This presentation describes the applications of synthetic data to cancer registries's efforts to support understanding of and research based on cancer while reducing privacy risks to cancer patients.
The Simulacrum imitates some of the data held securely by the Public Health England’s National Cancer Registration and Analysis Service.
The data in the Simulacrum is entirely artificial. It does not contain data about real patients, so users can never identify a real person. It is free to use and allows anyone who wants to use record-level cancer data to do so, safe in the knowledge that while the data feels like the real thing, there is no danger of breaching patient confidentiality.
Basics of Systematic Review and Meta-analysis: Part 1Rizwan S A
This document discusses the basics of conducting a systematic review and meta-analysis, including choosing a novel and interesting topic where evidence is still unclear, writing a protocol according to PRISMA-P guidelines and registering the review, searching various databases and other sources for literature, developing a search strategy and flowchart for study selection, and ensuring an exhaustive literature review by obtaining full texts and contacting authors and experts for unpublished work or additional data.
The document discusses key aspects of research design including:
1) Research design determines the framework and methods for a study including data collection and analysis.
2) Key decisions in research design include determining primary or secondary data sources, qualitative or quantitative data, specific methods for data collection like surveys or experiments, and approaches for data analysis.
3) A strong research design considers reliability, validity, neutrality, and generalizability and sets up a study for success through a coherent plan.
This document provides an overview of systematic reviews and meta-analyses, their application to medication safety data, and how to conduct such reviews. It defines systematic reviews and meta-analyses and explains how they are conducted more rigorously than traditional narratives. Reviews of safety data can help resolve inconsistencies across studies and increase precision through pooling of data. While less common than efficacy reviews, meta-analyses of both randomized trials and observational studies are valuable for understanding adverse events. It is important to search unpublished literature and include various study designs when reviewing safety. Quality assessment and reproducible search methods are also important aspects of conducting a rigorous systematic review or meta-analysis of medication safety data.

It introduces variables, relationships between variables, and data matrices. It describes the differences between observational studies and experiments, and discusses sources of bias and different sampling methods. It covers principles of experimental design such as controlling variables, randomization, replication, and blocking. Finally, it distinguishes between random sampling and random assignment in experiments.
A systematic review is a comprehensive literature review designed to answer a specific clinical question using a pre-defined protocol. It requires at least 12 months to conduct due to extensive searches of published and unpublished studies, validity assessments of included studies, data collection, analysis, and keeping the review up-to-date. In contrast, a traditional literature review does not follow a pre-specified protocol or aim to be comprehensive. Systematic reviews also publish detailed search strategies to allow replication and apply statistical methods like meta-analysis to synthesized data from included studies.

It aims to help reviewers appraise important methodological aspects of a systematic review.
The information needs of Occupational Therapy students - Jane Morgan DanielLISDISConference
This document summarizes a case study on the information needs of occupational therapy students. The study used a mixed methods approach, including questionnaires, to understand what information sources OT students use, why they seek information, and barriers to satisfying their information needs. Key findings included that students seek information for academic assignments, evidence-based practice, and developing workplace skills. They commonly use clinical colleagues, textbooks, search engines, and databases. Barriers included a lack of awareness of library resources and limited knowledge among librarians about occupational therapy. The study recommends increasing awareness of OT as a profession and improving access to and promotion of OT-related resources.
The document discusses the importance of data extraction in systematic reviews and provides guidance on developing effective data extraction forms and processes. Specifically, it outlines that data extraction 1) involves accurately summarizing studies in a common format to facilitate analysis and presentation, 2) identifies numerical data for meta-analyses, and 3) obtains information to assess risk of bias and applicability; and recommends 4) developing structured yet adaptable forms, 5) providing clear instructions, and 6) considering single versus double extraction.
Meta-analysis is a systematic procedure for combining data from multiple studies to arrive at a meaningful conclusion on a topic. It is being included as part of PhD theses, especially in clinical and psychological studies, to strengthen or support thesis results. Perfect Statistics provides top dissertation writing services for scientists, students and pharmaceuticals including meta-analysis, systematic reviews, medical statistics and medical writing projects.
Do Citations and Readership Predict Excellent Publications?Dasha Herrmannova
This document discusses research into whether current metrics like citations and readership are sufficient to identify highly influential papers. The authors created a dataset of 314 papers labeled as either seminal works or survey papers based on a questionnaire. They then used this dataset to classify papers based on citations and readership, finding that citations provided a somewhat better prediction of influence than readership alone. However, neither metric was deemed optimal. The authors conclude that an ideal dataset and alternative metrics that examine citation context and content are needed to better measure research impact.
This document discusses mixed methods research, which involves collecting and analyzing both quantitative and qualitative data within a single study. It provides an overview of the main mixed methods research designs, including convergent parallel, explanatory sequential, exploratory sequential, embedded, and transformative designs. For each design, it outlines the purpose, priority of quantitative and qualitative data collection and analysis, and how the different data sources are integrated. The document also discusses evaluating mixed methods studies and some potential ethical issues to consider in mixed methods research designs.
The document discusses various techniques for analyzing qualitative and quantitative data in research. It describes different types of statistical analysis that can be used for organizing, summarizing, and drawing conclusions from data, including descriptive statistics, correlation analysis, multivariate analysis techniques like multi regression analysis, discriminant analysis and factor analysis. It also discusses using t-tests to analyze experimental research data by comparing experimental and control groups.

Meta-analysis is defined as quantitatively combining and integrating the findings of multiple research studies on a particular topic. It was coined by Glass in 1976 and refers to analyzing the results of several studies that address a shared research hypothesis. The key steps in a meta-analysis involve defining a hypothesis, locating relevant studies, inputting empirical data, calculating an overall effect size by standardizing statistics, and analyzing any moderating variables if heterogeneity exists. An example provided is a meta-analysis on coping behaviors of cancer patients that would statistically analyze results from quantitative studies with similar age groups.

Grounded theory is a qualitative research method that involves collecting and analyzing data to generate a theory. It has several advantages, including allowing researchers to become immersed in the data, requiring systematic analysis, and encouraging interplay between data collection and analysis. Some disadvantages are that it can be difficult to gain funding and it is not designed to test hypotheses. The research process involves developing an initial research question, collecting data through methods like interviews, analyzing the data through coding and memoing, and integrating the analysis to develop theories. Recent research has explored different approaches to grounded theory and its applications.
The document provides an introduction to systematic reviews and meta-analyses. It discusses that systematic reviews aim to reduce bias by comprehensively identifying, appraising, and synthesizing all relevant studies on a topic. They often include a meta-analysis to statistically synthesize data from multiple studies. Systematic reviews use a predefined protocol and search strategy to find all studies, whereas traditional reviews may not consider study quality or report how conclusions follow from evidence. The key steps in a systematic review are developing a protocol, conducting a comprehensive literature search, assessing study eligibility, extracting data, critically appraising studies, and synthesizing results.

Big Data Analytics - It is here and now!Farhan Khan
This study examined how instructional strategies relate to off-task behavior in elementary school students. Researchers observed 22 classrooms and coded student behavior as on-task or off-task. Regression tree analysis found that instructional format and duration impact off-task rates, with some formats engaging students more than others. Small group work and shorter duration activities were associated with less off-task time than individual work or whole class instruction for long periods. The findings provide insights to help design lessons that optimize student focus.

Program Leader, CTSI Biostatistics and Computational Biology
This document discusses different methods for collecting data for research studies. It describes the types of qualitative and quantitative data and some common sources of primary and secondary data like clinical observations, questionnaires, and administrative databases. Some specific data collection methods are explained like personal interviews, self-administered questionnaires, use of medical records, observation, and physical or chemical measures. Criteria for selecting a data collection method include appropriateness, feasibility, cost, validity, reliability, and responsiveness. The document also covers creating a data collection sheet and entering data in an analyzable format with consideration of variable type and unit of analysis.
This document discusses data analysis and presentation. It covers qualitative and quantitative analysis methods, scales of measurement, tools to support analysis, and theoretical frameworks like grounded theory and activity theory. Graphs, stories, and summaries are presented as ways to communicate findings, which should be supported by the data and not overstate the evidence.
This document discusses data analysis, interpretation, and presentation. It covers analyzing both qualitative and quantitative data to describe, summarize, identify relationships, compare and forecast outcomes. The type of analysis depends on the scale of measurement - nominal, ordinal, or numerical. Qualitative analysis involves identifying patterns, categorizing data, and critical incidents. Findings can be presented visually through graphs or by using notations, stories, and summaries. The goal is to move from describing what is found in the data to explaining why.
1. Clinicians aim to build "digital twins" of cancer patients by simulating treatment options on virtual models using patient data and high-performance computing.
2. Digital twins could enable modeling personalized treatment benefits while incorporating various factors to predict individual health trajectories and outcomes.
3. Barriers include developing multiscale analytics to integrate data and models across scales per patient as well as establishing data platforms and commons to support this analysis.

This presentation tells about health education for hand wash to children. Every child should know that how to keep hand clean. And maintain the good hand washing practices. Nowadays disease are easily spread through uncleaned hands.germs are habitat in their hands and then it causes different types of diseases.so, we must give the health education for hand washing to every children. And make them practice.
George’s Place - an invite only hub to support stroke survivors: highlighting...Andrew Bateman
This poster was prepared for the World Federation of Neurological Rehabilitation, Special Interest Group in Neuropsychological Rehabilitation conference Summer 2024
I have been working with Body Activation and Leanna Luxton and fabulous University of Essex Students thinking about how prepare the next generation of therapists with appropriate digital skills

2 Body Activation Ltd a national community provider and training company working in partnership with Northamptonshire Community Stroke Team, Northampton General Hospital, Northampton, United Kingdom
Background and Objectives:
George’s Place is an invite only hub for stroke survivors facilitated by Body Activation Ltd. It is currently being piloted with the team and patients at NGH. The community provided has been co-constructed with patients to provide a timetable of live and asynchronous activities. It has a clear theoretical and philosophical approach to empowering stroke survivors, and it enables a safe space to share ideas, take part in yoga, art work, exercise, and conversations with clinicians, other survivors and – for the first time – trainee Allied Health Professionals.
Clinical placements for training health professionals traditionally involve face-to-face observation and involvement in therapy provided in various clinical settings. Involving students in the network has revealed the opportunity and need to develop new digital clinical skills.
Progress
In January 2024 at the University we hosted a new cohort of five students who took part in a placement that included time learning how to navigate the network. Students arranged interviews with participants as a way of building their clinical skills, and to gain exposure to people who could share the challenges of living with the consequences of stroke.
Results
Students enjoyed meeting stroke survivors who are keen to help the next generation of therapists develop their skills. They developed awareness of the need to co-construct resources. Students have considered the different needs of participants including those who choose to “just lurk”, the need for technical support for those having difficulty accessing the technology, and the potential benefits of membership of the network.
Conclusion
Clinical training needs to include opportunities to work with patients in social media spaces in addition to traditional training in face-to-face encounters. Online platforms that support life after acquired brain injury provide exciting possibilities to reduce isolation, improve accessibility of resources, and they provide important developmental opportunities for students and stroke survivors alike. The training needs for clinicians to be equipped to work in this social media era deserve elucidation.
PROGRAMMING OF HANAU WIDE VUE & GOTHIC ARCH TRACING.pptxSatvikaPrasad
Programming a Hanau articulator and performing Gothic arch tracing are essential steps in prosthodontics to ensure precise jaw movement replication and occlusal accuracy. The Hanau articulator, a semi-adjustable dental instrument, simulates mandibular movements by allowing customization based on the patient's unique jaw dynamics. This involves setting the condylar inclination, Bennett angle, and incisal guidance. Gothic arch tracing, on the other hand, is a technique used to record the centric relation of the mandible. It involves using a stylus and recording plate to trace mandibular movements, creating a characteristic arrow-point tracing that aids in accurately locating the centric relation. Both procedures are crucial for fabricating well-fitted dental prostheses, ensuring patient comfort, and maintaining optimal oral function.

The Simulacrum, a Synthetic Cancer Dataset
1. Supporting precise data
analysis without releasing
patient records: the Simulacrum
in action
Cong Chen, Paul Clarke, Lora Frayling, Sally Vernon, Brian Shand, Pesh
Doubleday, Jem Rashbass
2. Overview
• Context and goals of this talk
• Background: our motivating problem
• What is synthetic data and how does it help?
• What is the goal of the data exercise?
• Building a synthetic data model in the Simulacrum
• Results and applications
• Conclusion
Presentation title - edit in Header and Footer
3. TalkAims
• Introduce and motivate
concepts
• Synthetic data
• The information governance
environment
• Externally guided analysis
• Describe and explain
• The Simulacrum as synthetic data –
what is it and how was it created?
• Synthetic data-guided queries
• How this has led to faster, more
private answers
Presentation title - edit in Header and Footer
4. Problems with sharing cancer data
• Lots of data is available
• This would enable researchers and industry to provide
valuable insight into disease epidemiology, survival,
clinical practice, resource utilisation, outcomes
• Highly sensitive
• Sharing data is an exercise in risk-reward balancing
• Complex and intricate
• Data dictionaries do not provide a perfect view of what
to expect, analysis can be slow to converge
Presentation title - edit in Header and Footer
5. Synthetic data
• Data items which are not created by
observations
• This includes simulations (e.g.
Synthea), partially synthetic data
(generalised perturbation) and fully
synthetic data
• Does not represent individuals
• Removes re-identification risk, but
attribution risks remain

6. Simulacrum project aims
Users should have direct access to a public resource
• Showing data as it looks to internal analysts
• Be able to identify their cohort and the cohort size, data completeness and
quality, and the codes/ranges used
• Be able to prepare and code algorithms against the synthetic data
With a prepared analytical plan
• Engage PHE with the proposed study
• Share code which runs on the real data
• Be able to complete analysis without releasing row-level or other sensitive
data
Take a data-driven approach where possible
• Use parameters
• To adjust for differently sized or shaped datasets
• To adjust to different privacy constraints/requirements

7. Linked datasets
• Data represents the course of patient treatment – we are
interested in a coherent story and sensible timeline.
• Patients can have multiple tumours, with very many
treatment events – we need to capture this.
8. How did we do it?
• Key idea: sample from empirical conditional distributions.
• Question: how do we keep from running out of data?
• Use low-dimensional distributions.
• Question: which variables do we condition on?
• Use independence tests to find strongly associated
variables.
9. More details
• Question: what do we do for linked tables?
• Use all previous data (but in read-only mode).
• Question: what about sequences of events?
• Use information from the previous event (if it exists)
and data in upstream tables – so a Markov model.
• Question: what about sampling from small conditional
distributions, which risk reflecting real individuals?
• Cluster these distributions to meet accepted healthcare
data standards.
11. The Simulacrum as a dataset
• Version 1 – released 2018. 1.5 million tumours
(corresponding to English incidences 2013-2015) with
tumour/demographic/mortality data and chemotherapy
treatment.
• Representative at low dimensions (of variable
combinations), not as good for complex detail.
• Non-disclosive for public release.
• Ongoing development.

13. Applications
• Synthetic data used to back up a statistical query
gateway (currently manual).
• We’ve shared our synthetic data with partners to write
queries against – those have turned out to be robust and
aware of data formats, categories in our data and run
against our data.
• Publications accepted for conferences and journal
articles.
• We then try to release non-disclosive aggregates, model
parameters/diagnostics without the personal data used to
build those models.

14. Current work
• Better documentation of research and access process for
less technical researchers
• Model improvement, application in context of other
datasets
• More test-driven quality measures, automatic simulation
with specific goals
• Use other synthetic methodology within the data
architecture
• Fidelity isn’t objective – need to think about suitability for
specific purpose
15. Conclusions
• Synthetic data is a game changer for supporting
research and reducing risks
• This opens understanding of the data and analysis to a
wider audience while reducing workload and
misunderstandings
• Realistic understanding of aims and expectations helps
a synthetic data project improve mutual understanding
