Predictors, severity and associate factors of acute pancreatitis: A tertiary hospital’s experience
No full textAim: Acute pancreatitis is a common disorder that occurs following an acute response to a pancreatic injury. The aim of this study was to assess predictors of severity and associated factors, as well as the association of different classification systems of severity among pa-tients with acute pancreatitis (AP).Methods: A retrospective case series study was conducted in Albania including 150 patients with AP between March 2021 and March 2022. Variables such as baseline characteristics, la-boratory findings, and calculated scores of known severity classifications were analyzed. Pa-tients were graded as having mild, moderate, or severe acute pancreatitis based on the Revi-sion of the Atlanta Classification (RAC). Ordinal logistic regression was used to model the relationship between the ordinal variable (RAC categories) and the explanatory variables men-tioned above.Results: Women with AP had a higher average age than men with AP (62.5 vs. 57.5 years old, respectively, p<0.05). Additionally, the alcoholic etiology in males prevailed in 100% of cases, while the biliary etiology was more common in females (64.2% compared to 35.8% in males, p<0.001). Ordinal logistic regression showed that a one unit increase in the CT Severi-ty Index (CTSI) and Bedside Index for Severity in Acute Pancreatitis resulted in a 0.968 and 0.430 times increase, respectively, in the ordered log-odds of being in a higher RAC classifi-cation category. The presence of Systemic Inflammatory Response Syndrome (SIRS) (vs. non-present) resulted in a 2.98 higher ordered logit. Conversely, a one unit increase in satura-tion level decreased the ordered log-odds by approximately 0.4 times.Conclusion: The severity of acute pancreatitis is a medical event that requires accurate pre-diction, for which many classification systems have been compiled, with the RAC being the most recent consensus. CTSI, the presence of SIRS, and saturation levels are significantly as-sociated with RAC, without excluding the discussion on the predictive value of laboratory findings, such as glycemia, azotemia, and creatinine
Waist Circumference, a Predictive Factor for Cardiovascular Disease; Our Experience
No full textBackground. Obesity worsens the prognosis of diabetic patients by increasing the cardiovascular risk and chronic complications. The aim of the study was to report the prevalence of waist circumference in individuals with diabetes and find out their association with other cardiovascular risk factors. Material and Methods We performed a transversal study, in which 100 patients with essential hypertension, and type 2 diabetes, were evaluated in comparison with 100 patients with only hypertension. We evaluate these patients for body mass index (BMI), waist circumference (WC); intimae media thickness (IMT); microalbuminuria; fundus oculi. Results. A total of 200 hypertensive patients were enrolled in the study. The diabetic hypertensive subjects significantly had higher BMI (p= 0.01) and WC statistically significant (103.6 cm vs 98.3 cm; P = 0.005). There was a significant positive association between WC and microalbuminuria (P = 0.009); WC and IMT (P= 0.028); 84% of patients with abdominal obesity have changes of diabetic retinopathy independently of the stage of changes. Conclusions. Prevalence of obesity in diabetic hypertensive patients was high. There was a positive relation of waist circumference and microalbuminuria, IMT, and diabetic retinopathy. This underlines the importance of measuring waist circumference when assessing cardiovascular risk factors in diabetic patients.Keywords: Abdominal obesity, organ damage, cardiovascular risk
Assessment of knowledge, attitudes and practices about public health nutrition among students of the University of Medicine in Tirana, Albania
No full textAim: the aim of this survey was twofold: (i): to assess medical students’ knowledge, attitudes and practices regarding nutrition in general, in order to identify their level of competences in the field of nutrition which will be useful in their future role of providers/health care professionals, and; (ii) to assess the knowledge, attitudes and practices regarding the discipline of public health nutrition in order to identify the needs for improving the curriculum of this subject in all the branches of the University of Medicine in Tirana.Methods: A cross-sectional study was conducted in June-July 2013 including a representative sample of 347 students at the University of Medicine in Tirana, Albania (61% females and 39% males; overall mean age: 23±2 years; response rate: 87%). A nutritional questionnaire, adopted according to the models used in previous international studies, was used to assess the level of knowledge, attitudes and practices among the university students.Results: Overall, about one third of the students was not satisfied with the quality and quantity of nutritional education and demanded a more scientifically rigorous curriculum. In general, students’ knowledge about infant feeding practices was adequate. However, there were gaps in the students’ knowledge regarding the commencement of breastfeeding, or the duration of exclusive breast-feeding. Furthermore, there was evidence of an insufficient level of knowledge among students regarding diet and nutrition in general and their health impact, especially on development and prevention of chronic diseases.Conclusion: This survey identified significant gaps in the current curriculum of public health nutrition at the University of Medicine in Tirana. Our findings suggest the need for intervention programs to improve both the quantitative and the qualitative aspects of nutrition curricula in all the branches of the University of Medicine Tirana, in accordance with the professional expectations of this teaching institution, as well as the urge for a movement towards a more integrated curriculum and problem-based learning approach

No full textCharacter as social semiotic in Wole Soyinka’s The lion and the jewel
No full textSemiotics is context bound. Therefore, it is appropriate to situate the locale of any interpretation of art as veritable vehicle for proper understanding. In this regard, Wole Soyinka’s The Lion and the Jewel as a dramatic text derives a better metaphorical essence when assessed as a semiotic correlative of the socio-political conditions in the Nigerian post-colonial experience. Beyond its engagement in the dramatization of events that constitute narrative, character plays a pivotal role as a means by which thematic concerns can be mirrored. In other words, in all ramifications of its application, character usually plays representative roles, especially considering the fact that fiction aims at reflecting what is obtainable, probable or conceivable in a given context. Relating the dramatic events that played out in the text, it is observed that The Lion and the Jewel in its characterization captures a proper representation of socio-political personalities in Nigeria, including the author, Soyinka. From the jewel of contest which is the political power to the predatory turncoats who plunder and rape the patrimony, the drama demonstrates how character can assume a mimetic essence that indicates prophetic act. Just as it is common practice to tag an overbearing political leader the Orwellian Big Brother, and considering how the drama has succeeded to relate or relay sociopolitical identities, it is duly recommended that examination of characters in literature, especially African literature, should account for their roles as counterpart identities of politically exposed persons. Thus, there is a Baroka in the politician who snatches power by unorthodox means; a Lakunle in the upstart whose feeble attempt to contest political power is laughable and a Sadiku who is an accomplice in spite of being a victim
Урбанистичко-архитектонски и симболички осврт на меморијално-споменичко наслеђе Косова и Метохије у делима Светомира Арсића Басаре
No full textПредмет рада представља просторно, урбанистичко-архитектонско и симболичко тумачење споменика НОБ-а на Косову и Метохији, аутора Светомира Арсића Басаре. За анализу су изабрани Споменик народним херојима Борису Вукмировићу и Рамизу Садику и Споменик шарпланинском партизанском одреду. Циљ рада је да се, кроз тумачење принципа просторне перцепције споменика, утврде односи између скулптурне форме и човека, али и основне урбанистичко-архитектонске и споменичке релације, карактеристике, поруке и значења.
За потребе овог истраживања су прикупљени подаци о доступној архивској грађи и постојећем стању споменика, спроведен је интервју са Светомиром Арсићем Басаром, аутором споменика, а потом је извршено урбанистичко-архитектонско и симболичко тумачење споменика.
У раду су дати историјски осврт, преглед друштвених прилика и односа, као и ауторских процеса у урбанистичко-архитектонском конципирању решења, стога овај рад може допринети проширавању досадашњег скромног знања о урбанистичко-архитектонским карактеристикама споменика и бољем разумевању њихове меморијалне симболике.The subject of the paper is a spatial, urban-architectural, and symbolic interpretation of the monuments of the National Liberation War in Kosovo and Metohija, by Svetomir Arsić Basara. The Monument to People’s Heroes Boris Vukmirović and Ramiz Sadiku and the Monument to the Šar Mountains Partisan Detachment were chosen for the analysis. The aim of this paper is to determine the relations between the sculptural form and man, but also the basic urban-architectural and monumental relations, characteristics, messages, and meanings, through the interpretation of the principles of spatial perception of the monuments. For the purposes of this research, data on the available archival material and the existing condition of the monuments were collected, an interview was conducted with the author of the monuments, Svetomir Arsić Basara, and then an urban-architectural and symbolic interpretation of the monuments was given. The paper provides a historical overview, an overview of social circumstances and relations, as well as authorial processes in urban-architectural designing solutions, therefore, this paper can contribute to the expansion of the current modest knowledge about the urban-architectural characteristics of the monuments, and a better understanding of their memorial symbolism

No full textFunding Information: This research was supported by the National Research Foundation of Korea (contract grant number NRF-2015R1A3A2066301) and the author Kokkarachedu Varaprasad wishes to acknowledge the Programa de Atracción e Inserciun de Capital Humano Avanzado (PAI) Proyecto No. 781302011, CONICYT, Chile and the CIPA, CONICYT Regional PRFC0002. Publisher Copyright: © 2016 Wiley Periodicals, Inc.For the first time, green-tea (GT)-based magnetic nanohydrogels were developed for drug-delivery purposes. The hydrogel matrices were fabricated via the in situ polymerization of acrylamide with GT molecules. Magnetic nanoparticles were synthesized by the reduction of the 1:2 molar ratio mixture of ferrous sulfate heptahydrate and ferric chloride hexahydrate with an ammonia solution. A chemotherapeutic drug, 5-fluorouracil, was chosen as a model drug, and its releasing profiles in the presence and absence of the external magnetic field were evaluated at a pH of 7.4. We observed that in the presence of the applied magnetic field, these magnetic nanohydrogels released 2.86% more drug than in the absence of a magnetic field. The magnetic nanohydrogels were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, vibrating sample magnetometry, and transmission electron microscopy
