ABSTRACT

OBJECTIVE: We aimed to evaluate the functional recovery of stroke patients with orophyaryngeal dysphagia after treatment with traditional swallowing therapy (TST), neuromuscular electrical stimulation (NMES), and kinesiology taping (KT), by using clinical swallowing assessments and objective fiberoptic endoscopic evaluation of swallowing (FEES).

METHODS: A total of 37 patients were randomized in three groups: those who received TST and NMES as Group 1 (n:12), those who received both TST and KT as Group 2 (n:13), and those who received TST, NMES, and KT together as Group 3 (n:12). Patients were evaluated before treatment, after treatment, and three months after treatment onset with bedside water-swallow test, Eating Assessment Tool (EAT-10), Functional Oral Intake Scale (FOIS), penetration-aspiration scale (PAS), and Nationa l Institute of Health-Swallow Safety Scale (NIH-SSS). FOIS, PAS, and NIS-SSS were completed according to results of fiberoptic endoscopic evaluation of swallowing (FEES).

RESULTS: A statistically significant decrease was observed in bedside water-swallow test, EAT-10, PAS, and NIH-SSS scores in all treatment groups 5 weeks and 3 months after treatment onset compared to pre-treatment scores (p < 0.05). There was a statistically significant increase in FOIS scores 5 weeks and 3 months after treatment compared to pretreatment scores in all treatment groups (p < 0.05). When the pre-treatment, 3-week, and 5-month swallow scale scores of all groups were compared, there was no significant different difference in terms of bedside water-swallow test, EAT-10, FOIS, PAS, or NIH-SSS scores (p > 0.05).

CONCLUSION: According to the results of our study, KT is a new option in the treatment of stroke-related dysphagia, is an effective treatment approach and its efficacy is main tained throughout long-term follow-up.

Comparison of the value of ultrasound and enhanced magnetic resonance imaging in judging cervical lymph node metastasis in patients with oral cancer

xlomafota13 shared this article with you from Inoreader

Bull Cancer. 2021 Nov 12:S0007-4551(21)00423-9. doi: 10.1016/j.bulcan.2021.09.010. Online ahead of print.

ABSTRACT

BACKGROUND: Oral cancer is the twelfth largest malignant tumor in the world. Oral cancer is prone to lymph node metastasis in the early stages of the disease, and lymph node metastasis will directly affect the treatment and survival rate. Therefore, whether the lymph node metastasis can be accurately evaluated is of great significance to the treatment and prognosis of patients.

OBJECTIVE: The diagnostic efficacy of three methods of preoperative ultrasound, enhanced magnetic resonance (enhanced MR), and ultrasound combined with enhanced MR on cervical lymph node metastasis of oral cancer were compared.

MATERIALS AND METHODS: A retrospective analysis of 399 cases of oral cancer completed by head and neck surgery at Cancer Center of Sun Yat-sen University, China. In all cases, the maxillofacial and neck enhanced M R and cervical lymph node ultrasound examinations were performed before surgery, and imaging diagnosis was made for cervical lymph node metastasis and compared with pathology. All judgment results were statistically processed using the chi-square test.

RESULTS: Compared with the above three methods, the diagnostic efficiency of ultrasound alone is better, and the diagnostic efficiency of enhanced MR combined ultrasound is not significantly better than that of ultrasound alone. There are differences in the diagnostic efficacy of the three inspection methods in different clinical sub-periods, all of which are better for the diagnosis of stage I. For patients with stage I, II, and III, there were no differences between the three examination methods. However, for stage IV patients,the diagnostic efficiency of ultrasound alone is better. For patients with stage N0, there was no difference in diagnostic efficacy between the three methods. For the assessment of lymph nodes in the I-I II region, there are differences between the three methods of examination: the diagnostic efficiency of ultrasound alone is better, and enhanced MR combined ultrasound is not significantly better than ultrasound alone. For the evaluation of lymph nodes in the IV-VII region, there was no difference in diagnostic efficacy between the three methods.

CONCLUSION: According to the clinical characteristics and prognosis of patients with oral cancer, although enhanced MR can better evaluate the tumor, ultrasound may be considered as the preferred imaging method for cervical lymph node metastasis.

SIGNIFICANCE: Accurate assessment and proper and timely treatment of lymph node metastasis can help improve the survival rate of patients.

Bull Cancer. 2021 Nov 12:S0007-4551(21)00440-9. doi: 10.1016/j.bulcan.2021.09.016. Online ahead of print.

ABSTRACT

INTRODUCTION: Over the last 40years, the French health system has opened up to patient engagement. Society has recognised the legitimacy of the patient as a decision-maker in his or her own health and as an expert in his or her illness. This is true at the individual level in the context of doctor-patient relationship, and at the organisational level within institutions, in decision-making or academic groups. The aim of this study is to present the concepts of patient-partnership, patient education and to illustrate the different functions that patient-partners can take within the organisation of patient education programmes, and in the field of oncology.

METHOD: A narrative review of the literature was carried out to extract relevant and recent seminal articles to address these points.

RESULTS: The Montreal mo del establishes the patient partner as a full care actor. He can thus contribute his expertise in many fields of application: care, research or teaching. The aim of patient education is to empower the patient in the management of his or her disease, treatment and the consequences of these on daily life. The patient partner has a full place in this system where he can accompany his peers, but also collaborate with the educational team to develop new programmes, evaluate them and even conduct research. The implementation of these systems consists of getting individuals with different cultures and operating methods to work together. It is a process that requires time, effort and attention to each other.

Epigenetic therapy to enhance therapeutic effects of PD-1 inhibition in therapy-resistant melanoma

xlomafota13 shared this article with you from Inoreader

SocialThumb.00008390.DC.jpeg

Targeted therapy and immunotherapy have revolutionized the treatment of metastatic skin melanoma but around half of all patients develop resistance early or late during treatment. The situation is even worse for patients with metastatic uveal melanoma (UM). Here we hypothesized that the immunotherapy of therapy-resi stant skin melanoma or UM can be enhanced by epigenetic inhibitors. Cultured B16F10 cells and human UM cells were treated with the histone deacetylase inhibitor (HDACi) entinostat or BETi JQ1. Entinostat-induced HLA expression and PD-L1, but JQ1 did not. A syngeneic mouse model carrying B16-F10 melanoma cells was treated with PD-1 and CTLA4 inhibitors, which was curative. Co-treatment with the bioavailable BETi iBET726 impaired the immunotherapy effect. Monotherapy of a B16-F10 mouse model with anti-PD-1 resulted in a moderate therapeutic effect that could be enhanced by entinostat. Mice carrying PD-L1 knockout B16-F10 cells were also sensitive to entinostat. This suggests HDAC inhibition and immunotherapy could work in concert. Indeed, co-cultures of UM with HLA-matched melanoma-specific tumor-infiltrating lymphocytes (TILs) resulted in higher TIL-mediated melanoma killing when entinostat was added. Further exploration of combined immunotherapy and epigenetic therapy in metastatic melanoma resistant to PD-1 inhibition is warranted. * Present address: Harry Perkins Institute of Medical Research, 6 Verdun St, WA 6009, Nedlands, Perth, Australia.

The potential effects of obesity on predicting outcomes of velopharyngeal surgery for obstructive sleep apnea

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2021 Nov 16. doi: 10.1007/s00405-021-07175-9. Online ahead of print.

ABSTRACT

PURPOSE: To explore the outcome associated factors of velopharyngeal surgery for treating obstructive sleep apnea (OSA) and the effects of obesity.

METHODS: A total of 175 adult OSA patients who underwent velopharyngeal surgery, including the revised uvulopalatopharyngoplasty with uvula preservation (H-UPPP) alone or the combination of H-UPPP and transpalatal advancement pharyngoplasty, were retrospectively studied. The pre-operative information of these patients, including physical examination, polysomnography (PSG), and upper airway CT, were collected for analysis. Post-operative PSG used for evaluation of surgical outcomes were all done 3-6 months after surgery.

RESULTS: The overall AHI decreased significantly from 59.7 ± 18.8 events/h to 22.1 ± 18.8 events/h after surgery (P < 0.001), and there were 104 responde rs (59.4%). Tonsil size, the percentage of time with oxygen saturation below 90% (CT90), the vertical distance between the lower margin of the mandible and the lower margin of the hyoid (MH), and surgical methods were independently associated with treatment outcomes. The independent associated factors for surgical success were large tonsil size and combined surgical methods in non-obese patients (BMI < 27.5 kg/m2) and were large tonsil size, short MH, and low CT90 in obese patients (BMI ≥ 27.5 kg/m2), respectively.

CONCLUSIONS: Although BMI is not directly associated with surgical outcomes of velopharyngeal procedures, the outcomes associated factors in obese and non-obese OSA patients were not entirely the same. Obesity should be taken into accounts in pre-operative patient selection of such surgery.

Surg Radiol Anat. 2021 Nov 16. doi: 10.1007/s00276-021-02856-w. Online ahead of print.

ABSTRACT

PURPOSE: To describe a previously unreported anatomical variant of the hepatic arterial supply: a conjoined right hepatic artery, formed by branches of the common hepatic artery and gastroduodenal artery.

METHOD: A 54-year-old female with oligometastatic colorectal cancer with metastases to the liver presented for planning stage arteriography in preparation for Y90 radioembo lization.

RESULTS: Arteriography of the common hepatic artery demonstrated bifurcation into a right hepatic artery and gastroduodenal artery. The gastroduodenal artery gave rise to a proximal branch, from which the left hepatic artery originated and then continued to anastomose in the hilum of the liver to the right hepatic artery originating from the common hepatic artery. It was initially identified on visceral artery arteriography and then retrospectively recognized on pre-procedural CT scan.

CONCLUSION: Anatomical variants of the hepatic arterial supply are important to recognize during planning stage arteriography in preparation for Y90 radioembolization. Knowledge of these variants is also important for pre-operative planning.

Evaluating Strength of Evidence of Pediatric Otolaryngology Research Literature: A 20‐Year Review

xlomafota13 shared this article with you from Inoreader

Objectives/Hypothesis

Quantity and quality of Otolaryngology-Head and Neck Surgery (OTL-HNS) research are increasing, yet patterns within Pediatric OTL-HNS publications are unknown. This study examines trends in the level of evidence of pediatric OTL-HNS articles over a 20-year period to quantify the growth and characterize contributing factors.

Study Design

Review article.

Methods

A retrospective review was conducted on 12 peer-reviewed OTL-HNS journals at three time-points: 1996, 2006, and 2016. Pediatric-specific OTL-HNS journals were selected; all were among the top 10 highest impact factor journals, with one pediatric-specific and one Canadian journal. Publication details, author characteristics, and study focus were collected. Papers were classified based on the Oxford Centre for Evidence-Based Medicine Levels of Evidence by two independent reviewers.

Results

Of the 1,733 articles reviewed, 727 met inclusion criteria. A greater absolute number of pediatric OTL-HNS articles were published over the years studied: from 95 in 1996 to 359 in 2016 (P < .001). As well, the absolute number of high-quality studies has increased over the study period, from 28 articles in 1996 to 100 articles in 2016. However, the relative percentage of high-quality papers remained stable between 27.9% and 32.2% with an average of 29.7% (P = .89). Higher impact factor journals did not tend to publish higher-quality pediatric OTL-HNS articles (P = .48).

Conclusions

Over the past 20 years, there is no appreciable improvement in the proportion of high-quality publications in pediatric OTL-HNS; however, there is an overall greater number of high-quality papers within OTL-HNS literature. These findings likely relate to challenges of research within pediatric surgical specialties.

Phonation Threshold Pressure Revisited: Effects of Intrinsic Laryngeal Muscle Activation

xlomafota13 shared this article with you from Inoreader

Objectives/Hypothesis

Phonation threshold pressure (P th) is the minimum subglottic pressure required to reach phonation onset and is considered a marker for vocal efficiency and health. We investigated the effects of intrinsic laryngeal muscle (ILM) activation on P th.

Study Design

In vivo animal study.

Methods

In an in vivo canine phonation model, laryngeal adductor muscles were activated together by stimulation of the recurrent laryngeal nerves (RLNs) and individually via stimulation of respective terminal nerve branches. Cricothyroid (CT) muscles were activated via stimulation of the superior laryngeal nerves. ILMs were activated in a graded manner at various combinations as transglottal airflow was gradually increased. Aerodynamic and glottal posture parameters were measured at phonation onset.

Results

Graded RLN stimulation decreased glottal distance and increased P th. Thyroarytenoid (TA) muscle activation alone increased P th. Lateral cricoarytenoid (LCA) muscle activation alone had minimal effects. However, graded TA activation as a function of LCA activation level revealed a synergistic relationship between the two muscles in increasing P th. Effects of CT activation were dependent on adductor stimulation level: CT activation increased P th at low RLN stimulation levels and decreased P th at high RLN levels.

Conclusions

The effects of ILM activation on P th were consistent with their expected effects on vocal fold stiffness and tension. TA was the primary adductor controlling P th. While LCA alone had minimal effects on P th, it enhanced the role of TA in controlling P th. TA and CT have antagonistic roles in controlling P th. These relationships should be considered in clinical efforts to improve ease of phonation and vocal efficiency.
