Published: April 2022

The difficulty of practical media makes educators not innovate in the learning process, especially in delivering subject matter. Even though the technology is beneficial for this, one of which is the Smart App Creator application. Smart App Creator is very easy to use by educators because this application is a user interface; easy to understand. This research was conducted to determine the benefits of a Smart App Creator software in making learning media. This research method was qualitative with a library model; analyzed national and international journals and interview models; interviewed three teachers and nine students at different Islamic junior high schools. The results of this study explained that learning media designed using Smart App Creator software can provide motivation and foster enthusiasm for learning of students because this software contains elements of text, audio, video, and animation that are combined in one media; what's interesting is that this application can be opened. On a laptop or computer without installing the main application and can also be installed on an Android smartphone and has the advantage of not being connected to the Internet.

Introduction: In Morocco, blood donation is voluntary, anonymous, and voluntary. The promotion of blood donation has evolved favorably thanks to strategies based on the creation of a multi-sector promotion system. The transformation of family donors into voluntary donors and the retention of voluntary donors is the major challenge of the national blood transfusion center.

Materials and methods: This is an analytical quantitative cross-sectional study on a target population made up of 1000 participants. The collection tool was a self-administered, anonymous questionnaire made up of closed questions concerning the socio-demographic profile of the participants, and their knowledge and attitudes about the blood donation operation as well as their motivation and limitations of the donation. The responses were collected and entered by a team of graduate students in sociology. Data were analyzed by SPSS 20 software.

Results: Among the 953 participants, their mean age (Standard Deviation) is 32.56 (12.993) years, with 63.4% of the participants under the age of 34 (n = 429). For data relating to blood donation, 69.3% of the participants thought they did not know the blood group (n = 660), more than 70% thought of the existence of the illegal sale of blood in Morocco (n = 668). 69.3% of the participants think they do not know the blood type (n = 660), more than 70%, though of the existence of the illegal sale of blood in Morocco (n = 668), 70.8% do not know someone who has had or require an organ or tissue transplant (n = 479).

Conclusion: The need for blood is sharply increasing. an enormous shortage hence the need for epidemiological study to highlight the various difficulties that hamper the promotion of blood donation.

Published: April 2022

Dendrimers are symmetric molecules; their size is within the nanoscale. Its structure is usually homogeneous and monodisperse; they are composed of a nucleus and several layers 1. The number of layers that the dendrimer has defines its generation. There are different types of dendrimers. The synthesis of these macromolecules is carried out following steps of growth and activation, and organic reactions are required to obtain their branched structure2. Although size is essential, the determining factor of toxicity in dendrimers is the charge of the surface; it has been found that the higher generation dendrimers and the cationic ones are the most toxic compared to the lower generation anionics that evaluated at low concentrations did not show any toxicity 3. The dendrimers will favor the pharmacokinetics of a drug through the dendritic structure, the generation of the dendrimer to be used, the intramolecular interaction force between the adjacent functional groups in the dendrimer, the conditions of the environment such as pH, solvent polarity, strength ionic, saline concentration or presence of counterions, among others 4. Due to dendrimers' size and surface composition, the use of dendrimers in drug delivery has been increasingly studied. There are different interaction mechanisms between drugs in dendrimers, and these can be broadly divided into simple encapsulation, electrostatic interaction, and covalent bonds 5. The use of dendrimers in ocular administration has greatly impacted the complexity of this administration route. Gene therapy has also benefited from the emergence of these molecules as it facilitates targeted therapy.

Objective:  The SARS-CoV-2 virus, which emerged in December 2019 in Wuhan, China, spread very quickly in a short time and was declared a pandemic by the World Health Organization in March 2020. Physiological and immunological changes during pregnancy cause complications in respiratory tract infections. Complications by COVID-19 lead to a systemic effect that causes maternal and fetal mortality and morbidity. In this study, we aimed to investigate histopathological changes and Ki-67 expression in placentas of women with positive COVID-19 infection.

Study Design: Placentas of 10 samples COVID-19 positive and 10 samples Covid-19 negative pregnant patients who were hospitalized in the Gynecology and Obstetrics Clinic of Dicle University Faculty of Medicine were included in the study. Placental tissues were fixed in 10% formaldehyde (24 hours) and processed for routine paraffin wax tissue staining. Hematoxylin Eosin dye and Ki-67 immunohistochemical staining were performed.

Results:  Decidual cell degeneration, increased numbers of syncytial nodes, dilatation in vessels, degenerated villi were observed in the placentas of COVID-19 positive pregnant women. COVID-19 damage regular histology of placental structures. Ki-67 expression was intensely increased in COVID-19 positive placentas compared to COVID-19 negative placentas.

Conclusion: We suggest that COVID-19 causes some abnormalities in the histology of placentas and cell death, which leads to new cell proliferation.

Minocycline abrogates lung oxidative damage and haematological perturbations in mice exposed to hypoxia
Authors: Eduviere Anthony , Otomewo Lily
Published: April 2022

Objectives: Hypoxia results from the unavailability of sufficient oxygen to tissues. Since previous studies have shown that hypoxia results in inflammation, this research has found it necessary to investigate the impact of chronic hypoxia on the lungs and blood of mice and also the potential benefit of minocycline which is a well-known antibiotic.

Design: Thirty mice were split into 5 groups of 6 animals each. A physical model of hypoxia was used. Here, mice were locked in a 250 mL airtight container for 20 mins each day for seven consecutive days.

Interventions: One hour before exposure to hypoxia, mice in all groups except the vehicle group, were treated with varying doses of minocycline (10, 20, 40 mg/kg, p.o.).

Main Outcome Measures: The mice in the positive control group expressed a sign of lung inflammation with an increase in myeloperoxidase activity, as well as lung oxidative stress with an increase of prooxidants over antioxidants. While in the blood, white blood cells were significantly increased whereas red blood cell count depreciated as blood volume did too.

Results: The various effects of hypoxia on the blood and lungs of the mice were significantly prevented and attenuated to an acceptable degree by minocycline

Conclusion: In conclusion, minocycline expresses an acceptable benefit in the respiratory and circulatory systems of mice in hypoxic conditions.

Published: April 2022

Pode-se afirmar que a população brasileira vem passando por alterações nos padrões dietéticos e nutricionais, caracterizado pelo aumento do sobrepeso e obesidade. Estes padrões também têm crescido em jovens, constituindo-se como um grave problema de saúde pública. Nesse sentido, a escola pode desempenhar um papel fundamental na prevenção desse processo, a partir da formação de hábitos alimentares saudáveis. Isso porque o conhecimento sobre os alimentos é inicialmente influenciado pela família e em seguida pela escola, onde em média as crianças consomem cerca de trinta por cento das calorias diárias. Assim, o profissional da educação pode ser um dos principais influenciadores de hábitos alimentares saudáveis, pois passa a maior parte do tempo com os alunos. Este trabalho tem por objetivo identificar escolhas alimentares de alunos e professores durante o lanche escolar e verificar se a partir dessas escolhas há influência e estímulo na promoção de hábitos alimentares saudáveis. Foram feitas observações das escolhas alimentares e atitudes dos professores durante o horário do lanche, de forma a verificar se há possíveis correlações entre o posicionamento dos professores e as escolhas dos lanches pelos alunos. A cada semana foi acompanhado um ano do ensino fundamental I, totalizando quatro semanas de observações. Ao final, os professores foram entrevistados e responderam a um questionário. Entende-se assim que cabe à escola promover trabalhos relacionados à educação alimentar e a implantação de projetos que previnam doenças, estimulando para isso a capacitação dos professores em temas envolvidos com nutrição, para o seu bom desempenho na saúde escolar.

Hacia un análisis de la Atención Primaria de Salud como dispositivo de biopoder
Authors: Macaya-Aguirre Gustavo Adolfo
Published: April 2022

La Atención Primaria de Salud en Chile (APS) forma parte central de la estrategia de salud pública del Estado chileno para el cuidado de la población. Al interior de la APS existen múltiples indicadores para medir las acciones sanitarias, tales como las Metas Sanitarias (MS) y el Índice de Actividad de la Atención Primaria de Salud (IAAPS). En esta línea, en el presente artículo busco reflexionar, desde una perspectiva foucaultiana, y a partir de un análisis de las MS e IAAPS, si es posible pensar la APS como un dispositivo de biopoder al interior de la salud pública chilena. Para ello, la investigación estará dividida en tres partes. En primer lugar, expondré los elementos centrales que componen las MS y el IAAPS, en segundo lugar, desarrollaré los conceptos de biopoder y dispositivo, presentes en el pensamiento foucaultiano y, en la tercera sección, realizaré análisis de las MS e IAAPS a partir de las claves comprensivas trabajadas en la sección anterior. Finalmente, el curso de los argumentos me lleva a sostener que las MS e IAAPS son estrategias centrales de biopoder presentes al interior de lo que he denominado dispositivo de atención primaria, cuyo objetivo es, por un lado, intervenir los cuerpos y, por otro, separar y priorizar ciertos grupos de la población y desplazar a otros.

Published: April 2022

Reflexionar sobre los modos de producción en el área de lo territorial, implica dar cuenta de la apropiación y pertenencia a un espacio que enmarca actividades productivas, materiales y simbólicas, así como de relaciones de poder y de sentido desde lo vivencial y lo institucional que convergen en un mismo lugar, como la vereda Mudara en el municipio de Supía, en el departamento de Caldas - Colombia. El propósito de este artículo es evidenciar las dinámicas socioproductivas alrededor de la producción de la caña panelera que generan procesos de cambio y continuidad. El método etnográfico permitió desde el trabajo in situ, el análisis de las narrativas y prácticas tanto cotidianas como institucionales. Los resultados dan cuenta de diferentes modos de producción alrededor del sistema productivo de la caña panelera: el tradicional, el comunitario y el empresarial, y estos, por un lado, muestran que persiste un modo de producción tradicional-familiar y, por otro, la existencia de estrategias de producción emergentes que contribuyen al desarrollo local de las comunidades campesinas; aspectos que inciden en la configuración productiva y social de los territorios rurales.

Mitogenomic phylogenetics of the wild silkmoth genus Samia Hübner, 1819 (Lepidoptera: Saturniidae)

Published: April 2022

The wild silkmoth genus Samia Hübner, 1819 (Saturniidae) contains a
number of economically important species in industrial silk production.
However, the interspecific relationships within the genus remain
unclear. We sequence the mitogenomes of Samia watsoni Oberthür, 1914 and
Samia wangi Naumann & Peigler, 2001. Both mitogenomes are annotated and
found to be cyclized, with 37 genes (13 PCGs, 2 rRNA genes and 22 tRNA
genes). Using maximum likelihood and Bayesian inference methods, we
analyze these mitogenomes together with a further 68 downloaded from
GenBank (65 Bombycoidea and 5 Lasiocampidae as the outgroup) to
investigate both the phylogenetic relationships both within the genus
and those among the three families of the ‘SBS’ group: Bombycidae,
Saturniidae and Sphingidae. The results show that within Samia, S.
ricini is closely related to S. canningi, and not S. cynthia of which it
has been considered a subspecies. Although arguments have been proposed
to treat S. ricini and S. canningi as conspecific, we choose to accept
the morphological arguments and continue to treat them as two separate
species. Samia watsoni is corroborated as the sister group of all other
Samia species, but nevertheless should be included within Samia rather
than being placed in its own monobasic genus. Our analysis recovers the
following relationship among the three families of the ‘SBS’ group:
(Saturniidae + (Bombycidae + Sphingidae)). This agrees with previous
studies based on analysis of mitogenomes but continues to contradict the
results derived from phylogenomic analysis of nuclear genomes.

Data screening based on correlation coefficient and deep learning for fault diagnosis of arc fault
Authors: Shang Tongtong , Wang Wei
Published: April 2022

The effective identification of series arc faults is of great
significance for preventing fires in residential buildings. Considering
the disadvantage that the fault features of the current signal are
hidden deeply and different correlation features and irrelevant features
are mixed in the current signal, which makes the training speed of the
learning algorithm slow and the recognition accuracy low, this work
proposes a method based on complete ensemble empirical mode
decomposition with adaptive noise (CEEMDAN) decomposition and
convolutional neural network (CNN). The CEEMDAN algorithm is used to
decompose the collected current signals. Then the IMF components with no
representational significance are eliminated by calculating the spearman
correlation coefficient before being fed into the CNN. We select five
different electric loads for experimental validation with various signal
characteristics, including heaters, induction cooktops, computers,
microwave ovens and vacuum cleaners. The experimental results show that
the proposed method has an accuracy rate of 95.23%. Therefore, it can
be used for serial fault arc recognition in residential building power
distribution systems.

Published: April 2022

The effect of zircon (ZrSiO4) on the physico-chemical and mechanical
properties of geopolymer/zircon composites was examined in this study. Four
geopolymer/zircon composites containing 10, 20, 30 and 40 wt.% zircon were
prepared from metakaolin with alkali activators. Characterization of the
obtained geopolymers was performed by X-ray diffraction (XRD), Scanning
electron microscope (SEM-EDS), Fourier transform infrared spectroscopy
(FTIR) and Matrix-assisted laser desorption ionization time-of-flight mass
spectrometry (MALDI-TOF). XRD results did not confirmed the formation of
interconnected phases between added zircon, starting aluminum silicates and
alkali activators. Compressive strength of prepared geopolymer was examined.
The maximum obtained compressive strength of 70.15 MPa was measured in
sample containing the smallest fraction of zircon, i.e., 10 wt.%. Addition
of larger amount of zircon (20 wt.%) hinders the progress of
geopolymerization reaction and consequently decreases compressive strength.
Effect of initial powder particle size on permeability and corrosion behavior of biomedical porous Ti6Al4V alloy prepared by powder metallurgy technique
Authors: Phuong Doan , van Luan , van Trinh , Trung Tran
Published: April 2022

In this work, the influence of initial powder particle size on the properties
of biomedical porous Ti6Al4V alloys prepared by the space holder method was
investigated. The results show that the particle size of the initial powders
has a strong impact on the permeability, mechanical properties and corrosion
behavior of the obtained porous Ti6Al4V alloys. When the mean particle size
increases from dm ~ 17 ?m to dm ~ 43 ?m, the permeability of the resulted
alloys increased about 47 folds, from 6.74?10-13 to 3.15?10-11 m2. On the
contrary, the yield strength and modulus decreased from 207 MPa and 4.52 GPa
to 98.1 MPa and 3.1 GPa, respectively. In this process, the macropores are
defined by the space holders, the micropores presented on the cell walls are
generated from partial sintering of powders which have an important role in
the enhancement of the connectivity between macropores, porosity and hence,
the permeability of porous materials. It is found that using the bigger
particles led to the higher corrosion current density, Icorr due to the
increase of the contact area with the simulated body fluid solution.

Authors: Castro AS , Maran BM , Gutierrez MF , Chemin K , Mendez-Bauer ML , Bermúdez JP , Reis A , Loguercio AD
Published: April 2022

Objectives

This double-blind, randomized clinical trial evaluated the influence of dentin moisture on postoperative sensitivity (POS), as well as, on clinical performance in posterior bulk-fill composite restorations, using a universal adhesive, until 12 months after clinical service.

Methods and Materials

In accordance with a split-mouth design, 45 patients received posterior restorations, restored with a bulk-fill resin composite (Filtek Bulk Fill, 3M Oral Care) and a universal adhesive used in etch-and-rinse mode (SBU; Single Bond Universal Adhesive), which were applied on dry or moist dentin, with a cavity depth of at least 3 mm. Three operators placed 90 Class I/Class II restorations. Patients were evaluated for spontaneous and stimulated POS in the baseline, and after 48 hours, 7 days, and at 6 and 12 months. In addition, secondary parameters (marginal discoloration, marginal adaptation, fracture, and recurrent caries) were evaluated by World Dental Federation (FDI) criteria after 7 days and at 6 and 12 months. Statistical analyzes were performed using the Chi-square, Fisher exact, Friedman, Kruskall–Wallis, and Mann–Whitney tests (α=0.05).

Results

No significant spontaneous and stimulated POS was observed when SBU was applied in dry and moist dentin (p>0.05). A significant and higher risk of spontaneous POS (20.0%; 95%CI 10.9–33.82 for dry dentin and 22.22%; 95%CI 12.54–36.27 for moist dentin) occurred up to 48 hours after restoration placement for the dry and moist dentin groups (p<0.02). However, the POS intensity was mild up to 48 hours with no significant difference between dry and moist dentin groups (p>0.79). When secondary parameters were evaluated, no significant differences between the groups were observed.

Conclusion

Dentin moisture did not influence POS in posterior bulk-fill composite restorations when associated with a universal adhesive applied in etch-and-rinse mode.
«Det lærte jeg egentlig ingen ting om da jeg studerte»: Ideologiske spenninger i høyere utøvende musikkutdanning
Authors: Vinge John , Røyseng Sigrid , Skrebergene Simen
Published: April 2022

This chapter outlines and discusses tensions within the ideological curriculum domain of higher music education; that is, various and often internally contested beliefs about what higher music education should teach, to what end, and for what reason. These tensions are brought to light by analysing qualitative interviews with 57 professional musicians representing a breadth of musical genres and practises. We have asked for the informants’ thoughts and reflection about their own education in light of their current working situation: In what way did they see that their own education prepared them for the professional life they were going into? What qualities do they attribute to their own education and what shortcomings are highlighted? The analysis highlights tensions between new and old teaching methods, between conservative traditions and more progressive endeavours, between art and business. These tensions are largely in line with prior music educational research that advocates for a revision of traditional music conservatory programs to meet the constant changes in the professional field of music.
Synlighet som karriereressurs for musikere
Authors: Røyseng Sigrid , Stavrum Heidi
Published: April 2022

This chapter investigates how musicians use, manage and value different types of visibility when building their careers. In order to analyze musicians’ experiences and opinions regarding visibility work, we apply three concepts of capital – symbolic capital, social capital and visibility capital. More specifically, we discuss how different forms of capital are valued by musicians in their endeavors to attain visibility. The analysis is based on empirical material from a study of professional musicians in Norway consisting of 57 qualitative interviews. The analysis is presented in four parts: visibility through social relations, visibility by presence in social media, visibility by presence in traditional media, and visibility by virtue of musicians’ geographical location. We find that both social capital – the visibility musicians get from networks and relations – and symbolic capital – the visibility musicians get from being recognized in the field – are seen as unconditionally valuable. However, visibility capital – the visibility musicians get from being present in social and traditional media – has a much more ambiguous status. One the one hand side, it is a way of connecting with and building audiences, which is seen as valuable. On the other hand, presence in social and traditional media requires a lot of work and is associated with certain subjective rules on how to appear and what to communicate.

Published: April 2022

In this paper the processes of admixture convective diffusion in two-phase structures with periodically located thin channels are investigated with taking into account a natural decay of migrating substance. With the help of application of appropriate integral transforms separately in the contacting domains, a solution of the contact initial boundary value problem of convective diffusion of decaying substance is obtained. The correlations between these integral transforms are found using the non-ideal contact conditions imposed for the concentration function. Expressions for decaying particle flows through arbitrary cross-section of the body are found and investigated, and their numerical analysis is carried out in the middle of both domains — the thin channel and basic material. It is shown that the decay intensity of the migrating substance especially affects the flow distribution in the domain of basic material.

Truancy as Predictor of Poor Academic Performance among Junior High School Students in Ashanti Mampong Municipality of Ghana
Authors: Ampofo Eric T. , Opoku Kingsley , Opoku-Manu Michael
Published: April 2022

One of the most serious disciplinary issues is student truancy. Researchers in this study want to know how truancy affects academic achievement among Junior High School pupils in Ghana's Ashanti Mampong Municipality. The data was collected using descriptive and correlational research methodologies, as well as a questionnaire. A multi-stage sampling procedure was used to determine the sample size of 331, which included 206 pupils and 25 teachers. Teachers' attitudes, corporal punishment/bullying, lack of parental supervision, broken households, peer influence, and poverty are the primary predictors of truancy among Junior High School pupils, according to the study's findings. There is also a positive association between school environment and truancy in this study. The outcomes of this study, once again, show a favorable link between parental socioeconomic position and truancy. In terms of the study's hypotheses, the researchers were unable to accept or deny the first and second hypotheses, respectively, based on the findings. Based on these findings, pupils should be taught about the dangers of being a truant. Parents should be encouraged to address their children's physical and emotional requirements. Parents should also keep an eye on their children to ensure that they complete their homework and attend school on a regular basis. Again, education groups and the government should work together to ensure that every child of school age attend school.
The Cultural Representations in the Unlock English Series and EFL Teachers’ and EFL Learners’ Perspectives towards Them
Authors: Abu Hussein Haya F.
Published: April 2022

This study aims to find out (1) to what extent the Unlock English textbooks present Big ‘C’ cultural themes, (2) to what extent the Unlock English textbooks present small ‘c’ cultural themes, and (3) what are EFL teachers’ and EFL learners’ perspectives towards the cultural content of the Unlock series. This research has adopted a mixed research design, both quantitative and qualitative. To answer the first two research questions, the cultural content of the Unlock textbooks was analyzed quantitively to find out all cultural themes included in the Unlock series. As for the third research question, a qualitative descriptive design was adopted by conducting the perspectives of (9) EFL teachers’ and (75) EFL learners’. The findings show that there is a wide range of various cultural themes available in the Unlock series, but with different frequencies and dominance. The findings also show teachers’ and learners’ attitudes towards the cultural content which appear to be generally positive. The researcher recommends enriching the EFL textbooks with more interesting and preferred cultural content.

Authors: Vamvuka D. , Chatzifotiadis I.
Published: April 2022

Different biomass waste materials were gasified by steam up to 850 °C, employing a fixed bed reactor and a thermal analysis-mass spectrometer unit. Raw fuels and biochars were characterized, while bio-oil, pyrolysis gas and syngas were quantitatively analyzed. Gasification efficiency and energy potential of all solid, liquid and gaseous products were determined. The higher heating value of biochar particles, bio-oil and pyrolysis gas ranged between 16-28 MJ/kg, 21.4-33.4 MJ/kg and 10.2-13.5 MJ/m3, respectively. Organic matter was almost completely converted to syngas and lower quantities of CO2, CH4 and hydrocarbons upon steam gasification, with H2 yield reaching values up to 60%. The higher heating value of syngas produced varied between 9.8 MJ/m3and 11.4 MJ/m3.

Published: April 2022

Aim: The aim of the study was to assess the effects of statins and fibrates on the lipid profile of patients with diabetes and to determine their side effects.
Methods: It was a transversal study. We included patients with type 1 or 2 diabetes that are followed in an outpatient department, treated for at least 3 months by statins or fibrates.We performed an interrogatory, a medical examination, dietary survey and biological tests for all patients.
Results:The mean age was 59.5 ± 9.2 years. Women were 65% of patients. The mean duration of treatment with statins and fibrates was 2.2 ± 2.6 years and 4.9 ± 4.2 years, respectively.Under statin therapy, total cholesterol and LDL cholesterol decreased significantly by 1.02±1.25 mmol/l and 0.32±0.47 mmol/l, respectively, triglycerides and HDL cholesterol decreased insignificantly.Fibrates caused a significant decrease in total cholesterol and triglycerides by 1.15± 2.24 mmol/l and 1.73 ±2.96 mmol/l, respectively and a non-significant decrease in LDL cholesterol and a non-significant increase in HDL cholesterol. No case of significant hepatic cytolysis was noted. Muscle pain was reported by 10.4% and 11.6% of patients on statins and fibrate, respectively.Under statins, the incidence of gastrointestinal symptoms increased significantly.
Conclusion: The efficacy of lipid lowering drugs is widely proven. Although side effects are possible, the prescription of lipid lowering drugs should be largely encouraged for better health care of patients with diabetes.
Phase Field Modeling of Ghost Diffusion in Sn-Ag-Cu Solder Joints
Authors: Weerasekera Naveen , Cao Siyua , Shingdon Dawa Ram
Published: April 2022

In this paper, we have introduced a phase field modeling technique to simulate ghost diffusion phenomena of intermetallic compounds in a bulk mettalic matrix phase. We  used Zenner-Frank phase field approach to define free energy density functional which is to be evolved using Chan-Hilliard and Alan-Chan equations to simulate time evolution of the precipitates. We verified our simulation results with intermetallic compound growth of Sn-Ag-Cu solder joints in isothermal aging process attributing to the diffusion of Ag3Sn intermetallic compound. Herewith we present that Zenner-Frank model demonstrates sound validity and provides a best understanding of such phenomena.
A Prospective Study Assessing Patient Perception of the Use Of Artificial Intelligence in Radiology
Authors: Clements Warren , Thong Louisa , Zia Adil , Moriarty Heather , Goh Gerard
Published: April 2022

Objective: Radiology has been at the forefront of medical technology including the use of artificial intelligence (AI) and machine learning. However, there remains scant literature on the perspective of patients regarding clinical use of this technology. This study aimed to assess the opinion of radiology patients on the potential involvement of AI in their medical care.
Design: A survey was given to ambulatory outpatients attending our hospital for medical imaging. The survey consisted of questions concerning comfort with radiologist reports, comfort with entirely AI reports, comfort with in-part AI reports, accuracy, data security, and medicolegal risk.
Setting: Tertiary academic hospital in Melbourne, Australia.
Main outcome measures: Patients’ were surveyed for their overall comfort with the use of AI in their medical imaging using a Likert scale of 0 to 7.
Results: 283 patient surveys were included. Patients rated comfort in their imaging being reported by a radiologist at mean of 6.5 out of 7, compared with AI alone at mean 3.5 out of 7 (p<0.0001), or in-part AI at mean 5.4 out of 7 (p<0.0001). Patients felt AI should have an accuracy of mean 91.4% to be able to be used in a clinical environment. Patients rated their current comfort with data security at mean 5.5 out of 7 however comfort with data security using AI at mean 4.4 out of 7, p<0.0001.
Conclusions: Patients are trusting of the holistic role of a radiologist however, remain uncomfortable with clinical use of AI as a standalone product including accuracy and data security. If AI technology is to evolve then it must do so with appropriate involvement of stakeholders, of which patients are paramount.
