Authors: Niu Zhaomeng , Wang Tingting , Hu Pengwei , Mei Jing , Tang Zhihan
Published: August 2020

BACKGROUND

Since January 2020, the coronavirus disease (COVID-19) swept over China and then the world, causing a global public health crisis. People’s adoption of preventive and intervening behaviors is critical in curbing the spread of the virus.

OBJECTIVE

The aim of this study is to evaluate Chinese people’s adoption of health behaviors in responding to COVID-19 and to identify key determinants for their engagement.

METHODS

An anonymous online questionnaire was distributed in early February 2020 among Mainland Chinese (18 years or older) to examine their engagement in preventive behaviors (eg, frequent handwashing, wearing masks, staying at home) and intervening behaviors (eg, advising family to wash hands frequently), and to explore potential determinants for their adoption of these health behaviors.

RESULTS

Out of 2949 participants, 55.3% (n=1629) reported frequent engagement in preventive health behaviors, and over 84% (n=2493) performed at least one intervening health behavior. Greater engagement in preventive behaviors was found among participants who received higher education, were married, reported fewer barriers and greater benefits of engagement, reported greater self-efficacy and emotional support, had greater patient-centered communication before, had a greater media literacy level, and had greater new media and traditional media use for COVID-19 news. Greater engagement in intervening behaviors was observed among participants who were married, had lower income, reported greater benefits of health behaviors, had greater patient-centered communication before, had a lower media literacy level, and had a greater new media and traditional media use for COVID-19 news.

CONCLUSIONS

Participants’ engagement in coronavirus-related preventive and intervening behaviors was overall high, and the associations varied across demographic and psychosocial variables. Hence, customized health interventions that address the determinants for health behaviors are needed to improve people’s adherence to coronavirus-related behavior guidelines.

Published: August 2020

BACKGROUND

Smartphone and wearable devices are widely used in behavioral and clinical research to collect longitudinal data that, along with ground truth data, are used to create models of human behavior. Mobile sensing researchers often program analysis code from scratch even though many research teams collect data from similar mobile sensors, platforms and devices. As a result, the quality of code varies, code is often not shared alongside publications, and when it is, it might not be stored on a version control system and most of the time there is no guarantee the development environment can be replicated. This makes it difficult for other scientists to read, reuse, audit, and reproduce a publication’s code and its results.

OBJECTIVE

We present RAPIDS, a reproducible pipeline to standardize the preprocessing, feature extraction, analysis, visualization, and reporting of data streams coming from mobile sensors.

METHODS

RAPIDS is formed by a group of R and Python scripts that are executed on top of reproducible virtual environments, orchestrated by Snakemake and organized following the cookiecutter data science project. Its development has been and will be informed by public discussions with the mobile sensing research community.

RESULTS

We share open source, documented, extensible and tested code to preprocess and extract behavioral features from data collected with the AWARE Framework in Android and iOS smartphones as well as Fitbit devices. We also provide a file structure and development environment that other researchers can follow to publish their own models, visualizations, and reports.

CONCLUSIONS

RAPIDS allows researchers to process mobile sensor data in a rigorous and reproducible way. This saves time and effort during the data analysis phase of a project and makes it easier to share an analysis workflow alongside publications.
Voluntary and involuntary attention in bistable visual perception: A MEG study (Preprint)
Authors: Chholak Parth , Maksimenko Vladimir A. , Hramov Alexander E. , Pisarchik Alexander N.
Published: August 2020

UNSTRUCTURED

Voluntary and involuntary visual attention in different interpretations of a bistable image was investigated using magnetoencephalography (MEG). A Necker cube with sinusoidally modulated pixels' intensity in the front and rear faces with frequencies 6.67 Hz (60/9) and 8.57 Hz (60/7), respectively, was presented to twelve healthy volunteers, who interpreted the cube as left- or right-oriented. The tags of these frequencies and their second harmonics were identified in the average Fourier spectra of the MEG data recorded from the visual cortex. In the first part of the experiment, the subjects were asked to voluntary focus their attention on interpreting the cube as either left- or right-orientated. Accordingly, we observed the dominance of the corresponding spectral component and voluntary attention performance was measured. In the second part of the experiment, the subjects were asked to focus their gaze on the red marker at the centre of the cube image without putting any effort in its interpretation. The alternation of the dominant spectral energies at the second harmonics of the tag frequencies was treated as changes in the cube orientation. Based on the results of the first experimental stage and using wavelet analysis, we developed a method which allowed us to identify the currently perceived cube orientations. Finally, we characterized involuntary attention using the dominance time distribution related to voluntary attention performance and brain noise. In particular, our hypothesis that higher attention performance is associated with stronger brain noise was confirmed.
The Effect of Information and Communication Technology and Social Networking Site Use on Older People’s Well-Being in Relation to Loneliness: Review of Experimental Studies (Preprint)
Authors: Casanova Georgia , Zaccaria Daniele , Rolandi Elena , Guaita Antonio
Published: August 2020

BACKGROUND

In the last decades, the relationship between social networking sites (SNSs) and older people’s loneliness is gaining specific relevance. Studies in this field are often based on qualitative methods to study in-depth self-perceived issues, including loneliness and well-being, or quantitative surveys to report the links between information and communication technologies (ICTs) and older people’s well-being or loneliness. However, these nonexperimental methods are unable to deeply analyze the causal relationship. Moreover, the research on older people’s SNS use is still scant, especially regarding its impact on health and well-being. In recent years, the existing review studies have separately focused their attention on loneliness and social isolation of older people or on the use of ICTs and SNSs in elderly populations without addressing the relationship between the former and the latter. This thorough qualitative review provides an analysis of research performed using an experimental or quasi-experimental design that investigates the causal effect of ICT and SNS use on elderly people’s well-being related to loneliness.

OBJECTIVE

The aims of this review are to contrast and compare research designs (sampling and recruitment, evaluation tools, interventions) and the findings of these studies and highlight their limitations.

METHODS

Using an approach that integrates the methodological framework for scoping studies and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for systematic reviews, we identified 11 articles that met our inclusion criteria. A thematic and content analysis was performed based on the ex post categorization of the data on the selected studies, and the data were summarized in tables.

RESULTS

The analysis of the selected articles showed that: (1) ICT use is positively but weakly related to the different measures of older people’s well-being and loneliness, (2) overall, the studies under review lack a sound experimental design, (3) the main limitations of these studies lie in the lack of rigor in the sampling method and in the recruitment strategy.

CONCLUSIONS

The analysis of the reviewed studies confirms the existence of a beneficial effect of ICT use on the well-being of older people in terms of reduced loneliness. However, the causal relationship is often found to be weak. This review highlights the need to study these issues further with adequate methodological rigor.

Authors: Chen Ying , Zhou Rui , Chen Boyan , Chen Hao , Li Ying , Chen Zhi , Zhu Haihong , Wang Hongmei
Published: August 2020

BACKGROUND

The COVID-19 pandemic continues to pose an international public health threat. Prevention is of paramount importance to protect the high-risk group of older adults until specific treatments for COVID-19 become available; however, little work has been done to explore factors that promote preventive behaviors among this population.

OBJECTIVE

This study aims to investigate the knowledge, perceived beliefs, and preventive behaviors towards COVID-19 of older adults in China and determine the factors that influence their practice of preventive behaviors.

METHODS

From February 19 to March 19, 2020, a cross-sectional, web-based survey was administered to Chinese older adults in all 31 provinces of mainland China using a convenience sampling method to assess the respondents’ knowledge, perceived beliefs, and preventive behaviors towards COVID-19. Standard descriptive statistics and hierarchical linear regression analyses were conducted to analyze the data.

RESULTS

A total of 1501 participants responded to the survey, and 1263 valid responses (84.1%) were obtained for further analysis. The overall correct rate on the knowledge questionnaire was 87%, overall positive beliefs regarding COVID-19 were found, and the mean behavior score was 13.73/15 (SD 1.62, range 5-15). The hierarchical linear regression showed that respondents who were married or cohabitating and who lived in areas with community-level control measures were more likely to practice preventive behaviors (P<.01). Knowledge (β=0.198, P<.001), perceived susceptibility (β=0.263, P=.03), perceived benefits (β=0.643, P<.001), and self-efficacy in preventing COVID-19 (β=0.468, P<.001) were also found to be significantly associated with preventive behaviors.

CONCLUSIONS

Most older residents had adequate knowledge and positive beliefs regarding COVID-19 and engaged in proactive behaviors to prevent the disease. Knowledge and beliefs were confirmed to be significantly associated with behavior responses. Our findings have significant implications in enhancing the effectiveness of COVID-19 prevention programs targeting the older population; these programs must be continued and strengthened as the epidemic continues.

Authors: FAYANKINNU Emmanuel Abiodun , AKINDE Sunday Israel
Published: August 2020

Previous research on banking sector reforms have investigated economic-related issues such as stability, operational effectiveness, and recapitalization among others, with little attention devoted to issues associated with employees’ perception of banks’ Merger and Acquisition (M&A) and the insecurity of jobs. This study examines employees’ perception of M&A reform in relation to their feelings about job insecurity. The systematic sampling technique is utilized to select eight hundred and fifty-six employees from purposively selected commercial banks on who structured scales, measuring perceived job insecurity and M&A (reforms) outcomes were administered. Data are analysed descriptively and Pearson Correlation used to test the formulated hypothesis. Findings from the study show that employees reported mixed perceptions about the items on the scale. M&A engendered improved efficiency, training and leadership capability on the one hand, while it increased employees’ workload and working hours without a corresponding income value; and, alienate employees from leisure. The test of hypothesis indicates an inverse correlation between employees’ perception of M&A and employees feeling of job insecurity. The implications from the findings are discussed for theory and practice.

Published: August 2020

Las iniciativas para mejorar la competitividad sectorial son recurrentes en América Latina, canalizadas a menudo en estrategias formales e informales tipificadas como clústeres en sus distintas acepciones. En este contexto, la evaluación del impacto sobre la competitividad de las empresas y el desarrollo territorial se torna necesaria. En Argentina, las experiencias son variadas, en general con poca información sobre el impacto real. El objetivo del artículo es ofrecer una evaluación exploratoria del impacto de un incipiente clúster de frutos secos en una región cuya actividad tradicional se encuentra en crisis. La metodología es de carácter retrospectivo siguiendo los lineamientos que propusieron Gertler, Martínez, Premand, Rawlings y Vermeersch en 2011. Tras la discusión sobre el escenario contrafactual, se detallan la evolución histórica del clúster, sus objetivos, los proyectos, la cadena de valor del sector y se evalúan sus impactos. Las principales conclusiones son que el acceso, el caudal y la calidad de la información que ha circulado dentro del clúster han tenido efectos significativos y positivos en el desempeño. Los impactos en el territorio resultan positivos, aunque el tiempo trascurrido para la evaluación es aún breve. La principal dificultad del clúster se encuentra en la escasez de financiamiento, lo cual limita sus posibilidades de crecimiento.

Background: In last few years .; it’s  increasingly being recognized  that  Reproductive function is controlled by the hypothalamic–pituitary– gonadal axis, which is regulated by numerous endogenous and environmental factors  such us adipose accumulation in obesity  contributing to reproductive failure  such as menstrual disorders and infertility, gestational failure and obstetric complications, and infertility , Distinct changes in circulating sex hormones appear to underline these abnormalities.

The objective: The aim of this study was to elucidate the possible correlation between body mass index as fatness indicator and hormonal profile in infertile women from the west of Algeria.

To identify the impact of overweight  and obesity on female hormonal profile ; we  conducted a prospective study  measuring pituitary hormones  (FSH  and LH and prolactin ) , steroid sex hormones ( progesterone , testosterone and estradiol ) , anti miulleian hormone , and thyroidal hormones (FT3 , FT4 and TSH) in 360 women  consulting for subfertility in private genecologycal and obstetrical centers in SID BELABESS (West of Algeria )

Result: Our study showed that the majority of patients were aged between 20 and 29 years, representing a percentage of 47.8%, with the average age in sample (31.65 ± 6,93ans). The majority of subjects was obese   46.4%, or overweight (39.4%) with an average BMI of (29.76 ± 4,85Kg / m2). No statistically significant association was found between the BMI as obesity indicator with hormonal levels of pituitary hormones  (FSH  and LH and prolactin ) , steroid sex hormones ( progesterone , testosterone and estradiol ) , anti miulleian hormone , and thyroidal hormones (FT3 , FT4 and TSH). A negative and statistically significant correlation between the age of the patients and the AMH level (R = -0.60, P <0.01) was noted.

Conclusion: The results of our study showed that the majority of women included in our study had a high BMI but no statistical significant difference was found between underweight , normal , overweight and obese women , that’s why more studies should be conducted to elucidate the in which level does obesity impair the reproductive outcomes.

Published: August 2020

Introduction: Tricho-dento-osseous syndrome is a ultra-rare ectodermal dysplasia related to genetic alterations in the DLX3 gene of interest to the health sciences due to its clinical manifestations. Aim: To synthesize the scientific evidence about tricho-dento-osseous syndrome, especially for dentistry. Methods: A bibliographic search was performed in the MEDLINE / PubMed, Web of Science and Scopus databases. A search strategy with descriptors was applied to all databases mentioned to reach scientific articles. The articles reached in all databases had their titles and abstracts read in search of adaptation to the proposed objective. There was no restriction on the year of publication, country or language. Literature review: Patients diagnosed with this syndrome have dental enamel defects and severe taurodontism, especially in the permanently lower first molars. In addition to these signs, other manifestations may be associated, such as curly hair, increased bone density and changes in craniofacial bones. The diagnosis of tricho-dento-osseous syndrome can be challenging due to the heterogeneity and wide phenotypic variation presented by patients with DLX3 mutations, since this gene is associated with several functions, especially related to cell differentiation and biomineralization. In addition, it is necessary to consider that other dental anomalies may be confused with tricho-dento-osseous syndrome, especially cases of imperfect amelogenesis associated with taurodontism. Conclusion: For dentistry, oral manifestations caused by this syndrome become relevant for diagnostic and therapeutic purposes, although there are no clinical protocols for dental management of this patients.

Published: August 2020

Frente à necessidade de reintervenção em restaurações insatisfatórias, os clínicos podem, em geral, optar pela substituição ou reparo. Este artigo relata um caso clínico de reparo de uma restauração de resina composta com falha em dente decíduo. Após profilaxia e isolamento relativo, a porção da resina composta a ser reparada foi asperizada com uma ponta diamantada em alta rotação com o intuito de melhorar a união mecânica entre a resina envelhecida e a nova (reparo). Foi realizado o condicionamento com gel de ácido fosfórico a 34% por 15 segundos, seguido de lavagem e secagem. Uma camada do sistema adesivo Single Bond Universal (3M ESPE) foi aplicada ativamente durante 20 segundos, seguido de jato de ar comprimido por 5 segundos e fotoativação por 10 segundos. Por fim, a resina composta fluida (Filtek Z350 XT Flow; 3M ESPE) foi inserida e fotoativada por 20 segundos. A realização de um adequado protocolo clínico envolvendo tratamentos físicos e químicos de superfície é fundamental para a efetividade da intervenção e a manutenção do dente decíduo clinicamente funcional até a esfoliação fisiológica.

Published: August 2020

O hemangioma é uma lesão vascular, podendo representar-se como uma neoplasia benigna dos vasos sanguíneos, relativamente rara na cavidade oral, podendo causar prejuízo estético e funcional a depender da sua região. Sua localização mais frequente é o lábio superior, mas pode ocorrer em outras regiões, como língua, mucosa jugal e palato. O seu tratamento depende, principalmente, do correto diagnóstico da lesão, bem como da localização anatômica da mesma e pode ser realizado com esclerose química, crioterapia, laserterapia, excisão cirúrgica convencional, embolia arterial ou eletrocautério. O objetivo desse trabalho é apresentar um caso clínico, de um paciente do gênero masculino, 63 anos de idade, apresentando hemangioma desde os 16 anos de idade, com recidiva há dez anos em lábio superior. Ao exame físico intrabucal observou-se uma lesão tumoral, de coloração arroxeada, base séssil, assintomática, com limites bem definidos, medindo aproximadamente 4 cm em seu maior diâmetro, localizada na mucosa labial superior. Foi realizada manobra de vitropressão que apresentou um esmaecimento da coloração arroxeada, permitindo diagnóstico clínico de hemangioma. O tratamento proposto foi a esclerose terapêutica com cinco aplicações de oleato de monoetanolamina 5%, considerando as características clínicas e os métodos de diagnóstico desta lesão. Por meio de um diagnóstico preciso e uma conduta terapêutica adequada, o caso apresenta-se com um acompanhamento de dois meses com significativa redução até o momento, e com um resultado estético funcional satisfatório. Conclui-se que a eficácia da escleroterapia realizada com o uso do oleato de monoetanolamina 5% é uma alternativa terapêutica segura.

Durante o atendimento odontológico, o paciente pode ser exposto a várias fontes de contaminações, por isso a equipe odontológica deve sempre implementar ações de biossegurança. Materiais não autoclaváveis, como os tubetes anestésicos, necessitam ser desinfetados previamente ao seu uso, pois não são estéreis, podendo transmitir patógenos entre os pacientes. Este estudo objetivou avaliar e comparar a eficácia de três soluções desinfetantes na redução da carga microbiana em tubetes de anestésicos odontológicos. Os tubetes anestésicos (n=31) foram escolhidos aleatoriamente e submetidos a diferentes métodos e agentes desinfetantes (Álcool 70%, Dióxido de Cloro 7%; Cloreto de benzalcônio 5,2% com Polihexametileno biguanida 3,5%). Após a desinfecção por métodos de imersão ou fricção, os tubetes foram semeados em meio de cultura contendo caldo tripticase de soja e incubados (48h/370C). Amostras do meio de cultura líquido foram repicadas e semeadas em ágar tripticase de soja, incubado durante 48h a 370C. O crescimento microbiano foi observado pela presença de unidades formadoras de colônias (UFCs) crescidas no ágar. O estudo concluiu que os produtos Álcool 70% e Cloreto de benzalcônio 5,2% com Polihexametileno biguanida 3,5% demostraram ser mais eficazes na eliminação da carga microbiana dos tubetes pelo método de fricção, e que realmente os tubetes anestésicos tem sua superfície externa contaminada. O estudo comprovou ser o método de fricção do agente desinfetante mais eficaz na redução da carga microbiana comparado a imersão. Dos agentes testados, o Dióxido de Cloro 7% não demonstrou um nível de desinfecção satisfatório.

Published: August 2020

Introduction: In studies on the prevalence of tooth wear, few publications related to young adults are found. Objectives: To explore the associations of behavioral, medical, and socio-demographic variables with prevalence and severity of tooth wear of the whole dentition, in a sample of young adults, using a modified version of the Tooth Wear Index (TWI). Methods: Sample consisted of 116 university dental students with an average age of 23 years, who answered a questionnaire related to sociodemographic variables, self-perception and health behaviors. In addition, individuals underwent a clinical evaluation of tooth wear by one trained examiner using the TWI modified by Smith and Knight. Logistic regression was carried out at individual level. Results: A total of 9,906 dental surfaces in 116 individuals were examined, 72.27 % dental surfaces had no tooth wear (grade 0), but all individuals had at least one worn surface. Among the individuals, 78,4 % had grade 1 (enamel) as the highest level and 21.6% grade 2 (dentin) as the highest level. The presence of grade 2 tooth wear was mainly prevalent in the following individuals: male; smoker; with bruxism, and among those who reported having undergone orthodontic treatment. Analyzing the relevant factors that affect tooth wear by multiple regression analysis, it was found that smoking (OR 6.67; IC 1.73- 25.76) and bruxism (grinding) (OR 4.05; IC 1.29- 12.7) had the greatest effect on tooth wear. Conclusions: Our results suggest that being male, being a current smoker, having grinding bruxism and having previous orthodontic treatment are associated with tooth wear.

A Odontologia Hospitalar visa à manutenção e aos cuidados prestados a pacientes sob internação hospitalar. O cirurgião-dentista é um profissional devidamente capacitado para identificação, prevenção e tratamento de alterações na cavidade bucal. A inserção do CD em ambiente hospitalar tem sido instituída mediante resoluções e leis para beneficiar quem carece desse atendimento. Sendo assim, o objetivo deste trabalho é apresentar trajetória da Odontologia Hospitalar no Brasil, verificar seu panorama atual e mostrar sobre a importância desse profissional na equipe multidisciplinar dos hospitais. As buscas foram realizadas, entre os anos de 2001 e 2019, em bases de dados bibliográficos nacionais e como complemento no manual de odontologia hospitalar, em matérias publicadas pela Agência Nacional de Vigilância Sanitária e em leis publicadas nos diários oficiais dos municípios, estados e união. Os dados mostram que muitos estados já se adequaram, do ponto de vista legal, no sentido de tornar a Odontologia Hospitalar uma realidade. No entanto, ainda falta fiscalização e profissionais ocupando todos os postos de trabalho. Logo, percebe-se que a última década foi decisiva em prol da Odontologia Hospitalar, mas ainda há muito o que se fazer para que novos avanços aconteçam.

Published: August 2020

Introdução: A síndrome do cromossomo X frágil é uma síndrome genética que acomete principalmente indivíduos do sexo masculino. O nome desta síndrome ocorre como consequência de um estreitamento da extremidade distal do braço longo do cromossomo X, local chamado de sítio frágil. O presente trabalho apresenta uma revisão de literatura, apresentando etiologia, prevalência, métodos de diagnóstico, características comportamentais, características físicas gerais e de interesse odontológico, além das considerações acerca do atendimento, realizado pelo cirurgião-dentista, em portadores da síndrome do X frágil. Revisão de literatura: As principais características comportamentais são o déficit de atenção, a dificuldade na interação social, a timidez, a ansiedade, a labilidade emocional e os movimentos estereotipados de mãos. Os achados de interesse odontológico mais prevalentes na literatura foram palato ogival, prognatismo mandibular, macroglossia, hipoplasia de esmalte e má oclusão. Discussão: Não foram encontrados muitos artigos voltados para a análise facial e odontológica destes pacientes. O atendimento deste público é um desafio para o cirurgião-dentista devido às características comportamentais e fisiológicas apresentadas. Conclusão: o conhecimento das características desta síndrome pelo profissional é importante, pois a síndrome comumente se associa à doenças sistêmicas que podem influenciar no plano de tratamento, além de alterações orofaciais importantes.
Treatment of black copper with the use of iron scrap - part I

Currently, there is a large amount of mineral resources not being exploited in large copper minings, a clear example are black copper minerals. These resources are generally not incorpo-rated into the extraction circuits or are not treated, either in stocks, leach pads, or debris. These exotic minerals have considerable amounts of Cu and Mn, which are commercially very attractive. They are refractory to conventional leaching processes, therefore, the use of reducing agents is necessary for treatment of these minerals in order to dissolve the present MnO2, which in turn allows Cu extraction. In this research, iron scrap Fe0 was used as a reducing agent for the dissolution of Mn from a black copper mineral in an acidic medium and compared to previous studies of the use of Fe2+ under the same conditions. In addition, the effects of a pretreatment process (agglomeration and curing) by adding NaCl are investigated in order to favor the reduction of MnO2. Finally, it was discovered that there is a higher kinetics of dissolution of Mn when working with Fe0 in short periods of time, although similar extraction efficiencies are obtained after prolonged times. The pretreatment process by adding NaCl resulted in increased Mn extraction in short periods of time (30 min). At applying high concentrations of the reducing agent, the effect of particle size on the dissolution rate of MnO2 was shown to be insignificant.

Zinc oxide (ZnO) nanoparticles were obtained by thermal decomposition of one-dimensional zinc?benzenepolycarboxylato complexes as single- -source precursors at 450 ?C in an air atmosphere. The mechanism and kinetics of thermal degradation of zinc?benzenepolycarboxylato complexes were analyzed under non-isothermal conditions in an air atmosphere. The results of X-ray powder diffraction and field emission scanning electron microscopy revealed hexagonal wurtzite structure of ZnO with an average crystallite size in the range of 39?47 nm and similar morphology. The band gap and the specific surface area of ZnO nanoparticles were determined using UV?Vis diffuse reflectance spectroscopy and the Brunauer, Emmett and Teller method, respectively. The photoluminescent, photocatalytic and antimicrobial properties of the ZnO nanoparticles were also examined. The best photocatalytic activity in the degradation of C. I. Reactive Orange 16 dye was observed for the ZnO powder where the crystallites form the smallest agglomerates. All ZnO nanoparticles showed excellent inhibitory effect against Gram-positive bacterium Staphylococcus aureus and Gram-negative bacterium Escherichia coli.
Continuous Auditing and Risk-Based Audit Planning—An Empirical Analysis
Authors: Eulerich Marc , Georgi Christine , Schmidt Alexander
Published: August 2020

Due to rapidly changing risks in companies, a continuous alignment of internal audit activities with the relevant risks is required. Continuous auditing (CA) is one possible way to meet these requirements. Specifically, the internal audit function (IAF) could use CA as a methodology in order to add a continuous perspective to their risk assessment. This study examines factors associated with the use of CA information in the IAF's risk-based audit planning (RBAP). We use survey data from 264 chief audit executives to address our research question. We find several factors having a positive influence on the use of information from CA in RBAP. These factors include the importance of data analytics, the collaboration with the audit committee and external auditor, as well as the use of IAF's results for fraud prevention. Furthermore, our additional analysis presents various positive effects of CA on potential output measures of internal auditing.
