Identification of surgically-induced longitudinal lesions of the equine deep digital flexor tendon in the digital flexor tendon sheath using contrast-enhanced ultrasonography: an ex-vivo pilot study

BACKGROUND: Longitudinal tears in the lateral aspect of the deep digital flexor tendon are the most common causes of pain localised to the equine digital flexor tendon sheath. However conventional ultrasonographic techniques provide limited information about acute lesions. Ultrasonographic contrast agents are newly developed materials that have contributed to advancement in human diagnostic imaging. They are currently approved for intravenous use in human and animal models. In this study we described intrathecal use in the horse. This study was undertaken to evaluate the reliability of standard and angle contrast-enhanced ultrasonography to detect and characterize surgically-induced longitudinal lesions in the deep digital flexor tendons. In this pilot study surgically-induced lesions were created in the lateral aspect of the deep digital flexor tendon within the digital flexor tendon sheath in 10 isolated equine limbs to generate a replicable model for naturally occurring lesions. Another 10 specimens were sham operated. All the limbs were examined ultrasonographically before and shortly after the intrasynovial injection of an ultrasound contrast agent containing stabilised microbubbles. The images were blindly evaluated to detect the ability to identify surgically-created lesions. The deep digital flexor tendons were dissected and a series of slices were obtained. The depth of longitudinal defects identified with contrast-enhanced ultrasound scans was compared to the real extent of the lesions measured in the corresponding gross tendon sections. RESULTS: Contrast-enhanced ultrasonography with both angle and standard approach provided a significant higher proportion of correct diagnoses compared to standard and angle contrast ultrasonography (p < 0.01). Contrast-enhanced ultrasonography reliably estimated the depth of surgically-induced longitudinal lesions in the deep digital flexor tendons. CONCLUSION: Contrast-enhanced ultrasound of the digital flexor tendon sheath could be an effective tool to detect intrasynovial longitudinal tears of the deep digital flexor tendon, although an in vivo study is required to confirm these results for naturally occurring lesions

STUDY ON THE CORRELATION BETWEEN SELF-ESTEEM, COPING AND CLINICAL SYMPTOMS IN A GROUP OF YOUNG ADULTS: A BRIEF REPORT

The aim of this research is to analyze how the experiences and representations of self-esteem correlate with clinical symptoms, as well as specific non-functional coping strategies in order to overcome difficulties in the development of autonomy and decision-making.Data show that the coping resources of individuals are directed more towards the Self than towards the social, sometimes even in terms of preoccupation with the Self and social isolation. Low self-esteem has correlations with somatization. It is especially in the female gender and is related to an image of Self that is not positive

Objects as Communicative Mediators in Children With Autism Spectrum Disorder

In recent years, the socio-material perspective has informed an important interdisciplinary debate concerning the role of the physical world (i.e., the objects) in human psychological development. Several studies in the field of developmental psychology showed positive achievements in explaining the relationship between the subject and the social context through a socio-material approach, in particular in the early development. The importance of objects was also recognized in children with autism spectrum disorder (ASD), showing that these children are characterized by alterations in the use of the objects from early development. Some studies highlighted that objects could be a facilitator in the interactions between children with ASD and peers. However, the role of objects was not sufficiently investigated in interactions between children with ASD and adults. The main purpose of the present study was to investigate in children with ASD the communicative function that the activities with objects assume in the interactions with adults, highlighting the mediator role of objects in these interactions. More generally, this study also aims to highlight the relevance of adopting a socio-material perspective to explore some neglected aspects of the psychological activity of children with ASD. To test this hypothesis, we conducted an extensive exploratory study, collecting data from a sample of 3-year-old (N = 18; F = 3) and 4-year-old (N = 26; F = 3) with ASD. Children were observed in a free-play situation with an adult. They were free to choose an object from a predefined set. Through quantitative data, we have described the general characteristics of the manipulation of objects; through qualitative data, we aimed to capture and describe, in microgenetic sequences, some characteristics of children\u2019s activities, defined as socio-material. The analysis of the socio-material activities suggested the role of objects as mediator of the interactions between children with ASD and adults

Editorial: Sociomateriality in Children With Typical and/or Atypical Development.

L'idea di sociomaterialità ha origine principalmente dalla vasta area di prospettive sullo sviluppo psicologico legate all'empirismo. In termini semplici, si potrebbe dire che la sociomaterialità sottolinea il contributo dell'esperienza individuale e collettiva ponendo maggiormente l'accento sul ruolo che la corporeità, i contesti fisici e gli oggetti giocano nello sviluppo o nell'emergere di funzioni psicologiche. Purtroppo, come ogni semplificazione, anche questa ha dei limiti oggettivi. Ciò che rende difficile stabilire un quadro unificato per definire la sociomaterialità, e soprattutto per determinare la sua relazione con lo sviluppo psicologico, è prima di tutto una questione epistemologica che è ancora oggetto di un ampio dibattito in diverse aree scientifiche, tra cui la filosofia (Searle, 2007) archeologia e culture materiali (Malafouris, 2013), ergonomia (Geslin, 2017), antropologia e sociologia (Latour, 2005), scienze cognitive (Clark, 2008), psicoterapia (Searles, 1960), psicologia dello sviluppo (Iannaccone et al. 2018; Moro e Rodríguez, 1998; Moro, 2016) e l'apprendimento stesso (Engeström, 2015; Iannaccone, 2017; Cattaruzza et al., 2019). Nella misura limitata di questa introduzione al variegato Topic ospitato da Frontiers in Psychology, possiamo identificare il cuore del problema epistemologico in due domande fondamentali: (a) quali sono i confini della mente rispetto alla corporeità e al contesto in cui opera? e (b) quale potrebbe essere il contributo reale che gli artefatti danno allo sviluppo delle funzioni psicologiche, in particolare l'apprendimento?The idea of sociomateriality mainly originates from the vast area of perspectives on psychological development related to empiricism. In simple terms, it could be said that sociomateriality stresses the contribution of individual and collective experience by putting more emphasis on the role that corporeity, physical contexts, and objects play in the development or emergence of psychological functions. Unfortunately, like any simplification, this one has objective limits. What makes it difficult to establish a unified framework to define sociomateriality, and above all to determine its relationship to psychological development, is, first of all, an epistemological question that is still the subject of a wide debate in several scientific areas, including philosophy (Searle, 2007) archaeology and material cultures (Malafouris, 2013), ergonomics (Geslin, 2017), anthropology and sociology (Latour, 2005), cognitive sciences (Clark, 2008), psychotherapy (Searles, 1960), developmental psychology (Iannaccone et al. 2018; Moro and Rodríguez, 1998; Moro, 2016) and learning itself (Engeström, 2015; Iannaccone, 2017; Cattaruzza et al., 2019). Within the limited extent of this introduction to the variegated Topic hosted by Frontiers in Psychology, we can identify the heart of the epistemological problem in two fundamental questions: (a) what are the boundaries of the mind with respect to corporeity and the context in which it operates? and (b) what could be the real contribution that artefacts give to the development of psychological functions, particularly learning

Tutoramento entre pares e integração universitária da deficiência

O estudo analisa a relação entre tutor e tutorado com deficiências no contexto universitário. A hipótese de pesquisa é que o método do tutoramento entre pares poderá facilitar a integração dos estudantes universitários com deficiências e que a compartilha dos problemas e as paritárias condições de partida do tutor e do tutorado ajude os mútuos processos de socialização. Vinte tutores preencheram um questionário elaborado ad hoc, e o corpus narrativo foi submetido a uma análise textual. Os resultados evidenciam o fato do peer tutoring ser uma metodologia idônea para o desenvolvimento de uma mútua relação de competências, no âmbito de uma relação afetiva e simétrica; isso permite ultrapassar a perspetiva assistencial relativa à deficiência, incita o tutorado a “ultrapassar a si próprio”, facilitando a sua aprendizagem e assim ativando a sua “zona de desenvolvimento proximal”

Physiological pregnancy in a tiger affected by endometritis and benign mesenchymal neoplasm.

In large felids, uncomplicated endometritis and benign mesenchymal uterine tumours usually represent post-mortem findings. These pathologies generally remain clinically asymptomatic, and their impact on reproductive outcome and maternal care is unknown. A 13-year-old female tiger (Panthera tigris) was evaluated by a team of veterinarians from the University of Padova for abnormal behaviour after parturition. The animal spontaneously gave birth to a healthy male cub of 1.460 kg, but after three hours of normal parental care, she showed careless about the cub, occasional abdominal contractions, excessive self-licking and restlessness. After 10 hours of continuous observation, the tiger was anaesthetised for a complete clinical evaluation. The physical examination was unremarkable, but a vaginal bloody/mucous discharge with no obstruction of the birth canal was noted. Abdominal ultrasound revealed an enlarged left uterine horn with heterogeneous echogenicity. Blood analysis showed moderate neutrophilia and leucocytosis. Differential diagnoses included placental retention, uterine inflammation/infection, neoplasia. The tiger was transferred to the Veterinary Teaching Hospital where the explorative laparotomy and the ovario-hysterectomy were performed. The uterine horns appeared asymmetric and two nodular lesions of 1.5-cm-diameter were observed on the left horn. Histological assessment indicated the presence of a multifocal, subacute, moderate neutrophilic endometritis in both horns associated with diffuse, severe oedema. The nodules were consistent with a mesenchymal benign neoplasia. No relevant complication was observed in the following postoperative period and the cub was successfully hand raised. To the best of our knowledge, no report describes the birth of a healthy cub from a tiger affected by endometritis and neoplasia. Considering the normal maternal care observed in the previous twin-pregnancies in this animal, we cannot exclude that the uterine affection caused her abnormal behaviour in this case. Therefore, careful observation of the mother in the post-partum period is always strongly recommended

perceived social support and clinical symptomatology in italian university students

Social support can influence the perceptions of individual and social well-being for university students. We sought to verify whether the perceptions of social support correlate with the manifestation of clinical symptoms in young university students. A total of 26 participants, 58% female and 42% male, between the ages of 19 and 27 were included. The following tests were administered: SCL-90-R – scale for the self-evaluation of general psychopathology and MSPSS – self-assessment scale for the perception of social support. The students who perceived low levels of social support had high levels of clinical symptomatology (especially for internalised disorders). The index for a high intensity of symptoms Positive Symptom Total is correlated with a low level of perceived social support. Keywords: Clinical symptomatology, perceived social support, university students

Mapping and assessment of ecosystems and their services. Urban ecosystems

Action 5 of the EU Biodiversity Strategy to 2020 requires member states to Map and Assess the state of Ecosystems and their Services (MAES). This report provides guidance for mapping and assessment of urban ecosystems. The MAES urban pilot is a collaboration between the European Commission, the European Environment Agency, volunteering Member States and cities, and stakeholders. Its ultimate goal is to deliver a knowledge base for policy and management of urban ecosystems by analysing urban green infrastructure, condition of urban ecosystems and ecosystem services. This report presents guidance for mapping urban ecosystems and includes an indicator framework to assess the condition of urban ecosystems and urban ecosystem services. The scientific framework of mapping and assessment is designed to support in particular urban planning policy and policy on green infrastructure at urban, metropolitan and regional scales. The results are based on the following different sources of information: a literature survey of 54 scientific articles, an online-survey (on urban ecosystems, related policies and planning instruments and with participation of 42 cities), ten case studies (Portugal: Cascais, Oeiras, Lisbon; Italy: Padua, Trento, Rome; The Netherlands: Utrecht; Poland: Poznań; Spain: Barcelona; Norway: Oslo), and a two-day expert workshop. The case studies constituted the core of the MAES urban pilot. They provided real examples and applications of how mapping and assessment can be organized to support policy; on top, they provided the necessary expertise to select a set of final indicators for condition and ecosystem services. Urban ecosystems or cities are defined here as socio-ecological systems which are composed of green infrastructure and built infrastructure. Urban green infrastructure (GI) is understood in this report as the multi-functional network of urban green spaces situated within the boundary of the urban ecosystem. Urban green spaces are the structural components of urban GI. This study has shown that there is a large scope for urban ecosystem assessments. Firstly, urban policies increasingly use urban green infrastructure and nature-based solutions in their planning process. Secondly, an increasing amount of data at multiple spatial scales is becoming available to support these policies, to provide a baseline, and to compare or benchmark cities with respect to the extent and management of the urban ecosystem. Concrete examples are given on how to delineate urban ecosystems, how to choose an appropriate spatial scale, and how to map urban ecosystems based on a combination of national or European datasets (including Urban Atlas) and locally collected information (e.g., location of trees). Also examples of typologies for urban green spaces are presented. This report presents an indicator framework which is composed of indicators to assess for urban ecosystem condition and for urban ecosystem services. These are the result of a rigorous selection process and ensure consistent mapping and assessment across Europe. The MAES urban pilot will continue with work on the interface between research and policy. The framework presented in this report needs to be tested and validated across Europe, e.g. on its applicability at city scale, on how far the methodology for measuring ecosystem condition and ecosystem service delivery in urban areas can be used to assess urban green infrastructure and nature-based solutions

Risk factors associated with adverse fetal outcomes in pregnancies affected by Coronavirus disease 2019 (COVID-19): a secondary analysis of the WAPM study on COVID-19.

Objectives To evaluate the strength of association between maternal and pregnancy characteristics and the risk of adverse perinatal outcomes in pregnancies with laboratory confirmed COVID-19. Methods Secondary analysis of a multinational, cohort study on all consecutive pregnant women with laboratory-confirmed COVID-19 from February 1, 2020 to April 30, 2020 from 73 centers from 22 different countries. A confirmed case of COVID-19 was defined as a positive result on real-time reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay of nasal and pharyngeal swab specimens. The primary outcome was a composite adverse fetal outcome, defined as the presence of either abortion (pregnancy loss before 22 weeks of gestations), stillbirth (intrauterine fetal death after 22 weeks of gestation), neonatal death (death of a live-born infant within the first 28 days of life), and perinatal death (either stillbirth or neonatal death). Logistic regression analysis was performed to evaluate parameters independently associated with the primary outcome. Logistic regression was reported as odds ratio (OR) with 95% confidence interval (CI). Results Mean gestational age at diagnosis was 30.6+/-9.5 weeks, with 8.0% of women being diagnosed in the first, 22.2% in the second and 69.8% in the third trimester of pregnancy. There were six miscarriage (2.3%), six intrauterine device (IUD) (2.3) and 5 (2.0%) neonatal deaths, with an overall rate of perinatal death of 4.2% (11/265), thus resulting into 17 cases experiencing and 226 not experiencing composite adverse fetal outcome. Neither stillbirths nor neonatal deaths had congenital anomalies found at antenatal or postnatal evaluation. Furthermore, none of the cases experiencing IUD had signs of impending demise at arterial or venous Doppler. Neonatal deaths were all considered as prematurity-related adverse events. Of the 250 live-born neonates, one (0.4%) was found positive at RT-PCR pharyngeal swabs performed after delivery. The mother was tested positive during the third trimester of pregnancy. The newborn was asymptomatic and had negative RT-PCR test after 14 days of life. At logistic regression analysis, gestational age at diagnosis (OR: 0.85, 95% CI 0.8-0.9 per week increase; pPeer reviewe
