Diagnostics using the change-of-direction and acceleration test (codat) of the biomechanical patterns associated with knee injury in female futsal players: a cross-sectional analytical study

The primary aim of this study was to identify kinematic differences at initial contact between female futsal players with and without previous knee injury, using a functional motor pattern test. The secondary aim was to determine kinematic differences between the dominant and non-dominant limb in the whole group, using the same test. A cross-sectional study was performed in 16 female futsal players allocated into two groups: eight females with a previous knee injury, i.e., affected by the valgus collapse mechanism without surgical intervention, and eight with no previous injury. The evaluation protocol included the change-of-direction and acceleration test (CODAT). One registration was made for each lower limb, i.e., the dominant (the preferred kicking limb) and non-dominant limb. A 3D motion capture system (Qualisys AB, Göteborg, Sweden) was used to analyze the kinematics. The Cohen’s d effect sizes between the groups demonstrated a strong effect size towards more physiological positions in the non-injured group in the following kinematics in the dominant limb: hip adduction (Cohen’s d = 0.82), hip internal rotation (Cohen’s d = 0.88), and ipsilateral pelvis rotation (Cohen’s d = 1.06). The t-test for the dominant and non-dominant limb in the whole group showed the following differences in knee valgus: dominant limb (9.02 7.31 degrees) and non-dominant limb (1.27 9.05 degrees) (p = 0.049). Conclusions: The players with no previous history of knee injury had a more physiological position for avoiding the valgus collapse mechanism in the hip adduction and internal rotation, and in the pelvis rotation in the dominant limb. All the players showed more knee valgus in the dominant limb, which is the limb at greater risk of injury

cmv1 is a gate for Cucumber mosaic virus transport from bundle sheath cells to phloem in melon

Cucumber mosaic virus (CMV) has the broadest host range among plant viruses, causing enormous losses in agriculture. In melon, strains of subgroup II are unable to establish a systemic infection in the near‐isogenic line SC12‐1‐99, which carries the recessive resistance gene cmv1 from the accession PI 161375, cultivar ‘Songwhan Charmi’. Strains of subgroup I overcome cmv1 resistance in a manner dependent on the movement protein. We characterized the resistance conferred by cmv1 and established that CMV‐LS (subgroup II) can move from cell to cell up to the veins in the inoculated leaf, but cannot enter the phloem. Immunogold labelling at transmission electron microscopy level showed that CMV‐LS remains restricted to the bundle sheath (BS) cells in the resistant line, and does not invade vascular parenchyma or intermediary cells, whereas, in the susceptible line ‘Piel de Sapo’ (PS), the virus invades all vein cell types. These observations indicate that the resistant allele of cmv1 restricts systemic infection in a virus strain‐ and cell type‐specific manner by acting as an important gatekeeper for virus progression from BS cells to phloem cells. Graft inoculation experiments showed that CMV‐LS cannot move from the infected PS stock into the resistant cmv1 scion, thus suggesting an additional role for cmv1 related to CMV transport within or exit from the phloem. The characterization of this new form of recessive resistance, based on a restriction of virus systemic movement, opens up the possibility to design alternative approaches for breeding strategies in melon.Fil: Guiu Aragonés, Cèlia.

Un caso de seudología.

Se estudia un caso de seudología fantástica, trastorno de la personalidad incluido en los trastornos no especificados (DSM-III-R) y que podría ser definido, siguiendo a CASTILLA DEL PINO, como una caracterosis impositiva del self intelectual. El síntoma fundamental, en el caso que comentamos, está constituido por la personalidad del paciente, que se cimenta en un un falso self -expresado éste en los numerosos engaños y mentiras que giran, principalmente, alrededor de su identidad intelectual-. Como consecuencia de estas conductas mendaces, el paciente manifiesta, además, conductas desadaptivas (alcoholismo, endeudamientos en cadena, etc). A diferencia del fantasioso, el seudólogo opta por la acción: su intención es imponer el self fantaseado a los demás, por lo que no le basta la simple fantasía si ésta no es llevada a la práctica. Asímismo, es preciso diferenciar el cuadro seudólogo de las neurosis histéricas, estados hipomaníacos y psicosis paranoides crónicas de exaltación intelectual. El abordaje psicoterapéutico suele verse dificultado por la actitud del paciente

A Reliability Generalization Meta-Analysis of the Padua Inventory of Obsessions and Compulsions

AbstractThe Padua Inventory (PI) of obsessions and compulsions is one of the most usually applied tests to assess obsessive-compulsive symptomatology in research contexts as well as for clinical and screening purposes. A reliability generalization meta-analysis was accomplished to estimate the average reliability of the PI scores and to search for characteristics of the samples and studies that can explain the variability among reliability estimates. An exhaustive literature search enabled us to select 39 studies (53 independent samples) that reported alpha and/or test-retest coefficients with the data at hand for the PI total score and subscales. An excellent average coefficient alpha was found for the PI total score (M= .935; 95%CI = .922–.949) and for Impaired Mental Control subscale (M= .911; 95%CI = .897–.924), being good for Contamination (M= .861; 95%CI = .841–.882) and Checking (M= .880; 95%CI = .856–.903), and fair for Urges and Worries (M= .783; 95%CI = .745–.822). The average test-retest reliability for PI total score was also satisfactory (M= .835; 95%CI = .782–.877). Moderator analyses showed larger coefficients alpha for larger standard deviation of the PI total scores (p= .0005;R2= .46), for adapted versions of the test (p= .002;R2= .32), and for samples composed of clinical participants (p= .066;R2= .10). The practical implications of these results are discussed as well as the need for researchers to report reliability estimates with the data at hand.</jats:p

Attitudes toward School Violence against LGBTQIA+. A Qualitative Study

School climate is one of the main concerns in terms of research and intervention worldwide. Although it can be directed toward any student, some groups seem to be more vulnerable, as is the case of the LGBTQIA+ (lesbian, gay, bisexual, transgender, queer and intersex +) students, among others. Attitudes toward violence are a construct of particular importance for action plans focused on improving school coexistence. The aim of this study is to examine attitudes toward school violence against LGBTQIA+ students and their relationship with violent behaviors. For this purpose, 96 Spanish students of Spanish elementary education (PE) and compulsory secondary education (CSE) participated in this qualitative study through focus groups for its subsequent thematic analysis. The results identify four types of attitudes toward violence, such as the use of violence as a form of fun, to feel better, when it is perceived as legitimate, and as a way of relating to the LGBTQIA+ community. In addition, a greater number of negative attitudes and violent behaviors toward homosexual boys and transgender minors are observed

Changes in the Abundance of Monoterpenes from Breathable Air of a Mediterranean Conifer Forest: When Is the Best Time for a Human Healthy Leisure Activity?

The exposure to monoterpenes emitted by plants to the air might provide human health benefits during forest-based leisure activities. However, forests, especially Mediterranean ones, lack studies to relate forest production and the emission of monoterpenes, considering potential human forest exposure. Thus, the aim of this study was to analyze the variation in the abundance of monoterpenes in the human breathable air under the canopy of a Mediterranean conifer forest, evaluating the influence of different factors. For this purpose, from March to November 2018, we monitored the abundance of monoterpenes in the air at nose height, leaf development, air temperature and soil water potential in a mountain Mediterranean forest of Pinus pinaster located in Sierra de Albarracín (Teruel, Spain). We detected six monoterpenes, with a-pinene, ß-pinene and limonene being the three most abundant. Temperature was the main environmental factor driving the abundance of monoterpenes in air, with a maxima of abundance found during summer. Leaf development in spring decreased the abundance, while after a drought period, the abundance increased. Thus, people enjoying forest-based activities in Mediterranean conifer areas would be more exposed to air monoterpenes when the temperature increases during the period after leaf development, as long as the trees are not severely water-stressed. If that is the case, the abundance of monoterpenes in the air would increase after the drought period. © 2022 by the authors. Licensee MDPI, Basel, Switzerland
