The present paper focuses on electrical impedance scanning. The basic science behind the new modality, measurements of breast tissue impedance in vivo and in vitro, and the studies performed with a newly available commercial machine are discussed. Electrical impedance scanning has been generating interest for several reasons, including comfort to the patient, the relatively low cost, and studies suggest that it may be effective in detecting disease in mammographically dense breasts.

Background: Implantable cardioverter-defibrillators (ICDs) are essential for reducing sudden cardiac death in patients at risk of ventricular arrhythmias. The choice of ICD lead - single-coil or dual-coil - can influence device performance and patient outcomes. This meta-analysis evaluates the comparative efficacy and safety of single-coil versus dual-coil ICD leads to inform clinical decision-making.

Carcinoembryonic antigen (CEA) and C-reactive protein (CRP) are biomacromolecules known as cancer and inflammatory markers. Thus, they play a crucial role in early cancer diagnosis, post-treatment recurrence detection, and tumor risk assessment. This paper describes the development of an ultrasensitive and selective imprinted paper-based analytical device (PAD) as impedance sensor for determination of CEA and CRP in serum samples for point-of-care testing (POCT).

Organic mixed ionic-electronic conductors (OMIECs) could revolutionize bioelectronics by enabling seamless integration with biological systems. This review explores their role in neural biomimicry and biointerfacing, with a focus on how backbone design, sidechain optimization, and antiambipolarity impact performance. Recent advances highlight OMIECs' biocompatibility and mechanical compliance, making them ideal for bioelectronic applications.

The scope of this study was to determine the diagnostic performance of ABSI for obesity and sarcopenic obesity, compared to the results of bioimpedance analysis (BIA) and BMI, by sex and age group. It involved a cross-sectional study with 12,793 participants in the second round of ELSA-Brasil (Longitudinal Study of Adult Health in Brazil), which obtained measurements of body fat percentage using BIA and anthropometry, verifying the performance of the diagnostic tests in order to compare the indices. The results showed that for obesity in men in all three age groups, the sensitivity was below 49%.

Scrub typhus is an infectious disease caused by Orientia tsutsugamushi. It is transmitted through bite of chigger mite larvae and presents with symptoms such as fever, myalgia, headache, rash, and a characteristic eschar at the site of mite bites. This report details the case of a woman exhibiting acute febrile illness, bilateral pneumonia, and severe hypoxemia, prompting suspicion of scrub typhus due to the presence of a typical eschar on the pubic mound.
