Assessment of body composition in health and disease using bioelectrical impedance analysis (bia) and dual energy x-ray absorptiometry (dxa): A critical overview [PDF]

, 2019
The measurement of body composition (BC) represents a valuable tool to assess nutritional status in health and disease. The most used methods to evaluate BC in the clinical practice are based on bicompartment models and measure, directly or indirectly ...

All‐Hydrogel‐Based Organic Electrochemical Transistors for Implantable Physiological Signal Monitoring

Advanced Science, EarlyView.
All‐hydrogel based n‐type depletion‐mode OECTs is developed using a semiconductor hydrogel formed via ionic‐liquid‐mediated phase separation, combining efficient ion‐electron transport, tissue‐like softness, and long‐term biocompatibility. The device can monitor EOG and ECG on human skin and record real‐time ECG subcutaneously in rats, providing a ...

Body fatness or anthropometry for assessment of unhealthy weight status? Comparison between methods in South African children and adolescents [PDF]

, 2013
A variety of methods are available for defining undernutrition (thinness/underweight/under-fat) and overnutrition (overweight/obesity/over-fat). The extent to which these definitions agree is unclear.

Multimodal Wearable Biosensing Meets Multidomain AI: A Pathway to Decentralized Healthcare

Advanced Science, EarlyView.
Multimodal biosensing meets multidomain AI. Wearable biosensors capture complementary biochemical and physiological signals, while cross‐device, population‐aware learning aligns noisy, heterogeneous streams. This Review distills key sensing modalities, fusion and calibration strategies, and privacy‐preserving deployment pathways that transform ...

Dual‐Strategy Design of Heterojunction‐Enhanced Piezoelectric Hydrogels for Periodontitis Treatment

Advanced Science, EarlyView.
This study developed a piezoelectric hydrogel integrating heterojunction enhancement and dual‐salt synergy, combining robust electrical performance with mechanical stability and bioactivity to better match the periodontal microenvironment. Under ultrasound activation, the hydrogel markedly promotes macrophage M2 polarization, thereby reducing the ...

Prognostic Value of Psoas Major Muscle Volume in Assessing Sarcopenia in Elderly Patients With Rectal Cancer

Annals of Gastroenterological Surgery, EarlyView.
This study investigates the prognostic utility of a novel volumetric indicator—psoas volume index (PVI)—for assessing sarcopenia in elderly rectal cancer patients. Sarcopenia classified by our proposed PVI cut‐off values was associated with poor nutritional and inflammatory status, and patients with low PVI showed significantly worse long‐term outcomes.
