Benralizumab efficacy and safety in severe asthma: A randomized trial in Asia.

BACKGROUND: Benralizumab is indicated as add-on therapy in patients with uncontrolled, severe eosinophilic asthma; it has not yet been evaluated in a large Asian population with asthma in a clinical trial. OBJECTIVE: To evaluate the efficacy and safety of benralizumab in patients with severe asthma in Asia. METHODS: MIRACLE (NCT03186209) was a randomized, Phase 3 study in China, South Korea, and the Philippines. Patients aged 12-75 years with severe asthma receiving medium-to-high-dose inhaled corticosteroid/long-acting ß2-agonists, stratified (2:1) by baseline blood eosinophil count (bEOS) (≥300/µL; <300/µL), were randomized (1:1) to benralizumab 30 mg or placebo. Endpoints included annual asthma exacerbation rate (AAER; primary endpoint), change from baseline at Week 48 in pre-bronchodilator (BD) forced expiratory volume in 1 second (pre-BD FEV1) and total asthma symptom score (TASS). Safety was evaluated ≤ Week 56. RESULTS: Of 695 patients randomized, 473 had baseline bEOS ≥300/µL (benralizumab n = 236; placebo n = 237). In this population, benralizumab significantly reduced AAER by 74% (rate ratio 0.26 [95% CI 0.19, 0.36], p < 0.0001) and significantly improved pre-BD FEV1 (least squares difference [LSD] 0.25 L [95% CI 0.17, 0.34], p < 0.0001) and TASS (LSD -0.25 [-0.45, -0.05], p = 0.0126) versus placebo. In patients with baseline bEOS <300/µL, there were numerical improvements in AAER, pre-BD FEV1, and TASS with benralizumab versus placebo. The frequency of adverse events was similar for benralizumab (76%) and placebo (80%) in the overall population. CONCLUSIONS: MIRACLE data reinforces the efficacy and safety of benralizumab for severe eosinophilic asthma in an Asian population, consistent with the global Phase 3 results.

Objective:To retrospectively analyze the feasibility of undergoing day surgery at 3rd week after infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in children.Methods:The clinical data from children who underwent day surgery from November 1, 2022 to February 28, 2023, with operation time ≤1 h, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, regardless of gender, aged≤14 yr, with body mass index of 10-30 kg/m 2, were divided into SARS-CoV-2 group and control group according to whether the children had been infected with the SARS-CoV-2. The main outcome measure was the incidence of respiratory system-related complications within 30 days after surgery. Secondary outcome measures included the rate of unplanned ventilation, delayed discharge and secondary admission within 30 days after surgery. Preoperative creatine kinase isoenzyme (CK-MB), aspartate aminotransferase (AST), alanine aminotransferase (ALT), hemoglobin (Hb), white blood cell count, C-reactive protein (CRP) level, grade of oropharyngeal mucosa inflammation, operation time, emergence time, intraoperative respiratory depression, laryngeal spasm, hypoxemia, hypotension, incidence of sinus bradycardia and rate of additional rescue drugs were recorded. Results:There were 337 cases in SARS-CoV-2 group and 1 396 cases in control group. Compared with control group, CK-MB concentrations were significantly increased, and the Hb concentration was decreased before surgery in SARS-CoV-2 group ( P<0.05). There were no statistically significant differences in the incidence of respiratory system-related complications, unplanned ventilation, delayed discharge and rate of postoperative secondary admission, preoperative AST and ALT concentrations, white blood cell count, CRP concentrations, grade of oropharyngeal mucosa inflammation, operation time, intraoperative respiratory depression, laryngeal spasm, hypoxemia, hypotension, incidence of sinus bradycardia, rate of additional rescue drugs and emergence time between the two groups ( P>0.05). Conclusions:Feasibility of undergoing day surgery is good at the third week after being infected with the SARS-CoV-2 in children.

Lymphocyte subpopulations and interleukin-6 levels in patients with viral pneumonia and their relationship with prognosis / 中国医师杂志

Objective:To explore the relationship between peripheral blood lymphocyte subsets, interleukin-6 (IL-6) levels, and prognosis in patients with viral pneumonia.Methods:A total of 100 patients with viral pneumonia admitted to the Emergency Department of the Chuiyangliu Hospital Affiliated to Tsinghua University from December 2021 to November 2023 were selected and divided into a survival group and a death group. 20 healthy individuals who underwent physical examinations during the same period were selected as the control group. General information of the patients was collected, and peripheral blood lymphocyte subsets and related cytokine IL-6 were detected. Differences in peripheral blood lymphocyte subsets and IL-6 levels among different groups were analyzed, And multiple logistic regression was used to analyze the influencing factors of viral pneumonia disease and death.Results:The proportion of death group with diabetes was significantly higher than that of survival group ( P<0.05). The mortality of patients with diabetes was higher than that of patients without diabetes [60.7%(17/28) vs 12.5%(9/72), P<0.05]. The total number of peripheral blood T lymphocytes, helper/inducible T lymphocytes (Th), CD4 + /CD8 + ratio, B lymphocyte count, and natural killer (NK) cells in patients with viral pneumonia were significantly lower than those in the healthy control group (all P<0.05), and the level of IL-6 was significantly higher than that in the healthy control group ( P<0.05); The total number of peripheral blood T lymphocytes, Th cells, CD4 + /CD8 + ratio, B lymphocyte count, and NK cells in the death group were significantly lower than those in the survival group (all P<0.05), and the level of IL-6 was significantly higher than that in the survival group ( P<0.05). The results of multivariate logistic regression analysis showed that T lymphocyte subsets and IL-6 were all influencing factors for the disease and death of viral pneumonia (all P<0.05). Conclusions:The mortality of viral pneumonia patients with diabetes increased; The absolute number of lymphocyte subsets decreases and the level of IL6 increases in patients with viral pneumonia; The difference in changes between the death group and the survival group is more significant; Early detection of peripheral blood lymphocyte subsets and IL6 levels is beneficial for evaluating the prognosis of patients with viral pneumonia and has certain guiding value for clinical practice.

Endoscopic resection of type D trigeminal schwannoma through nasal sinus approach / 中华外科杂志

Objective: To examine the feasibility and surgical approach of removing type D trigeminal schwannoma through nasal cavity and nasal sinus under endoscope. Methods: Eleven patients with trigeminal schwannoma who were treated in the Department of Otorhinolaryngology, Qilu Hospital of Shandong University from December 2014 to August 2021 were analyzed retrospectively in this study. There were 7 males and 4 females, aged (47.5±13.5) years (range: 12 to 64 years). The neoplasm involved the pterygopalatine fossa, infratemporal fossa, ethmoidal sinus, sphenoid sinus, cavernous sinus, and middle cranial fossa. The size of tumors were between 1.6 cm×2.0 cm×2.0 cm and 5.7 cm×6.0 cm×6.0 cm. Under general anesthesia, the tumors were resected through the transpterygoid approach in 4 cases, through the prelacrimal recess approach in 4 cases, through the extended prelacrimal recess approach in 2 cases, and through the endoscopic medial maxillectomy approach in 1 case. The nasal endoscopy and imaging examination were conducted to detect whether neoplasm recurred or not, and the main clinical symptoms during follow-up. Results: All the surgical procedures were performed under endonasal endoscope, including Gross total resection in 10 patients. The tumor of a 12-year-old patient was not resected completely due to huge tumor size and limited operation space. One patient was accompanied by two other schwannomas located in the occipital region and the ipsilateral parotid gland region originating from the zygomatic branch of the facial nerve, both of which were removed concurrently. After tumor resection, the dura mater of middle cranial fossa was directly exposed in the nasal sinus in 2 cases, including 1 case accompanied by cerebrospinal fluid leakage which was reconstructed by a free mucosal flap obtained from the middle turbinate, the other case was packed by the autologous fat to protect the dura mater. The operation time was (M(IQR)) 180 (160) minutes (range: 120 to 485 minutes). No complications and deaths were observed. No recurrence was observed in the 10 patients with total tumor resection during a 58 (68) months' (range: 10 to 90 months) follow-up. No obvious change was observed in the facial appearance of all patients during the follow-up. Conclusion: Type D trigeminal schwannoma involving pterygopalatine fossa and infratemporal fossa can be removed safely through purely endoscopic endonasal approach by selecting the appropriate approach according to the size and involvement of the tumor.

Knockdown of ACC1 promotes migration of esophageal cancer cell / 中华肿瘤杂志

Objective: To investigate the effect of acetyl-CoA carboxylase 1 (ACC1) knockdown on the migration of esophageal squamous cell carcinoma (ESCC) KYSE-450 cell and underlying mechanism. Methods: Lentiviral transfection was conducted to establish sh-NC control cell and ACC1 knocking down cell (sh-ACC1). Human siRNA HSP27 and control were transfected by Lipo2000 to get si-HSP27 and si-NC. The selective acetyltransferase P300/CBP inhibitor C646 was used to inhibit histone acetylation and DMSO was used as vehicle control. Transwell assay was performed to detect cell migration. The expression of HSP27 mRNA was examined by reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR) and the expressions of ACC1, H3K9ac, HSP27 and epithelial-mesenchymal transition-related proteins E-cadherin and Vimentin were detected by western blot. Results: The expression level of ACC1 in sh-NC group was higher than that in sh-ACC1 group (P<0.01). The number of cell migration in sh-NC group was (159.00±24.38), lower than (361.80±26.81) in sh-ACC1 group (P<0.01). The protein expression levels of E-cadherin and Vimentin in sh-NC group were statistically significant compared with sh-AAC1 group (P<0.05). The migrated cell number in sh-NC+ si-NC group was (189.20±16.02), lower than (371.60±38.40) in sh-ACC1+ si-NC group (P<0.01). The migrated cell number in sh-NC+ si-NC group was higher than that in sh-NC+ si-HSP27 group (152.40±24.30, P<0.01), and the migrated cell number in sh-ACC1+ si-NC group was higher than that in sh-ACC1+ si-HSP27 group (P<0.01). The protein expression levels of E-cadherin and Vimentin in sh-NC+ si-NC group were significantly different from those in sh-ACC1+ si-NC and sh-NC+ si-HSP27 groups (P<0.01). The protein expression levels of E-cadherin and Vimentin in sh-ACC1+ si-NC group were significantly different from those in sh-ACC1+ si-HSP27 group (P<0.01). After 24 h treatment with C646 at 20 μmmo/L, the migrated cell number in sh-NC+ DMSO group was (190.80±11.95), lower than (395.80±17.10) in sh-ACC1+ DMSO group (P<0.01). The migrated cell number in sh-NC+ DMSO group was lower than that in sh-NC+ C646 group (256.20±23.32, P<0.01). The migrated cell number in sh-ACC1+ DMSO group was higher than that in sh-ACC1+ C646 group (87.80±11.23, P<0.01). The protein expressions of H3K9ac, HSP27, E-cadherin and Vimentin in sh-NC+ DMSO group were significantly different from those in sh-ACC1+ DMSO group and sh-NC+ C646 group (P<0.01). The protein expression levels of H3K9ac, HSP27, E-cadherin and Vimentin in sh-ACC1+ DMSO group were significantly different from those in sh-ACC1+ C646 group (P<0.01). Conclusion: Knockdown of ACC1 promotes the migration of KYSE-450 cell by up-regulating HSP27 and increasing histone acetylation.

After surgery, 3 patients presented with weakness of dorsalis pedis extension and 1 presented with paresthesia of dorsalis pedis, which disappeared after symptomatic treatment . The VAS and WOMAC score at 1 month after operation were lower than those before operation, and the differences were statistically significant(P<0.001). The tension of lateral knee soft tissue 1 month after operation was lower than that before operation, and the difference had statistical significance(P<0.001).@*CONCLUSION@#Proximal fibula osteotomy is safe and effective in the treatment of varus knee osteoarthritis in the short term. One month after osteotomy, the tension of lateral knee soft tissue increases under weight-bearing state, but the long-term changes still need further observation and follow-up.

Incidence and prognosis of olfactory and gustatory dysfunctions related to infection of SARS-CoV-2 Omicron strain: a national multi-center survey of 35 566 population / 中华耳鼻咽喉头颈外科杂志

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.
