Virtual parental presence with coaching for reducing preoperative anxiety in children: a feasibility and pilot randomized controlled trial.

BACKGROUND: Preoperative anxiety in children causes negative postoperative outcomes. Parental presence at induction is a non-pharmacological strategy for relieving anxiety; nevertheless, it is not always possible or effective, namely when parents are overly anxious. Parental presence via video has been demonstrated to be useful in other contexts (divorce, criminal court). This study reports the feasibility of a randomized controlled trial to investigate the effect of video parental presence and parental coaching at induction on preoperative anxiety. METHODS: The study was a randomized, 2 × 2 factorial design trial examining parental presence (virtual vs. physical) and coaching (provided vs. not provided). Feasibility was assessed by enrollment rate, attrition rate, compliance, and staff satisfaction with virtual method with the NASA-Task Load Index (NASA-TLX) and System Usability Scale (SUS). For the children's anxiety and postoperative outcomes, the modified Yale Preoperative Anxiety Scale (mYPAS) and Post-Hospitalization Behavioral Questionnaire (PHBQ) were used. Parental anxiety was evaluated with the State-Trait Anxiety Inventory (STAI) questionnaire. RESULTS: A total of 41 parent/patient dyads were recruited. The enrollment rate was 32.2%, the attrition rate 25.5%. Compliance was 87.8% for parents and 85% for staff. The SUS was 67.5/100 and 63.5/100 and NASA-TLX was 29.2 (21.5-36.8) and 27.6 (8.2-3.7) for the anesthesiologists and induction nurses, respectively. No statistically significant difference was found in mYPAS, PHBQ and STAI. CONCLUSION: A randomized controlled trial to explore virtual parental presence effect on preoperative anxiety is feasible. Further studies are needed to investigate its role and the role of parent coaching in reducing preoperative anxiety.

How Do Escape Distance Behavior of Broiler Chickens Change in Response to a Mobile Robot Moving at Two Different Speeds?

In poultry farming, robots are considered by birds as intruder elements to their environment, because animals escape due to their movement. Their escape is measured using the escape distance (ED) technique. This study analyzes the behavior of animals in relation to their ED through the use of a robot with two speeds: 12 rpm and 26 rpm. The objective is to understand whether the speeds cause variations in ED and their implications for animal stress. A broiler breeding cycle was analyzed (six weeks) through the introduction of the robot weekly. ED analyses were carried out on static images generated from footage of the robot running. The results indicate higher escape distance rates (p < 0.05) peaking midway through the production cycle, notably in the third week. Conversely, the final weeks saw the lowest ED, with the most significant reduction occurring in the last week. This pattern indicates a gradual escalation of ED up to the fourth week, followed by a subsequent decline. Despite RPM12 having shown low ED results, it did not show enough ED to move the animals away from their path of travel, causing bumps and collisions. RPM26 showed higher ED in all breeding phases, but showed ED with no bumps and collisions.

Perceived instructor presence, interactive tools, student engagement, and satisfaction in hybrid education post-COVID-19 lockdown in Mexico.

Interactive communication platforms have been widely used to support online teaching. However, during the Coronavirus Diseases 2019 (COVID-19) pandemic they gained unprecedented relevance since they allowed educational processes to continue. This study investigated the relationship among interactive communication technology tools, perceived instructor presence, student satisfaction and engagement in hybrid courses post-COVID-19 lockdown. An electronic questionnaire was administered to 1086 students from a public university in Mexico that implemented a hybrid class model using Microsoft Teams after the lockdown. Jamovi and WarpPLS were used to perform confirmatory factor analysis and structural equation modeling. The findings revealed that interactive technological communication tools positively impact the instructor's perceived presence, student satisfaction and engagement. Similarly, commitment significantly positively impacted student satisfaction. The model demonstrated a good fit. The findings were consistent with studies before and during the lockdown. The instructor's perceived presence promotes student engagement and satisfaction, and Microsoft Teams effectively facilitates this presence. These findings suggest that interactive communication tools are and will be significant in educational contexts and modalities. This study provides useful insights for educators, course designers and educational administrators, emphasizing effective communication with students and implementing interactive technological communication tools to enhance hybrid learning in the post-pandemic era.

Factors intrinsic to handling and transport in pre-slaughter behavioural changes in beef cattle.

The aim of this study was to evaluate handling and transport variables as potential causes of disturbed behaviour in response to seeing a person on an overhead observation platform during pre-slaughter in batches of females and castrated males composed of pure or crossed Bos Taurus animals (Aberdeen Angus, Red Angus, Hereford and Charolais) with a maximum of 37.5% Bos indicus, and maturity at slaughter varying from zero to eight teeth, coming from pasture and confined systems. For the batches of castrated males, the independent variables included the distance covered on the trip, and the handling and facilities on the farms. For the female batches, the variables were travel time and waiting time prior to unloading. For both sexes, the presence of horns in the batches and the load density were included in the regression equations. Disturbed behaviour, the result of factors related to animal handling and transportation, is detrimental to satisfactory results in production systems. It is up to the managers in the production chain to seek alternatives in order to minimise inappropriate behaviour, which is one determinant of loss. Handling and transport are determining factors in the behaviour of beef cattle during the pre-slaughter period.

A experiência do distanciamento social: entre presenças, ausências e sentidos / The experience of social distancing: between presences, absences and senses / La experiencia del distanciamento social: entre presencias, ausencias y sentidos

O presente ensaio teórico buscou discutir as transformações que a experiência de distanciamento social, em decorrência da pandemia do novo coronavírus, tem operado nas formas de produção compartilhada de sentidos. Para tal, utilizamos as contribuições da abordagem enativa da cognição sobre o conceito de produção de sentidos. As noções de presença e ausência, como dimensões coproduzidas e relevantes nas vivências coletivas do último período permearam toda a reflexão. Compreendemos o sentido como uma realização incorporada que movimenta e mantém a vida e sua rede de relações, de modo que não é produzido apenas individualmente, mas também participativamente. Avançamos na discussão sobre a experiência corporal de ausências, destacando a solidão no aspecto que compreendemos aqui como ausência de produção compartilhada de sentidos. Como resposta à ausência do outro, as interações por internet ganharam relevância. Discutimos as presenças mediadas tecnologicamente, dando ênfase ao papel das redes sociais no cotidiano, às formas de produzir sentidos participativamente neste contexto, atenuando as emoções de ausência, mas por outro lado intensificando sofrimentos específicos gerados por esse modo de se relacionar e produzir subjetividade. Concluímos apontando para a diversidade de formas de experienciar os efeitos da pandemia, inclusive ressalvando que não apenas as ausências provocaram sofrimento neste período, mas também algumas presenças, causando sobrecarga pelas demandas de cuidado.(AU)

This theoretical essay sought to discuss the transformations that the experience of social distancing due to the pandemic of the new coronavirus has operated in the forms of participatory sense-making. To this end, we use contributions from the enactive approach to cognition on the concept of sense-making. The notions of presence and absence, as coproduced and relevant dimensions in the collective experiences of the last period, permeated all reflection. We understand the sense as an embodied realization that moves and maintains life and its network of relationships, so that it is produced not only individually, but also participatively. We advanced in the discussion about the bodily experience of absences, highlighting loneliness in the aspect that we understand here as the absence of participatory sense-making. In response to the absence of the other, internet interactions have gained relevance. We discussed the presences technologically mediated, emphasizing the role of social media in everyday life, the ways of participatory sensemaking in this context, attenuating the emotions of absence, but on the other hand intensifying specific sufferings generated by this way of relationship and producing subjectivity. We conclude by pointing to the diversity of ways of experiencing the effects of the pandemic, including that not only the absences caused suffering in this period, but also some presences, causing overload by care demands.(AU)

Occurrence Prediction of Riffle Beetles (Coleoptera: Elmidae) in a Tropical Andean Basin of Ecuador Using Species Distribution Models.

Genera and species of Elmidae (riffle beetles) are sensitive to water pollution; however, in tropical freshwater ecosystems, their requirements regarding environmental factors need to be investigated. Species distribution models (SDMs) were established for five elmid genera in the Paute river basin (southern Ecuador) using the Random Forest (RF) algorithm considering environmental variables, i.e., meteorology, land use, hydrology, and topography. Each RF-based model was trained and optimised using cross-validation. Environmental variables that explained most of the Elmidae spatial variability were land use (i.e., riparian vegetation alteration and presence/absence of canopy), precipitation, and topography, mainly elevation and slope. The highest probability of occurrence for elmids genera was predicted in streams located within well-preserved zones. Moreover, specific ecological niches were spatially predicted for each genus. Macrelmis was predicted in the lower and forested areas, with high precipitation levels, towards the Amazon basin. Austrelmis was predicted to be in the upper parts of the basin, i.e., páramo ecosystems, with an excellent level of conservation of their riparian ecosystems. Austrolimnius and Heterelmis were also predicted in the upper parts of the basin but in more widespread elevation ranges, in the Heterelmis case, and even in some areas with a medium level of anthropisation. Neoelmis was predicted to be in the mid-region of the study basin in high altitudinal streams with a high degree of meandering. The main findings of this research are likely to contribute significantly to local conservation and restoration efforts being implemented in the study basin and could be extrapolated to similar eco-hydrological systems.

Influence of Hand Tracking in Immersive Virtual Reality for Memory Assessment.

Few works analyze the parameters inherent to immersive virtual reality (IVR) in applications for memory evaluation. Specifically, hand tracking adds to the immersion of the system, placing the user in the first person with full awareness of the position of their hands. Thus, this work addresses the influence of hand tracking in memory assessment with IVR systems. For this, an application based on activities of daily living was developed, where the user must remember the location of the elements. The data collected by the application are the accuracy of the answers and the response time; the participants are 20 healthy subjects who pass the MoCA test with an age range between 18 to 60 years of age; the application was evaluated with classic controllers and with the hand tracking of the Oculus Quest 2. After the experimentation, the participants carried out presence (PQ), usability (UMUX), and satisfaction (USEQ) tests. The results indicate no difference with statistical significance between both experiments; controller experiments have 7.08% higher accuracy and 0.27 ys. faster response time. Contrary to expectations, presence was 1.3% lower for hand tracking, and usability (0.18%) and satisfaction (1.43%) had similar results. The findings indicate no evidence to determine better conditions in the evaluation of memory in this case of IVR with hand tracking.

Presenteeism and noise perception at work: a cross-sectional study using association analysis

ABSTRACT BACKGROUND: Presenteeism refers to the presence of a worker at work with reduced performance due to illness, and it is a common public health problem. Exposure to noise during production processes brings risk to workers' health. OBJECTIVE: To analyze the health profile of workers in the automotive industry and identify the association between noise perception and presenteeism among workers in the Brazilian automotive industry. DESIGN AND SETTING: This was a cross-sectional study utilizing a case study design analyzing the automotive industry in the interior of São Paulo state, Brazil. METHODS: This study included 306 workers using the Presenteeism Work Limitations Questionnaire protocol. Multiple logistic regression was used for data analysis. RESULTS: Male workers with reports of headache, tension, and limited well-being at work, having perceived that noise exposure interferes with productivity, showed a positive association with the occurrence of presenteeism. Physical demand had the highest score in terms of interfering with the presenteeism index. CONCLUSION: Workers' perceptions of noise were associated with presenteeism.

Bird species occupancy trends in Southeast Mexico over 1900-2020: Accounting for sighting record absences.

Long-term land-use change impacts tropical bird communities through population-level and functional diversity effects from habitat loss, degradation and fragmentation, leading to land management and conservation challenges. Assessing the temporal impacts of land-use change on occupancy patterns, population change and functional traits of bird species in tropical areas is limited by the treatment of nondetections as true absences or artefacts of low sampling effort during and throughout years. With this in mind, we developed a novel Bayesian species occupancy framework to account for species absences to evaluate bird community changes in Palenque, Chiapas, Mexico, where there is opportunity for study given exceptional records of change across habitats from rainforest to urban centres. We created a novel dataset of population trends for 244 bird species over the years 1900 to 2020 from published short-term field studies, expert field notes and community science pages. Our results show that open area species had higher population increases than forest specialists over time, represented most evidently by the turnover of rainforest specialists for urban species. Modelled influence of functional traits displayed the importance of main habitat types, body mass and habitat and dietary breadth as factors that associated with bird population trends. On average, species with body masses <6.6 and > 948.4 g showed decreasing trends, while all other species showed increasing or stable trends. Our findings illuminate the value of accounting for species absences from several data sources to discover long-term species population trends and affiliated functional traits whose preservation requires conservation and land management action to protect bird ecosystem services. Primary forest conservation is key to maintaining populations of habitat and dietary specialists, such as small understorey insectivorous and large frugivorous species. Protecting rare natural savanna patches from conversion to cattle pasture is vital to prevent further extirpation of native granivores and to slow colonization by exotic and invasive species.

El cambio a largo plazo en el uso de la tierra impacta a las comunidades de aves tropicales a través de los efectos de la diversidad funcional y a nivel de la población debido a la pérdida, degradación y fragmentación del hábitat, lo que lleva a desafíos de gestión y conservación de la tierra. La evaluación de los impactos temporales del cambio de uso de la tierra en los patrones de ocupación, el cambio de población y los rasgos funcionales de las especies de aves en áreas tropicales enfrenta limitaciones al considerar el tratamiento de las no detecciones como ausencias verdaderas o artefactos de bajo esfuerzo de muestreo durante el año y los años. La evaluación de los impactos temporales del cambio de uso de la tierra en los patrones de ocupación, el cambio de población y las características funcionales de las especies de aves en áreas tropicales está limitada por el tratamiento de las no detecciones como verdaderas ausencias o artefactos de bajo esfuerzo de muestreo durante y a lo largo de los años. Con esto en mente, desarrollamos un marco bayesiano novedoso de ocupación de especies para dar cuenta de las ausencias de especies para evaluar los cambios en la comunidad de aves en Palenque, Chiapas, México, donde existe la oportunidad de estudiar dados los registros excepcionales de cambios en los hábitats, desde la selva tropical hasta los centros urbanos. Creamos un nuevo conjunto de datos de tendencias de población para 244 especies de aves durante los años 1900 a 2020 a partir de estudios de campo a corto plazo publicados, notas de campo de expertos y páginas de ciencia comunitaria. Nuestros resultados muestran que las especies de áreas abiertas tuvieron aumentos de población más altos que los especialistas forestales a lo largo del tiempo, representado más evidentemente por la rotación de especialistas de bosques tropicales por especies urbanas. La influencia modelada de los rasgos funcionales mostró la importancia de los principales tipos de hábitat, la masa corporal y el hábitat y la amplitud de la dieta como factores asociados con las tendencias de la población de aves. En promedio, las especies con masas corporales <6,6 g y >948,4 g mostraron tendencias decrecientes, mientras que todas las demás especies mostraron tendencias crecientes o estables. Nuestros hallazgos iluminan el valor de contabilizar las ausencias de especies de varias fuentes de datos para descubrir tendencias de población de especies a largo plazo y rasgos funcionales afiliados cuya preservación requiere acción de conservación y manejo de la tierra para proteger los servicios ecosistémicos de las aves. La conservación de los bosques primarios es clave para mantener las poblaciones de especialistas en hábitat y dieta, como las especies insectívoras pequeñas del sotobosque y las especies frugívoras grandes. Proteger los raros parches naturales de sabana de la conversión en pastos para ganado es vital para evitar una mayor extirpación de los granívoros nativos y para retrasar la colonización por especies invasoras.

Meaning of life questionnaire (MLQ) in peruvian undergraduate students: study of its psychometric properties from the perspective of classical test theory (CTT).

BACKGROUND: The study of the meaning of life is essential since it plays a protective role in the mental health of university students. However, no studies have shown the adequate psychometric functioning of the MLQ in Latin American university students. For this reason, this research aims to evaluate the internal structure using CTT models, obtain evidence of validity based on the relationship with other variables, perform factorial invariance according to gender, and estimate the reliability of the MLQ. METHODS: A sample of 581 Peruvian undergraduate students of both sexes (29.5% men and 70.5% women) between the ages of 18 and 35 (M = 22.6; SD = 3.3) was collected. Along with the MLQ, other instruments were applied to measure satisfaction with life (SWLS), subjective well-being (WBI), and depression (PHQ-9). RESULTS: In the present study was evidenced that the model of two related factors of nine items presents better adjustment indices (RMSEA = .075; SRMR = .059; CFI = .97; TLI = .96) compared to other models. Also, it was shown that the factorial structure of the MLQ is strictly invariant for the group of men and women. It was also shown that the presence of meaning was positively related to satisfaction with life (.63) and well-being (.60) and negatively to depression (- .56). In contrast, the search for meaning was not significantly related to life satisfaction (- .05) and well-being (- .07); but yes, to depression (.19). CONCLUSION: It is concluded that the MLQ from the perspective of CTT has shown adequate evidence of reliability and validity. Therefore, it could be used in future studies and evaluation and intervention processes. In addition, the study provides the first evidence of the psychometric functioning of the scale in university students from Latin America.

Teaching Presence vs. Student Perceived Preparedness for Testing in Higher Education Online English Courses During a Global Pandemic? Challenges, Tensions, and Opportunities.

In the context of a global pandemic that started in 2020, the Chilean higher education institution Universidad Andrés Bello (UNAB) faced the challenge of giving continuity to its already established blended program for English courses while also starting the implementation of a high-stakes certification assessment for its students using the Test of English for International Communication (TOEIC) Bridge. This study sought to evaluate how much of a mediating factor online teaching presence could be in the context of test preparation within a language course in aspects related to autonomous learning and perceived learning outcomes. A mixed-methods approach was used. It included a survey applied to 1,642 eligible students of the English program. These quantitative data were complemented with students' comments and teacher interviews. After triangulating quantitative and qualitative data, teaching presence was clearly perceived to be a relevant aspect of the online experience in the studied courses. However, both students' and teachers' voices evidenced pervasive challenges and tensions that hinder the potentially transformative benefits that online learning is expected to bring about.

On Love, Dying Alone, and Community.

This paper examines the problem of dying alone in the context of no-visitors hospital policy during the COVID-19 pandemic. It critically analyses a rights-based solution, offering a democratized visitors policy alternative, premised on the value of legal justice. While an inclusive, participatory, and thoroughly justified visitors' policy, which takes into account the good of all stakeholders in the process, is indeed the right alternative to the paternalistic, top-down no-visitors policy, I argue that the democratized visitors' policy alternative ought to be grounded on reasons of both justice and love. Legal justice and claimable individual rights, though important, are limited and cannot fully capture the vicissitudes of mutual vulnerabilities and the moral stringency of duties of mutual care. In the context of suffering and death, instances of extreme vulnerability and interdependence, individual rights of autonomy and self-determination prove insufficient to meet our most basic needs for love, human presence, and accompaniment.

Seasonal and diel influences on bottlenose dolphin acoustic detection determined by whistles in a coastal lagoon in the southwestern Gulf of California.

Marine mammals in subtropical coastal habitats are sentinels of the health of the ecosystem and offer important ecosystem services. They rely on prey that pursues feeding opportunities, while both avoid unfavorable conditions. In many cases, these predator-prey dynamics fluctuate seasonally and are regulated by lunar, tidal, and/or diel cycles (hour). However, these rhythmical patterns may vary under different seasonal conditions. Bottlenose dolphins (Tursiops truncatus) in the Ensenada de La Paz in Baja California Sur, Mexico, were detected acoustically over the course of an annual cycle on 21 separate occasions, covering 640 h from June 2017 to May 2019. The presence of bottlenose dolphins was examined using Generalized Additive Models (GAM) including variables that are related directly to their habitat (direct variables: hour, distance, depth) and to their prey (indirect variables: SST, moon phase and tides). Seasonal differences in the presence of bottlenose dolphins were influenced more by indirect variables (explained deviance: 34.8% vs. 37.7%). Hourly acoustic detections occurred less frequently when SST exceeded 27.4 °C (Aug-End of Nov.) and more frequently at moderate temperatures (22.7 °C to 26.3 °C) in May through July. Moreover, bottlenose dolphins were detected more frequently during waning and new moon phases, at the onset of flood and ebb tides, and during day (04:00 to 20:00). The seasonal differences in acoustic detections rates were highlighted by the global GAM and hierarchical clustering. The strong seasonal pattern indicated possible interactions with rhythmic pattern of bottlenose dolphins. Four candidate variables (SST, moon, tide, and hour) were tested for plausible interaction terms additional to their individual consideration, out of which only hour changed significantly between seasons. The patterns of presence likely increase feeding opportunities or may favor other behaviors such as socializing, resting, or nursing. These might prove responsible for the distinct occurrence and hourly patterns of bottlenose dolphins.

Integrating presence-only and occupancy data to model habitat use for the northernmost population of jaguars.

Species distribution models (SDMs) have become an essential tool for the management and conservation of imperiled species. However, many at-risk species are rare and characterized by limited data on their spatial distribution and habitat relationships. This has led to the development of SDMs that integrate multiple types and sources of data to leverage more information and provide improved predictions of habitat associations. We developed a novel integrated species distribution model to predict habitat suitability for jaguars (Panthera onca) in the border region between northern Mexico and the southwestern USA. Our model combined presence-only and occupancy data to identify key environmental correlates, and we used model results to develop a probability of use map. We adopted a logistic regression modeling framework, which we found to be more straightforward and less computationally intensive to fit than Poisson point process-based models. Model results suggested that high terrain ruggedness and the presence of riparian vegetation were most strongly related to habitat use by jaguars in our study region. Our best model, on average, predicted that there is currently 25,463 km2 of usable habitat in our study region. The United States portion of the study region, which makes up 38.6% of the total area, contained 40.6% of the total usable habitat. Even though there have been few detections of jaguars in the southwestern USA in recent decades, our results suggest that protection of currently suitable habitats, along with increased conservation efforts, could significantly contribute to the recovery of jaguars in the USA.

Focusing on cybersickness: pervasiveness, latent trajectories, susceptibility, and effects on the virtual reality experience.

Although virtual reality (VR) usage has become widespread in the last decade, its adoption has been hampered by experiences of user discomfort known as cybersickness. The present study, in line with the "2020 cybersickness R&D agenda", sought to provide a broad examination of the cybersickness phenomenon, assessing its pervasiveness, latent trajectories, impacts on the VR experience, and predictor variables. The study was composed of 92 participants living in the Dominican Republic with ages ranging from 18 to 52 years (M = 26.22), who experienced a 10-min VR immersion in two environments designed for psychotherapy. The results indicated that cybersickness was pervasive, with 65.2% of the participants experiencing it, and 23.9% severely. Additionally, the latent trajectories of cybersickness were positive and curvilinear, with large heterogeneity across individuals. Cybersickness also had a substantive negative impact on the user experience and the intentions to adopt the VR technology. Finally, motion sickness susceptibility, cognitive stress, and recent headaches uniquely predicted greater severity of cybersickness, while age was negatively related. These combined results highlight the critical role that cybersickness plays on the VR experience and underscore the importance of finding solutions to the problems, such as technological advancements or special usage protocols for the more susceptible individuals.

Presença comum: dispositivos para invenção na formação em Saúde / Common presence: invention devices in health education and training / Presencia común: dispositivos para invención en la formación en salud

Movidos pelo desejo de arriscar a invenção com o que se tinha à mão, realizamos um projeto de pesquisa e extensão universitária denominado Metodologias da Presença para estudantes em formação da área da Saúde. Tratou-se de uma plataforma remota de criação para encorajar os participantes a produzir e compartilhar exercícios artísticos por meio de três ativações de presença. Esta experiência contou com a participação de uma comunidade provisória. Impulsionados pela prática limiar pedagógica e artística, seguimos indagando como foi possível a instauração desse estado sensível e vitalizador no grupo? Que tipos de composição impulsionaram as transformações singulares e coletivas mediante a materialização das produções artísticas? Quais as distintas qualidades de presença que puderam ser ali mobilizadas? A produção artística, a presença comum e a construção de grupalidade podem existir em comunicações tecnomediadas na formação em Saúde?(AU)

Driven by the desire to take the risk of inventing with what is at hand, we conducted a research and university outreach project for health students called "Methodologies of Presence". We developed a remote content creation platform to encourage participants to produce and share artistic exercises from three presence activations. The experience included the participation of a temporary community. Propelled by threshold pedagogical and artistic practice, we inquired how was it possible to establish this sensitive and vitalizing state within the group. What types of composition drove the singular and collective transformations spurred by the materialization of artistic productions? Which different qualities of presence were mobilized? Can artistic production, common presence, and the construction of groupality exist within techno-mediated communications in health education and training?(AU)

Epidemiology of Neospora caninum infection in free-range chickens (Gallus gallus domesticus) in north central Mexico.

The objective of the present study was to investigate the epidemiology of natural infection by N. caninum in free-range chickens from Aguascalientes, Mexico, through identifying the presence of antibodies, its association with certain risk factors, and estimate the frequency of parasite DNA detection in the brain. The study included 150 clinically healthy chickens from 81 small family farms distributed throughout the state, from which blood and brain samples were taken. Serum samples were processed by indirect immunofluorescence considering a dilution of 1:50 as a positive reaction, while the DNA detection was done by PCR; the association between the presence of antibodies and the potential risk factors was estimated through logistic regression. The general anti-N. caninum presence of antibodies in the studied population was 46% (69/150, CI 95% 38-54), with titers of 1:50 in 38, 1:100 in 24, and 1:200 in 7, finding positive cases in 49% of the farms and in 91% of the municipalities that integrate the state. The presence of antibodies found in the municipalities was estimated in a range of 20 to 75%. The frequency of DNA detection was 6% (9/150, CI 95% 2-11). The grain supplementation was identified as the unique risk factor for infection (OR = 2.82; 95% CI, 1.18-6.73, p < 0.019).

Memória da presença e desenvolvimento emocional em Winnicott / Presence memory and emotional development in Winnicott

O presente artigo busca mostrar como a constituição do si mesmo winnicottiano está ancorada na experiência de sustentação oportunizada por um ambiente suficientemente bom. Ambiente que se inscreve na experiência do bebê como uma memória da presença, assim designada por nós. Essa memória da presença constitui-se nas marcas da presença materna que o bebê já é capaz de sentir e confiar, pelas repetidas experiências em que ele pôde se retirar do mundo "objetivo" tranquilamente, retornando ao seu mundo subjetivo, no descanso e relaxamento propiciados por um ambiente adaptado à sua necessidade de criação do mundo, vivendo a ilusão de onipotência na relação primitiva mãe-bebê. Discutimos ainda como o paciente constituído pela memória da presença poderá apresentar necessidades especificas na clínica, por meio da regressão à dependência.

This paper aims to show how the constitution of the Winnicottian self is grounded on the experience of support that is made possible by a good enough environment. This environment gets inscribed into the baby's experience as a memory of presence, as we call it. The memory of presence comprises marks of a mother's presence, which babies can already feel and trust, and which repeatedly allows them to make themselves calmly absent from the "objective" world, thus returning to their subjective world at state of rest and relaxation. This is rendered possible by an environment adapted to the baby's need for the creation of a world, while living under the illusion of omnipotence in the primitive mother-baby relationship. The paper also discusses how the patient constituted by the memory of presence may exhibit specific needs while in clinical sessions, by regressing to dependency.
