AI Article Synopsis
- Urine leakage volume is a key indicator of incontinence severity, but few smart diapers currently monitor it continuously.
- The study developed two types of sensors—resistive and capacitive—integrated into traditional diapers to categorize urine leakage into mild, moderate, and severe.
- Results showed that the sensors could accurately monitor urine volume and frequency, with resistive sensors particularly effective, suggesting these innovations can better manage incontinence.
Article Abstract
Urine leakage volume is an important indicator reflecting the severity of incontinence in patients. Currently, there are limited smart diapers capable of continuous dynamic monitoring of urine volume. This study developed two types of urine volume sensors, resistive and capacitive, which were integrated with traditional diapers to assess urine leakage levels: mild leakage (0-5 mL), moderate leakage (6-12 mL), and severe leakage (above 12 mL). Three patterns of resistive urine volume sensors were designed, and the results showed that the A pattern could accurately determine urine volume and frequency levels. Additionally, three electrode spacing designs were tested for the capacitive urine volume sensors. The results indicated that the sensor with a 1 cm electrode spacing could determine the urine volume range, with each 1 mL increase in urine causing a capacitance rise of approximately 1.5-1.8 pF, with an error of about ± 0.5 mL per increment. Both resistive and capacitive methods showed high accuracy in monitoring urine volume and frequency. This study validated the feasibility of smart flexible fabric sensors in detecting urine volume and frequency, providing a potential solution for better assessing and managing the condition of incontinence patients.

Background And Aims: Glepaglutide is a long-acting GLP-2 analog developed to improve intestinal absorption in short bowel syndrome (SBS) patients. We conducted a trial to establish efficacy and safety of glepaglutide in reducing parenteral support (PS) needs in SBS patients with intestinal failure (IF).
Methods: In an international, placebo-controlled, randomized, parallel-group, double-blind, phase 3 trial, SBS-IF patients requiring PS ≥3 days/week were randomized 1:1:1 to 24 weeks of glepaglutide 10 mg twice-weekly (TW) or once-weekly (OW), or placebo.

High ambient heat can directly influence blood pressure (BP) through the vasodilation of the skin vasculature and indirectly by affecting urinary volume and electrolyte levels. We evaluated the direct and urine electrolyte-mediated effects of ambient temperature on BP. We pooled 5,624 person-visit data from a community-based stepped-wedge randomized control trial in southwest coastal Bangladesh from December 2016 to May 2017.

Objective: The current management for complex urethral strictures commonly uses open reconstruction with buccal mucosa urethroplasty. However, there are multiple situations whereby buccal mucosa is inadequate (pan-urethral stricture or prior buccal harvest) or inappropriate for utilization (heavy tobacco use or oral radiation). Multiple options exist for use as alternatives or adjuncts to buccal mucosa in complex urethral strictures (injectable antifibrotic agents, augmentation urethroplasty with skin flaps, lingual mucosa, bladder mucosa, colonic mucosa, and new developments in tissue engineering for urethral graft material) (1, 2).

This retrospective study evaluates the clinical efficacy of combined electroacupuncture and moxibustion for the treatment of neurogenic bladder in patients with spinal cord injury. Ninety patients with neurogenic bladder after spinal cord injury who were admitted to the hospital between January 2021 and August 2023 were included. The patients were divided into the study and control groups (n = 45 each) using a random number table method.

Background: Spinal cord injury (SCI) often leads to the loss of urinary sensation, making urination difficult. In a previous experiment involving six healthy participants, we measured heartbeat-induced acoustic pulse waves (HAPWs) at the mid-back, calculated time-series power spectra of heart rate gradients at three ultralow/very low frequencies, distinguished and formulated waveform characteristics (one characteristic for each power spectrum, nearly uniform across participants) at times of increased urine in the bladder and heightened urges to urinate, and developed an algorithm with five of these power spectra to identify when urination is needed by extracting the waveform portion (continuous timepoints) where all of the characteristics were consistent with the formulated characteristics. The objective of this study was to verify the validity of the algorithm fed with data from measured HAPW of participants with SCI and to adapt the algorithm for these individuals.
