DEATH AS A PROBLEM OF LIFE:YURI LOTMAN, ROLANDAS PAVILIONIS, ALEKSANDR PIATIGORSKY
Summary
Aware of the distinctiveness of the thinking of the philosopher and the philologist, the author has extracted the theme of death from the texts of Yuri Lotman, Rolandas Pavilionis, Aleksandr Piatigorsky, emphasizing that it has appeared in the works of these writers without any religious background, in the purely phenomenological dimension. The article is broadened with reflections on the works concerning the title theme authored by Vladislav Khodasevich, Anna Akhmatova and Merab Mamardaszvili.
And everything that is happening within me is also a part of the universe: several notes on Rolandas Rimkūnas` drawings
No full textStraipsnyje aptariama kauniečio menininko Rolando Rimkūno kūryba, pasitelkiant kontekstinį-biografinį modelį ir derinant biogramos, laisvos formos interviu ir dailėtyrininko postinterpretaciją. Remiamasi prielaida, kad norint perprasti Rimkūno kūrybą tokia kontekstinė prieiga yra adekvatesnė nei sausi menotyriniai išvedžiojimai. Taigi šio teksto pirminei struktūrai didelę reikšmę turi paties Rimkūno pasakojimai, paaiškinimai ir patikslinimai. Vis dėlto, net aptariant Rimkūno kūrybą tokiu „betarpišku“ aspektu, galima išskirti tam tikrus kūrybos bruožus, kuriuos dailėtyrine prasme galima būtų apibūdinti kaip savitą kritinio regionalizmo atšaką. Reikšminiai žodžiai: Kauno menininkai; Rolandas Rimkūnas; Piešiniai; Grafika; Kontekstinis požiūris; Kritinis regionalizmas; Kaunas` artists; Rolandas Rimkūnas; Drawings; Graphic art; Regional criticism; Contextual viewThe article discusses the works of the Kaunas’ artist Rolandas Rimkūnas through the specific means of contextual view. Preferential attention is focused on Rimkūnas’ biography that is seen in terms of the larger cultural, social and historical contexts. The author of this article argued that such "biographical-contextual sketch" structure of an article reflects the works of Rimkūnas better than any complicated formulas of art criticism. Rimkūnas creates drawing or graphic cycles which derive from the real life situations of more complex existential circumstances. So the author tries to look at the works of Rimkūnas "phenomenologically" – to look at the drawingcycles in the context of his "life-cycles". Some of the more important features of Rimkūnas’ intellectual and creative biography are also discussed. In this case Rimkūnas’ tellings and explanations (conversations with Rimkūnas) have become very important. However, the art of Rimkūnas includes certain features. Mostly the artist draws using biros or felt-tips. According to Rimkūnas, this technique of drawing is the easiest way to create his visual diaries. We could perceive Rimkūnas’ art as a specific kind of critical or local regionalism. This article presents Rolandas Rimkūnas as an ironic moralist in the (global) tradition of the works of William Hogarth, Francisco Goya, Honoré Daumier, The Peredvizhniki (Wanderers), Jaroslav Hašek or Pupų Dėdė
Attitude of the Lithuanian public toward medical assistance in dying: a cross-sectional study /
No full textEuthanasia and assisted suicide, involving the intentional termination of a patient’s life, are subjects of global debate influenced by cultural, ethical, and religious beliefs. This study explored the attitudes of the general public toward euthanasia, finding varying levels of support. A cross-sectional study was conducted. This research specifically evaluated the perspectives of 5804 Lithuanian residents using a survey distributed through social media, which presented medical scenarios on life-preserving interventions. Analysis indicated that gender, religion, experience in caring for patients in a terminal condition, education, and age significantly influenced the attitudes of the respondents toward end-of-life decisions. Specifically, factors like being non-religious or having less experience in caring for the terminally ill correlated with a more positive opinion regarding euthanasia and other forms of medical assistance in dying
Angus beef cattle bull growing applying new feed technology
No full textAuthor: Audrius Stelmokas, student of Lithuanian University of Health Sciences of Veterinary Academy Faculty in animal science master’s degree program. Work manager: Professor, doctor Rolandas Stankevičius. Master thesis: “Angus beef cattle bull growing applying new feed technology” The aim of the thesis: to evaluate if the feeding technology until weaning will have any impact on bulls daily gain weight and what affect it will have later on fattening. The tasks of the thesis: to clarify benefits of cereal grain feed until weaning by weighing bulls after weaning and in the fattening. The research methods and results: to complete the research we picked 3 test groups from 3 different Angus cattle breeders in Lithuania which had different feeding technologies until weaning. Fattening took place in White sheep cooperative farm in fattening station. Weights were done every 3 weeks. To collect weights we used “Load Bars MP1010”. First test group – Pure Fields breeder gave bulls cereal grains “ad libitum” which averagely consumed about 1.83 kg. per day. Second group – Black Angus Hill’s bulls consumed 1 kg per day for one bull. The third test group – Red Angus bulls didn’t get any cereal grains until weaning. Cereal grains were produced and supplied by company “Kauno Grūdai”. Quality of forage feed in fattening were determined by “Lietuvos žemės ūkio konsultavimo tarnyba“ using “AgriNir” pasture analyzer. At the start of fattening the best group with 1.229 daily gain were bulls that received cracked grains ad libitum. Second best bulls were from Black Angus Hill breeder with 0.998 daily gain. And the lowest group was cattle from Red Angus breeder which didn’t give any cereal grains with 0.901 daily gain. Nevertheless all 3 groups produced significantly good results in fattening farm gaining from 1.320 kg per day to 1.491 daily gain

No full textSubject: Influence of nutrient factors on the formation of cat hairball in the stomach. Author: Ieva Lotužaitė. Head of the work: Associate Professor Rolandas Stankevicius. Purpose of the study: To evaluate the causes of the formation of cat hairball in the stomach and to analyze the results of the cats' coprology obtained from UAB Vetpulsas Veterinary Hospital. Methodology:The data of the research on coprophytics was collected by UAB \"Vetpulsas\" in the Veterinary Clinic of Dogs, Cats and Exotic Animals 2016-2017. To find out how cat fodder is being absorbed. Also, in order to find out the opinion of catteries, an additional survey was selected to conduct a questionnaire survey, as well as an online and general analysis of data statistics. 251 cat hosts participated. Results: After cat co-mortem research carried out at the Vetpulsas Veterinary Clinic of UAB, cat owners rarely examine their cat's cats. 12 cats have found a secret bleeding, which indicates that the cat's diet is inappropriate. 7 villages were found in the use of crystal oxalates - excessive amounts of minerals are fed to the cat, as well as inappropriate feed. 10 cats have been found - cat food is polluted ornegative in the environment. According to the questionnaire data collected 177 cat owners comb their animals, as this most reduces the animals at risk of catching cows. 145 cats are given to the owners a herb, which facilitates the passage of hair germs. The results of the questionnaire analysis revealed that the formation of cats in the stomach is not only long-feline cats, but also short-term ones

Dirofilariasis presenting as pleural effusion: a rare case report with unusual manifestations and treatment modalities /
No full textBackground: We present an extremely rare manifestation of dirofilariasis in the pleural cavity. This is the first human pulmonary dirofilariasis reported in Lithuania; according to our knowledge, only two other patients were documented with this pathology in the world. Case presentation: A 72-year-old woman was admitted to the hospital complaining of dyspnea, left-side chest pain, and a dry cough. She was a retiree living alone in the countryside without domestic pets (sometimes stray dogs appear) or a travel history. A complete blood count was within normal limits, with a CRP level of 16.8 mg/l and D-dimer concentration of 900 µg/l, which raised suspicion of pulmonary embolism. In chest computed tomography angiography, pulmonary embolism was excluded, and only left pleural effusion without abnormal lesions was confirmed. Left thoracocentesis was performed, and the pleural fluid was evaluated as an exudate with a predominance of eosinophils (59%), along with the presence of parasites. These parasites exhibited the morphology of Dirofilaria repens. Oral doxycycline (100 mg, twice daily) and albendazole (400 mg, twice daily) were prescribed for a 14-day course. A month later, there were no pathological findings on the chest X-ray, and the patient no longer had respiratory symptoms. However, the patient presented with an emerged, painful palpable right breastmass, where the rash was previously observed. Ultrasound imaging revealed a 1.5 × 2 cm nodule, which was surgically removed. Parasites consistent with Dirofilaria repens were suspected but not definitively identified. Pharmacological treatment for dirofilariasis was not further prescribed. Conclusions: This case encourages doctors to be more vigilant because the patient, who neither travelled nor kept any pets, contracted dirofilariasis. Diagnostic and treatment guidelines are lacking, necessitating further research. Treatment with doxycycline and albendazole yielded positive outcomes, suggesting potential efficacy for dirofilarial pleuritis
Pleuros empiemos ir komplikuoto parapneumoninio pleurito priežastys ir rizikos veiksniai
No full textTyrimo tikslas. Išnagrinėti pleuros empiemos ir komplikuoto parapneumoninio pleurito priežastis ir rizikos veiksnius. Tirtųjų kontingentas ir tyrimo metodai. Ištirta 120 ligonių, sirgusių pleuros empiema (n=67) ir komplikuotu parapneumoniniu pleuritu (n=53). Pleuros empiema diagnozuota radus pūlingo pleuros skysčio. Komplikuotas parapneumoninis pleuritas diagnozuotas ultragarsiniu tyrimu, aptikus inkapsuliuoto skysčio pleuros ertmėje, pleuros skysčio pH<7,0 bei pleuros skystyje nustačius neutrofilų daugiau kaip 50 proc. visų leukocitų. Tyrimo tikslas – įvertinti tiriamųjų amžių, lytį, gretutinę patologiją, nustatyti laikotarpį, per kurį ligoniai kreipėsi į gydytoją, įvertinti, kokiais antibiotikais ligoniai buvo gydomi iki diagnozės nustatymo. Rezultatai. Pleuros empiema ir komplikuotu parapneumoniniu pleuritu sirgo vidutinio amžiaus tiriamieji (53 metų), vyrai du kartus dažniau nei moterys. 46 proc. ligonių nustatytas bent vienas rizikos veiksnys, dažniausiai neoplazija (37 proc.), imunosupresuojamųjų vaistų (15 proc.) ir nesaikingas alkoholinių gėrimų vartojimas (15 proc.). Atsiradus ligos simptomams, tiriamieji į gydytojus kreipėsi vidutiniškai po 12 dienų. Ligoniams, kuriems buvo diagnozuota pleuros empiema, rizikos veiksniai buvo dažnesni (pleuros empiemos – 50,75 proc., komplikuoto parapneumoninio pleurito – 39,62 proc. atvejų), į gydytojus jie kreipėsi vėliau (21±28,6 dienos) nei sirgusieji komplikuotu parapneumoniniu pleuritu (9,5±9,8 dienos, p=0,0052). 75 proc. tiriamųjų buvo gydyti antibiotikais, daugelis gydyti monoterapija (86 proc. atvejų). Dažniausiai buvo skiriama penicilinų (29 proc.), cefalosporinų (25 proc.), aminoglikozidų (20 proc.), makrolidų (10 proc.). 25 proc. tiriamųjų dažniausiai dėl klaidingai diagnozuotos tarpšonkaulinės neuralgijos antibiotikų neskirta. Išvada. Pleuros empiemos ir komplikuoto parapneumoninio pleurito priežastys yra daugialypės: tiriamieji, atsiradus ligos simptomams, per vėlai kreipiasi į gydytoją, beveik pusei tiriamųjų nustatytos imunosupresinę būklę galinčios sukelti patologijos, daliai ligonių neskirta antibiotikų arba jų buvo skiriama netinkamai.</jats:p
Attitudes of the Lithuanian Population toward COVID-19 Vaccination and Evaluation of Its Effectiveness: A Cross-Sectional Study
No full textBackground and Objectives: This study delves into the attitudes, beliefs and determinants influencing the uptake of the COVID-19 vaccine among the Lithuanian population. Materials and Methods: Utilizing a cross-sectional study design, a total of 3166 respondents were surveyed. Results: The findings reveal a significant disparity in vaccination rates based on socio-demographic factors, with higher uptake observed among individuals with a university degree, urban residents and those in higher income brackets. Personal beliefs, particularly regarding the vaccine’s efficacy in pandemic management, played a pivotal role in vaccination decisions. This study also highlights the influence of external factors, such as the activity of the “anti-vaxxer” movement and the introduction of vaccination certificates. Conclusions: The results emphasize the need for targeted educational interventions and comprehensive public health campaigns to address vaccine hesitancy and promote widespread immunization
