Abstract

Humidity sensors are indispensable for various electronic systems and instrumentations. To develop a new humidity sensing mechanism is the key for the next generation of sensor technology. In this work, a novel flexible paper-based current humidity sensor is proposed. The developed alternating current electroluminescent devices (ACEL) consist of the electroless plating Ni on filter paper and silver nanowires (AgNWs) as the bottom and upper electrodes, and ZnS:Cu as the phosphor layer, respectively. The proposed humidity sensor is based on ACEL with the paper substrate and the ZnS:Cu phosphor layer as the humidity sensing element. The moisture effect on the optical properties of ACELs has been studied firstly. Then, the processing parameters of the paper-based ACELs such as electroless plated bottom electrode and spin-coated phosphor layer as a function of the humidity-sensitive characteristics are investigated. The sensing mechanism of the proposed sensor has been elucidated based on the Q ~ V analysis. The sensor exhibits an excellent linearity ( R 2 = 0.99965 ) within the humidity range from 20% to 90% relative humidity (RH) and shows excellent flexibility. We also demonstrate its potential application in postharvest preservation where the EL light is used for preservation and the humidity can be monitored simultaneously through the current.

Abstract

This study evaluates the effectiveness of combining oral polyethylene glycol electrolyte solution with hypertonic sugar saline enema for colonoscopy preparation in autistic children.Clinical data of 58 children with autism who underwent fecal bacteria transplantation and transendoscopic enteral tubing (TET) catheterization at the hospital were retrospectively analyzed. Participants were allocated into 2 groups: a control group (26 children) and an observation group (32 children), differentiated by their intestinal preparation protocols. The control group was administered oral polyethylene glycol combined with normal saline enema, whereas the observation group was given oral polyethylene glycol combined with hypertonic sugar saline enema. The Boston Bowel Preparation Scale (BBPS) was used to score intestinal cleanliness. Differences in intestinal cleanliness and colonoscopy duration between the 2 groups were compared.The group treated with hypertonic sugar saline enema exhibited significantly higher BBPS scores (6.78 ± 0.83) and an intestinal passage rate of 96.86%, which were statistically significant compared with the control group (P < 0.05). In addition, the colonoscopy duration was notably shorter in the observation group (14.03 ± 4.86 minutes) compared with the control group (P < 0.05)Our findings suggest that an oral polyethylene glycol electrolyte solution combined with a hypertonic sugar saline enema is a more effective preparation method for colonoscopy in autistic children.

Abstract

Introduction and Importance: Extranodal marginal zone lymphoma (EMZL lymphoma), also known as mucosa-associated lymphoid tissue (MALT) lymphoma, is a rare B-cell lymphoma that rarely affects children. The involvement of infectious agents, especially H. pylori , has been observed in the formation and progression of MALT lymphoma in the stomach. Hematemesis as the primary clinical manifestation is uncommon, highlighting the need for case studies with this presentation. This article uses SCARE2023 criteria as a framework to sort out a case report in order., Case Presentation: A 13-year-old female patient was admitted in August 2022 with an episode of hematemesis. She had a prior diagnosis of anaemia and was found positive for H. pylori . Despite treatment, she developed symptoms of chronic non-atrophic gastritis and had recurring episodes of hematemesis. Physical and diagnostic examinations revealed B-cell lymphoma localized in the gastric antrum. The primary diagnosis was extranodal MALT lymphoma with unique plasma cell differentiation., Clinical Discussion: The presentation of gastric MALT lymphoma can be variable, with definitive diagnosis often achieved via endoscopic biopsy. H. pylori plays a significant role in the onset and progression of this lymphoma, emphasizing the importance of its eradication for treatment. Effective outcomes can be achieved through anti- H. pylori treatment, although it is essential for clinicians to ensure its complete eradication post-treatment., Conclusion: Paediatric presentation of gastric MALT lymphoma, especially with hematemesis as the primary symptom, is rare and can be easily misdiagnosed. Compared to adults, children generally exhibit a better prognosis with effective H. pylori treatment. It is vital for medical professionals to recognize the differences in presentation between children and adults to ensure accurate diagnosis and treatment., Competing Interests: The authors declare that they have no conflicts of interest. The work has been reported in line with the SCARE criteria.Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article., (Copyright © 2024 The Author(s).
