Examining of the effects of aerobic dance and step dance exercises on some hematological parameters and blood lipids

The aim of the study was to examine the the effects of aerobic and step dance exercises on hematological and blood lipids parameters. 32 university students were voluntarily participated in this study. They were randomly assigned to aerobic dance (N=16) and step dances (N=16). All groups were participated an hour aerobic or step dance exercise session 2 times in a week during 3 months. Wilcoxon Sign test was used to analyze pretest and posttest results of variables. As results, significant differences were found in the pre- and post-intervention scores for triglycerides (TC), red blood cell (RBC), and hematocrit (HCT) in Step dance group. Although there were decreases in triglycerides levels for both aerobic dance and step dance groups, only significant reduction was found in step dance group. Step dance exercises was better than aerobic dance in terms of increasing RBC and decreasing cholesterol, low density lipoproteins (LDL) cholesterol level. Aerobic dance exercises were better than step dance in terms of increasing high density lipoproteins (HDL). Moreover, when comparing the level of decreasing of Hemoglobin (HGB) significantly, aerobic dance group were better than step dance group. HCT increased significantly more in step dance group as compared with aerobic dance group. Step dance cause more increment than aerobic dance in terms of platetes (PLT) level. The data of this study indicates that step dance is more effective than aerobic dance in terms of decreasing LDL cholesterol, triglycerides and cholesterol for university students

Non–Vitamin K Antagonist Oral Anticoagulants, Clinical Use, Real-World Data, and Reversal of Anticoagulant Effect

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in clinical practice and is associated with a higher risk of thromboembolic events. CHA2DS2VASc score enables identification of those patients with AF who will most benefit from anticoagulation therapy and low-risk patients with AF who do not need any antithrombotic therapy. Antithrombotic drugs especially oral anticoagulants (OACs) are the mainstay of therapy to prevent stroke in patients with AF. Although vitamin K antagonists (VKAs) were the only available drugs for decades, numerous non–vitamin K antagonist oral anticoagulants (NOACs) have been developed and marketed for stroke prevention in recent years. The risk of stroke was reported to decline up to 68 % with OAC therapy, associated with good anticoagulation control with VKAs, assessed by time in therapeutic range (TTR). In low TTR values, VKAs were found to be associated with severe complications, and a minimum TTR of 58 % should be achieved to expect a net benefit from being on OAC therapy. Narrow therapeutic index, drug-drug interactions, and the need for close monitoring are the main disadvantages of VKAs, and management of patients have dramatically improved after the introduction of NOACs. NOACs have a more predictable anticoagulant affect which allows a fixed-dose regimen. The efficacy and safety of NOACs have been shown not only in large randomized controlled clinical trials but also in observational studies. The main advantages of NOACS such as “fixed-dose regimen” and “no need for regular anticoagulant therapy monitoring” may also be the Achilles heel of the use of these agents. Fixed-dose regimen may not be appropriate for elderly, for patients with chronic kidney disease, and for patients using interacting drugs. Adherence to NOAC therapy is another concern as it may be as low as 50 % in the chronic use of cardiovascular drugs, especially if the drug has no apparent affect to the patient. Thus, appropriate use of OACs among non-valvular AF (NVAF) patients is essential for stroke prophylaxis. We intended to review the use of OAC therapy among (NVAF) patients

Investigation of agility performance on 10-12 years soccer players

This research was carried out for investigation of 10-12 age soccer players’ agility performance according to age. 53 male soccer players attended in this research voluntarily. Illinois agility test was used in the assessment of agility performance. Collected data was recorded in SPSS program. One Way Variance Analyze (ANOVA) was used for determination of differences in different group soccer players. When difference was discerned among groups, Tukey HSD analyses were used for detecting which groups cause this difference. Significance level was accepted as p<0.05. According to research results, significant differences were determined among 10, 11 and 12 age group soccer players’ agility performances (p<0.01). The sources of differences were those, 12 age group soccer players according to 10 and 11 age group showed better performances. Consequently, It can be said that agility feature consisting suddenly stop, change direction and acceleration actions are effected by age in these groups

STEAM MAKERSPACE: REFLECTIONS FROM TEACHERS AND CHILDREN

  Makerspaces function as dynamic learning environments abundant in stimuli that enhance and augment Science, Technology, Engineering, Art, and Mathematics (STEAM) education. These collaborative spaces serve as crucibles for children's learning where they gather, guided by their interests, to work, play, experiment, explore, and create in unison. This study endeavors to investigate teachers' perspectives on the utilization of STEAM makerspaces and further observe children's engagement within these contexts. Our research employed a phenomenological approach, a qualitative research methodology. Data were collected using nominal focus group interviews and direct observation techniques. The study findings underscored the significant role of STEAM makerspaces as stimulating learning environments. These spaces were found to foster children's creativity and imagination through the diverse range of materials they house. Furthermore, the comfortable and inclusive atmosphere within the STEAM makerspaces promoted a sense of belonging amongst the children, contributing to their social and emotional wellbeing. The study also emphasized that STEAM makerspaces cater to comprehensive developmental facets, specifically enhancing cognitive development, creativity, imagination, and self-confidence in children. Moreover, these innovative learning environments encourage active child participation, providing an array of opportunities for hands-on, experiential learning

Intracardiac tumors: Results from a single heart center

Background: This study aims to present the results of surgical treatment of intracardiac tumors in our cardiac surgery center. Methods: Data of 21 patients with intracardiac tumors (15 males, 6 females; median age 60.9 years; range 35 to 87 years) who underwent surgery between April 2006 and May 2015 were retrospectively analyzed. The patients were diagnosed preoperatively by transthoracic echocardiography and computed tomography or magnetic resonance imaging. Results: The mean follow-up was 27.85 months. Of 21 patients, 12 had benign tumors and nine had malignant tumors. Of the benign tumors, nine were myxomas, one was an intramuscular lipoma, one was an interatrial septal lipoma, and one was a papillary fibroelastoma. Of the malignant tumors, eight were metastatic tumors and one was a primary tumor. Median sternotomy was performed in all patients to access the heart. Thrombi due to a cardiac mass were detected intraoperatively in some patients. Conclusion: Our study results suggest a high-degree of diagnostic confusion between intracardiac thrombi and tumors. Therefore, metastatic cardiac tumors should be considered in patients with pleural or pericardial effusion of no other identified cause
