Clinical predictors of internal carotid artery blowout in patients with radiated nasopharyngeal carcinoma

xlomafota13 shared this article with you from Inoreader Clinical predictors of internal carotid artery blowout in patients with radiated nasopharyngeal carcinoma Via Head & Neck Abstract Background The primary objective is to identify clinical predictors of internal carotid artery (ICA) blowout in radiated nasopharyngeal carcinoma (NPC). Methods Seventeen ICA blowouts, 14 external carotid artery (ECA) bleeds, and 60 controls were identified from January 1, 2007 to July 31, 2020. Multinomial logistic regression was performed to identify features predictive of ICA blowouts. Results Headache was significantly more common among ICA blowouts than ECA bleeds and controls (58.8% vs. 7.1% vs. 6.7%, p < 0.001). The petrous skull base and sphenoid sinus lateral wall was eroded in all petrous and cavernous segment blowouts, respectively. Nasoendoscopy showing exposed clivus (OR 20.5, 95%CI 1.3–324.2) and computed tomography demonstrating skull base erosion (OR 17.8, 95%CI 1.0–311.0) were significantly associated with ICA blowouts compared to controls. Conclusions Findings of headache and skull base erosion on nasoendoscopy or imaging during NPC surveillance warrants prophylactic intervention to avoid an ICA blowout. View on the web Inoreader.

The transcriptional characteristics of mast cells derived from skin tissue in type 2 diabetes patients at the single-cell level

xlomafota13 shared this article with you from Inoreader The transcriptional characteristics of mast cells derived from skin tissue in type 2 diabetes patients at the single-cell level Via histochem Acta Histochem. 2021 Sep 21;123(7):151789. doi: 10.1016/j.acthis.2021.151789. Online ahead of print. ABSTRACT OBJECTIVES: The mechanisms underlying the role of mast cells in wound healing have not been thoroughly studied, and even fewer data are available on studies related to mast cells in the skin of patients with type 2 diabetes mellitus (T2DM). Therefore, this study aims to explore the transcriptional characteristics of mast cells at the single-cell level in patients wit h T2DM and provide experimental data for studying mast cell behaviors under abnormal glucose metabolism. METHODS: Two patients with T2DM and one trauma patient without diabetes were enrolled. Samples were derived from skin tissue resected at the time of surgery and were isolated by single cell capture technology on BD platform to prepare single cell cDNA library. Seurat was used to process raw reads and analyze data downstream of single-cell RNA sequencing, including removal of low-quality cells, identification of cell clusters at the single-cell level, and screening for differential genes with fold change > 1.5 and p < 0.05 by two-sided t-test. We performed single-cell RNA sequencing on skin tissues of T2DM patients and non-diabetics and identified the cell cluster of skin, single-cell subsets, and transcriptional characteristics of mast cells at a single-cell level. Meanwhile, gene set enrichment(GSEA) analysis was performed on the differentially expressed genes. RESULTS: A total of 8888 cells were obtained from skin tissue. Clustering analysis revealed eight-cell clusters, identified as smooth muscle cells, dendritic cells, mast cells, and T cells, respectively. Cluster 6 was identified as mast cells with the marker genes TPSAB1, CPA3, TPSB2, MS4A2,KIT, etc., which accounting for 2.7% of the total cell number.Compared with the control group, the genes highly expressed in MCs from T2DM patients, include ADH1C, PAXIP1, HAS1, ARG1, etc., and the low expression genes include PHACTR2, GGA1, RASSF2, etc. GSEA analysis suggested that the signal pathways of MCS in T2DM patients included VEGF signaling pathway, Fc gamma R-mediated phagocytosis, the B cell receptor signaling pathway, natural killer cell-mediated cytotoxicity. CONCLUSIONS: The characteristic genes of MCs in the skin tissues of T2DM patients were described at the single-cell level. These genes and enriched signaling pathways provide a theoretical basis and data support for furth er researches on dermatopathy in patients with diabetes mellitus.

xlomafota13 shared this article with you from Inoreader Interest of the bc-GenExMiner web tool in oncology Via Association française pour l'étude du cancer Bull Cancer. 2021 Sep 21:S0007-4551(21)00299-X. doi: 10.1016/j.bulcan.2021.05.008. Online ahead of print. ABSTRACT We are taking advantage of the launch of the latest version (v4.6) of our web-based data mining tool "breast cancer gene-expression miner" (bc-GenExMiner) to take stock of its position within the oncology research landscape and to present an activity report ten years after its establishment (http://bcgenex.ico.unicancer.fr). bc-GenExMiner is an open-access, user-friendly tool for statistical mining on breast tumor transcriptomes, annotated with more than 20 clinicopathologic and molecular characteristics. The database comprises more than 16,000 patients from 64 cohorts - including TCGA, METABRIC and SCAN-B - for whom several thousands of genes have been quantified by microarrays or RNA-seq. Correlation, expression and prognostic analyses are available for targeted, exhaustive or customized explorations of queried genes. bc -GenExMiner facilitates the validation, investigation, and prioritization of discoveries and hypotheses on genes of interest. It allows users to analyse large databases, create data visualizations, and obtain robust statistical analysis, thereby accelerating biomarker discovery. Ten years after its launch, judging by the number of visits, analyses, and scientific citations of bc-GenExMiner, we conclude that this web resource serves its purpose in the international scientific community working in breast cancer research, with a never-ending rise in its use.

xlomafota13 shared this article with you from Inoreader Evaluation of retrootolithic function using galvanic vestibular-evoked myogenic potentials in patients with benign paroxysmal positional vertigo Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2021 Sep 25. doi: 10.1007/s00405-021-07094-9. Online ahead of print. ABSTRACT PURPOSE: The purpose is to investigate possible vestibulopathy in patients with benign paroxysmal positional vertigo (BPPV), inner ear tests, including cervical and ocular vestibular-evoked myogenic potentials (cVEMPs and oVEMPs) via various stimulation modes, were adopted. METHODS: Fifty BPPV patients were enrolled in this study. All patients underwent pure tone audiometry, cVEMPs, oVEMPs, and caloric tests. The recurrence status, abnormal rates of inner ear tests, and the characteristic parameters of VEMPs, such as wave latencies and amplitudes, were analyzed. RESULTS: In affected ears, the abnormal rates of acoustic cVEMPs, vibratory oVEMPs, galvanic cVEMPs, and galvanic oVEMPs were 62%, 28%, 36%, and 14%, respectively. The abnormalities of acoustic cVEMPs were significantly larger than those of vibratory oVEMPs, and acoustic/vibratory VEMPs had significantly higher abnormal rates than the corresponding galvanic VEMPs. CONCLUSION: BPPV patients may have both otolithic and neural dysfunctions. Otolithic organ damage occurs more frequently than retrootolithic neural degeneration, and the saccular macula might have a greater extent of damage than the utricular macula.

Up‐front neck dissection followed by chemoradiotherapy for T1–T3 hypopharyngeal cancer with advanced nodal involvement

xlomafota13 shared this article with you from Inoreader Up‐front neck dissection followed by chemoradiotherapy for T1–T3 hypopharyngeal cancer with advanced nodal involvement Via Head & Neck Abstract Background The advantage of up-front neck dissection (UFND) followed by chemoradiotherapy (CRT) for hypopharyngeal cancer (HPC) with advanced neck involvement remains controversial. We aimed to determine the indications. Methods The data of 41 and 14 patients with stage IVA/B (T1–T3 and ≥N2a) HPC who underwent UFND followed by CRT and received CRT, respectively, were retrospectively analyzed and compared. Results The 5-year overall survival (OS) and disease-specific survival rates for the UFND and CRT groups were 61% and 52% (p = 0.1019), and 89% and 74% (p = 0.2333), respectively. Moreover, patients aged ≥70 years or those with a pulmonary disease history had a significantly poorer prognosis due to aspiration pneumonia in the UFND group. The 5-year regional control (RC) for the UFND and CRT groups were 92% and 57%, respectively (p = 0.0001). Conclusions UFND followed by CRT was feasible with satisfactory RC. To further improve OS, aspiration pneumonia prevention is essential. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Orocutaneous Fistula After Oral Cavity Resection and Reconstruction: Systematic Review and Meta-Analysis

xlomafota13 shared this article with you from Inoreader Orocutaneous Fistula After Oral Cavity Resection and Reconstruction: Systematic Review and Meta-Analysis Via otol rhinol Ann Otol Rhinol Laryngol. 2021 Sep 23:34894211047463. doi: 10.1177/00034894211047463. Online ahead of print. ABSTRACT OBJECTIVE: Orocutaneous fistula (OCF) after reconstruction for oral cavity resection can lead to prolonged hospitalization and adjuvant treatment delay. Few studies have examined factors leading to OCF after oral cavity resection. Primary objective: evaluate overall incidence and factors associated with OCF after oral cavity reconstruction. DATA SOURCES : Scopus 1960-database was searched for terms: "orocutaneous fistula," "oro cutaneous fistula," "oral cutaneous fistula," "orocervical fistula," "oral cavity salivary fistula." REVIEW METHODS: English language studies with >5 patients undergoing reconstruction after oral cavity cancer resection were included. About 1057 records initially screened; 214 full texts assessed; 78 full-texts included. PRISMA guidelines were followed, and MINORS criteria used to assess risk of bias. Data were pooled using random-effects model. Primary outcome was OCF incidence. Meta-analysis to determine the effect of preoperative radiation on OCF conducted on 12 eligible studies. Pre-collection hypothesis was that prior radiation therapy is associated with increased OCF incidence. Post-collection analyses: free versus pedicled flaps; mandible-sparing versus segmental mandibulectomy. RESULTS: Seventy-eight studies were included in meta-analysis of overall OCF incidence. Pooled effect size sh owed overall incidence of OCF to be 7.71% (95% CI, 6.28%-9.13%) among 5400 patients. Meta-analysis of preoperative radiation therapy on OCF showed a pooled odds ratio of 1.68 (95% CI, 0.93-3.06). OCF incidence was similar between patients undergoing free versus pedicled reconstruction, or segmental mandibulectomy versus mandible-sparing resection. CONCLUSION: Orocutaneous fistula after oral cavity resection has significant incidence and clinical impact. Risk of OCF persists despite advances in reconstructive options; there is a trend toward higher risk after prior radiation. PMID:34553635 | DOI:10.1177/000348942 11047463 View on the web Inoreader.

A contemporary narrative review to guide molecular epidemiology of oral submucous fibrosis

xlomafota13 shared this article with you from Inoreader A contemporary narrative review to guide molecular epidemiology of oral submucous fibrosis Via International Journal of Molecular Epidemiology and Genetics Int J Mol Epidemiol Genet. 2021 Aug 15;12(4):61-70. eCollection 2021. ABSTRACT Oral submucous Fibrosis (OSMF) is a chronic disease that mainly affects the upper part of the aerodigestive tract. Areca nut and betel quid chewing has been established as the most significant causative factor for this condition. While OSMF is a predominantly Asian disease, the migrant populations from the region have taken the disease across the globe. Additionally, areca nut is now easily accessible in flavors and aggressively marketed. Many research activities have been undertaken for decades to understand the etiopathogenesis and risk factors of OSMF. Although OSMF is a slowly progressing disease, it has the potential to transform to an oral malignancy. This article is an attempt to review the literature and provide an update on its prevalence, etiopthogenesis and its diagnosis. We also highlight certain clinical, histopathological and molecular features that aid in the diagnosis and prognostication of OSMF, highlighting the importance of identifying the possibly high risk OSMF that is prone to malignant transformation. Using this information, future directions can be developed to include treatmentof OSMF through a dynamic gene-specific approach. PMID:34552689 | PMC:PMC8449189 View on the web Inoreader.

The Expression and Regulation of Na+-K+-ATPase in Nasal Epithelial Cells of Chronic Rhinosinusitis with Nasal Polyps

xlomafota13 shared this article with you from Inoreader The Expression and Regulation of Na<sup>+</sup>-K<sup>+</sup>-ATPase in Nasal Epithelial Cells of Chronic Rhinosinusitis with Nasal Polyps Via O.R.L. Journal for oto-rhino-laryngology and its borderlands Objective: Na+-K+-ATPase (NKA) is essential in maintaining cell permeability, reserving potential energy, and preventing cellular edema. Nevertheless, how NKA expression is altered and regulated in chronic rhinosinusitis with nasal polyps (CRSwNPs) remain uncertain. Therefore, the present study aimed to explore the expression and regulation of NKA in CRSwNP. Methods: NKA immunolabeling was assessed by the immunohistochemistry method, NKA prote in levels were detected with the Western blotting method, and mRNA levels of NKA and aquaporin-5 (AQP5) were assayed by real-time PCR in nasal tissues from CRSwNP and control subjects. The co-localization of NKA with inflammatory cells was evaluated by immunofluorescence staining. In addition, human nasal epithelial cells (HNECs) were cultured and stimulated using various stimulators to evaluate the regulation of NKA. Results: We found significantly decreased NKA positive cells, NKA protein levels, and mRNA levels of NKA and AQP5 in nasal tissues from CRSwNP patients compared to control subjects, especially in eosinophilic CRSwNP. Furthermore, NKA mRNA levels in HNECs were downregulated by staphylococcal enterotoxin B (SEB), lipopolysaccharides (LPSs), inflammatory cytokine (IFN)-γ, IL-4, IL-13, and IL-1β. Conclusion: NKA and AQP5 expressions were decreased in CRSwNP. NKA in HNECs could be suppressed by SEB, LPS, IFN-γ, IL-4, IL-13, and IL-1β. Impairm ent of NKA may contribute to the genesis and development of CRSwNP via inducing AQP5 downregulation and edema. ORL View on the web Inoreader. Take back control of your news feed.

Menopause and its Effect on Voice

xlomafota13 shared this article with you from Inoreader Menopause and its Effect on Voice Via Otolaryngology Indian Abstract This study was designed to study the impact of menopause on voice quality. Cross-sectional Observational study with a total of 100 subjects. All subjects underwent biochemical analysis which included thyroid function tests, estrogen levels, progesterone levels and underwent voice analysis using the VAUGHMI voice analyser software. 50 postmenopausal females as cases and 50 premenopausal females as controls were taken for the study. The females were of the age group 35–55 yrs in order to remove age as confounding factor. The primary outcome measure was Total score, calculated based on harshness, hoarseness and breathiness. The postmenopausal females had a poorer voice quality than the premenopausal females (Total score 1.62 vs 2.48, p < 0.001). There was a significant difference between the fundamental frequency and pitch and perturbation in frequency of the postmenopausal females as compared to premenopausal females. The difference in the pertu rbation in the intensity of the voice was not significant. No linear correlation could be established between the voice quality and oestrogen or progesterone levels but the intergroup variation of the two parameters was significant. The premenopausal females have better voice quality than postmenopausal females. The relationship between hormonal level and voice quality couldn't be established. Further studies are required to assess the relation of hormone levels & voice quality with the possibility of exploring voice cosmesis. Level of Evidence Level 3. View on the web Inoreader.
