial entre mente e corpo, como seu desenvolvimento em uma espiral geral de conhecimento. O corpo constitui o mediador entre o self e o meio, assim como essa mediação constitui, inversamente, o self ele mesmo.This article discusses the relation between mind and body in Piagetian theory. The relation between mind and body is explained by Piaget in terms of a parallelism between psyche and physical processes. On one side, the body is a part of the world of material objects and, as such, obeys the rules of causality. On the other hand, the mind is a formal unity and, as such, obeys the rule of formal necessity that is implication. What is the relation between both? All forms of knowledge have the origin in sensory-motor actions. Actions are at first rhythmic and afterwards regulatory. Regulations give origin to different forms of rule behavior and norm consciousness. This consciousness requires a distinction between facts and norms, causes and meanings, as well as the distinction

    The relationship between radon anomalies and earthquakes has been studied for more than 30 years. However, most of the studies dealt with radon in soil gas or in groundwater. Before the 1995 Hyogoken-Nanbu earthquake, an anomalous increase of atmospheric radon was observed at Kobe Pharmaceutical University. The increase was well fitted with a mathematical model related to earthquake fault dynamics. This paper reports the significance of this observation, reviewing previous studies on radon anomaly before earthquakes. Groundwater/soil radon measurements for earthquake prediction began in 1970's in Japan as well as foreign countries. One of the most famous studies in Japan is groundwater radon anomaly before the 1978 Izu-Oshima-kinkai earthquake. We have recognized the significance of radon in earthquake prediction research, but recently its limitation was also pointed out. Some researchers are looking for a better indicator for precursors; simultaneous measurements of radon and other gases are new trials in recent studies. Contrary to soil/groundwater radon, we have not paid much attention to atmospheric radon before earthquakes. However, it might be possible to detect precursors in atmospheric radon before a large earthquake. In the next issues, we will discuss the details of the anomalous atmospheric radon data observed before the Hyogoken-Nanbu earthquake. (author)

  18. Cerebral Metastasis from a Previously Undiagnosed Appendiceal Adenocarcinoma

    2012-01-01

    Full Text Available Brain metastases arise in 10%–40% of all cancer patients. Up to one third of the patients do not have previous cancer history. We report a case of a 67-years-old male patient who presented with confusion, tremor, and apraxia. A brain MRI revealed an isolated right temporal lobe lesion. A thorax-abdomen-pelvis CT scan showed no primary lesion. The patient underwent a craniotomy with gross-total resection. Histopathology revealed an intestinal-type adenocarcinoma. A colonoscopy found no primary lesion, but a PET-CT scan showed elevated FDG uptake in the appendiceal nodule. A right hemicolectomy was performed, and the specimen showed a moderately differentiated mucinous appendiceal adenocarcinoma. Whole brain radiotherapy was administrated. A subsequent thorax-abdomen CT scan revealed multiple lung and hepatic metastasis. Seven months later, the patient died of disease progression. In cases of undiagnosed primary lesions, patients present in better general condition, but overall survival does not change. Eventual identification of the primary tumor does not affect survival. PET/CT might be a helpful tool in detecting lesions of the appendiceal region. To the best of our knowledge, such a case was never reported in the literature, and an appendiceal malignancy should be suspected in patients with brain metastasis from an undiagnosed primary tumor.

    Full Text Available The aim of this work is to analyze the influence of study field, expertise and recreational activities participation in Torrance Tests of Creative Thinking (TTCT, 1974 performance. Several hypotheses were postulated to explore the possible effects of previous knowledge in TTCT verbal and TTCT figural university students’ outcomes. Participants in this study included 418 students from five study fields: Psychology;Philosophy and Literature, Music; Engineering; and Journalism and Advertising (Communication Sciences. Results found in this research seem to indicate that there in none influence of the study field, expertise and recreational activities participation in neither of the TTCT tests. Instead, the findings seem to suggest some kind of interaction between certain skills needed to succeed in specific studies fields and performance on creativity tests, such as the TTCT. These results imply that TTCT is a useful and valid instrument to measure creativity and that some cognitive process involved in innovative thinking can be promoted using different intervention programs in schools and universities regardless the students study field.

    An integrative approach was used to obtain pure cultures of previously uncultivated members of the divisions Acidobacteria and Verrucomicrobia from agricultural soil and from the guts of wood-feeding termites. Some elements of the cultivation procedure included the following: the use of agar media with little or no added nutrients; relatively long periods of incubation (more than 30 days); protection of cells from exogenous peroxides; and inclusion of humic acids or a humic acid analogue (anthraquinone disulfonate) and quorum-signaling compounds (acyl homoserine lactones) in growth media. The bacteria were incubated in the presence of air and in hypoxic (1 to 2% O2 [vol/vol]) and anoxic atmospheres. Some bacteria were incubated with elevated concentrations of CO2 (5% [vol/vol]). Significantly more Acidobacteria were found on isolation plates that had been incubated with 5% CO2. A simple, high-throughput, PCR-based surveillance method (plate wash PCR) was developed. This method greatly facilitated detection and ultimate isolation of target bacteria from as many as 1,000 colonies of nontarget microbes growing on the same agar plates. Results illustrate the power of integrating culture methods with molecular techniques to isolate bacteria from phylogenetic groups underrepresented in culture. PMID:15294811

    Full Text Available Measles is caused by measles virus belonging to genus Morbillivirus of the family Paramyxoviridae. Vaccination has played a critical role in controlling measles infection worldwide. However, in the recent years, outbreaks of measles infection still occur in many developing countries. Here, we report an outbreak of measles among healthcare workers and among the 60 measles infected patients 50 were healthcare workers including doctors, nurses, staff, and medics. Fifty-one patients (85% tested positive for IgM antibodies against the measles virus and 50 patients (83.3% tested positive for measles virus RNA. Surprisingly, 73.3% of the infected individuals had been previously immunized against measles. Since there is no infection division in our hospital, the fever clinics are located in the Emergency Division. In addition, the fever and rash were not recognized as measles symptoms at the beginning of the outbreak. These factors result in delay in isolation and early confirmation of the suspected patients and eventually a measles outbreak in the hospital. Our report highlights the importance of following a two-dose measles vaccine program in people including the healthcare workers. In addition, vigilant attention should be paid to medical staff with clinical fever and rash symptoms to avoid a possible nosocomial transmission of measles infection.

    Full Text Available A hybrid coevolution particle swarm optimization algorithm with dynamic multispecies strategy based on K-means clustering and nonrevisit strategy based on Binary Space Partitioning fitness tree (called MCPSO-PSH is proposed. Previous search history memorized into the Binary Space Partitioning fitness tree can effectively restrain the individuals’ revisit phenomenon. The whole population is partitioned into several subspecies and cooperative coevolution is realized by an information communication mechanism between subspecies, which can enhance the global search ability of particles and avoid premature convergence to local optimum. To demonstrate the power of the method, comparisons between the proposed algorithm and state-of-the-art algorithms are grouped into two categories: 10 basic benchmark functions (10-dimensional and 30-dimensional, 10 CEC2005 benchmark functions (30-dimensional, and a real-world problem (multilevel image segmentation problems. Experimental results show that MCPSO-PSH displays a competitive performance compared to the other swarm-based or evolutionary algorithms in terms of solution accuracy and statistical tests.

    Full Text Available Sarcoma development has been associated with genetics, irradiation, viral infections, and immunodeficiency. Reports of sarcomas arising in the setting of prior trauma, as in burn scars or fracture sites, are rare. We report a case of a leiomyosarcoma arising in an arm that had previously been replanted at the level of the elbow joint following traumatic amputation when the patient was eight years old. He presented twenty-four years later with a 10.8 cm mass in the replanted arm located on the volar forearm. The tumor was completely resected and pathology examination showed a high-grade, subfascial spindle cell sarcoma diagnosed as a grade 3 leiomyosarcoma with stage pT2bNxMx. The patient underwent treatment with brachytherapy, reconstruction with a free flap, and subsequently chemotherapy. To the best of our knowledge, this is the first case report of leiomyosarcoma developing in a replanted extremity. Development of leiomyosarcoma in this case could be related to revascularization, scar formation, or chronic injury after replantation. The patient remains healthy without signs of recurrence at three-year follow-up.

    To assess the degree of collateral vessels after myocardial infarction, coronary angiograms, left ventriculograms, and exercise thallium-201 myocardial scintigrams of 36 patients with previous myocardial infarction were reviewed. All 36 patients had total occlusion of infarct-related coronary artery and no more than 70% stenosis in other coronary arteries. In 19 of 36 patients with transient reduction of thallium-201 uptake in the infarcted area during exercise (Group A), good collaterals were observed in 10 patients, intermediate collaterals in 7 patients, and poor collaterals in 2 patients. In 17 of 36 patients without transient reduction of thallium-201 uptake in the infarcted area during exercise (Group B), good collaterals were seen in 2 patients, intermediate collaterals in 7 patients, and poor collaterals in 8 patients (p less than 0.025). Left ventricular contractions in the infarcted area were normal or hypokinetic in 10 patients and akinetic or dyskinetic in 9 patients in Group A. In Group B, 1 patient had hypokinetic contraction and 16 patients had akinetic or dyskinetic contraction (p less than 0.005). Thus, patients with transient reduction of thallium-201 uptake in the infarcted area during exercise had well developed collaterals and preserved left ventricular contraction, compared to those in patients without transient reduction of thallium-201 uptake in the infarcted area during exercise. These results suggest that the presence of viable myocardium in the infarcted area might be related to the degree of collateral vessels

    Academic results depend strongly on the individual circumstances of students: background, motivation and aptitude. We think that academic activities conducted to increase motivation must be tuned to the special situation of the students. Main goal of this work is analyze the students in the first year of the Degree in Optics and Optometry in the University of Granada and the suitability of an activity designed for those students. Initial data were obtained from a survey inquiring about the reasons to choose this degree, their knowledge of it, and previous academic backgrounds. Results show that: 1) the group is quite heterogeneous, since students have very different background. 2) Reasons to choose the Degree in Optics and Optometry are also very different, and in many cases were selected as a second option. 3) Knowledge and motivations about the Degree are in general quite low. Trying to increase the motivation of the students we designed an academic activity in which we show different topics studied in the Degree. Results show that students that have been involved in this activity are the most motivated and most satisfied with their election of the degree.

    To evaluate the role of Bordetella pertussis infection, 96 otherwise healthy 7- to 17-year-old subjects who were suffering from a cough lasting from 2 to 8 weeks were prospectively recruited. At enrolment, a nasopharyngeal swab and an oral fluid sample were obtained to search for pertussis infection by the detection of B. pertussis DNA and/or an elevated titre of anti-pertussis toxin IgG. Evidence of pertussis infection was found in 18 (18.7 %; 95 % confidence interval, 11.5-28.0) cases. In 15 cases, the disease occurred despite booster administration. In two cases, pertussis was diagnosed less than 2 years after the booster injection, whereas in the other cases it was diagnosed between 2 and 9 years after the booster dose. This study used non-invasive testing to show that pertussis is one of the most important causes of long-lasting cough in school-age subjects. Moreover, the protection offered by acellular pertussis vaccines currently wanes more rapidly than previously thought.

    The ecology of mosquito vectors and malaria parasites affect the incidence, seasonal transmission and geographical range of malaria. Most malaria models to date assume constant or linear responses of mosquito and parasite life-history traits to temperature, predicting optimal transmission at 31 °C. These models are at odds with field observations of transmission dating back nearly a century. We build a model with more realistic ecological assumptions about the thermal physiology of insects. Our model, which includes empirically derived nonlinear thermal responses, predicts optimal malaria transmission at 25 °C (6 °C lower than previous models). Moreover, the model predicts that transmission decreases dramatically at temperatures > 28 °C, altering predictions about how climate change will affect malaria. A large data set on malaria transmission risk in Africa validates both the 25 °C optimum and the decline above 28 °C. Using these more accurate nonlinear thermal-response models will aid in understanding the effects of current and future temperature regimes on disease transmission.

    Full Text Available Aim: The changes of the hypothalamic pituitary adrenal (HPA axis response to a long distance transportation results in increase of adrenocorticotropic hormone (ACTH and cortisol levels. The purpose of the study was to quantify the level of short-term road transport stress on circulating ACTH and cortisol concentrations, related to the effect of previous handling and transport experience of horses. Materials and Methods: The study was performed on 56 healthy horses after short-term road transport of 30 km. The horses were divided into four groups, Groups A, B, C, and D, with respect to the handling quality: Good (Groups A and B, bad (Group D, and minimal handling (Group C conditions. According to the previous transport, experience horses were divided as follows: Horses of Groups A and D had been experienced long-distance transportation before; horses of Groups B and C had been limited experience of transportation. Results: One-way RM-ANOVA showed significant effects of transport on ACTH changes in Groups B and C and on cortisol changes in both Groups A and B. Groups A and B showed lower baseline ACTH and cortisol values than Groups C and D; Groups A and B showed lower post-transport ACTH values than Groups C and D. Groups A, B, and C showed lower post-transport cortisol values than Group D. Only Groups A and B horses have shown an adequate capacity of stress response to transportation. Conclusion: The previous transport experience and quality of handling could influence the HPA axis physiological responses of horses after short-term road transport.

    Register data allow for nuanced analyses of heterogeneities between sub-groups which are not observable in other data sources. One heterogeneity for which register data is particularly useful is in identifying unique migration histories of immigrant populations, a group of interest across disciplines. Years since migration is a commonly used measure of integration in studies seeking to understand the outcomes of immigrants. This study constructs detailed migration histories to test whether misclassified migrations may mask important heterogeneities. In doing so, we identify a previously understudied group of migrants called repeat immigrants, and show that they differ systematically from permanent immigrants. In addition, we quantify the degree to which migration information is misreported in the registers. The analysis is carried out in two steps. First, we estimate income trajectories for repeat immigrants and permanent immigrants to understand the degree to which they differ. Second, we test data validity by cross-referencing migration information with changes in income to determine whether there are inconsistencies indicating misreporting. From the first part of the analysis, the results indicate that repeat immigrants systematically differ from permanent immigrants in terms of income trajectories. Furthermore, income trajectories differ based on the way in which years since migration is calculated. The second part of the analysis suggests that misreported migration events, while present, are negligible. Repeat immigrants differ in terms of income trajectories, and may differ in terms of other outcomes as well. Furthermore, this study underlines that Swedish registers provide a reliable data source to analyze groups which are unidentifiable in other data sources.

    Full Text Available : Introduction: Popliteal artery aneurysms (PAAs are rare in the general population, but they account for nearly 70% of peripheral arterial aneurysms. There are several possible surgical approaches including exclusion of the aneurysm and bypass grafting, or endoaneurysmorrhaphy and interposition of a prosthetic conduit. The outcomes following the first approach are favorable, but persistent blood flow in the aneurysm sac has been documented in up to one third of patients in the early post-operative setting. Complications from incompletely excluded aneurysms include aneurysm enlargement, local compression symptoms, and sac rupture. Notably infection of a previously excluded and bypassed PAA is rare. This is the third reported case of PAA infection after exclusion and bypass grafting and the first due to Serratia liquefaciens. Methods: Relevant medical data were collected from the hospital database. Results: This case report describes a 54 year old male patient, diagnosed with acute limb ischaemia due to a thrombosed PAA, submitted to emergency surgery with exclusion and venous bypass. A below the knee amputation was necessary 3 months later. Patient follow-up was lost until 7 years following surgical repair, when he was diagnosed with aneurysm sac infection with skin fistulisation. He had recently been diagnosed with alcoholic hepatic cirrhosis Child–Pugh Class B. The patient was successfully treated by aneurysm resection, soft tissue debridement and systemic antibiotics. Conclusion: PAA infection is a rare complication after exclusion and bypass procedures but should be considered in any patient with evidence of local or systemic infection. When a PAA infection is diagnosed, aneurysmectomy, local debridement, and intravenous antibiotic therapy are recommended. The “gold standard” method of PAA repair remains controversial. PAA excision or endoaneurysmorrhaphy avoids complications from incompletely excluded aneurysms, but is associated with

    Full Text Available Abstract Human astroviruses are a leading cause of gastrointestinal disease. Since their discovery in 1975, 8 closely related serotypes have been described in humans, and more recently, two new astrovirus species, astrovirus MLB1 and astrovirus VA1, were identified in diarrhea patients. In this study, we used consensus astrovirus primers targeting the RNA polymerase to define the diversity of astroviruses present in pediatric patients with diarrhea on two continents. From 416 stool specimens comprising two different cohorts from Vellore, India, 35 samples were positive. These positive samples were analyzed further by either sequencing of the ~400 bp amplicon generated by the consensus PCR or by performing additional RT-PCR specific for individual astroviruses. 19 samples contained the classic human astrovirus serotypes 1-8 while 7 samples were positive for the recently described astrovirus MLB1. Strikingly, from samples that were positive in the consensus PCR screen but negative in the specific PCR assays, five samples contained sequences that were highly divergent from all previously described astroviruses. Sequence analysis suggested that three novel astroviruses, tentatively named astroviruses VA2, MLB2 and VA3, were present in these five patient specimens (AstV-VA2 in 2 patients, AstV-MLB2 in 2 patients and AstV-VA3 in one patient. Using the same RT-PCR screening strategy, 13 samples out of 466 tested stool specimens collected in St. Louis, USA were positive. Nine samples were positive for the classic human astroviruses. One sample was positive for AstV-VA2, and 3 samples were positive for AstV-MLB2 demonstrating that these two viruses are globally widespread. Collectively, these findings underscore the tremendous diversity of astroviruses present in fecal specimens from diarrhea patients. Given that a significant fraction of diarrhea etiologies is currently unknown, it is plausible that these or other yet unrecognized astroviruses may be

    Full Text Available PURPOSE: Sacrococcygeal pilonidal disease is a source of one of the most common surgical problems among young adults. While male gender, obesity, occupations requiring sitting, deep natal clefts, excessive body hair, poor body hygiene and excessive sweating are described as the main risk factors for this disease, most of these need to be verified with a clinical trial. The present study aimed to evaluate the value and effect of these factors on pilonidal disease. METHOD: Previously proposed main risk factors were evaluated in a prospective case control study that included 587 patients with pilonidal disease and 2,780 healthy control patients. RESULTS: Stiffness of body hair, number of baths and time spent seated per day were the three most predictive risk factors. Adjusted odds ratios were 9.23, 6.33 and 4.03, respectively (p<0.001. With an adjusted odds ratio of 1.3 (p<.001, body mass index was another risk factor. Family history was not statistically different between the groups and there was no specific occupation associated with the disease. CONCLUSIONS: Hairy people who sit down for more than six hours a day and those who take a bath two or less times per week are at a 219-fold increased risk for sacrococcygeal pilonidal disease than those without these risk factors. For people with a great deal of hair, there is a greater need for them to clean their intergluteal sulcus. People who engage in work that requires sitting in a seat for long periods of time should choose more comfortable seats and should also try to stand whenever possible.

    Atomic force microscopy (AFM) is a mechanical profiling technique that allows to image surfaces with atomic resolution. Recent progress in reducing the noise of this technique has led to a resolution level where previously undetectable symmetries of the images of single atoms are observed. These symmetries are related to the nature of the interatomic forces. The Si(111)-(7 × 7) surface is studied by AFM with various tips and AFM images are simulated with chemical and electrostatic model forces. The calculation of images from the tip-sample forces is explained in detail and the implications of the imaging parameters are discussed. Because the structure of the Si(111)-(7 × 7) surface is known very well, the shape of the adatom images is used to determine the tip structure. The observability of atomic orbitals by AFM and scanning tunneling microscopy is discussed.

  15. Repetition of previously novel melodies sometimes increases both remember and know responses in recognition memory.

    1996-09-01

    Recognition memory for previously novel melodies was tested in three experiments in which subjects usedremember andknow responses to report experiences of recollection, or of familiarity in the absence of recollection, for each melody they recognized. Some of the melodies were taken from Polish folk songs and presented vocally, but without the words. Others were taken from obscure pieces of classical music, presented as single-line melodies. Prior to the test, the melodies were repeated for varying numbers of study trials. Repetition of the Polish melodies increased both remember and know responses, while repetition of classical melodies increased remember but not know responses. When subjects were instructed to report guesses, guess responses were inversely related to remember and know responses and there were more guesses to lures than to targets. These findings establish that remembering and knowing are fully independent functionally and, by the same token, they provide further evidence against the idea that response exclusivity causes increases in remembering to force decreases in knowing. The findings also suggest that simultaneous increases in remembering and knowing occurred because the Polish melodies came from a genre for which the subjects had relatively little previous experience.

    Full Text Available Este artigo tem por objetivo analisar como a mente se torna social, à luz das idéias de Bruner e frente às idéias de Valsiner. Bruner entende a mente como criadora de significados e busca compreender a interação através da qual a mente constitui e é constituída pela cultura. Propõe uma psicologia interessada na ação e seu caráter situacional, assim como nas formas em que os seres humanos produzem significados nos contextos culturais. As pessoas, para Bruner, são resultado do processo de produção de significados, realizado com o auxílio dos sistemas simbólicos da cultura. O artigo aborda os temas centrais discutidos pelo autor para fundamentar tais pressupostos. Valsiner aparece como um estudioso contemporâneo e em evidência, cujas premissas reivindicam mudanças, principalmente nas pesquisas em Psicologia do Desenvolvimento, semelhantes àquelas apresentadas por Bruner há 50 anos. Estas discussões tornam-se relevantes nos "espaços da Psicologia", especialmente aqueles relacionados à pesquisa e à Educação.The aim of this article is to analyse how the mind becomes social regarding Bruner's ideas as well as Valsiner's. Bruner, who considers the mind as meanings creator, seeks at understanding the interaction through which the mind constitutes and is constituted by the environment. Bruner proposes a psychology which is interested in the action, its situational feature as well as the way which human beings produce meanings within cultural contexts. According to the author these people are results from the meanings production process, accomplished with the aid of the environmental symbolic systems. This article will approach the themes once discussed by the author so as to serve as a basis to such assumptions. Valsiner will appear as a contemporary scholar in activity, whose premises claim changes, particularly researches in Development Psychology which are similar to those presented by Bruner 50 years ago.

  17. New study reveals twice as many asteroids as previously believed

    Science.gov (United States)

    2002-05-01

    The ISO satellite Credits: ESA ISO An artist's impression of the ISO spacecraft. The ISO Deep Asteroid Search indicates that there are between 1.1 million and 1.9 million 'space rocks' larger than 1 kilometre in diameter in the so-called 'main asteroid belt', about twice as many as previously believed. However, astronomers think it is premature to revise current assessments of the risk of the Earth being hit by an asteroid. Despite being in our own Solar System, asteroids can be more difficult to study than very distant galaxies. With sizes of up to one thousand kilometres in diameter, the brightness of these rocky objects may vary considerably in just a few minutes. They move very quickly with respect to the stars - they have been dubbed 'vermin of the sky' because they often appear as trails on long exposure images. This elusiveness explains why their actual number and size distribution remains uncertain. Most of the almost 40,000 asteroids catalogued so far (1) orbit the Sun forming the 'main asteroid belt', between Mars and Jupiter, too far to pose any threat to Earth. However, space-watchers do keep a closer eye on another category of asteroids, the 'Near Earth Asteroids' or 'NEAs', which are those whose orbits cross, or are likely to cross, that of our planet. The ISO Deep Asteroid Search (IDAS), the first systematic search for these objects performed in infrared light, focused on main belt asteroids. Because it is impossible to simply point the telescope at the whole main belt and count, astronomers choose selected regions of the belt and then use a theoretical model to extrapolate the data to the whole belt. Edward Tedesco (TerraSystems, Inc., New Hampshire, United States) and François-Xavier Desert (Observatoire de Grenoble, France) observed their main belt selected areas in 1996 and 1997 with ESA's ISO. They found that in the middle region of the belt the density of asteroids was 160 asteroids larger than 1 kilometre per square degree - an area of the

    Full Text Available Este artigo apresenta uma introdução à aproximação sociocultural à mente, de James V. Wertsch. Um primeiro pressuposto da aproximação sociocultural é a noção de que a "ação mediada" é a unidade de análise. A partir dessa perspectiva, a ação humana tipicamente emprega ferramentas culturais, ou meios mediacionais, que são fornecidos por um cenário sociocultural particular. O uso concreto dessas ferramentas culturais envolve uma "tensão irredutível" entre agentes ativos e itens como computadores, livros, linguagem, entre outros. O objetivo do presente trabalho é apresentar a aproximação sociocultural de Wertsch como possível referencial teórico para o ensino de ciências e para as pesquisas nessa área.

    Full Text Available OBJECTIVE: As insomnia is highly prevalent, and side effects of medication are well-known, mind-body interventions are increasingly being sought. The objective of this study is to present a narrative review regarding the effects of mind-body interventions for the treatment of insomnia. METHOD: A PubMed search was conducted including only randomized, controlled trials in which the main objective was to treat insomnia. DISCUSSION: Twelve studies were selected. In three of the studies, objective parameters (polysomnography were analyzed. Mind-body interventions were able to improve sleep efficiency and total sleep time. Most can ameliorate sleep quality; some can reduce the use of hypnotic drugs in those who are dependent on these drugs. CONCLUSION: According to the studies we selected, self-reported sleep was improved by all mind-body treatments, among them yoga, relaxation, Tai Chi Chih and music. Cognitive behavioral therapy seems to be the most effective mind-body intervention. Cognitive behavioral therapy was the only intervention that showed better results than medication. However, considering that only five of the twelve studies chosen reached a score of 3 in the Jadad scale, new studies with a higher methodological quality have to be conducted especially in mind-body interventions that belong to the complementary or alternative medicine field.OBJETIVO: Considerando-se que a insônia é altamente prevalente, e os efeitos colaterais das medicações para seu tratamento são bem conhecidos, pesquisas no campo das intervenções mente-corpo têm sido desenvolvidas.

    The purpose of this study was to evaluate the efficacy of CyberKnife for recurrent previously irradiated head and neck cancer. Thirty-one patients with recurrent previously irradiated head and neck cancer were treated with a CyberKnife from July 1999 to March 2002 at Okayama Kyokuto Hospital were retrospectively studied. The accumulated dose was 28-80 Gy (median 60 Gy). The interval between CyberKnife treatment and previous radiotherapy was 0.4-429.5 months (median 16.3 months). Primary lesions were nasopharynx: 7, maxillary sinus: 6, tongue: 5, ethmoid sinus: 3, and others: 1. The pathology was squamous cell carcinoma: 25, adenoid cystic carcinoma: 4, and others: 2. Symptoms were pain: 8, and nasal bleeding: 2. The prescribed dose was 15.0-40.3 Gy (median 32.3 Gy) as for the marginal dose. The response rate (complete response (CR)+partial response (PR)) and local control rate (CR+PR+no change (NC)) was 74% and 94% respectively. Pain disappeared for 4 cases, relief was obtained for 4 cases and no change for 2 cases and nasal bleeding disappeared for 2 cases for an improvement of symptoms. An adverse effects were observed as mucositis in 5 cases and neck swelling in one case. Prognosis of recurrent previously irradiated head and neck cancer was estimated as poor. Our early experience shows that CyberKnife is expected to be feasible treatment for recurrent previously irradiated head and neck cancer, and for the reduction adverse effects and maintenance of useful quality of life (QOL) for patients.

  6. The emotional harbinger effect: Poor context memory for cues that previously predicted something arousing

    Science.gov (United States)

    Mather, Mara; Knight, Marisa

    2009-01-01

    A key function of memory is to use past experience to predict when something important might happen next. Indeed, cues that previously predicted arousing events (emotional harbingers) garner more attention than other cues. However, the current series of five experiments demonstrates that people have poorer memory for the context of emotional harbinger cues than of neutral harbinger cues. Participants first learned that some harbinger cues (neutral tones or faces) predicted emotionally arousing pictures and others predicted neutral pictures. Then they studied associations between the harbinger cues and new contextual details. They were worse at remembering associations with emotional harbingers than with neutral harbingers. Memory was impaired not only for the association between emotional harbingers and nearby digits but also for contextual details that overlapped with or were intrinsic to the emotional harbingers. However, new cues that were inherently emotionally arousing did not yield the same memory impairments as the emotional harbingers. Thus, emotional harbinger cues seem to suffer more from proactive interference than do neutral harbinger cues, impairing formation of new associations with cues that previously predicted something arousing.

  7. Improvements to previous algorithms to predict gene structure and isoform concentrations using Affymetrix Exon arrays

    Full Text Available Abstract Background Exon arrays provide a way to measure the expression of different isoforms of genes in an organism. Most of the procedures to deal with these arrays are focused on gene expression or on exon expression. Although the only biological analytes that can be properly assigned a concentration are transcripts, there are very few algorithms that focus on them. The reason is that previously developed summarization methods do not work well if applied to transcripts. In addition, gene structure prediction, i.e., the correspondence between probes and novel isoforms, is a field which is still unexplored. Results We have modified and adapted a previous algorithm to take advantage of the special characteristics of the Affymetrix exon arrays. The structure and concentration of transcripts -some of them possibly unknown- in microarray experiments were predicted using this algorithm. Simulations showed that the suggested modifications improved both specificity (SP and sensitivity (ST of the predictions. The algorithm was also applied to different real datasets showing its effectiveness and the concordance with PCR validated results. Conclusions The proposed algorithm shows a substantial improvement in the performance over the previous version. This improvement is mainly due to the exploitation of the redundancy of the Affymetrix exon arrays. An R-Package of SPACE with the updated algorithms have been developed and is freely available.

    2017-01-01

    Set to begin data taking at the end of 2018, the Belle II experiment is the next-generation B-factory experiment hosted at KEK in Tsukuba, Japan. The experiment represents the cumulative effort from the collaboration of experimental and detector physics, computing, and software development. Taking everything learned from the previous Belle experiment, which ran from 1998 to 2010, Belle II aims to probe deeper than ever before into the field of heavy quark physics. By achieving an integrated luminosity of 50 ab−1 and accumulating 50 times more data than the previous experiment across its lifetime, along with a rewritten analysis framework, the Belle II experiment will push the high precision frontier of high energy physics. This paper will give an overview of the key components and development activities that make the Belle II experiment possible.

    Full Text Available A CFD code, using a mixed finite volumes - finite elements method on tetraedrons, is now available for engine simulations. The code takes into account the displacement of moving walls such as piston and valves in a full automatic way: a single mesh is used for a full computation and no intervention of the user is necessary. A fourth order implicit spatial scheme and a first order implicit temporal scheme are used. The work presented in this paper is part of a larger program for the validation of this new numerical tool for engine applications. Here, comparisons between computation and experiments of the intake and compression strokes of a four-valve engine were carried out. The experimental investigations are conducted on a single cylinder four valve optical research engine. The turbulence intensity, mean velocity components, tumble and swirl ratios in the combustion chamber are deduced from the LDV measurements. The comparisons between computations and experiments are made on the mean velocity flow field at different locations inside the chamber and for different crank angles. We also present some global comparisons (swirl and tumble ratios. The simulation shows excellent agreement between computations and experiments. Un code de calcul utilisant une approche mixte éléments finis - volumes finis en tétraèdres a été développé pour les simulations moteur.

    Many epoch-making biological discoveries (e.g. Darwinian Theory) were based upon observations. Nevertheless, observation is often regarded as `just looking' rather than a basic scientific skill. As observation is one of the main research methods in biological sciences, it must be considered as an independent research method and systematic practice of this method is necessary. Because observation skills form the basis of further scientific methods (e.g. experiments or comparisons) and children from the age of 4 years are able to independently generate questions and hypotheses, it seems possible to foster observation competency at a preschool level. To be able to provide development-adequate individual fostering of this competency, it is first necessary to assess each child's competency. Therefore, drawing on the recent literature, we developed in this study a competency model that was empirically evaluated within learners ( N = 110) from different age groups, from kindergarten to university. In addition, we collected data on language skills, domain-specific interest and previous knowledge to analyse coherence between these skills and observation competency. The study showed as expected that previous knowledge had a high impact on observation competency, whereas the influence of domain-specific interest was nonexistent. Language skills were shown to have a weak influence. By utilising the empirically validated model consisting of three dimensions (`Describing', `Scientific reasoning' and `Interpreting') and three skill levels, it was possible to assess each child's competency level and to develop and evaluate guided play activities to individually foster a child's observation competency.

    (1) Review and report our experience performing medialization thyroplasty (MT) in previously irradiated patients and (2) compare complications and voice outcomes in 2 cohorts (irradiated vs nonradiated) to evaluate safety and efficacy. Case series with chart review. Academic medical center. All patients (44 total) who underwent MT from 2011 to 2015. Demographic data, complications, and acoustic and subjective voice outcome parameters were collected. The complication rates and voice outcome results were compared between 2 cohorts: patients with a history of radiation to the neck versus those with no radiation history. There were 7 previously irradiated patients and 37 nonradiated patients, with median follow-up of 314 and 538 days, respectively. One complication was noted in each group, and this complication rate was not significantly different (P = .26). Both cohorts demonstrated significant postoperative improvement in subjective voice assessment (P = .04, P < .0001) as well as maximum phonation time (P = .02, .001) when compared with preoperative data. Our study suggests that MT can be safely and effectively performed in irradiated patients. We found no statistically significant difference in the safety of performing MT in irradiated versus nonradiated patients, and there was significant improvement in subjective voice parameters and maximum phonation time in both groups. A larger prospective study is required to statistically determine whether the significant improvements in objective parameters seen in the nonradiated group are present in irradiated patients as well. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    Full Text Available The manufacturing of a functional hollow mechanical element or ring of the AA5083 alloy previously equal channel angular extrusion (ECAE processed, which presents a submicrometric microstructure, is dealt with. For this purpose, the design of two isothermal forging dies (preform and final shape is carried out using the design of experiments (DOE methodology. Moreover, after manufacturing the dies and carrying out tests so as to achieve real rings, the mechanical properties of these rings are analysed as well as their microstructure. Furthermore, a comparison between the different forged rings is made from ECAE-processed material subjected to different heat treatments, previous to the forging stage. On the other hand, the ring forging process is modelled through the use of finite element simulation in order to improve the die design and to study the force required for the isothermal forging, the damage value, and the strain the material predeformed by ECAE has undergone. With this present research work, it is intended to improve the knowledge about the mechanical properties of nanostructured material and the applicability of this material to industrial processes that allow the manufacturing of functional parts.

    To describe the association between participants' person-related potential predictor variables and cumulative compliance with interventions for preventing ankle sprains: neuromuscular training, wearing an ankle brace, and a combined training and bracing. Secondary analysis of compliance data from a randomized controlled trial (RCT) comparing measures preventing ankle ligament injuries. Ordinal regression with a backward selection method was used to obtain a descriptive statistical model linking participants' person-related potential predictor variables with the monthly cumulative compliance measurements for three interventions preventing ankle ligament injuries. Having had a previous ankle injury was significantly associated with a higher compliance with all of the preventive measures trialed. Overall compliance with bracing and the combined intervention was significantly lower than the compliance with NM training. Per group analysis found that participating in a high-risk sport, like soccer, basketball, and volleyball, was significantly associated with a higher compliance with bracing, or a combined bracing and NM training. In contrast, participating in a high-risk sport was significantly associated with a lower per group compliance with NM training. Future studies should include at least registration of previous ankle sprains, sport participation (high- or low-risk), experience in NM training, and hours of sport exposure as possible predictors of compliance with interventions preventing ankle sprains. Practitioners should take into account these variables when prescribing preventive neuromuscular training or bracing. Copyright © 2015 Sports Medicine Australia. Published by Elsevier Ltd.

    The acute toxicity of organophosphates (OPs) has been studied extensively; however, much less attention has been given to the subject of repeated exposures that are not associated with overt signs of toxicity (i.e., subthreshold exposures). The objective of this study was to determine if the protracted spatial learning impairments we have observed previously after repeated subthreshold exposures to the insecticide chlorpyrifos (CPF) or the alkylphosphate OP, diisopropylfluorophosphate (DFP) persisted for longer periods after exposure. Male Wistar rats (beginning at two months of age) were initially injected subcutaneously with CPF (10.0 or 18.0mg/kg) or DFP (0.25 or 0.75 mg/kg) every other day for 30 days. After an extended OP-free washout period (behavioral testing begun 50 days after the last OP exposure), rats previously exposed to CPF, but not DFP, were impaired in a radial arm maze (RAM) win-shift task as well as a delayed non-match to position procedure. Later experiments (i.e., beginning 140 days after the last OP exposure) revealed impairments in the acquisition of a water maze hidden platform task associated with both OPs. However, only rats previously exposed to DFP were impaired in a second phase of testing when the platform location was changed (indicative of deficits of cognitive flexibility). These results indicate, therefore, that repeated, subthreshold exposures to CPF and DFP may lead to chronic deficits in spatial learning and memory (i.e., long after cholinesterase inhibition has abated) and that insecticide and alkylphosphate-based OPs may have differential effects depending on the cognitive domain evaluated.

    External beam radiation to the neck is widely considered a contraindication for thyroplasty due to concern for infection and implant extrusion. We present a case series of our experience regarding thyroplasty performed in a previously radiated field. Retrospective case study at a tertiary academic referral center. Using the institution's clinical notes search tool, records from 1999 through 2014 documenting thyroplasty and radiation were identified and reviewed. Patients who received external beam radiation to the operative field prior to thyroplasty were included. Data including duration of radiation, timing and specifics of thyroplasty, postoperative complications, risk factors, clinical voice outcomes, and length of follow-up were collected. Fourteen patients met criteria for the study. Of all thyroplasty performed, 11 were Silastic implants, two were Gore-Tex implants, six had concurrent arytenoid adduction, and one was a midline type II thyroplasty. In terms of risk factors for postoperative complications, two were diabetic, none were active smokers, and one had a splenectomy. All patients were given postoperative antibiotics. The median duration of follow-up after surgery was 14.2 months. No patients were found to have postoperative complications. Pre- and postoperative voice data were assessed. Overall, there was improvement in voice outcomes. Thyroplasty may be an option for patients who have previously undergone external beam radiation. Short-term and intermediate outcomes in our patients showed no postoperative complications, and generally voice or dysphagia improved. Careful selection is still warranted when considering thyroplasty in a previously irradiated neck, and long-term outcomes need further study. 4 Laryngoscope, 126:1849-1853, 2016. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    Full Text Available Purpose. To examine the association between previous preterm birth and the risk of stillbirth. Methods. This population-based retrospective cohort study analyzed live births and stillbirth records in Missouri (1989–1997. The main outcome of interest was stillbirth occurrence while the exposures were prior preterm birth. Adjusted odds ratios and 95% confidence intervals were computed using logistic regression. Results. Women who had a previous preterm birth have 63% increased odds of stillbirth in singleton pregnancies and 75% increased odds in twins as compared to those who did not have a preterm birth in a prior pregnancy (AOR = 1.63, 95% CI = 1.41–1.88 and AOR = 1.75, 95% CI = 1.20–2.56, respectively. The most significant risk factor for stillbirth in singleton pregnancies was uterine bleeding (AOR = 5.89, 95% CI = 5.13–6.76. In twin pregnancies, it was the condition hydramnios/oligohydramnios (AOR = 4.72, 95% CI = 3.70–6.02. Eclampsia was associated with a heightened risk of stillbirth in singletons (AOR = 2.45, 95% CI = 1.41–4.12, but not in twins (AOR = 0.96, 95% CI = 0.13–7.00. Black mothers were more likely than white to experience stillbirth (AOR = 2.10, 95% CI = 1.99–2.22 for singletons and AOR = 1.51, 95% CI = 1.27–1.79 for twins. Conclusion. Stillbirth is a vital public health issue and its etiology is not well understood. Previous history of preterm birth was found to be associated with future stillbirth. Targeted early medical and obstetric care and interventions among women with preterm birth history may potentially reduce the likelihood of stillbirth.

    Full Text Available Scopo del presente lavoro è indagare il processo esperito da lettori di testi narrativi letterari in prosa. Ci si muoverà nell’ambito della narratologia cognitiva e, attingendo a recenti ricerche neuroscientifiche, ci si soffermerà in particolare su due nozioni: la nozione di ‘simulazione incarnata’, così come definita dal neurofisiologo Vittorio Gallese, membro dell’équipe che ha individuato i neuroni specchio, e la nozione di ‘teoria della mente’, elaborata in ambito filosofico e psicologico, di cui ha già cominciato a essere sondato il potenziale applicativo in campo letterario – seppur con alcuni limiti – da diversi narratologi, fra cui Lisa Zunshine e Alan Palmer. Verranno illustrati i capisaldi teorici di queste due nozioni, se ne mostreranno le divergenze e, infine, ne verrà testata l’efficacia attraverso l’analisi di alcuni brani tratti dal romanzo di Virginia Woolf Mrs. Dalloway. Emergerà come il meccanismo di simulazione incarnata alla base dell’‘embodied narratology’ si riveli uno strumento euristico fondamentale e necessario per integrare e completare la teoria della mente che, per quanto utile, non si dimostra in grado di spiegare la complessità dell’esperienza della lettura perché non rende conto del coinvolgimento corporeo che gli studi neuroscientifici hanno mostrato essere una componente di primaria importanza del nostro modo di interagire con gli altri nella realtà e, similmente, con le menti dei personaggi in un contesto finzionale.

    Our aim was to demonstrate the effect of insicion of renal parenchyma during open renal stone surgery (ORSS) on percutaneous nephrolithotomy (PNL) outcomes. Patients with history of ORSS who underwent PNL operation between June 2005 and June 2015 were analyzed retrospectively. Patients were divided into two groups according to their type of previous ORSS. Patients who had a history of ORSS with parenchymal insicion, such as radial nephrotomies, anatrophic nephrolithotomy, lower pole resection, and partial nephrectomy, were included in Group 1. Other patients with a history of open pyelolithotomy were enrolled in Group 2. Preoperative characteristics, perioperative data, stone-free status, and complications were compared between the groups. Stone-free status was defined as complete clearance of stone(s) or presence of residual fragments smaller than 4 mm. The retrospective nature of our study, different experience level of surgeons, and lack of the evaluation of anesthetic agents and cost of procedures were limitations of our study. 123 and 111 patients were enrolled in Groups 1 and 2, respectively. Preoperative characteristics were similar between groups. In Group 1, the mean operative time was statistically longer than in Group 2 (p=0.013). Stone-free status was significantly higher in Group 2 than in Group 1 (p=0.027). Complication rates were similar between groups. Hemorrhage requiring blood transfusion was the most common complication in both groups (10.5% vs. 9.9%). Our study demonstrated that a history of previous ORSS with parenchymal insicion significantly reduces the success rates of PNL procedure.

    To describe our clinical experience in wavefront-guided LASIK enhancements using the WaveLight ALLEGRETTO system (WaveLight Technologie AG, Erlangen, Germany) for symptomatic eyes previously treated with standard LASIK. Twenty-six eyes of 20 patients with residual myopia, hyperopia, or mixed astigmatism and/or night vision symptoms after primary standard LASIK were considered for wavefront-guided customized retreatment using the WaveLight ALLEGRETTO WAVE 200 Hz excimer laser system (model 106). Preoperative best spectacle-corrected visual acuity (BSCVA), uncorrected visual acuity, topography with the ALLEGRETTO Topolyzer, wavefront analysis using the ALLEGRETTO WAVE Tscherning Analyzer, and contrast sensitivity were compared to postoperative (enhancement) measurements. Twenty-two of the original 26 eyes underwent wavefront-guided enhancement, 4 were excluded because they did not meet wavefront-guided treatment inclusion guidelines of this study. Mean follow-up was 8 months (range: 6 to 13 months, standard deviation [SD] 2). All patients were within +/- 0.50 diopters (manifest refraction) of intended postoperative refraction. The mean preoperative BSCVA improved from 20/25 (SD +/- 0.12) to 20/18 (SD +/- 0.1) postoperatively. All patients gained at least one line of BSCVA, and a maximum of three lines. There was no loss of BSCVA in any patient. The total amount of high order aberrations (RMSH) decreased from an average of 1.04 (SD +/- 0.22) to 0.46 (SD +/- 0.14) microm. Patients also had a mean improvement in low contrast sensitivity of 59%. Based on this small series, customized wavefront-guided enhancements using the WaveLight ALLEGRETTO system in patients who underwent previous LASIK appear to be safe and effective in correcting residual refractive error, reducing high order aberrations, and improving visual symptoms when reliable and reproducible measurements are achieved.

    The EU currently lacks reliable data on the prevalence and incidence of mental disorders in older people. Despite the availability of several national and international epidemiological studies, the size and burden of mental disorders in the elderly remain unclear due to various reasons. Therefore, the aims of the MentDis_ICF65+ study are (1) to adapt existing assessment instruments, and (2) to collect data on the prevalence, the incidence, and the natural course and prognosis of mental disorders in the elderly. Using a cross-sectional and prospective longitudinal design, this multi-centre study from six European countries and associated states (Germany, Great Britain, Israel, Italy, Spain, and Switzerland) is based on age-stratified, random samples of elderly people living in the community. The study program consists of three phases: (1) a methodological phase devoted primarily to the adaptation of age- and gender-specific assessment tools for older people (e.g., the Composite International Diagnostic Interview, CIDI) as well as psychometric evaluations including translation, back translation; (2) a baseline community study in all participating countries to assess the lifetime, 12 month and 1 month prevalence and comorbidity of mental disorders, including prior course, quality of life, health care utilization and helpseeking, impairments and participation and, (3) a 12 month follow-up of all baseline participants to monitor course and outcome as well as examine predictors. The study is an essential step forward towards the further development and improvement of harmonised instruments for the assessment of mental disorders as well as the evaluation of activity impairment and participation in older adults. This study will also facilitate the comparison of cross-cultural results. These results will have bearing on mental health care in the EU and will offer a starting point for necessary structural changes to be initiated for mental health care policy at the level of

    Full Text Available The development of inexperienced researchers is crucial. In response to the lack of research self-efficacy of many previously disadvantaged individuals, the article examines how mentoring can enhance the research self-efficacy of mentees. The study is grounded in the self-efficacy theory (SET – an aspect of the social cognitive theory (SCT. Insights were gained from an in-depth study of SCT, SET and mentoring, and from a completed mentoring project. This led to the formulation of three basic principles. Firstly, institutions need to provide supportive environmental conditions that facilitate research selfefficacy. This implies a supportive and efficient collective system. The possible effects of performance ratings and reward systems at the institution also need to be considered. Secondly, mentoring needs to create opportunities for young researchers to experience successful learning as a result of appropriate action. To this end, mentees need to be involved in actual research projects in small groups. At the same time the mentor needs to facilitate skills development by coaching and encouragement. Thirdly, mentors need to encourage mentees to believe in their ability to successfully complete research projects. This implies encouraging positive emotional states, stimulating self-reflection and self-comparison with others in the group, giving positive evaluative feedback and being an intentional role model.

    Franklin, Allan

    2008-01-01

    In Experiment, Right or Wrong, Allan Franklin continues his investigation of the history and philosophy of experiment presented in his previous book, The Neglect of Experiment. In this new study, Franklin considers the fallibility and corrigibility of experimental results and presents detailed histories of two such episodes: 1) the experiment and the development of the theory of weak interactions from Fermi's theory in 1934 to the V-A theory of 1957 and 2) atomic parity violation experiments and the Weinberg-Salam unified theory of electroweak interactions of the 1970s and 1980s. In these episodes Franklin demonstrates not only that experimental results can be wrong, but also that theoretical calculations and the comparison between experiment and theory can also be incorrect. In the second episode, Franklin contrasts his view of an "evidence model" of science in which questions of theory choice, confirmation, and refutation are decided on the basis of reliable experimental evidence, with that proposed by the ...

    Full Text Available Introduction. L’autorité européenne de sécurité des aliments (AESA assure que les laits de croissance « n’apportent pas de valeur supplémentaire à une alimentation équilibrée pour répondre aux besoins nutritionnels des enfants en bas âge ». Objectifs. Cette étude quantifie les modifications alimentaires minimales nécessaires pour atteindre l’adéquation nutritionnelle chez des enfants en bas âge selon leur consommation ou non de laits de croissance et/ou de compléments. Méthodologie. L’application de modèles de programmation linéaire aux données de l’enquête alimentaire nationale au Royaume Uni sur les consommations alimentaires de 1147 enfants de 12-18 mois a permis d’identifier les modifications alimentaires minimales nécessaires, d’abord en changeant uniquement les quantités des aliments déjà consommés par chaque enfant (répertoire alimentaire, puis en autorisant l’introduction de nouveaux aliments. Résultats. Le groupe d’enfants ne consommant ni laits de croissance ni compléments était majoritaire (61,6 %. Pour seulement 1% de ces enfants, il était possible d’atteindre l’adéquation nutritionnelle à partir des aliments de leur répertoire alimentaire, contre 74,4% des enfants du groupe consommant des laits de croissance et des compléments. Lorsque l’introduction de nouveaux aliments était autorisée, les changements alimentaires requis étaient moindres lorsque les laits de croissance et les compléments faisaient initialement partie du répertoire de l’enfant. Dans l’échantillon total, les principales modifications alimentaires requises étaient une augmentation du lait de croissance et une diminution du lait de vache (respectivement +226 et −181 g/jour. Conclusions. Augmenter la consommation de lait de croissance et/ou des compléments constitue la voie la plus simple de couverture des recommandations nutritionnelles de l’AESA.

    A system that applies attribute and topology based change detection to networks of objects that were detected on previous scans of a structure, roadway, or area of interest. The attributes capture properties or characteristics of the previously detected objects, such as location, time of detection, size, elongation, orientation, etc. The topology of the network of previously detected objects is maintained in a constellation database that stores attributes of previously detected objects and implicitly captures the geometrical structure of the network. A change detection system detects change by comparing the attributes and topology of new objects detected on the latest scan to the constellation database of previously detected objects.

    Potential bone marrow donors are screened to ensure the safety of both the donor and recipient. At our institution, potential donors with abnormal peripheral blood cell counts, a personal history of malignancy, or age >60 years are evaluated to ensure that they are viable candidates for donation. Evaluation of the marrow includes morphologic, flow cytometric, and cytogenetic studies. A total of 122 potential donors were screened between the years of 2001 and 2011, encompassing approximately 10% of all donors. Of the screened potential donors, the mean age was 59 years and there were 59 men and 63 women. The donors were screened because of age >60 years (n = 33), anemia (n = 22), cytopenias other than anemia (n = 27), elevated peripheral blood counts without a concurrent cytopenia (n = 20), elevated peripheral blood counts with a concurrent cytopenia (n = 10), history of malignancy (n = 4), abnormal peripheral blood differential (n = 3), prior graft failure (n = 1), history of treatment with chemotherapy (n = 1), and body habitus (n = 1). Marrow abnormalities were detected in 9% (11 of 122) of donors. These donors were screened because of anemia (5 of 22, 23%), age >60 years (2 of 33, 6%), history of malignancy (2 of 4, 50%), elevated peripheral blood counts (1 of 20, 5%), and body habitus (1 of 1, 100%). Abnormalities included plasma cell dyscrasia (n = 3), abnormal marrow cellularity (n = 3), clonal cytogenetic abnormalities (n = 2), low-grade myelodysplastic syndrome (1), a mutated JAK2 V617F allele (n = 1), and monoclonal B cell lymphocytosis (n = 1). Our experience indicates that extended screening of potential donors identifies a significant number of donors with previously undiagnosed marrow abnormalities.

    Postpartum depression (PPD) is a common disorder after childbirth. The strongest known predictors are a history of depression and/or a history of PPD. However, for a significant proportion of women, PPD constitutes their first depressive episode. This study aimed to gain further insight into the risk factors for PPD in first time mothers without previous psychiatric contact. Women delivering in Uppsala University Hospital, Sweden, from May 2006 to June 2007, were asked to participate and filled out questionnaires five days and six weeks postpartum, containing inter alia the Edinburgh Postnatal Depression Scale (EPDS). Univariate logistic regression models, as well as a path analysis, were performed to unveil the complex interplay between the study variables. Of the 653 participating primiparas, 10.3% and 6.4% reported depressive symptoms (EPDS≥12 points) five days and six weeks postpartum, respectively. In the path analysis, a positive association between anxiety proneness and depressive symptoms at five days and six weeks postpartum was identified. For depressive symptoms six weeks after delivery, additional risk factors were detected, namely depressive symptoms five days postpartum and subjective experience of problems with the baby. Caesarean section and assisted vaginal delivery were associated with fewer depressive symptoms at 6 six weeks postpartum. Identification of anxiety proneness, delivery mode and problems with the baby as risk factors for self-reported depressive symptoms postpartum in this group of primiparas can be important in helping health care professionals identify women at increased risk of affective disorders in the perinatal period, and provide a base for early intervention.

    Stereotactically guided external beam irradiation may be a useful form of treatment for small, well-circumscribed, but surgically inaccessible, primary brain tumors that are either benign or of low malignant potential. Between March 1988 and December 1991, 10 children and adolescents with previously untreated primary brain tumors were treated with stereotactic external beam irradiation (SEBI) using a linac-based dynamic technique. Eleven lesions were treated in the 10 patients. Treatment was given using a collimator diameter of 1.5-4 cm (median 2 cm). Single fractions of 18, 20, and 25 Gy were used for 3 lesions in 2 patients. A fractionated schedule delivering a median dose of 42 Gy in 6 fractions over 2 weeks was used in the remaining 8 patients. Morbidity related to treatment was minimal. Three patients suffered a temporary worsening of preexisting neurological symptoms and/or signs at 2, 5, and 5 months posttreatment, with subsequent recovery in all. With a median follow up post-SEBI of 17.5 months (range 5-47 months), improvement in neurological findings related to the lesion was noted for 5 treated lesions; 6 remained clinically stable. Seven of the 11 treated lesions improved radiologically, and only 2 showed evidence of progressive disease. Stereotactic external beam irradiation represents a potentially valuable therapeutic option for selected primary brain tumors in the pediatric and adolescent age group. Morbidity related to the treatment appears acceptable in frequency and type, and preliminary data with regard to response are encouraging. However, in order to assess the impact of such treatment on long-term tumor control and survival, further experience with a larger cohort of patients followed for a longer period of time will be necessary.

    The numerical simulation of industrial devices where heat transfer is obtained by electrical conduction, generally leads to the simultaneous resolution of electrical and thermal equations coupled by electrical properties often strongly linked with temperature. After describing physical phenomena equations, a finite element discretization of partial derivative equations is presented. Fifteen different formulations have been generated with the FLUX-EXPERT package allowing the modelization of many industrial systems in 2D, axisymetric or 3D geometries with or without equations coupling. Modelized problems are generally non linear and complicated. Matrices systems are dissymetric and ill-condionned. In order to optimize the resolution a Newton Raphson algorithm is used. Two applications are treated: i) a glass furnace with balanced and unbalanced AC supply; ii) a traveling fluid heated by electrical conduction with DC supply. La simulation numérique de dispositifs industriels de chauffage par conduction électrique conduit à la résolution simultanée des équations électrique et thermique couplées par les propriétés électriques souvent fortement dépendantes de la température. Après une mise en équation des phénomènes physiques, la discrétisation en éléments finis des équations aux dérivées partielles est présentée. Quinze formulations différentes ont été générées à l'aide du logiciel FLUX-EXPERT, permettant ainsi de modéliser de nombreuse configurations industrielles (2D, axisymétriques et 3D) avec ou sans couplage fort entre les équations. Les problèmes modélisés sont généralement non linéaires et complexes. Ils conduisent à des systèmes mal conditionnés dissymétriques. Afin d'en optimiser la résolution un algorithme de Newton Raphson est utilisé. Deux installations industrielles ont été étudiées: i) un four à verre alimenté en tension polyphasée équilibrée et déséquilibrée; ii) un dispositif de chauffage de

    Full Text Available Previous research has shown that participants' strategy choices can be influenced by the previously-used strategy. This'perseveration effect' has been demonstrated both after a repeated use of the previous strategy (e.g., Schillemans, Luwel, Bulté, Onghena, & Verschaffel, 2009, but also after a single use of the previous strategy (Lemaire & Lecacheur, 2010. In the present study, we tested whether this perseveration effect would be stronger after a repeated than after a single previous strategy application. We were able to replicate the perseveration effect but we did not find evidence for an influence of the number of previous strategy applications on the strength of this effect. An additional cluster analysis revealed that only about one third of the participants was susceptible for the perseveration effect. The theoretical, methodological, and educational implications of these results are discussed.

    To re-evaluate in a larger cohort of patients if the maternal serum biochemical markers used in first trimester aneuploidy screening have the same marker distributions in pregnancies with a previous history of aneuploidy compared with those that have no previous history. Information related to previous pregnancy history is routinely recorded as part of first trimester screening in three centres King George, Kings College and Fetal Medicine Centre, London. From the database, records were extracted for women who had a previous pregnancy diagnosed with trisomies 13, 18 or 21. For each woman with a previous aneuploidy, five unaffected pregnancies in women of the same maternal age and with no previous aneuploidy pregnancy were selected as controls. A comparison was made between the marker distributions for pregnancy associated plasma protein-A (PAPP-A) and free beta-human chronic gonadotrophin (beta-hCG) amongst the cases and controls using nonparametric statistical tests. A series of 8240 controls were compared against group of 1032 cases with a previous trisomy 21, 293 with a previous trisomy 18 and 158 with a previous trisomy 13. Cases with multiple previous trisomies were excluded. There were no significant differences in the level of free beta-hCG; however, in cases of trisomy 21 and trisomy 13 the levels of PAPP-A were increased by 5 and 16%, respectively. Risk calculation algorithms may need to take account of the increased PAPP-A levels in women with a previous trisomy 21 or trisomy 13. Copyright (c) 2009 John Wiley & Sons, Ltd.

    For patients suffering of recurrent breast cancer within the irradiated breast, generally mastectomy is recommended. The normal tissue tolerance does not permit a second full-dose course of radiotherapy to the entire breast after a second breast-conserving surgery (BCS). A novel option is to treat these patients with partial breast irradiation (PBI). This approach is based on the hypothesis that re-irradiation of a limited volume will be effective and result in an acceptable frequency of side effects. The following report presents a single center experience with intraoperative radiotherapy (IORT) during excision of recurrent breast cancer in the previously irradiated breast. Between 4/02 and 11/06, 15 patients were treated for in-breast recurrences at a median of 10 years (3–25) after previous EBRT (10 recurrences in the initial tumor bed, 3 elsewhere in-breast failures, 2 invasive recurrences after previous DCIS). Additional 2 patients were selected for IORT with new primary breast cancer after previous partial breast EBRT for treatment of Hodgkin's disease. IORT with a single dose of 14.7 – 20 Gy 50 kV X-rays at the applicator surface was delivered with the Intrabeam™-device (Carl Zeiss, Oberkochen, Germany). After a median follow-up of 26 months (1–60), no local recurrence occurred. 14 out of 17 patients are alive and free of disease progression. Two patients are alive with distant metastases. One patient died 26 months after BCS/IORT due to pulmonary metastases diagnosed 19 months after BCS/IORT. Acute toxicity after IORT was mild with no Grade 3/4 toxicities and cosmetic outcome showed excellent/good/fair results in 7/7/3 cases. IORT for recurrent breast cancer using low energy X-rays is a valuable option for patients with recurrent breast cancer after previous radiotherapy

    The impact of previous abdominal surgeries on the need for conversion to open surgery and on short-term outcomes during/after laparoscopic colectomy was retrospectively investigated. This retrospective cohort study was conducted from December 1996 through December 2009. This study was conducted at Osaka Medical College Hospital. A total of 1701 consecutive patients who had undergone laparoscopic resection of the colon and rectum were classified as not having previous abdominal surgery (n = 1121) or as having previous abdominal surgery (n = 580). Short-term outcomes were recorded, and risk factors for conversion to open surgery were analyzed. There were no significant differences in operative time, blood loss, number of lymph nodes removed, or conversion rate between the groups. The rate of inadvertent enterotomy was significantly higher in the previous abdominal surgery group than in the not having previous abdominal surgery group (0.9% versus 0.1%; p = 0.03), and the postoperative recovery time was significantly longer in the previous abdominal surgery group than in the not having previous abdominal surgery group. Ileus was more frequent in the previous abdominal surgery group than in the not having previous abdominal surgery group (3.8% versus 2.1%; p = 0.04). Significant risk factors for conversion to open surgery were T stage ≥3 (OR, 2.81; 95% CI, 1.89-3.75), median incision (OR, 4.34; 95% CI, 1.23-9.41), upper median incision (OR, 2.78; 95% CI, 1.29-5.42), lower median incision (OR, 1.82; 95% CI, 1.09-3.12), and transverse colectomy (OR, 1.76; 95% CI, 1.29-2.41). The incidence of successfully completed laparoscopic colectomy after previous abdominal surgery remains high, and the short-term outcomes are acceptable.

    SUMMARY Setting Previously treated tuberculosis (TB) patients are a priority for drug susceptibility testing (DST) to identify cases with multidrug resistance (MDR). In Cambodia, a recent study found that only one-third of smear-positive previously treated patients had DST results. Objective To quantify the gaps in detecting MDR in previously treated TB patients in Cambodia, and describe health workers’ perspectives on barriers, facilitators and potential interventions. Design We analyzed case notifications in Cambodia (2004–2012) and conducted semi-structured interviews with key stakeholders Results The proportion of previously treated notifications varied significantly across provinces 2010–12, in the context of longer term trends of decreasing relapse and increasing “other” retreatment notifications. Correct classification of patients’ TB treatment history and ensuring specimens from previously-treated patients are collected and reach the laboratory could nearly double the number of detected MDR-TB cases. Identified barriers include patients’ reluctance to disclose and staff difficulty eliciting treatment history, partly due to availability of streptomycin only in hospitals. Facilitators include trained health workers, collection of sputum for DST even if previously treated patients are not taking streptomycin, streamlining sputum transportation and promptly reporting results. Conclusion Improved monitoring, supportive supervision, and correctly classifying previously treated patients are essential for improving detection of MDR-TB. PMID:25299861

    To evaluate the efficacy and safety of external cephalic version (ECV) among women with previous cesarean delivery. A retrospective study was conducted using data for women with previous cesarean delivery and breech presentation who underwent ECV at or after 36 weeks of pregnancy during 2011-2016. For every case, two multiparous women without previous cesarean delivery who underwent ECV and were matched for age and pregnancy duration were included. Characteristics and outcomes were compared between groups. ECV was successful for 32 (84.2%) of 38 women with previous cesarean delivery and 62 (81.6%) in the control group (P=0.728). Multivariate regression analysis confirmed that previous cesarean was not associated with ECV success (odds ratio 1.89, 95% confidence interval 0.19-18.47; P=0.244). Successful vaginal delivery after successful ECV was reported for 19 (59.4%) women in the previous cesarean delivery group and 52 (83.9%) in the control group (Pcesarean delivery. To avoid a repeat cesarean delivery, ECV can be offered to women with breech presentation and previous cesarean delivery who are otherwise eligible for a trial of labor. © 2017 International Federation of Gynecology and Obstetrics.

    Blood services in sub-Saharan Africa experience blood shortages and low retention of voluntary, non-remunerated donors. To boost collections by encouraging repeat donations, the Kenya National Blood Transfusion Service is exploring the likelihood of reaching previous donors through targeted print, radio and television advertising. We analysed data from a national AIDS Indicator Survey to determine whether previous donors have significant exposure to media. Respondents reporting history of blood donation had significantly higher exposure to print, radio and television media than those without history of blood donation. Targeted media campaigns encouraging repeat donation are likely to reach previous donors even in resource-limited settings.

Los procesos orientados a futuro y la previsión episódica (PE, han sido señalados como componentes importantes para ciertos logros evolutivos como la planificación, la auto-regulación y adaptación social. También se ha postulado que pensamiento futuro episódico y teoría de la mente están relacionados, en virtud de su sustrato neural compartido. El primer estudio tuvo por objetivo analizar la coherencia de desarrollo entre las medidas de PE, y de estas con la postergación de la gratificación auto-impuesta controlando según la aptitud general de razonamiento, y participaron 15 niños de 3 y 4 años. El segundo, tuvo por objetivo explorar la relación entre PE, los procesos orientados a futuro, la teoría de la mente controlando según lenguaje, participando 78 niños de 4 años. Los resultados muestran que las diferentes medidas para evaluar la PE son equivalentes. También se encontró un alto grado de coherencia comportamental entre las medidas evaluadas. Sin embargo, los datos no aportan evidencia evolutiva que permitan incluir a la PE dentro de los constructos más amplios estudiados.

    The purpose of this study was to examine the association between previous cesarean delivery and subsequent placenta previa while distinguishing cesarean delivery before the onset of labor from intrapartum cesarean delivery. We conducted a retrospective cohort study of electronic medical records from 20 Utah hospitals (2002-2010) with restriction to the first 2 singleton deliveries of nulliparous women at study entry (n=26,987). First pregnancy delivery mode was classified as (1) vaginal (reference), (2) cesarean delivery before labor onset (prelabor), or (3) cesarean delivery after labor onset (intrapartum). Risk of second delivery previa was estimated by previous delivery mode with the use of logistic regression and was adjusted for maternal age, insurance, smoking, comorbidities, previous pregnancy loss, and history of previa. Most first deliveries were vaginal (82%; n=22,142), followed by intrapartum cesarean delivery (14.6%; n=3931), or prelabor cesarean delivery (3.4%; n=914). Incidence of second delivery previa was 0.29% (n=78) and differed by previous delivery mode: vaginal, 0.24%; prelabor cesarean delivery, 0.98%; intrapartum cesarean delivery, 0.38% (Pdelivery, previous prelabor cesarean delivery was associated with an increased risk of second delivery previa (adjusted odds ratio, 2.62; 95% confidence interval, 1.24-5.56). There was no significant association between previous intrapartum cesarean delivery and previa (adjusted odds ratio, 1.22; 95% confidence interval, 0.68-2.19). Previous prelabor cesarean delivery was associated with a >2-fold significantly increased risk of previa in the second delivery, although the approximately 20% increased risk of previa that was associated with previous intrapartum cesarean delivery was not significant. Although rare, the increased risk of placenta previa after previous prelabor cesarean delivery may be important when considering nonmedically indicated prelabor cesarean delivery.

Tal comprometimento poderia explicar o aparecimento de sintomas psicóticos nestes indivíduos. OBJETIVO: Revisar criticamente a literatura sobre alterações ToM em indivíduos esquizotípicos ou portadores de sintomas psicóticos subsindrômicos. MÉTODOS: Realizou-se uma busca na base MedLine por trabalhos publicados em inglês e português, entre 1990 e 2008, utilizando a frase "Schizotypal Personality Disorder [MeSH] AND "Theory of Mind" OR "Mentalising". RESULTADOS: Foram selecionados 15 artigos, os quais utilizaram diversos desenhos experimentais e instrumentos para avaliação de traços esquizotípicos, propensão à psicose e habilidades ToM. CONCLUSÕES: Os trabalhos revisados visaram estabelecer relações entre vulnerabilidade à psicose e alterações ToM. Alguns artigos também abordaram o caráter traço ou estado dependente das alterações ToM. A maioria dos trabalhos selecionados sugeriu que indivíduos com escores altos para esquizotipia e familiares de esquizofrênicos apresentam problemas no processamento ToM (este teria, portanto, um caráter traço-dependente.

    An asymptomatic 49-year-old woman was admitted for the purpose of surgery for aortic pseudoaneurysm. She had Marfan syndrome and had undergone an emergent Bentall procedure 10 years previously. About six months previously, she could palpate distended bilateral external jugular veins, which became distended only in a supine position and without any other symptoms. Enhanced computed tomography revealed an aortic pseudoaneurysm originating from a previous distal anastomosis site. During induction of general anesthesia in a supine position, bilateral external jugular venous distention was remarkable. Immediately after a successful operation, distention completely resolved. The present case emphasizes the importance of physical examination leading to a diagnosis of asymptomatic life-threatening diseases in patients with a history of previous aortic surgery.

We find that the rates have changed significantly for almost all reactions conside...

  1. Thermal release of D2 from new Be-D co-deposits on previously baked co-deposits

    International Nuclear Information System (INIS)

    Baldwin, M.J.; Doerner, R.P.

    2015-01-01

    Past experiments and modeling with the TMAP code in [1, 2] indicated that Be-D co-deposited layers are less (time-wise) efficiently desorbed of retained D in a fixed low-temperature bake, as the layer grows in thickness. In ITER, beryllium rich co-deposited layers will grow in thickness over the life of the machine. Although, compared with the analyses in [1, 2], ITER presents a slightly different bake efficiency problem because of instances of prior tritium recover/control baking. More relevant to ITER, is the thermal release from a new and saturated co-deposit layer in contact with a thickness of previously-baked, less-saturated, co-deposit. Experiments that examine the desorption of saturated co-deposited over-layers in contact with previously baked under-layers are reported and comparison is made to layers of the same combined thickness. Deposition temperatures of ∼323 K and ∼373 K are explored. It is found that an instance of prior bake leads to a subtle effect on the under-layer. The effect causes the thermal desorption of the new saturated over-layer to deviate from the prediction of the validated TMAP model in [2]. Instead of the D thermal release reflecting the combined thickness and levels of D saturation in the over and under layer, experiment differs in that, i) the desorption is a fractional superposition of desorption from the saturated over-layer, with ii) that of the combined over and under -layer thickness. The result is not easily modeled by TMAP without the incorporation of a thin BeO inter-layer which is confirmed experimentally on baked Be-D co-deposits using X-ray micro-analysis.

    To determine the association between single previous abortion and pregnancy outcome in nulliparous women. A retrospective cohort study of all nulliparous women who delivered in a university-affiliated tertiary hospital (2009-2014). Pregnancy outcome of women with single previous first trimester abortion (study group) was compared to those of primigravida (control group). Of the 44 371 deliveries during the study period, 14 498 (32.6%) were of nulliparous women, of them 1501 (10.3%) had single previous abortion (abortion was independently associated with induction of labor (OR = 1.31, 95%C.I 1.04-1.63, p = 0.01), cesarean section (OR = 1.38, 95%C.I 1.18-1.60, p abortion no difference in pregnancy outcome was observed between those with previous induced termination of pregnancy and spontaneous abortion, except for increased risk for retained placenta in those with previous spontaneous abortion. Single early previous abortion in nulliparous women was associated with higher rate of induction of labor, cesarean section and retained placenta compared to primigravida women.

    In 1977, in a record-time of 9 months, the magnets of the g-2 experiment were modified and used to build a proton/antiproton storage ring: the "Initial Cooling Experiment" (ICE). It served for the verification of the cooling methods to be used for the "Antiproton Project". Stochastic cooling was proven the same year, electron cooling followed later. Also, with ICE the experimental lower limit for the antiproton lifetime was raised by 9 orders of magnitude: from 2 microseconds to 32 hours. For its previous life as g-2 storage ring, see 7405430.

  13. Dissociation in decision bias mechanism between probabilistic information and previous decision

    Full Text Available Target detection performance is known to be influenced by events in the previous trials. It has not been clear, however, whether this bias effect is due to the previous sensory stimulus, motor response, or decision. Also it remains open whether or not the previous trial effect emerges via the same mechanism as the effect of knowledge about the target probability. In the present study, we asked normal human subjects to make a decision about the presence or absence of a visual target. We presented a pre-cue indicating the target probability before the stimulus, and also a decision-response mapping cue after the stimulus so as to tease apart the effect of decision from that of motor response. We found that the target detection performance was significantly affected by the probability cue in the current trial and also by the decision in the previous trial. While the information about the target probability modulated the decision criteria, the previous decision modulated the sensitivity to target-relevant sensory signals (d-prime. Using functional magnetic resonance imaging, we also found that activation in the left intraparietal sulcus was decreased when the probability cue indicated a high probability of the target. By contrast, activation in the right inferior frontal gyrus was increased when the subjects made a target-present decision in the previous trial, but this change was observed specifically when the target was present in the current trial. Activation in these regions was associated with individual-difference in the decision computation parameters. We argue that the previous decision biases the target detection performance by modulating the processing of target-selective information, and this mechanism is distinct from modulation of decision criteria due to expectation of a target.

    2013-01-01

    Objective: To develop a scoring system for the prediction of successful vaginal birth after caesarean section, following induction of labour with intra-vaginal E2 gel (Glandin). Methods: The cross-sectional study was conducted from January 2010 to August 2011, at the Pakistan Institute of Medical Sciences in Islamabad. Trial of labour in previous one caesarean section, undergoing induction with intra-vaginal E2 gel, was attempted in 100 women. They were scored according to six variables; maternal age; gestation; indications of previous caesarean; history of vaginal birth either before or after the previous caesarean; Bishop score and body mass index. Multivariate and univariate logistic regression analysis was used to develop the scoring system. Results: Of the total, 67 (67%) women delivered vaginally, while 33 (33%) ended in repeat caesarean delivery. Among the subjects, 55 (55%) women had no history of vaginal delivery either before or after previous caesarean section; 15 (15%) had history of vaginal births both before and after the previous caesarean; while 30 (30%) had vaginal delivery only after the previous caesarean section. Rates of successful vaginal birth after caesarean increased from 38% in women having a score of 0-3 to 58% in patients scoring 4-6. Among those having a score of 7-9 and 10-12, the success rates were 71% and 86% respectively. Conclusion: Increasing scores correlated with the increasing probability of vaginal birth after caesarean undergoing induction of labour. The admission VBAC scoring system is useful in counselling women with previous caesarean for the option of induction of labour or repeat caesarean delivery. (author)

    To evaluate the association between previous splenectomy and gastric dilatation-volvulus (GDV) in dogs. Multi-institutional retrospective case-control study. Animals-151 dogs treated surgically for GDV and 302 control dogs with no history of GDV. Computerized records of dogs evaluated via exploratory laparotomy or abdominal ultrasonography were searched, and dogs with GDV and dogs without GDV (control dogs) were identified. Two control dogs were matched with respect to age, body weight, sex, neuter status, and breed to each dog with GDV. Data were collected on the presence or absence of the spleen for both dogs with GDV and control dogs. Conditional logistic regression analysis was used to investigate the association of previous splenectomy with GDV. 6 (4%) dogs in the GDV group and 3 (1%) dogs in the control group had a history of previous splenectomy. The odds of GDV in dogs with a history of previous splenectomy in this population of dogs were 5.3 times those of dogs without a history of previous splenectomy (95% confidence interval, 1.1 to 26.8). For the patients in the present study, there was an increased odds of GDV in dogs with a history of splenectomy. Prophylactic gastropexy may be considered in dogs undergoing a splenectomy, particularly if other risk factors for GDV are present.

    Anyone who has signed up for cell phone service, attempted to claim a rebate, or navigated a call center has probably suffered from a company's apparent indifference to what should be its first concern: the customer experiences that culminate in either satisfaction or disappointment and defection. Customer experience is the subjective response customers have to direct or indirect contact with a company. It encompasses every aspect of an offering: customer care, advertising, packaging, features, ease of use, reliability. Customer experience is shaped by customers' expectations, which largely reflect previous experiences. Few CEOs would argue against the significance of customer experience or against measuring and analyzing it. But many don't appreciate how those activities differ from CRM or just how illuminating the data can be. For instance, the majority of the companies in a recent survey believed they have been providing "superior" experiences to customers, but most customers disagreed. The authors describe a customer experience management (CEM) process that involves three kinds of monitoring: past patterns (evaluating completed transactions), present patterns (tracking current relationships), and potential patterns (conducting inquiries in the hope of unveiling future opportunities). Data are collected at or about touch points through such methods as surveys, interviews, focus groups, and online forums. Companies need to involve every function in the effort, not just a single customer-facing group. The authors go on to illustrate how a cross-functional CEM system is created. With such a system, companies can discover which customers are prospects for growth and which require immediate intervention.

    The TRIO experiment is a test of in-situ tritium recovery and heat transfer performance of a miniaturized solid breeder blanket assembly. The assembly (capsule) was monitored for temperature and neutron flux profiles during irradiation and a sweep gas flowed through the capsule to an anaytical train wherein the amounts of tritium in its various chemical forms were determined. The capsule was designed to operate at different temperatures and sweep gas conditions. At the end of the experiment the amount of tritium retained in the solid was at a concentration of less than 0.1 wppM. More than 99.9% of tritium generated during the experiment was successfully recovered. The results of the experiment showed that the tritium inventories at the beginning and at the end of the experiment follow a relationship which appears to be characteristic of intragranular diffusion.

  4. Preoperative electrocardiography: its cost-effectiveness in detecting abnormalities when a previous tracing exists.

    Rabkin, S W; Horne, J M

    1979-01-01

    In 812 patients who underwent routine preoperative electrocardiography a mean of 24.6 months after undergoing electrocardiography at the same institution, the frequency of new abnormalities was estimated to evaluate the cost-effectiveness of this procedure prior to an operation. New abnormalities were judged to be either relevant or irrelevant to the assessment of operative risk, depending upon their previously demonstrated correlation with operative and postoperative morbidity and mortality. Since new abnormalities, especially new relevant abnormalities, were found to be relatively infrequent, the cost-effectiveness of routine preoperative electrocardiography was considered to be low. The evidence suggested that when a previous tracing exists preoperative electrocardiography is most clearly indicated for patients who are 60 years of age or older or whose previous tracing exhibited abnormalities. However, further research is required to develop more sensitive and specific protocols, and to evaluate the role of repeat electrocardiography in clinical decision-making. PMID:111793

    Full Text Available Abstract Background Genome-wide linkage studies for Alzheimer's disease have implicated several chromosomal regions as potential loci for susceptibility genes. Methods In the present study, we have combined a selection of affected relative pairs (ARPs from the UK and the USA included in a previous linkage study by Myers et al. (Am J Med Genet, 2002, with ARPs from Sweden and Washington University. In this total sample collection of 397 ARPs, we have analyzed linkage to chromosomes 1, 9, 10, 12, 19 and 21, implicated in the previous scan. Results The analysis revealed that linkage to chromosome 19q13 close to the APOE locus increased considerably as compared to the earlier scan. However, linkage to chromosome 10q21, which provided the strongest linkage in the previous scan could not be detected. Conclusion The present investigation provides yet further evidence that 19q13 is the only chromosomal region consistently linked to Alzheimer's disease.

    Exome Sequencing Project (ESP) has provided important knowledge on this topic. We aimed to investigate the prevalence of previously LQTS-associated variants in ESP (5400 individuals), in order to identify possible false-positive LQTS variants. With this aim, we performed a search for previously...... published LQTS-associated variants in ESP. In addition, a PolyPhen-2 prediction was conducted, and the four most prevalent LQTS-associated variants with significant functional effects present in ESP were genotyped in a second control population. We identified 33 missense variants previously associated...... with LQTS in ESP. These 33 variants affected 173 alleles and this corresponded to a LQTS prevalence of 1:31 in the ESP population. PolyPhen-2 predicted 30% of the 33 variants present in ESP to be benign compared with 13% among LQTS-associated variants not present in ESP (P=0.019). Genotyping of the four...

    Disbelief exits that individuals who have a mental health condition are able to recover and fully function in life. This study analyzed 1,437 adults from the 2006 General Social Survey. Structural equation modeling (1) examined the relationship between respondents' level of prejudicial attitudes and social distance (i.e., stigma) toward individuals who have a mental health condition and their belief in the potential of recovery (2) tested whether previous contact with an individual who received treatment was a mediator. Findings indicated that the belief in recovery led to lower levels of social distance. Prejudicial attitudes were found to be a predictor of one's level of social distance. Previous contact was not a mediator however; males, minorities and those with less education were less likely to have had previous contact. Results indicated a need to emphasize the probability of recovering from a mental health condition when developing target-specific stigma reducing strategies.

    Multiple mating allows females to obtain material (more sperm and nutrient) and/or genetic benefits. The genetic benefit models require sperm from different males to fertilize eggs competitively or the offspring be fathered by multiple males. To maximize genetic benefits from multiple mating, females have evolved strategies to prefer novel versus previous mates in their subsequent matings. However, the reproductive behavior during mate encounter, mate choice and egg laying in relation to discrimination and preference between sexes has been largely neglected. In the present study, we used novel and previous mate treatments and studied male and female behavior and reproductive output in Spodoptera litura. The results of this study do not support the sperm and nutrient replenishment hypotheses because neither the number of mates nor the number of copulations achieved by females significantly increased female fecundity, fertility and longevity. However, females showed different oviposition patterns when facing new versus previous mates by slowing down oviposition, which allows the last male has opportunities to fertilize her eggs and the female to promote offspring diversity. Moreover, females that have novel males present called earlier and more than females that have their previous mates present, whereas no significant differences were found on male courtship between treatments. These results suggest that S. litura females can distinguish novel from previous mates and prefer the former, whereas males generally remate regardless of whether the female is a previous mate or not. In S. litura, eggs are laid in large clusters and offspring competition, inbreeding and disease transfer risks are thus increased. Therefore, offspring diversity should be valuable for S. litura, and genetic benefits should be the main force behind the evolution of female behavioral strategies found in the present study.

    We compare our Monte Carlo reaction rates (see Paper II of this issue) to previous results that were obtained by using the classical method of computing thermonuclear reaction rates. For each reaction, the comparison is presented using two types of graphs: the first shows the change in reaction rate uncertainties, while the second displays our new results normalized to the previously recommended reaction rate. We find that the rates have changed significantly for almost all reactions considered here. The changes are caused by (i) our new Monte Carlo method of computing reaction rates (see Paper I of this issue), and (ii) newly available nuclear physics information (see Paper III of this issue).

    Generation scheduling is a crucial challenge in power systems especially under new environment of liberalization of electricity industry. A new Lagrangian relaxation method for unit commitment (UC) has been presented for solving generation scheduling problem. This paper focuses on the economical aspect of UC problem, while the previous hour scheduling as a very important issue is studied. In this paper generation scheduling of present hour has been conducted by considering the previous hour scheduling. The impacts of hot/cold start-up cost have been taken in to account in this paper. Case studies and numerical analysis presents significant outcomes while it demonstrates the effectiveness of the proposed method.

    This study assessed the role of habits and previous behavior in predicting fruit consumption as well as their additional predictive contribution besides socio-demographic and motivational factors. In the literature, habits are proposed as a stable construct that needs to be controlled for in longitudinal analyses that predict behavior. The aim of this study is to provide empirical evidence for the inclusion of either previous behavior or habits. A random sample of 806 Dutch adults (>18 years) was invited by an online survey panel of a private research company to participate in an online study on fruit consumption. A longitudinal design (N = 574) was used with assessments at baseline and after one (T2) and two months (T3). Multivariate linear regression analysis was used to assess the differential value of habit and previous behavior in the prediction of fruit consumption. Eighty percent of habit strength could be explained by habit strength one month earlier, and 64% of fruit consumption could be explained by fruit consumption one month earlier. Regression analyses revealed that the model with motivational constructs explained 41% of the behavioral variance at T2 and 38% at T3. The addition of previous behavior and habit increased the explained variance up to 66% at T2 and to 59% at T3. Inclusion of these factors resulted in non-significant contributions of the motivational constructs. Furthermore, our findings showed that the effect of habit strength on future behavior was to a large extent mediated by previous behavior. Both habit and previous behavior are important as predictors of future behavior, and as educational objectives for behavior change programs. Our results revealed less stability for the constructs over time than expected. Habit strength was to a large extent mediated by previous behavior and our results do not strongly suggest a need for the inclusion of both constructs. Future research needs to assess the conditions that determine direct

    Updated results are given for nine asteroids previously reported from the Palmer Divide Observatory (PDO). The original images were re-measured to obtain new data sets using the latest version of MPO Canopus photometry software, analysis tools, and revised techniques for linking multiple observing runs covering several days to several weeks. Results that were previously not reported or were moderately different were found for 1659 Punkajarju, 1719 Jens, 1987 Kaplan, 2105 Gudy, 2961 Katsurahama, 3285 Ruth Wolfe, 3447 Burckhalter, 7816 Hanoi, and (34817) 2000 SE116. This is one in a series of papers that will examine results obtained during the initial years of the asteroid lightcurve program at PDO.

    The immune response of lambs infected with the lungworm, Dictyocaulus filaria to vaccination with the radiation attenuated D.filaria vaccine was studied under experimental conditions. Healthy, un-infected lambs, 4-6 months of age were randomly distributed into three groups. Group one lambs were previously exposed to single or trickle infections of D.filaria before being vaccinated, group two lambs were vaccinated only whereas the group three lambs received neither infection nor were vaccinated. All the lambs were subsequently challanged with normal infective D.filaria larvae. The results of the experiment indicate that the vaccine confers very little or practically no immunity in lambs already exposed to the infection. The significance of these findings in the use of the vaccine for the control of lungworm disease in sheep under field conditions is discussed. (author)

  20. Mixture Experiments

    Energy Technology Data Exchange (ETDEWEB)

    Piepel, Gregory F.

    2007-12-01

    A mixture experiment involves combining two or more components in various proportions or amounts and then measuring one or more responses for the resulting end products. Other factors that affect the response(s), such as process variables and/or the total amount of the mixture, may also be studied in the experiment. A mixture experiment design specifies the combinations of mixture components and other experimental factors (if any) to be studied and the response variable(s) to be measured. Mixture experiment data analyses are then used to achieve the desired goals, which may include (i) understanding the effects of components and other factors on the response(s), (ii) identifying components and other factors with significant and nonsignificant effects on the response(s), (iii) developing models for predicting the response(s) as functions of the mixture components and any other factors, and (iv) developing end-products with desired values and uncertainties of the response(s). Given a mixture experiment problem, a practitioner must consider the possible approaches for designing the experiment and analyzing the data, and then select the approach best suited to the problem. Eight possible approaches include 1) component proportions, 2) mathematically independent variables, 3) slack variable, 4) mixture amount, 5) component amounts, 6) mixture process variable, 7) mixture of mixtures, and 8) multi-factor mixture. The article provides an overview of the mixture experiment designs, models, and data analyses for these approaches.
