Wearable Kirigami‐Apertured Capacitive Sensors for Continuous Cardiac Volumetric Monitoring

Advanced Functional Materials, EarlyView.
A wearable kirigami‐apertured carbon nanotube‐paper composite (K‐CPC) capacitive sensor enables cardiac volumetric monitoring. The kirigami process creates a central aperture with cantilevered fibers that confine the electric field, enhancing both sensitivity and lateral resolution.

Hydrogel Microtube Drug Carrier for Catheter‐Based Intravascular Therapy

Advanced Healthcare Materials, EarlyView.
This paper proposes hydrogel microtube carriers composed of barium alginate gel, enabling long‐term vascular retention without interrupting blood flow. Intravascular treatments have long been attracting attention for therapeutic efficacy, yet practical delivery methods remained unestablished.

A Novel Drug‐Loaded Porous Parylene Electrode for Targeted Anti‐Inflammatory Therapy and Hearing Preservation in Cochlear Implantation

Advanced Healthcare Materials, EarlyView.
A porous parylene‐coated electrode loaded with dexamethasone was developed to reduce inflammation after cochlear implantation. In guinea pigs, the device provided sustained drug release, maintained biocompatibility, improved auditory brainstem response thresholds, and reduced inflammatory cell infiltration and TNF‐α expression.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Umbilical and Peripheral Venous Catheter-Related Outcomes in Premature Neonates

Children
Background: Central venous catheters are essential but associated with complications in premature infants. We compared the short-term outcomes of umbilical venous catheter (UVC) versus peripherally inserted central catheter (PICC) as the initial ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Use of Intermittent Bolus Erector Spinae Plane (ESP) Block for Analgesia in Open Cholecystectomy: A Case Report

Southern Clinics of Istanbul Eurasia, 2019
The ultrasound-guided erector spinae plane (ESP) block has been recently described for postoperative analgesia after various thoracic and abdominal surgeries, mostly laparoscopic. Some authors suggest that the ESP block has an effect on both visceral and

DISINFECTION OF CATHETERS. [PDF]

Journal of the American Medical Association, 1886
To the Editor of the Journal: Dear Sir: —Permit me in this day of "catheter fever" to offer to your readers my mode of disinfecting catheters. Dr. Alexander Skene says that when he cut into his catheters which had lain several days in a strong solution of carbolic acid, they still contained micrococci underneath the incrustation.

Shape Memory Polymer‐Based Flexible Pressure Sensor for Real‐Time Venous Thrombosis Monitoring

Advanced Materials Interfaces, EarlyView.
A shape‐memory tubular flexible pressure sensor with a 100‐mesh microstructured SMP‐PLA/MWCNTs sensing layer was developed for PICC‐mounted monitoring of thrombosis‐related pressure changes. The sensor combines high sensitivity (204 kPa−1), a fast response time (28 ms), and conformal catheter fixation and was validated by hydrostatic and ex vivo ...
