Bioimpedance Spectroscopy measurements and Cole-Cole models are commonly used to characterize biological systems. Cole-Cole model parameters may be obtained by fitting the measured bioimpedance data into a semicircle. This work proposes an iterative method to approximate a bioimpedance dataset to a Cole-Cole model analysis using only three points. The performance of the proposed method was compared against similar methods reported in a recent publication; our proposal presents greater efficiency (87.5%) and lower mean error (0.022) than the compared methods. The main contribution of the proposed method is that its performance does not rely on the user's technical knowledge, neither does it on the instrument used to perform the measurements, while the compared methods do.Clinical Relevance- Our proposal is an efficient unsupervised iterative method to acquire the clinically-relevant parameters from a Cole-Cole analysis from a given bioimpedance spectroscopy dataset, eliminating the need for the user to have prior technical knowledge on bioimpedance, thus, furthering the use of bioimpedance technology in the clinical point-of-care.

Objective: To examine and evaluate guideline concordance of surgical treatment selection at a community-based health system. The AUA guidelines provide specific guidance regarding appropriate utilization of radical nephrectomy (RN) and partial nephrectomy (PN). However, nearly 40% of patients did not fit a guideline-specified scenario in a prior report.

Electronic address:
Background: The unclear chemical composition and mechanisms of action pose challenges for new drug development and quality control of traditional Chinese medicine (TCM) formulas. To address this, the concept of effective-component compatibility (ECC) was proposed to represent drug combination with equivalent efficacy to TCM formulas, along with clear composition and dosage. However, previous strategies for screening ECC have often overlooked the synergistic effects of its components.

Background: Increasing patient demand and clinician burnout in rheumatology practices have highlighted the need for more efficient models of care (MOC). Interprofessional collaboration is essential for improving patient outcomes and clinician satisfaction.
Local Problem: Our current MOC lacks standardization and formal integration of Nurse Practitioners (NPs) and Physician Assistants (PAs), resulting in reduced clinician satisfaction and limited patient access.
