Disfuncția tiroidiană la pacientul cu sindrom coronarian acut

Purpose. The study aims to determine the impact of dystyroidism on the type of acute coronary syndrome, on vascular function and coronary impairment, as well as on the myocardium and last but not least the general biological resonance of these hormones, emphasizing the role of thyroid hormones in the cardiovascular system. Methods. We introduced in the study 100 patients recently diagnosed with acute coronary syndrome, without history of ischemic heart disease or thyroid disease, hospitalized in the Cardiology Clinic of the Emergency Clinical Hospital Bagdasar-Arseni Bucharest, for the interventional treatment of acute coronary syndrome. The studied patients were hospitalized between November 2014 - April 2015, with follow-up up to 5 years, evaluated clinically, bio-humorally, by echocardiography, coronary angiography with SYNTAX score calculation and electrocardiogram and pulse wave. The obtained data were integrated in Excel sheets and statistically processed with the Python program. Results. The prevalence of dystyroidism in the study group was 44% (44 patients). Hypothyroidism is predominant (34 patients; 77%), and subclinical hypothyroidism occurs in 20 (59%) of subjects with hypothyroidism. Unstable angina is the predominant type of acute coronary syndrome, both in the whole group (54 patients; 54%) and in the group of patients with hyperthyroidism (7 patients; 70%), while acute myocardial infarction without ST-segment elevation was the type majority of presentation in patients with hypothyroidism (19 patients, 56%). Coronary heart disease varied as follows: in the total group unicoronary lesion (31 subjects; 31%), in patients with hyperthyroidism unicoronary lesion (5 subjects; 50%), in patients with hypothyroidism bicoronary lesion (10 subjects; 29%). And the calculated SYNTAX score is higher in the group of patients with dysthyroidism compared to the group of patients with euthyroidism. Discussions. Unstable angina (p = 0.006) and ventricular wall hypertrophy (p = 0.008) are predictive factors for dysthyroidism. Hypothyroidism correlates with high LDL-cholesterol levels (p = 0.0176) and hyposideremia (p = 0.0083), while hyperthyroidism correlates with thrombocytosis (p = 0.0122) and a significant nonspecific inflammatory syndrome (p = 0.0043). Dystyroidism has a direct correlation with the presence of kinetic disorders (Person correlation coefficient 0.21). Conclusion. Thyroid disease, with hypothyroidism or hyperthyroidism, can also be a risk factor for cardiovascular disease, and especially for ischemic heart disease.

Correlation of Motivation and Value Orientation of Project Managers

The objective of this paper is to identify the relationship between the dimensions of performance motivation and value preferences of project managers in large companies. To examine the relationship, it was first necessary to find out what the value system of project managers is and what their motivational profile is. The research took the form of a questionnaire survey in large Czech companies, which belong to CZ-NACE C. Standardized questionnaires were used for data collection. The PVQ questionnaire was used to determine the value system and the LMI questionnaire was used to determine the motivational profile. Data were evaluated by using descriptive statistics and relationships were evaluated by using Person's correlation coefficient. Student's t-test was used to verify statistical significance. It was found that the analyzed values in the set of respondents are almost the same, all analyzed values are perceived by the respondents as significant. The most represented value among the respondents is benevolence and the least represented is tradition. We identified identical findings in the case of analysis of performance motivation. Of the four dimensions of motivation examined, the project managers addressed confidence in success to be the most important. A statistically significant relationship was found between commitment and power and success, between flexibility and stimulation, universalism and benevolence, between self-control and power, success, conformity and safety, and between confidence in success and power, success and stimulation.

In this context, the IoT technologies acceptance by the future economists and managers is extremely important. The study included 1,179 students from four university centers from Romania and the included factors from the acceptance of IoT technologies model (Internet of Things) were analyzed using the quantitative statistical methods in SPSS, applying a series of tests processed to highlight the research results, respectively the reliability test, the validity test, the chi-square test and the Person's correlation coefficient. The results of the study show the existence of a positive correlation between the research variables and indicate that the students from the economic studies, are ready to accept the new technological advances in IoT and to implement them in their future jobs.

Sedentary Behaviour among Urban Civil Servants in Eastern Part of Southern Nations, Nationalities and Peoples' Region, Ethiopia.

Background Active lifestyle is a determining factor for functional and clinical health that protects and maintains both physical and mental health of an individual, whereas sedentary lifestyle is a contrary vital cause for higher premature mortality, heart disease, diabetics, and poorer quality of life. This study is aimed at determining the amount of time spent on sedentary activity and identifying sedentary behaviours frequently practiced by civil servants in Southern Ethiopia in 2015. Methods It was a cross-sectional study which employed both qualitative and quantitative approach. A stratified cluster sampling method was used to select 375 office workers (222 men and 153 women) from Hawassa, Wolayta Soddo, and Dilla ranging from 18-65 years old. Data were collected using harmonized self-reporting LASSA (Longitudinal Aging Study Amsterdam) questionnaires and prevalence estimates of mean sedentary time in each 12 activities per day were determined. Descriptive and inferential statistics such as Independent t-test, Uni-variate ANOVA, and Person's correlation were used to analyze association and predictability of IV on DV variables. Result The total mean time spent sitting per day was 13.39 h which was 81.5% of weak time. Collectively, screen time was dominant (6.08). About 70.7%, 23.7%, 4.8%, and 0.8% of respondents were levelled very high, high, moderate, and less sedentary, respectively. In general, women accounted higher sedentary level (96.1%) than men (93.3%) in sedentary activity. There is a weak positive correlation between age and time spent in an administrative task. Income and mealtime were statistically significant (r < 0.2, n = 375, p < 0.05). Conclusion The high level of self-reported sedentary time record suggests the need for public health policies targeted at increasing physical activity and decreasing sitting time through systemic intervention in and out of work.

Vertical distribution of Pu in forest soil in Qinghai-Tibet Plateau

The 239+240Pu and 137Cs activities and 240Pu/239Pu atom ratios in surface soil and soil core collected from Qinghai-Tibet Plateau were investigated. The maximum of 239+240Pu and 137Cs activity concentrations in five soil cores were found in upper layers and have a same trend: the maximum followed by exponential decline. The 240Pu/239Pu atom ratio ranged from 0.160 ± 0.009 to 0.212 ± 0.012, clarified that the plutonium mainly came from the global fallout and the contribution of Lop Nor test sites was negligible. In addition, the vertical profiles of radionuclides (210Pb, 238U, 232Th, 226Ra, 40K) have been studied and a high correlation has been found between them. The correlations of Pu between organic matter (OM) and heavy metals were also studied. Person Correlation Coefficients revealed Pu had significant positive correlations with organic matter and Cd, Cu, Co, Zn, but negative correlation with Tl. The results have important implication for further understanding of the sources, records and environmental impacts of global and regional nuclear activities, which expanded the database of Pu activity level and atom ratio in Chinese soil and established a foundation for future environmental risk assessment.

Conditions of enzyme-assisted extraction to increase the recovery of flavanone aglycones from pectin waste.

The citrus pectin by-product (CPB), generated from pectin industry, is a rich-source of flavanones, but not explored until now. As most of these compounds are inside vacuoles or bound to cell wall matrix, enzymatic hydrolysis was applied on their recovery, followed by hydroalcoholic and ultrasound extraction. Different parameters were studied: enzymes (β-glucosidase, tannase, and cellulase), their concentration (5, 10, and 20 U g-1 CPB), and reaction time (6, 12, and 24h). Extracts were characterized in total phenolic content (TPC), antioxidant capacity (ORAC and DPPH assays), and polyphenolic profile (HPLC-DAD). All enzymatic treatments significantly improved CPB antioxidant capacity and TPC, compared with hydroalcoholic and ultrasound extraction. β-glucosidase (5 U) for 24h was the most effective in polyphenol extraction and bioconversion, followed by β-glucosidase (5 U) for 12h and tannase (5 U) for 24h. Thus, the concentration of these enzymes was increased (10 and 20 U) to improve flavanones extraction. β-glucosidase at 20 U offered the highest amount of naringenin (77.63mg 100g-1 of CPB) and hesperetin (766.44mg 100g-1) obtained so far by biological processes. According to Person's correlation analysis, TPC and antioxidant activity were highly correlated with CPB contents of hesperetin and naringenin. The aglycone flavanones are rarely found in natural sources and have higher biological potential than their glycosylated forms. Our results indicated enzyme-assisted extraction as a good choice for recovering aglycone flavanones from CPB, and increased knowledge on the biological activity of this agroindustrial waste, amplifying their application in food and pharmaceutical field.

For the purpose of assessing the performance competency of the operating room nurses in Baghdad’shospitals, a descriptive study has been conducted from from 13th of December 2020 through 13 March 2020.The settings of the performed study were Al-Kindey hospital, Al-Yarmouk Hospital,, Baghdad teachinghospital in Baghdad city, For the study of (50) nurses who have been working definitely in the operatingroom in these hospitals, a purposeful sample has been selected.For the study purpose, a special tool has been developed which has been used for data collection. There arethree part compromising this tool which are dealing with performance of the nurse, demographic data, andaffordability of equipment and supplies in the operating room.A number of highly qualified experts have been asked to assess the validity of the questionnaire, where theyconfirmed its validity. As for the questionnaire’s legitimacy; it was specified according to the statisticallyacceptable person correlation coefficient of (r= 92).Data has been analyzed by using analysis of descriptive data (frequencies, percentages) and inferential dataanalysis (SPSS, 23).According to the conclusions that have been revealed by study, graduates from universities and institutes hadshowed a better practices performance than graduates from primary and secondary level.The study also indicate that scrub nurse practices in some domains were satisfactory (rehearsal of scrubnurses prior to actually entering OR, wearing operating clothes and gloves, draping and sheeting) andinadequate in some fields (practices concerned with surgical preparation, surgical hand scrub, antiseptic andtechnique and surgical instruments)).In the study between sexes, a non-significant variation illustrate years of experience in relation to the nurses’training sessions in OR.The investigation suggested that all nurses ought to circulate strategies to the staff concerning this issue;composed arrangements for the OR practice can be shared to the health-care providers for better execution,and supplies to hospitals such as antiseptic hand scrub strategies that inhibit pathogenic microorganismgrowth.

CircRNA TGFBR2/MiR-25-3p/TWIST1 axis regulates osteoblast differentiation of human aortic valve interstitial cells.

Calcified aortic valve disease (CAVD) is characterized by valve thickening and calcification. Osteoblast differentiation is one of the key steps of valve calcification. CircRNAs is involved in osteogenic differentiation of multiple mesenchymal cells. However, the function of circRNA TGFBR2 (TGFBR2) in CAVD remained unclear. We explored the effect and mechanism of TGFBR2 in modulating CAVD. Human aortic valve interstitial cells (VICs) were subjected to osteogenic induction, and transfected with TGFBR2, miR-25-3p mimic and siTWIST1. The relationship between miR-25-3p and GFBR2 was predicted by starBase and confirmed by luciferase reporter and Person's correlation test. The relationship between miR-25-3p and TWIST1 was predicted by TargetScan and confirmed by luciferase reporter assay. The expressions of TGFBR2, miR-25-3p, TWIST1, osteoblast markers (RUNX2 and OPN) were detected by Western blot or/and qRT-PCR. Alkaline phosphatase (ALP) activity and calcium nodule was determined by colorimetric method and Alizarin Red S staining. The expression of TGFBR2 was down-regulated and that of miR-25-3p was up-regulated in calcific valves and osteogenic VICs. TGFBR2 was inversely correlated with miR-25-3p expression in calcific valves. TGFBR2 sponged miR-25-3p to regulate TWIST1 expression in osteogenic VICs. During osteogenic differentiation, ALP activity, calcium nodule, the levels of osteoblast markers were increased in VICs. MiR-25-3p overexpression or TWIST1 knockdown reversed the inhibitory effect of TGFBR2 overexpression on ALP activity, calcium nodule, the expressions of RUNX2 and OPN in osteogenic VICs. The findings indicated that TGFBR2/miR-25-3p/TWIST1 axis regulates osteoblast differentiation in VICs, supporting the fact that TGFBR2 is a miRNA sponge in CAVD.

Factors determining different death rates because of the COVID-19 outbreak among countries.

BackgroundDuring the coronavirus disease 2019 (COVID-19) pandemic, all European countries were hit, but mortality rates were heterogenous. The aim of the current paper was to identify factors responsible for this heterogeneity.MethodsData concerning 40 countries were gathered, concerning demographics, vulnerability factors and characteristics of the national response. These variables were tested against the rate of deaths per million in each country. The statistical analysis included Person correlation coefficient and Forward Stepwise Linear Regression Analysis (FSLRA).ResultsThe FSLRA results suggested that ‘days since first national death for the implementation of ban of all public events’ was the only variable significantly contributing to the final model, explaining 44% of observed variability.DiscussionThe current study suggests that the crucial factor for the different death rates because of COVID-19 outbreak was the fast implementation of public events ban. This does not necessarily mean that the other measures were useless, especially since most countries implemented all of them as a ‘package’. However, it does imply that this is a possibility and focused research is needed to clarify it, and is in accord with a model of spreading where only a few superspreaders infect large numbers through prolonged exposure.

Evaluation of the phytoremediation uptake model for predicting heavy metals (Pb, Cd, and Zn) from the soil using Nerium oleander L.

The experiment was carried out during two seasons (spring and autumn) of the year 2015, in El-Max (industrial zone) and Antoniadis park (control zone), Alexandria, Egypt. Nerium oleander L. plants has been used in this experiment because of its capability to remediate heavy metals (HMs) from the soil. This study aimed to evaluate the performance of the Phytoremediation Uptake Model (UPM) in predicting the uptake of HMs (lead (Pb), cadmium (Cd), and zinc (Zn)) from the soil. UPM was used to estimate the contribution of various pathways in the remediation of these HMs through different parts, leaves, stem, and root. Besides, it includes soil-root-leaf and soil-leaf pathways and its deposition. The performance of the UPM has been examined using many statistical calculations tools (Person correlation coefficient (R2), root mean square error (RSME %), mean bias error (MB %), and Willmott index of agreement degree (d)). The results showed a high harmony between the UPM predictions and the experiment. Moreover, most R2 values are ranged mostly between 0.97 and 0.99 during the spring and the autumn in the study areas. Therefore, the correlation is very strong between the measured and the predicted HMs concentrations. In addition, the less value of RMSE% (0.13) was obtained in the lower parts of the plant, while the greatest value was observed in leaf model (42.53). Also, the values of MB% were acceptable and within the range between 3.01 and 10.41. In addition, the values of the Willmott index of the agreement were within the acceptable range (0.80 to 0.97). Thus, one may conclude that the UPM has proved a high performance in estimating the uptake and removal of different concentrations of HMs from soil under different spatial and temporal conditions.

PM2.5 source profiles from typical Chinese commercial cooking activities in northern China and its influences on bioreactivity of vascular smooth muscle cells (VSMCs)

Abstract Fine particulate matter (PM2.5) emitted from commercial cooking activities can lead cardiovascular diseases to humans. In this study, PM2.5 filter samples were collected from the exhausts of six typical and commercial cuisines including Sichuan cuisine, Shaanxi Cuisine, Northeast Chinese cuisine, Shaanxi snacks, hotpot and Chinese barbecue (BBQ) in the Northern China. Chemical components of carbonaceous fractions, water-soluble inorganic ions, elements, and polycyclic aromatic hydrocarbons [including parent PAHs (pPAHs), alkylated PAHs (aPAHs), oxygenated PAHs (oPAHs) and nitro PAHs (nPAHs)] were quantified. The bioreactivities in vascular smooth muscle cells (VSMCs) induced by the exposures to the PM2.5 were also measured. The PM2.5 concentration levels in the kitchen exhausts ranged from the lowest of 290 ± 104 μg m−3 for the Northeast Chinese cuisine to the highest of 3400 ± 978 μg m−3 for the Chinese BBQ. The PM2.5 composition was predominantly comprised of organic carbon (OC), especially for Sichuan and Shaanxi cuisines. The highest PAHs concentration was shown in the Chinese BBQ, followed by the stir-fry-dominated cuisines (i.e., Sichuan, Shaanxi and Northeast Chinese cuisines), and boiling-dominated cuisines (i.e., Shaanxi snacks and hotpot). The pPAH was the most dominated PAHs group. Our results demonstrated that higher cooking temperatures and larger oil consumptions could promote the PAHs formations. The levels of PM2.5 cytotoxicity for the examined cuisines showed a descending order of the Chinese BBQ > stir-fry-dominated cuisines > boiling-dominated cuisines. In addition, the Person's correlations demonstrated that the cooking emitted PM2.5 were much interrelated with the inflammation induction (R > 0.80) than the oxidative stress (R > 0.60) due to the toxic chemical compositions. Using the stepwise regression model, the bioreactivities in VSMCs were found to be conquered by the concentration levels of 12 key chemical components such as chromium (Cr) and 9-methylanthracene. The regression formula explained nearly 100% of the variations on the induced bioreactivities (R2 = 1.00), suggesting that the suppression of emissions of Cr (or 9-methylanthracene) could be efficient in reducing the cytotoxicity induced by cooking emitted PM2.5.

Prediction of soil loss due to erosion using support vector machine model

Soil erosion refers to the detachment and removal of soil particles from land (topsoil), by the natural physical forces (water, glacier and wind). Soil erosion causes soil loss in the catchment or any land areas severely impacting agriculture activity, sedimentation in the dam reservoirs, and hampering developmental activities. Therefore, it is desirable to accurately measure soil loss due to erosion for the development and management of an area. With this objective, a well-known machine learning algorithm Support Vector Machine (SVM) has been used in the development of the soil loss prediction model. Eight erosion affecting variable inputs: ambient temperature Tair, rainfall, Antecedent Moisture Conditions (AMC), rainfall intensity, slope, vegetation cover, soil temperature Tsoil and moisture of the soil. Data on published literature was used in the model study. The accuracy of the proposed SVM was assessed by using three statistical performance evaluation indicators namely Person correlation coefficient (R), Root Mean Squared Error (RMSE), Mean Squared Error (MAE). Partial Dependence Plots (PDP) was used to investigate the dependence of prediction results of eight input variables used in the model study. Model validation results showed that SVM model performed well for the prediction of soil loss for testing (R = 0.8993) and also for training (R=0.9123). Rainfall intensity and vegetation cover were found to be the two most important affecting input parameters for the soil loss prediction.
