Characteristics of Nasal Foreign Bodies and Equipment on Complications During Removal Procedures

alexandrossfakianakis shared this article with you from Inoreader Characteristics of Nasal Foreign Bodies and Equipment on Complications During Removal Procedures via The Laryngoscope This study aimed to clarify the equipment for the safe removal of nasal foreign bodies. Suction, paper clips, and cotton swabs were considered beneficial equipment for the safe removal of nasal foreign bodies because of minimizing complications and their high versatility. Objective The treatment of nasal foreign bodies involves safe and reliable removal. Few reports have investigated the relationship between equipment and the incidence of complications. Methods This retrospective study included 300 patients with nasal foreign bodies (average: 3.28 years, interquartile range: 2–4 years). Patients' background, characteristics of nasal foreign body, equipment to remove the nasal foreign body, and complications were obtained from medical records. Statistical analysis was performed using Pearson's chi-square test for associated factors and the incidence of epistaxis among the complications. Results Nasal foreign bodies were found and removed in 256 patients. Forceps, hooks, suction, modified paper clips, and cotton swabs were mainly used to remove the nasal foreign bodies. Epistaxis due to the removal procedure was observed in 26 patients. The occurrence of epistaxis differed depending on the equipment (p = 0.077) and was less frequent in suction and paper clips than in forceps (p < 0.05 and p = 0.077). Epistaxis was not observed when a cotton swab was used. Aspiration and septal perforation were not observed. A statistical relationship was not detected between the hardness of foreign bodies and the occurrence of epistaxis (p = 0.251). The incidence of epistaxis was higher in cases nasal foreign bodies remained for 1 day and over than in cases foreign bodies were removed within 1 day (p < 0.05). Conclusions This study revealed that suction, modified paper clips, and cotton swabs could be beneficial options for minimizing complications in the removal of nasal foreign bodies.

Peri‐implantitis: A bibliometric network analysis of top 100 most‐cited research articles

alexandrossfakianakis shared this article with you from Inoreader Peri‐implantitis: A bibliometric network analysis of top 100 most‐cited research articles via Clinical Implant Dentistry and Related Research Abstract Background Over the past decades, there has been an increase in research publications focusing on peri-implantitis. When facing limited healthcare resources, bibliometric analyses can guide researchers and funding parties toward areas where reallocation or more focus on research activity is warranted. The main objective of this study was to identify the trends of the top 100 cited articles on peri-implantitis research as the first study of its kind. Methods A Web of Science search, using the keywords "peri-implantitis or periimplantitis" was built to create a database of the most-cited articles. Articles were ranked by citation count and screened by two independent reviewers. The bibliometric characteristics of the studies were gathered and analyzed using several bibliometric software. Author collaborations, author clusters, and keyword co-occurrence network analyses were also performed. The correlation between the citation count and the age of each article was tested. Results The top 100 cited papers were published from 1994 to 2018 and the total citation counts ranged from 119 to 972 with 244.5 citations/paper on average. There was no correlation between the age of the articles and the citation count (p-value = 0.67). 21% of the studies consisted of prospective clinical studies. 35% of the papers focused on treatment and prevention of peri-implantitis while 65% concerned epidemiology. The top three most prolific countries were Sweden (n = 31), Germany (n = 15), and Switzerland (n = 13). We found 12 authors who had greater than five publications on the list. Also, the most published journal was Clinical Oral Implants Research. Conclusion This study provides insight into the characteristics and quality of the most highly cited peri-implantitis literature. This revealed a deficiency in terms of the number of studies on treatment strategies as well as a higher level of evidence studies among the most- impactful papers on peri-implantitis at the moment.

How accurate is computer-assisted mandible gunshot wound management by patient-specific distraction device? Preoperative planning versus postoperative outcomes

alexandrossfakianakis shared this article with you from Inoreader How accurate is computer-assisted mandible gunshot wound management by patient-specific distraction device? Preoperative planning versus postoperative outcomes via International Journal of Oral and Maxillofacial Surgery via MedWorm.com Gunshot wounds of the lower face are a challenge for the surgeon. Customized distraction osteogenesis (DO) is a well-established procedure for managing facial gunshot wounds. However, differences between the preoperative planning and postoperative outcomes are often noted. This multi-centre, retrospective study was performed to analyse the differences between the planning and outcomes for the lower third of the face, in patients undergoing the computer-assisted repair of mandible gunshot wounds using patient-specific distraction devices.

GBMdeconvoluteR accurately infers proportions of neoplastic and immune cell populations from bulk glioblastoma transcriptomics data

alexandrossfakianakis shared this article with you from Inoreader GBMdeconvoluteR accurately infers proportions of neoplastic and immune cell populations from bulk glioblastoma transcriptomics data via Neuro-Oncology Advance Access Abstract Background Characterising and quantifying cell types within glioblastoma (GBM) tumours at scale will facilitate a better understanding of the association between the cellular landscape and tumour phenotypes or clinical correlates. We aimed to develop a tool that deconvolutes immune and neoplastic cells within the GBM tumour microenvironment from bulk RNA sequencing data. Methods We developed an IDH wild-type (IDHwt) GBM-specific single immune cell reference consisting of B cells, T cells, NK cells, microglia, tumour associated macrophages, monocytes, mast and DC cells. We used this alongside an existing neoplastic single cell-type reference for astrocyte-like, oligodendrocyte- and neuronal-progenitor like and mesenchymal GBM cancer cells to create both marker and gene signature matrix-based deconvolution tools. We applied single-cell resolution imaging mass cytometry (IMC) to ten IDHwt GBM samples, five paired primary and recur rent tumours, to determine which deconvolution approach performed best. Results Marker based deconvolution using GBM tissue specific markers was most accurate for both immune cells and cancer cells, so we packaged this approach as GBMdeconvoluteR. We applied GBMdeconvoluteR to bulk GBM RNAseq data from The Cancer Genome Atlas and recapitulated recent findings from multi-omics single cell studies with regards associations between mesenchymal GBM cancer cells and both lymphoid and myeloid cells. Furthermore, we expanded upon this to show that these associations are stronger in patients with worse prognosis. Conclusions GBMdeconvoluteR accurately quantifies immune and neoplastic cell proportions in IDHwt GBM bulk RNA sequencing data and is accessible here: https : // gbmdeconvoluter.leeds.ac.uk View on Web

Vitamin D levels in the assessment of Crohn's disease activity and their relation to nutritional status and inflammation

alexandrossfakianakis shared this article with you from Inoreader Vitamin D levels in the assessment of Crohn's disease activity and their relation to nutritional status and inflammation via Journal of Human Nutrition and Dietetics Abstract Background Crohn's disease (CD) is frequently associated with malnutrition, inflammation, and a deficiency of vitamin D (VD) with the relationships between these symptoms being poorly defined. Vitamin D is a modulator of the immune system and is associated with the onset of CD and disease activity. The level of serum VD may have potential in the assessment of CD activity. This study aimed to evaluate the relationships between VD, nutritional status, and inflammation, and to identify more accurate VD thresholds. Methods The study included 76 outpatients with CD diagnosed between October 2018 and October 2020 and 76 healthy volunteers. Levels of serum 25(OH)D and nutritional indicators, as well as biochemical and disease activity assessments were conducted. Results Patients with CD and healthy participants were found to differ significantly in their 25(OH)D levels as well in levels of nutritional and inflammatory indicators. The optimal VD cut-off value was found to be 46.81 nmol/L for CD development and 35.32 nmol/L for disease activity. Levels of 25(OH)D were correlated with both nutritional status and inflammation. Conclusions The VD level is likely to be a useful additional tool in the evaluation of CD patients and predicting the disease activity and clinical response. The VD level may relate both to the nutritional status and levels of inflammation in CD patients, as well as disease progression. This article is protected by copyright. All rights reserved.

Impact of air pollutants on influenza−like illness outpatient visits under COVID−19 pandemic in the sub−center of Beijing, China

alexandrossfakianakis shared this article with you from Inoreader Impact of air pollutants on influenza−like illness outpatient visits under COVID−19 pandemic in the sub−center of Beijing, China via Journal of Medical Virology Abstract Objective This study aimed to explore the association between air pollutants and outpatient visits for influenza−like illnesses (ILI) under the coronavirus disease 2019 (COVID−19) stage in the sub−center of Beijing. Methods The data on ILI in the sub−center of Beijing from 1 January 2018 to 31 December 2020 were obtained from the Beijing Influenza Surveillance Network. A generalized additive Poisson model was applied to examine the associations between the concentrations of air pollutants and daily outpatient visits for ILI when controlling meteorological factors and temporal trend. Results A total of 171,943 ILI patients were included. In the pre−COVID−19 stage, an increased risk of ILI outpatient visits was associated to a high air quality index (AQI) and the high concentrations of particulate matter less than 2.5 (PM2.5), particulate matter 10 (PM10), sulphur dioxide (SO2), nitrogen dioxide (NO2), and carbon monoxide (CO), and a low concentration of ozone (O3) on lag0 day and lag1 day, while a higher increased risk of ILI outpatient visits was observed by the air pollutants in the COVID−19 stage on lag0 day. Except for PM10，the concentrations of other air pollutants on lag1 day were not significantly associated with an increased risk of ILI outpatient visits during the COVID−19 stage. Conclusion The findings that air pollutants had enhanced immediate effects and diminished lag-effects on the risk of ILI outpatient visits during the COVID−19 pandemic, which is important for the development of public health and environmental governance strategies.
