Online ahead of print. ABSTRACT Spatial integration during the brain's cognitive activity prompts changes in energy used by different neuroglial populations. Nevertheless, the organization of such integration in 3D -brain activity remains undescribed from a quantitative standpoint. In response, we applied a cross-correlation between brain activity and integrative models, which yielded a deeper understanding of information integration in functional brain mapping. We analyzed four datasets obtained via fundamentally different neuroimaging techniques (fMRI and PET) and found that models of spatial integration with an increasing input to each step of integration were significantly more correlated with brain activity than models with a constant input to each step of integration. In addition, marking the voxels with the maximal correlation, we found exceptionally high inter-subject consistency wi th the initial brain activity at the peaks. Our method demonstrated for the first time that the network of peaks of brain activity is organized strictly according to the models of spatial integration independent of neuroimaging techniques. The highest correlation with models integrating an increasing at each step input suggests that brain activity reflects a network of integrative processes where the results of integration in some neuroglial populations serve as an input to other neuroglial populations.

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.

Downward Trend in Resident Myringotomy and Tympanostomy Tube Experience

xlomafota13 shared this article with you from Inoreader Downward Trend in Resident Myringotomy and Tympanostomy Tube Experience Via otol rhinol Ann Otol Rhinol Laryngol. 2021 Sep 23:34894211047478. doi: 10.1177/00034894211047478. Online ahead of print. ABSTRACT INTRODUCTION/OBJECTIVE: Historically, myringotomy, and the insertion of tympanostomy tubes has served as one of the initial surgical training experiences for residents. Resident experience with this procedure since the introduction of pneumococcal conjugate vaccines has not been well described in the literature. The objective of this study was to identify tre nds in resident training experience with chronic otitis media-related surgeries, such as myringotomy and tympanostomy tube placement. While multiple factors influence resident experience, we hypothesize that resident experience has decreased since the introduction of the pneumococcal 13-valent conjugate vaccine (PCV13). METHODS AND MATERIALS: In a retrospective review of Accreditation Council for Graduate Medical Education (ACGME) National Data Reports, mean number of myringotomy and tympanostomy tube cases logged in the Resident Case Log System from 2006 to 2019 were collated and plotted against years to identify monotonic trends. Mann-Whitney U test was used to compare pre-PCV13 era and post-PCV13 era data. RESULTS: Since the introduction of PCV13, there is a national decreasing trend in the myringotomy and tympanostomy tube placement by otolaryngology residents (P = .001). CONCLUSIONS: Otologic surgeries are an important part of resident education and historically have served as one of the initial surgical training experiences for residents. There has been a significant reduction in the number of myringotomy and tympanostomy procedures performed by otolaryngology residents in the past decade. While multiple factors influence resident experience, it is possible that introduction of PCV13 has impacted resident exposure to myringotomy and tympanostomy tube placement. Resident proficiency with this procedure has likely not been affected by introduction of PCV13. Data should be reassessed in 5 years to determine if an impact of the PCV13 vaccine on resident training is evident. PMID:34553634 | DOI:10.1177/00034894211047478 View on the web Inoreader.

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.
