Abstract
ABSTRACT
Aim. The aim of the present study was to examine the effect of early mobilization protocol on the strength of diaphragmatic muscle and other inspiratory muscles after open heart surgery.
Background. Early mobilization is recommended as a safe protocol after open heart surgery to decrease hospital stay and post-op respiratory complications; however, our knowledge about its effect on improving respiratory muscles strength is limited.
Methods. This is a randomized single-blinded clinical trial conducted on 80 consecutive patients who underwent coronary artery bypass surgery and/or valvular surgery that were randomly assigned to experimental group (postoperative early mobilization) and control group (routine physiotherapy). On the day before surgery and the day before leaving intensive care unit (ICU), two scores were measured for assessing diaphragmatic muscle strength: maximum inspiratory pressure (PI max) and Strength index (S index). Hemodynamic parameters were also measured and compared.
Findings. According to both PI max and S index, diaphragmatic muscle strength decreased from 77.28 to 59.53 cmH2O in patients after surgery, but the changes in the experimental group was less than the control group, which indicates a significant improvement in the strength of the diaphragm muscle in the experimental group (p≤0.0001). Hemodynamic changes after surgery (lower blood pressure and increased heart rate) occurred in both groups without any significant clinical effect.
Conclusion. Early mobilization after cardiac surgery has positive effect on the strength of diaphragmatic muscle and is also safe as shown to have no adverse effect on hemodynamic parameters.

Abstract
Abstract
Aim. The present study aimed to evaluate a causal model of health anxiety based on spirituality, with the mediating role of cognitive avoidance in Intensive Care Unit (ICU) nurses.
Background. Health anxiety is considered one of the major psychological challenges in clinical settings, particularly among ICU nurses, who face significant psychological and emotional pressures, which can have detrimental effects on their professional performance and personal well-being.
Method. This was a descriptive correlational study. The statistical population consisted of all male and female nurses working in ICUs in Tehran (District 3) during the spring and summer 2024. A sample of 267 nurses was selected via non-random quota sampling, and they completed the Health Anxiety Inventory, the Spirituality Questionnaire, and the Cognitive Avoidance Questionnaire. Data were analyzed using structural equation modeling (SEM) via AMOS 26 software.
Findings. The results indicated that the proposed model has a good fit with the data and accounts for 67 percent of the variance in health anxiety. In the structural model, the direct path from spirituality to health anxiety was negative and significant (â= - 0.655), while the path from cognitive avoidance to health anxiety was positive and significant (â= 0.569). Furthermore, spirituality had a significant indirect effect on health anxiety by reducing cognitive avoidance (â= - 0.288).
Conclusion. Spirituality and cognitive avoidance are key components in explaining health anxiety. These findings emphasize the importance of simultaneously considering internal spiritual resources and cognitive strategies in understanding the structure of health anxiety and provide a theoretical basis for designing psychological interventions to promote mental health among ICU nurses.
