Authors: Soares Thiago , Tenório Winglison Henrique Do Nascimento
Published: March 2021

O artigo analisa seis videoclipes protagonizados por dois rappers brancos estadunidenses para traçar roteiros performáticos (TAYLOR, 2013) da masculinidade e da branquitude neste gênero musical. Ressalta a interseccionalidade como importante moduladora do enquadramento de produtos da indústria musical. A metodologia de análise midiática de videoclipes (SOARES, 2013) evidencia como o privilégio branco é teatralizado em videoclipes de rap em encenações que remontam a ideais de paternidade, maturidade e consumo.

Authors: Menéndez Sanchón José
Published: March 2021

El objetivo de la presente investigación in vitro fue comparar la adaptación marginal del Endosequence Root Repair Material (ERRM) y del Bio-C Repair cuando son utilizados en obturaciones retrógradas. Veinte dientes unirradiculares extraídos fueron estandarizados a 15 milímetros. Las raíces remanentes fueron instrumentadas y obturadas mediante la técnica de onda continua. Luego, fueron seccionados los 3 mm apicales de la raíz, y posteriormente se realizó la preparación retrógrada. A continuación, los 20 especímenes se dividieron aleatoriamente en dos grupos: Grupo A, en el cual las muestras se retrobturaron con ERRM en pasta; y Grupo B, en el que se usó Bio-C Repair. Por intermedio de un microscopio electrónico de barrido, se obtuvieron microfotografías a diferentes magnificaciones con el fin de medir, en ambos grupos, los espacios entre el material de retrobturación y las paredes de dentina. Los resultados indicaron que el ERRM en pasta presentó un espacio medio de 6.43 micras, mientras que para el Bio-C Repair, el espacio medio fue de 7.5 micras. Las pruebas estadísticas indicaron que no hubo diferencias significativas entre los dos grupos. En conclusión, el Endosequence Root Repair Material y el Bio-C Repair presentan una adaptación marginal similar cuando se utilizan en obturaciones retrógradas.

Authors: Kumbhakar Dharmakanta , Talukdar Partha Pratim
Published: March 2021

BACKGROUND The breast is composed of both specialised epithelial cells and stroma. Both benign and malignant lesions can occur in the breast as a palpable lump. Fine needle aspiration cytology (FNAC) is a rapid, easy to perform, minimally invasive and low cost first line high-diagnostic accuracy test for cytopathological evaluation of palpable breast lump with minimum complications. METHODS The study was carried out to evaluate the cytopathological patterns of 2706 palpable breast lumps by fine needle aspiration (FNA) procedure and cytohistopathological correlation of the available biopsied palpable breast lumps of the study in the Pathology department of Tezpur Medical College and Hospital, Assam, for a period of three years from July 01, 2016 to June 30, 2019. RESULTS Out of 2706 palpable breast lumps in the study, FNA smears of 19 (0.70 %) were inadequate for cytopathological reporting. Out of the remaining 2687 palpable breast lumps where FNA was adequate for cytopathological reporting, female patients (n = 2594) comprised 96.54 % and male patients (n = 93) comprised 3.46 % with a male and female ratio of 1:27.9. Out of the 2687 palpable breast lumps, 2318 were benign breast diseases (86.27 %) and 369 were malignant neoplasms (13.73 %), with a benign and malignant ratio of 6.28:1. Out of the benign breast lumps, fibroadenoma breast was seen in 1228 (52.98 %) and of the malignant neoplasms, infiltrating duct carcinoma was seen in 341 (92.41 %). Cytohistopathological correlation showed 98.70 % sensitivity, 99.38 % specificity, 99.35 % positive predictive value, 98.76 % negative predictive value, and 99.04 % diagnostic accuracy. CONCLUSIONS FNAC has high sensitivity and specificity in cytopathological diagnosis of palpable breast lumps. Based on the accurate cytopathological diagnosis of the palpable breast lumps, patients with palpable breast lumps can be given adequate treatment.

Published: March 2021

BACKGROUND To improve the quality of block (sensory and motor characteristics), postoperative pain management and reduce large doses of local anaesthetics, various adjuvants are used with local anaesthetic agents. We have evaluated dexmedetomidine as an adjuvant to 0.5 % ropivacaine in supraclavicular brachial plexus block in terms of onset and duration of sensory and motor block & duration of postoperative analgesia. METHODS This is a prospective randomised comparative study. 60 patients who were admitted for elective surgeries of the lower arm, at the level of elbow, forearm & hand were enrolled. They were divided in to two groups of 30 patients each as follows - group RD: supraclavicular brachial plexus block given with 30 mL of 0.5 % ropivacaine + 1 mL (100 μg) of dexmedetomidine. Group RC: supraclavicular brachial plexus block given with 30 mL of 0.5 % ropivacaine + 1 mL of normal saline. Various parameters like onset times and durations of sensory and motor block, duration of analgesia, total analgesic needed, and side-effects were recorded for each patient. RESULTS The time of onset of sensory and motor block was significantly early in dexmedetomidine group than in control group. The duration of sensory and motor block was significantly prolonged in group RD as compared to group RC. The duration of sensory block was 724.18 + 73.26 min in group RD (GD) and 582.16 + 93.12 min. in group RC (GC). The duration of analgesia was significantly prolonged in group RD. CONCLUSIONS Addition of dexmedetomidine as an adjuvant to ropivacaine is associated with early onset of sensory and motor block. The duration of sensory and motor block was prolonged. The duration of analgesia was prolonged and patients required less rescue analgesia. The use of dexmedetomidine was associated with reversible bradycardia and sedation score was less KEYWORDS Ropivacaine, Dexmedetomidine, Adjuvant, Supraclavicular Brachial Plexus Block

Authors: Ram Jagjeewan , Nigam Namrata , Singh Aparna , Khan Lubna
Published: March 2021

BACKGROUND The primary aspect of blood transfusion lies in the availability of blood and blood components which are tested and reported negative for transfusion transmitted infections (TTI’s). The increased seroprevalence of TTI’s indicate their prevalence in general public. The study was conducted to analyse the increasing seroprevalence of hepatitis C virus (HCV) over a period of 3 years. The objectives of the study determine the seroprevalence of hepatitis B (HBV), hepatitis C (HCV) and human immunodeficiency virus (HIV) among the voluntary blood donors at a tertiary care hospital & associated blood bank. METHODS This cross-sectional study was done at the Department of Transfusion Medicine, GSVM Medical College, Kanpur, Uttar Pradesh, over a period of 3 years from July 2017 to June 2020. The samples collected were screened by enzyme-linked immunosorbent assay (ELISA) tests. RESULTS A total of 69561 blood units were collected during this 3-year study from July 2017 to June 2020. Of all the blood bags screened, the highest prevalence was seen for HBV followed by HCV and HIV. 949 (1.4 %) were reactive for HBV, 75 (0.1 %) were reactive for HIV and 332 (0.5 %) were reactive for HCV. The results show a remarkable increase in the seropositivity for hepatitis C infection. CONCLUSIONS The seroprevalence of HCV has seen an increase in case load over the years as compared to HBV and HIV. This increase in case volume is indicative of impending liver diseases progressing to chronic stage over the years. Thus, it is imperative to create awareness in the general population to help reduce the risk factors responsible for HCV infection.

Published: March 2021

Introduction: Since the start of COVID-19 pandemic in December 2019, until mid-April 2020 the total number of cases worldwide exceeded two millions and the death toll exceeded 130000 cases.
Objective: The current study conducted to explore the clinical and epidemiological characteristics of COVID-19 patients, fatality of this disease and its mortality risk factors in major hospitals affiliated with Tehran University of Medical Sciences (TUMS).
Methods: The data were collected in four major teaching hospitals affiliated with TUMS for all the patients that were admitted between Feb 19th and Apr 15th 2020 and were diagnosed as COVID-19 using reverse transcription polymerase chain reaction (RT-PCR), clinical diagnosis and/or lung computed tomography (CT) scan. The case fatality rate of the disease was estimated by age, sex, symptoms, comorbidities, and type of diagnosis. Logistic regression model was used to examine the associations between different factors and in-hospital deaths.
Results: By Apr 15th 2020, a total of 4377 patients were admitted with COVID-19 diagnosis in four selected hospitals and 496 (11.3%) of these patients died in hospital. The case fatality rate of this disease was 28.8% in the ≥80-year age group, which was the highest compared to the other age groups. The case fatality rates were 12.5% and 9.8% among men and women, respectively. The results of multiple logistic regression on the outcome of death indicated that age, sex, cough, myalgia, reduced consciousness at arrival and past history of cancer were significantly associated with in-hospital death. Adjusting the effect of other variables, for each 10-year increase in age, the odds of death due to COVID-19 was 1.61 times greater (adjusted OR 1.61, 95% CI: 1.51 to 1.72, p<0.001).
Conclusions: Older age, the male gender, past history of comorbidities (particularly cancer) and reduced consciousness at arrival are among the factors that can significantly increase the odds of in-hospital death in COVID 19 patients. These factors might be helpful in detecting and managing patients with poorer prognosis.

Introduction: Quality and safety is an important challenge in healthcare systems all over the world particularly in developing parts.
Objective: This survey aimed to assess patient safety culture (PSC) in emergency departments (EDs) in Yemen and identify its associated factors.
Methods: A questionnaire containing the Hospital Survey on Patient Safety Culture (HSOPSC) was distributed to ED physicians, nurses, and clinical, and non-clinical staff at three public teaching general hospitals. The percentages of positive responses on the 12 patient safety dimensions and the summation of PSC and two outcomes (overall patient safety grade and adverse events reported in the past year) were assessed. Factors associated with PSC aggregate score were analyzed.
Results: finally, out of 400 questionnaires, 250 (64%) were analyzed. In total, 207 (82.3%) participants were nurses and physicians; 140 (56.0%) were male; 134 (53.6%) were less than 30 years old; and 134 (53.6%) had a university degree. Participants provided the highest ratings for the “teamwork within units” PSC composite (67%). The lowest rating was for “non-punitive response to error” (21.3%). A total of 120 (48.1%) participants did not report any events in the past year and 99 (39.7%) gave their hospital an “excellent/very good” overall patient safety grade. There were signiﬁcant differences between the hospitals’ EDs in the rating of “handoffs and transitions” (p=0.016), “teamwork within units” (p=0.018), and “frequency of adverse events reported” (p=0.016). Staff working in intensive care units (8.4%, n=21) had lower patient safety aggregate scores.
Conclusions: PSC ratings appear to be low in Yemen. This study emphasizes the need to create and maintain a PSC in EDs through the implementation of quality improvement strategies and environment of transparency, open communications, and continuous learning.

Authors: Asadi Kamran , Soleimanmanesh Yasaman , Keymoradzadeh Arman , Soleimanmanesh Nazanin
Published: March 2021

Background: Femoral neck fracture as a prevalent skeletal injury accounts for 7% of orthopedic hospital admission. The aim of the present study is to evaluate the functional outcome of patients with femoral neck fracture treated with total hip arthroplasty (THA) and compare them with those undergoing fixation treatment.
Methods: In this study, we reviewed patients in the age range of 45-60 years old with femoral neck fracture during 2007-2017. The subjects were assigned to either THA or fixation group. The primary outcome was hip function, evaluated with the Harris Hip Scale (HHS). Secondary outcomes included pain, local infection, avascular necrosis (AVN), thromboembolic event, loosening of the prosthetic and internal fixation device, prosthetic dislocation, non-union, and delayed-union.
Results: In this study, 34 patients with displaced fracture of femoral neck were treated with acute THA and 38 patients were treated with fixation. The HHS was higher in the THA group compared to the fixation group (P < 0.050). The results of the present study indicated no significant difference in early postoperative complications over the first month between the two groups, but frequency of complications such as non-union, AVN, pain and loosening of the internal fixation device in the fixation group were significantly higher than the THA group after six months (P < 0.050).
Conclusion: Over a period of six months, THA provided better hip function and significantly fewer postoperative complications compared to fixation.

Background and Objective: People that undergo assisted infertility treatments experience more sleep problems. Although Pittsburgh Sleep Quality Index (PSQI) frequently has been used as a sleep quality assessment scale in different clinical and non-clinical settings, different sample characteristics may account for different structures. The current study aimed to evaluate the factor structure of PSQI among women seeking infertility treatment in Iran.
Materials and Methods: Using a convenience sampling method, 157 infertile women or women whose husbands had infertility problems were included in a cross-sectional study in Royan Institute, a main referral infertility center in Tehran, Iran. The factor structure of PSQI was evaluated through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).
Results: The Cronbach’s alpha coefficient for PSQI was 0.65. A two-factor model was extracted by EFA; 56% of the total variance was accounted for by this model. The results of CFA indicated that extracted model obtained acceptable fit statistics [comparative fit index (CFI) = 0.942, standardized root mean square residual (SRMR) = 0.042, root mean square error of approximation (RMSEA) = 0.128, χ2 = 19.8, degree of freedom (df) = 12, P = 0.071] compared to other original single-factor or 3-factor models.
Conclusion: Our results revealed the limited usefulness of single-factor structure of PSQI. A two-factor model of Persian version of PSQI should be used to assess sleep problems among women seeking assisted infertility treatments.

Published: March 2021

Background and Objective: Alopecia is one of the most common skin disorders that can affect the quality of life (QOL) in patients. Since few studies have simultaneously evaluated the QOL and quality of sleep in patients with alopecia, this study aimed to evaluate these two important factors in patients with different types of hair loss and among demographic variables.
Materials and Methods: Using a convenience sampling method, this cross-sectional study was performed on all patients with various types of alopecia referring to the Dermatology Clinic of Rasoul-e-Akram Hospital, Tehran, Iran, in 2016. For data collection, Dermatology Life Quality Index (DLQI), Short Form Health Survey (SF-36), and Pittsburgh Sleep Quality Index (PSQI) questionnaires were used.
Results: A total of 70 patients with four types of hair loss, including androgenic alopecia, alopecia areata, telogen effluvium, and discoid lupus erythematosus (DLE) were evaluated. The overall sleep quality score was 5.51 ± 2.93, which was not significantly different in all four patient groups (P > 0.05). The overall DLQI score was 4.40 ± 4.30, which had little effect on the QOL in most patients with alopecia (40.6%). The overall QOL and quality of sleep scores were not significantly correlated with such demographic variables as age, gender, marital status, education, and employment (P > 0.05). The SF-36 questionnaire and DLQI had a significant inverse relationship (r = -0.285, P = 0.026).
Conclusion: Our study showed that the quality of sleep and QOL were affected in all four types of patients with alopecia. As a result, attention to quality of sleep and QOL in these patients with any demographic characteristics is important. However, more studies are needed to confirm the results.

Published: March 2021

Background and Objective: Studies indicate that people with multiple sclerosis (MS) are at increased risk of sleep disorders and the resulting negative outcomes. The aim of this study was to evaluate sleep quality in patients with MS.
Materials and Methods: In this case-control study, 110 patients with all confirmed types of MS as a case group and 110 healthy subjects as control group were evaluated in terms of sleep quality using Pittsburgh Sleep Quality Index (PSQI). The data collected was analyzed using t-test and chi-square tests.
Results: Total score of PSQI was significantly higher in patients with MS than that of the control group (7.32 ± 2.78 vs. 5.30 ± 2.00, P = 0.001). Furthermore, PSQI scores of patients with MS was significantly higher than that of the control group in subscales including sleep latency (1.14 ± 0.99 vs 0.85 ± 0.91, P = 0.029), sleep duration (1.09 ± 0.80 vs. 0.83 ± 0.88, P = 0.048), habitual sleep efficiency (1.15 ± 0.92 vs. 0.85 ± 0.83, P = 0.017), sleep disturbance (1.25 ± 0.96 vs 0.96 ± 0.88, P = 0.013), use of sleep medication (0.69 ± 0.94 vs. 0.33 ± 0.65, P = 0.001), and daytime dysfunction (0.88 ± 0.93 vs. 32.2 ± 0.69, P = 0.001).
Conclusion: Patients with MS had a significantly more improper sleep quality compared to the control group. So, poor sleep quality has a negative effect on daily activities and social communication of these patients and generally reduce their quality of life (QOL).
Assessing Sleep Quality and Its Effects on Academic Performance among University Students
Authors: Hossain Md Moyazzem , Rahman Md Habibur
Published: March 2021

Background and Objective: Insufficient sleep duration as well as quality is becoming endemic in our modern society. The time of going to bed and sleep quality and quantity are linked with students’ learning abilities and academic accomplishment. Therefore, this paper firstly opted to measure the level of sleep quality of the students of Jahangirnagar University, Savar, Dhaka-1342, Bangladesh, and finally detect the association between quality of sleep and academic achievement among the students.
Materials and Methods: The primary data were collected through a self-administered questionnaire from 334 students with a response rate about 84 percent during February to March 2019. Pittsburgh Sleep Quality Index (PSQI) was used to measure the sleep quality of the students. The percent distribution, descriptive statistics, and multiple regression were employed to identify the influence of the components of sleep quality on academic performance.
Results: Only the sleep quality of one-fourth of the students was good. Moreover, sleep duration, subjective sleep quality, and daytime dysfunction were positively related to the academic performance; however, sleep latency, sleep disturbances, use of sleeping medications, and habitual sleep efficiency were inversely associated with the academic performance of the students.
Conclusion: Academic performance of a student was related to the components of sleep quality. Thus, this study indicates that students with poor academic performance have problems regarding sleep issues. Medical advice should be followed to maintain a healthier lifestyle including adequate rest time.
Somnolence and Periodic Limb Movements due to Treatment with Baclofen
Authors: Najjar Muhammad
Published: March 2021

Background and Objective: Excessive sleepiness is a common reason for a referral to sleep medicine clinics. The clinical picture and context usually suggest the underlying cause; however, all possibilities should be considered and only after sleep studies are done, one can determine the likely cause of the patient’s symptoms.
Case Report: We presented the case of a man who was referred for evaluation of hypersomnolence along with snoring and possible apnea during sleep. Obstructive sleep apnea (OSA) was suspected, so home sleep apnea test (HSAT) and later polysomnography (PSG) were performed and both ruled out this possibility. The PSG showed frequent periodic limb movements (PLMs), some associated with arousal; abnormal sleep structure suggested the effect of medication. The patient had been taking baclofen for musculoskeletal pain and it was concluded that baclofen was the cause of the patient’s somnolence and PLMs. The patient’s clinical presentation was compounded by his history of post-traumatic stress disorder (PTSD) and gastroesophageal reflux which probably caused increased arousals and the subjective feeling of poor sleep quality.
Conclusion: Treatment with medications that have sedative effects should be considered in all patients presenting with excessive daytime sleepiness even if the initial clinical picture suggests another possible cause. Baclofen can cause PLMs, sedation, changes in N3 stage, and reduction in rapid eye movement (REM) sleep.

Os resultados demonstram que os alunos da ESAs têm conhecimento aprofundado sobre a matriz energética local, apesar de demonstrar conhecimento superficial sobre a importância das energias no seu cotidiano, pelo fato da maior parte delas não ser fonte do uso local e o tema não constar na grade curricular do ensino moçambicano. Concluindo-se que a aprendizagem através de situações concretas e de vivência dos alunos é importante na consolidação dos conhecimentos científicos e a diminuição da distancia entre o conhecimento científico e o senso comum.

Published: March 2021

Background: The application of molecular methods for evaluating the Epinephelus species evolutionary variations is considered the backbone for the conservation process for these biological resources. Methods: In this study, the utility of the Otx1B gene sequence variations was evaluated for the identification of some Red Sea Epinephelus species (E. areolatus, E. malabaricus, E. summana, E. radiatus and E. chlorostigma) compared with other ray-finned fishes. Some Otx1B gene fragments were isolated, purified, sequenced, analyzed (663 bp) and submitted to NCBI. Result: A total of 140 single nucleotide polymorphisms were identified among the evaluated fishes. The phylogenetic relations among the evaluated fishes were reconstructed using the Maximum Likelihood and Neighbor-Joining methods. The genus Epinephelus was distantly related to the group formed by genera Chlorurus, Scarus and Oxycheilinus. The DNA polymorphism and sequence conservation values were calculated. The estimated Otx1B gene fragment sequences have proven their ability to detect speciation in each studied fish genera.
An Incidental Finding of a Double-Lumen Trachea

Published: March 2021

The aim of this case report is to present an incidental finding of a firm tracheal septum in a 61-year-old woman. The patient was admitted to the hospital with mild dyspnea and a preliminary diagnosis of a tracheal subglottic stenosis. During microlaryngoscopy, just below the subglottic stenosis, a firm, vertical symphysis (septum), forming a double-lumen trachea was found. There was no record of any previous difficulties with intubation. A computed tomography scan performed after the microlaryngoscopy revealed an airway branch arising from the trachea at the level of thyroid gland and joining its lumen below. The radiological and endoscopic findings in the presented case hardly resemble the conditions described in the literature, as the discovered septum does not have a pseudomembranous nature, nor does it form a tracheal bronchus. Therefore, the finding is thought to be an unusual complication of multiple intubations in the past. This is an extremely rare finding and it is important to share our experience in managing a patient with the aforementioned post-intubation complications.

Introdução: A vigilância sindrómica permite a identificação precoce de alterações no padrão de morbilidade da população. Este estudo tem como objetivo avaliar a utilidade de indicadores relativos a cuidados de saúde primários e hospitalares, na vigilância da COVID-19.Material e Métodos: Foi realizada uma análise de séries temporais utilizando a taxa de incidência semanal de COVID-19 em Portugal Continental, entre as semanas 14/2020 (30 março a 05 abril) e 25/2020 (15 a 21 junho), e seis indicadores: 1) consultas em cuidados de saúde primários por COVID-19; 2) número de episódios de urgência por COVID-19; 3) número de episódios de urgência por pneumonia vírica; 4) número de internamentos por pneumonia vírica; 5) proporção de episódios de urgência por pneumonia vírica face ao total de episódios de urgência por pneumonia; e 6) proporção de internamentos por pneumonia vírica face ao total de internamentos por pneumonia. Foram calculadas correlações de Pearson e correlações cruzadas.Resultados: Foi encontrada uma correlação forte entre a taxa de incidência semanal de COVID-19 e todos os indicadores [(1) 0,76; (2) 0,82; (3) 0,77; (4) 0,84; (5) 0,86; e (6) 0,90]. Os episódios de urgência e internamento por pneumonias víricas detetam variações na frequência da doença, com uma semana de antecedência. As consultas em cuidados de saúde primários e urgências por COVID-19 registam uma semana de atraso relativamente à evolução da taxa de incidência. A proporção de pneumonias víricas face ao número de pneumonias em episódios de urgência, ou internamentos, encontra-se alinhada temporalmente com a evolução da taxa de incidência semanal de COVID-19.Discussão: O atraso encontrado no padrão de evolução de consultas em CSP, e de episódios de urgência por COVID-19 face à incidência de COVID-19, poderá estar relacionado com a reorganização dos serviços de saúde e criação de códigos específicos para estas consultas. Episódios de urgência e internamentos por pneumonia vírica poderão ser úteis para a deteção precoce de possíveis surtos de COVID-19. Pneumonias víricas poderão ter sido classificadas como pneumonias de causa indeterminada. A monitorização futura destes indicadores é necessária de modo a averiguar se a incidência de COVID-19 é influenciada significativamente por alterações na estratégia de testagem. Os indicadores deste trabalho serão uma mais valia para a adequação de estratégias de testagem, alocação de recursos de saúde a comunidades mais vulneráveis à morbilidade severa e avaliação de programas de vacinação. Como tal, os sistemas de vigilância com base em registos de saúde serão um complemento valioso ao SINAVE.Conclusão: Sugere-se que os indicadores em análise sejam utilizados de forma regular, com especial atenção à informação relativa a pneumonias víricas, como forma de detetar precocemente surtos de COVID-19. A informação relativa a pneumonias de causa indeterminada poderá ser considerada na monitorização da COVID-19.

KEBEBASAN KEHENDAK DALAM AL-QUR’AN: STUDI TAFSIR MU’TAZILAH
Authors: HK Muhammad Rizky
Published: March 2021

This article will describe the quranic interpretation of Mu’tazilite on theological verses which talked about free will. As a rationalist sect in Islamic tradition, Mu’tazilite offered different perspective, which has been known as a more logical sect than a mainstream thought in Islam. As a result, they came with a different perspective on a lot of theological aspects. Mu’tazilite believes, that human have a freedom to choose, Human has a free will. They are free to choose between good and evil. There’s no divine intervention in human act. In modern era, Existensialism came with same statement that human should be free. Existensialist believes that human existensce preceed their essence. This paper will describe the similarity of these two and would try to identificate mu’tazilite method of interpretation with existensialist point of view. This article use qualitative research method with descriptive analysis approach through the collection of related literature studies especially The thought of Jean Paul Sartre and Soren Kierkegaard, Two biggest existensialist. The results of this study indicate that the conception offree will has relevance with Islamic tradition itself, and have a relation wih western philosophy.
CITRA SANTRI PESANTREN DALAM CUPLIKAN FILM THE SANTRI
Authors: Hidayat Mansur
Published: March 2021

The appearance of the trailer for The Santri movie has sparked various responses on the internet, this can be observed from the existence of parties who are pro and contra with the movie trailer. This difference can be seen from the way the audience responds to and interpret the contents of the movie trailer. This study can understand the image of the student at Islamic Boarding School in the movie trailer of The Santri which can be seen through the account NU Channel on YouTube. The study used a descriptive qualitative approach model with content analysis on movie trailers. The results of the study show that the image of the student at an Islamic Boarding School in the movie trailer of The Santri can be divided into two parts, namely: first, an explicit image such as students must have self-confidence, have high dreams, love religion and their nation, have a good faith, and be a loyal friend. Second, implicit images such as students who have a simple, tough, and brave image, accept differences, and are open-minded.
Nations, Nationalism, National Identity: New Dimensions in Academic Discourse
Authors: Semenenko I.
Published: March 2021

Analyzing discourses on interethnic relations can contribute to a clearer understanding of the focal points of tensions in contemporary political communities sharing a common territory and common political institutions. These discourses represent the complex of problems related to nation-building and are generated both in the public sphere and in academic discussion. As such, they often develop separately one from the other. Assessing the current academic discourse on nations and nationalism, on nation-building and the nation-state, on citizenship, cultural diversity and interethnic conflict can contribute to the formation of the agenda of a politics of identity aimed at building a civic nation. Memory politics deserve special attention in this context, as the interpretation of historic memory has today become a powerful instrument that political elites can use to consolidate the nation and, in different contexts, to politicize ethnicity and deepen cleavages in existing nation-states. The affirmation of a positive civic (national) identity is a reference framework for modern democratic societies, and it is in meeting the challenges of politicizing ethnicity that political priorities and academic interests meet. However, the current domination of politics over academia in this conflict prone sphere contributes to its radicalization and to the formation of negative and exclusive identities that can be manipulated to pursue elitist group interests. Evaluating models of political organization alternative to the ones known today (such as “the nation-state”) does not aspire to “write off” the nation, but this can help to come up with visions and ideas politics can take up to overcome the conflict potential that contemporary societies generate over ethnic issues.

Published: March 2021

Background. Elafin and secretory leukocyte peptidase inhibitor may serve as the predictors of cervical shortening and preterm delivery in twin gestation.
Material and Methods. A prospective observational study was conducted between September 2016 and March 2017. Cervicovaginal swabs collected from 40 women with twin gestation were analysed and the mRNA expression of elafin and secretory leukocyte peptidase inhibitor (SLPI) correlated with preterm delivery.
Results. The mean gestational age at delivery was 35.6 ± 5.8 weeks, with 23 women delivering before 37 weeks (57.5%), 7 before 34 weeks (17.5%) and 3 before 32 weeks of gestation (7.5%). The mRNA expression of elafin and SLPI was not dependent on chorionicity and did not correlate with gestational age at delivery.
Conclusions. Elafin and SLPI are not appropriate predictors of preterm delivery in twins.
Temperature Dependent Viral Tropism (TDVT): Understanding Viral Seasonality and Pathogenicity as Applied to the Avoidance and Treatment of Endemic Viral Respiratory Illnesses
Authors: Shaw Stewart Patrick D. , Bach Julia
Published: March 2021

This review seeks to explain four features of viral respiratory illnesses that have perplexed generations of virologists: (1) the seasonal timing of respiratory illness; (2) the common viruses causing respiratory illness worldwide, including year-round disease in the Tropics; (3) the rapid response of outbreaks to weather, specifically temperature; (4) the rapid arrival and termination of epidemics caused by influenza and other viruses. The inadequacy of the popular explanations of seasonality is discussed, and a simple hypothesis is proposed, called Temperature Dependent Viral Tropism (TDVT), that is compatible with the above features of respiratory illness. TDVT notes that viruses can transmit themselves more effectively if they moderate their pathogenicity (thereby maintaining host mobility) and suggests that endemic respiratory viruses accomplish this by developing thermal sensitivity within a range that supports organ-specific viral tropism within the human body, whereby they replicate most rapidly at temperatures below body temperature. This allows them to confine themselves to the upper respiratory tract and to avoid infecting the lungs, heart, gut etc. Biochemical and tissue-culture studies show that “wild” respiratory viruses show such natural thermal sensitivity. The typical early autumn surge of colds and the existence of respiratory illness in the Tropics year-round at intermediate levels are explained by the tendency for strains to adapt their thermal sensitivity to their local climate and season. The TDVT hypothesis has important practical implications for preventing and treating respiratory illness including Covid-19. TVDT is testable with many options for experiments to increase our understanding of viral seasonality and pathogenicity.
Chronic Expanding Hematomas That Occurred 20 Years or More After Primary Total Hip Arthroplasty

Published: March 2021

Case:

We report 2 patients who developed chronic expanding hematomas (CEHs) more than 20 years after ceramic-on-polyethylene total hip arthroplasty (THA). One CEH occurred after a minor fall, and the other appeared with no obvious injury. Neither of the 2 was on anticoagulation. Each caused extensive osteolysis.

Conclusion:

The only 2 previously reported post-THA cases of CEH involved metal-on-metal THAs and occurred several years after the index THA. Our patients show that CEH also can occur after ceramic-on-polyethylene THA, even after an uneventful clinical course of more than 20 years. Complete removal of both hematoma stopped osteolytic progression, with no recurrence to date.
