Authors: Önal Özgür , Gürlek Beril , Küçükosman Neslihan
Published: February 2023

Objective: The present study was conducted to adapt the Obstetric Quality-of-Recovery Score (ObsQoR-11) into Turkish and to test its validity and reliability.
Study Design: This study was designed as a methodological study, and the research population consisted of women who gave birth in the gynecology and obstetrics wards of two hospitals in Rize between January and March 2021 and who were hospitalized in the inpatient service 24 hours after delivery. We did not select a sample for the study and instead applied face-to-face questionnaires to women (vaginal delivery: 117 patients, cesarean delivery: 112 patients). Data collection tools included a questionnaire form developed by the researcher and the ObsQoR-11-TR scale.
Results: While testing the ObsQoR-11-TR scale for validity and reliability, we first used a language validity method and then exploratory and confirmatory factor analysis methods. Accordingly, the ObsQoR-11-TR scale had a KMO (Kaiser-Meyer-Olkin Measure of Sampling Adequacy) value of 0.833 and a Bartlett's Test of Sphericity chi-squared value of 1818.396 (p<0.05). The two-factor model created here explained 69.39% of the variance. According to the exploratory factor analysis results, the factor loads of the items ranged from 0.490 to 0.920, and all items except one displayed factor load greater than 0.774. Again, according to the exploratory factor analysis, the scale was found to consist of two factors. This is consistent with the scale's original form. We used Cronbach's alpha test to calculate the reliability of the scale. Cronbach's alpha value was found to be high (0.781) for the whole scale and excellent for factor 1 (0.850) and factor 2 (0.920).
Conclusions: Our validity and reliability tests conclude that the ObsQoR-11-TR consists of 11 items and 2 subscales and is a valid and reliable scale for Turkish society.

Authors: Ari Mehmet Semih , Tandogan Kamer , Özkul Ayça , Cabala Murat , Güzelbey Tevfik
Published: February 2023

Objective: The COVID-19 disease affected most hospitals with its rapid spread and increased number of severe cases. Thus, delays in acute ischemic stroke care and a decline in hospitalization and interventions, such as endovascular thrombectomy, have been reported. With the present study, we aimed to evaluate baseline patient characteristics and determine the impact of pandemics on MT-related outcomes.
Materials and methods: The hospital database was scanned for the patients diagnosed with acute ischemic stroke and treated via mechanical thrombectomy. The patients enrolled in the study were evaluated for their demographic features, infarct characteristics, clinical neurological scores (NIHSS and mRS) on admission and discharge, the TICI results, and the clinical course of the disease.
Results: 250 patients were diagnosed with acute ischemic stroke during the Sep.2020-Oct.2021 period. Of the 158 patients were eligible for mechanical thrombectomy. Among the patients who underwent MT, 8 (5.06%) were diagnosed with COVID-19. While the median NIHSS score on admission was 12 (±4.16), the final post-procedural NIHSS score on discharge was 6 (±5.00). The most commonly occluded artery was MCA in 128 (81.01%) patients. While 76 (%48.10) of the patients resulted in procedural success with a TICI 3 score, a post-procedural intracranial hemorrhage was observed in 35 (22%) patients. A total of 90 (%56.96) patients were discharged with a good neurological outcome, while 32 (%20.25) had a lethal result. The outcome data of some patients (32 (%20.25) in particular) could not be obtained. Those patients needed to be referred to another ICU after the MT procedure because of the present hospital's lack of ICU beds.
Conclusion: The rate of COVID-19 infection was low among stroke patients who underwent MT. Moreover, all patients who underwent intervention due to a lack of intensive care beds could not be followed up in our hospital and had to be referred to an external center.

Authors: Özkan Öztürk Semra , Kocaman Zehra , İnal Ali
Published: February 2023

Objective: Coronavirus disease-19 (COVID-19) is one of the large-scale pandemics affecting the whole World. Breast cancer is the most common cancer in women. This study aims to examine the factors that may be effective on COVID-19 disease severity in breast cancer patients.
Material and Methods: This study was carried out as a single-center and retrospective study with a total of 65 patients with a pathological diagnosis of breast cancer who were hospitalized between April 2020 and June 2021. The patients were divided into two groups, mild and severe. 35 patients were in the mild group and 30 patients were in the severe group. Patients with oxygen saturation below 93 percent, needing non-invasive or invasive mechanical ventilation, acute respiratory distress syndrome, shock, and multiple organ failure were included in the severe group.
Results: A total of 17 parameters that may affect disease severity were analyzed. As a result of the univariate analysis performed to evaluate the potential factors that may affect the severity of the disease, statistically, significant differences were found: the patient had diabetes mellitus (P=0.050), the neutrophil count increased during hospitalization (P=0.002), the lymphocyte count decreased at admission (P). =0.001), high d-dimer level during hospitalization (P=0.007), lymphocyte to monocyte ratio above 2.55 (P=0.016).
Conclusion: As a result, the presence of diabetes mellitus, neutrophilia, lymphocytopenia, high D-dimer, and increased lymphocyte to monocyte ratio in patients with breast cancer may aggravate the course of COVID-19 disease. These parameters may be predictive for closer follow-up in terms of clinical deterioration of the patients.

Wrong Line: Proposing a New Test for Discrimination Under the National Labor Relations Act
Authors: Rosenberg Daneri Joshua , Thomas Paul
Published: February 2023

There has long been a consensus among scholars and union-side practitioners that the National Labor Relations Act (NLRA) is under-enforced. As a result, employers often treat violations of the NLRA as a cost of doing business rather than a serious violation of a federal statute. Calls for reform have historically tended to propose legislative amendments to the NLRA to constrain employer conduct and impose greater consequences for discrimination violations. However, little attention has been given to improving the flawed legal test by which such discrimination is analyzed, Wright Line, 251 N.L.R.B. 1083 (1980), enforced 662 F.2d 899 (1st Cir. 1981), cert. denied 455 U.S. 989 (1982). In this article, we propose a new causation test that better addresses how adjudicators should weigh the evidence that Congress and jurists have deemed relevant for evaluating discrimination claims. Our test lightens the initial burden to establish a showing of discrimination, formalizes the employer’s defense burden, and then provides a rebuttal burden for the discriminatee. This is no radical departure from historical precedent. Rather, we argue that the original Wright Line decision itself contained hints of our test, but that adjudicators and practitioners alike have whittled Wright Line to an oversimplified shell at best and an ambiguous, complex inquiry at worst. Our test better fulfills the NLRA’s objective of promoting collective bargaining in the private sector by encouraging a deeper inquiry in NLRA cases’ pre-litigation investigative stage.

Between socialist homeland and totalitarian dictatorship. The image of the post-World War II period in Ukrainian historical discourse
Authors: Studenna-Skrukwa Marta
Published: February 2023

This paper is devoted to the analysis of selected aspects how Ukrainian schools present the historical narrative that covers the post-World War II history of this country – particularly the period of late socialism. My goal was to establish how post-Maidan textbooks presented the times when Ukraine was part of the Soviet Union in its superpower phase. I was especially interested in the current assessment of such phenomena as: post-Stalinist modernization, the movements opposing communist ideology, and the late socialist concept of the Soviet people. The source material was five new textbooks for historical education at high-school level approved for use by the Ukrainian authorities in 2019. The basic research method was discourse analysis: the content of the textbooks were critically evaluated in light of the ongoing political and social situation. Among the theoretical assumptions that were applied in the paper was that the historical narrative has a key importance as a function of the nation-state and as such serves its interests. To conclude the analysis below, it should be emphasized that historical narrative of Ukrainian Schools presents the past of the country in the second half of the 20th century as a general process of gaining independence from the Soviet centre. In the context of Russia’s aggression against Ukraine, it should be assumed that the emancipatory nature of the interpretation of Ukraine’s national history is now irreversible.
Totalitarianism versus humanitarian-personalist concept of socio-political life according to Cardinal Stefan Wyszyński
Authors: Ficek Ryszard
Published: February 2023

This paper studies the multifaceted and definitude specificity of totalitarianism in the context of the humanitarian-personalist concept of the socio-political life of Cardinal Stefan Wyszyński. The analysis of the discussed topics provides a unique insight into the nature of totalitarianism, in both the version of German Nazism and in Communism with the Soviet origin and provenances. However, the reinterpretation of the above systems from the perspective of Christian personalist praxeology allows one to notice and present the fundamental assumptions of these concepts’ entirely anti-human and anti-Christian paradigm. Moreover, unveiling the entire agenda of totalitarianism makes it easier to interpret these concepts in terms of not only defining but also legitimizing, and even authenticating, some of the most terrifying and degenerated systemic government-ruling forms of the 20th century. It is of crucial importance, especially nowadays, when the emerging trends often downplay and soften the criminal nature of the above systems and even consider the “totalitarian model” as a “specific historical phenomenon” attempting to resolve many crucial but complex issues of political, cultural, and economic nature.

Authors: Quin Grégory , Vonnard Philippe , Mayencourt Gil , Cala Sébastien
Published: February 2023

The present contribution presents the results of the eponymous research project, which focuses on the understanding of the genesis and structure of the Swiss sports field between the 1860s and the 1930s. During this period, national umbrella organisations for all physical activities and sports developed. Within the framework of this project, which focuses on several sports (gymnastics, shooting, national games, football and cycling, with the addition of skiing on the basis of related doctoral work), we will present our main results, in particular on the organisations in charge of the governance of the sports identified as central, in order to shed light on the struggles but also on the links that were to be forged between them, as well as to question the recruitment, the profiles and the motivations of their leading elites. Based on the collection and analysis of unpublished documentation, especially prosopographical, this project brings to light a double original process to which the space of physical and sports activities is subjected: on the one hand, that of sportivisation, on the other hand, that of nationalisation. In the framework of this contribution, we will present a selection of emblematic cases of presidents of Swiss sports federations, at the time of the Fin-de-Siècle and up to the interwar period, o compare the different traditions existing in the studied sports and to underline the processes leading to the status of “national sports”.

Authors: Ibrahim Zaharah , Akbar Amir Azhar , Steward Davina Law , Ismail Razali
Published: February 2023

One of the ways to reduce the pollution of rivers is to treat wastewater at the source point. This can be accomplished by building a Biologically Active Filter (BAF) at source point of drainage system to treat the wastewater before it is being discharged into the river. The BAF is distinguished from other filtration system because there is a separation between the microorganisms and the treated wastes. The method of filtration is a combination of both physico-chemical adsorption and in-situ bioremediation. A bench scale BAF was setup using natural materials as its filtering media. Indigenous microorganisms from the wastewater with optimum pollutant degradation capabilities have been isolated and added into the BAF, to enhance the biodegradation of wastewater. With its biological regeneration capabilities, this system should serve as a sustainable, effective, and economic filtration method for various industrial wastewater and discharge. Influent and effluent qualities have been evaluated based on physical, chemical and biological parameters.

Authors: Arora Sangeeta , Chopra A. K. , Prasad G. , Joshi N.
Published: February 2023

The present paper deals with the physico-chemical characteristics of Doon Distillery, Doiwala effluent and its in-vitro effect on seed germination of four agricultural crops i.e. Solanum melongena (Brinjal), Cicer arientinum (Black gram), Glycine max (Soyabean) and Lycopersicon esculentum (Tomato). The physico-chemical characteristics showed high degree of pollution load in the effuent as it is evident by high degree of BOD (35375mg/l), COD (81000 mg/l), MPN/100 ml (30.56x105) and SPC (72.33x106). The effect of effluent treatment on seed germination in-vitro showed a significant negative co-relation between different concentration of the effluent (5 to 100%) and in percentage of seed gemination of S.melongena, C. arietinum, G.max & L. esculentum. In all these four crops maximum percentage of seed germination was observed at 5% concentration of effluent. Germination of seeds treated with different doses was only recorded up to 25% concentration. Effluent showed deleterious effect at 50% and above that no seed germination was found.

Diagnostic accuracy of Non-ECG Gated Chest CT (NEGCT) for cardiac chambers’ dimensions in comparison with echocardiography
Authors: Hafeez Mahnoor , Sattar Amjad
Published: February 2023

Objective: To analyze the accuracy of Non-ECG Gated Chest CT (NEGCT) for cardiac chambers’ dimensions, keeping Echocardiography as the gold standard.

Methods: After IRB approval, all patients that underwent concurrent contrast chest CT/CTPA and transthoracic 2D echocardiography exam at our institute within 1 month interval comprised the study population. Data was archived from HMIS PACS Database. The sizes of right ventricle (RV), left ventricle (LV) and left atrium (LA) was recorded in shot axis at axial CT sections and at echocardiography. RV and LV-transverse diameter was measured at basal third of the heart, from the inner to inner myocardium perpendicular to the inter-ventricular septum and LA-max. Anterior-posterior dimension was measured at the level of the aortic root.

Results: Total 213 subjects were studied, with average age of 52.1±15.8 years. The CT-Echocardiography measurement concordance rates were significantly high for LA, LV and RV measuring 93.8%, 96.7% and 69.01% respectively. Using CT threshold for LA, LV, RV enlargement > or equal to 45, 55, 35mm, the AUC via ROC curve analysis was estimated to be 0.912, 0.992, 0.650 respectively. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and diagnostic accuracy of NEGCT was found to be 66.67%, 95.10%, 37.5%, 98.5% and 93.90% for LA; 100%, 96.67%, 30.0%, 100%, 96.7% for LV and 33.33%, 74.86%, 17.86% 87.26% and 69.01% for RV respectively.

Conclusion: Overall, the accuracy of chamber dimensions at NEGCT was excellent with high CT-Echocardiography concordance, making it an alternative modality for examining chamber sizes, in the absence of cardiac MRI. Through it, a radiologist can also add more value to CT reporting.

Demographic features and outcomes in critically ill mechanically ventilated COVID-19 patients with respiratory failure in a resource limited ICU setting – Report from a tertiary care center in Karachi
Authors: Hanif Mehak , Sumalani Kamran Khan , Shaikh Zarkesh , Mandhan Vishal , Haider Shahbaz
Published: February 2023

Background: Studies done on severe COVID-19 have revealed a wide heterogeneity in intensive care clinical outcomes across various countries. We aimed to identify the demographic features and outcomes of mechanically ventilated COVID-19 patients with respiratory failure in Pakistan in resource limited settings.

Methods: This was a cross-sectional study conducted at the COVID-19 Intensive care unit (ICU) of Jinnah postgraduate medical center in Karachi, Pakistan. 86 patients who received mechanical ventilation in a period of five months from 1/2/2021 till 30/6/2021 were included in the study. Patient demographic characteristics, comorbidities, clinical manifestations of COVID-19 infection, laboratory values at the time of presentation (hemoglobin, Neutrophil lymphocyte ratio, platelets, glomerular filtration rate, C-reactive protein, D-dimers, Ferritin, liver function tests and electrolytes) and mode and duration of ventilation, final outcome (survivor vs. non-survivor) and cause of death in non-survivors were recorded.

Results: 86 patients, who required mechanical ventilation because of severe respiratory distress not alleviated by non-invasive methods of ventilation, were included in the study. 66.3% (n=57) were males and 33.7% (n=29) were females. Mean age was 59 (SD 12). The most common comorbidities were diabetes mellitus and hypertension 44.2% (n=38) each. Only 3 (3.4%) of mechanically ventilated patients were extubated and 1 patient was eventually discharged home on room air. The mortality rate was 98.8% and only one patient survived. The most common causes of death were respiratory failure (86%, n=74), renal failure (48.8%, n=42) and sepsis (18.6%, n=16).

Conclusion: Mortality in COVID-19 patients who require mechanical ventilation is very high in resource limited settings because of the lack of essential medications, specialized teams and established protocols of ICU management and is not related to the demographic characteristics and comorbidities of patients and severity of disease at presentation.

Тенденції розвитку програмового забезпечення іншомовної підготовки магістрів-філологів у закладах вищої освіти України на сучасному етапі
Authors: Корнієнко Марія
Published: February 2023

У статті висвітлюються проблеми формування програмового забезпечення іншомовної підготовки магістрів-філологів – майбутніх учителів англійської мови, зумовлені трансформаційними процесами, що відбуваються в українській освіті загалом і вищій школі зокрема. Авторка зосереджується на програмовому забезпеченні саме магістерської підготовки, оскільки другий рівень вищої освіти має високий  потенціал для формування компетентного фахівця-новатора, свідомого рушія суспільного розвитку.

У роботі використані дисертаційні дослідження й монографічні праці вітчизняних учених стосовно загальних засад розвитку магістратури та ступеневої підготовки вчителів іноземних мов, переважно – англійської.

Аналізуються основні тенденції програмування магістерської освіти в Україні наприкінці минулого й на початку нинішнього століття, найважливішими з яких є диференціація змісту навчання і форм контролю за його результатами на різних рівнях вищої освіти, варіативність змісту навчання та його компетентнісна спрямованість, європейська інтеграція та особистісна зорієнтованість фахової підготовки. Стверджується тісний зв’язок між освітньо-професійною програмою та програмами навчальних дисциплін.
