medical literature. These systems can provide evidence-based suggestions and help
with the creation of individualized treatment plans by combining knowledge from a
variety of sources, including clinical guidelines, research publications, and real-time
patient data [47]. This not only improves the precision and effectiveness of diagnosis
but also encourages standardization of treatment procedures and lowers clinical
decision-making variability.
There are issues that need to be resolved despite the enormous promise of AI in
the diagnosis of NAFLD. For the purpose of developing reliable AI models, it is
essential to have access to a variety of high-quality datasets, and the absence of
standardized data-collecting procedures and annotated datasets continues to be a
major barrier
8.3.3 Treatment and management of non-alcoholic fatty liver disease with artificial
intelligence
NAFLD is a prevalent and growing health concern worldwide. NAFLD has
emerged as a major contributor to chronic liver disease due to the rising incidence
of obesity and metabolic syndrome. A comprehensive strategy that emphasizes
lifestyle changes, such as food and exercise, as well as pharmaceutical therapies is
needed for the management and treatment of NAFLD. However, new developments
in AI have demonstrated significant promise in terms of enhancing the diagnosis,
prognosis, and customized management of NAFLD [48].
One of the key areas where AI can aid in the management of NAFLD is in the
diagnosis and early detection of the disease. AI algorithms are now able to interpret
medical imaging data from ultrasound, CT, and MRI to precisely detect and
measure hepatic steatosis, a defining characteristic of NAFLD. This can enable
healthcare providers to detect NAFLD at an early stage when interventions are most
effective [49]. Furthermore, AI algorithms may examine a massive quantity of
patient data, including medical history, test findings, and genetic data, to forecast
the likelihood that the condition will worsen and that problems would arise in
NAFLD patients. AI algorithms are able to create risk ratings and give individualized risk stratification for specific patients by fusing several data sources. The use
of this data by healthcare professionals can improve patient outcomes by assisting
them in prioritizing high-risk patients for additional assessment and intense
management. In terms of treatment, AI can assist in the development of personalized therapeutic strategies for patients with NAFLD [50]. AI models can find
patterns and correlations that might inform therapy choices by examining vast
datasets of patient characteristics, treatment results, and medication reactions. For
example, based on the features of the patient and genetic variables, AI algorithms
can assist in predicting the reaction to particular drugs, such as vitamin E or
pioglitazone. This personalized strategy can improve treatment results and lower the
chance of negative consequences [51].
Additionally, patients with NAFLD can benefit from lifestyle therapies supported
by AI-powered solutions. In order to offer real-time feedback and specific suggestions, these systems can evaluate food and exercise data obtained via wearable

technology or smartphone applications. By monitoring the patient’s adherence to a
healthy diet and exercise regimen, AI algorithms can promote behaviour changes
and help patients achieve their goals. This continuous support can improve patient
compliance and long-term treatment outcomes [52].
Another promising application of AI in NAFLD management is the development
of virtual patient models. These models, based on AI algorithms, can simulate the
progression of NAFLD and assess the impact of different interventions on disease
outcomes [52]. By integrating patient-specific data, such as liver function tests,
imaging results, and lifestyle factors, these models can predict the long-term effects
of interventions, such as weight loss or medication use. Virtual patient models can
serve as valuable decision-support tools for healthcare providers, enabling them to
make informed treatment decisions and evaluate the potential benefits and risks of
different interventions.
8.3.4 Artificial intelligence-enabled non-alcoholic fatty liver disease surveillance and
prevention
The issues related to NAFLD can be greatly improved with the use of AI, which has
become an effective tool in disease surveillance and prevention. NAFLD is a
disorder marked by the build-up of extra fat in the liver and is frequently associated
with obesity, a poor diet, and sedentary lifestyles [35]. It has become a global health
concern, affecting millions of people worldwide. AI-enabled approaches can
revolutionize the management of NAFLD by improving early detection, risk
prediction, personalized treatment plans, population-level surveillance, decisionsupport systems, and patient education and behaviour modifi cation. One of the
significant advantages of AI in NAFLD is early detection. AI algorithms are
capable of quickly and accurately analyzing medical imaging data from CT scans,
MRIs, and ultrasounds [53]. AI algorithms may assist medical professionals in
starting effective therapies by identifying NAFLD symptoms at an early stage, such
as liver fat accumulation and in fl ammation. Early detection is crucial because it
allows for the implementation of lifestyle modifications, such as dietary changes and
exercise, which can prevent disease progression and reduce the risk of complications,
including liver cirrhosis and hepatocellular carcinoma. Moreover, AI can play a
pivotal role in predicting the risk of NAFLD development. By analyzing a
combination of genetic, environmental, and lifestyle factors, AI models can assess
an individual’s likelihood of developing NAFLD [54]. The capacity to forecast risk
might assist healthcare workers in locating high-risk patients who can profit from
specialized preventative actions. For example, individuals with a high genetic
predisposition to NAFLD can be provided with personalized counselling on lifestyle
modifications, including diet and exercise, to mitigate their risk [55].
AI can also contribute to the development of personalized treatment plans for
NAFLD patients. AI algorithms can suggest customized treatment plans by
integrating and examining diverse patient-specific data, such as medical history,
genetic data, and lifestyle variables. These personalized treatment plans can
optimize outcomes by considering individual characteristics and response patterns
8-14

Nanobiotechnology and Artificial Intelligence in Gastrointestinal Diseases
to different interventions. AI may also help in monitoring the effectiveness of the
therapy and making necessary adjustments, ensuring that patients receive the best
possible care. At a population level, AI can enable comprehensive surveillance of
NAFLD. AI algorithms may find patterns, trends, and risk factors related to
NAFLD by examining large-scale health data, such as EHRs and medical claims
databases. Authorities in public health can use this information to better understand
the prevalence and incidence of NAFLD in certain groups and geographical areas.
With this knowledge, targeted prevention programs can be implemented to address
the underlying causes of NAFLD, such as promoting healthier lifestyles and
improving access to healthcare resources [56].
AI-powered decision-support systems have the potential to enhance clinical
decision-making in NAFLD management. Such networks can offer real-time advice
to doctors and nurses by fusing patient-specific data with the most recent findings,
clinical recommendations, and professional expertise. These recommendations,
which might include monitoring advice, treatment alternatives, and diagnostic ideas,
guarantee that professionals have access to the most recent data when making
crucial decisions regarding patient care. Better patient outcomes may result from
increasing the precision and consistency of diagnosis and treatment regimens [55].
Furthermore, AI-enabled tools can empower patients to actively participate in the
management of their NAFLD. Personalized instruction, medication adherence
reminders, food advice, and lifestyle coaching may all be provided through mobile
applications and virtual assistants. By providing patients with accessible and userfriendly tools, AI can support behaviour modification and encourage healthier
choices. These tools can also facilitate remote monitoring and communication
between patients and healthcare providers, enabling more efficient and proactive
care management. In order to fully utilize AI in disease surveillance and prevention,
collaboration between academics, healthcare professionals, policymakers, and
technology developers is necessary. This will eventually improve outcomes for
people with NAFLD and other related diseases.
8.4 Artificial intelligence role in hepatocellular carcinoma
AI has emerged as a powerful tool in the management of HCC, the most common
type of liver cancer. Due to its ability to examine big datasets, identify patterns, and
provide insights, AI has the potential to enhance a variety of HCC-related functions,
including early detection, diagnosis, planning of treatments, and prognosis prediction.
By applying machine learning algorithms, AI has the potential to revolutionize the
way HCC is handled, hopefully resulting in improved patient outcomes and specific
therapy [57]. One of the primary applications of AI in HCC is in the field of medical
imaging. In order to assist in the timely detection and diagnosis of HCC, AI
algorithms may evaluate radiological images such as CT scans, MRI, and ultrasound.
These algorithms are able to spot minor signs of HCC such as nodularity, vascularity,
and tumour size. AI is able to help radiologists and doctors in establishing cause and
accurate diagnoses, enabling early intervention, and increasing patient survival rates
by properly and quickly interpreting these pictures. Moreover, AI can aid in the risk
8-15

Nanobiotechnology and Artificial Intelligence in Gastrointestinal Diseases
stratification and prediction of HCC progression [58]. AI models can evaluate the risk
of disease recurrence, metastasis, and therapy response in specific individuals by
combining clinical, genetic, and histological data. In order to make sure that high-risk
patients receive more extensive monitoring and immediate assistance, this information
can assist doctors in creating individualized treatment regimens and surveillance
techniques for HCC patients. Additionally, AI can help in the discovery of new
prognostic markers or genetic signatures that can improve risk assessments and offer
insightful information about patient outcomes [57].
Treatment planning is another area where AI can make a significant impact on
HCC management. AI algorithms can suggest the best treatment plans for certain
patients by examining patient-specific data, such as medical history, imaging results,
and genetic profiles. This involves recommending suitable therapeutic methods, such
as surgical resection, liver transplantation, radiofrequency ablation, or systemic
medicines like targeted therapies or immunotherapies [59]. Additionally, AI can help
anticipate therapy responses and track the evolution of the disease, allowing for
prompt modifications to the treatment plan to enhance therapeutic efficacy. AI can
also help forecast the prognosis and survival of individuals with HCC. AI algorithms
may produce customized survival estimates for specific patients by evaluating largescale datasets and taking into account a variety of prognostic variables. This can
offer important insights into long-term results, assist both doctors and patients in
making well-informed decisions about available treatments, and help set reasonable
expectations. AI can also aid in identifying novel prognostic markers or genetic
signatures that could further refine prognostic predictions in HCC [60].
Furthermore, AI has the potential to support precision medicine in HCC. AI
algorithms can find possible therapy targets, biomarkers, and medication combinations that may be efficient in particular subgroups of HCC patients by examining
comprehensive genomic and molecular data. This personalized approach to treatment can optimize therapy selection and improve treatment outcomes. By analyzing
huge datasets and making predictions about treatment effectiveness based on
molecular profiles, AI can also make it easier to find new drug candidates, possibly
leading the way for the creation of suited medicines.
8.4.1 Limitations of the traditional method for the diagnosis and treatment of
hepatocellular carcinoma
HCC is a kind of liver cancer that can be efficiently managed, but current
approaches to detection and therapy have numerous drawbacks. These restrictions
cover a wide range of topics, such as diagnosis, the degree of procedure invasiveness,
accuracy, early identification, treatment alternatives, recurrence rates, and customized treatment plans. The late-stage diagnosis of HCC is one of the main drawbacks
of the conventional method. Often, this type of cancer remains asymptomatic in its
early stages, making it difficult to detect. As a result, HCC is frequently discovered
in individuals after the tumour has already migrated to other regions of the liver or
surrounding organs [61]. The likelihood of effective therapy and overall patient
survival is greatly decreased by late-stage diagnosis. In addition to delayed
8-16

Nanobiotechnology and Artificial Intelligence in Gastrointestinal Diseases
detection, traditional diagnostic methods for HCC can be invasive and carry risks.
Liver biopsy, a commonly used procedure for diagnosing HCC, involves extracting
a small sample of liver tissue for examination. However, this procedure can be
uncomfortable for patients and carries a risk of complications such as bleeding or
infection. Moreover, the obtained sample may not fully represent the characteristics
of the tumour due to tumour heterogeneity, leading to potential inaccuracies in
diagnosis [62].
For the diagnosis of HCC, imaging methods MRI, CT, and ultrasound are also
used. The ability to identify tiny tumours, distinguish HCC from other liver diseases,
and precisely estimate the degree of tumour involvement are all limitations of these
techniques. This lack of sensitivity and specificity can result in misdiagnosis or
delayed diagnosis, further hindering effective treatment. The lack of trustworthy
early detection markers for HCC is another major constraint. HCC lacks the distinct
biomarkers that some other cancers do that can be used for early diagnosis. As a
result, effective screening tests for early detection are limited or nonexistent. This
limitation contributes to the late-stage diagnosis mentioned earlier, reducing treatment options and overall prognosis for patients [63].
Also, there are frequently few standard alternatives for treating HCC, particularly in advanced stages or for individuals who cannot have a surgical resection.
Although chemotherapy and radiation treatment are frequently utilized, their
efficacy may be restricted since HCC cells have a built-in resistance and there is a
chance that they might harm nearby good liver tissue. These limitations necessitate
the exploration of alternative and more targeted therapies to improve treatment
outcomes. Recurrence rates are high in HCC, even after successful treatment.
Traditional approaches, on the other hand, might not be able to monitor for
recurring disease as efficiently, leading to delays in discovery and proper response.
Close surveillance is crucial in HCC patients, but the limitations of traditional
methods may hinder the timely identification of recurrent tumours [64].
Moreover, the traditional approach to HCC diagnosis and treatment lacks
personalized strategies. Decisions regarding treatment are frequently made in accordance with broad standards, which may not take into account the unique variances in
tumour features, patient comorbidities, or genetic variables. This restriction makes it
difficult to create treatment regimens that are specifically catered to the needs of each
patient, which may have an impact on the effectiveness and results of the therapy [65].
These limitations encompass late-stage diagnosis, invasive diagnostic procedures,
limited sensitivity and specificity of imaging techniques, lack of early detection
markers, limited treatment options for advanced stages, high recurrence rates, and
the absence of personalized treatment strategies. However, ongoing advancements in
medical research and technology offer hope for overcoming these limitations and
improving the diagnosis, treatment, and overall management of HCC.
8.4.2 Artificial intelligence with hepatocellular carcinoma diagnosis
AI has emerged as a powerful tool in the diagnosis of HCC, the most common type
of primary liver cancer. AI has the potential to increase the precision and
8-17

Nanobiotechnology and Artificial Intelligence in Gastrointestinal Diseases
effectiveness of HCC diagnosis, resulting in better patient outcomes. AI has the
capacity to evaluate complicated medical data and identify patterns that may escape
human observers. One of the primary applications of AI in HCC diagnosis is in the
analysis of medical images [60]. The identification and characterization of HCC
depend heavily on imaging methods including CT, MRI, and ultrasound. In order to
identify patterns and traits indicating HCC, AI systems may be trained on huge
collections of medical pictures. Radiologists may more easily discover and diagnose
HCC at an early stage when treatment choices are more successful by using AI to
apply these algorithms to fresh patient images [58]. Furthermore, AI can assist in the
quantification and characterization of liver lesions. AI algorithms are able to
estimate tumour size, evaluate vascular invasion, and find other significant aspects
in radiological images that assist diagnose the stage and severity of HCC. This
information is crucial for treatment planning and prognosis. By comparing patient
photos to a sizable library of annotated images, AI-powered systems may also offer
decision assistance, giving doctors insights and suggestions for more accurate
diagnosis and treatment choices [66].
In addition to medical imaging, AI can leverage other sources of patient data to
improve HCC diagnosis. A wide range of information is stored in EHRs, such as
patient demographics, medical histories, test results, and pathology reports. These
records may be searched through AI algorithms, which can then produce prediction
models for the growth and progression of HCC. By considering a wide range of data
points, AI can assist doctors in identifying high-risk individuals who may benefit
from closer monitoring or earlier intervention. With the help of AI and biomarker,
early or accurate diagnosis of the HCC can be acchived. Several potential
biomarkers are listed in table 8.1. Moreover, AI has the potential to contribute to
personalized medicine in HCC diagnosis [67]. AI systems can pinpoint certain
biomarkers and genetic alterations linked to HCC by combining genetic and
molecular data. Based on each patient’s particular molecular profile, this information can help in customizing treatment approaches, such as targeted treatments or
immunotherapies, for that patient. AI can also facilitate the prediction of treatment
response and prognosis, enabling healthcare professionals to optimize therapeutic
strategies and improve patient outcomes.
While AI shows great promise in HCC diagnosis, it is important to address
certain challenges and considerations. One challenge is the need for high-quality,
diverse, and well-annotated datasets to train AI algorithms effectively [68].
Collaborative efforts are required to collect and curate comprehensive datasets
that reflect the heterogeneity of HCC, encompassing different stages, etiologies, and

demographic factors. AI can assist healthcare professionals in accurate diagnosis,
prognostication, and treatment planning for HCC. While challenges exist, continued
research, collaboration, and ethical considerations will pave the way for responsible
and effective integration of AI in HCC care, ultimately improving patient outcomes
and advancing our understanding of this complex disease.
8.4.3 Treatment and management of hepatocellular carcinoma with artificial
intelligence
HCC is the most common type of primary liver cancer, and it poses a significant
health challenge globally. It is essential to look into cutting-edge methods for the
treatment and management of HCC because its incidence has been rising and its
prognosis is still dismal. Personalized treatment plans, early identification, and
monitoring of therapy response are just a few of the areas of cancer care that have
been revolutionized by AI in recent years. The use of AI in the management and
treatment of HCC has the potential to significantly improve patient outcomes and
lessen the burden of this fatal condition [69]. Early detection of HCC is essential for
effective therapy because it enables prompt intervention when the tumour activity is
still confined and relatively mild. AI-based algorithms have demonstrated remarkable
capabilities in interpreting medical images, such as CT scans, MRI, and ultrasound,
with higher accuracy and efficiency than traditional methods. AI can help radiologists
discover and characterize HCC abnormalities more precisely, lowering the possibility
of a missed diagnosis and allowing quick referral to experts [70]. This is done by
utilizing machine learning and deep learning approaches. Once HCC is diagnosed,
treatment decisions become complex due to variations in tumour characteristics,
patient factors, and available therapeutic options. Here, AI can play a pivotal role in
assisting clinicians with personalized treatment recommendations. By analyzing vast
amounts of patient data, including genomic profiles, clinical history, and treatment
outcomes, AI models can identify patterns and correlations that may predict the most
effective treatment strategies for individual patients. This may result in more
specialized and focused therapy, perhaps improving the effectiveness of the latter
while reducing unneeded adverse effects [71].
The common methods of treatment for early-stage HCC include surgical resection,
liver transplantation, and ablation treatments. However, not all patients are
suitable candidates for these procedures, and disease recurrence remains a significant
concern. AI can help with risk stratification by estimating survival and recurrence
probabilities based on a variety of clinical and biological variables [72]. The use of these
prediction models can help doctors decide on the best course of therapy and posttreatment surveillance tactics. For patients with advanced HCC or those who are not
eligible for curative therapies, systemic treatments like targeted therapies and immunotherapies offer potential benefits. AI can optimize the selection of these therapies by
identifying biomarkers associated with treatment response or resistance. By analyzing
diverse datasets from clinical trials and real-world patient data, AI models can uncover
novel biomarkers and develop predictive models that guide treatment decisions,
ultimately leading to improved outcomes and quality of life for patients [73].

Additionally, tracking the response to therapy is essential to determining its efficacy
and making any required modifications in a timely manner. By analyzing changes in
tumour features and circulating tumour DNA, AI-driven radiomics and liquid biopsy
technologies can detect early disease progression or therapy response. These noninvasive techniques not only eliminate patient discomfort but also give doctors realtime data to modify treatment plans and improve therapeutic results [74].
AI has the potential to boost HCC research and treatment development in
addition to enhancing individual patient care. Through AI-driven analysis of
enormous genomic and molecular databases, the discovery of new therapeutic
targets and the repurposing of current medications may be improved. Virtual
screening of compounds against specific molecular targets can also expedite the
drug discovery process, potentially leading to the development of more effective and
less toxic treatments for HCC [75]. Continued research, collaboration between AI
developers and healthcare professionals, and a strong commitment to ethical
implementation are crucial to unlock the full potential of AI in the fight against
HCC and other forms of cancer.
8.4.4 Artificial intelligence-enabled hepatocellular carcinoma disease surveillance and
prevention
HCC, the most prevalent form of primary liver cancer, presents a major public
health challenge worldwide. Early identification and prevention are essential for
enhancing patient outcomes and lowering mortality because of their high incidence
rates and few therapeutic choices. In recent years, the advent of AI has revolutionized the field of healthcare, offering unprecedented opportunities for disease
surveillance and prevention in HCC [76]. Data collection and aggregation are the
first steps towards AI-driven disease surveillance in HCC. Sophisticated AI
algorithms are built using a large array of patient data, including medical records,
imaging scans, genetic information, lifestyle variables, and environmental exposures. With the help of these potent algorithms, it is possible to analyze patterns and
identify risk factors for the development of HCC. As a result, AI makes it easier to
make more precise predictions, identify people who are at high risk of developing
HCC early on, and implement timely treatments and individualized preventive plans
while also boosting the efficiency of disease surveillance [75].
One of the primary applications of AI in HCC prevention is in the field of medical
imaging analysis. Liver imaging, such as ultrasound, CT, and MRI, plays a crucial
role in early detection and diagnosis. When trained on large datasets of imaging
scans, AI systems can quickly and effectively interpret these pictures, finding even
tiny abnormalities or early-stage malignancies that human observers would miss.
AI-enabled image analysis helps diagnose the disease in its early stages, when
treatment choices are most effective and the chance of survival is better, by
improving the sensitivity and specificity of HCC diagnosis [77]. Another crucial
element of HCC surveillance and prevention is AI-driven genomics. An individual’s
vulnerability to developing HCC is mostly influenced by hereditary factors;
however, genetic markers linked to the disease that were previously unknown can
8-20

Nanobiotechnology and Artificial Intelligence in Gastrointestinal Diseases
now be found using AI algorithms. By analyzing vast genomic datasets, AI can
identify genetic patterns and mutations that elevate the risk of HCC. This provides
insightful information on the fundamental processes underlying the development of
HCC and indicates prospective therapeutic targets for preventative strategies or
cutting-edge therapy modalities [73].
In addition to genetics, environmental and lifestyle factors have a big impact on
how HCC develops. AI can combine various facts to create detailed risk profiles for
each individual. AI models can precisely forecast a person’s probability of acquiring
HCC by taking into account variables including alcohol intake, viral infections like
hepatitis B and C, obesity, and other liver illnesses. Armed with this knowledge,
healthcare professionals may give specific therapy and focused treatments to highrisk patients in an effort to assist them to change their behaviour and reduce their
chance of developing HCC [74].
Moreover, AI is instrumental in analyzing real-time health data from various
sources, particularly with the rise of wearable devices and health monitoring
applications. Continuous tracking of individuals’ health parameters can generate
vast amounts of data that AI algorithms can process in real-time. AI can uncover
early indicators of HCC or illness development by seeing abnormalities and finding
departures from typical health trends. With fast intervention and appropriate
medical care made possible by this real-time analysis, the condition may be stopped
from progressing to more serious stages [78]. AI’s impact on HCC prevention
extends beyond the individual level to address population-level health challenges. AI
may be used by public health authorities to predict and control the prevalence of
HCC on more widespread levels. AI is able to pinpoint high-risk areas and develop
specialized preventative plans by examining population patterns, geographic distribution, environmental variables, and other pertinent data. Implementing broad
screening programs, planning hepatitis vaccination drives, or creating public health
campaigns focused on encouraging better lives and lowering HCC risk factors are a
few examples of these [79].
Through its applications in medical imaging, genomics, real-time health data
analysis, and population-level forecasting, AI offers valuable tools to identify highrisk individuals, implement personalized interventions, and design targeted public
health strategies. The influence of AI technology on HCC prevention holds
tremendous potential for lowering the burden of this terrible disease on a worldwide
scale as it develops and integrates with healthcare systems.

disease severity, and response to therapies. The vast amount of data generated in the
field of hepatology can be effectively analyzed and interpreted by AI, aiding in
prognostication and predicting treatment outcomes. This has led to the development
of more efficient and targeted therapies, ultimately improving the overall quality of
life for patients with hepatitis and chronic liver diseases. Additionally, AI algorithms
can efficiently match donor organs with potential recipients, maximizing the chances
of successful transplants and reducing waitlist times for patients in dire need of a
liver transplant. This has the potential to save countless lives and alleviate the
burden on healthcare systems.

susceptibility and progression, paving the way for more targeted therapies and
personalized medicine approaches. Another future aspect lies in the realm of drug
development. The use of AI-driven drug discovery platforms can accelerate the
identification of potential therapeutic compounds, shortening the time and cost
required to bring new treatments to the market. By simulating molecular interactions and predicting drug–target interactions, AI can revolutionize the pharmaceutical industry and facilitate the discovery of novel treatments for hepatitis and
chronic liver diseases.
However, to fully realize the potential of AI in hepatitis and chronic liver diseases,
several challenges must be addressed. Data privacy and security concerns, ethical
considerations, and the potential for bias in AI algorithms must be carefully
managed to ensure patient safety and maintain public trust. Collaborative efforts
between clinicians, researchers, and AI experts will be crucial in overcoming these
challenges and ensuring that AI technologies are implemented responsibly and
ethically. The integration of AI in hepatitis and chronic liver diseases has already
yielded promising outcomes in diagnosis, treatment, and patient care. As technology
continues to evolve, AI is expected to play an increasingly pivotal role in transforming hepatology and liver medicine. By harnessing the power of AI, we can
aspire to a future where liver diseases are diagnosed early, treated effectively, and
managed with precision, signi fi cantly improving the lives of millions of patients
worldwide.
