Neurally Adjusted Ventilatory Assist (NAVA) is an innovative ventilation mode that empowers patients to control both the timing and level of ventilatory support. By utilizing the electrical activity of the diaphragm (Edi) as the control signal, NAVA enables synchronized non-invasive ventilation (NIV-NAVA) even in the presence of leaks, while also providing continuous monitoring of the patient's respiratory pattern and drive. NIV-NAVA offers several advantages compared to conventional non-invasive ventilation, including enhanced patient-ventilator interaction and synchrony, reliable respiratory monitoring, and self-regulation of respiratory support. These features make NIV-NAVA theoretically ideal for providing effective and tailored non-invasive support to newborns with respiratory insufficiency. In clinical practice, NIV-NAVA has been successfully employed in neonates to prevent intubation, facilitate early extubation, and deliver nasal continuous positive airway pressure in a novel manner. Set up and management of NAVA has unique differences from conventional ventilation and an understanding of these is essential for successful NAVA ventilation. The efficacy of this approach in neonatal care is supported by numerous studies and clinical experiences with NIV-NAVA, demonstrating its potential to improve outcomes for infants with respiratory challenges.

Climate change poses a growing threat to human health, increasing exposure to extreme environmental conditions. Wearable biosensors provide real-time monitoring of physiological responses to heat stress, including cardiovascular strain, thermoregulatory disruptions, sleep disturbances, and biomarkers of heat-related illnesses. These devices also assess behavioural adaptations, such as reduced physical activity, offering insights into physiological resilience and susceptibility.

Background: Patients with synchronous colorectal cancer liver metastasis (CRLM) often face sub-optimal outcomes from systemic therapy or resection. This study investigates the prognostic value of the pre-treatment S-index, a reliable non-invasive marker for liver fibrosis, for outcomes in synchronous CRLM patients.
Methods: This study included two populations of patients with synchronous CRLM: one population undergoing resection and another population receiving systemic therapy for unresectable CRLM.

Accurate assessment of alcohol-induced physiological effects is critical for preventing overconsumption and ensuring safe activities such as driving. While breath alcohol concentration (BrAC) measurement is widely used due to its simplicity, it can be confounded by mouth alcohol effects and provides only momentary data. Building on our previously developed Synchro-thermography technique, which synchronizes infrared thermal imaging with heart rate variability to detect vascular-related skin temperature fluctuations, we applied it to monitor physiological changes induced by alcohol.

Chronic wounds, a critical global health challenge, necessitate advanced solutions to address limitations in current care, such as subjective assessments, uncontrolled drug delivery, and poor integration of diagnosis and treatment. This study introduces a "clinic-in-a-dressing" system that combines in situ pH monitoring with dual-responsive (pH/enzyme) drug delivery for chronic wound management. The system integrates hyaluronic acid (HA)-encapsulated vancomycin-loaded zeolitic imidazolate framework (HZV) nanoparticles and fluorescein isothiocyanate (FITC) into a nanofiber-reinforced hydrogel sponge.

Non-invasive imaging modalities that identify rupture-prone atherosclerotic plaques hold promise to improve patient risk stratification and advance early intervention strategies. Here, phase-changing peptide nanoemulsions are developed as theranostic contrast agents for synchronous ultrasound detection and therapy of at-risk atherosclerotic lesions. By targeting lipids within atherogenic foam cells, and exploiting characteristic features of vulnerable plaques, these nanoemulsions preferentially accumulate within lesions and are retained by intraplaque macrophages.
