Clinical Features of Intraductal Papillary Mucinous Neoplasm-Related Pancreatic Carcinomas in Long-Term Surveillance.

An appropriate surveillance system must be established to efficiently identify cases of intraductal papillary mucinous neoplasm (IPMN)-related malignant transformation. We analyzed the initial clinical background that affects long-term prognosis and narrowed the population for whom continued evaluation is inevitable. We included 1645 patients with IPMN treated at our hospital since 2010.

Efficacy of Serum BDNF for the Evaluation of Depressive Neurological Symptoms in Patients with Refractory Ulcerative Colitis.

Numerous patients with ulcerative colitis (UC) become mentally unstable after experiencing a long-standing, physically painful life, and their long-term prognosis is poorer than that of those who are mentally stable. The current study aimed to evaluate serum biomarkers for predicting mental instability, which is challenging to objectively quantify. In total, 29 refractory UC patients newly treated with filgotinib underwent measurements of blood parameters associated with depression and a quantitative assessment of quality of life using the Inflammatory Bowel Disease Questionnaire (IBDQ) before and after treatment initiation with a 12-week interval.

Successful Treatment of an Esophago-Tracheobronchial Fistula Using Double Stenting to Correct Initial Stent Migration: A Case Report and Literature Review.

: Esophago-tracheobronchial fistula is a severe and often fatal complication in patients with advanced esophageal cancer, requiring prompt attention. The standard treatment involves the placement of a covered stent, which is relatively simple to perform and effectively seals the fistula. However, stent migration remains a common issue, highlighting the need for improved methods to prevent it.

Design Considerations and Fabrication Protocols of High-Performance Intrinsically Stretchable Transistors and Integrated Circuits.

Intrinsically stretchable electronics represent a significant advancement in wearable and implantable technologies, as they offer a unique advantage by maintaining intimate tissue contact while accommodating movements and size changes. This capability makes them exceptionally well-suited for applications in human-machine interfaces, wearables, and implantables, where seamless integration with the human body is essential. To realize this vision, it is important to develop soft integrated circuits for on-body signal processing and computing.

Fournier's Gangrene in the Course of Treatment of Advanced Hepatocellular Carcinoma with Molecular-targeted Therapy.

Lenvatinib is a molecular-targeted agent with proven efficacy against hepatocellular carcinoma (HCC). We herein report a case of lenvatinib-associated Fournier gangrene. A 66-year-old man with advanced HCC presented with a high fever 4 weeks after switching to lenvatinib.

Secondary Growth Hormone Deficiency That Developed into Cirrhosis after Several Years of Interrupted Growth Hormone Replacement Therapy.

This case report describes a patient who received hormone replacement therapy for secondary panhypopituitarism and subsequently developed diabetes. His physician decided to discontinue growth hormone (GH) replacement, which was previously deemed contraindicated. Following the diagnosis of fatty liver, the patient began to exhibit liver damage that progressed over the ensuing years, ultimately leading to cirrhosis.

High-speed and large-scale intrinsically stretchable integrated circuits.

Intrinsically stretchable electronics with skin-like mechanical properties have been identified as a promising platform for emerging applications ranging from continuous physiological monitoring to real-time analysis of health conditions, to closed-loop delivery of autonomous medical treatment. However, current technologies could only reach electrical performance at amorphous-silicon level (that is, charge-carrier mobility of about 1 cm V s), low integration scale (for example, 54 transistors per circuit) and limited functionalities. Here we report high-density, intrinsically stretchable transistors and integrated circuits with high driving ability, high operation speed and large-scale integration.

Spiral NeuroString: High-Density Soft Bioelectronic Fibers for Multimodal Sensing and Stimulation.

Bioelectronic fibers hold promise for both research and clinical applications due to their compactness, ease of implantation, and ability to incorporate various functionalities such as sensing and stimulation. However, existing devices suffer from bulkiness, rigidity, limited functionality, and low density of active components. These limitations stem from the difficulty to incorporate many components on one-dimensional (1D) fiber devices due to the incompatibility of conventional microfabrication methods (e.

Virtually transparent surgical instruments in endoscopic surgery with augmentation of obscured regions.

Purpose: We developed and evaluated a visual compensation system that allows surgeons to visualize obscured regions in real time, such that the surgical instrument appears virtually transparent.

Methods: The system consists of two endoscopes: a main endoscope to observe the surgical environment, and a supporting endoscope to render the region hidden from view by surgical instruments. The view captured by the supporting endoscope is transformed to simulate the view from the main endoscope, segmented to the shape of the hidden regions, and superimposed to the main endoscope image so that the surgical instruments look transparent.
