Abstract

Introduction: The formation of malignant pleural effusion (MPE) is a clinical manifestation of an advanced malignancy or its dissemination. The focus of treatment is primarily palliative and aimed at relieving symptoms, especially dyspnoea.

Material and Methods: Clinical data from patients who were hospitalized at the Clinic of Thoracic Surgery, JFMED CU and Martin University Hospital, in the years 2015–2019 were retrospectively explored and statistically analyzed based on their medical records.

Results: From the group of patients with proven MPE (n=67), 32 patients were male (48%) and 35 were female (52%). The mean age was 62.3 years (65.4 for males and 59.4 for females). The three most common primary malignancies were lung cancer (n=24), breast cancer (n=14), and kidney cancer (n=6). In 38 patients with MPE a talc pleurodesis via VATS was performed, with a median survival of 341 days (95% CI 256–859). Drainage following the talc slurry pleurodesis was performed in 10 patients with a median survival of 91.5 days (95% CI 64-NA). Ten patients with MPE underwent drainage only. The overall median survival time after all types of surgical interventions was 301 days (95% CI 207-389 days).

Conclusion: Management of MPE depends on the patient´s prognosis. A definitive intervention is required in patients with a long-term survival, while in patients with a short life expectancy procedures leading to the shortest hospital stay are preferred. Videothoracoscopic procedures with pleurodesis represent an effective treatment for patients with symptomatic MPE with a good performance status, presence of lung re-expansion following pleural drainage or expected survival.

Published: April 2021

Abstract3,4-methylenedioxymetamphetamine (MDMA), also known as “ecstasy”, “tulips”, or “Molly”, is an increasingly used “recreational drug” particularly among teenagers and young adults along with the widespread conviction that MDMA is a “safe drug”. The reason for this substance being abused is a desire for closeness to other people, develop a greater tolerance of their views and feelings, and even to touch them physically. According to these effects MDMA is classified also as an “empatogenic” or “entactogenic”. Although MDMA is used for the above-mentioned socially acceptable purposes, in many individuals the drug usage is followed with side-effects varying from mild to severe, potentially even life-threatening. One of the most significant complication of MDMA intoxication is hyper-thermia in the consumer. Authors presented a case of MDMA toxicity with severe hyperthermia (42 ºC) with a fatal outcome to the ecstasy-influenced subject. The aim of this article is to describe the effects of ecstasy, the “recreational drug” widely used in local pubs, dance clubs, and during open air festivals, even in the Slovak Republic.

Abstract
Yellow dwarf viruses (YDVs) are economically destructive viral diseases of cereal crops, which cause the reduction of yield and quality of grains. Cereal yellow dwarf virus-RPV (CYDV-RPV) is one of the most serious virus species of YDVs. These virus diseases cause epidemics in cereal fields in some periods of the year in Turkey depending on potential reservoir natural hosts that play a significant role in epidemiology. This study was conducted to investigate the presence and prevalence of CYDV-RPV in grasses and volunteer cereal host plants including 33 species from Poaceae, Asteraceae, Juncaceae, Geraniaceae, Cyperaceae, and Rubiaceae families in the Trakya region of Turkey. A total of 584 symptomatic grass and volunteer cereal leaf samples exhibiting yellowing, reddening, irregular necrotic patches and dwarfing symptoms were collected from Trakya and tested by ELISA and RT-PCR methods. The screening tests showed that 55 out of 584 grass samples were infected with CYDV-RPV in grasses from the Poaceae family, while none of the other families had no infection. The incidence of CYDV-RPV was detected at a rate of 9.42%. Transmission experiments using the aphid species Rhopalosiphum padi L. showed that CYDV-RPV was transmitted persistently from symptomatic intact grasses such as Avena sterilis, Lolium perenne and Phleum exratum to barley cv. Barbaros seedlings. PCR products of five Turkish RPV grass isolates were sequenced and compared with eleven known CYDV-RPV isolates in the GenBank⁄ EMBL databases. Compared nucleotide and amino acid sequences of CYDV-RPV isolates showed that the identities ranged from 40.38 − 95.86 % to 14.04 − 93.38%, respectively. In this study, 19 grass species from the Poaceae family and two volunteer cereal host plants were determined as natural reservoir hosts of CYDV-RPV in the cereal growing areas of Turkey.

Abstract
The paper presents the strength evaluation of planetary gear teeth designed for a radial sedimentation tank drive. A novel type of gear drive, composed of a closed epicyclic gear train and an open gear train with internal cycloidal gear mesh is proposed. Contact stress and root stress in the planetary gear train were determined by the finite element method and according to ISO 6336. The influence of the mesh load factor at planet gears on stress values was also established. A comparison of the results followed. It was observed that the mesh load factor on satellites depends mainly on the way the satellites and central wheels are mounted, the positioning accuracy in the carrier and the accuracy of teeth. Subsequently, a material was selected for the particular design of planetary gear and the assumed load. The analysis of the obtained results allowed assuming that in case of gears in class 7 and the rigid mounting of satellites and central wheels, gears should be made of steel for carburizing and hardening. In case of flexible satellites or flexible couplings in the central wheels and gears in class 4, gears can be made of nitriding steel.
Functional Behavior of Pseudoelastic NiTi Alloy Under Variable Amplitude Loading
Authors: Iasnii Volodymyr , Yasniy Petro , Lapusta Yuri , Yasniy Oleg , Dyvdyk Oleksandr 
Published: April 2021

Abstract
Cyclic loading of superelastic NiTi shape memory alloy (SMA) causes forward and reverse austenite–martensіte transformations, and also increases the volume of stabilized martensite. This appears in the change of stress-strain curve form, the decrease of dissipation energy, and increase of residual strain, that is, named transformation ratcheting. In real structures, the SMA components in most cases are under the action of variable amplitude loading. Therefore, it is obvious that the loading history will influence the functional fatigue. In the present work, the effect of stress ratio on the functional properties of superelastic NiTi shape memory alloy under variable amplitude loading sequence with two blocks was investigated. The studies were carried out under the uniaxial tension of cylindrical specimens under load-full unload and load-part unload. The change of residual strain, strain range, dissipation, and cumulative dissipation energy density of NiTi alloy related to load sequences are discussed. Under both stress ratios, the residual strain in NiTi alloy is increased depending on the number of loading cycles on the high loading block that is similar to the tests at constant stress or strain amplitude. An unusual effect of NiTi alloy residual strain reduction with the number cycles is found at a lower block loading. There was revealed the effect of residual strain reduction of NiTi alloy on the number of loading cycles on the lower amplitude block. The amount of decrement of the residual strain during a low loading block is approximately equal to the reversible part of the residual strain due to the stabilized martensite. The decrease of the residual strain during the low loading block is approximately equal to the reversible part of residual strain due to the stabilized martensite. A good correlation of the effective Young’s modulus for both load blocks with residual strain, which is a measure of the volume of irreversible martensite, is observed.

Abstract
With the rapid increase of information generated from all kinds of sources, temporal big data mining in business area has been paid more and more attention recently. A novel data mining algorithm for mining temporal association is proposed. Mining temporal association can not only provide better predictability for customer behaviour but also help organisations with better strategies and marketing decisions. To compare the proposed algorithm, two methods to mine temporal association are presented. One is improved based on a traditional mining algorithm, Apriori. The other is based on an Index-Tree. Moreover, the proposed method is extended to mine temporal association in multi-dimensional space. The experimental results show that the Index-Tree method outperforms the Apriori-modified method in all cases.
Integrated Reporting Performance – Effect of Organizational Behavior Development

Published: April 2021

Abstract
The effects of the economic crisis and the numerous financial failures of major companies call into question the reliability of financial reporting, which is considered insufficient in reflecting the clear and complete picture of performance, assessed in financial, environmental and social dimensions. In order to obtain an integrate report, it is necessary to combine both financial and non-financial information. Non-financial reporting supports and complements the classic ones, but the complexity of the information provided must also be taken into account, as the phenomenon of opacity may occur, not only due to lack of transparency but also due to difficulty of understanding by users and producer of financial information. Therefore, in the context of long-term global interests, to support sustainable development it becomes important to bring to the research area the identification of the current stage of implementation of integrated reporting with the exemplification of the ranking of sustainability reports of companies listed on the Bucharest Stock Exchange (BSE).

Psychostimulant Subtances Use Among Resident Doctors
Authors: Iacob Diana-Andreea 
Published: April 2021

Abstract
The use of psychostimulants is more and more common lately, especially in the medical guild. The term “burn-out” is an occupational phenomenon, not a disease, and 25-60% of doctors in different specialties have the burn-out syndrome. The method was to complete a questionnaire-type test by 204 medical residents. The results shows us that 72.1% (147) of the respondents drinks coffee, 25.9% of them smokes cigarettes during hospital hours and 13.7% consumes energy drinks. Furthemore 5.9% drinks alcohol during shifts. Among of all, those who are consumers of at least one psychostimulant substance, the risk of them having at least one of the symptoms of burnout is 1.3 times higher than those who do not consume anything at work (RR-1.3453, p = 0.0152). Psychostimulant substances are consumed to improve the efficiency and resistance at work. It’s important to manage the time in order to avoid extreme fatigue and distress.
Haemorrhagic Cerebrovascular Accident (CVA) Etiology and Case Report
Authors: Luchian Mihaela , Săceleanu Adriana 
Published: April 2021

Abstract
A haemorrhagic cerebrovascular accident refers to a spontaneous bleeding in the cerebral parenchyma, located either supratentorial or infratentorial, that occurs in the absence of a surgical or traumatic cause. The incidence is estimated at 12-15 new cases per 100.000 inhabitants per year. Intracranial haemorrhage is the third most frequent cause of stroke, the vast majority being represented by primary/hypertensive (spontaneous) intracerebral haemorrhage, ruptured saccular aneurysm, a vascular malformation or haemorrhage associated with the use of anticoagulants or thrombolytic agents. A cerebral tomography computer examination is the examination of choice in diagnosis of haemorrhagic CVAs. The treatment can be either therapeutic or surgical, depending on the case, with the consideration that an immediate medical treatment is mandatory for the best odds of recovery.(1)
The Efficiency of Pulse Therapy with Glucocorticoids in Inflammatory Orbital Disorders: Case Report
Authors: Lebădă Ioana-Codruţa , Stanciu Mihaela 
Published: April 2021

Abstract
Orbital pseudotumor represents a benign inflammatory disorder of the orbit, with unspecified etiology, whose clinical presentation can mimic the ocular pathology of Basedow disease, namely Graves’ ophthalmopathy, the two of them representing two of the most common orbital conditions. Imagistic methods and laboratory analyses can establish the diagnosis through orbital MRI images specific for the orbital pseudotumor, especially by dosage of the TSH receptor antibodies (TRAb) which will have increased values in Basedow disease with ocular damage. In both situations, the treatment is represented as a first therapeutic line by administration of corticotherapy in high dosage orally or intravenously, with favorably evolution, which is also observable in the case of our patient who was diagnosed with orbital pseudotumor based on MRI images, with associated thyroid dysfunction with negative TRAb, in which the pulse therapy with Solumedrol has determined the improvement of ocular symptoms and signs.

Published: April 2021

Abstract
Being considered a rare form of malignant neoplasm, stromal tumours are part of sarcomas group, they account for ~5% of all sarcomas (1), which develop from the supporting tissues of the body and have as a starting point special cells located in the wall of the gastrointestinal tract, called interstitial cells - described by Cajal. Although this type of tumour formations poses the problem of diagnosis, when it is made early and surgical and oncological treatment is prompt, the prognosis improves considerably.

Published: April 2021

Abstract
The main objective of the study was to determine the effect of transition from a conventional milking system (CMS) to an automatic milking system (AMS) on survival of 6361 Polish Holstein-Friesian cows to second (SL2), third (SL3) and fourth (SL4) lactation as well culling reasons. The cows were born between 2002 and 2015 and calved between 2004 and 2018. All data for the survival analysis and culling reasons of cows in 17 herds during operation of CMS and AMS were extracted from the SYMLEK official milk recording system. Cow survival (SL2, SL3 and SL4) was analysed with multiple logistic regression using the following effects in the model: milking system (MS), first calving season (CS), age at first calving (AFC), ease of first calving (CE), birth of a dead calf at first calving (DC), milk yield (MY) for full first lactation (MY – this effect was ignored in SL2 analysis), herd (H), and MS × H interaction. In the next stage of the study, χ2 test was used to analyse culling reasons of cows (udder diseases, low fertility – infertility and reproductive disorders, locomotor diseases, low milk yield, other diseases – metabolic, digestive and respiratory diseases, accidents and chance events) in the first, second and third lactation and collectively in the first three lactations. Logistic regression analysis indicated a significant effect of MS, AFC, DC on SL2 and SL3, and of MY on SL3 and SL4. Moreover, H and MS × H interaction had a highly significant effect on SL2, SL3, and SL4. Cows used in AMS barns were characterized by significantly worse SL2 and SL3 compared to CMS (odds ratio), by 27.8% and 31.0%, respectively. It was also observed that the effect of switching from CMS to AMS on cow survival was determined by herd membership – in most herds this effect was unfavourable. A distinctly positive effect of milking automation on cow survival (SL2, SL3, SL4) was noted in only one barn (herd) – it was a new barn with a considerably expanded number of milked cows, where the lying area was covered with straw. When analysing the reasons for culling in the first three lactations collectively, it was found that after the AMS system was introduced into the herds, there were increases in the rate of culling for locomotor diseases (by 0.85 percentage points (p.p.)), low milk yield (1.36 p.p.) and other diseases (3.01 p.p.). It was also observed that the automation of milking reduced culling due to udder diseases by 0.37 p.p., low fertility by 3.24 p.p., and accidents and chance events by 1.60 p.p.

Published: April 2021

Abstract
The objective of the present study was to analyze the morphometric variations of the three presumed taxa within the Barbonymus group, namely B. gonionotus, referred to locally as naleh; B. schwanenfeldii, referred to locally as lampam-A; and Barbonymus sp. referred to locally as lampam-B. The naleh samples were collected from Nagan Raya District, while lampam-A and lampam-B were collected from Aceh Tamiang District, Indonesia. Traditional morphometric characters were measured in 150 fish samples (50 individuals of every taxon). The results of univariate (ANOVA) and multivariate (Discriminant function analysis, DFA) analyses showed that lampam-A and lampam-B have overlapping morphological characteristics, whereas naleh were distinctly different. Therefore, it is presumed that lampan A and lampan B are the same species of B. schwanenfeldii. It was concluded that the morphometric data indicated that there are two species of Barbonymus in Aceh waters, i.e., B. schwanenfeldii and B. gonionotus.

Abstract
The aim of the study was to compare the quality and quantity parameters of semen in male lake minnow, Eupallasella percnurus (Pallas, 1814), from six Polish populations. Substantial differences among the populations were found in milt volume (36–112 µl) and sperm concentration (4.7–8.0 × 109 ml−1). Mean values for sperm motility were similar; however, there were population-related differences in sperm velocity measured with VSL (96.3–127 µm s−1). Despite this, the quality of semen in all cases was high and appropriate for both artificial reproduction and cryopreservation.
Optimization of SPE method for the extraction of 12 neurotransmitters from sheep brain
Authors: Tampu Raluca , Tampu Catalin , Elfakir Claire 
Published: April 2021

Abstract
The present paper presents our attempts concerning the development of an extraction method for catecholamines. In order to achieve the extraction of all the selected solutes using a single SPE cartridge, several types of support were tested, among them: cation exchange supports, hydrophilic-lipophilic supports, C18 supports and PGC supports. As unfortunately none of the supports tested offered us the possibility of carrying out the extraction of 12 catecholamines from our standard mixture, we chose to use a coupling of two different cartridges: Oasis HLB and PGC which together ensure the extraction of all the compounds of the mixture with good extraction yields and with simple protocols. The selected cartridges were successfully tested for the extraction of a sample spiked from sheep brain with the 12 catecholamines in our mixture. The SPE method that we have developed allows the purification of the samples (a significant part of the components of the matrix is eliminated during this step) and also a preconcentration of the samples.
