Authors: Kosova Ye. A. , Gapon A. S. , Redkokosh K. I.
Published: December 2021

The purpose of the article is to assess the accessibility of electronic educational resources (EER) published in the university Moodle Learning Management System (LMS). The analysis involved 22 EERs in mathematical and information technology disciplines, located in the Moodle LMS of the V. I. Vernadsky Crimean Federal University. The examination algorithm included analysis using the Web Accessibility Evaluation Tool (WAVE) and expert analysis of web accessibility using visual, auditory and manual methods based on 89 checklist attributes. In the result of the analysis, multiple accessibility errors of the Moodle platform and the EERs hosted on it were found. The most serious platform problems include: lack of compatibility with text browsers; errors of reproduction by screen readers; errors of content reproduction on mobile devices. The list of accessibility errors made by the authors of EERs includes: incorrect design of hyperlinks (22.7 % of the EERs); lack of subtitles (13.6 %), transcripts (22.7 %), synopses of video lectures (27.3 %); lack of alternative descriptions for figures (68.2 %); time limit for tests (9.1 %); lack of special markup for mathematical notation (36.4 %) and program code (13.6 %), etc. Results of the survey show need in training of EERs’ authors in technologies for developing accessible educational web content. It is advisable to familiarize web developers deploying an LMS at universities with the basics of web accessibility, LMS accessibility functions and modules in order to select the most suitable platform, determine and install the required set of accessibility tools. Before launching all EERs should be subject to mandatory examination for compliance with the web accessibility guidelines.

COVID-19 pandemisinin küresel boyutta olmak üzere ekonomik, sosyal, halk sağlığı ve toplumsal birçok açıdan olumsuz sonuçları bulunmaktadır. Etkileri bu denli geniş olan pandeminin yalnızca sağlık boyutu ile ele alınması yetersizdir. Pandemi bir biyolojik kaynaklı afettir ve günümüz afet risk yönetimi sürecinin tüm aşamaları ile dirençlilik perspektifinden değerlendirilmelidir. Bu çalışma, pandemi ve afet ilişkisini ortaya koyarak pandemi sürecinde ülkemizdeki durumun afet yönetimi sürecine özgü değerlendirilmesini ve pandemi süreçlerinde afet risk azaltma ve dirençlilik kapsamında ele alınabilecek uygulamaları afet yönetiminin süreçlerine göre planlamayı ve tartışmayı amaçlamaktadır. Olay komuta yönetimi ve operasyon servisi Sağlık Bakanlığı olmak üzere, kurumsal düzenlemeler noktasında biyolojik afetlerde özellikle AFAD’ın da dahil olduğu koordinasyon düzeninde dirençlilik yaklaşımı benimsenmesi önerilmektedir. Sağlık Bakanlığı’nın mevcut pandemi planları dirençlilik bakış açısı ile ele alınmalıdır.

Published: December 2021

Introduction: Critical thinking dispositions (CTD) are valued across the health professions disciplines being essential for decision-making, critical judgment and managing complex health situations. Promoting critical-thinking dispositions in undergraduate nursing students can support the students to utilize critical thinking during challenging patient care and problem-solving situations.

Objective: This study aimed to assess the level of critical thinking disposition among neophyte nursing students in a private nursing college.

Methodology: An analytical cross-sectional study design was adopted. Neophyte students (n=98) of the BSN program participated in the study. Critical Thinking Dispositions Scale (CTDS) of 54 items under seven constructs was utilized to assess CTD level. Data was analyzed at descriptive and inferential level using SPSS 23.0 version. 

Results: Overall, CTD among neophytes nursing students is at 75% a progressive level. Contextual and inquisitiveness construct of CTDs are at positive CTD level while other constructs are at the progressive level. Students have completed their matriculation from public 55(56.1%) while FSc (Faculty of Science) from private sector 57(58.2%). Mothers of most neophytes 73(74.5%) were housewives and fathers were working in private organization 32(32.7%). There was no statistically significant association between CTD’s construct with demographic variables (P-Value, >0.05). FSc marks showed a significant association with overall CTD scores, intellectual and inquisitiveness, while admission entry test scores associate significantly with intellectual construct.

Conclusion: The CTD level of neophyte is at a progressive level which suggest that different teaching and learning strategies could be implemented to improve this level.

Background: Determining the cause of death among drug addicts in Residential Rehab Campuses (RRCs) is of paramount importance, since it may prevent and reduce morbidity and mortality rates. Therefore, the present study was done to investigate the cause of death among drug addicts in RRCs in Kahrizak Dissection Hall, Tehran Province, Iran, from September 2011 to September 2019. Methods: In this descriptive cross-sectional study, a total number of 166 drug addicts, who had died in the RRCs located in Tehran, Iran were examined, and the findings were analyzed using the SPSS v. 26. Moreover, the Chi-square test was utilized to compare the results. Results: In this study, the most important causes of death, were infections, drug side effects, Myocardial Infarction (MI), and drowning, respectively. The highest frequency of death had occurred in the 31-40-year-old age group and was mostly observed in unmarried individuals. The most common causes of death were infection among the single and divorced ones and were MI for married cases. Toxicological results were generally negative in 60.84% of the cases. Also, 86.74% of the cases were non-pathological with regard to the brain tissue samples and 65.66% of the individuals had no pathological cardiac lesions. Besides, the most common microscopic findings of the lungs were associated with pulmonary edema. In the trauma group and also drug side effects and drowning groups, the most frequent pathological findings were pulmonary hemorrhage and pulmonary edema, respectively. As a whole, 69.87% of the deaths had occurred in the RRCs and 55.42% of them were assumed natural in terms of mode of occurrence. Conclusion: The majority of the deaths in the RRCs should not have occurred if the given centers were authorized and the illegal centers were closed. Moreover, these centers should have proper management with the presence of resident physicians and trained medical staff as well as necessary medical equipment, proper nutrition, no access to drugs and other illicit substances, along with adherence to hygienic principles to minimize mortality rates among the drug addicts living in the RRCs.

Authors:   Department of Audiology, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran., Jalilzadeh Afshar Parisa
Published: December 2021

A 56-year-old female with dizziness, imbalance, and a slight floating sensation was evaluated. Her symptoms started after infection with the novel coronavirus (SARS-CoV-2). Routine auditory test (pure tone audiometry), vestibular assessment (videonystagmography), and neurologic test results were in the normal range, but the otolith evaluations, such as cervical vestibular evoked myogenic potentials (cVEMP) and subjective visual vertical tests, showed abnormal findings. The patient underwent a ten-session individualized vestibular rehabilitation program (one session per week). After completing rehabilitation sessions, her chief complaints were alleviated, the performance on computerized posturography was improved, and the abnormal cVEMP amplitude asymmetry between ears disappeared. In conclusion, vestibular disorders can happen after COVID-19 infection, presenting exclusively with isolated otolith dysfunction. In these patients, functional integrity assessment of the whole vestibular system is crucial, and vestibular rehabilitation may be beneficial.
Актуалізацыя прагматычнай інтэнцыі моўцы ў гутарковым маўленні (на матэрыяле гаворак паўночна-заходняй Беларусі і яе пагранічча)
Authors: Маліцкі Юрый
Published: December 2021

Until recently, in the study of the pragmatic means of language, linguists’ research interest has been focused mainly on units of the lexical level. Meanwhile, in the real flow of speech (in communication between people in everyday and professional situations) the word is invariably accompanied by means that actua¬lize its content, emphasize and strengthen it, highlighting it against other contents. Thus, there are important elements beyond the actual lexical level of language. Exploring ways to actualize pragmatic content in conversational communication is a new and promising area of linguistic research. The analysis of the formal side of the actualization of the corresponding intention of the speaker seems especially interesting and fruitful in a multilingual situation, so the dialects of North-Western Belarus and its border are extremely interesting from a research point of view.

About thirty Belarusian-language texts of the Uprising of 1863 have survived up to this day. Our interest lay, first of all, in the history of these works, the problems of their textual analysis, as well as their attribution. We closely looked at all known and available lists of their publishers. This concerns the Conversation (Hutarka) of an Old Man, twenty-two lists of which (nineteen Belarusian, one Lithuanian and one Russian) have recently been published in a specialised book by Tomas Nastulchik. We used photocopies from T. Nastulchik’s book as well as originals (or microfilms) from archival files, tried to identify the protograph of the Conversation..., or rather, the author's version of the work. As a result, we came to the conclusion that the preserved lists can be divided into five groups (some of which include two, three or four edited versions of the text). This may mean that, on the basis of the author's version, no less than five lists appeared, the scribes of which were in fact editors or even co-authors of our poet. We believe that some of the earliest, and thus the closest to the protograph, are the lists of the so-called “lithographed” groups. We did not raise the question of authorship due to the lack of necessary material, but we believe that the presence of a significant number of verbs with an infinitive postfix- “ci” in the lists of the “lithographed” and “Poznań-Lviv” groups directs our efforts to find the author among speakers of the Volkovysk-Bialystok dialect of the Belarusian language. Of course, K. Kalinouski may not be the author, but the significant similarity of the Conversation… and the “Muzhytskaya Prauda” in many aspects of its ideological and artistic content allows us to look for the poet in the circle of his closest associates, both among the students of the St. Petersburg-Moscow youth and the Grodno insurgent organi-zation. We considered it necessary to include Lithuanian-language versions of the Conversation… in our publication since we believe that the problem of attribution of the Belarusian work is closely connected to the Lithuanian text.

Authors: Bastias G. Magdalena , Villena M. Rodolfo , Dunstan E. Jocelyn , Zanolli S. Mario
Published: December 2021

Existe un aumento epidémico de miopía en distintas partes del mundo. En niños, la evidencia apunta hacia la falta de exposición a luz natural. En Chile, la situación poblacional de miopía en niños se desconoce.Objetivo: Estimar la tendencia de miopía y astigmatismo miópico en escolares de 1º y 6º básico del sistema público de educación de Chile.Sujetos y Método: Estudio ecológico en base a las confirmaciones diagnósticas del Programa Servicios Médicos de JUNAEB, periodo 2012-2018. Se estimó prevalencia anual de miopía y astigmatismo del país, por región y según sexo. La evaluación en el tamizaje contempló agudeza visual usando tabla Snellen E Abreviada, rojo pupilar, test de Hirschberg, test de Titmus, Cover test, motilidad ocular y examen de segmento anterior. Se utilizó chi2 y regresión logística para evaluar diferencias y regresión lineal para estimar cambio promedio anual.Resultados: En 2012-2018, la miopía y astigmatismo miópico tuvieron presentación geográfica heterogénea. La miopía y astigmatismo miópico ≥ 3 dioptrías aumentaron a un promedio anual de 0,11% (R2 0,67) y 1,21% (R2 0,90) en 1º básico y a 0,2% (R2 0,65) y 8,7% (R2 0,79) en 6º básico. La miopía < 3 dioptrías declinó 0,13% promedio anual (R2 0,45) en 1º básico y el astigmatismo miópico < 3 dioptrías, 0,5% (R2 0,53) en 6º básico. El astigmatismo miópico alto afectó más a hombres y la miopía < 3 dioptrías a mujeres de 6º básico.Discusión: En los escolares del sistema público de educación, la miopía y astigmatismo miópico ≥ 3 dioptrías tienden al aumento. El efecto protector de miopía que otorga la luz natural, demostrado en estudios longitudinales y experimentales, es evidencia a considerar para fomentar el tiempo de los niños al aire libre.

Published: December 2021

Las vasculitis asociadas a ANCA (AAV) son enfermedades infrecuentes en la edad pediátrica. La literatura internacional en pediatría es escasa y la mayoría de las publicaciones se refieren a otras vasculitis de mayor incidencia en la infancia, como la vasculitis IgA y enfermedad de Kawasaki.Objetivo: Describir las características clínicas y de laboratorio de una serie de pacientes pediátricos con diagnóstico de AAV.Pacientes y Método: Estudio retrospectivo, descriptivo, de pacientes con diagnóstico de AAV atendidos en un centro terciario de salud en Santiago, Chile, entre los años 2000 y 2020. Se revisaron fichas electrónicas recolectando datos epidemiológicos, de laboratorio, imágenes y biopsias.Resultados: Se presentan cinco pacientes pediátricos con AAV de severidad variable, rango de edad al debut 5,5 a 13,5 años. Destaca una frecuencia elevada de compromiso renal en casos de poliangeítis microscópica (MPA) y el compromiso orbitario de tipo pseudotumor inflamatorio en pacientes con granulomatosis con poliangeítis (GPA); manifestación poco frecuente en series pediátricas internacionales. Los pacientes fueron tratados según recomendaciones extrapoladas de ensayos clínicos en población adulta con respuesta clínica satisfactoria; en su mayoría con corticoides sistémicos y ciclofosfamida o rituximab en etapa de inducción. Durante la mantención, la mayoría de pacientes se mantuvo estable con rituximab, azatioprina o metotrexato. Ningún paciente evolucionó con secuelas en órganos afectados y todos lograron suspender la terapia corticoidal.Conclusión: El presente reporte describe las características clínicas de una serie de pacientes pediátricos con AAV. En esta serie, la afectación renal fue frecuente en MPA y la afectación ocular por pseudotumor inflamatorio en GPA. La respuesta clínica con tratamiento según recomendaciones extrapoladas de población adulta fue favorable.

Efficacy and safety of levilimab, a monoclonal antibody to interleukin-6 receptors, in patients with rheumatoid arthritis
Authors: Novikov P. , Shchegoleva E. , Moiseev S.
Published: December 2021

Interleukin (IL)-6 is a proinlammatory cytokine contributing significantly to the pathogenesis of joint disease and systemic manifestations of rheumatoid arthritis (RA). Levilimab is a new original monoclonal antibody that blocks both soluble and membrane-bound IL-6 receptors. Efficacy and favorable safety profile of levilimab in combination with methotrexate were shown in two randomized double-blind placebo-controlled trials (AURORA and SOLAR) that included patients with active RA despite treatment with methotrexate alone. Both primary and multiple secondary efficacy endpoints including ACR response, low disease activity or remission rates, changes in RA activity scores, etc, confirmed a higher efficacy of levilimab compared to placebo. Profile of adverse events was typical for IL-inhibitors. Several observational studies suggested that unlike rituximab or medium or high dose glucocorticoids IL-6 receptors inhibitors do not worsen outcomes of COVID19 and do not impair immunogenicity of vaccines against COVID-19. Therefore, patients treated with levilimab should not delay vaccination or modify the dosing regimen prior to vaccination.
ПЕРСПЕКТИВНІ СТАРТОВІ КУЛЬТУРИ ДЛЯ КРАФТОВИХ КОВБАСНИХ ВИРОБІВ
Authors: Шинкарук М.В. , Балук О.О.
Published: December 2021

У статті досліджено проблему поліпшення якості сиров’ялених м’ясних продуктів за допомогою використання стартових культур. У технології м’ясних продуктів визначається тенденція до використання рослинних харчових добавок у поєднанні зі стартовими культурами для поліпшення якості готової продукції. Важливою властивістю є антагонізм – придушення зростання мікроорганізмів, що спричинюють псування продукту. Для відтворення кольору м’ясопродуктів у складі стартових культур повинні бути денітрифікуючі бактерії. До основних технологічних властивостей стартових культур можна віднести зброджування вуглеводів із утворенням молочної кислоти, скорочування часу дозрівання, збільшення виходу готового продукту та подовження термінів зберігання. В разі додавання пропіонових бактерій істотно покращуються структурно-механічні властивості продукту, забезпечується зменшення втрат за теплової обробки, підвищується вологозв’язувальна здатність, що позитивно позначається на якості готового продукту. Молочнокислі бактерії є біологічною основою формування ковбаси як харчового продукту, завдяки ним відбувається біологічне перетворення основних компонентів м’яса з утворенням сполук, що зумовлюють смак та аромат, консистенцію; зміна фізико-хімічних параметрів м’ясного фаршу може призвести до розвитку мікробів, здатних викликати псування м’яса. Застосування стартових культур у виробництві м’ясних продуктів забезпечує не лише скорочення часу технологічного процесу, а й гарантує мікробіологічну безпеку готової продукції. Таким чином, бактеріальні закваски є найважливішим фактором формування якості м’ясних виробів. Правильно підібрані культури у заквасці сприяють не тільки формуванню приємного смаку та аромату продукту, стабілізації забарвлення, а й придушенню життєдіяльності гнильних та санітарно-показових бактерій. Крім того, встановлено, що деякі мікроорганізми мають протеолітичну активність, внутрішньоклітинні ферменти, які здатні розщеплювати білки м’яса, таким чином покращуючи структурні характеристики готового продукту. А деякі стартові культури можуть виступати в ролі антиоксидантів, перешкоджаючи окисленню жиру в ковбасних виробах.
Predicting Big Five Model Personality Traits in Recent Social Context
Authors: Md. Mahfuzur Rahman Khan
Published: December 2021

The theory of the five great factors of personality (Big Five theory) is currently considered to be the best at explaining the most individual variability in terms of personality factors between subjects. The purpose of this study is to examine the relationship between the Big Five personality traits and the recent social context, and to determine whether social support can act as a moderating factor in the process. While previous research has established that personality traits are significant predictors of well-being, the extent to which the big five personality traits influence social well-being remains unknown. This research paper employs a qualitative method based on a deductive research approach, as the author used deductive logic to predict the big five model personality traits in a recent social context. Five personality traits were found to be significantly related to the overall social context and social support functions as a determinant in the relationships between extraversion/agreeableness/conscientiousness/neuroticism/openness and social context. Numerous studies now concur, and there is a high degree of consensus in the literature regarding the Big Five theory as a useful theory for identifying and describing the major general factors of personality.

The sample consisted of 849 pre-service teachers of different majors. Data were collected, using the Physics Anxiety Rating Scale (PARS) at the beginning of the semester. Post-semester data were obtained from 175 pre-service teachers who were included in the pre-semester data. Results revealed gender difference in physics anxiety. Females scored higher on the PARS and its factors than males. It was found that students with medium GPA scored lower on the whole anxiety scale than students with low and high GPA. Pre-service primary teachers scored higher on the PARS than all other majors. High school type had an effect on physics anxiety, vocational high school graduates being the highest physics anxious of all. One semester of traditional physics instruction did not seem to have a significant influence on students’ physics anxiety. Implications of the results were discussed for instructional purposes and future studies. Key words: demographic variable, physics, physics anxiety rating scale, science anxiety.

Purpose. Substantiation of the conditions for haulage drifts stability using different protection methods in steeply dipping seams based on a set of experimental studies. Methods. To achieve the purpose set, mine instrumental observations have been performed to study the rock pressure manifestations in zonal advance workings adjacent to the stope face on the haulage horizon. The conditions for their maintenance, within the mining site, are assessed by the side rocks convergence value on the drift contour and the change in the cross-sectional area, taking into account the deformation properties of the protective structures. Findings. It is recorded that in the zone of the stope works influence, in the most difficult conditions, haulage drifts are maintained, when coal pillars or clumps of prop stays are used for their protection. It has been determined that a decrease in the section of such mine workings up to 50% is the result of the protective structures destruction. When protecting the hau-lage drifts with the rolling-on chocks, a decrease in the mine working section up to 30% occurs in the process of the protective structures compression. It has been revealed that deformation of coal pillars or clumps of prop stays up to 10-20% leads to a loss of their stability, and an increase to 60% leads to a complete loss of their load-bearing capacity, intensification of rock displacements on the mine working contour and deterioration of its stability. It has been determined that in the process of deformation of the rolling-on chocks from sleepers by 20-60%, they are compressed without loss of load-bearing capacity, which ensures a smooth deflection of the overhanging stratum and restriction of rock displacements on the haulage drift contour. Originality. To study the deformation characteristics of protective structures above the drift, the function of the increment is used of side rock displacements on the haulage drift contour along the mining site length dependent on the relative deformations of protective structures, which makes it possible to assess the real dynamics of the process. Practical implications. When mining steep coal seams, using the specificity of geomechanical processes, which are manifested in an anisotropic coal-rock mass during unloading, satisfactory mine workings stability can be ensured by changing the deformation properties of protective structures above the drift.

Purpose. Although the hydrocyclone separator has many advantages, it still has some limitations which decrease its separation efficiency in many mineral processing applications because of fine particles which are miss separated to the coarse product in the underflow. Water injection in the conical part of the cyclone was recently implemented to solve this problem. The water injection mechanism and the way in which the injected water affects the separation are still not clear and need to be more investigated. Methods. New design of water injection hydrocyclone was tried using a modified conical part with a water injection range consist of five equal distance injection openings open directly on the periphery of the cone part. Findings. This study presents a mechanical mathematical model that simulates the water injection to give a clear indication of the injection mechanism impact on the classification process. It could also predict the dependence of the basic characteristics of the classification on the amount of the injected water and the influence of different operating and design parameters of the hydrocyclone. Originality. The model accounts for the fluid flow, the particle motion, the turbulent particle diffusion, and particle settling. Particle interactions and fine particle entrainment by settling coarse particles are also included in the model. The model was found to predict well the injection effect and agrees with the experimental results. Practical implications. The results showed also that the increase in water injection velocity leads to an increase in both the cut size and the minimal value of the separation curve. It was found also that the hydrocyclone length has an important effect on the injection process, and the separation sharpness is directly proportional to it at higher values of water injection velocity.

Purpose. Determination of the granulometric characteristics and loosening coefficient of mine rocks formed during stope operations from undercutting the bottom rocks as a potential backfill material based on a set of mine and laboratory research. Methods. To do research, a complex methodology is used, which includes a photographic surveying the mass of destroyed rocks from undercutting the bottom rocks in mine conditions, digital processing and determining the granulometric composition in the software package, sampling the mine rocks at the surface complex, and reconstructing the granulometric composition, similar to the full-scale mine conditions in the laboratory. Sieve analysis, laboratory balance and laboratory container are used to determine the granulometric composition and loosening coefficient. Findings. The dependence between the granulometric composition and loosening coefficient of rocks, which increases by 33% within fractions of 0-50 mm and by 8% within fractions of 50-140 mm, has been revealed. It has been determined that the destroyed rocks in the face within fractions of 0-140 mm have a bulk density of 1.28 g/cm3, loosening coefficient of 1.7, the voidness of and the maximum reserve for the backfill mass compaction with mine rocks is 41.9%. An analytical assessment of the volumes of the formed cavities of the mined-out area in the longwall face and gobed mine workings, as well as the prospects and completeness of their filling with mine rocks have been performed. Originality. It has been determined that the loosening coefficient of mine rocks destroyed in the stope face by KA-200 shearer changes according to the logarithmic dependence on their granulometric composition. This makes it possible to control the granulometric characteristics of the backfill material to achieve the maximum density of the backfill mass. Practical implications. Further research can serve as a basis for determining the rational parameters for the formation and placement of backfill masses during complex-mechanized selective mining of coal seams using various methods of backfilling operations.
Therapeutic Modulation of Brain Temperature: Relevance of Hypothermia to Inflammatory Changes following Transient Cerebral Ischemia in Rats
Authors: Islam Nadira , Aftabuddin Mohammad
Published: December 2021

Background : In stroke, the ischemic crisis activates a series of events, including the inflammatory reactions that are potentiated by reperfusion, eventually leading to neuronal damage. Mild hypothermia has been considered to have a protective effect during ischemic neuronal cell death. The chief aim in this study was to investigate whether changing temperature during and after ischemia could minimize this damage by reducing the inflammatory injury.

Material and Methods: The effect of moderate whole body hypothermia (300 C) on transient focal cerebral ischemia induced inflammatory injury was investigated. Experimental stroke (transient focal cerebral ischemia) was induced by a 2-hour middle cerebral artery occlusion (MCAO) with the use of a suture inserting into the lumen of the internal carotid artery (ICA) in male Wistar rats. Histopathological evaluation was performed 96 h after reperfusion.

Results: MCAO induced inflammatory injury, involving the ipsilateral cortex and basal ganglia with massive infiltration of neutrophils, macrophages and microvascular proliferation, was exhibited in all normothermic rats. However, hypothermic MCAO rats showed minimal inflammatory response.

Conclusion: The present study provides experimental evidence for the beneficial role of mild hypothermia using reversible MCAO in rats. Our results indicate that moderate hypothermia has a significant protective effect on the inflammatory injury induced by transient focal cerebral ischemia. Perhaps, the therapeutic effect was related to a reduction in releasing of cytotoxic products and improvement of the cerebral microcirculation.

Background and Aims: Diabetes mellitus and dyslipidemia, in particular triglyceridemia pose independent risk factors of stroke. Hypertriglyceridemia implicated in the pathogenesis of ischemic stroke by imparting endothelial dysfunction, oxidative stress and lowering fibrinolytic activity. This study was aimed to explore risk incurred by blood triglyceride level for ischemic stroke in type 2 diabetic patients.

Materials and Methods: A total number of 80 [50 with acute ischemic stroke and 30 without stroke] type 2 diabetic patients consecutively admitted in the neurology department, during the period of April to September 2012, fulfilling the recruitment criteria were included in the study. Ischemic stroke was confirmed by CT-scan. Informed written consent from the legal attendant of each patient was obtained. Data regarding clinicobiochemical and images studies were retrieved from patient’s record form.

Results: Male to female ratio was 1.2:1 of the study subjects. Mean (±SD) age (yrs) was 61.0±10.6 in patients with ischemic stroke (Group I) and 57.0±12.3 in patients without stroke (Group II). Risk factors like BMI, lifestyle, smoking, alcohol intake did not show any statistical significance with incidence of ischemic stroke. Mean (±SD) triglyceride (mg/ dl) was 241±56 and 217±102 in Group I and Group II respectively (p=0.024). Eighty eight percent patients had triglyceride 150 mg/dl in Group I and 70 percent in Group II. Triglyceride level (mean±SD, mg/dl) was significantly higher (335±101) in overweightobese patients (BMI 25 Kg/m2) compared to those (232±68) with normal body weight (BMI<25 Kg/m2). Triglyceride level did not show statistical difference among patients having habit of smoking or not. Mean (±SD) cholesterol (mg/dl, (±SD) was 197±62 and 165±26 in Group I and Group II respectively (p=0.009). Mean (±SD) LDL-c (mg/dl) was 101±45 and 98±42 in Group I (43.8±34.4) compared to Group II (60.2±15.6) (p=0.017). Patients with atherosclerotic changes had significantly higher triglyceride (mean±SD, mg/dl) level (338±155) compared to those without (228±89) (p=0.047).

Conclusions: Data concluded that hypertriglyceridemia is relatively common among the diabetic patients even in patients with apparently good glycemic control and possibly incur added risk for ischemic stroke in these patients. However, further studies are needed involving optimum number of patients to substantiate this finding and conclusively comment on the issue and to design effective prevention program to reduce the cerebrovascular morbidity and mortality.
