Published: April 2021

Aim: The progesterone’s optimal route for luteal phase support (LPS) in frozen-thawed embryo transfer (FET) cycles is controversial. This study investigates the effect of three treatment regimens of progesterone: vaginal, oral, and subcutaneous form for LPS in FET cycles.

Material and Method: Blastocyst cryopreserved FET cycles utilizing vaginal, subcutaneous, or oral forms of progesterone between December 2018 and May 2020 were included. The main outcome was to compare clinical pregnancy rates (CPR), ongoing pregnancy rates (OPR), and live birth rates (LBR) in different progesterone groups.

Results: A total of 434 cycles were included, of which 200 utilized vaginal, 124 utilized subcutaneous, and 110 utilized oral forms. Demographic and cycle characteristics were similar between all three groups. Compared to cycles utilizing vaginal, subcutaneous, and oral forms, CPR, OPR, and LBR differ significantly between the three groups (p-value = 0.000). Miscarriage was calculated according to the number of days after embryo transfer, and it was shown that the subcutaneous group had the lowest rate of miscarriage with 11 cases (8.8%). The highest OPR was associated with the subcutaneous group with 67 (54%), followed by the vaginal group with 92 (46%). The highest LBR was in the subcutaneous group, with 59 (47.6%) cases. The oral group was significantly less successful 29 ( 26.4%) than the subcutaneous and vaginal groups.

Conclusion: Our study results showed that subcutaneous and vaginal progesterone performed better than oral progesterone for LPS in patients undergoing FET. All three forms of progesterone administration were safe and well-tolerated.

Objective: Demographic and laboratory values predicting clinical severity in Covid-19 patients have been a matter of curiosity since the beginning of the disease. We aimed to show the relationship between the severity of Covid-19 disease and comorbidities, clinical and laboratory features of the patients.

Material and Methods: The data of Covid-19 patients diagnosed with polymerase chain reaction (PCR), were analyzed retrospectively. The patients were divided into 3 groups according to their clinical severity as mild, moderate and severe. Comorbidities and the Charlson Comorbidity Index (CCI) at the time of diagnosis were calculated for each patient from the patients' records. Demographic data, laboratory values, comorbidity and CCI scores were compared between the patient groups. The effect of CCI on survival and length of hospital stay was examined.

Results: One hundred and four patients were included in the trial. The most common comorbid disease in the patients included in the trial was hypertension. The moderate-severe stage patients were statistically significantly older (p
Antibiotic resistance pattern in Shigella species isolated from children with acute diarrhea in Tabriz city, Iran
Authors: JAFARI-SALES Abolfazl , SHARİAT Afsoon
Published: April 2021

Background and aim: Shigella is one of the leading causes of acute diarrhea in children worldwide. Antibiotic resistance in this bacterium has increased due to the indiscriminate use of common antibiotics. Therefore, the aim of this study was to investigate the prevalence and pattern of antibiotic resistance in Shigella species isolated from children with acute diarrhea in Tabriz hospitals.

Materials and methods: In this descriptive cross-sectional study, 321 samples suspected of Shigella were collected from children's diarrhea stool samples and identified using standard microbiological and biochemical tests. Antibiotic resistance was also determined using disk diffusion by the Kirby-Bauer method.

Results: A total of 84 samples were positive for Shigella. Among them, S. flexneri species with 83.3% had the highest frequency and S. boydii with 13.1%, S. sonnei with 2.4% and S. dysanteriae with 1.2% had the lowest frequency. The highest resistance was related to the antibiotics cotrimoxazole (92.85%), tetracycline and ampicillin (67.86%) and the lowest resistance was related to imipenem antibiotics (2.38%) and ceftizoxime (9.52%).

Conclusion: The present study showed that Shigella flexneri is the predominant species isolated from children with Shigellosis in hospitals in Tabriz city. Our results also indicate an increase in resistance to common antibiotics. Therefore, it is recommended that antimicrobial susceptibility testing be performed in the study area prior to antibiotic administration.

Authors: ARICAN Burçin , ATAV ATEŞ Ayfer
Published: April 2021

Aim: The purpose of this study was to evaluate and compare the cyclic fatigue resistance of two different single file nickel-titanium instruments -Reciproc blue (RB) and One Curve (OC)- used for single or in a certain number of times. Material and Methods: One Curve (n=40) and Reciproc Blue (n=40) files were used in this study. The instruments were divided into two subgroups (n=20); those to be used for the first time(N) and those that were previously used (U) in the clinic for the root canal treatment of a vital mandibular molar with three root canals. Cyclic fatigue testing of these instruments was performed in an artificial stainless-steel canal with 60° curvature, 5 mm radius 1.5 mm width, and 3.0 mm depth. All the tested files were rotated/reciprocated under the continuous irrigation with distilled water at 37°C until fracture occurred. The time to failure (TTF) in seconds and the number of cycles to failure (NCF) were recorded. Data were statistically analyzed and the significance level was set at P < 0.05. Results: A significant difference was observed among the four groups and between RB-N/RB-U, OC-N/OC-U, RB-N/OC-N, and RB-U/OC-U, regarding TTF and NCF values (P < 0.05). Predicted time for % 99 survival were RB-N >RB-U > OC-N > OC-U. The TTF value of RB is greater than OC in both the new instrument groups and the used instrument groups. Conclusions: RB showed higher cyclic fatigue resistance than OC files in both new and used instrument groups. Reuse of RB and OC instruments significantly reduced the cyclic fatigue resistance of the instrument.
The effect of normotensive arterial pressure on cerebral saturation during carotid endarterectomy
Authors: YÜCEL Cihan , KAYALAR Nihan
Published: April 2021

Aim: Monitoring of cerebral perfusion during carotid endarterectomy helps to institute early intervention to prevent risk of ischemia during the operation.

We aimed to evaluate if the disadvantages of high systemic pressure can be avoided by keeping arterial blood pressure below 150mmHg during cross-clamping of the internal carotid artery by correlating our findings of NIRS values with clinical results

Material and Method: This was designed as a prospective study that included elective patients scheduled for an operation of carotid artery stenosis under general anesthesia. A total of 60 patients operated on between August and October 2019 were included in the study.

Results: Patients' NIRS findings on the right and left hemispheres were analyzed separately to be able to differentiate any possible changes of NIRS of the cerebral hemisphere ipsilateral to the clamped carotid artery. The analysis of the right and left NIRS findings in these 60 patients revealed a significant decrease between intubation and incision NIRS values (p=0.008 and p= 0.02respectively).

Conclusion: Considering the NIRS findings and clinical observations of the patients in the postoperative period, we think that ICA endarterectomy operations may be safe to perform in a suitable patient group while the systolic arterial blood pressure is maintained below 150mmHg during cross-clamping.

Published: April 2021

Careful design of study plan is a key element of any successful educational program. Till 2018 Ministry of Health of Ukraine regulated the structure of Pharmacy study plans through the adoption of unified Ministerial study plan. Now the responsibility of educational programs and corre- sponding study plans design in Ukraine is fully transferred to universities. The purpose of this study is to compare the structure and content of pharmacy study plans in Visegrad Group countries with the most recent unified Pharmacy study plan in Ukraine. Methods. The official documents of Warsaw Medical University, Jagiellonian University in Krakow, Charles University, University of Veterinary and Pharmaceutical Sciences Brno, Comenius University, University of Veterinary Medicine and Pharmacy in Kosice, Semmelweis University and University of Debrecen were studied and data on required courses and corresponding ECTS credits extracted and compared with Ukrainian study plan. Results. Ukrainian unified study plan in Pharmacy pays much more attention to Humanity, Social and Economics section (9 ECTS credits plus 6 ECTS credits of Foreign Language), Computer and IT skills (8 ECTS credits), Hygiene and Ecology (3 ECTS credits), Life Safety, Labor Safety and Bioethics (6 ECTS credits in total), Extreme Medicine and Military Training (6 ECTS credits in total), Toxicological and Forensic Chemistry (4 ECTS credits), Organization and Economics of Pharma- cy, Pharmaceutical Management and Marketing (12 ECTS credits in total) as compared to foreign universities. While natural science courses receive less ECTS credits in Ukraine, and some courses in rapidly evolving sciences like Molecular Biology, Immunology or Clinical Biochemistry are sig- nificantly underrepresented. Conclusions. The Pharmacy study plans of Visegrad Group universities show greater similarity with each other and tend to differ from the Ukrainian Ministerial study plan. The necessary steps to harmonize Pharmacy study plans of Ukrainian universities with V4 coun- tries include the introduction of Molecular Biology, Immunology, Clinical Biochemistry courses, and strengthening the basic medical and chemical science courses like Human Anatomy and Physiology, Organic Chemistry, Analytical Chemistry, Pharmacology, Medicinal and Pharmaceutical Chemistry.

Published: April 2021

The comorbid course of liver cirrhosis and atrial fibrillation causes higher levels of hospitalizations, mortality and ischemic stroke. According to current data, hemostasis in patients with liver cirrhosis is in a rebalanced dynamic state, but there are no data on the effect of atrial fibrillation on the hemostasis in patients with liver cirrhosis. Aims of the study. To assess abnormalities in primary, secondary haemostasis and fibrinolytic system in patients with liver cirrhosis and atrial fibrillation by using standard laboratory coagulation parameters and to investigate their changes depending on the stage of liver cirrhosis A, B, C according to Child-Pugh score. Materials and methods. A cross-sectional prospective study was conducted with the inclusion of 106 patients aged 42 to 83 years: group I (n = 70) - with liver cirrhosis and atrial fibrillation, II (n = 36) - with liver cirrhosis, which were distributed depending on the Child- Pugh score stages of cirrhosis and 20 healthy individuals. The levels of platelets, activated partial thromboplastin time, international normalized ratio, prothrombin time, thrombin time, fibrinogen, D-dimer were assessed on a Steellex M200 coagulometer. Statistical analysis (IBM SPSS Statistics) was performed. Results. The level of platelets in patients of group I was reduced by 37.4% (200 ± 8.33 vs. 274.7 ± 3.4; p,000.001), an activated partial thromboplastin time was prolonged by 38.6% (44.35 ± 1.39 vs. 32.01 ± 0.63, p˂0.001), prothrombin time was prolonged by 73.5% (19.4 ± 0.87 vs. 11.18 ± 0.53, p˂0.001), thrombin time was prolonged by 2.07 (25,7 ± 1.31 vs. 12.4 ± 0.66, p˂0.001), the international normalized ratio was increased by 24.3% (1.38 ± 0.04 vs.1.11 ± 0.01, p˂0.001) compared to control. The fibrinogen level was 20.9% higher (4.17 ± 0.17 vs. 3.45 ± 0.11, p˂0.001)

than in control group and was 83.7% higher (4.17 ± 0.17 vs. 2.27 ± 0.13, p˂0.001) than in group II. The D-dimer level was 83% higher than in control (675 ± 22.3 vs. 368.8 ± 21.85, p˂0.001) and 44% higher (675 ± 22.3 vs. 469 ± 37.18, p ˂0.001) compared with group II. Conclusions. In patients with liver cirrhosis and atrial fibrillation abnormalities of primary hemostasis are detected due to decrease of platelets on the background of portal hypertension. At the secondary stage of hemostasis indicators of external and internal coagulation mechanisms are prolonged due to the reduced synthesis of coagulation factors by the liver. Increased level of fibrinogen is determined at the stage of compensated and subcompensated cirrhosis with a gradual decrease at the stage of decompensation. The high activity of the fibrinolytic system is observed due to increase in the D-dimer levels, which may indicate a prothrombotic state in these patients.

Published: April 2021

The problem of studying the mechanisms of the occurrence of traumatic brain injury remains a very urgent issue for forensic medicine. The high incidence and high mortality rate of head injuries underlines its importance to experts. The article presents a case from the prac- tice of a forensic medical examination of a trau- matic brain injury. This case is indicative, since it clearly demonstrates the difficulties that forensic doctors face when examining craniocerebral inju- ries, when determining the mechanism of damage and the severity of bodily injuries. In this case, there is damage to the head and a concussion. The cited several conclusions of the experts of the bureau of forensic medical examination and the commission examination of the Main Bureau of Forensic Medical Examination of the Ministry of Health of Ukraine regarding the forensic medical assessment in the case of traumatic brain injury with damage to the head. When conducting an investigative experiment, it was determined that the simultaneous occurrence of an abrasion and a concussion of the brain with one traumatic effect in the glabellar region is unlikely. After all, a con- cussion of the brain and abrasions in the glabellar area were formed by different mechanisms. The results of this assessment of the characteristics of traumatic brain injury can be useful for prevent- ing difficulties in establishing the mechanism of damage in further expert practice.
ANALYSIS OF COMPLICATIONS INDUCED BY IODINE-BASED RADIOGRAPHIC CONTRAST MEDIA AND OF METHODS OF THEIR PREVENTION (A literature review)
Authors: Kolotova Liudmyla , Romanenko Hanna , Tkachenko Michael
Published: April 2021

The existence of modern medical practice is impossible without the use of radiological diagnostic methods. Due to the introduction of evidence-based medicine, most diagnoses need to be confirmed by imaging techniques, and some diseases require radiographic contrast media. Despite the medical and scientific break- through in these technologies, there are still risks of developing an individual body reaction to the contrast agent. In view of this, the purpose of the work was to substantiate the choice of iodine-containing radiographic contrast agents, to study the possible complications caused by these substances during the X-ray examination, and the methods of prevention of such conditions. To determine these key points, an analytical review of the literature was conducted. Analysis of iodine-containing radiographic contrast agents, which differ in their chemical structure and prop- erties, showed the advantage of non-ionic radiographic contrast media over the ionized ones. The work considers hypersensitive reactions and thyroid dysfunctions caused by the introduction of iodine-containing contrast agents. The allergic reactions may occur occur regardless of the dose of the drug, immediately or after some time after the examination. Due to the fact that the average duration of radiographic examination is from a few minutes to an hour, the appearance a certain reaction to iodine-containing radiographic contrast agents in a patient may not be established in time. That is why, it important to monitor a patient in the radiology department for 30 minutes after the examination. When establishing an increased risk of hypersensitivity reactions, due to the collection of anamnesis, it is necessary to carry out premedication with glucocorticoids is recommended according to the scheme that is described in the literature and is used in the modern medical practice. The development of hyperthyroidism or hypothyroidism depends on the initial level of hormones and the correct operation of the response system. In the presence of anamnestic and laboratory risk factors that can cause the occurrence of these conditions (TSH, free T4, total T3 and Thyroid peroxidase antibodies), it is recommended to consult an endocrinologist and, based on his/her judgement, to carry out premedication with the control of the TSH levels according to the schemes presented in the literature review or, alternatively, to correct the existing pathological conditions before the examination.
Contributing factors for the underutilization of mobility stations: the case of the "wien mobil station" in vienna
Authors: Silva Luiza Maciel Costa da , Uhlmann Julius
Published: April 2021

Purpose: Mobility stations are locations in which various mobility options are offered enabling multimodality and intermodality. In Vienna, three public mobility stations were implemented as part of the project “Wien Mobil”. After observing the existing mobility stations and talking to different experts, the system was diagnosed as underutilized. Consequently, this paper aims to point out the reasons why the public mobility stations in Vienna have so far not attracted as many users as expected.

Methodology/Approach: The research question is answered with the support of explorative expert interviews, observational research and literature review.

Findings: The identified contributing factors for the underutilization of the mobility stations in Vienna are location, weather, lack of interoperability, low affordability, lack of reliability, and lack of publicity and educational campaigns.

Research Limitation/implication: The research lacks the perspective and data from the car sharing provider. Moreover, it was conducted during winter, which certainly increased the perception of an underutilized system.

Originality/Value of paper: This work is expected to contribute to urban mobility planning by identifying and reaffirming important factors to take into account when planning, implementing and operating mobility stations and by providing a thorough understanding of the reasons for the underutilization of mobility stations.
The Road to Nicopolis, Part 1.
Authors: Kranzieritz Károly
Published: April 2021

In the past decades, or even during the last hundred years, many books and articles have been published on the Crusade in 1396 and on the Battle of Nicopolis. The interest is not surprising, because this was one of the iconic late medieval crusader events. Serious preparations were taken. This includes the parade as well. The theme is huge, so the study is going to deal only with Hungary and the western section of the route of the Hungarian troops. The deployment route of the marching battalions/armies is far from being as clarified as one might think. My study attempts to answer the following questions: When did the Western crusaders reach Buda, and when and on what route did they proceed south? When did the Hungarian king and his barons – and with them the Hungarian troops – join the crusaders? How many columns were involved in the advancement? The study shows that Sigismund, after receiving in Buda the Western leaders, made an important diplomatic detour to the Hungarian-Polish border. The arrival of Western leaders to Buda should be placed on the first half of June. After that the study will take into account the possible routes of the Western and Hungarian Crusaders. Another part of the crusader army was the minor army columns which advanced through Transylvania to Wallachia and were led by the faithful baron of the Hungarian king, Voivode Stibor.

Jelen tanulmány az NKE ÁNTK szervezésében 2019. november 29-én „A kihágásokról szóló büntetőtörvénykönyv az 1879. évi XL. törvénycikk elfogadásának 140. évfordulója alkalmából” címmel megrendezett konferencián elhangzott referátum átdolgozott, szerkesztett változata. A tanulmány az összehasonlító jogtörténeti módszerrel vizsgálja a Csemegi Károly által szerkesztett magyar kihágási törvénykönyv európai modelljeit. Vizsgálatai során az 1810-es francia Code Pénal, az 1867-es belga Büntető törvénykönyv és az 1871. évi német Btk. kihágásokat tartalmazó részeinek elemzésére és a magyar szabályozással való összevetésre fókuszál. A szerző megállapítja, hogy a magyar Kbtk. ugyan figyelembe vette az európai mintákat, de egyiket sem követte szolgai módon. A kihágások anyagi jogát európai színvonalon szabályozta ugyan, de az eljárások hatékony lefolytatásához szükséges szervezeti változtatások nem történtek meg, így nem jött létre a francia és a belga mintának megfelelően működő egységes és általános kihágási bíróság, ezáltal az eljárások anyagi és személyi feltételei sem lettek kielégítően biztosítva.
Fan Involvement and Unusual Investor Behavior: Evidence from a Football Fan Bond
Authors: Weimar Daniel , Fox Alexander
Published: April 2021

Abstract: Sport clubs offer marginal substitutable services and thus achieve strong emotional ties with their customers and fans. If sport clubs need financial support from their fans via a bond, the behavior of these investors might differ from that of less tied-in bond investors. The degree of fan involvement might be a decisive factor. Therefore, we use survey data obtained during a football club bond issue. We find correlations suggesting that fan bond investors with a higher fan involvement have a higher probability of investing as well as a greater tendency toward unusual investment behavior. The results are of relevance to sport managers when planning the issue of a bond.
Corruption and Sponsor Value: An Event Study Analysis
Authors: Chakravarti Pritha , Boronczyk Felix
Published: April 2021

Abstract: This study quantifies the negative effects of corruption on sponsors of the Indian Premier League (IPL) and presents unbiased sponsor-linked outcomes as its results. The event study methodology was used for the purpose of measuring the reaction of the Indian shareholders to the unexpected event that was the decision of the Supreme Court of India to ban two teams and several officials from cricketing affairs for life in response to the discovery of corruption. The results of this study show there is an immediate loss in firm value for sponsors that are linked to events and teams proved to be corrupt. The negative effects are larger for firms that are event sponsors, as compared to team sponsors. Some sponsors of non-corrupt teams also suffered damage due to the announcement of the Court; however, this effect was short-lived and wore off relatively quickly.

Published: April 2021

Oil palm empty fruit bunch (EFB) biomass is a potential source of renewable energy. Catalytic fast-pyrolysis batch process was initially performed to convert oil palm EFB into bio-oil, followed by its refinement to jet bio-fuel. Crystalline zeolites A and Y; synthesised from rice husk ash (RHA), were applied as heterogeneous catalysts. The catalytic conversion of oil palm EFB to bio-oil was conducted at a temperature range of 320-400°C with zeolite A catalyst loadings of 0.6 - 3.0 wt%. The zeolite catalysts were characterised by XRD, FTIR and FESEM. The bio-oil and jet bio-fuel products were analysed using GC-MS and FTIR. The batch fast-pyrolysis reaction was optimised at 400°C with a catalyst loading of 1.0 wt%, produced 42.7 wt% yields of liquid bio-oil, 35.4 wt% char and 21.9 wt% gaseous products. Analysis by GCMS indicates the compound distribution of the liquid bio-oil are as follows: hydrocarbons (23%), phenols (61%), carboxylic acids (0.7%), ketones (2.7%), FAME (7.7%) and alcohols (0.8%). Further refinement of the liquid bio-oil by catalytic hydrocracking over zeolite Y produced jet bio-fuel, which contains 63% hydrocarbon compounds (C8-C18) and 16% of phenolic compounds.

Published: April 2021

Fuels combustion, polluting the atmosphere is a side effect of an engines’ work. ncreasing ecological awareness has led to constant pursuit of disposing harmful substances properly. Catalytic converters (car catalysts), containing precious metals from the platinum group, including palladium, platinum and rhodium, have been commonly adopted for this purpose. These critical elements can be found in many raw materials used frequently throughout the economy. Therefore, it is economically viable to retrieve these elements from, among the others, spent catalysts, so they can be reused to manufacture new converters. In order to determine a possible cost of spent car catalyst, it is essential to use the analytical techniques to determine elemental content in any given sample. X-ray fluorescence spectroscopy (XRF) is an example of such a technique. It is nevertheless advisable to use a complementary procedure to confirm any results obtained. A cross-verification technique was developed using inductively coupled plasma mass pectrometry (ICP-MS). This procedure was verified using comparative studies, which confirmed its usefulness and correctness.
The Right to the City and to the University: Forging Solidarity Beyond the Town/Gown Divide
Authors: Ferman Barbara , Greenberg Miriam , Lee Thao , McKay Steven C.
Published: April 2021

Over the last fifty years, institutions of higher education have served as anchor institutions in cities’ broader neoliberal efforts to generate new economic sectors, attract the creative class, and build amenities that stimulate market-oriented redevelopment. These activities, combined with universities’ own neoliberal restructuring, including diminishing housing support for students and staff, have contributed to gentrification and displacement in neighborhoods surrounding universities, creating the context for interrelated struggles for the right to the city and the right to the university. Using Temple University in Philadelphia, and University of California Santa Cruz as case studies we examine how students, faculty, and other university actors are joining with organizations and movements in surrounding communities to resist restructuring and displacement. In doing so, these emerging coalitions are transcending the more divisive town/gown narrative, forging new solidarities that are reimagining more just and equitable futures for both the city and the university.

This article underscores healthy tensions of navigating youth participatory action research (YPAR) and writing in an academic and intergenerational context. Counter-storytelling (Solórzano & Yosso 2002) is used as a method to unveil parallels across two different geographic contexts. Echoing the words of Gloria E. Anzaldúa, while we may be scared to write, we are more scared of not writing (Anzaldúa, 1981). This paper unveils experiences of displacement across two different geographic contexts among high school youth and the tensions embedded in the writing process across an intergenerational collective. In the words of Mr. Gar from OK K.O.!: Let’s be heroes: “sometimes it is the things we are ashamed of that are worth being proud of.” Thus, we begin by revealing what it means to write as youth, as adults afraid to write for the youth. It is here in this space that we, an intergenerational collective, make the choice to write together.

Published: April 2021

Ngabuburit in Indonesian society is a tradition that has been inherited from past generations. The practice of  Ngabuburit however has been hampered due to the COVID-19 pandemic. To prevent the spread of COVID-19 virus, the government issued several regulations. These regulations make it more difficult for the community to practice Ngabuburit. This study was conducted to find out the effects of the COVID-19 pandemic on Ngabuburit, the interest of  university students in Bandung in practicing Ngabuburit,  and to find out the best method to practise Ngabuburit tradition amidst the COVID-19 pandemic according to university students. Methods used in this study are literature study and primary data collection through questionnaires. The research result indicates that COVID-19 pandemic has reduced the intensity of Ngabuburit in Bandung. The obstruction of Ngabuburit practices correlates with the decline in the average level of happiness of students in Bandung. Even though the practice of Ngabuburit tradition is hampered, said tradition still can be carried out through online methods, namely methods that rely on internet technology so that there is no need to meet face to face. Hopefully this research will be useful for those who wish to practise Ngabuburit tradition amidst the COVID-19 pandemic.
