Reducing CLABSI through a quality strategy for the implementation of the aseptic non-touch technique in a pediatric ward / Reducción de infecciones relacionadas con catéteres venosos centrales por medio de una estrategia de calidad para la implementación de la técnica aséptica «no tocar¼ en una sala de pediatría

Abstract Background: Central line-associated bloodstream infections (CLABSIs) are among the most epidemiologically relevant health care-associated infections. The aseptic non-touch technique (ANTT) is a standardized practice used to prevent CLABSIs. In a pediatric hospital, the overall CLABSI rate was 1.92/1000 catheter days (CD). However, in one unit, the rate was 5.7/1000 CD. Methods: Nurses were trained in ANTT. For the implementation, plan-do-study-act (PDSA) cycles were completed. Adherence monitoring of the ANTT and epidemiological surveillance were performed. Results: ANTT adherence of 95% was achieved after 6 PDSA cycles. Hand hygiene and general cleaning reached 100% adherence. Port disinfection and material collection had the lowest adherence rates, with 76.2% and 84.7%, respectively. The CLABSI rate decreased from 5.7 to 1.26/1000 CD. Conclusion: The implementation of ANTT helped reduce the CLABSI rate. Training and continuous monitoring are key to maintaining ANTT adherence.

NeuroSense: A non-invasive and configurable somatosensory stimulator with OPENVIBE communication.

Understanding the somatosensory system and its abnormalities requires the development of devices that can accurately stimulate the human skin. New methods for assessing the somatosensory system can enhance the diagnosis, treatments, and prognosis for individuals with somatosensory impairments. Therefore, the design of NeuroSense, a tactile stimulator that evokes three types of daily life sensations (touch, air and vibration) is described in this work. The prototype aims to evoke quantitative assessments to evaluate the functionality of the somatosensory system and its abnormal conditions that affect the quality of life. In addition, the device has proven to have varying intensities and onset latencies that produces somatosensory evoked potentials and energy desynchronization on somatosensory cortex.

Comparison of Proparacaine, Tetracaine, and Oxybuprocaine in Corneal Sensitivity Measurement.

Purpose: This study aimed to determine the onset and duration of action of 3 commercially available topical anesthetic solutions in Brazil, using the Cochet-Bonnet esthesiometer (Luneau®, Paris, France) and to quantitatively assess patient-reported discomfort during application. Methods: A prospective, randomized, masked, and double-blind study was conducted, involving 40 eyes from 21 patients. Patients were administered each one of the topical anesthetics weekly, and corneal sensitivity was measured using the Cochet-Bonnet esthesiometer's corneal touch threshold (CTT). Patients rated the burning sensation using a visual analogue scale (VAS). Results: Among the 21 patients (42.9% male), with a mean age of 31.95 years (±standard deviation = 10.17, range = 22.0-58.0), corneal sensitivity significantly decreased 30 s after application, returning to baseline after 30 min for all groups (P < 0.0001). Significant differences in CTT were observed at 5 min, with proparacaine exhibiting a superior anesthetic effect (P = 0.0003), at 10 min, where tetracaine displayed the most substantial anesthetic effect (P = 0.0135), and at 20 min, where tetracaine demonstrated the highest anesthetic efficacy (P < 0.0001). VAS scores indicated the most intense burning sensation with tetracaine (P < 0.0001). Men reported experiencing more discomfort during instillation compared with women (P = 0.0168). Conclusions: Proparacaine exhibited the fastest onset of action among the 3 topical anesthetics and provided a more comfortable eye sensation during instillation. However, tetracaine demonstrated the longest duration of action despite causing more discomfort.

Modulation of facial muscle responses by another person's presence and affiliative touch during affective image viewing.

Stimulating CT-afferents by forearm caresses produces the subjective experience of pleasantness in the receiver and modulates subjective evaluations of viewed affective images. Receiving touch from another person includes the social element of another person's presence, which has been found to influence affective image evaluations without involving touch. The current study investigated whether these modulations translate to facial muscle responses associated with positive and negative affect across touch-involving and mere presence conditions. Female participants (N = 40, M(age) = 22.4, SD = 5.3) watched affective images (neutral, positive, negative) while facial electromyography was recorded (sites: zygomaticus, corrugator). Results from ANOVAs showed that providing touch to another person or oneself modulated zygomaticus site responses when viewing positive images. Providing CT-afferent stimulating touch (i.e., forearm caresses) to another person or oneself dampened the positive affective facial muscle response to positive affective images. Providing touch to another person generally increased corrugator facial muscle activity related to negative affect. Receiving touch did not modulate affective facial muscle responses during the viewing of affective images but may have effects on later cognitive processes. Together, previously reported social and touch modulations of subjective evaluations of affective images do not translate to facial muscle responses during affective image viewing, which were differentially modulated.

Abstract Objective To assess the effectiveness of a Reiki protocol on anxiety levels in the preoperative period of cardiac surgery. Methods This is a controlled and randomized clinical trial carried out in a university reference hospital in cardiology between June and December 2021. Chunk randomization and allocation by draw with opaque sealed envelopes were carried out in two groups: Control (n=44; not subjected to intervention); and Intervention (n=44; submitted to two Reiki sessions three days before and the day before surgery). The main outcomes (anxiety, well-being and muscle tension) were assessed across sessions using a mixed effects model. To assess the effect size, partial eta squared (η2p) values were calculated. Results Differences in anxiety scores (+2.7 points more than the control), well-being (-0.78) and muscle tension (1.27) were determined, being considered statistically significant (p<0.001). In analyzing the effect size, the experiment better distinguished the variation in the anxiety variable (η2p=0.74) than in the other two variables (η2p=0.14; η2p=0.23). Conclusion The study offers favorable evidence for the effectiveness of Reiki in controlling preoperative anxiety after cardiac surgery. Brazilian Clinical Trials Registry: RBR-2nhgvn6

Performance of non-formalin fixed paraffin embedded samples in hybrid capture and amplicon next-generation sequencing panels.

BACKGROUND: Genomic profiling using next-generation sequencing (NGS) is fundamental for driving prognostic and therapy in cancer. Formalin-fixed paraffin embedded (FFPE) tissue is the widely used material, whereas non-FFPE may represent an alternative. However, studies comparing the NGS performance of non-FFPE materials to FFPE are still lacking in the literature. The objective of this study was to characterize in non-FFPE preparations the nucleic acid yield and NGS performance on both a capture-based and an amplicon-based NGS platform. NGS quality metrics obtained from non-FFPE preparations were compared to FFPE. METHODS: We analyzed the cellularity and nucleic acid yield in 111 tumors from non-FFPE preparations. In addition, comprehensive hybrid capture panel sequencing metrics obtained from DNA and RNA libraries were compared between independent non-FFPE and FFPE samples. A paired comparison between non-FFPE and FFPE samples was performed to analyze concordance in mutant allele detection using an amplicon panel. RESULTS: The mean target coverage from DNA libraries was 2× higher in non-FFPE samples than in FFPE. The detection of exogenous DNA was 2.5× higher in non-FFPE than in FFPE. Conversely, a lower performance was observed in non-FFPE RNA libraries in comparison to FFPE DNA libraries with no impact in minimum standard cutoffs. The variant allele detection in non-FFPE was found to be comparable to that of FFPE tumor samples in matched samples. CONCLUSIONS: Non-FFPE was demonstrated to be a suitable material for DNA and RNA library preparations using a comprehensive NGS panel. This is the first study reporting library quality metrics according to the TSO500 analysis pipeline.

Caresses, whispers and affective faces: A theoretical framework for a multimodal interoceptive mechanism underlying ASMR and affective touch: An evolutionary and developmental perspective for understanding ASMR and affective touch as complementary processes within affiliative interactions.

Autonomous sensory meridian response (ASMR) and affective touch (AT) are two phenomena that have been independently investigated from separate lines of research. In this article, I provide a unified theoretical framework for understanding and studying them as complementary processes. I highlight their shared biological basis and positive effects on emotional and psychophysiological regulation. Drawing from evolutionary and developmental theories, I propose that ASMR results from the development of biological mechanisms associated with early affiliative behaviour and self-regulation, similar to AT. I also propose a multimodal interoceptive mechanism underlying both phenomena, suggesting that different sensory systems could specifically respond to affective stimulation (caresses, whispers and affective faces), where the integration of those inputs occurs in the brain's interoceptive hubs, allowing physiological regulation. The implications of this proposal are discussed with a view to future research that jointly examines ASMR and AT, and their potential impact on improving emotional well-being and mental health.

Microbiota and Diapause-Induced Neuroprotection Share a Dependency on Calcium But Differ in Their Effects on Mitochondrial Morphology.

The balance between the degeneration and regeneration of damaged neurons depends on intrinsic and environmental variables. In nematodes, neuronal degeneration can be reversed by intestinal GABA and lactate-producing bacteria, or by hibernation driven by food deprivation. However, it is not known whether these neuroprotective interventions share common pathways to drive regenerative outcomes. Using a well established neuronal degeneration model in the touch circuit of the bacterivore nematode Caenorhabditis elegans, we investigate the mechanistic commonalities between neuroprotection offered by the gut microbiota and hunger-induced diapause. Using transcriptomics approaches coupled to reverse genetics, we identify genes that are necessary for neuroprotection conferred by the microbiota. Some of these genes establish links between the microbiota and calcium homeostasis, diapause entry, and neuronal function and development. We find that extracellular calcium as well as mitochondrial MCU-1 and reticular SCA-1 calcium transporters are needed for neuroprotection by bacteria and by diapause entry. While the benefits exerted by neuroprotective bacteria require mitochondrial function, the diet itself does not affect mitochondrial size. In contrast, diapause increases both the number and length of mitochondria. These results suggest that metabolically induced neuronal protection may occur via multiple mechanisms.

SUMMARY: The use of new technological resources in the teaching of anatomy has promoted the need to adapt the educational model, making it more student-centered, dynamic, and participatory through digital and 3D tools, directing the knowledge towards its clinical application, but under a curricular adjustment that tends to take fewer contact hours in the classroom or laboratory. This work describes the local experience of a new School of Medicine in Chile, reported in 2018, and other work from training centers presented at the "SECTRA Users Meeting 2019 Stockholm", Karolinska Institutet, Sweden. This work describes the oral reports on the application of new digital resources such as; the SECTRA® digital tactile dissection table and Erler- Zimmer® 3D printed cadaveric anatomical models, databases on digital anatomy, in addition, its impact on academic performance, reported by users from different countries, such as Australia, Canada, Chile, China, Colombia, United States of America (USA) and Sweden. The data was collected and analyzed from the information reported in the oral presentations and summaries delivered by the speakers.The vast majority of the exhibiting countries declared the combined use of digital and 3D resources added to the traditional ones for teaching anatomy. Only the representative from the USA stated that they exclusively used digital resources (in the laboratory and online), an experience corresponding to a young and innovative medical school. Most of the educational centers stated that they used the digital dissection table in a large proportion of their curricular contents, in association with RIS/PACS-type platforms such as the IDS7 SECTRA portal or those used by the training center. The use of new digital and 3D technologies has gained an important space in the anatomy teaching curriculum, complementing the use of traditional resources.

Exame físico em ginecologia / Physical examination in gynecology

O exame físico na prática ginecológica diuturna é o sustentáculo de uma perspectiva diagnóstica com vistas a uma abordagem individualizada, oportuna e humanizada da paciente. Lança mão de técnica semiótica clássica, inicialmente, após avaliação de sinais vitais, minuciosa inspeção ectoscópica, seguida de exame físico especial. E deverá ser realizado em ambiente adequadíssimo, sem nenhuma improvisação e ou adaptações não compatíveis, com a importância e a segurança garantidas por um exame físico de boa qualidade. O exame físico de mamas tem como objetivo primordial a identificação de nódulos mamários e, eventualmente, de tumores localmente avançados; e relativa tranquilidade é assegurada às pacientes quando ele é considerado normal. O exame físico vulvar permite a identificação de prolapso de órgãos pélvicos, neoplasia intraepitelial e/ou invasiva vulvar e distúrbios de desenvolvimento sexual, além de oferecer subsídios para a propedêutica da vulvodínea, sendo, principalmente, uma oportunidade para o diagnóstico em dermatologia vulvar, mesmo a vulva correspondendo a apenas 1% da pele feminina. O exame especular, um clássico da ginecologia, é indispensável para a triagem do câncer de colo uterino. Por fim, o toque genital, a despeito de sua subjetividade, permite a avaliação dos órgãos genitais internos.

Physical examination in daytime gynecological practice is the mainstay of a diagnostic perspective with a view to an individualized, timely and humanized approach to the patient; resorting to the classical semiotic technique, initially, after assessing vital signs, a thorough ectoscopic inspection, followed by a special physical examination; which should be carried out in a very suitable environment, without any improvisation or adaptations that are not compatible with the importance and safety guaranteed by a good quality physical examination. The primary objective of the physical examination of the breasts is to identify breast nodules and possibly locally advanced tumors; in addition to relative tranquility, assured to patients, when the respective exam is considered normal. Vulvar physical examination allows the identification of pelvic organ prolapse; vulvar intraepithelial and/or invasive neoplasia; sexual development disorders; in addition to offering subsidies for the propaedeutics of vulvodynia; and, above all, it is an opportunity for diagnosis in vulvar dermatology, even though the vulva accounts for only 1% of female skin. Specular examination, a classic in gynecology, is essential for screening for cervical cancer. Finally, the genital touch which, despite its subjectivity, allows the evaluation of the internal genital organs.

Pactolo Bar: An Approach to Mitigate the Midas Touch Problem in Non-Conventional Interaction.

New ways of interacting with computers is driving research, which is motivated mainly by the different types of user profiles. Referred to as non-conventional interactions, these are found with the use of hands, voice, head, mouth, and feet, etc. and these interactions occur in scenarios where the use of mouse and keyboard would be difficult. A constant challenge in the adoption of new forms of interaction, based on the movement of pointers and the selection of interface components, is the Midas Touch (MT) problem, defined as the involuntary action of selection by the user when interacting with the computer system, causing unwanted actions and harming the user experience during the usage process. Thus, this article aims to mitigate the TM problem in interaction with web pages using a solution centered on the Head Tracking (HT) technique. For this purpose, a component in the form of a Bar was developed and inserted on the left side of the web page, called the Pactolo Bar (PB), in order to enable or disable the clicking event during the interaction process. As a way of analyzing the effectiveness of PB in relation to TM, two stages of tests were carried out based on the collaboration of voluntary participants. The first step aims to find the data that would lead to the best configuration of the BP, while the second step aims to carry out a comparative analysis between the PB solution and the eViacam software, whose use is also focused on the HT technique. The results obtained from the use of PB were considered promising, since the analysis of quantitative data points to a significant prevention of involuntary clicks in the iteration interface and the analysis of qualitative data showed the development of a better user experience due to the ease of use, which can be noticed in elements such as the PB size, the triggering mechanism, and its positioning in the graphical interface. This study benefits in the context of the user experience, because, when using non-conventional interactions, basic items such as aspects of the graphic elements, and interaction events raise new studies that seek to mitigate the problem of the Midas Touch.

Gentle Touch and Sucrose for Pain Relief during Suctioning in Preterm Newborns-A Randomized Clinical Trial.

Pain management is challenging in neonatal care. We aimed to compare the effects of gentle touch and sucrose on pain relief during suctioning in premature newborns (PTNB). This crossover randomized clinical trial enrolled PTNBs with low birth weight, hemodynamically stable, and requiring suctioning during hospitalization in the neonatal intensive care unit. PTNBs underwent three different suctioning procedures. The first was performed without intervention (baseline). Right after, PTNBs were randomly allocated (sucrose and gentle touch or vice versa) to the next two suctioning procedures. Two validated scales assessed pain: the Neonatal Infant Pain Scale (NIPS) and the Premature Infant Pain Profile-Revised (PIPP-R). We evaluated 50 PTNBs (mean of 28 weeks) with a mean low birth weight of 1050 g; most were under continuous positive airway pressure 37 (74%) and mechanical ventilation 41 (82%). Gentle touch was efficacious for pain relief since NIPS (p = 0.010) compared to baseline. Sucrose was also effective in reducing pain NIPS and PIPP-R (p < 0.001). Although the two interventions reduced pain, no difference was observed between gentle touch and sucrose.

Universality without uniformity - infants' reactions to unresponsive partners in urban Germany and rural Ecuador.

Previous studies based on non-WEIRD (Western, Educated, Industrialized, Rich, and Democratic) samples provide initial evidence that the still-face effect is universal. Based on the assumption that - independent of their cultural niches - infants share some fundamental expectations of social interactions, we put forth the assumption that a universal response exists for when a social interaction is interrupted. At the same time, we hypothesized that the size of the effect depends on the typicality of the interaction that precedes the adult partners' interruption. To test these hypotheses, we conducted the Still-Face Paradigm (SFP) with infants (3- and 4.5-month-olds) from two cultural milieus, namely Münster (urban Germany) and the Kichwa ethnic group from the northern Andes region (rural Ecuador), as these contexts presumably offer different ways of construing the self that are associated with different parenting styles, namely distal and proximal parenting. Furthermore, we developed a paradigm that comes much closer to the average expected environment of Kichwa infants, the "No-Touch Paradigm" (NTP). Overall, the results support our initial hypothesis that the still-face effect is universal. Moreover, infants from both cultural milieus responded to the no-touch condition with a change in negative affect. At the same time, some of the infants' responses were accentuated in a culture-specific way: Kichwa infants had a stronger response to an interruption of proximal interaction patterns during the NTP. While our findings underline infants' universal predisposition for face-to-face interaction, they also suggest that cultural differences in internalized interactions do influence infant behavior and experience and, in turn, development.

Morphological Changes in Endothelial Cell Organelles in a No-Touch Saphenous Vein Graft.

INTRODUCTION: Improved long-term patency of the no-touch (NT) saphenous vein graft has been reported to result from the preservation of a healthy vascular microstructure, especially endothelial cells. However, the precise morphology of endothelial cells and their organelles in NT saphenous vein graft has not been fully investigated. In this study, we assessed the ultrastructure of preserved endothelial cells in saphenous vein graft using transmission electron microscopy. METHODS: Intact control (IC) vein, NT saphenous vein graft, and conventional (CT) saphenous vein graft were harvested from a patient. After observation by light microscopy, the nuclei and mitochondria in the preserved endothelial cells were compared among IC, NT, and CT using transmission electron microscopy, and the endothelial organelles were assessed quantitatively. RESULTS: Light microscopy showed that the preservation of endothelial cells was comparable in IC, NT, and CT. Subsequent transmission electron microscopy observation showed that the nuclei in preserved endothelial cells appeared more swollen in CT than that in NT. Quantitative analysis revealed that nuclear size and circularity of preserved endothelial cells in NT and IC were similar, but those in CT were larger and higher, respectively, than those in IC and NT. In addition, the mitochondrial size in preserved endothelial cells in CT was larger than that in IC and NT. CONCLUSION: Necrotic changes in endothelial organelles characterized by swelling of nuclei and mitochondria were prominent in CT saphenous vein graft. The normally maintained ultrastructure of preserved endothelial cells in NT saphenous vein graft could contribute to long-term patency.

Decreased self-reported receiving of social touch and social support predict loneliness in healthy adults.

Loneliness has emerged as a public health concern. Previous research has reported its deleterious effects on physical and mental health; however, some specific psychophysiological mechanisms in healthy adults remain to be elucidated. The aim of the current study is to investigate whether self-reported social support and social touch (giving and receiving social touch), as well as resting heart rate variability (HRV), are significant negative predictors of loneliness in healthy adults. The study sample consists of 120 healthy students (50% female) with a mean age of 21.85 years old (DP= 2.21). The students were asked to complete a psychiatric screening questionnaire utilizing loneliness, social support, and social touch scales. HRV was derived from an electrocardiographic signal recorded for 15 min, with the participant relaxed in a supine position. Linear regression analyses were conducted to evaluate loneliness as a function of social support, social touch (giving or receiving touch), and resting HRV. The results show that social support (p< 0.001) and social touch, specifically receiving touch (p< 0.002), accounted for a significant proportion of the variance in loneliness. However, neither giving touch nor resting HRV was a significant predictor of loneliness. The current study highlights specific psychosocial factors in healthy adults that should be considered as promising pathways in order to reduce or work toward preventing loneliness, thus promoting better health and well-being.

Materials and methods: This is a quasi-experimental study, with a sample of 13 PTNB who underwent therapeutic touch for 15 minutes in 2 daily sessions (6 am and 8 pm), with pre- and post-assessment of NOC "Preterm Infant Organization." Descriptive analysis was performed. Results: The participants were allocated to the control group and the intervention group in a similar way. Pre- and post-intervention changes were observed, but especially in the hand posture indicator, with a difference between both groups of 0.74 with a p-value of 0.006. Conclusions: The practice of therapeutic touch with RNPT receiving nasal CPAP allows for improving the comfort of the RNPT through physiological and neurobehavioral indicators.

Introdução: O recém-nascido prematuro apresenta uma imaturidade do sistema cardiorrespiratório, o que dificulta a adaptação ao ambiente extrauterino e leva a múltiplas complicações que requerem intervenções que melhorem a ventilação e as trocas gasosas como a oxigenação por meio de dispositivos de suporte terapêutico, como via aérea positiva contínua pressão ou CPAP. Objetivo: determinar o efeito do toque terapêutico na adaptação do recém-nascido pré-termo com CPAP. Materiais e métodos: Estudo quase experimental, com uma amostra de 13 PTNIs a quem foi aplicado o toque terapêutico durante 15 minutos, com 2 sessões diárias (6h e 20h), com avaliação antes e após CRE: "Adaptação do prematuro". Ao qual foi realizada a análise descritiva correspondente. Resultados: Todos os participantes foram alocados no grupo controle e no grupo intervenção de forma semelhante, apresentando alterações antes e após a intervenção, mas principalmente no indicador de postura das mãos, com diferença entre os dois grupos foi de 0,74 com um valor de p 0,006. Conclusões: A aplicação do toque terapêutico ao RNPT com CPAP nasal permite melhorar o conforto do RNPT através de indicadores fisiológicos e neurocomportamentais.

Ferenczian Elasticity in the Analysis of an Adolescent.

Psychoanalytic work with adolescents poses a challenge for analysts who adhere to standard analytic technique as many adolescents who need analytic intervention resist such a structured approach to analysis. The author finds that elasticity of technique is currently widely used by analysts when working with this difficult age group even though they may be unaware that this is, in fact, a Ferenczian technique. Clinical examples are presented to illustrate how frequently the technique is used in cases of resistant, troubled youth. The author outlines an approach that is sensitive to these resistances and makes compromises in technique based on the principle that engaging a troubled youth in a therapeutic venture is preferable to refusing treatment based on the patient's not being able to adhere to standard analytic technique. In this sense, Ferenczi was an early herald of the type of contemporary analytic work that is practiced currently especially with a difficult population of patients.

Understanding the impact of newborn touch upon mothers of hospitalized preterm neonates

Introduction: Many interventions have been designed to support the development of the preterm baby and minimise the complications of prematurity. However, there is limited evidence of the possible psychological benefits of touch to the mother when she is the one performing the support programme during the hospitalisation of her newborn. Objective: This study explored whether the type of touch provided to preterm neonates had an impact on maternal self-efficacy, self-esteem and maternal-to-infant attachment, as-well-as newborn weight gain. Methods: Using a randomised cluster trial, forty babies and their mothers were allocated to one of two groups receiving either a touch-based intervention (TAC-TIC; Touching And Caressing; Tender In Caring) or spontaneous touch. Results: Mothers who provided the touch-based intervention demonstrated greater increases in self-efficacy, self-esteem and attachment, and babies gained more weight than those using spontaneous touch. Conclusion: The results indicate that systematic touch interventions may be used to facilitate the mother-baby relationship as well as to promote newborn weight gain.

Introdução: muitas intervenções têm sido desenhadas para apoiar o desenvolvimento do bebê prematuro e minimizar as complicações da prematuridade. No entanto, são limitadas as evidências dos possíveis benefícios psicológicos do toque para a mãe quando é ela quem realiza o programa de apoio durante a hospitalização de seu recém-nascido.Objetivo: este estudo explorou se o tipo de toque fornecido aos recém-nascidos prematuros teve impacto na autoeficácia materna, autoestima e apego materno-infantil, bem como no ganho de peso do recém-nascido.Método: usando um estudo randomizado de cluster, quarenta bebês e suas mães foram alocados em um dos dois grupos que receberam uma intervenção baseada em toque (TAC-TIC; Tocando e acariciando; Tender In Caring) ou toque espontâneo.Resultados: as mães que forneceram a intervenção baseada no toque demonstraram maiores aumentos na autoeficácia, autoestima e apego, e os bebês ganharam mais peso do que aqueles que usaram o toque espontâneo.Conclusão: os resultados indicam que intervenções sistemáticas de toque podem ser utilizadas para facilitar a relação mãe-bebê, bem como para promover o ganho de peso do recém-nascido.

Visuo-Motor Affective Interplay: Bonding Scenes Promote Implicit Motor Pre-dispositions Associated With Social Grooming-A Pilot Study.

Proximity and interpersonal contact are prominent components of social connection. Giving affective touch to others is fundamental for human bonding. This brief report presents preliminary results from a pilot study. It explores if exposure to bonding scenes impacts the activity of specific muscles related to physical interaction. Fingers flexion is a very important component when performing most actions of affectionate contact. We explored the visuo-motor affective interplay by priming participants with bonding scenes and assessing the electromyographic activity of the fingers flexor muscle, in the absence of any overt movements. Photographs of dyads in social interaction and of the same dyads not interacting were employed. We examined the effects upon the electromyographical activity: (i) during the passive exposure to pictures, and (ii) during picture offset and when expecting the signal to perform a fingers flexion task. Interacting dyads compared to matched non-interacting dyads increased electromyographic activity of the fingers flexor muscle in both contexts. Specific capture of visual bonding cues at the level of visual cortex had been described in the literature. Here we showed that the neural processing of visual bonding cues reaches the fingers flexor muscle. Besides, previous visualization of bonding cues enhanced background electromyographic activity during motor preparation to perform the fingers flexion task, which might reflect a sustained leakage of central motor activity downstream leading to increase in firing of the respective motor neurons. These data suggest, at the effector level, an implicit visuo-motor connection in which social interaction cues evoke intrinsic dispositions toward affectionate social behavior.
