Fractional flow reserve in patients with intermediate values of Duke Treadmill Score and borderline coronary lesions

Despite the wide usage of exercise ECG tests and Duke Treadmill Score (DTS) in clinical practice, no comparison between this scoring system and Fractional Flow Reserve (FFR) has yet been made, particularly in cases of angiographically verified borderline lesions. Thirty patients with single coronary lesions and angiographically assessed borderline stenosis (between 30-70%) and previously calculated intermediate values of DTS between -10 to +4 were examined using FFR. Adequate specificity and sensitivity (0.769 and 0.556, respectively) were in a more narrow range of -0.5 to -10. Sex and age did not have an influence on the DTS values. There was a correlation between the values of FFR and age (r=0.395, p=0.031) and between angiographic assessment of stenosis and quantitative coronary angiography (QCA) (r=0.648, p<0.0001). In the study population, a decision on revascularization could not be based solely on angiographic or QCA assessment of the artery or on the values of DTS

Attitudes of Primary School Teachers Toward Inclusive Education

Background: The aims of our study are related to examining the relevance of teachers' attitudes toward the implementation of inclusive education. In addition, its subject is related to the implications on inclusive education policies, limitations of the existing study along with the recommendations for our future research endeavors. Methods: The research is a cross-sectional study type. The sample included 64 primary school teachers in the lower grades of primary school (grades 1–4), selected by using simple random sampling, in three primary schools on the territory of Belgrade, Serbia in 2021 (26, 17, and 21 primary school teachers). The Questionnaire for Teachers, which was used as a research instrument, was taken from the Master's Thesis Studen Rajke, which was part of the project “Education for the Knowledge Society” at the Institute for Educational Research in Belgrade. Dependent variables measured in the study referred to the attitudes of primary school teachers toward inclusive education. Categorical variables are represented as frequencies and the Chi-square test was used to determine if a distribution of observed frequencies differed from the expected frequencies. Results: One in three teachers (32.8%) thought that inclusion was useful for children with disabilities (29.7%), of them thought that schools did not have the conditions for inclusive education, whereas one in four teachers (25.0%) believed that inclusion was not good. No statistically significant differences were found in the attitudes of professors, when observed in terms of their gender, age and length of service. Conclusion: Investing more resources and time in developing and implementing special education policies can promote successful inclusive education

Acute Cardiovascular Manifestations in 286 Children With Multisystem Inflammatory Syndrome Associated With COVID-19 Infection in Europe

Background: The aim of the study was to document cardiovascular clinical findings, cardiac imaging, and laboratory markers in children presenting with the novel multisystem inflammatory syndrome associated with coronavirus disease 2019 (COVID-19) infection. Methods: This real-time internet-based survey has been endorsed by the Association for European Paediatric and Congenital Cardiologists Working Groups for Cardiac Imaging and Cardiovascular Intensive Care. Children 0 to 18 years of age admitted to a hospital between February 1 and June 6, 2020, with a diagnosis of an inflammatory syndrome and acute cardiovascular complications were included. Results: A total of 286 children from 55 centers in 17 European countries were included. The median age was 8.4 years (interquartile range, 3.8-12.4 years) and 67% were boys. The most common cardiovascular complications were shock, cardiac arrhythmias, pericardial effusion, and coronary artery dilatation. Reduced left ventricular ejection fraction was present in over half of the patients, and a vast majority of children had raised cardiac troponin when checked. The biochemical markers of inflammation were raised in most patients on admission: elevated C-reactive protein, serum ferritin, procalcitonin, N-terminal pro B-type natriuretic peptide, interleukin-6 level, and D-dimers. There was a statistically significant correlation between degree of elevation in cardiac and biochemical parameters and the need for intensive care support (P<0.05). Polymerase chain reaction for severe acute respiratory syndrome coronavirus 2 was positive in 33.6%, whereas immunoglobulin M and immunoglobulin G antibodies were positive in 15.7% cases and immunoglobulin G in 43.6% cases, respectively, when checked. One child in the study cohort died. Conclusions: Cardiac involvement is common in children with multisystem inflammatory syndrome associated with the Covid-19 pandemic. The majority of children have significantly raised levels of N-terminal pro B-type natriuretic peptide, ferritin, D-dimers, and cardiac troponin in addition to high C-reactive protein and procalcitonin levels. In comparison with adults with COVID-19, mortality in children with multisystem inflammatory syndrome associated with COVID-19 is uncommon despite multisystem involvement, very elevated inflammatory markers, and the need for intensive care support.info:eu-repo/semantics/publishedVersio

The prevalence and socioeconomic correlates of depressive and anxiety symptoms in a group of 1,940 Serbian university students

© 2016, Institut za Vojnomedicinske Naucne Informacije/Documentaciju. All rights reserved. Background/Aim. Mental health of university students is under increasing concern worldwide, because they face challenges which predisposes them to depression and anxiety. The aim of this study was to identify demographic and socioeconomic variables associated with depressive and anxiety symptoms among university students. Methods. This cross-sectional study on 1,940 university students was performed using a questionnaire including demographic and socioeconomic variables, Beck Depression Inventory and Beck Anxiety Inventory. Results. The prevalence of depressive symptoms in students was 23.6%, while the prevalence of anxiety symptoms was 33.5%. The depressive symptoms were significantly related to the study year (p = 0.002), type of faculty (p = 0.014), satisfaction with college major choice (p < 0.001), satisfaction with grade point average (p < 0.001). Female students (odds ratio – OR = 1.791, 95% confidence interval – CI = 1.351–2.374), older students (OR = 1.110, 95% CI = 1.051-1.172), students who reported low family economic situation (OR = 2.091, 95% CI = 1.383–3.162), not owning the room (OR = 1.512, 95% CI = 1.103–2.074), dissatisfaction with graduate education (OR = 1.537, 95% CI = 1.165–2.027) were more likely to show depressive symptoms. The anxiety symptoms were significantly related to study year (p = 0.034), type of faculty (p < 0.001), family economic situation (p = 0.011), college residence (p = 0.001) satisfaction with the college major choice (p = 0.001), and satisfaction with graduate education (p < 0.001). Female students (OR = 1.901, 95% CI = 1.490–2.425), and students who reported parents high expectations of academic success (OR = 1.290, 95% CI = 1.022–1.630) were more likely to show anxiety symptoms. Conclusion. This is one of the largest study examining mental disorders in a sample of university students in Serbia. These findings underscore the importance of early detections of mental problems and prevention interventions in university students

Clinical usefulness of ^99mTc-HYNIC-TOC, ^99mTc(V)-DMSA, and ^99mTc-MIBI SPECT in the evaluation of pituitary adenomas

© 2018 Wolters Kluwer Health, Inc. All rights reserved. Background The aim of this study was to evaluate the behavioral uptake and ability to diagnose pituitary adenoma (PA) using tumor-seeking radiopharmaceuticals, and to provide a semiquantitative analysis of tracer uptake in the pituitary region. Patients and methods The study included 33 (13 hormonally active and 20 nonfunctioning) patients with PA and 45 control participants without pituitary involvement. All patients (n=78) underwent single photon emission computed tomography (SPECT) imaging with technetium-99m-labeled hydrazinonicotinyl-tyr 3 -octreotide (99mTc-HYNIC-TOC), dimercaptosuccinic acid (99mTc(V)-DMSA) and hexakis-2-methoxyisobutylisonitrile (99mTc-MIBI). A semiquantitative analysis of abnormal uptake was carried out by drawing identical regions of interest over the pituitary area and the normal brain on one transverse section that shows the lesion most clearly. The pituitary uptake to normal brain uptake (P/B) ratio was calculated in all cases. Results The result of this study confirms that the SPECT semiquantitative method, with all three tracers, showed statistically significant differences between the PA group and the controls. However, 99mTc-HYNIC-TOC scintigraphy could have the highest diagnostic yield because of the smallest overlap between the P/B ratios between adenoma versus nonadenoma participants (the receiver operating characteristic curve P/B ratio cut-off value was 13.08). In addition, only 99mTc-MIBI SPECT have the diagnostic potential to detect secreting PAs, with statistically significant differences between groups (P<0.001), with an receiver operating characteristic curve P/B ratio cut-off value of 16.72. Conclusion A semiquantitative analysis of increased focal tracer uptake in the sellar area showed that 99mTc-HYNIC-TOC is a highly sensitive and reliable tumor-seeking agent for detecting PA, whereas 99mTc-MIBI SPECT is a highly sensitive and specific method in differentiating hormone-secreting pituitary tumor

The impact of somatic symptoms on depressive and anxiety symptoms among university students in central Serbia

© 2018, Inst. Sci. inf., Univ. Defence in Belgrade. All rights reserved. Background/Aim. Depression and anxiety problems are a major public health concern due to their high prevalence rates, difficult treatment, and often chronic course. This study examined the impact of somatic symptoms on depressive and anxiety symptoms among university students in Serbia. Methods. A cross-sectional study was performed among 1,940 students using a questionnaire specially designed for this study which included presence of Somatic and Non-specific Mental Symptoms (SNMS), Beck Depression Inventory and Beck Anxiety Inventory. The presence of somatic and associated non-specific mental symptoms over the last six months served as the basis for creating a new variable called SNMS score. Results. Receiver operating characteristic (ROC) curve showed that the SNMS score might be a very good marker for the distinction of students with or without depressive symptoms (area = 0.754, p < 0.05). The threshold value was 8.50 (sensitivity 67.6%, specificity 69.4%). Binary logistic regression showed that Odds ratio was 1.052 [95% confidence interval (CI) 1.045–1.059], which means that an increase in the value of the SNMS score by 1 increases the risk of depressive symptoms by 5.2%. ROC curve showed that the SNMS score might be an excellent marker for the distinction of students with or without anxiety symptoms (area = 0.800, p < 0.05). Limit value (cut-off) was 7.50 (sensitivity 74.2%, specificity 71.6%). Binary logistic regression showed that odds ratio was 1.056 (95% CI 1.049–1.064), which means that increasing the value of SNMS score by 1 increases the risk of anxiety symptoms by 5.6%. Conclusion. The SNMS score might be a state marker for the screening and distinction of students with depressive symptoms, and excellent state marker for screening and making distinction between students with anxiety symptoms and the students who do not have these symptoms

Is there association between left atrial function and functional capacity in patients with uncomplicated type 2 diabetes?

We sought to investigate the relationship between phasic left atrial function (LA) and functional capacity in the patients with type 2 diabetes (DM). This cross-sectional investigation included 72 controls and 64 uncomplicated DM subjects. All participants underwent echocardiographic examination and cardiopulmonary exercise testing. Total and passive LA emptying fractions (EF), demonstrating LA reservoir and conduit function, were significantly lower in DM patients than in controls. Active LA EF, the parameter of LA booster pump function, was similar between DM and controls. Total and positive LA strains, corresponding with reservoir and conduit function, were also significantly reduced in DM subjects comparing with controls. However, negative LA strain—parameter of LA booster pump function, was significantly increased in DM patients in comparison with controls. Peak oxygen consumption was significantly reduced and ventilation/carbon dioxide slope was elevated in DM patients. In the whole study population LA global longitudinal strain was associated with heart rate recovery in the first minute, peak oxygen consumption and ventilation/carbon dioxide slope independently of other clinical parameters and LV hypertrophy and LV diastolic function. In conclusion, LA phasic function and functional capacity were significantly impaired in the patients with DM. LA longitudinal strain, but not LA volume index, was independently related with functional capacity in the whole study population. Our results suggest that evaluation of LA function and functional capacity could detect subclinical target organ damage and prevent development of further complications in uncomplicated DM patients
