Published: May 2024

This study covers the purification and sterilization stations in different regions of the Iraqi city of Baghdad. To systematically conduct this study, several drinking water samples were collected from various sites in Al-Karkh and Al-Rusafa in Baghdad. These samples were tested bacteriologically, such as Bacterial Total Count, Total Coliform Bacteria, fecal bacteria, and Escherichia coli (E. coli). Furthermore, the physical properties of the total hardness (TH), turbidity, residual chlorine, and pH from June 2021 to July 2022 were measured monthly. The seasonal variation of the research parameters is considered by providing a statistical description. The biological tests indicate that the water is seriously contaminated with fecal coliform in one area of the Al-Karkh region during the months of autumn and summer. Also, the biological tests of the Al-Rusafa region elucidate the dangerous concentrations of plate count bacteria in summer and autumn. Furthermore, the Al-Rusafa region reports cases of E. coli and coliform in the summer, which exceed the Iraqi and WHO guidelines. But, the physical tests ascertain the semi-alkalinity of drinking water with the greatest residual chlorine value of 0.9 ppm in the summer.

Inhibitory Activity of Quercetin, Rutin, and Hyperoside against Xanthine Oxidase: Kinetics, Fluorescence, and Molecular Docking
Authors: Yu Yali , Xiong Yingzhu , Tong Siman , Li Yanli , Cai Rongcan , Zhang Xv , Gao Feng
Published: May 2024

Introduction:

Quercetin (Qc), rutin (Ru), and hyperoside (Hyp) are three common
polyphenols widely distributed in the plant kingdom.

Methods:

This study explored the inhibition and mechanisms of Qc, Ru, and Hyp against xanthine
oxidase (XOD) by enzyme kinetic analysis, fluorescence analysis, and molecular docking.
The inhibitory activities of the three polyphenols on XOD showed the following trend: quercetin
> hyperoside > rutin, with IC50 values of 8.327 ± 0.36 μmol/L, 35.215 ± 0.4 μmol/L and
60.811 ± 0.19 μmol/L, respectively. All three polyphenols inhibited xanthine oxidase activity in
a mixed-competitive manner. Synchronous fluorescence results demonstrated that three polyphenols
binding to XOD were spontaneous and showed static quenching.

Results:

The binding of the three polyphenols to XOD is mainly driven by hydrogen bonding
and van der Waals forces, resulting in the formation of an XOD-XA complex with only one affinity
binding site. The binding sites of the three RSFQ phenolic compounds are close to those of
tryptophan. Molecular docking showed that all three polyphenols enter the active pocket of XOD
and maintain the stability of the complex through hydrogen bonding, hydrophobic interaction,
and van der Waals forces.

Conclusion:

The results provide a theoretical basis for quercetin, rutin, and hyperoside to be
used as function factors to prevent hyperuricemia.
Expression of LASS2 Can be Regulated by Dihydroartemisinin to Regulate Cisplatin Chemosensitivity in Bladder Cancer Cells
Authors: Qiao Xuhua , Xue Rongbo , Li Shijie , Li Jun , Ji Chundong
Published: May 2024

Introduction:

The aim of this study was to investigate the potential of dihydroartemisinin
to augment the efficacy of cisplatin chemotherapy through the modulation of LASS2
expression.

Methods:

TCMSP, CTR-DB, TCGA-BLC, and other databases were used to analyze the possibility
of LASS2 as the target gene of dihydroartemisinin. Cell experiments revealed the synergistic
effect of DDP and DHA. Animal experiments showed that DHA inhibited the growth of
DDP-treated mice. In addition, WB, real-time PCR, and immunohistochemical analysis showed
that DHA enhanced LASS2 (CERS2) expression in bladder cancer cells and DDP-treated mice.

Results:

LASS2 is associated with cisplatin chemosensitivity.LASS2 expression levels are different
between BLC tissues and normal tissues. COX analysis showed that patients with high
LASS2 expression had a higher cumulative overall survival rate than those with low LASS2
expression. The Sankey plot showed that LASS2 expression is lower in BLC tissues with more
advanced stage and distant metastasis. The docking score of DHA and LASS2 reached the maximum
value of -5.5259, indicating that DHA had a strong binding affinity with LASS2 targets.
CCK8 assay showed that the most effective concentration ratio of DHA to DDP was 2.5 μg/ml +
10μg/ml. In vivo experiments showed that DHA inhibited tumor growth in cisplatin-treated mice.
In addition, WB, RT-qPCR, and immunohistochemical analysis showed that DHA was able to
enhance LASS2 expression in BLC cells and DDP-treated mice.

Conclusion:

The upregulation of LASS2 (CERS2) expression in bladder cancer cells by DHA
has been found to enhance cisplatin chemosensitivity.
Rare Columnar Cell Variant of Papillary Thyroid Carcinoma with Cervical
Spine Metastasis: A Case Report
Authors: Yu Jihye , Yang Goeun , Oh Ha Yeun , Ryu Yoon Jong
Published: May 2024

Background::

Columnar cell carcinoma is a rare subtype of papillary thyroid carcinoma (CCV-PTC) that accounts for only 0.15% to 0.2% of all Papillary
Thyroid Carcinomas (PTCs). It has aggressive behavior but a better prognosis than anaplastic thyroid carcinoma.

Case Presentation::

A 64-year-old female presented with a huge thyroid mass resulting in compressive myelopathy and was diagnosed as CCV-PTC, not anaplastic
carcinoma. After multidisciplinary discussions, we decided to proceed with otolaryngological, thoracic, and orthopaedic surgery. All tumours were
unresectable, and we planned to proceed with R2 resection to resolve the gait disturbance and anterior fusion to resolve spinal instability.

Conclusion::

Advanced-stage thyroid cancer is relatively uncommon, but desirable treatment effects can be expected through accurate pathological diagnosis.
Immunohistochemical staining and tissue-specific markers can be helpful.
Fibrosarcomatous Transformation in Dermatofibrosarcoma Protuberans of the
Male Breast and its Association with Magnetic Resonance Imaging and
Immunohistopathologic Features
Authors: Kang Sang Yull , Choi Eun Jung , Jang Kyu Yun
Published: May 2024

Background:

Dermatofibrosarcoma Protuberans (DFSP) is a rare soft tissue sarcoma, accounting for approximately 1% of all tumors; however, DFSP of the
breast is extremely rare. Moreover, DFSP generally has a low malignant potential and is characterized by a high rate of local recurrence along with
a small but definite risk of metastasis. The risk of metastasis is higher in fibrosarcomatous transformation in DFSP than in ordinary DFSP.

Case Report:

We have, herein, reported a case of a 61-year-old male patient with fibrosarcomatous transformation in DFSP. Preoperative Dynamic Contrastenhanced
Magnetic Resonance Imaging (DCE-MRI) of the breast revealed an oval-shaped mass with heterogeneous internal enhancement, a large
vessel embedded within, and a washout curve pattern on kinetic curve analysis. The mass exhibited a hyperintense signal on Diffusion-weighted
Imaging (DWI), with a low apparent diffusion coefficient value. Histologically, the bland spindle tumor cells were arranged in a storiform pattern.
Areas with the highest histological grade demonstrated increased cellularity, cytological atypia, and mitotic activity. Immunohistochemically,
Ki-67 and p53 were highly expressed.

Conclusion:

Recognizing the risk and accurately diagnosing fibrosarcomatous transformation in male breast DFSP are critical for improving prognosis and
establishing appropriate treatment and follow-up plans. This emphasizes the significance of combining immunohistopathological features with
DCE-MRI and DWI to assist clinicians in the early and accurate diagnosis of sarcomas arising from male breast DFSP.
Insights From a Clinically Orientated Workshop on Health Care Cybersecurity and Medical Technology: Observational Study and Thematic Analysis
Authors: Straw Isabel , Brass Irina , Mkwashi Andrew , Charles Inika , Soares Amelie , Steer Caroline
Published: May 2024

Background

Health care professionals receive little training on the digital technologies that their patients rely on. Consequently, practitioners may face significant barriers when providing care to patients experiencing digitally mediated harms (eg, medical device failures and cybersecurity exploits). Here, we explore the impact of technological failures in clinical terms.

Objective

Our study explored the key challenges faced by frontline health care workers during digital events, identified gaps in clinical training and guidance, and proposes a set of recommendations for improving digital clinical practice.

Methods

A qualitative study involving a 1-day workshop of 52 participants, internationally attended, with multistakeholder participation. Participants engaged in table-top exercises and group discussions focused on medical scenarios complicated by technology (eg, malfunctioning ventilators and malicious hacks on health care apps). Extensive notes from 5 scribes were retrospectively analyzed and a thematic analysis was performed to extract and synthesize data.

Results

Clinicians reported novel forms of harm related to technology (eg, geofencing in domestic violence and errors related to interconnected fetal monitoring systems) and barriers impeding adverse event reporting (eg, time constraints and postmortem device disposal). Challenges to providing effective patient care included a lack of clinical suspicion of device failures, unfamiliarity with equipment, and an absence of digitally tailored clinical protocols. Participants agreed that cyberattacks should be classified as major incidents, with the repurposing of existing crisis resources. Treatment of patients was determined by the role technology played in clinical management, such that those reliant on potentially compromised laboratory or radiological facilities were prioritized.

Conclusions

Here, we have framed digital events through a clinical lens, described in terms of their end-point impact on the patient. In doing so, we have developed a series of recommendations for ensuring responses to digital events are tailored to clinical needs and center patient care.
Key Considerations for Designing Clinical Studies to Evaluate Digital Health Solutions
Authors: Bolinger Elaina , Tyl Benoit
Published: May 2024

Evidence of clinical impact is critical to unlock the potential of digital health solutions (DHSs), yet many solutions are failing to deliver positive clinical results. We argue in this viewpoint that this failure is linked to current approaches to DHS evaluation design, which neglect numerous key characteristics (KCs) requiring specific scientific and design considerations. We first delineate the KCs of DHSs: (1) they are implemented at health care system and patient levels; (2) they are “complex” interventions; (3) they can drive multiple clinical outcomes indirectly through a multitude of smaller clinical benefits; (4) their mechanism of action can vary between individuals and change over time based on patient needs; and (5) they develop through short, iterative cycles—optimally within a real-world use context. Following our objective to drive better alignment between clinical evaluation design and the unique traits of DHSs, we then provide methodological suggestions that better address these KCs, including tips on mechanism-of-action mapping, alternative randomization methods, control-arm adaptations, and novel end-point selection, as well as innovative methods utilizing real-world data and platform research.
The Impact of Behavior Change Counseling Delivered via a Digital Health Tool Versus Routine Care Among Adolescents With Obesity: Pilot Randomized Feasibility Study (Preprint)
Authors: Kepper Maura , Walsh-Bailey Callie , Miller Zoe M , Zhao Min , Zucker Kianna , Gacad Angeline , Herrick Cynthia , White Neil H , Brownson Ross C , Foraker Randi E
Published: May 2024

BACKGROUND

Youth overweight and obesity is a public health crisis and increases the risk of poor cardiovascular health (CVH) and chronic disease. Health care providers play a key role in weight management, yet few tools exist to support providers in delivering tailored evidence-based behavior change interventions to patients.

OBJECTIVE

The goal of this pilot randomized feasibility study was to determine the feasibility of implementing the Patient-Centered Real-Time Intervention (PREVENT) tool in clinical settings, generate implementation data to inform scale-up, and gather preliminary effectiveness data.

METHODS

A pilot randomized clinical trial was conducted to examine the feasibility, implementation, and preliminary impact of PREVENT on patient knowledge, motivation, behaviors, and CVH outcomes. The study took place in a multidisciplinary obesity management clinic at a children’s hospital within an academic medical center. A total of 36 patients aged 12 to 18 years were randomized to use PREVENT during their routine visit (n=18, 50%) or usual care control (n=18, 50%). PREVENT is a digital health tool designed for use by providers to engage patients in behavior change education and goal setting and provides resources to support change. Patient electronic health record and self-report behavior data were collected at baseline and 3 months after the intervention. Implementation data were collected via PREVENT, direct observation, surveys, and interviews. We conducted quantitative, qualitative, and mixed methods analyses to evaluate pretest-posttest patient changes and implementation data.

RESULTS

PREVENT was feasible, acceptable, easy to understand, and helpful to patients. Although not statistically significant, only PREVENT patients increased their motivation to change their behaviors as well as their knowledge of ways to improve heart health and of resources. Compared to the control group, PREVENT patients significantly improved their overall CVH and blood pressure (P<.05).

CONCLUSIONS

Digital tools can support the delivery of behavior change counseling in clinical settings to increase knowledge and motivate patients to change their behaviors. An appropriately powered trial is necessary to determine the impact of PREVENT on CVH behaviors and outcomes.

Authors: Kim Hyejun , Son Yejun , Lee Hojae , Kang Jiseung , Hammoodi Ahmed , Choi Yujin , Kim Hyeon Jin , Lee Hayeon , Fond Guillaume , Boyer Laurent , Kwon Rosie , Woo Selin , Yon Dong Keon
Published: May 2024

BACKGROUND

Suicide is the second-leading cause of death among adolescents and is associated with clusters of suicides. Despite numerous studies on this preventable cause of death, the focus has primarily been on single nations and traditional statistical methods.

OBJECTIVE

This study aims to develop a predictive model for adolescent suicidal thinking using multinational data sets and machine learning (ML).

METHODS

We used data from the Korea Youth Risk Behavior Web-based Survey with 566,875 adolescents aged between 13 and 18 years and conducted external validation using the Youth Risk Behavior Survey with 103,874 adolescents and Norway’s University National General Survey with 19,574 adolescents. Several tree-based ML models were developed, and feature importance and Shapley additive explanations values were analyzed to identify risk factors for adolescent suicidal thinking.

RESULTS

When trained on the Korea Youth Risk Behavior Web-based Survey data from South Korea with a 95% CI, the XGBoost model reported an area under the receiver operating characteristic (AUROC) curve of 90.06% (95% CI 89.97-90.16), displaying superior performance compared to other models. For external validation using the Youth Risk Behavior Survey data from the United States and the University National General Survey from Norway, the XGBoost model achieved AUROCs of 83.09% and 81.27%, respectively. Across all data sets, XGBoost consistently outperformed the other models with the highest AUROC score, and was selected as the optimal model. In terms of predictors of suicidal thinking, feelings of sadness and despair were the most influential, accounting for 57.4% of the impact, followed by stress status at 19.8%. This was followed by age (5.7%), household income (4%), academic achievement (3.4%), sex (2.1%), and others, which contributed less than 2% each.

CONCLUSIONS

This study used ML by integrating diverse data sets from 3 countries to address adolescent suicide. The findings highlight the important role of emotional health indicators in predicting suicidal thinking among adolescents. Specifically, sadness and despair were identified as the most significant predictors, followed by stressful conditions and age. These findings emphasize the critical need for early diagnosis and prevention of mental health issues during adolescence.
The Paradigm Shift From Patient to Health Consumer: 20 Years of Value Assessment in Health (Preprint)
Authors: van den Broek-Altenburg Eline M , Atherly Adam J
Published: May 2024

UNSTRUCTURED

Health care is undergoing a “revolution,” where patients are becoming consumers and armed with apps, consumer review scores, and, in some countries, high out-of-pocket costs. Although economic analyses and health technology assessment (HTA) have come a long way in their evaluation of the clinical, economic, ethical, legal, and societal perspectives that may be impacted by new technologies and procedures, these approaches do not reflect underlying patient preferences that may be important in the assessment of “value” in the current value-based health care transition. The major challenges that come with the transformation to a value-based health care system lead to questions such as “How are economic analyses, often the basis for policy and reimbursement decisions, going to switch from a societal to an individual perspective?” and “How do we then assess (economic) value, considering individual preference heterogeneity, as well as varying heuristics and decision rules?” These challenges, related to including the individual perspective in cost-effectiveness analysis (CEA), have been widely debated. Cost-effectiveness measures treatments in terms of costs and quality-adjusted life-years (QALYs), where QALYs assume that a health state that is more desirable is more valuable, and therefore, value is equated with preference or desirability. QALYs have long been criticized for empirical and conceptual shortcomings. However, policy makers in many countries have used QALY measures to make health coverage decisions, although now, patients, and patient advocates, are questioning the valuation methodologies. This has led to the development of new approaches to valuing health, which are already starting to be used in the United States. This paper reviews 20-25 years of value assessment approaches in health and concludes with challenges and opportunities for value assessment methods in health in the years to come.
Combating health misinformation through fact-checking - the role of active versus passive social media involvement (Preprint)
Authors: Zhou Xuan , Pan Wenjing , Jiang Shaohai
Published: May 2024

BACKGROUND

Health information fact-checking has been identified as a potential solution to combat the spread of misinformation on social media. Therefore, it is crucial to understand what factors are associated with individuals’ fact-checking behaviors on health (mis)information.

OBJECTIVE

The objective of this study is to examine how two types of social media involvement (active vs. passive) affect individuals’ fact-checking behaviors.

METHODS

A cross-sectional online survey was conducted in China to collect the data. The final sample consisted of 600 social media users. Descriptive statistics and correlational analyses were performed to explore the relationships between key variables.

RESULTS

The results indicated that passive and active social media involvement were negatively and positively associated with health information fact-checking, respectively. Further analysis revealed that the association between the two ways of social media involvement and health information fact-checking was mediated by social media fatigue and moderated by health information literacy.

CONCLUSIONS

Various ways in which people are involved with social media can bring different health information outcomes. Active involvement correlates with higher fact-checking possibility. Decreasing social media fatigue and enhancing health information literacy are crucial for countering the proliferation of misinformation.

Privacy Challenges and Solutions in Big Data Analytics: A Comprehensive Review
Authors: Ramakrishnan Mr. R.
Published: May 2024

Abstract: Large data collections with a more intricate and diversified structure are referred to as "big data." These traits are typically associated with more challenges when it comes to storing, analyzing, and applying additional procedures or getting results. The technique of analyzing vast quantities of intricate data to uncover patterns or connections that are concealed is known as "big data analytics." Nonetheless, there is a clear conflict between big data's extensive use and its security and privacy. This paper examines privacy needs in big data, distinguishes between privacy and security, and focuses on privacy and security issues in large data. This study addresses the applications of privacy in business by utilizing established techniques like HybrEx, k-anonymity, T-closeness, and L-diversity. Many privacy-preserving techniques have been created for protection of privacy at various phases of the big data life cycle (such as data generation, storage, and processing). This work aims to explain the issues facing current privacy preservation strategies in big data and to give a comprehensive evaluation of them. This study also introduces new approaches to privacy preservation in big data, such as quick anonymization of massive data streams, identity-based anonymization, differential privacy, privacy preserving big data publishing, and hiding a needle in a haystack. This study discusses big data privacy and security issues in healthcare. A comparative analysis of some contemporary large data privacy approaches is also conducted. A comparative analysis of the latest big data privacy approaches is also conducted.

Authors: Lourenço Yanka , Aparecida dos Santos Carolina , Corrêa Furtini Ana Carolina , Mendes Lourival , Guimarães Junior José Benedito
Published: May 2024

As an alternative for the partial replacement of synthetic adhesives are the modifications that occur still during their synthesis, to improve and adhere new properties. Among the possible materials used in nanoscale, talc is a mineral material of natural origin and a promising raw material due to its low cost, lightness, natural hydrophobicity. Due to the scarcity of studies with the insertion of nanotalc in adhesives, this study aimed to produce plywood panels bonded with phenol-formaldehyde adhesive nanomodified with talc to evaluate its physical-mechanical resistance when compared to conventional synthetic adhesives. To carry out this study, three Pinus oocarpa trees with 28 years of age were used. Different concentrations of talc were used in the formulation with the phenol-formaldehyde adhesive, being the treatments 0; 0,05; 1; 1,5 and 2 % of talc (mass/mass) in relation to the adhesive, with three panels per treatment, totaling 15 panels. The pressing time was 8 minutes with temperature of 160 ºC and pressure of 1 MPa. The physical-chemical characteristics of the lignocellulosic material and of the plywood panels were determined. The quality of the adhesive produced was demonstrated by its resistance to water absorption with the insertion of up to 2 % talc to the adhesive, reducing it considerably. From 1 % talc inserted, the plywood panels had their mechanical characteristics superior to those glued with pure phenol-formaldehyde adhesive. However, as the study is innovative in nature, further research should focus on the application and quality evaluation of other talc nanomodified adhesives on different types of wood panels.

The Need for Social Developmental Research on Internal and External Motivation to Respond Without Prejudice
Authors: Pitcher Katelyn J. , Smith Rhiannon
Published: May 2024

Racial bias peaks during middle childhood. The development of internal
motivation to respond without prejudice (internal MRWP; i.e., a desire
to act according to internalized beliefs about racial equality) and
external motivation to respond without prejudice (external MRWP; i.e.,
the desire to appear non-prejudicial in order to avoid social censure or
rejection) may help to reduce children’s racial bias. However, internal
and external MRWP have almost exclusively been studied among adults. The
current review seeks to situate adult internal and external MRWP
research within established developmental psychological theories in
order to provide a framework for needed developmental research in this
area. We consider peer group norms, same- and cross-race friendships,
and schools as possible contexts for internal and external MRWP
development in middle childhood. Given the urgent threat that racial
prejudice poses to society, better understanding the development of
motivations to respond without prejudice from early in life is critical.
Factors affecting seedling establishment in a warm-temperate secondary forest affected by oak wilt disease
Authors: - Celegeer , Watanabe Naoto , Otani Kanae , Okada Tomoya , Matsushita Michinari , Nakagawa Michiko
Published: May 2024

Diseases are major natural disturbances to forest ecosystems that cause
changes to overstory tree structure and influence seedling dynamics by
altering environmental conditions via functional traits. Thus,
identifying the factors affecting seedling dynamics would improve the
broader understanding of the seedling regeneration process after disease
disturbance. We investigated 13,010 current year seedlings from 59 woody
species, 44 genera, and 21 families following Japanese oak wilt disease
(JOW) in 2009–2013 and 2018–2020 in a Japanese warm-temperate
secondary forest. We also quantified temporal changes in canopy openness
and soil moisture. Structural equation model (SEM) was used to explore
the effects of environmental conditions and seedling functional traits
on current year seedling density in autumn. Canopy openness gradually
increased, whereas soil water content decreased throughout the study
site. After 3‒5 years of disruption by JOW, the recruitment of current
year seedlings increased through improvements in light conditions. The
recruitment of non-current year seedlings increased after the
improvement of current year seedling emergence. The functional traits of
current year seedlings were likely to be affected by soil nutrients in
the late JOW period, whereas litterfall production influenced the
functional traits of current year seedlings in the post-JOW period.
Factors affecting seedling density varied as environmental conditions
changed across the JOW periods. Seedling establishment was enhanced by
increased canopy openness in the late JOW period and by low litterfall,
high soil nutrient content, and high soil moisture in the post-JOW
period. The lack of any direct effect of seedling functional traits on
seedling density might be associated with extensive changes in abiotic
conditions caused by JOW disturbance. Our study provides evidence that
the temporal changes in environmental conditions and seedling densities
occurring after disruption by JOW differed from the changes in forests
impacted by other natural disturbances.

According to the characteristics of variable operating conditions and high
exhaust temperature of the refrigeration system of the refrigerator truck,
the change of the superheat at the outlet of the evaporator is adjusted by a
new electronic expansion valve, and a performance test-bed using the R404A
refrigerant is built to study the influence of the superheat at the outlet
of the evaporator on the performance of the refrigeration system of the
refrigerator truck. The results show that in the process of increasing the
superheat at the outlet of the evaporator, the outlet temperature of the
evaporator increases and the evaporation temperature decrease, the cooling
capacity of the system is reduced by 8.4%, and the COP of the system
increases first and then decreases; At this time, the optimal superheat at
the evaporator outlet is 6?C, and the system COP reaches the optimal value
of 2.856.

The overwhelming flow of information as a consequence of technological development occasionally makes some people confused about whether the information circulating is true or not. Responding to such conditions, the role of pesantren (Islamic traditional boarding school), including its santris (pesantren students), is crucial. Hopefully, santri can contribute to responding to the current development, among others through writing activities. Their articles are expected to provide positive information to fulfill media space. In order to have motivation and capability in writing, a santri should practice various kinds of writings, including journalistic writing.

Salah satu calon Presiden Indonesia 2024, Prabowo Subianto, yang dahulu dikenal sebagai sosok tegas dan berwibawa kini viral di media sosial dengan citra gemoy dan suka berjoget. Kontradiksi branding yang ditampilkan ini menarik untuk dieksplorasi lebih jauh terkait bagaimana strategi manajemen impresi yang dilakukannya dan bagaimana media digital berperan dalam proses tersebut. Teori Dramaturgi yang diperkenalkan Erving Goffman digunakan sebagai pendekatan untuk memahami fenomena ini. Penelitian ini menggunakan paradigma konstruktivis dengan pendekatan kualitatif berupa analisis teks dengan metode analisis multimodal. Dari hasil analisis didapatkan strategi yang digunakan dalam mengkonstruksikan citra baru Prabowo Subianto melalui media sosial. Penelitian ini juga membahas munculnya insiden dramaturgi yang mengganggu manajemen impresi yang telah dijalankan. Penelitian ini menunjukkan peran penting media digital yang dapat berdampak positif maupun negatif terhadap manajemen impresi. Selain itu, khalayak bukanlah objek pasif yang menerima begitu saja kesan yang diterima, tetapi dapat secara aktif mencari kebenaran dengan bantuan media digital. Peran khalayak dan media digital ini perlu dijadikan sebagai kajian dalam manajemen impresi, tidak hanya untuk mencegah munculnya insiden dramaturgi, tetapi juga menghadapi insiden dramaturgi yang telah telanjur terjadi.
 
One of the 2024 Indonesian presidential candidates, Prabowo Subianto, who was previously known as a firm and authoritative figure has now gone viral on social media with his cheerful image and likes dancing. This drastic change in the image is interesting to explore further to find out how impression management strategy is done and how digital media plays a role in this process. The Dramaturgical theory introduced by Erving Goffman is used as an approach to understanding this phenomenon. This research uses constructivist paradigm with qualitative approach in the form of text analysis with multimodal analysis methods. From the results of the analysis, the strategies used in constructing Prabowo Subianto's new image through social media were obtained. However, in the middle of implementing this strategy, dramaturgical incidents arose which disrupted the impression management that had been carried out. This research shows the important role of digital media which can have a positive or negative impact on the implementation of impression management. In addition, audiences are not passive objects who simply accept the impressions they receive, but can actively seek the truth with the help of digital media. The role of audiences and digital media needs to be used as a study in impression management, not only to prevent dramaturgical incidents from occurring, but also to deal with dramaturgical incidents that have already occurred. Thus, developing an impression management strategy should not only focus on how to construct the desired reality, but also how to prevent and act when dramaturgical incidents that disrupt impression management occur.
