OBJECTIVE
To systematically review vagus nerve stimulation (VNS) studies to present data on the safety and efficacy on motor recovery following stroke, traumatic brain injury (TBI), and spinal cord injury (SCI).
METHODS
Data sources: PubMed, EMBASE, SCOPUS, and Cochrane.
STUDY SELECTION
Clinical trials of VNS in animal models and humans with TBI and SCI were included to evaluate the effects of pairing VNS with rehabilitation therapy on motor recovery.
DATA EXTRACTION
Two reviewers independently assessed articles according to the evaluation criteria and extracted relevant data electronically.
DATA SYNTHESIS
Twenty-nine studies were included; 11 were animal models of stroke, TBI, and SCI, and eight involved humans with stroke. While there was heterogeneity in methods of delivering VNS with respect to rehabilitation therapy in animal studies and human non-invasive studies, a similar methodology was used in all human-invasive VNS studies. In animal studies, pairing VNS with rehabilitation therapy consistently improved motor outcomes compared to controls. Except for one study, all human invasive and non-invasive studies with controls demonstrated a trend toward improvement in motor outcomes compared to sham controls post-intervention. However, compared to non-invasive, invasive VNS, studies reported severe adverse events such as vocal cord palsy, dysphagia, surgical site infection, and hoarseness of voice, which were found to be related to surgery.
CONCLUSION
Our review suggests that VNS (non-invasive or invasive) paired with rehabilitation can improve motor outcomes after stroke in humans. Hence, VNS human studies are needed in these populations (referring to SCI and TBI?) or just SCI. There are risks related to device implantation to deliver invasive VNS compared to non-invasive VNS. Future human comparison studies are required to study and quantify the efficacy vs. risks of paired VNS delivered via different methods with rehabilitation, which would allow patients to make an informed decision.

Endocrine May 2024To evaluate the safety and efficacy of radiofrequency ablation (RFA) in treating locoregional recurrent thyroid cancer (LRTC) after a 2-year follow-up time.
PURPOSE
To evaluate the safety and efficacy of radiofrequency ablation (RFA) in treating locoregional recurrent thyroid cancer (LRTC) after a 2-year follow-up time.
METHODS
PubMed, Embase and Cochrane Library were searched from inception until 20 September 2022 to find studies reporting the safety and efficacy of RFA in LRTC patients after a 2-year follow-up. Two radiologists performed the data extraction and methodological quality assessment according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
RESULTS
We analyzed 6 studies, 229 LRTC patients with 319 locally recurrent tumors were treated with RFA. The mean follow-up time of each study was ≥24 months. The pooled changes in the largest diameter and volume were 7.22 mm (95% confidence interval (CI), 6.35-8.09 mm) and 164.28 mm (95% CI, 87.78-240.77 mm), respectively; the pooled volume reduction rate was 95.03% (95% CI, 87.56-102.49%). The total complete disappearance rate after treatment was 92% (95% CI, 83-100%). The pooled decrease of serum thyroglobulin levels was 0.02 ng/ml (95% CI, -0.00-0.04 ng/ml). The pooled proportion of recurrence rate was 6% (95% CI, 0-13%). The pooled complication rate was 5% (95% CI, 0-10%). The major complications were voice change and hoarseness, only one patient developed permanent vocal cord paralysis; minor complications were cough and pain.
CONCLUSIONS
Ultrasound-guided RFA is an effective and safe treatment for LRTC based on 2-year follow-up results.

Catathrenia is a loud expiratory moan during sleep that is a social embarrassment and is sometimes confused with central apnea on polysomnography. It affects about 4% of adults, but cases are rarely referred to sleep centers. Catathrenia affects males and females, children and adults, who are usually young and thin. A "typical" catathrenia begins with a deep inhalation, followed by a long, noisy exhalation, then a short, more pronounced exhalation, followed by another deep inhalation, often accompanied by arousal. The many harmonics of the sound indicate that it is produced by the vocal cords. It is often repeated in clusters, especially during REM sleep and at the end of the night. It does not disturb the sleepers, but their neighbors, and is associated with excessive daytime sleepiness in one-third of cases. The pathophysiology and treatment of typical catathrenia are still unknown. Later, a more atypical catathrenia was described, consisting of episodes of short (2 s), regular, semi-continuous expiratory moans during NREM sleep (mainly in stages N1 and N2) and REM sleep, often in people with mild upper airway obstruction. This atypical catathrenia is more commonly reduced by positive airway pressure and mandibular advancement devices that promote vertical opening.

Meta-Analysis Review
BACKGROUND
Laryngeal leukoplakia (LL) is a white lesion with high potential of recurrence and malignant transformation. Currently, CO laser has become the primary surgical treatment for LL, and the recurrence and malignant transformation rates after treatment vary widely.
OBJECTIVE
We performed a systematic review and meta-analysis dedicated to evaluating the rates of recurrence and malignant transformation of LL lesions treated with CO laser and exploring relevant risk factors for recurrence or malignant transformation.
METHODS
Literature searches were conducted on ProQuest, PubMed, Web of Science, Ovid Medline, Embase, and Cochrane databases. Some articles identified through hand searching were included.
RESULTS
A total of 14 articles and 1462 patients were included in this review. Pooled results showed that the overall recurrence rate was 15%, and the malignant transformation rate was 3%. Subgroup analysis showed that the dysplasia grade was not a significant risk factor for the recurrence and malignant transformation of LL (P > .05).
CONCLUSIONS
The results of this systematic review and meta-analysis suggest that the CO laser is a safe and effective surgical instrument for the excision of LL, which yields low rates of recurrence and malignant transformation. The risk factors relevant to recurrence or malignant transformation remain unclear and require further investigation.

Review
OBJECTIVE
We aim to systematically review the literature addressing perioperative practices for optimal use of the CO laser in laryngeal transoral laser microsurgery (TOLMS), with a focus on safety.
DATA SOURCES
A systematic review of publications indexed in Medline, Embase, and EBM reviews-Cochrane Central Register of Controlled Trials which evaluated perioperative strategies for the use of CO laser in laryngeal TOLMS was conducted.
REVIEW METHODS
Records obtained from the search strategy were assessed for eligibility in a 2-step process by 2 independent researchers using the Covidence software.
RESULTS
Among 2143 identified records, 103 were included in this study. The majority of studies (n = 25) focused on the use of the CO laser in oncologic resection, while 20 addressed the treatment of vocal cord paralysis, 16 discussed the treatment of pediatric or congenital pathologies, 11 detailed the management of benign lesions, and 31 studies tackled other surgical indications. Strategies for safe CO TOLMS were highly heterogeneous across studies and included preoperative measures (ie, related to the environment, staff preparation, patient protection, and ventilation), intraoperative precautions (ie, protection of nontarget structures, technical considerations, topical and systemic medications), and postoperative strategies (ie, related to airway protection, oral intake, vocal rest, hospitalization duration, drug regimen, and consultant follow-up).
CONCLUSION
The results provided in this study can be used as a framework to guide the creation of laser safety protocols across institutions, guide quality improvement initiatives, the development of simulation training activities, and as a tool to facilitate resident teaching and skill assessment.

Meta-Analysis Review
Perioperative outcomes of bilateral axillo-breast approach robotic thyroidectomy (BABART) versus minimally invasive thyroidectomy (MIT): a systematic review and meta-analysis.
Minimally invasive thyroidectomy (MIT) is increasingly being used for the thyroid tumors. The comparison of bilateral axillo-breast approach robotic thyroidectomy (BABART) with other MIT has not yet led to a unified conclusion with regard to surgical outcomes. To conduct a systematic review and meta-analysis of the literature on the surgical outcomes of BABART compared with MIT. We performed a systematic search in PubMed, Web of Science, Embase and Cochrane Library database for randomized control trials (RCTs) and non-RCTs that compare BABART to MIT. The primary outcomes included perioperative, postoperative complications. The odds ratio (OR) and mean difference (MD) were applied for the comparison of dichotomous and continuous variables with 95% confidence intervals (CIs). Nine studies, comprising 3645 patients, were included in the meta-analysis. Our findings indicated that there were no significant differences in hospital stay, number of retrieved lymph nodes, recurrent laryngeal nerve (RLN) injury, and vocal cord dysfunction between BABRT and MIT. However, BABART was associated with a shorter operation time (MD = - 21.45 min, 95% CI [- 47.27, 4.38], p = 0.1) and lower rate of permanent hypoparathyroidism (OR = 0.42, 95% CI [0.20, 0.88], p = 0.02). Additionally, the MIT group had reduced postoperative pain score (MD = 0.45, 95% CI [0.02, 0.88], p = 0.04) and lower rate of hypocalcemia (OR = 2.31, 95% CI [1.04, 5.13], p = 0.04) than the BABART group. In comparison with MIT, BABART exhibits better results in terms of operative time and the rate of permanent hypoparathyroidism, with no significant difference in hospital stay, number of retrieved lymph nodes, RLN injury, and vocal cord dysfunction. However, the postoperative pain score and the rate of hypocalcemia of MIT are slightly better that of BABART.

BACKGRUOUND
Active surveillance (AS) has been introduced as a management strategy for low-risk papillary thyroid carcinoma (PTC) due to its typically indolent nature. Despite this, the widespread adoption of AS has encountered several challenges. The aim of this systematic review was to evaluate the safety of AS related to disease progression and its benefits compared with immediate surgery (IS).
METHODS
Studies related to AS in patients with low-risk PTC were searched through the Ovid MEDLINE, Embase, Cochrane Library, and KoreaMed databases. Studies on disease progression, surgical complication, quality of life (QoL), and cost-effectiveness were separately analyzed and narratively synthesized.
RESULTS
In the evaluation of disease progression, the proportions of cases with tumor growth ≥3 mm and a volume increase >50% were 2.2%-10.8% and 16.0%-25.5%, respectively. Newly detected lymph node metastasis was identified in 0.0%-1.4% of patients. No significant difference was found between IS and delayed surgery in surgical complications, including vocal cord paralysis and postoperative hypoparathyroidism. AS was associated with better QoL than IS. Studies on the cost-effectiveness of AS reported inconsistent data, but AS was more cost-effective when quality-adjusted life years were considered.
CONCLUSION
AS is an acceptable management option for patients with low-risk PTC based on the low rate of disease progression and the absence of an increased mortality risk. AS has additional benefits, including improved QoL and greater QoL-based cost-effectiveness.

Review
Direct laryngoscopy (DL) is a modality commonly used in endotracheal intubation (EI). Video laryngoscopy (VL) was introduced to further facilitate the procedure with enhancement in glottic views, which captures the video image of the vocal cords to be projected onto a screen, providing enhanced visualization. This real-time video projection aids in accurately placing the endotracheal tube (ETT) through the vocal cords. In emergency and critical care settings, both laryngoscopes are used for intubations. This study assesses the efficacy of both modalities by comparing success rates in first-attempt tracheal intubation in critically ill patients. PubMed, EMBASE, and Scopus were searched and all randomized controlled trials (RCTs) and observational studies until 2023 were included. Studies included patients in critical care settings undergoing EI under the guidance of either DL or VL. The primary outcome was the first attempt at successful tracheal intubation. The secondary outcomes assessed the comparative safety of DL and VL by comparing the rates of severe hypoxemia, severe hypotension, and cardiac arrest occurring during each modality. P-values were considered of statistical significance if below 0.05. Statistical analysis was performed using RevMan v5.4 (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark). The results were displayed in the form of forest plots. A total of eight studies were included with a total of 5348 patients, with 1780 in the DL group and 3568 in the VL group. Analysis revealed that in emergency situations, the success rate of intubation on the first attempt was significantly higher for VL than DL [81.5% vs 68%; RR= 1.19; 95% CI: 1.10, 1.29; p <0.00001; I2=70%]. There was no significant correlation between VL and severe hypoxemia [13.4% vs 11.6%; RR= 0.99; 95% CI: 0.74, 1.33; p =0.97; I2=46%], severe hypotension [6.09% vs 4.78%; RR:1.19; 95% CI: 0.83, 1.72; p =0.35, I2-15%], and cardiac arrest, [0.8% vs 0.4%; RR= 1.17; 95% CI: 0.37, 3.70]; p =0.79; I2=0%]. Our meta-analysis confirmed that VL has a higher success rate for first-pass intubation than DL. Furthermore, our analysis has shown no significant evidence linking VL to any adverse events.

Systematic Review and Meta-Analysis of Randomized Controlled Trials (RCTs) Revealing the Future of Airway Management: Video Laryngoscopy vs. Macintosh Laryngoscopy for Enhanced Clinical Outcomes.
Since the 1940s, Macintosh laryngoscopy (Mac laryngoscopy) has been the gold standard for tracheal intubation, offering visualization of the glottis entrance. However, recent years have witnessed the emergence of various video laryngoscopy (VL) techniques. This systematic review and meta-analysis aims to assess the clinical outcomes of VL Mac laryngoscopy in an elective setting. We comprehensively searched five medical databases - PubMed, EMBASE, Medline, Cochrane Library, and Web of Science. All the databases were last searched in January 2023. We only included studies with full texts comparing VL to Mac laryngoscopy clinical outcomes. Studies were excluded if they were non-full text or non-randomized controlled trials (RCTs) and did not compare VL to Mac laryngoscopy. We extracted data comprising author names, publication year, key study outcomes (first-attempt intubation success rate, Cormack and Lehane grade, hypoxia incidence, and glottis view quality), video laryngoscope types, and sample sizes of both VL and Mac laryngoscopy groups. The Cochrane risk of bias tool was used to assess the risk of bias in the included studies. Statistical analysis was performed using Review Manager (RevMan, version 5.4; Cochrane Collaboration, London, UK), presenting results as odds ratio (OR) and risk ratios (RR) at a 95% confidence interval (CI). This facilitated the identification of relevant and appropriate studies of our analysis. The search produced 19 studies that were included in this review. The evaluated sample size ranges from 40 to 802, with 3,238 participants. The rate of success at the first attempt in the use of VL was 1,558/1,890 (82.43%), while the success rate for Mac laryngoscopy was 982/1,348 (72.85%; OR: 1.98 (1.25, 3.12)) at a 95% confidence interval. Pooled analysis indicated no significant difference for hypoxia concerning the type of device used RR (random effects: 1.02; 95% CI: 0.80-1.29). A video laryngoscope had a higher likelihood of visualizing the vocal cords categorized as category 1 in the Cormack-Lehane system of classification (RR: 2.45; 95% CI: 1.43-4.21). Additionally, considerably better glottis views were attained during VL than Mac laryngoscopy (OR: 1.77; 95% CI: 1.19-2.62). In elective tracheal intubation, VL demonstrates superior first-attempt success rates, offers improved glottis visualization, and reduces instances where the glottis cannot be viewed compared to Mac laryngoscopy.

Brazilian Journal of Otorhinolaryngology 2024To assess the safety and effectiveness of bilateral axillo-breast approach robotic thyroidectomy in thyroid tumor. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVES
To assess the safety and effectiveness of bilateral axillo-breast approach robotic thyroidectomy in thyroid tumor.
METHODS
Bilateral axillo-breast approach robotic thyroidectomy and other approaches (open thyroidectomy, transoral robotic thyroidectomy, and bilateral axillo-breast approach endoscopic thyroidectomy) were compared in studies from 6 databases.
RESULTS
Twenty-two studies (8830 individuals) were included. Bilateral axillo-breast approach robotic thyroidectomy had longer operation time, greater cosmetic satisfaction, and reduced transient hypoparathyroidism than conventional open thyroidectomy. Compared to bilateral axillo-breast approach endoscopic thyroidectomy, bilateral axillo-breast approach robotic thyroidectomy had greater amount of drainage, lower chances of transient vocal cord palsy and permanent hypothyroidism, and better surgical completeness (postopertive thyroblobulin level and lymph node removal). Bilateral axillo-breast approach robotic thyroidectomy induced greater postoperative drainage and greater patient dissatisfaction than transoral robotic thyroidectomy.
CONCLUSION
Bilateral axillo-breast approach robotic thyroidectomy is inferior to transoral robotic thyroidectomy in drainage and cosmetic satisfaction but superior to bilateral axillo-breast approach endoscopic thyroidectomy in surgical performance. Its operation time is longer, but its cosmetic satisfaction is higher than open thyroidectomy.
