Five chapters in Oncologic Critical Care
Five chapters on electrolyte disorders in oncologic critical care. Explore the first-edition and updated publisher records.
Contributions across editions
Five chapter topics connect the first edition (online in 2019; book ©2020) with updated 2026 entries. Each edition has its own authors and affiliations; the 2026 microscopIA affiliation is not applied retrospectively. These links show the publishing history, rather than ten distinct research projects.
Published microscopIA affiliation: Department of Health Systems Engineering and Global Health, microscopIA, Bogotá, Colombia.
A published Springer contribution on electrolyte disorders in critically ill patients with cancer. Each chapter is linked to its publisher record and shown here as scholarly output—not as a standalone clinical recommendation.

Scientific evidence
Research with a clear purpose.
Explore each study’s question, methods, findings, authors and source. Preprints and submitted manuscripts are identified separately from published research.
A selection of microscopIA research, not the complete portfolio. Some governed projects are not displayed because of nondisclosure agreements or information-protection measures before publication.

Curation and scientific governance →How to read the numbers
Clinical outcomes
A percentage describes a proportion in the stated group. A risk ratio compares two risks: 1 means equal risks and 2 means twice the risk in the specified comparison. Association alone does not establish causation.
Number needed to treat
The estimated number of people treated for one additional benefit over a specified period and comparator. It depends on baseline risk and uncertainty.
Methods source ↗Health economics
A quality-adjusted life-year (QALY) combines length and quality of life. Net monetary benefit values health gains at the stated threshold, then subtracts costs. A cost-effectiveness probability describes model uncertainty, not the probability that a patient improves.
Methods source ↗Comparisons and precision
Read group order, units, design and follow-up with each estimate. Consult the source for confidence intervals and limitations.

Prognostic Instruments in Obstetric Critical Care: A Systematic Review of Intended Use, Validation, Calibration, and Clinical Readiness
Submitted · Submitted at Critical Care Medicine
Principal investigators: Dr. Joseph L. Nates · Jorge Racedo
- Study design
- Systematic review
- Geography
- Evidence synthesis
A systematic review of 41 reports evaluating prognostic instruments in obstetric intensive or high-dependency care by intended use, target outcome, validation stage, discrimination, calibration, risk of bias and clinical readiness. Evidence supports risk stratification more strongly than transportable individual risk prediction; no universally transportable stand-alone instrument for high-stakes decisions is established.
