Objectives:
to build and validate software for the care of people with cardiovascular risk.
Methods:
a methodological study, applied to software development, anchored in a nursing theory and classification system, in three stages: 1) requirements engineering; 2) software architecture and coding; and 3) testing and content validity by 12 experts in computer science, with a Content Validity Ratio score.
Results:
called e-TEORISC, in software format, for nursing care for people with cardiovascular risk, online and offline, containing a database linked to the Nursing Process stages. Experts considered that the attributes of functional suitability, performance efficiency, reliability, maintainability, usability, safety and portability obtained desirable scores.
Conclusions:
e-TEORISC has evidence of validity to instrumentalize care for people at cardiovascular risk, with potential for technology transfer to the Brazilian Health System.

Objectives:
to map the nursing theories developed in stricto sensu graduate programs in nursing in Brazil.
Methods:
a bibliometric study, carried out on the Coordination for the Improvement of Higher Education Personnel Theses and Dissertations Portal in October 2023. The controlled descriptors “Nursing Theory” and “Nursing Models” and the uncontrolled descriptors “Theories” and “Middle-Range Theory” were used. Selected studies were cataloged for analysis, which was conducted by the study authors, who have a doctoral degree and expertise in research on nursing theories.
Results:
thirty-nine nursing theories were mapped, with a predominance of middle-range theories (79.5%), focusing on nursing diagnostic concepts and use of the theoretical-methodology strategy of theoretical-causal validity.
Conclusions:
the study identified nursing theories developed in Brazil, recognizing trends, development strategies, theorized objects of disciplinary interest and investments necessary for practical application in Brazilian contexts.

Objectives:
to develop a middle-range theory of the existential dimension of being-in-the-world of chronic kidney disease in the light of humanistic nursing theory.
Methods:
exploratory-descriptive, qualitative, Grounded Theory study, whose guiding question was: what theoretical relationships can be established between clinical practice carried out in the context of renal replacement therapies and the concepts of humanistic nursing theory? Data were collected through semi-structured interviews with nursing staff and chronic kidney disease patients.
Results:
a theory was developed that describes and explains the existential dimension of being-in-the-world of chronic kidney disease, identifying the qualitative evidence present in this context.
Final Considerations:
the theory contributes to clinical nursing practice qualification in nephrology, consolidating nursing as an art and science, because it arises from care practice and research, in addition to rescuing what differentiates it within the health disciplines, which is care par excellence.

Objective:
To construct a middle-range theory for the nursing diagnosis of Sedentary Lifestyle in young adults.
Methods:
A methodological study for the validation of a nursing diagnosis based on a Middle-Range Theory, carried out in six stages: definition of the approach; definition of theoretical-conceptual models; definition of main concepts; development of a pictorial scheme; construction of propositions; establishment of causal relationships and evidence for practice. The theory construction was operationalized through an integrative review and supported by Roy’s adaptation model.
Results:
Three essential attributes were identified; 10 antecedents; 7 clinical consequences; a pictogram, 9 propositions, and 11 causal relationships and evidence for practice.
Conclusion:
The middle-range theory for the nursing diagnosis of Sedentary Lifestyle in young adults was constructed, expanding the understanding of this phenomenon, to be applied in clinical practice by nurses.

Objectives:
to reflect on theoretical framework use in nursing research.
Methods:
a theoretical-reflexive study, based on concepts and constructs pertinent to using nursing theories and other sciences, considering issues of epistemology or philosophy of science.
Results:
we presented what it is and why to do nursing research and what a theoretical framework is and why to use it, in addition to some considerations regarding theoretical framework use in nursing research, essential for constructing disciplinary knowledge, which enables the materialization of researchers’ work and the presentation of propositions resulting from investigations in and for nursing as a discipline and science.
Final Considerations:
based on a reflection based on epistemological conceptions, it is possible to affirm that a theoretical framework is the core of researchers’ thinking, delimiting a problem to be investigated and, based on it, outlining methodological strategies to be followed, supporting nursing action and thinking as discipline and science.

Objectives:
to develop and evaluate a Middle-Range Theory for the nursing diagnosis “Disrupted Mother-Fetus Dyad Risk” in high-risk pregnancies.
Methods:
this methodological study was conducted in two stages: theory development and evaluation. Dorothea Orem’s General Nursing Model was used as the theoretical-conceptual foundation. Evaluation was conducted using the Delphi method with seven judges, and consensus was achieved when the Content Validity Index of the evaluated items was ≥ 0.80.
Results:
the theory identified 20 elements of the nursing diagnosis “Disrupted Mother-Fetus Dyad Risk” (10 risk factors, 4 at-risk populations, and 6 associated conditions), 14 propositions, and 1 pictogram. After two rounds of evaluation, the theory was considered consistent, with consensus reached for all items, each achieving a Content Validity Index ≥ 0.80.
Conclusions:
the Middle-Range Theory included biopsychosocial factors explaining the nursing phenomenon “Disrupted Mother-Fetus Dyad Risk,” which aids in nurses’ diagnostic reasoning.

Objectives:
to develop a Middle-Range Theory for the Risk for imbalanced blood pressure pattern among incarcerated women.
Methods:
theoretical development study to obtain the theoretical-causal validity of the Nursing Diagnosis Risk for unstable blood pressure. The Middle-Range Theory was developed according to six stages: establishment of the approach to developing the theory; definition of the conceptual models to be later analyzed; definition of the main conceptions; a pictorial diagram; propositions; causal relationships and evidence for practice.
Results:
two attributes and 20 antecedents related to imbalanced blood pressure were identified, a pictorial diagram was developed, and nine theoretical propositions were presented.
Conclusions:
the theory developed here favors the diagnostic reasoning of nurses and contributes to planning actions to promote the cardiovascular health of incarcerated women. A new proposition for the diagnosis of Risk for unstable blood pressure was also structured with a new title, definition, and etiological factors.

Objective:
To analyze the uncertainties experienced by nursing professionals who contracted COVID-19.
Methods:
This qualitative research was conducted with 20 nursing professionals who fell ill from COVID-19. Data collection was carried out through semi-structured interviews; the data were then organized using thematic analysis and discussed in the context of Merle Mishel’s Reconceptualized of Uncertainty in Illness Theory.
Results:
The antecedents of the disease had a strong influence on how nursing professionals who contracted COVID-19 perceived uncertainty. The media coverage of the increasing number of cases, the collapse of the healthcare system, and the high mortality rate contributed to associating the disease with fear and panic.
Final Considerations:
Viewing it from the perspective of the disease’s antecedents, the illness of a nursing professional from COVID-19 underscores that before being professionals, they are human beings just like anyone else, undergoing adversities and facing the possibilities associated with being ill.
