ABSTRACT Background: The purpose of this study was to evaluate the association between thyroid cancer and breast cancer. Methods: Data from the Korean National Health Insurance Service-Health Screening Cohort were collected from 2002 to 2013. In study I, 3949 thyroid cancer participants were 1:4 matched with 15,796 control I participants, and hazard ratios (HRs) with 95% confidence intervals (CIs) for breast cancer were evaluated using a stratified Cox proportional hazard model. In study II, 3308 breast cancer participants were 1:4 matched with 13,232 control II participants, and HRs with 95% CIs for thyroid cancer were assessed in the same way as in study I. In the subgroup analyses, associations were analyzed according to radioactive iodine (RAI) treatment and age (<60 years old and ≥60 years old). Results: The adjusted HR for breast cancer in the thyroid cancer group was 1.64 (95% CI = 1.13-2.39, p = 0.010). The adjusted HR for thyroid cancer in the breast cancer group was 1.91 (95% CI = 1.47-2.49, p < 0.001). In the subgroup analyses, the groups that were older and not treated with RAI treatment showed consistent results in study I, and the younger and older groups showed consistent results in study II. Conclusions: Based on this cohort study, breast and thyroid cancer have a reciprocal positive association. PMID:35207622 | DOI:10.3390/jpm12020133 View on the web Inoreader.

Precise fabrication of porous polymer frameworks using rigid polyisocyanides as building blocks: from structural regulation to efficient iodine capture

xlomafota13 shared this article with you from Inoreader Precise fabrication of porous polymer frameworks using rigid polyisocyanides as building blocks: from structural regulation to efficient iodine capture Via radioactive iodine Chem Sci. 2022 Jan 12;13(4):1111-1118. doi: 10.1039/d1sc05361b. eCollection 2022 Jan 26. ABSTRACT Porous materials have recently attracted much attention owing to their fascinating structures and broad applications. Moreover, exploring novel porous polymers affording the efficient capture of iodine is of significant interest. In contrast to the reported porous polymers fabricated with small molecular blocks, we herein report the preparation of porous polymer frameworks using rigid polyisocyanides as building blocks. First, tetrahedral four-arm star polyisocyanides with predictable molecular weight and low dispersity were synthesized; the chain-ends of the rigid polyisocyanide blocks were then crosslinked, yielding well-defined porous organic frameworks with a designed pore size and narrow distribution. Polymers of appropriate pore size were observed to efficiently capture radioactive iodine in both aqueous and vapor phases. More than 98% of iodine could be captured within 1 minute from a saturated aqueous solution (capacity of up to 3.2 g g-1), and an adsorption capacity of up to 574 wt% of iodine in vapor was measured within 4 hours. Moreover, the polymers could be recovered and recycled for iodine capture for at least six times, while maintaining high performance.

Molecular aetiology of ski-slope hearing loss and audiological course of cochlear implantees

xlomafota13 shared this article with you from Inoreader Molecular aetiology of ski-slope hearing loss and audiological course of cochlear implantees 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. 2022 Feb 25. doi: 10.1007/s00405-022-07317-7. Online ahead of print. ABSTRACT PURPOSE: A challenge for patients with ski-slope hearing loss is that hearing aids do not adequately amplify the mid-to-high frequencies necessary for speech perception and conversely, cochlear implant (CI) may damage low-frequency hearing. We aimed to describe the clinical profile of patients with ski-slope hearing loss, with a special focus on aetiology of such hearing loss and audiological course of low-frequency hearing after CI. METHODS: We recruited hearing-impaired patients who visited a tertiary referral centre and met the criteria for ski-slope hearing loss patients from 2015 to 2021. Genetic testing was performed in all ski-slope hearing loss patients unless refused. Baseline audiograms of patients who continued to use hearing aids or who finally underwent CIs were reviewed. As for CI patients, outcome and hearing pr eservation rate were rigorously analysed. RESULTS: Of 46 recruited patients with ski-slope hearing loss, 45 agreed to undergo genetic testing and causative variants were identified in 17 (37.8%) patients. The TMC1, MYO7A, and TMPRSS3 variants were the most common, while LRTOMT was newly identified as a causative gene. Twenty-five patients eventually received CI, while 13 continued to wear the hearing aid and 8 patients did not ever try hearing aids. CI in ski-slope hearing loss led to immediate and sufficient improvement of sentence recognition by as early as 3 months, however, the duration of hearing loss was inversely correlated with the sentence recognition score. The average hearing preservation rate (using the HEARRING classification) after CI was 53.0% (SD 30.0) and 45.6% (SD 31.1) at 1 year. Seventy-nine percent of implantees maintained functional low-frequency hearing (better than 85 dB at 250 and 500 Hz) eligible for electric-acoustic stimulation (EAS). A trend was fo und that patients with hair cell stereocilia-associated genetic variants may have a slightly better preservation, albeit with no statistical significance. CONCLUSION: Detection rate of a molecular genetic aetiology of ski-slope hearing loss appears to be lower than other type of hearing loss reported in the literature. Especially with short hearing loss duration, CI in ski-slope hearing loss leads to immediate and sufficient speech improvement, while preserving functional low-frequency hearing eligible for EAS as many as in 79%. A certain genetic aetiology might be associated with a trend towards better low-frequency hearing preservation. PMID:35212774 | DOI:10.1007/s00405-022-07317-7 View on the web Inoreader.

A nomogram based on tumor response to induction chemotherapy may predict survival in locoregionally advanced nasopharyngeal carcinoma

xlomafota13 shared this article with you from Inoreader A nomogram based on tumor response to induction chemotherapy may predict survival in locoregionally advanced nasopharyngeal carcinoma Via Head & Neck Abstract Background To evaluate the clinical significance of tumor response to induction chemotherapy (IC) in locoregionally advanced nasopharyngeal carcinoma (LANPC) patients and further to develop a nomogram for predicting survival prognosis. Methods A total of 498 patients with stage III-IVA NPC applying IC and concurrent chemotherapy were reviewed (training cohort, n = 376; validation cohort, n = 122). Results Tumor response was an independent predictor for clinical outcomes. The nomogram included age, N stage, pretreatment Epstein–Barr virus DNA, lymphocyte-to-monocyte ratio, and tumor response achieved an ideal C-index of 0.703 (95% CI 0.655–0.751) in the validation cohort for predicting overall survival (OS), which outperformed than that of the TNM system alone (C-index, 0.670, 95% CI: 0.622–0.718). In addition, the nomogram could successfully classified patients into different risk groups. Conclusions We established and validated a precise and convenient nomogram based on tumor response for predicting the OS of LANPC patients. View on the web Inoreader.

Possible Rehabilitation Procedures to Treat Sarcopenic Dysphagia

xlomafota13 shared this article with you from Inoreader Possible Rehabilitation Procedures to Treat Sarcopenic Dysphagia Via swallowing exercises Nutrients. 2022 Feb 12;14(4):778. doi: 10.3390/nu14040778. ABSTRACT Sarcopenic dysphagia requires the presence of both dysphagia and generalized sarcopenia. The causes of dysphagia, except for sarcopenia, are excluded. The treatment for sarcopenic dysphagia includes resistance training along with nutritional support; however, whether rehabilitation procedures are useful remains unclear. In this narrative review, we present possible rehabilitation procedures as a resistance training for managing sarcopenic dysphagia, including Shaker exercise, Mendelsohn maneuver, tongue-hold swallow exercise, jaw-opening exercise, swallow resistance exercise, lingual exercise, expiratory muscle strength training, neuromuscular electrical stimulation, and repetitive peripheral magnetic stimulation. We hope that some procedures mentioned in this article or new methods will be effective to treat sarcopenic dysphagia. PMID:35215427 | DOI:10.3390/nu14040778 View on the web Inoreader.

Long-term outcomes and cost-effectiveness of a magnet-based valve voice prosthesis for endoprosthesis leakage treatment

xlomafota13 shared this article with you from Inoreader Long-term outcomes and cost-effectiveness of a magnet-based valve voice prosthesis for endoprosthesis leakage treatment 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. 2022 Feb 26. doi: 10.1007/s00405-022-07313-x. Online ahead of print. ABSTRACT PURPOSE: Tracheoesophageal speech is considered the gold standard for rehabilitation following total laryngectomy. The main reason of voice prosthesis failure is the endoprosthesis leakage. Provox ActiValve® incorporates a magnet-based valve system to achieve active closure of the valve to treat these leakages, with the drawback of being significantly more expensive. The aim of the study was to compare the Provox Vega® and Provox ActiValve® duration and costs in patients with replacements increase due to endoprosthetic leakage. METHODS: Prospective case-crossover study in laryngectomized patients with Provox Vega® and endoprosthesis leakage to whom a Provox ActiValve® was placed. Survival and possible factors that affect voice prosthesis were studied using Kaplan-Meie r curves and Cox Proportional Hazards Regression. Cost-effectiveness analysis from the perspective of the Spanish Public National Health System with incremental cost-effectiveness calculation was performed. RESULTS: A total of 159 prostheses were evaluated. The most frequent reason for replacement was the endoprosthesis leakage (N = 129; 83.77%) in both models. The mean duration-time of Provox Vega® was 44.77 ± 2.82 days (CI 95%, 39.18-50.35; median 36 days), and 317.34 ± 116.8 days (CI 95% 86.66-548; median 286 days) for the Provox ActiValve® (p < 0.000). For every replacement not made thanks to the Provox ActiValve® there was saving of 133.97€ CONCLUSIONS: The Provox ActiValve® is a cost-effective solution in patients with increased prosthesis replacements due to endoprosthetic leakage, reducing the number of changes and cost compared to Provox Vega®.

Effects of Different Voice Rest on Vocal Function After Microlaryngeal Surgery: A Systematic Review and Meta‐Analysis

xlomafota13 shared this article with you from Inoreader Effects of Different Voice Rest on Vocal Function After Microlaryngeal Surgery: A Systematic Review and Meta‐Analysis Via The Laryngoscope Abstract Objectives To compare the results of a voice handicap index (VHI) scale and acoustic parameters in patients who underwent microlaryngeal surgery followed by either short-duration (voice rest for <7 days) or long-duration (≥7 days) voice rest. Study Design Systematic review and meta-analysis. Methods The PubMed, Embase, and Cochrane Library databases were systematically searched for articles published before March 1, 2021. Randomized controlled trials (RCTs) that measured the voice outcomes of patients after different durations and extents of postoperative voice restriction were included in the meta-analysis. Results Four RCTs comprising 112 patients were included in the quantitative meta-analysis. Compared with the long-duration voice rest group, the short-duration group exhibited comparable VHI scores (mean difference [MD], −7.01; 95% CI, −16.12 to 2.09; p = 0.13), maximum phonation time (MD, −2.58; 95% CI, −5.42 to 0.26; p = 0.07), and acoustic variables of jitter (MD, −1.25; 95% CI, −3.43 to 0.94; p = 0.26) and shimmer (MD, −0.79; 95% CI, −2.08 to 0.51; p = 0.24). Subgroup analysis for benign pathology and cold instruments studies demonstrated significantly better VHI scores (MD, −14.45; 95% CI, −26.19 to −2.72; p = 0.02 and MD, −15.98; 95% CI, −28.52 to −3.44; p = 0.01, respectively) in the short-duration group. Conclusions The limited evidence does not demonstrate benefit in voice outcomes from long-duration voice rest and suggests potential unfavorable effects on compliance and quality of life, providing a rationale for short-duration voice rest after microlaryngeal surgery. More studies are required to determine the optimal duration and extent of postoperative voice rest. Level of Evidence 1 Laryngoscope, 2022 View on the web Inoreader.

Performers' Perceptions of Vocal Function During Oral Steroid Treatment of Vocal Fold Edema

xlomafota13 shared this article with you from Inoreader Performers' Perceptions of Vocal Function During Oral Steroid Treatment of Vocal Fold Edema Via The Laryngoscope Objectives Acute vocal fold edema (VFE) is often a consequence of illness, allergy, or voice overuse, causing dysphonia. Although VFE typically resolves with voice rest and treatment of predisposing causes, oral glucocorticoids are often considered for performers with imminent performance demands. There are limited data about performers' perceptions of vocal change during treatment and how this relates to their ability to perform. This study aims to examine performers' self-perceptions of vocal function with steroid treatment. Methods Fifty-five performers (34 F; 21 M) diagnosed with VFE who chose treatment with a 6-day methylprednisolone taper were prospectively assessed. They completed the Evaluation of the Ability to Sing Easily (EASE) and reported on their voice use, regimen, performance obligations, and ability to perform. Findings were compared between Day 1 and Day 6 using paired t-tests and nonparametric Wilcoxon signed-rank tests. Results Nearly all subjects completed scheduled performances without interruption. Following treatment, all subscales of the EASE were decreased at Day 6 (Vocal Function 29.78–20.59; Pathologic Risk Indicator 26.60–17.33; Vocal Concerns 6.10–4.20). These differences were statistically significant (p < 0.0001) and greater in subjects with performances scheduled and subjects who consistently completed vocal warmups. These findings demonstrate significant improvement in several facets of performers' self-perception of function. Conclusion Subjects reported significant improvement in vocal function with oral steroid treatment and were able to meet performance obligations. It remains important that steroids are not prescribed without laryngeal examination. Examination should be repeated when dysphonia persists, recurs swiftly, or when patients seek repeated treatment, as there may be increased risk of adverse outcomes, and continued steroid use may mask underlying chronic pathology that is best treated by other means.

Risk factors for residual dizziness in patients with benign paroxysmal positional vertigo after successful repositioning: a systematic review and meta-analysis

xlomafota13 shared this article with you from Inoreader Risk factors for residual dizziness in patients with benign paroxysmal positional vertigo after successful repositioning: a systematic review and meta-analysis 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. 2022 Feb 26. doi: 10.1007/s00405-022-07288-9. Online ahead of print. ABSTRACT PURPOSE: To investigate the risk factors for residual dizziness (RD) in patients with benign paroxysmal positional vertigo (BPPV) after successful repositioning. METHODS: Searches were performed in PubMed, Embase, Cochrane library, Web of Science, Chinese National Knowledge Infrastructure, and Sino Med up to March 7, 2021 and references of relevant articles were screened. Data from eligible studies were meta-analyzed using Stata version 16.0 and Review Manager 5.4. RESULTS: In this systematic review and meta-analysis of 4487 patients from 31 studies, the prevalence of RD was 43.0% (95% CI 39.0-48.0%). Age (MD 4.17; 95% CI 2.13-6.21, P = 0.000), female gender (OR = 1.28, 95% CI 1.11-1.47, P = 0.001), secondary BPPV (OR 1.88; 95% CI 1.27-2.77, P = 0.001), a longer duration of BPPV before treatment (MD 3.45; 95% CI 1.87-5.0 2, P = 0.000), abnormal ocular vestibular evoked myogenic potential (OVEMP, OR 4.34; 95% CI 2.78-6.78, P = 0.000), abnormal cervical vestibular evoked myogenic potential (CVEMP, OR 2.48; 95% CI 1.54-3.99, P = 0.000), higher Dizziness Handicap Index (DHI) score before treatment (MD 10.88; 95% CI 5.96-15.80, P = 0.000), anxiety (OR 9.58; 95% CI 6.32-14.52, P = 0.000), osteopenia (OR = 4.40, 95% CI 2.17-8.96, P = 0.000), onset in winter (OR 7.27; 95% CI 2.38-22.24, P = 0.001) and with a history of BPPV (OR 1.79; 95% CI 1.06-3.04, P = 0.03) are the risk factors for RD in patients with BPPV after successful repositioning. The affected side, location or type of semicircular involvement, hyperlipidemia, diabetes, hypertension, heart disease, migraine, sleep disorders, canalolithiasis/cupulolithiasis, the number of times the canalith repositioning procedures (CRPs) were performed and number of vertigo attacks did not correlate with the occurrence of RD. CONCLUSIONS: Despite successful treatment, nearly half of the BPPV patients developed RD. RD seems to be a syndrome caused by multiple factors. The pathogenesis of most factors can be explained by psychological and/or physical disorders. Early recognition of these risk factors contributes to the prevention and treatment of RD.

Anatomical features of the iliocapsularis muscle: a dissection study

xlomafota13 shared this article with you from Inoreader Anatomical features of the iliocapsularis muscle: a dissection study Via radiol anat Surg Radiol Anat. 2022 Feb 26. doi: 10.1007/s00276-022-02905-y. Online ahead of print. ABSTRACT PURPOSE: Iliocapsularis (IC) overlies the anteromedial hip capsule and is an important landmark in anterior approaches to hip arthroplasty. Previously believed to be part of iliacus, few publications describe the prevalence, attachments, fibre direction, blood supply, innervation, and size of IC. This study was aimed to determine these anatomical features using embalmed bodies and whether they vary between sides, sex, and age. METHODS: Thirty-eight formalin-fixed adult bodies were dissected and the prevalence, presence of a connective tissue raphe, attachments, fibre direction, blood supply, and innervation, were documented. Length and width were measured, and significant differences were investigated with t tests. RESULTS: Iliocapsularis was present in all bodies examined, originating from the inferior border of the anterior inferior iliac spine, and inserting 20 mm distal to the lesser trochanter in 54 muscles (71%). Iliocapsularis was supplied by a thin branch from the femoral nerve and by branches of the lateral circumflex femoral and deep femoral arteries and veins. Muscle fibre direction was from superolateral to inferomedial. Mean length was 116.8 ± 11.2 mm and width was 12.8 ± 3.1 mm, with no significant differences between sides, sex, and age. CONCLUSION: This was the first study to document the venous drainage and compare the di mensions with sides, sex, and age, using adult bodies. However, the true function of IC is still unknown. Iliocapsularis is a constant muscle, distinct from iliacus, which is relevant to orthopaedic surgeons and physical rehabilitation specialists, particularly for postoperative patient care.

Prognostic significance of wait time for radical radiotherapy in locoregionally advanced nasopharyngeal carcinoma

xlomafota13 shared this article with you from Inoreader Prognostic significance of wait time for radical radiotherapy in locoregionally advanced nasopharyngeal carcinoma Via Head & Neck Abstract Background The prognostic significance of wait time between definite diagnosis and initial radical radiotherapy is not well established in patients with locoregionally advanced nasopharyngeal carcinoma (LA-NPC) receiving both induction chemotherapy (IC) and concurrent chemoradiotherapy (CCRT). Methods From 2010 to 2018, 648 patients with LA-NPC treated with IC followed by CCRT were included. Results A total of 172 pairs of patients with LA-NPC were selected by propensity score matching (PSM). Compared to patients with an acceptable wait time (≤75 days), patients with a prolonged wait time (>75 days) had a significant lower 5-year DMFS rate (86.6% vs. 74.1%, p = 0.006). Subgroup analyses indicated that the unfavorable effects of longer waiting times were mainly seen among stage IVa patients. Conclusions A prolonged wait time (>75 days) between definite diagnosis and initial radical radiotherapy has negative prognostic effects on patients with LA-NPC receiving IC plus CCRT, particularly those with IVa stage.
