This chapter discusses rapid learning health care as an approach to enable customized radiotherapy. It describes a 4-phase methodology: 1) collecting diverse patient, treatment and outcome data, 2) developing prediction models using machine learning to analyze the data, 3) applying the models in clinical practice via decision support systems, and 4) evaluating predicted vs actual outcomes. The goal is to improve treatment predictability and ensure patients receive optimal therapy while efficiently using resources. Next steps involve including patient preferences in decision making for personalized cancer care.
This study compares 8 models for cervical cancer screening in Manitoba to determine the most cost-effective approach. The models vary screening methods (Pap tests, liquid-based cytology, HPV tests), testing schedules, and age ranges. The objective is to report the costs of newer screening technologies compared to the current baseline model. By focusing on direct healthcare costs from the government perspective, the study aims to inform public policy decisions around optimizing cervical cancer screening with limited resources.

Abstract
The goal of this talk is to discuss the role of data standards, and specifically the Digital Imaging and Communication in Medicine (DICOM) standard, in supporting radiomics research. From the clinical images, to the storage of image annotations and results of radiomics analysis, standardization can potentially have transformative effect by enabling discovery, reuse and mining of the data, and integration of the radiomics workflows into the healthcare enterprise.
The document discusses several topics related to imaging in healthcare:
1) Stage 2 MU requirements call for remote viewing of patient records and images to increase access for physicians and patients. Patient portals may play a larger role in remote monitoring programs for chronic conditions.
2) Clinical decision support and CPOE are now required to improve safety, eliminate errors, and justify expensive tests. VNAs can enable remote access via mobile devices.
3) The future is moving from hospital-centric, episodic, fee-for-service care to being more patient-centric, continuous, and value-based with an emphasis on wellness in addition to sickness.

Hunting for Elusive Targets, Markers, Signals & PathwaysJim Smurro
This document summarizes Jim Smurro's presentation at MassBio in 2013 on hunting for elusive targets, markers, signals, and pathways with various imaging and data analysis techniques.
The presentation discusses using multi-modal, multi-scalar imaging and data integration through visual neural networking and clinical cognitive vismemes. This allows for fusion of anatomic, cellular, and molecular imaging with other omics data streams. Tools like computer-assisted detection and augmented pattern recognition can further enhance analysis by multi-disciplinary expert teams.
Shared semantic tags and annotated images enriched with quantitative data can be exchanged over collaborative networks. This facilitates earlier detection, diagnosis, treatment and monitoring of chronic disease by combining phenotypic and genomic information for personalized precision
This document proposes using a DenseNet-II neural network model to classify mammogram images as benign or malignant. It first preprocesses mammogram images through normalization and data augmentation. It then improves the original DenseNet model by replacing the first convolutional layer with an Inception structure, creating a new DenseNet-II model. This model, along with other common models, are tested on mammogram data and the DenseNet-II model achieves the highest average accuracy of 94.55% for benign-malignant classification.

Ultrasound imaging has not been fully integrated into PACS systems compared to other modalities like CT and MRI. A survey of ultrasound radiologists found that:
1) Only 53.2% rated their PACS experience for ultrasound as high, significantly lower than for CT (85.2%), MRI (84.4%), and radiography (83.2%).
2) Ultrasound-specific functions like displaying 3D volumes (0.9% rating) and managing data (29.8% rating) received much lower scores than basic functions like viewing black-and-white images (92% rating).
3) Most respondents felt ultrasound-specific functions needed to be implemented or improved in P
Intra Report- St. James' Hospital Medical Physics Muhammad Alli
The MPBE department (Medical Physics and Bioengineering) provides technical services to the hospital by taking care of medical equipment, the calibration of imaging equipment as well as services to ensuring the safe operation of equipment. The medical physicists also provide services in nuclear medicine. Radioiodine therapy is a service the hospital provides, one of my major goals setting out to work at St. James’s was to learn about radiotherapy, I had a role looking though research papers to try and find information which could help with the way the radioiodine therapy the hospital provides is given, that role was elegantly supported with other relevant work, such as contamination monitoring and experimental work which built an amazing knowledgebase for me. I took part in the NIMIS project and delivered a presentation on a new piece of dose tracking software to the MPBE department.
I carried out many other short term roles which served to develop me in many areas within and including science, IT and engineering as well as developing my people skills. I learned how to interact on a technical level with an interdisciplinary team. As well as gain an understanding of team dynamics, organizational and project management. The experience was very enriching all-around and I would gladly recommend it to future students as an INTRA placement.
This document provides an overview of clinical trial accrual challenges and discusses how social media could potentially help address some of these challenges. It summarizes the National Clinical Trials Network (NCTN) and reviews major accrual barriers experienced by institutions, investigators, and patients. These include a lack of trial awareness, preference for standard care over trials, and concerns about side effects. The document then describes NCI's use of Twitter to promote NCTN trials and poses questions about how social media could enhance awareness of cancer clinical trials.

An example project used CRISPR libraries in prostate cancer cell lines to identify new regulators of androgen receptor stability, which could provide novel treatment targets for castrate resistant prostate cancer.
IRJET- Intelligent Prediction of Lung Cancer Via MRI Images using Morphologic...IRJET Journal
The document describes a proposed system to intelligently predict lung cancer using MRI images and morphological neural network analysis. The proposed system uses a three-stage approach: preprocessing MRI images, extracting features using wavelet decomposition and normalization, and classifying tissues as normal or abnormal using a morphological neural network with image pruning. This combination of morphological image processing and neural networks is intended to more efficiently classify cancer cells and identify affected regions than previous methods.
This document discusses how in vivo imaging can be used to understand the distribution of candidate compounds in the body. It provides examples of how various imaging modalities such as positron emission tomography (PET), near infrared imaging, and mass spectrometry imaging can be used to track the accumulation of compounds in organs, penetration into tissues, and ability to cross barriers like the blood brain barrier. The document emphasizes how imaging can accelerate drug development by providing visualization of biological processes and quantifying pharmacokinetics, target engagement, and toxicity.
University of Toronto - Radiomics for Oncology - 2017Andre Dekker
This document contains the slides from a lecture on radiomics for oncology given by Andre Dekker. The lecture covers the rationale for radiomics, which is to use quantitative features extracted from medical images to help predict outcomes like tumor behavior, survival, and response to treatment using machine learning. The major workflow steps of radiomics are discussed, from image acquisition and feature extraction to modeling and validation. Key challenges like robust segmentation and feature reproducibility are also addressed. New directions for radiomics research include applications in preclinical studies, other modalities like PET and MRI, and linking radiomic features to genomic data. Overall, radiomics holds promise to help personalized medicine but large amounts of standardized data are still needed for proper validation of models.

This document discusses the need for improved imaging systems for breast cancer research using animal models. It introduces a new micro-ultrasound system that allows researchers to non-invasively collect longitudinal data on tumor size, volume, vascularity and perfusion over an animal's lifespan. This significantly reduces the number of animals needed for research. The system has been adopted by leading cancer research institutions and numerous studies have been published demonstrating its ability to accurately track tumor growth and response to therapies.
Breast cancer research in animal models has long been hindered by the lack of a fast, portable, high resolution, research and animal focused imaging system that can visualize 2D tumor size, 3D tumor volume, neoangiogenesis and blood perfusion in vivo, in real-time and most importantly, non-invasively.

This editorial discusses a study that uses survival modeling to predict the benefits of adjuvant chemoradiotherapy for patients with resected gallbladder cancer. The editorial makes three key points:
1) Computer modeling can help address gaps in clinical cancer research when randomized controlled trial data is limited, by using existing data to generate individualized survival predictions and treatment benefit estimates.
2) The gallbladder cancer study demonstrates how modeling can provide guidance for clinical decisions and research directions when high-quality evidence is lacking.
3) Models must be rigorously developed and validated, but can complement clinical trials by extending findings to new populations and longer time horizons not feasible in trials.

Drug discovery and evaluation safety and pharmacokinetic assaysSpringer
MRI can be used to noninvasively measure liver volume in rats over multiple time points, reducing animal usage compared to terminal procedures. A high-resolution 3D MRI scan is used to segment the liver in images, and liver volume strongly correlates with wet liver weight. Respiratory triggering during acquisition improves accuracy. MRI allows longitudinal studies where the same animals act as their own controls, increasing statistical power and reducing group sizes compared to sacrificing animals at each time point.

Revolutionizing Cancer Research Immunohistochemistry and Digital Slide Scanne...ihc-prs
In the ever-evolving landscape of cancer research, two key players have joined forces to enhance our understanding of the disease – immunohistochemistry (IHC) and digital slide scanners. This dynamic duo is reshaping the way researchers visualize and analyze cancer tissues, offering unprecedented insights into the molecular intricacies of tumors.
The document discusses several use cases for applying data mining and machine learning techniques in healthcare and biomedical research. Three examples are:
1) Early diagnosis of cancers like lung cancer and breast cancer through predictive modeling of patient data to detect cancers at earlier stages when survival rates are higher.
2) Predicting patient responses to drug therapies for cancers like breast cancer by combining different types of molecular profiling data using techniques like support vector machines and random forests.
3) Using imaging data and temporal analysis of metrics like medication purchases to better understand and predict chronic diseases like diabetes and associated health complications.
Breast cancer diagnosis via data mining performance analysis of seven differe...cseij
According to World Health Organization (WHO), breast cancer is the top cancer in women both in the
developed and the developing world. Increased life expectancy, urbanization and adoption of western
lifestyles trigger the occurrence of breast cancer in the developing world. Most cancer events are
diagnosed in the late phases of the illness and so, early detection in order to improve breast cancer
outcome and survival is very crucial.
In this study, it is intended to contribute to the early diagnosis of breast cancer. An analysis on breast
cancer diagnoses for the patients is given. For the purpose, first of all, data about the patients whose
cancers’ have already been diagnosed is gathered and they are arranged, and then whether the other
patients are in trouble with breast cancer is tried to be predicted under cover of those data. Predictions of
the other patients are realized through seven different algorithms and the accuracies of those have been
given. The data about the patients have been taken from UCI Machine Learning Repository thanks to Dr.
William H. Wolberg from the University of Wisconsin Hospitals, Madison. During the prediction process,
RapidMiner 5.0 data mining tool is used to apply data mining with the desired algorithms.
This document summarizes an application brief about using micro-ultrasound to study cancer angiogenesis. It discusses how micro-ultrasound allows researchers to non-invasively visualize 3D tumor volume, neoangiogenesis, and blood perfusion over time in small animal models. This helps researchers better understand cancer development and anti-angiogenic therapies. VisualSonics' micro-ultrasound systems provide high resolution real-time imaging of tumor growth and vascularity to help reduce the number of animals needed for research.
Tumor angiogenesis is currently one of the key focal points in biomedical research. It is based upon the hypothesis laid out by Judah Folkman in 1971 that neovasculature is needed to support the growth and metastasis of tumors, and thus anti-angiogenic treatment might be an effective way to cure cancer. Genentech’s anti-VEGF-A drug Avastin a great demonstration of this concept, generating more than $2.7 billion of sales in 2008.
- National challenges in cancer research include lowering barriers to data access and analysis, and integrating clinical and basic research data to enable improved outcomes.
- Disruptive technologies like high-throughput biology and ubiquitous computing are generating large amounts of molecular and clinical cancer data.
- The NCI is working to build infrastructure like the Genomics Data Commons and Cloud Pilots to make these data widely accessible and support data analysis.
- The goal is to develop a national "learning health system" that applies insights from real-world cancer data to research and clinical practice to continuously improve patient care and outcomes.
One health condition that is becoming more common day by day is diabetes.
According to research conducted by the National Family Health Survey of India, diabetic cases show a projection which might increase to 10.4% by 2030.

Muktapishti is a traditional Ayurvedic preparation made from Shoditha Mukta (Purified Pearl), is believed to help regulate thyroid function and reduce symptoms of hyperthyroidism due to its cooling and balancing properties. Clinical evidence on its efficacy remains limited, necessitating further research to validate its therapeutic benefits.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.
