Running a paediatric ambulatory sleep service in a pandemic and beyond

xlomafota13 shared this article with you from Inoreader Running a paediatric ambulatory sleep service in a pandemic and beyond Via Clinical Otolaryngology Abstract OBJECTIVES In response COVID-19, re-establishing safe elective services was prioritised in the UK. We assess the impact on face-to-face hospital attendance, cost, and efficiency of implementing a virtual sleep clinic (intervention 1) to screen for children requiring level 3 ambulatory sleep studies using newly implemented ENT-UK guidelines for obstructive sleep apnoea (OSA) investigation (intervention 2). Objectives: (1) compare the proportion of children attending sleep clinic undertaking a sleep study before and after implementation of these interventions; (2) compare clinic cancellations and first-time success rates of sleep studies before and after intervention. DESIGN Retrospective analysis. SETTING District general hospital paediatric sleep clinic. PARTICIPANTS Children aged 3 months to 16 years referred to sleep clinic by ENT for investigation of OSA over the 3-months immediately following interventions (1 June 2020 – 1 September 2020) to the same period in the previous year (1 June 2019 – 1 September 2019). MAIN OUTCOME MEASURES Number of children attending sleep clinic; date of birth / age of children attending sleep clinic; of number of children undergoing sleep study; diagnostic outcomes; number of appointment cancellations; number of first-time sleep study failures. RESULTS Post-intervention, there was a significant reduction in the proportion of children undertaking ambulatory sleep studies, and non-significant reductions in appointment cancellations and in first-time sleep study failures. CONCLUSIONS The introduction of the virtual sleep clinic meant that only those children requiring a sleep study attended a face-to-face appointment, which led to reduced face-to-face attendance. There were also unintended cost-effectiveness and efficiency benefits, with potential longer-term learning implications for the wider sleep community and other diagnostic services.

Triazine-based porous organic polymers for reversible capture of iodine and utilization in antibacterial application

xlomafota13 shared this article with you from Inoreader Triazine-based porous organic polymers for reversible capture of iodine and utilization in antibacterial application Via radioactive iodine Sci Rep. 2022 Feb 16;12(1):2638. doi: 10.1038/s41598-022-06671-0. ABSTRACT The capture and safe storage of radioactive iodine (129I or 131I) are of a compelling significance in the generation of nuclear energy and waste storage. Because of their physiochemical properties, Porous Organic Polymers (POPs) are considered to be one of the most sought classes of materials for iodine capture and storage. Herein, we report on the preparation and characterization of tw o triazine-based, nitrogen-rich, porous organic polymers, NRPOP-1 (SABET = 519 m2 g-1) and NRPOP-2 (SABET = 456 m2 g-1), by reacting 1,3,5-triazine-2,4,6-triamine or 1,4-bis-(2,4-diamino-1,3,5-triazine)-benzene with thieno[2,3-b]thiophene-2,5-dicarboxaldehyde, respectively, and their use in the capture of volatile iodine. NRPOP-1 and NRPOP-2 showed a high adsorption capacity of iodine vapor with an uptake of up to 317 wt % at 80 °C and 1 bar and adequate recyclability. The NRPOPs were also capable of removing up to 87% of iodine from 300 mg L-1 iodine-cyclohexane solution. Furthermore, the iodine-loaded polymers, I2@NRPOP-1 and I2@NRPOP-2, displayed good antibacterial activity against Micrococcus luteus (ML), Escherichia coli (EC), and Pseudomonas aeruginosa (PSA). The synergic functionality of these novel polymers makes them promising materials to the environment and public health. PMID:35173259 | DOI:10.1038/s41598-022-06671-0 View on the web Inoreader.

Leveraging Molecular Assays to Aid Decision-making in Large Indeterminate Thyroid Nodules

xlomafota13 shared this article with you from Inoreader Leveraging Molecular Assays to Aid Decision-making in Large Indeterminate Thyroid Nodules Via JAMA Otolaryngology–Head & Neck Surgery Online First To the Editor We read with great interest the recently published article by Dublin et al in JAMA Otolaryngology–Head & Neck Surgery, where it was shown that for indeterminate nodules larger than 4 cm, the positive-predictive value of a genomic classifier test (ThyroSeq) was 50% and the negative predictive value (NPV) was 89%. These values were noted to be improved relative to the test's performance on smaller nodules. The authors point out that the 2015 American Thyroid Association guidelines suggest that total thyroidectomy may be preferred for indeterminate nodules that are large (>4 cm) to limit completion thyroidectomy and conclude from their analysis that thyroid lobectomy may be sufficient for genomic classifier-negative indeterminate nodules.

Laryngeal High-Speed Videoendoscopy with Laser Illumination: A Preliminary Report

xlomafota13 shared this article with you from Inoreader Laryngeal High-Speed Videoendoscopy with Laser Illumination: A Preliminary Report Via Polyps Otolaryngol Pol. 2021 Sep 7;75(6):1-10. doi: 10.5604/01.3001.0015.2575. ABSTRACT <br><b>Introduction:</b> Advances in computer image analysis have enabled the use of new functional imaging methods in the diagnosis of laryngeal diseases. Particularly interesting techniques of dynamic laryngeal imaging involve High Speed Videoendoscopy (HSV). This still-developed technique allows to overcome the limitations of laryngovideostroboscopy (LVS) and a more detailed analysis of the glottal function based on the image of the actual vibrations of the vocal folds. It also enables the determination of objective coefficients parameterizing phonatory vibrations of the vocal folds.</br> <br><b>Aim:</b> The aim of this pilot study was to evaluate the use of a high-speed videoendoscopy set with laser illumination for the diagnosis of glottic pathology in ENT practice.</br> <br><b>Material and methods: </b> The study included 40 patients who underwent LVS followed by HSV. The modern HSV examination kit - Advanced Larynx Imager System (ALIS), used for the first time in a clinical setting in Poland, is characterized by significantly improved, compared to the previously used high-speed cameras, operational parameters - a light head, the possibility of continuous lighting operation without excessive heating of the head tip, registration of the image in full color scale. Thanks to such modernization, the safety and course of the examination do not differ from laryngoscopy conducted with commonly used recorders. The device owes some of these improvements to a laser illuminator which was used for the first time as the main light source in a high-speed camera. In the study, two cases were selected to present the results of HSV and the analysis of the generated kymograms - a woman with no glottic pathology and a man with a polyp of the right vocal fold. In the first case, the HSV exa mination compared with the LVS revealed a discrete glottis functional disorder in the form of a tendency to hyperphonation. The patient with an organic lesion had a clearly visible irregularity of vocal fold vibrations, which also allowed to trace mucosal wave disturbances related to its reflection from the pathological structure of the glottis and the formation of a return wave, both on the fold affected by the lesion and, to a lesser extent, contralaterally. The glottic dysfunctions observed in the studied patients were confirmed in the generated kymograms and the graphs of the glottal width waveform (GWW), as well as in the parameters calculated on their basis, assessing the frequency and amplitude of phonatory vibrations.</br> <br><b>Conclusions:</b> The use of high-speed videoendoscopy allows for a much more accurate assessment of the phonatory function of the glottis than in laryngovideostroboscopy. The presented HSV system allows for obtaining high qua lity kinematic images of the larynx, color fidelity, and contrast. The use of this technology in laryngological practice enables precise structural and functional assessment of the glottis and detection of discrete phonation disorders that elude the techniques used so far.</br&gt.
