BACKGROUND: Tracheal, bronchus, and lung cancer (TBL) is a major cause of mortality and top contributor to productivity loss in large emerging economies such as the BRICS (Brazil, Russia, India, China, and South Africa). We examined the time trends of TBL mortality across the BRICS to better understand the disease burden in these countries and inform public health and healthcare resource allocation. METHODS: TBL mortality-related data between 1990 and 2019 were obtained from the Global Burden of Disease Study 2019 and analyzed using age-period-cohort models. Net drift (local drift) was used to describe the expected age-adjusted TBL mortality rate over time overall (each age group); the longitudinal age curve was used to reflect the age effect; the period rate ratios (RRs) were used to reflect the period effect; and the cohort RR was used to reflect the cohort effect. RESULTS: In 2019, there were 958.3 thousand TBL deaths across the BRICS, representing 46.9% of the global TBL deaths. From 1990 to 2019, the age-standardized mortality rate (ASMR) of TBL decreased in Russia, Brazil, and South Africa while increased in China and India, with the largest reduction reported in Russia (-29.6%) and the largest increase in China (+22.4%). India showed an overall increase (+15.7%) in TBL mortality but the mortality risk decreased among individuals born after 1990 (men) and 1995 (women). Although South Africa and Brazil experienced an overall decline in TBL mortality, their recent birth cohorts, such as Brazilian individuals born after 1985 (men) and 1980 (women), and South African men born after 1995, had an increasing TBL mortality risk. China has experienced an overall increase in TBL mortality, with the mortality risk rising among individuals born after 1995 for both men and women. Russia, which had the highest TBL mortality among the BRICS countries in 1990, has demonstrated significant improvement over the past three decades. CONCLUSIONS Over the past 30 years, the BRICS accounted for an increasing proportion of global TBL mortality. TBL mortality increased in older women in all the BRICS countries except Russia. Among the recent birth cohort, the risk of TBL mortality increased in Brazil, China, and South Africa. More effective efforts are needed in the BRICS to reduce the burden of TBL and help achieve the United Nation's Sustainable Development Goals.

Objective: To analyze the clinical characteristics and complications of esophageal foreign bodies of button battery ingestion in children. Methods: A retrospective descriptive study included 83 children who were hospitalized in our hospital on account of button battery ingestion from January 2011 to December 2021. There were 50 males (60.2%) and 33 females (39.8%). The age ranged from 7.6 months to one month off 10 years, with a median age of 18 months. The data of patient demographics and time from ingestion to admission, location, symptoms, management, complications, and follow-up outcome were recorded. SPSS17.0 software was used for statistical analysis. Results: Seventy-two children (86.7%) were younger than 3 years old. The time from ingestion to admission ranged from 1 h to 2 months, with a median time of 8 h. Among the 63 children who were first diagnosed in our hospital, the most common clinical symptoms were nausea and vomiting (32 cases, 50.8%), dysphagia (31 cases, 49.2%), salivation (11 cases, 17.5%) and fever (10 cases, 15.9%). Seventy-three of 83 cases had complete preoperative diagnostic tests, and 55 cases (75.3%) were diagnosed by X-ray. In 56 cases (76.7%), the foreign badies were impacted in the upper third of esophagus. In 72 cases (86.7%), the foreign badies were removed by rigid esophagoscopy. 23 (27.7%) had serious complications, including tracheoesophageal fistula in 15 cases(TEF;65.2%), vocal cord paralysis (VCP;34.8%) in 8 cases, esophageal perforation in 3 cases (EP;13.0%), hemorrhage in 3 cases(13.0%), mediastinitis in 3 cases (13%), and periesophageal abscess in 1 case (4.3%). There were significant differences in the exposure time of foreign bodies and unwitnessed ingestion by guardians in the complications group (P<0.05). 2 cases died (2.4%)respectively due to arterial esophageal fistula bleeding and respiratory failure caused by stent displacement during the treatment of tracheoesophageal fistula. Conclusion: Accidental button battery ingestion can be life-threatening. and it mostly happens in children under 3 years old. Serious complications may happen cause of non-specific clinical manifestations and unwitnessed ingestions. Anterior and lateral chest X-ray is the first examination choice. Tracheoesophageal fistula is the most common serious complication.

OBJECTIVES: To study the role of bronchoscopy in slide tracheoplasty. METHODS: A retrospective analysis was conducted on the diagnosis and treatment of four children with tracheal stenosis admitted to Hunan Provincial People's Hospital from 2017 to 2020. The role of bronchoscopy was summarized in the preoperative evaluation, intraoperative positioning and measurement, and postoperative wound evaluation and treatment during slide tracheoplasty. RESULTS: Bronchoscopy evaluation before slide tracheoplasty showed that 3 of the 4 children had complete trachea rings, 2 had pulmonary artery sling, and 2 had multiple stenosis. Slide tracheoplasty was performed in the hospital on 3 children, and the midpoint of the stenosis segment was judged under bronchoscopy, and the length of the stenosis segment was measured, which assisted in the resection of the stenosis segment of the trachea. The pathogens were identified by lavage after the surgery. One child who developed scar traction 9 months after slide tracheoplasty in another hospital was improved by interventional treatment under bronchoscopy. Mucosal changes were found under bronchoscopy in 2 children 4 days after surgery, and the treatment plan was adjusted. One month after surgery, 2 children had granulation hyperplasia, which was improved by cryotherapy under bronchoscopy. One child abandoned treatment due to anastomotic necrosis and died. Three survivors were followed up for over 6 months with good prognosis, but all had tracheobronchial malacia. CONCLUSIONS Bronchoscopy can be used for the management of slide tracheoplasty in children with tracheal stenosis, which is helpful to postoperative rehabilitation and follow-up.

Objective: To examine the outcomes of Slide tracheoplasty for the children with severe congenital tracheal stenosis received previous repeated balloon dilatation or metal stent placement under endoscopy. Methods: A retrospective study was conducted in 9 children with congenital tracheal stenosis undergoing previous interventional therapy under tracheoscopy and later received Slide tracheoplasty due to obvious respiratory symptoms at Department of Cardiac Surgery, Qilu Children's Hospital of Shandong University between February 2017 and July 2021. There were 7 males and 2 females with a median age at operation of 72.4 months (range: 13.3 to 98.9 months), and the median weight was 19.0 kg (range: 9.0 to 33.0 kg). Among the 9 patients, 2 patients began to receive repeated balloon dilatation (more than 3 times) 17.8 and 51.8 months ago respectively. One patient received metal stents placement into the trachea for 4 days and the other 6 children for median 56.8 months (range: 21.6 to 74.2 months). Complete tracheal cartilage rings and long segmental stenosis were present. in all 9 children. Operative details and outcome measures, including the need for endoscopic airway intervention and mortality, were collected. Results: Slide tracheoplasty was performed in all cases. Two patients with repeated balloon dilatation had different thickness of tracheal wall, local scar hyperplasia and irregular lumen. Among them, 1 case had obvious local calcification of tracheal wall, which was difficult to suture. The metal stent in one patient with short time of placement was completely removed. However, only part of the metal stents could be removed due to the long placement time in the other 6 cases. There was no operative death in the 9 children. The median postoperative tracheal intubation time was 25.3 hours (range: 17.4 to 74.5 hours). A silicone stent was placed in the trachea of 1 child due to obvious respiratory symptoms. Follow-up of median 11 months (range: 1 to 23 months) showed that no death occurred after discharge and all children had basically normal activity tolerance with no obvious respiratory symptoms. Conclusions: Slide tracheoplasty is feasible for children undergoing prior balloon dilatation or metal stents placement. Previously repeated balloon dilatation or metal stent placement under endoscopy increased the difficulty of slide tracheoplasty, the metal stent could not be completely removed after a long time.

Objective: To compare the accuracy of the centerline extracted based on CT 3D reconstruction and conventional CT 3D reconstruction in measuring the length and degree of laryngotracheal stenosis. Methods: A retrospective analysis was performed on 35 patients with laryngotracheal stenosis (including 19 cases without tracheotomy and 16 cases with tracheotomy) treated in the Department of Otorhinolaryngology Head and Neck Surgery of the First Affiliated Hospital of Guangxi Medical University from March 2006 to March 2016, including 20 males and 15 females, whose ages ranged from 1 to 73 years, with a median age of 40.5 years. And CT data of 20 normal subjects were included in the same period, including 10 males and 10 females, whose ages ranged from 20 to 63 years, with a median age of 37.0 years. The continuous cross-sectional area of the airway perpendicular to the centerline was obtained by Mimics software. The area was compared with the discontinuous cross-sectional areas reconstructed by conventional CT 3D reconstruction software advantage workstation, also the length of cervical trachea, the length of stenosis, and the minimum airway area were compared. Multi-factor linear stepwise regression method was used to analyze the factors influencing the measuring difference between the two methods. Three patients with laryngotracheal stenosis were selected, and the measured stenosis length was compared with the surgical specimens to evaluate the accuracy of the two methods. SPSS 26.0 software was used for statistical analysis. Results: In normal people, the areas of thyroid cartilage notch, glottis, inferio thyroid cartilage margin, inferio cricoid cartilage margin, and suprasternal notch planes measured by Mimics centerline method were smaller than those measured by conventional CT 3D reconstruction (t _{thyroid cartilage notch}=4.685, t_glottis=3.791, t_{lower thyroid cartilage margin}=5.621, t_{lower cricoid cartilage margin}=6.312, t_{suprasternal notch plane}=6.436, P<0.05). And the airway length measured by Mimics centerline method from the inferior thyroid cartilage to the superior sternal notch was longer (t=9.79, P<0.001). In laryngotracheal stenosis, in the non-tracheotomy group, the minimum airway area measured by Mimics centerline method was smaller and the stenosis length was longer than those measured by the conventional CT 3D reconstruction, and the difference was statistically significant (t_{minimum airway area}=2.562, t_{stenosis length}=5.240, P<0.05). In the tracheotomy group, the stenosis length measured by Mimics centerline method was longer than that measured by conventional CT 3D reconstruction, and the difference was statistically significant (t_{stenosis length}=2.854, P<0.05). Multi-factor linear regression analysis showed that different CT thickness had a statistically significant effect on the difference in the length of stenosis measured by the two methods (b=-5.370, t=-3.306, P=0.004), and different tracheal forward angle had a statistically significant effect on the difference in the minimum airway area measured by the two methods (b=-0.419, t=-2.208, P=0.04). The difference between the measured length of the Mimics centerline method and the intraoperative specimens was less than 0.5 mm. Conclusion: The centerline extracted based on CT 3D reconstruction can precisely reflect the laryngotracheal morphology and measure laryngotracheal stenosis more accurately.

OBJECTIVE: To summarize the experience in the application of muscle relaxants in the perioperative period in neonates with congenital esophageal atresia-tracheoesophageal fistula (EA-TEF). METHODS: A retrospective analysis was performed on the medical data of 58 previously untreated neonates with EA-TEF who were treated in the Neonatal Center of Beijing Children's Hospital, Capital Medical University from 2017 to 2019. The incidence rate of anastomotic leak was compared between the neonates receiving muscle relaxants for different durations after surgery (≤ 5 days and > 5 days). The correlation between the duration of postoperative use of muscle relaxants and the duration of mechanical ventilation was evaluated. RESULTS: Among the 58 neonates with EA-TEF, 44 underwent surgery, among whom 35 with type III EA-TEF underwent thoracoscopic surgery. Among these 35 neonates, 30 (86%) received muscle relaxants after surgery, with a median duration of 4.75 days, and 6 (18%) experienced anastomotic leak. There was no significant difference in the incidence rate of anastomosis leak between the ≤ 5 days and > 5 days groups ( CONCLUSIONS Prolonged use of muscle relaxants after surgery cannot significantly reduce the incidence of anastomotic leak, but can prolong the duration of invasive mechanical ventilation in neonates with EA-TEF. Therefore, prolonged use of muscle relaxants is not recommended after surgery.
