A KNOWLEDGE BASED AUTOMATIC RADIATION TREATMENT PLAN ALERT SYSTEMijaia
In radiation therapy, preventing treatment plan errors is of paramount importance. In this paper, an alert system is proposed and developed for checking if the pending cancer treatment plan is consistent with the intended use. A key step in the development of the paper is characterization of various treatment plan fingerprints by three-dimension vectors taken from possibly thousands of variables in each treatment plan. Then three machine learning based algorithms are developed and tested in the paper. The first algorithm is a knowledge-based support vector machine method. If an incorrect treatment plan were offered, the algorithm would tell that the pending treatment plan is inconsistent with the intended use and provide a red flag. The algorithm is tested on the actual patient data sets with 100% successful rate and 0% failure rate. In addition, two algorithms based on the well-known k-nearest neighbour and Bayesian approach respectively are developed. Similar to the support vector machine algorithm, these two algorithms are also tested with 100% success rate and 0% failure rate. The key seems to pick up the right features.
Researchers and care providers wanted to have access to all of the patients` vitals signs (temperature, blood pressure, heart rate, and respiratory rate) but most of this data wasn?t recorded, only a few readings a day were posted to the patients Electronic Medical Record (EMR). The EMR isn`t meant to store such volume of data, let alone to perform any data mining on it. This session will describe the architecture of the solution that was implemented to collect these vital signs automatically from Bedside Medical Devices (BDMI), and store them into a temporary storage, then load them into a Hadoop cluster. The session will also cover how the team married this vital signs data in the HDFS (Hadoop File System) with the rest of the EMR data for our Principles Investigators (PI) in our research institute to search for correlations between administered medications, diagnosis, and vital signs readings. The session will describe the reasons behind the design decisions that were made, such as using a Cloud Hadoop cluster versus on-premises while maintaining HIPAA.

Ontology-Driven Clinical Intelligence: A Path from the Biobank to Cross-Disea...Remedy Informatics
The discovery of clinical insights through effective management and reuse of data requires several conditions to be optimized: Data need to be digital, data need to be structured, and data need to be standardized in terms of metadata and ontology. This presentation describes a bioinformatics system that combines a next-generation biobank management model mapped to applicable international standards and guidelines with a master ontology that controls all input and output and is able to add unique properties to meet the specialized needs of clinicians for cross-disease research.
Interest has increased in the use of prognosis factors as a cursor for breast cancer personalized treatment. For clinicians, early detection of those factors can be helpful for a good management of the disease and for the choice of an efficient treatment. Moreover, it exists a huge amount of meaningful information in pathological reports, biological measurements and clinical information in a patient journey that remain unexploited. In that context, I propose to develop and apply novel machine learning techniques to predict cancer outcome such as recurrence or survival from multi-modal breast cancer patient data (including medical notes in natural languages and the outcome of various lab analyses). For that, I use a deep neural sequence transduction for electronic health records called BEHRT1. This model is inspired from one of the most powerful transformer-based architecture in Natural Language Processing: BERT2.
OPTIMIZED PREDICTION IN MEDICAL DIAGNOSIS USING DNA SEQUENCES AND STRUCTURE I...IAEME Publication
The prediction in medical diagnosis is an important role in the field of bio informatics which acts as a vital tool for handling and maintaining human health care in an efficient way. The technologies involves in the process prediction are al complex ones to integrate and implements in an effective way. The optimized prediction in the medical diagnosis reduces the medical treatment complexities along with the time and cost saving benefits. The DNA (Deoxyribonucleic Acid) sequences and structure information will make the disease diagnosis prediction with more accuracy and optimizations for comparisons and conclusions. For the impact of inheritance based diseases the earlier predictions will definitely act as a pivotal process for improving the cure strategies for any human being. The existence case disease diagnosis based prediction will also help and supports the medical treatment in an advanced way both in technical and process wise. This paper proposed Optimized Prediction in Medical Diagnosis Using DNA Sequences and Structure Information with pattern matching and comparison analysis using DNA sequence and structure information for individual patient condition. In future this paper will be extended with artificial intelligence based implementation through genetic algorithm to attain a DNA based Medical Diagnosis Disease Prediction System.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

2. The Driver
Many entities within Northwestern Medicine (NM) want to
capture data about cancer patients treated at NM.
!
Research
!
Education
!
Operational/Outcomes Analysis
!
QA/QC and Process Improvement
!
Marketing/Branding/Outreach Assessment
3. Challenges
NM has multiple EHR systems: Epic (NMFF), PowerChart
(NMH) and Mosaiq (Radiation Oncology).
Not all clinical systems flow into one of the EHRs
All relevant data is not discretely captured during the course of
clinical care. For example, pathology diagnosis is recorded
in a textual document.
4. Northwestern Medicine Enterprise
Data Warehouse (NMEDW)
The NMEDW is:
One stop shop for finding data from 40+ clinical systems, 10
years of data, and 2.2 Million patients (4 billion events!)
Optimized cross-system data marts representing major
biomedical entities and events: patients, providers,
encounters, labs, medications...and more.
Intelligent structures, data representations, and the ability to
identify and correlate data across patients, events and data
types
5. Who is requesting
change?
The Northwestern Brain Tumor Institute*
SPORE in Prostate Cancer
Lynn Sage Breast Cancer Center
Gastrointestinal Oncology Group
Many others - typically disease-focused
* We will focus mainly on use cases and workflows from BTI
6. What data do they need?
Demographics
Diagnosis
Treatment
Disease Progression
Survival
7. Old Solution
Data coordinator opens up EHR(s) and manually copies data
into a clinical database.
Newer solution: Data coordinator pulls data from reports run
against the NMEDW and copies/extracts/annotates them
into the clinical database
8. Command + Tab Model
A manually curated database disconnected from EHR data.
Depends on a data coordinator finding and manually copying
data from the EHR to a clinical database.
12. Command + Tab Model:
Pros
Depends on humans:
Humans are great at interpreting narrative documentation -where a significant portion of cancer clinical data
(unfortunately) resides.
13. Command + Tab Model:
Cons
Depends on humans:
Difficult for a human to be aware of every relevant
medical event of every patient within a cohort.
Ignores the flux that occurs within EHRs: patient medical
histories merging and splitting.
Humans get bored with rote copying discrete data.
Humans quit and get new jobs.
14. New Solution:
NBTI Data CaptureTool
The NBTI Data Capture Tool automatically pulls (via the
NMEDW) relevant EHR data for each patient.
Data points discretely captured in the EHR need no further
review.
Data points captured non-discreetly in textual documents are
abstracted via natural language process (NLP) and
presented to a data coordinator for review/revision.
15. Why not use reports?
Lots of valuable clinical data still resides in narrative
documents.
Not all discrete data contained within the EHR(s) has
been normalized into easily queryable structures in
the NMEDW.
Today an investigator cannot ask an NMEDW analyst
the question and get a quick result:
How many IDH1 negative glioma patients survived
longer than 5 years?
16. Waiting for Nirvana
NMEDW reports will not obsolete research clinical
databases until:
!
!
Clinical IT optimizes the EHRs to discretely
capture all relevant data points (ain’t happenin’)
The NMEDW normalizes all EHR data into easily
digestible formats and to reference
terminologies (limited by above step!)
17. Sources for the first
iteration
Epic: support discrete data capture of fundamental treatment/
diagnosis data points.
Epic/MyChart: embed intake form.
Cerner: support discrete data capture of pathology data points.
Cerner: support explicit association between pathology cases
and surgeries.
MOSAIQ: support discrete data capture of site, laterality for
radiation therapies:.
19. Analyze the Data
Started with a list of data elements and sample data from a
neuro-oncologist and a neurosurgeon
Determined obtainability of each data element:
!
Discrete in the EHR and in the EDW.
!
Discrete in the EHR but not in the EDW.
!
narrative document in the EHR and in the EDW.
!
narrative document in the EHR but not in the EDW.
20. Build an EDW
Data Mart
Engaged the NMEDW team to build a NBTI-dedicated data mart and
extract transform load (ETL) script:
patients
encounters
medications
surgeries
surgery notes
pathology cases
gamma knifes
radiation therapies
imaging exams
progress notes
labs
21. Build a Clinical Database
Build a clinical database mirroring the structure of the
EDW data mart in a PostgreSQL server
Add database structures to allow for the layering of
curated data on top of data imported from the EDW.
22. Import Data
Expose the data in the EDW data mart as
web services via SQL Reporting Service
reports.
Automate via cron jobs the pull of data
into the clinical database from the EDW
with shared EDW web service adapter
code.
23. Patients
The criteria for inclusion within the NBTI system is
determined by a list of ICD diagnosis codes. Criteria
could alternatively be determined by consent to a
protocol.
Pull from the NMEDW patient name, birth date, MRN(s),
gender, ethnicity, race, death date and last seen date
(across Northwestern Medicine - NM).
24. Integrate with Specimen
Inventory Data
Prepare data for migration into PathCore's specimen
inventory system BSI2.
Allow for ad hoc query exploration of specimen
inventory based on clinical data points.
Standardizing the structure of clinical data captures
across sites makes this possible.
25. NLP
Build an NLP pipeline to abstract from the flow of
narrative documents and textual fragments discrete
data points.
Use the Stanford NLP library for chunking and sentence
splitting.
Use the lingscope library to parse the negation scope of
sentences.
Use the NCI metathesaurus for synonym lookups and
attaching codes
26. Electronic Intake Form
Deploy an electronic intake that can be filled out by a
patient before or at their first clinic visit.
email is sent, can be filled out by web browser, tablet or
(painfully) on a smart phone
29. Biopsy, Surgery and
Pathology Diagnosis
Pull from the NMEDW NM biopsies, surgeries, surgical
procedure reports and pathology cases (inside and out).
Abstract and allow for the confirmation/revision of surgery
type, site, laterality, pathology diagnosis, grade,
recurrence, anatomical location of primary, cancer staging
and pathology test results.
37. Labs and Other
Medications
Labs
•
Pull from the NMEDW NM labs.
Other Medications
•
Pull from the NMEDW NM non-intravenous,
prescribed/ordered medications.
•
Allow for confirmation/revision of drug, route,
duration, amount, patient parameter and
administered.
38. Imaging Exams and Clinic
Visits
Imaging Exams
•
•
Pull from the NMEDW NM imaging exams.
Abstract and allow for confirmation/revision of
response/progression declarations and lesion
measurements.
Clinic Visits
•
Pull from the NMEDW NM clinic visit notes. Abstract
and allow for confirmation/revision of performance
status declarations and tracking of outside treatments.
39. Reporting
Ad-hoc query exploration of data.
Integrate NMH quality metrics.
Generate Kaplan Meier survival curves against SEER
data on demand
