In December 2019, an outbreak of pneumonia associated with the coronavirus disease 2019 (COVID-19) occurred in Wuhan, China. The lung imaging finding is like that of the lung cancer immune checkpoint inhibitors (ICI) associated pneumonia. Therefore, we speculated that they may have similar pathogenesis and treatment strategies, which is reviewed in this article in order to provide some reference to timely and effectively reduce the fatality rate of COVID-19.
ObjectiveTo explore the common causes and the clinical pathological characteristics of infant death which occurred after vaccination. MethodsThe study retrospectively analyzed the data of 13 cases of infant death occurring after vaccination from January 2009 to September 2014 in West China Medico-legal Expertise Center. ResultsAmong the 13 cases of infant death, 12 were dead from lethal respiratory system and cardiovascular system diseases, 1 from mechanic asphyxia caused by milk intake. All cases were coupling disease death and had no direct correlation with vaccination. ConclusionSystematic and comprehensive forensic pathological examination is helpful to clarify the cause of death, reveal the relationship between vaccination and the cause of death, and contribute to proper processing of such incidents.
ObjectiveTo explore the risk factors and countermeasures of the perfusionist-related near-miss event (NME) in cardiopulmonary bypass (CPB). MethodsThe clinical data of the patients who underwent cardiac surgery in the Department of Cardiovascular Surgery, Nanfang Hospital, Southern Medical University from March 2020 to July 2021 were retrospectively analyzed. According to whether NME occurred during the operation, the patients were divided into an NME group and a non-NME group. The clinical data of the two groups were compared, and the risk factors for NME were analyzed. ResultsA total of 702 patients were enrolled, including 424 males and 278 females with a median age of 56.0 years. There were 125 patients in the NME group and 577 patients in the non-NME group. The occurrence rate of NME was 17.81%. Univariate analysis showed that there were statistical differences between the two groups in the gender, body surface area, CPB time, European system for cardiac operative risk evaluation score, emergency surgery, type of surgery, night CPB initiation, modified ultrafiltration use, multi-device control, average operation time, et al. (all P<0.05). The above variables were dimensionality reduction processed by least absolute shrinkage and selection operator regression, and the λ of minimum mean square error of 10-fold cross validation was 0.014. The variables of the corresponding model were selected as follows: multi-device control, night CPB initiation, minimum hematocrit, modified ultrafiltration use, CPB time. The results of multivariate logistic regression showed that night CPB initiation [OR=9.658, 95%CI (4.735. 19.701), P<0.01] and CPB time [OR=1.003, 95%CI (1.001, 1.006), P=0.014] were independent risk factors for NME. ConclusionNight CPB initiation and CPB time are independent risk factors for NME during CPB, which should be recognized and early warned in clinical work.
Objective More and more women without child and female adolescents are undergoing medical abortion (MA), MA effect on subsequent pregnancy has been brought into focus. This research will evaluate the effect of MA on subsequent pregnancy. Methods To searched Medline, Embase, Cochrane Library, Chinese Biomed-database, correlative websites and nine Chinese medical journals. The studies that were included in the reference list were additionally searched. Only RCTs (randomized control trials), CCTs (clinical control trials) and prospective cohort studies were included. Two researchers evaluated the quality of the literature and combined the evidence independently. Revman 4.1 was used for meta-analysis. Results Eight prospective cohort studies with 2 934 cases were included. The incidences of miscarriage, postpartum hemorrhage and placental abnormality occurred in MA group were significantly lower than those occurred in SA group, and their OR (with 95%CI) were 0.42 (0.22 to 0.83), 0.58 (0.39 to 0.85) and 0.68 (0.54 to 0.87), respectively. No other significant differences were observed between the two artificial abortions groups. Though the tendency indicates that medical abortion has a probable influence on subsequent pregnancy, there was no significant difference about subsequent pregnancy between MA and first pregnancy. Conclusion Unnecessary abortion should be avoided. MA is safer than SA on subsequent pregnancy, so MA is the preferred option for women without child and female adolescent to terminate their unwilling pregnancy. However, as all the studies included were prospective cohort studies, further high-quality RCTs should be conducted.
Objective To investigate the correlation between D-dimer level within 2 hours on admission and early in-hospital major adverse events (MAEs) in patients with acute type A aortic dissection undergoing arch replacement and the frozen elephant trunk (FET) implantation. Methods The patients with acute type A aortic dissection undergoing arch replacement and the FET implantation, who hospitalized in our hospital from September 2017 to December 2022, were included in this retrospective study. Grouping based on the occurrence of in-hospital major adverse events (MAEs) after total arch replacement and FET implantation, with no in-hospital MAEs as a control group and in-hospital MAEs as an observation group. The perioperative data were compared between the two groups. Univariate and multivariate analyses were used to investigate the risk factors for MAEs (in-hospital mortality, gastrointestinal bleeding, paraplegia, acute kidney failure, reopening the chest, low cardiac output syndrome, cerebrovascular accident, respiratory insufficiency, multiple organ dysfunctionsyndrome, gastrointestinal bleeding, and severe infection). Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of the prediction area under the ROC curve (AUC). Results Finally 218 patients were collected, including 157 males and 61 females with an average age of 51.54±9.79 years. There were 152 patients in the control group and 66 patients in the observation group. In-hospital mortality was 2.8% (6/218). The level of D-dimer, lactic acid, cardiopulmonary bypass time, aortic cross-clamping time, ventilator-assisted time and ICU stay in the observation group were higher or longer than those in the control group (P=0.013). Multivariate logistic analysis showed that D-dimer (OR=1.077, 95%CI 1.020-1.137, P＜0.05) was an independent risk factor for MAEs in hospital. The level of D-dimer within 2 hours admission predicted that the AUC of MAEs in hospital was 0.83 (95%CI 0.736-0.870, P＜0.05), and the optimal critical point was 2.2 μg/mL, with sensitivity and specificity of 84.8% and 73.0%, respectively. Conclusion Increased D-dimer levels at admission are associated with early in-hospital MAEs in the patients with acute type A aortic dissection undergoing arch replacement and FET. These results may help clinicians optimize the risk evaluation and perioperative clinical management to reduce early adverse events.
Tumor immunotherapy includes immune checkpoint inhibitor (ICI), tumor vaccines, and adoptive cell therapy. Immunotherapy, as the main systemic treatment for advanced malignant tumors, kills tumor cells by activating the immune system and prolongs the survival of patients. However, excessive immune responses can cause immune-related adverse events (irAE), causing damage to systemic tissues. ICI are the main tumor immunotherapy drugs that cause optic nerve irAE. The most common optic nerve irAE are optic neuritis, only a few patients appeared arteritic anterior ischemic optic neuropathy. Sudden painless loss of bilateral vision is the most common clinical manifestation. In severe cases, the vision decrease to no light perception. Early diagnosis and early adequate glucocorticoid treatment can improve the symptoms. Therefore, neuro-ophthalmologists and oncologists should know the clinical characteristics of optic nerve irAE, in order to diagnose and treat early and improve the prognosis.
Objective To explore the predictive value of Composite Congestion Score (CCS) in predicting adverse events within 180 days in patients with acute heart failure (AHF) in emergency intensive care unit (EICU). Methods The patients with AHF who were admitted to EICU of Zigong Fourth People’s Hospital between January 1, 2018 and December 31, 2020 were included consecutively. The patients were followed up for 180 days, and were divided into poor prognosis group and good prognosis group according to whether there were adverse events. Logistic regression equation was used to screen independent risk factors for predicting adverse events in patients with AHF within 180 days after leaving EICU. To compare the discrimination, calibration and clinical usefulness of independent risk factors at EICU discharge and the Acute Physiology and Chronic Health Assessment SystemⅡ (APACHEⅡ) score at EICU admission to predict the occurrence of adverse events of AHF. Results A total of 71 patients were included, including 32 patients with good prognosis and 39 patients with poor prognosis. Except for age, APACHEⅡscore at EICU admission and CCS score at EICU discharge (P<0.05), there was no significant difference in other indicators between the two groups (P>0.05). Logistic regression analysis showed that CCS score at EICU discharge [odds ratio (OR)=2.806, 95% confidence interval (CI) (1.428, 5.512), P=0.003], age [OR=1.086, 95%CI (1.017, 1.159), P=0.013] were independent risk factors for predicting death or returning to hospital within 180 days. Among them, the CCS score at EICU discharge combining with age had a positive improvement ability compared with the CCS score at EICU discharge, the age, and the APACHE Ⅱ score at EICU admission. The calibration curves of the four scoring methods for predicting adverse events within 180 days showed that the CCS score at EICU discharge had the highest calibration and the calibration of age was the lowest. The decision curve showed that the clinical usefulness of age, the CCS score at EICU discharge and the CCS score at EICU discharge combining with age was better than the APACHE Ⅱ score at EICU admission. Conclusions The CCS score of patients with AHF at EICU discharge is closely related to adverse events within 180 days. The CCS score is designed based on clinical variables, simple and practical. The combination of age and the CCS score at EICU discharge will further enhance its clinical application value.
The tyrosine kinase activity of epidermal growth factor receptor (EGFR) plays a key role in tumor cell proliferation, invasion, migration, and drug resistance. Studies have shown that non-small cell lung cancer patients with somatic driver gene EGFR mutations are sensitive to and can benefit from EGFR-tyrosine kinase inhibitors (EGFR-TKIs). Nevertheless, EGFR-TKIs-related adverse events should not be ignored. Common adverse events such as diarrhea, acne-like rash and paronychia are usually manageable; although the incidence of interstitial lung disease is low, once it occurs, it is a serious threat to patients' life, and its pathogenesis is still unclear. There is very limited animal experimental and clinical research evidence on the potential mechanism of EGFR-TKIs-related interstitial lung disease in the available literature. Based on this, this article reviews the association between EGFR-TKIs and interstitial lung disease, at the same time, also discusses the research progress of EGFR-TKIs-related interstitial lung disease in combination with cytotoxic drugs or immunotherapeutic drugs and EGFR-TKIs, in order to provide a reference for the prevention and treatment of EGFR-TKIs-related interstitial lung disease in clinical practice in the future.
Lung cancer is the leading cause of cancer-related deaths worldwide. Although improvement has been achieved in platinum-based chemotherapy and tyrosine kinase inhibitors-based molecular targeted therapy, they still have limitations. Immunotherapy has recently emerged as a very effective new treatment, and there is now growing enthusiasm in cancer immunotherapy worldwide. We summarized the effects of immune checkpoint inhibitors in clinical trials, and the current status and progress of anti programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1) agents in lung cancer treatment. Attention has been paid to finding out the factors which influence the therapeutic effect of anti-PD-1/PD-L1 therapy and reducing the occurrence of adverse events.
Objective Risk factors for real-word immune checkpoint inhibitor-related pneumonitis in patients with lung cancer were analyzed by systematic analysis. Methods Computerized retrieval of PubMed, EMbase, Web of Science, the Cochrane Library , WanFang Data, CNKI and VIP databases was carried out. Studies were collected from the database establishment to March 2023. Three researchers independently screened the literature, extracted data, and evaluated the risk of bias in the included studies. Meta-analysis was performed using RevMan5.4.1software. Results A total of 18 studies were included with a total of 4 990 patients. The results of meta-analysis showed that, interstitial pneumonia [odds ratio (OR)=9.32, 95% confidence interval (CI) 4.66 - 18.67, P<0.01], smoking history (OR=2.39, 95%CI 1.29 - 4.45, P<0.01), chronic obstructive pulmonary disease (COPD) (OR=5.54, 95%CI 2.96 - 10.36, P<0.01), chest radiotherapy (OR=2.74, 95%CI 1.80 - 4.19, P<0.01), pulmonary fibrosis (OR=7.46, 95%CI 4.25 - 13.09, P<0.01), high programmed death ligand 1 (PD-L1) expression (OR=2.98, 95%CI 1.71 - 5.22, P<0.01), high absolute eosinophil count (AEC) (OR=3.92, 95%CI 2.17 - 7.08, P<0.01) and pembrolizumab (OR=2.90, 95%CI 1.56 - 5.37, P<0.01) were independent risk factors for immune checkpoint inhibitor-related pneumonitis in lung cancer patients. Conclusions Interstitial pneumonia, smoking history, COPD, Chest radiotherapy, pulmonary fibrosis, high PD-L1expression, high AEC and pembrolizumab are independent risk factors for immune checkpoint inhibitor-related pneumonitis in lung cancer patients. Due to insufficient evidence on the risk factors of low albumin, more studies are needed to further identify it.
