A Prospective, Randomized, Controlled Trial of Methylene Blue Injection for Costal Cartilage Harvest Postoperative Analgesia.

Background: In plastic surgery, costal cartilage is an excellent support material. However, postoperative pain from costal cartilage harvesting can impact patient recovery and satisfaction with the surgery. Recent reports have shown that methylene blue (MB) is an effective local analgesic in postoperative management.

Feasibility of Intensive Voice Therapy for Pediatric Vocal Fold Nodules Delivered via Telepractice: Pilot Study.

Purpose: The aim of this study is to assess the feasibility of an intensive voice therapy delivered via telepractice for pediatric vocal fold nodules (VFNs).

Method: Ten children with VFNs (mean age = 6 years, range = 5-8 years) were recruited in this study. Assessments including stroboscopic ratings, acoustic parameters, aerodynamic and auditory perceptual measures, and parent-reported Pediatric Voice Handicap Index were administered pretreatment and within 1 week post treatment.

The Study of Speech Acoustic Characteristics of Elderly Individuals with Presbyphagia in Ningbo, China.

The feasibility of using acoustic parameters to predict presbyphagia has been preliminarily confirmed. Considering that age and gender can influence the results of acoustic parameters, this study aimed to further explore the specific effects of age and gender on acoustic parameter analysis of the elderly population over 60 years old with presbyphagia. A total of 45 participants were enrolled and divided into three groups (60-69 years old, 70-79 years old, and 80-89 years old).

Septal Extension Spreader Graft Combined With Warped Alar Batten Graft for Improvement of Nasal Tip and Alar Asymmetry in Adult Cleft Lip Nasal Deformity.

This paper presents the findings of an observational study involving 38 patients to evaluate the application of a surgical technique utilizing an autologous costal cartilage scaffold for correcting nasal tip and alar asymmetry in unilateral cleft lip-nasal deformity. Nasal septum extension spreader grafts (SEG) and warped alar batten grafts, both made from autologous costal cartilage, were utilized in open rhinoplasty procedures. The warped alar batten graft was fixed to the caudal end of the SEG, with the lower lateral cartilage on the cleft side suspended to the free part of the newly created warped alar batten graft to lift the collapsed nasal alar further.

DAFT-Net: Dual Attention and Fast Tongue Contour Extraction Using Enhanced U-Net Architecture.

In most silent speech research, continuously observing tongue movements is crucial, thus requiring the use of ultrasound to extract tongue contours. Precisely and in real-time extracting ultrasonic tongue contours presents a major challenge. To tackle this challenge, the novel end-to-end lightweight network DAFT-Net is introduced for ultrasonic tongue contour extraction.

TM-Score predicts immunotherapy efficacy and improves the performance of the machine learning prognostic model in gastric cancer.

Immunotherapy is becoming increasingly important, but the overall response rate is relatively low in the treatment of gastric cancer (GC). The application of tumor mutational burden (TMB) in predicting immunotherapy efficacy in GC patients is limited and controversial, emphasizing the importance of optimizing TMB-based patient selection. By combining TMB and major histocompatibility complex (MHC) related hub genes, we established a novel TM-Score.

Case report: A case of rare metastasis of gastric cancer to the axillary lymph node metastasis treated with combination immunotherapy.

Lymph node (LN) metastasis is a common mode of metastasis in advanced gastric cancer (GC), while axillary LN metastasis infrequently occurs in GC. There are few reports on this rare type of metastasis - especially its clinicopathological features - and systemic treatment are unclear. We describe a case of GC with extensive metastasis, including the rare axillary LN metastasis.

Lollipop-Like Costal Cartilage Graft with a Peach-Shaped Head for East Asian Rhinoplasty.

Background: Nasal tip refinement is a challenging step of East Asian rhinoplasty due to complex anatomical defects. Autologous costal cartilage grafts are commonly used to provide nasal tip support. This study aims to evaluate the efficacy and safety of a modified technique using a lollipop-like cartilage graft with a peach-shaped head.

Gender Attributions by Cisgender and Gender Diverse Listeners Rating Vowels, Reading, and Monologues.

Objectives: To determine if listeners' attributions of speakers' gender vary by linguistic context and/or the listeners' gender identity.

Methods: Seventeen self-identified transgender adults assigned male at birth were audio-recorded prolonging /a/, reading sentences, and saying spontaneous monologues. Eighteen adults (10 cisgender and 8 gender-diverse individuals) listened and used a 1-5 scale (1: very masculine, 2: somewhat masculine, 3: androgynous, 4: somewhat feminine, and 5: very feminine) to rate the gender attribution of each speech sample.

Comprehensive spatiotemporal mapping of single-cell lineages in developing mouse brain by CRISPR-based barcoding.

A fundamental interest in developmental neuroscience lies in the ability to map the complete single-cell lineages within the brain. To this end, we developed a CRISPR editing-based lineage-specific tracing (CREST) method for clonal tracing in Cre mice. We then used two complementary strategies based on CREST to map single-cell lineages in developing mouse ventral midbrain (vMB).

Chaos Behavior Analysis of Alaryngeal Voices Including Esophageal and Tracheoesophageal Voices.

Hypothesis/objectives: This study's objective was to develop a method to evaluate the chaotic characteristic of alaryngeal speech. The proposed method will be capable of distinguishing between normal and alaryngeal voices, including esophageal (SE) and tracheoesophageal (TE) voices. It has been previously shown that alaryngeal voices exhibit chaotic characteristics due to the aperiodicity of their signals.

Effects of Botulinum Toxin A on the Blood Flow in Expanded Rat Skin.

Poor blood supply can easily lead to expander extrusion and necrosis at the distal expanded flap. Botulinum toxin A (BTX-A) has been previously found to improve pedicled flap blood flow perfusion, but its effects on the blood supply of expanded skin remain unclear. Therefore, this study aimed to evaluate the effects of BTX-A on blood flow perfusion during and after expansion.

Conversion of plastic waste into fuels: A critical review.

Plastic wastes have posed serious threats to the environment, including decrease of soil nutrient effectiveness and agricultural production as well as emerge of ecological instability. Fuel conversion from plastic waste is regarded as a promising strategy for its disposal and energy utilization. Plastic wastes can be converted into target fuels by adjusting cracking of chemical bonds.

Effectiveness and Feasibility of Telepractice on Voice Therapy for Female Teachers in Elementary Schools with Self-Reported Voice Disorders.

Purpose: The purpose of this study is to explore the effectiveness of telepractice in voice intervention for female teachers in elementary schools with self-reported voice disorders.

Methods: Thirty-five female elementary school teachers with self-reported voice disorders volunteered to participate in the study. They were divided into a telepractice voice intervention group (experimental group N=18) and a face-to-face voice intervention group (control group N=17) based on their employment setting.

Stack-Up Technique to Create a Three-Dimensional Costal Cartilage Framework in Ear Reconstruction.

Ear reconstruction is one of the most challenging procedures for plastic surgeons. The costal cartilage is the most accepted material, and the framework fabrication methods also vary with the different ear reconstruction methods. This study aimed to present our clinical experience using a novel method for costal cartilage framework fabrication with the "fully expansion technique" ear reconstruction without a skin graft.
