Medicine - Mathematics & History

'We now come to the input of mathematics into medical history, and to the related questions of arithmetic and quantification, ratio and proportion, geometrical argument and diagrams, and probability. Mathematics (consisting in arithmetic, geometry, astrology and music) had an established place in the quadrivium of the medieval arts course; its application to medicine is demonstrated in such textbooks as the Articella, which include treatises on weights and measures, and in studies of proportion and ratio such as those of the medieval Oxford calculators which Italian doctors among others caused to be revived at the beginning of our period. In the sixteenth century, it was a vigorously debated subject; there is a well-documented discussion of the certainty of mathematics, concerning its status in respect to the logical adequacy of its proofs, in which some natural philosophers and doctors (notably Cardano) take part. It will come therefore as no surprise that it was prescribed for doctors by most Renaissance pedagogical writers;  this prescription is often specifically linked to Galen's geometrical (axiomatic) method whose operations are the constitution of objects from elements, the comparison of existing objects and their reduction into their constitutive elements.

Associated with mathematics are diagrams, that is, abstract quantified spatial representations. There is a modern debate about the contribution of technical innovations in illustration in the Renaissance (most notably perspective) to the scientific revolution: this is only relevant here insofar as some participants in this debate argue for the importance of diagrammatic symbolisation of mental abstractions above those, like perspective, which are still representations of the real world, and see the former as a step on the path to full algebraic notation of geometry. Not all Renaissance thinkers were persuaded of their usefulness: Argenterio describes the diagrams of Manardo and Akakia reproduced below as 'vain and false tables and figures'; but I shall argue here that they were related to the uptake of doctors from the arts course insofar as well-known logical diagrams reproduced above (4.3:3) were adapted by them for their own purposes.' pp.171-172.

Maclean, Ian. 2002. Chapter 5, Beyond logic: geometry, proportion, quantity. In Logic, Signs, and Nature in the Renaissance: The Case of Learned Medicine. Cambridge/New York: Cambridge University Press.

Related to ongoing reading, Maclean provides two (among several) historical illustrations (with apologies for the quality) on pp.174-175, the first is from the Wellcome Collection:

Dubois, Jacques, 1478-1555 (Boe͏̈, Jacques, Bois, J. d., Boë, J., del, Boë, J., Del Boë, J., DelBoe͏̈, J., . . . Sylvius/de Bois). (1548). Methodus sex librorum galeni in differentiis et causis morborum et symptomatum in tabellas sex ordine suo conjecta paulo fusius ne brevitas obscura lectorem remoretur & fallat. de signis omnibus medicis, hoc est salubribus, insalubribus, & neutris, commentarius / ... per jacobum sylvium ..Paris: Retrieved from https://www.proquest.com/books/methodus-sex-librorum-galeni-differentiis-et/docview/2090356749/se-2

Jacobus Sylvius, 1539

Which Maclean then translates / interprets (p.174):

Maclean. Figure 5.1, p.174.

'Manardo goes further, and causes and symptoms adapts the square of contraries to represent not only all the possible combinations of temperaments (combinations of cold and hot and wet and dry are cleverly excluded) but also inserts a mediate point to represent the absolutely temperate body: see fig. 5.2.
This adaptation of the square of contraries (which has precedents in the medieval period) shows the appropriation for their own use by doctors of the logical instruments at their disposal.

As we have seen, it is a feature of medical thinking to take into account many circumstantiae or variables, and, over time, the numbers of variables taken into consideration increases.' p.174-175.

"Hey Jonesy: Where's the book?"

This prompt from yesterday is far from new. There are outlines for papers on W2tQ.

Seriously though, what would a book outline look like - now?

The introduction is probably already written, it just needs to be pulled-together. But, in truth it (desperately) needs a new perspective. The question of how to update the explanation - short of running a workshop? The model's original purposes 1-4 are a statement of fact. The intro figures that invariably show how the axes 'create' the model's care, or knowledge domains? What if...? Could we also present the inverse? That would be a new slant. Does the model still 'work'? 

Details aside, here is a quick outline:

Part 1

Introduction and Background 

1.1 Brian E. Hodges and Post-Registration Nurse Education

1.2 Peter Jones - Primed to mind-map

1.3 Web presence: Initial website 1998-2015 - Blog 'Welcome to the QUAD' 2006 ...

1.4 Brian's original lecture notes

1.5 Looking back and forward: Models of care for the 21st Century

1.6 Confessions: So, where is the new site / platform? 

Part 2

 The Four (Five) Care Domains 

2.1 Science

2.2 Interpersonal (& Intrapersonal)

2.3 Sociology

2.4 Political

2.5 Spiritual

Part 3

Hodges' model in Practice - Applications

3.1 Self care

3.2 Clinical

3.3 Social Care - Community 

3.4 Management

3.5 Informatics

3.6 Policy 

3.7 Education

3.8 Workforce: Local - Global 

Part 4

The Legacies (still) in Our Midst

4.1 Person-centredness

4.2 Integrated Care

4.3 Holistic Care

4.4 Parity of Esteem

4.5 The Theory-Practice Gap

4.6 Change - Transformation: When? Disease to Prevention

Part 5

It's Tomorrow Now

5.1 Health Promotion

5.2 Public (Mental) Health & Protection

5.3 Citizenship

5.5 Planetary Health

Part 6

Research

6.1 Hodges' model as a Research Tool

6.2 Climate change

6.3 Planetary Health

6.4 Beyond the Bio-Psycho-Social Model: The Political Domain

6.5 The Literacies 

6.6 InterDisciplinary, Multi- and Transdisciplinary

6.7 Hodges' model as a Mathematical Object?

Part 7

Philosophy
 
7.1 Revisiting the Original Purposes
 
7.2 AI - The Elephant in Mind
 
7.3 Value & Values  

...?

Much to add, revise ... 'Education as Part X'. Political and Literacy too - a specific part - and with AI (in every part!)?

STOP!!

OK. It's a minefield. Even a proposal is a 'non-trivial' task.

Who's writing this? Not me! Not all of it, and for me; not AI either.

It would be marvellous to be one of several editors: one day? 

Clearly, a great project for students and early career researchers and current practitioners. 

An inoculation to help new cohorts deal with the realities, ravages and rewards of 'care' in its entirety*. 

P.S. With the start of a title right there? PJ

Graphene just broke a fundamental law of physics

Graphene just broke a fundamental law of physics.

Its electrons just did something physicists thought was impossible. For nearly 200 years, metals have obeyed the Wiedemann-Franz law – the rule that electrical conductivity and thermal conductivity always rise and fall together. 

But in ultra-clean graphene, researchers at the Indian Institute of Science found the opposite. As electrical conductivity increased, thermal conductivity dropped, shattering a principle taught in every physics textbook. 

The key lies at the “Dirac point,” a strange electronic tipping point where graphene is neither a metal nor an insulator. Here, electrons stop behaving like individual particles. Instead, they flow collectively as a nearly perfect fluid – a state called a “Dirac fluid.” 

This discovery doesn’t just rewrite the rules for graphene. It provides a tabletop window into extreme physics usually reserved for black holes and high-energy colliders. Scientists say this behavior could help probe mysteries of quantum entanglement, black hole thermodynamics, and the very fabric of matter itself.

While I can't fully understand this paper (even the abstract!), I realise that it is taking what seems a long time^ for industry and business to understand and realise the potential of graphene in industrial and technological applications. 


Hopefully, applications will emerge, that are beneficial to all. Reducing energy use, improving efficiency, removing pollutants even more effectively, imcreasing the durability and hence lifetime of materials and products, and more.

Also, marvellous to see global collaboration at work, as science continues to asks questions.

^I could have written exploitation there, but could we put the collective and planetary first?

Call - Special issue: Learning from Multiple Data Sources for Decision Making in Health Care

The increasing availability of digital data, along with recent developments in Artificial Intelligence, especially in the Machine Learning and Deep Learning fields, led the scientific community to debate whether data alone is sufficient for decision making and scientific exploration. We focus the attention on the healthcare domain, where peculiar issues affect data: indeed, data are usually collected under heterogeneous conditions (i.e., different populations, regimes, and sampling methods), suffer missingness – very often not at random – and their use is strongly constrained by privacy issues. In such a complex setting, this special issue challenges computer scientists to contribute to the above debate by designing and developing innovative methodological approaches, for solving complex decision-making problems in health care, leveraging on observational data.

Topics of interest include, but are not limited to, the following with an emphasis on novel generalizable methods applied to the healthcare domain:

  • Causal discovery from multiple data sets.
  • Federated causal discovery.
  • Causal discovery from heterogeneous data sets.
  • Transportability of causal models and inference.
  • Neuro-symbolic approaches to learn from heterogeneous data sources.
  • Continual learning on streams from multiple data sources.
  • Computational intelligent strategies to support causal inference.
  • Edge computing for decision making in healthcare.
  • Integrative AI methodologies.
  • Distributed inference methods.
  • Continual Learning.
  • Knowledge Discovery and Integration.
  • Combination of deductive approaches with ML models.
  • Combination of ontologies and/or knowledge-bases with ML to support decision making.

Peer Review Process:

All submitted papers will undergo a rigorous peer-review process featuring at least two reviewers. All submissions should follow the guidelines for authors available at the Journal of Biomedical Informatics website (http://www.elsevier.com/locate/yjbin). JBI’s editorial policy outlined on that page will be strictly enforced by special issue reviewers.

Note that JBI emphasizes the publication of papers that introduce innovative and generalizable methods of interest to the informatics community. Specific applications can be described to motivate the methodology being introduced, but papers that focus solely on a specific application are not suitable. A few examples of papers focused on methods previously published in JBI include: Kyrimi, et al. [1], Huang, et al. [2], Kocbek et al. [3], Houston et al. [4], García Del Valle et al. [5], Graudenzi et al. [6] and Sims et al. [7].

In particular, the authors of [1] showed the relevance of causal models and expert knowledge to develop credible models, i.e., capable of achieving good predictive performances when transported from the study cohort to the target population. Furthermore, [2] tackles the relevant issue of partially overlapping variables when data are collected from multiple data sources. This problem is extremely relevant both in theoretical and practical terms for decision making in the healthcare sector.

The contribution provided in [3] stressed the importance of working in a multi-source context by demonstrating how the linking of different repositories can improve the overall understanding of patients' conditions. Similarly, in [4] the authors extended this concept by introducing a methodology to evaluate to audit the data quality of the sources exploited by healthcare information systems. Then, in [5] the multi-source concept is transferred within the multi-modal environment and the authors surveyed the importance of considering different modalities to obtain a better disease understanding.

The works in [6] and [7] focuses on the importance of data. In [6] a data integration framework is defined for characterizing the metabolic deregulations that distinguish cancer phenotypes, by projecting RNA-seq data onto metabolic networks without the need for metabolic measurements; in [7] a biomedical informatics method is introduced that uses multiple public health data sources to perform surveillance of methadone-related adverse drug events. Interestingly, even if patient data are not linked between different data sources, results show that the integration of multiple public data sources can capture more cases and provide more clinical details than individual data sources alone.

Key requirements for JBI ML papers in addition to presenting novel methods (not simply application of existing methods to a new healthcare domain) are as follows: 1) projects must have clinicians involved in research question/problem formulation, defining input data, and assessing the results. 2) An explanation (with clinicians) of how the proposed method would fit into the clinical workflow is expected. It must be translational to practice. 3) Data sets should preferably be collected from hospitals after the research question was formulated, thus avoiding the use of available data (MIMIC) to define a very wide research problem that could potentially be answered with available open datasets (as an example: detecting if someone has COVID from Chest X-Rays would not be acceptable, as the gold standard test is the laboratory test). 4) As for explainability, SHAP values and related diagrams would not be enough: the paper should clearly describe and explain how clinicians use the visualization to make decisions.

This Venn diagram is interesting in itself, but please reflect upon it across the 'range' of Hodges' model? What stands out to me is how corporations and health care still grapple with this question.

It appears they struggle to find the 'magic' - let alone multiply it.

The Unconscious Patient (Sense of Smell), dated at around 1624-25, is part of Rembrandt's series depicting the five senses. It shows a woman holding a handkerchief, presumably containing smelling salts, under the nose of a young man who has fainted after a surgeon has performed a blood-letting.

Boyer's model, Hodges' model, scholarship, future website and Drupal

Ack: This blog post draws on a brief but informative two page text by Marta Nibert, Educational Consultant for Occupational Therapy, University of Idaho.

Models abound of course (not only on catwalks where other career choices are displayed), but in nurse education and the sciences. The review of Curriculum Development In Nursing Education reminded me of Boyer's model of scholarship. I have maintained a link to this for many years, the book review prompted me to read more. Boyer is a gift for this scholar of Hodges' model and any others, a gift not just in that off-the-shelf sense, but in a constructive advisory sense.

The table below highlights Boyer's types of scholarship, purposes and measures of performance. The focus of Boyer's model is the quality of professorial activities, in the same way highly skilled and experiences nurses can be removed from the front-line, so to can specialist faculty be distanced from teaching.

Type of ScholarshipPurposeMeasures of Performance
DiscoveryBuild new knowledge through traditional research.• Publishing in peer-reviewed forums.
• Producing and/or performing creative work within established field.
• Creating infrastructure for future studies.
IntegrationInterpret the use of knowledge across disciplines.• Preparing a comprehensive literature review
• Writing a textbook for use in multiple disciplines.
• Collaborating with colleagues to design and deliver a core course.
ApplicationAid society and professions in addressing problems.• Serving industry or government as an external consultant.
• Assuming leadership roles in professional organizations.
• Advising student leaders, thereby fostering their professional growth.
TeachingStudy teaching models and practices to achieve optimal learning.• Advancing learning theory through classroom research.
• Developing and testing instructional materials
• Mentoring graduate students.
• Designing and implementing a program level assessment system.

What I will try to do here is briefly suggest how Boyer can inform consideration of scholarship in Hodges' model and a future website. This is not just a one-way dialogue I believe Hodges' model can also inform Boyer's model. For example according to Nibert, Boyer proposes using 'creativity contracts'. The creative utility of Hodges' model is surely demonstrated in the posts and archive on W2tQ spanning nursing, education and health care? Since the publication of Boyer's paper in 1997 it could be argued there are new forms of scholarship that cast light and shadows on traditional academia and forms of research. More specifically though we can take Boyer's measures of performance and apply them in turn to h2cm. Even though the purposes differ (I am neither quality faculty nor professor) the reflection is helpful:

DISCOVERY

Publishing in peer-reviewed forums.
  • There is a limited bibliography listed here on W2tQ.
Producing and/or performing creative work within established field.
  • The bibliography and website constitute a mixture of formal and rather ad-hoc creative works in nursing. Much more needs to be done.
Creating infrastructure for future studies.
  • As noted in the book review I am fascinated by this word infrastructure. I recognise the need for a 21st century home for Hodges' model; the limitations of a static website and the need to benefit from the stimulus and energy that a community of users would provide. Drupal is the future (for me), a means to provide an infrastructure out of which a community may grow and inform.
INTEGRATION

Preparing a comprehensive literature review.
  • Hodges' model deserves a comprehensive literature review, one that spans education, nursing, global health, informatics and cognitive science.
Writing a textbook for use in multiple disciplines.
  • 'Book' is an established content type within Drupal and this is a worthy objective, as Hodges' model is the ideal academic Swiss Army knife.
Collaborating with colleagues to design and deliver a core course.
  • This is so dependent upon infrastructure and it seems my actively engaging with academics in curricula design and course planning. Drupal is being adopted in education so the scope to engage from an external position is a possibility.

APPLICATION

Serving industry or government as an external consultant.
  • Is professorship a pre-requisite for consultancy work? No. Do we just leave this to the professors? No.
Assuming leadership roles in professional organizations.
  • Being in the North West of England, a full-time nurse and with many meetings down South this is a barrier to adopting such roles. For the future should there be any opportunities these must be tried - only that way can they be tested.
Advising student leaders, thereby fostering their professional growth.
  • As a mentor in clinical practice with the chance to develop local educational links there is scope here; and possibly others?
TEACHING

Advancing learning theory through classroom research.
  • As noted above it would be marvellous to be presented with the task of producing lesson plans to encourage research into Hodges' model.
Developing and testing instructional materials.
  • As far as the classroom is concerned this is very much a bullet point for the future. Using Drupal however a future site can incorporate some instructional materials.
Mentoring graduate students.
  • Ongoing, but would like to engage more in this - and whilst h2cm is on my agenda I do understand models represent a small part of student learning.
Designing and implementing a program level assessment system.
  • Another point for a future departure; how do you demonstrate competency in Hodges' model? There are means of assessment, which were applied in the 1980's, case studies, essays and discussion. ...
More to follow...
