Retrospective analysis of adjuvant therapy using dabrafenib plus trametinib in Japanese patients with advanced melanoma: analysis of 36 cases

xlomafota13 shared this article with you from Inoreader Retrospective analysis of adjuvant therapy using dabrafenib plus trametinib in Japanese patients with advanced melanoma: analysis of 36 cases Via Melanoma Research - Published Ahead-of-Print Patients with resected stage IIIB, IIIC and IIID melanomas have a high risk of recurrence. Therefore, an appropriate protocol for stage III melanoma is needed. Since adjuvant dabrafenib plus trametinib (D+T) combined therapy and anti-PD1 antibody (Ab) therapy reduce the risk of recurrence in patients with resected st age III BRAF-mutated melanoma, selecting the adjuvant therapy for BRAF-mutated melanoma is controversial. The efficacy and safety profiles of D+T combined therapy in the adjuvant setting were retrospectively analyzed in 36 Japanese. BRAF-mutated advanced melanoma patients. The relapse-free rate (RFR) at 12 months was 82.1% (95% confidential interval (CI), 63.9–92.6%). In the 21 patients who completed the protocol, the RFR at 12 months was 85.7% (95% CI, 64.5–95.9%). In the seven patients whose protocol was interrupted by adverse events, the RFR was 71.4% (95% CI, 35.2–92.4%). The incidence rate of any AEs for all patients was 69.7% (95% CI, 52.5–82.8%), including 13 cases of pyrexia, five cases of skin rash and four cases of liver dysfunction. The present study suggested that D+T therapy in the adjuvant setting is a useful and very tolerable protocol for BRAF-mutated melanoma in the Japanese population.

Lower melanoma pulmonary metastatic burden in obese mice: role of FGF-21

xlomafota13 shared this article with you from Inoreader Lower melanoma pulmonary metastatic burden in obese mice: role of FGF-21 Via Melanoma Research - Published Ahead-of-Print Obesity is a risk factor for malignant melanoma. The lungs are main target organs for metastization and their immune response is a key modulator of this mechanism. The concept that the metastatic potential of some types of cancer is reduced or inhibited by obesity, known as the obesity paradox, drives major concerns on the prognosis of metastasized patients. The aim of this study was to investigate how high-fat diet (HFD)-induced obesity affects melanoma metastization. C57Bl6/J mice were fed with HFD or standard diet for 180 days and inoculated intravenously with B16F10 melanoma cells. Upon 21 days of inoculation, lung tissue of overweight and lean mice was assessed for histology and immunohistochemistry assays. Adipokine antibody arrays were performed in mice serum. In vitro RAW 264.7 macrophage cultures were established and incubated with FGF-21 and/or lipopolysaccharide (LPS). Conditioned media was added to B16F10 cells for viability quantification. HFD-fed mice presented a reduced number of metastases with lower proliferative rates. The high content of inflammatory foci observed in noninoculated obese mice was significantly decreased upon B16F10 inoculation, concurrent with a slight fibrosis reduction. Plasma levels of fibroblast growth factor-21 (FGF-21), an endocrine regulator, were elevated in noninoculated HFD mice and the expression of FGF receptor 1 (FGFR-1) was significantly upregulated after inoculation. FGF-21 reduced melanoma viability in LPS-stimulated macrophages. Altogether, these findings suggest that higher amounts of FGF-21 are able to counterbalance the proinflammatory effects associated with obesity, protecting the lungs from melanoma metastization.

Effect of Glycerol Administration on ECochG and VEMP Findings in Individual with Meniere's Disease

xlomafota13 shared this article with you from Inoreader Effect of Glycerol Administration on ECochG and VEMP Findings in Individual with Meniere's Disease Via Otolaryngology Indian Abstract The present study aimed to find the effect of glycerol administration on Electrocochleography (ECochG), cervical and ocular Vestibular Evoked Myogenic Potential (c-VEMP, o-VEMP) findings in individual with Meniere's disease. Sixteen participants (32 ears) diagnosed with Meniere's disease underwent ECochG, c-VEMP and o-VEMP for both pre and 1 h post-glycerol administration. Paired t-test indicated that the SP/AP ratio of ECochG measures was significantly improved with post-glycerol administration. There was no significant difference in the mean amplitude of o-VEMP and c-VEMP between pre and post-glycerol administration. However, while individual differences were compared, 75% of the participants reported either improvement in c-VEMP amplitude or newly emerging c-VEMP& o-VEMP. Based on the recommendation by Adams et al. (Otolaryngol Clin North Am 43(5):995–1009, 2010), the improvement on these tests results with post glycerol administration were cons idered as a significant indicator for the presence of Meniere's disease.With post glycerol administration, the present study found that 84%of participants were found to have an improvement in the amplitude for ECochG measures. There was an improvement in the amplitude measures of o-VEMP and c-VEMP, which were observed in 75% and 68%of participants respectively with post-glycerol administration. Improvement in the amplitude of test measures with post-glycerol administration were observed to be more for cochlear potentials of ECochG followed by vestibular potentials of c-VEMP and o-VEMP. Thus, improvement of ECochG amplitude with post-glycerol administration might serve as an additional indicator for the presence of Meniere's disease. View on the web Inoreader.

The Efficacy of Septal Quilting Sutures Versus Nasal Packing in Septoplasty

xlomafota13 shared this article with you from Inoreader The Efficacy of Septal Quilting Sutures Versus Nasal Packing in Septoplasty Via Otolaryngology Indian Abstract Nasal packing is the classic method adopted by many otolaryngologists to stabilize the nasal septum and decrease the occurrence of postoperative bleeding and septal hematoma after septoplasty. However, because of its associated postoperative morbidity, many surgeons started to adopt alternative methods. This study aimed to assess the outcome and benefits of septal quilting sutures in comparison to nasal packing after septoplasty. A prospective non-randomized comparative interventional study was carried out at two teaching hospitals in Mosul city from January 2020 to January 2021. A total of 60 patients who were candidates for septoplasty, were included in the study. According to the surgeon's preference; 30 patients had placement of septal quilting sutures (group A), and in the other 30 patients nasal packing was performed (group B). Patients were assessed for postoperative morbidity and early outcome in the first 24 h, 1 week and 1 month postopera tively. In the first 24 h after septoplasty, patients in group B had significantly higher levels of nasal/facial pain, headache, sleep disturbance, breathing difficulties and swallowing difficulties compared to group A (p < 0.001). Over the follow up period of 1 month, no significant differences were recorded regarding postoperative bleeding, hematoma, infection, adhesions formation and septal perforation between the two groups (p > 0.05). Septal quilting sutures technique is more favorable in the early period in terms of patient discomfort after septoplasty, better nasal block and nasal/facial pain, the absence of misery on pack removal, with minimal bleeding after surgery.

Fully Automated Measurement of Cochlear Duct Length From Clinical Temporal Bone Computed Tomography

xlomafota13 shared this article with you from Inoreader Fully Automated Measurement of Cochlear Duct Length From Clinical Temporal Bone Computed Tomography Via The Laryngoscope Objectives/Hypothesis To present and validate a novel fully automated method to measure cochlear dimensions, including cochlear duct length (CDL). Study Design Cross-sectional study. Methods The computational method combined 1) a deep learning (DL) algorithm to segment the cochlea and otic capsule and 2) geometric analysis to measure anti-modiolar distances from the round window to the apex. The algorithm was trained using 165 manually segmented clinical computed tomography (CT). A Testing group of 159 CTs were then measured for cochlear diameter and width (A- and B-values) and CDL using the automated system and compared against manual measurements. The results were also compared with existing approaches and historical data. In addition, pre- and post-implantation scans from 27 cochlear implant recipients were studied to compare predicted versus actual array insertion depth. Results Measurements were successfully obtained in 98.1% of scans. The mean CDL to 900° was 35.52 mm (SD, 2.06; range, [30.91–40.50]), the mean A-value was 8.88 mm (0.47; [7.67–10.49]), and mean B-value was 6.38 mm (0.42; [5.16–7.38]). The R 2 fit of the automated to manual measurements was 0.87 for A-value, 0.70 for B-value, and 0.71 for CDL. For anti-modiolar arrays, the distance between the imaged and predicted array tip location was 0.57 mm (1.25; [0.13–5.28]). Conclusion Our method provides a fully automated means of cochlear analysis from clinical CTs. The distribution of CDL, dimensions, and cochlear quadrant lengths is similar to those from historical data. This approach requires no radiographic experience and is free from user-related variation.

Lesser Known Uses of γ‐Aminobutyric Acid Analogue Medications in Otolaryngology

xlomafota13 shared this article with you from Inoreader Lesser Known Uses of γ‐Aminobutyric Acid Analogue Medications in Otolaryngology Via The Laryngoscope Objectives/Hypothesis In otolaryngology, γ-aminobutyric acid (GABA) analogues have been previously analyzed for their roles in neuropathic pain, chronic cough, tinnitus, and perioperative analgesia. The primary aim of this study is to comprehensively summarize and synthesize the existing evidence for lesser known uses of gabapentin and pregabalin in otolaryngology. Study Design A scoping review conducted of the available English-language literature was performed by two authors through April 1, 2021. Methods The Preferred Reporting Items for Systematic Review and Meta-Analysis criteria were followed, and a quality assessment of included studies was performed using the Methodological Index for Non-Randomized Studies. Results Ten studies met inclusion criteria. Three studies found that gabapentin may reduce gastrostomy tube usage and improve swallowing function in head and neck cancer patients undergoing radiation therapy (RT). Three studies suggested that gabapentin may help reduce opiate use when used as a primary analgesic in patients with radiation-induced mucositis. One study demonstrated that pregabalin-reduced trismus severity in patients with radiotherapy-induced trismus. One study demonstrated gabapentin may be useful in patients with phonasthenia. Two studies demonstrated that GABA analogues may be a useful adjunct in patients with globus pharyngeus in the context of likely laryngeal sensory neuropathy. Conclusions The most promising potential uses for GABA analogues identified in this review are for improving swallowing, trismus, and narcotic overuse after RT. The benefit of GABA analogues for improving nonorganic voice disorders is also promising while the benefit for globus pharyngeus when possibly related to laryngeal sensory neuropathy is inconclusive.

Pilot study on the value of Raman spectroscopy in the entity assignment of salivary gland tumors

xlomafota13 shared this article with you from Inoreader Pilot study on the value of Raman spectroscopy in the entity assignment of salivary gland tumors Via Head and neck cancers by Till Jasper Meyer, Elena Gerhard-Hartmann, Nina Lodes, Agmal Scherzad, Rudolf Hagen, Maria Steinke, Stephan Hackenberg Background The entity assignment of salivary gland tumors (SGT) based on histomorphology can be challenging. Raman spectroscopy has been applied to analyze differences in the molecular composition of tissues. The aim of this study was to evaluate the suitability of RS for entity assignment in SGT. Methods Raman data were collected in deparaffinized sections of pleomorphic adenomas (PA) and adenoid cystic carcinomas (ACC). Multivariate data and chemometric analysis were completed using the Unscrambler software. Results The Raman spectra detected in ACC samples were mostly assigned to nucleic acids, lipids, and amides. In a principal component-based linear discriminant analysis (LDA) 18 of 20 tumor samples were classified correctly. Conclusion In this proof of concept study, we show that a reliable SGT diagnosis based on LDA algorithm appears possible, despite variations in the entity-specific mean spectra. However, a standardized workflow for tissue sample prep aration, measurement setup, and chemometric algorithms is essential to get reliable results. View on the web Inoreader.
