Evaluating the psychometric properties of a scale to measure intercultural effectiveness

The aim of this research is to examine the validity and reliability of the Turkish version of The Intercultural Effectiveness Scale (IES; Portalla & Chen, 2010). The sample of this study consisted of 352 (199 female and 153 male) students. The results of confirmatory factor analysis demonstrated that the 20 items loaded on five factors and the five-dimensional model was well fit (x²= 370.10, df= 152 p= .00, RMSEA= .064, NNFI= .94, CFI= .95, IFI= .95, NFI= .92, RFI= .90, GFI= .91 and SRMR=.066). The overall internal consistency coefficient of the scale was .83. The corrected item-total correlations of IES ranged from .27 to .68. Overall findings demonstrated that this scale had high validity and reliability scores. Nevertheless, further studies that will use IES are important for its measurement force

The relationship of economic growth and carbon-dioxide emissions: an application on member countries of Organization of Islamic Cooperation

Motivation: Humanity has benefited from natural resources in production activities throughout history and this pressure on natural resources has increased even more with the efforts of industrialization. In this process, people benefited heavily from fossil fuels in their production and distribution activities, thereby damaging the environment and the atmosphere to a large extent. With the destruction of the environment, it has become important for the countries and the academic circles to measure environmental damage with the increase of economic activities in order to take various measures. Aim: At this point, in this study, the relationship between economic growth and carbon-dioxide emissions was examined within the scope of 50 countries that are members of the Organization of Islamic Cooperation (OIC). In this process, annual data of the countries concerned between 1995 and 2017 were used; Pedroni Cointegration Analysis, Granger Causality Analysis, Pooled Mean Group Estimator (PMGE) and Mean Group Estimator (MGE) methods were used to measure and estimate the relationship between these two variables. The causality analysis shows that the economic growth is the Granger cause of carbon-dioxide emissions in the country group studied. In addition, the coefficients obtained in PMGE and MGE analyzes were found as 0.43 and 0.33 and were statistically significant and positive. Then, with the help of Hausman Homogeneity Test, it was decided between the two estimators, and it concluded that PMGE Estimator is the more reliable estimator. Results: The results obtained with the PMGE estimator indicate that the 1% increase in economic growth increased carbon dioxide emission by 0.43%

Je li fleksibilna bronhoskopija siguran postupak kod kritičnih bolesnika s respiracijskim zatajanjem?

Flexible bronchoscopy (FB) plays an important role in critical care patients. But, critical care patients with respiratory failure are at an increased risk of developing complications. Considering the developments in intensive care unit care in recent years, we aimed to evaluate the use of FB in these patients. We retrospectively reviewed patients who underwent FB in critical care between 2014 and 2020. A total of 143 patients underwent FB during the study period. Arterial blood gas measurement on the FB day revealed a mean PaO2/FiO2 of 186.94±28.47. Eighty-one (56.6%) patients underwent an fiberoptic bronchoscopy procedure under conventional oxygen supplementation, 10 (7%) on noninvasive ventilation, 13 (9.1%) on high flow nasal cannula, and 39 (27.3%) on invasive mechanical ventilation. During and immediately after bronchoscopy, none of the patients experienced life-threatening complications. Fifty-five (38.5%) patients developed complications that could be controlled. Multivariate analysis indicated that increased Apache-II score and presence of cardiovascular disease were significantly associated with an increased complication risk. Although critical care patients with respiratory failure are more prone to complications, diagnostic and therapeutic bronchoscopy may be performed following appropriate patient selection, without leading to major complications.Fleksibilna bronhoskopija (FB) igra važnu ulogu u bolesnika na kritičnoj skrbi. Međutim, ovi bolesnici na kritičnoj skrbi s respiracijskim zatajenjem imaju povećani rizik od razvoja komplikacija. S obzirom na napredak u skrbi u jedinici intenzivnog liječenja tijekom posljednjih godina cilj je bio procijeniti uporabu FB-a u ovih bolesnika. Retrospektivno smo pregledali podatke bolesnika koji su podvrgnuti FB-u u kritičnoj skrbi između 2014. i 2020. godine. Ukupno je 143 bolesnika podvrgnuto FB-u tijekom razdoblja ispitivanja. Mjerenje plinova u arterijskoj krvi na dan FB pokazalo je srednju vrijednost PaO2/ FiO2 od 186,94±28,47. Osamdeset jedan bolesnik (56,6%) podvrgnut je postupku fiberoptičke bronhoskopije pod konvencionalnim dodacima kisika, 10 (7%) na neinvazivnoj ventilaciji, 13 (9,1%) na nosnoj kanili s velikim protokom i 39 (27,3%) na invazivnoj mehaničkoj ventilaciji. Tijekom i neposredno nakon bronhoskopije niti jedan bolesnik nije doživio komplikacije opasne za život. Osim toga, 55 (38,5%) bolesnika razvilo je komplikacije koje se mogu kontrolirati. Prema multivarijatnoj analizi, povećani rezultat Apache-II i prisutnost kardiovaskularnih bolesti bili su značajno povezani s povećanim rizikom od komplikacija. Iako su bolesnici na kritičnoj skrbi s respiracijskim zatajenjem skloniji komplikacijama, dijagnostička i terapijska bronhoskopija mogu se provesti nakon odgovarajućeg odabira bolesnika, a da to ne dovede do većih komplikacija

The Effects of Aerobic and Anaerobic Training Programs Applied to Elite Wrestlers on Body Mass Index (BMI) and Blood Lipids

The purpose of this study is to analyse the effects of aerobic and anaerobic training programs applied to elite wrestlers on body mass index (BMI) and blood lipids. 20 elite wrestlers, whose average age is (experimental group; 15.20±4.61, n=10), control group; 15.90±2.08, n=10), participated in the study and they were randomly divided into two groups. Strength and endurance training programme based on “one day aerobic, one day anaerobic” principles was applied to the experimental group six days a week for eight weeks. The control group went on doing normal routine wrestling technical training. Before and after eight-week training program, BMI, Triglyceride, HDL-C, VLDL, Cholesterol, LDL blood values were taken from the experimental and the control group by body analyser. According to the results of the study, none of the blood lipid indicators of the control group did significantly changed from pretest to posttest. (p>0.05). However, HDL-C, cholesterol and LDL values from blood lipids indicators of the experimental group changed significantly from pretest to posttest. (p<0.05). There were no significant changes in body mass index (BMI), Triglyceride and VLDL. As a result, this study revealed that there was no significant difference in the control group which did exercise routinely, while the training programme with changeable type and volume made significant differences in the experimental group.In statistical analyses, paired- samples t test was used for intra-group comparisons, and independent sample t test was used for inter-group comparisons. The significance level was determined as p<0.05. For all the values, mean and standard deviation were used

The Effects of Separate and Combined Use of PGF2α and GnRH Hormones and the Addition of Βeta-Carotene on Fertility Parameters in Dairy Cows with Ovarian Cysts

Background: Ovarian cysts are commonly observed pathologies, which interfere with normal cyclic activity and adversely affect fertility in cows. Beta-carotene is effective in the reduction of reproductive problems by inducing the natural defence mechanisms of the body. There are several methods that can be used for the treatment of ovarian cysts. The separate and combined use of GnRH and PGF2α commonly uses in the treatment of ovarian cysts. Therefore, in the presented study the effects of Beta-carotene (βC) addition for the treatment of ovarian cysts either with GnRH solely or GnRH and PGF2α in combination on the fertility parameters of dairy cows were investigated.Materials, Methods &amp; Results: Seventy-six Holstein Friesian cows having ovarian cysts diagnosed by ultrasonography (USG) were divided into three groups. Cows in Group I (GI, n = 27), were injected with GnRH (Buserelin acetate, 5 mL, im), PGF2α (Tiaprost-trometamol, 5 mL, im) and βC (20 mL/cow, into 4 regions by im route). In Group II (GII, n = 25) GnRH (Buserelin acetate, 5 mL, im) and PGF2α (Tiaprost-trometamol, 5mL, im) were administrated while GnRH (Buserelin acetate, 5 mL, im) solely in Group III (GIII, n = 24). Cysts were monitored via USG, and blood samples were collected on the on day of treatment (day 0) and on the 7th and 14th days following the administrations. Cows shoving oestrous were inseminated and pregnancy diagnoses were performed on the 40th day following insemination. Treatment results showed that there were statistically no significant differences between GI and GII (P &gt; 0.05). Only numerical difference obtained in time from therapy to pregnancy and overall pregnancy index (P &gt; 0.05). Overall pregnancy rate (85 %), first service pregnancy rates (40 %) and overall pregnancy index (2.11) in GI were found significantly higher than GIII (53.3 %; 20 %; 4.12) [P &lt; 0.05]. No significant difference was observed in progesterone (P4) levels between the groups (P &gt; 0.05). It was found that βC administrations significantly increased βC levels in GI than GII and GIII on the 7th and 14th days (P &lt; 0.05).Discussion: One of the most common problems encountered in modern dairy production is the development of ovarian cysts. Treatments for ovarian cyst are numerous and variable, and have changed considerably over the years. In the present study, GnRH and PGF2α were administered together as a combination, and as a result of this combined use, higher percentages were obtained for both pregnancy rate and fertility parameters in GI and GII, in comparison to the group administered with GnRH alone (GIII). Better outcome from combination therapy (GnRH and PGF2α) may be due to the fact that luteal thickening in the walls of cysts was determined by ultrasonography, but P4 values were not identified immediately and the treatments were not categorized in accord with these values. No statistically significant differences were determined between GI and GII concerning the fertility parameters investigated, however numerical and proportional differences were observed. βC levels were significantly higher on day 7 and 14 after treatment in GI which were administered βC additionally to the treatment protocol for ovarian cysts. This statistical difference suggests that administration of βC in combination therapy is also effective in the treatment of ovarian cysts. In conclusion, it was determined that high pregnancy rates were obtained by the combined treatment of ovarian cysts (GnRH + PGF2α) and number of inseminations per conception were at desired limits. Better percentile and numerical fertility parameters were achieved in the group, which additionally received βC, high numbers of infertility cases, βC supplementation could be a viable option for treatment

Post COVID-19 irritable bowel syndrome

Objectives: The long-term consequences of COVID-19 infection on the gastrointestinal tract remain unclear. Here, we aimed to evaluate the prevalence of gastrointestinal symptoms and post-COVID-19 disorders of gut-brain interaction after hospitalisation for SARS-CoV-2 infection. Design: GI-COVID-19 is a prospective, multicentre, controlled study. Patients with and without COVID-19 diagnosis were evaluated on hospital admission and after 1, 6 and 12 months post hospitalisation. Gastrointestinal symptoms, anxiety and depression were assessed using validated questionnaires. Results: The study included 2183 hospitalised patients. The primary analysis included a total of 883 patients (614 patients with COVID-19 and 269 controls) due to the exclusion of patients with pre-existing gastrointestinal symptoms and/or surgery. At enrolment, gastrointestinal symptoms were more frequent among patients with COVID-19 than in the control group (59.3% vs 39.7%, p&lt;0.001). At the 12-month follow-up, constipation and hard stools were significantly more prevalent in controls than in patients with COVID-19 (16% vs 9.6%, p=0.019 and 17.7% vs 10.9%, p=0.011, respectively). Compared with controls, patients with COVID-19 reported higher rates of irritable bowel syndrome (IBS) according to Rome IV criteria: 0.5% versus 3.2%, p=0.045. Factors significantly associated with IBS diagnosis included history of allergies, chronic intake of proton pump inhibitors and presence of dyspnoea. At the 6-month follow-up, the rate of patients with COVID-19 fulfilling the criteria for depression was higher than among controls. Conclusion: Compared with controls, hospitalised patients with COVID-19 had fewer problems of constipation and hard stools at 12 months after acute infection. Patients with COVID-19 had significantly higher rates of IBS than controls. Trial registration number: NCT04691895
