Voice Symptoms and Wellbeing in School Teachers in England

xlomafota13 shared this article with you from Inoreader
Negative psychological factors such as depression and other common mental disorders have been found to be associated with voice problems in teachers. However, there is little research with teachers that investigates the relationship between positive psychological factors such as wellbeing and voice problems. Although negative and positive mental states are on a continuum of psychological health, research suggests negative and positive effects are not necessarily inversely correlated and therefore need to be investigated separately.

J Am Coll Surg. 2022 Apr 1;234(4):691-700. doi: 10.1097/XCS.0000000000000107.

ABSTRACT

BACKGROUND: Early-stage thyroid cancers have excellent survival. However, lymph node metastases (LNM) confer a worse prognosis and are not always known preoperatively. Therefore, investigation on the clinical and histological factors predictive of LNM in thyroid cancers was conducted to tailor the extent of surgery and radioactive iodine therapy.

STUDY DESIGN: Multivariate logistic regressi ons were performed based on retrospective data from thyroid cancer patients seen between 2013 and 2020 at a single institution.

RESULTS: Among 913 patients, mean age was 49.4 years, 76.5% were female, 58.3% were White, 21.2% were Black, and 27.9% had LNM. In the multivariate analyses in which the outcome was LNM, White (odds ratio [OR] 1.74, 95% CI 0.98 to 3.15, p = 0.064) and Hispanic patients (OR 2.36, 95% CI 0.97 to 5.77, p = 0.059) trended toward higher risk of LNM compared to Black patients, whereas age (OR 0.98, 95% CI 0.97 to 1.00, p = 0.008) showed protective effect. Tumor size (OR 1.04, 95% CI 1.01 to 1.07, p = 0.007), extrathyroidal extension (OR 2.46, 95% CI 1.53 to 3.97, p < 0.001), lymphovascular invasion (OR 6.30, 95% CI 3.68 to 11.14, p < 0.001), and multifocality (OR 1.47, 95% CI 1.01 to 2.12, p = 0.042) were associated with higher risk of LNM. In another model with outcome as >5 LNM, tumor size (OR 1.07, 95% CI 1.03 to 1.11, p = 0.001), age (OR 0.95, 95% CI 0.93 to 0.97, p < 0.001), extrathyroidal extension (OR 3.20, 95% CI 1.83 to 5.61, p < 0.001), and lymphovascular invasion (OR 6.82, 95% CI 3.87 to 12.17, p < 0.001) remained significant predictors.

CONCLUSION: Our analyses demonstrated and confirmed that age, tumor size, extrathyroidal extension, and lymphovascular invasion are independent predictors of significant LNM, thereby conferring higher risk of recurrence. Risk of LNM based on these patient characteristics should be considered when planning an operative approach.

Rev Esp Med Nucl Imagen Mol (Engl Ed). 2022 Mar-Apr;41(2):71-77. doi: 10.1016/j.remnie.2021.04.017. Epub 2021 May 25.

ABSTRACT

OBJECTIVE: To evaluate the use of radioactive iodine-125 seed (RIS) in breast and/or axillary surgery, in patients with breast cancer treated with neoadjuvant chemotherapy (NAC).

MATERIAL AND METHODS: Prospective study between January 2016 and June 2020. 80 women T1-3,N0-2,M0: 30 RIS marking the breast tumor, 36 both the tumor and the biopsied positiv e axillary node, and 14 only the axilla. Age: 54.7 ± 11.4 years. Tumor size: 34.1 ± 14.6 mm. Histological type: invasive ductal carcinoma 90.0%. Molecular subtypes: luminal-A 23.8%, luminal-B/HER2- 33.7%, luminal-B/HER2+ 18.8%, HER2+ 7.5%, basal-like 16,2%.

RESULTS: Of the 66 patients with RIS marking of the tumor (51 pre-NAC, 15 post-NAC), 92.1% had tumor-free surgical margins, with a specimen volume of 126.7 ± 111.2 cm3. Of the 5 s local excisions, in 3 the resection margin was involved (1 mastectomy). Of the 50 patients N1 with RIS marking (MLN), 44 pre-NAC and 6 post-NAC, MLN was identified in 97.2%: negative 23, positive 26. In 45/50 patients, sentinel node biopsy (SNB) was performed and it was identified in 93.3%: negative 26, positive 16. In 1 case RIS was not placed correctly and SNB was not identified due to non-migration. In 61.9% of the patients, MLN was among the SNB identified in the surgery. In 5 patients with mismatched SNB and MLN, the pathologica l result of the SNB was negative and the MLN was positive. Axillary lymph node dissection was performed in 53.8% of the patients.

CONCLUSION: RIS allow to perform breast-conserving surgery and improve detection of residual axillary disease in patients treated with NAC.

Deep brain stimulation of subthalamic nucleus modulates cortical auditory processing in advanced Parkinson's Disease

xlomafota13 shared this article with you from Inoreader

PLoS One. 2022 Feb 24;17(2):e0264333. doi: 10.1371/journal.pone.0264333. eCollection 2022.

ABSTRACT

Deep brain stimulation (DBS) has proven its clinical efficacy in Parkinson's disease (PD), but its exact mechanisms and cortical effects continue to be unclear. Subthalamic (STN) DBS acutely modifies auditory evoked responses, but its long-term effect on auditory cortical processing remains ambiguous. We studied with magnetoencephalography the effect of long-term STN DBS on auditory processing in patients with advanced PD. DBS resulted in significantly increased contra-ipsilateral auditory response latency difference at ~100 ms after stimulus onset compared with preoperative state. The effect is likely due to normalization of neuronal asynchrony in the auditory pathways. The present results indicate that STN DBS in advanced PD patients has long-lasting effects on cortical areas outside those confined to motor processing. Whole-head magnetoencep halography provides a feasible tool to study motor and non-motor neural networks in PD, and to track possible changes related to cortical reorganization or plasticity induced by DBS.

Pediatric morphometric study to guide the optimized implantation of the Osia® 2 implant system

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2022 Mar 16. doi: 10.1007/s00405-022-07338-2. Online ahead of print.

ABSTRACT

PURPOSE: Continuous technological advances result in the availability of new bone conduction hearing implants, of which their suitability for pediatric patients is of major concern. The CochlearTMOsia® 2 is a new active osseointegrated steady-state implant system that uses digital piezoelectric stimulation to treat hearing loss. The implant in the United States was approved for patients aged 12 years and above, whereas the CE mark is independent of age, the only requirement is body weight of at least 7 kg. Therefore, further clinical studies are required to assess device characteristics in younger patients. The aim of our study was to perform a morphometric study among 5-12-year-old children, and to develop a surgical protocol for Osia 2 system implantation based on these findings.

METHODS: We examined r etrospectively cranial CT scans of 5-12-year-old patients from our clinical database. We measured the bone and soft-tissue thickness in the region of interest, and the position of the sigmoid sinus. 3D printed temporal bones were also used for planning.

RESULTS: Soft-tissue thickness varied between 3.2 ± 0.5 mm and 3.6 ± 0.6 mm and bone thickness varied between 3.5 ± 1.1 mm and 4.7 ± 0.3 mm. The sigmoid sinus was located 1.3 ± 0.2 cm posterior to the ear canal, and the anterior distance was 4.8 ± 0.9 to 7.1 ± 1.1 mm.

CONCLUSIONS: Our morphometric studies showed that patients aged 5-12 have different anatomical dimensions compared to adults, but that implantation of the Osia 2 system is feasible in these patients using an altered implant positioning recommended by our data. The Cochlear™ Osia® 2 is, therefore, an option for hearing rehabilitation in younger pediatrics.

The feasibility of SHIMP for judging subjective vertigo and recovery in patients with vestibular neuritis

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2022 Mar 16. doi: 10.1007/s00405-022-07299-6. Online ahead of print.

ABSTRACT

PURPOSE: We aimed to study the results of the head impulse paradigm (HIMP) and the suppression head impulse paradigm (SHIMP) in patients with acute vestibular neuritis (AVN) to compare dizziness handicap inventory (DHI) scores before and after treatment. We also wanted to investigate the correlation between the HIMP, SHIMP and DHI score and to analyze the factors that affect the recovery with AVN in the short term.

METHODS: The HIMP, SHIMP, and DHI score were assessed in 20 patients with AVN before (T0) and after treatment (T1). We collected the following indicators: T0, T1-HIMP VOR gain; T0, T1-SHIMP VOR gain; the percentage of the anti-compensatory saccades of T0-SHIMP and T1-SHIMP on the affected side; T0-DHI score, T1-DHI score; and efficacy index (EI). The correlation between HIMP and SHIMP parameters with the DHI score and EI was analyzed, and the factors that affect the recovery of patients with AVN were assessed.

RESULTS: T0-SHIMP anti-compensatory saccades (%),T1-SHIMP VOR gain, and T1-SHIMP anti-compensatory saccades (%) were significantly correlated with the corresponding DHI score and EI (P < 0.05). T0, T1-HIMP VOR gain and T0-SHIMP VOR gain had no correlation with the corresponding DHI score and EI (P > 0.05). T0-SHIMP anti-compensatory saccades (%) significantly affect EI (P < 0.05).

CONCLUSION: Both HIMP and SHIMP can assess the current vestibular function and recovery of AVN patients, but SHIMP can more accurately reflect the degree of subjective vertigo. At the same time, T0-SHIMP anti-compensatory saccades (%) can be used as a good index to evaluate the short-term recover y of AVN patients.

Via Polyps

Am J Speech Lang Pathol. 2022 Mar 10;31(2):912-922. doi: 10.1044/2021_AJSLP-21-00115. Epub 2022 Feb 18.

ABSTRACT

PURPOSE: Voice rest is frequently prescribed after phonosurgery, but optimal type and duration for voice outcomes have not been demonstrated. Studies to date have been characterized by heterogeneity in surgical procedures and laryngeal diagnoses. We sought to analyze the effect of recommended absolute voice rest duration on outcomes of microflap surgery for benign vocal fold lesions. A secondary purpose was to identify patient factors associated with postoperative voice outcomes.

METHOD: Forty-three patients were included in this retrospective review of patients aged 18 years and above who underwent direct microlaryngoscopy with microflap for vocal fold polyp or cyst over a 5-year period at a multidisciplinary voice center. Duration of recommended postoperative absolute voice rest was classified as less than 7 days, 7 days, a nd more than 7 days. Demographic and vocal hygiene data and voice treatment history were collected. Outcome measures consisted of one pre- and two postoperative Voice Handicap Index (VHI) scores. Effects of recommended voice rest on outcomes were analyzed using mixed models for repeated measures. Effects of patient factors on outcomes were analyzed as exploratory measures. Stroboscopy ratings were analyzed descriptively.

RESULTS: Thirteen patients were recommended 7 days of absolute voice rest, 15 were recommended less than 7 days, and 15 were recommended more than 7 days. Postoperatively, VHI scores significantly improved for all patients. Voice rest as a continuous variable was associated with the Functional subscale score in the short term, but there was no effect on VHI total score and no longer term effect of voice rest on any outcome. Age, sex, and preoperative voice therapy were associated with at least one VHI subscale score on at least one time point.

CONCLUSION : VHI outcomes of microflap surgery for polyps and cysts do not differ by duration of recommended absolute postoperative voice rest.
