What do researchers cite in their Literature Review sections? An exploratory study of citations in Information Systems research articles
Authors: Chan Hon Tung , Kwan Siu Chu
Published: December 2022

The Literature Review (LR) section is an integral part of a research article (RA) where the author needs to develop a theoretical groundwork to anchor his/her own study. However, the part-genre always eludes novice writers, which involves deciding what to cite from relevant past literature and what goals the cited knowledge serves therein. Insights are thus necessary into how experienced/expert writers address such issues. Unfortunately, there has been a dearth of research into this topic, with existing work focusing mainly on the formal features and generic functions of source use. Motivated by the missing gap and the pedagogical need and grounded in Swales’s (1990) CARS model and Authors’ (2014) semantic typology of citations, the present study is an attempt to examine the semantic attributes of source ideas that get cited in different parts of the LR sections of Information Systems RAs following a behavioral science research (BSR) paradigm. Findings reveal that distinct types of source ideas are cited, which are associated with the specific move-steps of the LR sections and the BSR paradigm. A comparison of some of the cited ideas with the original ideas from the source texts also demonstrates that the latter have been re-contextualized to varying degrees to advance the arguments that the writers make in their LRs. Taken together, the study’s outcomes suggest that using a move-specific approach to citations can yield useful insights into source use in LRs. Implications for citation teaching and future citation research will be drawn.

Reflexiones acerca de las cambiantes narrativas sobre las vacunas contra la COVID-19
Authors: Silva Ayçaguer Luis Carlos , Bloch Silva Andrés
Published: December 2022

Nos propusimos discernir en qué medida las estrategias mediáticas adoptadas en torno a las vacunas contra la covid-19, a lo largo de los primeros 15 meses desde el comienzo de su aplicación, pueden considerarse aportes legítimos y coherentes para comprender mejor su desempeño, y en qué grado las narrativas elaboradas pudieran responder a intereses económicos de las élites corporativas. Una vez recopilados los elementos más relevantes con que se configuran las narrativas predominantes desde el momento en que se concibieron las vacunas, se identificaron diversas anomalías que resultaron, en mayor o menor medida, invisibilizadas en el proceso de su aprobación y de los resultados de su aplicación. Las más significativas conciernen al manejo de las definiciones, los incumplimientos de compromisos y los conflictos de interés que comprometen la actuación de las empresas comercializadoras y los entes reguladores de las vacunas. Numerosos elementos relacionados con los intereses corporativos han gravitado en la elaboración del relato sobre las vacunas. Entre los que reclaman resignificación se hallan: su capacidad preventiva real de contagios, evoluciones graves y muertes, su eficacia ante nuevas variantes, la duración de la inmunidad que confieren, sus efectos adversos, el papel sinérgico de la inmunidad adquirida y los recursos empleados por las empresas para conseguir un predominio virtualmente monopólico en el mercado

Objective: to describe the process of creation of the Permanent District Chamber of Mediation in Health (Camedis, in Portuguese) from the perspective of institutional actors; to understand the articulations for the realization of the right to health and the ways in which actors have tried to overcome institutional failures and barriers to access Brazilian Unified Health System (SUS, in Portuguese) Methods: a semistructured script was used to conduct interviews with key actors, and content analysis was conducted according to thematic categories. Results: analysis revealed that while interviewees thought the chamber was successful, it had limited success in reducing the judicialization of health care. Weaknesses identified included lack of regulation, structure, staffing, and adequate materials, resulting in a lack of monitoring of agreements reached and political-institutional support for stakeholders. The greatest strength was the high percentage of agreements and articulation between the actors involved. Conclusion: considering the successful potential of the Chamber, its redesign is recommended, with investment in human resources, its own infrastructure suitable for permanent operation, the establishment of clear commitments between participants in the fulfillment and monitoring of requirements, eligibility criteria and processes of management, greater transparency, resolution and expansion of the service so that the Chamber can be for all.

Published: December 2022

Objective: to identify topics related to the health of people deprived of liberty in Brazil that are covered in scientific journals and compare them with the guidelines of the current National Health Care Policy for Liberty Deprived People in the Prison System (PNAISP, in Portuguese). Methods: this was an integrative literature search conducted in the Virtual Health Library, National Library of Medicine, and Scopus databases, resulting in 37 selected articles. Results and discussion: the topics addressed in the articles related to the health of people deprived of their liberty in Brazil were based on a curative perspective with a focus on infectious diseases, with few studies on health promotion interventions. Most studies addressed guideline control and/or reduction of the most common diseases, to the detriment of the other guidelines of the PNAISP. Conclusion: overcoming the curative perspective in prisoner health care requires the promotion of health-promoting interventions that strengthen the implementation of the Brazilian Prison Health Policy guidelines. This study contributes to the reflection on prison health by recognizing the structuring guidelines of the PNAISP.

Resin-based composites represent a unique class of restorative dental materials; however, these composites have severe shortcomings such as low wear resistance which is mainly responsible for the short life-span of the materials. Composites characteristics such as strength, stiffness, resistance to abrasion, polymerisation shrinkage, thermal expansion coefficients and moisture absorption depend on the filler particles and coupling agents used. Fortunately, these composites have been the focus of attention for numerous researches in recent years which aim to improve the performance of the restorations in several ways. Using several types of coupling agents, and different particle sizes and types have gained the great interest of researchers. The latter plays a critical role in the toughening mechanisms in resin-based composites. Therefore, the purpose of this review is to discuss the literature regarding the toughening mechanisms in particulate dental resin composites since these mechanisms are also crucial factors for the improvement of mechanical properties. The four main types of toughening mechanisms discussed are: crack deflection, pinning, bridging and particle-matrix interface. The current review indicates an improvement in mechanical properties of particle-filled dental composites due to the presence of various toughening mechanisms. The dental resin composites’ fracture toughness is mainly contributed by crack deflection, pinning and bridging that take place in micro- and nanocomposites, in addition to the hybrid composites. Filler–matrix interphase plays an important role in improving the mechanical properties, in addition to its positive effect on crack deflection and bridging. In reality, all these mechanisms could occur simultaneously at different intensities, respectively.

Published: December 2022

Left ventricular segmentation from cardiac images has high impact to have early diagnosis of various cardiovascular disorders. However, it is really a challenging task to segment left ventricular images from magnetic resonance image (MRI). In this paper, we explore several state-of-the-art segmentation algorithms applied on left ventricular (LV) segmentation on cardiac cine-MR images. Both adaptive and global thresholding algorithms along with region-based segmentation algorithm have been explored. Edge-based segmentation is disregard due to the absence of edge information in the employed dataset. For evaluation, we explored a benchmark dataset that was used for the MICCAI 3D segmentation challenge. We found that the cardiac MRI global thresholding has proved to be much efficient and robust than the adaptive thresholding. We achieved more than 92% accuracy for global thresholding, whereas, about 78% accuracy for the adaptive thresholding approach. The use of entropy or histogram to characterize segmentation in place of the intensity value of the pixel has a vital effect on segmentation efficiency. It is evident that the intensity information is corrupted by acquisition procedure, as well as the structure of organs. Due to the lack of boundary information in cardiac cine-MRI, clustering and region-based segmentation have produced more than 93% segmentation accuracy. For the case of soft clustering, the increased accuracy is found as 96%. However, more explorations are required, specially based on deep learning approaches on very large datasets.

Rheology can be defined as the primary measurement associated with bitumen flow and deformation characteristics. In the long term, DSR testing consumes a long time, expensive cost and skilled labour to operate equipment or machines in the laboratory. The complex modulus, G* and phase angle, δ, are essential parameters for characterising and predicting the rheological behaviour of unaged bitumen (UB) and polymer-modified bitumen (PMB) in the model. This study developed three regression models using Azure machine learning (AML) to predict the rheological behaviour of UB and PMB. There are three types of data used as input data to develop the regression model: temperature, frequency, and modified material content. Regression models were developed with three processes or steps that need to be prioritised: data collection, model preparation, and model validation. Algorithms used in model development are decision tree regression (DFR), boosted decision tree regression (BDTR) and linear regression (LR). The results show G* and δ values. The R2 values in the G* and δ predictions obtained from the DFR models are 0.8199 and 0.9480, respectively. Moreover, the R2 values in the G* and δ predictions obtained from the LR models are 0.4219 and 0.7836, respectively.

Conventional screw press fish pelleting machines are commonly used as a method of producing fish feed, but often affect the product properties. Manual pelletizers using hydraulic press instead of screw in a cassava flour-based diet can be easily processed, which can improve handling and storage. The influence of the pelletization parameters on some properties of cassava-based pellets was the focus of this study. The conditioning factors analyzed were: die size (4, 6 and 8mm), temperature (30, 60 and 90oC), cassava inclusion (5, 10, 15 and 20%) and the influence of the mash moisture content (35, 40 and 45%) on the process and product responses. The quality of the pellets was evaluated in view of current standards. Second-order polynomials were applied to demonstrate the responses as a function of process factors. The studied factors had significant effects on the process response (throughput) and pellet properties (durability and bulk density). Majority of the values of throughput, bulk density and durability of the produced pellets attained the standard limits. Pelletizer operated optimally with processing parameter at 6.0 mm die size, 60°C temperature, 40% moisture content and 20% cassava inclusion rate resulted in pellet temperature (64.4°C), moisture content (34.21%), throughput (932.26 g h-1), bulk density (0.36 g cm-1), durability (99.1%) and hardness (0.30 kN). Pelleted feed using a manual press device under high cassava containment improves the properties of the product. Therefore, the applicability of the response surface method to optimize the process variables is sufficient.

A comprehensive review of the current level of research in the development of intelligent hybrid nanosystems based on porous inorganic materials, in particular porous alumina, has been carried out. Porous materials are of great interest for the development of controlled drug delivery platforms due to their high effective surface area and controlled pore size. One of the main determinants of the overall pore drug loading and release profile is pore geometry. Three-dimensional pore structures with complex pore geometries and increasing surface area are promising platform designs for sustained drug release. But there are certain structural and financial difficulties in their manufacture. Porous anodic alumina, which is easily and economically produced by electrochemical anodization, allows complex and reproducible three-dimensional pore geometries to be obtained. The unique physical and chemical properties of porous anodic alumina make this material a promising platform for controlled drug release. Porous anodic alumina has a highly ordered pore distribution, and its well-known electrochemical fabrication methods allow precise control of pore spacing, diameter, length, and pore geometry. The purpose of this work is to analyze the current level of research in the development of intelligent hybrid nanosystems based on porous alumina with different characteristics for use in medicine. The presented works have shown interesting opportunities for the development of intelligent, multifunctional optical devices with a microchip design. The design of implantable biosensors with the ability to monitor biological systems in vivo and in real time is promising for the use of porous anodic alumina immunosensors.
METHODOLOGICAL APPROACHES TO STUDYING THE CONCEPT OF JUSTICE IN THE LATIN LANGUAGE
Authors:   Taras Shevchenko National University of Kyiv, Pysmenna Iuliia
Published: December 2022

The article is concerned with methodological approaches to the study of the concept of JUSTICE in Latin and determines the main ways of development of its semantics. The words that express the idea of justice in Latin are iustitia and aequitas. Dictionary definitions and functional fields of lexemes are analyzed. Iustitia in legal discourse is defined as a virtue that gives suum cuique «to each his own» (Iustiniani Digesta), personifies legality and justice in judicial practice and lays the foundation for the further development of the Western European law system. In the context of political life, the cult of Iustitia became widespread in the Octavian era as an important part of the political ideology of Emperor Augustus. The use of iustitia in social and political discourse changes the meaning of the term, which becomes the foundation for the absolute power of the emperor as a guarantor of justice and a source of legal norms. The rationalistic and early humanistic conception of iustitia arises in the philosophical and empirical reflections of Cicero. Common ethics and morality, reflected in proverbs, deal with justice through the idea of mutual service as the basis for social balance in business and personal relations.

Published: December 2022

There are roughly 4000 AYUSH hospitals spread out across India under various councils and hospitals run by the Indian government. Today’s atmosphere makes it more challenging than ever to locate a suitable AYUSH facility for the treatment. The AYUSH Ministry provides India’s top option for healthcare delivery. The government is examining strategies to lower expenditures while enhancing patient care. We are proposing the ground-breaking idea of e-healthcare which involves various novel features like suggesting various tools to the patients those need to communicate with the healthcare professionals as per their convenience remotely. This research suggests an interactive system using Android in line with this trend. By integrating different bio-medical data sources that contain information pertinent to the hospital demographics, their inpatient procedure rates, Outpatient department, etc., we proposed a system that surveys on the various AYUSH hospitals to find. This system uses the Google Map API for tracking and highlighting the location to the nearby AYUSH hospitals with opening and closing timings. Additionally, the proposed system plays a crucial role in emergency scenarios by supporting the user in performing the necessary first aid techniques. Using this strategy, the entire system demonstrates that this research provides a superior method for making decisions than past studies.

Authors: Zykin Andrey A. , Gerasimov Sergei A. , Gorbatov Roman O. , Illarionova Tat’yana V.
Published: December 2022

Background. The presence of extensive bone defects significantly complicates the possibility of stable fixation and correct spatial positioning of the revision endoprosthesis components. The primary task of revision surgery is to restore the lost bone. The use of modern implants makes it possible to replace large metaphyseal defects of the tibia and femur, including AORI type 2B и 3 bone defects.
The aim of the study was to evaluate the long-term results of surgical treatment of patients with extensive bone defects (2B and 3 according to AORI) of the proximal tibia and/or distal femur using custom-made implants for revision knee arthroplasty.
Methods. A retrospective clinical study was performed in 24 patients who underwent revision arthroplasty using individual implants (9 femoral and 18 tibial) made on a 3D printer in the period from 2017 to 2021. T3 defect according to AORI classification was diagnosed in 12 patients (50%), F3 defect in 1 (4.17%), F2B in 8 (33.3%), T2B in 6 (25%). All patients before surgery and 3, 6, 12 months after surgery were surveyed according to the international scales VAS, KSS, WOMAC and SF-36.
Results. At the follow-up examination 12 months after the surgery, 9 out of 24 patients (37.510%) walked without additional means of support, 10 out of 24 (41.710%) with a cane, 4 out of 24 (16,78%), walkers 1 out of 24 (4.210%). There were no periprosthetic fractures during surgery and in the postoperative period. When evaluating the functional state of the knee joint, an excellent result was registered in 45.810% and 33.310%; good in 37.510% and 54.210%; satisfactory in 16.678% and 12.57% according to the KSS and WOMAC scales, respectively. When assessed on the VAS scale, there was a positive trend in the form of statistically significant decrease in pain in all patients (p0.01).
Conclusion. The use of individual implants made using additive 3D printing technologies in revision knee arthroplasty in the presence of extensive bone defects (2B and 3 according to AORI) allows to perform an organ-preserving surgery without loss of the statodynamic function of the lower limb. This study has limitations due to the small sample size. We believe that it is promising to study the long-term results of surgical treatment of patients with extensive bone defects (2B and 3 AORI) of the proximal tibia and /or distal femur using individually manufactured implants for revision knee replacement and a comparative analysis of these results with those using conventional implants.

Published: December 2022

Ground-motion studies are a key component of seismic hazard analyses and often rely on information of the source, path, and site. Extensive research has been done on each of these parameters; however, site-specific studies are of particular interest to seismic hazard studies, especially in the field of earthquake engineering, as near-site conditions can have a significant impact on the resulting ground motion at a site. There has been much focus on the constraint of site parameters and their application to seismic hazard studies, especially in the development of ground-motion models (GMMs). Kappa is an observational parameter describing the high-frequency attenuation of spectra, and its site contribution (κ0) has shown to be a good predictor of high-frequency ground motions; however, measurements are often limited. In this study, we develop a κ0 dataset for the San Francisco Bay area (SFBA) by estimating κ0 for 228 stations, and we produce a continuous regional map of κ0. We find κ0 to range between 0.003 and 0.072 s, with larger values concentrating on the east, north, and south sides of the bay, and lower values concentrating on the west side. We also evaluate the robustness of κ0 as a site parameter and find it to correlate with peak ground acceleration. These estimates of κ0 can add predictive power to GMMs, thus increasing the accuracy of predicted ground motion and improving the robustness of ground-motion studies in the SFBA.

Sciatic nerve (SN) injury associated with total hip arthroplasty (THA) is a challenging issue due to the high prevalence of the complications. However, there is no consensus about the injury mechanism, surgical treatments, indications and timing for the surgeries which necessitates the studies. The objective was To perform a comparative analysis of the dynamics in clinical, neurological and electrophysiological parameters in patients with sciatic nerve injuries associated with THA performing various surgical treatments. Material and methods The study included 61 patients who were hospitalized between 2005 and 2021. Patients were divided into two groups being homogeneous in terms of gender, age and severity of neurological deficit. Microsurgical neurolysis of the sciatic nerve trunk was performed in group I (n = 32) and was added by direct electrical stimulation of the sciatic nerve at the level of injury in group II (n = 29). Clinical, neurological status and electroneuromyography parameters of the patients were assessed preoperatively and at 6 months of surgery. Results All patients showed pain relief with VAS score decreasing from 6 (5.5; 8) to 4 (2; 6) in group I and to 3 (1; 5) in group II (p < 0.001). Functionality of the lower limb scored preoperatively 31 (24.5; 40.5) on the ODI scale in group I and 27 (21; 36) in group II. The patients showed positive dynamics postoperatively with improved lower limb function due to decreased neuropathic pain syndrome scoring 28 (20; 34.5) in group I and 16.5 (8.5; 21.75 ) in group II (p < 0.0001). Conclusions The findings suggested the advantages of the electrical stimulation method in combination with microsurgical neurolysis of the sciatic nerve over the use of microsurgical neurolysis alone with decreased intensity of the pain syndrome and functional insufficiency of the lower limb.

Introduction Causes of aseptic loosening of THA components and improvement of the implants remain the subject of scientific discussions. The objective was to perform comparative analysis of the results of biomechanical modeling of cementless total hip arthroplasty using implants with different stem neck-shaft angles as a prerequisite of aseptic loosening of the acetabular component. Material and methods A biomechanical model of the pelvis and an implant with different stem neck-shaft angles was constructed based on computed tomography findings. Stresses and strains that the patient typically experienced under full weight-bearing on the operated lower limb were explored. Results The use of a stem neck-shaft angle of 125° provided the most favorable localization of the contact patch at the border of the acetabular component – the pelvic bone and lower values of equivalent stresses and contact pressure in comparison with more "valgus" femoral components (135° and 145°). Discussion The data obtained were fully consistent with the results of biomechanical studies by L. Quagliarella et al. (2006) who reported the substantial significance of the neck-shaft angle for on the parameters of contact pressure, since wear and debris-associated osteolysis decrease with a decreased neck-shaft angle. The use of stem neckshaft angles equal to 125° can be indicated for young patients with good bone quality and equal lower limb length. Unstable femoral cup can be caused by eccentric position of the contact spot at the border of the bone and the acetabular component and distribution of contact pressure and equivalent stresses inside the spot that are typical for artificial joints with stem neck-shaft angle of 145°. Conclusion The findings suggested that the value of stem neck-shaft angle was likely be considered a prerequisite for aseptic loosening of the acetabular component.

Introduction Combined injury, as a cause of death, occupies a central place in different age groups and is common for individuals ages 50 and younger. Most sacral fractures are traditionally repaired with screw or plate. However, the fixation can be unreliable in atypical anatomy of the upper sacral segment, U-shaped and H-shaped fractures, compression of nerve structures and failed fixation. Material and methods Reported is a case of a 29-year-old patient who suffered a severe concomitant injury including comminuted fracture-dislocation of the sacrum complicated by caudopathy. Results A good clinical and anatomical result was obtained. She developed a complete regression of neurological symptoms. The patient could ambulate without additional support. The function of the pelvic organs was restored. Discussion For a comparison, two methods were presented: lumbopelvic fixation using two rods and a transverse buckle and triangular fixation with a rod and an additional iliosacral screw. Lumbopelvic fixation is a surgical procedure for unstable pelvic ring injuries that allows immediate weight-bearing. Biomechanical tests showed greater primary stability with triangular lumbopelvic fixation than iliosacral fixation with no stress to the injured area. Bilateral lumbopelvic fixation with a transverse buckle allowed secure fixation of the lumbopelvic junction for fracture healing, protection of the sacroiliac joints preventing the development of transitional kyphosis and maintaining the spine balance with careful surgical handling of the soft tissues.
La UCD y el PSD: Sinergias ibéricas en un centro-derecha en transición
Authors: Sabater Navarro Gregorio
Published: December 2022

La colaboración entre el centroderecha de España y Portugal durante las transiciones a la democracia adquiere su significado completo en el marco de lo que se denomina corriente de retorno de las transiciones ibéricas: periodo en que la Transición española, convertida en un referente de cambio político para buena parte de la opinión pública occidental a partir de 1977, comenzó a influir en la compleja realidad portuguesa del momento, en pleno reflujo posrevolucionario. El éxito de la Unión de Centro Democrático y la labor de los gobiernos de Adolfo Suárez —que al alimón con la oposición consiguieron importantes logros en los ámbitos político, económico y social— se convirtió en un referente para un PSD luso en pleno proceso de reubicación ideológica y lucha por el poder. De esta manera, las sinergias establecidas con la UCD constituyeron el principal apoyo exterior de la coalición Aliança Democrática, que supuso la llegada de la derecha al Gobierno de Portugal por vez primera tras la vuelta de la democracia.

Three-dimensional (3D) extrusion-based bioprinting is the most widely used bioprinting technology to fabricate bionic tissue or organ constructs by combining biomaterial ink and living cells for tissue engineering and regenerative medicine. One critical issue of this technique is the selection of suitable biomaterial ink to simulate extracellular matrix (ECM) that provides mechanical support for cells and regulates their physiological activities. Previous studies have demonstrated that it is an enormous challenge to form and maintain reproducible 3D constructs and eventually achieve the balance among biocompatibility, mechanical properties, and printability. This review highlights the properties of extrusion-based biomaterial inks and recent developments as well as details various biomaterial inks classified by their function. Key approaches related to their modification methods according to the functional requirements are also discussed, along with the selection strategies by varying extrusion paths and methods in extrusion-based bioprinting. This systematical review will assist researchers in identifying the most suitable extrusionbased biomaterial inks based on their requirements, as well as in elaborating current challenges and prospects of extrudable biomaterial inks in the field of bioprinting of in vitro tissue models.

Background: Allergic bronchopulmonary aspergillosis (ABPA) is a type of hypersensitivity reaction to mold Aspergillus fumigatus, especially common in patients with bronchial asthma. However, systemic data regarding the clinicodemographic, radiological, and immunological profiles of patients is sparse, particularly from the eastern India.Methods: This is a prospective observational study done over a year, from January 2021 to December 2021, in patients visiting the pulmonary medicine outpatient department (OPD) with symptoms similar to ABPA. Following the clinical examination, routine blood investigations, serum total immunoglobulin E (IgE) test, Aspergillus-specific IgE test, spirometry, and chest radiology (chest X-ray/high resolution CT scan) were done. ABPA was diagnosed using the 2013 ISHAM-ABPA working group criteria. Data were analyzed using statistical package for the social sciences (SPSS) software version 2021 against different categories of eosinophil count.Results: A total of 99 patients, 74 male and 25 female, were diagnosed with ABPA. The mean age±standard deviation (SD) was 37.66±15.411. Most of the patients (93) were asthmatic. Chest radiology was normal in 52.5% of the cases. The absolute eosinophil count (mean±SD) was 3963.61±5333.363. The mean±SD serum IgE and Aspergillus-specific IgE levels were 8061.07±8374.274 and 7.5826±12.693, respectively.Conclusions: There was no significant association between lung function abnormalities and eosinophil count. Serology variant (ABPA-S) was the most common finding among ABPA patients. A high eosinophil count was associated with a high incidence of bronchiectasis and hyper attenuated mucus (HAM), although the severity of bronchiectasis was not directly related to a higher peripheral eosinophil count. There may be some correlation between the peripheral eosinophil count and the total IgE but not between the peripheral eosinophil count and the Aspergillus-specific IgE.

Published: December 2022

Background: Multisystem inflammatory syndrome in children (MIS-C) is temporally associated with SARS CoV 2 infection with a possible immune dysregulation. Presents with a multi organ involvement with dreaded complication of LV dysfunction and a long term sequalae of coronary involvement.Methods: Prospective observational study of a cohort of 35 patients who fulfilled the CDC criteria for MIS-C. Demographic, clinical, lab, echocardiographic, treatment and outcome details were noted and analysed.Results: The 35 children fulfilled CDC definition of MIS-C. Fever was present in 100% cases, rash in 62%, diarrhoea in 57%, RTI in 43%, hypotension in 43% and lymphadenopathy in 19% cases. The 23 patients had moderate MIS-C and 12 patients had severe MIS-C on admission. The 38% had normal contracting heart, 19% had dilated coronaries, 17% had mild LV dysfunction,12% had moderate LV dysfunction,12% had severe LV dysfunction, two patients had prolonged PR interval, one patient had AV block. Four patients had acute kidney injury; one patient had brachial vein thrombosis. 52% patients received combination of methylprednisolone and IVIG while 48% received only methylprednisolone. Defervescence was earlier in IVIG+MPS group compared to MPS group (1.72 days vs 2.8 days [p<0.05]). Improvement in LV dysfunction was earlier in IVIG+MPS group compared to MPS group (33 hours vs 40 hours, p<0.05). At 3 months followup Z score of coronaries was 1.9 (SD=0.125) in LMCA and 1.8 (SD=0.1) in LAD.Conclusions: Patients treated with IVIG+MPS had better outcome compared to MPS only. Older children had more severe disease presentation. Coronary artery dilatation tends to improve with time.

Background: This study is looking at the daily life consequences of hearing loss in older adults, and how hearing aids (HA) can affect their lives.

Method: Everyone who took part in the study had their hearing checked using basic tests. The McCarty Alpiner scale is a way to measure how much personal affection someone has. The Arabic international outcome inventory for hearing aids was used to measure the benefits of using hearing aids.

Results: There was a moderate correlation between hearing measurements without hearing aids and psychological, social, and vocational affection. The hearing aid improves your ability to hear, and the better your hearing gets, the higher your hearing threshold will be. However, there is no correlation between age and gender, and this is mainly due to differences in how hearing is processed in males and females. The improvement in the audiological profile of the patient suggests that their personal outcome will be better.

Conclusions: Daily life consequences of hearing loss and general life Satisfaction are closely related. Hearing aid is a beneficial rehabilitation method for presbycusis.
