Authors: Segura Alejandro , Carvajal Nathali , Chavarro Paola Andrea , Wilches Esther Cecilia , Carvajal Argemiro 
Published: December 2019

Background: The Yang Tobin Index (Y/T) is a simple and objective measure to predict successful extubation. There are no Colombian studies supporting the use of Y/T as a predictor of successful ventilator weaning.Objective: To estimate the sensitivity and specificity of Y/T as predictor of weaning and to valuate the association with clinical and socio-demographic characteristics in adult patients at the intensive care unit.Methods: Retrospective study. We analyzed a database of 332 records of patients under mechanical ventilation (MV) for more than 48 hours, from January 2006 to December 2007, with spontaneous breathing trial and measurement of Y/T before extubation. Results: The sensitivity of Y/T was 98.6%, specificity 9.6%, positive predictive value 85.4%, egative predictive value 55.5%. The cumulative incidence of successful extubation was 84%. The greater incidence of unsuccessful extubation was associated with COPD (46.2%). The MV time period showed a direct proportional relationship with failed extubation (p=0.186).Conclusions: The Y/T index is not a good predictor of success of extubation in the study opulation. No association was found between clinical and sociodemographic characteristics of the opulation, with respect to the sensitivity and specificity of the Y/T as a predictor of success.

Authors: Maksimov Aleksandr V. , Klevno Vladimir A. 
Published: December 2019

Aim. To establish signifi cant factors infl uencing the discrepancy of lifetime and postmortem diagnoses and to offer a technique of comparison of diagnoses when carrying out the clinical and anatomical analysis of a lethal outcome.Material and methods. The material for the study was 1420 acts of forensic examination of corpses recorded at the Bureau of forensic medical examination of the Moscow region during the 2014–2018 period. We studied the cases of deaths in hospitals of medical organisations with fi nal clinical diagnoses of the initial causes of death from diseases of the circulatory system (1085), respiratory diseases (157), digestive system (178). An analytical comparison of nosological forms of diseases in all headings of the fi nal clinical and forensic diagnoses was carried out. The frequency of occurrence of objective and subjective causes of discrepancy of diagnoses was determined. The most signifi cant factors of erroneous formulation of the fi nal clinical diagnosis, which create risks in the formation of divergence of diagnoses, were established. The causes of divergence of diagnoses relevant to the choice of inadequate treatment and the onset of death were established. Absolute (abs) values were calculated for qualitative variables and relative (%) frequencies. The frequency comparison was carried out using Fisher’s two-way exact criterion. Risk ratios with 95 % bilateral confi dence intervals for risk ratios were calculated to identify the factors causing the highest level of divergence. Statistically signifi cant differences were considered when the probability of error of the fi rst kind was less than 5 % (p < 0.05). Data processing was carried out using the Excel 2016 (Microsoft, USA) and IBM SPSS Statistics 25 (IBM, USA) software.Results. The study found that the discrepancy between the lifetime diagnosis criteria of reliability, etiopathogenetic and timeliness are the most signifi cant factors affecting the discrepancy of diagnoses under the heading “underlying disease”. The causes of divergence of diagnoses, which are of the greatest importance for the choice of inadequate treatment and the formation of a lethal outcome, were revealed. On the basis of the obtained data, a method for comparing the in vivo and postmortem diagnoses during the clinical and anatomical analysis of the lethal outcome was developed.Conclusion. Incorrect clinical diagnosis is important in the onset of death only if the erroneous diagnosis is due to insuffi cient examination of the patient, the lack of clinical data, the severity of the condition and the short duration of stay, which does not allow the underlying disease and fatal complication to be determined and adequate medical measures to be carried out. The proposed method for comparing the in vivo and postmortem diagnoses allows a correct, reliable and convincing clinical and anatomical analysis of the case of death in the hospital to be performed.

Published: December 2019

Aim. Experimental evaluation of the effect of some cryoprotectors on crystallogenic properties of mice blood serum at intraperitoneal administration.Material and methods. The experiment was performed on 40 adult white line mice divided into 4 equal groups. Animals from the control (fi rst) group received a single intraperitoneal injection of saline (0.5 ml agent/animal), animals of the second-fourth groups — 3 % solution of glycerin, dimethyl sulphoxide and trombocryodmac (N, N-dimethylacetamide), respectively, in the same quantity.Results. It is shown that single intraperitoneal introduction of cryoprotectants (solutions of glycerin, dimethyl sulphoxide and trombocryodmac) has a systemic effect on the mouse organism, which is manifested through the changes of crystallogenic properties of blood serum. 3% solution of glycerin, dimethyl sulphoxide and trombocryodmac have multidirectional infl uence on crystallogenic properties of mouse blood serum. The most pronounced physiological effect was established for dimethyl sulphoxide.Conclusion. Our studies demonstrate the presence of systemic effects in cryopreservative substances. It was confi rmed by the changes of crystallogenic properties of mice blood serum under intraperitoneal administration of cryopreservatives.

Aim. To describe the ultrastructural characteristics of the blood-air barrier (BAB) interstitium in fi brous cavernous pulmonary tuberculosis (FCT) in comparison with chronic nonspecifi c lung diseases (CNSLD).Materials and methods. The fragments of the pericavernal zone and lung tissue were taken for the study at the resection border from the dead or operated for CNSLD persons (n = 163), and the perifocal and boundary zone of lung tissue. 116 CNSLD patients were divided into 3 subgroups: 1) chronic lung abscess (n = 42); 2) bronchiectasis (n = 44); 3) lung cyst (n = 30). The lung fragments of 30 patients who died from pathology not associated with lung diseases (myocardial infarction, acute cerebrovascular accident) were used as a control group to compare the morphological parameters. The criteria for inclusion of patients in the study: age from 18 to 65 years, negative clinical and laboratory data on the presence of comorbid pathology (viral hepatitis B, C and HIV). For TEM, lung fragments 1×1×1 mm in size were cut out and fi xed in a 2.5% glutaraldehyde solution in phosphate buffer (pH = 7.2–7.4) and washed in 0.1 M phosphate buffer (pH = 7.4), followed by dehydration in alcohols of an ascending concentration and placing in a mixture of Epon and Araldite resins according to the scheme. Ultrathin sections were made with Reynolds staining. Viewing and photographing preparations was carried out on a PEM-100 transmission electron microscope (Ukraine) (magnifi cation range from ×1000 to ×30 000). Results. It was established that changes in BAB components in all groups had similar features in the form of severe interstitial fi brosis, the signs of endothelial cell degeneration and destruction of varying degrees of severity, as well as the heterogeneity of the endothelial and epithelial basement membranes.Conclusion. Ultrastructural changes in the BAB components of the removed lung part in patients with FCT and chronic nonspecifi c lung diseases are characterised by a polymorphism with prevailing dystrophic and destructive changes in the perifocal zone of infl ammation, and compensatory-adaptive processes on the peripheral, especially at the resection border.

Published: December 2019

Aim. Clinical, epidemic and laboratory characterisation of ixodic tick-borne borreliosis in order to improve the early diagnosis of the disease and the timely etiotropic therapy.Materials and methods. The medical histories of 257 patients with ixodic tick-borne borreliosis treated in the regional infectious diseases hospital in Krasnodar from 2004 to 2018 were analysed. The data of the epidemiological history, the clinical manifestations of the disease, the results of laboratory and instrumental studies, as well as the principles of therapy were analysed.Results. The incidence of ixodic tick-borne borreliosis in the Krasnodar Krai is characterised by spring-summer seasonality, the predominance among women over 45, and urban residents. The disease has an acute course (85.9%), occurs mainly in the erythema form with little pronounced symptoms of intoxication, a typical ring-shaped erythema, which large dimensions remain longer in women. During the non-erythemic form of the disease, the development of serous meningitis and encephalomeningitis with impaired cerebral blood fl ow as well as the changes in corticocortical relationships were observed. During the sub-acute course, radiculopathy and polyneuropathy, as well as diffuse changes of the myocardium with conduction disturbance and the development of atrioventricular block, arthralgia and arthritis/arthrosis were registered. The increase in LDH, CPK and transaminase was observed for all forms of the disease.Conclusion. In connection with the formation of a natural ixodic tick-borne borreliosis focus on the territory of the Krasnodar Krai, it is necessary to exclude this disease in patients with the signs of fever, weakness, and erythema at the site of tick suction. The tendency of ixodic tickborne borreliosis to the long course with the development of multiorgan pathology causes the need for follow-up observation of recovered patients both by an infectious disease specialist and narrow specialists (a neurologist, rheumatologist or cardiologist).

Aim. To compare the results of surgical treatment using bipolar hemostasis and traditional ligation of ligaments and blood vessels in vaginal hysterectomy.Material and methods. Fifty patients with benign uterine disease underwent vaginal hysterectomy using electrosurgery (n = 29) or conventional suture ligation (n = 21 controls).Results. Postoperative pain (especially on the fi rst day) was decreased in the electrosurgery group (5.50 ± 1.43 VAS points) as compared to the control group (7.64 ± 0.58 points), p < 0.001. Intraoperative blood loss was signifi cantly lower in electrosurgery group (82.86 ± 22.58 ml) than in the control group (226.36 ± 129.12 ml), p < 0.001. Operating time was signifi cantly shorter in the main group than in the controls (65.36 ± 20.9 min vs. 86.59 ± 40.19 min, p < 0.05). On average, 2.75 ± 1.11 suture packages were used with bipolar coagulation, 6.00 ± 1.93 in the controls (p < 0.001). Hospital stay was similar for both groups. Adverse event rates did not differ signifi cantly.Conclusions. Bipolar coagulation with the TissueSeal Plus proved to be more effi cient or identical to traditional suture ligation. Intraoperative blood loss, postoperative pain and the duration of the operation were less, while the complications were identical for both groups. In addition, bipolar coagulation was easier to use and cost effective. These fi ndings prove the feasibility and effectiveness of the use of electrosurgical techniques to perform hysterectomy and its further study

Authors: Agarkova Alina A. , Pokrovsky Mikhail V. , Kolesnichenko Pavel D. 
Published: December 2019

Aim. To study neurological disorders in rats when modeling purulent bacterial meningitis (PBM) on the example of pneumococcal meningitis under experimental conditions.Materials and methods. Pneumococcal meningitis was modeled by injecting a suspension containing Streptococcus pneumoniae at a concentration of 5×109 CFU/ml into the subarachnoid space. The degree of neurological disorders was determined by clinical assessment of rat health status, the degree of neurological defi cit, specifi c strength, “Infrared activity monitor”, “Object recognition task” tests.Results. When modeling pneumococcal meningitis in rats, the sum of points of clinical assessment of their health in the 1st day after modeling the pathology is 34.2 % less than the initial, on the 5th — less than 3.4 %, on the 8th day returns to the primary indicator, 5 points. The maximum degree of severity of neurological defi cit was observed in the fi rst four days after meningitis modeling; it was in the 1st day 34 % less than the same indicator in the group of intact animals, on the 2nd day 32.7 % less, on the 3rd day — 30.7 % and on the 4th day — 30.1 %. In the meningitis group on day 10, the distribution of neurological defi cit by severity was as follows: mild — 32 %, medium — 20 %, severe — 16 %, without residual neurological defi cit — 32 %. The specifi c strength of rats in the group of meningitis on the 1st, 5th and 10th day after the development of the pathology was 48.7, 64, and 67.4 % of the baseline specifi c strength. In relation to intact animals, the index of recognition of short-term memory in rats of the meningitis group is 2.3 times greater, and the index of recognition of long-term memory is 1.7 times greater.Conclusion. The dynamics of neurological disorders in rats in the simulation of PBM can be determined using the methods of assessing behavioural and cognitive status. In rats, when modeling pneumococcal meningitis, neurological disorders are maximally expressed on the 1st day of the disease. Then there is a distinct positive dynamic up to 5 days of the disease. From 6 to 10 days positive dynamics is present, but insignifi cant.

A Decorated Jar of the Byzantine Period in the Museo Egizio, Turin (Suppl. 15626)
Authors: Incordino Ilaria , Facchetti Federica 
Published: December 2019

The article analyses a previously unpublished painted jar from the Byzantine Period discovered by Ernesto Schiaparelli at Asyut, possibly in 1911, and presently kept at the Museo Egizio, Turin (S. 15626). The distinctive female figure represented on the upper half of the body of the vessel is rather rare in the Byzantine repertoire. The author compares it with similar figures found on different supports and in different contexts. Notably, she highlights parallels with painted pottery from the monastery of Abba Nefer the Hermit at Manqabad, as well as in pottery assemblages from Kellia, Saqqara, Esna, Tebtynis, Deir el Bachit (West Thebes), and especially towns in Middle Egypt such as Amarna (Kom el-Nana), El-Ashmunein, Antinoopolis and Wadi Sarga. The probably non-religious female figure may be an instance of the well-known tendency in Byzantine Egypt to draw on the Hellenistic repertoire, especially in depictions of figures of prosperity and good luck, which would have been easily recognizable by both Christians and pagans.

حلل المقالة إناء ملون لم يتم نشره من قبل ويعود إلى العصر البيزنطي، إكتشفه إرنستو سكياباريلي في أسيوط، على الأرجح في عام 1911، محفوظ حالياً في المتحف المصري بتورينو (S. 15626). الشكل الأنثوي المميز المعروض في النصف العلوي من جسم الإناء نادر جداً ضمن مجموعات أعمال العصر البيزنطي. يقارن المؤلف الشكل الموجود على الجزء العلوي من الإناء بأشكال متشابهة موجودة على أدوات مختلفة. تجدر الإشارة إلى أن الشكل يُبرز أوجه التشابه مع الفخار الملون بدير الناسك أبو نفر في منقباد، وكذلك في مجموعات فخارية موجودة في منطقة كيليا وسقارة وإسنا وتبتنيس ودير البشت (غرب طيبة)، وبشكل خاص في مدن مصر الوسطى مثل العمارنة (كوم النعناع) والأشمونين وانطيونوبوليس ووادي سرجة. ربما يكون شكل الشخصية الأنثوية غير الديني مثالاً على النزعة المعروفة في مصر البيزنطية من خلال الإرتكاز على مجموعة أعمال العصر الهلنستي، لا سيما في تصوير أشكال الرخاء والحظ السعيد التي كان يمكن التعرف عليها بسهولة لكلٍ من المسيحيين والوثنيين.
DYSFUNCTIONAL SEMANTIC ROLE OF LANGUAGE IN LITERARY TEXTS: A CASE STUDY ON HAROLD PINTER’S MOUNTAIN LANGUAGE
Authors: Saeed Yadgar Faeq , Muhammed Areen Ahmed 
Published: December 2019

Language and literature are two inseparable subjects, one of which cannot be fully functional with the absence of the second part. This article shows the dysfunction of semantics in Harold Pinter’s Mountain Language. For many years, scholars and linguists work separately on different cases regarding literary texts or linguistics obstacles. From this paper, a new path will be saved for future references and works to bring both cases together and show their roles on one another. Moreover, literary works pay less attention to grammatical rules and plenty of dysfunctional languages can be examined and seen. In addition, several external factors can be the obstacle of using functional and accurate language use semantically and systematically. Moreover, political or social violence have become major points in many literary topics in the modern era. This study deals with theoretical aspects of society starting from family up to community and government. Additionally, the absence of semantics in the language of this drama is not neglected arbitrarily; whilst, there is a loop of violence. There are some basic theories related to the topic that this paper will examine. It includes the theory of Grice’s maxims (Gricean maxims) and the role of semantics when it comes to politics and power. Finally, the paper alienates all the curtains and shows the role of power, gender differences, class status, and diversity on language use in many areas.

Published: December 2019

<p>Trabajo Final de Graduación para optar por el título de Ingeniera Agrónoma</p><p>La relación insecto-planta es interesante de conocer, por cuanto nos revela las preferencias alimenticias de la abeja. El polen es la principal fuente de proteínas y lípidos para las abejas, es recogido con gran intensidad en el período primaveral para elaborar el “pan de las abejas” coincidiendo con el desarrollo de las larvas y el crecimiento de la colonia. El objetivo general de este trabajo fue conocer la variabilidad florística de las cargas polínicas aprovechadas por Apis mellifera en la localidad de General Pinedo, provincia del Chaco. Las muestras fueron tomadas semanalmente en el periodo apícola 2014 - 2015, se utilizaron trampas caza-polen colocadas en la entrada de 3 (tres) colmenas. Se procesaron, con la técnica de acetólisis, 18 muestras en total. Cada muestra fue pesada y luego fue deshidratada por el método de liofilizado para su conservación. Posteriormente, las muestras fueron separadas y clasificadas por color en 66 submuestras. Todas las observaciones, descripciones y análisis se realizaron con microscopio óptico Leica CME y se obtuvieron fotografías digitales de los granos de polen con la cámara Leica ICC50W del equipo Leica DM500 y con microscopio electrónico de barrido JEOL 5800LV. Algunas cargas corbiculares fueron seleccionadas para evaluar su contenido de nitrógeno y proteína total mediante el Método Kjeldahl. Los resultados obtenidos fueron sometidos a análisis descriptivos y multivariados. Se realizaron análisis de componentes principales (PCA) y análisis de agrupamiento, utilizando distancia de Jaccard y el algoritmo UPGMA para la elaboración del dendrograma. Los resultados obtenidos mostraron que las preferencias de Apis estuvo representada por 31 taxa, de los cuales se identificaron 23 a nivel específico, 5 a nivel genérico, 2 a tipo polínico y 1 no pudo ser determinado taxonómicamente. Las familias vegetales identificadas fueron 18, las Fabaceae y Asteraceae fueron las mejor representadas en número de especies, en coincidencia con otras regiones fitogeográficas del país. El 81% son especies nativas y el 19% son exóticas. Los estudios de contenido proteico de las cargas corbiculares realizados en este trabajo aportan información acerca de la capacidad nutricional de las especies nativas. Finalmente, a partir de los resultados obtenidos resulta interesante y necesario continuar con estudios de esta temática para conocer detalladamente</p><p>las propiedades nutricionales del polen que disponen las abejas de esta región.</p>
