Abstract
Background
The impact of thyroid nodule size is less useful in children who have smaller thyroid volumes than in adults. We investigate using a novel thyroid tumor ratio measurement in children with thyroid cancer.

Methods
Patient and pathologic characteristics were investigated via Student's t-test in a univariate analysis for any correlation with the log-transformed tumor ratio, followed by a multivariate linear regression.

Results
Of 75 patients with malignancy and tumor ratio information, mean ratio decreased with increasing age (p = 0.04). Out of several clinical factors, patients with lymph node metastases and those treated with postoperative radioactive iodine had significantly higher mean tumor ratios on multivariate analysis (p = 0.04 for both factors).

Conclusions
Our study is the first to describe thyroid tumor volume in pediatric thyroid cancer and shows that increased tumor ratio was associated with indicators of more advanced disease such as lymph node metastases and use of radioactive iodine.

Abstract
Background
To assess the efficacy and safety of preoperative embolization (PE) in patients with carotid body tumor (CBTs).

Methods
In a single-center retrospective cohort study, 127 patients underwent surgical resection of CBTs from January 2003 to December 2019. One-to-one propensity score matching was conducted between patients with or without PE.

Results
Thirty-two (25.2%) patients received PE. After propensity score matching, no statistically significant differences were found in the baseline characteristics of 28 patients in each group. Compared with NPE group, operative time and estimated blood loss (EBL) were significantly reduced in the PE group. The incidence of stroke, perioperative complications, intraoperative blood transfusion, vascular reconstruction, hospital stay, tumor recurrence, and all-cause mortality were not different between the PE and NPE group.

Conclusions
Preoperative embolization was efficient and safe with a reduction of intraoperative blood loss and operative time during CBT resection.

Abstract
Background
People with head and neck cancer (HNC) have complex health care needs; however, limited evidence exists regarding the nature or patterns of service access and use. This study explored the post-discharge health care needs and experiences of individuals with HNC from metropolitan and rural areas.

Methods
Health care appointments and services accessed by people with HNC were collated for 6-month post-treatment. Data analysis of the whole cohort examined patterns of access while journey mapping integrated participants' experiences of recovery.

Results
The 6-month service access journey was mapped for 11 people. Rural participants attended a significantly greater number of appointments (p = 0.012), higher canceled/missed appointments (p = 0.013), and saw more professionals (p = 0.007). Rural participants reported higher stress and burden due to service access barriers and unmet needs.

Conclusions
Multiple challenges and inequities exist for rural people with HNC. Findings inform opportunities to enhance the post-treatment recovery of people with HNC in rural areas.

Columnar localization and laminar origin of cortical surface electrical potentials

xlomafota13 shared this article with you from Inoreader Columnar localization and laminar origin of cortical surface electrical potentials Via cortical auditory J Neurosci. 2022 Mar 23:JN-RM-1787-21. doi: 10.1523/JNEUROSCI.1787-21.2022. Online ahead of print. ABSTRACT Electrocorticography (ECoG) methodologically bridges basic neuroscience and understanding of human brains in health and disease. However, the localization of ECoG signals across the surface of the brain and the spatial distribution of their generating neuronal sources are poorly understood. To address this gap, we recorded from rat auditory cortex using customized μECoG, and simulated cortical surface electrical potentials with a full-scale, biophysically detailed cortical column model. Experimentally, μECoG-derived auditory representations were tonotopically organized and signals were anisotropically localized to ≤±200 μm, i.e., a single cortical column. Biophysical simulations reproduce experimental findings, and indicate that neurons in cortical layers V and VI contribute ∼85% of evoked high-gamma signal recorded at the surfa ce. Cell number and synchrony were the primary biophysical properties determining laminar contributions to evoked μECoG signals, while distance was only a minimal factor. Thus, evoked μECoG signals primarily originate from neurons in the infragranular layers of a single cortical column.Significance Statement:Electrocorticography (ECoG) methodologically bridges basic neuroscience and understanding of human brains in health and disease. However, the localization of ECoG signals across the surface of the brain and the spatial distribution of their generating neuronal sources are poorly understood. We investigated the localization and origins of sensory evoked ECoG responses. We experimentally found that ECoG responses were anisotropically localized to a cortical column. Biophysically detailed simulations revealed that neurons in layers V &VI were the primary sources of evoked ECoG responses. These results indicate that evoked ECoG high-gamma responses are primarily generat ed by the population spike rate of pyramidal neurons in layer V/VI of single cortical columns, and highlight the possibility of understanding how microscopic sources produce mesoscale signals.

Potential effects of lowering the threshold of statistical significance in the field of chronic rhinosinusitis - A meta-research on published randomized controlled trials over last decade

xlomafota13 shared this article with you from Inoreader Potential effects of lowering the threshold of statistical significance in the field of chronic rhinosinusitis - A meta-research on published randomized controlled trials over last decade Via Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial Braz J Otorhinolaryngol. 2021 Dec 4:S1808-8694(21)00196-8. doi: 10.1016/j.bjorl.2021.11.004. Online ahead of print. ABSTRACT OBJECTIVE: To evaluate the impact of change in p-value threshold from 0.05 to 0.005, on published Randomized Controlled Trials (RCTs) over the last ten years in the field of chronic rhinosinusitis. METHODS: A search of the PubMed database from 1st January 2011 to 31st December 2020 was conducted to include all RCTs that used p-value to determine the effects of an intervention. Data extracted included p-values, type of intervention, publishing journal with indexing, registration, funding, and multi- or single center status. The proportion of primary endpoints having p < 0.005 was determined first, followed by those with p > 0.005 but <0.05. Logistic regression analysis was used to determine if any trial characteristic was associated with reporting of significant p-values. RESULTS: In total, 16 8 primary endpoints were identified from 123 RCTs. On analysis, 80 had a p-value <0.05, i.e., statistically significant on conventional parameter. Out of these, 53.75% had a p-value <0.005, which would retain significance under the proposed threshold, and the remaining 46.25% to be reclassified as "suggestive". None of the trial characteristics were contributing to reporting of conventional or proposed p-values on logistic regression analysis. CONCLUSION: Lowering the p-value threshold would render 46.25% of a decade of published RCTs results (in the field of CRS) to be reclassified as merely "suggestive" and not significant. Trial characteristics were not found contributing to reporting of p-value <0.005 or even <0.05. LEVEL OF EVIDENCE: II. PMID:35331655 | DOI:10.1016/j.bjorl.2021.11.004 View on the web Inoreader.

xlomafota13 shared this article with you from Inoreader The Auditory Processing Domains Questionnaire (APDQ): Brazilian-Portuguese version Via Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial Braz J Otorhinolaryngol. 2022 Jan 4:S1808-8694(21)00213-5. doi: 10.1016/j.bjorl.2021.12.001. Online ahead of print. ABSTRACT OBJECTIVE: The present study aimed to determine the fidelity, reliability, and internal validity of the APDQ when translated from English to Brazilian-Portuguese language. METHODS: The first phase included the APDQ translation into Brazilian-Portuguese including forward translation, translation assessment and back-translation in a group of 10 students. The second phase involved establishing the internal consistency and reliability of the APDQ Brazilian-Portuguese version. Data was collected from 66 students without any risk factor for auditory processing disorder. Subjects were divided into a younger group (7-10 yrs) and an older group (11-17 yrs). RESULTS: All items showed appropriate quality in terms of translation. In determining internal consistency, Cronbach's alpha in subscales of auditory proce ssing, attention and language was found to be 0.93, 0.85 and 0.74, respectively. Intraclass Correlation Coefficient for total score was 0.95, ensuring a strong test-retest reliability. CONCLUSION: The Brazilian-Portuguese version of the APDQ has favorable translation quality, internal validity and reliability. It is now ready for continued study as a differential screening tool for 7- to 17-year-old Brazilian children with listening difficulties who are at risk for auditory processing disorder, attention deficits and language learning challenges.

Preclinical study of Shen Qi Li Xin formula in improving the development of chronic heart failure

xlomafota13 shared this article with you from Inoreader Preclinical study of Shen Qi Li Xin formula in improving the development of chronic heart failure Via Cellular and Molecular Biology Histol Histopathol. 2022 Mar 25:18454. doi: 10.14670/HH-18-454. Online ahead of print. ABSTRACT Chronic heart failure (CHF) is a common clinical heart disease. In recent years, traditional Chinese medicines have shown good outcomes in CHF treatment. We aimed to explore the therapeutic effect of Shen Qi Li Xin formula (SQLXF) in CHF. CHF rats were treated with SQLXF at the doses of 8.48, 16.96, and 33.92 g/kg/d once a day for 4 weeks by intragastric administration. The hemodynamic and cardiac function parameters of the rats were monitored by conduction echocardiography. In our results, SQLXF treatment at the doses of 16.96 and 33.92 g/kg/d significantly improved the haemodynamics and cardiac function of CHF rats by enhancing the levels of LVSP, +dp/dtmax, -dp/dtmax, LVEF and LVFS and reducing the levels of LVEDP, LVEDD and LVESD. SQLXF treatment at 16.96 and 33.92 g/kg/d also attenuated the damage of myocardial tissues in CHF rats. In a ddition, compared with normal rats, the number of pericytes was reduced in myocardial tissues of CHF rats. SQLXF treatment at the doses of 16.96 and 33.92 g/kg/d obviously increased the number of pericytes and proliferation of endothelial cells and promoted angiogenesis in myocardial tissues of CHF rats. In vitro, SQLXF impaired low-oxygen-induced inhibition of cell viability and promotion of apoptosis in primary pericytes. Importantly, SQLXF enhanced the adhesion ability of pericytes to endothelial cells. In conclusion, SQLXF improved myocardial injury in CHF rats by enhancing the interaction between pericytes and endothelial cells, suggesting that SQLXF may be a potential drug for CHF treatment.

Oral metastasis as the first indication of undiscovered malignancy at a distant site: A systematic review of 413 cases

xlomafota13 shared this article with you from Inoreader Oral metastasis as the first indication of undiscovered malignancy at a distant site: A systematic review of 413 cases Via Head & Neck Abstract This systematic review is the first to provide evidence regarding demographic, clinical, and imaging characteristics, as well as information related to survival, of patients with oral and maxillofacial metastases of occult primary tumors. Case reports, case series, and cross-sectional studies were included. Ten databases were searched. The risk of bias was assessed using the Joanna Briggs Institute appraisal tools. Overall, 353 articles (413 patients) were included. Statistically significant associations between survival and multiplicity of metastatic foci, and between each of the main primary sites and some features of the oral lesions were observed. Some clinical and imaging characteristics can help dentists in raising diagnostic suspicions and also in relating to plausible primary sites. Early diagnosis of oral and maxillofacial metastases can positively affect the survival rate when they are the only focus of dissemination, conferring an important role on the dentist.

Liposarcoma subtype recurrence and survival: A UK regional cohort study

xlomafota13 shared this article with you from Inoreader Liposarcoma subtype recurrence and survival: A UK regional cohort study Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2022 Feb 24:S1748-6815(22)00101-2. doi: 10.1016/j.bjps.2022.02.023. Online ahead of print. ABSTRACT BACKGROUND: Clinical outcome data in the United Kingdom, Europe, and the United States have yet to facilitate appropriately specific surveillance for liposarcoma histological subtypes, despite being one of the most common soft tissue sarcomas. Therefore, this study aims to demonstrate histologic-specific differences in liposarcoma recurrence, disease progression, and survival and discuss the implications. METHODS AND FINDINGS: This cohort study involves patients from a regional sarcoma service in the UK who have had a primary surgical excision of liposarcoma between October 2002 and September 2019. The median follow-up is five years. Confirmed histopathological diagnoses of liposarcoma (n = 193) are organised according to the World Health Organisation recognised subtypes: atypical lipomatous tumours ( ALT), myxoid, pleomorphic, and dedifferentiated liposarcomas. In addition, retroperitoneal variants (n = 34) are included to illustrate the broader spectrum of phenotypes. The primary outcomes were local recurrence, distant disease progression, and disease-specific death, and compared using Kaplan-Meier analyses and tumour variables using Cox proportional hazard analyses. All three primary outcomes significantly differed (P < 0.0001, n = 193). There were no metastases or disease-specific death in patients with ALT (n = 92) and no metastases of their retroperitoneal counterparts (n = 17). Amongst the metastasising cases of rarer subtypes, there were pulmonary spread of pleomorphic (8/9, n = 20), dedifferentiated (4/5, n = 18), and myxoid (2/3, n = 29) liposarcomas. CONCLUSION: An absence of metastases of ALT should be considered alongside global evidence. Surveillance protocols could better differentiate between these subtypes and, in doing so, save patients a considerable a mount of irradiation, time, fear, and anxiety.

Columellar strut grafts versus septal extension grafts during rhinoplasty for airway function, patient satisfaction and tip support

xlomafota13 shared this article with you from Inoreader Columellar strut grafts versus septal extension grafts during rhinoplasty for airway function, patient satisfaction and tip support Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2022 Feb 24:S1748-6815(22)00095-X. doi: 10.1016/j.bjps.2022.02.017. Online ahead of print. ABSTRACT IMPORTANCE: Different techniques exist to provide tip support in rhinoplasty. There is little evidence to provide a consensus on the most effective choice. OBJECTIVE: Evaluating columellar strut graft (CSG) and septal extension grafts (SEG) for their influence on airway function, patient satisfaction and tip support. DESIGN, SETTINGS AND PARTICIPANTS: A retrospective cohort study was undertaken on 165 adult patients who underwent open rhinoplasty with either a CSG or SEG, from February 2012 to August 2019 in a single tertiary facial-plastic practice in Sydney, Australia. Operations were for both cosmetic and functional indications, and both primary and revision cases were assessed. Airway testing and patient-reported outcomes (PROMs) were performed preoperatively and at least 6 months following the procedure. Photographic tip analysis was taken from approximately 4 and 12-month postoperative photographs. MAIN OUTCOMES AND MEASURES: Nasal peak inspiratory flow (NPIF) and total nasal airway resistance (NAR) were the primary airway functional outcomes. The primary PROMs analysed were a visual analogue scale (VAS) for nasal obstruction and 13-point Likert scale for global cosmesis, the Nose Outcome Symptom Evaluation (NOSE), and the nasal obstruction score. Tip support was determined by the nasolabial angle (NLA) and Simon's ratio as assessed by Rhinobase developed by Apaydin et al. on lateral Frankfort plane photographs. Data normalised as an improvement over preoperative baseline, accounting for individual variability. RESULTS: A total of 165 patients was assessed (35.2 ± 12.9 yrs, 72% female), 100 (61%) of which received SEG. There were similar nasal airway assessments between CSG and SEG groups, with ΔNPIF (20.0 ± 42.1 L/min v 19.9 ± 44.9 L/min, p = 0.983) and Δ "obstructed" NAR (-1.13 ± 1.90 v -1.02 ± 4.33 Pa/cm3/s, p = 0.849). Amongst PROMs, a greater cosmetic outcome was seen in the SEG group (7.20 ± 2.97 v 5.69 ± 3.45, p < 0.01) with all other assessments similar between CSG and SEG techniques. Photographic analysis of tip projection showed reduced NLA distortion in the SEG. CONCLUSION AND RELEVANCE: While greater patient-perceived cosmesis was seen in patients with a SEG, there were similar airflow and patient-reported nasal function between groups. Photographic analysis of tip projection showed SEG patients additionally benefited from less NLA distortion and greater tip maintenance.

The application of polyethylene glycol‐coated collagen patches in nasal surgery

xlomafota13 shared this article with you from Inoreader The application of polyethylene glycol‐coated collagen patches in nasal surgery Via Clinical Otolaryngology Abstract Nasal packing is a significant factor of postoperative morbidity that affects quality of recovery following nasal surgery. The polyethylene glycol-coated (PEG) collagen patch (Hemopatch®) is a synthetic hemostatic agent with a dual mechanism of action, but whether it can be applied in nasal surgery remains unexplored. The postoperative symptoms of thick nasal discharge, loss of smell, headache, postnasal discharge, ear fullness and lack of good night's sleep in patients with Hemopatch are minimal after surgery. The total nasal resistance at postoperative day 1 (0.224 Pa/cm3) is lower than the preoperative total nasal resistance (0.412 Pa/cm3), indicating that the nasal air flow increases after surgery in patients using Hemopatch at postoperative day 1. This is the first report to demonstrate that Hemopatch is an alternative nasal packing to reduce the postoperative morbidity after nasal surgery. View on the web Inoreader.
