Ultra high frequency (UHF) passive radio frequency identification (RFID) tag-based sensors are proposed for intravenous (IV) fluid level monitoring in medical Internet of Things (IoT) applications. Two versions of the sensor are proposed: a binary sensor (i.e., full vs. empty state sensing) and a real-time (., continuous level) sensor. The operating principle is demonstrated using full-wave electromagnetic simulation at 910 MHz and validated with experimental results. Generalized Additive Model (GAM) and random forest algorithms are employed for each interrogation dataset. Real-time sensing is accomplished with small deviations across the models. A minimum of 72% and a maximum of 97% of cases are within a 20% error for the GAM model and 62% to 98% for the random forest model. The proposed sensor is battery-free, lightweight, low-cost, and highly reliable. The read range of the proposed sensor is 4.6 m.

Although intraoperative magnesium sulphate administration has various advantages, its influence on the occurrence of postoperative acute kidney injury (AKI) remains unclear, particularly in patients undergoing robot-assisted radical prostatectomy (RARP). The steep Trendelenburg position and a high intra-abdominal pressure can render patients susceptible to AKI after surgery. This study aimed to evaluate the effects of intraoperative magnesium sulphate administration on postoperative AKI in patients who underwent RARP.

Background: Microcirculation is the essential link between macrocirculation and cellular metabolism.
Objectives: To test our hypotheses that microcirculation variables will show a heterogeneous flow pattern during experimental endotoxaemia, and that fluid therapy and noradrenaline (NA) infusion will normalise altered microcirculation variables.

Minimally invasive medical treatments for peripheral nerve stimulation are critically needed to minimize surgical risks, enhance the precision of therapeutic interventions, and reduce patient recovery time. Magnetoelectric nanoparticles (MENPs), known for their unique ability to respond to both magnetic and electric fields, offer promising potential for precision medicine due to their dual tunable functionality. In this study a multi-physics modeling of the MENPs was performed, assessing their capability to be targeted through external magnetic fields and become electrically activated.

Background: Reports of autoimmune diseases coexisting with autoimmune pulmonary alveolar proteinosis (autoimmune PAP; APAP) are extremely rare. APAP coexisting with autoimmune diseases may often be misdiagnosed as connective tissue disease-associated interstitial lung disease (ILD). Here, we describe a rare case of a patient with systemic sclerosis who was diagnosed with APAP after the exacerbation of lung opacities during treatment with immunosuppressive agents.
