AI Article Synopsis
- This study aimed to determine if aerosolized indocyanine green could help find air leaks in patients who had lung surgery.
- Among 61 patients, the standard test found 38 air leak points, while the indocyanine green test identified 55 sites, including 18 additional leaks not detected before.
- The new method had a detection rate of 98%, significantly higher than the conventional test's 75%, and no complications from the indocyanine green were reported.
Article Abstract
Background: This study investigated whether air leak sites resulting from pulmonary resection could be identified by the administration of aerosolized indocyanine green into the airway.
Methods: Sixty-one patients who underwent lung resection surgery (54 video-assisted thoracoscopic surgeries and 7 thoracotomies) during 2019 to 2021 were enrolled. An additional sealing test including indocyanine green administration and observation with a near-infrared camera was performed after the conventional sealing test. The results of the indocyanine sealing test were compared with those of the conventional sealing test and evaluated. The observation period set for evaluating adverse events was 1 month.
Results: The conventional sealing test detected 38 air leak points, of which 20 were caused by stapler-related pleural defects. The indocyanine green sealing test identified 55 indocyanine green fluorescent sites. Among these, 37 sites were matched with air leak points identified in the conventional sealing test, and 18 new sites were identified in the indocyanine green test. Reexamination of newly identified indocyanine green fluorescent sites with the conventional sealing test showed 13 air leak sites additionally. The detection rate of the conventional sealing test was 75% and that of the indocyanine green sealing test was 98% (P = .001). No complications attributable to the aerosolized indocyanine green were encountered.
Conclusions: The indocyanine green sealing test could identify air leak points overlooked by the conventional method. This procedure may be suitable in video-assisted surgery to improve surgical field visibility, and it allows prolonged observation of the lung in a collapsed state.

Background: The WHO malaria treatment guidelines recommend a total dose in the range of 3·5 to 7·0 mg/kg of primaquine to eliminate ( ) hypnozoites and prevent relapses. There are however indications that for tropical isolates, notably from Southeast Asia, the lower dose of 3·5 mg/kg is insufficient. Determining the most effective regimen to eliminate hypnozoites is needed to achieve elimination of this malaria parasite.

There are two major styles of maggot debridement dressings: (1) confinement dressings that form a cage around the wound, and (2) containment dressings that completely surround the maggots within a sealed porous bag. For producers and clinicians wanting to prepare containment dressings using readily available polyester bags, it is currently difficult to seal these bags without expensive high-temperature plastic welders. This study aimed to identify simple and affordable methods for sealing maggots within polyester net bags.

The development of new graphene-based materials necessitates the application of suitable material imaging techniques, especially for the identification of defects in the graphene structure and its continuity. For this purpose, it is natural to use one of the main properties of graphene-electrical conductivity. In this work, we prepare a 9 cm large-area monolayer graphene membrane on porous scaffolding sealed with either GO or rGO.

Background: High-dose-rate (HDR) brachytherapy using Iridium-192 as a radiation source is widely employed in cancer treatment to deliver concentrated radiation doses while minimizing normal tissue exposure. In this treatment, the precision with which the sealed radioisotope source is delivered significantly impacts clinical outcomes.
Purpose: This study aims to evaluate the feasibility of a new four-dimensional (4D) in vivo source tracking and treatment verification system for HDR brachytherapy using a patient-specific approach.

Aim: To compare the microleakage in class V cavities restored with Activa Bioactive Restorative, Activa Pronto, and nanohybrid composite.
Materials And Methods: Standardized class V cavity preparations (mesiodistal: 3 mm; occlusocervical: 2 mm; axial depth: 1 mm) were made on the buccal surface of 60 extracted intact maxillary premolar teeth. The preparations were divided into three experimental groups ( = 20) depending on the restorative material used.
