Intra-abdominal pressure (IAP) is closely correlated with intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) diagnoses, indicating the need for continuous monitoring. Early intervention for IAH and ACS has been proven to reduce the rate of morbidity. However, the current IAP monitoring method is a tedious process with a long calibration time for a single time point measurement. Thus, there is the need for an efficient and continuous way of measuring IAP. Herein, a stretchable capacitive pressure sensor with controlled microstructures embedded into a cylindrical elastomeric mold, fabricated as a pressure sensing sleeve, is presented. The sensing sleeve can be readily deployed onto intrabody catheter balloons for pressure measurement at the site. The thin and highly conformable nature of the pressure sensing sleeve captures the pressure change without hindering the functionality of the foley catheter balloon.

Haptiknit: Distributed stiffness knitting for wearable haptics.
Sci Robot
December 2024
CHARM Laboratory, Stanford, CA, USA.
Haptic devices typically rely on rigid actuators and bulky power supply systems, limiting wearability. Soft materials improve comfort, but careful distribution of stiffness is required to ground actuation forces and enable load transfer to the skin. We present Haptiknit, an approach in which soft, wearable, knit textiles with embedded pneumatic actuators enable programmable haptic display.

Article Synopsis
- Colonoscopy has a failure rate of 3-5%, highlighting the need for ongoing training and skill development for both trainees and experienced endoscopists to enhance their performance and reduce complications.!* -
- A new hybrid colonoscopy training simulator combines physical and virtual elements to visualize pressure applied during procedures, providing quantitative feedback to improve skills among 33 study participants, including both trainees and experts.!* -
- Results show that trainees apply significantly higher pressure than experts, especially in the recto-sigmoid area, demonstrating the simulator's effectiveness as a learning tool, with participants agreeing on its usability and potential impact on training programs.!*
Food choices, microstructure of ingestive behavior and sensory perceptions after bariatric surgery in women: A cross-sectional study.

Unlabelled: Results regarding the impact of bariatric surgery (BS) on food choices are inconsistent between studies based on self-reported questionnaires, and those using direct measurements. Moreover, the determinants of the modifications of food choices after BS, if any, are still poorly understood. This study compared food choices, food liking, microstructure of ingestive behavior and sensory perceptions between women who had BS in the last 18 months (BS group, n = 19; Roux-en-Y gastric bypass or sleeve gastrectomy) and women with BMI ≥35 kg m (OB group, n = 17) in ecological conditions and explored the associations of food choices with sensory perceptions and food liking.

Article Synopsis
- A data-driven approach was developed to create digital twins for agricultural fields using a specialized Digital Soil Core (DSC) Probe equipped with seven different sensors, allowing for detailed soil analysis in real time at high vertical resolution.
- The DSC System integrates the probe, software, and equipment to scan soil characteristics up to 120 cm deep in about 60 seconds, producing a data cube that captures diverse soil conditions, unlike traditional methods that suffer from lower resolution and accuracy.
- The study conducted in California's almond orchards aimed to assess the discrepancies between high-res in situ sensor data and lower-res lab measurements to enhance soil prediction models, employing various statistical methods to analyze data integration techniques effectively.
Alterations in taste preferences one year following sleeve gastrectomy, Roux-en-Y gastric bypass, and one anastomosis gastric bypass: a cross-sectional study.

The influence of metabolic and bariatric surgery (MBS) on taste preferences and the pleasurable aspects of appetite may be mediated through its effects on gut hormones, potentially affecting weight loss results. Research indicates that the nature of the MBS performed significantly impacts food cravings in the year following the procedure, with no clear relationship to psychological factors or pre-surgery eating behaviors. During the period from August 2021 to August 2022, a group of adult patients with a body mass index (BMI) of 40 kg/m or above, or 35 kg/m or above with obesity-related medical complications, underwent Roux-en-Y gastric bypass (RYGB), one-anastomosis gastric bypass (OAGB), or sleeve gastrectomy (SG) at a tertiary academic center focused on MBS.
