Background: COVID-19 is a multi-systemic infectious disease. Nearly 20%-30% of hospitalized patients have evidence of acute myocardial involvement, portending a poorer prognosis. However, information about the long-term effects of the disease on cardiac functions is sparse. As a result, there is a growing concern about the cardiac sequelae of COVID-19 among survivors. This study aimed to investigate the effects of prior mild-moderate COVID-19 infection on cardiac functions, using speckle tracking echocardiography. Methods: Patients who have been diagnosed with COVID-19 within the previous 6 months and age-, sex-, and risk factor-matched healthy adults were included. All patients underwent a comprehensive echocardiographic examination. Both conventional and 2-dimensional speckle tracking echocardiographic measurements were performed. Serum cardiac biomarkers were also obtained on the day of the echocardiographic study. Results: Compared with healthy controls, COVID-19 survivors had similar left and right ventricular longitudinal strain values at 6 months. Also, left and right atrial peak systolic strain values did not differ between the groups. Conclusion: Our study is valuable in putting forth the unaffected ventricular and atrial functions on long term in uncomplicated COVID-19 cases and may decrease the survivors' anxiety and the number of unnecessary applications to cardiology clinics.

Although the association between theory of mind (ToM) and aggression has been theorized, empirical findings have not revealed a clear link between these constructs. In the current meta-analytic review, we integrated findings from 83 studies (141 effect sizes) involving 41,650 participants from 18 countries to elucidate the association between ToM and aggression in typically developing children, adolescents, and adults. We found a significant negative association between ToM and aggression overall (r = −0.15). Moreover, each type and function of aggression were negatively associated with Theory of Mind (ToM). Bullying—a distinct form of aggression—was not associated with ToM. The strength of the association between overall aggression and ToM varied as a function of methodological variables: First, studies that used self-report questionnaires to measure ToM and aggression yielded the strongest effect sizes, compared to those that used task-based assessments or questionnaires completed by others (parents, teachers, peers). Second, there was a difference in the ToM measurement with the measures examining ToM with non-false belief understanding tasks yielding a stronger mean effect than those that focused exclusively on false-belief understanding. Third, the magnitude of the negative association was found to increase with participants' age, though significant negative associations between ToM and aggression held across the lifespan. These results point to the critical link between ToM and aggressive tendencies and suggest the value in implementing interventions to improve mental state understanding across the age range to foster positive social interactions. • We integrated findings from 83 studies (141 effect sizes) to elucidate the association between ToM and aggression in typically developing children, adolescents, and adults. • We found a significant negative association between ToM and aggression overall. • The association was significant and negative across all age groups. • The association was negative and significant for different forms and functions of aggression. • There were significant moderators of the association such as measurement of aggression and ToM.

Objectives: Research examining disruptive behaviors in clinical groups of preschool and school-aged children has consistently revealed significant difficulties in their emotion knowledge and empathy but intact performance in their theory-of-mind (ToM). However, it is largely not known if these difficulties in emotion knowledge and empathy as opposed to ToM are specific to extreme forms of disruption in clinical groups or rather represent broad deficiencies related to disruptive behaviors in general, including the milder levels exhibited by typically developing children. Milder disruptive behaviors (e.g., whining, arguing, rule-breaking and fighting) in peer contexts might relate to normative variations in socio-cognitive and emotional skills like ToM, emotion knowledge and empathy. To illuminate whether the same pattern of relations observed in clinical samples would arise in typical development, this study aims to examine the role of ToM, emotion knowledge and empathy in typically developing preschoolers' disruptive behaviors. Methods: We used individual tasks to measure 116 typically developing Turkish preschoolers' ToM, emotion knowledge (understanding anger and sadness) and empathy for pain, and received mothers' reports about children's levels of disruptive behavior in peer contexts. Results: Path analysis showed that among these skills, it was only empathy which predicted disruptive behaviors significantly (β = −0.25, p< 0.05). Understanding sadness predicted higher empathy (β = 0.18, p< 0.05) and higher empathy predicted lower disruptive behaviors, but the mediation of empathy in the link between understanding sadness and disruptive behavior was not significant (β = −0.05, p> 0.05, 90% CI = −0.106, 0.001). Conclusions: Overall, our results indicate that empathizing with others' emotions is more important than understanding their mental states and emotions for lower disruptive behaviors.

Predatory journals, which are a major concern of the academic community, generally do not properly fulfill the reviewing and editorial processes which are the most important pillars of scientific communication. In line with the principle of the accumulation of science, the papers that have not been faithfully reviewed in these journals cause a bad effect on the scholarly communication. In this study, the impact of 17 journals with addresses in Turkey in Cabells' Predatory Report (formerly Cabells' Journal Blacklist) to the literature were examined. For this purpose, the journal and article level descriptive statistics were examined for the aforementioned journals, and analyses were made for the citations from the papers published in the journals indexed in the Web of Science citation database. A total of 3427 papers were published in these journals, which started to be published between 2010 and 2015, and 389 citations were made to these papers from the journals listed in the WoS. Such highest citations come from Turkey (24.16%), then China (7.20%) addressed papers. In addition, although there are no papers in fields such as art, humanities and physics, it has been seen that there are citations to papers from these fields. This is important in terms of showing the widespread impact of science. A paper published without serious peer review in any predatory journal affects all fields of science in terms of its method, findings and discussions. Therefore, to reduce the misleading or false effect of predatory journals on the literature, a more skeptical behavior should be displayed about citing the papers published in these journals.

The possibility of creating and easily distributing something via a digital platform creates an enormous material volume. With the increase of scientific publications it becomes harder for scholars to choose the most related and significant resources from the others (Henning & Gunn, 2012). Bibliometrics measures the impact of scholars between each other, but the impact of articles across the entire web is not limited by this. On the other hand, altmetrics measures the impact of articles from the web, alongside bibliometric data. The aim of this study is to investigate the probable relationships between traditional metrics and altmetrics by analysing the PLoS Article-Level Metric (ALM) dataset. [ABSTRACT FROM AUTHOR]

Purpose: Cardiac resynchronization therapy (CRT) positively affects the improvement of functional mitral regurgitation (MR) in patients with heart failure with reduced ejection fraction (HFrEF). However, geometric changes in the mitral valve apparatus, subvalvular structures and their contribution to improving mitral regurgitation after CRT have not been clearly defined. Our study aimed to evaluate the geometric parameters of mitral valve apparatus measured with three‐dimensional (3D) transesophageal echocardiography (TEE) before CRT implantation and to determine the parameters predicting the improvement of MR after CRT. Methods: In this prospective study, we included thirty patients with moderate or severe MR and HFrEF planned for CRT implantation who had an indication for TEE. Before CRT implantation, effective regurgitant orifice (ERO) and regurgitant volume (RV) measurements were performed. Detailed quantitative measurements of the mitral valve were done from recorded images by 3D TEE. ERO and RV measurements were repeated to evaluate MR at the end of the third month. Results: There were no significant changes in left ventricular EF and left ventricular diameters at third‐month follow‐up, whereas ERO and RV values were decreased. The posterior leaflet angle was higher in the non‐responder group than the responder group (28.93 ± 8.41 vs 41.25 ± 10.90, p = 0.006). The posterior leaflet angle was an independent predictor of decreased RV and ERO. Conclusion: Among HFrEF patients with moderate or severe functional MR who underwent CRT implantation had a lower posterior leaflet angle, which was measured by 3D TEE, in the patient group whose MR improved after CRT.

Background Nondipping blood pressure pattern carry a high risk of cardiovascular and cerebrovascular complications due to a higher cumulative pressure overload. We aimed to define the role of strain analysis for detecting subclinical left ventricular systolic dysfunction in recently diagnosed nondipper and dipper hypertensive patients with normal left ventricular systolic function. Methods Study population consisted of two groups of patients, Group 1: 45 dipper patients and Group 2: 43 nondipper patients. Global and segmental two-dimensional longitudinal strain analysis were measured by speckle tracking method. Results The analysis of two-dimensional left ventricular global longitudinal strain and strain rates showed that there was a significant difference between groups (−18.1%±3.1% for nondippers vs −20.5%±2.4% for dippers, P<.001 for global longitudinal strain and −1.2±0.2 1/s for nondippers vs −1.31±0.16 1/s for dippers, P<.001 for global longitudinal strain rate). The nighttime systolic, diastolic, and mean blood pressure measurements were significantly higher in the nondipper group. Nocturnal dipping rates were statistically different between the groups ( P<.001). Interventricular septum, posterior wall thickness, relative wall thickness, left atrial dimension, left ventricular mass, and mass index were higher in the nondipper group. Multivariate analysis demonstrated left atrium size, nocturnal dipping rate, daytime mean blood pressure, and nighttime systolic, diastolic, and mean blood pressure as independent predictors of global longitudinal strain. Conclusion In our study, two-dimensional speckle tracking examination showed that the left ventricular systolic function is impaired even in the subclinical period in recently diagnosed nondipper hypertensive patients with deformational analysis.
