Conservative management of a rare case of post thyroidectomy tracheal injury with coagulation abnormalities.

Background: Tracheal injury is a rare but potentially serious acute complication of endotracheal intubation. Very few cases of tracheal injury associated with coagulation abnormalities have been reported in the literature. We present a rare case of a patient presenting with tracheal injury in combination with coagulation abnormalities following thyroidectomy. Case presentation: A 58-year-old woman with a history of postoperative chemotherapy for breast cancer, gastric polyps, multiple colonic polyps, esophageal papillary adenomas, and thyroid adenomas presented with dyspnea following 10 ml hemoptysis on the third day after thyroidectomy; she was admitted to the intensive care unit and underwent tracheal intubation for maintaining the airway. Subsequent bronchoscopy revealed a nodular red neoplasm 5-cm from the carina in the trachea obstructing part of the lumen, with a small amount of fresh hemorrhage on the surface. Tracheal injury was considered the preliminary diagnosis. Fiberoptic bronchoscope guided tracheal intubation helped prevent rupture of the tumor, and the cannula was properly inflated to arrest the bleeding while blocking the lower part of the trachea. An emergency surgical evacuation of the cervical hematoma was performed for managing postoperative bleeding. The patient demonstrated persistent pancytopenia despite frequent transfusions. Laboratory examination results revealed abnormal coagulation parameters, anemia, and hepatic dysfunction. Following a multidisciplinary team discussion, pituitrin for hemostasis, tranexamic acid for strengthening hemostasis treatment, and nutritional support and anti-infection treatment were initiated. Endotracheal tube cuff inflation was performed to compress the bleeding site. Complete resolution of the subcutaneous hematoma was observed nine days after the tracheal injury; bronchoscopy revealed residual ecchymosis in the airway hematoma with no evidence of obstruction. Conclusion: Conservative management of tracheal injury limited to the mucosa or submucosa without significant amount of active bleeding using endotracheal intubation is considered a practical and effective approach. Successful management was ensured by appropriate clinical suspicion, early multidisciplinary team discussion, and prompt diagnosis and interventions.

Major depressive disorder and irritable bowel syndrome risk: A Mendelian randomization study.

BACKGROUND: Previous studies have revealed a connection between major depressive disorder (MDD) and irritable bowel syndrome (IBS), but it remains obscure if the two diseases are related causally. Mendelian randomization was utilized in this investigation to ascertain whether MDD contributed to the emergence of IBS. METHODS: To examine possible connections between MDD and IBS, we used two-sample Mendelian randomization (MR) utilizing summary data from genome-wide association studies (GWAS). The Psychiatric Genomics Consortium (PGC) provided information on genetic associations with MDD (cases: 135,458; controls: 344,901). The Medical Research Council Integrative Epidemiology Unit (MRC-IEU) provided information on genetic associations with IBS (cases:10,939; controls:451,994). Inverse Variance Weighted (main analyses), MR-Egger regression, Weighted mode, and Weighted Median were the four MR methods used in this investigation. In addition, we also performed multiplicity and heterogeneity analyses to eliminate possible biases. RESULTS: In the standard Inverse Variance Weighting (IVW) method, an increased risk of IBS was linked to a genetic susceptibility to MDD (OR: 1.01; 95% CI: 1.006 to 1.014, p = 1.02E-07). In addition, neither significant heterogeneity (IVW Q = 24.80, p = 0.73) nor horizontal pleiotropy (MR Egger p = 0.17; MRPRESSO p = 0.54) were detected in this MR analysis. The bidirectional analysis, however, did not show a genetic link between IBD and MDD (p steiger <0.01). CONCLUSION: A direct causal relationship between MDD and IBS was revealed by Mendelian randomization study, which contributes to the effective clinical management of both diseases.

Placement of bronchial occluder outside the tracheal tube in a patient combined with airway compression undergoing mediastinal tumors resection: a case report.

BACKGROUND: Mediastinal tumors pose a challenging respiratory and circulatory management during anesthesia procedures, there is a risk of circulatory collapse or complete airway obstruction, which in severe cases can lead to cardiac arrest. We reported a case of anesthetic management using a bronchial blocker placed outside the tracheal tube. In this case report, the patient's trachea was so severely compressed that the airway was extremely narrow, only 4 mm at its narrowest point. By reporting the anesthetic management of this patient, we intend to provide an unusual approach for airway management. CASE PRESENTATION: A 52-year-old male patient was admitted to the hospital due to cough and expectoration for one year. Additionally, the patient experienced chest tightness and asthma after physical activity. The enhanced computed tomography revealed there existed an irregular soft tissue mass in the right upper mediastinum, which significantly compressed the trachea and esophagus. The results of the mediastinal puncture pathology showed the presence of mesenchymal tumors. According to the results above, the patient was diagnosed with a mediastinal tumor and scheduled to undergo tumor resection under general anesthesia. We used a bronchial occluder outside the tracheal tube for general anesthesia. After surgery, the patient received thorough treatment and was subsequently discharged from the hospital. CONCLUSION: In patients with severe airway compression from a mediastinal tumor airway compression, positioning a bronchial occluder externally to the tracheal tube is an effective method of airway management. However, we still need more clinical practice to help the process become more standardized.

Anesthetic management of thyroid carcinoma invading the upper tracheal segment: A case report.

INTRODUCTION AND IMPORTANCE: Intratracheal tumors account for approximately 0.2 % of respiratory tumors, including primary and secondary tumors. Secondary tumors of the upper trachea are most commonly derived from advanced thyroid cancer. Surgical resection is currently the general curative modality for thyroid cancer with tracheal invasion. Patients with tracheal tumors invading and protruding into the lumen may have reduced oxygen reserve capacity, leading to a shorter safe window for general anesthesia induction. Establishing an appropriate artificial airway is essential to ensure intraoperative safety for these patients. Here, we report a case of tracheal tumor caused by differentiated papillary thyroid carcinoma invading the upper segment of the trachea and the non-conventional approach used for intraoperative airway management without traditional endotracheal intubation. PRESENTATION OF CASE: A 59-year-old female presented with bilateral neck masses and hemoptysis. The CT scan revealed suspicious malignant thyroid nodules, and tracheoscopy showed an approximately 50 % obstruction of the tracheal lumen. The patient's physical examination and biochemical examination showed no significant abnormalities. Based on imaging studies and pre-anesthetic assessment, a multidisciplinary team decided against performing endotracheal intubation in the patient due to the risk of tumor bleeding during the procedure. Instead, they opted for a modified endotracheal tube and the insertion of a laryngeal mask airway (LMA). The anesthesia induction and maintenance proceeded smoothly, with stable intraoperative hemodynamics. The tumor was successfully resected and tracheal anastomosis was performed without any complications. CLINICAL DISCUSSION: The strategy adroitly evades the risk of bleeding and dislodgement due to tumor contact during the intubation process. In this case report, the anesthetic highlight is the employment of a reverse insertion technique for endotracheal intubation, facilitated by a sterile suction catheter and complemented by an innovative modification to the tracheal tube. CONCLUSION: For patients with thyroid cancer invading the upper segment of the trachea, and in whom rapid induction anesthesia is anticipated not to cause tumor collapse, the use of laryngeal mask airway combined with modified tracheal tube mechanical ventilation is both safe and feasible.

Down-regulating lncRNA KCNQ1OT1 relieves type II alveolar epithelial cell apoptosis during one-lung ventilation via modulating miR-129-5p/HMGB1 axis induced pulmonary endothelial glycocalyx.

OBJECTIVE: Endothelial glycocalyx (EG) maintains vascular homeostasis and is destroyed after one-lung ventilation (OLV)-induced lung injury. Long noncoding RNAs (lncRNAs) are critically involved in various lung injuries. This study aimed to investigate the role and regulatory mechanism of KCNQ1 overlapping transcript 1 (KCNQ1OT1) in OLV-induced lung injury and LPS-induced type II alveolar epithelial cell (AECII) apoptosis. METHODS: The rat OLV model was established, and the effects of KCNQ1OT1 on OLV-induced ALI in vivo were explored. Bax and Caspase-3 expression in rat lung tissues was measured by immunochemistry (IHC). AECIIs were isolated from rat lungs and treated with LPS or normal saline (control) for in vitro analysis. The expression of KCNQ1OT1, miR-129-5p, and HMGB1 was measured by quantitative real-time PCR (qRT-PCR) or Western blot (WB). Cell proliferation and apoptosis were examined by 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di- phenytetrazoliumromide (MTT) and flow cytometry. The downstream targets of KCNQ1OT1 were predicted by bioinformatics, and the binding relationship between KCNQ1OT1 and miR-129-3p was verified by dual-luciferase reporter assays. The potential target of miR-129-5p was further explored on the Targetscan website and revealed to target HMGB1. Enzyme-linked immunosorbent assay (ELISA) or WB was adopted to determine the levels of IL-1ß, TNF-α, MDA, SOD, heparanase (HPA), matrix metalloproteinase 9 (MMP9), heparan sulfate (HS) and syndecan-1 (SDC-1). RESULTS: KCNQ1OT1 and HMGB1 were up-regulated during OLV-induced lung injury, and their expression was positively correlated. KCNQ1OT1 knockdown reduced OLV-induced pulmonary edema and lung epithelial cell apoptosis, increased vascular permeability, reduced IL-1ß, TNF-α, MDA, and SOD levels and glycocalyx markers by targeting miR-129-5p or upregulating HMGB1. Overexpressing KCNQ1OT1 promoted cell apoptosis, reduced cell proliferation, aggravated inflammation and oxidative stress, and up-regulated HMGB1, HPA and MMP9 in LPS-treated AECIIs, while the HMGB1 silencing showed the opposite effects. MiR-129-5p mimics partially eliminated the KCNQ1OT1-induced effects, while recombinant HMGB1 restored the effects of miR-129-5p overexpression on AECIIs. Additionally, KCNQ1OT1 was demonstrated to promote the activation of the p38 MAPK/Akt/ERK signaling pathways in AECIIs via HMGB1. CONCLUSION: KCNQ1OT1 knockdown alleviated AECII apoptosis and EG damage during OLV by targeting miR-129-5p/HMGB1 to inactivate the p38 MAPK/Akt/ERK signaling. The findings of our study might deepen our understanding of the molecular basis in OLV-induced lung injury and provide clues for the targeted disease management.

Effects of Press Needling combined with general anesthesia on postoperative analgesia in thoracoscopic pulmonary resection for lung cancer: A randomized, single-blind, controlled trial.

OBJECTIVES: To investigate the effects of press needle therapy on postoperative analgesia and other relevant complications in patients undergoing thoracoscopic pulmonary resection. DESIGN: randomized, single-blind, controlled trial SETTING: Teaching hospitals affiliated with universities. INTERVENTIONS: Eighty-six patients were randomized into: the Acu group (press-needle group) and the control group MAIN OUTCOME MEASURES: Pain levels 24, 48, and three months after surgery were measured using the numeric rating scale (NRS). Perioperative hemodynamics, total and effective pressing numbers of patient-controlled intravenous analgesia (PCIA), and incidence of postoperative pulmonary complications were recorded. Peripheral blood samples were collected to measure the levels of inflammatory mediators RESULTS: Acu group had significantly lower NRS scores at 24 and 48 h after operation (NRS scores on movement at 24 h after surgery: Acu vs. Control, 3 (2,3) vs. 3 (3,5), Z = -3.393, P < 0.01 and NRS scores on movement at 48 h after surgery: 2 (1,3) vs. 3 (2,5), Z = -3.641, P < 0.01), lower number of PCIA attempts and effective rates (mean total pressing numbers: 4(2,8) vs. 6(3,19), Z = -1.994, P = 0.046 and mean effective pressing numbers: 3(2,8) vs. 6(3,16), Z = -2.116, P = 0.034). The Acu group had significantly reduced IL-1 (14.52 ± 3.84 vs. 16.36 ± 3.30, mean difference (MD): - 1.85, 95% confidence interval (CI): - 3.46, - 0.23, P = 0.026), HIF-1α (10.15 ± 1.71 vs. 10.96 ± 1.73, MD: -0.81, 95% CI: -1.59, -0.04, P = 0.040) and the incidence of pulmonary complications after surgery. CONCLUSION: Press needles are a non-invasive and feasible adjunctive intervention for postoperative analgesic management in patients undergoing thoracoscopic pulmonary resection.

People conform to social norms when gambling with lives or money.

Many consider moral decisions to follow an internal "moral compass", resistant to social pressures. Here we examine how social influence shapes moral decisions under risk, and how it operates in different decision contexts. We employed an adapted Asian Disease Paradigm where participants chose between certain losses/gains and probabilistic losses/gains in a series of moral (lives) or financial (money) decisions. We assessed participants' own risk preferences before and after exposing them to social norms that are generally risk-averse or risk-seeking. Our results showed that participants robustly shifted their own choices towards the observed risk preferences. This conformity holds even after a re-testing in three days. Interestingly, in the monetary domain, risk-averse norms have more influence on choices in the loss frame, whereas risk-seeking norms have more influence in the gain frame, presumably because norms that contradict default behavior are most informative. In the moral domain, risk-averse as opposed to risk-seeking norms are more effective in the loss frame but in the gain frame different norms are equally effective. Taken together, our results demonstrate conformity in risk preferences across contexts and highlight unique features of decisions and conformity in moral and monetary domains.

A Study of Blended Learning Using the Smart Class Teaching Module on Psychosocial Dysfunction Course During the Training of Undergraduate Occupational Therapy Students in China.

BACKGROUND Online blended learning, also known as "smart classes", has benefits when compared with traditional teaching methods that use books and lectures. This study aimed to compare the use of the Smart Class teaching module with traditional teaching on the topic of psychosocial dysfunction during the training of undergraduate occupational therapy (OT) students in China. MATERIAL AND METHODS We recruited Grade 2017 OT students as the Smart Class teaching module group and Grade 2016 OT students as the Traditional Class teaching module group to participate in the study. The objective evaluation (assignment score, practical exam score, written exam score, and final score) and subjective evaluation (data from student questionnaires and information from interviews with the lead teacher and assistant teachers) were performed in both groups. RESULTS No significant difference was found in the final scores (P=0.874) and students' questionnaire results between the 2 groups. However, data from the student questionnaires and teacher interviews indicated a preference for combining the Smart Class teaching module and the Traditional Class teaching module. CONCLUSIONS The advantage of the Smart Class teaching module is that it can effectively integrate excellent teaching resources across geographical restrictions and it is conducive to promoting independent learning for students and all-around supervision for teaching. The Smart Class teaching module was comparable to traditional teaching methods for the training of undergraduate OT students in China, but was preferred by the students.
