Published: October 2020

Introduction: Globally, the numbers of elderly population are increasing which is one of the challenges for nurses in health care setting. Nurses' attitude towards elderly people is associated to quality of care they provide. 

Objective To identify attitude of nurses towards care of elderly people in teaching hospitals of Kathmandu valley. 

Methodology A cross sectional research design was used to identify attitude of nurses towards care of elderly people. Proportionate stratified random sampling technique was used to select 450 nurses. Ethical approval was taken from Institutional Review Board of Nepal Health Research Council. Data collection was done from 17 April 2017 to 16 April 2018 by using self-administrative questionnaire on socio-demographic characteristics and Multi-factorial Attitude Questionnaires (MAQ) to measure attitude. Data analysis was done using descriptive and inferential statistics. 

Results The study revealed that 55.3% of respondents had negative attitude and 44.7% had positive attitude towards care of elderly people. There was significant association between age, marital status, studied geriatric nursing and work experiences in nursing with attitudes of nurses. However, there is no association found of ethnicity, religion, type of family, living with elderly, education and currently working with elderly with attitudes of nurses. 

Conclusion From these findings, it is concluded that about more than half of the nurses had negative attitude towards care of elderly. Gerontological nursing course plays significant role in the attitude of nurses. Therefore, it should be given continuity in all level of nursing education for providing quality care of elderly people.
Septoplasty in Pediatric Population: A Ten Years' Experience
Authors: Koirala Krishna Prasad
Published: October 2020

Introduction: Septoplasty is a commonly performed surgical procedure worldwide in otorhinolaryngology. Septoplasty aims to correct the deviated nasal septum at the midline thereby opening the nasal airway in patients with long standing nasal obstruction secondary to septal deviation. Nasal breathing is important for proper facial growth and improvement of quality of life in children. Most surgeons are still reluctant to perform septoplasty in children. But septoplasty should be performed in children if there are severe breathing problems related to septal deviation.

Objectives: The objectives of this study were to identify the incidence of children presenting with symptomatic nasal septal deviation and to analyze the early outcomes of septal surgery in children with regard to improvement in nasal symptoms, residual disease and need for revision surgery.

Methodology: Children less than seventeen years of age who underwent septoplasty for symptomatic DNS from 1st January 2009 to 31st December 2018 were enrolled in the study. Patients having the follow up record of at least 6 months after surgery were included in the final analysis.

Results: There were 37 male and 13 female children enrolled in the study. Male to female ratio was 2.84:1.Majority of children in the study were of 13 years (24%). Left sided DNS was seen in 28 children and right sided DNS in 22 children. Bleeding requiring re-packing, septal hematoma, recurrent DNS, synechia and septal perforation were the common complications, which were comparable to adult population.

Conclusion: Early correction of the obstructed nose due to deviated nasal septum is essential to provide normal nasal breathing, relieve complications of mouth breathing and to promote normal craniofacial growth. Septoplasty can be performed in pediatric population with relatively good results without occurrence of nasal deformity and equal complications as that in adults.

Introduction: Stroke is life threatening & debilitating neurological disease, defined as focal neurological deficit of sudden onset lasting >24 hours & vascular in origin. Significant association between ischemic type of stroke with carotid artery disease seen, more prevalent with carotid artery stenosis. 

Objectives: This study was done to show association between extracranial carotid artery disease & cerebrovascular accidents (CVAs) with the help of Color Doppler Sonography (CDS). The association between carotid artery disease with associated risk factors were also assessed. 

Methodology: In this ethically approved prospective study, carotid CDS was done in 79 consecutive patients with diagnosis of acute ischemic stroke (AIS). The various parameters studied included peak systolic velocity (PSV) of internal carotid artery (ICA) & common carotid artery (CCA), ICA/CCA PSV ratio & plaque characteristics. The data collected was analyzed with appropriate statistical test of significance was calculated. 

Results: Total 79 patients with AIS included out of which 53 were males & 26 were females. The most common presenting complains were hemiparesis (30.4%) & most commonly associated risk factors included hypertension (62.02%). Right sided strokes were most common (44.3%) & middle cerebral artery was most commonly involved vascular territory. Significant stenosis (≥50%) of carotid artery was seen in 27 patients with ICA most common site (45.8%) for plaque formation. Bilateral carotid artery involvement (52.1%) with hypoechoic echotexture of atheromatous plaques (46.6%) was most responsible for significant stenosis & increased intima media thickness. Increased value of PSV & EDV was seen in the stenotic area in the proportion of stenosis with increased PSV ICA/CCA ratio of more than three indicates >60% stenosis. 

Conclusion: The present study showed well documented role of carotid doppler in detection of site & extent of carotid artery stenosis due to atheromatous plaques of various characteristics playing critical role in thromboembolic phenomenon responsible for development of stroke.

Authors: Kafle Santosh Upadhyaya , Singh Mrinalini , Kafle Neeta , Sinha Amrita
Published: October 2020

Introduction: The histopathological examination of appendectomy specimens is the gold standard method for diagnosis. The presence of eosinophil besides other inflammatory cells like neutrophils and mature lymphocytes within different histological layers of appendectomy specimens are common findings for labeling it under various groups. This finding supports the assumption that appendicitis is triggered by Type 1 hypersensitivity reaction. 

Objective: To evaluate the eosinophil count variation in appendectomy specimens in patients with the clinical diagnosis of appendicitis. 

Methodology: This is a cross sectional hospital based study of 144 appendectomy specimens obtained in Department of Pathology, Birat Medical College Teaching Hospital from January 2019 to December 2019. Socio-demographic data, association of histopathological patterns with age groups, gender and eosinophil count in various histopathological groups was compared and cross-tabulated using SPSS version 16. 

Result: Among 144 appendectomy specimens, male gender (50.70%) of 15-24 years age group (36.80%) was predominant. The commonest histopathological diagnosis was acute appendicitis (31.25%) with highest eosinophil count in all of its histological layers. The association of various histopathological patterns with age groups and gender were not statistically significant, whereas it revealed statistically significant correlation between eosinophil counts in all histological layers.

 Conclusion: Findings suggest that the eosinophil count variation in the entire histological layers correlate well among different histopathological patterns of appendectomy specimens. This reflects the high diagnostic value of evaluating the eosinophil count in appendectomy specimens.

Authors: Khadka Simanta , Joshi Purushottam , Subedi Basnet Prava , Pradhan Chandni
Published: October 2020

Introduction: Dacryocystorhinostomy (DCR) is the commonest surgery for nasolacrimal duct obstruction. Inhibition of the scarring process within the anastomosis and rhinostomy site which has been attributed to the failure of this procedure, might improve the success rate of DCR. The objective of this study was to evaluate the outcomes of DCR with Mitomycin-C (MMC) and to compare the results of DCR with and without MMC.

Materials and methods: A hospital based, prospective study was conducted in patients with primary acquired nasolacrimal duct obstruction. Standard conventional DCR was performed upto the level of creation of flaps. Application of MMC 0.2 mg/ml in and around the ostium and underneath the created flaps for two minutes was effected with cotton pledgets. The area was thoroughly washed with normal saline after removal of the pledgets. Rest of the surgery was completed as usual. The patients were followed up on the first postoperative day, one month and three months post surgery.

Results: A total of 60 cases, 30 in each group were allocated. The success rate of DCR with MMC was found to be 96.7% compared to 86.7% (p=0.35) in the DCR group at the end of three months duration.

Conclusions: Intraoperative application of MMC during conventional DCR surgery provides a comparatively higher success rate than DCR without MMC without posing any extra financial burden and adverse drug reaction to the patient.

Authors: Sood Gitanjli , Saraswat Neeraj Kumar , Samanta Ramanuj , Kumawat Devesh , Agrawal Ajai , Mittal Sanjeev Kumar
Published: October 2020

Introduction: Idiopathic thrombocytopenic purpura is an autoimmune hematological disorder characterized by isolated low platelet count without any known clinically apparent etiology. Although usually most cases are asymptomatic, it may present with bleeding manifestations in forms of bruises, petechiae, nose bleeding etc. Very rarely, it may present with ocular manifestations in the form of subretinal, preretinal, intraretinal or vitreous haemorrhage.

Case: A 26-year-old female presented to the ophthalmology department with chief complaint of sudden painless diminution of vision in both eyes for the last one week. Her best corrected visual acuity for distance was 20/200 in right eye and 20/600 in left eye. Dilated fundus examination showed right eye sub-internal limiting membrane (ILM) haemorrhage, left eye large subretinal and intra-retinal haemorrhages over posterior pole, with Roth’s spot in both eyes. Haematological investigations revealed moderate anaemia (Hemoglobin level of 7 gm %) and severe thrombocytopenia (25,000/ ul). Diagnosis of idiopathic thrombocytopenic purpura (ITP) was made after consultation with an internist. She was treated with systemic steroid and blood transfusion for systemic disease and kept under regular ophthalmic follow up. Over a period of six months, she showed gradual near total resolution of retinal hemorrhages in both eyes and improvement in visual acuity in both eyes.

Conclusion: This case gives a unique outlook to simultaneous varied ocular manifestations of ITP in a single patient and stresses upon thorough systemic evaluation in the presence of such manifestations. Optimization of systemic parameters without active ocular intervention in select cases may achieve favourable outcome.

Published: October 2020

Introduction: Anaemias are the commonest haematological disorders which cause ocular manifestations. With the progression of disease, retinal haemorrhages, dilated and tortuous veins, cotton wool spots may occur in the ocular fundus.

Case: An 18-year-old female patient presented to our out patient department with the sudden, painless, non-progressive blurring of vision in both eyes (best-corrected visual acuity in the right eye is 6/60, and left eye is 6/36) for two days. On Ophthalmological examination, bilateral pale tarsal conjunctiva, yellowish discolouration of the sclera, hyperemic optic discs, macular haemorrhages, superficial and deep haemorrhages with Roth spots were observed. The haematological evaluation showed the presence of Megaloblastic anaemia (with haemoglobin - 2.5g%). There was severe pallor on general examination. Mild hepatomegaly and splenomegaly were noted on the systemic examination and confirmed by ultrasound abdomen. Intraocular pressure was 11 mmHg in both eyes.

Conclusion: This case documents the occurrence of bilateral macular haemorrhages and Roth spots in megaloblastic anaemia without thrombocytopenia. Other causes of Roth spots were excluded. Treatment of anaemia showed resolution of Roth spots.

Double-entry analysis system (DEAS) for comprehensive quality evaluation of websites: case study in the tourism sector
Authors: Sanabre Carles , Pedraza-Jiménez Rafael , Vinyals-Mirabent Sara
Published: October 2020

A new analysis system for evaluating website quality is presented. It is characterized by its ability to interrelate and evaluate both technical and strategic aspects of a website. It is based on the premise that, while the technical aspects that govern the operation and functionality have a great impact on the quality of a website, they do not guarantee its success on their own. This approach differs from those commonly adopted in analysis systems, since until now most of them have been developed by adopting a predominantly operational or functional view.

Published: October 2020

Neste artigo, a partir de uma investigação centrada no uso, analisa-se a representação cognitiva de construções de predicação nominal do português brasileiro (PB) instanciadas pelo padrão básico [(S) V(funcional) X], em que se inserem os verbos ser, estar e ficar, protagonistas nos esquemas atributivos, equativos e apresentacionais. Para tanto, contemplam-se quantitativa e qualitativamente instâncias desses padrões em 58 produções escritas em PBL2 de 18 estudantes surdos do ensino superior e de 4 estudantes surdos do primeiro segmento do ensino fundamental, coletadas do Corpus do Núcleo de Estudos em Interlíngua e Surdez da UFRJ. Partimos dos pressupostos teóricos da Gramática de Construções Baseada no Uso (GOLDBERG, 2006; BYBEE, 2016; PEREK, 2015), a fim de sustentar a hipótese de que os esquemas analisados nos textos estão cognitivamente menos salientes para os participantes da pesquisa. Para a discussão, consideramos contextos de ensino pouco centrados na promoção de experiências de uso ricas e significativas capazes de conduzirem o acionamento eficiente de processos cognitivos de domínio geral para a estocagem de construções da L2 na memória do aprendiz. Os resultados demonstram que a instabilidade representacional em ambos os grupos de aprendizes é um indício da premente necessidade de diálogos entre o aporte teórico construcional e metodologias de ensino de L2.

This is the last article in the series of six articles, which altogether deal with the reconstruction of the history of the Ancient Israel. Its task is to offer the most plausible model of the emergence and the subsequent development as monarchic states of the kingdoms of Judaea and Israel. Methodologically, the research is based upon the narrative analysis. The key question is whether did exist the unified monarchy with Jerusalem as its capital during the rule of King David. To answer the question whether it did exist indeed and if yes then in what form one must compare the Biblical narratives with their author's ideology. The research shows that the actual “unified monarchy” was It appears that the unified monarchy was more likely “a project”, which in the actual narration was turned into the narrated past.
Martyrdom of John of Phanijoit MS Vat - Copt. 69, fols 40r-55v
Authors: Frangulian L. R.
Published: October 2020

This is the first translation into Russian of the “Martyrdom of John of Phanijoit”. The text is written in Coptic and originates from the beginning of the 13thcent. AD. The translation is preceded by an introduction, which comprises the history of the research as well as lists all the modern editions and translations of the “Martyrdom”. It is pointed out that there are some doubts about the original language of the text: some scholars argue that it could have been Arabic. There are also different speculations regarding the motives, which prompted the author to use Coptic, although at that time the Egyptian Christians almost completely switched to Arabic in everyday life. The composition of the “Martyrdom” follows the hagiographic canon, however, some expected topoi are missing. Among those are the torture of the Saint, the intervention of Heavenly Forces to strengthen the martyr. The main character in the “Martyrdom” is John, the flax seller. Having married a Muslim woman, he converted from Christianity to Islam. The narrative deals with what happened to John, when he decided to return to Christianity openly. The author of “Martyrdom” was a contemporary of the martyr and likely witnessed the events he described. Some of the characters mentioned in the “Martyrdom” are not fictitious but did exist indeed. All this makes the text a valuable source for the history of the Eastern Christianity in the Middle Ages.
The ghazal of Mir Taqi Mir: the formation of the poetic and literary language of Urdu
Authors: Vasilyeva L. A.
Published: October 2020

Mir Taqi Mir is a classic Urdu poet of the 18th century, an outstanding master of ghazal genre. With his work, Mir Taqi Mir proved that his native Urdu language possessed a vocabulary fit to express the finest nuances of poetic speech. He also made evident that the ghazals written in Urdu were not entirely imitations of those written in Persian, which formed the poetical basis of Urdu poetry. The article argues that the Mir Taqi Mir's heritage can be considered as a milestone in the evolutionary development of both poetical and literary language of Urdu. Throughout his life, the poet remained in a creative search. Working on a certain poetical theme, he often made recourse to it trying to bring out maximum possibilities for its realization by means of his native language. Analysis of numerous examples in the article can be considered as an effort to ascertain how borrowed poetical traditions were domesticated and how this process facilitated the selection of vocabulary and standardization of common literary language of Urdu.
Dialectics in early Yogācāra and bodhisattva ideal
Authors: Burmistrov S. L.
Published: October 2020

The article covers several aspects of Buddhist dialectics, as recorded in the last section of the “Abhidharma Compendium” (Abhidharma-samuccaya). It was compiled by Asanga (4th cent. AD) who was one of the founders of the Mahayana Buddhist school of Yogacara. Based on the Sanskrit text, the author gives a detailed account of Asanga's perception of the phenomenon of dialectics. He highlights the aspects as follows: the doctrine of reasoning methods, which provide the student with true knowledge, and the evidence of the reliability of this knowledge. The first part of dialectics comprises the essence of Buddhist teachings, which according to Asanga sees in the idea of three natures - the imagined, the dependent and the absolute (parikalpita, paratantra, pariniṣpanna) one. The second part covers the principles of rhetorics and the argumentation theory. Common principles lying in the basis of Buddhist rhetoric are determined by the bodhisattva ideal, or the ideal of an enlightened person who rises above the difference between samsara and nirvana, thus achieving the force to save other sentient beings from the ocean of saṃsāra. The author also points to the paradox that is immanent in Buddhist rhetoric: a preacher must show the emptiness of any conceptual construction by using the same constructions to enable the audience to get through them and to reach the non-conceptual reality. The article is an original study on the history of ancient and medieval Indian philosophy and rhetoric and will be of interest to everyone who deals with this problem.

Traditional coconut oil has the potential to be developed into commercial oil. These community service activities are a) coconut oil production practices, b) introduction of coconut oil refining technology and c) assessment of people's perceptions of coconut oil production. The variables used are the process of making oil, product quality, technology transfer and people's motivation to make oil. Questionnaire data were analyzed with contingencies to show the close relationship between variables and community groups. The results of the activity showed that there were two ways of making traditional coconut oil, using fresh coconut milk and fermented coconut milk. The resulting oil is crude coconut oil with a characteristic rancid odor, dark color and not durable. The process of oil production is a variable that shows real differences between young and old groups, while other variables are not significantly different. As many as 75% of young group respondents stated that the process of making coconut oil at a somewhat difficult to difficult level. The close relationship between the respondent group and the process of making coconut oil has high accuracy, which is 0.64. Improving coconut oil manufacturing techniques with the refining process can be one way to improve quality and efforts to support the commercialization of traditional coconut oil.

Published: October 2020

Die vorliegende Studie vergleicht Grundschulkinder aus Deutschland und Costa Rica bezüglich der Wahrnehmung ihrer heimischen Fauna. Hierbei wurden 56 Grundschulkinder aus Deutschland (Baden-Württemberg) mit 91 Grundschulkindern aus Costa Rica der dritten und vierten Klassenstufe miteinander verglichen. Die Kinder wurden gebeten, den jeweils heimischen Wald mit typischen Tieren nach ihren Vorstellungen zu zeichnen. Dabei konnte festgestellt werden, dass die deutschen Kinder signifikant mehr Wirbeltiere und mehr verschiedene Arten zeichneten als die Kinder aus Costa Rica. Beide Gruppen zeichneten mehr Wirbeltiere als Wirbellose. Die Gruppe der Wirbeltiere erscheint in den Vorstellungen der Schulkinder überrepräsentiert, während die artenreiche Tiergruppe der Wirbellosen vergleichsweise unterrepräsentiert ist. Das legt ein mangelndes Bewusstsein für Wirbellose bei Grundschulkindern nahe.

Resource allocation, scheduling and auto-scaling algorithms for enhancing the performance of cloud using Grey Wolf Optimization and Fuzzy rules
Authors: George Fernandez I. , Arokia Renjith J.
Published: October 2020

Cloud computing technology is playing a major role in the industry and real-life, for providing fast services such as data sharing and allocating the cloud resources that are paid and truly required. In this scenario, the cloud users are scheduled according to the rule-based systems for attempting to automate the matching between computing requirements and resources. Even though, the majority auto-scaling algorithms only helped as indicators for simple resource utilization and also not considered both cloud user needs and budget concerns. For this purpose, we propose a new model which is the combination of auto-scaling algorithms, resource allocation and scheduling for allocating the appropriate resources and scheduled them. This model consists of three new algorithms namely Grey Wolf Optimization and Fuzzy rules based Resource allocation and Scheduling Algorithm (GWOFRSA), Auto-Scaling Algorithm for Cloud based Web Application (ASACWA) and Auto-Scaling Algorithm for handling Distributed Computing Tasks (ASADCT). Here, we introduce new auto-scaling algorithms for enhancing the performance of cloud services. In this work, the optimization technique is used to predict the cloud server workload, resource requirements and it also uses fuzzy rules for monitoring the resource utilization and the size of virtual machine allocation process. According to the workload prediction, the completion time is estimated for each cloud server. The experiments are conducted by using a simulator called CloudSim environment of Java programming and compared with the existing works available in this direction in terms of resource utilization and enhance the cloud performance with better Quality of Service of Virtual Machine allocation, Missed Deadline, Demand Satisfaction, Power Utilization, CPU Load and throughput.

Investigation of Beam Features of Unidirectional Rayleigh Waves Electromagnetic Acoustic Transducers (EMATs) by a Wholly Analytical Solution
Authors: Xie Yuedong , Yin Wuliang , Xu Lijun
Published: October 2020

Electromagnetic acoustic transducers (EMATs) are widely used in industries due to its non-contact nature. This paper investigates the beam features of unidirectional Rayleigh waves EMATs, especially the effect of the wire length on beam directivity. A wholly analytical model is developed to calculate the Lorentz force distribution and ultrasound displacement distribution. The modelling results indicate that, compared to the coil consists of shorter wires, the coil consists of longer wires results in a narrower bandwidth of main lobe of unidirectional Rayleigh waves, which means the ultrasound are more concentrated. This study can be used for unidirectional Rayleigh waves EMATs design and optimization.

Published: October 2020

The industrial component under loading change its mechanical characteristics by stress. It is very important to make clear the distribution of the applied stress in the component to reduce the failure. In this paper, magnetic Barkhausen noise (MBN) method is used to evaluate the stress of DC01 steel. Combined with theory for both magnetic domain and magnetization, this work analyzed MBN signal from energy point of view. Magnetic strength corresponding to the maximum MBN shows a downward trend with the increase of tensile stress. Plots of energy against stress showed a relationship providing a convenient method for detecting stress levels by MBN.

Authors: Li Zibo , Li Shicheng , Wang Donghao , Sun Guangmin , He Cunfu , Li Yu , Liu Xiucheng , Cai Yanchao , Wang Chu
Published: October 2020

Barkhausen noise (BN) is electromagnetic pulse sequence that could be used to nondestructively predict the properties of materials such as hardness, residual stress and carbon content. Current BN signal analysis methods fail to describe the highly variated BN signal and achieve high regression accuracy due to the low interpretability of neural network and limited capacity of mathematical regression tools. In this paper, two multi-variable regression tools, named partial Chebyshev polynomial regression (PCPR) and Mutual Information-based Feature Selection with Class-dependent Redundancy and multi-variable Chebyshev polynomials regression (MIFS-CR+MCPR), are employed for the first time to predict the hardness of Cr12MoV steel (i.e. X12m). Combined with Chebyshev polynomials, our regression tools are designed on the basis of cascaded regression and mutual-information-based feature selection. As represented by the experimental results for predicting the hardness of X12m, the proposed method outperforms other comparative methods including neural network and partial linear square regression method.
Sensitivity Analysis for the Inverse Problems of Electromagnetic Nondestructive Evaluation
Authors: Bilicz Sándor
Published: October 2020

Sensitivity analysis of the model-based inverse problem associated to electromagnetic nondestructive evaluation is dealt with. Some uncertainty of the arrangement is inevitable present (imprecise host material parameters, sensor mispositioning, etc.), and this induces uncertainty on the reconstructed defect parameters. The aim of this work is to present a methodology for the ranking of the different sources of random error according to their contribution to the reconstruction uncertainty. To this end, state-of-art mathematical tools of sensitivity analysis are applied, including Sobol’ indices, and a polynomial chaos expansion surrogate model to reduce the computational burden of the method. A numerical example drawn from magnetic flux leakage nondestructive evaluation is presented to illustrate the proposed methodology.
Fractal scaling and crack-size effects on creep crack growth
Authors: Carpinteri Alberto , Niccolini Gianni , Rubino Alessio
Published: October 2020

Scaling effects on the creep crack growth behaviour are investigated by analyzing the results of compact tension (CT) tests on different-sized notched steel specimens appearing in the literature. Creep crack growth rate data are correlated to the elastic stress-intensity factor in terms of a Paris-type law, da∕dt = C0Kq, where C0 turns out to be a crack-size dependent coefficient of proportionality. Considering specimens with the same loading configuration (CT) and the same thickness, the observed crack-size effect on the creep crack growth rate is discussed on the basis of self-similarity considerations, and geometrically interpreted in terms of fractal tortuosity of the crack profile. A size-independent formulation of the creep crack growth law correlating renormalized quantities is finally deduced and confirmed by the experimental results.

BACKGROUND:

Dual-energy breast CT reconstruction has a potential application that includes separation of microcalcification from healthy breast tissue for assisting early breast cancer detection.

OBJECTIVE:

To investigate and validate the noise suppression algorithm applied in the decomposition of the simulated breast phantom into microcalcification and healthy breast.

METHODS:

The proposed hybrid optimization method (HOM) uses a simultaneous algebraic reconstruction technique (SART) output as a prior image, which is then incorporated into the self-adaptive dictionary learning. This self-adaptive dictionary learning seeks each group of patches to faithfully represent the learned dictionary, and the sparsity and non-local similarity of group patches are used to enforce the image regularization term of the prior image. We simulate a numerical phantom by adding different levels of Gaussian noise to test performance of the proposed method.

RESULTS:

The mean value of peak signal-to-noise ratio (PSNR), structural similarity (SSIM), and root mean square error (RMSE) for the proposed method are (49.043±1.571), (0.997±0.002), (0.003±0.001) and (51.329±1.998), (0.998±0.002), (0.003±0.001) for 35 kVp and 49 kVp, respectively. The PSNR of the proposed method shows greater improvement over TWIST (5.2%), SART (34.6%), FBP (40.4%) and TWIST (3.7%), SART (39.9%), FBP (50.3%) for 35 kVp and 49 kVp energy images, respectively. For the proposed method, the signal-to-noise ratio (SNR) of decomposed normal breast tissue (NBT) is (22.036±1.535), which exceeded that of TWIST, SART, and FBP by 7.5%, 49.6%, and 96.4%, respectively. The results reveal that the proposed algorithm achieves the best performance in both reconstructed and decomposed images under different levels of noise and the performance is due to the high sparsity and good denoising ability of minimization exploited to solve the convex optimization problem.

CONCLUSIONS:

This study demonstrates the potential of applying dual-energy reconstruction in breast CT to detect and separate clustered MCs from healthy breast tissues without noise amplification. Compared to other competing methods, the proposed algorithm achieves the best noise suppression performance for both reconstructed and decomposed images.

Щороку частота виявлення ГЦК невпинно зростає. У період з 1990 по 2015 рік показник вперше діагностованих випадків ГЦК збільшився на 75%. В Україні за 2018 рік спеці- альним лікуванням охоплено лише 18,0% первинних хворих: тільки хірургічним лікуванням - 4,9%, комбінованим та комплексним лікуванням — 2,0 %. Незадовільні результати з охоплення спеціальним лікування пов'язані з особливостями етіопатогенезу ГЦК, асимптоматичним пе- ребігом та недосконалою системою скринінгу пацієнтів групи ризику, що утруднює діагнос- тику захворювання на ранніх стадіях. Вибір тактики лікування ГЦК асоційованою з вірусним гепатитом і цирозом печінки досі залишається складною клінічною проблемою, оскільки “за- стосування радикального лікування на ранній стадії є наріжним каменем для покращення за- гальної виживаності таких пацієнтів. Пацієнтам з ГЦК на ранніх стадіях з цирозом печінки, що не підлягають радикальному хірургічному лікуванню на момент звернення, показано засто- сування методів перкутанної абляції — радіочастотна абляція, хімічна абляція, кріоабляція, мікрохвильова абляція тощо. Основними показаннями для застосування локальної абляції в лікуванні ГЦК — дуже рання та рання стадія (за BCLC – стадія 0 та А), компенсована або субкомпенсована функція печінки при цирозі (Child - Pugh клас A та B), загальносоматичний статус за ECOG 0–1, діаметр пухлинного вогнища до 5,0 см (найбільш оптимально до 3,0 см), вогнищеве вузлове ураження, солітарне або множинне ураження. Перкутанну абляцію застосо- вують у якості “брідж”-терапії з метою локального контролю пухлинного росту у пацієнтів, що відповідають Міланським критеріям, критеріям UCSFC і знаходяться в списку очікуван- ня на трансплантацію. Також дані методи показали свою ефективність як неоад'ювантна “downstaging”-терапія у хворих, що не відповідають критеріям для трансплантації печінки та/або з первинно нерезектабельним ураженням. Протягом багатьох десятиліть перкутан- на хімічна абляція була “золотим” стандартом мініінвазивного лікування ГЦК. Даний метод простий у виконанні, не потребує спеціального обладнання, добре переноситься пацієнтами, безпечний та економічно вигідний. Основні хімічні агенти - етанол та оцтова кислота. Про- цедура перкутанної хімічної абляції передбачає інтратуморальне введення хімічного агенту “real-time” під контролем методів візуалізації (УЗД або КТ). Хімічна абляція - це метод дру- гої лінії і застосовується лише у випадках, наявності протипоказань до виконання радіочас- тотної абляції. Даний метод не супроводжується тяжкими специфічними ускладненнями та летальністю. Ефективність її клінічного застосування безпосередньо залежить від розміру пухлинного вогнища. Оптимальний розмір пухлинного вогнища становить не більше 3,0 см. Інтратуморальне введення етанолу призводить до некротизації 90% -100% пухлинних вузлів ГЦК діаметром ≤ 2,0 см та 70% при пухлинах 2,0 - 3,0 см.
ОСОБЛИВОСТІ ДІАГНОСТИКИ ТА ЛІКУВАННЯ СПОРТИВНОЇ ГРИЖІ: ОГЛЯД ЛІТЕРАТУРИ

Спортивна грижа є надзвичайно актуальною проблемою в професійному та аматорському спорті. Актуальність дослідження даної патології обумовлена тим, що на даний момент не існує єдиної класифікації, немає чіткого алгоритму діагностики та ефективного загальноприйнятого хірургічного лікування. В статті проведена систематизація літературних джерел та підходів до вирішення проблеми болю в пахвинній ділянці при фізичних навантаженнях, що є основним проявом спортивної грижі у футболістів. Представлені результати досліджень свідчать, що характерною ознакою спортивної грижі є наявність слабкості задньої стінки пахвинного каналу без наявності анатомічних ознак типової грижі, а для верифікації діагнозу важливе значення має ультразвукове дослідження та магнітно- резонансна томографія пахвинної ділянки. В дослідженні проведено порівняльний аналіз результатів хірургічного лікування спортивної грижі. Результати проведеного дослідження можуть бути корисними для загальних хірургів, спортивних лікарів, сімейних лікарів, ортопедів-травматологів
