Video-electroencephalogram (VEEG) monitoring is a valuable tool for diagnosing recurrent partial epilepsy, classification of intractable epilepsy, and evaluation of epilepsy surgery. The role of video EEG in identifying and determining the type of epilepsy and determining the location of seizures has been widely demonstrated, but there is There is a lack of uniform standards for adverse events and management methods during monitoring. In order to improve the quality of long-range video EEG monitoring and reduce the possible impact on patients during monitoring, it is necessary to summarize the possible adverse reactions during monitoring.
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.
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 systematically evaluate the safety of dipeptidyl peptidase-4 (DPP-4) inhibitors on the risk of cardiovascular events in type 2 diabetes mellitus (T2DM) patients. MethodsDatabases such as the Cochrane Library, PubMed, Elsevier ScienceDirect and EMbase were searched to collect randomized controlled trials (RCTs) about DPP-4 inhibitors for T2DM patients from inception to February 2014. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and assessed the methodological quality of included studies. Then, meta-analysis was performed using RevMan5.2 software. ResultsA total of 20 RCTs involving 10 402 patients were included. The results of meta-analysis showed that:there were no significant differences between the DPP-4 inhibitors group and the control group in the cardiovascular adverse events (RR=0.86, 95%CI 0.62 to 1.20, P=0.38) and acute coronary syndrome (RR=0.66, 95%CI 0.37 to 1.17, P=0.15). Subgroup analyses by type of liptins and durations showed there were lower risks of adverse cardiovascular events in the DPP-4 inhibitors group of the sitagliptin subgroup (RR=0.49, 95%CI 0.29 to 0.82, P=0.007) and the duration of ≥52 weeks subgroup (RR=0.62, 95%CI 0.39 to 0.97, P=0.04). No significant difference was found between the two groups in hypertension events (RR=1.09, 95%CI 0.84 to 1.40, P=0.52). ConclusionThe DPP-4 inhibitors are relatively safe. In the long-term treatment of T2DM, the sitagliptin could not only effectively control the level of blood sugar but also might obtain benefits in cardiovascular aspects.
ObjectiveTo develop and validate a Nomogram for predicting severe immune-related adverse events (irAEs) in patients with advanced non-small cell lung cancer (NSCLC) undergoing immunotherapy based on clinical features and inflammatory indicators. MethodsA total of 423 patients with advanced NSCLC treated with immunotherapy between January 2023 and January 2025 at Tianjin Fourth Center Hospital and Tianjin Cancer Hospital Airport Hospital were enrolled. Patients were divided into a severe irAEs group (≥grade 3, n=76) and a non-severe irAEs group (n=347), then randomly allocated into training and validation cohorts (7:3 ratio) . Clinical data, neutrophil-to-lymphocyte ratio (NLR), and interleukin-6/C-reactive protein (IL-6/CRP) levels were collected. Independent risk factors for severe irAEs during immunotherapy in advanced NSCLC were identified through logistic regression analysis, and a nomogram model was constructed accordingly. The discriminative ability, accuracy, and clinical utility of the model were evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). ResultsAmong the 423 included patients [274 males, 149 females, aged 44-78 (60.77±5.91) years], the overall incidence of irAEs was 57.92% (245/423), with severe irAEs occurring in 17.97% (76/423). Multivariate analysis revealed that Eastern Cooperative Oncology Group (ECOG) performance score ≥2, programmed death-ligand 1 (PD-L1) expression [tumor proportion score (TPS) ≥50%], combination therapy regimen, low NLR values, and high IL-6/CRP ratio were independent risk factors for severe irAEs during immunotherapy in advanced NSCLC (P<0.05). The area under the ROC curve (AUC) was 0.948 [95%CI (0.912, 0.985)] in the training cohort and 0.946 [95%CI (0.917, 0.976)] in the validation cohort. Calibration curves and DCA demonstrated good consistency and clinical net benefit of the model. ConclusionThe nomogram integrating clinical features and inflammatory markers effectively predicts the risk of severe irAEs in advanced NSCLC patients receiving immunotherapy, exhibiting excellent discrimination, calibration, and clinical practicality.
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.
Stem cell transplantation is one of the main methods to treat thromboangiitis obliterans (TAO). In recent years, research on the treatment mechanism of stem cell transplantation has made some progress. The results of a number of stem cell clinical trials specifically for TAO have been published. Some new stem cell types have gradually been used in the clinic. There is no major dispute over security. In addition, research shows that the efficacy of stem cell transplantation is affected in many ways, and some factors have a certain predictive effect on the possibility of amputation after transplantation. This paper reviews the clinical research progress of stem cell transplantation for TAO, and aims to provide some basis for the better use of stem cell transplantation in the treatment of TAO.
Objective To construct a risk prediction score model for serious adverse event (SAE) after cardiac catheterization in patients with adult congenital heart disease (ACHD) and pulmonary hypertension (PH) and verify its predictive effect. Methods The patients with PH who underwent cardiac catheterization in Wuhan Asian Heart Hospital Affiliated to Wuhan University of Science and Technology from January 2018 to January 2022 were retrospectively collected. The patients were randomly divided into a model group and a validation group according to the order of admission. The model group was divided into a SAE group and a non-SAE group according to whether SAE occurred after the catheterization. The data of the two groups were compared, and the risk prediction score model was established according to the results of multivariate logistic regression analysis. The discrimination and calibration of the model were evaluated using the area under the receiver operating characteristic (ROC) curve and the Hosmer-Lemeshow test, respectively. Results A total of 758 patients were enrolled, including 240 (31.7%) males and 518 (68.3%) females, with a mean age of 43.1 (18.0-81.0) years. There were 530 patients in the model group (47 patients in the SAE group and 483 patients in the non-SAE group) and 228 patients in the validation group. Univariate analysis showed statistical differences in age, smoking history, valvular disease history, heart failure history, N-terminal pro-B-type natriuretic peptide, and other factors between the SAE and non-SAE groups (P<0.05). Multivariate analysis showed that age≥50 years, history of heart failure, moderate to severe congenital heart disease, moderate to severe PH, cardiac catheterization and treatment, surgical general anesthesia, and N-terminal pro-B-type natriuretic peptide≥126.65 pg/mL were risk factors for SAE after cardiac catheterization for ACHD-PH patients (P<0.05). The risk prediction score model had a total score of 0-139 points and patients who had a score>50 points were high-risk patients. Model validation results showed an area under the ROC curve of 0.937 (95%CI 0.897-0.976). Hosmer-Lemeshow goodness-of-fit test: χ2=3.847, P=0.797. Conclusion Age≥50 years, history of heart failure, moderate to severe congenital heart disease, moderate to severe PH, cardiac catheterization and treatment, general anesthesia for surgery, and N-terminal pro-B-type natriuretic peptide≥126.65 pg/mL were risk factors for SAE after cardiac catheterization for ACHD-PH patients. The risk prediction model based on these factors has a high predictive value and can be applied to the risk assessment of SAE after interventional therapy in ACHD-PH patients to help clinicians perform early intervention.
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.
