RESUMO

Background: Women's football has been booming for a few years now, which has led to an increase in the expectation of the players' performance, leading to a more detailed study of women's physiology in the field of sports. Objectives: To analyze the scientific evidence on the influence of menstruation on the performance of female footballers, as well as to analyze the methodological quality of the studies included in this review. Materials and methods: The possible hormonal effects of the menstrual cycle phases on the performance of female footballers were analyzed. The databases used to conduct the searches were Pubmed, Scopus, Virtual Health Library, Web of Science, EBSCO and the Cochrane Library. All included studies met the inclusion criteria. The Cochrane risk of bias tool was used. This systematic review protocol was registered at the International Prospective Register of Systematic Reviews (PROSPERO: CRD42023390652). Results: A total of nine clinical trials were included in this review. A low quality of evidence was observed in the studies. Not all the results support the idea that the menstrual cycle phases can alter the performance of female footballers. Conclusion: This systematic review shows that there is a great deal of controversy about the influence of the menstrual cycle phases on the performance of female footballers. Studies are focused on solely biological factors and gender is normally no part of those studies. Further research with larger samples, and taking not only biological but also sociological factors, are necessary to determine the effects of menstruation on the performance of female footballers.

RESUMO

BACKGROUND: Experiential avoidance (EA) is a psychological mechanism associated with several mental health disorders and is regarded as a relevant target by third-generation cognitive behavioral therapies. It has been mainly assessed through self-report questionnaires, and the AAQ-II is the most used tool. Its psychometric evidence has been mostly tested through the classical test theory (CTT) and very scarcely assessed through Item Response Theory (IRT). METHODS: We used the Graded Response Model to examine its psychometric properties in Spanish-speaking university students (n = 1503; women = 995 (66.2%), mean age = 19.29, SD = 2.45). We tested whether the empirical data fit the model's predictions and estimated the dispersion of persons and items along the experiential avoidance continuum. Moreover, we examined category probability curves to identify the response probability of each answer. Likewise, an item-person map was made where the measurement of persons and items, both on the same scale and along the experiential avoidance continuum, could be observed jointly. Finally, we tested the gender invariance of the scale. RESULTS: We found that the values of the individuals and the items were in the established range to be considered an adequate measure of EA. Additionally, we observed high discrimination indices for all items. The current version with seven answer options could not be optimal and should be tested in future studies. Finally, we found evidence of differential functioning by gender in one of the seven items of the instrument. CONCLUSIONS: Our results indicate that the AAQ-II is a suitable tool for measuring EA and accurately classifying and differentiating EA levels in university students.

RESUMO

BACKGROUND: The prevalence of depression and anxiety has increased in recent years, with many individuals having trouble accessing mental health support. Smartphones have become an integral part of modern life, with apps offering new ways to deliver evidence-based self-help strategies to cope with common mental health symptoms. However, most of them do not have empirical evidence of their overall effectiveness or the effectiveness of their components, which could pose a risk for users. OBJECTIVE: The aim of this study is to evaluate the effectiveness of the modules of evaluation, psychoeducation, and emotional regulation strategies in a multiplatform self-help mental health mobile app in the Maule region of Chile. METHODS: A sample of 196 adults will be selected, who will be randomly assigned to different components of the app for a fixed period to assess its ability to reduce symptomatology. RESULTS: The trial is not yet recruiting and is expected to end in October 2024. The first results are expected in April 2024. CONCLUSIONS: This is the first study in Chile to develop and test the effectiveness of a mobile app to manage anxiety and depression symptoms in adults. The intervention proposed is based on evidence suggesting that the internet or remote intervention tools and self-management of prevalent symptomatology could be the future of mental health care systems in the digital era. If the effects of the intervention are positive, wide implementation in Chile and other Spanish-speaking countries could be possible in the future.

RESUMO

BACKGROUND: ICD-11 Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD) are stress-related disorders. The International Trauma Questionnaire (ITQ) is a widely used instrument to assess PTSD and CPTSD. To date, there is no evidence of the psychometric characteristics of the ITQ in Latin American countries. OBJECTIVE: The aim of this study was to assess the construct and concurrent validity of the Latin American Spanish adaptation of the ITQ in a sample of Chilean adults. METHODS: A sample of 275 Chilean young adults completed the ITQ, a traumatic life events checklist, the Adverse Childhood Experiences Questionnaire, the Depression Anxiety Stress Scales-21, and the Columbia-Suicide Severity Rating Scale short version. Four alternative confirmatory factor analysis models were tested. Correlation analyses were performed to determine concurrent validity with associated measures (number of reported traumatic events, number of adverse childhood experiences, anxiety, depression, and suicidal risk). RESULTS: The second-order two-factor (PTSD and DSO) and the correlated first-order six-factor model provided acceptable fit; however, the first model showed a better fit based on the BIC difference. The PTSD and DSO dimensions, as well as the six ITQ clusters showed positive correlations with reported number of traumatic life-events, reported number of adverse childhood experiences, levels of anxiety, depression, and suicidal risk. CONCLUSIONS: The ITQ Latin American Spanish adaptation provides acceptable psychometric evidence to assess PTSD and CPTSD in accordance with the ICD-11.


This study is an initial validation of the Latin American Spanish adaptation of the ITQ with a Chilean young adults sample.The latent structure of the Latin American Spanish ITQ was better supported by a two-factor second-order model (PTSD/DSO); a six-factor correlated model was also acceptable.The six ITQ symptom clusters, as well as the PTSD/CPTSD dimensions were significantly positively correlated with three criterion variables: anxiety, depression, and suicidal risk.The number of potentially traumatic experiences, as well as number of exposure to adverse childhood experiences, was significantly associated with PTSD/CPTSD symptoms.

RESUMO

The work developed presents, for the first time, a tool to analyze all the thermodynamic models used in the study and development of Stirling engines: isothermal, ideal adiabatic and adiabatic with losses, combined adiabatic thermodynamic with finite speed (CAFS), thermodynamic with finite speed (FST), ideal polytropic and polytropic with losses (PSVL), allowing a comparative study of them. This software (ASCE-UMA), designed and implemented in a Matlab GUI® allows to obtain the operating parameters of these engines, calculating the thermodynamic parameters, power output and efficiency. Additionally, the thermodynamic models can be evaluated with different mechanical configurations, for which different drive mechanisms are implemented: Sinusoidal, Alfa Ross yoke types, Alfa Ross V yoke, Beta rhombic type and free piston Stirling engine (FPSE). Thermoacoustic and other, models could be analyzed by virtue of their similarity of movement with some of the implemented models. In the same way, ASCE-UMA allows the study of various exchanger configurations, as well as various regenerator models. The versatility of ASCE-UMA allows the development analysis of all the fundamental elements of a new prototype as well as the analysis of experimental data by performing a customized and detailed calculation. To test the effectiveness of ASCE-UMA, its performance is verified by analyzing Ross Yoke D-90 models and a GM GPU-3 engine. This is a tool that allows to analyze and comparing the different models and the different existing mechanisms for the multiple configurations of Stirling engines in an easy and intuitive application with a high-quality graphical interface.

RESUMO

Chimeric antigen receptor (CAR) T cells targeting CD19+ B cells have demonstrated efficacy in refractory systemic lupus erythematosus (SLE). Although initial clinical data suggest that anti-CD19 CAR T cell therapy is well tolerated and highly effective, the immunologic consequences of CAR T cell therapy in SLE patients remain unclear. We profiled serum in six refractory SLE patients prior to and 3 months following CAR T cell infusion. Three months post T cell infusion, the inflammatory cytokines IL-6 and TNFα decreased in patient sera. This was accompanied by elevations in serum IL-7 and BAFF. Furthermore, SLE-associated antibodies dropped profoundly in five of six patients. Last, consistent with other reports of CD19 CAR T therapy in B cell malignancies, we were able to show marginal impact of anti-CD19 CART therapy on pre-existing humoral immune responses in SLE patients. Together, these results provide insights into the mechanisms of efficacy of anti-CD19 CAR T cell therapy in SLE.

RESUMO

IMPORTANCE: African swine fever virus (ASFV) is the cause of the current major animal epidemic worldwide. This disease affects domestic pigs and wild boars, has spread since 2007 through Russia, Eastern Europe, and more recently to Western European countries, and since 2018 emerged in China, from where it spread throughout Southeast Asia. Recently, outbreaks have appeared in the Caribbean, threatening the Americas. It is estimated that more than 900,000 animals have died directly or indirectly from ASFV since 2021 alone. One of the features of ASFV infection is hemoadsorption (HAD), which has been linked to virulence, although the molecular and pathological basis of this hypothesis remains largely unknown. In this study, we have analyzed and identified the key players responsible of HAD, contributing to the identification of new determinants of ASFV virulence, the understanding of ASFV pathogenesis, and the rational development of new vaccines.

RESUMO

Adhesive capsulitis, characterized by progressive fibrosis, causes a gradual, painful loss of both active and passive articular motion, leading to the final contracture of the joint capsule. The condition commonly referred to as "frozen ankle" (FA), which Goldman was the first to use, relates to the ankle joint and is challenging to both diagnose and treat. Data acquired from people who suffer from this type of damage in other joints such as the shoulder, hip, and wrist also exists. Despite the fact that a well-defined model for the medical management of FA does not exist, a wide spectrum of local treatments, both surgical and non-surgical, exist. This review gives an overview of the current scientific position of the frozen ankle in terms of evolutionary factors, etiology, the different mechanisms of action involved, current treatment options, and other possible interventions based on recent discoveries of pathophysiological mechanisms. The application of extracorporeal shockwave therapy, stretching exercises, and corticosteroid injections combined with physical therapy modalities that enhance pain management, range of motion, and functional capacity is highly advisable for the treatment of adhesive capsulitis, commonly known as "frozen joints". Furthermore, the addition of interventions both impacting and analyzing chronic hypoxia, low-grade inflammation, and sedentary life is proposed.

RESUMO

The purpose of this study was to analyze the changes in the elasticity and temperature of the patellar tendon produced by the application of a radiofrequency at 448 kHz (CRMR) just after and 7 days after the intervention. An open controlled clinical trial was used with participants being recruited from a private clinic. The experimental group (n = 22) received a 448 kHz CRMR treatment while the control group (n = 22) did not receive any type of intervention. Quantitative ultrasound strain elastography (SEL) and thermography were used to collect data from 4 different areas of the patellar tendon. These areas were measured at the start (T0), just after (T1), and seven days after (T2) the intervention. There were thermal changes immediately after the intervention (p < 0.001). In addition, when the measurements were collected just after the intervention and seven days after they were analyzed, significant changes (p < 0.001) in temperature were observed in the tendons of both groups. Finally, a low but significant association (r = 0.434, p < 0.04) was observed between the elastic properties of the tendon at its insertion in the patella and thermal changes just after the 448 kHz intervention.

RESUMO

BACKGROUND: Hematopoiesis, the process of blood cell formation involves on a complex network of transcription factors. Among them, the CCAAT-enhancer-binding protein alpha (CEBPA) plays a crucial role in maintaining the balance between myeloid proliferation and differentiation. Imbalances in this network can lead to disrupted differentiation and contribute to the development of malignant diseases. AIM: Understanding of disease development and explore potential therapeutic strategies for hematological disorders associated CEPBA gen. MATERIALS AND METHODS: The research involved a comprehensive analysis of CEBPA gene mutations in the context of acute myeloid leukemia (AML). This encompassed a thorough exploration of point mutations and double mutations in AML patients. RESULTS: In the context of acute myeloid leukemia (AML), mutations in the CEBPA gene, especially point mutations, are frequently observed. A significant number of AML patients present with double mutations in CEBPA, which have been linked to a more favorable prognosis in terms of overall survival and event-free survival. These patients also tend to exhibit enhanced responsiveness to treatment. DISCUSSION: Unraveling the intricate interplay of transcription factors, particularly CEBPA, holds significant implications for decoding the mechanisms governing hematopoiesis. This understanding offers a potential avenue for deciphering disease development and devising novel therapeutic strategies for hematological disorders. CONCLUSION: The findings underscore that CEBPA mutations correlate with enhanced overall survival and event-free survival, with relevance to those presenting within the bZip framework. This knowledge may contribute to advancing personalized treatments for hematological conditions.

RESUMO

INTRODUCTION: Psychosocial functioning is closely associated with psychopathology and wellbeing in different populations, particularly adolescents. Despite its relevance, measures assessing psychosocial functioning in healthy adolescents are scant as most focus on adults or clinical populations. We evaluated the psychometric properties of the Multidimensional Adolescent Functioning Scale (MAFS), a self-report questionnaire created to assess three dimensions of psychosocial functioning ('general functioning', 'family-related functioning', and 'peer-related functioning') in adolescents from the general population. METHODS: After translation and cultural adaptation, we administered the Spanish MAFS to 619 adolescents aged 14 to 19. We assessed the factor structure, internal consistency, and associations with depressive symptoms, suicidal ideation, cognitive-behavioral skills, cognitive reappraisal (CR), and expressive suppression (ES). We additionally tested for measurement invariance based on biological sex. RESULTS: The original three-factor structure showed the best fit. Internal consistency was good for the total scale (ω = 0.874; α = 0.869; GLB = 0.939, rM=0.216) and for all subscales (ω = 0.806-0.839; α = 0.769 to 0.812; GLB = 0.861-0.873). Correlations between all three MAFS subscales were significant, ranging between 0.291 and 0.554. All MAFS subscales correlated positively and significantly with cognitive-behavioral skills and adaptive regulatory strategies and negatively with depressive symptoms and suicidal ideation. CONCLUSION: The Spanish MAFS translation is a valid and reliable self-report measure to assess three domains of psychosocial functioning in adolescents aged 14-19 from the general population.

RESUMO

PURPOSE: This study was aimed at verifying both the intraobserver and interobserver reliability of measuring plantar fascia stiffness for a given image in healthy active adults. METHODOLOGY: This study is reported following the Guidelines of Reporting Reliability and Agreement Studies. A total of 20 plantar fascia from healthy volunteers were analyzed. The thickness of the plantar fascia was measured vertically from the anterior edge of the inferior calcaneal border to the inferior border of the plantar fascia and the ultrasound elastography measurement was taken at the calcaneal insertion of the plantar fascia with the region of interest one centimeter away from the insertion. RESULTS: The ultrasound strain elastography measurements: the right intraobserver 1 showed an ICC value of 0.9 and the left intraobserver 1 showed an ICC value of 0.78, while the right intraobserver 2 showed an ICC value of 0.91 and the left intraobserver 2 showed an ICC value of 0.83. Interobserver measurements showed excellent reliability with a right ICC value of 0.8 and a left ICC value of 0.9 for the plantar fascia thickness measurements. DISCUSSION: The results of this study showed a strong correlation between left and right plantar fascia thickness. The intraobserver reliability was excellent for both plantar fascia ultrasound strain elastography and thickness measurements, with interobserver measurements showing excellent reliability.

RESUMO

Due to the cognitive decline associated with aging, it is necessary to determine the variables involved in this process to implement preventive actions to avoid or help slow the progression of cognitive decline to dementia in older adults. This is a priority in the current pandemic situation, due to the consequences of periods of confinement due to COVID-19. To address these challenges, this study was conducted through Information and Communication Technologies (ICTs), by adapting an in-person assessment protocol into an online Tele neuropsychological consultation. The correlation between autonomy and cognitive performance variables is analyzed in 47 Mexican subjects over 60 years of age. The results of the statistical analyses suggest a moderate correlation between the level of autonomy and cognitive performance (with MOCA and Clock Drawing Test), significant correlation values are outlined in some of the variables reviewed, and interesting data were found in the correlation of cognitive reserve with cognitive decline and the educational level from the participants. Finally, future analysis is proposed of the sensitivity of screening tests (CDT) to find indicators of Mild Cognitive Impairment (MCI) in this population that is not detected in classical tests (MOCA). Developing ICT-based screening protocols for the elderly may be a key tool in these coronavirus times or under any given circumstances.

RESUMO

The main objective of this literature review was to analyze the efficacy of (PBM) therapy application on subjects with chronic pain and inflammation, and furthermore, to evaluate the methodological quality of the collected literature. The search was conducted using five databases: PubMed, ProQuest, Scopus, Web of Science, and PEDro. The keywords "low level laser therapy", "chronic pain", and "inflammation" provided the selection of RCTs that were published within the last 5 years, conducted in humans, and written in English. The PEDro Internal Validity Scale (IVS) checklist was used to evaluate the risk of bias in the included studies. A total of 11 articles were selected, all of them RCTs. Of the articles, five showed that PBM positively influences chronic pain, while another showed the same but only in the short term. In two other articles, the patient's inflammation improved markedly. In one article there was no improvement in chronic pain and in another, there was no improvement in inflammation. Four articles demonstrated that PBM is beneficial in acute pain. Furthermore, six studies were given an "excellent" score and the remaining five a "good" score based on the IVS. Photobiomodulation has beneficial effects on chronic pain and inflammation, although more research needs to be completed in this line for this to be clarified as the existence of RCTs on this subject is limited.

RESUMO

Direct FXa inhibitors are an important class of bioactive molecules (rivaroxaban, apixaban, edoxaban, and betrixaban) applied for thromboprophylaxis in diverse cardiovascular pathologies. The interaction of active compounds with human serum albumin (HSA), the most abundant protein in blood plasma, is a key research area and provides crucial information about drugs' pharmacokinetics and pharmacodynamic properties. This research focuses on the study of the interactions between HSA and four commercially available direct oral FXa inhibitors, applying methodologies including steady-state and time-resolved fluorescence, isothermal titration calorimetry (ITC), and molecular dynamics. The HSA complexation of FXa inhibitors was found to occur via static quenching, and the complex formation in the ground states affects the fluorescence of HSA, with a moderate binding constant of 104 M-1. However, the ITC studies reported significantly different binding constants (103 M-1) compared with the results obtained through spectrophotometric methods. The suspected binding mode is supported by molecular dynamics simulations, where the predominant interactions were hydrogen bonds and hydrophobic interactions (mainly π-π stacking interactions between the phenyl ring of FXa inhibitors and the indole moiety of Trp214). Finally, the possible implications of the obtained results regarding pathologies such as hypoalbuminemia are briefly discussed.

RESUMO

OBJECTIVE: We examined the relationships between eating disorders symptoms (EDs), suicidal ideation, depressive and anxiety symptoms, and perceived family functioning in a sample of university students aged 18-25 years (N = 397). METHOD: Assessment of symptoms was carried out with the Eating Disorder Diagnostic Scale, Beck Anxiety Inventory and Beck Depression Inventory, among others. We explored the associations between the domains using network analysis. RESULTS: We found that physical anxiety symptoms, followed by cognitive and physical depressive symptoms showed the greatest centrality in the current network. Perceived family functioning was negatively related to eating disorder symptoms. DISCUSSION: We provide evidence regarding the relevant role of anxiety and depression symptoms in the presentation of ED symptoms in university students. These findings provide new insights to improve preventive interventions to timely reduce symptoms and risk factors associated with EDs. PUBLIC SIGNIFICANCE: Using a network approach, we found specific associations between physical anxiety symptoms, cognitive and physical depressive symptoms, eating disorders symptoms, suicidal ideation and perceived family functioning in university students. These variables can be potential targets to develop evidence-based preventive strategies in this population. A better understanding of these complex associations and the role of family variables could enhance the effectiveness of interventions in both clinical and educational settings.

RESUMO

Photodynamic therapy of cancer (PDT) is a therapeutic technique, minimally invasive, which is currently used to treat cancerous lesions and tumors that have been in the spotlight for its potential over the recent decades. Nonetheless, PDT still needs further development to become a first-option treatment for patients. This review compiles recent progress in several aspects of the current research in the constantly growing area of PDT to overcome the main challenges as an attempt to serve as a guide and reference for newcomers into this research area. This review has been prepared to highlight the use of chemical modifications on photosensitizers to improve their solubility, photostability, selectivity and phototoxicity. Additionally, the use of liposomes and cavitands as drug delivery systems to aid in the biodistribution and bioaccumulation of photosensitizers is presented. Also, the combination of PDT with chemotherapy or immunotherapy as an option to boost and improve treatment outcomes is discussed. Finally, the inhibition of antioxidant enzymes as a strategy for a synergistic effect to ameliorate the performance of the photosensitizers in PDT is presented as an alternative for future researchers.

RESUMO

Psychotic experiences are associated with increased risk for suicide. Despite this well-established finding, very little is known about factors that contribute to this relationship. The current study investigated the relationship between psychotic experiences, emotion regulation, and suicidal ideation among 1,590 Chilean adolescents in the general population. Participants completed self-report measures of psychotic experiences (Community Assessment of Psychic Experiences), emotion regulation (Emotion Regulation Questionnaire), depression (Patient Health Questionnaire-9), and suicidal ideation (Columbia Suicide Severity Rating Scale). Statistical analyses included Mann-Whitney U tests, point-biserial correlations, logistic regression, and moderation analyses. Results suggest that paranoid ideation, bizarre experiences, and perceptual abnormalities were moderately associated with suicidal ideation. Additionally, greater expressive suppression and cognitive reappraisal were associated with suicidal ideation. Results from the logistic regression indicate that paranoid ideation, perceptual abnormalities, and expressive suppression have the strongest relationship with suicidal ideation, even when controlling for depression and relevant demographic variables. Additionally, paranoid ideation interacted with expressive suppression to predict suicidal ideation, with expressive suppression having the strongest relationship with suicidal ideation when paranoid ideation was low to moderate. Taken together, these findings support the broader literature suggesting that emotion regulation might be a transdiagnostic risk factor for suicidal ideation. Additional longitudinal research is needed to examine whether expressive suppression and other maladaptive emotion regulation strategies serve as a mechanism for suicidal ideation both in the general population and among individuals with psychotic experiences.

RESUMO

African swine fever (ASF) is an obligated declaration swine disease, provoking farm isolation measures and the closing of affected country boarders. ASF virus (ASFV) is currently the cause of a pandemic across China and Eurasia. By the end of 2019, ASF was detected in nine EU Member States: Bulgaria, Romania, Slovakia, Estonia, Hungary, Latvia, Lithuania, Poland and Belgium. The affected area of the EU extended progressively, moving mostly in a southwestern direction (EFSA). Inactivated and/or subunit vaccines have proven to fail since certain virus replication is needed for protection. LAVs are thus the most realistic option, which must be safe, effective and industrially scalable. We here generated a vaccine prototype from the Arm/07/CBM/c2 genotype II strain, in which we have deleted the EP402R (CD2v) and A238L genes by CRISPR/Cas9 in COS-1 cells, without detectable further genetic changes. The successful immunization of pigs has proven this vaccine to be safe and fully protective against the circulating Korean Paju genotype II strain, opening the possibility of a new vaccine on the market in the near future.
