Background: Postoperative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG) is one of the most common complications that can contribute to an increased risk of mortality, particularly in older patients. The identification of predictors of POAF after CABG could impact patient care. This study aims to determine the risk factors of POAF in patients ≥60 years old who underwent isolated on-pump coronary artery bypass grafting (ONCAB) in order to provide a basis for the prevention and treatment of POAF after ONCAB.
Methods: Between October 2011 and November 2015, a total of 304 patients ≥60 years old underwent isolated ONCAB in our department. The patients were divided into 2 groups, the AF group and the non-AF group, according to the occurrence of POAF. A retrospective analysis was performed on the general characteristics and perioperative data of the patients. Logistic regression analysis was used to identify the predictors of POAF after ONCAB in patients ≥60 years old.
Results: The incidence of POAF after ONCAB in patients ≥60 years old was 23.36% (71/304). Statistically significant differences were observed in patients’ age, history of hypertension, left atrium diameter, European System for Cardiac Operative Risk Evaluation (EuroSCORE) I and II, and the highest level of serum creatinine after operation (all P < .05). Logistic regression analyses showed that a history of hypertension (OR = 2.575, CI 1.208-5.488, P = .014), left atrium diameter (OR = 1.105, CI 1.047-1.167, P = .000) and EuroSCORE I score (OR = 1.132, CI 1.001-1.279, P = .048) were independent risk factors for POAF after ONCAB in patients ≥60 years old.
Conclusion: The occurrence of POAF after isolated ONCAB in patients ≥60 years old was affected by many risk factors; a history of hypertension, the left atrium diameter and the EuroSCORE I score were all predictors of POAF.

Published: March 2020

Introduction: Cancer cells rely on glycolysis to generate energy and synthesize biomass for cell growth and proliferation (the Warburg effect). Recent studies have shown that citrate has an inhibitory effect on several cancer cells, such as human gastric cancer and ovarian cancer, by inhibiting glycolysis. In this study, we investigated the effects of citrate on the proliferation and apoptosis induction of hepatocellular carcinoma cells.
Methods: HepG2 hepatocellular carcinoma cell line was used in this study. The cell proliferation was evaluated by Alamar blue assay. The apoptotic status of the HepG2 cells was recorded by Annexin V/7-AAD assay and caspase 3/7 activation assay. DNA fragmentation was evaluated by nucleus staining assay with Hoechst 33342.
Results: The results showed that citrate is able to inhibit the proliferation of HepG2 cells and induce apoptosis in these cells. The initiation time of apoptosis is 4 hours after treatment with 10 mM citrate. Morphology characteristics of DNA fragmentation and broken membranes were also recorded in the apoptotic cells.
Conclusion: In conclusion, our study demonstrates that citrate causes HepG2 cell death by the apoptosis pathway.

Published: March 2020

Background: Academic stress is an important research topic due to the effect it has on the
quality of life of students, future professionals and therefore, adult contributors in a society.
It has been shown that students in the health field face additional stressors specific from
their careers, and suffer greater stress than the general population of the same age.
Methods: 52 students, 23 from Physiotherapy and 29 from Medicine programs were
surveyed with Academic Stressors Academic Scale (SAS) to know academic stress level
and IL-6 was quantified in serum.
Results: It was found that students who perceive the academic semester as stressful
“fairly often” and “many times”, increases in 50%, 75% and 76.9% during the semester;
while “anxiety/distress” feeling was predominant. The most frequent SAS scale factors
were “methodological deficiencies”, “student overload”, “beliefs about performance”, “lack
of content value”, “participation” and “exams”
Conclusions: The study revealed an IL-6 increment, and their association with
“Methodological Deficiencies” at 1st moment. This study showed the importance of
academic stressors identification at same time that it is a call to construct strategies to
reduce stressors in University context
Estilo de vida de estudiantes de la Universidad del Atlántico: un estudio descriptivo-transversal
Authors: NIETO MENDOZA ISAAC 
Published: March 2020

Introducción: El estilo de vida se comprende como una serie de comportamientos de habitual práctica por parte de un individuo —que son conscientes y voluntarios—, y que inciden —negativa o positivamente— en su calidad de vida.
Métodos: Se aplicó un cuestionario para conocer el estilo de vida de los universitarios, denominado <<Fantástico>>, el cual valora aspectos relacionados a la familia y amigos, asociatividad y actividad física, nutrición, tabaco, alcohol y otras drogas, sueño y estrés, trabajo y tipo de personalidad, introspección control de salud y conducta sexual y otras conductas. Se tuvo en cuenta una metodología de diseño cuantitativo, tipo descriptivo y corte transversal, cuya unidad de análisis fue de 404 universitarios (57,9% de sexo masculino y 42,1% femenino), en el semestre 2018-2.
Resultados: se hizo notoria una tendencia de la muestra hacia los indicadores malo (46,8%) y existe riesgo (31,7%), lo cual da cuenta de que el estilo de vida de los universitarios —en gran medida— es poco saludable. Asimismo, se hace notoria una relación entre el estilo de vida poco saludable y el sexo masculino, ya que este se ubica mayormente en las totalidades que indican malo (27,8%) y alto riesgo (24,7%).
Conclusión: Es importante —desde la cátedra Deporte Formativo— inducir a los universitarios hacia estilos de vida saludable a través de la promoción de la actividad física, la sana alimentación, pautas para el control del estrés y que conozcan las enfermedades crónicas no transmisibles a fin de que se concienticen sobre la importancia de tener hábitos saludables que garanticen su bienestar y salud.

A Few Sketches on Environments Imprinted on the Novels of Ajneya
Authors: Das Beauti 
Published: March 2020

It is a well-known fact that the very environment which surrounds us bears a great impact on our body, mind and soul. Anybody can understand what will be the feelings of a person when he is surrounded by cold and heavy air in a situation that he comes in contact. In the same way the feelings of a person in a desert are well understood by anyone without having any question to the person concerned. This is why the environment portrayed by a novelist for the plotline of a novel is so important that it must suit to the characters in question, it must help the smooth progress of the plotline as well as it must pierce in to the heart of a reader, so that the reader can visualize the very movement of the protagonist at every moment of time. To air out our thoughts in this regard it might be the best way to cite the example of the environment that had been created by the great novelist Ernest Hemingway in his novel The Old Man and The Sea. He had allowed the old man to go to the sea again and again for a long period but he never allowed the old man to have success at his hand. In fact he had portrayed an environment of pessimism for the readers by not allowing the old man to have a success at his hand despite of his all efforts. In order to add more pessimism in the mind of a common reader he had given a nick name to the old man by Shalao. The very environment created by the author made every reader believe that the old man will never be successful at any cost, whatever the intensity of his effort may be. This is how one can imagine the influence of the environment on the mindset and belief of a common reader.
Analysing the Methods of Agrarian-Economic Terminology Lexicon Enrichment in French
Authors: Dvorakova Milena 
Published: March 2020

The paper deals with one of the principles of term formation in the economic terminology of the French language. When analyzing ways of enriching the French agrarian-economic terminology, a word-formation process of terminologization is discussed in more detail. To determine the degree of agrarian-economic terminologization in the French text, a statistical survey was carried out, based on four types of document - a scientific publication, university textbooks, popular professional publication and scientific paper. It would be necessary to use the results of the statistical analysis in the teaching of i.e., languages because the knowledge of the principle of the term formation is one of the prerequisites for mastering the terminology.

Published: March 2020

This study aims to explore the subjugated woman in male dominant society in ZoraNaele Hurston’s novel “Their Eyes Were Watching God”. “Their Eyes Were Watching God” has become the most widely read and highly acclaimed novel in the canon of African-American Literature. One of the most important and enduring books of the twentieth century, “Their Eyes Were Watching God” brings to life a Southern love story with the wit and pathos found only in the writing of ZoraNeale Hurston. The novel follows the fortunes of Janie Crawford, a woman living in the black town of Eaton, Florida. This study spotlights how women live under social restrained destiny; where they suffer letdown, thwarting, dismay and mocking. Subjugation against women which transcends all natural, ethnic and class boundaries. Women are mistreated by patriarchy financially, politically, socially and mentally. Where there is patriarchy, the woman is the other. She's objectified and marginalized, characterized just by her distinction from “ale standard”. All women’s activist movement specifically advances social change and women’ equality. A woman is not considered an equal, but rather the other, and thus inferior to a man. All these problems and incidents are dangerous for women’s identity. The research deals with major aspects of hegemonic masculinity, and violence against women. This research will study the threats to female identity in the light of Lois Tyson’s feministic views.
A Translation into English of Khalil I. Al-Fuzai’s1 “Reaching the End”2
Authors: Dohal Gassim H. 
Published: March 2020

A youth cannot marry his cousin because her father refuses for economic reasons. This story shows how the Saudi Arabian society connects marriage with wealth, even when it comes to relatives who are obligated culturally to take care of one another. A father is ready to sacrifice his daughter for a rich person, hoping that marriage bargain will improve his economic status. The customs of the society validate that a father can do to his daughter what he sees as good. Also, the norms of the society require a younger relative to obey an older one, even working for him; a person cannot fight back or challenge an elder. Accordingly, the relation between relatives is a relation of traditional and cultural power recognized and imposed by the society.
In this story, the protagonist is colonized physically and mentally: in addition to having been exploited for fifteen years, he believes that his life is secured with his uncle. And hence, “he almost lost his personal independence,” as the story states. He can lose anything as long as his future is granted, for he believes that he is the only heir of his uncle. But after his uncle’s refusal of his proposal, he becomes aware of being marginalized and colonized. He has to struggle and search for his identity after being considered as “a nobody in the world of the living.” Like the protagonist who kills his father in the previous story, the youth of this story “deludes himself that he is brave and that he has to prove it.”
Yet as an oppressed and marginalized person, the main character is neither supposed nor expected to practice oppression. But he thinks of violating his uncle’s daughter’s honor—for no fault except that she is his uncle’s daughter. In a culture that valorizes masculine values, the wretched girl becomes the victim of both her father, who wants to sell her as a commodity for the one who pays more, and of her cousin, who wants to exploit her in order to achieve his goals. Finally, in my translation, some well-known words are kept with their original pronunciation and written in italics to keep the reader aware of the Arabic text.3

Background: India has the maximum burden of both non MDR tuberculosis (TB) and Multidrug-Resistant (MDR) TB, as per data reported in Global TB Report 2018 and tuberculosis is remains one of the most common cause of pleural effusions.Methods: This was a cross-sectional study conducted in Department of Respiratory Diseases and a total of 110 patients with pleural effusion were included in the study, which were enrolled for treatment from July 2018 to June 2019.Results: One hundred and ten patients with pleural effusion were enrolled during the study period. There were 65 males (59%) and 45 (40.9%) females. The overall mean age for males and females were 44.4±18.84 years (35-87 years) and 38.28±17.66 years (35-87 years) respectively. Tuberculous Pleural Effusion group (TPE) seen in 82 patients. Right sided pleural effusion (69.5 %) were more common than left sided (30.4 %). In TPE group the mean pleural fluid ADA level were 86.41±38.08 IU/L (range: 14-195 IU/L). The Malignant Pleural Effusion (MPE) group included 21 patients. In MPE group the mean pleural fluid ADA level were 34.10±32.88 IU/L (range: 8-144 IU/L). The difference in pleural fluid ADA levels between TPE and MPE group was statistically highly significant.Conclusions: Tuberculous pleural effusion was the most common cause of pleural effusion in present study and observed in 74.5% cases.

Authors: Fatima Saman , Khan Ruhi 
Published: March 2020

Background: Stroke is the second most common cause of mortality worldwide and a major contributor to morbidity and chronic adult disability. To study the prognostic significance of serum cortisol and serum albumin in patients of ischemic stroke was the objective.Methods: This hospital based observational cohort prospective study was undertaken in the Department of Medicine in collaboration with the Departments of Radio diagnosis and Pathology, Jawahar Lal Nehru Medical College and Hospital, AMU, Aligarh from January 2017 to November 2018. By convenience method for sampling, 102 patients who were admitted with the diagnosis of acute ischemic stroke to IPD of JNMCH, Aligarh, on clinical as well as radiological grounds were taken into study.Results: Mean cortisol was 450.84±190.35 nmol/L. The (mean±SD) of serum cortisol was 258.10±77.91 ng/ml in patients with good outcome and 585.77±113.34ng/ml in patients with poor outcome. (p<0.05, r= 0.812). Mean serum albumin was 2.83±0.76 gm/dl. The (mean±SD) of serum albumin was 3.47±0.64mg/dl in patients with good outcome and it was comparatively lower in patients with poor outcome (2.38±0.45mg/dl). (p <0.01, r=-0.659).Conclusions: Serum albumin, serum cortisol are prognostic indicators of functional outcome at 3 months in patients of ischemic stroke.
High sensitivity C-reactive protein level in cerebrovascular accident
Authors: Rajesh Kumar Sonal , Vidya T. A. 
Published: March 2020

Background: Stroke is the second leading cause of death worldwide according to WHO. High sensitivity C-Reactive Protein (hs-CRP) is an acute phase reactant which is being studied extensively to delineate its role in development of stroke as well as in prognostication. This study was done to assess correlation of hs-CRP with risk factors of stroke and its association with types of stroke and prognosis.Methods: A prospective case control study of 100 patients with acute stroke along with 100 controls was conducted with informed consent. At baseline, hs-CRP levels were measured and Modified Rankin Scale (MRS) was assessed. On day 90 the Modified Rankin Scale was assessed again. Patients were divided into groups based on hs-CRP levels and MRS and the results were analysed.Results: Prevalence of stroke was more in men than women (p=0.0002). Statistically significant difference was found between mean hs-CRP levels in men (4.722±0.8982 mg/L) and women (4.133±0.9446 mg/L) (p=0.005) and between cases and controls (p=0.0003). There was no significant association with type of stroke (p=0.456). Mean total cholesterol levels between cases and controls showed statistically significant difference (p=0.0005). High MRS was significantly associated with high hs-CRP levels (p=0.003). Higher hs-CRP on day 1 correlated with higher MRS on day 90.Conclusions: hs-CRP level is increased in stroke and shows significant association with severity of stroke and prognosis.
An observational study of the evaluation of fatty liver in non-alcoholics with metabolic syndrome using fatty liver index and its correlation with USG elastography
Authors: Danasekaran Vaishnavi , Narayanan M. 
Published: March 2020

Background: NAFLD (Non Alcoholic Fatty Liver Disease) is being considered the hepatic component of metabolic syndrome. It is now the most common cause of chronic liver disease worldwide and needs to be addressed urgently as it is asymptomatic and widely prevalent and can progress to cirrhosis and hepatocellular carcinoma. There is a need for simpler methods to diagnose the condition in modern day practice which will help in identifying vulnerable subjects and in bringing about awareness and lifestyle modifications focused on reversal of the condition. Aim of this study was to check the applicability of the fatty liver index in modern day out patient practice using formula based FLI calculator.Methods: It was a cross sectional study on patients with metabolic syndrome in a tertiary care hospital. 60 patients with metabolic syndrome, both male and female above the age of 30 years and who were non-alcoholics were enrolled in the study. BMI, waist circumference, lipid profile and GGT were obtained and FLI calculated. It was compared with the ultrasound and Elastography reports. Chi square test, Independent t test and ANOVA test were used for comparing parameters. A p value of <0.05 was considered statistically significant.Results: Among 60 patients all had fatty liver which emphasizes that fatty liver is the hepatic component of metabolic syndrome. There is a significant correlation between BMI (Body Mass Index) and waist circumference in predicting fatty liver and to some extent its grade. Patients with higher BMI had a greater grade of fatty liver.Conclusions: The fatty liver index is a reliable predictor of fatty liver in people with metabolic syndrome. The grade of fatty liver increases with increase in waist circumference and increased BMI. Ultrasound and Elastography are reliable non invasive methods of detecting fatty liver. BMI and Waist circumference are strong predictive factors for fatty liver.
A cross sectional study of lipid profile in stroke patients
Authors: C. Nirmala A. , S. Hrishikesh 
Published: March 2020

Background: Atherosclerosis affects multiple vascular beds, accounting for nearly all of coronary heart disease and some proportion of ischemic strokes. Serum lipid levels have an effect on the short-term mortality due to strokes. But in some studies, there was no dyslipidemia in patients who presented with acute stroke. It is important to evaluate the serum lipid levels in both the types of strokes to guide lipid lowering therapy which can reduce incidence of stroke and related mortality. This study is undertaken to evaluate the role of serum lipids in patients of stroke in our centre.Methods: It is a cross sectional study, conducted on 176 patients of stroke, who were assessed by NIHSS stroke scale clinically. Serum lipid profile was measured in all patients. Data was entered in Microsoft Excel and analysed by descriptive statistics. Chi Square test was used for association of qualitative variables. A p value<0.05 was considered statistically significant.Results: In this study conducted on 176 patients, LDL values were deranged more in CVA-bleed group compared to CVA-infarct group. BMI was the best anthropometric measure that correlated with LDL. LDL was also the most common parameter that was deranged in nonsmokers (61.8%) whereas in smokers, total cholesterol (66.3%) was most commonly deranged. Triglyceride and VLDL values were deranged more commonly in diabetic group than in non-diabetic group. A total of 123 out of 145patinets with CVA- infarct, had deranged lipid profile and among patients with CVA- bleed 24 out of 32 had deranged lipid profile.Conclusions: Results of this study shows significant derangement in lipid profile especially in LDL cholesterol levels in both infarct and bleed group, therefore starting statin therapy would prove to be beneficial in preventing recurrence of stroke.
